Hate speech and the normative foundations of regulation
OA Monitor ExerciseOA Monitor ExerciseOA Monitor ExerciseRacist incidents on American university campuses in the 1980s triggered a storm of publications by scholars who coined the phrase âhate speechâ for the legal lexicon. Some of the offences had already been subject to legal or institutional penalties for harassment or vandalism. Several universities nevertheless adopted broad codes of conduct to penalise hateful expression. For two decades, however, the US Supreme Court had been marching in the opposite direction. It was interpreting the Constitution's First Amendment to prevent federal or state government from punishing speakers solely on grounds of the viewpoints they expres
Taro Corm Quality and Postharvest Handling for Processing
Objectives to study the relationships between physiological age of corms, storage capabilities, and final snack food chip quality of dryland taro are outlined. Background information is to be developed that will assist in the development of the snack food chip market. The first problem is to define quality and attempt to focus on those aspects which are most important for fried chip manufacture
SAP TESTING OF NITRATE NITROGEN IN TOMATO
The usefulness of conventional tissue testing techniques is limited for monitoring and adjusting the nitrogen (N) status of rapidly growing crops, such as many vegetables, because of the frequent unavailability of sufficiently quick and reliable test results. The nitrate N status of Lycopersicon esculentum 'Celebrity' was monitored in a greenhouse study using "Merkoquant" quick-test nitrate strips to determine the effects of plant-to-plant variation and variation in leaf position and time of day on the levels of nitrate N detectable in petiole sap. Nitrate N levels decreased from 2800 ppm in 28-day-old plants to below 400 ppm in plants older than 68 days. Sap nitrate N concentrations were equal in the top, middle, and bottom of the canopy of 28-day-old plants, but decreased more rapidly in the top of the canopy as the plants developed. Tissue analysis results and sap test results concurred in showing that N availability had been growth limiting. No differences in sap nitrate concentrations were detected between 10 a.m., 12 p.m., and 2 p.m. ----- La utilidad de tecnicas convencionales para analizar tejidos de plantas para vigilar y ajustir el nivel de nitrogeno en cultivos de creciminento rapido, tales como muchas hortalizas, es limitada debido a la frequente indisponibilidad de resultados suficientes rapidos y seguros, EI nivel de nitr6geno en forma de nitrato de Lycopersicon esculentum 'Celebrity' fue vigilado en un estudio de invernadero usando laminas de nitrato de ensayo rapido "Merkoquant" para determinar los efectos de variaci6n entre plantas y la variaci6n en posicion de hoj y tiempo del dfa sobre los niveles de nitrato encontrados en la savia del peciolo. Los niveles de nitrato bajaron de 2800 ppm en plantas de 28 dras de edad a menos de 400 ppm en plantas mayores de 68 d(as de edad. Las concentraciones de nitrate en la savia eran iguales en la parte superior, la parte intermediana y la parte mas baja de plantas de 28 dias de edad, peru deerecieron mas rapido en la parte superior de las plantas mientras estas se desarrollaron. Resultados del analisis de tejidos y de la savia concurrieron que la disponibilidad de nitr6geno limitaba el crecimiento. No se noto ninguna diferencia en la concentraci6n de nitrato en la savia entre 10 a.m., 12 p.m. y 2 p.m
