Intraspecific aggression in male hamsters is inhibited by intrahypothalamic vasopressin-receptor antagonist

The present study examines the effect of the arginine vasopressin (AVP) receptor antagonist, d(CH₂)₅Tyr(Me)AVP, on intraspecific aggression between pairs of male Golden hamsters in a neutral territory. Subjects drawn from a group of 24 animals were paired once each with novel partners from the group under each of three experimental conditions: 1) both members of a pair were microinjected into the anterior hypothalamus with saline (S/S), 2) one member of a pair was microinjected with AVP-receptor antagonist and its partner with saline (A/S), and 3) both members of a pair were microinjected with AVP-receptor antagonist (A/A). There were significantly (P < .01) fewer attacks during encounters between pairs of hamsters in the A/A condition compared to pairs in the A/S condition. Similarly, pairs in the A/S condition attacked significantly (P < .025) less often than pairs of hamsters in the S/S condition. These results confirm our earlier work showing that AVP-receptor antagonist reduces intraspecific aggression. In addition, saline-treated hamsters initiated significantly (P < .001) fewer attacks toward antagonist treated hamsters than would have been predicted if their opponent was not drug treated. These latter results suggest that hamsters microinjected into the anterior hypothalamus with an AVP-receptor antagonist also elicit less aggression from conspecifics.     

The Effectiveness of Victim Resistance Strategies against Stranger Child Abduction: An Analysis of Attempted and Completed Cases

Existing research, policy information, and materials intended to teach child safety assumes that certain behaviours will protect children in the event that a stranger tries to abduct them. However, there is little empirical basis for these assumptions. This paper examines the effectiveness of strategies thought to increase the likelihood that a child will be able to resist an attempted stranger child abduction event. Seventy‐eight cases of stranger child abduction that occurred in the UK between 1988 and 2014, including 25 attempted cases and 53 completed cases, were examined in order to ascertain the relative prevalence of various resistance types and to assess their effectiveness of six key resistance strategies based on whether the presence or absence affected the outcome of the abduction. Results show that direct, unequivocal verbal resistance, running away, and a composite approach where the victim runs away, calls for help, and reports the offence were highly effective means of resisting an offender, whereas physical resistance, indirect verbal resistance, and non‐resistance were not effective. Female victims were almost twice as likely to employ any kind of resistance strategy against an offender as male victims were. The implications of these findings for augmenting ways in which children are taught about safety are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Mobilizing cause supporters through group‐based interaction

Collective action expresses group‐based identities, formed by supporters seeking to further particular social causes. While the development of groups linked to action necessitates interaction among supporters, little research has examined how these groups form. Utilizing responses of supporters who participated in 1 of 29 action‐planning sessions, this research presents an initial attempt to identify the ingredients important to this process. It shows that to the extent that the actions agreed on in the course of group interactions were seen as capable of making a difference (action efficacy), and worthy of public expression (action voice), supporters’ group‐based identification was enhanced. This in turn increased their willingness to engage in collective action. Practical implications and avenues for future research to understand the mobilization process are discussed.     

Assessing the Utility of Compound Trait Estimates of Narrow Personality Traits

It has been argued that approximations of narrow traits can be made through linear combinations of broad traits such as the Big Five personality traits. Indeed, Hough and Ones (2001 Hough, L. M., &; Ones, D. S. (2001). The structure, measurement, validity, &; use of personality variables in industrial, work, and organizational psychology. In N. Anderson, D. S. Ones, H. K. Sinangil, &; C Viswesvaran (Eds.), Handbook of industrial, work, and organizational psychology (Vol. 1, pp. 233–277). London, UK: Sage.[Crossref] , [Google Scholar]) used a qualitative analysis of scale content to arrive at a taxonomy of how Big Five traits might be combined to approximate various narrow traits. However, the utility of such compound trait approximations has yet to be established beyond specific cases such as integrity and customer service orientation. Using data from the Eugene-Springfield Community Sample (Goldberg, 2008 Goldberg, L. R. (2008). The Eugene-Springfield community sample: Information available from the research participants. Eugene: Oregon Research Institute. [Google Scholar]), we explore the ability of linear composites of scores on Big Five traits to approximate scores on 127 narrow trait measures from 5 well-known non-Big-Five omnibus measures of personality. Our findings indicate that individuals' standing on more than 30 narrow traits can be well estimated from 3 different types of linear composites of scores on Big Five traits without a substantial sacrifice in criterion validity. We discuss theoretical accounts for why such relationships exist as well as the theoretical and practical implications of these findings for researchers and practitioners.     

Fantasy Objects: The Perception of Safety of Emergency Shelter in Place Kits

Using interview data (n = 30) of residents in Calhoun County, Alabama, we examine the meaning respondents give to the objects (shelter-in-place kits) disseminated to residents in order to manage risk of accidents from Anniston Army Depot’s Chemical Weapons storage and incinerator activities. Our research builds on previous research examining how organizations engage in ‘fantasy planning,’ where they create plans that objectively do not increase safety but do create the perception of safety within the organization and especially the public.     

The Effects of Low Self-Control and Desire-for-Control on White-Collar Offending: A Replication

To further our understanding of the similarities and differences between street-level and white-collar offending, two personality traits were used to predict offending intentions. The independent and joint roles of low self-control and desire-for-control on intentions to engage in embezzlement, credit card fraud, and shoplifting were assessed. Findings suggested that while low self-control was predictive of intentions to offend, the impact of desire-for-control varied based on the respondent’s level of self-control. In contrast to prior studies, desire-for-control reduced offending intentions, but only among those with high self-control. A discussion of these findings is offered, along with study limitations and future directions.     

Protective Factors for Deviance: A Comparison of Rural and Urban Youth

Based on data from the 2010, 2012, and 2014 Communities that Care Youth Survey, the authors examine the protective factors associated with rural and urban students in grades 6 through 12 across several domains. This research is based on the literature that associates rural areas with a more protective environment and resulting lower rates of deviance. Findings were mixed, but overall rural youth had higher protective factor scores. A summary of all 84 protective factor scores follows: 26 factors shown no significant different between rural and urban students; on 42 protective factors rural youth had higher scores, as opposed to urban youth with higher protective scores on only 16 factors. Implications of findings for crime and delinquency are discussed.
