    Regulating Bodies: Children and Sexual Violence

    The interdisciplinary silences on sexual violence and the omission of children and youth from social science research speak volumes of the power of the child as a flexible, cultural signifier. In this article, I argue that dominant frameworks of children and childhood make child sexual assault a discursive impossibility for most young people. The epistemic violence of silencing matters, and it is these erasures that are fundamental to understanding violence and power. I argue it is paramount for feminist researchers to call attention to the undermining qualities of Institutional Review Boards that act as gatekeepers of representation and voice

    CD -24_17504 revisited: a new comprehensive element abundance analysis

    Get PDF
    With [Fe/H] ~ -3.3, CD -24_17504 is a canonical metal-poor main sequence turn-off star. Though it has appeared in numerous literature studies, the most comprehensive abundance analysis for the star based on high resolution, high signal-to-noise spectra is nearly 15 years old. We present a new detailed abundance analysis for 21 elements based on combined archival Keck-HIRES and VLT-UVES spectra of the star that is higher in both spectral resolution and signal-to-noise than previous data. Our results for many elements are very similar to those of an earlier comprehensive study of the star, but we present for the first time a carbon abundance from the CH G-band feature as well as improved upper limits for neutron-capture species such as Y, Ba and Eu. In particular, we find that CD -24_17504 has [Fe/H] = -3.41, [C/Fe] = +1.10, [Sr/H] = -4.68 and [Ba/H] <= -4.46, making it a carbon enhanced metal-poor star with neutron-capture element abundances among the lowest measured in Milky Way halo stars.Comment: Accepted to ApJ. 24 pages, 13 figures, 7 table

    The Effect of Food Deserts on the Body Mass Index of Elementary School Children

    Families in low-income neighborhoods sometimes lack access to supermarkets that provide a broad range of healthy foods. We investigate whether these so called "food deserts" play a role in childhood obesity using a statewide panel data set of Arkansas elementary schoolchildren. We use fixed-effects panel data regression models to estimate the average food desert effect. We next compare children who left (entered) food deserts to children who were always (never) in food deserts and homogenize samples for those whose food desert status changed as a result of a change in residence and those whose status changed only as a consequence of the entry or exit of a supermarket. We present evidence that exposure to food deserts is associated with higher z-scores for body mass index. On average, this is in the neighborhood of 0.04 standard deviations. The strongest evidence and largest association is among urban students and especially those that transition into food deserts from non-deserts. Our food desert estimates are similar in magnitude to findings reported in earlier work on diet and lifestyle interventions targeting similarly aged schoolchildren. That said, we are unable to conclude that the estimated food desert effect is causal because many of the transitions into or out of food deserts result from a change in residence, an event that is endogenous to the child's household. However, there is evidence that food deserts are a risk indicator and that food desert areas may be obesogenic in ways that other low-income neighborhoods are not

    Gendered Violence and the Ethics of Social Science Research

    The issue of ethical conduct in research settings is important and complex. As tenure-track researchers who study gendered violence, we found Clark and Walker’s discussion provocative, thoughtful, and interesting. They urge researchers to attend both to the structural dynamics of research carried out under the pressures of tenure and promotion while advocating an ethical frame that draws attention to the limited definition of risk or harm that animates typical human subjects research. Victims of violence, they argue, should not be subjected to a standardized understanding of risk. A broader framework is needed, one that brings into conversation virtue ethics with consequentialist and ontological frameworks. Given the impossible task of responding to the many points discussed by Clark and Walker, we chose to focus on four areas. In all likelihood, these areas of discussion reflect our own interests rather than Clark and Walker’s, but challenged to think seriously about research ethics in victimization studies, we attend to the following points. First, we seek to put virtue ethics in conversation with care ethics, in part because care ethics formed an important component of feminist discourse during the historical period in which institutional review boards came into being. Although virtue ethics may have lost its masculinist inflection after shedding its etymological roots,1 care ethics was explicitly seen as suited for the feminist subject. Following our discussion of care ethics, we address the question of setting victims of violence apart as a special class of vulnerable human research subjects. We argue that such a designation may yield more problems than it does solutions. Next, we turn to the violence of epistemology as a concern in research ethics. How do we come to an ethical definition of the research object, and to whom are we accountable? Finally, we turn to the relation of care when carrying out ethically and methodologically sound research

    AN ECONOMIC ANALYSIS OF PRODUCTIVE EFFICIENCY IN ALBERTA DAIRY PRODUCTION

    Get PDF
    The World Trade Organization is currently formulating an agenda for a new round of global trade negotiations. Therefore, the likelihood of increased competition within Canada's supply managed dairy industry is probable. Consequently, there is agreater need for producers to be concerned with efficiency and with their competitiveness in the international marketplace. This study assessed the cost efficiency and competitiveness of Alberta dairy producers by estimating the economic costs associated with milk production, and deriving the physical and economic efficiency of producers. Results support the presence of economies of size and economies of yield within Alberta milk production. A link between increased herd size, labour productivity, and lower total labour costs was identified in the analysis.Productivity Analysis,

    Developing Attorneys for the Future: What Can We Learn From the Fast Trackers?

    Get PDF
    Leaders in law firms tend to be those attorneys who thrive in a law firm environment from the beginning—successful associates who become successful partners. Later, they are asked to be the leaders of practice areas, committees and, ultimately, part of senior management. While high-performing associates may not be formally promoted to leadership positions for some time, it is important to understand what makes them—as young associates—stand out from their peers. Who are these future leaders, and what qualities predict their advancement in a law firm environment? These are the questions we set out to explore. To date, little empirical work exists on the characteristics and behaviors of high-potential associates—how to recognize them from the beginning and how to develop them. Instead, law students continue to be hired most commonly based on the law school they attended and their GPA, under the assumption that law school and GPA are related to future performance as an attorney. Transcript and resume review are typically accompanied by a series of 30-minute interviews consisting of questions that vary from candidate to candidate. Consequently, hiring decisions result from a combination of the reputation of the law school attended, GPA, and the interviewing partners’ gut feeling

    Real Time Changes in Monetary Policy

    This paper investigates potential changes in monetary policy over the last decades using a nonparametric vector autoregression model. In the proposed model, the conditional mean and variance are time-dependent and estimated using a nonparametric local linear method, which allows for different forms of nonlinearity, conditional heteroskedasticity, and non-normality. Our results suggest that there have been gradual and abrupt changes in the variances of shocks, in the monetary transmission mechanism, and in the Fed’s reaction function. The response of output was strongest during Volcker’s disinflationary period and has since been slowly decreasing over time. There have been some abrupt changes in the response of inflation, especially in the early 1980s, but we can not conclude that it is weaker now than in previous periods. Finally, we find significant evidence that policy was passive during some parts of Burn’s period, and active during Volcker’s disinflationary period and Greenspan’s period. However, we find that the uncovered behavior of the parameters is more complex than general conclusions suggest, since they display considerable nonlinearities over time. A particular appeal of the recursive estimation of the proposed VAR-ARCH is the detection of discrete local deviations as well as more gradual ones, without smoothing the timing or magnitude of the changes.Monetary Policy, Taylor Rule, Local Estimation, Nonlinearity, Nonparametric, Monetary Policy; Taylor Rule; Local Estimation; Nonlinearity; Nonparametric; Structural Vector Autoregression; Autoregressive Conditional Heteroskedasticity;
