Der volle Inhalt der QuelleDespite the impressive economic growth of African economies since 2000s, the actual context is threatening the sustainable development of the private sector. Large institutional imperfections and poor business environment are hindering the development of firms and are paving the way for a more persistent informal sector. This thesis reopens the controversial debate about the informal sector by looking at its entrepreneurial capacity rather than its threats. In order to understand the strong persistence of this sector despite its confirmed negative impacts, we investigate the extent to which the relationship between formal and informal firms, through market competition, could affect the Egyptian economy. We find that more intense competition stemming from informal firms can drive formal firms to become more productive. We also extend our analysis to Sub-Saharan African countries by underlining the effect of taxation and regulation on the strength of competition between formal and informal firms. Our findings call on the importance of introducing the informal sector in undertaken policies that target the reform of taxation and regulations in Africa. These policies should also target the firms’ access to source of finance, infrastructure and training as effective tools inducing the formalization process and fostering economic growth. Therefore, this thesis provides evidence on the importance of revisiting the impacts of the informal sector in developing countries by looking at it as a driver of economic growth rather than a threat

Der volle Inhalt der QuelleEconomic activities and trade are deeply intertwined with the management of violence, posing a significant challenge in the modern global system. This violence, spanning expropriation, destruction, piracy, terrorism, conflicts, and wars, affects all countries. The exposure to violence leads to substantial economic costs, hindering trade and development. In response, states have enforced security policies and expect economic benefits in return. The thesis analyses this connexion between international insecurity and economic activities. The first chapter focuses on the military alliances’ effect on trade – treaties specifically designed to reduce international insecurity. In the second chapter, we dig into the complexity of military events and investigate their micro-economic impact on formal firms. Finally, chapter three analyses the consequences of country-pair-specific sensitivity to exchange costs, including insecurity, on real revenues

Capes
O presente trabalho trata da obtenção e caracterização de filmes planos de PEBDL/bentonita com e sem a incorporação de um agente compatibilizante (PE-gMA). Os filmes foram obtidos por extrusão plana e suas propriedades mecânicas, de permeabilidade e térmicas foram avaliadas em função do teor (0 a 5% em massa) e do tipo de carga incorporada. Duas argilas foram utilizadas: a) uma bentonita de origem local (Paraibana) e b) uma argila organofílica comercial importada. A argila paraibana foi purificada e organofilizada antes de ser incorporada à matriz polimérica. As argilas utilizadas foram caracterizadas através da sua capacidade de troca catiônica (CTC), por difração de raios-x (DRX), por espectroscopia no infravermelho por transformada de Fourier (FTIR), análise da composição química por energia dispersiva (EDX), análise granulométrica e por análise termogravimétrica (TGA). Os nanocompósitos obtidos na forma de filmes planos foram caracterizados por DRX, microscopia eletrônica de varredura (MEV), permeabilidade ao vapor de água e aos gases O2 e CO2, propriedades mecânicas, análise termogravimétrica (TGA) e análise da calorimetria exploratória diferencial (DSC). Os filmes de nanocompósitos com compatibilizante apresentaram morfologia intercalada/parcialmente esfoliada e os filmes sem a presença do compatibilizante apresentaram morfologia compatível com a de nanocompósitos intercalados/microcompósitos. Os resultados das propriedades mecânicas mostraram que os filmes preparados com o agente compatibilizante apresentaram propriedades superiores à da matriz pura e às dos outros sistemas preparados. A presença do agente compatibilizante reduziu significativamente a permeabilidade ao vapor de água e a permeabilidade ao gás O2 nos filmes, mas os filmes sem a presença do agente compatibilizante apresentaram aumento desta propriedade quando comparados ao filme de PEBDL puro. As analises térmicas mostraram um aumento discreto da estabilidade térmica para os filmes de nanocompósitos preparados com o agente compatibilizante.
The present work deals with the manufactur and characterization of flat films of LLDPE/bentonite with and without the incorporation of a compatibilizing agent (PE-g-MA). The films were obtained by flat die extrusion and its mechanical, permeability and thermal properties were evaluated in function of clay content (0 to 5% by mass) and clay identity. Two clays were used: a) a local bentonite (from Paraiba) and b) an imported commercial organoclay. The local clay was purified and organophilized before being incorporated into the polymer matrix. The clays were characterized by cation exchange capacity (CEC), x-ray diffraction (XRD), spectroscopy Fourier transform infrared (FTIR), analysis, chemical composition by dispersive energy (EDX), particle size analysis and by thermogravimetric analysis (TG). Nanocomposites obtained as flat films were characterized by XRD, scanning electron microscopy (SEM), water vapor, O2 and CO2 gas permeability, mechanical properties, thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). The nanocomposite films with compatibilizer showed an intercalated/partially exfoliated morphology while the morphology of the films without compatibilizer was compatible with that of intercalated nanocomposites/microcomposites. The mechanical properties of the films prepared with the compatibilizer agent were higher than those of the neat matrix and the other systems prepared. Compatibilizing agent addition significantly reduced water vapor and O2 gas permeability in films, but the films without the presence of the compatibilizer showed an increase of this property when compared to pure LLDPE film. The influence of compatibilizer addition on CO2 permeability was small. Thermal analyzes showed a slight increase of thermal stability for the films of nanocomposites prepared with the compatibilizing agent.

