Fish farming in Europe: Commercial and political dimensions

The author argues that, because of considerable scope for increased production efficiency, farmed fish will provide strong competition for caught fish, and eventually for animal protein from land agriculture. Demand response will be tempered by low price elasticities, while certain other factors (such as the wider choice offered by the growing range of farmed fish species) will stimulate consumption. In all countries, governments have a role to play-eg undertaking basic biological research. This role for government, together with the challenge presented by fish farming to its competitors, explains why politics will be important in determining the rate at which the new industry will expand.     

The influence of policy networks on policy output. A comparison of organic farming policy in the Czech Republic and Poland

Although, at the time of accession to the EU, organic farming policies formally were equally developed in the Czech Republic and Poland, a closer investigation reveals some variation. This paper takes a policy network perspective to explore the policy differences between these two countries. Common network themes are used to link networks with policy output. It is argued that the capacity of the organic sector and its structural organization, its cohesion, and the relationship between organic interest groups and the government affect the political discourse, and, in consequence, how organic farming policy is elaborated.     

The clock project: gears as visual-tangible representations for mathematical concepts

As we have noticed from our own classroom experiences, children often find it difficult to identify the adequate operations learned in mathematics class when they are solving mechanical-operators problems in Technology class. We wanted to design a project that exploits the idea of a hands-on relationship between mathematics and technology to teach students the concept of ‘transmission coefficient’ in schools. Our purpose was to bridge mathematical knowledge and mechanical parts in technological devices. Our belief was that visual-tangible representations enhance human cognition by scaffolding the information process. We supplied a kit with rubber foam (Fomi) and balsa wood parts to construct an analogical clock. This included a series of gears to work with three different ratios. The project was conducted in 2007 and 2008, with 38 students ranging from 10 to 14 years of age. The students were from the 5th and 7th grades in two different schools. The project included six stages of both theory and hands-on work. In a final stage, the students were given a written test. All students were able to make workable systems of their design for a time-measuring device. This proved important for technological education. On the other hand, manipulating gears along with visual reasoning strategies allowed all students to achieve an understanding of operations with fractions. We think this is a major achievement in mathematical education.     

Managing the search for new product concepts: a strategic approach

Abstract
The authors point out that there is little in the academic literature about the way ideas for new products emerge and how the emergence is managed. They have identified the main top management problem as the strategic one of achieving the right balance between resources put into new product search and those put into current business operations. To obtain more information on good and bad practice in this area they have investigated how a specially selected sample of small to medium-sized Canadian technological companies actually carry out new product search.
The research method was to ascertain how far corporate goals, organization structures and corporate values affected the effectiveness of new product search. Unstructured interviews were conducted with senior staff in the companies, during which information was sought about company goals, innovation strategy, internal relationships and how these impinged on the genesis of 35 projects.
The authors found an important corporate goal spurring innovation was growth (or survival), to be achieved by using new products to dominate their markets. R&D was oriented to achieving a technical edge, though not necessarily a radical breakthrough in market driven ways. Few had effective formal strategic plans for new product search. On the whole, top managements emphasized the importance of individual initiative and commitment to get results and the necessity of open communication throughout the organization.
Overall, this research reveals once more that any organization that wishes to pursue a strategy of product innovation has to build a climate which explicitly favours that strategy. Corporate strategy, itself, has a major influence on that climate. New product search requires resources and a place in the strategic plan but the extent to which it can be formalized is limited. It must be possible for new ideas, wherever generated, to emerge and gather momentum informally.     

Towards a strategy for fish farming in the UK

The UK's fish farming industry, though not yet making a significant contribution to the national food supply, appears to be developing towards an annual production level of about 20 000 tonnes by the mid 1980s. The author discusses the prospects and constraints for the different farmed species, legal and organizational problems, the market, and research and development activities. The role of the industry in creating new wealth and widening consumer choice is stressed.     

Matters of food and farming in Asia

Leaving aside the plantation enclaves, the problems of food and farming in Asia are centred on subsistence farming. This, in spite of recent improvements in farming techniques, remains subject to natural hazards, population pressure and risks which only those with ready access to land, labour, capital and know-how are able to face. By comparison, small cultivators, tenants and landless labourers suffer serious disadvantages. These can be reduced only as a result of reforms which bring security of tenure, transfers of land and a just system of land tax combined with public works programmes. Thus economic growth, coupled with social equilibrium and political stability, could be achieved.     

Servitization and deservitization: Overview,concepts, and definitions

The topic of servitization has generated a considerable body of research and many conferences, as well as industry engagement. Yet, despite the extensive literature associated with this now-mature discipline, there is no broad-based consensus on the core concepts and definitions deployed by servitization scholars, and both terminology and usage often seem ambiguous. This paper examines challenges related to service growth strategies, as well as strategies involving deservitization or a retreat from service offerings. Showing that these strategies have been pursued for more than fifty years, clarification is sought here by framing the corresponding processes and proposing definitions for four core terms: servitization, service infusion, deservitization and service dilution. It becomes clear that in focusing on the organizational change entailed by these processes, future research must elucidate “softer” issues such as leadership and business logic.     

Profit Sharing and Public Policy: Insights for the United States

Nations differ in their approach to profit sharing, with policies ranging from nonintervention to mandatory sharing. Mounting evidence that profit sharing has a positive impact on employment and productivity has spurred some American legislators and economists to propose additional tax incentives. While this option has been effective in increasing the number of plans, a more prudent response would be the creation of a national tripartite body to accelerate and enhance the quality of profit-sharing research.     

