Driver compliance with stop signs at pedestrian crosswalks on a university campus.

Pedestrians on college campuses interact continuously with various motorized vehicles. Rates of compliance with stop signs at pedestrian crosswalks and noncomplying vehicles were monitored in spring 1996 on a large urban campus. The number of pedestrians, pedestrian clearance, type of vehicle, hour of day, and day of week were monitored at 3 pedestrian crosswalks. The overall compliance rate for stop signs was 22.8 per 100 vehicles, ranging from 1.4 per 100 for bicycles to 46.2 per 100 for commuter vans. Compliance increased to 53 per 100 vehicles when pedestrians were present in the crosswalk. Several differences in compliance rates were found among the observation sites. Lowest compliance was observed for bicycles and motorcycles. Pedestrians on this and other college campuses risk injuries because of violations of pedestrian right-of-way laws. The problem calls for appreciable educational efforts by college health personnel.     

Operationalizing environmental indicators for physical activity in older adults

This qualitative study describes environmental supports and barriers to physical activity in an older adult sample drawn from low- and high-walkable neighborhoods. Thirty-seven individuals age 55 and over were recruited and answered open-ended survey questions, with a subsample invited back to partake in a semistructured interview. Content analysis identified categories and themes linking perceptions of neighborhood-environment characteristics to activity. Emerging categories and themes did not differ across neighborhood walkability, so results are presented for both groups combined. Infrastructure was the most common category identified to encourage activity, specifically, well-maintained sidewalks, bike paths or lanes, and traffic control. Other categories of land use, landscape, and aesthetics were reported. Poorly maintained or missing sidewalks, crosswalks, bike paths or lanes, and traffic safety were categories that discouraged activity. In conclusion, the information obtained is helpful in solidifying which environmental characteristics are important to measure as they relate to activity behavior in an older adult population.     

Composition and conservation value of bird assemblages of urban ‘habitat islands’: Do pedestrian traffic and landscape variables exert an influence?

Urban forest fragments can potentially be ‘habitat islands’ for native birds, but pedestrian traffic could influence the composition and conservation value of their bird assemblages by reducing the representation of disturbance-sensitive species. Winter bird assemblages and pedestrian traffic rates were documented in twelve forested parks in suburban Melbourne, Australia. Native birds comprised 87% of sightings, but two exotic species were common. Bird species' distribution among the parks was significantly nested. However, park rank orders for bird assemblage nestedness and mean pedestrian traffic rate were not correlated and only one species' distribution was nested with respect to this variable. The observed correlation between park area and bird assemblage nestedness may have been partly due to passive sampling. Degree of isolation of parks influenced nestedness less than park area. Forested parks provided habitat for species that occur at intermediate to low densities in other suburban habitats and for ecological specialists otherwise rare in suburbia. Larger parks contained more species than, and many of the native species found in, smaller parks. However, smaller parks each had 25% of the native bird species inhabiting the suite of fragments and thus had both aesthetic value and some potential to enhance city-dwellers' awareness about biodiversity conservation.     

Passing Encounters East and West: Comparing Japanese and American Pedestrian Interactions

This study examined the microinteractions of pedestrians in Japan and in the United States as they walked past a confederate. Specifically, the effects of culture, condition (avoid, look-only, and look plus smile) and sex of confederate on glances, smiles, nods, and greetings by passing pedestrians were examined in a field study on over 1000 participants. The hypotheses of (1) lower responsiveness in Japanese pedestrians than in American pedestrians and (2) increased responsiveness as a function of condition were supported in a series of log-linear analyses of pedestrian glances, smiles, nods, and greetings. Both of these main effects were, however, qualified by Culture X Condition interactions on smiles, nods, and greetings, with the large condition effects present in the American pedestrians, but absent in the Japanese pedestrians. The results are discussed in terms of the functions of glances, smiles, nods, and greetings in these brief encounters and how differing cultural norms affect Japanese and American responsiveness. Finally, the limitations of this study and the broader utility of this research paradigm are discussed.

