Virtual microscopy (VM) is a widely used teaching method in Medical Education in many developed countries. In Brazil, however, this is not the case for most medical schools, considering Brazilian social inequality and uneven access to technology. Recently, the Covid-19 pandemic has also challenged Universities to seek and make a transition toward more effective methods of full-time online education. Thus, the main goal of this work was to verify student's perception and academic performance, assessed upon VM implementation in a Brazilian Medical School. Ribeirao Preto Medical School students answered a 26-question survey with regards to optical microscopy (OM) and VM. Academic performance was compared between participants that were (year of 2019) or were not (year of 2015) exposed to VM. Taken the results together, subjective impressions such as handling, suitability, learning effectiveness, and pleasure using the tools, have shown a higher score for virtual microscopy (median = 29), when compared to optical microscopy (median = 24) with a P-value < 0.001 by Wilcoxon rank test, upon measurement using an ordinal scale. Regarding academic performance, no statistically significant differences were found between groups (P-value = 0.38, Cohen's d = 0.19). Therefore, VM proved to be adequate to the Brazilian medical education in light of Brazilian social contexts and Covid-19 pandemic.  相似文献   

From power‐machines to intelligent‐machines: A new education for a new technological era     

Mariana Belis 《International Journal of Science Education》2013,35(3):393-397

The technological revolution of our epoch is based upon a new kind of tool, the development and use of which requires not physical strength but higher education. The computer and its many industrial applications have completely changed technology, opening up new vistas for the participation of women in the labour force. An important problem raised by these changes is the technical education of both sexes. This paper discusses the experience acquired in Romania in this respect and the results obtained in the last decades.  相似文献   

Metropolis revisited: the evolving role of librarians in informatics education for the health professions     

Samuel B. King  Mariana Lapidus 《Journal of the Medical Library Association》2015,103(1):14-18

Objective:

The authors'' goal was to assess changes in the role of librarians in informatics education from 2004 to 2013. This is a follow-up to “Metropolis Redux: The Unique Importance of Library Skills in Informatics,” a 2004 survey of informatics programs.

Methods:

An electronic survey was conducted in January 2013 and sent to librarians via the MEDLIB-L email discussion list, the library section of the American Association of Colleges of Pharmacy, the Medical Informatics Section of the Medical Library Association, the Information Technology Interest Group of the Association of College and Research Libraries/New England Region, and various library directors across the country.

Results:

Librarians from fifty-five institutions responded to the survey. Of these respondents, thirty-four included librarians in nonlibrary aspects of informatics training. Fifteen institutions have librarians participating in leadership positions in their informatics programs. Compared to the earlier survey, the role of librarians has evolved.

Conclusions:

Librarians possess skills that enable them to participate in informatics programs beyond a narrow library focus. Librarians currently perform significant leadership roles in informatics education. There are opportunities for librarian interdisciplinary collaboration in informatics programs.

Implications:

Informatics is much more than the study of technology. The information skills that librarians bring to the table enrich and broaden the study of informatics in addition to adding value to the library profession itself.  相似文献   

Business Giving,the Tsunami and Corporates as Rock Stars: Some Implications for Arts Funding?     

Jenny Harrow  Paul Palmer  Mariana Bogdanova 《Cultural Trends》2006,15(4):299-323

Financial and cultural aspects of corporate giving by UK and non-UK companies in response to the December 2004 South Asia Tsunami disaster are explored in this article. Literatures on corporate giving rationales, concepts of disaster and donor activity in disasters provide an underpinning. The article seeks to make connections between this high profile if short-lived business giving and the funding of the arts that is sought from business; and to draw tentative lessons for arts funding when seeking business support. The giving accounts in the wake of the Tsunami from a non-probability sample1 1. A probability sample is one in which each person (or company in this case) in the population has an equal chance (probability) of being selected. In a non-probability sample some people (in this case, companies) have a greater chance than others of being selected. For this study the availability of public information on the companies was the deciding factor on being selected. View all notes of 56 UK companies and 16 non-UK companies were examined. Reported online to the UK charity Business in the Community, these accounts were accessed in February 2005 and scrutinized thematically. Concurrently, company financial profiles to accompany giving figures were constructed. Although linkages between donation levels and financial performance were lacking, emerging themes included the role of employees, influencing company giving and creating a climate of expectation of firms' contributions. These developments may have important implications for business funding for the arts, where leading philanthropists are prominent as individuals in the giving landscapes; but employees' collective involvement is not marked. Alternatively, cultivation of employees as would-be donors, indirectly via their firms, may be a more secure, if lower level route to funding for some arts organizations than dependence on high profile business leaders. The article considers alternative scenarios for company giving in disaster contexts, including as a sustained and lasting giving theme or as company support as a ‘one-off’ event, rock-star style. The likely development of employee power as a key element in company giving is explored; and its wider meanings for funding in arts settings, (where the giver as rock star heroine/hero is also prominent) are considered.  相似文献   

Optimal velocity functions for car-following models   总被引：1，自引：0，他引：1  

Milan Batista  Elen Twrdy 《浙江大学学报(A卷英文版)》2010,11(7):520-529

The integral part of the optimal velocity car-following models is the optimal velocity function （OVF）, which can be derived from measured velocity-spacing data. This paper discusses several characteristics of the OVF and presents regression analysis on two classical datasets, the Lincoln and Holland tunnels, with different possible OVFs. The numerical simulation of the formation of traffic congestion is conducted with three different heuristic OVFs, demonstrating that these functions give results similar to those of the famous Bando OVF （Bando et al., 1995）. Also an alternative method is present for determining the sensitivity and model parameters based on a single car driving to a fixed barrier.  相似文献   

