Mentoring in the leading across effective small schools program : the perspectives of 'critical friends'

In this chapter, I refer to the reflections of Wendy Graham and Carolyn Scott who were ‘critical friends’ or mentors working alongside school leaders in the Leading across Effective Small Schools (LAESS) program. As recently retired principals of small rural schools, the mentors offered support, encouragement and advice to LAESS participants in order to enhance collegial cross-school improvement and develop leadership skills. These perspectives provide another important dimension to this book, because a mentor or critical friend can be more objective and see the bigger picture more clearly. Mentors are removed from day-today school life, yet importantly these mentors have ‘insider’ or situated knowledge about small rural school contexts and leadership which assists current school leaders to reflect on their practice and grow as leaders. The chapter also draws on comments from mentors, which emerged in independent formal evaluations of the LAESS program conducted by Carol Oakley.

Generic medicines in Australia : business dynamics and recent policy reform

This article describes the role of generics in the Australian prescription drug market and patterns of business activity in this dynamic market segment. The Pharmaceutical Benefits Scheme (PBS) is the central mechanism for the supply of prescription medicines. PBS prices are arrived at through cost-effectiveness analyses comparing new products against already available products and therapies. In this system, prices do not operate effectively as incentives for consumers or prescribers to choose generics, and their market share was historically marginal. In recent years, generics suppliers achieved a growing market share through discounts (trading terms) to pharmacists. It is estimated that around 30% of PBS scripts, representing around 15% of PBS sales by value, are now filled with generics. Complex changes to the PBS were introduced in 2007, to be phased in over the period to 2012, aimed at increasing the scope for cost benefits to the government, and to lesser extent consumers, from the expanding availability of generic medicines.

Personal property securities (draft ) bill 2008 - problems and why it will not work

Attempts are under way to condense more than 70 pieces of federal, state and territory legislation on personal property securities (PPS) into a single Federal Act. The revised second draft of the PPS Bill 2008 was released in November calling for further public comments by December 2008. The aim of this article is to highlight some of the important instances where further intensive drafting is needed. It draws out some key issues that have not been addressed that may assist in further revising the bill. Overall, the author firmly believes that the bill is far from perfect, that much work is still needed to improve clarity and readability and to minimise any uncertainty in the use of certain terms that are repetitive and obsolete. The article concludes with some useful references that Australia could perhaps learn from the problems currently experienced in New Zealand under its own PPS Act.

The trading dynamics of close-substitute futures markets : evidence of margin policy spillover effects

Volatility spillover is well documented among closely related securities. I investigate the relationship between margin policy and trading dynamics of the Nikkei 225 index futures markets of Osaka Securities Exchange (OSE) and Singapore Exchange (SGX). I find that OSE’s margin policy influences trading dynamics across both markets, although it is the less liquid SGX market that performs price discovery. This suggests that policy markers of close substitute markets should coordinate, or at least communicate policy intentions due to policy spillover. SGX’s market design facilitates price discovery, suggesting that a microstructure framework capable of overcoming the liquidity entry barrier is of interest to any futures exchange contemplating contract proliferation.

Floor trading and screen trading : distinctions for practitioners

The creation of an electronic limit order book is discussed as the basis for distinguishing between the floor trading and screen trading of derivative instruments. Distinguishing between FTP and ETP in terms of market transparency allows investors to contemplate the trade-off between the 2 platforms. Distinguishing between FTP and ETP in terms of memory preservation allows practitioners to contemplate the different experiences when analyzing floor data and screen data. A comparable set of floor and screen data is used to examine the impact on the trading dynamics and price discovery of LIFFE's FTSE 100 index futures market when trading is automated on LIFFE CONNECT. The dynamics in the quote change equation is shortened when moving from the floor to screen sample. Using the model's measure of trade informativeness, it is found that in 4 out of 5 daily sub-samples, screen trades are more than twice as informative as floor trades. Variability within a system of equations is explained more by order size history than trade size history.

Momentum profits in Australian listed property trusts

This paper examines the profitability of momentum trading strategies in Australian listed property trusts (LPTs). Monthly value-weighted momentum portfolios are formed using the monthly excess returns of LPTs for the period from 1990 to 2005. Overall the findings confirm that a momentum trading strategy in Australian LPTs is a profitable strategy. More specifically, momentum strategies are profitable after adjusting for variance and downside risk where the momentum returns substantially outperform the benchmark. An analysis using different study periods confirm the findings about momentum. The practical implication from this study is that investors can generate substantial abnormal returns by adopting a momentum trading strategy, particularly with a long strategy (i.e. winner portfolios).

