The research was aimed at addressing the challenge of evaluating a large scale change intervention in a large organisation and in a complex environment. Finding robust, meaningful yet realistic methodologies from among the array of possible approaches, methods and techniques has proved problematic, for both organisational practitioners and academics alike. The research explored this issue of choice from the perspective of 'fit for purpose' and suggests a multi-faceted approach, using a range of evaluation methods and techniques, which were applied to an ongoing example at the BBC. It was also planned to use structural equation modelling (SEM) techniques to examine the relationships between variables critical to the study. The approach described represents a 'pilot' evaluation exercise, which drew on data collected from early cohorts going through the BBC Leadership Programme, a key element of the 'Making it Happen' change strategy initiated by the then Director General, Mr. Greg Dyke. As a second level of research, an evaluation of the primary evaluation itself, i.e. of the BBC Leadership Programme, was also undertaken to assess the effectiveness of the primary evaluation strategy and its implementation. Three hypotheses were examined in terms of programme impact: It was proposed that participation in the programme would bring about collective improvements in individual leadership behaviour (Ho1), leading to improved departmental performance across the business (Ho2), in turn, resulting in improved organisational performance (Ho3). Due to limitations in the application of the methodology it was not possible to use SEM analyses on the data collected. Alternative analyses failed to demonstrate conclusive support for all three hypotheses and, while other factors besides programme attendance appear to influence leadership performance the afore-mentioned limitations restrict the ability to draw firm conclusions. Following evaluation of the primary evaluation it was evident that, as a pilot exercise, important outcomes from the programme evaluation give rise to 'lessons learned' and changes are suggested for any future evaluation exercise of this kind.

The aim of this thesis is to evaluate ORC systems and technologies from an energy and economic perspective. ORC systems are a growing renewable electricity generation technology, but New Zealand has limited local skills and expertise for identifying ORC resource opportunities and subsequently developing suitable technologies at low cost. For this reason, this thesis researches ORC technology, resource types, and international development, with the aim to determine guidelines for how to cost-effectively develop ORC systems, and to make recommendations applicable to furthering their development within a New Zealand context. This thesis first uses two surveys, one of commercial ORC installations, and a second of economic evaluations of ORC systems in literature, to determine what resources and economic scenarios are supportive of commercial development. It is found that geothermal resources provide the largest share of ORC capacity, with biomass and waste-heat recovery (WHR) being developed more recently. The surveys also found that countries with high electricity prices or policy interventions have developed a wider range of resources using ORC systems. This thesis then undertakes an EROI evaluation of ORC electricity generation systems using a combination of top-down and process based methodologies. Various heat sources; geothermal, biomass, solar, and waste heat are evaluated in order to determine how the utilised resource can affect energy profitability. A wide range of EROIstnd values, from 3.4 – 22.7 are found, with solar resources offering the lowest EROIs, and geothermal systems the highest. Higher still EROI values are found to be obtainable with longer system lifetimes, especially for WHR systems. Specific engineering aspects of ORC design and technology such as high-side pressure, heat storage, modularity, superheating, pinch-point temperature difference, and turbine efficiency are evaluated in terms of economic performance, and a variety of general conclusions are made about each. It is found that total system thermo-economic optimisation may not lead to the highest possible EROI, depending on the objective function. Lastly, the effects of past and potential future changes to the markets and economies surrounding ORCs are explored, including the New Zealand electricity spot price, steel and aluminium prices, subsidies, and climate policy. Of the subsidy types explored, it is found that directly subsidising ORC system capital has the greatest effect on the economic performance of ORC systems, as measured by common metrics. In conclusion, this thesis finds that ORC systems have a limited applicability to New Zealand’s electricity market under current economic conditions outside of geothermal and off-grid generation, but changes to these conditions could potentially make their development more viable. The author recommends that favourable resources should be developed using systems that provide high efficiencies, beyond what might provide the best economic performance, in order to increase EROI, and reduce the future need for costly investments into increasingly less favourable resources.

I will also examine the brand value, potential clients’communication channels, and customer loyalty maintenance created by traditional and online marketings, as well as the possible ramifications of ever-changing marketing mediums. Can these marketing models effectively and efficiently increase profit, build customer relations and loyalty, and decisively influence the management of brand image? The world-wide-web has not only impacted traditional marketing, but has become the preferred communications, and unlike the traditional, it provides borderless information exchange and real-time feedback for comprehensive performance evaluation. As companies mature in their use of the world-wide-web, they are able to utilize the internet to communicate with customers to foster an efficient and effectual interaction. Main conclusions are as follows: both projects suggest that integrated marketing communications continue to change with market systems, and directly influence the number of customer visits and the rate of conversion. Online marketing is inexpensive in contrast to the traditional, and is much easier to track for return-on-investment analysis, thereby allowing for more rapid change of advertisement slots according to performance, raising the responsiveness and return. Online marketing communication can be customized to appear more personal and achieve better customer relations, which in turn increases brand loyalty and referral rate.

