University-industry research collaboration: a model to assess university capability     

Giovanni?AbramoEmail author  Ciriaco?Andrea?D’Angelo  Flavia?Di Costa 《Higher Education》2011,62(2):163-181

Scholars and policy makers recognize that collaboration between industry and the public research institutions is a necessity for innovation and national economic development. This work presents an econometric model which expresses the university capability for collaboration with industry as a function of size, location and research quality. The field of observation is made of the census of 2001–2003 scientific articles in the hard sciences, co-authored by universities and private enterprises located in Italy. The analysis shows that research quality of universities has an impact higher than geographic distance on the capability for collaborating with industry. The model proposed and the measures that descend from it are suited for use at various levels of administration, to assist in realizing the “third role” of universities: the contribution to socio-economic development through public to private technology transfer.  相似文献   

People and Technology Today： Some Educational Implications     

Alfredo Rodriguez-Sedano  Ana Costa Paris  Maite Dassoy Mut 《美中教育评论》2011,(5):627-636

The present article approaches some of the educational implications borne by humanity with technological progress We begin by pointing out significant data that classify what is considered relevant. Then, confronting the future is discussed by analyzing the attitudes necessary to promote the goals. Confronted with these challenges, three possible focuses are suggested in accordance to the novel realities issued from science and technology： The first is the revitalization of humanism; The second is, the society of knowledge calls for both ＂radicalism and responsibility＂, which is also a response to our own decisions, without avoiding their consequences nor discharging them in others; The third is, understanding the true and full significance of solidarity. Finally, some approaches and educational suggestions are highlighted allowing parents, professors and students the greatest opportunity for profiting from the limitless resources that science and technology provide us for personal growth.  相似文献

High-volume resistance training reduces postprandial lipaemia in postmenopausal women     

Cleiton Silva Correa  Bruno Costa Teixeira  Roberto Carlos Rebolledo Cobos  Rodrigo Cauduro Oliveira Macedo  Renata Lopes Kruger  Randall Bruce Kreismann Carteri 《Journal of sports sciences》2015,33(18):1890-1901

The aim of this study was to compare the effects of 11 weeks of low-volume resistance training (LVRT) and high-volume resistance training (HVRT) on muscle strength, muscle thickness (MT), and postprandial lipaemia (PPL) in postmenopausal women. Thirty-six healthy and untrained postmenopausal women (age, 58.9 ± 5.8 years; 68.6 ± 10.3 kg; and BMI, 26.9 ± 4.8 kg · m^?2) participated in resistance training 3× per week for 11 weeks (HVRT = 12; LVRT = 13; and control group = 11). Biochemical variables, both pretraining and post-training, were evaluated 16 h after the administration of an oral fat tolerance test (OFTT) and metabolic variable during [energy expenditure (EE)] and after training session [excess postexercise oxygen consumption (EPOC)]. Muscle strength (1 RM) and MT were also calculated, and no significant differences were observed between the groups for PPL (mmol · L^?1 per 5 h) as measured by glucose, high-density lipoprotein, low-density lipoprotein, and total cholesterol. EE total (EE + EPOC; 6.12 ± 1.21 MJ vs. 2.26 ± 0.85 MJ), resting fat oxidation (5.52 ± 1.69 g · h^?1 vs. 4.11 ± 1.12 g · h^?1); MT (vastus medialis, 21.4 ± 1.8 mm vs. 18.4 ± 1.2 mm and vastus lateralis 22.3 ± 1.2 mm vs. 20.8 ± 1.3 mm); triacylglycerol (TAG) 0, 1, 2, 4; and 5 h after OFTT, TAG area under the curve (AUC) (5.79 ± 0.42 vs. 7.78 ± 0.68), and incremental AUC (?46.21 ± 14.42% vs. 7.78 ± 4.68%) were all significantly different post-training for HVRT versus LVRT, respectively (P < 0.05). The results of this investigation suggest that HVRT reduces PPL in postmenopausal women.  相似文献   

On time-varying collaboration networks     

Matheus P. Viana  Diego R. Amancio  Luciano da F. Costa 《Journal of Informetrics》2013,7(2):371-378

The patterns of scientific collaboration have been frequently investigated in terms of complex networks without reference to time evolution. In the present work, we derive collaborative networks (from the arXiv repository) parameterized along time. By defining the concept of affine group, we identify several interesting trends in scientific collaboration, including the fact that the average size of the affine groups grows exponentially, while the number of authors increases as a power law. We were therefore able to identify, through extrapolation, the possible date when a single affine group is expected to emerge. Characteristic collaboration patterns were identified for each researcher, and their analysis revealed that larger affine groups tend to be less stable.  相似文献   

