The Active Subjects of Welfare Reform: a Street-Level Comparison of Employment Services in Australia and Denmark

This paper explores the similarities and differences between Denmark and Australia in adopting welfare reform activation measures in the field of employment services. In Australia and Denmark the discourse of welfare reform centres the 'activation' of citizens through 'mutual obligation' type requirements. Through various forms of case management, unemployed individuals are encouraged to act upon themselves in creating the right set of ethical dispositions congruent with 'active citizenship'. At the same time any resistance to heightened conditionality on the part of the unemployed person is dealt with through a range of coercive and disciplinary techniques. A comparative case study between these two countries allows us to consider how similar ideas, discourse and principles are shaping policy implementation in countries that have very different welfare state trajectories and institutional arrangements for the delivery of social welfare generally and employment services specifically. And in research terms, a comparison between a Nordic welfare state and an Anglo-Saxon welfare state provides an opportunity to critically examine the utility of 'welfare regime' type analyses and the neo-liberal convergence thesis in comparative welfare research. On the basis of empirical analysis, the article concludes that a single focus on abstract typologies or political ideologies is not very helpful in getting the measure of welfare reform (or any other major policy development for that matter). At the 'street-level' of policy practice there is considerably more ambiguity, incoherence and contradiction than is suggested by linear accounts of welfare reform.

The Role of a Non-Governmental Organization in the Improvement of Employment in Finland: A Case Study

This study discusses one Non-Governmental Organization (NGO) as an alternative institution for the improvement of employment in a Finnish city. Empirical data was collected from 16 employees and from an official of the organization using questionnaires, interviews and participant observation. The data was analyzed qualitatively and the findings revealed that, the organization plays complementary role in cooperating with the government to provide social services to underprivileged groups of people, through which the organization is able to create jobs for long-term unemployed people in the city of Jyväskylä. However, the skill development training of the organization was found to be inadequate for boosting the employability of their employees in the open labour market, once the latter’s 1-2 year contract ended. The study concluded that for the organization to become a viable alternative institution for the improvement of employment in the city of Jyväskylä, it must improve the skill development training of their employees, as well as increase collaboration with other actors that are working towards the same goals.

Use of diagnostic microarrays for determination of virulence gene patterns of Escherichia coli K1, a major cause of neonatal meningitis

Forty Escherichia coli strains isolated primarily from neonatal meningitis, urinary tract infections and feces were screened for the presence of virulence genes with a newly developed microarray on the array tube format. A total of 32 gene probes specific for extraintestinal as well as intestinal E. coli pathotypes were included. Eighty-eight percent of the analyzed strains were positive for the K1-specific probe on the microarray and could be confirmed with a specific antiserum against the K1 capsular polysaccharide. The gene for the hemin receptor ChuA was predominantly found in 95% of strains. Other virulence genes associated with K1 and related strains were P, S, and F1C fimbriae specific for extraintestinal E. coli, the genes for aerobactin, the alpha-hemolysin and the cytotoxic necrotizing factor. In two strains, the O157-specific catalase gene and the gene for the low-molecular-weight heat-stable toxin AstA were detected, respectively. A total of 19 different virulence gene patterns were observed. No correlation was observed between specific virulence gene patterns and a clinical outcome. The data indicate that virulence genes typical of extraintestinal E. coli are predominantly present in K1 strains. Nevertheless, some of them can carry virulence genes known to be characteristic of intestinal E. coli. The distribution and combination of virulence genes show that K1 isolates constitute a heterogeneous group of E. coli.

Prescription patterns of antimicrobials in veterinary practices in Switzerland

OBJECTIVES The objective of this study was to analyse antimicrobial prescriptions by veterinarians and to evaluate the appropriateness of use compared with prudent use guidelines. PRACTICES AND METHODS: Computerized records of prescriptions and treatments from eight mixed veterinary practices were analysed over a period of 2 years. A total of 61 212 antimicrobial treatments were recorded. Treatments were classified according to animal species treated, indication for treatment, route of administration and antimicrobial class used. For each treatment and antimicrobial substance, the prescribed dose was calculated. Dosage, antimicrobial classes and combinations of different classes used for different indications were compared with published recommendations. RESULTS From the total amount of 1590 kg of active antimicrobial substance, sulphonamides (594 kg), tetracyclines (335 kg), and penicillins and cephalosporins (290 kg) were the classes of which the largest quantity was prescribed. Penicillins and cephalosporins were most frequently prescribed (37% of treatments), followed by aminoglycosides (18%), tetracyclines (14%) and sulphonamides (11%). Sixty-one per cent of the amount of antimicrobials prescribed was used for the treatment of groups of animals via feed or water. Antimicrobial classes classified as highest priority for human medicine by an international group of experts were used in 9% of the prescriptions. The dosage corresponded to the manufacturer's recommendation in 45% of the analysed prescriptions. CONCLUSIONS Most prescriptions corresponded well to guidelines on prudent use of antimicrobials. Nevertheless, the large variation of prescriptions among different veterinarians indicates that the usage of critical antimicrobial substances and the amount of antimicrobials used for group medication without a specific indication could be further reduced.

