Learning How to Learn: Incorporating Metacognition in the Business Writing Classroom
Teaching business writing in the university can be done with both the use of technology and also with handwritten in-class assignments. This presentation will explain how using computers plus incorporating the old-fashioned handwritten in-class assignment is a more effective way to develop the students’ metacognitive skills
Beyond Composition: Teaching Students How to Transition from Composition Classes to the Business Writing Classes
Students often fail to apply writing skills learned from course to course. This presentation will address the transfer of students’ writing skills from two perspectives: the first-year composition instructor and the business writing instructor. Instructors can benefit from a dialogue on bridging the gap between courses
What is a planet?
A planet is an end product of disk accretion around a primary star or
substar. I quantify this definition by the degree to which a body dominates the
other masses that share its orbital zone. Theoretical and observational
measures of dynamical dominance reveal a gap of four to five orders of
magnitude separating the eight planets of our solar system from the populations
of asteroids and comets. The proposed definition dispenses with upper and lower
mass limits for a planet. It reflects the tendency of disk evolution in a
mature system to produce a small number of relatively large bodies (planets) in
non-intersecting or resonant orbits, which prevent collisions between them.Comment: 22 pages, 3 tables, 4 figures, published in Astronomical Journal 132,

Urticaria and Arthralgias as Manifestations of Necrotizing Angiitis (Vasculitis)**From the Departments of Dermatology and Medicine. Harvard Medical School, and the Division of Dermatology, Departments of Medicine, Peter Bent Brigham and Robert B. Brigham Hospitals. Boston, Massachusetts. (Reprint requests to: Dr. Soter, Robert B. Brigham Hospital, 125 Parker Hill Avenue, Boston, Mass. 02120.)
Although necrotizing angiitis (vasculitis) of the superficial venules and capillaries of the skin is usually appreciated visually as a purpuric papule, a group of patients has been defined in whom all of the skin lesions were urticarial. Microscopic examination of skin biopsy specimens showed fibrinoid necrosis of the blood-vessel walls, an infiltrate containing polymorphonuclear leukocytes, fragmentation of cell nuclei, and extravasation of erythrocytes. Arthralgias were present in 7 of the 8 patients and arthritis in 3 of these. Two of the patients experienced episodes of abdominal pain. A syndrome of chronic refractory urticaria accompanied by arthralgias and occasionally arthritis or abdominal pain and an elevated erythrocyte sedimentation rate was recognized in nonatopic female patients and appears to be a manifestation of an underlying necrotizing angiitis
Environmental Analysis of Cores from the Helike Delta, Gulf of Corinth, Greece
The fan delta southeast of Aigion on the southwest shore of the Gulf of Corinth was the site of ancient Helike, a city destroyed and submerged by an earthquake and seismic sea wave in 373 BC. Bore holes drilled on the Helike Delta yielded numerous ceramic fragments in the upper 12 meters, and a record of changing local environments on the delta during the Holocene period. At about 8 m below present sea level the core profiles show a general upward transition from marine to lacustrine/lagoonalc onditions.T he transition dates from about 8 kyr BP and is probably due to the deceleration of global sea level rise at the end of the last Ice Age. The deceleration apparently induced an upward and seaward progression of a zone of green clay and silt associated with brackish fauna
Irradiação de micro-ondas aplicada Ă sĂntese orgânica: uma histĂłria de sucesso no Brasil
This review article shows the publications in the field of microwave irradiation published by Brazilian researchers over the past 10 years. In South America, Brazil leads the publication of articles with the use of microwave irradiation possessing a large advantage in number of articles published over the others countries. The works were divided into four major areas: Catalysis, Reactions without Solvent, Heterocycles Chemistry, Natural Products and Other, and some could be classified in more than one category
