新疆农业存在的问题及几点政策建议

随着新疆经济的发展农业产业有了根本性的结构调整,近几年新疆农业从单纯的粮食、棉花生产转化为多元化农产品生产.但以往的经济制度在市场开发和变化中难以加快农民进入市场的步伐.本文从新疆地域特色角度分析新疆农村面临的问题,并提出了相应的对策建议.     

在近岸采油装置上实施集成风险检查系统

介绍中东国家把集成风险检查和检查系统用于近岸油田装置。根据详细的风险检查分析和过去的检查记录,对所选择的设备采用无损检测技术实施检查。资产数据、检查记录和有关文件都集中保存在计算机系统中。这样有能力保管和查看不同种类的文件和图样。这个系统能生成和监管维修和检查工作单,并能与企业其他系统进行交流。有一个知识数据库用于资产整合活动,与MS Excel的输入/输出功能进行数据交换也更加方便。     

煤炭企业工程技术人员劳动效果的评价

在生产的规模和复杂程度日益增加,经济管理机构日趋完善的情况下,提高工程技术人员的劳动效果具有很大的现实意义。为此,必须保证进一步完善生产管理方式和方法,提高工程技术人员劳动效果,采用先进的劳动组织和以最终劳动成果为基础的先进的奖励制度。在制定有关工程技术人员劳动效果评价的方法原理和建议时,要解决如下任务:分析企业现有确定劳动效果的方法原理,研究决定工程技术人员劳

Program Evaluation and Review Technique (PERT) in Construction Schedule Risk Assessment

Construction project scheduling is one of the most critical factors for project success measurement.Not only for the project planning but for construction process management,the scheduling is the basic tool for communication between the owner and the project manager.By developing the schedule before the project starts,the owner knows in advance that the expected timeline of the project.By preparing construction process scheduling,the owner and general contractor can better manage the subcontractors,sub-trades progress,materials storage and deliveries,labors schedule and equipment set up which will eventually save time,money and hassle.Basically,Critical Path Method(CPM) is commonly used in the construction industry.CPM is a deterministic method that assumes that through the network,there is at least one path that determines the project duration and that the path is the critical path.CPM does not consider the uncertainty in the activities;rather it assumes that each activity can be finished in the given situation.Program Evaluation and Review Technique(PERT) is a stochastic technique which is based on the assumption that the duration of a single activity can be described by a probability density function.PERT takes into account the uncertainty during the construction process and has been created out of the need to plan,schedule and control complex projects with many uncertainties.The PERT approach is stated in some books and papers,but there is no deep investigation on the application in the schedule risk assessment.This paper investigates the PERT work process and takes a valuable try on the construction schedule risk assessment by using case studies.The utilization in the estimate the construction liquidated damage with the uncertainties is performed,which also can be used in the insurance company to calculate the insurance premium.     

俄罗斯的基础设施PPP模式现状与前景

基础设施的发展,毫无疑问是国家发展的基本方向条件。国家-私营合作,是一种方便的合作机制。在这种机制下,政府可以用较少的资金或政府不耗费自己的资金来发展基础设施建设。对于俄罗斯来说,运用国家-私营的合作方式,成为发展本国基础设施建设的新方式。但如果缺少完善的法律制度,将会阻碍发展的进程。     

毕业之后

最近,我以前的一些学生开始应付毕业后的现实生活问题。每次听到他们的感叹,都会让我想起当我开始找第一份正式工作时,我的母亲对我说的话,＂艰苦的工作是不容易的,但容易的工作是不好找的。＂如今,与很多中国学生不同,当我听到这些话的时候,已经有非常多艰苦工作的经验。     

如何更好地理解石油市场

石油价格在过去六个月暴跌引发了广泛的讨论,其中不乏阴谋论。虽然这些解释都非常有创意而且有趣,但我们认为只有通过分析供给、需求、经济表现以及成本竞争力,才能更好地分析形势。很多人预测到强劲的供给增长,但我们认为最意外的因素是需求不足——每天的需求量低于某些预测60万桶左右。石油供给连续三年增长,这主要来自北美。但到2014年中,全球需求疲软已经非常明显。一旦需求供给相互作用,石     

Does reputation of sponsors matter in IPO? Evidence from Hong Kong

Contrary to other markets where underwriters perform a combined role of underwriting and sponsoring in an Initial Public Offering (IPO), IPO issuers in Hong Kong must appoint at least one sponsor in addition to the underwriters. The splitting of the single role of underwriters into two separate ones offers an ideal setting to disentangle the effects of the two roles and to examine which of the two roles—sponsor or underwriter—is more important in explaining IPO underpricing and initial volatility in the Hong Kong equity market. Interestingly, our findings provide supportive evidence that the sponsor reputation does matter in an IPO and it is even more significant than the underwriter reputation in explaining the IPO underpricing phenomenon. Given the recent high-tech fervor, our research goes deeper to examine specifically the role of sponsors on high-tech firms, with results indicating that the reliance on sponsors is higher for traditional issuers than for technology firms. We further discover that sponsors and underwriters are playing substitution roles rather than complementary roles. In order to examine the regulatory policy impact, our research also compares the role of IPO sponsors before and after the launch of the new sponsor regulatory regime in 2013. The empirical findings lend support to our argument that after the launch of the new regulations, public awareness of sponsors is raised, respect towards more reputable sponsor increases, and thus, the role of sponsors becomes more important than before.
