Quality of Chilean Early Childhood Education from an International Perspective Qualité de l'Education Préscolaire Chilienne dans une Perspective Internationale Calidad de la Educacio´n Preescolar Chilena desde una Perspectiva Internacional

The aim of the study was to assess the quality of the different types of Chilean early childhood care and education programmes according to international standards. The sample included 120 centres representing the different types of pre-school programmes available, randomly selected from two different geographical regions of the country, where 52% of the population lives. This paper presents the structural and process characteristics observed in the classrooms, according to the results from the application of the Early Childhood Environment Rating Scale (ECERS). All the different types of pre-school programmes in Chile exhibited a minimum level of quality, even though there are differences among types of programmes and also according to the geographical area where they were settled. Results are compared with findings from the European Child Care and Education (ECCE) study developed in Austria, Germany, Portugal and Spain and from the Effective Provision of Pre-school Education (EPPE) project, developed in Britain. Cette étude se propose de évaluer la qualitédes différents programmes d'éducation et soin d'enfants au Chili, selon des standards internationaux. 120 centres ont été selectionnés au hasard, dans les deux départements du pays ou habite le 52% de la population.

Which difficulties and resources do vocational teachers perceive? An exploratory study setting the stage for investigating teachers’ resilience in Switzerland

ABSTRACT

Based on an ecological view of teacher resilience, the paper investigates perceived difficulties and resources among vocational education and training (VET) teachers as a first step for investigating teachers’ resilience. Given the substantial shortage of theoretical and empirical studies on this population, more research on resilience among VET teachers is necessary and relevant. In this exploratory qualitative study, interviews with VET teachers in Switzerland (n = 37) sought to identify the specific challenges faced by teachers, the resources to be addressed. As well as confirming the different critical challenges and protective factors emerging from the literature review, the results identify difficulties and resources specific to VET teachers in Switzerland. In terms of critical challenges at a macro-contextual level, teachers’ low social recognition is emphasised. Moreover, exposure to curricular reforms generates stress and pressure related to the required standardisation of content and subject changes. At a micro-system level, we detected teachers’ frustration in relation to students’ low vocational motivation and maturity and specific emerging instructional challenges in vocational subject teaching. In terms of resources, teachers perceived the possibility of diversifying their professional role by alternating school and extracurricular activities as a supportive factor. The results provide a basis for more extensive quantitative study investigating relationship among adversities and resources and resilient strategies.     

Effects of an instructional gaming characteristic on learning effectiveness,efficiency, and engagement: using a storyline for teaching basic statistical skills

The study explored instructional benefits of a storyline gaming characteristic (GC) on learning effectiveness, efficiency, and engagement with the use of an online instructional simulation for graduate students in an introductory statistics course. A storyline is a game-design element that connects scenes with the educational content. In order to examine the interactions between the storyline GC and human performance, a storyline was embedded in a simulation. The goal of the simulation was to engage students in problem-solving and data analysis in the context of basic statistics by using real-world examples. The authors developed two different versions of the simulation: (1) Simulation+No GC, and (2) Simulation+Storyline GC. Both versions shared the same instructional content but differed in the presence or absence of a storyline GC. The results indicated that adding a storyline to a simulation did not result in significant improvements in learning effectiveness, efficiency, or engagement. However, both instructional methods (simulation and simulation with a storyline) showed significant learning gains from pre- to post-test. The findings of this study offer future directions for embedding a storyline GC into learning content.     

Design procedure for thin three-layer plates made of a depleted material

The efficiency of a long-span structure relies on how material is locally distributed within a fixed structural shape. In this paper a design procedure for thin plates made of three layers of a depleted material subject to a distributed vertical load is proposed. The investigation is driven by the idea of the optimal material organization and has the objective of maximizing the overall stiffness/weight ratio of the structure. Two microstructural architectures of the media are considered: a porous solid structure and a truss arrangement. For each type of microstructure the flexural stiffness has been correlated to the level of depletion by the use of a power law function by setting very few parameters. Finally, invoking the principles of structural homogenization theory, the global flexural response of the plate has also been calculated. The validity of the method is demonstrated by comparing the analytical results with those obtained by a numerical finite element simulation of the structure based on a detailed model of the media.     

Study of the deterioration products,gilding, and polychromy of the stones of the Scuola Grande Di San Marco's façade in Venice

The Scuola Grande di San Marco is one of the most outstanding Renaissance buildings in Venice. Destroyed by fire in 1485, the Scuola was reconstructed between 1487 and 1495 by Pietro Lombardi (and sons), together with Giovanni Buora and Mauro Codussi. The façade is considered one of the finest and most original exteriors of Venetian buildings and in particular features refined sculptural and painted decorations and a remarkable pictorial effect created by the extensive use of polychrome marbles and the false perspective view between the pilasters of the lower order. Most of the stone materials (Istrian and Verona red limestones, nero di Roveré, pavonazzetto toscano, Carrara marble and various reused antique marbles) present evident decay phenomena such as scaling, exfoliation, powdering, fissuring, salt efflorescence, black crusts, and artificial patinas of various kinds. The present study reports the results of petrographic and chemical laboratory analyses carried out in preparation for the conservation treatment of the building, in order to characterize the main micro- and macro-morphologies of decay and to identify the causes and mechanisms of deterioration as well as the nature and application technique of the polychromy, gilding, and patinas present on parts of the monumental Renaissance façade.     

