Kinds of Lay Terms modified by Lay Selected AbstractsA stronger latent-variable methodology to actual,ideal discrepancyEUROPEAN JOURNAL OF PERSONALITY, Issue 7 2008L. Francesca Scalas Abstract We introduce a latent actual,ideal discrepancy (LAID) approach based on structural equation models (SEMs) with multiple indicators and empirically weighted variables. In Study 1, we demonstrate with simulated data, the superiority of a weighted approach to discrepancy in comparison to a classic unweighted one. In Study 2, we evaluate the effects of actual and ideal appearance on physical self-concept and self-esteem. Actual appearance contributes positively to physical self-concept and self-esteem, whereas ideal appearance contributes negatively. In support of multidimensional perspective, actual - and ideal -appearance effects on self-esteem are substantially,but not completely,mediated by physical self-concept. Whereas this pattern of results generalises across gender and age, multiple-group invariance tests show that the effect of actual appearance on physical self-concept is larger for women than for men.

Davies ABSTRACT The term ,Sprachkultur' is common in German-language academic and lay discourse, but what exactly does it mean? Is it used in the same way by trained and lay linguists? This article defines the term and traces its history, before going on to compare and contrast its use by both groups. Data taken from lay-linguistic works are analysed and two recurring motifs (i. the link between morality and linguistic usage and ii. accuracy/clarity) are discussed to see what light they throw on conceptions of language and language use. The concluding section sums up the similarities and differences between lay and academic linguists. The latter tend to concentrate on ,Sprachgebrauchskultur' whereas the former are prepared to criticise the language system as well. The stress laid by lay linguists on accuracy and the link between morality and linguistic choices reflects a ,telementational' view of language which has major shortcomings, and appears to be rooted in a world-view that equates diversity with cultural and ideological fragmentation rather than seeing it as enriching. However, the study of pronouncements by trained linguists shows that their work, too, reflects ideological assumptions about the nature of standard and other varieties of German. [source] The Haunting of Susan Lay: Servants and Mistresses in Seventeenth,Century EnglandGENDER & HISTORY, Issue 2 2002Laura Gowing At Easter 1650, Susan Lay, a servant in an Essex alehouse, saw the ghost of her mistress, who had been buried three days before. This article explores the history that lay behind her experience: of sexual relationships with both her master and his son, the births and deaths of two bastard children, and beneath it all, a relationship of antagonism, competition, and intimacy with her mistress. It uses this and other legal records to examine the relationship between women in early modern households, arguing that, while antagonisms between women are typically part of effective patriarchies, the domestic life and social structures of mid seventeenth,century England bound servants and mistresses peculiarly tightly together, giving servants licence to dream of replacing their mistresses and mistresses cause to feel threatened by their servants, and making the competitive relations between women functional to patriarchal order. It suggests, finally, that at this moment in time and in this context, seeing a ghost was the best, perhaps the only, way this servant had to tell a suppressed story and stake a claim to a household that had excluded her.

Unable to comtemplate a state beyond this loss, there came into being a crisis in subjectivity itself, and the existence of the destabilized millenium subject. This subject approached the moment by both fixating on the threshold and by disavowing what lay beyond. These strategies, and the underlying anxiety which brought them into existence, were resonated through many of the cultural representations of the time. This paper argues that it is through nachträglichkeit - a 'making sense' in retrospect of earlier disparate experiences - that we can begin to examine, contextualise and account for the phenomenon of 'millenium frenzy' which came about at the end of 1999. It constructs a reading of this moment, and of two particular filmic representations which resonate the concerns of the time, examining in the process how - from a psychoanalytic perspective - culture might be understood through its representations, and how these representations can be understood through culture. [source] Locating Responsibility: The Sphere Humanitarian Charter and Its RationaleDISASTERS, Issue 2 2004James Darcy Criticised by some as a technical initiative that neglects core principles, Sphere was seen by its originators precisely as an articulation of principle. The Humanitarian Charter was the main vehicle through which this was expressed, but its relationship to the Minimum Standards has remained a matter of uncertainty. Specifically, it was unclear in the original (1999) edition of Sphere how the concept of rights informed the Minimum Standards. The revised (2004) edition goes some way to clarifying this in the way the standards are framed, yet the link between the standards and the charter remains unclear. The concern with the quality and accountability of humanitarian