Building on Bourdieu's reasoning on symbolic capital and distinction, we analyse three interrelated themes. First, we show that alcohol-related variables (drinking patterns, drinking debut, experience of intoxication, etc.) can be used to identify some very distinctive life styles among groups of Danish teenagers. Second, alcohol experience is analysed as a form of symbolic capital among youths, meaning that experience with drinking/partying is decisive for individual teenagers’ position and prestige in the peer group. Third, the article shows that distinction between different drinking patterns is not only a positive phenomenon related to group cohesiveness but also a negative phenomenon related to social dissociation and potential marginalisation of some youngsters. The data used in the article are both quantitative and qualitative. The quantitative data come from a survey with a representative sample of 2000 Danish teenagers aged 15–16 (born in 1989). The qualitative data consist of 28 focus group interviews with teenagers in the eighth and ninth grades in different parts of Denmark.

Es basiert nicht auf einem Testmodell, sondern auf einer strukturierten Testspezifikation die Variabilität beinhaltet. Die Testfälle werden für jede Applikation ermittelt basierend auf dieser Spezifikation. Somit gibt es keine Trennung von Domain- und Application-Engineering zur Wiederverwendung von Tests und Testdaten. Diese Technik zur Ableitung der Testszenarien wird PLUTO genannt und basiert auf der Category-Partition (CP) Methode. Diese Methode wird auf die hier auch vorgestellten PLUCs = Product Line Use Cases angewendet. Category Partioning ist ein dynamisches Blackbox-Test-Verfahren und basiert auf der Idee, die Testdaten in Kategorien zu unterteilen. Zuerst werden die Parameter der zu testenden Methode identifiziert. Im Anschluss werden die für den Test relevanten Aspekte aufgestellt. Auf diese Weise haben wir unsere Menge von möglichen Eingabedaten in Kategorien aufgeteilt. Es fällt uns nun leichter mögliche Eingabedaten für unseren Test zu finden, da wir nun jede Kategorie einzeln betrachten können und so schneller zu unseren Choices (den Teilmengen möglicher Eingabewerte einer bestimmten Kategorie) kommen. Weil der Ansatz auf Requirements basiert, die zwar strukturiert sind, aber in natürlicher Sprache verfasst sind, ist es ein halb-automatischer, halb-manueller Ansatz. Für IST-SPL wäre zu überlegen, ob die Category-Partition, oder die diese Methode erweiternde Klassifikationsbaummethode auf ScenTED zu übertragen wäre um die Testdaten und ergebnisse zu bestimmen. Z.B. wäre es möglich die Aktivitätsdiagramme mittels OCL zu erweitern und dann daraus mittels der Klassifikationsbaummethode automatisch Testdaten ableiten???425--445Product Line Use Cases: Scenario-Based Specification and Testing of Requirements2006PLUTO cases PLUC requirements product use specification testing scenario-based line Tue Apr 29 08:06:25 CEST 2008Journal of Multinational Financial ManagementJul3193--215Can the use of foreign currency derivatives explain variations in foreign exchange exposure?: Evidence from Australian companies132003use derivative currency Foreign Mon Apr 28 13:05:01 CEST 2008European Economic ReviewJan129--53Routine492005use Time Mon Apr 28 13:05:01 CEST 2008Journal of Public EconomicsMay2289--315State alcohol policies, teen drinking and traffic fatalities721999Alcohol use 01Tue Apr 08 12:45:51 CEST 2008Edinburgh, ScotlandProceedings of the Collaborative Web Tagging Workshop at the WWW 2006May{Position Paper, Tagging, Taxonomy, Flickr, Article, ToRead}2006toread use folksonomy In recent years, tagging systems have become increasingly popular. These systems enable users to add keywords (i.e., �tags�) to Internet resources (e.g., web pages, images, videos) without relying on a controlled vocabulary. Tagging systems have the potential to improve search, spam detection, reputation systems, and personal organization while introducing new modalities of social communication and opportunities for data mining. This potential is largely due to the social structure that underlies many of the current systems. Despite the rapid expansion of applications that support tagging of resources, tagging systems are still not well studied or understood. In this paper, we provide a short description of the academic related work to date. We offer a model of tagging systems, specifically in the context of web-based systems, to help us illustrate the possible benefits of these tools. Since many such systems already exist, we provide a taxonomy of tagging systems to help inform their analysis and design, and thus enable researchers to frame and compare evidence for the sustainability of such systems. We also provide a simple taxonomy of incentives and contribution models to inform