Since 1995 engineering faculty at Hope College have taught a course for non-engineering students called: "Science and Technology of Everyday Life" The course examines the science and engineering underlying modern consumer technological devices. Distinguishing features are study of a broad sample of familiar technological devices, construction by students of working devices, and writing assignments on technological topics. Over nine years, the total enrollment of more than 1000 students has averaged 60% women and 26% pre-service teachers. To evaluate student outcomes, the Motivated Strategies for Learning Questionnaire (MSLQ) was applied. Statistically significant increases were found in intrinsic motivation, task value, and self-efficacy. A decrease in test anxiety was also found. The results are consistent across all semesters analyzed. The case study shows that non-engineering students can have increased motivation for learning science and technology, increased perceived value for science and technology, increased self-confidence about learning science and technology.
We present a 9-day-old girl with multifocal cutaneous and hepatic infantile hemangiomas as well as a hepatic rapidly involuting congenital hemangioma. These two distinct vascular tumors have rarely been reported to co-occur. We additionally review the sonographic features that distinguish a hepatic congenital hemangioma from the hepatic infantile hemangioma.
Understanding the effects of age on the epidemiology of diseases primarily affecting the skin is important to the practice of dermatology, both for proper allocation of resources and for optimal patient-centered care. To fully appreciate the effect that age may have on the population-based calculations of incidence of diseases primarily affecting the skin in Olmsted County, Minnesota, and worldwide, we performed a review of all relevant Rochester Epidemiology Project-published data and compared them to similar reports in the worldwide English literature. Using the Rochester Epidemiology Project, population-based epidemiologic studies have been performed to estimate the incidence of specific skin diseases over the past 50 years. In older persons (>65 years), nonmelanoma skin cancer, lentigo maligna, herpes zoster, delusional infestation, venous stasis syndrome, venous ulcer, and burning mouth syndrome were more commonly diagnosed. In those younger than 65 years, atypical nevi, psoriatic arthritis, pityriasis rosea, herpes progenitalis, genital warts, alopecia areata, hidradenitis suppurativa, infantile hemangioma, Behçet's disease, and sarcoidosis (isolated cutaneous, with sarcoidosis-specific cutaneous lesions and with erythema nodosum) had a higher incidence. Many of the incidence rates by age group of diseases primarily affecting the skin derived from the Rochester Epidemiology Project were similar to those reported elsewhere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
