Mass fractal characteristics of silica sonogels as determined by small-angle x-ray scattering and nitrogen adsorption

A sample series of silica sonogels was prepared using different water-tetraethoxysilane molar ratio (r(w)) in the gelation step of the process in order to obtain aerogels with different bulk densities after the supercritical drying. The samples were analyzed by means of small-angle x-ray-scattering (SAXS) and nitrogen-adsorption techniques. Wet sonogels exhibit mass fractal structure with fractal dimension D increasing from similar to2.1 to similar to2.4 and mass-fractal correlation length xi diminishing from similar to13 nm to similar to2 nm, as r(w) is changed in the nominal range from 66 to 6. The process of obtaining aerogels from sonogels and heat treatment at 500degreesC, in general, increases the mass-fractal dimension D, diminishes the characteristic length xi of the fractal structure, and shortens the fractal range at the micropore side for the formation of a secondary structured particle, apparently evolved from the original wet structure at a high resolution level. The overall mass-fractal dimension D of aerogels was evaluated as similar to2.4 and similar to2.5, as determined from SAXS and from pore-size distribution by nitrogen adsorption, respectively. The fine structure of the secondary particle developed in the obtaining of aerogels could be described as a surface-mass fractal, with the correlated surface and mass-fractal dimensions decreasing from similar to2.4 to similar to2.0 and from similar to2.7 to similar to2.5, respectively, as the aerogel bulk density increases from 0.25 (r(w)=66) up to 0.91 g/cm(3) (r(w)=6).

Metodología de formulación de indicadores para la mejora en la implantación de los programas de calidad. Aplicación al caso de las universidades públicas españolas

El planteamiento fundamental del trabajo ha consistido en explorar las posibilidades existentes para establecer una metodología basada en un modelo cuantitativo para la condensación de indicadores relacionados con los sistemas de calidad en el ámbito universitario público. El modelo incluye tanto la evaluación de activos tangibles como intangibles. Se ha seguido una metodología adaptada al planteamiento: - Realizando un estudio tipo DELPHI (DELPHI 1) entre las Unidades Técnicas de Calidad de las universidades de la Comunidad de Madrid, para conocer la situación de la implantación de metodologías de planificación estratégica en la universidad. - Definiendo tres niveles de gestión (bases, activos e indicadores) para la construcción del modelo cuantitativo. - Realizando una propuesta inicial de bases, activos e indicadores, incluyendo activos intangibles. - Realizando un segundo estudio tipo DELPHI (DELPHI 2) entre expertos con responsabilidad directiva en universidades, para debatir y revisar la propuesta. - Por último diseñando una metodología y la correspondiente herramienta para la condensación de los indicadores. En resumen, se ha generado una propuesta consolidada y actualizada de las bases estratégicas, los activos tangibles e intangibles y los indicadores en ambos casos, diseñándose una metodología (herramienta) que permite implementar la definición de los tres niveles de control, establecer una ponderación de cada uno de los elementos en los tres niveles y establecer una cuantificación de la importancia o contribución de cada elemento para la propia institución, y sirve para facilitar la toma de decisiones por priorización de actuaciones, establecer objetivos para los indicadores, valorar el grado de cumplimiento y modificar la estrategia de una institución universitaria. ABSTRACT The fundamental approach of the work has been to explore the possibilities to establish a methodology based on a quantitative model for condensing indicators related to quality assurance systems in Higher Education Institutions (HEI), particularly public universities. The model includes both assessment of tangible and intangible assets. A methodology adapted to the approach has been followed: - Performing a type DELPHI study (DELPHI 1) between the Technical Quality Units of the universities of the Community of Madrid, to know the level of implementation of strategic planning methodologies in HEI. - Defining three levels of management (bases, assets and indicators) to build the quantitative model. - Performing an initial proposal bases, assets and indicators, including intangible assets. - Making a second study type DELPHI (DELPHI 2) between experts with managerial responsibility in universities, to discuss and review the proposal. - Finally designing a methodology and related tool for condensing indicators. In short, a proposal consolidated and updated for strategic bases, the tangible and intangible assets and indicators of both types of assets has been performed. A methodology (tool) that allows to implement the definition of the three levels of control, establish a weighting each of the elements on three levels and establish a quantification of the importance and contribution of each element to the institution itself, has been designed. The methodology serves: - To facilitate decision-making by prioritizing activities. - To set targets for indicators. - To assess the degree of compliance and - To modify the strategy of the HEI.

