  • Culture, Religion and Spirituality in Coping The Example of Cancer Patients in Sweden
  • 2006
  • Bok (populärvet., debatt m.m.)abstract
    • Recent research has shown significant associations (negative and positive) between religious and spiritual factors and mental health. Much of this research, however, has been conducted in the US, where religion is an integrated part of most people’s lives. Other studies on religious and spiritually oriented coping conducted outside the US have also focused on religious people. Yet many are non-believers, and many believers do not consider themselves religious, i.e. religion is not an important part of their life. There are also societies in which the dominant culture and ways of thinking dismiss the role of religion in people’s lives. Research on religious coping rarely takes these people into consideration. Thus, the following questions arise: How are religion and spirituality involved in coping when non-believers or non-religious people face difficult events? How do culture and ways of thinking affect people’s choice of religious and spiritual coping methods? Proceeding from a cultural approach to coping and health, this book attempts to address these questions by looking at the coping strategies of Swedish cancer patients.

  • Mångfaldsbarometern tio år av attitydmätningar i Sverige
  • 2015
  • Bok (övrigt vetenskapligt)abstract
    • Boken är en samling av de flesta texter som har publicerats i samband med Mångfaldsbarometern.I det första kapitlet redogör Fereshteh Ahmadi, Mehrdad Darvishpour och Irving Palm för resultat från Mångfaldsbarometern från 2005 – 2014 och även andra undersökningar. De presenterar också en sociologisk analys av insamlade data under tio år.I det andra kapitlet presenterar Orlando Mella de första årens resultat utifrån ett sociologiskt perspektiv, både teoretiskt och metodologiskt.I det tredje kapitlet förklarar Orlando Mella resultaten av sju års mätningar av attityder till mångfald, av mätningar av attityder mot mångfald och fastställer och tolkar vissa tendenser som stabila profiler.I det fjärde kapitlet fokuseras på mångfalden i arbetslivet. Den svenska välfärden är tydligt relaterad till invandring. Att underlätta för invandrare att få möjlighet till arbete och egen försörjning har ansetts viktigt för deras integrering i samhället. Invånarnas egna erfarenheter av kontakter med personer med utländsk bakgrund visar sig påverka befolkningens attityder liksom kön, ålder och utbildning.I det femte kapitlet behandlas problem kring integration. Mångfaldsbarometern 2009 som kompletterats med ett antal intervjuer visar att en stor andel av befolkningen har positiva erfarenheter av invandrare och menar att de skall ha samma rättigheter och möjligheter som den infödda befolkningen. Studien visar dock att den sociala toleransen har sina gränser och tycks förändras över tid.Kapitlen 6-15 består av de årliga rapporterna av Mångfaldsbarometern. I dessa rapporter hittar man statistik och förklaringar till de olika tabeller och figurer som presenteras. I slutet av boken presenteras en lista över en del viktiga artiklar som skrevs i massmedia om Mångfaldsbarometern.

  • Den svenske mannens gränsland Manlighet, nation och modernitet i Sven Lidmans Silfverstååhlsvit
  • 2011
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • This thesis deals with the nationalistic imaginary in the novels of Sven Lidman, published 1910–1913. The novels hold forth a conservative point-of-view that embraces the bourgeois ideal of masculinity and the idea of the healthy, Swedish rural way of life as opposed to the destructive metropolis. This dualism is part of a dichotomy that structures the novels. It also entails continuity/fragmentation, the Swedish/the foreign, men/women, activity/ passivity as well as masculinity/femininity and unmanliness.In the Silfverstååhl-cycle the protagonists are young men of a noble, Swedish family. They progress from lost and introspective youths to grown men who are deeply concerned with and engaged in society. They are different representatives of the Swedish man – the farmer, the business man, the explorer and the clergy man. What unites them is how their “coming of age” develops, how through trial and struggle they become stronger and prove worthy of the manly role they finally take on. This is a major principle of the bourgeois masculinity that is also closely connected to the national identity of the men.There is also an ambiguity concerning modernity. Throughout the novels a critique of modern society is formulated, that acknowledges the modern age but simultaneously takes on a prudent attitude towards modern society. There is no going back for the Swedish nation; the modern times have to be confronted. The present is very important since it is the time for scrutiny. The handling of the modern era takes place in the developing processes of the young men, who have to be careful not to get trapped in the modern whirlpool that threatens to shatter the human being. The past, the familiar and the rural anchorage that the family relation entitles, is a defense against the destructive forces of modernity. But the past is not completely beneficial. Even though the past is of major importance to the national identity of the protagonists, they have to be very careful not to delve too much into the past because of the risk of paralysis and effeminization. In the nationalistic narrative the present encapsulates the past and the future. The Swedish man has to navigate in the borderland of modernity.

