| 1 | 学历与一生的收入:德国最新的有关调查统计(上)显示文摘教育是一项耗费时间、精力和财力的投资。如果考虑劳动力市场以后给与的回报,这种投资是否值得?我们运用标准的净现值法,以德国当前的居民年龄与收入状况为基础,利用2011—2013年德国微观人口普查中超过100万人的数据,对不同受教育程度人群进行分类并计算他们之间终生收入的差异。研究结果表明,在整个职业生涯中,每一个较高的学历都会带来多出22%到64%的收入。但是,地域、性别,特别是职业培训和大学教育的不同专业也是影响收入差距的重要因素,例如医学和社会工作之间的差异就很大。 | Marc Piopiunik Franziska Kugler Ludger Wβmann 陈颖 | 2017 | 应用型高等教育研究2017，2，4： | 2 |
| 2 | Economic Assessment and Review of Waterless Fracturing Technologies in Shale Resource Development: A Case Study显示文摘Our database tracking of USA water usage per well indicates that traditionally shale operators have been using, on average 3 to 6 million gallons of water; even up to 8 million for the entire life cycle of the well based on its suitability for re-fracturing to stimulate their long and lateral horizontal wells. According to our data, sourcing, storage, transportation, treatment, and disposal of this large volume of water could account for up to 10% of overall drilling and completion costs. With increasingly stringent regulations governing the use of fresh water and growing challenges associated with storage and use of produced and flowback water in hydraulic fracturing, finding alternative sources of fracturing fluid is already a hot debate among both the scientific community and industry experts. On the other hand, waterless fracturing technology providers claim their technology can solve the concerns of water availability for shale development. This study reviews high-level technical issues and opportunities in this challenging and growing market and evaluates key economic drivers behind water management practices such as waterless fracturing technologies, based on a given shale gas play in the United States and experience gained in Canada. Water costs are analyzed under a variety of scenarios with and without the use of(fresh) water. The results are complemented by surveys from several oil and gas operators. Our economic analysis shows that fresh water usage offers the greatest economic return. In regions where water sourcing is a challenge, however, the short-term economic advantage of using non-fresh water-based fracturing outweighs the capital costs required by waterless fracturing methods. Until waterless methods are cost competitive, recycled water usage with low treatment offers a similar net present value(NPV) to that of sourcing freshwater via truck, for instance. | Iman Oraki Kohshou Reza Barati Meaghan Cassey Yorro Tim Leshchyshyn Adebola T.
