1. Data-Driven Decision-Making: Leveraging the IoT for Real-Time Sustainability in Organizational Behavior.

Author

Malik, Saadia

Abstract

In today's business environments, data-driven decision-making has played a crucial role in bringing real-time sustainability to organizational behavior. Furthermore, the Internet of Things (IoT) has been widely adopted recently, but studies investigating its impact on organizational dynamics and sustainability are limited. This study explores the IoT's potential to improve the real-time decision-making and sustainability of organizations. A cross-sectional study was conducted on 250 respondents belonging to a diverse range of industries. Five variables were analyzed in the study—IoT implementation, real-time data analytics, decision-making, organizational behavior, and organizational performance. These variables were scored on a 5-point Likert-type scale, with responses ranging from 1 = Strongly Disagree to 5 = Strongly Agree. The data were collected with the help of a structured questionnaire. The data were analyzed using descriptive statistics, Pearson correlations, and structural equation modeling (SEM) to test the relationships among the study variables. The findings indicate that enhanced organizational behavior (r = 0.1101), decision-making (r = 0.269), and real-time data analytics (r = 0.1888) are all strongly associated with the IoT. Applying structural equation modeling further reveals a direct connection between IoT adoption and company performance. Moreover, it is observed that the coefficients for organizational behavior (β = 0.0707, p < 0.01) and real-time data analytics (β = 0.0851, p < 0.001) are statistically significant. This study demonstrates how the IoT can bring real-time sustainability to organizational behavior by improving decision-making and business operations. Although decision-making is enhanced by the IoT, organizations still need to optimize their resource usage and reduce waste to enhance sustainability. This study bridges a substantial gap in the existing literature by carefully investigating the relationship between IoT technology, organizational behavior, and decision-making techniques. Our findings conclude that leveraging the IoT changes the nature of digital innovation and brings real-time sustainability to organizational behavior. [ABSTRACT FROM AUTHOR]

Abstract

The current investigation examines the numerical performance of the fractional-order endemic disease model based on the direct spreading of cholera by applying the neuro-computing Bayesian regularization (BR) neural network process. The purpose is to present the numerical solutions of the fractional-order model, which provides more precise solutions as compared to the integer-order one. Real values based on the parameters can be obtained and one can achieve better results by utilizing these values. The mathematical form of the fractional direct spreading cholera disease is categorized as susceptible, infected, treatment, and recovered, which represents a nonlinear model. The construction of the dataset is performed through the implicit Runge–Kutta method, which is used to lessen the mean square error by taking 74% of the data for training, while 8% is used for both validation and testing. Twenty-two neurons and the log-sigmoid fitness function in the hidden layer are used in the stochastic neural network process. The optimization of BR is performed in order to solve the direct spreading cholera disease problem. The accuracy of the stochastic process is authenticated through the valuation of the outputs, whereas the negligible calculated absolute error values demonstrate the approach's correctness. Furthermore, the statistical operator performance establishes the reliability of the proposed scheme. [ABSTRACT FROM AUTHOR]

Abstract

This article reflects the perspectives of journalism educators responsible for preparing journalists for careers in the Middle East and North Africa region, which has received little attention in trauma education research. A survey with quantitative and qualitative questions is used to reflect opinions of 101 journalism educators from Algeria, Sudan, and Palestine on journalism trauma-focused education and to elicit their attitudes toward incorporating trauma education into their institutions' journalism curricula. The findings revealed that journalism educators are particularly cognizant of the role of trauma in journalism practice and the relevance of incorporating trauma education elements into journalism curricula. Journalism educators have identified a number of barriers to incorporating trauma into their institutions' journalism curricula, as well as various perspectives on how to incorporate trauma-focused education into journalism curricula, which could call for changing how journalism is taught in their respective institutions. The study establishes a methodological foundation for other scholars to use when investigating triangulation (or the lack thereof) among educators, students, and practitioners in their own communities.