potential evaluative frameworks. While this work does not present comprehensive empirical results, we present a preliminary study of the photosharing and tagging system Flickr to demonstrate our model and explore some of the issues in one sample system. This analysis helps us outline and motivate possible future directions of research in tagging systems.Tue Apr 08 09:35:40 CEST 2008Selected Papers from the International Semantic Web Conference, International Semantic Web Conference (ISWC2005)Web Semantics: Science, Services and Agents on the World Wide WebMarch15--15Ontologies are us: A unified model of social networks and semantics52007toread use semantics In our work the traditional bipartite model of ontologies is extended with the social dimension, leading to a tripartite model of actors, concepts and instances. We demonstrate the application of this representation by showing how community-based semantics emerges from this model through a process of graph transformation. We illustrate ontology emergence by two case studies, an analysis of a large scale folksonomy system and a novel method for the extraction of community-based ontologies from Web pages.Mon Apr 07 10:14:08 CEST 2008Ontology of Folksonomy: A Mash-up of Apples and Oranges2005read folksonomy generation ontology use Abstract: Ontologies are enabling technology for the Semantic Web. They are a means for people to state what they mean by formal terms used in data that they might generate or consume. Folksonomies are an emergent phenomenon of the social web. They are created as people associate terms with content that they generate or consume. Recently the two ideas have been put into opposition, as if they were right and left poles of a political spectrum. This piece is an attempt to shed some cool light on the subject, and to preview some new work that applies the two ideas together to enable an Internet ecology for folksonomies.Mon Apr 07 10:14:08 CEST 2008ISWC/ASWCconf/semweb/2007touse367--380Lecture Notes in Computer ScienceWeb Search Personalization Via Social Bookmarking and Tagging.48252007use folksonomy read Abstract. In this paper, we present a new approach to web search per- sonalization based on user collaboration and sharing of information about web documents. The proposed personalization technique separates data collection and user profiling from the information system whose contents and indexed documents are being searched for, i.e. the search engines, and uses social bookmarking and tagging to re-rank web search results. It is independent of the search engine being used, so users are free to choose the one they prefer, even if their favorite search engine does not natively support personalization. We show how to design and implement such a system in practice and investigate its feasibility and usefulness with large sets of real-word data and a user study.Thu Nov 22 17:17:23 CET 2007International Journal of Industrial Ergonomics#may#5429--444The effects of speed and force of keyboard operation on neck-shoulder muscle activities in symptomatic and asymptomatic office workers352005Office Work-related Motor limb control Computer ergonomics upper stressors Physical and use neck disorders Electromyography The study compared the EMG changes and discomforts experienced by a symptomatic and an asymptomatic group of office workers when they were challenged by the physical stressors of increased typing speed and increased typing force. 21 female office workers were recruited in the Case Group and 20 in the Control Group. Each subject had to perform 20 min of typing in 3 conditions: Normal, Faster and Harder; which described the requirement to work with normal speed and force, faster speed and harder force, respectively. The Case Group showed trends for higher muscle activities in all three conditions in both the upper trapezius and cervical erector spinae muscles. On the whole, there were greater increases in muscle activities in both groups under the Faster condition, implying that increasing the typing speed was a more difficult demand. When the Case subjects were sub-divided into High and Low (Discomfort) Groups, greater differences in muscle activities were revealed. It was mainly the High Group that showed the greatest changes in terms of muscle activities and discomforts. The Low Group showed moderate increases in discomforts and muscle activities, while the Control Group showed minimal changes in both. The results supported the "Altered Motor Control" model in the symptomatic individuals who may also have developed a "heightened sensitivity" to physical stressors due to their prolonged history of discomforts in the past.Relevance to industry The study demonstrated different reactions of symptomatic and asymptomatic office workers when they were subjected to the same