Starting to drink: the experiences of Australian lower secondary students with alcohol

This study describes Australian year eight students' (13-14 years old) experiences with alcohol in terms of communication with parents, initiation into drinking, patterns of consumption, context of use, and harms experienced. The sample comprised 521 year eight students from four state government secondary schools in the state of Victoria. Three of the schools are in Melbourne, the capital of Victoria; the fourth is in a rural center. Female and rural students were more likely to talk to parents about alcohol, but this was not associated with safer drinking. Initiation into drinking was higher among rural students. Rural students also drank more, were more likely to drink without adult supervision, to drink to get drunk, and drink more than planned. Student drinkers experienced just over four alcohol-related harms on average in 12 months, with some indication of greater harm among rural students. Higher levels of drinking by rural students, accompanied by more risky patterns of consumption and the possibility of greater harm, supports prioritizing interventions in rural schools.     

A photovoice study of older adults' conceptualizations of risk

Risk is a multifaceted and complex concept that mediates quality of life through the balance between risk taking and risk avoidance. Society expects older adults to identify and manage their personal risks yet little is known about the meaning of risk in their daily lives and how they balance the tensions between taking and avoiding risks. Therefore the purpose of this study was to explore how older adults construe risk. A qualitative exploratory study that incorporated photovoice methodology was used. Seventeen older adults, over a weeklong period, took pictures and kept a log of the places, spaces, events, activities, or situations that best represented risk. Subsequently, they participated in a follow-up individual interview. Older adults viewed risk both positively and negatively, judging the saliency of a risk according to criteria that related both to the risk itself and to personal characteristics. Although risk was avoided in specific situations, risk taking was participants' primary approach to risk, which assumed three forms: adaptive, opportunistic, and/or unjustifiable. Contrary to societal views, older adults view risk as constructive and personally relevant, and as something to be taken and need to be supported in risk taking rather than risk avoidance.     

Variations in Kinship Networks Across Geographic and Social Space

This article analyzes variations in interaction with non‐coresident adult kin based on comparable cross‐national surveys conducted in 2001 in 27 countries. The two main dimensions of kin contact are considered: (1) overall levels and (2) the relative emphasis given to contacts with primary kin (parents, adult children, siblings) and secondary kin (aunts, cousins, in‐laws). Age‐adjusted variations in kin contact between countries are much greater than those within countries. These results do not confirm the commonly hypothesized existence of well‐defined family system boundaries in Europe arising from historical factors. The similarity of patterns of countries outside Europe with European countries with which they have historical ties suggests cultural factors are important in explaining interaction with kin, whereas welfare regimes appear to have little explanatory value. Within Europe, kin contact levels are more strongly related to a north/south divide than to indicators of economic development or religiosity. The findings suggest that neither of the extreme assumptions—homogenizing pressures toward a nuclear family model or persistent well‐defined groupings arising from historical contexts—can be substantiated. Rather, there is a continuum in family behaviors over a substantial range, related to a number of explanatory factors.

Semiautonomous Vehicle Risk Analysis: A Telematics‐Based Anomaly Detection Approach

The transition to semiautonomous driving is set to considerably reduce road accident rates as human error is progressively removed from the driving task. Concurrently, autonomous capabilities will transform the transportation risk landscape and significantly disrupt the insurance industry. Semiautonomous vehicle (SAV) risks will begin to alternate between human error and technological susceptibilities. The evolving risk landscape will force a departure from traditional risk assessment approaches that rely on historical data to quantify insurable risks. This article investigates the risk structure of SAVs and employs a telematics‐based anomaly detection model to assess split risk profiles. An unsupervised multivariate Gaussian (MVG) based anomaly detection method is used to identify abnormal driving patterns based on accelerometer and GPS sensors of manually driven vehicles. Parameters are inferred for vehicles equipped with semiautonomous capabilities and the resulting split risk profile is determined. The MVG approach allows for the quantification of vehicle risks by the relative frequency and severity of observed anomalies and a location‐based risk analysis is performed for a more comprehensive assessment. This approach contributes to the challenge of quantifying SAV risks and the methods employed here can be applied to evolving data sources pertinent to SAVs. Utilizing the vast amounts of sensor‐generated data will enable insurers to proactively reassess the collective performances of both the artificial driving agent and human driver.     

What do urban college students really think about health insurance? A qualitative study

Abstract

Objective: To determine barriers and opportunities to health insurance enrollment among an undergraduate students at a large urban university. Participants: Participants were 31 college students enrolled in 4-year and community colleges in the City University of New York (CUNY), and six health services and insurance enrollment specialists who facilitate and assist in the health insurance enrollment process for CUNY students. Methods: Focus groups were conducted with students and in-depth interviews with key informants in May 2017. Results: The research revealed important insights into how students perceive and value insurance and yielded recommendations for the university to improve enrollment of its students. Conclusions: Many colleges can increase student enrollment in health insurance by informing and educating students about the process. Improving enrollment processes can increase insurance rates and improve student population health.     

The Tragedy of the Atmospheric Commons: Discounting Future Costs and Risks in Pursuit of Immediate Fossil‐Fuel Benefits

One of the most significant positive approaches to the politics of climate change on the scale required by the problem is that of Giddens. This paper uncovers weaknesses in his argument and reveals motivational divergence for mitigation and energy security in both Canada and New Zealand, which is opposite to what occurred in Northern Europe that provided the basis for his analysis. This suggests that the response to climate change varies according to deeper cultural and geophysical structures. The paper also examines cost(risk)‐benefit analysis versus the precautionary principle, the directionality of political‐economic convergence with mitigation, and political partisanship concerning climate change. It documents the complexity of making near‐term economic opportunities converge with mitigation of distant harm.     

Military Occupations: Methodological Approaches and the Military–Academy Research Nexus

Military occupations are continually evolving in relation to the geopolitical changes of societies, their conflicts and conflict management strategies, and technological developments in military hardware and software. Military occupations studies undertaken by the academy have been key to informing government strategy towards the maintenance of functioning armed forces. Since the 1950s, such studies have prioritised ‘top‐down’ quantitative sociological methodologies. This paper reviews these studies and the role of the dominant Institutional/Occupational model. The paper then considers less influential ‘bottom up’ interpretive methodological studies of military occupations. It is suggested that the reliance on ‘top down’ modelling approaches has led to the paucity of studies describing the range and experiential detail of military occupations. The Military–Academy nexus, and the priorities of the discipline of sociology are suggested as reasons for this emphasis.
