Hochstetler, Jay J. "Revising the Volunteer Functions Inventory| An Exploratory Study of Additional Functions." Thesis, Northcentral University, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=3578565.
Full textAbstract:
Volunteers provide valuable human resource assets in many areas of society and are critical to the success of non-profit organizations. The Volunteer Functions Inventory (VFI) has been used for over ten years and has received the most attention from researchers who cite the theoretical basis, the predictive nature, and the general purpose application of the inventory as major strengths. However, there are several shortcoming of the instrument which limits its value to organizations that use volunteers. Several researchers have suggested that additional functions should be included in the VFI. The purpose of this qualitative study was to identify missing functions that should be part of this inventory in order to improve its effectiveness as a tool for identifying volunteer motivations. The problem was that the VFL is an incomplete survey of functions for volunteer motivations, which limits its usefulness to practitioners and researchers. This research study was a qualitative multiple case study analysis which included interviews with volunteers, informant feedback, and focus group review of the coding of excerpts. A total of twelve volunteers from three volunteer organizations were purposefully selected for maximum variation. Questions were field tested with four experts and the researcher conducted face-to-face interviews with each participant. Informant feedback was used to verify the transcription and the analysis of the results, and a focus group performed a sorting procedure to verify the results. The analysis supported use of the six functions included in the VFI, and found considerable support for the concepts of civic responsibility and debt or obligation as functions that provide motivation for volunteerism. There were a notable number of comments by the participants that aligned with these two functions, and were validated through the triangulation methods of participant feedback and the focus group. Based on this study, the researcher concludes that civic responsibility and debt or obligation are functions that should be included in the VFI. The researcher recommends that additional studies should be conducted to develop a modified VFI including these functions. This includes creating and validating questions for the two additional functions, and a testing and validating a revised inventory.

Full textAbstract:
One of the sectors within the tourism industry which is considered to be large and continuously expanding is the business tourism sector, also known as MICE tourism (meetings, incentives, conferences and exhibitions). Countries and cities rely heavily on investment in infrastructure to support the development of this sector and to ensure sustained growth, many destinations use destination management organisations (DMOs) and convention bureaus to provide leadership. These organisations are also tasked to actively promote the destination for leisure travel and it is necessary to understand the distinct requirements that set business tourism development and promotion apart from leisure tourism. This study employed multi-method qualitative research to investigate the roles and functions that DMOs perform in order to develop business tourism in a destination. This included understanding the challenges faced within varied destinations. Data was collected through interviews with a sample of nine major DMOs at various levels and four major conference centres across South Africa. Strategic documents and website content was also analysed as supplement to the primary data. The study shows the importance of especially DMO stakeholder engagement, marketing, identification of opportunities to host business tourism events within the destination, as well as bidding support as the main roles and functions that need to be performed to ensure sustained growth of business tourism. A framework is presented depicting the interaction between DMOs at the national, regional and local levels, as well as with the various industry stakeholders.Dissertation (MCom)--University of Pretoria, 2017.

Ill-health has been identified as the cause and consequence of poverty in Uganda. In April, 2009 the ICT4MPOWER project was launched in order to improve health care delivery in the rural communities of Uganda using Information and Communication Technology. One of the aspects considered, was the development of a human resource management system. Studying quality literature, interviewing possible stakeholders and investigating the current healthcare management information system led to the finding of both tactical and strategic functions for the development of human resources. Mock up interfaces was designed to support the needs of the organization. Flowcharts, use cases, and instruction films were made to clarify and to see the process from different end user. We have identified a need for a more strategic approach towards human resource management, but it must begin with establishing the hard foundation.

Teixeira, José M. "Contractors management functions : an integrated approach for planning, estimating and control." Thesis, Loughborough University, 1993. https://dspace.lboro.ac.uk/2134/12625.
Full textAbstract:
Planning, estimating and control management functions as performed by Portuguese construction companies were studied. For this purpose, inquiries were made into the way a set of Portuguese contractors carried out these tasks, with special reference to planning, estimating and the preparation of data for control during the pre-contract stage. There is a lack of integration among those functions in the current practice of companies surveyed. This is a problem that companies would like to see solved. Data systems analysis was used to tackle the problem. It was concluded that there is no functional dependency between planning and estimating in most construction projects. This is especially due to the form in which. data is structured in the basic documents currently used for those functions (the bill of quantities for estimating and the construction programme for planning). A possible integrated approach to planning and estimating is suggested by considering construction works assigned both to the items of the bill of quantities and to the activities of the construction programme. This facilitates the preparation of data for control on site because costs and time are closely related in this approach. A model for the integration of planning and estimating management functions during the pre-contract stage of construction projects is presented. The model also enables one to achieve efficient preparation of data for control on site. Computer support for the model is also presented. This is based on a Database Management System which provides for an adequate environment for the model. The model was tested in some Portuguese construction companies, and led to satisfactory results. Those companies highlighted the advantage of building up the model upon a relational database which makes data manipulation and retrieval easier and allows for integration among management functions.

MBA Professional ReportThis project describes the emerging approach of Complexity Management, translates it for use in the Department of Defense (DoD), and applies its principles to DoDb2ss financial functions. Complexity Management is a new business approach introduced by The George Group Consulting company. The basic principle behind this approach is the identification and manipulation of complexity to improve efficiencies and reduce cost in an organization. The ultimate goals for this project were to: b5s Analyze the Complexity Management approach, as presented by The George Group. b5s Evaluate the feasibility of applying the approach in DoD, in particular to its financial functions. b5s Determine if this new business approach would be useful in DoD. Most people would agree that DoD is an extremely complex organization due to its size, mission, and nature. As such, Complexity Management should be an imperative approach in its operations and a fundamental part of its culture. This project provides an introduction to Complexity Management and a discussion of the benefits DoD could achieve with this new business approach.

