Background: Publication and co-authorship rates have been increasing over decades. In response, calls are being made to restrict the number of publications included in research evaluations. Yet there is little evidence to guide publication expectations and inform research evaluation for early career researchers (ECRs). Methods: Here we examine the early career publication and co-authorship records between 1970 and 2019 of >140,000 authors of 2.8 million publications, to identify how publication and co-authorship rates have changed over the last 50 years. This examination is conducted in order to develop benchmarks of median publication rates for sensibly evaluating ECR research productivity, and to explore success in meeting these benchmarks with different co-authorship strategies using regression models. Results: Publication rates of multidisciplinary ECRs publishing in Nature, Science and PNAS have increased by 46% over the last 50 years and that publications rates in a set of disciplinary journals have increased by 105%. Co-authorship rates have increased even more, particularly for the multidisciplinary sample which now has 572% more co-authors per publication. Benchmarks based on median publication rates for all authors increased from one publication per year at the start of a career, to four publications per year after 10 years of publishing, and one first-author publication across all years. The probability of meeting these benchmarks increases when authors publish with different co-authors, and first authorship rates decrease for ECRs with many co-authors per publication. Conclusion: This evidence could be used to inform sensible publishing expectations for ECRs and the institutions they work for, and to inform calls to limit the number of publications produced by researchers and those used in research evaluations.

Background This study conducted a comprehensive bibliometric analysis to identify the gaps in the existing literature related to Online marketing and brand awareness strategies for HEI. It has evaluated the current state of the literature on the given topic showing the pivotal role of online marketing and brand awareness in higher education for enrollment. Methods The study used a web-based application, Biblioshiny, which comes in the bibliometrix package. The study used the Scopus database to create the data set, given its conventional construction and quality of the sources. The analysis done is descriptive. By using the bibliometrix software, the study showed the authors name, articles, sources, citations, relevant journals and co-citation from the year 2017 to 2022. The time period selected by the study was five years which means that articles published from 2017 to 2022 have been taken for the study. Results We found that HEI online marketing and brand awareness have not been explored much as it has not reached the stage of maturity. Most of the publication was done during the time of Covid-19. Also, the role of brand awareness in student enrollment decisions for HEI requires more investigation. Top most publications their sources and top authors are identified. Conclusions Bibliometric analysis has provided valuable insights into the seminal work, emerging trends, and the gap in the study. This area of study has been explored but not as much as challenges, and the effectiveness of online marketing tools like seo, sem,ppc and more has not been measured. Further, this paper allows researchers to study by examining the pattern of publications by seeing the different authorships, co-authors, collaborations, relevant sources, and citations. The insights of this paper will help education policymakers devise more creative strategies to increase enrollment, ensuring sustained relevance and competitive advantage in higher education institutions .

Fondrakö is the local wisdom of the Nias ethnic community and has two functions. First are the oral religious holy book teaching ancestors' values and philosophy. Second is the highest consensus institution of the traditional society formulating and making decisions on the socio-religious law to guarantee the order of the community. This paper explains that social differentiation has happened in the modern era; philosophical values of fondrakö remain to live up to this day and experience the proliferation of rites. The argumentation built through this paper is that primitive culture will not simply disappear in the modern community just because it experiences accommodation and the decrease of emotional intensity into new forms. Social laws of primitive religion are not always contradictory and can run parallel with civilization.

Background: With the tremendous increase in the usage of smart meters for industrial/ household purposes, their implementation is considered a crucial challenge in the Internet of Things (IoT) world, leading to a demand for emerging 5G technology. In addition, a large amount of data has to be communicated by smart meters efficiently, which needs a significant enhancement in bandwidth. The power amplifier (PA) plays a major role in deciding the efficiency and bandwidth of the entire communication system. Among the various modes of PAs, a newly developed Class-J mode PA has been proven to achieve high efficiency over a wide bandwidth by maintaining linearity. Methods: This paper proposes a Class-J mode PA design methodology using a CGH40010F-GaN device that operates at a 3.5 GHz frequency to meet the requirements of 5G wireless communication technology for the replacement of existing 4G/LTE technology used for advanced metering infrastructure (AMI) in smart grids. This research's main objective is to design the proper matching networks (M.Ns) to achieve Class-J mode operation that satisfies the bandwidth requirements of 5G smart grid applications. With the target impedances obtained using the load-pull simulation, lumped element matching networks are analyzed and designed in 3 ways using the ADS EDA tool. Results: The simulation results reveal that the proposed Class-J PA provides a maximum drain efficiency (D.E) of 82%, power added efficiency (PAE) of 67% with 13 dB small-signal gain at 3.5 GHz, and output power of 40 dBm (41.4 dBm peak) with a power gain of approximately 7 dB over a bandwidth of approximately 400 MHz with a 28 V power supply into a 50 Ω load. Conclusion: The efficiency and bandwidth of the proposed Class-J PA can be enhanced further by fine-tuning the matching network design to make it more suitable for 5G smart meter/grid applications.

Purpose: An increasing number of scholarly publications on autism spectrum disorder (ASD) have urged researcher interest in this topic; however, there is still a lack of quantitative analysis. Therefore, this study aims to cover the knowledge gap between the amount of literature published on ASD research on architectural and designers' perspectives compared to the medical and psychological fields. The study has analyzed global research output on ASD from a designer's perspective to recognize this gap related to designing the physical environment. Methodology: The bibliometric method was employed to analyze the published literature from 1992–to 2021. 812 papers were downloaded from the Web of Science for analysis based on annual growth of literature, prolific authors, authorship pattern, organizations, countries, international collaboration, and subject development by keywords and thematic map analyses. Various bibliometric and scientometric software was used to analyze the data, namely Bibexcel, Biblioshiny, and VOS viewer. Results: The812 research papers were published in 405 sources. 2019 appeared as a productive year (NP=101), and 2014 received the highest number of citations (TC=6634). Researchers preferred to publish as journal articles (NP=538; TC=24922). The University of Toronto, Canada, was identified as a productive institution with 42 publications and 5358 citations. The USA was the leading producing country with 433 publications, and most of the researchers published in the journal ' Scientific Reports' (NP=16). The word autism (NP=257) and architecture (NP=165) were more frequently used keywords. Conclusion: The study identified a massive gap in the development of literature in ASD for architecture design and built environment perspective, the most important and trending keywords are missing, and the analyses also showed a lack of subject development. The authors have suggested areas and keywords for further research to fulfill the gap in the future.

Background This paper examines the impact of financial inclusion on bank stability within Ethiopian context, using panel data from 17 commercial banks over the period 2015-2023. Given the scarcity of research focused on the relationship between financial inclusion and bank stability in Ethiopia, this paper seeks to address a crucial gap by analyzing both conventional and digital aspects of financial inclusion in relation with bank stability. Methods A two-stage principal component analysis (PCA) was conducted to construct a composite financial inclusion index, integrating 10 conventional and 5 digital indicators. The study applied a two-step robust system generalized method of moments (GMM) to examine the effects of financial inclusion on bank stability, complemented by Granger causality testing to examine the directionality of this relationship. Results The result reveals a significant positive effect of financial inclusion on bank stability and Granger causality tests confirms a bi-directional relationship between financial inclusion and stability, indicating that improvements in financial inclusion foster greater stability and vice versa. Our results also highlight that while bank efficiency and GDP growth rate positively effect stability, total assets and income diversification exhibit detrimental effects. Conclusions It is essential to capitalize policy synergies to promote bank stability and to enhance financial inclusion through conventional and digital channels, while carefully managing the implications of risks associated with income diversification and asset distribution. Ensuring inclusive financial system is vital for maintaining bank stability, thus positioning it as a key priority for financial institutions.

