It focuses on understanding the customer′s (both management and employees) requirements for the PAS in order to prioritize and simplify the basic elements of the appraisal system and implementation process. The improved process is defined by performance planning, counseling and evaluation with assessments for individual, team and management contributions. In addition, reducing the rating scale to three categories should facilitate a very positive evaluation process for most employees and still allow a constructive focus on those individuals that must be improved. Finally, if people come first in the TQM organization, then the personnel systems must reflect this philosophy.展开更多

Through the reorganization and analyses of the domestic academic achievements, this article chose ＂the county innovation in China new countryside construction＂ as the first level index, and ＂the three dimensional innovation＂ as the second level index. Totally four levels of indices, namely the strategy level, the mechanism level, the carrier level and the comment level, were introduced to construct the county innovation appraisal system. The further adjustment and supplement of the indices and the choices of computational method must be completed through spot investigation and case study.展开更多

In the appraisement of enterprise human resource, there is a great amount of linguistic-value information. In order to improve the reasonability of the result of appraisement of enterprise human resource, we need to study the methods for processing the linguistic-value information. In this paper, a 2-stages method is proposed for processing the linguistic-value appraisement of enterprise human resource. At the first stage, we choose the experts familiar with the related field according to the appraisement goal and problem. At the second stage, we combine the appraisement results by D-S evidence theory or LOWA operator according to the nature of linguistic variable.展开更多

A longitudinal multiple data collection technique employed involved various primary and secondary sources including site visits, literature review, observation, interviews with key personnel and group discussions. General findings of this study indicate： （1） the available coping mechanisms in smallholder farming in a climate change context and （2） the challenges faced in the actual delivery of water in terms of design, management, physical and institutional factors. The study provides pragmatic recommendations for overall improvement and performance in a local, technical and socio-economic context through evaluation of the current situation, practices and processes. An integrated approach to addressing climate change impacts should include water management, rehabilitation, complete overhaul and introduction of other relevant water systems and water saving farming techniques. Yet, ownership of these technologies by communities remains instrumental. Rural development and agricultural policies that ensure maximum and full capacity utilisation of water systems to improve rural livelihoods, mitigation and adaptation to climate change are recommended.展开更多

A comparison between such a signaling mechanism and a ＂full fair value disclosure＂ is firstly carried out, highlighting variables affecting the efficiency and the effectiveness of both information strategies. Then, recovering the traditional distinction between ＂protective disclosure＂ （hard information） and ＂informative disclosure＂ （soft information）, this paper demonstrates how the former could significantly increase the positive effects associated to an employment of an independent valuer, reaching some conclusions useful to the standard setting process.展开更多

Fatigue involvements in engineering systems are complex requiring indepth analysis and optimization of the governing phenomena. The pervasive demand for suitable solutions to this circumstance has been the greatest problem faced by the systems engineers in the quest for delivering sustainable infrastructural development. Consequently, the removal of interdisciplinary boundaries and merge of design platforms pose a great challenge for an unprepared project engineering and technology community. It is imperative to understand the mechanisms promoting fatigue occurrences for a complete model conceptualisation and analysis improvement. In this paper, the duo evaluation--linear and effective crack length measurements are clearly shown to beacon the fatigue investigation for modem project engineering and technology. The paper has also examined the airfield pavement where this concept could be very useful. Such breakthrough would require accurate fatigue simulation and modelling platforms for inbuilt reliability and prudent resources management. Amongst the benefits of the fatigue analysis is the provision of an enabling environment for the sustainable management of engineering and technology projects.展开更多
