Abstract (sommario):

The following thesis makes a critical attempt for approaching the concept of artistic value based on case-study of a unique in its kind contemporary artwork. A cultural production that peculiarly illustrates a paradoxical process of preconsecration as high art, within the both the aesthetic and art professional fields it is hosted within. The Cremaster Cycle of Matthew Barney, a notorious and at the same time, enigmatic production of contemporary art, illustrates a process of contemporaneous art historical indexing and to the creation of cultural capital. Such processes, facilitated by private and institutional patronage, are understood as integral to the art production from the 1990s and onwards, making the professional field of art equally important as the aesthetic one. Within this particular frame, we will see the faithful coming together of various agents, in support of an aesthetic idea or else, a cultural product, whose form seems intrinsically bound to both a social and an economical agenda, while at he same time it expresses a very particular aesthetic one. Due to such characteristics the research and analysis of the case study was carried out against the background of Pierre Bourdieu’s ‘field theory’, echoing therefore the aesthetic ‘field of the Cremaster Cycle’ . Using as disciplinary pillars from one side, the abstract and idiosyncratic realm of art theory and on the other the practical world and language of commerce, the thesis will attempt to look into the specific conditions that contributed to the Cremaster Cycle’s immediate valorization as high art. In this route the question of artistic value is one of great importance and yet, it is not one that could be sufficiently answered. Though, what becomes definite through this research project, brought forward in such times when the notions of both, artistic production and value are so expanded and malleable, is an intense urgency for new definitions. Somehow, it seems that the core problematic of this necessity for reconfiguration evolves around the notion of autonomy. This time not of the artwork but of the ones that attribute its value, namely the field; And this is exactly what the Cremaster Cycle offers us in perspective. Is there the possibility of objective or autonomous artistic value within a knowingly non-autonomous art?

Abstract (sommario):

In the past decades, while many countries planned and undertook more and bigger infrastructure megaprojects, poor performance has marred their delivery, for example through cost overruns, delays, disputes, and shortfalls in expected benefits. It is therefore important to improve performance levels, especially in infrastructure megaprojects that can considerablely influence the economy, society and environment. Project evaluation is an effective tool in project performance management as it provides stakeholders with a management process through which they can learn from the past and perform better in the future. Most of the traditional evaluation approaches emphasize the three basic success criteria of time, budget and quality. However, with the increasing importance of sustainability criteria and concerns, as well as the growing imperatives for stakeholder engagement, it has already been suggested to reconsider and redefine value by also evaluating other factors, such as those related to the environment and society. Therefore, an integrated whole life cycle value (WLCV) evaluation framework is proposed in order to improve infrastructure megaproject WLCV performance. In this study, whole life cycle (WLC) evaluation has a two-fold meaning: (i) the evaluation is based on a set of value factors drawn from a WLCV system; and (ii) this evaluation is a systematic continuous process from the start to the end of the project. However, considering the unique characteristics of every project, a totally fixed or static structure and content framework is neither sufficient nor suitable for the various types of infrastructure megaprojects. The recommended solution is to develop a semi-flexible framework that enables a pre-determined step by step dynamic structure formulation and a flexible WLCV system. In order to measure project WLCV derived from stakeholders’ expectations, from more objective and persuasive perspectives, the relevant value objectives/criteria/indicators, their weightings and targets will be identified, integrated and developed through this WLCV system. Cross-criteria relationships which have not been addressed adequately before, will be dealt with by assigning appropriate weightings. It is also proposed to build a database to store completed project information including various stakeholders’ expectations expressed in the form of value objectives. In order to develop the above proposed framework, a basic literature review was conducted to reveal and analyze the significant evaluation problems, identify trends in stakeholder engagement and develop the concept as well as typical criteria and indicators of project WLCV. Meanwhile evaluation practices, stakeholder engagement in the process of evaluation and WLCV perspectives in the Hong Kong construction industry were examined through a first round of interviews and the first of two focus group meetings. The first focus group meeting, second round interviews and the second focus group meeting were conducted to improve the proposed framework by investigating the importance of assigning an appropriate weighting to each value objective and each group of stakeholders; elaborating the various value criteria to measure value objectives at appropriate points of a project WLC. The findings from literature reviews, interviews, focus group meetings and a case study were integrated and injected into developing the aforementioned framework for building and administering the evaluation of project WLCV in ways that could improve desired project WLC performance. The outputs of the current research are expected to assist clients of infrastructure megaprojects to build a sense of ownership among all the key stakeholders at the outset, and to help motivate all stakeholders to be more co-operative, with a view to jointly targeting and monitoring an agreed project WLCV, thereby helping to achieve better WLC performance on infrastructure megaprojects. The main contributions to knowledge from this research are in developing a comprehensive evaluation methodology which combines and refines relevant components from existing evaluation approaches as well as injects the WLCV concept and criteria into a more holistic approach that is expected to identify and address current inadequacies in infrastructure megaproject delivery.

Abstract (sommario):

This thesis examines the concepts of value creation, capture and exchange in limiting the liability of newness for nonprofit museums entering the sector. There has been considerable examination of cultural value in relation to museums. However, little is known about how value is created, captured and exchanged for stakeholders in new museums. It is posited that value creation, capture and exchange constitute a value cycle. Through this value cycle management in new museums detects and limits the liability of newness. The ability to detect and limit the liability of newness enables the continuation of the museum. If the liability of newness is not limited, it may mean that a new museum exits the sector or is transformed. The concept of a value cycle is derived from an examination of the nonprofit management literature, aspects of the for-profit management literature and the arts and museum management literature. Value creation is a key concept in the three literature areas. Value creation in this context, is specifically defined as the worth of the physical manifestation of the museum. It resides in the building and the collection, services and programs within the building. It is suggested that this value needs to be transformed and consumed by a range of stakeholders. The transformation of value creation is denoted as value capture. Value capture is the appeal of programs, projects and activities. Value capture includes how well the products and services align with particular stakeholders, how accountable the managers are to stakeholders and how products and services are consumed by stakeholders. The measure of how managers have been able to capture value is in the realm of value exchange. Value exchange is the merit of programs, projects and activities. Value exchange is in the form of revenue raised through sponsorship; continuation of revenue investment by the principal stakeholder, the state; time and money transacted by visitors; and intangible exchange such as leadership and reputation enhancement through collaborations. A Value Cycle Framework of New Entrant Museums is then developed as a working analytical tool to assess how the value cycle operates and how the liability of newness is detected and limited by museum management. x The Value Cycle Framework is used to assess four cases. These case studies include the National Museum of Australia as a purpose built new entrant; the Australian National Maritime Museum as a purpose built new entrant; the Mint as a recycled new entrant; and the Earth Exchange as a refurbished new entrant. Each case is assessed discretely using secondary and primary source material and analysing qualitative data generated from interviews with key stakeholders. The cases are then compared in order to track similarities and differences in relation to value creation, capture and exchange. The research findings suggest that a value cycle is operating in relation to new entrant museums. This value cycle is dynamic and non-sequential. Until value creation is floated for a range of stakeholders it is difficult for managers to know the worth of their content, location or their building. Value creation is a nominal starting point, signifying the arrival of a new entrant in the museum marketplace. However, value capture is the zone that is the most vulnerable and volatile for managers of new museums. Typically in these case studies value capture includes a disruptive episode, such as a review process that indicates the liability of newness. Managers within the museum who can respond and resolve contradictions between museological beliefs and the demands of stakeholders (and in so doing limit the liability of newness) are likely to continue museum operations. Senior executives who find such reconciliation more difficult, jeopardize the future operations of the museum to such an extent that the museums close or are transformed within the museum sector. Through these four case studies a revised Value Cycle Framework is developed as an analytical device. This analytical framework can assist in understanding the processes involved in new entry for museums.