Patterns of exposure to infectious diseases and social contacts in early life and risk of brain tumours in children and adolescents: an International Case-Control Study (CEFALO)

BACKGROUND Infectious diseases and social contacts in early life have been proposed to modulate brain tumour risk during late childhood and adolescence. METHODS CEFALO is an interview-based case-control study in Denmark, Norway, Sweden and Switzerland, including children and adolescents aged 7-19 years with primary intracranial brain tumours diagnosed between 2004 and 2008 and matched population controls. RESULTS The study included 352 cases (participation rate: 83%) and 646 controls (71%). There was no association with various measures of social contacts: daycare attendance, number of childhours at daycare, attending baby groups, birth order or living with other children. Cases of glioma and embryonal tumours had more frequent sick days with infections in the first 6 years of life compared with controls. In 7-19 year olds with 4+ monthly sick day, the respective odds ratios were 2.93 (95% confidence interval: 1.57-5.50) and 4.21 (95% confidence interval: 1.24-14.30). INTERPRETATION There was little support for the hypothesis that social contacts influence childhood and adolescent brain tumour risk. The association between reported sick days due to infections and risk of glioma and embryonal tumour may reflect involvement of immune functions, recall bias or inverse causality and deserve further attention.

Dynamic patterns of ventricular remodeling and apoptosis in hearts unloaded by heterotopic transplantation

BACKGROUND Mechanical unloading of failing hearts can trigger functional recovery but results in progressive atrophy and possibly detrimental adaptation. In an unbiased approach, we examined the dynamic effects of unloading duration on molecular markers indicative of myocardial damage, hypothesizing that potential recovery may be improved by optimized unloading time. METHODS Heterotopically transplanted normal rat hearts were harvested at 3, 8, 15, 30, and 60 days. Forty-seven genes were analyzed using TaqMan-based microarray, Western blot, and immunohistochemistry. RESULTS In parallel with marked atrophy (22% to 64% volume loss at 3 respectively 60 days), expression of myosin heavy-chain isoforms (MHC-α/-β) was characteristically switched in a time-dependent manner. Genes involved in tissue remodeling (FGF-2, CTGF, TGFb, IGF-1) were increasingly upregulated with duration of unloading. A distinct pattern was observed for genes involved in generation of contractile force; an indiscriminate early downregulation was followed by a new steady-state below normal. For pro-apoptotic transcripts bax, bnip-3, and cCasp-6 and -9 mRNA levels demonstrated a slight increase up to 30 days unloading with pronunciation at 60 days. Findings regarding cell death were confirmed on the protein level. Proteasome activity indicated early increase of protein degradation but decreased below baseline in unloaded hearts at 60 days. CONCLUSIONS We identified incrementally increased apoptosis after myocardial unloading of the normal rat heart, which is exacerbated at late time points (60 days) and inversely related to loss of myocardial mass. Our findings suggest an irreversible detrimental effect of long-term unloading on myocardium that may be precluded by partial reloading and amenable to molecular therapeutic intervention.

Repeated and predictable patterns of ecotypic differentiation during a biological invasion: lake-stream divergence in parapatric Swiss stickleback

The relative importance of ecological selection and geographical isolation in promoting and constraining genetic and phenotypic differentiation among populations is not always obvious. Interacting with divergent selection, restricted opportunity for gene flow may in some cases be as much a cause as a consequence of adaptation, with the latter being a hallmark of ecologi- cal speciation. Ecological speciation is well studied in parts of the native range of the three-spined stickleback. Here, we study this process in a recently invaded part of its range. Switzerland was colonized within the past 140 years from at least three different colonization events involving differ- ent stickleback lineages. They now occupy diverse habitats, ranging from small streams to the pelagic zone of large lakes. We use replicated systems of parapatric lake and stream populations, some of which trace their origins to different invasive lineages, to ask (i) whether phenotypic divergence occurred among populations inhabiting distinct habitats, (ii) whether trajec- tories of phenotypic divergence follow predictable parallel patterns and (iii) whether gene flow constrains divergent adaptation or vice versa. We find consistent phenotypic divergence between populations occupying distinct habitats. This involves parallel evolution in several traits with known eco- logical relevance in independent evolutionary lineages. Adaptive divergence supersedes homogenizing gene flow even at a small spatial scale. We find evidence that adaptive phenotypic divergence places constraints on gene flow over and above that imposed by geographical distance, signalling the early onset of ecological speciation.

