    Despite the 1989 ivory trade ban, elephants continue to be killed to harvest their tusks for ivory. Since 2008, this poaching has increased to unprecedented levels driven by consumer demand for ivory products. CITES is now considering the development of a legal ivory trade [1, 2]. The proposal relies on three assumptions: (1) harvest regulation will cease all illegal activities, (2) defined sustainable quotas can be enforced, and (3) we can define meaningful sustainable quotas that come close to the current demand. We know that regulation of harvest does not stop illegal takes. Despite whaling regulation after World War II, illegal whaling continued for decades [3]. The introduction of wolf culls in the US actually increased poaching activities [4], and one-off ivory sales in 1999 and 2008 did nothing to halt elephant poaching. Governance issues over the ivory supply chains, including stockpiling, make enforcing quotas challenging, if not impossible [5, 6]. We have not yet adequately assessed what could be a sustainable ivory yield. To do so, we develop a compartmental model composed of a two-sex age-structured demographic model and an ivory production and harvest model. We applied several offtake and quota strategies to define how much ivory could be sustainably harvested. We found that the sustainability space is very small. Only 100 to 150 kg of ivory could be removed from a reference population of 1,360 elephants, levels well below the current demand. Our study shows that lifting the ivory ban will not address the current poaching challenge. We should instead focus on reducing consumer demand. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Kanstrup, Niels

    of modern mankind. In many remote regions, waterbirds are still an important food resource. At the same time, sustainable utilization at all levels is regarded as a cornerstone in the conservation of nature. Sustainability is considered from the perspectives of two main fields: ecology and socio......-economic (political) issues. Aspects of ecological sustainability include the harvest and other direct impacts on bird populations, here regarded as the hunting pressure. Socio-economic aspects include the active participation in nature conservation by local communities, motivated by the access to natural resources...... and the degree of stability in local communities obtained through nature conservation. In many countries there is a long tradition of detailed wildlife harvest management including programmes for bag surveys and monitoring of harvest levels. In most countries, however, the management of waterbird harvests...

    2007-04-01

    The DOE Biomass Program recently implemented the Biofuels Initiative, or 30x30 program, with the dual goal of reducing U.S. dependence on foreign oil by making cellulosic ethanol cost competitive with gasoline by 2012 and by replacing 30 percent of gasoline consumption with biofuels by 2030. Experience to date with increasing ethanol production suggests that it distorts agricultural markets and therefore raises concerns about the sustainability of the DOE 30 X 30 effort: Can the U.S. agricultural system produce sufficient feedstocks for biofuel production and meet the food price and availability expectations of American consumers without causing environmental degradation that would curtail the production of both food and fuel? Efforts are underway to develop computer-based modeling tools that address this concern and support the DOE 30 X 30 goals. Beyond technical agronomic and economic concerns, however, such models must account for the publics’ growing interest in sustainable agriculture and in the mitigation of predicted global climate change. This paper discusses ongoing work at the Center for Advanced Energy Studies that investigates the potential consequences and long-term sustainability of projected biomass harvests by identifying and incorporating “sustainable harvest indicators” in a computer modeling strategy.

    Sérgio Gustavo Quassi de Castro

    2014-02-01

    Full Text Available The presence of trash from the mechanical harvest of green cane on sugarcane plantations promotes changes in the agricultural management, for example, in the mechanical cultural practices of ratoon cane in-between the rows and nitrogen (N fertilization. The goal of this study was to evaluate the performance of sugarcane in different harvest systems, associated to the mechanical cultural practices in interrows and N rates. The study was carried out on a sugarcane plantation in Sales Oliveira, São Paulo, Brazil, with the sugarcane variety SP81-3250, on soil classified as Acrudox, in a randomized block design with split-split plots and four replications. The main treatments consisted of harvest systems (harvesting green cane or burnt cane, the secondary treatment consisted of the mechanical cultural practices in the interrows and the tertiary treatments were N rates (0, 30, 60, 90, 120 and 160 kg ha-1, using ammonium nitrate (33 % N as N source. The harvest systems did not differ in sugarcane yield (tons of cane per hectare - TCH, but in burnt cane, the pol percent and total sugar recovery (TSR were higher. This could be explained by the higher quantity of plant impurities in the harvested raw material in the system without burning, which reduces the processing quality. Mechanical cultural practices in the interrows after harvest had no effect on cane yield and sugar quality, indicating that this operation can be omitted in areas with mechanical harvesting. The application of N fertilizer at rates of 88 and 144 kg ha-1 N, respectively, increased stalk height and TCH quadratically to the highest values for these variables. For the sugar yield per hectare (in pol %, N fertilization induced a linear increase.

    2015-03-17

    The microbial fuel cell (MFC) technology offers sustainable solutions for distributed power systems and energy positive wastewater treatment, but the generation of practically usable power from MFCs remains a major challenge for system scale up and application. Commonly used external resistors will not harvest any usable energy, so energy-harvesting circuits are needed for real world applications. This review summarizes, explains, and discusses the different energy harvesting methods, components, and systems that can extract and condition the MFC energy for direct utilization. This study aims to assist environmental scientists and engineers to gain fundamental understandings of these electronic systems and algorithms, and it also offers research directions and insights on how to overcome the barriers, so the technology can be further advanced and applied in larger scale.

  19. Differentiation of Alternate Harvesting Practices Using Annual Time Series of Landsat Data

    Directory of Open Access Journals (Sweden)

    Lukas R. Jarron

    2016-12-01

    Full Text Available Sustainable forest management practices allow for a range of harvest prescriptions, including clearcut, clearcut with residual, and partial or selective cutting, which are largely distinguished by the amount of canopy cover removed. The different prescriptions are aimed to emulate natural disturbance, encourage regeneration (seed trees, or offer other ecosystem services, such as the maintenance of local biodiversity or habitat features. Using remotely sensed data, stand-replacing disturbance associated with clearcutting is commonly accurately detected. Novel time series-based change detection products offer an opportunity to determine the capacity to detect and label a wider range of harvest practices. In this research, we demonstrate the capacity of time series imagery, spectral metrics, and related attributed change products, to distinguish between different harvesting practices over a study area in central British Columbia, Canada. Producer’s accuracy of harvest attribution was 79%, with 93% of harvest blocks >5 ha accurately identified. In relation to the amount of canopy cover removed, clearcut harvesting was the most accurately classified (84%, followed by clearcut with residual (79%, and partial cut (64%. Applying detailed spectral metrics derived from Landsat data revealed clearcut and partial cuts to be spectrally distinct. The annual nature of the Landsat time series also offers spatial harvest information within typical, often decadal, forest inventory update cycles. The statistically significant (p < 0.05 relationship between harvest practices and Landsat spectral information indicates a capacity to add increased attribution richness to remote sensing depictions of forest harvest.

    2007-01-01

    . Adding 5% mortality to defoliated palms caused stronger change in lamda, mainly due to changes in a high-elasticity vital rate (survival). Therefore, harvest practices that involve stem killing are clearly unsustainable. Our results show that commercial leaf cutting in Geonoma deversa is potentially sustainable, and that this is likely the case for understory palms in general. Our approach to evaluating harvest sustainability can be applied to other NTFPs.

    Udani, Janav P.; Arrieta, Andres F.

    2017-11-01

    Nonlinear energy harvesters have the potential to efficiently convert energy over a wide frequency range; however, difficulties in attaining and sustaining high-energy oscillations restrict their applicability in practical scenarios. In this letter, we propose an actuation methodology to switch the state of bi-stable harvesters from the low-energy intra-well configuration to the coexisting high-energy inter-well configuration by controlled phase shift perturbations. The strategy is designed to introduce a change in the system state without creating distinct metastable attractors by exploiting the basins of attraction of the coexisting stable attractors. Experimental results indicate that the proposed switching strategy yields a significant improvement in energy transduction capabilities, is highly economical, enabling the rapid recovery of energy spent in the disturbance, and can be practically implemented with widely used low-strain piezoelectric transducers.

  3. Sustainability of Rainwater Harvesting System in terms of Water Quality

    2014-01-01

    Full Text Available Water is considered an everlasting free source that can be acquired naturally. Demand for processed supply water is growing higher due to an increasing population. Sustainable use of water could maintain a balance between its demand and supply. Rainwater harvesting (RWH is the most traditional and sustainable method, which could be easily used for potable and nonpotable purposes both in residential and commercial buildings. This could reduce the pressure on processed supply water which enhances the green living. This paper ensures the sustainability of this system through assessing several water-quality parameters of collected rainwater with respect to allowable limits. A number of parameters were included in the analysis: pH, fecal coliform, total coliform, total dissolved solids, turbidity, NH3–N, lead, BOD5, and so forth. The study reveals that the overall quality of water is quite satisfactory as per Bangladesh standards. RWH system offers sufficient amount of water and energy savings through lower consumption. Moreover, considering the cost for installation and maintenance expenses, the system is effective and economical.

    Full Text Available Rainwater harvesting (RWH is perhaps the most ancient practice to meet water supply needs. It has received renewed attention since the 1970s as a productive water source, water savings and conservation means, and sustainable development tool. In RWH, it is important to know how much water can be harvested at a given location from a given catchment size, whether the harvested water meets the intended water quality, whether the RWH system is economically viable and whether the state regulations favor the RWH. Furthermore, the selected RWH system should be suitable to local rainfall and field conditions, downstream impacts, and socio-economic and cultural characteristics. In this regard, this paper provides an overview of the special issue on “Rainwater Harvesting: Quantity, Quality, Economics and State Regulations”. The selected papers cover a wide range of issues that are relevant to RWH such as regionalization of design curves, use of spatial technology, urban agriculture, arid-region water supply, multi criteria analysis and application of artificial neural networks.

  10. Estimating Sustainable Live-Coral Harvest at Kamiali Wildlife Management Area, Papua New Guinea.

    Directory of Open Access Journals (Sweden)

    Ken Longenecker

    Full Text Available Live coral is harvested throughout the Indo-West Pacific to make lime, used in the consumption of the world's fourth-most consumed drug, betel nut. Coral harvesting is an environmental concern; however, because lime-making is one of the few sources of income in some areas of Papua New Guinea (PNG, the practice is unlikely to stop. To better manage coral harvest, we used standard fishery-yield methods to generate sustainable-harvest guidelines for corymbose Acropora species found on the reef flat and crest at Lababia, PNG. We constructed a yield curve (weight-specific net annual-dry-weight production by: 1 describing the allometric relationship between colony size and dry weight, and using that relationship to estimate the dry weight of Acropora colonies in situ; 2 estimating annual growth of Acropora colonies by estimating in situ, and describing the relationship between, colony dry weight at the beginning and end of one year; and 3 conducting belt-transect surveys to describe weight-frequencies and ultimately to predict annual weight change per square meter for each weight class. Reef habitat covers a total 2,467,550 m2 at Lababia and produces an estimated 248,397 kg/y (dry weight of corymbose Acropora, of which 203,897 kg is produced on the reef flat/crest. We conservatively estimate that 30,706.6 kg of whole, dry, corymbose, Acropora can be sustainably harvested from the reef flat/crest habitat each year provided each culled colony weighs at least 1805 g when dry (or is at least 46 cm along its major axis. Artisanal lime-makers convert 24.8% of whole-colony weight into marketable lime, thus we estimate 7615.2 g of lime can be sustainably produced annually from corymbose Acropora. This value incorporates several safety margins, and should lead to proper management of live coral harvest. Importantly, the guideline recognizes village rights to exploit its marine resources, is consistent with village needs for income, and balances an equally

  14. Jungle Giants: Assessing Sustainable Harvesting in a Difficult-to-Survey Species (Python reticulatus.

    Directory of Open Access Journals (Sweden)

    Daniel J D Natusch

    Full Text Available Sustainability of wildlife harvests is critical but difficult to assess. Evaluations of sustainability typically combine modelling with the measurement of underlying abundances. For many taxa harvested in developing countries, however, abundances are near-impossible to survey and a lack of detailed ecological information impedes the reliability of models. In such cases, repeated surveys of the attributes of harvested individuals may provide more robust information on sustainability. If the numbers, sizes and other demographic attributes of animals taken for the commercial trade do not change over biologically significant time intervals (decades, there is a prima facie case that the harvest is indeed sustainable. Here, we report the results of examinations of > 4,200 reticulated pythons (Python reticulatus taken for the commercial leather industry in northern and southern Sumatra, Indonesia. The numbers, mean body sizes, clutch sizes, sizes at maturity and proportion of giant specimens have not decreased between our first surveys (1995 and repeat surveys (2015. Thus, despite assumptions to the contrary, the harvest appears to be sustainable. We use our data to inform the design of future monitoring programs for this species. Our study underpins the need for robust science to inform wildlife trade policy and decision-making, and urges wildlife managers to assess sustainability of difficult-to-survey terrestrial wildlife by drawing inferences directly from the harvest itself.

    1992-08-01

    A simple model of economic and ecological interplay for a system of two interacting populations grown in a closed environment and harvested periodically for economic purposes was analyzed. The analysis was carried out by exploring the parameter space of the model, defined by a discrete map, a harvesting strategy, and an objective functional. Results showed nonmonotonicities of the outcome and sharp sensitivities that depend on the values of the parameters and that are caused by the discrete nature of the system. This approach may prove useful for solving problems that cannot be solved analytically and for providing some guidance in the management of complex systems.

    Directory of Open Access Journals (Sweden)

    Sarah Ward

    2016-11-01

    Full Text Available Visualising interactions across urban water systems to explore transition and change processes requires the development of methods and models at different scales. This paper contributes a model representing the network interactions of rainwater harvesting (RWH infrastructure innovators and other organisations in the UK RWH niche to identify how resilience and sustainability feature within niche governance in practice. The RWH network interaction model was constructed using a modified participatory social network analysis (SNA. The SNA was further analysed through the application of a two-part analytical framework based on niche management and the safe, resilient and sustainable (‘Safe and SuRe’ framework. Weak interactions between some RWH infrastructure innovators and other organisations highlighted reliance on a limited number of persuaders to influence the regime and landscape, which were underrepresented. Features from niche creation and management were exhibited by the RWH network interaction model, though some observed characteristics were not represented. Additional Safe and SuRe features were identified covering diverse innovation, responsivity, no protection, unconverged expectations, primary influencers, polycentric or adaptive governance and multiple learning-types. These features enable RWH infrastructure innovators and other organisations to reflect on improving resilience and sustainability, though further research in other sectors would be useful to verify and validate observation of the seven features.

    Many islands in Korea have problems related to water source security and supply. In particular, the water supply condition is worse in small islands which are remote from the mainland. A couple of alternatives are developed and suggested to supply water to islands including water hauling, groundwater extraction, and desalination. However, these alternatives require much energy, cost, and concern in installation and operation. Rainwater harvesting is a sustainable option that supplies water with low energy and cost. However, lack of practical or comprehensive studies on rainwater harvesting systems in these regions hinders the promotion of the system. Therefore, this research examines defects of current RWH systems on an existing island, Guja-do, and provides technical suggestions in quantitative and qualitative aspects. A simple system design modification and expansion of system capacity using empty space such as a wharf structure can satisfy both the qualitative and the quantitative water demand of the island. Since rainwater harvesting is estimated to be a feasible water supply option under the Korean climate, which is an unfavorable condition for rainwater harvesting, implies a high potential applicability of rainwater harvesting technology to other regions over the world suffering from water shortage.

    Most mechanobiological investigations focused on in situ mechanical regulation of cells on stiffness-controlled substrates with few downstream applications, as it is still challenging to harvest and expand mechanically primed cells by enzymatic digestion (e.g., trypsin) without interrupting cellular mechanical memory between passages. This study develops thermoresponsive hydrogels with controllable stiffness to generate mechanically primed cells with intact mechanical memory for augmented wound healing. No significant cellular property alteration of the fibroblasts primed on thermoresponsive hydrogels with varied stiffness has been observed through thermoresponsive harvesting. When reseeding the harvested cells for further evaluation, softer hydrogels are proven to better sustain the mechanical priming effects compared to rigid tissue culture plate, which indicates that both the stiffness-controlled substrate and thermoresponsive harvesting are required to sustain cellular mechanical memory between passages. Moreover, epigenetics analysis reveals that thermoresponsive harvesting could reduce the rearrangement and loss of chromatin proteins compared to that of trypsinization. In vivo wound healing using mechanically primed fibroblasts shows featured epithelium and sebaceous glands, which indicates augmented skin recovery compared with trypsinized fibroblasts. Thus, the thermoresponsive hydrogel-based cell harvesting system offers a powerful tool to investigate mechanobiology between cell passages and produces abundant cells with tailored mechanical priming properties for cell-based applications. © 2017 WILEY-VCH Verlag GmbH & Co.

  14. Ecological carbon sequestration via wood harvest and storage: Practical constraints and real-world possibilities

    Science.gov (United States)

    Zeng, N.; King, A. W.; Zaitchik, B. F.; Wullschleger, S. D.

    2014-12-01

    A carbon sequestration strategy was recently proposed in which a forest is sustainably managed, and a fraction of the wood is selectively harvested and stored to prevent decomposition under anaerobic, dry or cold conditions. Because a large flux of CO2 is constantly assimilated into the world's forests via photosynthesis, partially cutting off its return pathway to the atmosphere forms an effective carbon sink. The live trees serve as a 'carbon scrubber' or 'carbon remover' that provides continuous sequestration. The stored wood is a semi-permanent carbon sink, but also serves as a 'biomass/bioenergy reserve' that could be utilized in the future if deemed more beneficial, for instance, by contributing to supply infrastructure for biomass power generation. Based on global forest coarse wood production rate, land availability, conservation, other wood use, and other practical constraints, we estimate a carbon sequestration potential for wood harvest and storage (WHS) 1-3 GtC y-1. The implementation of such a scheme at our estimated lower value of 1 GtC y-1 would imply a doubling of the current world wood harvest rate. This can be achieved by harvesting wood at a modest harvesting intensity of 1.2 tC ha-1 y-1, over a forest area of 8 Mkm2 (800 Mha). To achieve the higher value of 3 GtC y-1, forests need to be managed this way on half of the world's forested land, or on a smaller area but with higher harvest intensity. However, any successful implementation strategy will need to balance the needs of the local community and environment. It nonethelss provides a novel new addition to a portfolio of existing forest management strategies. We propose 'carbon sequestration and biomass farms' with mixed land use for carbon, energy, agriculture, as well as conservation, provided that governance issues are properly dealt with. In another example, the forests damaged by insects, fire, storms such as in the America West could be thinned to reduce fire danger and harvested for

    We designed and fabricated a bimorph cantilever array for sustainable power with an integrated Cu proof mass to obtain additional power and current. We fabricated a cantilever system using single-crystal piezoelectric material and compared the calculations for single and arrayed cantilevers to those obtained experimentally. The vibration energy harvester had resonant frequencies of 60.4 and 63.2 Hz for short and open circuits, respectively. The damping ratio and quality factor of the cantilever device were 0.012 and 41.66, respectively. The resonant frequency at maximum average power was 60.8 Hz. The current and highest average power of the harvester array were found to be 0.728 mA and 1.61 mW, respectively. The sustainable maximum power was obtained after slightly shifting the short-circuit frequency. In order to improve the current and power using an array of cantilevers, we also performed energy conversion experiments.

    Identification of potential sites for rainwater harvesting (RWH) is an important step toward maximizing water availability and land productivity in arid semiarid regions. Characterised as a "water scarce" country, Egypt has limited fresh water supplies, and is expected to suffer from water stress by the year 2030. Therefore, it is important to develop any means available to supply water and maintain human habitability in a sustainable manner. Practiced or simply indispensable in many countries around the world, rainwater harvesting (RWH) promotes a sustainable and efficient manner of exploiting water resources. In the present study, suitable areas for sustainable stormwater harvesting and storage in Egypt were identified using remote sensing for land cover data - location assessment linked to a decision support system (DSS). The DSS took into consideration a combination of thematic layers such as rainfall surplus, slope, potential runoff coefficient (PRC), land cover/use, and soil texture. Taking into account five thematic layers, the spatial extents of RWH suitability areas were identified by an analytical hierarchy process (AHP). The model generated a RWH map with five categories of suitability: excellent, good, moderate, poor and unsuitable. The spatial distribution of these categories in the area investigated was such that 4.8% (47910 km(2)) and 14% (139739 km(2)) of the study area was classified as excellent or good in terms of RWH, respectively, while 30.1% (300439 km(2)), 47.6% (474116 km(2)) and 3.5% (34935 km(2)) of the area were classified as moderate, unsuitable and poor, respectively. Most of the areas with excellent to good suitability had slopes of between 2% and 8% and were intensively cultivated areas. The major soil type in the excellent suitability areas was loam, while rainfall ranged from 100 to 200 mm yr(-1). The use of a number of RWH sites in the excellent areas is recommended to ensure successful implementation of RWH systems.

  20. Evaluating Water Management Practice for Sustainable Mining

    2014-02-01

    Full Text Available To move towards sustainable development, the mining industry needs to identify better mine water management practices for reducing raw water use, increasing water use efficiency, and eliminating environmental impacts in a precondition of securing mining production. However, the selection of optimal mine water management practices is technically challenging due to the lack of scientific tools to comprehensively evaluate management options against a set of conflicting criteria. This work has provided a solution to aid the identification of more sustainable mine water management practices. The solution includes a conceptual framework for forming a decision hierarchy; an evaluation method for assessing mine water management practices; and a sensitivity analysis in view of different preferences of stakeholders or managers. The solution is applied to a case study of the evaluation of sustainable water management practices in 16 mines located in the Bowen Basin in Queensland, Australia. The evaluation results illustrate the usefulness of the proposed solution. A sensitivity analysis is performed according to preference weights of stakeholders or managers. Some measures are provided for assessing sensitivity of strategy ranking outcomes if the weight of an indicator changes. Finally, some advice is given to improve the mine water management in some mines.

    Full Text Available Background and Purpose: In the EU political agenda, the use of forest biomass for energy has grown rapidly and significantly, in order to mitigate carbon dioxide emissions and reduce the energy dependence on fossil fuels of European member countries. The target of the EU climate and energy package is to raise the share of renewable energy consumption produced from renewable resources to 20% in 2020 (Directive 2009/28/EC. With regards to biomass energy, the supply of forest wood biomass is expected to rise by 45% (reference period: 2006-2020, in response to increasing demand for renewable sources. The increase of forest biomass supply could have both positive and negative effects on several forest ecosystem services (ESs and local development. These effects should be assessed in a proper manner and taken into account when formulating management strategies. The aim of the paper is to assess the environmental, economic and social sustainability of forest biomass harvesting for energy, using the Figure of Merit (FoM approach. Materials and Methods: Sustainability was assessed through a set of four indicators: two focused on experts’ opinions regarding the effects of forest biomass harvesting and the other two focused on the cost-benefit analysis (potential energy obtained and costs for wood chips. The research was developed through four case studies located in the Alpine Region. A semi-structured questionnaire was administered face-to-face to 32 selected experts. The perceived effects of forest biomass harvesting for energy on ESs and local development were evaluated by experts using a 5-point Likert scale (from “quite negative effect” to “quite positive effect”. Results: All experts agree that forest biomass harvesting has a positive effect on forest products provision and local economic development (employment of local workforce, local entrepreneurship and market diversification, while the effects on other ESs are controversial (e

    The unsustainable harvest of wildlife is a major threat to global biodiversity and to the millions of people who depend on wildlife for food and income. Past research has called attention to the fact that commonly used methods to evaluate the sustainability of wildlife hunting perform poorly, yet these methods remain in popular use today. Here, we conduct a systematic review of empirical sustainability assessments to quantify the use of sustainability indicators in the scientific literature and highlight associations between analytical methods and their outcomes. We find that indicator type, continent of study, species body mass, taxonomic group and socio-economic status of study site are important predictors of the probability of reported sustainability. The most common measures of sustainability include population growth models, the Robinson & Redford (1991) model and population trends through time. Indicators relying on population-specific biological data are most often used in North America and Europe, while cruder estimates are more often used in Africa, Latin America and Oceania. Our results highlight both the uncertainty and lack of uniformity in sustainability science. Given our urgent need to conserve both wildlife and the food security of rural peoples around the world, improvements in sustainability indicators are of utmost importance. © 2012 Blackwell Publishing Ltd/CNRS.

    Full Text Available Waterfowl harvest management in North America, for all its success, historically has had several shortcomings, including a lack of well-defined objectives, a failure to account for uncertain management outcomes, and inefficient use of harvest regulations to understand the effects of management. To address these and other concerns, the U.S. Fish and Wildlife Service began implementation of adaptive harvest management in 1995. Harvest policies are now developed using a Markov decision process in which there is an explicit accounting for uncontrolled environmental variation, partial controllability of harvest, and structural uncertainty in waterfowl population dynamics. Current policies are passively adaptive, in the sense that any reduction in structural uncertainty is an unplanned by-product of the regulatory process. A generalization of the Markov decision process permits the calculation of optimal actively adaptive policies, but it is not yet clear how state-specific harvest actions differ between passive and active approaches. The Markov decision process also provides managers the ability to explore optimal levels of aggregation or "management scale" for regulating harvests in a system that exhibits high temporal, spatial, and organizational variability. Progress in institutionalizing adaptive harvest management has been remarkable, but some managers still perceive the process as a panacea, while failing to appreciate the challenges presented by this more explicit and methodical approach to harvest regulation. Technical hurdles include the need to develop better linkages between population processes and the dynamics of landscapes, and to model the dynamics of structural uncertainty in a more comprehensive fashion. From an institutional perspective, agreement on how to value and allocate harvests continues to be elusive, and there is some evidence that waterfowl managers have overestimated the importance of achievement-oriented factors in

  9. Corn Belt soil carbon and macronutrient budgets with projected sustainable stover harvest

    Tan, Zhengxi; Liu, Shu-Guang

    2015-01-01

    Corn (Zea mays L.) stover has been identified as a prime feedstock for biofuel production in the U.S. Corn Belt because of its perceived abundance and availability, but long-term stover harvest effects on regional nutrient budgets have not been evaluated. We defined the minimum stover requirement (MSR) to maintain current soil organic carbon levels and then estimated current and future soil carbon (C), nitrogen (N), phosphorus (P), and potassium (K) budgets for various stover harvest scenarios. Analyses for 2006 through 2010 across the entire Corn Belt indicated that currently, 28 Tg or 1.6 Mg ha−1 of stover could be sustainably harvested from 17.95 million hectares (Mha) with N, P, and K removal of 113, 26, and 47 kg ha−1, respectively, and C removal for that period was estimated to be 4.55 Mg C ha−1. Assuming continued yield increases and a planted area of 26.74 Mha in 2050, 77.4 Tg stover (or 2.4 Mg ha−1) could be sustainably harvested with N, P, and K removal of 177, 37, and 72 kg ha−1, respectively, along with C removal of ∼6.57 Mg C ha−1. Although there would be significant variation across the region, harvesting only the excess over the MSR under current fertilization rates would result in a small depletion of soil N (−5 ± 27 kg ha−1) and K (−20 ± 31 kg ha−1) and a moderate surplus of P (36 ± 18 kg ha−1). Our 2050 projections based on continuing to keep the MSR, but having higher yields indicate that soil N and K deficits would become larger, thus emphasize the importance of balancing soil nutrient supply with crop residue removal.

    Full Text Available This study investigated the sustainability of the rainwater harvesting system (RWHS by analyzing six urban city sites with different rainfall statistics in the United States. We developed a new RWHS performance model by modifying a spreadsheet-based storage, treatment, and overflow runoff model (SS STORM and verified its performance by comparing with another analytical RWHS model. The sustainability index (SI evaluation method was used for a reservoir system and applied to the RWHS, employing modified resilience and vulnerability evaluation methods due to the different characteristics of a reservoir and the RWHS. The performance of modified SS STORM is very similar to that of the analytical method, except in Los Angeles, which is characterized by long inter-event times and low rainfall event depths due to low annual rainfall. The sustainability indices were successfully evaluated depending on both RWHS size and water demand and vary over a wide range as annual rainfall increases. This study proposes a new RWHS performance model and sustainability index evaluation method. Further study should confirm the proposed approach in regions with widely different rainfall characteristics.

  11. Increased energy harvesting from backpack to serve as self-sustainable power source via a tube-like harvester

    In recent years, there has been increasing demand for portable power sources because of the rapid development of portable and wearable electronic devices. This paper describes the development of a backpack-based energy harvester to harness the biomechanical energy of the human body during walking. The energy harvester was embedded into a backpack and used a spring-mass-damping system to transfer the energetic motion of the human body into rotary generators to produce electricity. In the oscillation system, the weight of the harvester itself and the load contained in the backpack serve together as the seismic mass; when excited by human trunk motion, the seismic mass drives a gear train to accelerate the harvested energetic motion, which is then delivered to a generator. A prototype device was built to investigate its performance, which has a maximum diameter of 50 mm, a minimum diameter of 28 mm, a length of 250 mm, and a weight of 380 g. Experiments showed that the proposed backpack-based harvester, when operating with a 5 kg load, could produce approximately 7 W of electrical power at a walking velocity of 5.5 km/h. The normalized power density of the harvester is 0.145 kg/cm3, which is 7.6 times as much as that of Rome's backpack harvester [26]. Based on the results of metabolic cost experiments, the average conversion efficiency from human metabolic power to electrical power is approximately 36%.

    Gregg, Jay S.; Izaurralde, Roberto C.

    2010-08-26

    Agricultural residues are a potential feedstock for bioenergy production, if residue harvest can be done sustainably. The relationship between crop residue harvest, soil erosion, crop yield and carbon balance was modeled with the Erosion Productivity Impact Calculator/ Environment Policy Integrated Climate (EPIC) using a factorial design. Four crop rotations (winter wheat [Triticum aestivum (L.)] – sunflower [Helianthus annuus]; spring wheat [Triticum aestivum (L.)] – canola [Brassica napus]; corn [Zea mays L.] – soybean [Glycine max (L.) Merr.]; and cotton [Gossypium hirsutum] – peanut [Arachis hypogaea]) were simulated at four US locations each, under different topographies (0-10% slope), and management practices [crop residue removal rates (0-75%), conservation practices (no till, contour cropping, strip cropping, terracing)].

  16. Are the Economically Optimal Harvesting Strategies of Uneven-Aged Pinus nigra Stands Always Sustainable and Stabilizing?

    Directory of Open Access Journals (Sweden)

    Carmen Fullana-Belda

    2013-10-01

    Full Text Available Traditional uneven-aged forest management seeks a balance between equilibrium stand structure and economic profitability, which often leads to harvesting strategies concentrated in the larger diameter classes. The sustainability (i.e., population persistence over time and influence of such economically optimal strategies on the equilibrium position of a stand (given by the stable diameter distribution have not been sufficiently investigated in prior forest literature. This article therefore proposes a discrete optimal control model to analyze the sustainability and stability of the economically optimal harvesting strategies of uneven-aged Pinus nigra stands. For this model, we rely on an objective function that integrates financial data of harvesting operations with a projection matrix model that can describe the population dynamics. The model solution reveals the optimal management schedules for a wide variety of scenarios. To measure the distance between the stable diameter distribution and the economically optimal harvesting strategy distribution, the model uses Keyfitz’s delta, which returns high values for all the scenarios and, thus, suggests that those economically optimal harvesting strategies have an unstabilizing influence on the equilibrium positions. Moreover, the economically optimal harvesting strategies were unsustainable for all the scenarios.

Biodiversitas 13: 00-00. Conservation of tropical trees can be achieved if supported by the sustainable use of forest by community live nearby through harvesting of non timber woods, for instance rattan. Furthermore, rattan jernang individuals and trees have significant associations. Therefore, objective of this paper is to investigate the utilization of rattan jernang (Deamonorops draco Wild related to the forest tree biodiversity by Anak Dalam tribe in several villages in Jambi, Sumatra. The study has identified that populations of Deamonorops draco were varied among villages, ranged from 40 to 71 clumps in the forests and up to 500 clumps in plantations. Moreover, 73 individual trees consisted of 32 species were identified as rattan host and conserved by the community. Dialium platyespalyum. Quercus elmeri, and Adinandra dumosa were rattan host trees with the highest populations. Meanwhile, a biodiversity of non-host trees consisted of 30 individual trees from 16 species. Interviews revealed that traditional harvesters have acknowledged that trees have significant important ecological roles for the rattan livelihood and therefore it is very important to conserve the forests for the sustainability of harvest in the future. Furthermore, to secure the availability of rattan, the traditional harvesters had started rattan plantation.

