Back pack injuries in Indian school children: risk factors and clinical presentations

The use of backpack increased substantially among the school children. Studies have shown that carrying a backpack cause to develop different symptoms of musculoskeletal disorders among the carrier of the backpack. In India there are fewer studies available in literature which explains the musculoskeletal discomfort among the school children. This study aimed at to find out the prevalence of different musculoskeletal problems among the school children. In a retrospective study data were collected for twenty two students. The main diagnostic criteria were pressure mark (redness or swelling) over neck and shoulder corresponding to the straps of the backpack, stooping posture while carrying the back pack, pain or stiffness in the neck, upper back and shoulders predominantly while carrying the back pack and absence of these symptoms during school holidays. Results revealed that pain in the upper back (40%), neck (27%) and shoulder (20%) were most prevalent body regions followed by forearm and wrist pain (7%) and low back (6%). Results further revealed that all the students participated in this study have a pressure mark over shoulder. 54.55% of the children were diagnosed with myofascial pain and rest with thoracic outlet syndrome.     

Mexican American Social Workers’ Perceptions of Doctoral Education and Academia

An increase in Latinos in the social work academy is critical due to current underrepresentation in social work education programs and rapid Latino population growth in the United States. In this qualitative study, perceptions of Mexican American master’s of social work–level practitioners regarding social work doctoral education and academia were explored. Findings indicate a deep commitment to making a contribution to the profession and Latino communities through direct practice, teaching, and field instruction. In addition to structural barriers to pursuing doctoral education, there was skepticism of the relevance of a PhD to serving the profession or Latino communities. Findings are discussed with regard to their implications for recruitment, socialization, and retention of Latino social work students for academic careers.     

Are multinational enterprises from the emerging economies global or regional?

While there is ample statistical evidence that the top 500 multinational enterprises (MNEs) are predominantly home-region-bound or bi-regional, the operations of MNEs from the emerging economies have not been comprehensively analyzed. This constitutes a vital gap since firms from emerging economies have been making prominent acquisitions in recent years, and these economies are expected to post impressive growth despite the global economic slowdown. MNE managers cannot ignore such opportunities and threats. This study analyzes the operations of MNEs from four leading emerging economies – Brazil, Russia, India and China (BRIC). Since aggregated FDI data often lack transparency due to off-shore tax havens, we supplement that analysis by examining 1430 mergers and acquisitions undertaken by MNEs from BRIC economies during 2000–2007. We also develop insights into their dispersion pattern across five industry sectors in six geographical regions.     

Parenting and the process of migration: possibilities within South Asian families

The migration experience creates a unique set of challenges for families, which can result in intergenerational conflict and create the conditions for abuse or neglect. Alternatively, families can cope with these challenges in creative and seemingly contradictory ways, thus strengthening family relationships. This article introduces the process of migration as a theoretical framework to use in understanding the complexity of the migration experience as well as the wide range of coping responses within families. The process was developed as a theoretical tool in an ethnographic study of first- and second-generation South Asian women in the United States; the study's findings are used to illustrate the application of the process to South Asian parenting experiences and show how the process of migration-where families adjust to a different set of structural conditions, ideologies, cultural norms, and social systems-shapes parenting and family life.     

Stochastic Analysis of Complex Repairable System with Deliberate Failure Emphasizing Reboot Delay

Present paper discusses the reliability analysis of a complex system which consists of two repairable subsystems namely A and B connected in series. A is a linear consecutive 2 out of 3:F system and B is a 1 out of n: F system. In this study, two types of failure such as deliberate failure and critical failure have been taken into consideration incorporating reboot delay. Various transition state probabilities, reliability, availability, M.T.T.F., cost analysis, and sensitivity analysis have been obtained along with the steady state behavior of the system. At the end, some special cases of the system have been taken.     

A bivariate mixture of negative binomial distributions and its applications

Abstract

We construct a new bivariate mixture of negative binomial distributions which represents over-dispersed data more efficiently. This is an extension of a univariate mixture of beta and negative binomial distributions. Characteristics of this joint distribution are studied including conditional distributions. Some properties of the correlation coefficient are explored. We demonstrate the applicability of our proposed model by fitting to three real data sets with correlated count data. A comparison is made with some previously used models to show the effectiveness of the new model.     

A test for the mean vector in large dimension and small samples

In this paper, we consider the problem of testing the mean vector in the multivariate setting where the dimension p is greater than the sample size n, namely a large p and small n problem. We propose a new scalar transform invariant test and show the asymptotic null distribution and power of the proposed test under weaker conditions than Srivastava (2009). We also present numerical studies including simulations and a real example of microarray data with comparison to existing tests developed for a large p and small n problem.     

Corporate Reputation: Do Board Characteristics Matter?

Our study draws on institutional and signalling theories to postulate relationships between board characteristics and corporate reputation. Based on a sample of 324 firms featured in Fortune's list of most admired corporations in the USA, our findings indicate that board characteristics significantly influence the assessment of firm reputation by the business community. Specifically, we found that firms with a greater proportion of outside directors and those with larger boards exhibited better reputation than those with smaller boards and a higher proportion of insiders. In addition, we observed an inverted‐U relationship between the average tenure of outside directors and corporate reputation. However, contrary to expectations, our findings indicate a negative association between independent leadership structure (i.e. absence of duality) and corporate reputation.