The impact of globalisation on building surveying in Europe

This research examined the impact of globalisation on building surveying in Europe. Globalisation has resulted in the emergence of three large trading blocs or a global economy depending on the view one takes. This has impacted on property in two ways, by creating transnational companies who operate in many countries but require branding of their property, and companies who wish to invest in property markets other than their country of origin.

Building Surveyors have professional expertise and knowledge valued in the UK since the 1960 and 1970s but until recently not recognised in Europe, partly due to poor awareness of Building Surveying (BS) expertise, legal constraints, and practises relating to the employment of professionals. This is changing with the establishment of European Surveying associations and the globalisation of the RICS.

The results showed four factors provided the reasons for the globalisation of BS skills. These were that Building Surveyors provided a consistent level of service for their clients. Secondly that English is the language of business. Thirdly, clients perceive Europe as a single trading bloc with a need for technical representation in each investment centre, providing them with a fast, knowledgeable service. Fourthly, clients perceive that UK Building Surveyors know what international, or transnational, investors want.

The finding on the current demand for the BS services in Europe is that though demand is large, few Building Surveyors are located in Europe. Secondly, both investors and occupiers require the services of Building Surveyors, and local companies / individuals are beginning to use their professional services. Finally, there is a diverse range of demand for the many BS skills.

Five key barriers to the practice of BS skills in Europe emerged from the research. Firstly, there was the problem of limited local legal and technical knowledge possessed by outsiders. Secondly, there are legal barriers to practice in some cases. Thirdly, other professionals can, and do, offer the services of the Building Surveyor. Fourthly, there can be cultural differences between ‘values’ and ‘norms’ required in business that constitute barriers. Finally there can be ‘communication’ problems when the Building Surveyor is not located in the country where the service is required.

Entrepreneurship in Mexico : lessons for stakeholders in New Zealand

A “neighbour” separated by 6,000 km of Pacific, Mexico is by far New Zealand’s largest trading partner in Latin America and its 15th largest overall. With two-way trade worth NZ$584 million in 2002, many Mexicans grow up on New Zealand milk powder and baby formula. Not only is Mexico’s population of 100 million a huge potential economic partner in its own right, through its network of free trade agreements, Mexico has preferential access to 860 million consumers in 32 countries covering sixty percent of the world’s GDP.

Like New Zealand, Mexico is a “New World” country open to new ideas and innovation. Also like New Zealand, Mexico is known internationally for economic reforms that have created two outward-looking, world-trading, and competitive economies. During the last 50 years, the Mexican economy has shifted away from the once dominant sectors of agriculture and mining toward more industrial activities, especially in the major urban centres of Mexico City, Monterrey, Guadalajara, and other regional centres, where entrepreneurs are concentrated. With this shift, a new class of entrepreneurs arose with the support of the government.

One of those regional centres is the State of Sinaloa, with its capital city, Culiacán. Spearheaded by a visionary government and personified by the Secretary of Economic Development, Heriberto Felix Guerra. Secretary Felix is himself restaurant entrepreneur who owns a growing chain of “concept food” restaurants in the region.

It is no accident that when New Zealand Prime Minister Helen Clark visited Mexican President Vicente Fox Quesada on 15 November 2001, one of the topics of conversation was the fact that very day their two countries had been benchmarked as two of the world’s most entrepreneurial countries in the Global Entrepreneurship Monitor 2001 survey.

More germane, both countries have low-aspiration entrepreneurs who generate low levels of wealth and have low potential for growth. Both are dominated by micro-businesses that do not have high-value-added components and are not investment-ready and pre-qualified for risk capita.

This leads to the question, what can New Zealanders learn from the experience of Mexican entrepreneurship?

The case for reverse mortgages in Australia : applying the USA experience

In the USA, reverse mortgages have been promoted as a means of accessing equity locked up in a residence, especially after the owner/s has retired. Although there have been some teething problems, the concept of mortgaging the family home after achieving freehold ownership has many merits. Often an asset-rich household must survive on relatively small regular income, and is unable to access the increasing wealth of the family home. A reverse mortgage overcomes this hurdle.

The largest asset for many ageing households is their primary place of residence, the traditional house and suburban land parcel. Recently, the Australian housing market has witnessed substantial growth in the value of its capital city housing, especially on the east coast of Australia. This can be attributed to factors such as owner-occupiers trading up to a better class of dwelling, and the continuing gentrification process for owners choosing not to relocate. At the same time, demographic changes have placed pressure on the regular income of retirees, many of whom have no superannuation fund. For example, life expectancy rates continue to rise and there are an increasing proportion of single person households in society. This has placed additional pressure on financial resources of retirees, especially those with a substantial investment in their family home and a relatively small pension.

