Correlating Alpine glaciation with Adriatic sea-level changes through lake and alluvial stratigraphy
Resumo:
We compare lake and alluvial stratigraphy along a frame connecting the southern Alpine foothills and the Adriatic Sea, with the aim of matching the effects of Alpine glaciation and sea-level changes on sedimentation during the last glacial cycle. The palynostratigraphy of Lake Fimon provided proxies for regional vegetation and climate change and was coupled with sediment petrography, loss on ignition and magnetic susceptibility, disentangling alluvial phases from fluvioglacial activity related to culminations of the southeastern Alpine glaciers. The Fimon area was not reached by alluvial fans during the penultimate glacial maximum, nor by the sea transgression during the last interglacial, but a closed lake soon developed at the Eemian onset due to enhanced rainfall. Sea-level fall at glacial inception triggered the entrenchment of the drainage network in the plain reaching the outer Fimon Basin. Slow aggradation, but no sign of fluvioglacial activity, lasted to 38.2 +/- 1.45 cal. ka BP, when a major forest withdrawal took place, coeval to the spread of alluvial fans. By 27.5 perpendicular to 0.5 cal. ka BP the Fimon Basin was dammed by the Brenta outwash system. The main step of of forest recovery commenced at around (15.8) cal. ka BP, when apex trenching of the outwash fans was triggered by the glacier's decay. Copyright (C) 2011 John Wiley & Sons, Ltd.

Privacy has now become a major topic not only in law but in computing, psychology, economics and social studies, and the explosion in scholarship has made it difficult for the student to traverse the field and identify the significant issues across the many disciplines. This series brings together a collection of significant papers with a multi-disciplinary approach which enable the reader to navigate through the complexities of the issues and make sense of the prolific scholarship published in this field.
The three volumes in this series address different themes: an anthropological approach to what privacy means in a cultural context; the issue of state surveillance where the state must both protect the individual and protect others from that individual and also protect itself; and, finally, what privacy might mean in a world where government and commerce collect data incessantly. The regulation of privacy is continually being called for and these papers help enable understanding of the ethical rationales behind the choices made in the sphere of regulation of privacy.
The articles presented in each of these collections have been chosen for the quality of their scholarship and their utility to the researcher, and feature a variety of approaches. The articles which debate the technical context of privacy are accessible to those from the arts and humanities; overall, the breadth of approach taken in the choice of articles has created a series which is an invaluable and important resource for lecturers, researchers and student.

This article addresses the relative absence of class-based analysis in theatre and performance studies, and suggests the reconfiguration of class as performance rather than as it is traditionally conceived as an identity predicated solely on economic stratification. It engages with the occlusion of class by the ascendancy of identity politics based on race, gender and sexuality and its attendant theoretical counterparts in deconstruction and post-structuralism, which became axiomatic as they displaced earlier methodologies to become hegemonic in the arts and humanities. The article proceeds to an assessment of the development of sociological approaches to theatre, particularly the legacy of Raymond Williams and Pierre Bourdieu. The argument concludes with the application of an approach which reconfigures class as performance to the production of Declan Hughes's play Shiver of 2003, which dramatizes the consequences of the dot.com bubble of the late 1990s for ambitious members of the Irish middle class.

Violence can threaten individual wellbeing and tear at the social fabric of communities. At the same time, suffering can mobilize social coping and mutual support. Thus, the backdrop of political violence increases risk factors and stimulates resilience. The current study examined the moderating role of social coping as reflective of risk and resiliency in Northern Ireland, a setting of protracted conflict. Specifically, structural equation modeling was used to investigate whether social coping protects from or exacerbates the negative impact of sectarian crime and nonsectarian crime on maternal mental health (N?=?631). Nonsectarian crime predicted greater psychological distress for mothers in Belfast. Mixed support was found for the buffering and depletion moderation hypotheses; social coping functioned differently for nonsectarian crime and sectarian crime. Greater social coping buffered mothers' psychological distress from the negative effects of nonsectarian crime, but exacerbated maternal mental health problems when facing sectarian crime. Results suggest that social coping is a complex phenomenon, particularly in settings of protracted political violence. Implications for interventions aimed at alleviating psychological distress by enhancing mothers' social coping in contexts of intergroup conflict are discussed. We would like to thank the many families in Northern Ireland who have participated in the project. We would also like to express our appreciation for the project staff, graduate students, and undergraduate students at the University of Notre Dame and the University of Ulster.