Der volle Inhalt der QuelleConstruction activities are inherent complex, as a result of a great number of interests and large amount f information involved, what makes risk management and conflict prediction difficult tasks, eventually leading to legal disputes. Construction and engineering contracts often do not cover all risks involved, leading to claims and resulting in losses of time and money for construction firms, engineering companies, property developers, and other stakeholders. The judiciary system is very slow and expensive, and, as an alternative, private arbitration courts were created by federal law 9307/96. Private managed, these courts are expected to be faster, less expensive and confidential. The aim of this research is to analyze the frequency and conditions of the use of arbitration in contracts in civil construction projects, identifying advantages and disadvantages from the point of view of construction companies, aiming to suggest actions as to increase its use. The research method includes bibliographic review and a survey with three institutional private arbitration organizations, three construction firms and three law firms.

Der volle Inhalt der QuelleThe objective of this work was to study the influence of the addition of tin ion (Sn4+) into the SrTiO3 compound lattice, to replace the titanium ion (Ti4+). The aim was to optimize the electrical properties of SrTiO3 compound and, as a consequence, to obtain an improvement of its performance as a gas sensor in the thin films samples. To perform the deposition of these thin films through Electron Beam Deposition (EBD), ceramic targets of composition SrTi1-xSnxO3 (STSO) with x = 0; 0.20; 0.40; 0.60; 0.80; 0.85; 0.90; 0.95; and 1 were obtained by the modified polymer precursor method. The solid solution formation sequence was determined by the Rietveld refinement of the STSO sintered powdered samples, obtained by both polymeric precursor and solid-state reaction methods, showing that the transition from the cubic Pm3̄m phase of the SrTiO3 compound to the orthorhombic Pnma phase of the SrSnO3 compound does not depend on the synthesis method. The measurements of Raman spectroscopy and absorption of X-rays (XANES, at Ti K-edge), of the powdered samples obtained by both synthesis methods and of the thin films obtained by EBD, revealed the existence of a local disorder in the SrTiO3 compound lattice which decreases with increasing of temperature and with decreasing of Sn concentration. The STSO thin films were evaluated as sensors using the O3 and NH3 gases. In measurements accomplished with the ozone gas (O3), the results showed that thin films of 100 nm thickness had a higher sensitivity. The sample having 60% of tin showed the best performance at 350°C for 0.15 ppm of ozone gas. The performance analysis related to the selectivity of the STSO films indicated they were not selective and that presented a higher response to the ozone gas when compared to the NH3 gas.

Der volle Inhalt der QuelleThis work presents the synthesis, characterization and properties of metallic phthalocyanines. For the palladium phthalocyanine (PdPc) and rhodium phthalocyanine (RhPc), only one fraction could be totally purified for work with the Langmuir-Blodgett (LB) technique. The fractions of ruthenium phthalocyanine (RuPc) could not be sufficiently purified for the fabrication of Langmuir and LB films. The film properties of rhodium phthalocyanine and ytterbium bisphthalocyanine (YbPc2), synthesized in a previous work, were investigated, which showed results depending on the experimental conditions. For YbPc2, the positioning of the pressure sensor affects the collapse pressure of the Langmuir films. This is only observed in semi-amphiphilic compounds. The surface potential of the Langmuir films depends on the compression speed, but these differences are not observed in LB films. A strong chemical interaction between stearic acid and RhPc was observed, which is unprecedented for phthalocyanines. The interaction seems less intense in LB films than in solution. The arcas per molecule in the condensed phase for the ytterbium and samarium bisphthalocyanines and rhodium phthalocyanine were 69, 60 and 75 Å2 and the collapse pressures were 52, 54 and 57 mN/m, respectively. These results show the similar characteristics of the diferente phthalocyanines. However, the surface potential was lower for RhPc, probably due to a smaller dipole component normal to the water surface. The electrochemical behavior of YbPc2 LB films depends on film thickness. In thicker films, ion diffusion is hindered, mainly in the cathodic process. LB films of YbPc2 and PdPc showed electrochromism, with changes in color upon the application of distinct potentials. In Raman spectroscopy using the 633 nm laser line, the most intense band occurs at 675 cm-1 for RhPc and YbPc2. PdPc behaves differently, with the most intense band at 1520 cm-1. Analyzing the results in the light of data in the literature, it was concluded that the dominating factor for the Raman spectra is the oxidation state of the metal. Yb and Rh metais are likely to be in the same oxidation state, differently from Pd . Comparing results from atomic force microscopy (AFM) and Raman mapping with LB films from YbPc2 mixed with stearic acid, it was observed that LB films with a larger amount of YbPc2 are more homogeneous

