In the project ‘Competence-Driven Project Portfolio Analysis’ (CDPPA), an integrated system for supporting R&D project selection, staff assignment and activity scheduling with special consideration of the strategic development of competencies has been designed and implemented prototypically. The system has been field-tested at the Electronic Commerce Competence Center (EC3), a public–private partnership R&D enterprise. Experiences from this trial application are summarised and discussed, particularly concerning data collection and competence measurement, the benefits and limits of the chosen multi-criteria decision analysis approach, the evaluation of introduced changes to the decision-making processes, and the transparency of the formal planning model and its components. 相似文献

Zusammenfassung Seit der Einführung von Use Cases hat deren Bedeutung zur Spezifikation von Anforderungen stetig zugenommen. Die Qualit?t
der Use Cases ist ein entscheidender Faktor für den Erfolg des Entwicklungsprozesses, da die meisten Entwicklungsschritte
auf den Use Cases aufbauen. Trotz der extremen Wichtigkeit der Qualit?t der Use Cases stellen die meisten use-case-basierten
Entwicklungsans?tze keine oder nur unzureichende integrierte qualit?tssichernde Ma?nahmen bereit (z.B. ad-hoc Empfehlungen,
Erstellungsrichtlinien, einige Checklisten zur Inspektion von Use Cases). Diese Techniken werden in den meisten F?llen unabh?ngig
voneinander eingesetzt, so dass bestimmte Fehlerklassen in den Use Cases durch mehrere Techniken, andere Fehlerklassen überhaupt
nicht adressiert werden. In diesem Artikel wird ein integrierter Ansatz vorgestellt, in dem Use Case Erstellungsrichtlinien,
Inspektionen und Simulation in systematischer Weise miteinander verknüpft werden. Der Ansatz basiert auf einer Fehlerklassifikation
für Use Cases, die als Grundlage dient, die verschiedenen Techniken auf bestimmte Fehlerarten zu fokussieren .
Since their introduction, use cases (UCs) have become increasingly important for the specification of software requirements. High quality UCs are a prerequisite for project success. Despite the high importance of their quality, UC driven approaches often lack systematic and integrated quality assurance techniques. Only ad-hoc recommendations, creation guidelines, and a few checklists for inspection are available in the literature. If at all, these techniques are developed and used separately, so that one class of defects is addressed by several techniques and other classes are not addressed at all. In this paper, we present an integrated approach that combines UC creation guidelines, UC inspections, and simulation in a systematic way. We base our combined approach on a defect classification for use cases. This classification enables the requirements engineer to focus the different techniques on different types of defects.

Diese Arbeit stellt ein Modell und ein System zur Steuerung von Exoskeletten mit Hilfe von elektrischen
Signalen vor, die an den Muskeln des Benutzers gemessen werden. Anhand dieser Signale wird der eigene Drehmomentbeitrag
des Benutzer zur gewünschten Bewegung abgesch?tzt, und ein einstellbarer Faktor bestimmt das vom
Exoskelett hinzugefügte Drehmoment in Bezug auf den Beitrag des Benutzers. Die Signale werden durch
ein komplexes biomechanisches Modell ausgewertet. 相似文献

This study used accelerometer and self-report measures of overall sedentary time (ST) and screen time behaviours to examine their respective associations with adiposity among UK youth. Participants (Year groups 5, 8, and 10; n=292, 148 girls) wore the SenseWear Armband Mini accelerometer for eight days and completed the Youth Activity Profile, an online report tool designed to estimate physical activity and ST.Stature, body mass and waist circumference were measured to classify adiposity outcomes (overweight/obese and central obesity). One-way between groups ANOVA and adjusted linear, logistic and multinomial logistic regression analyses were conducted. There was a significant main effect of age on total ST across the whole week (F(2, 289)=41.64, p≤0.001). ST increased monotonically across Year 5 (581.09±107.81 min·dˉ¹), 8 (671.96±112.59 min·dˉ¹) and 10 (725.80±115.20 min·dˉ¹), and all pairwise comparisons were significant at p≤0.001. A steep age-related gradient to mobile phone use was present (p≤0.001). ST was positively associated with adiposity outcomes independent of moderate-to-vigorous intensity physical activity (MVPA; p≤0.001). Engaging in >3 hours of video gaming daily was positively associated with central obesity (OR=2.12, p≤0.05) but not after adjustment for MVPA. Results further demonstrate the importance of reducing overall ST to maintain healthy weight status among UK youth. 相似文献

As an attempt to reach physically inactive young people, especially girls, organized spontaneous sport (OSP) was implemented as a part of the state programme ‘The Sports Lift’ (2010). Projects, however, tended to primarily attract physically active boys rather than the actual target group. This problem calls for a qualitative approach to gain further knowledge about the interplay within the activities. Accordingly, this study aims to examine young people’s experiences of OSP activities with focus on participation, leadership and determining processes. To fulfil this purpose, a case study design was implemented. Data were collected through observations (pilot study) and semi-structured interviews with participants. The theoretical point of departure is developmental ecology, emphasizing the individual’s interaction with the multilevel environment. Results show that OSP is experienced as different from conventional organized sport. Further, the domination of boys is made possible through upholding the masculine sports norm, which is actualized within determining processes. 相似文献

AbstractSport science is a relatively recent domain of research born from the interactions of different disciplines related to sport. According to the European College of sport science (http://sport-science.org): “scientific excellence in sport science is based on disciplinary competence embedded in the understanding that its essence lies in its multi- and interdisciplinary character”. In this respect, the scientific domain of neuroscience has been developed within such a framework. Influenced by the apparent homogeneity of this scientific domain, the present paper reviews three important research topics in sport from a neuroscientific perspective. These topics concern the relationship between mind and motor action, the effects of cognition on motor performance, and the study of certain mental states (such as the “flow” effect, see below) and motor control issues to understand, for example, the neural substrates of the vertical squat jump. Based on the few extensive examples shown in this review, we argue that by adopting an interdisciplinary paradigm, sport science can emulate neuroscience in becoming a mono-discipline. 相似文献
