Body Mass Index,Dieting, Romance,and Sexual Activity in Adolescent Girls: Relationships Over Time

Romantic relationships constitute an important, but understudied, developmental context for accommodation to pubertal change. Using a nationally representative sample of 5,487 black, white, and Hispanic adolescent females, this study examined associations among body mass index, current romantic involvement, and dieting. For each one point increase in body mass‐index (BMI), the probability of having a romantic relationship decreased by 6%. Further, involvement in a nonsexual romantic relationship—but not involvement in a sexual romantic relationship—was associated with a significant increase in the likelihood of dieting. Associations between relationship type and dieting did not vary by age, socioeconomic status, or race, but were stronger at higher BMIs. These findings confirm that weight has implications for romantic involvement, which is highly valued by adolescent girls, and that romantic relationships, in turn, are important contexts in which to consider psychological and behavioral accommodation to the physical changes of puberty.     

Exploring the nature of control and its role in the appraisal of workplace stress

The concept of control is a prominent component of theories of stress. From a transactional framework, appraisal of control is seen as important in influencing coping behaviour. However, little attention has been paid to the measurement of the appraisal of control in a work-related situation. In this paper it is argued that situational control should not be reduced to a simple assessment of whether or not an individual has control over a given situation. Instead it is believed that it is important to identify the factors that an individual strives to have control of, as well as the perceived degree of control over those factors. A major component of the present study was the use of a measure that viewed control in this way and that examined control as a multifaceted construct (task control, predictability, self-control and general control). This paper reports on an analysis that examines the multifaceted nature of perceived control with other situational appraisals in the process of coping with workplace stress. A total of 134 employees from four public sector organizations in New Zealand took part in this research. Having control over work tasks was for this sample considered to be less important in giving a sense of control than either predictability or self-control. When it came to reporting how much control they actually had, respondents reported higher levels of self-control than other aspects of control. However, in general respondents reported lower levels of actual control than what they perceived it was important for them to have. This research emphasizes the importance of having a sense of self-control, particularly when it comes to the use of different coping strategies. Overall these findings point to the need to better understand the nature and type of control and its importance if we are to advance our knowledge of work stress.     

Disasters as Learning Experiences or Disasters as Policy Opportunities? Examining Flood Insurance Purchases after Hurricanes

Flood insurance is a critical risk management strategy, contributing to greater resilience of individuals and communities. The occurrence of disasters has been observed to alter risk management choices, including the decision to insure. This has previously been explained by learning and behavioral biases. When it comes to flood insurance, however, federal disaster aid policy could also play a role since recipients of aid are required to maintain insurance. Using a database of flood insurance policies for all states on the Atlantic and Gulf coasts of the United States between 2001 and 2010, this article uses fixed effects models to examine how take‐up rates respond to the occurrence of hurricanes and tropical storms, as well as disaster declarations and aid requirements. Being hit by at least one hurricane in the previous year increases net flood insurance purchases by 7.2%. This effect dies out by three years after the storm. A presidential disaster declaration for floods increases take‐up rates by 6.7%. When disaster aid grants are made available to households, take‐up rates increase by 5%; this accounts for the majority of the increase in policies after occurrence of a hurricane. When the models are estimated taking into account which policies are required by disaster aid, hurricanes are estimated to lead to only a 1.5% increase in voluntary purchases. This overlooked federal policy that disaster aid recipients insure is responsible for a majority of insurance purchases postdisaster.     

Comparison of exercise attitudes and behaviors of urban older adults with AARP's national sample results

This study assessed perceptions about exercise among a convenience sample of low-income, urban, older adult patients at a publicly operated ambulatory primary-care clinic, and results were then compared with the findings of a national study. Although it was expected that the predominantly minority and economically disadvantaged participants in this study would trail significantly behind their White counterparts in their perceptions and behavior regarding exercise, findings demonstrated otherwise. Specifically, when physicians encourage moderate exercise, when patients believe that they can overcome barriers to exercise, and when the environment supports moderate exercise through the availability of community exercise classes, inequities in health behaviors can be reduced. Interventions designed to increase exercise for this population should be developed with an understanding of the many barriers that they will have to overcome, a focus on building confidence, and communicating the many benefits of this behavior.     

Gender comparisons of injection drug use practices in shooting galleries

Previous research studies and anecdotal evidence portray shooting galleries as locales that place injection drug users at great risk for HIV infection, drug use and violence. Collectively, these studies highlight the need to intervene with injectors who frequent shooting galleries. However, few researchers have studied an often-forgotten risk group – women injecting drug users who frequent shooting galleries – and compared their risk behaviors to their male counterparts. To address this gap in the research literature and to evaluate the functionality of the shooting gallery as a setting for HIV prevention, we collected data on risk practices from 201 injectors (101 men and 100 women) who were recruited from eight shooting galleries in Miami, Florida. Results indicate that, compared with men, women injectors engaged in a similar variety and frequency of injection risk behaviors and had more shooting companions. While only minor gender differences were apparent, relatively few injectors – male or female – adhered to current recommendations for needle hygiene practices. Needle hygiene practices existed equally among injectors of both sexes, however very few adhered to current recommendations. Furthermore, contrary to common images of shooting galleries, use of other drugs was infrequently reported, episodes of violence or victimization were uncommon, and sexual contact almost never occurred. Operators of shooting galleries, both men and women, indicated their willingness to participate in HIV prevention efforts. Implications of these findings for HIV intervention indicate that (1) there is a great need to intervene with both men and women IDUs who frequent shooting galleries and that (2) shooting galleries can be an optimal setting for HIV prevention.     

The power of the circular cone test: A noncentral chi-bar-squared distribution

Pincus (1975) derived the null distribution of the likelihood-ratio test statistic for testing that the mean vector of a multivariate normal distribution is zero against the alternative that the mean vector lies in a circular cone. Under the null hypothesis, the likelihood-ratio test statistic has a chi-bar-squared distribution. We extend the results of Pincus by deriving the distribution of the likelihood-ratio test statistic under the alternative hypothesis. In a special case, the distribution is a “noncentral chi-bar-squared” distribution. To our knowledge, this is the first order-restricted testing problem for which the relationship between the null and alternative distributions of the test statistic is similar to the relationship in the linear-model setting. That is, the distribution of the likelihood-ratio test has a central form of a distribution under the null hypothesis and a noncentral form of the same distribution under the alternative.
