description: In fast allen modernen Gesellschaften ist Alkoholabhängigkeit die verbreitetste Suchterkrankung. Gegenwärtig leben rund 2,5 Millionen Alkoholabhängige im Gebiet der Bundesrepublik Deutschland, viele davon haben Kinder. Aktuelle Schätzungen gehen davon aus, daß rund zwei Millionen minderjährige Kinder in Familien mit alkoholabhängigen Elternteilen leben. Hinzu kommen weitere 5 - 6 Millionen Menschen, die als erwachsene Kinder aus suchtbelasteten Familien durch eine erhöhte Vulnerabilität gegenüber psychischen Störungen besonders gefährdet sind (Klein 1998, S. 8 - 9). Während für erwachsene Alkoholabhängige inzwischen ein breitgefächertes Netz unterschiedlicher Hilfeeinrichtungen im Rahmen der Suchtkrankenhilfe existiert, ist die Situation der Kinder aus diesen Familien in Deutschland lange Zeit kaum berücksichtigt worden, obwohl diese Kinder mittlerweile als anerkannte Risikogruppe eingestuft werden. In den neunziger Jahren hat sich diese Situation allmählich verändert, ohne daß Betreuungsnachfrage und Betreuungsangebot bisher in ein ausgewogenes Verhältnis zueinander gebracht werden konnten. 1995 verfügten lediglich 12% der Beratungsangebote in der ambulanten Suchtkrankenhilfe über spezielle Angebote für Minderjährige (Mayer 1998, S. 3). Bezeichnend für die schwache Verankerung solcher speziell an Kinder gerichteter Angebote in der Suchtk rankenhilfe ist, daß sie sich zumeist noch im Stadium eines zeitlich befristeten Modellprojekts befinden.

Implizit-explizit-Moderation : fungieren funktional äquivalente Situations- und Personenmerkmale der Introspektion und der Adjustierung als Konsistenzmoderatoren?

description: Da implizite und explizite Dispositionsindikatoren in der Regel nur mäßig miteinander korrelieren, stellt sich die Frage nach potentiellen Konsistenzmoderatoren. Insbesondere zwei Prozesse kommen in Frage: Personen haben aufgrund mangelnden introspektiven Zugangs Schwierigkeiten mit dem direkten Abruf von Einstellungen bzw. Persönlichkeitseigenschaften und/oder Menschen neigen zur Adjustierung ihrer Selbstauskünfte an soziale und personale Standards. Die Bestätigung solcher theoretisch begründeten Moderatorhypothesen ist überzeugender, wenn sie mit funktional äquivalenten Situations- und Persönlichkeitsmerkmalen gleichzeitig gelingt. Die Konsistenz zwischen impliziten und expliziten Dispositionsindikatoren sollte nicht nur mit der individuellen Selbstkenntnis und Aufrichtigkeit variieren, sondern in gleichsinniger Weise auch über Situationen, die in unterschiedlichem Maße zu Dispositionsabruf und Adjustierung anregen. Zudem kann geprüft werden, wie personale und situative Moderatorvariablen zusammenwirken. Diese Arbeit verbindet somit den Moderatorvariablenansatz mit dem Modernen Interaktionismus, indem Person × Situation-Interaktionen auf Moderatorebene getestet werden. Die Hypothesen wurden am Beispiel der Einstellung Deutscher (N = 104) gegenüber Türken untersucht. Die Einstellung wurde anhand des Impliziten Assoziationstests (IAT) und expliziten Eigenschafts- und Vorurteilsskalen erfasst. Als personale Konsistenzmoderatoren wurden private und öffentliche Selbstaufmerksamkeit, Motivation zur Vorurteilskontrolle sowie Einstellungswissen erhoben. Zur situativen Manipulation wurden die Bereitschaft zur Introspektion und die Anonymität der Untersuchungssituation variiert. Bei der separaten Betrachtung der Situations- bzw. Persönlichkeitsmerkmale finden sich hypothesenkonforme Moderatoreffekte der privaten Selbstaufmerksamkeit. Zudem zeigt sich eine synergetische Moderation, wenn private Selbstaufmerksamkeit und Bereitschaft zur Introspektion gemeinsam berücksichtigt werden. Die Ergebnisse werden hinsichtlich der Validität des IAT und des Zusammenhanges zwischen impliziten und expliziten Repräsentationen diskutiert.