Thesis (MBA)--University of Stellenbosch, 2010.
AFRIKAANSE OPSOMMING: Waarde- en groei-beleggingstrategieë dateer terug na Fama en French (1992) en Lakonishok, Shleifer en Vishny (1994). Bogenoemde studies is gebaseer op vroeë navorsing wat die fokus verskuif het om sodoende waardasieverhoudinge en maatskappygrootte te gebruik as toonaangewende verklarende maatstawwe vir aandele-opbrengste. Toenemende studies in hierdie beleggingsveld het die akademiese en beleggingsgemeenskap oortuig dat ’n waardegebaseerde beleggingstrategie, gemiddeld, ’n groeigebaseerde beleggingstrategie oortref. Waarde- en groei-eienskappe word algemeen aanvaar en deur fondsbestuurders en beleggers as onderskeidende beleggingstrategieë aangewend. Hierdie eiesoortige beleggingstrategieë is op die Suid-Afrikaanse mark vir die periode 1990 tot 2009 toegepas. Die beduidende veranderinge binne die ekonomiese klimaat en aandelemarkte was die oorhoofse rede vir die insluiting van die ekonomiese siklusse in die navorsing, spesifiek die opswaai- en afswaai-fases van die ekonomie. Die Sharpe-, Treynor- en Inligting–prestasiemaatstawwe vir waarde- en groei-portefeuljes is in hierdie studie vergelyk en geanaliseer. Normaalweg word prestasie-beoordeling nie begin met ’n gedetailleerde analise van die opbrengsverdelings om te bepaal watter prestasie-maatstaf meer voortreflik is nie. Die opbrengsdensiteit vir alle portefeuljes is bepaal om sodoende die opbrengsverspreidings en risikooorwegings beter te verstaan binne die onderskeie ekonomiese siklusse. Die bevindinge binne die Suid-Afrikaanse konteks was wel ooreenstemmend met voorafgaande navorsing dat waardegebaseerde investering groeigebaseerde investering oortref vir aandele met hoër waardasieverhoudinge teenoor aandele met laer waardasieverhoudinge. Die gemiddelde maandelikse prestasie van waarde-portefeuljes het ook groei-portefeuljes oortref in die ekonomiese opswaai-siklusse, wat ooreenstemmend is met soortgelyke navorsing wat in ander markte gedoen is. In die ekonomiese afswaai-siklus het groei-portefeuljes waarde-portefeuljes oortref, ooreenstemmend met die van die Amerikaanse mark. Die navorsing dui daarop dat waardegebaseerde investering voortreflik is oor die volle steekproefperiode, wat beteken dat beleggers wat waarde-beleggingstrategieë volg hoër opbrengste kan verwag in alle ekonomiese siklusse, maar die voordele sal groter wees in tye van ’n ekonomiese opswaai. Die wisselvalligheid van opbrengste binne die twee ekonomiese siklusse is sigbaar en beklemtoon die noodsaaklikheid om die ekonomiese siklus in beleggingstrategieë en -besluite in te sluit. Die ekonomiese siklus verbreed die dimensie tot die evaluasie van waardegebaseerde beleggingstrategie en dit is noodsaaklik dat dit ’n geïntegreerde deel vorm van die evaluasieproses.
ENGLISH ABSTRACT: Value and growth investment strategies can be traced back to Fama and French (1992) and Lakonishok, Shleifer and Vishny (1994). The studies built on earlier work done and lead to attention being shifted to valuation ratios and company size as leading explanatory indicators for stock returns. Based on the accumulated evidence from studies, the academic and investment community came to agree that value investment strategies, on average, outperform growth investment strategies. Value and growth, are widely recognised and used by money managers and investors as distinctive investment strategies. These style-specific investment strategies were tested on the South African market for the period 1990 to 2009. The significant changes within the economic conditions and securities markets motivated the research to include the business cycle – specifically, contraction and expansion of the economy – within the scope of this study. The Sharpe, Treynor and Information performance ratios, that were calculated for compiled value and growth portfolios, were compared and analysed. The performance evaluation is not normally initiated with a detailed analysis of the return distribution in order to determine which performance measure is superior. The return densities for all portfolios were calculated in order to gain a better understanding of return distributions and risk considerations within the different business cycles. The results indicated that, within the South African context, value investing did outperform growth investing as indicated by previous research that stocks with high valuation ratios tend to outperform stocks with low valuation ratios. The mean monthly performance of value portfolios also outperformed growth portfolios in the period of economic upswing, which is a similar result as that of other markets where this kind of research has been conducted. In the economic downturn period growth investing seems to be superior to value investing similar to that of the US market. The study indicates that the superior performance of value investing is robust for the whole sample period, meaning that investors will be better off investing in stocks with high valuation ratios for all economic conditions, but the benefits of value investing would be greater during periods of economic upswing. The volatility of returns within the two economic conditions is quite evident and highlights the importance of incorporating business cycles into investment strategies and decisions. The business cycle adds another dimension to value investing strategy evaluation and should be incorporated in the evaluation process.

Abstract (sommario):

The demand for energy is increasing throughout the world, and fossil fuel resources are diminishing. At the same time, the use of fossil fuels is slowly being reduced because it pollutes the environment. Research into alternative energy sources becomes necessary and important. An alternative fuel should not only replace fossil fuels but also address the environmental challenges posed by the use of fossil fuels. Hydrogen is an environmentally friendly substance considering that its product of combustion is water. Hydrogen is perceived to be a major contender to replace fossil fuels. Although hydrogen is not an energy source, it is an energy storage medium and a carrier which can be converted into electrical energy by an electrochemical process such as in fuel cell technology. Current hydrogen production methods, such as steam reforming, derive hydrogen from fossil fuels. As such, these methods still have a negative impact on the environment. Hydrogen can also be produced using thermochemical cycles which avoid the use of fossil fuels. The production of hydrogen through thermochemical cycles is expected to compete with the existing hydrogen production technologies. The sulphur iodine (SI) thermochemical cycle has been identified as a high-efficiency approach to produce hydrogen using either nuclear or solar power. A sound foundation is required to enable future construction and operation of thermochemical cycles. The foundation should consist of laboratory to pilot scale evaluation of the process. The activities involved are experimental verification of reactions, process modelling, conceptual design and pilot plant runs. Based on experimental and pilot plant data presented from previous research, this study presents the simulation of the sulphur iodine thermochemical cycle as applied to the South African context. A conceptual design is presented for the sulphur iodine thermochemical cycle with the aid of a process simulator. The low heating value (LHV) energy efficiency is 18% and an energy efficiency of 24% was achieved. The estimated hydrogen production cost was evaluated at $18/kg.

Abstract (sommario):

The primary objective of any corporation should be shareholder wealth maximisation. A firm's working capital policies have an effect on the firm's expected future returns and the risk associated with the returns, which ultimately have an impact on shareholder wealth. Efficient working capital management is a fundamental portion of the overall corporate strategy to create shareholder value. In this study the relationship of corporate profitability and working capital management was investigated. This relationship is examined using regression analysis. A sample of 118 firms listed on the Johannesburg Securities Exchange (JSE) for the period 2003 to 2007 was used. The purpose of this study is to establish whether a relationship exists between working capital management efficiency and profitability, considering the cash conversion cycle and operating profitability of the firm. The results of the regression analysis indicated that a statistical significance exists for three of the five years (2003 - 2005) analysed between profitability, measured with the gross operating profit, and the cash conversion cycle. It is observed (2003-2005 regression results) that a lower gross operating profit is associated with an increase in number of days accounts payable. The negative relationship between accounts receivable and firms' profitability (for 2003-2005) suggests that less profitable firms will pursue a decrease of accounts receivables in the attempt to reduce cash gap in the respective cash conversion cycles. The negative relationship between the number of days inventory and corporate profitability (for 2003-2005) suggests that a sudden decrease in sales accompanied by mismanagement of inventory, will lead to tying up excess capital at the expense of profitable operations. Managers or owners of firms can improve profits for firms by handling correctly the cash conversion cycle and keeping each individual component (accounts receivable, accounts payable and inventory) to an optimum level. These results (for 2003-2005) suggest that managers can create value for shareholders by reducing the cash conversion cycle and its individual components.