Verhaltens- und Kompetenzentwicklung im Kontext der Familie     

Prof. Dr. Sabine Walper  Mariana Grgic 《Zeitschrift für Erziehungswissenschaft》2013,16(3):503-531

The significance of family influences for children’s development is beyond dispute. Social disparities in stimulation provided by families and their influence on cognitive competencies have frequently been pointed out. However, little notice has been attracted to the variety of everyday family activities and their importance for children’s behavioral and competence development. Focusing on 6 to 8 years old children (n?=?1,377), this paper investigates firstly which factors affect mothers’ education-oriented and outdoor activities with their child, children’s involvement in household chores and aspects of parenting. Secondly, we analyze how these different types of activities as well as the parenting climate relate to children’s problem behavior, prosocial behavior, and everyday language skills. Cross-sectional regression analyses point to advantages of high maternal education and child-centered parenting. High maternal educational resources facilitate a focus on education-oriented activities, while outdoor activities and children’s involvement in household chores stand back. In addition to child-centered parenting, features of everyday family activities prove relevant for children’s behavioral and competence development.  相似文献   

No effect of HMB or α-HICA supplementation on training-induced changes in body composition     

Filipe J. Teixeira  Catarina N. Matias  Cristina P. Monteiro  Maria J. Valamatos  Joana F. Reis  Ana Batista 《European Journal of Sport Science》2019,19(6):802-810

β-hydroxy-β-methylbutyrate (calcium: HMB-Ca and free acid: HMB-FA) and α-hydroxyisocaproic acid (α-HICA) are leucine metabolites that have been proposed to improve body composition and strength when combined with resistance exercise training (RET). In this double-blind randomized controlled pragmatic trial, we evaluated the effects of off-the-shelf supplements: α-HICA, HMB-FA and HMB-Ca, on RET-induced changes in body composition and performance. Forty men were blocked randomized to receive α-HICA (n?=?10, fat-free mass [FFM]?=?62.0?±?7.1?kg), HMB-FA (n?=?11, FFM?=?62.7?±?10.5?kg), HMB-Ca (n?=?9, FFM?=?65.6?±?10.1?kg) or placebo (PLA; n?=?10, FFM?=?64.2?±?5.7?kg). The training protocol consisted of a whole-body resistance training routine, thrice weekly for 8 weeks. Body composition was assessed by dual-energy x-ray absorptiometry (DXA) and total body water (TBW) by whole-body bioimpedance spectroscopy (BIS), both at baseline and at the end of weeks 4 and 8. Time-dependent changes were observed for increase in trunk FFM (p?相似文献

Effect of instruction using students' prior knowledge and conceptual change strategies on science learning     

Mariana G. Hewson  Peter W. Hewson 《科学教学研究杂志》1983,20(8):731-743

One of the factors affecting students' learning in science is their existing knowledge prior to instruction. The students' prior knowledge provides an indication of the alternative conceptions as well as the scientific conceptions possessed by the students. This study is concerned primarily with students' alternative conceptions and with instructional strategies to effect the learning of scientific conceptions; i.e., to effect conceptual change from alternative to scientific conceptions. The conceptual change model used here suggests conditions under which alternative conceptions can be replaced by or differentiated into scientific conceptions and new conceptions can be integrated with existing conceptions. The instructional strategy and materials were developed for a particular student population, namely, black high school students in South Africa, using their previously identified prior knowledge (conceptions and alternative conceptions) and incorporate the principles for conceptual change. The conceptions involved were mass, volume, and density. An experimental group of students was taught these concepts using the special instructional strategy and materials. A control group was taught the same concepts using a traditional strategy and materials. Pre- and posttests were used to assess the conceptual change that occurred in the experimental and control groups. The results showed a significantly larger improvement in the acquisition of scientific conceptions as a result of the instructional strategy and materials which explicitly dealt with student alternative conceptions.  相似文献   

Lifelong learning policies supporting young adults in two Portuguese regions     

Mariana Rodrigues  Rita Queiroga  Ana Bela Ribeiro  Natália Alves  Tiago Neves 《International Journal of Lifelong Education》2020,39(1):61-74

ABSTRACT

Precarious jobs and unemployment have become common issues for many young adults due to the unfavourable labour market situation in Portugal. Against this background, lifelong learning (LLL) policies have been called in to play a role in creating economic growth and supporting the social inclusion of young adults in vulnerable educational and economic circumstances. These policies are defined at the national level; however, their implementation depends on the action of local actors who face specific challenges. This paper explores disparities in the definition and implementation of LLL policies targeting young adults in two Portuguese regions. Specifically, we analyse professional courses in Vale do Ave (North) and adult education and training courses in Alentejo Litoral (South). These regions were selected due to their dissimilar economic structure. This study adopted a qualitative approach through interviews with LLL experts and policy roundtables with local stakeholders and decision-makers in both regions. Data were transcribed and analysed using NVivo 10. The study shows that the two regions have different cooperation networks between local stakeholders, and that these impact the opportunities to influence the regional skills formation system differently. Also, the study shows that LLL policies are not designed to address destandardised life courses.  相似文献
