Kylie Pybus, Ronald L. Gibbs, Karen Franck, and M. Catalina Aragón
- Abstract
Extension professionals often communicate program outcomes to external stakeholders using impact statements. We developed and evaluated four impact statements for the Expanded Food and Nutrition Education Program (EFNEP). We drafted the statements after conducting literature reviews for core content areas of EFNEP that include diet quality, food resource management, physical activity, and food safety. Subsequently, we evaluated the statements by facilitating expert panels made up of subject matter experts and communication professionals(n=14) from 12 Land-grant Universities. These impact statements aim to support EFNEP and other Extension professionals when communicating program value with key external stakeholders.

4. The Basic Course in Communication: A Critical Intercultural and Participatory Approach
- Author
-
Chelsea Slack
- Abstract
This paper advocates for using critical intercultural and participatory pedagogy as the basis for an introductory communication course. Communication programs are often concerned with the basics -- teaching students to communicate effectively through writing and speaking. Yet the methods for teaching these two classic competencies diverge widely, with some instructors opting for a more traditional approach and others taking a more modern one. A divide also exists in the way today's students are viewed by educators in secondary and, in particular, post-secondary educational institutions. Where some teachers see lamentable shortcomings of millennials and Gen Z, others see infinite possibilities in these students. Either way, colleges and universities are dealing with a generation of students that is more diverse, connected, tech-savvy, and socially aware than ever before. This paper explores the advantages of using critical intercultural pedagogical practices -- practices which are necessarily cooperative, multimodal, and participatory -- to reach the students of today.

- Abstract
The aim of this study is to conduct a situational analysis of the benefits and drawbacks of returning to face-to-face courses in the Leveling Courses of the Universidad de las Fuerzas Armadas ESPE Sede Latacunga during the post-COVID-19 era. This will be done by comparing the virtual study mode in 2022 to the face-to-face mode in 2023. The results of this analysis will assist higher education institutions in creating interventions that promote resilience in students who are transitioning from high school to undergraduate education and reducing dropout rates. The study employs prospective methods that include historical-logical empirical methods and a review of relevant documents. The findings of the study indicate that face-to-face attendance has a positive impact on students' classroom experience. The study also highlights the need for a paradigm shift in higher education based on this experience. The proposed solution involves updating the curricula, embracing the expanded use of information and communication technology (ICT), enhancing students' soft skills, improving pedagogical training, and reinforcing hybridization to provide a defense against constant crises.

- Abstract
This paper seeks to gain insights into teachers' perceptions, and readiness to integrate information and communication technology (ICT) tools in mathematics instruction. A mixed-methods approach was employed, involving surveys and interviews with a sample of high school mathematics teachers. The study involved 90 mathematics teachers working in three senior high schools in Kumasi metropolis in Ghana. The study revealed that teachers generally hold positive perceptions of the benefits of ICT tools in mathematics teaching. They strongly agree that ICT tools enhance students' understanding of mathematical concepts and improve their engagement and motivation in mathematics classes. Teachers also recognize the potential of ICT tools in promoting problem-solving skills and providing opportunities for differentiation and personalized learning. However, opinions regarding student-centered learning, exploration, and creativity through ICT tools were more varied, suggesting a need for further investigation and support in these areas. In addition teachers expressed the need for continuous training on specific tools, curriculum alignment, and assessment methods.

10. The Credibility of Newscasts in Public Service Media in Spain
- Author

Soengas-Pérez, Xosé, Rodríguez-Castro, Marta, and Campos-Freire, Francisco
- Abstract
The audiences of generalist television's newscasts reflect that the viewers' interests and loyalties are constantly changing. Research shows that several elements influence the success of programs and formats, but in this paper, we draw attention to the factors that determine the credibility of newscasts. We also want to know how pluralism is safeguarded in newscasts, as we consider that credibility and pluralism are two intertwined values that influence one another. As credibility is a subjective value, it is required to find new information criteria that is suitable and of the utmost rigor. The main aim is to delve into whether there is a consensus on the basic parameters for the definition, identification, and assessment of credibility of nationwide public service media in Spain. Moreover, we are also interested in whether audience figures can be used to determine the degree of trust of newscasts. The analysis brings forward the observations of researchers, scholars and media professionals that offer a vision on the different approaches that integrate the multiple aspects affecting news consumption and interpretation. We conclude that credibility is a concept composed of multidimensional components, resulting from a process where different filters condition fact perception. That is why a story can have different meanings, related to the different point of views of citizens.

