Executive function in first-episode schizophrenia
BACKGROUND: We tested the hypothesis that schizophrenia is primarily a frontostriatal disorder by examining executive function in first-episode patients. Previous studies have shown either equal decrements in many cognitive domains or specific deficits in memory. Such studies have grouped test results or have used few executive measures, thus, possibly losing information. We, therefore, measured a range of executive ability with tests known to be sensitive to frontal lobe function.
METHODS: Thirty first-episode schizophrenic patients and 30 normal volunteers, matched for age and NART IQ, were tested on computerized test of planning, spatial working memory and attentional set shifting from the Cambridge Automated Neuropsychological Test Battery. Computerized and traditional tests of memory were also administered for comparison. RESULTS: Patients were worse on all tests but the profile was non-uniform. A componential analysis indicated that the patients were characterized by a poor ability to think ahead and organize responses but an intact ability to switch attention and inhibit prepotent responses. Patients also demonstrated poor memory, especially for free recall of a story and associate learning of unrelated word pairs.
CONCLUSIONS: In contradistinction to previous studies, schizophrenic patients do have profound executive impairments at the beginning of the illness. However, these concern planning and strategy use rather than attentional set shifting, which is generally unimpaired. Previous findings in more chronic patients, of severe attentional set shifting impairment, suggest that executive cognitive deficits are progressive during the course of schizophrenia. The finding of severe mnemonic impairment at first episode suggests that cognitive deficits are not restricted to one cognitive domain
Performance of Small-Fruited Pumpkin Cultivars in Maine
A small-fruited (2-4 lb) or âpieâ type pumpkin variety trial was established in the spring of 2009 at Highmoor Farm in Monmouth, ME. Three replications of seven varieties were direct-seeded on 18 June through black plastic mulch. Plots were 18 feet long with three feet between plants and six feet between rows. All fertilizer was applied according to soil test recommendations and incorporated prior to mulch application and seeding. Fruit were harvested on 18 September. Top performing varieties in terms of yield per plot included âChuckyâ, âSmall Sugarâ, and âField Tripâ. âFall Splendorâ produced the largest fruit in the trial, followed by âWinter Luxuryâ and âMystic Plusâ. âField Tripâ and âFall Splendorâ had the highest stem quality in the trial and âField Tripâ, âMystic Plusâ and âFall Splendorâ were rated highest for exterior color and ribbing. The results of this trial suggest that âField Tripâ, âMystic Plusâ and âFall Splendorâ offer very high quality fruit with acceptable yields for pie-type pumpkins, while âChuckyâ offers acceptable fruit quality and very high yields.https://digitalcommons.library.umaine.edu/extension_ag/1000/thumbnail.jp
A-Z of postural care: how to have a good posture when sitting, standing, exercising and relaxing, a guide for teachers and parents and everyone
An A to Z of Postural Care was designed to help those who work with children with postural care needs. It has been written jointly by specialist teachers, therapists and parents of children with
physical impairments. The information provided is informed by research that explored the views of teachers and teaching assistants about their experiences of looking after children with physical impairments in mainstream primary schools in Kent. This A to Z booklet aims to give basic information and may act as a starting point for discussions with the therapy team, the childâs family and others in the school. It should link to more general awareness raising within a school of the importance of good posture for learning.
The A-Z can be used together with other POSTED training materials to provide the basis for a training programme for parents and teachers. When using/referring to this booklet please acknowledge authorship as appropriate. Details of the other POSTED training resources and publications can be found at CREATE http://create.canterbury.ac.uk/

Now the wars are over: The past, present and future of Scottish battlefields
Battlefield archaeology has provided a new way of appreciating historic battlefields. This paper provides a summary of the long history of warfare and conflict in Scotland which has given rise to a large number of battlefield sites. Recent moves to highlight the archaeological importance of these sites, in the form
of Historic Scotlandâs Battlefields Inventory are discussed, along with some of the problems associated with the preservation and management of these important
cultural sites
Exploring the interdependencies of research funders in the UK
Investment in medical research is vital to the continuing improvement of the UK's health and wealth. It is through research that we expand our understanding of disease and develop new treatments for patients. Medical research charities currently contribute over ÂŁ1 billion annually to medical research in the UK, of which over ÂŁ350 million is provided by Cancer Research UK. Many charities,
including Cancer Research UK, receive no government funding for their research
activity.
Cancer Research UK is engaged in a programme of work in order to better understand the medical research funding environment and demonstrate the importance of sustained investment. A key part of that is the Office of Health
Economicsâ (OHE) 2011 report âExploring the interdependency between public and charitable medical researchâ. This study found that there are substantial
benefits, both financial and qualitative, from the existence of a variety of funders and that reductions in the level of government financial support for medical
research are likely to have broader negative effects.
