Maximum likelihood estimation of variance components in a completely random bib design

ABSTRACT

The purposes of this paper are to abstract from a number of articles variance component estimation procedures which can be used for completely random balanced incomplete block designs, to develop an iterated least squares (ITLS) computing algorithm for calculating maximum likelihood estimates, and to compare these procedures by use of simulated experiments. Based on the simulated experiments, the estimated mean square errors of the ITLS estimates are generally less than*those for previously proposed analysis of variance and symmetric sums estimators.     

The Potential of A College Town As A Retirement Community

ABSTRACT

The purpose of this study is to evaluate the potential of college towns as retirement communities. The uniqueness of college towns as potential retirement communities are identified and discussed. Differences between college towns and Sunbelt state retirement destinations regarding the factors that are most concerned by retiree migrants in their decision-making for relocation were compared. The results showed no differences between the college towns and the Sunbelt state retirement cities. Only a few differences existed among the college town subgroups. The findings are of value to the senior living industry, local government and chamber of commerce in their efforts in marketing college towns as prospective retirement communities.     

Rural Perspectives on Same-Sex Marriage

This study explored rural perspectives on same-sex marriage with a nonprobability sample (N = 156) of adult respondents recruited in a largely rural state in the upper Midwest. A new 6-item instrument with strong internal consistency (α =.943) found that support for same-sex marriage was widespread without significant differences based on relationship status, education level, rural residence, or biological sex. Sexual orientation predicted support for traditional family values and same-sex marriage which were inversely associated. Findings suggest that the presumption of rural bias and hostility toward alternative sexualities has mitigated in the upper Midwest. Social work practitioners should infer from this study that there is more to rural culture than remoteness, isolation, poverty, stigma, and conservative religious values. The malleability of rural culture may be an unrecognized strength that may provide encouragement to rural social workers advocating for and serving lesbian, gay, bisexual, and transgender (LGBT) individuals.     

The Role of a Clinical Social Worker in a Changing Society

This paper reviews the anomaly that seems currently to exist within the profession of social work — on the one hand a denigration of the value and utility of individualized services, and on the other, the increased anonymity of life in today's technological society. It is suggested that the need for individualized services will continue to exist regardless of institutional change and that clinical social work will remain an essential and specialized part of the social work profession. It is postulated that if the clinicians look elsewhere for education and recognition this will be a loss for social work.     

An examination of sexual strategies used by urban southern and rural Midwestern university women

The purposes of this study were (a) to determine whether women's use of persuasion, non‐physical coercion, and physical force strategies to obtain sex from a man varied between U.S. women from an urban Southern and rural Midwestern university and (b) to determine if sexual behavior history and early courtship behavior affected the use of these strategies (or not using any strategy). Women from the Midwest and the South did not differ in their use of sexual strategies. There were, however, other variables that accounted for differences in women's use of sexual strategies. Women who used persuasion strategies had fewer lifetime sexual partners than women who used any other strategy. Women who used physical force strategies reported a lower age at first intercourse and more early courtship behaviors than all others. Overall, the results indicated that sexual strategies are related to sexual behavior history and early courtship behaviors rather than cultural setting or demographics.     

Comments

In this paper we compare Bartlett-corrected, bootstrap, and fast double bootstrap tests on maximum likelihood estimates of cointegration parameters. The key result is that both the bootstrap and the Bartlett-corrected tests must be based on the unrestricted estimates of the cointegrating vectors: procedures based on the restricted estimates have almost no power. The small sample size bias of the asymptotic test appears so severe as to advise strongly against its use with the sample sizes commonly available; the fast double bootstrap test minimizes size bias, while the Bartlett-corrected test is somehow more powerful.     

INTERVENTION STRATEGIES: PREDICTING FAMILY THERAPY OUTCOME*

A pre-defined list of family therapy intervention strategies was used to predict post-therapy perceived life happiness and marital happiness among husbands and wives. Clients presented with both child and marriage-focused problems. The data were analyzed separately for husbands and wives. In general, favorable outcome for husbands was associated with active restructuring operations on the part of the therapist. Prediction of outcome for wives was less clear. However, wives did appear to respond favorably to less active interventions such as actualizing transactional patterns and reframing.
