Information Technology (IT) is an important resource that facilitates growth and development in both the developed and emerging economies. The increasing forces of globalization are creating a wider digital divide between the developed and emerging economies. The smaller emerging economies are the most venerable. Intense competition for IT resources means that these emerging economies would need to acquire a deeper understanding of how to source and evaluate their IT-related efforts. This effort would put these economies in a better position to source funding from various stakeholders. This research presents a complementary approach to securing better IT-related business value in organizations in the South Pacific Island countries – a case of emerging economies. Analysis of data collected from six South Pacific Island countries suggests that organizations that invest in IT and related complementaries are able to better their business processes. The data also suggest that improved business processes lead to overall business processes improvements.

Purpose - The purpose of this paper is to examine post-graduate health promotion students’ self-perceptions of information literacy skills prior to, and after completing PILOT, an online information literacy tutorial. Design/methodology/approach – Post graduate students at Queensland University of Technology enrolled in PUP038 New Developments in Health Promotion completed a pre- and post- self-assessment questionnaire. From 2008-2011 students were required to rate their academic writing and research skills before and after completing the PILOT online information literacy tutorial. Quantitative trends and qualitative themes were analysed to establish students’ self-assessment and the effectiveness of the PILOT tutorial. Findings – The results from four years of post-graduate students’ self-assessment questionnaires provide evidence of perceived improvements in information literacy skills after completing PILOT. Some students continued to have trouble with locating quality information and analysis as well as issues surrounding referencing and plagiarism. Feedback was generally positive and students’ responses indicated they found the tutorial highly beneficial in improving their research skills. Originality/value - This paper is original because it describes post-graduate health promotion students’ self-assessment of information literacy skills over a period of four years. The literature is limited in the health promotion domain and self-assessment of post-graduate students’ information literacy skills. Keywords – Self-assessment, Post-graduate, Information literacy, Library instruction, Higher education, Health promotion, Evidence-based practice Paper Type - Research paper

Organizations today make radical use of the IT resources to sustain or better their existing competitive position. One such initiative is forming alliances on a shared IT backbone with partners of their value chain. We term these alliances the collaborative organizational structures (COS). Regardless of the nature of engagement with IT resources, organizations will require unique competencies to obtain performance-differentiating value from these IT resources. In a collaborative environment, these competencies would be a result of the synergy between the alliances’ unique competences. We call these the inter-firm IT-related capabilities. The resource centric theoretical frameworks suggest a trajectory of competence development and the structure of inter-firm competencies, but does not inform on the nature of these competencies. We employ an interpretive design to suggest three inter-firm IT-related capabilities for IT-backed collaborative alliances. We discuss these capabilities in this research and suggest that their effectiveness be measured directly against the collaborative rent, and indirectly against the firm-level performance of the alliance partners. This forms a model of leveraging and evaluating value within IT-backed collaborative alliances.

There is no doubt that information technology (IT) resources are important for organisations in any jurisdiction to manage their processes. Organisations consume considerable financial resources to acquire and manage their IT resources with various IT governance structures. Investment in IT, thus, is a strategic necessity. IT resources, however, do not contribute fully to business value on their own. Business value considers performance impacts of resources at various organisational levels (e.g., processes and firm levels). ITs are biased resources in that they require some form of manipulation to attain their maximum value. While we know that IT resources are important, a deeper understanding on two aspects of use of IT resources in organisations is important. First, is how to leverage the IT resources to attain its maximum value, and second, is where to evaluate IT-related business value in the organisation’s value chain. This understanding is important for organisation to sustain their operations in an ever-changing business environment. We address these issues in two parts. This paper discusses the first aspect of ways in which organisations can create and sustain their IT-related business value.

A deeper understanding on two aspects of use of IT resources in organisations is important to ensure sustainable investment in these IT resources. The first is how to leverage the IT resources to attain its maximum value. We discussed this aspect of use of IT resources in part 1 of this series. This discussion suggested a complementary approach as a first stage of IT business value creation, and dynamic capabilities approach to secure sustainable IT-related business value from the IT resources. The second important aspect of IT business value is where to evaluate IT-related business value in the organisations value chains. This understanding is important for organisations to ensure appropriate accountability of the investment and management of IT resources. We address this issue in this second part of the two part series.

