Abstract Goalkeepers hold a key position for success in team sports competitions. They perform in dynamical contexts and are highly submitted to time pressure. The purpose of this naturalistic case study, therefore, was to explore how a handball expert goalkeeper deals with the uncertainty of the competition settings to make successful decisions. An individual self-confrontation interview was held with a goalkeeper while he watched duels with potential throwers in an official competition. A mixed method was used combining the first-person and third-person point of view. Verbal data were supplemented by observational data (distance measures between the goalkeeper and the potential thrower) in 83 short accounts of decision-making situations. Qualitative analysis resulted in 419 units of salient features, in three types of processes related to the Recognition-Primed Decision model, and in four micro-decisions. Non-parametrical statistical analysis indicated that there was a significant effect of distances between the potential thrower and the goalkeeper, on the micro-decision categories, but not on the recognition processes. These results provide insights into cognitive contents and processes an expert goalkeeper can use under uncertainty and time pressure. The mixed method furnishes a meaningful description and a subsequent understanding of expert performances in sport.

Purpose – The purpose of this technical viewpoint is to provide a commentary of how we went about using logistics prototyping as a method to engage citizens, science fiction (SF) writers and small- to medium- sized enterprises (SME’s). Six urban logistic prototypes built on the themes of future cities, community resilience and urban supply chain management (SCM) are summarized, together with details of the data collection procedure and the methodological challenges encountered. Our investigation aimed to explore the potential of logistics prototyping to develop “user-driven” and “SME” approaches to future city design and urban supply chain decision-making. Design/methodology/approach – This Boston field experiment was a case study investigation conducted between May and August 2013. Qualitative data was collected using a “mixed-method” approach combining together focus groups (MIT faculty), scenarios, prototyping workshops, interviews and document analysis. These story-creators could use the prototype method as a way of testing their hypotheses, theories and constrained speculations with regard to specified future city and urban supply chain scenarios. Findings – This viewpoint suggests that the prototyping method allows for unique individual perspectives on future city planning and urban supply chain design. This work also attempts to demonstrate that prototyping can create sufficiently cogent environments for future city and urban SCM theories to be both detected and analysed therein. Although this is an experimental field of the SCM theory building, more conventional theories could also be “tested” in the same manner. Research limitations/implications – By embedding logistics prototyping within a mixed method approach, we might be criticized as constraining its capability to map out the future – that its potential to be flexible and imaginative are held back by the equal weighting given to the more conventional component. In basing our case study within one city then this might be seen as limiting the complexity of the empirical context – however, the situation within different cities is inherently complex. Case studies also attract criticism on the grounds of not being representative; in this situation, they might be criticized as imperfect indicators of what transpires in other situations. However, this technical viewpoint suggests that in spite of its limitations, prototyping facilitates an imaginative and creative approach to theory generation and concept building. Practical implications – The methodology allows everyday citizens and SME’s to develop user-driven foresight and planning scenarios with city strategists’ and urban logistic designers. It facilitates much broader stakeholder involvement in city and urban supply chain policymaking, than current “quantitative” approaches. Social implications – Logistics fiction prototyping provides a democratic approach to future city planning and urban supply chain design. It involves collectively imagining socio-technical futures and second-order sociological effects through the writing of SF narratives or building “design fictions”. Originality/value – Decision-making in future cities and urban SCM is often a notable challenge, balancing the varying needs and claims of multiple stakeholders, while negotiating an acceptable trade-off between their competing claims. Engagement with stakeholders and active encouragement of stakeholder participation in the supply chain aspects of future cities is increasingly a feature of twenty-first century social decision-making. This viewpoint suggests that the prototyping method allows for unique individual perspectives on future city planning and urban supply chain design. This work also attempts to demonstrate that prototyping can create sufficiently cogent environments for future city and the urban SCM theories to be both detected and analysed therein. Although this is an experimental field of SCM theory building, more conventional theories could also be “tested” in the same manner.

