Detection of pharmaceuticals and their transformation products in seawaters using off-line solid phase extraction and liquid chromatography-high resolution mass spectrometry
Authors: Kalogeropoulou Aggeliki , Kosma Christina , Albanis Triantafyllos
Published: November 2024

Aim: Fast urbanization of free land, industrial progress, and improvement of human life quality, have led to increased consumption of different chemical substances recognized as emerging contaminants (ECs) that are chemicals posing potential risks to the environment and human health, but are not yet subjected to regulatory criteria. Pharmaceuticals consumed by humans are continuously discharged into aquatic environments through urban effluents and numerous classes of them have been widely detected in surface waters. We have to highlight that pharmaceuticals, deposited in the aquatic environment end up in human body through the consumption of marine organisms. Consequently, seawater can be considered as feed. Aim of the study is the development, optimization and validation of a multi-residue analytical method concerning the detection of pharmaceuticals in seawaters.
Methods: The present study describes the development of a highly selective and sensitive analytical method using solid phase extraction (SPE) followed by UHPLC-LTQ/Orbitrap MS for the determination of 18 frequently prescribed pharmaceuticals and 3 transformation products (TPs) in seawater. In order to optimize the extraction method different cartridge types were tested.
Results: Main results showed that the appropriate type of sorbent was concluded to be Oasis HLB, which presented the highest recoveries fluctuating between 61.6% and 118.8%, with a relative standard deviation below 4% and below 5%, for intra-day and inter-day precision, respectively. Limits of detection (LODs) ranged from 0.3 ng L–1 for venlafaxine to 9.8 ng L–1 for oxolinic acid, and the limits of quantification (LOQs) ranged from 1.2 ng L–1 for carbamazepine to 26.4 ng L–1 for oxolinic acid, while in all cases, the linearity, as measured by the correlation coefficient, was greater than 0.991 and ranged within the method’s quantification limit for each chemical and 1,000 ng L–1.
Conclusions: Concerning the conclusions positive detections were found in the seawater samples for oxytetracycline, sulfadiazine, caffeine, paracetamol, and trimethoprim.

Authors: Muruga Kirathimo , Iveta Ludviga
Published: November 2024

Physician dual practice, a global phenomenon involving simultaneous employment in both public and private healthcare sectors, is a topic of increasing interest. This research aimed to understand the outcomes of medical practitioners’ dual practice and their influence on doctors’ performance in Kenya. The study, which applied a survey design, targeted general medical practitioners practicing dual practice in Kenya. Dual Practice practitioners/medical practitioners were reached through semi-structured questionnaires (n=347). The quantitative data was analyzed using descriptive and inferential statistics using structural equation modeling (PLS-SEM) and SmartPLS4 software. The findings reveal the intricate nature of dual practice and identify factors that positively contribute to medical practitioners` performance, particularly knowledge spillover and career development. These insights directly affect healthcare policies in Kenya, providing practical guidance on enhancing performance and motivation among dual practitioners in the public healthcare system. The findings would help develop a further monitoring mechanism for the levels of Dual Practice and its causal factors in Kenya. From a theoretical perspective, the findings introduce knowledge spillover as a valuable resource that originates outside the organization in the context of the Job Demand-Resources (JD-R) Model, thereby contributing to the academic discourse on healthcare management.
How the Variance-to-Mean Ratio Behaves in Relation to the Basic Principles for Inequality Measures
Authors: Santos Carla
Published: November 2024

The phenomenon of inequality occurs when resources, opportunities, or other attributes are distributed unequally among the elements of a set. Although the literature on inequality focuses heavily on income inequality, inequality encompasses economic, social, and spatial dimensions, being relevant in different fields of society. When addressing inequality, the measure that immediately appears as a candidate for evaluating this inequality is the Gini index, however, there are several circumstances in which other measures of inequality are more appropriate, or in which the information provided by the Gini index is insufficient to adequately characterize or compare inequality. Considering that, in certain situations, the Variance-to-Mean Ratio and the Gini Index appear as viable alternatives to measure inequality, we are interested in analyzing the Variance-to-Mean Ratio regarding its compliance with the four basic criteria for inequality measures, adopting a formal and axiomatic approach. We conclude that the Variance-to-Mean Ratio does not meet all these requirements.

