Introduction: Ketamine has emerged as a promising treatment alternative for the management of chronic pain. Despite encouraging findings in civilian populations, and favourable results from trials examining its efficacy in military populations, there is still a dearth of information pointing to optimal specifications related to ketamine administration for pain, depression, and posttraumatic stress disorder (PTSD) in military populations. This meta-analysis and systematic review synthesised available evidence on the effectiveness, tolerability, and feasibility of ketamine in the management of chronic pain and mental health conditions in military populations. Methods: This review followed the Cochrane's Guide for systematic reviews of interventions and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) as frameworks for data collection and synthesis. Results: A total of 11 studies and 22 independent samples were retained for data analyses. Across samples, improvements in pain, depression, and PTSD outcomes were evident, with the use of ketamine leading to significant reductions, g = 1.76, SE = 0.19, 95% CI (1.39, 2.13), Z = 9.26, p <.001. These effect sizes were robust with moderate-to-large effects. In addition, the reductions in symptoms were observed in both active-duty and Veteran groups, and for different routes of ketamine administration, frequencies of ketamine administration, duration of ketamine treatments, dosage, study design, and allowance for concurrent treatments. Discussion: This review provides a preliminary synthesis of available evidence which suggests that ketamine may be a potential option for the treatment of depression, PTSD, and chronic pain in military populations. The viability of ketamine as an alternative treatment may be particularly impactful for those who are treatment resistant, experience chronic symptoms, and/or have exhausted conventional treatments. More research is warranted in order verify the findings presented in this review. [ABSTRACT FROM AUTHOR]

Graphical abstract Abstract We analyse and present the current mainstream research on banking efficiency by assessing recent articles from major finance journals. We examine 87 papers that were published between January 2011 and July 2017. We classify these manuscripts based on study type, approach, objective, and method. We apply clusters and citation networks to identify the evolution of the studies, including research gaps and paradigms. We also analyse the origin of the studies through geographical coordinates to visualize the global connections among the articles. Our study contributes to a future research agenda, studies' integration at international level, and a dissemination of relevant findings on the topic. Moreover, using Lotka's Law, we find that the field of banking efficiency had low productivity, without a significant number of prolific specialized authors or institutions. [ABSTRACT FROM AUTHOR]

We examine the efficiency of Brazilian credit unions through DEA and its relationships with classification groups using Tobit regressions. We applied a traditional analysis model for banks and another approach for cooperatives. We also analyzed the productivity, efficiency and technology changes by applying an Adjacent Malmquist. The main results indicate that the link between cooperative members is not determinant for efficiency; nevertheless, free admission cooperatives tend to be less efficient than those that have admission restrictions. It is also noteworthy that the contrasting results generated by the models point to the need for specific models that consider outputs relevant to cooperatives. RESUMEN Examinamos la eficiencia de las cooperativas de crédito brasileñas a través del análisis envolvente de datos (DEA - Data Evolopment Analysis) y sus relaciones con los grupos de clasificación, usando las regresiones Tobit. Aplicamos el modelo analítico tradicional y otro enfoque para las cooperativas. También analizamos la productividad, eficiencia y cambios tecnológicos, en base al índice Adyacente de Malquist. Los resultados más importantes indican que la eficiencia no es un factor determinante del vínculo existente entre los miembros de las cooperativas. Sin embargo, las cooperativas con admisión libre, suelen ser menos eficientes que aquellas que imponen restricciones a su admisión. También es de interés mencionar que los resultados contrastantes generados por los modelos señalan la necesidad de contar con modelos específicos que tomen en cuenta resultados importantes para las cooperativas. RESUMO O presente trabalho estudou a eficiência das cooperativas de crédito brasileiras, através da DEA e suas relações com grupos de classificação, usando as regressões Tobit. Foi empregado um modelo de análise tradicional para os bancos e outra abordagem para as cooperativas. Também foram analisadas a produtividade, a eficiência e as mudanças tecnológicas, com o uso do índice Adjacent Malmquist. Os principais resultados indicam que a vinculação entre os membros cooperados não é um fator determinante para a eficiência; no entanto, as cooperativas com admissão livre tendem a ser menos eficientes do que aquelas com restrições à admissão. Também cabe ressaltar que os resultados divergentes, gerados pelos modelos, indicam a necessidade de modelos específicos que estudem resultados relevantes para as cooperativas.

This article evaluates if brazilian publicly traded companies that have higher corporate governance levels, according to brazilian stock exchange (BM&FBOVESPA) segments, have more pulverized property structures, as diffused by corporate governance principles, or if the adhesion to the segments can occur only due to the isomorphism process described by the New Institutional Sociology. For that, this study used, after the elimination of atypical observations, and using the data from 343 companies, in wich 122 are owned by Novo Mercado (NM) list, 17 to Nivel 2 (N2), 37 to Nivel 1 (N1) and 167 that were not owned by any governance special segment (Grupo Tradicional - GT). To statistic operationalization, there were used hypothesis tests (t test and ANOVA) to verify if there were substantial differences between the ownership dispersion averages of especial corporate governance and the traditional segments averages from BM&FBOVESPA. The percentual of stocks belonged to stockholders with less than 5% of stocks from each species were used as proxy of dispersion degree. The test t results revealed the existence of significant differences between the dispersion averages from the enterprises group belonged to the special segment and the GT averages, translating the expectations existents in literature about the possibility of corporate governance mechanisms propitiate higher ownership dispersion. Through Variance Analysis (ANOVA), it was also identified significant differences between the four segments (NM, N2, N1 and GT), however, differently than expected, it wasn't verified a linear stock dispersion increase according to the governance level increase of BM&FBOVESPA.