Five themes in a thought-full curriculum     

Arthur L. Costa 《Thinking Skills and Creativity》2006,1(1):62-66

Curriculum, instruction, learning and assessment are the pulse of the school. They are what drive everything else. They are the currency through which we exchange thoughts and ideas. They are the passions that bind our organization together. Educators recognize the growing need for informed, skilled, thoughtful and compassionate citizens who value truth, openness, creativity, interdependence, balance and love as well as the search for personal and spiritual freedom in all areas of one's life. This demands that the school's curriculum must be open and flexible enough to accommodate these new perspectives. In this article, five themes will be presented as “lenses” with which to view a thought-filled curriculum.  相似文献   

Observations sur la dimension pratique dans la formation des enseignants     

Maria Corda Costa 《欧洲师范教育杂志》1996,19(3):261-268

The strongpoints on which to plan the initial education and training of teachers are dealt with. On the training side two elements are considered: that part of training linked to learning processes, and the other part facing the social life of classroom and school, social and affective growth, civic education. It is advocated that the interaction between subject‐matter and its construction/transmission could take place through practical experimental paths within the actual work of school.  相似文献   

The difficulty of sit-ups tests: an empirical investigation.     

M J Safrit  W Zhu  M G Costa  L Zhang 《Research quarterly for exercise and sport》1992,63(3):277-283

This study estimated the difficulty of various sit-ups tests using an item response theory (IRT) model, the Rasch Poisson Counts model. Scores were obtained on 18 sit-ups tests. All tests were thought to vary in difficulty based on clinical observations. Item difficulty was defined by the Poisson model as the difficulty of Step 1, where the difficulty of a step represented the difficulty of completing a sit-up. The difficulty values of the tests ranged from -4.02 to -3.57. The easiest test was executed with hands on thighs and feet anchored. Most tests had good fit values. The results demonstrated that a variety of sit-ups tests can provide a range of difficulties and variety in forming a sit-ups test bank.  相似文献   

Engineered three-dimensional microfluidic device for interrogating cell-cell interactions in the tumor microenvironment     

K. Hockemeyer  C. Janetopoulos  A. Terekhov  W. Hofmeister  A. Vilgelm  Lino Costa  J. P. Wikswo  A. Richmond 《Biomicrofluidics》2014,8(4)

Stromal cells in the tumor microenvironment play a key role in the metastatic properties of a tumor. It is recognized that cancer-associated fibroblasts (CAFs) and endothelial cells secrete factors capable of influencing tumor cell migration into the blood or lymphatic vessels. We developed a microfluidic device that can be used to image the interactions between stromal cells and tumor cell spheroids in a three dimensional (3D) microenvironment while enabling external control of interstitial flow at an interface, which supports endothelial cells. The apparatus couples a 200-μm channel with a semicircular well to mimic the interface of a blood vessel with the stroma, and the design allows for visualization of the interactions of interstitial flow, endothelial cells, leukocytes, and fibroblasts with the tumor cells. We observed that normal tissue-associated fibroblasts (NAFs) contribute to the “single file” pattern of migration of tumor cells from the spheroid in the 3D microenvironment. In contrast, CAFs induce a rapid dispersion of tumor cells out of the spheroid with migration into the 3D matrix. Moreover, treatment of tumor spheroid cultures with the chemokine CXCL12 mimics the effect of the CAFs, resulting in similar patterns of dispersal of the tumor cells from the spheroid. Conversely, addition of CXCL12 to co-cultures of NAFs with tumor spheroids did not mimic the effects observed with CAF co-cultures, suggesting that NAFs produce factors that stabilize the tumor spheroids to reduce their migration in response to CXCL12.  相似文献   

Investigating how college students’ task definitions and plans relate to self-regulated learning processing and understanding of a complex science topic     

Jeffrey A. Greene  Leigh Anna HutchisonLara-Jeane Costa  Helen Crompton 《Contemporary educational psychology》2012

Winne and Hadwin (2008) identified four phases of self-regulated learning (SRL) including defining the task, setting goals and making plans, studying (i.e., learning), and adaptation. The vast majority of SRL research has focused on processing during the third phase, studying. In this study, we developed coding rubrics that allowed us to examine how the results of college students’ processing during phases one and two of Winne and Hadwin’s model, task definitions and plans, affected their SRL processing while learning with a hypermedia learning environment (HLE), and their subsequent academic performance. Our findings showed that, on average, participants gained both factual knowledge and integrated conceptual understanding over the course of learning with the HLE. The quality of participants’ task definitions and plans at pretest, as well as their SRL processing during learning, were related to learning outcomes. On average, participants’ task definitions improved from pretest to posttest. The findings from this study and the associated coding methodologies have implications for educational research and practice.  相似文献
