- Background: Socioeconomic status (SES) can greatly affect the clinical outcome of medical problems. We sought to assess the in‑hospital mortality of patients with the acute coronarysyndrome (ACS) according to their SES.Methods: All patients admitted to Tehran Heart Center due to 1st‑time ACS between March 2004 and August 2011 were assessed. The patients who were illiterate/lowly educated (≤5 years attained education) and were unemployed were considered low‑SES patients and those who were employed and had high educational levels (>5 years attained education) were regarded as high‑SES patients. Demographic, clinical, paraclinical, and in‑hospital medical progress data were recorded. Death during the course of hospitalization was considered the end point, and the impact of SES on in‑hospital mortality was evaluated.Results: A total of 6246 hospitalized patients (3290 low SES and 2956 high SES) were included (mean age = 60.3 ± 12.1 years, male = 2772 [44.4%]). Among them, 79 (1.26%) patients died. Univariable analysis showed a significantly higher mortality rate in the low‑SES group (1.9% vs. 0.6%; P < 0.001). After adjustment for possible cofounders, SES still showed a significant effect on the in‑hospital mortality of the ACS patients in that the high‑SES patients had a lower in‑hospital mortality rate (odds ratio: 0.304, 95% confidence interval: 0.094–0.980; P = 0.046).Conclusions: This study found that patients with low SES were at a higher risk of in‑hospital mortality due to the ACS. Furthermore, the results suggest the need for increased availability of jobs as well as improved levels of education as preventive measures to curb the unfolding deaths owing to coronary artery syndrome.

- Human–computer interface was utilized to amplify the power of a hybrid algorithm that combines fuzzy logic, regression analysis, and non-linear optimization to extract knowledge from a roll pass design database. This strategy is applied to grooves with vertical and horizontal symmetry which are employed in initial passes to roll a broad range of steel products. The results presented here from the case study are both statistically significant and valid from the viewpoint of roll pass design theory. © 2015, Springer-Verlag London.

Global Supply Chain Design : Exploring configurational and coordination factors
- 2015
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis addresses the topic of global supply chain design. One major challenge concerns how to manage the tension between separation and integration pertaining to the localization of business activities. In this regard Ferdows (2008) worked to create two new production network models (rooted production network and footloose production network). Earlier studies have highlighted the choices that are involved in the network of facilities but lack in providing a comprehensive picture in terms of both configurational and coordination factors that govern the design of global supply chain. There is a need for a conceptual model where factors affecting the design process of a global supply chain can be applied. Two main research questions have been addressed in this study. First, exploring and identifying the factors affecting global supply chain design. Second, investigating the factors that influence the position on the spectrum of rooted and footloose supply chain design. A literature review analysis and multi-case studies have been performed for this study in order to explore the factors. The companies were selected in order to reflect upon the two types of network, i.e., rooted and footloose. The primary data were selected through interviews with the managers.This study highlighted that there are many factors that affect configurational and coordination decision areas within a global supply chain. This study categorized the factors and the configurational/coordination decision areas with two main competitive priorities, i.e., cost and differentiation in the form of a “conceptual model.” The study also highlighted the factors in a matrix, which showed their position on the spectrum of rooted and footloose network configurations. For instance, the coordination factors that drive towards a footloose network include: high orchestration capabilities, need access to new technology and knowledge, proximity to suppliers, etc. The configurational factors that drive towards a rooted network include: economic stability, proximity to market, concerns for sustainability issues, high transportation cost, need for high proximity between key functions, need for intellectual property rights protection, etc.

