The topics covered in this work present the approach, methodological grounds and tools used in the Active Search for ergonomics issues. This Active Search is a systematic approach for mapping ergonomic demands developed and applied in the case presented. This approach encompasses a procedure and software which will be presented in this work. The Active Search begins after the analysis of medical related absenteeism data. They indicate the sectors where there may be critical situations in which ergonomic intervention is needed. After that, the required tasks are identified for each sector. Those tasks are analyzed by workers who, individually, indicate the ones that are critical and, among these, they also study their level of criticality in a preestablished scale. Finally, the data are compiled and submitted to the validation and prioritization of workers. The process is a collective activity which involves all the workers of the sector and the supervisors. Later, the selected activities are sent for the ergonomic situation analysis. This is an action research grounded study. The results of this work have shown a method which helps the identification of the tasks considered critical by the workers and that helps in the synthesis of the collected data. The relations among demands for family and products; ergonomic demands from technology used in manufacturing; the production sector and its respective directors and single manufacturing units are presented in the moment of synthesis. In the view of the results for such synthesis, it is possible to identify the distribution in the company of the ergonomic demands, according to these categories. This can aid the organization to decide the strategies to reduce critical work situation and to determine the systematically operations of the action analysis as well as the ergonomic improvements for the project. In addition, other results of this study are presented as an approach in the analysis phase in the ergonomic demand, as an operant model and as a technological innovation. / Este estudo aborda a etapa de análise da demanda do programa corporativo de ergonomia de uma grande empresa do setor metal mecânico de alta agregação de valor, os tópicos abordados neste trabalho apresentam a abordagem, as bases metodológicas e o instrumental utilizado na Busca Ativa de questões de ergonomia, que é uma abordagem sistemática para o mapeamento de demandas de ergonomia desenvolvida e aplicada no caso apresentado. Esta abordagem engloba um procedimento e um software, os quais serão apresentados neste trabalho. A Busca Ativa se inicia após a análise dos dados de absenteísmo por razões médicas, estes dados indicam setores em que potencialmente existem situações críticas que precisam de intervenção ergonômica, em seguida, são levantadas, para cada setor identificado, as tarefas prescritas, estas são submetidas à análise dos operadores, estes (individualmente) indicam as tarefas críticas e, dentre essas, o nível de criticidade em uma escala pré-estabelecida, ao final os dados são compilados e submetidos à validação e priorização dos operadores, sendo esta uma atividade coletiva envolvendo todos os operadores do setor e a supervisão, posteriormente as atividades selecionadas são encaminhadas para a análise ergonômica da situação. Em termos metodológicos, esta dissertação se desenvolveu sob a perspectiva da pesquisa-ação. Como resultados, esta pesquisa apresenta um método que auxilia na identificação dos recortes de análise que foram considerados críticos pelos operadores, além disso, apresenta sínteses dos dados coletados, caracterizando de forma ampla a demanda na empresa onde o estudo foi aplicado. Nestas sínteses são apresentadas as relações entre demandas ergonômicas por tecnologia utilizada na fabricação, demandas por setor de produção e sua respectiva diretoria, demandas por unidade de produção e demandas por famílias de produtos. Em face aos resultados de tais sínteses, pode-se identificar como a demanda, em função destas categorias, está distribuída na empresa, auxiliando a organização na decisão de estratégias de mitigação de situações críticas de trabalho e, ainda, na operacionalização de forma sistemática das ações de análise e projeto de melhoria das condições ergonômicas. Além destes, são apresentados resultados da pesquisa enquanto abordagem na fase de análise da demanda, enquanto modelo operante e inovação tecnológica.

An increasing number of university freshmen has been observable in absolute number as well as percentage of population over the last decade. However, at the same time the drop-out rate has increased significantly. While a drop in attendance could be observed at the same time, statistics show that young professionals consider only roughly thirty percent of their qualification to originate in their university education. Taking this into consideration with the before mentioned, one conclusion could be that students fail to see the importance of fundamental classes and choose to seek knowledge elsewhere, for example in free online courses. However, the so acquired knowledge is a non-attributable qualification. One solution to this problem must be to make on-site activities more attractive. A promising approach for raised attractiveness would be to support students in self-regulated learning processes, making them experience importance and value of own decisions based on realistic self-assessment and self-evaluation. At the same time, strict ex-cathedra teaching should be replaced by interactive forms of education, ideally activating on a meta-cognitive level. Particularly, as many students bring mobile communication devices into classes, this promising approach could be extended by utilising these mobile devices as second screens. That way, enhanced learning experiences can be provided. The basic idea is simple, namely to contribute to psychological concepts with the means of computer science. An example for this idea are audience response systems. There has been numerous research into these and related approaches for university readings, but other forms of education have not been sufficiently considered, for