Entzug als Endlosschleife?: die Rolle von Sozialarbeitern und Sozialarbeiterinnen bei Entstehung und Vermeidung emotionaler Abhängigkeiten im SuchthilfekontextDietze, Claudia 26 January 2024 (has links)
Die Masterarbeit beleuchtet die Entstehung emotionaler Abhängigkeitsverhältnisse zwischen Fachkräften der Sozialen Arbeit im Bereich der Suchtkrankenhilfe und ihren Adressaten. Besonders im Suchthilfebereich sind (anderweitige) Abhängigkeiten als höchst vulnerabel anzusehen, da sie das „Prinzip“ Hilfe zur Selbsthilfe massiv stören und den „Suchtkreislauf“ nicht durchbrechen, sondern (auf anderer Ebene) erhalten können.
Ziel der Arbeit ist es, durch Befragung von Fachkräften in unterschiedlichen Einrichtungen das professionsbezogene Bewusstsein menschlicher und kontextueller Abhängigkeiten zu ergründen und Perspektiven wie Möglichkeiten zu sammeln, wie diese Abhängigkeitsverhältnisse abgebaut oder verhindert werden können.:Vorwort 2

Managing Service Dependencies in Service CompositionsWinkler, Matthias 21 December 2010 (has links) (PDF)
In the Internet of Services (IoS) providers and consumers of services engage in business interactions on service marketplaces. Provisioning and consumption of services are regulated by service level agreements (SLA), which are negotiated between providers and consumers. Trading composite services requires the providers to manage the SLAs that are negotiated with the providers of atomic services and the consumers of the composition. The management of SLAs involves the negotiation and renegotiation of SLAs as well as their monitoring during service provisioning. The complexity of this task arises due to the fact that dependencies exist between the different services in a composition. Dependencies between services occur because the complex task of a composition is distributed between atomic services. Thus, the successful provisioning of the composite service depends on its atomic building blocks. At the same time, atomic services depend on other atomic services, e.g. because of data or resource requirements, or time relationships. These dependencies need to be considered for the management of composite service SLAs.
This thesis aims at developing a management approach for dependencies between services in service compositions to support SLA management. Information about service dependencies is not explicitly available. Instead it is implicitly contained in the workflow description of a composite service, the negotiated SLAs of the composite service, and as application domain knowledge of experts, which makes the handling of this information more complex. Thus, the dependency management approach needs to capture this dependency information in an explicit way. The dependency information is then used to support SLA management in three ways. First of all dependency information is used during SLA negotiation the to ensure that the different SLAs enable the successful collaboration of the services to achieve the composite service goal. Secondly, during SLA renegotiation dependency information is used to determine which effects the renegotiation has on other SLAs. Finally, dependency information is used during SLA monitoring to determine the effects of detected violations on other services.
Based on a literature study and two use cases from the logistics and healthcare domains different types of dependencies were analyzed and classified. The results from this analysis were used as a basis for the development of an approach to analyze and represent dependency information according to the different dependency properties. Furthermore, a lifecycle and architecture for managing dependency information was developed. In an iterative approach the different artifacts were implemented, tested based on two use cases, and refined according to the test results Finally, the prototype was evaluated with regard to detailed test cases and performance measurements were executed.
The resulting dependency management approach has four main contributions. Firstly, it represents a holistic approach for managing service dependencies with regard to composite SLA management. It extends existing work by supporting the handling of dependencies between atomic services as well as atomic and composite services at design time and during service provisioning. Secondly, a semi-automatic approach to capturing dependency information is provided. It helps to achieve a higher degree of automation as compared to other approaches. Thirdly, a metamodel for representing dependency information for SLA management is shown. Dependency information is kept separately from SLA information to achieve a better separation of concerns. This facilitates the utilization of the dependency management functionality with different SLA management approaches. Fourthly, a dependency management architecture is presented. The design of the architecture ensures that the components can be integrated with different SLA management approaches. The test case based evaluation of the dependency management approach showed its feasibility and correct functioning in two different application domains. Furthermore, the performance evaluation showed that the automated dependency management tasks are executed within the range of milliseconds for both use cases.
The dependency management approach is suited to support the different SLA management tasks. It supports the work of composite service providers by facilitating the SLA management of complex service compositions.

