Une recherche-action en pédagogie de l’alternance : une autre façon de se trans-former
Authors: Poplimont Christine
Published: April 2022

La recherche dont il est question ici vise à tenter de comprendre dans quelle mesure des formateurs par alternance semblent ou non parvenir à intégrer les acquis d’une formation de formateurs axée sur les processus d’apprentissage mis en œuvre dans la pédagogie de l’alternance, à travers un dispositif qui les met eux-mêmes en situation d’apprentissage par alternance. Cette pédagogie vise à sortir du schéma classique de l’enseignement qui consiste à mettre l’apprenant en situation de consommation de savoirs. Apprendre consiste, dans ce cas à retenir, à enregistrer des savoirs. Nous nous trouvons là face à des personnes capables de réciter des cours mais pas du tout préparées à faire des liens entre les enseignements reçus et leur mise en application et leur questionnement. Au contraire, la pédagogie de l’alternance, balancement permanent entre récits d’expériences et apports théoriques permet à la fois d’interroger, mais aussi d’expérimenter de nouvelles pratiques. Cette distanciation provoquée entre posture et pratique est favorisée par une production écrite qui favoriserait selon le terme de G. Lerbet (1984) « une production de savoir », qui est à l’université la rédaction d’un mémoire de recherche ou d’une thèse. Les terrains d’observation sont deux groupes de master professionnel 2e année, de l’Université de Provence qui doivent rédiger un mémoire en fin d’année. En effet, il s’agit pour l’apprenant à travers cette production écrite de faire des liens, de relier des pôles, des idées apparemment opposées. De cette pédagogie de l’alternance peut naître une vision plus globale permettant d’appréhender un degré de complexité, d’entrelacement susceptible de favoriser une pensée critique.

Published: April 2022

Cybersecurity is becoming a national issue, and the average cost of a data breach is USD 3.9 billion. CEOs and business owners face the challenge of legal and regulatory compliance when it comes to protecting data against sophisticated cyber threats. The COVID-19 crisis has pushed organizations to quickly adopt digital technologies and shift to remote work models, which means more significant opportunities for hackers to target individuals and enterprises. The MENA region alone suffered from over 9000 new spam messages and advanced malware attacks last year, and criminals exploit psychological vulnerabilities that make victims susceptible to social engineering techniques. This chapter aims to present the latest findings and insights about security vulnerabilities in organizations and show some of the best practices in mitigating threats. The chapter will delve into the different modes of attacks, including tactics cybercriminals take advantage of and what enterprises can do to stay protected from them.

Authors: Elloumi Zitouna Imene
Published: April 2022

In the Tunisian context, and during the SARS_COV19 pandemic, the authors proposed to the Hospital Centers of the Ministry of Health in Tunisia as well as the Institut of Pasteur a set of e-health projects based on artificial intelligence. During the IT development process, they had many problems related to the processing of health data: insufficiency and lack of health data for the development of innovative and intelligent applications, the health system having no digitalization, the need for law application of personal health data even in the context of scientific research. Moreover, the risk of data leaks, non-compliance with the law and cyber attacks are increased by a greater use of personal devices, a common circulation of data, and sensitive computer systems that are becoming more accessible outside hospitals' networks. In this chapter, the authors present the process that has been applied to guarantee the protection of personal health data through three different projects and explain the steps for this process implementation.

Published: April 2022

Proximity tracing between individuals for detecting contact persons is seen by several disease control authorities as a key instrument during the COVID-19 crisis. To develop further the capabilities of infection monitoring and providing automated actionable intelligence, multi-domain data needs to be collected, aggregated, and analyzed. The fifth-generation technology standard for broadband cellular networks, the 5G system, can hereby act as a trusted platform for data collection from mobile applications and from the network itself, making use of its cloud native analytics and of its mass-scale alert system, both of which enable coverage of a maximum user population through standard cellular functions. This chapter provides a solution for disease monitoring and alerting using the potential of mobile telecommunication technology for the coupling of user tracking information with specific information on diseases. The authors explore how the 5G system, with its advanced analytics capabilities, can be used for such disease monitoring.