This paper visits the reverse mortgage scenario in the USA and considers potential implications for the Australian market. Strengths and weaknesses of this product are contemplated, and the viability of reverse mortgages is discussed. Although there are obvious benefits for certain segments of society, reverse mortgages are a unique product and caution should be exercised to ensure the public is fully knowledgeable from the outset.

There is something about pairs trading

The process of pairs trading involves exhaustively matching and ranking pairwise stocks based on some prespecified measure of closeness; e.g., correlation, cointegration, sum-of-squared price difference. Pairs trading is popular for various reasons. It is simple to follow and execute. The pairwise portfolio can be nearly market-neutral, such that it does not require the comprehensive analysis of macroeconomic news. Since it is based on relative valuation, the actual worth of individual firms is not a pertinent consideration. The strategy is sufficiently flexible to accommodate various investment styles. Lastly, it does not evoke frequent intraday rebalancing, such that pairs trading can be automated to a certain extent and be cost-feasibly profitable. Despite its long history on Wall Street, pairs trading remains elusive in nature. The academic attention it attracts is modest compared to contrarian and momentum trading.

Economic linkages across commodity futures : hedging and trading implications

We investigate cross-market trading dynamics in futures contracts written on seemingly unrelated commodities that are consumed by a common industry. On the Tokyo Commodity Exchange, we find such evidence in natural rubber (NR), palladium (PA) and gasoline (GA) futures markets. The automobile industry is responsible for more than 50% of global demand for each of these commodities. VAR estimation reveals short-run cross-market interaction between NR and GA, and from NR to PA. Cross-market influence exerted by PA is felt in longer dynamics, with PA volatility (volume) affecting NR (GA) volume (volatility). Our findings are robust to lag-specification, volatility measure, and consistent with full BEKK-GARCH estimation results. Further analysis, which benchmarks against silver futures market, TOCOM index and TOPIX transportation index, confirms that our results are driven by a common industry exposure, and not a commodity market factor. A simple trading rule that incorporates short-run GA and long-run PA dynamics to predict NR return yields positive economic profit. Our study offers new insights into how commodity and equity markets relate at an industry level, and implications for multi-commodity hedging.

Common industry exposure in seemingly unrelated commodities

We propose and document robust evidence of cross-market return, volatility, and volume interactions among futures contracts written seemingly unrelated commodities exposed to a common industry. On the Tokyo Commodity Exchange, we find such evidence in natural rubber (NR), aluminum (AL) and gasoline (GA) futures markets, which are complementary commodities heavily consumed by Japan's automobile industry. Our VAR results indicate that (i) for shorter dynamics, NR and GA volatility both influence AL volatility; GA volume affects NR volatility and volume; the GA market is immune to both NR and AL trading activities; (ii) for longer dynamics, AL volume affects both NR volume and GA volatility; NR volume influences GA volume. These results are robust to lag-specifications, volatility measures and are consistent with full BEKK-GARCH estimates. Further analysis using the silver contract, TOCOM and TOPIX transportation indices, shows that a commodity market factor cannot explain our result. Our results offer insights into how commodity and equity markets relate at an industry level.

Regulatory and enabling approaches to corporate law enforcement : patterns of litigation 1986-2002 and the effect of recent reforms in New Zealand, Australia and the United Kingdom

Enforcement of corporate rights and duties may follow either a ‘regulatory’ or ‘enabling’ model. If a regulatory approach is taken, enforcement action will generally be undertaken by regulatory agencies such as, in New Zealand, the Registrar of Companies and Securities Commission, the Australian Securities and Investments Commission (ASIC) or the Department of Trade and Industry (DTI) in the United Kingdom. If an enabling approach is chosen, enforcement action will more often be by private parties such as company shareholders, directors or creditors. When New Zealand's company law was reformed in 1993, a primarily private enforcement regime was adopted, consisting of a list of statutory directors' duties and an enhanced collection of shareholder remedies, based in part upon North American models and including a statutory derivative action. Public enforcement was largely confined to administrative matters and the enforcement of the disclosure requirements of New Zealand's securities law. While the previous enforcement regime was similarly reliant on private action, the law on directors' duties was less accessible, and shareholder action was hindered by the majority rule principle and the rule in Foss v Harbottle. This approach is in contrast with that used in Australia and the United Kingdom, where public agencies have a much more prominent enforcement role despite recent and proposed reforms to directors' duties and shareholder remedies. These reforms are designed to improve the ability of private parties to enforce corporate rights and duties. A survey of enforcement litigation in New Zealand since 1986 indicates that the object of a primarily enabling enforcement regime seems to have been achieved, and may well have been achieved even without the 1993 reform package. Private enforcement has, in fact, been much more prevalent than public enforcement since well before the enactment of the new legislation. Most enforcement action both before and after the reform was commenced by shareholders and shareholder/directors, and most involved closely held companies. Public enforcement was largely undertaken in areas such as securities law, where the wider public interest was affected. Similar surveys of Australian and United Kingdom enforcement litigation reveal a proportionally much greater reliance on public bodies to enforce corporate rights and duties, indicating a more regulatory approach. The ASIC and DTI enforced a wider range of provisions, affecting both closely and widely held companies, than those subject to public enforcement in New Zealand. Publicly enforced provisions in Australia and the United Kingdom include directors' duties and provisions dealing with disqualification from managing companies, as well as securities law requirements.

