  • Rollator related pedestrian single accidents and collision events in Sweden
  • 2022
  • Ingår i: Traffic Safety Research (TSR). - : Lund University. - 2004-3082. ; 2
  • Tidskriftsartikel (refereegranskat)abstract
    • Rollators (four-wheel walkers in USA; zimmer frames in UK) are commonly used as mobility aids for the elderly and people with a variety of disabilities. Pedestrian rollator users are a sub-group of Vulnerable Road Users (VRUs), although this group is rarely recognised in traffic safety contexts. The aim of this study is to extract and analyse rollator related pedestrian accident and injury data in Sweden. The results will provide valuable insight into the risks and obstacles rollator users are exposed to in the traffic environment and may in the long term contribute to improving the mobility of this group. The current study is based on data from 2,020 accidents involving 2,305 persons extracted from the Swedish Traffic Accident Data Acquisition (STRADA) database. For consistency reasons, a subset of data (N = 745) was analysed in order to investigate the development of accidents over a period of 10 years. Thereafter, each accident in the whole data set was registered as either single or collision. The results show that the number of rollator accidents in Sweden increased by approximately 80% during 2007–2016. Females dominate the injury statistics of single accidents, collisions, as well as fatal outcome, which may be due to exposure and/or differences in physical characteristics. Single accidents are much more common than collisions (n=1,668 and n=352, respectively) and the injury consequences are at least as serious. Data from the present study have revealed that the frequency of minor injuries (ISS 1–3) is 4.3 times, moderate (ISS 4–8) 6.0 times and serious injuries (ISS 9–15) 8.9 times higher in single accidents than in collisions. Fatal injuries are, however, more common in collision events (33 in comparison to 8). The vast majority of single accidents (99%) was due to falls. Many of the single accidents (29%) were caused by ground level differences (typically a curb) or due to surface conditions (19%). Collisions involved cars, trucks or buses in 91% of cases, occurring predominantly in car parks (31%) and on (zebra) crossings (30%). In 54% of cases the vehicles reversed into the rollator. Abbreviated Injury Scale (AIS) 3+ injuries were dominated by head (36%) and torso (33%) injuries in collision events, and hip fractures (71%) in single accidents. The present study shows that further research into rollator user related accidents, both single accidents and collision events, is required. In order to introduce appropriate measures, future work should follow up on accident and injury developments and further improve the quality of mobility aid related accident data in general. Improved stability and design, proper training programmes, effective maintenance services, development of a supporting infrastructure would contribute to increased safety for rollator users.

  • Obstacles and risks in the traffic environment for users of powered wheelchairs in Sweden
  • 2021
  • Ingår i: Accident Analysis and Prevention. - : Elsevier. - 0001-4575 .- 1879-2057. ; 159
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: According to the European Union, fatal road accidents involving Vulnerable Road Users (VRUs) are equal in proportion to fatal car road accidents (46%). VRUs include individuals with mobility challenges such as the elderly and Powered Wheelchair (PWC) users. The aim of this interdisciplinary qualitative study was to identify obstacles and risks for PWC users by exploring their behaviour and experiences in traffic environments.Methods: Videos and in-depth interviews with 13 PWC users aged 20–66 were analysed for this study. The interviews and videos, which include real-life outdoor observations, originate from a qualitative study exploring experiences of PWC use on a daily basis in Sweden. Underlying causal factors to identified risks and obstacles were identified, based on human, vehicle (PWC) and environmental factors in accordance with the Haddon Matrix.Results: The results show significant potential for improvement within all three perspectives of the Haddon Matrix used in the analysis. Participants faced and dealt with various obstacles and risks in order to reach their destination. For example, this includes uneven surfaces, differences in ground levels, steep slopes, as well as interactions with other road users and the influence of weather conditions, resulting in PWC users constantly accommodating and coping with the shortcomings of the vehicle and the environment.Conclusions: There are still major challenges with regard to preventing obstacles and risks in the traffic environment for PWC users. To discern PWC users in traffic accident and injury data bases, a start would be to register type of aid used for persons involved in an accident. Furthermore, to emphasise PWC users’ role as VRUs, it may also be advantageous to describe them as drivers rather than users when navigating the traffic environment. Given the limited sample, further research covering more data from a broader perspective would be beneficial. By incorporating emerging knowledge of PWC users’ prerequisites and needs, and including them in research and traffic planning, the society will grow safer and more inclusive, and become better prepared for meeting future demands on accessibility from an aging population.

