Evaluation of the castability of a Co-Cr-Mo-W alloy varying the investing technique

O objetivo deste estudo foi comparar a fusibilidade de ligas de Co-Cr-Mo-W (Remanium 2000), Ni-Cr (Durabond) e Co-Cr-Mo (Vera-PDI), incluídas em revestimentos à base de fosfato, sílica ou utilizando uma técnica mista. Uma rede de nylon quadrada (10 X 10 mm) com 100 espaços abertos serviu de modelo para construção de padrões de cera, que foram incluídos com revestimento à base de sílica, revestimento fosfatado e técnica mista (camada de revestimento fosfatado com 2 mm de espessura + revestimento à base de sílica). Quarenta e cinco espécimes (5 para cada condição experimental) foram fundidos sob chama de gás-oxigênio e a seguir jateados com óxido de alumínio. O número de segmentos fundidos completos foi contado para obter uma percentagem designada como "valor de fusibilidade", representando a precisão da liga em reproduzir os detalhes do molde. A análise estatística por meio de ANOVA a dois critérios e teste Tukey mostrou que, comparando-se as ligas, a Remanium 2000 teve fusibilidade estaticamente semelhante (p>0,05) à da Vera PDI e inferior à da liga Durabond (p<0,05). Considerando os resultados da técnica mista, a liga Remanium 2000 teve menor valor de fusibilidade (p<0,05) que as ligas Durabond e Vera PDI, que apresentaram valores estatisticamente semelhantes entre si (p>0,05). Concluindo, a fusibilidade da liga de Co-Cr-Mo-W (Remanium 2000) foi comparável à da liga de Co-Cr (Vera PDI) e inferior à da liga de Ni-Cr alloy (Durabond). À exceção da liga Remanium 2000, a técnica de inclusão mista aumentou consideravelmente a capacidade das ligas testadas de reproduzir os detalhes do molde, quando comparada à técnica de inclusão em revestimento fosfatado. A técnica de inclusão mista representa uma alternativa para melhorar a fusibilidade de ligas de metais básicos sem afetar a qualidade superficial das peças metálicas.

Investing in the Homeland: Foreign Assets and Patterns of Immigrant Economic Incorporation

This dissertation consists of three separate studies that examine patterns of immigrant incorporation in the United States. The first study tests competing hypotheses derived from conflicting theoretical frameworks−transnational perspective and cross-national framework− to determine whether transnational engagement and incorporation are concurrent processes among Chinese, Indian, and Mexican immigrants. This study measures transnational engagement and incorporation as home and home country asset ownership using multi-panel, nationally representative data from the New Immigrant Survey (NIS) collected in 2003 and 2007. Results support a cross-border framework and indicate that transnational asset ownership decreases among all immigrant groups, while U.S. asset ownership increases. Findings from this study also indicate that due to disadvantaged pre-migration SES and low human capital, Mexican immigrants are less likely than other immigrants to own home country assets during the year after receiving their green card.

The second study examines the doubly disadvantaged position of elderly immigrants in the U.S. wealth distribution by applying the life course perspective to the dominance-differentiation theory of immigrant wealth stratification. I analyze elderly immigrant wealth in respect to U.S.-born seniors and younger immigrant cohorts using two data sets: the Survey of Income and Program Participation (SIPP) and the New Immigrant Survey (NIS). The Survey of Income and Program Participation (2001 to 2005) is a nationally representative survey of U.S. households. The first series of analyses reveals a significant wealth gap between U.S.- and foreign-born seniors which is most pronounced among the wealthiest households in my sample; however, U.S. tenure explains much of this difference. The second series of analyses suggests that elderly immigrants experience greater barriers to incorporation compared to their younger counterparts.

In the third study, I apply a transnational lens to the forms-of-capital and opportunity structure models of entrepreneurship in order to analyze the role of foreign resources in immigrant business start-ups. I propose that home country property use represents financial, social, and class resources that facilitate immigrant entrepreneurship. I test my hypotheses using survey data on Latin American immigrants from the Comparative Immigrant Entrepreneurship Project. Findings from these analyses suggest that home country asset ownership provides financial and social capital that is related to an increased likelihood of immigrant entrepreneurship.

Give and You Shall Receive: Investing in the Careers of Women Professionals

Purpose – The purpose of this paper is to explore what organizations can do to facilitate the retention and advancement of women professionals into top leadership positions. A social exchange framework is applied to examine ways organizations can signal support for and investment in the careers of women professionals, and ultimately the long-term work relationship. Design/methodology/approach – This paper employed a qualitative methodology; specifically, semi-structured interviews with 20 women executives, in primarily the US hospitality industry, were conducted. The interviews were recorded, transcribed, and content analyzed. Findings – Organizations are likely to strengthen the retention of their female professionals if they signal support through purposeful, long-term career development that provides a sightline to the top, and ultimately creates more female role models in senior-level positions. Organizations can also signal support through offering autonomy over how work is completed, and designing infrastructures of support to sustain professionals during mid-career stages. Findings are used to present a work-exchange model of career development. Research limitations/implications – This research is an exploratory study that is limited in its scope and generalizability. Practical implications – The proposed work-exchange model can be used to comprehensively structures initiatives that would signal organizational support to – and long-term investment in – female professionals and enable them to develop their career paths within their organizations. Originality/value – Through offering a work-exchange model of career development, this paper identifies components of organizational support from a careers perspective, and highlights the factors that could potentially contribute to long-term growth and retention of women professional

