When solving systems of equations by using matrices, many teachers present a Gauss-Jordan elimination approach to row reducing matrices that can involve painfully tedious operations with fractions (which I will call the traditional method). In this essay, I present an alternative method to row reduce matrices that does not introduce additional fractions until the very last steps. The students i...

Classic psychology and economic studies argue that punishment is the standard response to violations of fairness norms. Typically, individuals are presented with the option to punish the transgressor or not. However, such a narrow choice set may fail to capture stronger alternative preferences for restoring justice. Here we show, in contrast to the majority of findings on social punishment, tha...

Social media brand communities have been widely adopted by marketers as a marketing channel to engage consumers, and by consumers as a source of product/brand information prior to their purchase decisions. The popularity of social media brand communities has attracted some academic research efforts. However, there still exist important research gaps to be addressed in the existing literature. F...

The present study investigates syntactic priming with children aged three and four. It examines whether children can be primed to use two alternative complex noun phrases (an adjective+noun structure and a noun+relative clause construction) to describe pictures, how susceptible children are to priming (in comparison to adult subjects) and which of the two alternative phrases is preferred accord...

Background The performance of TVS, TRS and MRI for the diagnosis of DIE have been separately reported in earlier studies. However, the three methods have not been concurrently compared in terms of their overall performance and classified results as per different anatomical locations of DIE lesions in a large study population. This study was an attempt to compare pelvic magnetic resonance imagin...

Key Data Findings. (1) From March 2012 to March 2013, rural enrollment in Medicare Advantage (MA) and other prepaid plans increased by over 200,000 enrollees, to more than 1.9 million. (2) Preferred provider organization (PPO) plan enrollment increased to nearly one million enrollees, accounting for more than 51% of the rural MA market (up from 48% in March 2012). (3) Health maintenance organiz...

NHS Blackburn with Darwen Provider Services Unit has adopted an innovative team approach to improve patient access to its community matron service. This article reviews the national picture and local development of the community matrons role.

With the increased complexity of ontologies, building and using large-scale ontologies require cooperative and scalable mechanisms. In this paper, we propose a modular ontology approach for such challenge. A large ontology has multiple smaller modules called packages, which are sets of highly related terms and term relations; packages can be nested in other packages, forming a package hierarchy...

Placement in prestigious research institutions for STEM (science, technology, engineering, and mathematics) PhD recipients is generally considered to be optimal. Yet some doctoral recipients are not interested in intensive research careers and instead seek alternative careers, outside but also within academe (for example teaching positions in Liberal Arts Schools). Recent attention to non-acade...
