Internationalisation process & upgrading prospects of Indian garment manufacturers

Patel, Sheetal Anil January 2011 (has links)
In the context of globalisation and liberalising economies, an increasing number of local firms based in developing countries and emerging markets are encouraged to internationalise their business activities and thus participate in foreign trade. Their sustained success is founded on two key factors; their ability to access potential foreign markets, and their ability to upgrade their capabilities and thus improve their positioning in global markets. This thesis investigates the internationalisation process and upgrading prospects of Indian Garment Manufacturers (IGMs). It begins by examining how IGMs gain access to foreign markets and discusses the factors that help or hinder their progress. The thesis subsequently explores the ways in which IGMs upgrade their activities to higher value-added activities and investigates the contributory factors that drive and shape their upgrading prospects. Existing studies employ the concept of ‘Diaspora networks’ or ethnic ties to explain how local firms from emerging markets are able to internationalise their business activities. These studies highlight the integral role played by Diaspora networks in enabling this internationalisation. Diaspora networks help connect local firms with foreign, world class buyers (or ‘lead firms’) using the Diaspora’s own pre-established ties and links with such lead firms. Similarly, Global Value Chain (GVC) proponents assume the upgrading prospects of these local firms can be enhanced as a result of linking up with ‘lead firms’ because of the benefits that can be derived from knowledge and technology transfer imparted through working with world class buyers. The extant literature however is vague on the internationalisation processes of IGMs. Furthermore, it does not adequately address the extent to which IGMs utilise Indian Diaspora networks to access foreign markets and to internationalise their business activities. It is also unclear what mechanisms are employed to impart knowledge from lead buyers to suppliers and to what extent the knowledge and technology transferred plays a key role in progressing IGMs upgrading activities; especially in the higher value added functions of design. This thesis contributes by addressing and shedding further light on these unresolved issues. It examines the issues using a combined approach, where theories and concepts from international business (IB) and GVC are employed in analysing the subject matter and thus allows for a more nuanced and comprehensive understanding of the issues under investigation. To explore the above themes a case study based approach was employed. Interviews were conducted with key decision makers/owners of 23 case companies. Further interviews with key industry, academic and government heads were conducted as a means of triangulation. Interviews were, in turn, supplemented with documentary evidence and published material from company websites, industry and academic journals, and newspaper articles, so as to arrive at a more comprehensive understanding of the issues in question. Findings from this study suggest that IGMs rarely use Diaspora networks to access foreign markets. Instead, the majority of IGMs have achieved internationalisation as a result of well-developed networks of formal intermediaries based in India who have facilitated connections with prospective buyers. Furthermore, their manner of internationalisation reveals IGMs tend to access foreign markets initially at a very young age and at a rapid pace. Thus process-based theories of internationalisation seem inappropriate in explaining this rapid pace of internationalisation; insights from the literature on Born Globals and International New Ventures (INVs) seem, at first, to offer better explanations. However, employing concepts such as the ‘mature’ born global and the ‘failed’ born global leads one to re-examine and reconsider these initial findings. Re-examined findings indicate that in fact maturing IGMs are realigning their internationalisation trajectories to be better positioned to take advantage of favourable domestic market conditions. These findings are better explained using a more inclusive definition of internationalisation; particularly, concepts of de-internationalisation and extra-regional expansion from the field of IB. Additional findings, related to the issue of upgrading, indicate that contextual factors, usually related to the domestic economy and the firm’s internal circumstances, play a significant role in affecting the upgrading prospects of IGMs. These findings are contrary to GVC-based explanations of what drives and shapes IGMs’ upgrading activities, which place excessive emphasis on the role of the ‘lead firm’. In particular, GVC-based assumptions regarding the knowledge and technology transfer benefits available to local manufacturers by linking with larger world class buyers or lead firms seem of limited applicability to IGMs; here, firm-specific factors seem more important in determining firm choices concerning upgrading trajectories.

