Busybody, Hunter, Dancer: Three Historical Models of Curiosity

A paper discussing neuroscience, education, politics, racism, decolonialism.

A standard and comprehensive model is needed to evaluate and compare technology transfer systems and the stakeholders within these systems. The principle systems considered include federal laboratories, U.S. universities, the rehabilitation engineering research centers (RERCs), and large small business innovation research programs. An earlier model accounts for technology transfer activities, events, stakeholders, and resource providers . This model is augmented to account for dynamic aspects of technology transfer (transfer efficiency, transfer latency) and scale (micro-, macro-). The critical role of technology transfer intermediaries is emphasized. Examples pertaining to the assistive technology industry are used to illustrate important concepts and issues. The technology transfer model with extensions is applied to the four technology transfer systems. Major studies pertaining to the technology transfer performance of: large small business innovation research programs, the federal laboratory system, the U.S. Department of Education RERCs, and U.S. universities are reviewed. Study outcomes are examined in terms of a uniform and comprehensive technology transfer model. Conclusions are drawn regarding the evaluation of program performance. The need for a uniform and comprehensive technology transfer model is demonstrated by showing inconsistencies within and between research study outcomes for major technology transfer systems. Barriers that prevent the full and optimal use of these programs by the assistive technology industry are discussed. The

Given the dismal state of world fisheries and their continuing decline—exacerbated by climate change—aquaculture is touted by some to be a promising means for fulfilling the growing global demand for seafood, as reflected in its rapid growth as a segment of the global food system. However, large-scale aquaculture presents a complex set of environmental and social issues, and the introduction of genetically engineered fish and seafood add a further layer of complexity to the already contentious nature of conventional aquaculture practices. This article is a critical analysis of aquaculture regulation in Canada. In addition to setting out some of the major issues posed by industrialized aquaculture, it argues that shifting the " production " of seafood from marine fisheries to aquaculture merely shifts the cause of environmental damages. Further, in the context of food security, large-scale aquaculture is an inadequate and oversimplified solution to the problems raised by coastal and Indigenous populations' reliance on declining fisheries resources. Specifically, using two case studies, this paper criticizes the overreliance within the current system on dominant risk paradigms, which are often closely informed by science. Yet, the relationship between law and science is fraught with tensions, as the two have notably different priorities and methods. In rethinking the role of aquaculture in natural marine resource management, especially in a changing climate, it is important to ensure that careful regard is given to the socio-cultural factors, inequities, and environmental degradation that are inherent in the production of seafood.

El presente texto pretende trabajar a partir de la inquietud que nos plantea una pregunta: ¿Cómo recuperar una tematización de la relación educativa que sostenga un proyecto educativo basado en nociones de justicia e igualdad? El interrogante surge a partir de las tensiones actualmente en curso en los esfuerzos que desde gobiernos denominados genéricamente como progresistas se vienen produciendo en el intento de avanzar en la democratización de la educación. Si bien la mirada busca ampliarse en términos latinoamericanos, su foco está puesto explícitamente en el caso uruguayo. El recorrido que se propone se organiza en cuatro momentos. Se inicia con una breve contextualización histórica, avanza en la identificación de tensiones propias de la coyuntura actual, propone algunas claves conceptuales para abordar un trabajo con la pregunta planteada y cierra con algunas reflexiones que cumplen la función de habilitar la continuidad de un pensamiento.

Hydrogen sulfide is a colorless, corrosive, toxic and flammable gas that is notorious for its nuisance rotten egg odor. Hydrogen sulfide endangers environment, human health and industrial equipment. Despite its high heating value, utilization of hydrogen sulfide as fuel is strictly prohibited using conventional combustion technologies. This malignant gas naturally exists in crude oil and natural gas wells. The separated-out hydrogen sulfide from crude oil and gas has other impurities that include: carbon dioxide, nitrogen, ammonia, carbonyl sulfide, carbon disulfide as well as benzene, toluene and xylene (commonly referred to as BTX). With the increase in energy demand, there will be reliance on utilization of sourer feedstock. Consequently, hydrogen sulfide stream needs to be efficiently treated. On the other hand, hydrogen sulfide is considered a hydrogen rich feedstock. In addition, the hydrogen-constituted impurities, such as: methane, ammonia and BTX in the separated-out hydrogen sulfide stream from crude oil and gas furtherly enrich the hydrogen feedstock of this stream. Hydrogen can be produced from the decomposition of hydrogen sulfide into its two valuable constituents: hydrogen and sulfur. Thermal decomposition of hydrogen sulfide was studied in this work. Experimental examination of wide range of several key parameters that affect the amounts of hydrogen produced and destructed hydrogen sulfide was conducted. Effect of inlet acid gas composition as well as role of different contaminant gases naturally accompanying H2S on the chemistry, production of hydrogen and destruction of hydrogen sulfide were studied. A chemical reaction mechanism that characterizes hydrogen sulfide thermal decomposition as well as decomposition of a mixture of hydrogen sulfide with methane over wide range of conditions was developed. The developed mechanism addresses the chemical kinetics and possible pathways. The difference in dominant reaction pathways between the two cases of presence and absence of impurities facilitated the identification of the role played by the contaminants.

Climate change and its associated extreme climate and extreme events are threat to man and his environment. Over the years, climatic parameters have been used as climate change indicators to study climate change. In order to access extreme climate due to climate change in Nigeria, this paper attempt to evaluate spatial distribution and temporal trends of temperature and its extremes over Nigeria for 35 years (1979 - 2013). Daily temperature data used were obtained from the Nigeria Meteorological Agency (NIMET), Lagos. The data was subjected to quality checked and homogenization. Climate extreme indices developed by the Expert Team on Climate Change Detection and Indices (ETCCDI) was adopted in this study. The data were analysed employing Sen’s slope estimator and Mann-Kendall test. Results revealed that spatial distribution of temperature and its extremes over Nigeria varied across the country, increasing/decreasing mostly towards the northern or the coastal regions. Significant inc...
