Weaving the web - From myth to modernity

The discovery, development or invention of new objects and phenomena by humankind, requires a new set of words to be coined or adopted to describe it. This is also true of the Information Communication Technology (ICT) world. Words are not neutral, regardless of which dialect or language they occur in. They carry with them associations and connotations based on their previous applications and alliances, and augmented by their shapes, sounds, rhymes and rhythms. The subtext that word choice creates, while often not recognised or acknowledged, is important in considering how communication operates in, and shapes Information Technology (IT) environments. Many words that are now embedded in the ICT lexicon continue to be informed by these earlier meanings, some of which, in the English lexis, are drawn from myths. The vernacular of the ICT lexis reflects its openness to new ideas, the nature of its users, its English language roots and its Western cultural origins. This contributes to a particular communication style. But such lexis can prove problematic for non-English speaking background users and/or those from different cultures. As the ICT vocabulary continues to evolve, these language and cultural underpinnings are coming under challenge, suggesting a language and cultural future very different to the past. This in turn, will create a subtext that affects all users.

Internal auditor perceptions on audit committee interactions : a qualitative study in Malaysian public corporations

Audit committees (AC) and the internal audit function (IAF) are two key corporate governance mechanisms. The primary objective of this study is to provide insights into internal auditors' perceptions of their interactions with AC members in Malaysia. The paper thus contributes to the extant literature by providing additional evidence from a South-east Asian country which is recognised as being characterised with a high power distance culture and a developing capital market. The findings are based on in-depth interviews of the heads of the internal audit function (HIAFs) from 11 publicly listed companies. The results indicate infrequent informal communications and limited private meetings between the HIAFs and ACs, and a need for clear reporting lines. Further, ACs are seen to be held in high esteem for their authority and are expected to take on greater leadership in the inquiry of management's decision-making. These findings highlight the importance of the leadership role of ACs in supporting the IAF.

Who will be an entrepreneur? How cultural mechanisms and social network structure together influence entrepreneurial participation

Using data collected from 35 countries over five years, this study provides an investigation of the combined influence of cultural factors and social network structure on whether or not an individual, anywhere in the world, becomes an entrepreneur. Results show that knowing someone who has started a business recently, across the world, has a significant impact on entrepreneurship participation. Regarding the potential cultural influences, it seems that importance attached to personally knowing entrepreneurs differs significantly between individuals operating in different cultures. In cultures with high power distance, personally knowing a person who recently started a business is relatively less important as a driver of entrepreneurship participation compared to cultures with low power distance. On the other hand, in cultures where the Hofstede’s ‘masculinity’construct predominates, it is more important than in cultures characterised by ‘femininity’.

Cultural influence on global assessment of higher education service quality: The case of Central Queensland University, Australia

© 2014 by IGI Global. All rights reserved. This study compares students' cultural influence on global assessment of higher education service quality. In particular, this study surveyed the full-time students (that is at least 24 credit points of study in a semester) studying at the Central Queensland University (CQU), Australia. CQU has ten campuses and is one of the largest universities in Australia, with more than 14,000 students, in which 3,000 students are enrolled as full-time students and 11,000 as part-time students. An online survey was undertaken, and 227 responses from full-time students were returned for data analysis. Exploratory factor analysis and confirmatory factor analysis were performed to determine valid and reliable dimensions of perceived service quality. Tests of differences such as ANOVA and t-test were conducted to examine the differences of perceived service quality in terms of four cultural dimensions; namely, power distance, individualism, uncertainty avoidance, and masculinity. Findings show that different cultures perceive service quality differently; especially administrative service quality and physical facilities service quality.

The influence of follower cultural orientation on attitudinal responses towards transformational leadership: evidence from the Chinese hospitality industry

In addition to extending the empirical investigation of the relationship between transformational leadership and follower affective commitment to the Chinese hospitality industry, this study makes a theoretical contribution by investigating the influence of individually held cultural values on this relationship. Building on previous research which has examined whether collectivism moderates the transformational leadership/affective commitment relationship, this study investigates the moderating effects of two additional cultural value orientations, namely power distance and uncertainty avoidance. Hierarchical regression analysis was utilized to analyse survey data from 398 employees of four Chinese hotels in Zhejiang Province. In addition to finding a positive relationship between transformational leadership and affective commitment, data analysis revealed that followers low in power distance exhibited higher levels of affective commitment when working under a transformational leader than those high in power distance. In addition, followers high in uncertainty avoidance and collectivism exhibited greater commitment when working under a transformational leader than those low in uncertainty avoidance and collectivism. These findings clearly indicate the importance of within-country cultural differences to the effectiveness of leaders in the workplace. © 2014 © 2013 Taylor & Francis.