A Mobile Agent Based Service Architecture for Internet Telephony

Glitho, Roch H. January 2002 (has links)
Internet Telephony defined as real time voice or multimediacommunications over packet switched networks dates back to theearly days of the Internet. ARPA's Network SecureCommunications project had implemented, as early as December1973, an infrastructure for local and transnet real time voicecommunication. Two main sets of standards have emerged: H. 323from the ITU-T and the session initiation protocol (SIP) fromthe Internet Engineering Task Force (IETF). Both includespecifications for value added services. Value added services,or more simply services, are critical to service providers'survival and success. Unfortunately, the service architecturesthat come with the ITU-T and the IETF sets of standards arerather weak. Although they are constantly evolving,alternatives and complements need to be researched. This thesiswhich is made up of a formal dissertation and 6 appendices,proposes a novel mobile agent based service architecture forInternet Telephony. The architecture addresses the issues noneof the existing architectures solves in a satisfactory manner.Furthermore it adds mobile agents to the panoply of servicecreation tools. The appendices are reprints of articlespublished in refereed magazines/journals or under considerationfor publication. The formal dissertation is a summary of thepublications. A consistent and comprehensive set ofrequirements are derived. They are TINA-C flavored, but adaptedto Internet Telephony. They are used to critically reviewrelated work and also used to motivate the use of mobile agentsas the pillars of a novel architecture. The components of thisnovel architecture are identified. The key component is themobile service agent. It acts as a folder and carriesservice(s) to which the end-user has subscribed. Mobile serviceagents need to be upgraded when new versions of service logicare available and when end-users make changes to service data.This thesis proposes a novel upgrading framework. The currentInternet infrastructure comprises a wide range of hosts. Mobileagent platforms are now available for most of thesehosts/clients including memory/processing power constrainedPDAs. Our mobile service agents need to adapt to hostvariability when roaming. A novel adaptivity framework is alsoproposed. These two frameworks are general and can be appliedto any other mobile agent which meets a basic set ofassumptions. A key advantage of a mobile agent based servicearchitecture is that it enables the developement of mobileagent based services. The thesis proposes a novel mobile agentbased multi-party session scheduler. The feasibility and theadvantages of the architecture proposed by this thesis havebeen demonstrated by a prototype on which measurements havebeen made. Future work includes the addition of a securityframework to the architecture, and refinenements to theupgrading and adaptivity frameworks. More mobile agent basedservices, especially mobile multi agent based services willalso be developed. / <p>NR 20140805</p>

Rening av amin i biogasproduktion : En studie med syfte att undersöka om det går att optimera företaget Puregas Solutions AB uppgraderingsanläggningar för biogas med hjälp av olika reningsfilter samt undersöka hur dessa filter underhålls.

Nyström, André, Vilör, Jakob January 2017 (has links)
Abstrakt   Det förnyelsebara bränslet biogas har fått mer och mer intresse runt om i världen, men för att biogasen ska gå att använda som fordonsbränsle måste den först uppgraderas. I den processen separeras kolväten och andra föroreningar för att metanhalten ska ökas och därmed kommer biogasen att bli optimal för användning i förbränningsmotorer (Enefalk och Ersöz 2016).   Syfte med det här arbetet var att undersöka hur bra olika filter kan fungera för att ta bort orenheter från aminen i Puregas Solutions AB anläggningar. När undersökning av olika filter var gjord studerades underhållet för dessa filter. Experimentet utfördes i Puregas Solutions AB verkstad. Där användes ett aminprov från deras anläggning i Sverige för att den var extremt förorenad och därmed var det lättare att se hur bra de olika filtren filtrerar föroreningar.   Efter att mottagit provsvaren från DOW Chemical Company sammanställdes analyserna. Provsvaren visade på att de testade filtren inte tog bort orenheter från aminen. / Abstract   Renewable biogas fuel has become increasingly interesting around the world, however before biogas is used as fuel in vehicles it must first be upgraded. During that process the hydrocarbons and other pollutions are separated to increase the concentration of methane and make the biogas better suited for combustion engines (Enefalk and Ersöz 2016).   The purpose of this study was to examine how efficiently different filters can remove impurities from amine at Puregas Solutions AB upgrading plant. After the investigation of the different filters was completed we wanted to further study the maintenance of the filters. Experiments were performed at Puregas Solutions AB workshop, where the amine samples from their plant in Sweden were used to see how well the various filters performed.   After receiving the test results from Dow Chemical Company, the results were compiled and they showed that the tested filters did not remove impurities from the amine.

