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

Increasingly, invitro culture of adherent cell types utilizes three-dimensional (3D) scaffolds or aggregate culture strategies to mimic tissue-like, microenvironmental conditions. In parallel, new flow cytometry-based technologies are emerging to accurately analyze the composition and function of these microtissues (i.e., large particles) in a non-invasive and high-throughput way. Lacking, however, is an accessible platform that can be used to effectively sort or purify large particles based on analysis parameters. Here we describe a microfluidic-based, electromechanical approach to sort large particles. Specifically, sheath-less asymmetric curving channels were employed to separate and hydrodynamically focus particles to be analyzed and subsequently sorted. This design was developed and characterized based on wall shear stress, tortuosity of the flow path, vorticity of the fluid in the channel, sorting efficiency and enrichment ratio. The large particle sorting device was capable of purifying fluorescently labelled embryoid bodies (EBs) from unlabelled EBs with an efficiency of 87.3% ± 13.5%, and enrichment ratio of 12.2 ± 8.4 (n = 8), while preserving cell viability, differentiation potential, and long-term function. 相似文献

In a special section of the american Annals of the Deaf, Deaf education and the Deaf community in South Africa are discussed. The special section is organized into 7 segments: a historical overview to establish context, the educational context, educators and learners, postgraduate education and employment, perspectives of Deaf children and their parents, sport and the arts, and spiritual lives and mental health. Throughout the entire section, however, the central focus is on the overall foundation (or lack thereof) of education for Deaf learners in South Africa. 相似文献

Decades of research demonstrate that college students benefit from positive interaction with faculty members, although that
same evidence suggests that those interactions are far from common, particularly outside the classroom. Moreover, relatively
little is known about which, when, how, and why faculty members choose to engage with students outside of the classroom. Guided
by the theory that faculty members use in-class behaviors to signal their “psychosocial approachability” for out-of-class
interaction with students (Wilson et al. in Sociology of Education 47(1):74–92, 1974; College professors and their impact on students, 1975), this study uses data from 2,845 faculty members on 45 campuses to identify the personal, institutional, and pedagogical
factors that influence the frequency and type of interaction faculty members have with students outside of the classroom. 相似文献

Experiencing mindfulness during movement-based interventions (e.g., yoga) may help support adaptive physical activity motivation processes in youth. However, there is currently no measure for assessing state mindfulness with youth within the context of physical activity. The purpose of this study was to qualitatively and quantitatively evaluate a measure of state mindfulness for physical activity in youth. In study one, cognitive interviews with youth (N = 15) ages 8–13 evaluated the State Mindfulness Scale for Physical Activity item comprehension and preference for developmentally worded modifications. Results suggest that problems with item comprehension were more likely in youth younger than 10. In study two, the State Mindfulness Scale for Physical Activity, or a modified version, was administered randomly to middle-school students (N = 481). Internal consistency reliability, confirmatory factor analyses, model-based reliability omega, and correlations with theoretically relevant variables combined with the qualitative evidence provided stronger initial support for the use of the original State Mindfulness Scale for Physical Activity with middle-school students. 相似文献

Demographic and structural features of kindergarten classrooms are described using data from the National Center for Early Development and Learning's (NCEDL) Transition Practices Survey, a nationally representative survey of kindergarten teachers (n=3595), as a first step in investigating the context of the transition to kindergarten. Findings indicate that kindergarten teachers have a lot of education and experience, but lack specific training on facilitating transitions to kindergarten. Kindergarten classrooms generally meet National Association for the Education-of Young Children (NAEYC) (Bredekamp & Copple, 1997) guidelines for class size, but are larger than some research indicates is optimal (Mosteller, 1995). All estimates are presented for the overall population and by metropolitan status, district poverty, and minority enrollment. Few differences were found between subgroups on teacher education, experience, transition training, or class size. 相似文献
