Flexible curriculum design for quantitative skills development: Building on the insights gained during COVID-19
Authors: Janse van Vuuren Corlia , Muller Annari , Strydom Francois
Published: June 2023

Before the COVID-19 pandemic, technology-enhanced learning and its relation to student engagement, and the necessity of good student-staff relationships for creating a successful education environment were evident. The COVID-19 pandemic forced higher education to adapt to a challenging technology-led learning environment that demanded, inter alia, high levels of flexibility and human-centredness. Valuable lessons were learned that highlighted new perspectives on curriculum design and delivery in a normalised, technology-driven environment. Against the background of COVID-19-related literature on teaching andlearning, the authors reflect on their insights regarding curriculum design and delivery of two quantitative skills modules during the COVID-19 pandemic, and its impact on further curriculum planning. The focus of the article is on the intentional flexibility built into curriculum offerings during 2020-2022. The study reviewed flexibility on three levels, namely student, facilitator (staff) and delivery levels, through a multi-method research methodology.Quantitative data related to the academic performance of 2 949 students enrolled for the two quantitative skills modules from 2020 to 2022. Qualitative data related to themes through thematic analysis of student and facilitator surveys, focusgroup discussions and semi-structured interviews. The improved student academic performance reported by the study could be attributed to, amongst other factors, 1) flexibility of the selected delivery option, 2) positive staff and student experiences and engagement, and 3) intentional inclusion of activities promoting student-staff relationships. The good academic results obtained during the pandemic led to important curriculum decisions for a normalised future for thesemodules, which will be built on flexibility and human-centredness. Among these decisions is to continue presenting the modules in an online environment, even though traditional face-to-face teaching options are available.
Technology-driven proctoring: Validity, social justice and ethics in higher education
Authors: Archer Elizabeth
Published: June 2023

The COVID-19 pandemic has led to rapid change, unprecedented in higher education. One such change has been the almost complete shift to online assessment. The simultaneous employment of online assessment and proctoring has not enjoyed the rigorous academic debate and research traditionally associated with such shifts in academia. This engagement is essential and this article aims to discuss aspects of social justice, ethics and the validity of digital proctoring to the burgeoning debate. Digital proctoring is a lucrative industry (Coghlan Miller & Paterson, 2021), notwithstanding the admitted opportunities for cheating, irrespective of the intensity of overwatch. Digital proctoring is marketed and has become entangled with issues of institutional reputation and the legitimacy of qualifications. The student seems to be a secondary consideration compared to the technocratic digital proctoring arena. However, the introduction of online assessment, specifically with digital proctoring, impacts the assessment’s validity by introducing intervening variables into the process. The drive to detect and prevent online cheating has led to algorithmic proliferation. This technologically driven approach has embedded social injustice and questionable ethics and validity into the assessment systems. This article examines the social justice, ethical and validity issues around technological proctoring under the grouped themes: Emotional factors; Racial and/or skin colour; Digital literacy and Technology; and Disability. However, the COVID-19 pandemic driven shifts have provided the unprecedented opportunity to elevate assessment from recall to critical thinking and application based assessment. An opportunity to ensure that our assessment is valid, assesses higher-order learning, and truly evaluates the concepts we wish to assess.

Authors: Polyák Zsolt
Published: June 2023

Aim: In the study, the author describes the cooperation and activities of the general police force and the complementary law enforcement agencies as a possible good practice from the aspect of the public security net operated in Mórahalom district.Methodology: With regard to the role of local authorities in local policing and public security nets, the author has conducted a secondary research by processing national legal regulations, professional studies and statistical data. In order to develop an objective assessment, the author conducted a focus group discussion with several participants in the Mórahalom district to find out about the measures taken by the municipalities in the field of local policing and the practical functioning of the public security net.Findings: In order to increase the subjective sense of security of the population and to achieve the desired level of objective security, it is advisable and necessary to maintain and operate the public security net and to further strengthen the current practice, as it contributes significantly to achieving a higher level of public security.Value: The experiences of the public security net described in the study can be used in practice by local law enforcement officers, as well as by the leaders of other municipalities and police academics. The author suggests a segment of the development of public security that could further strengthen the broad spectrum of public support that already exists.
A kórház – mint kritikus infrastruktúra – biztonságának aktuális kérdései
Authors: Mészáros István
Published: June 2023

