Nanotechnology: The Next Challenge for Organics
Nanotechnology is the fast growing science of the ultra small; it is creating engineered particles in the size range 1 to 100 nanometres. At this size, materials exhibit novel behaviours. Nanotechnology is a rapidly expanding multibillion dollar industry, with research being heavily promoted by governments, and especially the US. Nanoscale materials are already incorporated into more than 580 consumer products, including food, packaging, cosmetics, clothing and paint. Nanotechnology has been cited as the foundation of a new âadvanced agricultureâ. This technology is advancing without nano-specific regulation and without labelling while, at the same time, public confidence in government regulatory agencies, and in the safety of the food supply, is declining. There is an opportunity, perhaps an imperative, for the organic community to take the initiative to develop standards to exclude engineered nanoparticles from organic products, just as GMOs have been excluded previously
College Studentsâ Perceptions of Barriers to Bystander Intervention
Sexual violence is a major problem on college campuses and is associated with a range of negative health consequences for victims. Teaching students to intervene as prosocial bystanders has become a common element of sexual assault prevention efforts; although these programs have demonstrated positive effects on participantsâ beliefs and knowledge, their impact on actual behavior is weaker. Understanding the factors that inhibit intervening in risky situations may enhance the effectiveness of bystander programs by identifying material that addresses these barriers. A sample of 281 first-year college students indicated whether they had encountered 10 situations that may present elevated risk of sexual or physical assault since arriving on campus, and if so, whether they had done something to intervene. If they had not intervened, they were asked to identify the barriers that had inhibited them. Participants also completed measures of two factors proposed to predict bystander behavior, self-efficacy and emotion regulation. A majority of participants intervened in most of the situations, but only 27% of participants intervened in every situation they encountered. Men and women differed in the barriers they identified most frequently across situations, with men endorsing Perceived Responsibility more often than women, and women reporting Skill Deficits more often than men. Neither men nor women perceived Audience Inhibition to be a significant barrier; it was salient in only one of the 10 situations. Students higher in global bystander self-efficacy were more likely to intervene and less likely to report barriers related to skill deficits and perceived responsibility. These results suggest that existing bystander intervention programs efforts can be improved by fostering a greater sense of collective responsibility in students and teaching specific intervention behaviors
Exploring the Role of Attachment Style in the Relation between Family Aggression and Abuse in Adolescent Dating Relationships
This study investigated romantic attachment style as a potential moderator of the link between family aggression and dating aggression, and examined its relations with documented mediators of the impact of interparental conďŹict on dating behavior: attitudes about the justiďŹability of aggression and anger regulation. Participants were 391 ethnically diverse 14-to 18-year-olds (52% female). Attachment style was a signiďŹcant moderator for boys and girls, but the pattern of results differed by gender. In general, attachment anxiety was a more consistent predictor than avoidance of boysâ dating aggression, cognitions, and emotions, whereas anxiety and avoidance both acted as signiďŹcant moderators for girls. These results suggest that youthsâ romantic attachment style can amplify or attenuate the impact of family aggression on abusive behavior in dating relationships by inďŹuencing their beliefs about the acceptability of aggression and their ability to regulate anger
Caregiver Behaviors Associated With Emotion Regulation in High-Risk Preschoolers
Children who witness violence are at risk for developing a range of developmental problems, including deficits in understanding and regulating. The ability to adaptively manage emotions is associated with childrenâs mental health and their social and academic competence; however, little is known about how parents of at-risk youth can foster the healthy development of emotion regulation. The current study aimed to identify specific parenting practices associated with adaptive emotion regulation in at-risk preschoolers. Multimethod, multi-informant data were collected from 124 caregiver-child dyads from Head Start programs. Results indicated that interparental aggression was negatively associated with caregiversâ and childrenâs emotion regulation, but there were specific caregiver behaviors that moderated the association between interparental aggression and childrenâs emotion regulation. Specifically, care- giversâ sensitivity to childrenâs emotions during play, listening effectively to childrenâs expression of sadness, and their own capacity for emotion regulation buffered the association between exposure to interparental aggression and childrenâs emotion regulation. These findings provide practical insight into how parents can promote resilience in children exposed to violence by fostering healthy emotional regulation

A time series analysis of wages in deregulated industries: A study of motor carriage and rail
Using time series techniques, we contrast the impact of deregulation in trucking and rail labor markets. During regulation both labor markets were characterized by wages considerab y higher than manufacturing wages. In fact, trucking and rail wages had a stable, deterministic relationship prior to deregulation. After deregulation, however, the mean trucking wages fell considerably, approaching manufacturing wages, while rail wages remained relatively constant. We also find that deregulationâs negative impact on trucking wages was nondiscrete and occurred primarily between 1980 and 1984.deregulation, trucking, rail
Framework Development
Building on a prior reports, surveys, and workshops, this NSF-funded GER Framework project engaged ~200 geoscience educators and researchers through a sequenced series of virtual and face-to-face events to share ideas, gain feedback, and create and revise priority research questions, or Grand Challenges , that span 10 geoscience education research themes. For each theme, several Grand Challenges and recommended strategies have been proposed by the community. This framework development chapter describes the underlying project goal, its objectives, and its vision. It also outlines the processes used to develop the Framework and the intended scope and audience
Nano-in-food - Threat or Opportunity for Organic Food?
Nanotechnology is creating engineered particles in the size range 1 to 100 nanometers. At the nano-scale, materials exhibit novel behaviours. Nine billion dollars is currently invested annually in nano-research, with the explicit intention of rapid commercialisation, including food and agriculture applications. Nanotechnology is currently unregulated, and nano-products are not required to be labelled. Health, safety and ecological aspects are poorly understood, and there have been calls for a moratorium. Two consumer surveys indicate that public awareness of nanotechnology is low, there is concern that the risks exceed the benefits, that food safety is declining along with declining confidence in regulatory authorities. A majority of respondents (65%) are concerned about side effects, and that nano-products should be labelled (71%), and only 7% reported they would purchase nano-food. There is an opportunity, for the organic community to take the initiative to develop standards to exclude engineered nanoparticles from organic products. Such a step will service both the organic community and the otherwise nano-averse consumers - just as GMOs have been excluded previously
