Opening the ivory tower's door: An analysis of the determinants of the formation of U.S. university spin-off companies     

Albert N. Link  John T. Scott 《Research Policy》2005,34(7):1106-1112

This paper presents findings from an analysis of the determinants of the formation of university spin-off companies within the university's research park. We find that university spin-off companies are a greater proportion of the companies in older parks and in parks that are associated with richer university research environments. We also find that university spin-off companies are a larger proportion of companies in parks that are geographically closer to their university and in parks that have a biotechnology focus.  相似文献

Research on a modified framework of implicit personality theories     

Albert Ziegler  Heidrun Stoeger 《Learning and individual differences》2010,20(4):318-326

There is ample evidence that labeled gifted students exhibit maladaptive behavior patterns. According to Carol Dweck those students who subscribe to a fixed view of their abilities are particularly at risk. In this contribution we extended Dweck's framework and distinguished two aspects of the implicit theory of one's own abilities. We hypothesized that the negative consequences of a fixed view are limited to the belief that one's own deficits are stable. In contrast, we assumed that the belief in the stability of existing abilities as well as the belief in the modifiability of ability deficits is adaptive. In two longitudinal studies with students from grades 7 to 10 we found supportive evidence for the proposed distinction.  相似文献   

Cleaning the slate? School choice and educational outcomes in Spain     

Cecilia Albert  Carlos García-Serrano 《Higher Education》2010,60(6):559-582

Using data from a nation-wide survey on Spanish workers, this paper examines two issues: the determinants of school choice (distinguishing between public and private schools) and the influence of school type on the individual’s educational attainment. For that, bivariate probit models are estimated. The analysis is carried out separately by gender and birth cohort. We find that individuals who have attended a private school come from households with higher socio-cultural level and that having attended a private school does not raise the probability of reaching a higher degree, once potential endogeneity of school choice and educational outcomes are taken into account. However, the latter result depends on the instrumental variable used for observed school type in models of demand for higher education.  相似文献   

Gender,complexity, and science for all: Systemizing and its impact on motivation to learn science for different science subjects          下载免费PDF全文

Albert Zeyer 《科学教学研究杂志》2018,55(2):147-171

The present study is based on a large cross‐cultural study, which showed that a systemizing cognition type has a high impact on motivation to learn science, while the impact of gender is only indirect thorough systemizing. The present study uses the same structural equation model as in the cross‐cultural study and separately tests it for physics, chemistry, and biology. The model was confirmed for physics and chemistry, but not for biology. This is interpreted as empirical evidence for a cognitive difference between the learning of hard sciences (like physics and chemistry) and life sciences (like biology) that reflects an epistemological difference between ordered (linear) and complex (non‐linear) systems. It is concluded that a more prominent inclusion of complex issues into science teaching could motivate low and average systemizers, independent of their gender, for science learning, that is, could be a key to science for all. Thus, there is a mutual benefit between important 21st century's issues of science teaching and the need to foster students’ motivation to learn science. © 2017 Wiley Periodicals, Inc.

The role of online communities of practice in promoting sociotechnical capital among science teachers     

Rita Karam  Susan G. Straus  Albert Byers  Courtney A. Kase  Matthew Cefalu 《Educational technology research and development : ETR & D》2018,66(2):215-245

This study explores the diffusion of Web 2.0 technologies among science educators and the ways that these technologies are used to build teacher professional communities of practice (CoP) in life sciences and physical sciences. We used surveys and web analytics collected over a 21-month period to examine factors that motivate teachers to collaborate in these CoPs and the extent to which collaborative participation contributes to the development of sociotechnical capital and job outcomes, such as instructional practices and self-efficacy for science instruction. Results showed that only the lack of co-located peers at teachers’ schools predicted CoP participation. Participation did not predict job outcomes, but it did predict some aspects of sociotechnical capital, such as a cohesive climate and situated knowledge. In addition, sociotechnical capital was associated with job outcomes, including use of inquiry-based instruction, use of inquiry-based classroom activities and teacher self-efficacy. The lack of effect of most of the antecedent variables in predicting participation and the relatively minor role of participation in contributing to sociotechnical capital and job outcomes may be explained by floor effects on participation due to infrequent and ephemeral engagement of CoP members. Although participation rates were generally low, the positive association of participation with sociotechnical capital as well as generally favorable ratings of sociotechnical constructs suggest that online CoPs may have value for distributed science educators. Future research should address whether persistent participation by individuals is needed to build and sustain sociotechnical capital in online CoPs and to enhance development of participants’ teaching attitudes/practices.  相似文献   

