Learning Management System Migration: An Analysis of Stakeholder Perspectives
Tom G Ryan,Mary Toye,Kyle Charron,Gavin Park
International Review of Research in Open and Distance Learning , 2012,
Abstract: In this mixed methods study the authors describe the institution-level perceptions of stakeholders transitioning to a new learning management system (LMS). We address issues related to change, the institution’s administration of the transition process, problems encountered, and realized learning via online survey data collection, analysis, and interpretation. We further detail results of a faculty survey, which sought to illuminate the LMS transition experience. The summation includes suggestions for institutions as they prepare for, and move through, foreseeable LMS change and transition.
The Effects of Podcasting on College Student Achievement and Attitude
Jeff Francom,Tom Ryan,Mumbi Kariuki
Journal of the Research Center for Educational Technology , 2011,
Abstract: This mixed methods study investigated the impact of weekly podcasts, written and recorded by course instructors to summarize college course content, on student achievement and attitudes. Weekly summative podcasts were posted on an Internet website in Windows Media format and downloaded by college students. After four weeks of podcasts, students were assessed and evaluated and results were compared to similar classes that did not use podcasts. Students completed a questionnaire and were interviewed to record their views, perceptions, and attitudes. Participating teachers were also interviewed. Although not generalizable, the results of this study indicate that weekly podcast summaries were an effective teaching tool which produced improved student achievement and caused students to view their evaluation preparation and comprehension of course content optimistically.
The Impact of Movements and Animal Density on Continental Scale Cattle Disease Outbreaks in the United States

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0091724
Abstract: Globalization has increased the potential for the introduction and spread of novel pathogens over large spatial scales necessitating continental-scale disease models to guide emergency preparedness. Livestock disease spread models, such as those for the 2001 foot-and-mouth disease (FMD) epidemic in the United Kingdom, represent some of the best case studies of large-scale disease spread. However, generalization of these models to explore disease outcomes in other systems, such as the United States’s cattle industry, has been hampered by differences in system size and complexity and the absence of suitable livestock movement data. Here, a unique database of US cattle shipments allows estimation of synthetic movement networks that inform a near-continental scale disease model of a potential FMD-like (i.e., rapidly spreading) epidemic in US cattle. The largest epidemics may affect over one-third of the US and 120,000 cattle premises, but cattle movement restrictions from infected counties, as opposed to national movement moratoriums, are found to effectively contain outbreaks. Slow detection or weak compliance may necessitate more severe state-level bans for similar control. Such results highlight the role of large-scale disease models in emergency preparedness, particularly for systems lacking comprehensive movement and outbreak data, and the need to rapidly implement multi-scale contingency plans during a potential US outbreak.
Vacunas anti-rotavirus: Al fin una realidad
O'Ryan G,Miguel;
Revista chilena de infectología , 2005, DOI: 10.4067/S0716-10182005000600007
Abstract: rotavirus is the most common cause of severe acute diarrhea among children less than 3 years of age. this infection causes 25 million medical visits, 2 million hospitalizations and 440.000 deaths every year worldwide. the development of rotavirus vaccines has followed a long and difficult path seriously hampered by the abrupt withdrawal of rotashield? in 1999 due to its association with intestinal intussusception. after six years of intense research, the world celebrates the licensing of two new rotavirus vaccines, different in formulation and administration schemes albeit clearly safe and not associated with intussusception as demonstrated by large phase iii trials including more than 60.000 children. these vaccines, rotarix? from glaxo smithkline biologicals and rotateq? from merck sharp & dohme, have demonstrated to be highly efficacious against severe rotavirus gastroenteritis caused by the most prevalent serotypes. prompt incorporation of these new vaccines into the immunization programs of countries, especially those in the poorest areas of the world where these vaccines are most needed, will require joint efforts between governments, vaccine manufacturers, international and non-governmental organizations and foundations
Reflexiones y sentimientos desde un equipo de voluntarios del Ministerio de Salud y el Colegio Médico de Chile, después del terremoto reciente
O'RYAN G,MIGUEL;
Revista médica de Chile , 2010, DOI: 10.4067/S0034-98872010000300002
Abstract: the experience of a group of 9 doctors and 6 nurses, most of them younger than 30years of age, whom were part of the several volunteer groups directed towards the most damaged earthquake regions, is described. the team had to overcome a number of intense personal emotions related with the magnitude of the destruction, especially in the "adobe"-constructed houses and villages, in order to provide useful medical support. moving out of the hospital setting, reaching out to the community in schools and emergency posts proved to be important in rural communities. an appropriate coordination of the volunteer groups, with the simultaneous action of municipal and state health authorities, together with well-guided leadership, was critical for an effective response in the larger city of talcahuano /hualpén. within the second week of the aftermath, acute respiratory and intestinal infections were the most common medical complaints together with intense -in many cases severe- emotional distress associated mostly with fear to after shakes ("replicas"), tsunami, and social unrest. the severe earthquake that struck chile has left many lessons for the future that will need to be analyzed seriously and with the conviction that effective and timely prevention of catastrophic aftermath consequences, although costly, must be a key element of the country's development plan. more importantly, the hundreds if not thousands of volunteers from a variety of health related professions that were moved by the scenes of suffering, and whom responded to individual or group initiatives, allow to foresee that the nation has the moral stamina required to overcome the tragedy and become a better society.

Vacunas anti-rotavirus: Al fin una realidad New rotavirus vaccines: A reality at last

Abstract: Rotavirus es la primera causa de diarrea aguda grave en ni os bajo 3 a os de edad en el mundo. Esta infección es responsable de 25 millones de consultas, 2 millones de hospitalizaciones y 440.000 muertes por a o en ni os con menos de 5 a os. El desarrollo de vacunas anti-rotavirus ha sido un camino largo y tortuoso marcado por la abrupta caída de Rotashield en 1999 debido a su asociación con invaginación intestinal. Luego de seis a os de intensa investigación, el mundo celebra la licencia de dos nuevas vacunas que, a pesar de ser diferentes en su formulación y forma de administración, han demostrado ser seguras y no asociadas a invaginación intestinal, en estudios de Fase III de gran magnitud, que enrolaron más de 60.000 ni os. Estas dos vacunas, Rotarix de Glaxo SmithKline Biologicals y Rotateq de Merck Sharp & Dohme son altamente eficaces contra diarrea grave causada por rotavirus de los serotipos más prevalentes en el mundo. La incorporación de estas vacunas, más temprano que tarde, especialmente en los países más pobres del mundo, requerirá de un esfuerzo conjunto de los gobiernos, laboratorios productores, organismos internacionales y no gubernamentales y fundaciones de beneficencia Rotavirus is the most common cause of severe acute diarrhea among children less than 3 years of age.

The emerging educator as leader and action researcher
Thomas G. RYAN
International Electronic Journal of Elementary Education , 2009,
Abstract: The 320 pre-service educators in this inquiry were viewed as emerging classroom teacherswho were leading while grappling with new personal experiences which informed andguided each during the pre-service year. The written account evidence supported ourresulting inferences, discussion and conclusions and demonstrated the leadership requiredwithin pre-service. It was the analysis and synthesis of practicum reflections thatilluminated core beliefs, attitudes and needs of emerging action researchers as theydeveloped a professional and personal understanding of leadership, teaching and self.
