Carbon Capture Clustering: the Case for Coordinated Approaches to Address Freshwater Use Concerns

Carbon capture and storage (CCS) will be a key technology for reducing emissions from fossil-fuelled electricity generation. The UK is developing demonstration plants and UK Government strategy proposes the clustering of CCS facilities, having identified significant cost-savings from shared pipeline infrastructure. However, cooling water use from CCS power plants are almost double those of conventional plants. There are concerns about the volumes of freshwater used and vulnerability to low river flows, particularly in areas identified for CCS clusters. Two innovative approaches may reduce water use in CCS clusters by exploiting synergies with other infrastructures; district heating and municipal wastewater. Our analysis indicates that cooling water reductions from district heating may be feasible in the northwest, but less likely in Yorkshire. We also find that across the UK there are numerous, sufficiently large wastewater treatment plants capable of providing alternative cooling water sources for large power plants. Feasibility of these promising options will be highly contextual, require detailed analysis and may face economic and regulatory barriers. Historically, ad-hoc development of energy infrastructure has struggled to exploit such synergies, but may now be facilitated by the clustering of CCS facilities

ARE WINE CO-OPERATIVES CREATING VALUE?

This article examines the introduction of Economic Value Added (EVA) as a performance measure that South African wine co-operatives can use to determine whether value has been created for members. A detailed explanation of EVA is given, and the components of EVA are calculated. The EVA's of a number of co-operatives have been calculated and analysed. Important trends have been identified. Recommendations have been made based on the conclusions drawn from these results. Finally, opportunities for potential improvement that could arise from using EVA as a performance measure in wine co-operatives are discussed.Agribusiness,

THE FINANCIAL PERFORMANCE OF FARMING CO-OPERATIVES: ECONOMIC VALUE ADDED VS TRADITIONAL MEASURES

The profitability measures have limitations for examining wealth creation. Economic Value Added (EVA) is being used by businesses to measure wealth creation. EVA has some advantages over other financial ratios because it fully accounts for the resources used by co-operatives and it includes both realized and unrealized capital gains in the calculation. This article examines the EVA metric for four years of co-operative financial data to determine if it provides additional information about wealth creation and profitability than do the other ratios.Agribusiness,

ARE WINE CO-OPS CREATING VALUE?

This article examines introducing Economic Value Added (EVA) as a performance measure for wine cooperatives in South Africa to determine whether member's value have been created. After a thorough explanation and calculation of the components of EVA, the EVA of a number of co-operatives were calculated and analyzed. Important trends were identified, conclusions drawn and recommendations made from these results. Finally, potential improvement opportunities resulting from using EVA as a performance measure in wine cooperatives are discussed.Agribusiness, Productivity Analysis,

ARE SOUTH AFRICAN CO-OPERATIVES CREATING VALUE

This article examines the use of Economic Value Added (EVA) as a performance measure that South African wine co-operatives can use to determine whether value has been created for members. A detailed explanation of EVA is given, and the components of EVA are calculated. The EVA's of a number of co-operatives have been calculated and analysed. In addition the EVA of specific types of co-operatives indicate that the fruit and vegetable sector is a constant value creator. It is clear that in order to create value, the rate of return on invested capital must be greater than the cost of capital. Certain co-operatives and types of co-operatives provided the blue print for this.economic value added, agricultural cooperatives, value, economic model, Agribusiness,

Smart Pricing: Linking Pricing Decisions with Operational Insights

The past decade has seen a virtual explosion of information about customers and their preferences. This information potentially allows companies to increase their revenues, in particular since modern technology enables price changes to be effected at minimal cost. At the same time, companies have taken major strides in understanding and managing the dynamics of the supply chain, both their internal operations and their relationships with supply chain partners. These two developments are narrowly intertwined. Pricing decisions have a direct effect on operations and visa versa. Yet, the systematic integration of operational and marketing insights is in an emerging stage, both in academia and in business practice. This article reviews a number of key linkages between pricing and operations. In particular, it highlights different drivers for dynamic pricing strategies. Through the discussion of key references and related software developments we aim to provide a snapshot into a rich and evolving field.supply chain management;inventory;capacity;dynamic pricing;operations-marketing interface

Life Trajectories of female child abuse survivors thriving in adulthood

A narrative study of thriving adult female survivors of childhood maltreatment was undertaken to discover how they had achieved success. Life trajectory patterns, turning points, and setbacks were identified. Data consisted of 81 interview transcripts derived from a series of three interviews, spaced over 6 to 12 months, with 27 survivors. The childhood abuse was intrafamilial, beginning as early as infancy and continuing, in most cases, until participants left home. The onset and pace of the healing trajectory were quite variable, including a roller-coaster pattern as well as patterns of slow, steady progress and continued struggle. Four types of redemption narratives were delineated. Survivors had not been spared depression but had made achievements in work and education and displayed remarkable generativity, parenting their own children well, and mentoring other young girls, especially victims of abuse

Effects of methyl-thiouracil on liver vitamin A, spermatogenesis and calcium metabolism of merino rams

It has been suggested that in north-western Queensland hot weather depresses the activity of the thyroid and thus reduces the efficiency of conversion of the small amount of available carotene. This could produce a vitamin A deficiency, which in turn might affect the thyroid and so set up an adverse cycle (Moule, 1950). The experiment reported here was designed to test this hypothesis. Facilities for simulating the temperatures of north-western Queensland were not available, so methyl-thiouracil was used to depress the activity of the thyroid