Fulgoni, Jessica. "Assessments of Midwestern Stream Restoration and Management Practices." OpenSIUC, 2018. https://opensiuc.lib.siu.edu/dissertations/1647.
Full textAbstract:
Ecological restorations have become increasingly important as humans have made irreversible changes to ecosystems; biogeochemical cycle alterations and land use changes have led to degraded conditions (Vitousek et al. 1997a). While some modifications to the environment are unavoidable, society is beginning to realize that changes are necessary. While some ecosystem functions may be beyond repair (e.g., biodiversity loss and extinction of species), it is important that the problem is faced head on and those functions that are still salvageable be restored. These environmental repairs can be done through ecological restoration. I looked at two different ecosystems, prairie streams and agricultural streams, that have undergone restoration to help functions. Patch-burn grazing (PBG) is increasingly used as a management practice on the few remaining tallgrass prairie parcels in an effort to simulate effects of large ungulate grazers. Yet, little is known about potential impacts and recovery of aquatic habitats from this management approach. My objective was to assess the influence of PBG with cattle on prairie streams and build on previous research at this site. I hypothesized that cattle grazing would negatively impact water quality and reduce stream biotic integrity, but riparian fencing would mitigate these impacts. We also assessed stream recovery for two years following the removal of ungulates from the study sites and hypothesized that biological and chemical effects would reverse. Six headwater streams (two controls, two PBG with 10 m fenced riparian zones, and two PBG with unfenced riparian zones) on Osage Prairie, Missouri, were sampled over seven years (2009-2015) encompassing pre-PBG (2 years), PBG (3 years), and post-PBG (2 years) periods. Macroinvertebrates and water chemistry were sampled monthly. Nitrate (NO3-) concentrations increased in the fenced and unfenced watersheds compared to the control watersheds (p = 0.015 and p < 0.0001, respectively) and between the fenced and unfenced watersheds (p = 0.001) during the PBG period relative to pre-PBG. Total phosphorus (TP) increased in the fenced and unfenced watersheds after grazing began compared to the control (both p < 0.0001) but did not differ between the fenced and unfenced watersheds (p = 0.187). Relative Chironomidae biomass and abundance increased in the unfenced watersheds in response to grazing (p = 0.008 and p < 0.001, respectively). No differences were observed in relative Chironomidae biomass and abundance, NO3-, and TP from pre-PBG to post-PBG indicating the recovery of these metrics. Results suggest that the negative effects of PBG on prairie streams can be somewhat mitigated by riparian fencing. Additionally, these streams are relatively resilient to PBG and recovery can take place during a rest cycle as brief as two years. Approximately one billion dollars is spent annually on restorations of degraded stream reaches in the United States. However, few projects are monitored upon completion, or monitoring focuses on a single parameter. Other than modifications to physical attributes of streams, the influence of restoration projects on ecosystem processes remains largely unknown. We sampled eleven Midwestern streams that had undergone habitat restorations from 3-15 years prior to sampling. Restoration techniques included in-stream habitat enhancements, bank stabilization, and riparian restoration. We predicted that gross primary production (GPP) would be lower in restored streams due to decreased nutrient inputs, and that respiration would be greater due to increased litter inputs from restored riparian areas. We also hypothesized that the restored streams would have greater invertebrate richness, abundance, and biomass, as well as high densities of intolerant taxa such as Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa) due to higher water quality and better habitat. Restored reaches and unrestored upstream reaches were sampled for physical characteristics, water chemistry, benthic algal biomass, whole-stream metabolism, and macroinvertebrate communities. GPP in restored sites was marginally higher than unrestored sites (t5 = 2.53, p = 0.05), despite no differences in PO4-3, NO3-, or NH4+ concentrations. Three restored sites were autotrophic (P/R > 1), while four unrestored sites were heterotrophic. Total macroinvertebrate biomass was marginally higher in the restored sites compared to unrestored sites (t10 = 1.94; p = 0.08). EPT biomass was also marginally higher in restored sites than unrestored sites (t10 = 1.91; p = 0.09) but no difference was observed in EPT abundance. Results suggest that stream habitat restorations enhance some, but not all ecosystem processes and marginally enhance macroinvertebrate communities.

Thesis, University of Portsmouth, 2018. https://researchportal.port.ac.uk/portal/en/theses/aligning-the-concepts-of-lean-management-and-valuebased-management(9b912c16-c971-41d5-89d2-1c8d398fcab1).html.
Full textAbstract:
This thesis sets out to explore the relationship and compatibility of the appraoches of Lean Management (LM) and Value-based Management (VBM). Previous researchers studying LM and VBM have agreed on the need to harmonise VBM ans the management control system (MCS) with the operational strategy in general, and in particular with regard to the employment of LM. But despite a decade of scholars' calls, the overarching relation between Lm and VBM at the system level has received virtually no attention. In finnaly answering these calls, the study initially familiarises the reader with the concepts and key characteristics of LM and VBM. While reviewing these two approaches, it is found that sueprisingly niether the term 'value' nor 'vlaue driver' is clearly defined. Therefore, a new definition of both terms is presented that captures and harmonises both areas. Subsequently a systematic assessment of LM literature against the six-step normative VBM framework of Ittner and Larcker (2001) is conducted, to determine lean's compatibility to VBM based on existing knowledge. This appraisal finds that although LM is overall highly capable of contributing to the normative VBM demands, there is a key gap, which is the lack of sufficient lean valu driver model. This gap is filled, based on the author's research philosophy of critica; realism, by employing a two-step approach, which contains the creation of an entirely new lean value driver model that froms the foundation for the primary empirical research, by collecting data through interviewing ten top managers with extensive experience in LM. Empirical data provides sufficient evidence regarding the validity of the newly developed conceptual model. Furthermore, highly valuable fresh insights are gained regarding the role and importance of different lean stakeholders, their importance, requirements, contributions, and relationships between them. The resulting final model, which is also the main contribution of this thesis, is found to be superior to previous attempts to apply existing approaches, such as the Balanced Scorecard (BSC), or value trees to the lean environment. Furthermore, the model improves Lm and VBM professional practice as it fosters a shared understanding of the value creation process within a lean system and thereby helps to remove existing barriers. Finally, it supports future fruitful alliances between a company's operational and financial communities, thus enhancing the benefits to the enterprise and its stakeholders.

Full textAbstract:
Wetland mitigation has become a 2.4 billion dollar per year industry in the U.S. and in Virginia it leads to the replacement of 77 ha of palustrine forested wetlands (PFWs) per year with mitigation wetlands, including created forested wetlands (CFWs). Mitigation hinges on the idea that compensation wetlands lead to “no net loss of wetland function” when compared to impacted wetlands. We assessed the functions of provision of habitat and biogeochemical functions associated with production of biomass, the retention and removal of nutrients and the accumulation of soil C over 8 years in seven CFWs of approximately 11 and 20 years and compared them to natural reference wetlands (NRWs). CFW plant communities were similar to NRWs in all measured parameters in the herbaceous and shrub/sapling strata and in all strata combined. However, non-native dominance showed a significant positive linear relationship with CFW age. In the tree strata, 11 year old (yo) CFWs had lower richness than NRWs and both age classes of CFWs had lower FQI than NRWs. NRWs held 10 to 20 times more carbon in woody biomass than CFWs. Tree species composition was significantly different between CFWs and NRWs, however NRW trees were similar to CFW saplings. 11 yo CFWs held lower percentages of C, N and P and had higher Db than NRWs in both the 0-10 and 10-20 cm depth. 20 yo CFWs developed similar levels of %C, %P, bulk density (Db), and nutrient ratios in the surface and displayed rapid increases in %C and %N over 8 years. However, CFWs offered 45% lower soil total soil C storage and 50% lower %N. Furthermore, all CFWs stored lower nutrient levels than NRWs in the 10-20 cm soil depth. We found that FQI correlated positively with total C accumulation rates in woody biomass and soil C, indicating that biogeochemical function and the provision of habitat can be complimentary in CFWs. Finally, 11 and 20 yo CFWs adhered to the regulatory performance standards established for Virginia in terms of stems per ha and wetland indicator status, but all wetlands (including NRWs) failed to achieve <5% non-native species cover.