  • Constituting gender and gender equality through policy : the political of gender mainstreaming in the Swedish forest industry
  • 2018
  • Ingår i: Equality, Diversity and Inclusion. - : Emerald Group Publishing Limited. - 2040-7149 .- 2040-7157. ; 37:8, s. 763-779
  • Tidskriftsartikel (refereegranskat)abstract
    • PurposeIn Sweden, gender mainstreaming policies have a long political history. As part of the national gender equality strategy of the Swedish forest industry, the ten largest forestry companies committed themselves to gender mainstream their policies. Limiting the impact of policies and the agency of change, the purpose of this paper is to focus on the varied and conflicting meanings and constitution of the concepts, the problem and, in extent, the organisational realities of gender mainstreaming.Design/methodology/approachIn both, implementation and practice, gender mainstreaming posse challenges on various levels and by analysing these documents as practical texts from the WPR-approach. This paper explores constructions of gender and gender equality and their implications on the practice and the political of gender mainstreaming in a male-dominated primary industry.FindingsThe results show that the organisations themselves were not constituted as the subject of the policy but instead some of the individuals (women). The subject position of women represented in company policy was one of lacking skills and competences and in the need of help. Not only men and the masculine norms but organisational processes and structures were also generally invisible in the material. Power and conflict were mainly absent from the understanding of gender equality. Instead, consenting ideas of gender equality were the focus. Such conceptualisations of gender equality are beneficial for all risk concealing power structures and thereby limit the political space for change.Originality/valueBy highlighting the scale of policy and the significance of organisational contexts, the results indicate how gender and gender equality are constitutive through the governing technologies of neoliberal and market-oriented ideologies in policy – emphasising the further limiting of space for structural change and politicalization within the male-dominated organisations of Swedish forest industry.

  • Socio-techno-ecological transition dynamics in the re-territorialization of food production : the case of wild berries in Sweden
  • 2024
  • Ingår i: Sustainability Science. - : Springer. - 1862-4065 .- 1862-4057.
  • Tidskriftsartikel (refereegranskat)abstract
    • Recent geopolitical and economic crises underline the need for a European transition towards a more sustainable food system. Scholars and policymakers have called for a re-territorialization of food production to strike a better balance between local, regional and global value chains. This paper explores the role of re-territorialization through an analysis of the emergence, development and current transformation of the Swedish wild berry value chain. The analysis combines the multi-level perspective on sustainability transitions with a socio-techno-ecological system approach and draws on interviews, informal conversations, participant observations and a range of secondary sources. The resulting case narrative shows how processes of de-territorialization may result in regimes that fail to address sustainability potential and problems. It also highlights that processes of re-territorialization challenge established regimes by promoting niches that represent different, albeit complementary, value chain configurations. Apart from a rich empirical narrative that brings useful knowledge to stakeholders to the Swedish wild berry value chain, the paper contributes to the theoretical understanding re-territorialization, shows how the ecological dimension can be accounted for with the multi-level perspective on sustainability transitions and presents a number of general policy implications.

  • A study of establishment processes and entrepreneurial industry emergence in a Swedish region facing difficulties
  • 2008
  • Ingår i: 53rd International Council for Small Business World Conference. - Halifax, Canada : ICSB.
  • Konferensbidrag (refereegranskat)abstract
    • This paper explores establishment processes of a new industry located in a peripheral region of Sweden that is based upon old traditional industries in decline. Based on a qualitativestudy, we identify how actors within the new industry interact and intervene with the existing infrastructures and institutions that support the old local industry while trying to build new infrastructures. We identify key restricting and supporting mechanisms for theestablishment processes, with implications for policy and regional and entrepreneurship research.

  • Renewing industry cluster development via interregional industry-university links
  • 2011
  • Ingår i: International Journal of Innovation and Regional Development. - : InderScience Publishers. - 1753-0660 .- 1753-0679. ; 3:6, s. 604-631
  • Tidskriftsartikel (refereegranskat)abstract
    • The importance of developing regional industry clusters has grown alongside the need for industries and universities to be more interlinked. A regional automotive testing industry cluster, located in the north of Sweden, is the innovative empirical setting for this research paper. Following the logic of induction, it is discovered that as the regional industry reached a certain maturity, renewal was sought via developing links to universities within other regions in Sweden. A conceptual sensemaking lens is used to theorise upon the links thus formed and to develop new insights into regional industry renewal processes and interregional industry-university links. Practical insights stemming from the case are also explained, and future research directions provided.