    Full Text Available Despite the efforts for sustainability studies in building and infrastructure construction, the sustainability issues in industrial construction remain understudied. Further, few studies evaluate sustainability and benchmark sustainability issues in industrial construction from a management perspective. This study presents a phase-based benchmarking framework for evaluating sustainability practices use focusing on industrial facilities project. Based on the framework, this study quantifies and assesses sustainability practices use, and further sorts the results by project phase and major project characteristics, including project type, project nature, and project delivery method. The results show that sustainability practices were implemented higher in the construction and startup phases relative to other phases, with a very broad range. An assessment by project type and project nature showed significant differences in sustainability practices use, but no significant difference in practices use by project delivery method. This study contributes to providing a benchmarking method for sustainability practices in industrial facilities projects at the project phase level. This study also discusses and provides an application of phase-based benchmarking for sustainability in industrial construction.

    2014-01-01

    Bark and exudates are widely commercialized non-timber forest products. However, the ecological impacts of the harvesting of these products have seldom been studied. The aim of this study is to investigate the relationship of tree resilience to harvesting intensity in Himatanthus drasticus, a tree that is highly exploited in the Brazilian savanna (Cerrado) for its medicinal latex. Although the traded product is the latex, the traditional harvesting systems involve the removal of the bark of the trees to allow exploitation. A 3-year experiment was conducted in two different Cerrado ecosystems (open savanna and savanna woodland). Trees were debarked at four debarking intensities to simulate the effects of traditional management systems. Measurements of bark growth were taken every 6 months, and quantitative and qualitative indexes of bark regeneration were obtained. The mortality of the debarked trees was low and could not be related to the intensity of harvesting. No signs of attack by fungi or insects were recorded. Compared with other species exploited for bark, H. drasticus is very resilient to harvesting; however, bark regeneration is relatively slow. In both analyzed ecosystems, the regeneration indexes showed higher values in the controls than in the treatments, indicating that 3 years is not sufficient for total recovery of the rhytidome. Bark regeneration occurred primarily by sheet growth and was more rapid in open savanna than in savanna woodland. No differences in the rate of bark recovery were found among management treatments. Based on the results, sustainable harvesting guidelines are suggested for the species.

  15. Evaluation of Sustainable Practices within Project Management Methods

    Shah Satya

    2017-01-01

    Full Text Available The purpose of this research study is to investigate some of the sustainable practices within projects with a focus on social projects. The different research methodologies applied through this research consisted both primary and secondary research, including literature review and through case study. The stakeholder’s behavioural needs towards acting and implementing sustainable practices led to the adoption of sustainable practices within projects which are managed across profit and non-profit organisations. Nevertheless, lack of sustainable behaviour was outlined, and henceforth the integration of sustainable development within social projects is crucially important as such projects were identified as the drivers toward educating the society in order to help to produce generations of people who would be more sustainably aware. Currently, sustainable development is very often taken into account when it comes to managing projects. Nevertheless, if the adoption of sustainable practices is well established in some sectors such as construction, literature tends to demonstrate a lack of information regarding other sectors, especially within social projects. This research aims to investigate the adoption of sustainable practices within social projects and therefore to satisfy a literature gap.

    A numerical model is presented that defines a sustainability criterion as no net loss of shell, and calculates a sustainable harvest of seed (<75 mm) and sack or market oysters (≥75 mm). Stock assessments of the Primary State Seed Grounds conducted east of the Mississippi from 2009 to 2011 show a general trend toward decreasing abundance of sack and seed oysters. Retrospective simulations provide estimates of annual sustainable harvests. Comparisons of simulated sustainable harvests with actual harvests show a trend toward unsustainable harvests toward the end of the time series. Stock assessments combined with shell-neutral models can be used to estimate sustainable harvest and manage cultch through shell planting when actual harvest exceeds sustainable harvest. For exclusive restoration efforts (no fishing allowed), the model provides a metric for restoration success-namely, shell accretion. Oyster fisheries that remove shell versus reef restorations that promote shell accretion, although divergent in their goals, are convergent in their management; both require vigilant attention to shell budgets.

    2016-03-01

    Full Text Available Logging residues are often utilized as a Best Management Practice (BMP for stabilizing bare soil on forest harvesting operations. As utilization of woody biomass increases, concern has developed regarding availability of residues for implementing BMPs. The Virginia Department of Forestry (VDOF inspects all logging operations in Virginia and randomly selects a portion of harvests for more intensive audits. The VDOF BMP audit process intensively evaluates implementation of BMPs in seven categories (84 specific BMPs on 240 sites per year. This research analyzed three years of audit data (2010–2012 to quantify differences in BMP implementation between biomass and conventional harvesting operations. Among 720 audited tracts, 97 were biomass harvests, with 88 occurring in the Piedmont region. Only the streamside management zone (SMZ category had significant implementation percentage differences between biomass (83.1% and conventional harvests (91.4% (p = 0.0007 in the Piedmont. Specific areas where biomass harvesting operations had lower implementation were generally not related to a lack of residues available for implementing BMPs, but rather were from a lack of appropriate SMZs, overharvesting within SMZs, or inadequate construction of roads, skid trails, and stream crossings. Existing BMP recommendations already address these areas and better implementation would have negated these issues.

    Miombo woodlands play an important role in the livelihood of people living in sub-equatorial African countries, contributing to satisfy basic human needs such as food, medicine, fuelwood and building materials. However, over-exploitation of plant resources and unsustainable harvest practices can potentially degrade forests. The aim of this study was to document the use of Miombo plant products, other than medicinal plants, in local communities, within a wider framework in which we discussed possible links between traditional uses and conservation status of the used species and of the whole Miombo environment. Fieldwork took place in four communities of Muda-Serração, central Mozambique. We conducted semi-structured interviews with 52 informants about their knowledge, use and harvesting practices of useful plants. A survey on local Miombo vegetation was also carried out in order to assess abundance and distribution of useful woody plants cited in the interviews in areas exposed to different exploitation rates. A Conservation Priority index was also applied to rank conservation values of each used woody species. Ninety-eight plants cited by the informants were botanically identified. The most relevant general category was represented by food plants (45 species), followed by handicraft plants (38 species) and domestic plants (37 species). Among the 54 woody species observed in vegetation plots, 52% were cited as useful in the interviews. Twenty-six woody species found in 'natural' Miombo areas were not found in 'degraded' ones: of these, 46% were cited in the interviews (58% in the food category, 50% in the handicraft category, 25% in the domestic category and 8% in the fishing category). Results of conservation ranking showed that 7 woody species deserve conservation priority in the investigated area. This study shows that the communities investigated rely heavily on local forest products for their daily subsistence requirements in food, firewood/charcoal and

    Full Text Available Coastal tourism destinations are reinventing themselves, concentrating on product improvement and image enhancement. Reinventing sustainably is key and restaurants are an important factor. Research upon the processes of change in the industry seems to be fragmented and undefined in its conclusions. Knowledge is lacking on what specifically drives innovation in the hospitality industry. Since restaurants seem to be focusing more than ever on implementing green strategies, incorporating sustainability into restaurant practices is not an unexplored area. However, the how and why it is incorporated or not, can be different per restaurant. The objective of this study is to identify possibilities of change in restaurateur practices, which can lead to interventions that will foster sustainable destination development in Vrouwenpolder; a coastal destination within the Netherlands. For the identification of interventions that could advance the sustainability enacted in restaurateur practices, a qualitative research was conducted. Practices of restaurateurs in Vrouwenpolder are identified and compared to perceived-to-be ideal practices. Analysis of data collection draws on practice theory, and resulted into recommendations for advancing the sustainability enacted in restaurateur practices. It seems to be that primarily the meaning within a practice is decisive in whether sustainability is integrated or not.

    Harvesting energy from nonconventional sources in the environment has received increased attention over the past decade from researchers who study these alternative energy sources for low power applications. Although that energy harvested is small and in the order of milliwatt, it can provide enough power for wireless sensors and other low-power applications. In the environment there is a lot of wasted energy that can be converted into electricity to power the various circuits and represents a potentially cheap source of power. Energy harvesting is important because it offers an alternative power supply for electronic devices where is does not exist conventional energy sources. This technology applied in a wireless sensor network (WSN) and devices on the IoT, will eliminate the need for network-based energy and conventional batteries, will minimize maintenance costs, eliminate cables and batteries and is ecological. It has the same advantage in applications from remote locations, underwater, and other hard to reach places where conventional batteries and energy are not suitable. Energy harvesting will promote environmentally friendly technologies that will save energy, will reduce CO2 emissions, which makes this technology indispensable for achieving next-generation smart cities and sustainable society. In response to the challenges of energy, in this article we remind the basics of harvesting energy and we discuss the various applications of this technology where traditional batteries cannot be used.

    Full Text Available he study aimed to determine the relationship between teachers’ integ ration of environmental awareness and level of sustainable development practices of selected public high schools in the First District of Oriental Mindoro. Using the descriptive correlational and comparative studies, the questionnaires were distributed to 384 students. The study found out that the teachers integrated environmental awareness topics on waste management, pollution, forest conservation and climate change on their class lessons; the schools were practicing proper waste disposal, recycling, compo sting, tree planting and energy conservation for sustainable development practices. Teachers’ integration of environmental awareness influences sustainable development practices. This integration and practices can be enhanced by reaching out to communities outside the school and by strengthening the established linkage s to other environment - related agencies in order to achieve sustainability. It means amplifying by extending sustainable practices as collaborative effort of the students, schools, outside com munities, LGU’s and other related government and nongovernment agencies. Such interaction can improve the quality and coverage of sustainable pr actices not only in school but i n the whole community.

    While sustainability is a key concept in many different domains today, it has not yet been sufficiently emphasized in the healthcare sector. Earlier research shows that ethical values and evidence-based care models create sustainability in care practice. The aim of this study was to gain further understanding of the ethical values central to the realization of sustainability in care and to create an ethical practice model whereby these basic values can be made perceptible and active in care practice. Part of the ongoing "Ethical Sustainable Caring Cultures" research project, a hermeneutical application research design was employed in this study. Dialogues were used, where scientific researchers and co-researchers were given the opportunity to reflect on ethical values in relation to sustainability in care. An ethical practice model with ethos as its core was created from the results of the dialogues. In the model, ethos is encircled by the ethical values central to sustainability: dignity, responsibility, respect, invitation, and vows. The model can be used as a starting point for ethical conversations that support carers' reflections on the ethical issues seen in day-to-day care work and the work community, allowing ethical values to become visible throughout the entire care culture. It is intended as a tool whereby carers can more deeply understand an organization's common basic values and what they entail in regard to sustainability in care.

    The creation of a sustainable future depends on the knowledge and involvement of the people, as well as an understanding of the consequences of individual actions. To implement sustainable construction effectively, the construction practitioners must be willing to change their behaviour in exploring new territory and willing to adopt new products, ideas and practices. In Malaysia, the issues of environmental dissatisfaction on construction projects regularly appeared in headlines. These negative remarks about construction tainted the good image of the industry. Due to the growing concern on environment, the government, professional bodies and private companies are beginning to take proactive approach to reduce this problem without restraining the need for development. There is some evidence of sustainable projects being built in Malaysia indicating that the concept of sustainable construction has beginning to settle within the industry. However, these projects are pioneers and merely fingers count. As global interest on sustainability has steadily blooming, Malaysia should not fell short in its attitude on sustainability and sustainable construction. Are we ready to make our commitment for sustainability in the global market? This paper focuses on the actions undertaken by the Malaysian government, non-government organisations and construction players in promoting sustainability in construction. To ensure that those concerted efforts are not only skin deep in its impact, a survey was conducted to investigate the awareness of the developers regarding this issue and whether those developers has absorb the concept of sustainable construction in their current practices. The survey revealed that although the developers are aware of the rising issues on sustainability, little efforts are generated from the developers in implementing it. More effort is necessary to boost this application and further stimulate actions and strategies towards a sustainable built environment.

    2017-04-01

    Intelligent tires are essentially a data acquisition system based on a number of complex intelligent sensors inside the tire. Intelligent tires which are capable of boosting the performance of the vehicle have the key problem of energy supply. A practical energy harvester was here designed to support the electric equipment in the intelligent tires and make it feasible for them to work steadily and constantly. This harvester takes the centrifugal force caused by the rotation of the wheel, which could affect the resonance frequency of the piezoelectric cantilever, into account. First, the vibration characteristics of the wheel were analyzed by road test, and the optimal arrangement for vibration energy usage was determined. Then, a piezoelectric vibration energy harvester was designed according to a series of formulas that took the effect of centrifugal force on resonance frequency into account. Finally, a road test was carried out to test the generated energy of the energy harvester excited by the vibration of the wheel. The results showed that the electric power meets the need of general low-power consumption triaxial accelerometers used in intelligent tires.

    The ability of the earth to sustain health among humans and in the natural world is under threat from overpopulation, environmental degradation, and climate change. These global threats are anticipated to harm health and human occupation in many direct and indirect ways. Strategies are needed to mitigate the effects of these threats and to build individual and community capacities to foster resilience. This paper links issues of sustainability with occupational therapy philosophy and discusses how employing a sustainability lens with professional reasoning can help practitioners integrate sustainability into their practice. Human occupation is inseparable from the environments in which people live. Human occupation has caused the current environmental crisis, and targeted human action is required to safeguard future health and well-being. Occupational therapists have an ethical obligation to use professional reasoning strategies that, taken collectively, can help to build a sustainable and resilient future.

  2. Sustainable urban water supply in south India: Desalination, efficiency improvement, or rainwater harvesting?

    Srinivasan, Veena; Gorelick, Steven M.; Goulder, Lawrence

    2010-10-01

    Indian megacities face severe water supply problems owing to factors ranging from growing population to high municipal pipe leakage rates; no Indian city provides 24/7 water supply. Current approaches to addressing the problem have been "utility centric," overlooking the significance of decentralized activities by consumers, groundwater extraction via private wells, and aquifer recharge by rainwater harvesting. We propose a framework that makes it possible to evaluate a wider range of centralized and decentralized policies than previously considered. The framework was used to simulate water supply and demand in a simulation model of Chennai, India. Three very different policies, supply augmentation, efficiency improvement, and rainwater harvesting, were evaluated using the model. The model results showed that none of the three policies perfectly satisfied our criteria of efficiency, reliability, equity, financial viability, and revenue generation. Instead, a combination of rainwater harvesting and efficiency improvement best meets these criteria.

    Full Text Available With the emergence of environmental protection as a global issue, implementing environmental practices for sustaining green supply chain management (GSCM has received a lot of attention. This study investigates the impact of integration with suppliers and supply disruption risk on environmental practices. It also examines the role of supplier integration and supply disruption risk on performance. Finally, it investigates the relationship between environmental practices and performance in order to sustain green supply chains. Based on 272 survey responses from supply and purchase managers, our research results support the positive impact of integration with suppliers and the negative impact of supply disruption risk on the adoption of environmental practices. Furthermore, they provide empirical evidence that environmental practices and integration with suppliers are positively associated with performance, while supply disruption risk is negatively associated with performance. This study identifies antecedents and establishes a research framework of GSCM. More importantly, it provides meaningful insights to managers regarding the implementation of environmental practices related to other supply chain practices for sustaining green supply chains.

  7. Renewal of Collaborative Research: Economically Viable Forest Harvesting Practices That Increase Carbon Sequestration

    Forests provide wildlife habitat, water and air purification, climate moderation, and timber and nontimber products. Concern about climate change has put forests in the limelight as sinks of atmospheric carbon. The C stored in the global vegetation, mostly in forests, is nearly equivalent to the amount present in atmospheric CO{sub 2}. Both voluntary and government-mandated carbon trading markets are being developed and debated, some of which include C sequestration resulting from forest management as a possible tradeable commodity. However, uncertainties regarding sources of variation in sequestration rates, validation, and leakage remain significant challenges for devising strategies to include forest management in C markets. Hence, the need for scientifically-based information on C sequestration by forest management has never been greater. The consequences of forest management on the US carbon budget are large, because about two-thirds of the {approx}300 million hectare US forest resource is classified as 'commercial forest.' In most C accounting budgets, forest harvesting is usually considered to cause a net release of C from the terrestrial biosphere to the atmosphere. However, forest management practices could be designed to meet the multiple goals of providing wood and paper products, creating economic returns from natural resources, while sequestering C from the atmosphere. The shelterwood harvest strategy, which removes about 30% of the basal area of the overstory trees in each of three successive harvests spread out over thirty years as part of a stand rotation of 60-100 years, may improve net C sequestration compared to clear-cutting because: (1) the average C stored on the land surface over a rotation increases, (2) harvesting only overstory trees means that a larger fraction of the harvested logs can be used for long-lived sawtimber products, compared to more pulp resulting from clearcutting, (3) the shelterwood cut encourages growth of

    Full Text Available Today, people often talk about biologic agriculture and Integrated Production (IP, even if the real meaning of these terms is altered. In both cases, they deal with production methods characterized by a particular attention to the reduction of the environmental impact of all the farm practices used, especially for defence from adversities, being the element of major concern for environment and consumers’ health.Farm practice evolution, especially those about pest defence, is based on important conceptual change, accurate scientific analysis and organization of technical assistance, rationalization of agri-pharmaceutical product use is one of the main objective of Integrated Production Specifications (IPS. The quantitative reduction is the first objective, obtained by various means such as the use of efficient equipment and the qualitative selection based on the priority use of minor impact means, effectiveness being equal. At post-harvest, the anti-parasitary defence is undergoing deep changes in our country. Once, pesticides very toxic and persistent were used; however, in the last years the availability of active principles (a.p. usable on foodstuffs or in productive environments; for instance, methyl bromide use has been progressively reduced till its banishment because it is recognized to damage the ozone layer. Thus, on the whole we can talk about “integrated pest management” even for the post-harvest sector. However, substantial differences exist between agriculture and post-harvest, thus the integrated pest management in food production environment has to be designed in a different way. The fundamental element of this technique is to identify a tolerance threshold to pest attack but for the defence of food industries and stored foodstuffs is very difficult, if not impossible, to fix a limit to insect presence after which intervening is compulsory. Monitoring of pest attacks and the implementation of prevention practices is

    Strategically leveraging health and safety initiatives with sustainability and stewardship helps organizations improve profitability and positively impact team member and customer attachment to the organization. Collective efficacy enhances the triple bottom line: healthy people, healthy planet, and healthy profits. The HS(3)™ Best Practice Exchanges group demonstrated that collective efficacy can leverage the social cohesion, communication channels, and activities within workplaces to promote a healthy, sustainable work culture. This in turn (1) protects the health and safety of workers, (2) preserves the natural environment, and (3) increases attachment to the organization. Community-based participatory research using the Attach21 survey assessed the progress of these companies in their efforts to integrate health, safety, sustainability, and stewardship. Monthly Best Practice Exchanges promoted collective efficacy by providing support, encouragement, and motivation to share and adopt new ideas. Copyright 2013, SLACK Incorporated.

    Land is not only a critical component of the earth's life support system, but also a precious resource and an important factor of production in economy. However, historical industrial operations have caused a huge stockpile of contaminated land that is only slowly being remediated. After several decades of clean-up efforts, there are still an estimated 294,000 contaminated sites in the US and over 300,000 hectares of potentially contaminated land in the UK. It is imperative to develop technical solutions as well as socioeconomic and political instruments to achieve sustainable restoration of contaminated land. The inclusion of sustainability in decision making provides an opportunity to integrate a wide range of considerations: risk control, brownfield regeneration, carbon footprint, water footprint, renewable energy, etc. This study explores the behavior patterns and driving forces behind sustainable practices in remediation, aiming at advancing our understanding of the fundamental relationships among changing natural and manipulated geological environments, sustainability, and technology choices. A large-scale survey is being conducted in the US and UK to study behaviour and decision making issues from a stakeholder perspective. Historically stakeholder theories have been extensively applied to study organization management issues in the academia. This study intends to apply stakeholder theories to engineering practice and sustainability science studies. Pilot test results found that sustainability considerations are widely adopted and in a wide variety of ways. Site owners and regulators are found to be most influential in the decision making process. There is no lack of incentives to adopt sustainability practices, but various factors, such as lack of resources and cost considerations, are still considered impeding factors. At the time of the 2012 AGU meeting, further results from the survey will be available.

    Singer, E.; Gonzalez, J.; Juenger, T. E.; Woyke, T.

    2016-12-01

    Growing energy demands and concerns for climate change have urgently pushed forward the timeline for the implementation of biofuel energies. Switchgrass (Panicum virgatum) is a leading biofuel crop in the United States. Bacteria living on and inside leaves and roots affect plant health, hence a plant's genetic control over its microbiota is of great interest to crop breeders and evolutionary biologists. We present a large-scale field experiment to untangle the effects of genotype, environment, soil horizon and harvest treatment practices on prokaryotic and fungal communities associated with leaves and roots of switchgrass. Using V4 16S rRNA and ITS gene as well as metagenome sequencing, we show that host genotype is significant in both, leaves and roots, and varies among sites. Microbiome composition along the rhizosphere also shifts with soil depth. Furthermore, plant harvest significantly changes both, leaf surface and rhizosphere communities, which can be seen a year after the harvest event. Gene function analysis shows that rhizosphere communities are enriched in genes encoding nitrate reduction, carbohydrate transport and metabolism, motility, and sensory and signal transduction proteins relative to leaf surface communities. Our results demonstrate how genotype-environment interactions contribute to the complexity of microbiome assembly in natural environments.

  18. Green dentistry: the art and science of sustainable practice.

    Science.gov (United States)

    Mulimani, P

    2017-06-23

    Dentistry is highly energy and resource intensive with significant environmental impact. Factors inherent in the profession such as enormous electricity demands of electronic dental equipment, voluminous water requirements, environmental effects of biomaterials (before, during and after clinical use), the use of radiation and the generation of hazardous waste involving mercury, lead etc have contributed towards this. With rising temperatures across the world due to global warming, efforts are being made worldwide to mitigate the effects of environmental damage by resorting to sustainability concepts and green solutions in a myriad of ways. In such a scenario, a professional obligation and social responsibility of dentists makes it imperative to transform the practice of dentistry from a hazardous to a sustainable one, by adopting environmental-friendly measures or 'green dentistry'. The NHS in the UK has been proactive in implementing sustainability in healthcare by setting targets, developing guidance papers, initiating steering groups to develop measures and implementing actions through its Sustainable Development Unit (SDU). Such sustainable frameworks, specific to dentistry, are not yet available and even the scientific literature is devoid of studies in this field although anecdotal narratives abound. Hence this paper attempts to present a comprehensive evaluation of the existing healthcare sustainability principles, for their parallel application in the field of dentistry and lays out a blueprint for integrating the two main underlying principles of sustainability - resource use efficiency and eliminating or minimising pollution - in the day-to-day practice. The article also highlights the importance of social values, community care, engaging stakeholders, economic benefits, developing policy and providing leadership in converting the concept of green dentistry into a practised reality.

  19. A review of sustainable facilities management knowledge and practice

    Baaki Timothy Kurannen

    2016-01-01

    Full Text Available Sustainability is seen as a far-reaching issue now, and one which the facilities management [FM] profession cannot overlook. This paper explores current sustainable facilities management [SFM] knowledge and practice with specific focus on performance as part of a research focus toward proposing a sustainable FM performance management framework for sustainable healthcare waste management in Malaysia. This paper utilized a review of extant literature on the subject of SFM, FM performance and FM development in Malaysia as source of information. Findings reflect the increasing recognition of the need for the strategic FM function, and how facilities managers are best positioned to drive organizations’ sustainability agendas. In Malaysian context, this recognition is barely evident as findings show FM practice is still immature and predominantly operational. Unlike developed FM markets, FM relevance in Malaysia is being driven by the public sector. Also findings show a disharmony between organizations’ sustainability priority areas and the responsibilities for facilities managers to execute them where the sustainability policy of organizations prioritize one FM service and the facilities managers’ responsibilities prioritize another. As most of SFM implementation is driven by legislation this seems to strengthen the position that, organizations continue to view support services as non-value-adding, as unavoidable liabilities. The implication of this is the pressure on the FM function to continually express its strategic relevance to organizations by tangible value-adding performance output. This creates a new perspective to measuring and managing facilities performance. This paper therefore elevates the importance of FM performance management in SFM context taking into account the peculiar position of the facilities manager. This is seen as a way forward for FM to better express its value to the organization

  20. Smallholder farmers' behavioural intentions towards sustainable agricultural practices.

    2017-02-01

    The introduction of sustainable practices is considered a win-win strategy for low-income countries because of its potential to simultaneously improve food security and address environmental issues. Despite the numerous studies that focus on the adoption of technological innovations, little work has been done on the socio-psychological behaviour of farmers with regard to sustainable practices. This study investigates smallholder farmers' intentions towards two practices: minimum tillage and row planting. The decomposed theory of planned behaviour is used as a theoretical framework to analyse the intentions. The findings reveal that attitudes and normative issues positively explain farmers' intentions to adopt both practices. Perceived control also has a positive significant effect on the intention to apply minimum tillage. When the intention is formed, farmers are expected to carry out their intention when opportunities arise. Moreover, perceived usefulness, social capital, and perceived ease of operation are also significant predictors of farmers' attitudes. Furthermore, social capital and training are factors that positively affect the normative issue, which in turn also positively mediates the relationship between training, social capital and intention. Finally, it is shown that neither the perceived resources nor information from the media significantly affect farmers' intentions. This paper thus confirms that social capital, personal efficacy, training and perceived usefulness play significant roles in the decision to adopt sustainable practices. In addition, willingness to adopt seems to be limited by negative attitudes and by weak normative issues. Therefore, to improve adoption of sustainable practices by smallholder farmers, attention should be given to socio-psychological issues. This could lead to improvements in farm productivity and enhance the livelihoods of smallholders. Copyright © 2016 Elsevier Ltd. All rights reserved.

  1. Farmer’s motivation to adopt sustainable agricultural practices

    Directory of Open Access Journals (Sweden)

    Davide Menozzi

    2015-09-01

    Full Text Available The 2014-2020 Common Agricultural Policy (CAP reform defines new rules for farmers including maintenance of the ecological focus area (EFA. Sustainability is also a requirement to meet consumer expectations and a competitive advantage for firms. This paper aims to evaluate the farmers’ intention to implement sustainable practices related to the EFA measure and to the private sustainability schemes proposed by the food industry. The Theory of Planned Behaviour (TPB was applied on a sample of durum wheat producers to analyse intentions 1 to maintain 7% of the arable land as an EFA, and 2 to implement the private sustainability scheme. Structural equation modelling was applied to test for the relative importance of intention determinants. The farmers’ attitude and past behaviour positively affect intentions to implement the EFA, while perceived behavioural control and attitudes predict intentions to adopt the private sustainability scheme. These results suggest possible interventions that public authorities and supply chain leaders might implement to stimulate farmers’ sustainable behaviours.

As just 1% of buildings in the European Union have been built since 2006, it is essential to turn towards refurbishment of existing buildings if goals of sustainable development are to be achieved. Therefore, this article explores the ways in which sustainable development in construction is encouraged and achieved, especially concentrating on architectural heritage buildings. The idea of sustainable development revolves solely around carbon emissions, and therefore, historic buildings in Europe face the key issue of sustainability. Recently, there has been an increasing interest in reusing existing buildings through refurbishment and adaptive reuse where possible, as building reuse should offer environmental savings over demolition and new construction. In addition, despite popular belief, older buildings are capable of adapting to the new energy efficiency norms. This study explores the possibilities of encouraging complete refurbishment (including both sustainable renovation and strengthening of historical buildings by exploring incentives used in Europe, the USA, Canada and New Zealand. Based on the literature review and best practices, the article concludes with recommendations on how to increase the positive investment flow of private capital into architectural heritage buildings, thus ensuring both preservation of heritage and achievement of sustainable development goals. The findings help both the user of the initiative on gaining insight into the intervention process that can be expected, as well as the local and regional governments interested in boosting adaptive reuse and refurbishment of existing buildings in order to achieve sustainable development goals.

    Objective. To describe best practices, necessary resources, and success or lessons learned from established consortia in pharmacy education. Methods. Using semi-structured interviews and qualitative analysis, interviews with members of established consortia in pharmacy education were conducted until saturation was reached. Themes were analyzed and meaningful descriptions of consortia characteristics were developed using systematic text condensation. Results. Thirteen interviews were conducted. The primary purpose for forming a consortium was identified as threefold: share ideas/best practices; facilitate collaboration; and perform shared problem-solving. For experiential education consortia, two additional purposes were found: share capacity for practice sites, and promote standardization across programs. When investigating best practices for established consortia, three main themes were identified. These included strategies for: (1) relationship building within consortia, (2) successful outcomes of consortia, and (3) sustainability. Successful outcomes included scholarship and, sometimes, program standardization. Sustainability was linked to structure/support and momentum. Respect was considered the foundation for collaborative relationships to flourish in these consortia. Conclusions. Pharmacy education consortia form through a process that involves relationship building to produce outcomes that promote sustainability, which benefits both pharmacy schools and individual faculty members. Consortium formation is a viable, productive, and often necessary institutional goal for pharmacy schools.

    Full Text Available This article’s primary objective is to unfold how teachers translate education for sustainable development (ESD in a school context. The article argues that exploring tensions, ruptures and openings apparent in this meeting is crucial for the development of existing teaching practices in relation to ESD. The article draws on doctoral research involving interviews with researchers and teachers who have collaborated in ESD research and development projects at primary and secondary schools in two different countries, Denmark and Ireland. It is the teachers’ perspectives on the projects which form the analytical foundation; thus, it is the practices as seen from the ‘inside’. Furthermore, ESD practices are considered in a broader societal perspective, pointing to the critical power of the practice lens.

    2014-06-01

    Full Text Available The wood of the palm Iriartea deltoidea is an excellent material used for building, furniture and handicrafts in the Colombian Amazon, especially in the Amazon foothills where a small industry has developed around this species. We report the management practices, uses and commercial trends of this species in the municipality of Mocoa (Putumayo. We present data on population structure at three contrasting sites. The estimated demand of stems is ca. 750 per year, and the area necessary to supply them is 17-83 ha. Harvesting is carried out in natural forests or in pastures. The management practices are selective logging, sowing of seedlings and sparing of palms in pastures. Taking into account the natural condition of Mocoa, the abundance of the species, its growth rate and the current extraction system, productivity could grow if the followings activities were performed: enrichment of secondary forests, re-population of eroded areas, reduction of deforestation, and establishment of minimal harvest sizes based on height rather than diameter.

    2016-08-01

    In many areas of the world, groups of people have attempted to create urban landscapes that follow the principles of environmental sustainability. To this end, groups have devised alternative models, such as ecovillages, where low-impact handling is used and a way of life different from that of large population centers is adopted. Although these villages exist, their efficiency in the conservation of natural resources has not been effectively evaluated. This study evaluated the practices used by two Brazilian ecovillages to conserve water resources to assess whether this new concept of living is indeed successful in meeting sustainability goals. We selected 25 indicators of water sustainability, and using the compromise programming method, we quantified the distance between those landscapes self-referenced as sustainable and an ideal hypothetical scenario. We also interpreted the communities perceptions using the distance between the current situations and the envisioned scenario. We concluded that both ecovillage are far from technically ideal scenario, but the communities have a strong sense of their limitations in implementing water resources conservation. The communities attributed this fact primarily to deficiencies in the shared management.

