This 
paper 
is
 based
 on 
a
 PhD 
thesis
 that investigated how Hollywood’s
dominance 
of
 the
 movie
 industry 
arose
 and
 how
 it
 has
 been
 maintained
over
time.
 Major 
studio
 dominance 
and
 the 
global
 popularity 
of
Hollywood
 movies has
 been
 the 
subject
 of
 numerous 
studies. 
An interdisciplinary
 literature 
review
 of 
the
 economics,
 management,
marketing,
 film,
 media
 and
 culture 
literatures
 identified
 twenty
 different 
single 
or
multiple 
factor
 explanations
 that 
try
 to
 account
 for
Major
 studio
 dominance 
at
 different
 time
 periods
 but
 cannot
comprehensively 
explain 
how 
Hollywood
 acquired
 and 
maintained
 global
 dominance 
for
 nine
 decades. 
Existing 
strategic
 management 
and
marketing
 theories
 were 
integrated 
into
 a 
‘theoretical
 lens’
 that
 enabled
a
 historical
 analysis
 of 
Hollywood’s
 longstanding 
dominance 
of
 the
movie
 business
 to
 be 
undertaken 
from 
a
 strategic
 business
 perspective.
 This
 paper
 concludes
 that 
the
 major 
studios 
rise 
to
 market 
leadership
 and 
enduring
 dominance
 can
 primarily
 be
 explained 
because 
they
 developed
 and 
maintained 
a 
set
 of
 strategic
 marketing
 management
 capabilities 
that
 were
 superior 
to rival
 firms
 and 
rival 
film 
industries. 
It
 is
 argued that 
a 
marketing
 orientation 
and 
effective
 strategic
 marketing
management
 capabilities 
also
 provide
a 
unifying
 theory
 for
 Hollywood’s
enduring 
dominance 
because 
they
 can 
account
 for
 each
 of
 the 
twenty
 previously
 identified
 explanations 
for 
that
 dominance.

Background: Cardiac patients with diabetes are at higher readmission rates (22%) compared to only 6% for those patients without diabetes. Evidence shows benefits of peer support and using information technology to improve chronic illness and achieve better health outcomes. However limited evidence suggests that cardiac or diabetes self-management programs incorporating peer supporters (patients with similar conditions) or telephone and text-messaging, have improved health outcomes and reduce health care utilisations. A multidisciplinary research team approach is crucial to accommodate the complex aspects of delivering intervention programs for these at-risk patients. However, challenges such as the inconsistency in significance of key concepts across research fields, as well as practical and operational issues within different contexts are often experienced. Aims: To develop an effective multidisciplinary team approach to deliver a peer support based cardiac-diabetes self-management program incorporating the preparation of lay personnel to provide telephone and text-messaging follow up support. Methods: The approach was used for a multidisciplinary project using randomised controlled trial. Results: The findings from multidisciplinary team approach reveal the feasibility of a Peer support based cardiac-diabetes self-management program.

The paper examines the impact of the introduction of no-fault divorce legislation in Australia. The approach used is rather novel, a hazard model of the divorce rate is estimated with the role of legislation captured via a time-varying covariate. The paper concludes that contrary to US empirical evidence, no-fault divorce legislation appears to have had a positive impact upon the divorce rate in Australia.

Effective Wayfinding is the successful interplay of human and environmental factors resulting in a person successfully moving from their current position to a desired location in a timely manner. To date this process has not been modelled to reflect this interplay. This paper proposes a complex modelling system approach of wayfinding by using Bayesian Networks to model this process, and applies the model to airports. The model suggests that human factors have a greater impact on effective wayfinding in airports than environmental factors. The greatest influences on human factors are found to be the level of spatial anxiety experienced by travellers and their cognitive and spatial skills. The model also predicted that the navigation pathway that a traveller must traverse has a larger impact on the effectiveness of an airport’s environment in promoting effective wayfinding than the terminal design.

Enterprise Systems (ES) provide standardized, off-theshelf support for operations and management within organizations. With the advent of ES based on a serviceoriented architecture (SOA) and an increasing demand of IT-supported interorganizational collaboration, implementation projects face paradigmatically new challenges. The configuration of ES is costly and error-prone. Dependencies between business processes and business documents are hardly explicit and foster component proliferation instead of reuse. Configurative modeling can support the problem in two ways: First, conceptual modeling abstracts from technical details and provides more intuitive access and overview. Second, configuration allows the projection of variants from master models providing manageable variants with controlled flexibility. We aim at tackling the problem by proposing an integrated model-based framework for configuring both, processes and business documents, on an equal basis; as together, they constitute the core business components of an ES.

The configuration of comprehensive Enterprise Systems to meet the specific requirements of an organisation up to today is consuming significant resources. The results of failing implementation projects are severe and may even threaten the organisation’s existence. This paper proposes a method which aims at increasing the efficiency of Enterprise Systems implementations. First, we argue that existing process modelling languages that feature different degrees of abstraction for different user groups exist and are used for different purposes which makes it necessary to integrate them. We describe how to do this using the meta models of the involved languages. Second, we motivate that an integrated process model based on the integrated meta model needs to be configurable and elaborate on the mechanisms by which this model configuration can be achieved. We introduce a business example using SAP modelling techniques to illustrate the proposed method.