assistance, which motivated the attempt to establish system-wide standards through the Sphere Project, was accompanied by a desire to establish such actions in a wider framework of legal and political responsibility. In part, this reflects the conditional nature of the undertaking that agencies make when they adopt Sphere. This aspect of the charter has been neglected, but it is fundamental to an understanding of the standards and their application. This paper considers the rationale of the Sphere Humanitarian Charter and the conceptual model that underpins it. It discusses the relationship between the charter and the Minimum Standards, and the sense in which the latter are properly called ,rights-based' (explored further in a related paper herein by Young and Taylor). The author was closely involved in the conception and drafting of the charter, and this paper attempts to convey some of the thinking that lay behind it. [source] The use and abuse of hostages in later Anglo-Saxon EnglandEARLY MEDIEVAL EUROPE, Issue 3 2006Ryan Lavelle This paper explores the use of hostages in political relations in Anglo-Saxon England, often between different ethnic groups. Although much of the evidence relates to the ninth century when hostages were used as a means of guaranteeing the peace agreements made between King Alfred and his Viking adversaries, consideration will be given here to the use of hostages in the broader context of the late Anglo-Saxon period. The paper discusses whether the significance of these arrangements lay in their projection of imperial power or in their practicality as a crude political tool whose effectiveness in maintaining an agreement lay in a tangible threat. Both of these aspects of Anglo-Saxon hostageship are examined, especially with regard to peacemaking, the extent to which it could be successful, and why. [source] Sites and sanctity: revisiting the cult of murdered and martyred Anglo-Saxon royal saintsEARLY MEDIEVAL EUROPE, Issue 1 2000Catherine Cubitt The cults of the murdered and martyred royal saints of Anglo-Saxon England have been interpreted as political in origin and this view has received widespread acceptance. This article, which discusses the cults of the kings, Oswald, Oswiu and Edwin of Northumbria, and Edward the Martyr and those of the princes, Kenelm of Mercia and Æthelred and Æthelberht of Kent, puts forward a new interpretation, suggesting that their cults originated in lay and non-élite devotion to the innocent victims of unjust and violent death, before being taken up for political and other purposes. It addresses the problem of popular religion in Anglo-Saxon England and seeks to show how these cults may be used to shed light on the beliefs of the ordinary Anglo-Saxon laity. [source] Long-term landscape evolution: linking tectonics and surface processesEARTH SURFACE PROCESSES AND LANDFORMS, Issue 3 2007Paul Bishop Abstract Research in landscape evolution over millions to tens of millions of years slowed considerably in the mid-20th century, when Davisian and other approaches to geomorphology were replaced by functional, morphometric and ultimately process-based approaches. Hack's scheme of dynamic equilibrium in landscape evolution was perhaps the major theoretical contribution to long-term landscape evolution between the 1950s and about 1990, but it essentially ,looked back' to Davis for its springboard to a viewpoint contrary to that of Davis, as did less widely known schemes, such as Crickmay's hypothesis of unequal activity. Since about 1990, the field of long-term landscape evolution has blossomed again, stimulated by the plate tectonics revolution and its re-forging of the link between tectonics and topography, and by the development of numerical models that explore the links between tectonic processes and surface processes. This numerical modelling of landscape evolution has been built around formulation of bedrock river processes and slope processes, and has mostly focused on high-elevation passive continental margins and convergent zones; these models now routinely include flexural and denudational isostasy. Major breakthroughs in analytical and geochronological techniques have been of profound relevance to all of the above. Low-temperature thermochronology, and in particular apatite fission track analysis and (U,Th)/He analysis in apatite, have enabled rates of rock uplift and denudational exhumation from relatively shallow crustal depths (up to about 4 km) to be determined directly from, in effect, rock hand specimens. In a few situations, (U,Th)/He analysis has been used to determine the antiquity of major, long-wavelength topography. Cosmogenic isotope analysis has enabled the determination of the ,ages' of bedrock and sedimentary surfaces, and/or the rates of denudation of these surfaces. These latter advances represent in some ways a ,holy grail' in geomorphology in that they enable determination of ,dates and rates' of geomorphological processes directly from rock surfaces. The increasing availability of analytical techniques such as cosmogenic isotope analysis should mean that much larger data sets become possible and lead to more sophisticated analyses, such as probability density functions (PDFs) of cosmogenic ages and even of cosmogenic isotope concentrations (CICs). PDFs of isotope concentrations must be a function of catchment area geomorphology (including tectonics) and it is at least theoretically possible