Violence appears to be increasing within our society along with a disregard for property as illustrated by the recent incidents on estates in Britain. The definition of violence varies and may include deliberate self-harm (DSH), damage to property, verbal abuse, threatening behaviour and physical attacks on persons or on staff (Shader et al., 1977; Fottrell, 1980; Ruben et al., 1980; Bouras et ...

We present a number of swinging specifications with visible and/or hidden components, such as lists, sets, bags, maps, monads, streams, trees, graphs, processes, nets, classes, languages, parsers,... They provide more or less worked-out case studies and shall allow the reader to figure out the integrative power of the swinging type approach with respect to various specification and proof formal...

webπ is a recent process calculus that has been inspired by the emerging Web Services technologies. In this paper we explore the expressivity of webπ by discussing two case studies. The first case study is about the formal semantics of the transactional construct of BPEL – the scope construct. The second case study is about a standard pattern of Web Services composition – the speculative parall...

TO BE elected President of this august Society is a very great honour. However it also carries certain responsibilities and duties. The first hurdle and probably the most daunting is the presentation of a presidential address. On examining the list of presidents who have held office since I first became a member of the Ulster Medical Society thirty-one years ago I discovered, as I anticipated, ...

Preliminary. Do not distribute. In this paper, we report the results from a large-scale field experiment with bicycle messengers. We increased the messengers comission rate, their sole form of compensation by 25 percent during four weeks. We find a positive and large intertemporal elasticity for the supply of hours. In response to the wage increase, messengers work roughly 30 percent more shift...

We present a goal and belief model of emotions and on this basis we classify the emotions people feel while at work. Among “individual” emotions we distinguish the so-called primary emotions and their “families” from cognitive emotions like curiosity and boredom; among “social” emotions we include those linked to attachment, Image and Self-Image, and the Image of the Other. We describe an empir...

Practitioner involvement in evaluation, research, development, and other forms of disciplined inquiry that are small scale, local, grounded, and carried out by professionals who directly deliver those services is embraced across a wide range of professions as essential to good professional practice. However, little is known about the character, homogeneity or diversity, outcomes, motives, and p...

In this paper, we transform the age-old wisdom that societies change through generational replacement into a formalized model that allows for quantitative forecasts of such societal changes for decades into the future. Using the term “Demographic Metabolism” which was introduced by Norman Ryder 50 years ago, we show how the blend of this concept with the methods of multi-dimensional population ...

You need to look after your body when you are at work. This not only prevents you from being injured but it also prevents you from living the remainder of your life with a long-term injury. If you do get injured at work, it may reduce your ability to continue to do that job – which means you might not be able to bring the same amount of money home to support your family. Therefore, anything you...