Abstract (sommario):

Résumé Une demande croissante sans cesse de produits alimentaires à base d’animaux influence la productivité des systèmes mondiaux de production alimentaire, et des mesures indispensables pour freiner la dégradation de l’environnement promettent des effets similaires. Si les scénarios de demande future peuvent être satisfaits de manière durable, cela dépend notamment de la possibilité de réduire de manière significative l'impact de l'aquaculture et de l'élevage sur l'environnement. Des recherches récentes suggèrent que l'utilisation d'aliments à base d'insectes (IBF) pourrait apporter une contribution significative à cet égard, et des arguments valables sont avancés pour soutenir cette hypothèse. Les larves de mouches, comme celles des mouches domestiques (Musca domestica) ou des mouches soldat noir (Hermetia illucens), sont en mesure de puiser des nutriments dans un large éventail de ressources organiques, y compris celles impropres à la consommation humaine. Cela crée la possibilité de convertir (et de réduire considérablement) les déchets organiques de faible valeur, tels que le fumier ou le sang animal, en protéines de haute qualité et en énergie alimentaire, qui se sont avérés appropriés pour nourrir différents poissons d'aquaculture et du bétail monogastrique.Bien que le concept IBF promet d’importants avantages et ait démontré sa faisabilité technique, il n’existe encore aucun système établi permettant de tester les avantages supposés en termes de durabilité. Dans cette thèse, nous avons essayé de surmonter cette lacune par la modélisation de tels systèmes. Notre objectif central était d'identifier les aspects influençant le potentiel d'application des IBF dans différents contextes géographiques et de définir des voies d'optimisation pour une mise en œuvre durable. En nous basant sur des données expérimentales recueillies lors d'essais d'élevage menés en Europe (Espagne et Slovaquie) et en Afrique de l'Ouest (Ghana et Mali), nous avons formulé la conception d'un ensemble de versions de systèmes améliorés élevant M. domestica et H. illucens sur différents substrats organiques de faible valeur. Les modèles de production génériques ont servi comme base d’une analyse du cycle de vie ex ante, dans laquelle nous avons exploré les performances des systèmes à l’aide d’analyse du cycle de vie environnementale (ACV) et de l’analyse des coûts du cycle de vie (ACCV).Les ACVs et ACCVs ont montré que les performances environnementales et économiques des IBF sont largement fonction de l’efficacité de conversion des systèmes, de l’organisation du processus de production (c’est-à-dire de l’apport de main-d’œuvre et d’équipements technologiques) et du contexte géographique. La combinaison de ces facteurs a fourni des avantages pour les configurations simplistes utilisées dans la production de M. domestica en Afrique occidentale tropicale dans des conditions de ponte naturelle (c'est-à-dire d'inoculation de substrat par le biais de mouches présentes à l'état naturel). L'inoculation artificielle (c'est-à-dire l'inoculation du substrat par le biais de larves nourries provenant d'une colonie d'adultes en captivité), utilisée dans la production de H. illucens en Afrique de l'Ouest et de M. domestica dans le sud de l'Espagne, a favorisé une efficacité de conversion élevée, mais a augmenté les impacts environnementaux et les coûts, parce que le système complexe et l'organisation de processus à forte intensité de main-d'œuvre ont considérablement accru les intrants de main-d'œuvre et d'infrastructures de production.Une comparaison avec des aliments conventionnels riches en protéines a mis en évidence des inconvénients environnementaux et économiques pour les modèles de production actuels des IBF, notamment en ce qui concerne les aliments végétaux (par exemple, le tourteau de soja). Les disparités entre les alimentations IBF et conventionnelles reflètent l’utilisation des capacités sub-optimaux des systèmes (effet d’économie d’échelle insuffisant), ainsi que la perte d’énergie et de biomasse le long de la chaîne trophique (producteurs autotrophes vs consommateurs hétérotrophes). Les résultats soulèvent des doutes légitimes sur les avantages en termes de durabilité d’une mise en œuvre d'insectes dans les chaînes de valeur agricoles actuelles. Le succès commercial dépend en grande partie du niveau de salaire spécifique au contexte, des prix des substrats d'élevage et de la manière dont les marchés évaluent les multiples fonctions que les insectes sont capables de fournir. S'agissant de la performance environnementale, nos résultats nous amènent à conclure que la production d'IBF ne présente aucun avantage par rapport aux aliments conventionnels.L’évaluation de systèmes de production encore hypothétiques impliquait une bonne quantité d’hypothèses et d’approximations. Étant donné ces multiples sources d'incertitude et compte tenu du fait que seul un nombre limité de conceptions de systèmes possibles sont prises en compte, les déclarations sur le potentiel d'application d'IBF n'ont aucune validité universelle et doivent être interprétées avec prudence. Cependant, nos résultats contribuent à une meilleure compréhension des facteurs influant sur le potentiel d’application des systèmes de production d’insectes et constituent un point de référence précieux pour les discussions scientifiques et les activités de recherche et développement futures visant à mettre en place des modes de production alimentaire durables.Bien que nos recherches n’apportent aucun soutien aux avantages environnementaux ou économiques supposés de l’utilisation d’insectes dans l’alimentation animale, il est possible que leur utilisation comme aliment destiné à la consommation humaine directe (c’est-à-dire comme substitut possible aux produits à base de poisson et de viande) constitue une solution durable aux problèmes actuels et futurs. Nous recommandons donc aux recherches futures de se concentrer sur les techniques permettant d'exploiter les insectes comme nourriture.

Abstract (sommario):

A new economic model for the evaluation of integrated Design, Production, and Logistic Support Systems (DPLSSs) is designed and developed in this thesis. The DPLSS model was created after a survey of Life Cycle Costing (LCC) applications revealed that no models for assessing integrated design, production, and logistic support systems were available. The evaluation technique the model is based on is called Life Cycle Value Assessment (LCVA). LCVA differs from LCC in that it emphasizes consideration of life cycle revenues as well as costs.

The system addressed by the DPLSS model has a life cycle which includes product design, production capability design and construction, production, product distribution, logistic system support and maintenance, and system disposal. The baseline production capability assumed when developing the DPLSS model involves batch processing, forming the base material into individual units, and performing detailed processing operations. It has also been assumed that items produced are non-repairable.

The DPLSS model facilitates the evaluation of new DPLSSs by leading managers through the new LCVA methodology, A Cost Breakdown Structure (CBS) which is compatible with the DPLSS life cycle has been developed as a basis for the model. This CBS is used to address DPLSSs descriptively and nonnatively during LCVA evaluations.

A menu-driven computer program has also been developed to implement the DPLSS model on an IBM PC. This program leads users through the new LCVA-based methodology, performs economic and sensitivity analyses on their inputs, and then allows "what-if?â analyses on varying system configurations to be performed.

Abstract (sommario):

Life Cycle Cost Analysis (LCCA) forms an important part of asset management practices and provides an informed decision support. The holistic nature of LCCA includes life cycle assessment (LCA) as an important component alongside economic life cycle cost analysis. The drinking water industry is right now lacking a reliable cost data structure which will ensure that all the utilities capture the same set of cost data. Also, models and tools currently available in the academia and industry are purely deterministic in nature and do not cater to uncertainty in the data. This study provides a framework for a holistic life cycle cost analysis tool which will help drinking water utilities to prioritize the activities and optimize the cost spending of the utility. The methodology includes the development of a cost data structure, a life cycle cost analysis and a life cycle assessment model in the form of an excel spreadsheet. The LCCA model has the capability to compare different pipe materials, installation, condition assessment, rehabilitation and replacement technologies. Whereas, LCA model can compare different pipe materials based on greenhouse gas emissions calculations. The final step of the methodology includes piloting the model with data from utility A. The analysis has been shown in the form of three case studies - comparison of two pipe materials, two pipe installation technologies and two pipe rehabilitation technologies. The case studies provide results in the form of comparison of total life cycle costs for different alternatives and hence a better alternative can be chosen.

Abstract (sommario):

The literature on nexus between trade and business cycle synchronization have provided mixed and weak evidence of the effect of trade on business cycle synchronization as a result of lack of value-added bilateral trade data which provides solution for overestimation or underestimation of shock exposure when using gross trade data. Also, due to limited data on sectoral bilateral value-added trade, the literature has not been able to pinpoint the sectors where synchronization is necessary in order to economically direct all effort to these sectors in forging economic integration. The paper uses value-added trade data to examine the impact of trade on business cycle synchronization at the aggregate level and sector level and find a highly significant and highly positive effect of trade on the aggregate level. Estimates for agriculture, manufacturing, construction, total business, electricity gas and sewer, and other service sectors yield a positive significant effect in the service sector, indicating that attention should be focus on the service and business sector when integrating economically.In this paper we examine output cycle synchronization patterns of the countries that joined the Eurozone later and countries that are in preparation or committed to join in relation to the original Eurozone members. We analysis this in the contest of before, during and recovery periods of the global financial crisis investigate the differences in the patterns of synchronization for late and future members of the Eurozone. For more understanding, we examine the pattern on disaggregate level using data for agricultural, manufacturing, construction, utility, total business and other services sectors from 1995-2015. Also, we examine the importance of trade on output synchronization both on the aggregate and disaggregate level using System GMM which not only solves the problem of endogeneity, but it estimates the persistence of business cycle synchronization efficiently. The result provides evidence of a positive persistence; however, synchronization pattern differs between late and future member states. Also, the financial crisis had a negative effect on synchronization in the European sub region as result the difference in the response by member states. The result shows a weak evidence of the importance of trade as a channel of synchronization. Even though previous studies have provided evidence improvement in UK and the Eurozone output comovement, Brexit came to pass. This has questioned the potency of the Enlargement of the Eurozone Initiative. This paper reexamines the degree of business cycle synchronization between the Euro area countries and United Kingdom in attempt to find an economic reason for Brexit. We also examine if the disaggregate economy have share similar pattern as the aggregated economy using the output synchronization in the agricultural, manufacturing, constructions, utility, total business and other service sectors between the euro area countries and United Kingdom. Using valued-added trade data between 1995 and 2015 from WTO-TiVA database we further examine effect of trade (sectoral trade) on the output (sectoral output) synchronization. Furthermore, we analyze the same questions in the contest of before and after the global financial crisis. The result show that the UK-EMU trade channel is no important to the output cycles synchronization. Also, due the unstable pattern or persistence of UK-EMU synchronization the EMU will have little effect from the Brexit if there exit one.

