The purpose of this study was to examine the influence of manipulating game constraints on match performance in youth field hockey. A total of 25 participants aged 10.6–14.6 years old played four different 25-min games where density (228 m2 or 158 m2 per player) and/or number of players (11 per side or 8 per side) was manipulated. Match performance was determined by using notational analysis and physical demands were determined by using GPS analyses. Manipulating the number of players led to an increase in a successful passes (+2.68 passes), skilled actions (+3.73 skilled actions) and successful actions (+3.77 successful actions) performed per player and also created a more advantageous environment to enhance decision making. Increasing the density led to a decrease in unsuccessful dribbles (−0.59 unsuccessful dribbles) made by players and an increase in high intensity running (+38 m) and sprinting (+21.2 m). The findings of this study provide an insight into the effect of manipulating task constraints in skilled junior field hockey and the findings highlight that all types of constraints influence emergent performance in their unique way and that coaches should consider these interactions to promote specific playing behaviour.

El objetivo del estudio fue analizar el efecto de manipulación de diferentes condicionantes de la tarea sobre la toma de decisiones y la eficacia de la acción de ataque en voleibol. Se planteó un diseño pre-experimental en el que participaron 22 alumnos de Educación Física con una edad comprendida entre los 12 y 13 años. La variable independiente fue un programa de intervención aplicado durante las 9 sesiones de una Unidad Didáctica, la cual fue diseñada en base a los principios metodológicos de la pedagogía no lineal, centrándose fundamentalmente en manipular condicionantes de la tarea, tales como, espacio de juego, altura de la red y número de participantes. Las variables dependientes fueron la toma de decisiones y la eficacia en la acción de ataque. Ambas variables fueron evaluadas a partir de la observación sistemática, utilizando el “Game Performance Assesment Instrument” (GPAI) (Oslin, Mitchell, & Griffin, 1998) para la toma de decisiones y el “Team Sports Assesment Procedure” (TSAP) (Gréhaigne et al., 1997) para la eficacia de la acción de ataque. Los resultados del estudio determinaron que todos los participantes manifestaron una mejora significativa, tanto en la toma de decisiones como en la eficacia entre la medida pre-test y pos-test. Respecto a estos resultados, el profesor de Educación Física, con el propósito de hacer progresar a los alumnos en su competencia táctica, debe diseñar tareas motrices que sean representativas del juego real y cuya complejidad táctica sea adaptada al nivel de aprendizaje de los discentes.Abstract. The aim of the study was to analyze the effect of manipulating different task constraints, such as play space, net height and number of participants on decision-making and efficacy in the attack action in volleyball. A pre-experimental design, in which 22 students aged between 12 and 13 years participated, was implemented. The independent variable was an intervention program applied during the 9 sessions of a teaching unit, which was designed based on the methodological principles of nonlinear pedagogy, focusing primarily on manipulating the different task constraints referred to above. The dependent variables were the decision-making and the efficacy in the attack action. Both variables were evaluated through the systematic observation of the game action, using the Game Performance Assessment Instrument (GPAI; Oslin, Mitchell, & Griffin, 1998) for decision-making and the Team Sports Assessment Procedure (TSAP; Gréhaigne et al., 1997) for the efficacy of the attack action. The results of the study showed that all participants improved both decision making and efficacy between the pre-test and post-test measures. Regarding these results, Physical Education teachers, with the purpose of advancing students in the tactical competence, should design tasks representative of the game and with a tactical complexity adapted to the learning level of the students.

AbstractThis study tested the use of two pedagogical principles of Game-based approaches, representation and exaggeration, in the context of game performance of U10 soccer players. Twenty-one players participated in two 3 vs. 3 small-sided games. The first small-sided game was modified by representation. The second small-sided game was modified by enhancing the penetration of the defense tactical problem for invasion games. Decision-making and execution were assessed using the Game Performance Evaluation Tool. No significant differences were observed between games in the number of decision-making units related to keeping possession, nor in those related to penetrating the defense. No significant differences were observed in any execution ability (ball control, passing, dribbling and get free movements). The findings suggested that both games could provide similar degeneracy processes to the players for skill acquisition (specific and contextualized task constraints in which they could develop their game performance and the capability to achieve different outcomes in varying contexts). Probably both games had similar learner-environment dynamics leading players to develop their capabilities for adapting their behaviours to the changing performance situations. More research is necessary, from the ecological dynamics point of view, to determine how we should use small-sided games in Game-based approaches.

Abstract. Folk wisdom tells us that additional time to make a decision helps us to refrain from the first impulse to take the bird in the hand. However, the question why the time to decide plays an important role is still unanswered. Here we distinguish two explanations, one based on a bias in value accumulation that has to be overcome with time, the other based on cognitive control processes that need time to set in. In an intertemporal decision task, we use mouse tracking to study participants’ responses to options’ values and delays which were presented sequentially. We find that the information about options’ delays does indeed lead to an immediate bias that is controlled afterwards, matching the prediction of control processes needed to counter initial impulses. Hence, by using a dynamic measure, we provide insight into the processes underlying short-term oriented choices in intertemporal decision making.