Published: April 2022

This chapter studies the component of stress among HCWs related to the COVID-19 pandemic and its influencing factors and interventions in preventing stress at work. Staff were interviewed using the job content questionnaire a validate version of Karasek model with 26 questions. Sociodemographic and stress variables were entered into correlation analysis to find the variables associated with occupational stress. The empiric results show in the first part that the component of occupational stress is essentially from low decision latitude and high psychological job demands. The empiric results show in the second part that certain sample characteristics have crucial impact on the Karasek score either positive or negative. Moreover, the healthcare staff are using multiple techniques and strategies to cope with the job strain during this pandemic, but only 11% are seeking professional support.
A Survey on COVID-19 Fake News Detection on Twitter
Authors: Boongasame Laor
Published: April 2022

As the COVID-19 pandemic spreads rapidly, a lot of fake news in social media has accompanied it. During such a time, fake news can lead to people being endangered. This means that the spread of misinformation in social media needs to be contained immediately. This chapter discusses techniques for detecting fake news. Existing research discusses techniques for detection of fake news, including classification, regression, and deep learning. There is little evidence, however, that researchers have approached fake news detection techniques on Twitter about COVID-19. The aim of this chapter is therefore to provide an overview technique for detecting fake news about COVID-19 on Twitter.

Challenges and Advantages of Implementing Blockchain Internet of Medical Things (B-IoMT) in 6G Networks
Authors: K. Murugan , R. Somasundaram , Thirugnanam Mythili , S. Pousia , U. Sakthi
Published: April 2022

The internet of things (IoT) has cleared the door for sophisticated functionalities to be introduced into the healthcare business. IoT systems handle a significant amount of data and require 6G network connectivity, power, and storage to convert it into useful information. The internet of medical things refers to the use of IoT-based internet-enabled medical devices in the healthcare business (IoMT). The lack of security standardization and energy-consuming cryptographic algorithms in man-in-the-middle attacks, session hijacking, and wireless encryption breaking are all possible security problems with IoMT. On the other hand, because of its decentralised nature, blockchain may be used to address IoT problems. The widespread adoption of decentralised blockchain technology in IoT has significantly reduced the danger of sensitive healthcare data being exposed. The authors combine blockchain technology with IoMT (B-IoMT) in this chapter to enable secure data transfer over a 6G network connection. The blockchain's security characteristics aid in achieving tamper-proof data transfer in IoMT.

Published: April 2022

From 2030 onward, 6G is a potential communication technology that will dominate the whole health sector. Finland was the first to start a 6G experiment in 2018. Second, in 2019, the US, South Korea, and China launched the 6G initiative. Japan has just announced a 6G research initiative for 2020. In addition, 6G has spawned a slew of new algorithms. It is now critical to begin the 6G project in order to avoid falling behind other countries. On the other hand, 5G communication technology has yet to be fully deployed globally, and B5G has yet to be created. 5G and B5G will have a number of disadvantages when it comes to revolutionizing current lifestyles, society, and industry. For example, due to the reduced data rate, holographic communication is not possible. As a result, now is the best moment to think about the future of 6G communication technology. It is also important to consider future healthcare in order to ensure the well-being of society's citizens. It will rule not just the health industry, but also a variety of other industries.

Authors: U. Surendar , Subramaniyan Senthilkumar , Johnson William , K. Umamaheswari , B. Nataraj , A. Rengarajan
Published: April 2022

This chapter presents a simple, metamaterial-loaded planar ring antenna for WLAN/WiMAX applications. The proposed antenna is equipped with two neutralization lines to improve performance in the desired operating bands. The use of neutralization lines as conducting strip allows the antenna to function at the upper resonance-3.5GHz and the incorporation of complementary split ring resonator at the rear of the substrate benefits in the antenna's compact size. Due to the incorporation of a quarter wave transformer with a semicircular ring construction, the ring antenna produces better dual-band response. The upper resonance 3.5GHz is obtained due to the combination of tuned semicircular ring and circular ring along with the conducting strip in the structure. The fabricated antenna is printed on FR4 substrate with dimensions 10×10×1.6 mm3. The simulated results are verified by experimenting the fabricated antenna. It offered 14.6% bandwidth in the lower resonance 2.4 GHz and 8.5% bandwidth at upper resonant frequency 3.5GHz with radiation characteristics suitable for the WLAN/WiMAX applications.
Concept of Temporal Pretopology for the Analysis for Structural Changes
Authors: Selmaoui-Folcher Nazha , Tokotoko Jannai , Gorohouna Samuel , Roi Laisa , Leschi Claire , Ris Catherine
Published: April 2022

