Eight participants reviewed a multimedia presentation regarding the hypoxic zone phenomenon in a role-play as a legislator's aide. They rated the phenomenon's importance to the United States and indicated what portion of the legislator's budget to devote to research of it. After viewing a segment of the presentation, participants indicated their distance to a decision and confidence that would be their final decision. Interviews after each segment revealed two decision strategies: slow movement toward a decision, or abrupt decision-making after approximately half the presentation. Decision style was correlated with decision confidence. These two groups differed in their trade-offs of willingness to spend time in information search and need for more information. Slow decision makers were less confident about their final decision; acquisition of information was more critical than time spent on the information search. Abrupt decision-makers were more confident of their final decision; minimizing time spent in information search was more critical than information acquisition.

Decision Board

Systematic study of the decision-making process at each critical stage of the criminal justice system has been limited. Specifically, little attention has been given to the decision-making of police on whether or not to process juveniles into and through the system. Even more remarkable is the lack of research on the types of information police use to arrive at their decisions. One device available for studying information handling in decision-making is the information or decision board developed by Leslie Wilkins. The technique simulates, as closely as possible, the real-life use of information and allows for rigorous experi mental conditions. By use of this technique, the decision- making of twenty-four policemen was studied—specifically, the amount and types of information each used to make a decision about a juvenile charged with drunk and disorderly conduct. The results show that police use more information to make a decision than is popularly believed. On the average, five pieces of information were selected before a decision was reached. The data also indicate that younger officers (less than five years on the job) tend to use nearly twice as much information as their more experienced counterparts (five or more years on the job) and that these two groups of officers do not always reach the same final decisions. Twenty-three of the twenty-four officers selected offense first, but the most critical topic for reaching a final decision was attitude of offender. Eighteen of the twenty-four officers made a decision when this piece of information was selected. Surprising ly, the piece of information race had little significance in the decision-making process. This study shows that the information board can be used effectively to examine the decision-making of police in their processing of juveniles. The data suggest that future studies may be able to identify types of decision-makers among police by examining their information-search profiles.

This article expands the evidence about integrative thinking by analyzing two case studies that applied the collaborative decision-making method of deliberative democracy which encourages representative, deliberative and influential public participation. The four-year case studies took place in Western Australia, (1) in the capital city Perth and surrounds, and (2) in the city-region of Greater Geraldton. Both aimed at resolving complex and wicked urban sustainability challenges as they arose. The analysis suggests that a new way of thinking, namely integrative thinking, emerged during the deliberations to produce operative outcomes for decision-makers. Building on theory and research demonstrating that deliberative designs lead to improved reasoning about complex issues, the two case studies show that through discourse based on deliberative norms, participants developed different mindsets, remaining open-minded, intuitive and representative of ordinary people’s basic common sense. This spontaneous appearance of integrative thinking enabled sound decision-making about complex and wicked sustainability-related urban issues. In both case studies, the participants exhibited all characteristics of integrative thinking to produce outcomes for decision-makers: salience—grasping the problems’ multiple aspects; causality—identifying multiple sources of impacts; sequencing—keeping the whole in view while focusing on specific aspects; and resolution—discovering novel ways that avoided bad choice trade-offs.

AbstractStudent dropout can be conceptualized as a decision-making process, consisting of different phases. Based on previous literature on student dropout, decision-making, and action-phases, we proposed that the process of developing dropout intentions includes the following phases: non-fit perception, thoughts of quitting/changing, deliberation, information search, and a final decision. In the present cross-sectional study, we empirically investigated if the assumed phases can be distinguished from each other, if the phases follow the presumed order, and whether each phase is associated with certain characteristics. Furthermore, we considered a strict separation between quitting studies completely and changing a major. For this purpose, we analyzed data of N = 1005 students (average age of 23.0 years; 53% female; 47% male) from a German University. By using confirmatory factor analyses, we found the supposed factor structure for the different phases concerning both kinds of dropout, quitting studies, and changing majors. In each process, structural equation modelling indicated positive relations between adjoining phases. The factor values correlated to a substantial amount with an assortment of variables associated with student dropout. On a theoretical level, the conception of different phases of student dropout helps to get a better understanding of regulatory processes in the context of student dropout.

