	Title	Development of an ethogram for a pain scoring system in ridden horses and its application to determine the presence of musculoskeletal pain			Type	Journal Article
	Year	2018	Publication	Journal of Veterinary Behavior	Abbreviated Journal
	Volume	23	Issue		Pages	47-57
	Keywords	Lameness; Equine behavior; Pain grading; Headshaking; Bucking; Rearing
	Abstract	There is evidence that more than 47% of the sports horse population in normal work may be lame, but the lameness is not recognized by owners or trainers. An alternative means of detecting pain may be recognition of behavioral changes in ridden horses. It has been demonstrated that there are differences in facial expressions in nonlame and lame horses. The purpose of this study was to develop a whole horse ethogram for ridden horses and to determine whether it could be applied repeatedly by 1 observer (repeatability study, 9 horses) and if, by application of a related pain behavior score, lame horses (n = 24) and nonlame horses (n = 13) could be differentiated. It was hypothesized that there would be some overlap in pain behavior scores among nonlame and lame horses; and that overall, nonlame horses would have a lower pain behavior score than lame horses. The ethogram was developed with 117 behavioral markers, and the horses were graded twice in random order by a trained specialist using video footage. Overall, there was a good correlation between the 2 assessments (P < 0.001; R2 = 0.91). Behavioral markers that were not consistent across the 2 assessments were omitted, reducing the ethogram to 70 markers. The modified ethogram was applied to video recordings of the nonlame horses and lame horses (ethogram evaluation). There was a strong correlation between 20 behavioral markers and the presence of lameness. The ethogram was subsequently simplified to 24 behavioral markers, by the amalgamation of similar behaviors which scored similarly and by omission of markers which showed unreliable results in relation to lameness. Following this, the maximum individual occurrence score for lame horses was 14 (out of 24 possible markers), with a median and mean score of 9 (±2 standard deviation) compared with a maximum score of 6 for nonlame horses, with a median and mean score of 2 (±1.4). For lame horses, the following behaviors occurred significantly more (P < 0.05, chi-square): ears back, mouth opening, tongue out, change in eye posture and expression, going above the bit, head tossing, tilting the head, unwillingness to go, crookedness, hurrying, changing gait spontaneously, poor quality canter, resisting, and stumbling and toe dragging. Recognition of these features as potential indicators of musculoskeletal pain may enable earlier recognition of lameness and avoidance of punishment-based training. Further research is necessary to verify this new ethogram for assessment of pain in ridden horses.

	Title	Return to Sport after Serious Injury: A Retrospective Examination of Motivation and Psychological Outcomes			Type	Journal Article
	Year	2005	Publication	Journal of Sport Rehabilitation	Abbreviated Journal	Journal of Sport Rehabilitation
	Volume	14	Issue	1	Pages	20-34
	Keywords
	Abstract	Context: It is argued in self-determination theory that the motivation underlying behavior has implications for health and well-being independent of the behavior itself. Objective: To examine associations between athlete motivations for returning to sport after injury and perceived psychological return-to-sport outcomes. Design: A correlational survey design was employed to obtain data in Canada, Australia, and England. Participants: Elite and subelite athletes (N = 180) with injuries requiring a minimum 2-month absence from sport participation. Main Outcome Measures: Participants completed an inventory measuring perceptions of motivation to return to sport from a serious injury and psychological return-to-sport outcomes. Results: Correlational analyses revealed that intrinsic motivations for returning to competition were associated with a positive renewed perspective on sport participation. Conversely, extrinsic motivations for returning to sport were associated with increased worry and concern. Conclusions: The motivation underlying return to sport might play an important role in return-to-sport perceptions among elite and subelite athletes.

	Title	Reputational Effectiveness in Cross-Functional Working Relationships			Type	Journal Article
	Year	2004	Publication	Journal of Product Innovation Management	Abbreviated Journal	‎J. Prod. Innov. Manag.
	Volume	21	Issue	1	Pages	44-60
	Keywords
	Abstract	The work of innovation management involves cross-functional coordination among specialists and managers with different work orientations, time horizons, professional backgrounds, and values (Ford and Randolph, 1992). While strong connections across functions are critical for new product development success (Green et al., 2000), some managers may be more adept at fostering effective cross-functional relationships than others. In this article, the authors empirically examine the factors that distinguish reputationally effective innovation workers from their less effective peers. Drawing on the work of Tsui (1984, 1994), reputational effectiveness is defined as the degree to which a manager has been responsive to the needs and expectations of constituents. This research examines the relational skills and interaction patterns of more (versus less) reputationally effective managers. A large business unit of a Fortune 500 telecommunications firm provided the context for our study. Using a two-phase approach, the authors first captured the social network patterns of 268 managers from marketing, research and development (R&D), manufacturing, and other business functions that were involved in the new product development process. In addition, the reputational effectiveness of each person who was identified as a member of the network was measured. In the second phase, the authors examined the relational competencies (e.g., role-taking ability, interpersonal control, openness) of the managers who participated in Phase I of the research. As predicted, the results indicate that role-taking ability is related positively to a manager's reputational effectiveness. No support, however, was found for the relationship between interpersonal control and reputational effectiveness. Interestingly, the authors found evidence of an inverse relationship between openness and effectiveness. By sharing too much information?or alternatively information that does not relate to the task at hand?the reputational effectiveness of a manager is damaged. Importantly, the results reveal that the social network characteristics of a reputationally effective manager differ from those of less effective managers. Closeness centrality, a measure of the degree of access one has to other organizational members, was associated strongly with reputational effectiveness. The results demonstrate that managers who are successful in working across functions appreciate the cognitive and emotional perspectives of diverse constituents and develop relationship ties that provide them with ready access to others across the organization.