physical stressors. These inter-individual differences in physiological and psychological responses should be considered when ergonomic interventions are introduced. The results also demonstrated that the factors of speed and force of keyboard operation may have important influences on the muscle activities and discomforts in computer users.Wed Nov 21 16:13:12 CET 2007Communications of the ACM8142--151Automatic personalization based on Web usage mining432000profile datamining usage mining use proj:mh proj:bk personalization Wed Nov 21 16:12:33 CET 2007SIGKDD Explorations212--23Web usage mining: discovery and application of usage patterns from web data12000web use mining proj:mh profile profiling usage proj:bk Wed Jun 20 11:07:20 CEST 2007Applied Economics6681-688Violent crime: a function of drug use or drug enforcement?322000crime violent drugs enforcment police drug law use An assumption of many national drug control policies is the existence of a causal relationship between illegal drug use and violent crime. However, robust empirical findings supporting this relationship are scarce. Alternatively, there is extensive research, much of it in economics, which suggests that there may actually be a stronger causal relationship between drug enforcement/control/prohibition and violent crime than drug use and criminal violence. The paper presents some of the research pertaining to the relationship between illegal drugs and violent crime. In addition, a violent crime model is empirically tested using data from 24 Metropolitan Statistical Areas (MSAs) in the United States to determine the nature and strength of this relationship.Fri Oct 27 21:48:59 CEST 2006Dissertation-Abstracts-International:-Section-B:-The-Sciences-and-EngineeringUM: AAINQ41605; MT: Print; FO: Print; PO: Human; AG: Adulthood (18-yrs-and-older); MD: Empirical-Study9-B4869Evaluation of a self-instructional manual for the Assessment of Basic Learning Abilities test602000for abilities basic of test Personnel Manual; direct care how instruction disability Psychological providers; to use developmental Health assessment Individualized Self with service learning individuals Direct-care service providers offering programs to individuals with developmental disabilities face a daily challenge in selecting training and work tasks that are appropriate for the abilities of the clients. An assessment tool that has considerable predictive validity for selecting such tasks is the Assessment of Basic Learning Abilities test (ABLA: Kerr, Meyerson, & Flora, 1977). Thus far, however, research and applications using the ABLA test have been conducted largely by graduate students. The purpose of this research was to investigate the efficacy of a Self-Instructional Manual (SI-M) for teaching direct-care service providers to use the ABLA test for assessing individuals with developmental disabilities, and for analyzing training tasks according to the highest ABLA levels that clients must pass in order to learn such tasks readily. The research included four progressive studies to assess an SI-M for the ABLA test. The results demonstrated that, after studying the SI-M and practising with a partner for approximately six hours, direct-care service providers met mastery criteria for knowledge of the ABLA, applying the test to assess clients, and classifying training and work tasks according to the highest level of the ABLA needed to perform them. Moreover, the SI-M was considerably more effective in accomplishing these tasks than was the original description of the ABLA test.

Prostaglandin E inhibits the functions of T lymphocytes which are involved in the pathophysiology of cluster headache. Therefore, a double-blind, placebo-controlled, crossover study on the efficacy of misoprostol in chronic refractory cluster headache was performed. Eight patients were treated with 600 micrograms misoprostol and with placebo for a 2-week period. No differences in attack frequency, intensity, global impression, and side effects could be detected, suggesting that prostaglandin E analogs are not effective in the treatment of chronic cluster headache.Tue May 30 01:06:19 CEST 2006CephalalgiaJun5619-22Cluster headache after dental extraction: implications for the pathogenesis of cluster headache?212001use & Prednisolone/administration Aged Fibers Tooth Channel Period Blockers/administration Therapy Verapamil/administration Postoperative AND Middle Extraction/*adverse Anti-Inflammatory Combination Molar, therapy Molar/innervation dosage Nerve Male Lithium Causalgia/drug effects Calcium Hypothalamus/physiopathology Cluster Agents/administration Third/innervation Female Headache/drug neuroscience Trigeminal Oxygen/therapeutic Humans Nerve/*injuries Respiratory Therapy, Carbonate/administration Drug useCommunity for tag(s) use
