Typical delay determines waiting time on periodic-food schedules: Static and dynamic tests.

Pigeons and other animals soon learn to wait (pause) after food delivery on periodic-food schedules before resuming the food-rewarded response. Under most conditions the steady-state duration of the average waiting time, t, is a linear function of the typical interfood interval. We describe three experiments designed to explore the limits of this process. In all experiments, t was associated with one key color and the subsequent food delay, T, with another. In the first experiment, we compared the relation between t (waiting time) and T (food delay) under two conditions: when T was held constant, and when T was an inverse function of t. The pigeons could maximize the rate of food delivery under the first condition by setting t to a consistently short value; optimal behavior under the second condition required a linear relation with unit slope between t and T. Despite this difference in optimal policy, the pigeons in both cases showed the same linear relation, with slope less than one, between t and T. This result was confirmed in a second parametric experiment that added a third condition, in which T + t was held constant. Linear waiting appears to be an obligatory rule for pigeons. In a third experiment we arranged for a multiplicative relation between t and T (positive feedback), and produced either very short or very long waiting times as predicted by a quasi-dynamic model in which waiting time is strongly determined by the just-preceding food delay.

Dr. Stuart D. Scott Papers, 1837-2010 (non-inclusive)

Dr. Stuart D. Scott has written extensively in the fields of prehistory and history. As an archaeologist, he has traveled to some of the most significant sites in the world, including Pompeii, Stonehenge, the Valley of the Kings, Egypt’s pyramids and the Taj Mahal. He spent nine months excavating with the Tikal Project in Guatemala before returning to the University of Arizona where he received a Ph.D. in 1963. He excavated in New Zealand as a Fulbright scholar in 1963-1964. In the fall of 1964, Dr. Scott started a long career in the Anthropology Department of the State University of New York. He taught graduate and undergraduate archaeology courses and continued his archaeological and historical research. In 1979, Scott established the Old Fort Niagara Archaeology in Progress Project at Old Fort Niagara in Youngstown, New York. For many years, he became involved with historical archaeology in western New York. It was during this work that he became interested in the Upper Canada Rebellion of 1837-1838 and its aftermath. Dr. Scott and his wife, Patricia Kay Scott, would use Christmas breaks, summer vacations, and sabbatical years to travel. They were repeatedly lured back to the South Pacific, conducting research in New Zealand, Australia and many of the Micronesian and Polynesian islands. To tell the whole story of the Rebellion and the prison exiles, they traveled extensively in Canada, the United States, England and Tasmania to collect archival research and to experience the scenes of this remarkable narrative. In 2004, Dr. Scott published To the Outskirts of Habitable Creation: Americans and Canadians Transported to Tasmania in the 1840s, which told the story of the men captured, tried, convicted, and exiled as a result of the Rebellion, also called the Patriot War. Other contributions include: • A collaboration with Dr. Charles Cazeau on the book Exploring the Unknown, Great Mysteries Reexamined published by Plenum Press in 1979 • The Patriot Game: New Yorkers and the Canadian Rebellion of 1837-1838, which appeared in New York History, Vol. 68, No.3. 1987 • A Frontier Spirit: The Life of James Gemmell published in Australiasian Canadian Studies, Vol. 25, No. 2 2007 • To the Outskirts of Habitable Creation which appeared in the Friends of the National Archives, Vol. 20, No. 1 2009 • Numerous academic journal publications • Service on conference panels • Various research papers and proposals Before retiring in 1997 and while still a resident of Buffalo, N.Y., Dr. Scott spent considerable time with Brock University President Emeritus James A. Gibson and History Professor Colin Duquemin. The three shared a love of Rebellion history. It was largely because of this connection that Brock University was chosen as the recipient of Dr. Scott’s research materials.

Two-degree-of-freedom vortex-induced vibration of circular cylinders with very low aspect ratio and small mass ratio

The investigation of vortex-induced vibration on very short cylinders with two degrees of freedom has drawn the attention of a large number of researchers. Some investigations on such a problem are carried out in order to have a better understanding of the physics involved in vortex-induced motions of floating bodies such as offshore platforms. In this paper, experiments were carried out in a recirculating water channel over the range of Reynolds number 6000

One and two degrees-of-freedom Vortex-Induced Vibration experiments with yawed cylinders

Vortex-Induced Vibration (VIV) experiments were carried out with yawed cylinders. The purpose was to investigate the validity of the Independence Principle (IP) for properly describing the flow characteristics and the dynamics of structures subjected to oblique flow. Five yaw angles in relation to the direction perpendicular to the free stream velocity were tested, namely View the MathML sourceθ=0°,10°,20°,30° and 45°. Both the upstream and downstream orientations were tested. The models were mounted on a leaf spring apparatus that allows experiments with one or two degrees of freedom. The Reynolds numbers based on the component normal to the cylinder axis fell in the interval 3×103

Just a Tea Stall Girl: Lessons from India

This article charts the learning of a female academic who travelled and volunteered in southern India during a sabbatical leave from her university. Opportunities to discover gender, race and class connections ranged from tea-stall conversations to academic symposia; from outings with impoverished Indian families to excursions with social justice organizations. The author explores topics that include dowry, politics, globalization, communalism, and poverty. To illustrate her learning, she draws on the work of such renowned Indian scholars as Ali Ashgar Engineer and Vandana Shiva.

