Oral health among student veterans: Effects on mental and physical health

Abstract

Objective: The purpose of this study was to explore differences in oral health among students by military service status in postsecondary settings. Participants: Secondary data were obtained from the American College Health Association’s 2011–2014 National College Health Assessment II. Method: Demographic characteristics of the study sample were explored by calculating frequencies and percentages by military service status. Research questions were explored with maximum likelihood multiple logistic regression. Results: Service member and veteran students are at greater risk for neglecting health behaviors associated with positive oral health, including that they were less likely to get dental exams and that those who deployed in the past were the least likely to be practicing good oral health. Conclusions: The results suggest that improving oral health will contribute to improving health and mental health outcomes in this population, and provide important information for health specialists working with service members and veterans on college campuses.     

Treatment Choice With Trial Data: Statistical Decision Theory Should Supplant Hypothesis Testing

Abstract

A central objective of empirical research on treatment response is to inform treatment choice. Unfortunately, researchers commonly use concepts of statistical inference whose foundations are distant from the problem of treatment choice. It has been particularly common to use hypothesis tests to compare treatments. Wald’s development of statistical decision theory provides a coherent frequentist framework for use of sample data on treatment response to make treatment decisions. A body of recent research applies statistical decision theory to characterize uniformly satisfactory treatment choices, in the sense of maximum loss relative to optimal decisions (also known as maximum regret). This article describes the basic ideas and findings, which provide an appealing practical alternative to use of hypothesis tests. For simplicity, the article focuses on medical treatment with evidence from classical randomized clinical trials. The ideas apply generally, encompassing use of observational data and treatment choice in nonmedical contexts.     

An Audit of Literature Reviews Published in Australian Social Work (2007–2017)

ABSTRACT

This study examined the nature of literature reviews published in Australian Social Work between 2007 and 2017. An audit was conducted to determine the number of reviews; types of reviews (systematic, meta-analysis, metasynthesis, scoping, narrative, conceptual, critical); and elements that were commonly reported (based on items drawn from the PRISMA checklist) including quality appraisal. A total of 21 reviews were identified. Results showed the overall number of reviews published remained relatively consistent across the decade. In relation to review types, systematic and scoping reviews appeared with greater frequency in more recent years. Most reviews reported significant proportions of the elements consistent with the type of review undertaken, although a minority did not report the search strategies and only one review included a quality appraisal. In conclusion, the reviews published over the last decade provide a strong foundation upon which further advances in the diversity and quality of reviews can be built.

IMPLICATIONS

• Literature reviews are an indispensable tool for accessing knowledge to inform social work practice.

• This first audit of literature reviews in Australian Social Work found a growing sophistication in the reviews published over the past decade.

• Continued improvements in the design, conduct, and reporting of literature reviews will be an invaluable resource in equipping the profession to respond successfully to the growing complexity of demands placed on social work practice in the 21st century.

     

Network Neutrality Versus Paid Prioritization: Analyzing the Impact on Content Innovation

We examine the link between network neutrality (NN) and content innovation on the Internet by comparing the impact of NN and packet discrimination (PD) regimes on content innovation. We do this in the context of a two‐sided market model that simultaneously considers content provider (CP) and consumer decisions concerning market entry and participation while taking into account consumers’ response to network congestion. We find that content innovation flourishes under NN to a greater degree than under PD due to two effects we uncover: the generation of what we call a pro bono innovation zone in which CPs are able to enter the market without contributing to network provider profits; and the cross‐side congestion effect, a negative network externality wherein higher broadband market coverage levels result in greater congestion for CPs, and increased content results in greater congestion for consumers, taking into account consumers’ strategic response to network congestion. These results have important implications for current public policy debates regarding the Federal Communications Commission's Open Internet Rules.     

Research as a Social Process

The activity of social research has been much discussed in recent years. It is examined here as a social process, with special attention to the participation of different groups of people. Four modes of doing research are identified. The framework accommodates and shows close relationships between established modes of research which generally have been seen to be substantially different. At the same time it includes modes which are more participatory in character and which have important implications for undertaking research, the development of theory, and the functioning of social groups, including society.     

Agency Decentralization: Planning and Assessment

Summary Criteria are examined for the location of area offices in SocialServices Departments, drawing on the monitored experience ofdealing with voluntary callers to an area office in the ProbationService. Changes were observed in numbers of voluntary callersand the kinds of problems presented, together with developmentsin inter-agency relationships. The caller's subjective feelingsregarding the accessibility of the agency were found to be importantdeterminants of agency use. Implications are drawn out for planningdecisions in local authorities     

Solution Procedures for the Lot-Streaming Problem

Lot streaming is the process of splitting a job into sublots so its operations can be overlapped and its progress accelerated. We present a computationally efficient procedure for solving the m-machine, two-sublot problem, and we discuss the bottleneck insights that emerge from the analysis. We also examine heuristic approaches for more than two sublots and discuss computational results for these procedures.