Double Threat - Trauma and PTSD in Adolescents with Substance Use DisordersBasedow, Lukas Andreas 05 October 2022 (has links)
Background: Substance use disorders (SUDs) are a great burden on adolescent patients and treatment of these patients is often not successful. One reason for this difficulty is the high rate of co-occurring disorders. One disorder that frequently accompanies SUDs in adolescence is a Post-Traumatic Stress Disorder (PTSD). In studies it has often been reported that a large number of patients fulfill diagnostic criteria for both disorders at the same time. Several explanations for this co-occurrence exist: i) A common etiological factor (genetic predisposition, similar neurobiological pathways) might underlie the development of both disorders. ii) Various lifestyle factors that go hand-in-hand with an adolescent SUD (risky sexual behavior, violent dark markets) might expose patients to circumstances that increase the rate of encountered traumatic experiences (TEs) and therefore PTSD. iii) The self-medication hypothesis, where it is posited that adolescents use drugs to medicate their PTSD symptoms, often in a very specific manner, such that particular substances are used to reduce explicit symptoms. One aim explored in this thesis is the relationship between SUD, TEs, and PTSD with regard to differences in SUD severity, patterns of substance use, the role of self-medication and the effects of SUD-specific treatment on PTSD symptomatology. Methods: Five studies are presented in chapters 2 to 6 of this thesis. Chapter 2 contains a study in which the Drug Use Disorder Identification Test (DUDIT) was evaluated for use in a psychiatric adolescent patient population. This was the first study in which the DUDIT in relation to DSM-5 criteria was evaluated, in order to try to establish cut-off scores for the presence of a SUD in adolescents. In chapter 3 an evaluation is presented of the differences in SUD severity between adolescents with a SUD (‘noTE’ group), adolescents with a SUD and a history of TE but not PTSD (‘TE’ group) and adolescents with SUD and co-occurring PTSD (‘PTSD’ group). In the study presented in chapter 4 an investigation of the differences in substance use patterns between the three groups was undertaken, along with an evaluation of the associations between PTSD symptoms and use of specific substances. In chapter 5, the role coping motives play in the relationship between substance and PTSD symptoms was established. Finally, in chapter 6 the results of a pragmatic clinical trial are presented, in which the effects of a group-based treatment manual (the DELTA program) on SUD symptoms, substance use frequency and PTSD symptoms are assessed. Results: Across all included studies in this dissertation, an instrument for the assessment of SUD in adolescents was evaluated. This was used with other instruments, to establish a link between adolescent SUD and increased rates of PTSD and substance use. Furthermore, the connection between SUD and PTSD in adolescence seems to be related to a self-medication motive. Additionally we established a treatment program that reduced SUD symptoms but failed to influence the PTSD symptoms, which indicates treatment specific to one disorder is unlikely to support reductions in the co-occurring disorder. More specifically, the results presented in chapter 2 showed that the DUDIT has excellent discriminant validity and is a valid tool for the assessment of SUD severity in a clinical adolescent population. In chapter 3, it was shown that the prevalence of TEs and PTSD in adolescents with SUD is higher than in the general adolescent population. Furthermore, the PTSD group showed a significantly higher level of SUD severity than the other two groups. In contrast to our expectations, the TE group did not differ significantly with regard to SUD severity from the noTE group. In addition, SUD severity correlated positively with the number of PTSD symptoms in each symptom cluster. The study presented in chapter 4 showed that past-month substance use frequency was nearly the same across groups and across substances, with only the use of methylenedioxymethamphetamine (MDMA) being significantly more frequent and more prominent in the PTSD group compared to the other two. Participants in the PTSD group also reported a significantly earlier age of first substance use compared to participants in the other two groups. Moreover, in this study it was shown that the presence of the avoidance symptom cluster of PTSD was related to a more frequent past-month MDMA use. The findings presented in chapter 5, confirmed the pattern detected for past-month substance use in chapter 4. The PTSD group showed a more frequent MDMA use over the past-year compared to the other two groups. Additionally, the PTSD group reported using substances more frequently for coping reasons, and the frequency of coping use motives was positively correlated with the frequency of past-year MDMA use. In this study, evidence was provided that the relationship between group membership (noTE, TE, PTSD) and MDMA use frequency is in part mediated by the relationship both variables have with coping use motives. In chapter 6 medium-sized but non-significant reductions were shown in SUD symptoms and substance use frequency as a result of the DELTA intervention. Additionally, there was no indication that the treatment program resulted in changes in PTSD symptomatology. Discussion: Several important conclusion can be derived from the studies presented in this thesis. First, a co-occurring PTSD is more prevalent in SUD patients than in the general adolescent population and is associated with higher SUD severity. Second, patients with co-occurring PTSD and SUD are distinguished from SUD patients without PTSD through their increased use of MDMA. Third, the relationship between PTSD and MDMA use is partially mediated by a coping motive, supporting the self-medication hypothesis. Finally, the treatment of co-occurring PTSD and SUD seems to require therapeutic interventions specific for each disorder. The result that PTSD symptoms are not reduced after SUD-specific treatment can be interpreted as support for the self-medication hypothesis as well, in the sense that the treatment of the consequence (SUD) does not affect the preceding factor (PTSD). However, while the above interpretation is consistent with the data presented in this thesis on substance use itself, the associated data on the occurrence of SUDs indicates, that more factors than just self-medication are relevant for the development of a SUD. Furthermore, the results of this thesis do not imply that substance use motivated by self-medication motives is harmless or even beneficial, since there was no way of assessing if self-reported, coping-motivated substance use is successful in reducing symptoms or acute psychopathology. Consequently, in future projects focus should be on developing longitudinal research designs, in order to assess if and how PTSD symptoms develop over time with regard to substance use and how substance use trajectories develop in relation to PTSD symptomatology.