A RELAÇÃO ENTRE CAPITAL HUMANO E CAPITAL PSICOLÓGICO

Os ativos intangíveis receberam atenção especial de estudiosos nos últimos anos, no contexto organizacional de gestão de pessoas, visto que foram desenvolvidas propostas teóricas para compreendê-los e mensurá-los. Ancorados nesta linha de investigação, encontram-se o capital humano e o capital psicológico. Enquanto o capital humano representa o que os trabalhadores sabem fazer, o capital psicológico compreende um estado mental positivo composto por autoeficácia, esperança, otimismo e resiliência. Este estudo teve, como objetivo geral, analisar as relações entre capital humano e capital psicológico. Tratou-se de um estudo quantitativo do qual participaram 60 trabalhadores, estudantes do último período do Curso de Administração, com idade média de 23,85 anos, sendo a maioria do sexo feminino, solteira e empregada. Os dados para o estudo foram coletados em salas de aula de uma universidade particular, situada na Região do Grande ABC, por meio de um instrumento auto aplicável, contendo uma medida intervalar de capital psicológico com 12 itens, validada para o Brasil, e uma de capital humano com seis questões, sendo duas para medir a dimensão experiência e quatro para aferir educação. Foi criado um banco eletrônico, o qual foi submetido a análises descritivas e de correlação (r de Pearson) por meio do SPSS, versão 19.0. Os resultados revelaram que os participantes detinham um capital humano representado por 4,38 anos médios de experiência de trabalho , e que a maioria (75%) havia revelado possuir no máximo cinco anos neste quesito. Quanto à dimensão educação do capital humano, a maioria (96,70%) não havia concluído nenhum curso de graduação, se dedicou entre 11 a 20 anos aos estudos (81,60%), não realizou intercâmbios de estudos (93%), enquanto 86,70% já incluíram, em seu currículo acadêmico, atividades complementares previstas no Plano Pedagógico do Curso de Administração que cursavam, bem como 73,30% realizaram entre um a três estágios curriculares. As análises indicaram um escore mediano de capital psicológico, acentuado pela dificuldade dos participantes para reconhecerem que estavam em uma fase de sucesso no trabalho e de conseguirem enxergar o lado brilhante das coisas relativas ao trabalho. Ao se investigar as relações entre o capital humano e capital psicológico não foram encontradas correlações significativas. Diante de tais resultados, pareceu provável que os participantes do estudo, por serem predominantemente jovens trabalhadores que ainda não concluíram um curso de graduação, embora tivessem em seu percurso de vida mais de 10 anos dedicados aos estudos e trabalhado por volta de cinco anos em média, ainda não reconheciam, em si, a presença de um consistente capital humano nem psicológico. A ausência de relação observada entre os dois ativos intangíveis preconizados por teóricos como importantes, para que o trabalhador pudesse contribuir com a empresa no alcance de suas metas, pareceu revelar que ainda eram necessários mais estudos e desenvolvimento de teorização, para sustentar não somente as hipóteses acerca de ativos intangíveis, como também permitir identificar a relação de dependência que pudesse existir entre as categorias de capital humano e psicológico.

