The Intensity Effect in Adolescent Close Friendships: Implications for Aggressive and Depressive Symptomatology

This study examined the effect of close friendship intensity as a potential amplifier of an adolescent's preexisting tendencies toward depressive and aggressive symptoms. A diverse community sample of 170 adolescents and their closest friends was assessed via multiple methods, and adolescents were followed from age 16 to 17. Results supported the hypothesized effect, with more intense close friendships interacting with higher baseline levels of behavioral symptoms to predict greater relative increases in symptoms over time. Effects were observed for both depressive and aggressive symptoms, and appeared with respect to multiple observational measures of friendship intensity. Findings are interpreted as suggesting that seemingly disparate phenomena (e.g., co‐rumination for depression and deviancy‐training for aggression) may both be dependent upon the intensity of the adolescent's social connections.     

Managerial Responses to Online Reviews: A Text Analytics Approach

This study tests the effects of online managerial responses and returning customers’ future satisfaction (measured as review ratings) by performing social media text analytics on a hotel sample. Essentially, this paper provides insight into meaningful differences in future ratings between responding and non‐responding hotels, as well as differences in response styles between ratings improvement and non‐improvement. The results indicate that: (1) subsequent ratings are higher if customers receive responses to their previous online reviews; (2) increase in ratings is more significant among low‐satisfaction customers, and a decrease in ratings is mitigated if responses are provided; (3) responding to loyal customers – those who have visited and rated the same hotel more than three times – has a limited impact on ratings; (4) responses are longer and sentiment is slightly lower in scenarios where subsequent ratings are improved, but there is no significant difference in the effect of response speed between the two groups; (5) changes in ratings also affect styles of responding to current reviews – if customer satisfaction has improved, response length tends to be shorter and sentiment level tends to be higher. The findings offer both theoretical and managerial implications by demonstrating the utility of social media text analytics.     

Homosexuality,Religion, and Science: Moral Authority and the Persistence of Negative Attitudes*

The liberalization of attitudes toward homosexuality in the United States over the past 30 years is well documented. Despite these changes, substantial resistance to equality for gay men and lesbians remains. Previous studies indicate that beliefs about the etiology of homosexuality are central to this discussion. Those who believe homosexuality is innate are more favorable, while those who believe it is the result of a choice are more negative. Moreover, experimental research indicates that those with negative views actually become more opposed when a natural explanation is proposed. This study highlights the importance of perceived sources of epistemic and moral authority for understanding views of homosexuality. Using stances on culturally controversial issues involving “science and religion” as indicators of where individuals place authority, we outline the connection between perceptions of moral authority and attributions about homosexuality. Analyses of a national survey of American adults show that, net of controls, one’s stance on moral authority is the strongest predictor of attributions about whether homosexuality is chosen or innate.     

Quality of College Life (QCL) of Students: Further Validation of a Measure of Well-being

This paper reports a study designed to further validate a measure of quality of college life (QCL) of university students (Sirgy, Grzeskowiak, Rahtz, Soc Indic Res 80(2), 343–360, 2007). Two studies were conducted: a replication study and an extension study. The replication study involved surveys of 10 different college campuses in different countries. The results of the replication study provided additional nomological (predictive) validation support of the measure based on a theoretical model mapping out the antecedents and consequences of satisfaction with college life. With respect to the extension study, the focus was to further test the nomological validity of the QCL measure by arguing and empirically demonstrating that the consequence of QCL is life satisfaction. The extension study involved a survey of three college campuses in different countries. The results were also supportive of the nomological validity of the QCL measure.     

Ethnic Community and Ethnic Boundaries in a “Sauce‐Scented Neighborhood”1

This article investigates the problem of ethnic boundary making in a changing context. Our case is Boston’s North End, a historically Italian neighborhood undergoing changes to its social and physical environment, making the ethnic definition of neighborhood identity and belonging more difficult though not less salient. Consequently, participants in the workings of the neighborhood—residents, business owners, politicians—face challenges of both boundary placement (who is Italian and who is not?), as well as cultural content (what does it mean to be “Italian”?). Rather than viewing Italian ethnicity as simply weakening over time, we argue that the North End shows ethnicity is in a stage of category divergence, where the still‐dominant ethnic identity is juxtaposed not against another ethnic out‐group, but at various times against boundaries of class and race, commercial and community values, even city political boundaries. Drawing on ethnographic research and in‐depth interviews, we describe three group identity frames that illustrate these processes and reveal how Italian ethnicity continues to animate discourse and action in the neighborhood.     

