Abstract. Delay discounting (DD) is the process of devaluing results that happen in the future. With this review, we intend to identify specificities in the processes of DD in impulsive behavior. Studies were retrieved from multiple literature databases, through rigorous criteria (we included systematic reviews and empirical studies with adult human subjects), following the procedures of the Cochrane Collaboration initiative. Of the 174 documents obtained, 19 were considered eligible for inclusion and were retained for in-depth analysis. In addition, 13 studies from the manual search were included. Thus, a total of 32 studies were selected for review. The objectives/hypotheses, results, and the main conclusion(s) were extracted from each study. Results show that people with pronounced traits of impulsivity discount rewards more markedly, that is, they prefer immediate rewards, though of less value, or postponed losses, even though they worsen in the future. Taken together, the existing data suggest the importance of inserting DD as a tool for initial assessment in conjunction with measures of addiction and stress level, as well as the consideration of new therapies.

Maladaptive Beliefs

Beliefs that are too rigid and misadjusted may legitimize interpersonal relationships marked by verbal, physical, or sexual violence. A systematic literature review was performed to identify the existence of maladaptive beliefs (MBs) in interpersonal relationships of young adults and their association with problematic behaviors. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, studies were obtained through a search in multiple databases: EBSCOhost, PubMed, and Web of Science. Of the 1,280 articles retrieved, 42 were retained for further analysis and 15 were considered eligible for inclusion. In addition, seven studies were added through manual search, leading to a final sample of 15 articles, published between 1964 and 2021. Only empirical studies with quantitative methodologies were included. Objectives, sample (age in years), sample type, country of origin of studies, instruments, control group, and results and main conclusions were extracted from each study. Results suggest the existence of MBs that may legitimize antisocial behavior and violence, whether physical, sexual, gender, domestic, or in intimate relationships. Some intervention programs were also identified, with different approaches with a reasonable degree of efficacy in changing these beliefs or in reducing the rates of recidivism by the aggressors.

Grasp Quality

The involvement of Robots and automated machines in different industries has increased drastically in recent years. Part of this revolution is accomplishing tasks previously performed by humans with advanced robots, which would replace the entire human workforce in the future. In some industries the workers are required to complete different operations in hazardous or difficult environments. Operations like these could be replaced with the use of tele-operated systems that have the capability of grasping objects in their surroundings, thus abandoning the need for the physical presence of the human operator at the area while still allowing control. In this research our goal is to create an assisting system that would improve the grasping of a human operator using a tele-operated robotic gripper and arm, while advising the operator but not forcing a solution. For a given set of objects we computed the optimal grasp to be achieved by the gripper, based on two grasp quality measures of our choosing (namely power grasp and precision grasp). We then tested the performance of different human subjects who tried to grasp the different objects with the tele-operated system, while comparing their success to unassisted and assisted grasping. Our goal is to create an assisting algorithm that would compute optimal grasps and might be integrated into a complete, state-of-the-art tele-operated system.

Abstract Background Developing a safe and effective vaccine will be the principal way of controlling the COVID-19 pandemic. However, current COVID-19 vaccination trials are not adequately representing a diverse participant population in terms of age, ethnicity and comorbidities. Achieving the representative recruitment targets that are adequately powered to the study remains one of the greatest challenges in clinical trial management. To ensure accuracy and generalisability of the safety and efficacy conclusions generated by clinical trials, it is crucial to recruit patient cohorts as representative as possible of the future target population. Missing these targets can lead to reduced validity of the study results and can often slow down drug development leading to costly delays. Objective This study explores the key factors related to perceptions and participation in vaccination trials. Methods This study involved an anonymous cross-sectional online survey circulated across the UK. Statistical analysis was done in six phases. Multi-nominal logistic models examined demographic and geographic factors that may impact vaccine uptake. Results The survey had 4884 participants of which 9.44% were Black Asian Minority Ethnic (BAME). Overall, 2020 (41.4%) respondents were interested in participating in vaccine trials; 27.6% of the respondents were not interested and 31.1% were unsure. The most interested groups were male (OR = 1.29), graduates (OR = 1.28), the 40–49 and 50–59 age groups (OR = 1.88 and OR = 1.46 respectively) and those with no health issues (OR = 1.06). The least interested groups were BAME (OR = 0.43), those from villages and small towns (OR = 0.66 and 0.54 respectively) and those aged 70 and above (OR = 1.11). Conclusions In order to have a vaccination that is generalisable to the entire population, greater work needs to be done in engaging a diverse cohort of participants. Public health campaigns need to be targeted in improving trial recruitment rates for the elderly, BAME community and the less educated rural population.

