Linking university and industry: An organizational experience in Mexico     

Mario Waissbluth  Gustavo Cadena  Jose Luis Solleiro 《Research Policy》1988,17(6)

This paper describes the experience gained in the Center for Technological Innovation since its creation three years ago within the National Autonomous University of Mexico. By offering the services of locating clients, drafting and negotiating contracts, providing specialized information services, and project follow-up, the Center pursues the establishment of effective ties between University projects and industrial production. In so doing, its staff informally assumes the critical “dgate-keeper” and “entrepreneur” roles, not easily accepted in other areas of the University.The main difficulties encountered so far have been in developing interdisciplinary projects, providing due academic recognition for technological activities and extending knowledge about innovation throughout the University. On the other hand, a great advantage is the interest shown by the academic community; likewise is UNAM's stability and autonomy, structural characteristics which have stimulated the development of technically sound teams over several decades. To date, the Center has provided support services for 125 projects and has participated in establishing 44 contracts between the University and industry.  相似文献   

Contrasting AAC and ABC renewal: the role of context associations     

Laborda MA  Witnauer JE  Miller RR 《Learning & behavior》2011,39(1):46-56

Rats were used in a lick suppression preparation to assess the contribution of conditioned-stimulus (CS)–context and context–unconditioned-stimulus (US) associations to experimental extinction. Experiment 1 investigated whether strengthening the CS–acquisition context association enhances extinction by determining whether stronger extinction is observed when CS-alone trials (i.e., extinction treatment) are administered in the acquisition context (AAC renewal), relative to a context that is neutral with respect to the US (ABC renewal). Less recovery of responding to the CS was observed in the former than in the latter case, extending the finding that AAC renewal is weaker than ABC renewal to our lick suppression preparation. Experiment 2 assessed the contribution of the acquisition context–US association to extinction of a CS by examining the effect of postextinction exposure to the acquisition context on responding to the extinguished CS. This manipulation enhanced responding to the extinguished CS in AAC, but not ABC, renewal. Experiment 3 addressed the contribution of the CS–acquisition context association by examining the potential of a neutral stimulus, presented in compound with the target CS during extinction treatment, to overshadow the CS–acquisition context association. This manipulation enhanced responding to the extinguished CS in AAC, but not ABC, renewal. The results stress the important role of contextual association in extinction and renewal.  相似文献   

Alternative education programmes and middle school dropout in Honduras     

Jeffery H. Marshall  Claudia R. Aguilar  Mario Alas  Renán Rápalo Castellanos  Levi Castro  Ramón Enamorado  Esther Fonseca 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2014,60(1):51-77

Honduras has made steady progress in expanding post-primary school coverage in recent years, but many rural communities still do not provide a middle (lower secondary) school. As a result, Honduras has implemented a number of middle school alternative programmes designed to meet the needs of at-risk populations throughout the country. This article analyses dropout in three of the four main alternative lower secondary school programmes in Honduras over a three-year period for a cohort of roughly 5,500 students. The results show that these programmes are indeed reaching a vulnerable population in the country, but dropout rates are generally very high – upwards of 50 per cent in some cases – between Grades 7 and 9. Furthermore, even in the control school comparison samples made up of formal lower secondary schools, about 25 per cent of children leave school between Grades 7 and 9. The authors’ analysis includes propensity score matching (PSM) methods that make more focused comparisons between students in alternative programmes and control samples. These results show that dropout rates in alternative programmes are not much different than in control schools, and only significant in one programme comparison, when taking into account family background characteristics like socioeconomic status (SES). Multivariate analysis within alternative programme samples finds that attrition is lower in those learning centres which have adopted key features of formal schools, such as university-educated teachers. The results highlight the tremendous variation in the alternative middle school sector in terms of programme features, school quality and student outcomes, as well as the challenges of expanding this sector to meet the growing demand for lower secondary schooling in Honduras.  相似文献   

Using expectations and satisfaction to measure the frontiers of efficiency in public universities     

Mainardes  Emerson  Alves  Helena  Raposo  Mario 《Tertiary Education and Management》2014,20(4):339-353

Students’ satisfaction with their university and course is of fundamental importance to retain students and promote their positive worth-of-mouth. The objective of this research is to analyse the level of efficiency of Portuguese public universities, according to the expectations and satisfaction of their students. To accomplish the objective, this article uses data envelopment analysis methodology. As our unit of analysis, we selected the faculties making up the universities researched. The analytical input came from the expectations of 1669 students regarding their study programme and their universities. The outputs stem from their satisfaction with their study programmes and their universities. We conclude that university practices do not currently guarantee efficiency. We also observe that efficiency in the relationship between expectations and general satisfaction with the study programme does not represent efficiency in the relationship between expectations and general satisfaction with the university, and vice versa.  相似文献   

