This article assesses the controversy surrounding a high-profile agricultural investment initiative, the Southern Agricultural Growth Corridor of Tanzania (SAGCOT), which aims to modernise, commercialise, and transform Tanzania’s agricultural sector. Drawing on a review of SAGCOT literature and findings from consultations with SAGCOT stakeholders and intended beneficiaries, the article outlines the polarised narratives of “opportunity” and “risk” informing SAGCOT debates, and presents research findings that challenge these narratives. The findings suggest that agricultural investments are rarely as glamorous or as gloomy in practice as the polarised narratives around SAGCOT suggest, and illustrate the challenges involved in directing agricultural investments in ways that balance multiple interests and objectives in practice.  相似文献

There are some fascinating historical parallels between Mexico’s giant teacher union, the Mexican National Education Union, and the South African Democratic Teachers Union. Although both teacher unions played an important role in challenging political oligarchies at certain points in their history, they became increasingly protectionist. Through their close affiliation to ruling parties, they were able to wield substantial political influence. In both of these cases, the unions played a controversial role in preventing central government surveillance and intervention in schools. Arguably, this often allowed not only for corruption in appointments and promotions, but also the protection of negligent teachers. There is some evidence to suggest that in protecting their sectional interests, both unions have frequently alienated parents and students at the community level. This paper addresses broader debates about the impact of powerful teacher unions on the quality of public schooling.  相似文献

Tribal communities of India have been facing financial challenges for many years, and these have increased alongside commercialisation led by industrialisation. The major reason for this is that tribal communities are neglected by the state, which has had a negative impact on their livelihoods and financial status. The state has made some attempts to promote these communities, but these have been unsuccessful. Against this background, this article explores the financial practices of tribal communities in Jhabua district of Madhya Pradesh, India and presents a microfinance model which could be suitable in the Jhabua context.  相似文献

This article assesses the factors determining the type of rubber product that farmers are willing to sell and the factors influencing their marketing channel choice in Thailand. Primary data were collected through questionnaire administration from 280 rubber farmers in two southern provinces. The results of the logit regression model revealed that membership of farmers’ organisation, access to knowledge and information, and total area of immature rubber positively influenced the sale of fresh latex. Membership of farmer organisations and accessibility to market infrastructure also significantly positively influenced the sale of fresh latex to farmer groups. The implications for rubber marketing are presented.  相似文献

In the wake of the impasse in the Doha Development Round of multilateral trade talks, sector-specific plurilateral trade agreements (PTAs) have been gaining traction. However, PTAs mostly appeal to developed countries, with the uptake among developing countries (including least-developed countries) being very limited. This article investigates the factors contributing to such a phenomenon, whether there is indeed merit in developing countries playing a more active role in PTAs and how they might be encouraged to do so. Both qualitative and quantitative analyses were conducted with specific attention being given to the effects, on a selection of developing countries, of participation in four PTAs: the Trade in Services Agreement, the Government Procurement Agreement, the Environmental Goods Agreement and the Information Technology Agreement II. Among the findings was that although, according to the qualitative analysis, policymakers are generally disinterested in the four PTAs because they are not aligned to the countries’ economic interests or they threaten policy space, the quantitative analysis revealed that gains could often be made from more active participation in these agreements. This clearly points to a research gap and highlights the need for more in-depth analysis of the potential of PTAs in the developing world.  相似文献

杠杆收购的本土化研究   总被引:1,自引:0,他引:1  
杠杆收购作为公司并购的一种特殊形式,始于20世纪70年代的美国,80年代达到高峰。其特征在于收购资金主要来源于市场融资,收购的目的是以更高的价格出售公司或公司的股票。因此,杠杆收购较之传统意义上的公司收购有很大的区别。杠杆收购的发展,离不开低信用等级债券的辅助。作为杠杆收购中最有特色的融资手段之一,低信用等级债券的独特优势使其成为杠杆收购中最为最活跃的分子。在我国现实背景下,杠杆收购有其本土化发展的空间和可能性。  相似文献

Document examiners are frequently asked to determine whether or not a colour printout has originated from a particular inkjet printer. The printer can rarely be identified unless some unique defects or irregularities of the printer are present on the printout. However, it is possible to decipher the make and/or model of the printer by comparing the ink-profile of the questioned printout with that of a seized inkjet printer cartridge or from one in a database. This paper presents an overview of a systematic approach to characterising and discriminating the inks of different inkjet printer cartridges using thin layer chromatography (TLC) and high pressure liquid chromatography (HPLC) with multi-wavelength ultra-violet/visible (UV/Vis) detection. Ink samples from 23 different inkjet printer cartridges (including originals and substitutes) of different brands and colour printouts, printed by known printers were examined with newly developed chromatographic methods. Subsequently, a database of the ink-profiles was generated. The methods provide a useful tool for discriminating coloured inks in inkjet printer cartridges of different brands.  相似文献

Legal context: When Congress enacted the Federal Trademark Dilution Act in1996, it intended to create a uniform federal cause of actionfor trade mark dilution. Unfortunately, the statutory languageselected by Congress created certain ambiguities, includinghow famous a trade mark had to be to merit dilution protectionunder the statute. Confusion developed as to whether a markmerely needed renown in a limited geographic area or industry—aconcept that became known as ‘niche fame’—orwhether it needed national renown to qualify as a ‘famousmark’. Key points: In 2006, Congress enacted the Trademark Dilution Revision Actand therein provided a concrete definition for a famous markthat ostensibly removed the ability to qualify for dilutionrelief where the mark was famous only within a particular niche.It was uncertain how courts that had previously favoured theniche fame theory would apply Congress's new definition. However,a district court in the Ninth Circuit, one of the strongestproponents of niche fame, recently held that niche fame is nolonger a viable theory under the Lanham Act or California statelaw as a result of the 2006 amendment. Practical significance: This decision portends that courts will fall in line with Congress'samendment and will deny dilution relief under federal law toparties whose marks are famous only in a particular geographicarea or industry. Additionally, the decision provides some guidanceand predictability as to how states may interpret the viabilityof niche fame under their respective dilution statutes in lightof Congress's 2006 amendment.  相似文献
