This thesis analyzes Turkey&rsquo / s integration to European Patent System with special reference to the role of Small and Medium-Sized Enterprises (SMEs) within this process. The main purpose is to understand the position of SMEs in Turkey within the industrial property (IP) system in general, patent system in particular, as their effective usage of the IP system is crucial in terms of proper integration of Turkey into the European Patent System. In this respect, the thesis aims to answer two basic questions, namely, &ldquo / What is the role of SMEs within the process of Turkey&rsquo / s integration to European Patent System&rdquo / and &ldquo / How can a more effective use of patent system by the SMEs in Turkey be achieved?&rdquo / Within this framework, a field research was conducted in three different industrial areas in Ankara with 136 SMEs active in manufacturing industry. Within the scope of the field research, it was tried to measure the R&amp / D capacity as well as the extent to which the industrial property system, especially the patent system, in Turkey is effectively used by the participant firms. According to the results of the field research, some proposals were tried to be put forward in terms of the achievement of a more effective use of the industrial property system in general, patent system in particular, by the SMEs in Turkey.

This dissertation is concerned with how the social capital of corporate insiders is associated with the governance and performance of publicly listed small and medium- sized enterprises (SMEs) in Canada. The premise of social capital theory is that relationships matter and that network structures have implications for outcomes. Encouraging SME growth and performance is an important part of economic policy. In Canada, going public is one way innovative SMEs can access capital for growth. This research considers the network of relationships between directors, owners and senior officers in a public corporation – i.e. the social capital of corporate insiders – to better understand corporate governance. Family-run firms, large corporate ownership and professional relationships between directors have been the subject of numerous corporate governance studies. They can also be considered networks. In this research, I assume that these various networks act to unite corporate insiders into coalitions with similar interests. I consider the implications of social capital on firm performance in terms of effective control, director independence, CEO ownership, and family control of the firm. The hypotheses, generated from the theory of internal social capital of the firm, are tested using fixed and random effects regression models on a panel of Canadian industrial SMEs that had an initial public offering between 2000 and 2010. SME performance is measured by Tobin’s Q. I find support for the idea that the structure of social capital within the firm is related to corporate governance and associated with performance. My results indicate that having multiple coalitions in the firm, as well as more independent directors, are both positively associated with performance. There are also indirect effects related to the social capital of the firm. After controlling for the structure of social capital in the firm, CEO ownership is found to have no association with firm performance, except in a few cases where the CEO owns in excess of 40 percent of the firm. Once these cases are omitted from the sample there does not appear to be a significant relationship between CEO ownership and performance. These few cases suggest the role of CEO may be important to performance outcomes in highly controlled firms. Further case-study research into this finding may be merited. Finally, I find no evidence that family-run firms have valuations that differ from other firms. The theory of internal social capital of a firm contributes to the corporate gov- ernance literature by considering how the network of relationships within the firm affects outcomes. There are also useful methodological contributions from this re- search. Theoretically grounded network measures determine: (i) a scale of effective control of a firm when there are multiple coalitions of owners, and (ii) a way to iden- tify truly independent directors. Entrepreneurs, directors and managers will find this research useful because it outlines how the structure of relationships within an SME is associated with firm valuation.

