Contractor-Furnished Compaction Testing: Searching for Correlations Between Potential Alternatives to the Nuclear Density Gauge in Missouri Highway Projects.
by Kevin McLain, Doug Granberg
Abstract: The Missouri Department of Transportations (MoDOT) past and present Quality Control and Quality Assurance programs for construction are examined. MoDOTs present Quality Management program along with a small number of grading projects has lowered the number of Quality Assurance (QA) soil compaction tests completed in the past two years. The Department would like to rid itself of using the Nuclear Density Gauges because of burdensome Federal regulations, required training, security and licensing fees. Linear and multiple regression analysis was performed to see if a correlation between nuclear density gauge dry densities values and Light Weight Deflectometer modulus values/ Clegg Hammer Clegg Impact Values exist. These relationships or lack thereof will determine the technology used by construction contractors to perform compaction quality control testing if MoDOT moves away from using nuclear density gauges for soil density verification.

Inter-regional patterns of life span in Pakistan: A life table analysis
by Faisal Shahzad, Jamal A. Nasir, Asif Ali
Abstract: A set of life tables for seven geographic regions of Pakistan is presented. Data from Pakistan Demographic Survey-2007 is used for the preparation of life tables. Life expectancy at birth for male is found 64.21 year in the province of Punjab, shows the highest one and 54 years for female found in the Baluchistan province which is least one. Further, urban areas of Pakistan have been seen on the forefront in terms of life expectancy in Pakistan. From the life table analysis a substantial sex differential could be discerned. The pattern of life expectancy in Baluchistan province is interesting to note, males are having higher life expectancy as compared to females.
Keywords: Keywords: Life table; Life expectancy; Mortality rate; Pakistan.
Risk Assessment of Quality Management System Failure via Analytic Hierarchy Process (AHP) and the effects on Organizational Sustainability
by Jose Pereira, Felipe Leite, Cloves Nogueira, Gabriel Oliveira
Abstract: The current dependency of industries on quality management for economic development shows the need of research into the sustainability of organizations. At present, studies on quality and organizational sustainability do not include quality management risk factors that could affect the sustainability strategies employed by different organizations. This study aims to address this gap by identifying the relevant risk factors, specifically proposing a method to identify the major risks of non-compliance to the requirements of an international quality standard (ISO 9001-2008) and to evaluate the effects on sustainability in the organizational context. The purpose of the research is to contribute to the knowledge of how organizations may be managed in order to promote organizational sustainability. To attain the research purpose, the risks of non-compliance with the elements of an international quality standard were analysed via AHP and the effects on organization sustainability were evaluated. In this study experts in quality systems were interviewed and requested to complete a survey. The six major risks identified in the application of the method are: Management not committed to quality, Inexistence of quality policy, No definition of responsibilities, Authority and communication not well defined, Inexistence of management review, Product non-conformity process not effective, Customer related process not effective. The proposed method represents an important source of motivation for firms to focus on the quality aspects of the business to improve performance in different aspects such as economic, environment and so improving organizational sustainability. The method provides managers and leaders of an organization with the required information necessary to allocate resources to address the most critical risks to enhance sustainability and reduce negative outcomes associated with unsustainable processes.

An Ant Colonial Optimization Approach for No-Wait Permutation Flow Shop Scheduling
by Ahtisham Shad Khan, Mirza Jahanzaib, Ahmad Wasim, Salman Hussain
Abstract: This research aims to address the applications of variants of Ant Colony Optimization (ACO) approach to solve no-wait flow shop scheduling problem (NW-FSSP). The most suitable ACO algorithm out of basic algorithms has been selected and modified to achieve more purified results. The algorithm was coded in Visual basic. The varied algorithm has been applied to the bench mark problems and results were compared with the results achieved previously by other researchers using different meta-heuristics. The research covers detailed steps carried out for application of basic ACO algorithms on bench mark problems, comparison of results achieved by application of basic ACO algorithms, selection of best out of basic algorithms, modification of selected basic algorithm and generation of varied ACO algorithm. The varied ACO algorithm gave reasonably good results for almost all the problems under consideration and was able to handle fairly large sized problems with far less computational time. Comparative analysis depicted that the proposed ACO Algorithm performed better than Genetic algorithm on large sized problems and better than Rajendran heuristic in almost all problems under considerations.

A conceptual framework of the relationship between Total Quality Management, Corporate Social Responsibility, innovation capability, and financial performance
by Younès EL MANZANI, Mohamed Larbi SIDMOU, Jean-Jack Cegarra
Abstract: Total Quality Management, Corporate Social Responsibility, and innovation are considered as strategic orientations allowing the achievement of a sustainable competitive advantage. However, there is a gap in the literature regarding the study of the links between these three concepts in a single analysis, the majority of researchers do not gather the study of these three concepts at once, as they do not as well link them to the financial performance. The main purpose of this conceptual paper is to examine the relationship between quality, innovation, Corporate Social Responsibility and financial performance. We are aiming to build a conceptual framework with a particular emphasis on the role that may be played by TQM practices in the development of the bidirectional link between Corporate Social Responsibility-innovation capability, and its impact on the improvement of the firms financial performance.
Keywords: Total Quality Management (TQM); Corporate Social Responsibility (CSR); innovation capability; financial performance.
The Level of Quality Teaching in Private Institutions: Comparative Study based on Students Perceptions and Expectations
by Zuhair Al-Hemyari, Ali Al-Humairi
Abstract: One of the major and ongoing goals in higher education institutions, is to satisfy students and to meet students needs. In fact, student satisfaction is a logically compound concept and multi-level issue and in order to study the level of student satisfaction in institutions and students perceptions and expectations in a quality of teaching context, several indicators have to be driven from the concept, identified and measured. In addition, the above concepts are relevant and are the most important issues; at the same time, these issues have strong influence in the sustainability of institutions and perpetuate the sustainability of institutions. One of the purposes of this article is to highlight the importance of students opinions in institutions. In particular, the paper reviews two national studies on students perceptions and expectations of the quality of teaching in private institutions: the methodologies of the two studies were discussed and the paper gave useful and simple comparisons between them. The paper determines ten common indicators between the studies - the results of the indicators are tested and compared and in general they are only average and approximately equal.
Keywords: Private Higher Education Institutions; Students’ Perceptions; Quality Teaching; indicators.
A Genetic Algorithm Based Schedule Optimisation of a Job Shop with Parallel Resources
by Ahmad Wasim, Zawar A Nawaz Bhatti, Mirza Jahanzaib, Salman Hussain
Abstract: With realization of the importance of job shops, many industrial work centres are now shifting their focus towards implementation of job shop methodology. On the other hand large throughput and just in time restrictions have augmented the requirement of additional parallel resources at various stages. This generates the scope for research on optimizing Job shop problem with parallel resources. However, research on this topic is very limited as compared to other job shop improvements. A Genetic Algorithm (GA) has been proposed in this research work which effectively finds the optimal makespan for a Job shop problem with parallel resources. The algorithm was implemented on modified benchmarks from literature and the results were compared with heuristics / methods already available in literature for solving the problem. It is shown that the proposed GA performs reasonably well when compared to the other techniques under consideration.
Keywords: Makespan; work centers; benchmarks; just in time.