SMEs and Social Upgrading in Developing Countries : Doing Good or Evading Responsibilities?

Olofsson, Johanna, Guselin, Isabelle January 2016 (has links)
Workers in labour-intensive industries in developing countries have been described as the ‘hidden hands’ in the making of valuable goods in global production networks (GPNs). The process of improving the rights and entitlements of workers in GPNs have been referred to as ’social upgrading’. However, literature on social upgrading has tended to overlook the role of small and medium-sized enterprises (SMEs), and there is still little scientific understanding of how small businesses in developing countries can engage in social upgrading. The aim of this thesis is to enhance the understanding of how SMEs in developing countries can improve working conditions and labour rights. Through a qualitative case study, this study goes beyond statements of leading Fair Trade brands to provide insights based on voices of both workers and owner-managers in a small garment factory in Nepal. This study brings forward observations where SMEs, shaped by their characteristics, are enabled to evade responsibilities concerning working conditions and labour rights.

Uppgradering av kretsscheman i en HVDC-station / Upgrading of circuit diagrams in a HVDC-station

Lundstedt, Daniel, Nordqvist, Henrik January 2016 (has links)
Detta examensarbete är gjort på uppdrag av ABB i Ludvika. ABB har fått en beställning på en uppgradering av en högspänd likströmstation, på engelska High Voltage Direct Current (HVDC). Det finns huvudsakligen två olika tekniker gällande HVDC. Det är HVDC med Line Commutated Converters (LCC) och HVDC med Voltage Source Converters (VSC). LCC-tekniken är den äldsta och mest använda tekniken och är den teknik som stationen som uppgraderas använder. VSC-HVDC är en något nyare teknik som har fördelen att den inte kräver ett genererande nät på båda sidor av HVDC-länken men nackdelen att den inte klarar av lika höga effekter som LCC gör. Den har med dessa egenskaper blivit en populär teknik att använda för att till exempel överföra energi från vindkraftsparker ute till havs in till fastlandet eller för att förse oljeplattformar med energi. VSC-tekniken introducerades för första gången 1997 av ABB där den går under namnet HVDC-Light. Den aktuella HVDC-länken är en förbindelse mellan två länder och har en överföringskapacitet på totalt 600 MW. Uppgraderingen innefattar även uppdatering av befintliga scheman för att de skall finnas tillgängliga i den nya programvaran Engineering Base. Ritningarna har ritats i Microsoft Visio. Den utrustning som har ritats om och behandlas i denna rapport gäller utrustningen på likströmssidan av HVDC-stationen. Det innefattar jordknivar, frånskiljare, strömtransformatorer, spänningsdelare, överströmsskydd och genomföringar. / This thesis was conducted on behalf of ABB in Ludvika. ABB has received an order for an upgrade of a high voltage direct current (HVDC) station. There are two main technologies that HVDC is based on; line commutated converters (LCC) and voltage source converters (VSC). The LCC technology is the oldest and most widely used. It's also the technology that the upgraded station is based on. VSC HVDC is a newer technology that has the advantage of not requiring a generating power grid on both sides of the HVDC link but has the disadvantage that it cannot handle as high power as LCC can. With these qualities it has become a popular technology to use to transfer energy from offshore wind farms to the mainland or to provide oil platforms with energy. VSC technology was first introduced in 1997 by ABB where it is called HVDC Light. The revised HVDC link is a connection between two countries and has a total power transmission of 600 MW. The upgrade also includes updating existing circuit diagrams for the HVDC station to be available in the new software Engineering Base. The circuit diagrams have been drawn in Microsoft Visio. The equipment which have been designed and examined in this report applies to equipment on the DC side of the HVDC station. This includes grounding knives, disconnectors, power transformers, voltage dividers, current protection units and wall bushings.