Abstract (sommario):

The purpose of this thesis will be to explore conceptions of waste in Nepal’s rural village of Simigaau to understand what constitutes waste and in what ways it is critical to the community’s physical and cultural survival. Due to the contribution of many aspects of daily life in the creation of “waste” in Simigaau –what it is and what it means – I hope to use a whole systems approach to understand the multitude of factors that affect how villagers view waste and whether its value can provide insight into a local way of life. Moreover, I aim to explore whether a community’s waste – seen and unseen – provide insight into a local way of life and if so, how this insight may be applied to both Nepal at large and connotations of “waste” in the West.

Increasing crop productivity is a challenge as old as human history. Advancements in technology have allowed farmers to produce ever-increasing amounts of food on a given amount of land. With the world's population expected to reach roughly nine billion by 2050 (United Nations 2013), the demand for food will require increasingly improved methods of agricultural production. One of these potential methods is the use of unmanned aerial vehicles (UAVs) to monitor crop health and identify potential issues. This thesis will explore how current stakeholders plan to utilize this technology and the perceived value they believe it will deliver across the various phases of the crop cycle. This thesis begins by reviewing modem precision agriculture management practices and discussing how remote sensing plays a role in improving the efficiency of these types of farming methods. It also identifies a number of challenges facing the industry to include the impact of current regulations on the market. This thesis develops a stakeholder value network that clarifies the tangible and intangible value exchanges between the focal organization and its stakeholders. As well as constructing an OPM (Object Process Methodology) model to describe the system and demonstrate the stakeholder interactions and system process and sub-process decomposition. It also provides visual display of how the value is delivered across these processes. The final aspect of the research for this thesis is to identifies the lead users for these systems and determines how they measure the value of the data provided by UAVs for remote sensing and crop management decisions in support of farming operations. The value proposition for the various crop phases and the ideal uses cases discussed by lead users in this thesis may be used to guide future research in agriculture technology development, and drive further innovation in the emerging field of commercial unmanned aerial system use.

Abstract (sommario):

The objective of this work is to provide various improvements to the modeling and uncertainty quantification of fatigue lives of materials as understood via simulation of crystal plasticity models applied to synthetically reconstructed microstructures. A computational framework has been developed to automate standardized analysis of crystal plasticity models in the high cycle fatigue regime. This framework incorporates synthetic microstructure generation, simulation preparation, execution and post-processing to analysis statistical distributions related to fatigue properties. Additionally, an improved crack nucleation and propagation approach has been applied to Al 7075-T6 to improve predictive capabilities of the crystal plasticity model for fatigue in various loading regimes. Finally, sensitivities of fatigue response to simulation and synthetic microstructure properties have been explored to provide future guidance for the study of fatigue quantification based on crystal plasticity models.

Abstract (sommario):

This master thesis seeks to investigate how an Argentinean institute support its members to learn Global Value Chains and Life Cycle Assessment. Two important methodologies that can be used as a basis to form sustainable strategies based on analyses of products or services. A Global Value Chains and Life Cycle Assessment course is held to the institute’s members who wishes to learn them. This case study has analysed the course design, the outcome and the institute’s organizational structure for professional development based on a 15-factor framework and relevant learning theories. Course evaluations, data analysis, group interviews and questionnaires were the research methods used to gather data for this case study. The thesis reveals that several important factors for professional development that facilitate the learning of GVC and LCA can be found at the institute. But, the current course design and the institute’s restriction of access to data prevents good learning outcomes for the course participants. Several suggestions regarding the course design and organisational structure were presented, based on the findings of this study.
Detta examensarbete syftar till att undersöka hur ett argentinskt institut stöder sina medlemmar att lära sig om globala värdekedjor (GVC) och livscykelanalys (LCA). Två viktiga metoder som kan användas som utgångspunkt för att bilda hållbara strategier baserade på analyser av produkter eller tjänster. En GVC och LCA kurs hålls för institutets medlemmar som vill lära sig metoderna. Denna fallstudie har analyserat kursdesignen, utfallet och institutets organisationsstruktur för kompetensutveckling baserad på en 15-faktors ramverk och relevanta lärteorier. Kursutvärderingar, dataanalyser, gruppintervjuer och frågeformulär var de undersökningsmetoder som användes för att samla data för denna fallstudie. Studien visar att flera viktiga faktorer för kompetensutveckling underlättar lärandet av GVC och LCA på institutet. Det framgår däremot att den nuvarande kursdesignen och institutetss begränsning av tillgång till data förhindrar goda läranderesultat för kursdeltagarna. Flera förslag om kursdesign och organisationsstruktur presenteras, baserat på resultaten från denna studie.

Abstract (sommario):

Esta pesquisa, com caráter conclusivo descritivo, buscou verificar se os valores pessoais mudam ao longo da vida, comparando-se dois diferentes momentos – em torno dos 25 anos e em torno dos 60 anos. Tendo como principal referencial teórico os trabalhos de Schwartz (1992; 2005b) e de Bardi et al. (2009), questionaram-se 106 pessoas que vivem, predominantemente, na região metropolitana de Porto Alegre, através de survey (PVQ-21) aplicada em entrevistas face a face, sobre os valores pessoais hoje e, com perguntas com abordagem histórico-longitudinal, resgataram-se os valores pessoais em torno dos 25 anos. O comparativo intragrupo foge das abordagens que contrastam valores pessoais entre gerações diferentes. Nesta amostra, observou-se a constância dos valores “Hedonismo” e “Conformidade” – diferentemente da teoria que previa que o primeiro teria menor importância com o avançar da vida e que o segundo tornar-se-ia mais importante; portanto, observa-se a busca pelo prazer como constante na vida das pessoas e que, ao longo da vida, as pessoas permanecem respeitando as diferenças de status e as expectativas sociais. Replicando-se achados de outros autores, verificou-se também a grande similaridade e mistura entre os valores “Realização” e “Poder”. Além disso, os valores de “Autotranscendência” e “Abertura à Mudança” estiveram muito próximos nos dois períodos contrastados – o que pode indicar que fazer o bem para os outros pode dar prazer e ser estimulante. Por fim, constatou-se que o nível de escolaridade é uma circunstância que impacta em muitas mudanças de valores e que a mudança do valor “Segurança” foi a mais correlacionada a eventos da vida.
This conclusive descriptive research aimed to verify whether the personal values change throughout life, comparing two different times - around 25 years and about 60 years. With the main theoretical work of Schwartz (1992, 2005b) and Bardi et al. (2009), 106 people that mostly live in Metropolitan Region of Porto Alegre were questioned, through survey (PVQ-21) applied in face to face interviews, about their personal values today and, with questions with longitudinal-historical approach, were rescued personal values when interviewed were around 25 years. The intra-group comparison differs from approaches that contrast personal values between different generations. In this sample, we observed the constancy of values "Hedonism" and "Conformity" – unlike the theory have predicted that the first would reduce importance with advancing life and the second would become more important; hence, the pursuit of pleasure was understood as a constant in people's lives and that throughout life, people remain respecting the differences of status and social expectations. Replicating the findings of other authors, it was also find the great similarity and mixing between the "Achievement" and "Power". Moreover, the values of "Self-Transcendence" and "Openness to Change" were very close in the two contrasted periods - which may indicate that doing good for others can be stimulating and pleasuring. Finally, it was found that the level of education is a condition that impacts many changes in values and change the value "Security" was the most correlated with life events.

