Repeated sprint training improves intermittent peak running speed in team-sport athletes. J Strength Cond Res 25(5): 1318-1325, 2011-The aim of this study was to compare the effect of 2 repeated sprint training interventions on an intermittent peak running speed (IPRS) test designed for Australian Rules football. The test required participants to perform 10 3 10-m maximal efforts on an 80-m course every 25 seconds, for each of which the mean peak speed (kilometers per hour) was recorded to determine IPRS. The training interventions were performed twice weekly for 4 weeks immediately before regular football training. In the constant volume intervention (CVol), sprint repetition number remained at 10 (n = 9), and in the linear increase in volume (LIVol) intervention, repetition number increased linearly each week by 2 repetitions (n = 12). Intermittent peak running speed, 300-m shuttle test performance, and peak running speed were assessed before and upon completion of training. All measures were compared to a control group (CON; n = 8) in which players completed regular football training exclusively. Intermittent peak running speed performance in CVol and LIVol improved significantly (p < 0.01) by 5.2 and 3.8%, respectively, with no change in IPRS for CON. There were no differences in IPRS changes between CVol and LIVol. Additionally, peak running speed improved significantly (p < 0.01) by 5.1% for CVol, whereas 300-m shuttle performance improved significantly (p < 0.01) by 2.6% for LIVol only. Intermittent peak running speed, 300-m shuttle performance and peak running speed were improved after 4 weeks of training; however, progressively increasing sprint repetition number had no greater advantage on IPRS adaptation. Additionally, exclusive regular football training over a 4-week period is unlikely to improve IPRS, peak running speed, or 300-m shuttle performance.

In the last few decades social networking sites have encountered their first large-scale security issues. The high number of users associated with the presence of sensitive data (personal or professional) is certainly an unprecedented opportunity for malicious activities. As a result, one observes that malicious users are progressively turning their attention from traditional e-mail to online social networks to carry out their attacks. Moreover, it is now observed that attacks are not only performed by individual profiles, but that on a larger scale, a set of profiles can act in coordination in making such attacks. The latter are referred to as malicious social campaigns. In this paper, we present a novel approach that combines authorship attribution techniques with a behavioural analysis for detecting and characterizing social campaigns. The proposed approach is performed in three steps: first, suspicious profiles are identified from a behavioural analysis; second, connections between suspicious profiles are retrieved using a combination of authorship attribution and temporal similarity; third, a clustering algorithm is performed to identify and characterise the suspicious campaigns obtained. We provide a real-life application of the methodology on a sample of 1,000 suspicious Twitter profiles tracked over a period of forty days. Our results show that a large set of suspicious profiles behaves in coordination (70%) and propagates mainly, but not only, trustworthy URLs on the online social network. Among the three largest detected campaigns, we have highlighted that one represents an important security issue for the platform by promoting a significant set of malicious URLs. Copyright 2013 ACM.

This study examines the annual reports of the top 20 software and information technology companies listed on the Australian Stock Exchange, using the content analysis method. The findings of this study indicate that the levels of Intellectual capital disclosures are found to be low and are reported in qualitative form rather than quantitative form. The results of the study highlight that software and information technology companies in Australia do not attach importance to disclosing voluntary intellectual capital information. This study emphasises the need for an established and generally accepted framework for the reporting of intellectual capital to enable measurability and presentation of intellectual capital information in the annual reports.

BACKGROUND: To identify and prioritise targets for injury prevention efforts, injury incidence studies are widely reported. The accuracy and consistency in calculation and reporting of injury incidence is crucial. Many individuals experience more than one injury but multiple injuries are not consistently reported in sport injury incidence studies. OBJECTIVE: The aim of this systematic review was to evaluate current practice of how multiple injuries within individuals have been defined and reported in prospective, long-term, injury studies in team ball sports. DATA SOURCES: A systematic search of three online databases for articles published before 2016. STUDY SELECTION: Publications were included if (1) they collected prospective data on musculoskeletal injuries in individual participants; (2) the study duration was >1 consecutive calendar year/season; and (3) individuals were the unit of analysis. DATA EXTRACTION: Key study features were summarised, including definitions of injury, how multiple individual injuries were reported and results relating to multiple injuries. RESULTS: Of the 71 publications included, half did not specifically indicate multiple individual injuries; those that did were largely limited to reporting recurrent injuries. Eight studies reported the number/proportion of athletes with more than one injury, and 11 studies presented the mean/number of injuries per athlete. CONCLUSIONS: Despite it being relatively common to collect data on individuals across more than one season, the reporting of multiple injuries within individuals is much more limited. Ultimately, better addressing of multiple injuries will improve the accuracy of injury incidence studies and enable more precise targeting and monitoring of the effectiveness of preventive interventions.

