Limits on Composition of Conceptual Operations in 9‐Month‐Olds

Complex systems are often built from a relatively small set of basic features or operations that can be combined in myriad ways. We investigated the developmental origins of this compositional architecture in 9‐month‐old infants, extending recent work that demonstrated rudimentary compositional abilities in preschoolers. Infants viewed two separate object‐occlusion events that depicted a single‐feature‐change operation. They were then tested with a combined operation to determine whether they expected the outcome of the two feature changes, even though this combination was unfamiliar. In contrast to preschoolers, infants did not appear to predictively compose these simple feature‐change operations. A second experiment demonstrated the ability of infants to track two operations when not combined. The failure to compose basic operations is consistent with limitations on object tracking and early numerical cognition (Feigenson & Yamaguchi, Infancy, 2009, 14, 244). We suggest that these results can be unified via a general principle: Infants have difficulty with multiple updates to a representation of an unobservable.     

Bullying victimization,negative emotions,and substance use: utilizing general strain theory to examine the undesirable outcomes of childhood bullying victimization in adolescence and young adulthood

Bullying victimization has been directly associated with a variety of negative outcomes, but there are still many unknowns as to how deleterious emotional states resulting from victimization influence other undesirable events. The current study draws on Agnew’s general strain theory to examine multiple outcomes of youth victimized by repeated bullying prior to adolescence. Data from the National Longitudinal Survey of Youth 1997 were used to examine indicators of diminished moods and negative emotions on substance use for bullying victims in adolescence and again during young adulthood. Findings from various LISERL models indicate that bullying victimization directly increases diminished moods for males and females in adolescence. Additionally, childhood bullying victimization directly increases substance use in adolescence and young adulthood for males but not females. Finally, diminished moods in adolescence and negative emotions in young adulthood increase substance use for females but not for males. Policy implications and limitations for this analysis are discussed.     

Vulvovaginal Pain from a Fear-Avoidance Perspective: A Prospective Study Among Female University Students in Sweden

Objectives: To examine how fear-avoidance influences vulvovaginal pain and sexual function over time. Method: At baseline and at 10-month follow-up, self-report measures for sexual and fear avoidance factors were obtained from 483 female university students with and without self-reported vulvovaginal pain. Results: Individuals with pain at both times reported lower sexual function, and higher levels of fear-avoidance compared to the pain-free group. Fear-avoidance beliefs predicted the occurrence of vulvovaginal pain at follow up and the level of pain intensity. Conclusion: The results points to the relevance of the components of the fear-avoidance model in vulvovaginal pain over time.     

The State as a Norm‐Builder? The Take‐up of Parental Leave in Norway and Sweden

This study shows that although Norway and Sweden have rather similar family policies, the seemingly small differences that exist reflect different national ideals of care, and these differences encourage parents to employ different gendered moral rationalities. However, Sweden's ideal of ‘equal‐sharing/professional care’, encourages fathers to take longer leaves than the Norwegian ideal of ‘partial sharing plus choosing between professional or parental care’. Given their different national ideals of caring, different gendered moral rationalities emerge. While in Norway the dominant gendered moral rationality among our interviewees is ‘man‐doing‐his‐duty’, in Sweden two different rationalities arise: the ‘breastfeeding‐plus‐sharing’ rationality and the ‘male‐opt‐out’. This conclusion is based on 60 interviews with mothers and fathers in Oslo and Stockholm.     

A Dryland Cropping Revolution? Linking an Emerging Soil Health Paradigm with Shifting Social Fields among Wheat Growers of the High Plains

Once reliant on year-long periods of unvegetated fallow, dryland farmers are reaping environmental and economic benefits by replacing fallow with a crop, a practice called cropping system intensification. However, in the U.S. High Plains, transitions to intensified cropping systems have been slow relative to other regions, and cropping systems have stratified into varying degrees of intensity. Prior attempts to explain the wave of cropping system intensification have largely focused on simple economic rationales, and thus we lack a critical understanding of the social dynamics underlying the revolution in semi-arid cropping systems. We examined the motivations, perceptions, and social interactions of dryland farmers that practice different levels of cropping system intensity in Colorado and Nebraska. Building on Carolan's application of Bourdieusian social fields to agriculture, we identify overlapping fields expressed among interviewees. While these fields are reflected in farms' different degrees of intensification, they can be used to help identify and locate farmers associated with the emerging soil health (or regenerative agriculture) movement. The paper concludes by identifying strategies for change, some which would serve to reshape social fields, and others which leverage existing social positions and relationships to enable farmers to overcome the barriers constraining cropping system intensification.     

The Relationship of Problem Gambling to Criminal Behavior in a Sample of Canadian Male Federal Offenders

This article examines the prevalence of moderate and severe problem gambling in a sample of 254 incarcerated Canadian male federal offenders (completion rate of 39.0%). The prevalence of disordered gambling was measured using the PGSI, DSM-IV-TR, and SOGS that yielded estimates of 9.4%, 6.3%, and 13.0%, respectively. Severe problem gamblers were significantly more likely to have committed income producing offences, but were neither more nor less likely than other offenders to have committed violent offences. The majority of severe problem gamblers (65.2%) and a fifth of the moderate problem gamblers (20.0%) reported that their criminal activity was a result of their gambling (e.g., to pay off debts). Based on these findings there appears to be a need to offer problem gambling treatment services to offenders in order to help them break the cycle of gambling, debt and crime.     

Tipping as risk sharing

Tipping is often dismissed as an exception to the assumption of rational economic agents. This paper describes situations where tipping is, in fact, an effective mechanism for risk sharing and welfare improvement. When risk-averse customers purchase a service with uncertain quality, tipping can reduce the customer's exposure to risk by making part of the price of the service discretionary. These findings help explain why we tend to tip restaurant workers but not retail workers and why some high-risk service providers, such as lawyers and automobile mechanics, are not typically tipped.     

Domestic violence: analysis of a community safety alarm system

This paper presents the findings of an analysis of the trial period of a local authority community alarm system adapted to protect adult and child victims of domestic violence and enable them to remain living in their own homes. The system was augmented as a response to government guidance on promoting interagency initiatives to tackle the crime of domestic violence. Qualitative and quantitative research methods were employed to seek the perceptions and experiences of referrers, service users and potential service users in the context of the administration, resource implications and cost‐effectiveness of the new system. The evaluation discovered that potential service users were anxious about police and social services involvement in relation to child care. The system was considered to be protective, enabling women and children to remain in their own homes, and relatively cheap to operate. It has the potential to provide a deterrent to perpetrators and enhance interagency cooperation in protecting children, subject to further refinement and longer‐term evaluation.