Essays on corporate reputation: Antecedents and consequences

This dissertation studied the determinants and consequences of corporate reputation. It explored how firm-, industry-, and country-level factors influence the general public’s assessment of a firm’s reputation and how this reputation assessment impacted the firm’s strategic actions and organizational outcomes. The three empirical essays are grounded on separate theoretical paradigms in strategy, organizational theory, and corporate governance. The first essay used signaling theory to investigate firm-, industry-, and country-level determinants of individual-level corporate reputation assessments. Using a hierarchical linear model, it tested the theory based on individual evaluations of the largest companies across countries. Results indicated that variables at multiple analysis levels simultaneously impact individual level reputation assessments. Interactions were also found between industry- and country-level factors. Results confirmed the multi-level nature of signaling influences on reputation assessments. Building on a stakeholder-power approach to corporate governance, the second essay studied how differences in the power and preferences of three stakeholder groups—shareholders, creditors, and workers—across countries influence the general public’s reputation assessments of corporations. Examining the largest companies across countries, the study found that while the influence of stock market return is stronger in societies where shareholders have more power, social performance has a more significant role in shaping reputation evaluations in societies with stronger labor rights. Unexpectedly, when creditors have greater power, the influence of financial stability on reputation assessment becomes weaker. Exploring the consequences of reputation, the third essay investigated the specific effects of intangible assets on strategic actions and organizational outcomes. Particularly, it individually studied the impacts of acquirer acquisition experience, corporate reputation, and approach toward social responsibilities as well as their combined effect on market reactions to acquisition announcements. Using an event study of acquisition announcements, it confirmed the significant impacts of both action-specific (acquisition experience) and general (reputation and social performance) intangible assets on market expectations of acquisition outcomes. Moreover, the analysis demonstrated that reputation magnifies the impact of acquisition experience on market response to acquisition announcements. In conclusion, this dissertation tried to advance and extend the application of management and organizational theories by explaining the mechanisms underlying antecedents and consequences of corporate reputation.

The International <IR> Framework’s impact on the social and relationship disclosures in the healthcare industry

Abstract Background and Problem: The altering business world and the growing requests from stakeholders have resulted in the establishment of new reports. These are among others Sustainability reports and Integrated Reporting. On the contrary, traditional financial reports do not consider the significance of intangible assets in modern entities. The social and relationship capital has further shown to be important for firms, especially healthcare companies and pharmaceuticals, but is not as developed as other capitals within the <IR> framework and therefore not always included in annual reports. However too few disclosures within this area could lead to high liabilities. The IIRC launched the <IR> framework year 2013 as a solution, as it gives a more comprehensive view of the reporting entity. Within this framework there are six capitals: manufactured, human, financial, natural, intellectual and social and relationship.   Purpose: The purpose of this thesis is to find out how the International <IR> Framework has influenced the reporting of the social and relationship disclosures within the healthcare industry, to compare the reporting of the six medical firms chosen and to examine how the social concerns have been developed over time. Delimitations: This study is conducted over a period of three years, from year 2012 to year 2014. It only examines healthcare companies which use the International <IR> framework and it has solely focus on the social and relationship capital. All other capitals within the <IR> framework are excluded from the study. Method: This study has a qualitative research strategy and is based on information collected from published documents in form of annual reports. The annual reports from year 2010, 2011 and 2012 are used to find social and relationship disclosures and a disclosure scoreboard is used to find similarities, differences and patterns. Empirical Results and Conclusion: It has been found that the aggregated social and relationship disclosures have been reduced over time. The year followed by the release of the <IR> framework was seen to have the least disclosures and therefore conclusion was drawn that the <IR> framework had a negative influence on the social and relationship disclosures. There were also differences among the companies studied both in extent and content. The former could be linked to factors such as size and nationality and the latter could be linked to reputation preservation and legitimacy interests.

Biotin/avidin sandwich enzyme-linked immunosorbent assay for Culicidae mosquito blood meal identification

The knowledge of mosquitoes Culicidae host feeding patterns is basic to understand the roles of different species and to indicate their importance in the epidemiology of arthropod-borne diseases. A laboratory assay was developed aiming at standardizing the biotin-avidin sandwich enzyme-linked immunosorbent assay, which was unprecedented for mosquito blood meal identification. The enzyme-linked immunosorbent assay (ELISA) activity was evaluated by the detection of titers on each sample of the 28 blood-fed Culex quinquefasciatus. In light of the high sensitivity that the technique permits, by means of small quantities of specific antibodies commercially provided and phosphatase substrate which reinforces additional dilutions, human and rat blood meals were readily identified in all laboratory-raised Culex quinquefasciatus tested. The assay was effective to detect human blood meal dilutions up to 1:4,096, which enables the technique to be applied in field studies. Additionally, the present results indicate a significant difference between the detection patterns recorded from human blood meal which corroborate the results of host feeding patterns.