In a real-life scenario, it is undoable and unmanageable to solve a decision-making problem with the single stand-alone decision-aid method, expert assessment methodology or deterministic approaches. Such problems are often based on the suggestions or feedback of several experts. Usually, the feedback of these experts are heterogeneous imperfect information collected from various more or less reliable sources. In this paper, we introduce the concept of multi-sets over type-2 fuzzy sets. We have tried to propose an extension of type-1 multi-fuzzy sets into a type-2 multi-fuzzy set (T2MFS). After defining T2MFS, we discuss the algebraic properties of these sets including set-theoretic operations such as complement, union, intersection, and others with examples. Subsequently, we define two distance measures over these sets and illustrate a decision-making problem which uses the idea of type-2 multi-fuzzy sets. Furthermore, an application of a medical diagnosis system based on multi-criteria decision making of T2MFS is illustrated with a real-life case study.

Intuition is defined as a form of knowledge which materialises as awareness of thoughts, feelings and physical sensations. It is a key to a deeper understanding and meaningfulness. Intuition, used as a psychological function, supports the transmission and integration of perceptions from unconscious and conscious realms. This study uses a psychobiographical single case study approach to explore intuition across the life span of Paulo Coelho. Methodologically, the study is based on a single case study, using the methodological frame of Dilthey's modern hermeneutics. The author, Paulo Coelho, was chosen as a subject of research, based on the content analysis of first- and third-person perspective documents. Findings show that Paulo Coelho, as one of the most famous and most read contemporary authors in the world, uses his intuitions as a deeper guidance in life, for decision-making and self-development. Intuitive decision-making is described throughout his life and by referring to selected creative works.

In a previous paper the new EBSYQ (Evolutionary Based SYstem for Qualification and Evaluation of Group Achievements) system has been proposed for teachers and juries, helping them in making accurate and objective ranking. The analysis of the behaviour of the special characteristic sigmoid functions of the groups gives the possibility to discover some interesting points of view for qualifying the achievement and the standard of the groups (subgroups of talented and under- motivated students, spectrum of the group, eigenvalues, Lorentz function). This paper shows a case study of an international project of student groups competition in the field of product design, with Finnish and Hungarian students. Comparison of the decision process of the jury without using the EBSYQ system and with the application of the system shows the efficiency of the qualification system in realizing a well-founded and careful ranking of the groups, even in case of very close competition. Each point of view of the decision-making system is evaluated by numbers, which can increase the objectivity and accuracy of the decision.

Decision-making for maintenance of engineering assets is a common challenge in the process industry due to ongoing degradation. With an increasing company-size, this problem becomes more complex from an operational and computational point of view. This paper introduces a case study to the academic community that represents the problem of optimal decision-making in the context of large asset fleets. The case study poses a large fleet of offshore compressors for gas production with a specific network structure. Two exemplary discrete-time mixed integer linear programming models following the Resource Task Network framework are presented. They address asset deterioration due to effects such as fouling by suggesting specific maintenance actions as a set of different countermeasures. Novel enumerator formulations are a computationally efficient and extendable way to model the various degradation types. Results show the benefit of optimal maintenance in the application to asset fleets. The decision-support that is delivered by the scheduling and planning approach helps to determine which maintenance type should be conducted and at what time. The paper demonstrates the benefits of optimal (long-term) schedules for maintenance, but indicate at the same time the need for efficient algorithms in the context of large asset fleets, in contrast to common industrial case studies that are rather small-scale.

