Institutional Change and Conflict Regulation: The Anglo-Irish Agreement (1985) and the Mechanisms of Change in Northern Ireland

This article uses historical institutionalist theory to assess the impact of the Anglo-Irish Agreement of 1985 – often seen as the first step towards gradualist change in the role of the state in Northern Ireland. It uses new data to show how the elites who initiated the process conceived of it and to identify the mechanisms producing change. The study shows that the mechanisms of institutional change identified in comparative studies of industrial policy and welfare state development are also to be found in processes of intergovernmental ethnic conflict regulation. In turn, it highlights a mechanism of institutional change – ‘wedging’ – not discussed in the literature.     

Intimate partner violence, relationship status, and protective orders: does "living in sin" entail a different experience?

The legal status of women's intimate relationships may allow for different experiences with intimate partner violence (IPV) and the protections received from the criminal justice system. There has been limited research examining differences in IPV and protective orders for women in marital and cohabiting intimate relationships. This study examines differences in experiences with IPV and factors related to protective orders: stipulations, violations, and perceived efficacy in a sample of married (n = 392) and cohabiting (n = 307) women with protective orders. Results suggest (a) married and cohabiting women are significantly different on a number of demographic characteristics; however, after controlling for these demographic differences, (b) married and cohabiting women's experiences with IPV are similar in almost all dimensions, except with the psychological tactic of degradation; and (c) married and cohabiting women receive similar protective order stipulations, experience similar rates of violations, and have the same overall perceptions of safety, freedom, and effectiveness pertaining to the domestic violence order. Implications for policy are discussed.     

The promise of primary prevention home visiting programs: a review of potential outcomes

Home visitation (HV) is a promising service delivery model, despite a history of mixed documented results. Compiling results on the promising family and child development outcomes in the HV literature has utility for current programs and those under development. We review traditional outcomes (e.g., child maltreatment prevention) from the literature on HV, but we also present nontraditional outcomes (e.g., community connection) that may be relevant for future evaluations. Programs that document their implementation and study their outcomes through a thoughtful, planned process may capture important and much needed information on strengthening families through HV.     

Variation in nuclear DNA concentrations during urination

This study examined the cellular origin and concentration of nuclear DNA in human urine. Ten subjects provided two entire, first-morning voids: one as a single specimen and one as a consecutive series of samples. The serial samples were centrifuged, organically extracted, and quantified by slot-blot analysis. Total DNA concentrations ranged from 0.02 to 21.3 ng/mL for the males and 25.0 to 96.9 ng/mL for the females. The female samples were found to contain numerous vaginal epithelial cells. DNA was detected in all of the serial samples of nine subjects; however, the DNA concentrations varied considerably. With six subjects, the DNA concentration of the first serial sample was at least three times greater than that of the entire void. DNA was only detected in the first 21% of the void from one male subject. The results of this study have implications for the collection of urine samples.     

Rodents as taphonomic agents: bone gnawing by brown rats and gray squirrels

Passive infrared technology was used to film diurnal and nocturnal scavenging behavior of brown rats and gray squirrels at the University of Tennessee's Anthropological Research Facility. This direct documentation demonstrated that brown rats modified fat-laden cancellous bone while gray squirrels generally gnawed the thicker bone cortices only after fats had leached away. A case study placed in a shaded portion of the Facility indicated the postmortem interval for initial gnawing by gray squirrels was slightly over 30 months. An examination of 53 human skeletons in the William M. Bass Forensic Skeletal Collection revealed that 10 cases had gnaw marks consistent with those made by gray squirrels. One of the 10 cases had been gnawed within 16 months of time-since-death, while the remaining nine had postmortem intervals >30 months. Additional observed modifications made to nonhuman bone by gray squirrels indicate that squirrel gnaw marks on bone can serve as a minimal estimate of time-since-death in a temperate environment similar to that of East Tennessee.     

Comparative analysis of gamma-hydroxybutyrate and gamma-hydroxyvalerate using GC/MS and HPLC

This paper describes two analytical techniques used to separate and quantify gamma-hydroxybutyrate (GHB) and gamma-hydroxyvalerate (GHV). The first technique was a N,O-bis(trimethylsilyl)triflouro-acetimide-trimethylchlorosilane derivatization, followed by gas chromatography/mass spectrometry analysis using an HP-5 capillary column at a rate of 1.0 mL/min with a run time of 9.25 min. This technique was found to be sensitive (LOD 1 pg on column) and gave a low average error (5%) in a beverage study. When supplemented by a surrogate spike, the method yielded 97% analyte recovery from beverages. The second technique was high-performance liquid chromatography/UV (HPLC/UV) using a C-18 column with a (20:80% v/v) methanol:dibasic phosphoric buffer (10 mM, pH 3) at a rate of 1.00 mL/min with a run time of 7.5 min. UV detection occurred at 254 nm. This method was found to be less sensitive (LOD 0.05 microg on column) for direct analysis of aqueous samples. To remove interferences seen in the beverage study, a liquid-liquid extraction before HPLC analysis was tested. However, a decreased sensitivity (LOD 100 microg on column) and irreproducible peak profiles resulted.
