    A Geographical Location Model for Targeted Implementation of Lure-and-Kill Strategies Against Disease-Transmitting Mosquitoes in Rural Areas

    Outdoor devices for luring and killing disease-transmitting mosquitoes have been proposed as potential com- plementary interventions alongside existing intra-domiciliary methods namely insecticide treated nets and house spraying with residual insecticides. To enhance effectiveness of such outdoor interventions, it is essential to optimally locate them in such a way that they target most of the outdoor mosquitoes. Using odour-baited lure and kill stations (OBS) as an example, we describe a map model derived from: 1) com-munity participatory mapping conducted to identify mosquito breeding habitats, 2) entomological field studies conducted to estimate outdoor mosquito densities and to determine safe distances of the OBS from human dwellings, and 3) field surveys conducted to map households, roads, outdoor human aggregations and landmarks. The resulting data were combined in a Ge- ographical Information Systems (GIS) environment and analysed to determine optimal locations for the OBS. Separately, a GIS-interpolated map produced by asking community members to rank different zones of the study area and show where they expected to find most mosquitoes, was visually compared to another map interpolated from the entomological survey of outdoor mosquito densities. An easy-to-interpret suitability map showing optimal sites for placing OBS was produced, which clearly depicted areas least suitable and areas most suitable for locating the devices. Comparative visual interpretation of maps derived from interpolating the community knowledge and entomological data revealed major similarities between the two maps. Using distribution patterns of human and mosquito populations as well as characteristics of candidate outdoor interventions, it is possible to readily determine suitable areas for targeted positioning of the interventions, thus improve effectiveness. This study also highlights possibilities of relying on community knowledge to approximate areas where mosquitoes are most abundant and where to locate outdoor complementary interventions such as odour-baited lure and kill stations for controlling disease-transmitting mosquitoes.\u

    A strategy for achieving manufacturing statistical process control within a highly complex aerospace environment

    This paper presents a strategy to achieve process control and overcome the previously mentioned industry constraints by changing the company focus to the process as opposed to the product. The strategy strives to achieve process control by identifying and controlling the process parameters that influence process capability followed by the implementation of a process control framework that marries statistical methods with lean business process and change management principles. The reliability of the proposed strategy is appraised using case study methodology in a state of the art manufacturing facility on Multi-axis CNC machine tools

    Black Labor at Pine Grove & Caledonia Furnaces, 1789-1860

    Full text link
    Black labor operating under various degrees of freedom found a suitable working environment, if not a safe haven, in several iron forges of South Central Pennsylvania, from the late 1790s through the 1850s. Primary accounts indicate that two in particular, Pine Grove Furnace of Cumberland County, and Caledonia Furnace of Franklin County, harbored runaway slaves to augment their work force. Pine Grove records, dating from 1789 – 1801, specify names of “negro” employees, verifying that black labor coexisted with white, but day books, journals, and ledgers do not denote status.1 Whether they were free men, or slaves rented out by Pennsylvania slave owners, or runaways from the South cannot be gleaned from the day books. All three combinations were possible, especially in the 1790s. Circumstantial evidence suggests that escaped slaves did bolster the ranks of both forges until 1860. With renowned abolitionist Thaddeus Stevens in ownership of Caledonia, and proprietors sympathetic to the same cause at Pine Grove, the environment favored Underground Railroad activity. When this circumstance is coupled with the presence of a Quaker Meeting House in northern Adams County, and the recognition that both forges were within a thirty mile radius of the Maryland slave-state border, then a recipe existed for hide-outs to be employed in area furnaces.

    Where Spirit and Bulldozer Roam: Environment and Anxiety in Highland Borneo

    Full text link
    This paper explores changing perceptions of the natural environment among the Kelabit, an indigenous people of the Borneo interior. It considers both traditional and post-Christian conversion understandings about forest spaces. The former animistic ritual practices of the Kelabit centered on a spiritual dialogue with the natural world and this dialogue was often marked by active efforts to avoid or mitigate danger through ritual practice. One key example presented here is the former ceremony of \u27calling the eagle\u27 (nawar keniu), a ritual employed in times of crisis that exemplifies the dialogical and entwined relationship Kelabit had to the natural world. Such former animistic beliefs are contrasted with contemporary Christian practices, including a local mountain retreat on Mount Murud and present-day political and economic anxieties over logging in the Kelabit Highlands, as a means to consider relationships between religion and attitudes toward the environment among the Kelabit

    Risk Assessment for Collaborative Operation: A Case Study on Hand-Guided Industrial Robots

    Get PDF
    Risk assessment is a systematic and iterative process, which involves risk analysis, where probable hazards are identified, and then corresponding risks are evaluated along with solutions to mitigate the effect of these risks. In this article, the outcome of a risk assessment process will be detailed, where a large industrial robot is used as an intelligent and flexible lifting tool that can aid operators in assembly tasks. The realization of a collaborative assembly station has several benefits, such as increased productivity and improved ergonomic work environment. The article will detail the design of the layout of a collaborative assembly workstation, which takes into account the safety and productivity concerns of automotive assembly plants. The hazards associated with hand-guided collaborative operations will also be presented

    Museums for all: translation and interpreting for multimodal spaces as a tool for universal accessibility

    Get PDF
    Audiovisual Translation (AVT) has a scientific responsibility to develop analytical methodologies for the textual phenomenon of multimodality, and for the translation strategies associated with it. At the same time, it should aim to provide studies of universal accessibility with a powerful tool for facilitating access to knowledge. This article offers some reflections on the theoretical foundations of AVT and considers how these are projected in the creation of new professional profiles, with specific application to universal accessibility in the museums.La Traducción Audiovisual (TAV) tiene la responsabilidad científica de desarrollar metodologías de análisis para el fenómeno textual de la multimodalidad así como para sus estrategias de traducción, a la vez que ha de proporcionar a los estudios en accesibilidad universal una poderosa herramienta de acceso al conocimiento. Este artículo ofrece reflexiones en torno a los fundamentos teóricos de la TAV y a la proyección de estos en nuevos perfiles profesionales; todo ello aplicado a la accesibilidad museística universal.This article is the English version of “Museos para todos.
