Lorenzo Market between Diversity and Mutation

The aim of this paper is to investigate the relationship between the diversity of groups of workers and the local division of labour in the San Lorenzo Market, Florence, Italy. This empirical research may help distinguish the demographic, migratory and occupational patterns of the workers in accordance with their national origin. It shows that geographical origin is the key to the differences, specialisations and oppositions between the Florentines and the various groups of migrants on the one hand, and between these immigrant groups on the other hand. It shows too the mutation made by the conflict between global dynamics and a local labour market.San Lorenzo Market, Immigrant workers, Diversity, Local division of labour, Migratory trajectories

Esplorare un mercato cosmopolita

Cet article rapporte les résultats d'une enquête réalisée en 1999 sur un espace de travail particulier : le Marché San Lorenzo dans le centre-ville touristique de Florence en Italie. Il soulève le problème des rapports socio-professionnels entre d'un côté les travailleurs migrants et les employeurs florentins, et d'un autre côté entre les divers groupes communautaires selon leur temporalité migratoire et leur insertion dans le marché du travail local. Est mise en évidence la substitution du patronat florentin/italien par les Iraniens, et également la diversité et la fluidité des employés migrants.Il contributo qui presentato si fonda su un inchiesta realizzata nel 1999 su uno spazio di lavoro particolare : il Mercato San Lorenzo, nel centro-città di Firenze, Italia. Pone il problema dei rapporti socio-professionali fra da un lato i lavoratori migranti e i padroni fiorentini, e da un altro lato fra i diversi gruppi comunitari a secondo dalla propria temporalità migratoria e inserimento nel mercato locale del lavoro. Evidenzia la sostituzione dei padroni fiorentini/italiani dai Persiani e la fluidità dei comessi migranti

Logiques migratoires et rapports de travail, les travailleurs étrangers dans un espace de travail localisé : le marché touristique de San Lorenzo à Florence, Italie

Influence of previous participation in physical activity on its perceptions among tertiary institution students

Physical inactivity is one of the leading causes of the major non-communicable diseases, which contribute substantially to the global burden of diseases, death and disability. The burden of mortality, morbidity and disability attributable to non-communicable diseases is currently greatest and is continually growing in the developing countries. Most declines in physical activity (PA) occur during the transition period when a person goes from high school to College or University. The objectives of this study were to identify perceived benefits of and barriers to PA and determine whether previous participation in PA does have an influence on these perceptions. A cross- sectional and descriptive study with quantitative design was conducted. Five hundred (500) tertiary institution students were randomly sampled from purposively selected departments and classes at each of the five government educational tertiary institutions in Rwanda. A pre-coded self-administered questionnaire with a small number of open-ended questions was administered to the students. A response rate of 425 (85%) was obtained. Descriptive and inferential statistics were used to analyse the data, by means of SAS version 8 software. Frequencies and percentages for mean score values with standard deviations for each perception variable were descriptively obtained. False Discovery Rate (FDR) at 5% for multiple test adjustment and Spearman’s correlation (r) tests were used to identify the significant influence of previous participation on perceptions. More than 70% students were not participating in PA at tertiary level. Psychological benefits of PA were some of the most important perceived benefits cited by the students. Most of the important barriers cited concerned equipment and time constraints to exercising. Associations were found between previous participation and the current perceptions of PA. The findings of this study demonstrate that previous participation can influence perceptions of PA among the students. Physical activity promotion programmes should consider the role of these factors which should be emphasised from childhood

Automated Analysis of Orthogonal Variability Models Using Constraint Programming.

Software Product Line (SPL) Engineering is about producing a family of products that share commonalities and variabilities. The variability models are used for variability management in SPLs. Currently, the automated analysis of variability models has become an active research area. in this paper we focus on the automated analysis of Orthogonal Variability Model (OVM), which is a modelling language for representing variability. The automated analysis of OVMs deals with the computer-aided extraction of information from OVMs. The automated analysis of OVMs has been hardly explored and currently has no tooling support. Considering our know-how to analyse feature models, which are the most popular variability models in SPLs, we propose to automate the analysis of OVMs by means of constraint programming. in addition, we propose to extend OVMs with attributes, allowing to add extra-functional information to OVMs. With this proposal we contribute with a step forward toward a tooling support for analysing OVMs

Taming the rugged energy landscape: Techniques for the production, reordering, and stabilization of selected cluster inherent structures

We report our studies of the potential energy surface (PES) of selected binary Lennard-Jones clusters. The effect of adding selected impurity atoms to a homogeneous cluster is explored. Inherent structures and transition states are found by combination of conjugate-gradient and eigenvector-following methods while the topography of the PES is mapped with the help of a disconnectivity analysis. We show that we can controllably induce new structures as well as reorder and stabilize existing structures that are characteristic of higher-lying minima.Comment: 9 pages, 9 figures, accepted for publication in J.

Feature Model to Orthogonal Variability Model Transformations. A First Step

Feature Model (FM) and Orthogonal Variability Model (OVM) are both modelling approaches employed to represent variability in software product line engineering. The former is the most popular and it is mainly applied to domain engineering. The later is a more recent approach mainly used to document variability in design and realisation artifacts. in the scenario of interest of our research, which focuses on Application Lifecycle Management environment, it would be useful rely on the FM to OVM transformation. To the best of our knowledge, in the literature, there is no proposal for such transformation. in this paper, we propose an algorithm to transform FM into OVM. This algorithm transforms the variable features of a FM into an OVM, thus providing an explicit view of variability of software product line. When working on these transformation, some issues came to light, such as how to preserve semantics. We discuss some of them and suggest a possible solution to transform FM into OVM by extending OVM

FaMa-OVM: a Tool for the Automated Analysis of Ovms

Orthogonal Variability Model (OVM) is a modelling language for representing variability in Software Product Line Engineering. The automated analysis of OVMs is defined as the computer-aided extraction of information from such models. in this paper, we present FaMa-OVM, which is a pioneer tool for the automated analysis of OVMs. FaMa-OVM is easy to extend or integrate in other tools. It has been developed as part of the FaMa ecosystem enabling the benefits coming from other tools of that ecosystem as FaMaFW and BeTTy