Aim: To explore the current security issues of in-patient care institutions from the perspective of critical infrastructure protection activities.Methodology: Examination of EU and national regulations on critical infrastructure, analysis of the legislative environment applicable to hospitals in security areas, based on practical experience.Findings: The regulation of critical infrastructure protection in the European Union and in Hungary is constantly evolving, and the development of further regulation affecting hospital safety is showing a mixed picture. The new EU Directive, which aims to increase resilience, will allow the introduction of standard methodological approaches that will impact on the complex security level of the hospital through the security of the patient care process.Value: The static operational critical infrastructure security planning practice has evolved over the past seven years, but further development of the planning methodology is needed to enable the organization to respond dynamically to the fundamental challenges of the healthcare sector and its ever-changing environment. To this purpose, standardized planning practices are available, applied and used in production at international level.
Műtárgyak védelme a légiközlekedés során
Authors: Chikán-Sonne Zoltán
Published: June 2023

Aim: The aim of the study is to provide information on the specific security rules for the transport of objects of virtu by air.Methodology: The study draws on international and national legislation governing aviation security, the conventions of the International Civil Aviation Organization (ICAO) and the educational resources developed based on these conventions.Findings: Several options are available to minimize the risk of damage during the transport of objects of virtu and to implement specific protection rules. When transporting objects of virtu, not only the risk of damage due to packaging and handling, but also the additional risks due to additional handling, dismantling, and packaging for screening for aviation security must be taken into account. The main focus in aviation security is on preventing the placement of prohibited articles in cargo, which must be balanced within the framework of the rules with the need to protect the integrity of the objects of virtu.Value: The rules and objectives of aviation security and their practical implementation have been the subject of many studies, but, to the author's knowledge, no detailed theoretical study has yet been carried out on the summary of security solutions for the special type of goods transported by air, i.e. objects of virtu.
THE IMPACT OF ESG CONTROVERSIES AND ESG PERFORMANCE ON STOCK RETURN VOLATILITY
Authors: Sandu Diana-Mihaela
Published: June 2023

This study examines the impact of environmental, social and governance performance and controversies on stock return volatility. For this purpose, I considered a sample of 1095 European companies from 23 countries during 2019–2022 and it was applied panel regression. This study found a direct influence of ESG controversies on stock return volatility, but the coefficient of the dependence is close to zero. Similarly, the ESG performance has a direct impact on volatility and the coefficient of dependence is different from zero. This result shows that companies with a better performance on ESG face higher stock return volatility. The study findings enrich the academic literature and can help investors in the investment decisions making.
FIRM-LEVEL DETERMINANTS OF ACCESS TO EXTERNAL FINANCE AND IMPACT OF EXTERNAL FINANCE ON FIRM PERFORMANCE
Authors: Pascoe Pulkeria , De Barcellos Marcia Dutra , De Steur Hans , Schouteten Joachim , Tundui Hawa Petro , Gellynck Xavier
Published: June 2023

This cross-sectional study employs resource-based view and resource dependence theories to examine the determinants of access to external finance at firm-level and the effect of access to external finance on performance of 328 agri-food firms. Applying binary logistic regression, results indicate that firm age, ownership, sources of financing, and firm location were significant predictors of access to external finance. The effect of access to external finance on firm performance analyzed using linear regression was positive and significant. Therefore, firm-specific characteristics are crucial in the decision to access external finance. Access is easier for older firms in small cities that rely on informal sources of financing. Family firms are more vulnerable to external finance than non-family firms. Furthermore, access to external financing is associated with better firm performance. The findings of this study are useful for managers making financing decisions and for stakeholders involved in micro and small enterprises financing.
FACTORS INFLUENCING FRAUDULENT TRANSACTIONS FROM BIG DATA PERSPECTIVE
Authors: Levon Fabiana , Maknickienė Nijolė
Published: June 2023

This article focuses on fraudulent behaviour and patterns as well as ways of detecting such patterns by using Big Data. The study analyses scientific articles to examine types of financial fraud and their detection techniques as well as develops a model that is based on factors characterizing fraudulent credit card transactions made across USA. Regression analysis, correlation and descriptive statistics analysis is applied. Statistically significant results are found indicating a causal relationship between fraudulent transactions and transactions made in Alaska, during the month of October and on a Thursday. Although, the impact of these relationships is relatively small. Expanding the dataset with more numerical variables that could be used for identifying fraudulent transactions is advised for future research as to better the overall fit of the model.