Reporting on training developed for pharmacy assistants and pharmacy dispensary technicians working with Medication Assisted Treatment for Opioid Dependence (MATOD) consumers in regional Victoria
Description:
A recent study (Patil et al., 2018) analysing lived experiences of Medication Assisted Treatment for Opioid Dependence (MATOD) consumers suggested that some experienced discrimination and stigma in the pharmacy context in regional Victoria, Australia. One of the recommendations was to explore professional training and education opportunities for allied health professionals and in particular, Pharmacy Assistants (PAs) and Pharmacy Dispensary Technicians (PDTs) as they are integral to serving MATOD consumers. Ballarat Community Health commissioned Federation University to develop training modules for PAs and PDTs working in the pharmacy settings in regional Victoria. A survey of the literature identified two key issues, namely, the lack of professional education and training of PAs and PDTs involved in serving the consumers in pharmacy settings either at the national or state level in Australia. The other finding was the varied use of different types of ‘opioid dependence’ treatments in different jurisdictions of Australia which had implications in terms of embedding psychosocial or Social Determinants of Health (SDH) with therapeutic treatments. As a result, this project serves as a significant step in employing SDH based training modules for PAs and PDTs working with MATOD consumers in the pharmacy settings to address stigma and discrimination. The training workshop materials will be evaluated to determine its efficacy in terms of change of attitudes and professional practice. The aim of this study is to: 1. Deliver and evaluate a new professional training module concerning MATOD and; 2. Examine and evaluate the efficacy and impact of the training module on professional practice and changes in attitudes towards stigma and discrimination amongst PAs and PDTs. This project was conducted in two stages. At the first stage, two workshops (each lasting for two hours) were delivered in two different regional locations in the state of Victoria, Australia (referred to as locations A and B in this report). Thirteen participants expressed interest in location A but eleven attended both training workshops. In location B, fourteen attended the first workshop, while twelve attended the second workshop. Participants who attended the training were administered pre-training and post-training surveys. The pre-training surveys included demographic information, professional experience, educational background and professional training, whereas the post-training survey involved questions about the impact and efficacy of the training delivered. The second stage involved conducting in-depth qualitative interviews with participants who attended the training workshops. The main goal was to evaluate the impact on professional practice and change in attitudes amongst PAs and PDTs. Data collected from the surveys and interviews were analysed using quantitative and qualitative content analysis via an inductive process. In addition, an interpretive phenomenological analysis was undertaken to identify and code themes emerging from the interviews. Ethics approval was received through the Federation University’s Human Research Ethics Committee before the commencement of this project.

Description:
Core Ideas The heterogeneity of soil hydraulic properties can be described with effective parameters. Increasing model complexity can be used to represent plot‐scale soil heterogeneity. One‐dimensional dual‐domain flow models are used to reproduce 2D preferential transport. Local subscale variability effects are included as mass transfer in an effective model. Agricultural soils are characterized by a structure that is strongly dependent on farming practices like tillage and trafficking. These practices can create compacted zones in the soil, thus initiating preferential flow. Two‐ or three‐dimensional models can be used to account for the spatial variability of the soil hydraulic and transport properties. Since it is challenging to obtain such data, it is logical to find simpler approaches. Our objective was to design a one‐dimensional (1D) modeling approach that effectively accounts for plot‐scale soil structure variability. A 1D dual‐permeability model was tested in which compacted soil was represented by a matrix domain and uncompacted soil by a fracture domain and eventually by assuming an additional immobile water region (MIM) in the fracture domain representing compacted clods embedded within the uncompacted soil. Models (1D) were compared with two‐dimensional single‐porosity (2D_SP) modeling results for water flow and Br− transport based on a previously performed field tracer experiment. Results indicated good agreement between 1D dual‐domain approaches (1D_DPERM and 1D_DPERM_MIM) and the 2D_SP representative model simulation results with high model efficiency and with respect to the field observations. This implied that a 1D vertical model description was sufficient to represent plot‐scale variability if smaller scale soil structure heterogeneities could be accounted for as effective parameters in dual‐domain models. Variation in the mass transfer term had a large effect on the vertical Br− profile distribution. The parameters describing the sizes and shapes of the domains were most relevant for estimating mass transfer between soil structural features in heterogeneous agricultural fields. Still, the calibration of the upscaling approach of two‐domain interactions in larger scale models remains challenging.

