The idealized cultural identities model on help-seeking and child sexual abuse: a conceptual model for contextualizing perceptions and experiences of South Asian Americans

In this paper, we propose an interdisciplinary framework to study perceptions of child sexual abuse and help-seeking among South Asians living in the United States. We integrate research on social marginality, intersectionality, and cultural psychology to understand how marginalized social experience accentuates South Asian immigrants' desire to construct a positive self-identity. Using model minority ideology as an example of such a construction, we highlight its role in silencing the topic of child sexual abuse within this immigrant community as well as its impact on attitudes towards professional mental health services. We contend that our framework, the idealized cultural identities model on help-seeking and child sexual abuse, provides a unique analytical model for clinicians and researchers to understand how South Asian Americans process, experience, and react to child sexual abuse.     

Dynamics of buried seed population and seedling cohorts of two dominant weeds in a hill agroecosystem of the humid subtropics of India

Dynamics of the buried seeds and plant population of two dominant weeds, viz.,Emilia sonchifolia (Linn.) DC. andRichardsonia pilosa HBK were studied in the crop fields of Meghalaya, north-east India during radish and maize cropping and intervening fallow periods. The total buried seed population ofR. pilosa was always larger than that ofE. sonchifolia, but the germinable fraction was invariably greater in the latter. A major portion (39–41%) of the viable (germinable+dormant) seed population in both weeds was confined to the surface soil layer (0–5 cm). The viable seed population ofE. sonchifolia peaked during April, while that ofR. pilosa showed two peaks (during August and December). The survival pattern and half-lives of seedling cohorts showed, some differences in the two weed species, but both being summer annuals, their populations behaved in a similar manner by showing higher seedling recruitment (K) and survivorship (p) rates in the summer crop (maize) than in the winter crop (radish). However, the density of plants that could attain adulthood was significantly higher inE. sonchifolia thanR. pilosa which might have resulted in greater seed input of the former to the soil leading to its greater abundance in the crop fields.

E-Government and Bureaucracy: Toward a Better Understanding of Intranet Implementation and Its Effect on Red Tape

This article examines the interaction between bureaucratic redtape and intranet usage in state human service agencies. Wepropose a sociotechnical model for the relationship betweenintranet usage and bureaucratic red tape that takes into accountthe complexities of causal linkages including bidirectionalcausal relationships and a range of internal and external influences.This model is tested with data from the National AdministrativeStudies Project, Phase II. While we are not able to corroboratethe "demand pull" hypothesis advanced by Bretschneider and colleagues,we do find support for its corollary (the "technology push"hypothesis) indicating that intranet usage is associated withreduction in red tape. This finding on the salutary effect ofintranet usage holds for both a global measure of red tape anda more specific procurement red tape measure. We conclude witha discussion of the implications of our findings.     

Bayesian shrinkage estimators for a measure of dispersion of an inverse gaussian distribution

The Bayesian shrinkage estimation for a measure of dispersion with known mean is studied for the inverse Gaussian distribution. An optimum choice of the shrinkage factor and the properties of the proposed Bayesian shrinkage estimators are being studied. It is shown that these estimators have smaller risk than the usual estimator of the reciprocal measure of dispersion.     

Postsecondary Education and Economic Well‐Being of Single Mothers and Single Fathers

We investigate the effects of postsecondary education on the economic well‐being of single parents. The data for this study are from the 1993 Panel Study of Income Dynamics, with a sample of 930 single mothers and 168 single fathers. The results indicate that postsecondary education, particularly a 4‐year college degree, improves the economic status of both single mothers and single fathers. Controlling for the effects of education and other factors, single fathers fare better than single mothers, and White single parents fare better than their African American counterparts. To benefit single parents, social policies must devote more resources toward human capital development and reduction of gender‐ and race‐based discrimination in the labor market.     

Modelling on rural out-migration system: a probabilistic approach

"The aim of this paper is to develop a probability model describing the variation in...total out-migration [using] micro-level data. The parameters involved in the models are estimated with the help of [the] method of moment, proportion of zeroth cell and one'th cell respectively, [and] the suitability of [the] model [is] tested through observed demographic survey data [for India]."     

Shared frailty models based on reversed hazard rate for modified inverse Weibull distribution as baseline distribution

The unknown or unobservable risk factors in the survival analysis cause heterogeneity between individuals. Frailty models are used in the survival analysis to account for the unobserved heterogeneity in individual risks to disease and death. To analyze the bivariate data on related survival times, the shared frailty models were suggested. The most common shared frailty model is a model in which frailty act multiplicatively on the hazard function. In this paper, we introduce the shared gamma frailty model and the inverse Gaussian frailty model with the reversed hazard rate. We introduce the Bayesian estimation procedure using Markov chain Monte Carlo (MCMC) technique to estimate the parameters involved in the model. We present a simulation study to compare the true values of the parameters with the estimated values. We also apply the proposed models to the Australian twin data set and a better model is suggested.     

Lead time adjustment through scrap management

In a discrete parts manufacturing environment, it is necessary to compensate for the decreasing planned batch size resulting from production of scrap (defectives) in the production line, by increasing the planned production volume. This calls for a revision in the initially computed manufacturing lead time (MLT). A survey of the literature reveals that although issues related to product quantity regeneration have been studied in detail, little has been done to assess the impact on manufacturing lead times. This paper discusses the impact of scrap on manufacturing lead time in a shop with an intermittent-flow, bath-oriented, discrete-parts manufacturing environment, producing make-to-stock items.     

Estimation of variance of a normal population

In this paper we have suggested two estimators of variance of a normal population developed from the estimators of u² suggested by Govindarajulu and Sahai and Das. These have been shown to be more efficient than the usual estimator s².
