Wahlbeteiligung bei Europawahlen : eine empirische Studie zu Deutschland und Polen

In der Arbeit wird die Wahlbeteiligung bei Europawahlen analysiert. Es geht um die Beantwortung der Frage, ob die individuelle Wahlteilnahme in alten und neuen EU-Mitgliedsstaaten bzw. alten und jungen Demokratien auf die gleichen Erklärungsgrößen zurückgeht oder ob möglicherweise Unterschiede zwischen beiden Ländergruppen bestehen. rnAls Bezugspunkt dient die Europawahl, die im Juni 2009 stattfand: Bei dieser Wahl fällt nicht nur die generell niedrige Beteiligung auf, sondern auch erhebliche Niveauunterschiede zwischen den einzelnen Mitgliedsstaaten. Um diesen Befund erklären zu können, wird zunächst ein theoretisches Erklärungsmodell entwickelt, das sich auf die folgenden fünf Dimensionen bezieht: politisches System der EU, europäische politische Gemeinschaft, Wählermobilisierung während des Europawahlkampfes, Gewohnheitswahl und Einschätzung der staatlichen sowie der eigenen wirtschaftlichen Lage. Als Erklärungsgröße werden in den fünf Bereichen jeweils unterschiedlich stark ausgeprägte Defizite in den beiden Ländergruppen angenommen. rnExemplarisch werden Deutschland und Polen untersucht. Die empirischen Analysen basieren auf dem umfangreichen Datensatz der European Election Study 2009 (ESS), hier werden die Daten der Voter Study verwendet. Nicht alle Hypothesen lassen sich im Rahmen der Arbeit bestätigten, nur ein Teil der unabhängigen Variablen hat auch im multivariaten Modell noch einen Einfluss auf die Europawahlbeteiligung. rnFür Deutschland zeigen die Ergebnisse, dass Wahlnorm und Wählermobilisierung einen größeren Effekt auf die Stimmabgabe ausüben als die Nutzenseite (Effektivität) der Wahlen. Im zweiten Modell, das für die polnischen Befragten berechnet wurde, erweisen sich nur zwei der unabhängigen Variablen als signifikant, d.h. nur die Einschätzung der Effektivität der Wahl und die internalisierte Wahlnorm haben einen Einfluss auf die Wahlteilnahme. Von der Effektivitätseinstufung geht eine größere Erklärungskraft aus als von der Wahlnorm; in diesem Modell überwiegt folglich die Nutzenseite der Europawahl. Es kann gezeigt werden, dass die unterschiedlichen Beteiligungsraten in den beiden Staaten durch unterschiedlich stark ausgeprägte Defizite in den Bereichen des politischen Systems und der Wahlnorm zustande kommen. Die Defizite sind in Polen stärker ausgeprägt und können so die niedrigere Wahlbeteiligung erklären. Darüber hinaus kann resümiert werden, dass die Nutzenseite der Europawahl in Polen einen stärkeren Einfluss auf die Beteiligung ausübt als in Deutschland.

Evaluating the relationship between moisture induced expansion and horizontal stress orientation in samples from the nonesuch formation

High horizontal stresses can cause numerous ground control problems in mines and other underground structures ultimately impacting worker safety, productivity and the economics of an underground operation. Mine layout and design can be optimized when the presence and orientation of these stresses are recognized and their impact minimized. A simple technique for correlating the principal horizontal stress direction in a sedimentary rock mass with the preferential orientation of moisture induced expansion in a sample of the same rock was introduced in the 1970s and has since gone un-reported and unused. This procedure was reexamined at a locality near the original test site at White Pine, Michigan in order to validate the original research and to consider its usefulness in mining and civil engineering applications in high horizontal stress conditions. This procedure may also be useful as an economical means for characterizing regional stress fields.

A Targeted Survey for Scrapie in Jos Plateau State, Nigeria

Scrapie, a disease of sheep and goats with a progressive course and fatal outcome, has not been identified in Nigeria. Anecdotal scrapie reports by livestock workers abound. Livestock diseases like scrapie form huddles in livestock economics of countries. For 8 months we surveyed for scrapie targeting emergency/casualty slaughter sheep and goats in Jos, Nigeria. We clinically examined 510 sheep and 608 goats of local breeds, aged from 12 months to 5 years. In total 31 (5.10%) goats and no sheep were clinically suspicious for scrapie. Caudal brainstem tissues of suspect animals collected postmortem were analyzed for the disease specific form of the prion protein, PrPSc, using Bio-Rad’s TeSeE ELISA rapid test kit. No sample was positive for scrapie. Fluorescent antibody test for rabies and H&E staining on samples were carried out for differential diagnosis. These showed no pathological lesions indicative for neurological disease. While our findings do not exclude the presence of scrapie in Jos, we demonstrate that targeted sampling of small ruminants for neuroinfectious disease is feasible in developing countries, pointing to the possibility of implementing such a monitoring scheme in Nigeria to prevent economic losses in small ruminant livestock as scrapie caveats from endemic countries have shown.

Demo -- Closer to Cloud-RAN: RAN as a Service

Commoditization and virtualization of wireless networks are changing the economics of mobile networks to help network providers (e.g., MNO, MVNO) move from proprietary and bespoke hardware and software platforms toward an open, cost-effective, and flexible cellular ecosystem. In addition, rich and innovative local services can be efficiently created through cloudification by leveraging the existing infrastructure. In this work, we present RANaaS, which is a cloudified radio access network delivered as a service. RANaaS provides the service life-cycle of an ondemand, elastic, and pay as you go 3GPP RAN instantiated on top of the cloud infrastructure. We demonstrate an example of realtime cloudified LTE network deployment using the OpenAirInterface LTE implementation and OpenStack running on commodity hardware as well as the flexibility and performance of the platform developed.

