- The purpose of this paper is to explore themes and challenges in developing environmentally sustainable logistical activities. The approach is explorative with a cross sectional design that takes advantage of ten case studies out of selected logistics service providers (LSPs) operating primarily in the Scandinavian countries The findings illustrate the major themes by analyzing current and future activities in developing environmentally sustainable logistical activities. In addition, four categories of challenges are identified: customer priorities, managerial complexity, network imbalance, and technological and legislative uncertainties. It is concluded that there is a great need for a holistic perspective where LSPs and product owners together analyze and design future logistical setups The suggested holistic and integrative model, building on a three-dimensional concurrent engineering framework, provides new opportunities for research. Further research is needed to improve the interrelationship between LSPs and their customers in the development of sustainable logistical solutions This paper puts forward recommendations for the sustainable development of logistics by combining the results from the case studies with a review of related literature. This will be beneficial for managers and policy makers when they approach sustainable logistical challenges. The emergence and synthesis of themes and challenges are critical for a sustainable society. (C) 2016 Elsevier Ltd. All rights reserved

Templated electrodeposition as a scalable and surfactant-free approach to the synthesis of Au nanoparticles with tunable aspect ratios
- 2022
-
Ingår i: Nanoscale Advances. - : Royal Society of Chemistry. - 2516-0230. ; 4:11, s. 2452-2467

Tidskriftsartikel (refereegranskat)abstract
- A high-throughput method for the fabrication of ordered arrays of Au nanoparticles is presented. It is based on pulsed electrodeposition into porous anodic alumina templates. In contrast to many synthesis routes, it is cyanide-free, prior separation of the alumina template from the aluminium substrate is not required, and the use of contaminating surfactants/capping agents often found in colloidal synthesis is avoided. The aspect ratio of the nanoparticles can also be tuned by selecting an appropriate electrodeposition time. We show how to fabricate arrays of nanoparticles, both with branched bases and with hemispherical bases. Furthermore, we compare the different morphologies produced with electron microscopies and grazing-incidence synchrotron X-ray diffraction. We find the nanoparticles are polycrystalline in nature and are compressively strained perpendicular to the direction of growth, and expansively strained along the direction of growth. We discuss how this can produce dislocations and twinning defects that could be beneficial for catalysis.

A Genetic Algorithm for Optimizing Mobile Stroke Unit Deployment
- 2023
-
Ingår i: Procedia Computer Science. - : Elsevier. - 1877-0509. ; 225, s. 3536-3545
-
Tidskriftsartikel (refereegranskat)abstract
- A mobile stroke unit (MSU) is an advanced ambulance equipped with specialized technology and trained healthcare personnel to provide on-site diagnosis and treatment for stroke patients. Providing efficient access to healthcare (in a viable way) requires optimizing the placement of MSUs. In this study, we propose a time-efficient method based on a genetic algorithm (GA) to find the most suitable ambulance sites for the placement of MSUs (given the number of MSUs and a set of potential sites). We designed an efficient encoding scheme for the input data (the number of MSUs and potential sites) and developed custom selection, crossover, and mutation operators that are tailored according to the characteristics of the MSU allocation problem. We present a case study on the Southern Healthcare Region in Sweden to demonstrate the generality and robustness of our proposed GA method. Particularly, we demonstrate our method's flexibility and adaptability through a series of experiments across multiple settings. For the considered scenario, our proposed method outperforms the exhaustive search method by finding the best locations within 0.16, 1.44, and 10.09 minutes in the deployment of three MSUs, four MSUs, and five MSUs, resulting in 8.75x, 16.36x, and 24.77x faster performance, respectively. Furthermore, we validate the method's robustness by iterating GA multiple times and reporting its average fitness score (performance convergence). In addition, we show the effectiveness of our method by evaluating key hyperparameters, that is, population size, mutation rate, and the number of generations.

Tidskriftsartikel (refereegranskat)abstract
- The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014-2016 July) public. Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey; the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data-driven machine-learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from the SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS web site (www.sdss.org) has been updated for this release and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020 and will be followed by SDSS-V.

