ZASTOSOWANIE DERYWACYJNEJ KONCEPCJI WYKŁADNI PRAWA DO ROZSTRZYGANIA SPRAW ZE STOSOWANIEM PRZEPISÓW UNIJNYCH

Celem artykułu jest przedstawienie aplikacji zastosowania na krajowym poziomie stosowania przepisów unijnych koncepcji wykładni derywacyjnej Macieja Zielińskiego. Podjęto w nim próbę udzielenia odpowiedzi na pytanie o wzajemne relacje przepisów prawnych ustanowionych przez socjologicznie różnych prawodawców do norm postępowania odtwarzanych w procesie wykładni w oparciu o analizę syntaktyczną oraz treściową krajowych i unijnych przepisów prawnych z różnych gałęzi prawa. Zastosowanie założeń koncepcji derywacyjnej do rozstrzygania spraw z elementem unijnym prowadzi do konkluzji, że zarówno zjawisko rozczłonkowania (na poziomie syntaktycznym oraz treściowym), jak również kondensacja norm postępowania w przepisach prawnych przebiegać może w sposób krzyżowy pomiędzy aktami prawnymi ustanowionymi przez różnych prawodawców socjologicznych (faktycznych). Ponadto, analiza szczególnego typu unijnych przepisów bezpośrednio skutecznych, prima facie stanowiących źródło obowiązku normatywnego wyłącznie dla państw członkowskich, w świetle założeń koncepcji wykładni derywacyjnej uświadamia, że przepisy te stanowią w gruncie rzeczy modelową egzemplifikację zjawiska kondensacji elementów norm prawnych. Przeprowadzona analiza relacji zakresowych przepisów prawnych do norm postępowania wykazuje stosowalność koncepcji derywacyjnej w procesie rozstrzygania spraw z elementem unijnym. Koncepcja ta wyjaśnia szczególnie złożone problemy wykładni prawa w sprawach z elementem unijnym oraz dostarcza teorii i praktyce instrumentarium do ich rozwiązywania. Jej zastosowanie unaocznia jednocześnie złożoną strukturę systemu prawa, którą charakteryzuje zjawisko hybrydyzacji.

Combining Textual and Visual Cues for Content-based Image Retrieval on the World Wide Web

Some WWW image engines allow the user to form a query in terms of text keywords. To build the image index, keywords are extracted heuristically from HTML documents containing each image, and/or from the image URL and file headers. Unfortunately, text-based image engines have merely retro-fitted standard SQL database query methods, and it is difficult to include images cues within such a framework. On the other hand, visual statistics (e.g., color histograms) are often insufficient for helping users find desired images in a vast WWW index. By truly unifying textual and visual statistics, one would expect to get better results than either used separately. In this paper, we propose an approach that allows the combination of visual statistics with textual statistics in the vector space representation commonly used in query by image content systems. Text statistics are captured in vector form using latent semantic indexing (LSI). The LSI index for an HTML document is then associated with each of the images contained therein. Visual statistics (e.g., color, orientedness) are also computed for each image. The LSI and visual statistic vectors are then combined into a single index vector that can be used for content-based search of the resulting image database. By using an integrated approach, we are able to take advantage of possible statistical couplings between the topic of the document (latent semantic content) and the contents of images (visual statistics). This allows improved performance in conducting content-based search. This approach has been implemented in a WWW image search engine prototype.

TDM modelling and evaluation of different domain transforms for LSI

Latent semantic indexing (LSI) is a popular technique used in information retrieval (IR) applications. This paper presents a novel evaluation strategy based on the use of image processing tools. The authors evaluate the use of the discrete cosine transform (DCT) and Cohen Daubechies Feauveau 9/7 (CDF 9/7) wavelet transform as a pre-processing step for the singular value decomposition (SVD) step of the LSI system. In addition, the effect of different threshold types on the search results is examined. The results show that accuracy can be increased by applying both transforms as a pre-processing step, with better performance for the hard-threshold function. The choice of the best threshold value is a key factor in the transform process. This paper also describes the most effective structure for the database to facilitate efficient searching in the LSI system.

