Schedules based on tooth development are useful in age assessments of children, but in early infancy they are based on only a few studies. The radiographic appearance of the mandibular symphysis during the first postnatal months has not gained attention. The present study describes the formation of teeth and the development of fusion between the mandibular halves during the first five postnatal months, as seen in panoramic tomograms taken in medicolegal autopsies of 29 ethnic Finns, 19 boys and 10 girls, at the Department of Forensic Medicine, University of Helsinki. In the majority of the infants, the criteria of sudden infant death (SID) were fulfilled. The stages of tooth formation used were those applied by Moorrees et al. with one modification (Nystr?m et al.). Mineralization of all primary teeth proceeded rapidly during the first postnatal months, the change being on average two developmental stages in four months. Considerable variation in tooth development existed in infancy. The mandibular halves were separated at birth. Complete fusion had occurred in the majority of infants aged four months, and the tomograms of the remaining infants showed a thin vertical line in a part of the symphysis. The marked changes, which during the first postnatal months occur in the radiographical appearance of the mandibular symphysis, and in the formation of primary teeth, provide valuable information for age assessments of infants. 相似文献

Local context is widely believed to influence voting behavior with, for example, the voters' evaluation of the state of their local economy affecting whether they choose to reward or punish the incumbent government. Such reward-punish models apply in the United Kingdom at the national scale: those who believe that the government has delivered prosperity vote for its return, whereas those who believe that its policies have produced a worsening economic situation vote against it. This article shows that the operation of this calculus varies spatially, according to the level of unemployment in the voter's home area: the higher the local level of unemployment the lower the probability of someone who thought that government polices had delivered national prosperity voting for the incumbent government. It also shows that this is a consequence of cross-pressured situations. Those who thought that the government's policies had delivered both national and local prosperity were very likely to vote for it; those who thought that the policies had delivered national but not local prosperity were less likely to vote for it—especially in areas of high unemployment. 相似文献

Public administration is characterised by a multiplicity of incompatible values. In the 1990s, reformers avoided confronting the inevitable tradeoffs among these values by focusing almost exclusively on the cost‐effective achievement of results. However, older values have a tendency to ‘bite back’ and new ones emerge. In the near term future, public administration will have to deal with at least three sets of values: 1) those that are non‐mission based, and consequently not directly related to achieving results; 2) those that go unprotected when government work is outsourced to private entities; and 3) those associated with globalisation. 相似文献

Abstract: This work investigated the effects of butylscopolamine bromide, a drug present in the pharmaceutical formulation Buscopan® , on the development of Chrysomya megacephala , a blow fly species of considerable forensic and medical importance in Brazil. Larvae exposed to the drug showed a decreased rate of development, with higher drug concentrations further retarding the development. Besides, larvae reared on the presence of the drug showed smaller body weight and body length when compared with larvae reared on the absence of Buscopan® . The drug also affected the mortality of the species. 相似文献

ABSTRACTThe paper deals with research into the innovative provision of public services by the non-governmental organizations in the field of housing. The paper describes the legislation of the housing system in Slovakia and aims to analyse innovation in social housing provision. The paper contributes to the knowledge on innovative social housing solutions provided by non-governmental organizations. The use of cost benefit analysis reveals the benefits of innovation in housing provision by an internationally awarded organization ETP Slovakia. The analysis proves the government´s possible savings of public expenditures if it would decide to support the innovative approach in social housing provision. 相似文献

Legitimacy is a central factor in democratic administrative systems, as it determines the success-or failure-of governance structures. In this article, we search for the sources of legitimacy in metropolitan governance by focusing on governance tiers and mechanisms. Auckland, Dublin, Oslo, and Montreal serve as empirical examples. We highlight the strengths and limitations of different types of metropolitan governance structures, and identify factors that may help to establish long-lasting governance structures. To be legitimate, metropolitan governance must take place at a contextually legitimate administrative level, and the governance mechanisms must be in harmony with a legitimate administrative actor. 相似文献

Tianeptine (Stablon), although structurally similar to tricyclic antidepressants, acts by enhancing the reuptake of serotonin. A fatal case is presented involving a 26-year-old man, found lying in bed with a "mushroom of foam" around his mouth. Empty blister packs of Stablon and a suicide note were found next to the body. A liquid-liquid extraction procedure with n-hexane: ethyl acetate and n-hexane: 2-propanol, followed by LC-DAD-MS analysis, using positive mode electrospray ionization was performed. The detection limit was 0.001 microg/mL. The toxicological results revealed the following tianeptine concentrations in the post-mortem samples: blood 5.1 microg/mL; urine 2.0 microg/mL; liver 23 microg/g; stomach contents 22 mg. Femoral blood analyses also revealed an ethanol concentration of 0.53 g/L. The present method was also developed and validated for the other post-mortem specimens, since no previous published data had confirmed the post-mortem distribution of tianeptine. The absence of other suitable direct causes of death (macroscopic or histological) and the positive results achieved with the toxicological analysis led the pathologist to rule that death was due to an intoxication caused by the suicidal ingestion of tianeptine in combination with alcohol. 相似文献
