This article aims to analyse the European Parliament's (EP) position in the reform of the European economic governance, in particular after the adoption of the ‘six‐pack,’ the ‘two‐pack’ and the ‘fiscal compact.’ References are made to the involvement of the EP in the decision‐making process that led to the adoption of the new measures as well as to the substantive role assigned to this institution in the new regulatory framework. The article argues that the new provisions, which undermine the budgetary authority of national parliaments while, at the same time, designing a limited role for the EP—though strengthened compared to the previous version of the Stability and Growth Pact—can jeopardise the effectiveness of the landmark principle of ‘no taxation without parliamentary representation’ in the EU. 相似文献

Corporate social responsibility (CSR) is the incorporation of environmental and social responsibilities into the business activity, in line with the economic responsibility that firms have traditionally focused on. The social entrepreneur is a type of entrepreneur who seeks to resolve a social or environmental problem through the application of a business model, motivated by the aim of helping others and pursuing positive social change. A key aspect of social entrepreneurship (SE) is therefore the creation of social wealth. Both concepts pursue positive social change, but unlike social entrepreneurs, the objective of a responsible firm is not to solve social issues created by others, rather to understand and limit the social and environmental impacts of their profit-generating activities. In recent decades, research on CSR has grown considerably, whereas SE has only begun to receive serious academic attention quite recently. Crucially, few studies have tried to link and differentiate the two areas. Due to the increasing interest in both concepts nowadays, the need to clarify the similarities and differences between them is greater than ever, and is the principal aim of this work. 相似文献

In 2012, the simultaneous elections at the federal, state and municipal levels in Mexico reopened the debate about the path of democratic consolidation in the country. With the return of the Revolutionary Institutional Party to the presidency in 2013, there are renewed signs that Mexican democratic consolidation is underway. Particularly important in this process is that the 2012 gubernatorial and mayoral elections have been more competitive, resulting in higher political alternation in power between political parties. Under a changing subnational political context, there are indications that subnational politicians are no longer under the shadow of a dominant party system. As a more consolidated federal democracy, the political landscape in Mexico has become more complex. 相似文献

Real-time PCR designs to estimate nuclear and mitochondrial DNA copy number in forensic and ancient DNA studies 总被引:8,自引:0,他引:8

We explore different designs to estimate both nuclear and mitochondrial human DNA (mtDNA) content based on the detection of the 5' nuclease activity of the Taq DNA polymerase using fluorogenic probes and a real-time quantitative PCR detection system. Human mtDNA quantification was accomplished by monitoring the real-time progress of the PCR-amplification of two different fragment sizes (113 and 287 bp) within the hypervariable region I (HV1) of the mtDNA control region, using two fluorogenic probes to specifically determine the mtDNA copy of each fragment size category. This mtDNA real-time PCR design has been used to assess the mtDNA preservation (copy number and degradation state) of DNA samples retrieved from 500 to 1500 years old human remains that showed low copy number and highly degraded mtDNA. The quantification of nuclear DNA was achieved by real-time PCR of a segment of the X-Y homologous amelogenin (AMG) gene that allowed the simultaneous estimation of a Y-specific fragment (AMGY: 112 bp) and a X-specific fragment (AMGX: 106 bp) making possible not only haploid or diploid DNA quantitation but also sex determination. The AMG real-time PCR design has been used to quantify a set of 57 DNA samples from 4-5 years old forensic bone remains with improved sensitivity compared with the slot-blot hybridization method. The potential utility of this technology to improve the quality of some PCR-based forensic and ancient DNA studies (microsatellite typing and mtDNA sequencing) is discussed. 相似文献

Age estimation using DNA methylation levels has been widely investigated in recent years because of its potential application in forensic genetics. The main aim of this study was to develop an age predictor model (APM) for blood samples of deceased individuals based in five age-correlated genes. Fifty-one samples were analyzed through the bisulfite polymerase chain reaction (PCR) sequencing method for DNA methylation evaluation in genes ELOVL2, FHL2, EDARADD, PDE4C, and C1orf132. Linear regression was used to analyze relationships between methylation levels and age. The model using the highest age-correlated CpG from each locus revealed a correlation coefficient of 0.888, explaining 76.3% of age variation, with a mean absolute deviation from the chronological age (MAD) of 6.08 years. The model was validated in an independent test set of 19 samples producing a MAD of 8.84 years. The developed APM seems to be informative and could have potential application in forensic analysis. 相似文献

ABSTRACTThis article looks at everyday encounters in Mostar to investigate how boundaries are enacted and displaced by its dwellers. Drawing on participant observation in two cafes, it considers boundaries not only in their spatial capacity, but in a confluence of space and time. It reflects on how owners and customers mobilize the idea of the pre-war city as a space of interethnic tolerance to criticize the contemporary city. It discusses how the creation of temporal boundaries complicate the narrative of the divided city and sheds light on attempts to restore places of co-existence in sharp contrast to the prevalent social order. 相似文献

Nudges are popular types of interventions. Recent years have seen the rise of ‘norm-nudges’—nudges whose mechanism of action relies on social norms, eliciting or changing social expectations. Norm-nudges can be powerful interventions, but they can easily fail to be effective and can even backfire unless they are designed with care. We highlight important considerations when designing norm-nudges and discuss a general model of social behavior based on social expectations and conditional preferences. We present the results of several experiments wherein norm-nudging can backfire, and ways to avoid those negative outcomes.

Previous research examined whether justice effects are comparable, focusing on quantitative differences in justice effects. This study examines whether justice perceptions are structured similarly or whether they are qualitatively different across working populations from 13 nations. Confirmatory factor analysis and multi-group analysis show that Colquitt??s (J Appl Psychol 86:386?C400, 2001) four-dimensional model of justice works well across these samples. However, factor intercorrelations and reliabilities are found to systematically vary between cultural samples. Perceptions of justice are more highly intercorrelated in power distant and collectivistic samples, in line with extensions of the relational model of authority. Score reliabilities were lower in collectivistic settings. 相似文献

Abstract: A critical review of Kahana and Hiss’ study on identification from bone trabecular pattern and a test of their method conducted on the humerus are presented. Bone trabecular pattern was studied through the generation of a numerical file representing the gray scale. Using the correlation coefficient, several pairwise comparisons between numerical files were performed. The test gave nearly 30% of incorrect exclusions (the method did not recognize couples of radiographs belonging to the same subject) and 50% of misidentifications (the method recognized couples of radiographs belonging to different subjects, as belonging to the same subject); therefore, this research shows that at the present time, it is not possible to safely quantify identification through bone density patterns, of the proximal humerus taken from thoracic X‐rays. Thus, an “easy”—but dangerous—use of trabecular density patterns on this specific type of radiogram as an identification method should be currently avoided. 相似文献
