Part-time Employment, Gender and Employee Participation in the Workplace: An Illawarra Reconnaissance

The growth in non-standard forms of employment has major implications for the effectiveness of employee participation mechanisms in the workplace, whether direct or indirect (representative). This seems to be especially the case with representative forms, such as consultative committees, because they effectively assume permanent or long-term employment and are not as easily accessible to part-time employees. However, the literature on participation rarely addresses this major contextual aspect. The issue is of further significance since the majority of part-time and casual employees are female. Consequently, to the extent that non-standard employees do not have the same access to participatory mechanisms in the workplace that their full- time permanent colleagues enjoy, then women also are disproportionately excluded from participation. This paper begins to redress the insularity in the literature by analysing survey data from the Illawarra Regional Industrial Relations Survey (IRWIRS). It tests the hypothesis that the growth of non-standard forms of employment diminishes the access to participation in the workplace enjoyed by part-time workers in comparison with their full-time colleagues.Illawarra Regional Workplace Industrial Relations Survey, workplace employee relations, Australia

Electroabsorption measurements of conjugated organic materials

This thesis reports the results of electroabsorption measurements undertaken on three materials that are all, to some degree, conjugated: polymeric and oligomeric emeraldine base, and polysquaraine. The aim of these experiments has been to investigate the nature of the optical excitations occuring within the materials. Electroabsorption (EA) spectroscopy involves the measurement of the change in absorption coefficient of a material with the application of an external field. The fields required are high and the resulting signals small, hence to perform such experiments a dedicated spectrometer was constructed. To achieve high sensitivity lock-in amplification techniques were used, and the sample kept at low temperatures. Such techniques resulted in the spectrometer being able to resolve changes in absorption of the order 1 in 5x10(^7).The sample configuration consisted of thin films of the materials which were spun coated onto sapphire substrates, with interdigitated gold electrodes deposited on top. This configuration allowed the absorption of the material to be measured while alternating fields of up to 200 kVcm(^-1) were applied. The EA data of the oligomeric and polymeric emeraldine base are seen to closely resemble each other - indicating that the same photoexcitation processes are occurring. Using existing theories the spatial extent of the 2 eV excitation is calculated as -0.4 nm, i.e. greater than one phenyl ring repeat unit. This is consistent with previously suggested models of 2 eV photoexcitation in emeraldine base. Similar calculations suggest a spatial extent of the 4 eV transition of -0.25 nm, i.e. restricted to one phenyl ring. A feature in the EA spectra of the oligomeric emeraldine base has been observed at 1.35 eV - below the onset of linear absorption, and it is suggested that this may be evidence of a normally one photon forbidden transition becoming allowed in the presence of an external field. Due to the fully conjugated nature of polysquaraine a different model has been used to interpret the EA spectrum. An energy level scheme for the material is suggested, including the possible location of a normally one photon forbidden transition at 1.75 eV

Gender, Part-time Employment and Employee Participation in the Workplace: Comparing Australia and the European Union

The international trend in the growth and incidence of 'no n-standard employment', and its highly gendered nature, is well documented. For ease of definition, and because of the nature of the available data, we focus upon part-time employment in this paper. Employee participation may be defined as any workplace process which 'allows employees to exert some influence over their work and the conditions under which they work' (Strauss 1998). It may be divided into two main approaches, direct participation and indirect or representative participation. Direct participation involves the employee in job or task-oriented decision-making in the production process at the shop or office floor level. Indirect or representative forms of participation include joint consultative committees, works councils, and employee members of boards of directors or management. In the EU context statutory works councils are the most common expression of representative participation, but in Australia, consultative committees resulting from union/employer agreement or unilateral management initiative are the more common form. All of these forms of employee participation raise important issues concerning part time employees. Effective participation has two further major requirements which also may disadvantage part timers. First, there is a ge neral consensus in the participation literature that training is required for effective direct or representative participation. Secondly, effective communication between management and employees is required for participation, preferably involving a two-way information flow. The issue is of further significance since it has decided gender implications. This paper seeks to redress this relative insularity in the literature by examining some broad trends in this area in Australia and the EU. It analyses survey data at a national level in Australia and compares with some survey data generated in the EU by the EPOC project and analysed by Juliet Webster along the lines which we suggest here. It tests the hypothesis that the growth of one non-standard form of employment, part-time employment, diminishes the access to participation in the workplace enjoyed by female workers in comparison with their male colleagues, and finds that the hypothesis is strongly confirmed. This has major implications for workplace equity, and for organisational efficiency.gender, part-time employment, employee participation, Australia, European Union

Use of magnetic compression to support turbine engine rotors

Ever since the advent of gas turbine engines, their rotating disks have been designed with sufficient size and weight to withstand the centrifugal forces generated when the engine is operating. Unfortunately, this requirement has always been a life and performance limiting feature of gas turbine engines and, as manufacturers strive to meet operator demands for more performance without increasing weight, the need for innovative technology has become more important. This has prompted engineers to consider a fundamental and radical breakaway from the traditional design of turbine and compressor disks which have been in use since the first jet engine was flown 50 years ago. Magnetic compression aims to counteract, by direct opposition rather than restraint, the centrifugal forces generated within the engine. A magnetic coupling is created between a rotating disk and a stationary superconducting coil to create a massive inwardly-directed magnetic force. With the centrifugal forces opposed by an equal and opposite magnetic force, the large heavy disks could be dispensed with and replaced with a torque tube to hold the blades. The proof of this concept has been demonstrated and the thermal management of such a system studied in detail; this aspect, especially in the hot end of a gas turbine engine, remains a stiff but not impossible challenge. The potential payoffs in both military and commercial aviation and in the power generation industry are sufficient to warrant further serious studies for its application and optimization