Accessibility Denied : Understanding Inaccessibility and Everyday Resistance to Inclusion for Persons with Disabilities
- 2022
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- This book explores the societal resistance to accessibility for persons with disabilities, and tries to set an example of how to study exclusion in a time when numerous policies promise inclusion. With 12 chapters organised in three parts, the book takes a comprehensive approach to accessibility, covering transport and communication, knowledge and education, law and organisation. Topics within a wide cross-disciplinary field are covered, including disability studies, social work, sociology, ethnology, social anthropology, and history. The main example is Sweden, with its implementation of the United Nations Convention on the Rights of Persons with Disabilities within the context of the Nordic welfare state. By identifying and discussing persistent social and cultural conditions as well as recurring situations and interactions that nurture resistance to advancing accessibility, despite various strong laws promoting it, the book’s conclusions are widely transferable. It argues for the value of alternating between methods, theoretical perspectives, and datasets to explore how new arenas, resources and technologies cause new accessibility concerns — and possibilities — for persons living with impairments. We need to be able to follow actors closely to uncover how they feel, act, and argue, but also to connect to wider discursive and institutional patterns and systems. This book will be of interest to scholars and students of disability studies, social work, sociology, ethnology, social anthropology, political science, and organisation studies.

- 2019
-
Ingår i: SAGE Open Medicine. - : Sage Publications. - 2050-3121. ; 7, s. 1-7
-
Tidskriftsartikel (refereegranskat)abstract
- Objectives: The aim of this study was to establish the top 10 research uncertainties in aortic dissection together with the patient organization Aortic Dissection Association Scandinavia using the James Lind Alliance concept. Methods: A pilot survey aiming to identify uncertainties sent to 12 patients was found to have high content validity (scale content validity index = 0.91). An online version of the survey was thereafter sent to 30 patients in Aortic Dissection Association Scandinavia and 45 caregivers in the field of aortic dissection. Research uncertainties of aortic dissection were gathered, collated and processed. Results: Together with research priorities retrieved from five different current guidelines, 94 uncertainties were expressed. A shortlist of 24 uncertainties remained after processing for the final workshop. After the priority-setting process, using facilitated group format technique, the ranked final top 10 research uncertainties included diagnostic tests for aortic dissection; patient information and care continuity; quality of life; endovascular and medical treatment; surgical complications; rehabilitation; psychological consequences; self-care; and how to improve prognosis. Conclusion: These ranked top 10 important research priorities may be used to justify specific research in aortic dissection and to inform healthcare research funding decisions.

Att lyssna till röster. Ett vidgat lyssnandebegrepp i ett didaktiskt perspektiv.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis has two points of departure and four main purposes. The first point of departure concerns the narrow perspective of the listening skill in Swedish. The first purpose is to show the lack of attention to the listening skill in research and mother tongue education in the Swedish compulsory school. Educational documents from 1842 to 2000 about Swedish as a school subject are examined from a historical perspective. Results from the study show that the listening skill is only slowly approaching the same status as talking, but standards for listening are still missing in the syllabus for Swedish. The second purpose is to determine a meaning for the concept of ’listen’ in the Swedish language. Results from the study outline three distinct meanings in the Swedish language: the perception of hearing, the constructing of meaning with attentive listening, and the metaphorical meaning in phrases such as “listening to voices”. Moreover, the concept of ‘listen’ covers a wide semantic field and the Swedish definition foregrounds three dimensions. The second point of departure concerns an extended notion of listening in classroom research. The empirical study is based on field observations and transcriptions of videotaped talk in interaction of eight Swedish white middle-class students in teacher education over a six-month period, with a tutor and an observer. The object of inquiry is the documented part of an earlier reception expressed in an open and explicit response: that is, ‘reported listening’. The Bakhtin (1984) concept of ‘voice’ is connected to the metaphorical meaning of the concept ‘listen’. With an extended notion of listening it is possible to describe all the kinds of voices which the participants listen to, respond to and speak with when they are in dialogue with themselves and are creating a voice of their own. The third purpose is to examine reported listening with regard to what voices and contextual resources the participants refer to: that is, ‘voice response’. The concept of ‘intertextuality’ is adopted as a method to identify this polyphony of voices in the classroom. Results from the study indicate that some of the students have a broad and some a narrow listening repertory. Six listening types emerge in the material and the group seems to be an important contributor to the individual’s dialogic learning. The fourth purpose is to examine reported listening with regard to how the participants use those voices: that is, ‘voice use’. Some rhetorical terms are adopted as a method to identify the student’s purpose in using different voices. Results from the study suggest that the voice use principally has an arguing function and that some of the students use several different functions and some use only a few in their listening profile. Four listening positions emerge in the material, namely the ‘questioner’, the ‘refiller’, the ‘synthesizer’ and the ‘inquirer’. The implications of these findings are discussed. Compared with the American listening tradition “Listening to Voices” represents an alternative theoretical framework with a sociocultural approach.