Empowerment of Women through a Colourful slum-project : A case of the slum-upgrading project in Kampung Tridi of Indonesia

Arvidsson, Christina January 2019 (has links)
This study aims to evaluate if a slum-upgrading project in 2016 in Malang, Indonesia lead to empowerment of the women living in the neighbourhood. The study uses the concept of Empowerment by Naila Kabeer as a theoretical lens and focuses on women’s resources, agency and achievement after the project was carried out. The study was conducted as a Minor Field Study, which relied mainly on semi-structured interviews, which were complemented with personal observation. The respondents were selected purposively: meaning only those who participated in the painting project. The study findings are limited to the case explored and do not thus aim to a generalization on other projects in Indonesia. Findings are however informative for similar projects in similar contexts. The findings indicate that women were initially excluded from official decision-making during the project. In spite of this, however, the project enabled women to be more active in the economy to organize their own meetings and become responsible for the communal cleaning and events in the area. This participation led women to also have more to say in the community and they have been able to increase their savings and set goals for their families and children, which was impossible before the existence of the slum-upgrading in the area.

O que o Complexo do Alemão nos conta sobre as cidades: poder e conhecimento no Rio de Janeiro no início dos anos 80 / What the Complexo do Alemão tell us about city: power and knowledge in Rio de Janeiro in early 1980s

Matiolli, Thiago Oliveira Lima 16 August 2016 (has links)
Esse trabalho analisa as condições que tornaram possível, e aceitável, a percepção de que favelas diferentes, mas contíguas entre si, fossem apreendidas como uma unidade territorial nomeada do Complexo do Alemão. Tal perspectiva remete a fins da década de 1970 e início dos anos 1980, período reconhecido pela literatura urbana carioca como aquele no qual a solução para o problema da favela, por parte do poder público, passa a ser um conjunto de intervenções diversas, às quais se convencionou nomear de urbanização, em detrimento da política de remoção. Dentre outros elementos, essa reorientação da ação governamental, por um lado, vai desencadear uma abundante produção de informações sobre esses territórios, através da montagem de um quadro técnico qualificado que buscava todo o tempo responder a questão que veio a se colocar para o governo municipal com essa mudança: como urbanizar? Por outro, reflete, também, a influência das transformações na agenda urbana interacional na gestão da cidade do Rio de Janeiro, bem como na de outros municípios do país. A investigação desses aspectos levantou uma dúvida sobre o caráter realmente transformador das políticas de urbanização inicialmente levadas a cabo por um prefeito, Israel Klabin, que era um homem de negócios de sucesso e íntimos de atores econômicos e políticos, nacionais e internacionais. Com entrevistas, pesquisa documental e em jornais da época, propõe-se entender as politicas de urbanização sob a ótica da governamentalização desses territórios, ou, em outras palavras, como uma tecnologia de gestão da população e dos espaços favelados. / This thesis analyses the conditions that made possible and acceptable the perception that different favelas, but contiguous in each other, were perceived as a territorial unit named Complexo do Alemão. This perspective brings to the late 1970s and early 1980s, period recognized by the urban carioca literature as the period in which the solution to the favela problem, by the public authorities, becomes a set of many interventions, which was conventionally named as urbanization, in detriment of the removal policy. This reorientation of the public authorities, by one side, triggers an abundant production of information about this territories, through the assembly of a qualified technical condition, that seeked at all times to answer the question that was put to the municipal government with this change: how to urbanize? On other hand, reflects, between other motivations, the influence of the transformation in the international urban agenda in the urban management of the city of Rio de Janeiro, but also in other cities of the country. The investigation of these aspects raised a doubt on the real transformer character of the urbanization policies initially carried out by a mayor, Israel Klabin, that was a successful businessman and close to economic and political actors, national and international. With interviews, documental research and in newspapers of the period, it proposes to understand the urbanization policies by the perspective of the governmentalization of these territories, or, in other words, as a management technology of the population and slum areas of favela.

Execução de obras de urbanização de favelas: Favela Jardim Santo André - Santo André, Região Metropolitana de São Paulo. / Execution of slums upgrading construction works: Jardim Santo André Slum - Santo André, Metropolitan Region of São Paulo.

