International knowledge spillovers, especially through multinational companies (MNCs), have recently been a major topic of discussion among academics and practitioners. Most research in this field focuses on knowledge sharing activities of MNC subsidiaries. Relatively little is known about their capabilities for protecting valuable knowledge from spilling over to host country competitors. We extend this stream of research by investigating both formal protection strategies (e.g. patenting) as well as strategic ones (secrecy, lead time, complex design). We conceptualize the breadth of firm's knowledge protection strategies and relate it to the particular situation of MNC subsidiaries. Moreover, we argue that their approaches differ with regard to host country challenges and opportunities. We address these issues empirically, based on a harmonized survey of innovation activities of more than 1800 firms located in Portugal and Germany. We find evidence that MNCs prefer broader sets of knowledge protection strategies in a host country with fewer opportunities for knowledge sourcing (Portugal). In Germany, though, they opt for narrower sets of knowledge protection strategies if they invest in innovation activities themselves. We deduce that these results are due to a need for reciprocity in knowledge exchanges to benefit fully from promising host country knowledge flows. 相似文献

In this cross-national study, observed process quality in preschool classrooms was compared across five countries—Austria (n = 37), Germany (n=103), Portugal (n=88), Spain (n=80), and the U.S.A. (n=390). Process quality was assessed using the Early Childhood Environment Rating Scale (ECERS) and the Caregiver Interaction Scale (CIS). Both instruments had comparable properties when used in the different countries. A MANOVA found overall ECERS differences between countries, with Austria and Germany scoring higher than Spain, and Austria higher than the U.S.A. CIS Sensitivity scale differences showed Austria and Spain with higher scores than the U.S.A. Tests of homogeneity of variance showed U.S.A. with the highest standard deviations. A discriminant analysis, using countries as groups and ECERS items as criterion variables, revealed differences between countries on two discriminant functions: Personalized Care and Availability and Use of Space and Play Materials. Results are discussed in terms of the early childhood traditions and infrastructures found in the five countries. 相似文献

Zusammenfassung In diesem Beitrag wird der Versuch unternommen, das Verhältnis von allgemeiner und beruflicher Bildung einer skizzierenden konzeptionellen Analyse zu unterziehen. Im ersten Abschnitt wird die Aktualität der Integration beider Bildungsbereiche begründet und auf Missverständnisse Bezug genommen, die der Bewältigung dieser curricularen Aufgabe im Wege stehen. Im zweiten Abschnitt wird berufliche Bildung als ein Teilbereich besonderer Bildung definiert und zu den Stufen in Beziehung gesetzt, in denen sich allgemeine Bildung mit ihren inhaltlichen und methodischen Komponenten äussert. Die an allgemeinbildenden Sekundarschulen vermittelte studienbezogene Bildung erscheint in dieser Konzeption als Sonderfall beruflicher Bildung. Der Beitrag schliesst mit der Formulierung und Begründung dreier Thesen zur Notwendigkeit einer Lösung des Integrationsproblems und der Auswertung von Projekten, die unter verschiedenartigen didaktischen und organisatorischen Voraussetzungen durchgeführt werden.
This contribution attempts a broad conceptual analysis of the relationship between general and vocational education. In the first section the topicality of an integration of the two educational areas is shown, and reference is made to misunderstandings obstructing this curricular task. In the second section, vocational education is defined as one of several special types of education and related to the various levels of general education with their specific contents and methods. The preparatory courses for university provided in general, secondary schools appear in this concept as a special case of vocational education. Finally the article develops three theses on the necessity of resolving the integration problem and of evaluating projects that have been carried out under different didactic and organisational conditions.
Résumé L'auteur de cette étude procède dans les grandes lignes à l'analyse conceptuelle de la relation existant entre l'enseignement général et l'enseignement professionnel. Dans la première partie il montre l'actualité d'une intégration de ces deux domaines et signale les malentendus qui font obstacle à ce problème de curriculum. Dans la seconde partie l'auteur définit l'enseignement professionnel comme l'un des secteurs de l'enseignement spécial, secteur rattaché aux différents degrés de l'enseignement général avec leurs contenus spécifiques et leurs méthodes propres. L'enseignement dispensé dans les établissements secondaires de formation générale et préparant aux études supérieures apparaît dans ce concept comme un cas particulier d'enseignement professionnel. L'auteur conclut en formulant trois thèses sur la nécessité de résoudre le problème de l'intégration et d'évaluer les projets qui ont été appliqués dans des conditions didactiques distinctes et des organisations différentes.相似文献