Firms as adaptive organizations : the case of Australian trading banks

The conventional accounting notion of ‘going concern’ — that a firm will continue its business operations in the same manner indefinitely — has underpinned accounting practice for over one hundred years. This idea has provided a rationale for spreading costs over accounting periods and for deferring costs as assets in balance sheets. An alternative idea that is widely regarded as reliable in the literatures of economics and deliberate action is that firms continually adapt to changes in market and economic conditions. That is economic behaviour. The implications of that view of a firm for accounting have been systematically explored by Chambers (1966). While not examining those particular implications, many other accounting theorists have been critical of the conventional accounting idea of 'going concern' and of its impact on accounting practice. The two notions of ‘going concern’ - as static or adaptive enterprises - are examined by referring to the business operations of the four major Australian trading banks over the period 1983-1991. Banks were selected because they are commonly thought to be particularly ‘conservative’ organizations. The period 1983—1991 was chosen because it covers the era of deregulation of the Australian financial system. The evidence adduced by this study indicates that the Australian trading banks have continually adapted their organizational structures and business operations in the light of changes in technology, markets for financial services, government policies and domestic and global economic conditions. Illustrations of adaptive behaviour by banks ate drawn from their normal operating procedures such as the provision of products and services, loan services, acquisitions, sale of property, non-core banking operations and international banking. It is argued on analytical grounds that the cost basis of accounting does not yield financial statements that provide factual and up-to-date information about the financial capacity of firms to pay their debts and to continue trading generally; that is, to be going concerns. At any time, those financial capacities are determined by the amount of money commanded by a firm, including the money's worth of its assets, and by its level of debt. It is concluded on empirical grounds that the Australian trading banks, at least, are adaptive entities.

Impact of electronic data interchange in the Australian automotive industry

Information technology continues to play an increasingly significant role in the development of firms competing in the vast array of markets from those classified as global markets, such as the automotive industry, to the smaller nationally-based markets such as retailing. An objective of electronic commerce is to assist organisations to remain competitive and gain entry to markets which were previously unattainable. This study focuses on the organisational impact of one form of electronic commerce (electronic data interchange) on the component sector of the Australian automotive industry and examines the extent to which trading partner relationships have been affected. The research investigates the extent to which the integration of electronic data interchange (EDI) with an organisation’s internal application system may facilitate specific net benefits. The automotive industry became the first Australian industry to cooperatively adopt EDI. Research to date has not adequately examined the organisational impact of the nature and extent of net benefits gained from EDI adoption. To achieve the objective of assessing EDI net benefits, a conceptual model was developed. The model proposed that the level of EDI net benefits expected is influenced by the size of the organisation and the concentration of trade achieved within the industry via intervening links through (a) the level of senior management commitment and (b) the extent of system integration. Nine empirically testable research propositions are derived from the model, each testing the relationship between model constructs. Data was collected from 114 component suppliers to Ford Australia in 1992 and 1994 using a repeated cross-sectional longitudinal design. Structural equation modelling using partial least squares was adopted in the analysis of the data. A pure longitudinal model together with 12 case studies of selected component manufacturers supplemented the research design. The results of the research showed that the proposed conceptual model is a good description of the data. In particular, net benefits obtained from EDI adoption are directly determined by the size of the organisation, and the extent to which firms integrate EDI into their internal application systems. The level of net benefits is only indirectly influenced by the level of senior management commitment to the EDI project through (a) management commitment’s direct effect on integration, and (b) the direct effect the volume of trade a supplier achieves with the automotive industry on senior management commitment and system integration. The major benefits organisations experienced from EDI were enhanced productivity, clerical staff savings, improved data accuracy, enhanced customer service and reduced administration costs. The research showed that few suppliers gained inventory savings from EDI, a frequently claimed benefit from EDI adoption. Evidence of small improvements in product quality emerged from the results. In summary, this research attempts to make two primary contributions to knowledge, first in providing a method by which net benefits from electronic commerce can be measured within an industry adopting electronic trading, and second, by providing organisations with the knowledge of the specific net benefits organisations could expect from EDI adoption, together with the four major factors affecting these benefits. The research concludes with possible directions for future research, in particular an assessment of the impact of incorporating financial EDI into electronic trading.