Authors: Wang Yujiao , Laochankham Sirisak , Yang Wei
Published: November 2024

Educational policy evaluation is a factual and valuable judgment of the educational policy process and its effects, and educational policy evaluation criteria determine the direction and effects of educational policy evaluation. At present, there is a lack of research results on the evaluation of education policies based on OECD/DAC evaluation criteria in China, and the construction of theories on the evaluation of education policies is still weak. Most scholars are limited to analyzing basic education data released by the OECD or focusing on basic theoretical research on education policy evaluation. This study adopts qualitative research and collects data through in-depth interviews and focus group discussions, consults experts in relevant educational institutions and other fields many times, takes into account China’s regional differences and the reality of educational development, and adopts the OECD/DAC evaluation criteria that are widely recognized in the international arena, in combination with the “Measures for Supervisory and Evaluation of Quality and Balanced Development of Compulsory Education in County Areas” of the Ministry of Education of China, and constructs a scientifically reasonable evaluation criteria system of the policy of balanced development of compulsory education in counties in China. The results show that five groups of people, including government officials, school teachers, students’ parents, experts, and social stakeholders, have a high degree of acceptance of the evaluation criteria and believe that the four criteria of effectiveness and relevance, coherence, and impact in the OECD/DAC evaluation criteria are the core criteria for evaluating China’s policy of balanced development of compulsory education (referred to as BDCE). The results of this study show that the evaluation criteria system is suitable for evaluating the BDCE policy in China, and provides a useful reference for the evaluation of the BDCE policy in China.
Geomorphological signatures of Neotectonic deformations and Paleo-earthquake study in Jorhat and Mokokchung districts of Assam and Nagaland, India
Authors: Kour Gurpreet , Bezbaruah Devojit
Published: November 2024

Tectonics plays an important role in landscape evolution, the records of which are preserved in geomorphic features. Evidence of past earthquakes is preserved in sediments in the formof liquefaction structures. The study of active tectonics and paleo-earthquakes is carried out in the Jorhat and Mokokchung districts of Assam and Nagaland respectively. The evidence of ongoing tectonic activity in the study area is the presence of irregular water bodies along Naga Thrust, the presence of different levels of terraces, river channel shifting, avulsion of meander belt, presence of pressure ridge, and variation in sinuosity of river. In the study area, the primary ground ruptures are not identified as the last Great Assam Earthquake was experienced in 1950. It is already 72 years since then so the records of primary ruptures if any in the past are obliterated by erosion and deposition of sediments. Secondary ground failure in the form of liquefaction structures with sand dykes, seismites, and hydroplastic deformation of sediments are encountered in the deposits along the bank of Bhogdoi River at Koleapani Tea Garden, Pukhuria, Gongapur and Hatigarh.

SARS-CoV-2 causing COVID-19, started spreading its roots across the world in December 2019. Its severity and death numbers created a panic that flooded social media with various myths and misinformation. Our study included two parts, survey based research, and a bibliographic review. The survey based research focused on the exposure and beliefs of individuals about the myths and misinformation since the beginning of the COVID 19 pandemic. Secondly, the aim of the bibliographic review was to focus on the various types of social media platforms, studies on myths/misinformation, and their major highlights. A data-driven survey methodology was employed for the analysis of individual beliefs regarding myths and misinformation associated with COVID-19 using Google forms. Publications were searched on PubMed®, APA PsycNet® (PsycArticles), and Nature Portfolio and were analyzed in the bibliographic review. From the results of the survey, it can be concluded that in the situation of the COVID-19 pandemic, the society held a mixture of various individual perceptions or beliefs. Certain myths/misinformation has gained clarification among people from 2019 to 2022 and some new updates are leading to new myths/misinformation. The present study and bibliographic review highlight that different types of information on COVID-19 myths have been reported from the period 2020 to 2022 and how they are different/similar.

The article analyzes the importance of emotional intelligence in personal psychology and how it plays a role in overcoming the negative consequences of neuroticism.
SOME THEORETICAL AND PRACTICAL ISSUES ON THE CONSTRUCTION AND DEVELOPMENT OF URBAN CULTURAL COMMUNITIES IN VIETNAM TODAY
Authors: Nguyen Ngoc Tho
Published: November 2024

