  • Risk-based ship security analysis – an approach based on civilian and military methods
  • 2012
  • Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The demands on maritime operations today are increasingly higher in terms of control, efficiency and cost. The margins for accidents and security incidents are therefore decreasing. In the area of ship safety the regulations, guidelines and methods have a history and culture of systematic research, development and implementation. In contrast, international security is highly politicized and therefore not as transparent. The result is that a tradition of ship security is not as well established.The overall aim of this thesis is to propose a method for ship security analysis that increases the overall safety of the crew and the ship. The objective is to develop a method that is systematic in order to ensure that assessment and response are complete and effective, and that the process is documented to provide evidence of decision-making.The method used is probabilistic risk assessment where quantitative analysis is central. The proposed approach is consistent with the requirements of maritime safety work. However, in the work here, the proposed methods are specifically tested for security cases. This is because hazards (without intent) and threats (with intent) evolve in different ways into risk. Therefore, they must be analysed differently in order to capture the causal relationship.The proposed approach consists of three steps: the first step consists of a threat description that documents qualitative and quantitative aspects that together describe how the threat most likely will act in relation to the ship’s vulnerability; the second step uses the threat description to define the system studied as well as the scenarios that collectively describe the harmful consequences; the third step evaluates the risk with tools from probabilistic risk assessment.The overall conclusion is that the proposed method brings the procedure and results of ship security analysis into the open and therefore allows for criticism, improvements and shared risk knowledge, not possible with less structured methods. The results also show that the calculated probabilities agree with available statistics, which indicates that the analysis succeeds in describing the central causal relationships of the scenarios modelled.

  • The actors and their roles in the meaning making process of an energy target
  • 2012
  • Ingår i: 28th Annual Conference of the Association of Researchers in Construction Management,, ARCOM. Edinburgh, September 3-5 2012, p 851-861. - 9780955239069 ; Vol 2, s. p. 851-861
  • Konferensbidrag (refereegranskat)abstract
    • How are new long-term energy targets for buildings managed in public construction client organisations? This paper presents an empirical account of the actors, their roles and contributions to the meaning making process regarding an energy target for public buildings and the development of an energy strategy. With this account, we wish to initiate a discussion on what actors and practices that are need in construction sector when contextualising and implementing long-term energy targets in practice. The paper is based on a longitudinal study in a public construction client organisation in Sweden, where for example in-depth interviews and observations of meetings has been used for data gathering.

  • A scientific standpoint in society questions
  • 2004
  • Ingår i: Fysikaktuellt. ; :1, s. 14-15
  • Tidskriftsartikel (refereegranskat)abstract
    • Vetenskapliga frågor med samhällsrelevans är ofta mycket komplexa. En del är känt, en del är okänt. En förståelse för problemen kräver ofta djupa specialkunskaper inom många olika ämnen och ett samarbete mellan experter inom olika områden är därför väsentligt. Data kan ofta vara ofullständiga och kontrollerade experiment kan av olika skäl vara olämpliga eller omöjliga. Hur dessa frågor skall kunna presenteras på ett rimligt korrekt och begripligt sätt för allmänheten är naturligtvis inte en strikt naturvetenskaplig fråga, men naturvetare som skall arbeta med komplexa frågor behöver förståelse även för dessa aspekter.

  • Conceptualizing Knowledge Intensive Entrepreneurship: Definition and Model
  • 2015
  • Ingår i: Dynamics of knowledge intensive entrepreneurship business strategy & public policy edited by Franco Malerba, Yannis Caloghirou, Maureen McKelvey, Slavo Radosevic.. - 9781138025288 ; , s. 19-47
  • Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
    • Knowledge intensive entrepreneurship (KIE) helps renew the economy, giving rise to new industries but also to entrepreneurial-driven renewal within existing industries. This chapter proposes a conceptualize KIE as a broad concept, including a definition and a model. This chapter examines specific aspects of knowledge intensive entrepreneurship, presenting a conceptualization. The chapter also discusses framework how to operationalize the dimensions of the definition through various research strategies, and explains how the AEGIS project did so. Knowledge-intensive entrepreneurship is considered a key socio-economic phenomenon that drives innovation, and economic growth, and is at the base of the competitiveness of countries.

