The firm is faced with a decision concerning the nature of intra-organizational exchange relationships with internal human resources and the nature or inter-organizational exchange relationships with market firms. In both situations, the firm can develop an exchange that ranges from a discrete exchange to a relational exchange. Transaction Cost Economics (TCE) and the Resource Dependency View (RDV) represent alternative efficiency-based explanations fo the nature of the exchange relationship. The aim of the paper is to test these two theories in respect of air conditioning maintenance in retail centres. Multiple sources of information are genereated from case studies of Australian retail centres to test these theories in respoect of internalized operations management (concerning strategic aspects of air conditioning maintenance) and externalized planned routine air conditioning maintenance. The analysis of the data centres on pattern matching. It is concluded that the data supports TCE - on the basis of a development in TCE's contractual schema. Further research is suggested towards taking a pluralistic stance and developing a combined efficiency and power hypothesis - upon which Williamson has speculated. For practice, the conclusions also offer a timely cautionary note concerning the adoption of one approach in all exchange relationships.

The degree of reliance of newborn sharks on energy reserves from maternal resource allocation and the timescales over which these animals develop foraging skills are critical factors towards understanding the ecological role of top predators in marine ecosystems. We used muscle tissue stable carbon isotopic composition and fatty acid analysis of bull sharks Carcharhinus leucas to investigate early-life feeding ecology in conjunction with maternal resource dependency. Values of δ13C of some young-of-the-year sharks were highly enriched, reflecting inputs from the marine-based diet and foraging locations of their mothers. This group of sharks also contained high levels of the 20:3ω9 fatty acid, which accumulates during periods of essential fatty acid deficiency, suggesting inadequate or undeveloped foraging skills and possible reliance on maternal provisioning. A loss of maternal signal in δ13C values occurred at a length of approximately 100 cm, with muscle tissue δ13C values reflecting a transition from more freshwater/estuarine-based diets to marine-based diets with increasing length. Similarly, fatty acids from sharks >100 cm indicated no signs of essential fatty acid deficiency, implying adequate foraging. By combining stable carbon isotopes and fatty acids, our results provided important constraints on the timing of the loss of maternal isotopic signal and the development of foraging skills in relation to shark size and imply that molecular markers such as fatty acids are useful for the determination of maternal resource dependency.

In recent times, the improved levels of accuracy obtained by Automatic Speech Recognition (ASR) technology has made it viable for use in a number of commercial products. Unfortunately, these types of applications are limited to only a few of the world’s languages, primarily because ASR development is reliant on the availability of large amounts of language specific resources. This motivates the need for techniques which reduce this language-specific, resource dependency. Ideally, these approaches should generalise across languages, thereby providing scope for rapid creation of ASR capabilities for resource poor languages. Cross Lingual ASR emerges as a means for addressing this need. Underpinning this approach is the observation that sound production is largely influenced by the physiological construction of the vocal tract, and accordingly, is human, and not language specific. As a result, a common inventory of sounds exists across languages; a property which is exploitable, as sounds from a resource poor, target language can be recognised using models trained on resource rich, source languages. One of the initial impediments to the commercial uptake of ASR technology was its fragility in more challenging environments, such as conversational telephone speech. Subsequent improvements in these environments has gained consumer confidence. Pragmatically, if cross lingual techniques are to considered a viable alternative when resources are limited, they need to perform under the same types of conditions. Accordingly, this thesis evaluates cross lingual techniques using two speech environments; clean read speech and conversational telephone speech. Languages used in evaluations are German, Mandarin, Japanese and Spanish. Results highlight that previously proposed approaches provide respectable results for simpler environments such as read speech, but degrade significantly when in the more taxing conversational environment. Two separate approaches for addressing this degradation are proposed. The first is based on deriving better target language lexical representation, in terms of the source language model set. The second, and ultimately more successful approach, focuses on improving the classification accuracy of context-dependent (CD) models, by catering for the adverse influence of languages specific phonotactic properties. Whilst the primary research goal in this thesis is directed towards improving cross lingual techniques, the catalyst for investigating its use was based on expressed interest from several organisations for an Indonesian ASR capability. In Indonesia alone, there are over 200 million speakers of some Malay variant, provides further impetus and commercial justification for speech related research on this language. Unfortunately, at the beginning of the candidature, limited research had been conducted on the Indonesian language in the field of speech science, and virtually no resources existed. This thesis details the investigative and development work dedicated towards obtaining an ASR system with a 10000 word recognition vocabulary for the Indonesian language.