The number of aircrafts at the end of life (EOL) is continuously increasing. Dealing with retired aircrafts considering the environmental, social and economic impacts is becoming an emerging problem in the aviation industry in near future. This thesis seeks to develop a holistic approach in order to analyze the value chain of EOL aircraft treatment in the context of sustainable development. The performed researches have led to eleven main contributions. In the first contribution, the complexity and diversity of the EOL aircraft recycling including the challenges and problem context are discussed. The second contribution addresses the challenges for estimation of retired aircrafts and proposes an integrated approach for prediction of EOL aircrafts. The third and fourth contributions aim to identify the players involved in EOL recycling context, values perceived by different shareholders and formulate that how such value can affect design decisions. Design stage consideration and manufacture’s issues are discussed and have led to four main contributions. The fifth contribution addresses the opportunities and challenges of applying green supply chain for aircraft manufacturers. In the sixth contribution, a decision tool is developed to aid manufactures in early stage of design for their green strategy choices. In the seventh contribution, a mathematical model is developed in order to analyze the strategic choice of manufacturers in response to EOL directives as the result of the interaction of competitors in the market. An internship project has been also performed in Bombardier and led to the eighth contribution, which addresses life cycle approach and incorporating the sustainability in early stage of design of aircraft. The ninth contribution introduces a methodology for analyzing the value chain in the context of sustainable development. Finally, the tenth and eleventh contributions propose a holistic approach to EOL aircraft treatment considering lean principals, sustainable development, and global business environment. An optimization model is developed to support decision making in both strategic and managerial level. The analytical approaches, decision tools and step by step guidelines proposed in this thesis will aid decision makers to identify appropriate strategies for the EOL aircraft treatment in the sustainable development context. Keywords: End of life aircraft, value chain analysis, sustainable development, stakeholders.

Abstract (sommario):

Nuclear energy is a source of carbon free power. With many countries striving to make deep carbon cuts in their energy sectors, nuclear energy could be a large part of the solution. One of the main obstacles standing in the way of the use of nuclear energy is the issue of used nuclear fuel disposal. According to the NEI, the U.S. creates about 2000 metric tons of used nuclear fuel per year and has generated around 76,000 metric tons of used nuclear fuel over the last 4 decades. While there are technical problems that need to be solved, it is primarily the public and political opposition to the disposal of used nuclear fuel that stands in the way of progress in this area. This work addresses this issue through Multi-Criteria Decision Analysis (MCDA). To make a decision among ten different fuel cycles, we have brought together five stakeholders: Nuclear Scientists and Engineers, Environmental Scientists, Economists, Political Scientists, and The General Public. Using Multi-Attribute Value Theory (MAVT), we have been able to develop decision models for each stakeholder as well as a model that combines them all and came to the conclusion that of the ten fuel cycles considered, the best decision is to continue to use On Site Dry Cask Storage. This decision is made with small sample sizes but the methodology could be applied at much larger scales and can potentially be used to choose a fuel cycle that encounters much less political and social opposition to its implementation.

Energy intake (EI) and energy expenditure (EE) across the menstrual cycle (MC), while considering body adiposity, have not been previously evaluated in the same individuals. This study mainly examined the variations in energy balance (EB) across MC. Seventeen women (Body fat-DXA:28.5%) participated in three identical sessions during distinct phases of the MC: Early-follicular, Late-follicular/ovulation and Mid-luteal (confirmed by basal temperature and sex-steroid hormones). EI, resting metabolic rate (RMR), physical-activity EE (PAEE), severity of PMS, leptin and relative-reinforcing value (RRV) of preferred foods were measured during each phase. No differences in body fat, EI, RMR, PAEE, leptin and RRV of food were noted across MC. Trends were noted in preferred snack (p=0.06) and combined snack/fruit (p=0.06) intakes, while differences were noted in severity of PMS (p<0.05) across phases. Changes in EB across the MC were not noted. PMS was more severe, and preferred snack and combined snack/fruit intakes were slightly higher during mid-luteal phase.

Abstract (sommario):

The intent of this thesis is to analyse the sustainability of producing bio-ethanol from cane molasses in Indonesia and its potential to replace gasoline in the transportation sector. A field trip was conducted in East Java, Indonesia, and data was gathered for analysis. Life cycle assessment (LCA) was performed to analyse the net emissions and energy consumption in the process chain. The greenhouse gas (GHG) emissions of the life cycle are 17.45 gCO2e per MJ of ethanol produced. In comparison to gasoline, this results in a 78% reduction in GHG emissions in the complete process chain. Net Energy Value (NEV) and Net Renewable Energy Value (NREV) were 6.65 MJ/l and 24 MJ/l. Energy yield ratio (ER) was 9.43 MJ of ethanol per MJ of fossil energy consumed in the process. Economic allocation was chosen for allocating resources between sugar and molasses. Sensitivity analysis of various parameters was performed. The emissions and energy values are highly sensitive to sugarcane yield, ethanol yield and the price of molasses. Alternative management options were considered for optimizing the life cycle. Utilizing ethanol from all the mills in Indonesia has a potential to replace 2.3% of all motor gasoline imports. This translates in import savings of 2.3 trillion IDR per year. Use of anaerobic digestion or oxidation ponds for waste water treatment is unviable due to high costs and issues with gas leakage. Utilizing 15% of cane trash in the mill can enable grid independency. Environmental impacts due to land use change (Direct & Indirect) can be crucial in overall GHG calculations. Governmental regulation is necessary to remove current economic hurdles to aid a smoother transition towards bioethanol production and utilization.

As the world grapples with the idea of impact to deliver essential services to the poor, measurement of real impact and the deriving Typical investments are measured purely investments are more complex as they al sustainability. investment as one of the important ways many queries are being raised about maximum value for the money invested. on the basis of financials but impact so look into social and environmental One of the methods is to conduct Life Cycle Assessments on the products being sold in the developing countries to give impact investors a better understanding of the environmental sustainability of the products, services and systems being invested in. However, to maximize the return on investment from a holistic impact perspective, sustainability needs to be evaluated across social, financial and environmental parameters. To have a substantial impact one needs to build the corresponding ecosystems for under-served societies: thus making the measurement of impact more accurate. The thesis focuses on the above by taking the example of Decentralized Renewable Energy enterprises in poor and underserved markets of the developing world. The project explores existing methodologies and criteria for impact investors to finance companies by balancing social, environmental and financial returns. By benchmarking and reviewing relevant approaches designed to spur sustainability and by identifying needs and gaps in the chosen methodologies the thesis proposes guidelines for impact investors to assess holistic sustainability. An analysis is provided by considering aspects across type of products sold/services provided by enterprises, type of target segments and motivations, type delivery models, type of capital and type of organizational structure and human resources. The guidelines are designed to help impact investors and enable social enterprises to look at sustainability metrics beyond Life Cycle Assessments. Finally, the importance of revising tax treatment of impact investments and the financial returns deserves serious consideration in order to effectively impact sustainable change.

Abstract (sommario):