Der volle Inhalt der QuelleThe aim of this work was the development of prototypes of an extruder and an equipment for production of films by lamination and solvent casting. After the calculations required for assembly the equipments, the drawings were done in CAD (SolidWorks Software version 2009). Once defined the optimal combinations of polymer and plasticizer, the best conditions for film production were done. The basic size of the extrusion equipment was in direct proportion to the extent of the blade and the desired total output of product. The result was a matrix with a definied format, and a screw with constant pitch and constant diameter. For the production of films by solvent evaporation, after the calculations of mass transfer by convection at external flow, a structure was set up in acrylic serving as a system for drying and rolling using mills with different thicknesses. The films for extrusion were prepared from maltodextrin, microcrystalline cellulose and glycerin, while for the production of films by solvent evaporation, the polymer choise was pullulan. It was found that the extrusion method allowed good productivity, but in return, by the method of solvent evaporation, we obtained a higher quality, and the possibility of making films with better organoleptic characteristics. The films were thinner, which in turn leds to shorter disintegration time. Concerning the method of solvent evaporation, it was concluded that drying and lamination are critical steps for the production, since if not properly performed, both can affect visual appearance, mechanical properties, weight and disintegration time.

Der volle Inhalt der QuelleThis thesis describes the process of making a film on the Tibetan Culture. The film-maker conducted field-work in 1980-81 for a period of eight months in a Tibetan village in Northern India. The film is based on a number of long interviews with villagers and monks, concerning social life and customs (past and present) of Tibetan refugees in India. The interviews where carried on during this period of research. The thesis deals with hall the problems involved in the making of an ethnographic film taking into account of the theoretical, methodological and practical implications. The focus of the film is a single person (a young businessman going back to Tibet for the first time) whose portrait (and journey from Katmandu to Lhasa) is a pretext and an artifice to explore and bring to light some aspects of Tibetan Culture. Methods and strategies in filming and editing are discussed at different levels and in relation to certain aspects of Tibetan Culture

Der volle Inhalt der QuelleEn términos generales, el ensayo del Ground Penetrating Radar (GPR) aplicado a la ingeniería de carreteras, suele circunscribirse a la determinación geométrica de la estructura del firme mediante el análisis de la onda en el dominio del tiempo.En muchas ocasiones, suele utilizarse para apoyar el cálculo del módulo de rigidez de las capas de la estructura mediante el método conocido como retro-cálculo, según indican las principales guías de diseño empírico-mecanicistas de firmes asfálticos. Sin embargo, los principios geofísicos que sustentan el ensayo permiten, de forma indirecta y mediante la interpretación de variables asociadas a la respuesta física de los materiales frente a una onda electromagnética, obtener datos relacionados con el estado estructural de un firme. Dichas variables pueden asociarse a patologías estructurales relacionadas, por ejemplo, con la presencia de humedad o la falta de adherencia entre las capas del firme.En este trabajo se aborda las posibilidades que tiene el ensayo de GPR mediante el análisis de la onda en sus dimensiones temporal y frecuencial, con el propósito de permitir el diseño de futuros indicadores de estado, asociados al deterioro estructural de un firme. Los indicadores de estado basados en la respuesta de la señal de GPR permitirán reducir considerablemente el número de ensayos destructivos practicados hoy día en los firmes tales como la extracción de testigos, u otros ensayos no destructivos pero igualmente caros y de elevada complejidad logística, como son los ensayos de deflexión.