Full textAbstract:
Background: Most organizations rely on their information system on a daily basis to generate opportunities and advantages. Meanwhile, with the increasing emphasize on corporate social responsibility (CSR), more directors and CEOs are shifting their sights to CSR by developing business models that underline responsible and ethical disciplines for running businesses. However, studies that combine the analysis of IS and CSR are few. Therefore, the potential benefits of utilizing IS from a more intan-gible view, which means CSR in our case, are less likely be discovered. Besides, sen-ior managers have a hard time on shifting perceptions on CSR from being an add-on activity to be integrated in core operations of the organizations. Aim & Purpose: The aim of our research is to investigate the functions that IS has in CSR management from managers' perspectives. As mentioned above, the main reason for con-duction this research is the existing knowledge gap through the subjects being investigated. The overall purpose for this study is to adopt EFQM Excellence Model and Work System Model to contribute to CSR value creation of the organization. Method: The current research approach is qualitative and a case study is applied as re-search strategy. Data collection is carried out by means of documents and interviews. Doc-uments include company annual reports and website information. Semi-structured inter-views are conducted with managers from Lasfosaringar Jokoping and PwC. Conclusions: The functions of IS in the management of CSR can be concluded into four aspects, which are information management, customer relationship management, monitor-ing daily affairs and corporate governance. Information system have changed the way data is being sorted, spread, disseminated and have accelerated the information exchange fre-quency in business operation. Those changes in turn reflect on the performance of cus-tomer, employee and corporate governance of the organization.

Moe, Todd Gregory. "The Many Functions of Commercial Banking: Liquidity Management, Mergers, and Retail Lending." OpenSIUC, 2018. https://opensiuc.lib.siu.edu/dissertations/1616.
Full textAbstract:
The main objective of this dissertation is to provide insight into commercial bank decisionmaking in the United States. To this end, commercial bank behavior is explored in three separate essays. Chapter 1 examines the liquidity adjustment behavior of U.S. commercial banks from 1993-2006. A panel vector autoregressive framework is employed to estimate the dynamic responses of bank loans and liquid assets to a variety of bank funding shocks. Orthogonalized impulse responses reveal that banks respond to disruptions in funding by extending less credit and hoarding liquid assets. This paper also highlights functional differences between small and large banks. Large banks generally have access to capital markets and other external funding sources; small banks do not. As a result, small banks are more sensitive to funding disruptions. Balance sheet liquidity is also vitally important for small banks. Small, liquid banks are able to continue lending in response to disruptions in core deposits while illiquid banks are forced to cut lending. Chapter 2 investigates the effects of bank mergers on deposit growth over the period 1994- 2005. The present study differentiates between mergers initiated by small and large banks. We find empirical evidence of deposit runoff to go along with the anecdotal evidence known to the banking community. Contrary to expectation, mergers initiated by large commercial banks are able maintain their deposit levels while mergers between small banks generally lose deposit funding. Chapter 3 analyzes the impact of the Dodd-Frank Act on key segments of the mortgage market. Error correction models of the residential real estate loan share and the non-jumbo loan share indicate that the Dodd-Frank Act coincided with a dramatic decline in both loan share measures. For example, the Dodd-Frank Act had a negative, long-run effect on the non-jumbo loan share for large commercial banks; reducing the non-jumbo loan share by 15.13%. Moreover, the residential real estate share declined by 8.79%. These findings are consistent with commercial banks re-allocating their loan portfolios in favor of high dollar C&I loans, commercial real estate loans, and jumbo mortgages in response to the increased fixed compliance costs of originating loans under the Dodd-Frank Act.

Considerando a atual subutilização do espectro de rádio frequências para comunicação sem fio, o rádio cognitivo é visto como um conceito chave para permitir uma melhoria da utilização deste recurso de comunicação. A implementação de dispositivos de rádio cognitivo deve basear-se nas quatro principais funções cognitivas: sensoriamento espectral, decisão espectral, compartilhamento espectral e mobilidade espectral. Através dessas funções, um dispositivo de rádio cognitivo é capaz de procurar canais livres para transmitir de forma oportunista em uma rede de rádios cognitivos. No entanto, as redes de rádios cognitivos devem ser gerenciadas, com o objetivo de garantir seu pleno funcionamento, melhorando o desempenho destes dispositivos. Este gerenciamento deve melhorar o conhecimento do administrador sobre o funcionamento da rede. Assim, a configuração, o monitoramento e a visualização das funções cognitivas são fundamentais para o processo de aprendizagem contínua do administrador de rede. Neste trabalho, propõe-se Kitsune, um sistema de gerenciamento com base em um modelo hierárquico que permite gerenciar as informações sobre as funções cognitivas em redes de rádios cognitivos. Kitsune é projetado para gerenciar todas as quatro funções cognitivas, permitindo que o administrador da rede possa configurar os dispositivos de rádio cognitivo, monitorar os resultados de cada função cognitiva e analisar importantes visualizações destes resultados. Além disso, um protótipo de Kitsune foi desenvolvido e avaliado por meio de um cenário experimental baseado na norma IEEE 802.22. O resultado obtido mostra que Kitsune fornece ao administrador um melhor conhecimento sobre a rede, melhorando a taxa de transferência média para cada canal.Considering the current underutilization of radio frequency spectrum for wireless communication, the Cognitive Radio is seen as a key concept to enable the improvement of the radio frequency spectrum utilization. The implementation of cognitive radio devices must be based on the four main cognitive functions: spectrum sensing, spectrum decision, spectrum sharing, and spectrum mobility. Through these functions, a cognitive radio device is able to search for vacant channels to opportunistically transmit in a cognitive radio network. However, cognitive radio networks should be managed, aiming to guaranty the proper operation of the cognitive radio devices, improving the performance of these devices. This management should improve the administrator knowledge about the cognitive radio network operation. Therefore, the configuration, monitoring and visualization of the cognitive functions are fundamental to the continuous knowledge building process of the network administrator. In this paper we propose Kitsune, a management system based on a hierarchical model allowing to manage summarized information about cognitive functions in radio networks. Kitsune is designed to manage all four cognitive functions, enabling the network administrator to configure the cognitive radio devices, monitor the results of each cognitive function, and make important visualizations of these results. Moreover, a Kitsune prototype was developed and evaluated through an experimental IEEE 802.22 scenario. The result obtained show that Kitsune allows the administrator to achieve a better knowledge about the network and improve the average throughput for each channel.