Description:
The Big Strike of 1919-20 was Broken Hill’s greatest industrial battle but the photographic record of this militant era on the Barrier mines is dominated by pictures of the Great 1909 Lockout. Rather than cover the details of these well-known disputes, this article considers the value and power of photographs of the disputes – their presence, absence, production and presentation in major newspapers and in postcards – an area which has secured far less attention from Australian labour historians. Our concern is not only to read this visual material as evidence of industrial disputes but also to consider how the widespread circulation of such images affected contemporary perceptions of The Hill. We argue that images of a militant locality with a determined labour movement, popular after the 1909 dispute, may well have attracted militant organisers to the town who were important players in the major 1919-20 Big Strike. These images have dominated perceptions of Broken Hill as a bastion of unionism ever since
Description:
The ordered order-k Voronoi diagram is a popular generalization of the ordinary Voronoi diagram modeling ordered k nearest sites. Despite of the usefulness of the ordered order-k Voronoi diagram, its structural complexity and wealth of information captured result in poor readability. Most research has focused on computational complexity, and visualization/representation of the ordered order-k Voronoi diagram has received little attention. This paper attempts to represent the ordered order-k Voronoi diagram through its relationship with other higher order Voronoi diagrams. The proposed method highlights topo-logical relationships between/among higher order Voronoi diagram families, and enhances the readability of the ordered order-k diagram.
Description:
This article examines the proposed popular historical interpretation of the decommissioned Pentridge Prison, in the course of its redevelopment as a residential and commercial precinct. The interpretation is judged to have been 'appropriated' by a 'gatekeeper' group comprising former prison officers in partnership with the commercially motivated site owners. In the process, it is argued, a wide range of 'alternative' narratives are excluded from the prison's public history. Examples of such narrative options are presented, including that of the author, who identifies as a stakeholder in the interpretation of the prison. This narrative 'sampling' is done with a view to asking how the consequent broader interpretation can be conveyed to visitors to the site. 'The eternal questions that concern historians … are the ones with which we grapple endlessly. Whose history is being told? Whose history is left out? Whose collective memory should be celebrated? Whose is forgotten? Which past should be preserved? Which re-created?'

In June of 2015 during a stay in Berlin we visited, on successive days, the Stasi Museum and the Stasi Prison, in former East Berlin. The Stasi Prison operated as a remand and interrogation facility continually from immediately after World War II until the fall of the Berlin Wall and the dismantling of the communist regime in East Germany. Virtually all of the many thousands of citizens who populated the Prison during those four decades were political prisoners, and as such the representation of their experience in the site provides important insights into the nature of the regime and its impact on daily life. The Stasi Museum is in the former headquarters of the East German Ministry for State Security in the Berlin suburb of Lichtenberg, and provides a highly engaging representation of the Ministry’s history, bureaucratic structure and activities (see Stasi Museum 2016). It also furnished us with valuable social and historical background for visiting the Stasi Prison the following day. The account we give in this chapter, however, focuses entirely on our experience of the Prison. The tour we did there was guided by a German national but was conducted in English.
Description:
The purpose of the present study was to examine the reproducibility of laboratory-based 40-km cycle time-trial performance on a stationary wind-trainer. Each week, for three consecutive weeks, and on different days, forty-three highly trained male cyclists (x̄ ± SD; age = 25 ± 6 y; mass = 75 ± 7 kg; peak oxygen uptake [V̇O 2peak] = 64.8 ± 5.2 ml x kg-1 x min-1) performed: 1) a V̇O2peak test, and 2) a 40-km time-trial on their own racing bicycle mounted to a stationary wind-trainer (Cateye - Cyclosimulator). Data from all tests were compared using a one-way analysis of variance. Performance on the second and third 40-km time-trials were highly related (r=0.96; p < 0.001), not significantly different (57:21 ± 2: 57 vs. 57:12 ± 3:14 min:s), and displayed a low coefficient of variation (CV)=0.9 ± 0.7%. Although the first 40-km time-trial (58:43 ± 3: 17 min:s) was not significantly different from the second and third tests (p = 0.06), inclusion of the first test in the assessment of reliability increased within-subject CV to 3.0 ± 2.9%. 40-km time-trial speed (km x h -1) was significantly (p < 0.001) related to peak power output (W; r = 0.75), V̇O2peak (1 x min-1; r = 0.53), and the second ventilatory turnpoint (1 x min-1; r = 0.68) measured during the progressive exercise tests. These data demonstrate that the assessment of 40-km cycle time-trial performance in well-trained endurance cyclists on a stationary wind-trainer is reproducible, provided the athletes perform a familiarization trial.
Description:
The timing of breeding and habitat preference in the stubble quail (Coturnix pectoralis) were assessed at two study sites, Dookie and Mitiamo, in the north of Victoria. Surveying was over and eight month period between September 1993 - April 1994. Reproductive timing was determined by monitoring changes in the gomad size of shot birds. Breeding events were verified by disproportionate increases in the number of young birds shot. Population density was measured as an indicator of habitat preference. Site characteristics known to affect habitat selection were monitored. Breeding was in spring and autumn. Spring breeding coincided with the period of maximum plant growth. Autumn breeding was stimulated by above average late summer rainfall. Male stubble quail were shot in greater numbers during a known breeding event. Stubble quail preferred areas of lightly grazed pasture dominanted by native grass species. Recently harvested wheat and barley stubble provided an abundant short-term food supply, however the ability of this habitat type to support resident stubble quail populations is questioned. Stubble quail population density appeared to be strongly influenced by territorial behaviour during breeding. Implications for the management of this game species are discussed and future lines of research recommended.
