- BACKGROUND Anxiety and depression are more prevalent in women with polycystic ovary syndrome (PCOS) than in those without this disorder. Possible confounding effects of overweight and obesity are suggested. The aim was to compare symptoms of anxiety and depression in women with PCOS and controls matched for age, body weight and body mass index (BMI). METHODS Women with PCOS (n = 30) and controls (n = 30) were recruited from the community. Persons with ongoing psychotropic medication were excluded. All potential participants underwent gynecological examination to confirm case-control status. Participants completed the self-reported versions of the Brief Scale for Anxiety (BSA-S) and Montgomery Asberg Depression Rating Scale (MADRS-S). RESULTS Women with PCOS had a higher BSA-S score compared with controls (median, range: 10.5, 1-24 versus 5.0, 0-28, P < 0.001). They scored higher on the following four individual symptoms: reduced sleep (2.0, 0-5 versus 0, 0-2, P < 0.001), worry (1.5, 0-4 versus 0, 0-6, P = 0.004), phobias (1, 0-4 versus 0, 0-3, P < 0.001), and pain (1, 0-3 versus 0, 0-2, P < 0.001). No statistical difference was demonstrated regarding MADRS-S scores (10.0, 0-27 versus 5.5, 0-24, P = 0.053). Only one of the nine MADRS-S symptoms, reduced sleep, which is also included in the BSA-S, differed between cases and controls. CONCLUSIONS Several anxiety symptoms distinguished women with PCOS from a control group matched on BMI. A better understanding of the symptoms is needed to identify and alleviate anxiety symptoms in this vulnerable group.

- CONTEXT: Affective symptoms are poorly understood in polycystic ovary syndrome (PCOS). Clinical signs of hyperandrogenism and high serum androgens are key features in PCOS, and women with PCOS are more likely to be overweight or obese, as well as insulin resistant. Further, PCOS is associated with high sympathetic nerve activity. OBJECTIVE: To elucidate if self-reported hirsutism, body mass index (BMI) and waistline, circulating sex steroids, sex hormone-binding globulin (SHBG), insulin sensitivity and sympathetic nerve activity are associated with depression and anxiety-related symptoms in women with PCOS. DESIGN AND METHODS: Seventy-two women with PCOS, aged 21-37 years, were recruited from the community. Hirsutism was self-reported using the Ferriman-Gallway score. Serum estrogens, sex steroid precursors, androgens and glucuronidated androgen metabolites were analyzed by gas and liquid chromatography/mass spectroscopy (GC-MS/LC-MS/MS) and SHBG by chemiluminiscent microparticle immunoassay (CMIA). Insulin sensitivity was measured with euglycemic hyperinsulinemic clamp. Sympathetic nerve activity was measured with microneurography. Symptoms of depression and anxiety were self-reported using the Montgomery Åsberg Depression Rating Scale (MADRS-S) and the Brief Scale for Anxiety (BSA-S). RESULTS: Circulating concentrations of testosterone (T) (P=0.026), free T (FT) (P=0.025), and androstane-3α 17β-diol-3glucuronide (3G) (P=0.029) were lower in women with depression symptoms of potential clinical relevance (MADR-S≥11). The odds of having a MADRS-S score ≥11 were higher with lower FT and 3G. No associations with BSA-S were noted. CONCLUSION: Lower circulating FT and 3G were associated with worse self-reported depression symptoms. The relationship between mental health, sex steroids and corresponding metabolites in PCOS requires further investigation.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Over the past few decades, business travel has increased substantially, with both individual and organizational consequences. Many larger companies and public authorities therefore attempt to implement policies, regulations and standardized routines for their travel. The concept of travel management describes such activities pursued on a professional basis, by employed travel managers. The purpose of this report is to investigate travel management in Sweden and, in particular, to examine business travel by train in relation to professional travel management. The report mainly draws on interviews with travel managers, but empirical data also include interviews with sales personnel at travel agencies and at SJ (the state-owned Swedish railway company), interviews with frequent business travellers, and travel policy documents. To begin with, six important tasks for a travel manager are identified: 1) developing and implementing a travel policy, 2) cooperating with a travel agency, 3) making agreements with suppliers, 4) creating standardized payment routines, 5) collecting and analyzing travel statistics, and 6) communicating and gaining support within the organization. These different tasks are then described and analyzed in some detail, and specific attention is given to how the railway as a transport system works in relation to the practice of travel management. Moreover, two separate chapters in the report examine business travel by train from the travellers’ perspective and how environmental considerations in travel management may promote travel by train.

- This paper examines the practice of corporate travel management, using an analytical distinction between managerial strategies based on control versus commitment. Control-oriented strategies use formal rules, surveillance and sanctions, whereas commitment-oriented strategies encourage employee involvement, responsibility and self-control. The study draws on interviews with travel managers and analysis of travel policy documents. Elements of both control- and commitment-based management were identified at all stages of the business travel process – when a decision to travel was taken, when travel and accommodation were booked, and after the trip – but to varying extents in different organizations. The balance between control and commitment was influenced by both internal and external factors. With regard to internal factors, organizational hierarchies and the professional status of both travel managers and travelers played an important role. Senior management support and corporate culture also had an impact. External factors were mainly related to the business travel market. The ‘hybrid’ character of this market, the pricing and marketing strategies of important suppliers, and the services provided by major business travel agencies often promoted control-oriented travel management. The study may inspire travel managers to reflect on and refine their concrete managerial practices as well as their broader management strategies.

