Vocational decisions are important decisions for adolescents. This article takes television effects into account. A literature review for the occupational world in TV programs reveals a strong focus on some occupations as well as small cultivation effects plus learning effects from mediated role models. A secondary analysis of 2 panel waves was undertaken to study the effect of media role models on occupational aspiration. Television usage in a program segment correlated with corresponding aspirations. A process models showed a strong effect of career aspiration in 1 panel wave on related television usage and career aspirations in the following panel wave. 相似文献

Objective
The aim of the current study was to evaluate the effect of ultraviolet (UV) photofunctionalization of dental titanium implants with exposure to the oral cavity on osseointegration in an animal model.Methods
Forty-eight titanium implants (Camlog® Conelog® 4.3 mmx9.0 mm) were placed epicrestally into the edentulous jaws of three minipigs and implant stability was assessed by measuring the implant stability quotient (ISQ). Prior to implantation half of the implants were photofunctionalized with intense UV-light. After three months, the implants were exposed and ISQ was measured again. After six months of implant exposure, the minipigs were sacrificed and the harvested specimens were analyzed using histomorphometric, light, and fluorescence microscopy.Main results
Forty-two of 48 implants osseointegrated. The overall mean bone-implant contact area (BIC) was (64±22)%. No significant differences were found in BIC or ISQ value (multivariate analysis of variance (MANOVA), P>0.05) between implants with and without exposure to UV photofunctionalization.Conclusions
No significant effects were observed on osseointegration of dental titanium implants nine months after exposure of UV photofunctionalization.64.

As research faculty with expertise in the area of host–pathogen interactions (HPI), we used a research group model to effect our professional development as scientific educators. We have established a working hypothesis: The implementation of a curriculum that forms bridges between our seven HPI courses allows our students to achieve deep and meaningful learning of HPI concepts. Working collaboratively, we identified common learning goals, and we chose two microorganisms to serve as anchors for student learning. We instituted variations of published active-learning methods to engage students in research-oriented learning. In parallel, we are developing an assessment tool. The value of this work is in the development of a teaching model that successfully allowed faculty who already work collaboratively in the research area of HPI to apply a “research group approach” to further scientific teaching initiatives at a research university. We achieved results that could not be accomplished by even the most dedicated instructor working in isolation. 相似文献

Die Bedeutung von Popmusik im Leben von Jugendlichen und jungen Erwachsenen wird meist nur im Hinblick auf ihre alltagspraktische Funktion oder den Gebrauch thematisiert, der von ihr gemacht wird. Ausgehend von einigen Anregungen aus ?sthetik, Biographieforschung und Bildungstheorie soll dagegen im vorliegenden Beitrag versucht werden, diese Sichtweise durch die Einbeziehung der Musik selbst auf eine Weise zu erweitern, die es erlaubt, die Auseinandersetzung mit Popmusik als ?sthetische Erfahrung ernst zu nehmen und damit auch die Frage nach ihrem m?glichen Bildungssinn neu zu stellen. Anhand einiger Beispiele aus einer Schreibwerkstatt, in der junge Erwachsene sich erinnernd mit ihren popmusikalischen Erfahrungen auseinander gesetzt haben, wird gezeigt, wie im je spezifischen Zusammenwirken von lebensgeschichtlichem Kontext, dem besonderem musikalischen Material und den Erfahrungen, die damit gemacht werden, neue Sinnschichten und Bedeutungen performativ hervorgebracht werden, die weder als „Ausdruck“ der jeweiligen Situation noch als blo?e „Projektionen“ von momentanen Stimmungen auf ein für sich genommen bedeutungsloses Klanggebilde verstanden werden k?nnen. Ihre Bedeutung für Bildungsprozesse erschlie?t sich freilich erst, wenn eher vom rezeptiven als vom souver?nen Selbst, eher von dem Leben, das wir leben, als von dem, das wir „führen“, ausgegangen wird. 相似文献

Abstract This article reviews empirically oriented studies from the United States and Europe concerning visitor experiences in museum exhibitions in order to pinpoint similarities and differences among them. In the last 20 years, only a few scholars have tackled this research question in multifaceted empirical ways, although some of them have done so extensively. By comparing theoretical and methodical issues, as well as important results, we are able to outline several analytical building blocks that compose a complex framework of visitor expectations, experiences, and outcomes. Gathering credible data on experiences of visitors in exhibitions or museums, a method dating back to the tracking records of Robinson (1928) , is an ongoing challenge for the empirically inclined science of museum studies. Social scientists at universities and museums have been asking for 20 years: What are the findings regarding factors, structures, and consequences of exhibition experiences? Where are the blind spots? Which questions should be researched? 相似文献

The impact of technology-push and demand-pull policies on technical change - Does the locus of policies matter? 总被引：1，自引：0，他引：1

How to foster technical change is a highly relevant and intricate question in the arena of policymaking. Various studies have shown that technology-push and demand-pull policies induce innovation. However, there is a lack of work that distinguishes between the loci of policy support when assessing the policy-innovation relationship. We address this gap by shedding light on the question how the innovation effects of domestic and foreign demand-pull and technology-push policies differ. Using solar photovoltaic modules as a research case we conduct a panel analysis on 15 OECD countries over the period 1978 through 2005 with patent data. Three key findings emerged: First, our analyses find no evidence that domestic technology-push policies foster innovative output outside of national borders. Second, both domestic and foreign demand-pull policies trigger innovative output in a country. Third, we detect no indication that market growth induced by domestic demand-pull policies leads to more national innovative output than market growth induced by foreign demand-pull policies. Consequently, demand-pull policies create significant country-level innovation spillovers, which could disincentivize national policymakers to engage in domestic market creation. Based on these findings we discuss the need to establish supranational demand-pull policy schemes in order to address the spillover issue. 相似文献
