Farm Sustainability

AbstractIn the paper, an approach to measure farm level sustainability with the Synthetic Farm Sustainability Index (SFSI) is presented. SFSI is composed of five partial sustainability indexes based on 56 parameters describing different aspects of farms organization and functioning. The index, calculated for the sample of 120 Polish farms, was used to measure the state (static sustainability) and effects of possible improvements (dynamic sustainability) in the farming system. The results of the analyses show significant differences in the sustainability level between the farms in the sample, as well as the potential for increasing SFS. The increase of the synthetic sustainability index can be achieved by means of farm investments, but also low-cost activities that improve environmental performance and generate positive social effects without undermining economic viability. It was also found out, that larger size, intensive farms can achieve high economic and environmental sustainability level if properly managed.

On Farm

Abstract In the context of an expanding, export-dependent agri-food sector, indicators of sustainable development and intensification are necessary to measure, assess and verify the comparative advantage afforded by Ireland’s natural pastoral-based food production systems. Such indicators are also necessary to ensure that we produce more food with less adverse impacts on the Irish environment, climate and society. This article outlines the development of farm-level indicators that refect the multifaceted nature of sustainability, which is encompassed in economic, environmental and social indicators. The role of innovation in farm sustainability was also examined. A comparison of indicators across Irish farm systems showed that dairy farms, followed by tillage farms, tended to be the most economically and socially sustainable farm systems. In relation to greenhouse gas emissions in particular, the top-performing dairy farms, in an economic sense, also tended to be the best-performing farms from an environmental sustainability perspective. This trend was also evident in relation to the adoption of innovative practices on farm, which was found to be strongly correlated with economic performance.

Hospital Conversions

The pressures encountered by hospitals in the current era of reimbursement declines and stiffened competition are well known. As the “ultimate” payors—primarily employers and government—aggressively continue to seek low cost care, the response of the hospital industry has been to move toward consolidation and efficiency-enhancing mechanisms.Increasingly, nonprofit, tax-exempt hospitals have come to believe that they are at a significant disadvantage vis-á-vis their for-profit brethren in their ability to attract the capital needed to compete in the market. A growing trend among nonprofit hospitals, therefore, is to sell to or enter into a joint venture with a proprietary organization, or alternatively to convert to for-profit status. In 1995, fifty-eight nonprofit hospitals became for-profit; hospital conversions to for-profit status in 1996 are projected to outstrip the pace established the prior year.The conversion trend has not gone unnoticed at the state level. Recently, several states have proposed or enacted laws regulating sales and conversions of nonprofit hospitals, and many more states are contemplating such legislation.

Wood Mulch

In this study, wood mulch-based amendments were tested in a bench-scale microcosm experiment in order to assess the treatability of saturated soils and groundwater from an industrial site contaminated by chlorinated ethenes. Wood mulch was tested alone as the only electron donor in order to assess its potential for stimulating the biological reductive dechlorination. It was also tested in combination with millimetric iron filings in order to assess the ability of the additive to accelerate/improve the bioremediation process. The efficacy of the selected amendments was compared with that of unamended control microcosms. The results demonstrated that wood mulch is an effective natural and low-cost electron donor to stimulate the complete reductive dechlorination of chlorinated solvents to ethene. Being a side-product of the wood industry, mulch can be used in environmental remediation, an approach which perfectly fits the principles of circular economy and addresses the compelling needs of a sustainable and low environmental impact remediation. The efficacy of mulch was further improved by the co-presence of iron filings, which accelerated the conversion of vinyl chloride into the ethene by increasing the H2 availability rather than by catalyzing the direct abiotic dechlorination of contaminants. Chemical analyses were corroborated by biomolecular assays, which confirmed the stimulatory effect of the selected amendments on the abundance of Dehalococcoides mccartyi and related reductive dehalogenase genes. Overall, this paper further highlights the application potential and environmental sustainability of wood mulch-based amendments as low-cost electron donors for the biological treatment of chlorinated ethenes.

Important Cash Crop

Potatoes are an important cash crop for small-scale producers worldwide. The move away from subsistence to commercialized farming, combined with the rapid growth in demand for processed agricultural products in developing countries, implies that small-scale farmers and researchers alike must begin to respond to these market changes and consider post-harvest treatment as a critical aspect of the potato farming system. This paper presents and assesses a low cost potato-grading machine that was designed explicitly to enable small-scale potato growers to sort tubers by size for supply to commercial processors. The results of ten experiments reveal that the machine achieves an accuracy of sort similar to commercially available graders. The machine, which uses parallel conical rollers, has the capacity to grade different tuber shapes and to adjust sorting classes, making it suitable for locations with high potato diversity. Its relatively low cost suggests that an improved and adapted version of this machine might enhance market integration of small-scale potato producers not only in Peru, but in other developing countries as well.

Background and Purpose: Kansas is a rural state lacking geographically distributed Primary Stroke Centers. Of the 128 hospitals in the state, 88 are designated as Critical Access (< 25 beds). The IV r-tPA treatment rate in the state of Kansas is less than 2%. The pre-transport death rate for patients experiencing stroke is 55.4% .The Kansas Initiative for Stroke Survival (KISS) is a non-government task force with the goal of improving stroke survival among Kansans. The task force encourages hospitals to meet the criteria as Emergent Stroke Ready and based on this status engage with their individual communities, emphasizing the need to seek immediate assistance by EMS and arrive at the closest Emergent Stroke Ready hospital. Methods: The Kansas State Stroke Task force determined requirements for a facility to be considered Emergent Stroke Ready. This information was distributed to all acute care hospitals, asking them to attest to their current Emergent Stroke Ready status. Responding facilities were provided access to a 24 x 7 Stroke Support Line - providing access to stroke specialists for the purpose of guiding evaluation and treatment decisions for r-tPA administration or need to transfer to a higher level of care. Also provided is a community education kit. Data is reported through a monthly online survey or GWTG database. Results: In the first phase of the KISS project - forty-two hospitals attested as Emergent Stroke Ready Hospital or were certified Primary Stroke Centers representing an increase from 7% to 33% of hospitals in the state. The post-KISS implementation IV r-tPA treatment rate for the reporting Emergent Stroke Ready Hospitals was 48% compared with a pre-KISS treatment rate of 6%. The post-KISS implementation transfer rate was 26.7% compared with a pre-KISS transfer rate of 18%. Conclusions: The KISS program resulted in a significant increase in the number of Emergent Stroke Ready facilities, stroke patients reporting to their local hospitals, stroke specialist consultations and use of IV r-tPA. A low-cost, statewide program that provides standardized protocols and direct phone consultation can improve access to stroke specialists and approved stroke treatment while offering a cost effective, feasible alternative to telestroke.
