Rebalancing Liberalism: Discourse Theory as a Remedy to the Effects of Accelerated Modernity

Balancing the rights of the individual to lead a self-determined life while accommodating traditional identity groups is a central goal of liberal society. The modernity argument suggests that processes within modernity are capable of liberalizing societies. The emergence of modern information technology has drastically increased the speed of the liberalizing influence of modernity to the point that this goal is threatened. However, using tools found within discourse theory, traditional identity groups may be able to mitigate these incoming influences to such a degree as to rebalance these liberal goals

Northwest Tropical Atlantic Station (NTAS) : velocity data report for deployments 1 to 5

This report presents velocity data from the Northwest Tropical Atlantic Station (NTAS) deployments 1 through 5, from March 30, 2001, to February 28, 2006. The NTAS project has maintained a series of moorings near 14°50'N, 51°00'W in the northwest tropical Atlantic for air-sea flux measurement. The moorings include a surface buoy outfitted with Air- Sea Interaction Meteorology (ASIMET) systems for determination of bulk air-sea fluxes and oceanographic sensors along the upper 120 m of the mooring line. This report describes and presents the velocity data recovered from current meters and Acoustic Doppler Current Profilers (ADCPs) during the first five years of the NTAS project.Funding was provided by the National Oceanic and Atmospheric Administration under Grant No. NA09OAR432012

Spiders (Arthropoda: Aranea) From Deciduous Forest Litter of the Ouachita Highlands

One hundred two litter samples were collected from oak/hickory and maple/beech forests in the Ouachita Highlands of western Arkansas July 1991-June 1992. Berlese residues of these collections produced 17 families, 51 genera, and 56 species of spiders, and included 19 species previously unreported for the state of Arkansas

A Holistic and Multifaceted Model for Ill-Structured Experiential Problem-Based Learning: Enhancing Student Critical Thinking and Communication Skills

Educators have observed that our college graduates are not equipped with the complex problem-solving skills to contribute to the many challenges of industry and other professional contexts. This paper describes an experiential problem-based multifaceted instructional design and teaching model at the New York University School of Professional Studies, developed by instructional design and technological experts. The model combines traditional instructional design, evidence-based strategies, and learning theories for development of student critical thinkers who can transfer their new knowledge and capabilities to industry and various other professional contexts. This model includes unique faculty and student orientations and guides, students as active contributors, instructors as facilitators, and collaborative projects. Student surveys of four cohorts (68 students) over four academic quarters indicated strong positive results. Students practiced through experiential problem-based learning and thereby learned critical and creative thinking that increased their communication skills. The program, to continue through New York University, can also be adapted for professionally-oriented education degrees, certifications, and lifelong learning courses

Resolving the interactions of ocean acidification and temperature on coral calcification media pH

This work was supported by the UK Natural Environment Research Council (award NE/I022973/1) to AAF and NA.Ocean acidification typically reduces the calcification rates of massive Porites spp. corals but increasing seawater temperatures (below the stress and bleaching threshold) can offset this effect. Here we use δ11B to reconstruct the pH of the calcification media (pHECM) used to precipitate the skeleton in poritid corals cultured over a range of seawater pCO2 and at 25°C and 28°C. Increasing temperature had no significant effect on pHECM at high pCO2 although corals increased their calcification rates. pHECM was reduced at 28°C compared to 25°C at low seawater pCO2, although calcification rates remained constant. Increasing calcification rates could reflect the positive influence of temperature on aragonite precipitation rate, an increase in calcification media saturation state or a change in the concentration/behaviour of the skeletal organic matrix. The 2 temperatures utilized in this study were within the seasonal range at the coral collection site and do not represent a heat stress scenario. Increasing seawater temperatures may promote calcification in some corals in the future but are unlikely to benefit the majority of corals, which are already living close to their maximum thermal tolerance limits.Publisher PDFPeer reviewe

Phosphatidylinositol 3-kinase activation is required for insulin-stimulated sodium transport in A6 cells

Insulin stimulates amiloride-sensitive sodium transport in models of the distal nephron. Here we demonstrate that, in the A6 cell line, this action is mediated by the insulin receptor tyrosine kinase and that activation of phosphatidylinositol 3-kinase (PI 3-kinase) lies downstream of the receptor tyrosine kinase. Functionally, a specific inhibitor of PI 3-kinase, LY-294002, blocks basal as well as insulin-stimulated sodium transport in a dose-dependent manner (IC50 approximately 6 microM). Biochemically, PI 3-kinase is present in A6 cells and is inhibited both in vivo and in vitro by LY-294002. Furthermore, a subsequent potential downstream signaling element, pp70 S6 kinase, is activated in response to insulin but does not appear to be part of the pathway involved in insulin-stimulated sodium transport. Together with previous reports, these results suggest that insulin may induce the exocytotic insertion of sodium channels into the apical membrane of A6 cells in a PI 3-kinase-mediated manner

An empirical investigation into the propensity of reckless decision making within the high pressure environment of Deal or No Deal.

This paper discusses human attitudes towards risk and the development of expected utility models, laying the foundations for the creation of prospect theory in 1979. It proceeds to analyse the decisions of contestants on the popular TV game show Deal or No Deal to attempt to observe any evidence of differing levels of risk aversion under losses and gains as predicted by prospect theory. The results reveal some evidence of decreased risk aversion in the domains of losses and gains, with contestants displaying behaviour consistent with the break-even and house-money effects. We conclude there may be enough evidence of variable reference points to warrant further investigation, and propose suggestions for further researc
