Authors: Monaco Fabio Chiorino 
Published: August 2018

Um balanço da situação do esporte no Brasil revela sinais preocupantes. O país não investe na formação de novos atletas, na construção e manutenção de estádios, ginásios e centros esportivos, e há grande distância da iniciativa privada. O modelo de gestão característico do setor revela ações voluntárias e descontínuas. O artigo mostra que o futuro do esporte no Brasil depende de ações políticas, sociais, culturais e administrativas capazes de fomentar a profissionalização do setor.

Um economista distante no tempo que tentasse entender o colapso da indústria americana no ano de 2008 ficaria perplexo ao constatar que, nesse mesmo ano, a produtividade das empresas dos EUA seguia de vento em popa. Como então explicar as ondas de enxugamento de pessoal, de fusõesfracassadas, de agressão ao meio ambiente e a derrocada dos sindicatos?Este artigo, escrito ficticiamente no futuro, demonstra como a produtividade observada nesse período era, na verdade, de tipo altamente nocivo.

Testing by Competitors in Enforcement of Product Standards
Authors: Plambeck Erica L. , Taylor Terry A. 
Published: August 2018

Firms have an incentive to test competitors’ products to reveal violations of safety and environmental standards, in order to have competitors’ products blocked from sale. This paper shows that testing by a regulator crowds out testing by competitors, and can reduce firms’ efforts to comply with the product standard. Relying on competitor testing (i.e., having the regulator test only to verify evidence of violations provided by competitors) is most effective in large or concentrated markets in which firms have strong brands and high quality, and for standards that are highly valued by consumers. Under those conditions, firms tend to test competitors’ products and exert high compliance effort. Conversely, unless compliance is highly valued by consumers, a firm with low quality does not draw testing from competitors, and so does not comply. Enforcing a product standard through competitor testing encourages entry by such low-quality, noncompliant firms and can reduce quality investment by incumbents. Stripping offending products of labels (such as “Energy Star”), instead of blocking them from the market, eliminates the problem of entry by low-quality, noncompliant firms, but may reduce incumbents’ compliance efforts.

Residual hip dysplasia: Is there a place for hip shelf operation?
Authors: Terjesen T. 
Published: August 2018

Purpose After modern acetabular osteotomies were introduced, hip shelf operations have become much less commonly used. The aims of this study were to assess the short-term and long-term outcome of a modified Spitzy shelf procedure and to compare the results with those of periacetabular osteotomy (PAO). Methods In all, 44 patients (55 hips) with developmental dysplasia of the hip and residual dysplasia had a modified Spitzy shelf operation. Mean age at surgery was 13.2 years (8 to 22). Indication for surgery was a centre-edge angle < 20° with or without hip pain. Outcome was evaluated using duration of painless period and survival analysis with conversion to total hip arthroplasty (THA) as endpoints. Results Preoperative hip pain was present in 46% of the hips and was more common in patients ≥ 12 years at surgery (p < 0.001). One year postoperatively, 93% of the hips were painless. Analysis of pain in hips with more than ten years follow-up showed a mean postoperative painless period of 20.0 years (0 to 49). In all, 44 hips (80%) had undergone THA at a mean patient age of 50.5 years (37 to 63). Mean survival of the shelf procedure (time from operation to THA) was 39.3 years (21 to 55). Conclusions The Spitzy operation had good short and long-term effects on hip pain and a 30-year survival (no THA) of 72% of the hips. These results compare favourably with those of PAO and indicate that there is still a place for the shelf procedure in older children and young adults.
Proximal femoral growth disturbance in developmental dysplasia of the hip: What do we know?
Authors: Weinstein S. L. , Dolan L. A. 
Published: August 2018

Background Proximal femoral growth disturbance (PFGD) can be the most devastating complication of the treatment of development dysplasia of the hip. The reported incidence ranges from 0% to 73%. The condition involves varying degrees of growth disturbances of the femoral capital epiphysis, the physeal plate or both. Purpose This manuscript will discuss normal growth and development of the hip, the blood supply to the upper end of the femur, pathological and radiographic changes, classifications used to describe PFGD and, most importantly, the potential causes of these growth disturbances and the authors’ strategies for avoiding PFGD.
Closed reduction in late-detected developmental dysplasia of the hip: Indications, results and complications
Authors: Wicart P. , Seringe R. , Glorion C. , Brassac A. , Rampal V. 
Published: August 2018

Purpose The aim of the study was a review of the literature in order to evaluate the results and complications of closed reduction in late-detected developmental dysplasia of the hip (DDH). Methods This study consisted of an analysis of the literature relative to late-detected DDH treatment options considering hip congruency, rates of re-dislocation and of avascular necrosis. Results Gradual closed reduction (Petit-Morel method) appears to be an effective method concerning joint congruency restitution. Dislocation relapse and avascular necrosis are more efficiently prevented with closed versus open reduction. The tendency for spontaneous correction of acetabular dysplasia decreases if closed reduction is performed after 18 months of age. Patient age at the beginning of traction should be considered for the prognosis, with a lower rate of satisfactory results showing after the age of 3 years. Conclusion In our opinion, the Petit-Morel method is a suitable treatment option for children aged between six months and three years with idiopathic DDH.