Published: June 2023

The intrinsic statistical properties and correlations of short gamma-ray bursts (SGRBs) have not been fully determined, due to the limitations of observations. In this paper, we compile a more extensive sample of 82 SGRBs with measured redshifts and present a comprehensive study of their intrinsic characteristics. We obtain the median values of the intrinsic duration (T
90,z), peak energy (E
p,z), isotropic energy (E
iso), and peak luminosity (L
iso) as 0.47 s, 466 keV, 8.21 ×1050 erg, and 3.22 × 1051 erg s−1, respectively. We update the spectrum–energy correlations, and report

Multicollision Internal Shock Lepto-hadronic Models for Energetic Gamma-Ray Bursts (GRBs)
Authors: Rudolph Annika , Petropoulou Maria , Bošnjak Željka , Winter Walter
Published: June 2023

For a subpopulation of energetic gamma-ray bursts (GRBs), a moderate baryonic loading may suffice to power ultra-high-energy cosmic rays (UHECRs). Motivated by this, we study the radiative signatures of cosmic-ray protons in the prompt phase of energetic GRBs. Our framework is the internal shock model with multicollision descriptions of the relativistic ejecta (with different emission regions along the jet), plus time-dependent calculations of photon and neutrino spectra. Our GRB prototypes are motivated by Fermi-Large Area Telescope-detected GRBs (including GRB 221009A) for which further, owing to the large energy flux, neutrino nonobservation of single events may pose a strong limit on the baryonic loading. We study the feedback of protons on electromagnetic spectra in synchrotron- and inverse Compton-dominated scenarios to identify the multiwavelength signatures, to constrain the maximally allowed baryonic loading, and to point out the differences between hadronic and inverse Compton signatures. We find that hadronic signatures appear as correlated flux increases in the optical-UV to soft X-ray and GeV–TeV gamma-ray ranges in the synchrotron scenarios, whereas they are difficult to identify in inverse Compton-dominated scenarios. We demonstrate that baryonic loadings around 10, which satisfy the UHECR energetic requirements, do not distort the predicted photon spectra in the Fermi Gamma-Ray Burst Monitor range and are consistent with constraints from neutrino data if the collision radii are large enough (i.e., the time variability is not too short). It therefore seems plausible that under the condition of large dissipation radii a population of energetic GRBs can be the origin of the UHECRs.

= 71,7–61,6 A+ lines, and 900 μm continuum show several new features, which have not been identified in previous observations. The dense gas probe (H13CN, SiO, CH3OH) images are dominated by a pair of northeast-southwest elongated filaments, which may be the main body of CO 0.02–0.02. Two striped patterns perpendicular to each other (F1 and F2) and a high-velocity feature (HV), which appear in different velocity ranges, were prominent in the CO image. An emission hole that may represent an expanding feature was found in the F1 velocity range. F2 appeared to align along the western edge of a 20 pc × 13 pc ellipse (the Large Shell) identified in the single-dish CO map. The HV contains eight compact clumps at the positive high-velocity end of the CO emissions. Based on these results, we propose a formation scenario for CO 0.02–0.02; internal explosions of supernovae, external perturbations by the Large Shell, and gravitational acceleration by a less-luminous star cluster have formed CO 0.02–0.02 in its current state.

