ABSTRACT The intensive use of pesticides to control pests in agriculture has exposed the environment and humans to a variety of risks. Among the crops with higher consumption of these compounds there is the sugarcane, developed in regions bordered by large watersheds. In this work, the occurrence of pesticides in the water of Ipojuca River was investigated in a 50 km range of its eastern portion, in a region noted for intense agroindustrial activity, especially by sugarcane cultivation, in the state of Pernambuco. Among fungicides, herbicides, insecticides and carbamates, 238 pesticides were investigated in the Ipojuca River using the technique of liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). The study, conducted in the months of May, June, October and November 2012, detected the presence of Diuron and Ametryn herbicide residues in 100% of the water samples at concentrations from 0.01 to 1.4 μg L-1. The detection of these herbicides, even at residual concentrations, can lead to perceptible ecological changes in the long term, such as the reduction of the biological potential of animal and plant species.

The Morrison Formation has been explored for dinosaurs for more than 150 years, in particular for large sauropod skeletons to be mounted in museum exhibits around the world. Several long-term campaigns to the Jurassic West of the United States produced hundreds of specimens, ranging from isolated, fragmentary bones to nearly complete skeletons of these enormous herbivorous animals. Given the sheer number of specimens, keeping track of what is housed in which institution is paramount to study variability, taxonomy, and consequently geographic and temporal distribution of the various species and genera recognized from the Morrison Formation. In an attempt to facilitate these studies, we have compiled an online spreadsheet intended to combine all the available information on sauropod specimens from collection databases, published literature, and personal observations. These include lists of contents of the specimens, in what institution the material is housed, references mentioning, describing, figuring, providing measurements and/or 3D scans, locality data and stratigraphy, as well as other potentially useful data for research purposes. The spreadsheet is openly accessible, but editing is currently restricted to the authors of this study, in order to ensure high-quality data curation to keep the file as useful as possible.

Land surface temperature (LST) is a key parameter of land surface physical processes on global and regional scales, linking the heat fluxes and interactions between the ground and atmosphere. Based on MODIS 8-day LST products (MOD11A2) from the split-window algorithms, we constructed and obtained the monthly and annual LST dataset of Fujian Province from 2000 to 2015. Then, we analyzed the monthly and yearly time series LST data and further investigated the LST distribution and its evolution features. The average LST of Fujian Province reached the highest in July, while the lowest in January. The monthly and annual LST time series present a significantly periodic features (annual and interannual) from 2000 to 2015. The spatial distribution showed that the LST in North and West was lower than South and East in Fujian Province. With the rapid development and urbanization of the coastal area in Fujian Province, the LST in coastal urban region was significantly higher than that in mountainous rural region. The LST distributions might affected by the climate, topography and land cover types. The spatio-temporal distribution characteristics of LST could provide good references for the agricultural layout and environment monitoring in Fujian Province.

Anthropogenic Aerosol

Abstract Recent studies have revealed significant impacts of increased concentration of anthropogenic aerosols in the atmosphere to both climate and human health. Southeast Africa is one of the regions where studies related to atmospheric aerosols remain scant, causing high uncertainty in predicting and understanding the impacts of these aerosols to both climate and human health. The present study therefore has investigated the long term spatial-temporal distribution of atmospheric aerosols, trends, its relationship with cloud properties and the associated atmospheric circulation over the region. High concentration of aerosol has been detected during the dry months of September to November (SON) while low during March to May (MAM) and June-July (JJA) seasons in most areas. Highest 550 was recorded in areas with low elevation such as over Lake Malawi, Zambezi valley and along the western coast of the Indian Ocean. The average of the detected concentration is however low as compared to highly polluted regions of the globe. Statistical analyses revealed insignificant change of AOD550 in most areas between 2002 and 2020 time period. The study has also revealed seasonality of aerosol distribution highly influenced by changes in atmospheric circulation. Burning of biomass during dry months such bush fires and burning of crop residues remain the major source of anthropogenic aerosol concentration over Southeast Africa hence needs to be controlled.

The Relationship

Climatic change is expected to affect forest development in the short term, as well as the spatial distribution of species in the long term. Species distribution models are potentially useful tools for guiding species choices in reforestation and forest management prescriptions to address climate change. The aim of this study is to build spatial and spatio-temporal models to predict the distribution of four different species present in the Spanish Forest Inventory. We have compared the different models and showed how accounting for dependencies in space and time affect the relationship between species and environmental variables.

Over more than four decades odour research in the aquatic sciences has increasingly focused on cyanobacteria and the common odour-causing compounds, geosmin and 2-methylisoborneol. Success in future research requires a long-term perspective. Key areas for investigation are secondary metabolites and cyanobacteria, regulatory mechanisms for geosmin and other compounds' synthesis; understanding their spatial and temporal distribution (particularly relating to the food web in a habitat); and molecular mechanisms for liberation of geosmin by microorganisms.

Hospital Operations

Staff scheduling has historically been embedded within hospital operations, often defined by each new manager of a unit or program, and notably absent from the organization's practice and standards infrastructure and accountabilities of the executive team. Silvestro and Silvestro contend that “there is a need to recognize that hospital performance relies critically on the competence and effectiveness of roster planning activities, and that these activities are therefore of strategic importance.”1 This article highlights the importance of including staff scheduling — or workforce deployment — in health care organizations' long-term strategic solutions to cope with the deepening workforce shortage (which is likely to hit harder than ever as the economy begins to recover). Viewing workforce deployment as a key organizational competency is a critical success factor for health care in the next decade, and the Workforce Deployment Maturity Model© is discussed as a framework to enable organizations to measure their current capabilities, identify priorities and set goals for increasing organizational competency using a methodical and deliberate approach.