Boards of directors are key governancemechanisms in organizations and fulfill twomain tasks:monitoringmanagers and firm performance, and providing advice and access to resources. In spite of a wealth of researchmuch remains unknown about how boards attend to the two tasks. This study investigates whether organizational (firm profitability) and environmental factors (industry regulation) affect board task performance. The data combine CEOs' responses to a questionnaire, and archival data from a sample of large Italian firms. Findings show that past firm performance is negatively associatedwith board monitoring and advice tasks; greater industry regulation enhances perceived board task performance; board monitoring and advice tasks tend to reinforce each other, despite their theoretical and practical distinction.

This study examines the context of coordinated responses, triggers for coordinated responses, and preference for or choice of coordinating strategies in road traffic injury prevention at a local level in some OECD countries. This aim is achieved through a mixed-methodology. In this respect, 22 semi-structured interviews were conducted with road traffic injury prevention experts from five OECD countries. In addition, 31 professional road traffic injury prevention stakeholders from seven OECD nations completed a self-administered, online survey. It found that there was resource limitation and inter-dependence across actors within the context of road traffic injury prevention at a local level. Furthermore, this study unveiled the realization of resource-dependency as a trigger for coordinated responses at a local level. Moreover, the present examination has revealed two coordinating strategies favored by experts in road traffic injury prevention – i.e. self-organizing community groups, which are deemed to have a platform to deliver programs within communities, and the funding of community groups to forge partnerships. However, the present study did not appear to endorse other strategies such as the formalization of coordinated responses or a legal mandate to coordinate responses. In essence, this study appears to suggest a need to manage coordinated responses from an adaptive perspective with interactions across road traffic injury prevention programs being forged on a mutual understanding of inter-dependency arising out of resource scarcity. In fact, the role of legislation and top-down national models in local level management of coordinated responses is likely to be one of identifying opportunities to interact with self-organized community groups and fund partnership-based road traffic injury prevention events.

The driving force behind this study is the gap between the reality of the firms engaged in project business and the available studies covering project management and business process development. Previous studies show that project-based organizations were ‘immature’ in terms of the project-management ‘maturity model’, as few firms were found to be optimizing processes. Even within those, very little attention was paid to combine inter-organizational and intra-organizational perspectives. In this study an effort is made to elaborate some thoughts and views on project management, which interrelate firms’ external and internal activities. In line with the integration, the dissertation uses an approach to the management of project-business interdependencies in the networks of actors, activities and resources. Firstly, the study develops an understanding for inter-organizational perspectives by exploring the complementarities of process activities in the basic development of project business. It presents a framework that is elaborated on the basis of the reciprocal interactions of activities within and outside the organization—thus providing a coherent basis for continuous business-process improvement. In addition, the study presents new tools that can be used to develop project-business processes in each of its functional areas. The research demonstrates how project-business activities can be optimized using the right resources at the right time with the right actors and the right actions. The selected five articles included in this dissertation explain the basic framework for the development of project business. Each paper covers various aspects of inter-organizational and intra-organizational perspectives for project management. The study develops a valuable and procedural model for business-process improvement using the Delphi method that can be used not only in academia but also as a guide for practitioners that takes them through a series of well-defined steps when making informed, consistent and efficient changes to their business processes.