We present near-infrared (NIR) and optical observations of the Type Ic supernova (SN Ic) SN 2021krf obtained between days 13 and 259 at several ground-based telescopes. The NIR spectrum at day 68 exhibits a rising K-band continuum flux density longward of ∼2.0 μm, and a late-time optical spectrum at day 259 shows strong [O i] 6300 and 6364 Å emission-line asymmetry, both indicating the presence of dust, likely formed in the SN ejecta. We estimate a carbon-grain dust mass of ∼2 × 10−5
M
⊙ and a dust temperature of ∼900–1200 K associated with this rising continuum and suggest the dust has formed in SN ejecta. Utilizing the one-dimensional multigroup radiation-hydrodynamics code STELLA, we present two degenerate progenitor solutions for SN 2021krf, characterized by C–O star masses of 3.93 and 5.74 M
⊙, but with the same best-fit 56Ni mass of 0.11 M
⊙ for early times (0–70 days). At late times (70–300 days), optical light curves of SN 2021krf decline substantially more slowly than those expected from 56Co radioactive decay. Lack of H and He lines in the late-time SN spectrum suggests the absence of significant interaction of the ejecta with the circumstellar medium. We reproduce the entire bolometric light curve with a combination of radioactive decay and an additional powering source in the form of a central engine of a millisecond pulsar with a magnetic field smaller than that of a typical magnetar.
Ocean Justice: Rethinking Global Justice from the Sea
Authors: Scharenberg Antje , Armstrong Chris
Published: June 2023

Discussions of global justice urgently need to include the question of the sea, and to foreground the concept of ocean justice. The ocean is discussed here as a site from which to address planetary environmental destruction, issues of global inequality and racialised violence - but
also as a political laboratory from which radical alternatives to the current global order may emerge. Discussion focuses on the Blue New Deal; Blue Acceleration - the current, largely unregulated, push for growth from ocean-based industries including fossil fuel extraction, the exploitation
of marine genetic resources, and industrial fishing; maritime migration and the racialised sea; the lack of regulation of the high seas; the possibilities this creates for radical sea alternatives-for reimagining the sea and ocean justice from the perspective of maritime civil society. Through
a New Blue Deal, the ocean can be a starting point for addressing both the global ecological crisis and issues of global injustice.
The End of Education Policy?
Authors: Gunter Helen M. , Courtney Steven J.
Published: June 2023

Education is no longer the responsibility of education policy as public policy. Instead the provision of and access to school places has been relocated away from the desk of publicly elected representatives and appointed accredited professionals, to a range of private sites controlled
by oligarchic club interests engaged in market exchanges: first, little monarchies, such as the Harris family; second, little representatives, such as the Confederation of School Trusts (CST); and third, little contractors, such as grammar schools. We use these three examples to examine the
restoration of private provision, access and control as an example of depoliticisation. This trend is evident in a shift in decision-making about the purposes of education, away from public policy funded by the public, in the name of the public and accountable to the public, and towards providers
and consumers, and towards nowhere in particular. Debates about and for educational issues are on no-one's agenda. We argue that these trends validate the analytical judgment that education is no longer a matter for public policy but instead has been relocated to corporate market exchanges
within and beyond the nation state.
La CED, péché originel de la défense européenne ?
Authors: Raflik Jenny
Published: June 2023

Depuis l’échec du projet de Communauté européenne de défense, en août 1954, les pays européens ont exploré de multiples pistes pour tenter de construire une « Europe de la défense », mais avec des succès très mitigés. L’échec de la CED a-t-il pesé sur les tentatives suivantes ? C’est l’hypothèse de cette communication, qui tentera de mettre en avant quelques écueils nés de la querelle de la CED sur lesquels ont buté les projets d’Europe de la défense depuis 1954, et notamment trois problématiques récurrentes : celle du lien entre Europe de la défense et OTAN ; celle des frontières géographiques de l’Europe à construire ; et enfin les contradictions de la politique française.
Jouir n’est pas consentir
Authors: Salomon Diane , Daube Mélodie
Published: June 2023

Dans cet article, deux psychologues cliniciennes tentent de saisir ce qu’est la jouissance sexuelle lorsqu’elle est éprouvée par un enfant ou adolescent prépubère au cours d’une agression sexuelle. Confondu avec son agresseur, le sujet victime est convaincu qu’il a pris du plaisir, voire qu’il a consenti à l’acte sexuel. Lorsqu’il est devenu adulte, enfermé dans la répétition, la jouissance réapparaît par la voie du masochisme. En précisant les mécanismes physiologiques et psychiques à l’origine de la jouissance sexuelle, les auteures démontrent que jouir n’est pas consentir, ni à l’étreinte sexuelle imposée, ni au scénario pervers qui l’accompagne, y compris dans les suites de l’événement. Au contraire, la recherche de cette jouissance sexuelle serait la seule voie possible pour lutter contre l’agresseur.

