Potential of feed additives to improve the environmental impact of European livestock farming: a multi-issue analysis

Today, less than 3% of the 250,000 plant varieties available to agriculture are in use. Sources of (agricultural) biodiversity are under threat and disappearing in many regions. Increasing industrialisation of agriculture and top-down agricultural research have contributed to this dependence on a relatively few plant varieties. This article argues that new approaches to agricultural development research are needed to conserve agricultural diversity, improve crops, and produce food of quality for all. Such an approach should enable small farmers on marginal lands to participate as equal partners alongside agricultural scientists, fairly sharing their know-how, expertise and seeds. Three case studies illustrate how farmers and plant breeders are working together in a diversity of agro-ecological, socio-economic and political contexts to put these new approaches into practice. New forms of collaboration are producing an increase in diversity and a number of promising improved varieties in terms of yields, agronomic traits and taste. These varieties are showing better adaptation to the local environmental conditions without requiring extra external inputs. Long-term success requires that these efforts be backed up by supportive policies, by actions to ensure that policies are implemented, and where necessary by related legislation.     

Carbon accounting tools: are they fit for purpose in the context of arable cropping?

The agricultural sector contributes 9% towards total UK greenhouse gas emissions and so may offer significant potential as a sector to help meet national and international emission reduction targets. In order to help farmers manage their emissions and to encourage more sustainable farming, several carbon accounting tools are now available. This article describes a short study that selected five suitable tools and compared their performance on nine European arable farms, concentrating on the crop production components, to determine how useful they are for assisting in the development of site-specific mitigation strategies and how well they would perform within farm assurance or benchmarking schemes. The results were mixed, with some tools better designed for identifying mitigation opportunities than others. The results also showed that, quantitatively, the results are highly variable between tools and depended on the selected functional unit, this being highly important if the wider aspects of sustainability such as food security are to be considered. However, there is statistical consistency across the tools regarding the ranking order of the farms in terms of their emissions.

Another Piece in the Feldstein — Horioka Puzzle

Using UK quarterly data, we re-examine the nature and degree of the relationshipbetween savings and investment by means of a newly developed bounds testingprocedure to cointegration within an autoregressive distributed lag (ARDL)framework. Our finding of cointegration in all samples considered is consistent withthe view that the long-run relationship between savings and investment is notexclusively dependent upon the level of financial integration. The evidence alsoindicates that this relationship weakens after the abolition of UK controls oncapital flows in 1979, suggesting that the Feldstein-Horioka framework providesat least a partial measure of the degree of capital mobility.     

What makes a good project manager?

There is a growing awareness within project‐based sectors of the relationship between performance and managers' competencies. This article reports on research that investigated the competency profile of ‘superior’ project managers working within the construction industry, one of the most complex and dynamic project‐based industrial sectors. The study combined an assessment of both their behavioural competencies and job‐task competencies. The results reveal that while their job‐task competencies are highly specific to the industry in which they work, the behavioural competencies of superior project managers are mostly generic in nature and apply to a range of other management positions. This research shows how it is practically possible to identify the competency profile of superior managers and utilise this framework for managing the performance of this key management group.     

The good,the bad,and the ugly: 30 years of US airline deregulation

The US airline industry was deregulated in 1978 and has undergone significant changes in industry structure, profitability, employment, passenger volume, and patterns of service and fares, among other characteristics. This paper sets out to make three contributions to the literature as related to the story of airline deregulation. First, discussion of economic theory will provide the context for an updated overview of the positive, negative, and really negative results of US airline deregulation, summarized in the form of “the good”, “the bad”, and “the ugly”. Second, this paper provides a periodization of the 30-year history of US airline deregulation that is important in understanding the cycles of change as reflected in the industry’s financial performance and other relevant data. Third, this paper contributes to the renewed debate about the efficacy of deregulation and liberalization policies, particularly at a time when the global financial crisis has cast a harsh spotlight on the (un)desirability of these policies. Some of the good results during the 30 years of airline deregulation, from the industry and consumer perspective, include higher passenger volumes, more service to the most popular destinations, and lower fares on average. Bad results include financial and employment instability, diminution in the quality of airline service overall, and fewer flights and higher fares to smaller places. The recent 2000–2005 period has been particularly ugly, as the airline industry has lost over $30 billion, and several high-profile carriers, such as United, Delta, Northwest, and US Airways, were forced into bankruptcy.     

Technological and economic long waves and their implications for employment

The world economy is currently stuck in a 'long wave' downswing, due largely to the mismatch of a new technological 'style' with established institutions. The article sketches the effects on the level and pattern of employment and discusses the reforms which will be needed to escape from the downswing.     

Believing Is Seeing: Joint Ventures and Organization Learning*

This paper develops a conceptual framework for the study of organization learning and applies it to learning in joint ventures (JVs). the framework presents a multilevel view of the phenomenon, suggesting that learning in organizations occurs at the individual, group and organization levels. the framework integrates behavioural and cognitive perspectives of organization learning and delineates both learning processes and outcomes. Four key elements of organization learning are addressed: the nature of managerial learning experiences, the sharing and integration of managerial learning within an organization, the insti-tutionalization of learning, and the relationship between organization learning and performance. In applying the framework to a study of learning and JVs, we observed firms with explicit learning objectives unable to put into place the appropriate mechanisms and systems to transfer knowledge from the JV to the parent. While individual managers in the JVs were often enthusiastic and positive about their learning experiences, integration of the learning experience at the parent firm level was problematic, limiting the institutionalized learning. the fundamental position in this paper is that a rigid set of managerial beliefs associated with an unwillingness to cast off or unlearn past practices can severely limit the effectiveness of organization learning.

Theorising South Africa’s Corporate Governance

South Africa’s principal corporate governance report aspires to an ‘inclusive’ approach to corporate governance, in which companies are clearly advised to consider the interests of a variety of stakeholders. Yet, in common with many other countries, there is little discussion of the theoretical foundations and assumptions implicit in the recommended approach to corporate governance. The purpose of this article is to provide an analysis of corporate governance and the corporate environment in South Africa in terms of existing theory and models of corporate governance, and to provide a critique based on a consideration of traditional African values and the socio-economic necessities of post-apartheid South Africa. The result is the identification of an incompatibility between the current corporate environment in South Africa and the given exposition of African values. Some prospects for change are then identified.
