Role of Age and Sex in the Diagnosis of Early-stage Malignant Melanoma: A Cross-Sectional study.

Age and sex have been identified as predictors of outcome in malignant melanoma (MM). This aim of this multicentre, cross-sectional study was to analyse the role of age and sex as explanatory variables for the diagnosis of thin MM. A total of 2430 patients with MM were recruited. Cases of in situ-T1 MM were more frequent than T2-T4 MM (56.26% vs. 43.74%). Breslow thickness increased throughout decades of life (analysis of variance (ANOVA) p < 0.001), with a weak correlation between Breslow thickness and patient's age (r   = 0.202, p < 0.001). Breslow thickness was significantly less in women (1.79 vs. 2.38 mm, p = 0.0001). Binary logistic regression showed a significant (p < 0.001) odds ratio for age 0-29 years (1.18), and 30-59 years (1.16), and for women (1.09). Age and sex explained 3.64% of the variation observed in Tis-T1 frequency (R2 = 0.0364). Age and sex appear to explain a low percentage of the variation in the early detection of MM.

Health-related quality of life assessment in people with multiple sclerosis and their family caregivers. A multicenter study in Catalonia (Southern Europe)

Objectives: To measure the health-related quality of life (HRQoL) of multiple sclerosis (MS) patients and their caregivers, and to assess which factors can best describe HRQoL. Methods: A cross-sectional multicenter study of nine hospitals enrolled MS patients and their caregivers who attended outpatient clinics consecutively. The instruments used were the SF-36 for patients and the SF-12 and GHQ-12 for caregivers. Classification and regression tree analysis was used to analyze the explanatory factors of HRQoL. Results: A total of 705 patients (mean age 40.4 years, median Expanded Disability Status Scale 2.5, 77.8% with relapsing-remitting MS) and 551 caregivers (mean age 45.4 years) participated in the study. MS patients had significantly lower HRQoL than in the general population (physical SF-36: 39.9; 95% confidence interval [CI]: 39.1–40.6; mental SF-36: 44.4; 95% CI: 43.5–45.3). Caregivers also presented lower HRQoL than general population, especially in its mental domain (mental SF-12: 46.4; 95% CI: 45.5–47.3). Moreover, according to GHQ-12, 27% of caregivers presented probable psychological distress. Disability and co-morbidity in patients, and co-morbidity and employment status in caregivers, were the most important explanatory factors of their HRQoL. Conclusions: Not only the HRQoL of patients with MS, but also that of their caregivers, is indeed notably affected. Caregivers’ HRQoL is close to population of chronic illness even that the patients sample has a mild clinical severity and that caregiving role is a usual task in the study context

Networks of PhD Students and Academic Performance: A Comparison across Countries

In this article we compare regression models obtained to predict PhD students’ academic performance in the universities of Girona (Spain) and Slovenia. Explanatory variables are characteristics of PhD student’s research group understood as an egocentered social network, background and attitudinal characteristics of the PhD students and some characteristics of the supervisors. Academic performance was measured by the weighted number of publications. Two web questionnaires were designed, one for PhD students and one for their supervisors and other research group members. Most of the variables were easily comparable across universities due to the careful translation procedure and pre-tests. When direct comparison was notpossible we created comparable indicators. We used a regression model in which the country was introduced as a dummy coded variable including all possible interaction effects. The optimal transformations of the main and interaction variables are discussed. Some differences between Slovenian and Girona universities emerge. Some variables like supervisor’s performance and motivation for autonomy prior to starting the PhD have the same positive effect on the PhD student’s performance in both countries. On the other hand, variables like too close supervision by the supervisor and having children have a negative influence in both countries. However, we find differences between countries when we observe the motivation for research prior to starting the PhD which increases performance in Slovenia but not in Girona. As regards network variables, frequency of supervisor advice increases performance in Slovenia and decreases it in Girona. The negative effect in Girona could be explained by the fact that additional contacts of the PhD student with his/her supervisor might indicate a higher workload in addition to or instead of a better advice about the dissertation. The number of external student’s advice relationships and social support mean contact intensity are not significant in Girona, but they have a negative effect in Slovenia. We might explain the negative effect of external advice relationships in Slovenia by saying that a lot of external advice may actually result from a lack of the more relevant internal advice

Capitalism in the classroom : the impact of self-enhancement values and normative assessment on student motivation, goals and attitudes towards cheating

