- Objectives: To assess whether a psychosocial intervention teaching coping strategies to women can improve quality of life (QOL) in groups of Iranian women exposed to social pressures. Design: Quasi-experimental non-randomised group design involving two categories of Iranian women, each category represented by non-equivalent intervention and comparison groups. Setting: A large urban area in Iran. Participants: 44 women; 25 single mothers and 19 newly married women. Interventions: Seventh-month psychosocial intervention aimed at providing coping strategies. Primary outcome measures: Effect sizes in four specific health-related domains and two overall perceptions of QOL and health measured by the WHOQOL-BREF instrument. Results: Large effect sizes were observed among the women exposed to the intervention in the WHOQOLBREF subdomains measuring physical health (r=0.68; p<0.001), psychological health (r=0.72; p<0.001), social relationships (r=0.52; p<0.01), environmental health (r=0.55; p<0.01) and in the overall perception of QOL (r=0.72; p<0.001); the effect size regarding overall perception of health was between small and medium (r=0.20; not significant). Small and not statistically significant effect sizes were observed in the women provided with traditional social welfare services. Conclusions: Teaching coping strategies can improve the QOL of women in societies where gender discrimination is prevalent. The findings require reproduction in studies with a more rigorous design before the intervention model can be recommended for widespread distribution.

Tidskriftsartikel (refereegranskat)abstract
- Background. Grief is a normal phenomenon but showing great variation depending on cultural and personal features. Bonanno and Kaltman have nonetheless proposed five aspects of normal grief. The aim of this study was to investigate if women with miscarriage experience normal grief. Material and methods. Content analyses of 25 transcribed conversations with women 4 weeks after their early miscarriages were classified depending on the meaning-bearing units according to Bonanno and Kaltman's categories. In the factor analyses, these categories were compared with the Perinatal Grief Scale and women's age, number of children and number of miscarriages, and gestational weeks. Results. Women with miscarriage fulfill the criteria for having normal grief according to Bonanno and Kaltman. All of the 25 women had meaning-bearing units that were classified as cognitive disorganization, dysphoria, and health deficits, whereas disrupted social and occupational functioning and positive aspects of bereavement were represented in 22 of 25 women. From the factor analysis, there are no differences in the expression of the intensity of the grief, irrespective of whether or not the women were primiparous, younger, or had suffered a first miscarriage. Conclusion. Women's experience of grief after miscarriage is similar to general grief after death. After her loss, the woman must have the possibility of expressing and working through her grief before she can finish her pregnancy emotionally. The care-giver must facilitate this process and accept that the intensity of the grief is not dependent on the woman's age, or her number of earlier miscarriages.

Decision-making in the Requirements Engineering Process : A Human-centred Approach
- 2005
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Complex decision-making is a prominent aspect of requirements engineering and the need for improved decision support for requirements engineers has been identified by a number of authors. A first step toward better decision support in requirements engineering is to understand decision-makers’ complex decision situations. To gain a holistic perspective of the decision situation from a decision-makers perspective, a decision situation framework has been created. The framework evolved through a literature analysis of decision support systems and decision-making theories. The decision situation of requirements engineers has been studied at Ericsson Microwave Systems and is described in this thesis. Aspects of decision situations are decision matters, decision-making activities, and decision processes. Another aspect of decision situations is the factors that affect the decision-maker. A number of interrelated factors have been identified. Each factor consists of problems and these are related to decision-making theories. The consequences of this for requirements engineering decision support, represented as a list that consists of desirable high-level characteristics, are also discussed.

Envisioning a Future Decision Support System for Requirements Engineering : A Holistic and Human-centred Perspective
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Complex decision-making is a prominent aspect of requirements engineering (RE) and the need for improved decision support for RE decision-makers has been identified by a number of authors in the research literature. The fundamental viewpoint that permeates this thesis is that RE decision-making can be substantially improved by RE decision support systems (REDSS) based on the actual needs of RE decision-makers as well as the actual generic human decision-making activities that take place in the RE decision processes. Thus, a first step toward better decision support in requirements engineering is to understand complex decision situations of decision-makers. In order to gain a holistic view of the decision situation from a decision-maker’s perspective, a decision situation framework has been created. The framework evolved through an analysis of decision support systems literature and decision-making theories. The decision situation of RE decision-makers has been studied at a systems engineering company and is depicted in this thesis. These situations are described in terms of, for example, RE decision matters, RE decision-making activities, and RE decision processes. Factors that affect RE decision-makers are also identified. Each factor consists of problems and difficulties. Based on the empirical findings, a number of desirable characteristics of a visionary REDSS are suggested. Examples of characteristics are to reduce the cognitive load, to support creativity and idea generation, and to support decision communication. One or more guiding principles are proposed for each characteristic and available techniques are described. The purpose of the principles and techniques is to direct further efforts concerning how to find a solution that can fulfil the characteristic. Our contributions are intended to serve as a road map that can direct the efforts of researchers addressing RE decision-making and RE decision support problems. Our intention is to widen the scope and provide new lines of thought about how decision-making in RE can be supported and improved.

- Emergency medical care for seriously injured patients in war or warlike situations is highly important when it comes to soldiers' survival and morale. The Swedish Armed Forces sends nurses, who have limited experience of caring for injured personnel in the field, on a variety of international missions. The aim of this investigation was to identify the kind of criteria nurses rely on when assessing acute trauma and what factors are affecting the emergency care of injured soldiers. A phenomenographic research approach based on interviews was used. The database for the study consists of twelve nurses who served in Bosnia in 1994-1996. The criteria nurses rely on, when assessing acute trauma in emergency care, could be described in terms of domain-specific criteria such as a physiological, an anatomical, a causal and a holistic approach as well as contextual criteria such as being able to communicate, having a sense of belonging, the military environment, the conscript medical orderly and familiarity with health-caring activity. The present study shows that the specific contextual factors affecting emergency care in the field must also be practised before the nurse faces military emergency care situations. This calls for realistic exercises and training programs, where experience from civilian emergency care is interwoven with the knowledge specific to military medical care. © 2007 Elsevier Ltd.

