Several breeds of West African shorthorn cattle (Bos taurus brachyceros) are now at high risk of extinction due to interbreeding. The West African shorthorn breeds are particularly important resources because of their superior abilities to resist diseases, particularly trypanosomosis, and be productive under high humidity, heat stress, water restriction and with poor quality feed. A study was undertaken in the derived savanna area of southwest Nigeria to determine the prospects for conservation through use and possible improvement of the Muturu, a West African shorthorn breed known to be in decline throughout southern Nigeria. An analysis of farmers’ breeding practices and breed preferences confirmed a strong trend away from Muturu and identified the traits farmers find least desirable about the Muturu relative to other breeds. An analysis of cattle market prices found small, but significant, price differences by breed. The best hopes for increased utilization likely in other areas of West Africa, such as southeast Nigeria, where the Muturu is better suited to the farming systems and there is a large market for this breed.","PeriodicalId":338433,"journal":{"name":"The research reports","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133233367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wanmali","doi":"10.2307/633942","DOIUrl":"https://doi.org/10.2307/633942","url":null,"abstract":"The report traces the development over a decade of the regional economy and the provision of services by government and private sector for both dry and irrigated tracts in a rural area of India, based on empirical evidence from Miryalguda, Andhra Pradesh. The study analyzes the irrigation, cropping patterns, and population of the regional economy, identifies rural and retail services provided and their distribution among service centres, size of the service areas, number of people served, examines the spatial impact of service provision, the effects of service provision on the agricultural sector; and the development of the region from a spatial or geographical viewpoint. The cropping pattern of the study area has changed from a dry-crop economy growing rainfed paddy (unhusked rice), jowar, groundnuts, castor, and pulses, to one growing sugarcane and seasonal vegetables as well, and able to cover a more extensive area and crop more than once a year. The cropped area increased from 102 000 acres in 1968 to 185 000 acres in 1978. The extension, intensification, and diversification of the cropping pattern was facilitated by the simultaneous provision of education, health, credit, banking, transport, marketing, storage, communication, and input distribution facilities. In 1968 the index of total services provided was 4.63 for the taluka, 4.50 for the irrigated tract, and 4.71 for the dry tract. In 1978 these indexes were 9.94, 5.86, 13.90 respectively. Mobile services, perhaps operated in conjunction with market days, would make services both more accessible and cheaper","PeriodicalId":338433,"journal":{"name":"The research reports","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128773341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicate high long term costs if heavy reliance on chemical pesticide control methods continues, due to a pesticide resistance buildup in the mosquito populations. Physical source reduction methods were shown to be more efficient both in the short and long run. A linear programming model is presented which optimizes the mix of chemical and physical control methods. Results indicate increasing costs of mosquito abatement as pesticide effectiveness declines. Simulation results of narrow spectrum pesticide manufacturing firms indicate negative returns to research, development and marketing for most firms even with significant subsidies.

It is at the second Earth Summit with its “Environment and Development” motto, which was attended officially by 172 countries and approximately 2400 representatives of non-governmental organisations, where unsustainable consumption and production were recognised as the most important causes of growing global development problems. Attempts were made to find models of sustainable and stable economic development that took into account the protection of ecosystems from overexploitation and determinants of ecological human activity. It was no accident that this process coincided with the progress of economics of sustainable development. This article aims at providing an insight into economics of sustainable development and presenting its historical roots. The issues herein do not describe its whole range, but only selected elements. The structure of this article is as follows. The first part focuses on the origins, concept and principles, objectives and orders of sustainable development. Further, the concept and assumptions of sustainable development economics and homo sustinens as the basic underlying notion are discussed.","PeriodicalId":338433,"journal":{"name":"The research reports","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128768213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, not every entrepreneur exercises innovation and not every innovation leads to entrepreneurship. University Business Incubators (UBIs) have been considered as the main factor for entrepreneurial process in which if innovation takes place, the perspective of economic success becomes wide open. Currently, UBIs are typified and considered around the world as guides in the process of entrepreneurship; one of their objectives is the creation of startups that can eventually consolidate in the market. The aim of this work is to identify by means of the Analytic Hierarchy Process (AHP) the priority of UBIs performance criteria on the basis of the main levels of impacts the litera- ture remarks on: a) economic action, b) National Development Plan and/or c) scientific action. These criteria are related with four characteristic UBIs functions: i) provision of means of production, ii) strengthening entrepreneurship culture, iii) bonding with the mar- ket to generate a base of future firms, and, iv) creating pull effect. The hypothesis of this work is that UBIs classification not only allows for identifying their main characteristics but it also points toward a normative application of criteria and alternatives of performance, in order to reach the objective of creating and fostering solid and stable enterprises, no matter the sponsoring university characteristics. We tested it by analyzing the three most important Mexican UBIs. The results show that although the analyzed UBIs are a specific type of business incubators, their criteria and alternatives of performance differ among them.","PeriodicalId":338433,"journal":{"name":"The research reports","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123339863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
