The contribution of Indian construction sector to the GDP is approximately 10%. Under new government policy, it is anticipated that $1000 Billion share for exclusively infrastructure segment would be completed within the next few years. Construction sector in developing country like India still depends on labor and the practice of mechanization, adopting to use of versatile construction equipment is not in force. The need for implementing new technologies and automation is essential to improve the quality, safety and efficiency. To meet the challenges ahead the construction, organizations should focus on utilization of machinery/equipment to achieve desirable results. Modern construction is characterized by the increase in utilization of equipment to accomplish numerous construction activities. The selection of construction equipment often affects the required amount of time and effort. It is therefore important for managements of construction organizations and planners to be familiar with the features of various types of equipment commonly used in construction activities. The selection of appropriate equipment is a crucial decision making process as it involves huge capital investment. The purpose of the present study is to develop a model pertaining to the factors influencing the selection of construction equipment by using interpretive structural modelling and the results indicate that productivity and safety are the important factors in selection of equipment in Indian construction organizations.
This paper presents an empirical investigation to determine the important factors influencing on adoption of biofuels from consumer’s perspective. The study designs a questionnaire in Likert scale and distributes it among 211 randomly selected people who use green products in city of Tehran, Iran. Cronbach alpha is calculated as 0.812, which is well above the acceptable level. Using principle component with Varimax rotation, the study has determined five important factors including social commitment, product usefulness, infrastructure, management approach and customer oriented, which influence the most on adaptation of biofuels.
Nowadays, trade mark is one of the most important components of the products in both consumers and producers’ perspectives. In this study, two separate but related mechanism through which the trademark is supposed to create value for customers, were investigated. Likeness/ description and functional-aesthetic benefits were taken into consideration. This research shows the positive effects of logo on customer commitment regarding the performance. Commitment reflects customers’ desire for cooperation by considering the effects of a logo. Logo will help customers easily identify and select a brand. This research proves that, from the customer's perspective, trademarks contain meaning, and thus include brief information on the struggle for marketing. In case of the purpose, this study is an applied research and in terms of data-gathering it is a descriptive – survey one. Since the population of the survey was unlimited, initial investigations indicated that 384 questionnaires should be distributed based on Morgan table. Using structural equation modeling, the survey results showed that descriptive-cognitive, functional benefits and aesthetic tendencies had significant influences on customer commitment in regards of performance.
This paper presents an empirical investigation to study the effects of different factors influencing on accomplishment of projects in Iranian oil industry. The proposed study designs a questionnaire consists of 50 questions in Likert scale with seven factors including sanctions, economy, scheduling, contractor management weaknesses, cultural/social, force majeure and contractee. The study considers the effects of these factors in three categories; namely risk of project scheduling, risk in project cost and risk in management weakness. Using structural equation modeling, the study confirms that all three factors influence on the success of oil projects. In other words, The results have indicated that budgeting as well as cost accounting is the most important factor in accomplishment of oil projects followed by weakness in management and having an appropriate scheduling.
Although job stress has become an issue of great concern over the last decades both internationally and nationally, there still remains a paucity of research in the Ghanaian insurance industry. This study therefore examined the relationship between antecedent variables (work overload, role conflict and role ambiguity) and employee job stress in the insurance industry in Ghana. Using a descriptive cross-sectional design with a survey questionnaire, 212 employees were selected to participate in the study. Pearson correlation and a two-step hierarchical regression were used to test the proposed hypotheses. Results of the analysis revealed that work overload and role conflict rather than role ambiguity were positively related to job stress. Implications for theory and practice are later discussed in the study.