Participative leadership and the organizational commitment of civil servants in China: The mediating effects of trust in supervisor

The present study examines whether participative leadership engenders organizational commitment amongst Chinese civil servants and analyses the mechanisms by which it transmits its effects. Confirmatory factor analysis and structural equation modelling revealed that there was a significant relationship between supervisor-level participative leadership and the affective and normative commitment of subordinates, but no relationship with continuance commitment. Affective trust was also identified as the mediator variable underlying the relationship between participative leadership and organizational commitment. We show that participative leadership of supervisors elicits higher levels of trust and leads subordinates to reciprocate through exhibiting higher levels of organizational commitment. Our study also reveals that Chinese civil servants who accept an unequal distribution of power between supervisors and subordinates typically exhibit lower levels of affective and normative commitment to the organization than those who do not. Our results provide greater support for the deepening of administrative reforms and the dissemination of participative leadership practices in China's new civil service system. © 2013 British Academy of Management.

A grid-based index method for time warping distance

Recently DTW (dynamic time warping) has been recognized as the most robust distance function to measure the similarity between two time series, and this fact has spawned a flurry of research on this topic. Most indexing methods proposed for DTW are based on the R-tree structure. Because of high dimensionality and loose lower bounds for time warping distance, the pruning power of these tree structures are quite weak, resulting in inefficient search. In this paper, we propose a dimensionality reduction method motivated by observations about the inherent character of each time series. A very compact index file is constructed. By scanning the index file, we can get a very small candidate set, so that the number of page access is dramatically reduced. We demonstrate the effectiveness of our approach on real and synthetic datasets.

Location based power control for mobile devices in a cellular network

This paper provides location estimation based power control strategy for cellular radio systems via a location based interference management scheme. Our approach considers the carrier-to-interference as dependent on the transmitter and receiver separation distance and therefore an accurate estimation of the precise locations can provide the power critical mobile user to control the transition power accordingly. In this fully
distributed algorithms, we propose using a Robust Extended Kalman Filter (REKF) to derive an estimate of the mobile user’s closest mobile base station from the user’s location, heading and altitude. Our analysis demonstrates that this algorithm can successfully track the mobile users with less system complexity, as it requires measurements from only one or two closest mobile base stations and hence enable the user to transmit at the rate that is sufficient for the interference management. Our power control
algorithms based on this estimation converges to the desired power trajectory. Further, the technique is robust against system uncertainties caused by the inherent deterministic nature of the mobility model. Through simulation, we show the accuracy of our prediction algorithm and the simplicity of its implementation.

Electromagnetic receiving properties of overhead power line

This paper examines the use of overhead power transmission lines as electromagnetic sensors for detecting electric discharges caused by defective power transmission equipment. The experimental study involved the use of a spark gap (point-point configuration) and two HV conductors of different lengths to simulate electric discharge that takes place on transmission line. The experimental results show that large amount of energy are coupled onto the conductors and the amount of electromagnetic energy is dependent on the length of the conductor and the distance between the source and the conductor.

Teaching for blended learning: research perspectives from on-campus and distance students

The concept of blended learning has begun to change the nature of all teaching and learning in higher education. Information and communication technologies have impacted by providing a means of access to digital resources and interactive communication for all courses and the blending of pedagogy and technology has produced a range of approaches to teaching and learning. This paper discusses the research literature and the writers’ research, defining what they have concluded are teaching practices that use the concept of blended learning effectively. In investigating how ICT can add variation for student learning, they analyze this from two dominant modes of pedagogy, learning environment and pedagogy through both on-campus and distance education. In both modes, students acknowledged the power and effectiveness of blended learning.

Distance, dialogue and difference : a postpositive approach to understanding distance education in Papua New Guinia

This study focuses on the experiences of a group of educators engaged in a professional development program by distance education in Papua New Guinea. The participants in this study have been keeping professional journals, for periods of up to three years, about their experiences of distance education. Their discourses have been used to form a ‘connected group’ of research participants, who use an action framework to focus on problematic issues surrounding distance education in Papua New Guinea. It is a piece of research, framed by critical theory, and characterised by participation, collaboration, reflexivity, reciprocity and empowerment. The process of the study is based in dialogue, and takes the view that research is constituted of a transformative perspective, which alters the way research participants understand the multiple realities in which they live and work, arid ultimately results in improvements in their lived experiences. The nature of the methodology privileges Voice' and a discourse of difference from each participant which contributes to the problematic nature of the study. The study has concerned itself, increasingly, with issues of power and control in the research process, and this has resulted in significant changes in the research as participants have become more conscious of issues such as distance, dialogue and difference. The study has evolved over a period of time in significant ways, and evidence is available that teachers in Papua New Guinea, despite structural and pedagogical barriers, are critically reflective and are able to transform their practice in ways which are consistent with social, cultural and political contexts in which they live and work. A number of 'local1 theories about research and distance education in Papua New Guinea are developed by the participants as they become informed about issues during the research. The practice of distance education and professional development, at personal and institutional levels, undergoes reconstruction during the life of the research and the study 'signals' other ways in which distance education and professional development may be reconstructed in Papua New Guinea.