    Full Text Available The conception of sustainable development has been implemented into practice in numerous economic sectors, including forestry. Forest ecosystems are extremely important in the global ecological system, therefore maintenance and appropriate management of forest resources according to sustainable development principles have engaged a great deal of attention. The concept of sustainable forest management (SFM encompasses three dimensions: ecological, economic and social. A powerful tool to promote SFM are criteria and indicators. The aim of the article was evaluation of SFM in Poland, using one of the methods proposed by the Food and Agriculture Organization (FAO. According to data available, Polish forestry has a number of advantages: Poland has avoided the problem of deforestation, forest area has been permanently increasing, there has been observed improvement of forest health and vitality as well as a significant share of forests has carried out protective functions with no impact on timber production. Poland’s model of SFM is an adaptive process of balancing the ever-changing set of economic, environmental and social expectations. Such a complicated undertaking requires constant assessing and adjusting forest practices, in response to new circumstances, scientific advances and societal input

    Full Text Available The first objective of this paper was to provide an inventory of developments of certification schemes for sustainable biomass production, following recent EU legislation (both formalized and under development. One main pillar is the EU Timber Regulation for legal harvesting; a second one is the EU’s 2010 recommendations for sustainable woody biomass sourcing for energy; the third one is the EU Waste Directive. The second objective was to benchmark the coverage of this (draft legislation, when wood product certificates for sustainable forest management (SFM are used as proof of the related legislative requirements. We studied North America, as it is a major biomass supplier to the EU-28. Together with existing forest legislation in the US and Canada, SFM certificates are actively used to cover the EU’s (draft legislation. However, North American forests are only partially certified with fibers coming from certified forests; these are referred to as forest management (FM fibers. Other certified fibers should come from complementary risk assessments downstream in the supply chain (risk based fibers. Our benchmark concludes that: (a FM fiber certification by the Forest Stewardship Council (FSC and the Program for the Endorsement of Forest Certification (PEFC international standards show the highest level of coverage with EU’s (draft legislation; (b There is insufficient coverage for risk based fibers by FSC Controlled Wood (FSC-CW, PEFC Due Diligence (PEFC-DD, or SFI-fiber sourcing (SFI-FS. Other weaknesses identified for elaboration are: (c Alignment in definitions are needed, such as for primary forest, high carbon stock, and wood waste (cascading; (d Imperfect mass balance (fiber check downstream needs to be solved, as non-certified fiber flows are inadequately monitored; (e Add-on of a GHG calculation tool is needed, as GHG life cycle reporting is not covered by any of the SFM frameworks.

    2015-01-01

    Until recently it was believed that photosynthesis, a fundamental process for life on earth, could be fully understood with semi-classical models. However, puzzling quantum phenomena have been observed in several photosynthetic pigment-protein complexes, prompting questions regarding the nature and role of these effects. Recent attention has focused on discrete vibrational modes that are resonant or quasi-resonant with excitonic energy splittings and strongly coupled to these excitonic states. Here we report a series of experiments that unambiguously identify excited state coherent superpositions that dephase on the timescale of the excited state lifetime. Low energy (56 cm-1) oscillations on the signal intensity provide direct experimental evidence for the role of vibrational modes resonant with excitonic splittings in sustaining coherences involving different excited excitonic states at physiological temperature.

  16. How to harvest brainpower for a brighter future on Earth - bypassing stereotypes in practice

    2016-04-01

    Our ability to detect and respond to patterns, the core asset in scientific work, likely has been a strong evolutionary advantage when navigating between need and danger. We therefore argue that our use of stereotypes for the most part is decoupled from malice but instead profoundly rooted, pervasive and often unchallenged in our daily thought process. The fundamental need for patterns also means that we all express biases - regardless of our gender - such as during teaching, mentoring or collaborations. As culprits, our implicit bias both disfavor (e.g. female or immigrant students) and favor (e.g. the-celebrated-worker's-results-are-probably-stronger-than-they-seem) our fellow workers in unsolicited ways. Additionally, people in our environment adapt to the expectations we express, called the stereotype threat. Ultimately, these two effects likely lead to missed opportunities for new questions and achievements. The omni-present implicit bias also means that some equality efforts, such as quotas, would soon be neutralized unless we train in catching our use of stereotypes in action. We will share our experiences from gender sensitivity training during teaching and assessment, such as the use of anonymous exams, simple 'traps' to demonstrate gender bias, and group work management. We also present views collected in our group on how academic talent management may improve through mentorship, career coaching and general policy decisions. All with the selfish ambition to improve future harvests of brainpower, for science and for sustainable human life on Earth.

    Urban rainwater management need to achieve an optimal compromise among water resource augmentation, water loggings alleviation, economic investment and pollutants reduction. Rainwater harvesting (RWH) systems, such as green rooftops, porous pavements, and green lands, have been successfully implemented as viable approaches to alleviate water-logging disasters and water scarcity problems caused by rapid urbanization. However, there is limited guidance to determine the construction areas of RWH systems, especially for stormwater runoff control due to increasing extreme precipitation. This study firstly developed a multi-objective model to optimize the construction areas of green rooftops, porous pavements and green lands, considering the trade-offs among 24 h-interval RWH volume, stormwater runoff volume control ratio (R), economic cost, and rainfall runoff pollutant reduction. Pareto fronts of RWH system areas for 31 provinces of China were obtained through nondominated sorting genetic algorithm. On the national level, the control strategies for the construction rate (the ratio between the area of single RWH system and the total areas of RWH systems) of green rooftops (ηGR), porous pavements (ηPP) and green lands (ηGL) were 12%, 26% and 62%, and the corresponding RWH volume and total suspended solids reduction was 14.84 billion m3 and 228.19 kilotons, respectively. Optimal ηGR , ηPP and ηGL in different regions varied from 1 to 33%, 6 to 54%, and 30 to 89%, respectively. Particularly, green lands were the most important RWH system in 25 provinces with ηGL more than 50%, ηGR mainly less than 15%, and ηPP mainly between 10 and 30%. Results also indicated whether considering the objective MaxR made a non-significant difference for RWH system areas whereas exerted a great influence on the result of stormwater runoff control. Maximum daily rainfall under control increased, exceeding 200% after the construction of the optimal RWH system compared with that before

    Little is known regarding sustainability of evidence-based practices (EBPs) following implementation. This article reports sustainability of evidence-based acute pain management practices in hospitalized older adults following testing of a multifaceted Translating Research Into Practice (TRIP) implementation intervention. A cluster randomized trial with follow-up period was conducted in 12 Midwest U.S. hospitals (six experimental, six comparison). Use of evidence-based acute pain management practices and mean pain intensity were analyzed using generalized estimating equations across two time points (following implementation and 18 months later) to determine sustainability of TRIP intervention effects. Summative Index scores and six of seven practices were sustained. Experimental and comparison group differences for mean pain intensity over 72 hours following admission were sustained. Results revealed most evidence-based acute pain management practices were sustained for 18 months following implementation. Further work is needed to identify factors affecting sustainability of EBPs to guide development and testing of sustainability strategies.

    Full Text Available Purpose: The objective of the present study is to select some feasible and sustainable logistic practices in order to improve the urban freight distribution in Bilbao city. Design/methodology/approach: After a thorough literature review and a benchmarking, Analytic Hierarchy Process (AHP techniques were used in order to support the decision making processes in order to select the most interesting practices. The criteria used for this selection were based on four factors: (1 improvement of the city freight distribution, (2 implementation possibility, (3 short and medium term applicability and (4 impact on the citizens of Bilbao. Findings: The paper identifies some specific problems that must be faced during the last stage of the logistics chain, where products are usually delivered to final customers in the urban environment. Research limitations/implications: Not all good urban freight distribution practices can be applied universally to all types of towns. Therefore, it is necessary to design some practices specifically to each particular city according to the physical characteristics of the city, the companies’ motivation and the citizens’ habits. Practical implications: All the agents involved in the city freight distribution should be aware of the benefits and problems that their actions cause. Originality/value: This study was carried out from a wide perspective that included researchers, logistics operators and local authorities.

    2016-12-01

    Full Text Available This article explores the possibility of incorporating traditional water management experiences into modern water management. After the literature review, two case studies are presented from Borana and Konso communities in southern Ethiopia. The study was conducted through interviews, discussions, and observations. The two cases were selected due to their long existence. Both communities have their own water source types, depending on local hydrogeological conditions. Borana is known for the so-called Ella (wells and Konso for Harta (ponds, which have been managed for more than five centuries. All government and development partners strive to achieve sustainable services in water supply and sanitation. Therefore, they design various management packages to engage the communities and keep the systems sustainable. However, the management components are often designed with little attention to local customs and traditions. The cases in the two communities show that traditional knowledge is largely ignored when replaced by modern one. However, the concepts of cost recovery, ownership experience, equity, enforcement, integrity, and unity, which are highly pronounced in modern systems, can also be found in the traditional water managements of Borana and Konso. Naturally, one shoe never fits all. Borana and Konso experiences are working for their own community. This research implies that when we plan a project or a program for a particular community, the starting point should be the indigenous practices and thoughts on life.

    Roof-harvested rainwater (RHRW) is an important alternative source of water that many island communities can use for drinking and other domestic purposes when groundwater and/or surface water sources are contaminated, limited, or simply not available. The aim of this pilot-scale study was to investigate current RHRW practices in American Samoa (AS) and to evaluate and compare the quality of water from common potable water sources including RHRW stored in tanks, untreated stream water, untreated municipal well water, and treated municipal tap water samples. Samples were analyzed using culture-based methods, quantitative polymerase chain reaction (qPCR), and 16S amplicon sequencing-based methods. Based on indicator bacteria (total coliform and Escherichia coli) concentrations, the quality of RHRW was slightly lower than well and chlorinated tap water but exceeded that of untreated stream water. Although no Giardia or Leptospira spp. were detected in any of the RHRW samples, 86% of the samples were positive for Cryptosporidium spp. All stream water samples tested positive for Cryptosporidium spp. Opportunistic pathogens (Pseudomonas aeruginosa and Mycobacterium intracellulare) were also detected in the RHRW samples (71 and 21% positive samples, respectively). Several potentially pathogenic genera of bacteria were also detected in RHRW by amplicon sequencing. Each RHRW system was characterized by distinct microbial communities, 77% of operational taxonomic units (OTUs) were detected only in a single tank, and no OTU was shared by all the tanks. Risk of water-borne illness increased in the following order: chlorinated tap water/well water water. Frequent detection of opportunistic pathogens indicates that RHRW should be treated before use. Stakeholder education on RHRW system design options as well as on importance of regular cleaning and proper management techniques could improve the quality of the RHRW in AS.

    In the past twenty years, various sustainable urban development policies and methods had been implemented within China, such that sustainable urbanization is now more widely accepted. Some of these policies and methods have been found to be successful in improving the sustainability of cities in China. Those practices can be defined as the best practices of sustainable urbanization, which can provide useful references for future urban developments. However, few existing studies examine how to learn from these best practices.

    Full Text Available Despite the increasing investment in sustainable development over the past decade, a systematic review of sustainable construction project financing is lacking. The objectives of this paper are to conduct a systematic review to examine the policies, practices, and research efforts in the area of sustainable construction project financing, and to explore the potential opportunities for the future research. To achieve these goals, this paper first reviewed the sustainable construction project financing practices implemented by four representative developed economies including the United Kingdom, the United States, Singapore, and Australia. Then, this paper reviewed the efforts and initiatives launched by three international organizations including the United Nations, the Organization for Economic Co-operation and Development, and International Finance Corporation. After that, this paper reviewed the research efforts of sustainable construction project financing published in peer-review journals and books. This paper identified four major research themes within this area, which are the review of financial stakeholders and market of sustainable construction, benefits and barriers to sustainable construction project financing, financial vehicles for sustainable construction projects, innovative models and mechanisms for sustainable construction project financing. Additionally, this paper revealed five directions for the future research of sustainable construction project financing, which are the identification of financial issues in sustainable construction projects, the investigation of financial vehicles for sustainable construction projects in terms of their strengths, limitations, and performances, the examination of critical drivers for implementing sustainable construction project financing, the development of a knowledge-based decision support system for implementing sustainable construction financing, and the development of best practices for

    Full Text Available Sustainable tourism has achieved the status of being the superior goal in Norwegian government tourism policy, and is attaining much attention in the international scientific and political discourse on tourism. However, have policies on sustainable tourism and related concepts actually managed to make tourism more sustainable? This article seeks to address this question by first presenting the history of sustainable tourism and related concepts, and specifically analyzing how the triple bottom line approach has influenced the prevailing understanding of the concept of sustainable tourism. The article concludes by claiming that prevailing EU as well as Norwegian national policies aiming to make tourism more sustainable most likely will result in “sustaining tourism” more than actually making tourism more sustainable. The article uses Norway—the “home of the Brundtland report”—as an illustrative case for the discussion.

    The scale of land-contamination problems, and of the responses to them, makes achieving sustainability in contaminated land remediation an important objective. The Sustainable Remediation Forum in the UK (SuRF-UK) was established in 2007 to support more sustainable remediation practice in the UK. The current international interest in 'sustainable remediation' has achieved a fairly rapid consensus on concepts, descriptions and definitions for sustainable remediation, which are now being incorporated into an ISO standard. However the sustainability assessment methods being used remain diverse with a range of (mainly) semi-quantitative and quantitative approaches and tools developed, or in development. Sustainability assessment is site specific and subjective. It depends on the inclusion of a wide range of considerations across different stakeholder perspectives. Taking a tiered approach to sustainability assessment offers important advantages, starting from a qualitative assessment and moving through to semi-quantitative and quantitative assessments on an 'as required' basis only. It is also clear that there are a number of 'easy wins' that could improve performance against sustainability criteria right across the site management process. SuRF-UK has provided a checklist of 'sustainable management practices' that describes some of these. This paper provides the rationale for, and an outline of, and recently published SuRF-UK guidance on preparing for and framing sustainability assessments; carrying out qualitative sustainability assessment; and simple good management practices to improve sustainability across contaminated land management activities.

    Driese, K. L.; Sivanpillai, R.

    2007-12-01

    Ever increasing demand for food and fiber calls for farm management strategies such as effective use of chemicals and efficient water use that will maximize productivity while reducing adverse impacts on the environment. Remotely sensed data collected by satellites are a valuable resource for farmers and ranchers for gaining insights about farm and ranch productivity. While researchers in universities and agencies have made tremendous advances, technology transfer to end-users has lagged, preventing the farmers from taking advantage of this valuable resource. To overcome this barrier, the Upper Midwest Aerospace Consortium (UMAC), a NASA funded program headed by the University of North Dakota, has been working with end-users to promote the use of remote sensing technology for sustainable agricultural practices. We will highlight the UMAC activities in Wyoming aimed at promoting this technology to sugar-beet farmers in the Big Horn Basin. To assist farmers who might not have a computer at home, we provide them to local county Cooperative Extension Offices pre-loaded with relevant imagery. Our targeted outreach activities have resulted in farmers requesting and using new and old Landsat images to identify growth anomalies and trends which have enabled them to develop management zones within their croplands.

  3. Sustainable port infrastructure, practical implementation of the green port concept

    2014-01-01

    Full Text Available The overall idea and research interest related with the development of sustainable port infrastructure evolved around the core requirements of continuous reduction of negative environmental impacts without jeopardising economic growth. The growth of trade activities and need for competitiveness on the global market are forcing ports around the world to systematically and continuously evaluate all possibilities for the optimisation and related costs reduction. On the implementation level, the greatest challenge is how to empower workers, who operate machines and work on the shop floor, to achieve enduring performance improvements. Presented research work provides a methodological approach for finding realistic solutions to the problem of the future development challenges of seaports. The case study shown in this research represents a practical application of the green port concept with the emphasis on the overall energy efficiency improvement based on testing, deployment and demonstration of energy efficient solutions. Additional emphasis was placed on the state-of-the-art technologies and developing pilot initiatives based on modern energy solutions designed to improve efficiency in fuel consumption and emissions reduction in rubber tired gantry cranes.

  6. Trophy Hunting and Sustainability: Temporal Dynamics in Trophy Quality and Harvesting Patterns of Wild Herbivores in a Tropical Semi-Arid Savanna Ecosystem.

    Directory of Open Access Journals (Sweden)

    Victor K Muposhi

    Full Text Available The selective nature of trophy hunting may cause changes in desirable phenotypic traits in harvested species. A decline in trophy size of preferred species may reduce hunting destination competitiveness thus compromising the sustainability of trophy hunting as a conservation tool. We explored the trophy quality and trends in harvesting patterns (i.e., 2004-2015 of Cape buffalo (Syncerus caffer, African elephant (Loxodonta africana, greater kudu (Tragelaphus strepsiceros and sable (Hippotragus niger in Matetsi Safari Area, northwest Zimbabwe. We used long-term data on horn and tusk size, age, quota size allocation and offtake levels of selected species. To analyse the effect of year, area and age on the trophy size, quota size and offtake levels, we used linear mixed models. One sample t-test was used to compare observed trophy size with Safari Club International (SCI minimum score. Trophy sizes for Cape buffalo and African elephant were below the SCI minimum score. Greater kudu trophy sizes were within the minimum score threshold whereas sable trophy sizes were above the SCI minimum score between 2004 and 2015. Age at harvest for Cape buffalo, kudu and sable increased whilst that of elephant remained constant between 2004 and 2015. Quota size allocated for buffalo and the corresponding offtake levels declined over time. Offtake levels of African elephant and Greater kudu declined whilst the quota size did not change between 2004 and 2015. The quota size for sable increased whilst the offtake levels fluctuated without changing for the period 2004-2015. The trophy size and harvesting patterns in these species pose a conservation and management dilemma on the sustainability of trophy hunting in this area. We recommend: (1 temporal and spatial rotational resting of hunting areas to create refuge to improve trophy quality and maintenance of genetic diversity, and (2 introduction of variable trophy fee pricing system based on trophy size.

  7. Innovation, Cooperation, and the Perceived Benefits and Costs of Sustainable Agriculture Practices

    Directory of Open Access Journals (Sweden)

    Mark Lubell

    2011-12-01

    Full Text Available A central goal of most sustainable agriculture programs is to encourage growers to adopt practices that jointly provide economic, environmental, and social benefits. Using surveys of outreach professionals and wine grape growers, we quantify the perceived costs and benefits of sustainable viticulture practices recommended by sustainability outreach and certification programs. We argue that the mix of environmental benefits, economic benefits, and economic costs determine whether or not a particular practice involves decisions about innovation or cooperation. Decision making is also affected by the overall level of knowledge regarding different practices, and we show that knowledge gaps are an increasing function of cost and a decreasing function of benefits. How different practices are related to innovation and cooperation has important implications for the design of sustainability outreach programs. Cooperation, innovation, and knowledge gaps are issues that are likely to be relevant for the resilience and sustainability of many different types of social-ecological systems.

    Dail, David Bryan [University of Maine

    2012-08-02

    This technical report covers a 3-year cooperative agreement between the University of Maine and the Northeastern Forest Experiment Station that focused on the characterization of forest stands and the assessment of forest carbon storage (see attached for detailed description of the project). The goal of this work was to compare estimates of forest C storage made via remeasurement of FIA-type plots with eddy flux measurements. In addition to relating whole ecosystem estimates of carbon storage to changes in aboveground biomass, we explored methodologies by partitioning growth estimates from periodic inventory measurements into annual estimates. In the final year, we remeasured plots that were subject to a shelterwood harvest over the winter of 2001-02 to assess the production of coarse woody debris by this harvest, to remeasure trees in a long-term stand first established by NASA, to carry out other field activities at Howland, and, to assess the importance of downed and decaying wood as well as standing dead trees to the C inputs to harvested and non harvested plots.

  13. Is Matang Mangrove Forest in Malaysia sustainably rejuvenating after more than a century of conservation and harvesting management?

    Directory of Open Access Journals (Sweden)

    Arnaud Goessens

    Full Text Available Matang Mangrove Forest Reserve (MMFR in Peninsular Malaysia is under systematic management since 1902 and still considered as the best managed mangrove forest in the world. The present study on silvimetrics assessed the ongoing MMFR forest management, which includes a first thinning after 15 years, a second thinning after 20 years and clear-felling of 30-year old forest blocks, for its efficiency and productivity in comparison to natural mangroves. The estimated tree structural parameters (e.g. density, frequency from three different-aged mangrove blocks of fifteen (MF15, twenty (MF20, and thirty (MF30 years old indicated that Bruguiera and Excoecaria spp. did not constitute a significant proportion of the vegetation (<5%, and hence the results focused majorly on Rhizophora apiculata. The density of R. apiculata at MF15, MF20 and MF30 was 4,331, 2,753 and 1,767 stems ha(-1, respectively. In relation to ongoing practices of the artificial thinnings at MMFR, the present study suggests that the first thinning could be made earlier to limit the loss of exploitable wood due to natural thinning. In fact, the initial density at MF15 was expected to drop down from 6,726 to 1,858 trees ha(-1 before the first thinning. Therefore the trees likely to qualify for natural thinning, though having a smaller stem diameter, should be exploited for domestic/commercial purposes at an earlier stage. The clear-felling block (MF30 with a maximum stem diameter of 30 cm was estimated to yield 372 t ha(-1 of the above-ground biomass and suggests that the mangrove management based on a 30-year rotation is appropriate for the MMFR. Since Matang is the only iconic site that practicing sustainable wood production, it could be an exemplary to other mangrove locations for their improved management.

    Full Text Available Presently the conducted studies on how SMEs should integrate sustainability align with their core business principle is limited. Most of the discussion on this field is emphasized to address issues for larger organizations and very limited effort on small firms. The drivers and barriers of approaching sustainability practices in SMEs are different from those in large organizations since SMEs lack technical specialist, experience and money required to make such strategy. Since SMEs play a significant role in nation’s economic growth, it is essential to study and find their drivers and barriers toward sustainability business practices constitutes main motivation of this paper. This is a primary finding that aims to understand the SME motivation and barriers that are facing in implementing green sustainable business practices to offer insight look to small firms to find key factors that influence adoption of sustainability business approach within their management practices.

    Full Text Available The construction industry with its nature of project delivery is very fragmented in terms of the various processes that encompass design, construction, facilities and assets management. Facilities managers are in the forefront of delivering sustainable assets management and hence further the venture for mitigation and adaptation to climate change. A questionnaire survey was conducted to establish perceptions, level of commitment and knowledge chasm in practising sustainable facilities management (FM. This has significant implications for sustainable design management, especially in a fragmented industry. The majority of questionnaire respondents indicated the importance of sustainability for their organization. Many of them stated that they reported on sustainability as part of their organization annual reporting with energy efficiency, recycling and waste reduction as the main concern for them. The overwhelming barrier for implementing sound, sustainable FM is the lack of consensual understanding and focus of individuals and organizations about sustainability. There is a knowledge chasm regarding practical information on delivering sustainable FM. Sustainability information asymmetry in design, construction and FM processes render any sustainable design as a sentiment and mere design aspiration. Skills and training provision, traditionally offered separately to designers and facilities managers, needs to be re-evaluated. Sustainability education and training should be developed to provide effective structures and processes to apply sustainability throughout the construction and FM industries coherently and as common practice.

    The global Climate change may affect biodiversity and the functioning of ecosystems by changing the appropriate locations for the development and establishment of the species. The Hancornia speciosa, popularly called Mangaba, is a plant species that has potential commercial value and contributes to rural economic activities in Brazil. The aim of this study was to evaluate the impact of global climate change on the potential geographic distribution, productivity, and value of production of H. speciosa in Brazil. We used MaxEnt to estimate the potential geographic distribution of the species in current and future (2050) climate scenarios. We obtained the productivity and value of production for 74 municipalities in Brazil. Moreover, to explain the variation the productivity and value of production, we constructed 15 models based on four variables: two ecological (ecological niche model and the presence of Unity of conservation) and two socio-economic (gross domestic product and human developed index). The models were selected using Akaike Information Criteria. Our results suggest that municipalities currently harvesting H. speciosa will have lower harvest rates in the future (mainly in northeastern Brazil). The best model to explain the productivity was ecological niche model; thus, municipalities with higher productivity are inserted in regions with higher environmental suitability (indicated by niche model). Thus, in the future, the municipalities harvesting H. speciosa will produce less because there will be less suitable habitat for H. speciosa, which in turn will affect the H. speciosa harvest and the local economy.

    Sustainable practices in foodservice organizations including commercial and noncommercial ones are critical to ensure the protection of the environment for the future. With the rapid growth of the foodservice industry, wiser usage of input sources such as food, utilities, and single use packaging should be reconsidered for future generations. Therefore, this study aims to investigate the customer's perceptions on sustainable practices and to identify the relationship among sustainable practices, social contribution and purchase intention. The study was conducted using content analyses by reviewing articles on sustainable food service practices published domestically and abroad. Thereafter, data were collected with a face-to-face survey using a questionnaire and analyzed with factor analyses and multiple regressions. Sustainable practices classified with factor analysis consisted of 6 dimensions of green food material procurement, sustainable food preparation, green packaging, preservation of energy, waste management, and public relations on green activity, with a total of 25 green activities in foodservice operations. Consumers were not very familiar with the green activities implemented in the foodservice unit, with the lowest awareness of "green food material procurement (2.46 out of 5 points)", and the highest awareness of "green packaging (3.74)" and "waste management (3.28). The factors influencing the perception of social contribution by foodservice organizations among 6 sustainable practice dimensions were found to be public relations on green activity (β = 0.154), waste management (β = 0.204) and sustainable food preparation (β = 0.183). Green packaging (β = 0.107) and the social contribution of the foodservice organization (β = 0.761) had strong relationships with the image of the organization. The purchase intentions of customers was affected only by the foodservice image (β = 0.775). The results of this study suggest that sustainable practices by

    Alongside the central focus on the persons requiring nursing care in professional nursing practice, the perspective of the sustainability of interventions and the use of materials (for example, nursing aids and hygiene articles) is gaining prominence in nursing decision-making processes. This contribution makes the principle of sustainability concrete and delineates its importance in the context of professional nursing practice and decision-making. It further suggests the development of an ethical policy in order to systematically ensure that sustainability has a place in ethical reflection and decision-making, and describes the elements involved. Finally, a synthesis is made between the importance of the principle of sustainability, suggested ethical policies (system of ethical reflection) as they affect nursing practice and professional reflection, decision-making, and practice.

    2017-12-01

    Full Text Available Sustainability practices in port operations are critical issue to achieve port sustainability involving economic, social and environmental issues. To assist ports to successfully implant sustainability practices into their operations, this paper conceptualized the structure of sustainability practices in international port operations, by clustering the relevant issues, empirically. Using 203 samples collected from port stakeholders in the major ports in Northeast Asia, multi-measurement items were analyzed on exploratory factor analysis in SPSS 21. Results generated a structure that consists of five sub-dimensions conceptualizing sustainability practices in the context of port operations. As operative practices to accommodate current and future demands in a port, the five-factor model clustering the relevant issues incorporate environmental technologies, process and quality improvement, monitoring and upgrading, communication and cooperation, and active participation. Providing useful insights for strategic agenda to assist ports to incorporate sustainability practices in their operations, the five-factor model offer both a descriptive and diagnostic management tool for future improvement in port operations.

  1. Do Smallholder, Mixed Crop-Livestock Livelihoods Encourage Sustainable Agricultural Practices? A Meta-Analysis

    Directory of Open Access Journals (Sweden)

    Thomas K. Rudel

    2016-02-01

    Full Text Available As calls for bolstering ecosystem services from croplands have grown more insistent during the past two decades, the search for ways to foster these agriculture-sustaining services has become more urgent. In this context we examine by means of a meta-analysis the argument, proposed by Robert McC. Netting, that small-scale, mixed crop-livestock farming, a common livelihood among poor rural peoples, leads to environmentally sustainable agricultural practices. As predicted, mixed crop-livestock farms exhibit more sustainable practices, but, contrary to predictions, a small scale of operation does not predict sustainability. Many smallholders on mixed crop-livestock farms use sustainable practices, but other smallholders practice a degrading, input-scarce agriculture. Some large farm operators use soil-conserving, minimum-tillage techniques while other large operators ignore soil-conserving techniques and practice an industrialized, high chemical input agriculture. The strength and pervasiveness of the link in the data between mixed crop-livestock farming and sustainable agricultural practices argues for agricultural policies that promote mixed crop-livestock livelihoods.

    Directory of Open Access Journals (Sweden)

    Verônica Macário de Oliveira

    2016-05-01

    Full Text Available Discussions on sustainability began recently to focus on the consumption patterns of contemporary society as a major causative factors of social and environmental problems. Thus, the aim of this paper is to discuss some opportunities that companies have to influence these changes consumption patterns towards sustainability, taking as a basis the view discussed in studies of Rindova and Ravasi (2008 who consider firms as producers of culture. To this end, we performed a theoretical essay. The results show that companies can influence the formation of specific cultures with the symbolic construction of sustainable practices, contributing to the formation of a culture of sustainable consumption. This occurs from innovation in their ways of working, considering that evoke meanings that products appear to be influenced by strategic choices of producers, such as the concepts and philosophies of design (Ravasi; Rindova, 2008, which includes the development new technologies and practices (Michaelis, 2003 based on the principles of eco-efficiency (Barber, 2008; Clark, 2008, as well as changes in values and discourses that shape the cultures of business, government, media and civil society (Michaelis, 2003, also aligned with the ethical principles and shared environmental responsibility (Tukkeret al, 2008.

    Objectives To evaluate (1) the state of the art in sustainability research and (2) the outcomes of professionals’ adherence to guideline recommendations in medical practice. Design Systematic review. Data sources Searches were conducted until August 2015 in MEDLINE, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and the Guidelines International Network (GIN) library. A snowball strategy, in which reference sections of other reviews and of included papers were searched, was used to identify additional papers. Eligibility criteria Studies needed to be focused on sustainability and on professionals’ adherence to clinical practice guidelines in medical care. Studies had to include at least 2 measurements: 1 before (PRE) or immediately after implementation (EARLY POST) and 1 measurement longer than 1 year after active implementation (LATE POST). Results The search retrieved 4219 items, of which 14 studies met the inclusion criteria, involving 18 sustainability evaluations. The mean timeframe between the end of active implementation and the sustainability evaluation was 2.6 years (minimum 1.5–maximum 7.0). The studies were heterogeneous with respect to their methodology. Sustainability was considered to be successful if performance in terms of professionals’ adherence was fully maintained in the late postimplementation phase. Long-term sustainability of professionals’ adherence was reported in 7 out of 18 evaluations, adherence was not sustained in 6 evaluations, 4 evaluations showed mixed sustainability results and in 1 evaluation it was unclear whether the professional adherence was sustained.

  9. Sustainable Entrepreneurship Orientation: A Reflection on Status-Quo Research on Factors Facilitating Responsible Managerial Practices

    Directory of Open Access Journals (Sweden)

    Sascha Kraus

    2018-02-01

    Full Text Available With the global financial system having undergone vast changes since the financial crisis of 2007, scientific research concerning the investor’s point of view on sustainable investments has drastically increased. However, there remains a lack of research focused on the entrepreneur’s angle regarding sustainable oriented investments. The aim of this paper is to contribute to the understanding of sustainable financial markets by bringing together entrepreneurial and financial research. This paper provides a structured literature review, based on which the authors identify three relevant levels that they believe have an effect on the successful implementation of managerial sustainable practices; these are the individual, the firm, and the contextual levels. The results show that on the individual level sustainable entrepreneurs tend to derive their will to act more sustainably from their personal values or traits. On the organizational level, though, it can be concluded that an small and medium sized enterprise’s internal culture and the reconfiguration of resources are critical determinants for adopting a sustainable entrepreneurial orientation. Finally, on the contextual level, researchers have focused on a better understanding of how entrepreneurs can help society and the environment through sustainable entrepreneurship, and how they can act as role models or change agents in light of the fact that the choice of investing or financing based on sustainability is still in its infancy. By providing an overview on facilitating factors for responsible managerial practices on the entrepreneur’s side, this research contributes to a better understanding for both theory and practice on how sustainable practices can be implemented and facilitated.

  10. Sustainably Harvesting a Large Carnivore? Development of Eurasian Lynx Populations in Norway During 160 Years of Shifting Policy

    2010-05-01

    The management of large carnivores in multiuse landscapes is always controversial, and managers need to balance a wide range of competing interests. Hunter harvest is often used to limit population size and distribution but is proving to be both controversialand technically challenging. Eurasian lynx ( Lynx lynx) are currently managed as a game species in Norway. We describe an adaptive management approach where quota setting is based on an annual census and chart the population development through the period 1996-2008, as management has become significantly more sophisticated and better informed by the increased availability of scientific data. During this period the population has been through a period of high quotas and population decline caused by fragmented management authority and overoptimistic estimates of lynx reproduction, followed by a period of recovery due to quota reductions. The modern management regime is placed in the context of shifting policy during the last 160 years, during which management goals have moved from extermination stimulated by bounties, through a short phase of protection, and now to quota-regulated harvest. Much management authority has also been delegated from central to local levels. We conclude that adaptive management has the potential to keep the population within some bounded limits, although there will inevitably be fluctuation.

