ABSTRACTIn view of the multitude of challenges urban public administration is struggling with, more and more cities are turning towards smart solutions using information and communication technology. Such Smart City approaches revert to data provided in the urban space by sensors, by citizens or by the archives of the authorities aiming at providing public services that increase the quality of life for citizens, optimize mobility within the city or enhance flexibility and responsiveness of public authorities. This article identifies such SC approaches as well as their basic technical requirements for the cities of Vienna, Singapore, and San Francisco and, by compiling the public service portfolios of these cities, creates an integrative, strategic overview of a SC’s range of services. This approach thus helps to create a scientific basis for the evaluation of SC services and to provide a strategic modular toolkit for public managers to plan and design SCs. 相似文献

Commotio cordis secondary to a blunt blow to the chest wall can result in ventricular fibrillation and sudden death in children. While it is commonly reported in adolescents during sporting activities, it may result from non-accidental trauma especially in infants and younger children. We report a case of a 6-month-old baby boy who presented to the emergency department in cardiac arrest. The patient's hospital records, postmortem imaging, and the autopsy results were reviewed. External examination of the infant did not reveal any evidence of trauma. Postmortem imaging revealed multiple healing posterior rib fractures and a metaphyseal corner fracture, both considered fractures highly specific for physical abuse. The autopsy revealed a structurally normal heart with no microscopic abnormalities. The infant's father confessed to hitting the child on the chest after which the child became unresponsive. Given the constellation of postmortem imaging and autopsy findings in addition to the father's confession, the child's death was ruled as a homicide secondary to commotio cordis. Since there are no structural and microscopic abnormalities in the heart autopsy in cases of commotio cordis, timely on-scene investigation and a thorough investigation regarding the mechanism of injury are required to make this diagnosis. Early identification of non-accidental trauma is crucial and can prevent further abuse in other siblings. 相似文献

This symposium demonstrates the potential for throughput legitimacy as a concept for shedding empirical light on the strengths and weaknesses of multi‐level governance, as well as challenging the concept theoretically. This article introduces the symposium by conceptualizing throughput legitimacy as an ‘umbrella concept’, encompassing a constellation of normative criteria not necessarily empirically interrelated. It argues that in order to interrogate multi‐level governance processes in all their complexity, it makes sense for us to develop normative standards that are not naïve about the empirical realities of how power is exercised within multi‐level governance, or how it may interact with legitimacy. We argue that while throughput legitimacy has its normative limits, it can be substantively useful for these purposes. While being no replacement for input and output legitimacy, throughput legitimacy offers distinctive normative criteria—accountability, transparency, inclusiveness and openness—and points towards substantive institutional reforms. 相似文献

Systematic variation of blood droplet volume, the distance fallen and the surface (paper, wood, plastics, tiles) led to the conclusion that the size and the shape of the stains ("fingers", satellites) allowed to deduce the distance fallen but only if the actual surface structure was known. We found that detailed photography at the crime scene was necessary, yet experiments have to be performed due to the extreme influence of the actual surface texture on all characteristics (size, spines, peripheral spatter) of the blood stains. 相似文献

In the Western world, self-incineration is a rare event compared with the Asian countries. The circumstances of death are often unusual, and differentiation from homicide is sometimes possible only after evaluating all the investigation results and findings. In many cases of self-cremation, a fire accelerant is used. In our study material at least 30% of the body surface were burned. Unaffected skin was predominantly found on the back of the body. The cases presented by us are inhomogenous as to the motive and differ from those reported in the literature with regard to gender distribution, scene, motivational situation and psychological constitution. 相似文献

Haplotype data were obtained from a sample of 173 unrelated male individuals from Cartagena (Colombia), for 16 Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635, GATA H4 and GATA A10). No shared haplotypes were observed, demonstrating the usefulness and informative power of these Y-STRs in male lineage identification in Cartagena. Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of Iberian origin. 相似文献