example tutorials. This technological aspect can be combined with recent didactics research and concepts like peer instruction or visible learning. Therefore, this dissertation presents an experimental approach at providing existing IT solutions for on-site tutorials, specifically tools for audience responses, evaluations, learning demand assessments, peer discussion, and virtual interactive whiteboards. These tools are provided under observation of anonymity and cognisant incidental utilisation. They provide insight into students\' motivation to attend classes, their motivation to utilise tools, and into their tool utilisation itself. Experimental findings are combined into an extensible system concept consisting of three major tool classes: anonymous peer discussion means, anonymous control facilities, and learning demand assessment. With the exception of the latter, promising findings in context of tutorials are presented, for example the reduction of audience response systems to an emergency brake, the versatility of (peer) discussion systems, or a demand for retroactive deanonymisation of contributions. The overall positive impact of tool utilisation on motivation to attend and perceived value of tutorials is discussed and supplemented by a positive impact on the final exams\' outcomes. / Über die vergangene Dekade ist eine zunehmende Zahl Studienanfänger beobachtbar, sowohl in der absoluten Anzahl, als auch im Bevölkerungsanteil. Demgegenüber steht aber eine überproportional hohe Steigerung der Abbruchquote. Während gleichzeitig die Anwesenheit in universitären Lehrveranstaltungen sinkt, zeigen Statistiken, dass nur etwa ein Drittel der Berufseinsteiger die Grundlagen ihrer Qualifikation im Studium sieht. Daraus könnte man ableiten, dass Studierende den Wert und die Bedeutung universitärer Ausbildung unterschätzen und stattdessen Wissen in anderen Quellen suchen, beispielsweise unentgeltlichen Online-Angeboten. Das auf diese Art angeeignete Wissen stellt aber eine formell nicht nachweise Qualifikation dar. Ein Weg aus diesem Dilemma muss die Steigerung der Attraktivität der universitären Lehrveranstaltungen sein. Ein vielversprechender Ansatz ist die Unterstützung der Studierenden im selbst-regulierten Lernen, wodurch sie die Wichtigkeit und den Wert eigener Entscheidung(sfindungsprozesse) auf Basis realistischer Selbsteinschätzung und Selbstevaluation erlernen. Gleichzeitig sollte Frontalunterricht durch interaktive Lehrformen ersetzt werden, idealerweise durch Aktivierung auf meta-kognitiver Ebene. Dies ist vielversprechend insbesondere, weil viele Studierende ihre eigenen mobilen Endgeräte in Lehrveranstaltungen bringen. Diese Geräte können als Second Screen für die neuen Lehrkonzepte verwendet werden. Auf diese Art kann dann eine verbesserte Lernerfahrung vermittelt werden. Die Grundidee ist simpel, nämlich in der Psychologie bewährte Didaktik-Konzepte durch die Mittel der Informatik zu unterstützen. Ein Beispiel dafür sind Audience Response Systeme, die hinlänglich im Rahmen von Vorlesungen untersucht worden sind. Andere Lehrformen wurden dabei jedoch unzureichend berücksichtigt, beispielsweise Tutorien. Ähnliche Überlegungen gelten natürlich auch für bewährte didaktische Konzepte wie Peer Instruction oder Betrachtungen in Form von Visible Learning. Deshalb präsentiert diese Dissertation einen experimentellen Ansatz, informationstechnische Lösungen für vor-Ort-Übungen anzubieten, nämlich Werkzeuge für Audience Response Systeme, Evaluationen, Lernbedarfsermittlung, Peer Discussion, sowie virtuelle interaktive Whiteboards. Die genannten Werkzeuge wurden unter Beachtung von Anonymitäts- und Beiläufigkeitsaspekten bereitgestellt. Sie erlauben einen Einblick in die Motivation der Studierenden Tutorien zu besuchen und die Werkzeuge zu nutzen, sowie ihr Nutzungsverhalten selbst. Die experimentellen Ergebnisse werden in ein erweiterbares Systemkonzept kombiniert, das drei Werkzeugklassen unterstützt: anonyme Peer Discussion, anonyme Kontrollwerkzeuge und Lernbedarfsermittlung. Für die ersten beiden Klassen liegen vielversprechende Ergebnisse vor, beispielsweise die notwendige Reduktion des Audience Response Systems auf eine Art Notbremse, die Vielseitigkeit von (Peer-)Discussion-Systemen, oder aber auch der Bedarf für eine retroaktive Deanonymisierung von initial anonymen Beiträgen. Der allgemein positive Einfluss der Werkzeugnutzung auf die Motivation an Tutorien teilzunehmen sowie den wahrgenommenen Wert der Tutorien werden abschließend diskutiert und durch verbesserte Abschlussklausurergebnisse untermauert.

The object of this research was to develop an international market screening methodology which selects highly attractive markets, allowing for the ranges in diversity amongst organisations, countries and products. Conventional business thought is that, every two to five years, dynamic organisations which conduct business internationally should decide which additional foreign market or markets to next enter. If they are internationally inexperienced, this will be their first market; if they are experienced, it might be, say, their 100th market. How should each organisation select their next international market? One previous attempt has been made to quantitatively test which decision variables, and what weights, should be used when choosing between the 230 countries of the world. The literature indicate that a well-informed selection decision could consider over 150 variables that measure aspects of each foreign market's economic, political, legal, cultural, technical and physical environments. Additionally, attributes of the organisation have not been considered when selecting the most attractive short-list of markets. The findings presented in the dissertation are that 30 criteria accounted for 95 per cent of variance at cross-classification rates of 95 per cent. The weights of each variable, and the markets selected statistically as being the most attractive, were found to vary with the capabilities, goals and values of the organisation. This frequently means that different countries will be best for different organisations selling the same product. A