This thesis is inspired by a persistent limitation in the use of composite biomaterials for orthopaedic applications, namely the agglomeration of reinforcing particles in these composites, which has resulted in poor mechanical properties. The use of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and hydroxyapatite (HA) nanoparticles to produce biodegradable nanocomposites is investigated. More specifically, the thesis investigates different methods of composite processing, and interfacial modifying agents and the effect that these have on the nano- and micro- scale structure of composites and their mechanical properties. PHBV and HA were chosen because PHBV is a biodegradable/biocompatible polymer and it has a relatively high stiffness when compared to other biodegradable polymers frequently used in orthopaedic applications. HA is chemically similar to ceramic phase found in bones and hard tissues and the inclusion of HA into biomedical materials has been shown to enhance the rate of osteoconduction. HA/PHBV composites were produced using different dispersing agents including poly(acrylic acid) (PAA), a model dispersing agent, polyethyleneimine (PEI) which allowed for the development of a single solvent system for composite preparation, and heparin (Hep), a macromolecule which is produced in vivo. Additionally, HA/PAA/PHBV composites were prepared from both sonicated and non-sonicated HA/PAA suspensions up to approximately 17% by weight (wt %) of HA content. Attempts to prepare composites with higher HA loadings led to inhomogeneous composite mixtures, which were caused by the dual solvent system used for the composite preparation. The HA/PEI/PHBV and HA/Hep/PHBV composites were produced up to approximately 75 wt % of HA content. It was found that the HA/PEI/PHBV and HA/Hep/PHBV composites could be prepared at higher loadings than HA/PAA/PHBV composites due to the single solvent system used for the preparation of the HA/PEI/PHBV composites and the better dispersion of HA/Hep particles in precursor suspensions. Finally, selected HA/PEI/PHBV composites were further processed using a twin screw extruder. All of the composites were characterised in terms of their dispersion levels as well as their compressive mechanical properties. In addition, HA/PEI/PHBV composite reinforced with 20 wt % of HA content was also tested for its mechanical properties using three different test types; compression, three-point bending, and tensile tests. Finally, the HA/PAA/PHBV, HA/PEI/PHBV, and HA/Hep/PHBV composites were tested their compressive mechanical properties in wet state. It was found that the sonicated HA/PAA suspensions in general had better colloidal stability than non-sonicated ones and that this yielded composites with superior compressive moduli than those prepared from non-sonicated suspensions. In addition, the better dispersion of the particles in the composites prepared from the sonicated suspensions, as confirmed by transmission electron microscopic (TEM) images, led to higher percentage crystallinities when compared to the composites prepared from non-sonicated suspensions. It is likely that the greater number of individual HA particles and smaller HA agglomerates observed in the composites prepared from sonication treatment are acting as nuclei for crystal growth more effectively than large HA agglomerates. The largest modulus and yield strength that could be achieved with this system were approximately 1.45 GPa and 80 MPa, respectively. Composites of HA/PEI/PHBV and HA/Hep/PHBV with approximately 55 wt % of HA content were found to exhibit the largest compressive moduli of approximately 2.5 and 2.8 GPa, respectively. Moreover, the yield strengths for the same materials were found to be approximately 123 and 120 MPa, respectively. This was found to correlate with the better levels of dispersion within the nanocomposites that could be achieved using these stabilisers. The extruded samples were found to have an even greater degree of particle dispersion when compared to the unextruded ones. This improved degree of particle dispersion of the extruded samples resulted in higher moduli in comparison to unextruded samples. The largest compressive modulus and yield strength of the extruded samples were found to be approximately 3.2 GPa and 125 MPa, respectively. The compressive moduli of the composites produced in this thesis are significantly greater than that of cancellous bone (0.4 GPa), but significantly lower than that of cortical bone (12.8–17.7 GPa). However, maximum yield strengths of the HA/PEI/PHBV and HA/Hep/PHBV composites match to cortical bone (120–180 MPa), which is a noteworthy finding in this thesis. The wet mechanical results of all composites as well as pure PHBV polymer showed a reduction in both moduli and yield strengths when compared to dry state. In addition, after 2 weeks in wet state both moduli and yield strengths of the composites and pure polymer converged to approximately the same values. Finally, the HA/PEI/PHBV composite samples tested by tensile testing showed the highest Young’s modulus and those tested by compression testing possessed the lowest Young’s modulus. This resulted from the difference in periods of time for heating exposure and void contents of the tested samples, which were prepared by different methods. However, toughness values obtained from the samples tested using three-point bending and tensile tests, was not significantly different.

