The relevance of this work consists that possibilities of financial management are still insufficiently studied by working capital of the enterprise and sources of his formation for management of the large industrial companies. In this regard in work are investigated theoretical and methodological bases of management of working capital, the structure of working capital of the PJSC Electrozinc enterprise is analyzed and on this basis problems of management of working capital at the enterprise come to light and concrete ways of their solution are proposed. / Актуальность данной работы состоит в том, что возможности финансового управления оборотным капиталом предприятия и источниками его формирования еще недостаточно изучены для целей управления крупными промышленными компаниями. В связи с этим в работе исследуются теоретическую и методологическую основы управления оборотным капиталом, анализируется структура оборотного капитала предприятия ПАО «Электроцинк» и на этой основе выявляются проблемы управления оборотным капиталом на предприятии и предлагаются конкретные пути их решения.

Актуальность данной работы состоит в том, что задача оптимизации структуры капитала одновременно представляет собой ключевую и одну из самых сложных задач, решаемых в области корпоративных финансов. В итоге, целью организации заключается в одновременной минимизации фактической стоимости привлеченных средств и минимизации рисков банкротства. В работе исследуются теоретические основы определения оптимальной структуры денежного капитала предприятия, анализируется структура денежного капитала предприятия ПАО ГМК «Норильский никель», а также рассматриваются современные проблемы оптимизации структуры денежного капитала на предприятии и предлагаются конкретные пути их решения. / The relevance of this work is that the task of optimizing the capital structure is simultaneously a key and one of the most difficult tasks to be accomplished in the field of corporate finance. As a result, the purpose of the organization is to simultaneously minimize the actual cost of borrowed funds and minimize the risks of bankruptcy. The paper studies the theoretical foundations for determining the optimal structure of the company's cash capital, analyzes the structure of the company's cash capital, the public company Norilsk Nickel Mining and Metallurgical Company, and examines modern problems of optimizing the structure of money capital in the enterprise and suggests specific ways to solve them.

För individer med parodontal sjukdom är egenvården betydelsefull för en bättre prognos. Förebyggande åtgärder kan behöva ses i ett större sammanhang om det ska vara möjligt att främja tandhälsa eller förhindra fortsatt tandsjukdom. En insikt i patientens upplevelser och syn på sin förbättrade egenvård kan vara värdefull för att bättre förstå vad som behöver hända för att det ska ske en förflyttning mot en bättre hälsa. Syftet var att beskriva innebörden av ett upplevt förbättrat munhälso¬relaterat beteende sett utifrån ett patientperspektiv. Studiepopulation & metod: Deskriptiv fenomenologisk metod (Giorgi) valdes för insamling och analys av data. Det gjordes ett urval från patienter på en privat praktik för allmäntandvård.Resultatet visade fenomenets generella struktur med dess åtta inbördes bestånds-delar som i korthet är: a) förändring som en successiv ökning, b) förändrad syn på egenvård, c) detaljerad förståelse, automatisk rutin, och förbättring, d) uppmaningar och feedback upplevs förstärkande, e) goda tankar och tillfredställande känsla över sin egen förmåga, f) medverkan och tilltro till expert samt stimulans och upprätthållande, g) negativa erfarenheter och begränsningar, h) relatera sig själv till dåtid, nutid, framtid och andra.Diskussion: Ett salutogent patientcentrerat perspektiv framträdde. Det visade ett komplext samspel mellan förstärkande inre och yttre faktorer som slutligen resulterade i ett förbättrat munhälsorelaterat välbefinnande samt en egenvårdsrutin som upplevs som väl integrerad i vardagen. Resultatet tyder på att en förbättrad egenvård ger en ökad munhälsorealterad livskvalitet som kan behöva undersökas närmre. / For individuals with parodontal disease self-care is important for the prognosis. To be able to prevent progression of oral diseases health promotion and preventive interventions should be seen in a larger context. An insight in the patient´s experiences of her improved self-care could be valuable for a better understanding of what it´s like to move towards the direction of a better health.The aim was to describe the meaning of a perceived improved oral health related behavior from the patients´ perspective.Study population & method: Descriptive phenomenological method (Giorgi) was chosen for collection and analysis of data. A selection from patients in a private dental practice was made.The result showed the general structure and its eight constituents: a) change as a successive increase, b) a changed view on self-care, c) a detailed understanding, an automatic routine, and improvement, d) motivating challenges and feedback are perceived as strengthening, e) good thoughts and a satisfying feeling over own capacity, f) complicity and credence to an expert, and stimulation and maintenance, g) negative experiences and limitations, h) relating yourself to past time, present time, future and other people.Discussion: A salutogenic patient-centered perspective appeared. It showed a complex interaction between strengthening internal and external factors which finally resulted in improved oral health related wellbeing and a self-care routine which was experienced as well integrated in the everyday life. The result indicates that improved self-care results in increased oral health related quality of life which needs further investigation.

