The question of whether there are laws in ecology is important for a number of reasons. If, as some have suggested, there are no ecological laws, this would seem to distinguish ecology from other branches of science, such as physics. It could also make a difference to the methodology of ecology. If there are no laws to be discovered, ecologists would seem to be in the business of merely supplying a suite of useful models. These models would need to be (...) assessed for their empirical adequacy but not for their ability to capture fundamental truths, or the like. If, on the other hand, ecology does have laws, this prompts further questions about what these laws are and why even the best candidates for ecological laws fall short of what might be expected of laws.

In the TACITUS project for using commonsense knowledge in the understanding of texts about mechanical devices and their failures, we have been developing various commonsense theories that are needed to mediate between the way we talk about the behavior of such devices and causal models of their operation. Of central importance in this effort is the axiomatization of what might be called commonsense metaphysics. This includes a number of areas that figure in virtually every domain of discourse, such as granularity, (...) scales, time, space, material, physical objects, shape, causality, functionality, and force. Our effort has been to construct core theories of each of these areas, and then to define, or at least characterize, a large number of lexical items in terms provided by the core theories. In this paper we discuss our methodological principles and describe the key ideas in the various domains we are investigating. (shrink)
Despite the long history of beliefs about the therapeutic properties of work for people with mental ill health, rarely has therapeutic work itself been a focus for historical analysis. In this article, the development of a therapeutic work ethic (1813—1979) is presented, drawing particular attention to the changing character and quality of beliefs about therapeutic work throughout time. From hospital factories to radical ‘antipsychiatric’ communities, the article reveals the myriad forms of activities that have variously been considered fit work for (...) people with mental health problems. While popular stereotypes of basket-weaving paint a hapless portrait of institutional work, a more nuanced reading of therapeutic work and its political and philosophical commitments is advanced. The article concludes by arguing that the non-linear and inherently contested development of therapeutic work is less the effect of paradigmatic shifts within the therapeutic professions, but rather evidence of a broader human struggle with work.

Humphreys and Forde (H&F) propose that greater within- category structural similarity makes living things more difficult to name. However, recent studies show that normal subjects find it easier to name living than nonliving things when these are matched across category for potential artefacts. Additionally, at the level of single pixels, visual overlap appears to be greater for nonliving things.
The emphasis on more overt managerial actions by primary school head teachers is considered, in relation to the effects of this change on their work‐styles. Methods of studying managerial work are highlighted before the outcomes of North American and Australian research on elementary school principalship are offered. The lack of systematisation and the methodological weaknesses in the British research on primary headship are highlighted, while a survey of recent research reveals the limited knowledge. It is argued that systematic study of (...) head teacher activity could be a valuable tool in refining models for head teacher development. (shrink)
Inter‐personal morals should be understood and described in the language of duties, not rights. Rights are self‐centred, duties other‐centred. Whereas duties are primarily a moral construct, rights are primarily a legal construct. There is an important distinction between the language appropriate for inter‐personal morals, and the language appropriate for the morals of the State. The first principle of the morals of the State is that the State holds its power as trustee for the people; otherwise we would face arbitrary and (...) capricious rule. In this setting it is natural and proper to speak of rights—the rights of the citizen beneficiaries against their trustee, the State. However, inter‐personal morals and the morality of the State are inter‐dependent. Without a duty‐based personal morality, the laws which the State makes will tend more and more to be oppressive and contemptuous. And the laws of the State must themselves leave room for personal moral commitment, freely entered into, to flourish. (shrink)
