Projecting the U.S. gender wage gap 2000–40

This paper projects the gender wage gap for 25–64 year old Americans for the period 2000–40. The analysis uses data from the Panel Survey of Income Dynamics (PSID) for 1995 and 1996 together with the U.S. Census Bureau demographic projections. The method combines the population projections with assumptions regarding the evolution of educational attainment in order to first project the future distribution of skills and, based on these projections, the future size of the gender wage gap. The main set of projections suggests that changing skill characteristics—specifically educational attainment—will continue to close the gender wage gap. However, even in 2040, a substantial pay gap of at least 75 percent of the size of that in 1995 will remain.

Projections of the future path of the gender wage gap in Great Britain

Purpose – The paper attempts to project the future trend of the gender wage gap in Great Britain up to 2031. Design/methodology/approach – The empirical analysis utilises the British Household Panel Study Wave F together with Office for National Statistics (ONS) demographic projections. The methodology combines the ONS projections with assumptions relating to the evolution of educational attainment in order to project the future distribution of human capital skills and consequently the future size of the gender wage gap. Findings – The analysis suggests that gender wage convergence will be slow, with little female progress by 2031 unless there is a large rise in returns to female experience. Originality/value – The paper has projected the pattern of male and female skill acquisition together with the associated trend in wages up to 2031.

Consumer acceptance of m-wellbeing services : a social marketing perspective

Purpose This study aims to employ the Model of Goal-Directed Behaviour (MGB) to examine the consumer acceptance of technology-based self-service (TBSS) for a credence service instrumental to a social goal. Credence services are increasingly delivered via self-service technology and in social marketing, the achievement of social goals can be contingent on consumer acceptance of these services. However, little is known about the determinants of acceptance and extant marketing literature fails to account for emotional and goal influences which are likely to be important. Design/methodology/approach The authors interviewed 30 young adults with self-reported stress, anxiety or depression as potential users of a self-help mental health service delivered via mobile phone. The data were analysed deductively and inductively with the assistance of NVivo. Findings The findings generally support using the MGB to enhance understanding of consumers' acceptance of TBSS. The paper also found evidence of the importance of maintenance self-efficacy, the self-evaluation of the ability to continue using the service, and a previously ignored element of consumer level competition that arises between alternatives that achieve the same goal. Originality/value This study is the first to examine factors that influence consumers' acceptance of TBSS for credence services aimed at achieving a social goal. It builds on understanding of consumer decision making in social marketing, particularly the influence of self-efficacy and competition. It also contributes to attitudinal research by providing initial evidence for deepening and broadening the MGB in the context of TBSSs.

Closing the gap between copyright and designs : an age of enlightnement or state of confusion?

The arena of intellectual property encompasses streams that often interrelate and overlap in protecting different aspects of intellectual property. Australian commentators suggest that ‘one of the most troublesome areas in the entire field of intellectual property has been the relationship between copyright protection for artistic works under the Copyright Act 1968 (Cth) and protection for registered designs under the Designs Act 1906 (Cth).’ [McKeough, J., Stewart, A., & Griffith, P. (2004). Intellectual property in Australia (3rd ed.). Chatswood, NSW: Butterworths.] [Ricketson, S., Richardson, M., & Davison, M. (2009). Intellectual property: Cases, materials and commentary (4th ed.). Chatswood, NSW: LexisNexis Butterworths.] This overlap has caused much confusion for both creators of artistic works and industrial designs, as there is an uncertainty of whether protection against infringement is afforded under the Copyright Act 1988 (Cth) or whether the Designs Act 2003 (Cth) will apply. In Australia, there is limited precedent that examines the crossover between copyright and designs. Essentially, the cases that have tested this issue remain unclear as to whether a design applied industrially will invoke copyright protection. The cases demonstrate that there is an inconsistency in this area despite the aims of the new provisions of the Designs Act 2003 (Cth) to close the loopholes between copyright and designs. This paper will discuss and evaluate the relationship between copyright protection for artistic works and protection for registered designs with respect to the Designs Act 2003 (Cth).

Bridging the gap between tertiary education and work : situated learning in accountancy

In professions such as teaching, health sciences (medicine, nursing), and built environment, significant work-based learning through practica is an essential element before graduation. However, there is no such requirement in professional accounting education. This paper reports the findings of an exploratory qualitative case study of the implementation of a Workplace Learning Experience Program in Accountancy at the Queensland University of Technology (QUT) in Australia. The interview-based study documents the responses of university students and graduates to this program. The study demonstrates that a 100 hour work placement in Accountancy can enhance student learning. It highlights the potential value of the application of sociocultural theories of learning, especially the concept of situated learning involving legitimate peripheral participation (Lave and Wenger 1991). This research adds to a small body of empirical accounting education literature relating to the benefits of work placements prior to graduation. The effectiveness of this short, for credit, unpaid program should encourage other universities to implement a similar work placement program as a form of pre-graduation learning in professional accounting education.