Research carried out in the last few years as the example of companies belonging to the category of medium-size enterprises has shown that, for example, typical enterprises, of the total number of data processed in information of importance for its business, seriously takes into consideration and process only 10% of the observed firms. It is justifiable to ask whether these 10% of the processed and analyzed business information can have an adequate potential or motive power to direct the organization to success that is measured by competitive advantages and on a sustainable basis? Or, the question can be formulated: what happens to the rest, mostly 90% of the information that the enterprise does not transform into a form suitable for business analysis and decision-making. It is precisely the task of business intelligence to find a way to utilize all the data collected and processed in the business decision-making process. In this regard, we can conclude that Business Intelligence is, in fact, the framework title for all tools and / or applications that will enable the collection, processing, analysis, distribution to decision-making bodies in the business system in order to derivate from this information valid business decisions - as the most important and / or most important task of the manager. Of course, from an economic point of view, the best decisions are management decisions that provide a lasting competitive advantage and achieve maximum financial performance. This means that business intelligence actually allows a more complete and / or comprehensive view of the overall business performance of all its parts and subsystems. But the system functions can be measured essential and positive economic and financial performance, as well as the position in the branch of the business to which it belongs, and wider, within the national economy. (Of course, today the boundaries of the national economy have become too crowded for many companies, bearing in mind globalization and competitiveness in the light of organization of work and business function). The advantage of business intelligence as a model, if accepted at the organization level, ensures that each subsystem in the organization receives precisely the information needed to make development decisions, but also decisions regarding operational activities. So, it should be born in mind that business intelligence does not imply that information is shared on some key words, on the contrary, the goal is to look at the context of the business, or in general, and that anyone in the further decision hierarchy can manage exactly the same information that is necessary for achieving excellent business performance. Because, if the insight into the information is not complete, the analysis is based on the description of individual parts, i.e. proving partial performance in the realization of individual information, which can certainly create a space for the loss of the expensive time and energy. Illustratively, if the view, or insight into the information, is not 100%, then all business decision-making is like the song of J.J. Zmaj "Elephant", about an elephant and a blindmen, where everyone feels and act only on the base of the experienced work, and brings judgment on what is what or what can be. As in this song for children, everyone thinks that he touches different animals and when they make claims about what they feel, everyone describes a completely different life. Therefore, business intelligence implies that information is fully considered and it is basically the basis or knowledge base, and therefore the basis of business excellence. In doing so, the main problem is how information is transformed into knowledge and based on it in business decision making. It is precisely in this segment that the main advantage of business intelligence is its contribution to the knowledge and business of the company based on power of knowledge. Therefore, for modern business conditions, it is characteristic that the management of the company is realized on the basis of partial knowledge about stakeholders (buyers, suppliers, competitors, shareholders, governments, institutional framework, legislation), and only a complete overview of managers at the highest level in all these partial interest groups allows managers to have a “boat” called the organization of labor leading a safe hand through the storm, Scile and Haribde threatens to endanger business, towards a calm sea and a safe harbor - called a sustainable competitive advantage based on power and knowledge.

The aim of this study was to investigate the influence of clinical supervision on nurse’ moral decision making. The sample consisted of 15 registered nurses who took part in clinical supervision sessions. Data were obtained from interviews and analysed by a hermeneutic transformative process. The hermeneutic interpretation revealed four themes: increased self-assurance, an increased ability to support the patient, an increased ability to be in a relationship with the patient, and an increased ability to take responsibility. In conclusion, it seems that clinical supervision enhances nurse’ ability to provide care on the basis of their decision making. However, the qualitative and structural aspects of clinical supervision have to be investigated further in order to develop professional insight into the way that nurses think and react.

Purpose The purpose of this paper is to develop propositions explaining the influence of individual goals and social preferences on human decision making in transport planning. The aim is to understand which individual goals and social preferences planners pursue and how these influence planners’ decisions. Design/methodology/approach Propositions are developed based on investigation of decision making of transport planners in a Dutch logistics service provider using multiple data collection methods. Findings The study shows how decision making of transport planners is motivated by individual goals as well as social preferences for reciprocity and group identity. Research limitations/implications Further research including transaction data analysis is needed to triangulate findings and to strengthen conclusions. Propositions are developed to be tested in future research. Practical implications Results suggest that efforts to guide planners in their decision making should go beyond traditional (monetary) incentives and consider their individual goals and social preferences. Moreover, this study provides insight into why transport planners deviate from desired behaviour. Originality/value While individual decision making plays an essential role in operational planning, the factors influencing how individuals make operational planning decisions are not fully understood.

Abstract. Globally, many different kinds of water resources management issues call for policy- and infrastructure-based responses. Yet responsible decision-making about water resources management raises a fundamental challenge for hydrologists: making predictions about water resources on decadal- to century-long timescales. Obtaining insight into hydrologic futures over 100 yr timescales forces researchers to address internal and exogenous changes in the properties of hydrologic systems. To do this, new hydrologic research must identify, describe and model feedbacks between water and other changing, coupled environmental subsystems. These models must be constrained to yield useful insights, despite the many likely sources of uncertainty in their predictions. Chief among these uncertainties are the impacts of the increasing role of human intervention in the global water cycle – a defining challenge for hydrology in the Anthropocene. Here we present a research agenda that proposes a suite of strategies to address these challenges from the perspectives of hydrologic science research. The research agenda focuses on the development of co-evolutionary hydrologic modeling to explore coupling across systems, and to address the implications of this coupling on the long-time behavior of the coupled systems. Three research directions support the development of these models: hydrologic reconstruction, comparative hydrology and model-data learning. These strategies focus on understanding hydrologic processes and feedbacks over long timescales, across many locations, and through strategic coupling of observational and model data in specific systems. We highlight the value of use-inspired and team-based science that is motivated by real-world hydrologic problems but targets improvements in fundamental understanding to support decision-making and management. Fully realizing the potential of this approach will ultimately require detailed integration of social science and physical science understanding of water systems, and is a priority for the developing field of sociohydrology.