[EN] This study analyzes the relationship between board size and economic-financial performance in a sample of European firms that constitute the EUROSTOXX50 Index. Based on previous literature, resource dependency and agency theories, and considering regulation developed by the OECD and European Union on the normative of corporate governance for each country in the sample, the authors propose the hypotheses of both positive linear and quadratic relationships between the researched parameters. Using ROA as a benchmark of financial performance and the number of members of the board as measurement of the board size, two OLS estimations are performed. To confirm the robustness of the results the empirical study is tested with two other similar financial ratios, ROE and Tobin s Q. Due to the absence of significant results, an additional factor, firm size, is employed in order to check if it affects firm performance. Delving further into the nature of this relationship, it is revealed that there exists a strong and negative relation between firm size and financial performance. Consequently, it can be asseverated that the generic recommendation one size fits all cannot be applied in this case; which conforms to the Recommendations of the European Union that dissuade using generic models for all countries.

Cette recherche porte sur le financement public de l’enseignement supérieur au Pérou et ses impacts dans une perspective longitudinale couvant la période 1993-2003. Cette période est importante parce qu’elle a été témoin, dans ce pays, de changements majeurs aux plans du financement public et de la configuration du système d’enseignement supérieur. La recherche consiste principalement dans des analyses secondaires de données pertinentes publiées par des organismes nationaux et internationaux. Les analyses sont structurées à partir d’un schéma d’inputs et outputs. On considère comme inputs les ressources financières et les ressources humaines, lesquelles comprennent les professeurs et les étudiants, et comme outputs les taux de diplomation (efficacité interne) et la demande de diplômés par le marché du travail (efficacité externe). La théorie de la dépendance de ressources sert de cadre pour interpréter les rapports entre le financement public et ses incidences sur les réponses institutionnels et ses conséquences. Dans la période retenue, le financement du secteur public a décru de 32% en raison d’un désengagement progressif de l’État. Une conséquence majeure de la diminution du financement public a été la croissance rapide du secteur privé de l’enseignement supérieur. En effet, alors qu’en 1993 il y avait 24 institutions privées d’enseignement supérieur, il y en avait, en 2003, 46 institutions. La baisse du financement public et la croissance du secteur privé d’enseignement supérieur ont eu des incidences sur la sélectivité des étudiants, sur le statut des professeurs, sur l’implication des universités en recherche et sur les taux de diplomation. Le taux de sélectivité dans le secteur public a augmenté entre 1993 et 2003, alors que ce taux a diminué, dans la même période, dans le secteur privé. Ainsi, le secteur public répond à la diminution du financement en restreignant l’accès à l’enseignement supérieur. Le secteur privé, par contre, diminue sa sélectivité compensant ainsi l’augmentation de la sélectivité dans le secteur public et, par le fait même, augmente sa part de marché. Également, tant dans le secteur public que dans le secteur privé, les professeurs sont engagés principalement sur une base temporaire, ce qui se traduit, particulièrement dans le secteur privé, dans un moindre engagement institutionnel. Enfin, les universités publiques et privées du Pérou font peu de recherche, car elles favorisent, pour balancer leurs budgets, la consultation et les contrats au détriment de la recherche fondamentale. Paradoxalement, alors que, dans le secteur privé, les taux de sélectivité des étudiants diminuent, leurs taux de diplomation augmentent plus que dans le secteur public. Enfin, les formations avec plus d’étudiants inscrits, tant dans le secteur public que privé, sont les moins coûteuses en infrastructure et équipements. Dès lors, la pertinence de la production universitaire devient problématique. Cette recherche révèle que les organisations universitaires, face à un environnement où les ressources financières deviennent de plus en plus rares, développent des stratégies de survie qui peuvent avoir des incidences sur la qualité et la pertinence de l’enseignement supérieur.

