This study examines extant scholarly knowledge on parental acceptance of young lesbian and gay people in traditional heteronormative families. Recent literature shows that parents generally accept their lesbian and gay children. However, parents do not always accept them immediately after they come out. Acceptance takes time, and transitioning to acceptance is often a complex process that depends on parents' access to the necessary resources for coping with the stresses of knowing that their child identifies as lesbian or gay. These resources include counseling or therapy, supportive friends and extended family, and a network of other parents with lesbian and gay children. This study also highlights the need for further research on parental acceptance in nontraditional families and of children with other nonheterosexual identities, such as asexuality, gray ace, bisexuality, or pansexuality. It also calls for an exploration of the complexities of parental acceptance as an ongoing process rather than as a singular event.  相似文献

Comparison of Four New General Classes of Search Designs   总被引:1,自引:0,他引:1  
A factor screening experiment identifies a few important factors from a large list of factors that potentially influence the response. If a list consists of m factors each at three levels, a design is a subset of all possible 3 m runs. This paper considers the problem of finding designs with small numbers of runs, using the search linear model introduced in Srivastava (1975). The paper presents four new general classes of these 'search designs', each with 2 m −1 runs, which permit, at most, two important factors out of m factors to be searched for and identified. The paper compares the designs for 4 ≤ m ≤ 10, using arithmetic and geometric means of the determinants, traces and maximum characteristic roots of particular matrices. Two of the designs are found to be superior in all six criteria studied. The four designs are identical for m = 3 and this design is an optimal design in the class of all search designs under the six criteria. The four designs are also identical for m = 4 under some row and column permutations.  相似文献

The basic assumption underlying the concept of ranked set sampling is that actual measurement of units is expensive, whereas ranking is cheap. This may not be true in reality in certain cases where ranking may be moderately expensive. In such situations, based on total cost considerations, k-tuple ranked set sampling is known to be a viable alternative, where one selects k units (instead of one) from each ranked set. In this article, we consider estimation of the distribution function based on k-tuple ranked set samples when the cost of selecting and ranking units is not ignorable. We investigate estimation both in the balanced and unbalanced data case. Properties of the estimation procedure in the presence of ranking error are also investigated. Results of simulation studies as well as an application to a real data set are presented to illustrate some of the theoretical findings.  相似文献

The paper considers simultaneous estimation of finite population means for several strata. A model-based approach is taken, where the covariates in the super-population model are subject to measurement errors. Empirical Bayes (EB) estimators of the strata means are developed and an asymptotic expression for the MSE of the EB estimators is provided. It is shown that the proposed EB estimators are “first order optimal” in the sense of Robbins [1956. An empirical Bayes approach to statistics. In: Proceedings of the Third Berkeley Symposium on Mathematical Statistics and Probability, vol. 1, University of California Press, Berkeley, pp. 157–164], while the regular EB estimators which ignore the measurement error are not.  相似文献

Initial Public Offerings (IPOs) were the most prevalent form of securities issued to raise capital by firms wanting to go public during the last decade (1990–2000) in the United States. The IPO phenomenon got a tremendous boost during the late 1990s by the popularity of the Internet stocks. In the so-called ‘bubble period’ of 1998–1999, hardly a week went by when one or two IPOs, particularly of the Internet variety, did not appear in the capital market. In this paper we have analyzed the IPO phenomenon during 1990–1995 and during 1996–1999. We have also focused on Internet bubble during 1998–1999, and the IPO meltdown after March 2002. We have found that not all IPOs performed well in 1999, the majority of the 25 IPOs that had the highest first-day gains over 200% in 1999 had also a poor performance record during 2001–2002. As the IPOs issued now are few in number, we may not see the kind of ‘irrational exuberance’ as we witnessed in the late 1990s, for the foreseeable future in the United States.  相似文献

It is arguable that in many-two person bargaining situations disagreement leads to a set of possible payoffs with no probabilities attached to the elements of the set. Axioms are developed for bargaining games of this kind and solution concepts are derived from these axioms. Particular attention is paid to what are here called the max-max and rectangular general solutions. The latter can be applied to an important sub-class of bargaining games where the disagreement set is equal to the feasible set.A part of this work was done while I was a visitor at the University of Stockholm. For valuable discussions and comments I am grateful to T.C.A. Anant, Salvador Barbera, Bhaskar Dutta, Efe Ok, Jorgen Weibull and an anonymous referee of this journal. The paper also benefited from a presentation at the Indian Statistical Institute, New Delhi.  相似文献

South Korea experienced a steep increase in wage inequality between the Asian financial crisis in 1997 and the global financial crisis in 2008. This paper investigates the causes of the sharp change during that time period by looking at the contributions of changes in the distributions of schooling and unionization. The effects are estimated applying two robust distributional function based decomposition methods on Korean Labor and Panel Survey data for the time period 1998–2007. The results suggest changes in the distribution of schooling can explain about 10 % of the changes in the 90/50 percentile wage gap. The declining unionization rate does not have much impact on the upward trend of Korean wage inequality. In addition, aggregate decomposition results suggest that changes in labor force composition can explain a significant proportion of the total wage changes in the upper-tail of the distribution. Based on our findings we provide a list of policy recommendations to address the wage inequality issue in Korea.  相似文献

This article considers the problem of estimating the parameters of Weibull distribution under progressive Type-I interval censoring scheme with beta-binomial removals. Classical as well as the Bayesian procedures for the estimation of unknown model parameters have been developed. The Bayes estimators are obtained under SELF and GELF using MCMC technique. The performance of the estimators, has been discussed in terms of their MSEs. Further, expression for the expected number of total failures has been obtained. A real dataset of the survival times for patients with plasma cell myeloma is used to illustrate the suitability of the proposed methodology.  相似文献

Human Development (HD) requires that development must accompany fundamental human concerns that make life worth living. It is surprising that despite being a democracy, India performs poorly on HD. In this backdrop, four pieces of legislation of different orientations have been passed since 1998–99: ‘Swarnajayanti Gram Swarozgar Yojana’, the ‘Right to Information’, the ‘National Rural Employment Guarantee Act’ and the ‘Right to Education’. Where successful, they have empowered the beneficiaries. Though not expressed as such, nor exclusively directed to this end, these pieces of legislation are bound together with democracy's demand for HD: they are influenced externally by various aspects of globalisation; internally, development is continuously interrogated by democracy, competitive politics and social activism.  相似文献