L’atteinte d’un soulagement adéquat de la douleur garantissant aussi une utilisation sécuritaire des opioïdes et répondant aux attentes des patients s’est beaucoup complexifiée dans le contexte d’une attention accrue à l’utilisation et aux effets néfastes des opioïdes. Cette attention a remis en question les pratiques de prescription et distribution de médicaments visant le soulagement de la douleur. En tant que dispensateurs de médicaments, les pharmaciens assument un rôle central pour en assurer leur utilisation sécuritaire et appropriée. L’objectif général de ce travail est de décrire les pratiques pharmaceutiques portant sur le soulagement de la douleur dans le contexte actuel en Amérique du Nord en général et au Québec en particulier, et mieux comprendre les facteurs facilitants et les barrières à l’amélioration de ces pratiques au Québec. Ce projet a été mené en deux parties. Tout d’abord, une revue de la littérature a été effectuée pour recenser les publications examinant les pratiques pharmaceutiques visant le soulagement de la douleur et la gestion des opioïdes en lien avec une préoccupation généralisée sur l’usage des opioïdes. Les objectifs étaient d'identifier ces pratiques et d'évaluer si elles avaient été amenées à évoluer suite à ces préoccupations. Pour la deuxième partie du projet, qui visait à approfondir les perceptions des pratiques pharmaceutiques portant sur la douleur au Québec, des entrevues semi-structurées ont été menées avec des pharmaciens (n = 8) oeuvrant dans divers milieux cliniques (pharmacie communautaire, pharmacie en établissement de santé et groupe de médecine de famille). Alors que les pharmaciens ont exprimé le désir de jouer un rôle central dans l'atteinte des objectifs de traitement de la douleur tout en assurant l’utilisation sécuritaire des opioïdes, ils ont rapporté plusieurs obstacles dans leur pratique. De plus, la prestation des soins pharmaceutiques visant le soulagement de la douleur pourrait être améliorée en tirant parti des facilitateurs de chaque milieu de pratique et en favorisant les partenariats intraprofessionnels à travers les différents milieux de pratique. / Providing adequate pain relief while ensuring safe opioid use and managing patient expectations has become an intricate endeavor in the context of increased attention to opioid use and its harms. This attention has put into question the practices of prescribing and dispensing medications for pain relief. As the dispensers of medications, pharmacists play a crucial role in ensuring their safe and proper use. The general objective of this work is to describe the pharmaceutical practices encompassing pain relief in the current context in North America in general, and in Quebec in particular, and to better understand the facilitating factors and the barriers to the improvement of these practices in Quebec.This project was conducted in two parts. First, a scoping review of the literature was conducted for publications examining pharmaceutical practices aimed towards pain relief and opioid management in the context of widespread concern about opioid use. The objectives were to identify these practices and assess whether they had been called on to evolve as a result of these concerns. For the second part of the project, which aimed to deepen the perceptions of pharmaceutical practices relating to pain in Quebec, semi-structured interviews were conducted with pharmacists (n = 8) working in various clinical settings (community pharmacy, health facility pharmacy and family medicine group). While pharmacists have expressed a desire to play a central role in achieving pain treatment goals while ensuring the safe use of opioids, they reported several barriers in their practice. Lack of time to perform adequate follow-ups, gaps in pain assessment and pharmacotherapy knowledge, and communication skills tailored to patients who suffer were the main barriers mentioned by pharmacists. Adjustments to teaching and practice curricula, standardized assessment and monitoring tools, and increased patient involvement in decision-making could prove beneficial. In addition, delivery of pharmaceutical care for pain relief could be improved by leveraging facilitators from each practice setting and fostering intraprofessional partnerships across different practice settings.

