Effects of a social norm feedback campaign on the drinking norms and behavior of Division I student-athletes

Social norm feedback is a promising strategy for reducing alcohol misuse on college campuses. However, little is known about the impact of these interventions on at-risk populations, such as student-athletes. This study examined the effects of a campus-wide media campaign on Division I student-athletes at three universities. A discriminant function analysis revealed that a composite measure of perceived campus drinking norms distinguished between two campaign exposure groups. With the exception of one perceived norm measure (closest friends), the campaign-exposed group reported more conservative estimates of alcohol use in peers. However, there was no evidence that the campaign had reduced alcohol use. The inability of the campaign to reduce perceptions of alcohol use among one's closest friends may have accounted for the lack of change in drinking behavior. Discussion is directed to the potential limitations of using social norm feedback campaigns to reduce alcohol misuse in high-risk groups, such as student-athletes.     

A Parametric Approach to Flexible Nonlinear Inference

This paper proposes a new framework for determining whether a given relationship is nonlinear, what the nonlinearity looks like, and whether it is adequately described by a particular parametric model. The paper studies a regression or forecasting model of the form y_t=μ( x _t)+ε_t where the functional form of μ(⋅) is unknown. We propose viewing μ(⋅) itself as the outcome of a random process. The paper introduces a new stationary random field m(⋅) that generalizes finite‐differenced Brownian motion to a vector field and whose realizations could represent a broad class of possible forms for μ(⋅). We view the parameters that characterize the relation between a given realization of m(⋅) and the particular value of μ(⋅) for a given sample as population parameters to be estimated by maximum likelihood or Bayesian methods. We show that the resulting inference about the functional relation also yields consistent estimates for a broad class of deterministic functions μ(⋅). The paper further develops a new test of the null hypothesis of linearity based on the Lagrange multiplier principle and small‐sample confidence intervals based on numerical Bayesian methods. An empirical application suggests that properly accounting for the nonlinearity of the inflation‐unemployment trade‐off may explain the previously reported uneven empirical success of the Phillips Curve.     

The Relevance of Self-Determination for Corporate Volunteering Intentions

Corporate volunteering programs are increasingly used to bolster community involvement, address social issues and improve the reputation of organisations. Despite this growing trend, our understanding of what motivates corporate volunteers is scant. Drawing on self-determination theory, this study investigates motivational differences among employees engaging in different corporate volunteering types and in independent volunteering, and examines the relationships between these volunteering types and employees’ intent to volunteer in the future. Findings obtained from a survey of 318 employees suggest that higher levels of motivation to volunteer for reasons of ego enhancement or guilt prevention (introjection) were associated with a higher likelihood of participation in employer-organised, large-scale volunteering. Lastly, compared to the other types of volunteers, corporate volunteers had the highest intentions to volunteer through their company in the future, while independent volunteers had the highest intentions to continue volunteering in their own time without employer support. These results highlight the importance of offering various types of corporate volunteering opportunities to employees, as people engaging in corporate volunteering do not make up a homogeneous group, and that different corporate volunteering activities fulfil different motivational needs.

     

Adult happiness and prior traumatic victimization in and out of the household

A large share of the American population suffers from traumatic experiences early in life. Many adults are also victims of trauma. Using data drawn from the National Comorbidity Survey–Replication, we examine the link between self-reported happiness, a broad gauge of subjective well-being, and four types of traumatic victimization that may occur at various points in the life cycle. In particular, we consider the association between home violence, sexual assault, community violence, and stalking and subsequent victims’ adult happiness. For females and males, we find that each of these traumas significantly reduces self-reported happiness later in the life course, and for both women and men, the estimated impact of home violence is greatest. Furthermore, we find that the adverse effects of trauma on happiness are comparable to the impact of critical socioeconomic developments on happiness. Moreover, we find that experiencing more than one type of these four traumas has a greater negative impact on subsequent happiness than experiencing only one type. Our findings are robust to the inclusion of a wide range of controls, and the influence of trauma on subsequent happiness is independent of personal and family characteristics. Since happiness and mental health are closely related, our work suggests that traumatic victimization undermines overall health and well-being in the U.S.     

