BACKGROUND Big data in healthcare must be exploited to achieve a substantial increase in efficiency and competitiveness. Especially the analysis of patient-related data possesses huge potential to improve decision-making processes. However, most analytical approaches used today are highly time- and resource-consuming. OBJECTIVE The presented software solution Conquery is an open-source software tool providing advanced, but intuitive data analysis without the need for specialized statistical training. Conquery aims to simplify big data analysis for novice database users in the medical sector. METHODS Conquery is a document-oriented distributed timeseries database and analysis platform. Its main application is the analysis of per-person medical records by non-technical medical professionals. Complex analyses are realized in the Conquery frontend by dragging tree nodes into the query editor. Queries are evaluated by a bespoke distributed query-engine for medical records in a column-oriented fashion. We present a custom compression scheme to facilitate low response times that uses online calculated as well as precomputed metadata and data statistics. RESULTS Conquery allows for easy navigation through the hierarchy and enables complex study cohort construction whilst reducing the demand on time and resources. The UI of Conquery and a query output is exemplified by the construction of a relevant clinical cohort. CONCLUSIONS Conquery is an efficient and intuitive open-source software for performant and secure data analysis and aims at supporting decision-making processes in the healthcare sector.

Abstract Introduction This study aimed to explore the decision-making processes of raters during objective structured clinical examinations (OSCEs), in particular to explore the tacit assumptions and beliefs of raters as well as rater idiosyncrasies. Methods Thinking aloud protocol interviews were used to gather data on the thoughts of examiners during their decision-making, while watching trigger OSCE videos and rating candidates. A purposeful recruiting strategy was taken, with a view to interviewing both examiners with many years of experience (greater than six years) and those with less experience examining at final medical examination level. Results Thirty-one interviews were conducted in three centres in three different countries. Three themes were identified during data analysis, entitled ‘OSCEs are inauthentic’, ‘looking for glimpses of truth’ and ‘evolution with experience’. Conclusion Raters perceive that the shortcomings of OSCEs can have unwanted effects on student behaviour. Some examiners, more likely the more experienced group, may deviate from an organisations directions due to perceived shortcomings of the assessment. No method of assessment is without flaw, and it is important to be aware of the limitations and shortcomings of assessment methods on student performance and examiner perception. Further study of assessor and student perception of OSCE performance would be helpful.

Automated Decision Making

This article critically examines the opportunities and challenges that automated decision-making (ADM) poses for environmental impact assessments (EIAs) as a crucial aspect of environmental law. It argues that while fully or partially automating discretionary EIA decisions is legally and technically problematic, there is significant potential for data-driven decision-making tools to provide superior analysis and predictions to better inform EIA processes. Discretionary decision-making is desirable for EIA decisions given the inherent complexity associated with environmental regulation and the prediction of future impacts. This article demonstrates that current ADM tools cannot adequately replicate human discretionary processes for EIAs—even if there is human oversight and review of automated outputs. Instead of fully or partially automating EIA decisions, data-driven decision-making can be more appropriately deployed to enhance data analysis and predictions to optimise EIA decision-making processes. This latter type of ADM can augment decision-making processes without displacing the critical role of human discretion in weighing the complex environmental, social and economic considerations inherent in EIA determinations.

Nowadays, many organizations take Business Intelligence (BI) systems to improve their decision-making processes. Although many organizations have adopted BI systems, not all of these implementations have been successful. This paper seeks to identify critical success factors (CSFs) that impact on successful implementation of BI systems in organizations. So, at first, through literature review, 26 CSFs were identified. Following that, a questionnaire was developed and then filled out by domain experts who had at least three years of experience in BI implementation projects in Iran. Robust Exploratory Factor Analysis (EFA) was run for data analysis, which finally classified 26 CSFs into four distinct groups termed as “organizational”, “human”, “project management”, and “technical”. The results of this study provide a very useful reference for scholars and managers to identify the relevant issues of BI projects in Iran.