Pretopology is a mathematical model developed from a weakening of the topological axiomatic. It was initially used in economic, social and biological sciences and next in pattern recognition and image analysis. More recently, it has been applied to the analysis of complex networks. Pretopology enables to work in a mathematical framework with weak properties, and its nonidempotent operator called pseudo-closure permits to implement iterative algorithms. It proposes a formalism that generalizes graph theory concepts and allows to model problems universally. In this paper, authors will extend this mathematical model to analyze complex data with spatiotemporal dimensions. Authors define the notion of a temporal pretopology based on a temporal function. They give an example of temporal function based on a binary relation, and construct a temporal pretopology. They define two new notions of temporal substructures which aim at representing evolution of substructures. They propose algorithms to extract these substructures. They experiment the proposition on 2 data and two economic real data.

Authors: Schild Erwan , Durantin Gautier , Lamirel Jean-Charles , Miconi Florian
Published: April 2022

Chatbots represent a promising tool to automate the processing of requests in a business context. However, despite major progress in natural language processing technologies, constructing a dataset deemed relevant by business experts is a manual, iterative and error-prone process. To assist these experts during modelling and labelling, the authors propose an active learning methodology coined Interactive Clustering. It relies on interactions between computer-guided segmentation of data in intents, and response-driven human annotations imposing constraints on clusters to improve relevance.This article applies Interactive Clustering on a realistic dataset, and measures the optimal settings required for relevant segmentation in a minimal number of annotations. The usability of the method is discussed in terms of computation time, and the achieved compromise between business relevance and classification performance during training.In this context, Interactive Clustering appears as a suitable methodology combining human and computer initiatives to efficiently develop a useable chatbot.
A Method for Generating Comparison Tables From the Semantic Web
Authors: Giacometti Arnaud , Markhoff Béatrice , Soulet Arnaud
Published: April 2022

This paper presents Versus, which is the first automatic method for generating comparison tables from knowledge bases of the Semantic Web. For this purpose, it introduces the contextual reference level to evaluate whether a feature is relevant to compare a set of entities. This measure relies on contexts that are sets of entities similar to the compared entities. Its principle is to favor the features whose values for the compared entities are reference (or frequent) in these contexts. The proposal efficiently evaluates the contextual reference level from a public SPARQL endpoint limited by a fair-use policy. Using a new benchmark based on Wikidata, the experiments show the interest of the contextual reference level for identifying the features deemed relevant by users with high precision and recall. In addition, the proposed optimizations significantly reduce the number of required queries for properties as well as for inverse relations. Interestingly, this experimental study also show that the inverse relations bring out a large number of numerical comparison features.
Density-Based Spatial Anomalous Window Discovery
Authors: Mohod Prerna , Janeja Vandana P.
Published: April 2022

The focus of this paper is to identify anomalous spatial windows using clustering-based methods. Spatial Anomalous windows are the contiguous groupings of spatial nodes which are unusual with respect to the rest of the data. Many scan statistics based approaches have been proposed for the identification of spatial anomalous windows. To identify similarly behaving groups of points, clustering techniques have been proposed. There are parallels between both types of approaches but these approaches have not been used interchangeably. Thus, the focus of our work is to bridge this gap and identify anomalous spatial windows using clustering based methods. Specifically, we use the circular scan statistic based approach and DBSCAN- Density based Spatial Clustering of Applications with Noise, to bridge the gap between clustering and scan statistics based approach. We present experimental results in US crime data Our results show that our approach is effective in identifying spatial anomalous windows and performs equal or better than existing techniques and does better than pure clustering.
Defining the Presence of Misrecognition in Multilingual Organizations

Published: April 2022

Research indicates the multilingual aspects of organizations can create power divisions and rules that drive workplace practices. From an international human resources development perspective, language management is strategic and planned through the headquarters of the organization. Yet the rational ideas of organizational members are what are truly valued in multilingual workplaces. These rational ideas create power struggles and biases that are formed against individuals who possess certain linguistic capabilities, regardless of the individual’s other traits or accomplishments. These biases have been labeled the phenomenon of misrecognition. This literature review explores the presence of misrecognition in multilingual organizations. A need to determine how the phenomenon of misrecognition exists in multilingual organizations was discovered.
Fast Path Reservation Scheduler
Authors: Kubde Vidya Sachin , Sawarkar Sudhir D.
Published: April 2022