  • When a new industry meets traditional and declining ones: An integrative approach towards dialectics and social movement theory in a model of regional industry emergence processes
  • 2010
  • Ingår i: Scandinavian Journal of Management. - : Elsevier BV. - 0956-5221 .- 1873-3387. ; 26:3, s. 290-308
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper takes an integrative approach towards dialectics and social movement theories in a model of regional industry emergence processes. Based on an inductive qualitative investigation we describe how a new industry emerges in a declining and peripheral region dominated by struggling and traditional local industry. The emanating model of regional industry emergence is based on four main processes; framing processes, movement mobilisation processes, inter-industry relational processes and dialectical processes, which together shape the emerging regional industry. This exemplifies how new regional industry mobilisation efforts provide an ‘anti-thesis' to traditional industry, and how established industry actors respond with contestation to protect their business concepts. Furthermore we illustrate how new industry actors reframe their concepts to complement dominating traditional industry and to overcome tensions and conflicts. Following dialectic interaction between new and traditional industry we noticed signs of acceptance and synthesis between the newly formed and old industry actors; ultimately resulting in a revitalisation of the region's traditional industry. As such, the paper makes a point of accounting for agency and productive conflict when understanding regional industry renewal and emergence.

  • Co-opetition dynamics – an outline for further inquiry
  • 2010
  • Ingår i: Competitiveness Review: An International Journal. - : Emerald Group Publishing Ltd. - 1059-5422 .- 2051-3143. ; 20:2, s. 194-214
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose – The purpose of this paper is to conceptually develop the understanding of co-opetitiondynamics and to enhance the conceptual clarity of co-opetition by developing a definition based onprevious research efforts.Design/methodology/approach – This conceptual paper integrates various approaches to theconcept co-opetition into a definition that holds for co-opetitive interactions across multiple levels.Different co-opetitive interactions and the resulting dynamics are discussed by drawing uponcompetition and cooperation theories. The paper concludes with an agenda for further research onco-opetition dynamics.Findings – The paper outlines how different types of co-opetitive interactions result in archetypicalsituations where the dynamics of co-opetition are present as well as where the dynamics of co-opetitionare missing due to a lack of balance between cooperation and competition. It notes four co-opetitiveforces: over-embedding, distancing, confronting, and colluding. These four forces drive developmenttowards situations without dynamics.Originality/value – This paper provides a conceptual understanding of co-opetition dynamics andwill reveal that in order to adequately account for co-opetition dynamics, a definition of co-opetitionmust analytically separate the cooperative and the competitive interaction inherent in co-opetition.

  • Group work and physics – characteristics, learning possibilities and patterns of interaction
  • 2011
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis explores group work in physics at university level. The guiding research interest is what happens in the students’ interactions during such (instructional) activities, focusing both on the physics content and group dynamics. The four collated papers are based on empirical data consisting of video and audio-recordings of seven groups of students solving physics problems concerning force and friction in Newtonian mechanics. The students belonged to the Engineering Physics and Bioengineering programmes at Chalmers University of Technology.In line with the guiding research interest, different facets of group work data were analysed using a multi-theoretic perspective at three levels with focus on the content, the context and the components. The three distinct approaches were based on different theoretical frameworks: phenomenography combined with variation theory, positioning theory, and conversation analysis. The results presented in this thesis relate to pedagogical characteristics of the learning situation, learning possibilities and patterns of interaction and all the analytical approaches contribute to all the aspects of the results. The purpose of this design was to achieve a deeper understanding of a complex empirical situation by offering several accounts that are analytically and theoretically differently grounded. The theoretical frameworks have been interpreted, and sometimesadapted, in order to offer analytical strength in reflecting essential facets of the empirical data with respect to the research interest. Each level of analysis uncovered new dimensions of the learning situation, potentially enabling a synthesis of different understandings of group work. This synthesis will inform and support instructional advice for the learning of physics.The results show that learning physics in small groups is a complex and nonlinear process where the students’ learning possibilities differ and have many levels. These learning possibilities take place simultaneously in group sessions and are interconnected, for example, developing through discussion the way of experiencing physics concepts, becoming and being part of a physics or an engineering community and interactively producing answers, as well as communicative and representational tools for learning.