This publication consists of a volume of papers presented at the workshop of the CIB Task Group 58: Clients and Construction Innovation, held on May 18- 19, 2009 at the University of Alberta in Edmonton, Canada. The workshop theme, “Leveraging Innovation for Sustainable Construction”, reflects a growing concern among clients for perspectives, approaches, and tools that will secure the practice of construction economically, socially, and environmentally. This collection encompasses some of the most incisive assessments of the challenges facing the construction industry today from a range of researchers and industry practitioners who are leading the way for tomorrow’s innovations. It provides a useful documentation of the ongoing conversation regarding innovation and sustainability issues and a foundation of knowledge for future research and development. The papers contained in this volume explore the workshop’s overarching theme of how to leverage innovation to increase the sustainability of the construction process and product. Participants sought to generate discussion on the topics of innovation and sustainability within the construction field, to share international examples of innovation from the research community and from industry, and to establish a point of reference for ongoing enquiry. In particular, our contributors have noted the value of learning through practice in order to orient research based on real-world industry experience. Chapters two and three present complementary models of sustainable research programs through the three parts collaboration of government, industry, and academia. Chapters four and five explore new tools and forms of technological innovation as they are deployed to improve construction project management and set the direction for advances in research. Chapters six, seven, and eight closely study practical examples of innovation in large-scale construction projects, showing with concrete results the impact of applying creative methods and best practices to the field. Innovation and sustainability in construction are truly global efforts; these papers illustrate how we can draw on international examples and cooperative organizations to address these important issues for long-term benefit of the industry.

A total histological grade does not necessarily distinguish between different manifestations of cartilage damage or degeneration. An accurate and reliable histological assessment method is required to separate normal and pathological tissue within a joint during treatment of degenerative joint conditions and to sub-classify the latter in meaningful ways. The Modified Mankin method may be adaptable for this purpose. We investigated how much detail may be lost by assigning one composite score/grade to represent different degenerative components of the osteoarthritic condition. We used four ovine injury models (sham surgery, anterior cruciate ligament/medial collateral ligament instability, simulated anatomic anterior cruciate ligament reconstruction and meniscal removal) to induce different degrees and potentially 'types' (mechanisms) of osteoarthritis. Articular cartilage was systematically harvested, prepared for histological examination and graded in a blinded fashion using a Modified Mankin grading method. Results showed that the possible permutations of cartilage damage were significant and far more varied than the current intended use that histological grading systems allow. Of 1352 cartilage specimens graded, 234 different manifestations of potential histological damage were observed across 23 potential individual grades of the Modified Mankin grading method. The results presented here show that current composite histological grading may contain additional information that could potentially discern different stages or mechanisms of cartilage damage and degeneration in a sheep model. This approach may be applicable to other grading systems.

The favourable scaffold for bone tissue engineering should have desired characteristic features, such as adequate mechanical strength and three-dimensional open porosity, which guarantee a suitable environment for tissue regeneration. In fact, the design of such complex structures like bone scaffolds is a challenge for investigators. One of the aims is to achieve the best possible mechanical strength-degradation rate ratio. In this paper we attempt to use numerical modelling to evaluate material properties for designing bone tissue engineering scaffold fabricated via the fused deposition modelling technique. For our studies the standard genetic algorithm was used, which is an efficient method of discrete optimization. For the fused deposition modelling scaffold, each individual strut is scrutinized for its role in the architecture and structural support it provides for the scaffold, and its contribution to the overall scaffold was studied. The goal of the study was to create a numerical tool that could help to acquire the desired behaviour of tissue engineered scaffolds and our results showed that this could be achieved efficiently by using different materials for individual struts. To represent a great number of ways in which scaffold mechanical function loss could proceed, the exemplary set of different desirable scaffold stiffness loss function was chosen. © 2012 John Wiley & Sons, Ltd.

Network RTK (Real-Time Kinematic) is a technology that is based on GPS (Global Positioning System) or more generally on GNSS (Global Navigation Satellite System) observations to achieve centimeter-level accuracy positioning in real time. It is enabled by a network of Continuously Operating Reference Stations (CORS). CORS placement is an important problem in the design of network RTK as it directly affects not only the installation and running costs of the network RTK, but also the Quality of Service (QoS) provided by the network RTK. In our preliminary research on the CORS placement, we proposed a polynomial heuristic algorithm for a so-called location-based CORS placement problem. From a computational point of view, the location-based CORS placement is a largescale combinatorial optimization problem. Thus, although the heuristic algorithm is efficient in computation time it may not be able to find an optimal or near optimal solution. Aiming at improving the quality of solutions, this paper proposes a repairing genetic algorithm (RGA) for the location-based CORS placement problem. The RGA has been implemented and compared to the heuristic algorithm by experiments. Experimental results have shown that the RGA produces better quality of solutions than the heuristic algorithm.

This article focuses on the well documented, yet potentially contested concept of rank-and-file policesubculture to conceptualize policeresponse to situations of domesticviolence in Singapore. It argues that the utility of the concept to explaining police behavior is often undermined by an all-powerful, homogenous, and deterministic conception of it that fails to take into account the value of agency in police decision-making and the range of differentiated policeresponse in situations of domesticviolence. Through reviewing the literature on policeresponse to domesticviolence, this study called for the need to rework the concept of policesubculture by treating it as having a relationship with, and response to, the structural conditions of policing, while retaining a conception of the active role played by street-level officers in instituting a situational practice. Using Pierre Bourdieu's relational concepts of ‘habitus’ and ‘field,’ designating the cultural dispositions of policesubculture and structural conditions of policing respectively, the study attempted to reconceptualize the problem of policing domesticviolence with reference to the Singaporean context.