The objectives of the present study were examined the correlation and regression of body measurements of the Doro Ncanga buffaloes in the Savanna of Mount Tambora Dompu Regency, Indonesia. A total of 339 animals were used in this study. In female, body weight (BW) was found to be significantly (p<0.05) correlated with body length (BL), the degree of correlation increased from 0-6 (r=0.319) to 13-24 months (r=0.394), thereafter decreased at >36 months (r=0.160). The BW was not significantly correlated with height at wither (HW) for all 5 age groups. However, BW and heart girth (HG) were highly correlated (p<0.01) between age groups 0-6 (r=0.967) and >36 months (r=0.978). The BL was significantly (p<0.01) correlated with HW from 0-6 to 13-24 months of age, except for 25-36 months of age. The correlation between BL and HG was highly significant (p<0.01) at 0-6 (r=0.427) and 13-24 (0.371) months of age, then decreased with the increase of age. The HW had no strong correlation with HG at all groups. Regression model of BW changes with HG was predictable with R2 values ranged from 0.896 to 0.957. In male, BW had a strong correlations with HG for age groups 0-6 (r=0.979) and 7-12 months (r=0.972). The BL and HW were not highly correlated with BW at all groups. However, BW was significantly (p<0.01) correlated with HG for age groups 0-6 (r=0.979) and 7-12 months (r=0.972). Their R2 values were 0.958 and 0.945, respectively. A highly significant (p<0.01) correlations were also observed between BL and HW for age groups 0-6 months (r=0.677)and 7-12 months (0.462). The R2 values were 0.458 and 0.214 for the two different age groups, respectively. The estimates of coefficient of determinations and predictive equations show that HG alone could be used to predict BW of female and male Doro Ncanga buffalo at different age groups.

Differentiable Processing of Objects, Associations, and Scenes within the Hippocampus

Published: August 2018

The hippocampus is known to be important for a range of cognitive functions, including episodic memory, spatial navigation, and thinking about the future. However, researchers have found it difficult to agree on the exact nature of this brain structure's contribution to cognition. Some theories emphasize the role of the hippocampus in associative processes. Another theory proposes that scene construction is its primary role. To directly compare these accounts of hippocampal function in human males and females, we devised a novel mental imagery paradigm where different tasks were closely matched for associative processing and mental construction, but either did or did not evoke scene representations, and we combined this with high-resolution functional MRI. The results were striking in showing that different parts of the hippocampus, along with distinct cortical regions, were recruited for scene construction or nonscene-evoking associative processing. The contrasting patterns of neural engagement could not be accounted for by differences in eye movements, mnemonic processing, or the phenomenology of mental imagery. These results inform conceptual debates in the field by showing that the hippocampus does not seem to favor one type of process over another; it is not a story of exclusivity. Rather, there may be different circuits within the hippocampus, each associated with different cortical inputs, which become engaged depending on the nature of the stimuli and the task at hand. Overall, our findings emphasize the importance of considering the hippocampus as a heterogeneous structure, and that a focus on characterizing how specific portions of the hippocampus interact with other brain regions may promote a better understanding of its role in cognition.SIGNIFICANCE STATEMENTThe hippocampus is known to be important for a range of cognitive functions, including episodic memory, spatial navigation, and thinking about the future.

Some properties of approximants for branched continued fractions of the special form with positive and alternating-sign partial numerators
Authors: Antonova T.M. , Dmytryshyn M.V. , Vozna S.M. 
Published: August 2018