This article examines the work and roles of HR managers in the Irish recession. It tests the validity of three competing views about the future of HR: that the profession needs to become a business partner; that it is knee-deep in a legitimacy crisis; and that it is fragmenting by being unable to cope with the complexity of modern organizational life. Three key findings emerge from the research. First, HR managers have gained greater influence in business decision-making, but much of this influence arises from short-run retrenchment measures. Second, many HR managers remain committed to long established professional values and ideas of good practice. Third, modern HR managers are developing a professional identity that allows them to perform multiple, competing roles. These findings challenge existing arguments about the effects of the current recession. They also speak to ongoing debates about changing HR roles by showing how HR managers remain adept at making pragmatic adaptations to secure their role in organizational life. © The Author(s) 2012.

In a recent study, we reported that the accurate perception of beat structure in music ('perception of musical meter') accounted for over 40% of the variance in single word reading in children with and without dyslexia (Huss et al., 2011). Performance in the musical task was most strongly associated with the auditory processing of rise time, even though beat structure was varied by manipulating the duration of the musical notes.

The study of urban and landscape history has recently questioned the peripheral condition of certain areas and re-examined them as valuable parts of an international network . In such a framework cities are not only recipients of foreign influences but active agents in their own urban transformations. Meanwhile, the regeneration of urban waterfronts appears increasingly in the spotlight globally , but the re-use of the waterfront as public space began more than a century ago.
Buenos Aires is an example of a ‘peripheral’ city, in which waterfront parks at the end of the nineteenth century were the product of international influences combined with local conditions, needs and expertise. Buenos Aires developed a continuous increase and diversity of leisure waterfront space, making it different from most European or ‘central’ cities. This paper will analyse the process of translation of landscape design on Buenos Aires’ waterfront while outlining the significance of waterfront parks to the city and its growing urban population.

Objective: Previous studies with patients diagnosed with Major Depressive Disorder (MDD) revealed deficits in working memory and executive functions. In the present study we investigated whether patients with MDD have the ability to allocate cognitive resources in dual task performance of a highly challenging cognitive task (working memory) and a task that is seemingly automatic in nature (postural control). Method: Fifteen young (18–35 years old) patients with MDD and 24 healthy age-matched controls performed a working memory task and two postural control tasks (standing on a stable or on a moving platform) both separately (single task) and concurrently (dual task). Results: Postural stability under single task conditions was similar in the two groups, and in line with earlier studies, MDD patients recalled fewer working memory items than controls. To equate working memory challenges for patients and controls, task difficulty (number of items presented) in dual task was individually adjusted such that accuracy of working memory performance was similar for the two groups under single task conditions. Patients showed greater postural instability in dual task performance on the stable platform, and more importantly when posture task difficulty increased (moving platform) they showed deficits in both working memory accuracy and postural stability compared with healthy controls. Conclusions: We interpret our results as evidence for executive control deficits in MDD patients that affect their task coordination. In multitasking, these deficits affect not only cognitive but also sensorimotor task performance.

This article examines the debate precipitated by the Thatcher government's (unsuccessful) attempt to secure a British boycott of the 1980 Moscow Olympics in response to the Soviet invasion of Afghanistan. Aware that it faced a struggle to win over the autonomous British Olympic Association, but with Thatcher in particular keen to support the United States, the government's case that the invasion required a specific response in the form of a boycott was steadily overshadowed as the public debate increasingly focused on arguments over human rights and détente and the use of state power.

Children of the revolution: parents, children and the revolutionary struggle in late imperial Russia
Resumo:
While there has been a considerable growth in scholarly interest in Russian child- hood and youth, the presence of children in the revolutionary movement has largely been overlooked. Studies of female revolutionaries have acknowledged that family concerns often had an impact on women’s party careers, but few have explored fully the relationship between mothers and their children. Similarly, “general” historical works on the Russian revolution have rarely engaged with questions about the family lives of the predominantly male party members. This article will assess how becoming a parent affected the careers of both male and female revolutionaries, as well as the ways in which familial concerns and the presence of children had an impact on the movement itself. It will highlight that children could have both positive and negative effects on the operations of the underground, at times disrupting activities, but at others proving to be useful decoys and helpers. Children’s attitudes to their parents’ revolutionary careers will also be examined, highlighting that while some children wished they had less politically active parents, others enthusiastically helped the movement. Though expanding the scholarly gaze on the Russian underground to take in the presence of children does not change the grand narrative of the revolution, it enriches our understanding considerably and offers a new insight into the daily struggles of the revolutionary movement.
