Research review (peer-reviewed)abstract
- A key concept in research on the media coverage of politics is the game or strategy frame. Contrasted with coverage of politics as issues, theframing of politics as a strategic game is marked by features such as winning and losing as the central concern and a focus on how candidates or parties are doing in opinion polls. The pervasiveness of such framing is, however, disputed since (1) the way in which the frames are conceptualized and operationalized differs significantly; and (2) while some use terms such as 'game frame' and 'strategy frame' as synonymous, others argue that there is a conceptual difference between them. Against this background, this article reviews research on the media's framing ofpolitics as a strategic game, what concepts have been used, and how they have been operationalized; and suggests a synthesis and ways of improving conceptual clarity and comparability in research on the media's use of strategy and/or game frames. © SAGE Publications 2011.

Staff and student perspectives and effects of positive behaviour support : a literature review
- 2023
-
In: Educational Psychology in Practice. - : Informa UK Limited. - 0266-7363 .- 1469-5839.
-
Research review (peer-reviewed)abstract
- Positive behaviour support (PBS) has been receiving increased attention recently but has not been studied from the perspectives of staff and students in Sweden. This article presents an integrative and systematic literature review focusing on international research concerning staff and student perspectives on the effects of PBS. The aim was to describe staff and student perspectives regarding PBS and its effects, between 2000 and 2022. The findings indicate that there is a lack of empirical research involving the combination of staff and student perspectives of the effects of PBS. The existing research is mostly from elementary schools age range 6 to 13. However, the findings suggest that there have been several studies that aim to gain a better understanding of teachers’ and students’ perspectives of how PBS enhances student social relationships, lowers problem behaviour and increases academic performance. According to the current findings, the success of the PBS approach is greatly influenced by the efficacy of execution and the leadership of the schools support for implementation.

Combinations of Aminocatalysts and Metal Catalysts : A Powerful Cooperative Approach in Selective Organic Synthesis
- 2016
-
In: Chemical Reviews. - : American Chemical Society (ACS). - 0009-2665 .- 1520-6890. ; 116:22, s. 13512-13570

Research review (peer-reviewed)abstract
- The cooperation and interplay between organic and metal catalyst Arninocatalysis systems is of utmost importance in nature and chemical synthesis. Here innovative and selective cooperative catalyst systems can be designed by combining two catalysts that complement rather than inhibit one another. This refined strategy can permit chemical transformations unmanageable by either of the catalysts alone. This review summarizes innovations and developments in selective organic synthesis that have used cooperative dual catalysis by combining simple aminocatalysts with metal catalysts. Considerable efforts have been devoted to this fruitful field. This emerging area employs the different activation modes of amine and metal catalysts as a platform to address challenging reactions. Here, aminocatalysis (e.g., enamine activation catalysis, iminium activation catalysis, single occupied molecular orbital (SOMO) activation catalysis, and photoredox activation catalysis) is employed to activate unreactive carbonyl substrates. The transition metal catalyst complements by activating a variety of substrates through a range of interactions (e.g., electrophilic pi-allyl complex formation, Lewis acid activation, allenylidene complex formation, photoredox activation, C-H activation, etc.), and thereby novel concepts within catalysis are created. The inclusion of heterogeneous catalysis strategies allows for green chemistry development, catalyst recyclability, and the more eco-friendly synthesis of valuable compounds.

Self-help and self-help groups for people with long-lasting health problems or mental health difficulties in a Nordic context : A review
- 2011
-
In: Scandinavian Journal of Public Health. - : SAGE Publications. - 1403-4948 .- 1651-1905. ; 39:8, s. 813-822
-
Research review (peer-reviewed)abstract
- Aim: The aim of this review is to provide systematic knowledge of research from Nordic countries about the meaning of self-help and self-help groups when these are used as a concept or method addressing issues related to long-lasting health problems or mental health difficulties. Methods: Included were studies conducted in the Nordic countries that were published between January 1999 and September 2009. These studies investigated self-help and self-help groups addressing issues related to long-lasting health problems. Results: A total of 83 publications met the inclusion criteria. Four major characteristics of self-help were found to be present in the publications: self-help as an intrapsychological process, self-help as an interpsychological or group process, self-help as a coping, individual learning or empowerment process, and self-help as an alternative or complement to medical treatment. Of the 83 studies, 72 publications used a professional treatment perspective for studying self-help and 11 publications used a perspective derived from alternative or complementary therapies. Conclusions: The review shows that most of the research on self-help and self-help groups for people with long-lasting health problems or disability is conducted with an interest to improve the professional healthcare system. That is, the health-promotion strategy is mainly considered in the framework of treatment or care settings. This means that self-help in this context does not challenge the dominant biomedical health model. © 2011 the Nordic Societies of Public Health.