Description Logics with Concrete Domains and Functional DependenciesLutz, Carsten, Miličić, Maja 31 May 2022 (has links)
Description Logics (DLs) with concrete domains are a useful tool in many applications. To further enhance the expressive power of such DLs, it has been proposed to add database-style key constraints. Up to now, however, only uniqueness constraints have been considered in this context, thus neglecting the second fundamental family of key constraints: functional dependencies. In this paper, we consider the basic DL with concrete domains ALC(D), extend it with functional dependencies, and analyze the impact of this extension on the decidability and complexity of reasoning. Though intuitively the expressivity of functional dependencies seems weaker than that of uniqueness constraints, we are able to show that the former have a similarly severe impact on the computational properties: reasoning is undecidable in the general case, and NExpTime-complete in some slightly restricted variants of our logic.

Prevalence of Use, Abuse and Dependence of Illicit Drugs among Adolescents and Young Adults in a Community SamplePerkonigg, Axel, Lieb, Roselind, Wittchen, Hans-Ulrich 03 December 2012 (has links) (PDF)
Prevalence findings for 1995 of illicit drug use as well as DSM-IV abuse and dependence are reported from a representative population sample of 3,021 respondents from Munich, Germany, aged 14–24 years. Results are based on personal interviews using the M-Composite International Diagnostic Interview (M-CIDI) with its DSM-IV diagnostic algorithms. Findings indicate that more than 30% of the adolescents and young adults are or have been using one or more illicit drugs at least once in their life. Men were slightly more likely to ever use drugs and used them more frequently than women. Cannabinoids were by far the most frequently used type of drug, followed by various stimulating drugs and hallucinogens. There is also considerable polysubstance use among 14- to 24-year-olds. Criteria for DSM-IV abuse without dependence were met by 4.1% of all men and 1.8% of all women, a dependence syndrome of any type of illicit drug was diagnosed in 2.5% of the men and 1.6% of the women. Cumulative age of onset incidence analyses suggest that substance use starts early, in about one-third before the age of 16 years and continues to rise for most drugs throughout adolescence and young adulthood. Overall these findings suggest that substance use and substance disorders are more prevalent than suggested in most previous German studies.

The natural course of cannabis use, abuse and dependence over four years: a longitudinal community study of adolescents and young adultsSydow, Kirsten von, Lieb, Roselind, Höfler, Michael, Sonntag, Holger, Wittchen, Hans-Ulrich 05 April 2013 (has links) (PDF)
Objectives: To determine incidence and patterns of natural course of cannabis use and disorders as well as cohort effects in a community sample of adolescents and young adults.
Method: Cumulative incidence and patterns of cannabis use and disorders were examined in a prospective longitudinal design (mean follow-up period=42 months) in a representative sample (N=2446) aged 14–24 years at the outset of the study. Patterns of cannabis use, abuse and dependence (DSM-IV) were assessed with the Composite International Diagnostic Interview (M-CIDI).
Results: (1) Cumulative lifetime incidence for cannabis use (at second follow-up): 47%; 5.5% for cannabis abuse, 2.2% for dependence. (2) Men used and abused cannabis more often than women. (3) The majority of the older participants (18–24 years at baseline) had reduced their cannabis use at follow-up, while younger participants (14–17 years at baseline) more often had increased their use and developed abuse or dependence. (4) The younger birth cohort (1977–1981) tended to start earlier with substance (ab)use compared to the older birth cohort (1970–1977). (5) Cannabis use was associated with increasing rates of concomitant use of other licit and illicit drugs.
Conclusions: Cannabis use is widespread in our sample, but the probability of developing cannabis abuse or dependence is relatively low (8%). The natural course of cannabis use is quite variable: about half of all cannabis users stopped their use spontaneously in their twenties, others report occasional or more frequent use of cannabis.

