Service Quality Of Mhealth: Development And Validation Of A Hierarchical Model Using Pls, Shahriar Akter, John D'Ambra, Pradeep Ray 2010 University of Wollongong

Service Quality Of Mhealth: Development And Validation Of A Hierarchical Model Using Pls, Shahriar Akter, John D'Ambra, Pradeep Ray

Faculty of Commerce - Papers (Archive)

Advancing research on service quality requires clarifying the theoretical conceptualizations and validating an integrated service quality model. The purpose of this study is to facilitate and elucidate practical issues and decisions related to the development of a hierarchical service quality model in mobile health (mHealth) services research. Conceptually, it extends theory by reframing service quality as a reflective, hierarchical construct and modeling its impact on satisfaction, intention to continue using and quality of life. Empirically, it confirms that PLS path modeling can be used to estimate the parameters of a higher order construct and its association with subsequent consequential latent ...

The use of RFID tags in healthcare applications has been gaining momentum over the past decade. This is partly due to recent advances in information technology and the need to reduce errors while simultaneously improving the efficiency of the system. We, at the RFID European Lab, have been studying various aspects of RFID implementations in healthcare environment over the past several years. The potential for RFID implementations in healthcare environment is enormous. We consider several such opportunities and identify possible extensions.


Ownership And Ownership Concentration: Which Is Important In Determining The Performance Of China's Listed Firms?, Shiguang Ma, Tony Naughton, Gary Tian 2010 University of Wollongong

Ownership And Ownership Concentration: Which Is Important In Determining The Performance Of China's Listed Firms?, Shiguang Ma, Tony Naughton, Gary Tian

Faculty of Commerce - Papers (Archive)

This article investigates the impact of ownership and ownership concentration on the performance of China’s listed firms. By recognizing the differences between ownership and ownership concentration and between total ownership concentration and tradable ownership concentration, we find that ownership concentration is more powerful than any category of ownership in determining firm performance; tradable ownership concentration has a more significant and positive influence on firm performance than total ownership concentration; the highest level of firm performance is approached when a firm is characterized by both total ownership concentration and tradable ownership concentration. Thus, we propose a conclusion that ownership concentration ...


The Effect Of Motherhood On Wages And Wage Growth: Evidence For Australia, Tanya Livermore, Joan R. Rodgers, Peter Siminski 2010 Reserve Bank of Australia

The Effect Of Motherhood On Wages And Wage Growth: Evidence For Australia, Tanya Livermore, Joan R. Rodgers, Peter Siminski

Faculty of Commerce - Papers (Archive)

Labour market theory provides several reasons why mothers are likely to earn lower hourly wages than non-mothers. However, the size of any motherhood penalty is an empirical matter and the evidence for Australia is limited. This article examines the effect of motherhood on Australian women’s wages and wage growth using a series of panel-data models. Based on data from the Household, Income and Labour Dynamics in Australia survey, an unexplained motherhood wage penalty of around 5 per cent for one child, and 9 per cent for two or more children, is found. Further analysis suggests that the wage penalty ...

Faculty of Commerce - Papers (Archive)

This paper conveys the findings of a study conducted to evaluate the initiation of an interactive online computer-assisted learning module, called WEBLEARN, in an undergraduate introductory accounting course at an Australian university. The purpose was to aid students in the preparation of cash flow statements, a topic that from the student perspective is usually considered fairly difficult. Following the pilot of the module, student responses were collected via questionnaire in order to evaluate their perceptions regarding the WEBLEARN module. Diffusion of innovations theory was utilized as a framework for assessing student responses and to guide further development of modules in ...


Scale Dependence Of Lithological Control On Topography: Bedrock Channel Geometry And Catchment Morphometry In Western Scotland, John D. Jansen, Alexandru T. Codilean, Paul Bishop, Trevor B. Hoey 2010 University of Glasgow

Scale Dependence Of Lithological Control On Topography: Bedrock Channel Geometry And Catchment Morphometry In Western Scotland, John D. Jansen, Alexandru T. Codilean, Paul Bishop, Trevor B. Hoey

Faculty of Science - Papers (Archive)

We propose that a scale-dependent topographic signature of erodibility arises due to fiuvial and glacial erosion acting on different parts of the landscape at different times. For 14 catchments in western Scotland, we define three levels of substrate erodibility in order of decreasing resistance: quartzite rocks, nonquartzite rocks, and zones of fault-related fracture. Then, using digital topographic and planimetric data coupled with field measurements, we identify regression-based scaling relationships between substrate erodibility and morphometric parameters at two spatial scales. Catchment-scale morphometry shows a weak to variable relationship with substrate metrics overall. Erodibility can be inferred from catchment steepness indices (i ...