12. Smoke and Mirrors: 2021 Garth Boomer Address and Reflection
- Author

Melitta Hogarth
- Abstract
The power of the coloniser within colonial Australia is clear when we consider how central to the teaching and learning and schooling in Australia is the privileging of Standard Australian English. Prior to 1788, the peoples and the lands of this country were abound with languages. That was until the coloniser exerted their power and insisted on a supposedly monolingual society despite being an amalgamation of various Englishes. Quintessential to maintaining the status quo and assumed power of the coloniser is subject English. I want to query the privileged positioning of subject English and its role in privileging the dominant norm. The subject content, the privileging of the coloniser's language, the silencing of Indigenous voices, even the naming of the subject -- all work to maintain the status quo. In a world where technology auto-corrects and predicts our writings, where 'new' ways of communicating such as emojis are becoming prevalent, where the written word is reduced to memos, text messages and emails, where the evolution of language is studied and yet, the consistent message is that you must excel in Standard Australian English. There has never been a 'pure' English nor a standard Australian English in colonial Australia. Our curriculum makes this explicit when we ask students to explore the evolution of language. In this paper, I share the script from my Garth Boomer address provided in 2021 where I wanted to extend the provocation, I raised in 2019 -- why is Standard Australian English the only means of communication privileged in the Australian Curriculum? And be so bold to ask: could (or should) subject English be renamed? Why not Languages, literacy and communication as found in the Welsh Curriculum or how about, simply, Language Arts?

Lauren Trejo and Sarah M. Ginsberg
- Abstract
This qualitive study examined four communication sciences and disorders (CSD) graduate students' experiences with feedback from CSD faculty members to understand how it affected their relationships with faculty. Review of the literature revealed the importance and impact of feedback; however, it offered little research examining feedback within the field of CSD. Graduate CSD students who completed their undergraduate degrees in CSD were interviewed to reflect on feedback experiences they received from faculty during their undergraduate and graduate education. The students were also presented with two mock papers with differing feedback styles and were asked their reactions to the feedback. It was discovered that feedback received directly contributed to faculty's overall perceived approachability, with more imbalanced critical feedback increasing the perception of unapproachability towards faculty members. Additionally, the feedback modality, language used, and balance of positive and negative comments strongly influenced participant's perception of the feedback being given as an inherently pleasant or unpleasant.

Drew T. Ashby-King, Melissa A. Lucas, and Lindsey B. Anderson
- Abstract
Feedback is a foundational communicative aspect of the teaching/learning processes in introductory communication courses as students seek to improve their presentational speaking skills throughout the term. Drawing on 1,673 qualitative questionnaire responses, this paper explores how students used and interpreted instructor feedback. Through our thematic analysis of a randomly selected subset of 335 responses, we identified two tensions in how students used and interpreted instructor feedback: (1) feedback as a process vs. a product and (2) feedback as integrated into the course structure vs. a justification for a grade. Theoretically, this research extends Feedback Intervention Theory by highlighting the importance and nuance of this communicative process in educational settings. Pedagogically, our findings emphasize the need for discursive opportunities that facilitate the co-construction of meaning surrounding the feedback provided in the introductory communication course.

E. Janiuniene, M. Stonkiene, and M. Šupa
- Abstract
Feedback is identified in the works of researchers as an essential element for improving the learning process of students. Research shows that lecturer's feedback creates value when it provides not only appraisal information but also links to further learning. This type of feedback affects the learner's information behaviour, i.e., encourages searching for additional information and using it in the learning process. The paper aims to analyze the peculiarities of students' information behaviour during feedback. The research object is investigated from an information science perspective, using theories of information behaviour. An exploratory quantitative survey of 111 Communication BA students from Vilnius University, Lithuania, was conducted. The results of the study revealed the characteristics of feedback inspired by information behaviour: the feedback provided by the lecture is the primary source of information; feedback promotes individual information search; timely feedback encourages proactive information behaviour.

