Quand la formation ne suffit pas : la préparation des étudiants à l’emploi en Angleterre,en France et en Suède

The proliferation of internships and the rise of professionalisation in higher education are, in France, frequently condemned as evidence of a quest for greater employability, driven by a skills-based approach. A comparative analysis of the methods used to prepare students for employment shows the degree to which the social mechanisms are homogeneous in England (employability) and in Sweden (bildning). In France, the transition from higher education to employment entails a process of pre-professionalisation. This is characterised by the dominant role of professional skills and their incorporation into the structure of initial education itself. Rather than the outcome of a process of commodification, this mechanism of pre-professionalisation is explained by the persistence of an idealized conception of “matching” that still profoundly marks the relations between education and employment in France.

考虑柔性和间隙的螺旋引纬机构仿真分析

为了提高引纬机构的稳定性和精度,将柔性构件和间隙的影响考虑在内,联合ANSYS和ADAMS建立螺旋引纬机构的刚柔耦合模型,通过ADAMS进行动力学仿真,在刚性系统和刚柔耦合系统中分别分析了旋转铰间隙对剑杆输出特性曲线的影响。在对仿真数据的观察中发现了相当比例的噪声信号,为了消除噪声信号的影响,利用统计学中上下四分位数和中位数来识别替换异常值;在综合考虑间隙和柔性构件的影响时,利用减噪后的加速度曲线与理想刚体系统下的数据的偏差值得到一个新的曲线,该曲线在固定区间内做高频波动,呈现出类似周期性声波信号的特点。结果表明旋转铰间隙是影响剑杆稳定性和精度的主要因素,柔性构件和间隙的综合作用产生了趋向于周期性的碰撞影响。依据研 究结果可以进一步对原刚体模型下设计的引纬机构进行优化设计。     

A new role for Low German? Language insertion as bilingual practice in the process of language shift

This article analyzes language insertion as a bilingual communicative practice, applying a functional, speaker‐focused approach to the study of sociolinguistics and language contact. The article is based on a study of contact phenomena in a formerly diglossic region in Northern Germany, where the previously spoken language – Low German – is in the process of being replaced by the dominant standard variety, German. It examines regional publications in order to establish the linguistic techniques by which Low German elements are incorporated into the Standard German texts and the communicative purposes that they serve. The paper concludes that in the process of language shift an emblematic repertoire from Low German is created which can be applied into the dominant contact language, German, for specific communicative purposes. Ausgehend von einer funktionalen, sprecherzentrierten soziolinguistischen Herangehensweise werden im folgenden Artikel bilinguale Einfügungen als Form mehrsprachiger kommunikativer Praxis untersucht. Die Studie analysiert Kontaktphänomene in einer vormals diglossischen Region Norddeutschlands, in der die gesprochene Sprache Niederdeutsch zunehmend von der dominanten Kontaktsprache Deutsch ersetzt wird. Im Artikel werden regionale Publikationen untersucht, um die sprachlichen Techniken heraus zu arbeiten, mit denen niederdeutsche Elemente in den Text integriert werden und welche kommunikativen Funktionen mit ihnen verbunden sind. Der Artikel kommt zu dem Ergebnis, dass während eines Prozesses von fortschreitendem Sprachverlust ein emblematisches niederdeutsches Repertoire geschaffen wird, das für spezifische Funktionen in die dominante Kontaktsprache Deutsch eingefügt werden kann. [Standard German] In disse Artikel geiht dat um Insprengsels van en Spraak in en anner. De Autor hett unnersöcht un lett weten, dat in Noorddüütskland as en tweetalerge Kuntrei immer mehr de sproken Spraak Nedderdüütsk van de machterge Kuntaktspraak Hoogdüütsk bisieddrückt un oflööst word. Se hett Schrifftstücken ut de Gewesten unnersöcht un deit wiesen, up wat för Maneren nedderdüütske Insprengsels in hoogdüütske Texten inbunnen worden. Daarbi kummt vandag, dat en egenaardig nedderdüütsk Weeswark upkummt, dat bi besünner Gelegenheiden in dat Hoogdüütsk sien Stee kriegen kann. [Low German]     

La motivation,nouvelle inflexion rhétorique dans la mobilisation de la main-d'oeuvre? L'exemple du marché du travail intérimaire en France

L'article pose la question d'une nouvelle inflexion rhétorique dans les régimes de mobilisation et de sélection de la main-d'oeuvre avec le recours systématique à la notion de «motivation» qui semble franchir un palier supplémentaire par rapport aux paradigmes précédents de qualification et de compétence en s'affranchissant totalement de l'idée de «capacités à tenir un poste de travail». Ce changement de paradigme sera interrogé à partir de l'analyse des critères de recrutement utilisés par les entreprises de travail temporaire qui constituent un observatoire privilégié des mutations contemporaines dans les relations d'emploi. Les entreprises de travail temporaire jouent sur le marché du travail un rôle de médiation à l'embauche de plus en plus important, par le biais en particulier d'une externalisation de la gestion des ressources humaines en plein développement. Elles contribuent ce faisant de manière tout aussi conséquente à définir et diffuser des nouvelles normes d’«employabilité».     

Determinants of Vaginal Cleansing,Application, and Insertion in Tete Province,Mozambique, and Products Used

Objective: In this article, we review insertion, application, and cleansing as they include the use of products other than water and have a number of harmful effects. Method: In 2007, a household survey of 919 women carried out in Tete Province, Mozambique, examined 8 vaginal practices. Results: Overall, 10% of the sexually active women reported regularly using these 3 vaginal practices concurrently. Of the women who practiced insertion, 65% used natural substances. A wider variety of products was used for applying substances on the external genitalia and for cleansing purposes. Conclusions: These findings have important implications for future HIV prevention, including in the use of microbicides.

La validation des acquis de l’expérience est-elle un moyen de reconnaissance du travail ?

Based on a survey conducted in 15 firms, associations or occupations where work-based experiences were being validated under the terms of a law that entered the French Labor Code in 2002, questions are raised about this process and its capacity for obtaining more recognition for the work done by wage-earners. After identifying four distinct employer rationales for implementing validation, the channels favoring the obtainment of such recognition are examined when this procedure is actually applied inside firms. Putting one's job into words is a powerful means for making it visible; and the opportunity to face colleagues is an occasion for reinforcing an occupational identity. Nonetheless, validation has little effect on pay, and what is being validated is often ambiguous. Employers’ and wage-earners’ contrasting views reveal how difficult it is to obtain recognition of the work performed. This process has opened the way to changing this in the framework of procedures negotiated, in particular, with labor unions.