Background Moldova strives for universal health coverage (UHC) and considers health technology assessment (HTA) an important policy instrument to inform the choice of services that should be covered to progressively realize UHC. It plays a key role in determining which technologies are coved, considering various dimensions often including cost-effectiveness, budget impact, and feasibility. This paper reports on work undertaken to develop a roadmap for HTA implementation, using evidence-informed deliberative processes (EDPs) as the guiding framework. Methods Between 2020 and 2022, we undertook several activities that informed the roadmap. We conducted a needs assessment and an assessment of European HTA best practices using a combination of desk research, interviews and surveys. We then conducted a document review of six selected HTA systems, complimented by expert interviews from three neighbouring countries. Results The roadmap provided a suggested HTA process, which included instructions on how to execute the different steps of the EDP framework to enhance the legitimacy of HTA-informed decision-making. The roadmap encompasses several aspects such as how to organize stakeholder involvement, how to identify and operationalize decision criteria, and how to make the decision process transparent. Guidance was given to the country on establishing a legal framework for HTA; a communication strategy; strengthening capacity and leveraging HTA expertise. The country was also given tailored advice on the positioning of the HTA-agency, first as an entity within the Ministry of Health or the National Agency of Public Health but with the long-term vision for it to be independent of any state institution. Conclusions Despite several challenges, including a partial disruption because of the Covid-19 pandemic, the development of the roadmap for HTA implementation was completed and agreed upon by the Ministry of Health in Moldova. This work has helped motivate and support the country in HTA institutionalization.

Background The towering peaks of the Himalayas lie in troves of captivating hill destinations, especially in India. Each destination aims to provide tourists with unique experiences and breath-taking landscapes. Understanding the tapestry of factors that weave the allure of these destinations and draw visitors from diverse backgrounds remains intriguing. Method This study delves into the socio-demographic tapestry of Himalayan hill destination selection, unraveling the complex interplay of demographic characteristics, social influences, and individual motivations that shape tourists’ choices. Results This study aims to answer why different tourists have different travel choices and what factors are the drivers behind such choices. The results show that destination selection factors are similar irrespective of respondents’ socio-demographic variabilities; however, for a few factors, the results are reversed. Conclusion The study has implications for policymakers and the limitations of the research discussed at the end.

Background This study delved into the experiences and approaches employed by junior teachers in facilitating practical work in Natural Sciences during the teaching and learning process. In South Africa, Grade 7 marks the final year of primary school education, with learners typically aged between 11 to 13. The researchers noted significant challenges faced by junior Grade 7 teachers in preparing, organizing, and carrying out practical work within the context of teaching and learning in Natural Sciences. Methods In the present study, a qualitative multiple-case study design was employed. Three grade 7 Natural Sciences junior-level teachers were purposefully selected as participants. Data was gathered through classroom observations, semi-structured interviews, and document analysis. Results The study findings revealed that certain grade 7 junior Natural Sciences teachers found it challenging to manage practical work during teaching and learning. Some teachers also faced difficulties in maintaining discipline during practical work and demonstrations, both inside and outside the classroom. To cope with the demands of facilitating practical work in Natural Sciences teaching and learning, teachers employed various approaches, such as group work, observations, demonstrations, illustrations, projects, and inquiry-based scientific investigations. Conclusion It is recommended that teachers should receive professional training on effectively facilitating practical work to support the new teaching and learning methods outlined in the Curriculum Assessment Policy Statement. They should also be equipped with pedagogical content knowledge to help them achieve the goals of practical work in teaching and learning Natural Sciences.

Background This article aims to study the research outcomes of five Nordic countries in terms of research publications, spend on R&D, outcomes and collaborations as these are important parameters to understand research thrust of the countries/regions, in addition to their innovation capability. Methods The research outcomes of the Nordic countries in terms of the total number of publications, coauthored publications, publications with corporate collaborators, citations, the Field Weighted Citation Index (FWCI) and publications in different subject areas were retrieved using Scopus and its associate SciVal. The research outcomes were extracted for five years from 2016-2020. In addition, total population, researcher population and research spend of these countries have been obtained from World Bank data available for the year 2021. Results The analysis showed that Sweden has the highest population and the highest number of researchers in this region. All countries have the highest number of coauthored publications with the United States, followed by the United Kingdom, except Iceland, which has the second highest number of coauthored publications with Sweden. Denmark, followed by Iceland, stands prominent with reference to having publications with corporate collaborations. Denmark and Sweden have a high percentage of articles in first quartile journals, which is above the average for Nordic countries. Iceland stands at the top with the highest citations, which is depicted by high FWCI. Across subject areas, the Nordic countries have maximum publications in life sciences. Other prominent subject areas include technology and natural sciences. Conclusion On analysing the research landscape of Nordic countries, maximum research output is in the field of life sciences and medicine, and most of the coauthored publications of these countries are with the United States. Denmark, with its exemplary research output, excels with maximum papers in top quartile journals and with maximum corporate collaborations and the highest FWCI.

Background Religion and its exercise are among the most sensitive discourses in different parts of the world, especially in Nigeria. The constitution and other laws ensure citizens are afforded basic human rights of which religious rights are included and yet regulated. There are questions of interpretation as to the extent to which such rights can be enjoyed and the efficacy of both the legal and institutional frameworks protecting religious rights in Nigeria. Methods This article utilises a doctrinal legal research approach utilising existing literature, statutes, and laws enacted towards the protection of religious rights in Nigeria with the consideration of primary and secondary sources of statutes including the 1999 Constitution of the Federal Republic of Nigeria (as amended), judicial precedents, International Conventions, law textbooks, and peer-reviewed journals. A comparative analysis of Nigeria, Tunisia, Algeria, Turkey and Kazakhstan was done to gain perspectives on balancing conflicting interests in light of Nigeria’s heterogeneous status. As part of the contribution to knowledge, a hybrid model for mitigating the socio-legal effect of the usage of hijab in Nigeria’s public institutions is presented to further enrich Nigeria’s jurisprudence. A hybrid model is an approach that combines different sources or methodologies by integrating two or more distinct frameworks to leverage their strengths and effectively address specific needs or challenges. It is utilized to achieve synergy and maximize outcomes by blending diverse legal approaches in law. Results Nigeria, being a multi-ethnic and multi-religious state, demonstrates that the government must protect the public interests as it relates to religious rights regardless of faith or religion. The study reveals that the current legal approach without further legislative intervention on religious issues will be inadequate to address the problem. Therefore, this study presents a hybrid model for mitigating the socio-legal effect of the usage of hijab in Nigeria’s public institutions to avoid harm and further enrich Nigeria’s jurisprudence. Conclusions This study concludes by emphasizing the inadequacy of Nigeria’s legal and institutional frameworks regarding the protection of religious rights and the right to wear hijab in public institutions. Consequently, reform is deemed necessary.

Background The aim of this paper was to explore how the Fourth Industrial Revolution shapes teaching and learning during COVID-19 in some of the schools located in the Gauteng and Mpumalanga provinces, South Africa. This paper employed qualitative interpretative multiple case study design. Purposive sampling was used to sample our participants. Methods We selected four teachers who separately taught at the early childhood development stage, intermediate phase, senior phase, and further education and training phases. Data was collected telephonically through semi-structured interviews with teachers from Limpopo, Gauteng and Mpumalanga provinces of South Africa. Data was collected from their experiences of COVID-19 from 2019 to 2021. Collected data was analysed using a typology approach whereby themes that derived from the literature reviewed and research questions were used. Results We inferred from the results of the paper that teachers had challenges with teaching and availability of learning resources, such as limited access to internet and socio-economic backgrounds, which hindered the integration of the Fourth Industrial Revolution in the teaching and learning process. There were also challenges related to teachers’ background on the usage of the Fourth Industrial Revolution and the lack of school management teams support. The paper revealed that the integration of the Fourth Industrial Revolution in teaching and learning was affected negatively by the existence of the above-mentioned challenges, which needs to be addressed. Conclusions Therefore, we recommended that the government and stakeholders within the education sector provide resources such as smart-boards, computers, and network access in schools lacking such facilities, as well as providing professional development interventions and training teachers to have an in-depth understanding of the Fourth Industrial Revolution within the teaching and learning context.

