Identity and academic motivation are particularly at stake before the major transition to higher education. However, few studies have explored their changes and their longitudinal bidirectional links. To fill this gap, a three-wave study from the end of the 11th grade to the end of the 12th grade was conducted to explore changes in identity processes and academic motivation and to investigate how they might be interconnected over time. 599 adolescents (mean age 17.4; 59% girls) completed questionnaires containing measures about identity processes and three types of academic motivation: autonomous, controlled, and impersonal. Throughout the study span of one year, four identity processes increased: commitment making, identification with commitment, exploration in breadth and exploration in depth, while the process of ruminative exploration decreased. Simultaneously, late adolescents encountered an increase in impersonal motivation, more salient for boys. The results also revealed unidirectional links from motivation to identity processes, with no gender or age moderator effects: exploration in breadth and exploration in depth were positively predicted by autonomous motivation, ruminative exploration was positively predicted by autonomous, controlled, and impersonal motivation. In addition, impersonal motivation negatively predicted commitment making. On the other hand, identification with commitment positively predicted autonomous motivation. Practical implications are discussed.

Today, a large majority of states allow at least some of their emigrants to take part in home country elections from abroad. This article first looks at the diffusion of external voting laws and shows that over the past 25 years they have become widely-adopted and are no longer limited to specific professional categories of citizens. Second, the article explains the international diffusion of external voting by discussing the “norm-internationalization hypothesis” and the “electoral-competition hypothesis.” Third, the article attempts to demonstrate that these hypotheses cannot explain why, in a democratic context, states continue to implement a series of hurdles that deter emigrants from using their newly gained rights. Looking at recent developments in Latin America and the Middle East and North Africa, it concludes that the diffusion and variations of external voting laws result from transnational negotiation processes in a context of democratic transformation among various actors whose interests are strongly affected by the inclusion or exclusion of these new voters.  相似文献

We analyze the European institutional integration that took place in the 1950s and 1960s as a two-stage process. Firstly, an explicitly political project aims at establishing a European political community. The project is abandoned in the mid-1950s and political integration stops. At that time, the institutions of the Union take the form of a confederation. In a second stage, because of the failure of the European political community, a legal process of integration driven by the European Court of Justice takes place. This second stage of unification is more centralizing and in effect leads to a federalization of the European institutional structure. The transformation of the political structure of the European Union thus appears to result from the actions and decisions of a legal entity, the European Court of Justice.   相似文献

Acute promyelocytic leukemia (APL) is a subtype of acute myelogenous leukemia frequently associated with clotting abnormalities and severe hemorrhagic diathesis. The disease is associated with a high incidence of early fatal hemorrhage. We report the sudden death of a 40-year-old male without significant medical history in which foul play had been initially suspected. A thorough postmortem investigation performed on the decedent lead to the diagnosis of APL. Cause of death was a cerebellar hematoma. Underlying APL should be considered in the differential diagnosis when unexplained bleeding is encountered in a decedent. This case emphasizes the value of routinely collecting bone marrow during an autopsy to enable accurate testing and diagnosis.  相似文献

The allele frequency distribution of 15 short tandem repeats (STR) loci contained in the AmpFlSTR Identifiler PCR Amplification Kit (Applied Biosystems), was determined in two Berber populations from Asni and Bouhria, in Central and Eastern Morocco, respectively. A total of 209 individuals were typed. No deviations from the Hardy-Weinberg equilibrium were observed for Asni at the 15 STRs loci whereas for the Bouhria samples, two loci (D5S818 and TH01) showed significant departures from Hardy-Weinberg expectations (after Bonferroni's correction). All loci are highly polymorphic and population differentiation tests showed that the Moroccan samples from Asni and Bouhria have significant differences in 4 out of 15 loci (D21S11, D7S820, D16S539 and TPOX). The aim of the study was to obtain accurate allele frequencies relevant for forensic applications. Comparative analyses between our population data and other population samples gathered from the literature are also presented.  相似文献

After a drug-facilitated sexual assault (DFSA), a woman was found in a drowsy state at home. She remembered having drunk an unknown beverage by the accused. Blood samples (collected 8 hours after the DFSA), two glasses, and a teaspoon seized by the police were analyzed. Acepromazine, a phenothiazine tranquilizer used in human and veterinary medicine, was detected in the residue of one of the glasses. In spite of acepromazine absence in the victim's blood, the possible use of acepromazine in the DFSA was reported to the police. Two weeks later, a suspect admitted having orally administered acepromazine to the victim. Using a liquid chromatography-tandem mass spectrometry method, this compound was subsequently detected (31 pg/mg) in a sample of the victim's hair collected a month and a half after the DFSA. A potential short elimination half-life in humans and/or the well-known in vitro degradation of acepromazine could explain the negative blood result. DFSA toxicological investigations are challenging and can be complicated when a rather unusual substance is concerned. In particular, special care should be taken when interpreting the results, taking into account elimination and/or instability data, when available.  相似文献

The framework of public decisions, and particularly the provision of law, is seen here as an agency contract. What distinguishes this contract is the nature of the right delegated to the agent: The capacity to make law gives the opportunity to take advantage of the incompleteness of the constitutional contract. The agency relationship may be loosened or even reversed. This article tries to draw some lessons from the English and American history in that matter and applies them to the making of the future European State.  相似文献

The code Napoleon has been one of the first (on such a scale), the most important and the most pervasive processes of codification that ever took place. The purpose of our paper is to provide an economic analysis of the making of this codification. We compare customary codification and contractual codification: while the former amounts to the crystallisation of socially accepted practices, the latter consists in a creation of rules through a writing process. These theoretical differences are less clear-cut when history mixes practices and reasoned arguments. We then show that the making of the code Napoleon reflects it since it borrows from the social contract and the spontaneous order traditions.  相似文献