Aujourd'hui, surtout dans le monde numérique, il nous est demandé nos préférences sur toute sorte de choses. La modélisation et gestion de ces préférences ouvrent de nouveaux défis. Ces travaux se concentrent sur les imperfections dans l'information des préférences, telles que l'incertitude, l'imprécision et l'incomplétude. Dans cette thèse, nous passons en revue les méthodes d'état de l'art sur l'agrégation et l'apprentissage des préférences. Fondé sur la théorie des fonctions de croyance, nous proposons une modèle, nommé BFpref, permettant à raisonner les préférences au niveau du coupe à partir d’un degré de croyance. Le modèle BFpref est capable de représenter l'incertitude, l'imprécision ainsi que l'incomplétude par l'ignorance totale dans le cadre des fonctions de croyance. Nous proposons ensuite des stratégies pertinentes pour fusionner de multiple préférences crédibilistes. De plus, une distance sur les préférences imparfaites est introduite afin de tenir compte différemment des quatre types de relations de préférence. Cette distance est nommée Weighted Singleton Distance (WSD). La classification non-supervisée sur les préférences crédibilistes est aussi étudiée en distinguant les préférences complètes et incomplètesToday, especially in the digital world, we are asked about our preferences on many things. Modeling and managing these preferences open up new challenges. This work focuses on imperfections in preference information, such as uncertainty, imprecision and incompleteness. In this thesis, we review state-of-the-art methods on preference aggregation and preference learning. Based on the theory of belief functions, we propose a model of preference information on the pairs of alternatives (or objects) being compared. This model is called Bfpref. BFpref model is capable of expressing uncertainty, imprecision and as incompleteness through total ignorance in the framework of the theory of belief functions. We then propose relevant strategies to fuse multiple belief preferences. In addition, a distance on imperfect preferences is introduced to take into account the four types of preference relationships differently. This distance is called Weighted Singleton Distance (WSD). The unsupervised classification on imperfect preferences with BFpref model is also studied by distinguishing between complete and incomplete preferences

Full textAbstract:
The purposed of this quantitative study was to identify whether leadership skill requirements to perform one’s job effectively varies by job function. This research focuses on leadership skill rather than other leadership constructs such as leadership traits because leadership skills can be developed and improved upon. Past research in this area has identified that leadership skill requirements vary by level within an organization (executive, middle management, lower management) but nothing exists examining by job function (Mumford, Campion, & Morgeson, 2007). In this research, the job functions examined were sales, human resources, and finance, and 146 interviews were completed. The results showed that certain softer leadership skills (listening and critical thinking) were more important leadership skills across all 3 functions. The findings also suggest that leadership skill requirements were not the same for the 3 job functions. Sales professionals required more interpersonal skill than their finance counterparts.

Within organizations, "core" functions directly contribute to organizational production, whereas "peripheral" functions offer support by maintaining key infrastructure. Commonly viewed as indirect contributors or even adversaries to value, peripheral functions operate from positions of low authority and status, struggling to achieve their mandates and to build relationships that enable them to deliver optimal value to organizations. I argue that the peripheral status of these functions stems from a biased valuation process, in which compliance work, often negatively valued, is highly visible, whereas work inherently valuable to organizational pursuits is less visible. Building on an ethnographic study of peripheral Environmental Health and Safety (EHS) professionals in a university setting, this paper shows how these workers, recognizing that existing narratives undervalued their contributions, enacted their own narratives to address the visibility issues inherent in the valuation process. In doing so, these workers achieved higher status and more functional relationships with core workers. Specifically, EHS professionals first minimized the visibility of disruptions due to compliance, thereby building relationships of client service. Second, EHS professionals made visible inherent connections between their work and core organizational goals, thereby breaking down barriers between peripheral and core work, and building partnerships with core workers.

La comparaison avec l'historique du domaine se fait généralement manuellement pas le biais de la littérature, qui permet de définir des régions d'intérêt dans le cerveau. Les méta-analyses permettent de définir des méthodes plus formelles et automatisables pour analyser la littérature. Cette thèse examine trois manières d'accumuler et d'organiser les connaissances sur le fonctionnement du cerveau en utilisant des cartes d'activation cérébrales d'un grand nombre d'études. Premièrement, nous présentons une approche qui utilise conjointement deux expériences d'IRMf similaires pour mieux conditionner une analyse statistique. Nous montrons que cette méthode est une alternative intéressante par rapport aux analyses qui utilisent des régions d'intérêts, mais demande cependant un travail manuel dans la sélection des études qui l'empêche de monter à l'échelle. A cause de la difficulté à sélectionner automatiquement les études, notre deuxième contribution se focalise sur l'analyse d'une unique étude présentant un grand nombre de conditions expérimentales. Cette méthode estime des réseaux fonctionnels (ensemble de régions cérébrales) et les associe à des profils fonctionnels (ensemble pondéré de descripteurs cognitifs). Les limitations de cette approche viennent du fait que nous n'utilisons qu'une seule étude, et qu'elle se base sur un modèle non supervisé qui est par conséquent plus difficile à valider. Ce travail nous a cependant apporté la notion de labels cognitifs, qui est centrale pour notre dernière contribution. Cette dernière contribution présente une méthode qui a pour objectif d'apprendre des atlas fonctionnels en combinant plusieurs jeux de données. [Henson2006] montre qu'une inférence directe, c.a.d. la probabilité d'une activation étant donné un processus cognitif, n'est souvent pas suffisante pour conclure sur l'engagement de régions cérébrales pour le processus cognitif en question. Réciproquement, [Poldrack 2006] présente l'inférence inverse qui est la probabilité qu'un processus cognitif soit impliqué étant donné qu'une région cérébrale est activée, et décrit le risque de raisonnements fallacieux qui peuvent en découler. Pour éviter ces problèmes, il ne faut utiliser l'inférence inverse que dans un contexte où l'on suffisamment bien échantillonné l'espace cognitif pour pouvoir faire une inférence pertinente. Nous présentons une méthode qui utilise un « meta-design » pour décrire des tâches cognitives avec un vocabulaire commun, et qui combine les inférences directe et inverse pour mettre en évidence des réseaux fonctionnels qui sont cohérents à travers les études. Nous utilisons un modèle prédictif pour l'inférence inverse, et effectuons les prédictions sur de nouvelles études pour s'assurer que la méthode n'apprend pas certaines idiosyncrasies des données d'entrées. Cette dernière contribution nous a permis d'apprendre des réseaux fonctionnels, et de les associer avec des concepts cognitifs. Nous avons exploré différentes approches pour analyser conjointement des études d'IRMf. L'une des difficultés principales était de trouver un cadre commun qui permette d'analyser ensemble ces études malgré leur diversité. Ce cadre s'est instancié sous la forme d'un vocabulaire commun pour décrire les tâches d'IRMf. et a permis d'établir un modèle statistique du cerveau à grande échelle et d'accumuler des connaissances à travers des études d'IRM fonctionnelleHow can we accumulate knowledge on brain functions? How can we leverage years of research in functional MRI to analyse finer-grained psychological constructs, and build a comprehensive model of the brain? Researchers usually rely on single studies to delineate brain regions recruited by mental processes. They relate their findings to previous works in an informal way by defining regions of interest from the literature. Meta-analysis approaches provide a more principled way to build upon the literature. This thesis investigates three ways to assemble knowledge using activation maps from a large amount of studies. First, we present an approach that uses jointly two similar fMRI experiments, to better condition an analysis from a statistical standpoint. We show that it is a valuable data-driven alternative to traditional regions of interest analyses, but fails to provide a systematic way to relate studies, and thus does not permit to integrate knowledge on a large scale. Because of the difficulty to associate multiple studies, we resort to using a single dataset sampling a large number of stimuli for our second contribution. This method estimates functional networks associated with functional profiles, where the functional networks are interacting brain regions and the functional profiles are a weighted set of cognitive descriptors. This work successfully yields known brain networks and automatically associates meaningful descriptions. Its limitations lie in the unsupervised nature of this method, which is more difficult to validate, and the use of a single dataset. It however brings the notion of cognitive labels, which is central to our last contribution. Our last contribution presents a method that learns functional atlases by combining several datasets. [Henson 2006] shows that forward inference, i.e. the probability of an activation given a cognitive process, is often not sufficient to conclude on the engagement of brain regions for a cognitive process. Conversely, [Poldrack 2006] describes reverse inference as the probability of a cognitive process given an activation, but warns of a logical fallacy in concluding on such inference from evoked activity. Avoiding this issue requires to perform reverse inference with a large coverage of the cognitive space. We present a framework that uses a "meta-design" to describe many different tasks with a common vocabulary, and use forward and reverse inference in conjunction to outline functional networks that are consistently represented across the studies. We use a predictive model for reverse inference, and perform prediction on unseen studies to guarantee that we do not learn studies' idiosyncrasies. This final contribution permits to learn functional atlases, i.e. functional networks associated with a cognitive concept. We explored different possibilities to jointly analyse multiple fMRI experiments. We have found that one of the main challenges is to be able to relate the experiments with one another. As a solution, we propose a common vocabulary to describe the tasks. [Henson 2006] advocates the use of forward and reverse inference in conjunction to associate cognitive functions to brain regions, which is only possible in the context of a large scale analysis to overcome the limitations of reverse inference. This framing of the problem therefore makes it possible to establish a large statistical model of the brain, and accumulate knowledge across functional neuroimaging studies

