The Application Of Location Based Services In National Emergency Warning Systems: Sms, Cell Broadcast Services And Beyond, Anas Aloudat, Katina Michael 2011 University of Wollongong

The Application Of Location Based Services In National Emergency Warning Systems: Sms, Cell Broadcast Services And Beyond, Anas Aloudat, Katina Michael

Faculty of Informatics - Papers (Archive)

Location-based services can be broadly defined as any service that provides information pertinent to the current location of an active mobile handset at a specific window of time, regardless of the underlying delivery technology used to convey its information. To date, the short message service and cell broadcast service have been utilised by several countries during emergencies, however the future indicates that these services while cost-effective today, will almost certainly be superseded in the next five to ten years by newer more powerful capabilities. The path forward in location-based emergency services in Australia is given against a backdrop of the ...


The Role Of Dynamic Capabilities In Creating Business Value From Is Assets, Rajeev Sharma, Graeme Shanks 2011 University of Wollongong

The Role Of Dynamic Capabilities In Creating Business Value From Is Assets, Rajeev Sharma, Graeme Shanks

Faculty of Informatics - Papers (Archive)

This paper draws on and extends the emerging literature on dynamic capabilities to understand and explain the role ofinformation systems (IS) assets in creating business value. Our analysis identifies the critical roles of managerial actions andthe organizational context in identifying, resourcing and implementing IS-enabled competitive actions in delivering businessvalue. This paper extends earlier treatments of the relationship between IS assets and organizational strategy and performanceby explicitly accounting for the roles of human agency and context, which have not been adequately addressed in priorliterature. A research model for future research is proposed.

Location based social networking (LBSN) applications are part of a new suite of social networking tools. LBSN is the convergence between location based services (LBS) and online social networking (OSN). LBSN applications offer users the ability to look up the location of another “friend” remotely using a smart phone, desktop or other device, anytime and anywhere. Users invite their friends to participate in LBSN and there is a process of consent that follows. This paper explores the potential impact of LBSN upon trust in society. It looks at the willingness of individuals to share their location data with family, friends ...


Post-Release Mortality Of Angled Sand Mullet (Myxus Elongatus: Mugilidae), Matt K. Broadhurst, Paul A. Butcher, Brian R. Cullis 2011 NSW Department of Industry and Investment

Post-Release Mortality Of Angled Sand Mullet (Myxus Elongatus: Mugilidae), Matt K. Broadhurst, Paul A. Butcher, Brian R. Cullis

Faculty of Informatics - Papers (Archive)

Grey mullets (Mugilidae) are important to recreational fisheries throughout the developed world. In Australia, several species are angled and then released in large numbers; all with virtually unknown fate. In response to the need for such data to facilitate effective stock management, this study sought to quantify the post-release mortality and key causal factors for sand mullet (Myxus elongatus). A total of 125 fish were conventionally angled, and then released along with 50 controls into floating cages in a south eastern Australian estuary, where they were monitored for four days. Five treatment fish died, providing a non-significant mortality of 4 ...

With everyday objects becoming increasingly smart and the "info-sphere" being enriched with nano-sensors and networked to computationally-enabled devices and services, the way we interact with our environment has changed significantly, and will continue to change rapidly in the next few years. Being user-centric, novel systems will tune their behaviour to individuals, taking into account users' personal characteristics and preferences. But having a pervasive adaptive environment that understands and supports us "behaving naturally" with all its tempting charm and usability, may also bring latent risks, as we seamlessly give up our privacy (and also personal control) to a pervasive world of ...


Emerging Forms Of Covert Surveillance Using Gps-Enabled Devices, Roba Abbas, Katina Michael, M G. Michael, Anas Aloudat 2011 University of Wollongong

Emerging Forms Of Covert Surveillance Using Gps-Enabled Devices, Roba Abbas, Katina Michael, M G. Michael, Anas Aloudat

Faculty of Informatics - Papers (Archive)

This paper presents the real possibility that commercial mobile tracking and monitoring solutions will become widely adopted for the practice of non-traditional covert surveillance within a community setting, resulting in community members engaging in the covert observation of family, friends, or acquaintances. This paper investigates five stakeholder relationships using scenarios to demonstrate the potential socio-ethical implications that tracking and monitoring people will have on society at large. The five stakeholder types explored in this paper include: (i) husband-wife (partner-partner), (ii) parent-child, (iii) employer-employee, (iv) friend-friend, and (v) stranger-stranger. Mobile technologies such as mobile camera phones, global positioning system data loggers ...


Editorial: The Social And Behavioural Implications Of Location-Based Services, Katina Michael, M G. Michael 2011 University of Wollongong

Editorial: The Social And Behavioural Implications Of Location-Based Services, Katina Michael, M G. Michael

Faculty of Informatics - Papers (Archive)

The social and behavioral implications of location-based services (LBS) are only now beginning to come to light in advanced markets where the services have been adopted by just a little over half the market (Microsoft 2011). Depending on one's definition of what constitutes location-based services, statistics on the level of adoption differ considerably. While it is helpful to provide as broad a list of applications as possible in what constitutes LBS (e.g. everything from in-vehicle navigation systems to downloading a map using a computer), it can also cloud the real picture forming behind this emerging technology. Emerging not ...