Cet article revient sur un dispositif innovant, le Service d’accrochage et de mobilisation des invisibles ( sami ), destiné à détecter et remobiliser les jeunes ni en études, ni en emploi, ni en formation ( neef ) vivant en milieu rural. L’objectif de cette étude collaborative est de comprendre, à partir des entretiens informels et des actions collectives, la démarche d’aller vers des professionnels tout en appréhendant la spécificité du public à hauteur du terrain. Ce travail repose sur l’hypothèse qu’il faut une démarche nouvelle pour amener des jeunes invisibles du milieu rural vers l’insertion. L’article permet de comprendre comment la mise en œuvre de l’aller vers est un outil indispensable pour redynamiser ces jeunes et favoriser une relation aboutissant à un accompagnement co-construit, tout en donnant une image plus précise de ce public et de son besoin d’un accompagnement dans la durée.
La théorie néo-sentimentaliste des valeurs à l’épreuve de sa formalisation logique
Authors: Butreau Samuel
Published: June 2023

La théorie néo-sentimentaliste des valeurs considère qu’un objet est pourvu d’une certaine valeur si et seulement si l’émotion que cette valeur est propre à occasionner est appropriée à cette situation. Mais, lorsqu’on cherche à transcrire cette relation biconditionnelle dans le formalisme de la logique des prédicats, on constate que la notion de valeur, également appelée propriété évaluative ou objet formel dans ce contexte, est sous-déterminée. On constate également que, si l’on spécifie davantage cette notion en la faisant dépendre de la réponse émotionnelle, elle ne peut même plus représenter une valeur, mais seulement une instanciation de valeur, laquelle reste sous-déterminée. Si bien que la relation biconditionnelle se révèle n’être pas à la hauteur de l’ambition épistémique qu’y place pourtant le néo-sentimentalisme.
Probiotic interventions promote metabolic health in high fat-fed hamsters in association with gut microbiota and endocannabinoidome alterations

Published: June 2023

Probiotics represent a promising tool to improve metabolic health, including lipid profiles and cholesterol levels. Modulation of the gut microbiome and the endocannabinoidome – two interrelated systems involved in several metabolic processes influenced by probiotics – has been proposed as a potential mechanism of action. This study establishes the impact of probiotics on metabolic health, gut microbiota composition and endocannabinoidome mediators in an animal model of hypercholesterolaemia. Syrian hamsters were fed either a low-fat low-cholesterol or high-fat high-cholesterol (HFHC) diet to induce hypercholesterolaemia and gavaged for 6 weeks with either Lactobacillus acidophilus CL1285, Lactiplantibacillus plantarum CHOL-200 or a combination of the two. Globally, probiotic interventions ameliorated, at least partially, lipid metabolism in HFHC-fed hamsters. The interventions, especially those including L. acidophilus, modified the gut microbiota composition of the small intestine and caecum in ways suggesting reversal of HFHC-induced dysbiosis. Several associations were observed between changes in gut microbiota composition and endocannabinoidome mediators following probiotic interventions and both systems were also associated with improved metabolic health parameters. For instance, potential connexions between the Eubacteriaceae and Deferribacteraceae families, levels of 2‑palmitoylglycerol, 2‑oleoylglycerol, 2‑linoleoylglycerol or 2‑eicosapentaenoylglycerol and improved lipid profiles were found. Altogether, our results suggest a potential crosstalk between gut microbiota and the endocannabinoidome in driving metabolic benefits associated with probiotics, especially those including L. acidophilus, in an animal model of hypercholesterolaemia.

Authors: Fernández-Basanta Sara , López-Villasenín Silvia , Freijomil-Vázquez Carla , Movilla-Fernández María-Jesús , Coronado Carmen
Published: June 2023

Background:

Nurses play key roles as vaccination agents and frontline workers who deal with prejudice and misinformation. This study examined the attitudes and perceptions of nursing students regarding corona-virus disease 2019 (COVID-19) vaccination and its social and institutional management.

Method:

This qualitative study consisted of an exploratory phase involving first- and fourth-year nursing students and a second phase using the PhotoVoice tool SHOWED mnemonic method followed by discussion groups with second-year nursing students.