Abstract The neo-liberal capitalist ideology has come under heavy fire with anecdotal evidence indicating a link between these same values and unethical behavior. Academic institutions reflect social values and act as socializing agents for the young. Can this explain the high and increasing rates of cheating that currently prevail in education? Our first chapter examines the question of whether self-enhancement values of power and açhievement, the individual level equivalent of neo-liberal capitalist values, predict positive attitudes towards cheating. Furthermore, we explore the mediating role of motivational factors. Results of four studies reveal that self-enhancement value endorsement predicts the adoption of performance-approach goals, a relationship mediated by introjected regulation, namely desire for social approval and that self-enhancement value endorsement also predicts the condoning of cheating, a relationship mediated by performance-approach goal adoption. However, self-transcendence values prescribed by a normatively salient source have the potential to reduce the link between self-enhancement value endorsément and attitudes towards cheating. Normative assessment constitutes a key tool used by academic institutions to socialize young people to accept the competitive, meritocratic nature of a sociéty driven by a neo-liberal capitalist ideology. As such, the manifest function of grades is to motivate students to work hard and to buy into the competing ethos. Does normative assessment fulfill these functions? Our second chapter explores the reward-intrinsic motivation question in the context of grading, arguably a high-stakes reward. In two experiments, the relative capacity of graded high performance as compared to the task autonomy experienced in an ungraded task to predict post-task intrinsic motivation is assessed. Results show that whilst the graded task performance predicts post-task appreciation, it fails to predict ongoing motivation. However, perceived autonomy experienced in non-graded condition, predicts both post-task appreciation and ongoing motivation. Our third chapter asks whether normative assessment inspires the spirit of competition in students. Results of three experimental studies reveal that expectation of a grade for a task, compared to no grade, induces greater adoption of performance-avoidance, but not performance-approach, goals. Experiment 3 provides an explanatory mechanism for this, showing that reduced autonomous motivation experienced in previous graded tasks mediates the relationship between grading and adoption of performance avoidance goals in a subsequent task. The above results, when combined, provide evidence as to the deleterious effects of self enhancement values and the associated practice of normative assessment in school on student motivation, goals and ethics. We conclude by using value and motivation theory to explore solutions to this problem.

Social Policy Preferences and Party Choice in the 2011 Swiss Elections

To what extent do social policy preferences explain party choice? This question has received little attention over the past years, because the bulk of the literature has argued that electoral choice is increasingly shaped by identity-based attitudes, rather than by preferences for economic-distributive social policies. We argue that in the wake of this debate, the significance of social policy preferences for electoral choice has been underestimated, because most contributions neglect social policy debates that are specific to post-industrial societies. In particular, they merely focus on income redistribution, while neglecting distributive conflicts around social investment. The Selects 2011 data allows investigating this crucial distinction for Switzerland. Our empirical analyses confirm that it is pivotal to take the pluridimensionality of distributive conflicts seriously: when looking at preferences for social investment rather than income redistribution, we find that social policy preferences are significant explanatory factors for the choice of the five major Swiss political parties.

Les cadres scolaires souhaitent plus d'autonomie qu'ils pensent en avoir : une analyse de la situation en Suisse romande

De manière générale, l'autonomie des établissements de formation influence positivement la performance scolaire. Une enquête réalisée en Suisse romande auprès de 219 cadres scolaires permet, dans la présente contribution, de mesurer l'écart existant entre le degré d'autonomie souhaitée par les cadres scolaires d'une part et le degré d'autonomie dont ils disent disposer d'autre part. Le traitement descriptif des données de l'enquête démontre que, dans tous les domaines de gestion, les cadres scolaires souhaitent disposer de plus d'autonomie qu'ils n'en perçoivent. Ce constat est valable dans tous les cantons, tous les degrés du système éducatif et toutes les fonctions. Le degré d'autonomie souhaitée ne varie que peu selon les cantons, les degrés ou les fonctions. Sur cette base, il n'est pas possible de conclure à la nécessité ou à la pertinence d'un degré d'autonomie différenciée selon les cantons, les degrés ou les fonctions. Le traitement analytique des données de l'enquête identifie les facteurs expliquant l'écart entre les degrés d'autonomie souhaitée et perçue. Cet écart est plus élevé que la moyenne dans les cantons de Fribourg et de Genève, dans le degré primaire et dans la fonction de directeur. En d'autres termes, l'adéquation entre les degrés d'autonomie souhaitée et perçue est moins bonne dans ces cantons, ce degré et cette fonction. Un rattrapage en matière de délégation d'autonomie est dès lors possible. La reconnaissance, à l'intérieur de l'établissement, d'une faculté de conduite et de pilotage à la direction exerce un effet positif sur le degré d'autonomie souhaitée et un effet positif plus important encore sur le degré perçu. Par conséquent, il apparaît qu'une direction dont la faculté de conduite est avérée souhaite non seulement disposer de plus d'autonomie mais parvienne à obtenir (ou à « gagner ») plus d'autonomie. Abstract School autonomy has a positive influence on pupils' performance. This article presents the results of a survey conducted in the French-speaking part of Switzerland on 219 school leaders. The objective of the survey is to measure and to explain the gap between the level of autonomy desired by school leaders, and the level of autonomy that they perceive. Descriptive statistics show that, in every single management area, school leaders wish to have more autonomy than they actually have. This result is valid in all cantons, all levels of the education system and all types of job. The desired level of autonomy varies only slightly depending on the cantons, the levels of the education system and the types of job. On this basis, it is not possible to conclude that it is necessary and relevant to differentiate the level of autonomy depending on the cantons, the levels of the education system and the types of job. Analytical statistics identify the explanatory variables of the gap between the desired level of autonomy and the perceived level of autonomy. This gap is higher than average in the cantons of Fribourg and Geneva, in the primary level of education and in the position of head-teacher. In other words, the adequacy between the desired and the perceived levels of autonomy is worse in these cantons, this level and this position. As a result, a catch-up on the delegation of school autonomy is possible. Results also show that school leaders, whose management competence is recognized by its staff, not only want more autonomy but succeed in securing (or "gaining") more autonomy.

