All Hands on Deck: Instructors as Collaborators and the Modified Dynamics of Design Build Interaction

In beginning architectural education, design-build studios offer uniquely challenging, but beneficial, learning opportunities. Because of the elevated expectation that the studio activities will conclude with an occupied environment designed and built primarily by students, students and instructors have to bear new responsibilities and apply a broader range of skills towards the project. These new responsibilities require responsive pedagogical adjustments

The geometry of reaction norms yields insights on classical fitness functions for Great Lakes salmon.

Life history theory examines how characteristics of organisms, such as age and size at maturity, may vary through natural selection as evolutionary responses that optimize fitness. Here we ask how predictions of age and size at maturity differ for the three classical fitness functions-intrinsic rate of natural increase r, net reproductive rate R0, and reproductive value Vx-for semelparous species. We show that different choices of fitness functions can lead to very different predictions of species behavior. In one's efforts to understand an organism's behavior and to develop effective conservation and management policies, the choice of fitness function matters. The central ingredient of our approach is the maturation reaction norm (MRN), which describes how optimal age and size at maturation vary with growth rate or mortality rate. We develop a practical geometric construction of MRNs that allows us to include different growth functions (linear growth and nonlinear von Bertalanffy growth in length) and develop two-dimensional MRNs useful for quantifying growth-mortality trade-offs. We relate our approach to Beverton-Holt life history invariants and to the Stearns-Koella categorization of MRNs. We conclude with a detailed discussion of life history parameters for Great Lakes Chinook Salmon and demonstrate that age and size at maturity are consistent with predictions using R0 (but not r or Vx) as the underlying fitness function

The Rosary (Le Rosaire, Der Rosenkranz)

Arrangement for solo mezzo-soprano or baritone voice with piano accompaniment of Ethelbert Nevin\u27s popular hymn The Rosary, with French and German translations of the lyrics. The lyrics were written by Robert Cameron Rogers, with the French translation by C. Eschig and German translation by Carl Engel. The song premiered in 1898. By 1928 it had sold over 2.6 million copies, making it one of the best selling pieces of sheet music of the period.https://ecommons.udayton.edu/imri_sheetmusic/1074/thumbnail.jp

Joint repair methods for cast iron natural gas distribution mains and the preliminary development of an alternative joint seal.

Approximately 10 percent of the natural gas pumped into distribution systems is unaccounted for. A significant portion of this amount is leakage from joints in 50 to 100 year old cast iron main. Because of the cumulative effects of many small leaks, these leaks must be repaired even though the repair expense is not always justified by the value of the gas conserved.Part One identifies and evaluates leak sealing techniques of the past and present by compiling available test data. A major task was to review all documented test results in journals and technical reports. This study followed-up on published articles by contacting all the individuals and organizations concerned. Recommendations for future development of an alternate sealing system are made.Part Two discusses preliminary criteria for the design of an alternative system to seal main joints from within the main without service interruption. Experiments were performed showing that very soft elastomers pressed against the rough pipe wall could prohibit leakage. Potential cleaning methods were tested. Wire and abrasive wheels, and water-jets were recommended for further development. Based on time-dependent characteristics and resistance to aging and to chemicals found in mains, fluorocarbon was recommended for use as the seal material. Preliminary design of the seal verified its feasibility. Several innovative concepts for the seal are presented. Considerations for the cleaning and sealing device and for the overal'. system are discussed

Review of Freedom to Learn

L’oeuvre de Carl R. Rogers, « Liberté pour apprendre », a partir de questions sur le système d’éducation. Il a ecrit aux professionels de l’éducation dans une tentative de motiver le desire de changement et la réalisation de quelque chose de concret. Pour cela, Carl met à la disposition tout ce qu’il a pu voir d’utile dans sa propre expérience. Il offre des exemples qui montrent de quel manière des professeurs, qui travaillent à différents niveaux d’enseignement, ont découvert des maniéres de proportionner la liberté pour apprendre, et l´auteur, aussi, présente les résultats intéressants de ces efforts. Rogers indique, aussi, des attitudes à être développées pour ceux qui s´ interessent à rendre facile l’apprentissage », et recommande des méthodes pour développer ces attitudes. À la fin, il suggère un plan pratique pour un changement révolutionnaire dans le système d’enseignement.The book "Freedom to Learn" by Carl R. Rogers left questions about the educational system. He wrote that educators in an attempt to motivate change and the desire to accomplish something concrete. For this purpose, available to all, he could see working in his own experience. Provides examples of how teachers, working at different levels of education, have found ways to provide freedom to learn, and has interesting consequences of these efforts. Also the book shows the attitudes to be developed by those interested in being a "learning facilitator", and recommends methods to develop these attitudes. Finally, it suggests a practical plan with a view to revolutionary changes in education.A obra "Liberdade para Aprender", de Carl R.

Oferece exemplos que mostram como professores, trabalhando em níveis diferentes de ensino, descobriram maneiras de proporcionar liberdade para aprender, e apresenta consequências interessantes destes esforços. Aponta, ainda, atitudes a serem desenvolvidas por quem se interessa em ser "facilitador de aprendizagem", e recomenda métodos para desenvolver estas atitudes. Por fim, sugere um plano prático com vistas a mudanças revolucionárias no sistema de ensino
