The relational antecedents of project-based enterprises have not yet received systematic investigation. These ventures are typically created by individual freelancers who are usually embedded in networks of collaborative relationships that convey the information and resources required to carry out new projects. Using a relational perspective of entrepreneurial discovery and team composition, we analyze the performance determinants of project-entrepreneurs, namely the individuals who are responsible for launching and carrying out those projects. We argue that project-entrepreneurs’ performance is related to their degree of centrality within the social network, and their familiarity with the selected project-team as captured by the distribution of ties among team members. We test our hypotheses within the Hollywood Film Industry over the period 1992–2003. The findings point to the existence of diminishing returns to centrality and performance benefits from assembling teams that combine old-timers and newcomers. The theoretical contributions and implications of the study are discussed.  相似文献   

The impact of high school exit exams on graduation rates and achievement     

Katherine Caves  Simone Balestra 《The Journal of educational research》2018,111(2):186-200

The authors examined the short- and long-term effects of high school exit exams (HSEEs) on graduation rates and achievement using an interrupted time series approach. There is a positive overall effect of HSEE introduction for graduation rate trends, which is heterogeneous over time. HSEEs have a negative impact on graduation rates in the year of introduction and briefly after, which is short lived and becomes positive (but not statistically significant) over the long term. There is also a preintervention negative effect, suggesting that high schools prepare for the HSEE before introduction. There are no effects for achievement, possibly due to the lack of meaningful cross-state achievement data. The findings are robust to the inclusion of states that do not have HSEEs as a control group and also robust to controlling for No Child Left Behind introduction.  相似文献

Age of entry,sex, and academic achievement in elementary school children     

John D. Sweetland  Philip A. De Simone 《Psychology in the schools》1987,24(4):406-412

It was hypothesized that children who enter school at a relatively early age do less well on standard measures of school achievement than do their older peers. One hundred fifty-two children born in 1970 and attending grades one through six in an upper-middle-class, suburban school district were studied. In general, it was found that children born in the later quarters of the year did, in fact, perform less well than children in the same grade born earlier through grades one to four. Analyses of covariance yielded a main effect for birth quartile (p < .05) in most cases. A significant main effect for sex was found for language scores at grades two and three. Implications of these findings for age of school entry, educational programming, and screening procedures are discussed.  相似文献

The educational cost of philosophical suicide: What it means to be lucid     

Simone Thornton 《Educational Philosophy and Theory》2019,51(6):608-618

The struggle to become lucid is at the heart of The Myth of Sisyphus. To understand the absurd is to understand that the fit between our conception of the world and the world itself is fraught with uncertainty; lucidity is the elucidation of the absurd. To be lucid is to revolt against the type of certainty that leads to suffering; to revolt against philosophical suicide. Camus teaches us the intellectual humility that stays hands; there is no reasoning that justifies suffering. If it is granted that the ability to recognise and respond to our own and others suffering is an important part of being human, and the task of education is to develop humans, then lucidity, in so far as it holds promise for the development of such an ability, has the potential to contribute positively to education.  相似文献

Beurteilereffekte bei der Messung von Unterrichtsqualität     

Dipl.-Päd. Marcus Pietsch  Dr. Simone Tosana 《Zeitschrift für Erziehungswissenschaft》2008,11(3):430-452

In the external evaluation of schools the technique of classroom observation belongs to the methodological standard repertoire. Nevertheless the measurement of quality of classroom teaching based upon selected lesson sequences, which are as a rule inspected only briefly, is fraught with a lot of methodological problems. Therefore it is relevant for a substantiated quality assurance to reveal problems in the measurement of quality of classroom teaching due to an implementation of adequate empirical methods. This is made possible by using the generalizability theory and the many-facet Rasch model. Analyses based upon data of the Hamburg school inspection point out that by using an appropriate data collection procedure rater effects in classroom observations turn out comparatively low at about nine percent of total variance. Furthermore analyses prove that it is insufficient to simply quantify the agreement among raters by using global reliability measures, but that it is necessary to check up on intra rater consistency for getting valid and in this way reliable results from classroom observations for the practice.  相似文献   

When Do Pictures Help Learning from Expository Text? Multimedia and Modality Effects in Primary Schools     

Simone Herrlinger  Tim N. Höffler  Maria Opfermann  Detlev Leutner 《Research in Science Education》2017,47(3):685-704

Adding pictures to a text is very common in today’s education and might be especially beneficial for elementary school children, whose abilities to read and understand pure text have not yet been fully developed. Our study examined whether adding pictures supports learning of a biology text in fourth grade and whether the text modality (spoken or written) plays a role. Results indicate that overall, pictures enhanced learning but that the text should be spoken rather than written. These results are in line with instructional design principles derived from common multimedia learning theories. In addition, for elementary school children, it might be advisable to read texts out to the children. Reading by themselves and looking at pictures might overload children’s cognitive capacities and especially their visual channel. In this case, text and pictures would not be integrated into one coherent mental model, and effective learning would not take place.  相似文献