The object-oriented paradigm is widely advocated and has been used in South African universities since the late 1990s. Object-oriented computer programming is based on the object-oriented paradigm where objects are the building blocks that combine data and methods in the same entity. Students' performance in object-oriented programming (OOP) is a matter of concern. In many cases they lack the ability to apply various supportive techniques in the process of programming. Efficient knowledge, skills and strategies are required during problem solving to enhance the programming process. It is often assumed that students implicitly and independently master these high-level knowledge, skills and strategies, and that teaching should focus on programming content and coding structures only. However, to be successful in the complex domain of OOP, explicit learning of both programming and supportive cognitive techniques is required. The objective of this study was to identify cognitive, metacognitive and problem-solving knowledge, skills and strategies used by successful and unsuccessful programmers in OOP. These activities were identified and evaluated in an empirical research study. A mixed research design was used, where both qualitative and quantitative methods were applied to analyse participants' data. As a qualitative research practice, grounded theory was applied to guide the systematic collection of data and to generate theory. The findings suggest that successful programmers applied significantly more cognitive-, metacognitive- and problem-solving knowledge, skills and strategies, also using a greater variety, than the unsuccessful programmers. Since programming is complex, we propose a learning repertoire based on the approaches of successful programmers, to serve as an integrated framework to support novices in learning OOP. Various techniques should be used during problem solving and programming to meaningfully construct, explicitly reflect on, and critically select appropriate knowledge, skills and strategies so as to better understand, design, code and test programs. Some examples of teaching practices are also outlined as application of the findings of the study. / Mathematical Sciences / PhD. (Nathematics, Science and Tecnical Education)

我國近年來有關家庭的研究，均著重在女性就業、單親家庭、兒童、青少年、老人、受暴婦女議題。對於家庭主要生計負責人的男性角色，只有莫黎黎、王行等研究。軍人是特殊的群體，我國約有10萬名的志願役軍官，9成以上均為男性，但未受到重視，相關文獻與研究亦少。本研究是以我國軍官為研究樣本，他們平均每天的工作時間超過12小時，平均一週也只有1.96天，可以回家和家人相聚，其生活方式與一般百姓略有不同。 一位志願役軍官，職責是保國衛民，因此常留守部隊，或因任務需求而不斷調遷，國軍「精實案」期間，使得軍人責任加重、工作時間長、工作壓力大，這些都影響他們與家庭的互動關係。軍人會不會因為其特殊的角色、特殊工作時間、特殊工作型態，忽略了家庭的照顧呢？會因此產生角色衝突嗎？軍人與家人的互動關係如何？自己的生活滿意呢？這是本研究的動機。 本研究同時運用量化研究法與質化研究法，首先以量化研究，設計了「角色衝突」與「生活滿意」的封閉性問卷，施測了1390位軍官。再設計了「家庭狀況」、「工作狀況」及「角色衝突」的開放式問卷，深度訪談8位軍官。最後，邀請3組軍官，做焦點團體訪談，針對前述研究結果／進行深度討論。 本研究的自變項有人口變項及軍人特質變項，「角色衝突」則分為：因工作而疏忽與家人相處的衝突、因工作而干擾夫妻關係的衝突、家庭角色內的衝突、因家庭責任而犧牲自己的衝突、因工作而疏忽子女教養的衝突、工作角色家庭角色與自我角色的衝突、因家庭責任妨礙追求工作成就的衝突。「生活滿意」包括：家庭生活滿意、婚姻滿意、人際關係滿意、一般生活滿意、父母與配偶互動關係的滿意、休閒生活滿意等。 本研究在量化部份，共收集已婚軍官974人，平均結婚年齡為6.07年。研究發現，整體而言，軍官的角色衝突依序為：家庭角色內的衝突、因家庭責任而犧牲自己的衝突、工作角色家庭角色與自我角色的衝突」、因工作而疏忽與家人相處的衝突、困工作而疏忽子女教養的衝突、因工作而干擾夫妻關係的衝突、因家庭責任妨礙追求工作成就的衝突。