Rapid urbanization is one of the positive results of Vietnam’s current industrial and service economic development. The success of innovative economic development policies has driven strong growth in many urban areas of the country in recent decades. The transition from traditional agrarian rural life to an urban environment will certainly not be without many disruptions and even problems; therefore, Vietnam needs to establish appropriate community cultural model(s) in the urban environment as a guide for the gradual development of urban communities in the coming decades. This article analyzes the theoretical foundations of urban community culture in the contemporary Vietnamese context from the interdisciplinary perspective between cultural studies, urban studies, and other disciplines, draws on the experience of some typical cases in the region and around the world, and proposes a scientific and practical basis for the development of community culture in urban areas in Vietnam. It can be said that building a new urban community culture in Vietnam today requires a multidimensional approach, including two basic perspectives, a constructivist approach and a cognitive approach, to ensure the two main objectives of (1) creating a suitable and effective cultural environment for urban communities and (2) enhancing the sense of responsibility for participating in cultural creation and building an urban cultural flow that protects, inherits traditions, and fully conforms to civilized and modern standards.

A key step in building regulatory acceptance of alternative or non-animal test methods has long been the use of interlaboratory comparisons or round-robins (RRs), in which a common test material and standard operating procedure is provided to all participants, who measure the specific endpoint and return their data for statistical comparison to demonstrate the reproducibility of the method. While there is currently no standard approach for the comparison of modelling approaches, consensus modelling is emerging as a “modelling equivalent” of a RR. We demonstrate here a novel approach to evaluate the performance of different models for the same endpoint (nanomaterials’ zeta potential) trained using a common dataset, through generation of a consensus model, leading to increased confidence in the model predictions and underlying models. Using a publicly available dataset, four research groups (NovaMechanics Ltd. (NovaM)-Cyprus, National Technical University of Athens (NTUA)-Greece, QSAR Lab Ltd.-Poland, and DTC Lab-India) built five distinct machine learning (ML) models for the in silico prediction of the zeta potential of metal and metal oxide-nanomaterials (NMs) in aqueous media. The individual models were integrated into a consensus modelling scheme, enhancing their predictive accuracy and reducing their biases. The consensus models outperform the individual models, resulting in more reliable predictions. We propose this approach as a valuable method for increasing the validity of nanoinformatics models and driving regulatory acceptance of in silico new approach methodologies for the use within an “Integrated Approach to Testing and Assessment” (IATA) for risk assessment of NMs.

Published: November 2024

Selectivity in radical chain oligomerizations involving [1.1.1]propellane – i.e., to make [n]staffanes – has been notoriously challenging to control when n > 1 is desired. Herein, we report selective syntheses of SF5- and CF3SF4-containing [2]staffanes from SF5Cl and CF3SF4Cl, demonstrating cases whereby oligomerization is preferentially truncated after incorporation of two bicyclopentane (BCP) units. Synthetic and computational studies suggest this phenomenon can be attributed to alternating radical polarity matching. In addition, single-crystal X-ray diffraction (SC-XRD) data reveal structurally interesting features of the CF3SF4-containing [2]staffane in the solid state.

Authors: Wahyuningsih Erfiana , Galiano S Difano
Published: November 2024

The hospitality industry is known for its high energy use. The operation of many 24-hour facilities raises energy demand. The Minister of Culture and Tourism's Decree Number KM.03/HK.001/MKP.02 requires that the quality of services and facilities be examined. Air conditioners, water heaters, exercise facilities, and conference rooms all require reliable electrical systems. Energy efficiency is essential, especially for facilities that use a lot of power, including heat pump water heaters in restrooms and fitness center equipment. Hotel A in Jakarta Tanah Abang, which has not yet implemented energy conservation measures, requires energy management systems and audits to improve efficiency. The Energy Consumption Intensity (IKE) is the amount of energy used by a building to increase a conditioned area over a month or a year. The study's goal is to determine IKE values for the period February 2024 to June 2024, as well as energy consumption patterns in accordance with the standards. This study included data collecting, interviews, observations, and direct measurements to determine the energy usage of each month and the entire facility. The IKE calculation approach yielded the following findings for each month: February 5,069701417 kWh/m2/month, March 5,235947214 kWh/m2, April 5,009387155 kWh (m2), May 6,335605837 kWh(m2), and June 6,127963403 kWh/m2. With scores ranging from 5 to 6,3 performance energy consumption, electricity falls into the "Very Efficient" category, eliminating the need for energy savings that could disrupt hotel operations.