Subnational Patterns of Democracy in Austria, Germany and Switzerland

This article investigates the main political institutions in the sub-national democracies of Austria, Germany and Switzerland. It applies Lijphart’s approach to these German-speaking countries in Western Europe and expands it – following recent advances – by direct democracy. The main finding of the sub-national analysis is that, similar to Lijphart, two dimensions of democracy can be distinguished. While the first can be considered as the ‘consensual dimension’ of democracy, the second represents the ‘rules of the game’. Moreover, and in contrast to analyses at the national level, direct democracy does not constitute a dimension on its own, but forms an important element of consensus decision-making in the sub-national units at hand. Finally, based on cluster analysis three homogenous national clusters were found, but also one cluster with sub-national democracies from Germany and Austria that are more similar to one another than to other Länder within their respective federal states.

Frequency-Dependent Selection Predicts Patterns of Radiations and Biodiversity

Most empirical studies support a decline in speciation rates through time, although evidence for constant speciation rates also exists. Declining rates have been explained by invoking pre-existing niches, whereas constant rates have been attributed to non-adaptive processes such as sexual selection and mutation. Trends in speciation rate and the processes underlying it remain unclear, representing a critical information gap in understanding patterns of global diversity. Here we show that the temporal trend in the speciation rate can also be explained by frequency-dependent selection. We construct a frequency-dependent and DNA sequence-based model of speciation. We compare our model to empirical diversity patterns observed for cichlid fish and Darwin's finches, two classic systems for which speciation rates and richness data exist. Negative frequency-dependent selection predicts well both the declining speciation rate found in cichlid fish and explains their species richness. For groups like the Darwin's finches, in which speciation rates are constant and diversity is lower, speciation rate is better explained by a model without frequency-dependent selection. Our analysis shows that differences in diversity may be driven by incipient species abundance with frequency-dependent selection. Our results demonstrate that genetic-distance-based speciation and frequency-dependent selection are sufficient to explain the high diversity observed in natural systems and, importantly, predict decay through time in speciation rate in the absence of pre-existing niches.

A study of xlcaax-1: Patterns of localization, possible function and usefulness as a developmental marker

Morphogenesis is the process by which the 3-dimensional structure of the developing embryo takes shape. We are studying xlcaax-1, a gene whose product can be used as a molecular marker for several morphogenetic events. We report here the cellular and subcellular localization of the xlcaax-1 protein during development of Xenopus laevis. Whole mount immunocytochemistry and immunoperoxidase staining of tissue sections showed that during development the xlcaax-1 protein accumulation was coincident with the differentiation of the epidermis, pronephros and mesonephros. In the pronephros and mesonephros the xlcaax-1 protein was localized to the basolateral membrane of differentiated tubule epithelial cells. Thus, the xlcaax-1 protein served as a marker for tubule formation and polarization during Xenopus kidney development. Xlcaax-1 may also be used as a marker for the functional differentiation of the epidermis and the epidermally derived portions of the lens and some cranial nerves. The xlcaax-1 protein was most abundant in kidney and immunogold EM analysis showed that the xlcaax-1 protein was highly enriched in the basal infoldings of the basolateral membrane of the epithelial cells in adult kidney distal tubules. The xlcaax-1 protein was also localized in other ion transporting epithelia. The localization pattern and preliminary functional assays of xlcaax-1 suggest that the protein may function in association with an ion transport channel or pump.^ Cell migration and cell-cell interactions play important roles in numerous processes during morphogenesis. One of these is the formation of the pronephric (wolffian) duct (PD), which connects the pronephros to the cloaca. It is currently accepted that in most amphibians the pronephric duct is formed by active migration of the pronephric duct rudiment (PDR) cells along a pre-determined pathway. However, there is evidence that in Xenopus, the PD may be formed entirely by in situ segregation of cells out of the lateral mesoderm. In this study, we showed, using PDR ablation and X. laevis - X. borealis chimeras, that PD elongation in Xenopus required both active cell migration and an induced recruitment of cells from the posterior lateral plate mesoderm. We also showed that PDR cell migration was limited to only a few stages during development and that this temporal control is due, at least in part, to changes in the competence of the PD pathway to support cell migration. In addition, our data suggested that an alkaline phosphatase (APase) adhesion gradient may be involved in determining this competence. ^
