In patients with schizophrenia, distributed abnormalities are observed in grey matter volume. A recent hypothesis posits that these distributed changes are indicative of a plastic reorganisation process occurring in response to a functional defect in neuronal information transmission. We investigated the structural covariance across various brain regions in early-stage schizophrenia to determine if indeed the observed patterns of volumetric loss conform to a coordinated pattern of structural reorganisation. Structural magnetic resonance imaging scans were obtained from 40 healthy adults and 41 age, gender and parental socioeconomic status matched patients with schizophrenia. Volumes of grey matter tissue were estimated at the regional level across 90 atlas-based parcellations. Group-level structural covariance was studied using a graph theoretical framework. Patients had distributed reduction in grey matter volume, with high degree of localised covariance (clustering) compared with controls. Patients with schizophrenia had reduced centrality of anterior cingulate and insula but increased centrality of the fusiform cortex, compared with controls. Simulating targeted removal of highly central nodes resulted in significant loss of the overall covariance patterns in patients compared with controls. Regional volumetric deficits in schizophrenia are not a result of random, mutually independent processes. Our observations support the occurrence of a spatially interconnected reorganisation with the systematic de-escalation of conventional 'hub' regions. This raises the question of whether the morphological architecture in schizophrenia is primed for compensatory functions, albeit with a high risk of inefficiency.

Long term reshaping of language, sensory, and motor maps after glioma resection: a new parameter to integrate in the surgical strategy

Objectives: To describe cortical reorganisation and the effects of glioma infiltration on local brain function in three patients who underwent two operations 12–24 months apart. Methods: Three patients who had no neurological deficit underwent two operations for low grade glioma, located in functionally important brain regions. During each operation, local brain function was characterised by electrical mapping and awake craniotomy. Results: Language or sensorimotor areas had been invaded by the tumour at the time of the first operation, leading to incomplete glioma removal in all cases. Because of a tumour recurrence, the patients were reoperated on between 12 and 24 months later. Functional reorganisation of the language, sensory, and motor maps was detected by electrical stimulation of the brain, and this allowed total glioma removal without neurological sequelae. Conclusions: These findings show that surgical resection of a glioma can lead to functional reorganisation in the peritumorous and infiltrated brain. It may be that this reorganisation is directly or indirectly caused by the surgical procedure. If this hypothesis is confirmed by other studies, the use of such brain plasticity potential could be used when planning surgical options in some patients with low grade glioma. Such a strategy could extend the limits of tumour resection in gliomas involving eloquent brain areas without causing permanent morbidity. PMID:11909913

This study focuses on employees' experience of occupational health in a radiology department within a Swedish university hospital during years of continual reorganisations. This department's stable personal health trends in terms of self-rated mental health and sick-leave rates diverged from the general trends of deteriorating working conditions in the hospital. The aim was to identify dimensions of working conditions as positive determinants contributing to occupational health in a department of radiology undergoing continual reorganisations. Open-ended interviews with twelve employees were transcribed and analyzed using content-analysis. The employees experienced their new stimulating working tasks and a supporting organizational climate as important contributors to the healthy work condition. The positive effects of handling new technical challenges and the positive organisational climate, which were characterized by mutual trust, as well as work-confidence and respect for each others' competence, seem to function as buffering factors, balancing the negative effects of parallel downsizing and restructuring processes.

Primary writing tremor (PWT) is a task-specific tremor of uncertain origin. There has been debate as to whether PWT represents a variant of essential tremor or a tremulous form of focal dystonia related to writer's cramp. In writer's cramp there is evidence of changes in intracortical inhibition (ICI), as well as cortical motor reorganisation. To study corticomotor organisation and short-latency ICI in a patient with typical task-specific PWT. Transcranial magnetic stimulation mapping of the corticomotor representation of the hand and studies of ICI using paired-pulse stimulation were performed in a 47-year-old right-handed woman with a pure task-specific writing tremor. The motor maps for the hand were displaced posteriorly on both sides and reverted to a normal position after treatment with botulinum toxin. Short-latency ICI was reduced for the dominant hand. The findings indicate reorganisation and disinhibition of the corticomotor projection to the hand and point to the participation of cortical centres in the origin of PWT.

