To improve the fault detection power of the partial least square (PLS) method for quality control, a new QRPV statistic is proposed in terms of the VP (variable importance in projection) indices of monitored process variables, which is significantly advanced over and different from the conventional Q statistic. QRPV is calculated only by the residuals of the remarkable process variables (RPVs). Therefore, it is the dominant relation between quality and RPV not all process variables (as in the case of the conventional PLS) that is monitored by this new VP-PLS (VPLS) method. The combination of QRPV and T2 statistics is applied to the quality and cost control of the Tennessee Eastman (TE) process, and weak faults can be detected as quickly as possible. Consequently, the product quality of TE process is guaranteed and operation costs are reduced.展开更多

Our present day workforce is made up of a diverse group of people： Matures, also known as Veterans （age 55＋）, Baby Boomers （age 45-54）, Generation X （age 35-44） and Generation Y also known as Millennial （age 18-34）. The differences and challenges among these groups will be evident when reviewing recognition and praise, managerial styles, subordinate responses to generational leadership. Companies are stepping back and looking more holistically at how to develop programs and deploy technology that will speak to four distinct generations in the workforce （Sprague, 2008）. Each generation has their own definition of work ethic, responsibility, and performance. The best way to deal with the multi-generations is coming up with ways that make everybody feel like they are members of a team, thus helping them to learn how to develop a better way of communication than what exists between them now. If everybody is a part of a team, then they are all sharing the benefits that the other generations can bring to the table, making them a strong entity. Matures and boomers can become mentors to the X and Y＇s, and the X and Y＇s can then share and impart their knowledge of technology to the Matures and boomers. Companies in today＇s workplace must learn a better way to understand the values of the four generations, for it is very important in understanding and guiding these people in the workplace. Without this proper understanding, the guidance and alliance that managers are hoping to achieve will be even longer in the making and then one, possibly two, whole generations will be gone from the workforce and their knowledge and skill gone as well.展开更多

The drivers for this application of engineering design to infrastructure in an industrial setting where cost and time to market are vital were to spread best practice, and to gain experience in dealing with the regulatory authorities according to ISO 14000. Therefore, the aim of this study was to evaluate the performance of the industrial wastewater treatment plant of the Hilla Textile Factories, to find an appropriate method of treating the industrial wastewater so as to render it fit for reuse or safe to be disposed of as stipulated by the Iraqi laws on effluent disposal. The removal efficiencies of the different parameters used to describe water quality was low. It was found that the removal efficiency of COD （Chemical Oxygen Demand） was 20-21%, that of BOD （Biochemical Oxygen Demand） was 17-30% and that of TSS （Total Suspended Solids） was 27-31%. The quality of the effluent was not in line with those of either the Iraqi or American standards.展开更多

This complex, during its almost 100 years of operation, has undergone significant modifications and enhancements mainly due to technological changes driven by the replacement of steam traction by electric traction, and then by diesel-electric traction. Despite this, the complex maintained an impressive architectural consistency. Unfortunately, most of the buildings of this complex are unused and in disrepair, being the target of invasions, vandalism and theft of materials that if not stopped will cause irreparable damage to its structure and to the local ambience. The question that appears most urgent, therefore, is to seek ways to repossess this group of workshops in order to meet the current demands of urban development without losing the characteristics which form its architectural and urban identity in a city in accelerated mutation.展开更多

The technological progress mode has already been changed from technology import to technological innovation stage at this time. In order to encourage innovations, we must develop venture capital in a more effective manner. The national conditions have determined the technology import of China, which must start with a high points, this is the most important condition of target to choose. The venture capital of China in system transitional period should use U.S.A.＇s experience for reference even more on the capital source to pay close attention to the capital sources of the government and bank. Once the government guides and starts the market, the folk capital will show the natural instinct of the capital automatically Risk investment is the embodiment capitalized personality spirit, in order to dispose such ambitious culture. We need the reform of the system as well as dispose risk investor＇s stratum at present.展开更多

This role has elevated the industry as a major stakeholder in the political, socio-cultural, and economic development of the people. This essential role, however, has come under serious threat following the emergence of the Digital Age, changing social trends, and a global economy that is in distress. This is the main reason this paper investigates the survival strategies adopted by the US print media industry to deal with the decline and see how the Nigerian print media industry that is facing similar decline can benefit from the strategies. The method of study is qualitative. We gathered data through in-depth interviews and on-site observation of the operations of the selected media organizations. We also reviewed literature provided by the media firms and the ones that are already in the public domain. Our findings confirm recent projections that the American and Nigerian media industries are truly facing economics of decline and that the Nigerian industry is worst hit. The study identified some of the strategies adopted by the American print media industry to deal with the economic recession to include introduction of online editions, use of pay wall, free online views, Search Engine Optimization, Micro-funding, etc. After thorough interrogation of the literature and results, we conclude that the Nigerian print media industry could apply similar strategies used in the US to address its own negative economic situation. We also recommend an upgrade in the media training curricula to address some of these concerns effectively leading to the emergence of ＂Media Entrepreneurship＂ as a course in Communication/Media Departments in Nigerian universities.展开更多

Drawing upon the archival records and publications of the American Federation of Teachers and National Education Association, the following paper argues that the ideological inclinations of union leaders hindered their efforts to protect K-12 public school teachers. The attacks on academic freedom rights during the McCarthy era would thus have implications for years to come in regard to the ability of K-12 teachers to exercise their intellectual autonomy.展开更多

S. is at the leading position in the division of labor by global value chains. The empirical evidence reveals that more international outsourcing, there will be more detailed division of labor, and the industry unit production time and production cost will show more declining trend year by year. This is consistent with that the global value chains and the outsourcing play more and more important roles in the international division of labor and economic growth in both developed and developing countries, and helps explain the integration of workforce across countries in the global value chains.展开更多