Background In this paper we analyse the novel The End of Eddy by Édouard Louis. The motivation for this paper is Bourdeau’s (2020) observation that Louis’s book explores working class politics, sexuality, and masculinity. Methods We analysed the amendment through narrative content analysis, the application of which allows us to answer the following question: Édouard Louis’s novel The End of Eddy: A representation of hegemonic masculinity? Results We conclude that this narrative is built on contradictions that can be summarized as a conflict between a socio-cultural norm anchored in a French village and a person who does not fulfil this concept, who is outside of it. We believe that hegemonic masculinity, that is, one part of the cultural norm of a given village, causes Eddy’s inclination or consciousness of homonationalism. Thus, on the one hand, hegemonic masculinity is undoubtedly present in this novel; on the other hand, it forms a kind of background or socio-cultural environment which, although it defines itself against the given, unconsciously causes the “birth of the conscious homosexual”. Conclusions Thus, we dare to claim that the narrative under analysis is not only a representation of hegemonic masculinity, but also an accentuation of its external and internal influence on one’s own perception of (sexual) difference.

Background: Babies cannot communicate their pain properly. Several pain scores are developed, but they are subjective and have high variability inter-observer agreement. The aim of this study was to construct models that use both facial expression and infant voice in classifying pain levels and cry detection. Methods: The study included a total of 23 infants below 12-months who were treated at Dr Soetomo General Hospital. The the Face Leg Activity Cry and Consolability (FLACC) pain scale and recordings of the baby's cries were taken in the video format. A machine-learning-based system was created to detect infant cries and pain levels. Spectrograms with the Short-Time Fourier Transform were used to convert the audio data into a time-frequency representation. Facial features combined with voice features extracted by using the Deep Learning Autoencoders was used for the classification of infant pain levels. Two types of autoencoders: Convolutional Autoencoder and Variational Autoencoder were used for both faces and voices. Result: The goal of the autoencoder was to produce a latent-vector with much smaller dimensions that was still able to recreate the data with minor losses. From the latent-vectors, a multimodal data representation for Convolutional Neural Network (CNN) was used for producing a relatively high F1 score, higher than single data modal such as the voice or facial expressions alone. Two major parts of the experiment were: 1. Building the three autoencoder models, which were autoencoder for the infant’s face, amplitude spectrogram, and dB-scaled spectrogram of infant’s voices. 2. Utilising the latent-vector result from the autoencoders to build the cry detection and pain classification models. Conclusion: In this paper, four pain classifier models with a relatively good F1 score was developed. These models were combined by using ensemble methods to improve performance, which resulted in a better F1 score.

Background: Low-density parity-check (LDPC) codes are more error-resistant than other forward error-correcting codes. Existing circuits give high power dissipation, less speed, and more occupying area. This work aimed to propose a better design and performance circuit, even in the presence of noise in the channel. Methods: In this research, the design of the multiplexer and demultiplexer were achieved using pass transistor logic. The target parameters were low power dissipation, improved throughput, and more negligible delay with a minimum area. One of the essential connecting circuits in a decoShder architecture is a multiplexer (MUX) and a demultiplexer (DEMUX) circuit. The design of the MUX and DEMUX contributes significantly to the performance of the decoder. The aim of this paper was the design of a 4 × 1 MUX to route the data bits received from the bit update blocks to the parallel adder circuits and a 1 × 4 DEMUX to receive the input bits from the parallel adder and distribute the output to the bit update blocks in a layered architecture LDPC decoder. The design uses pass transistor logic and achieves the reduction of the number of transistors used. The proposed circuit was designed using the Mentor Graphics CAD tool for 180 nm technology. Results: The parameters of power dissipation, area, and delay were considered crucial parameters for a low power decoder. The circuits were simulated using computer-aided design (CAD) tools, and the results depicted a significantly low power dissipation of 7.06 nW and 5.16 nW for the multiplexer and demultiplexer, respectively. The delay was found to be 100.5 ns (MUX) and 80 ns (DEMUX). Conclusion: This decoder’s potential use may be in low-power communication circuits such as handheld devices and Internet of Things (IoT) circuits.

Background: Over the previous few decades, trends in author demographics have significantly changed. Such trends have already been studied for many sub-specialties but endocrinology is among the few branches that are yet to see an analysis of such trends. This paper aims to fill this gap. Methods: Journal of Endocrinology and General & Comparative Endocrinology are two landmark journals that publish articles from around the world. Each decade during the 70-year period from 1961 to 2021 has been examined in this study. Funding source, first author – senior author gender, their demographics and proportion of papers with at least one female author were the parameters considered while studying each publication. It was predicted that the number of female authors per paper would increase with time, as would the range of degrees held by the authors, demographical variations in authorship, and the funding source. The aim was also to determine the distribution of female first authors and senior authors in endocrinology journals over a 70-year period, as well as to check the gender combinations using the Punnett square. Results: Female first authors rose from 7% to 29.6% (p Conclusion: In papers published in endocrinology journals, there was a rising trend in female contributions to academic medicine. Even with the large growth of female endocrinologists, there is still a disparity in why the increase in female authors is comparably fewer.

Background: Microsoft Windows Security is a recently implemented safeguard for the Windows operating systems, including the latest versions of Windows10 and 11. However, there is a major shortcoming in this system to stop Advanced Persistent Threat (APT). These are government-financed groups that are funded to attack other government entities. Following the initial security breach, the hacked Windows device is used to access the rest of the network devices in order to transfer data to external storage (Exfiltration). Methods: In this work, we have tested the Microsoft Windows Security system using MITRE CALDERA and ATT&CK frameworks and explain how APT groups are able to bypass Windows Security. Results: In this study we used '54ndc47' agent through GoLang feature in MITRE CALDERA platform to test and bypass Microsoft Windows Security systems (MS Windows 10). Through it, we were able to bypass the Windows Security system and display entire files in the victim's device. Conclusions: In this paper, we have provided recommendations to Microsoft to improve their Windows Security tool through the use of Artificial intelligence (AI).

Background Co-infection of hepatitis B virus (HBV) and human immunodeficiency virus (HIV) has an impact on high HBV replication and progression to liver cancer. These may lead to cross-resistance of drugs due to therapeutic pressure or liver toxicity. These require continuous monitoring of HBV variants for better diagnosis and treatment strategies. Methods Convenience sampling was used to collect fifty archival sera from Inkosi Albert Luthuli Central Hospital. The Sera were subjected to HBsAg screening using ELISA, DNA extraction, PCR amplification, Sanger sequencing, phylogenetic and mutation analysis. A correlation test was performed to measure the association between polymerase and surface mutations. Results Of the 50 samples, 86% (N= 43/50) were HBsAg positive; 82% (N=41/50) PCR positive and 92% (N=38/41) sequenced. The HBV sequences showed similarity to genotype A (73% [N=19/26]) and (24% [N=7/26]) as genotypes B, C, D, E, F, and G. Prevalence of the mutations in the Surface region was (47% [N=18/38]); including diagnostic failure (K122R and T143S) and vaccines escape mutations (P127T, G145R, S207N, Y200T, E164D, Y206H and L209V). The mutations in the RT was at (36% [N=14/38]) with drug resistance mutations (DRM) at (50% [7/14]). Mutations showed resistance to lamivudine (LMV) at (35% [5/14]), telbivudine (LdT) at (29% [4/14]), (14% [2/14]) for entecavir (ETV) and (21% [3/14]) for adefovir (ADV). One sample had a combination of L180M, M204V, S202K, and M250I mutations. There was no statistical significance between S and RT mutations at P>0.005 and the statistical correlation between RT and SHB mutations was weak at 0.877. Conclusions Our findings highlight the prevalence of HBV genotype A in HIV-infected patients in South Africa. We provide evidence of mutations linked to immune evasion and drug resistance. Mutations have no statistical significance but can have clinical Implication on the diagnosis and treatment of HBV in HBV/HIV co-infected individuals.