Der volle Inhalt der QuelleThis thesis dissertation includes the synthesis and characterization of sustainable materials including bismuth (Bi), bismuth ferrite (BiFeO3) and copper-based shape memory alloys. Electrodeposition and sputter deposition were employed as the synthesis techniques. Electrodeposition was used in order to obtain micron and submicron sized Bi particles from an aqueous electrolyte and BiFeO3 films when electrodeposition from dimethylformamide bath was followed by heat treatment of the resulting coatings in open air. Sputter deposition was applied to produce copper-aluminium-nickel (Cu–Al–Ni) shape memory alloys. Two approaches were followed to obtain the Cu–Al–Ni thin films. In one of the methods applied, multilayers of Cu-Ni and Al were first sputtered, followed by heat treatment and quenching in iced water while, in the other method, epitaxial growth of austenitic Cu–Al–Ni on MgO substrate was obtained by sputter deposition along with in-situ heat treatment. Morphological characterization of the samples was carried out by scanning electron microscopy (SEM). X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used for structural characterization. For the investigation of magnetic properties of the bismuth ferrite films, vibrating sample magnetometry (VSM) was implemented. In order to observe the martensitic transformation behaviour in the sputter deposited Cu–Al–Ni films, electrical resistivity measurements with respect to temperature were carried out. The morphology of the Bi particles was investigated as a function of the bath composition, substrate activity and the applied potential. In all cases, it was seen that as the absolute value of the applied potential increased, an evolution in the particle morphology from hexagons to dendrites was observed. Moreover, Bi particles were more uniformly distributed over the substrate when sodium gluconate was added to the electrolyte. The characterization studies for the BiFeO3 films prepared by electrodeposition and subsequent heat treatment revealed that rhombohedral BiFeO3 (interesting for its multiferroic character) formed around 600 °C. At lower and higher temperatures, secondary binary and ternary oxide phases were encountered. The observed weak ferromagnetic-like behaviour in the film annealed at 600 °C is mainly ascribed to nanostructuration which, in turn, favours the occurrence of spin canting in the BiFeO3 phase. In the free-standing Cu–Al–Ni films prepared by sputter deposition and subsequent heat treatment, it was observed that a gradual change in the film composition (i.e. decrease in the Al content and an increase in the Ni content) resulted in a shift in the room temperature phase formation from martensite to austenite. The obtained films exhibited a randomly oriented polycrystalline structure. On the other hand, for the austenitic Cu–Al–Ni film grown at high temperature on MgO substrates, a (200) textured growth of the film was observed due to the epitaxial relationship between the film and the substrate. The electrical resistance change vs. temperature measurements revealed that martensitic transformation was observed in the textured austenite film whereas it was not observed in the randomly oriented austenite film. The potential of the materials investigated throughout this Thesis as sustainable candidates in micro- and nanosystems is outlined.

As redes metalorgânicas (ou MOF, do inglês Metal-Organic Frameworks) pertencem à classe dos polímeros de coordenação (ou CP, do inglês coordination polymers) e exibem características como porosidade e cristalinidade. Em particular, as MOF bidimensionais têm despertado o interesse no desenvolvimento de uma nova geração de dispositivos ópticos e eletrônicos. A capacidade de formação de filmes finos de algumas dessas MOF as tornam materiais mais atraentes. A MOF bidimensional estudada neste trabalho foi a rede {[Zn(2,5-pdc)(H2O)2].H2O}n (2,5-pdc = 2,5-piridinodicarboxilato), ZnPDC2D. A MOF 2D foi sintetizada e caracterizada por diferentes técnicas experimentais e também foi estudada por simulação computacional. O modelo do ZnPDC2D foi otimizado por dois métodos (PBE e PBE-D2), os quais descreveram bem os parâmetros estruturais. A partir do modelo do ZnPDC2D, foi elaborada uma proposta para o processo de desidratação e assim, sugerindo a formação de três novas fases (d1-ZnPDC2D, d2-ZnPDC2D e d3-ZnPDC2D). A temperatura em que o ZnPDC2D sofre amorfização foi determinada através da medida de difração de raios X com aumento de temperatura in situ e pôdese inferir que a fase amorfa sofre uma transformação reversível após ser exposta ao ambiente. A termodinâmica da primeira etapa da desidratação mostra que o funcional PBE é mais adequado para descrever a espontaneidade da reação. Esperase obter as estruturas por meio de análises de difração de raios X por policritais e refinamento pelo método de Rietveld. O trabalho também reporta a simulação da energia de formação do monofilme pelos métodos PBE e PBE-D2. As análises de propriedades eletrônicas para todas as estruturas citadas foram executadas e discutidas conforme os processos e mudanças envolvidas.

