Variable tuition fees and widening participation: the marketing of English institutions through access agreements
This paper argues that the introduction of access agreements following the establishment of the Office for Fair Access (OFFA) has led to changes in the way that higher education institutions (HEIs) position themselves in the marketplace in relation to widening participation. However, the nature of these access agreements has led to obfuscation rather than clarification from the perspective of the consumer. This paper analyses OFFA's 2008 monitoring report and a sample of 20 HEIs' original 2006 and revised or updated access agreements (2008) to draw conclusions about the impact of these agreements on the notions of 'fair access' and widening participation. The authors conclude that institutions use access agreements primarily to promote enrolment to their own programmes rather than to promote HE generally. As a consequence of this marketing focus, previous differences between pre-92 and post-92 institutions in relation to widening participation and fair access are perpetuated leading to both confusion for consumers and an inequitable distribution of bursary and other support mechanisms for the poorest applicants to HE.</p
Nanoelectromechanical Resonator Arrays for Ultrafast, Gas-Phase Chromatographic Chemical Analysis
Miniaturized gas chromatography (GC) systems can provide fast, quantitative analysis of chemical vapors in an ultrasmall package. We describe a chemical sensor technology based on resonant nanoelectromechanical systems (NEMS) mass detectors that provides the speed, sensitivity, specificity, and size required by the microscale GC paradigm. Such NEMS sensors have demonstrated detection of subparts per billion (ppb) concentrations of a phosphonate analyte. By combining two channels of NEMS detection with an ultrafast GC front-end, chromatographic analysis of 13 chemicals was performed within a 5 s time window
Genetic analysis of the role of G protein–coupled receptor signaling in electrotaxis
Cells display chemotaxis and electrotaxis by migrating directionally in gradients of specific chemicals or electrical potential. Chemotaxis in Dictyostelium discoideum is mediated by G protein–coupled receptors. The unique Gβ is essential for all chemotactic responses, although different chemoattractants use different receptors and Gα subunits. Dictyostelium amoebae show striking electrotaxis in an applied direct current electric field. Perhaps electrotaxis and chemotaxis share similar signaling mechanisms? Null mutation of Gβ and cAMP receptor 1 and Gα2 did not abolish electrotaxis, although Gβ-null mutations showed suppressed electrotaxis. By contrast, G protein signaling plays an essential role in chemotaxis. G protein–coupled receptor signaling was monitored with PHcrac–green fluorescent protein, which translocates to inositol phospholipids at the leading edge of cells during chemotaxis. There was no intracellular gradient of this protein during electrotaxis. However, F-actin was polymerized at the leading edge of cells during electrotaxis. We conclude that reception and transduction of the electrotaxis signal are largely independent of G protein–coupled receptor signaling and that the pathways driving chemotaxis and electrotaxis intersect downstream of heterotrimeric G proteins to invoke cytoskeletal elements
AAC W1876 hard red spring wheat
AAC W1876 hard red spring wheat (Triticum aestivum L.) has grain yield and time to maturity within the range of the check cultivars: Katepwa, Laura, Lillian, Carberry, and CDC Kernen. AAC W1876 has an awned spike, a low lodging score indicative of strong straw, and a short plant stature typical of a semidwarf wheat. AAC W1876 expressed resistance to prevalent races of leaf rust, moderate resistance to stem rust, intermediate resistance to fusarium head blight, yellow rust, common bunt, and loose smut. Compared to the Canada Western Red Spring check cultivars, AAC W1876 had improved flour yield and lower flour ash. AAC W1876 is eligible for grades of Canada Western Red Spring
The retreat from widening participation? : the National Scholarship Programme and new access agreements in English higher education
This article critically analyses the impact of reforms to the student financial support system in English higher education. Comparative analysis of financial support mechanisms and patterns of outreach engagement with groups underrepresented in higher education show a marked deterioration in the levels of cash support available and an increasingly focus on the brightest poor students (in the form of merit aid) at the expense of the generality of poorer students since the new support programme came into place. This can be seen as part of a wider policy shift away from generic widening participation to the targeting of specific cohorts to raise the attainment level of intakes or to meet recruitment shortfalls. The findings are located in a context of a (near) trebling of tuition fees, stagnation in overall student numbers and the promotion of market mechanisms, all of which can be seen as a challenge to the notion of social justice through the higher education system
AAC Penhold Canada Prairie Spring Red Wheat
AAC Penhold, an awned hard red spring wheat (Triticum aestivum L.) cultivar, yielded significantly more grain than 5700PR while maturing 2 days earlier, and 7.5 cm shorter stature. The seed size was significantly larger than 5700PR and 5701PR, with a test weight significantly heavier than both checks. AAC Penhold expressed resistance to prevalent races of leaf rust and common bunt, and moderate resistance to fusarium head blight and stem rust. AAC Penhold had higher grain and flour protein than the checks and improved Hagberg Falling Number, amylograph viscosity, and water absorption. AAC Penhold is eligible for grades of the market class, Canada Prairie Spring Red wheat
AAC Congress Durum Wheat
Congress durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.) is adapted to the durum production area of the Canadian prairies. Averaged over three years, AAC Congress yielded significantly more grain than Strongfield and AC Navigator. AAC Congress had protein concentration significantly lower than Strongfield but significantly higher than Brigade. AAC Congress is eligible for grades of Canada Western Amber Durum. It has lower grain cadmium concentration and higher yellow pigment concentration than the check cultivars, except AAC Cabri