Trust,perceptions of corruption,and demand for regulation: Evidence from post-socialist countries

While the tradeoff between market failure and government failure has been explored both theoretically and in practical policy design, the question of whether this trade-off appears in the calculus of citizens’ demands for government regulation remains underexplored. We first clarify the channels through which concerns for market failure, as proxied by trust in market participants, and concerns for government failure, as proxied by perceptions of corruption, jointly affect individuals’ demand for government regulation. We then investigate these effects empirically, using data from post-socialist countries. Our analysis confirms the previously established result that trust has a negative effect on demand for regulation. Perceived corruption, however, affects demand for regulation primarily via a negative interaction effect with trust. Our findings suggest that, in post-socialist countries, both concerns for market failure and concerns for government failure are indeed in citizens’ minds and that concerns about the anticipated ‘grabbing-hand’ effect from government involvement are particularly salient.     

Radiological emergency response for community agencies with cognitive task analysis, risk analysis, and decision support framework

Radiological nuclear emergency responders must be able to coordinate evacuation and relief efforts following the release of radioactive material into populated areas. In order to respond quickly and effectively to a nuclear emergency, high-level coordination is needed between a number of large, independent organizations, including police, military, hazmat, and transportation authorities. Given the complexity, scale, time-pressure, and potential negative consequences inherent in radiological emergency responses, tracking and communicating information that will assist decision makers during a crisis is crucial. The emergency response team at the Angra dos Reis nuclear power facility, located outside of Rio de Janeiro, Brazil, presently conducts emergency response simulations once every two years to prepare organizational leaders for real-life emergency situations. However, current exercises are conducted without the aid of electronic or software tools, resulting in possible cognitive overload and delays in decision-making. This paper describes the development of a decision support system employing systems methodologies, including cognitive task analysis and human-machine interface design. The decision support system can aid the coordination team by automating cognitive functions and improving information sharing. A prototype of the design will be evaluated by plant officials in Brazil and incorporated to a future trial run of a response simulation.     

Potential impacts of emerald ash borer invasion on biogeochemical and water cycling in residential landscapes across a metropolitan region

Trees provide important ecological services in cities, yet the vulnerability of the urban forest to massive tree losses from pest outbreaks could threaten those services, with unknown environmental consequences. The outbreak of emerald ash borer is an imminent threat to the ash population in North America. In the Minneapolis?CSaint Paul, Minnesota, metropolitan area, ash trees are present in 50?% of residential landscapes in Ramsey and Anoka Counties. We used a large survey of household activities, a tree inventory, a Household Flux Calculator accounting tool, and a set of annual evapotranspiration measurements, to quantify the current carbon, nitrogen, and phosphorus storage in ash trees, the cycling of these elements, and the total evapotranspiration from ash trees in residential areas in the metropolitan region. Ash represented 6?% of the trees in residential areas and the removal of the entire ash population would correspondingly reduce net primary production and carbon sequestration by only a few percent and would have negligible effects on losses of nitrogen and phosphorus from residential landscapes. Similarly, the effects of ash loss on the hydrologic cycle would be minimal and would depend largely on management choices for the ground currently underneath ash tree canopies. Overall, the percentage change in biogeochemical and hydrological fluxes corresponded closely with the percent of the total urban tree population that was represented by ash, suggesting that areas with higher densities of ash would experience correspondingly larger effects. A hypothetical tree replacement scenario with similar broadleaf species was determined to be likely to re-establish the original biogeochemical and hydrological conditions once the replacement trees reach maturity.     

The Organization of Wariness of Heights in Experienced Crawlers

Most infants with more than 6 weeks of crawling experience completely avoid the deep side of a visual cliff ( Campos, Bertenthal, & Kermoian, 1992 ; Gibson & Walk, 1960 ). However, some experienced crawlers do move onto the transparent surface suspended several feet above the ground. An important question is whether these nonavoiders lack wariness of heights or whether they have a qualitatively different way of showing their wariness than do avoiders of the deep side. The current study addressed this question by measuring heart rate (HR) acceleration upon being lowered on the deep and shallow sides of the visual cliff, latency to crawl toward the mother, and tactile exploration of the cliff surface. Nonavoiders and avoiders had indistinguishable patterns of HR acceleration, showing greater HR acceleration when lowered onto the deep than when lowered onto the shallow side of the cliff. Nonavoiders also showed more tactile exploration and longer latencies than did a comparable group of infants tested on the shallow side. This study illustrates how the same emotion, wariness of heights, can be shown by qualitatively different behaviors, all serving the same function of protecting the individual from falling over a drop‐off.