description: Das Massenphänomen "Techno" und der damit oftmals einhergehende Drogenkonsum gehen mittlerweile in das ungefähr 16. Jahr in Deutschland. Die Aufteilung der anfangs noch recht homogenen Techno-Szene und ihrer Anhänger in fast unzählige kleinere Szenen, die sich teilweise nur graduell unterscheiden, hat für eine große Unübersichtlichkeit gesorgt. Kleinere Szenen finden kaum Erwähnung in der entsprechenden Literatur, während über die Techno-Szene an sich bereits viele Arbeiten veröffentlicht wurden. Die vorliegende Arbeit beschäftigt sich mit einer der oben erwähnten kleineren Szenen, nämlich der Goa-Partyszene. Diese Szene, die nach dem Bundesstaat in Indien benannt ist, hat seit ca. Anfang der 90er Jahre mehr und mehr Anhänger dazu gewonnen, nicht nur in Deutschland, sondern auch in vielen Ländern der Welt. Reliable Zahlen liegen aufgrund des bislang Nichtvorhandenseins spezifischer Studien / Untersuchungen leider nicht vor. Der Konsum psychotroper Substanzen ist allerdings in der Goa-Szene wie auch in der Techno-Szene weit verbreitet, was u.a. durch die Angaben der Interview-Partner bestätigt wird. Im Rahmen dieser Ausarbeitung wird zunächst einmal auf die Thematik hingeführt: Nach einer Beschreibung der Anfänge der Techno-Szene sowie der darauf folgenden Aufsplittung in viele kleinere Szenen wird die Goa-Szene sowie deren eigene Entwicklung beschrieben. Anschließend wird über die in dieser Szene bevorzugt konsumierten psychotropen Substanzen informiert, da man den Goa-Partybesuch kaum von der Einnahme von Drogen trennen kann. Daraufhin folgen theoretische Vorüberlegungen unter den Gesichtspunkten der qualitativen Sozialforschung, woraufhin schließlich der Aufbau der vorliegenden Studie erläutert wird. Anschließend werden die durch die Verwendung qualitativer Interviews gewonnenen Ergebnisse beschrieben, zusammengefasst und im Kapitel 8 und 9 abschließend diskutiert.

description: Whittaker, Holmes, Del Valle, and James are to be commended for this latest scholarly effort that builds from more than a decade of focus group consultations with established experts, and publication of core debates operating in the field whenever residential care is considered. The editors have been careful to narrow the focus of their efforts to Anglo-American exemplars (England, Scotland, Canada, USA, and Ireland) and Continental European exemplars of planful uses of residential group living with young people (Spain, Netherlands, Germany, Denmark, Italy, Portugal, Finland, and France). Exemplars were also provided for illustrative purposes from Argentina, Australia, and Israel, even though this latter example – which includes early military training for nearly two-thirds of the youthful population – is not illustrative of residential care operating in the Middle East. Residential care and education in contemporary Israel is closely aligned with Anglo-American exemplars, with boarding schools closely aligned with Continental European exemplars.

description: Our society faces numerous challenges that emerged at the turn of the millennium. In the wake of the 2007 financial crisis, reducing inequality and poverty has become a pressing issue not only in the Global South but also in Europe. Another significant challenge that emerged before the turn of the millennium but has since gained even greater importance is addressing climate change. Furthermore, the global urban population is increasing at an unprecedented rate, highlighting the importance of urban planning in creating safe, livable, and prosperous cities. The dissertation addresses these issues by empirically analyzing the drivers of these phenomena. The first article examines how long-term poverty has developed in 26 European countries after the financial crises and by what macro-level factors it is driven. The findings suggest that the long-term poverty rate stayed unchanged in 13 out of 26 European countries. GDP does not affect long-term poverty rates, but male employment rates and social welfare expenditure are negatively associated. The second article provides an overview of the development of environmental concern in 29 countries responsible for 71% of global CO₂ emissions over the past three decades. Moreover, the article examines the determinants of environmental concern at the individual level and country level. Compared to the previous measurement in 2010, environmental concern has increased in nearly all countries. Education, post-materialistic values, political attitudes, and trust in the news media and science are the main driving factors of environmental concern at the individual level. At the country level, environmental concern is predominately influenced by countries’ GPD. The third article sheds light on the relationship between urban greenery, mixed land use and life satisfaction in Switzerland. Only older residents tend to benefit from a greener neighborhood. This relationship is mainly driven by trees and grass located in gardens and parks. In contrast, land use mixture is only positively associated with younger residents’ life satisfaction, and the positive effect diminishes at higher ages.

