Farmers are constantly exhorted to be good marketers. This research explores the connection between production characteristics and producer business orientation in the Spanish citrus industry. The sector lends itself to this study because it is by far the world's largest exporter of fresh oranges and mandarins, and yet has been criticised for fundamental weaknesses not only in the structure of production systems but also in the patterns of marketing activity. Survey data from Valencia are used to test the assumption that specialised producers also possess enirepreneurial attitudes and attributes. Cluster analysis is used to identify strategic groups of producers according to production characteristics and producer business orientation. The complexity of the industry is found to defy simple polar hypotheses about “good” and “weak” structures and strategies. 相似文献

Selling two environmental services: In-kind payments for bird habitat and watershed protection in Los Negros, Bolivia 总被引:3,自引:0,他引:3
Marketing several environmental services from a single area can help access diverse sources of funding and make conservation a more competitive land use. In Bolivia's Los Negros valley (Department of Santa Cruz), bordering the Amboró National Park, 46 farmers are currently paid to protect 2774 ha of a watershed containing the threatened cloud-forest habitat of 11 species of migratory birds. In this payment for environmental services (PES) scheme, annual contracts prohibit tree cutting, hunting and forest clearing on enrolled lands. Farmer-landowners as service providers submit to independent yearly monitoring, and are sanctioned for non-compliance. Facilitated by a local NGO, Fundación Natura Bolivia, one service buyer is an international conservation donor (the US Fish and Wildlife Service) interested in biodiversity conservation. The second service users are downstream irrigators who likely benefit from stabilized dry-season water flows if upstream cloud forests are successfully protected. Individual irrigators have been reluctant to pay, but the Los Negros municipal government has on their behalf contributed ~ US$4500 to the scheme. The negotiated payment mode is annual quid pro quo in-kind compensations in return for forest protection. Predominantly, payments are made as “contingent project implementation”, transferring beehives supplemented by apicultural training. With regard to service provision, environment committees and education programs have increased awareness in downstream communities of the probable water-supply reduction effect of continued upstream deforestation. External donors have funded subsequent studies providing basic economic, hydrological and biodiversity data, and covered PES start-up (~ US$40,000) and running transaction costs (~ US$3000 per year over the last three years). The greatest challenges in the development of the PES mechanism have been the slow process of building trust between service buyers and providers, and in achieving clear service-provision additionality. 相似文献

How to motivate your problem people 总被引:2,自引:0,他引:2
Nicholson N 《Harvard business review》2003,81(1):56-65
Managers who motivate with incentives and the power of their vision and passion succeed only in energizing employees who want to be motivated. So how do you motivate intractable employees--the ones who never do what you want and also take up all your time? According to Nigel Nicholson, you can't: Individuals must motivated themselves. Nicholson advocates a method that turns conventional approaches to motivation upside down. Instead of pushing solutions on problem employees, the manager should pull solutions out of them by creating circumstances in which the employees can channel their motivation toward achievable goals. That means addressing any obstacles-possibly even the manager's own demotivating style--that might be hindering the employees. The author's method demands that a manager take charge of a difficult situation and resolve it. An investment of time is required, but it will bring the manager to a resolution sooner than other means would. Using detailed examples, Nicholson walks the reader through his method, pointing out potential pitfalls along the way. First, the manager creates a rich picture of the problem person. Second, the manager exercises flexibility and reframes goals so that the employee can meet them. Third, in a carefully staged, face-to-face conversation, the manager meets with the problem employee on neutral ground. Whether a problem is solved or simply resolved, the payoffs from using this method extend beyond the specific employees who have been difficult to motivate. Besides increasing a manager's chances of motivation problem people, the method can inspire an entire team by signaling that the organization deals with difficult people rather than discarding them. 相似文献

Recent observations of spawning lake trout Salvelinus namaycush near Drummond Island in northern Lake Huron indicate that lake trout use drumlins, landforms created in subglacial environments by the action of ice sheets, as a primary spawning habitat. From these observations, we generated a hypothesis that may in part explain locations chosen by lake trout for spawning. Most salmonines spawn in streams where they rely on streamflows to sort and clean sediments to create good spawning habitat. Flows sufficient to sort larger sediment sizes are generally lacking in lakes, but some glacial bedforms contain large pockets of sorted sediments that can provide the interstitial spaces necessary for lake trout egg incubation, particularly if these bedforms are situated such that lake currents can penetrate these sediments. We hypothesize that sediment inclusions from glacial scavenging and sediment sorting that occurred during the creation of bedforms such as drumlins, end moraines, and eskers create suitable conditions for lake trout egg incubation, particularly where these bedforms interact with lake currents to remove fine sediments. Further, these bedforms may provide high-quality lake trout spawning habitat at many locations in the Great Lakes and may be especially important along the southern edge of the range of the species. A better understanding of the role of glacially-derived bedforms in the creation of lake trout spawning habitat may help develop powerful predictors of lake trout spawning locations, provide insight into the evolution of unique spawning behaviors by lake trout, and aid in lake trout restoration in the Great Lakes. 相似文献

In many cases of technological development, successive generations of a technology evolve, each more efficient than its predecessor. It has been assumed when modeling and forecasting the adoption of these technologies that the market reaction to each generation was similar. Using the terminology of the Bass model, this similarity is encapsulated in the assumption that the coefficients of innovation and imitation are constant. New data for two and three generations of mobile telephone technology from eleven countries are modeled. The modeling framework used—simultaneous estimation for successive generations using a full information maximum likelihood procedure—demonstrates that, in most cases, the hypothesis of constant coefficients can be rejected. Use of a model with changing coefficients is shown to considerably improve forecasting performance. These results were reinforced by analysis of data for four generations of IBM mainframes. 相似文献

This paper views German Monetary Union as a sequence of large asymmetric shocks to the European economies. As such it can be analysed with a large, new-Keynesian macro-econometric model of the relevant economies such as NiGEM. The ‘news’ in the sequence of shocks is assessed by analysing contemporary, NiGEM based, forecasts, and important events are then ‘peeled-off’ in reverse order. The resulting counterfactual history analyses the effects of the collapse of the Soviet economy on the EC and Scandinavian economies, and it is argued that the recession in countries such as Finland was not primarily caused by trade effects. The costs of support programmes for East Germany are then removed, creating a negative fiscal shock. Finally the paper analyses the overall effects of the set of shocks. In each part of the counterfactual history, individuals from forward looking expectations and the authorities operate fiscal solvency rules and target monetary aggregates. 相似文献

Recent concerns have focused on the adequacy of the power of Marketing Departments to implement the marketing concept and
to put into effect marketing plans and strategies. The article analyzes the marketing function as an information processing
activity, where one significant element of information processing is sales forecasting as an uncertainty absorption process.
The major hypothesis is that the power of the Marketing Department can be partially explained by its control of sales forecasting,
both directly but also indirectly through a set of strategic contingencies which make marketplace uncertainty critical to
the firm. The argument is supported by empirical data from a study of manufacturing firms in the United Kingdom, and leads
to the identification of a number of implications for managers and researchers. 相似文献
