Strawberries any-time, any-day, any-where : a strategic marketing analysis

While the number of Australian strawberry producers has declined by 40% over the past decade the value of production has increased by 58%. Such changes reflect structural changes occurring within an increasingly competitive industry. This paper discusses a study that was conducted to develop a marketing strategy that was conducted in order to reposition an industry so that it may grow in the face of a maturing product life cycle.

To establish a benchmark position, an industry analysis based on the Five Forces model was first undertaken. This analysis was followed by a consumer analysis which consisted of (a) a series of focus group discussions and (b) a comprehensive consumer marketing research survey. The findings of this survey enabled a series of market segments to be identified and profiled. Based on these results a strategic marketing communication campaign aimed at increasing strawberry consumption was developed and implemented.

Reliability and variability of day-to-day vault training measures in artistic gymnastics

Inter-day training reliability and variability in artistic gymnastics vaulting was determined using a customised infra-red timing gate and contact mat timing system. Thirteen Australian high performance gymnasts (eight males and five females) aged 11-23 years were assessed during two consecutive days of normal training. Each gymnast completed a number of vault repetitions per daily session. Inter-day variability of vault run-up velocities (at -18 to -12 m, -12 to -6 m, -6 to -2 m, and -2 to 0 m from the nearest edge of the beat board), and board contact, pre-flight, and table contact times were determined using mixed modelling statistics to account for random (within-subject variability) and fixed effects (gender, number of subjects, number of trials). The difference in the mean (Mdiff) and Cohen's effect sizes for reliability assessment and intra-class correlation coefficients, and the coefficient of variation percentage (CV%) were calculated for variability assessment. Approach velocity (-18 to -2 m, CV = 2.4-7.8%) and board contact time (CV = 3.5%) were less variable measures when accounting for day-to-day performance differences, than pre-flight time (CV = 17.7%) and table contact time (CV = 20.5%). While pre-flight and table contact times are relevant training measures, approach velocity and board contact time are more reliable when quantifying vaulting performance.

Television viewing time of colorectal cancer survivors is associated prospectively with quality of life

Objective : To examine prospective associations of television viewing time with quality of life, following a colorectal cancer diagnosis.

Methods : One thousand, nine hundred and sixty-six colorectal cancer survivors were recruited through the Queensland Cancer Registry. Interviews were conducted at 5, 12, 24, and 36 months post-diagnosis. Generalized linear mixed models estimated the effects of television viewing time on quality of life.

Results : Participants who watched ≥5 h of television per day had a 16% lower total quality of life score than did participants reporting ≤2 h per day. Deleterious associations of television viewing time were found with all quality of life subscales: functional well-being showed the strongest association (23% difference in quality of life scores between highest and lowest television viewing categories), and social well-being the weakest association (6% difference). Participants who increased their television viewing by one category (e.g., ≤2 h, increasing to 3–4 h per day) had a proportional decrease of some 6% in their quality of life score (intra-individual effect).

Conclusions : The deleterious associations of television viewing time with quality of life were clinically significant and consistent over time. Decreasing sedentary behavior may be an important behavioral strategy to enhance the quality of life of cancer survivors.

The relationship between time of founding and the composition of the workforce in Australian workplaces

This paper presents the results of an analysis of the relationship between organisational age and two specific aspects of labour flexibility-numerical
flexibility and workforce skill composition (as one facet of functional flexibility)that extends earlier work in two ways. First, it uses data from a large-scale national survey (the Australian Workplace Industrial Relations Survey [AWIRS)1995). Second. it focuses on two widely studied facets of labour flexibility, numerical flexibility and functional flexibility. Previous research has investigated the relationship between organisational age and aspects of organisation such as strategy and structure (Baum and Oliver, 1991; Henderson, 1999; Reed and Blunsdon, 1998). Henderson (1999) found that age effects were contingent on different organisational strategies and process. Reed and Blunsdon (1998) found that organisational maturity is associated with goal directed, or strategic flexibility characterised by low levels of formal rules and regulations but clarity a/purpose. But a more complex relationship was also identified - for example; very young organisations (founded in the 1990,) appear to have higher levels of formalisation at founding than organisations established in earlier periods. This paper investigates these questions further. The results show that the relationship between age; numerical flexibility and workforce skill composition is non-linear, but the data do not make it possible to separate age effects associated with aging, time of founding and changing environmental conditions.

