First Ramsey-type mass measurements with ISOLTRAP and design studies of the new PENTATRAP project

Der Einsatz von Penningfallen in der Massenspektrometrie hat zu einem einmaligen Genauigkeitssprung geführt. Dadurch wurden Massenwerte verschiedenster Atome zu wichtigen Eingangsparametern bei immer mehr physikalischen Fragestellungen. Die Massenspektrometrie mit Hilfe von Penningfallen basiert auf der Bestimmung der freien Zyklotronfrequenz eines Ions in einem homogenen Magnetfeld νc=qB/(2πm). Sie wird mit Flugzeitmethode (TOF-ICR) bestimmt, wobei eine relative Massenungenauigkeit δm/m von wenigen 10^-9 bei Nukliden mit Lebensdauern von <500 ms erreicht wird. Dies wurde durch die im Rahmen dieser Arbeit erstmals in der Penningfallen-Massenspektrometrie eingesetzten Ramsey-Methode möglich. Dabei werden zeitlich separierte, oszillierenden Feldern zur resonanten Ionenanregung genutzt, um die Frequenzmessung durch die Flugzeitmethode zu verbessern. Damit wurden am Penningfallenmassenspektrometer ISOLTRAP an ISOLDE/CERN die Massen der Nuklide 26,27Al und 38,39Ca bestimmt. Alle Massen wurden in die „Atomic Mass Evaluation“ eingebettet. Die Massenwerte von 26Al und 38Ca dienten insbesondere zu Tests des Standardmodells. Um mit Massenwerten fundamentale Symmetrien oder die Quantenelektrodynamik (QED) in extremen Feldern zu testen wurde ein neues Penningfallenprojekt (PENTATRAP) für hochpräzise Massenmessungen an hochgeladenen Ionen konzipiert. In dieser Doktorarbeit wurde vornehmlich die Entwicklung der Penningfallen betrieben. Eine Neuerung bei Penningfallenexperimenten ist dabei die permanente Beobachtung des Magnetfeldes B und seiner zeitlichen Fluktuationen durch so genannte „Monitorfallen“.

The elderly health status and its correlation with ageing biomarkers: the European Project Mark-Age

According to the latest statistics projections formulated by Eurostat, the proportion of elderly EU-27’s population aged over 65 years old is predicted to increase from 17.5 % in 2011 to 29.5 % by 2060. This "population explosion" makes extremely important to identify the different genetic and molecular mechanisms which underpin the morbidity and mortality along with new strategies able to counteract or slow down its progress. In this scenario fits the European Project MARK-AGE whose aim was to identify a robust set of biomarkers of human ageing able to discriminate between chronological and biological ageing and to derive a model for healthy ageing through the analysis of three populations from different European countries, supposed to be characterized by different ageing rate: 1. Subjects representing the “Normal” or “Physiological” aging. 2. Subjects representing the “successful” or “decelerate” aging 3. Subjects representing the “accelerated” aging. The aim of this work was to recruit and characterize volunteers, to perform an accurate analysis of the health status of elderly recruited subjects (60-79 years) verifying any possible dissimilarity in their aging trajectories, to identify a set of robust ageing biomarkers and investigate possible correlations between ageing biomarkers and health status of recruited volunteers. The model proposed by MARK-AGE Project regarding different ageing trajectories has been confirmed and several ageing biomarkers have been identified.

Developing European conservation and mitigation tools for pollination services: approaches of the STEP (Status and Trends of European Pollinators) project

Pollinating insects form a key component of European biodiversity, and provide a vital ecosystem service to crops and wild plants. There is growing evidence of declines in both wild and domesticated pollinators, and parallel declines in plants relying upon them. The STEP project (Status and Trends of European Pollinators, 2010-2015, www.step-project.net) is documenting critical elements in the nature and extent of these declines, examining key functional traits associated with pollination deficits, and developing a Red List for some European pollinator groups. Together these activities are laying the groundwork for future pollinator monitoring programmes. STEP is also assessing the relative importance of potential drivers of pollinator declines, including climate change, habitat loss and fragmentation, agrochemicals, pathogens, alien species, light pollution, and their interactions. We are measuring the ecological and economic impacts of declining pollinator services and floral resources, including effects on wild plant populations, crop production and human nutrition. STEP is reviewing existing and potential mitigation options, and providing novel tests of their effectiveness across Europe. Our work is building upon existing and newly developed datasets and models, complemented by spatially-replicated campaigns of field research to fill gaps in current knowledge. Findings are being integrated into a policy-relevant framework to create evidence-based decision support tools. STEP is establishing communication links to a wide range of stakeholders across Europe and beyond, including policy makers, beekeepers, farmers, academics and the general public. Taken together, the STEP research programme aims to improve our understanding of the nature, causes, consequences and potential mitigation of declines in pollination services at local, national, continental and global scales.

