Criminal history and assaults on intimate partners by Mexican American and non-Mexican White college students

This study analyzed a sample of 348 college students to examine the role that criminal history and Mexican ethnicity play in predicting intimate partner violence. Respondents who committed crimes in the past (before the age of 15) had a higher probability of severely physically assaulting a partner than those respondents who had committed crime later in life (after the age of 15). A history of property crime was found to be a better predictor of severe partner assault than a history of violent crime. The results support a generalist perspective on crime, which states that most individuals typically do not commit one type of crime solely but commit a variety of different crimes (property and violent). This study also found differences between Mexican American and non-Mexican White students in reference to minor assaults on a partner.     

The Effect of “China Bashing” on Sino-American Relations

Many scholars argue that a sizable share of the news about China published in U.S. newspapers engages in ??China Bashing.?? This paper quantifies the extent of the bashing and examines its effect on Sino-American relations. To measure bashing, I develop an index based on the count of articles in major U.S. newspapers that are related to China and also touch on one or more of the following issues: human rights, Tibet, democracy, child labor, and repression. I repeat this process for newspapers from Australia and New Zealand to net out ??fundamental?? news. To examine the effect of the bashing on Sino-American relations, I use the China-US relations score of Yan et al. (Zhongwai guanxi dingliang yuce, [?????????????; Quantitative Forecasts of China??s Foreign Relations]. Beijing, China: Shijie heshi chubanshe, 2009, Zhongwai guanxi jianlan 1950-2005??Zhongguo yu daguo guanxi dingliang hengliang [??????????1950-2005???й???????????????; China??s Foreign Relations with Major Powers by the Numbers 1950-2005]. Beijing: Gaodeng jiaoyu chubanshe, 2010) and estimate a dynamic transfer model with the constructed bashing index, as well as other control variables. The results indicate that a one-standard-deviation shock in bashing leads to a 0.038 point decline in Yan??s Sino-American index after about four months. The results further imply that the cumulative long-run effect of persistent China bashing is equivalent to about 50?% of the decline in Sino-American relations that followed the U.S. bombing of the Chinese Embassy in Belgrade on May 7, 1999, the worst shock to Sino-American relations during the sample period, 1990 to 2010.     

Therapeutic Jurisprudence in Practice: Changes in Family Treatment Court Norms Over Time

Family treatment court (FTC) is an example of an increasing number of problem‐centered courts currently operating in the United States. Problem‐centered courts such as FTC encompass the ideas of therapeutic jurisprudence but operate within the broader court system. Presented are the results of an FTC case study that seeks to understand the evolution of courtroom norms and practice over time. Observations of courtroom interactions and interviews with courtroom personnel show that initial observations are consistent with the ideals of therapeutic jurisprudence. However, over time, daily demands and pressures on the courtroom undermine the therapeutic approach.     

The Dynamics of Partisan Conflict on Congressional Approval

Partisan divisions in American politics have been increasing since the 1970s following a period where scholars thought parties were in decline. This polarization is observed most frequently within the debates and deliberation across issues within Congress. Given that most studies of public opinion place the behavior of elites at the center of public attitudes, surprisingly little research examines the effect of partisan conflict on the mass public. This research examines quarterly congressional approval data from 1974 to 2000 to determine the consequences, if any, of party conflict on the dynamics of congressional approval. The findings indicate that over-time changes in partisan conflict within Congress have a direct and lasting effect on how citizens think about Congress.     

Targets and Tactics: Testing for a Duality within Al Qaeda’s Network

One prevailing view treats Al Qaeda as a monolithic entity with a global network of affiliates. Yet, certain affiliates appear more committed to local political and territorial goals – parochial, not global, terrorists. We construct a classification scheme to differentiate affiliates conceptually and empirically, and then track their types over time. We sort Al Qaeda’s network of affiliates using a principal components analysis of terrorist attacks from 1988 to 2012. We show that this aids in identifying latent affiliate types, and interpreting shifts in behavior. We find that despite Al Qaeda’s anti-western rhetoric, there exists a global-parochial divide in which most affiliates are parochial – with anti-Western groups pursuing local political goals even when Western targets remain. By providing an empirical strategy to identify which affiliates are more or less aligned with global terrorism, this research holds implications for the literatures on terrorism and civil war, terrorism and democracy, and the effects of counterterrorism.     