We use observations from the April 2008 NASA ARCTAS aircraft campaign to the North American Arctic, interpreted with a global 3-D chemical transport model (GEOS-Chem), to better understand the sources and cycling of hydrogen oxide radicals (HOx≡H+OH+peroxy radicals) and their reservoirs (HOy≡HOx+peroxides) in the springtime Arctic atmosphere. We find that a standard gas-phase chemical mechanism overestimates the observed HO2 and H2O2 concentrations. Computation of HOx and HOy gas-phase chemical budgets on the basis of the aircraft observations also indicates a large missing sink for both. We ...

We combine CO column measurements from the MOPITT, AIRS, SCIAMACHY, and TES satellite instruments in a full-year (May 2004–April 2005) global inversion of CO sources at 4◦ ×5◦ spatial resolution and monthly temporal resolution. The inversion uses the GEOS-Chem chemical transport model (CTM) and its adjoint applied to MOPITT, AIRS, and SCIAMACHY. Observations from TES, surface sites (NOAA/GMD), and aircraft (MOZAIC) are used for evaluation of the a posteriori solution. Using GEOSChem as a common intercomparison platform shows global consistency between the different satellite datasets and with the in situ data. Differences can be largely explained by different ...

The NASA Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) mission was conducted in two 3-week deployments based in Alaska (April 2008) and western Canada (June–July 2008). Its goal was to better understand the factors driving current changes in Arctic atmospheric composition and climate, including (1) influx of mid-latitude pollution, (2) boreal forest fires, (3) aerosol radiative forcing, and (4) chemical processes. The June–July deployment was preceded by one week of flights over California (ARCTAS-CARB) focused on (1) improving state emission inventories for greenhouse gases and aerosols, (2) providing observations to test and ...


What Drives The Choice Of A Third Party Logistics Provider?, Edward Anderson, Tim Coltman, Timothy Devinney, Byron Keating 2010 University of Sydney

What Drives The Choice Of A Third Party Logistics Provider?, Edward Anderson, Tim Coltman, Timothy Devinney, Byron Keating

Faculty of Commerce - Papers (Archive)

It is generally believed that companies choose supply chain partners on the basis of their distinctive value propositions – a fact one would also expect holds true when companies choose a logistics service provider. However, faced with the complexities of varied customer demands, it can be difficult for logistics service companies to obtain an effective understanding of how customers differentially value the service components they offer. In this paper, we address this by identifying the factors that are important in a customer’s choice of a logistics service provider. Using stated choice methods we explore the relative importance of seven service ...


Customer Relationship Management And Firm Performance, Tim Coltman, Timothy M. Devinney, David F. Midgley 2010 University of Wollongong

Customer Relationship Management And Firm Performance, Tim Coltman, Timothy M. Devinney, David F. Midgley

Faculty of Commerce - Papers (Archive)

In this paper, we examine the impact of customer relationship management (CRM) on firm performance using a hierarchical construct model. Following the resource-based view of the firm, strategic CRM is conceptualized as an endogenously determined function of the organization’s ability to harness and orchestrate lower order capabilities that comprise physical assets, such as IT infrastructure, and organizational capabilities, such as human analytics and business architecture. Our results reveal a positive and significant path between a superior CRM capability and firm performance. In turn, superior CRM capability is positively associated with human analytics and business architecture. However, our results suggest ...