Unusually difficult clinical presentation of an infant suffering from congenital cytomegalovirus (CMV) infection combined with alpha 1-antitrypsin (A1AT) deficiency     

Ines Poto?njak  Goran Te?ovi?  Andrea Te?ija Kuna  Mario ?tefanovi?  Orjena ?aja 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2014,24(3):396-402

Congenital Cytomegalovirus (CMV) infection and alpha 1-antitrypsin (A1AT) deficiency are separately well described entities, but their simultaneous occurrence can pose a special challenge to a clinician, especially dealing with optimal diagnostic as well as therapeutic approach. Congenital CMV infection is the most common vertically transmitted infection in developed countries. In 85–95% of newborns it runs asymptomatic, while in others it is presented with jaundice, petechias, hepatosplenomegaly and central nervous system damage. A1AT deficiency is on the other hand, the most common genetic liver disease in children, and the clinical spectrum varies from the accidentally detected increased levels of transaminases through to the severe infant cholestasis that can progress to cirrhosis. The following case report describes a two-month old male with severe clinical presentation of congenital CMV infection probably exacerbated due to A1AT deficiency comorbidity. The clinical manifestations and unusually difficult clinical signs this infant presented lead to assumption that the additional liver damage exists. Extensive laboratory analyses were performed, including PCR for CMV DNA, A1AT serum concentration, A1AT genotyping, followed and confirmed with phenotyping. Patient was treated parenteral with ganciclovir, what continued with oral valganciclovir and supportive therapy. Intensive and thorough supportive treatment of the infant resulted in satisfactory progress and excellent outcome. Patient was followed-up till the age of 18 months. The presented case provides excellent example about successful overcoming obstacles in differential diagnosis of A1AT in neonates and infants. Medical charts analysis was the methodology used in making this report.  相似文献   

Conceptual change and anomalous data: A case study in the domain of natural sciences     

Margarita Limón  Mario Carretero 《European Journal of Psychology of Education - EJPE》1997,12(2):213-230

Cognitive conflict has been proposed as a strategy to promote conceptual change. The history and philosophy of science have shown the importance of anomalous data to change scientific theories and to the progress of science. Often, scientists use anomalous data to develop new interpretations that lead to new conceptualizations and finally, to a deep conceptual change. To be aware of contradiction seems to be a first step in the process of conceptual change. A study to explore novice students responses to anomalous data has been carried out. Sixty nine ninth graders, fifty seven eleventh graders and sixty three twelfth graders participated in the study. A paper and pencil task about the origin of life on the Earth was designed. Subjects were divided into two conditions. In condition “A” only anomalous data were presented to the subjects. In condition “A+B”, both anomalous and confirmatory data were presented. Results indicated that younger students were less aware of contradiction than older students when both anomalous and confirmatory data were presented. However, no differences have been found among them when just anomalous data were presented (condition A). Twelfth graders were aware of contradiction in both conditions. Some students’ epistemological beliefs influenced their response to anomalous data. Although no conceptual change (weak or strong restructuring) was achieved, as it could be predicted by the low domain-specific knowledge of the subjects and the complexity of the topic, presenting anomalous data facilitated the achievement of the first steps of the conceptual change process.  相似文献   

The incompatibility of science and religion sustained: A reply to our critics     

Martin Mahner  Mario Bunge 《Science & Education》1996,5(2):189-199

This article replies to a number of criticisms levelled at us by Tom Settle, Hugh Lacey, Michael Poole, Brian Woolnough, John Wren-Lewis, and Harold Turner in a series of comments on our paper entitled ‘Is religious education compatible with science education?’ By offering counter-arguments and by clarifying certain misunderstandings, we show that these criticisms fail to affect our position.  相似文献   

Students' preconceptions of the nature of gases     

Darryl L. Benson  Merlin C. Wittrock  Mario E. Baur 《科学教学研究杂志》1993,30(6):587-597

A total of 1098 students, from second graders to university chemistry students, drew representations of highly magnified views of air at 1.0 atmosphere of pressure and at 0.5 atmosphere of pressure. The drawings were classified and the authors inferred from them a relatively limited number of preconceptions of the nature of gases. Several major trends occurred in the frequencies of these inferred preconceptions held at different grade levels. The majority of the drawings that were not in fairly close agreement with atomic theory seemed to reflect one or more of the following misconceptions: (a) air is a continuous (nonparticulate) substance, (b) gas behavior is similar to liquid behavior, and (c) there is relatively little space between gas particles. The number of drawings that gave evidence of particulate views ranged from 8% for Grades 2–4 to 85% for university chemistry students. However, 33% of the university students' drawings showed highly packed particles, and only 37% showed particles in an approximately correct geometrical distribution. The authors suggest a technique for promoting conceptual change among students who possess alternative views of the nature of gases.  相似文献