而且一半的軍官有角色衝突的情形，沒有角色衝突的軍官較少，但亦有三分之一的軍官是介於二者之間，可知，軍官的角色衝突情形是值得重視的。 軍官的生活滿意依序為家庭生活、婚姻、家庭人際關係、父母與配偶互動關係、休閒生活、一般生活。也發現有三分之二的軍官是滿意自己的生活情形，不滿意自己生活的軍官很少，但有27%的軍官是介於二者之間。 影響角色衝突的變項當中，發現男性、配偶不是軍人、協助做家事、陸軍、上尉、基層單位、外島、配偶全職工作、回家頻率較少、生活最大滿足是父母、配偶、子女、以家庭為重、工作時間愈長、年餘愈輕、收入愈少、第一位子女出生年齡愈小、愈擔心退役以後工作與生活、精實案對工作與生活的影響愈大、長官愈不關心軍官工作與生活情形，其角色衝突較大。 影響生活滿意的變項當中，發現男性、非作戰單位、協助做家事、研究所、戰院教育、上校、其他軍種、軍團以上、結婚15年以上、配偶全職工作、房屋是自己購買、與父母配偶同住、生活最大滿足是父母、配偶、子女、以家庭為重、工作時間愈短、年齡愈大、收入愈高、愈不擔心退役以後工作與生活、精實案對工作與生活的影響愈小、長官愈關心軍官工作與生活情形，其生活滿意較高。而且角色衝突愈少者，其生活滿意度也愈高。 本研究在進行量化研究後，接著進行「深度訪談」，軍官雖然會運用一些方法，來減少角色衝突，但仍不免有衝突的產生，包括夫妻間的衝突、配偶與家人的衝突、軍官與家人的衝突等，也會尋求避免衝突和解決衝突的方式： 一、軍官和配偶衝突的解決方式：面對面的溝通；用比喻的方式，期待配偶將心比心；主動向配偶對不起；讓配偶盡情發洩情緒；選擇某些事才讓配偶知道；接受配偶的意見；面對婚後爭吵的事實，事先協調好，以避免衝突的發生。 二、配偶和家人衝突的解決方式：了解婆媳問題是必然會存在的；接受婆媳觀念不一致的現況；婚前先協調好，預防婆媳問題的發生；在媽媽與配偶之間，做一些取捨；在假日，盡量離開家裡，或者回娘家；減少配偶與婆婆接觸的機會，讓彼此的接觸有限，比較不會引發較大的衝突；軍官居於原生家庭、生殖家庭之間，二邊溝通協調；藉由退伍，調整生活方式，以改變現況；選擇不同時間，分別關心原生家庭和生殖家庭，避兔讓原生家庭和生殖家庭產生衝突。 本研究最後以三坎的「焦點團體」訪談法，針對量化研究獲得的資料，再進一步訪談軍官。發現軍官覺得家庭角色和工作角色的衝突滿大的，因為在工作上衝刺的話，可以得到很多工作滿意，但若沒有配偶或家庭的支持，則生活也不滿意。衝突處理的方式有：將工作與家庭儘量分開；把工作做完，再照顧家庭，回家後，多關心家人，或在休假日協助做家事，以體諒家人；覺得虧欠家人，會有補償家人的心態；會先處理家庭的事務，再處理工作事務；期望長官應同時關心部屬的生活和工作；利用家庭其他親戚的力量，協助照顧自己的家庭；加強夫妻、子女之間的溝通，以維繫感情；重視互相體諒，主動協助做家事；有些配偶會讓軍官盡量在工作上衝刺、盡力去發揮。綜合而言，軍官對生活滿意的看法，認為軍人是很好的職業，收入穩定。 最後，透過本研究的發現，提出以下建議： 一、對軍事組織的建議 (一) 減少工作時間或降低軍官的工作負荷 (二) 建立職務代理制度 (三) 建立眷屬來部隊省親的機制，並建設眷屬省親的臨時住所 (四) 增設職務官舍，解決軍官的居住問題，增進親情關係 (五) 長官應多傾聽部屬的意見，並關懷部屬的工作狀況與家庭生活 (六) 應重視軍官的生涯規畫 (七) 建議未來「精進案」應提早有整體的配套措施 二、對軍官的建議 (一) 認識自己面臨的角色衝突與生活滿意狀況 (二) 學習認知自己的角色與職責 (三) 建議婚姻不和諧的軍官應勇於向專業人員尋求協助 (四) 建議家庭不和諧的軍官應勇於向專業人員尋求協助 (五) 鼓勵軍官在適當時機，提出適當的建議，以促進部隊進步 三、對軍眷管理單位的建議 (一) 規畫軍人家庭政策 (二) 建立軍人家庭福利服務 (三) 上維護與發揮家庭功能 (四) 成立軍眷互助中心 (五) 加強托兒、托老服務 (六) 加強配偶的職業輔導 四、在現有組織中增進專業軍隊社會工作 (一) 強化「心理衛生中心」的服務功能 (二) 增設社會工作軍官 (三) 運用專業社會工作方法，預防角色衝突 (四) 建立軍事社區與民間社區之關係 五、對一般家庭協助機構的建議 (一) 建立良好的家庭支持系統 (二) 重視家庭和諧，加強家庭成員的情感連結 (三) 增加有關家庭關係相關課程，舉辦親職教育，增加親子互動 (四) 加強婚姻與家人關係的協助 (五) 營造兩性平權，促進家庭生活現代化 (六) 開設衝突管理的課程 軍人將人生最精彩的青壯年貢獻給國家，也將自己全副精力服務部隊，而家庭與配偶仍是軍官生活滿意的主要來源，尤其來自於配偶的支持是最大的，配偶無私的支持，竭盡心力，奉獻家庭，讓軍官能不斷往前衝刺，追求事業的成功。所以配偶扮演一種穩定的角色，讓我國軍官較無後顧之憂，因此軍人內心裡，對配偶都存在有愧疚感。自己的父母親、配偶的父母親，也是軍官的最佳資源，讓軍官可以無後顧之憂的投入工作。 關鍵字：志願役軍官、角色期待、角色衝突、生活滿意、量化研究法、質性研究法 / The recent relating family research in our country are mostly concentrated on the issue of women's occupation, single-parent family, the children, the youth, the aged, and female abuse. The research toward the male who actually support the family's income are found rarely from the article of "Mo Li Li"（莫藜藜） and "Wang Xing" （王行）. The soldiers is a distinguishing group, there are around hundred thousand of the volunteer officers in this country and more than 90% of them are male, they are an ignored group and not many articles and researches in this field have been really dedicated for them. The quantitative methods and qualitative methods were applied by this research. The close questionnaire of "role conflict" and "life satisfaction" that tested to 1,390 officers initiated the quantitative methods. The open questionnaire of "family status", "work status", and "role conflict" that proceeded by the depth interview to 8 officers was followed next. The focus group interview (session) to 