Today, preimplantation genetic diagnosis (PGD) has been greatly accepted within the framework of positive law of many European countries. Nevertheless, in other countries, such as Italy, it is forbidden by law. The ruling of the Civil Court of Cagliari which has authorized its use to a Sardinian couple, has opened, in this way, a small crack to be able to asses possible modifications to the Italian regulation on this matter. This article analyses the ruling of the Civil Court of Cagliari (Italy) from an ethical and legal perspective. The criteria which is used to analyse the legitimacy or illegitimacy of the practice of PGD is analysed. That is, on reasons which could justify or not the transfer of embryos in vitro to the woman. With this objective in mind, the Italian and Spanish normative models which regulates this controversial subject are looked at. As a conclusion, a critical evaluation of the arguments presented is made. 相似文献

The role of illicit drugs on driving, and particularly of cannabis and driving, is the object of increasing awareness. While there is increasing evidence of their effect on psychomotor performance and increased risk of involvement in traffic accidents, limited information is available concerning factors that can predict the likelihood of driving under the influence of cannabis. The present study aims to determine the past year prevalence of driving under the influence of cannabis, and of being a passenger in a vehicle driven by a person under the influence of cannabis, as well as to examine the correlations with a broad range of potential risk factors. A total of 2500 people, aged between 14 and 70 and living in Castille and Leon (Spain), were surveyed in 2004 with regard to their consumption of alcohol and illicit drugs. Among those who reported cannabis use in the previous year, further assessment was carried out. 15.7% of those surveyed reported cannabis consumption in the previous 12 months, of whom 9.7% reported driving a vehicle under the influence of cannabis during this period, on average eight times. One out of five (19.9%) reported being a passenger in a vehicle driven by a person under the influence of cannabis, on average five times in the previous 12 months. The predictors of driving under the influence of cannabis were the population size of community, the number of drugs consumed, reference to cannabis-related problems and to being a passenger in a vehicle driven by a person under the influence of alcohol. The data show that cannabis consumption and driving is common, and requires more attention from policy makers. 相似文献

It is increasingly recognized that immigration laws affect immigrants' integration. Most recently there has been growing attention to how immigration enforcement affects families through forced separations caused by deportations and long‐term family separations across national borders stemming from unauthorized entry to the United States. However, beyond enforcement, there has been little systematic account of how other provisions of immigration law contribute to family separations. In this article we examine how four key provisions in immigration law, far from creating conditions for immigrant families to reunite, contribute to keeping families apart. As such, these provisions shape, in fundamental ways, the structure and composition of immigrant families. Relying on data from the American Community Survey and ethnographic interviews in Phoenix, Arizona, we find evidence consistent with the premise that immigration laws affect the formation, composition, and structure of immigrant families with potential long‐term consequences. 相似文献

This article analyzes the marriage boom that took place during the middle decades of the twentieth century. The increase in nuptiality is analyzed in Spain and Sweden from a qualitative perspective, and the authors describe how cultural, social, economic and institutional transformations were understood by women who were in their reproductive period during the marriage boom. In-depth interviews were conducted in both places with 51 women born between 1919 and 1951. The authors argue that it is important that the ways in which the factors previously identified as decisive of the marriage boom are studied for their motivating power, and the way they were or were not made important in people's understandings of their marital practices. The results show that despite the differences between the national contexts of Spain and Sweden, three interrelated themes recurred when the interviewed women framed their marital choices: (1) the normalization of marriage as a life event; (2) religion; (3) and education and work life. The results also suggest that the women highlighted norm systems within which their choices and decisions were made, rather than describing individual choices and decisions as stemming from individual preferences and wishes. 相似文献

We have analysed patterns of alcohol and regular drug consumption by Spanish drivers. Six hundred and seventy five properly completed questionnaires were received from drivers attending three medical traffic centres in Valladolid (Spain) for medical examination prior to obtaining or renewing their driving licence in 1990. Among those surveyed, 24% were 'daily' drinkers and 56.7% were 'weekly' drinkers, the majority (55.5%) being 'light' drinkers (1-39 g/day of pure alcohol). Of those surveyed 28.9% took drugs. The most commonly consumed drugs were analgesics (6.5%), anti-allergic drugs (5.2%) and oral contraceptives (4.6%). Of those drivers taking drugs 28.2% were 'daily' drinkers and 53.8% were 'weekly' drinkers. The study indicates widespread consumption of alcohol and drugs by Spanish drivers. 相似文献

The aim of this study was to analyze the psychometric properties of two instruments that assess attitudes justifying use of aggression in adolescents?? dating relationships: the Attitudes About Aggression in Dating Situations (AADS) and the Justification of Verbal/Coercive Tactics Scale (JVCT). The sample was made up of 2,856 adolescents from different high schools of Madrid. Results supported the three-factor structure for the AADS and the six-factor structure for the JVCT, which was consistent with the theory and with previous research. As expected, the relation between attitudes and aggressive behavior was between small and moderate but significant in most cases. Furthermore, attitudes differed depending on the type of violence, the respondent??s sex, and on whether aggression is carried out by a man or a woman. Finally, the potential applications of these two scales are discussed, and it is concluded that both constitute useful tools to assess justification of aggression in dating relationships in young couples. 相似文献

The aim of this article is to find a correlation between height and femur/skull measurements through Computed Tomography (CT) scans and derive regression equations for total skeletal height estimation in the Caucasian population. We selected 200 Caucasian patients from March 2010 to July 2011 who had to perform a CT scan for cancer restaging. The mean age is 64.5 years. Both sexes are represented by the same number of persons. Patients have executed a total body CT scan with contrast; once scan accomplished, we measured height through a digital scales. We analyzed CT scans of each patient, obtaining multiplanar reconstruction in sagittal and coronal planes with 1mm of thickness, and we measured 10 diameters of skull and femur. Then we performed a single and a multiple regression analysis considering the three diameters that better correlated with height. The skeletal diameters with the highest correlation coefficients with stature were femur lengths, length of cranial base (Ba-N), and distance from the posterior extremity of the cranial base to the inferior point of the nasal bone (Ba-NB). Although both femur and skull are skeletal segments used for stature estimation, in our sample femur gave stronger correlation with height than skull. h=35.7+1.48·BaN+2.32·BaNB+2.53·FEM and h=3.06·FEM+72.6 are the formulae that provided the most accurate stature assessment using multiple and single regression analysis respectively. 相似文献

The combination of knowledge and innovation has become a cornerstone among knowledge and labour intensive enterprises. A growing number of enterprises are defined as knowledge intensive entrepreneurship ventures that have been widely studied in relation to their eco-system. However only few research have addressed this phenomenon to enterprises digital eco-system by adopting mainly a qualitatively approach. We point out that the relevance of the digital eco-system focusing on the role of social networking sites in relationship to innovation and knowledge. The use of social networking sites can provide a wealth of information about individuals and their networks, which can be utilised for various business purposes. It enables enterprises to create online communities and share user-created content. Within this context, enterprises actively interact with external actors such as customers, public institutions, and other businesses to acquire and absorb external knowledge, and then generate innovation. To gain insights from the global economy, 215 small to medium enterprises from different sets of global enterprises, both knowledge-intensive (e.g. management consulting, marketing and advertising, ICT and related services, legal and technical services) and labour-intensive (such as high tech and electronics, food and beverage, and consumer durables), were analysed. Via the Partial Least Square-Path Modelling the relationships between social networking sites, absorptive capacity, and innovation performance were measured. Therefore, recommendations are proffered as to what small-medium enterprises should do in order to enhance their innovativeness. The research ends with conclusions and implications to both scholars and practitioners. 相似文献