Vietnamese government is officially applying standards of multidimensional poverty as a basis for poverty assessment in the period 2016-2010, overcoming limitations of income poverty’s assessing methods. However, to the authors’ point of view, its selected indicators have not yet reflected the comprehensive aspects of life, while multidimensional poverty assessment (driven from OPHI) based on sustainable livelihood framework (of DFID) is considered as a better method. This research is conducted in Hang Kia and Pa Co, the mountainous communes of Mai Chau district, Hoa Binh province, by using the later methods. Total 13 indicators under 5 livelihood sources were selected. As the results, the rates of multidimensional poverty in these two communes were shown by the insufficiency in each indicator, by communes and by kinds of poverty households. This result can be used for better decision- making on poverty reduction

BACKGROUND Games are present in society, representing the most diverse activities. A brief conceptual approach to gaming is necessary to the broadening of its understanding within the social and educational context. With the use of digital games in education, known as serious game, the education of dentistry students and dentists may include new complementary approaches. OBJECTIVE To report the project and the development criteria of a serious game in clinical decision-making cases, in the sphere of Dentistry, as a complementary teaching tool. METHODS Case study of the development of the content and narrative of a serious game decision-making process in the dental clinic. In Dental Case, players assume the role of a dentist in consultation, whose mission goes through the stages of Medical history, clinical examination, complementary examination, diagnosis, and treatment. The situations presented in the game were designed to be similar to situations of decision making in the dental clinic in the context of primary health care. The content developed was reviewed and validated by specialists, both from a technical and pedagogical point of view, to be later inserted into the game software by the IT team. RESULTS We developed Dental Case, a serious game with a set of clinical cases for professionals and Dentistry students to support teaching in decision making at different stages of the clinic. The game is available for free on the web and in the Play Store and Apple Store mobile app stores. CONCLUSIONS New complementary pedagogical approaches in the field of Dentistry are necessary. The resources provided by Dental Case are presented as a potential tool in educational technologies aimed at Dentistry and may contribute to expanding the scale and scope of educational activities. Subsequent to this, learning effectiveness tests will be carried out.

In this chapter, the development of the Educator Ethics and Conduct Toolkit (EECT) will be examined. The EECT was created as part of a comprehensive initiative for developing Professional Ethics for preservice and new teachers across the state. Rather than examine educator ethics from a philosophical point of view, the EECT is a practical, scenario-based curriculum which helps beginning teachers examine their fiduciary responsibilities and analyze ethical decision-making in authentic contexts. Utilizing a case study approach, the chapter examines the overall instructional design, development and implementation of the curricular materials.

Decision making under uncertainty is a crucial issue and most demanding area of research now a days. Intuitionistic hesitant fuzzy set plays important role in dealing with the circumstances in which decision makers judge an alternative with a collection membership grades and a collection of non-membership grades. This paper contributes a novel and advanced distance measure between Intuitionistic Hesitant fuzzy sets (IHFSs). A comparative analysis of the present distance measure with existing measures is performed first. Afterwards, a case study is carried in multi-criteria decision making problem to exhibit the applicability and rationality of the proposed distance measure. The advantage of the proposed distance measure over the existing distance measures is that in case of deficit number of elements in IHFs, a decision maker can evaluate distance measure without adding extra elements to make them equivalent and furthermore, it works in successfully in all the situations.

Introduction. The cognitive functions usable in the sports performance are for example an ability to anticipate, perception and speed of movement reactions, decision-making ability or attention. These abilities or functions apply differently to different sports. It means that open skill sports such as team sports, require the coordination of complex bodily movements and adaptation to continually changing task demands.The aim of this study is to identify differences in the level of female's cognitive functions regarding the chosenopen skill sportsand closed skill sport disciplines. Material and Methods. The research group consisted of 84 women aged 22.70±1.71 years. Women were divided into three groups in terms of sport discipline into: female engaged in closed skill sport disciplines (n=26), in open skill sport disciplines (n=19) and not engaged in any sport activity (n=39). We used standardized S-test to determine the level of cognitive functions. It is a test of spatial orientation and concentration of attention with accentuated demands on the pace of activity. Results. The results have shown that female engaged in open skill sport disciplines have shown higher level of cognitive functions than female engaged in closed skill sport disciplines (p=0.04) and also as nonathletes (p=0.02). There was no difference in cognitive function between female engaged in closed skill sport disciplines and nonathletes. Conclusions. Our results confirm the theory of different involvement of cognitive functions from the point of view of different types of sport disciplines.
