Feeling Brown in the Academy: Decolonizing Mentoring Through a Disidentification Muxerista Approach     

Jeannette D. Alarcón  Silvia Bettez 《Equity & Excellence in Education》2017,50(1):25-40

According to the Chronicle of Higher Education, “Hispanics” comprise only 4% of the full-time faculty in U.S. universities, although Latin@s comprise 16.4% of the U.S. population. Given the under-representation of Latin@ faculty, efforts to support and retain them are paramount. Recently a small body of literature has surfaced explicitly centering the practices of peer mentoring among Latin@s. Through collaborative auto-ethnography and counter-storytelling, using a framework of disidentification, muxerista mentoring, and community cultural wealth, we add to this literature by discussing our experience of engaging in non-hierarchical Latina peer mentoring at a predominantly White university. The main themes include: merging emotional needs with professional growth, forging learning and research partnerships, Browning teaching spaces and transforming institutional practices.  相似文献   

Do sophisticated epistemic beliefs predict meaningful learning? Findings from a structural equation model of undergraduate biology learning     

Silvia Wen-Yu Lee  Chin-Chung Tsai 《International Journal of Science Education》2016,38(15):2327-2345

This study investigated the relationships among college students’ epistemic beliefs in biology (EBB), conceptions of learning biology (COLB), and strategies of learning biology (SLB). EBB includes four dimensions, namely ‘multiple-source,’ ‘uncertainty,’ ‘development,’ and ‘justification.’ COLB is further divided into ‘constructivist’ and ‘reproductive’ conceptions, while SLB represents deep strategies and surface learning strategies. Questionnaire responses were gathered from 303 college students. The results of the confirmatory factor analysis and structural equation modelling showed acceptable model fits. Mediation testing further revealed two paths with complete mediation. In sum, students’ epistemic beliefs of ‘uncertainty’ and ‘justification’ in biology were statistically significant in explaining the constructivist and reproductive COLB, respectively; and ‘uncertainty’ was statistically significant in explaining the deep SLB as well. The results of mediation testing further revealed that ‘uncertainty’ predicted surface strategies through the mediation of ‘reproductive’ conceptions; and the relationship between ‘justification’ and deep strategies was mediated by ‘constructivist’ COLB. This study provides evidence for the essential roles some epistemic beliefs play in predicting students’ learning.  相似文献   

Usefulness of serum CA 15.3 and histopathological prognostic indices in breast cancer     

R. Nalini  C. R. Wilma Delphine Silvia  Purnima M. Makhija  Sheila Uthappa 《Indian journal of clinical biochemistry : IJCB》2005,20(1):165-168

Prognostic factors influence the modality and course of therapy in breast cancer. These include both histopathological and biochemical variables. This study was aimed to find out if any correlation exists between the biochemical tumor marker-serum CA 15.3, and the lymph node staging of Nottingham’s Prognostic Index (NPI). It was observed that serum CA 15.3 showed a statistically significant correlation with lymph node staging of NPI. Therefore it is concluded that CA 15.3 can be utilized as a useful prognostic marker, particularly in cases where histopathological variables such as tumor size and grade have been altered by pre-operative chemotherapy.  相似文献   

Hi-bye friends and the herd instinct: international and home students in the creative arts   总被引：1，自引：0，他引：1  

Silvia Sovic 《Higher Education》2009,58(6):747-761

The crucial role of social integration for the academic success of home students is a common theme in pedagogical research, but for international students the emphasis has been much more on cultural factors and the challenges of transition. The findings of the International Students’ Experience Project at the University of the Arts, London suggest that this is far from the whole story. International students come to the UK precisely to make cosmopolitan friendships, but are held back—by language and communication, but also, less obviously, by differences in age, qualifications, experience and expectations, and by the need to adapt rapidly to an environment which is new in every sense. While home students surmount the challenges of social integration with relative ease, international students thus need more support. By coming to understand the needs of these students in all their complexity, institutions can play a key role in facilitating integration.  相似文献   

The international epidemiology of child sexual abuse: A continuation of Finkelhor (1994)     

Noemí Pereda  Georgina Guilera  Maria Forns  Juana Gómez-Benito 《Child abuse & neglect》2009,33(6):331-342

ObjectiveThe purpose of this paper was to compare the prevalence rates of child sexual abuse reported by [Finkelhor, D. (1994). The international epidemiology of child sexual abuse. Child Abuse & Neglect, 18 (5), 409–417] with those found in recent publications in order to confirm the widespread prevalence of child sexual abuse.MethodsRelevant articles about prevalence of child sexual abuse were identified through searches of computerized databases and a handsearch of Child Abuse & Neglect and the Journal of Child Sexual Abuse.ResultsThirty-eight independent articles were identified, corresponding to 39 prevalence studies; these articles report the prevalence of childhood sexual abuse in 21 different countries, ranging from 0 to 53% for women and 0 to 60% for men.ConclusionsComparison of the present study with that of [Finkelhor, D. (1994). The international epidemiology of child sexual abuse. Child Abuse & Neglect, 18 (5), 409–417] shows a similarity between prevalence distributions; there appears to be a general pattern that remains more or less constant over the years, especially in women.Practice implicationsTwelve years after the first revision study about the international prevalence of child sexual abuse, there is still a need for new data about this topic. The present study shows child sexual abuse is still a widespread problem in the society. In this research, carried out on 38 independent studies, there is new data for 21 countries over the world, being especially relevant the results obtained from other countries different from those pertaining to North America or Europe. It is important to point out the high prevalence found in most of the countries, so this information could be a new warning to make society and governments aware of this problem and undertake actions to prevent sexual abuse in childhood.  相似文献   

