The Tenuous Case for Conscience
If there is any single theme that has provided the foundation of modern liberalism and has infused our more specific constitutional commitments to freedom of religion and freedom of speech, that theme is probably âfreedom of conscience.â But some observers also perceive a progressive cheapening of conscienceâ even a sort of degradation. Such criticisms suggest the need for a contemporary rethinking of conscience. When we reverently invoke âconscience,â do we have any idea what we are talking about? Or are we just exploiting a venerable theme for rhetorical purposes without any clear sense of what âconscienceâ is or why it matters? This essay addresses two questions. The first is discussed briefly: what is âconscienceâ? What do we have in mind when we say that someone acted from âconscienceâ? A second question receives more extended discussion: granted its importance to the individuals who assert it, still, why should âconscienceâ deserve special respect or accommodation from society, or from the state? That question forces us to consider the metaethical presuppositions of claims of conscience. The discussion suggests that claims to conscience may be defensible only on certain somewhat rarified moral and metaethical assumptions. The discussion further suggests that shifts in such assumptions have transformed the meaning of claims to âfreedom of conscience,â so that such claims typically now mean almost the opposite of what they meant when asserted by early champions of conscience such as Thomas More, Roger Williams, and John Locke
âYou don't understand us!â An inside perspective on adventure climbing
This paper presents a specific (insider) perspective of a small group of experienced male Scottish adventure climbers and explores through in-depth semi-structured interviews their attitudes, strategies and justifications associated with potentially high-risk climbing situations. Attention is paid to how participants feel that they are represented and viewed by others (outsiders) who do not participate in mountaineering and climbing activities. Climbers identify the significance of media, commercial and social representations of them as risk takers. The analysis explores risk as being socially constructed, with the associated assumptions being embedded in particular discourses. Climbers present themselves as rational managers of risk and provide examples of their risk-management strategies, with such characterizations being central to their identity as climbers
A modified flood severity assessment for enhanced decision support: application to the Boscastle flash flood of 2004
A modified flash flood severity assessment is presented, based on scoring a set of factors according to their potential for generating extreme catchment-scale flooding. Improvements are made to the index through incorporation of parameter uncertainties, managing data absence, and clearer graphical communication. The motive for proposing these changes is to better inform flood managers during the development of a flash flood that may require an emergency response. This modified decision-support system is demonstrated for the Boscastle flood of 2004 and other historical floods in the United Kingdom. For Boscastle, the extreme nature of the flood is underestimated, which is likely to be due to the lack of sophistication in weighting flood parameters. However, the proposed amendments are able to rapidly reflect the reliability of a catchment severity rating, which may further enhance this technique as a decision-support tool alongside radar observations of localized storms
Sex differences in Cognitive Abilities Test scores: a UK national picture
Background and aims. There is uncertainty about the extent or even existence of sex differences in the mean and variability of reasoning test scores ( Jensen, 1998; Lynn, 1994, ; Mackintosh, 1996). This paper analyses the Cognitive Abilities Test (CAT) scores of a large and representative sample of UK pupils to determine the extent of any sex differences.
Sample. A nationally representative UK sample of over 320,000 school pupils aged 11-12 years was assessed on the CAT (third edition) between September 2001 and August 2003. The CAT includes separate nationally standardized tests for verbal, quantitative, and non-verbal reasoning. The size and recency of the sample is unprecedented in research on this issue.
Methods. The sheer size of the sample ensures that any sex difference will achieve statistical significance. Therefore, effect sizes (d) and variance ratios (VR) are employed to evaluate the magnitude of sex differences in mean scores and in score variability, respectively.
Results. The mean verbal reasoning score for girls was 2.2 standard score points higher than the mean for boys, but only 0.3 standard points in favour of girls for non-verbal reasoning (NVR), and 0.7 points in favour of boys for quantitative reasoning (QR). However, for all three tests there were substantial sex differences in the standard deviation of scores, with greater variance among boys. Boys were over represented relative to girls at both the top and the bottom extremes for all tests, with the exception of the top 10% in verbal reasoning.
Conclusions. Given the small differences in means, explanations for sex differences in wider domains such examination attainment at age 16 need to look beyond conceptions of `ability'. Boys tend to be both the lowest and the highest performers in terms of their reasoning abilities, which warns against the danger of stereotyping boys as low achievers
A multiple switched beam smart antenna with beam shaping for dynamic optimisation of capacity and coverage in mobile telecommunication networks
A new low profile antenna with improved performance for satellite on-the-move communications
A novel design solution for a low-profile fullduplex Satellite-On-The-Move Communications hybrid
scanned phased array antenna for low elevation angle
coverage (down to 10°) is described. The antenna is
operated at Ku-Band. The unique louvered array element
geometry in combination with a spatial filter/ âray
bendingâ lens facilitates the shaping of the element
pattern to increase gain at low elevation angles.