Hazel McDaniel Teabeau

Hazel McDaniel Teabeau was born in Arkansas in 1892, and she received her BA in English from the University of Kansas in 1915. Her interest in social causes and concern for civil rights are prevalent in her accomplishments. In 1937, she joined the Lincoln University English Department faculty, where she taught for twenty years. While on sabbatical from Lincoln University, Teabeau became the first black woman to enroll at the University of Missouri. She enrolled there at the age of 57 to seek a PhD in Speech and Dramatics, and in 1959 she became the first black woman to receive a doctorate from the University of Missouri.

Omics for Investigating Chitosan as an Antifungal and Gene Modulator

Chitosan is a biopolymer with a wide range of applications. The use of chitosan in clinical medicine to control infections by fungal pathogens such as Candida spp. is one of its most promising applications in view of the reduced number of antifungals available. Chitosan increases intracellular oxidative stress, then permeabilizes the plasma membrane of sensitive filamentous fungus Neurospora crassa and yeast. Transcriptomics reveals plasma membrane homeostasis and oxidative metabolism genes as key players in the response of fungi to chitosan. A lipase and a monosaccharide transporter, both inner plasma membrane proteins, and a glutathione transferase are main chitosan targets in N. crassa. Biocontrol fungi such as Pochonia chlamydosporia have a low content of polyunsaturated free fatty acids in their plasma membranes and are resistant to chitosan. Genome sequencing of P. chlamydosporia reveals a wide gene machinery to degrade and assimilate chitosan. Chitosan increases P. chlamydosporia sporulation and enhances parasitism of plant parasitic nematodes by the fungus. Omics studies allow understanding the mode of action of chitosan and help its development as an antifungal and gene modulator.

O MISTICISMO JUDAICO E APOCALÍPTICO NO APOCALIPSE DE JOÃO CAPÍTULOS 4 E 5 ASCENSÃO E VIAGEM CELESTIAL NO CRISTIANISMO PRIMITIVO

Esta dissertação tem por objeto analisar os textos do livro do Apocalipse capítulos 4 e 5. As fontes de pesquisa pertencem às tradições do Misticismo Judaico. Esta linha, hoje ecoa em estudos do misticismo apocalíptico e do êxtase visionário relativo ao contexto do judaísmo e cristianismo primitivos, em autores tais como: Christopher Rowland, Alan Segal, C. R. A. Morray-Jones e John Ashton, John Collins, Adella Collins, Jonas Machado, Paulo A. S. Nogueira, Carol Newsom, David E. Aune, Philip Alexander, Crispin H.T. Fletcher-Louis, Florentino García Martínez dentre outros; sendo que, estes autores se alinham aos resultados das pesquisas iniciais de Gershom Scholem sobre o Misticismo Judaico, e aos desenvolvimentos mais recentes neste âmbito. Nogueira1 menciona que foi Scholem quem realmente usou este misticismo para produzir a chave das histórias de ascensão celestial presentes nos apocalipses dos últimos dois séculos a.C. e dos primeiros dois séculos d.C. Foi Scholem, na verdade, quem iniciou a discussão acadêmica dos místicos judaicos em seu livro Major Trends in Jewish Myticism - Principais Tendências no Misticismo Judaico em 1941. Corroborando com a tradição destes estudos se encontram as descobertas dos manuscritos de Qumran, como a dos Cânticos do Sacrifício Sabático, uma composição de treze cânticos, também chamada de liturgia angélica, e que tem contribuído para o desenvolvimento das pesquisas, bem como sustentado os argumentos de Scholem. Dentre os manuscritos de Qumran há um fragmento de hinos denominado 4Q405, que trouxe ao conhecimento a terminologia Merkaváh, em que anjos louvam a imagem do Trono da Carruagem citado no primeiro capítulo do livro de Ezequiel. Identificou-se nestes o sincretismo da comunidade de Qumran acerca do canto dos anjos com outras ideias sobre os deveres dos mesmos, sendo uma característica comum às tradições da Ma asseh Merkaváh - (Trabalhos do Divino Trono/Carruagem). 1 NOGUEIRA, Sebastiana M. Silva. 2 Coríntios 12 e o Misticismo Judaico (Os Quatro que Entraram no Pardes). Oracula, 2012 p.04. Assim, a pesquisa segue os pressupostos de Rowland2, de que os textos do Apocalipse 4 e 5 possuem em sua narrativa uma semelhança básica com a liturgia descrita nas tradições do misticismo apocalíptico do judaísmo no I século, bem como em textos de Qumran, principalmente no fragmento 4Q405. Conforme Nogueira3 Ezequiel capítulo 1 é considerado chave desta tradição mística do judaísmo, sendo, também um elemento central do Apocalipse de João, o principal visionário do cristianismo. Assim, a pesquisa inclui a aproximação dos textos considerados fundantes, sendo: (Isaías 6; Ezequiel 1; Daniel 7; I Enoque 14), junto aos textos de Qumran, como o complexo dos 13 Cânticos Sábaticos relacionados ao culto no santuário celestial. A apocalíptica pode ser assim compreendida como um tipo de literatura mística, cujas imagens se conjecturam nos escritos que, por meio da ascensão do visionário aos céus e a contemplação do trono de Deus, descortinam uma determinada tradição do judaísmo antigo. Desta forma podemos também interpretar os capítulos 4 e 5 do Apocalipse como texto místico, de conteúdos similares aos dos textos apocalípticos judaicos, e talvez até com um tipo de experiência religiosa análoga.
