Ultrastructural changes in dermal pig skin after exposure to heat and electric energy and acid and basic solutions

In order to describe the ultrastructure of the histopathological changes in dermis after exposure to electrical energy, heat energy and acid and basic solutions the skin of fully anaesthetized Danish Landrace pigs were exposed to direct current, heat (80 degrees C and 450 degrees C) and acid and basic solutions. Biopsies were obtained immediately after the exposure from all types of injury. Biopsies from the cathode areas biopsies were also taken on day 1 and day 2.5 in order to describe the initial calcium deposits. Homogeneous collagen fibres without any birefringence from heat exposed areas were ultrastructurally composed of filamentous materials. Collagen fibres with fine densely spaced cross-striation from cathode areas and areas exposed to basic solutions were shown ultrastructurally to consist of parallelly arranged collagen fibrils with regular waves. It is concluded that the cross-striation of the collagen fibres observed in polarized light are due to a periodic change in the orientation of the fibres seen as waves of the fibres. The ultrastructure of dermal cells were similar to that of epidermal cells following the different types of influence. Characteristically the nuclei were condensed following heat and more electron-lucent following direct current (d.c.) and acid and basic solutions. In cathode areas and areas influenced by basic solutions the electron-lucent nuclei contained fine fibrils. The ultrastructural study supports the suggestion from light microscopic studies that the morphology of anode and cathode lesions shows resemblance to acid induced and basic induced lesions, respectively. Apatite crystals were observed on day 2.5 at the periphery of the collagen fibrils and in the matrix of elastic fibres.     

Deny and Attack or Concede and Correct? Image Repair and the Politically Scandalized

In the wake of recent political scandals, pundits have argued that the way a politician reacts to a scandal can make or break said politician's relationship with constituents and future in elected office. Some politicians concede guilt immediately, apologize, promise to take corrective action, and possibly open the door to moving on with their careers. Others deny culpability and attack their accusers, hoping to quickly put accusations behind them, change the subject, and channel public attention in a different direction. Does conceding guilt after a scandal breaks and offering to take corrective action to solve the problem help ameliorate the issue, or does it push the public away even further? Does denying involvement in a scandal and attacking the accuser compound the problem, or can it evoke positive feelings? This research uses an experimental design to test individuals’ reactions to how politicians act after being accused of a personal scandal (in this case, an inappropriate relationship with a staffer). Results illustrate that a strategy involving denial and attacking accusers can spur positive evaluations of who a politician is and what that politician will do in the future, while the performance of conceding and taking corrective action is mixed at best.     

Caught in quicksand? Compliance and legitimacy challenges in using regulatory sandboxes to manage emerging technologies

Regulatory sandboxes have become the latest development in regulatory reform, starting first in financial regulation and now expanding to other sectors. While sandboxes offer notable potential benefits for managing emerging technologies, achieving desirable policy outcomes with this novel regulatory instrument also comes with technical and political challenges. This article offers a framework to characterize regulatory sandboxes in any sector, involving a blend of (1) approval regulation with broad-based standards, (2) restricted discretion by the regulator for specific norms, (3) process-oriented regulation, (4) an outcomes-orientation, and (5) structured regulator–regulatee information sharing or dialogue. Using this model, the article outlines issues in compliance and legitimacy, including in trust and accountability, responsive enforcement, the politics of participation, and post-sandbox oversight. The article concludes by calling for greater scrutiny when considering implementing a sandbox instrument, with attention to sector-specific concerns, and offering directions for empirical evaluation of regulatory sandboxes.

Austen Chamberlain and Britain's Relations with France, 1924–1929

Several historians have suggested that Austen Chamberlain's Francophile tendencies during his period as foreign secretary between 1924 and 1929 were the defining features of his European diplomatic strategy. By examining four key events: the rejection of the Geneva Protocol, the conclusion of the Treaty of Locarno, the Anglo–French Compromise on disarmament and the negotiation of the Kellogg-Briand Pact, this article argues that Chamberlain's relationship with the French was not entirely harmonious. After the high point of Locarno, Britain's relations with France became increasingly tense because of Chamberlain's growing disillusionment with Briand's willingness to pursue a diplomatic agenda that did not have at its heart a reinvigorated Entente Cordiale.     

Taking Action to Stop Violence: A Study on Readiness to Change Among Male Batterers

The Transtheoretical Model of Change (TTM) predicts that matching interventions with a person’s readiness to change should improve treatment outcomes. This cross-sectional correlational study examined characteristics that affected self-reported readiness to change abusive behavior among a sample of 109 men in a 52-week batterer treatment program. Participants completed measures of anger/hostility, readiness to change, manipulative parenting, and self-esteem. Results indicated that contemplation of the impact of abuse has the highest unique relationship with self-reported taking action to stop violence. Moreover, physical aggression and manipulative parenting account for significant variance in the scores associated with self-reported taking action to stop violence as well. These findings suggest that interventions aimed at moving clients into contemplation, and reducing physical aggression and manipulative parenting styles, may increase the likelihood that batterers will take action to stop violence.     

Teen Choices,an Online Stage-Based Program for Healthy,Nonviolent Relationships: Development and Feasibility Trial

This article describes the theoretical foundation, development, and feasibility testing of an online, evidence-based intervention for teen dating violence prevention designed for dissemination. Teen Choices, a program for healthy, nonviolent relationships, relies on the transtheoretical model of behavior change and expert system technology to deliver assessments and feedback matched to stage of change for using healthy relationship skills. The program also tailors feedback to dating status, risk level, and other key characteristics. Ninety-nine students from high schools in Tennessee and Rhode Island completed a Teen Choices session and 97 completed an 11-item acceptability evaluation. Of participants, 100% completed the intervention session as intended. Evaluations of the program were favorable: 88.7% agreed the program feedback was easy to understand, and 86.7% agreed that the program could help people develop healthier relationships. Findings provide encouraging evidence of the acceptability and feasibility of this approach to dating violence prevention.     

Witness testimony from the Church Committee hearings on covert action, 1975

One of the most controversial uses of intelligence by the United States is covert action – secret efforts to change the course of history by intervening secretly into the affairs of other nations or factions. In 1975, the Church Committee held hearings on this subject – a rarity – and four expert witnesses laid out for the panel their recommendations for changes in the conduct of covert action. This dip into the intelligence archives by Intelligence and National Security reveals that much has changed in the world of covert action since 1975, with some of the witness recommendations coming to fruition and others widely ignored.