Understanding the socio-economic distribution of multiple deprivation: An application of self-organising maps

In this paper we seek to contribute to recent efforts to develop and implement multi-dimensional approaches to social exclusion by applying self-organising maps (SOMs) to a set of material deprivation indicators from the Irish component of EU-SILC. The first stage of our analysis involves the identification of sixteen clusters that confirm the multi-dimensional nature of deprivation in contemporary Ireland and the limitations of focusing solely on income. In going beyond this mapping stage, we consider both patterns of socio-economic differentiation in relation to cluster membership and the extent to which such membership contributes to our understanding of economic stress. Our analysis makes clear the continuing importance of traditional forms of stratification relating to factors such as income, social class and housing tenure in accounting for patterns of multiple deprivation. However, it also confirms the role of acute life events and life cycle and location influences. Most importantly, it demonstrates that conclusions relating to the relative impact of different kinds of socio-economic influences are highly dependent on the form of deprivation being considered. Our analysis suggests that debates relating to the extent to which poverty and social exclusion have become individualized should take particular care to distinguish between different kinds of outcomes. Further analysis demonstrates that the SOM approach is considerably more successful than a comparable latent class analysis in identifying those exposed to subjective economic stress.

Economic vulnerability, multidimensional deprivation and social cohesion in an enlarged European community

In this article we have sought to combine regional and social exclusion perspectives on economic exclusion in the enlarged European Community. Our analysis, based on the European Quality of Life Survey, confirms that while the economically vulnerable, identified through latent class analysis, constitute substantially larger groups in the poorer economic clusters, they are much more sharply differentiated from others in the richer clusters. While the economically vulnerable are also disadvantaged in relation to measures of multidimensional deprivation and social cohesion, between economic clusters differences on these dimensions cannot be accounted for by corresponding variations in levels and intensity of economic vulnerability. In fact, the impact of such vulnerability on social cohesion is greater in the more affluent clusters. Copyright © 2005 SAGE Publications.

Beyond the standard work model? Varieties of flexible working time in European economies

Working time has been among the first aspect of the employment relation to be the object of intense regulation at the national and supra-national level. This standard regulation of working time comprised a number of elements: full-time hours, rigid working schedules, strong employers’ control and clear boundaries around working time In spite of general claims about the erosion of this model, few studies have investigated this process in a comparative and empirical perspective. The aim of this paper is to investigate the diversity of working time arrangements in European economies by applying latent class analysis to data
from the European Working Conditions Survey (EWCS). This analysis shows the existence of six different types of working time organization highlighting five cross-national patterns: multiple flexibilities, extended flexibility, standard, rigid and fragmented time.

Overconfidence, sexual health awareness and sexual health risk among young female users of sexual health clinics

This study explored the patterning of young people’s sexual health competence, and how this relates to sexual health outcomes. A survey of 381 young people attending two sexual health clinics in Northern Ireland was carried out between 2009 and 2010. Latent profile analysis of self-rated decision making, self-rated sexual health knowledge, and knowledge of sexually transmitted disease questionnaire scores was used to determine typologies of sexual health competence. Analysis revealed three categories of sexual health competence and explored their association with other behaviours and social characteristics. Young people’s subjective opinion of their sexual health competency, when not matched with a corresponding knowledge of sexual health, could place people at an increased risk of poor sexual health outcomes. Greater levels of peer pressure to have sex and early sexual debut were associated with poorer sexual health knowledge. This finding warrants further investigation, as the importance of self-perceived competence for sexual health screening and education programmes are considerable.

Rapid detection of health-care-associated bloodstream infection in critical care using multipathogen real-time polymerase chain reaction technology: a diagnostic accuracy study and systematic review

Background: There is growing interest in the potential utility of real-time polymerase chain reaction (PCR) in diagnosing bloodstream infection by detecting pathogen deoxyribonucleic acid (DNA) in blood samples within a few hours. SeptiFast (Roche Diagnostics GmBH, Mannheim, Germany) is a multipathogen probe-based system targeting ribosomal DNA sequences of bacteria and fungi. It detects and identifies the commonest pathogens causing bloodstream infection. As background to this study, we report a systematic review of Phase III diagnostic accuracy studies of SeptiFast, which reveals uncertainty about its likely clinical utility based on widespread evidence of deficiencies in study design and reporting with a high risk of bias. 