to infer aspects of source area geomorphology and geomorphological processes from PDFs of CICs in sediments (,detrital CICs'). Thus it may be possible to use PDFs of detrital CICs in basin sediments as a tool to infer aspects of the sediments' source area geomorphology and tectonics, complementing the standard sedimentological textural and compositional approaches to such issues. One of the most stimulating of recent conceptual advances has followed the considerations of the relationships between tectonics, climate and surface processes and especially the recognition of the importance of denudational isostasy in driving rock uplift (i.e. in driving tectonics and crustal processes). Attention has been focused very directly on surface processes and on the ways in which they may ,drive' rock uplift and thus even influence sub-surface crustal conditions, such as pressure and temperature. Consequently, the broader geoscience communities are looking to geomorphologists to provide more detailed information on rates and processes of bedrock channel incision, as well as on catchment responses to such bedrock channel processes. More sophisticated numerical models of processes in bedrock channels and on their flanking hillslopes are required. In current numerical models of long-term evolution of hillslopes and interfluves, for example, the simple dependency on slope of both the fluvial and hillslope components of these models means that a Davisian-type of landscape evolution characterized by slope lowering is inevitably ,confirmed' by the models. In numerical modelling, the next advances will require better parameterized algorithms for hillslope processes, and more sophisticated formulations of bedrock channel incision processes, incorporating, for example, the effects of sediment shielding of the bed. Such increasing sophistication must be matched by careful assessment and testing of model outputs using pre-established criteria and tests. Confirmation by these more sophisticated Davisian-type numerical models of slope lowering under conditions of tectonic stability (no active rock uplift), and of constant slope angle and steady-state landscape under conditions of ongoing rock uplift, will indicate that the Davis and Hack models are not mutually exclusive. A Hack-type model (or a variant of it, incorporating slope adjustment to rock strength rather than to regolith strength) will apply to active settings where there is sufficient stream power and/or sediment flux for channels to incise at the rate of rock uplift. Post-orogenic settings of decreased (or zero) active rock uplift would be characterized by a Davisian scheme of declining slope angles and non-steady-state (or transient) landscapes. Such post-orogenic landscapes deserve much more attention than they have received of late, not least because the intriguing questions they pose about the preservation of ancient landscapes were hinted at in passing in the 1960s and have recently re-surfaced. As we begin to ask again some of the grand questions that lay at the heart of geomorphology in its earliest days, large-scale geomorphology is on the threshold of another ,golden' era to match that of the first half of the 20th century, when cyclical approaches underpinned virtually all geomorphological work.

Sudden death of competitive athletes is rare. However, they continue to have an impact on both the lay and medical communities. These deaths challenge the perception that trained athletes represent the healthiest segment of modern society. There is an increasing frequency of such reported deaths worldwide and the visibility of this issue is underlined by the high-profile nature of each case. Differential diagnosis between pathological and the physiologic (nonpathological) responses to high levels of physical training has become clinically more important. The purpose of this review is to highlight the main echocardiograph characteristics related to different types of training/sports participation and to highlight already recognized and newer concepts in their clinical assessment. [source] Advances in insect biotechnology for human welfareENTOMOLOGICAL RESEARCH, Issue 2008Thomas A. MILLER Abstract Biotechnology is the latest scientific breakthrough in the history of agriculture. Yet despite the promise of developing new tools for pest and disease control, transgenic organisms have encountered a mixed reception by the lay and scientific public alike. Yields are unable to keep pace with rising costs resulting in a decline in traditional farming. Switching to a new organic growing paradigm is occurring in Korea and the United States today. These new approaches ignore traditional tools that were responsible for the increased yields that support the current affluence and allowed us to protect crops while buying time to find more ecologically-friendly methods. The perception that we understand crop diseases and pests is false and those making this assumption risk destabilizing global food production. There are new pests and diseases that are very difficult to control without these traditional non-organic methods. Invasive species continue to arrive at high rates adding to the burden of farming. Global climate change is already causing changes in the pest and disease complexes and is forcing the entomologist and plant pathologist to make drastic changes to adjust to them. [source] Complete sequence of the IncP-9 TOL plasmid pWW0 