Wie stabil sind Drogenkonsum und das Auftreten klinisch-diagnostisch relevanter Mißbrauchs- und Abhängigkeitsstadien bei Jugendlichen? / Stability of cannabis use, abuse and dependence patterns in a community sample of adolescentsWittchen, Hans-Ulrich, Höfler, Michael, Perkonigg, Axel, Sonntag, Holger, Lieb, Roselind 23 October 2012 (has links) (PDF)
Anhand einer prospektiven epidemiologischen Verlaufsstudie an einer repräsentativen Bevölkerungsstichprobe von ursprünglich 14- bis 17jährigen Jugendlichen (N=1395) werden die Häufigkeit und die Verlaufsmuster des Konsums, des Mißbrauchs und der Abhängigkeit von Cannabis untersucht. Die Jugendlichen wurden persönlich mit Hilfe eines Interviews befragt, wobei als diagnostisches Instrument das M-CIDI mit seinen DSM-IV Algorithmen verwendet wurde. Die Ergebnisse aus der Basiserhebung ergaben, daß 1995 etwa 20% aller 14- bis 17jährigen - in der Mehrzahl wiederholt - Cannabis probiert hatten und 6% der Population einen regelmäßigen Gebrauch aufweisen. Die Einjahres-Inzidenz (= Auftreten neuer Fälle) für den Cannabisgebrauch der nun 15- bis 19jährigen betrug zum Zeitpunkt der Nachuntersuchung 20,1% für die Männer und 16,3% für die Frauen. Für den regelmäßigen Gebrauch wurden Inzidenzraen von 12% (Männer) und 8,4% (Frauen) ermittelt. Die Stabilität des Konsumverhaltens zwischen der Basis- und der Nachuntersuchung war relativ hoch un stieg mit höherem Initialkonsum an. Angesichts der hohen Gebrauchsrate von 32,4% bei den 15- bis 19jährigen bei der Nachuntersuchung ergab sich im Vergleich zu anderen psychotropen Substanzen eine relativ niedrige Prävalenz für Mißbrauch und Abhängigkeit (4%). Das Vorliegen einer Diagnose bei der Erstuntersuchung weist allerdings eine relativ hohe Stabilität über die Nachuntersuchungskette auf. / The paper examines the prevalence, incidence and stability patterns of cannabis use and dependence in a prospective epidemiological study of a random community sample of adolescents, aged 14 to 17 years (N=1395) at time 1. Assesments are based on personal interviews by trained clinical psychologists using the computerized DSM-IV lifetime and 12-month change version of the M-CIDI. Results indicate that in 1995 every fifth person aged 14 to 17 years had used cannabis at least once and 6% reported regular use. The 12-month incidence rates (i.e. proportion of the sample reporting first cannabis use in the last year) among subjects, 15 to 19 years of age at time 2, was high, with 20,1% of males and 16,3% of females reporting first use. The incidence of regular use was 12,0% (males) and 8,4% (females). The stability of consumption patterns from time 1 to time 2 was high. Increasing with higher initial consumption. Given the reexamined samples overall high cannabis consumption rates of 32,4%, the prevalence of clinically manifest DSM-IV abuse and dependence was low in comparison to other psychologic drugs (4%). However there was remarkable diagnostic stability over time in this age group of those with an initial diagnosis at time 1 receiving a diagnosis again at time 2.

Feasibility and outcome of substitution treatment of heroin-dependent patients in specialized substitution centers and primary care facilities in Germany: A naturalistic study in 2694 patientsWittchen, Hans-Ulrich, Apelt, Sabine M., Soyka, Michael, Gastpar, Markus, Backmund, Markus, Gölz, Jörg, Kraus, Michael R., Tretter, Felix, Schäfer, Martin, Siegert, Jens, Scherbaum, Norbert, Rehm, Jürgen, Bühringer, Gerhard 11 April 2013 (has links) (PDF)
Background: In many countries, buprenorphine and methadone are licensed for the maintenance treatment (MT) of opioid dependence. Despite many short-term studies, little is known about the long-term (12-month) effects of these treatments in different settings, i.e. primary care-based (PMC) and specialized substitution centers (SSCs).
Objectives: To describe over a period of 12 months: (1) mortality, retention and abstinence rates; (2) changes in concomitant drug use, somatic and mental health; and (3) to explore differences between different types of provider settings.
Methods: 12-Month prospective-longitudinal naturalistic study with four waves of assessment in a prevalence sample of N= 2694 maintenance patients, recruited from a nationally representative sample of N= 223 substitution physicians.
Results: The 12-month retention rate was 75%; the mortality rate 1.1%. 4.1% of patients became “abstinent” during follow-up. 7% were referred to drug-free addiction treatment. Concomitant drug use decreased and somatic health status improved. No significant improvements were observed for mental health and quality of life. When controlling for initial severity, small PMC settings revealed better retention, abstinence and concomitant drug use rates.
Conclusion: The study underlines the overall 12-month effectiveness of various forms of agonist MT. Findings reveal relatively high retention rates, low mortality rates, and improvements in most 12-month outcome domains, except for mental health and quality of life. PMC settings appear to be a good additional option to improve access to MTs.

