A Simple Laboratory Exercise for Ethanol Production by Immobilized Bakery Yeasts (Saccharomyces cerevisiae)     

Diana L. Vullo  Mónica B. Wachsman 《Journal of Food Science Education》2005,4(3):53-55

ABSTRACT: This laboratory experiment was designed for Chemistry, Food Technology, Biology, and Chemical Engineering undergraduate students. This laboratory experience shows the advantages of immobilized bakery yeasts in ethanol production by alcoholic fermentation. The students were able to compare the ethanol production yields by free or calcium alginate entrapped cells and appreciated the easy separation of the final product and the biocatalyst reutilization.  相似文献   

Wallowing in Media Past: Media-Induced Nostalgia’s Connection to Parasocial Relationships     

Tim Wulf  Diana Rieger 《Communication Research Reports》2018,35(2):178-182

This article elaborates on media-induced nostalgia as a mixed emotion elicited by remembering past media content and characters. It argues that social components of media consumption such as parasocial relationships (PSRs) play an important part in the elicitation of nostalgia. In an online study, participants (N = 96) remembered their individual media use and preferred media characters as children. Results show that media-induced nostalgia is significantly associated with PSRs to characters in the past. These findings are evaluated concerning their implications for future research on nostalgia and PSRs.  相似文献   

Partnering with the Public Library for Health Care Education: An Evaluation of Affordable Care Act Messages     

Daniela B. Friedman  Vance Kornegay  Andrea Tanner  Diana C. Sisson  Megan A. Weis 《Public Library Quarterly》2016,35(1):1-22

Despite implementation of most of the provisions of the Affordable Care Act (ACA) by 2014, the public still has questions about the health care law. To assess the potential of using the library as a hub for ACA education, we tested existing and new culturally relevant messages about the health care law with twenty-seven community members. Participants discussed the message prototypes, including the visual components and promotional content, and provided advice to modify content and design to best reach target audiences. Future research can follow this example to engage libraries and community members in developing and evaluating culturally relevant health messages.  相似文献

Perceptions of Portuguese undergraduate students about assessment: a study in five public universities     

Diana Pereira  Maria Assunção Flores  Alexandra Barros 《Educational studies》2017,43(4):442-463

This paper draws upon a broader piece of research on assessment in higher education, particularly focusing on issues regarding the fairness and effectiveness of the assessment methods and their implications for the learning process. The perceptions of undergraduate students are analysed taking into account the effectiveness and fairness of both traditional and learner-centred assessment methods, as well their influence on the learning process. In total, 624 students participated in this study in five Portuguese Public Universities in different areas of knowledge and programmes. Data were collected through questionnaires. Findings suggest that assessment is seen as more effective and fairer when it is done through the use of learner-centred assessment methods rather than by traditional assessment (e.g. written tests or exams). The students also claim that they devote more time to study when assessment is performed through learner-centred assessment methods than by traditional ones. The most used assessment methods are written tests and oral presentations in group. However, differences in the programmes were identified as well as differences according to gender. Implications of the findings for assessment and for the teaching and learning process are discussed.  相似文献   

Leadership training in science,technology, engineering and mathematics education in Bulgaria     

Diana Bairaktarova  Monica F. Cox  Demetra Evangelou 《European Journal of Engineering Education》2011,36(6):585-594

This synthesis paper explores current leadership training in science, technology, engineering and mathematics (STEM) education in Bulgaria. The analysis begins with discussion of global factors influencing the implementation of leadership training in STEM education in general and then presents information about the current status of leadership training in Bulgaria with emphases on the country's economics, politics and geographical location as specific factors influencing leadership education. A short background of Bulgaria is presented with regard to population, gross domestic product, educational system, engineering force and possible need for leaders in industry in Bulgaria and the European Union. The paper provides an overall view about the current status of leadership training in all Bulgarian universities offering STEM education and concentrates specifically on two major universities by examining their currently offered programmes. As part of the discussion, similar training elements in other European countries and the USA are presented.  相似文献   

Reasons and motivations for the option of an engineering career in Portugal     

Diana Dias 《European Journal of Engineering Education》2011,36(4):367-376

Towards the end of their secondary education, students face significant pressures in their decision about their career plan. These pressures are internal and external, personal and social, individual and from the reference group. This paper aims at understanding the reasons driving engineering students’ choices, their perceived needs and aspirations. Moreover, it discusses how, in that process, students are constrained by family and friends and are conditioned by factors such as their socioeconomic and cultural background, employability prospects and gender. The construction of a career map/plan and the reasons and motivations for the option of an engineering career are reviewed, based on the qualitative analysis of students’ discourses. The data indicate the relevance of several criteria such as social status, intelligence, gender, competences, values and interests in the construction of career aspirations. All these levels are highly influenced by self-esteem, which is closely related to the social value of training options and career paths.  相似文献   

The digital literacy debate: an investigation of digital propensity and information and communication technology   总被引：1，自引：0，他引：1  

Angelique Nasah  Boaventura DaCosta  Carolyn Kinsell  Soonhwa Seok 《Educational technology research and development : ETR & D》2010,58(5):531-555

Research suggests students’ use of information and communication technology (ICT) may be more a matter of digital literacy and access rather than a generational trait. We sought to identify ICT preferences of post-secondary students (N = 580) through a Digital Propensity Index (DPI), investigating communication methods, Internet practices and the creation of online content. Age, gender and socioeconomic status were examined as factors which might explain why students use ICT. Results suggest age is a factor in ICT use but that it is not the most important consideration; the gender gap and gaps between socioeconomic groups in terms of ICT use may be closing. The findings raise a variety of implications for institutions training pre-service teachers, curriculum developers designing instructional materials and educational leaders developing ICT policy for schools.  相似文献

This work describes the genesis, articulation and consolidation from 2007 of a social network of b-learning （blended learning） in the UA （University of Alicante） （Spain）, with the institutional backing of the Office of the Vice President for Education Technology and Innovation, and the momentum and advice of professor Angel Fidalgo （UNESCO （United Nations Educational, Scientific and Cultural Organization） chair for University of Management and Policy）. The social network currently has more than 25 teachers, working on different work linkages with the university, implementing or intending to apply the teaching methodologyb-learning during the course 2007-2008 in a variety of courses and degrees. To do so, several resource centers （blogs, wikis, Wimba Create （before CourseGenie）, etc.）, and digital platforms （Virtual Campus of the UA, Moodle, etc.） are used.  相似文献
