A historian in the museum: Story spaces and Australia's sporting past

The last decade of the 20th century and the first decade of the new millennium were very significant in Australian sport as many of the major sports celebrated their centenaries and sesquicentenaries. A wide range of celebrations were testament to Morris-Suzuki's view that 'our visions of history are drawn from diverse sources',1 and de Groot's assessment that investigating popular culture provides insights into the ways in which the past is sold, presented, transmitted and experienced.2 Historians, like me, were involved in these events, most commonly contributing to written commissioned histories of sporting organisations. In essence we crossed the divide between history as produced within the academic discipline and those recognised by Jordanova as of a different genre—public history3 —by contributing to 'the overlapping sites where history is produced, notably outside of academia'.4 One prominent dimension of the celebrations, and the focal point of this essay, was the travelling museum displays on Cricket, Rugby League and Surf Lifesaving.5 Museum exhibitions like the sporting displays, as cross-cultural research has indicated, are important forms of public history as they are accessible, popular and considered trustworthy representations of the past.6 In recognition of the value of museums as public history and out of a sense of obligation to these sporting organisations, I attended several of these museum displays as they travelled around Australian major cities and smaller towns. What was evident during my attendances was the desire to compare and contrast the relationship between how museum displays and historians represent the past in the present. I recognised the obvious similarities as both were dealing with comparable content material, but the overwhelming sense was the differences between how museums represent the past and what historians produce in written histories. In this essay, I look to explain some of the similarities and differences between representations of Australia's sporting past in museum exhibitions and written histories.
Medicinal cannabis.

A number of therapeutic uses of cannabis and its derivatives have been postulated from preclinical investigations. Possible clinical indications include spasticity and pain in multiple sclerosis, cancer-associated nausea and vomiting, cancer pain and HIV neuropathy. However, evidence is limited, may reflect subjective rather than objective outcomes, and is not conclusive. Controversies lie in how to produce, supply and administer cannabinoid products. Introduction of cannabinoids therapeutically should be supported by a regulatory and educational framework that minimises the risk of harm to patients and the community. The Regulator of Medicinal Cannabis Bill 2014 is under consideration in Australia to address this. Nabiximols is the only cannabinoid on the Australian Register of Therapeutic Goods at present, although cannabidiol has been recommended for inclusion in Schedule 4.
Bandwidth Enhancement of a Microstrip Line-Fed Printed Wide-Slot Antenna With a Parasitic Center Patch

A printed wide-slot antenna with a parasitic patch for bandwidth enhancement is proposed and experimentally investigated. A simple 50-Ω microstrip line is used to excite the slot. A rotated square slot resonator is considered as reference geometry. The rotated square slot antenna exhibits two resonances (f1 : lower resonant frequency, f2: higher resonant frequency). By embedding a parasitic patch into the center of the rotated square slot, the lower resonant frequency is decreased and the higher resonant frequency is increased. Thus, broadband characteristic of the wide-slot antenna is achieved. The measured results demonstrate that this structure exhibits a wide impedance bandwidth, which is over 80% for |S11| ≤ -10 dB ranging from 2.23 to 5.35 GHz. Also, a stable and omnidirectional radiation pattern is observed within the operating bandwidth. In this design, a smaller ground plane is considered compared to the reference antenna (rotated square slot antenna without the parasitic center patch).
Inhibition of lens opacification during the early stages of cataract formation.

PURPOSE
To characterize the time period during cataract formation in which administration of pantethine inhibits lens cell opacification in the selenite model for cataract.


METHODS
Pantethine was administered to neonatal rat pups at selected time points from -0.5 to 17 hours with respect to injection of selenite at time = 0. The injection dose of pantethine was 820 mg/kg (1.5 mmol/kg) diluted in water at 410 mg/ml concentration. The injection dose of selenite was 3.28 mg/kg (19 mumol/kg) diluted in saline at 1.8 mg/ml concentration. Opacification was observed using a slit lamp microscope at selected time points over a 14-day period. Cataracts were staged using a classification of opacity from 0 (normal) to 6 (mature).


RESULTS
The effect of pantethine was characterized by three different time periods: administration -0.5 to 6 hours with respect to selenite injection provided highly significant protection, P < 0.001; administration 8 hours after selenite provided significant protection, P < 0.005; administration 10 to 17 hours after selenite was not protective.


