Model-based testing with UML applied to a roaming algorithm for Bluetooth devices     

GRABOWSKI Jens  NEUKIRCHEN Helmut  PALS Holger 《Journal of Zhejiang University. Science. B》2004,(11)

INTRODUCTION The Unified Modeling Language (UML)(Eriksson, 2003) is a visual language supporting thedesign and development of complex object-orientedsystems. While UML models focus primarily on thedefinition of system structure and behavior, theyprovide only limited means for describing test ob-jectives and test procedures. Furthermore, thegrowing system complexity increases the need forsolid testing. Thus, in 2001, the Object Manage-ment Group issued a Request for Proposal (U…  相似文献   

Combining Environmental Education with Experience of Industry in Teacher Education     

Helmut Dahncke 《欧洲师范教育杂志》1997,20(2):151-159

Environment protection and environment education on the one hand and elements of a new way of teacher education linked with the general world of work on the other hand, basically form the frame of reference of this study. At first, both references came along independently of each other. In view of the political and educational actuality of environment education, however, both references can easily be combined. On the one hand, many teacher students, while working on their projects, take an interest in topics of environment protection and environment education on their own initiative. On the other hand, in the general world of work and industry these topics have been taken up as for instance in developing hydrogen energy engines. In this paper we deal with the field of solar hydrogen energy and the solar hydrogen cycle, from curricular points of view and in particular from the aspect of communication and acceptance. Thus it builds the bridge from the first point of reference, environment protection and environment education, to the second point of reference, the new concept of teacher education in combination with the general world of work and industry.  相似文献

Predicting Disordered Eating Intentions Among Incoming College Freshman: An Analysis of Social Norms and Body Esteem     

Steven M. Giles  Donald Helme  Marina Krcmar 《Communication Studies》2013,64(4):395-410

The purpose of this study was to explore the relationship between parental influence, peer norms, body esteem, and disordered eating intentions in a sample of incoming college freshmen women. A total of 427 incoming female college freshmen from a private university in the southeastern United States were surveyed as part of a larger study. Results indicated that body esteem moderated the relationship between parent thinness norms, parent encouragement norms, parent communicative norms, peer acceptability norms, and peer prevalence norms on disordered eating intentions. There was no significant interaction between body esteem and peer thinness norms. These results suggest that efforts to prevent disordered eating among college students should include strategies for changing normative influence, both from parents and peers.  相似文献   

A cross-national comparison of perceived strategic importance of RFID for CIOs in Germany and Italy     

Stefanie Leimeister  Jan Marco Leimeister  Uta Knebel  Helmut Krcmar 《International Journal of Information Management》2009

Purpose

Drawing from literature on innovation, strategy and culture the objective of this study is to explore the role of perceived potentials and perceived strategic importance on CIOs’ perspective on RFID technology in two different cultural settings.

Methodology

Based on survey responses from 463 German and 157 Italian IT decision makers we analyzed the data with PLS structural equation modeling.

Findings

We show that perceived potentials of RFID influence the perceived strategic importance which positively influences CIOs’ intention to invest in RFID. The composition of perceived potentials affecting the strategic importance of RFID differs significantly in both cultures. In Germany, potentials attributed to RFID are improving quality, automating manpower, reducing counterfeits, and improving customer service. Italian CIOs value reducing stock inconsistencies, optimizing stock keeping, and improving customer service as RFID potentials. Regardless of culture, findings show that company size hardly has impact on perceived strategic importance.

Originality/value

This research shows on a large empirical basis cultural differences in the perception of RFID in two countries using PLS.  相似文献   

惩罚性损害赔偿的欧洲视角     

Helmut Kozio  巫乐庭 《培训与研究》2009,26(5):78-84

这可能是不正确的,正如Sebok所指出的那样,惩罚性赔偿赔偿在美国早期的侵权法中主要是补偿性的功能,如美国最高法院在Cooper IndustriesInc案中所宣传的……首先,惩罚性赔偿的基础是对特定民事权利的侵害,此民事权利有别于完全被补偿性赔偿所纠正的民事权利体系。运用这一原则到我们的问题,我们得出如下结论：即使有很强的证据对被告人实施制裁,如果原告没有受到相应的损害,也没有对被告提出不当得利请求,那么这些证据不能单独证明原告有优势。……撇开惩罚性赔偿与私法的基本原则的不一致的事实,其也显示出一些另外的缺陷。……Colby称之为“总的损害”的惩罚性赔偿金：有可能一些受害者将获得旨在惩罚不法行为的整个计划的惩罚性损害赔偿金,从而导致不公正处罚的累积……一些欧洲的法律制度允许某些团体代表受害者的利益进行禁止令的申请和补偿的请求。  相似文献

Effects of Self‐Concept on Restoring a Positive Motivational State After an Exam‐Like Situation     

Sigrid Wimmer  Manuela Paechter  Helmut K. Lackner  Ilona Papousek 《Mind, Brain, and Education》2020,14(1):5-15

Exams often trigger avoidance motivation and a tendency to withdraw; instead, an approach‐oriented motivational state would be more desirable, since this encourages an invigorated and persistent approach to tasks. This study investigated the role of academic self‐concept on the activation of relative approach versus avoidance motivation during the course of an exam‐like situation. In 62 university students (50 women), academic self‐concept was assessed using self‐ratings, and activation of approach versus avoidance motivation was assessed by using the electroencephalogram alpha asymmetry response. Academic self‐concept proved to be an important moderator of motivational responses during the challenging situation. A more negative self‐concept was related to sustained decrease in approach motivation, to rumination, and to worsened mood. In contrast, a positive self‐concept was related to more positive mood and activation of approach motivation even beyond task completion. The findings have educational implications, for instance, for the design of exams and performance feedback.  相似文献
