Large-scale information technology implementations are risky projects, and the challenges and risks multiply when multiple organizations are involved, as is often the case in e-government initiatives. Some of the risk can be addressed by carefully aligning the partners' motivations, which are affected by each organization's internal and external operational and information technology strategies. In this paper, we propose a strategic alignment framework and use it to examine the motivations of a set of collaborating government agencies and businesses in the pilot implementation of the Internet Payment Platform, an interorganizational, third-party hosted, e-procurement system. As we predict, the partners in this study had varied technical, political, economic, and operational motivations for participating in the project. Even so, the participating agencies reported positive outcomes from the project, and look forward to further collaboration on the next iteration of this e-procurement system. 相似文献

Effective processes, practices, and infrastructure are essential components of successful online teaching and learning efforts;
and they lead to a sense of faculty ownership of online teaching as well as enhanced support from an institution’s administration.
The institution’s recognition of faculty members’ efforts to teach online in relation to the traditional concepts of scholarship,
tenure, and promotion is an important motivational factor for sustaining effectiveness in the online learning environment.
This study examined institutional efforts to alleviate or overcome challenges faced by faculty members in creating and teaching
online courses, and we investigated faculty members’ perceptions regarding these institutional efforts. 相似文献

This article is about how Indigenous students from Year 7 to 10 at three government schools in the Australian Capital Territory (ACT) experience PE. The research question being, how do Indigenous students experience PE at the schools selected for the research? A process oriented approach was used to answer this question. In particular, figurational sociology was chosen because of its usefulness in interpreting sociological problems processually. The idea of the figuration or configuration was utilized to represent human power relationships, as well as systems and processes. The study also drew upon the complimentary figurational concept of habitus. An accompanying methodology sympathetic to figurational sociology reconstructed the macro and micro levels of the figuration studied. This figuration being the PE provision across the three sites. The macro level depicts the contemporary social structure or ‘rules’ of the figuration and the micro level the individuals that exist within this social structure. Data were collected over a two year period using semi-structured interviews, school websites, school based documentation and wider ACT Education and Training Directorate system level documents. The research found that Indigenous students experience almost entirely Eurocentric PE that lacks acknowledgment of their own culture. The PE provided is an example of ‘superior’ knowledge characteristic of dominant groups. The research also showed that the habituses of key players such as principals, Health and Physical Education curriculum writers and teachers were pivotal as long-term processes in upholding Eurocentric PE content. The findings suggest that for Indigenous perspectives to be included in PE as stipulated in national level documentation, policy directives alone are inadequate. For meaningful change to take place alteration at the habitus level of the mentioned key players has to occur and such change requires a multi-faceted approach. 相似文献

The purpose of the present study was to re-examine the relationship between deep body temperature and relative exercise intensity, during running rather than cycling (Saltin and Hermansen, 1966). Twenty male competitive and recreational distance runners, aged 22 + 0.9 years (mean +/- sx), were selected to form two groups, one with high maximal oxygen uptake (VO2max) values (72.8 +/- 0.8 ml x kg(-1) x min(-1)) and the other with moderate values (59.4 +/- 0.7 ml x kg(-1) x min(-1)). The participants completed two 60 min constant-paced treadmill runs at a common speed (absolute intensity) of 10.5 km x h(-1) and at a relative exercise intensity at a speed equivalent to 65% of VO2max. During the relative exercise intensity trial, no differences were found in rectal temperature, skin temperature or heart rate between groups. However, when running at the common speed, differences were identified in rectal temperature. At 60 min, rectal temperature was 37.70 +/- 0.19 degrees C and 38.19 +/- 0.11 degrees C for the high and moderate VO2max groups, respectively (P < 0.05). Sweat lost was significantly higher in the moderate VO2max group (moderate: 1.05 +/- 0.06 kg x h(-1); high: 0.82 +/- 0.08 kg x h(-1); P < 0.05). Heart rates were also different between groups over the first 20 min during the common speed trial (P < 0.05). The results of the present study support the findings of Saltin and Hermansen (1966), in that the set-point at which temperature is maintained is related to the relative exercise intensity. 相似文献

Quantum information theory holds the promise of revolutionizing technologies other than computing
and communications. In this article we show how quantum entanglement can be harnessed to beat the Rayleigh
diffraction limit of conventional optical lithography, and to permit nano-devices to be fabricated at a scale
arbitrarily shorter than the wavelength used. Given the relative ease of performing optical lithography
compared with other schemes, and the relative costs associated in migrating the lithography industry to
each new fabrication technology, exploiting quantum entanglement to extend the useful life of optical lithography
could be economically attractive. 相似文献

This article addresses how NASA uses inquiry in the classroom so that students can see learning in a whole new light. The goal is to increase scientific literacy among Americans and to entice a greater number of students to pursue careers in science, technology, engineering and mathematics. Although NASA offers a diverse array of programs that incorporate inquiry learning through a well-established distribution network, this article examines two programs: the Virtual Design Center (VDC), created by the Classroom of the FutureTM, and the NASA Explorer Schools program, one of four pathfinder initiatives that the Agency launched to inspire the next generation of space explorers. 相似文献

Talent identification and development in soccer 总被引:5,自引:5,他引:0
In this review, we attempt to integrate the main research findings concerned with talent identification and development in soccer. Research approaches in anthropometry, physiology, psychology and sociology are considered and, where possible, integrated. Although some progress has been made in identifying correlates of playing success, it appears that no unique characteristics can be isolated with confidence. Both biological and behavioural scientists have indicated a strong genetic component in performance of sports such as soccer; nevertheless, the influence of systematic training and development programmes should not be underestimated. We conclude that the sport and exercise sciences have an important support role in the processes of identifying, monitoring and nurturing talented soccer players towards realizing their potential. 相似文献

In this review, key components of perceptual skill in soccer are identified and implications for talent identification and development highlighted. Skilled soccer players can recall and recognize patterns of play more effectively than their less skilled counterparts. This ability to encode, retrieve and recognize sport-specific information is due to complex and discriminating long-term memory structures and is crucial to anticipation in soccer. Similarly, experts use their knowledge of situational probabilities (i.e. expectations) to anticipate future events. They have a better than average idea of what is likely to happen given a particular set of circumstances. Also, proficiency-related differences in visual search strategy are observed. Skilled players use their superior knowledge to control the eye movement patterns necessary for seeking and picking up important sources of information. The nature of the task plays an important role in constraining the type of search used. Skilled soccer players use different search strategies when viewing the whole field (i.e. 11 vs 11 situations) compared with micro-states of the game (i.e. 1 vs 1, 3 vs 3 situations). Visual search behaviour also differs between defensive and offensive plays. These observations have implications for the development of perceptual training programmes and the identification of potential elite soccer players. 相似文献
