Microclimate monitoring by multivariate statistical control: The renaissance frescoes of the Cathedral of Valencia (Spain)     

Fernando-Juan García-Diego  Manuel Zarzo 《Journal of Cultural Heritage》2010,11(3):339-344

The renaissance frescoes of the metropolitan cathedral of Valencia, located at the vault of the apse, were restored in 2006. We describe a microclimate monitoring system that was implemented for the preventive conservation of the paintings. It is comprised by a set of temperature and relative humidity sensors positioned at different points of the vault. This system is rather unique because some of these sensors were inserted inside the paintings during the restoration process. A principal components analysis was applied to the data of relative humidity recorded in February 2007. The analysis was repeated in three additional months of 2007. The resulting loading plots highlight the most relevant similarities and dissimilarities among sensors. These plots can be considered as some sort of control maps that could be used to detect abnormal conditions in the future. Actually, moisture problems at certain zones of the frescoes are causing the formation of efflorescence, and the sensors located close to these zones are the ones recording the highest values of relative humidity.  相似文献

Hypothalamic–Pituitary–Adrenal and Sympathetic Nervous System Activity and Children's Behavioral Regulation     

Jared A. Lisonbee  Patricia Pendry  Jacquelyn Mize  Eugenia Parrett Gwynn 《Mind, Brain, and Education》2010,4(4):171-181

Self-regulation ability is an important component of children's academic success. Physiological reactivity may relate to brain activity governing attention and behavioral regulation. Saliva samples collected from 186 preschool children (101 boys, mean age = 53 months, 34% minority) before and after a series of mildly challenging games and again 30 min following the challenges were used to assess hypothalamic–pituitary–adrenal (HPA) (cortisol) and sympathetic nervous system (SNS; alpha-amylase) activity. Behavioral regulation was measured in delay of gratification and slow-down motor activities included in the challenge task. Cortisol and alpha-amylase were related differentially to aspects of behavioral regulation. Low cortisol was related to classroom regulation difficulties. Children with greater cortisol elevations following the challenge task had poorer performance on the slow-down motor task. Children with greater increases in salivary alpha-amylase following challenge were less able to delay gratification. Results suggest that HPA axis and SNS arousal may contribute differentially to behavioral regulation ability.  相似文献

Empirical Research on Ethnic Minority Students: 1995–2009     

Eleazar Vasquez III  Angel Lopez  Carrie Straub  Selma Powell  Tracy McKinney  Zachary Walker  Tiphanie Gonzalez  Timothy A. Slocum  Lee Mason  Breda V. Okeeffe  Peña L. Bedesem 《Learning disabilities research & practice》2011,26(2):84-93

Ethnic minority disproportionality has been a topic of extensive discussion and research for many years. In 1997, Artiles, Trent, and Kuan conducted a seminal review of the special education research literature to identify how often researchers report and disaggregate data in ways that would support conclusions about specific ethnic minority groups. These authors found alarmingly low rates of publication on identifiable minority groups. The purpose of this review is to replicate the work of Artiles et al. and extend this literature analysis to the subsequent 15‐year period (1995–2009). We found increases in the proportion of articles reporting ethnic minority information 15 years following the Artiles et al. publication. Discussion focuses on the gap in our knowledge of evidence‐based practices for ethnic minority students in special education.  相似文献   

Outside the library: Early career researchers and use of alternative information sources in pandemic times

Presents findings from a study into the attitudes and practices of pandemic-era early career researchers (ECRs) in regard to obtaining access to the formally published scholarly literature, which focused on alternative providers, notably ResearchGate and Sci-Hub. The study is a part of the Harbingers project that has been exploring the work lives and scholarly communication practices of ECRs in pre-pandemic times and during the pandemic, and utilizes data from two rounds of interviews with around 170 ECRs from the sciences and social sciences in eight countries. Findings show that alternative providers, as represented by ResearchGate and Sci-Hub, have become established and appear to be gaining ground. However, there are considerable country- and discipline-associated differences. ECRs' country-specific level of usage of the alternative providers is partly traceable to the adequacy of library provisions, although there are other factors at play in shaping ECRs' attitudes and practices, most notably convenience and time saving, as well as the fact that these platforms have become embedded in the scholarly dashboard. There is a dearth of evidence of the impact of the pandemic on ECRs' ways of obtaining scholarly papers.  相似文献   

The influence of the family,the school,and the group on the environmental attitudes of European students     

Rosa Duarte  María-Victoria Sanagustín 《Environmental Education Research》2017,23(1):23-42

The attitudes of young people arise from an intense interaction with their social groups of reference, and in this work we examine the extent to which this background conditions the individual environmental attitudes of the young. Using data provided by the PISA 2006 survey for the European Union, we test for the influence of the family, the characteristics of the school, and the social interactions or school peer group on attitudes toward the environment. The existence of social interactions, as well as the important role of family characteristics and school activities, are confirmed. The results allow us to emphasize the importance of the social context of the adolescent, and the need to take this into account as a channel that amplifies the influence of specific environmental education strategies.  相似文献   

Regenerative Capacities: New Materialisms,Inheritance, and Biopolitical Technologies in Education Policy     

Ezekiel J. Dixon-Román 《Equity & Excellence in Education》2017,50(4):434-445

Inheritance and social reproduction have been widely theorized and studied concepts in the social sciences. In theories of social reproduction a focus on social position and identity is assumed; a focus on moving from one position to another at the cost of overlooking the rich, and arguably more important, movement, process, and flow in between. Turning toward new materialisms for theoretical insight, this article points toward an alternative post-humanist perspective. Leaning on Massumi (2002) and Puar (2007), the author asserts that expanding the analytical focus to include the movement and process of biopolitical capacity will further sharpen the (new) materialist analysis of force and power relations, what Puar refers to as regenerative capacities. It is through the employment and performative force of biopolitical technologies in education policy, the author concludes, that enables the surveilling, managing, and demarcating of regenerative capacities that constrain the movement, process, and potentialities for, and of, social change.  相似文献