Silicon Nanowires for Gas Sensing : A Review
- 2020
-
In: Nanomaterials. - : MDPI AG. - 2079-4991. ; 10:11
-
Research review (peer-reviewed)abstract
- The unique electronic properties of semiconductor nanowires, in particular silicon nanowires (SiNWs), are attractive for the label-free, real-time, and sensitive detection of various gases. Therefore, over the past two decades, extensive efforts have been made to study the gas sensing function of NWs. This review article presents the recent developments related to the applications of SiNWs for gas sensing. The content begins with the two basic synthesis approaches (top-down and bottom-up) whereby the advantages and disadvantages of each approach have been discussed. Afterwards, the basic sensing mechanism of SiNWs for both resistor and field effect transistor designs have been briefly described whereby the sensitivity and selectivity to gases after different functionalization methods have been further presented. In the final words, the challenges and future opportunities of SiNWs for gas sensing have been discussed.

Does in utero exposure to synthetic glucocorticoids influence birthweight, head circumference and birth length? : A systematic review of current evidence in humans
- 2011
-
In: Paediatric and Perinatal Epidemiology. - : Wiley. - 0269-5022 .- 1365-3016. ; 25:1, s. 20-36
-
Research review (peer-reviewed)abstract
- Synthetic glucocorticoids are the mainstay treatment for stimulating lung maturation in threatened preterm delivery. Animal studies suggest that in utero exposure to glucocorticoids leads to a reduction in birth size. Smaller birthweight has been associated with higher risk of many chronic diseases. Therefore, the authors undertook a systematic review of human studies examining the association between synthetic glucocorticoid treatment and birth size. Medline, EMBASE, PubMed, Cochrane, Google scholar and Institute of Life Science databases were searched for studies published between 1978 and 2009 investigating the association between synthetic glucocorticoids and birthweight, head circumference, birth length and ponderal index. All studies controlling for gestational age were examined. Seventeen studies were included in the analysis. Nine out of 17 studies reported a reduction in birthweight (range 12-332 g), five of nine a reduction of head circumference (range 0.31-1.02 cm) and two of four a reduction of 0.8 cm in birth length. Despite methodological inconsistencies and limitations that impede clear conclusions, the evidence suggests an association between in utero exposure to synthetic glucocorticoids and reduced birth size.

Megapixels @ Megahertz – The AGIPD high-speed cameras for the European XFEL
- 2019
-
In: Nuclear Instruments and Methods in Physics Research Section A. - : Elsevier BV. - 0168-9002 .- 1872-9576. ; 942
-
Research review (peer-reviewed)abstract
- The European XFEL is an extremely brilliant Free Electron Laser Source with a very demanding pulse structure: trains of 2700 X-ray pulses are repeated at 10Hz. The pulses inside the train are spaced by 220ns and each one contains up to 1012photons of 12.4keV, while being ≤100fs in length. AGIPD, the Adaptive Gain Integrating Pixel Detector, is a hybrid pixel detector developed by DESY, PSI, and the Universities of Bonn and Hamburg to cope with these properties. It is a fast, low noise integrating detector, with single photon sensitivity (for Eγ⪆6keV) and a large dynamic range, up to 104 photons at 12.4keV. This is achieved with a charge sensitive amplifier with 3 adaptively selected gains per pixel. 352 images can be recorded at up to 6.5MHz and stored in the in-pixel analogue memory and read out between pulse trains. The core component of this detector is the AGIPD ASIC, which consists of 64 × 64 pixels of 200µm×200µm. Control of the ASIC's image acquisition and analogue readout is via a command based interface. FPGA based electronic boards, controlling ASIC operation, image digitisation and 10GE data transmission interface AGIPD detectors to DAQ and control systems. An AGIPD 1Mpixel detector has been installed at the SPB1 experimental station in August 2017, while a second one is currently commissioned for the MID 2 endstation. A larger (4Mpixel) AGIPD detector and one to employ Hi-Z sensor material to efficiently register photons up to Eγ≈25keV are currently under construction.

