Tech It Up!

The new teaching technologies take many forms, both as learning tools and strategies. Combining new technology with traditional teaching techniques provides a variety in format presentation and learning styles, and is helpful to students in learning theory and workplace applications. The challenge as faculty is to incorporate many different teaching and learning methods in each lesson plan. Discussion focuses on why and how to divide the class session into smaller timeframe learning blocks, and how to intermingle many methods to break up the class hours. Activities that can be easily included and ways to rearrange the class schedule are addressed. By using many techniques as well as technologies, faculty provide practical and active experiences to increase students\u27 learning

Colleagues in Community: Faculty Building Collaborative Environments

Co/leagues in Community describes faculty building collaborative environments. It emphasizes faculty collaborative interaction for sharing teaching and learning experiences as a community. The framework for this sharing encompasses our lives as faculty-- the work, students, and organizational systems in which we find ourselves. This framework is slowly shifting from an instruction-based relationship to a new paradigm of faculty and students as members ofa learning community. Many faculty within the Embry-Riddle Extended Campus (EC) community have begun to make this shift. Some excellent examples are presented of EC faculty efforts toward community development

Rules of Engagement: Journalists’ attitudes to industry influence in health news reporting.

Health-related industries use a variety of methods to influence health news, including the formation and maintenance of direct relationships with journalists. These interactions have the potential to subvert news reporting such that it comes to serve the interests of industry in promoting their products, rather than the public interest in critical and accurate news and information. Here we report the findings of qualitative interviews conducted in Sydney, Australia, in which we examined journalists’ experiences of, and attitudes towards, their relationships with health-related industries. Participants’ belief in their ability to manage industry influence and their perceptions of what it means to be unduly influenced by industry raise important concerns relating to the psychology of influence and the realities of power relationships between industry and journalists. The analysis also indicates ways in which concerned academics and working journalists might establish more fruitful dialogue regarding the role of industry in health-related news and the extent to which increased regulation of journalist-industry relationships might be needed.NHMR

Growth and Antifungal Resistance of the Pathogenic Yeast, Candida Albicans, in the Microgravity Environment of the International Space Station: An Aggregate of Multiple Flight Experiences.

This report was designed to compare spaceflight-induced cellular and physiological adaptations of Candida albicans cultured in microgravity on the International Space Station across several payloads. C. albicans is a common opportunistic fungal pathogen responsible for a variety of superficial infections as well as systemic and more severe infections in humans. Cumulatively, the propensity of this organism to be widespread through the population, the ability to produce disease in immunocompromised individuals, and the tendency to respond to environmental stress with characteristics associated with increased virulence, require a better understanding of the yeast response to microgravity for spaceflight crew safety. As such, the responses of this yeast cultivated during several missions using two in-flight culture bioreactors were analyzed and compared herein. In general, C. albicans had a slightly shorter generation time and higher growth propensity in microgravity as compared to terrestrial controls. Rates of cell filamentation differed between bioreactors, but were low and not significantly different between flight and terrestrial controls. Viable cells were retrieved and cultured, resulting in a colony morphology that was similar between cells cultivated in flight and in terrestrial control conditions, and in contrast to that previously observed in a ground-based microgravity analog system. Of importance, yeast demonstrated an increased resistance when challenged during spaceflight with the antifungal agent, amphotericin B. Similar levels of resistance were not observed when challenged with the functionally disparate antifungal drug caspofungin. In aggregate, yeast cells cultivated in microgravity demonstrated a subset of characteristics associated with virulence. In addition, and beyond the value of the specific responses of C. albicans to microgravity, this report includes an analysis of biological reproducibility across flight opportunities, compares two spaceflight hardware systems, and includes a summary of general flight and payload timelines

Admissions recruitment effectiveness in private four-year colleges and universities.

In the battle to maintain enrollment levels, institutions are confronting many questions about effectiveness, including those that address admissions recruitment. Admissions directors face the problem of factors and forces that influence the effectiveness of recruitment activities. This study focused on selected factors--institutional characteristics, administrative structure for admissions, admissions plans and goals, and recruitment activities--and their influence on perceptions of admissions recruitment effectiveness. Survey respondents included 643 presidents, supervisors of admissions directors, and admissions directors. The findings revealed that only a small number of significant relationships existed among the variables. Institutional characteristics such as Carnegie Classification, Enrollments, and Region were not linked to administrator perceptions of effectiveness of achieving admissions goals or admissions recruitment activities. One characteristic, Level of Selectivity, showed the highest number of significant relationships; it was related to eight of thirteen admissions goals. The existence of strategic, marketing, enrollment management, and admissions plans was related to perceptions of the effectiveness of achieving admissions goals in 21% of the cases. Establishment of a goal for recruitment activities made a significant difference in perceptions of effectiveness for a number of recruitment activities. Although significance was not demonstrated for relationships among many of the variables, it was interesting that high levels of activity were documented for admissions plans, market research, admissions goals, recruitment activities, and activity evaluation measures. Plans, goals, and recruitment activities did not come forward as influential factors in perceptions of effectiveness of recruitment activities, yet institutions used them heavily. Mean effectiveness ratings of recruitment activities were higher when plans, market research studies and goals for admissions recruitment activities existed. These findings have important implications for admissions directors. They can be used as a basis for designing or changing admissions programs. Plans and goals need to be formulated specifying the types of students the institution wants to attract given characteristics deemed important. Market research studies and evaluation measures should be used to identify and select admissions goals, determine which admissions recruitment activities work in specific situations, and make changes in recruitment activities based on this information.Ph.D.EducationUniversity of Michigan, Horace H.

