This paper exploits discontinuities and randomness in the college admissions in Sweden in 1982, to estimate the economic return to college in the 1990s. At the time, college admissions were highly selective and applicants were ranked with respect to their formal merits. Admissions were given to those ranked higher than some threshold value. At the margin, applicants were sometimes randomly assigned to college. Exploiting this Regression-Discontinuity design, individuals who were admitted in 1982 are estimated to have about 0.20 years longer college education in 1996. However, the earnings effects for applicants at the margin of admission are insignificant. Controlling for the college admission determinants, the OLS-estimates of the return to college is 1.4 percent in 1991–96. The IV-estimates are not significantly different from the OLS counterparts. 相似文献

Although often downplayed and instrumental, there is evidence that communication in projects is essential in achieving value creation. Our main interest in this paper is on temporary continuity, a situation where the temporary becomes a permanent condition in social systems. The question that we have address is: What characterizes project communication in a situation with temporary continuity?We argue for the need to transform communication processes into communication capabilities. In a situation with temporary continuity, there is a need to connect to a large number of value-creating processes, and communicating capabilities need to be a part of a communication system, where the aim is to bind together value-creating processes and communication capabilities. We construct a viable system consisting of five sub-systems. To become a viable system, projects in the form of temporary continuity, must handle the potential conflict between a culture of performance and a culture of innovation. This involves developing social mechanisms for coordination and interaction, with a focus on developing communication capabilities, in parallel with focusing on all of the five value-creation processes. 相似文献

The focus of this paper is on a group of pupils with reading and writing difficulties who have been participating in an intervention study using assistive technology. That intervention study contained supervised training sessions with reading and writing tasks using an iPad with special supportive applications. The current study is a qualitative investigation of whether there has been any transfer from the intervention, to the pupils’ everyday school activities. Interviews with pupils and their teachers and observations during classroom lectures have been used to collect data. The results show that the pupils were positive to the assistive technology (the applications on the iPads), they found the apps easy to learn how to use and they appreciated the benefits they could give. Even so, only a few of the pupils had found use for and continued to use the tools after the intervention period finished. Possible reasons are that when the novelty wore off, students reverted to their usual study habits and that older students with many teachers and different classrooms were less able to adapt to using the apps. To improve transfer, it is suggested to introduce assistive technology earlier to students, in the younger grades, before study habits have been formed and to inform teachers about the use of AT in the classroom, including what is available and how it can benefit students. 相似文献

This article discusses models for religious education in school in (parts of) the Muslim world and the implied relation between self and other, confessional and national identity. The question of how current models and discussions respond to globalized issues in education is also discussed. The last part of the article identifies triggering factors behind some recent attempts at establishing more inclusive ways of teaching about religion and ethics in school. 相似文献

This paper will critically examine how the two influential pedagogical approaches of action-based learning and constructive alignment relate to each other, and how they may differ in focus and basic assumptions. From the outset, they are based on similar underpinnings, with the student and the learning outcomes in the center. Drawing from experiences of developing an action-based master program in management with the integration of constructive alignment in its curriculum, the purpose is to reflect on what difficulties emerge when adopting both perspectives simultaneously. Constructive alignment works under the premises that the learning goals can and should be decided beforehand in order to align them with learning activities and examination forms. This view brings a challenge for programs where the means of the learning process is provided, while it is much up to the students’ own responsibilities to drive the learning toward some self-governing and internalized learning outcomes. 相似文献

This paper reports on the international research and development (R&D) investments of German multinational corporations (MNCs). Based on a detailed empirical survey of laboratory sites established by 49 German MNCs, we examine (i) the level and pace of R&D internationalization, (ii) the motivations and mandates of overseas R&D laboratories, as well as (iii) the strength of the laboratories’ internal and external ties. Participating firms account for about 46% of all German enterprises with international R&D activities and approximately 66% of the nation's privately funded R&D expenditures in 1999. The findings indicate that the timing and organization of German owned overseas R&D investments more closely resemble Japanese or French than US or Swedish firms. Furthermore, in line with prior studies, German MNCs increasingly invest in international R&D for resource as opposed to market-seeking motives. The paper also finds significant differences with regard to the laboratory's mission and its geographical location on one hand, and its internal and external embeddedness, on the other. 相似文献

Zusammenfassung.
Die Beweisentwicklungsumgebung -Mkrpsoll
Mathematiker bei einer ihrer
Hauptt?tigkeiten, n?mlich dem Beweisen mathematischer Theoreme
unterstützen. Diese Unterstützung mu? so komfortabel sein,
da? die
rechnergestützte Suche nach formalen Beweisen leichter und insbesondere
weniger aufwendig ist, als ohne das System. Dazu mu? die verwendete
Objektsprache ausdrucksstark sein, man mu? die M?glichkeit haben, abstrakt
über Beweispl?ne zu reden, die gefundenen Beweise müssen in einer am
Menschen orientierte Form pr?sentiert werden und vor allem mu? eine
effiziente Unterstützung beim Füllen von Beweislücken zur Verfügung
stehen. Das im folgenden vorgestellte $\Omega$-Mkrp-System ist
der Versuch einer
Synthese der Ans?tze des vollautomatischen, des interaktiven und des
planbasierten Beweisens. Dieser Artikel soll eine übersicht über unsere
Arbeit an diesem System geben.

This paper presents an example of the use of patent statistics as a technology indicator in one industry. The first part deals with the problem of interpretation. Through examination of several other partial technology indicators, it is concluded that at least in this industry, patent statistics provide a reliable indicator, not only for the timing of inventions, but for the timing of innovations and diffusion as well. The reason is that the intervals between the stages in the innovation process are very short. This contradicts evidence from many other industries, and it is therefore emphasized that generalizations are unwarranted.The second part of this paper deals with the possible causes of technological change in Norwegian whaling. The methodology is inspired by J. Schmookler's work. Thus, the patents are correlated with other indicators of economic development in the industry. But while Schmookler's view is that the patent activity is determined by social demand and economic growth, the conclusions for the Norwegian whaling industry point in the opposite direction: the technological transformation that took place during the 1920s and early 1930s was forced upon the firms in their efforts to cut costs, which was achieved by rationalizing production and catching methods in line with a downward price trend for whale oil. 相似文献