Eventos climáticos extremos e fatores relacionados à transição para uma economia de baixo carbono podem originar eventos de risco capazes de gerar impactos negativos sobre o financiamento do desenvolvimento mediante a afetação do balanço de instituições financeiras e da estabilidade do sistema financeiro. O Bank for International Settlements (BIS) elabora recomendações internacionais e o Banco Central do Brasil (BCB) desenvolve normas e métricas de regulação financeira no âmbito da economia brasileira, inclusive quanto à exposição das instituições financeiras a riscos originados por eventos climáticos. Essa nova dimensão da regulação, ao determinar um tratamento mais formalizado e sofisticado dos riscos relacionados ao clima, constitui-se como fator relevante da estratégia, dos modelos de negócios das instituições financeiras, da classificação de riscos dos projetos, da precificação de ativos e, consequentemente, produz repercussões nas condições de financiamento do desenvolvimento.

An effective numerical algorithm for coupled systems of Emden-Fowler equations via shifted airfoil functions of the first kind
Authors: Izadi Mohammad , Roul Pradip
Published: November 2024

The present paper deals with the designation of a new efficient numerical scheme for numerical solution of a class of coupled systems of Emden-Fowler equations describing several processes in applied sciences and technology. This method combines the shifted version of airfoil functions of the first kind (AFFK) and quasilinearization technique. More specifically, the quasilinearization technique is first applied to the original problem and the shifted AFFK (SAFFK) collocation matrix technique is then constructed for obtaining the solution of resulting family of submodels. We derive the error bound and analyze the convergence properties of the SAFFK. Computational and experimental simulations are carried out to describe the applicability and accuracy of the new technique. To show the benefit of the new approach, the computed numerical outcomes are compared with those results obtained via the Bernoulli and Haar wavelets collocation methods. It is evident from the numerical illustrations that the new developed scheme is superior to the existing available ones. The elapsed CPU time of the proposed method is provided.
Mirroring and nonlinear perturbation of a circuit's system with multiple attractors
Authors: Doungmo Goufo Emile Franc
Published: November 2024

We infix the duality-symmetric and the mirror symmetry conversion processes into a dynamical system representing an electric circuit diagram with three input (or output) as shown in Figure 2. Hence, a new non-linear variable order initial value problem is obtained and solved using the Haar wavelet numerical method (HWNM). Error, stability and entropy analyzes show the reliability of the method. Numerical simulations are then implemented and show for the new system, existence of various attractors’ types (point attractors (PAs), limit cycles, strange attractors (SAs), double attractor (DA), coexisting attractors (CoAs)) with their mirror reflections. Both are in a symmetrical structure in which they face each other, separated by a changing symmetry line and exhibiting similar properties. The circuit implementation using a Field Programmable Gate Array (FPGA) is performed and concur with the expected results.
Investigating the Potential of LS 5039 as a Triple System Using Fermi-LAT Data
Authors: Zeng Lujun , Zhang Mengqing , Ren Chongyang , Zhang Pengfei , Yan Jingzhi
Published: November 2024

LS 5039 is one of a handful of γ-ray binary systems in the milky Way, comprising a pulsar and a massive O-type companion star with an orbital period of 3.9 days. Recently, we conducted a data analysis using approximately 16 yr of Fermi Large Area Telescope observations, spanning from 2008 August 4 to 2024 July 8. In our timing analysis, we discovered two new periodic signals with frequencies higher and lower than the known orbital period. The higher-frequency signal has a period of 3.63819 days with a 7.1σ confidence level, while the lower-frequency signal has a period of 4.21654 days with a 6.3σ confidence level. Additionally, in data from the High Energy Stereoscopic System of Cherenkov telescopes, two potential signals are found with periods similar to the two newly discovered ones. Considering that these two signals fall within the same frequency interval as the orbital period, we suggest the possibility of a third body orbiting the barycenter of the LS 5039 binary system, with the new periodic signals arising from specific frequency combinations of the two orbital periods.

