Sir George Simpson : 19th century fur trade governor and precursor of systematic management

Purpose – Sir George Simpson, the Governor of the Hudson's Bay Company (HBC) from 1821 to his death in 1860, was the subject of numerous biographical works that described various facets of the man including his managerial abilities, literary prowess, physical stamina, abundant energy, extensive art collection and ethnological specimens. Two related aspects of his outstanding management style have been overlooked: the genesis of his management style and where it can be placed in the evolution of management practices during the 19th century.

Design/methodology/approach – Primary data from the Hudson's Bay Company archives plus secondary sources.

Findings – Simpson's management abilities came from his grammar school education and his apprenticeship to a counting house. More importantly, it can be attributed to his association with his mentor Andrew Wedderburn, his dedication to the HBC, and his high level of physical and intellectual energy. His information intensive management style was also a significant precursor to systematic management, which occurred later in the 19th century.

Research limitations/implications – Future research should examine other examples of the evolution of management during the 19th century, particularly the transition from sub-unit accountability to systematic management.

Originality/value – The paper emphasizes the importance of managers in making management systems work.

Women, minorities, and proportional representation in Parliament : a proposal for voting reform

The right to vote permits the voices of the electorate to be heard in democracies. However, voting is often insufficient for minorities to obtain representation by their preferred candidates. For traditional political ‘minorities’ including women, self-representation is essential to political equality and social equity. Despite holding roughly 50% of the electoral vote in Australia for 100 years, women comprise only 22% of the Commonwealth Members and 29% of Senators. This paper proposes a new vote counting system, STV with Borda elimination or STV-B. STV-B retains proportional representation but much greater voter control over selection of candidates. STV-B would provide women with a mechanism that yields proportional representation for women without undermining party representation.

Diversions

The article provides information on the misconceptions in solving perimeter, area, volume and mass and on their respective interventions. Solving the perimeter of a rectangle of a lesser area through multiplication using its formula but may double the sum of its length and width to get its answer. Working out for the area of an irregular figure or a loop is solved by counting the unit-squares contained in the loop.

150 years of democracy? The case of New South Wales

New South Wales has a rich history of parliamentary democracy. As the oldest of the Australian States, it has provided a microcosm of the evolution of modern British-style democracy from the ‘hustings’ of the early colonial to the harbour views of the contemporary politicians’ offices. New South Wales’ political history is also rich with experimentation. The early introduction of the secret ballot, payment for members, the abolition of plural voting, and adult suffrage are well known. Although it needs to be recognized that it followed slightly behind that ‘ Paradise of Dissent’ South Australia on all those features.

Equally fascinating is the role of the Labour Party, whose campaigning on behalf of adult suffrage and payment for Members is fairly well known. Less known, but of great interest, were its activities on behalf of electoral reform, political accountability and easier enrolment and voting, particularly for ‘ itinerants’ at a time when its political base was in the rural workforce. New South Wales Labour was significant for its decision to stand alone, in contrast with its Victorian and New Zealand counterparts, which threw in their lot with the Progressives.

The potential use of otoliths for pilchard stock discrimination

Pilchards were collected from south-eastern Australian waters and aged by counting growth rings on their ear bones (otoliths). Differences in growth and population age structures were compared between regions. The shape characteristics of the ear bones were also examined using rapid, objective, semi-automated methods. Differences between the areas were shown.

Dielectrophoretic-activated cell sorter based on curved microelectrodes

This article presents the numerical and experimental analysis of a dielectrophoretic-activated cell sorter (DACS), which is equipped with curved microelectrodes. Curved microelectrodes offer unique advantages, since they create strong dielectrophoretic (DEP) forces over the tips and maintain it over a large portion of their structure, as predicted by simulations. The performance of the system is assessed using yeast (Saccharomyces cerevisiae) cells as model organisms. The separation of the live and dead cells is demonstrated at different medium conductivities of 0.001 and 0.14 S/m, and the sorting performance was assessed using a second array of microelectrodes patterned downstream the microchannel. Further, microscopic cell counting analysis reveals that a single pass through the system yields a separating efficiency of ~80% at low medium conductivities and ~85% at high medium conductivities.