Thesis (MScEng (Industrial Engineering))--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: South Africa has potential to grow extensively as a country supplying components to the global aerospace industry supply chains, as well as directly to OEMs like Airbus, Boeing and Cessna which are first tier suppliers. The economic crisis had a significant impact on the growth of small to medium sized enterprises (SMEs), also in aerospace companies. Before the recession, SMEs did not see the necessity to become certified with internationally accredited quality standards, because there were an abundance of business opportunities. In the current restricted business climate SMEs are increasingly realising the importance of certification. The standard that aerospace companies need to comply with, is the AS 9100 standard. Compliance to AS 9100 was previously considered as a competitive advantage (order winner) but has become a necessary prerequisite (order qualifier) to be considered for a contract. In the aerospace industry accountability, traceability, documentation and quality of parts are of critical importance. Quality of products according to specification is crucial as it has a profound effect on safety. The tendency in improving of a company's processes is to scale down on superfluous documentation. In the case of aerospace companies, this is an extremely challenging goal because traceability is of such crucial importance in this sector in terms of aircraft structural system and –operational integrity. For the purpose of this study, a small to medium manufacturer of aircraft and defence system parts was studied and considered to be representative of the aerospace industry in South Africa. The research gap amongst SMEs was investigated by means of a case study at an SME in South Africa where an IT-based AS 9100 quality management system was designed, developed and implemented. The investigation includes the analysis of the research partner's quality documents, the steps in the design and development of the quality management system (QMS) and a description of the implementation thereof. This study aims to provide the focus group (SMEs) with more knowledge when developing their quality management systems for implementation of the AS 9100 requirement to compete in the aerospace industry. It describes the historic background and current use of the AS 9100 standard as background. The objective of the case study will be to determine the generic validity of the method to be able to implement AS 9100 at a small to medium sized aerospace supplier when using the same guidelines which are followed in this specific case. The method's value and success are determined by means of an external audit (certification audit) of the company used in the case study. The method makes specific use of an IT-based infrastructure to facilitate the reduction of unnecessary documentation. Experiences gained by the author in applying AS 9100 to upgrade local manufacturing companies to aerospace suppliers to Volvo Aero Company in Sweden are briefly discussed as well as the validity to make use of these generic steps. / AFRIKAANSE OPSOMMING: Suid-Afrika het die potensiaal om betekenisvol te groei as ʼn land wat komponente lewer aan internasionale lugvaart verskaffersnetwerke. Die ekonomiese krisis het 'n beduidende impak op die groei van klein tot mediumgrootte ondernemings gehad, asook in die lugvaart-industrie. Voor die resessie, het hierdie ondernemings nie die noodsaaklikheid om akkreditasie tot internasionale kwaliteitstandaarde te verkry na waarde geag nie, weens die genoegsame beskikbaarheid van sakegeleenthede. In die huidige ekonomiese klimaat word die belangrikheid van akkreditasie egter toenemend besef. Die standaard waaraan maatskappye in die lugvaartindustrie moet voldoen is die AS 9100 kwaliteitsbeheerstelsel. Voorheen is die akkreditasie tot hierdie standaard gesien as ʼn mededingende voordeel wanneer daar getender is vir ʼn kontrak. Deesdae word dit as ʼn noodsaaklike voorvereiste beskou, voordat die besigheid se aansoek om ʼn kontrak te verkry eers oorweeg sal word. In die lugvaartnywerheid is aanspreeklikheid, naspeurbaarheid en dokumentasie van kardinale belang. Die tendens in die verbetering van 'n maatskappy se prosesse is om af te skaal ten opsigte van onnodige dokumentasie. In die geval van lug- en ruimtevaartmaatskappye, is dit 'n uiters uitdagende doel, omdat naspeurbaarheid gedurende die komponent se leeftyd van deurslaggewende belang is in hierdie sektor. Vir die doel van hierdie studie is 'n klein- tot mediumgrootte vervaardiger van lugvaartkomponente wat dien as navorsingsvennoot, bestudeer. Hulle is beskou as verteenwoordigend van die lugvaartnywerheid in Suid-Afrika vir die doel van die studie. Die navorsingsgaping is geïdentifiseer as die implementering van ʼn gehaltebeheer stelsel wat voldoen aan die AS 9100 kwaliteitsbeheer standaard. Die gevallestudie van hierdie lugvaartvervaardiger sluit die bestudering van die ontwerp, ontwikkeling en implementering van ʼn IT-gebaseerde AS 9100 gehaltestelsel in. In die studie word die navorsingsvennoot se kwaliteitstelsel en dokumente ontleed, en die stappe in die ontwerp en ontwikkeling van die nuwe stelsel verduidelik. Die implementering en die validering van die stelsel deur die outeur, word beskryf en getoets deur middel van ʼn eksterne sertifiseringsliggaam. Hierdie studie poog om as riglyn te dien vir die fokus groep (klein- tot mediumgrootte ondernemings) en hul kennis van die AS 9100 standaard te verbreed. Hierdie kennis dra potensieel by tot die ontwikkeling van hul eie gehaltebestuur stelsels en die implementering van AS 9100 vereistes sodat akkreditasie tot die standaard verkry kan word en hul die lugvaartnywerheid kan betree. Die dokument beskryf die historiese agtergrond en huidige gebruik van die AS 9100 standaard. Die doel van die gevallestudie is om die generiese waarde van die metode vas te stel sodat ander klein tot mediumgrootte ondernemings in staat sal wees om dieselfde metode te volg om AS 9100 te implementeer. Die metode se geldigheid en sukses word bepaal deur middel van 'n eksterne oudit (sertifiseringsoudit) van die navorsingsvennoot in die gevallestudie. Die metode maak gebruik van 'n spesifieke IT-gebaseerde infrastruktuur om die vermindering van onnodige dokumentasie te fasiliteer. Ervarings en bevindings van ʼn soortgelyke studie in Swede, waar die outeur lid van die implementeringspan was, word ook kortliks bespreek om die geldigheid van die generiese stappe te bepaal en te beklemtoon.