Ratchetting of railhead in the vicinity of the gap of the insulated rail joints

Insulated Rail Joints (IRJs) are designed to electrically isolate two rails in rail tracks to control the signalling system for safer train operations. Unfortunately the gapped section of the IRJs is structurally weak and often fails prematurely especially in heavy haul tracks, which adversely affects service reliability and efficiency. The IRJs suffer from a number of failure modes; the railhead ratchetting at the gap is, however, regarded as the root cause and attended to in this thesis. Ratchetting increases with the increase in wheel loads; in the absence of a life prediction model, effective management of the IRJs for increased wagon wheel loads has become very challenging. Therefore, the main aim of this thesis is to determine method to predict IRJs' service life. The distinct discontinuity of the railhead at the gap makes the Hertzian theory and the rolling contact shakedown map, commonly used in the continuously welded rails, not applicable to examine the metal ratchetting of the IRJs. Finite Element (FE) technique is, therefore, used to explore the railhead metal ratchetting characteristics in this thesis, the boundary conditions of which has been determined from a full scale study of the IRJ specimens under rolling contact of the loaded wheels. A special purpose test set up containing full-scale wagon wheel was used to apply rolling wheel loads on the railhead edges of the test specimens. The state of the rail end face strains was determined using a non-contact digital imaging technique and used for calibrating the FE model. The basic material parameters for this FE model were obtained through independent uniaxial, monotonic tensile tests on specimens cut from the head hardened virgin rails. The monotonic tensile test data have been used to establish a cyclic load simulation model of the railhead steel specimen; the simulated cyclic load test has provided the necessary data for the three decomposed kinematic hardening plastic strain accumulation model of Chaboche. A performance based service life prediction algorithm for the IRJs was established using the plastic strain accumulation obtained from the Chaboche model. The predicted service lives of IRJs using this algorithm have agreed well with the published data. The finite element model has been used to carry out a sensitivity study on the effects of wheel diameter to the railhead metal plasticity. This study revealed that the depth of the plastic zone at the railhead edges is independent of the wheel diameter; however, large wheel diameter is shown to increase the IRJs' service life.

Safety at railway level crossings : driver acceptance of potential ITS interventions

There is a continuing need to improve safety at Railway Level Crossings (RLX) particularly those that do not have gates and lights regulating traffic flow. A number of Intelligent Transport System (ITS) interventions have been proposed to improve drivers’ awareness and reduce errors in detecting and responding appropriately at level crossings. However, as with other technologies, successful implementation and ultimately effectiveness rests with the acceptance of the technology by the end user. In the current research, four focus groups were held (n=38) with drivers in metropolitan and regional locations in Queensland to examine their perceptions of potential in-vehicle and road-based ITS interventions to improve safety at RLX. The findings imply that further development of the ITS interventions, in particular the design and related promotion of the final product, must consider ease of use, usefulness and relative cost.

Simulations of the spontaneous emission of a quantum dot near a gap plasmon waveguide

In this paper we modeled a quantum dot at near proximity to a gap plasmon waveguide to study the quantum dot-plasmon interactions. Assuming that the waveguide is single mode, this paper is concerned about the dependence of spontaneous emission rate of the quantum dot on waveguide dimensions such as width and height. We compare coupling efficiency of a gap waveguide with symmetric configuration and asymmetric configuration illustrating that symmetric waveguide has a better coupling efficiency to the quantum dot. We also demonstrate that optimally placed quantum dot near a symmetric waveguide with 50 nm x 50 nm cross section can capture 80% of the spontaneous emission into a guided plasmon mode.

Bridging the gap in school achievement through the arts : summary report

Educational Transformations Pty Ltd was commissioned by The Song Room (TSR) to conduct a study of the impact of TSR programs in government schools in relatively disadvantaged communities in New South Wales (NSW) on indicators of student performance that have been identified in previous research as related to potential engagement in juvenile crime. Students in Grades 5 and 6 were the subjects of study. TSR is a not-for-profit organisation in receipt of grants from public and private sources that conducts free programs in the performing arts in schools where these are not currently offered. These programs are conducted by mutual agreement between TSR and participating schools. Across Australia, approximately 200 schools and 40,000 students are engaged for a minimum of six months each year. Students typically participate for approximately one hour per week in each class. Instruction is provided by a Teaching Artist (TA), contracted to TSR and working in partnership with the classroom teacher at the school of placement. TSR received a three-year grant from the Macquarie Group Foundation to investigate the efficacy of its interventions in improving social and education outcomes for children in a range of high need target group areas participating in its program...