Identifying and Distinguishing Value Profiles in American and Israeli Adolescents

Although research has examined how values are correlated with behavior, little has examined how the system of values predicts behavior. In a cross‐cultural sample of American (109 European American; 216 African American) and Israeli (318 Arab Israeli; 216 Jewish Israeli) adolescents, the present study used latent profile analysis to identify groups which reflected the theoretical structure of values across both cultures. Four profiles were found: self‐focused, anxiety‐free, other‐focused, and undifferentiated. Results indicated that Self‐Focused adolescents were the most aggressive and viewed as leaders by their peers compared to the other groups. Self‐Focused and anxiety‐free youth reported more delinquency than their peers. Few differences between cultural groups emerged, suggesting that this approach is a promising avenue for understanding heterogeneity in behavior.     

Chaos and the rationality proposition

Recent research in distributed artificial intelligence may give an analytical model for exchange theory. These researchers have used techniques to control chaotic behavior that correspond to the rationality proposition and may, therefore, give a new avenue of sociological research in exchange theory. This article gives an overview of the research and comments on its potential use in sociology.     

“No strings attached”: A qualitative exploration of gay and bisexual men’s motivations for and attitudes toward engaging in casual sex while on vacation

Prior quantitative research with gay and bisexual men (GBM) has documented high rates of sexual risk behavior during recreational travel. Although some associations are known (e.g., substance use at the tourist destination is associated with sexual risk), less is known about GBM’s motivations for travel and the cognitive and attitudinal factors that influence their sexual behavior while vacationing. In the present study, we conducted qualitative interviews with 46 GBM recruited from three popular gay tourist destinations. Using the Health Belief Model (HBM) as a guiding theoretical framework, the findings of the study revealed that the gay-friendly, tropical, relaxing environments resulted in men letting their guard down and engaging in more risk than when they are at home. Various barriers such as peer pressure and substance use affect GBM’s ability to engage in healthier behaviors while traveling, with condom negotiation and HIV status disclosure as additional issues that impact the sex practices of this population. Results highlight the applicability of HBM constructs to provide insight for intervention development for this population.     

Sources of sex information and premarital sexual behavior∗

Parents and educators have been concerned with the impact of sex education courses and sources of sex information on premarital sexual behavior. This study investigates different sources of sex information, including parents, peers, and others, and how they influence premarital sexual behavior among American college students. This exploratory research is based on the secondary analysis of cross‐sectional data from a national probability sample of 1,177 college students interviewed about their sexual behavior and sexual socialization experiences. Cross‐tabulations between several sources of sex information and a composite index of incidence and prevalence of premarital socio‐sexual involvement are presented. Among females, sexual behavior was influenced in a negative direction by their mothers and in a positive direction by male friends and independent reading. Among males, sexual behavior was influenced in a negative direction by clergymen and in a positive direction by male and female friends and independent reading. Due to the availability of cross‐sectional data only, the need for cautious interpretation is emphasized.     

Migrating for a profession: becoming a Caribbean nurse in post-WWII Britain

Youths from the Global South migrating for further education often face various forms of discrimination. This Caribbean case study discusses how conditions in the home country can provide a foundation for educational migration that helps the migrants overcome such obstacles and even develop a strong sense of agency and self-empowerment. In the post-WWII period, numerous Caribbean women trained in nursing at British hospitals that have been described as marred by race and gender related inequality and associated forms of exploitation. Yet, the nurses interviewed about this training emphasised its high quality and downplayed the problems encountered. This positive attitude, it is argued, must be understood in the light of the key ideological role of education, particularly for a profession, as an avenue of social and personal mobility in the late-colonial Caribbean societies and the ways in which it enabled these Caribbean women to stake out a new life for themselves.     

Adolescent Problem Behavior in China and the United States: A Cross‐National Study of Psychosocial Protective Factors

An explanatory model of adolescent problem behavior (problem drinking, cigarette smoking, and general delinquency) based on protective and risk factors in the individual and in 4 social contexts (family, peer group, school, and neighborhood) is employed in school‐based samples from the People's Republic of China (N=1,739) and the United States (N=1,596). Despite lower prevalence of the problem behaviors in the Chinese sample, especially for girls, a substantial account of problem behavior is provided by the same protective and risk factors in both countries and for both genders. Protection is generally higher in the Chinese sample than in the U.S. sample, but in both samples protection also moderates the impact of risk. Despite mean differences in psychosocial protective and risk factors, as well as in problem behavior, in the 2 samples—differences that may reflect societal variation—the explanatory model has, to a large extent, cross‐national generality.     

