PurposeThe purpose of this paper is to look at current practices and associated consumption patterns in information technology, looking at how impacts of IT, for good and ill, will be evaluated by green theory.Design/methodology/approachThe paper takes an interdisciplinary approach drawing together literatures from a variety of fields, including green theory, information systems, green economics, computing, energy studies, cultural studies, waste management, and transport research.FindingsFeedback effects that cause early replacement of software and hardware form a complex, environmentally harmful, vicious circle that (...) can appropriately be called “the upgrade treadmill”. Considering wider impacts of IT suggests that imperatives to renovate, rather than replace, hardware are stronger than narrower considerations of “green IT” would suggest, and there is a responsibility on those involved in the academic disciplines associated with training future IT professionals to try to work against the “upgrade treadmill”.Originality/valueThis paper is novel in exposing green IT to green theory. In doing so, it seeks to move consideration of green IT onto a more rounded basis. (shrink)
Global cultural homogenisation has significant consequences for our responsibility for others in distant parts of the globe. ICT gives a powerful impetus to this cultural homogenisation. There are a number of distinct elements that contribute to this.
This paper looks at citizen‐facing e‐government. It considers how the non‐discretionary nature of the citizen’s relationship with government makes citizen‐facing e‐government different from business‐consumer e‐commerce. Combined with the moral basis of the state, the paper argues that there is an obligation for the state to set an example, which should affect the design of citizen‐facing e‐government, with design‐for‐all being an appropriate philosophy. Other consequences should include a preference for open standards and a wariness of unintentional endorsement of commercial products. E‐government (...) should also offer a good level of data protection and security, and has a role in educating citizens in matters of computer security. Advantages and disadvantages that may come from e‐government adoption are considered, including a number of ways in which cost savings and increases in convenience may be achieved. There are brief discussions of questions of distribution of the benefits of e‐government adoption and of the relationship of e‐government to e‐democracy. (shrink)
We present theories of gravitation and electric potentials with exponential dependence on the reciprocal distance. In the context of this kind of electric potential we investigate the dynamics of a relativistic electron interacting with a proton.
We give a relativistic treatment to the dynamics of spherical bodies rotating at very high speed. It is found that most of the mass of a homogeneous spherical quark with Franklin rotation is due to the relativistic increase of the mass.
This paper argues that the educators' vocation, in the Arendtian sense, is to prepare and cultivate in students the love for the world – amor mundi. Educators are responsible for introducing the world to students through the conservation and preservation of human tradition and the 'realm of the past.' Thus, it requires a practice of truth-telling or parrhesia. However, this parrhesiastic activity is not explicit in Arendt. This paper also invokes Foucault's account of parrhesia to emphasize another main point of (...) this paper, i.e., Arendt's conservationist view of education implies or presupposes the practice of truth-telling. If such an idea is correct, the positioning of education becomes ambiguous. For Arendt, education is located 'in between' the realms of the pre-political and political. However, suppose this implicitness of truth-telling is proven to be correct and affirmed. In such a case, we can say that education and its main motor – educators as intellectuals/scholars have a quasi-political role in society. (shrink)
Abstract This work is about the viability domain corresponding to a model of fisheries management. The dynamic is subject of two constraints. The biological constraint ensures the stock perennity where as the economic one ensures a minimum income for the fleets. Using the mathematical concept of viability kernel, we find out a viability domain which simultaneously enables the fleets to exploit the resource, to ensure a minimum income and stock perennity.