Preliminary modelling results using simple ray-tracing
and 3D E simulation indicate that the desired low angle
coverage can be achieved
A low profile radiating element with nearly hemispheric coverage for satellite communications on-the-move hybrid array antenna
A novel design solution of a dual-linearly polarised Ku-band low-profile radiating element for low elevation angle coverage (down to 10° above horizon) is presented. Such an element is suitable for full-duplex Satellite Communications On-The-Move (SCOTM) hybrid scanned phased array antenna applications. Standard designed radiating elements for array applications with low profile physical structure suffer poor low elevation angle coverage as the element pattern reduces by sine of the elevation angle. The element design demonstrated in this paper features unique louvered array element geometry incorporating a spatial âray bendingâ lens facilitates the shaping of the element pattern to increase gain at low elevation angles. Preliminary modelling results using ray tracing analysis shows that the desired low angle coverage can be achieved. Currently in progress full 3D electromagnetic simulations which include the interaction between the basic radiator and the spatial lens indicates that using an ideal tilted element with novel louvered reflector in addition with proposed lens, low angular coverage can potentially be realised in a low profile structure
Nurse-friendly nutritional screening for patient benefit
Screening for undernutrition is highly important and may reduce morbidity and mortality. The Minimal Eating Observation and Nutrition Form â Version II (MEONF-II) is a nutritional screening tool specifically developed for use by nurses. Here, we describe the translation, performance and appropriateness of the MEONF-II for the UK. Following translation from Swedish to British English, the user-friendliness and appropriateness of the British MEONF-II was tested by 29 registered nurses and final year student nurses on 266 hospital inpatients. The new British MEONF-II was perceived as highly user-friendly and appropriate. They found the MEONF-II to compare favourably to other similar tools in terms of preference, usefulness and helpfulness in providing good nutritional care. Dependency in activities and poorer subjective health were associated with a higher undernutrition risk. These findings support the appropriateness of the British MEONF-II version and suggest it may act as a user-friendly facilitator towards good nutritional nursing care
A study of what helps people with Huntingtonâs disease live with their condition
Background
Huntingtonâs disease (HD) is a life-limiting neurodegenerative condition in which the onset of symptoms, generally in midlife, is characterised by cognitive decline, psychological problems and movement disorder. HD is inherited as a dominant genetic trait. Co-morbities are prevalent and include psychiatric effects such as depression, anxiety and psychosis. Death from suicide among people with HD is reported to occur four to five times more frequently than among the general population. The only treatment for HD supported by well established evidence for effectiveness is tetrabenazine for reducing chorea and one of its side effects is depression.
Aim
To identify and prioritise âwhat helps people with Huntingtonâs disease live with their conditionâ from the perspectives of people with Huntingtonâs disease, their carers, and healthcare professionals who treat them
Method
People with HD, family caregivers and health professionals generated 94 statements in answer to the question: âwhat helps people with HD live with their condition?â The participants were based in community and institutional contexts. They prioritised the statements by organising them into five levels of importance, least to most important. Finally the participants arranged the statements into groups or âclustersâ to indicate which statements seemed subjectively to each participant to âbelongâ together. Specialised âconcept mappingâ software (Ariadne Âź) was used to graphically depict the consensus among participants of how the statements were clustered and prioritised.
Results
Expert assessment and treatment for co-morbid mental health problems were the highest priority for all participants. Flexibility in the provision of care and timeliness of help provided through integrated interdisciplinary teamworking with specialist HD expertise were also high priorities. People with HD prioritised being trusted and supported to maintain independence. They placed greater value on medical treatments than caregivers or professionals, who were more concerned with care and planning for future needs in more advanced stages of the disease. Overall participants were more concerned with lessening the impact of symptoms on living with HD than with measurably reducing specific symptoms such as chorea.
Conclusions
Healthcare professionals can help people with HD live with their condition by being more proactive in identifying and treating mental health problems, which is at present an important unmet need
The field of inter-organizational relations : a jungle or an Italian garden?
Each chapter in this Handbook contains an explicit assessment of priorities for future research that would extend and deepen an understanding of IOR. Given the diversity of contributions to this volume, it is perhaps not surprising that recommendations for future research are varied. And because the three sets of contributions start from different points-empirical manifestations, theoretical and disciplinary perspectives, and thematic interests-so the recommendations, too, might be expected to lead along different paths, 'cutting' and framing future research topics in different ways. Nevertheless, as others have suggested (Brass et al. 2005) it is possible to see some points of convergence across all three parts of the Handbook. We begin our discussion of the contributions and suggestions for the future by focusing on these points of convergence. We then look in turn at the specific ideas that emerge from, and relate to, the specific framings of each of the parts. Finally, we draw together insights about methodological issues