In multihomed devices, Multipath Transmission Control Protocol is a transport layer protocol that allows TCP segments to be sent over several paths. We look at several Multipath TCP schedulers in this study and highlight some current outstanding concerns including head-of-line blocking, bandwidth aggregation, and out-of-order packets. The majority of these difficulties degrade MPTCP performance, which may be improved by constructing an MPTCP scheduler properly. Then, utilizing the bandwidth of all potential routes, we develop a novel MPTCP packet scheduler dubbed a Fast path reservation scheduler that not only helps to solve the aforesaid problems, but also delivers optimal throughput with a short execution time. The size of the receiver buffer or the size of the data being transmitted have no effect on the performance of FPRS, which transmits packets of data to the receiver in the order they were received. Both empirically and analytically, we show that the suggested scheduler outperforms the competition.

Published: April 2022

This research brings the relationships of human and technology interactions to the forefront in the delivery of an event and focuses upon the description of the various elements and their relationships within the Unified Theory of Acceptance and Use of Technology (UTAUT) model. An online survey method was used to investigate the applicability of the model amongst 276 respondents and examine relationships between various existing UTAUT variables with the addition of two variables viz Hedonic Motivations and Anxiety. The results of this study support the model and indicated that Performance Expectancy, Facilitating Conditions, and Social Influence are strong determinants of the use of virtual live events. These findings substantiate earlier research findings that show the relevance of the social context in technology adoption. This study is among the first to use the UTAUT model in the context of event technology and entertainment, especially in the developing country context.

Rapid growth in communication technology allows users location-independent access to IT infrastructure at pay-per-use via cloud computing. This has paved a new paradigm in information processing for the consumers. Due to Cloud's inherent characteristics, most service providers shift to the Cloud and its data centers. To retain Cloud's services' reliability, it's essential to carry out the minimum latency tasks and cost-effectively. Various techniques to improve performance and use of assets are focused on load control, task management, resource management, service quality, and workload management. Data load balancing helps data centers to avoid overload/underload of virtual machines, a difficulty in the world of cloud computing. This study reports a state-of-the-art analysis of current load balancing approaches', problems, and complexities to design more successful algorithms.
A Hybrid Approach to Discover Entity Synonyms
Authors: Kathuria Mamta , Nagpal Chander Kumar , Duhan Neelam
Published: April 2022

A major part of the current web information retrieval involves the fulfilment of people's daily needs based upon finding entities involving movies, events, persons, places, concepts, etc. The trend has been the outcome of the tremendous amount of precise and detailed information available on the web making it possible to retrieve the precisely targeted information involving specific instance of a particular domain called entity. The major problem in the entity-based search is the diversity of the name references made to the same instance of the same domain by the content creators and the searchers. These diversified references are known as entity synonyms. The problem is that they cannot be handled through lexical resources. This paper takes into account the previous works carried out in this direction and proposes an advanced mechanism that creates a richer set of entity synonyms than the previous approaches. The work also proposes an index to assess the quality of entity synonyms so generated which is further normalized and fuzzified for implementing automated search.
A Blockchain-Based Approach for Secure Data Migration From the Cloud to the Decentralized Storage Systems
Authors: Khan Hooria , Zahoor Ehtesham , Akhtar Sabina , Perrin Olivier
Published: April 2022

The use of the Cloud computing has been constantly on the rise. However, there are many challenges associated with the Cloud, such as high bandwidth requirements, data security, vendor lock-in and others. The recent rise of decentralized file systems (DFSs) can help mitigate some of these challenges. However, they have some limitations of their own and the current solutions do not provide any mechanism for implementing access control policies. This becomes a hurdle for migrating sensitive data from the Cloud as the associated authorization policies cannot be migrated to the DFSs. In this paper, the authors address the problem of migrating data, and associated authorization policies, from the Cloud to the DFS. They have applied the approach on the content and policies from an actual Cloud provider and it migrates data from AWS S3 to the IPFS and the resource-based authorization policies specified at AWS are added to a custom blockchain solution. The authors have provided implementation details to justify the practicality of the approach.