CONCLUSIONS
The metabolite pantethine inhibited lens opacification during cataract formation in the selenite model. Even when pantethine was injected several hours after the administration of selenite, opacification was inhibited. Advanced stages of opacification were unresponsive to the administration of pantethine. The inhibitory effect of pantethine was statistically significant when administered during the earliest stage of opacification in the selenite model for cataract.
Grip strength ratio: a grip strength measurement that correlates well with DASH score in different hand/wrist conditions

BACKGROUND
Grip strength correlates with personal factors such as gender, age and nutritional status and has a good inter-rater reliability. It reflects fairly well how much people can use their hands.The Disabilities of the Arm, Shoulder and Hand (DASH) Outcome Measure 3 is a 30-item, self-report, questionnaire that reflects the patients' opinion on their disability due to upper-limb disorders. We assessed if grip strength and grip strength ratio correlate with DASH score.


METHODS
In 3 groups (20 healthy volunteers, 17 patients after distal radius fractures, 12 patients with different hand/wrist conditions) grip strength and DASH scores (items 1-21, 22-30 and total) were assessed. To exclude personal factors grip strengths in the injured or non-dominant hand and grip strength ratios (grip strength in the injured or non-dominant hand divided by grip strength in the non-injured or dominant hand) were assessed too. Results were analyzed groups using Pearson Correlation Coefficients and with a multivariate ANOVA.


RESULTS
Grip strength ratio was 0.97 in healthy volunteers, 0.52 in patients after distal radius fracture and 0.74 in patients with various other hand/wrist disorders.Significant correlations were found between the grip strength ratio and DASH as well as DASH subsections in all groups and between DASH scores and grip strength in some. The correlations between the ratio of the grip strength (GSR) and DASH were much stronger than the correlation between grip strength and DASH. This emphasizes the value of the GSR. Age showed no correlation with grip strength ratio using a multivariate ANOVA.


CONCLUSION
Grip strength ratio correlates well with the DASH score in different hand and wrist conditions. It is a valuable tool to assess patients that speak a different language and have problems with the non-dominant hand and probably easier to follow over time than the DASH score, which is time consuming to fill in and process.
Shortening a survey and using alternative forms of prenotification: Impact on response rate and quality

BACKGROUND
Evidence suggests that survey response rates are decreasing and that the level of survey response can be influenced by questionnaire length and the use of pre-notification. The goal of the present investigation was determine the effect of questionnaire length and pre-notification type (letter vs. postcard) on measures of survey quality, including response rates, response times (days to return the survey), and item nonresponse.


METHODS
In July 2008, the authors randomized 900 residents of Olmsted County, Minnesota aged 25-65 years to one of two versions of the Talley Bowel Disease Questionnaire, a survey designed to assess the prevalence of functional gastrointestinal disorders (FGID). One version was two pages long and the other 4 pages. Using a 2 x 2 factorial design, respondents were randomized to survey length and one of two pre-notification types, letter or postcard; 780 residents ultimately received a survey, after excluding those who had moved outside the county or passed away.


RESULTS
Overall, the response rates (RR) did not vary by length of survey (RR = 44.6% for the 2-page survey and 48.4% for the 4-page) or pre-notification type (RR = 46.3% for the letter and 46.8% for the postcard). Differences in response rates by questionnaire length were seen among younger adults who were more likely to respond to the 4-page than the 2-page questionnaire (RR = 39.0% compared to 21.8% for individuals in their 20s and RR = 49.0% compared to 32.3% for those in their 30s). There were no differences across conditions with respect to item non-response or time (days after mailing) to survey response.


CONCLUSION
This study suggests that the shortest survey does not necessarily provide the best option for increased response rates and survey quality. Pre-notification type (letter or postcard) did not impact response rate suggesting that postcards may be more beneficial due to the lower associated costs of this method of contact.
Therapeutic efficacy and safety of oral tranexamic acid and that of tranexamic acid local infiltration with microinjections in patients with melasma: a comparative study.

BACKGROUND
Tranexamic acid (TXA) has been used orally, intravenously, topically and intradermally (microinjection, microneedling) for treating melasma. However, the comparative efficacy of these different routes of administration remains underevaluated.


AIM
To ascertain the comparative efficacy of different routes of administration of TXA.


METHODS
In total, 100 consecutive patients with melasma (8 men, 92 women, age range 18-55 years) were randomly assigned to one of two groups comprising 50 patients each. Group A (3 men, 47 women) received oral TXA 250 mg twice daily, while group B (5 men, 45 women) received intradermal microinjections of TXA 4 mg/mL every 4 weeks. The treatment continued for 12 weeks in both groups. Percentage reduction in baseline Melasma Area and Severity Index (MASI) was assessed at 4-week intervals, and response was scored as very good (> 75% reduction), good (50% to < 75% reduction), moderate (25% to < 50% reduction), mild (< 25% reduction) or no response.