Objective: Determine the accuracy of SeptiFast real-time PCR for the detection of health-care-associated bloodstream infection, against standard microbiological culture. 

Design: Prospective multicentre Phase III clinical diagnostic accuracy study using the standards for the reporting of diagnostic accuracy studies criteria. 

Setting: Critical care departments within NHS hospitals in the north-west of England. 

Participants: Adult patients requiring blood culture (BC) when developing new signs of systemic inflammation. 

Main outcome measures: SeptiFast real-time PCR results at species/genus level compared with microbiological culture in association with independent adjudication of infection. Metrics of diagnostic accuracy were derived including sensitivity, specificity, likelihood ratios and predictive values, with their 95% confidence intervals (CIs). Latent class analysis was used to explore the diagnostic performance of culture as a reference standard. 

Results: Of 1006 new patient episodes of systemic inflammation in 853 patients, 922 (92%) met the inclusion criteria and provided sufficient information for analysis. Index test assay failure occurred on 69 (7%) occasions. Adult patients had been exposed to a median of 8 days (interquartile range 4–16 days) of hospital care, had high levels of organ support activities and recent antibiotic exposure. SeptiFast real-time PCR, when compared with culture-proven bloodstream infection at species/genus level, had better specificity (85.8%, 95% CI 83.3% to 88.1%) than sensitivity (50%, 95% CI 39.1% to 60.8%). When compared with pooled diagnostic metrics derived from our systematic review, our clinical study revealed lower test accuracy of SeptiFast real-time PCR, mainly as a result of low diagnostic sensitivity. There was a low prevalence of BC-proven pathogens in these patients (9.2%, 95% CI 7.4% to 11.2%) such that the post-test probabilities of both a positive (26.3%, 95% CI 19.8% to 33.7%) and a negative SeptiFast test (5.6%, 95% CI 4.1% to 7.4%) indicate the potential limitations of this technology in the diagnosis of bloodstream infection. However, latent class analysis indicates that BC has a low sensitivity, questioning its relevance as a reference test in this setting. Using this analysis approach, the sensitivity of the SeptiFast test was low but also appeared significantly better than BC. Blood samples identified as positive by either culture or SeptiFast real-time PCR were associated with a high probability (> 95%) of infection, indicating higher diagnostic rule-in utility than was apparent using conventional analyses of diagnostic accuracy. 

Conclusion: SeptiFast real-time PCR on blood samples may have rapid rule-in utility for the diagnosis of health-care-associated bloodstream infection but the lack of sensitivity is a significant limiting factor. Innovations aimed at improved diagnostic sensitivity of real-time PCR in this setting are urgently required. Future work recommendations include technology developments to improve the efficiency of pathogen DNA extraction and the capacity to detect a much broader range of pathogens and drug resistance genes and the application of new statistical approaches able to more reliably assess test performance in situation where the reference standard (e.g. blood culture in the setting of high antimicrobial use) is prone to error.

Clustering of lifestyle risk behaviours among residents of forty deprived neighbourhoods in London: lessons for targeting public health interventions

Background Clustering of lifestyle risk behaviours is very important in predicting premature mortality. Understanding the extent to which risk behaviours are clustered in deprived communities is vital to most effectively target public health interventions. Methods We examined co-occurrence and associations between risk behaviours (smoking, alcohol consumption, poor diet, low physical activity and high sedentary time) reported by adults living in deprived London neighbourhoods. Associations between sociodemographic characteristics and clustered risk behaviours were examined. Latent class analysis was used to identify underlying clustering of behaviours. Results Over 90% of respondents reported at least one risk behaviour. Reporting specific risk behaviours predicted reporting of further risk behaviours. Latent class analyses revealed four underlying classes. Membership of a maximal risk behaviour class was more likely for young, white males who were unable to work. Conclusions Compared with recent national level analysis, there was a weaker relationship between education and clustering of behaviours and a very high prevalence of clustering of risk behaviours in those unable to work. Young, white men who report difficulty managing on income were at high risk of reporting multiple risk behaviours. These groups may be an important target for interventions to reduce premature mortality caused by multiple risk behaviours.