3 groups of officers were the last that carried by the depth discussion toward the results of two previous methods. The officer's life satisfaction ranked by family life, marriage, family's human relationship, parent and spouse interaction, life resort, and normal life. It is found that two thirds of the officers are satisfied with their living life, only a few are dissatisfied, and 27% of them are in the between. The variables that affecting the role conflict mostly are with the characters of the male; the spouse is not the soldier; willing to share the house works; the army; the captain; the fundamental unit service; the out island service; the spouse works full time; not often back home; the parents, spouse, and children are the most satisfaction of life; the family care; long working time; younger; less income; the first kit born too late; concerning about the work and life after the retiring; facing the supervisor's carelessness toward the job and life that are affected greatly from "the troop reduction plan". The officers with these kinds of variables have the more serious role conflict. The variables that affecting the life satisfaction mostly are with the characters of the male; the not combating unit service; willing to share the house works; the master degree; the war academy educated; the colonel; not from the army; the regiment unit service at least; the marriage of 15 years; the spouse works full time; owns the housing; living with parents and spouse; the parents, spouse, and children are the most satisfaction of life; the family care; short working time; older; higher income; not concerning about the work and life after the retiring; receiving the supervisor's care toward the job and life that are not affected actually from "the troop reduction plan". The officers with these kinds of variables have the less role conflict and more life satisfaction. The depth interviews were proceeded after the quantitative methods in this research. The officers would manage to reduce their role conflict, but the conflict remains and still existed in the spouse, the spouse and family, and the officer and family. The ways they normally sought to avoid or solve the conflict are such as a face to face communication; a initiative apology to the spouse; to accept the spouse's complete oppression relief; to accept the spouse's point of view; an advanced agreement to avoid the conflict after married; an understanding of the realistic problem that existed in between the mother and daughter in law; to accept the facts of discordance that existed in between the mother and daughter in law. The three times of the "focus group" interviews were the last of this research, the further interviews to these officers were aimed at the data that achieved from the previous quantitative methods. In general, the officers all agreed that the solider is a good career with stable revenue, it is their recognitions to the life satisfaction. Based on the results of this research, we are having our suggestions as follows: 1. to the military organization (1) reduce the officer's working time or to improve