The Lasting Effects of Crime: The Relationship of Discovered Methamphetamine Laboratories and Home Values
This study estimates a household’s willingness to pay to avoid the stigma of crime while minimizing concerns of omitted variable bias. By assuming methamphetamine producers locate approximately at random within a narrowly defined neighborhood, this study is able to use hedonic estimation methods to estimate the impact of the discovery of a methamphetamine laboratory on the home values near that location. Specifically, the analysis designates those closest to the site as the treated, while those slightly farther away act as the comparison group. The discovery of a methamphetamine laboratory has a significant effect on the property values of those homes close to the location that peaks from six to 12 months after each lab’s discovery. The estimates found in this study range from a decrease in sale prices of ten to nineteen percent in the year following a laboratory’s discovery compared to the prices for homes that are farther away but still in the same neighborhood. Surprisingly, the impact does not appear to depend on intensity as both the discovery of a second lab and being very close to the discovered lab do not adversely impact home values.Location choice, crime valuation, methamphetamine, housing prices
Love, Toil, and Health Insurance: Why American Husbands Retire When They Do
The provision of health insurance has previously been shown to be an important determinant of retirement timing among older Americans, but the existing literature has largely ignored some aspects of the inter-spousal dependence of health insurance benefits. Specifically, the literature examines only how retirement may affect the health insurance available to the potential retiree but not how it might affect a spouse's options. Using data from the Health and Retirement Study, I find that the impact a husband's retirement might have on a wife's health insurance options has a statistically significant impact on a husband's rate of retirement that is independent of considerations of his own health insurance options. In households where the wife is the only one at risk of losing affordable health insurance if the husband retires, the husband is 30 percent less likely to retire than if neither spouse is at risk (a five percentage point decrease in the retirement rate). Based on these findings, prior research is missing one avenue that changes to the Medicare eligibility age and health insurance policy changes through the Affordable Care Act might impact the labor supply of older workers.Retirement, health insurance, household decision-making
Dye laser traveling wave amplifier
A flashlamp pumped dye laser suitable for use as a single stage amplifier is described. Particular emphasis is placed on the efforts to increase output pulse energy and improve the temporal profile of the injected pulse. By using high power thin film polarizers, output energies reach from 4 to 45 mJ. Various dispersive elements are used to develop an amplified pulse with an extremely clean temporal profile
Dye laser traveling wave amplifier
Injection locking was applied to a cavity-dumped coaxial flashlamp pumped dye laser in an effort to obtain nanosecond duration pulses which have both high energy and narrow-linewidth. In the absence of an injected laser pulse, the cavity-dumped dye laser was capable of generating high energy (approx. 60mJ) nanosecond duration output pulses. These pulses, however, had a fixed center wavelength and were extremely broadband (approx. 6nm FWHM). Experimental investigations were performed to determine if the spectral properties of these outputs could be improved through the use of injection-locking techniques. A parametric study to determine the specific conditions under which the laser could be injection-locked was also carried out. Significant linewidth reduction to 0.0015nm) of the outputs was obtained through injection-locking but only at wavelengths near the peak lasing wavelength of the dye. It was found, however; that by inserting weakly dispersive tuning elements in the laser cavity, these narrow-linewidth outputs could be obtained over a wide (24nm) tuning range. Since the tuning elements had low insertion losses, the tunability of the output was obtained without sacrificing output pulse energy
International Women's Soccer and Gender Inequality: Revisited
A number of authors have identified the determinants of success in international sporting competitions such as the Olympics and soccer’s World Cup. This paper serves to update past work on international women’s soccer performance given the rapid development of the game over the past decade. We compare the determinants of men’s international soccer team performance with that of their female counterparts and find that a different set of variables are important in explaining success for the two genders. While economic and demographic influences hold for both, the impacts of specific political and cultural factors diverge. In particular, Latin heritage predicts men’s success but not women’s, Muslim religious affiliation reduces women’s success but not men’s, and communist political systems tend to improve women’s performance but reduce men’s performance. Several measures of gender equality improve soccer performance for both men’s and women’s soccer suggesting these indicators of gender equality reflect overall levels of development while other measures of equality, particularly those related to women’s access to education, improve women’s soccer performance without enhancing men’s performance.soccer, football, gender inequality, FIFA World Ranking
Harm Reduction Through Effective Volunteer Training
Through a combination of business education and social work competencies, an in-depth analysis of volunteer training was created from existing data and applied to qualitative survey data of nonprofit leaders in the local city of Akron, Ohio. The overall aim of the project was to base volunteer training on evidence, as evidence-based practice is a hallmark of social work practice. In doing so, the training would also aim to build connections among volunteers and between volunteers and the organization to retain the volunteers who were trained and increase the efficiency of the training. Thus, the project sought to reduce two types of harm done in volunteer training: improperly or untrained volunteers and the harm they could do to served populations, and the harm done to an agency with an inefficient training with a high volunteer turnover rate.
The combination of the research led to the creation of a training module based on a local nonprofit, The Well Community Development Corporation’s Akron Hope program. Despite the specificity of the training module, the outline can be applied as a general template for other nonprofits to follow with the addition of their organization and program specific information. As described in the template analysis portion, a balance of standardization and personalization creates an engaging and effective training