The building blocks of international ecological footprint inequality: a regression-based decomposition

This paper performs an empirical Decomposition of International Inequality in Ecological Footprint in order to quantify to what extent explanatory variables such as a country’s affluence, economic structure, demographic characteristics, climate and technology contributed to international differences in terms of natural resource consumption during the period 1993-2007. We use a Regression-Based Inequality Decomposition approach. As a result, the methodology extends qualitatively the results obtained in standard environmental impact regressions as it comprehends further social dimensions of the Sustainable Development concept, i.e. equity within generations. The results obtained point to prioritizing policies that take into account both future and present generations.

Motivating Employees of the Public Sector: Does Public Service Motivation Matter?

This article analyzes if, and to what extent, the public service motivation (PSM) construct has an added value to explain work motivation in the public sector. In order to address the specificity of PSM when studying work motivation, the theoretical model underlying this empirical study compares PSM with two other explanatory factors: material incentives, such as performance-related pay, and team relations and support, such as recognition by superiors. This theoretical model is then tested with data collected in a national survey of 3,754 civil servants at the Swiss municipal level. Results of a structural equations model clearly show the relevance of PSM. They also provide evidence for the importance of socio-relational motivating factors, whereas material incentives play an anecdotal role.

Le devenir féminin transgenre : une étude qualitative et réflexive sur le genre, la corporéité et la subjectivité sexuelle

RésuméCette thèse en psychologie qualitative et critique de la santé propose un éclairage, sur la subjectivité transgenre, différent des modèles dominants en clinique. Les nosologies de type DSM et de la psychiatrie dominante focalisent sur la seule question de la transition transsexuelle, elles utilisent la sexualité comme outil dans les diagnostics différentiels permettant d'effectuer le gatekeeping de la transition médicalisée du genre. Elles sont décrites comme un dispositif de médicalisation du genre, induisant des pratiques maltraitantes. Une méthodologie qualitative inspirée de la théorie ancrée ainsi que de l'analyse réflexive est utilisée. Un échantillon de 15 personnes représentant la diversité des personnes transgenres FtM a été recruté. Les données provenant d'entrevues non directives sont analysées dans une perspective verticale et horizontale. Les résultats soulignent l'inadéquation des typologies cliniques, de la place qui est donnée à la sexualité dans les procédures diagnostiques et de l'opposition qu'elles construisent entre identité (de genre) et sexualité. Ils plaident pour une vision deleuzienne de type nomade, incarnée et sexuée de la subjectivité transgenre.AbstractThe broad of this study in critical health psychology is to build an understanding of transgender subjectivity which contrast with dominant clinical models. DSM nosology types and dominant psychiatry have traditionally focused only on transsexual transitioning. They use sexuality as a diagnostic tool to address the gatekeeping of the medical transition. These practices have been described as medicalization of gender, inducing mistreatment. A qualitative methodology mixing grounded theory and reflexivity has been used. A sample of 15 persons has been recruited to represent transgender FtM diversity. Data were collected through in-depth interview and analysed case by case and by themes. Results show that dominant clinical typologies of TG are inappropriate, as well as the way sexuality is used in this practices and the opposition between (gender) identity and sexuality. We propose a deleuzian concept of becoming and multiplicity to understand transgender subjectivity.