Background Bibliometric analysis plays an essential role in scientific research. However, some research areas still have several gaps. This is also the case in the animal sciences. Therefore, the status of current studies can be analyzed to provide guidance for future research through scientific studies that will be conducted. The aim of this study was to perform a bibliometric analysis of goat breeding to evaluate current trends, gaps in knowledge, and future perspectives. Methods A large dataset was extracted from the Web of Science (WoS), a popular database for scientific studies. According to the WoS, we used 1000 scientific papers (1991–2023) that contained articles, book chapters, data papers, proceedings papers, meeting abstracts, and notes. All bibliometric analyses were performed using the bibliometrix package. Results and Conclusions In 2023, there were 34 studies available. Average citations per year showed that the highest average citation count occurred in 2006 (31.35). In total, 265 scientific journals in the WoS database have published goat breeding studies. Small Ruminant Research led to the remaining 145 articles. In conclusion, scientific studies on goat breeding have become popular in recent years. The authors may gravitate towards popular journals in the future.

Introduction Traumatic spinal spondyloptosis, though rare, harbingers a high risk of mortality as well as permanent and disabling neurological deficits. They invariably become socially aloof and marginalized in most parts of our subcontinent owing to the lack of dedicated rehabilitation units amid their poor economic status. There is a paucity of studies pertaining to such rare epiphenomenon within our region. Materials ad Methods A retrospective study of 16 patients presenting with spinal spondyloptosis in a tertiary care center in Nepal was undertaken. The clinical records of the patients were retrieved from the hospital record section to study the demographic variables, modes of injury, American Spinal Injury Association (ASIA) grades, salient radiological characteristics, management strategies, and the resultant clinical outcomes. Result The mean age of the cohorts in our study was 40 years with an age range of 25-80 years. Most of the patients presented in ASIA ‘A’ neurological grade (75%). The cervical spine was involved in the majority (68.75%) of cases. 8 (50%) patients left against medical advice, 2 (12.5%) were managed conservatively, and 6 (37.5%) were operated. The posterior-only approach was undertaken in 4(66.67%) cases. Tracheo-oesophageal fistula occurred in 2 (33.33%) patients. And cerebrospinal fluid (CSF) leak occurred in 2 (33.33%) patients. The overall hospital mortality was 3(37.5%). Conclusion Traumatic spinal spondyloptosis on our center mostly involved cervical spine (68.75%). 75% of the patients presented with ASIA ‘A’ neurological grade. 50% of them left against medical advice. 37.5% were operated. The overall hospital mortality was 37.5%. This study emphasizes the implementation of a national spinal trauma data bank and the systematic implementation of dedicated neuro-rehabilitation units. This will thereby help improve the clinical outcome among these ‘socially aloof’ and marginalized subsets of neurosurgical patients.

Background Families, friends and support networks are key to managing bereavement. COVID-19 social restrictions prevented families and friends from being with the dying and participating in usual rituals to honour the dead. This resulted in social disconnection, feelings of guilt, and difficulty in making sense of the death and reconstructing relationships. In response to this context a theoretically informed, co-produced web-resource to facilitate meaning-making, which situates bereavement in the context of family and friends, was developed. This paper describes the development of the web-based intervention. Study aims To co-produce a web-based intervention theoretically informed by the family level extension Dual Process Model and Family Sense of Coherence, and pilot the intervention gaining user feedback to inform refinements in readiness for adoption and implementation. Methods Following a scoping review, a mixed methods study was undertaken using an online survey via questionnaire and virtual co-production workshop with bereaved people and bereavement professionals. Results Survey respondents (n=32) reported the pandemic negatively affected bereavement (guilt, isolation, inability to bear witness) but also presented new opportunities to celebrate the deceased and support the bereaved (new funeral rituals, technology, remote contact, social acknowledgement of grief). Sense-making and managing bereavement were helped through information-giving, support networks, and relocating the person within the family context. A web-resource to facilitate collective grief was viewed positively and endorsed. Key content including family activities to stimulate support, information regarding the range of grief experience and dealing with the practicalities, along with other sources of support was agreed by workshop participants (n=5) to form the basis of the intervention. Conclusion The publicly accessible Families and Friends in Bereavement intervention encourages consideration of bereavement in the context of close social networks. It enables grief to be understood and managed within a shared experience by promoting communication and meaning-making.

Background The enhanced green fluorescent protein (EGFP) gene is a reporter gene that can be used to optimize protein isolation procedures and the functional working of a transduction protein. EGFP, with the addition of eleven arginine residues, has been engineered to functionally improve the protein transduction process, which can later be used for cell reprogramming like induced pluripotent stem cells. The addition of six histidine amino acid residues at its C-terminal is intended for the protein isolation process using the His-tag antibody. Methods The study aimed to investigate the optimization of the EGFP polyarginine protein expression in Saccharomyces cerevisiae in sufficient quantities for the protein isolation stage. This study also analyzed EGFP expression without polyarginine to analyze the polyarginine addition effect on expression processes. Protein expression was qualitatively measured by looking at expression fluorescence and protein levels of EGFP and EGFP - PolyR proteins. Results The addition of a PolyR group to the C-terminal of EGFP carrying C-terminal 6×His-tag showed similar fluorescence expression levels compare to EGFP without addition of PolyR as well. Moreover, yeast with plasmid insertion showed decrease S. cerevisiae growth curve but still preserving the fluorescence EGFP. Conclusions The expression of the EGFP modified protein in S. cerevisiae is not affected by the addition of arginine.

Background Active participation of stroke survivors during robot-assisted movement therapy is essential for sensorimotor recovery. Robot-assisted therapy contingent on movement intention is an effective way to encourage patients’ active engagement. For severely impaired stroke patients with no residual movements, a surface electromyogram (EMG) has been shown to be a viable option for detecting movement intention. Although numerous algorithms for EMG detection exist, the detector with the highest accuracy and lowest latency for low signal-to-noise ratio (SNR) remains unknown. Methods This study, therefore, investigates the performance of 13 existing EMG detection algorithms on simulated low SNR (0dB and -3dB) EMG signals generated using three different EMG signal models: Gaussian, Laplacian, and biophysical model. The detector performance was quantified using the false positive rate (FPR), false negative rate (FNR), and detection latency. Any detector that consistently showed FPR and FNR of no more than 20%, and latency of no more than 50ms, was considered an appropriate detector for use in robot-assisted therapy. Results The results indicate that the Modified Hodges detector – a simplified version of the threshold-based Hodges detector introduced in the current study – was the most consistent detector across the different signal models and SNRs. It consistently performed for ~90% and ~40% of the tested trials for 0dB and -3dB SNR, respectively. The two statistical detectors (Gaussian and Laplacian Approximate Generalized Likelihood Ratio) and the Fuzzy Entropy detectors have a slightly lower performance than Modified Hodges. Conclusions Overall, the Modified Hodges, Gaussian and Laplacian Approximate Generalized Likelihood Ratio, and the Fuzzy Entropy detectors were identified as the potential candidates that warrant further investigation with real surface EMG data since they had consistent detection performance on low SNR EMG data.

