It’s a Beautiful Feeling”: Exploring Embodied, Psychological, and Gendered Motivations for Sex Under the Influence of Cannabis Among Young Adults
Cannabis is the second most used substance in sexual contexts after alcohol, particularly among young adults. Understanding motivations underlying sex under the influence of cannabis can shed light on the needs these practices fulfill, deepening knowledge and providing critical insights for sexual well-being promotion. Moreover, little research has examined how gender shapes these motivations. This study explored motivations for sex under the inf…

Home vs. nursing care: Unpacking the impact on health and well-being
In this paper, we present estimates of the effect of different care settings on health and well- being outcomes. We use data from the French CARE Survey, which interviews individuals aged 60 and above, to assess the differential effect of living at home or in a nursing home on mortality, morbidity and well-being indicators. In addition, we differentiate the effect between for-profit and non-profit nursing homes. To do so, we apply a propensity sc…
The limits of behavioral nudges to increase youth turnout: Experimental evidence from two French elections
There is a significant gap in turnout between young people and older voters. The failure to instill a voting habit at an early age may have long term consequences in terms of future political participation as well as on other civic behaviors. Using a pre-registered online experiment with 3790 subjects, we implemented behavioral interventions aiming to stimulate youth turnout in the 2022 French presidential election. We rely on an innovative incen…

Dilemme du voyageur: Impact comportemental de la valeur du bagage égaré
Cet article a pour objectif, dans le cadre d’une expérience en classe sur le dilemme du voyageur, de montrer l’impact comportemental de la connaissance commune de la valeur des bagages égarés. Cette valeur agit comme un point focal qui canalise le comportement des étudiants dans le rôle des voyageurs. Nous commentons son impact sur le raisonnement des étudiants et sur la structure du jeu. Puis nous construisons un nouveau jeu qui modèle cet impac…

Photography and Semiotics: Use and Purpose
This article looks at photography from the perspective of Charles S. Peirce’s theory of signs. The topic is a mainstay in accounts of photography, though usually it is limited to discussing iconicity and indexicality in a cursive and superficial manner: photos are both likenesses of their objects, and they are existentially determined by them. Yet the practice of photography—the way we use it—requires us to delve deeper into Peirce’s theory of si…

Dis-moi ce que tu penses de la propriété intellectuelle, je te dirai qui tu es »
L’objet de cet article est d’analyser de manière expérimentale les liens supposés entre les préférences sociales des individus et la manière dont ils conçoivent la propriété intellectuelle, en opposant en particulier les approches utilitaristes et déontologiques. Pour ce faire, nous avons mis en place un protocole expérimental original à l’interface de deux courants de littérature : l’un, bien établi, traitant des préférences sociales ; l’autre, …
Poverty and Inequality
This chapter is about the state of inequality and poverty in Europe. We observe differences in poverty rates and income inequality across European countries. At the one extreme, there are the Benelux and Nordic countries with little poverty and small inequalities. At the other extreme, there is a mixed group consisting of Southern, Eastern, and Anglo- Saxon countries. Changes in poverty and inequality over time have been rather small. A number of…
Long-Term Care: Economic and Social Perspectives
This chapter is concerned with the rise in long-term care needs. Long-term care concerns individuals who are no longer able to carry out basic daily activities. Most of the care is currently provided by informal caregivers, mainly the family, while the role of formal care provided by the state or the market remains small. The chapter explains, however, why informal care is expected to decline and analyses the low private insurance development, th…

Mortalité différentielle et pauvreté par âge
En présence d’une mortalité différentielle selon le revenu, les mesures habituelles de la pauvreté ne capturent pas uniquement la vraie pauvreté, mais reflètent également le processus de sélection induit par la mortalité différentielle. Face à ce type de biais de sélection, une solution consiste à étendre, à l’aide d’un revenu fictif, les profils de revenu des personnes décédées prématurément, afin de les prendre en compte dans la mesure de la pa…
The economic geography of institutional investment in the United States, 2010
The economic geography of United States’ institutional investments as of December 2010 is presented. With a self-declared value of almost $13 trillion, it is the largest class of equity investors. Included are all investors who file Securities Exchange Commission (SEC) form 13f, meaning they manage at least $100 million. Analysis is undertaken at both the firm and metropolitan levels. The largest firms and targets of investment are determined. Ge…
Dance and Fetish: Phenomenology and Metz's Epistemological Shift
Christian Metz is remembered today as having almost single-handedly transformed the culture of film studies. This widely held view was summarized by one commentator, who wrote that "with Metz a new research paradigm is born, as well as a new generation of scholars. The ontological theories are followed by methodological theories." According to another, "Metz exemplified a new kind of film theorist, one who came to the field already 'armed' with t…
Social Security and Early Retirement: The Relationship Between Workers, Firms and Governments
In this paper we survey a number of theoretical and empirical studies in order to propose explanations to the fall of labour force participation at older age. Starting from the largely studied effect of social security schemes on labour supply, we explore the employers behaviour and the role of governments in the development of early retirement schemes. We show that early retirement is the result of a global agreement between firms and government…

