Everyday tragedy and creation: Translated from the French by Karen Isabel Ocaña

In this essay, Michel Maffesoli exalts the poetry of the everyday, and a way of being that, paradoxically, opens one up to life through rituals that smack of a quest for divine nothingness. ‘Everyday Tragedy and Creation’ traces a series of connections: between Benjamin’s particular form of empirical mysticism and the notion of messianic time, the vitalism of Nietzsche (and tangentially his rediscovery of the Greek notion of tragedy and destiny), that of Bergson with his concept of duration, as well as the sociological hermeneutics of Dilthey. In the course of his discussion, Maffesoli invokes Verlaine, Rimbaud, street theatre and Eliot, and proposes a Zen-like approach to everyday happiness. More generally, Maffesoli rejects the temporality of modernism and drama and celebrates instead the ‘non-time’ of the tragedy of living in the present within a medium of communal images and practices.     

Adolescents,Online Marketing and Privacy: Predicting Adolescents’ Willingness to Disclose Personal Information for Marketing Purposes

The present study aims at exploring which factors predict the willingness of adolescents to disclose personal information in response to online marketing requests. Our analyses show that especially privacy concerns and perceived benefits explain a considerable portion of variance in both willingness to disclose profile data (e.g. age, hobbies, favourite products) and contact data (e.g. phone number, e‐mail address, home address). An interesting interrelationship was found between profile data and contact data disclosure. Contrary to our expectations, parental mediation strategies were only a weak predictor of teenagers’ willingness to disclose contact information. Policy implications that emerge from the central findings of this study are discussed.     

Diversity of romantic experiences in late adolescence and their contribution to identity formation

Romance constitutes a central experience in adolescence, which can take several forms including (a) serious romance with a steady partner, (b) casual and short‐lived dating, and (c) pending experiences of romantic thoughts and attempts. Using a three‐way longitudinal design, the present study examined the gender differences and developmental changes of these romantic experiences, and their cross‐lagged associations with identity processes, throughout one year in late adolescence. 389 students (63% girls) filled out questionnaires about their romantic experiences and identity processes. Girls reported more serious romance than did boys, who reported more casual dating and pending experiences. Serious romance increased over the year for both genders whereas casual dating and pending experiences continued to rise only for boys. The cross‐lagged model highlighted that serious romantic experience positively predicted identity commitments and exploration in depth whereas identity exploration in breadth positively predicted casual dating. This pattern was stable over the three time points and across gender and age groups. Overall, this study invites consideration of more diverse romantic experiences than those associated with tangible involvement. We discuss the contribution of romantic experiences to the identity dynamic.

Modelling and controlling product manufacturing systems using bond-graphs and state equations: Continuous systems and discrete systems which can be represented by continuous models

This paper presents an approach to the modelling and control phases involved in a cooperative process of design and management of the manufacturing systems. Modelling the evolution of the production flow, in the different sections of the system, is based upon the use of the bondgraph methodology in order to reach the state formalism which constitutes one of the modern representations of automation. The class of the systems studied ranges from continuous systems to discrete systems, which can be represented by a continuous approach according to the level of approximation required. The first part of this paper is dedicated to the development of generic models associated with the various basic entities of the manufacturing systems. Then, the bondgraph model of any system is obtained by assembling generic models in relation to the implementation of the means of the studied system, thus guaranteeing a representation which is quite close to the engineering sketches. Finally, switching to the state equation is performed systematically with the easiness provided by this formalism while taking into account the causality principle. An application, involving most of the elementary models developed, concludes the paper.     

Risk aversion in expected intertemporal discounted utilities bandit problems

We consider a situation where an individual is facing an uncertain situation, but may costly alter his knowledge of the uncertainties. We study in this context how risk aversion may modify the individual search behavior. We consider a one-armed bandit problem (where one arm is safe and the other is risky) and study how the agent risk aversion can change the sequence of arms selected. The main result is that when the utility function is more concave, the agent has more chances to select the safe arm. We also discuss how search is affected by risk aversion.     

Three Lenses on Occupations and Professions in Organizations: Becoming,Doing, and Relating

Management and organizational scholarship is overdue for a reappraisal of occupations and professions as well as a critical review of past and current work on the topic. Indeed, the field has largely failed to keep pace with the rising salience of occupational and professional (as opposed to organizational) dynamics in work life. Moreover, not only is there a dearth of studies that explicitly take occupational or professional categories into account, but there is also an absence of a shared analytical framework for understanding what occupations and professions entail. Our goal is therefore two-fold: first, to offer guidance to scholars less familiar with this terrain who encounter occupational or professional dynamics in their own inquiries and, second, to introduce a three-part framework for conceptualizing occupations and professions to help guide future inquiries. We suggest that occupations and professions can be understood through lenses of “becoming”, “doing”, and “relating”. We develop this framework as we review past literature and discuss the implications of each approach for future research and, more broadly, for the field of management and organizational theory.     

Machine Learning Methods as a Tool for Predicting Risk of Illness Applying Next‐Generation Sequencing Data

Next‐generation sequencing (NGS) data present an untapped potential to improve microbial risk assessment (MRA) through increased specificity and redefinition of the hazard. Most of the MRA models do not account for differences in survivability and virulence among strains. The potential of machine learning algorithms for predicting the risk/health burden at the population level while inputting large and complex NGS data was explored with Listeria monocytogenes as a case study. Listeria data consisted of a percentage similarity matrix from genome assemblies of 38 and 207 strains of clinical and food origin, respectively. Basic Local Alignment (BLAST) was used to align the assemblies against a database of 136 virulence and stress resistance genes. The outcome variable was frequency of illness, which is the percentage of reported cases associated with each strain. These frequency data were discretized into seven ordinal outcome categories and used for supervised machine learning and model selection from five ensemble algorithms. There was no significant difference in accuracy between the models, and support vector machine with linear kernel was chosen for further inference (accuracy of 89% [95% CI: 68%, 97%]). The virulence genes FAM002725, FAM002728, FAM002729, InlF, InlJ, Inlk, IisY, IisD, IisX, IisH, IisB, lmo2026, and FAM003296 were important predictors of higher frequency of illness. InlF was uniquely truncated in the sequence type 121 strains. Most important risk predictor genes occurred at highest prevalence among strains from ready‐to‐eat, dairy, and composite foods. We foresee that the findings and approaches described offer the potential for rethinking the current approaches in MRA.     

Relations between Theory of Mind and Indirect and Physical Aggression in Kindergarten: Evidence of the Moderating Role of Prosocial Behaviors

The present study examined the association between theory of mind and indirect versus physical aggression, as well as the potential moderating role of prosocial behavior in this context. Participants were 399 twins and singletons drawn from two longitudinal studies in Canada. At five years of age, children completed a theory of mind task and a receptive vocabulary task. A year later, teachers evaluated children's indirect and physical aggression and prosocial behavior. Indirect aggression was significantly and positively associated with theory of mind skills, but only in children with average or low levels of prosocial behavior. Physical aggression was negatively associated with prosocial behavior but not with theory of mind. Each analysis included gender, receptive vocabulary, and the respective other subtype of aggression as control variables. These results did not differ between girls and boys or between twins and singletons. Theoretical and clinical implications of these findings are discussed.
