Plus ça change: health sector reforms in Greece

Changes in the health care sector in Greece since the pathbreaking introduction of the National Health System (NHS) in 1983 have been sluggish. Twenty years after its inception and a series of attempts to reform it, the NHS remains centralized, fragmented in terms of coverage, and quite far removed from its principles of equity and efficiency. Being part of an idiosyncratic welfare state, the health care system is bound to reflect the particularities of Greek society and economy, namely, clientelism, a weak formal-and a thriving informal-economy, the lack of a strong administrative class, a weak labor movement, and strong organized interests. As a result, several ambitious reform plans have failed repeatedly owing to an array of interrelated economic, political, and social factors that channel potential changes toward the trodden path. This constellation creates unfavorable conditions for the introduction and implementation of major reforms.     

Use of PCR-RFLP for differentiation of calliphorid larvae (Diptera,Calliphoridae) on human corpses

Blowfly larvae found on human corpses are important for the estimation of the postmortem interval (PMI) and other questions of forensic relevance. Some of these species are difficult to differentiate morphologically, therefore a molecular method was elaborated for species identification. Specific fragments of the COI and COII region of the mitochondrial DNA (mtDNA) were amplified followed by digestion with different restriction enzymes. Using a 1.3 kb fragment, identification of Lucilia sericata, Calliphora vicina and Calliphora vomitoria was possible by digestion with only one restriction enzyme using either DraI or HinfI. Furthermore, we sequenced 349 bp (a part of the COI and COII regions) from the same three species and found 34 nucleotide distinctions between C. vicina and L. sericata, 30 between C. vomitoria and L. sericata and 15 between the two Calliphora species. These results aid in quick identification of species used for estimation of PMI.     

Hiking the Huashan Mountain

正After a two-hour ride from Xi'an, capital of northwest China's Shaanxi Province, the bus reached Huashan Mountain, one of the five sacred Taoist mountains in China. It took me almost five hours to hike up to the western peak.     

Entrepreneurship ecosystems: an agent-based simulation approach

Knowledge acquisition and development of capabilities constitutes a key perspective in studies regarding the formation of new ventures. When examining entrepreneurship ecosystems, we find that the composition of a region influences the new knowledge acquired by the venture. The main aim of this study is to examine the influence of the new venture, the entrepreneur’s social capital, and the firm performance on the new venture’s knowledge acquisition activities. In particular, the study examines how the institutional context of a region influences new ventures’ knowledge acquisition actions during its growth, and in turn the level of sustained entrepreneurial activity within the region. The paper focuses on the formation of alliances by new ventures, one particular form of knowledge acquisition process that has been established as critical to new venture success in the high technology sector. The mechanisms for acquiring and transforming knowledge have the greatest impact on new venture formation, and in this context, the concepts of strategic knowledge arbitrage and strategic knowledge serendipity (SKARSE?) are validated through an agent-based simulation model. The main results focus on the effects of interactions between entrepreneurs and institutions in the process of new venture formation from a knowledge creation, dissemination, and absorption perspective.     

Compensation and Compliance: Sources of Public Acceptance of the U.K. Supreme Court's Brexit Decision

The perception that a high court's decision is binding and final is a crucial prerequisite for its ability to settle political conflicts. Under what conditions are citizens more likely to accept controversial judicial rulings? Mass acceptance is determined, in part, by how rulings are framed during public debate. This paper takes a broad view of the strategies and actors that influence the discursive environment surrounding judgments, calling attention to hitherto unexamined determinants of mass acceptance. We theorize that third parties can boost acceptance by pledging compliance, and that courts can moderate opposition by compensating losers. We also look at how populist attacks on judiciaries, common in contemporary democracies, affect acceptance. We test these propositions using a survey experiment conducted in the aftermath of the UK Supreme Court's Brexit decision, the most salient judgment handed down by this court to date. The paper moves the literature on courts and public opinion beyond the United States, and presents evidence backing largely untested assumptions at the heart of models of judicial behavior regarding the benefits of crafting rulings with an eye on the preferences of key audiences.     

Measuring the intercondylar shelf angle using radiographs: intra- and inter-observer error tests of reliability

This study presents a test of intra- and inter-observer measurement error rates of the intercondylar shelf angle of the distal femur, as measured on lateral radiographs. This measurement is the central element of a method to determine racial affiliation from the distal femur. Four observers independently radiographed a set of 33 complete and partial femora from collections housed at the Joint POW/MIA Accounting Command, Central Identification Laboratory. Each observer then measured the intercondylar shelf angles in each radiograph, following the original method's guidelines. A supplementary inter-observer error test was conducted by four additional observers on one set of radiographs. Statistically significant differences were found for both intra- and inter-observer error based on the results of Student's t-tests, paired samples t-tests, and ANOVA analyses. The results of this study indicate that further experimentation should be undertaken in order to develop refined measurement techniques that may help improve standardization and reduce the observer error rates.
