O objetivo deste artigo é identificar e discutir a partir de pesquisa bibliográfica as principais escalas que buscam mensurar as motivações que levam aos espectadores a consumirem esportes. Escalas são ferramentas a disposição do pesquisador social que buscam mensurar determinado fenômeno com o objetivo de verificar de que forma diferentes construtos teóricos podem ser observados na prática social. A partir de pesquisa feita em base de dados identificou-se três escalas principais que mensuram com o construto consumo de esportes: Sport Fan Motivation Scale (SFMS), Fan Attendance Motivation (FAM), Motivation Scale for Sport Consumption (MSSC). A análise destas escalas foi realizada a partir de sete critérios estabelecidos por DeVellis (2012).

Abusive supervision (AS) expresses leadership actions recognized as hostile. This article addresses AS in organizational contexts based on a review of scientific production in the last twenty years. 67 theoretical-empirical studies were analyzed. We found eight specialized journals with publications since 2006, and 185 authors with research conducted in 83 countries. Tepper (2000) was de main reference indicated. Subordinates are the main source of data. The quantitative design was unanimous, presenting different data analysis techniques. Predominant theoretical and analytical models, more evident AS antecedents and consequences in the research are discussed. La supervisión abusiva (SA) expresa acciones de liderazgo reconocida como hostil. Este artículo aborda la SA en contextos organizacionales, partiendo de una revisión de la producción científica en los últimos veinte años. Se analizaron 67 trabajos teórico-empíricos. Encontramos ocho periódicos especializados con publicaciones a partir de 2006, y 185 autores con investigaciones conducidas en 83 países. Tepper (2000) fue la principal referencia indicada. La fuente principal de los datos son los subordinados. La delineación cuantitativa fue unánime, presentando diferentes técnicas de análisis de los datos. Modelos teóricos y analíticos predominantes, antecedentes y consecuencias de SA más evidenciadas en las investigaciones son discutidos.

Objective We report a kindred with a genetic form of REM behaviour disorder (RBD) with autosomal dominant transmission. Patients and methods Clinical, polysomnography study, genetic study and brain MRI were performed to evaluate the index patients. The genetic study included exome sequencing of the index cases that detected 60,869 variants in the individuals examined. Results The kindred has a RBD with autosomal dominant transmission starting in second decade of life. After filtering out the exome variants shared by two affected cases the pool of variants could be reduced to thirteen; one of them is in PVALB, a calcium-binding albumin protein present in gabaergic interneurons in the nervous system that inhibit the pyramidal cell during REM sleep. Conclusions RBD can have a genetic origin. The results of the exome study in this kindred suggest that gabaergic circuits may be altered in patients with RBD. Further studies in this family or in other pedigrees with familial RBD may clear the role of this gene in this disorder.

We have carried an exploratory study by blood transcriptome to find RNA expression signatures in familial ADHD. Samples were collected from three cases with familial ADHD and their paired controls and evaluated by RNA-Seq. Transcriptome profiling identified 7 differentially expressed transcripts with a FDR0.05 that were involved in pathways in Huntington's disease or axonal guidance signaling previously implicated in ADHD, and enriched for signal peptide, growth factor binding, and notably the lipid metabolism pathways. These findings show that blood transcriptome can have an associated signature and highlight a potential to use blood transcriptome to identify patterns of ADHD.