Multiple Case

PurposeThrough a multiple case study design, this article elaborates the chances of initiating and/or implementing responsible management education (RME) in Egyptian public business schools after the identification of coronavirus disease 2019 (COVID-19). In other words, this paper identifies the effect of COVID-19 on internalizing RME in the previously mentioned context.Design/methodology/approachThrough addressing four business schools in Egypt, this article explores the future of public business schools that did not previously implement responsible management education (RME) principles, after the identification of COVID-19. In other words, this paper identifies the main threats facing public business schools in Egypt post the spread of COVID-19.FindingsAlthough the previous study done by Mousa et al. (2019a) showed that academics in public business schools in Egypt were not ready to implement responsible management education, and furthermore, that they thought that addressing socio-cultural aspects is the mission of professors in sociology and humanities, the results of this study show that the spread of COVID-19 has positively changed the situation. The interviewed academics assert that socio-cultural challenges shape the minds of business students, academics and trainers, and these accordingly, have to be tackled. Furthermore, the author explores some socio-political, academic and labour market threats facing business schools in Egypt today. Managing those threats may ensure the continuity of the addressed business schools and their counterparts.Originality/valueThis paper contributes by filling a gap in the literature on responsible management education and leadership in the higher education sector, in which empirical studies on the future of business schools, particularly those that did not implement responsible management education earlier, after the identification and spread of COVID-19 have been limited until now.

Abstract In 2001, the Ministry of Education of the People’s Republic of China issued guidelines to promote the quality of higher education and to advocate the expansion of the use of English (Ministry of Education (MoE). 2001. Guanyu jiaqiang gaodeng xuexiao benke jiaoxue gongzuo tigao jiaoxue zhiliang de ruogan yijian [Guidelines for Improving the Quality of Undergraduate Teaching at Higher Education Institutions]. Available at: http://old.moe.gov.cn/publicfifiles/business/htmlfifiles/moe/moe_309/200412/4682.html). This paper reviews empirical studies in English and Chinese on EMI in Chinese higher education published from 2001 to 2019, during the last two decades since these guidelines were released. The review contributes to the field of EMI by documenting, analysing and synthesising empirical evidence and by situating EMI studies in China in the global trends of EMI research. The review aims to give an overview of studies targeted at both global and local audiences, therefore, publications in both English and Chinese were included. To select the Chinese articles the core journals indexed by CNKI were searched, and for the English articles, we used ERIC, IBSS, SCOPUS and WOS databases. After excluding theoretically oriented studies, literature reviews and commentaries, 42 articles remained. The in-depth analysis revealed that the main topics of these studies included the student perception, implementation and educational practices, and the role of language. We conclude that in general there are insufficient empirical studies, especially about EMI teachers’ perspectives to inform policies and practices at the micro, meso and macro level. Based on the findings, directions for further research are identified and recommendations for methodological approaches for future studies are also made.

Monetary Choice Questionnaire

Humans frequently create mental models of the future, allowing outcomes to be inferred in advance of their occurrence. Recent evidence suggests that imagining positive future events reduces delay discounting (the devaluation of reward with time until its receipt), while imagining negative future events may increase it. Here, using a sample of 297 participants, we experimentally assess the effects of cued episodic simulation of positive and negative future scenarios on decision-making in the context of both delay discounting (monetary choice questionnaire) and risk-taking (balloon-analogue risk task). Participants discounted the future less when cued to imagine positive and negative future scenarios than they did when cued to engage in control neutral imagery. There were no effects of experimental condition on risk-taking. Thus, although these results replicate previous findings suggesting episodic future simulation can reduce delay discounting, they indicate that this effect is not dependent on the valence of the thoughts, and does not generalise to all other forms of “impulsive” decision-making. We discuss various interpretations of these results, and suggest avenues for further research on the role of prospection in decision-making.

<p>This paper explores types of accounting choice related to reporting goodwill impairment losses, if any, exercised by Malaysian listed firms after an implementation of IFRS 3. The study is carried out through an in-depth analysis of annual reports for fifteen firms over a number of years. The fifteen firms selected are those that have goodwill arising from business combinations in December 2006/7, reported goodwill impairment losses in the current year or the future year(s), and the goodwill represents 50% or more of the acquisition price. Results show that of the fifteen firms examined, eight firms appeared to exercise the accounting choice in the form of opportunistic timing in reporting the impairment losses. The study contributes to the accounting choice literature by providing evidence on the timing of goodwill impairment losses for goodwill that arose from an apparent overpayment made at the time of an acquisition of a subsidiary.</p>

Based Medicine

In an era of evidence-based medicine, policy-makers and researchers are preoccupied by the task of ensuring that advances in research are implemented in routine clinical practice. This preoccupation has spawned a small but growing research industry of its own, with the development of resources such as the Cochrane Collaboration database and journals such as Evidence-Based Mental Health. In this paper, I adopt a philosophically quite unfashionable methodology – introspection – to address the question: how has research affected my practice?

Based on the presented study results, it can be concluded that the distribution of tree numbers per diameter degrees (diameter structure) in the four measurements of the compartments 51 and 75, did not change. It was also concluded that one functional dependence could be applied for both compartments N=e5,9?e?0,39*d The result of the above is that also in the following measurements, the diameter structure will remain unchanged, in cases of the same or similar selection cuttings both by the scope and by the distribution of felled trees per diameter classes The primary objective of this type of study is to predict, based on a mathematical model of diameter structure development, effect of the scope of selection cuttings and the number of recruitments on the diameter structure, and the simulation of growth, the distribution of trees per diameter classes in the following measurement or measurements, i.e. to foresee the future development of selection stands.