Spatial and temporal changes in abundance of the infaunal bivalve Soletellina alba (Lamark, 1818) during a time of drought in the seasonally-closed Hopkins River Estuary, Victoria Australia

The infaunal bivalve Soletellina alba is susceptible to mass mortalities during annual winter flooding in the Hopkins River Estuary, southern Australia. Periods of low salinity (≤1) are the likely cause of these mass mortality events, which can occur in seasonally-closed estuaries when high winter flows are sufficient to flush all salt water from the estuary. Core samples of S. alba were collected from two water depths across four times and at three sites near the mouth of the estuary. Minimal to zero abundances of large S. alba (>1 mm) were expected to be sampled, particularly at the shallower water depth, during a typical winter flood event. However, the present study occurred during a period of drought, which led to the absence of winter flooding. This absence of winter flooding prevented the occurrence of lethal salinities (i.e. ≤1) in the estuary during this period and a greater number of living S. alba adults were sampled. Abundances of juvenile and adult S. alba were still variable, even in the absence of winter flooding, and reflected an interaction between date, site and water depth. However, no mass mortalities of adults were observed during the drought conditions in contrast to what occurs during typical winter flood events and provides support for the hypothesis that winter flooding is responsible for past mass mortalities.

Optimality analysis of sensor-target geometries in passive localization: Part 2 - time-of-arrival based localization

In this paper we characterize the relative sensor-target geometry in R2 in terms of potential localization performance for time-of-arrival based localization. Our aim is to characterize those relative sensor-target geometries which minimize the relative Cramer-Rao lower bound.

It's academic : American studies in a time of crisis

My archive- the collection of resources I have drawn upon for my comments- includes, among other sources, a panel on international American studies held at the American Studies Association conference in Montreal in November 1999, the Wednesday Higher Education supplement of the Australian newspaper, and another supplement- this is one in the Derridean sense of the word- the Howard government. I hope to draw these threads together to focus on the present crisis facing American studies and, not coincidentally, this Association. To arrive at this point I take a tour through theoretical and disciplinary responses to the prevailing situation.

Conservative discourse at the time of the Korean War. 1950-52

This thesis identifies the rhetorical strategies by which the Menzies government reconciled acceptance of full employment, the welfare state and government intervention with a defence of liberalism. It argues that the Korean War offered the Menzies government an opportunity to reconstitute these key aspects of the postwar state as "liberal" rather than social democratic.

Investigation of the postcure reaction and surface energy of epoxy resins using time-of-flight secondary ion mass spectrometry and contact-angle measurements

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) was used to investigate correlations between the molecular changes and postcuring reaction on the surface of a diglycidyl ether of bisphenol A and diglycidylether of bisphenol F based epoxy resin cured with two different amine-based hardeners. The aim of this work was to present a proof of concept that ToF-SIMS has the ability to provide information regarding the reaction steps, path, and mechanism for organic reactions in general and for epoxy resin curing and postcuring reactions in particular. Contact-angle measurements were taken for the cured and postcured epoxy resins to correlate changes in the surface energy with the molecular structure of the surface. Principal components analysis (PCA) of the ToFSIMS positive spectra explained the variance in the molecular information, which was related to the resin curing and postcuring reactions with different hardeners and to the surface energy values. The first principal component captured information related to the chemical phenomena of the curing reaction path, branching, and network density based on changes in the relative ion density of the aliphatic hydrocarbon and the C₇H₇O⁺ positive ions. The second principal component captured information related to the difference in the surface energy, which was correlated to the difference in the relative intensity of the C_xH_yN_z⁺ ions of the samples. PCA of the negative spectra provided insight into the extent of consumption of the hardener molecules in the curing and postcuring reactions of both systems based on the relative ion intensity of the nitrogen-containing negative ions and showed molecular correlations with the sample surface energy.