An Evaluation of Videomodeling on Fundamental Motor Skill Performance of Preschool Children     

Iva Obrusnikova  Albert Cavalier 《Early Childhood Education Journal》2018,46(3):287-299

Proficiency in fundamental motor skills (FMS) is important for both the health and the overall growth and development of young children. To identify factors that facilitate the development of FMS, the study provided preliminary data on the effect of videomodeling (VM) on the acquisition of FMS by typically developing young children. Participants were six conveniently selected typically developing preschool-age children from an early care and education center. A multiple-baseline-across-participants single-subject research design was used to evaluate VM effects. Motor skill acquisition was assessed with validated developmental sequences of the standing long jump and the overarm throw. The results demonstrated that the VM intervention improved participants’ FMS performance and the improvement was maintained even after the withdrawal of the VM, 2 weeks after the last VM session. Qualitative data collected via a self-report enjoyment scale and field notes with the instructors elicited four factors that might have affected participants’ performance: their attention and motivation to perform the task and the skill complexity and reproduction. The data suggest that VM may be an efficient strategy for teaching FMS to preschool-age children.  相似文献   

The home advantage in sport competitions: Courneya and Carron's (1992) conceptual framework a decade later     

Albert V Carron  Todd M Loughhead  Steven R Bray 《Journal of sports sciences》2013,31(4):395-407

This paper had three aims. The first was to review research carried out on the home advantage from 1992 to the present. The second was to examine the extent to which a conceptual framework proposed by Courneya and Carron () was/is viable as a tool to highlight and organize an understanding of the home advantage. The final aim was to provide suggestions for future research.  相似文献   

Physical Fatigue and Motor Learning     

Albert V. Carron 《Research quarterly for exercise and sport》2013,84(4):682-686

Abstract

In an attempt to investigate the effects of physical fatigue upon the learning of a motor skill, 75 college women were assigned in systematic rotation to either a control group or to one of two experimental groups (N = 25 in each group). All subjects were given a total of 50 trials on the pursuit rotor: 25 trials on Day 1, the practice session; and 25 trials on Day 2, the test session. One of the experimental groups was fatigued early in the practice session while the other was fatigued late in the practice session. Fatigue interpolated early and late was detrimental to subsequent performance improvements but had no effect upon the amount learned.  相似文献   

Effects of Ventilation on Segmental Bioimpedance Spectroscopy Measures Using Generalizability Theory     

A. Allan Turner  Albert Lozano-Nieto  Marcel Bouffard 《Measurement in physical education and exercise science》2013,17(2):116-129

The purpose of this study was to examine the effect of three ventilation conditions (i.e., normal, regimented, and no-ventilation) on the reproducibility of bioimpedance scores in humans for the forearm and trunk segments. One hundred able-bodied North American men and women, from 18 to 71 years of age, volunteered as participants. The experimenters used a Xitron Bio-Impedance Analyzer System model 4200 instrument with Hydra software (Xitron Technologies, San Diego, California, USA) to collect bioimpedance data on extracellular fluid and intracellular fluid scores. The experimenters analyzed the data using the generalizability theory,with persons as the facet of differentiation and time as the facet of generalization. The major findings were (a) ventilation conditions did not have a significant impact on the reproducibility of the test scores, (b) the forearm segment produced consistently higher intracellular fluid generalizability coefficients across three ventilation conditions for both gender groups when compared to the trunk segment, (c) the trunk segment produced intracellular fluid generalizability coefficients that were higher for the male group, and (d) the measurement error affected extracellular fluid scores less than segmental intracellular fluid scores.  相似文献
