Effect of consumption choices on fluxes of carbon,nitrogen and phosphorus through households

Households are an important scale of analysis for human ecosystems because they are a major source of pollutants and could thus be a new focus for pollution management, particularly for education-based source reduction strategies. The household is also a meaningful unit for analysis of human ecosystems, being common to all human cultures. This study develops a Household Flux Calculator (HFC) to compute C, N, and P fluxes for scenarios intended to represent three levels of household consumption: low, typical, and high. All three scenarios were developed for suburban households with two adults and two children in the Minneapolis-St. Paul (Twin Cities) metropolitan area, Minnesota. Calculated ratios of fluxes between high and low consumption households were 3.5:1 for C, 2.7:1 for N and 1.4:1 for P. Results suggest a high level of discretionary consumption that could be reduced without a substantial reduction in standard of living. Thus, modest changes in behavior in high consumption households would greatly reduce fluxes of C, N, and P without major changes in lifestyle.

Officer friendly and the tough cop:gays and lesbians navigate homophobia and policing

Despite attempts to expand social diversity, policing is still dominated by a white, masculine, heterosexual ethos. As a consequence, employment of lesbians and gay men as police officers may be especially threatening to members of this occupation. Within the context of potential hostility and homophobia, nontraditional officers must negotiate their contradictory presence on the police force. This paper investigates that negotiation. Using the Bem Sex Role Inventory and open-ended survey data from a sample of "out" and "closeted" gay and lesbian police officers, we ask how gays and lesbians manage their images as "good cops" in the face of gender norm violations associated with their sexual orientation. Our findings indicate that masculinity and femininity do not hold together in a cohesive, dichotomous manner for these officers. Instead, other characteristics that enhance policing are emphasized to support their occupational competence. These officers see themselves as "good cops." The gendered/sexualized character of their self-perceptions appears to matter less than the context of the job, more than for a comparison sample of heterosexual police officers. We conclude that although gay and lesbian officers see their sexuality as an occupational asset, they are also likely to work harder to prove themselves as crime fighters.     

“Step Up and Be a Man in a Different Manner”: Unemployed Men Reframing Masculinity

Although the percentage of women working for pay outside the home has steadily increased over time, traditional gender frames still valorize the male breadwinner and the female caregiver, and most households remain organized along gender lines. Recently, however, the global economic crisis significantly altered the structure of work in the United States. Beginning in 2007, “breadwinning” men began to lose jobs in multiple economic sectors. Because work is tied to masculine identities, these men suffered psychologically as well as economically. Using data from 40 semistructured intensive interviews with diverse men, we examine their strategies for coping. These men reframed household labor as work befitting men, even while reiterating traditional gender ideals. They began to adopt gender‐flexible schema in response to structural changes beyond their control.     

Infants use contextual memory to attend and learn in naturalistic scenes

Infants encounter new objects and learn about object features in relation to a rich and detailed visuospatial context. Using a contextual cueing task, recent work showed that 6- and 10-month-old infants search more efficiently for target objects in repeated rather than novel visuospatial contexts (i.e., arrays of shapes on a blank background). Here, we investigate whether infants' sensitivity to visuospatial context scales up to more complex and potentially more distracting, naturalistic scenes. In an eye-tracking task, 8-month-olds searched for a novel target object in colorful photographs of everyday environments (e.g., bedrooms and kitchens). Repeated (“Old”) contexts co-varied with target locations, such that the target object appeared in exactly the same location on the same scene, while varying (“New”) contexts contained target objects placed in different counterbalanced locations across a variety of scenes. Infants exhibited faster search times, more anticipation of target animation, and longer looking at targets that appeared in Old relative to New contexts. In a subsequent memory test, infants showed better recognition of label-object pairings for target objects that had appeared in Old, rather than New, contexts. These results indicate that infants can use visuospatial contextual information in complex naturalistic scenes to facilitate memory-guided attention and learning of object-paired labels.     

Adolescents’ perceptions of social risk and prosocial tendencies: Developmental change and individual differences

Many prosocial behaviors involve social risks such as speaking out against a popular opinion, bias, group norm, or authority. However, little is known about whether adolescents’ prosocial tendencies develop over time with their perceptions of social risks. This accelerated longitudinal study used within-subject growth-curve analyses to test the link between adolescents' prosocial tendencies and social risk perceptions. Adolescents completed self-reports annually for 3 years (N = 893; M_age = 12.30 years, 10–14 years at Wave 1, and 10–17 years across the full study period; 50% girls, 33% White non-Latinx, 27% Latinx, 20% African American, 20% mixed/other race). The association between social risk tolerance and prosocial tendencies changed significantly across adolescence. Specifically, for younger adolescents, more prosocial tendencies were associated significantly with less social risk tolerance, whereas for relatively older adolescents, more prosocial tendencies were associated marginally with more social risk tolerance. Additional individual differences by empathy (but not sensation seeking) emerged. These findings suggest that prosocial tendencies across adolescence may be associated with an underlying ability to tolerate social risks.     

Preschoolers’ responses to prosocial opportunities during naturalistic interactions with peers: A cross-cultural comparison

The goal of this study was to better understand similarities and differences in preschool children's expression of needs and prosocial responsiveness to peers’ needs across two culturally distinct contexts. Preschoolers were observed in a semi-naturalistic design across rural Mexico and urban Canada, wherein they were instructed to build a tower with blocks. Three- to 6-year-olds (N = 306; 48% female) were divided into 64 peer groups. We coded for children's expression of needs (instrumental, material, or emotional), responses to prosocial opportunities (prosociality, denial, or no response), prosociality without an apparent need (spontaneous prosociality), and types of prosocial behavior (helping, sharing, or comforting). While instrumental and material needs were expressed similarly across both samples, Tzotzil Maya children expressed fewer emotional needs than Canadian children. Failing to respond to others’ needs, followed by denial, were the most frequent need-provoked response in both countries; surprisingly, only 9% of needs received a prosocial response. Though need-provoked prosociality was rare in both cultural contexts, children engaged in considerable spontaneous prosociality which varied as a function of age, gender, and cultural context. Lastly, Canadian more than Tzotzil Maya children denied emotional and instrumental needs (but not material needs). The findings inform how cultural practices may shape the presentation of needs and prosocial responsiveness in peer interactions.
