Knowledge integration in the shadow of tacit spillovers: Empirical evidence from U.S. R&D labs

Integrating knowledge across a firm's value chain (e.g. between R&D, marketing and manufacturing functions), which we denote “Knowledge Integration” (KI), has been consistently found to be a strong predictor of product innovation performance in the management literature. Such cross-functional integration does not occur by chance, but by design, as a result of managerial practices and organizational arrangements. The significant heterogeneity characterizing the diffusion of cross-functional integration across firms is suggestive of the well-known tension between internal and external diffusion of knowledge. In this paper, we argue that the hidden cost of KI is to expose firms to a higher risk of knowledge leakages and provide the first systematic empirical evidence of this apparent tension between internal and external knowledge flows. Based on data from the CMU Survey (one of the rare datasets offering observables on both sides of the tension for a representative set of R&D active firms in the US), we investigate the impact of knowledge spillovers to competitors on internal cross-functional knowledge integration involving the R&D function among manufacturing firms. We find that the intensity of (tacit) R&D knowledge spillovers at the industry-level has a negative and significant impact on the likelihood that firms adopt or achieve KI. Our results therefore suggest that firms may trade their optimal innovative performance against superior appropriability of their rents.     

Comparison of Haptic and Biometric Properties,Bacterial Load,and Student Perception of Fixative Solutions: Formaldehyde Versus Chilean Conservative Fixative Solution with and without Formaldehyde in Pig Kidneys

One of the most widely used solutions to fix and preserve organic tissues is formaldehyde, despite reservations regarding its toxicity and the fact that formaldehyde-embalmed bodies lose their original characteristics. Anatomy laboratories have been replacing formaldehyde with solutions that retain the characteristics of fresh tissue. For this purpose, alternative solutions with a very low concentration of formaldehyde or without any formaldehyde have been analyzed. The objective of this study was to compare biometry, coloration, haptic properties, and bacterial load on animal specimens (pig kidneys) embalmed with formaldehyde, and with Chilean Conservative Fixative Solution with and without formaldehyde (formaldehyde chCFS and formaldehyde-free chCFS). Also, the perception of health and biological science students toward specimens treated with different solutions was assessed. The results indicated that there were no significant differences in specimens’ retraction, or bacterial load. Students showed a preference for organs embalmed in formaldehyde chCFS and formaldehyde-free chCFS; indicating that with these treatments they could better visualize structures and that the prosections had greater flexibility and the colors were more similar to those of fresh tissue. Additionally, students recommended the material embalmed in formaldehyde chCFS and formaldehyde-free chCFS for anatomy learning. In contrast, students indicated that formaldehyde-fixation negatively affected their practical experience. In conclusion, embalming with formaldehyde chCFS or formaldehyde-free chCFS provides an advantageous practical experience over the use of formaldehyde and may be an alternative to replace the use of formaldehyde in anatomy laboratories.     

Key values of a Dutch cooperation school and the practice of religious education

This article presents the results of a single case study from a cooperation school in the Netherlands. A cooperation school is the result of a merger between a public and a denominational school. Pupils from secular and religious backgrounds meet in the classroom. This religious diversity in this school is explored by an empirical research study. The research question was how key values of the school and of its teachers are exerted in religious education. Content analysis of interviews and videos of the ‘moment of contemplation’ show that there is a discrepancy between the school values and the practice of this moment. Conclusions concerning a social and a substantive perspective are drawn in the light of theoretical insight concerning diversity in religious education.     

Understanding of the alphabetic principle through invented spelling among hearing‐impaired children learning to read and write: experimentation with a pedagogical approach

Given the problems experienced by hearing‐impaired individuals in learning the written language, a pedagogical approach was tested. The study examined the links between the development of representations of alphabetic system and the results in reading and writing of first graders. In the study, there were 31 hearing‐impaired children and 25 hearing ones. Invented spelling was measured three times during the school year. Reading and writing tests were given at the end of the year. The results obtained revealed a similarity between the learning profile of the hearing‐impaired children and that of the hearing children. It also demonstrated the importance of the work done through invented spelling, among the hearing‐impaired children. Thus, like their hearing peers, hearing‐impaired children are able to use procedures to process the written word based on the alphabetic principle, but continuous support‐implying invented spelling constantly adjusted to the progression of their representations must be provided.     

Motivational Profile and Academic Achievement Among Students Enrolled in Different Schooling Tracks

From the contextual perspective, researchers argue that the relevance and weight of motivational variables of students' functioning vary depending on different dimensions related to individual, cultural or situational characteristics. The first objective of this study examined this contention by comparing self-perceptions of competence, learning goals and judgments of usefulness of school subjects as motivational determinants of high school students' commitment and achievement according to their assignment to their learning abilities. The second objective was to compare how these variables related to academic commitment and achievement according to the type of student and two school subjects. Two-hundred-and-twenty-six high school students from a same school participated sixty-one were learning disabled students, 60 were high achievers and 105 were average students. Findings suggest that the relevance of the motivational variables did not vary much across either the type of student or the school subjects. They also support Bandura's view about the primary role of self-perceptions of competence in students' academic commitment and achievement.     

Simulating Oppression: Digital Gaming,Race and the Education of African American Children

Educational game designers and educators are using digital games as a platform for teaching academic content, including multicultural curriculum. However, it is unclear how well digital game-based learning can coexist with the goals of multicultural education for the purpose of meeting the needs of African American children. In this essay, we raise serious questions about the use of digital games to teach about social oppression in ways that privilege the psychological well-being of African American children. We argue that digital games that intend to recreate histories of racial oppression can be harmful to African American children if they reproduce popular and problematic notions of indigenous lives and experiences. We illuminate some of the dangers of such digital games through a preliminary exploration of one digital game designed to teach about facets of African American enslavement. Our essay concludes with recommendations for culturally relevant digital game-based learning design and instruction.     

Region,Locality Characteristics,High School Tracking and Equality in Access to Educational Credentials: the case of Palestinian Arab communities in Israel

A limited number of studies attempted to account for regional and community‐level variables in exploring the mediating mechanisms conditioning the structure of educational opportunities. As a result, contextual dynamics of social stratification remain largely obscure. The aim of the present paper is to examine the relative effects of regional, locality (community level) and high school variables on access opportunities of Palestinian Arab high school pupils in Israel to educational credentials. The analysis is based on the aggregate data of 46 Arab localities. Findings reveal that while high school tracking patterns are affected by high school variables at community level (such as average allocation of teaching‐time per class and gender enrolment ratios), access to educational credentials (high school matriculation certificates) is determined by community‐level SES and the locality's geographic location (region). The implications of these findings for the broader study of issues related to equality in educational opportunities are discussed.