Advancing the discovery of unique column combinationsAbedjan, Ziawasch, Naumann, Felix January 2011 (has links)
Unique column combinations of a relational database table are sets of columns that contain only unique values. Discovering such combinations is a fundamental research problem and has many different data management and knowledge discovery applications. Existing discovery algorithms are either brute force or have a high memory load and can thus be applied only to small datasets or samples. In this paper, the wellknown GORDIAN algorithm and "Apriori-based" algorithms are compared and analyzed for further optimization. We greatly improve the Apriori algorithms through efficient candidate generation and statistics-based pruning methods. A hybrid solution HCAGORDIAN combines the advantages of GORDIAN and our new algorithm HCA, and it significantly outperforms all previous work in many situations. / Unique-Spaltenkombinationen sind Spaltenkombinationen einer Datenbanktabelle, die nur einzigartige Werte beinhalten. Das Finden von Unique-Spaltenkombinationen spielt sowohl eine wichtige Rolle im Bereich der Grundlagenforschung von Informationssystemen als auch in Anwendungsgebieten wie dem Datenmanagement und der Erkenntnisgewinnung aus Datenbeständen. Vorhandene Algorithmen, die dieses Problem angehen, sind entweder Brute-Force oder benötigen zu viel Hauptspeicher. Deshalb können diese Algorithmen nur auf kleine Datenmengen angewendet werden. In dieser Arbeit werden der bekannte GORDIAN-Algorithmus und Apriori-basierte Algorithmen zum Zwecke weiterer Optimierung analysiert. Wir verbessern die Apriori Algorithmen durch eine effiziente Kandidatengenerierung und Heuristikbasierten Kandidatenfilter. Eine Hybride Lösung, HCA-GORDIAN, kombiniert die Vorteile von GORDIAN und unserem neuen Algorithmus HCA, welche die bisherigen Algorithmen hinsichtlich der Effizienz in vielen Situationen übertrifft.

Substance Use and Substance Use Disorders in a Community Sample of Adolescents and Young Adults: Incidence, Age Effects and Patterns of UsePerkonigg, Axel, Pfister, Hildegard, Höfler, Michael, Fröhlich, Christine, Zimmermann, Petra, Lieb, Roselind, Wittchen, Hans-Ulrich 29 November 2012 (has links) (PDF)
Objective: We present the prevalence and incidence rates of alcohol, nicotine, and illicit substance use, abuse, and dependence in a sample of German adolescents and young adults. Patterns of onset, cohort trends, and use of various substance classes are also analyzed.
Method: A prospective longitudinal epidemiological study with a representative sample of adolescents and young adults (n = 3,021; baseline age range = 14–24 years) was conducted in Munich, Germany. Participants were assessed between 1995 and 1999 with the Munich-Composite International Diagnostic Interview.
Results: Cumulative lifetime incidence (up to age 28) of any substance abuse or dependence was 43.8%, and 12-month prevalence of any substance abuse or dependence was 24.4%. The lifetime incidence of nicotine dependence was most frequent (24.8%), followed by alcohol abuse (19.3%) and alcohol dependence (9.2%); 61.7% endorsed the regular use of a substance for at least one circumscribed period during their lifetime. Age-specific incidence rates and age at onset of substance use disorders differed by age cohorts. Furthermore, nicotine dependence was significantly associated with illicit substance use disorders (HR = 2.6, 95% CI 1.7–4.0). An interactive relationship between age, age at onset of nicotine dependence, and subsequent onset of illicit substance use disorders was found.
Conclusions: Since the baseline investigation in 1995, high incidence rates of substance use disorders and substance use have been observed in this young German sample. Especially younger cohorts report significantly earlier ages at onset of abuse and dependence. There also seems to be a trend towards a secondary age at onset peak of nicotine dependence after the onset of illicit drug use disorders. Further investigations are needed to study these patterns in younger samples. However, results emphasize the need for a combined prevention of illicit drugs and nicotine dependence. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