Resource-based views of the firm and in particular Kay's (Why Firms Succeed. Oxford: Oxford Univ. Press, 1995) model of sustainable competitive advantage have been used to advance an understanding of differences in the competitive advantage of private-sector firms. We extend the analysis to a public-sector firm where its major purpose includes engaging in public good by giving away its knowledge base and services. The case highlights the paradox that many public-sector organizations face in simultaneously pursuing public good and sustainable competitive advantage. While Kay's model is applicable for understanding intergovernmental agency competition, we find it necessary to incorporate resource dependency theory to address the paradox. Implications for theory and practice are provided. (C) 2002 Elsevier Inc. All rights reseved.

Most advanced economies offer publicly financed advice services to start-up firms and SMEs. In England, local or regional Business Links organisations have provided these services, and divided their support into nonintensive one-off contacts providing information or advice and more intensive support involving a diagnostic process and repeated interaction with firms. A key choice for Business Link managers is how to shape their intervention strategies, balancing resources between intensive and nonintensive support. Drawing on resource dependency theory, we develop a typology of intervention strategies for Business Links in England which reflects differences in the breadth and depth of the support provided. We then test the impacts of these alternative intervention models on client companies using both subjective assessments by firms and econometric treatment models that allow for selection bias. Our key empirical result is that Business Links’ choice of intervention strategy has a significant effect both on actual and on perceived business outcomes, with our results emphasising the value of depth over breadth. The implication is that where additional resources are available for business support these should be used to deepen the assistance provided rather than extend assistance to a wider group of firms.

This thesis proposes to explore the potential for stakeholder based accounting as a means to explain the social performance of organisations. It argues that organisations have a contract with society and as a consequence they must be accountable to that society for their actions. Further, it is suggested that as part of this accountability there is a broader need in the public interest for social accounting. Due to the pluralistic nature of modern societies it is argued that a stakeholder framework is one way in which this accountability can be achieved. In order to consider the nature of such social accounting a case study of the electricity industry in England and Wales is undertaken. This industry is very important to modern society, has significant environment implications and has a recent history of remarkable change. These factors make it an interesting and unique case within which to consider accountability. From the performance measurement and accounting literature and a series of interviews with both stakeholders and privatised companies a model of stakeholder performance is developed. This is then used to analyse the electricity industry in England and Wales since privatisation. The objective is to demonstrate how certain stakeholders have fared, whether they have won or lost. Further, institutional and resource dependency theories are used to consider what factors determine the relative success or failure of the different stakeholder groups. Finally the possible implications of recent developments in Social Accounting Standards, such as the Global Reporting Initiative (GRI), AccountAbility 1000 (AA1000) and Social Accountability 8000 (SA8000), and the potential for Internet reporting are considered.

The study addresses the introduction of an innovation of new technology into a bureaucratic profession. The organisational setting is that of local authority secondary schools at a time at which microcomputers were being introduced in both the organisational core (for teaching) and its periphery (school administration). The research studies innovation-adopting organisations within their sectoral context; key actors influencing the innovation are identified at the levels of central government, local government and schools.A review of the literature on new technology and innovation (including educational innovation), and on schools as organisations in a changing environment leads to the development of the conceptual framework of the study using a resource dependency model within a cycle of the acquisition, allocation and utilisation of financial, physical and intangible resources. The research methodology is longitudinal and draws from both positivist and interpretive traditions. lt includes an initial census of the two hundred secondary schools in four local education authorities, a final survey of the same population, and four case studies, using both interview methods and documentation. Two modes of innovation are discerned. In respect of administrative use a rationalising, controlling mode is identified, with local education authorities developing standardised computer-assisted administrative systems for use in schools. In respect of curricular use, in contrast, teachers have been able to maintain an indeterminate occupational knowledge base, derived from an ideology of professionalism in respect of the classroom use of the technology. The mode of innovation in respect of curricular use has been one of learning and enabling. The resourcing policies of central and local government agencies affect the extent of use of the technology for teaching purposes, but the way in which it is used is determined within individual schools, where staff with relevant technical expertise significantly affect the course of the innovation.
