LEADERSHIP STYLES OF STATE EXTENSION SPECIALISTS

Cooperative extension is one of three components, along with teaching and research that form the mission of land grant universities. The focus of extension work is to take knowledge gained through research conducted at the university, and disseminate the information, in a practical manner to the end user. In most instances, extension work revolves around agriculture. Within the extension system are personnel that help to foster this program of educating clientele who work in the agricultural industry. County level agents are in place to teach and address the needs of local constituents, specialists are generally housed at the university campus and are hired for their expertise in a specific field of agriculture, and administrators help to keep the system functioning. Many studies have been conducted on the leadership characteristics of county agents and extension administrators, however the current knowledge base concerning leadership behaviors of extension specialists is lacking. Traditionally, specialists were strictly used as a resource for subject matter information; however, changes overtime to cooperative extension have seen specialists move to a leadership position that involves leading agents groups and conducting programing that directly serves the clientele. With newly acquired expectations to perform in a leadership capacity, yet without training or educational background to ensure these skills, there is potential for complications to arise. Using a mixed methodological approach, this sequential explanatory study was conducted using Burn’s (1978) transformational leadership as a theoretical framework, with the purpose of examining current transformational leadership characteristics among extension specialists in addition to gaining information concerning demographic and professional information pertaining to this group. The sample group consisted of equine extension specialists, an initial survey was sent which contained questions relating to educational background, make-up and tenure of their position, as well as the Multifactor Leadership Questionnaire (MLQ) to analyze self-perceived transformational leadership characteristics. This survey was followed by a voluntary individual interview with the researcher. The purpose of the semi-structured interview was to gain a broader example of the leadership perspectives of this particular group. Although no significant connections could be made concerning demographic information and MLQ leadership scores, the group as a whole registered below average for displaying transformational leadership characteristics, ranking in the 40th percentile for composite MLQ scores compared to the general population. The interview data showed that as a whole there was agreement with the concepts of transformational leadership, however MLQ scores and anecdotal evidence show that practical application of transformational leadership is lacking. Most participants indicated they did not feel prepared for their job, and many indicated that interpersonal relationship skills were used more often than their degree specialization. The findings from this study may help to encourage leadership training focused towards extension specialists, and to emphasize the need for leadership skills within this position

Horse-Related Injuries: Causes, Preventability, and Where Educational Efforts Should be Focused

A high percentage of equestrians will experience accidents, with different degrees of severity, throughout their riding careers. Horse-related injuries have the highest likelihood of requiring hospitalization based on individuals visiting US emergency departments. Studies have shown that the majority of injured riders said they could have prevented the accident and the injury was due to rider/handler error. Therefore, equestrians reported their injuries, and a panel of experts analyzed these reports to better understand the causes, how to prevent, and where to invest educational resources to generate a reduction in horse-related accidents. The majority of riders reported intermediate riding skills, most accidents occurred in the arena, and most were preventable. The most severe accidents occurred when the weather played a major role, as opposed to the least severe accidents when riders were in the horse’s space. Avoidable accidents included when tack broke, as opposed to unavoidable accidents such as horses slipped or fell. Educational Impact Index was calculated with combined results of the cause of injury, avoidability, and severity. Other humans, horse spooked, and tack/equipment problems were the main causes of accidents with the highest educational impact index, and authors believe that educational efforts should be focused on these categories

Comparative salivary gland transcriptomics of sandfly vectors of visceral leishmaniasis

BACKGROUND: Immune responses to sandfly saliva have been shown to protect animals against Leishmania infection. Yet very little is known about the molecular characteristics of salivary proteins from different sandflies, particularly from vectors transmitting visceral leishmaniasis, the fatal form of the disease. Further knowledge of the repertoire of these salivary proteins will give us insights into the molecular evolution of these proteins and will help us select relevant antigens for the development of a vector based anti-Leishmania vaccine. RESULTS: Two salivary gland cDNA libraries from female sandflies Phlebotomus argentipes and P. perniciosus were constructed, sequenced and proteomic analysis of the salivary proteins was performed. The majority of the sequenced transcripts from the two cDNA libraries coded for secreted proteins. In this analysis we identified transcripts coding for protein families not previously described in sandflies. A comparative sandfly salivary transcriptome analysis was performed by using these two cDNA libraries and two other sandfly salivary gland cDNA libraries from P. ariasi and Lutzomyia longipalpis, also vectors of visceral leishmaniasis. Full-length secreted proteins from each sandfly library were compared using a stand-alone version of BLAST, creating formatted protein databases of each sandfly library. Related groups of proteins from each sandfly species were combined into defined families of proteins. With this comparison, we identified families of salivary proteins common among all of the sandflies studied, proteins to be genus specific and proteins that appear to be species specific. The common proteins included apyrase, yellow-related protein, antigen-5, PpSP15 and PpSP32-related protein, a 33-kDa protein, D7-related protein, a 39- and a 16.1- kDa protein and an endonuclease-like protein. Some of these families contained multiple members, including PPSP15-like, yellow proteins and D7-related proteins suggesting gene expansion in these proteins. CONCLUSION: This comprehensive analysis allows us the identification of genus- specific proteins, species-specific proteins and, more importantly, proteins common among these different sandflies. These results give us insights into the repertoire of salivary proteins that are potential candidates for a vector-based vaccine

Equine Viral Arteritis

Equine viral arteritis (EVA) is a contagious disease of horses and other equine species caused by equine arteritis virus (EAV) that is found in horse populations in many countries.This article discusses transmission, diagnosis, treatment, outcomes, and prevention
