    The South American tamarin, genus Saguinus is used extensively as a model for interpreting human disease. Recently, techniques for estimating the age from skeletons of wild-caught tamarins have been requested by biomedical researchers. These skeletal aging techniques are subsequently used as an aid in documenting the timing of disease onset and latency periods. Skeletal age changes are examined in 157 Saguinus fusaicollis and 59 Saguinus oedipus specimens of known age. The entire approximate 15 year life span of these animals is represented within the sample. The species are treated independently for all analyses. Documentation of the ontogenetic skeletal changes in immature specimens is made for the sequences and timing of dental eruption and epiphyseal union and for the chronology of long bone growth. For adult specimens, the age-related patterns associated with intracortical bone remodeling and mid-diaphyseal cortex size and shape are documented. Results of this research indicate that the greatest accuracy for estimating age in these species is obtained within the developmental growth stage, from birth to maturity. During this stage, accurate age assignment can be made to within approximately three months. For aging adult specimens, the trends of intracortical bone remodeling and mid-diaphyseal cortex size and shape exhibit extensive intraspecies variation and thus are applicable with limited accuracy

    Conferencing: An Exploration into Connectivity, Content, and Community

    Get PDF
    The electronic conference, Bits and Bytes: An Online Symposium on the Evolution of Technology in Education, was a joint initiative of the Faculty of Education at Memorial University of Newfoundland and the Centre for Advanced Placement Education at Discovery Collegiate. The format of this electronic conference (e-conference) was similar to that of an on-site conference, with a call for submissions, a peer-reviewed processing of these proposals, and a presentation of the accepted proposals. However, the participants of this e-conference never met in a specific locale in a synchronous time frame, as is the case with traditional conferences. The authors and participants interacted in a virtual sense, with presentations, commentary and feedback taking place in an asynchronous time frame

    Cyber Insurance Effects on Cyber Hygiene: Does the Homeostatic Effect Apply?

    Get PDF
    A theoretical framework and research strategy is proposed to gain insight into perceptions and decisions as to how SMBs make decisions regarding cybersecurity hygiene measures, which could lead to betterinformed decisions regarding insurance as part of an ISA program, as well as have a bearing on policy structures and pricing for such insurance. This is because the definition of “cybersecurity hygiene habits”(CHH) as a task appears to vary within the industry and makes the practice hard to measure and evaluate. Research suggests that there may be a poorly understood connection between CHHs undertaken by organizations and their perceptions and/or adoption of cybersecurity insurance as well, thus leading to gaps or holes within business security perimeters. Homeostatic Risk Theory (HRT) has been observed in other venues in which the use of risk mitigation measures (including insurance) leads to more risky behavior; this may have a bearing on why so many organizations, particularly Small and Medium Businesses (SMBs) are very slow to adopt Information Security Assurance (ISA) measures at all or do so minimally. This paper presents a theoretical framework and proposed research, which will provide greater clarity on these issues while highlighting areas where further research is required

    Asystole following Reintubation during Suspension Laryngoscopy

    Transient increase in heart rate and mean arterial pressure commonly occur during manipulation of the airway via direct laryngoscopy. This phenomenon is understood to be due to a sympathetic nervous system reflex causing an increase in plasma catecholamines. Rarely, severe bradycardia and possible asystole can occur following laryngoscopy. One previous report described asystole during suspension laryngoscopy after uneventful direct laryngoscopy. Here we report a case of asystole occurring at the time of reinsertion and cuff inflation of an endotracheal tube in a patient who had been hemodynamically stable during initial direct laryngoscopy and the ensuing suspension laryngoscopy. The asystole was immediately recognized and successful cardiopulmonary resuscitation was performed with the patient returning to baseline sinus rhythm. Cardiac arrest following laryngoscopy is rare. This case highlights the importance of continued vigilance even after the initial manipulations of the airway by both direct laryngoscopy and suspension laryngoscopy are to be performed. Identifying patients who may benefit from premedication with a vagolytic drug may prevent adversity. Preoperative heart rate analysis can identify patients with strong vagal tone