The twodimensional MOF studied in this work was the network {[Zn(2,5-pdc)(H2O)2].H2O}n (2,5-pdc = 2,5-pyridinedicarboxylate), ZnPDC2D. The MOF 2D was synthesized and characterized by different experimental techniques and was also studied by computer simulation. Two optimized ZnPDC2D structures were obtained by distinct methods (PBE and PBE-D2) with a good description of their parameters. The structure obtained from the simulation of the dehydration process suggest the formation of three new phases (d1-ZnPDC2D, d2-ZnPDC2D and d3-ZnPDC2D). The temperature at which ZnPDC2D undergoes amorphization was determined by Xray podwer diffraction measurement with in situ temperature rise and it could be inferred that the amorphous phase undergoes a reversible transformation after being exposed to the environment. The thermodynamics of the first stage of dehydration shows that the PBE functional is adequate to describe the spontaneity of the reaction. The structures are expected to be obtained by Xray podwer diffraction analysis and refinement by the Rietveld method. Thise work also reports the simulation of the monofilm by the PBE and PBE-D2 methods. The analyses of electronic properties for all th cited structures were performed and discussed according to the processes and changes involved.

Der volle Inhalt der QuelleThis work focus the interection of Local Productive Systems (LPSs) and global productive chains, in order to identify the impacts to local productive struture from the differents forms of firms market access. Thus, endogenous and exogenous elements from LPSs were analyzed. To understand this phenomenom were analyzed the development path (strategic, products, technologies choices and organization structure) and the capacity (knowledge, abilities, practices and routines) acquired by firms with the time by, and were considerated the organization and action of local and non-local agents. The survey had been done with firms and organisms from furniture industry in two brasilian LPSs: Bento Gonçalves (RS) and São Bento do Sul (SC). Both locations were choseen because they are important to the furniture production and exportation, and they had differents development paths. Firms from LPS that commercialize their products with differents forms, present heterogeneous prodctive struture, and develop a large range of capacities. The supportive organisms develop differents projects to support the firms. Firms form LPS that mainly exports their products through export agents, have homogeneous productive struture and the development of capacities are centered in productive areas. Thus, the organisms do not act with deliberate joint action.Therefore, non local agents influence directaly the competitiveness of firms and limitate local development

Doctoral thesis, Universidad de Murcia, 2014. http://hdl.handle.net/10803/146180.
Der volle Inhalt der QuelleThis Doctoral Thesis aims to analyze the effectiveness of the management of the human capital in family firm. It is tested the effects in terms of results of the design (more or less formalized) and orientation (more or less economic) of the main practices of human resources (selection, training and compensation will be considered jointly and individually) in the context of a higher or lower coincidence of interests of ownership and management and the possible problems related to the predominance of the family and/or firm dimension. About the theoretical perspectives of the agency and preservation of the socioemotional wealth, they both constitute the framework in which the relations between the practices of human resources and results are based. In order to analyze the effect of the design and orientation of the practices of human resources in the family firm, from these theoretical perspectives, three empirical-research manuscripts were developed using different samples of Spanish firms. The empirical evidences posed in this Doctoral Thesis allow us to conclude that the implementation of mechanisms of formal management of human capital may contribute to restrict the agency problems of the family firm, favoring the obtaining of economic objectives and, therefore, the improvement of the results of the firm. A formal and rigorous applying of the human resources practices requires of a professional attitude from the management bodies (top management team) and government bodies (owners and administration council) of the family firm. The implementation of rigorous and objective selection systems; training politics focused to the development of capabilities and also compensation structures related to the individual and collective efficiency, create positive synergic effects in the global of the employees of the family firm and have also as a consequence the improvement of the firm performance. These findings suggest that both the design and implementation of the formal and rigorous practices of human resources are an alternative desirable and needed for the survival and competitiveness of the family firm. In order to implement these practices, duly prepared managers (who belong, or not, to the family) are needed. These practices may contribute to avoid and limit those specific problems of asymmetric altruism which arise in family firms (nepotism, inequity, etc), without counteract the advantages aroused from the implementation of the members of the family who characterized these type of firms. Finally, this Doctoral Thesis also contributes, from a theoretical point of view, to the literature of family firms with certain contributions related with the theoretical perspectives used and also with the field of analysis applied. In this sense, we must point out that it is through the combination of the theoretical fields of agency and of preservation of socioemotional wealth that it was easier to explain and characterize better the relations between the effectiveness of the human resources practices, family involvement in the business and also the firm performance. In addition, it was taken into consideration the analysis of these questions through the top management team level of the family firm (up to date, mainly used in previous studies). It was also taken into account the effect of the practices of the human resources in the global of the employees (not senior managers) of the family firm.
Teichner, Noah. „Le “canned” vaudeville et la mise en conserve médiatique aux États-Unis, du phonographe au film sonore : étude média-archéologique des courts métrages Vitaphone au format son-sur-disque (1926-1930)“. Electronic Thesis or Diss., Paris 8, 2021. http://www.theses.fr/2021PA080071.
Der volle Inhalt der QuelleThis dissertation reads the discourses, practices, and materialities of filmic and phonographic vaudeville through the broader history of “canned” media. Warner Bros.’ short films produced with the sound-on-disc Vitaphone process play a central role in this study which covers a period ranging from the beginnings of the phonograph industry and the institutionalization of vaudeville in the late 19th century to the introduction of electroacoustic technology in film and sound media during the second half of the 1920s. After studying vaudeville’s infrastructure as a mass media institution and its aesthetic capacities as a medium, the neglected role of the term “canned” in media history is reconsidered through practices of early phonography and trade press discourses on “canned” music and “canned” vaudeville. This leads to a contextualization of filmic vaudeville within the media landscape of the 1920s—the decline of big-time vaudeville and the rise of stage presentations in movie theatres—and an analysis of Vitaphone shorts’ production, distribution, and reception. The material possibilities afforded by the Vitaphone sound-on-disc technology and multi-camera set-up are then outlined and examined in relation to debates regarding sound and image scale. These technical considerations lay the groundwork for an in-depth investigation of approaches to address and diegetisation in the restored Vitaphone shorts from 1926-1930. The films’ means of addressing the spectator and of representing both the audience and the space of performance are put in perspective through examples of phonographic vaudeville dating back to the turn of the 20th century