Rich evaluations of entertainment experience: bridging the interpretational gap

This paper reports a qualitative study of evaluating the ?experience? supported by a state-of-the-art interactive television application. Internet Protocol Television (IPTV) system is a new technology in the ever-growing industry of interactive entertainment. Focusing on the users? interpretations, we applied a set of rich evaluation strategies to collect data about users? experiences with the IPTV. The results show implications about how the users constructed complex and reflective understandings about the system. The evaluation suite helped us gather information about users? aspirations, expectations, and intellectual and emotional states of their understandings. The results also imply a strong support for taking into account the non-technical values of human-technology interaction.

Ambiguity Acceptance Testing : A Comparison of the Ratio Test and Difference Test

Integer ambiguity resolution is an indispensable procedure for all high precision GNSS applications. The correctness of the estimated integer ambiguities is the key to achieving highly reliable positioning, but the solution cannot be validated with classical hypothesis testing methods. The integer aperture estimation theory unifies all existing ambiguity validation tests and provides a new prospective to review existing methods, which enables us to have a better understanding on the ambiguity validation problem. This contribution analyses two simple but efficient ambiguity validation test methods, ratio test and difference test, from three aspects: acceptance region, probability basis and numerical results. The major contribution of this paper can be summarized as: (1) The ratio test acceptance region is overlap of ellipsoids while the difference test acceptance region is overlap of half-spaces. (2) The probability basis of these two popular tests is firstly analyzed. The difference test is an approximation to optimal integer aperture, while the ratio test follows an exponential relationship in probability. (3) The limitations of the two tests are firstly identified. The two tests may under-evaluate the failure risk if the model is not strong enough or the float ambiguities fall in particular region. (4) Extensive numerical results are used to compare the performance of these two tests. The simulation results show the ratio test outperforms the difference test in some models while difference test performs better in other models. Particularly in the medium baseline kinematic model, the difference tests outperforms the ratio test, the superiority is independent on frequency number, observation noise, satellite geometry, while it depends on success rate and failure rate tolerance. Smaller failure rate leads to larger performance discrepancy.

Consumer acceptance of Accountable-eHealth systems

In this paper, we present the results of a survey conducted to measure the attitudes of the consumers of eHealth towards Accountable-eHealth systems which are designed for information privacy management. A research model is developed that can identify the factors contributing to system acceptance and is validated using quantitative data from 187 completed survey responses from university students studying non-health related courses at a university in Queensland, Australia. The research model is validated using structural equation modelling and can be used to identify how specific characteristics of Accountable-eHealth systems would affect their overall acceptance by future eHealth consumers.

The role of perceived usefulness and attitude on electronic health record acceptance

Information and communications technologies are a significant component of the healthcare domain, and electronic health records play a major role in it. Therefore, it is important that they are accepted en masse by healthcare professionals. How healthcare professionals perceive the usefulness of electronic health records and their attitudes towards them have been shown to have significant effects on the overall acceptance in many healthcare systems around the world. This paper investigates the role of perceived usefulness and attitude on the intention to use electronic health records by future healthcare professionals using polynomial regression with response surface analysis. Results show that the relationships between these variables are more complex than predicted in prior research. The paper concludes that the properties of the above determinants must be further investigated to clearly understand: (i) their role in predicting the intention to use electronic health records; and (ii) in designing systems that are better adopted by healthcare professionals of the future.

Key facilitators and barriers to quality of life in residential aged care : the role of design

Australia is undergoing a critical demographic transition: the population is ageing. By 2050, one in four Australians will be older than 65 years and by 2031, the number of older Australians requiring residential aged care will increase 63%, to 1.4 million (ABS, 2005). In anticipation of this global demographic transition, the World Health Organisation has advocated ‘active ageing’, identifying health, participation and security as the three key factors that enhance quality of life for people as they age (WHO, 2002). While there is considerable discussion and acceptance of active ageing principles, little is known about the experience of ‘active ageing’ for older Australians who live in Residential Aged Care Facilities (RACF). This research addresses this knowledge gap by exploring the key facilitators and barriers to quality of life and active ageing in aged care from the perspective of aged care residents (n=12). To do this, the project documented the initial expectations and daily life experience of new residents living in a RACF over a one-year period. Combined with in-depth interviews and surveys, the project utilised Photovoice methodology - where participants used photography to record their lived experiences. The initial findings suggest satisfaction with living in aged care centers around five key themes; resident’s mental attitude to living in aged care, forming positive peer and staff relationships, self-determination and maintaining independence, opportunities to participate in interesting activities, and living in a safe and comfortable physical environment. This paper reports on the last of these five key themes, focusing on the role of design in facilitating quality of life, specifically: “living within these walls” – safety, comfort and the physical environment.
