Virtual reality based therapy for post operative rehabilitation of children with cerebral palsy

Virtual reality is the use of interactive replication created with computer hardware and software to impart users with opportunities to engage in environments that appear to feel similar to real world objects and events. The commonest rehabilitation program of cerebral palsy children involves stretching, strengthening, mobilization and various other activities, whereas the use of virtual reality based training (VRBT) for rehabilitation of cerebral palsy is not common. To understand the effect of VRBT a study was formulated. Twenty nine subjects participated (study group--14 and control group--15). Outcome measures were MACS, PBS, level of participation, motivation, cooperation and satisfaction of the child. Results revealed that balance and manual ability were significantly improved in both the groups (Balance: study: t-2.28, p<0.05; control: t-3.5, p<0.01; Manual ability: study: t-5.58, p<0.001; control: t-7.06, p<0.001). PBS had significantly greater improvement in the study group (t-t-2.02, p<0.05). Level of participation, motivation, cooperation and satisfaction of the child were also reported to be significantly higher among the study group as compared with control group. To the author's best knowledge, this is the first study on using the VR-based therapy for the postoperative rehabilitation of children with CP which need further elaboration with larger sample size.     

Effects of Firm-specific and Country-specific Advantages on Relative Acquisition Size in Service Sector Cross-Border Acquisitions: An Empirical Examination

Using a sample of 348 service sector cross-border acquisitions by U.S. firms in 44 countries during 1990–2006, our study seeks to identify factors that influence relative acquisition size (acquisition transaction value as a percentage of acquiring firm's asset value). Our findings indicate that firm-specific advantages (FSAs) in the form of available financial slack and target industry knowledge were positively associated with relative acquisition size. However, contrary to expectations, we observed a negative relationship between cross-border acquisition experience and relative acquisition size. In addition, our results suggest that country-specific advantages (CSAs) associated with higher market potential, lower political risk, and greater cultural similarity contributed to increased relative acquisition size in service industry cross-border acquisitions. Finally, our analysis reveals that the relationship between available financial slack and relative acquisition size is contingent on cultural similarity with the relationship being more pronounced when cultural similarity is high.     

Hometown associations and the micropolitics of transnational community development

This article argues that a closer inspection of the historical trajectories and the evolving micropolitics of hometown associations (HTAs) expands our understanding of how community development is practised across borders. Drawing from six years of ethnographic, multi-sited fieldwork carried out in the Dominican Republic and the United States, focusing on the experience of three Dominican HTAs, the evidence presented demonstrates how working dynamics and decision-making responsibilities between internal, international, and non-migrant HTA members shift over time, and identifies the organisational strategies employed to achieve transnational cooperation for community development. The ethnographic data also highlight and explain how communal legacies based on home country agrarian traditions laid the groundwork for future transnational development practices.     

Land use planning: An optimizing model

An optimizing model for comprehensive land use planning (OPTPLAN) is described. Multiple objectives and constraints on desired growth patterns are considered simultaneously in arriving at optimal acreages of ten land use types in several regions within a county or city. Objectives are (i) minimization of conflict between different land uses, (ii) minimization of travel distance of new trips to the existing transportation network, (iii) generation of a fiscally sound plan, and (iv) minimization of environmental impact. Constraints are on each type of land use based on population and employment projections, projected mix of residential dwelling units, local commercial and institutional land needed per thousand persons, location and extent of new industries, open space requirements per thousand population, and natural resource considerations. Application of the model to Du Page County, Illinois is shown.     

Slice sampling for simulation based fitting of spatial data models

An auxiliary variable method based on a slice sampler is shown to provide an attractive simulation-based model fitting strategy for fitting Bayesian models under proper priors. Though broadly applicable, we illustrate in the context of fitting spatial models for geo-referenced or point source data. Spatial modeling within a Bayesian framework offers inferential advantages and the slice sampler provides an algorithm which is essentially off the shelf. Further potential advantages over importance sampling approaches and Metropolis approaches are noted and illustrative examples are supplied.     

Japanese invasion,war preparation,relief, rehabilitation,compensation and ‘state-making’ in an imperial frontier (1939–1955)

ABSTRACT

This paper looks at the history of state-making in an entangled imperial frontier. The northeastern frontier of British India was a mosaic of princely states, administered and un-administered territories. The presence of the colonial state in the region was contentious, marked by violence on one hand and philanthropy on the other. The Japanese invasion of the region during World War Two had several unintended ramifications. Wartime and post-war developments produced institutions and social experiences which facilitated the process of state-making in the region. Relief and Rehabilitation project of the colonial state, and later distribution of monetary compensation was not merely governed by moral or legal obligations but was part of a larger project of imperialist reconquest in Asia after the surrender of the Japanese with Manipur and Naga Hills as the base. This project also provided the postcolonial Indian state with institutions to continue the process of state-making of its own.     

On approximating the distribution of indefinite quadratic forms

This paper provides a simple methodology for approximating the distribution of indefinite quadratic forms in normal random variables. It is shown that the density function of a positive definite quadratic form can be approximated in terms of the product of a gamma density function and a polynomial. An extension which makes use of a generalized gamma density function is also considered. Such representations are based on the moments of a quadratic form, which can be determined from its cumulants by means of a recursive formula. After expressing an indefinite quadratic form as the difference of two positive definite quadratic forms, one can obtain an approximation to its density function by means of the transformation of variable technique. An explicit representation of the resulting density approximant is given in terms of a degenerate hypergeometric function. An easily implementable algorithm is provided. The proposed approximants produce very accurate percentiles over the entire range of the distribution. Several numerical examples illustrate the results. In particular, the methodology is applied to the Durbin–Watson statistic which is expressible as the ratio of two quadratic forms in normal random variables. Quadratic forms being ubiquitous in statistics, the approximating technique introduced herewith has numerous potential applications. Some relevant computational considerations are also discussed.     

国际视野下的儿童权利——介绍国际人类学与民族学联合会儿童、青少年与童年人类学委员会

自从联合国颁布<儿童权利公约以来>,儿童不再被看作是不完整的成年人,而是一个能独立申明自身权利的羽翼丰满的人.儿童权利成为人类学讨论的焦点之一.尽管如此,儿童的参与权、知情权等权利依然受到种种政治、经济和文化障碍的束缚.国际人类学与民族学联合会的"儿童、青少年与童年人类学委员会"是一个相对较新的组织,其目的是共同提出并升华一些指导性的理念,鼓励那些把儿童本身作为主动参与者的研究.该组织希望通过组织会议和出版物传播儿童权利的理念,并推动儿童权利的贯彻.