their overload problem. (2) set up the job substitution system. (3) set up the capacity of family visit and the temporary residence to accept the visit. (4) expand the official dormitory to improve the officer's residential problem and family relationship. (5) the supervisor should listen more to the opinion from the staff and extend the highly concern toward their work and family life. (6) respect the officer's career planning (7) the project of "troop reduction plan" should be executed with the other cooperative methods to pursue the integrated achievement. 2. to the officers (1) recognize the role conflict facing and the status of life satisfaction. (2) learn to know the self-role and self-responsibility. (3) seek for the assistance from the professional for the unpleasant marriage. (4) seek for the assistance from the professional for the unpleasant family life. (5) it is encouraged to submit the right proposition in due time to accelerate the unit's development. 3. to the authority of the solider family administration (1) plan out the soldier's family policy. (2) set up the soldier's family service. (3) maintain and extend the function of family. (4) set up the dependant service center. (5) improve the welfare for the child and aged. (6) improve the spouse's vocational assistance. 4. enhancing the professional military social work in the present organizations (1) expand the service function of "the mental health center". (2) increase the social work officers. (3) prevent the role conflict by means of the professional social work. (4) set up the relationship between the military community and the civil community. 5. to the general organizations of the family service (1) set up a successful family supporting system. (2) respect the importance of a pleasant family by strengthen the emotional communications between the family. (3) expand the educational course of the family relationship, to promote the family education and improve the interaction of parents and children. (4) help the officers to manage the unpleasant marriage or family relationship. (5) create the equal rights of male and female to enhance the modernizing of family life. (6) set up the educational course of the conflict management. The soldiers dedicate the most significant golden age of their life to the country and devote themselves completely to the missions. The family and spouse are the main supporting resources of the officer's life satisfaction, and most of that are from the spouse, they make sacrifice to the family and act as a role of great stability. The officers are able to pursue the honor and success without too much cares and anxieties toward the family, the inner of soldiers all existing a deep regret to their spouse. The parents of their own and of the spouse are also the key factors of the supporting. By the completion of this research, we sincerely looking forward to the continual efforts from the government, to improve the welfare for the soldiers and the officers. keywords: professional officer、role expectation、role conflict、life satisfaction、quantitative methods、qualitative methods.