We present the spectroscopy of CWISE J151044.74−524923.5, a wide low-mass companion to the nearby (~24.7 pc) L 262-74 system. Analyzing the near-infrared spectrum obtained with the TripleSpec4 spectrograph on the Southern Astrophysical Research Telescope, we confirm that it is a brown dwarf with unusually red colors. Although this redness can be characteristic of young, low-gravity brown dwarfs, we assess that this object is likely a field object being reddened by factors other than youth. We assign it a spectral type of L6 (pec). Finally, we highlight new TESS data that provide further evidence of the multiplicity of the central system.
Model for sustainable carbon emission reduction energy development and smart grid technology strategy
Authors: Xiang Kangli , Chen Keren , Chen Simin , Chen Wanqing , Chen Jinyu
Published: November 2024

In the context of sustainable energy development to reduce carbon emissions, the application of new energy sources and smart grid technologies in power systems is becoming more widespread. However, current research results on power system technology strategies for carbon emission reduction are not satisfactory. To address this problem, a model for optimal power system operation and scheduling based on the prediction error mechanism and synthetic fuel technology is proposed. The model used the carbon trading mechanism to further reduce carbon emissions and the carnivorous plant algorithm to optimize the scheduling strategy. The results indicate that the model demonstrates significant advantages in terms of carbon emission, total operating cost, prediction accuracy, and energy utilization efficiency, respectively, at 60.8 kg, 2517.5 yuan, 96.5%, and 90.2%, indicating that it utilizes energy more fully and helps to enhance the overall energy efficiency of the system. The calculation time of the optimized power system was only 12.5 s, the stability was as high as 98.7%, and the satisfaction rate was 95.6% in terms of user satisfaction. Compared to other contemporary designs, the proposed model can successfully reduce the system's carbon emissions while increasing energy efficiency. The model has positive implications for smart grid and sustainable development.
On maximum residual block Kaczmarz method for solving large consistent linear systems
Authors: Sun Wen-Ning , Qin Mei
Published: November 2024

In this paper, we propose two block variants of the Kaczmarz method for solving large-scale consistent linear equations $ Ax = b $. The first method, named the maximum residual block Kaczmarz (denoted as MRBK) method, first partitions the coefficient matrix, and then captures the largest block in the residual vector during each block iteration to ensure that it is eliminated first. Simultaneously, in order to avoid the pseudo-inverse calculation of the MRBK method during block iteration and improve the convergence speed, we further propose the maximum residual average block Kaczmarz method. This method completes the iterative process by projecting the current solution vector onto each row of the constrained subset of the matrix $ A $ and averaging it with different extrapolation steps. We analyze and prove the deterministic convergence of both methods. Numerical experiments validate our theory and show that our proposed methods are superior to some other block Kaczmarz methods.

Objectives: This cross-sectional study investigated the association between the utilization of 8 antenatal care (ANC) visits and delivery in a healthcare institution in the Philippines, using data from the 2022 National Demographic and Health Survey.Methods: A sample of women who had given birth within the past 3 years was selected for analysis (n=4452). The association between ANC utilization and institutional delivery was assessed using logistic regression models, covariates by relevant socio-demographic factors, and childbirth history.Results: We found that 97.2% of respondents who completed ANC opted for institutional delivery. A higher proportion of rural residents did not undergo institutional delivery than urban residents (12.9 vs. 6.9%). The group aged 20-24 years had the highest coverage (92.8%), and the group aged 40-44 years had the lowest. Higher education levels, employment, and greater wealth were associated with higher institutional delivery rates. Divorced or widowed mothers (85.1%) and grand multiparous mothers had lower rates than other groups. Multivariable logistic regression analysis showed a significant positive association between ANC utilization and institutional deliveries after adjusting for covariates (adjusted odds ratio, 2.486; 95% confidence interval, 2.485 to 2.487; p<0.001).Conclusions: ANC visits were associated with deliveries in institutions in the Philippines. Policymakers should promote ANC by ensuring 8 World Health Organization-recommended visits, strengthening programs, conducting community outreach, addressing access barriers, and integrating maternal health services to increase institutional births and improve maternal and infant health.

Los desafíos culturales nunca han dejado de estar en el centro de la existencia humana. Con los acontecimientos adversos que han sacudido a la humanidad históricamente, algunos hábitos y lugares culturales han ido desapareciendo mientras otros han persistido. De ahí la urgencia de salvaguardar lo que queda del patrimonio cultural de cada pueblo. Este estudio explora los mecanismos de la patrimonialización y la salvaguardia del patrimonio cultural camerunés, así como las sinuosidades de la cultura bamileke. En el contexto camerunés, la tarea de patrimonialización no resulta fácil, dado la diversidad étnica y cultural del país. Por tratarse de un proceso a la vez sociocultural y político, la compilación de los elementos patrimoniales ocupa a una fuerza laboral diversa. En esta área geográfica, el pueblo Bamileke es reconocido como uno que ilumina el paisaje cultural por su diversidad cultural y apego a sus valores tradicionales. Orgulloso de sus ritos, sus jefaturas tradicionales, sus bosques sagrados y sus reyes con poderes místicos, el pueblo Bamileke cree en sus antepasados, intermediarios entre los muertos y los vivos, y se rinde culto a los cráneos de sus difuntos.
Chems Palace : le roman écopoétique d’Ali Bécheur
Authors: Miled Samar
Published: November 2024