    The concept of sustainability evolved throughout the 1970s and 1980s, but was formally described by the 27 principles of the Rio Declaration on Environment and Development in 1992. Despite the passage of nearly 20years, to date there are no uniform set of federal rules, regulations, or guidelines specifically governing the environmental aspects of sustainability practices or related requirements in the United States. In this benchmark analysis, we have collected information on the sustainability programs of the five largest US companies in each of the 26 industrial sectors [based on the Forbes Global 2000 through 2009 (n=130)]. For each company, we reviewed the most recent corporate sustainability, citizenship, or responsibility report, limiting our scope to environmental components, if available. Ten criteria were identified and analyzed, including leadership, reporting, external review, certification, and individual components of environmental sustainability programs. With respect to the prevalence of sustainability components between various business sectors, we found that the Drugs and Biotechnology (87%), Household and Personal Products (87%) and Oil and Gas Operations (87%) industries had the most comprehensive environmental sustainability programs. Using the nine components of environmental sustainability as a benchmark, we identified four key components as the characteristics of the most comprehensive environmental sustainability programs. These were (1) empowering leadership with a commitment to sustainability (80%), (2) standardized reporting (87%), (3) third-party evaluation of the sustainability programs (73%), and (4) obtaining ISO 14001 certification (73%). We found that many firms shaped their own definition of sustainability and developed their associated sustainability programs based on their sector, stakeholder interests, products or services, and business model. We noted an emerging area that we have called product sustainability - one in which

  17. Sustainable Drainage Practices in Spain, Specially Focused on Pervious Pavements

    Directory of Open Access Journals (Sweden)

    Jorge Rodriguez-Hernandez

    2013-01-01

    Full Text Available The Spanish climate is full of contrasts, with torrential rains and long droughts; under these conditions, appropriate water management is essential. In Spain, until the end of the twentieth century, water management and legislative development lagged behind other more developed countries. Nowadays, great efforts are being made to reverse this situation and improve both water management and legislation in order to control the two main problems related to stormwater management in cities: floods and diffuse pollution. In this context, Sustainable Urban Drainage Systems (SUDS were developed as the main solution to these problems. The study of these techniques started in the 1970s in the USA, but they were not studied in Spain until 1993 when the University of Cantabria and CLABSA started to look into solutions for stormwater management. After 20 years of research and application, sustainable drainage in Spain is still behind other countries in spite of the efforts to change this situation, notably by the University of Cantabria with 10 years of experience in these techniques, mainly regarding pervious pavements, where more than 13 related research projects have been carried out. The future challenges focus on the application of pervious pavements for Urban Hydrological Rehabilitation.

    2001-10-01

    The economic survival of any nation depends upon its ability to produce and manage sufficient supplies of low-cost safe energy. The world's consumption of fossil fuel resources currently increasing at 3% per annum is found to be unsustainable. Projections of this trend show that mankind will exhaust all known reserves in the second half of the coming century. Governments, industrialists, commercial organizations, public sector departments and the general public have now become aware of the urgent requirements for the efficient management of resources and energy-consuming activities. Most organizations in the materials, manufacturing and retail sectors and in the service industries have also created energy management departments, or have employed consultants, to monitor energy consumption and to reduce wastage. Conversely, any sustained attempt to reduce rates of energy consumption even by as little as 0.1% per annum ensures relatively an eternal future supply as well as reduction on environmental and ecological effect. Thus, there is no long- term solution to energy flow problem other than systematic and effective energy management and the continuous application of the techniques of energy management. Essential energy management strategies in support of a sustainable energy- economy are discussed.

    2017-10-01

    City sustainable development indicators and indices have become a hot issue in academic research and practical application, alongside the high-speed worldwide urbanization and driven by the actual managing demand. This article is aimed at a clear understanding of the progress in relevant research and practice. This is done by collecting common indicators and indices for city sustainable development and making comparison of the assessment process and contents, so as to find out main obstacles for the development of this research field and explore the direction for efforts to be made next step. The article divides these indicators and indices into two categories: ① indicators serving as single index which can provide an explicit description on the relationship between economic activities and environmental carrying capacity, but have a narrow scope of assessment and use complicated methods to collect and calculate data; ② indices based on indicator systems which can represent multiple processes, could reflect the view of strong sustainability and are easy to use, but can hardly depict the responding relationship between social, environmental and economic changes for city sustainable development or assure the scientific rigor of weight setting. Practices on indicators and indices for city sustainable development was summarized, and its problems were reviewed with China being representative of transitioning countries. According to the review, great progress has been achieved in the research and practice of indicators and indices for city sustainable development, but consistency of theories, rationality of indicators and scientific rigor of methodology are to be improved significantly.

  20. Theory and Practice in Nature Conservation - Where to Seek Sustainability?

    Science.gov (United States)

    Mirek, Zbigniew; Witkowski, Zbigniew

    2017-12-01

    Contemporary nature conservation is the subject of serious disputes, with biocentrists emphasising the superiority of the good of nature, while anthropocentrists believe that conservation space should also take account of the good of humankind. The dispute concerns two very important values perceived differently, and not resolvable within any scientifi c framework. The authors postulate a return to the Christian roots of our civilisation. It was God who gave human beings the goods He had created, expecting them to be used in line with His plan. The man who lost God's plan, destroys the life of nature as well as his own. The postulated solution is the proper shaping of conscience, to condition biodiversity conservation in line with the idea of sustainable development.

    With the development of ever-expanding synthetic methodologies, a medicinal chemist's toolkit continues to swell. However, with finite time and resources as well as a growing understanding of our field's environment impact, it is critical to refine what can be made to what should be made. This review seeks to highlight multiple cheminformatic approaches in drug discovery that can influence and triage design and execution impacting the likelihood of rapidly generating high-value molecules in a more sustainable manner. This strategy gives chemists the tools to design and refine vast libraries, stress "druglikeness", and rapidly identify SAR trends. Project success, i.e., identification of a clinical candidate, is then reached faster with fewer molecules with the farther-reaching ramification of using fewer resources and generating less waste, thereby helping "green" our field.

    Weber, N.

    2013-12-01

    Most scientific software projects are dependent on the work of many diverse people, institutions and organizations. Incentivizing these actors to cooperatively develop software that is both reliable, and sustainable is complicated by the fact that the reward structures of these various actors greatly differ: research scientists want results from a software or model run in order to publish papers, produce new data, or test a hypothesis; software engineers and research centers want compilable, well documented code that is refactorable, reusable and reproducible in future research scenarios. While much research has been done on incentives and motivations for participating in open source software projects or cyberinfrastrcture development, little work has been done on what motivates or incentivizes developers to maintain scientific software projects beyond their original application. This poster will present early results of research into the incentives and motivation for cooperative scientific software development. In particular, this work focuses on motivations for the maintenance and repair of libraries on the software platform R. Our work here uses a sample of R packages that were created by research centers, or are specific to earth, environmental and climate science applications. We first mined 'check' logs from the Comprehensive R Archive Network (CRAN) to determine the amount of time a package has existed, the number of versions it has gone through over this time, the number of releases, and finally the contact information for each official package 'maintainer'. We then sent a survey to each official maintainer, asking them questions about what role they played in developing the original package, and what their motivations were for sustaining the project over time. We will present early results from this mining and our survey of R maintainers.

    Full Text Available ABSTRACT Objectives: to verify the correlation between the characteristics of professionals and the practice of sustainable actions in the medication processes in an ICU, and to determine if interventions such as training and awareness can promote sustainable practices performed by nursing staff in the hospital. Methods: before-and-after design study using Lean Six Sigma methodology, applied in an intensive care unit. Nursing staff were observed regarding the practice of ecologically sustainable actions during medication processes (n = 324 cases for each group (pre and post-intervention through a data collection instrument. The processes analyzed involved 99 professionals in the pre-intervention phase and 97 in the post-intervention phase. Data were analyzed quantitatively and the association of variables was accomplished by means of statistical inference, according to the nature of the related variables. Results: the education level was the only characteristic that showed to be relevant to an increase in sustainable practices, with a statistically significant difference (p = 0.002. When comparing before and after the intervention, there was an increase in environmentally friendly actions with statistically significant differences (p = 0.001. Conclusions: the results suggest that institutions should encourage and invest in formal education, as well as training of health professionals to promote sustainable practices in the hospital.

    Full Text Available With growing sustainability concern in mind, firms seek to implement reverse logistic systems in their operations. However, if these practices were not properly implemented, they would be costly and even ineffective. In order to guide company efforts, the present study provide a comprehensive framework based on two dimensions. On one hand, it suits a reverse logistic management model stage-by-stage. On the other hand, the framework brings together concrete measures to optimize SC sustainability from three perspectives: operative, economical and environmental. The proposed framework thus allow to balance reverse logistic practices and SC sustainability. Furthermore, we validated it by analysing six real case in different industries. Findings highlight how reverse logistic activities may improve each SC sustainability dimension.

    The present study aimed to identify firms supplying products to our university operating room (OR) that promote sustainable manufacturing methods. Results show that 72% of our suppliers, or 152 of 211 companies, do not promote sustainability practices in a salient manner. Multi-national firms document sustainability methods significantly more than U.S. divisions of multi-nationals or U.S. firms with chi-square = 157.93 (p product selection. Lack of sustainability information among suppliers in this study suggests that hospital procurement departments likely focus solely on issues like price or quality when making purchase decisions. These results also suggest an opportunity for healthcare administrators to evaluate more fully the products involved in the healthcare supply chain; the intrinsic, intangible value added to hospital products through sustainable manufacturing is consistent with responsible patient care and has the potential to create marketing and public relations value.

    Food security in Africa is extremely susceptible to erratic rainfall patterns, with 90% of agriculture done under rainfed conditions. While climate change could lead to an increased frequency of dry-spell events and shortened growing seasons, impact studies tend to overestimate their negative impacts on crop production by ignoring the potential of adaptation strategies to mitigate those impacts. Improved soil and water management strategies such as in situ rainwater harvesting (RWH) can effectively increase the resilience of cropping systems to those factors by storing additional water in the soil profile. Here we evaluate the extent to which RWH acts to increase the flexibility in planting and harvest dates, and help stabilize crop yields under various environmental and climatic conditions. Three field sites located within probable livelihood transition zones identified by Jones and Thornton (2009) were selected for further analysis in Burkina Faso, Ethiopia, and Zambia. With the use of the Soil and Water Assessment Tool (SWAT), a watershed-scale process-based biophysical model combined with a crop model component (EPIC), the reduction in the probability of failed seasons associated with the use of RWH for three crops (sorghum, millet, and maize), as well as changes in simulated yields under current climatic conditions and for the 2050s under RCP8.5 were quantified. The climate change impacts methodology suggested in SWAT, which uses monthly historical climate statistics in a weather generator combined with a simple change in monthly means from GCM projections, was replaced by bias corrected daily time series from GCMs. In fact, the SWAT methodology assumes that the variance in rainfall remains unchanged in the future, while models predict a significant change in the frequency and intensity of rainfall events which have non-negligible impacts on hydrological and biological processes. As GCMs tend to underestimate the intensity of rainfall events and overestimate

    One of the emerging concerns in the Cordillera Administrative Region, Philippines is ochratoxin A (OTA) contamination in coffee. During 2015 to 2016, a total of 51 Arabica (Coffea arabica) coffee samples from Benguet province and 71 Robusta (Coffea canephora var. Robusta) coffee samples from the provinces of Ifugao and Kalinga were analysed for OTA contamination. The OTA-producing fungal contaminants during drying and storage of Arabica and Robusta coffee were Aspergillus niger and Aspergillus ochraceus. Ochratoxin A was more commonly detected in Robusta coffee (36.6%) than in Arabica coffee (21.6%). Among the contaminated samples, Robusta coffee cherries in the drying yard had the highest mean OTA level (120.2 μg kg -1 , n = 10) while roasted Robusta coffee beans had the lowest mean level (4.8 μg kg -1 , n = 9). The onset of contamination of Arabica coffee occurred during storage, with a mean OTA level of 46.7 μg kg -1 (n = 9). Roasted coffee had lower OTA content although five samples had levels >5.0 μg kg -1 . Pearson Chi-square analysis (χ 2 ) and Fisher's exact test revealed that several post-harvest practices involving non-removal of the husk or hull and mixing of defective coffee were significantly associated with the occurrence of OTA during drying and storage (p coffee in all stages of post-harvest and rapid reduction of moisture content particularly during drying.

  13. A modified eco-efficiency framework and methodology for advancing the state of practice of sustainability analysis as applied to green infrastructure.

    Ghimire, Santosh R; Johnston, John M

    2017-09-01

    We propose a modified eco-efficiency (EE) framework and novel sustainability analysis methodology for green infrastructure (GI) practices used in water resource management. Green infrastructure practices such as rainwater harvesting (RWH), rain gardens, porous pavements, and green roofs are emerging as viable strategies for climate change adaptation. The modified framework includes 4 economic, 11 environmental, and 3 social indicators. Using 6 indicators from the framework, at least 1 from each dimension of sustainability, we demonstrate the methodology to analyze RWH designs. We use life cycle assessment and life cycle cost assessment to calculate the sustainability indicators of 20 design configurations as Decision Management Objectives (DMOs). Five DMOs emerged as relatively more sustainable along the EE analysis Tradeoff Line, and we used Data Envelopment Analysis (DEA), a widely applied statistical approach, to quantify the modified EE measures as DMO sustainability scores. We also addressed the subjectivity and sensitivity analysis requirements of sustainability analysis, and we evaluated the performance of 10 weighting schemes that included classical DEA, equal weights, National Institute of Standards and Technology's stakeholder panel, Eco-Indicator 99, Sustainable Society Foundation's Sustainable Society Index, and 5 derived schemes. We improved upon classical DEA by applying the weighting schemes to identify sustainability scores that ranged from 0.18 to 1.0, avoiding the nonuniqueness problem and revealing the least to most sustainable DMOs. Our methodology provides a more comprehensive view of water resource management and is generally applicable to GI and industrial, environmental, and engineered systems to explore the sustainability space of alternative design configurations.

    2016-07-01

    Full Text Available Accommodation and lodging are an integral component of the tourism and hospitality industry. Given the sectors’ growing contribution to resource consumption and waste, there is a growing body of literature on the attitudes, behaviours and practices of consumers, managers, staff and owners of lodging with respect to sustainability. This paper presents the results of a systematic analysis of articles on attitudes, behaviours and practices of consumers and the provision of accommodation with respect to sustainability. The results indicate that there is a dearth of longitudinal studies on the sustainability of practices and behaviours. There are limitations in geographical coverage as well as methods, with research dominated by convenience sampling approaches. It is concluded that while there appear to be improvements in the potential sustainability of lodging with respect to technological approaches, the lack of systematic long-term studies on behavioural interventions represents a significant challenge to reducing the absolute emissions of the sector as well as reductions in energy and water use and waste production. Given the lack of longitudinal studies, it is not known whether observed behavioural changes are sustained over time.

    2016-02-01

    Unintentional perioperative hypothermia has been shown to cause serious patient complications and, thus, to increase health care costs. In 2009, an evidence-based practice improvement project produced a significant decrease in unintentional perioperative hypothermia in colorectal surgical patients through monitoring of OR ambient room temperature. Project leaders engaged all interdisciplinary stakeholders in the original project, which facilitated the sustainability of the intervention method. An important aspect of sustainability is ongoing monitoring and evaluation of a new intervention method. Therefore, continued evaluation of outcomes of the protocol developed in 2009 was scheduled at specific time points after the initial small test of change with colorectal patients. This article focuses on how attention to sustainability factors during implementation of an improvement project led to the sustainability of a protocol for monitoring OR ambient room temperature with all types of surgical patients five years after the initial project.

    2015-04-25

    To assess the long-term sustainability of continuing professional development (CPD) training in pharmacy practice and learning behaviors. This was a 3-year posttrial survey of pharmacists who had participated in an unblinded randomized controlled trial of CPD. The online survey assessed participants' perceptions of pharmacy practice, learning behaviors, and sustainability of CPD. Differences between groups on the posttrial survey responses and changes from the trial's follow-up survey to the posttrial survey responses within the intervention group were compared. Of the 91 pharmacists who completed the original trial, 72 (79%) participated in the sustainability survey. Compared to control participants, a higher percentage of intervention participants reported in the sustainability survey that they had utilized the CPD concept (45.7% vs 8.1%) and identified personal learning objectives (68.6% vs 43.2%) during the previous year. Compared to their follow-up survey responses, lower percentages of intervention participants reported identifying personal learning objectives (94.3% vs 68.6%), documenting their learning plan (82.9% vs 22.9%) and participating in learning by doing (42.9% vs 14.3%) in the sustainability survey. In the intervention group, many of the improvements to pharmacy practice items were sustained over the 3-year period but were not significantly different from the control group. Sustainability of a CPD intervention over a 3-year varied. While CPD-trained pharmacists reported utilizing CPD concepts at a higher rate than control pharmacists, their CPD learning behaviors diminished over time.

  9. Harvest Regulations and Implementation Uncertainty in Small Game Harvest Management

    Directory of Open Access Journals (Sweden)

    Pål F. Moa

    2017-09-01

    Full Text Available A main challenge in harvest management is to set policies that maximize the probability that management goals are met. While the management cycle includes multiple sources of uncertainty, only some of these has received considerable attention. Currently, there is a large gap in our knowledge about implemention of harvest regulations, and to which extent indirect control methods such as harvest regulations are actually able to regulate harvest in accordance with intended management objectives. In this perspective article, we first summarize and discuss hunting regulations currently used in management of grouse species (Tetraonidae in Europe and North America. Management models suggested for grouse are most often based on proportional harvest or threshold harvest principles. These models are all built on theoretical principles for sustainable harvesting, and provide in the end an estimate on a total allowable catch. However, implementation uncertainty is rarely examined in empirical or theoretical harvest studies, and few general findings have been reported. Nevertheless, circumstantial evidence suggest that many of the most popular regulations are acting depensatory so that harvest bag sizes is more limited in years (or areas where game density is high, contrary to general recommendations. A better understanding of the implementation uncertainty related to harvest regulations is crucial in order to establish sustainable management systems. We suggest that scenario tools like Management System Evaluation (MSE should be more frequently used to examine robustness of currently applied harvest regulations to such implementation uncertainty until more empirical evidence is available.

  10. The Influence of Perceived Corporate Sustainability Practices on Employees and Organizational Performance

    2014-01-01

    Full Text Available Most previous studies on corporate sustainability (corporate social responsibility practices tend to focus on external stakeholders and outcomes. However, the influence of CSR practices on employees remains largely unexplored. In this study, we examine the influence of CSR practices on employees’ attitudes and behaviors. We investigate the mediation effect of employees’ attitudes and behaviors on the relationship between CSR practices and organizational performance. The empirical results indicate that employees’ perceptions of CSR practices have a positive impact on their organizational commitment and organizational citizenship behavior. The organizational citizenship behavior partially mediates the relationship between CSR practices and organizational performance, whereas organizational commitment indirectly mediates the relationship only through organizational citizenship behavior. This study also raises some important implications based on the empirical results.

    This project's purpose was to promote and sustain a practice change focusing on delirium utilising the clinical nurse specialist (CNS) in a leadership role. Delirium is an altered state of consciousness accompanied by an acute change in cognition that tends to have a fluctuating course. Delirium is strongly associated with negative outcomes and is often unrecognised. A policy was implemented stating that the RNs will screen patients for delirium with the confusion assessment method (CAM). Interdisciplinary delirium education was offered prior to the practice change and repeated at 3, 6 and 12 months after implementation. The documentation, completion and CAM accuracy screening were determined by the CNS. The CAM documentation and completion audit goal was met and sustained by week 21, and screenings were accurate 83% of the time. The CNS has an opportunity to take a leadership role when instituting an innovative practice change. Successful implementation of a new practice requires that patient care units are divided into cohorts with systematic roll-out of the initiative. In addition to leadership, CNS availability on the patient care units is imperative to staff acceptance and sustainability of a practice change. © 2014 John Wiley & Sons Ltd.

    2017-06-01

    Full Text Available The paper presents the results of a participatory vision development process in the Federal State of North Rhine-Westphalia (NRW in Germany. The vision development was part of a scientific research project that accompanied the development of a sustainability strategy for NRW at state level. The Sustainability Strategy NRW was adopted in July 2016 and contains parts of the vision developed in the research project: Sentences from the narrative text vision and proposed targets and indicators that back-up the vision for a sustainable NRW in 2030 were used by the state of NRW. The vision was developed in iterative steps in three consecutive dialogue rounds with different stakeholders from science and practice. The paper presents the methodological approach and the results of the vision formulation process. The paper discusses the lessons learned from the vision development—from both practical and theoretical perspectives of transition management. The paper explores the relevance of setting ambitious targets for sustainable development as part of a state strategy by taking the proposed target of a “4 × 25% modal split” by 2030 as an example. The project demonstrated that a participatory approach for vision development is time and resource consuming, but worth the effort as it improves the quality and acceptance of a vision. Furthermore, the project demonstrated that transformative science contributes valuable inputs for sustainability transitions and for facilitating participatory vision development.

    Full Text Available This technical report records and discusses the Second Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE2. The report includes a description of the alternative, experimental submission and review process, two workshop keynote presentations, a series of lightning talks, a discussion on sustainability, and five discussions from the topic areas of exploring sustainability; software development experiences; credit & incentives; reproducibility & reuse & sharing; and code testing & code review. For each topic, the report includes a list of tangible actions that were proposed and that would lead to potential change. The workshop recognized that reliance on scientific software is pervasive in all areas of world-leading research today. The workshop participants then proceeded to explore different perspectives on the concept of sustainability. Key enablers and barriers of sustainable scientific software were identified from their experiences. In addition, recommendations with new requirements such as software credit files and software prize frameworks were outlined for improving practices in sustainable software engineering. There was also broad consensus that formal training in software development or engineering was rare among the practitioners. Significant strides need to be made in building a sense of community via training in software and technical practices, on increasing their size and scope, and on better integrating them directly into graduate education programs. Finally, journals can define and publish policies to improve reproducibility, whereas reviewers can insist that authors provide sufficient information and access to data and software to allow them reproduce the results in the paper. Hence a list of criteria is compiled for journals to provide to reviewers so as to make it easier to review software submitted for publication as a “Software Paper.” 

  16. Science education for sustainability, epistemological reflections and educational practices: from natural sciences to trans-disciplinarity

    Colucci-Gray, Laura; Perazzone, Anna; Dodman, Martin; Camino, Elena

    2013-03-01

    In this three-part article we seek to establish connections between the emerging framework of sustainability science and the methodological basis of research and practice in science education in order to bring forth knowledge and competences for sustainability. The first and second parts deal with the implications of taking a sustainability view in relation to knowledge processes. The complexity, uncertainty and urgency of global environmental problems challenge the foundations of reductionist Western science. Within such debate, the proposal of sustainability science advocates for inter-disciplinary and inter-paradigmatic collaboration and it includes the requirements of post- normal science proposing a respectful dialogue between experts and non-experts in the construction of new scientific knowledge. Such a change of epistemology is rooted into participation, deliberation and the gathering of extended-facts where cultural framings and values are the hard components in the face of soft facts. A reflection on language and communication processes is thus the focus of knowledge practices and educational approaches aimed at sustainability. Language contains the roots of conceptual thinking (including scientific knowledge) and each culture and society are defined and limited by the language that is used to describe and act upon the world. Within a scenario of sustainability, a discussion of scientific language is in order to retrace the connections between language and culture, and to promote a holistic view based on pluralism and dialogue. Drawing on the linguistic reflection, the third part gives examples of teaching and learning situations involving prospective science teachers in action-research contexts: these activities are set out to promote linguistic integration and to introduce reflexive process into science learning. Discussion will focus on the methodological features of a learning process that is akin to a communal and emancipatory research process within

    2017-03-01

    It has been argued, extensively and internationally, that sustained school-based continuous professional development (CPD) has the potential to overcome some of the shortcomings of traditional one-off CPD programs. Yet, the evidence base on more effective or less effective forms of CPD is contradictory. The mechanisms by which sustained support should be offered are unclear, and the impacts on teachers' and students' learning are complex and difficult to track. The purpose of this study was to examine the impact of a sustained school-based, tailored, and supported CPD program on teachers' practices and students' learning. Data are reported from 6 case studies of individual teachers engaged in a yearlong CPD program focused on cooperative learning. The CPD program involved participatory action research and frequent interaction/support from a boundary spanner (researcher/facilitator). Data were gathered from 29 video-recorded lessons, 108 interviews, and 35 field journal entries. (a) Individualized (external) support, (b) departmental (internal) support, and (c) sustained support impacted teachers' practices of cooperative learning. The teachers adapted their practices of cooperative learning in response to their students' learning needs. Teachers began to develop a level of pedagogical fluency, and in doing so, teachers advanced students' learning. Because this study demonstrates impact, it contributes to international literature on effective CPD. The key contribution is the detailed evidence about how and why CPD supported 6 individual teachers to learn-differently-and the complexity of the learning support required to engage in ongoing curriculum development to positively impact student learning.

    Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be taken as an example for sustainable food consumption. The consumption patterns of regular organic consumers seem to be close to the sustainable diet concept of FAO. Certain organic-related measures might therefore be useful in the sustainability assessment of diets, e.g., organic production and organic consumption. Since diets play a central role in shaping food systems and food systems shape diets, the role of organic consumption emerges as an essential topic to be addressed. This role may be based on four important organic achievements: organic agriculture and food production has a definition, well-established principles, public standards, and useful metrics. By 2015, data for organic production and consumption are recorded annually from more than 160 countries, and regulations are in force in more than 80 countries or regions. The organic food system puts the land (agri-cultura) back into the diet; it is the land from which the diet in toto is shaped. Therefore, the organic food system provides essential components of a sustainable diet.

    Jordan is one of the world's most water-deficit countries with only about 4% of the total land area considered arable. As a consequence agricultural production is greatly constrained by limited natural resources. Therefore, a major challenge for the country is to promote the sustainable use of natural resources for agricultural purposes. This challenge is being made harder by the ongoing processes of degradation due to increased population pressure, which undermine any social and economic development gains. In the southern plains of Jordan, sustainability of farming practices has worsened in the past three decades, exacerbating pressure on land and increasing land degradation processes. Non-sustainable land use practices include improper ploughing, inappropriate rotations, inadequate or inexistent management of plant residues, overgrazing of natural vegetation, random urbanization, land fragmentation and over-pumping of groundwater. The root cause is the high population growth which exerts excessive pressure on the natural resources to meet increased food and income demand. The poorest farmers who are increasingly growing cereals on marginal areas. Wheat and barley are now grown with little to no rotation, with no nutrient replenishment, and at places avoiding even fallow. Small landholding sizes and topographic features of the area tend to oblige longitudinal mechanized tillage operations along the slopes. Overall, the constraints facing the deprived land users such as, poor access to technology, capital and organization are the factors that lead into unsustainable practices. The main bottlenecks and barriers that hinder mainstreaming of sustainable land management in Jordan can be grouped into three main categories: (i) Knowledge, (ii) Institutional and Governance, and (iii) Economic and Financial. In this case study, the key challenge was to create a knowledge base among local stakeholders - including planners, extension officers, NGO/community leaders, teachers

    Evidence that the learning gains of preschool fade as children transition into elementary school has led to increased efforts to sustain preschool advantages during this key transitional period. This study explores whether the observed benefits of sustainability practices for a range of child outcomes are explained and/or moderated by family and school mechanisms selecting children into experiencing these practices. Analyses of the Early Childhood Longitudinal Study-Birth Cohort revealed that both family and school factors predicted children’s exposure to several PK-3 sustainability practices. PK-3 sustainability practices were associated with reading (but not math) gains and better interpersonal skills (but not fewer externalizing behaviors) following the transition into kindergarten. These links were not conditioned by the selection mechanisms. The findings highlight who is more likely to seek out (at the family level) or offer (at the school level) sustainability practices and how relevant they are to fighting preschool fadeout.

    Full Text Available Many managers and researchers alike are asking: What does an enterprise need to do to generate a proper balance between economic, social, and ecological objectives while gaining superior corporate financial performance, resilience, and sustainability? Several leadership concepts for enhancing organizational sustainability have emerged in recent years, but none provides an integrative approach, with the exception of Sustainable Leadership (SL. However, empirical research examining the effects of various SL practices on financial performance and other business outcomes is lacking. This article addresses this gap by empirically investigating the relationships between 23 SL practices and financial performance. Using a cross-sectional survey, data stem from 439 managers in small and medium-sized enterprises (SMEs in Thailand. Of the 23 SL practices in SL, 16 were significantly associated with corporate financial performance. Four SL practices, in particular—amicable labor relations, valuing employees, social responsibility, plus strong and shared vision—were significant drivers, and positive predictors, of enhanced long-term firm performance. Lastly, implications, limitations, and future directions are discussed.

    Purpose: The purpose of this study was to investigate key factors associated with the economic sustainability of the Registered Dental Hygienist in Alternative Practice (RDHAP).Methods: An invitation to participate in a 38-question electronic survey was sent via postal mail to 440 RDHAP licentiate addressees obtained through the Dental Hygiene Committee of California (DHCC). Legal restrictions did not allow for obtaining the RDHAP licentiate email addresses from the DHCC. The survey was disseminated via email to the 254 RDHAPs who were members of the California Dental Hygienists' Association. Additional invitations to participate were made via flyer distribution at an RDHAP symposium, and on RDHAP only social media sites.Results: The response rate was an estimated 16%. While 44% of the RDHAPs reported some employment in a traditional dental practice, given the opportunity, 61% of these respondents indicated that they would practice exclusively as an RDHAP. With regard to practice strategic planning and alliances, 31% felt that dentists lacked knowledge of the RDHAP, and 25% indicated dentists were resistant to this workforce model. Regarding RDHAP practice staffing patterns, 75% indicated not having any employees. When asked about business systems, 64% had solo, portable practices and 16% had standalone practices. Economic sustainability challenges included practice business/equipment expenses (29%), insurance/reimbursement issues (21%), patient flow (19%) and RDHAP visibility (14%).Conclusions: RDHAP practices face challenges including the need for strategic planning and intra- and inter-professional alliances, efficient and effective patient flow, optimal staffing patterns and effective business systems. Focus on enhancing RDHAP visibility within the dental and medical communities should be a priority. In addition, further research should explore RDHAPs aligning with community-based clinics, Federally Qualified Health Centers and Dental Support Organizations

    In a pay-for-performance environment, implementing and sustaining evidence-based practice (EBP) is no longer a luxury but a necessity. A critical driving force for EBP is that our communities-the people we serve-expect to receive care based on the best available evidence. Transformational nursing leadership is required to create an infrastructure that influences organizational factors, processes and expectations, thus enabling the sustainability of EBP. The American Nurses Credentialing Center and the American Organization of Nurse Executives provide a framework for nursing leaders to consider when designing EBP implementation structures. This exemplar illustrates nursing leadership competencies with regard to implementation and sustainability of EBP within a multihospital system.

    Environmental concerns have given rise to eco-label initiatives in the seafood industry and a shift to more sustainable fishing practices in the U.S. Currently, the greenhouse gas emissions of fisheries are being considered in the sustainability criteria of the consumer advocacy group Seafood Watch. We looked at sustainable practices employed by U.S. tuna fisheries and find the term "sustainably sourced" changes when climate forcing is added to the criteria. Specifically, there are three sustainable practices at odds with climate change mitigation: 1) the use of selective fishing gear reduces bycatch but increases fuel use; 2) fishing within exclusive economic zones is more equitable to coastal fishermen, and allows the high seas to serve as an ecological bank, but fishing within these regions means fisheries are subject to more stringent fuel sulfur laws thereby diminishing the cooling effects of sulfate aerosols and increasing climate forcing; and 3) removing sulfur from fuels improves air quality but there are added emissions from the refinery process. We used ship registry data, historical sulfur levels in fuels, gear-specific fishery fuel use data collected from the literature, historical gear-specific tuna landings data, and a range of global warming potentials to estimate the climate forcing of U.S. tuna fisheries over the last fifteen years. We found that for tuna caught within exclusive economic zones, the net fuel-related climate forcing has more than doubled over the last fifteen years. We also normalized the fuel-related climate forcing results to a unit of tuna protein and compared these results to other farmed sources of protein. We found that tuna caught within exclusive economic zones has the highest climate impact of all land-based protein sources considered, with the exception of beef. Our results can inform policy makers and consumer advocacy groups which is an important step in communicating the climate impact of dietary choices to consumers.

