Land degradation and inadequate faecal sludge management are two major issues in Sub-Saharan Africa (SSA). The transformation of human excreta into soil amendments and their wide-scale adoption could improve soil health and contribute to solving the sanitation crisis in SSA. There are however perception challenges around these fertilisers because of the potentially harmful components they contain such as pathogens and heavy metals, which can be removed with appropriate treatment such as composting. A major barrier to the wide scale commercialisation of human excreta derived fertiliser (HEDF) is the unclear regulations surrounding their use. The aim of this study was to identify barriers to the use of HEDF by farmers participating in the horticultural export market with Kenya as focus area since horticultural exports are a major contributor to the country’s economy. Global GAP is the most widely adopted standard for quality assurance of horticultural crops and the use of human sewage sludge is currently not allowed on certified farms. Interviews with stakeholders along the food export chain highlighted the complex interactions that exist between them and showed that Global GAP certified farmers were not willing to use HEDF on their farms even if local regulations recognise treated sludge as a valid input to agriculture. Several countries (like the UK, Sweden, Australia and the USA) created specific certification or assurance schemes to improve public perception of biosolids. The creation of a similar assurance or certification scheme specific to fertilisers made from source-separated human excreta would be a step into formalising them as a product, establishing production procedures, limits on contaminants content as well as testing protocols. Such a certification scheme could increase the confidence of regulating bodies in HEDF and lead to their acceptance by global farming standards.  相似文献

The present study examines the dynamics of the saving, human wealth and asset pricing nexus across developed and emerging economies. We introduce two equilibrium asset pricing models in an intertemporal capital asset pricing framework, including the priced factors human wealth and market portfolio in the first framework and the saving and market portfolio in the second framework. Both asset pricing frameworks consist of two-factor, four-factor and five-factor asset pricing models. We control for size and value factors in the four-factor model and size, value and momentum factors in the five-factor model. The IV-GMM estimation and GRS test results indicate that human wealth and market portfolio for the first framework and saving and market portfolio in the second framework are primary priced factors in explaining the average returns for developed economies and the aggregate level. On the contrary, both frameworks fail to yield significant results explaining the average returns for emerging economies.  相似文献

We investigate how access to different types of resources affects the success of entrepreneurial start-up firms at early stages of development in small isolated economies by studying 12 start-ups based in New Zealand. We find that successful commercialization of innovations depends on the availability of complementary assets, and that capability-based resources, especially dynamic capabilities, have a greater impact on competitive advantage of start-ups than other intangible and tangible assets. For the start-ups in our study, alliances with partners are particularly important, and so the ability to form alliances is a key capability. Successful start-ups leverage their available resources to attract alliance partners in order to access necessary complementary resources. The start-ups in our study clearly demonstrated the ability to attract partners locally but struggled to do so internationally, thereby limiting their growth potential.  相似文献

Social capital consists of trust, collective values, and shared norms. It helps society to work efficiently and, hence, promotes knowledge accumulation and growth. This paper identifies the contribution of social capital to differences in total factor productivity among European subnational regions, but, unlike other studies, it focuses on the effects of interregional differences in social capital. To do so, the paper employs a spatial Durbin model of a social-capital extended Cobb-Douglas production function. Our results suggest that transfers of knowledge might be secondary to the presence of collectivism and human capital in knowledge-generating regions. Although knowledge can cross boundaries, an absence of skills and trust limits local growth capacity. Our estimations also suggest the presence of gravity effects emanating from social and human capital in which some regions lose against others nearby that have more abundant social and human capital.  相似文献

在已有文献的研究基础上,通过员工对企业人力资源管理情况的认知来衡量人力资源管理的有效性。本文结合中国国情,对国有企业、民营企业一线员工和人力资源员工进行调研,运用数理统计方法对调研结果进行分析,得出结论:一线员工对人力资源有效性的评价普遍低于人力资源员工,民营企业的人力资源工作比国有企业做得出色。本文结合国内情况,给出了造成这种结果的原因,并提出了相关建议。  相似文献

This article introduces the special issue that seeks to spur the debate on the challenges of managing people in organizations in Africa. The debate on HRM in Africa has proceeded with tentative steps and now clearly needs to be located firmly within the international management context. It is not the purpose of this special issue to discover or develop an over-arching model of HRM. That has been attempted elsewhere. Our purpose is to bring together the various threads that characterize the on-going debate and hopefully move towards a more specific research agenda which captures the complexity of managing on the African continent. Some of these threads include the formulation of new perspectives on HR research, finding common ground with diverse disciplines and tackling enduring problems like ethnicity and discrimination.  相似文献

The aim of this study is to contrast the existence of a significant relation between good human resource practices and business results. The empirical analysis is applied to strategies implemented by Local Development and Employment Officers (LDEOs) with regard to the management of social integration and job placement programs within the context of Local Development in Spain for both the universalist and contingent perspectives of Human Resource Management. The novelty of this study lies in the impact local development programs are having on social integration and job placement, and, in particular, the effects of project management.  相似文献
