作者： luis Miguel Rodriguez Ever Torres luis Saenz Maria del Carmen Avitia guillermo Rodriguez Eduardo Herrera Carmen Julia Navarro guillermo Gonzalez luis Lozoya Damaris Acosta Technological Institute of Parral Parral Chihuahua 33850 Mexico Research Center for Advanced Materials （CIMA V） Chihuahua 31109 Mexico

Research was done with the objective of evaluating the quality of water supplied to the potable water system in Hidalgo Del Parral, which comes from two main supply sources: wells from "Valle del Verano", which provide water to the east side of the city, and the Water Treatment Plant, which receives water from different mines and supplies the west side of the city. When this plant is overcome on its capacity of treatment, a part of the water from the mines is fed directly to the northwest part of the city. The metals lead (Pb), chromium (Cr), cadmium (Cd), zinc (Zn), and arsenic (As) were analyzed by atomic absorption (AA) technique, based on the United States Environmental Protection Agency (EPA) Method 7000B (Revision 2, February 2007). The digestion process was done according to the guidelines established in Method NMX-AA-051-SCFI-2001, Analysis of Water-Determination of Metals by Atomic Absorption, developed by the National Standardization Technical Committee for Environmental Protection (Mexico). The samples were collected from the following points: 13 wells and 2 re-pumping stations of "Valle del Verano", the inlet and outlet of the Water Treatment Plant, and domestic faucets. The east side of the city, supplied by the wells of "Valle del Verano", is metal-pollution free. The water that comes from the mines contains high concentrations of As, Zn, Cd and Pb, with levels that can get to 0.12, 32.6, 0.26 and 3.5 mg/L, respectively. This water pollution generated by mining can be concluded from the high levels found in the domestic samples in which, for several points, the concentrations exceed the parameters set by the current guideline. According to the results, it is vital to set a plan of remediation for the water that comes from the mines, because there is a great risk for health in the consumption of this water.

部署公司战略是其成功的基本,因为它应当指导CEO、高管层和公司每位员工的表现。策略部署始于定义策略,这一点很重要。但是,将策略定义转化为目标、沟通和传达流程、绩效评估,以及在此过程中做出贡献的员工的持续性发展同样重要。商业环境中的此种循环过程称为绩效管理。本研究分析了中铝矿业国际公司用于管理绩效的方法或模型,并对其进行详细描述,逐步解释各个方面,例如过程的各个阶段、评估方面及其相对权重、所采用的等级量表等等。此外,本研究还解释了该公司的环境、战略和主要目标,同时深入研究了用于管理各行各业（例如技术、工业和零售公司）绩效的趋势模型,读者可以从中将绩效管理概念引入真实的商业环境。总而言之,读者将自动了解组织内部绩效管理的重要性,意识到提升绩效可以更好地帮助公司部署战略。基于SWOT分析或内部、外部因素评价矩阵等常用的支持性管理工具,本文发现中铝矿业国际可在几方面改善绩效管理流程。本文基于它们对于公司战略目标的价值和可行性,对它们进行了优先性排序,深入挖掘,并提出了实用建议和切实可行的解决方案。本文将所有的优化机会分为“绩效管理策略框架”的三方面:a)认可绩效;b)明确评估过程;c)提高员工绩效。有效实施这些举措有助于重新定义中铝矿业国际的公司战略,确立中铝矿业国际“四个基本”的概念,体现公司的主要长期目标。此外,本文还提供了其他实用工具,例如目标级联方法、一致的打分量表和透明的评估阶段。总而言之,所有改进措施都将有助于重塑绩效管理方案,帮助公司转变过去的绩效评估观念,树立培养和预测员工未来绩效的观念,确保在确定所需资源的同时成功实施长期战略。总而言之,研究者强调了公司内部文化以及将文化转化为愿景和使命的重要性,这些观念将自然地指导绩效管理,同时,本文还更关注提高绩效,而不是开发管理理念和理论。本文最后提出了一些建议,以促进评估过程中的反馈和指导,实施针对实际企业需求的精准技术解决方案,增进对预测绩效和改善个人及公司绩效的关注,所有这些策略将拥抱和促进多样性。