A noncooperative marriage model with remarriage

I propose a noncooperative marriage model that explicitly accommodates the possibility of endogenous exit and remarriage, and where marriages are of variable quality. The fundamental innovation is that the remarriage decision is infinitely repeated and the problem is fully stationary, reflecting the contemporary reality in marriage markets. I show that cooperative behavior within marriage is possible in subgame perfect equilibrium both in a setting where marriage quality is independently drawn and in a setting with persistent spouse-specific characteristics and an evolving marriage market quality. I show that spouses engage in cooperative behavior most easily when they have intermediate patience levels, which is a non-standard but intuitive game theoretic result in this setting. This model also contributes to the game theory literature by proposing another avenue for sustained cooperation in a repeated prisoner’s dilemma with endogenous exit: randomness in payoff streams.     

Risky sexual behavior in low‐income African American women: The impact of sexual health variables

In a sample of 163 low‐income African American women, we used logistic regression analyses to test for associations between (a) 5 operationalized constructs theorized in the Sexual Health Model to impact one's overall sexual health (barriers to healthy sexuality, sexual anatomy and functioning, positive sexuality, sexual health care, and cultural identity) and (b) several measures of risky sexual behavior (consistent condom use, multiple concurrent partnerships, and overall sexual risk). No significant relationship was found between acculturation and risky sexual behaviors. Having sexual difficulties was positively associated with overall sexual risk and multiple concurrent partnerships. Favorable attitudes toward condoms were positively associated with consistent condom use. Desiring or intending pregnancy was positively associated with inconsistent condom use and overall sexual risk behavior. This is only the second study linking sexual difficulties and risky sexual behavior. The exact nature of this correlational relationship needs to be studied and replicated in different and more heterogeneous populations.     

Safety First: A Model of Care for Working Systemically With High Risk Young People and Their Families in an Acute CAMHS Service

The following article outlines the Safety First Model for working with high‐risk young people in crisis. This hierarchical model prioritises emotional and physical safety by using multi‐systemic and family‐based interventions. A typical case example is used to illustrate the model and the structures and strategies employed at each level. The intervention model empowers families, facilitates their connections with other providers, and minimises the need for hospital admissions. The model also promotes collaborative and systemic practice in a child and adolescent mental health service.     

Ergonomic analysis of the work conditions of porters and owners of the Supply Center of Campinas, SP

Transforming work conditions is part of the ergonomic action that should help to improve work situations that brings risks to the workers health. six workers were observed in different locations of the supply center (Central Free Market, Free Market 2, Flowers Market and Permanent Shed 4). During the observation of workers to the Ergonomic Analysis of Work - AET (Rohmert and Landau) was performed. The workers were divided into two groups: porters and owners. The porters were the most susceptible to the risks of work and minor accidents with sharp wood from boxes or even risk of traffic accidents as pedestrians. However, regarding the use of mental ability for negotiations, use of computers and organizing and planning the establishment of work, the owners were the ones that most time played these activities. The ergonomics advocates work that can be transformed and that favors employee and employer. It is, therefore, intended to redefine the strategies that are embedded into the organizational structure of work.     

DOES SOCIAL CAPITAL PROMOTE SAFETY ON THE ROADS?

I present evidence that social capital reduces traffic accidents and related death and injury, using data from a 10‐year panel of 48 U.S. states. The econometric challenge is to distinguish the causal effects of social capital from bias resulting from its correlation with unobservable characteristics by state that influence road risks. I accomplish this by employing snow depth as an instrument, and by restricting attention to summertime accidents. My results show that social capital has a statistically significant and sizable negative effect on crashes, traffic fatalities, serious traffic injuries, and pedestrian fatalities that holds up across a range of specifications.

