Decision-Making with Belief Functions: a Review

Approaches to decision-making under uncertainty in the belief function framework are reviewed. Most methods are shown to blend criteria for decision under ignorance with the maximum expected utility principle of Bayesian decision theory. A distinction is made between methods that construct a complete preference relation among acts, and those that allow incomparability of some acts due to lack of information. Methods developed in the imprecise probability framework are applicable in the Dempster-Shafer context and are also reviewed. Shafer's constructive decision theory, which substitutes the notion of goal for that of utility, is described and contrasted with other approaches. The paper ends by pointing out the need to carry out deeper investigation of fundamental issues related to decision-making with belief functions and to assess the descriptive, normative and prescriptive values of the different approaches

Challenging partnerships: Sustaining women's collaborative relationships in changing business and political environments

Senior managers, practitioners and users of public, community and voluntary sector services are currently struggling to develop effective partnership workingwithin increasingly challenging political and organisational environments. Women's organisations face specific challenges to represent their sector and issueseffectively within these partnershipsThis research report explores and theorizes the specific challenges experienced by women who came together from different countries, organisations and sectors tocreate new methods for mainstreaming women's equality and for sustaining women in leadership roles.It offers:· An approach for supporting partnerships and collaborations between women and between women and men across organisations and sectors;· Methods for facilitating collaboration and learning within and across organisational boundaries.The doctoral research was conducted through action inquiry and based on consultancy practice, 1997-2001. Through the research practical methods were developed for facilitating learning between diverse individuals from different countries, organisations and sectors, and for sustaining them as they implemented new practice within their organisations. This report introduces a conceptual framework for effective working within partnerships and across organisational boundaries and describes the methods and associated skills that were developed. It will be of interest to action researchers and practitioners in women's organisations and within the wider voluntary sector. It will also be of use to women and men who are seeking more effective ways of working to promote gender equality and diversity in public services, in the context of multi organisational, cross sectoral or transnational partnerships

Reconfiguring what network? (Road) network synchronization in Dutch traffic management

Current sustainability challenges are increasingly acknowledged to reveal systemic flaws in societal systems such as energy, mobility and agriculture. Adequate solutions then require system innovations and societal transitions. The quest for system innovation is notoriously hard, however: In a polycentric society systemic problems tend to be elusive, and solution strategies are contested. So whereas the quest for system innovation is typically backed by substantive analyses of system pathologies, polycentric perspectives emphasize that the intrinsic properties of an innovation attempt are hardly decisive. Innovation attempts need to be relevant to the targeted actors in the first place

Job (In)Security and Workers’ Training Decisions: A Framing Approach

Context: In this study, we attempt to contribute to the scarce evidence about the relationship between perceived labour market insecurity and worker training investments. Drawing on existing research into framing in decision-making, we investigate whether framing the labour market as insecure increases the willingness of workers to invest in training. We also investigate whether this effect is larger when training contract terms are favourable, such as when training is done mostly in an employer’s time, or when no payback clause is included.Approach: Data are gathered through a vignette-study under a sample of senior Dutch students, with experimental manipulation of frames. Respondents are given a questionnaire in which they are asked to imagine themselves working for a fictitious firm (but presented to them as real). The security/insecurity frames are elicited by randomly stressing either the positive or negative side of a series of events related to the labour market position of people working in this firm. Respondents are then asked to respond to five vignettes, each of these a randomly generated combination of training contract terms. For each vignette, respondents are asked to state whether or not they would be willing to go along with the specified training program under the conditions outlined in that vignette. Data are analysed with multilevel logistic regression. Findings: The willingness to train is not invariably greater under an insecurity frame. Instead, we find a crucial interaction: the willingness to train is greater under an insecurity frame when training-contract terms are favourable (e.g when no payback clause is included), but smaller when training-contract terms are unfavourable. Since the positive and negative effects are approximately equal in size, in a balanced design such as ours they cancel each other out, resulting in a close to zero overall effect for the frame variable.Conclusion: Our results suggest that, when workers are aware of the insecurity in their situation, this only makes them more willing to follow training when the risk of losing their investment is low.

Sexual health help-seeking behavior among migrants from sub-Saharan Africa and South East Asia living in high income countries: A systematic review

The number of migrants has increased globally. This phenomenon has contributed to increasing health problems amongst migrants in high-income countries, including vulnerability for HIV acquisition and other sexual health issues. Adaptation processes in destination countries can present difficulties for migrants to seek help from and gain access to health services. This study examined migrants’ from sub-Saharan Africa (SSA) and South East Asia (SEA) sexual health help-seeking behavior in high-income countries with universal health coverage. The systematic review followed PRISMA guidelines and was registered with PROSPERO. Several databases were searched from 2000 to 2017. Of 2824 studies, 15 met the inclusion criteria. These consisted of 12 qualitative and three quantitative studies conducted in Australia, Spain, the United Kingdom, Belgium, Scotland, Ireland, and Sweden. Migrants experienced a range of difficulties accessing health services, specifically those related to sexual health, in high-income countries. Few studies described sources of sexual health help-seeking or facilitators to help-seeking. Barriers to access were numerous, including: stigma, direct and indirect costs, difficulty navigating health systems in destination countries and lack of cultural competency within health services. More culturally secure health services, increased health service literacy and policy support to mitigate costs, will improve health service access for migrants from SSA and SEA. Addressing the structural drivers for stigma and discrimination remains an ongoing and critical challenge