  • Home setting after stroke, facilitators and barriers: a systematic literature review
  • 2018
  • Ingår i: Health and Social Care in the Community. - : Hindawi Limited. - 1365-2524 .- 0966-0410. ; 26:4, s. e451-e459
  • Forskningsöversikt (refereegranskat)abstract
    • This paper seeks to improve the understanding of the interaction between patients with stroke and the physical environment in their home settings. Stroke care is increasingly performed in the patient’s home. Therefore, a systematic review was conducted to identify the existing knowledge about facilitators and barriers in the physical environment of home settings for the stroke rehabilitation process. Based upon Arksey and O’Malley’s framework, a Boolean search strategy was performed in the databases; CINAHL, Medline, Web of Science and Scopus. Fifteen articles were retained from the literature search conducted between August and November 2016, and two researchers independently assessed their quality based on the Swedish Council on Health Technology Assessment guidelines. The results suggest that despite the healthcare system’s ongoing shift towards home-based rehabilitation, the role played by the physical environment of home settings is still considered a side finding. Moreover, the research appears to focus mainly on how this environment supports mobility and activities of daily living, whereas information regarding the psychosocial and emotional processes that mediate the interaction between stroke survivors and their home setting are missing. A lack of information was also found with regard to the influence of different geographic locations on the stroke rehabilitation process. Future investigations are therefore needed to advance the understanding of the role played by the physical environment of home settings in supporting stroke recovery.

  • Radio spectrum regulation as a matter of international affairs: discussing the effectiveness of the European Union at World Radiocommunication Conferences
  • 2018
  • Ingår i: Digital Policy, Regulation and Governance. - 2398-5038. ; 20:5, s. 373-398
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: This paper aims to discuss the effectiveness of the European Union (EU) at World Radiocommunication Conferences (WRCs) by comparing EU objectives prior to and outcomes of recent WRCs. Design/methodology/approach: A thematic analysis of qualitative data extracted from documents is conducted. The effectiveness of the EU is discussed by using the concepts of agenda-setting and coalition-building, borrowed from international relations literature. Findings: A clear conclusion on EU effectiveness could not be drawn based on the degree of match between EU objectives and WRC outcomes. Other factors need to be included in the analysis, such as relevance of the EU’s participation at WRCs to the EU member states and availability and allocation of EU resources to the various stages of the WRC process. Research limitations/implications: Further research is encouraged to investigate the role of the EU at WRCs. In particular, interviews with experts involved in the WRC process may help gather relevant information on EU relevance and EU resource availability and allocation. Originality/value: This paper contributes to existing research on international radio spectrum regulation by drawing attention to the role of the EU as an international actor.

  • Closing the food loops: Guidelines and criteria for improving nutrient management
  • 2015
  • Ingår i: Sustainability: Science, Practice, and Policy. - : Informa UK Limited. - 1548-7733. ; 11:2, s. 33-43
  • Tidskriftsartikel (refereegranskat)abstract
    • As global consumption expands, the world is increasingly facing threats to resource availability and food security. To meet future food demands, agricultural resource efficiency needs to be optimized for both water and nutrients. Policy makers should start to radically rethink nutrient management across the entire food chain. Closing the food loop by recycling nutrients in food waste and excreta is an important way of limiting the use of mineral nutrients, as well as improving national and global food security. This article presents a framework for sustainable nutrient management and discusses the responsibility of four key stakeholder groups—agriculture, the food industry, consumers, and waste management—for achieving an effective food loop. In particular, we suggest a number of criteria, policy actions, and supporting strategies based on a cross-sectoral application of the waste hierarchy.
