The Morality of Divestment

Divestment from companies that produce or heavily utilize fossil fuels has become one of the biggest issues in the contemporary moral debate surrounding climate change. Universities and other institutions are being asked to divest themselves of their fossil fuel–related investments. In this article I argue that, while the case for divestment is morally strong, not all of the arguments used to support divestment are equally strong. Moreover, which of these arguments is employed matters a great deal for the strength of the conclusions regarding divestment. There are two major groups of arguments: what I call positive arguments for divestment, which stem from the claim that divestment is a response to general duties to take action to prevent dangerous climate change, and what I call negative arguments, which stem from a duty not to cause harm. In this article I will briefly characterize what divestment means and to whom it applies. I will then look at negative and positive duty accounts of the duty to divest before looking at the standard objections to both. Objections have tended to cohere around the claims that divesting is inconsistent, useless and/or harmful, or should be abandoned for better options to avoid dangerous climate change.     

The effects of chemical and heat maceration techniques on the recovery of nuclear and mitochondrial DNA from bone

Forensic anthropologists use a number of maceration techniques to facilitate skeletal analysis of personal identity and trauma, but they may unwittingly eliminate valuable DNA evidence in the process. This study evaluated the effect of 10 maceration methods on gross bone structure and the preservation of DNA in ribs of 12 pigs (Sus scrofa). A scoring system was applied to evaluate the ease of maceration and resulting bone quality while DNA purity was quantified by optical densitometry analysis, followed by polymerase chain reaction (PCR) amplification of three mitochondrial and three nuclear loci. The results demonstrated that while mitochondrial DNA could be amplified for all experiments, cleaning treatments using bleach, hydrogen peroxide, ethylenediaminetetraacetic acid/papain, room temperature water and detergent/sodium carbonate followed by degreasing had low DNA concentrations and failed to generate nuclear PCR products. In general, treatments performed at high temperatures (90 degrees C or above) for short durations performed best. This study shows that traditionally "conservative" maceration techniques are not necessarily the best methods to yield DNA from skeletal tissue.     

He Versus She: A Gender-Specific Analysis of Legal and Extralegal Effects on Pretrial Release for Felony Defendants

The current study sought to identify significant predictors of pretrial processing for both male and female defendants in an aggregate sample. The data used in this study were taken from the State Court Processing Statistics, 1990–2000: Felony Defendants in Large Urban Counties (Bureau of Justice Statistics, 2004 Bureau of Justice Statistics . ( 2004 ). State court processing statistics, 1990–2000: Felony defendants in large urban counties [ Computer file ]. Ann Arbor , MI : Inter-University Consortium for Political and Social Research . [Google Scholar]). The original sample included a total of 87,437 felony cases. The relationships between relevant independent variables and 5 separate dependent variables (denial of bail, non-financial release, amount of bail set, making bail, and pretrial incarceration) were analyzed using both multivariate regression and Z-score comparisons within gender-specific models. Findings suggest that the effects of certain independent variables on pretrial release decisions and outcomes are different between the gender-specific models.
