Troubling stoicism:Sociocultural influences and applications to health and illness behaviour

In light of the ambiguity of meanings attributed to the concept of stoicism we critically explore its use as a label to explain and describe health and illness behaviour, juxtaposing the often negative portrayals of contemporary stoicism against its classical and philosophical origins. By reflecting critically on the term ‘stoicism’, its application and dimensionality, we show how the term has evolved from classical to contemporary times in relation to changing context, and explore different understandings of the term across medical and health literature. We attend to sociocultural factors that are seen to influence the conceptualization of stoicism such as generational influences, gender and geographies. We make the assertion that by applying the label of ‘stoicism’ as it is known today, there is a danger of too readily accepting a term that masks particular health behaviours while missing an array of sociological factors that are important to how people deal with adversity arising from chronic health problems. We therefore encourage further questioning of this term. </jats:p

Social and Student Engagement and Support: The Sloan-C Quality Scorecard for the Administration of Online Programs

As combinations of place-based, blended and fully online education proliferate, so do options for support and services. Regional accreditors provide criteria for student support. Aligning with regional criteria, the Sloan-C Quality Scorecard for the Administration of Online Programs is a useful way for institutions to measure and compare the quality of social and student engagement and support. The Scorecard aids quality efforts in institutional strategic planning, compliance reporting, and internal and external evaluation. Focusing on two of the nine categories of quality indicators—Social and Student Engagement and Student Support—this paper illustrates some ways institutions can meet Scorecard indicators while complementing regional accreditation guidelines

THE ROAD TO RETENTION: A CLOSER LOOK AT INSTITUTIONS THAT ACHIEVE HIGH COURSE COMPLETION RATES

Although online course completion rates are commonly believed to be lower than in other delivery modes, some programs achieve equal or better course completion rates. This issue presents studies that suggest certain practices contribute to student success. Readers are invited to contribute to work-inprogress on key factors for a framework of effective practice

GETTING BETTER: ALN AND STUDENT SUCCESS

In the U.S., only 38 of every 100 ninth graders enroll in college; of these 38, only 18 complete bachelors’ degrees within six years. Asynchronous learning networks (ALN)—asynchronous, highly interactive, instructor-led, resource-rich, cohort-based learning—can yield high success rates. Growing demand for online education and the expectation among higher education leaders that ALN learning outcomes will exceed face to face outcomes reflect belief in ALN’s power to engage learners. Sloan-C’s body of research confirms that ALN is especially suited for the anytime, anywhere, affordable access that is responsive to learners in a knowledge society. In fact, the original principles of ALN are the same principles that characterize ALN programs that have high student success rates. This paper includes vignettes from two and four-year ALN programs that have used these principles to achieve high success rates

Three-dimensional ring current decay model

This work is an extension of a previous ring current decay model. In the previous work, a two-dimensional kinetic model was constructed to study the temporal variations of the equatorially mirroring ring current ions, considering charge exchange and Coulomb drag losses along drift paths in a magnetic dipole field. In this work, particles with arbitrary pitch angle are considered. By bounce averaging the kinetic equation of the phase space density, information along magnetic field lines can be inferred from the equator. The three-dimensional model is used to simulate the recovery phase of a model great magnetic storm, similar to that which occurred in early February 1986. The initial distribution of ring current ions (at the minimum Dst) is extrapolated to all local times from AMPTE/CCE spacecraft observations on the dawnside and duskside of the inner magnetosphere spanning the L value range L = 2.25 to 6.75. Observations by AMPTE/CCE of ring current distributions over subsequent orbits during the storm recovery phase are compared to model outputs. In general, the calculated ion fluxes are consistent with observations, except for H(+) fluxes at tens of keV, which are always overestimated. A newly invented visualization idea, designated as a chromogram, is used to display the spatial and energy dependence of the ring current ion differential flux. Important features of storm time ring current, such as day-night asymmetry during injection and drift hole on the dayside at low energies (less than 10 keV), are manifested in the chromogram representation. The pitch angle distribution is well fit by the function, J(sub o)(1 + Ay(sup n)), where y is sine of the equatorial pitch angle. The evolution of the index n is a combined effect of charge exchange loss and particle drift. At low energies (less than 30 keV), both drift dispersion and charge exchange are important in determining n

INTRODUCTION TO THE SPECIAL ISSUE ON THE RIGHT TO EDUCATION

n the 60 years since the Declaration, changes have swept higher education. The emergence of online education promises that growth in its quality, scale and breadth could insure that education becomes a right. Sloan-C research abundantly demonstrates that online education is effective for learning, especially for encouraging reflection, interaction, diversity and collaboration. It can take advantage of cost efficiencies, especially through curriculum redesign and shared resources. It provides access to more learners and more kinds of learners at their own chosen times and places. Although teaching and learning online may take more time and effort, the growth of online education in the United States to 20% of the entire college population shows that faculty and students readily engage online. Nevertheless, there is still tremendous potential for growth
