Specification Errors in Spatial Models: Impacts on Modeling and Estimation.
No full textA principal motivation for the research reported in this paper is to seek to understand what consequences can result from an erroneous specification of the lattice topology when an autoregressive spatial model is employed for inferential purposes. The first part of the discussion concerns impacts of such a specification error on the resulting dependence structure among data in SAR and CAR models. Although some ideas on this matter can be found in popular monographs about spatial statistics (Cliff and Ord 1981; Griffith 1988; Cressie 1993; Guyon 1995), the problem does not seem to have been attacked directly in the literature, two exceptions being Griffith (1995) and Griffith and Lagona (1997). In this paper an additional step is made in this direction, extensively using the theory of power series for matrices (see, for instance, Cooke 1950) and basic graph theory (see, for instance, Ore 1960). The second part of the discussion concerns impacts of a misspecified lattice topology on the quality of popular estimation procedures for SAR and CAR models. Because estimator quality can be measured by sampling distribution properties, unbiasedness and efficiency are considered here as basic measures of it. For this problem, a useful starting point is furnished by Oksanen (1991), and Cordey and Griffith's (1993) work is extended here. Much of the finite sample mathematical statistics summarized in this paper is numerically demonstrated in Griffith (1995). And, the Jacobian work outlined in Griffith and Sone (1995) is exploited to attain selected analytical results
Playing with Fire: Understanding the Sunni-Shi'a Sectarian Lifecycle
No full textThis article discusses the ingrained impediments which are likely to stifle India's rise and growth - a phenomenon which has figured prominently in scholarly and official assessments, in India and outside, for over a decade now. Intriguingly India's rise as a global power has already been adjudged a certainty in these assessments, but the author contends that there exists an apparent disjuncture between how the world sees India and the prevailing internal impediments. Therefore, any assessment of India as a global power without incorporating these impediments would be incomplete, misplaced and hyperbolic. Of late, in the light of India's growing internal and external socio-economic and political difficulties, more and more writings and proclamations by Indian and international experts indicate emerging scepticism over India's potential as a global power. This paper takes a rollcall of India's internal impediments including, human development, institutional and security challenges which according to the author have already begun restraining India's global ascent.Griffith Business School, Griffith Asia InstituteFull Tex
The link between product market reform and macro-economic performance
No full textValue-added per capita in EU countries has lagged behind the US. This is despite widespread reforms to product markets across EU countries aimed at increasing growth. This study analyses the macro-economic impact of product market reforms undertaken in the European Union over the 1980s and 1990s by examining a large number of regulations and reforms across EU countries.product market, product market reforms, regulations, macro-economic performance, allocative efficiency, productive efficiency, dynamic efficiency, aggregate economy, Griffith, Harisson
Reflections on the Choral Rehearsal Cycle: An Approach to Professional Practice
No full textThis dissertation explores and reflects on the professional practice of the author and a group of five experts through case studies. Incorporating interviews, observations, reflective journals, video footage, and a choral project, this research aims to explore how five expert choral conductors work in the rehearsal setting. Rehearsal techniques are as diverse as the individuals who practise them. Yet, even though conductors have their differences, the varied outcomes can still be judged as satisfactory. These techniques are not necessarily skills that have been taught in an undergraduate conducting class. Conducting courses and textbooks focus on beat patterns and other skills that must be mastered by the novice and which, in turn, lend themselves more readily to assessment. However, the running of a rehearsal is a complex mixture of musicianship and teaching skills that are continually developed over a lifetime of practice. The following questions emerge: how, then, do highly successful conductors work in rehearsal? What do they consider to be important parts of their own practice? What skills and attributes are crucial for successful ensemble leadership? For this research, five expert choral conductors were observed on site in multiple rehearsals and in working with a variety of vocal ensembles. They also participated in a wide-ranging, semistructured interview that further explored their approaches to conducting, repertoire selection, planning, personal philosophy, and reflections on their craft. The author used the data generated from the case studies and through