A Cognitive Behavioral Model Proposing That Clinical Burnout May Maintain Itself
- 2021
-
In: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 16:7
-
Research review (peer-reviewed)abstract
- Burnout is common in many countries and is associated with several other problems such as depression, anxiety, insomnia, and memory deficits, and prospectively it predicts long-term sick-leave, cardiovascular disease, and death. Clinical burnout or its residual symptoms often last several years and a common assumption is that recovery takes a long time by nature, despite full time sick-leave and the absence of work stress. The literature suggests models that hypothetically explain the development, but not maintenance, of the syndrome. Based on cognitive and behavioral principles, stress research, and stress theories, this paper describes a theoretical model explaining how clinical burnout can develop and be maintained. While the development of clinical burnout is mainly explained by prolonged stress reactions and disturbed recovery processes due to work related stressors, maintenance of the syndrome is particularly explained by prolonged stress reactions and disturbed recovery processes due to the new context of experiencing burnout and being on sick-leave. Worry about acquired memory deficits, passivity and excessive sleep, shame, fear of stress reactions, and the perception of not being safe are examples of responses that can contribute to the maintenance. The model has important implications for research and how to intervene in clinical burnout. For example, it can offer support to professional care providers and patients in terms of focusing on, identifying, and changing current contextual factors and behaviors that maintain the individual’s clinical burnout symptoms and by that facilitate burnout recovery. Regarding research, the model provides a highly important reason for researchers to study contextual factors and behaviors that contribute to the maintenance of clinical burnout, which has been neglected in research.

Fear of hypoglycaemia in adults with type 1 diabetes
- 2010
-
In: Diabetic Medicine. - : Wiley. - 0742-3071 .- 1464-5491. ; 27:10, s. 1151-8
-
Research review (peer-reviewed)abstract
- Aims The aim of this study was to examine the fear of hypoglycaemia and its association with demographic and disease-specific variables in a large and unselective population of adult patients with Type 1 diabetes. Methods Questionnaires were sent by post to all patients with Type 1 diabetes who were identified in the local diabetes registries of two hospitals in Stockholm, Sweden (n = 1387). Fear of hypoglycaemia was measured using the Swedish Hypoglycaemia Fear Survey, the Worry subscale and the Aloneness subscale. Demographic variables and disease-specific factors were collected from patients' self reports and medical records. Univariate analysis and multiple stepwise linear regression analysis were used in the statistical analyses of the data. Results Seven hundred and sixty-four (55%) patients participated in the study (mean age 43.3 years and mean HbA(1c) 7.0%, normal < 5.0%). The Hypoglycaemia Fear Survey - Worry subscale was significantly associated with frequency of severe hypoglycaemia, number of symptoms during mild hypoglycaemia, gender, hypoglycaemic symptoms during hyperglycaemia and hypoglycaemic unawareness. The Hypoglycaemia Fear Survey - Aloneness subscale was significantly associated with frequency of severe hypoglycaemia, number of symptoms during mild hypoglycaemia, gender, frequency of mild hypoglycaemia, HbA(1c) , hypoglycaemic unawareness and visits to the emergency room because of severe hypoglycaemia. Fear of hypoglycaemia proved to be more prevalent in females and indicated a different pattern between genders in relation to factors associated with fear of hypoglycaemia. Conclusions This study identifies the frequency of severe hypoglycaemia as the most important factor associated with fear of hypoglycaemia. Moreover, for the first time, we document gender differences in fear of hypoglycaemia, suggesting that females are more affected by fear of hypoglycaemia than men.
