- A Frequency Selective Surface (FSS) reflector with wideband response for 4G/X-band/Ku-band is proposed. The wideband FSS reflector consists of cascaded dual-layer patch FSS which is etched on separate layers of FR4 substrate. The targeted frequency range is 5–16 GHz. A wide stopband of 10.4 GHz (100% percent bandwidth) is obtained with two layers in cascade. The Equivalent Circuit (EC) method is used to approximate the simulated results. An extensive parametric study is also carried out to understand the effect of various combinations of FSS layers and their disposition. A panel of final FSS is fabricated where measured and simulated results agree well.

- Background Diverse ethnic groups may differ regarding the risk factors and severity of coronary artery disease (CAD). This study sought to assess the association between ethnicity and CAD risk and severity in six major Iranian ethnic groups.Methods In this study, 20,165 documented coronary artery disease patients who underwent coronary angiography at a tertiary referral heart center were recruited. The demographic, laboratory, clinical, and risk factor data of all the patients were retrieved. The Gensini score (an indicator of CAD severity) was calculated for all, and the risk factors and severity of CAD were compared between the ethnical groups, using adjusted standardized residuals, Kruskal–Wallis test, and multivariable regression analysis.Results The mean age of the participants (14,131 [70.1%] men and 6034 [29.9%] women) was 60.7 ± 10.8 years. The Fars (8.7%) and Gilak (8.6%) ethnic groups had the highest prevalence of ≥4 simultaneous risk factors. The mean Gensini score was the highest for the Gilaks (77.1 ± 55.9) and the lowest among the Lors (67.5 ± 52.8). The multivariable regression analysis showed that the Gilaks had the worst severity (β 0.056, 95% CI 0.009 to 0.102; P = 0.018), followed by the Torks (β 0.032, 95% CI 0.005 to 0.059; P = 0.020). Meanwhile, the Lors showed the lowest severity (β −0.087, 95% CI −0.146 to −0.027; P = 0.004).Conclusions This study found that there was heterogeneity in CAD severity and a diverse distribution in its well-known traditional risk factors among major Iranian ethnic groups.

- Higher education institutions (HEIs) play a major role in the development of societies. In the last decades, there has been an increasing interest on the commercialisation of knowledge by universities for economic development that lead to the emergence of the term “Entrepreneurial University”. This study aims to report the sustainability efforts of the University of Gävle, Sweden by applying a systematic tool, Graphical Assessment of Sustainability in Universities (GASU). This study highlights sustainability reporting as a way to improve communication practices between universities and stakeholder. The systematic and holistic assessment of HEIs gives insights of collaboration opportunities and by that foster their entrepreneurial journey.

Reshoring decision support in a Swedish context
- 2018
-
Konferensbidrag (refereegranskat)abstract
- This paper presents a decision-support system for reshoring decision-making based on fuzzy logic. The construction and functionality of the decision-support system are described, and the functionality is evaluated in a high cost environment exemplified through a Swedish context. Ten different reshoring scenarios, provided by Swedish reshoring experts, are entered into the decision-support system and the decision recommendations provided by the system are presented. The confidence that can be put on the recommendations is demonstrated by comparing them with those of the reshoring experts. The positive results obtained indicate that fuzzy logic is both feasible and that the quality of the results are sufficiently good for reshoring decision-making.

Konferensbidrag (refereegranskat)abstract
- BackgroundThere is an increased global interest in occupational health across small businesses as they represent a large share of employers in many societies. In the model of healthy work organisations, employee health is a prerequisite for higher productivity and profitability and management practices are considered as determinants of organisational health. A better understanding of how managers in effective companies use their time can offer a better understanding of how this can affect employees’ well-being and business effect-iveness. Managers’ long working hours and share of time spent on Management by Walking Around (MBWA) are considered important characteristics of managers’ work that might have consequences for employees’ and managers’ own health outcomes, as well as for organisational effectiveness. MBWA is a management technique common for successful companies in regard to their effectiveness; providing an opportunity for a spontaneous manager-subordinate interaction that might be important for employee health and wellbeing. Studies of managerial work have to some extent not clearly placed managers’ time use in the broad context of leadership, often missing to link it with leadership behaviour theories, health and effectiveness.ObjectiveThe objective of this study was to explore, on the one hand, the total amount of working hours that managers spent, and on the other, their patterns of time allocation to different activities in effective SMEs. Research questions were: 1) What patterns regarding managers’ working hours can be identified across socio-demographic variables, leader-ship experience factors and leadership profiles in effective SMEs? 2) What patterns regarding proportions of total working hours spent on MBWA can be identified across socio-demographic variables, leadership experience factors and leadership profiles in effective SMEs?MethodThe study used data collected within the project, “Successful Companies in Gästrikland”. Annually the project nominates 120 companies for the award based on companies’ financial indicators. The study employed a cross-sectional design and analysed responses to questionnaires collected within the project during years 2014-2018. The inclusion criteria were small and medium sized companies (more than four and less than 250 subordinates), high-level managers having subordinates. Data analysis were carried out using descriptive statistics and regression analysis.ResultsThe results section is being processed and will be reported on the conference.

Meaning-Making Methods for Coping with Serious Illness
- 2018
-
Bok (refereegranskat)abstract
- This book provides an alternative, complementary approach to the existing conventional approaches to religious and spiritually oriented coping. By focusing on the role of culture, the authors take into account the methods employed by a vast number of people who do not directly identify themselves as religious. The empirical data used in this book derive from studies conducted in several countries; Sweden, China, South Korea, Turkey and Malaysia, across which religion plays a different role in the social and cultural life of individuals. This approach and these empirical data are unique and allow comparisons to be made between different cultural settings.By introducing the concept of meaning-making coping, the authors explore the influence of culture on choice of coping methods, be they purely religious, spiritual or existential. The term "existential meaning-making coping" is used to describe coping methods that are related to existential questions; these methods include religious, spiritual and existential coping methods.Meaning-making Methods for Coping with Serious Illness contributes to new approaches and theoretical models of coping. As such it is an invaluable resource for health care, medical, public health and sociology students and researchers. It will also be of interest to educators and policy-makers working in the area of health.

Tidskriftsartikel (refereegranskat)abstract
- The present article is based on an international study on meaning-making coping aimed at understanding the role of culture in coping. The larger study has been conducted among cancer patients in 10 countries. The present article is confined to the results obtained in our study in Iran and restricted to religious coping methods. Twenty-seven participants with various kinds of cancer were interviewed. The several religious coping methods found in the present study are categorised on the basis of RCOPE?s five basic religious functions. The study reveals, among others, the impact of cultural beliefs on certain religious coping methods, even among those who are not regarded as practicing Muslims. The study highlights the importance of investigating cultural and social context when exploring the use of the meaning-making coping strategies in different countries.