- Background: Human error and deficient non-technical skills (NTSs) among providers of ALS in helicopter emergency medical services (HEMS) is a threat to patient and operational safety. Skills can be improved through simulation-based training and assessment. Objective: To document the current level of simulation-based training and assessment of seven generic NTSs in crew members in the Norwegian HEMS. Methods: A cross-sectional survey, either electronic or paper-based, of all 207 physicians, HEMS crew members (HCMs) and pilots working in the civilian Norwegian HEMS (11 bases), between 8 May and 25 July 2012. Results: The response rate was 82% (n=193). A large proportion of each of the professional groups lacked simulation-based training and assessment of their NTSs. Compared with pilots and HCMs, physicians undergo statistically significantly less frequent simulation-based training and assessment of their NTSs. Fifty out of 82 (61%) physicians were on call for more than 72 consecutive hours on a regular basis. Of these, 79% did not have any training in coping with fatigue. In contrast, 72 out of 73 (99%) pilots and HCMs were on call for more than 3 days in a row. Of these, 54% did not have any training in coping with fatigue. Conclusions: Our study indicates a lack of simulation-based training and assessment. Pilots and HCMs train and are assessed more frequently than physicians. All professional groups are on call for extended hours, but receive limited training in how to cope with fatigue.

Tidskriftsartikel (refereegranskat)abstract
- According to Vening Meinesz-Moritz (VMM) global inverse isostatic problem, either the Moho density contrast (crust-mantle density contrast) or the Moho geometry can be estimated by solving a non-linear Fredholm integral equation of the first kind. Here solutions to the two Moho parameters are presented by combining the global geopotential model (GOCO-03S), topography (DTM2006) and a seismic crust model, the latter being the recent digital global crustal model (CRUST1.0) with a resolution of 1A(0)x1A(0). The numerical results show that the estimated Moho density contrast varies from 21 to 637 kg/m(3), with a global average of 321 kg/m(3), and the estimated Moho depth varies from 6 to 86 km with a global average of 24 km. Comparing the Moho density contrasts estimated using our leastsquares method and those derived by the CRUST1.0, CRUST2.0, and PREM models shows that our estimate agrees fairly well with CRUST1.0 model and rather poor with other models. The estimated Moho depths by our least-squares method and the CRUST1.0 model agree to 4.8 km in RMS and with the GEMMA1.0 based model to 6.3 km.

Coping with Cancer in Sweden : A Search for Meaning
- 2015. - 1
-
Bok (refereegranskat)abstract
- This book is based on triangulation research consisting of a sociological qualitative and quantitative study among people struck by cancer and a study conducted among nurses working in cancer care.The aim of the book is to present the results of these studies, in particular those of the quantitative study.The qualitative study aimed at identifying the religious and spiritually oriented coping methods used by cancer patients in Sweden, which serves as an example of societies in which religion is not an integrated part of the social life of individuals. The empirical data for the study were based on interviews with cancer patients. Fifty-one interviews were conducted in various parts of Sweden with patients suffering from different types of cancer. Concerning the use of religious and spiritually oriented methods by the Swedish informants, we learn that gaining control over the situation is a very important coping strategy for them. The informants show a strong tendency toward relying primarily on themselves for solving problems related to their disease. Receiving help from other sources, among others God or a supreme power, seems to primarily be a way to gain more power to help oneself, as opposed to passively waiting for a miracle. For the informants, thinking about spiritual matters and spiritual connection seems to be more important than participating in religious rituals and activities. Turning to nature as a sacred and available resource is a coping method that all informants have used, regardless of their outlook on God, their religion and philosophy of life or their age and gender. The qualitative study shows clearly the impact of culture on coping.The qualitative study on nurses focuses on coping among Swedish oncology nurses. The research questions were close to the coping theory (Pargament, 1997) that was used for interpretation. 1. How can the stress experienced by oncology nurses be described? (Ekedahl & Wengström, 2007) 2. Which functional and dysfunctional coping strategies do nurses use to cope with work-related stress? (Ekedahl & Wengström, 2006) 3. What religious components can be identified as coping resources in oncology nurses’ orienting system and what function does religiosity have in their work? (Ekedahl & Wengström, 2010) 4. How does culture influence the coping process through different coping styles? (Ekedahl, 2011; Ekedahl & Wengström, 2012)Four levels of stress were identified: the individual level of the nurse, a group level that is related to the team, an organizational level, and a cultural level. Nurses working in cancer care have to cope with different types of stress. They move from simpler types to the worst type of stress: multifaceted stress with an existential dimension. The most intensive stress is on the individual level and the group level, where the existential dimension is activated.Concerning the coping strategies, the dominant one is boundary demarcation. Lack of this important strategy is dysfunctional. Religious coping is dominated by basic trust and prayer and can provide support. Using concepts from cultural psychology, individualistic and collectivistic coping are suggested as additional coping styles.The aim of the quantitative study was to examine the extent to which the results obtained in the qualitative study among cancer patients, explained above, are applicable to a wider population of cancer patients in Sweden. In addition to questions relating to the former qualitative study, this survey also makes use of the RCOPE questionnaire (designed by Kenneth I Pargament) in designing the quantitative study. In this quantitative study, 5000 questionnaires were distributed among persons diagnosed with cancer; 2355 people responded. The results show that nature has been the most important coping method among cancer patients in Sweden.The highest mean value (2.9) is for the factor ‘nature has been an important resource to you in allowing you to deal with your illnesses.’ Two out of three respondents (68%) affirmed that this method helped them feel significantly better during or after their illness. The second highest average (2.8) is for the factor ‘listening to “natural music” (birdsong and the wind).’ Two out of three respondents (66%) answered that this coping method helped them feel significantly better during their illness. The third highest average (2.7) is for the factor ‘walking or engaging in any activity outdoors gives you a spiritual sense.’ Concerning the role of nature as the most important coping method for cancer patients, this survey confirms the results obtained from the previous qualitative studies.Moreover, the results of the quantitative study indicate that few informants used religious coping methods, as they were inclined to trust their own abilities to solve problems more than other sources of power, such as God or a religious authority. This result may be partly due to the predominance of secularism in Swedish society and the strong position individualism plays in Swedish culture, which fosters the idea that individuals are responsible for tackling their own problems.