Full textAbstract:
This thesis studies the structure of project management offices (PMO), the functions they usually contain and the ways that they can be organized. The study’s objective is to find out what kind of a project management office structure best supports the operations of an IT outsourcing and consulting services providing multinational company’s Nordic project delivery. The methodology chosen for this study is qualitative. The research tools are literature reviews and interviews conducted in the target organization. Based on the results of the reviews and interviews, an answer for the research questions has been composed, as well as a recommendation on the structure and tasks of the PMO in the target organization. The basis of this study is previous literature on the way of organizing PMOs, different PMO maturity models and on the functions that PMOs contain. The literature review has been applied to the composition of an interview questionnaire which was used for interviewing employees of the target organization. The most important result of this study, the recommendation on the structure and organization of the PMO, is therefore based on both earlier research as well as on new empirical research conducted only for the purposes of this study. The most important result of this study is a project management office model, which can be applied to IT consulting services offering project and services companies, if the internal processes of the companies are at a sufficiently formal level. The PMO should support project delivery by allocating project resources, by acting as a coordinator between parallel projects, by capturing and recording lessons learned from closed projects for later use in the organization and by developing the project management methodologies within its host organization. New research subjects for further study in the field of project management research have been identified as a result of the study. The results of the study will be used in the target organization for the re-organization of the PMO, where applicable. The results can be generalized for companies of the same type either in IT or other project business and utilized for internal developmentTyössä tutkitaan projektinhallintatoimistojen (project management office, PMO) rakennetta, niiden yleisesti suorittamia tehtäviä sekä organisointitapoja. Tutkimuksessa pyritään selvittämään, millainen projektinhallintatoimiston malli soveltuu parhaiten tukemaan IT-ulkoistusta sekä -konsultointia tarjoavan monikansallisen yrityksen Pohjoismaiden projektitoimitusta. Tutkimuksessa käytetty tutkimusmenetelmä on laadullinen. Tutkimuksen välineinä on hyödynnetty kirjallisuuskatsausta sekä haastattelututkimusta kohdeyrityksessä. Saatujen tulosten perusteella on laadittu vastaus asetettuihin tutkimuskysymyksiin sekä suositus projektinhallintatoimiston organisointitavasta sekä projektinhallintatoimiston tehtävistä kohdeyrityksessä. Työssä on tutkittu aiempaa tutkimuskirjallisuutta projektinhallintatoimistojen organisointitapojen, maturiteettimallien sekä niiden suorittamien tehtävien osalta ja sovellettu kirjallisuuskatsauksen tuloksia empiirisen osion perustana olleen haastattelujen haastattelurungon valmisteluun. Työn tärkein lopputulos, esitetty suositus projektinhallintatoimiston organisointitavasta, perustuu näin ollen sekä aiempaan tutkimukseen että tätä työtä varten suoritettuun empiiriseen tutkimukseen. Työn tärkein tulos on yleinen projektinhallintatoimiston malli, joka soveltuu IT-konsultointipalveluja tarjoavaan projekti- ja palveluyritykseen jonka sisäiset prosessit ovat riittävän formalisoituja. Projektinhallintatoimiston tulisi tukea projektitoimitusta allokoimalla projektiresursseja, toimimalla koordinaattorina samaan aikaan suoritetuille projekteille, taltioimalla projekteista opitut asiat organisaation myöhempää käyttöä varten sekä vastaamalla projektinhallintametodologian kehityksestä. Työssä on myös tunnistettu uusia tutkimusaiheita projektinhallinnan tieteenalalla, joiden jatkotutkimus olisi suotavaa. Tutkimuksen tuloksia käytetään kohdeorganisaation projektinhallintatoimiston organisointiin soveltuvilta osin. Tulokset ovat yleistettävissä vastaaviin IT- tai muiden alojen projektiliiketoimintaa suorittaviin yrityksiin, ja niitä voidaan käyttää tukemaan yritysten sisäisten toimintamallien kehitystä

Full textAbstract:
The purpose of management strategies is to support a better allocation of water to the wetlands resources so that they can receive enough water, in quality, quantity and timeliness suitable to continue to provide their goods and services. The following strategic guidelines are explained below:
Sustainability as a goal. Adequate water has to be provided to wetlands to sustain the functioning of these ecosystems, respecting their natural dynamics for the benefit of future generations. Where water requirements are not known, or where the impact of reducing water allocation to wetlands is unclear, the precautionary approachshould be applied. The wetland ecosystem is the resource base from which water is derived. It should be managed to protect the resource base in order to provide goods and services in a sustainable manner. This requires sufficient water allocation to maintain wetland ecosystem structure and function. This is directly compatible with the “wise use” concept embodied in the Ramsar Convention, which has been defined by the Conference of the Parties as “the sustainable utilisation of wetlands for the benefit of mankind in a way compatible with the maintenance of the natural properties of the ecosystem”.

