Advance directives are written or oral statements that are intended to govern healthcare decision-making for their authors, for both positive and negative decisions, should they lose decisional capacity in the future. In a Europe which is facing an ageing population, advance directives play an increasing role to (help) formulate the wishes from elderly patient once they start losing the capacity to decide independently. Advance directives should not only be used as a formulation of the patients' previously made decision, but can also be used as guidelines to better understand the previous expressed wishes of the patient. If the advance directive is formulated in too vague form, the healthcare proxy and/or the healthcare trustee can help the physician interpret the directive. This broader approach towards advance directives is reflected in the case-law of the European Court of Human Rights, as well as on the European legislative level.  相似文献

Victim identification initiatives undertaken in the wake of Mass Fatality Incidents (MFIs) where high-body fragmentation has been sustained are often dependent on DNA typing technologies to complete their mandate. The success of these endeavors is linked to the choice of DNA typing methods and the bioinformatic tools required to make the necessary associations. Several bioinformatic tools were developed to assist with the identification of the victims of the World Trade Center attacks, one of the most complex incidents to date. This report describes one of these tools, the Mass Disaster Kinship Analysis Program (MDKAP), a pair-wise comparison software designed to handle large numbers of complete or partial Short Tandem Repeats (STR) genotypes, and infer identity of, or biological relationships between tested samples. The software performs all functions required to take full advantage of the information content of processed genotypic data sets from large-scale MFIs, including the collapse of victims data sets, remains re-association, virtual genotype generation through gap-filling, parentage trio searching, and a consistency check of reported/inferred biological relationships within families. Although very few WTC victims were genetically related, the software can detect parentage trios from within a victim's genotype data set through a nontriangulated approach that screens all possible parentage trios. All software-inferred relationships from WTC data were confirmed by independent statistical analysis. With a 13 STR loci complement, a fortuitous parentage trio (FPT) involving nonrelated individuals was detected. Additional STR loci would be required to reduce the risk of an FPT going undetected in large-scale MFIs involving related individuals among the victims. Kinship analysis has proven successful in this incident but its continued success in larger scale MFIs is contingent on the use of a sufficient number of STR loci to reduce the risk of undetected FPTs, the use of mtDNA and Y-STRs to confirm parentage and of bioinformatics that can support large-scale comparative genotyping schemes capable of detecting parentage trios from within a group of related victims.  相似文献

Dyadic variability is considered to be a key mechanism in the development of mother-adolescent relationships, and low levels of dyadic flexibility are thought to be associated with behavior and relationship problems. The present observational study examined heterogeneity in the development of dyadic variability in mother-adolescent interactions and associations with psychosocial functioning. Dyadic variability refers to the range of emotional states during interactions of mother-adolescent dyads. During five annual home visits, 92 mother-adolescent dyads (M age T1 = 13; 65.2 % boys) were videotaped while discussing a conflict, and they completed several questionnaires on adolescents’ aggressive behavior and adolescents’ and mothers’ perceived relationship quality. Two types of dyads were distinguished: low variability dyads (52 %) and high decreasing variability dyads (48 %). Over time, high decreasing variability dyads were characterized by a broader emotional repertoire than low variability dyads. Moreover, these two dyad types had distinct developmental patterns of psychosocial adjustment. Over time, high decreasing variability dyads showed lower levels of adolescents’ aggressive behavior, and higher levels of perceived relationship quality than low variability dyads. These findings suggest that over time more dyadic variability is associated with less adjustment problems and a more constructive development of the mother-adolescent relationship. Adaptive interactions seem to be characterized by a wider range of emotional states and mothers should guide adolescents during interactions to express both positive and negative affect. Observing the dyadic variability during mother-adolescent interactions can help clinicians to distinguish adaptive from maladaptive mother-adolescent dyads.  相似文献

This article considers the way in which labour attachment is theorised, both in the 1950s Agricultural Labour Enquiries, and subsequently in the work of Rudra, Bardhan, and Breman. Common to all these texts is a positive conceptualisation of attached labour, and consequently the elimination of its element of unfreedom. Instead, the relation is presented in terms of a materially reciprocal exchange between landholder and worker, a transaction which from the viewpoint of the latter corresponds to a much sought‐after form of job insurance or subsistence guarantee. By contrast, it is suggested here that attachment constitutes de‐proletarianisation undertaken by capital in the course of class struggle, and that in Haryana the agricultural work‐force strongly dislikes this kind of employment.  相似文献

This article considers the fact of and reasons for pre‐ and post‐reform change in the structure of the fiesta system on a rural estate in the province of La Convención, and its effect on the development of a capitalist agriculture. In economic terms, this process involves a transformation of the fiesta from a context in which the landlord extracts rent from his tenants to one in which different peasant strata struggle for control over means of production acquired as a result of the agrarin reform. In politico‐ideological terms, the fiesta operates as an arena where contradictory, non‐religious, and class‐specific idioms of struggle are accepted or rejected by the protagonists.  相似文献

Much of the literature on the ‘land grab’ has thus far focused on the international drivers of foreign agricultural investment, with far less attention paid to the roles of developing country states and domestic political economy in changing forms of agrarian production. This paper analyses how global and domestic processes combine to produce patterns of agrarian transformation in Ethiopia, one of the main targets of foreign agricultural investment. The paper presents a typology of changes in land use and examines in detail three case studies of investments in Ethiopia drawn from this typology. The paper concludes that the most dramatic changes are taking place in lowland, peripheral regions where large-scale, capital-intensive farms employing wage labour pose a serious risk to pastoralists whose ‘use’ of land is contested by the state. Although the government has been careful to avoid mass displacement of settled smallholders, there are also important changes taking place in highland areas, with the government encouraging investments that combine the resources of investors with the labour and land of smallholders. These investments have resulted in exposure to new forms of market risk.  相似文献