The importance of sustainable development within the construction industry and its environmental and social impacts as well as economic significance has become more apparent over recent years. A key factor perceived as contributing to an organization’s business success is the integration of environmental, social, and economic issues into decision-making processes. The pressure from stakeholders regarding their expectations on sustainability has risen, and the importance of understanding the stakeholders’ opinions and perspectives in a construction project while simultaneously maintaining sustainable project management increases. The aim of this thesis is to analyze how stakeholder sustainability expectations can be promoted and achieved during a construction project life cycle and related building process stages by supporting the project manager using a specifically designed visual tool. This will be investigated by answering three research questions proposed in the Introduction chapter (page 5). The visual tool is created with the focus on defining and establishing sustainability parameters based on stakeholder expectations. The tool should be applicable to a broad variety of construction projects with different focus on stakeholder expectations. Furthermore, a theoretical framework has been developed as part of the analysis based on existing theories; the Business Model Canvas (Osterwalder & Pigneur, 2010), Global Performance Framework (International Civil Aviation Organization, 2009) and Stakeholder Theory. The proposed framework and its visual tool component are a means to support a project manager with stakeholder communication, collaboration and informed decision-making. The visual tool is adapted to include a common language and structure to enhance the communication and collaboration amongst key stakeholders and support a project manager with ensuring that the construction project is focused on achieving sustainability results expected by the stakeholders.
Betydelsen av hållbar utveckling inom byggbranschen och dess miljö- och sociala påverkan samt den ekonomiska betydelsen har blivit tydligare de senaste åren. En nyckelfaktor som uppfattas som bidragande till en organisations finansiella framgångar är integreringen av miljömässiga, sociala och ekonomiska frågor i beslutfattningsprocessen. Trycket från intressenter gällande deras förväntningar på hållbarhet har ökat, och betydelsen av att uppfatta intressenternas åsikter och perspektiv inom ett byggnadsprojekt – och samtidigt upprätthålla hållbar projektledning – har ökat. Syftet med denna studie är att analysera hur intressenters hållbarhets förväntningar kan främjas och uppnås under ett byggnadsprojekts livscykel och relaterat till byggnadsprocess steg genom att stödja projektledaren med användning av ett specifikt designat visuellt verktyg. Detta kommer att undersökas genom att svara på tre forskningsfrågor föreslagna i introduktionskapitlet (sida 5). Det visuella verktyget är skapat med fokuset på att definiera och etablera hållbarhets parametrar baserat på intressenters förväntningar. Verktyget ska kunna tillämpas på en mängd olika byggnadsprojekt med olika fokus på intressenters förväntningar. Ett teoretiskt ramverk har utvecklats som del av analysen baserat på redan existerande teorier; Business Model Canvas (Osterwalder & Pigneur, 2010), Global Performance Framework (International Civil Aviation Organization, 2009) och Intressentmodellen. Det föreslagna ramverket och dess visuella verktyg som utgör en av dess komponenter, är ett sätt att stödja en projektledare med intressentkommunikation, samverkan och informerat beslutsfattande. Det visuella verktyget har anpassats till att inkludera ett gemensamt språk och struktur för att förbättra kommunikation och samarbetet bland nyckelintressenter och stödja en projektledare med att säkerställa att ett byggprojekt har som fokus att uppnå förväntade hållbarhetsresultat.

Abstract (sommario):

La ricerca di una produzione sostenibile passa attraverso la comprensione dell'intero ciclo di vita del prodotto/servizio oggetto di analisi. In questo contesto, il presente elaborato mostra due metodi utili alla valutazione degli impatti ambientali di un sistema produttivo: la Sustainable Value Stream Mapping e il Life Cycle Assessment. Il framework proposto è in grado di visualizzare e valutare le prestazioni del processo di produzione/servizio dal punto di vista della sostenibilità, andando ad indagare su più aspetti (ambientali e sociali). l contributo chiave è l'integrazione fra i due metodi sopra citati. Il quadro proposto è esplicitato attraverso un caso studio presso l'azienda Arcese Trasporti S.p.a., in cui si è analizzato il servizio logistico che l'azienda offre ai suoi clienti. Si è svolta una mappatura del flusso delle merci e una modellazione di tale situazione attraverso il software Simapro 7.3.3, al fine di estrapolare indici ambientali da attribuirli ad ogni fase del processo. I risultati di tale modellazione si sono concentrati principalmente sulla categoria Climate Change, sull'impatto dei diversi materiali, sull'utilizzo di energia e infine sull'impatto che politiche di riuso hanno sulle emissioni.

Abstract (sommario):

Sequestering carbon in standing biomass, using woody bioenergy, and using woody products are the three potential ways to utilize forests in reducing greenhouse gases (GHGs) and mitigating climate change. These forestry related strategies are, however, greatly influenced by the existing markets and market based policies. This study focuses on the first two forest strategies. It investigates the combined impact of carbon and woody bioenergy markets on two different types of forests in the US – oak dominated mixed hardwood forests in the Central Hardwood Forests Region and loblolly pine forests in the southeastern US. A modification of the Harman model was used for the economic analysis of carbon sequestration and harvesting woody biomass for bioenergy. A forest carbon life-cycle assessment was used to determine the carbon emissions associated with management of forests and harvesting of wood products. Results from this study indicate that carbon payments and woody bioenergy production increase the land expectation value (LEV) for both forest types.

Abstract (sommario):

A novel microstructure-sensitive extreme value probabilistic framework is introduced to evaluate material performance/variability for damage evolution processes (e.g., fatigue, fracture, creep). This framework employs newly developed extreme value marked correlation functions (EVMCF) to identify the coupled microstructure attributes (e.g., phase/grain size, grain orientation, grain misorientation) that have the greatest statistical relevance to the extreme value response variables (e.g., stress, elastic/plastic strain) that describe the damage evolution processes of interest. This is an improvement on previous approaches that account for distributed extreme value response variables that describe the damage evolution process of interest based only on the extreme value distributions of a single microstructure attribute; previous approaches have given no consideration of how coupled microstructure attributes affect the distributions of extreme value response. This framework also utilizes computational modeling techniques to identify correlations between microstructure attributes that significantly raise or lower the magnitudes of the damage response variables of interest through the simulation of multiple statistical volume elements (SVE). Each SVE for a given response is constructed to be a statistical sample of the entire microstructure ensemble (i.e., bulk material); therefore, the response of interest in each SVE is not expected to be the same. This is in contrast to computational simulation of a single representative volume element (RVE), which often is untenably large for response variables dependent on the extreme value microstructure attributes. This framework has been demonstrated in the context of characterizing microstructure-sensitive high cycle fatigue (HCF) variability due to the processes of fatigue crack formation (nucleation and microstructurally small crack growth) in polycrystalline metallic alloys. Specifically, the framework is exercised to estimate the local driving forces for fatigue crack formation, to validate these with limited existing experiments, and to explore how the extreme value probabilities of certain fatigue indicator parameters (FIPs) affect overall variability in fatigue life in the HCF regime. Various FIPs have been introduced and used previously as a means to quantify the potential for fatigue crack formation based on experimentally observed mechanisms. Distributions of the extreme value FIPs are calculated for multiple SVEs simulated via the FEM with crystal plasticity constitutive relations. By using crystal plasticity relations, the FIPs can be computed based on the cyclic plastic strain on the scale of the individual grains. These simulated SVEs are instantiated such that they are statistically similar to real microstructures in terms of the crystallographic microstructure attributes that are hypothesized to have the most influence on the extreme value HCF response. The polycrystalline alloys considered here include the Ni-base superalloy IN100 and the Ti alloy Ti-6Al-4V. In applying this framework to study the microstructure dependent variability of HCF in these alloys, the extreme value distributions of the FIPs and associated extreme value marked correlations of crystallographic microstructure attributes are characterized. This information can then be used to rank order multiple variants of the microstructure for a specific material system for relative HCF performance or to design new microstructures hypothesized to exhibit improved performance. This framework enables limiting the (presently) large number of experiments required to characterize scatter in HCF and lends quantitative support to designing improved, fatigue-resistant materials and accelerating insertion of modified and new materials into service.

Abstract (sommario):

