Silica glass interaction with calcium hydroxide: a surface chemistry approach

The study of the interaction between silica glass and saturated Ca(OH)₂ solutions can be a useful approach to resolve the problem of the adhesion between lime-sand mortar and clay bricks. Since it is reasonable that the silica–calcium hydroxide system well simulates a brick–mortar system, experimental observations concerning the interaction of silica glass and this strong basic solution should be of value for the comprehension of the chemical reactions that could take place at the mortar–brick interface, maybe affecting the adhesion between the two building materials. We demonstrated the effects of saturated Ca(OH)₂ solutions on commercial pure silica glass (fused silica) and on silica films obtained via a sol–gel process by means of dip-coating. Silica samples were dipped in the solutions at different temperatures (room temperature, 60 and 80 °C) and at different time intervals (1 and 21 h) and then they were analysed by means of surface techniques: X-ray photoelectron spectroscopy (XPS), secondary ion mass spectrometry (SIMS) and atomic force microscopy (AFM). It has been shown that Ca(OH)₂ reacts with the silica glass network. The experimental results clearly show a very different behaviour of sol–gel silica with respect to fused silica, probably because of their different nanostructure. Many problems concerning the interaction of silica and Ca(OH)₂ are still to be solved, but the results of this research strengthen the idea that adhesion between lime-sand mortar and clay bricks is caused not only by carbonation of calcium hydroxide contained in the mortar, but even by some chemical reactions involving the brick constituents and calcium hydroxide itself. The final products, calcium silicates, may induce a chemical continuity between lime-sand mortar and clay bricks.     

‘Connected to Something’: Soccer and the Transnational Passions,Memories and Communities of Sydney's Italian Migrants

This paper explores the importance soccer can play in the lives, identities and memories of migrants by drawing on 32 oral history interviews conducted with Italians who settled in Sydney in the 1950s and 1960s. Sport can provide an illuminating lens for analysing the experience of migrants, because not only are sports sites of individual, regional, national and transnational identities, they can also facilitate social inclusion or, conversely, become sites of exclusion. Soccer in Australia is often celebrated as a multicultural game. At the same time, the expressions of the complex histories of migration, colonialism, exploitation and racial and ethnic discrimination that have shaped the game have often been silenced. The interviews show that soccer has been a key site of negotiation, agency and at times resistance for first and second generation migrants. We also argue that, while it is the de-ethnicisation of soccer that has understandably dominated media, political and academic debate, the concern of these migrants in recent years has been mostly with the loss of memory and with the removal of an important history made of shared relationships and bonding experiences.

从三种选举方式看中国农村基层党组织的民主建设

农村基层党支部的选举从组推直选到"两票制"(两推一选)和"一推一测一选"的发展,体现了当前我国农村基层民主化程度已经大大提高,农民群众的民主意识和民主素质也大大增强.三种选举方式有利有弊,但总的来说,是农村基层党组织建设的一个有益探索,是民主选举的一个大胆尝试.     

Improvisation: An analytic tool for examining teacher–child interactions in the early childhood classroom

This article explores the use of improvisation (improv) as a lens for viewing and describing teacher–child interactions. The author describes the relationship between the principles of improv and the characteristics of responsive teaching, and how improv can be used as a lens for seeing relational activity. The author hypothesizes that improv would provide a valuable tool for understanding and describing what is happening between teachers and children. An in-depth case study was conducted of an experienced early childhood teacher in a play-based classroom. Analysis was done using both the codes derived from the teacher–child interaction literature and improv theory. Improv analysis offered a nuanced picture of what early childhood teachers are doing in practice. The findings revealed that using improv provides a lens for seeing teacher–child interactions as an ensemble activity and what the teacher is doing in terms of its usefulness to the activity. While this study focused on a single teacher in one classroom, the findings demonstrate the potential of an improv lens for developing and deepening our understanding of early childhood teaching.

Exploring the structure of the Watson–Glaser Critical Thinking Appraisal: One scale or many subscales?

Critical thinking (CT) has been of longstanding interest among scholars, educators, and others who are concerned with thinking skills. The Watson–Glaser Critical Thinking Appraisal (WGCTA) is the oldest and among the most widely used and studied CT measure. It was constructed around five subscales (or CT skills): inference, recognition of assumptions, deduction, interpretation, and evaluation of arguments. This paper describes a two part analysis of the psychometric properties of the WGCTA, based on 13 sets of subscale inter-correlations and 60 sets of subscale means retrieved from published studies. We performed a meta-analysis on the inter-correlations of the10 combinations of subscales and found that all of the average correlations that resulted were significant, but that all but one was significantly heterogeneous. Subsequently, we conducted principal components analysis on 60 subscale means of two different versions of the WGCTA. Each produced a one-factor solution, accounting for 82.69% and 79.55% of the total variance, respectively. Together these two parts of this study suggest that the WGCTA should be viewed as a measure of general competency, and that the subscales should not be interpreted individually.
