A Look Into the Power of fNIRS Signals by Using the Welch Power Spectral Estimate for Deception Detection.Jiang Zhang,Jingyue Zhang,Houhua Ren,Qihong Liu,Zhengcong Du,Lan Wu,Liyang Sai,Zhen Yuan,Site Mo &Xiaohong Lin -2021 -Frontiers in Human Neuroscience 14.detailsNeuroimaging technologies have improved our understanding of deception and also exhibit their potential in revealing the origins of its neural mechanism. In this study, a quantitative power analysis method that uses the Welch power spectrum estimation of functional near-infrared spectroscopy signals was proposed to examine the brain activation difference between the spontaneous deceptive behavior and controlled behavior. The power value produced by the model was applied to quantify the activity energy of brain regions, which can serve as a neuromarker for (...) deception detection. Interestingly, the power analysis results generated from the Welch spectrum estimation method demonstrated that the spontaneous deceptive behavior elicited significantly higher power than that from the controlled behavior in the prefrontal cortex. Meanwhile, the power findings also showed significant difference between the spontaneous deceptive behavior and controlled behavior, indicating that the reward system was only involved in the deception. The proposed power analysis method for processing fNIRS data provides us an additional insight to understand the cognitive mechanism of deception. (shrink)
A Decision-Making Model Using Machine Learning for Improving Dispatching Efficiency in Chengdu Shuangliu Airport.Yingmiao Qian,Shuhang Chen,Jianchang Li,Qinxin Ren,Jinfu Zhu,Ruijia Yuan &Hao Su -2020 -Complexity 2020:1-16.detailsDue to the increasing number of people traveling by air, the passenger flow at the airport is increasing, and the problem of passenger drop-off and pickup has a huge impact on urban traffic. The difficulty of taking a taxi at the airport is still a hot issue in the society. Aiming at the problem of optimizing the allocation of taxi resource, this paper is based on the cost-benefit analysis method to determine the factors that affect the taxi driver’s decision-making. The (...) mathematical methods such as function equation, BP neural network algorithm, and queuing theory were used to establish a complete decision-making model for taxi drivers and an optimization model of dispatching efficiency at the airport. A conclusion has been drawn that the allocation of airport taxi resource should be arranged closely related to drivers’ revenue and the layout of airport line. (shrink)
Scientific dishonesty—a nationwide survey of doctoral students in Norway.Bjørn Hofmann,Anne Ingeborg Myhr &Søren Holm -2013 -BMC Medical Ethics 14 (1):3-.detailsBackground: The knowledge of scientific dishonesty is scarce and heterogeneous. Therefore this study investigates the experiences with and the attitudes towards various forms of scientific dishonesty among PhD-students at the medical faculties of all Norwegian universities.MethodAnonymous questionnaire distributed to all post graduate students attending introductory PhD-courses at all medical faculties in Norway in 2010/2011. Descriptive statistics. Results: 189 of 262 questionnaires were returned (72.1%). 65% of the respondents had not, during the last year, heard or read about researchers who committed (...) scientific dishonesty. One respondent had experienced pressure to fabricate and to falsify data, and one had experienced pressure to plagiarize data. On average 60% of the respondents were uncertain whether their department had a written policy concerning scientific conduct. About 11% of the respondents had experienced unethical pressure concerning the order of authors during the last 12 months. 10% did not find it inappropriate to report experimental data without having conducted the experiment and 38% did not find it inappropriate to try a variety of different methods of analysis to find a statistically significant result. 13% agreed that it is acceptable to selectively omit contradictory results to expedite publication and 10% found it acceptable to falsify or fabricate data to expedite publication, if they were confident of their findings. 79% agreed that they would be willing to report misconduct to a responsible official. Conclusion: Although there is less scientific dishonesty reported in Norway than in other countries, dishonesty is not unknown to doctoral students. Some forms of scientific misconduct are considered to be acceptable by a significant minority. There was little awareness of relevant policies for scientific conduct, but a high level of willingness to report misconduct. (shrink)
Transsexuals in Sport–Fairness and Freedom, Regulation and Law.John Coggon,Natasha Hammond &S. ⊘ren Holm -2008 -Sport, Ethics and Philosophy 2 (1):4-17.detailsThe question of if, and under what conditions transsexuals should be allowed to participate in sports in their acquired sex is becoming increasingly relevant partly because the number of transsexuals is increasing partly because many countries now provide mechanisms for achieving legal recognition as belonging to the new acquired sex. This paper develops (1) an analysis of the justification for maintaining sex segregation in some sports and (2) an account of the rights of transsexuals to be recognised in their new (...) sex. On the basis of these two analyses it critically evaluates two set of rules for the participation of transsexuals in elite sports: the UK guidelines issued in pursuance of the Gender Recognition Act 2004 and the International Olympic Committee's guidelines. It is argued that these guidelines are conflicting and that a modified set of criteria is more justifiable. (shrink)
High-Density Lipoproteins-Associated Proteins and Subspecies Related to Arterial Stiffness in Young Adults with Type 2 Diabetes Mellitus.Xiaoting Zhu,Amy S. Shah,Debi K. Swertfeger,Hailong Li,Sheng Ren,John T. Melchior,Scott M. Gordon,W. Sean Davidson &L. Jason Lu -2018 -Complexity 2018:1-14.detailsLower plasma levels of high-density lipoproteins in adolescents with type 2 diabetes have been associated with a higher pulse wave velocity, a marker of arterial stiffness. Evidence suggests that HDL proteins or particle subspecies are altered in T2D and these may drive these relationships. In this work, we set out to reveal any specific proteins and subspecies that are related to arterial stiffness in youth with T2D from proteomics data. Plasma and PWV measurements were previously acquired from lean and T2D (...) adolescents. Each plasma sample was separated into 18 fractions and evaluated by mass spectrometry. Then, we applied a validated network-based computational approach to reveal HDL subspecies associated with PWV. Among 68 detected phospholipid-associated proteins, we found that seven were negatively correlated with PWV, indicating that they may be atheroprotective. Conversely, nine proteins show positive correlation with PWV, suggesting that they may be related to arterial stiffness. Intriguingly, our results demonstrate that apoA-I and histidine-rich glycoprotein may reverse their protective roles and become antagonistic in the setting of T2D. Furthermore, we revealed two arterial stiffness-associated HDL subspecies, each of which contains multiple PWV-related proteins. Correlation and disease association analyses suggest that these HDL subspecies might link T2D to its cardiovascular-related complications. (shrink)