Thinking aloud together: A teacher’s semiotic mediation of a whole-class conversation about percents     

Sam Shreyar  Betina Zolkower  Silvia Pérez 《Educational Studies in Mathematics》2010,73(1):21-53

How does classroom interaction support students’ apprenticeship into the ways of speaking, writing, and diagramming that constitute the practice of mathematics? We address this problem through an interpretative analysis of a whole-group conversation about alternative ways of solving a problem involving percent discounts that occurred in a sixth grade classroom. This research study draws upon Dewey’s theory of inquiry, Vygotsky’s cultural–historical psychology, Freudenthal’s realistic mathematics education, and Halliday’s systemic functional linguistics (SFL). From Freudenthal, we borrow the notions of mathematizing and guided reinvention—the former notion offers a view of mathematics as an activity of structuring subject matter and the latter one provides insights into the processes whereby mathematizing is learned and taught in the classroom. We glean from Dewey his view of reflective thinking as inquiry and the role that conversations may serve therein. We rely upon Vygotsky’s notions of a verbal thinking plane and a social phase of learning in order to reconsider the function of whole-class interaction in apprenticing students into mathematizing. Finally, SFL provides us with tools for explaining the choices of grammar and vocabulary students and teachers make as they realize meanings in whole-group conversations. Treating the selected whole-class conversation as a text, we focus our analysis on how this text came to mean what it did. Our central questions are as follows: What meanings were realized in the whole-class conversation by teacher and students and how were these meanings realized? How did the teacher’s lexico-grammatical choices guide the students’ choices? In addressing these questions, we advance an interpretation of the conversation as paradigmatic of students and teacher thinking aloud together about percents.  相似文献   

Evaluation use and involvement of internal stakeholders: The case of a new non-degree online program in Brazil     

Edgard B. Cornachione  Maria R. Trombetta  Silvia P.C. Casa Nova 《Studies in Educational Evaluation》2010,36(1-2):69-81

To what extent does the intense and direct involvement of internal stakeholders, such as program managers and staff members, play a significant role toward evaluation use? Stakeholder involvement is a key element in evaluation and evaluation use is considered within a broader sense that includes organizational knowledge, individual skills, and immediate program reviews. The background of this new non-degree online program is directly related to the Brazilian socioeconomic, cultural, and educational framework. Conclusions include 12 major claims related to program evaluation and an integrative approach involving Patton's and Stake's evaluation theories. Although delimited by the natural boundaries of a case study design, conclusions may benefit the strategic discussion of program evaluation in similar situations, at both professional and academic levels.  相似文献   

Numbers and Space Intervals in Length Measurements in the Spanish Context: Proposals for the Transition to Measuring with the Ruler     

Ariadna Gómezescobar  Raquel Fernández-Cézar  Silvia Guerrero 《International Journal of Science and Mathematics Education》2018,16(7):1375-1386

The present work shows how 4–6-year-old Spanish children interpret numbers and space intervals in the ruler when measuring length. To determine it, 4 ad hoc rulers are designed and used with a sample of 103 children from two schools of Toledo province (Spain). The sample is characterized respecting conservation and measurement with the standard ruler confirming that these children mostly neither conserve nor use the standard ruler correctly, regardless their time exposure to instruction. With the use of our rulers, we confirm that numbers hinder in measuring length, and discrete units imbedded in the ruler help children to measure correctly. A good scaffold is found to help children conceptualize space intervals as iterating objects consisting on the use of rulers with discrete units on them. Its use is recommended preceding the one of standard rulers.  相似文献   

Different types of compression clothing do not increase sub-maximal and maximal endurance performance in well-trained athletes

Abstract

Three textiles with increasing compressive surface were compared with non-compressive conventional clothing on physiological and perceptual variables during sub-maximal and maximal running. Fifteen well-trained endurance athletes (mean ± s: age 27.1 ± 4.8 years, [Vdot]O_2max 63.7 ± 4.9 ml · min^?1 · kg^?1) performed four sub-maximal (～70%[Vdot]O_2max) and maximal tests with and without different compression stockings, tights, and whole-body compression suits. Arterial lactate concentration, oxygen saturation and partial pressure, pH, oxygen uptake, and ratings of muscle soreness were recorded before, during, and after all tests. In addition, we assessed time to exhaustion. Sub-maximal (P = 0.22) and maximal oxygen uptake (P = 0.26), arterial lactate concentration (P = 0.16; 0.20), pH (P = 0.23; 0.46), oxygen saturation (P = 0.13; 0.26), and oxygen partial pressure (P = 0.09; 0.20) did not differ between the types of clothing (effect sizes = 0.00–0.45). Ratings of perceived exertion (P = 0.10; 0.15), muscle soreness (P = 0.09; 0.10) and time to exhaustion (P = 0.16) were also unaffected by the different clothing (effect sizes = 0.28–0.85). This was the first study to evaluate the effect on endurance performance of different types of compression clothing with increasing amounts of compressive surface. Overall, there were no performance benefits when using the compression garments.  相似文献   

Personal ontologies: Generation of user profiles based on the YAGO ontology     

Silvia Calegari  Gabriella Pasi 《Information processing & management》2013

Personalized search is aimed at tailoring the search outcome to users; to this aim user profiles play an important role: the more faithfully a user profile represents the user interests and preferences, the higher is the probability to improve the search process.  相似文献
