The characteristics, responsibilities and future of chief information officers in the public sector

This chapter presents a model which depicts the critical factors and assists in understanding the demands and effectiveness of Chief Information Officers (CIO) in public sector organisations. The chapter explores the literature on public sector CIO addressing personal and professional characteristics. It also reviews the literature pertaining to the responsibilities and career advancement and future directions in Government departments. The authors adopt a qualitative methodology by which semi-structured interviews are conducted with CIO representatives from a State Government in Australia. From collation of the interview results, utilising a ‘mind mapping’ strategy, the chapter identifies a model that adequately reflects the critical factors required for a public sector CIO. The chapter concludes that there are certain unique characteristics and responsibilities that a public sector CIO must possess yet a private sector CIO does not require. The chapter also acknowledges the importance of outlining a future direction of the role; something which is neglected by the literature.

Production, properties and processing of American bison (Bison bison) wool grown in southern Australia

American bison grow a thick coat of fibres which assists them to withstand severe climatic conditions. Bison fibre was traditionally used in textiles by native North Americans. This study aimed to quantify the production, fibre attributes and dehairing processing of bison fibre produced from bison grazed in north-eastern Victoria. Three age/sex classes were sampled (n = 16) at seven body positions in spring. The fibre growing area was measured. Fibre was tested for diameter distribution, clean washing yield, proportion of fine fibres <36µm and fine fibre length, and processed by cashmere dehairing. Bison were 12 years of age, liveweights 160450 kg and had mean fibre growing area of 1.4 m². They produced an average 1184 g (range 5301640 g) of fine fibre with mean fibre diameter 18.5µm, clean washing yield 76.5%, wax content 9.8%, suint content 14.5%, clean fine fibre yield 56.4%, fine fibre length 37 mm and fibre curvature was 93/mm. Mid-side fibre had a crimp frequency of 6.5/cm and mean resistance to compression of 6.6 kPa. Fibre had a tenacity of 8.7 cN/tex and an extension of 39.3%. Restricted maximum likelihood mixed model analysis showed age/sex class and sampling site significantly affected all fibre attributes. Finer and longer fibre was produced in anterior sites and in younger bison. Fibre curvature declined 5.3°/mm for each 1-µm increase in mean fibre diameter. Dehaired fibre had a mean fibre diameter of 17.8 µm and mid-length of 28 mm, suitable for woollen spinning. The production by bison of coats containing significant amounts of fibre indicates that careful harvesting of fibre could form an important source of income in bison enterprises.

Visual impairment and eye care among Alaska native people

Purpose: To estimate the prevalence of visual impairment, eye disease and eye care in the Alaska Native (AN) population, by demographic and socioeconomic factors.

Methods: Population-based cross-sectional study of 3,793 AN adults aged 18–94 years enrolled in the Education and Research Towards Health (EARTH) Study from March 2004–March 2006. Data on self-reported visual impairment, cataract, glaucoma, diabetic eye disease and previous dilated eye examinations were collected using audio computer-assisted self-administered questionnaires.

Results: The unadjusted prevalence of self-reported visual impairment was 8.7% (95% confidence interval (CI): 7.9–9.7), cataract 5.9% (95% CI: 5.2–6.7), glaucoma 2.5% (95% CI: 2.0–3.0) and diabetic eye disease 1.3% (95% CI: 0.9–1.7). In all cases, age-sex adjusted prevalence estimates for the AN population were greater than available estimates for the general U.S. population. Prevalence of visual impairment and each eye disease increased with age (P < 0.01). Additional factors associated with visual impairment were education and annual household income. Overall, 70.0% (95% CI: 68.5–71.6) of participants reported a dilated eye examination within the previous two years. Dilated eye examination within the previous two years was associated with increasing age (P < 0.001). However, men and participants with lower formal education were less likely to report recent dilated eye examination. Among those with diabetes, only 67.7% (95% CI: 60.8–74.1) reported a dilated eye examination within the recommended previous one year.

Conclusions: Self-reported visual impairment, cataract, glaucoma and diabetic eye disease are prevalent in the AN population. These data may be useful in healthcare planning and education programs.

Towards a video browser for the digital native

Almost every aspect of how we create, transmit, and consume video has changed, but video interfaces still mimic those from video's inception. We extend Temporal Semantic Compression for interactive video browsing, which uses an arbitrary frame-by-frame interest measure to sub-sample video in real time, with user interface elements that visualize these measures and the effect of compressing on them. We experiment with a novel interest measure for popularity, and design novel visualizations for expressing interest measures and the compression interaction. We conduct the first formative evaluation of the TSC paradigm, with 8 subjects, and report design implications arising from it.

