Representation and knowledge exchange: A scoping review of photovoice and disability

Long-held misperceptions around disability continue to cause discrimination, stigmatization and harm. Effective, impactful research can challenge and change the status quo and influence decision-making. This scoping review seeks to understand how one arts-based research method, photovoice, interrogates issues in disability research. This article maps the current field of enquiry developing around disability photovoice research and examines two variables: representation and knowledge exchange. Thirty identified articles converged on the relevance to people with disability of community, accessibility, attitudinal change, adaption, economic empowerment and identity. Disseminating new knowledge generated through photovoice to a broader audience can have impact, especially on physical and attitudinal barriers. However, impact is rarely addressed in photovoice research. With its growing application in the disability field, photovoice research should monitor its influence on community and the environment to determine its benefit beyond the research setting

Self-Portraits for Social Change: Audience Response to a Photovoice Exhibition by Women with Disability

Negative attitudes about and behaviours towards women with disability are harmful and exclusionary, contributing to poorer health, income, educational, and employment outcomes. Our study focused on what audiences learnt, felt, and did (what changed) after viewing self-portraits and stories by women with disability. We questioned whether a public exhibition of their artworks, created through photovoice methodology, could be an effective platform to provoke social change and increase inclusion for people with disability. We collected audience response to our exhibition to address a research gap and to provide an example for other photovoice researchers. We employed interpretive thematic analysis through a generic social processes framework to interrogate responses. Our findings indicate that audiences learnt as much about themselves and their views of disability as they did about the women photographers. The audience described feelings of empathic engagement. They also expressed an unsettling between previously held assumptions around disability and new perspectives gained through the exhibition. Audiences changed how they view women with disability by engaging with the underlying messages of equality in the self-portraits and stories. Audiences thought the exhibition would change other people’s views, too, indicating a pathway to greater inclusion for people with disability

The contribution of 211 particles to the mechanical reinforcement mechanism of 123 superconducting single domains

Hardness and fracture toughness of Dy-123 single-domains were studied by Vickers micro-indentation. A significant anisotropy of the mechanical properties was observed. Hardness tests give higher values when performed in (001) planes rather than in planes parallel to the c-axis. Moreover cracks pattern around the indentation follows preferential orientation in planes parallel to the c-axis whereas a classical ''four-cracks'' pattern is observed in the (001) planes. It has been possible to show the crucial role played by the 211-particles in the deviating mechanism of cracks and the relevance of the 211-particle distribution high homogeneity in the material.Comment: 14 pages, including 5 figures and 1 Table. submitted to Supercond.

Prediction and control under uncertainty: Outcomes in angel investing

The article of record as published may be found at http://dx.doi.org/10.1016/j.jbusvent.2007.11.004Venture investing plays an important role in entrepreneurship not only because financial resources are important to new ventures, but also because early investors help shape the ventures' managerial and strategic destiny. In this study of 121 angel investors who had made 1038 new venture investments, we empirically investigate angel investors' differential use of predictive versus non-predictive control strategies. We show how the use of these strategies affects the outcomes of angel investors. Results show that angels who emphasize prediction make significantly larger venture investments, while those who emphasize nonpredictive control experience a reduction in investment failures without a reduction in their number of successes

Effectual versus predictive logics in entrepreneurial decision-making: Differences between experts and novices

The article of record as published may be found at http://dx.doi.org/10.1016/j.jbusvent.2008.02.002In support of theory, this study demonstrates that entrepreneurial experts frame decisions using an “effectual” logic (identify more potential markets, focus more on building the venture as a whole, pay less attention to predictive information, worry more about making do with resources on hand to invest only what they could afford to lose, and emphasize stitching together networks of partnerships); while novices use a “predictive frame” and tend to “go by the textbook.”We asked 27 expert entrepreneurs and 37MBAstudents to think aloud continuously as they solved typical decision-making problems in creating a new venture. Transcriptions were analyzed using methods from cognitive science. Results showed that expert entrepreneurs framed problems in a dramatically different way than MBA students

Current percolation and anisotropy in polycrystalline MgB2_2

The influence of anisotropy on the transport current in MgB$_2$ polycrystalline bulk samples and wires is discussed. A model for the critical current density is proposed, which is based on anisotropic London theory, grain boundary pinning and percolation theory. The calculated currents agree convincingly with experimental data and the fit parameters, especially the anisotropy, obtained from percolation theory agree with experiment or theoretical predictions.Comment: 5 pages, accepted for publication in Physical Review Letters (http://prl.aps.org/

Collaborating for Success! Building a Digital Learning Object Repository

At the Florida State College at Jacksonville, the Library and the Center for e-Learning collaborated to build a searchable repository of digital learning objects for faculty to easily locate and upload into their courses. In this program, the presenters will address how to create instructional information for online students in a format that is understandable, usable and accessible. Additionally, they will outline the way they developed an authoritative system of tagging and organizing these resources

Bioleaching to reprocess sulfidic polymetallic primary mining residues: Determination of metal leaching mechanisms

This is the final version. Available on open access from Elsevier via the DOI in this recordThe mining of non-ferrous metals produces the largest volume of metal-containing, extractive waste in Europe, and about 29% of all the waste produced in the EU-28. In the framework of the European project NEMO (Near-zero-waste recycling of low-grade sulfidic mining waste for critical-metal, mineral and construction raw-material production in a circular economy), new ways to valorize sulfidic tailings are being developed through the recovery of valuable metals and critical raw materials and the transformation of the residual in clean mineral fraction to be used for the mass production of cement, concrete and construction products. The first step of the NEMO concept consists of removing the sulfides remaining from primary bioleaching and extracting the metals in the residual material (known as ‘secondary ore’) using either enhanced bioleaching or an alkaline autoclave conversion processes. This paper focuses on one of the project case studies, the secondary ore, obtained from an operating heap leaching plant (Terrafame, Finland). This material still contains several sulfide minerals (pyrrhotite, pyrite, sphalerite, pentlandite, violarite, chalcopyrite) and significant amounts of metals (Zn, Ni, Cu, Co, rare earth elements). The study aimed to characterize the mineralogy of the secondary ore and perform bioleaching in 2 L-stirred tank reactors, with three microbial cultures growing at 42, 48 and 55 °C. These results were compared to abiotic experiments, performed under the same conditions. Nickel was released very quickly, suggesting that part of Ni dissolved in the primary heap was re-precipitated and remained in the secondary ore. By contrast, Cu dissolution was much slower but the kinetics were substantially improved when the temperature was increased to 55 °C. Cobalt dissolution kinetics were highly improved by the bacterial activity, whatever the consortium. This is consistent with the presence of Co in the pyrite in the secondary ore.European Union Horizon 202

Choice of steel for the ISABELLE magnet tubes

It is concluded that the low temperature ductility of cast duplex stainless steels can be reduced by high ferrite content, excessive amounts of nitrogen or strong carbide forming elements, and lack of heat treatment particularly at higher ferrite levels. While all samples investigated, with the exception of No. 14 (non-heat treated 12% delta), had mechanical properties more than adequate for the intended service, it was felt advisable to modify the specifications for the tube steels. The requirement is for CF8 as per ASTM specification number A743 with the following modifications: nitrogen content must not exceed 0.08%; niobium content must not exceed 0.1% and total of all carbide formers (Nb, Ti, V, W) must not exceed 0.2%; ferrite content of the casting, as determined from the heat chemistry using the DeLong diagram, must not exceed 10%. A743 already calls for suitable solution heat treatment
