The purpose of this study is to compare field investigative interviews of children (FIIC) with three different legal outcomes in child sexual abuse cases: (i) insufficient evidence to proceed (IEP); (ii) convictions; or (iii) acquittals by the court. One hundred FIIC were divided into one of the three outcome possibilities. Amongst the female interviewees older than 10 years, there were no cases of acquittals and the convicted cases were over-represented. The children's response to open questions was found to be the main difference between the three FIIC outcomes. The responses to these open questions were 1.9 and 2.3 times longer in the convicted cases compared to acquittals and IEP. Possible explanations for the result are discussed.

Whether people compete or cooperate with each other has consequences for their own performance and that of organizations. To explain why people compete or cooperate, previous research has focused on two main factors: situational outcome structures and personality types. Here, we propose that—above and beyond these two factors—situational cues, such as the format in which people receive feedback, strongly affect whether they act competitively, cooperatively, or individualistically. Results of a laboratory experiment support our theorizing: After receiving ranking feedback, both students and experienced managers treated group situations with cooperative outcome structures as competitive and were in consequence willing to forgo guaranteed financial gains to pursue a—financially irrelevant—better rank. Conversely, in dilemma situations, feedback based on the joint group outcome led to more cooperation than ranking feedback. Our study contributes to research on competition, cooperation, interdependence theory, forced ranking, and the design of information environments.  相似文献

The paper elaborates two points: i) There is no principal opposition between predicate logic and adherence to subject-predicate form, ii) Aristotle's treatment of quantifiers fits well into a modern study of generalized quantifiers.To the memory of Jerzy Supecki  相似文献

The purpose of this note is to formulate some weaker versions of the so called Ramsey test that do not entail the following unacceptable consequenceIf A and C are already accepted in K, then if A, then C is also accepted in K. and to show that these versions still lead to the same triviality result when combined with a preservation criterion.  相似文献

This project explores what dreams might reveal about the collective psyche’s response to the COVID-19 pandemic in its first year, before the development of vaccines. A brief survey, distributed to Jungian colleagues and organizations, and to various social media sites, invited people to submit online a dream related to the COVID-19 pandemic. Four hundred and thirty-six dreams were submitted. Forty additional Russian dreams were collected and submitted by Russian colleagues. Using qualitative research methods based on phenomenological hermeneutics, the researchers categorized and counted the range of COVID imagery. In addition, the researchers describe a range of psychic responses to the pandemic, including horror, grief, sickness, social discord, and violence, but also images of healing and transformation, increased sense of community, and spiritual renewal. Several healing nightmares are presented. Healing alchemical and anima/animus imagery is described. Twelve dreams are introduced and presented. It is concluded that the collective psyche, rooted in the Self, is a healing resource for social and cultural trauma. This project supports Beradt’s (1968) inspirational study of dreaming in Nazi Germany, as well as recent studies of COVID-related dreams and recent publications on the social nature of dreaming.  相似文献

Lowering the voting age from 18 to 16 years has recently been a hot topic of the political debate in many democratic countries. This study investigated whether the voting quality of 16–17-year-olds is inferior to that of the voting population. Shortly before the 2021 German federal election, two samples, representative for age and gender, indicated personal preferences about various political issues and weighted them according to importance, allowing for the calculation of individual expected values for political parties. Participants then indicated their voting choice. These choices were normatively correct when individuals voted for the party that best reflected their preferences, that is, the one maximizing the expected value. Results show that the voting decisions of 16–17-year-olds were as good as those by eligible voters. The study indicates that the exclusion of 16–17-year-old Germans in democratic elections cannot be justified by their lack of decision-making ability.  相似文献