Esta pesquisa tem como tema as redes sociais e nela buscou-se compreender a importância do fenômeno das ferramentas de redes sociais virtuais (FRSVs) no processo de disseminação da informação em bibliotecas, por intermédio dos profissionais da informação, dos campi do Instituto Federal da Bahia (IFBA). O presente trabalho procurou responder ao seguinte problema: de que forma as redes sociais são utilizadas como instrumento de disseminação da informação pelos bibliotecários do Instituto Federal da Bahia? Foi levantado o pressuposto de que o uso das ferramentas tecnológicas, por parte dos bibliotecários, não atende ao processo de disseminação da informação, em função da ausência de estratégias adequadas e do pouco incentivo ao uso das redes sociais virtuais. Na metodologia utilizou-se como abordagem o estudo de caso de investigação exploratória, e de procedimento metodológico do tipo qualitativo, com análise do conteúdo de questionários. O sujeito da pesquisa é constituído por bibliotecários (as) dos oito campi do IFBA que utilizam ferramentas de redes sociais: Porto Seguro, Eunapólis, Camaçari, Paulo Afonso, Vitória da Conquista, Santo Amaro, Valença e Salvador. A intenção final é trazer novas contribuições nos serviços em redes na seara da biblioteconomia, bem como ajudar os servidores federais a disseminarem o uso das ferramentas sociais no ambiente institucional de forma mais adequada. Os principais resultados apontam para o uso do Facebook é divulgar informações e conteúdos e em seguida as interações profissional e que as principais barreiras e obstáculos enfrentados na implementação das redes sociais foram de ordem política, estrutural e de lógica de redes.
This research has as its theme the social networks and it is aimed to understand the importance of the phenomenon of virtual social networking tools in the process of dissemination of information in libraries, through information professionals, the campuses of the Federal Institute of Bahia (IFBA). This study sought to answer the following problem: how social networks are used as a tool for dissemination of information by the librarians of the Federal Institute of Bahia? The assumption that the use of technological tools on the part of librarians, disregarded the process of dissemination of information, the lack of an adequate policy to encourage the use of social networks was raised. Methodology was used as the case study approach to exploratory research and qualitative methodological procedure with content analysis of questionnaires. The research subject is composed of librarians (as) IFBA using social networking tools: Porto Seguro, Eunapólis, Paulo Afonso, Vitória da Conquista, Santo Amaro, Valença and Salvador. The ultimate intention is to contribute to provide new contribution in the network, to helping federal employees to disseminate the use of social tool in the institutional environment more appropriately. The main results point to the use of Facebook is to disseminate information and content and then the professional interactions. The main barriers faced and obstacles in the implementation of social networks were political, structural and logical networks.