    Surgical site infections (SSI) increase morbidity and mortality, hospital costs, length of stay, readmissions, and risk of litigation and may impact a facility's reputation. Through implementation of a Six Sigma, interdisciplinary team process and the Contextual Model for change engaged all stakeholders. A total of 44 perioperative processes were evaluated, with 15 processes ultimately altered. Revisions involved identifying inconsistent implementation of procedures and standardizing processes, as well as utilizing new suture techniques and products including disposable electrocardiogram leads and pacing wires, antibiotic-coated sutures, and silver-impregnated midsternal dressings. In isolated coronary artery bypass grafting with donor-site procedures, an incidence of 3.74 per 100 procedures was reduced to 0.7 and ultimately to 0. No patients who underwent coronary artery bypass grafting developed a deep sternal wound infection in over 30 months and 590 procedures, resulting in an estimated cost savings of more than $600 000, from May 2012 through December 2014. A significant reduction in deep sternal wound infections was achieved by working at all levels of the organization through a multidisciplinary approach to create sustained change. Using real-time observations for current practices, areas for improvement were identified. By engaging frontline staff in the process, ownership of the outcomes and adherence to practice change were promoted. The result was a dramatic, rapid, and sustainable improvement in the prevention of deep sternal wound infection.

    Full Text Available Over the past years, the issue of sustainable entrepreneurship has coagulated multiple research interests due to the fact that it integrates three main pillars, namely human resource management (people and the concerns for planet protection and for the economic effectiveness sustained by profit. The rapid social and economic transformations have imposed the assumption of an integrative perspective, especially to the organizations oriented to ensure their viability on the market and industry. Hereby, researchers believe that such an approach should be indicative of start-ups which should advance feasible solutions to market imperfections through innovative products and services and through effective marketing models. Against this backdrop, the present paper aims to investigate the correlations between sustainable entrepreneurship and the marketing types articulated by the Contemporary Marketing Practices (CMP research program, relying on a questionnaire-based survey conducted with 104 start-up entrepreneurs in Romania. As the findings show, the discussed marketing types often discretionary correlate in practice with the most important dimension of sustainability that is people.

    2011-03-01

    Communication plays an important role in all aspects of the development and use of policy. We present a communication-centered perspective on the processes of enacting public health policies. Our proposed conceptual framework comprises 4 communication frames: orientation, amplification, implementation, and integration. Empirical examples from 2 longitudinal studies of school-based health policies show how each frame includes different communication processes that enable sustainable public health policy practices in school-based health initiatives. These 4 frames provide unique insight into the capacity of school-based public health policy to engage youths, parents, and a broader community of stakeholders. Communication is often included as an element of health policy; however, our framework demonstrates the importance of communication as a pivotal resource in sustaining changes in public health practices.

    Full Text Available This report records and discusses the Third Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE3. The report includes a description of the keynote presentation of the workshop, which served as an overview of sustainable scientific software. It also summarizes a set of lightning talks in which speakers highlighted to-the-point lessons and challenges pertaining to sustaining scientific software. The final and main contribution of the report is a summary of the discussions, future steps, and future organization for a set of self-organized working groups on topics including developing pathways to funding scientific software; constructing useful common metrics for crediting software stakeholders; identifying principles for sustainable software engineering design; reaching out to research software organizations around the world; and building communities for software sustainability. For each group, we include a point of contact and a landing page that can be used by those who want to join that group’s future activities. The main challenge left by the workshop is to see if the groups will execute these activities that they have scheduled, and how the WSSSPE community can encourage this to happen.

  11. How the organic food system supports sustainable diets and translates these into practice

    2015-06-01

    Full Text Available Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be taken as an example for sustainable food consumption. The consumption patterns of regular organic consumers seem to be close to the sustainable diet concept of FAO. Certain organic-related measures might therefore be useful in the sustainability assessment of diets, e.g. organic production and organic consumption. Since diets play a central role in shaping food systems and food systems shape diets, the role of organic consumption emerges as an essential topic to be addressed. This role may be based on four important organic achievements: organic agriculture and food production has a definition, well-established principles, public standards and useful metrics. By 2015 data for organic production and consumption is recorded annually from more than 160 countries, and regulations are in force in more than 80 countries or regions. The organic fo

    There is strong interest in implementation science to address the gap between research and practice in public health. Research on the sustainability of evidence-based interventions has been growing rapidly. Sustainability has been defined as the continued use of program components at sufficient intensity for the sustained achievement of desirable program goals and population outcomes. This understudied area has been identified as one of the most significant translational research problems. Adding to this challenge is uncertainty regarding the extent to which intervention adaptation and evolution are necessary to address the needs of populations that differ from those in which interventions were originally tested or implemented. This review critically examines and discusses conceptual and methodological issues in studying sustainability, summarizes the multilevel factors that have been found to influence the sustainability of interventions in a range of public health and health care settings, and highlights key areas for future research. Expected final online publication date for the Annual Review of Public Health Volume 39 is April 1, 2018. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

    Improving health care quality requires effective and timely spread of innovations that support evidence-based practices. However, there is limited rigorous research on the process of spread, factors influencing spread, and models of spread. It is particularly important to study spread within the home care sector given the aging of the population, expansion of home care services internationally, the high proportion of older adult users of home care services, and the vulnerability of this group who are frail and live with multiple chronic conditions. The purpose of this study was to understand how best practices related to older adults are spread within home care organizations. Four home care organizations in Ontario, Canada that had implemented best practices related to older adults (falls prevention, pain management, management of venous leg ulcers) participated. Using a qualitative grounded theory design, interviews were conducted with frontline providers, managers, and directors at baseline (n = 44) and 1 year later (n = 40). Open, axial, and selective coding and constant comparison analysis were used. A model of the process of spread of best practices within home care organizations was developed. The phases of spread included (1) committing to change, (2) implementing on a small scale, (3) adapting locally, (4) spreading internally to multiple users and sites, and (5) disseminating externally. Factors that facilitated progression through these phases were (1) leading with passion and commitment, (2) sustaining strategies, and (3) seeing the benefits. Project leads, champions, managers, and steering committees played vital roles in leading the spread process. Strategies such as educating/coaching and evaluating and feedback were key to sustaining the change. Spread occurred within the home care context of high staff and manager turnover and time and resource constraints. Spread of best practices is optimized through the application of the phases of spread

    Directory of Open Access Journals (Sweden)

    Ana Silvia Rocha Ipiranga

    2014-04-01

    Full Text Available Knowledge and knowing processes as work and life practices are not univocal. They are not related to knowledge as an autonomous body of propositions, but permeated with new identities and action modes, which are continuously formed, promoting learning opportunities. The objective of this research is formulated in the understanding of this shift between knowing and knowledge when describing practical learning in everyday work life, reflecting on the implications of this social labor process on small business network sustainability. A qualitative case study approach was used. In line with the theoretical and epistemological choices that guided this research, we decided to use an analysis of discursive practices approach and, accordingly, data collection was based on triangulation techniques in favor of interpretation enrichment. The knowledge to act, revealed in the analysis, suggested that organizations are social worlds forming a standard that holds life, work and organizational practices together. They negotiate, circulate, transform and reproduce, forming a network of actors and favoring sustainable practices learning.

    2007-01-01

    This paper describes an education program designed to improve palliative care practice through the development of workplace hospice palliative care resources (PCRs), and its impact on knowledge transfer and longer-term changes to clinical practice. Evaluation methods included pre- and post-program questionnaires, and a survey of learners' (n=301) perceptions of program learning strategies. Interviews (n=21) were conducted with a purposeful sample of PCRs and representatives from their work sites. Ratings of the sessions indicated that they were relevant to learners' clinical practice. At follow up, the majority of learners (83%) continued to serve as PCRs. Many positive effects were identified, including enhanced pain and symptom management, staff education, and development of care policies and guidelines. Management support, particularly the prioritization of palliative care and staff development, were factors facilitating sustained implementation. These findings highlight the importance of multimodal learning strategies and supportive work environments in the development of PCRs to enhance palliative care practice.

    Full Text Available Abstract Background New methods for prevention and health promotion and are constantly evolving; however, positive outcomes will only emerge if these methods are fully adopted and sustainable in practice. To date, limited attention has been given to sustainability of health promotion efforts. This study aimed to explore facilitators, barriers, and requirements for sustainability as experienced by professionals two years after finalizing the development and implementation of a multisectoral child health promotion programme in Sweden (the Salut programme. Initiated in 2005, the programme uses a 'Salutogenesis' approach to support health-promoting activities in health care, social services, and schools. Methods All professionals involved in the Salut Programme's pilot areas were interviewed between May and September 2009, approximately two years after the intervention package was established and implemented. Participants (n = 23 were midwives, child health nurses, dental hygienists/dental nurses, and pre-school teachers. Transcribed data underwent qualitative content analysis to illuminate perceived facilitators, barriers, and requirements for programme sustainability. Results The programme was described as sustainable at most sites, except in child health care. The perception of facilitators, barriers, and requirements were largely shared across sectors. Facilitators included being actively involved in intervention development and small-scale testing, personal values corresponding to programme intentions, regular meetings, working close with collaborators, using manuals and a clear programme branding. Existing or potential barriers included insufficient managerial involvement and support and perceived constraints regarding time and resources. In dental health care, barriers also included conflicting incentives for performance. Many facilitators and barriers identified by participants also reflected their perceptions of more general and forthcoming

    2011-07-19

    This document offers a menu of 18 different, yet complimentary preferred practices and policies. The best practices cover all phases of the wind energy development process - from the policies that allow for wind development, to the sustainable operation of a wind project, to the best practices for decommissioning a spent turbine - including applications for offshore wind. The practices include those that have been previously tested and proven effective, as well as new practices that were identified by experts in the field as needed for future wind developments. Each best practice includes information about the opportunities and challenges (pros and cons), and offers a case example that illustrates how that best practice is being utilized by a particular jurisdiction or wind project. The practices described in this publication were selected by a diverse group of interests from the Great Lakes Wind Collaborative that included environmental groups, industry, and federal, state and local government regulators. They were identified through a year long process that included a literature review, online survey and interviews with individuals from the public, private and non-profit sectors.

    2016-05-01

    Full Text Available An eco-village as defined by Robert Gilman is a “human-scale, full-featured settlement where you feel you know the others, and human activities are integrated with natural, biological systems.” Roland Mayerl argued that this maybe ideal, but there are huge challenges. He claims the challenges are at different levels—there is the physical layer that constitutes food production, animals, water and wastewater treatment. Other layers will be the built environment, the economic system and the governance in the village.This paper argues that one of the challenging layers is the human layer that was excluded in the modeling of many eco-village works. While there are many good models of an eco-village, sustainability will primarily be laid on the shoulders of the members of the community or the village for that matter. Sustainability should be espoused by the members of the eco-village. But how can sustainability be attained? What sustainability approach or strategy can be employed?“Communities of practice (COP are formed by people who engage in a process of collective learning in a shared domain of human endeavor.“ (Wenger, 2004 COPs are concepts commonly applied in organizations and virtual communities. Using this approach together with periphery participation and situated learning, this paper presents a human-based model of a sustainable eco-village and some useful examples.The paper also argues that an eco-village necessitates the support of technology in enhancing and preserving the shared practices. Hence, use of social media deployed in the web is one of the recommended ways that also permit collective action among members of the eco-village.

  2. Documenting Elementary Teachers' Sustainability of Instructional Practices: A Mixed Method Case Study

    Cotner, Bridget A.

    School reform programs focus on making educational changes; however, research on interventions past the funded implementation phase to determine what was sustained is rarely done (Beery, Senter, Cheadle, Greenwald, Pearson, et al., 2005). This study adds to the research on sustainability by determining what instructional practices, if any, of the Teaching SMARTRTM professional development program that was implemented from 2005--2008 in elementary schools with teachers in grades third through eighth were continued, discontinued, or adapted five years post-implementation (in 2013). Specifically, this study sought to answer the following questions: What do teachers who participated in Teaching SMARTRTM and district administrators share about the sustainability of Teaching SMARTRTM practices in 2013? What teaching strategies do teachers who participated in the program (2005--2008) use in their science classrooms five years postimplementation (2013)? What perceptions about the roles of females in science, technology, engineering, and mathematics (STEM) do teachers who participated in the program (2005--2008) have five years later (2013)? And, What classroom management techniques do the teachers who participated in the program (2005--2008) use five years post implementation (2013)? A mixed method approach was used to answer these questions. Quantitative teacher survey data from 23 teachers who participated in 2008 and 2013 were analyzed in SAS v. 9.3. Descriptive statistics were reported and paired t-tests were conducted to determine mean differences by survey factors identified from an exploratory factor analysis, principal axis factoring, and parallel analysis conducted with teacher survey baseline data (2005). Individual teacher change scores (2008 and 2013) for identified factors were computed using the Reliable Change Index statistic. Qualitative data consisted of interviews with two district administrators and three teachers who responded to the survey in both

    First order streams in the Van Duzen River and lower Eel River watersheds owned by Pacific Lumber Company (Palco) in Humboldt County, California, were surveyed and small sedimentation basins were installed to develop quantitative estimates of sediment yield. A random study design was developed to investigate the potential effects of different geologic substrates and forest management on sediment yield. The drainage area for these streams was about 5 to 10 ha where fluvial characteristics were expressed. The erosion processes within the scope of this investigation included surface erosion from hillslopes and harvest units, rill and gully erosion that may occur in relation to skid trails (recently used or abandoned), and stream channel erosion, including bank erosion and small-scale mass wasting. Temporary sedimentation basins were installed in 30 randomly chosen channels to quantify relative amounts of sediment yield from watersheds with different management conditions (treatment sites) and second-growth stands not recently entered (control sites). Most treatment sites were clearcut harvests. Two classes of treated sites were sampled: sites harvested under stricter regulations of a Habitat Conservation Plan (HCP) and sites harvested prior to implementation of the HCP. Channel surveys were also conducted to characterize conditions and identify existing evidence of channel erosion and surface erosion in areas adjacent to the channel. Results from winter 2001/02 suggested that there may be differences in sediment yield among geologic substrates, with the Wildcat having relatively low sediment yield values. Treatment effects were significantly different (ANOVA, p effect on sediment yield may be influenced by the fact that the HCP treatment sites have experienced only one or two post-harvest winters, while the pre-HCP treatment sites experienced relatively severe winters over a longer post-harvest period. In addition, the fact that the control sites tended to have higher

    Malaysia is facing an increasing trend in industrial solid waste generation due to industrial development.Thus there is a paramount need in taking a serious action to move toward sustainable industrial waste management. The main aim of this study is to assess practicing solid waste minimization by manufacturing firms in Shah Alam industrial state, Malaysia. This paper presents a series of descriptive and inferential statistical analysis regarding the level and effects of practicing waste minimization methods, and seriousness of barriers preventing industries from practicing waste minimization methods. For this purpose the survey questions were designed such that both quantitative (questionnaire) and qualitative (semi-structures interview) data were collected concurrently. Analysis showed that, the majority of firms (92%) dispose their wastes rather than practice other sustainable waste management options. Also waste minimization methods such as segregation of wastes, on-site recycle and reuse, improve housekeeping and equipment modification were found to have significant contribution in waste reduction (pstrengths, weaknesses, threats and opportunities. Accordingly, ten policies were recommended for improvement of practicing waste minimization by manufacturing firms as the main aim of this research. Implications This manuscript critically analysis waste minimization practices by manufacturing firms in Malaysia. Both qualitative and quantitative data collection and analysis were conducted to formulate SWOT and TOWS matrix in order to recommend policies and strategies for improvement of solid waste minimization by manufacturing industries.

    Full Text Available Background/Aim. Internationally, mental health policy requires clinicians to shift from a medical to a recovery-oriented approach. However, there is a significant lag in the translation of policy into practice. Occupational therapists have been identified as ideally situated to be recovery-oriented yet limited research exploring how they do this exists. This study aimed to explore Australian occupational therapists’ experiences of developing and sustaining recovery-orientation in mental health practice. Methods. Semistructured, in-depth interviews were conducted with twelve occupational therapists working across different mental health service types. Participants identified themselves as being recovery-oriented. Data were analysed using constant comparative analysis. Results. Occupational therapists described recovery-oriented practice as an active, ongoing, and intentional process of seeking out knowledge, finding fit between understandings of recovery-oriented practice and their professional identity, holding hope, and developing confidence through clinical reasoning. Human and systemic aspects of therapists’ workplace environment influenced this process. Conclusions. Being a recovery-oriented occupational therapist requires more than merely accepting a specific framework. It requires commitment and ongoing work to develop and sustain recovery-orientation. Occupational therapists are called to extend current leadership activity beyond their workplace and to advocate for broader systemic change.

    This paper evaluates current stakeholder involvement (SI) practices in science through a web-based survey among scholars and researchers engaged in sustainability or transition research. It substantiates previous conceptual work with evidence from practice by building on four ideal types of SI in science. The results give an interesting overview of the varied landscape of SI in sustainability science, ranging from the kinds of topics scientists work on with stakeholders, over scientific trade-offs that arise in the field, to improvements scientists wish for. Furthermore, the authors describe a discrepancy between scientists' ideals and practices when working with stakeholders. On the conceptual level, the data reflect that the democratic type of SI is the predominant one concerning questions on the understanding of science, the main goal, the stage of involvement in the research process, and the science-policy interface. The fact that respondents expressed agreement to several types shows they are guided by multiple and partly conflicting ideals when working with stakeholders. We thus conclude that more conceptual exchange between practitioners, as well as more qualitative research on the concepts behind practices, is needed to better understand the stakeholder-scientist nexus.

    Full Text Available Dhaka, the capital of Bangladesh is one of the most populated megacity in the world and the population growth in this city is extremely high. To support growing food demand of increasing population, food supply should be secure and sustainable. On the other hand, with the pace of urbanization built-up areas are increasing; hence supply of roof space is also increasing. Rooftop farming can provide solution to increased food demand and also can promote a sustainable and livable city. Local fresh and safe food can be ensured through roof gardens in Dhaka city. The aim of the study is to explore the present practice and challenges of rooftop farming that was encountered by practitioners. Mirpur and Mohammadpur areas have been selected as study areas. Two practitioners are interviewed and 60 non-practitioners are surveyed. Results show that rooftop farming can support environment by improving air quality, reducing carbon in the atmosphere and can benefit society by reducing storm water management cost. One of the significant findings from the non-practitioner survey is that maximum people are willing to practice rooftop farming and want to provide at least 50% of roof space for rooftop farming. Finally some recommendations have been suggested to improve rooftop farming practice and encourage more people to practice rooftop farming in future.

  9. The Impact of Assumed Uncertainty on Long-Term Decisions in Forest Spatial Harvest Scheduling as a Part of Sustainable Development

    Full Text Available The paper shows how the aspects of uncertainty in spatial harvest scheduling can be embedded into a harvest optimization model. We introduce an approach based on robust optimization that secures better scheduling schematics of the decision maker while eliminating a significant portion of uncertainty in the decisions. The robust programming approach presented in this paper was applied in a real management area of Central Europe. The basic harvest scheduling model with harvest-flow constraints was created. The uncertainty that is assessed here is due to forest inventory errors and growth prediction errors of stand volume. The modelled results were compared with randomly simulated errors of stand volume. The effects of different levels of robustness and uncertainty on harvest-flow were analyzed. The analysis confirmed that using the robust approach for harvest decisions always ensures significantly better solutions in terms of the harvested volume than the worst-case scenarios created under the same constraints. The construction of a mathematical model as well as the methodology of simulations are described in detail. The observed results confirmed obvious advantages of robust optimization. However, many problems with its application in forest management must still be solved. This study helps to address the need to develop and explore methods for decision-making under different kinds of uncertainty in forest management.

The concept of Circular Economy has started to develop in response to the crisis of the traditional model and the need to deal with limited resources. A key role in the pursuit and implementation of circular economy is taken by investments in innovation and technologies that enhance the scraps of industrial and / or agricultural sectors. This can lead not only to a reduction of waste and hence environmental impacts but also in net savings for businesses of up to 604 billion Euros throughout the European Union, in line with the global framework (Sustainable Development Goals 2015 -2030. The paper try to demonstrate through an inductive model, several tables, figures and our analysis that the success of the Strategy of Sustainable Development depend, in the next years, by the application of the best practices of the Circular Economy.

    Sachdev, Gloria

    2014-08-15

    This article discusses considerations for making ambulatory care pharmacist services at least cost neutral and, ideally, generate a margin that allows for service expansion. The four pillars of business sustainability are leadership, staffing, information technology, and compensation. A key facet of leadership in ambulatory care pharmacy practice is creating and expressing a clear vision for pharmacists' services. Staffing considerations include establishing training needs, maximizing efficiencies, and minimizing costs. Information technology is essential for efficiency in patient care delivery and outcomes assessment. The three domains of compensation are cost savings, pay for performance, and revenue generation. The following eight steps for designing and implementing an ambulatory care pharmacist service are discussed: (1) prepare a needs assessment, (2) analyze existing strengths, weaknesses, opportunities, and threats, (3) analyze service gaps and feasibility, (4) consider financial opportunities, (5) consider stakeholders' interests, (6) develop a business plan, (7) implement the service, and (8) measure outcomes. Potential future changes in national healthcare policy (such as pharmacist provider status and expanded pay for performance) could enhance the opportunities for sustainable ambulatory care pharmacy practice. The key challenges facing ambulatory care pharmacists are developing sustainable business models, determining which services yield a positive return on investment, and demanding payment for value-added services.

    Managing land sustainably is a huge challenge, especially under harsh climatic conditions such as those found in drylands. The socio-economic situation can also pose challenges, as dryland regions are often characterized by remoteness, marginality, low-productive farming, weak institutions, and even conflict. With threats from climate change, disputes over water, competing claims on land, and migration increasing worldwide, the demands for sustainable land management (SLM) measures will only increase in the future. Within the EU-funded DESIRE project, researchers and stakeholders jointly identified existing SLM technologies and approaches in 17 dryland study sites located in the Mediterranean and around the world. In order to evaluate and share this valuable SLM experience, local researchers documented the SLM technologies and approaches in collaboration with land users, utilizing the internationally recognized WOCAT questionnaires. This article provides an analysis of 30 technologies and 8 approaches, enabling an initial evaluation of how SLM addresses prevalent dryland threats, such as water scarcity, soil degradation, vegetation degradation and low production, climate change, resource use conflicts, and migration. Among the impacts attributed to the documented technologies, those mentioned most were diversified and enhanced production and better management of water and soil degradation, whether through water harvesting, improving soil moisture, or reducing runoff. Favorable local-scale cost-benefit relationships were mainly found when considered over the long term. Nevertheless, SLM was found to improve people's livelihoods and prevent further outmigration. More field research is needed to reinforce expert assessments of SLM impacts and provide the necessary evidence-based rationale for investing in SLM.

    Full Text Available Knowledge based economy, found in more than one fields, started – considering agriculture – from a transition premise towards sustainable agro-food systems. The conceptual boundaries between the two major paradigms on sustainable development of agriculture, namely the agro-industrial paradigm and the integrated territorial paradigm, is used nowadays for teaching and research purpose, as a comparison basis with an ideal case, mostly because we only have hybrid models which tend to coexist, always improving the food and goods production, also promoting innovative agro-food systems. This paper highlights the idea that the establishment of an institutional and legal framework, will have a catalytic role acting as an engine of economic growth and boosting the development of agricultural systems by mobilizing entrepreneurs in agriculture and related areas. In this regard, we present best practices of economic actors engaged in meta network of agriculture clusters.

  19. TEACHERS AS AGENTS OF SUSTAINABLE PEACE, SOCIAL COHESION AND DEVELOPMENT: THEORY, PRACTICE & EVIDENCE

    Directory of Open Access Journals (Sweden)

    Mario Novelli

    2016-12-01

    Full Text Available This paper presents a ‘peace with social justice’ framework for analysing the role of teachers as agents of sustainable peace, social cohesion and development and applies this to research evidence from Pakistan, Uganda, Myanmar and South Africa. The paper draws on evidence from a recently completed UNICEF and ESRC funded project on education and peacebuilding, and specifically from data gathered around the role of teachers. Drawing on rich fieldwork data collected between 2014‒2016 in each of the four countries, the paper will evidence the complex and contradictory role that teachers play in sustainable peace and development and its implications for teacher governance, teacher policy and teacher practice. The paper challenges the overly human capital driven logics of much teacher policy reform agendas and highlights the need and importance for a more holistic approach to teacher governance and management that recognises teachers’ multiple potential to contribute to both societal peace and development.

    At present, environmental issues become real critical barriers for many supply chain corporations concerning the sustainability of their businesses. In this context, several studies have been proposed from both academia and industry trying to develop new measurements related to green supply chain management (GSCM) practices to overcome these barriers, which will help create new environmental strategies, implementing those practices in their manufacturing processes. The objective of this study is to present the technical and analytical contribution that multi-criteria decision making analysis (MCDA) can bring to environmental decision making problems, and especially to GSCM field. For this reason, a multi-criteria decision-making methodology, combining fuzzy analytical hierarchy process and fuzzy technique for order preference by similarity to ideal solution (fuzzy TOPSIS), is proposed to contribute to a better understanding of new sustainable strategies through the identification and evaluation of the most appropriate GSCM practices to be adopted by industrial organizations. The fuzzy AHP process is used to construct hierarchies of the influential criteria, and then identify the importance weights of the selected criteria, while the fuzzy TOPSIS process employs these weighted criteria as inputs to evaluate and measure the performance of each alternative. To illustrate the effectiveness and performance of our MCDA approach, we have applied it to a chemical industry corporation located in Safi, Morocco.

    In order to support agribusiness and to attain food security for ever-increasing populations, most countries in the world have embraced modern agricultural technologies. Ecological consequences of the technocentric approaches, and their sustainability and impacts on human health have, however, not received adequate attention particularly in developing countries. India is one country that has undergone a rapid transformation in the field of agriculture by adopting strategies of the Green Revolution. This article provides a comparative analysis of the effects of older and newer paradigms of agricultural practices on ecosystem and human health within the larger context of sustainability. The study was conducted in three closely situated areas where different agricultural practices were followed: (a) the head-end of a modern canal-irrigated area, (b) an adjacent dryland, and (c) an area (the ancient area) that has been provided with irrigation for some 800 years. Data were collected by in-depth interviews of individual farmers, focus-group discussions, participatory observations, and from secondary sources. The dryland, receiving limited rainfall, continues to practice diverse cropping centered to a large extent on traditional coarse cereals and uses only small amounts of chemical inputs. On the other hand, modern agriculture in the head-end emphasizes continuous cropping of rice supported by extensive and indiscriminate use of agrochemicals. Market forces have, to a significant degree, influenced the ancient area to abandon much of its early practices of organic farming and to take up aspects of modern agricultural practice. Rice cultivation in the irrigated parts has changed the local landscape and vegetation and has augmented the mosquito population, which is a potential vector for malaria, Japanese encephalitis and other diseases. Nevertheless, despite these problems, perceptions of adverse environmental effects are lowest in the heavily irrigated area.

    Full Text Available Strategic environmental assessment (SEA is now a requirement for virtually all new Scottish public sector strategies, plans and programmes (SPPs, whether of a statutory or of a voluntary nature, which are deemed likely to have significant environmental effects. This major extension of the EU SEA Directive by the Scottish Government has been deliberately designed to mainstream sustainable development in Scottish policy formulation. The paper reviews current progress in this direction, raising some issues of principle and practice in the use of SEA before considering how SEA can be combined with environmental modeling techniques to deliver the challenging climate change targets adopted by Scottish public bodies. .

    Wheat and cotton are important food and cash crops often grown in rotation on black, grey and red clay soil, in Australia. The common practice of nitrogen and phosphate fertilizers have been solely in the form of agrochemicals, however, a few growers have incorporated manure or composted plant material into the soil before planting. While the cotton yield in studied farms was comparable, we found that the use of such organic amendments significantly enhanced the pool of nitrogen cycling genes, suggesting increased potential of soil microbial function as well as increased microbial metabolic diversity and abundance. Therefore, the regular use of organic amendments contributed to improved soil sustainability.

    2006-01-01

    It is now well accepted that there are significant challenges to realising the widespread and self-sustaining implementation of sustainable urban water management. It is argued that these challenges are entrenched within the broader socio-political framework, yet often unsuccessfully addressed within the more narrow scope of improving technical knowledge and design capacity. This hypothesis is investigated through a comparative analysis of three independent research projects investigating different dimensions of the water cycle, including stormwater management in Australia and sanitary waste management and implementation of innovative technologies in the U.K. The analysis reveals significant and common socio-political impediments to improved practice. It was evident that the administrative regime, including implementing professionals and institutions, appears to be largely driven by an implicit expectation that there is a technical solution to solve water management issues. This is in contrast to addressing the issues through broader strategies such as political leadership, institutional reform and social change. It is recognised that this technocratic culture is inadvertently underpinned by the need to demonstrate implementation success within short-term political cycles that conflict with both urban renewal and ecological cycles. Addressing this dilemma demands dedicated socio-technical research programs to enable the much needed shift towards a more sustainable regime.

  6. Towards sustainable parasite control practices in livestock production with emphasis in Latin America.

    2011-08-04

    Endo and ectoparasites of domestic ruminants directly or indirectly contribute to reduce sustainability affecting food security in subsistence or small scale farming systems, food safety (food borne diseases and pesticide residues), environment (pesticides, pollution and ecotoxicity) and farmer's equity (limited or uneven access to relevant technical information/training). This is especially true for some regions of Latin America where there still are huge areas of natural grazing land for cattle, sheep and goats. Sustainable parasite control is not an absolute concept given the different regions and productive systems of the world and therefore, could have different levels of adoption and impact on farmers. This article develops a conceptual framework to better understand where each region or country is situated in terms of attaining a reasonable increase in animal production while preserving sustainability. Within this context the capacity to prioritize the target parasite species for control according to local epidemiology and production systems, the early diagnosis and monitoring of parasite resistance as well as the availability of well trained field professionals acquire a major role, creating an enabling environment for present and future decision support system approaches. Until new and different means of controlling parasites become available; the challenge is to utilize Good Animal Husbandry Practices and Integrated Parasite Management (IPM) principles in a pragmatic way allowing the rational use of pesticides.

    Food availability and access are strongly affected by seasonality in Ethiopia. However, there are little data on seasonal variation in Infant and Young Child Feeding (IYCF) practices and malnutrition among 6-23 months old children in different agro-ecological zones of rural Ethiopia. Socio-demographic, anthropometry and IYCF indicators were assessed in post- and pre-harvest seasons among children aged 6-23 months of age randomly selected from rural villages of lowland and midland agro-ecological zones. Child stunting and underweight increased from prevalence of 39.8% and 26.9% in post-harvest to 46.0% and 31.8% in pre-harvest seasons, respectively. The biggest increase in prevalence of stunting and underweight between post- and pre-harvest seasons was noted in the midland zone. Wasting decreased from 11.6% post-harvest to 8.5% pre-harvest, with the biggest decline recorded in the lowland zone. Minimum meal frequency, minimum acceptable diet and poor dietary diversity increased considerably in pre-harvest compared to post-harvest season in the lowland zone. Feeding practices and maternal age were predictors of wasting, while women's dietary diversity and children age was predictor of child dietary diversity in both seasons. There is seasonal variation in malnutrition and IYCF practices among children 6-23 months of age with more pronounced effect in midland agro-ecological zone. A major contributing factor for child malnutrition may be poor feeding practices. Health information strategies focused on both IYCF practices and dietary diversity of mothers could be a sensible approach to reduce the burden of child malnutrition in rural Ethiopia.

