Environment friendly hydraulic lubricants – properties & performance.

 The present study aims to undertake research to improve the properties of vegetable oil based biodegradable lubricants for hydraulic oil applications. Different approaches were explored and adopted to investigate the thermo-oxidative stability, tribological property and corrosion behaviour of biodegradable basestocks as per the ISO 15380 specification.

A new biocompatible ionic liquid as an antiwear additive for biodegradable lubricants

A new biocompatible ionic liquid P1444DPP (IL1) was investigated as an antiwear additive and compared against Amine Phosphate (AP), one of the commonly used conventional antiwear additives in various biodegradable base stocks. In general, such base stocks (vegetable oil and synthetic esters) are being used for preparing biodegradable industrial lubricants. To further check its efficacy, the results were also compared with one of the ionic liquid P66614DPP (IL2) which has better performance as a lubricant, but is less biocompatible. IL1 showed excellent antiwear performance on pin-on-disc tribometer, when blended in biodegradable base stocks. The steel balls after the pin-on-disc test were analyzed using SEM-EDS technique. The oxidation stability of IL1 was studied by Pressure Differential Scanning Calorimeter (PDSC) and compared with the behavior of AP after incorporating optimized dosage of antioxidant additives in the biodegradable base stock.

Evaluation of corrosion behaviour of biodegradable base oils using electrochemical techniques

© 2015 Institute of Materials, Minerals and Mining. Published by Maney on behalf of the Institute. This paper describes an interesting attempt to quantitatively evaluate the corrosion behaviour of base oils using a novel approach based on electrochemical techniques. The present study evaluates the corrosion behaviour of biodegradable base oils with and without additives in an aqueous chloride solution using electrochemical measurements. Potentiodynamic polarisation and electrochemical impedance spectroscopy techniques were used to quantitatively determine the corrosion behaviour of these oils, and the results were compared to the conventional immersion tests. Both these electrochemical measurements were carried out in a three-electrode system where AS1020 mild steel alloy was used as a working electrode in a purpose made pipette cell. The results obtained from the electrochemical measurements help to evaluate the best biodegradable base oil for formulating eco-friendly industrial lubricants.

Prosecuting corporations and officers for industrial manslaughter-recent Australian developments

There have been concerns for some time about whether breaches of duty that cause a worker's death are appropriately dealt with under occupational health and safety legislation, or whether criminal prosecution is warranted in those cases involving recklessness or gross negligence. Defaulting employers are rarely prosecuted under existing criminal laws and there are serious doctrinal barriers to finding a corporation guilty of mens rea offences.
The Australian Capital Territory leads the way in Australia with the recent introduction of new criminal offences of industrial manslaughter for corporations and their senior officers. These laws rely on concepts of corporate liability based on organisational responsibility and corporate culture in the model Criminal Code Act 1995 (Cth) , thus avoiding the limitations of the identification doctrine. Other active Australian jurisdictions, whilst initially open to the notion of industrial manslaughter laws, have preferred to make changes to existing OHS laws to deal with the problem of workplace fatalities.
Whilst it has its limitations, and applies only in Australia's smallest jurisdiction, the Australian Capital Territory legislation reflects a commitment to treating workplace deaths with the seriousness they deserve, and making it easier to prosecute corporations whose operations are conducted recklessly or with gross negligence.

Conceptualising industrial relations in the "risk society"

This paper contrasts the characteristics of different types of modernities, noting the present transition occurring between its simple and reflexive manifestations. It then demonstrates how mainstream industrial relations theories have long been framed by a collectivist 'risk insurance principle '. In combining these two observations the argument is made that theories built around institutional dependencies that rely on the evidence or assumption ofoperable risk insurance principles and collective guardianships of workplace well being make less sense in a world of emerging personal narratives ofchoice and dependency that centre around individuals taking personal responsibility for avoiding or diminishing the risks of their engagement with uncertain labour markets. The discussion concludes by setting out the social and epistemological conditions under which future industrial relations theorising might beframed so as to accommodate these emerging conditions in a manner that is both realistic and relevant.

