ABSTRACTThe paper deals with the issue of overpricing of public procurement in low-performing EU countries. It examines a uniquely large sample of public procurement in 11 Central and Eastern European countries. Hierarchical regression is used to analyze the factors that influence public contract. Our results indicate that institutional factors have a greater impact on overpricing than individual decisions by the contracting authority. Our analysis for low-performing EU countries provides interesting results and also draws attention to behavior that is not typical of the better established and more advanced EU countries. Our results are particularly important for public policy in each country, as they show the direction of regulatory action in the field of public procurement. The results introduce a debate on the appropriateness of “one size fits all” regulations within the EU. 相似文献

We distinguish between (i) voting systems in which voters can rank candidates and (ii) those in which they can grade candidates, using two or more grades. In approval voting, voters can assign two grades only—approve (1) or not approve (0)—to candidates. While two grades rule out a discrepancy between the average-grade winners, who receive the highest average grade, and the superior-grade winners, who receive more superior grades in pairwise comparisons (akin to Condorcet winners), more than two grades allow it. We call this discrepancy between the two kinds of winners the paradox of grading systems, which we illustrate with several examples and whose probability we estimate for sincere and strategic voters through a Monte Carlo simulation. We discuss the tradeoff between (i) allowing more than two grades, but risking the paradox, and (ii) precluding the paradox, but restricting voters to two grades. 相似文献

Most chemical and physical methods employed in visualizing latent marks have shown detrimental effects on human health and, therefore, some research groups have directed their attention to the utilization of various (bio)polymers with the aforementioned purpose. Although chitosan is widely used in medicine, pharmacy, food, and drug delivery systems, there are very few studies that address this biopolymer utilization in forensic applications, such as the detection of latent fingerprints. We used chitosan crosslinked with sodium tripolyphosphate and conjugated with L‐lysine to enhance the visualization of latent fingerprints, due to its ability to interact with fingerprint sweat residues. These conjugates were prepared using different (w/w) amounts of chitosan and tripolyphosphate (6/1; 4/1; 1/1; 1/4; and 1/6), and those with the most promising results (i.e., 6/1 formulation) were investigated in detail. Fourier transform infrared (FT‐IR) spectroscopy confirmed interactions between components of the systems. Optical microscopy and scanning electron microscope (SEM) analysis showed that prepared powder formulations were uniform in size and confirmed that chitosan/tripolyphosphate/lysine conjugates bind easily to the sweat and lipid residues present in the latent fingerprints. The testing of prepared conjugates demonstrated the potential of these systems as bio‐based powder substitution for commercially available powders. 相似文献

The New Economic Governance (NEG) in the European Union is a core element of a neoliberal crisis constitutionalism that has to be seen as blatantly deficient when measured with democratic yardsticks. Strongly normative criticism generates important findings, but ignores the economic dimension of damage to democracy. From the perspective of capitalism theory, the NEG can be recognised as a product of a capitalistic land grab (“Landnahme”) of the political field and as a system of institutions whose functional logic corresponds to the imperative of a crisis-ridden economy characterised by the financial markets. In this context, viewpoints are confirmed that regard the integration of the economic causes of blatant deficits of democracy as an essential element of a new type of inclusive democracy project. The work on a new economic democracy as a core element of such a democracy project thus also becomes a desideratum for a public sociology that wishes to contribute evidence-based knowledge to social disputes. 相似文献

There has been a long-standing discussion since the 1980s about the question whether new production models harbor a potential for extended employee participation and involvement, in most cases with disillusioning results. This paper is concerned with so called “agile methods”, which play an important part in the area of knowledge work in the course of the digital transformation. On the basis of two case studies from software development and industrial R&D, the paper examines the concrete implementation of these methods and the employees’ perspective upon them and their consequences. The result is that agile methods present a potential for extended employee participation and involvement; however, the realization of this potential depends on the concrete way how the agile concept of “empowerment” is implemented. 相似文献