Way Kiat Bong and Weiqin Chen
- Abstract
The use of information and communications technology (ICT) in higher education institutions has increased in the past 20 years. While ICT has brought many benefits to students and faculty, research shows that it also creates barriers and challenges for students with disabilities due to the inaccessibility of digital tools and learning materials. Faculty members play an important role in inclusive higher education. Previous studies have emphasised the need to train faculty about digital accessibility to achieve inclusion in higher education. This systematic literature review aims to study existing work on increasing the faculty members' competence in providing accessible and inclusive digital learning materials and environments to students in higher education. Sixteen peer-reviewed papers were included and analysed. Most trainings included topics on disability and awareness, legislation, and methods of producing accessible digital materials and providing inclusive digital learning environments. While surveys and interviews were mostly used to evaluate training outcomes, there was a lack of objective data and commonly accepted instrument for evaluation. Good practices and further research opportunities are identified. This study has implications for researchers and higher education institutions that are interested in research and practice on increasing general competence in digital accessibility and inclusive education.

18. The Notion of 'Information' in Genetics: A Pragmatic Model
- Author
-
Martina Blecic
- Abstract
In this paper I suggest a pragmatic model for the notion of 'information' used in molecular biology in the description of protein synthesis. Discarding any ontological commitments of the term 'information', I propose a view of information based on an analogy with communication. This view could at least supplement the existing information-metaphor that should be updated for two reasons: (i) the concept of information it presupposes, and (ii) the origin of the metaphor itself. Besides, the metaphorical nature of the notion of 'information' is still often overlooked, which leads to a false sense of understanding of the underlying genetic phenomena it should describe. The advantages of a model based on communication, as it is seen by the field of pragmatics, is twofold: (i) it provides a rather simple analogy between human communication and basic genetic processes, and (ii) it supplies the tools for the understanding of the non-literal use of the term 'information'.

21. Middle-Class 'Chavs' from Working-Class Areas? Habitus, the Attainment Gap, and the Commodification of Higher Education among Communication Students in England
- Author
-
Topic, Martina, Diers-Lawson, Audra Diers-Lawson, and Goodman, Christian
- Abstract
The purpose of the article is to compare and contrast higher education and research among public relations and journalism students of middle-class and working-class origin. The paper applied Bourdieu's theory of "habitus" to analyze prejudices against the working class, explores whether working-class students express an anti-education view, and whether the appreciation of education (and research in particular) is a predominantly middle-class attitude. Focus groups and an online questionnaire were used to obtain views of students at a university in Northern England. Triple coding (open, axial, selective) was used and the data was then analyzed and presented using thematic analysis. Findings show that early socialization about education as well as students' type of neighborhoods (habitus) influence studies' views of higher education and research in particular. While the findings show some similarity with views in the literature of the middle-class being more inclined to value education, these findings show that this is true only for those who grow up in middle class areas whereas middle-class students who grew up in working-class areas show working-class attitudes toward education. Equally, working-class students who grew up in middle-class areas show what is usually perceived as a middle-class view of education. Both groups of students show a tendency toward embracing a consumerist view of higher education.

Association for Institutional Research (AIR) and Atcha, Haroon
- Abstract
Institutional researchers are often tasked with assessing why college-wide initiatives succeed or fail. This can be a difficult task: researchers need to discriminate between multiple feasible explanations, work with limited data, and produce compelling narratives. Process tracing is a qualitative methodology that enables researchers to make valid inferences in such circumstances. Process tracing focuses the researcher's attention on the sequence connecting cause and effect. It involves articulating a working theory, generating hypotheses, collecting data, assessing competing hypotheses, revising theory, and producing a narrative connecting cause and effect. This paper describes how to use process tracing for institutional research. It begins by summarizing key concepts, uses a simulated case study to give a brief overview of process tracing, discusses the importance of evidence and transparency in implementing the method, and concludes with a summary of the benefits of process tracing.