L'État-providence en Europe: Performance et dumping social
We report an exploratory study examining the interrelationships among common sense, insight into psychosis, and performance on a battery of neuropsychological tests in 32 patients with schizophrenia evaluated at the time of discharge from involuntary hospitalization at a State psychiatric hospital. Common sense, as measured by the Social Knowledge Questionnaire, was associated with better performance across tests measuring parietal lobe functioni…
Measuring poverty without the Mortality Paradox
Peirce's Esthetics: A Taste for Signs in Art
Is Peirce's esthetic relevant for the philosophy of art—what is usually referred to today as aesthetics? At first glance Peirce's idiosyncratic esthetic seems quite unconcerned with issues of art. Yet a careful examination reveals that this is not the case. Thus, rather than attempt to "apply" Peirce's views to some aspect of the practice or the theory of art (e.g., creativity, historiography of art, style, genre), or even to a particular work of…
Conspicuous Consumption: The Figure of the Serial Killer as Cannibal in the Age of Capitalism
The aim of this article is (1) to posit a conceptual model for the way ideas, conceptions, or feelings are represented or 'figured' in memory with the help of the imagination, and (2) to use this model to begin to outline what I believe constitutes part of our culture's 'memory-image' of the serial killer in both fact and fiction. Human memory is not simply a passive storehouse of information. It is an active process whereby relations are created…

ECL I/O buffers for BiCMOS integrated systems: A tutorial overview
In this paper we describe the methodology for the design and layout of fast BiCMOS ECL (emitter-couped logic) I/O buffers. Principles of ECL circuit operation are described with emphasis on the NOR/OR gate and the bandgap voltage reference. A comparison of ECL 10 K and 100 K logic families is presented as well as complete designs for an input and output buffer. The pad macros are temperature- and supply-voltage-compensated and have nominal rise a…
A Sense of Time and Place: The Chronotope in I Confess and Le Confessionnal
A partir de la notion de chronotope elaboree par Mikhail Bakhtine, cet article examine l'inscription du temps et de l'espace dans un film de Robert Lepage, Le Confessionnal, et la compare a celle qui se manifeste dans I Confess d'Alfred Hitchcock egalement tourne dans la ville de Quebec. Si le premier film n'est pas, stricto sensu, un remake du second, il entretient avec lui une relation dialogique et constitue meme une sorte d'appropriation voir…
Remarques sur la sémiotique de l’image
L'A. developpe quelques remarques sur la conception semiologique de l'image figurative, en s'appuyant sur les theories de differents semioticiens, tels que Roland Barthes et Umberto Eco. Il analyse la pertinence des notions d'iconicite et de ressemblance par rapport a l'image dans sa fonction de signe

L’aventure filmologique: Documents et jalons d’une histoire institutionnelle
C’est un décret du 28 octobre 1950 qui crée officiellement l’Institut de filmologie au sein de la Sorbonne, même si, officieusement, les activités de l’Institut — notamment les cours en Sorbonne — remontent à 1948. Le décret de sa fermeture officielle paraît en juin 1963. Que se passe-t-il entre ces deux dates ? Comment naît le premier diplôme universitaire français en études cinématographiques et quelles sont les conditions de la fermeture de l’…
La retraite anticipée des salariés en Belgique
Cet article propose une analyse de la cessation anticipée d’activité des salariés du secteur privé en Belgique. Contrairement aux études précédentes (Pestieau et Stijns [1999] et Dellis et al. [2004]), notre étude se base sur un modèle structurel d’offre de travail. Ceci a l’avantage de pouvoir être utilisé afin de tester l’impact de réformes potentielles visant à augmenter l’activité des plus âgés. Nos résultats montrent qu’il y a une réelle pré…