Results:

Three themes emerged: (1) hope tinged with fear; (2) too much information generating fear, uncertainty, and mistrust; and (3) leaders without recognition or voice.

Conclusion:

The results inform the body of knowledge in nursing science and enhance changes in clinical practice by providing new insights regarding the perceptions of nursing students on vaccination and its management, highlighting the need to train future nurses in health literacy and new ways to interact with community members.

Evaluation of Dog Presence as a Therapeutic Classroom Intervention
Authors: Bultas Margaret W. , Rittiwong Tanapa
Published: June 2023

Background:

The American Association of Colleges of Nursing has called on nurse educators to increase mental health support for nursing students. Animal visit programs reduce stress, anxiety, and negative mental health feelings; however, most are intermittent and occasional. This pilot study explored the feasibility, acceptability, and outcomes of integrating a therapy dog into the classroom.

Method:

This pretest-posttest, two-group design study included 67 baccalaureate nursing students. Two sections of a course were taught: one section included a therapy dog and one section did not.

Results:

At the end of the course, participants in the intervention group showed improvement in stress, anxiety, and happiness, whereas participants in the control group did not demonstrate any improvement. Students reported positive feelings and benefits from the presence of the therapy dog.

Conclusion:

Integrating a trained therapy dog into the classroom is both feasible and acceptable, with students identifying positively with the experience.

Radiation Injuries: Acute Radiation Syndrome in Children
Authors: Feldman Robert J. , Kazzi Ziad , Walter Frank G.
Published: June 2023

The conflict in Ukraine has raised the specter of radiological and nuclear incidents, including fighting at the Zaporizhzhia nuclear plant, the largest nuclear powerplant in Europe; concerns that a radiological dispersion device (“dirty bomb”) may be used; and threats to deploy tactical nuclear weapons. Children are more susceptible than adults to immediate and delayed radiation health effects. This article reviews the diagnosis and treatment of acute radiation syndrome. Although definitive treatment of radiation injuries should involve consultation with specialists, nonspecialists should learn to recognize the distinctive signs of radiation injury and make an initial assessment of severity of exposure.

Part 2: The Pediatric Hazards of Art Materials
Authors: Hinkamp David , McCann Michael
Published: June 2023

Children can encounter art materials that contain hazardous substances at school, in the home, and during outside activities. Hazardous substances can be found in both art materials that are made to be used by children and art materials used by adults. Some of these materials can be severe irritants, allergens, carcinogens, or other chronic disease hazards. Many of the most frequently used and potentially most hazardous materials are found in the categories of solvents, pigments, and adhesives. Selected members of these categories and where they may be found in common art materials are briefly discussed. Preventive techniques that specifically address the potential hazards of each category are included.

2.5D cascaded context-based network for liver and tumor segmentation from CT images
Authors: Bi Rongrong , Guo Liang , Yang Botao , Wang Jinke , Shi Changfa
Published: June 2023

The existing 2D/3D strategies still have limitations in human liver and tumor segmentation efficiency. Therefore, this paper proposes a 2.5D network combing cascaded context module (CCM) and Ladder Atrous Spatial Pyramid Pooling (L-ASPP), named CCLNet, for automatic liver and tumor segmentation from CT. First, we utilize the 2.5D mode to improve the training efficiency; Second, we employ the ResNet-34 as the encoder to enhance the segmentation accuracy. Third, the L-ASPP module is used to enlarge the receptive field. Finally, the CCM captures more local and global feature information. We experimented on the LiTS17 and 3DIRCADb datasets. Experimental results prove that the method skillfully balances accuracy and cost, thus having good prospects in liver and liver segmentation in clinical assistance.
Exponential stability of Cohen-Grossberg neural networks with multiple time-varying delays and distributed delays
Authors: Zhou Qinghua , Wan Li , Wang Hongshan , Fu Hongbo , Zhang Qunjiao
Published: June 2023

Maybe because Cohen-Grossberg neural networks with multiple time-varying delays and distributed delays cannot be converted into the vector-matrix forms, the stability results of such networks are relatively few and the stability conditions in the linear matrix inequality forms have not been established. So this paper investigates the exponential stability of the networks and gives the sufficient condition in the linear matrix inequality forms. Two examples are provided to demonstrate the effectiveness of the theoretical results.
The Impact of Mobile Application-Assisted Instruction on Intrinsic Motivation and Sports Nutrition Knowledge: The Case of Blended Learning
Authors: Ajlouni Aseel O. , AlKasasbeh Walaa Jumah , Al-Shara'h Arene , Ibrahim Amal
Published: June 2023