Published: April 2022

In order to enhance the customer experience, it is important not only to provide functions, but also to respond to changes in environments and requirements. It is a difficult task to evaluate and manage which function with different locations and contents is most valuable to the user's experience without using computationally time-consuming optimization calculations. To address this, this paper is focusing on self-adaptive software technology. The authors built a software adaptation mechanism that can be immediately calculated online using a performance characteristic map and threshold judgment with a learning function and sequential updates. The results confirmed the effectiveness of the mechanism in an application that supports personnel exchange events.

Authors: Gast Sarah , Barroso Julie , Blanchard Francesca A. , Campbell Amy A. , Carter Stacey J. , Clark Emma V. , Hilton Rachel , Branson Richard , Greenberg Steven , Kleinpell Ruth
Published: April 2022

Background

The COVID-19 pandemic has challenged health care professionals, especially those working in intensive care units (ICUs).

Objectives

To explore critical care nurses’ experiences with and perceptions of the COVID-19 pandemic during the early phases of the pandemic.

Methods

Data were from national surveys conducted during March and April 2020 to assess ICU providers’ perceptions of the initial phases of the pandemic. A total of 831 responses from nurses to open-ended questions were examined by using thematic analysis. The questions assessed potentially limited resources in the ICU, adequacy of staffing, and measures used to reduce the possibility of spreading COVID-19 to family members.

Results

Overarching themes concerned access to equipment and preventive measures taken to reduce exposure to the virus. These themes included “sheltering the patient when I don’t have enough” and “protecting those I love when I am a vector of transmission.” Subthemes for the first overarching theme included not having enough personal protective equipment, not enough staff and not enough properly trained staff, and not enough institutional support. Subthemes for the second overarching theme included “isolating myself from everyone I care about” and “isolating everything I touch from everyone I care about.”

Conclusions

This thematic analysis identified several concerns of ICU nurses related to caring for patients in the initial phases of the COVID-19 pandemic. Ensuring adequate supplies, staffing, and administrative and emotional support are provided to frontline health care providers during the ongoing pandemic remains essential.

Cleavage of the mammalian plasma protein C4 into C4b initiates opsonization, lysis, and clearance of microbes and damaged host cells by the classical and lectin pathways of the complement system. Dysregulated activation of C4 and other initial components of the classical pathway may cause or aggravate pathologies, such as systemic lupus erythematosus, Alzheimer disease, and schizophrenia. Modulating the activity of C4b by small-molecule or protein-based inhibitors may represent a promising therapeutic approach for preventing excessive inflammation and damage to host cells and tissue. Here, we present seven nanobodies, derived from llama (Lama glama) immunization, that bind to human C4b (Homo sapiens) with high affinities ranging from 3.2 nM to 14 pM. The activity of the nanobodies varies from no to complete inhibition of the classical pathway. The inhibiting nanobodies affect different steps in complement activation, in line with blocking sites for proconvertase formation, C3 substrate binding to the convertase, and regulator-mediated inactivation of C4b. For four nanobodies, we determined single-particle cryo-electron microscopy structures in complex with C4b at 3.4–4 Å resolution. The structures rationalize the observed functional effects of the nanobodies and define their mode of action during complement activation. Thus, we characterized seven anti-C4b nanobodies with diverse effects on the classical pathway of complement activation that may be explored for imaging, diagnostic, or therapeutic applications.

Classical activation of macrophage and monocyte differentiation induced by β-glucan is accompanied with metabolic change in glucose. However, the role of the metabolic rewiring in monocyte/macrophage activation remains elusive. In this study, we show that berberine induces aerobic glycolysis by blocking the tricarboxylic acid cycle and modulates cytokine responses in bone marrow–derived macrophages (BMDMs) from mice and human PBMC. 13-Methyberberine had activities on glucose metabolism and BMDM activation similar to those of berberine, whereas other tested derivatives lost both activities. Glucose transporter (GLUT)1 expression and total cellular hexokinase activity increased gradually in BMDMs in the presence of berberine. In the contrast, LPS upregulated GLUT1 and 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) levels in 6 h. Extracellular glucose levels and replacing glucose with galactose in culture medium affected the cytokine secretion of BMDMs. Berberine alleviated enteritis of Salmonella typhimurium infection and protected mice against endotoxic shock. In mice i.p. injected with LPS, the increase of serum TNF-α and the drop of blood glucose were attenuated by berberine treatment. These data together demonstrated that macrophage activation was closely related with glucose metabolism.

