This paper examines the structural change of mutual fund herding in china stock market,an important investment behavior of institutional investors. A self-normalization based Kolmogorov-Smirnov test is employed to test the change point of herding from 2002 to 2011, the results suggest that there really be structural change points in mutual fund herding. The mutual fund herding changed at December 2004, June 2007 and December 2008. The structural change of the mutual fund herding can be explained by the financial environment of China stock market.

Na literatura há escassos estudos da ação da drenagem linfática manual (DLM) na composição urinária. O objetivo deste estudo foi analisar a composição urinária de homens e mulheres usuárias ou não de anticoncepcional oral (ACO) após a DLM. Foram estudados 11 homens (H); 11 mulheres não usuárias de ACO (Mn-ACO) e 12 usuárias (M-ACO), com 21,3 ± 2,9 anos, saudáveis, sedentários e eutróficos. As amostras foram coletadas em um dia, sem intervenção terapêutica, denominado controle, e em outro dia com aplicação da DLM. No total de 4 coletas urinárias, foi analisada a osmolaridade (mOsm/L), a concentração de sódio (mM) e o fluxo (mL/min). Para a análise estatística, utilizou-se o software GraphPad Prism 5.01 e o teste de Kolmogorov-Smirnov para verificar a distribuição da normalidade. Os dados paramétricos foram analisados por ANOVA e ANOVA para medidas repetidas, seguido por Tukey ou Kruskal-Wallis e Friedman, seguido por Dunn’s, para os não paramétricos, com significância p < 0,05. No dia controle, as voluntárias M-ACO apresentaram redução dos eletrólitos e aumento do fluxo urinário. A DLM nos H promoveu redução dos eletrólitos urinários e aumento do fluxo, e em Mn-ACO, aumentou o fluxo. Para M-ACO, a DLM não alterou os efeitos do dia controle. A DLM induz diluição urinária em H e Mn-ACO, entretanto os mecanismos são sexo-dependentes.Palavras-chave: terapia manual, anticoncepcionais, urina.

Objetivo: Analisar os efeitos do Método Pilates na postura corporal estática e no equilíbrio corporal dinâmico de idosas. Métodos: Participaram da amostra 18 mulheres, idade entre 60 e 75 anos, as quais foram submetidas a trinta sessões de Mat Pilates, duas vezes por semana. As avaliações foram realizadas em dois momentos distintos, pré e pós-intervenção. O equilíbrio corporal dinâmico foi avaliado com um teste de equilíbrio validado. A postura corporal estática foi avaliada por fotogrametria, através do software DIPA. A análise estatística foi realizada no software SPSS (v. 18.0), através de estatística descritiva e inferencial. A normalidade dos dados foi verificada através do teste de Kolmogorov Smirnov com correção de Lilliefors, e para comparações do fator tempo foram realizados os testes de Wilcoxon e t de Student. Para todas as análises comparativas foi adotado um nível de significância de 5%. Resultados: Não ocorreram mudanças significativas na postura corporal estática e no equilíbrio corporal dinâmico das idosas, pré e pós-intervenção com o Método Pilates. Conclusão: Trinta sessões de Mat Pilates não produziram mudanças significativas na postura corporal e no equilíbrio dinâmico das idosas estudadas.Palavras-chave: postura, exercício, Método Pilates, saúde do idoso.

AbstractCar manufacturers in Indonesia need to determine reasonable warranty costs that do not burden companies or consumers. Several statistical approaches have been developed to analyze warranty costs. One of them is the Gertsbakh-Kordonsky method which reduces the two-dimensional warranty problem to one dimensional. In this research, we apply the Gertsbakh-Kordonsky method to estimate the warranty cost for car type A in XYZ company. The one-dimensional data will be tested using the Kolmogorov-Smirnov to determine its distribution and the parameter of distribution will be estimated using the maximum likelihood method. There are three approaches to estimate the parameter of the distribution. The difference between these three approaches is in the calculation of mileage for units that do not claim within the warranty period. In the application, we use claim data for the car type A. The data exploration indicates the failure of car type A is mostly due to the age of the vehicle. The Kolmogorov-Smirnov shows that the most appropriate distribution for the claim data is the three-parameter Weibull. Meanwhile, the estimated using the Gertsbakh-Kordonsky method shows that the warranty costs for car type A are around 3.54% from the selling price of this car unit without warranty i.e. around Rp. 4,248,000 per unit.Keywords: warranty costs; the Gertsbakh-Kordonsky method; maximum likelihood estimation; Kolmogorov-Smirnov test.                                   AbstrakPerusahaan produsen mobil di Indonesia perlu menentukan biaya garansi yang bersifat wajar tidak memberatkan perusahaan maupun konsumen. Beberapa pendekatan statistik telah dikembangkan untuk menganalisis biaya garansi. Salah satunya adalah metode Gertsbakh-Kordonsky yang mereduksi masalah garansi dua dimensi menjadi satu dimensi. Pada penelitian ini, metode Gertsbakh-Kordonsky akan digunakan untuk mengestimasi biaya garansi untuk mobil tipe A pada perusahaan XYZ. Data satu dimensi hasil reduksi diuji kecocokan distribusinya menggunakan uji kecocokan Kolmogorov-Smirnov dan taksiran parameter distribusinya menggunakan metode penaksir kemungkinan maksimum. Ada tiga pendekatan yang digunakan untuk menaksir parameter distribusi. Perbedaan dari ketiga pendekatan tersebut terletak pada perhitungan jarak tempuh untuk unit yang tidak melakukan klaim dalam periode garansi. Sebagai bahan aplikasi, kami menggunakan data klaim unit mobil tipe A. Hasil eksplorasi data menunjukkan bahwa kegagalan mobil tipe A lebih banyak disebabkan karena faktor usia kendaraan. Hasil uji kecocokan distribusi untuk data hasil reduksi menunjukkan bahwa distribusi yang cocok adalah distribusi Weibull 3-parameter. Sementara itu, hasil perhitungan taksiran biaya garansi menunjukan bahwa taksiran biaya garansi untuk unit mobil tipe A sekitar 3,54% dari harga jual unit mobil tipe A tanpa garansi, atau sekitar Rp. 4.248.000,- per unit.Kata Kunci: biaya garansi; metode Gertsbakh-Kordonsky; penaksiran kemungkinan maksimum; uji Kolmogorov-Smirnov.
