Im Visier der Ermittlungsbeh?rden: Montagmorgen, 9 Uhr, es klingelt. Vor der Tür steht ein Staatsanwalt mit einem Durchsuchungsbeschluss. Auch wenn die Vorstellung denkbar unangenehm ist, passieren kann das in jeder station?ren Einrichtung, in jedem ambulanten Pflegedienst. Jetzt kommt es darauf an, Ruhe zu bewahren, keine Fehler zu machen und sich richtig zu verhalten.  相似文献

This paper analyzes the productivity of farms across 370 municipalities in the Center-West region of Brazil. A stochastic frontier model with a latent spatial structure is proposed to account for possible unknown geographical variation of the outputs. The paper compares versions of the model that include the latent spatial effect in the mean of output or as a variable that conditions the distribution of inefficiency, include or not observed municipal variables, and specify independent normal or conditional autoregressive priors for the spatial effects. The Bayesian paradigm is used to estimate the proposed models. As the resultant posterior distributions do not have a closed form, stochastic simulation techniques are used to obtain samples from them. Two model comparison criteria provide support for including the latent spatial effects, even after considering covariates at the municipal level. Models that ignore the latent spatial effects produce significantly different rankings of inefficiencies across agents.

We relate technological adoption (of different technologies) with income inequality. In the process, we discover that some technologies, such as aviation, cell phones, electric production, internet, telephone, and TV, are skill-complementary in raising inequality. We construct standardized indexes of skill-complementary technological adoption for modern information and communication technologies (ICT), older ICT, production and transport technologies. We find strong evidence that older ICT and transport technologies (and less frequently modern ICT) tend to increase inequality. Additionally, we discover that results are much stronger in rich countries than in poor ones. Our results are quite robust to a series of changes in specifications, estimators, samples, and measurement of technology adoption. These results may bring insights into the design of incentive schemes for technology adoption.  相似文献

This study contributes to literature on the internationalization of SMEs by analysing the influence of International Market Orientation, Network Capability, and International Entrepreneurial Orientation on the International Performance of this kind of businesses. Particularly, both the direct effects of explanatory variables of International Performance and interdependence relations between them are analysed. Results obtained from a sample of 161 Mexican SMEs using SEM-PLS analysis show that the International Performance of this kind of businesses is favourably influenced by their Network Capability and International Entrepreneurial Orientation, but not by their International Market Orientation. Similarly, it is verified that interdependence relations exist among the explanatory variables of International Performance of SMEs, where positive impact of International Entrepreneurial Orientation is observed on Network Capability and the International Market Orientation of SMEs.  相似文献

Objective: To conduct cost-effectiveness analyses comparing the addition of golimumab to the standard of care (SoC) for treatment of patients with moderate-to-severe ulcerative colitis (UC) who are refractory to conventional therapies in Quebec (Canada).

Methods: An individual patient state transition microsimulation model was developed to project health outcomes and costs over 10 years, using a payer perspective. The incremental benefit estimates for golimumab were driven by induction response and risk of a flare. Flare risks post-induction were derived for golimumab from the PURSUIT maintenance trial and extension study, while those for SoC were derived from the placebo arms of the Active Ulcerative Colitis Trials (ACT) 1 and 2. Other inputs were derived from multiple sources, including retrospective claims analyses and literature. Costs are reported in 2014 Canadian dollars. A 5% annual discount rate was applied to costs and quality-adjusted life-years (QALYs).

Results: Compared with SoC, golimumab was projected to increase the time spent in mild disease or remission states, decrease flare rates, and increase QALYs. These gains were achieved with higher direct medical costs. The incremental cost-effectiveness ratio for golimumab vs SoC was $63,487 per QALY.

Limitations: The long-term flare projections for SoC were based on the data available from the ACT 1 and 2 placebo arms, as data were not available from the PURSUIT maintenance or extension trial. Additionally, the study was limited to only SoC and golimumab, due to the availability of individual patient data to analyze.

Conclusion: This economic analysis concluded that treatment with golimumab is likely more cost-effective vs SoC when considering cost-effectiveness acceptability thresholds from $50,000–$100,000 per QALY.  相似文献

The Governments recent review of the social security system proposed to continue the payment of Child Benefit to rich and poor parents alike. Alexandra Hardie or the University of Exeter, examines the disincentive effects of the current system of universal child benefit and calls instead for its replacement by selective benefits to improve incentives to employment, simplify administration and concentrate state assistance where it is required.  相似文献