Rituals of intimate legal touch: regulating the end-of-game handshake in pandemic culture

This article situates recent attempts to regulate the end-of-game handshake in youth team sports within a broader context of the troubling of touch within pandemic culture. It suggests that the end-of-game handshake is most productively understood as simultaneously: embodied ritual, form of intimate touch, and legal gesture. The analysis invites readers not only to understand the handshake as a complex and meaningful quotidian ritual, but also to see it as an increasingly unstable mode of handwork. The end-of-game handshake, in particular, highlights the clash of values between sport’s imperative to re-establish the normative hetero-masculine haptic order between players at the conclusion of the match, and pandemic culture’s framing of the skin of the palms as dirty and its corresponding requirement, asked of all prudent subjects, that we hygienically manage our everyday haptic contact. In this way, the contested fate of the end-of-game handshake in pandemic culture highlights the multiple ways that touch is understood as a volatile practice demanding regulation.     

Proposed best practice for projects that involve modelling and simulation

Modelling and simulation has been used in many ways when developing new treatments. To be useful and credible, it is generally agreed that modelling and simulation should be undertaken according to some kind of best practice. A number of authors have suggested elements required for best practice in modelling and simulation. Elements that have been suggested include the pre‐specification of goals, assumptions, methods, and outputs. However, a project that involves modelling and simulation could be simple or complex and could be of relatively low or high importance to the project. It has been argued that the level of detail and the strictness of pre‐specification should be allowed to vary, depending on the complexity and importance of the project. This best practice document does not prescribe how to develop a statistical model. Rather, it describes the elements required for the specification of a project and requires that the practitioner justify in the specification the omission of any of the elements and, in addition, justify the level of detail provided about each element. This document is an initiative of the Special Interest Group for modelling and simulation. The Special Interest Group for modelling and simulation is a body open to members of Statisticians in the Pharmaceutical Industry and the European Federation of Statisticians in the Pharmaceutical Industry. Examples of a very detailed specification and a less detailed specification are included as appendices.     

International education in secondary schools explored: a mixed-method examination of one Midwestern state in the USA

In recent years, more and more attention has been paid to international education in schools in the USA. Education professionals, business leaders, and politicians realize that schools and school leaders must identify multiple opportunities for students to interact with and experience a global society. Nationally, there has been a considerable investment of funds by several key foundations and much political talk about the need to push American education towards a model of schooling that expressly responds to the need for internationally competent citizens. Using mixed methodology design, this study is fueled by a desire to better understand several overarching elements in international education. In short, the authors of this paper posit that no further research, policy formation, or program development within the realm of international education for public schools can be undertaken until an understanding of the current state of international education and the capacity for internationalization is empirically explored.     

Mother’s,Household, and Community U.S. Migration Experience and Infant Mortality in Rural and Urban Mexico

This study explores rural and urban differences in the relationship between U.S. migration experience measured at the individual, household, and community levels and individual-level infant mortality outcomes in a national sample of recent births in Mexico. Using 2000 Mexican Census data and multi-level regression models, we find that women’s own U.S. migration experience is associated with lower odds of infant mortality in both rural and urban Mexico, possibly reflecting a process of healthy migrant selectivity. Household migration has mixed blessings for infant health in rural places: remittances are beneficial for infant survival, but recent out-migration is disruptive. Recent community-level migration experience is not significantly associated with infant mortality overall, although in rural places, there is some evidence that higher levels of community migration are associated with lower infant mortality. Household- and community-level migration have no relationship with infant mortality in urban places. Thus, international migration is associated with infant outcomes in Mexico in fairly complex ways, and the relationships are expressed most profoundly in rural areas of Mexico.

REGRESSION ANALYSIS WITH ASYMMETRIC LINEAR LOSS

Asymmetric loss functions often arise where regression estimates are used in management decision making. However, regression analysis has traditionally made use of a symmetric loss function in which the cost of underestimating equals the cost of overestimating. If the loss function is linear and the degree of asymmetry can be determined, the asymmetric regression method presented in this paper can be employed to find appropriate regression estimates. Asymmetric regression analysis requires no unusual data inputs other than an estimate of the cost asymmetry and can be performed efficiently using standard linear programming techniques.