This paper presents a method to value the residential real estate portfolio of an economy by summarizing the future discounted values of the net operating income. The motivation for this choice of subject is the concern for a house bubble in Sweden due to the double-digit rise in housing prices which the economy has experienced during many consecutive years. However, the method is general and can be applied anywhere where relevant statistics is available. The challenge to use an income approach to residential real estate valuation lies in the fact that there is no obvious net operating income, as the owner and the end user is in many cases the same person. To solve this challenge, we determine the maximum possible net operating income by taking the households’ disposable incomes and subtracting their expenses. This will be a fictional value for the maximum possible net operating income or the imputed income for real estate owners. When this fictional net operating income is compared to the mean prices of properties, a maximum potential yield to capital invested in residential real estate is extracted. The current number for this maximal potential yield on the Stockholm market seem to be 6,4 percent, 2017. The main contribution of this paper to the science of economy is that it presents a way to use classical fundamental valuation methods to evaluate the price level of residential real estate, that, due to lack of tangible net operating income is not as straightforward as the valuation of the commercial real estate market.

For more than three decades, the World Economic Forum’s annual Global Competitiveness Reports have studied and benchmarked the many factors underpinning national competitiveness. The quality of higher education and training is considered particularly crucial to ensure national competitiveness. The globalizing economy requires countries to nurture pools of well-educated workers who are able to perform complex tasks and adapt rapidly to their changing environment and the evolving needs of the economy. Vocational and continuous on-the-job training and the constant upgrading of workers’ skills is critical to sustain the economical status of the country. Despite the acknowledgement that education, training and development (ETD) is a key driver for a country's economical sustainability and growth, the contributions that companies make to this effect are a concern. This is ascribed to the difficulties experienced in companies regarding the management of ETD. In this study it is postulated that communication problems are at the heart of the challenges which are experienced in managing ETD. Strategic conversation is proposed as one of the methods to address the communication and performance shortcomings experienced by business and ETD managers. It is argued that if the level of conversations is raised to make them strategic, the potential to optimise results and make an impact at organisational and national level is increased. Hence, the purpose of this study was to propose a Strategic ETD Conversation (SETDC) model to optimise Return on Occupational Training Expectations (ROTE) that would contribute towards the achievement of organisational and national strategic goals. In lieu of the limited empirical research available on the strategic conversation phenomenon in general, the purpose of this study was inter alia to conduct empirical research to explore the essence of strategic ETD conversations in order to propose a model of practical value to ETD managers. Hence, the empirical research was situated in both an explorative paradigm and a pragmatic paradigm with the aim to provide practical solutions and an instrument to successfully engage in strategic ETD conversations which would enhance the quality of ETD and thus contribute to global competitiveness. / Educational Leadership and Management / D.

The economic value creation is something that affects all companies, that is why, it is crucial to establish , for which purpose, there are a variety of procedures. Among which, especially the method of economic value added (EVA), which can compare the yield of investment to its financial cost. This methodology is very useful, but its definition does not distinguish EVA from the business effects with EVA generated results, so in this article we propose a new way to determine the EVA that allows differentiation and the EVA distinction created by many results achievable by the company. Finally, an explanatory case it is presented to demonstrate if the new proposal it is applicable or not. / La creación de valor económico es el norte que mueve a toda empresa, por lo tanto, es crucial establecer su valor económico, para lo cual existe una diversidad de procedimientos. Entre todos ellos, destaca el método del valor económico añadido (VEA), el cual tiene la virtud de comparar el rendimiento de la inversión con su costo de financiamiento. La propuesta metodológica es de mucha utilidad, pero en su delimitación no permite distinguir el VEA proveniente de los efectos del negocio con los VEA generados por otros resultados, por lo que en este artículo se plantea una nueva forma de determinar el VEA que permite diferenciar y distinguir los VEA creados por los diversos resultados que podría obtener la empresa. Por último, se presenta un caso explicativo que permite demostrar la aplicabilidad de la nueva propuesta.

