Cyclist strategies and behaviour at intersections. Conscious and un-conscious strategies regarding positioning

Severe and even fatal accidents between cyclists and motor vehicles commonly occur at intersections. Many of these accidents occur with right-turning vehicles, with drivers not observing an adjacent cyclist. Few structured investigations exist regarding the interaction between cyclist and motor vehicle, and factors in need of study are how infrastructure and vehicle properties affect human decision-making and cycling behaviour. Therefore, a bicycle simulator study was performed, where vehicle type, presence of lane markings and lane width were systematically varied in a scenario with a cyclist approaching a vehicle from behind, at a signalized city intersection. 33 participants cycled through 8 intersection variants each. Data on cycling trajectories, stopping points and speed was coupled with survey data from the participants, and semantically categorized verbal responses to questions regarding strategy for choice of stopping point. Results show that all three factors (vehicle type, lane markings and available vehicle-adjacent space) significantly affects cyclists’ behaviour and conscious strategies. Participants were more cautious in the presence of a truck than a car, reflected in choice of position when cycling and stopping, and in explicit verbalisations regarding perilous aspects of the situation and their conscious and strategic choice of positioning. Available lateral space also affected stop positions and feeling of safety (expressed verbally). Presence of bicycle lane markings made the cyclists inclined to continue into the space to the right of the vehicle. This was revealed by their positioning and speed, and also apparent in the verbal expressions, especially the positive remarks on the situation and conditions. However, the perceived comfort with lane markings present was actually lower than when they were missing. Cyclist type (slow, moderate, or fast) matters with the self-reported faster cyclists being more prone to stop to the right than the slower one.     

Promoting political empowerment: evaluation of an intervention with university students

The aim of this research is to examine the effects of an intervention, focusing on the development of political empowerment, with university students. Undergraduates were randomly assigned to one of two conditions (intervention/control) and were surveyed at two time points: before implementation of the intervention and upon completion of the intervention (or the equivalent two semester period). ANCOVA analyses reveal that individuals who participated in the empowering intervention had increased feelings of political commitment and a decreased sense of political efficacy compared to individuals who were randomly assigned to a waiting list/control group. Finally, limitations of this study are discussed and suggestions for future research are presented.     

Liberalism and the Privatised Family: The Legacy of Rousseau

This article argues that the intellectual legacy of Rousseau is at the root of the failure of 20th century egalitarian theorists such as Rawls and Dworkin to engage intellectually with feminist theorists working within the liberal tradition. Through an extended critique of Rousseau’s delineation of the relationship between liberal citizenship and the private family, it argues that the failure of such liberal theorists to take gender hierarchy seriously is a consequence of their attempt to place the private family outside the sphere not only of politics, but also of justice.     

Use of newsletters to promote environmental political action: an experimental analysis

The managers of beach businesses were randomly assigned to receive no intervention or two newsletters per week for 6 weeks that presented economic consequences of damage to coastal water quality and how to contact politicians. The percentage of proenvironmental political contacts was significantly greater in the experimental (newsletter) group than in the control group. Logistical regression showed that contacts in the newsletter group were more than five times that of controls after adjusting for history of contacts and predisposition to take such action. Results suggest that the intervention can promote political action that could influence environmental policies and human health.     

Emancipatory responses to oppression: the template of land-use planning and the Old Order Amish of Ontario

In this paper I discuss the clash of values between the Old Order Amish community of Ontario and the dominant social paradigm in agriculture. Land-use and agricultural regulations, designed for an industrial style of agriculture, are experienced as a threat to the survival of the Old Order Amish agricultural social economy and community. The paper describes how I have worked with the Old Order Amish to respond to these challenges and to create public policies that will allow them to maintain their human and agricultural diversity and small-scale sustainable farm practices. Four case studies illuminating the oppressive land-use regulations along with the emancipatory responses to the oppression are examined. The social transformation themes include principles and processes for community psychologists, land-use planners, and community economic development practitioners to consider. The article has heuristic value for a practice-based approach to social change.

Psychological Safety and Appreciation of Differences in Counselor Training Programs: Examining Religion,Spirituality, and Political Beliefs

This study focused on the extent to which religion, spirituality, and political beliefs predicted counseling students' perceptions of psychological safety and appreciation of differences in their programs. The authors used hierarchical regression models to analyze data from 264 students from 4 different institutions. Results indicated that student age, political conservatism, extrinsic religiosity, and intrinsic spirituality were significant predictors of perceived psychological safety and appreciation of differences. The authors discuss implications of these findings.     

A calibration explanation of serial position effects in evaluative judgments

Judges often evaluate stimulus series on dimensions for which no physical scale exists; for example, when judging academic ability in oral examinations. We propose that judges deal with this problem by calibrating an internal judgment scale that maps stimulus input onto available judgment categories. This calibration process implies serial position effects: Judges should initially avoid extreme categories, because using extreme categories reduces judgmental degrees of freedom, thereby increasing the possibility of internal consistency violations. In four experiments, we show that judgments become indeed more extreme later in a series of judgments. Judges evaluated the same good (poor) performances more positive (negative) at the end of a sequence compared to the beginning. Judges’ expertise did not prevent the effect, but allowing end-of-sequence judgments reduced serial position effects. We discuss the implications and possible remedies of these calibration effects on judgment extremity.     

左右半脸及其位置对面孔吸引力的影响

本研究将拼嵌技术（chimera technique）和融合技术（Morph tech—nique）结合起来,制作新形式的面孔刺激,将“刺激”和“位置”分离并分别操纵,检验了左右半脸及其位置对面孔吸引力的影响。实验结果显示：（1）“刺激”和“位置”都会影响面孔吸引力;（2）“刺激”的影响是直接的,具体表现为右半脸不论呈现在面孔的左侧还是右侧,其吸引力总是高于左半脸的吸引力;（3）“位置”的影响模式较为复杂,具体表现为左右半脸在原始位置呈现时（右丰脸呈现在右侧,左半脸呈现在左侧）,其吸引力总是高于镜像位置。
