Place, Prestige, Price, and Promotion: How International Students Use Social Networks To Learn About Universities Abroad

This qualitative study aims to explore the social media component of international student’s college choice process for studying abroad.  One of the emerging evidence was that participants applied social media specific criteria, such as the number of “likes”, the number of followers, and the ratio of followers to following to rank Higher Education Institutions (HEI) and measure their prestige.  Another emerging finding was that participants with no connections abroad relied exclusively on social media for their college choice decisions and without social media would not even consider an option of transferring abroad.   Videos and pictures offered by social network sites (SNS) provided emotional benefits by helping “to see” an unknown reality, develop sense of belonging, diminish apprehensions of moving abroad, and solidify the choice of HEI, while traditional sources of promotion, such as websites, were perceived as not trustworthy. Higher education professionals could hire individuals with proven expertise in social media to create consistent and meaningful content on different social media platforms to connect with potential international candidates.   

Performance-Based Funding of Higher Education: Analyses of Policy Discourse Across Four Case Studies

Performance-based funding (PBF) for public colleges and universities is increasingly prevalent worldwide, as a part of a broader pattern of marketisation in public education. This study focused on developing an empirical view of how, and in what contexts, policy makers use the concepts of neoliberal economics to design and support PerformanceBased Funding (PBF) policies in higher education. We analysed 121 policy documents, white papers, evaluation reports, and news items related to PBF policies in four case jurisdictions: Tennessee, Washington, United Kingdom, and Italy. We employed critical discourse analysis methods as framed by Fairclough and colleagues and implemented this approach within the broader methodological guidance of Carspecken’s critical qualitative research. Grounded in social theory, this study illuminates the role PBF policies play internationally in moving higher education institutions closer to markets. Moreover, it provides an empirical view of the mechanisms and networks built into PBF policy debates. Finally, it contributes to a theoretically and empirically grounded view on the discursive uses of neoliberalism in education policy

Vasoconstrictor and Dilator Responses to Neurokinin a in Isolated Guinea Pig Heart

Effects of neurokinin A (NKA) and substance P (SP) on coronary resistance vessels were studied in isolated guinea pig hearts perfused with isotonic buffer containing 20 mM KCl. Injections of NKA and SP caused dose-dependent reductions in perfusion pressure with ED50 values of 14.0 and 0.326 pmol, respectively. Blockade of nitric oxide synthesis or removal of the endothelium inhibited vasodilator responses to neurokinins. Infusions of NKA or SP caused tachyphylaxis and cross-desensitization to the other neurokinin but not to acetylcholine. Injections of 2.5 nmol NKA increased perfusion pressure by 31 ± 8% when given after tachyphylaxis developed to infused SP (2.5 nmol/100 μl/min). It was concluded that 1) neurokinins cause an endothelium-dependent relaxation of coronary resistance vessels by stimulating NK-1 receptors on endothelial cells, and 2) desensitization of the receptor mediating vasodilation unmasks a vasoconstrictor response to NKA

Hormone-dependent dissociation of blood flow and secretion rate in the lingual salt glands of the estuarine crocodile, Crocodylus porosus

Salt and water balance in the estuarine crocodile, Crocodylus porosus, involves the coordinated action of both renal and extra-renal tissues. The highly vascularised, lingual salt glands of C. porosus excrete a concentrated sodium chloride solution. In the present study, we examined the in vivo actions of vasoactive intestinal peptide (VIP), B-type natriuretic peptide (BNP) and angiotensin II (ANG II) on the secretion rate and blood perfusion of the lingual salt glands. These peptides were selected for their vasoactive properties in addition to their reported actions on salt gland activity in birds and turtles and rectal gland activity in elasmobranchs. The femoral artery was cannulated in seven juvenile crocodiles for delivery of peptides and measurement of mean blood pressure and heart rate. In addition, secretion rate of, and blood flow to, the salt glands were recorded simultaneously using laser Doppler flowmetry. VIP stimulated salt secretion was coupled to an increase in blood flow and vascular conductance of the lingual salt glands. BNP was a potent stimulant of salt gland secretion, resulting in a maximal secretion rate of more than 15-fold higher than baseline; however, this was not coupled to an increase in perfusion rate, which remained unchanged. ANG II failed to stimulate salt gland secretion and there was a transient decrease in salt gland blood flow and vascular conductance. It is evident from this study that blood flow to, and secretion rate from, the lingual salt glands of C. porosus are regulated independently; indeed, it is apparent that maximal secretion from the salt glands may not require maximal blood flow