Increasing eigenstructure assignment design degree of freedom using lifting

This paper presents the exposition of an output-lifting eigenstructure assignment (EA) design framework, wherein the available EA design degrees of freedom (DoF) is significantly increased, and the desired eigenstructure of a single-rate full state feedback solution can be achieved within an output feedback system. A structural mapping is introduced to release the output-lifting causality constraint. Additionally, the available design DoF can be further enlarged via involving the input-lifting into the output-lifting EA framework. The newly induced design DoF can be utilised to calculate a structurally constrained, causal gain matrix which will maintain the same assignment capability. In this paper, the robustification of the output-lifting EA is also proposed, which allows a trade-off between performance and robustness in the presence of structured model uncertainties to be established. A lateral flight control benchmark in the EA literature and a numerical example are used to demonstrate the effectiveness of the design framework

Treatment of transient phenomena in analysis of slag-metal-gas reaction kinetics

Equations commonly used in describing reaction kinetics are examined and the problem of applying such equations to transient processes is discussed. Three examples of transient phenomena are examined in detail. It is shown that for carbon injection into slag, the reaction can be described by employing data for carbon oxidation in CO/CO2 by assuming reaction conditions approximately halfway between those in equilibrium with the slag and those in equilibrium with carbon. It is demonstrated that, when the time averaged interfacial area is employed, the rate of reaction between slag and iron-aluminum alloys can be described by a single first order rate equation, accommodating a 300% change in interfacial area. Creation of surface area in oxygen steelmaking is discussed and a method to determine the size distribution of droplets that are generated is proposed. It is concluded that changes in conditions during reaction complicate the analysis of kinetics. However, it should be possible to develop quantitative kinetic models to describe real processes

Long-Term Follow-Up of Patients Immunized with AN1792: Reduced Functional Decline in Antibody Responders

BACKGROUND: Immunization of patients with Alzheimer's disease (AD) with synthetic amyloid-beta peptide (Abeta(42)) (AN1792) was previously studied in a randomized, double-blind, placebo-controlled phase 2a clinical trial, Study AN1792(QS-21)-201. Treatment was discontinued following reports of encephalitis. One year follow-up revealed that AN1792 antibody responders showed improvements in cognitive measures as assessed by the neuropsychological test battery (NTB) and a decrease in brain volume compared with placebo. METHODS: A follow-up study, Study AN1792(QS-21)-251, was conducted to assess the long-term functional, psychometric, neuroimaging, and safety outcomes of patients from the phase 2a study 4.6 years after immunization with AN1792. The results were analyzed by comparing patients originally identified as antibody responders in the AN1792 phase 2a study with placebo-treated patients. RESULTS: One hundred and fifty-nine patients/caregivers (30 placebo; 129 AN1792) participated in this follow-up study. Of the 129 AN1792-treated patients, 25 were classified in the phase 2a study as antibody responders (anti-AN1792 titers > or = 1:2,200 at any time after the first injection). Low but detectable, sustained anti-AN1792 titers were found in 17 of 19 samples obtained from patients classified as antibody responders in the phase 2a study. No detectable anti-AN1792 antibodies were found in patients not classified as antibody responders in the phase 2a study. Significantly less decline was observed on the Disability Assessment for Dementia scale among antibody responders than placebo-treated patients (p=0.015) after 4.6 years. Significant differences in favor of responders were also observed on the Dependence Scale (p=0.033). Of the small number of patients who underwent a follow-up MRI, antibody responders showed similar brain volume loss during the follow-up period subsequent to the AN1792 phase 2a study compared with placebo-treated patients. CONCLUSIONS: Approximately 4.6 years after immunization with AN1792, patients defined as responders in the phase 2a study maintained low but detectable, sustained anti-AN1792 antibody titers and demonstrated significantly reduced functional decline compared with placebo-treated patients. Brain volume loss in antibody responders was not significantly different from placebo-treated patients approximately 3.6 years from the end of the original study. No further cases of encephalitis were noted. These data support the hypothesis that Abeta immunotherapy may have long-term functional benefits

Impact of a Pilot Outreach Program upon Provider Awareness and Prescribing of a Concerning Opioid Combination Regimen

This pilot program was developed in response to a drug utilization review within a large Medicaid population that revealed some hazardous practices. Co-prescribing of opioids with benzodiazepines, gabapentin, and other stimulants occurred in more than 500 members, putting them at risk for additive central nervous system depression, misuse, abuse, and death from overdose. The poster presentation outlines the objectives, methods, and results of a telephonic outreach program that addressed these safety concerns. It captures prescriber awareness of the presence and risks of potentially deadly medication combinations among members in their care, with some intriguing results. Our experts provide health plans with framework and support to address the opioid epidemic head on with robust opioid medication management programs, evidence-based clinical guidelines, and prescriber outreach. Our interdisciplinary team’s innovative approach helps health plans decrease inappropriate opioid usage and while ensuring members maintain access to appropriate pain management.