Intangible assets and the underpricing of industrial company initial public offerings

This study analyses 262 industrial company initial public offerings (IPOs) in Australia from 1994 to 1999. It finds that the identification and valuation of brand name, trademark, patent and capitalized research and development cost intangible assets in the prospectus significantly reduces underpricing. The identification of goodwill and license cost intangibles does not appear to be significant to underpricing. This paper supports the Beatty and Ritter (1986) argument that IPOs may display financial and nonfinancial characteristics that lower the uncertainty about the value of the lPO and hence lower the underpricing of that IPO. Our findings suggest implications for the issuer who wants to maximize the value of the firm at the time of the lPO, the underwriter who is required to guarantee the success of the capital raising and for the initial investors who are looking to reduce their uncertainty about the valuation of the lPO.

Publication bias in industrial relations research

Publication bias arises when statistically non-significant results are suppressed or when only results satisfying prior expectations are published. Like most fields, research in industrial relations is vulnerable to publication bias. In this paper qualitative and quantitative techniques are used in order to detect publication bias in the union-productivity effects literature. We find no evidence of publication bias in this literature, although there does appear to be autoregression in the published results.

Industrial relations and catholic social doctrine

This paper reviews the key principles of Catholic Social thought as they pertain to relations between labour and capital. It is argued that such principles are foundational for the conduct of ethical relations and the exercise of moral values in the workplace, and are recognisable in the right of workers to employment and just compensation for their labours, in the duty of employers to provide safe and engaging work for those in their charge, and in the obligation of the state to dispense wise governance in a manner that guarantees the welfare and security of all its citizens. It is argued that these principles have had de facto airing in Australian political and economic history, and that they might be usefully drawn upon again to protect the rights of workers under the current ascendency of neo-liberal policy solutions.

Behind WorkChoices : how one company changed Australia's industrial relations

Never has a form of legislation created such contentious and wide-reaching emotional debate in Australia. It has divided the community and has resulted in extensive media activity. To the forefront are Australian academics who have often been the resource of expert comment and their reports have been prolific. In this book, academics have taken to opportunity to write their own perception of the impact of Work Choices in the workplace.

Employment relations : integrating industrial relations and human resource management

Incorporating Human Resource Management policies within the regulatory and institutional framework that governs contemporary industrial relations has always been problematic. This paper details the nature and causes of this problem, noting the different conceptual and practical understandings that underpin each form of labour management when being applied in organisational settings. It then looks at a range of industrial relations realities confronting managers when trying to apply HRM practices, and how these practices might be accommodated within the context of such realities as a means of improving organisational effectiveness. In so doing it delineates four approaches an organisation might take in its relations with trade unions when bargaining and concluding labour contracts, and which of these are consistent and inconsistent with the coexistence of HRM and industrial relations practices. It then looks at the issue of workplace change involving trade unions and collective bargaining in terms of three categorical models—the management-driven model, the trade union gatekeeper model, and the management-union alliance model, the intention again being to show which are consistent and inconsistent with the coexistence of these different forms of labour management. The paper concludes by drawing on these conceptual models to outline the issues and policies that need to be considered when applying HRM practices within an industrial relations setting.

Differences in underpricing returns between REIT IPOs and industrial company IPOs

This paper follows Chan, Stohs, andWang (2001), which argues that the underlying value of the real estate is not by itself the reason for the very substantial differences in underpricing returns between real estate investment trust (REIT) IPOs and industrial company IPOs.We use variables identified in previous studies that have helped explain the underpricing of industrial company IPOs to help explain the underpricing of property trust IPOs. We find that the prospectus forecast dividend yield is a critical variable in the valuation and hence underpricing of REIT IPOs compared to industrial company IPOs. The sentiment towards the market and whether or not the issue is underwritten also impact the underpricing of REITs but the impact is much less than on industrial company IPOs.