Abstract

Bioinformatics education has been a hot topic in South Asia, and the interest in this education peaks with the start of the 21st century. The governments of South Asian countries had a systematic effort for bioinformatics. They developed the infrastructures to provide maximum facility to the scientific community to gain maximum output in this field. This article renders bioinformatics, measures, and its importance of implementation in South Asia with proper ways of improving bioinformatics education flaws. It also addresses the problems faced in South Asia and proposes some recommendations regarding bioinformatics education. The information regarding bioinformatics education and institutes was collected from different existing research papers, databases, and surveys. The information was then confirmed by visiting each institution’s website, while problems and solutions displayed in the article are mostly in line with South Asian bioinformatics conferences and institutions’ objectives. Among South Asian countries, India and Pakistan have developed infrastructure and education regarding bioinformatics rapidly as compared to other countries, whereas Bangladesh, Sri Lanka, and Nepal are still in a progressing phase in this field. To advance in a different sector, the bioinformatics industry has to be revolutionized, and it will contribute to strengthening the pharmaceutical, agricultural, and molecular sectors in South Asia. To advance in bioinformatics, universities’ infrastructure needs to be on a par with the current international standards, which will produce well-trained professionals with skills in multiple fields like biotechnology, mathematics, statistics, and computer science. The bioinformatics industry has revolutionized and strengthened the pharmaceutical, agricultural, and molecular sectors in South Asia, and it will serve as the standard of education increases in the South Asian countries. A framework for developing a centralized database is suggested after the literature review to collect and store the information on the current status of South Asian bioinformatics education. This will be named as the South Asian Bioinformatics Education Database (SABE). This will provide comprehensive information regarding the bioinformatics in South Asian countries by the country name, the experts of this field, and the university name to explore the top-ranked outputs relevant to queries.

Abstract

BACKGROUND & OBJECTIVE: Nonverbal communication has been overlooked in medical education. The purpose of this study was to explore student-teacher perceptions regarding impact of nonverbal behavior of medical educators on educational environment. METHODOLOGY: A qualitative exploratory study was conducted among purposively chosen final year students (n=150) and medical teachers (n=73) from three dental colleges of Islamabad. A webbased survey concerning three domains of kinesics (Facial expressions, Gestures, Head movement and postures) was developed and validated before execution. Comparison of participant's responses to closed-ended questions was done by applying Fisher's Exact Test and open-ended questions were thematically analyzed. RESULTS: Response rate of students and teachers was 46% and 63% respectively. Five out of nine closed-ended questions gave statistically significant difference among student's and teacher's responses (p≤0.05). Twenty-seven sub themes emerged from three domains of kinesics. Students revealed that happy mood of their teachers reduces boredom in the classroom and a teacher's smile lets them freely express anything, whereas anger produces fear among them. According to the educators a happy instructor inspires students to study and makes the environment friendly and an undemanding smile helps build a rapport with students. Moreover, positive gestures used by teachers encourage students to clarify concepts and upright posture brings energy and motivation to the classroom. CONCLUSION: A teacher's nonverbal behavior has a profound effect on educational environment. A smile on a teacher's face creates a friendly and fearless environment whereas anger creates barriers to communication. A happy teacher can generate a pleasant and motivating learning environment.

Abstract

The vertical search engine searches in the text of specific domain. In this project, we built a pharmaceutical vertical search engine using a supervised learning classifier, Rocchio, to classify documents into two different classes; one pharmaceutical and another computer science. For learning of the classifier, small document collection is created. It is evaluated using abstracts from 86 research papers and accuracy yields 90% results. An inverted index is built containing terms from selected pharmaceutical documents. An interface is also developed to interact with the user. User can issue simple keyword like queries and documents are retrieved using TF-IDF statistics and BM25 weighting scheme. Retrieved results are ranked in descending order from the highest relevance score to lowest relevance score. New information can be classified and added to the index using search interface. The system is designed and developed using the Spiral Model and implemented in dot.net tools. The survey and interviewing techniques are also used to identify the needs and prioritizing tasks.

Abstract

Background: Foot surgery is common in patients with RA but research into surgical outcomes is limited and conceptually flawed as current outcome measures lack face validity: to date no one has asked patients what is important to them. This study aimed to determine which factors are important to patients when evaluating the success of foot surgery in RA Methods: Semi structured interviews of RA patients who had undergone foot surgery were conducted and transcribed verbatim. Thematic analysis of interviews was conducted to explore issues that were important to patients. Results: 11 RA patients (9 ♂, mean age 59, dis dur = 22yrs, mean of 3 yrs post op) with mixed experiences of foot surgery were interviewed. Patients interpreted outcome in respect to a multitude of factors, frequently positive change in one aspect contrasted with negative opinions about another. Overall, four major themes emerged. Function: Functional ability & participation in valued activities were very important to patients. Walking ability was a key concern but patients interpreted levels of activity in light of other aspects of their disease, reflecting on change in functional ability more than overall level. Positive feelings of improved mobility were often moderated by negative self perception ("I mean, I still walk like a waddling duck”). Appearance: Appearance was important to almost all patients but perhaps the most complex theme of all. Physical appearance, foot shape, and footwear were closely interlinked, yet patients saw these as distinct separate concepts. Patients need to legitimize these feelings was clear and they frequently entered into a defensive repertoire ("it's not cosmetic surgery; it's something that's more important than that, you know?”). Clinician opinion: Surgeons' post operative evaluation of the procedure was very influential. The impact of this appraisal continued to affect patients' lasting impression irrespective of how the outcome compared to their initial goals ("when he'd done it ... he said that hasn't worked as good as he'd wanted to ... but the pain has gone”). Pain: Whilst pain was important to almost all patients, it appeared to be less important than the other themes. Pain was predominately raised when it influenced other themes, such as function; many still felt the need to legitimize their foot pain in order for health professionals to take it seriously ("in the end I went to my GP because it had happened a few times and I went to an orthopaedic surgeon who was quite dismissive of it, it was like what are you complaining about”). Conclusions: Patients interpret the outcome of foot surgery using a multitude of interrelated factors, particularly functional ability, appearance and surgeons' appraisal of the procedure. While pain was often noted, this appeared less important than other factors in the overall outcome of the surgery. Future research into foot surgery should incorporate the complexity of how patients determine their outcome Disclosure statement: All authors have declared no conflicts of interest