Dexmedetomidine versus standard care sedation with propofol or midazolam in intensive care: an economic evaluation.

INTRODUCTION Dexmedetomidine was shown in two European randomized double-blind double-dummy trials (PRODEX and MIDEX) to be non-inferior to propofol and midazolam in maintaining target sedation levels in mechanically ventilated intensive care unit (ICU) patients. Additionally, dexmedetomidine shortened the time to extubation versus both standard sedatives, suggesting that it may reduce ICU resource needs and thus lower ICU costs. Considering resource utilization data from these two trials, we performed a secondary, cost-minimization analysis assessing the economics of dexmedetomidine versus standard care sedation. METHODS The total ICU costs associated with each study sedative were calculated on the basis of total study sedative consumption and the number of days patients remained intubated, required non-invasive ventilation, or required ICU care without mechanical ventilation. The daily unit costs for these three consecutive ICU periods were set to decline toward discharge, reflecting the observed reduction in mean daily Therapeutic Intervention Scoring System (TISS) points between the periods. A number of additional sensitivity analyses were performed, including one in which the total ICU costs were based on the cumulative sum of daily TISS points over the ICU period, and two further scenarios, with declining direct variable daily costs only. RESULTS Based on pooled data from both trials, sedation with dexmedetomidine resulted in lower total ICU costs than using the standard sedatives, with a difference of €2,656 in the median (interquartile range) total ICU costs-€11,864 (€7,070 to €23,457) versus €14,520 (€7,871 to €26,254)-and €1,649 in the mean total ICU costs. The median (mean) total ICU costs with dexmedetomidine compared with those of propofol or midazolam were €1,292 (€747) and €3,573 (€2,536) lower, respectively. The result was robust, indicating lower costs with dexmedetomidine in all sensitivity analyses, including those in which only direct variable ICU costs were considered. The likelihood of dexmedetomidine resulting in lower total ICU costs compared with pooled standard care was 91.0% (72.4% versus propofol and 98.0% versus midazolam). CONCLUSIONS From an economic point of view, dexmedetomidine appears to be a preferable option compared with standard sedatives for providing light to moderate ICU sedation exceeding 24 hours. The savings potential results primarily from shorter time to extubation. TRIAL REGISTRATION ClinicalTrials.gov NCT00479661 (PRODEX), NCT00481312 (MIDEX).

Schumpeter and Personal Capitalism

In an earlier paper, I criticized Schumpeter's account of the obsolescence of the entrepreneur in Capitalism, Socialism, and Democracy. That account rests, I argued, on a confusion about the nature of scientific knowledge and its role in the competences of the firm. This paper is an attempt to take up the argument again, moving it away from the doctrine-historical into the provinces of the economics of organization. Drawing on the work of Max Weber, as well as on a case study of the Swiss watch industry, the paper argues for the ineradicable role of personal capitalism, properly understood.

Credible Criminal Enforcement

Economic models of crime and punishment implicitly assume that the government can credibly commit to the fines, sentences, and apprehension rates it has chosen. We study the government's problem when credibility is an issue. We find that several of the standard predictions of the economic model of crime and punishment are robust to commitment, but that credibility may in some cases result in lower apprehension rates, and hence a higher crime rate, compared to the static version of the model.

Property Law

This chapter examines the economics of property rights and property law. Property law is a fundamental part of social organization and is also fundamental to the operation of the economy because it defines and protects the bundle of rights that constitute property. Property law thereby creates incentives to protect and invest in assets and establishes a legal framework within which market exchange of assets can take place. The purpose of this chapter is to show how the economics of property rights can be used to understand fundamental features of property law and related extra-legal institutions. The chapter will both examine the rationale for legal doctrine and the effects of legal doctrine regarding the exercise, enforcement, and transfer of rights. It will also examine various property rights regimes including open access, private ownership, common property and state property. The guiding questions are: How are property rights established? What explains the variation in the types of property rights? What governs the use and transfer of rights? And, how are property rights enforced?

Crecimiento económico, mercado inmobiliario y ausencia de política de suelo : un análisis de la expansión del espacio residencial de la Ciudad de Buenos Aires en los 2000

A pesar del crecimiento económico y del notable dinamismo que caracterizó al mercado inmobiliario y la construcción a partir de la recuperación económica de 2003 en Argentina, se restringieron las históricas condiciones para acceder a una vivienda en ámbitos urbanos bien servidos y ubicados. En la lógica actual del contexto macroeconómico y en la lógica del comportamiento territorial y de los agentes económicos del mercado inmobiliario pueden rastrearse algunos elementos para comprender este aspecto que tan caro le vale al derecho a la ciudad. Para atender esta hipótesis se pregunta lo siguiente: ¿Cuál fue la evolución territorial del precio del suelo entre 2001 y 2006 en la ciudad de Buenos Aires?, ¿cuáles fueron los principales factores que motivaron tal comportamiento y, específicamente, qué papel jugaron los agentes económicos del mercado inmobiliario en esa dinámica?, y ¿qué efectos viene teniendo el contexto macroeconómico actual el singular comportamiento de este mercado en el acceso a la vivienda?