Toward The Regulation Of Ubiquitous Mobile Government: A Case Study On Location-Based Emergency Services In Australia, Anas Aloudat, Katina Michael 2011 University of Wollongong

Toward The Regulation Of Ubiquitous Mobile Government: A Case Study On Location-Based Emergency Services In Australia, Anas Aloudat, Katina Michael

Faculty of Informatics - Papers (Archive)

Mobile alerts and notifications and location-based emergency warning systems are now an established part of mobile government strategies in an increasing number of countries worldwide. In Australia the national emergency warning system (NEWS) was instituted after the tragic Black Saturday Victorian Bushfires of February 2009. NEWS has enabled the provision of public information from the government to the citizen during emergencies anywhere and any time. Moving on from traditional short message service (SMS) notifications and cell broadcasting to more advanced location-based services, the paper explores the major issues faced by government, business and society at large, toward the realization of ...

Saint Augustine of Hippo (354-430 CE) [1] one of the most revered doctors of the ecclesia catholica, might not have been so highly esteemed had he fl ourished centuries afterwards in a world of uberveillance [2]. One of the unique aspects of Augustine's life that endeared him to the community of the faithful, both past and present, was his rising up from the "fornications" [3] and the "delight in thievery" [4] to become a paradigm for both the eastern and western churches of the penitent who becomes a saint.


Randomly Projected Kd-Trees With Distance Metric Learning For Image Retrieval, Pengcheng WU, Steven HOI, Duc Dung NGUYEN, Ying HE 2011 Nanyang Technological University

Randomly Projected Kd-Trees With Distance Metric Learning For Image Retrieval, Pengcheng Wu, Steven Hoi, Duc Dung Nguyen, Ying He

Research Collection School Of Information Systems

Efficient nearest neighbor (NN) search techniques for highdimensional data are crucial to content-based image retrieval (CBIR). Traditional data structures (e.g., kd-tree) usually are only efficient for low dimensional data, but often perform no better than a simple exhaustive linear search when the number of dimensions is large enough. Recently, approximate NN search techniques have been proposed for high-dimensional search, such as Locality-Sensitive Hashing (LSH), which adopts some random projection approach. Motivated by similar idea, in this paper, we propose a new high dimensional NN search method, called Randomly Projected kd-Trees (RP-kd-Trees), which is to project data points into a ...


A Low Complexity Resource Allocation Algorithm For Ofdma Cooperative Relay Networks With Fairness And Qos Guaranteed, Asem Salah, R. S.A.R. Abdullah, B. B. M. Ali, Nidhal Odeh 2011 Universiti Putra Malaysia

A Low Complexity Resource Allocation Algorithm For Ofdma Cooperative Relay Networks With Fairness And Qos Guaranteed, Asem Salah, R. S.A.R. Abdullah, B. B. M. Ali, Nidhal Odeh

Faculty of Informatics - Papers (Archive)

This paper proposes a new resource allocation algorithm for uplink OFDMA-based cooperative relay networks, assuming multiple user nodes, multiple relay nodes and a single destination. The aim is to maximise the total sum of the users' data rates, while guaranteeing fairness among them with different QoS requirements. Assuming perfect channel state information (CSI) at the resource allocation controller, the optimisation problem is formulated such that each user is assigned a weight factor based on its QoS requirements. The ones with higher weights are given higher priorities to select their resources (relay stations and subcarriers) first. Once the required QoS is ...


Controlling For Method Bias: A Critique And Reconceptualization Of The Marker Variable Technique, Philip Yetton, Rajeev Sharma, Jeff Crawford 2011 University of New South Wales

Controlling For Method Bias: A Critique And Reconceptualization Of The Marker Variable Technique, Philip Yetton, Rajeev Sharma, Jeff Crawford

Faculty of Informatics - Papers (Archive)

The marker variable technique is an easy-to-use technique for estimating the magnitude of method bias within a study. However, its validity has not yet been established. This paper addresses three issues assessing the validity of the technique and finds that it is subject to significant validity threats. A redefinition of the marker variable correlation is proposed, which partly addresses the theoretical critiques of the technique. The findings confirm Podsakoff et al.’s (2003) critique that the marker variable technique does not capture key sources of method bias. Implications of the findings for estimating and controlling for method bias within individual ...


Creating Value From Business Analytics Systems: A Process-Oriented Theoretical Framework And Case Study, Graeme Shanks, Nargiza Bekmamedov, Rajeev Sharma 2011 University of Melbourne

Creating Value From Business Analytics Systems: A Process-Oriented Theoretical Framework And Case Study, Graeme Shanks, Nargiza Bekmamedov, Rajeev Sharma

Faculty of Informatics - Papers (Archive)

Business analytics can potentially create value and improve competitive advantage for firms. We argue that dynamic and operational capabilities, enabled by business analytics technology, lead to improved firm performance. We develop a process-oriented theoretical framework that explains how dynamic and operational capabilities interact over time to create value. We use the framework to explain how business value was achieved from business analytics systems in a case study at a financial institution. A number of implications of the study are discussed and suggestions for future work are provided.