Substance abuse and suicidal behaviour are major challenges to public health. These phenomena are mainly studied by quantitative designs. This qualitative thesis aims at gaining a deeper understanding of substance abuse and suicidal behaviour, as experienced by young men in different types of treatment. By describing, exploring and interpreting lived experiences, in this thesis I try to give a more nuanced language of both substance abuse and suicidal behaviour, also in young migrating men. I also focus on the system of services related to the prevention and follow-up of life-threatening overdoses by describing and exploring how this phenomenon is experienced by individuals and professionals in Oslo. By researching the lived experiences of substance abuse and suicidal behaviour, combined with researching the phenomenon of life-threatening overdoses, a deeper insight is gained and this can be an important source to both prevention and health promotion for the group in question. The first three papers are based on descriptive, explorative and interpretative studies. How meaning is constructed is the core research question. In the fourth study I describe and explore life-threatening overdoses as a contemporary phenomenon in its context. The research questions are on a descriptive level. In the first three papers, the research object is the personal narratives from in-depth interviews, which are analysed using a phenomenological hermeneutic method. The case study is composed of data collected from different sources, and analysed by triangulation. The main finding in the first paper is that substance abuse and suicidal behaviour can be understood as goal-oriented, communicative and meaning-making activities about the individuals’ balance between death as an escape from pain and the hope of a life. In the second study, metaphorical expressions about a shifting sense of self is understood as balancing being an agent or a victim. In migrating young men these phenomena are interpreted as goal-oriented, communicative and meanig-making activities about existing in a maze that is perceived as closed. The findings of the case study show that different forms of life-threatening overdoses in Oslo are experienced in a state of existential and material stress. A wish of follow-up might not be expressed by the individual. Due to structural problems, such as lack of goals, professionals do not prevent such events in a planned way, nor do they cooperate between different levels. Professionals decide what is good quality in prevention and follow-up of life-threatening overdoses / Rusavhengighet og selvmordsadferd representerer store folkehelseproblemer. Disse fenomenene er hovedsakelig studert med kvantitative design. Målet med denne kvalitative avhandlingen er å få dypere kunnskap om rusavhengighet og selvmordsadferd slik fenomenene er opplevd av yngre menn i ulike typer behandling. Gjennom å beskrive, undersøke og tolke levde opplevelser forsøker avhandlingen å få fram en mer nyansert forståelse av, og språk om, både rusavhengighet og selvmordsadferd, også hos yngre menn med migrasjonserfaring. Avhandlingen fokuserer systemnivået gjennom å beskrive og undersøke hvordan livstruende overdoser oppleves og erfares som levde erfaringer og som yrkesutfordring i Oslo. Et omverdensperspektiv, kombinert med en dypere forståelse og et rikere språk kan være viktige bidrag til forebyggende og helsefremmende tiltak. Det første, andre og tredje arbeidet i avhandlingen er beskrivende, undersøkende og tolkende studier som fokuser yngre menns levde erfaringer med rusavhengighet og selvmordsadferd. Hvordan mening konstrueres er det sentrale forskningsspørsmålet. Det fjerde arbeidet, case studien, undersøker livstruende overdoser i en nå-tidig kontekst, og forskningsspørsmålene er beskrivende. I de første tre arbeidene er forskningsobjektet personlige narrativer samlet gjennom åpne dybdeintervjuer, og som er tolket ved bruk av en fenomenologisk hermeneutisk analyse. I case studien er data fra ulike kilder analysert ved hjelp av triangulering. Hovedfunnet i den første studien er at rusavhengighet og selvmordsadferd kan forstås som måltettede, kommunikative og meningsfulle handlinger om personens balanse mellom døden som befrielse fra smerte og håpet om et bedre liv. I den andre studien kommer metaforiske beskrivelser av en skiftende opplevelse av seg selv i prosessene knyttet til både rusavhengighet og selvmordsadferd tydelig fram. Dette kan forstås som å balansere en selvopplevelse mellom aktør og offer. I den tredje studien kan rusavhengighet og selvmordsadferd hos migrerte menn forstås som målrettede, kommunikative og meningsfulle handlinger om personens opplevelse av å eksistere i en stengt labyrint. Funnene i case studien tyder på at livstruende overdoser i Oslo erfares i eksistensielt stressfulle omstendigheter. Et personlig ønske om oppfølging gis ikke alltid eksplisitt. Strukturelle problemer medfører at profesjonelle arbeider med livstruende overdoser uten overordnete mål og uten samordnet planlegging. Profesjonelle bestemmer derfor selv hva som er god kvalitet når det gjelder forebygging og oppfølging av livstruende overdoser