Abstract

Background: Thoracic aortic aneurysms (TAA) and dissections are not uncommon causes of sudden death in young adults. Loeys-Dietz syndrome (LDS) is a rare, recently described, autosomal dominant, connective tissue disease characterized by aggressive arterial aneurysms, resulting from mutations in the transforming growth factor beta (TGFβ) receptor genes TGFBR1 and TGFBR2. Mean age at death is 26.1 years, most often due to aortic dissection. We report an unusually late presentation of LDS, diagnosed following elective surgery in a female with a long history of joint hypermobility. Methods: A 51-year-old Caucasian lady complained of chest pain and headache following a dural leak from spinal anaesthesia for an elective ankle arthroscopy. CT scan and echocardiography demonstrated a dilated aortic root and significant aortic regurgitation. MRA demonstrated aortic tortuosity, an infrarenal aortic aneurysm and aneurysms in the left renal and right internal mammary arteries. She underwent aortic root repair and aortic valve replacement. She had a background of long-standing joint pains secondary to hypermobility, easy bruising, unusual fracture susceptibility and mild bronchiectasis. She had one healthy child age 32, after which she suffered a uterine prolapse. Examination revealed mild Marfanoid features. Uvula, skin and ophthalmological examination was normal. Results: Fibrillin-1 testing for Marfan syndrome (MFS) was negative. Detection of a c.1270G > C (p.Gly424Arg) TGFBR2 mutation confirmed the diagnosis of LDS. Losartan was started for vascular protection. Conclusions: LDS is a severe inherited vasculopathy that usually presents in childhood. It is characterized by aortic root dilatation and ascending aneurysms. There is a higher risk of aortic dissection compared with MFS. Clinical features overlap with MFS and Ehlers Danlos syndrome Type IV, but differentiating dysmorphogenic features include ocular hypertelorism, bifid uvula and cleft palate. Echocardiography and MRA or CT scanning from head to pelvis is recommended to establish the extent of vascular involvement. Management involves early surgical intervention, including early valve-sparing aortic root replacement, genetic counselling and close monitoring in pregnancy. Despite being caused by loss of function mutations in either TGFβ receptor, paradoxical activation of TGFβ signalling is seen, suggesting that TGFβ antagonism may confer disease modifying effects similar to those observed in MFS. TGFβ antagonism can be achieved with angiotensin antagonists, such as Losartan, which is able to delay aortic aneurysm development in preclinical models and in patients with MFS. Our case emphasizes the importance of timely recognition of vasculopathy syndromes in patients with hypermobility and the need for early surgical intervention. It also highlights their heterogeneity and the potential for late presentation. Disclosures: The authors have declared no conflicts of interest