a survey of core literature to experiment with their own practice during a 12-week rehearsal period that culminated in a performance of Haydn’s Missa in angustiis. The research project revealed that, while each case study conductor had an individualistic approach to their rehearsal delivery, five main characteristics appeared to be common amongst them all: they recognised the conductor’s role as a teacher; they were interested in working towards a sound ideal; they believed in their responsibility to develop skills; they included performance opportunities in the rehearsal setting; and they emphasised the importance of building community. As a result, these concepts formed the foundation of the author’s work with their own ensemble. These findings have implications for the author’s own practice as well as broader implications for other conductors and the training of student conductors. The results appear to advocate a more holistic approach to conducting and conductor training as well as the importance of developing community within the avocational choir.Thesis (Professional Doctorate)Doctor of Musical Arts (DMA)Queensland ConservatoriumArts, Education and LawFull Tex

Canyons and Ice: The Wilderness Travel of Dick Griffith
No full textDick Griffith journeyed across Alaska, Canada, Mexico, and the American West. According to Jon Krakauer, "Griffith is simply afflicted with an irresistible inclination to attempt what others say can't be done. When asked what possesses a man to repeatedly strike out alone across hundreds of miles of rugged, lonely country, he replies, 'Every so often, it's just time to walk.'" Kaylene Johnson is author of five books about Alaska including her memoir A Tender Distance: Adventures Raising My Son in Alaska
Prediction of Wave-Induced Seabed Maximum Liquefaction Depth Using Artificial Neural Network Model
No full textIn the last few decades, considerable effort has been devoted to the phenomenon of wave-induced liquefaction. In deed, it is one of the most important factors used in analysing
the seabed stability and in designing marine structures. As waves propagate and fluctuate
over the ocean surface, energy is carried within the medium of the water particles. When
this energy is transmitted into the seabed, the results are a rather complex mechanism of
soil behaviours that significantly affect the stability of the seabed.
The prediction of wave-induced seabed liquefaction has been recognised by coastal
geotechnical engineers as an important factor when considering the design of marine
structures. All existing prediction of wave-induced seabed liquefaction models have been
based on conventional approaches of engineering mechanics, with limited laboratory work.
Previous studies have involved complicated procedures and complex mathematical methods.
The present meticulous study has been based on the existing poro-elastic wave-induced
seabed liquefaction solution, and has adopted Artificial Intelligence (AI) technology to
predict maximum wave-induced seabed liquefaction. The author has proposed an alternative
approach for prediction of the maximum liquefaction depth, based on the Artificial
Neural Network (ANN). Unlike previous engineering mechanical approaches, the various
proposed ANN models are based on data learning knowledge, rather than on the knowledge
of the mechanisms. The author has concluded that ANN models can be applicable
to such engineering exercise at least this study.Thesis (PhD Doctorate)Doctor of Philosophy (PhD)Griffith School of EngineeringScience, Environment, Engineering and TechnologyFull Tex
Applying Service-Dominant Logic into the Procurement Function in Ghanaian Universities
No full textThe procurement function of universities in most developing countries has not been well researched. Within the procurement function, the role of service-dominant (S-D) logic is growing in interest. This thesis applies S-D logic to the procurement function in universities within a developing country context. The research investigates how the application of S-D logic into the procurement function can lead to improved procurement performance in universities. Emanating from the seminal work of Lusch and Vargo (2004a), S-D logic is perceived as a progressive business concept capable of creating value by transforming business processes and practices. Proponents of S-D logic argue that because firms do not possess all the resources necessary to be productive, there is the need to collaborate with other actors in business engagements to have shared access to resources in order to jointly create value (Vargo, 2008). The procurement function, a key component of supply network processes, ensures that goods and services are sourced and obtained. However, in order to ensure optimal performance processes need to be managed effectively. The procurement function in Ghana is transitioning from a back-office non-strategic activity to an effective socio-economic function, with the ability to influence decisions and create wealth for governments and the private sector alike (Knight et al, 2007).Thesis (PhD Doctorate)Doctor of Philosophy (PhD)Griffith Business SchoolGriffith Business SchoolFull Tex