The logic of practice in the practice of logics: practicing journalism and its relationship with business in times of technological changes

This paper investigates the workings of institutional logics in practice, by focusing in particular on the interplay between material, practical and linguistic dimensions of practices. In other words, drawing on Bourdieu's sens pratique, the paper explores the logic of practice in the practice of logics through a six months full-time ethnographic study at Il Sole-24 Ore, the largest Italian financial newspaper, between 2007 and 2008. An original conceptual framework is developed to analyse how the logic of journalism is enacted vis-à-vis that of advertising in a setting in which an old technology for news production – print newspaper – coexists with a new one – website – and thus encounters between new and old technological possibilities make workings of institutional logics particularly visible. The findings point out different mechanisms of institutional work dealing with actions that, made possible by new technological possibilities, are potentially, but not necessarily classified as divergent from institutional logics.     

Resistance to carbonation of concrete after re-alkalization by absorption of sodium carbonate solution

The paper presents experimental research on the durability of a non-conventional technique for the repair of reinforced concrete damaged by carbonation-induced corrosion of steel reinforcement. The technique is called electrochemical re-alkalization and is often considered as an option for the repair of buildings, structures, and other artefacts made of reinforced concrete, for which conservation requirements are becoming increasingly important, in spite of their relatively young age. Absorption of a sodium carbonate solution is one of the processes that lead to concrete re-alkalization. The aim of the work is to investigate the contribution of this process to preventing future carbonation of re-alkalized concrete. Concrete specimens with six different compositions were initially carbonated, then re-alkalized through absorption of a sodium carbonate solution, and then exposed again to carbonation (re-carbonation). The results showed that the pH of concrete after re-carbonation was only slightly lower compared to that of re-alkalized concrete, highlighting a contribution of the treatment in preventing future pH reduction.     

Understanding the Etiology of Complex Traits: Symbiotic Relationships Between Psychology and Genetics

ABSTRACT— The present article offers comments on the infusion of methodologies, approaches, reasoning strategies, and findings from the fields of genetics and genomics into studies of complex human behaviors (hereafter, complex phenotypes). Specifically, I discuss issues of generality and specificity, causality, and replicability as they pertain to molecular genetic studies of human phenotypes. These issues are illustrated with findings from genetic linkage and association studies investigating the etiology of disorders of spoken and written language—an area of inquiry that has been consistently referenced as one of the most successful in terms of its progress in understanding the genetic bases of human behaviors. I complete this discussion with comments on how the stronger presence of genetics and genomics in psychology is changing the conceptualization and investigation of research questions and affecting the next generation of interdisciplinary research.     

Deterioration of building materials and artworks in the ‘Santa Maria della Stella’ church,Saluzzo (Italy): Causes of decay and possible remedies

An in-depth scientific survey revealed the deterioration mechanisms affecting the ‘Santa Maria della Stella’ church in Saluzzo, Italy, where various salt crystallization processes are strongly damaging the building materials and artworks. Rainwater seepage permeates the vault and interior, causing: (1) epsomite growth as interstitial columnar crystals (resulting in pictorial coating detachment) or superficial, powdery efflorescence; (2) formation of nesquehonite/hydromagnesite crusts on wall paintings; and (3) nitratine growth causing pigment staining and detachment. These processes involve selective Mg²⁺ mobilization from magnesian-lime mortars and bacterial-induced formation of nitrates from guano, with consequent precipitation of degrading salts. The study confirms how characterization of all deterioration agents is fundamental to planning a viable cultural heritage conservation and restoration programme.     

Are secondary school graduates prepared for the studies of natural sciences? – evaluation and analysis of the result of scientific literacy levels achieved by secondary school graduates

ABSTRACT

Background: In Slovakia, no relevant information is available about the scientific literacy levels achieved by secondary school students.

Purpose: The objective of the research was to identify the levels of scientific literacy among students in the last year of grammar school and examine to what extent this determined the subject chosen for a school-leaving exam, which is related to a student’s personal preferences, as well as to the student’s profile and preparation for university education.

Sample: The research sample consisted of 221 students from 17 grammar schools located in various regions of Slovakia.

Design and methods: To identify the level of scientific literacy, we applied the Test of Scientific Literacy Skills.

Results: The students achieved the lowest success rate in the skill focused on the identification of the research design elements and its strengths and weaknesses. A comparably low success rate was also observed in the skill focused on the justification of the conclusions based on quantitative data. Other difficulties were identified in the field of understanding the basics of statistics, thus indicating an insufficient level of mathematical literacy of the students in the abovementioned field. By contrast, the highest success rate was achieved in the skill focused on the correct application of the scientific results for social purposes.

Conclusions: At the end of secondary school studies, the scientific literacy among Slovak students is at the average level. No differences were observed in terms of gender. In terms of the subjects chosen by the students for their school-leaving exams, we observed that those students who took a school-leaving exam in Biology or Chemistry achieved significantly better results in the test. By contrast, the students who reported on Geography and Civics as the subject of their school-leaving exam achieved significantly worse results in the test.