The concept of “Home Learning Environment” (HLE) covers activities in a family providing intellectual stimulation for a child, such as reading to him or her or visiting libraries. Numerous studies have shown an association between HLE and children's cognitive development. In this longitudinal study, we focus on HLE as a predictor for children's behavioral development, namely, for later symptoms of attention-deficit hyperactivity disorder (ADHD), controlling for relevant aspects like socioeconomic status (SES), or television viewing behavior. We analyzed the development of ADHD symptoms from kindergarten to the end of grade 2 and possible associations with HLE, SES, and television exposure, using a German community sample (N?=?924). Results indicated that ADHD symptoms were negatively and significantly correlated to HLE for all five measurement points as well as to SES (except T4) and to television exposure for T1 to T4. Observing later development, only early HLE but not SES or television exposure served as a significant predictor for ADHD symptoms at school, when age, sex, and ADHD symptoms in kindergarten were controlled for. A structural equation model showed that HLE acted as a mediator between SES and later ADHD symptoms. Our results highlight the importance of the concept of home learning environment also for children's behavioral development. As a consequence, parents should be supported in offering their children a more favorable learning environment. 相似文献

When reading conflicting science-related texts, readers may attend to cues which allow them to assess plausibility. One such plausibility cue is the use of graphs in the texts, which are regarded as typical of ‘hard science’. The goal of our study was to investigate the effects of the presence of graphs on the perceived plausibility and situation model strength for conflicting science-related texts, while including the influence of readers’ amount of experience with scientific texts and graphs as a potential moderator of these effects. In an experiment mimicking web-based informal learning, 77 university students read texts on controversial scientific issues which were presented with either graphs or tables. Perceived plausibility and situation model strength for each text were assessed immediately after reading; reader variables were assessed several weeks prior to the experiment proper. The results suggest that graphs can indeed serve as plausibility cues and thus boost situation model strength for texts which contain them. This effect was mediated by the perceived plausibility of the information in the texts with graphs. However, whether readers use graphs as plausibility cues in texts with conflicting information seems to depend also on their amount of experience with scientific texts and graphs. 相似文献

This study examined the reading achievement, metacognitive knowledge related to reading and memory, reading self-concept, and interest in reading of 140 German school students in Grades 3 and 4. The results indicated significant correlations between the metacognitive variables, motivational variables, and amongst metacognitive and motivational variables, as well as with reading achievement variables. The examination of good and poor readers showed significant differences in metacognitive knowledge of reading and memory, reading self-concept, interest in reading, and in teacher judgements of reading achievement between the groups. Differences between Grade 3 and 4 students were found in their word decoding skills, metacognitive knowledge about reading and memory, and teacher judgements of reading achievement. Results of the regression analysis indicated that reading achievement was predicted by grade level, word decoding, and teacher evaluations of reading achievement. The causal modelling indicated that motivation and metacognition affect reading comprehension in different ways. The findings are discussed in terms of future research and their educational implications. 相似文献

Training consisting of numerous repetitions performed as closely as possible to ideal techniques is common in sports and every-day tasks. Little is known about fatigue-related technique changes that emerge at different timescales when repeating complex actions such as a karate front kick. Accordingly, 15 karatekas performed 600 kicks (1 pre-block and 9 blocks). The pre-block comprised 6 kicks (3 with each leg) at maximum intensity (K-100%). Each block comprised 60 kicks (10 with each leg) at 80% of their self-perceived maximum intensity (K-80%) plus 6 K-100%. In between blocks, the participants rested for 90 seconds. Right leg kinematics (peak joint angles, peak joint angular velocities, peak joint linear resultant velocities, and time of occurrence of peaks) and kick duration corresponding to the K-80% were measured resulting in numerous variations with fatigue. At the timescale of tens of seconds, the changes involved variables that were related to velocity of execution (slowed down), while variables related to movement form were hardly affected. At the timescale of tens of minutes, the opposite results were observed. These findings challenge the long-standing rationale underlying repetitive training, suggesting instead that such involuntary variations in technique might play a crucial role in motor skill training 相似文献

Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for measuring in the field are needed. This work analysed the accuracy and precision of a new wireless insole forcesensor for quantifying running-related kinetic parameters. Vertical ground reaction force (GRF) was simultaneously measured with pit-mounted force plates (1?kHz) and loadsol® sensors (100?Hz) under unshod forefoot and rearfoot running-step conditions. GRF data collections were repeated four times, each separated by 30 min treadmill running, to test influence of extended use. A repeated-measures ANOVA was used to identify differences between measurement devices. Additionally, mean bias and Bland–Altman limits of agreement (LoA) were calculated. We found a significant difference (p?.05) in ground contact time, peak force, and force rate, while there was no difference in parameters impulse, time to peak, and negative force rate. There was no influence of time point of measurement. The mean bias of ground contact time, impulse, peak force, and time to peak ranged between 0.6% and 3.4%, demonstrating high accuracy of loadsol® devices for these parameters. For these same parameters, the LoA analysis showed that 95% of all measurement differences between insole and force plate measurements were less than 12%, demonstrating high precision of the sensors. However, highly dynamic behaviour of GRF, such as force rate, is not yet sufficiently resolved by the insole devices, which is likely explained by the low sampling rate. 相似文献