    More than 7 million US high school students play sports. To compare practice and competition injury rates and patterns in 5 boys' sports (football, soccer, basketball, wrestling, and baseball) and 4 girls' sports (soccer, volleyball, basketball, and softball) during the 2005-2006 school year. Prospective injury surveillance study. Injury data were collected from 100 nationally representative United States high schools via High School RIO (Reporting Information Online). Athletes from participating high schools injured while participating in a school-sanctioned practice or competition in one of the above sports. Practice and competition injury rates, body site, diagnosis, and severity. High school athletes participating in these 9 sports at participating schools sustained 4350 injuries during the 2005-2006 school year, which corresponds to an estimated 1 442 533 injuries nationally. The rate of injury per 1000 athlete-exposures was higher in competition (4.63) than in practice (1.69) (rate ratio [RR] = 2.73, 95% confidence interval [CI] = 2.58, 2.90). Of all sports, football had the highest competition (12.09) and practice (2.54) injury rates per 1000 athlete-exposures. Compared with injuries sustained during practice, higher proportions of competition injuries were head/face/neck injuries (proportion ratio [PR] = 1.61, 95% CI = 1.34, 1.94), particularly in boys' soccer (PR = 7.74, 95% CI = 2.53, 23.65) and girls' basketball (PR = 6.03, 95% CI = 2.39, 15.22). Competition injuries were more likely to be concussions (PR = 2.02, 95% CI = 1.56, 2.62), especially in boys' soccer (PR = 6.94, 95% CI = 2.01, 23.95) and girls' basketball (PR = 5.83, 95% CI = 2.06, 16.49). Higher proportions of competition injuries caused the athlete to miss more than 3 weeks of play (PR = 1.28, 95% CI = 1.08, 1.52), particularly in baseball (PR = 3.47, 95% CI = 1.48, 8.11) and volleyball (PR = 2.88, 95% CI = 1.01, 8.24).

    Agroforestry is a sustainable land use system with a promising potential to sequester atmospheric carbon into soil. This system of land use distinguishes itself from the other systems, such as sole crop cultivation and afforestation on croplands only through its potential to sequester higher amounts of carbon (in the above- and belowground tree biomass) than the aforementioned two systems. According to Kyoto protocol, agroforestry is recognized as an afforestation activity that, in addition to sequestering carbon dioxide (CO 2 ) to soil, conserves biodiversity, protects cropland, works as a windbreak, and provides food and feed to human and livestock, pollen for honey bees, wood for fuel, and timber for shelters construction. Agroforestry is more attractive as a land use practice for the farming community worldwide instead of cropland and forestland management systems. This practice is a win-win situation for the farming community and for the environmental sustainability. This review presents agroforestry potential to counter the increasing concentration of atmospheric CO 2 by sequestering it in above- and belowground biomass. The role of agroforestry in climate change mitigation worldwide might be recognized to its full potential by overcoming various financial, technical, and institutional barriers. Carbon sequestration in soil by various agricultural systems can be simulated by various models but literature lacks reports on validated models to quantify the agroforestry potential for carbon sequestration.

    Full Text Available Policies and actions that come from higher scale structures, such as international bodies and national governments, are not always compatible with the realities and perspectives of smaller scale units including indigenous communities. Yet, it is at this local social-ecological scale that mechanisms and solutions for dealing with unpredictability and change can be increasingly seen emerging from across the world. Although there is a large body of knowledge specifying the conditions necessary to promote local governance of natural resources, there is a parallel need to develop practical methods for operationalizing the evaluation of local social-ecological systems. In this paper, we report on a systemic, participatory, and visual approach for engaging local communities in an exploration of their own social-ecological system. Working with indigenous communities of the North Rupununi, Guyana, this involved using participatory video and photography within a system viability framework to enable local participants to analyze their own situation by defining indicators of successful strategies that were meaningful to them. Participatory multicriteria analysis was then used to arrive at a short list of best practice strategies. We present six best practices and show how they are intimately linked through the themes of indigenous knowledge, local governance and values, and partnerships and networks. We highlight how developing shared narratives of community owned solutions can help communities to plan governance and management of land and resource systems, while reinforcing sustainable practices by discussing and showcasing them within communities, and by engendering a sense of pride in local solutions.

    Full Text Available Aflatoxin contamination in groundnut is an important qualitative issue posing a threat to food safety. In our present study, we have demonstrated the efficacy of certain good agricultural practices (GAPs in groundnut, such as farmyard manure (5 t/ha, gypsum (500 kg/ha, a protective irrigation at 90 days after sowing (DAS, drying of pods on tarpaulins after harvest in farmers’ fields. During 2013–2015, 89 on-farm demonstrations were conducted advocating GAPs, and compared with farmers’ practices (FP plots. Farmers’ awareness of GAPs, and knowledge on important aspects of groundnut cultivation, were also assessed during our experimentation in the selected villages under study. Pre-harvest kernel infection by Aspergillus flavus, aflatoxin contamination, and pod yields were compared in GAPs plots, vis-à-vis FP plots. The cost of cultivation in both the plots was calculated and compared, based on farmer’s opinion surveys. Results indicate kernel infections and aflatoxins were significantly lower, with 13–58% and 62–94% reduction, respectively, in GAPs plots over FP. Further, a net gain of around $23 per acre was realized through adoption of GAPs by farmers besides quality improvement of groundnuts. Based on our results, it can be concluded that on-farm demonstrations were the best educative tool to convince the farmers about the cost-effectiveness, and adoptability of aflatoxin management technologies.

    Full Text Available Abstract The recent years has arisen a global discussion in relation with how to incorporate sustainability at a business level. Corporate sustainability is a multidimensional concept, is the translation of Sustainable Development concept at a business level. Sustainability in organizations must be managed and assessed by decision makers, for that reason a multi-criteria sustainability performance measurement is necessary. The aim of this paper is combine different important tools that helps to make operative corporate sustainability and sustainability performance measurement in Cuban organizations. The combination of Sustainability Balanced Scorecard, multi-criteria decisions models like: Analytic Network Process, and Matrix of Sustainable Strategic Alignment, can help managers in sustainability performance measurement and assessment. The result of this paper focus in a Corporate Sustainability Measurement Network design as a first approach for further sustainability performance measurement systems development emphasizing in multi-criteria analysis.

  15. Drained forest land and mires with thick peat as resources for sustainable peat harvesting in Sweden; Dikad skogsmark och myr med djup torv som resurser foer uthaalligt torvbruk i Sverige

    2006-04-15

    The aims of this study were to (i) calculate the coverage and location of drained peatlands which from an environmental perspective are the most suitable for peat harvesting in Sweden, and (ii) to calculate the volumes of peat on drained and un-drained peatlands as a basis for an analysis of the potential for sustainable future peat harvesting in the country. Data were selected from the Swedish National Forest Inventory of Forests, more specifically from the National Forest Inventory 1993-1997 and 1998-2002, and from the Swedish Forest Soil Inventory 2003-2004. The area of productive forest land covered with peat thicker than 1 m comprises about 700,000 ha, half on drained and half on un-drained sites. Deep peat layers are especially common in the provinces of Smaaland and Vaesterbotten (southern and coastal parts, respectively). The area of non-productive mires with thick (> 1 m) peat cover encompasses ca 2.6 million ha. About 200,000 of these mires are drained. Half of the drained forest land with thick peat, about 180,000 ha, belongs to peatland sites greater than 10 ha which can be regarded as the minimum size for profitable peat harvesting. As for the drained non-productive mires, less than a quarter of the area has to be rejected as potential sites for harvesting because of being too small size. In total, about 180,000 ha of drained forest land and 165,000 ha of drained non-productive mires with thick peat can be regarded as the country's potential for peat harvesting. The emission of greenhouse gases is greater from highly productive than from low-productive drained peatlands. The dominant part of the drained forest land belongs to the three most productive site types. A change in the ongoing land use, from forestry to peat harvesting, should be least expensive immediately after final felling of a mature forest (and before the establishment of a new generation of trees). The stands on the drained productive forest land are fairly evenly distributed

    The focus of REDD+ is sensu stricto on maintaining forest carbon stocks. We extend the scope of sustainable management of forest from forests to timber utilization, and study carbon offsets resulting from the utilization of harvested timber for bio energy or harvested wood products (HWPs). The emission budget of harvesting operations depends on the loss of standing biomass by timber extracted from the forest site and logging losses on the one side, and on the other on the wood end use and the utilization of processing residues. We develop two scenarios to quantify the magnitude of CO2 emissions by (1) energetic utilization, and (2) energetic and material utilization of harvested timber and compare the substitution effects for different fossil energy sources. The direct energetic use of harvested timber does not compensate for the losses of forest carbon stock. Logging residuals and displacement factors reflecting different wood use constitute by far the most important factor in potential emission reductions. Substitution effects resulting from energetic use of mill residuals and from HWPs have only a subordinated contribution to the total emissions as well as the type of fossil fuel utilized to quantify substitution effects. Material substitution effects associated with harvested wood products show a high potential to increase the climate change benefits. The observation and perception of REDD+ should not be restricted to sustainable management and reduced impact logging practices in the forest domain but should be extended to the utilization of extracted timber. Substitution effects from material and energetic utilization of harvested timber result in considerable emission reductions, which can compensate for the loss of forest carbon, and eventually contribute to the overall climate change mitigation benefits from forestry sector.

  17. Evolution of Forest Systems: the Role of Biogeochemical Cycles in Determining Sustainable Forestry Practices

    Directory of Open Access Journals (Sweden)

    Werner T. Flueck

    2009-12-01

    Full Text Available The exploitation of natural resources such as forests leads to sustainable forest management (SFM. The key question is how to define and parametrize "sustainable use." Promoting forest use that conserves spatial characteristics of forest landscapes and the structure and composition of forest stands was proposed as a way of maintaining elements of biodiversity such as species richness and genetic variation. However, to establish the parameter space for sustainable forest use, it is essential to consider the nutrient requirements of forest systems, that is, plants and animals, the need for fertilizer application, and the effects on biogeochemical cycles, a cornerstone of biological evolution and, thus, biodiversity. The use of forest products is inevitably tied to exporting biomass from those ecosystems because products are used elsewhere, thus changing natural practically steady-state ecosystems to open ones. Continued biomass export results in soil acidification and nutrient removal. Among macronutrients, phosphorus takes a key position, but several others have been shown to be depleted in managed-forest systems. Micronutrients are more crucial for forest-dwelling animals, particularly those nutrients that are only essential to animals. Depletion of their reserves, selenium for instance, through biomass export will not affect plants, and initial subclinical effects on animals are difficult to detect. The generalized effect may be reflected in changing rates of recruitment or disease resistance, and thus ecosystem processes. Forest products and their export reduces soil-nutrient reserves, and slash burning and water runoff further add to cumulative losses of several minerals. Such impacts from forest products need to be addressed, particularly for mammals and their unique needs for several microelements. Biogeochemical cycles disturbed by exporting forest products will affect plants and animals and, therefore, ecosystems and their processes, and

    Despite the abundance of past home care projects and the maturity of the technologies used, there is no widespread dissemination as yet. The absence of accepted standards and thus interoperability and the inadequate integration into transinstitutional health information systems (tHIS) are perceived as key factors. Based on the respective literature and previous experiences in home care projects we propose an architectural model for home care as part of a transinstitutional health information system using the HL7 clinical document architecture (CDA) as well as the HL7 Arden Syntax for Medical Logic Systems. In two short case studies we describe the practical realization of the architecture as well as first experiences. Our work can be regarded as a first step towards an interoperable - and in our view sustainable - home care architecture based on a prominent document standard from the health information system domain.

    Full Text Available This article addresses development for information literacy (IL practice through building internal library organizational culture. Using an analysis of relevant literature and reflection on lived experience, the authors explore issues and concepts for instruction librarians and leaders to consider as they advance and sustain IL initiatives. Through a lens of second order change the article proposes change agency theory and organizational development as theoretical approaches; calling on librarians to adopt roles and techniques that honor personal learning and continuing education while simultaneously focusing on student learning. It additionally suggests a flexible roadmap for managed change processes including organizational assessment techniques, inspiration for conversations and inclusive dialogues, reasons for and ways to address resistance, and steps to implement action plans. The authors conclude IL initiatives will be more effective if supported by an internal library culture that is embraced and implemented by knowledgeable instruction librarians and their leaders.

    Full Text Available The study identified the sustainable land management practices being used by farmers in Osun State. The analysis determinedthe factors associated with the use of the land management practices and the best of the practices being used. Multistage sampling technique was used to select 256 farmers from eight Local Government Areas (LGAs of the State. Eight different enterprise farmers were selected from the LGAs and four farmers were purposively selected from each enterprise. Data collected were described with frequency, mean and standard deviation while factor and regression analyses were used to make inferences for the study. The results revealed that the mean age of the farmers was 48.0±10.3, majority was married and about 60% were male. The mean household size was 6.6±2.8 and majority was able to read and write. The study identified 35 sustainable land management practices which were known to the farmers, out of which 28 were being practiced. Seven factors associated with the use ofsustainable land management practices are:farming experience, economic, educational, accessibility to inputs, personal and family characteristics as well as soil fertility status. These factors were statistically significant (P < .05 to the use of soil management practices. Weconcluded that the level of awareness and use of sustainable land management practices in the state was still below the expected standard.

    Open raceway ponds are regarded as the most economically viable option for large-scale cultivation of microalgae for low to mid-value bio-products, such as biodiesel. However, improvements are required including reducing the costs associated with harvesting biomass. There is now a growing interest in exploiting natural ecological processes within biotechnology. We review how chemical cues produced by algal grazers induce colony formation in algal cells, which subsequently leads to their sedimentation. A statistical meta-analysis of more than 80 studies reveals that Daphnia grazers can induce high levels of colony formation and sedimentation in Scenedesmus obliquus and that these natural, infochemical induced sedimentation rates are comparable to using commercial chemical equivalents. These data suggest that natural ecological interactions can be co-opted in biotechnology as part of a promising, low energy and clean harvesting method for use in large raceway systems.

    The future of hospital social work departments depends on their ability to demonstrate their effectiveness, efficiency, and consequently, their value to their host organizations. In order to demonstrate and enhance social work's contribution, research activities of various kinds must be encouraged. These include research consumption as well as production and utilization by clinicians, supervisors, managers, and administrators. The authors sought to develop a sustainable research environment in a large social work department of an academic health system. Continued work is needed to understand practice-research "best practices" within hospitals and how to ensure their sustainability within an ever changing health care environment.

    Organizations are increasingly using sustainability reports to inform their stakeholders and the public about their sustainability practices. We apply topic modelling to 9,514 sustainability reports published between 1999 and 2015 in order to identify common topics and, thus, the most common practices described in these reports. In particular, we identify forty-two topics that reflect sustainability and focus on the coverage and trends of economic, environmental, and social sustainability topics. Among the first to analyse such a large amount of data on organizations' sustainability reporting, the paper serves as an example of how to apply natural language processing as a strategy of inquiry in sustainability research. The paper also derives from the data analysis ten propositions for future research and practice that are of immediate value for organizations and researchers.

  9. Sustainable and Practical Firmware Upgrade for Wireless Access Point Using Password-Based Authentication

    2016-08-01

    Full Text Available Wireless access points (WAPs are devices that provide Internet connectivity to devices such as desktops, laptops, smartphones, and tablets. Hence, it is important to provide sufficient availability to devices and security for the traffic that is routed by a WAP. However, attackers can decrease the network bandwidth or obtain the traffic including private data such as search histories, login information, and device usage patterns by exploiting the vulnerabilities in firmware upgrades to install malicious firmware. To address this problem, we propose a sustainable and practical firmware upgrade for a WAP using password-based authentication. The proposed upgrade protocol ensures security by adding freshness to the firmware whenever a firmware upgrade occurs. This freshness is different for each event and each firmware; therefore, even if the freshness of one firmware is exposed, the others are secure. In addition, confidentiality, integrity, and authentication are ensured. Furthermore, the proposed protocol can be easily implemented and adapted to WAPs. Experiments are performed to evaluate the upgrade time, resource usage, and code size in wired and wireless connected environments by implementing a prototype and analyzing the security of the protocol. The results show that the proposed upgrade is secure and practical.

    2003-07-01

    Technically, most people agree that conserving soil organic matter and completing nutrient cycles by applying animal manures, treated organic wastes and biosolids to land is the most sustainable option in the majority of situations. It is also generally the least expensive. There has been a huge amount of research into the hazards, and this has concluded that the risks can be managed to acceptable levels. But there has been insufficient attention to communicating this knowledge, as so often in the scientific and technological arena. Perception is reality. Nowadays compliance with regulations (whilst essential) is not enough; public and stakeholder attitudes can be of decisive importance. Sometimes policy-makers speculate what public attitudes might be without really asking them. This paper will describe an initiative to create a partnership open to anybody with an interest in the use of organic materials on land to develop consensus on good practice and to share knowledge. It summarises an attitude survey of more than 140 organisations, which was then debated at a workshop in July 2002. The conclusion from this study was that all parties considered a partnership is essential to share knowledge, build mutual trust and agree practices that are welcomed by all in the food chain. The paper will describe the steps to establishing a partnership organisation, its aims and objectives, the work to date and the plans for the future. The Environment Agency considers this very important and has largely funded the work to date. The consequences of failing to establish welcomed practices would be loss the facility to use organic resources on land. (author)

Nursing staff were observed regarding the practice of ecologically sustainable actions during medication processes (n = 324 cases for each group (pre and post-intervention)) through a data collection instrument. The processes analyzed involved 99 professionals in the pre-intervention phase and 97 in the post-intervention phase. Data were analyzed quantitatively and the association of variables was accomplished by means of statistical inference, according to the nature of the related variables. the education level was the only characteristic that showed to be relevant to an increase in sustainable practices, with a statistically significant difference (p = 0.002). When comparing before and after the intervention, there was an increase in environmentally friendly actions with statistically significant differences (p = 0.001). the results suggest that institutions should encourage and invest in formal education, as well as training of health professionals to promote sustainable practices in the hospital. verificar la correlación entre las características de los profesionales y la práctica de acciones sustentables en los procesos de medicación en una UTI y determinar si intervenciones como capacitación y concientización logran promover la práctica de acciones sustentables por el equipo de enfermería en el hospital. estudio antes y después usando la metodología Lean Seis Sigma, aplicada en una unidad de terapia intensiva.

  3. Development and implementation of the Good Neighbor Agreement (GNA) practice in the USA sustainable mining development.

    Science.gov (United States)

    Masaitis, Alexandra

    2014-05-01

    New economic, environmental and social challenges for the mining industry in the USA show the need to implement "responsible" mining practices that include improved community involvement. Conflicts which occur in the US territory and with US mining companies around the world are now common between the mining proponents, NGO's and communities. These conflicts can sometimes be alleviated by early development of modes of communication, and a formal discussion format that allows airing of concerns and potential resolution of problems. One of the methods that can formalize this process is to establish a Good Neighbor Agreement (GNA), which deals specifically with challenges in relationships between mining operations and the local communities. It is a new practice related to mining operations that are oriented toward social needs and concerns of local communities that arise during the normal life of a mine, which can achieve sustainable mining practices. The GNA project being currently developed at the University of Nevada, USA in cooperation with the Newmont Mining Corporation has a goal of creating an open company/community dialog that will help identify and address sociological and environmental concerns associated with mining. Discussion: The Good Neighbor Agreement currently evolving will address the following: 1. Identify spheres of possible cooperation between mining companies, government organizations, and NGO's. 2. Provide an economically viable mechanism for developing a partnership between mining operations and the local communities that will increase mining industry's accountability and provide higher levels of confidence for the community that a mine is operated in a safe and sustainable manner. Implementation of the GNA can help identify and evaluate conflict criteria in mining/community relationships; determine the status of concerns; determine the role and responsibilities of stakeholders; analyze problem resolution feasibility; maintain the community

    Full Text Available Challenges related to development, deployment, and maintenance of reusable software for science are becoming a growing concern. Many scientists’ research increasingly depends on the quality and availability of software upon which their works are built. To highlight some of these issues and share experiences, the First Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE1 was held in November 2013 in conjunction with the SC13 Conference. The workshop featured keynote presentations and a large number (54 of solicited extended abstracts that were grouped into three themes and presented via panels. A set of collaborative notes of the presentations and discussion was taken during the workshop. Unique perspectives were captured about issues such as comprehensive documentation, development and deployment practices, software licenses and career paths for developers. Attribution systems that account for evidence of software contribution and impact were also discussed. These include mechanisms such as Digital Object Identifiers, publication of “software papers”, and the use of online systems, for example source code repositories like GitHub. This paper summarizes the issues and shared experiences that were discussed, including cross-cutting issues and use cases. It joins a nascent literature seeking to understand what drives software work in science, and how it is impacted by the reward systems of science. These incentives can determine the extent to which developers are motivated to build software for the long-term, for the use of others, and whether to work collaboratively or separately. It also explores community building, leadership, and dynamics in relation to successful scientific software.

    2015-01-01

    Full Text Available The purpose of this paper is to evolve a sustainable practical model of employability skills that is sure to capture relevant learning aspects of a particular occupational discipline to be used as framework for Undergraduate students to develop their employability potentials. The study was conducted in three Universities and Polytechnics each with three multi-national companies. Data were collected using semi-structured interviews. Using purposeful sampling 18 academic staff and 3 professionals representing company employers were selected as the study participants. The study evolved a model that is work-based, explicit in its outcome, fully articulated and realistic in terms of employability skill experiences. The proposed model can be used to establish a common higher education programme or curricula that is work-based and skill experience oriented, that can encourage students in higher education to think about work place learning more explicitly and reflectively, that will in turn help them to develop a broad range of knowledge, skills, attitudes, and values, each of which ultimately contribute in some manner to graduate employability.  The paper is considered a contribution to the evolution and growth of knowledge on the linkage between higher education and workplace, through which the ‘skill gap’ occurring between the demand of employment and the level of educational preparation of graduates can be bridged.

    Full Text Available This paper is primarily concerned with alternative teaching methodologies. Creative teaching methodologies place the student at the center of the learning process. This paper is a case study of 'Orion - promotion of the Vučedol culture' project as a self-sustainable cultural product. The primary goal of the project is the promotion of heritage through cultural tourism. The 'Orion' project was launched in cooperation with third year undergraduate students at the Department of Tourism of VERN University of Applied Sciences from Zagreb, as part of the Event Management and Marketing course (March to June 2014. Inspired by the Vučedol archaeological site, historical data and lectures on the Vučedol culture and the oldest Indo-European calendar called 'Orion' the students have developed a plan for a two-day festival that would take place in Vinkovci, Croatia and world include a scientific conference, cultural and artistic program, presentation of local cuisine, creative workshops, and promotion of local crafts. This paper reinforces the need for imaginative thinking in education for tourism. The variety of ways in which creative teaching practices can be used is infinite and this case study presents only a small contribution.

    2007-08-01

    Millions of hectares of future timber concessions are slated to be implemented within large public forests under the forest law passed in 2006 by the Brazilian Congress. Additional millions of hectares of large, privately owned forests and smaller areas of community forests are certified as well managed by the Forest Stewardship Council, based on certification standards that will be reviewed in 2007. Forest size and ownership are two key factors that influence management objectives and the capacity of forest managers to achieve them. Current best ecological practices for timber production from Brazil's native Amazon forests are limited to reduced-impact logging (RIL) systems that minimize the environmental impacts of harvest operations and that obey legal restrictions regarding minimum diameters, rare species, retention of seed trees, maximum logging intensity, preservation of riparian buffers, fire protection, and wildlife conservation. Compared with conventional, predatory harvesting that constitutes >90% of the region's timber production, RIL dramatically reduces logging damage and helps maintain forest cover and the presence of rare tree species, but current RIL guidelines do not assure that the volume of timber removed can be sustained in future harvests. We believe it is counterproductive to expect smallholders to subscribe to additional harvest limitations beyond RIL, that larger private forested landholdings managed for timber production should be sustainable with respect to the total volume of timber harvested per unit area per cutting cycle, and that large public forests should sustain volume production of individual harvested species. These additional requirements would improve the ecological sustainability of forest management and help create a stable forest-based sector of the region's economy, but would involve costs associated with lengthened cutting cycles, reduced harvest intensities, and/or postharvest silviculture to promote adequate growth and

  10. Harvesting effects, recovery mechanisms, and management strategies for a long-lived and structural precious coral.

    Full Text Available Overexploitation is a major threat for the integrity of marine ecosystems. Understanding the ecological consequences of different extractive practices and the mechanisms underlying the recovery of populations is essential to ensure sustainable management plans. Precious corals are long-lived structural invertebrates, historically overfished, and their conservation is currently a worldwide concern. However, the processes underlying their recovery are poorly known. Here, we examined harvesting effects and recovery mechanisms of red coral Corallium rubrum by analyzing long-term photographic series taken on two populations that were harvested. We compared the relative importance of reproduction and re-growth as drivers of resilience. Harvesting heavily impacted coral populations causing large decreases in biomass and strong size-class distribution shifts towards populations dominated by small colonies. At the end of the study (after 4 and 7 years only partial recovery was observed. The observed general pattern of low recruitment and high mortality of new recruits demonstrated limited effects of reproduction on population recovery. Adversely, low mortality of partially harvested adults and a large proportion of colonies showing new branches highlighted the importance of re-growth in the recovery process. The demographic projections obtained through stochastic models confirmed that the recovery rates of C. rubrum can be strongly modulated depending on harvesting procedures. Thus, leaving the basal section of the colonies when harvesting to avoid total mortality largely enhances the resilience of C. rubrum populations and quickens their recovery. On the other hand, the high survival of harvested colonies and the significant biomass reduction indicated that abundance may not be an adequate metric to assess the conservation status of clonal organisms because it can underestimate harvesting effects. This study highlights the unsustainability of current

  11. An Analytical Assessment of Assurance Practices in Social Environmental and Sustainable Reporting in the United Kingdom and North America

    2010-01-01

    Full Text Available The objective of this study is to continue and extend previous studies in evaluating the extent to which current assurance practices promote transparency and accountability to stakeholders. This is carried out by conducting an empirical analysis of the content of assurance statements accompanying a sample of non-financial reports short-listed for the Association of Chartered Certified Accountants (ACCA U.K. Sustainability Reporting Award and the CERES-ACCA Sustainability Reporting Award from 2006 to 2008. The findings of this study show that several new trends in social, environmental and sustainability assurance can be observed. Firstly, accountants tend to limit their intended readership to management only and state a disclaimer for other potential readers. This diminishes the transparency and stakeholder accountability of the reporting. Secondly, there is even stronger evidence that management has the control over the scope of the assurance engagement and over what information gets publicly disclosed. The evidence is shown in the fact that in many assurance statements prepared by accountants, only selected parts of the reports are being assured, with no indication that it is not management who selects these parts. Finally, the recent practices of assurance engagements represented by the sample in this study have not improved the transparency and stakeholder accountability of social, environmental and sustainable reporting. Similar to the two previous studies, we assert that a generally accepted standard is needed to promote assurance statements that add meaningful values to the reliability of social, environmental and sustainability reporting.

    Many healthcare innovations are not sustained over the long term, wasting costly implementation efforts and often desperately-needed initial improvements. Although there have been advances in knowledge about innovation implementation, there has been considerably less attention focused on understanding what happens following the early stages of change. Research is needed to determine how to improve the 'staying power' of healthcare innovations. As almost no empirical knowledge exists about innovation sustainability in nursing, the purpose of our study was to understand how a nursing best practice guidelines (BPG) program was sustained over a long-term period in an acute healthcare centre. We conducted a qualitative descriptive case study to examine the program's sustainability at the nursing department level of the organization. The organization was a large, urban, multi-site acute care centre in Canada. The patient safety-oriented BPG program, initiated in 2004, consisted of an organization-wide implementation of three BPGs: falls prevention, pressure ulcer prevention, and pain management. Data were collected eight years following program initiation through 14 key informant interviews, document reviews, and observations. We developed a framework for the sustainability of healthcare innovations to guide data collection and content analysis. Program sustainability entailed a combination of three essential characteristics: benefits, institutionalization, and development. A constellation of 11 factors most influenced the long-term sustainability of the program. These factors were innovation-, context-, leadership-, and process-related. Three key interactions between factors influencing program sustainability and characteristics of program sustainability accounted for how the program had been sustained. These interactions were between: leadership commitment and benefits; complementarity of leadership actions and both institutionalization and development; and a

    Studies showing sustained improvements in the delivery of clinical preventive services are limited. Fewer studies demonstrate sustained improvements among independent practices that are not affiliated with hospitals or integrated health systems. This study examines the continued improvement in clinical quality measures for a group of independent primary care practices using electronic health records (EHRs) and receiving technical support from a local public health agency. We analyzed clinical quality measure performance data from a cohort of primary care practices that implemented an EHR at least 3 months before October 2009, the study baseline. We assessed trends for 4 key quality measures: antithrombotic therapy, blood pressure control, smoking cessation intervention, and hemoglobin A1c (HbA1c) testing based on monthly summary data transmitted by the practices. Of the 151 practices, 140 were small practices and 11 were community health centers; average time using an EHR was 13.7 months at baseline. From October 2009 through October 2011, average rates increased for antithrombotic therapy (from 58.4% to 74.8%), blood pressure control (from 55.3% to 64.1%), HbA1c testing (from 46.4% to 57.7%), and smoking cessation intervention (from 29.3% to 46.2%). All improvements were significant. During 2 years, practices showed significant improvement in the delivery of several key clinical preventive services after implementing EHRs and receiving support services from a public health agency.

    2015-03-01

    Full Text Available To better satisfy various stakeholders, firms are seeking integrated practices that can enhance their sustainability performance, also well known as the Triple Bottom Line (3BL. The fashion industry exhibits potential conflicts with the spirit of sustainability because of the waste created by high levels of demand uncertainty and the extant usage of resources in production. Literature suggests that selected stand-alone practices of lean, green, and Corporate Social Responsibility (CSR management systems have a positive impact on firm sustainability performance. However, how the combination of selected practices from these three management systems impacts the 3BL remains unclear. Based on case studies, we build an integrated sustainable practices model incorporating the most popular lean, green, and social practices and develop propositions for future tests. Our framework suggests the implementation of integrated practices would have a stronger influence on 3BL performance than individual practice implementation.

    Kwok, Cara; Bates, Kimberly A; Ng, Eddy S

    2016-05-01

    This paper seeks to identify gaps within nursing collective agreements for opportunities to implement practices to sustain the nursing workforce. Since the majority of nurses in Canada are unionised, some of the strategies recommended in the literature to cope with nursing shortage may not apply to unionised nurses, making collective agreements a potential source for designing practices that can mitigate the impact of ageing nurses. Nine major collective agreements for registered nurses in each province governing the nursing employment relationship were analysed to see if different practices were already addressed in the collective agreements. Five such practices were identified, including: providing more mentorship opportunities; encouraging nurses who are eligible to retire to remain in the nursing workforce; attracting internationally trained nurses; implementing operational changes that include process improvements or new technologies; and empowering nurses through flexibility in work schedules. If collective agreements are silent in any of the strategies identified in the literature, health-care organisations can adopt these practices without violating the collective agreements. Non-unionised health-care organisations can also benefit from learning about these policies and practices to assist in managing and sustaining an ageing nursing workforce. © 2016 John Wiley & Sons Ltd.

    Full Text Available A survey was conducted in order to assess the losses of maize under farmers’ storage conditions in the Western hills of Nepal in 2014. The survey area included Thanapati Village Development Committee (VDC of Gulmi, Aalamdebi VDC of Syangja, Khasauli VDC of Palpa and Baglung municipality-12, Baglung district. Primary information was collected through semi-structured questionnaires among the heterogenous groups of the farming communities. Survey revealed that about 61% respondents reported the storage pest as the major pests and about 12% respondents reported that field pests as the major pests in the western hills. Maize weevil (Sitophylus zeamais Mostsch. and Angoumois grain moth (Sitotroga cerealella Oliv. were found to be major storage insect pests in surveyed areas. Majority of respondents (39% presumed on 10-20% losses during storage. Among the other biotic factors, farmers ranked insect (42%, weeds (32% and diseases (17% respectively. Maize storage methods had distinct among the surveyed areas compared with Baglung district to other surveyed areas. In Baglung, about (73% farmers had stored maize in the form of grain whereas in Palpa, Gulmi and Syangja, about (77% farmers had practice of storing maize with husk for 5-7 months. Approximately, 40% respondents were using open floor in upper stair “Aanti”as a major maize storage place in Palpa, Gulmi and Syangja whereas almost (79% of respondents were using sacks to store shelled grains in Baglung. Hence, there is ample opportunity to reduce the storage losses of maize depending upon the existing situation.

