Assam, the northeastern state of India, has experienced strong anti-outsider sentiment for more than half a century now. What makes the Assam case unique is that it has faced both internal as well as illegal international migration in massive scales giving rise to intense existential fear and apprehension among its smaller indigenous communities. Their lack of the required political authority and the indifferent attitude of the Indian Union government in addressing the issue have only multiplied its magnitude. The article explicates the politico-economic dynamics of the immigration issue in Assam and the social tension and conflicts around it in a historical perspective and suggests that a multi-pronged approach backed by strong political will is imperative to negotiate the challenges of immigration in the state in an effective manner. 相似文献

The purpose of this research was to examine a conceptual/theoretical model with negative (substance use) and positive (extracurricular activities) mediating factors between several bonding systems and violent behavior among female youth. Since much of the prior researches have focused on both males and females therefore this study is focusing on females only. Data from the 2011 National Survey on Drug Use and Health was used for this study. For the purpose of this study female research participants between the age of 12–17 were selected (N = 9383). At the stage of bivariate analysis, parental bonding system was omitted from a model before moving onto a structural equation modeling (SEM) analysis as most of the correlations between indicators of parental bonding systems and dependent variables were not significant. Revised model with two bonding systems on violent behavior through two mediating constructs, extracurricular activities and substance use were tested through the SEM and Sobel test analyses. This structural model specifies a satisfactory fit with the sample. Several mediating effects within this model, which help lower the occurrence of violent behavior, were also validated. 相似文献

This article presents the findings of the empirical study of proposed framework of manufacturing excellence (ME) in the Indian industry. The study includes companies from five major sectors, namely automobile, process, machines and equipment, electronics and components and textile. Responses from 90 companies were analysed to explore the validity and reliability of the proposed framework of ME in Indian industry. The developed questionnaire is outlined along with the results obtained from the analysis of the data from the Indian industry. The framework shows high level of reliability and validity. 相似文献

I test if selective out-migration of unhealthy seniors explains why disability rates are so much lower for Florida, as compared
to the national average. This particular area of research is timely given the significant demographic changes relating to
aging. Moreover, this study contributes to the body of literature examining migration with respect to disability and widowhood.
Using State Federal Information Processing Standard (FIPS) and Public Use Microdata Areas (PUMA), I create national maps showing
disability rates for the following age-groups: 50–59, 60–69, and 70+. After creating maps in ARCGIS and conducting univariate
and clustering analysis on mobility disability and personal care limitation, I employ multinomial logit (MNL) analysis to
test if individuals with disability are more likely to out-migrate from Florida. The regression analyses lend support to the
relaxed Litwak and Longino (The Gerontologist, 27(3): 266–272, 1987) second-move hypothesis, which claims individuals with progressively worse health are more likely to undertake another move
to be closer to family and friends. I state “relaxed” because the data does not allow one to determine the reason for migration—only
that migration occurred during the past year. This research informs policy-makers to recognize that elderly in better health
may migrate to places such as Arizona and Florida due to amenity-seeking behavior, but unhealthy elderly are more likely to
leave these states due to assistance-seeking behavior. This out-migration can place excess demand on health services for the
incoming regions, which requires state and local government to ensure resources are in place. Also noteworthy, my results
are less likely to be flawed by erroneous age and sex data in the public use microdata samples (IPUMS) since I stack the 2006
and 2007 American Community Survey (ACS). A recent working studies by Alexander et al. (Inaccurate age and sex data in the
Census PUMS files: Evidence and implications. Munich: CESifo, 2010) shows inaccuracies in the IPUMS for the 1 and 5% 2000 Census, the 2003–2006 ACS, the 2005–2007 3-year ACS, and the 2004–2009
current population survey (CPS) files. 相似文献

School-based substance use surveys are an important data source for prevention and evaluation researchers, but access to students has become progressively restricted by schools. Because almost all states and many districts conduct their own regular surveys, archived data are a potential resource for informed policy and practice decisions. In this study, substance use survey data were successfully collected from 69 of 105 targeted school districts located in 12 states. Results indicate the availability and quality of extant data currently limit their usefulness. Recommendations are made regarding how schools could be assisted to improve the value of their substance use surveys. 相似文献

This article considers the second-order response surface model in which the experimental units, i.e., plots experience the neighbor effects from immediate left and right neighboring plots assuming the plots to be placed adjacent linearly with no gaps. Conditions have been derived for the estimation of coefficients of second-order response surface model. A method of constructing designs for fitting second-order response surface in the presence of neighbor effects has been developed. The designs so obtained are found to be rotatable. 相似文献

Suppose an estimation problem is invariant under a group of transformations and one is interested in finding an optimal equivariant estimator. The usual proactice is to confine attention to non-randomized equivariant estimators based on a minimal sufficient statistic. A justification of this restriction to a smaller clas of estimators is given in this paper under certain conditions. 相似文献

A method of constructing resolvable incomplete block designs for v(=ks, 2 ≤ k ≤ s - 1) treatments in blocks of size k using mutually orthogonal Latin squares is proposed. It has been seen in particular that when the number of replications is s — 1 (or s), which is feasible if s is a prime or a prime power, the method gives PBIB (3) (or semi-regular GD) designs. The analysis of such designs has also been discussed. 相似文献

It is well known that even when the sample observations are correlated and not normal the sample variance, S2 converges in probability to E(S2). But the required sample size for S2 to be a consistent estimator of E(S2) is an open question. Some light is shed on this question in this paper. In particular the relation between the rate of convergence and the correlation property of the observations is explored. It is shown that the retardation to the rate of convergence is not appreciable if the correlation is moderate but it can be severe for extreme correlations. 相似文献
