Bruising of beef costs the Australian industry at least $A36 million each year. At the Brisbane Abattoirs, drafting and weighing, followed by unloading, had the greatest potential to inflict injury to cattle. Agonistic behaviour (butting) showed a significant difference in initiation rate between horned (0.36 per animal) or hornless (0.91 per animal) cattle. Most butting occurred in the holding yards and involved the neck (47.2%) and flank (37.8%) regions more often than the hindquarters (25.0%). During unloading, drafting and weighing, cattle frequently came into heavy contact with solid objects, particularly on the back (33.1% of contacts) and upper hindquarters (25.4%). Shading behaviour differed between British and Brahman-type cattle, with 41% of British-breeds seeking shade, whereas only 6.5% of Brahman-type cattle sought shade. Problem areas in saleyards are the unloading, drafting and weighing yards, where stockhandlers and casual labourers move cattle. These workers may, by rough and abusive handling, exacerbate behaviour which leads to damage to cattle.

Abstract Background We estimated the predictive effects of ART-related perceptions on the actual ART uptake behavior among ART naïve PLWH stratified by different time of HIV diagnosis under the new strategy. Methods A prospective cohort study was conducted among ART naïve PLWH in Guangzhou, China from June 2016 to June 2017. Cox regression model was used to evaluate the predictive effects of ART-related perceptions on ART initiation among PLWH stratified by different timepoint of HIV diagnosis (i.e., before or after the update of the new treatment policy). Results Among 411 participants, 150 and 261 were diagnosed before (pre-scaleup group) and after (post-scaleup group) the implementation of the new strategy, respectively. The ART initiation rate in the post-scaleup group (88.9%) was higher than that in the pre-scaleup group (73.3%) (p < 0.001). A significant difference of mean score was detected in each HBM construct between pre- and post-scaleup groups (p < 0.05). After adjusting for significant background variables, among all participants, only the self-efficacy [adjusted HR (HRa) = 1.23, 95% CI 1.06 to 1.43, p = 0.006], has a predictive effect on ART initiation; in pre-scaleup group, all constructs of HBM-related ART perceptions were predictors of ART initiation (HRa = 0.71 to 1.83, p < 0.05), while in post-scaleup group, no significant difference was found in each construct (p > 0.05). Conclusions The ART initiation rate was high particularly among participants who diagnosed after the new treatment strategy. The important role of the time of HIV diagnosis on ART initiation identified in this study suggested that future implementation interventions may consider to modify the ART-related perceptions for HIV patients who diagnosed before the implementation of the new ART strategy, while expand the accessibility of ART service for those who diagnosed after the implementation of the new strategy.

Objectives. To observe and analyze the parameters of the sacral reflex and pudendal nerve somatosensory evoked potential (SSEP) in patients with multiple system atrophy (MSA) with respect to factors such as age, disease course, and subtype and provide evidence for the clinical diagnosis of MSA. Materials and Methods. A total of 51 MSA patients and 30 healthy controls were selected from the First Affiliated Hospital of Wenzhou Medical University from May 2013 to November 2015. Electrophysiological sacral reflex detection and SSEP detection were performed using the Keypoint EMG/EP system. The extraction rate, latency, and amplitude of the sacral reflex and SSEP in the MSA group and control group were compared. Results. The sacral reflex latency and amplitude in patients with MSA were statistically different from those of the healthy controls. The latency of sacral reflex increases with the prolongation of the disease course, and the amplitude and initiation rate decrease with the prolongation of the disease course. There was no significant difference in sacral reflex latency and amplitude between MSA patients of different ages and subtypes. There was no significant difference in the latency or amplitude of SSEP between the MSA group and healthy control group. Conclusions. The latency of sacral reflex increases with the prolongation of the disease course, and the amplitude and extraction rate decrease with the prolongation of the disease course. There was no significant difference in the parameters of sacral reflex between young MSA patients and elderly patients. And there was no statistically significant difference between MSA-P subtypes and MSA-C subtypes. This trial is registered with ISRCTNCR2009041.