- Abstract
Technology education varies across countries depending on the goals they set to achieve. Therefore, comparative research on different technology education approaches can provide a holistic perspective and contribute to the literature. This paper compared the technology-focused courses offered by primary schools in Turkey and Scotland. A qualitative research design was adopted. Data were collected using document review and analyzed using descriptive analysis. The results pointed to differences in technology policies, manifesting themselves in the curricula of the courses offered by the schools. However, the courses also had something in common in terms of structure, goal, content, and approach to learning and teaching. We discussed the differences and similarities based on literature. In order to reveal different dimensions of technology education, comparative education studies that address different countries can be suggested.

28. The Portrayal of the Future as Legitimacy Construction: Discursive Strategies in Highly Ranked Business Schools' External Communication
- Author

Géring, Zsuzsanna, Tamássy, Réka, Király, Gábor, and Rakovics, Márton
- Abstract
In this paper, we investigate how highly ranked business schools construct their legitimacy claims by analysing their online organisational communication. We argue that in the case of higher education institutions in general, and business schools in particular, the discursive formation of these legitimacy claims is strongly connected to the future. Consequently, we utilise corpus-based discourse analysis of highly ranked business schools' website communication by focusing on sentences containing the expression 'future'. At first, we analysed the future-related language use to reveal the general future picture in the corpus. Furthermore, by combining qualitative and quantitative textual data, we identified six typical agency frames (i.e. preparing, shaping, adjusting, exploring, personal future, responsibility) about the future. By examining the co-occurrence of these frames, we were able to identify different discursive strategies. As we connected our findings to general societal phenomena we could interpret why and how business schools utilise these discursive strategies to (re)create and maintain their legitimacy.

Stanislava Gardasevic
- Abstract
This study applies human-centered design principles and involves end users in creating a usable knowledge graph. The aim was to explore the potential advantages of capturing and presenting networked knowledge in a domain for information discovery and decision-making purposes. The case taken for the research is the interdisciplinary Ph.D. program in Communication and Information Sciences (CIS) at the University of Hawai'i at Manoa, and the Ph.D. students are the main user population of this knowledge-graph-based information system. The graph was designed to help this user population successfully progress through the degree by supporting them in information discovery, decision-making, and tacit knowledge exchange within the community. The study was conducted in three stages (i) requirements gathering, (ii) design of graph and its visualizations, and (iii) evaluation of the graph. These stages are presented in three papers. CIS Ph.D. students were involved in all study stages, and the methods applied were: content analysis, semi-structured interviews, website usability study, workshops, and surveys. One of the outputs of this study is a comprehensive CIS Knowledge Graph model and dataset (a rich, multilayered network) that aggregates data from (i) multiple academic websites, (ii) metadata from publications and dissertations relevant to this community, and (iii) crowdsourced student data. Upon evaluating the utility of this dataset with CIS Ph.D. students in different stages of the program, the results show that having such a knowledge graph available can be beneficial, especially for new students, as this approach saves them time and effort when looking for relevant information; helps them anticipate future steps and compare their progress with other students; and supports them in making data-driven decisions--especially concerning choosing research supervisor and collaborators. This study contributes to our understanding of the information needs of interdisciplinary Ph.D. students, showing that most of them rely on information they get from other community members. It produced the knowledge graph model that can be repurposed for other interdisciplinary research settings, and a unique multilayered network dataset with pertinent use scenarios/queries that can serve as a testbed for designing visual analytical approaches for multiplex graphs. Finally, based on the end-user inputs and interactions with the knowledge graph hosted and demonstrated via the Neo4J graph database management system, the study produces the guidelines for designing an information system that will host such a graph and will support end users' needs and requirements, with the emphasis on the tacit knowledge exchange.

Lanigan, Mary L.
- Abstract
This activity helps students conceptualize and apply systems theory principles to a family communication context by having them create personal whole systems using paper, string, index cards, and the floor. In completing this exercise, students see how their subsystems interact and emerge as something greater than the sum of their parts. They also grasp how environmental factors and feedback loops influence change and impact growth. Finally, this exercise helps students identify the complexities and interconnections of individual and family units. Courses: Family Communication. Objectives: At the end of this exercise, students will be able to: (1) describe whole systems, subsystems, environmental factors, and feedback loops; (2) show how multiple subsystems interact and emerge as something greater than the sum of their parts; and (3) see how inputs transform into outputs that contribute to a system's evolution.

