The term "sustainability" has entered the lexicon of many academic disciplines and fields of professional practice, but to date does not appear to have been seriously consid ered within the systems community unless, perhaps, under other guises. Within the wider community there is no consensus around what sustainability means with some authors identifying 70 to 100 definitions of the term. Some see sustainability as the precise and quantifiable outcomes of biological systems whilst others see it in terms of processes rele vant to personal and organizational change with the potential to effect changes in our rela tionships with out environments. Internationally it has been increasingly used in relation to the term "sustainable development"--a term popularised by the Brundland Commis of definitions sion's report in 1987 entitled "Our Common Future. " Despite this diversity and polarised perception on its utility, unlike many other popular terms, it has not had its time and subsided quietly from our language. It is therefore timely for the systems com munity to explore the relationship between systems and sustainability in a range of con texts. Participants in this, the 5th International Conference of the United Kingdom Systems Society (UKSS), have been invited to reflect critically on the contribution of sys tems thinking and action to sustainability-to the sustainability of personal relationships, the organizations in which live and work, and our "natural" environment."

This book deals with the fundamentals of specification writing and management. It is useful for anyone concerned with the preparation of standards in a world that is shrinking due to improvement in communication and where many specifications have to hold clarity when translated into other languages.

The fourth edition of Object- Oriented Systems Analysis and Design has been revised and updated to reflect the most up-to-date approaches to information systems development. Still a best-seller in its field, Bennett's, McRobb's and Farmer's text remains a key teaching resource for Systems Analysis and Design courses at both undergraduate and postgraduate level. The book provides a clear, practical framework for development that uses all the major techniques from UML 2.2. It follows an iterative and incremental approach based on the industry-standard Unified Process, placing systems analysis and design in the context of the whole systems lifestyle. Structured in four parts, the first provides the background to information systems analysis and design and to object-orientation. The second part focuses on the activities of requirements gathering and systems analysis, as well as the basic notation of UML. Part three covers the activities of systems architecture and design, and UML notation for object design, and the book concludes with the implementation of systems and the issues of how the systems life cycle is organized and how reusable components can be developed.

Collection of CGI-animated features following the adventures of everyone's favourite chipmunk brothers. In 'Alvin and the Chipmunks' (2007) Alvin, Simon and Theodore (voices of Justin Long, Matthew Gray Gubler and Jesse McCartney) are discovered and adopted by struggling songwriter Dave Seville (Jason Lee). When Dave finds them singing some of his songs, the foursome decide to join forces and embark on a career in the music business. When success beckons however, unscrupulous record company boss Ian Hawke (David Cross) decides that he could make a lot more money from the boys if Dave was out of the picture. In 'Alvin and the Chipmunks: The Squeakquel' (2009), when Alvin, Simon and Theodore are forced to put aside their music superstardom and go back to school, they are given the challenge of saving the school's music department by winning the $25,000 prize in a battle of the bands. But the trio unexpectedly meet their match in three singing female chipmunks known as The Chipettes: Brittany, Eleanor and Jeanette (voices of Anna Faris, Amy Poehler and Christina Applegate). Romantic and musical sparks fly in the face-off that ensues. In 'Alvin and the Chipmunks: Chipwrecked' (2011) Alvin, Simon and Theodore take to the high seas. When their luxury liner becomes grounded on a remote island during a tropical cruise, the boys soon discover their secluded paradise is not as deserted as it seems. As they struggle to contend with the heat, the insects and the close proximity to one another, the chipmunks begin to develop a few strange personality traits. In 'Alvin and the Chipmunks: Road Chip' (2015), when Dave reveals that he is travelling to Miami to propose to his girlfriend Shira (Kimberly Williams-Paisley), the three chipmunks fear for their future, especially as Shira's teenage son Miles (Josh Green) has taken an instant disliking to Dave's furry friends. As the trio put their heads together to try to break up the happy couple, they find an unlikely ally in Miles. With the common ground they share - wanting to break up the engagement - Alvin, Simon, Theodore and Miles do all they can to create a barrier between Dave and Shira.