Autonomes Fahren könnte Autonutzung und -besitz grundlegend verändern – mit erheblichen Auswirkungen darauf, wie mit dem Automobil umgegangen wird, wie Mobilität und Verkehr künftig organisiert und städtebauliche und Verkehrsinfrastrukturen gestaltet werden. Ziel der Arbeit ist es, zu einer frühzeitigen und umfassenden Auseinandersetzung mit der Technik aus empirisch-sozialwissenschaftlicher Sicht beizutragen, sowie wesentliche Einflussfaktoren und Dynamiken der Technikentwicklung zu identifizieren, um diese gestaltend begleiten zu können. Bei technologiebasierter Entwicklung ist eine Vorhersage von möglichen Entwicklungspfaden schwierig, und Akzeptanz gilt als Schlüsselfaktor für die erfolgreiche Produkteinführung. Sie vollzieht sich mittels soziotechnischer Konstruktions- und Veränderungsprozesse und ist abhängig von Personen, deren Einstellungen, Erwartungen und Handlungen, ihrer Umwelt, ihrer Werte- und Normrahmungen sowie Veränderungen im Laufe der Zeit. Diese Parameter werden in der Debatte derzeit noch wenig beachtet. Verschiedene qualitative Methoden bilden die Grundlage für eine erste Exploration und Strukturierung des noch wenig bekannten Untersuchungsgegenstands. Die Ergebnisse zeigen, dass Akzeptanz des autonomen Fahrens wesentlich vom Zusammenspiel individueller und gesellschaftlicher Einflussfaktoren abhängt – die nicht alleine über Einstellungsparameter erfasst werden können. Sie lassen sich erst vor dem Hintergrund von handlungsleitenden, kollektiven Orientierungen zu aktuellen Autonutzungspraktiken verstehen. Gleichzeitig ist ein konsistenter, in sich geschlossener Entwicklungspfad zum autonomen Fahren derzeit noch nicht absehbar, und es sind einerseits Entwicklungen möglich, die das System der Mobilität grundlegend verändern könnten. Andererseits sind aber auch Veränderungen denkbar, die das bestehende System eher ergänzen, als es radikal zu transformieren. Vor diesem Hintergrund ergeben sich je spezifische Implikationen für die weitere Forschung. / Autonomous driving could fundamentally transform car use and ownership and considerably change the way how we interact with the automobile, how mobility and transport are organized in the future and how urban and transportation infrastructures are designed. The objective of this study is to engage empirical, social sciences in a timely and comprehensive debate on autonomous driving, so the key factors and dynamics of this technological development can be identified and shaped. Forecasting development trajectories of technology-based developments proves especially difficult, and acceptance is thought to be a key factor for a successful product implementation. Acceptance takes place in the context of sociotechnical construction and transformation processes; it is dependent on individuals, their attitudes, expectations and actions, their environment, their value- and norm-framing, and on changes over time. User perception, evaluation and contextualization in relation to autonomous driving have largely gone unheeded, even though they are deemed central to technology acceptance. A set of distinct qualitative methods served to explore and structure a research topic little known to date. In sum, the results indicate that acceptance of autonomous driving fundamentally relies on the interaction of individual and societal factors that cannot be determined through attitudinal parameters only. They are better understood against the background of implicit and habitual orientations towards current car use and ownership practices. At the same time, the studies have shown that a consistent and determined development path cannot be predicted yet. While there are chances for the mobility system to undergo a fundamental transformation with the implementation of autonomous vehicles – on both supply and demand sides – potential changes could also rather complement the existing system. Specific implications for future research will be discussed in the thesis.