Theory Of Fuzzy Sets

Summary The theory of fuzzy sets allows to analyze insufficiently precise, accurate, complete phenomena which can not be modeled by the theory of probability or interval mathematics. We define fuzzy sets as sets where the boundary of the set is unclear and depends on subjective estimation or individual preference. In addition to the standard interpretation scale, described above, a set of numbers to each qualitative attribute must be assigned. In addition to the standard interpretation scale a set of numbers to each qualitative attribute must be assigned. First of all, it is necessary to determine the procedure for determining fuzzy numbers describing the attributes. One of the imperfections of the fuzzy sets is subjectivism when defining the boundaries of fuzzy sets and functions of belonging, which can significantly influence the final decision. The decision maker’s subjectivity is also present in the determination of weighted coefficients. However, in case of giving weight, fixed values are necessary. Some decisions require multidisciplinary knowledge, so the decision-making process includes more group decision-makers, who independently give their grades.

This chapter uses intuitionistic fuzzy VIKOR (IFVIKOR) for the application of ERP software selection. First, priority values of criteria in ERP software selection problem have been determined by using the judgments of the experts. IFWA operator is utilized to integrate the judgments of the experts about the weights of criteria. Then, the result of the IFVIKOR can be employed to define the most appropriate ERP alternative in uncertain environment. Intuitionistic fuzzy numbers are presented in all phases in order to overcome any vagueness in the decision-making process. The final decision depends on the degree of importance of each decision so that wrong degree of importance causes the mistaken result. The researchers generally determine the degrees of importance of each decision makers according to special characteristics of each decision maker as subjectivity. In order to overcome this subjectivity in this chapter, the judgments of decision makers are degraded to unique decision by using the importance degree of each expert. There is no study about ERP software selection using IFVIKOR.

The Individual

The current study aims to investigate how the presence of social norms defines belief formation on future changes in social identity (i.e., diachronic identity), and how those beliefs affect individual decisions under uncertainty. The paper proposes a theoretical model in which individuals have preferences over their own attributes and over specific information structures. The individual preferences are motivated by the presence of social norms. The norms, while establishing the socially acceptable attributes of an individual identity, also drive individuals’ preferences for information acquisition or avoidance. The model incorporates social norms as empirical expectations and provides a prior dependent theory that allows for prior-dependent information attitudes. Firstly, the model implies that decisions are mitigated by socially grounded behavioral and cognitive biases; and secondly, that it can create an incentive to avoid information, even when the latter is useful, free, and independent of strategic considerations. These biases bring out individual trade-offs between the accuracy of decision making and self-image motivated by social conformity. The two behavioral motivations are represented through a game of an intra-personal model of choice under uncertainty in which self-deception and memory manipulation mechanisms are used to overcome the individuals’ internal trade-off.

Decision making in the domain of risk has traditionally been studied by examining gambling behavior. The control of outcome probabilities obtained in these paradigms masks much of the subjective nature of everyday risk decision choices, such as product selection and information search patterns. A study was undertaken to examine decision making processes in Risky and NonRisky consumer product decision tasks. Subjects completed two Information Display Board (IDB) decision tasks, one selecting a Risky consumer product (oral contraceptive) and one selecting a NonRisky consumer product (toothpaste). The results supported the hypotheses that consumers view the decisions to purchase risky and non-risky products differently and use different patterns of information acquisition in making decisions in the selection of these products. Few anticipated differences were found between Experienced and NonExperienced users of oral contraceptives in information acquisition. Implications for health care professionals providing oral contraceptive information to patients are discussed.

Abstract This study examines the initial impact of a broadly participatory planning process in the Czech Republic during 2016–2017, aimed at both reducing inpatient care and expanding community mental health systems, on policy and programmatic decision making. A central focus of the study involves the trade-offs between and efforts to integrate shared decision making with evidence-based planning methods within the context of a national psychiatric reform strategy, particularly one involving a former Soviet bloc state. Given the uniqueness of the Czech experience, an exploratory case study methodology is used, one involving ten interviews with key informants and examination of a wide variety of documents. Results include the development of broad new decision and oversight structures, and the initial implementation of community mental health services. The nation faces some of the same trade-offs found elsewhere, such as in the United States, between an inclusive participatory process, and one that systematically incorporates empirical rational and evidence and best practices within bounded parameters. Implications for new psychiatric deinstitutionalization initiatives are identified, including development of a national mental health authority, a professional workforce, new funding strategies, multi-level service coordination, mechanisms to assure transparency, among others.
