The Teaching of Geography in Raywood Elementary School, Raywood, Texas
No full textThe purposes of the writer of this thesis are as follows: 1. To show how man lives, what he does, and why his condition is different, 2. to show the dependence of man upon earth\u27s conditions and earth\u27s resources and, 3. to relate how the writer used the natural resources found in the community to teach geography to the lower Elementary Grades.
The teachers in the rural schools who are alert to the needs of, and the interest of the girls and boys in their classes can find numerous ways of improving their teaching. One of the most important improvement in methods of instruction is the emphasis now placed upon bringing the child into contact with the objects taught. Here-to-fore the sole methods of developing new ideas was by the teacher supplemented by the written words of the text. In either case it was instruction by words. Today however we no longer use this sole avenue of approach, but recognize the value of teaching a new thing by presenting for consideration, whenever possible, first, the word for the thing, second, the thing itself, third, a model of the thing and lastly, a painting or picture of the thing.
Pupils should be taught to observe, and by correlation of nature study and science and brawing, I shall endeavor to show how they can be trained to observe the things about them. Observation will show a child that geography is not a study of words in books, but a study of the world and the things around him.
The writer shall also attempt to familiarize them with the threefold need of man, food, clothing and shelter, of man\u27s relation to community life, how this is influenced by geographical conditions, and what those conditions are. The writer\u27s final point is to show the interdependence of man and the cooperation for the common good, and how man is dependent upon earth\u27s resources for the essential things of life.
The author has attempted to make her class in geography a thing of joy; so many of her pupils were coming to her saying, I just hate geography , that she set about conceiving a plan that would make them enjoy it, for surely if they hated it, they were not getting anything from it, and the time was being wasted. The author has been so entirely successful in the fulfillment of her aim that she is passing her plan on the others who might find themselves faced with the same problems

The bronchodilator response in preschool children: A systematic review
No full textBACKGROUND: The bronchodilator response (BDR) is frequently used to support diagnostic and therapeutic decision-making for children who wheeze. However, there is little evidence-based guidance describing the role of BDR testing in preschool children and it is unclear whether published cut-off values, which are derived from adult data, can be applied to this population. METHODS: We searched MEDLINE, EMBASE, Web of Science, and Cochrane databases (inception-September 2015) for studies reporting response to a bronchodilator in healthy preschool children, response following placebo inhalation, and the diagnostic efficacy of BDR compared with a clinical diagnosis of asthma/recurrent wheezing. FINDINGS: We included 14 studies. Thirteen studies provided BDR data from healthy preschool children. Two studies reported response to placebo in preschool children with asthma/recurrent wheezing. Twelve studies compared BDR measurements from preschool children with asthma/recurrent wheeze to those from healthy children and seven of these studies reported diagnostic efficacy. Significant differences between the BDR measured in healthy preschool children compared with that in children with asthma/recurrent wheeze were demonstrated in some, but not all studies. Techniques such as interrupter resistance, oscillometry, and plethysmography were more consistently successfully completed than spirometry. Between study heterogeneity precluded determination of an optimum technique. INTERPRETATION: There is little evidence to suggest spirometry-based BDR can be used in the clinical assessment of preschool children who wheeze. Further evaluation of simple alternative techniques is required. Future studies should recruit children in whom airways disease is suspected and should evaluate the ability of BDR testing to predict treatment response
Pion absorption in C-12
No full textWe have studied the two reactions 12C(π+,pp) and 12C(π+,ppp) in one experiment, using the CHAOS spectrometer at TRIUMF, at incident pion energies of 200, 240, and 280 MeV. In both cases, we are able to distinguish between reaction mechanisms involving only the detected protons, and those in which additional nucleons must have participated, on the basis of missing momentum. In the case of 12C(π+,ppp), we identify events due to the two step process of π+p quasielastic scattering followed by two-nucleon absorption. Estimates are made for the total cross sections for the various absorption mechanisms
pi pi --> pi pi cross-sections near threshold
No full textAn analysis of new data for the reaction p6p!p6p1n at incident energies between 223 and 284 MeV is
presented. p1p2 cross sections are obtained via Goebel-Chew-Low techniques by extrapolation to the pion
pole using the pseudoperipheral approximation. A consistency check between the present experimental results
and previous experiments at higher energies is made using Roy equations. The isospin 0, S-wave pp scattering
length was obtained using a variety of methods. The result obtained from a threshold expansion is a0 0
50.20460.014 ~statistical! 60.008 ~systematic! in inverse pion mass units. It is shown that there are significant
differences between the reaction mechanisms for the (p2p1) and (p1p1) channels