Coping With Chaos: Unpredictable Food Supplies Intensify Torpor Use In An Arid-Zone Marsupial, The Fat-Tailed Dunnart (Sminthopsis Crassicaudata), Adam J. Munn, Pippa Kern, Bronwyn M. McAllan 2010 University of Sydney

The severity, duration and amplitude of extreme weather events are forecast to intensify with current climate trends, over both long (e.g. seasonal) and short (e.g. daily) time-scales. As such, the predictability of food supplies for many small endotherms is likely to become increasingly important. Numerous small mammals and birds combat food shortages using torpor, a controlled reduction in metabolic rate and body temperature that helps lower their daily energy requirements. As such, torpor often has been cited as a key feature allowing some small endotherms to survive highly unpredictable climates, such as tropics or dry deserts, but mensurative ...


One In Four Citations In Marine Biology Papers Is Inappropriate, Peter Todd, James Guest, Jinzhen Lu, Loke Ming Chou 2010 University of Singapore

One In Four Citations In Marine Biology Papers Is Inappropriate, Peter Todd, James Guest, Jinzhen Lu, Loke Ming Chou

Faculty of Science - Papers (Archive)

Citing sources that do not support the assertion being made can misinform readers, perpetuate mistakes and deny credit to the researchers who should have been acknowledged. To quantify citation fidelity in marine biology, we retrieved 198 papers from 2 recent issues of 33 marine biology journals. From each paper we randomly selected 1 citation, recovered the source material, and evaluated its appropriateness. We discovered that the assertion was ‘clearly supported’ by the citation in only 75.8% of cases, the support was ‘ambiguous’ in 10.6% of cases and the citation offered ‘no support’ to the original statement in 6 ...

Water is widely assumed to be essential for life, although the exact molecular basis of this requirement is unclear. Water facilitates protein motions, and although enzyme activity has been demonstrated at low hydrations in organic solvents, such nonaqueous solvents may allow the necessary motions for catalysis. To examine enzyme function in the absence of solvation and bypass diffusional constraints we have tested the ability of an enzyme, pig liver esterase, to catalyze alcoholysis as an anhydrous powder, in a reaction system of defined water content and where the substrates and products are gaseous. At hydrations of 3 (52) molecules of ...

Supply-Side Biogeography: Geographic Patterns Of Settlement And Early Mortality For A Barnacle Approaching Its Range Limit, Justin A. Lathlean, David J. Ayre, Todd E. Minchinton

Faculty of Science - Papers (Archive)

Species range limits are often associated with reduced adult densities, and this may reflect the failure of a particular life-history stage. For benthic marine invertebrates, settlement is a time of great mortality that strongly influences adult population structure, at least at local spatial scales. In south-eastern Australia we determined that adult abundance of the intertidal barnacle Tesseropora rosea declines over a 450 km region of rocky shore from the middle to the southern limit of its range, and we tested the hypothesis that this biogeographic pattern reflects variations in the production, settlement, or early post-settlement mortality of larvae or adult ...


Measures Of Taxonomic Distinctness Do Not Reliably Assess Anthropogenic Impacts On Intertidal Mollusc Communities, Trudy Costa, Timothy O'Hara, Michael Keough 2010 University of Wollongong

Measures Of Taxonomic Distinctness Do Not Reliably Assess Anthropogenic Impacts On Intertidal Mollusc Communities, Trudy Costa, Timothy O'Hara, Michael Keough

Faculty of Science - Papers (Archive)

Indices of taxonomic distinctness measure the taxonomic breadth of a community and may be more sensitive to human impacts than conventional diversity indices. They have the advantage of being, in theory, insensitive to sampling effort and can be calculated using presence/absence data. The average taxonomic distinctness index and variation in taxonomic distinctness index were used to assess the effects of putative human impacts on molluscan community composition at 63 rocky intertidal platforms on the coast of Victoria, Australia. The use of 2 sampling techniques, viz. timed searches and quadrats, was compared. Sites exposed to sewage discharge maintained high taxonomic ...

Management and conservation of ecosystems relies on biodiversity data; however, broad-scale biological data are often limited. Predictive modelling using environmental variables has recently proven a valuable tool in addressing this gap. Wave exposure is a particularly important environmental variable that structures shallow reef systems, but it is rarely quantified across the large areas often used for predictive studies. Therefore, we investigated approaches that quantify exposure and can be readily applied across a large area. We generated 6 quantitative indices that emphasise different aspects of exposure using a numerical wave model and cartographic fetch models. The utility of these indices for ...