New constraints on the pyroclastic eruptive history of the Campanian volcanic Plain (Italy)

The ∼ 150 km3 (DRE) trachytic Campanian Ignimbrite, which is situated north-west of Naples, Italy, is one of the largest eruptions in the Mediterranean region in the last 200 ky. Despite centuries of investigation, the age and eruptive history of the Campanian Ignimbrite is still debated, as is the chronology of other significant volcanic events of the Campanian Plain within the last 200–300 ky. New 40Ar/39Ar geochronology defines the age of the Campanian Ignimbrite at 39.28 ± 0.11 ka, about 2 ky older than the previous best estimate. Based on the distribution of the Campanian Ignimbrite and associated uppermost proximal lithic and polyclastic breccias, we suggest that the Campanian Ignimbrite magma was emitted from fissures activated along neotectonic Apennine faults rather than from ring fractures defining a Campi Flegrei caldera. Significantly, new volcanological, geochronological, and geochemical data distinguish previously unrecognized ignimbrite deposits in the Campanian Plain, accurately dated between 157 and 205 ka. These ages, coupled with a xenocrystic sanidine component \u3e 315 ka, extend the volcanic history of this region by over 200 ky. Recent work also identifies a pyroclastic deposit, dated at 18.0 ka, outside of the topographic Campi Flegrei basin, expanding the spatial distribution of post-Campanian Ignimbrite deposits. These new discoveries emphasize the importance of continued investigation of the ages, distribution, volumes, and eruption dynamics of volcanic events associated with the Campanian Plain. Such information is critical for accurate assessment of the volcanic hazards associated with potentially large-volume explosive eruptions in close proximity to the densely populated Neapolitan region

A Strategy for Identifying and Disseminating Best Practice Innovations in the Care of Patients with Multiple Chronic Conditions or End-of-Life Care Needs.

Patients with multiple chronic conditions and those with end-of-life care needs experience high health care costs and needs for skilled coordination and well-trained staff. Focusing on these populations presents an opportunity to improve the patient experience toward the goal of more patient-centered care and reduced costs. Although innovative programs that provide better care to these patient populations have been developed, these innovations are often localized and not actively disseminated to other settings. This paper describes a quality-improvement project aimed at developing a process to identify best practices implemented in community-based clinical settings, develop a platform to share and disseminate these best practices, and facilitate the adoption of successful practices across other similar settings. The facilitation process involved structured coaching by clinicians and researchers experienced with practice change and quality improvement. The coaching component ensured that implementation teams receive guidance in the planning and adoption process, stay on track with implementation, and have access to timely support in addressing unanticipated barriers

The 322 ka Tiribí Tuff: stratigraphy, geochronology and mechanisms of deposition of the largest and most recent ignimbrite in the Valle Central, Costa Rica

The Tiribí Tuff covered much of the Valle Central of Costa Rica, currently the most densely populated area in the country (∼2.4 million inhabitants). Underlying the tuff, there is a related well-sorted pumice deposit, the Tibás Pumice Layer. Based on macroscopic characteristics of the rocks, we distinguish two main facies in the Tiribí Tuff in correlation to the differences in welding, devitrification, grain size, and abundance of pumice and lithic fragments. The Valle Central facies consists of an ignimbritic plateau of non-welded to welded deposits within the Valle Central basin and the Orotina facies is a gray to light-bluish gray, densely to partially welded rock, with yellowish and black pumice fragments cropping out mainly at the Grande de Tárcoles River Gorge and Orotina plain. This high-aspect ratio ignimbrite (1:920 or 1.1×10−3) covered an area of at least 820 km2 with a long runout of 80 km and a minimum volume outflow of 25 km3 (15 km3 DRE). Geochemically, the tuff shows a wide range of compositions from basaltic-andesites to rhyolites, but trachyandesites are predominant. Replicate new 40Ar/39Ar age determinations indicate that widespread exposures of this tuff represent a single ignimbrite that was erupted 322±2 ka. The inferred source is the Barva Caldera, as interpreted from isopach and isopleth maps, contours of the ignimbrite top and geochemical correlation (∼10 km in diameter). The Tiribí Tuff caldera-forming eruption is interpreted as having evolved from a plinian eruption, during which the widespread basal pumice fall was deposited, followed by fountaining pyroclastic flows. In the SW part of the Valle Central, the ignimbrite flowed into a narrow canyon, which might have acted as a pseudo-barrier, reflecting the flow back towards the source and thus thickening the deposits that were filling the Valle Central depression. The variable welding patterns are interpreted to be a result of the lithostatic load and the influence of the content and size of lithic fragments