Improving Knowledge Sharing Behaviour Within Organizations: Towards A Model, Marion Zalk, Rachelle Bosua, Rajeev Sharma 2011 University of Melbourne

Improving Knowledge Sharing Behaviour Within Organizations: Towards A Model, Marion Zalk, Rachelle Bosua, Rajeev Sharma

Faculty of Informatics - Papers (Archive)

Knowledge management is the process of capturing, storing, sharing and using organizational knowledge with the aim of improving organizational performance. A necessary precursor for successful knowledge management initiatives is knowledge exchange between employees. This exchange is voluntary and highly dependent on an individual’s willingness to share his/her knowledge. It thus becomes important to identify the factors motivating employees to share their knowledge. This research in progress draws on Locke and Latham’s Goal Setting Theory (1990) to propose a model explaining knowledge sharing behavior.

Creating Value From Business Analytics Systems: The Impact Of Strategy, Graeme Shanks, Rajeev Sharma

Faculty of Informatics - Papers (Archive)

Business analytics systems can potentially contribute to firm performance and create competitive advantage. However, these benefits do not always follow from investment in business analytics technology. This paper argues that dynamic capabilities, enabled by business analytics technology, lead to value-creating actions and ultimately to improved firm performance. We develop a theoretical model that explains how organizational strategy relates to both business analytics technology and organizational structure, and impacts value-creating actions. We use the theoretical model to explain the implementation of a CRM system for one type of strategy.


Exploring The Role Of Ict In The Formation Of Transactive Memory Systems In Virtual Teams, Mohamed Imran Ariff, Simon K. Milton, Rachelle Bosua, Rajeev Sharma 2011 University of Melbourne

Exploring The Role Of Ict In The Formation Of Transactive Memory Systems In Virtual Teams, Mohamed Imran Ariff, Simon K. Milton, Rachelle Bosua, Rajeev Sharma

Faculty of Informatics - Papers (Archive)

This paper is a research in progress. Virtual teams (VTs) are increasingly common in organizations, yet explicit research on VTs’ performance is relatively rare. One of the key challenges faced by individuals in VTs is the awareness of ‘who knows what’ and ‘who does what’ in the team. One of the solutions offered by past research in overcoming these key challenges is for teams to form Transactive Memory Systems (TMS). However, previous research on TMS has been limited and focused primarily on face-to-face teams yielding inconsistent results with respect to TMS formation in VTs. Therefore, the goal of this research ...


Is It Easy Being Green? On The Dilemmas Of Material Cultures Of Household Sustainability, Chris Gibson, Gordon R. Waitt, Lesley M. Head, Nick Gill 2011 University of Wollongong

In the 1970s ‘greens’ were normally thought of as radicals because of their uncompromising political views about sustainability, non-violence, social justice and grassroots democracy. Sometimes greens were marginalised as ‘tree-huggers’ because of their affinity with the non-human world. Today, in popular discourse, ‘green’ provides the centre of sustainability gravity (Barr 2003). Green has become a definitive reflection of what individuals are to become as both consumers and citizens. It is easy, it is said, to be green. This is evident from product branding to categories used in government survey results to describe the ‘most acceptable’ household practices. But as green ...

Background: We present a lipidomics analysis of human Parkinson’s disease tissues. We have focused on the primary visual cortex, a region that is devoid of pathological changes and Lewy bodies; and two additional regions, the amygdala and anterior cingulate cortex which contain Lewy bodies at different disease stages but do not have as severe degeneration as the substantia nigra. Methodology/Principal Findings: Using liquid chromatography mass spectrometry lipidomics techniques for an initial screen of 200 lipid species, significant changes in 79 sphingolipid, glycerophospholipid and cholesterol species were detected in the visual cortex of Parkinson’s disease patients (n = 10 ...

Lutein From De-Epoxidation Of Lutein Epoxide Replaces Zeaxanthin To Sustain An Enhanced Capacity For Non-Photochemical Chlorophyll Fluorescence Quenching In Avocado Shade Leaves In The Dark, Britta Forster, Barry James Pogson, Charles Barry Osmond 2011 Australian National University

Lutein From De-Epoxidation Of Lutein Epoxide Replaces Zeaxanthin To Sustain An Enhanced Capacity For Non-Photochemical Chlorophyll Fluorescence Quenching In Avocado Shade Leaves In The Dark, Britta Forster, Barry James Pogson, Charles Barry Osmond

Faculty of Science - Papers (Archive)

Leaves of avocado (Persea americana Mill.) that develop and persist in deep shade canopies have very low rates of photosynthesis but contain high concentrations of lutein epoxide (Lx) that are partially de-epoxidized to lutein (L) after one hour exposure to 120 to 350 μmol photons m-2 s-1 increasing the total L pool by 5-10% (ΔL). De-epoxidation of Lx to L was near stoichiometric and similar in kinetics to de-epoxidation of violaxanthin (V) to antheraxanthin (A) and zeaxanthin (Z). Although the V pool was restored by epoxidation of A and Z overnight, the Lx pool was not. Depending on leaf age ...