Investing for impact. An exploration of impact investments in rural Ghana

This thesis offers an exploration of impact and social investments for agricultural development projects in Sub-Saharan Africa. It does so through the case of SustAgric-Africa (SAA), a social enterprise that aims to lift smallholder farmers out of poverty through the promotion of sustainable farming and operates with capital provided by a variety of investors who are committed to pairing financial returns with social and environmental outcomes. The thesis sets off to answer the following research questions: What is the moral dimension that emerges in finance with the establishment of environmental and social criteria? What kind of arrangements do social and impact investments give origin to? Is it possible to talk about a ‘spirit of the gift’ in such arrangements? What happens when abstract and globalizing ideas around ‘impact’ hit the ground? Drawing from the STS and Actor-Network Theory, I look at the formation engendered by social and impact investments in terms of a socio-technical arrangement, and look at the movements of “objects” between the main actors in terms of circuits. In these processes ideas about ‘value’ and ‘values’ articulate in complex ways in the interplay of gift, debt and credit in the relationships among the three main categories of involved actors: investors, SAA, and the farmers. In the case of SAA, I contend that the ways abstract and globalising ideas about ‘impact’ hit the ground produce uncertain results and contribute to the reproduction of inequalities and unequal wealth distribution and accumulation, deepening ongoing processes of financialization. However, my ethnography also reveals how actors depicted as beneficiaries of impact and social policies and resources, far from being passive recipients of policies and resources, actually question and appropriate them, potentially unsettling the whole arrangement and the moral and ethical claims underpinning it.

Success attitudes of young ophthalmologists in the first decade of their career

PURPOSE: To describe the main success attitudes of young ophthalmologists in the first decade of their career. METHODS: This descriptive study comprised subjects selected from a sample of ophthalmologists who were participating in a congress, using a semi-structured questionnaire. The inclusion criteria were as follows: ophthalmologists under the age of 40 years, within 5-10 years from ophthalmology residency conclusion. The subjects were asked about the three main success attitudes in their personal experience during the first years of ophthalmology practice. After the initial results, the 10 most frequently mentioned attitudes were listed and volunteers were again interviewed to choose, within the latter list, the three main attitudes. RESULTS: Forty-eight ophthalmologists were interviewed, 24 (50%) were male; the mean age was 37 years (SD: 2 years, range: 33-40 years) and the mean time from ophthalmology residency conclusion was 8 years (SD: 1 year, range: 5-10 years). The frequency of such mentioned success attitudes were as follows: to invest in professional updating (22.9%), to have a good relationship with patients and professional partners (18.8%), to prioritize individual and family happiness (12.5%), initially to work in an established group (11.1%), to work in public service (9.7%), to have their own business with a homogeneous group (7.6%), to save money (7.6%), to be ready to resume work (4.2%), to get business administration skills (4.2%), and to have professional insurance (0.7%). CONCLUSIONS: The three main success attitudes consisted in investing in professional updating (22.9%), maintaining a good relationship with patients and professional partners (18.8%), and prioritizing individual and family happiness (12.5%). Although these results should not be generalized, they are helpful not only for those ophthalmologists at the beginning of a career but also those who want to reflect on what to prioritize in their professional practice.

FOREIGN INVESTMENT AND THE BRAZILIAN REAL ESTATE MARKET

This article discusses the main aspects of the Brazilian real estate market in order to illustrate if it would be attractive for a typical American real estate investor to buy office-building portfolios in Brazil. The article emphasizes: [i] - the regulatory frontiers, comparing investment securitization, using a typical American REIT structure, with the Brazilian solution, using the Fundo de Investimento Imobiliario - FII; [ii] - the investment quality attributes in the Brazilian market, using an office building prototype, and [iii] - the comparison of [risk vs. yield] generated by an investment in the Brazilian market, using a FII, benchmarked against an existing REIT (OFFICE SUB-SECTOR) in the USA market. We conclude that investing dollars exchanged for Reais [the Brazilian currency] in a FII with a triple A office-building portfolio in the Sao Paulo marketplace will yield an annual income and a premium return above an American REIT investment. The highly aggressive scenario, along with the strong persistent exchange rate detachment to the IGP-M variations, plus instabilities affecting the generation of income, and even if we adopt a 300-point margin for the Brazil-Risk level, demonstrates that an investment opportunity in the Brazilian market, in the segment we have analyzed, outperforms an equivalent investment in the American market.

