Comparing Comets

This exercise allows students to compare and contrast the nucleus of two comets and listen to audio files of NASA scientists and middle-school students conducting the activity. The imagery and data are authentic and related to real-world science that is currently underway. By comparing their responses to those of NASA scientists, students realize that while their vocabulary may be different, their process parallels that of the scientists and the task of doing science is well within their reach. The teacher's guide is available here: http://epoxi.umd.edu/pdfs/Comparing_Comets_TG.pdf Audio files for the activity can be found here: http://epoxi.umd.edu/3gallery/aud_compcomets.shtml Educational levels: Middle school, Middle school, High school, High school

Proceedings of the I International Meeting In Exercise Physiology

This meeting is the seventh in Exercise Physiology and the first International Workshop in Exercise Physiology of UFSCar, sponsored by the Exercise Physiology Laboratory, Department of Physiological Sciences – DCF, which is affiliated to the Post-Graduation Program in Physiological Sciences (PPGCFS/UFSCar). The event is designed to bring Brazilian scientists, especially from São Paulo state that work with Exercise Physiology and Health. The main objective is to put together these students and scientists interested in developing joint researches in this area. The general theme is Exercise Physiology, including athletic performance, nutrition and metabolism. Therefore, the central roundtable programmed in this year is “Physical Activity and Health” with three foreign speakers, from Spain and United States

Selective Realism vs. Individual Realism for Scientific Creativity

Individual realism asserts that our best scientific theories are (approximately) true. In contrast, selective realism asserts that only the stable posits of our best scientific theories are true. Hence, individual realism recommends that we accept more of what our best scientific theories say about the world than selective realism does. The more scientists believe what their theories say about the world, the more they are motivated to exercise their imaginations and think up new theories and experiments. Therefore, individual realism better fosters scientific creativity than selective realism

Expanding sensor networks to automate knowledge acquisition

The availability of accurate, low-cost sensors to scientists has resulted in widespread deployment in a variety of sporting and health environments. The sensor data output is often in a raw, proprietary or unstructured format. As a result, it is often difficult to query multiple sensors for complex properties or actions. In our research, we deploy a heterogeneous sensor network to detect the various biological and physiological properties in athletes during training activities. The goal for exercise physiologists is to quickly identify key intervals in exercise such as moments of stress or fatigue. This is not currently possible because of low level sensors and a lack of query language support. Thus, our motivation is to expand the sensor network with a contextual layer that enriches raw sensor data, so that it can be exploited by a high level query language. To achieve this, the domain expert specifies events in a tradiational event-condition-action format to deliver the required contextual enrichment

Commodity culture : tropical health and hygiene in the British Empire

Before heading to a 'tropical' region of the Empire, British men and women spent considerable time and effort gathering outfit believed essential for their impending trip. Ordinary items such as soap, clothing, foodstuffs and bedding became transformed into potentially life-saving items that required the fastidious attention of any would-be traveller. Everyone from scientists and physicians to missionaries and administrators was bombarded by relentless advertising and abundant advice about the outfit needed to preserve health in a tropical climate. A closer look at this marketing exercise reveals much about the way people thought about tropical people, places, health and hygiene and how scientific and commercial influences shaped this Imperial commodity culture

Writing biology with mutant mice: the monstrous potential of post genomic life

Social scientific accounts identified in the biological grammars of early genomics a monstrous reductionism, ‘an example of brute life, the minimalist essence of things’ (Rabinow, 1996, p. 89). Concern about this reductionism focused particularly on its links to modernist notions of control; the possibility of calculating, predicting and intervening in the biological futures of individuals and populations. Yet, the trajectories of the post genomic sciences have not unfolded in this way, challenging scientists involved in the production and integration of complex biological data and the interpretative strategies of social scientists honed in critiquing this reductionism. The post genomic sciences are now proliferating points from which to understand relations in biology, between genes and environments, as well as between species and spaces, opening up future possibilities and different ways of thinking about life. This paper explores the emerging topologies and temporalities of one form of post genomic research, drawing upon ethnographic research on international efforts in functional genomics, which are using mutant mice to understand mammalian gene function. Using vocabularies on the monstrous from Derrida and Haraway, I suggest an alternative conceptualisation of monstrosity within biology, in which the ascendancy of mice in functional genomics acts as a constant supplement to the reductionist grammars of genomics. Rather than searching for the minimalist essence of things, this form of functional genomics has become an exercise in the production and organization of biological surplus and excess, which is experimental, corporeal and affective. The uncertain functioning of monsters in this contexts acts as a generative catalyst for scientists and social scientists, proliferating perspectives from which to listen to and engage with the mutating landscapes, forms of life, and languages of a post genomic biology

Diagnostic studies of the HxOy-NzOy-O3 photochemical system using data from NASA GTE field expeditions

Spring 1084 GTE CITE-1 flight data from the field exercise was obtained from a GTE Data Archive Tape. Chemical and supporting meteorological data taken over the Pacific Ocean was statistically and diagnostically analyzed to identify the key processes affecting the concentrations of ozone and its chemical precursors in the region. The analysis was completed. The analysis of the GTE CITE-2 data is being performed in collaboration with Dr. D.D. Davis and other GTE scientists. Initial results of the analysis were presented and work begun on the paper describing the results
