In the labor surplus economies of Pacific Island nations un(der)employment and a lack of income inhibit social and economic development, restrict educational opportunities and contribute to social unrest.

Mares, Peter; Maclellan, Nic http://biblioteca.universia.net/ficha.do?id=39806656 This paper elaborates on the effects of a rise in energy costs for Dutch glasshouse horticultural producers. The effects on production, bilateral trade and consumption in 25 European countries plus Morocco, Turkey and the Rest of the World, are estimated using a version of the HORTUS partial equilibrium supply and demand model. This model includes 11 sorts of fruit and vegetables, and two categories of ornamental plants and flowers. As energy, especially natural gas, is a major intermediate i...

Tras la caracterización de esta actividad productiva, se analizan 230 encuestas directas a horticultores y 50 entrevistas a técnicos agrarios realizadas en la campaña 2004/2005, calculando la productividad aparente y los precios de nivelación y cierre para los cultivos más característicos. Seguidamente se ...

We examine whether increasing off-farm employment opportunities for rural households-resulting from increased horticulture exports and associated agro-industrialization-has benefitted the smallholder farm sector through investment linkages. We use data from a household survey in the main horticulture export region in Senegal. We find that access to unskilled employment in the export agro-indust... Miet Maertens http://biblioteca.universia.net/ficha.do?id=39811785 In this paper we address the question of farm-nonfarm linkages at the household level for a case-study in Senegal. We examine whether increasing off-farm employment opportunities for rural households ?resulting from increased horticulture exports and associated agro-industrialization ?has benefitted the smallholder farm sector through investment linkages. We use data from a household survey in the main horticulture export region in Senegal. We find that access to unskilled employment in the e... Miet Maertens http://biblioteca.universia.net/ficha.do?id=44807364 Kats, Hans http://biblioteca.universia.net/ficha.do?id=39928049 We propose a test of the Porter hypothesis for the Dutch horticulture sector, using a stochastic production frontier analysis allowing for an inclusion of policy variables to account for the effect of environmental policy of firm performance. We find considerable heterogeneity in the way firms react to environmental policy measures. Our estimation results indicate, for example, that a 1997 voluntary agreement covering energy, nutrient and pesticides use enhances technical efficiency of vegeta... van der Vlist, Arno; Withagen, Cees; Folmer, Henk http://biblioteca.universia.net/ficha.do?id=40241890 This article calculates nonparametric measures of total factor productivity growth on Dutch horticultural firms in the period 1976-1995. Individual components of total factor productivity growth, i.e., efficiency change and technical change are regressed on socioeconomic factors reflecting the effects of the world oil crises, household and demographic characteristics, location, and investment in physical capital. Also, the article investigates the presence of inter-sector spill-overs between ... Alfons Oude Lansink; Igor Bezlepkin http://biblioteca.universia.net/ficha.do?id=46209747 Support Vector Machines (SVM) over the past six years have emerged as one of the more robust classification architectures coupled with good generalisation capabilities. Similarly the Evolving Fuzzy Neural Network (EFuNN) have also been reported to posses these properties as well. This paper compares these two models and then applies them to the classification of two datasets taken from the horticulture industry. The results that are reported indicate that the EFuNN performs comparably well ag... Brendon J. Woodford http://biblioteca.universia.net/ficha.do?id=40167093 Diversification of agriculture is considered as an important strategy for agricultural development in India and importance of horticulture crops as a means of diversification and creation of employment opportunities in rural areas is recognized. Besides, it also leads to agro-industries’ development and value addition. In India, horticulture accounts for 8.5% of the gross cropped area and occupies second position in fruits production and first position in vegetables production. Although, the ... Ira Das; M K Dutta; S Borbora http://biblioteca.universia.net/ficha.do?id=47043657 Two types of series of h-indices for journals published in the field of Horticulture during the period 1998-2007 are calculated. Type I h-indices are based on yearly data, while type II h-indices use cumulative data. These h-indices are also considered in a form normalised with respect to the number of published articles. It is observed that type I h-indices, normalised or not, decrease linearly over a period of ten years. The type II series, however, is not linear in nature: it exhibits part... Liu, Yuxian; Rao, I. K. Ravichandra; ROUSSEAU, Ronald http://biblioteca.universia.net/ficha.do?id=521004 Vários procedimentos de comparações múltiplas têm sido usados para explicar a resposta de tratamentos testados em experimentos agronômicos. Entre esses, está o uso de testes de comparação de médias, muitas vezes apropriados a alguns tratamentos e inteiramente inapropriados a outros. Um levantamento e uma avaliação do uso e mau uso desses testes foi realizado com os trabalhos publicados na revista Horticultura Brasileira no período de 1.983 a 2.000. Procedimentos alternativos são sugeridos par... Bezerra Neto,Francisco; Nunes,Glauber Henrique S.; Negreiros,Maria Zuleide de http://biblioteca.universia.net/ficha.do?id=39913192 Using 2002 survey data, this study employs log-linear regression analysis to examine the effects of migrant labor on wages, hours, and gross sales in Alabama's horticulture industry. A binomial probit model is added to measure producer decisions to hire migrant workers. The presence of migrant workers is found to raise average wages within green industry firms, but exhibits no significant effects on hours and sales.
