High School Internships: Utilizing a Community Cultural Wealth Framework to Support Career Preparation and College-Going Among Low-Income Students of Color

This article investigates the experience of 229 low-income students of color who participated in an innovative high school internship program between 2011 and 2015. Using mixed methods (interviews, observations, and survey), the authors aim to understand the types of knowledge, information, and supports these students develop and expand in relation to careers and the college-going process. The authors draw on students' community cultural wealth to highlight the way the internship program supports students' aspirational, navigational, linguistic, resistant, and social capital.     

Developing capabilities in new ventures: a knowledge management approach

On the basis of a knowledge management perspective, this paper expands the literature on new ventures’ capabilities by considering how these firms fill knowledge gaps and develop the technological, marketing, management, and ICT capabilities they need to compete. In particular, this paper investigates the role of networks in these dynamics. Although new technology-based firms have great potential to introduce innovative products into the market, they might suffer from more critical knowledge gaps and capability weaknesses than established firms. The results of a quantitative investigation of an original data set of more than 400 Italian new ventures specializing in high-tech industries show that these firms acquire knowledge to support their capability growth mainly through the management of intense relations with multiple external sources of knowledge. In addition, capability development is supported by the variety of founders’ industry experience and the presence of young graduates among the founding team.     

Comparing Collective and Personal Professional Theories of Experienced Practitioners

A characteristic of being a professional is the internalisation of the collective professional theory (CPT)—the shared insights of professionals. Problems arise when different opinions stemming from professionals’ personal professional theories (PPTs) obscure a CPT’s content. This study argues that cooperating professionals’ CPTs form a so-called field and can be represented by concept maps. The relations between PPTs, CPTs, and fields are examined for the fields of accountancy and teaching. The results indicate that CPTs are more complex than PPTs, and that the teachers’ field is more diverse than the accountants’ field. These insights are important because socialisation in a field may be fostered if one is aware of CPTs and the surrounding field in relation to one’s PPT.     

Cultural capital and educational strategies. Shaping boundaries between groups of students with homologous cultural behaviours

Rather than assessing its causal effect on educational attainment, the authors of this article aim to use the concept of cultural capital to define a huge, complex and interconnected collection of educational and school strategies adopted by students and families and to examine the way that these strategies are related to school inequalities. Data analysed come from the 2009 Italian survey for the Program for International Student Assessment run by the OECD. A Latent Class Regression Analysis has been applied to categorize four groups of individuals who share specific cultural habits, educational dispositions and choices, and social status; in short, the four groups differentiate individuals with a different endowment of the intangible asset, cultural capital. Moreover, using the socio-economic status as a covariate we link the latent class membership probability with individuals’ social standing and, consequently school choices.     

What is the ‘Social’ in Climate Change Research? A Case Study on Scientific Representations from Chile

Over the last few decades climate change has been gaining importance in international scientific and political debates. However, the social sciences, especially in Latin America, have only lately become interested in the subject and their approach is still vague. Scientific understanding of global environmental change and the process of designing public policies to face them are characterized by their complexity as well as by epistemic and normative uncertainties. This makes it necessary to problematize the way in which research efforts understand ‘the social’ of climate change. How do ‘the climate’ and ‘the social’ interpenetrate as scientific objects? What does the resulting field look like? Is the combination capable of promoting reflexivity and collaboration on the issue, or does it merely become dispersed with diffuse boundaries? Our paper seeks to answer these and other related questions using Chile as a case study and examining peer-reviewed scientific research on the topic. By combining in-depth qualitative content analysis of each paper with a statistical meta-analysis, we were able to: characterize the key content and forms of such literature; identify divisions and patterns within it; and, discuss some factors and trends that may help explain these. We conclude that the literature displays two competing trends: while it is inclined to become fragmented beyond the scope of the ‘mitigation’ black box, it also tends to cluster along the lines of methodological distinctions traditionally contested within the social sciences. This, in turn, highlights the persistence of disciplinary divisions within an allegedly interdisciplinary field.

     

Study on some sorption properties of treated bentonites for their potential use as a moisture regulating system for the preservation of historical wooden elements

We report the first results of a research study aimed at developing a new strategy for the conservation of wooden structural elements present in historical buildings, based on moisture regulating systems. As has been happening for artefact preservation in museums, the idea is to develop systems based on the ability of some highly hygroscopic materials to moderate variations in relative humidity. These materials could adsorb and release moisture to reduce the extreme values of humidity in the micro-climate, for example between wooden beams and masonry. In order to experimentally verify this possibility using current, low cost and easy handling building materials, 5 bentonite samples were laboratory processed to improve their adsorbing properties by means of treatment with sodium carbonate at 3 concentrations: 2, 3 and 4% by weight. The effectiveness of ion exchange between sodium carbonate and bentonite was controlled by measuring the swelling volume of the bentonites. All the samples (n = 15) were tested for their hygroscopic properties. Adsorption isotherms were measured at 25 °C, using desiccators with silica gel, saturated salt solutions and bi-distilled water. A comparison between isotherms of one of the lower hygroscopic treated sample of bentonite and of a sample of wood and of a sample of brick and some numerical analyses with the Delphin code were made in order to evaluate the potential use of this bentonite as a moisture regulating system for the preservation of historical wooden elements. Results show that it seems to be possible to use bentonites as a moisture buffering material in order to reduce moisture content in wooden beams at least during their adsorption phase. It remains to investigate their desorption phase and their behaviour if they be in a saturation condition. Further studies are currently under way.     

An unsupervised aspect extraction strategy for monitoring real-time reviews stream

One of the most important opinion mining research directions falls in the extraction of polarities referring to specific entities (aspects) contained in the analyzed texts. The detection of such aspects may be very critical especially when documents come from unknown domains. Indeed, while in some contexts it is possible to train domain-specific models for improving the effectiveness of aspects extraction algorithms, in others the most suitable solution is to apply unsupervised techniques by making such algorithms domain-independent and more efficient in a real-time environment. Moreover, an emerging need is to exploit the results of aspect-based analysis for triggering actions based on these data. This led to the necessity of providing solutions supporting both an effective analysis of user-generated content and an efficient and intuitive way of visualizing collected data. In this work, we implemented an opinion monitoring service implementing (i) a set of unsupervised strategies for aspect-based opinion mining together with (ii) a monitoring tool supporting users in visualizing analyzed data. The aspect extraction strategies are based on the use of an open information extraction strategy. The effectiveness of the platform has been tested on benchmarks provided by the SemEval campaign and have been compared with the results obtained by domain-adapted techniques.     

The myplace4u Platform Project: A Tool for Place Branding and the Promotion of Literature

An expansion of the eZoomBook (eZB) platform, the ‘myplace4u’ project was designed for place branding and the promotion of literature by linking texts to places—geographical, historical, and touristic places visited physically or imaginatively. The platform allows contributors to collaboratively create and share multi-level books called “eZoomBooks” or digital enriched versions of the original version, organized according to tabs linked to place names in the original. A zooming function enables readers of the eZoomBooks on the platform to navigate freely between the original and enriched versions. Teacher-directed collaboration activities expand the applications of the eZB platform and myplace4u extension.