The Ethics of COVID-19 Vaccine Allocation: Don't Forget the Trade-Offs!Julian W. März,Anett Molnar,Søren Holm &Michael Schlander -2022 -Public Health Ethics 15 (1):41-50.detailsThe issue of COVID-19 vaccine allocation is still highly controversial on the international as well as on the national level, and policy-makers worldwide struggle in striking a fair balance between different ethical principles of vaccine allocation, in particular maximum benefit, reciprocity, social justice and equal respect. Any political decision that implements these principles comes at a cost in terms of loss of lives and of loss of life years that could potentially have been prevented by a different vaccination strategy. This (...) article illustrates these trade-offs using quantitative analysis and shows how this approach can contribute to providing a rational and transparent grounding of political decisions on COVID-19 vaccine allocation.

Analogical reasoning in handling emerging technologies: The case of umbilical cord blood biobanking.Bjørn Hofmann,Jan Helge Solbakk &Søren Holm -2006 -American Journal of Bioethics 6 (6):49 – 57.detailsHow are we individually and as a society to handle new and emerging technologies? This challenging question underlies much of the bioethical debates of modern times. To address this question we need suitable conceptions of the new technology and ways of identifying its proper management and regulation. To establish conceptions and to find ways to handle emerging technologies we tend to use analogies extensively. The aim of this article is to investigate the role that analogies play or may play in (...) the processes of understanding and managing new technology. More precisely we aim to unveil the role of analogies as analytical devices in exploring the "being" of the new technology as well the normative function of analogies in conceptualizing the characteristics and applications of new technology. Umbilical cord blood biobanking will be used as a case to investigate these roles and functions. (shrink)
A University Wide Model for the Ethical Review of Human Subjects Research.Bryn Williams-Jones &Søren Holm -2005 -Research Ethics 1 (2):39-44.detailsIn the United Kingdom (and elsewhere), there are moves to extend formal ethical review of research involving human subjects beyond the traditional oversight by NHS local or multi-centre research ethics committees of medical or clinical research, to also encompass all ‘non-clinical’ research involving human subjects. This paper describes and analyses the development and implementation of a model for ethical review within the university sector. At Cardiff University, a devolved or two-tiered system of ethics review has been created in which a (...) top-level university research ethics committee provides policy advice to and oversight of school-based research ethics committees that engage in formal ethics review of research conducted in their respective schools. We describe the system and reflect on the challenges and benefits of implementing such a coordinated and comprehensive university-wide system of ethics review. (shrink)
Schopenhauer - Kierkegaard: Von der Metaphysik des Willens Zur Philosophie der Existenz.Niels Jørgen Cappelørn,Lore Hühn,Søren R. Fauth &Philipp Schwab (eds.) -2011 - De Gruyter.detailsThis book undertakes an extensive study of the constellation of two eminent thinkers of post-idealism for the first time. The contributions in this volume analyze the relationship between Schopenhauer and Kierkegaard systematically and historically from a number of thematic perspectives: metaphysics and ethics, freedom and original sin, existential philosophy and the theory of suffering, art and aesthetics, religion and science. The book also goes into Kierkegaard s explicit disagreement with Schopenhauer and last but not least discusses the conflicting poles of (...) idealism and modernity. The volume is rounded off by a first complete and annotated German translation of the notes on Schopenhauer, which Kierkegaard wrote in his late journals.". (shrink)