The post-communist fertility puzzle

Fertility has unanimously declined across the entire post-communist region. This study explores the variation in fertility trends over time among these countries and assesses to what degree three explanations are applicable: second demographic transition (SDT), postponement transition (PPT) or reaction to the economic crisis. Moreover, on the basis of SDT and PPT theoretical tenets, as well as descriptive evidence, the economic context is hypothesized to be linked to two processes of fertility decline conversely. The results show that no one theoretical explanation is sufficient to explain the complex fertility declines across the entire post-communist region from 1990 to 2003. In some countries, a great part of the decline in fertility occurred before significant postponement of childbearing began, which indicates that the dramatic decline was due to stopping behavior or postponement of higher order births. Postponement of first births, either through PPT or SDT processes, greatly contributed to fertility decline in a small number of countries. Pooled cross-sectional time-series analyses of age-specific birthrates confirm that these two distinct processes are present and show that the economic crisis explanation has explanatory power for declining birth rates. In contrast, logistic regressions show that the likelihood of postponing childbirth increases with improved economic conditions. These results confirm the importance of taking the economic context into account when discussing explanations for fertility decline. More specifically, the results indicate that the severity and duration of economic crisis, or absence thereof, influenced the extent and manner in which fertility declined.

The Effect of occupational sex-composition on earnings: job-specialisation, sex-role attitudes and the division of domestic-labour in Spain

Important theoretical controversies remain unresolved in the literatire on occupational sex-segregation and the gender wage-gap. A useful way of summarising these controversies is viewing them as a debate between - cultural -socialisation. The paper discusses these theories in detail and carries out a preliminary test of the relative explanatory performance of some of their most consequential predictions. This is done by drawing on the Spanish sample of the second wave of the European Social Survey, ESS. The empirical analysis of ESS data illustrates the notable analytical pay-offs that can stem from using rich individual-level indicators, but also exemplifies the statistical llimitations generated by small sample size and high rates of non-response. Empirical results should, therefore, be taken as preliminary. They seem to suggest that the effect of occupational sex-segregation on wages could be explicable by workers' sex-role attitutes, their relative input in domestic production and the job-specific human capital requirements of their jobs. Of these three factors, job-specialisation seeems clearly the most important one.

"Il corpo de'pensieri" : la versificazione dei "Canti" leopardiani

L'objet de la thèse est l'étude de l'endecasillabo dans l'oeuvre poétique de Giacomo Leopardi. D'un point de vue méthodologique, ce travail s'appuie sur la recherche de Marco Praloran et Arnaldo Soldani dédiée à l'endecasillabo de Pétrarque. L'auteur a comparé les Canti de Leopardi avec la production des plus grands écrivains de la fin du XIXème siècle et du début du XXème siècle Melchiorre Cesarotti (Poesie di Ossian), Giuseppe Parini (Il Mattino), Vittorio Alfieri (Le Rime e il Saul), Vincenzo Monti (l'ouvre poétique), Ugo Foscolo (Le Rime) et Alessandro Manzoni (l'oeuvre poétique). Nous avons là un répertoire de plusieurs milliers de vers qui ont été scandés non pas par l'intermédiaire d'un ordinateur, mais un à un en fonction de leur intonation. La première partie de la thèse est dédiée à l'analyse du rythme des différents auteurs, à des statistiques générales qui permettent de comparer ces données entre elles et avec les anciens auteurs italiens tels Dante, Pétrarque, Arioste, etc. De cette façon, nous pouvons avoir une vision globale de la prosodie italienne des origines jusqu'au XIXème siècle -vision qui permet de focaliser de manière exhaustive la technique de Leopardi. Dans la deuxième partie, l'auteur propose texte après texte la scansion de toute l'oeuvre poétique de Leopardi. Nous avons donc une lecture interprétative du rythíne de tous les poèmes qui tient compte de l'année de composition et les différentes typologies métriques des textes : par exemple, les canzoni, les idilli, les canti pisano-recanatesi. Dans cette deuxième partie, il faut souligner l'effort de lier la partition du rythme au contenu des différents textes.