from Pseudomonas putidaENVIRONMENTAL MICROBIOLOGY, Issue 12 2002Alicia Greated Summary The TOL plasmid pWW0 (117 kb) is the best studied catabolic plasmid and the archetype of the IncP-9 plasmid incompatibility group from Pseudomonas. It carries the degradative (xyl) genes for toluenes and xylenes within catabolic transposons Tn4651 and Tn4653. Analysis of the complete pWW0 nucleotide sequence revealed 148 putative open reading frames. Of these, 77 showed similarity to published sequences in the available databases predicting functions for: plasmid replication, stable maintenance and transfer; phenotypic determinants; gene regulation and expression; and transposition. All identifiable transposition functions lay within the boundaries of the 70 kb transposon Tn4653, leaving a 46 kb sector containing all the IncP-9 core functions. The replicon and stable inheritance region was very similar to the mini-replicon from IncP-9 antibiotic resistance plasmid pM3, with their Rep proteins forming a novel group of initiation proteins. pWW0 transfer functions exist as two blocks encoding putative DNA processing and mating pair formation genes, with organizational and sequence similarity to IncW plasmids. In addition to the known Tn4651 and IS1246 elements, two additional transposable elements were identified as well as several putative transposition functions, which are probably genetic remnants from previous transposition events. Genes likely to be responsible for known resistance to ultraviolet light and free radicals were identified. Other putative phenotypic functions identified included resistance to mercury and other metal ions, as well as to quaternary ammonium compounds. The complexity and size of pWW0 is largely the result of the mosaic organization of the transposable elements that it carries, rather than the backbone functions of IncP-9 plasmids. [source] No change in the structure of the brain in migraine: a voxel-based morphometric studyEUROPEAN JOURNAL OF NEUROLOGY, Issue 1 2003M. S. Matharu Migraine is a common, disabling form of primary neurovascular headache. For most of the twentieth century it was regarded as a vascular headache whose primary pathophysiology lay in the cranial vasculature. Functional brain imaging using positron emission tomography has demonstrated activation of the rostral brain stem in acute migraine. Voxel-based morphometry is a new fully automated whole brain technique that is sensitive to subtle macroscopic and mesoscopic structural differences between groups of subjects. In this study 11 patients suffering from migraine with aura (10 females, one male: 23,52 years, mean 31); 11 controls (10 females, one male: 23,52, mean 31); 17 patients with migraine without aura (16 females, one male: 24,57, mean 34); 17 controls (16 females, one male: 24,57, mean 34) were imaged with high resolution volumetric magnetic resonance imaging. There was no significant difference in global grey or white matter volumes between either patients with migraine and controls, or patients with aura and without aura. This study did not show any global or regional macroscopic structural difference between patients with migraine and controls, with migraine sufferers taken as homogenous groups. If structural changes are to be found, other methods of phenotyping migraine, such as by genotype or perhaps treatment response, may be required to resolve completely whether there is some subtle structural change in the brain of patients with migraine. [source] Renal Response to Arginine Vasopressin During the Oestrous Cycle in the Rat: Comparison of Glucose and Saline Infusion Using Physiological Doses of VasopressinEXPERIMENTAL PHYSIOLOGY, Issue 1 2002David E. Hartley The renal response to arginine vasopressin in the rat has been shown to depend on reproductive status. However there is no consensus as to when the kidney is most responsive. The varying results could depend on the protocol and the dose of hormone used. A study has been performed, with physiological doses of vasopressin, comparing the responses during infusion of hypotonic saline and glucose. After an equilibration period of 150 min, conscious rats were infused on each of the four days of the oestrous cycle with either isotonic saline (0.077 M) or 0.14 M glucose for a control period of 45 min. Vasopressin was then infused at 10-40 fmol min,1 for 1 h, followed by a recovery period of 90 min. Timed urine samples were collected for determination of volume, sodium concentration and osmolality. During the control period urine flow was greatest at oestrus and dioestrus day 2 and sodium excretion on dioestrus day 2 irrespective of the infusate. Vasopressin concentrations achieved lay within the physiological range and no difference was observed between the different days for a given dose. Infusion of vasopressin in both saline and glucose produced a dose-dependent antidiuresis, the greatest responses being seen of pro-oestrus and dioestrus day 2. It was only with the highest rate of infusion that a significant increase in sodium excretion was seen on each day of the cycle and the greatest responses were seen on pro-oestrus and dioestrus day 1 for both infusates. Thus the kidney shows the greatest response to physiological doses of vasopressin at pro-oestrus and dioestrus day 1 irrespective of the infusate employed. [source] Damage detection in an aluminium plate using outlier analysisFATIGUE & FRACTURE OF ENGINEERING