    Dielectric elastomers offer the promise of energy harvesting with few moving parts. Power can be produced simply by stretching and contracting a relatively low-cost rubbery material. This simplicity, combined with demonstrated high energy density and high efficiency, suggests that dielectric elastomers are promising for a wide range of energy harvesting applications. Indeed, dielectric elastomers have been demonstrated to harvest energy from human walking, ocean waves, flowing water, blowing wind, and pushing buttons. While the technology is promising, there are challenges that must be addressed if dielectric elastomers are to be a successful and economically viable energy harvesting technology. These challenges include developing materials and packaging that sustains long lifetime over a range of environmental conditions, design of the devices that stretch the elastomer material, as well as system issues such as practical and efficient energy harvesting circuits. Progress has been made in many of these areas. We have demonstrated energy harvesting transducers that have operated over 5 million cycles. We have also shown the ability of dielectric elastomer material to survive for months underwater while undergoing voltage cycling. We have shown circuits capable of 78% energy harvesting efficiency. While the possibility of long lifetime has been demonstrated at the watt level, reliably scaling up to the power levels required for providing renewable energy to the power grid or for local use will likely require further development from the material through to the systems level.

  3. Towards an ecology of eating disorders: creating sustainability through the integration of scientific research and clinical practice.

    2010-01-01

    The field of eating disorders is currently at a crossroads and faces important challenges of sustainability. These challenges include problems with the current diagnostic classification of eating disorders and the divide between scientific research and clinical practice. If not addressed, there is a danger that the field will fail to evolve adaptively, risking increased stagnation and reduced relevance. To meet these challenges, researchers and clinicians must work toward a more holistic ecology of eating disorders based on the interaction of theory, research and practice. The present paper proposes six steps towards increased sustainability based on developing clinically relevant diagnosis, using systematic quality assurance, expanding the scope of treatment research and the definition of evidence, promoting therapist development, as well as stimulating diversity and discourse. If we rise to the occasion and face these challenges, then we will be better equipped to meet the evolving needs of clinicians, researchers, and most importantly patients.

    This work presents the strategy adopted by the Research and Development Center of PETROBRAS - CENPES to disseminate the culture of social responsibility and sustainable development. It is associated to the strategic objectives of the company and is based on the integration of diagnosis, sensibility and training actions of CENPES manpower. The objective is to promote appropriate postures toward sustainability which will be manifested from individual attitudes in daily actions inside the company - as for instance the responsible consumption of paper and water - until the election of sustainability criteria, with emphasis in the social and environmental variables that will contribute to research and basic engineer projects evaluation. The diagnosis phase considers two fundamental actions: to check the 'state of the art' of the internal culture and to map the several relationship groups or stakeholders. In the sensibility stage, the objective is to offer knowledge and information about the theme using different approaches some times continued, other times segmented, through specific and appropriate media. Finally, the training of the researchers and sustainability concepts promoter and multiplier agents will close the virtuous cycle that will lead to practice the values proposed in the social responsibility and sustainable development agenda.

  5. Marine Hydrokinetic (MHK) Systems: A Systems Engineering Approach to Select Locations for the Practical Harvest of Electricity from Shallow Water Tidal Currents

    Science.gov (United States)

    Domenech, John

    Due to increasing atmospheric CO2 concentration and its effect on global climates, the United States Environmental Protection Agency (EPA) proposes a Clean Power Plan (CPP) mandating CO2 reductions which will likely force the early retirement of inefficient, aging power plants. Consequentially, removing these plants equates to a shortfall of approximately 66 GW of electricity. These factors add to the looming resource problems of choosing whether to build large replacement power plants or consider alternative energy sources as a means to help close the gap between electricity supply and demand in a given region. One energy source, shallow water tidal currents, represents opportunities to convert kinetic energy to mechanical forms and provide electricity to homes and businesses. Nearly 2,000 National Oceanic Atmospheric Administration (NOAA) tidal current data points from Maine to Texas are considered. This paper, based on systems engineering thinking, provides key attributes (e.g. turbine efficiency, array size, transmission losses) for consideration as decision makers seek to identify where to site Marine Hydrokinetic (MHK) systems and the number of homes powered by the practical harvest of electricity from tidal currents at those locations with given attributes. A systems engineering process model is proposed for consideration as is a regression based equation to estimate MHK machine parameters needed for power a given number of homes.

    2012-11-01

    The need for organizational innovation as a means of improving health-care quality and containing costs is widely recognized, but while a growing body of research has improved knowledge of implementation, very little has considered the challenges involved in sustaining change - especially organizational change led 'bottom-up' by frontline clinicians. This study addresses this lacuna, taking a longitudinal, qualitative case-study approach to understanding the paths to sustainability of four organizational innovations. It highlights the importance of the interaction between organizational context, nature of the innovation and strategies deployed in achieving sustainability. It discusses how positional influence of service leads, complexity of innovation, networks of support, embedding in existing systems, and proactive responses to changing circumstances can interact to sustain change. In the absence of cast-iron evidence of effectiveness, wider notions of value may be successfully invoked to sustain innovation. Sustainability requires continuing effort through time, rather than representing a final state to be achieved. Our study offers new insights into the process of sustainability of organizational change, and elucidates the complement of strategies needed to make bottom-up change last in challenging contexts replete with competing priorities.

    2008-03-01

    The present research integrates core aspects of social identity theory with the theory of planned behaviour to investigate factors influencing engagement in sustainable agricultural practices. Using a two-wave prospective design, two studies were conducted with samples of farmers (N = 609 and N = 259, respectively). At Time 1, a questionnaire survey assessed theory of planned behaviour variables in relation to engaging in riparian zone management (a sustainable agricultural practice). In addition, intergroup perceptions (i.e. relations between rural and urban groups), group norms and group identification were assessed. At Time 2, self-reported behaviour was measured. There was support for the integrated model across both studies. As predicted, past behaviour, attitudes and perceived behavioural control were significant predictors of intentions, and intentions significantly predicted self-reported behaviour. Group norms and intergroup perceptions were also significant predictors of intentions providing support for the inclusion of social identity concepts in the theory of planned behaviour. More supportive group norms were associated with higher intentions, especially for high-group identifiers. In contrast, more negative intergroup perceptions were associated with lower intentions and, unexpectedly, this effect only emerged for low-group identifiers. This suggests that in the context of decisions to engage in riparian zone management, an important sustainable agricultural practice, high identifiers are influenced predominantly by in-group rather than out-group considerations, whereas low identifiers may attend to cues from both the in-group and the out-group when making their decisions.

    Full Text Available In developing regions with high levels of poverty and a dependence on climate sensitive agriculture, studies focusing on climate change adaptation, planning, and policy processes, have gained relative importance over the years. This study assesses the impact of farmer perceptions regarding climate change on the use of sustainable agricultural practices as an adaptation strategy in the Chinyanja Triangle, Southern Africa. In this empirical approach, we adopt methods that account for the plausibility that unmeasured characteristics exist, which are correlated with perceptions and the adoption of Sustainable Agricultural Practices. We use a unique and representative dataset collected in December 2012 and June 2013, from smallholder farmers in the Chinyanja Triangle. The results indicate that farmer’s perceptions significantly influence the use of sustainable agricultural practices. Specifically, we established that farmer perceptions considerably impact the use of grain legume rotations, inorganic fertilizers, compost, and farmyard manure. Our results highlight the need for a serious and perhaps equal consideration of farmer perceptions regarding climate change, as important inputs to climate change adaptation policies targeted at enhancing climatic resilience in smallholder farming communities. This is plausible as the adaptation and pliability of farmers to the effects of climate change should be a social process involving the collective efforts from various stakeholders.

    The extensive use of fertilizers has become one of the most challenging environmental issues in agricultural catchment areas. In order to reduce the negative impacts from agricultural activities and to accomplish the objectives of the European Water Framework Directive we must consider the implementation of sustainable agricultural practices. In this study, we assess sustainable agricultural practices based on reductions in N-fertilizer application rates (from 100% to 0%) and N-application methods (single, split and slow-release) across key agricultural land use classes in the Vouga catchment, Portugal. The SWAT model was used to relate sustainable agricultural practices, agricultural yields and N-NO3 water pollution deliveries. Results show that crop yields as well as N-NO3 exportation rates decrease with reductions in N-application rates and single N-application methods lead to lower crop yields and higher N-NO3 exportation rates as compared to split and slow-release N-application methods.

    This book explores the microsensing technologies and systems now available to monitor the quality of air and water within the urban environment and examines their role in the creation of sustainable cities against the background of the challenges posed by rapid urbanization. The opening section addresses the theoretical and conceptual background of microsensing networks. The coverage includes detailed description of microsensors, supported by design-specific equations, and clear explanation of the ways in which devices that harvest energy from ambient sources can detect and quantify pollution. The practical application of such systems in addressing environmental impacts within cities and in sustainable urban planning is then discussed with the aid of case studies in developing countries. The book will be of interest to all who wish to understand the benefits of microsensing networks in promoting sustainable cities through better delivery of information on health hazards and improved provision of data to envir...

    Uwasu, Michinori; Shimoda, Yoshiyuki

    As global threats such as climate change and economic crisis have been emerging, the demand for the establishment of integrated disciplinary education programs is increasing. The Research Institute for Sustainability Science (RISS) at Osaka University started a new program on sustainability in October 2007. The RISS program addresses the ways to utilize knowledge effectively to understand the dynamic interactions between nature and human society. This paper first overviews the RISS Program for Sustainability Science. The paper then discusses the main problems as well as attempts and efforts to challenge those issues. Although issues including institutional barriers and faculty development yet remain in promoting integrated education, the RISS program functions as a platform to disseminate the idea of sustainability science across the university.

    Community-based interventions have been found to effectively increase the implementation of alcohol management practices and reduce excessive alcohol use and alcohol-related harm at sports clubs. However, once implementation support ceases there may be a reduction in such intervention effects. Thus, ongoing contribution to improving the health of the community is diminished; sustaining practice implementation is a key determinant to address this. One possible solution to the strategic and logistical challenges of sustainability involves the use of the web. The primary aim of this study is to assess the effectiveness of a web-based programme in sustaining the implementation of alcohol management practices by community football clubs. The secondary aim is to assess the effectiveness of the programme in preventing excessive alcohol consumption and alcohol-related harm among members of community football clubs. The study will employ a repeat randomised controlled trial design and be conducted in regional and metropolitan areas within two states of Australia. Community level football clubs who are currently accredited with an existing alcohol management programme ('Good Sports') and implementing at least 10 of the 13 core alcohol management practices (eg, not serving alcohol to sustainability programme or a 'minimal contact' programme. The primary outcome measures are the proportion of football clubs implementing ≥10 of the 13 required alcohol management practices and the mean number of those practices being implemented at 3-year follow-up. Secondary outcomes include: the proportion of club members who report risky drinking at their club, the Alcohol Use Disorder Identification Test (AUDIT) score and mean AUDIT score of club members. Outcome data will be collected via observation at the club during a 1-day visit to a home game, conducted by trained research assistants at baseline and follow-up. The study was approved by The University of Newcastle Human Research

    Study Goals: It is known that the manifold limitations of oral and practical examinations can be improved by specific training. With the help of an online survey, our present study analyzes the effects that can be achieved by the training conducted at the University of Ulm for examiners in the final medical examination, the long-lasting impact of the training, and differences among participant subgroups. Method: All 367 participants in the training at Ulm (2007- 2012) were contacted via email. Sixty-three persons responded to the survey that included 28 items concerning demographic data, effectiveness, and sustainability. Results: Six main effects of the training were identified (meaning effects rated with a grade of 1 or 2 on a 6-point scale by two thirds of the participants, with 1=“applicable” and 6=“not applicable”; cumulated percentage of answers of 1 or 2 in parentheses): Conscious handling of strengths and weaknesses of oral examinations (71%), Knowledge of factors contributing to the reliability of oral/practical examinations (76%), Knowledge of factors contributing to the validity of oral/practical examinations (75%), Improvement of competence in task construction (68%), Improvement of competence in respect to examination formalities (75%), Implementation of the concept of “structured oral examinations” (a priori planning of examination subjects, tasks, levels of expectation and grading criteria) (86%). The responses of participants trained more than two years ago were not significantly different from the answers given by recently trained persons. This is an argument for the sustainability of the training effects. Furthermore, participants without relevant prior experience in oral/practical examinations profited significantly more from the trainings, especially in the areas of stress reduction, confidence in grading, and competence in critical discrimination of grading. Conclusion: The positive and sustained effects of the examiner training

  5. Applying New Technologies to Transform Blueberry Harvesting

    Full Text Available The growth of the blueberry industry in the past three decades has been remarkably robust. However, a labor shortage for hand harvesting, increasingly higher labor costs, and low harvest efficiencies are becoming bottlenecks for sustainable development of the fresh market blueberry production. In this study, we evaluated semi-mechanical harvesting systems consisting of a harvest-aid platform with soft fruit catching surfaces that collected the fruit detached by portable, hand-held, pneumatic shakers. The softer fruit catching surfaces were not glued to the hard sub-surfaces of the harvest-aid platform, but suspended over them. Also, the ergonomic aspect of operating powered harvesting equipment was determined. The pneumatic shakers removed 3.5 to 15 times more fruit (g/min than by hand. Soft fruit catching surfaces reduced impact force and bruise damage. Fruit firmness was higher in fruit harvested by hand compared to that by pneumatic shakers in some cultivars. The bruise area was less than 8% in fruit harvested by hand and with semi-mechanical harvesting system. The percentage of blue, packable fruit harvested by pneumatic shakers comprised as much as 90% of the total, but less than that of hand-harvested fruit. The ergonomic analysis by electromyography showed that muscle strain in the back, shoulders, and forearms was low in workers operating the light-weight, pneumatic shakers that were tethered to the platform with a tool balancer. The new harvesting method can reduce the labor requirement to about 100 hour/hectare/year and help to mitigate the rising labor cost and shortage of workers for harvesting fresh-market quality blueberries.

  6. Criteria for sustainable fisheries on juveniles illustrated for Mediterranean hake: control the juvenile harvest, and safeguard spawning refugia to rebuild population fecundity

    Directory of Open Access Journals (Sweden)

    John F. Caddy

    2015-09-01

    Full Text Available The paper provides a broad overview of issues relevant to management of fisheries for juvenile fish in contrast to the many stock assessments following Beverton and Holt’s (1957 approach for rational exploitation of mature fishes. A perspective on assessing these fisheries is illustrated for juvenile European hake, Merluccius merluccius, in the northwestern Mediterranean. Here, a constant natural mortality (M assumption is incorrect, as is the assumption that high fecundities are necessarily adequate for stock replacement. The high Ms-at-age for juveniles generated by the reciprocal model are shown to be a logical counterpart to the high fecundity of hake. Charnov’s criterion of intergenerational reproductive replacement is used to test for a sustainable population, analogous to a limit reference point warning of the dangers of overfishing beyond population replacement. Once peak mortality rates of age 2 hake exceed F(2=1.1-1.2, which is currently the case, reproductive replacement may be at risk. Adult exploitation by inshore trawls is low, and maturing hake surviving the fine-mesh trawl fishery migrate offshore with a reduced vulnerability to fine-mesh gears. Early research suggested that rough bottom near the shelf edge once formed a refugium protecting offshore spawners from trawling, and led to abundant recruitment of juveniles nearer shore. It may not do so if offshore fishing effort by reinforced bottom trawls, gill nets and longlines is uncontrolled. Restoring offshore refugia to protect spawners and controlling peak fishing mortality of juveniles would be a precautionary strategy aimed at restoring previous levels of recruitment to the small-mesh trawl fishery.

    Ocean wave associated energy is huge, but it has little use toward world energy. Although such blue energy is capable of meeting all of our energy needs, there is no effective way to harvest it due to its low frequency and irregular amplitude, which may restrict the application of traditional power generators. In this work, we report a hybrid nanogenerator that consists of a spiral-interdigitated-electrode triboelectric nanogenerator (S-TENG) and a wrap-around electromagnetic generator (W-EMG) for harvesting ocean energy. In this design, the S-TENG can be fully isolated from the external environment through packaging and indirectly driven by the noncontact attractive forces between pairs of magnets, and W-EMG can be easily hybridized. Notably, the hybrid nanogenerator could generate electricity under either rotation mode or fluctuation mode to collect energy in ocean tide, current, and wave energy due to the unique structural design. In addition, the characteristics and advantages of outputs indicate that the S-TENG is irreplaceable for harvesting low rotation speeds (energy, which fits the frequency range for most of the water wave based blue energy, while W-EMG is able to produce larger output at high frequencies (>10 Hz). The complementary output can be maximized and hybridized for harvesting energy in a broad frequency range. Finally, a single hybrid nanogenerator unit was demonstrated to harvest blue energy as a practical power source to drive several LEDs under different simulated water wave conditions. We also proposed a blue energy harvesting system floating on the ocean surface that could simultaneously harvest wind, solar, and wave energy. The proposed hybrid nanogenerator renders an effective and sustainable progress in practical applications of the hybrid nanogenerator toward harvesting water wave energy offered by nature.

    Deliberation, dialogue and systematic learning are now considered attributes of good practice for organizations seeking to advance sustainability. Yet we do not know whether organizations that span spatial scales and governance responsibilities can establish effective communities of practice to facilitate learning and action. The purpose of this paper is to generate a framework that specifies actions and processes of a community of practice designed to instill collective learning and action strategies across a multi-level, multi-partner network. The framework is then used to describe and analyze a partnership among practitioners of Canada's 16 UNESCO biosphere reserves, and additional researchers and government representatives from across Canada. The framework is a cycle of seven action steps, beginning and ending with reflecting on and evaluating present practice. It is supported by seven characteristics of collaborative environmental management that are used to gauge the success of the partnership. Our results show that the partnership successfully built trust, established shared norms and common interest, created incentives to participate, generated value in information sharing and willingness to engage, demonstrated effective flow of information, and provided leadership and facilitation. Key to success was the presence of a multi-lingual facilitator who could bridge cultural differences across regions and academia-practitioner expectations. The project succeeded in establishing common goals, setting mutual expectations and building relations of trust and respect, and co-creating knowledge. It is too soon to determine whether changes in practices that support sustainability will be maintained over the long term and without the help of an outside facilitator.

    Best practice guidelines are a tool for narrowing research-to-practice gaps and improving care outcomes. There is some empirical understanding of guideline implementation in nursing settings, yet there has been almost no consideration of the longer-term sustainability of guideline-based practice improvements. Many healthcare innovations are not sustained, underscoring the need for knowledge about how to promote their survival. To understand how a nursing best practice guidelines program was sustained on acute healthcare center nursing units. We undertook a qualitative descriptive case study of an organization-wide nursing best practice guidelines program with four embedded nursing unit subcases. The setting was a large, tertiary/quaternary urban health center in Canada. The nursing department initiated a program to enhance patient safety through the implementation of three guidelines: falls prevention, pressure ulcer prevention, and pain management. We selected four inpatient unit subcases that had differing levels of program sustainability at an average of almost seven years post initial program implementation. Data sources included 39 key informant interviews with nursing leaders/administrators and frontline nurses; site visits; and program-related documents. Data collection and content analysis were guided by a framework for the sustainability of healthcare innovations. Program sustainability was characterized by three elements: benefits, routinization, and development. Seven key factors most accounted for the differences in the level of program sustainability between subcases. These factors were: perceptions of advantages, collaboration, accountability, staffing, linked levels of leadership, attributes of formal unit leadership, and leaders' use of sustainability activities.

    The potential use of rainwater harvesting in conjunction with miscellaneous water supplies and a rooftop garden with rainwater harvesting facility for temperature reduction have been evaluated in this study for Hong Kong. Various water applications such as toilet flushing and areal climate controls have been systematically considered depending on the availability of seawater toilet flushing using the Geographic Information System (GIS). For water supplies, the district Area Precipitation per Demand Ratio (APDR) has been calculated to quantify the rainwater utilization potential of each administrative district in Hong Kong. Districts with freshwater toilet flushing prove to have higher potential for rainwater harvest and utilization compared to the areas with seawater toilet flushing. Furthermore, the effectiveness of using rainwater harvesting for miscellaneous water supplies in Hong Kong and Tokyo has been analyzed and compared; this revives serious consideration of diurnal and seasonal patterns of rainfall in applying such technology. In terms of the cooling effect, the implementation of a rooftop rainwater harvesting garden has been evaluated using the ENVI-met model. Our results show that a temperature drop of 1.3 °C has been observed due to the rainwater layer in the rain garden. This study provides valuable insight into the applicability of the rainwater harvesting for sustainable water management practice in a highly urbanized city. Copyright © 2015 Elsevier Ltd.

    Biazin, Birhanu; Sterk, Geert; Temesgen, Melesse; Abdulkedir, Abdu; Stroosnijder, Leo

    Agricultural water scarcity in the predominantly rainfed agricultural system of sub-Saharan Africa (SSA) is more related to the variability of rainfall and excessive non-productive losses, than the total annual precipitation in the growing season. Less than 15% of the terrestrial precipitation takes the form of productive ‘green’ transpiration. Hence, rainwater harvesting and management (RWHM) technologies hold a significant potential for improving rainwater-use efficiency and sustaining rainfed agriculture in the region. This paper outlines the various RWHM techniques being practiced in SSA, and reviews recent research results on the performance of selected practices. So far, micro-catchment and in situ rainwater harvesting techniques are more common than rainwater irrigation techniques from macro-catchment systems. Depending on rainfall patterns and local soil characteristics, appropriate application of in situ and micro-catchment techniques could improve the soil water content of the rooting zone by up to 30%. Up to sixfold crop yields have been obtained through combinations of rainwater harvesting and fertiliser use, as compared to traditional practices. Supplemental irrigation of rainfed agriculture through rainwater harvesting not only reduces the risk of total crop failure due to dry spells, but also substantially improves water and crop productivity. Depending on the type of crop and the seasonal rainfall pattern, the application of RWHM techniques makes net profits more possible, compared to the meagre profit or net loss of existing systems. Implementation of rainwater harvesting may allow cereal-based smallholder farmers to shift to diversified crops, hence improving household food security, dietary status, and economic return. The much needed green revolution and adaptations to climate change in SSA should blend rainwater harvesting ideals with agronomic principles. More efforts are needed to improve the indigenous practices, and to disseminate best

  12. Withholding and withdrawing life-sustaining treatment: criminal responsibility for established medical practice?

    Science.gov (United States)

    White, Ben; Willmott, Lindy; Allen, John

    2010-05-01

    The law recognises the right of a competent adult to refuse medical treatment even if this will lead to death. Guardianship and other legislation also facilitates the making of decisions to withhold or withdraw life-sustaining treatment in certain circumstances. Despite this apparent endorsement that such decisions can be lawful, doubts have been raised in Queensland about whether decisions to withhold or withdraw life-sustaining treatment would contravene the criminal law, and particularly the duty imposed by the Criminal Code (Qld) to provide the "necessaries of life". This article considers this tension in the law and examines various arguments that might allow for such decisions to be made lawfully. It ultimately concludes, however, that criminal responsibility may still arise and so reform is needed.

    In recent decades, evidence-based practices (EBPs) have been broadly promoted in community behavioural health systems in the United States of America, yet reported EBP penetration rates remain low. Determining how to systematically sustain EBPs in complex, multi-level service systems has important implications for public health. This study examined factors impacting the sustainability of parent-child interaction therapy (PCIT) in large-scale initiatives in order to identify potential predictors of sustainment. A mixed-methods approach to data collection was used. Qualitative interviews and quantitative surveys examining sustainability processes and outcomes were completed by participants from 12 large-scale initiatives. Sustainment strategies fell into nine categories, including infrastructure, training, marketing, integration and building partnerships. Strategies involving integration of PCIT into existing practices and quality monitoring predicted sustainment, while financing also emerged as a key factor. The reported factors and strategies impacting sustainability varied across initiatives; however, integration into existing practices, monitoring quality and financing appear central to high levels of sustainability of PCIT in community-based systems. More detailed examination of the progression of specific activities related to these strategies may aide in identifying priorities to include in strategic planning of future large-scale initiatives.

    In this article we discuss whether the French eco-neighbourhood policy tool may be considered as an original experimentation in sustainable urban planning. From scientific literature across a number of countries and especially in European context, we present what kind of policies may achieve eco-neighbourhoods. Then we present what the French framework is, and what tools to promote and elaborate eco-neighbourhoods there are in France. Thirdly, in fact, both French policies, national and local, concerning eco-neighbourhood projects, seem to integrate means of assessing urban projects and this assessment achieves a kind of certification. While the Ministry in charge of Urban Planning has developed the national EcoQuartier ("EcoNeighbourhood" in English) certification, the City of Paris and other local authorities have designed similar tools, which integrate a large number of parameters dealing with urban sustainability and which are designed to evolve over time. Finally, we discuss whether the French tool is really original and whether it prefigures new practices in the field of sustainable urban development. Copyright © 2016 Elsevier Ltd.

    2017-02-01

    Current asthma guidelines recommend a control-based approach to management that involves assessment of impairment and risk followed by implementation of treatment strategies individualized according to the patient's needs and preferences. The fact that many patients still experience severe symptoms that negatively affect quality of life suggests that asthma control remains an objective to be achieved. Tools are available to help patients (and families) manage the day-to-day and short-term variability in asthma symptoms; however, when and how to implement a sustained step-up in therapy is less clear. The Asthma Yardstick is a comprehensive update on how to conduct a sustained step-up in asthma therapy for the patient with not well-controlled or poorly controlled asthma. Patient profiles and step-up strategies are based on current guidelines, newer data, and the authors' combined clinical experience and are intended to provide a practical and clinically meaningful guide toward the goal of well-controlled asthma for every patient. The development of this tool comes in response to the continued need to proactively address the sustained loss of asthma control at all levels of severity.

    The outcomes based emphasis in nursing and health care delivery requires identification of best available evidence in order to produce quality, safe, and effective patient care. Finding, critiquing, and ultimately implementing the best available evidence for practice is a formidable task for many clinical nurses. Development and implementation of a nursing journal club (NJC) became one organization's successful attempt to help clinical nurses better understand and use best available evidence in actual practice. The process and structure for the NJC evolved from an additional activity scheduled outside of work to a fully established endeavor of Nursing Research and Evidence Based Practice Council (NR&EBP). The Nursing Professional Practice Model was foundational to establishing the NJC as a formal component within the NR&EBP Council shared governance structure. Efforts to embed the NJC included taking advantage of resources available at an academic medical center and incorporating them into the council structure. Successful outcomes of the NJC include a quarterly schedule, with topics selected in advance that are based on nursing department as well as organizational driven goals and initiatives. The structure and process in place has eliminated frequently mentioned deterrents to evidence based practice such as not enough time, lack of knowledge, or no immediate application to practice. Incorporating the NJC as a component of NR&EBP Council has provided clinical nurses time away from clinical care that supports scholarship for nursing practice. Committed leadership and garnering of available resources have been key factors for success. Copyright © 2016 Elsevier Inc. All rights reserved.

    2017-02-01

    In the Horizon 2020 work programme 2016-17 it is stated that in 2010, 71% of European farm managers were operating on the basis of practical experience only. Education levels greatly vary depending on country, farm managers' age and gender, or farm structures, and this can hamper innovation. Transition towards a more sustainable agriculture requires a renewal and strengthening of the technical skills of all the actors involved and - as a consequence - of the educational system. The EU Directive on the sustainable use of pesticides (EU, 128/2009/EC) requires European Member States to develop training activities targeting occupational exposure to pesticides. The objective of this study is to develop new training tools for operators, addressing the new legal requirements and taking into account what is already available. For this reason, the outcomes of different European and national research projects developed by the Opera Research Centre were used, involving stakeholders in the decision making process, but also considering the real behaviours and perceptions of the final users. As a result, an e-learning tool able to build personalized training programmes, by collecting and integrating existing training material on Plant Protection Products use was developed, together with an e-learning course, with the aim to help operators, advisors and distributors to get prepared for their national certificate test. This work highlights the opportunity to create long-term added value through enhanced collaboration between educators and researchers, and identifies a common set of priorities that has to be taken into account in order to nudge the changes required to achieve a more sustainable use of pesticide and, more in general, sustainable development.

  5. Planning policy, sustainability and housebuilder practices: The move into (and out of?) the redevelopment of previously developed land.

    Karadimitriou, Nikos

    2013-05-01

    This paper explores the transformations of the housebuilding industry under the policy requirement to build on previously developed land (PDL). This requirement was a key lever in promoting the sustainable urban development agenda of UK governments from the early 1990s to 2010 and has survived albeit somewhat relaxed and permutated in the latest National Planning Policy Framework (NPPF). The paper therefore looks at the way in which the policy push towards densification and mixed use affected housebuilders' business strategy and practices and their ability to cope with the 2007 downturn of the housing market and its aftermath. It also points out the eventual feedback of some of these practices into planning policy. Following the gradual shift of British urban policy focus towards sustainability which started in the early 1990s, new configurations of actors, new skills, strategies and approaches to managing risk emerged in property development and housebuilding. There were at least two ways in which housebuilders could have responded to the requirements of developing long term mixed use high density projects on PDL. One way was to develop new products and to employ practices and combinations of practices involving phasing, a flexible approach to planning applications and innovative production methods. Alternatively, they could approach PDL development as a temporary turn of policy or view mixed use high density schemes as a niche market to be explored without drastically overhauling the business model of the entire firm. These transformations of the UK housebuilding sector were unfolding during a long period of buoyancy in the housing market which came to an end in 2007. Very little is known both about how housebuilder strategies and production practices evolved during the boom years as well as about how these firms coped with the effects of the 2007 market downturn. The paper draws on published data (company annual reports, government statistics) and primary

    Healthcare professionals working in the community do not always prescribe oral nutritional supplements (ONS) according to best practice guidelines for the management of malnutrition. The present study aimed to determine the impact of a community dietetics intervention on ONS prescribing practices and expenditure 1 year later. The intervention involved general practitioners (GPs), practice nurses, nurses in local nursing homes and community nurses. It comprised an education programme together with the provision of a new community dietetics service. Changes in health care professionals' nutrition care practices were determined by examining community dietetics records. ONS prescribing volume and expenditure on ONS were assessed using data from the Primary Care Reimbursement Service of the Irish Health Service Executive. Seven out of 10 principal GPs participated in the nutrition education programme. One year later, screening for malnutrition risk was better, dietary advice was provided more often, referral to the community dietetics service improved and ONS were prescribed for a greater proportion of patients at 'high risk' of malnutrition than before (88% versus 37%; P dietetics intervention improved ONS prescribing practices by GPs and nurses, in accordance with best practice guidelines, without increasing expenditure on ONS during the year after intervention. © 2011 The Authors.

    To provide growing population with sufficient food, greenhouse vegetable production has expanded rapidly in recent years in China and sustainability of its farming practices is a major concern. Therefore, this study assessed the sustainability of greenhouse vegetable farming practices from environmental, economic, and socio-institutional perspectives in China based on selected indicators. The empirical data were collected through a survey of 91 farm households from six typical greenhouse vegetable production bases and analysis of environmental material samples. The results showed that heavy fertilization in greenhouse vegetable bases of China resulted in an accumulation of N, P, Cd, Cu, Pb, and Zn in soil, nutrient eutrophication in irrigation water, and high Cd in some leaf vegetables cultivated in acidic soil. Economic factors including decreased crop yield in conventional farming bases, limited and site-dependent farmers' income, and lack of complete implementation of subsidy policies contributed a lot to adoption of heavy fertilization by farmers. Also, socio-institutional factors such as lack of unified management of agricultural supplies in the bases operated in cooperative and small family business models and low agricultural extension service efficiency intensified the unreasonable fertilization. The selection of cultivated vegetables was mainly based on farmers' own experience rather than site-dependent soil conditions. Thus, for sustainable development of greenhouse vegetable production systems in China, there are two key aspects. First, it is imperative to reduce environmental pollution and subsequent health risks through integrated nutrient management and the planting strategy of selected low metal accumulation vegetable species especially in acidic soil. Second, a conversion of cooperative and small family business models of greenhouse vegetable bases to enterprises should be extensively advocated in future for the unified agricultural supplies

  11. Sustaining reductions in postoperative nausea and vomiting after evidence-based practice initiative: A success story

    Directory of Open Access Journals (Sweden)

    Christopher A Smith

    2017-07-01

    Full Text Available Background: Postoperative nausea and vomiting (PONV remains a signifi cant problem in the surgical population. Many researchers have demonstrated signifi cant reductions in institutional PONV when risk screening and antiemetic prophylaxis protocols are implemented. These protocols have not been universally adopted. Our adoption and implementation led to signifi cant reductions in PONV. The challenge is to sustain these reductions over time. Methods: A retrospective cohort chart review of consecutive surgical patients (n = 1002 during the period encompassing October through November of 2016, the sustainability group (G16. Descriptive statistics were used to compare G16 with the implementation group (G14 in regard to demographic data, and Z-score and Chi-square (χ2 statistics were utilized to determine levels of signifi cance. Correlations were calculated to determine levels of compliance to the protocol and the incidence of PONV. Results: A significant (P = 0.0007 reduction in PONV incidence was identified as 8.5% (85/1002 in G16 compared to 13.4% (134/997 achieved in G14. Overall compliance with the targeted prophylaxis protocol was 87.2% (G16, 874/1002, a significant (P = 0.0001 improvement compared to 79% (G14, 788/997. A 61.1% (11/18 incidence of PONV in laparoscopic gastric bypass patients was identifi ed in the G16 group. Conclusions: Initial reductions in PONV were not only sustained but significantly improved. Preoperative risk assessment for PONV, risk stratification, and fidelity to anti-emetic prophylaxis protocols reduce the incidence of PONV in the post-anesthesia care unit. High-risk patients require three or more interventions to obtain acceptable reductions in PONV. Laparoscopic gastric bypass patients remain a high-risk group requiring aggressive multimodal prophylaxis beyond their Apfel simplifi ed risk score.

