Piperno, a Late Quaternary magmatic rock cropping out on the eastern side of the Campi Flegrei (Italy), is probably the most important building stone of Naples, used over a time-span from at least the Roman age until the beginning of the 20th century. Despite its wide diffusion in the monumental architecture of Naples, very little is known about this rock, as regards its technical features, as well as the geological aspects. This paper aims at providing a first overall contribution towards a rediscovery of this long-time-used material, in view of careful restoration works, which nowadays at Naples only take into account the proper geological features of the stone in a few peculiar cases. Thus, it seems of extreme importance to understand the basic parameters of Piperno and, above all, its response to weathering agents. Main mineralogical, petrographical and engineering–geological properties are presented here for the first time, with specific reference to two sampling areas, located at Pianura and Soccavo, in the western sector of the Neapolitan urban area. As far as many of its physico–mechanical features are concerned, Piperno extends over a wide range of values, which allow different varieties of the rock to be identified. This preliminary result is seemingly in accordance with data from old historical literature, which stated the existence of six horizons in the Piperno formation.  相似文献   

Is season of birth related to developmental dyslexia?

Different moderators/mediators of risk are involved in developmental dyslexia (DD), but data are inconsistent. We explored the prevalence of season of birth and its association with gender and age of school entry in an Italian sample of dyslexic children compared to an Italian normal control group. The clinical sample included 498 children (345 boys, mean age 10.3 ± 2.1 years) with DD, the control sample 1,276 children (658 boys, mean age 10.8 ± 2.2 years) from four elementary schools from the same urban area, and with the same socio-economic status level. A prevalence of birth in autumn was found among children with DD compared to controls (34% versus 24%, p < 0.0001). Children with DD were more frequently males (p < 0.0001) and had a lower mean age of school entry (p < 0.0001). Regarding the distribution of ages, 11.4% of children with DD, but none of the subjects in the control group, started school before 5.7 years. Therefore, greater risk of DD was related to age of school entry (OR = 2.72), gender (OR = 2.16), and season of birth (OR = 1.21). Significant interactions between boys with DD born in autumn, and correct school of entry (OR = 2.56) were joint predictors of higher risk of DD. The association between birth in autumn and DD may be explained by the earlier age of school entry, which may be a critical element in the youngest children with DD or at risk to DD. Whether Italian school policy is oriented to anticipate the school entry, a closer detection of early learning disorders and associated risk factors (familial load, specific language disorders, and attention deficit hyperactivity disorder) should be warranted.  相似文献

Effectiveness of bibliographic searches performed by paediatric residents and interns assisted by librarians. A randomised controlled trial     

Gardois P  Calabrese R  Colombi N  Deplano A  Lingua C  Longo F  Villanacci MC  Miniero R  Piga A 《Health information and libraries journal》2011,28(4):273-284

Background: Considerable barriers still prevent paediatricians from successfully using information retrieval technology. Objectives: To verify whether the assistance of biomedical librarians significantly improves the outcomes of searches performed by paediatricians in biomedical databases using real‐life clinical scenarios. Methods: In a controlled trial at a paediatric teaching hospital, nine residents and interns were randomly allocated to an assisted search group and nine to a non‐assisted (control) group. Each participant searched Pub Med and other online sources, performing pre‐determined tasks including the formulation of a clinical question, retrieval and selection of bibliographic records. In the assisted group, participants were supported by a librarian with ≥5 years of experience. The primary outcome was the success of search sessions, scored against a specific assessment tool. Results: The median score of the assisted group was 73.6 points interquartile range (IQR = 13.4) vs. 50.4 (IQR = 17.1) of the control group. The difference between median values in the results was 23.2 points (95% CI 4.8–33.2), in favour of the assisted group (P‐value, Mann–Whitney U test: 0.013). Conclusions: The study has found quantitative evidence of a significant difference in search performance between paediatric residents or interns assisted by a librarian and those searching the literature alone.  相似文献   

Promotion of autonomy for participation in physical activity: a study based on the trans-contextual model of motivation     

David González-Cutre  Roberto Ferriz  Vicente J. Beltrán-Carrillo  José A. Andrés-Fabra  Carlos Montero-Carretero  Eduardo Cervelló 《教育心理学》2014,34(3):367-384