The Work and Workshop of the Master of the Rajhrad Altarpiece

The main aim of this project was to verify the possibility raised in the publication of new archival data in 1980 that the group of panel paintings attributed to the Master of the Rajhrad Altarpiece and his workshop were not created before 1420, as earlier academic opinion held, but in fact only around 1450. It included a detailed analysis of the 21 panels forming the group, including infrared reflectography research. This helped identify the highly personal underdrawing style of the "Rajhrad Master" as common to all the panels in the group, proving that they really form a coherent whole. Questions of the painter's education and the nature of Bohemian society around 1450 were also considered, as. Bartlova felt these had been neglected in earlier studies. She concludes that the Master studied in Prague in the late 1430s and then continued studying in Vienna and Munich from 1440. The new dating of the group of panels connected with this anonymous master and his workshop throws new light on Bohemian artistic production during the late Hussite period (c.1430-c.1470). It was generally thought that artistic activity moved out of Prague after the outbreak of the Hussite wars in the 1420s, but this research revealed considerable activity there throughout the period. Numerous painters listed in the Book of the Prague Painters' Guild for this period can now be linked with extant panels, although most of these have survived outside Prague, principally in South Bohemia. These findings have broad implications for studies of Bohemian art in this period.

Effect of implementing project-based education in high school physics : file folder bridge engineering

Project-based education and portfolio assessments are at the forefront of educational research. This research follows the implementation of a project-based unit in a high school physics class. Students played the role of an engineering firm who designed, built and tested file folder bridges. The purpose was to determine if projectbased learning could improve student attitude toward science and related careers like engineering. Teams of students presented their work in a portfolio for a final assessment of the process of designing, building and testing their bridges.

Uncovering poiesis : the role of production in technical communication, work, and public life

This dissertation is a report on a collaborative project between the Computer Science and the Humanities Departments to develop case studies that focus on issues of communication in the workplace, and the results of their use in the classroom. My argument is that case study teaching simulates real-world experience in a meaningful way, essentially developing a teachable way of developing phronesis, the reasoned capacity to act for the good in public. In addition, it can be read as a "how-to" guide for educators who may wish to construct their own case studies. To that end, I have included a discussion of the ethnographic methodologies employed, and how it was adapted to our more pragmatic ends. Finally, I present my overarching argument for a new appraisal of the concept of techné. This reappraisal emphasizes its productive activity, poiesis, rather than focusing on its knowledge as has been the case in the past. I propose that focusing on the telos, the end outside the production, contributes to the diminishment, if not complete foreclosure, of a rich concept of techné.

Europeanization Process in Italian Social Work Education

The article shows the process of Europeanization of the Italian social work education. After a brief excursus of the development of social work education in Italy, the paper presents the experiences made in the context of Socrates Erasmus project. Considering the results of the Thematic Network in Social Work organised by Parma University, some reflections are presented on the effects of Europeanization both respect the teachers and the students.

Work in Progress: Social Work, the State and Europe

Social work has had varying relationships with the nation state both over time and between different countries. From its early stages the occupation had both state sanctioned and voluntary streams. Its international dimension has been enhanced in the European context through policy and funding measures over the past few decades. During this period we have also seen the rise of globalising trends leading to questions about the ongoing powers of nation states. This paper examines some aspects of the relationship between social work and the state, taking into account the emergence of European and also international policies and frameworks. The paper focuses initially on migration as an example of a common trend; an area of policy with both national and European dimensions; and a field in which social professionals are engaged to varying degrees. Secondly, it considers the progress of the ‘professional project’ in Europe, using developments in five countries to illustrate some of the issues associated with ‘professionalization’. European and international frameworks may lead to some convergence in national understandings of the key roles of social workers and an enhanced sense of professional identity across nation states, despite very different starting points and current forms of organisation.

Policy Contexts of Social Work in Britain: the wider implications of 'New' Labour and the 'New Legal Regime'

Several commentators have expressed disappointment with New Labour's apparent adherence to the policy frameworks of the previous Conservative administrations. The employment orientation of its welfare programmes, the contradictory nature of the social exclusion initiatives, and the continuing obsession with public sector marketisation, inspections, audits, standards and so on, have all come under critical scrutiny (c.f., Blyth 2001; Jordan 2001; Orme 2001). This paper suggests that in order to understand the socio-economic and political contexts affecting social work we need to examine the relationship between New Labour's modernisation project and its insertion within an architecture of global governance. In particular, membership of the European Union (EU), International Monetary Fund (IMF) and World Trade Organisation (WTO) set the parameters for domestic policy in important ways. Whilst much has been written about the economic dimensions of 'globalisation' in relation to social work rather less has been noted about the ways in which domestic policy agenda are driven by multilateral governance objectives. This policy dimension is important in trying to respond to various changes affecting social work as a professional activity. What is possible, what is encouraged, how things might be done, is tightly bounded by the policy frameworks governing practice and affected by those governing the lives of service users. It is unhelpful to see policy formulation in purely national terms as the UK is inserted into a network governance structure, a regulatory framework where decisions are made by many countries and organisations and agencies. Together, they are producing a 'new legal regime', characterised by a marked neo-liberal policy agenda. This paper aims to demonstrate the relationship of New Labour's modernisation programme to these new forms of legality by examining two main policy areas and the welfare implications they are enmeshed in. The first is privatisation, and the second is social policy in the European Union. Examining these areas allows a demonstration of how much of the New Labour programme can be understood as a local implementation of a transnational strategy, how parts of that strategy produce much of the social exclusion it purports to address, and how social welfare, and particularly social work, are noticeable by their absence within policy discourses of the strategy. The paper details how the privatisation programme is considered to be a crucial vehicle for the further development of a transnational political-economy, where capital accumulation has been redefined as 'welfare'. In this development, frameworks, codes and standards are central, and the final section of the paper examines how the modernisation strategy of the European Union depends upon social policy marked by an employment orientation and risk rationality, aimed at reconfiguring citizen identities.The strategy is governed through an 'open mode of coordination', in which codes, standards, benchmarks and so on play an important role. The paper considers the modernisation strategy and new legality within which it is embedded as dependent upon social policy as a technology of liberal governance, one demonstrating a new rationality in comparison to that governing post-Second World War welfare, and which aims to reconfigure institutional infrastructure and citizen identity.

