基于作答时间数据的改变点分析在检测加速作答中的探索——已知和未知项目参数

相对于传统的离散作答数据, 作答时间作为连续数据, 可以提供更多信息。改变点分析(change point analysis)技术在心理和教育领域是一个比较新的技术。本文一方面对改变点分析在心理测量领域的应用进行了一个综合的总结和分析; 另一方面, 将基于作答数据的两种改变点分析统计量推广到作答时间数据, 将改变点分析技术应用到测验异常作答模式：加速作答speededness的检测上。采用两种检验方法：似然比检验和Wald检验, 分别在已知和未知项目参数的条件下, 实现异常作答模式的检测。结果表明, 所采用的方法对于加速作答行为的检测具有很高的检验力, 同时能够很好的控制I类错误率。实证数据分析进一步表明本文中所使用的方法具有应用价值。     

What happens when drivers of automated vehicles take over control in critical lane change situations?

According to legislation, take-overs initiated by the driver must always be possible during automated driving. For example, when drivers mistrust the automation to handle a critical and hazardous lane change, they might intervene and take over control while the automation is performing the maneuver. In these situations, drivers may have little time to avoid an accident and can be exposed to high lateral forces. Due to lacking research, it is yet unknown if they recognize the criticality of the situation and how they behave and perform to manage it. In a driving simulator study, participants (N = 60) accomplished eight double lane changes to evade obstacles in their lane. Time-to-collision and traction usage were varied to establish different degrees of objective criticality. To manipulate these parameters as required, participants were triggered to take over control by an acoustic cue. This setting shows what might happen if drivers disable the automation and complete the maneuver themselves. The results of the experiment demonstrate that drivers rated objectively more critical driving situations as more critical and responded to the hazard very fast over all experimental conditions. However, their behavior was more extreme with respect to decelerating and steering than necessary. This impaired driving performance and increased the risk of lane departures and collisions. The results of the experiment can be used to develop an assistance system that supports driver-initiated take-overs.     

What Would It Take to Change Your Mind?

Most of us have settled views about various intellectual debates, and much of the activity of philosophers is devoted to giving arguments that are designed to convince one's opponents to change their minds about a certain issue. But, what might this process require? More pointedly, can you clearly imagine what it would take to make you change your mind about a position you currently hold? This article argues that the surprising answer to this question is no—you cannot imagine what would convince you to change your mind, since in doing so you would actually have to find those reasons compelling. The article then briefly looks at some implications of this conclusion.     

A qualitative study of citizens' experience of participating in health counseling

Individual health counseling is a form of intervention designed to minimize the effects of chronic health disease and to offer a path towards good health practices. The aim of the present study was to explore the experiences of those persons who participated in health counseling in order to assess the psychosocial significance of the counseling upon their health behavior. In addition the study was concerned with the factors which underlay peoples' decision to sign up for health counseling. The research involved 11 semi‐structured interviews with individuals who had participated in a municipality based health counseling program. Data was analyzed using Malterud's systemic text condensation and a theoretical framework around Bandura's social cognitive theory. Analysis revealed that an approach tailored to each individual with minor short‐term goals accompanied by feeling supported by the counselor produced the greatest impact on behavior. Receiving feedback from the counselor and feeling positive about the relationship were seen as essential. These aspects were also crucial in the decision to undertake health counseling. The study indicates that whether individual's sign up on their own initiative or conversely are invited to join the program has no influence upon their motivation to change their behavior. Overall the respondents demonstrated improvement in their behavior and attitudes towards their health. However, the study also indicates that this form of intervention is less or even ineffective without the support of the individual's immediate family.

The four tasks of development ethics at times of a changing climate

This paper argues that the challenges posed by climate change and the need to quickly move toward a sustainable low-carbon future require the contributions of development ethics. I propose four tasks for development ethics. The first relates to unpacking the urgency posed by climate change by showing how, from an ethical perspective, the impacts of climate change are extremely dangerous risks, especially for those most vulnerable, and thus require immediate attention. The second relates to a better understanding of the components of well-being. The third relates to concerns regarding the global commons and to the need to reframe key components of socio-ecological balance as public goods. The fourth and last task of development ethics refers to the multiple trade-offs and dilemmas in the processes leading to a low-carbon and equitable future arguing for strengthening public deliberation and democracy.     

Global ethics: increasing our positive impact

Global ethics is no ordinary subject. It includes some of the most urgent and momentous issues the world faces, such as extreme poverty and climate change. Given this, any adequate review of that subject should, I suggest, ask some questions about the relation between what those working in that subject do and the real-world phenomena that are the object of their study. The main question I focus on in this essay is this: should academics and others working in the field of global ethics take new measures aimed at having more real-world positive impact on the phenomena they study? Should they take new measures, that is, aimed at bringing about more improvements in those phenomena, improvements such as reductions in extreme poverty and in emissions of greenhouse gases? I defend a positive answer to this question against some objections, and also discuss some of the kinds of measure we might take in an attempt to have more positive impact.     

The naked truth: mindfulness and the purification of religion

To arrive at an understanding of what drives the much debated spiritual turn in Western Europe, we study the spiritual trajectories and identifications of mindfulness practitioners in the formerly predominantly Roman Catholic context of Flanders in Belgium. Fifteen semi-structured interviews addressed their religious and spiritual biographical trajectories as well as the symbolic boundaries they draw with adjacent religious and spiritual groups. We find marked evidence of a process of ‘religious purification’, which unfolds as a critique of the formal and external aspects of both religion (organisations, dogmas, ritual) and spirituality (woolly and frivolous New Age word games). To validate and justify, alternatively, the ‘pure’ and ‘grounded’ spirituality that results, those concerned consistently invoke the authority of science.     

Relationships between core ideological motives,social and economic conservatism,and religiosity: Evidence from a Turkish sample

The “conservatism as motivated social cognition” approach posits two core ideological motives underlying political conservatism across cultures. However, there is a scarcity of tests from non‐Western cultures, and much research has failed to distinguish between social and economic conservatism. Using a relatively large undergraduate sample from a non‐Western, predominantly Muslim country (Turkey), we tested the associations among resistance to change and opposition to equality motives, social and economic conservatism, right‐wing political orientation, and religiosity. In line with the “conservatism as motivated social cognition” account, we found that (a) social conservatism is more strongly related to resistance to change (rather than opposition to equality), (b) economic conservatism is more strongly related to opposition to equality (rather than resistance to change), (c) social conservatism is the strongest predictor of right‐wing political orientation among other conservatism measures, and (d) political orientation and religiosity had divergent effects: While right‐wing political orientation was related to economic conservatism, religiosity was inversely related to the latter, providing support for previous work indicating a resemblance between leftists and Islamists in Turkey. The results generally support the motivated social cognition approach to conservatism while also highlighting the importance of distinguishing between social and economic conservatism.     

Un cadre psychosocial d’intervention pour accompagner le développement et le déploiement d’une technologie nouvelle

This article presents a psychosocial intervention framework to support the development and deployment of a new technology. This methodology articulates the three phases necessary for the study of the representation of the use and its evolutions (i.e., the usual trajectory): acceptability, acceptance and appropriation. After an argumentative presentation of the methodological choices made, the article continues with the presentation of an example of accompaniment carried out within the framework of the IDViandes project aimed at the development of a traceability device for meat containers Of slaughter within the company SVA Jean-Rozé, subsidiary of the Intermarché group. This example argues in favor of the idea that the use of such a method makes it possible to optimize the successful accompaniment of the development of a technology and thus ensure its future diffusion.