Background: Customer churn prediction (CCP) refers to detecting which customers are likely to cancel the services provided by a service provider, for example, internet services. The class imbalance problem (CIP) in machine learning occurs when there is a huge difference in the samples of the positive class compared to the negative class. It is one of the major obstacles in CCP as it deteriorates performance in the classification process. Utilizing data sampling techniques (DSTs) helps to resolve the CIP to some extent. Methods: In this paper, we review the effect of using DSTs on algorithmic fairness, i.e., to investigate whether the results pose any discrimination between male and female groups and compare the results before and after using DSTs. Three real-world datasets with unequal balancing rates were prepared and four ubiquitous DSTs were applied to them. Six popular classification techniques were utilized in the classification process. Both classifier’s performance and algorithmic fairness are evaluated with notable metrics. Results: The results indicated that the Random Forest classifier outperforms other classifiers in all three datasets and, that using SMOTE and ADASYN techniques causes more discrimination in the female group. The rate of unintentional discrimination seems to be higher in the original data of extremely unbalanced datasets under the following classifiers: Logistics Regression, LightGBM, and XGBoost. Conclusions: Algorithmic fairness has become a broadly studied area in recent years, yet there is very little systematic study on the effect of using DSTs on algorithmic fairness. This study presents important findings to further the use of algorithmic fairness in CCP research.

Background: Bioclimatic design is an approach based on local climate which improves thermal qualities and indoor comfort. Buildings follow this process to minimize negative effects on the environment. However, this approach is still not suitable in developed countries. This study aims to investigate Mediterranean local bioclimatic strategies’ impact on thermal comfort efficiency in housing, by examining architectural elements and treatments. Methods: We adopted a descriptive, analytical, and comparative methodology, complemented with a software simulation, within a qualitative and quantitative approach. Investigation and methodological tools were based on technical information including plans, elevations, photos, and documentation. The approach consisted of multiple stages: a literature review interpreting the concept of bioclimatic design, as well as thermal comfort variables and common Mediterranean building features. Moreover, the paper showcases three examples of successful Mediterranean passive houses. Furthermore, the paper presents a case- studyhouse in Alex West, Alexandria, designed in the Mediterranean Revival style. Results: The results showed that the most influencing building features on thermal comfort were the low-pitched roofs and the top chimney, which achieved 12.6% and 5% improvement in the summer and 13% and 6.8% in winter, respectively. The pergola and porch elements barely had an effect when placed on the northern façade. However, on the southern façade, a positive contribution in the summer by 1.4% and 3.4% respectively were reported, but a slight negative impact in winter by 0.5% and 2% respectively. Conclusions : We examined the impact of common Mediterranean building features , and compared thermal comfort results between case-study houses. Features focusing on passive design for cooling rather than heating, allowing wind flow for maximized natural ventilation, using ventilated pitched roof spaces, using sun shading elements in the proper facades and angles, help passive thermal regulation. The study proposes recommendations for optimizing thermal comfort in residential buildings in Alexandria, Egypt.

Background (Pop/Rock is experiencing deep transformations caused by the emergence of Web 2.0 and the online social networks, streaming services and the proliferation of TV contests. Cover songs afford the opportunity to explore how these changes would result in a new revalorization of Pop and Dance music. The aim of this paper is to find evidence of a changing pattern in cover songs by 21st-century artists. To this end, over 76,000 covers performed by artists who grew up in the 2000s were quantitatively analyzed. Methods SecondHandSongs.com was crawled to extract the cover relationships, and Allmusic.com to obtain the genre and starting decade of each performer. Results The results show that the current music panorama is dominated by Pop/Rock music and, for the first time since the 1960s, artists from the 2010s generation prefer to cover more songs by contemporary artists than by classic figures from the 1960s. Pop and Dance are the emerging sub-genres with the largest proportion of covered musicians, while Taylor Swift, Justin Bieber and Ed Sheeran are responsible for this changing trend. Conclusions These results provide an interesting opportunity to introduce quantitative studies in cultural studies about music, cinema and arts.

Background As part of the transition of every higher education institution into an intelligent campus here in the Philippines, the Commission of Higher Education has launched a program for the development of smart campuses for state universities and colleges to improve operational efficiency in the country. With regards to the commitment of Camarines Sur Polytechnic Colleges to improve the accreditation operation and to resolve the evident problems in the accreditation process, the researchers propose this study as part of an Integrated Quality Assurance System that aims to develop an intelligent model that will be used in categorizing and automating tagging of archived documents used during accreditation. Methods As a guide in modeling the study, the researchers use an agile method as it promotes flexibility, speed, and, most importantly, continuous improvement in developing, testing, documenting, and even after delivery of the software. This method helped the researchers design the prototype with the implementation of the said model to aid the file searching process and label tagging. Moreover, a computational analysis is also included to understand the result from the devised model further. Results As a result, from the processed sample corpus, the document labels are faculty, activities, library, research, and materials. The labels generated are based on the total relative frequencies, which are 0.009884, 0.008825, 0.007413, 0.007413, and 0.006354, respectively, that have been computed between the ratio of how many times the term was used in the document and the total word count of the whole document. Conclusions The devised model and prototype support the organization in file storing and categorization of accreditation documents. Through this, retrieving and classifying the data is easier, which is the main problem for the task group. Further, other clustering, modeling, and text classification patterns can be integrated into the prototype.

Background The COVID-19 pandemic has increased the need for mask production which has caused the problem of mask waste generating in the environment without being managed. This research was conducted to determine the relationship between knowledge, attitudes, and sociodemographic factors with college student behaviours in managing household mask waste in Daerah Khusus Ibukota (DKI) Jakarta Province. Methods This study used a quantitative approach and cross-sectional study design. Data collection was carried out using an online questionnaire consisting of the respondents’ sociodemographic, knowledge, attitudes, and behaviours. Results The majority of students had high knowledge (63.3%), positive attitudes (52.5%), and good behaviours (50.6%). Statistically, there was a significant relationship between knowledge and behaviours (p = 0.022), but there was no significant relationship between attitudes and behaviours (p = 0.269). In addition, the sociodemographic factor variables showed a significant relationship between place of residence and behaviours (p = 0.008). However, there was no significant relationship between age, gender, education, and study program groups and behaviours (p > 0.05). Multivariate analysis showed that living with family was a dominant factor for bad behaviours (OR 1.664, 95% CI=1.124-2.464), and the second risk factor was the low level of knowledge has a significant relationship with the behaviours of mask waste management at home (OR=1.559, 95% CI=1.044-2.330). Conclusions Students who live alone also show better behaviour compared to students who live with their families. The place of residence variable has the greatest influence on the behaviour of mask waste management at the household, followed by the knowledge variable.

Background Giant gourami ( Osphronemus goramy Lacepede, 1801) is a popular freshwater species in Indonesia, but there is limited information on feed used for its cultivation. Therefore, this study aims to determine effect of feed enriched with fermented coconut water and palm sap sugar solution on growth, feed efficiency, and carcass composition of juvenile sago gurami. Methods A total of 2 litres coconut water and 1litres palm sap sugar solution (10%) were formulated. Each formulated product was then mixed with 6 g Aspergillus niger (P1), 6 g Rhizopus oligosporus (P2), and 6 g Saccharomyces cerevisiae (P3) to obtain the supplements. Subsequently, supplementation was carried out on commercial feed at a dose of 300 ml/kg of feed. Samples supplemented with P1, P2, and P3 were designated P1, P2, and P3 diets, while feed added to freshwater was considered P4 (placebo). Gurami sago juvenile (initial weight 50±2.5 g and length 13.2±0.4 cm) were then placed in triplicate nets (2×1×1 m) in a freshwater concrete pond with a stocking density of 30 fish/net. Results The different products formulations had a significant effect (p Conclusion Based on the results, P2 contained a higher concentration of fatty acids compared to other diets, leading to increased body weight, feed efficiency, and carcass fatty acid composition in sago gurami reared in freshwater concrete ponds.