Organisational and methodical aspects of drug and addiction prevention among young people. Developments in the Ukraine, in Germany, Spain and Russia (Project Description)

From october 2000 to march 2003 the project has been coordinated by the institute of social work and welfare studies of the TU Dresden and financed by the European Commission (INCO-COPERNICUS-Programme). It was an international cooperation between the TU Dresden (Germany), the University of Internal Affairs and the National Technical University in Kharkiv (Ukraine), the research institute AREA in Valenciá (Spain) and the Belgorod Juridical Institute of the Ministry of Internal Affairs (Russia) which was established for improving the knowledge base of drug prevention activities by the East European partners. The overall aim of the project was the analysis and elaboration of approaches to drug and addiction prevention. Under consideration of the specific conditions within the East-European countries this work should contribute to the development of pluralistic approaches towards health promotion which are embedded into an intercultural, European horizon.

Making research works visible and stimulating a research milieu in the field of social work - The European Resource Centre for Social Work Research (CERTS)

The project to create a European Resource Centre for Social Work Research (CERTS) has been agreed in December 2001 by the General Research Board of the European Commission within the framework programme 'Accompanying Measures for the improving the Human research potential and the Socio Economic Knowledge Base'.

Youth and Health as an issue of Research in Social Work - Two examples of current Research

Health issues under aspects pertaining to social work are currently being investigated in our department under two main perspectives. The study of Youth, Health, and Internet is based on experiences with a project of e-mail counseling for youths we have been running in our department for one year so far. Our thesis is that the internet has become an important platform for youngsters in general as well as concerning health issues specifically. So far, however, little is known about the ways youths address their health related problems in the net. We believe that research in this area is badly needed since future concepts of effective health improvement and prevention for youths cannot ignore this medium. Biography and Health is our second focus of investigation, addressing deficiencies in the empirical research of Aaron Antonovsky´s salutogenetic concept that has lately become quite popular in many health discussions. Drawing from biographical methods we are currently investigating the development of the so called "sense of coherence" - the center piece of salutogenesis.

Youth Work and Schools in ‘Full-day’ education systems: International Comparison of Links between Formal and Non-formal Education

In this article I will outline the methodological approach of a non-empirical comparative research project which I began in 2003. The project is situated in the context of the research training group “Youth Welfare in Transition” at the universities of Bielefeld and Dortmund, funded by the German Research Council (Deutsche Forschungsgemeinschaft). In that context I have organised an international conference about the modes of cooperation between school and youth work agencies with colleagues from Canada, France, Finland, Italy, Japan, the Netherlands, Russia, Switzerland, the United Kingdom, the United States, Israel, and Germany. Meeting in Bielefeld from the 9th to the 11th of October 2003, we compared the respective national arrangements of formal and non-formal education (www.uni-bielefeld.de/paedagogik/agn/ag8/Ganztagsbildung.html). This note is based on the scheme of comparison which was given to the contributors in order to help them preparing their presentations. At the moment the scheme is nearing completed with significant data prepared by the contributors/authors (see Otto/Coelen 2004), supplemented with data from research works published in German and English. The next step will be to set up an empirical project about the relationships between schools and youth work agencies in three European countries (probably France, Finland and the Netherlands).

Collaborating or Colluding: A Practice Research Project with Ex-Offenders and their Families in Singapore

Working with the family members of ex-offenders is a daunting and newly developing aspect of offender rehabilitation in Singapore. A small scale practice research project was carried out by three social work practitioners and two academics over a period of 22 months, with the aim to explore the pertinent issues and challenges in working with family members of ex-offenders. Systematic documentation of the process of working with three cases was carried out. Specific skills and strategies were suggested, and recommendations for changes to service delivery and policy for working with ex-offenders and family members were made to the authorities. This article highlights the enriching journey of collaboration between the academics and practitioners.