31. Key Insights from Climate Communication -- and How They Can Inspire Sustainability in Higher Education
- Author
-
Sippel, Maike
- Abstract
Purpose: To combat climate change and safeguard a liveable future, humanity needs fundamental and rapid social change. The purpose of this paper is to show, why and how climate communication can play an important role to nurture the public engagement needed for this change, and to explore, what higher education for sustainability can learn from climate communication. Design/methodology/approach: The scientific evidence base on climate communication for effective public engagement is summarised into 10 key principles, including "basing communication on people's values", "conscious use of framing" and "turning concern into action". Based on the author's perspective and experience in the university context, implications are explored for sustainability in higher education. Findings: The study provides suggestions for teaching (e.g. complement information with consistent behaviour by the lecturer, integrate local stories and provide students with basic skills to communicate climate effectively), for research (e.g. make teaching for effective engagement the subject of applied research), for universities' third mission to contribute to sustainable development in the society (e.g. provide climate communication trainings to empower local stakeholders) and greening the campus (develop a proper engagement infrastructure, e.g. by a university storytelling exchange on climate action). Originality/value: The study provides an up-to-date overview of climate communication research, which is in itself original. This evidence base holds interesting learnings for institutions of higher education, and the link between climate communication and universities has so far not been explored comprehensively.

34. Discourses on Sustainability in a Network of Argentine Universities: Exploring Representations, Cultural Roots and Transformative Processes
- Author

Norton, Laura Soledad, Sarrica, Mauro, Lombardi, Raffaele, and Peruzzi, Gaia
- Abstract
Purpose: The paper aims to reflect on the function(s) served by the network of Argentine universities for environmental management and social inclusion (UAGAIS), including sharing information, empowering its members and fostering political action. To these functions, the authors add that networks play a prominent role in promoting culturally and locally meaningful representations of sustainability, and as rhetorical devices for positioning universities within the national, regional and international context. Design/methodology/approach: Drawing upon a constructionist and cultural approach, two analyses were conducted: the first an analysis of the institutional webpages of selected UAGAIS universities; the second, a discursive analysis of five in-depth interviews conducted with UAGAIS representatives. Both analyses looked at local and cultural specificities of sustainability in higher education, perceptions of the sustainable development goals (SDGs) and the role of UAGAIS for individuals, universities and other social actors involved. Findings: Results show how sustainability is used in institutional communication and in the interviews to frame the role of the university in the community. The network serves information and empowering functions, as the same time acting as an amplifier of the activities performed under the "Extensión" framework. Such a culturally situated approach to sustainability is used to engage different social actors and to stress commitment of universities with the environmental and social needs of local communities. Originality/value: The results underline the role played by networks in transformative process. Anchored to the culturally rooted "Extensión" concept, the examined network serves as a place to advance the social commitment and the local understanding of sustainability. Moreover, it is rhetorically used to challenge the status quo and advocate for systemic change.

Ahmad Tajuddin, Siti Nor Amalina, Bahari, Khairul Azam, Al Majdhoub, Fatima M., Balraj Baboo, Shanthi, and Samson, Harlina
- Abstract
Purpose: The purpose of this paper is to examine the industry's expectations on the key employability skills of fresh graduates in the communication and media industry. The Fourth Industrial Revolution has raised the question of whether the university should produce work-ready graduates with employability skills. Driven by the theory of human capital, society expects higher education to produce graduates with skills that are useful in their workplace. Design/methodology/approach: The data were gathered primarily through a quantitative survey, which was later extended to include qualitative interviews. Quantitatively, questionnaires were completed by 313 employers from the middle and top-level management from the communication and media industry. This study also expands on qualitative data through in-depth interviews with nine respondents who were among key decision-makers of recruiting graduates to garner their insights on required employability skills. Findings: The findings revealed the following employability skills required by the industry in the Fourth Industrial Revolution: communication, ICT or digital, leadership, interpersonal, and personal qualities skills. Research limitations/implications: These findings are beneficial to education providers as well as media and communication industries in preparing students and developing their skills to adapt to the changes in the workplace. Originality/value: The authors provide an empirical understanding of industry expectations towards employability skills in the Fourth Industrial Revolution of the communication and media industry within the Malaysian context.