RESULTS
The study was completed by 39 patients in group A and 41 patients in group B. Very good response was seen in 25 and 32 patients in groups A and B, respectively, while good response was seen in 14 and 9 patients, respectively. Both treatment methods were equally effective, with an average reduction of MASI at 12 weeks of 77.96 ± 9.39 in group A and 79.00 ± 9.64 in group B. The main adverse effects were mild epigastric discomfort, hypomenorrhea, headache and injection site pain, which did not warrant discontinuation of treatment. Two patients in group A had relapses at 24 weeks.


CONCLUSION
TXA appears to be an effective and safe treatment for melasma, irrespective of its route of administration.
Clifford convolution and pattern matching on vector fields

The goal of this paper is to define a convolution operation which transfers image processing and pattern matching to vector fields from flow visualization. For this, a multiplication of vectors is necessary. Clifford algebra provides such a multiplication of vectors. We define a Clifford convolution on vector fields with uniform grids. The Clifford convolution works with multivector filter masks. Scalar and vector masks can be easily converted to multivector fields. So, filter masks from image processing on scalar fields can be applied as well as vector and scalar masks. Furthermore, a method for pattern matching with Clifford convolution on vector fields is described. The method is independent of the direction of the structures. This provides an automatic approach to feature detection. The features can be visualized using any known method like glyphs, isosurfaces or streamlines. The features are defined by filter masks instead of analytical properties and thus the approach is more intuitive.
Dynamic Effective Resistances and Approximate Schur Complement on Separable Graphs

We consider the problem of dynamically maintaining (approximate) all-pairs effective resistances in separable graphs, which are those that admit an n-separator theorem for some c < 1. We give a fully dynamic algorithm that maintains (1 + ε)-approximations of the allpairs effective resistances of an n-vertex graph G undergoing edge insertions and deletions with Õ( √ n/ε) worst-case update time and Õ( √ n/ε) worst-case query time, if G is guaranteed to be √ n-separable (i.e., it is taken from a class satisfying a √ n-separator theorem) and its separator can be computed in Õ(n) time. Our algorithm is built upon a dynamic algorithm for maintaining approximate Schur complement that approximately preserves pairwise effective resistances among a set of terminals for separable graphs, which might be of independent interest. We complement our result by proving that for any two fixed vertices s and t, no incremental or decremental algorithm can maintain the s − t effective resistance for √n-separable graphs with worst-case update time O(n) and query time O(n) for any δ > 0, unless the Online Matrix Vector Multiplication (OMv) conjecture is false. We further show that for general graphs, no incremental or decremental algorithm can maintain the s− t effective resistance problem with worst-case update time O(n) and querytime O(n) for any δ > 0, unless the OMv conjecture is false.

hat is augmented reality? An AR system supplements the real world with virtual (computer-generated) objects that appear to coexist in the same space as the real world. While many researchers broaden the definition of AR beyond this vision, we define an AR system to have the following properties: I combines real and virtual objects in a real environment; I runs interactively, and in real time; and I registers (aligns) real and virtual objects with each other. Note that we don't restrict this definition of AR to particular display technologies, such as a head-mounted display (HMD). Nor do we limit it to our sense of sight. AR can potentially apply to all senses, including hearing, touch, and smell. Certain AR applications also require removing real objects from the perceived environment, in addition to adding virtual objects. For example, an AR visualization of a building that stood at a certain location might remove the building that exists there today. Some researchers call the task of removing real objects mediated or diminished reality, but we consider it a subset of AR. Milgram 1 defined a continuum of real-to-virtual environments , in which AR is one part of the general area of mixed reality (Figure 1). In both augmented virtuality, in which real objects are added to virtual ones, and virtual environments (or virtual reality), the surrounding environment is virtual, while in AR the surrounding environment is real. We focus on AR and don't cover augmented virtuality or virtual environments. The beginnings of AR, as we define it, date back to Sutherland's work in the 1960s, which used a see-through HMD to present 3D graphics. 2 However, only over the past decade has there been enough work to refer to AR as a research field. In 1997, Azuma published a survey 3 that defined the field, described many problems, and summarized the developments up to that point. Since then, AR's growth and progress have been remarkable. In the late 1990s, several conferences on AR began, including the International Workshop and Symposium on Augmented Reality, the International Symposium on Mixed Reality, and the Designing Augmented Reality Environments workshop. Some well-funded organizations formed that focused on AR, notably the Mixed Reality Systems Lab in Japan and the Arvika consortium in Germany. A software toolkit (the ARToolkit) for rapidly building AR applications is now freely available at http://cause of the wealth of new developments, this field needs …
A randomized trial of the effectiveness of topical "ABH Gel" (Ativan(®), Benadryl(®), Haldol(®)) vs. placebo in cancer patients with nausea.