Gender differences in risk behavior and the link to household effects and individual wealth

This study examined the differences in risk behavior between men and women using a household survey that captured the risk preferences of two members in a household and recorded wealth at the individual level instead of the usual approach of representing wealth at the household level. After controlling for commonly used explanatory variables, such as gender, education, age, and wealth, household fixed effects explain about 15% of the variation in risk behavior. This highlights the magnitude of household effects in shaping one’s risk behavior. In general, females in the study area are more risk averse than males based on a risk game with real payout. The gender differences disappear when focusing on only the top land owners. However, even in those cases, females consider themselves more risk averse, supporting results from previous studies that link culture and societal norms to the gender differences in risk behavior.     

The gatekeeper model: implications for social policy

One of the most important needs of an aging population is to insure that older adults are able to live as independently and safely as possible. The question for social policymakers is how to meet this goal in an era of shrinking resources and growing numbers of older adults. The Gatekeeper Model is highlighted as a method to insure that older adults at risk of problems that impact their ability to live independently can be helped by existing systems of care. The model trains employees of community businesses and corporations who work with the public to serve as community gatekeepers by identifying and referring community-dwelling older adults who may be in need of help. A research project was conducted at Spokane Mental Health, Elder Services Division, where the model was developed. The results indicate that community-based gatekeepers found 40% of clients. Gatekeepers find a distinct population of community-dwelling older adults who are not found by more traditional referral sources. The social policy implications of the Gatekeeper Model are discussed.     

Infant‐directed speech to infants at risk for dyslexia: A novel cross‐dyad design

When mothers speak to infants at risk for developmental dyslexia, they do not hyperarticulate vowels in their infant‐directed speech (IDS). Here, we used an innovative cross‐dyad design to investigate whether the absence of vowel hyperarticulation in IDS to at‐risk infants is a product of maternal infant‐directed behavior or of infants’ parent‐directed cues. Interactions between mothers and infants who were at risk or not at risk for dyslexia were recorded in three conditions: when mothers interacted with (a) their own infants, (b) infants who were not their own but of the same risk status, and (c) infants who were not their own and of the opposite risk status. This design revealed both infant and parent effects. Mothers of not‐at‐risk infants hyperarticulated vowels significantly more when speaking to not‐at‐risk than to at‐risk infants. In contrast, mothers of at‐risk infants hyperarticulated vowels significantly less than NAR mothers, and this was irrespective of infant status. Mothers of not‐at‐risk infants thus adjusted their IDS to the infant's risk status, while mothers of at‐risk infants did not. We suggest that IDS is determined reciprocally by characteristics of both partners in the dyad: Both infant and maternal factors are essential for the vowel hyperarticulation component of IDS.     

Effects of facial expression and stare duration on walking speed: Two field experiments

Two field experiments investigated the generality of the stare-escape phenomenon for pedestrians. Experiment 1, conducted at a traffic intersection, failed to replicate a previous finding that being stared at leads to faster walking speed. One hypothesis that could explain this failure is that the relatively short staring times used in Experiment 1 were insufficient for subjects to attribute a threatening meaning to the stare. In Experiment 2, conducted at a library elevator, duration of staring was systematically varied—either 2 seconds or more than 15 seconds. Consistent with the attribution time hypothesis, subjects increased walking speed after a long stare but decreased it after a short stare. In both experiments a smile coupled with a stare appeared to neutralize the effects of a stare alone.The authors would like to thank Clyde Hendrick for his valuable comments on an earlier draft of this paper.     

THE IMPACT OF RESTAURANT CALORIE LABELS ON FOOD CHOICE: RESULTS FROM A FIELD EXPERIMENT

Using field experiment data, we compare the effectiveness of calorie labels to a “fat tax” at reducing calories ordered. Results from a structural model of consumer demand show that numeric labels did not influence food choice, but symbolic traffic light labels caused restaurant patrons to select lower‐calorie menu items; thus, adding a traffic light symbol could enhance the effectiveness of the numeric calorie label (as currently proposed by the Food and Drug Administration). Additionally, our model projects that labels can both reduce intake more than a 10% tax on high‐calorie items and a 10% subsidy on low‐calorie items. (JEL Q18, I18)
