Sexual Minority Stress and Same‐Sex Relationship Well‐being: A Meta‐analysis of Research Prior to the U.S. Nationwide Legalization of Same‐Sex Marriage

Meta‐analytic methods were used to analyze 179 effect sizes retrieved from 32 research reports on the implications that sexual minority stress may have for same‐sex relationship well‐being. Sexual minority stress (aggregated across different types of stress) is moderately and negatively associated with same‐sex relationship well‐being (aggregated across different dimensions of relationship well‐being). Internalized homophobia is significantly and negatively associated with same‐sex relationship well‐being, whereas heterosexist discrimination and sexual orientation visibility management are not. Moreover, the effect size for internalized homophobia is significantly larger than those for heterosexist discrimination and sexual orientation visibility management. Sexual minority stress is significantly and negatively associated with same‐sex relationship quality but not associated with closeness or stability. Sexual minority stress is significantly and negatively associated with relationship well‐being among same‐sex female couples but not among same‐sex male couples. The current status of research approaches in this field is also summarized and discussed.     

Measures of Social Isolation

Social isolation is a deprivation of social connectedness. It is a crucial aspect that continues to be named by people as a core impediment for achieving well-being and as a relevant factor for understanding poverty. However it is not routinely included in surveys that provide data on multidimensional poverty measurement. Although the challenge of measuring social connectedness is daunting, this paper argues that existing research in several fields provides solid ground for the construction of basic internationally comparable indicators that measure specific aspects of social isolation. In particular, this paper synthesises the relevant literature on the measurement of social isolation and related phenomena, and on the basis of this synthetic review, proposes a module of indicators to measure social connectedness that could be feasibly incorporated into an internationally comparable multi-topic household survey.     

Sensitivity of Concentration and Risk Predictions in the PRESTO and MMSOILS Multimedia Models: Regression Technique Assessment

This paper describes the application of two multimedia models, PRESTO and MMSOILS, to predict contaminant migration from a landfill that contains an organic chemical (methylene chloride) and a radionuclide (uranium-238). Exposure point concentrations and human health risks are predicted, and distributions of those predictions are generated using Monte Carlo techniques. Analysis of exposure point concentrations shows that predictions of uranium-238 in groundwater differ by more than one order of magnitude between models. These differences occur mainly because PRESTO simulates uranium-238 transport through the groundwater using a one-dimensional algorithm and vertically mixes the plume over an effective mixing depth, whereas MMSOILS uses a three-dimensional algorithm and simulates a plume that resides near the surface of the aquifer.A sensitivity analysis, using stepwise multiple linear regression, is performed to evaluate which of the random variables are most important in producing the predicted distributions of exposure point concentrations and health risks. The sensitivity analysis shows that the predicted distributions can be accurately reproduced using a small subset of the random variables. Simple regression techniques are applied, for comparison, to the same scenarios, and results are similar. The practical implication of this analysis is the ability to distinguish between important versus unimportant random variables in terms of their sensitivity to selected endpoints.     

Recent minimum wage increases and the minimum wage labor force

Coclusion  Recently Whaples (1996) reported that most labor economists believe that minimum wage laws decrease employment. Despite this, policy makers have continued to periodically raise the minimum, with the most recent increases occurring in October 1996 and September 1997. The various analyses done by Card, Katz, and Krueger, that showed little to no employment effect of past minimum wage increases, have provided additional ammunition for those who would seek further increases. However, using the estimates of Williams and Mills (1998), we demonstrate that the latest minimum wage increases substantially decreased employment for both sexes. We believe that future increases will do likewise.     

A COMPUTER LANGUAGE FOR MATHEMATICAL PROGRAM FORMULATION

Using a Conversational Modelling Language (CML), a special computer language has been implemented to allow the specification of mathematical programming models and their parameterization. The language has been designed to be “natural” in the mathematical programming context and to include interfaces with computer routines, such as MPSX, for optimization. Features implemented include equation writing, preparation of computer input, automatic checking and removal of redundancies, and the ability to display solutions given sufficient specification of decision variables. Examples of the use of the language in building interactive decision support systems are given.     

POLICY CHANGES IN MAJOR LEAGUE BASEBALL: IMPROVED AGENT BEHAVIOR AND ANCILLARY PRODUCTIVITY OUTCOMES

Offense in Major League Baseball (MLB) has decreased substantially since 2006, often attributed to increased testing and punitive action for use of performance enhancing drugs. However, there has been concurrent policy change affecting behavior of other league agents that may have also affected game play. I therefore examine the effect of these agents, MLB umpires, on offensive production in baseball. Estimates reveal that a substantial portion of the offensive reduction from 2008 through 2014 can be attributed to changes in the size of the strike zone. Implications are further discussed in the context of firm production relevant outcomes as they relate to the labor force and supervisor performance expectations. (JEL J44, Z22, Z28, L25)     

Invisible disabilities,visible Service Dogs: the discrimination of Service Dog handlers

This article examines the social experiences of Service Dog handlers using survey data from adult US Service Dog handlers (N = 482). The main research question examined is how disability visibility impacts the experiences of Service Dog-related discrimination. Analysis reveals that half of all Service Dog handlers report experiencing discrimination but those with invisible disabilities report experiencing significantly more discrimination. For those with invisible disabilities, the decision to use a Service Dog prevents them from ‘passing’ while at the same time opening them up to increased skepticism about the legitimacy of their disability.     

An Overview of a Multimedia Benchmarking Analysis for Three Risk Assessment Models: RESRAD, MMSOILS, and MEPAS

Multimedia modelers from the United States Environmental Protection Agency (EPA) and the United States Department of Energy (DOE) collaborated to conduct a detailed and quantitative benchmarking analysis of three multimedia models. The three models—RESRAD (DOE), MMSOILS (EPA), and MEPAS (DOE)—represent analytically-based tools that are used by the respective agencies for performing human exposure and health risk assessments. The study is performed by individuals who participate directly in the ongoing design, development, and application of the models. Model form and function are compared by applying the models to a series of hypothetical problems, first isolating individual modules (e.g., atmospheric, surface water, groundwater) and then simulating multimedia-based risk resulting from contaminant release from a single source to multiple environmental media. Study results show that the models differ with respect to environmental processes included (i.e., model features) and the mathematical formulation and assumptions related to the implementation of solutions. Depending on the application, numerical estimates resulting from the models may vary over several orders-of-magnitude. On the other hand, two or more differences may offset each other such that model predictions are virtually equal. The conclusion from these results is that multimedia models are complex due to the integration of the many components of a risk assessment and this complexity must be fully appreciated during each step of the modeling process (i.e., model selection, problem conceptualization, model application, and interpretation of results).     

A New Empirically Weighted Monetary Aggregate for the United States

This article uses an approach to long-run modeling proposed by Pesaran, Shin, and Smith (2001) to develop an empirically weighted broad monetary aggregate for the United States and to demonstrate the advantages of this type of aggregate from a monetary policy perspective. The new empirically weighted aggregate performs well in out-of-sample nominal income and inflation forecasting tests, and in respect of the latter is clearly superior to simple sum M2, Divisia M2, and simple sum M2+ (which includes stock and bond mutual funds) over the period 1991–2001.
