The Dynamic Relationship between Unhealthy Weight Control and Adolescent Friendships: A Social Network Approach

Although adolescence marks a vulnerable stage for peer influence on health behavior, little is known about the longitudinal and dynamic relationship between adolescent friendship and weight control. The current study aims to explain these dynamic processes among a sample of 1156 American adolescents in grades 9–11 (48.6% girls, 23.4% European American, 25.2% African American) from the National Longitudinal Study of Adolescent Health. Stochastic actor-oriented models were fit to examine changes in friendship networks and unhealthy weight control across two waves. The findings support a bidirectional relationship where weight control predicts future friendship seeking and friendship seeking predicts future weight control. The findings also indicate that adolescents prefer friends with similar weight control patterns. Taken together, the results of the current study indicate that adolescent friendships play an integral role in the development of unhealthy weight control and thus can be used to identify adolescents at risk and serve as targets within preventive interventions.     

Evidenz und Expertise im vorparlamentarischen Gesetzgebungsprozess: Die Rolle von Verwaltung und externen Experten

Der Evidence‐Based Policy‐Ansatz hat international Reformen ausgelöst und Studien zum Verhältnis von Wissen und Politik angestossen, wobei ein klares Verständnis von “Evidenz” nach wie vor fehlt. In diesem Artikel wird eine Typologie politikrelevanter Wissensarten entwickelt, die zwischen systematischer Evidenz und personengebundener Expertise sowie zwischen den Politikdimensionen Policy, Politics und Polity unterscheidet. Auf dieser konzeptionellen Grundlage wird empirisch erfasst, welches Wissen die Verwaltung und externe Experten während der bisher kaum untersuchten Frühphase von Gesetzgebungsverfahren auf Bundesebene beitragen. Es zeigt sich, dass die federführenden Verwaltungsakteure kaum über Expertise verfügen, die für den Gesetzgebungsprozess relevant wäre, doch versuchen sie, ihre Wissenslücken je nach Dimension unterschiedlich zu kompensieren. Externe Experten leisten einen bescheidenen Wissensbeitrag, weshalb ihre Beteiligung primär als Mittel für die politische Kompromissfindung verstanden werden muss. Dies eröffnet aus demokratietheoretischer Sicht Diskussionsbedarf.     

Remembering Civil Patrols in Joyabaj, Guatemala

During the civil war in Guatemala, which only ended with the signing of the comprehensive Peace Accords in December 1996, the military organised the male population throughout the Guatemalan highlands into civil defence patrols (Patrullas de Autodefensa Civil, PAC). Initially set up to help the military to win the war, they eventually evolved into a local power player in their own right. Although the patrols were dismantled in 1996, former patrols still influence daily life. This paper examines how, at the municipal level, current memories of the civil war, especially of the civil defence patrols, still shape perceptions, actions, and social relations. These are marked by fear, prejudice, and distrust, thereby creating important impediments for erasing the legacy of violence and building local democracy and civil society.     

Unspeakable Pasts as Limit Events: The Holocaust, Genocide, and the Stolen Generations

This article examines the role of testimony in the production of the memory of the Holocaust and the practice of forcible removals in Australia as "limit events". A "limit event" is an event or practice of such magnitude and profound violence that its effects rupture the otherwise normative foundations of legitimacy and so-called civilising tendencies that underlie the constitution of political and moral community. The references are the stories of removal collated in Bringing Them Home , and eyewitness testimonies from the trial of Adolf Eichmann in Jerusalem in 1961. By situating the stolen generations and the Eichmann trial as limit events, I argue that the effects of witnessing and story-telling exposed a cultural semantics of what was speakable and unspeakable in the narratives of judging historical injustice and remembering past traumas.     

Genocide yet again: Scenes of Rwanda and Ethical Witness in the Human Rights Memoir

This article investigates three recent human rights memoirs that chronicle the Rwandan genocide of 1994: Emergency Sex (and other desperate measures): True Stories from a War Zone, Shake Hands with the Devil: the failure of humanity in Rwanda, and The Zanzibar Chest: a memoir of love and war. I use these memoirs to explore the complexities of bearing witness to ethnic violence and war as an autobiographical subject shaped by the memory of historical atrocity — as a besieged self in traumatic occupations of the UN protector (Roméo Dallaire), lawyer (Kenneth Cain), and war correspondent (Aidan Hartley). Finally, I suggest that the authors of these memoirs are secondary witnesses, claimants to ethical truths and writers of atrocity testimony that complicate the burgeoning life‐telling compulsion of what is and who can claim to be a genocide victim. “Your mind with time, in fact, doesn't erase things that are traumas. It makes them clearer. They become digitally clearer and then you are able to sit back and all of a sudden have every individual scene come to you instead of the massive blur of many scenes I saw every day. The accumulation of the spirits that would come to you at night in the form of eyes, thousands of eyes, some mad, some simply there, and others bewildered, innocent children and adults, all that accumulated to the fact that I simply totally broke down”. (Roméo Dallaire) “What's true is that we didn't understand at the time the full magnitude of what was happening. I was an ant walking over the rough hide of an elephant. I had no idea of the scale of what I was witnessing. And when I did become aware I discovered Rwanda was way beyond my limited talents as a correspondent”. (Aidan Hartley, The Zanzibar Chest) “I don't know who saved the honor of mankind during my time in the field, but I do know that an ancestral memory of tyranny commands me not to keep silent. There is no ambiguity here. I am a witness. I have a voice. I have to write it down”. (Kenneth Cain, Emergency Sex)     

Minor or adult? Introducing decision analysis in forensic age estimation

Nowadays, forensic age estimation takes an important role in worldwide forensic and medico-legal institutes that are solicited by judicial or administrative authorities for providing an expert report on the age of individuals. The authorities’ ultimate issue of interest is often the probability that the person is younger or older than a given age threshold, which is usually the age of majority. Such information is fundamental for deciding whether a person being judged falls under the legal category of an adult. This is a decision that may have important consequences for the individual, depending on the legal framework in which the decision is made. The aim of this paper is to introduce a normative approach for assisting the authority in the decision-making process given knowledge from available findings reported by means of probabilities. The normative approach proposed here has been acknowledged in the forensic framework, and represents a promising structure for reasoning that can support the decision-making process in forensic age estimation. The paper introduces the fundamental elements of decision theory applied to the specific case of age estimation, and provides some examples to illustrate its practical application.     

Incomplete contracts and competition: another look at fisher body/general motors?

In this paper we analyze the problem of the enforcement of incomplete contracts with endogenous outside options. Some of the equilibria we outline may reverse one of the main results presented in the standard literature. We then revisit the literature on the highly debated Fisher Body/General Motors merger and suggest an explanation based on GM??s need to control the Fisher brothers?? outside options.
