How Much Do You Spend?: Textbook Affordability at Gettysburg College

This poster, created for Musselman Library\u27s Charting your Course 2019 first-year orientation activity, explains some of the strategies that Gettysburg College students can use to mitigate the impacts of rising textbook costs

”Glädje, samhörighet… viss del galenskap”. Förskolepedagogers förhållningssätt till musik, i ljuset av kreativitet och barns delaktighet.

Syftet med detta arbete är att studera musikinriktade förskolor och synliggöra hur pedagogerna tänker kring och arbetar med musik, i ljuset av kreativitet och barns delaktighet. För att besvara vår frågeställning ställer vi oss frågorna hur pedagogerna förhåller sig till kreativitet och barns delaktighet i musicerandet och hur verksamheten påverkas av denna inställning. Vi har alltså fokus på pedagogerna, hur de tänker och arbetar med musik och hur de förhåller sig till barnens musicerande. Pedagogerna som ingår i studien arbetar i barngrupper med barn inom åldersspannet 1-5 år. Vi har intervjuat tre pedagoger på två olika förskolor, samtliga med någon form av musikinriktad verksamhet. Arbetet bygger på empiriskt inhämtad data samt av litteraturstudier. För att samla empirisk data har vi använt oss av intervjuer och observationer. Vi har genom intervjuerna synliggjort pedagogers tankar kring musik i verksamheten. Observationerna har styrkt intervjusvaren och samtidigt gett oss ytterligare stoff som inte har framförts under intervjutillfällena. Resultatet visade att pedagogerna vågade skapa nytt inom musiken och att de var lyhörda för barnens respons och tankar kring musicerandet i verksamheten. Det resulterade i att musiken inte var bunden till samlingen, utan genomsyrade hela verksamheten. Arbetet visar också att musik som språk och uttryckssätt är ett viktigt medel i Läroplanen för förskolan, Lpfö 98, och att pedagogernas förhållningssätt till musik bidrar till att genomföra förskolans uppdrag

2019 Gettysburg College Student Textbook and Course Materials Survey Executive Summary

We’ve all heard stories of students struggling with textbook costs, but how do our students cope when the price gets too high? Modeled after the Student Textbook and Course Materials Survey conducted by Florida Virtual Campus, Musselman Library’s course materials survey sought to uncover how textbook costs impact the success of Gettysburg College students. Results give insight into participants’ perceptions of how much money they spend, the strategies they use to reduce costs, and the effects of the cost of course materials on their academic success. The Executive Summary details our research questions, key findings, and main takeaways

Quantum Hall effect on centimeter scale chemical vapor deposited graphene films

We report observations of well developed half integer quantum Hall effect (QHE) on mono layer graphene films of 7 mm \times 7 mm in size. The graphene films are grown by chemical vapor deposition (CVD) on copper, then transferred to SiO_{2} /Si substrates, with typical carrier mobilities \approx 4000 cm^{2} /Vs. The large size graphene with excellent quality and electronic homogeneity demonstrated in this work is promising for graphene-based quantum Hall resistance standards, and can also facilitate a wide range of experiments on quantum Hall physics of graphene and practical applications exploiting the exceptional properties of graphene

Leptin fails to blunt the lipopolysaccharide-induced activation of the hypothalamic-pituitary-adrenal axis in rats

Copyright @ 2013 The authors. This work is licensed under a Creative Commons Attribution 3.0 Unported License.Obesity is a risk factor for sepsis morbidity and mortality, whereas the hypothalamic-pituitary-adrenal (HPA) axis plays a protective role in the body's defence against sepsis. Sepsis induces a profound systemic immune response and cytokines serve as excellent markers for sepsis as they act as mediators of the immune response. Evidence suggests that the adipokine leptin may play a pathogenic role in sepsis. Mouse endotoxaemic models present with elevated leptin levels and exogenously added leptin increased mortality whereas human septic patients have elevated circulating levels of the soluble leptin receptor (Ob-Re). Evidence suggests that leptin can inhibit the regulation of the HPA axis. Thus, leptin may suppress the HPA axis, impairing its protective role in sepsis.We hypothesised that leptin would attenuate the HPA axis response to sepsis.We investigated the direct effects of an i.p. injection of 2 mg/kg leptin on the HPA axis response to intraperitoneally injected 25 μg/kg lipopolysaccharide (LPS) in the male Wistar rat. We found that LPS potently activated the HPA axis, as shown by significantly increased plasma stress hormones, ACTH and corticosterone, and increased plasma interleukin 1β (IL1β) levels, 2 h after administration. Pre-treatment with leptin, 2 h before LPS administration, did not influence the HPA axis response to LPS. In turn, LPS did not affect plasma leptin levels. Our findings suggest that leptin does not influence HPA function or IL1b secretion in a rat model of LPS-induced sepsis, and thus that leptin is unlikely to be involved in the acute-phase endocrine response to bacterial infection in rats.The section is funded by grants from the MRC, BBSRC, NIHR and an Integrative Mammalian Biology (IMB) Capacity Building Award, and by a FP7-HEALTH-2009-241592 EuroCHIP grant and is supported by the NIHR Imperial Biomedical Research Centre Funding Scheme.

Impact of Sleep and Circadian Disruption on Energy Balance and Diabetes: A Summary of Workshop Discussions

A workshop was held at the National Institute for Diabetes and Digestive and Kidney Diseases with a focus on the impact of sleep and circadian disruption on energy balance and diabetes. The workshop identified a number of key principles for research in this area and a number of specific opportunities. Studies in this area would be facilitated by active collaboration between investigators in sleep/circadian research and investigators in metabolism/diabetes. There is a need to translate the elegant findings from basic research into improving the metabolic health of the American public. There is also a need for investigators studying the impact of sleep/circadian disruption in humans to move beyond measurements of insulin and glucose and conduct more in-depth phenotyping. There is also a need for the assessments of sleep and circadian rhythms as well as assessments for sleep-disordered breathing to be incorporated into all ongoing cohort studies related to diabetes risk. Studies in humans need to complement the elegant short-term laboratory-based human studies of simulated short sleep and shift work etc. with studies in subjects in the general population with these disorders. It is conceivable that chronic adaptations occur, and if so, the mechanisms by which they occur needs to be identified and understood. Particular areas of opportunity that are ready for translation are studies to address whether CPAP treatment of patients with pre-diabetes and obstructive sleep apnea (OSA) prevents or delays the onset of diabetes and whether temporal restricted feeding has the same impact on obesity rates in humans as it does in mice