This thesis explores the scope for the transfer and integration of human resources management (HRM) knowledge to provide the basis for the development of more productive and efficient supply chains, in the specific case of the aftermarket distribution channels of multinational companies in the automotive industry in China. Most studies of human resources management, supply chain management, and knowledge transfer have focused on internal transfer within multinational companies and there has been more limited research on the transfer of such knowledge across organisations in the supply chain, particularly in relation to distribution channels. Thus the starting point for the research was to understand the preconditions, mechanisms and effects on the distribution supply chain of the transfer and integration of HRM knowledge. To explore these issues the thesis compares and contrasts a poorly performing supply chain (that is Company J's supply chain) with two more successful supply chains in the automotive aftersales market (that is those of Company M and Company S). The aim was to identify whether the poorly performing supply chain could learn from the other two cases through a detailed exploration of the motivators and mediators that facilitate or hinder processes of HRM transfer and integration, and the outcomes of these processes on the performance of the supply chains and the manufacturers and distributors within the supply chains. A qualitative research approach was utilised. Data was gathered through one-on-one, semi-structured interviews with senior-level management, mid-level management, and frontline staff from the manufacturers and wholesale distributors in the three automotive aftermarket distribution channels and analysed using computer-assisted coding software, NVivo. In line with the extant literature, the thesis findings support the proposition that a relational supply chain network based on trust facilitates HRM knowledge transfer and integration, and provides a basis for competitive advantage in the supply chain. At the same time the findings suggest some important extensions to current knowledge and understanding of the processes and impact of HRM knowledge transfer. Firstly the research found that consideration should be given to recategorising the classic division between tacit and explicit knowledge with respect to HRM into fundamental and differential categories, in order to more clearly differentiate the type of strategic HRM knowledge transfer that could provide the basis for competitive advantage. Likewise the study found that it is not the mechanism of transfer- whether through systems or by inter-person channels- that should be the criteria to categorise knowledge, as a blended approach involving both types of transfer mechanisms was associated with better transfer effectiveness. Third the type of HRM to be transferred needs to fit the specific needs of distributors within the supply chain; in practice the best fit for this part of the supply chain can be considered a mix of paternalistic and transaction HRM, rather than the so-called 'best' practice HRM. Finally although there was potential in principle for the underperforming supply chain to learn from the experiences and practices of the higher performing supply chains, the extent to which Company J was likely to be able to emulate the more successful chains was constrained by significant internal barriers to learning (for example the pressure for short-term gains and the time needed to build trust, the lack of internal HRM expertise and the lack of local decision-making authority). However, an even more major constraint on the learning process came from the dynamic changes in the aftermarket distribution system that had the potential even to disrupt the trust-based partnerships in the exemplar supply chains. Thus the scope for applying the lessons from past practice, which has been the major focus of the comparative investigation of the three supply chains, may be limited by both the variations in internal conditions and by the fact that the key challenges for future development may be different from those faced in the automotive aftersales market in the past.