La particularité de l’écriture du romancier tunisien Ali Bécheur réside dans la dimension poétique de ses écrits. Ses romans, bien que répondant aux impératifs formels du genre romanesque, défient la loi du genre littéraire lui-même, lorsque certains paragraphes se donnent à lire sous forme de poésie. Une poésie libre, libérée des contraintes formelles, émerge des tréfonds de l’âme du romancier-poète, et souvent, ce changement de ton est là pour marquer une émotion en lien avec les changements qui touchent les traditions tunisiennes. Dans Chems Palace, roman publié en 2014, Bécheur a recours à la prose poétique pour contrecarrer un matérialisme croissant qui menace de plus en plus le cadre naturel dans lequel évoluent les personnages. Le narrateur observe avec amertume la crise environnementale qui s’annonce dans les régions arides du pays, à savoir les régions du Sud, à cause de l’expansion des sites touristiques qui se développent dans l’irrespect total de la Nature. En réponse à cette menace qui guette les gens du Sud dont la vie dépend de la Palmeraie et de ses richesses, Ali Bécheur écrit pour rendre hommage à ces derniers, et il se sert de l’écriture pour mettre en lumière les pratiques culturelles des villageois, et leur respect pour l’environnement. En ce sens, on s’intéressera en particulier à la façon dont Ali Bécheur nous présente sa vision du « Vivre-Ensemble » incluant cette fois la Nature comme partie intégrante du cycle de la vie. Par ailleurs, une prose éco-poétique s’impose dans le roman et vient marquer la rupture avec un monde hyper-matériel. De ce fait, ce travail explore le lyrisme comme forme de résistance, et notre analyse porte essentiellement sur l’écriture poétique comme expression du souci écologique.
Mise en perspective de L’origine de la géométrie : Hubert Damisch et la postérité de Husserl en philosophie de l’art
Authors: Colmart Jules
Published: November 2024

Les réflexions de Husserl dans L’origine de la géométrie ont connu une réception qui excède le cadre de la philosophie des sciences ou de l’histoire. On peut, à partir d’une lecture des cours de Merleau-Ponty sur l’institution (1954-1955) et le Beilage III (1960-1961), de l’« Introduction » de Derrida à sa traduction (1961), mais surtout de L’origine de la perspective (1987) de l’historien d’art et philosophe Hubert Damisch, saisir toute l’importance de sa théorie de l’historicité et des idéalités abstraites pour l’esthétique et la philosophie de l’art en France. Cet article prend pour exemple le cas de la perspective, sujet à controverse pour les historiens d’art. Damisch dans L’origine de la perspective (1987), un ouvrage conçu explicitement comme un « déplacement » de Husserl, tente de résoudre de façon originale le problème de l’historicité de l’art à partir de la phénoménologie. De surcroît, sa description des expériences de Brunelleschi comme origine du paradigme perspectif, à la croisée de l’optique, de la géométrie et de la peinture invite aussi bien à étoffer les concepts d’origine et de réactivation à partir de ceux de répétition d’origine (voire de Renaissance) qu’à repenser la relation husserlienne entre les idéalités sensibles et les idéalités abstraites : que deviennent en effet l’histoire de la pensée et le partage entre l’expérience sensible et la géométrie si s’insère un tiers-milieu, si le dessin et la peinture peuvent opérer à eux seuls un travail d’idéalisation objective ?