MATERIALS AND STRUCTURES, Issue 8 2008D. CHETWYND ABSTRACT This work presents a damage detection study of a curved aluminium panel using the statistical technique of outlier analysis, where the structure was investigated using ultrasonic Lamb waves. These waves were generated by large custom-made piezoceramic patches and were sensed by smaller piezoceramic sensors surrounding each patch. The patches were mounted using the viscoelastic material Araldite 2027 and damage was added to the plate in the form of drilled holes and saw cuts increasing in length. Outlier analysis was successfully able to distinguish between the damaged and undamaged cases with a very high classification rate of over 99%, and was also able to approximate the direction from the actuator patch in which the damage lay. [source] Characterization and expression analysis of the aspartic protease gene family of Cynara cardunculus L.FEBS JOURNAL, Issue 10 2007Catarina Pimentel Cardosin A and cardosin B are two aspartic proteases mainly found in the pistils of cardoon Cynara cardunculus L., whose flowers are traditionally used in several Mediterranean countries in the manufacture of ewe's cheese. We have been characterizing cardosins at the biochemical, structural and molecular levels. In this study, we show that the cardoon aspartic proteases are encoded by a multigene family. The genes for cardosin A and cardosin B, as well as those for two new cardoon aspartic proteases, designated cardosin C and cardosin D, were characterized, and their expression in C. cardunculus L. was analyzed by RT-PCR. Together with cardosins, a partial clone of the cyprosin B gene was isolated, revealing that cardosin and cyprosin genes coexist in the genome of the same plant. As a first approach to understanding what dictates the flower-specific pattern of cardosin genes, the respective gene 5, regulatory sequences were fused with the reporter ,-glucuronidase and introduced into Arabidopsis thaliana. A subsequent deletion analysis of the promoter region of the cardosin A gene allowed the identification of a region of approximately 500 bp essential for gene expression in transgenic flowers. Additionally, the relevance of the leader intron of the cardosin A and B genes for gene expression was evaluated. Our data showed that the leader intron is essential for cardosin B gene expression in A. thaliana. In silico analysis revealed the presence of potential regulatory motifs that lay within the aforementioned regions and therefore might be important in the regulation of cardosin expression. [source] Comparative metal binding and genomic analysis of the avian (chicken) and mammalian metallothioneinFEBS JOURNAL, Issue 3 2006Laura Villarreal Chicken metallothionein (ckMT) is the paradigm for the study of metallothioneins (MTs) in the Aves class of vertebrates. Available literature data depict ckMT as a one-copy gene, encoding an MT protein highly similar to mammalian MT1. In contrast, the MT system in mammals consists of a four-member family exhibiting functional differentiation. This scenario prompted us to analyse the apparently distinct evolutionary patterns followed by MTs in birds and mammals, at both the functional and structural levels. Thus, in this work, the ckMT metal binding abilities towards Zn(II), Cd(II) and Cu(I) have been thoroughly revisited and then compared with those of the mammalian MT1 and MT4 isoforms, identified as zinc- and copper-thioneins, respectively. Interestingly, a new mechanism of MT dimerization is reported, on the basis of the coordinating capacity of the ckMT C-terminal histidine. Furthermore, an evolutionary study has been performed by means of in silico analyses of avian MT genes and proteins. The joint consideration of the functional and genomic data obtained questions the two features until now defining the avian MT system. Overall, in vivo and in vitro metal-binding results reveal that the Zn(II), Cd(II) and Cu(I) binding abilities of ckMT lay between those of mammalian MT1 and MT4, being closer to those of MT1 for the divalent metal ions but more similar to those of MT4 for Cu(I). This is consistent with a strong functional constraint operating on low-copy number genes that must cope with differentiating functional limitation. Finally, a second MT gene has been identified in silico in the chicken genome, ckMT2, exhibiting all the features to be considered an active coding region. The results presented here allow a new insight into the metal binding abilities of warm blooded vertebrate MTs and their evolutionary relationships. [source] Somatic Styles of the Early Middle AgesGENDER & HISTORY, Issue 3 2008Lynda L. Coon ,Somatic Styles' examines how classical modes of gender played significant roles in carving out competitive arenas between clerical and lay elites, c.600,900 CE. The paper explores the hermeneutical obstacles standing between the contemporary theorist of gender and the complex nature of the early medieval texts under scrutiny. The analysis reconstructs classicising techniques of gender deployed by early medieval churchmen, and it does so in a way that both challenges the stranglehold of the ,one-sex' model on pre-modern understandings of gender and heals the ,rupture' between the ,Ancient' and the ,Dark Age'. Finally, the essay maps early medieval somatic and gendered styles onto an architectural space where lay and consecrated bodies met , a ninth-century monastic basilica.