A redefinição da centralidade é um dos componentes da metamorfose da cidade e do urbano na contemporaneidade. Embora nas metrópoles brasileiras a ocorrência desse fenômeno seja evidente, estudos recentes têm revelado indícios de seu aparecimento também nas cidades médias do país. A presente dissertação, nesse sentido, propõe-se a compreender uma das facetas da transformação na centralidade intraurbana de uma cidade média localizada na região central do território gaúcho. Busca-se, mais especificamente, o entendimento do processo de descentralização do setor terciário em Santa Maria/RS, o qual tem conformado duas aglomerações comerciais e de prestação de serviços em dois bairros distantes do Centro Principal dessa cidade. Para isso, a análise foi desenvolvida em dois planos. Primeiramente, faz-se uma abordagem espaço-temporal da expansão urbana de Santa Maria destacando os principais agentes e variáveis geradores do processo de descentralização, responsáveis pela formação dos prováveis subcentros na cidade em questão. Já no segundo plano da análise, é realizada a caracterização dos novos centros com a finalidade de revelar as suas funções e configurações espaciais, bem como as relações entre tais espaços de consumo e a população que os utiliza e os fatores locacionais que levaram os empresários a investirem nos referidos locais. Essas duas dimensões analíticas, ainda que distintas, apresentam complementariedade: enquanto uma desenvolve o estudo com ênfase no interior dos bairros, a outra integra tais bairros à cidade sob uma perspectiva histórica, com a finalidade de elucidar o presente. A importância do estudo das transformações no âmbito da centralidade intraurbana se assenta no fato de esta ser uma das tendências da urbanização contemporânea e, ainda, por estar relacionada ao debate acerca do desenvolvimento socioespacial urbano. Ademais, ao se ter em vista que algumas cidades médias brasileiras apontam indícios da ocorrência desse fenômeno, torna-se urgente seu entendimento levando em consideração as singularidades dessas cidades. / The redefinition of centrality is one of the components of the metamorphosis of the contemporary city and the urban space. Although the occurrence of this phenomenon is evident in the Brazilian metropolis, recent studies have revealed evidence of its appearance also in medium-sized cities in the country. This dissertation proposed to understand one of the facets of transformation in the intraurban centrality of a medium-sized city in the central region of the gaucho territory. More specifically, it seeks to understand the decentralization process of the tertiary sector in Santa Maria/RS, which has formed two commercial and services agglomeration in two neighborhoods which are quite far from the main center of this city. For this, the analysis was performed in two stages. First, there is a spatio-temporal approach to the urban expansion of Santa Maria, highlighting the agents and variables generators of the decentralization process, responsible for the formation of the sub-centers in this city. In the second stage of this analysis, the characterization of the new centers is performed in order to reveal their functions and spatial configurations, as well as the relationship between such spaces and the population that uses them and locational factors that led entrepreneurs to invest in these locations. Although these two analytical dimensions are different, they present complementarities: while one of them develops a study focusing on the inside of the neighborhoods, the other one integrates such neighborhoods in the city under a historical perspective, for the purpose of elucidating the present. The importance of the study of changes in the scope of intra-urban centrality is based on the fact that this is one of the trends of contemporary urbanization and also because it is related to the debate on urban social and spatial development. Moreover, knowing that some medium-sized Brazilian cities show evidence of the occurrence of this phenomenon, its understanding has become urgent, taking into account the peculiarities of these cities.

The objective of this study is to find out how and why Small to Medium sized Enterprises (SME’s) practice ecodesign. This problem is investigated by conducting seven qualitative interviews with spokesmen from ecodesigning SME’s in The Netherlands. The motivations for the researched SME’s to practice ecodesign are that there are new business opportunities, that it improves the corporate image, that they have a desire to change production to benefit the environment, and out of (expected) governmental legislation. In this thesis it was found that the researched SME’s get their knowledge to ensure that their products are sustainable firstly from their employees. They also apply the method of trial and error, they consult scientific publications, suppliers, and on sustainability events. The Life Cycle Assessment was the only scientific method or tool that was used by the businesses of the respondents. The benefits of practicing ecodesign for the SME’s are that the demand for ecodesigned products is growing, that it improves the corporate image of the company, that it improves business to business relations, that it increases the loyalty of employees to their businesses through working on values that are important to them, and that it provides a new base for innovative ideas. Obstacles to practicing ecodesign seem to be that trade-offs have to be made and that consumers perceive that the ecodesigned products are overpriced.