Knowledge graph (KG) publishes machine-readable representation of knowledge on the Web. Structured data in the knowledge graph is published using Resource Description Framework (RDF) where knowledge is represented as a triple (subject, predicate, object). Due to the presence of erroneous, outdated or conflicting data in the knowledge graph, the quality of facts cannot be guaranteed. Trustworthiness of facts in knowledge graph can be enhanced by the addition of metadata like the source of information, location and time of the fact occurrence. Since RDF does not support metadata for providing provenance and contextualization, an alternate method, RDF reification is employed by most of the knowledge graphs. RDF reification increases the magnitude of data as several statements are required to represent a single fact. Another limitation for applications that uses provenance data like in the medical domain and in cyber security is that not all facts in these knowledge graphs are annotated with provenance data. In this paper, we have provided an overview of prominent reification approaches together with the analysis of popular, general knowledge graphs Wikidata and YAGO4 with regard to the representation of provenance and context data. Wikidata employs qualifiers to include metadata to facts, while YAGO4 collects metadata from Wikidata qualifiers. However, facts in Wikidata and YAGO4 can be fetched without using reification to cater for applications that do not require metadata. To the best of our knowledge, this is the first paper that investigates the method and the extent of metadata covered by two prominent KGs, Wikidata and YAGO4.

Background Paediatric neuroblastoma and brain tumours account for a third of all childhood cancer-related mortality. High-risk neuroblastoma is highly aggressive and survival is poor despite intensive multi-modal therapies with significant toxicity. Novel therapies are desperately needed. The Zika virus (ZIKV) can access the nervous system and there is growing interest in employing ZIKV as a potential therapy against paediatric nervous system tumours, including neuroblastoma. Methods Here, we perform extensive data mining, integration and re-analysis of ZIKV infection datasets to highlight molecular mechanisms that may govern the oncolytic response in neuroblastoma cells. We collate infection data of multiple neuroblastoma cell lines by different ZIKV strains from a body of published literature to inform the susceptibility of neuroblastoma to the ZIKV oncolytic response. Integrating published transcriptomics, interaction proteomics, dependency factor and compound datasets we propose the involvement of multiple host systems during ZIKV infection. Results Through data mining of published literature, we observed most paediatric neuroblastoma cell lines to be highly susceptible to ZIKV infection and propose the PRVABC59 ZIKV strain to be the most promising candidate for neuroblastoma oncolytic virotherapy. ZIKV induces TNF signalling, lipid metabolism, the Unfolded Protein Response (UPR), and downregulates cell cycle and DNA replication processes. ZIKV infection is dependent on sterol regulatory element binding protein (SREBP)-regulated lipid metabolism and three protein complexes; V-ATPase, ER Membrane Protein Complex (EMC) and mammalian translocon. We propose ZIKV non-structural protein 4B (NS4B) as a likely mediator of ZIKVs interaction with IRE1-mediated UPR, lipid metabolism and mammalian translocon. Conclusions Our work provides a significant understanding of ZIKV infection in neuroblastoma cells, which will facilitate the progression of ZIKV-based oncolytic virotherapy through pre-clinical research and clinical trials.

Background:For years now, cancer treatments have entailed tried-and-true methods. Yet, oncologists and clinicians recommend a series of surgeries, chemotherapy, and radiation therapy. Yet, even amidst these treatments, the number of deaths due to cancer increases at an alarming rate. The prognosis of cancer patients is influenced by mutations, age, and various cancer stages. However, the association between these variables is unclear. Methods: The present work adopts a machine learning technique—k-nearest neighbor; for both regression and classification tasks, regression for predicting the survival time of oral cancer patients, and classification for classifying the patients into one of the predefined oral cancer stages. Two cross-validation approaches—hold-out and k-fold methods—have been used to examine the prediction results. Results: The experimental results show that the k-fold method performs better than the hold-out method, providing the least mean absolute error score of 0.015. Additionally, the model classifies patients into a valid group. Of the 429 records, 97 (out of 106), 99 (out of 119), 95 (out of 113), and 77 (out of 91) were classified to its correct label as stages – 1, 2, 3, and 4. The accuracy, recall, precision, and F-measure for each classification group obtained are 0.84, 0.85, 0.85, and 0.84. Conclusions: The study showed that aged patients with a higher number of mutations than young patients have a higher risk of short survival. Senior patients with a more significant number of mutations have an increased risk of getting into the last cancer stage

Background Houseflies are the most common type of Diptera, specifically Muscidae, worldwide, representing more than 90% of all species. This family has over 170 genera and 4200 species, but a few are of medical significance. This study aimed to estimate and assessing the measures to control and prevent grow-up inside houses and flying of the housefly ( Musca domestica Linnaeus, 1758) in Misan. Methods The study occurred over 12 months, from December 2020 to December 2021. Using plastic containers, Musca domestica were collected from all potential breeding sites in the study region (inside and around houses). Sticky oil paper and traps were used to collect the insects. The collected insects were transferred to sealed plastic containers and then to the laboratory of the Department of Microbiology. Out of 200 randomly selected houses, 150 (75%) contained insects. Light traps and sticky oil papers were the most effective control measures, with 26.7% and 25.9% of the Musca domestica collected from these methods, respectively. The ratio of male (233) to female (456) Musca was 1:2, with a significant difference between the frequencies (PMusca were collected during the cold months (188, 27.3%), with a strongly significant difference (P Conclusions Misan has a high density of Musca domestica, with females being more prominent than males. Hot climate, humid sites, and dirty places are responsible for the breeding of houseflies. The overall larval density was medium. Therefore, the risk of transmitting infectious diseases by houseflies is high within the boundaries of Misan province, and effective control parameters should include measures like light traps and sticky oil.

Background Based on singns prohibitiing certain action, people warn othersusing imperative forms of the verb or give a soft warning Based on signs prohibiting certain actions, people warn others using imperative forms of the verb or give a soft warning using politeness strategies. This study investigates actual situations in which native Japanese speakers and Uzbek learners of Japanese give warnings about prohibitions. Methods This study compared warnings given by native Japanese speakers and Uzbek Japanese learners regarding prohibited acts. After clarifying the difference between prohibition and warning of prohibitions, we proposed a classification scheme for the latter speech act in terms of politeness. Data were elicited using a discourse completion task. Results The results showed that the Japanese speakers tended to mitigate warnings by implementing two politeness strategies: expression in hedged forms and positioning the warning as a rule. The Japanese speakers used expressions such as “It is prohibited” to indicate that they warned as a rule. Such expressions may cause the hearer to feel that the speaker is an overbearing person who wields authority. To avoid this risk, the Japanese speakers used hedges, such as “Looks like it’s prohibited,” or “It says it’s prohibited,” to make it clear that the right to forbid is not with them but with the public authority. In contrast, the Uzbek learners of Japanese tended to implement their politeness strategy as an apology to compensate for the explicit warning. They tended to apologize in situations where the Japanese speakers would not. Conclusions The present study presented a framework for categorizing warning of prohibitions. This framework can be applied to languages other than Japanese, Uzbek, and Japanese by Uzbek learners.

