Collaborative Decision

Purpose – The purpose of this paper is to test the influence of collaborative and consultative decision rules on groups’ sensitivity to framing effect (FE) and escalation of commitment (EOC). Design/methodology/approach – In an experimental study (using a sample of 233 professionals with project management experience), the authors test the effects of collaborative and consultative decision rules on groups’ sensitivity to EOC and FE. The authors use four group decision-making tasks to evaluate decision consistency across gain/loss framed decision situations and six decision tasks to evaluate EOC for money as well as time as resources previously invested in the initial decisions. Findings – The results show that the collaborative decision rule increases sensitivity to EOC when financial resources are involved and decreases sensitivity to EOC when time is of essence. Moreover, the authors show that the collaborative decision rule decreases sensitivity to FE in group decision making. Research limitations/implications – The results have important implications for group rationality as an emergent group level competence by extending the insights concerning the impact of decision rules on emergent group level cognitive competencies. Due to the experimental nature of the design, the authors can probe the causal relations between the investigated variables, yet the authors cannot generalize the results to other settings. Practical implications – Managers can use the insights of this study in order to optimize the functioning of decision-making groups and to reduce their sensitivity to FEs and EOC. Originality/value – The study extends the research on group rationality and it is one of the few experimental attempts used to understand the role of decision rules on emergent group level rationality.

Post Disaster

Purpose The purpose of this paper is to reveal the importance of the order of establishment of temporary logistics hubs (TLHs) when resources (mobile storage units used as TLHs) are limited and to present the development and implementation of a methodology that determines the order of establishment of TLHs to support post-disaster decision making. Design/methodology/approach It employed a decision support system that considers multiple decision makers and subjective attributes, while also addressing the impreciseness inherent in post-disaster decision making for ordering the establishment of TLHs. To do so, an optimization model was combined with a fuzzy multi-attribute group decision making approach. A numerical illustration was performed using data from the April 2015 Nepal Earthquake. Findings The results showed the location and order of establishment of TLHs, and demonstrated the impact of decision makers’ opinions on the overall ordering. Research limitations/implications The study does not discuss the uncertain nature of the location problem and the potential need for relocation of TLHs. Practical implications This methodology offers managerial insights for post-disaster decision making when resources are limited and their effective utilization is vital. The results highlight the importance of considering the opinions of multiple actors/decision makers to enable coordination and avoid complication between the growing numbers of humanitarian responders during disaster response. Originality/value This study introduces the concept of the order of establishment of TLHs and demonstrates its importance when resources are limited. It develops and implements a methodology determining the order of establishment of TLHs to support post-disaster decision making.

The Impact

BackgroundFamily group decision-making (FGDM) is a structured decision-making process, aiming to shift the balance of power from professional towards the person in need and their family. It differentiates from other family-centred meetings by the presence of three key elements: (1) plan with actions/goals, (2) family driven, (3) three phases of meetings gradually increasing empowerment. FGDM studies are increasing in different settings in adult healthcare/welfare, although effectiveness is unknown at this date.Objectives(1) to systematically review the presence of the three FGDM key elements in family-centred interventions in adult care and welfare, (2) to evaluate the effectiveness of FGDM interventions.DesignSystematic review.Data sources and eligibility criteriaA total of 14 relevant electronic databases and 1 academic search machine were searched until February 2018. First, family-centred studies were selected with controlled trial designs in adult healthcare/welfare. Second, interventions were categorised as FGDM if all three key elements were present.Data extraction and synthesisStudies were examined concerning their (1) characteristics (2) quality/level of evidence (3) presence of FGDM key elements and (4) results.ResultsSix articles from three studies on family-centred interventions were selected from a total of 1680 articles. All were of low quality. One study (two articles) met all criteria for an FGDM intervention, describing the efficacy of family group conferences among social welfare recipients on mental health outcomes. Although the intervention group showed significantly better outcomes after 16–23 weeks; no differences were seen at the 1-year follow-up.ConclusionsControlled studies of both family-centred interventions and FGDM are still low in quantity and quality. No conclusions on FGDM effectiveness can be drawn. Further high-quality intervention studies are required to evaluate the impact of FGDM on adults in need, including their families; as well as evaluation research detecting possible barriers and facilitators influencing FGDM implementation.PROSPERO registration numberCRD42017077585.

Purpose – The purpose of this paper is to select the best scaling coefficient during the quantitative-qualitative conversion. Design/methodology/approach – Cloud model can describe the qualitative concept of randomness and fuzziness, achieve uncertain transition between qualitative and quantitative in the field of multi-criteria group decision and has been receiving widespread attention. This paper discusses scale conversion issues of the cloud model when evaluating qualitative information. In order to improve the accuracy of the evaluation on multi-attribute decision problems based on uncertainty of natural linguistic information, this paper proposes a method of self-testing cloud model based on a composite scale (with the exponential scale and the scale as a basis). Findings – Through experimental verification results show that under composite scale, the best suitable selection of can effectively improve the accuracy and reliability of decision results. Originality/value – This research presents a new approach to determine the suitable value for coefficient based on uncertain knowledge of natural multi-criteria group decision making, and gives concrete steps and examples. This method has positive significance to improve the quality of qualitative and quantitative conversion based on cloud model.