As práticas de responsabilidade social organizacional: uma análise nas empresas cabo-verdianas

A responsabilidade social organizacional (RSO) constitui um assunto cada vez mais discutido no seio dos diversos sectores e é considerado importante na gestão das organizações. As acções de responsabilidade social, gradualmente, têm vindo a tornar-se um diferencial em termos de estratégia e competitividade, contribuindo, no seu todo, para a sustentabilidade da sociedade e das pessoas que nela vivem. Assim, torna-se importante compreender a forma como as organizações e seus gestores entendem e assumem o seu compromisso para com todos os stakeholders, bem como despertar-lhes o interesse para os benefícios e vantagens que poderão obter com a prática e implementação de uma gestão da responsabilidade social nas organizações. Apesar de as práticas de RSO constituírem ainda um assunto muito recente em Cabo Verde, já é notável o crescimento das acções desencadeadas pelas organizações em prol de uma sociedade mais justa, responsável e transparente. Com o objectivo de identificar as práticas de responsabilidade social das organizações cabo-verdianas na sua vertente económica, social e ambiental, o presente trabalho inclui uma análise quantitativa e qualitativa, feita a partir da aplicação de um inquérito por questionário, com questões fechadas, complementado por questões abertas. Assim foi realizada uma pesquisa exploratória-descritiva nas organizações, escolhidas em função da sua notoriedade e da sua posição estratégica para o desenvolvimento do país. Entre os principais resultados obtidos pode-se destacar a preocupação com questões ambientais, o respeito pela Lei laboral e apoio regular às comunidades. Dos resultados obtidos e da análise efectuada, pode-se concluir que a cultura da RSO nas organizações cabo-verdianas, ainda se apresenta de forma incipiente. Espera-se, com este trabalho, explicitar o carácter estratégico da responsabilidade social organizacional, bem como fomentar reflexões posteriores de forma a efectivar uma mudança de cultura, levando gestores, colaboradores, e demais stakeholders a desenvolverem o interesse sobre esta matéria, uma vez que a RSO não é apenas um assunto das grandes empresas, mas sim, de todos nós. Social organizational responsibility (SOR) is an increasingly discussed subject amongst several sectors and it’s considered as extremely important on organization management. The social responsibility actions have gradually becoming a disparity regarding strategy and competitivety, contribution in its whole for the society’s and its inhabitant’s sustainability. Thus, it’s important to identify the way the organizations and its managers understand and assume their commitment with the stakeholders, as well as to bring up their interest for the benefits and advantages that they may obtain with the social responsibility management practice on the organizations. Although the SOR practices are still considered as a recent subject in Cape Verde, it’s already noticeable the organizations actions growth towards a fairer, responsible and transparent society. Aiming to identify the capeverdian social organizational responsibility practices on its economical, social and environmental string, this written presentation includes a quantitative and qualitative analysis, with closed questions, completed by open ones. It was therefore performed an explanatory-descriptive research for the organizations, each chosen regarding their notoriety and strategic position for the country’s development. Amongst the main results we may enhance the concern on environmental issues, the respect for the Labour law and the regular support for the communities. From the obtained results and the analysis done, we may conclude that the SOR culture on the Capeverdian organizations is still considered as quite insipient. With this written presentation, it’s expected to explain the social organizational responsibility strategic character, as well as to enhance the posterior reflections in order to implement a cultural change, influencing the managers, co-workers and remaining stakeholders to develop their interest on the subject, once the SOR should not only be some big companies issue, but instead, one regarding all of us.

Bioclimatic constraints to Andean cat distribution: a modelling application for rare species

AimTo identify the bioclimatic niche of the endangered Andean cat (Leopardus jacobita), one of the rarest and least known felids in the world, by developing a species distribution model.LocationSouth America, High Andes and Patagonian steppe. Peru, Bolivia, Chile, Argentina.MethodsWe used 108 Andean cat records to build the models, and 27 to test them, applying the Maxent algorithm to sets of uncorrelated bioclimatic variables from global databases, including elevation. We based our biogeographical interpretations on the examination of the predicted geographic range, the modelled response curves and latitudinal variations in climatic variables associated with the locality data.ResultsSimple bioclimatic models for Andean cats were highly predictive with only 3-4 explanatory variables. The climatic niche of the species was defined by extreme diurnal variations in temperature, cold minimum and moderate maximum temperatures, and aridity, characteristic not only of the Andean highlands but also of the Patagonian steppe. Argentina had the highest representation of suitable climates, and Chile the lowest. The most favourable conditions were centrally located and spanned across international boundaries. Discontinuities in suitable climatic conditions coincided with three biogeographical barriers associated with climatic or topographic transitions.Main conclusionsSimple bioclimatic models can produce useful predictions of suitable climatic conditions for rare species, including major biogeographical constraints. In our study case, these constraints are also known to affect the distribution of other Andean species and the genetic structure of Andean cat populations. We recommend surveys of areas with suitable climates and no Andean cat records, including the corridor connecting two core populations. The inclusion of landscape variables at finer scales, crucially the distribution of Andean cat prey, would contribute to refine our predictions for conservation applications.