Wie erleben Kinder die Suchterkrankung ihrer Eltern? Eine qualitative Studie mit Briefen von Kindern an ihre Eltern

description: "An meinen Vater... Als ich vom nassen Brief hörte, dachte ich nur, daß ich auch schreiben wollte, schreiben wollte was mir schon seit Jahren am Herzen liegt. In der Kindheit bemerkte ich deine Sucht nicht, und du warst für mich der perfekte Vater. Bis ich anfing nachzudenken. Immer öfters hörte ich dich und Mutter streiten, glaubte es sei meine Schuld und hatte den Wunsch zu sterben um für das zu büßen was zwischen Euch schief lief...(...) Dann begriff ich, erstmals warum das alles passierte. Vater ist alkoholsüchtig... Kann er dafür, weiß er was er Mutter antut und angetan hat? Ich wußte es nicht und haßte dich dafür daß du Mutter zum Weinen brachtest..." (s. Brief 9, Anhang) Dies ist der Anfang eines Briefes, in dem ein Kind sein Erleben der Sucht des Vaters schildert. Dieser Brief soll im Verlauf dieser Diplomarbeit analysiert werden, sowie 12 weitere Briefe (s. Anhang). In dieser Studie sind alle betroffenen Eltern alkoholabhängig. Es ist inzwischen in Fachkreisen allgemein bekannt, daß nicht nur der Alkoholabhängige unter der Abhängigkeit leidet, sondern die ganze Familie von den Auswirkungen der Abhängigkeit betroffen ist (vgl. Arenz-Greiving 1998, Wegscheider 1988, Zobel 2000). Während eines Praktikums in einer Blaukreuz-Beratungsstelle und auch beim Schreiben meines Praktikumsberichts habe ich mich mit diesem Thema intensiv beschäftigt, und auch jetzt bewegt mich dieses Thema immer noch sehr. Diese Problematik, die sehr drastisch sein kann, weckte eine tiefe emotionale Betroffenheit in mir, obwohl ich von meinem sozialen Umfeld her kaum damit konfroniert worden bin. Bei meiner Literatursuche fiel mir auf, daß in Untersuchungen meist erwachsene Kinder alkoholkranker Eltern retrospektiv die Alkoholkrankheit ihrer Eltern Wie erleben Kinder die Suchterkrankung ihrer Eltern? Seite 2 und das von ihnen erlebte Familienleben schilderten (vgl. Walch-Heiden 1990, Zobel 2000) bzw. Gruppenleiter über ihre pädagogische oder therapeutische Arbeit mit Gruppen von Kindern suchtkranker Eltern berichteten (vgl. Mayer 2000, Wunsch & Wollmann 1998). Selten kommen die betroffenen Kinder selbst zu Wort (z.B. Kinderzeichnungen in Black 1988). Dabei könnten sie, wenn das Schweigen über den Alkoholismus gebrochen ist, doch besonders lebensnah darüber berichten. Deshalb freue ich mich sehr, in dieser Diplomarbeit zumindest teilweise prospektiv darüber schreiben zu können (einige Kinder sind bereits volljährig bzw. ausgezogen), wie Kinder die Suchterkrankung ihrer Eltern erleben. Ich wünsche meinen Lesern viel Anregung beim Lesen und hoffe, das Erleben dieser Kinder in ihren Familien ein wenig mehr beleuchten zu können.

“As public scientists, we express dismay and sadness at having suffered unjustified destruction, a result of obscurantism and anti-scientific knee-jerk reactions.”

 

Giuseppe Verdi (1813–1901), the prolific composer of Italian opera, frequently explored themes of destruction in his works. His 28 operas often delve into the profound emotional and physical devastations experienced by his characters. Verdi’s focus on devastation came to mind in the last few days as vandals, presumably anti-technology protesters, destroyed Italy’s first field trial of gene-edited (GE) crops on the night of June 21, 2024. Launched on May 18 by our collaborators at the University of Milan, this trial was meant to pave the way for sustainable agriculture. “Distrutto il campo sperimentale di riso RIS8imo,” said the headline. Destroyed!

“Come scienziati pubblici esprimiamo sconcerto e tristezza per aver subito una violenza ingiustificata, frutto di oscurantismo e pulsioni antiscientifiche.”