Rice farming in Nigeria : in praise of the smallholder

Food production policy in Nigeria is now oriented towards large scale commercial production. The Federal Government proposes 20000 hectares of public cassava farming in all 19 states and in the Abuja capital territory. The National Grains Board and the National Root Crops Production Company are establishing large farms in their operational zones. The Nigerian Agricultural and Cooperative Bank is loaning millions of naira to individual private farmers to encourage them to establish large farms. Virtually every state government has its Agricultural Development Corporation directly involved in agricultural production on a large scale. It is presumed that the smallholder system on which Nigeria currently depends is inefficient and could not be relied upon to achieve the necessary increases in production.     

Savings and Loan Demand for Liquid Assets: Theory,Evidence and Implications for Policy*

In this study a model of liquid asset management for individual savings and loan associations is developed. The model combines features of portfolio theory and inventory theory and is used to draw hypotheses on the relationship between the demand for excess liquidity and a variety of independent variables. Pooled cross section-time series equations are estimated for the demand for excess liquidity of 198 S & Ls over the period 1974–1978. In addition to conclusions on the role of individual variables, the estimated equations reveal that the FHLBB can affect the portfolios of some, but not all, S & Ls. This implies that FHLBB liquidity policy can have an effect on the mortgage market.     

Cloud Computing: Architectural and Policy Implications

Cloud computing has emerged as perhaps the hottest development in information technology. Despite all of the attention it has garnered, existing analyses focus almost exclusively on the issues surrounding data privacy without exploring cloud computing’s architectural and policy implications. This Article offers an initial exploratory analysis in that direction. It begins by introducing key cloud computing concepts, such as service oriented architectures, thin clients, and virtualization, and discusses the leading delivery models and deployment strategies being pursued by cloud computing providers. It then analyzes the economics of cloud computing in terms of reducing costs, transforming capital expenditures into operating expenditures, aggregating demand, increasing reliability, and reducing latency. It then discusses the architectural implications of cloud computing for access networking (focusing on bandwidth, reliability, quality of service, and ubiquity) and data center interconnectivity (focusing on bandwidth, reliability, security and privacy, control over routing policies, standardization, and metering and payment). It closes by offering a few observations on the impact of cloud computing on the industry structure for data centers, server-related technologies, router-based technologies, and access networks, as well as its implications for regulation.     

Targeting agricultural research and extension for food security and poverty alleviation: A case study of fish farming in Central Cameroon

Over 5 years of participatory on-farm research, market access, profitability, farming systems productivity and economic sustainability were compared on 100 small-scale farms in Central Cameroon. Integration technology based on the use of agricultural by-products as fishpond inputs was the driver for intensification. Over all farms, fishpond productivity increased from 498 kg to 1609 kg fish/ha (2145 kg/ha/yr). During the project period, the number of active fish farmers increased from 15 to 192 (including 55 farms which participated only through information exchange). Over all farms, net returns from aquaculture increased by 5 times over pre-project levels. Productivity, intensity and profitability increased more significantly in periurban areas with good market access, compared to rural areas. Among farmers with good market access, average net income from the aquaculture enterprise rose from $118 up to $1485. Research-Extension Team (RET) support cost an average of $61,300 per year. Over 5 years, rural farmers recaptured 23% of the relevant RET investment compared to 442% by periurban farmers. Likewise, increase in production attributable to RET intervention was higher for periurban (253%) compared to rural (11.3%) fish farmers. Within 3 years of the end of extension support, rural farmers had returned to pre-project production levels, whereas periurban farms had better maintained their productivity and profitability. Findings indicate that, in areas with little or no access to markets, the number of fishponds and fish farmers can be increased and yields improved, increasing local food supplies, but sustainability in the absence of extension subsidies is questionable. To achieve either of the two principal goals for the sector, food security and/or poverty alleviation, investments need to be made in improving the availability of quality technical assistance to targeted farmers and finding means of reducing social conflict arising from perceived inequalities in the accrual of the benefits of development.     

The implementation of organic principles and values in the European Regulation for organic food

The paper is based on selected findings of the research project EEC 2092/91 (Organic) revision. It contributes to an improved understanding of the core ethical values associated with and principles of organic farming, analyses reference to such values in the European Regulation (EEC) 2092/91 and its ongoing revision, and contrasts them with current practice of organic agriculture. An analysis of differences in the implementation of the Regulation by national governments and private standards is presented. Ethical values are per se in need of interpretation, so the final section sets out procedural issues arguing for a deliberative model of decision-making, when aiming to achieve a coherent integration in the structure of a regulation.     

Agricultural technologies for climate change in developing countries: Policy options for innovation and technology diffusion

Climate has obvious direct effects on agricultural production. The reverse is more apparent than ever as greenhouse gas emissions from agriculture are tallied. The development and effective diffusion of new agricultural practices and technologies will largely shape how and how well farmers mitigate and adapt to climate change. This adaptation and mitigation potential is nowhere more pronounced than in developing countries where agricultural productivity remains low; poverty, vulnerability and food insecurity remain high; and the direct effects of climate change are expected to be especially harsh. Creating the necessary agricultural technologies and harnessing them to enable developing countries to adapt their agricultural systems to changing climate will require innovations in policy and institutions as well. Potential constraints to innovation involve both the private and public sectors in both developing and developed countries. The process of transferring agricultural innovations across agroecological and climatic zones is often subject to agronomic constraints. Often, the most binding constraints occur at the adoption stage, with several factors that potentially impede poor farmers’ access to and use of new technologies. Based on discussions of these constraints, we derive six policy principles and use these principles to suggest several specific investments and policy priorities.