Mercantilist Cinderella : Deakin University and the distance education student in the postmodern world

This is a thesis presented on the position of the distance education student at a distance education university in the present era. Traditionally, the distance education student has been a sort of Cinderella: marginalised, being constructed as some form of lesser version of the on campus one. A largely invisible part of the higher education system in Australia since 1911, the distance education student has really only come to be foregrounded in university education discourses from 1983 onwards. It was not until then that the distance education student emerged from ‘hidden pools’ identified by Karmel (1975), and since then the construction of this student has undergone a number of modifications, mapped in this thesis. At the same time university education itself has undergone a series of modifications, not least of which has been its taking on mercantilist overtones as investments made by students in their own careers and professional development. The modifications, also mapped in this thesis, have progressed to the stage where the construction of the old distance education student is now one of a flexible learner in a mercantilist system of university education. The notion of distance education and the distance education student has undergone significant shifts, redefinitions and constructions, which are tracked in this thesis. My research has focussed on a number of pertinent questions, based on a study of Deakin University and its practice since its establishment. The thesis draws on a number of works which have been informed by those of Foucault, and I have framed my research questions accordingly. I have asked why and how Deakin University came into being as a distance education provider at tertiary level. What were the conditions of its establishment and progression in relation to the political events, economic practices and communication technology in use over time? To consider such questions, I needed to analyse the changes that I had seen occurring in the context of wider restructurings in university education. These had occurred in the context of government forging a closer interconnectedness between education and national economic aims and objectives at the same time as it demanded greater productivity in the face of commercial and industrial sector pushes for applied knowledge. Poststructuralist philosophical developments offer tools to explore not only questions of power, but the practical outcomes of questions of power, and how the complicity of individuals is established. This thesis explores ways in which such considerations helped to shape the changing constructions of the distance education student from a marginalised, disadvantaged and under-represented participant in higher education to a privileged, well catered for and advantaged learner. These same considerations are used to explore ways in which they have helped to shape university distance education courses from a perceived second-rate form of higher education to a prototype that better captures the essential elements of learning for what has been styled in a postmodern world as the Information Age. Overlaid on these considerations is a changing view of the economics of such provision of higher education. It is anticipated that this thesis will contribute to developing new understandings of the construction of subjectivities in relation to the distance education university student specifically, and to the university student generally, in the postmodern world. The implications of this examination are not inconsiderable for students and academics in a self-styled Information Society.

Distance from shore positively influences alert distance in three wetland bird species

Behavioural responses of wetland fauna to humans constitutes a potential conservation threat, and may alter how animals use wetlands and their surrounds. We predicted that the farther from refuge (i.e. water) that terrestrially foraging rails occurred, the longer the distance at which they would become alert when approached. We found that the distance at which Eurasian Coot, Fulica atra, Purple Swamphen, Porphyrio porphyrio, and Dusky Moorhen, Gallinula tenebrosa became alert to an approaching predator (i.e. human) increased with distance from the shore of a wetland (species and starting distance were not significant but associated with low power). Thus, these behavioural measures suggest these birds use water in wetlands as a refuge from potential threats such as people. © 2014 Springer Science+Business Media Dordrecht.

Bone density and neuromuscular function in older competitive athletes depend on running distance

UNLABELLED: Individuals who are involved in explosive sport types, such as 100-m sprints and long jump, have greater bone density, leg muscle size, jumping height and grip strength than individuals involved in long-distance running. INTRODUCTION: The purpose of this study is to examine the relationship between different types of physical activity with bone, lean mass and neuromuscular performance in older individuals. METHODS: We examined short- (n = 50), middle- (n = 19) and long-distance (n = 109) athletes at the 15th European Masters Championships in Poznań, Poland. Dual X-ray absorptiometry was used to measure areal bone mineral density (aBMD) and lean tissue mass. Maximal countermovement jump, multiple one-leg hopping and maximal grip force tests were performed. RESULTS: Short-distance athletes showed significantly higher aBMD at the legs, hip, lumbar spine and trunk compared to long-distance athletes (p ≤ 0.0012). Countermovement jump performance, hop force, grip force, leg lean mass and arm lean mass were greater in short-distance athletes (p ≤ 0.027). A similar pattern was seen in middle-distance athletes who typically showed higher aBMD and better neuromuscular performance than long-distance athletes, but lower in magnitude than short-distance athletes. In all athletes, aBMD was the same or higher than the expected age-adjusted population mean at the lumbar spine, hip and whole body. This effect was greater in the short- and middle-distance athletes. CONCLUSIONS: The stepwise relation between short-, middle- and long-distance athletes on bone suggests that the higher-impact loading protocols in short-distance disciplines are more effective in promoting aBMD. The regional effect on bone, with the differences between the groups being most marked at load-bearing regions (legs, hip, spine and trunk) rather than non-load-bearing regions, is further evidence in support of the idea that bone adaptation to exercise is dependent upon the local loading environment, rather than as part of a systemic effect.
