Specification of vertical semantic consistency rules of UML class diagram refinement using logical approach

Unified Modelling Language (UML) is the most popular modelling language use for software design in software development industries with a class diagram being the most frequently use diagram. Despite the popularity of UML, it is being affected by inconsistency problems of its diagrams at the same or different abstraction levels. Inconsistency in UML is mostly caused by existence of various views on the same system and sometimes leads to potentially conflicting system specifications. In general, syntactic consistency can be automatically checked and therefore is supported by current UML Computer-aided Software Engineering (CASE) tools. Semantic consistency problems, unlike syntactic consistency problems, there exists no specific method for specifying semantic consistency rules and constraints. Therefore, this research has specified twenty-four abstraction rules of class‟s relation semantic among any three related classes of a refined class diagram to semantically equivalent relations of two of the classes using a logical approach. This research has also formalized three vertical semantic consistency rules of a class diagram refinement identified by previous researchers using a logical approach and a set of formalized abstraction rules. The results were successfully evaluated using hotel management system and passenger list system case studies and were found to be reliable and efficient

Impact of an organization identity intervention on employees\u27 organizational commitment

This project examined the impacts of an organization identity intervention on workers’ commitment during large-scale transformational change at a financial services company. A 21-member information technology team was recruited for the study. Commitment was measured using a quantitative instrument and the events and data collected during the identity intervention were described. Participants generally enjoyed the intervention, although team members grew increasingly negative over the course of the event due to past experiences with similar interventions. Commitment was consistent across both groups and remained unchanged across the study period. The study organization is advised to assure that its leaders support and are prepared to respond to the results of any interventions conducted and take measures to nurture participants’ existing affective commitment. Continued research is needed to evaluate the impacts of the identity intervention on commitment. Such studies are advised to utilize a larger sample and to measure organizational commitment using mixed methods

Aligning enterprise risk management with business strategy and information systems

Business leaders recognise effective risk management as one of the main success drivers for enterprises. Even though the Enterprise Risk Management (ERM) concept has evolved significantly in the past years, in the aftermath of recent economic crises it became evident some of its critical challenges still need to be addressed. The review of subject literature led to a conclusion that current ERM approaches failed to protect enterprise value in turbulent and risky market conditions. Therefore, this paper aims to provide a conceptual analysis of the most common ERM practices and frameworks, in order to identify their shortcomings and areas requiring development. It is further aimed to provide guidance to business practitioners in implementing more integrated and effective Enterprise Risk Management (ERM) solutions. This research recognises the importance of aligning ERM programmes with business strategies, and with consolidated Information Systems. A “New Approach ERM Model” is developed as guidance for a successful alignment of ERM with enterprise business strategy, and for an effective adaption of Information Systems to requirements of ERM programmes. The “New Approach ERM Model” steers risk management initiatives and strategies in the same direction, and consequently allows enterprises to improve organisational effectiveness, increase shareholders value, and gain competitive advantage in the market

Service Delivery Utilizing Wireless Technology Within The Air Traffic Control Communication And Navigation Domain To Improve Positioning Awareness

Current air traffic levels around the world have pushed the enterprise architecture deployed to support air traffic management to the breaking point. Technology limitations prevent expansion of the current solutions to handle rising utilization levels without adopting radically different information delivery approaches. Meanwhile, an architectural transition would present the opportunity to support business and safety requirements that are not currently addressable. The purpose of this research paper is to create a framework for more effectively sharing positioning information utilizing improved air traffic control navigation and communication systems

A Nonprofit Model in a For-Profit World: A Closer Look at Sheltered Workshops and Sustainability as an Employee Run Business

Historically, society has tended to isolate and segregate individuals with intellectual and developmental disabilities. Despite improvements such forms of discrimination continue to be a serious social problem. On October 11, 2011, the Department of Justice began an investigation into several state’s systems of providing vocational services to individuals with intellectual and developmental disabilities. This action came about due to several states being out of compliance around Title II of the Americans with Disabilities Act (ADA). Title II of the ADA prohibits discrimination on the basis of disability for all services, programs and activities provided to the public by state and local governments. Given recent federal policy changes and directives the State of Massachusetts has created a plan developed by leaders consisting of representatives of the Association of Developmental Disabilities Providers (ADPP), The Arc of Massachusetts and the Massachusetts Department of Developmental Services (DDS) to increase opportunities for integrated employment for individuals with intellectual disabilities (ID). The intention of this plan is to phase out group employment settings otherwise known as sheltered workshops

The motivation of female college business students to manage : a study of selected college business students in certain functional specialties

The problem of this study was to investigate the motivation of college business students to manage. The purpose was to determine if there is a need for curriculum development which would provide more appropriate educational experiences for females who aspire to management positions. It was hypothesized that (1) there would be significant differences between males and females in the motivation to manage, (2) there would be significant differences among the functional specialties in the motivation to manage, and (3) there would be a significant interaction between sex differences in the motivation to manage and functional specialty. The hypotheses of this study related to overall differences; however, each subscale of the instrument used to measure the motivation to manage was analyzed separately in order to determine if significant differences existed on the individual subscales. A total of 192 subjects—109 males and 83 females--participated in the study. The functional specialties studied were general management, accounting, marketing/merchandising, and banking/finance. The motivation to manage was measured through the use of the Miner Sentence Completion Scale. Two-way analyses of variance and chi square analyses were the statistical techniques employed. A questionnaire was used to obtain both demographic and biographical data related to functional specialty choice. Six female students were interviewed in order to provide more insight into individual motivation