The article examines the triangular relation between ecological sustainability, economic growth and liberal democracy and asserts that this relation is dramatically altered in the face of the increasingly imminent manifestation of the “limits to growth.” In the course of this process, the contours of a “democratic post-growth regime” are beginning to show – though in a very different way than was hoped for by the majority of transformation researchers. Intent on making a contribution to re-relating those normative factions of sustainability research which share a transformative self-understanding to the scientific analysis of modern societies, the paper shows how central eco-political and democracy-related narratives that have dominated the debate for decades have lost credibility, thus opening up the space for a readjustment of the named triangular relation. Applying a social theory perspective, it is subsequently shown how, in the face of modern conceptions of subjectivity and, at best, moderate growth rates, democracy is increasingly turning into an instrument for the unflinching sustainment of unsustainable lifestyles. As it turns out, modern consumer societies persist in their “politics of non-sustainability” more uncompromisingly than ever before. 相似文献

Since the 1980s, Japan’s war memory has strained its relations with South Korea and China, to a less degree, the USA. Two of the thorniest issues are the comfort women and the US atomic bombing of Japan. Before the Obama administration announced its policy pivot to Asia in 2011, both Japanese and American leaders were reluctant to make amends for the past acts of their countries. However, in 2015, the Japanese conservative Prime Minister Abe reached an agreement with South Korea that “finally and irreversibly” resolved the comfort women issue, thus achieving a historic reconciliation between the two countries. In 2016, then President Obama visited Hiroshima to commemorate the atomic bomb victims. Then, in December 2016, the comfort women issue resurfaced in Japan and South Korea relations, indicating a failure of the reconciliation. Why did the USA change its policy on historical issues involving Japan? Why did Abe and the South Korean President Park Geun-hye settle the comfort women issue? Why did Obama visit Hiroshima? Why did the reconciliation fail? In this article, I propose a rational choice theory to answer these questions. Applying the proposed theory and relying on available evidence, I argue that the settlement of the comfort women issue and Obama’s visit to Hiroshima are important components of Obama’s pivot to Asia to balance China’s rise. The reconciliation failed mainly because it did not resolve the historical justice issue promoted by the human rights norms. I discuss some implications for reconciliation in Northeast Asia. 相似文献

Food and health regulations are increasingly being pushed onto the political agenda, with rising concerns about genetically modified foods, obesity rates, and vaccination. Public beliefs and attitudes on these issues often conflict with the scientific evidence, yet we know relatively little about what influences opinion on these issues. The public lacks clear partisan cues, and many food and health attitudes cut across the ideological spectrum. We argue that these issues represent new ‘purity’ attitudes that are driven by the emotion of disgust. Across three studies, both by measuring individuals’ trait disgust sensitivity and experimentally inducing an emotional state of disgust, we demonstrate the impact of disgust on food and health policy attitudes. Our results show that greater sensitivity to disgust is associated with support for organic foods, opposition to genetically modified foods, and anti-vaccination beliefs. However, we find only limited evidence that experimentally manipulated disgust affects attitudes toward genetically modified and organic foods. Overall, our results demonstrate that disgust plays an important role in attitudes regarding public health and broadens our understanding of purity attitudes. 相似文献

Those who turn out in American primary elections are a small and unrepresentative subset of the population. Why do citizens forgo participation in nominating contests yet vote in general elections? We argue that limited contact lowers participation in primary elections. We present results from a randomized field experiment with near 150,000 letters in California’s 2014 primary. Each letter went to one of the four million Californians who had participated in recent general elections but not in primaries. We find that a single letter increased turnout by 0.5 points from a base rate of 9.3 percent. This increase is more than twice the average effect calculated in a recent meta-analysis and represents a proportional increase of 5.4 percent. Our experiment shows that registrants who typically abstain from primaries—and who are thus often ignored by campaigns—can be effectively mobilized. 相似文献
