Highly Qualified for Successful Teaching: Characteristics Every Teacher Should Possess

This article examines the reflections of university students regarding the characteristics of their favorite teachers from whom they were able to learn. Data collected from the students indicates that there are twelve common characteristics that emerged as central to what students conceptualize as good teaching. Those twelve characteristics connect to the theme of caring for students, both academically and personally and strengthen recent indicators for “highly qualified” teachers. In reviewing effective teacher research, there is a strong link between what students characterize as good teaching and what the research reports as the traits of effective teachers. Awareness of these traits can help preservice teachers and inservice teachers develop qualities that are associated with effective teachers

In situ characterization of vertically oriented carbon nanofibers for three-dimensional nano-electro-mechanical device applications

We have performed mechanical and electrical characterization of individual as-grown, vertically oriented carbon nanofibers (CNFs) using in situ techniques, where such high-aspect-ratio, nanoscale structures are of interest for three-dimensional (3D) electronics, in particular 3D nano-electro-mechanical-systems (NEMS). Nanoindentation and uniaxial compression tests conducted in an in situ nanomechanical instrument, SEMentor, suggest that the CNFs undergo severe bending prior to fracture, which always occurs close to the bottom rather than at the substrate–tube interface, suggesting that the CNFs are well adhered to the substrate. This is also consistent with bending tests on individual tubes which indicated that bending angles as large as ~70° could be accommodated elastically. In situ electrical transport measurements revealed that the CNFs grown on refractory metallic nitride buffer layers were conducting via the sidewalls, whereas those synthesized directly on Si were electrically unsuitable for low-voltage dc NEMS applications. Electrostatic actuation was also demonstrated with a nanoprobe in close proximity to a single CNF and suggests that such structures are attractive for nonvolatile memory applications. Since the magnitude of the actuation voltage is intimately dictated by the physical characteristics of the CNFs, such as diameter and length, we also addressed the ability to tune these parameters, to some extent, by adjusting the plasma-enhanced chemical vapor deposition growth parameters with this bottom-up synthesis approach

Intergenerational Challenges in Teaching & Learning

Complacency and Conformity: The Female Experience at Gettysburg College, 1956-1966

Women at Gettysburg College from 1956-66 received unequal treatment at a predominantly male school. Despite the 1960s being seen as a time of radical change, the majority of women on campus were content with the rules and social norms which held them in place. Changes and complaints were not widespread or outspoken, but they did exist in organizations such as the Women’s Student Government Association. Examinations of campus policies, dress codes, and dorm regulations illustrate the different standards men and women were held to on campus. Meanwhile Greek life, beauty contests, athletics and first hand accounts of social life reveal a complex relationship between the desires of women at that time, and the world in which they lived. Due to such social rules, Gettysburg College remained cocoon-like for many women. As the outside world and politics began to shift, Gettysburg College would continue to cling to old norms until the last few years of the 1960s

Microbial Induction of Immunity, Inflammation, and Cancer

The human microbiota presents a highly active metabolic that influences the state of health of our gastrointestinal tracts as well as our susceptibility to disease. Although much of our initial microbiota is adopted from our mothers, its final composition and diversity is determined by environmental factors. Westernization has significantly altered our microbial function. Extensive experimental and clinical evidence indicates that the westernized diet, rich in animal products and low in complex carbohydrates, plus the overuse of antibiotics and underuse of breastfeeding, leads to a heightened inflammatory potential of the microbiota. Chronic inflammation leads to the expression of certain diseases in genetically predisposed individuals. Antibiotics and a “clean” environment, termed the “hygiene hypothesis,” has been linked to the rise in allergy and inflammatory bowel disease, due to impaired beneficial bacterial exposure and education of the gut immune system, which comprises the largest immune organ within the body. The elevated risk of colon cancer is associated with the suppression of microbial fermentation and butyrate production, as butyrate provides fuel for the mucosa and is anti-inflammatory and anti-proliferative. This article will summarize the work to date highlighting the complicated and dynamic relationship between the gut microbiota and immunity, inflammation and carcinogenesis