The paper deals with research of convergence for one of the generalizations of continued fractions -- branched continued fractions of the special form with two branches. Such branched continued fractions, similarly as the two-dimensional continued fractions and the branched continued fractions with two independent variables are connected with the problem of the correspondence between a formal double power series and a sequence of the rational approximants of a function of two variables.
Unlike continued fractions, approximants of which are constructed unambiguously, there are many ways to construct approximants of branched continued fractions of the general and the special form. The paper examines the ordinary approximants and one of the structures of figured approximants of the studied branched continued fractions, which is connected with the problem of correspondence.
We consider some properties of approximants of such fractions, whose partial numerators are positive and alternating-sign and partial denominators are equal to one. Some necessary and sufficient conditions for figured convergence are established. It is proved that under these conditions from the convergence of the sequence of figured approximants it follows the convergence of the sequence of ordinary approximants to the same limit.
Adolescent Tobacco Smoke Exposure, Respiratory Symptoms, and Emergency Department Use
Authors: Merianos Ashley L. , Jandarov Roman A. , Mahabee-Gittens E. Melinda 
Published: August 2018

OBJECTIVES:
Our objective was to examine the relationship between distinct tobacco smoke exposure (TSE) measures and TSE-related symptoms and emergency department (ED) and/or urgent care (UC) use among nonsmoking adolescents without asthma diagnoses.

METHODS:
We performed a secondary analysis of 7389 adolescents who completed the Population Assessment of Tobacco and Health Study wave 2. Logistic regression and Poisson regression models were built.

RESULTS:
Adolescents with TSE were at increased risk of reporting: shortness of breath, finding it hard to exercise, wheezing during or after exercise, and dry cough at night. Adolescents who lived with a smoker and had home TSE were at increased odds of reporting wheezing or whistling in the chest, and only adolescents with home TSE were at increased risk of reporting wheezing that disturbed sleep. Adolescents with TSE were less likely to report very good or excellent overall health and physical health but were more likely to report they sometimes, often, or very often missed school because of illness. Participants who lived with a smoker and had TSE ≥1 hour were more likely to have had an ED and/or UC visit. Participants with any TSE were at increased risk of having a higher number of ED and/or UC visits.

CONCLUSIONS:
Different TSE measures uniquely increased the risk of TSE-related symptoms, but any TSE increased the risk of having a higher number of ED and/or UC visits. The providers at these high-volume settings should offer interventions to adolescents who are exposed to tobacco smoke and their families to decrease these symptoms and related morbidity.

Published: August 2018

La investigación se realizó en 4 distritos del valle del Mantaro: INIA El Tambo, EEA Mantaro, Chupaca y Huayao; Provincias de Huancayo, Jauja y Chupaca, Departamento de Junín, agosto 2017. Los objetivos fueron: Identificar y seleccionar un número mínimo de propiedades físicas, químicas y biológicas como indicadores de calidad del suelo y contribuir a establecer pautas para mejorar los suelos y sostenerlos. Los indicadores de calidad de suelo se basaron en el concepto de valoración de manejo del suelo (Soil Management Assessment Framework –SMAF) que emplea indicadores múltiples, con el objeto de registrar propiedades físicas, químicas, biológicas y procesos del suelo; cuanto más indicadores se emplee en el análisis, la caracterización será más precisa y es el Conjunto Mínimo de Datos (CMD), esta fue una herramienta que permitió construir un índice que puede ser empleado para evaluar los efectos del manejo a través del tiempo. El análisis de agrupamiento con respeto a las propiedades químicas, reveló diferencias entre localidades y dentro de las mismas. Esto indica que los suelos de Santa Ana (S) y Mantaro (M) no son tan diferentes a los de Huayao (H) y difieren más con respecto a Chupaca (C).El análisis clúster con respecto a las propiedades físicas de los suelos determinó que Huayao y Chupaca forman un grupo similar entre sí pero diferente a los suelos de Mantaro y Santa Ana. Un resultado parecido se observó en el agrupamiento de propiedades químicas.Los resultados de Índices de Calidad (IC) o ICSA, revelaron antes del experimento que Chupaca tiene los mejores suelos y Santa Ana los menos fértiles. Los índices de calidad obtenidos fueron construidos en base a la mejor y peor condición de cada indicador de los suelos experimentales. Sobre la base de los índices de calidad de suelo determinados (Cantú et al., 2007) y luego del análisis de agrupamiento, resulta que los suelos de Chupaca y Huayao tienen similar calidad y son los mejores, le sigue Mantaro y luego Santa Ana, como los de menor calidad. La mejor calidad de suelos se debe a su mayor contenido de materia orgánica y mejor CIC. En base a los cálculos de los índices de calidad del suelo (IC) se ha determinado, para el caso del cultivo de maíz, que los suelos de Mantaro son los mejores y Santa Ana de menor calidad, este caso es similar al análisis inicial. Este resultado corrobora el análisis de componentes principales (ACP). En conclusión, Existe diferente nivel de fertilidad de los suelos en estudio y dentro de las parcelas experimentales antes y después de la aplicación de los tratamientos, mientras que la adición de MO ha acidificado ligeramente el suelo.