Quantitative analysis of multiple illicit drugs in preserved oral fluid by solid-phase extraction and liquid chromatography–tandem mass spectrometry

We present a validated method for the simultaneous analysis of basic drugs which comprises a sample clean-up step, using mixed-mode solid-phase extraction (SPE), followed by LC–MS/MS analysis. Deuterated analogues for all of the analytes of interest were used for quantitation. The applied HPLC gradient ensured the elution of all the drugs examined within 14 min and produced chromatographic peaks of acceptable symmetry. Selectivity of the method was achieved by a combination of retention time, and two precursor-product ion transitions for the non-deuterated analogues. Oral fluid was collected with the Intercept^®, a FDA approved sampling device that is used on a large scale in the US for workplace drug testing. However, this collection system contains some ingredients (stabilizers and preservatives) that can cause substantial interferences, e.g. ion suppression or enhancement during LC–MS/MS analysis, in the absence of suitable sample pre-treatment. The use of the SPE was demonstrated to be highly effective and led to significant decreases in the interferences. Extraction was found to be both reproducible and efficient with recoveries >76% for all of the analytes. Furthermore, the processed samples were demonstrated to be stable for 48 h, except for cocaine and benzoylecgonine, where a slight negative trend was observed, but did not compromise the quantitation. In all cases the method was linear over the range investigated (2–200 μg/L) with an excellent intra-assay and inter-assay precision (coefficients of variation <10% in most cases) for QC samples spiked at a concentration of 4, 12 and 100 μg/L. Limits of quantitation were estimated to be at 2 μg/L with limits of detection ranging from 0.2 to 0.5 μg/L, which meets the requirements of SAMHSA for oral fluid testing in the workplace. The method was subsequently applied to the analysis of Intercept^® samples collected at the roadside by the police, and to determine MDMA and MDA levels in oral fluid samples from a controlled study.     

Comparing ethics education in medicine and law: combining the best of both worlds

This article compares various models of ethics education and how these models are employed by both medical schools and law schools. The authors suggest ways in which each profession can enhance their ethical teaching and argue that ethics education in both medicine and law should combine the best elements of each education model, thereby producing graduates who are more knowledgeable and appreciative of ethical issues in practice.     

Correlation of Delta9-tetrahydrocannabinol concentrations determined by LC-MS-MS in oral fluid and plasma from impaired drivers and evaluation of the on-site Dräger DrugTest

Oral fluid (collected with the Intercept((R)) device) and plasma samples were obtained from 139 individuals suspected of driving under the influence of drugs and analyzed for Delta(9)-tetrahydrocannabinol (THC), the major psychoactive constituent of cannabis, using a validated quantitative LC-MS-MS method. The first aim of the study was to investigate the correlation between the analytical data obtained in the plasma and oral fluid samples, to evaluate the use of oral fluid as a 'predictor' of actual cannabis influence. The results of the study indicated a good accuracy when comparing THC detection in oral fluid and plasma (84.9-95.7% depending on the cut-off used for plasma analysis). ROC curve analysis was subsequently used to determine the optimal cut-off value for THC in oral fluid with plasma as reference sample, in order to 'predict' a positive plasma result for THC. When using the LOQ of the method for plasma (0.5 ng/mL), the optimal cut-off was 1.2 ng/mL THC in oral fluid (sensitivity, 94.7%; specificity, 92.0%). When using the legal cut-off in Belgium for driving under the influence in plasma (2 ng/mL), an optimal cut-off value of 5.2 ng/mL THC in oral fluid (sensitivity, 91.6%; specificity, 88.6%) was observed. In the second part of the study, the performance of the on-site Dr?ger DrugTest for the screening of THC in oral fluid during roadside controls was assessed by comparison with the corresponding LC-MS-MS results in plasma and oral fluid. Since the accuracy was always less than 66%, we do not recommend this Dr?ger DrugTest system for the on-site screening of THC in oral fluid.