Thesis (MBA (Business Management))--University of Stellenbosch, 2001.ENGLISH ABSTRACT: The project accounting function is not adequately defined in project management and accounting textbooks. The objectives of this study were to identify the capabilities and potential involvement of the management and financial accountant in project management and to compare these with the responsibilities of the project accountant. A literature study was done. Shortcomings of conventional accounting techniques when applied in proj ect management were identified. This study concluded that the management and financial accountant, combined, is not equivalent to the project accountant. There are certain functions for which the management and financial accountant are qualified, which will not easily be fulfilled by the project accountant. Similarly neither the management nor the financial accountant fully defines the responsibilities of the project accountant and his or her responsibilities would normally include responsibilities other than conventional management and financial accounting. It was not found possible to draw up a list of generic responsibilities for the project accountant. The findings of this study give rise to the possible need for training in dedicated project accounting skills and the development of a professional project accounting qualification. The need for further empirical research was identified.
AFRIKAANSE OPSOMMING: Die projek rekenmeestersfunksie word nie voldoende beskryf in projekbestuur en rekeningkunde handboeke nie. Die doelwitte van hierdie studie was om die vaardighede en die potensiele betrokkenheid van die bestuurs- en die finansiele rekenmeester in projekbestuur te identifiseer en te vergelyk met die verantwoordelikhede van die projekrekenmeester. 'n Literatuurstudie is gedoen. Tekortkominge in konvensionele rekeningkundige metodes, wanneer dit in projekbestuur toegepas word, is geidentifiseer. Hierdie studie het tot die slotsom gekom, dat die bestuursrekenmeester en die finansiele rekenmeester, gekombineer, nie gelyk is aan die projekrekenmeester nie. Daar bestaan sekere funksies waarvoor die bestuurs- en die finansiele rekenmeester voldoende gekwalifiseer is, wat nie normaalweg deur die projekrekenmeester verrig sal word nie. Netso definieer die bestuursrekenmeester en die finansiele rekenmeester gesamentlik nie die verantwoordelikhede van die projekrekenmeester ten volle nie. Die verantwoordelikhede van die projekrekenmeester sal normaalweg funksies buite konvensionele bestuurs- en finansiele rekeningkunde insluit. Dit het problematies geblyk te wees om 'n generiese lys van verantwoordelikhede vir die projekrekenmeester op te stel. Die bevindinge van hierdie studie lei tot die moontlike behoefte vir opleiding in vaardighede vir projekrekenmeesters en die ontwikkeling van 'n professionele projekrekenmeester kwalifikasie. 'n Behoefte aan verdere empiriese navorsing is gerdentifiseer.

Full textAbstract:
This study explored human resource management (HRM) functions of 200 work organizations operating in Turkey using a questionnaire. The participating organizations were the members of either the Personnel Managers Association or the Quality Association in Turkey. Job analysis and design, recruitment and selection, orientation and employee training, performance appraisal, career planning and development, human resource planning, compensation management and incentives, managing employee health and safety were among the fields that were examined. In addition to the prevalent HRM functions, the profile of Human Resource Departments of the organizations (i.e., title, size, number of hierarchical levels, etc.), the characteristics of HRM managers (education, age, gender, experience, etc.) were also examined. For example, it was found that the departments operating in field of HRM were named Human Resource Department in 59.5% of the organizations in the sample. Moreover, the results indicated that the main HRM areas practiced by the private sector organizations operating in Turkey were personnel selection, employee recruitment, training and development, compensation management, and employee orientation. Nevertheless, the other essential functions of HRM, such as job analysis, human resource planning and career planning, and development were not practiced as frequently. Whether those functions were frequently practiced or not, each of them was further analysed in terms their specific applications. Another aim of the present study was to compare the practices of HRM in Turkey with its applications in the world. For instance, the results demonstrated that recruiting via internet was practiced frequently in the surveyed organizations and in the US companies. The present study also revealed that personnel selection methods, such as interviews, were popular among surveyed organizations and organizations in Eastern European countries, England, and the US.

Full textAbstract:
Land use practices over the last 200 years have dramatically altered the distribution and amount of riparian vegetation throughout many catchments in Australia. This has lead to a number of negative impacts including a decrease in water quality, an increase in sediment transport and a decrease in the quality of terrestrial and aquatic habitats. The task of restoring the functions of riparian zones is an enormous one and requires spatial and temporal prioritisation. An analysis of the existing and historical functions of riparian zones and their spatial distribution is a major aid to this process and will enable efficient use of remediation resources. The approach developed in this thesis combines remote sensing, field measurement and terrain analysis to describe the distribution of five riparian zone functions: sediment trapping, bank stabilization, denitrification, stream shading and large woody debris production throughout a large semi-arid catchment in central Queensland.

Full textAbstract:
Two applications of a binary tree data type based on a simple pairing function (a bijection between natural numbers and pairs of natural numbers) are explored. First, the tree is used to encode natural numbers, and algorithms that perform basic arithmetic computations are presented along with formal proofs of their correctness. Second, using this "canonical" representation as a base type, algorithms for encoding and decoding additional isomorphic data types of other mathematical constructs (sets, sequences, etc.) are also developed. An experimental application to a memory management system is constructed and explored using these isomorphic types. A practical analysis of this system's runtime complexity and space savings are provided, along with a proof of concept framework for both applications of the binary tree type, in the Java programming language.

Full textAbstract:
This dissertation consist of three contributions to financial and insurance mathematics. The first part considers numerical methods for dynamic portfolio optimisation in the expected utility model. The aim is to compare the risk-neutral computational approach (RNCA) also known as the martingale approach to stochastic dynamic programming (SDP) in a discrete-time setting. The main idea of the RNCA is to use the completeness and the arbitrage free properties of the market to compute the optimal consumption rules and then determine the trading strategy that finance this optimal consumption. In contrast, SDP solves for the optimal consumption and investment rules simultaneously using backward recursion and the principle of optimality. The setting that we consider is a discrete time and state space lattice. We provide some new theoretical results relating to the Hyperbolic Absolute Risk Aversion class of utility functions as well as propose a straightforward implementation of RNCA in binomial and trinomial lattices. Moreover, instead of discretizing the Hamilton-Jacobi-Bellman equation with possibly more than one state variable, we use symbolic algorithms to implement stochastic dynamic programming. This new approach provides a simpler numerical procedure for computing optimal consumption-investment policies. A comparison of the RNCA with SDP demonstrates the superiority of the RNCA in terms of computation. The second part considers the pricing of contingent claims using an approach developed and applied in applied in insurance. This approach utilize probability distortion functions as the dual of the utility functions used in financial theory. The main idea of the dual theory is to distort the subjective probabilities rather than outcomes to express the investor????????s risk aversion. In the first part, the RNCA for asset allocation uses the same principle as risk-neutral valuation for derivative pricing. The idea of the second part of this research is to show that the risk-neutral valuation can be recovered from the probability distortion function approach, thereby establishing consistency between the insurance and the financial approaches. We prove that pricing contingent claims under the real world probability measure using an appropriate distortion operator produces arbitrage-free prices when the underlying asset prices are log-normal. We investigate cases when the insurance-based approach fails to produce arbitrage-free prices and determine the appropriate distortion operator under more general assumptions than those used in Black-Scholes option pricing. In the third part we introduce dynamic portfolio optimisation with risk measures based on probability distortion function and provide a formal treatment of this class of risk measures. We employ the RNCA to study the consumption-investment problem in discrete time with preferences consistent with Yaari????????s dual (non-expected utility) theory of choice. As an application, we first consider risk measures based on the Proportional Hazard Transform that treats the upside and downside of the risk differently and secondly a risk measure based on the standard Normal cumulative distribution function. When the objective is to maximise a dual utility of wealth, and the underlying security returns are normal, the efficient frontier is found to be the same as in the mean-variance portfolio problem for an equivalent risk tolerance. When the objective is to maximise a dual utility of consumption, then ????????plunging???????????? behaviour occurs ( investing everything is the risky asset). Other properties of the optimal consumption-investment policies in the dual theory are also investigated and discussed.