The Effect of Coating Patterns with Spinel-Based Investment on the Castability and Porosity of Titanium Cast into Three Phosphate-Bonded Investments

Purpose: This study evaluated the effect of pattern coating with spinel-based investment Rematitan Ultra (RU) on the castability and internal porosity of commercially pure (CP) titanium invested into phosphate-bonded investments. The apparent porosity of the investment was also measured. Materials and Methods: Square patterns (15 x 15 x 0.3 mm(3)) were either coated with RU, or not and invested into the phosphate-bonded investments: Rematitan Plus (RP), Rema Exakt (RE), Castorit Super C (CA), and RU (control group). The castings were made in an Ar-arc vacuum-pressure machine. The castability area (mm(2)) was measured by an image-analysis system (n = 10). For internal porosity, the casting (12 x 12 x 2 mm(3)) was studied by the X-ray method, and the projected porous area percentage was measured by an image-analysis system (n = 10). The apparent porosity of the investment (n = 10) was measured in accordance with the ASTM C373-88 standard. Results: Analysis of variance (One-way ANOVA) of castability was significant, and the Tukey test indicated that RU had the highest mean but the investing technique with coating increased the castability for all phosphate-bonded investments. The analysis of the internal porosity of the cast by the nonparametric test demonstrated that the RP, RE, and CA with coating and RP without coating did not differ from the control group (RU), while the CA and RE casts without coating were more porous. The one-way ANOVA of apparent porosity of the investment was significant, and the Tukey test showed that the means of RU (36.10%) and CA (37.22%) were higher than those of RP (25.91%) and RE (26.02%). Conclusion: Pattern coating with spinel-based material prior to phosphate-bonded investments can influence the castability and the internal porosity of CP Ti.

A criança com Síndrome de Asperger na educação infantil : um estudo de caso

Esta pesquisa teve como objetivo compreender as ações pedagógicas constituídas por uma unidade municipal de ensino de Vitória/ES, visando ao processo de inclusão escolar de uma criança com Síndrome de Asperger no contexto da Educação Infantil. Contou com as contribuições teóricas dos estudos da matriz histórico-cultural e de autores dedicados a estudar a infância, como Kramer, Sarmento, Aries, dentre outros, bem como de pesquisadores interessados em investigar os pressupostos da Educação Especial em uma perspectiva inclusiva. Como aporte teórico-metodológico, apoiou-se no estudo de caso do tipo etnográfico que advoga pela possibilidade de, por meio da pesquisa científica, produzir conhecimento sobre a realidade social. O trabalho de pesquisa foi realizado em uma unidade municipal de Educação Infantil de Vitória/ES, envolvendo uma criança com Síndrome de Asperger, professores, pedagogos, dirigente escolar e responsável pelo estudante investigado. O processo de coleta de dados se efetivou no período de março de 2013 a setembro de 2013. O pesquisador esteve de uma a duas vezes por semana no campo de pesquisa, participando das observações em sala de aula, em espaços para planejamento e formação continuada e também observando momentos informais na entrada, recreio e saída dos alunos. Para a organização do estudo, trabalhou com quatro eixos: a) ações implementadas em favor do processo de inclusão escolar de alunos com Síndrome de Asperger no contexto da Educação Infantil; b) proposta pedagógica do CMEI “Alegria da Cinderela”: espaços de planejamento, formação e utilização dos apoios pedagógicos para a inclusão escolar; c) concepções dos profissionais envolvidos na pesquisa e da família sobre a inclusão escolar da criança com Síndrome de Asperger; d) principais possibilidades e/ou dificuldades encontradas pela unidade de ensino mediante o processo de ensino-aprendizagem da criança com Síndrome de Asperger. Como resultados, a pesquisa aponta: a importância de pensar nessas crianças como sujeitos de direitos e capazes de aprender; a necessidade de investimentos na formação inicial e continuada de professores para que os estudantes tenham maiores possibilidades de aprender; a urgência de o professor assumir a inclusão escolar como um movimento ético comprometido com a formação e com o reconhecimento da diversidade/diferença humana; a necessidade de reconhecer o cotidiano da Educação Infantil como um rico espaço para todas as crianças se desenvolverem e produzirem conhecimentos com seus pares e por meio das mediações pedagógicas dos professores.

Measuring fund performance using multi-factor models: evidence for the Portuguese market

This paper examines the performance of Portuguese equity funds investing in the domestic and in the European Union market, using several unconditional and conditional multi-factor models. In terms of overall performance, we find that National funds are neutral performers, while European Union funds under-perform the market significantly. These results do not seem to be a consequence of management fees. Overall, our findings are supportive of the robustness of conditional multi-factor models. In fact, Portuguese equity funds seem to be relatively more exposed to smallcaps and more value-oriented. Also, they present strong evidence of time-varying betas and, in the case of the European Union funds, of time-varying alphas too. Finally, in terms of market timing, our tests suggest that mutual fund managers in our sample do not exhibit any market timing abilities. Nevertheless, we find some evidence of timevarying conditional market timing abilities but only at the individual fund level.