Authors: Ganiger Fakirappa Basavaraj , Bijjal Somashekhar , Safeekh A T , Sharma Manisha
Published: April 2022

Introduction:

Deliberate self-harm (DSH) is one of the leading causes of death and a major public health problem worldwide. According to the World Health Organization, DSH has increased by 60% over the past 50 years, of which 90% of victims had a psychiatric disorder.

Aims and Objectives:

The aim is to analyze the frequency, type, and lethality of DSH in bipolar affective disorder (BPAD) patients.

Materials and Methods:

This study included 150 patients diagnosed to have BPAD. Specially designed sociodemographic pro forma was used to record basic profile. DSH inventory was administered on BPAD patients who presented with DSH to analyze the type and lethality. Diagnosis of BPAD was made according to the International Classification of Diseases, tenth revision. Data were recorded, compiled, and analyzed using frequency and percentage with the IBM SPSS Statistics for Windows, Version 24.0.

Results:

The frequency of DSH was found to be 33%, out of which 38 (35%) patients had manic episode and 11 (30%) patients had depressive episode. The most common type of DSH was found to be cutting self with sharp or blunt objects and consumption of poison with frequency of 12 (24.5%) each. The second most common DSH was banging head, which was present in (11) 22.4% of patients.

Conclusion:

BPAD is associated with increased risk of DSH compared to the general population. The most common type of DSH was cutting self with sharp objects followed by consumption of poison. Patients who presented with DSH in depressive episode and severe mania had more lethal modes of DSH.

Authors: Babecoff Shai , Mermillod Florence , Marino Denis , Gayet-Ageron Angèle , Ansari Marc , Fernandez Eugenio , Gumy-Pause Fabienne
Published: April 2022

AIMS OF THE STUDY: Although the 5-year survival for pediatric cancer in Switzerland today is over 85%, two thirds of the survivors will develop chronic health conditions due to the disease or to the toxicity of treatments. In this context, a long-term personalized follow-up program (LTFU program), was set up at the University Hospitals of Geneva (HUG) since 2015. We aimed to describe this program, more particularly the specialized follow-ups set up, the cumulative burden of the chronic health conditions, and finally assess the satisfaction of patients and/or their parents with it.

METHODS: A monocentric retrospective study was performed where data on follow-ups and chronic health conditions were collected from medical charts of people who had childhood cancer and who participated in the LTFU program. Chronic health conditions were classified and graded in severity with the Common Terminology Criteria of Adverse Events (CTCAE) classification, version 5.0. This study was completed by a satisfaction survey among patients and/or their parents.

RESULTS: Out of 83 eligible patients, 51 (61.4%) accepted to participate, with an average age of 17.4 years (range, 10 to 35) at the time of study. Mean delay since end of treatment was 9.8 years (range: 4.5–31). The prevalence of any chronic health condition is 82.3%, 43.1% for having 1 or 2 chronic health conditions and 39.2% for having more than 3 chronic health conditions. The total number of Grade CTCAE 1–4 chronic health conditions was 118 for the 51 participants, with a mean of 2.3 (range, 0 to 7) disorders per patient. The most frequently affected systems were neurological (14.4%), musculoskeletal (13.6%), endocrine (9.3%) and renal (9.3%) systems. Sarcoma, central nervous system tumors and neuroblastoma were the diagnoses associated with the highest average number of chronic health conditions. Among the 118 questionnaires sent to patients and/or parents, we received 82 (69.5%) responses. The level of satisfaction was good to excellent for more than 90% of the participants, for all the items evaluated.