L'objectif de cet article est d'analyser les perceptions des communautés locales vis-à-vis du site Ramsar du complexe lagunaire de Keta Lagoon et d'évaluer les principales menaces environnementales pesant sur ces écosystèmes. La méthode de recherche a combiné des entretiens semi-structurés avec des groupes de discussion pour recueillir des données qualitatives approfondies, représentatives des perceptions et des dynamiques locales, couvrant l'ensemble des six districts du complexe lagunaire de Keta Lagoon. Les résultats montrent que les principales menaces identifiées par les communautés locales autour du complexe lagunaire de Keta Lagoon sont la surexploitation des ressources naturelles (mentionnée par 70 % des répondants), le blocage des canaux, la salinisation et les perturbations climatiques. Ces menaces aggravent la dépendance des communautés à leur environnement et ont entrainé une dégradation importante de leurs conditions de vie au cours des 10 à 20 dernières années. Environ 46 % des personnes interviewées ont une connaissance insuffisante ou inexistante du site Ramsar, tandis que 42 % en ont une bonne connaissance. Ce dernier point remet en question l'idée courante selon laquelle les acteurs locaux ont une connaissance approfondie de leur aire protégée et un engagement naturel envers la protection de l'environnement. Malgré cette lacune, il existe une volonté manifeste d'adhésion aux lois de protection environnementale parmi les communautés locales. Ce diagnostic a conduit à la mise à jour du plan d'aménagement 2023-2032 du complexe lagunaire de Keta Lagoon, le premier depuis 1999, visant à restaurer les écosystèmes, atténuer les menaces identifiées, et améliorer les conditions de vie des communautés locales en renforçant leur implication dans la gestion durable du site.
The Role of Intercultural Competence in Effective Cross-Border Collaboration Among Higher Education Institutions
Authors: Vaishnav Pankaj Bhanudas
Published: November 2024

Intercultural competence plays a vital role in enhancing cross-border collaboration among higher education institutions. It includes the ability to understand, communicate, and interact effectively with people from diverse cultural backgrounds. At Higher Educational level, it allows students to develop mutual respect for each other and significantly reduces any possibility of misunderstanding. These days, student and teacher exchange program, joint research projects, partnership in any educational program are benefitted from interculturally competent experts. Leaving behind cultural difference, such an initiative puts forth diverse perspective and create healthy atmosphere. Concentrated and systematic efforts are needed to develop intercultural competence and strengthen cross-border collaboration further. Higher educational institutions should prioritize it to get global exposure and achieve academic excellence. If staff and students are trained properly, interconnection of people coming from diverse background can make teaching and learning, a more fruitful activity.
Current Trends in AI Ethics for Software as a Medical Device (SaMD)
Authors: Vu Thanh , Throne Robin
Published: November 2024

Past scholarship has noted the growing concerns and complex challenges surrounding the emergent use of ubiquitous digital technologies in medicine and healthcare, including artificial intelligence (AI) and machine learning (ML). The scholarship has also noted the challenges that human research protection programs (HRPP) and institutional review boards (IRB) have faced in an evolving regulatory climate to review human subjects research involving AI and ML for medical devices. This chapter presents the results of a trends analysis of the current scholarship surrounding compliance trends for AI ethics specific to the use of protected health information (PHI) and compliance trends specifically surrounding AI ethics in software as a medical device (SaMD) for new investigators seeking IRB review for AI/ML research activities. The trends offered in the current scholarship also present many opportunities for policy implications needed to assure ethical oversight for the protection of human subjects in research involving AI/ML for IRBs and HRPPs to review this research.
The Belmont Report
Authors: Tariq Muhammad Usman
Published: November 2024

This chapter explores the Belmont Report, a cornerstone in the ethics of human subject research. It details the report's historical development, emphasizing the three pivotal principles: Respect for People, Beneficence, and Justice. These principles advocate for autonomy through informed consent, the minimization of harm coupled with the maximization of benefits, and fairness in research burden distribution. The chapter discusses the operational challenges in applying these principles across modern research settings and examines the evolving role of Institutional Review Boards (IRBs) in enforcing these standards. Additionally, it addresses the limitations of the Belmont Report in contemporary issues like digital data privacy and the globalization of research practices. The chapter concludes by emphasizing the necessity for dynamic ethical frameworks that adapt to ongoing technological and societal shifts, urging continued ethical vigilance in human subject research.

This chapter presents the best practices used by institutional review boards (IRBs) and human research protections programs (HRPPs) to prepare online graduate student investigators for human research protections specific to research within online graduate degree programs or where research supervisors are not proximal to graduate student investigators and their research protocols. In recent years, advances in artificial intelligence (AI), machine learning (ML), and other data mining/scraping forms have adversely impacted individual privacy and the unintended sharing of personally identifiable information (PII). With this growth of ubiquitous digital technologies, such as AI, ML, and data mining/scraping, used across online graduate degree programs, specialized training and preparation are needed to best prepare graduate student researchers for human research protections involving data with PII.