  • Open to a select few? Matching partners and knowledge content for open innovation performance
  • 2015
  • Ingår i: Creativity and Innovation Management. - Wiley-Blackwell. - 0963-1690. ; 24:1, s. 72-86
  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose of the paper is to illuminate the costs and benefits of crossing firm boundaries in inbound open innovation (OI) by determining the relationships among partner types, knowledge content and performance. The empirical part of the study is based on a survey of OI collaborations answered by R&D managers in 415 Italian, Finnish and Swedish firms. The results show that the depth of collaboration with different partners (academic/consultants, value chain partners, competitors and firms in other industries) is positively related to innovation performance, whereas the number of different partners and size have negative effects. The main result is that the knowledge content of the collaboration moderates the performance outcomes and the negative impact of having too many different kinds of partners. This illustrates how successful firms use selective collaboration strategies characterized by linking explorative and exploitative knowledge content to specific partners, to leverage the benefits and limit the costs of knowledge boundary crossing processes.

  • Design and Characterization of RF-Power LDMOS Transistors
  • 2008
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • In mobile communication new applications like wireless internet and mobile video have increased the demand of data-rates. Therefore, new more wideband systems are being implemented. Power amplifiers in the base-stations that simultaneously handle these wideband signals for many terminals (handhelds) need to be highly linear with a considerable band-width.In the past decade LDMOS has been the dominating technology for use in these RF-power amplifiers. In this work LDMOS transistors possible to fabricate in a normal CMOS process have been optimized and analyzed for RF-power applications. Their non-linear behavior has been explored using load-pull measurements. The mechanisms of the non-linear input capacitance have been analyzed using 2D TCAD simulations. The investigation shows that the input capacitance is a large contributor to phase distortion in the transistor.Computational load-pull TCAD methods have been developed for analysis of RF-power devices in high-efficiency operation. Methods have been developed for class-F with harmonic loading and for bias-modulation. Load-pull measurements with drain-bias modulation in a novel measurement setup have also been conducted. The investigation shows that the combination of computational load-pull of physical transistor structures and direct measurement evaluation with modified load-pull is a viable alternative for future design of RF-power devices. Simulations and measurements on the designed LDMOS shows a 10 to 15 % increase in drain efficiency in mid-power range both in simulations and measurements. The computational load-pull method has also been used to investigate the power capability of LDMOS transistors on SOI. This study indicates that either a low-resistivity or high-resistivity substrate should be used in manufacturing of RF-power LDMOS transistors on SOI to achieve optimum efficiency. Based on a proper substrate selection these devices exhibit a 10 % higher drain-efficiency mainly due to lower dissipated power in the devices.

  • Psychosocial work factors and musculoskeletal pain a cross-sectional study among Swedish flight baggage handlers
  • 2015
  • Ingår i: BioMed Research International. - 2314-6133. ; 2015
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. Flight baggage handlers sort and load luggage to airplanes. This study aimed at investigating associations between psychosocial exposures and low back and shoulder musculoskeletal disorders (MSDs) among Swedish flight baggage handlers.Methods. A questionnaire addressing MSDs (Standardized Nordic Questionnaire) and psychosocial factors (Copenhagen Psychosocial Questionnaire, COPSOQ) was answered by 525 baggage handlers in six Swedish airports.Results. Low back (LBP) and shoulder pain (SP) was reported by 70% and 60%, respectively. Pain was reported to interfere with work (PIW) by 30% (low back) and 18% (shoulders), and intense pain (PINT) occurred in 34% and 28% of the population. Quality of leadership was the most dissatisfying psychosocial factor, while the most positive was social community at work. Low ratings in the combined domain Work organization and job content were significantly associated with PIW in both low back and shoulders (Adjusted Hazard Ratios 3.65 (95% CI 1.67-7.99) and 2.68 (1.09-6.61)) while lower ratings in the domain Interpersonal relations and leadership were associated with PIW LBP (HR 2.18 (1.06-4.49)) and PINT LBP and SP (HRs 1.95 (1.05-3.65) and 2.11 (1.08-4.12)).Conclusion. Severity of pain among flight baggage handlers was associated with psychosocial factors at work, suggesting that they may be a relevant target for intervention in this occupation.