	Title	Two-state expansion and collapse of a polypeptide			Type	Journal Article
	Year	2000	Publication	Journal of Molecular Biology	Abbreviated Journal	J Mol Biol
	Volume	301	Issue	4	Pages	1019-1027
	Keywords	Animals; Computer Simulation; Cytochrome c Group/chemistry/metabolism; Horses; Kinetics; Lasers; Models, Chemical; Peptides/chemistry/metabolism; Protein Conformation; Protein Denaturation; *Protein Folding; Spectrometry, Fluorescence; Temperature; Thermodynamics
	Abstract	The initial phase of folding for many proteins is presumed to be the collapse of the polypeptide chain from expanded to compact, but still denatured, conformations. Theory and simulations suggest that this collapse may be a two-state transition, characterized by barrier-crossing kinetics, while the collapse of homopolymers is continuous and multi-phasic. We have used a laser temperature-jump with fluorescence spectroscopy to measure the complete time-course of the collapse of denatured cytochrome c with nanosecond time resolution. We find the process to be exponential in time and thermally activated, with an apparent activation energy approximately 9 k(B)T (after correction for solvent viscosity). These results indicate that polypeptide collapse is kinetically a two-state transition. Because of the observed free energy barrier, the time scale of polypeptide collapse is dramatically slower than is predicted by Langevin models for homopolymer collapse.

	Title	Mucosal antibodies can be measured in air-dried samples of saliva and feces			Type	Journal Article
	Year	1998	Publication	Journal of Immunological Methods	Abbreviated Journal
	Volume	215	Issue	1–2	Pages	163-172
	Keywords	Saliva; Feces; IgA; IgG; Air-drying
	Abstract	IgA antibodies reflecting airways or intestinal mucosal immune responses can be found in saliva and feces, respectively, and IgG antibodies reflecting serum antibodies can be found in saliva. In this study, antibodies were detected in samples of saliva and feces which had been air-dried at room temperature (+20°C) or +37°C, and stored at these temperatures for up to 6 months. In saliva the antibody levels increased, while the antibodies in feces decreased upon storage. The individual IgA antibody concentrations which were adjusted by using the ratios of specific IgA/total IgA were relatively stable in both saliva and feces, and correlated with corresponding antibody levels in samples which had been stored at -20°C. The results indicate that air-dried saliva and feces can be used for semiquantitative measurements of mucosal antibodies, even after prolonged storage at high temperatures and lack of refrigeration.

	Title	Concurrent Conditional Discrimination Tests of Transitive Inference by Macaque Monkeys: List Linking			Type	Journal Article
	Year	1996	Publication	Journal of Experimental Psychology: Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	22	Issue	1	Pages	105-117
	Keywords
	Abstract	Processing of serial information was assessed by training six macaques on a five-item list of objects arranged into the four conditional pairs, A-B+, B-C+, C-D+, and D-E+. An analogous list (F through J) was similarly trained. Subsequently, both lists were linked by training on E-F+, a pair that provided adjacent elements from each list. Then, all unique and trained object pairs from both lists were presented as a test. Results indicated that the objects were retained as a single, linearly organized list with choice accuracy directly related to interitem distance between paired objects. A second experiment explored the consequences of incidence of conflicting information on list organization. In both experiments, selections depended on representational processes and supported the view that monkeys and pigeons retain serial lists in qualitatively different ways.

	Title	Detour behaviour in horses (Equus caballus)			Type	Journal Article
	Year	2011	Publication	Journal of Ethology	Abbreviated Journal	J. Ethol.
	Volume	29	Issue	2	Pages	227-234
	Keywords	Detour behaviour; Equus caballus; Horses; Lateralization; Spatial reasoning
	Abstract	The objective of this study was to investigate the ability of horses (Equus caballus) to detour around symmetric and asymmetric obstacles. Ten female Italian saddle horses were each used in three detour tasks. In the first task, the ability to detour around a symmetrical obstacle was evaluated; in the second and third tasks subjects were required to perform a detour around an asymmetrical obstacle with two different degrees of asymmetry. The direction chosen to move around the obstacle and time required to make the detour were recorded. The results suggest that horses have the spatial abilities required to perform detour tasks with both symmetric and asymmetric obstacles. The strategy used to perform the task varied between subjects. For five horses, lateralized behaviour was observed when detouring the obstacle; this was consistently in one direction (three on the left and two on the right). For these horses, no evidence of spatial learning or reasoning was found. The other five horses did not solve this task in a lateralized manner, and a trend towards decreasing lateralization was observed as asymmetry, and hence task difficulty, increased. These non-lateralized horses may have higher spatial reasoning abilities.