Background Fish scale waste is highly valued both as a functional food ingredient and a potential feed source for farmed fish. This study aimed to analyse the chemical composition, fatty acid profile, and mineral content in fish scale flour of Osphronemus (O) goramy, Cyprinus (C) carpio, and Oreochromis (O) niloticus as potential feed for fish fry. Methods Fish scales were cleaned with 10% w/v NaCl solution at a ratio of 1:10 (w/w) for 24 hours at 4 °C. Agitation was used every eight hours to remove excess protein. Fish scales were evenly arranged in a cooker and cooked at 121 °C for 10 minutes with 15 psi pressure. After cooking, 100 grams of wet fish scales was dried at 50 °C for four hours. Dried fish scales were transformed into flour for proximate composition analysed via standard AOAC method, amino acid and fatty acid assessment employing HPLC and GC-MS, while mineral content was determined using AAS. Results The examined fish scale flour from three species displayed significant variations in chemical components, amino acids, and minerals (p Conclusions Flour from three farmed fish types has potential for fish fry feed due to its chemical composition, amino acid, and mineral content. Further validation is needed for amino acid comparison to fish meal.

Background: Mystacoleucus padangensis living in Lake Singkarak, Indonesia, has high potential market demand but is threatened by overfishing and has not been successfully cultured. This study describes the first broodstock development, induced breeding, and larval rearing of M. padangensis. Methods: A total of 1,000 female and 1,000 male broodfish were collected from the wild and reared in two concrete ponds (128 m 2) at the Centre for Biodiversity Conservation, P.T. Semen Padang, Indonesia. The broodfish were fed commercial feed to satiation at 09:00 and 17:00 h. The females (average weight 7.56 ± 0.85 g) and males (4.86 ± 1.20 g) were selected at a ratio of 1:4 (female:male), and gonad maturation was induced with a single dose of GnRH analogue (Ovaprim) of 0.1 ml/fish. At 16 h after hormone injection, eggs were collected individually into a plastic vessel. Spermatozoa were collected with sterile syringes. Eggs were fertilized using the 'dry' method, and 0.5 ml samples (equal to 100 eggs) were taken. The eggs were incubated in a plastic strainer with a water volume of 1.57 litres and placed in a tarpaulin pond with a volume of 150.72 litres. Results: The overall hatching rate was 78.93 ± 4.13%. The newly hatched larvae were 3900.81 µm long, with a yolk sac of 82881.480 µm 2. The mouth opened at 72 days post hatching (DPH) with a gape measuring approximately 61.880 µm. The protocol of larval feeding started with artificial feed, followed by Artemia nauplii up to 30 DPH. Weaning of larvae started at 4 DPH. Larvae started metamorphosis by 15 DPH and ended by 22 DPH when the larvae reached 7430.27 µm. Larval rearing resulted in an average survival rate of 28.4 ± 3.04%. Conclusions: Its successful spawning induction and high larval hatching and survival rates make M. padangensis an excellent aquaculture candidate.

Background: Since the emergence of HIV and the AIDS pandemic, the majority of risk-reduction interventions have been centred on the use of condoms in sex workers. Methods: This qualitative study recruited 25 male migrant sex workers in London to understand their risk perception and condomless sex experiences within the context of sex work and private life. The data was collected using face-to-face interviews, analysed using thematic analysis, and the findings interpreted through the theory of planned behaviour. Results: The themes explain that condomless sex with clients occurred when participants consciously accepted to perform this service deploying a risk assessment of clients, faulty strategies, and sexual practices to reduce their risk; or when they lost control because of recreational drugs, feeling attraction to clients, were in precarious circumstances, or were victims of violence. Conversely, condomless sex with non-commercial partners occurred according to the type of relationship, with formal partners it was rationalised through emotional aspects attached to this kind of relationship, while with casual partners it was connected to sexual arousal and the use of alcohol and drugs. Conclusions: Reinforce educational interventions to deliver STI-HIV information, enhance the use of condoms, and to address specific contextual factors that facilitate condomless practice with commercial and non-commercial sexual partners.

Background: Open science is a movement and set of practices to conduct research more transparently. The adoption of open science has been recognized to support innovation, equity, and transparency. The Montreal Neurological Institute-Hospital (Neuro) has committed to becoming an ‘open science’ institute, the first of its kind in Canada. Here we report on an audit of open data practices in Neuro publications and on a survey of Neuro-based researchers’ barriers and facilitators to data sharing. Methods: In the first study, we retrieved 313 unique publications and collated all Neuro publications from 2019 and extracted information from each article pertaining to data sharing and other open science practices. We included all empirical papers and pre-prints that were reported in English. In the second study, one hundred twenty-four participants (out of 553) completed the survey, with a response rate of 22.42%. We surveyed all Neuro researchers. For the audit, we examined data sharing and open science practices. For the survey, we asked participants questions about their data sharing practices and perceptions. Results: We found that 66.5% of these publications (n=208) included a data sharing statement. Overall, 74.5% (n=155) of articles had data that was publicly available. When examining broader open science practices, rates of compliance tended to be lower. For example, 94.9% (n=297) of publications failed to register a protocol. Among participants who had published a first or last authored paper in the past year, most participants, 53 of 74 (71.62%), reported that they had openly shared their research data. Less than half of the participants, 37.50% (n=45), reported having engaged in training related to data sharing within the last 12 months. Conclusion: We found that half of all publications included in the audit shared data. Participants indicated an appetite for resources for learning about data-sharing signaling a willingness to perform better.

Background: One of the primary drivers in development of novel quantum-safe cryptography techniques is the ongoing National Institute of Standards and Technology (NIST) Post-Quantum Cryptography (PQC) competition, which aims to identify quantum-safe algorithms for standardization. Although NIST has recently announced candidates to be standardized, the development of novel PQC algorithms remains desirable to address the challenges of quantum computing. Furthermore, to enhance security and improve performance. Methods: This paper introduces a novel public key encapsulation algorithm that incorporates an additional layer of encryption during key construction procedure, through a hidden ring. This encryption involves modular multiplication over the hidden ring using a homomorphism operator that is closed under addition and scalar multiplication. The homomorphic encryption key is comprised of two values - one used to create the hidden ring and the other to form an encryption operator. This homomorphic encryption can be applied to any polynomials during key construction over a finite field with their coefficients considered private. Particularly, the proposed homomorphic encryption operator can be applied to the public key of the Multivariate Public Key Cryptography schemes (MPKC) to hide the structure of its central map construction. Results: This paper presents a new variant of the MPKC with its public key encrypted using the proposed homomorphic operator. This novel scheme is called the Homomorphic Polynomial Public Key (HPPK) algorithm, which simplifies MPKC central map to two multivariate polynomials constructed from polynomial multiplications. The HPPK algorithm employs a single polynomial vector for the plaintext and a multi-variate noise vector associated with the central map. In contrast, in MPKC, a single multivariate vector is created by segmenting the secret plaintext over a small finite field. The HPPK algorithm is Indistinguishability Under Chosen-Plaintext Attack (IND-CPA) secure, and its classical complexity for cracking is exponential in the size of the prime field GF(p).

Background: In this paper, we focus on an efficient and easy method for solving the given system of differential-algebraic equations (DAEs) of second order. Methods: The approximate solutions are computed rapidly and efficiently with the help of a semi-analytical method known as Adomian decomposition method (ADM). The logic of this method is simple and straightforward to understand. Results: To demonstrate the proposed method, we presented several examples and the computations are compared with the exact solutions to show the efficient. One can employ this logic to different mathematical software tools such as Maple, SCILab, Mathematica, NCAlgebra, Matlab etc. for the problems in real life applications. Conclusions: In this paper, we offered a method for solving the given system of secondorder nonlinear DAEs with aid of the ADM. We shown that the proposed method is simple and efficient, also one can obtain the approximate solutions quickly using this method. A couple of examples are discussed for illustrating this method and graphical and mathematical assessments are discussed with the analytical solutions of the given problems.