This thesis investigates the role of narrative devices in the process of improving an individual’s psychological and physiological experience of health and well-being using two methods of inquiry: a theoretical research project and a comparative analysis of two case studies. Through these two approaches the research examines how the health status of people experiencing disability can be re-positioned and re-designed to develop creative, narrative-based approaches to strengthen communication between the mainstream community and those marginalised by pathological, social and biological illness-centric policy. The theoretical section of the thesis examines two different, but complementary bodies of research: health and well-being, and narrative reconstruction. By invoking Antonovksy’s (1985a) theory of salutogenesis and Davis’s (2002) theory of dismodernism, the study examines the role of language and narrative in the defining of health in social, pathological and ableist spheres. The research positions health and well-being as disparate from historical and contemporary readings of illness and disability and presents literature to support the potential to improve health well-being through a creative re-narration of the experience of disability. The research examines the theoretical concepts of resilience, autonomy and social inclusion through a detailed examination of narratology and the amnesty narrative. The study links these theoretical approaches to a practical Arts-Health intersection program developed for the research project called Communicating Personal Amnesty. Through a comparative analysis of a Pilot Study and Major Case study, the research presents findings derived from theory-building participatory action research showing the efficacy of the program. The research provides a detailed analysis of key narrative structures through a variety of experimental methodological approaches to encourage an important dialogue between the creative components of the thesis and the more traditional health-based academic critique. The research is an example of emergent translational health methodologies, in disability studies.

Australian journalism schools are full of students who have never met an Aboriginal or Torres Strait Island person and who do not know their history. Journalism educators are ill-equipped to redress this imbalance as a large majority are themselves non-Indigenous and many have had little or no experience with the coverage of Indigenous issues or knowledge of Indigenous affairs. Such a situation calls for educational approaches that can overcome these disadvantages and empower journalism graduates to move beyond the stereotypes that characterize the representation of Indigenous people in the mainstream media. This article will explore three different courses in three Australian tertiary journalism education institutions, which use Work-Integrated Learning Approaches to instil the cultural competencies necessary to encourage a more informed reporting of Indigenous issues. The findings from the three projects illustrate the importance of adopting a collaborative approach by industry, the Indigenous community and educators to encourage students’ commitment to quality journalism practices when covering Indigenous issues.

We propose a new active noise control (ANC) technique. The technique has a feedback structure to have a simple configuration in practical implementation. In this approach, the secondary path is modelled online to ensure convergence of the system as the secondary paths are practically time varying or non-linear. The proposed method consists of two steps: a noise controller which is based on a modified FxLMS algorithm, and a new variable step size (VSS) LMS algorithm which is used to adapt the modelling filter with the secondary path. The proposed algorithm stops injection of the white noise at the optimum point and reactivate the injection during the operation, if needed, to maintain performance of the system. Eliminating continuous injection of the white noise increases the performance of the proposed method significantly and makes it more desirable for practical ANC systems. The computer simulations are presented to show the effectiveness of the proposed method.

The framework by which organizations are governed has been changed. A reason for this change is related with the force of stakeholders that compel the political power and the business society to review the ways in which companies are governed. Stakeholder thinking has gradually put this change at the center of research into business and society relations. Based on the stakeholder thinking, the corporate regulation framework has extended a new dimension in the business and society interface. This article assesses these issues.

The moral arguments associated with justice, fairness and communitarianism have rejected the exclusivity of cost‐benefit analysis in corporate governance. Particularly, the percepts of new governance (NG) have included distributive aspects in efficiency models focused on maximizing profits. While corporate directors were only assigned to look after the return of investment within the traditional framework of corporate governance (CG), NG has created the scope for them to look beyond the set of contractual liabilities. This article explores how and how far NG notions have contributed to the devolution of CG to create internal strategies focusing on actors, ethics and accountability in corporate self-regulation.

Discussing the normative arguments for the development of corporate social responsibility (CSR) is difficult but important. It is difficult/ as any argument for this development could be detrimental if it seems that it could narrow the scope of innovation in business and becomes a barrier to companies' usual business cases. It is important, as the civil society actors need the theoretical basis to further the instances of corporate irresponsibility to societies in an articulated way. Given this background, this article presents a detailed discussion on the 'legitimacy' argument as a normative basis for rising CSR. It is an analysis that runs counter to the functionalist economic arguments that mostly focus on the financial stakeholders and consider only the (allegedly free) 'market' outcomes.

A multivariate approach to bidding strategy is presented in comparison with previous standard approaches. An optimal formulation is derived and a method of parameter estimation proposed. A case study illustrates the derivation of optimal and other strategic mark up values against a single bidder. Concluding remarks concern extensions to multiple competitors differing levels of information, and sensitivity analysis.