Abstract— In the physical education literature, E-learning in terms of online or blended learning has been lacking and facing several challenges which highlighted a need to conduct more research to investigate modern instruction in the context of physical education. This study is one of the few to determine the impact of Mobile Application-Assisted Instruction (MAAI) on intrinsic motivation and sports nutrition knowledge in a blended learning setting. The “KI-coach” app has been used as a state of an art mobile application based on artificial intelligence. This study adopted quasi experimental approach. Students were randomly assigned into a control group (n=25) that received the convolutional instruction method and an experimental group (n=25) that received MAAI. Study groups adopted a blended learning approach. Measures of intrinsic motivation and sports nutrition knowledge were administered to both groups before and after teaching the nutrition and physical performance course. The ANCOVA analysis revealed a statistically significant difference between the mean scores of the two groups on intrinsic motivation and sports nutrition knowledge. These findings indicated that using MAAI in blended learning promoted the development of intrinsic motivation and enhanced sports nutrition knowledge among physical education students. These findings encourage the decision-makers at the Ministry of higher education and physical education instructors to improve blended learning instruction and practice.
Exploring the Relationship between Participant Role and Collaborative Quality in Online Collaborative Discussions
Authors: Mi Huichao , Zhang Qiaorong , Zheng Yafeng
Published: June 2023

The exploration of the role concept has become an important perspective for analyzing and promoting computer-supported collaborative learning (CSCL). Understanding the relationships between individual participation roles and collaborative performance is of great significance to the research of collaborative learning theory, pedagogy and technology. However, few empirical studies investigated the individual participation roles in collaborative discussions and the impact of participation role configuration on group performance. Based on the interactive content of learners in collaborative discussions, this research uses machine learning methods to automatically identify learners’ participating roles. Through cluster analysis, five different roles are identified: leader, problem solver, coordinator, marginal learners and learners with difficulties. Furthermore, this research explores the relationships between individual participation roles and group collaboration quality. The results show that groups with different collaboration performances have different role compositions, and the roles of leader, problem solver and coordinator have significant positive effects on collaboration performance. Learners with difficulties have a negative impact on collaboration performance.

Bring-Your-Own-Device (BYOD) is a phenomenon whereby an employee brings their own computing devices to work with them and use them in addition to or instead of company-supplied devices. BYOD helps organization to cut cost and improve the utilization of organizational resources. However, the impacts and phenomenon of BYOD is still unknown and scarcely discuss within the body of knowledge; warrant for further exploration of the topic. Therefore, the purpose of this paper is to develop and validate an instrument to measure BYOD and its productivity. The research went through various empirical stages. Based on other studies, a list of predictors and dependent variables was adopted. Based on the variables that have been identified, a pilot instrument was created in the second step. Third, an expert review process was used to validate the instrument. The face validity and reliability investigation of possible respondents was completed. As a result, a reliable instrument with six variables and thirty items was created to measures BYOD and productivity in the context of universities students in Malaysia.
Examining the Factors Impacting Integrated Service Delivery in Leprosy Elimination Programs in Bihar
Authors: Kumar Vikash , Cheng Suk Yin Caroline
Published: June 2023

The disease control program is critical to the agenda of social justice. A generalist approach to the disease control program involves understanding its complexity and prevention from various perspectives, including ecological theory. The integration of the disease control program into the existing healthcare delivery system has been advocated over many decades, with an emphasis on the medical model of disease control. Integration has been widely considered as a means to achieve an effective and efficient health system. This approach has been widely adopted in low-middle-income countries to integrate vertical programs such as leprosy, malaria, HIV/AIDs, and others. However, studies suggest that there is a lack of evidence about the effectiveness of health system integration. The available evidence shows that integration of the health system can have a mixed, negative, or no impact on the health system. This growing enthusiasm toward health system integration is primarily based on the perceived benefits of an integrated approach. This discussion paper draws on the experience of the integration of the National Leprosy Elimination Program in India. It highlights the factors that affected the integration of leprosy programs in Bihar and also affected the pursuit of social justice for people who have been marginalized in our modern world.