[source] Gas breakthrough experiments on fine-grained sedimentary rocksGEOFLUIDS (ELECTRONIC), Issue 1 2002A. Hildenbrand Abstract The capillary sealing efficiency of fine-grained sedimentary rocks has been investigated by gas breakthrough experiments on fully water saturated claystones and siltstones (Boom Clay from Belgium, Opalinus Clay from Switzerland and Tertiary mudstone from offshore Norway) of different lithological compositions. Sand contents of the samples were consistently below 12%, major clay minerals were illite and smectite. Porosities determined by mercury injection lay between 10 and 30% while specific surface areas determined by nitrogen adsorption (BET method) ranged from 20 to 48 m2 g , 1. Total organic carbon contents were below 2%. Prior to the gas breakthrough experiments the absolute (single phase) permeability (kabs) of the samples was determined by steady state flow tests with water or NaCl brine. The kabs values ranged between 3 and 550 nDarcy (3 × 10,21 and 5.5 × 10,19 m2). The maximum effective permeability to the gas-phase (keff) measured after gas breakthrough on initially water-saturated samples extended from 0.01 nDarcy (1 × 10,23 m2) up to 1100 nDarcy (1.1 × 10,18 m2). The residual differential pressures after re-imbibition of the water phase, referred to as the ,minimum capillary displacement pressures' (Pd), ranged from 0.06 to 6.7 MPa. During the re-imbibition process the effective permeability to the gas phase decreases with decreasing differential pressure. The recorded permeability/pressure data were used to derive the pore size distribution (mostly between 8 and 60 nm) and the transport porosity of the conducting pore system (10 -5,10 -2%). Correlations could be established between (i) absolute permeability coefficients and the maximum effective permeability coefficients and (ii) effective or absolute permeability coefficients and capillary sealing efficiency. No correlation was found between the capillary displacement pressures determined from gas breakthrough experiments and those derived theoretically by mercury injection.

[source] Understanding the ,epidemic' of complete tooth loss among older New ZealandersGERODONTOLOGY, Issue 2 2010Philip V. Sussex doi:10.1111/j.1741-2358.2009.00306.x Understanding the ,epidemic' of complete tooth loss among older New Zealanders Objective:, The aim of this study was to obtain a deeper understanding of the social factors driving New Zealand's historic ,epidemic of edentulism' and how they operated. Method:, In-depth, semi-structured interviews with 31 older New Zealanders were analysed using applied grounded theory. Results:, Universal factors present in the data were: (a) the way in which New Zealand society accepted and indeed encouraged edentulism without stigma for those who had a ,sub-optimal' natural dentition; (b) how the predominant patterns of dental care utilisation (symptomatic and extraction-based) were often strongly influenced by economic and social disadvantage; and (c) the way in which lay and professional worldviews relating to ,calcium theory' and dental caries were fundamental in decisions relating to the transition to edentulism. Major influences were rural isolation, the importance of professional authority and how patient-initiated transitions to edentulism were ultimately facilitated by an accommodating profession. Conclusion:, The combined effects of geography, economics, the dental care system and the professional culture of the day, in the context of contemporary (flawed) understandings of oral disease, appear to have been the key drivers. These were supported (in turn) by a widespread acceptance by the profession and society alike of the extraction/denture philosophy in dealing with oral disease. [source] Evaluating the impact of a cancer supportive care project in the community: patient and professional configurations of needHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 6 2007Kristian Pollock PhD MA PGCHE Abstract Advances in cancer care and treatment have created a new and somewhat anomalous category of patients with a diagnosis of non-curative disease who still have a considerable period of life remaining. During much of this time they may remain relatively well, without manifest need for clinical care. The responses of patients to this challenging situation are largely unknown. However, it has been assumed that because they confront a difficult experience they will need, or can benefit from, professional intervention. The implementation of pre-emptive support measures is anticipated to improve patients' resilience in coping with their illness and approaching death. This study aimed to investigate the impact of the keyworker role in a 3-year cancer supportive community care project to identify and provide for the needs of patients with a diagnosis of non-curative cancer. It was a qualitative study incorporating face-to-face interviews and focus groups with 19 healthcare professionals and 25 patients and carers from an urban East Midlands locality and a thematic analysis of qualitative interview and focus group transcripts. The project was positively evaluated by patients, carers and professionals. However, the findings raised questions about the different configuration of ,need' within the lay and professional perspectives and how this should most appropriately be addressed. In contrast to widespread professional