Der volle Inhalt der QuelleThis thesis studies risk culture in the context of a multinational company. The explanation of the key concepts of risk culture is what helped us to define our research subject, which is still in its infancy. The concept is also difficult to research because it represents multiple ambiguities, we were however able to find a solution to that problem. To reduce the impact of the ambiguousness of the subject, we based our research on organizational theories, and we defined two organizational aspects: formal and informal. Therefore, we approach risk culture by formal and informal aspects and by its manageability. In order to answer to our research question, we adopt the methodology based on one case study. Indeed, our thesis studies one multinational Canadian company where we spent 18 months in the field at its headquarters. We performed 45 interviews with presidents, vice presidents and directors, additionally we participated in risk assessment workshops and we worked with multiple functions related to risk management activities. Our results emphasize that risk culture needs an equilibrium between formal and informal aspects. We also show two different ways how risk mangers influence risk culture creation inside the company. Our thesis encourages future research on risk culture and on the development of that research subject

This work aims to test if the use of Google Trends as an exogenous variable improves the prediction of the monthly data for Brazilian Formal Job Creation (CAGED) compared to a model that uses only the lags themselves. For the selection of the model was used the algorithm Autometrics and for model comparison the Model Confidence Set. In addition, the model that uses Google Trends data will be compared with some market analyst’s forecasts. The results show that the model the uses the Google data as an exogenous variable is superior to the model that only uses the lag itself. However, this model was not able to overcome the market analysts.

This thesis examines three gaps that have not been discussed in the literature. The gaps relate to the effects of internationalization on capital structure and ownership structure of multinational companies. Therefore, three essays about the effects of internationalization were prepared. The first essay examined the effects of entry modes on debt, the second the effects of internationalization in the forms of indebtedness and the third the effects of internationalization on the ownership structure. Data form domestic and multinational publicly traded companies in Latin America from 2007 to 2011 were assembled into panel data with test and control variables for each essay. The results of the first essay indicate that the entry modes are relevant to determine the debt level of multinational and complement the studies based on upstream-downstream hypothesis. It also showed that companies with equity entry modes tend to be more indebted in the total and long term than companies with non-equity entry modes, reinforcing explanations given by the static trade-off theory, and less indebted in the short term, urging agency and pecking order theories. The results of the second essay show that the degree of internationalization: (i) increases the debt level of almost all debts provided by financial agents (banks), as hypothesized upstream-downstream and reduce the debt provided by non-financial (trade-credit), as suggested by the theory of financial constraint, (ii) has no effect on debt maturity (iii) different than expected, does not increase debt via national development bank (encouraged loans), (iv) was relevant to change the composition of indebtedness of multinationals compared to domestic firms and (v) the entry modes on internationalization does not affect the composition of debt. In the third essay, the main finding result was that the most internationalized companies and equity entry mode have lower levels of ownership concentration. Another important result of the third essay was that there is an unexplored simultaneity in determining the level of internationalization and concentration of ownership. Both the results of the third essay are supported by the Resource Based View countering the traditional view of agency theory.
Esta tese analisa três lacunas que ainda não foram discutidas na literatura. As lacunas dizem respeito aos efeitos da internacionalização na estrutura de capital e de propriedade de empresas multinacionais. Para tanto, três ensaios sobre os efeitos da internacionalização foram elaborados. O primeiro analisou os efeitos dos modos de entrada sobre o endividamento; o segundo os efeitos da internacionalização nas formas de endividamento e o terceiro os efeitos da internacionalização na estrutura de propriedade. A partir de dados de empresas multinacionais e domésticas de capital aberto latino-americanas de 2007 a 2011, foram montados painéis de dados com variáveis de teste e controle para cada ensaio. Os resultados do primeiro ensaio apontam que os modos de entrada são relevantes para determinar o nível de endividamento das multinacionais e complementam os resultados de trabalhos baseados na hipótese upstream-downstream. Evidenciou-se também que empresas com modos de entrada patrimoniais tendem a ser mais endividadas no longo prazo e total que empresas com modos de entrada não-patrimoniais, reforçando explicações dadas pela teoria do static trade-off; e menos endividadas no curto prazo, reforçando as explicações das teorias da agência e pecking order. Os resultados do segundo ensaio apontam que o grau de internacionalização: (i) aumenta o nível de endividamento da quase totalidade das dívidas providas por agentes financeiros (bancos), conforme a hipótese upstream-downstream e diminuem as dívidas providas por agentes não-financeiros (trade-credit), conforme teoria da restrição financeira; (ii) não produz efeitos sobre a maturidade das dívidas (iii) diferente do que esperava, não aumenta endividamento via banco nacional de desenvolvimento (empréstimos incentivados), (iv) foi relevante para alterar a composição do endividamento das multinacionais se comparada às empresas domésticas e (v) a forma de entrada na internacionalização não afeta a composição de endividamento. No terceiro ensaio o principal resultado encontrado foi que as empresas mais internacionalizadas e com modo de entrada patrimonial têm menores níveis de concentração de propriedade. Outro importante resultado do terceiro ensaio foi de que há uma simultaneidade ainda não explorada em estudos anteriores na determinação do nível de internacionalização e da concentração de propriedade. Ambos os resultados do terceiro ensaio estão amparados pela Visão Baseada em Recursos contrapondo a visão tradicional da teoria da agência.