The aim of this study was to analyse the effects of a school-based intervention to promote physical activity, utilising the postulates of the trans-contextual model of motivation. The study examined two separate classes of elementary school students (mean age 11.28?years), one of which served as the control group (n?=?26) and the other as the experimental group (n?=?21). The intervention in the experimental group consisted of showing videos related to physical activity participation, conducting discussions and doing tasks related to the content presented in the videos and conducting family discussions. Autonomy support from teachers, peers and parents; motivation in physical education and leisure time physical activity; the different variables of theory of planned behaviour; and physical activity, were measured before and after the intervention. Results showed an increase in teacher autonomy support, identified regulation in physical education, autonomy support from parents and peers, integrated and identified regulation in leisure time physical activity, control, subjective norm, intention and physical activity in the experimental group. Furthermore, this increase resulted in post-intervention differences across groups in such variables. Results are discussed in relation to the important role of families in the promotion of physical activity participation.  相似文献   

“If There is No Struggle, There is No Progress”: Transformative Youth Activism and the School of Ethnic Studies     

Nolan L. Cabrera  Elisa L. Meza  Andrea J. Romero  Roberto Cintli Rodríguez 《The Urban Review》2013,45(1):7-22

In the wake of the Tucson Unified School District dismantling its highly successful Mexican American Studies (MAS) program, students staged walkouts across the district to demonstrate their opposition. Student-led walkouts were portrayed as merely “ditching,” and students were described as not really understanding why they were protesting. After these events, a group of student activists called UNIDOS organized and led the School of Ethnic Studies. This was a community school dedicated to teaching the forbidden MAS curriculum. In this article we present counternarratives from organizers, presenters, and participants in the School of Ethnic Studies. These narratives demonstrate the transformative resistance of students who created their own form of liberatory education. Our analysis highlights how student organizers led the creation of an autonomous, community-based educational space to allowed young people to engage in political analysis, self-reflection, and strategic organizing. We conclude with the implications for Ethnic Studies, urban education, and counternarrative.  相似文献

Abstract

This study aimed to evaluate the autonomic modulation of heart rate in sedentary paraplegics and paraplegic wheelchair basketball players with thoracic spinal cord injury below T6. Seven paraplegic wheelchair basketball players (active paraplegic group), five paraplegics who were not involved in regular exercise (sedentary paraplegic group) and 10 able-bodied participants (control group) took part in the study. The heart rate variability was evaluated by linear (low frequency and high frequency band in normalised units and low frequency/high frequency ratio) and nonlinear methods (Shannon entropy, corrected conditional entropy, and symbolic analysis).

The sedentary group presented significantly higher values for low frequency, low frequency/high frequency ratio and symbolic index with no significant variations (0V%), and also lower values for the high frequency and symbolic index with two significant unlike variation (2ULV%) compared to active paraplegic group. Shannon entropy and corrected conditional entropy analyses revealed significantly lower values in the sedentary group than in the control or active paraplegic groups. Paraplegic individuals who regularly undertake physical exercise have higher complexity of R-R interval time series, lower sympathetic modulation, and higher parasympathetic modulation than sedentary paraplegic participants.  相似文献   

Institutional Quality of a Higher Education Institution from the Perspective of Employers     

Karmen Rodman  Roberto Biloslavo  Silva Bratož 《Minerva》2013,51(1):71-92

The present paper proposes a theoretical model of institutional quality of a higher education institution (HEI) which, in addition to the internal dimensions of quality, incorporates also the external dimension, i.e. the outcomes dimension. This dimension has been neglected by the quality standards and models examined in our paper. Furthermore, the standards and models analyzed consider stakeholders as one of the quality factors of a HEI. The stakeholders’ perspective is seen as a lens through which stakeholders define, control and assess the quality of a HEI. The proposed model therefore gives stakeholders greater significance compared to the dimensions of institutional quality of a HEI. The model has been validated from the employers’ perspective. On the basis of 339 completed questionnaires or a 39.74 % response rate we concluded that outcomes constitute the most important dimension of institutional quality of a HEI from the perspective of employers in Slovenia. The outcomes dimension is followed, in descending order, by the non-financial resources and inputs, sustainable development, value chain, and, finally, the financial resources and inputs dimensions. The results of the study have shown that of the 44 quality factors of a HEI the following data are of key importance to employers: information on the participation of students in practical training, achievements of graduates at the workplace, implementation of a HEI’s research achievements in practice, graduate employability, and a HEI’s responsiveness to the demands and changes in the environment.  相似文献