- Abstract
This review paper synthesizes peer-reviewed empirical research published between 2010 and 2021 about wildland fire communication practices. Our goal was to systematically review and provide an overview of how wildland fire communication has been empirically studied, and theoretical and methodological underpinnings and representativeness of this work. We found that researchers employ diverse theoretical and methodological approaches, yet most work originates from the western United States or Australia. Studies were published in diverse disciplinary journals, most frequently looked at residents as study subjects, and many sought to understand the effectiveness of communication. There is a need to build theoretical and methodological consistency in wildland fire communication research.

Extensive research has been reported on MIMO systems for complex environments. It is noted that many communications studies make use of the channel matrix of transmitters and receivers, signal vectors, SNR, and eigenvalues. However, the channel matrix is often expressed in terms of channel modeling, and the detailed statistical characteristics of the channel in terms of physical characteristics of atmospheric turbulence, particulate matter, and rough surfaces and terrain are often not explicitly shown. This paper discusses the inclusion of expressions of physical characteristics of the random medium in the channel matrix. Therefore, the key point of this paper is that the channel matrix is explicitly given in terms of the actual physical parameters of the random environment using the mutual coherence function and stochastic Green's functions; we call this a 'physics-based' communications model. This paper presents a formulation of physics-based communications models in the presence of a random medium based on analytical statistical EM theory. We use the keyhole MIMO as an example to show the key points of this approach. It is hoped that this study may help extend channel modeling to include analytical statistical EM theory for atmospheric turbulence, ocean turbulence, and rough terrain. [ABSTRACT FROM AUTHOR]

This paper explores partnership representations in the Trustees' Annual Reports & Accounts (TARA) of English and Welsh international non-governmental organisations (INGOs). INGOs are prominent global actors, whose TARA serve important accountability purposes, while also acting as key fundraising communications. The study uses thematic analysis to examine 83 TARA published between 2014 and 2018 by 29 INGOs. Findings show that in these TARAs' narrative sections, partnership relationships are largely described using the language of collaboration, yet accord the INGO the primary role. In the subsequent managerial and financial sections, however, these relationships are presented as a hierarchy, focusing on upwards accountability from project partners to the INGO. These presentations suggest that INGOs continue to embed power inequalities in their partnership relationships. Furthermore, drawing on stakeholder theory, this exploratory study argues that the contradiction found demonstrates that INGO reporting prioritises legitimation rather than authenticity, and obfuscates understanding of international development partnership relationships.

Cyclopropane rings are an important structural motif frequently found in many natural products and pharmaceuticals. Commonly, biocatalytic methodologies for the asymmetric synthesis of cyclopropanes rely on repurposed or artificial heme enzymes. Here, we engineered an unusual cofactor‐independent cyclopropanation enzyme based on a promiscuous tautomerase for the enantioselective synthesis of various cyclopropanes via the nucleophilic addition of diethyl 2‐chloromalonate to α,β‐unsaturated aldehydes. The engineered enzyme promotes formation of the two new carbon‐carbon bonds with excellent stereocontrol over both stereocenters, affording the desired cyclopropanes with high diastereo‐ and enantiopurity (d.r. up to 25:1; e.r. up to 99:1). Our results highlight the usefulness of promiscuous enzymes for expanding the biocatalytic repertoire for non‐natural reactions., Engineering of a promiscuous 4‐oxalocrotonate tautomerase (4‐OT) resulted in an unusual cofactor‐independent cyclopropanation enzyme that promotes the stereoselective addition of diethyl 2‐chloromalonate to substituted cinnamaldehydes to afford various cyclopropanes with high diastereo‐ and enantiopurity.