Elaborative relational structures in the research prose of sociology : an intercultural study

This paper investigates elaborative relational structures utilised by native English speaking and native Polish speaking scholars in sociology research articles written in English. The examined texts have been produced in American, Australian and Polish academic discourse communities. The study utilised the framework of the analysis of the rhetorical structure of tests (FARS) as an analytical tool (Golebiowski 2009, 2011). The following types of elaboration relations are discussed : amplification, extension, reformulation, explanation, instantiation and addition. Elaboration is analysed with respect to its textual function, frequency of employment, hierarchical location, recursiveness, discoursal prominence and explicitness. The elaborative systems in the examined texts are shown to be complex, with pervasive presence of multi-stage recursive structures. It is suggested that elaborativeness may be a general characteristic of the style of writing sociology, which, as a relatively new discipline, requires establishing of wide grounds for the proposed claims, where writers persuade their readers not only of the specific claims of their text, but also of frameworks of thought in which the claims are placed. It is hypothesized that the similarities in the elaborativeness across texts result from the shared stylistic conventions and traditions of the disciplinary research community of sociology, while differences in the mode of employment of elaboration relations are attributed to cultural norms and conventions as well as educational systems prevailing within the discourse communities constituting the social contexts of the studied texts.

Effects of an invasive species on refuge-site selection by native fauna : the impact of cane toads on native frogs in the Australian tropics

Invasive species can induce shifts in habitat use by native taxa: either by modifying habitat availability, or by repelling or attracting native species to the vicinity of the invader. The ongoing invasion of cane toads (Rhinella marina) through tropical Australia might affect native frogs by affecting refuge-site availability, because both frogs and toads frequently shelter by day in burrows. Our laboratory and field studies in the wet-dry tropics show that native frogs of at least three species (Litoria tornieri, Litoria nasuta and Litoria dahlii) preferentially aggregate with conspecifics, and with (some) other species of native frogs. However, the frogs rarely aggregated with cane toads either in outdoor arenas or in standardized experimental burrows that we monitored in the field. The native frogs that we tested either avoided burrows containing cane toads (or cane toad scent) or else ignored the stimulus (i.e. treated such a burrow in the same way as they did an empty burrow). Native frogs selected a highly non-random suite of burrows as diurnal retreat sites, whereas cane toads were less selective. Hence, even in the absence of toads, frogs do not use many of the burrows that are suitable for toads. The invasion of cane toads through tropical Australia is unlikely to have had a major impact on retreat-site availability for native frogs.

Comparison of genetic diversities in native and alien populations of hoary mustard (Hirschfeldia incana [L.] Lagreze-Fossat)

Increased selfing and inbreeding and, consequently, depauperate genetic diversities are commonly expected for alien colonies. We compared RAPDs data for native (southern Europe) and alien (British Isles) populations of hoary mustard (Hirschfeldia incana). This species is normally out-breeding, but it is capable of self- fertilization. Contrary to the common expectations, genetic diversities in native and alien populations were similar, without any strong evidence of decreased levels of genetic diversities in alien populations. A variety of factors may have contributed to this observation, including high variation in founding groups, founders originating from multiple H. incana source populations, and high rates of past and/or current gene flow. A review of other studies showed that this pattern of similar genetic diversities in native and alien populations was not unusual but has been regularly observed in other invasive plant species.

How do native English academic writers and Chinese native speakers writing in English promote their research

This paper reports on an investigation of a rhetorical organization of Applied Linguistics abstracts produced in Anglophone and Chinese academic discourse communities and written by native English and native Chinese speaking scholars. The study utilises the Framework for the Analysis of the Rhetorical Structure of Texts (FARS), proposed by Golebiowski (2009, 2011). FARS provides a functional account of the relational structure of texts in terms of strategies employed by writers to achieve their communicative purposes. I show how the two groups of abstracts utilize different relational schemata in order to indicate the functional prominence of textual propositions. It is proposed that relational choices, which result in differences in the accentuation of communicative messages in the two groups of abstracts, are dictated by cultural traditions and conventions underlying the discourse community into which the authors have been socialized.

Genome sequence of Ensifer sp. TW10, a Tephrosia wallichii (Biyani) microsymbiont native to the Indian Thar Desert

Ensifer sp. TW10 is novel N2-fixingbacterium isolated from a root nodule of the perennial legume Tephrosia wallichii Graham (known locally as Biyani) found in the Great Indian (or Thar) desert, a large arid regionin the northwestern part of the Indian subcontinent. Strain TW10 is a Gram-negative, rod shaped,aerobic, motile, non-spore forming, species of root nodule bacteria (RNB) that promiscuously nodulates legumes in Thar Desert alkaline soil. It is fast growing, acid-producing, and tolerates up to 2% NaCl and capable of growth at 40C. In this report we describe for the first time the primary features of this Thar Desert soil saprophyte together with genome sequence informationand annotation. The 6,802,256 bp genome has a GC content of 62% and is arranged into 57 scaffolds containing 6,470 protein-coding genes, 73 RNA genes and asingle rRNA operon. This genome is one of 100 RNB genomes sequenced as part of the DOE Joint Genome Institute 2010 Genomic Encyclopedia for Bacteria and Archaea-Root Nodule Bacteria (GEBA-RNB) project.