Full textAbstract:
This thesis spans the cusp of the 20th and 21st centuries when enterprises were making the transition from the use of paper based to digitally based tools and methodologies to support the design and manufacture of new products. This transition occurred during a period when the globalisation of these activities was driven by the introduction of new, so-called "Information Technologies". During this period, software vendors introduced products to cater for the new demand for the management of increasing amounts of digital data created by computer-based tools and methods. Product Data Management systems are one such example and are the focus of this thesis. Larger enterprises have embraced these technologies and the benefits from such systems are now apparent. However, the uptake of these technologies by Small and Medium sized Enterprises (SMEs) is low by comparison.
The need for data management products was driven by larger enterprises and the underlying research behind these tools and methods followed, rather than led, their introduction. As a consequence, tools and methods were proposed and implemented without due regard to the underlying concepts, nor was consideration given to how such tools and methodologies would be utilised by enterprises that varied in a multitude of ways. This area of research is important because SMEs comprise the majority of New Zealand and global enterprises. There is a need to develop suitable computer-based tools and methods to manage data to ensure SMEs can compete in an environment that is increasingly based on the creation and communication of digital data.
This thesis seeks to contribute to the field of product data management in two ways;
• Firstly, a fundamental conceptual model describing data classes and interactions by enterprises performing product development is developed.
• Secondly, the developed model is used to underpin the design, development and implementation of a novel method for managing data created and used by SMEs.
Suggestions for further development of the model and method will be made at the conclusion of the thesis.

Full textAbstract:
The application of crop residues is one of the most common agricultural practices used to maintain soil ecosystems and crop productivity. This thesis focuses on the oil palm (Elaeis guineensis) agroecosystem, an important tropical crop that has expanded rapidly over the past four decades. Both land conversion and business-as-usual practices within the plantations have contributed to soil degradation. The application of oil palm residues, such as empty fruit bunches (EFB) and oil palm fronds, are thought to have positive effects on the soil ecosystem; yet there is currently a deficit of knowledge on their effectiveness. This thesis aims to examine the effects of oil palm residue application on soil physicochemical properties, soil biota, and ecosystem functions. It reports the results of extensive field trials, sample collection, and statistical analysis of crop residue applications in oil palm plantations in Central Sumatra, Indonesia. Four key results emerged from the thesis. First, in this study site land conversion from secondary forest to oil palm does not affect litter decomposition rate, but positively influences soil fauna activity. Second, there is greater soil fauna activity following EFB application than oil palm fronds or chemical fertilizers, and the fauna activity is highly associated with changes in soil chemical properties and soil moisture conditions. Third, EFB application enhances soil ecosystem functions, through the direct provision of organic matter, and by influencing soil biota. Finally, over 15 years of application, EFB appears to be effective in maintaining or increasing annual crop yield in comparison to chemical fertiliser treatment. Temporal changes in crop yield under EFB application appear to be associated with climatic conditions and soil organic carbon. Overall, these findings improve our understanding of the potential of oil palm residue applications to increase soil quality, soil biota, and ecosystem functions. They also provide useful information for a wider audience of soil ecologists, agricultural managers, and policy makers to improve sustainable management of the oil palm ecosystem.

Conjunctive management of surface and ground -water resources on state and

evolved, in part, in response to growing populations with ever -increasing, and often
conflicting, water demands. In addition, a more sophisticated technical understanding
of the physical link between groundwater and surface waters has led water managers to
reconsider historical strategies for solving water supply problems. In light of growing
demand and improved technology, some western states have begun the transition from
crisis- oriented water management to one of long -term planning for population growth
and environmental protection. This planning process requires that the constituents of a
region define their water use goals and objectives so that various approaches to
conjunctive management may be evaluated for their suitability to that particular
physical and socio- political environment.

A Virtualização de Funções de Rede (Network Functions Virtualization - NFV) está mudando o paradigma das redes de telecomunicações. Esta nova tecnologia permite diversas oportunidades de inovações e possibilita o desenvolvimento de novos modelos de negócio. Em relação às redes NFV, os provedores de serviços têm a oportunidade de criar modelos de negócio que permitam aos clientes contratarem Funções de Rede Virtualizadas (Virtual Network Functions - VNFs) que proveem diferentes serviços de rede (e.g., Firewall, NAT e transcoders). Porém, nestes modelos, a quantidade de informações a serem gerenciadas cresce rapidamente. Baseado nisso, os operadores de rede devem ser capazes de entender e manipular uma grande quantidade de informação para gerenciar, de forma efetiva, as redes NFV. Para enfrentar esse problema, introduzimos uma plataforma de visualização denominada VISION, a qual tem como principal objetivo ajudar os operadores de rede na identificação da causa raiz de problemas em NFV. Para isso, propusemos: (i) uma abordagem para coleta e organização de dados do ambiente NFV gerenciado; (ii) cinco diferentes visualizações que auxiliam nas tarefas de gerenciamento de NFV como, por exemplo, no processo de identificação de problemas em VNFs e no planejamento de negócios e (iii) um modelo baseado em templates que suporta o desenvolvimento e o reuso de visualizações. Para fins de avaliação desta dissertação, foi desenvolvido um protótipo da plataforma VISION e de todas as visualizações propostas. Após, conduzimos um conjunto de casos de estudo para prover evidências sobre a viabilidade e utilidade de nossas visualizações. Os diferentes casos analisados, abordam por exemplo, a identificação de problemas na alocação de VNFs que estão impactando no desempenho do serviço oferecido e também na investigação de prioridades de investimento para suprir as demandas dos clientes da rede. Por fim, apresentamos uma avaliação de usabilidade realizada juntamente a especialistas em redes de computadores para avaliar os recursos e benefícios da plataforma VISION. Os resultados obtidos demonstram que nossas visualizações possibilitam ao operador de rede um rápido e fácil acesso às informações importantes para o gerenciamento de redes NFV, assim facilitando a obtenção de insights para a identificação de problemas complexos no contexto de redes NFV. Além disso, os resultados demonstram uma avaliação positiva por especialistas sobre os aspectos gerais de usabilidade do protótipo desenvolvido.Network Functions Virtualization (NFV) is driving a paradigm shift in telecommunications networks and computer networks, by fostering new business models and creating innovation opportunities. In NFV-enabled networks, service providers have the opportunity to build a business model where tenants can purchase Virtual Network Functions (VNFs) that provide distinct network services and functions (e.g., Firewall, NAT, and transcoders). However, the amount of managed data grows in a fast pace. The network operator must understand and manipulate many data to effectively manage the network. To tackle this problem, we introduce VISION, a platform based on visualizations techniques to help network operators to determine the cause of not obvious problems. For this, we provide: (i) an approach to collect and organize data from the NFV environments; (ii) five distinct visualizations that can aid in NFV management tasks, such as in the process of identifying VNFs problems and planning of NFV-enabled businesses; and (iii) a template model that supports new visualization applications. To evaluate our work, we implemented a prototype of VISION platform and each of the proposed visualizations. We then conducted distinct case studies to provide evidence of the feasibility of our visualizations. These case studies cover different scenarios, such as the identification of misplacement of VNFs that are generating bottlenecks in a forwarding graph and the investigation of investment priorities to supply tenants demands. Finally, we present a usability evaluation with network operators to indicate the benefits of the VISION platform. The results obtained show that our visualizations allow the operator to access relevant information and have insights to identify not obvious problems in the context of NFV-enabled networks. In addition, we received positive feedback about general usability aspects related to our prototype.

