Nobody Wants to Eat Them Alive:” Ethical Dilemmas and Dual Media Narratives on Domestic Rabbits as Pets and Commodity

Using semiotic analysis, this study explores changes occurring in the societal perception of rabbits as farm animals as juxtaposed to their increasing popularity as domestic companions. This study is based on a preliminary hypothesis that rabbits are increasingly perceived and portrayed in media as domestic companion animals similar to cats and guinea pigs, which challenges a parallel narrative that views rabbits as commodities for their meat and fur. Operating within a theoretical framework that considers news media as both socially constructed reality and recorded history, the study examines the dynamics of change in numbers of coded news narratives drawn as a 1000-piece convenience sample from a database of news stories published worldwide between 1990 and 2011

The Eddy Experiment: accurate GNSS-R ocean altimetry from low altitude aircraft

During the Eddy Experiment, two synchronous GPS receivers were flown at 1 km altitude to collect L1 signals and their reflections from the sea surface for assessment of altimetric precision and accuracy. Wind speed (U10) was around 10 m/s, and SWH up to 2 m. A geophysical parametric waveform model was used for retracking and estimation of the lapse between the direct and reflected signals with a 1-second precision of 3 m. The lapse was used to estimate the SSH along the track using a differential model. The RMS error of the 20 km averaged GNSS-R absolute altimetric solution with respect to Jason-1 SSH and a GPS buoy measurement was of 10 cm, with a 2 cm mean difference. Multipath and retracking parameter sensitivity due to the low altitude are suspected to have degraded accuracy. This result provides an important milestone on the road to a GNSS-R mesoscale altimetry space mission.Comment: All Starlab authors have contributed significantly; the Starlab Author list has been ordered randoml

Solar cell radiation response near the interface of different atomic number materials

The response of cobalt 60 irradiated N/P silicon solar cells was measured as a function of the atomic number of the medium adjacent to the cell and the direction of the gamma ray beam. The interpositioning of various thicknesses of aluminum between the adjacent material and the cell had the effect of moving the cell to various locations in an approximate monatomic numbered medium. Using this technique the solar cell response was determined at various distances from the interface for gold and beryllium. The results were compared with predictions based upon ionization chamber measurements of dose perturbations in aluminum and found to agree within five percent. Ionization chamber data was then used to estimate the influence of various base contact materials

The use of ultrasonic fat measurements of 8mm and 10mm as a marketing guide for feeder heifers

One hundred eighty feeder heifers (150 Herford, 29 Angus, and one crossbred) of Choice, Good, and Medium feeder grades were fed to a final back fat thickness of Smm or 10mm using ultrasonics as the marketing guide. Heifers were purchased at graded feeder calf sales in East Tennessee. After an adjustment period of three weeks, the heifers were fed corn silage ad libitum, treated at the time of ensiling with 10 pounds each of urea and ground limestone plus six pounds of concentrate per head per day, for 110 days, and then full fed a concentrate ration of eight parts ground shelled corn to one part 41 percent cottonseed meal, to finish the heifers at an ultrasonically estimated back fat thickness of 8mm or 10mm. Heifers that were slaughtered when the ultrasonically estimated fat thickness reached 8mm produced carcasses comparable to those of heifers slaughtered at 10mm fat thickness. No significant (P \u3c .05) differences were found between the two fat levels in carcass grade, yield grade, and percent retail yield. The heifers fed to 5mm subcutaneous fat finished 10 days earlier than the 10mm level heifers, and cost per hundred weight gain overall was in favor of the 5mm level heifers by $0.88. Average return over initial invest-ment and feed cost was in favor of the 5mm heifers by$0.75. Results of this experiment indicate that the use of ultrasonics does not penalize either feedlot performance or carcass characteristics, and that using ultrasonics reduces significantly the time the feeder cattle were in the feedlot. Also, that marketing at 8mm fat thickness is just as profitable as marketing at 10mm and shortened the feedlot period by 10 days

Multi-scale Orderless Pooling of Deep Convolutional Activation Features

Deep convolutional neural networks (CNN) have shown their promise as a universal representation for recognition. However, global CNN activations lack geometric invariance, which limits their robustness for classification and matching of highly variable scenes. To improve the invariance of CNN activations without degrading their discriminative power, this paper presents a simple but effective scheme called multi-scale orderless pooling (MOP-CNN). This scheme extracts CNN activations for local patches at multiple scale levels, performs orderless VLAD pooling of these activations at each level separately, and concatenates the result. The resulting MOP-CNN representation can be used as a generic feature for either supervised or unsupervised recognition tasks, from image classification to instance-level retrieval; it consistently outperforms global CNN activations without requiring any joint training of prediction layers for a particular target dataset. In absolute terms, it achieves state-of-the-art results on the challenging SUN397 and MIT Indoor Scenes classification datasets, and competitive results on ILSVRC2012/2013 classification and INRIA Holidays retrieval datasets

Proof Theory, Transformations, and Logic Programming for Debugging Security Protocols

We define a sequent calculus to formally specify, simulate, debug and verify security protocols. In our sequents we distinguish between the current knowledge of principals and the current global state of the session. Hereby, we can describe the operational semantics of principals and of an intruder in a simple and modular way. Furthermore, using proof theoretic tools like the analysis of permutability of rules, we are able to find efficient proof strategies that we prove complete for special classes of security protocols including Needham-Schroeder. Based on the results of this preliminary analysis, we have implemented a Prolog meta-interpreter which allows for rapid prototyping and for checking safety properties of security protocols, and we have applied it for finding error traces and proving correctness of practical examples

A study of blood contamination of Siqveland matrix bands

AIMS To use a sensitive forensic test to measure blood contamination of used Siqveland matrix bands following routine cleaning and sterilisation procedures in general dental practice. MATERIALS AND METHODS: Sixteen general dental practices in the West of Scotland participated. Details of instrument cleaning procedures were recorded for each practice. A total of 133 Siqveland matrix bands were recovered following cleaning and sterilisation and were examined for residual blood contamination by the Kastle-Meyer test, a well-recognised forensic technique. RESULTS: Ultrasonic baths were used for the cleaning of 62 (47%) bands and retainers and the remainder (53%) were hand scrubbed prior to autoclaving. Overall, 21% of the matrix bands and 19% of the retainers gave a positive Kastle-Meyer test, indicative of residual blood contamination, following cleaning and sterilisation. In relation to cleaning method, 34% of hand-scrubbed bands and 32% of hand-scrubbed retainers were positive for residual blood by the Kastle-Meyer test compared with 6% and 3% respectively of ultrasonically cleaned bands and retainers (P less than 0.001). CONCLUSIONS: If Siqveland matrix bands are re-processed in the assembled state, then adequate pre-sterilisation cleaning cannot be achieved reliably. Ultrasonic baths are significantly more effective than hand cleaning for these items of equipment
