Role of recognition of prior learning for emerging economies: learning from a four sector pilot project in India

Recognition of prior learning (RPL) has increasingly been recognised as a useful way to certify experience and competencies gained in the workplace informally. Particularly pertinent is RPL in the context of international migration or in economies, where system reforms seek to overcome challenges related to access to formal training and qualifications. India has the goal to skill 300 million of its growing workforce and provide them access at various levels to certification and further learning opportunities. As a part of the overall system reforms, the Government of India, jointly with the ILO, pilot tested RPL in four sectors in collaboration with the industry and built the foundation for wider replication for another 26 growth sectors by undertaking a tracer study and evaluation. This paper can empirically establish that RPL has had a positive effect on income opportunities, occupational safety, social status and openness to further learning. The paper further discusses the challenges encountered during the implementation of the RPL projects before concluding with recommendations, highlighting the aspects required for quality RPL in an emerging economy. It closes by emphasising the importance of conducting tracer studies to determine impact and the need to provide complementary training during the RPL process.

Area method analysis and thermodynamic behavior of nonmetallic micro-inclusions in casting slab of GCr15 bearing steel

The distribution and characteristics of nonmetallic micro-inclusions of GCrI5 bearing steel were explored through metallographic area method in virtue of tracer method and electronic microscope.The results show that the micro-inclusions,of which the average value is 0.032%,are mainly the compounds formed via the adsorption/aggregation of multielement deoxidized compounds and secondarily deoxidized products on tundish liquid level.The micro-inclusions of diameters from 0 to 5 μm are 92.5% in total,which basically determines the characteristics of inclusions distribution in casting slab.The inclusions of diameters more than 10 μm only account for less than 1% in total,which have little influence on steel quality.The relationship between equilibrium compositions of the first deoxidation products and molten steel compositions was also calculated based on thermodynamic theory.

高寒草原矮火绒草和紫花针茅微斑块对Rb+的吸收距离

植物微斑块是草原植被基本的空间分布形式,空白裸地上的土壤养分资源在多远距离上能够被植物吸收是一个重要问题。利用稀有元素铷（Rb）示踪方法,通过分析Rb⁺的吸收量和吸收距离,探讨青藏高原高寒草原群落群落优势种紫花针茅（Stipa purpurea）和伴生种（同时也是退化草地常见种）矮火绒草（Leontopodium nanum）对土壤养分和水分资源的吸收范围。结果表明：紫花针茅斑块对Rb⁺的平均最大吸收距离（5.6cm）约等于平均斑块间距（5.7cm）,而矮火绒草斑块平均最大吸收距离（34.2cm）远大于紫花针茅和平均斑块间距;2个物种对Rb⁺的吸收量都与斑块大小（生物量）呈极显著正相关（P<0.001）;无论吸收量还是吸收距离,矮火绒草均大于紫花针茅。这说明裸地土壤中的养分资源可以被植物微斑块吸收利用,而且大斑块对资源占有的能力也越强。

冰岛Laugaland地热田示踪试验与回灌温度模拟

开采井温度下降是热储回灌实施过程中的潜在问题之一。在冰岛Laugaland地热田研究过程中,为评价和预测回灌后热储温度的变化,采用示踪试验方法定量研究采、灌井之间的水力联系.示踪数据的解译分析表明,采、灌井之间的水力联系密切。基于示踪试验,对不同的采、灌量条件所引起的开采井温度变化进行了定量模拟。模拟结果与实测温度之间存在一定的偏差,主要原因可能是示踪试验阶段和实施回灌时热储中水动力条件存在差异所致。此外,该区的两次地震也可能在一定程度上改变了热储中水流运动模式。