Ferreira, Júlia Maria Strazdas Martins 29 June 2006 (has links)
A urbanização de favelas consiste em uma intervenção – prioritariamente governamental – que busca adequar sítios irregulares através de melhoria das condições de moradia e de saúde de seus moradores. Verifica-se, decorrente de diversos motivos, alterações entre o que é projetado e o que é executado, suscitando um questionamento sobre qual o nível de detalhamento dos projetos é suficiente para subsidiar as obras. Por meio de um estudo de caso, esta pesquisa investiga quais são as dificuldades na implementação de projetos em campo; as reais possibilidades do projeto; os motivos que promovem alterações nos projetos no momento da obra; e as possibilidades de contorná-los. Da descrição do caso observou-se a necessidade de adequação dos produtos e de melhoria na socialização das informações. Da análise do cadastro da obra foram verificadas as execuções que contrariaram as orientações dos projetos, tanto decorrentes da necessidade de ajustes locais, quanto de desobediência ou incompreensão das soluções. Das entrevistas constatou-se que, em função de cada intervenção, há necessidade de graus de detalhamento diferenciados para cada item de projeto e para cada etapa de elaboração. Conclui-se pela necessidade de aprimoramento do processo de implementação do empreendimento para obtenção de resultados mais eficazes. / Slums upgrading consists in an intervention – mainly governmental – that aims to adequate irregular sites by improving the dwelling and health conditions of their inhabitants. Due to several reasons, there are changes comparing what is designed and what is executed, which raises questions about how detailed the designs should be to subsidize the construction works. By means of a case study, the present research investigates the difficulties faced in the implementation of designs on the field; the real possibilities of the design; the reasons that promote changes in the designs when the construction work is started; and the possibilities to skirt them. The case description showed the need to adequate the products and to improve the socialization of information. The analysis of the construction work as built revealed the executions that contradicted the designs’ orientations, deriving both from the need of local adjustments and from disobedience or misunderstanding of the solutions. The interviews showed that, to each intervention, different degrees of detail are necessary for each item of the design and for each elaboration stage. In conclusion, it was found that the implementation process of the project must be perfected so that more efficient results are obtained.

Aumento da capacidade da estação de tratamento de água nº 2 de Valinhos - SP, utilizando polímero natural como auxiliar de floculação / Upgrading capacity of water treatment plant nº 2 of Valinhos-SP, by natural polymer addition as flocculation aid

Souza, Luiz Carlos Alves de 14 March 2003 (has links)
A utilização de polímero natural como auxiliar de floculação pode ser alternativa interessante para o aumento da capacidade de estações de tratamento de água para abastecimento. O polímero natural é um produto de baixo custo, de fácil preparo e aplicação. Por ser produzido em larga escala e utilizado nos mais diversos setores da indústria, o polímero natural apresenta-se como alternativa aos polímeros sintéticos que, de maneira geral, são produtos de elevado custo e produzidos com matéria prima geralmente importada. No presente trabalho procurou-se demonstrar a eficiência dos polímeros naturais de fécula de batata e de fécula de mandioca na clarificação da água, mediante a realização de ensaios de laboratório e testes de campo - realizados na estação de tratamento ETA-2 de Valinhos (SP) - para diferentes características da água bruta. A gelatinização dos polímeros foi feita à temperatura ambiente, utilizando-se hidróxido de sódio. Para os testes na ETA-2, foram aproveitadas as instalações existentes e executadas pequenas adaptações para aplicação dos polímeros naturais. Conclui-se que, apesar de alguns ajustes que devem ser feitos, principalmente nos filtros, é possível utilizar os polímeros naturais na ETA-2 com grande probabilidade de êxito, com vistas ao aumento da capacidade de tratamento. Os resultados demonstraram que, tanto o polímero de fécula de batata como o de fécula de mandioca, foram eficientes como auxiliares de floculação na clarificação da água. / Natural polymer utilization as flocculation aid may be an effective alternative for upgrading the capacity of water treatment plants with low cost, easiers to prepare and apply. As natural polymers are large scale produced and applied in many different industrial sectors, it comes as a fesiable alternative for synthetic polymers that are generally high cost and made of imported materials. On this work it was tried to show the efficiency of natural polymers such as potato and manioc starch, for clarifying water by jar-test evaluations and field tests - carried out on water treatment plant WTP-2 of Valinhos (SP - Brazil) - for different characteristics of raw water. The polymer gelatinization was obtained by sodium hydroxide application. For the tests at WTP-2 the existing facilities were utilized and only small adaptations were made to apply natural polymers. The conclusion was, in despite of needing filters adjustments which must be made on water treatment plant for polymer application, it is possible to utilize the product with high successful probability for upgrading the capacity of water treatment plant. The results showed that even potato as well as cassava starchs were efficient on plant clarified water.
