The expansion of populations of invasive species continues to compromise the ecological and economic integrity of our natural resources. The negative effects of invasive species on native biota are widely reported. However, less is known about how the duration (i.e., age of oldest invaders) and intensity (i.e., density and percent cover) of an invasion influences native plant diversity and abundance at the microsite scale. We examined the influence of density, percent cover, and age of Amur honeysuckle (a nonnative invasive shrub), and several environmental factors on native plant taxa at 12 mixed hardwood forests in Indiana, USA. Overall, study sites with the greatest taxonomic diversity (Shannon's Diversity; H′), richness (S), percent cover, and density of native vegetation also had the lowest percent cover of Amur honeysuckle in the upper vertical stratum (1.01 to 5 m). Based on linear mixed model analyses, percent cover of Amur honeysuckle in the upper vertical stratum was consistently and negatively correlated with H′, S, total percent cover, and woody seedling density of native taxa at the microsite scale (P < 0.05). Duration of Amur honeysuckle at the microsite scale was not significant when percent cover of Amur honeysuckle in the upper vertical stratum was included in models. However, duration of Amur honeysuckle invasion was significantly correlated with dependent variables and with upper-stratum honeysuckle cover, suggesting that older Amur honeysuckle in a microsite resulted in greater light competition from above for native understory plant species. Beyond increased cover and shading, our results do not provide evidence of duration-related effects from long-term dominance of honeysuckle in our sampled mixed hardwood forest sites.
Crisis presents chances for change and creativity: Adorno's famous dictum that writing poetry after Auschwitz would be barbaric has haunted discourse on poetics, but has also given rise to poetic and theoretical acts of resistance. The essays in this volume discuss postwar poetics in terms of new poetological directions and territory rather than merely destruction of traditions. Embedded in the discourse triggered by Adorno, the volume's foci include the work of Paul Celan, Gottfried Benn, and Ingeborg Bachmann. Other German writers discussed are Ilse Aichinger, Rose Ausländer, Charlotte Beradt, Thomas Kling, Heiner Müller, and Nelly Sachs; concrete poetry is also treated. The final section offers comparative views of the poetics of European literary figures such as Jean Paul Sartre, André Malraux, and Danilo Kis and a consideration of the aesthetics of Claude Lanzmann's film 'Shoah.'

To report trends in underweight, overweight and obesity in 12–15-year-old adolescents and examine changes in dieting behaviour, which have been less well documented.
Design
Comparison of two independent representative cross-sectional surveys.
Setting
Northern Ireland.
Subjects
Weight and height were objectively measured in 1324 boys and 1160 girls in 1996 and 1274 boys and 1374 girls in 2007. Participants reported whether they were following any particular diet including a self-proposed or prescribed weight-reduction diet.
Results
Overweight and obesity increased in girls from 15 % to 23 % and 2 % to 6 %, respectively. Increases were more modest in boys with overweight increasing from 13 % to 18 % and obesity from 3 % to 6 %. The proportion of underweight adolescents decreased from 9 % to 6 % in girls and 8 % to 5 % in boys. Evidence of social disparity was observed in girls from a manual socio-economic background, with overweight/obesity prevalence rates increasing from 21 % to 36 % compared with 15 % to 26 % in girls from a non-manual background. Despite these trends fewer adolescents, in particular girls, reported following weight-reduction diets (14 % of overweight/obese girls in 2007 v. 21 % in 1996; 8 % of boys in 2007 v. 13 % in 1996). Of these girls, the proportion from a manual background following weight-reduction diets decreased from 25 % to 11 %.
Conclusions
Overweight and obesity are continuing to increase in adolescents despite government and media awareness strategies. There also appears to be reduced dieting behaviour, despite increasing body weight, particularly in girls from manual socio-economic backgrounds.
In this sixty-fifth anniversary year of the end of the Second World War and the liberation of Auschwitz, we are fast approaching the eightdecade death-knell for all “lebendige Erinnerung” (living, or communicative, memory) of the Nazi genocide. It would seem, then, that we have reached another critical milestone on our path backward into the future. As the last witnesses, survivors, and perpetrators pass out of real time, the imperative of Holocaust remembrance and attendant conundrum of how to express that re-presented past, seems to be entering a new and particularly perilous phase, one that will soon be exclusively characterized by “post-memory,” to borrow Marianne Hirsch's term. The idea of a dawning age of post-remembrance is associated for many with a terrible sense of urgency, fueled by the idea that such a transition may take us a step nearer to a coming time of complete erasure. The act of remembrance is now engaged in a “race against time,” requiring such massive interventions as, for example, the Survivors of the Holocaust Visual History Foundation, which aims to record and archive on film and in aeternum the memories of all remaining Holocaust survivors. So, nearly seven decades after the “break” of 1945, another major sense of caesura has come upon us, arguably even more radical than that first Zero Hour. With this sense of an impending end comes the sense that returns, recall, and representations are needed now more than ever.
This chapter has four interrelated objectives. One objective is to provide an overview and evaluation of the many studies published during the last 20 years in which experienced auditors formed judgments or made decisions while performing audit tasks. The second objective is to recommend issues for and approaches to future research. A third objective is to compare findings of the audit judgment/decision–making (J/DM) studies with nonaudit J/DM studies, thereby increasing nonaudit J/DM researchers' awareness of these audit studies. The fourth objective is to provide a common foundation for Chapter 7 by Libby on knowledge and memory in auditing and Chapter 8 by Messier on audit decision aids. Meeting these objectives, as discussed later, should enhance the accessibility of audit J/DM research findings, highlight boundary conditions of extant theories, focus future research on promising issues, identify profitable methods for future research, and stimulate J/DM theory construction and revision.
The remainder of this chapter is divided into seven sections. The next section defines auditing and the following one highlights the objectives of J/DM research in the audit context. In these sections it is noted that the audit J/DM studies we review have primarily sought to: (a) describe how and how well auditors make judgments and decisions, (b) prescribe how to improve audit J/DM, and (c) contribute to nonaudit J/DM knowledge. In addition, it is noted that the totality of audit tasks/contexts features make auditing both distinctive and a rich arena for developing and testing J/DM theories.