Thesis (PhD)--Stellenbosch University, 2002.ENGLISH ABSTRACT: Correlation mechanisms describing systematic variations and common sensitivities are critical contributors to uncertainty in quantitative functions modelling project performance in terms of probabilistic or basic variables. Current reliability methods transform dependent vectors to an equivalent set of independent standard normal variates. A simple method is developed for dealing with correlation in the original variable space. An algebraic description of the direction cosine (or alpha) for performance functions under conditions of dependence is formally derived and numerically validated. The resultant General First Order Second Moment (GFOSM) method for correlated basic variables is shown to be equivalent to the orthogonal transformation method. Geometric and physical interpretations of the general direction cosine are developed, with alpha found to be equivalent to the correlation between a basic variable and performance function. Corresponding inequalities and normalizing conditions are also developed for alpha. Expressions for a number of applications utilising the general dependent form for the direction cosine are derived and demonstrated. The current definition of the direction cosine as an importance factor is validated for dependent conditions, and conditions established under which this descriptor is no longer adequate. Expressions are derived to measure the significance of a variable in terms of stochastic importance and function sensitivity, to establish reliability index sensitivity to the omission of non-critical items, quantifying variable elasticity and an elasticity index. The general FOSM method for correlated basic variables is applied to system analysis to generate modal correlation coefficients between failure modes. The general direction cosine is stable for multivariate linear functions and functions of limited curvature across a range of reliabilities and correlation levels. This characteristic further simplifies the process by providing for deterministic reliability modelling of performance functions containing dependent variables, avoiding the solution of the more complex joint density function. The extension of the current theory and the treatment of performance functions in the original vector space develop invaluable insight into the correlation mechanisms driving risk and reliability. This will assist project managers to better understand areas that can affect project performance, to focus management attention, develop mitigation strategies and to allocate resources for the optimal management of project risk.
AFRIKAANSE OPSOMMING: Korrelasie meganismes wat sistematiese afwykings en gemeenskaplike sensitiwiteite veroorsaak, is kritieke bydraers tot onsekerheid in kwantitatiewe funksies wat projek prestasie modelleer m terme van probabilistiese of basiese veranderlikes. Huidige betroubaarheidsmetodes transformeer afhanklike vektore tot 'n ekwivalente stel van standaard normaalonafhanklike veranderlikes. '0 Eenvoudige metode is ontwikkelom die effekte van korrelasie in die oorspronklike vektorspasie te hanteer. 'n Algebraise beskrywing van die rigtingseosines (genoem alfa) vir prestasiefunksies onder omstandighede van afhanklikheid is formeel afgelei en numeries gevalideer. Dit is bewys dat die resulterende Algemene Eerste Orde Tweede Moment metode vir gekorreleerde basiese veranderlikes ekwivalent is aan die tradisionele Ortogonale Transformasie metode. Geometriese en fisiese interpretasies vir die algemene rigtingscosinus is ontwikkel, met bewys dat alfa ekwivalent is aan die korrelasie tussen 'n basiese veranderlike en die prestasiefunksie. Ooreenstemmende ongelykhede en normaliserings-kondisies is ook vir alfa ontwikkel. Uitdrukkings vir 'n aantal toepassings wat gebruik maak van die algemene afhanklike vorm van die rigtingscosinus is afgelei en gedemonstreer. Die huidige definisie van die rigtingscosinus as 'n belangrikheidsfaktor is gevalideer vir kondisies van afhanklikheid en omstandighede is uitgewys wanneer dit onvoldoende is. Uitdrukkings is afgelei om stochastiese belangrikheid te meet asook funksie sensitiwiteit, die sensitiwiteit van die betroubaarheidsindeks tot die weglating van nie kritiese veranderlikes, sowel as die kwantifisering van elastisiteit en die elastisiteitsindeks. Die Algemene Eerste Orde Tweede Moment metode vir gekorreleerde' veranderlikes is toegepas op sisteem analise om die korrelasie tussen falingsmodes te genereer. Die algemene rigtingscosinus is stabiel vir liniêre funksies en funksies met 'n beperkte kromming oor 'n reeks betroubaarheidswaardes en korrelasie vlakke. Hierdie kenmerk vereenvoudig die metode verder deur voorsiening te maak vir deterministiese betroubaarheidsmodellering van prestasie funksies met afhanklike veranderlikes, deur die oplossing van die meer komplekse gesamentlike-digtheidsfunksies te vermy. Die uitbreiding van die huidige teorie en die hantering van prestasie funksies in die oorspronklike vektor spasie ontwikkel waardevolle insig in die korrelasie meganismes wat risiko en betroubaarheid oorheers. Hierdie insig sal projekbestuurders in staat stelom kritieke gebiede wat projek prestasie kan affekteer beter te verstaan, om hulle aandag daarop te fokus, om teenmaatreël-strategieë te ontwikkel en hulpbronne toe te ken vir die optimale bestuur van projek risiko.

I estimate the out-of-sample performance of the equal weight, minimum variance and mean-variance model portfolios in different settings. In each setting, I vary the loss function used when estimating returns and covariances, length of the estimation window, and number of factors used in our estimation model. I find that when measuring performance by Sharpe ratio, choice of loss function strongly influences whether the mean-variance model portfolio outperforms the equal weight or minimum variance portfolio, and that the optimal loss function depends on the length of the estimation window and the dimension of the return model. It appears that we don't gain much by using more factors. The 3-factor model does a pretty good job based on Sharpe ratio, and the results are consistently the best for MVO(10). With more factors, it seems clear that we need longer estimation windows, but even then we do not gain anything in terms of Sharpe Ratio. However, when measuring performance by the certainty-equivalent return, I find that the mean-variance model portfolio does not outperform the minimum variance portfolio or the equal weight portfolio in any setting. This suggests that choosing a loss function carefully is imperative to managing estimation errors and that an investor's utility preferences and attitude towards risk should be taken into account when choosing a measure of performance.