Tidskriftsartikel (refereegranskat)abstract
- The authors have conducted a quantitative survey to examine the extent to which the results obtained in a qualitative study among cancer patients in Sweden (Ahmadi, Culture, religion and spirituality in coping: The example of cancer patients in Sweden, Uppsala, Acta Universitatis Upsaliensis, 2006) are applicable to a wider population of cancer patients in this country. In addition to questions relating to the former qualitative study, this survey also references the RCOPE questionnaire (designed by Kenneth I Pargament) in the design of the new quantitative study. In this study, questionnaires were distributed among persons diagnosed with cancer; 2,355 people responded. The results show that nature has been the most important coping method among cancer patients in Sweden. The highest mean value (2.9) is the factor ‘nature has been an important resource to you so that you could deal with your illnesses’. Two out of three respondents (68 %) affirm that this method helped them feel significantly better during or after illness. The second highest average (2.8) is the factor ‘listening to ‘natural music’ (birdsong and the wind)’. Two out of three respondents (66 %) answered that this coping method significantly helped them feel better during illness. The third highest average (2.7) is the factor ‘to walk or engage in any activity outdoors gives you a spiritual sense’. This survey concerning the role of nature as the most important coping method for cancer patients confirms the result obtained from the previous qualitative studies.

Aesthetic learning processes
- 2015
-
Ingår i: 25th EECERA Annual conference 'Innovation, experimentation and adventure in early childhood'. ; , s. 271-271

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The aim with our ongoing research is to find out what primary school teacher students (working with 6-8 year old pupils) thought of the meaning of aesthetics in teaching. What are the benefits of an aesthetic learning process? Previous research that we refer to is the dissertation of Tarja Häikö (2007). She investigates how aestethic learning processes are used in school and preschools. Boberg & Högberg (2015) have investigated how aestethic learning processes are used in schools and teacher education. Chemi (2012) has investigated the relationship between art, emotions and learning. Our framework is socio-cultural theory in accordance with Vygotsky (1995). The work of Gardner (2009), Hethland (2013) and Lindström (2010 & 2012) provides us with tools for analysis. The work has an hermeneutic phenomenologic research approach, using narratives (poetry as method). The participants were informed of the study and its aims. The confidentiality of the informants was secured. Consequences for informants were considered. A story can be a powerful way of reporting the results in research. How about using an even more condensed form, like a poem? We assume that the poetic language communicates with the reader in a more sensitive way than other research languages. Can the creation of the haiku in itself be a tool for discovery? We hope that the students will became aware of the usefulness and meaning of aesthetic learning. We also hope for increased use of aesthetic learning processes in schools.