assumptions about patients' need for counselling, many patients preferred to turn to their friends and families for support, and to adopt a stance of emotional and personal self-reliance as a strategy for coping with their predicament. The study highlights the continuing orientation of services around professional, rather than patient, agendas and the momentum towards increasing specialisation of professional roles and the medicalisation of everyday life that flows from this. [source] ,A Very Sensible Man': Imagining Fatherhood in England c.1750,1830HISTORY, Issue 319 2010JOANNE BAILEY Fathers are at once everywhere and nowhere in the historiography of eighteenth-century England. They interact with children in family history, bear authority in histories of women, gender and marriage, use the role to demonstrate virility, and the capacity for household mastery and citizenship in the history of masculinity, and are metaphors in political culture. Yet there is little sustained work on what constituted the key attributes of fatherhood before 1830. This article shows that the ideal father in the period c.1750 to 1830 was tenderly affectionate, sensitized and moved by babies; he provided hugs, material support and a protective guiding hand. Engrossed in his offspring to the exclusion of much else apart from his wife and national duties, he offered his children a moral example and instruction and possessed a deep understanding of his children's personalities. The genesis of this imagined fatherhood lay in fundamental eighteenth-century concerns about social, class, gender and familial relationships, and national strength. His form and the language used to describe him owed much to the combined forces of the culture of sensibility and of general Christian ideals antedating Evangelical revival. [source] Focal nodular hyperplasia: what are the indications for resection?HPB, Issue 4 2005Li Chun Hsee Focal nodular hyperplasia (FNH) is a benign condition of the liver that is often discovered incidentally on radiological investigation. FNH has no malignant potential, is rarely symptomatic and surgical intervention is almost never required. However, eight patients with a diagnosis of FNH associated with upper abdominal pain or rapid growth were referred for surgery. All patients had been extensively investigated for other causes of pain and had been observed for between 1 and 7 years prior to surgical referral. The FNH lesions were between 1 cm and 8 cm in diameter. One FNH lesion 7.5 cm in diameter lay in segment VII/VIII and was related to the right and middle hepatic veins. All patients were resected with immediate and lasting control of their symptoms. Based on this experience FNH should be managed in a manner similar to haemangiomas with most lesions being safe to observe. However, it should be recognized that symptomatic FNH does occur, as well as FNH behaving in an unusual fashion such as rapid growth. Both of these findings are indications for resection. [source] A temporal perspective of the computer game development processINFORMATION SYSTEMS JOURNAL, Issue 5 2009Patrick Stacey Abstract., This paper offers an insight into the games software development process from a time perspective by drawing on an in-depth study in a games development organization. The wider market for computer games now exceeds the annual global revenues of cinema. We have, however, only a limited scholarly understanding of how games studios produce games. Games projects require particular attention because their context is unique. Drawing on a case study, the paper offers a theoretical conceptualization of the development process of creative software, such as games software. We found that the process, as constituted by the interactions of developers, oscillates between two modes of practice: routinized and improvised, which sediment and flux the working rhythms in the context. This paper argues that while we may predeterminately lay down the broad stages of creative software development, the activities that constitute each stage, and the transition criteria from one to the next, may be left to the actors in the moment, to the temporality of the situation as it emerges. If all development activities are predefined, as advocated in various process models, this may leave little room for opportunity and the creative fruits that flow from opportunity, such as enhanced features, aesthetics and learning. [source] Assessment of visibility of facial wrinkle reduction by various types of observersINTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 3 2004J. H. D. M. Westerink The prime objective of many facial wrinkle-reduction treatments is to achieve visible improvement. The visibility of before/after treatment differences is therefore often part of the efficacy assessment. This paper investigates whether the background knowledge of the people acting as observers in such assessments has an impact on the results, e.g., the subjects themselves are familiar with their faces, skin professionals have much experience in judging skin quality, and thus both might be more sensitive to small changes. In a clinical study, 44 female subjects were regularly treated during a period of 12 weeks with one of three wrinkle-reduction treatments: K, L and M (placebo). Photographs were taken before treatment and after 6 and 12 weeks. Three different types of observers judged the photographs: ,Observer