    The effects of high energy particles on planetary missions

    Researchers review the background and motivation for the detailed study of the variability and uncertainty of the particle environment from a space systems planning perspective. The engineering concern raised by each environment is emphasized rather than the underlying physics of the magnetosphere or the sun. Missions now being planned span the short term range of one to three years to periods over ten years. Thus the engineering interest is beginning to stretch over periods of several solar cycles. Coincidentally, detailed measurements of the environment are now becoming available over that period of time. Both short term and long term environmental predictions are needed for proper mission planning. Short term predictions, perhaps based on solar indices, real time observations, or short term systematics, are very useful in near term planning -- launches, EVAs (extravehicular activities), coordinated observations, and experiments which require the magnetosphere to be in a certain state. Long term predictions of both average and extreme conditions are essential to mission design. Engineering considerations are many times driven by the worst case environment. Knowledge of the average conditions and their variability allows trade-off studies to be made, implementation of designs which degrade gracefully under multi-stress environments

    'It'll get worse before it gets better': Local experiences of living in a regeneration area

    The negative consequences of living in deprived neighbourhoods for residents’ quality of life are well documented. Area-based regeneration initiatives are invariably concerned with improving local quality of life over the long term. The process of regeneration, however, can itself directly result in immediate and potentially lasting negative effects for local communities. This paper discusses some of the ways in which living in an area undergoing regeneration can adversely affect inhabitants’ quality of life, including problems associated with voids, relocation, demolitions, environmental quality, complexity, funding issues, uncertainty, frustration, fear for the future and consultation fatigue. A case study approach draws examples from a deprived neighbourhood in the North East of England. The conclusion discusses some of the possible implications for future regeneration policy, including: the importance of ongoing communication between professionals and communities; the need to value local people’s experience, judgement and the contribution they can make to local decision-making processes; recognition that successful regeneration can take many years; and the implications of current UK government policy

    Swimming against the tide: a study of a neighbourhood trying to rediscover its ‘reason for being’– the case of South Bank, Redcar and Cleveland

    Many of the programmes and initiatives to regenerate deprived neighbourhoods appear to have had limited lasting impact. It has been argued that one reason for this is that we still have little real understanding of the nature and scale of the problems some communities face (Bernt, 2009). This paper attempts to add to our knowledge through close study of an area with multiple problems and a history of failed regeneration attempts. An in-depth case study undertaken to explore the current situation and future prospects of South Bank, a small neighbourhood in the North East of England, highlights transferable knowledge which may be applied to other regeneration areas. The analysis considers the nature and consequences of industrial decline; entrenched deprivation; the stigmatization of communities; the value of community consultation and the potential impact of retail-led regeneration. We question whether negative stigma attached to places can be changed and we ask what the future may hold for deprived communities now that public sector funding has largely dried up, and we consider an alternative approach: the potential impacts of private sector retail-led regeneration in the absence of public sector funding

    "I Ain't No Tea Lady": Identifying and addressing barriers to non-traditional employment, training and education from a female perspective, SOVA

    The aim of this research was to examine perceptions and experiences of accessing non-traditional Education Training and Employment (ETE) from the vantage point of disadvantaged women using innovative sampling and research techniques. The research design and strategy sought to access the participant’s views and valuable experience. Many of the women whose opinions the research was trying to elicit had never considered non-traditional ETE, in their own words it simply was 'not on their radar'. We decided to adopt a 'workshop' approach. A workshop format was designed which used fun and thought provoking exercises to promote discussion. These interactive and dynamic workshops proved successful in generating some excellent data. In total 80 women from a range of areas of disadvantage participated in the research

    Theoretical investigation of the scope of sequential ligand tuning using a bifunctional scorpionate tris(1,2,4-triazolyl)borate-based architecture

    The donor properties of a series of tripodal mixed N-donor/carbene ligands derived through sequential alkylation of hydrotris(1,2,4-triazolyl)borate have been investigated by density functional theory (DFT) methods. The structures of complexes of the form [Mo(L)(CO)3]- were optimized (L = [HB(1,2,4-triazolyl)n(1,2,4-triazol-5-ylidene)3-n]- (n = 0 – 3), hydrotris(pyrazolyl)borate, hydrotris(3,5-dimethylpyrazolyl)borate and hydrotris(imidazol-2-ylidene)borate) and nuCO frequencies for these complexes and partial charges of their Mo(CO)3 fragments were determined. Results show that ligand donation is highly tunable when compared to similar experimentally known ligands with a shift in the symmetric nuCO stretching mode of -39 cm -1 on going from the tris(1,2,4-triazolyl)borate complexes to that of the triscarbene hydrotris(1,2,4-triazol-5-ylidene) and an increase in partial charge (distributed multipole analysis) of the Mo(CO)3 fragment from -0.23 to -0.48

    Severe and Enduring Eating Disorders: Concepts and Management

    Get PDF
    The concept of severe and enduring mental illness was introduced in 1999 in order to direct resources to patients suffering from long-term serious disorders, and was suggested for eating disorders in 2009. However, the term is still restricted to patients with long-term psychosis. In this chapter, the concept of severe and enduring eating disorder (SEED) is described and its relevance to anorexia nervosa (AN) and bulimia nervosa (BN) is explored. The recovery curve for anorexia nervosa seems to follow an exponential pattern with an asymptote that approaches but does not meet the horizontal, suggesting that recovery is always possible. Symptoms of AN but not BN seem to worsen after 3 years of illness, perhaps a significant threshold. Symptoms of severe and enduring AN (SEED-AN) are debilitating and longstanding as well as potentially fatal. Symptoms of severe and enduring BN (SEED-BN) are also debilitating, especially in social adjustment. In both conditions, family difficulties are prominent. A clinical approach to SEED is described based on improving quality of life, the recovery approach, (rather than cure) for sufferers and their families is described, although full symptomatic recovery can occur at any stage and clinicians should be alert to the possibility in all patients

    Constructing and validating a scale of inquisitive curiosity

    Get PDF
    We advance the understanding of the philosophy and psychology of curiosity by operationalizing and constructing an empirical measure of Nietzsche’s conception of inquisitive curiosity, expressed by the German term Wissbegier, (“thirst for knowledge” or “need/impetus to know”) and Neugier (“curiosity” or “inquisitiveness”). First, we show that existing empirical measures of curiosity do not tap the construct of inquisitive curiosity, though they may tap related constructs such as idle curiosity and phenomenological curiosity. Next, we map the concept of inquisitive curiosity and connect it to related concepts, such as open-mindedness and intellectual humility. The bulk of the paper reports four studies: an Anglophone exploratory factor analysis, an Anglophone confirmatory factor analysis, an informant study, and a Germanophone exploratory and confirmatory factor analysis
