A diffraction grating is a plane surface having a large number of closely spaced slits running in parallel. When light of appropriate wavelength is incident on a diffraction grating it functions as a spectrometer, able to separate the light into its spectral components. Physical examples of interest for diffraction in the real world are…

This study investigated the levels of training law enforcement officers (LEOs) receive regarding mental illness, developmental/cognitive delays, schizophrenia, or an autism spectrum disorder. Coleman and Cotton (2014) stated that there is a need for LEOs to be knowledgeable on the signs and symptoms of mental illness and interventions that are…

Purpose: This study aims to explore students' sustainability attitudes and behavioural intentions and their relation to energy use, to promote energy saving and decarbonisation in higher education settings. Design/methodology/approach: The authors used a validated energy literacy survey to assess undergraduate students' attitudes and behavioural…

The separation of chamazulene from hydrophilic contaminants present in blue tansy oil provides a visually engaging example of two common techniques: extraction and thin-layer chromatography (TLC). This application uses liquid CO[subscript 2] as a lipophilic solvent to pull a brilliant blue hydrocarbon molecule, chamazulene, out of or through a…

Academic research is increasingly driven by research assessment exercises (in the UK, by the Research Excellence Framework, REF). These aim to compare outputs of researchers in each university with those elsewhere, but evaluation efforts have suffered from widespread criticism. The status of pedagogic research in higher education (HE)--once…

In Fall 2014 the University of Maryland Libraries launched a textbook reserves program to help relieve the burden of high textbook costs on students. Although its initial performance was lackluster, workflow refinements and expanded promotion greatly improved usage, resulting in a tenfold increase in circulation and expansion of the program. This…

Purpose: The purpose of this paper is to examine the effect of intensive extra-curricular learning opportunities on students' knowledge, skills, and attitudes regarding cotton and sustainability. Design/methodology/approach: A three-phase extra-curricular learning opportunity was designed to include a Sustainable Cotton Summit; pre-summit and…

Objectives: To synthesize and review pedagogically informed interventions that increase nutrition knowledge and decrease weight prejudice among practicing and pre-service health and education professionals. These factors have been addressed as separate entities in intervention-based research and this represents a gap in current literature. The…

The founder of TOMS Shoes, Blake Mycoskie, and the late Apple cofounder and CEO, Steve Jobs, model the role of passion and purpose in leader developmental readiness.

The correct use of micropipettes has been investigated in an undergraduate, introductory lab experiment intended for chemistry and biology majors. This lab experiment involves the use of micropipettes for accurately mixing, transferring, and applying a specific amount of dye to a cotton bandana. The data resulting from this experiment is a color…

There is considerable literature on internationalising the curriculum in higher education, but relatively little of this focuses on developing international perspectives in home-based students. In particular, there has been limited direct engagement with student views and understandings, especially comparatively across a wide range of subjects. To…

Like many other countries in the world, South Africa is going through a process of transformation (with a high focus on gender transformation). After existing under an oppressive apartheid regime that rendered many people as second-class citizens for decades, most South Africans are seeking ways to move forward and make meaning of their newly…

This goal of this study was to develop a measure that captures the three dimensions of youth purpose proposed by Damon, Menon, and Cotton-Bronk (2003). We tested a theoretical model that links youth purpose (comprised of intention, engagement, and prosocial reasoning) with achievement motivation, agency, and civic engagement for a sample of high…

We think with several theoretical concepts from Jacques Derrida (defer, différance, deconstruction, and trace), in order to better understand how the processes of children, materials, and a teacher (re)defined and (re)imagined writing when they began to compose with a range of tools as writers in a second grade (7- to 8-year-olds) Writers' Studio.…

This study sought to uncover teacher perceptions of social capital within a high school mathematics department utilizing a research design that acknowledged the complex environment faced by high school teachers and their subsequent interpretations of how and from whom they sought access to professional resources. Through an analysis of narratives…