Abstract

Objective: To assess the expression of Cyclin D1 in Mucoepidermoid Carcinoma (MEC) and its association with various histological grades. Study Design: Case series. Place and Duration of Study: AFIP Rawalpindi, from Nov 2017 to Apr 2018. Material and Methods: A total of 30 cases of MEC were included in this study. Paraffin embedded blocks of patients of both genders, diagnosed with salivary gland mucoepidermoid carcinoma were included as experimental samples while necrotic, scarce and autolysed cases were not included. Tumor was graded as per the grading criteria of Auclair et al. Cyclin D1 was applied and the results were analyzed using chi-square test. Results: Of the 30 selected cases, 21 (70%) were male and 9 (30%) were female patients. According to histological grades, 14 (46.67%) comprised of low grade, 06 (20%) intermediate grade and 10 (33.34%) high grade tumors. Among these cases 6 (20%) were positive and 24 (80%) had altered results. In low grade MEC all 14 (0%) cases had negative results and none was positive. Among the 6 intermediate grade cases 3 (50%) showed positive and 3 (50%) showed altered expression and in high grade tumors 7 (70%) out of 10 had altered results and 3 (30%) showed positive results. A significant association (p-value=0.02) was seen between expression of Cyclin D1 and grades of MEC. Conclusion: A significant association was seen between Cyclin D1 expression and grades of MEC (p=0.02). Cyclin d1 showed an increase in expression with increase in grade of tumor. Hence it can serve as a potential marker for grading of mucoepidermoid carcinoma. [ABSTRACT FROM AUTHOR]

45. The Korean Wave (Hallyu) and Its Cultural Translation by Fans in Qatar.

MALIK, SAADIA IZZELDIN

Abstract

This study employs in-depth qualitative interviews with Arab fans of Korean popular culture who live in Qatar to examine their cultural translation of Korean TV drama and K-pop music. It uses a transcultural approach to fandom studies, rather than foregrounding nationality as an analytic category. It focuses on fans’ appropriations of these cultural texts in relation to their affinities, feelings, emotions, and accumulations of cultural capital used to negotiate their consumption of Korean popular culture. This article identifies emotions of frustration and fascination as central to these fans’ transnational media engagement. It thereby shows that affinity is a central concern for research on transcultural receptions of non-Western cultures by non-Western audiences. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, we describe two new approaches for processing INEX queries. For CO queries, we adopt Amati’s divergence from randomness approach (aka language model) and extend it by an additional factor for considering the hierarchical level of the element to be retrieved. For CAS queries, we investigate several mappings from INEX queries to our query language XIRQL, where we tried to introduce different degrees of vagueness. Both approaches yield good retrieval results, but still leave room for improvement.

Abstract

Duisburg-Essen, Univ., Diss. 2009 In recent years there has been a growing realisation in the IR community that the interaction of searchers with information is an indispensable component of the IR process. As a result, issues relating to interactive IR have been extensively investigated in the last decade. This research has been performed in the context of unstructured documents or in the context of the loosely-defined structure encountered in web pages. XML documents, on the other hand, define a different context, by offering the possibility of navigating within the structure of a single document, or of following links to other documents. Relatively little work has been carried out to study user interaction with IR systems that make use of the additional features offered by XML documents. As part of the INEX initiative for the evaluation of XML retrieval, the INEX interactive track has focused on interactive XML retrieval since 2004. Here user friendly exposition to various features of XML documents is provided and some new features are designed and implemented to enable searchers to have access to their desired information in an efficient manner. In this study interaction entails three levels: query formulation, inspecting result list, and examining the detail. For query formulation, suggesting related terms is a conventional method to assist searchers. Here we investigate the related terms derived from two different co-occurrence units: elements and documents. In addition, contextual aspect is added to facilitate the searchers for appropriate selection of terms. Results showed the usefulness of suggesting related terms and some what acceptance of the contextual related tool. For inspecting the result list, classic document retrieval systems such as web search engines retrieve whole documents, and leave it to the searchers to collect their required information from possibly a lengthy text. In contrast, element retrieval aims at a focused view of information by pointing to the optimal access points of the document. A number of strategies have been investigated for presenting result lists. For examining the detail of a document, traditionally the complete document is presented to a searcher and here again the searcher has to put in effort to reach its required information. We investigated the use of additional support such as a table of contents along with document detail. In addition, we also investigated graphical representations of documents depicting its structure and granularity of retrieved elements along with their estimated relevance. Here the table of contents was found to be a very useful features for examining details. In order to conduct the analysis of searcher's interaction, a visualisation technique based on Tree Map was developed. It depicts the search interaction with element retrieval system. A number of browsing strategies has been identified with the help of this tool. The value of element retrieval for searchers and comparison between two focused approaches such as element and passage retrieval system was also evaluated. The study suggests that searchers find elements useful for their tasks and they locate a lot of the relevant information in specific elements rather than full documents. Sections, in particular, appear to be helpful. In order to provide user-specific support, the system needs feedback from searchers, who in turn, are very reluctant to give this information explicitly. Therefore, we investigated to what extent the different features can be used as relevance predictors. Of the five features regarded, primarily the reading time is a useful relevance predictor. Overall, relevance predictors for structured documents seem to be much weaker than for the case of atomic documents.