Textural fractography of fatigue failures under variable cycle loading

A new concept of counting time at fatigue processes is proposed, aimed to reach fractographic compatibility in cases of different loading sequences. Values of cycle effectivity are summarized to give the new reference time. The improvement is shown in application - textural fractography of three specimens loaded by constant cycle, constant cycle with periodic overloading, and a random block, respectively. In contrast to the conventional crack growth rate, the reference crack growth rate is related to common morphologic features of all fracture surfaces.

Towards a southern theory of higher education

Crudely, social inclusion in Australian higher education is a numbers game. While the student recruitment departments of universities focus on ‘bums on seats’, equity advocates draw attention to ‘which bums’, in ‘what proportions’, and, more to the point, ‘which seats’, ‘where’. But if the counting of bums is crude, so is the differentiation of seats. Just distinguishing between courses and universities and scrutinizing the distribution of groups, is a limited view of equity. The most prestigious seats of learning give students access primarily to dominant forms of knowledge and ways of thinking. In terms of access, it is to a diminished higher education, for all. Further, undergraduates – particularly in their first year – are rarely credited with having much to contribute. Higher education is the poorer for it. In this paper I propose an expanded conception for social inclusion and an enlarged regard for what is being accessed by students who gain entry to university. Drawing on Connell’s conception of ‘Southern Theory’, I highlight power/knowledge relations in higher education and particularly ‘southerners’: those under‐represented in universities – often located south of ENTER (Equivalent National Tertiary Entrance Rank) cut‐offs – and whose cultural capital is similarly marginalised and discounted. While increasing regard for the importance of Indigenous knowledges is beginning to challenge the norms of higher education, we are yet to generalise such reconceptions of epistemology to include knowledges particular to people from regional and rural areas, with disabilities, and from low socioeconomic backgrounds. Nor have we really engaged with different ways of thinking about the physical and social worlds that are particular to these groups. To take account of marginalized forms of knowledge and of thinking will mean thinking differently about what higher education is and how it gets done.

Copper levels in buccal cells of vineyard workers engaged in various activities

Objectives: Copper-based compounds have been used as agricultural fungicides for many years. Their use in Australia is escalating with increase in the scale of planting and associated pest problems. The objective of this study was to identify viticulture activities associated with high exposure to foliage sprays. It would be determined if occupational exposure of vineyard workers to copper-based sprays was associated with raised body copper levels through analysis of saliva and buccal cells.

Methods: The activities of six vineyard workers from four vineyards in the Yarra Valley Victoria, Australia, were monitored over a period of 2 years. During this period, workers carried out seasonal activities, including fungicide spraying, canopy management, and tractor operation. Saliva and buccal cells from workers were collected and analysed for copper levels that were then correlated with the different types of vineyard activity.

Results: The buccal cells of vineyard workers exposed to copper through seasonal activities including fungicide spraying, canopy management, and tractor operation contained copper levels of 0.87, 1.24, and 0.95 ng Cu per 106 cells, respectively. This was up to 10-fold higher than the copper levels in buccal cells from the control subjects (0.1 ng Cu per 106). Copper levels in buccal cells from workers participating in other viticulture activities such as shoot thinning, bunch counting, and disbudding were not significantly different from those of control subjects. The levels of copper in saliva samples of both workers undertaking any vineyard activity and control subjects were below the level of detection.

Conclusions: Seasonal activities undertaken in vineyards that involved direct contact with copper, in particular canopy management, fungicidal spraying, and tractor operation were associated with high copper levels in buccal cells of workers. This indicates that copper derived from copper-based fungicidal compounds is accumulated within body cells. The lack of detectable copper levels in saliva suggests that the route of transport of copper into buccal cells is not through saliva. The results indicate potential adverse health risks associated with use of copper fungicide. Recommendations are made in relation to the precautions that should be taken in relation to use of copper sprays and to validate buccal cells as an indicator of body copper status.

Towards a southern theory of student equity in Australian higher education : enlarging the rationale for expansion

Student equity in Australian higher education is a numbers game. While university student recruitment departments focus on ‘bums on seats’, equity advocates draw attention to which bums, in what proportions and, more to the point, which seats, where. But if the counting of ‘bums’ is crude, so is the differentiation of seats. Just distinguishing between courses and universities and scrutinizing the distribution of groups is a limited view of equity. This paper proposes an expanded conception for student equity and an enlarged regard for what is being accessed by students who gain entry to university. Drawing on Connell’s notion of ‘southern theory’, the paper highlights power/knowledge relations in higher education and particularly for ‘southerners’: those under-represented in universities, often located south of cut-off scores, and whose cultural capital is similarly marginalised and discounted. The paper concludes that taking account of marginalized forms of knowledge requires thinking differently about what higher education is and how it gets done.

