The association between sudden infant death syndrome and immunization is frequently discussed. Serious adverse events following vaccination have generally been defined as those adverse events that result in permanent disability, hospitalization or prolongation of hospitalization, life threatening illness, congenital anomaly or death. They are generally referred to the inherent properties of the vaccine (vaccine reaction) or some error in the immunization process (programme error). The event could also be totally unrelated but only temporally linked to immunization (coincidental event). A fatal case of a 3-month-old female infant, who died within 24 h of vaccination with hexavalent vaccine is presented. Clinical data, post-mortem findings (acute pulmonary oedema, acute pulmonary emphysema), quali-quantitative data collected from immunohistochemical staining (degranulating mast cells) and laboratory analysis with a high level of beta-tryptase in serum, 43.3 microg/l, allows us to conclude that acute respiratory failure likely due to post hexavalent immunization-related shock was the cause of death.  相似文献

This article discusses the case-law on gender recognition of the Colombian Constitutional Court. It argues that the Court, paying attention to queer and trans theory and to the demands of trans activists, has interpreted mainstream constitutional rights in such a way that trans people can have their self-defined identities recognised. The article criticises the limitations of this case-law, which still does not explicitly include non-binary and gender fluid people. On the other hand, it highlights that the Court's doctrine has the potential to challenge both the gender binary and the very category of ‘sex’ or ‘gender’ in the law.  相似文献

STR profiling of animal species has a wide range of applications, including forensic identification, wildlife preservation, veterinary public health protection and food safety. We tested the efficacy of a multiplex PCR-based assay including 11 porcine-specific tetrameric STRs in a population sample of wild boars (n = 142) originating from Piedmont (North West Italy). Multiple deviations from Hardy–Weinberg expectations were observed, mostly due to a reduction in observed heterozygosity indicative of a high degree of inbreeding. A value of θ of 0.046 and an inbreeding coefficient of 0.089 were estimated. Combined power of discrimination and probability of exclusion values for the STR panel were 0.9999999999996 and 0.99989. In order to test the suitability of the method for meat traceability purposes, a domestic pig reference sample (n = 412), consisting of commercial lines commonly used in the meat production process, was also typed. A Bayesian cluster analysis carried out using the observed genotypes, showed a percentage of correct subspecies assignment of individual samples of 0.974 for wild boars and 0.991 for pigs, thus demonstrating the usefulness of the multiplex STR-typing system for discrimination purposes.  相似文献

While organized business is a key actor in regulatory politics, its influence is often conditional on the level of unity or conflict occurring within the business community at any given time. Most contemporary regulatory policy interventions put pressure on the normal mechanisms of business unity, as they are highly targeted and sector‐specific. This raises the question of how business unity operates across a highly variegated economic terrain in which costs are asymmetric and free‐riding incentives are high. In this paper, we empirically assess patterns of business unity within regulatory policymaking across different regulated sectors. Our analysis utilizes data from hundreds of regulatory policy proposals and business community reactions to them in the telecommunications, energy, agriculture, pharmaceutical, and financial sectors over a variety of institutional contexts. We find considerable empirical support for the “finance capital unity” hypothesis – the notion that the financial sector enjoys more business unity than other regulated sectors of the economy. When the financial sector is faced with new regulations, business groups from other sectors frequently come to its aid.  相似文献

This article contributes to current debates on the potential and limitations of transnational environmental governance, addressing in particular the issue of how private and public regulation compete and/or reinforce each other – and with what results. One of the most influential approaches to emerge in recent years has been that of “orchestration.” But while recent discussions have focused on a narrow interpretation of orchestration as intermediation, we argue that there is analytical traction in studying orchestration as a combination of directive and facilitative tools. We also argue that a social network analytical perspective on orchestration can improve our understanding of how governments and international organizations can shape transnational environmental governance. Through a case study of aviation, we provide two contributions to these debates: first, we propose four analytical factors that facilitate the possible emergence of orchestration (issue visibility, interest alignment, issue scope, and regulatory fragmentation and uncertainty); and second, we argue that orchestrators are more likely to succeed when they employ two strategies: (i) they use a combination of directive and facilitative instruments, including the provision of feasible incentives for industry actors to change their behavior, backed up by regulation or a credible regulatory threat; and (ii) they are robustly embedded in, and involved in the formation of, the relevant transnational networks of actors and institutions that provide the infrastructure of governance. © 2017 JohnWiley & Sons Australia, Ltd  相似文献

ABSTRACT

The problem of cyberterrorism, despite its contested nature, is an important area of research. Scholars agree that the most dangerous targets for such attacks are critical infrastructure and organizations that are vital to society due to their interconnectedness to the modern world and their increasing reliance on the cyber domain for their operations. Thus, their security and protection against cyberterrorism is of elevated importance. Given the lack of documented cases of cyberterrorism, the purpose of this article is to simulate the threat of a terrorist act on a critical infrastructure, using a computer virus and to investigate how the individual behavior of employees affects security.  相似文献

ABSTRACT

There is debate in the literature on whether or not general management principles are applicable to the study and practice of public administration. This research responds by exploring how local officials manage the performance of public services with private good characteristics, where general management principles could be embraced for service delivery. The relationship between operational and financial indicators is explored within the functional areas of water and sewer, with the hypothesis that operational outcomes impact financial outcomes similar to private enterprises. Because the findings do not support this hypothesis, the authors conclude that general management principles may not be applicable to all forms of administration given that public cannot be removed from the management of public services even with private good characteristics.  相似文献
