Decision Making Clusters in Retirement Savings: Gender Differences Dominate

This study explored the impact of demographic factors on individuals’ investment choice decisions in retirement savings funds. Analysis found identifiable member clusters across a large and diverse sample of almost 150,000 transactions. Results suggested that gender and risk are the most dominant factors with women showing a strong tendency to make lower risk investment choices. If this behavioural tendency is not addressed through education it will accentuate the hurdles women already face in accumulating adequate saving for retirement.     

Conducting research using web-based questionnaires: Practical,methodological, and ethical considerations

The use of the internet for social science research is becoming increasingly common. This paper outlines practical, methodological and ethical issues for researchers to consider when using web-based questionnaires. This is illustrated by consideration of the authors' own experience of conducting a study into the phenomenon of self-harm.     

Unbiased estimation of a nonlinear function a normal mean with application to measurement err oorf models

Let W be a normal random variable with mean μand known variance σ². Conditions on the function f(·) are given under which there exists an unbiased estimator, f(W), of f(μ) for all real μ. In particular it is shown that f(·) must be an entire function over the complex plane. Infinite series solutions for F(·) are obtained which are shown to be valid under growth conditions of the derivatives, f^k( ·), of f(·). Approximate solutions are given for the cases in which no exact solution exists. The theory is applied to nonlinear measurement-error models as a means of finding unbiased score functions when measurement error is normally distributed. Relative efficiencies comparing the proposed method to the use of conditional scores (Stefanski and Carroll, 1987) are given for the Poisson regression model with canonical link.     

A Collaborative Student Affairs and Faculty Health Assessment and Intervention Initiative

Abstract

The authors describe a collaborative partnership forged between faculty and student affairs staff to improve student health at a large urban university. They examine skills and reward structures of each constituency and the stages of the collaboration in the context of 2 theoretical models. A comprehensive data collection and dissemination process in the campus community provided goals for the initial stage of the partnership, leading to implementation of campus initiatives that use the reciprocal skills of each stakeholder. Outcomes of the collaboration included (1) a working relationship between faculty and student affairs staff, (2) increased dialogue with high-level administrators, (3) more coordinated campus efforts to decrease high-risk drinking, (4) use of outcome measures for implementing and evaluating health programs, and (5) an opportunity for interdisciplinary research. The authors offer suggestions for implementing the process on other campuses.     

DEMOCRATIC POLITICS AND THE LONG MARCH ON GLOBAL WARMING: Comments on McCright and Dunlap

The political impasse over global warming legislation stems from obstacles in the mass media arena, public awareness, electoral politics as well as governmental policy. Advocates of global warming policy have to be simultaneously successful in all four major public arenas to prevail. This article provides an overview of the obstacles in each public arena in the United States highlighting the broader context in which McCright and Dunlap's analysis of polarized public opinion operates. Global warming advocates have had their greatest success in the media arena but are checked by the rise of a conservative counter‐campaign as well as media reporting norms, which have contributed to polarized public opinion and limited salience of the issue. Global warming never ranks in the top issue list to which electoral candidates attend, giving it little priority in national electoral contests. Although the House of Representatives passed the Waxman‐Markey Bill in 2009, the bill died in the Senate and will not resurface until the Democratic margin is again large enough to overcome opposition vetoes. At the same time, major legislation has often incubated on the margins of these public arenas for significant time until a political crisis removes the normal obstacles to such major “watershed” legislation. For global warming, the long march through American public arenas appears to have begun.     

Economic infrastructure and the development of state autonomy: A case study of U.S. maritime policy

This paper interprets the development of the U.S. maritime industry as reflecting changes in the economic substructure of American capitalism. The analysis seeks to explain how the changing interests of the state, as well as the changing balance of power between capitalists, workers and the state stimulated changes in the maritime industry. Three time periods are used: the Revolution until 1867; 1868 to 1897; and 1898‐on. These three periods represent distinct periods of policy change and strategies of capital accumulation for the state and for capitalists. A combination of Marxian and Weberian theories of political economy are used to explain these capital‐state relations.     

Election Day Registration's Effect on U.S. Voter Turnout

Objective . Early voter registration deadlines make voting more difficult for many American citizens. In an attempt to facilitate voting, several U.S. states now permit registration on election day, at the height of the campaign. This article examines the turnout effects of adopting election day registration (EDR) and other smaller reductions in closing dates. Methods . Primarily using the Current Population Study (1972-1996), we estimate the turnout advantage of EDR for citizens having low, middle, and high socioeconomic status. Results . The elimination of closing dates, through EDR, is predicted to produce about a 7-percentage-point turnout boost in the average state. Those having a high school education and middle incomes are expected to see the largest turnout gains, with the less educated and poorer citizens doing almost as well. No evidence is found to link the implementation of EDR to subsequent changes in the electorate's partisan balance. Conclusions . Even the most dramatic easing of voter registration costs has a modest effect on the total number of voters and little impact on the long-standing skew toward greater representation of those having higher status in the voting electorate of the United States.     

Prior elicitation in the classification problem

Results are developed concerning the asymptotic behaviour of the Bayes classification rule as the number of unclassified observations grows without bound. It is shown that unclassified observations serve only to estimate the individual population parameters in an unlabeled sense and do not provide information about the labels that are attached to the populations. Prior construction is approached through investigation of prior odds over regions of the joint parameter space (across all populations) deemed likely to contain the true joint parameter vector. It is shown that consideration of these prior odds can lead to more robust a posteriori classification of individual observations.     

Deforestation and the Environmental Kuznets Curve: A Cross-National Investigation of Intervening Mechanisms

Objective . We draw on ecological modernization theory and international political economy arguments to examine the sources of an environmental Kuznets curve (or EKC) that produces an inverted U-shaped rate of deforestation relative to economic development. Method . We use ordinary least squares regression with White's (1978) correction for possible heteroskedasticity to examine the rate of deforestation (1980–1995) in less developed countries. Results . Net of controls for initial forest stock and the quality of deforestation estimates, we find strong evidence for an EKC driven by (1) agglomeration effects linked to the level of urbanization, (2) rural-to-urban migration that partially offsets rural population pressure, (3) the growth of services-dominated urban economies, and (4) strong democratic states. We find little evidence that foreign debt or export dependence influence the deforestation rate. Conclusions . Although deforestation continues to pose pressing and potentially irreversible environmental risks, there is evidence of self-corrective ecological and modernization processes inherent in development that act to mitigate these risks.