Trends such as globalization, increased customer demands and the increased sustainability challenge are forcing medium sized manufacturers to rethink their production processes and start developing lean and sustainable production systems.Many of the developed tools and methods for the lean and sustainable production presented in the literature are not well suited for medium sized manufacturers with a lack of empirical case studies, and therefore investigating suitable approaches for improving the production and sustainability performances is needed in their case. This thesis proposes to use a mixture of tools from both the Lean and sustainable development literature for creating a lean and sustainable production roadmap for medium sized manufacturers. It demonstrates a case study conducted at a medium sized roller blind manufacturer who is preparing to introduce lean and enhancing their sustainability at the production to cope with the condensed market and their customer requirements. The study analyzes the manufacturing processes from both the lean and sustainability perspectives, where different tools were adopted and used throughout the work, which are: Value Stream Mapping, Sustainable Life Cycle Assessment, and Sustainability Compliance index, with the data collected through interviews, dialogues, observations, time studies and internal documents. Understanding the company specific problems and value acted as a foundation for further analysis and improvement potentials identification to reach a future lean and sustainable state in the production, which resulted in enhancing the firm´s lean and sustainability performances. This thesis complement the lean initiatives with a sustainability assessment effort to grasp the whole picture and generate ultimate improvement potentials in order to cope with today´s evolving trends and the increased sustainability requirements. A main contribution is the developed guidelines for creating a lean and sustainable production roadmap for medium sized manufacturers, which result in leveraged benefits satisfying both the lean and sustainable needs.
Trender såsom ökad globalisering, nya kundkrav och ökade utmaningar inom hållbarhet, leder till att medelstora tillverkningsföretag tvingas att tänka om gällande produktionsprocesser och börja utveckla koncept inom lean och hållbar produktion.Många av de utvecklade verktygen och metoderna inom lean och hållbar produktion, som återfinns i litteraturen, är inte väl lämpade för medelstora tillverkningsföretag och saknar empiriska fallstudier. Detta motiverar till vidare analys kring lämpliga metoder för att öka prestationen inom produktion och hållbarhet för dessa företag. Denna uppsats går igenom de olika verktyg som finns definierade i litteraturen, både ifrån lean och hållbarhetsutveckling, och föreslår en väg framåt för att skapa en optimerad och hållbar produktion för medelstora tillverkningsföretag.Denna uppsats demonstrerar en fallstudie utförd på en medelstor rullgardinstillverkare som är beredd att introducera lean och öka deras hållbarhetsperspektiv i produktionen. Detta för möta den mättade marknaden och deras kundkrav. Studien analyser tillverkningsprocesserna från både lean och hållbarhetsperspektiv, där olika verktyg har blivit anpassade och testade under hela processen (Value Stream Mapping, Sustainable Life Cycle Assessment och Sustainability Compliance index). Uppgifterna som använts har samlats in genom intervjuer, dialoger, observationer, tidsstudier och intern dokumentation. Förståelse av företagets specifika problem gav en grund för vidare analys, där förbättringspotentialer identifierades för att nå ett framtida lean och hållbarhetsperspektiv i produktionen. Uppsatsens resultat bidrog till reella förbättringar för företaget inom området. Denna uppsats drar slutsatsen att komplettering utav lean initiativ med hållbarhetsutvärdering är nödvändigt för att få fram en helhetsbild kring en optimal förbättringspotential. På så sätt kan företagen bättre klara av dagens nya trender med ökade hållbarhetskrav. De utvecklade riktlinjerna för att skapa en lean och hållbar produktion i ett medelstort tillverkningsföretag resulterar i fördelar som uppfyller kraven både från ett lean och i hållbarhetssynpunkt.

Abstract (sommario):

Urbanization involves the conversion of natural areas to impervious surfaces, which can lead to an increase in the frequency and severity of flood events in cities. To mitigate flood risk, stormwater ponds are constructed to manage urban runoff. Stormwater ponds can also be colonized by wildlife, but their suitability as habitat is disputed due to potential toxicological risks. This study assessed the suitability of stormwater ponds as habitat for the bioindicators Odonata (dragonflies and damselflies) and determined environmental factors that impact their community structure. Odonata (adults, nymphs and exuviae) were sampled at 41 stormwater ponds and 10 natural reference ponds across the National Capital Region of Canada, with a subset of ponds sampled over four years (2015-2018). Plant communities, water quality and surrounding land cover were analyzed at each pond to determine their impacts on Odonata community structure. Overall, stormwater ponds had lower Odonata abundance and a greater variation in species richness and community structure compared to natural ponds but had comparable dragonfly reproduction rates. Plants were the most significant driver of Odonata communities, as stormwater ponds with a high richness of native wetland plants had higher Odonata abundance and community structures similar to natural ponds. Water quality was the second most important driver of Odonata communities with dragonflies showing greater sensitivity to urban contaminants than damselflies. While stormwater ponds had higher concentrations of trace elements than natural ponds (e.g. Ni, V, As), concentrations were generally below toxic levels for all elements except copper and chloride, the latter likely an input from winter road salting. Surrounding land cover was the least important factor affecting Odonata communities. In conclusion, this research demonstrated the importance of local-scale factors related to plants and water quality in sustaining Odonata communities and specifies recommendations for stormwater pond design and maintenance that enhance urban biodiversity.

Abstract (sommario):

Charnov's (1976) marginal value theorem has had success in predicting that animals will optimize net rate of gain when foraging in a patchy environment. The present study attempts to apply the marginal value theorem (MVT) to human behavior in a business setting in 3 Experiments. Businesses also attempt to optimize net rate of gain when choosing to discontinue one product in lieu of another using a product life cycle (PLC). Experiments 1 & 2 attempted to assess human behavior in a business context by varying time necessary to retool and monetary cost of retooling respectively. Experiment 3 attempted to add ecological validity by introducing variability to the PLC. The results of Experiments 1, 2, & 3 indicate that the MVT does not accurately predict human behavior in a business context, though methodological issues may have affected these results. Future research must be conducted in this area.

Abstract (sommario):

With many research available on IT governance, this research differs from most of them due to its delimitation. The focus of this research lies in the two domains of value creation and performance measurement. Furthermore, the area of research has been small and medium Enterprises located in the area of Småland, Sweden. Brisebois, Boyd & Shadid (2001) gave us the following definition of IT governance: “How those persons entrusted with governance of an entity will consider IT in their supervision, monitoring, control, and direction of the entity. How IT is applied will have an immense impact on whether the entity will attain its vision, mission, or strategic goal.” An objective of IT governance is to align the IT resources of an enterprise in a way that it fast-tracks the business priorities of the enterprise and assures that the investments in IT generates business value and that the IT is performing to its expectations. The research questions and the outcome of this research paper sheds light on the challenges of both value creation and performance measurement within the SMEs, but it also showcases what the driving forces of IT value creation are and which benefits arise from measuring the IT performance within the SMEs. Through semi-structured interviews with four SMEs, based in the region of Småland, numerous amounts of challenges and driving forces for IT value creation and challenges and benefits to measuring IT performance have been extracted. Based on the extracted information from the interviews, an analysis and a conclusion have been formed by the authors. In the end, the authors provide their thoughts for suggestions for further work and how all of this contributes to the field of Informatics.

This study aims to investigate value-relevant information provided by intellectual capital (IC) beyond financial performance for information technology companies in the different life cycle stages and stages of value chain. The empirical results show that the value-relevant information provided by IC under the growth, maturing, and stagnant stages can be ranked in order (from high to low) of custom, innovation, process, and human capital. Specifically, the empirical results indicate that overall IC provided the most value-relevant information in the stagnant stage and the lowest value-relevant information in the growth stage. These results also clearly show that the value-relevant information of the overall IC for the midstream companies is higher than that for the upstream and downstream companies. If each IC is compared, the innovation capital provides the most value-relevant information for companies in the upstream section, the human capital provides the most value-relevant information for companies in the midstream section and the customer capital provides the most value-relevant information for companies in the downstream section. In this study, a model which linked R&D investment, R&D capability, and financial performance to company market value was also developed. For companies in the different life cycle stages and stages of value chain, there are two basic differences across stages and sections: (1) the relationship between financial performance and market value and (2) the relationship between R&D capability and market value. In spite of these differences, there are also important similarities across the three stages and sections. That is, two of the four paths are significant and are in the hypothesized direction for the three sections: (1) the effect of R&D investment on R&D capability and (2) the effect of R&D capability on financial performance.

In the modern knowledge economy, intangible assets has become the high proportion of enterprise value, brand value is also an unrecorded intangible assets. Value relevance of corporate brand value in Taiwan, previous studies have not yet been discussed extensively. Therefore, this study examines the association of the brand value and stock price, and additional consider the corporate life cycle factors to investigate whether the value relevance of brand value at various stages of life cycle is different. This study use the Taiwanese international brands company as sample, released by Taiwan Interband website from 2003 to 2011, and this paper use Ohlson model to test the value relevance of the brand value. Finally, this study employ the Anthony and Ramesh’s (1992) method to divide sample to different corporate life cycle stage. The empirical results show that there is a significant positive relationship between brand value and share price. After considering the life-cycle factors, the value relevance of brand value at the growth phase higher than the maturity and recession stage. However, the value relevance of brand value was no significant different between mature and recession stage.

This paper uses monthly sample from June 1994 to 2007 June. We use the book-to-market spread (the book-to-market of value stocks minus the book-to-market of growth stocks), the market-to-book spread (the market-to-book of growth stocks minus the market-to-book of value stocks) and value spread (log book-to-market spread minus log market-to-book spread) to predict stock returns. In addition, we use two ways (business cycle date and the bull and bear) to classify sample period. The empirical evidences show that when the returns of value stock and growth stock are dependent variable, the book-to-market spread predicting future returns with a negative sign, the market-to-book spread predicting future returns with a negative sign and the hypothesis of value spread with weak predictive power for future returns was supported. It is found that the relationship of business cycle and value spread is negative and the relationship of the bull and bear and value spread is not obvious.