Decision Making Processes

In this article, findings from 300 standardized interviews with representatives of Civic Organizations in Ho Chi Minh-City and Ha Noi are presented. Following a view of civil society as a specific mode of social action and interaction, data analysis unveils the existence of core dimensions of such action (respect, empathy/ sympathy, and the willingness to compromise and stick to agreed-upon rules), though the respective values of those dimensions vary strongly. Inseparably linked with such civil society action of whatever kind is consensus-seeking, an aversion to conflicts, and an affinity to synthesis. These attitudes and practices, dominating various Civic Organizations’ internal decision-making processes, represent elements of authoritarian political thinking in Civic Organizations’ leaders’ mindsets and courses of action. Combined, those characteristics make up civil society action “in Vietnamese colours”.

O desenvolvimento de conteúdos tático-técnicos no processo de ensino-treino do futebol é atribuição fundamental do treinador, buscando coordenar e orientar possíveis ações de jogo dos atletas. Assim, o artigo objetiva analisar a concepção de treinadores das categorias de base de um clube de elite do futebol brasileiro sobre aspectos técnicos e táticos do plano, do treino e do jogo. Participaram de entrevista semiestruturada oito treinadores do sub-10 ao sub-17, sendo o tratamento das informações realizado por meio da análise de conteúdo. Nas temáticas de plano e treino, sete treinadores investigados visualizam e desenvolvem a técnica de forma descontextualizada da tática. Contraditoriamente, na temática referente ao jogo os treinadores avaliam o contexto tático do jogo, não atribuindo relevância para o aspecto técnico. Portanto, torna-se relevante o treinador ter coerência e compreender o processo de planejar, treinar e jogar de forma complementar, contextualizando o desenvolvimento da técnica e da tática.Resumen. El desarrollo de los contenidos táctico-técnicos en el proceso de enseñanza-entrenamiento del fútbol configura tarea central del entrenador, objetivando coordinar y orientar posibles acciones de juego de sus deportistas. Como un paisaje complejo que incluye constantemente el afrontamiento a los problemas tácticos-técnicos. En este sentido, se hace necesario que el entrenador comprenda estos problemas para que pueda guiar acciones tomadas por los jugadores. Así, esta investigación tiene como objetivo analizar la concepción de los entrenadores de las categorías inferiores de un club de elite del fútbol brasileño en los aspectos técnicos y tácticos del plan, el entrenamiento y el partido. Participaron de una entrevista semiestructura ocho entrenadores (del sub-10 al sub-17), y el tratamiento de datos realizados por el análisis de contenido. En las categorías plan y entrenamiento predominó la percepción y enseñanza de la técnica descontextualizada de la táctica. Contradictoriamente, en la categoría juego los entrenadores evalúan el contexto táctico del juego, sin valorar al aspecto técnico. Por lo tanto, se hace importante para el entrenador tener consistencia y comprender el proceso de planificación, entrenamiento y el juego de una manera complementaria, contextualizando el desarrollo de la técnica y la táctica. Abstract. Coaching tactical-technical competences is a central task for soccer coaches, as it aims to better organize athletes’ actions during games. In this sense, it becomes necessary for coaches to understand such problems, to stimulate players’ better decision-making processes. Therefore, this paper aims to analyze youth category soccer coaches´ conceptions about tactical and technical issues in planning, training, and competition, in an elite Brazilian soccer club. Semi-structured interviews were conducted with eight coaches (from U-10 to U-17); data analysis was performed through content analysis. In planning and training topics, most of the coaches view and develop technical training separated form tactical aspects. Contradictorily, in the theme referring to competition coaches evaluated the tactical context of games, whereas they considered technical aspects as non-relevant. Therefore, being coherent and understanding the processes of planning, coaching and playing in a complementary way, contextualizing the development of tactical and technical, becomes essential for any youth category coach.