Linguistic and psychometric validation of the diabetes-specific quality-of-life scale in U. K. english for adults with type 1 diabetes

OBJECTIVE To develop a linguistically and psychometrically validated U.K. English (U.K./Ireland) version of the Diabetes-Specific Quality-of-Life Scale (DSQOLS) for adults with type 1 diabetes.

RESEARCH DESIGN AND METHODS We conducted independent forward and backward translation of the validated German DSQOLS. An iterative interview study with health professionals (n = 3) and adults with type 1 diabetes (n = 8) established linguistic validity. The DSQOLS was included in three Dose Adjustment for Normal Eating (DAFNE) studies (total N = 1,071). Exploratory factor analysis (EFA) was undertaken to examine questionnaire structure. Concurrent and discriminant validity, internal consistency, and reliability were assessed.

RESULTS EFA indicated a six-factor structure for the DSQOLS (social aspects, fear of hypoglycemia, dietary restrictions, physical complaints, anxiety about the future, and daily hassles). High internal consistency reliability was found for these factors and the weighted treatment satisfaction scale (α = 0.85–0.94). All subscales were moderately, positively correlated with the Audit of Diabetes-Dependent Quality-of-Life (ADDQoL) measure, demonstrating evidence of concurrent validity. Lower DSQOLS subscale scores [indicating impaired quality of life (QoL)] were associated with the presence of diabetes-related complications.

CONCLUSIONS The DSQOLS captures the impact of detailed aspects of modern type 1 diabetes management (e.g., carbohydrate counting and flexible insulin dose adjustment) that are now routine in many parts of the U.K. and Ireland. The U.K. English version of the DSQOLS offers a valuable tool for assessing the impact of treatment approaches on QoL in adults with type 1 diabetes.

Critical evaluation of the nursery role hypothesis for seagrass meadows

The vast majority of published papers concerning seagrass meadows contain statements to the effect that seagrass beds serve as important nurseries for many species. We reviewed more than 200 papers that were relevant to the nursery role hypothesis. We used both vote counting and meta-analytic techniques to evaluate whether the body of previous studies that report seagrass meadows to be nursery grounds actually contain data that support this proposition. We restricted our analyses to papers that compared seagrass beds to other habitats, and examined data on a variety of well-studied species concerning their density, growth, survival and migration to adult habitat. Within this group of papers, we considered potential factors that could influence the nursery function (e.g. location, or laboratory vs field studies). We also evaluated case histories of well-documented large-scale seagrass losses on the nursery function. Major results were consistent with the expectations that abundance, growth and survival were greater in seagrass than in unstructured habitats. Abundance data also suggested that seagrass beds in the Northern Hemisphere might be more important as nursery areas than those in the Southern Hemisphere. Surprisingly, few significant differences existed in abundance, growth or survival when seagrass meadows were compared to other structured habitats, such as oyster or cobble reefs, or macroalgal beds. Nor were there decreases in harvests of commercially important species that could clearly be attributed to significant seagrass declines in 3 well-studied areas. However, there were decreased abundances of juveniles of commercially important species in these areas, suggesting a strong link between seagrass abundance and those of juvenile finfish and shellfish. One important implication of these results is that structure per se, rather than the type of structure, appears to be an important determinant of nursery value. Clearly, more rigorous studies that test all aspects of the nursery role hypothesis are clearly needed for seagrass meadows as well as other structured habitats. The results of such studies will allow better decisions to be made concerning the conservation and restoration of marine habitats.

Wave of bombings across Iraq ahead of elections

The people of Iraq have also endured bombings but on a larger scale. There are media reports saying up to thirty-one people were killed in dozens of separate explosions across different Iraqi provinces including two blasts at a checkpoint at Baghdad international airport.

This comes just days before provincial elections across Iraq, the first ballot since the withdrawal of US troops at the end of 2011. Although it is unclear who carried out the attacks different factions are increasingly stoking the fire as they vie for political power in the upcoming elections. Tawar Razaghi spoke to Senior Research Fellow, Dr Benjamin Isakhan, at the Centre for Citizenship and Globalisation at Deakin University.