Research output provides an insight into the development of the scientific capability of a country. Budget allocation for research and development (R&D) is directly proportional to the research output of a country. Bibliometric analysis of South American countries has not been done in many studies. The purpose of this paper was to analyse research outputs from South American countries on various metrics. An analysis was done for a period of 11 years from 2010 to 2020. The analysis revealed that Brazil with highest percentage of research spend has lowest Field Weighted Citation Impact (FWCI). This contrasts with Uruguay, whose FWCI is high despite comparatively lower spend on R&D and lower publication output. Although Argentina has the highest percentage of researchers per million population (1202), it has the least papers per researchers (0.3 per year) among the countries studied. A huge disparity in terms of percentage of research spent, research output, papers per researcher, and output with national and international co-authorship was observed.

Background: Two-wheeled vehicles are the major mode of transportation in India. Such vehicles are exposed to excessive vibration on the road when compared to four-wheeled vehicles. However, the research on the reduction of whole body vibration in the case of two-wheelers is not explored in detail. The present study predicts rider comfort in the case of an electric two-wheeler as per ISO 2631-1. Methods: An electric two-wheeler test rig is used in the study. The values of acceleration from the test rig in running conditions are obtained by using NI LabVIEW 2016. The drive cycle of the electric vehicle (EV) test rig is controlled by Sync sols’ EV lab software. Obtaining the root mean square (RMS) acceleration from running the test setup, it is compared with the ISO 2631 standard to obtain the rider comfort. Results: Loading area, traction motor, base mount, and suspension were found to be the strategic points of vibration. RMS acceleration of 0.2 g to 3.29 g obtained at these points are prone to cause discomfort for the rider. Vehicle speed, road profile, and duration of exposure were found to be important parameters affecting the rider’s comfort. A maximum of 3.28 g amplitude was observed at the loading area at no load condition. The loading area, which corresponds to a rider’s seat in actual vehicle, is important and reduction of these vibrations make the ride comfortable for the rider. Suspension and base mount of the test rig are found to be uncomfortable observing the RMS acceleration. Conclusions: A suitable damping technique design is very much essential in reducing these vibrations and improve the rider comfort, as many more non-deterministic vibrations are prone to cause dis-comfort in case of actual on road riding conditions.

Background: The aim of this paper was to explore how the Fourth Industrial Revolution shapes teaching and learning during COVID-19 in some of the schools located in the Gauteng and Mpumalanga provinces, South Africa. This paper employed qualitative interpretative multiple case study design. Purposive sampling was used to sample our participants. Methods: We selected four teachers who separately taught at the early childhood development stage, intermediate phase, senior phase, and further education and training phases. Data was collected telephonically through semi-structured interviews with teachers from Limpopo, Gauteng and Mpumalanga provinces of South Africa. Data was collected from their experiences of COVID-19 from 2019 to 2021. Collected data was analysed using a typology approach whereby themes that derived from the literature reviewed and research questions were used. Results: We inferred from the results of the paper that teachers had challenges with teaching and availability of learning resources, such as limited access to internet and socio-economic backgrounds, which hindered the integration of the Fourth Industrial Revolution in the teaching and learning process. There were also challenges related to teachers’ background on the usage of the Fourth Industrial Revolution and the lack of school management teams support. The paper revealed that the integration of the Fourth Industrial Revolution in teaching and learning was affected negatively by the existence of the above-mentioned challenges, which needs to be addressed. Conclusions: Therefore, we recommended that the government and stakeholders within the education sector provide resources such as smart-boards, computers, and network access in schools lacking such facilities, as well as providing professional development interventions and training teachers to have an in-depth understanding of the Fourth Industrial Revolution within the teaching and learning context.

Background: The study examines the gaps in the provisions of the Petroleum Industry Act (PIA) that could hinder the effective application of the Act in attaining its objectives. The repealed Petroleum Act of 1969 became obsolete and largely incapable of meeting the emerging global best practices in the industry due to inadequate sanctions, failure to address the aspirations of the people of the oil-bearing states, among others. Hence, the need for the PIA of 2021 to overhaul the industry to meet global standards though some controversial provisions that pose challenges to its proper implementation. Methods: The study examines the PIA to identify its prospects, challenges, and the way forward. The methodology the study utilises is doctrinal research with reports from existing literature and tertiary data sources such as newspapers, the Internet, and websites. Pertinent data collected from these sources were theoretically analysed and argued with current literature on the subject. Results: The finding is that the PIA does not make adequate provisions for the energy transition in line with Nigeria’s Nationally Determined Contributions (NDC) under the Paris agreement; the PIA was provided for weak institutions, which translates to weak implementation and enforcement of the law which further widening the gap between the law and reality. Conclusions: The study concluded that, although the Act delivered the much-needed stability in the petroleum industry in Nigeria, there is a need for an overhaul of the Act to further protect the interest of host communities and allow for co-ownership of petroleum resources by the state government.

Background: This article examines how current jurists can deal with a juristic division of the world into abode of “Islam” and “infidelity”. The success with which jurists re-evaluate this dichotomy will have major impacts on how an Islamic state interacts with non-Muslim governments on the one hand, and Muslims residing temporarily or permanently in a non-Muslim territory on the other. Methods: Here, an attempt made to review the concepts of Dar Al-Islam and Dar Al-Harb from two perspectives: that of the dialectical limits and liberalization, as discussed in secondary material such as books, research articles, and reports. Results: this paper has explored and discussed the criteria for identifying Dar Al-Islam and Dar Al-Harb in Islamic jurisprudence. Conclusions: This article analyzes the various arguments put forward to establish new ways of peaceful coexisting and maintaining healthy international connections.

Background: Dengue fever is still a public health issue in Indonesia, and during the coronavirus disease 2019 (COVID-19) pandemic, integrated digital technology will be required for its control. This study aims to identify critical indicators influencing attitudes towards dengue control related to the potential for implementing digital technology. Methods: This was a cross-sectional survey, with 515 people willing to fill out an online questionnaire. The analysis was conducted using Partial Least Square-Structural Equation Modelling (PLS-SEM). There were 46 indicators used to assess attitudes toward dengue control, which were organized into six variables: the need for digital information systems, perceptions of being threatened with dengue, the benefits of dengue control programs, program constraints, environmental factors and attitudes in dengue control. Results: The source of information needed for dengue control was mainly through social media. There was a positive relationship between perception of environmental factors to perception of dengue threat, perception of program constraints, perception of program benefits, and perception of digital technology needs. Perception of program benefits and threatened perception of dengue have a positive relationship with perception of digital technology needs. Conclusions: This model showed the variables perception of digital technology and perception of benefits had a positive association with attitude towards dengue control

Background: This paper offers a thematic interpretation of patterns of employee-centric discussions (ECD) in chairman speeches during the period of 2004-2008 and 2010-2014 wherein the former is considered the pre-recession period and the latter the post-recession period. A situation like recession calls for focus on employee relations and development. In the economic context of recession, the paper suggests that the attitudinal approach of top echelons towards employees can in part be explained by the themes of ECDs through the comparative analysis of pre- and post-recession periods. Methods: This paper adopts a qualitative content analysis approach to study the themes of ECDs present in the chairman’s speech, in the view of two economic contexts i.e., pre- and post-recession. Companies were identified from the CNX 2016 Nifty 50-stock index, then chairman’s statements were downloaded using each company’s official website which met the inclusion criteria. Data collection was from November 2020-March 2021. Thematic analysis was conducted using Atlas.ti, all ECD excerpts were extracted from the speeches based on the referring terms used for employees. Keywords were identified using Atlas.ti software. Preliminary coding of the ECD excerpts was carried out at the sentence level adopting the summative approach. Tagged codes were then used as keywords to extract excerpts concerning employees which did not have referring terms in it. Results: The finding suggests that the ECDS have four dominant themes - acknowledgment and appreciation, confidence, employee relations, and employee value. It also indicates an increase in ECDs in the post-recession period.
