Programmers practicing software development have long realized that reusability is an important area of concern-it is an attribute of quality, which depicts the extent to which a module can be used again in different applications with slight modification.Software professionals often adopt the Module-oriented Approach (MOA) and / or the Object-Oriented Approach (OOA) to develop reusable software. However, these approaches do not address crosscutting concerns (such as logging, security etc.), which are scattered throughout the code and which if poorly done adversely affect reusability and maintainability.Readers may note that "reusability" is a quality attribute whose assessment remains quite underexplored. This paper discusses the importance of reusability as a quality attribute and its essence in Aspect-Oriented Systems.
Maintenance is the important phase in software development lifecycle which initiates after the software has been deployed for use. Reusability is an important area of concern which depicts the extent to which a module can be used again in different applications with slight or no modification. Maintainability is one of the contributing factors for assessing Reusability. So, assessment of Reusability is preferred over Maintainability. This paper has been split into Introduction, Role of Maintainability, Role of reusability and conclusion. In the introduction section the concept that how the software evolves has been discussed. The second section focuses on the Role ofMaintainability. The third second emphasizes on the Role of Reusability within the domains of Object-Oriented Programming and Aspect-Oriented Programming. In the last section we have concluded that assessment of Reusability must be given more preference over the assessment of Maintainability.
The green Practices have established a lot of implications in modern business. Green specifies purity through fairness in price, quality and worth in dealings. Green practices focus on producing and promoting products to satisfy the wants and needs of the consumers. Automobile industry is beginning to adopt green practices to get maximum benefit by brand enhancement, long-term cost savings, improved compliance with regulations and to appeal to higher investor interest and talent. But there is still scope and need to participate more in green technologies. In such a situation, the automobile industry is facing dual pressure i.e., to maintain the financial performance of the firm in the long run and to save the environment at the same time. This paper is an effort to analyze the impact of green practices adopted on the financial performance of the automobile companies in India. For this study a structured questionnaire is administered to a sample of 285 supply managers of the automobile Industry in India. Structural equation modelling method is used to analyze the data. In the results, it was found that four factors i.e., Integrated Environmental Management, Eco design, Technology Integration and green marketing had positive and significant influence on financial performance of the automobile companies. However, Pollution Prevention and Customer Oriented were found to have no significant influence on automobile companies' financial performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
