Shelter Network: serving homeless families and individuals (1987-2007)

Shelter Network is a nonprofit organization that delivers a range of services that meet the needs of homeless families and individuals in order to help them achieve stable housing and self-sufficiency. The agency began as a grassroots community effort to respond to the growing problem of homelessness and its relationship with its external community continues to play an important role in its financing, growth, and development. Over its 20-year history, Shelter Network has overcome multiple challenges related to leadership, finance, and community support and has grown from a grassroots agency into an organization with a budget of $7 million.     

Girls Incorporated of Alameda County at 50: a voice for girls (1958-2008)

Girls Incorporated of Alameda County is nonprofit human service organization that has delivered education, counseling, and advocacy services to girls aged 6 to 18 for 50 years. The organization began as a small, local girls club and has grown into a large multi-faceted service delivery organization attached to a national governing body. The history of Girls Incorporated of Alameda County introduces struggles in relation to external and internal factors that altered the way that the agency financed and managed and exemplifies the important role of nonprofit leadership. The organization's many accomplishments have also presented multiple challenges, particularly related to the changing roles of women in American society.     

The Effect of Immigrant Communities on Foreign‐Born Student Achievement1

This paper explores the effect of the human capital characteristics of co‐ethnic immigrant communities on foreign‐born students’ math achievement. We use data on New York City public school foreign‐born students from 39 countries merged with census data on the characteristics of the immigrant household heads in the city from each nation of origin and estimate regressions of student achievement on co‐ethnic immigrant community characteristics, controlling for student and school attributes. We find that the income and size of the co‐ethnic immigrant community has no effect on immigrant student achievement, while the percent of college graduates may have a small positive effect. In addition, children in highly English proficient immigrant communities test slightly lower than children from less proficient communities. The results suggest that there may be some protective factors associated with immigrant community members’ education levels and use of native languages.     

Trends in educational assortative marriage from 1940 to 2003

This paper reports trends in educational assortative marriage from 1940 to 2003 in the United States. Analyses of census and Current Population Survey data show that educational homogamy decreased from 1940 to 1960 but increased from 1960 to 2003. From 1960 to the early 1970s, increases in educational homogamy were generated by decreasing intermarriage among groups of relatively well-educated persons. College graduates, in particular; were increasingly likely to marry each other rather than those with less education. Beginning in the early 1970s, however; continued increases in the odds of educational homogamy were generated by decreases in intermarriage at both ends of the education distribution. Most striking is the decline in the odds that those with very low levels of education marry up. Intermarriage between college graduates and those with "some college" continued to decline but at a more gradual pace. As intermarriage declined at the extremes of the education distribution, intermarriage among those in the middle portion of the distribution increased. These trends, which are similar for a broad cross section of married couples and for newlyweds, are consistent with a growing social divide between those with very low levels of education and those with more education in the United States.     

Bias-reduced maximum likelihood estimation of the zero-inflated Poisson distribution

Using the techniques developed by Subrahmaniam and Ching’anda (1978), we study the robustness to nonnormality of the linear discriminant functions. It is seen that the LDF procedure is quite robust against the likelihood ratio rule. The latter yields in all cases much smaller overall error rates; however, the disparity between the error rates of the LDF and LR procedures is not large enough to warrant the recommendation to use the more complicated LR procedure.     

Are college students more disturbed today? Stability in the acuity and qualitative character of psychopathology of college counseling center clients: 1992-1993 through 2001-2002

Are clients at college counseling centers more disturbed today than they were 5, 10, or 20 years ago? Since the mid-1980s, counseling center personnel have consistently perceived student clients as more distressed or reported acutely distressed clients as more prevalent than they did 1, 3, or 5 years ago. Only 3 studies employing a systematic, data-based methodology have addressed this question. Two researchers used different actuarial measures of the acuity or character of client pathology and concluded that current student clients are not more disturbed than were earlier ones. One researcher used clinical judgments rendered at the end of therapy and concluded that current students were more distressed. Using the Personality Assessment Inventory, the author found the actuarially determined quantitative and qualitative indices of pathology unchanged for 3,400 counseling center clients seen during 10 consecutive years. Over the same period, the use of medications increased fivefold. An actuarial measure of client distress appears crucial to both accurate diagnosis and treatment and to the adequate preparation of future counseling center professionals.     

Common threads between sample size recalculation and group sequential procedures

Sample size recalculation (SSR) methods ensure that a study closely achieves the required power by allowing for the original sample size to be modified through updating misspecified nuisance parameters. Some SSR procedures extend this concept by incorporating information on the estimated treatment difference as well. While group sequential methodology allows for early stopping of a study in the context of repeated hypothesis tests, SSR usually involves the extension of a study to accommodate misspecified design parameters. This work describes these methods and places them in a common framework. Copyright © 2003 John Wiley & Sons, Ltd.     

Work stressors and cardiovascular disease

Over the past 20 years, an extensive body of research evidence has documented that psychosocial work stressors are risk factors for hypertension and cardiovascular disease. These stressors, which appear to be increasing in prevalence, include job strain (the combination of psychological job demands and low job control), imbalance between job efforts and rewards, threat-avoidant vigilant work, and long work hours. This article reviews the evidence linking these stressors with hypertension and CVD, and the physiological and social psychological mechanisms underlying the associations. Also described are methods for measuring work stressors and new, more accurate techniques for measuring blood pressure. Finally, strategies for reducing work stressors and preventing hypertension and CVD are reviewed. These include clinical assessment, worksite health promotion, work organization interventions, legal approaches and work site surveillance.     

Hippocrates,Maimonides and the doctor's responsibility

Jack Kevorkian criticizes the Hippocratic tradition in Greek medicine, which bans the physician from giving his patient a lethal medication. He sees this prohibition as potentially bringing harm to a suffering patient and not reflective of the larger Greek society which was tolerant and even approving of suicide. However, Kevorkian's advocacy of doctor-assisted suicide can be seen as the polarity of doctor abandonment of the suffering patient rather than as an antidote to it. Both positions involve an outcome of physician removal from the suffering patient, which can be contrasted with Maimonides' command to the physician to watch over the life and death of his patients.