Tidskriftsartikel (refereegranskat)abstract
- Background: A parental mental illness affects all family members and should warrant a need for support.Aim: To investigate the extent to which psychiatric patients with underage children are the recipients of child-focused interventions and involved in interagency collaboration.Methods: Data were retrieved from a psychiatric services medical record database consisting of data regarding 29,972 individuals in southern Sweden and indicating the patients' main diagnoses, comorbidity, children below the age of 18, and child-focused interventions.Results: Among the patients surveyed, 12.9% had registered underage children. One-fourth of the patients received child-focused interventions from adult psychiatry, and out of these 30.7% were involved in interagency collaboration as compared to 7.7% without child-focused interventions. Overall, collaboration with child and adolescent psychiatric services was low for all main diagnoses. If a patient received child-focused interventions from psychiatric services, the likelihood of being involved in interagency collaboration was five times greater as compared to patients receiving no child-focused intervention when controlled for gender, main diagnosis, and inpatient care.Conclusions: Psychiatric services play a significant role in identifying the need for and initiating child-focused interventions in families with a parental mental illness, and need to develop and support strategies to enhance interagency collaboration with other welfare services.

Health Risks in Same-Sex Attracted Ugandan University Students : Evidence from Two Cross-Sectional Studies
- 2016

Ingår i: PLOS ONE. - : Public Library of Science. - 1932-6203. ; 11:3
-
Tidskriftsartikel (refereegranskat)abstract
- Widespread discrimination across much of sub-Saharan Africa against persons with same-sex sexuality, including recent attempts in Uganda to extend criminal sanctions against same-sex behavior, are likely to have profound effects on this group's health, health care access, and well-being. Yet knowledge of the prevalence of same-sex sexuality in this region is scarce. This study aimed to systematically examine prevalence of same-sex sexuality and related health risks in young Ugandan adults. We conducted two cross-sectional survey studies in south-western Uganda targeting student samples (n = 980, n = 1954) representing 80% and 72% of the entire undergraduate classes attending a university in 2005 and 2010, respectively. A questionnaire assessed items concerning same-sex sexuality (same-sex attraction/fantasies, same-sex sexual relations), mental health, substance use, experience of violence, risky sexual behavior, and sexual health counseling needs. Our findings showed that same-sex sexual attraction/fantasies and behavior were common among male and female students, with 10-25% reporting having sexual attraction/fantasies regarding persons of the same-sex, and 6-16% reporting same-sex sexual relations. Experiences of same-sex sexuality were associated with health risks, e.g. poor mental health (2010, AOR = 1.5; 95% CI: 1.0-2.3), sexual coercion (2010, AOR 2.9; CI: 1.9-4.6), and unmet sexual health counseling needs (2010, AOR 2.2; CI: 1.4-3.3). This first study of young adults in Uganda with same-sex sexuality found high levels of health needs but poor access to health care. Effective response is likely to require major shifts in current policy, efforts to reduce stigmatization, and reorientation of health services to better meet the needs of this vulnerable group of young people.