Nonsuicidal Self-Injury and Suicidal Risk: An Examination among Young Adults

Nonsuicidal self-injury (NSSI), which refers to the direct and deliberate destruction of bodily tissue in the absence of suicidal intent, is a serious and widespread mental health concern. Although NSSI has been differentiated from suicidal behavior on the basis of non-lethal intent, research has shown that these two behaviors commonly co-occur. Despite increased research on the link between NSSI and suicidal behavior, however, little attention has been given as to why these two behaviors are associated. My doctoral dissertation specifically addressed this gap in the literature by examining the link between NSSI and several measures of suicidal risk (e.g., suicidal ideation, suicidal attempts, pain tolerance) among a large sample of young adults. The primary goal of my doctoral research was to identify individuals who engaged in NSSI at risk for suicidal ideation and attempts, in an effort to elucidate the processes through which psychosocial risk, NSSI, and suicidal risk may be associated. Participants were drawn from a larger sample of 1153 undergraduate students (70.3% female) at a mid-sized Canadian University. In study one, I examined whether increases in psychosocial risk and suicidal ideation were associated with changes in NSSI engagement over a one year period. Analyses revealed that beginners, relapsed injurers, and persistent injurers were differentiated from recovered injurers and desisters by increases in psychsocial risk and suicidal ideation over time. In study two, I examined whether several NSSI characteristics (e.g., frequency, number of methods) were associated with suicidal risk using latent class analysis. Three subgroups of individuals were identified: 1) an infrequent NSSI/not high risk for suicidal behavior group, 2) a frequent NSSI/not high risk for suicidal behavior group, and 3) a frequent NSSI/high risk for suicidal behavior group. Follow-up analyses indicated that individuals in the frequent NSSI/high risk for suicidal behavior group met the clinical cutoff score for high suicidal risk and reported significantly greater levels of suicidal ideation, attempts, and risk for future suicidal behavior as compared to the other two classes. Class 3 was also differentiated by higher levels of psychosocial risk (e.g., depressive symptoms, social anxiety) relative to the other two classes, as well as a comparison group of non-injuring young adults. Finally, in study three, I examined whether NSSI was associated with pain tolerance in a lab-based task, as tolerance to pain has been shown to be a strong predictor of suicidal risk. Individuals who engaged in NSSI to regulate the need to self-punish, tolerated pain longer than individuals who engaged in NSSI but not to self-punish and a non-injuring comparison group. My findings offer new insight into the associations among psychosocial risk, NSSI, and suicidal risk, and can serve to inform intervention efforts aimed at individuals at high risk for suicidal behavior. More specifically, my findings provide clinicians with several NSSI-specific risk factors (e.g., frequent self-injury, self-injuring alone, self-injuring to self-punish) that may serve as important markers of suicidal risk among individuals engaging in NSSI.

Les représentations sociales du politique: une analyse sémantique de l'idéologie nationale fédéraliste québécoise durant les deux périodes référendaires

