- We assess the most popular maintenance approaches, i.e. strategies, policies, or philosophies, using a fuzzy multiple criteria decision making (MCDM) evaluation methodology. We illustrate with two examples how the suggested evaluation methodology identifies the most informative approach. Using the fuzzy MCDM, it would be possible to select in advance, the most informative (efficient) maintenance approach. Consequently, this leads to less planned replacements, and failures would be reduced to approximately zero and higher utilization of component life can be achieved. Thus, the maintenance department could contribute more to the business objectives throughout participating effectively in adding value to the production activities.

Older People in Persistent Pain : Nursing and Paramedical Staff Perceptions and Pain Management
- 2003

- Background. Persistent pain is a common problem for older people. Knowledge about how nursing and paramedical staff perceive these people and what they do to relieve the pain seems scarce. Aim. To explore nursing and paramedical staff perceptions of older people in persistent pain and their day-to-day management of pain. Methods. Interviews in Swedish with 52 nursing auxiliaries, Registered Nurses, physiotherapists and occupational therapists were collected from February to May 2000. The analysis was based on their stories (n = 150) about older people in persistent pain who received help in their own homes or in special accommodation. A typology of staff perceptions of pain in older people was developed. Activities to manage pain were examined using content analysis. Results. Respondents perceived the pain as real, exaggerated, trivial, care-related, endured, concealed, self-caused or inarticulate. Older people perceived as exaggerating the pain, those with care-related and self-caused pain evoked frustration in the staff, while those perceived as enduring their pain evoked satisfaction. Various strategies to manage pain were used: no activity, medication, mediating contacts, distracting activities, physical therapies, mobility, work in a gentle way, rest or relieving pressure on body part, and communication concerning pain. The activities differed between the types, as well as between staff with different professional backgrounds. Conclusion. Care and treatment provided by staff should be based on older people's needs rather than on staff attitudes and preferences. The typology revealed that staff perceived older people in pain as a heterogeneous group and that their perceptions affected the pain-relieving activities that were offered. It seems urgent to address how to handle pain in older people who never complain and those who complain a great deal, as well as how to handle pain in people with impaired communicative ability. Reflective discussions on feelings related to different individuals are needed.

A fully integrated 2.45 GHz 0.25 mu m CMOS power amplifier
- 2003

Konferensbidrag (refereegranskat)abstract
- A fully integrated differential class-AB power amplifier has been designed in a 0.25 um CMOS technology. It is intended for medium output power ranges such as Bluetooth class 1, and has an operating frequency of 2.45 GHz. By using two parallel output stages that can be switched on or off, a high efficiency can be achieved for both high and low output power levels. The simulated maximum output power is 22.7 dBm, while the maximum power-added efficiency is 22%.

Konferensbidrag (refereegranskat)abstract
- A previously developed computational model for 3D finite element simulations of wood during moisture changes is in the present work provided with a special-purpose graphical user interface. The software is designed to use a personal computer for the graphical user interface and to have possibility to use distributed computational resources for the simulation.

The Inclusion of Female PhD Students in Academia: A Case Study of a Swedish University Department
- 2003

Ingår i: Gender, Work and Organization. - : Blackwell Publishing. - 0968-6673 .- 1468-0432. ; 10:2, s. 154-174

Tidskriftsartikel (refereegranskat)abstract
- The article introduces a framework for understanding women's entry into the academic world and how it interacts with internal departmental structures and practices. It presents three specific strategies applied by a group of women to gain a doctorate and acceptance in their department. Few previous studies have stressed women's strategies to cope with the organizational setting in academia. The article draws on previous research on women in academia and how organizational characteristics influence women's careers. It is based on a case study of a Swedish university department. Sweden is often recognized for creating favourable working conditions for women. Yet the Swedish academic world is very male-dominated at the top and even the medium level. It is also more common than in many other Western countries that academics stay on at the department where they graduated. Therefore, a PhD is often a first step in a career within that department.

- Objective: to describe first-time-expectant fathers’ experiences of pregnancy.Design: an inductive method using narrative interview formand qualitative content textanalysis.The text of the transcriptswas coded and categorised.Settings and participants: seven first-time-expectant fathers living in a multicultural industrial town in southern Sweden were interviewed individually when their partner was in the 38th to 39thweek of pregnancy.Measurements and findings: all the fathers-to-be experienced some psychological, socialand/or physical change during the pregnancy. The main category, was ‘time of transition’. Eight categories were found under this. They were: ‘feelings of unreality, ‘insufficiency and inadequacy’, ‘exclusion’, ‘reality’, ‘social changes’, ‘physical changes’, ‘responsibility, and development’.Key conclusion: the fathers’-to-be special needs for support and encouragement durin gpregnancymay be as important as those of the mothers’-to-be. The caregiver needs to be as aware of and sensitive to these needs. However, before any interventions can be recommendedmore research is needed.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- All randomized controlled studies published in international peer-reviewed journals up to July 1999 were meta-analysed with the aim of studying the effect of psychosocial interventions on patients with drug dependence. Systematic literature searches were administered by SBU. In all 104 studies were screened and rated according to the 12 dimension quality score of SBU. The analyses in the chapter studied the effects on drug abuse and retention and aimed at specific domains of research; 1) efficacy of treatment of opiate abuse/ depen¬dence (n=24) containing 5.721 patients, 2) of cocaine abuse/dependence, 26 studies with 5.956 patients), 3) cannabis abuse, (7 studies with 707 patients), 4) of treatment methods for patients with mental illness and (9 studies), 5) residential treatment containing 9 studies and 4.867 patients, 6) finally for structure interventions with other outcome measures than drug use, 5 studies with 461 patients. A clinical methodological model elaborated from Wolberg´s (1988) classification, divided the interventions into three groups: ranging in therapist skills, goals and costs from a) supportive, b) reeducational to c) psychotherapeutic intervenetions. Effect sizes were calcylated using Hedge´s d and groups of interventions were weighted with the root of the variance. In opiate abuse re-educational and psycho-therapeutic interventions had a significant but low Wd of .23 and .29 respectively. Re-educational interventions only gained a significant but low effect size of Wd = .24 in treatment of cocaine abuse. Family therapies finally were efficient in the treatment of teenage cannabis abusers in with an intact family network. Supportive interventions, generally, were not effective. For retention as outcome measure, finally, psychotherapies had a significant medium effect size in retention of opiate abuse (Wd= .56, n=3.380) and a low but significant positive effect size in retention of cocaine abuse (Wd= .30, n=3.381).