Tidskriftsartikel (refereegranskat)abstract
- Hydrogels are used in a wide range of biomedical applications, including three-dimensional (3D) cell culture, cell therapy and bioprinting. To enable processing using advanced additive fabrication techniques and to mimic the dynamic nature of the extracellular matrix (ECM), the properties of the hydrogels must be possible to tailor and change over time with high precision. The design of hydrogels that are both structurally and functionally dynamic, while providing necessary mechanical support is challenging using conventional synthesis techniques. Here, we show a modular and 3D printable hydrogel system that combines a robust but tunable covalent bioorthogonal cross-linking strategy with specific peptide-folding mediated interactions for dynamic modulation of cross-linking and functionalization. The hyaluronan-based hydrogels were covalently cross-linked by strain-promoted alkyne-azide cycloaddition using multi-arm poly(ethylene glycol). In addition, a de novo designed helix-loop-helix peptide was conjugated to the hyaluronan backbone to enable specific peptide-folding modulation of cross-linking density and kinetics, and hydrogel functionality. An array of complementary peptides with different functionalities was developed and used as a toolbox for supramolecular tuning of cell-hydrogel interactions and for controlling enzyme-mediated biomineralization processes. The modular peptide system enabled dynamic modifications of the properties of 3D printed structures, demonstrating a novel route for design of more sophisticated bioinks for four-dimensional bioprinting. © 2020 The Author(s).

Should fast-food franchisees pursue entrepreneurial orientation?

Tidskriftsartikel (refereegranskat)abstract
- Although it is widely accepted that entrepreneurial orientation (EO) improves firm performance, scholars have advised that particular attention should be paid to the context. In this research, we investigate a less explored context of franchising where business systems and procedures are usually dictated to franchisees by franchisors. Therefore, whether a franchisor should allow franchisees to pursue EO (innovativeness, proactiveness, risk-taking, competitive aggressiveness, and autonomy) is not clear. In the context of franchising, the majority of prior studies have mainly focused on the employment of EO as a unidimensional construct and at the franchisor level. In this research, we take a bottom-up perspective and evaluate the impact of different dimensions of EO on franchisees’ performance. Our analysis of a multi-group of 183 restaurant franchisees located in Sweden and Iran reveals that only the pursuit of proactiveness and competitive aggressiveness improves a franchisee’s performance and other dimensions do not play a significant role in improving performance in this context.

- Epigenetics may play a central, yet unexplored, role in the profound changes that the maternal immune system undergoes during pregnancy and could be involved in the pregnancy-induced modulation of several autoimmune diseases. We investigated changes in the methylome in isolated circulating CD4(+) T-cells in non-pregnant and pregnant women, during the 1(st) and 2(nd) trimester, using the Illumina Infinium Human Methylation 450K array, and explored how these changes were related to autoimmune diseases that are known to be affected during pregnancy. Pregnancy was associated with several hundreds of methylation differences, particularly during the 2(nd) trimester. A network-based modular approach identified several genes, e.g., CD28, FYN, VAV1 and pathways related to T-cell signalling and activation, highlighting T-cell regulation as a central component of the observed methylation alterations. The identified pregnancy module was significantly enriched for disease-associated methylation changes related to multiple sclerosis, rheumatoid arthritis and systemic lupus erythematosus. A negative correlation between pregnancy-associated methylation changes and disease-associated changes was found for multiple sclerosis and rheumatoid arthritis, diseases that are known to improve during pregnancy whereas a positive correlation was found for systemic lupus erythematosus, a disease that instead worsens during pregnancy. Thus, the directionality of the observed changes is in line with the previously observed effect of pregnancy on disease activity. Our systems medicine approach supports the importance of the methylome in immune regulation of T-cells during pregnancy. Our findings highlight the relevance of using pregnancy as a model for understanding and identifying disease-related mechanisms involved in the modulation of autoimmune diseases.

A validated generally applicable approach using the systematic assessment of disease modules by GWAS reveals a multi-omic module strongly associated with risk factors in multiple sclerosis
- 2021
-
Ingår i: BMC Genomics. - : BioMed Central. - 1471-2164. ; 22:1

Tidskriftsartikel (refereegranskat)abstract
- Background: There exist few, if any, practical guidelines for predictive and falsifiable multi-omic data integration that systematically integrate existing knowledge. Disease modules are popular concepts for interpreting genome-wide studies in medicine but have so far not been systematically evaluated and may lead to corroborating multi-omic modules. Result: We assessed eight module identification methods in 57 previously published expression and methylation studies of 19 diseases using GWAS enrichment analysis. Next, we applied the same strategy for multi-omic integration of 20 datasets of multiple sclerosis (MS), and further validated the resulting module using both GWAS and risk-factor-associated genes from several independent cohorts. Our benchmark of modules showed that in immune-associated diseases modules inferred from clique-based methods were the most enriched for GWAS genes. The multi-omic case study using MS data revealed the robust identification of a module of 220 genes. Strikingly, most genes of the module were differentially methylated upon the action of one or several environmental risk factors in MS (n = 217, P = 10− 47) and were also independently validated for association with five different risk factors of MS, which further stressed the high genetic and epigenetic relevance of the module for MS. Conclusions: We believe our analysis provides a workflow for selecting modules and our benchmark study may help further improvement of disease module methods. Moreover, we also stress that our methodology is generally applicable for combining and assessing the performance of multi-omic approaches for complex diseases.