Dans ce mémoire, nous proposons l’étude des représentations sociales du politique dans la presse quotidienne. Notre objet d’étude est le sens de la nation au Québec dans une période historique où la notion idéologique de nation s’avère un cadre de référence en profonde mutation dans de nombreuses sociétés. Plus particulièrement, nous voulons nous situer au centre des tensions à propos de la représentation sociale nationale en prenant comme observatoire un travail idéologique fédéraliste par des Québécois, qui à la fois se posent comme promoteurs de la nation, et visent une intégration dans un autre espace national et juridique : le Canada. Les résultats de cette étude qualitative sont issus d’une analyse sémantique du discours éditorial du journal La Presse. Nous avons ainsi examiné les différentes catégories de connaissance mobilisées lors de l’évocation de l’espace national, ainsi que la façon dont elles sont organisées au sein du discours lors des deux périodes référendaires, soit en 1980 et 1995. C’est donc dans le cadre d’une sociologie de la connaissance journalistique que nous menons cette étude. Le discours social, à partir de l’étude des théories des représentations sociales et de la sociologie des contenus médiatiques, ne peut se considérer qu’à travers l’ensemble des relations sociales dont il est le produit. Nous nous attachons ici à définir d’une part les spécificités du discours éditorial, et d’autre part les différentes catégories de connaissances utilisées dans notre corpus qui font sens. On perçoit alors, grâce à une description diachronique, l’évolution des représentations sociales ayant a trait à l’espace national québécois entre les deux périodes étudiées. Après avoir défini ce dont on parle lorsqu’il est question de l’espace national, nous nous emploierons à analyser la façon dont ce discours est organisé. Ainsi, nous mettons en avant d’une part, les différentes formes discursives, rhétoriques et argumentatives, mises en place dans le but de persuader et de justifier l’action (le rejet des deux référendums, et l’adhésion aux promesses de renouvellement du fédéralisme), et d’autre part la logique discursive mobilisée consistant à placer la nation comme un objet politique rationnel ou non. En effet, le discours éditorial nous permet de mettre au jour une organisation cognitive de la connaissance, qui à quelques nuances près, est structurée de façon manichéenne entre le rationnel (l’éditorialiste, le fédéralisme, l’économique, l’universalisme, la raison de sens commun) et l’irrationnel (le souverainisme, ses dirigeants n’étant que des rêveurs et des passionnés), se plaçant dès lors dans un rapport de communication politique, plus proche de la propagande que de l’exemplarité réflexive que pose le discours éditorial.

La comorbidité de l'épuisement professionnel et de la consommation de substances psychoactives.

L’objectif principal du présent mémoire réside dans l’exploration des liens concomitants existant entre les trois dimensions de l’épuisement professionnel telles que définies par Maslach (1981) et la consommation de substances psychoactives, plus précisément au niveau de la consommation épisodique excessive et hebdomadaire à risque d’alcool et de la consommation de médicaments psychotropes. À partir d’un échantillon composé de 1809 travailleurs provenant de 83 milieux de travail québécois, des profils-types correspondant à des formes particulières de comorbidité de santé mentale au travail sont identifiés grâce à la méthode d’analyse en classes latentes. Ainsi quatre profils-types sont dégagés: un premier regroupant les individus dits «sains», dont les scores aux différentes dimensions de l’épuisement professionnel sont faibles et dont la consommation de substances psychoactives est modérée; deux autres correspondant à des formes intermédiaires de risques; et un quatrième rassemblant des travailleurs dits «fragiles» dont les scores pour chacune des dimensions de l’épuisement professionnel se situent dans le quintile le plus élevé et dont les probabilités de consommation de substances psychoactives sont grandes. De plus, cette recherche s’est penchée sur l’identification de facteurs de risque et de protection associés à chacun des profils-types. À cet effet, les résultats des analyses corroborent la plupart des associations retrouvées au sein de la littérature quant aux facteurs du travail (composantes des modèles du stress professionnel de Karasek et Theorell (1990) ainsi que de Siegrist (1990)), hors travail (statut matrimonial, obligations parentales, revenu du ménage) et certaines caractéristiques individuelles (âge et genre). De faibles récompenses et un fort degré de surinvestissement de la part de l’individu se révèlent être des facteurs de risque particulièrement significatifs pour les formes intermédiaires et à risque de comorbidité de la santé mentale au travail. Dans une moindre mesure, une faible utilisation des compétences, des demandes psychologiques élevées, un soutien social inadéquat et le jeune âge expliquent une part de la variation observée entre les différents profils-types. Enfin, les résultats soutiennent une conceptualisation tridimensionnelle de l’épuisement professionnel.
