Surviving financial distress : the case of too many herbs and spices

Over 120 years ago Sir James Burns founded an organisation that is today, the international business group of Burns Philp and Company Ltd. The Group is widely known as a leading producer of yeast products and manufacturer of other bakery ingredients. Its ability to adapt to the ever-changing demands of business is widely recognised. During the late 1980’s however, after the group expanded into the herbs and spices industry its financial state deteriorated. Yet, arguably the Group had entered a market that complimented its then existing core-activities. This paper examines circumstances surrounding that venture into herbs and spices. It argues that the Group’s financial predicament, at that time, was exacerbated by the use of conventional accounting procedures. It illustrates that up-to-date market related financial details, in lieu of accounting book constructs, more aptly assist directors, managers, all stakeholders to conduct business and make informed economic decisions. This paper suggests that it is an entity’s current financial state of affairs, with regard to tangible market referents, that enables a firm’s strategic progress and facilitates proactive management; and in turn, assists in the sustainable development of business throughout the world.

Dietary counseling to increase natural folate intake: a ransomized placebo-controlled trial in free-living subjects to assess effects on serum folate and plasma total homocysteine.

BACKGROUND: The association between vascular disease and elevated plasma total homocysteine (tHcy) concentrations is caused, in part, by inadequate intakes of dietary folate. Increasing folate intake either through supplements or foods naturally rich in folates has been shown to decrease tHcy concentrations. OBJECTIVE: The aim of this study was to determine whether a similar reduction in tHcy was possible in free-living persons receiving dietary counseling. DESIGN: The study included a 4-wk placebo-controlled dietary intervention trial in which participants consumed either unfortified breakfast cereal (control group) or an extra 350 micro g folate derived from food/d (dietary group). Serum folate and tHcy concentrations in both groups were measured before and after the intervention period, and the concentrations in the dietary group were also measured 17 wk after the intervention period. RESULTS: During the 4-wk intervention, mean dietary folate intake in the dietary group increased from 263 (95% CI: 225, 307) to 618 micro g/d (535, 714), resulting in a mean increase in serum folate of 37% (15%, 63%) and a decrease in tHcy from 12.0 (10.9, 13.3) to 11.3 micro mol/L (10.2, 12.5). A further decrease in tHcy occurred in the dietary group during follow-up, with a final tHcy concentration of 9.7 micro mol/L (8.8, 10.8). CONCLUSIONS: Increasing natural folate intake improved folate status and decreased tHcy concentrations to an extent that may significantly reduce the risk of vascular disease. Dietary modification may have advantages over folic acid fortification because the altered food-consumption patterns lead to increased intakes of several vitamins and minerals and decreased intakes of saturated fatty acids.

What can Hannah Arendt's theorising add to equity policy activism in higher education institutions?

Human rights theory is based on universalistic moral perspectives that regard each individual as a bearer of rights. These rights are often legislated nationally and implementation mandated for institutions including higher education institutions. Arendt contests this kind of governance and ruling. Arendt argues for an agonal politics. Arendt theorises politics and power as something that cannot occur in isolation; it is through ‘acting in concert’ with others that a political community is constituted. Arendt advocates for a public space where people can take care of the ‘public things’ between them to work out how to live together. In this paper I reflect on my role promoting equity within Australian higher education institutions and explore what Arendt’s theorising can add to rethinking this kind of human rights work. Arendt argued that re-valuing politics would pave the way to a ‘new appreciation of human plurality’ (Villa 1996: 17). I will argue that the ‘Fair Chance for All’ (1990) equity policy promoted a form of identity politics within higher education institutions. I argue that Arendt’s theorising can effectively disrupt identity politics and offers a corrective to the way human rights legislation and related institutional policies tend to focus on specific target populations.

Just out of reach : access to equity in Australian higher education

This paper provides an account of access and equity in Australian higher education across the period of recent Federal Labor governments and specifically of the discourses and practices surrounding A Fair Chance For All: Higher Education That's Within Everyone's Reach, Labor's latest policy on equal access to Australian higher education. The paper positions such an account within Australia's changing national and global economic condition, and the influence of New Right ideologies that proffer efficient and effective public sector management practices and market freedoms that have witnessed a privatisation and peeling back of the welfare state. The paper argues that while Federal Labor has clearly established social justice on the agenda of Australian higher education, it is a justice mediated by particular economic and managerial practices which tend to limit equity to issues of access and place broader equity concerns for higher education just out of reach.

Predicting future earnings growth: a test of the dividend payout ratio in the Australian market

This paper examines the use of the payout ratio as a predictor of a firm’s future earnings growth. Recent evidence rejects the hypothesis that firm which retain a large portion of their earnings have strong future earnings growth. Higher dividend payout ratios instead correspond to higher future earnings growth. Examining both listed and delisted firms on the Australian stock exchange over the period 1989 to 2008, we provide further evidence that the dividend payout ratio is positively linked to future earnings growth. The results hold over both one, three and five year periods. Furthermore, our results rejected claims that such a relationship was caused by simple mean reversion in earnings. We find no evidence to support the cash flow signaling and free cash flow hypotheses as an explanation for this relationship.

An application of the Element Free Galerkin Method to the analysis of quantum well structures

In order to obtain the quantum-mechanical properties of layered semicondutor structures (quantum well and superlattice structures, for instance), solutions of the Schrodinger equation should be obtained for arbitrary potential profiles. In this paper, it is shown that such problems may be also studied by the Element Free Galerkin Method.

From anionic polymerization in continuous flow to macromolecular architectures and stimuli-responsive surfaces

The thesis can be divided in four parts and summarized as follows:(i) The investigation and development of a continuous flow synthesis procedure affording end-functional polymers by anionic polymerization and subsequent termination in one reaction step and on a multigram scale was carried out. Furthermore, the implementation of not only a single hydroxyl but multiple orthogonal functionalities at the chain terminus was achieved by utilizing individually designed, functional epoxide-based end-capping reagents.(ii) In an additional step, the respective polymers were used as macroinitiators to prepare in-chain functionalized block copolymers and star polymers bearing intriguing novel structural and material properties. Thus, the second part of this thesis presents the utilization of end-functional polymers as precursors for the synthesis of amphiphilic complex and in some cases unprecedented macromolecular architectures, such as miktoarm star polymers based on poly(vinyl pyridine), poly(vinyl ferrocene) and PEO.(iii) Based on these structures, the third part of this thesis represents a detailed investigation of the preparation of stimuli-responsive ultrathin polymer films, using amphiphilic junction point-reactive block copolymers. The single functionality at the block interface can be employed as anchor group for the covalent attachment on surfaces. Furthermore, the change of surface properties was studied by applying different external stimuli.(iv) An additional topic related to the oxyanionic polymerizations carried out in the context of this thesis was the investigation of viscoelastic properties of different hyperbranched polyethers, inspired by the recent and intense research activities in the field of biomedical applications of multi-functional hyperbranched materials.