	Title	Early management of race-bred weanlings and yearlings on farms			Type	Journal Article
	Year	2001	Publication	Journal of Equine Veterinary Science	Abbreviated Journal	J. Equine Vet. Sci.
	Volume	21	Issue	6	Pages	279-283
	Keywords	Equine, management, growth, nutrition, marketing
	Abstract	A total of 58 Thoroughbred and Quarter Horse farms that managed 1,987 weanlings and yearlings responded to a survey designed to better characterize early management of racing prospects. Average age at weaning was 5.5 months and over half of all farms kept almost three-fourths of all weanlings to be placed in pre-race training. Variation in feeding practices was evident and while well over half of all farms provided balanced nutrient supply to young horses, 20% to 40% likely fed unbalanced diets. An obvious preference existed for semi-confinement in young horses with plenty of free exercise. The majority of farms reported that young prospects were fed and managed for a moderate rate of growth. Forced exercise occurred to a much larger extent with yearlings than weanlings and 40% of farms described the footing as soft, but not deep. Response to the prevalence of developmental orthopedic diseases appeared somewhat guarded, and average injury rate was low on farms that attributed much of injury to horses playing too hard. Technological advancements such as photoperiod manipulation in broodmares were widely used, while valuable tools such as body condition scoring were utilized to a lesser extent.

	Title	Behavioral and physiological responses to stabling in naive horses			Type	Journal Article
	Year	2005	Publication	Journal of Equine Veterinary Science	Abbreviated Journal	J. Equine Vet. Sci.
	Volume	25	Issue	4	Pages	164-170
	Keywords
	Abstract	The purpose of this study was to investigate the response of horses to confinement and isolation in a stable (indoor individual housing) for the first time using behavioral indices, heart rate, and salivary cortisol concentration. Six naive 2-year-old Australian Stock Horse fillies were examined at 4-hour intervals over 24 hours in an outdoor group paddock followed by 24 hours in indoor individual housing. Behavioral observations and scores and heart rates were recorded and saliva samples were taken at each interval. During stabling, all horses became agitated and demonstrated increased vocalization and movement. Behavioral scores were significantly higher in the indoor individual housing (P < .001). No significant difference in heart rates between the two environments was detected. Mean salivary cortisol did not increase significantly (2 ng/mL ± 1.4 ng/mL in outdoor group paddock vs 2.5 mL ± 1.2 ng/mL in indoor individual housing). No diurnal rhythm in salivary cortisol was evident in either the outdoor group paddock or indoor individual housing. The results of this study highlight that a combination of behavioral and physiological measures allow better understanding of stress, where one measurement may be misleading. First time stabling of horses elicited marked behavioral responses indicative of stress that were not reflected in increased heart rates or salivary cortisol concentrations. The lack of a diurnal cortisol rhythm and the comparatively high basal cortisol concentrations found in the outdoor group paddock environment may imply that the fillies were already stressed; therefore, stabling did not cause further aberrations detectable by salivary cortisol analysis.

	Title	Equine Personality: Association with Breed, Use and Husbandry Factors			Type	Journal Article
	Year	2018	Publication	Journal of Equine Veterinary Science	Abbreviated Journal
	Volume		Issue		Pages
	Keywords	Horse; Personality; Behavior; Breed; Use; Survey
	Abstract	Abstract Temperament can be defined as innate properties of the nervous system whereas personality includes the complex behavioral traits acquired through life. Association between personality and behavior is important for breeding, selection, and training of horses. For the first time, we evaluated if equine personality components previously identified in Japan and Europe were consistent when applied to American horses. We examined the association of personality with breed, age, sex, management, training, stereotypies and misbehaviors. Materials and Methods The owner directed personality survey consisted of 25 questions. An online version of the survey was created. The principal component analysis (PCA) method was used to associate behavioral traits with personality components. Factor analysis with orthogonal transformation was performed on scores for personality related questions. Results 847 survey responses were used. Quarter horses, “other” breed and Thoroughbred were the most common breeds. Three principal personality components were extracted as each behavioral trait belonged to one of these three components. Arabians, Thoroughbreds, Saddlebreds and Walking horses were the most nervous and Quarter horses, Paints, Appaloosas and Drafts were the least nervous. No trained discipline was significantly associated with any personality component. There were no significant associations between stereotypies and misbehaviors and nervous or curious personality. Conclusions For the first time in predominantly American horses, we have evaluated personality components and their association with breed, age, sex, training discipline and stereotypies. We refute links between personality and trained discipline and confirm the lack of association between nervous personality and stereotypies and misbehaviors.