Der volle Inhalt der QuelleEsta tese estuda o papel da tensão interfacial em filmes heterogêneos na modificação do magnetismo de camadas ferromagnéticas finas por meio do efeito magnetoestritivo inverso, definido como a mudança de magnetização produzida em materiais ferromagnéticos por um estresse externo. Tecnologicamente, isto visa ter um grau de controle magnético do material sem a aplicação de um campo externo, usando heteroestruturas compostas por uma camada não magnética caracterizada por uma transição de fase estrutural acionada pela temperatura, acoplada a uma camada ferromagnética. Em tais heteroestruturas, a magnetização da camada ferromagnética é modificada através de alterações no campo de tensão na interface quando a transição de fase estrutural na camada não magnética (atuador) é realizada. Assim, utilizamos a liga com memória de forma NiTi como atuador, para modificar o comportamento magnético de filmes ferromagnéticos através do acoplamento magnetoelástico em novas heteroestruturas de NiTi/Ni e NiTi/Co. O NiTi, quando próximo à sua composição equiatômica, é uma liga com memória de forma que sofre uma transição de fase estrutural reversível com a temperatura, proporcionando tensão no filme ferromagnético. Escolhemos esta liga porque o NiTi apresenta uma grande tensão de recuperação com temperaturas de transição acima da temperatura ambiente, para filmes de NiTi ricos em Ti, o que é de interesse para aplicações tecnológicas das heteroestruturas. A microestrutura do NiTi é fundamental para favorecer a transição de fase estrutural e definir as suas características. Assim, uma extensa revisão de pesquisas anteriores sobre NiTi é detalhada nesta tese. Para garantir um grande estresse durante a transição estrutural do NiTi com a temperatura, o filme de NiTi deve estar próximo de sua composição equiatômica e ter espessura acima de 800 nm. Ambas as características foram confirmadas pelas análises de espectroscopia de retroespalhamento Rutherford. A estrutura cristalina e sua transição com a temperatura foram estudadas por medidas de difração de raios X. Medidas de magnetização e histerese em função da temperatura, com campo aplicado no plano dos filmes, realizadas em um magnetômetro SQUID, comprovaram a existência do acoplamento magnetoelástico, o qual se manifestou através de variações no momento magnético da camada ferromagnética. Essas mudanças de magnetização, observadas principalmente na heteroestrutura com Ni, torna-se a característica principal do acoplamento magnetoelástico nesses novos materiais.

Der volle Inhalt der QuelleThe 1950s and 1960s appear as two decades of intense effervescence in the field of Thai cinema. In the immediate aftermath of the Second World War, the adoption of the 16mm format by a new generation of filmmakers gave rise to a very popular cinematic production in the kingdom. Whereas the musicals directed by the pioneer founders of the Phaphayon Siang Si Krung company until 1941 seemed to promise the perennial hegemony of a real ‘Hollywood of Siam’, these joyously rhapsodic fictions, filmed with makeshift means and accompanied live by the legendary loquaciousness of professional dubbers, encountered a broad public from Bangkok to the most remote provincial villages, within a screening framework stemming directly from earlier mixed shows. Nevertheless, the accidental disappearance of the actor Mit Chaibancha on the 8th of October 1970, during the shooting of Insi thong [« The golden eagle »], put an abrupt end to this singularly belated experience of oral cinema. The recent composition of an archival fund at the Thai Film Archive permitted the bringing to light of rich vestiges from this well-named ‘16mm era’. This research is a first historiographical attempt to exhume this visual patrimony, both embedded in the Siamese dramatic tradition and generated in the context of a military dictatorship that came under the complexe influence of its American ally during these Cold War years