This paper looks at various ways teleworking can be linked to surveillance in employment, making recommendations about how telework can be made more acceptable. Technological methods can allow managers to monitor the actions of teleworkers as closely as they could monitor "on site" workers, and in more detail than the same managers could traditionally. Such technological methods of surveillance or monitoring have been associated with low employee morale. For an employer to ensure health and safety may require inspections of the (...) teleworkplace. When the teleworkplace is in the home, there may be an invasion of privacy associated with such inspections, that could be perceived and resented as surveillance. A problem of telework is that teleworkers may feel isolated. Methods to counter this could be associated with further forms of surveillance, and fear of such surveillance may inhibit them from reaching their potential as methods to counter isolation. The idea that teleworking may also allow communications to be intercepted by third parties is also looked at. Some, but not all, of the issues considered are applicable, to some extent, in non-teleworked employment situations. The overall conclusion of the paper is that the potential exists for surveillance to be associated with telework. Fears of such surveillance may turn actors against telework. However, much can be done to reduce such fears. (shrink)
Objectives To conduct an independent evaluation of the first phase of the Health Foundation’s Safer Patients Initiative (SPI), and to identify the net additional effect of SPI and any differences in changes in participating and non-participating NHS hospitals. Design Mixed method evaluation involving five substudies, before and after design. Setting NHS hospitals in the United Kingdom. Participants Four hospitals (one in each country in the UK) participating in the first phase of the SPI (SPI1); 18 control hospitals. Intervention The SPI1 (...) was a compound (multi-component) organisational intervention delivered over 18 months that focused on improving the reliability of specific frontline care processes in designated clinical specialties and promoting organisational and cultural change. Results Senior staff members were knowledgeable and enthusiastic about SPI1. There was a small (0.08 points on a 5 point scale) but significant (P<0.01) effect in favour of the SPI1 hospitals in one of 11 dimensions of the staff questionnaire (organisational climate). Qualitative evidence showed only modest penetration of SPI1 at medical ward level. Although SPI1 was designed to engage staff from the bottom up, it did not usually feel like this to those working on the wards, and questions about legitimacy of some aspects of SPI1 were raised. Of the five components to identify patients at risk of deterioration—monitoring of vital signs (14 items); routine tests (three items); evidence based standards specific to certain diseases (three items); prescribing errors (multiple items from the British National Formulary); and medical history taking (11 items)—there was little net difference between control and SPI1 hospitals, except in relation to quality of monitoring of acute medical patients, which improved on average over time across all hospitals. Recording of respiratory rate increased to a greater degree in SPI1 than in control hospitals; in the second six hours after admission recording increased from 40% (93) to 69% (165) in control hospitals and from 37% (141) to 78% (296) in SPI1 hospitals (odds ratio for “difference in difference” 2.1, 99% confidence interval 1.0 to 4.3; P=0.008). Use of a formal scoring system for patients with pneumonia also increased over time (from 2% (102) to 23% (111) in control hospitals and from 2% (170) to 9% (189) in SPI1 hospitals), which favoured controls and was not significant (0.3, 0.02 to 3.4; P=0.173). There were no improvements in the proportion of prescription errors and no effects that could be attributed to SPI1 in non-targeted generic areas (such as enhanced safety culture). On some measures, the lack of effect could be because compliance was already high at baseline (such as use of steroids in over 85% of cases where indicated), but even when there was more room for improvement (such as in quality of medical history taking), there was no significant additional net effect of SPI1. There were no changes over time or between control and SPI1 hospitals in errors or rates of adverse events in patients in medical wards. Mortality increased from 11% (27) to 16% (39) among controls and decreased from 17% (63) to 13% (49) among SPI1 hospitals, but the risk adjusted difference was not significant (0.5, 0.2 to 1.4; P=0.085). Poor care was a contributing factor in four of the 178 deaths identified by review of case notes. The survey of patients showed no significant differences apart from an increase in perception of cleanliness in favour of SPI1 hospitals. Conclusions The introduction of SPI1 was associated with improvements in one of the types of clinical process studied (monitoring of vital signs) and one measure of staff perceptions of organisational climate. There was no additional effect of SPI1 on other targeted issues nor on other measures of generic organisational strengthening. (shrink)
The Charmides is among Plato's most intriguing and perplexing dialogues. The range of subjects touched or treated is extremely wide: matters logical, epistemological, moral, ethical, political, and religious. In many cases, these are discussed in a highly inconclusive and aporetic way, especially when it comes to the subject of knowledge. Finally, the dialogue is also difficult on almost every level of its expression; mock-reasonings, misunderstandings, ironies, paradoxes, and perplexities abound. As a result, the run of its many arguments, both on (...) the short and the long range, and its overall structure are not easy to discern. If a text of such a character is to be made completely accessible, a full-scale commentary is required; it is much to be regretted, therefore, that there is no commentary in which the difficulties of the Greek, the argument, and the place of the philosophical problems in the development of Plato's thought are comprehensively and coherently explained. This monograph does not aspire to that status, but makes an essential contribution towards achieving that aim (in addition to the many other works in the field, Lamb's scrupulous translation of 1927 and Bloch's penetrating study of 1973 in particular) by presenting a detailed examination of forty-two passages of which the interpretation is disputed; many more minor problems are dealt with along the way. In all matters of interpretation, special attention has been paid to defining the exact place of the passage within the run of the, often intricate, argument. The result of this attention can also be observed in an analytical 'Summary of the contents of the Charmides'. (shrink)