Giuseppe Verdi (1813–1901), grande compositore italiano, esplorava frequentemente il tema della distruzione nelle sue opere. Le sue 28 opere spesso approfondiscono profonde distruzioni spirituali e fische vissute dai suoi personaggi. Il focus di Verdi sulla devastazione mi è venuto in mente negli ultimi giorni, quando vandali, presumibilmente vandali anti- tecnologia, hanno distrutto la prima sperimentazione in campo di colture modificate geneticamente (GE) in Italia, nella notte del 21 giugno 2024. Lanciata il 18 maggio dai nostri collaboratori dell’Università di Milano, questa sperimentazione doveva aprire la strada all’agricoltura sostenibile. “Distrutto il campo sperimentale di riso RIS8imo,” diceva il titolo. Distrutto!

description: Synthetic biology aims at designing modular genetic circuits that can be assembled according to the desired function. When embedded in a cell, a circuit module becomes a small subnetwork within a larger environmental network, and its dynamics is therefore affected by potentially unknown interactions with the environment. It is well-known that the presence of the environment not only causes extrinsic noise but also memory effects, which means that the dynamics of the subnetwork is affected by its past states via a memory function that is characteristic of the environment. We study several generic scenarios for the coupling between a small module and a larger environment, with the environment consisting of a chain of mono-molecular reactions. By mapping the dynamics of this coupled system onto random walks, we are able to give exact analytical expressions for the arising memory functions. Hence, our results give insights into the possible types of memory functions and thereby help to better predict subnetwork dynamics.

Development and Evaluation of Transparent, Aligned Polycrystalline Alumina as an Infrared Window Candidate for Hypersonic Flight

description: Hypersonic flight is the key to unlocking a nation’s strategic advantage in this century’s military theater. Military powerhouses such as the United States, Russia, India, China, Australia, and the EU publicly possess hypersonic weapons capabilities. Such technology enables intercontinental travel orders of magnitude faster than conventional flights. A trip halfway across the world would take not twenty hours, but two. However, the level of thermal and chemical load the aircraft and these electronic equipment experience while at such high speeds cause them to fail. Thus, ceramic window materials are used to act as a barrier between the hypersonic flight environment and this sensitive electronic equipment. Such materials need to be both mechanically robust, but transparent within the relevant infrared ranges used for target detection. Single-crystal sapphire (alumina) is an infrared window material readily available, plentiful, and easy to microstructurally control and manufacture, but not optimal. Its transparency range is limited to the optical and near-infrared, while it exhibits poor mechanical and dielectric strength. Polycrystalline alumina (PCA) has recently been shown to possess more favorable infrared window characteristics as opposed to its single-crystal counterpart. This is achieved by processing using a platelet powder morphology in a single processing step – hot-pressing. Full densification (> 99.5%) of PCA samples was achieved, demonstrating maximum of 84% optical transparency, but accompanied by grain growth (60+µm), resulting in lower mechanical strength. This research thus works on a two-fold approach to minimizing the grain growth of PCA. Optical tests demonstrated favorable results for lowering isothermal temperatures to reduce grain growth. Weibull values of m = 28.8 and m = 9.7 from 4 point-flexure tests were obtained (ASTM 1161a). Thermal loading via ablation testing compared PCA samples to industry alternatives (single-crystal sapphire) and (equiaxed alumina). Ablation tests revealed the benefit of polycrystalline alumina over sapphire. The benefit of lower isothermal sintering temperatures for reduced grain growth resulted in higher peak load before failure, resulting in greater characteristic strength and minimal transmission lost during a minute of oxyacetylene heat flux exposure. Finally, additional work was done on nanoceramic MgO-Y2O3, in a ceramic-processing method like that of PCA. These findings will also be discussed.
Imagine a world without flowers

We owe it to insects. We really do. Without insects, we would have no colorful flowers. Imagine how drab the world would be without flowers.

 

Flowers are the spectacular result of coevolution between plants and insects. When flowers evolved in plants around 130 million years ago, they took advantage of insects to help them pollinate each other, therefore promoting sexual reproduction and enhancing resilience to environmental changes and diseases.

The intricate dance between plants and their insect pollinators is one of nature’s most fascinating stories. Flowers evolved bright colors, enticing scents, and sweet nectar to attract insects, while insects, in turn, evolved specialized structures and behaviors to access these rewards and transfer pollen from flower to flower. This mutualistic relationship — plants get insects to transfer pollen between flowers and insects get rewarded with food— has driven an incredible diversification of both plants and insects, filling our world with an astounding array of forms and functions.