CONTEXT
The topical gel known as "ABH gel," comprising lorazepam (Ativan(®)), diphenhydramine (Benadryl(®)), and haloperidol (Haldol(®)), is frequently used to treat nausea because of its perceived efficacy, relatively low cost, and ease of use in the home setting. There are limited scientific data on this medication, however. Recent pilot studies showed no absorption of the active ingredients of the gel, prompting further prospective studies into the cause of the perceived efficacy in the clinical setting.


OBJECTIVES
To determine any difference in the effectiveness of ABH gel compared with placebo in cancer patients with nausea.


METHODS
A randomized, double-blind, placebo-controlled, crossover, noninferiority clinical trial was developed to test the hypothesis that there is no difference in the effectiveness of ABH gel compared with placebo in cancer patients with nausea. The primary outcome was the difference in nausea score (on a 0-10 scale) at baseline and at 60 minutes in each treatment group. The difference in the ABH gel-treated group compared with placebo was evaluated for noninferiority. Secondary outcomes included the number of vomiting episodes and side effects over time.


RESULTS
The mean change in nausea score from baseline to 60 minutes after treatment in the ABH gel group was 1.7 ± 2.05 and 0.9 ± 2.45 for the placebo group (P = 0.42). The placebo group was found to be noninferior to the ABH gel group in reducing the nausea score. ABH gel also did not decrease vomiting events better than placebo (P = 0.34). Only one patient reported any side effects from the treatments in either arm of the study.


CONCLUSION
ABH gel in its current formulation should not be used in cancer patients experiencing nausea.
Cooking with Semantics

We are interested in the automatic interpretation of how-to instructions, such as cooking recipes, into semantic representations that can facilitate sophisticated question answering. Recent work has shown impressive results on semantic parsing of instructions with minimal supervision, but such techniques cannot handle much of the situated and ambiguous language used in instructions found on the web. In this paper, we suggest how to extend such methods using a model of pragmatics, based on a rich representation of world state.

Obstacle detection with ultrasonic sensors and signal analysis metrics

One of the basic tasks for autonomous flight with aerial vehicles (drones) is the detection of obstacles within its flight environment. As the technology develops and becomes more robust, drones will become part of the toolkit to aid maintenance repair and operation (MRO) and ground personnel at airports. Currently laser technology is the primary means for obstacle detection as it provides high resolution and long range. The high intensity laser beam can result in temporary blindness for pilots when the beam targets the windscreen of aircraft on the ground or on final approach within the vicinity of the airport. An alternative is ultrasonic sensor technology, but this suffers from poor angular resolution. In this paper we present a solution using time-of-flight (TOF) data from ultrasonic sensors. This system uses a single commercial 40 kHz combined transmitter/ receiver which returns the distance to the nearest obstacle in its field of view, +/30 degrees given the speed of sound in air at ambient temperature. Two sonar receivers located either side of the transmitter / receiver are mounted on a horizontal rotating shaft. Rotation of this shaft allows for separate sonar observations at regular intervals which cover the field of view of the transmitter / receiver. To reduce the sampling frequency an envelope detector is used prior to the analogue-digital-conversion for each of the sonar channels. A scalar Kalman filter for each channel reduces the effects of signal noise by providing real time filtering (Drongelen, 2017a). Four signal metrics are used to determine the location of the obstacle in the sensors field of view: 1. Maximum (Peak) frequency 2. Cross correlation of raw data and PSD 3. Power Spectral Density 4. Energy Spectral Density Results obtained in an actual indoor environment are presented to support the validity of the proposed algorithm. © 2017 The Authors. Published by Elsevier Ltd.

Liquid-claim production , risk management , and bank capital structure : Why high leverage is optimal for banks

Liquidity production is a central function of banks. High leverage is optimal for banks in a model that has just enough frictions for banks to have a meaningful role in liquid-claim production. The model has a market premium for (socially valuable) safe/liquid debt, but no taxes or other traditional motives to lever up. Because only safe debt commands a liquidity premium, banks with risky assets use risk management to maximize their capacity to include such debt in the capital structure. The model can explain why banks have higher leverage than most operating firms, why risk management is central to banks' operating policies, why bank leverage increased over the last 150 years or so, and why leverage limits for regulated banks impede their ability to compete with unregulated shadow banks. & 2014 Published by Elsevier B.V.