Abstract Most of the steel produced in the world is based on the integrated blast furnace-converter route, which is based on the use of virgin raw materials. Large amounts of fossil-based, carbon containing reductants are used in blast furnaces, which results in carbon dioxide emissions into the atmosphere. Fossil carbon dioxide emissions from steel production can be reduced by new technologies or moving from non-renewable to renewable energy sources. Biomass-based reductants could be one way to reduce the specific emissions from blast furnace-based steel production. The aim of this thesis was to examine the techno-economic and CO₂ mitigation potentials of using bioreducers in blast furnace ironmaking. Bioreducer feasibility was analyzed in the Finnish context, but the research methods used can be applied more widely. The metallurgical properties of bioreducers were evaluated and compared to fossil-based reductants. The impact of bioreducers on blast furnace behavior and on other steel plant processes was evaluated, with an emphasis on the reductions achieved in CO₂ emissions at the plant scale. The CO₂ emissions, energy consumption and production costs of bioreducers were evaluated, as was the availability of energy wood for bioreducer production. The results show that solid, liquid and gaseous bioreducers can be produced with thermochemical conversion technologies. However, their suitability for blast furnace use varies greatly. The highest substitution of fossil-based reductants in a blast furnace is achieved with charcoal injection. The carbon footprint of torrefied wood, charcoal and Bio-SNG is moderate compared to fossil-based reducing agents and their production is energetically feasible. The economic feasibility of bioreducers is currently weak in comparison to fossil-based reducing agents, but competitive when compared to other CO₂ emission reduction measures such as carbon capture and storage. The biomass availability assessment revealed that sufficient amount of energy wood could be available for bioreducer production in the areas where Finnish steel plants are situated. The feasibility of bioreducer production could be improved by producing a number of products from the biomass and taking advantage of the process of integration possibilities. / Tiivistelmä Suurin osa maailmassa tuotetusta teräksestä valmistetaan integroidulla masuuni-konvertteri reitillä, joka perustuu neitseellisten raaka-aineiden käyttöön. Masuuniprosessissa käytetään suuri määrä fossiilisia, lähinnä hiilipohjaisia pelkistimiä, jotka aiheuttavat hiilidioksidipäästöjä ilmakehään. Fossiilisia hiilidioksidipäästöjä voidaan teräksenvalmistuksessa vähentää uusilla teknologioilla tai siirtymällä uusiutumattomista energialähteistä uusiutuviin. Biomassasta valmistetut pelkistimet voisivat olla yksi mahdollinen keino alentaa masuunipohjaisen teräksenvalmistuksen ominaispäästöjä. Tämän työn tavoitteena oli tarkastella biopelkistimien käytön teknistaloudellista potentiaalia masuunikäytössä ja aikaansaatavia hiilidioksidipäästövähenemiä eri systeemirajauksilla. Työssä keskityttiin tarkastelemaan biopelkistimien hyödynnettävyyttä lähinnä Suomen tasolla, vaikka käytetyt tutkimusmetodit ovat sovellettavissa myös laajemmin. Työssä arvioitiin biopelkistimien metallurgisia ominaisuuksia, niiden vaikutusta masuuniprosessiin ja laajemmin muihin terästehtaan prosesseihin, pääpainon ollessa saavutettavan CO₂ päästövähenemän tarkastelussa. Työssä tarkasteltiin biopelkistimien valmistuksen CO₂ päästöjä, energiankulutusta ja tuotantokustannuksia sekä energiapuun saatavuutta biopelkistimien tuotantoon. Tulokset osoittavat, että biomassasta voidaan valmistaa kiinteitä, nestemäisiä ja kaasumaisia pelkistimiä termokemiallisilla konversioteknologioilla, joiden soveltuvuus masuunikäyttöön vaihtelee suuresti. Masuuniprosessissa suurin fossiilisten pelkistimien korvaavuus saavutetaan käyttämällä puuhiili-injektiota. Torrefioidun puun, puuhiilen ja Bio-SNG:n hiilijalanjälki on varsin maltillinen verrattuna fossiilisiin pelkistimiin ja niiden tuotanto on energeettisesti järkevää. Biopelkistimien taloudellinen kannattavuus verrattuna fossiilisiin pelkistimiin on tällä hetkellä heikko, mutta kilpailukykyinen verrattuna muihin CO₂ päästöjen vähennyskeinoihin, kuten hiilidioksidin talteenottoon ja -varastointiin. Energiapuun saatavuus biopelkistimien valmistukseen on suurin alueilla, jotka sijaitsevat lähellä Suomen terästehtaita. Biopelkistimien tuotannon kannattavuutta voitaisiin parantaa tuottamalla useita tuotteita ja hyödyntämällä prosessi-integraatiota.