Bokkapitel (refereegranskat)abstract
- Place attachments are emotional bonds that form between people and their physical surroundings. These connections are a powerful aspect of human life that inform our sense of identity, create meaning in our lives, facilitate community and influence action. Place attachments have bearing on such diverse issues as rootedness and belonging, placemaking and displacement, mobility and migration, intergroup conflict, civic engagement, social housing and urban redevelopment, natural resource management and global climate change. In this multidisciplinary book, Manzo and Devine-Wright draw together the latest thinking by leading scholars from around the globe, capturing important advancements in three areas: theory, methods and application. In a wide range of conceptual and applied ways, the authors critically review and challenge contemporary knowledge, identify significant advances and point to areas for future research. This volume offers the most current understandings about place attachment, a critical concept for the environmental social sciences and placemaking professions.

Retirement migration
- 2013

Ingår i: Encyclopedia of Global Human Migration. - Oxford : Wiley-Blackwell.

Bokkapitel (refereegranskat)abstract
- Retired persons migrate for several different reasons, even though the migration rate in general is lower for retirees than among younger persons (Bradley & Longino 2009). One common form of retiree migration is the return migration of former labor migrants to their previous home countries or home regions. Another form can be described as family-oriented migration, as retired parents move in order to be close to their children (Warnes 2009). However, in academic discourse, the term retirement migration, or sometimes international retirement migration (IRM), primarily refers to amenity-oriented migration among retired persons from the Western world who move, permanently or temporarily, to new home places in search for an improved quality of life (King et al. 2000; Migration Policy Institute 2006).Keywords: Central America; globalization; immigration; postcolonialism; social change

Travel time and working time : What business travellers do when they travel, and why
- 2012
-
Ingår i: Time and Society. - 0961-463X. ; 21:2, s. 203-222
-
Tidskriftsartikel (refereegranskat)abstract
- Many business travellers today use some of their travel time as working time. However, interviews with frequent business travellers and travel managers in Sweden show that individual travellers differ very much in their attitudes and practices regarding travel time and working time, and that employers generally make no explicit demands about work during travel time. Also, although travellers often appreciate having good working conditions while travelling, the first priority for many frequent travellers is to minimize time spent away from home and family, rather than to make productive use of their travel time.

The Active Phase of Palladium during Methane Oxidation

- The active phase of Pd during methane oxidation is a long- standing puzzle, which, if solved, could provide routes for design of improved catalysts. Here, density functional theory and in situ surface X-ray diffraction are used to identify and characterize atomic sites yielding high methane conversion. Calculations are performed for methane dissociation over a range of Pd and PdOx surfaces and reveal facile dissociation on either under-coordinated Pd sites in PdO(101) or metallic surfaces. The experiments show unambiguously that high methane conversion requires sufficiently thick PdO(101) films or metallic Pd, in full agreement with the calculations. The established link between high activity and atomic structure enables rational design of improved catalysts.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Women with polycystic ovary syndrome (PCOS) have symptoms of depression and anxiety and impaired health related quality of life (HRQoL). Here we test the post-hoc hypothesis that acupuncture and exercise improve depression and anxiety symptoms and HRQoL in PCOS women. METHODS: Seventy-two PCOS women were randomly assigned to 16 weeks of 1) acupuncture (n = 28); 2) exercise (n = 29); or 3) no intervention (control) (n = 15). Outcome measures included: change in Montgomery Asberg Depression Rating Scale (MADRS-S), Brief Scale for Anxiety (BSA-S), Swedish Short-Form 36 (SF-36), and PCOS Questionnaire (PCOSQ) scores from baseline to after 16-week intervention, and to 16-week post-intervention follow-up. RESULTS: A reduction in MADRS-S and BSA-S from baseline to 16-weeks post-intervention follow-up was observed for the acupuncture group. The SF-36 domains role physical, energy/vitality, general health perception and the mental component of summary scores improved in the acupuncture group after intervention and at follow-up. Within the exercise group the role physical decreased after treatment, while physical functioning and general health perception scores increased at follow-up. The emotion domain in the PCOSQ improved after 16-weeks of intervention within all three groups, and at follow-up in acupuncture and exercise groups. At follow-up, improvement in the infertility domain was observed within the exercise group. CONCLUSION: There was a modest improvement in depression and anxiety scores in women treated with acupuncture, and improved HRQoL scores were noted in both intervention groups. While not a primary focus of the trial, these data suggest continued investigation of mental health outcomes in women treated for PCOS.Trial registration numberClinicalTrials.gov Identifier: NCT00484705.