This contributed to other evidence which found that the activities and funding of the charity, public and private sectors respectively are complementary, i.e. mutually reinforcing, rather than duplicative or merely substituting for one another.
âExploring the interdependencies of research funders in the UKâ by the Office of Health Economics (OHE) and SPRU: Science and Technology Policy Research at the University of Sussex, represents a continued effort to build the evidence base around the funding of medical research.
This report uncovers the extent to which funders of cancer research are interdependent, nationally and internationally. Key figures show that two
thirds of publications acknowledging external support have relied on multiple funders, while just under half benefited from overseas funding, and almost a fifth are also supported by industry. In addition the analysis
shows that the general public would not want tax funding of cancer research to be reduced, but would not donate enough to charities to compensate for any such reduction
New Labour's communitarianisms
This article argues that communitarianism can be analysed on different levels â sociological, ethical and metaâethical â and along different dimensions â conformist/pluralist, more conditional/less conditional, progressive/conservative, prescriptive/voluntary, moral/socioeconomic and individual/corporate. We argue that New Labour's communitarianism is a response to both neo-liberalism and old social democracy. It is sociological, ethical and universalist rather than particularist on the meta-ethical level. Labour increasingly favours conditional, morally prescriptive, conservative and individual communitarianisms. This is at the expense of less conditional and redistributional socioeconomic, progressive and corporate communitarianisms. It is torn between conformist and pluralist versions of communitarianism. This bias is part of a wider shift in Labour thinking from social democracy to a liberal conservatism which celebrates the dynamic market economy and is socially conservative
The paradox of tenant empowerment: regulatory and liberatory possibilities
Tenant empowerment has traditionally been regarded as a means of realising democratic ideals: a quantitative increase in influence and control, which thereby enables "subjects" to acquire the fundamental properties of "citizens". By contrast governmentality, as derived from the work of Michel Foucault, offers a more critical appraisal of the concept of empowerment by highlighting how it is itself a mode of subjection and a means of regulating human conduct towards particular ends. Drawing on particular data about how housing governance has changed in Glasgow following its 2003 stock transfer, this paper adopts the insights of governmentality to illustrate how the political ambition of "community ownership" has been realized through the mobilization and shaping of active tenant involvement in the local decision making process. In addition, it also traces the tensions and conflict inherent in the reconfiguration of power relations post-transfer for "subjects" do not necessarily conform to the plans of those that seek to govern them
Acute effects of nicotine on visual search tasks in young adult smokers
Rationale Nicotine is known to improve performance on tests involving sustained attention and recent research suggests that nicotine may also improve performance on tests involving the strategic allocation of attention and working memory. Objectives We used measures of accuracy and response latency combined with eye-tracking techniques to examine the effects of nicotine on visual search tasks. Methods In experiment 1 smokers and non-smokers performed pop-out and serial search tasks. In experiment 2, we used a within-subject design and a more demanding search task for multiple targets. In both studies, 2-h abstinent smokers were asked to smoke one of their own cigarettes between baseline and tests. Results In experiment 1, pop-out search times were faster after nicotine, without a loss in accuracy. Similar effects were observed for serial searches, but these were significant only at a trend level. In experiment 2, nicotine facilitated a strategic change in eye movements resulting in a higher proportion of fixations on target letters. If the cigarette was smoked on the first trial (when the task was novel), nicotine additionally reduced the total number of fixations and refixations on all letters in the display. Conclusions Nicotine improves visual search performance by speeding up search time and enabling a better focus of attention on task relevant items. This appears to reflect more efficient inhibition of eye movements towards task irrelevant stimuli, and better active maintenance of task goals. When the task is novel, and therefore more difficult, nicotine lessens the need to refixate previously seen letters, suggesting an improvement in working memory
Hobsonâs choice? Constraints on accessing spaces of creative production
Successful creative production is often documented to occur in urban areas that are more likely to be diverse, a source of human capital and the site of dense interactions. These accounts chart how, historically, creative industries have clustered in areas where space was once cheap in the city centre fringe and inner city areas, often leading to the development of a creative milieu, and thereby stimulating further creative production. Historical accounts of the development of creative areas demonstrate the crucial role of accessible low-cost business premises. This article reports on the findings of a case study that investigated the location decisions of firms in selected creative industry sectors in Greater Manchester. The study found that, while creative activity remains highly concentrated in the city centre, creative space there is being squeezed and some creative production is decentralizing in order to access cheaper premises. The article argues that the location choices of creative industry firms are being constrained by the extensive city centre regeneration, with the most vulnerable firms, notably the smallest and youngest, facing a Hobsonâs choice of being able to access low-cost premises only in the periphery. This disrupts the delicate balance needed to sustain production and begs the broader question as to how the creative economy fits into the existing urban fabric, alongside the competing demands placed on space within a transforming industrial conurbation