AbstractMale-male agonistic behaviour of Agkistrodon contortrix was studied in the laboratory. Contests occurred during the periods of mating (Feb.-Apr. and Aug.-Oct.). Thirteen staged dyadic trials were run and larger males (mass/length ratio) were scored as winners in 11 of the 13 trials. Evidence for dominant-subordinate relationships in this species was obtained. Nine agonistic acts were coded from direct observations and from films. Seven of the acts were used in sequential analyses of intra- and inter-individual transitions. Numerous transitions were significant in both intra- and inter-individual analyses. Sequences greater than two events were detected in 3 of 4 males in the intra-individual analysis. Males that won contests exhibited certain acts significantly more frequently than males that lost, but there was no significant difference in the mean durations of like acts. Larger (mass/length ratio) males were always successful in defending a mate during courtship and in deposing smaller males from potential mates. Males introduced to pairs in copula exhibited few courtship or agonistic acts toward the pair, and in no case did introduced males depose smaller males.

Recent results in condition monitoring of machine elements by acoustic emission analysis are presented. A special method based on the evaluation of structure-borne noise emissions in the ultrasonic range is described. The ultrasound-signals caused by friction processes are captured by a broadband piezoelectric sensor and analyzed subsequently. The method has proven to be suitable for detecting the occurrence of friction between solid objects in a very reliable way. This leads to a variety of possible applications wherever occurrence of solid body friction has to be considered as an indication of failure or wear. In addition to tribometer tests, experiments with sliding bearings and slide ring seals are presented exemplarily. In both cases promising results were achieved. The significant difference of the presented method compared to other sound-based methods is in the nature of the analyzed signals: Harmonic waves of audible sounds or percussion-type stimulations are not evaluated but the portion of friction sounds emerging in the ultra-sonic range beyond audible frequencies. These friction sounds are widely unaffected by ambient noise and other sources of interference.

Four recently developed adolescent language tests, the Fullerton Test for Adolescents (FLTA), the Test of Adolescent Language (TOAL), the Clinical Evaluation of Language Functions (CELF), and the Screening Test of Adolescent Language (STAL), were compared to determine: (a) whether they measured the same language skills (content) in the same way (procedures); and (b) whether students performed similarly on each of the tests. First, respective manuals were reviewed to compare selection of subtest content areas and subtest procedures. Then, each of the tests was administered according to standardized procedures to 30 unselected sixth-grade students. Despite apparent differences in test content and procedures, there was no significant difference in students' performance on three of the four tests, and correlations among test performance were moderate to high. A comparison of the pass/fail rates for overall performance on the tests, however, revealed a significant discrepancy between the proportions of students identified in need of further evaluation on the STAL (20%) and the proportion diagnosed as language impaired on the three diagnostic tests (60-73%). Clinical implications are discussed.

The purpose of this study was to determine whether there is a statistically significant difference between the auditory selective attention abilities of normal and cerebral-palsied individuals. Twenty-three cerebral-palsied and 23 normal subjects between the ages of 5 and 21 were asked to repeat a series of 30 items consisting of from 2 to 4 digits in the presence of intermittent white noise. Results of the study indicate that cerebral-palsied individuals perform significantly poorer than normal individuals when the stimulus is accompanied by noise. Noise was not a significant factor in the performance of the normal subjects regardless of age.

Differences in real ear sound pressure levels (SPLs) with three portable stereo system (PSS) earphones (supraaural [Sony Model MDR-44], semiaural [Sony Model MDR-A15L], and insert [Sony Model MDR-E225]) were investigated. Twelve adult men served as subjects. Frequency response, high frequency average (HFA) output, peak output, peak output frequency, and overall RMS output for each PSS earphone were obtained with a probe tube microphone system (Fonix 6500 Hearing Aid Test System). Results indicated a significant difference in mean RMS outputs with nonsignificant differences in mean HFA outputs, peak outputs, and peak output frequencies among PSS earphones. Differences in mean overall RMS outputs were attributed to differences in low-frequency effects that were observed among the frequency responses of the three PSS earphones. It is suggested that one cannot assume equivalent real ear SPLs, with equivalent inputs, among different styles of PSS earphones.

Purpose School-aged children with hearing loss are best served by a multidisciplinary team of professionals. The purpose of this research was to assess school-based speech-language pathologists' (SLPs) perceptions of their access to, involvement of, and working relationships with educational audiologists in their current work setting. Method An online survey was developed and distributed to school-based SLPs in North Carolina. Results A significant difference in access to and involvement of educational audiologists across the state was found. Conclusions This research contributes to professional knowledge by providing information about current perceptions in the field about interprofessional practice in a school-based setting. Overall, SLPs reported positive feelings about their working relationship with educational audiologists and feel the workload is distributed fairly.