CONCLUSIONS: Childhood cancer survivors present a significant number of chronic health conditions, confirming the need for appropriate long-term, multidisciplinary and patient-specific medical follow-up based on the primary diagnosis and therapies received. Moreover, the LTFU program at the HUG was highly appreciated by patients and/or their parents and this motivates its permanent conduct.
The concept of General Consent in Switzerland and the implementation at the University Hospital Zurich, a cross-sectional study
Authors: Griessbach Alexandra , Bauer Annina , Jörger Lebet Francisca , Grossmann Regina
Published: April 2022

BACKGROUND: General Consent (GC) allows the further use of health-related data/samples for multiple, unspecified research projects and/or for the collection in databases and biobanks in Switzerland. The application of General Consent in the context of human research is regulated within the scope of the Human Research Act. At the University Hospital Zurich patients are informed about General Consent to which they can agree (GC = yes) or disagree (GC = no) to the use of their routinely collected data/samples in research. In this paper, we investigated the association of demographic and medical factors on a patient’s General Consent choice.
METHODS: In this cross-sectional study, we investigated the association of age, gender, number of visits and number of diagnoses on General Consent choice. The study population was stratified by General Consent status group (GC choice: Yes, No, Not issued) and examined by means of descriptive statistics, comparative statistics and a multinomial and logistic regression model. A p-value of 0.001 was determined as significant.
RESULTS: The female gender was found to associate with decreased odds in positive General Consent choice (<0.001) whereas age (<0.001) and number of diagnoses (<0.001) were associated with increased odds in positive General Consent choice (reference “GC = no” group). The number of visits (<0.001) as well as the number of diagnoses associated (<0.001) with increased General Consent collection (increase in positive as well as negative General Consent status).
CONCLUSION: General Consent is an innovative concept that simultaneously informs patients about human research in accordance with Swiss regulations and promotes research with routinely collected data and biological samples in an era with large information repositories. Our results show that medical and demographic factors may influence a patient’s choice. Therefore, approaching these populations and taking additional care to adequately inform and ensure ethical conformity and behaviour is essential. Flexible communication channels may help us reach this goal.

Bảo hiểm nhân thọ là một loại sản phẩm dịch vụ mang lại nhiều lợi ích cho người mua. Tuy vậy, ở Việt Nam nói chung, thành phố Hồ Chí Minh và quận Gò Vấp nói riêng tỷ lệ người dân mua bảo hiểm nhân thọ hãy còn thấp. Bởi vậy, xác định và đo lường mức độ ảnh hưởng của các yếu tố đến ý định mua bảo hiểm nhân thọ của người dân với nghiên cứu điển hình tại quận Gò Vấp là cần thiết. Kết quả xử lý dữ liệu từ cuộc khảo sát trực tuyến 250 người dân có ý định mua bảo hiểm nhân thọ bằng phần mềm SPSS 20 đã đo lường được mức độ ảnh hưởng của 05 yếu tố có trong mô hình nghiên cứu theo thứ tự là chuẩn chủ quan, thái độ đối với việc mua bảo hiểm nhân thọ, dịch vụ của công ty bảo hiểm nhân thọ, động cơ tiết kiệm và cuối cùng là nhận thức kiểm soát hành vi. Từ kết quả nghiên cứu, năm khuyến nghị nhằm tăng cường ý định mua bảo hiểm nhân thọ của người dân đã được đưa ra. Hy vọng rằng, lượng khách hàng mua bảo hiểm nhân thọ sẽ tăng lên khi các công ty bảo hiểm thực hiện những khuyến nghị này.

Ý định thăm lại điểm đến du lịch của du khách có ảnh hưởng trực tiếp đến việc tăng doanh thu của các doanh nghiệp khai thác du lịch. Du lịch sinh thái cộng đồng (STCĐ) là một loại hình du lịch hấp dẫn luôn có sức hút riêng đối với du  khách. Do đó, mục tiêu của nghiên cứu này là phát triển một thang đo lường hợp lệ và đáng tin cậy sẽ hỗ trợ việc tìm hiểu các khái niệm và cải thiện việc quản lý hiệu quả về ý định hành vi của khách du lịch STCĐ tại các homestay vùng ĐBSCL. Dựa vào quy trình được đề xuất bởi [1] và [2], chúng tôi đã phát triển thang đo các yếu tố tác động đến ý định thăm lại điểm đến của khách du lịch STCĐ tại các homestay gồm 24 biến quan sát với 05 yếu tố, qua đó chúng tôi tin rằng có thể áp dụng cho hầu hết các khu vực điểm đến du lịch STCĐ. Bộ thang đo này gồm 05 yếu tố: hình ảnh điểm đến, chất lượng dịch vụ cảm nhận, sự hài lòng, niềm tin, và ý định thăm lại điểm đến. Ý nghĩa về mặt lý thuyết và thực tiễn của kết quả nghiên cứu cũng được thảo luận chi tiết.
