This paper focuses on the distribution of health care costs among the elderly. Four revenue sources are considered: income taxes, payroll taxes, user fees, and insurance premiums. The empirical work shows that the heavy reliance on direct payments as a means of collecting revenues among the elderly makes their contribution to the health care financing structure more regressive than for the nonelderly. 相似文献

This article discusses young Pakistanis' self-articulation of their relationship with the state, focusing in particular on the perceptions held by those aged between 15 and 25 and who are in education. The research used a mixed methods approach. Data were collected in 6 private, 11 philanthropic and 3 government schools as well as 2 madrassas and 5 universities in urban, semi-urban and rural areas in Punjab, Sindh and Balochistan. A questionnaire with qualitative and quantitative sections was distributed to class 10 students and over 1000 questionnaires were returned. The research found, on aggregate response, that there is a high sense of belonging to the nation, yet paradoxically also a high sense of alienation with regard to the state. Whilst most of those surveyed professed awareness of their rights and duties, the youth was seen by the same respondents as mostly ignorant of these. The factor that caused the greatest variation was the type of school attended where responses and attitudes regarding the state, rights, responsibilities and citizenship differed markedly. This article discusses how this school ‘choice’ is linked with particular perceptions of citizenship by looking beyond class and problematising the relationship between education and the perceptions of the state. 相似文献

Adolescence is a relatively short period between childhood and adulthood. It is very difficult to determine adulthood based on biological indicators. The third molar may be considered a potential age marker for the period between the ages of 16–21. Our study evaluated a set of 1700 panoramic radiographs of individuals aged between 5 and 21 years. Results confirmed the statistically significant difference in the course of third molars development. The mean deviation for individuals with one third molar agenesis is ?0.98 years, for individuals with two third molars agenesis ?1.89 years, and with three molars agenesis ?3.28 years. Thus, the extent of the deviation is directly proportional to the number of unformed third molars. The calculation of age according to the mean of stages of all third molars could lead to the underestimation of age. No intergender differences were found. Age determination using third molars could be used for forensic purposes. 相似文献

Ectodermal dysplasia comprises a group of disorders affecting ectodermal tissues. Severity depends on the genetic aberration; hyperpyrexia secondary to absence of sweat glands is a common complication. Treatment is supportive. This case report describes a 1‐month, 27‐day‐old male infant with a diagnosis of X‐linked recessive anhidrotic ectodermal dysplasia. On the day of his death, his mother swaddled him in a blanket and placed him on the couch at 5:30 am. When she picked him up at 8:00 am, he was unresponsive. At the emergency department, his rectal temperature was 40°C. Postmortem blood culture was positive for group B streptococcus, a possible etiology for fever. It is vital to teach parents that close monitoring of children with ectodermal dysplasia is necessary, as an increase in body temperature can become life threatening. 相似文献

The European Union’s codecision procedure is analyzed as a bargaining game between the Council and the European Parliament. The model shows that the policy outcome is biased towards the ideal point of the institution that is closest to the status quo, when the negotiation leads to an agreement. If the Council’s ideal policy is closer to the status quo, as is the case for example concerning the duration of maternity leave, the resulting policy will remain closer to the Council’s than to the European Parliament’s position. Furthermore, the result of the codecision procedure is Kaldor–Hicks inefficient. The developments of common policies concerning asylum, fishery and maternity leave illustrate both the possibility of the failure of negotiations and the influence of the Council on the outcome. 相似文献

Law firms are knowledge intensive, and the use of advanced technology may well transform these organizations in the future. To examine knowledge management in Norwegian law firms, a study involving four phases of data collection and analysis was designed. The third phase comprised a survey of Norwegian law firms on the use of information technology to support inter-organizational knowledge management. Two predictors, firm co-operation and knowledge co-operation, were significant. The fourth phase was a survey of Norwegian law firms belonging to the Eurojuris network. The Eurojuris law firms had significantly higher IT use, firm co-operation and knowledge co-operation than the other law firms. There was no significant difference in inter-organizational trust, both Eurojuris firms and non-network firms reported that they trusted other law firms. 相似文献