    A school-located mass vaccination program can enable rapid vaccination of a large number of students while minimizing disruption of their school activities. During 3 consecutive influenza seasons beginning in 2005, the Knox County Health Department conducted school-located mass vaccination clinics using live attenuated influenza vaccine. Overall, the proportion of elementary schoolchildren vaccinated with live attenuated influenza vaccine exceeded 40% each year. We describe key lessons learned in clinic operations, including obtaining informed consent, defining the organizational structure and roles, preparing the school, staffing, training, supplies, vaccine management, team communication, and data management. We conclude by discussing program costs and sustainability.

  13. Impact of Euro-Canadian agrarian practices: in search of sustainable import-substitution strategies to enhance food security in subarctic Ontario, Canada.

    Spiegelaar, Nicole F; Tsuji, Leonard J S

    2013-01-01

    In Canada, food insecurity exists among Aboriginal (Inuit, Metis and First Nations) people living in remote northern communities, in part, because of their reliance on the industrialized, import-based food system. Local food production as a substitute to imports would be an adaptive response, but enhancement of food security via food localization requires reflection on previous failings of conventional agricultural strategies so that informed decisions can be made. In light of potential reintroduction of local food production in remote First Nations communities, we investigated the cultural, social and ecological effects of a 20th century, Euro-Canadian agrarian settlement on the food system of a subarctic First Nation; this will act as the first step in developing a more sustainable local food program and enhancing food security in this community. To investigate the socio-cultural impacts of the Euro-Canadian agrarian initiative on the food system of Fort Albany First Nation, purposive, semi-directive interviews were conducted with elders and other knowledgeable community members. Interview data were placed into themes using inductive analyses. To determine the biophysical impact of the agrarian initiative, soil samples were taken from one site within the cultivated area and from one site in an undisturbed forest area. Soil properties associated with agricultural use and productivity were assessed. To compare the means of a given soil property between the sites, one-tailed t-tests were employed. Vegetative analysis was conducted in both sites to assess disturbance. According to the interviewees, prior to the agrarian initiative, First Nation families harvested wild game and fish, and gathered berries as well as other forms of vegetation for sustenance. With the introduction of the residential school and agrarian initiative, traditional food practices were deemed inadequate, families were forced to work and live in the settlement (becoming less reliant on

    Till now, herbicide seems to be a cost effective tool from an agronomic view point to control weeds. But long term efficacy and sustainability issues are the driving forces behind the reconsideration of herbicide dependent weed management strategy in rice. This demands reappearance of physical and cultural management options combined with judicious herbicide application in a more comprehensive and integrated way. Keeping those in mind, some agronomic tools along with different manual weeding and herbicides combinations were evaluated for their weed control efficacy in rice under aerobic soil conditions. Combination of competitive variety, higher seeding rate, and seed priming resulted in more competitive cropping system in favor of rice, which was reflected in lower weed pressure, higher weed control efficiency, and better yield. Most of the herbicides exhibited excellent weed control efficiency. Treatments comprising only herbicides required less cost involvement but produced higher net benefit. On the contrary, treatments comprising both herbicide and manual weeding required high cost involvement and thus produced lower net benefit. Therefore, adoption of competitive rice variety, higher seed rate, and seed priming along with spraying different early-postemergence herbicides in rotation at 10 days after seeding (DAS) followed by a manual weeding at 30 DAS may be recommended from sustainability view point.

    Adequate hand hygiene is often considered as the most effective method of reducing the rates of hospital-acquired infections, which are one of the major causes of increased cost, morbidity, and mortality in healthcare. Electronic monitoring technologies provide a promising direction for achieving sustainable hand hygiene improvement by introducing the elements of automated feedback and creating the possibility to automatically collect individual hand hygiene performance data. The results of the multiphase testing of an automated hand hygiene reminding and monitoring system installed in a complex continuing care setting are presented. The study included a baseline Phase 1, with the system performing automated data collection only, a preintervention Phase 2 with hand hygiene status indicator enabled, two intervention Phases 3 and 4 with the system generating hand hygiene reminding signals and periodic performance feedback sessions provided, and a postintervention Phase 5 with only hand hygiene status indicator enabled and no feedback sessions provided. A significant increase in hand hygiene performance observed during the first intervention Phase 3 was sustained over the second intervention Phase 4, with the postintervention phase also indicating higher hand hygiene activity rates compared with the preintervention and baseline phases. The overall trends observed during the multiphase testing, the factors affecting acceptability of the automated hand hygiene monitoring system, and various strategies of technology deployment are discussed.

    A growing population with increasing consumption of milk and dairy require more agricultural output in the coming years, which potentially competes with forests and other natural habitats. This issue is particularly salient in the tropics, where deforestation has traditionally generated cattle pastures and other commodity crops such as corn and soy. The purpose of this article is to review the concepts and discussion associated with reconciling food production and conservation, and in particular with regards to cattle production, including the concepts of land-sparing and land-sharing. We then present these concepts in the specific context of Colombia, where there are efforts to increase both cattle production and protect tropical forests, in order to discuss the potential for landscape planning for sustainable cattle production. We outline a national planning approach, which includes disaggregating the diverse cattle sector and production types, identifying biophysical, and economic opportunities and barriers for sustainable intensification in cattle ranching, and analyzing areas suitable for habitat restoration and conservation, in order to plan for both land-sparing and land-sharing strategies. This approach can be used in other contexts across the world where there is a need to incorporate cattle production into national goals for carbon sequestration and habitat restoration and conservation.

    Full Text Available Aim: Volume replacement with fillers is regularly performed with the use of diverse volumetric materials to correct different structures around the face, depending on the volume enhancement required and the thickness of the soft tissue envelope. Differential fat harvesting and posterior grafting is performed to place the correct fat parcel size for each target area, expanding the potential applications of fat. Methods: Sixty patients consecutively recruited on a first come basis undergone a facial fat grafting procedure, in private practice setting between March 2012 and October 2013. Fat grafting quantity and quality was predicted for each case. Differential harvesting was performed, with 2 fat parcels size. Processing was performed through washing. Fat infiltration was carried out through small cannulas or needles depending on the treated area. Outcomes were analysed both by the physicians and the patients at 7 days, 1 month, 3 months and 6 months through a perceived satisfaction questionnaire. Parameters considered were downtime or discomfort, skin benefits, volume restoration, reabsorption rate estimated and overall improvement. Results: Full facial differential fat grafting procedure lasted an average of 1.5-2.5 h. Average downtime was 3-4 days. Follow-up was performed to a minimum of 6 months. Both patient and physician overall satisfaction rates were mostly excellent. Adverse events like lumps or irregularities were not encountered. Conclusion: Differential fat harvesting and posterior grafting is a valid alternative, to expand the repertoire of fat use, allow a more homogeneous effect, reduce the potential complications, speed up the process, improve graft survival, and to enhance overall aesthetic outcome.

    coupling that exists between tanks, the village communities, and the natural landscape within which they are embedded. Preliminary results suggest that groundwater over-extraction is in many cases negatively impacting the ability of the rainwater harvesting ponds to provide a reliable water supply. In addition, while the social and economic benefits provided by these ponds reduce community vulnerability to variations in the region's yearly monsoons, there can be negative environmental impacts. Large-scale rainwater harvesting, similar to groundwater extraction, can change the overall water balance of a watershed, leading to a tradeoff of water availability between socioeconomic and ecosystem demands. Although traditional rainwater harvesting practices may appear to be more sustainable than the current high levels of groundwater pumping, the two practices carried out in tandem can increase water consumption even further, pushing the system closer to a threshold beyond which a profound crisis may loom.

    Understanding feedbacks between human and environmental health is critical for the millions who cope with recurrent illness and rely directly on natural resources for sustenance. Although studies have examined how environmental degradation exacerbates infectious disease, the effects of human health on our use of the environment remains unexplored. Human illness is often tacitly assumed to reduce human impacts on the environment. By this logic, ill people reduce the time and effort that they put into extractive livelihoods and, thereby, their impact on natural resources. We followed 303 households living on Lake Victoria, Kenya over four time points to examine how illness influenced fishing. Using fixed effect conditional logit models to control for individual-level and time-invariant factors, we analyzed the effect of illness on fishing effort and methods. Illness among individuals who listed fishing as their primary occupation affected their participation in fishing. However, among active fishers, we found limited evidence that illness reduced fishing effort. Instead, ill fishers shifted their fishing methods. When ill, fishers were more likely to use methods that were illegal, destructive, and concentrated in inshore areas but required less travel and energy. Ill fishers were also less likely to fish using legal methods that are physically demanding, require travel to deep waters, and are considered more sustainable. By altering the physical capacity and outlook of fishers, human illness shifted their effort, their engagement with natural resources, and the sustainability of their actions. These findings show a previously unexplored pathway through which poor human health may negatively impact the environment.

    Full Text Available The purpose of this paper is to analyze the sustainability report for the communication of Corporate Social Responsibility (CSR in a nonprofit organization. To this aim, an Italian case study is analyzed: the Fondazione Renato Piatti Onlus, a nonprofit organization of Social Utility. In the first part, we analyze the CSR for nonprofit organizations and the sustainability report (also called ‘social balance’. In the second part, we present evidence from the case study. The research is exploratory in nature when considering the connection of corporate social responsibility efforts to the nonprofit sector, a qualitative methodology was chosen over quantitative methods. Specifically, the case study was used to show what strategy a nonprofit organization can develop. Nowadays CSR strategies received a growing attention from both businesses and nonprofit organizations but also from the EU which forced large public-interest entities to present a social balance. For nonprofit organizations, applying social responsibility is not a voluntary issue. Nonprofit organizations have an ethical obligation to their stakeholder and to the public to conduct their activities with accountability and transparency. Scholars have increasingly been studying the impact of corporate social responsibility as a business strategy in for-profit companies. However, there is still lack of researches on how nonprofit organizations implement CSR into the strategy. As a consequence of the above remarks, a large part of nonprofit organizations fails to correctly implement a successful long term CSR strategy. The Fondazione Renato Piatti Onlus belongs to that group that has been able to incorporate social responsibility within the organization, then expanding its content into a social report drawn up in accordance with the guidelines of the Italian Agency for the Third Sector.

    Member States (MS) of the European Union have experience significant urban sprawl in the last 3 decades. The urban sprawl was driven mainly by internal (MS or EU) or external migration but also by EU policies (including funds and projects) and by changes in life style (e.g. moving away from cities; second homes). This presentation will aim at showing a number of EU wide analysis on: aging population, depopulation of some of the EU regions; agricultural production and scenarios projections of thereof. Various EU funded projects and programs have analyzed ways how future cities and how EU future land use could developed. Number of those solutions where further investigated with case studies/small scale implementations. However, in recent years the 2012 EU road map to resource efficiency and UN Sustainable Development Goals have called respectively for 'no net land take by 2050' and land neutrality. Thus, the process of implementing innovative solutions for land use has started and some of the cities and regions are well ahead in moving towards XXI century society. In order to streamline/share knowledge and steer EU wide discussion on this the European Commission in its road map to resource efficiency announced a Communication on land as a resource. This presentation will attempt to synthesize current discussion on the topic of 'land as a resource' and include examples of implemented innovative solutions for aging population, land recycling for urban developments and green spaces within the current EU policy context. Finally, some appreciation of the adopted UN Sustainable Development Goals regarding land and soil from the EU perspective will be given.

    At the Amazon estuary, the oldest logging frontier in the Amazon, no studies have comprehensively explored the potential long-term population and yield consequences of multiple timber harvests over time. Matrix population modeling is one way to simulate long-term impacts of tree harvests, but this approach has often ignored common impacts of tree harvests including incidental damage, changes in post-harvest demography, shifts in the distribution of merchantable trees, and shifts in stand composition. We designed a matrix-based forest management model that incorporates these harvest-related impacts so resulting simulations reflect forest stand dynamics under repeated timber harvests as well as the realities of local smallholder timber management systems. Using a wide range of values for management criteria (e.g., length of cutting cycle, minimum cut diameter), we projected the long-term population dynamics and yields of hundreds of timber management regimes in the Amazon estuary, where small-scale, unmechanized logging is an important economic activity. These results were then compared to find optimal stand-level and species-specific sustainable timber management (STM) regimes using a set of timber yield and population growth indicators. Prospects for STM in Amazonian tidal floodplain forests are better than for many other tropical forests. However, generally high stock recovery rates between harvests are due to the comparatively high projected mean annualized yields from fast-growing species that effectively counterbalance the projected yield declines from other species. For Amazonian tidal floodplain forests, national management guidelines provide neither the highest yields nor the highest sustained population growth for species under management. Our research shows that management guidelines specific to a region's ecological settings can be further refined to consider differences in species demographic responses to repeated harvests. In principle, such fine

    2016-02-01

    Emerging data management mandates in conjunction with cross-domain international interoperability are posing new challenges for researchers and repositories. Domain repositories are serving in this critical, growing role monitoring and leading data management standards and capability within their own repository and working on mappings between repositories internationally. Leading research institutions and companies will also be important as they develop and expand data curation efforts. This landscape poses a number of challenges for developing and ensuring the use of best practices in curating research data, enabling discovery, elevating quality across diverse repositories, and helping researchers collect and organize it through the full data life cycle. This multidimensional challenge will continue to grow in complexity. The American Geophysical Union (AGU) is developing two programs to help researchers and data repositories develop and elevate best practices and address these challenges. The goal is to provide tools for the researchers and repositories, whether domain, institutional, or other, that improve performance throughout the data lifecycle across the Earth and space science community. For scientists and researchers, AGU is developing courses around handling data that can lead toward a certification in geoscience data management. Course materials will cover metadata management and collection, data analysis, integration of data, and data presentation. The course topics are being finalized by the advisory board with the first one planned to be available later this year. AGU is also developing a program aimed at helping data repositories, large and small, domain-specific to general, assess and improve data management practices. AGU has partnered with the CMMI® Institute to adapt their Data Management Maturity (DMM)SM framework within the Earth and space sciences. A data management assessment using the DMMSM involves identifying accomplishments and

    Full Text Available The dairy sector in the Netherlands aims for a 30% increase in efficiency and 30% carbon dioxide emission reduction compared to the reference year of 1990, and a 20% share of renewable energy, all by the year 2020. Anaerobic Digestion (AD can play a substantial role in achieving these aims. However, results from this study indicate that the AD system is not fully optimized in combination with farming practices regarding sustainability. Therefore, the Industrial Symbiosis concept, combined with energy and environmental system analysis, Life Cycle Analysis and modeling is used to optimize a farm-scale AD system on four indicators of sustainability (i.e., energy efficiency, carbon footprint, environmental impacts and costs. Implemented in a theoretical case, where a cooperation of farms share biomass feedstocks, a symbiotic AD system can significantly lower external energy consumption by 72 to 92%, carbon footprint by 71 to 91%, environmental impacts by 68 to 89%, and yearly expenditures by 56 to 66% compared to a reference cooperation. The largest reductions and economic gains can be achieved when a surplus of manure is available for upgrading into organic fertilizer to replace fossil fertilizers. Applying the aforementioned symbiotic concept to the Dutch farming sector can help to achieve the stated goals indicated by the Dutch agricultural sector for the year 2020.

    Full Text Available An important goal of fisheries management is to ensure that fish stocks are harvested at sustainable levels of fishing pressure. However, the classical maximum sustainable yield theory and its derivatives have not worked for fisheries management. A number of mitigating measures have been suggested of which eco -labeling is one. An ecolabel on a fish product is a distinctive mark or statement indicating that it has been harvested in compliance with preset sustainability standards. This paper examines eco labeling in fisheries as the new strategy to achieve fisheries conservation and sustainability. It emphasizes the importance of fish as critical food resources and new approach to fisheries management through the use of certification programs. It considers the benefits and problems that may accrue from eco-certification of fish harvesting and trade practices in fisheries. This paper, attention is focused on examining the likely option for development of eco-labeling scheme in Nigeria. The paper concludes that the increase awareness amongst stakeholders of the potential role of eco-labeling in conservation and sustainability tools should be established.   Keywords: Fisheries management, fish, conservation, eco-certification

    Currently there are about 4300 weld points on the average steel vehicle. Errors and problems due to tip damage and wear can cause great losses due to production line downtime. Current industrial monitoring systems check the quality of the nugget after processing 15 cars average once every two weeks. The nuggets are examined off line using a destructive process, which takes approximately 10 days to complete causing a long delay in the production process. In this paper a simulation results using software package, SORPAS, will be presented to determined the sustainability factors in spot welding process including Voltage, Current, Force, Water cooling rates, Material thicknesses and usage. The experimental results of various spot welding processes will be investigated and reported. The correlation of experimental results shows that SORPAS simulations can be used as an off line measurement to reduce factory energy usage. This paper also provides an overview of electrode current selection and its variance over the lifetime of the electrode tip, and describes the proposed analysis system for the selection of welding parameters for the spot welding process, as the electrode tip wears.

    Fung, K. M.; Tai, A. P. K.; Yong, T.; Liu, X.

    2016-12-01

    Agriculture provides the majority of human food sources, but is also an important contributor to an array of environmental problems including air pollution. In China, 96% of ammonia emissions come from agricultural activities, and emitted ammonia contributes more than 20% of fine particulate matter (PM2.5) mass concentrations, with substantial ramification for human health and visibility. Sustainable farming practices that reduce ammonia emissions may therefore have the potential to secure both food production and environmental quality. Intercropping, as such a practice, allows different crops to grow on the same field simultaneously side-by-side. Studies show that it enhances crop yield due to mutualistic crop-crop interactions especially when one of the crops is a legume such as soybean. Below-ground nutrient competition promotes greater nitrogen fixation by soybean, which then induces a greater supply of soil nitrogen not only for soybean itself but also for the other non-nitrogen-fixing crop. To capture this co-benefit, the DNDC biogeochemical model is modified to include the interactive effects between intercropped soybean and maize. We conduct model experiments to compare the performance of a maize-soybean intercropping system and their respective monoculture system in different regions of China. We find that, with intercropping, maize yield can be maintained with only 64% of default fertilizer input, an extra batch of soybean production, and a 52% reduction in ammonia emission, which we calculate to be equivalent to a US$0.94 billion saving per year in terms of pollution-induced health costs. We further estimate the downstream effects on air quality in China using the GEOS-Chem chemical transport model. By reducing ammonia emissions according to the DNDC-simulated results, we find that if maize-soybean intercropping is practiced nationwide, concentrations of ammonium and nitrate in eastern China can be reduced by approximately 4.9% (0.63 μg m-3) and 6.8% (2

    investigating organic solar cell technology. In spring 2011, Nanotechnology launches a new section wholly dedicated to the coverage of new and stimulating research into energy sources based on nanoscale science and technology. There is at present considerable concern over how to fuel the planet in a sustainable manner with the increasingly energy-thirsty human population. Yet the Earth receives more solar energy in one hour than the world population consumes in one year [8]. No wonder research into photovoltaics and ways of increasing the efficiency with which this energy can be harnessed continues to hold so much fascination. References [1] Levin I and White C E 1949 J.

    Traditional full-time employment has evolved into various types of occupational situations, and, nowadays, new work organization strategies have been developed. Previously overlooked risk factors have emerged, such as traffic accidents while commuting or during work hours, poor work organization, and detrimental lifestyles (like alcohol and substance abuse, although recent statistics seem to show a declining trend for the latter). The global scenario shows greater attention to occupational risks, but also, to the reduced degree of protection. Moreover, the elevated costs, the unacceptably high fatal accident rates in some sectors, the complexity of the prevention systems, the lack of prevention training, the inadequate controls (despite the numerous independent supervisory bodies) and the obsolescence of certain precepts, call for a prompt review of the regulatory system. This is especially needed for general simplification, streamlining certification bodies and minimizing references to other provisions in the legislation that make it difficult for Italian and foreign workers to read and understand the rules "without legal interpreters". "New" occupational diseases and occupational risk factors have also been reported in addition to pollution. There are concerns for continued economic and social destabilization, unemployment, commuting, temporary and precarious contracts. All of these contribute to the lack of wellbeing in the working population. Thus, the timing, duration, and types of prevention training should be carefully assessed, making prevention more appealing by evaluating costs and benefits with a widespread use of indicators that make appropriate actions for health promotion "visible", thus encouraging awareness. Although reducing prevention is never justified, it should still be "sustainable" economically in order to avoid waste of resources. It is also essential to have laws which are easily and consistently interpreted and to work on the ethics of

    Full Text Available Million tons of waste glass is being generated annually all over the world. Once the glass becomes a waste it is disposed as landfills, which is unsustainable as this does not decompose in the environment. Glass is principally composed of silica. Use of milled (ground waste glass in concrete as partial replacement of cement could be an important step toward development of sustainable (environmentally friendly, energy-efficient and economical infrastructure systems. When waste glass is milled down to micro size particles, it is expected to undergo pozzolanic reactions with cement hydrates, forming secondary Calcium Silicate Hydrate (C–S–H. In this research chemical properties of both clear and colored glass were evaluated. Chemical analysis of glass and cement samples was determined using X-ray fluorescence (XRF technique and found minor differences in composition between clear and colored glasses. Flow and compressive strength tests on mortar and concrete were carried out by adding 0–25% ground glass in which water to binder (cement + glass ratio is kept the same for all replacement levels. With increase in glass addition mortar flow was slightly increased while a minor effect on concrete workability was noted. To evaluate the packing and pozzolanic effects, further tests were also conducted with same mix details and 1% super plasticizing admixture dose (by weight of cement and generally found an increase in compressive strength of mortars with admixture. As with mortar, concrete cube samples were prepared and tested for strength (until 1 year curing. The compressive strength test results indicated that recycled glass mortar and concrete gave better strength compared to control samples. A 20% replacement of cement with waste glass was found convincing considering cost and the environment.

    Energy harvesting for the purpose of powering low power electronic sensor systems has received explosive attention in the last few years. Most works using deterministic approaches focusing on using the piezoelectric effect to harvest ambient vibration energy have concentrated on cantilever beams at resonance using harmonic excitation. Here, using a stochastic approach, we focus on using a stack configuration and harvesting broadband vibration energy, a more practically available ambient source. It is assumed that the ambient base excitation is stationary Gaussian white noise, which has a constant power-spectral density across the frequency range considered. The mean power acquired from a piezoelectric vibration-based energy harvester subjected to random base excitation is derived using the theory of random vibrations. Two cases, namely the harvesting circuit with and without an inductor, have been considered. Exact closed-form expressions involving non-dimensional parameters of the electromechanical system have been given and illustrated using numerical examples.

    This article deals with the energy harvesting systems, especially the energy harvesting backpack, which appears as a convenient means for energy harvesting for mobile sensors power. Before starting the experiment, it was necessary to verify whether this energy will be sufficient to get acquainted with the human kinematics and analyze problematics itself. For this purpose there was used motion capture technology from Xsens. Measured data on the position of a particle moving man and back when walking, these data were then used for experimental realization of energy harvesting backpack and as input data to the simulation in Simulink, which brought us a comparison between theoretical assumptions and practical implementation. When measuring characteristics of energy harvesting system we have a problem with measurements on backpack solved when redoing of the hydraulic cylinder as a source of a suitable movement corresponding to the amplitude and frequency of human walk.

    Recent systems analysis studies at Oak Ridge National Laboratory (ORNL) have shown that sufficient information is available from previous research and development (R and D), industrial experience, and current studies to make rational decisions on a practical approach to a closed nuclear fuel cycle in the United States. These studies show that a near-term decision is needed to recycle used nuclear fuel (UNF) in the United States, to encourage public recognition that a practical solution to disposal of nuclear energy wastes, primarily UNF, is achievable, and to ensure a focus on essential near-term actions and future R and D. Recognition of the importance of time factors is essential, including the multi-decade time period required to implement industrial-scale fuel recycle at the capacity needed, and the effects of radioactive decay on proliferation resistance, recycling complexity, radioactive emissions, and high-level-waste storage, disposal form development, and eventual emplacement in a geologic repository. Analysis of time factors led to identification of the benefits of processing older fuel and an 'optimum decay storage time'. Further benefits of focused R and D can ensure more complete recycling of UNF components and minimize wastes requiring disposal. Analysis of recycling costs and nonproliferation requirements, which are often cited as reasons for delaying a decision to recycle, shows that (1) the differences in costs of nuclear energy with open or closed fuel cycles are insignificant and (2) nonproliferation requirements can be met by a combination of 'safeguards-by-design' co-location of back-end fuel cycle facilities, and applied engineered safeguards and monitoring. The study shows why different methods of separating and recycling used fuel components do not have a significant effect on nonproliferation requirements and can be selected on other bases, such as process efficiency, maturity, and cost-effectiveness. Finally, the study

    Noting the upstream positioning of sustainable food systems (SFS) to multiple global crises, the present review described examples of emerging and promising practices to support SFS-oriented education, practical training (PT) and continuing professional development (CPD) among trainees and public health practitioners (PHP). A secondary objective was to compile the evidence into practical considerations for educators, supervising practitioners and professional associations. A scoping review of the literature published between 2007 and 2017 was conducted in May 2017 using four databases: CINAHL, MEDLINE, Scopus and HSSA, along with bibliography hand-searching and expert consultation. Articles were screened for relevance and specificity by independent raters. Nineteen articles were included for analysis. Two-thirds of the articles related to dietitians and public health nutritionists. Emerging practices included curriculum-based considerations, incorporation of 'sustainability' within professional competencies and self-reflection related to SFS. Descriptions of SFS-related education, PT and CPD practices appeared largely in the literature from developed countries. Articles converged on the need for ecosystems, food systems and sustainability considerations within and across practice to support current and future practitioners. There is growing interest in SFS but guidance to support educators and preceptors is lacking. Updates to dietary guidelines to reflect issues of sustainability are a timely prompt to examine the education, training and development needs of trainees and PHP. Practical examples of emerging practices can empower PHP to promote SFS in all areas of practice. More research is needed to address identified gaps in the literature and to improve SFS-specific education, PT and CPD.

    As the role of 2YC (two-year colleges/community colleges) changes in the academic pipeline of higher education new practices and ideas to engage and retain students in the geosciences at the 2YC level need to be explored. 2YC typically have a student body composed of non-traditional students ranging from second career students, single parents, students with disabilities, seniors, and minorities. Currently, 2YCs serve 44% of all undergraduate students and 45% of all of all first time freshmen in the US. These statistics show the potential community colleges hold to encourage entering students to the STEM (Science Technology Engineering and Math) fields as a possible career choice. But the reality is the number of STEM degrees awarded at community colleges has not followed the same trends in student enrollment. Over the past four years El Paso Community College (EPCC) in conjunction with The University of Texas at El Paso (UTEP) has implemented several initiatives in our effort to increase the number of Geological Science majors at EPCC and to ensure a successful transition to UTEP. These efforts are aimed to decrease attrition rates of science majors by; articulating degree plans between institutions, introduce field-based research projects to allow hands on experience for students, develop a working relationship between students and university faculty, diversify geology courses offered at EPCC, and strengthening the educational-bridge between the geological science departments of EPCC and UTEP through the aid of federally funded programs. The success of the these efforts have been seen by; the increase in geology majors in our A.S. degree program, the number of degrees conferred at EPCC, the successful transition of students to UTEP, and graduation of students from UTEP with advanced degrees.

  15. Extending the scope of eco-labelling in the food industry to drive change beyond sustainable agriculture practices.

    New consumer awareness is shifting industry towards more sustainable practices, creating a virtuous cycle between producers and consumers enabled by eco-labelling. Eco-labelling informs consumers of specific characteristics of products and has been used to market greener products. Eco-labelling in the food industry has yet been mostly focused on promoting organic farming, limiting the scope to the agricultural stage of the supply chain, while carbon labelling informs on the carbon footprint throughout the life cycle of the product. These labelling strategies help value products in the eyes of the consumer. Because of this, decision makers are motivated to adopt more sustainable models. In the food industry, this has led to important environmental impact improvements at the agricultural stage, while most other stages in the Food Supply Chain (FSC) have continued to be designed inefficiently. The objective of this work is to define a framework showing how carbon labelling can be integrated into the design process of the FSC. For this purpose, the concept of Green Supply Chain Network Design (GSCND) focusing on the strategic decision making for location and allocation of resources and production capacity is developed considering operational, financial and environmental (CO 2 emissions) issues along key stages in the product life cycle. A multi-objective optimization strategy implemented by use of a genetic algorithm is applied to a case study on orange juice production. The results show that the consideration of CO 2 emission minimization as an objective function during the GSCND process together with techno-economic criteria produces improved FSC environmental performance compared to both organic and conventional orange juice production. Typical results thus highlight the importance that carbon emissions optimization and labelling may have to improve FSC beyond organic labelling. Finally, CO 2 emission-oriented labelling could be an important tool to improve the

    Global competition in the automotive industry has encouraged companies to implement quality management practices in all managerial aspects to ensure customer satisfaction in products and reduce costs. Therefore, guaranteeing only product quality is insufficient without considering product sustainability, which involves economic, environment, and social elements. Companies that meet both objectives gain advantages in the modern business environment. This study addresses the issues regarding product quality and sustainability in small and medium-sized enterprises in the Malaysian automotive industry. A research was carried out in 91 SMEs automotive suppliers in throughout Malaysia. The analyzed using SPSS ver.23 has been proposed in correlation study. Specifically, this study investigates the relationship between quality management practices and organizational performance as well as the mediating effect of sustainable product development on this relationship.

    2015-04-01

    Western Siberia is of global significance in terms of agricultural production, carbon sequestration and biodiversity preservation. Abandonment of arable land and changes in the use of permanent grasslands were triggered by the dissolution of the Soviet Union in and the following collapse of the state farm system. The peatlands, forests and steppe soils of Western Siberia are one of the most important carbon sinks worldwide. These carbon stocks are, if deteriorated, an important source of radiative forcing even in comparison to anthropogenic emissions. This situation is aggravated by recent and future developments in agricultural land use in the southern part of Western Siberia, in particular in Tyumen province. The increase of drought risk caused by climate change will led to more challenges in these water-limited agricultural production systems. The German-Russian interdisciplinary research project "SASCHA" aims to provide sustainable land management practices to cope with these far-reaching changes for Tyumen province. In particular, on farm scale agricultural strategies are being developed for increased efficiencies in crop production systems. Therefore a 3-factorial field trial with different tillage and seeding operations was installed with spring wheat on 10 ha under practical conditions in 2013. Within all combinations of tillage (no-till/conventional), seed rate (usual/reduced) and seed depth (usual/shallower) various soil parameters as well as plant development and yield components were intensively monitored during the growing seasons. Results after 2-years show significant impacts of the tillage operation on soil moisture and soil temperature. Also a higher trend in nitrogen mineralization could be observed without tillage. Plant development in terms of phenological growth stages took place simultaneously in all variants. Under no-till regime we measured slightly higher grain yields and significant advantages in protein yields. In conjunction with