The magazine industry operates on a scale of more than 25 billion NTD per annum in Taiwan. In recent years, the proliferation of broadband Internet and an increase in Internet users have altered the methods and means by which consumers receive information. Faced with the challenges and opportunities brought about by the Internet, magazine publishers have attempted to incorporate their content onto the Internet in various ways, but the effects have been fairly limited. Analysis conducted in accordance with “The Long Tail” concept suggests that there is a market for past issues of magazines, but currently, a suitable means of accessing them does not exist yet. By integrating three forces of “Long Tail”, a market for past issues of magazines can be established. Research done for this paper reveals that by utilizing three key elements: past issues, paper copy scans, and subscription model, Internet platforms will be able to cooperate with magazine publishers and place content on the Internet. By practicing the Creative Value Creation Cycle’s framework, along with applying the three key elements: surf by units, search by keywords, and deliver content of past issues to the Internet, a different magazine industry value chain can be established. Actualization took place in April, 2008. Initially participation consisted of 50 magazines, but the number of participants is rapidly increasing. In terms of the Taiwanese market, revenue per annum is projected to reach 600 million NTD, with more than 500,000 subscribers. In the future, this platform will be able to combine forces with magazine publishers to enter the Internet advertisement market and create an entirely different magazine industry value chain. The closing conclusions of this paper are: 1. Paper magazines experience a “Long Tail” effect through digitalization. 2. Through digitalization, magazine content will be able to reach new readers and new markets. 3. A completely creative magazine industry value chain can be established through the Internet. Key word: Internet, Magazine, Long Tail, Creative, Value Chain, CVCC

Adopting Cash Flow Patterns (Dicksion, 2011) as a Proxy for Firm Life Cycle. The samples of this paper are from Taiwanese publicly traded companies, including the Taiwan Stock Exchange (TSE) and the computerized over-the-counter market (OTC) during 2008 to 2013. To deal with multicollinearity of cross-product term, using ridge regression reduces the standard errors. The empirical results that there’s no significant relationship between brand value and enterprises value totally, but there’s a positive significant relationship between brand value and enterprises value after add in introduction and shake-out enterprises life cycle periods. This indicated that the brand value is significant to improve the informativeness and the value relevance of financial statements at enterprise value in two stages.

In recent years, the hottest technology is “Blockchain”, and the corresponding applications are gradually flourishing in daily life. In spite of its great fame and many application scenarios, blockchain is still often misunderstood as narrow “Bitcoin”, or even hackers'' illegal transaction ways. That’s all because blockchain technology is too crude and difficult to understand. In fact, the characteristics and services provided by blockchain technology are far less than this, and there are many advantages that can be referred. The most worth mentioning is Ethereum. Therefore, this paper will systematically discuss the “Ethernet type” blockchain and answer the following questions: (1) Whether the business model of “Publicly Applied Blockchain” valuable or not (2) Analyze and summarize whether characters in “Publicly Applied Blockchain” industry have a positive value creation cycle or not (3) Make amendments and suggestions to the shortcomings of “Publicly Applied Blockchain” and provide opinions and ideas for future industry entries At the end of this study, I’ll analyze this industry from a macro perspective using Value Creation Cycle (VCC) to ensure that the positive value will be continuously fed back into the cycle and create value.

Thanks to the development of the Internet and the mobile devices, people tend to share information and knowledge and keep in touch with one another via the Internet. Hence in such generation, there are more and more businesses that aim to build platforms which allow people to share their idle, or residual, assets or capacity on the market and thus create values. Uber, Inc., the famous ride-sharing company, and Airbnb, Inc., the popular housing service company, both are classic example of sharing economy. Through the analysis on such kind of company cases, this research aimed to firstly, clearly define sharing economy and its core values, and secondly, analyze its VCC (Value Creation Cycle) and generate the key factors that drive the cycle to flow. 　　First of all, this research began with reviewing articles of sharing economy and the case companies, and then clarified the scope of the research. There are two parts of this research. In part one, it defined the nature of sharing economy, analyzed the system elements, modeled the trading activities, and then concluded the characters and core values of sharing economy. In part two, based on the model and core values derived from the part one, it depicted the Value Creation Cycle of sharing economy which could offer to overlook the whole value chain. Following the cycle model, it was analyzed with the micro perspective as a trading cycle, with the macro perspective as a strategic cycle, and finalized with the key factors that maintain the positive cycle of the VCC. 　　Given that sharing economy has the characters of the presence of idle or residual resources and a platform that links the demand and the supply, this research had concluded that sharing economy has three core values, which are activating idle resources to create excess revenue with low price, low using costs and entrance barriers, and the flexibility of time and space. These three values circulate in the trading cycle and keep saving the market momentum, enabling the strategic cycle start at users'' insight then formulate the vision even practice it when it comes to the design stage. However, since the resources in sharing economy are owned by unfamiliar others, instead of usual businesses, sharing economy users are less likely to trust the providers. Thus, in addition to reviewing if each stage of VCC aligned with the vision as well as strategies and then generates the positive cycle, to attain enterprise''s goal of sustainability, platforms should aim to maintain the positive cycle of VCC by means of risk management like identification authentication, ratings and feedbacks, and commitment of compensation.

Abstract (sommario):

Agricultural census data have been identified to possess the potential to provide constraints on carbon uptake by croplands at the regional scale. In this study, we build on previous efforts and further assess this potential quantitatively by comparing 1) fractional cropland coverage in southwestern Ontario, Canada derived from agricultural statistics against three different remotely sensed land cover maps; and 2) carbon uptakes determined from agricultural data with simulations generated by a satellite data-driven biospheric model. In addition, we assimilated the census data-derived carbon uptakes with modeled estimates in a Bayesian inverse approach to determine if and by how much constrain the crop data can provide, as exhibited by uncertainty reductions. Uncertainties in census data-derived gross primary production (GPP) estimates are carefully quantified using a Monte Carlo simulation. In general, results from the fractional cropland coverage comparison indicate significant value of the agricultural census data by revealing biases in the spatial distribution of croplands, as found in all three of the satellite land cover products. However, we find that the carbon uptake values derived from crop harvested records are still subject to significant uncertainties that have been underestimated or neglected altogether in past studies. The Monte Carlo simulation suggests that the largest source of uncertainty can be traced to errors in the growth efficiency, followed by harvest production records, and then the harvest index. As result, attention must be paid to such errors when using the agricultural census data for carbon accounting purposes or to provide constraints to simulations of crop carbon uptake.

The study analyzed 523 strategic alliances in Taiwan electronics industry formed during the period 2001-2005. Using event study methodology, we found that announcements of strategic alliances from different life cycle stage firms enjoyed different abnormal returns in the stock market. In addition, consistent with our expectation, abnormal returns were positively correlated with firms with cluster effect and alliance forms, indicating that investors perceived to be more profitable, furthermore, firms with cluster effect captures more of the gain generated in alliance. Indeed, the firms in different life cycle stages and different alliances appeared to affect the investors’ expectation.

Using Ohlson model, this study examines the relationship between corporate governance and equity market value in different corporate life cycle stages from the following corporate governance perspectives respectively: board structures, ownership structures, managerial types and the information transparency. This study covers the listed firms from 2005 to 2008. Cross-sectional analyses are performed with and without controlling for individual firm’s corporate life stages. The empirical results are as follows: (1) Without considering corporate life cycle stages, management ownerships and institutional ownerships relate significantly to the equity market value, while management ownerships and directors and supervisors’ ownerships have significantly negative association with the equity market value. On the other hand, board size, block holders’ ownerships, duality and transparency associate insignificantly with equity market value. (2) Taking corporate life cycle stages into consideration, board size, management ownerships, institutional ownerships, pledged shares of insider ownership and duality have the most significant association with equity market value for the growth stage. But there are not any significant differences in the relationships between equity market value and directors and supervisors’ ownerships and transparency for the three corporate life cycle stages.

In China and many countries in Asia, E-commerce has become one of the most competitivefields in Internet industry. It draws the eyes of all the players in the traditional retailing supply chain. Suppliers, regardless of scales, are all eager to sell their products online. The trend creates many platforms and B2C online shopping companies. However, does the difference between e-commerce and traditional retailinglie only in their channels? Is there any way for potential players who want to enter this competitive environment to survive? This thesis attempts to reduce online shopping to the most seen type: low-priced female online shopping, whose products may include fashionable clothes, shoes, purses and bags.This thesis then tries to analyze its model and problems. This research also discovers how to use e-commerce''s characteristic of native website to combine and take advantages of features which only a website has.
