Research into group decision-making suggests that, dependent on the information distributed prior to a group discussion, the decision and discussion content can be predicted. While the impact to group decision-making has been studied, its impact on collaborative activities such as design review has not been well investigated. A full factorial design of experiments (3×3, DOE) is conducted to investigate the influence of group cohesion and the awareness of the presence of unshared information among group members on design review effectiveness. The results suggest that awareness may have an effect on locating design issues by representation, functional group domain, and the total amount of design issues located.

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.

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.

Leaderless group decision-making denotes the idea that political decisions from a non-hierarchical discussion structure can be more legitimate and effective than those from a hierarchical structure. Since the latter half of the 20th century, such decision-making has been practiced widely in community groups, non-governmental organizations (NGOs), “deliberation” forums, as well as in the business and management settings. While one may argue its origins go back to Athenian direct democracy, it was the zeal of the 1960s participatory democracy movement in the United States that produced the more sophisticated principles, philosophies, and mechanics of leaderless group decision-making. The progressive social movement activists at that time considered non-hierarchical groups as ethically appropriate to their causes. Since then, this tradition of leaderless group decision-making processes has been adopted in many grassroots social movements. Debates and controversies abound concerning leaderless group decision-making. It has been a normative imperative for many social activists to adopt decision-making in a leaderless manner. Research to date, however, has produced no conclusive evidence that leaderless group discussion results in better or more effective decisions. Proponents argue that members of a leaderless group would develop greater capacities for self-governance because in such a setting they can take more personal and egalitarian initiatives to organize activities of the group. This, in turn, would lead to better group dynamics and discussion, and, eventually, better decisions. Critics suggest that leaderless groups are slow and inflexible in decision-making and that the supposedly leaderless groups usually end up with leaders because of the social dynamics and human nature present in group interactions. Regardless of its potential benefits and problems, the ideals of deliberative and participatory democracy are strongly propelling this egalitarian, discourse-based form of group decision-making. Researchers will gain a great deal of insight from literature in deliberation concerning the functions, problems, and future directions of leaderless groups. In addition, there is a need to study leaderless groups in a more multi-faceted way, as research to date has been dominated by psychology-based quantitative assessment of groups. Qualitative and ethnographic approaches will be helpful to further assess the dynamics of leaderless group decision-making.

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.

Much recent research indicates that discussion predictably affects responses to choice-dilemma items. In the present experiment, 12 choice-dilemma items were discussed to consensus by 40 female groups of varying size (2, 3, 5, or 7 members). Group size did not significantly affect shift scores. Over all groups, the mean of initial risk taking on an item was an excellent predictor of the mean amount of shift that item elicited ( r = –.89), a finding consistent with certain models of group decision making as well as with the idea that discussion arguments enhance dominant values. Further analyses of the present and past research indicated that the group decision making models could not account for the observed shifts.

Neutrosophic cubic set is the hybridization of the concept of neutrosophic set and interval neutrosophic set. Neutrosophic cubic set has the capacity to express the hybrid information of both the interval neutrosophic set and the single valued neutrosophic set simultaneously. As newly defined, little research on the operations and applications of neutrosophic cubic sets appear in the current literature. In the present paper we propose the score, accuracy functions for neutrosophic cubic sets and prove their basic properties. We firstly develop TODIM method to solve multi attribute group decision making in neutrosophic cubic set environment, which we call NC-TODIM. Also, we solve a MAGDM problem using the proposed NC-TODIM method to show the applicability and effectiveness of the developed method. We also conduct sensitivity analysis to show the impact of ranking order of the alternatives for different values of attenuation factor of losses for multi-attribute group decision making problem.
