The impact of leader turnover on the onset and the resolution of WTO disputes

When national leaders are replaced, the incoming leader often represents different interests to those of his predecessor. Such shifts in national priorities affect both the onset of WTO disputes and the resolution of ongoing disputes. In particular, leader turnover increases the likelihood that a nation will be involved in a WTO dispute as either plaintiff or defendant, and, if a dispute is ongoing, then leader change in a defendant state increases the likelihood of significant concessions by the defendant. The impact of leader change on both the initiation and settlement of disputes is greater in non-democratic states than democratic states.     

Majority Party Power and Procedural Motions in the U.S. Senate

While the metaphor of House parties as cartels is widely accepted, its application to the Senate is difficult as the majority party lacks the power to unilaterally manipulate rules and pass legislation. Nevertheless, several scholars have argued that the Senate majority party is able to employ nondebatable motions to table to exclude unwanted amendments with procedural rather than substantive votes. Does the motion to table yield negative agenda control or special party influence? Using an analysis of individual Senators' behavior on thousands of votes and an assessment of interest group scores, we find that motions to table do not elicit higher party influence or provide much political cover. A desire to speed up the legislative process, rather than to insulate members from electoral scrutiny, seems to motivate the use of motions to table.     

The sinking of the Lusitania: reviewing the evidence.

On the afternoon of 7 May 1915 the Cunard Liner Lusitania was torpedoed by a German U-boat whilst en route to Liverpool. Consequently in sank with the loss of 1,195 lives. A series of investigative and formal research exercises, undertaken in the light of eye-witness accounts of the events surrounding that tragedy, has given rise to a number of hypotheses concerning the loss of this vessel. In this paper all the available evidence concerning the attack, and the one or more explosions that occurred, is summarised. The conclusions regarding the torpedo effects and the most likely causes of the secondary events are reported.     

State Visits and Leader Survival

Why do political leaders travel abroad? In this article, we propose an informational mechanism linking in‐person diplomacy to leader survival. A foreign power visits an incumbent in order to reap a future policy concession; the visit is only worth the effort if the incumbent remains in power long enough to deliver on the deal. A diplomatic visit thus provides a visible and credible signal of the visitor's high confidence in the incumbent's stability in office. Domestic opponents, facing incomplete information as to the incumbent's strength, observe the signal and are deterred from mounting a challenge. Using data on U.S. diplomatic visits from 1960 to 2013, we find strong empirical support for our predictions: A visit with the U.S. president substantially reduces the risk of a leader's removal from office.     

Determination of Trace Elemental Concentrations in Document Papers for Forensic Comparison Using Inductively Coupled Plasma–Mass Spectrometry

Abstract:  With improvements in manufacturing procedures, comparing physical characteristics of paper samples may not offer sufficient discrimination among different vendors. In this work, the potential to differentiate paper samples based on trace element concentrations was investigated. Paper samples from two different vendors were microwave-digested and trace element concentrations (Mg, Al, Mn, Fe, Sr, Y, Ba, Ce, and Nd) were determined using inductively coupled plasma–mass spectrometry. Differences in concentration were assessed statistically using two-way ANOVA and Tukey's honestly significant differences test. Elemental concentrations were shown to be consistent across a single sheet as well as within a single ream of paper for each vendor. Reams from vendor A were differentiated based on Al and Ba concentration while reams from vendor B were differentiated based on Mg, Mn, and Sr concentrations. Paper was differentiated according to vendor based on significant differences in Ba, Sr, Ce, and Nd concentrations.     

The limits of individual control? Perceived officer power and probationer compliance

Interactions between correctional agents and the offenders they supervise are assumed to be highly contingent upon latent power dynamics. Yet, currently there is little research that differentiates the bases of power used by correctional personnel. The present study drew on a classic typology to examine the role of power in probation supervision. Perceptions of power and their impact on probationers' compliance were examined using data collected from self-report surveys and case files of 376 misdemeanor probationers. Although the results for perceived power were similar to those of prior research, the current study's findings largely did not support the expected relationship between bases of power and compliance with the conditions of probation. The theoretical and practical implications of these results are discussed.     

Unemployment among women: examining the relationship of physical and psychological intimate partner violence and posttraumatic stress disorder

Prior research has demonstrated that intimate partner violence (IPV) is associated with employment instability among poor women. The current study assesses the broader relationship between IPV and women's workforce participation in a population-based sample of 6,698 California women. We examined past-year IPV by analyzing specific effects of physical violence, psychological violence, and posttraumatic stress disorder (PTSD) symptoms as predictors of unemployment. Results indicated substantial rates of unemployment among women who reported IPV, with rates of 20% among women who experienced psychological violence, 18% among women who experienced physical violence, and 19% among women with PTSD symptoms. When the relationship was adjusted for demographic characteristics and educational attainment, PTSD (adjusted odds ratio [AOR] = 1.60; 95% confidence interval [CI] = 1.22, 2.09) and psychological violence (AOR = 1.78; 95% CI = 1.36, 2.32), but not physical violence, were associated with unemployment. Implications for supported employment programs and workplace responses to IPV are discussed.     

The relationship between job status,interviewing experience,gender, and police officers' adherence to open‐ended questions

Purpose. The current study examined whether several factors related to the job and demographic profile of police officers are associated with adherence to best‐practice guidelines when interviewing children. Method. One hundred and seventy‐eight police officers completed a standardized (simulated) interview regarding an allegation of abuse by a 5‐year‐old child. Immediately prior to this interview, details were obtained from the officers' regarding their job status, gender, interview experience, the timing and nature of prior training/supervision, and experience outside the policing profession with young children. Results. The results showed that timing of training was the only factor that related to interview performance. The proportion of open‐ended questions among participants who completed their interviewer training course less than 1 month prior to the simulated interview was better than those who completed the training earlier. Interestingly, the performance of the latter group was identical to that of a group of participants who had not yet received any formal interview training. The implications of the findings are discussed, along with directions for future research.