Cities are crucial carriers of economic prosperity and social development. With the approaching Society 5.0, the digital twin city has become the mainstream model for the construction of new smart cities. Digital twins, along with the internet of things, fifth-generation wireless systems, and artificial intelligence technologies, offer great potential in the transformation of the current urban governance paradigm toward smart cities. This chapter will explore the imperative role of digital twin in accelerating digital transformation of smart cities. From the perspective of the overall policy, the industry, and application of the said technology, this chapter gives insight into the development trend of digital twin cities. Additionally, through case studies of the two most outstanding digital pilot regions in China, the chapter investigates the role of digital twin in accelerating digital transformation of smart cities such as the technical approaches on city information modeling (CIM) and building information modeling (BIM).
IoT Blockchains for Digital Twins
Authors: Wright Steven A.
Published: June 2023

Digital twins (DTs) have emerged as a critical concept in cyberspace infrastructure. DTs are virtual representations of physical things including model smart structures or environments, manufacturing processes, humans, and a variety of other things. The value provided by DTs relies on their fidelity in representation. Blockchains provide trust assurance mechanisms, particularly where multiple parties are involved. The expected life cycle operations of the IoT, blockchain, and DT need to be considered to develop economically useful blockchain digital twin (BDT) models. BDTs do not exist in isolation, but rather within a DT environment (DTE). A DTE may include multiple DTs of different objects to enable interactions between these objects to be evaluated in both virtual reality and mixed reality cases. To populate DTEs with multiple DTs requires industrialized tooling to support the rapid creation of DTs. The industrialization of DT creation requires frameworks, architectures, and standards to enable interoperability between DTs and DTEs.
The new era of anticoagulation: factor XI and XII inhibitors

Published: June 2023

The two last decades have witnessed a revolution in the field of anticoagulation, mainly due to the advent of direct anticoagulant with targeted action against single coagulation proteins. However, the residual risk of cardio- and cerebrovascular events, particularly in some critical settings, and the risk of major bleeding still represent unmet medical needs. Preclinical studies and experience from families with genetic deficiencies of factor XI or XII (FXI and FXII) allowed to identify these factors involved in the contact pathway of coagulation as potential targets for new anticoagulant approaches. To date, several pharmacological classes of FXI and FXII inhibitors have been developed, including antisense oligonucleotides, monoclonal antibodies, small molecules, natural inhibitors, and aptamers, and various molecules are currently under phase 2 or 3 clinical investigation. Particularly, promising results have been obtained in patients undergoing major orthopedic surgery, in those with end-stage kidney disease, atrial fibrillation and acute coronary syndrome. This review summarizes current knowledge on FXI and FXII inhibitors, with a particular focus on their pharmacological properties and potential clinical indications.

Background:

Metabolic syndrome (MetS) is rising in Indian population. MetS is less studied in Uttarakhand which has embraced modern culture and lifestyle. Hence, we aimed to study the prevalence and determinants of MetS.

Aim and Objectives:

(1) To determine the prevalence of MetS in the adult population (19–60 years) in urban areas of Rishikesh. (2) To determine the association of sociodemographic variables and risk factors with MetS.

Materials and Methods:

A community-based cross-sectional study was conducted in an urban area of Rishikesh. WHO steps instrument and protocol were used for the assessment of risk factors and measurements. Five milliliters of blood sample was collected for estimation of Fasting Blood sugar (FBS), triglycerides, and high-density lipoprotein. Sample size was calculated to be 478 (P = 34.3%, design effect = 2.0, drop out 5%, and relative precision = 18%). Data were analyzed using SPSS Version 20.0. Appropriate statistical tests for bivariate and multivariate analysis were done. P <0.05 was considered significant.

Results:

The prevalence of MetS in the urban area of Rishikesh is 38.2%. The prevalence of MetS in males and females is 33.9% and 40.5%, respectively.

Conclusions:

About 442 subjects had either one or more abnormal components of the MetS as classified by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. MetS prevalence was found to be higher in females than males. Prevalence was found higher in individuals belonging to the 41–50 years of age group.
