TL;DR: The results of this study suggest that horses wearing bitless bridles performed at least as well as, if not better than, those in bitted bridles, and if the use of bitting bridles does cause discomfort to horses, then theUse of bitless Bridles could be beneficial and certainly warrants further investigation.
Abstract: Throughout equitation history, bitted bridles have been the primary method of controlling the ridden horse. In response to health and behavioral concerns arising from the use of bitted bridles, bitless bridles offer new methods of steering and control. However, the effectiveness of bitless bridles on horses had not been previously examined scientifically. Therefore, the current study measured behavioral and cardiac responses of horses undergoing foundation training (bridling, long reining, and riding) wearing either a bitted or a bitless bridle. The horses wearing the bitted bridle exhibited more chewing, opening of the mouth, pawing the ground, and tail swishing than those in the bitless bridle. The horses wearing the bitless bridle exhibited more head lowering during long reining compared to those in the bitted bridle. The frequency of chewing, opening the mouth, and head raising decreased as training progressed. The number of steps taken after the application of the halt stimulus was greatest for the horses in the bitted bridle during long reining compared with those in the bitless bridle. During long reining, the heart rate and heart rate variability of the horses were higher for those in a bitted bridle compared with those in a bitless bridle. The results of this study suggest that horses wearing bitless bridles performed at least as well as, if not better than, those in bitted bridles. If the use of bitted bridles does cause discomfort to horses, as suggested by some, then the use of bitless bridles could be beneficial and certainly warrants further investigation.
TL;DR: This paper describes the development and deployment of two technologies—photoDNA and eGlyph—that are currently being used in the global fight against child exploitation and extremism.
Abstract: 593 Online platforms today are being used in deplorably diverse ways: recruiting and radicalizing terrorists; exploiting children; buying and selling illegal weapons and underage prostitutes; bullying, stalking, and trolling on social media; distributing revenge porn; stealing personal and financial data; propagating fake and hateful news; and more. Technology companies have been and continue to be frustratingly slow in responding to these real threats with real consequences. I advocate for the development and deployment of new technologies that allow for the free flow of ideas while reining in abuses. As a case study, I will describe the development and deployment of two such technologies—photoDNA and eGlyph—that are currently being used in the global fight against child exploitation and extremism.
TL;DR: The cutting and reining horse industry is growing rapidly, with enthusiasts ranging from the absentee horse owner to the full-time professional as mentioned in this paper, and it is imperative for equine practitioners to become familiar with the diagnosis and treatment options of injuries common to these horses.
Abstract: The cutting and reining horse industry is growing rapidly, with enthusiasts ranging from the absentee horse owner to the full-time professional. Owners can be involved in small local weekend shows or national events with over one million dollars in prize money. As this industry has grown, so has the competitive nature of the owners and the ability of the horses. Cutting and reining horses are primarily Quarter Horses and Paints. These horses are bred with an emphasis on small stature (14–15 hands), agility, and the mental capacity to perform under pressure. During individual events, the horses have to be under complete control while performing quick stops and high-torque turns (Figs. 1 and 2). Additionally, most of these horses begin training as late yearlings and early two-year-olds, with the goal that they will compete in fall and winter competitions as threeyear-olds. This small stature, agility, and athletic use predispose to certain stresses and injuries. Due to the increasing popularity and nationwide growth of the cutting and reining industry, it is imperative for equine practitioners to become familiar with the diagnosis and treatment options of injuries common to these horses. 2.

TL;DR: Avulsion fractures of the posteromedial eminence of the 2nd phalanx were repaired, using an ASIF cortex screw in 3 reining Quarter Horses within 9 and 11 months, respectively.
Abstract: Avulsion fractures of the posteromedial eminence of the 2nd phalanx were repaired, using an ASIF cortex screw in 3 reining Quarter Horses. Within 9 and 11 months, respectively, 2 horses were sound and back in competition as reining horses. The other horse was sound for pleasure class showing at 7 months after surgery.
