Using Airborne High Spectral Resolution Lidar Data to Evaluate Combined Active Plus Passive Retrievals of Aerosol Extinction Profiles

Aerosol extinction profiles are derived from backscatter data by constraining the retrieval with column aerosol optical thickness (AOT), for example from coincident MODIS observations and without reliance on a priori assumptions about aerosol type or optical properties. The backscatter data were acquired with the NASA Langley High Spectral Resolution Lidar (HSRL). The HSRL also simultaneously measures extinction independently, thereby providing an ideal data set for evaluating the constrained retrieval of extinction from backscatter. We will show constrained extinction retrievals using various sources of column AOT, and examine comparisons with the HSRL extinction measurements and with a similar retrieval using data from the CALIOP lidar on the CALIPSO satellite

Academic Listening Comprehension: Does the Sum of the Parts Make up the Whole?

A listening test administered to eighty-five non-native speaker students demonstrated that: (a) a significant relationship exists between global academic listening comprehension (ALC) and a subset of four microskills –inferring the meaning of unfamiliar vocabulary, and recognizing the respective functions of referential devices, conjunctive devices, and transitional devices; (b) each microskill tested is related to global ALC at p < .001 (correlattions ranged between .377 and .477); (c) common factors are involved in the skills of recognizing the functions of markers of cohesion and markers of coherence; (d) the relationship between global ALC and the ability to identify the main idea in short listening passages is significant but not particularly strong (r = .462). These findings imply that it might be useful to include microskill exercises in materials used for teaching and testing ALC

Oca, origens, cultura e ambiente

Apresentamos um conjunto de ações, iniciadas em 2014 e hoje em andamento, no município de Gurupá, Pará. É um trabalho realizado pelo Projeto OCA – Origens, Cultura e Ambiente, do Museu Paraense Emílio Goeldi. Este texto discute formas de engajamento entre arqueólogos e a comunidade em torno de reflexões sobre a história, memória e do patrimônio cultural. Argumenta pela construção coletiva do conhecimento arqueológico

Data Warehousing and the Organization of Governmental Databases

Data warehousing is a technology architecture designed to organize disparate data sources into a single repository of information. As such, it represents a strategy for creating the architecture necessary to support the vision of e-government. Data warehousing enables a new type of “decision intelligence” by providing access to historical trend data, typically difficult to retrieve through operational database systems. Government data warehousing is complex, expensive, and often fraught with data privacy and security issues. E-government goals may be met through a successful data-warehousing project, be it in the form of a more efficient, informed government or as a result of increased public access to information. But given the substantial barriers to success, a thorough planning and investigation process is necessary. </jats:p
