Do more placement officers lead to lower unemployment? : evidence from Germany

"In this paper we examine the effect of a pilot project of the German Federal Employment Agency, where in 14 German local employment offices the caseload (number of unemployed per caseworker) was significantly reduced. Since the participating local offices were not chosen at random, we have to take into account potential selection bias. Therefore, we rely on a combination of matching and a difference-in-differences estimator. We use two indicators of the offices' success (unemployment rate, growth of the number of SCIII clients). Our results indicate a positive effect of a lower caseload on both outcome variables."

Contingent Valuation of Mining Land Reclamation in East Germany

Large parts of East German landscapes are formed by lignite mining activities. The mining pits destroy vast areas of the existing cultural landscapes. These areas have to be made re-accessible to society through extensive reclamation projects after mining has been finished. For an appraisal of the social benefits that need to be compared to the costs of these projects the Contingent Valuation Method (CVM) is the method of choice. The CVM measures the willingness to pay of households for such a project. This paper reports the findings of a Con-tingent Valuation study assessing the social utility created by a reclamation project north of the city of Cottbus in Brandenburg, Germany. The goal of the study is threefold. Firstly, the affected population's aggregate willingness to pay for the planned reclamation project is cal-culated; it amounts to 2.7 mil. Euro per year. Secondly, the determinants of this willingness to pay are analyzed. Apart from the expected positive impact of income on willingness to pay we find that it is also influenced by people's recreational activities, their general attitudes to-wards public spending and by their concerns about the economic situation. Thirdly, the study explores methodological specifics of an application of the CVM to Germany, especially in East Germany, by focusing on the appropriate design of the willingness to pay question which is an important feature still controversially discussed in the literature.contingent valuation;

Replication Studies on Significant Differences in Personality Profiles of Securely and Insecurely Attached Psychotherapists and Dentists

This study contributes to the therapist variable in general and the personality profile of securely and insecurely attached psychotherapists and other healthcare professionals in particular. In a preceding study, it has been found that insecurely attached psychotherapists differ in nine personality styles from securely attached ones. The aim of the present study was to replicate these findings and to investigate whether they also apply to other health professions such as dentists. About 891 subjects from two German professional societies for hypnosis were surveyed online with a personality questionnaire [Personality Styles and Disorder Inventory (PSDI)] and an attachment questionnaire [Relationship Scale Questionnaire (RSQ)]. Since these subjects were interested in hypnosis and used it in their practice (HYP), 150 dentists without a hypnosis context (NONHYP) were studied as a control group with the same survey. The results of the preceding attachment study could be replicated: Insecurely attached healthcare professionals differed significantly from securely attached ones in the same nine (plus one, i.e., 10) personality styles if they use psychological methods including hypnosis. If they do not use psychological methods (like the NONHYP dentists), they differ in half of the personality styles. No within-sample and no between-sample differences have been found in the assertive/antisocial (AS) personality style. No within-sample differences have also been found in the conscientious/compulsive (ZW) and the intuitive/schizotypal (ST) personality styles. However, large between-sample differences were obvious in ZW and the ST. Both of the samples of the dentist were much more compulsive than the two psychotherapeutic samples. In addition, both of the HYP samples were much more schizotypal than the NONHYP samples. The latter is the general signature of those individuals who are interested in hypnosis and were metaphorically termed homo hypnoticus. It seems that AS, ZW, and ST are independent of attachment

Cost-Effectiveness of Treatment Decisions for Early Childhood Caries in Infants and Toddlers: A Systematic Review.

Background and Objectives: Early childhood caries (ECC) is a multifactorial, biofilm-mediated, sugar-related, dynamic disease of primary dental hard tissues occurring in varying degrees of severity in infants and toddlers. Untreated ECC may lead to pain, infections, and severe systemic complications. The aim of this study was to systematically review and evaluate the scientific evidence on the cost-effectiveness of treatment decisions in ECC in infants and toddlers. Materials and Methods: Observational epidemiological studies, i.e., cohort studies, case-control studies, and randomized controlled trials, reporting cost-effectiveness of treatment decisions in ECC in infants and toddlers were included in the systematic review following the PRISMA guidelines. Using an ad hoc search with search terms or keywords (MeSH), electronic databases Embase, MEDLINE via PubMed, Scopus, and gray literature were searched. Results: The search identified 494 articles, of which 446 remained after removing duplicates. A total of 417 articles were excluded after title and abstract evaluation; 29 full-text articles were screened for eligibility, and five articles were discarded. Twenty-four full-text articles were included in the systematic review, assigning 17 to prevention and seven to restoration. Results were heterogeneous; comparability of included studies is difficult because of the different methodologies used. Conflicting efficacies were demonstrated for different interventions implemented, and cost-effectiveness data were documented. Conclusions: Socioeconomic, cultural, and ethnic differences must be considered when comparing conditions in terms of cost-effectiveness. A paradigm shift from surgical towards preventive treatment decisions can be observed. Cost-effectiveness studies on therapies for ECC in infants and toddlers are needed to identify the best practice approach and the most cost-effective therapy decisions

Towards a deep reinforcement learning integration into model-based systems engineering

The integration of Deep Reinforcement Learning (DRL) in Model-Based Systems Engineering (MBSE) is a promising approach that can lead to significant benefits for system designers and developers. DRL is a branch of machine learning where an agent learns to make decisions by interacting with an environment, receiving feedback in the form of rewards or punishments that indicate the quality of its actions, and adjusting its decision-making policy to maximize the cumulative reward over time. MBSE provides a structured approach to system design, which can help to clarify system requirements, identify potential issues, and improve the overall efficiency of the system development process. This model-based approach can be particularly useful for DRL, which requires a clear understanding of the system environment and objectives to develop the system’s behavior. We propose a method for integrating DRL into MBSE, where the desired system behavior is defined in a model-based representation using a modeling language to describe the relevant design components for DRL. The method's model framework is applied and evaluated to an example use case using SysML as the modeling language. This integration enables system designers to use DRL with the benefits and support of MBSE