The reaction of a borylnitrene with carbon dioxide is studied under cryogenic matrix isolation conditions. Photogenerated CatBN (Cat=catecholato) reacts with CO2 under formation of the cycloaddition product CatBNCO2, a 3‐oxaziridinone derivative, after photoexcitation (>550 nm). The product shows Fermi resonances between the CO stretching and ring deformation modes that cause unusual 13C and 18O isotopic shifts. A computational analysis of the 3‐oxaziridinone shows this cyclic carbamate to be less strained than an α‐lactone or an α‐lactame., Triplet borylnitrene 1 reacts photochemically (λ>550 nm) under cryogenic matrix isolation conditions with CO2, which is known for its high thermodynamic and kinetic stability, to give a strained and unprecedented 3‐oxaziridinone motif 2.

This paper advocates for spatial simultaneous functioning (SSF) over time division multiple access (TDMA) in joint communication and sensing (JCAS) scenarios for improved resource utilization and reduced interference. SSF enables the concurrent operation of communication and sensing systems, enhancing flexibility and efficiency, especially in dynamic environments. The study introduces joint design communication and sensing scenarios for single input single output (SISO) and multiple input multiple output (MIMO) JCAS receivers. An MIMO-JCAS base station (BS) is proposed to process downlink communication signals and echo signals from targets simultaneously using interference cancellation techniques. We evaluate the communication performance and sensing estimation across both Rayleigh and measured realistic channels. Additionally, a deep neural network (DNN)-based approach for channel estimation and signal detection in JCAS systems is presented. The DNN outperforms the traditional methods in the bit error rate (BER) versus signal-to-noise ratio (SNR) curves, leveraging its ability to learn complex patterns autonomously. The DNN's training process fine-tunes the performance based on specific problem characteristics, capturing the nuanced relationships within data and adapting to varying SNR conditions for consistently superior performance compared to the traditional approaches.

- Abstract
Fiber-to-the-home (FTTH) technology is a promising solution for providing advanced service delivery to end-users, but its implementation requires substantial capital expenditures. To minimize investment risks and aid decision-making for access service providers, we propose a game theoretic framework based on a modified Nash genetic algorithm. We illustrate how this framework can be applied to analyze the competition between access providers offering a flat-rate FTTH service on multiple geographical areas. Each provider determines its price for all areas simultaneously and decides whether to invest on a particular area depending on the anticipated revenues. Two distinct demand models are adopted to describe different types of consumer behavior. A solution engine, based on a modified mixed-variable Nash genetic algorithm is implemented under an open-source license. The significance and practical implications of the equilibrium points obtained for both single and multiple area games are discussed. The proposed framework and the solution engine developed, aid both providers and regulatory bodies to analyze competitive environments. They can also be used to implement decision support tools for similar problems as well. The paper concludes by pointing out further research directions in this context. [ABSTRACT FROM AUTHOR]

Prussian blue analogs (PBAs) are considered as reliable and promising cathode materials for aqueous Zn‐ion batteries (AZIBs), but they suffer from low capacity and poor cycling stability due to insufficient active sites and structural damage caused by the ion insertion/extraction processes. Herein, a template‐engaged ion exchange approach has been developed for the synthesis of Co‐substituted Mn‐rich PBA hollow spheres (CoMn‐PBA HSs) as cathode materials for AZIBs. Benefiting from the multiple advantageous features including hollow structure, abundant active sites, fast Zn2+ ion diffusion, and partial Co substitution, the CoMn‐PBA HSs electrode shows efficient zinc ion storage properties in terms of high capacity, decent rate capability and prolonged cycle life., Co‐substituted Mn‐rich Prussian Blue Analog (PBA) hollow spheres (CoMn‐PBA HSs) are rationally designed and synthesized through an efficient self‐templating approach. Benefiting from the hollow structure and partial Co substitution, the CoMn‐PBA HSs electrode exhibits enhanced zinc ion storage performance with high capacity, favorable rate capability, and impressive cycling stability.