  • Identified obstacles and prerequisites in telenurses’ work environment a modified Delphi study
  • 2017
  • Ingår i: BMC Health Services Research. - 1472-6963. ; 17:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Telenursing is an expanding part of healthcare, staffed with registered nurses whose work environment is typical of a call centre. Work-related stress has been shown to be a major problem in nurses’ work environments and of importance to the outcome of care, patient safety, nurse job satisfaction and burnout. Today, however, we have a limited understanding of and knowledge about the work environment for telenurses. The aim of the present study is to explore and reach consensus on perceived important obstacles and prerequisites in telenurses’ work environment.Methods: A modified Delphi design, using qualitative as well as quantitative data sequentially through three phases, was taken. Data were initially collected via semi-structured interviews (Phase I) and later using a web survey (Phase II-III) between March 2015 and March 2016.Results: The findings present a consensus view of telenurses’ experiences of important obstacles and prerequisites in their work environment. Central to the findings are the aspects of telenurses having a demanding work, cognitive fatigue and having no opportunity for recovery during the work shift was ranked as important obstacles. Highly ranked prerequisites for managing were being able to focus on one caller at a time, working in a calm and pleasant environment and having technical support 24/7.Conclusions: Managers need to enable telenurses to experience control in their work, provided with possibilities to control their work and to recover during work; shortening work time could improve their work environment. Limited possibilities to perform work might contribute to feelings of stress and inability to perform work.

  • On the Road to a Software Profession Students’ Experiences of Concepts and Thresholds
  • 2010
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Research has shown that there are gaps in knowledge between newly hired and experienced professionals and that some of these gaps are related to concepts, such as the concepts of object orientation. This problem, and the fact that most computer science majors want to work in the software industry, leads to questions regarding why these gaps exist and how students can be better prepared for their future careers. Against this background, this thesis addresses two theme-based perspectives that focus on students' views of concepts in Computer Science.The first theme-based perspective investigated the existence of potential Threshold Concepts in Computer Science. Such concepts should be troublesome, transformative, irreversible, and integrative. Qualitative methods have been mainly used and empirical data have been collected through semi-structured interviews, concept maps, and written stories. The results identified two Threshold Concepts, suggested several more, and then described the ways in which these concepts have transformed students.The second theme-based perspective took a phenomenographic approach to find the variation in how students understand concepts related to the software profession. Data were collected via semi-structured interviews. In one study the interviews were held in connection with role-playing where students took on the role of a newly hired programmer. The results show a variety of ways to experience the addressed phenomena in the student collective, ranging from superficial views that often have a practical nature to more sophisticated understandings that reflect a holistic approach, including a professional point of view.Educators can use the results to emphasize concepts that are important from students' perspectives. The phenomenographic outcome spaces can help teachers to reflect upon their own ways of seeing contrasted with student conceptions. I have indicated how variation theory can be applied to open more sophisticated ways of seeing, which in this context stresses the professional aspects to help students prepare for becoming professional software developers.

  • Students working with a large software system experiences and understandings
  • 2007
  • Licentiatavhandling (övrigt vetenskapligt)abstract
    • This monograph describes an empirical study with the overall aim of producing insights about how students experience the subject Computer Science and its learning environments, particularly programming and software engineering.The research takes a start in the students' world, from their perspective, using their stories, and hence, we have chosen a phenomenographic approach for our research. By interpreting the students' descriptions and experiences of various phenomena and situations, it is possible to gain knowledge about which different conceptions students can have and how teaching and the learning environment affect their understanding. In this study, we focus specifically on students' conceptions of aspects of object-oriented programming and their experiences of problem solving situations in connection with object-oriented system development.The questions posed enlighten and focus on the students' conceptions of both tangible and abstract concepts; the study investigates how students experienced a task concerning development in a specific software system, how they conceived the system itself, and how the students describe the system's plugin modules. Academic education in programming deals with abstract concepts, such as interfaces in the programming language Java. Hence, one of the questions in this study is how students describe that specific abstract concept, in a context where they are conducting a realistic software engineering task.The results show that there is a distinct variation of descriptions, spanning from a concrete to-do list, to a more advanced description where the interface plays a crucial role in order to produce dynamic and adaptive systems. The discussion interprets the results and suggests how we can use them in teaching to provide an extended and varied understanding, where the educational goal is to provide for and strengthen the conditions for students to be able to learn how to develop and understand advanced software.