The Impact of Self-Relevance on Preschool Children’s Sharing.Wenjie Zhang,Songmei Xiang,Hongmei Dai,Mengmeng Ren,Yuqi Shen,Wei Fan &Yiping Zhong -2019 -Frontiers in Psychology 10.detailsThis study was designed to investigate the impact of self-relevance between preschool children and recipients on children’s sharing behavior in dictator games using a forced-choice resource distribution paradigm. Experiment 1: A total of 75 children aged 3-6 years were evaluated in a first-party situation in which they were distributed as recipients and dictators and shared resources with distracting recipients with different extents of self-relevance under three different payoff structures, including non-costly, costly and envy structures. Children could choose between a sharing (...) option and a non-sharing option. The results showed that, in a first-party situation, children aged 3-6 years old typically share more resources with highly self-relevant recipients (friends) than with moderately self-relevant recipients (acquaintances) and lowly self-relevant recipients (strangers) and that they share more resources with moderately self-relevant recipients (acquaintances) than lowly self-relevant recipients (strangers). Experiment 2: A total of 62 children aged 3-6 years old were evaluated in a third-party situation in which they were distributed not as recipients but only dictators, making decisions between the options of sharing more or sharing less with distracting recipients who had different extents of self-relevance under three different payoff structures, such as non-bias, high self-bias and low self-bias. The results showed that, in a third-party situation, children typically share in a similar manner to that of Experiment 1, meaning that children display selective generosity and that the self-relevance between the children and recipients played a key role. Across age groups, this study of preschool children (total N = 137) demonstrates a degree of effect of self-relevance on preschool children’s sharing in first-party and third-party situations, with highly self-relevant recipients receiving a more preferential share in the dictator game than those with low self-relevance, although this effect was stronger in the older preschool children.

Information Diffusion Model of Social Bots: An Analysis of the Spread of Coverage of China Issues by The New York Times on Twitter.Na Han,Hebo Huang,Jianjun Wang,Bin Shi &Li Ren -2022 -Complexity 2022:1-9.detailsSocial-bots-mediated information manipulation is influencing the public opinion environment, and their role and behavior patterns in news proliferation are worth exploring. Based on the analysis of bots' posting frequency, influence, and retweeting relationship, we take the diffusion of The New York Times' coverage of Xinjiang issue on the overseas social platform Twitter as an example and employ the two-step flow model. It is found that in the role of second-step diffusion, unlike posting news indiscriminately in first-step diffusion, social bots are (...) more inclined to postcontroversial information in second-step diffusion; in terms of diffusion patterns, although social bots are more engaged in first-step diffusion than in second-step diffusion and can trigger human users to retweet, they are still inferior to humans in terms of influence.

Pitsiladis (eds.) -2012 - Lexington Books.detailsThe Anthropology of Sport and Human Movement represents a collection of work that reveals and explores the often times dramatic relationship of our biology and culture that is inextricably woven into a tapestry of movement patterns. It explores the underpinning of human movement, reflected in play, sport, games and human culture from an evolutionary perspective and contemporary expression of sport and human movement.
Work-Family Conflict, Happiness and Organizational Citizenship Behavior Among Professional Women: A Moderated Mediation Model.Ying Pan,Nadilai Aisihaer,Qinyi Li,Yue Jiao &Shengpei Ren -2022 -Frontiers in Psychology 13.detailsThis study investigates the association between work-family conflict and organizational citizenship behavior and examines the mediated role of subjective happiness between and the moderated part of family support. A moderated mediation model is established based on the Conservation of Resources theory. We collected data from 386 employees of nine companies in China. This study shows that the work-family conflict of female professional employees is negatively correlated with organizational citizenship behavior, and that the relationship is mediated by subjective well-being. Furthermore, female (...) professional employees’ family support moderates the effects of work-family conflict on subjective happiness and organizational citizenship behavior, with the relationship weaker when family support is higher. This study enriches the literature on work-family conflict by using family support as a mediating mechanism for work-family conflict. It enhanced our understanding of the influencing mechanisms of organizational citizenship behavior by constructing a more detailed model. (shrink)
Development and Validation of Chinese Parental Involvement and Support Scale for Preschool Children.Yaping Yue,Xiangru Zhu,Yisi Zhang &Wanyu Ren -2022 -Frontiers in Psychology 13.detailsThe present study developed the Chinese Parental Involvement and Support Scale for Preschool Children to measure parental involvement and support for preschool children. In Study 1, we conducted a literature review, open-ended interviews, a theoretical analysis, and expert interviews to create an item bank. In Study 2, 447 parents completed the item bank. Following item and Exploratory Factor Analysis, 30 items were retained. In Study 3, five new items were added to the 30-item version of the CPISSPC. A separate sample (...) of 471 parents completed the 35-item version of the CPISSPC. After Confirmatory Factor Analysis, a final 18-item version of the CPISSPC was created with four factors: psychological support, educational support, play support, and life support. Construct validity and internal reliability were satisfactory. Study 4 evaluated concurrent validity. CPISSPC scores significantly and positively correlated with perceived social support, marital gratification, and children’s self-efficacy. CPISSPC scores significantly and negatively correlated with parents’ levels of burnout and loneliness. The CPISSPC exhibits good psychometric properties and can be used as a tool to measure parental involvement and support for preschool children. (shrink)