Resonance Raman optical activity (RROA) possesses all aspects of a sensitive tool for molecular detection, but its measurement remains challenging. We demonstrate that reliable recording of RROA of chiral colorful compounds is possible, but only after considering the effect of the electronic circular dichroism (ECD) on the ROA spectra induced by the dissolved chiral compound. We show RROA for a number of model vitamin B12 derivatives that are chemically similar but exhibit distinctively different spectroscopic behavior. The ECD/ROA effect is proportional to the concentration and dependent on the optical pathlength of the light propagating through the sample. It can severely alter relative band intensities and signs in the natural RROA spectra. The spectra analyses are supported by computational modeling based on density functional theory. Neglecting the ECD effect during ROA measurement can lead to misinterpretation of the recorded spectra and erroneous conclusions about the molecular structure., A strong influence of electronic circular dichroism on the measurement of resonance Raman optical activity of colorful chiral compounds is reported for a series of vitamin B12 derivatives. Neglecting this effect can lead to misinterpretation of recorded spectra, and seriously erroneous conclusions about molecular structure and chirality.

Copolymers are the answer to property limitations of homopolymers. In order to use the full variety of monomers available, catalysts active in more than one polymerization mechanism are currently investigated. Iron guanidine catalysts have shown to be extraordinarily active in ROP of lactide and herein prove their versatility by also promoting ATRP of styrene. The presented iron complex is the first polymerizing lactide and styrene simultaneously to a defined block copolymer in a convenient one‐pot synthesis. Both mechanisms work hand in hand with ROP using the dominantly present FeII species on the dormant side of the ATRP equilibrium. This orthogonal copolymerization by a benign iron catalyst opens up new pathways to biocompatible polymerization procedures broadening the scope of ATRP applications., Orthogonal catalysis combining two polymerization mechanisms in a one‐pot synthesis enables facile production routes to block copolymers. An iron guanidine catalyst is able to copolymerize styrene via ATRP and lactide via ROP simultaneously. By using the FeII species on the dormant side of the ATRP equilibrium for ROP both mechanisms proceed in a controlled manner without interference.

We present a computational analysis of hexaphenylethane derivatives with heavier tetrels comprising the central bond. In stark contrast to parent hexaphenylethane, the heavier tetrel derivatives can readily be prepared. In order to determine the origin of their apparent thermodynamic stability against dissociation as compared to the carbon case, we employed local energy decomposition analysis (LED) and symmetry‐adapted perturbation theory (SAPT) at the DLPNO‐CCSD(T)/def2‐TZVP and sSAPT0/def2‐TZVP levels of theory. We identified London dispersion (LD) interactions as the decisive factor for the molecular stability of heavier tetrel derivatives. This stability is made possible owing to the longer (than C−C) central bonds that move the phenyl groups out of the heavily repulsive regime so they can optimally benefit from LD interactions., Carbon‐Carbon bonds are exceptional as demonstrated for the hexaphenylditetrels where attractive London dispersion interactions are the decisive factor for the thermodynamic stabilities of tetrels other than carbon. Structural and energetic comparisons show that even though hexaphenylethane displays the largest dispersion energy between the two molecular halves, it has remained elusive because of even larger Pauli repulsion of the phenyl moieties that are forced in close contact due to the C−C bond that is the shortest in this series.

Over half a century since the description of the first antiviral drug, “old” re‐emerging viruses and “new” emerging viruses still represent a serious threat to global health. Their high mutation rate and rapid selection of resistance toward common antiviral drugs, together with the increasing number of co‐infections, make the war against viruses quite challenging. Herein we report a host‐targeted approach, based on the inhibition of the lipid kinase PI4KIIIβ, as a promising strategy for inhibiting the replication of multiple viruses hijacking this protein. We show that bithiazole inhibitors of PI4KIIIβ block the replication of human rhinoviruses (hRV), Zika virus (ZIKV) and SARS‐CoV‐2 at low micromolar and sub‐micromolar concentrations. However, while the anti‐hRV/ZIKV activity can be directly linked to PI4KIIIβ inhibition, the role of PI4KIIIβ in SARS‐CoV‐2 entry/replication is debated., Host targeting is a promising approach for the development of broad‐spectrum antiviral agents (BSAAs) endowed with a high genetic barrier to resistance and efficacy against viral mutants resistant to conventional antiviral drugs. We show that bithiazole inhibitors of the host lipid kinase PI4KIIIβ block the replication of human rhinoviruses (hRV), Zika virus (ZIKV) and SARS‐CoV‐2 at low micromolar and sub‐micromolar concentrations. Moreover, inhibition of SARS‐CoV‐2 entry seems to be connected with an additional unknown target.