type I: Twenty-four lay observers were given the 0- and 6-week and the 0- and 12-week pairs of photographs of all subjects to indicate the one with the least wrinkles in a two-alternative forced-choice procedure; ,Observer type II: The subjects themselves were given the 0- and 6-week and the 0- and 12-week pairs of their own photographs (eight replications) to indicate the photograph with the least wrinkles (two-alternative forced-choice); ,Observer type III: A trained panel of skin professionals (n = 3) each gave a 9-point Fitzpatrick wrinkle-severity score for all individual 0- and 12-week photographs. It was found that the lay observers perceived the same differences as the subjects themselves: significant improvements after 12 weeks for treatment K (P < 0.0005 and P = 0.005, respectively). No visible effects were seen for treatments L and M, but, most importantly, a significant difference between treatments K and M (placebo) (P = 0.015 and P = 0.01 for independent observers and the subjects themselves, respectively). The trained panel also identified this difference between K and M (P = 0.013) in favor of K, but here it was due to a significant deterioration over time of the ,placebo-treated' wrinkles (M, P = 0.03). Thus, in conclusion, no indications were found that extra knowledge , in the form of familiarity with the own face or in the form of professional training , results in the identification of more treatments that show significantly visible wrinkle reduction. [source] Anomalous energy losses for light projectiles traversing a polyvinylformyl resin,INTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY, Issue 4-5 2001L. E. Porter Abstract Measurements of the stopping powers of the polyvinylformyl resin known as formvar for 0.67,1.75 MeV protons, 1.19,3.02 MeV alpha particles, and 3.9,10.4 MeV 7Li ions have been analyzed in terms of modified Bethe,Bloch theory for the purpose of extracting values of the dominant parameters of the formalism employed. These parameters are the target mean excitation energy and the Barkas-effect parameter, plus a single effective-charge parameter to characterize the interactions of 4He and 7Li projectiles with the target. Whereas results for the Barkas-effect parameter agreed well with the expected value of 1.4±0.1, results for the mean excitation energy lay about 20% below the value of 71.9 eV based on the assumption of linear additivity of stopping effects. Speculation as to the source of this difference is offered. © 2001 John Wiley & Sons, Inc. Int J Quantum Chem, 2001 [source] Justice and Moral Regeneration: Lessons from the Treaty of VersaillesINTERNATIONAL STUDIES REVIEW, Issue 3 2002Catherine Lu The Treaty of Versailles, which concluded World War I, aimed to establish a "peace of justice"; sadly, it only seemed to pave the way to a second, more devastating world war. What lessons about justice and reconciliation can we learn from the treaty and its apparent failure? Some scholars argue that the fault of the treaty lay in its preoccupation with retributive justice, undermining prospects for reconciliation. Rather than positing justice and reconciliation as inherently conflictual moral values or goals, both need to be conceived as part of the project of moral regeneration. Such a multidimensional project requires a certain kind of justice and reconciliation, founded on mutual respect for the humanity and equality of others. An assessment of the relationship among truth, justice, and reconciliation in the framework of moral regeneration indicates that the most grievous moral fault of the Treaty of Versailles lay in its process, which facilitated neither a truthful accounting of the war's causes and consequences, nor the affirmation of moral truths by victors or vanquished. The lack of an authoritative and public moral accounting of the Great War undermined both justice and reconciliation in international society. [source] A Social Representations Approach To The Communication Between Different Spheres: An Analysis Of The Impacts Of Two Discursive FormatsJOURNAL FOR THE THEORY OF SOCIAL BEHAVIOUR, Issue 4 2009SUSANA BATEL This paper discusses the potential of the notions of reification and consensualization as developed by the theory of social representations as analytical tools for addressing the communication between the lay and scientific spheres. Social Representations Theory started by offering an over-sharp distinction between the reified and the consensual universes of which science and common sense, respectively, were presented as paradigmatic. This paper, however, suggests that the notions of consensual and reified can be considered as describing two distinct communicative formats: reification implying the use of arguments which establish prescriptions for representations and action, and consensualization relying on arguments which recognize the heterogeneity of representation and action. We illustrate this proposal through the analysis of a case in which the expert and the lay spheres of a Lisbon neighborhood opposed each other regarding the new laws of public participation in community matters. This analysis showed how reification and consensualization can be used as discursive formats by both spheres. The implications of the use of reification and consensualization and how they may depend on several power resources and have different impacts on social change are discussed.