Revolutionising landscapes: Hydroelectricity and the heavy industrialisation of society and environment in the Comte de Beauharnois, 1927--1948

Pelletier, Louis-Raphael

This dissertation analyses the rapid industrialisation of the rural Comte de Beauharnois and the adjacent stretch of the Fleuve Saint-Laurent owing to the construction, between 1929 and 1948, of a gigantic canal for hydroelectricity production and navigation by an electricity corporation called the Beauharnois Light Heat and Power (BLH&P). Using principally the archives of the BLH&P---especially its complaints files and its rich photographic record---this thesis argues that this process exemplifies the finance capitalist reorganisation of the society and ecosystems of the Canadian province of Quebec from the 19th century to the Great Depression. In keeping with recent work in environmental history, the transformation of rural landscapes and a river for heavy industry is described as an important dimension of a revolution in modes of production. More specifically, I argue that, in the case under study, the finance-capitalist reorganisation of Quebec revolved around two central and explicit projects, one social and the other environmental: the grouping of most individuals in an industrial working class without control over the means of production and the reorganisation of rural landscapes into reservoirs of modern energy and industrial natural resources.

The English health system experienced a large-scale reorganisation in April 2013. A national tri-partite delivery framework involving the Department of Health, NHS England and Public Health England was agreed and a new local operational model applied. Evidence about how health system re-organisations affect constituent public health programmes is sparse and focused on low and middle income countries. We conducted an in-depth analysis of how the English immunisation programme adapted to the April 2013 health system reorganisation, and what facilitated or hindered the delivery of immunisation services in this context. A qualitative case study methodology involving interviews and observations at national and local level was applied. Three sites were selected to represent different localities, varying levels of immunisation coverage and a range of changes in governance. Study participants included 19 national decision-makers and 56 local implementers. Two rounds of interviews and observations (immunisation board/committee meetings) occurred between December 2014 and June 2015, and September and December 2015. Interviews were audio recorded and transcribed verbatim and written accounts of observed events compiled. Data was imported into NVIVO 10 and analysed thematically. The new immunisation programme in the new health system was described as fragmented, and significant effort was expended to regroup. National tripartite arrangements required joint working and accountability; a shift from the simpler hierarchical pre-reform structure, typical of many public health programmes. New local inter-organisational arrangements resulted in ambiguity about organisational responsibilities and hindered data-sharing. Whilst making immunisation managers responsible for larger areas supported equitable resource distribution and strengthened service commissioning, it also reduced their ability to apply clinical expertise, support and evaluate immunisation providers' performance. Partnership working helped staff adapt, but the complexity of the health system hindered the development of consistent approaches for training and service evaluation. The April 2013 health system reorganisation in England resulted in significant fragmentation in the way the immunisation programme was delivered. Some of this was a temporary by-product of organisational change, other more persistent challenges were intrinsic to the complex architecture of the new health system. Partnership working helped immunisation leaders and implementers reconnect and now the challenge is to assess how inter-agency collaboration can be strengthened.

A number of π-extended porphyrins and bis-porphyrins were characterised by resonance Raman spectroscopy and density functional theory (DFT) calculations, using both B3LYP and CAM-B3LYP functionals. Single porphyrin species, incorporating a β,β'-fused quinoxalino unit, and tetraazaanthracene-bridged bis-porphyrins were investigated. Geometry optimisation predicted all species were planar with respect to the porphyrin core(s). Comparison of experimental with simulated vibrational spectra, obtained via DFT calculations [B3LYP/6-31G(d)], verified the modelling; demonstrated by a mean absolute deviation (MAD) between experimental and calculated band positions of less than 10 cm-1. Simulated electronic transitions obtained via time-dependent DFT [TD-DFT, B3LYP and CAM-B3LYP/6-31G(d)] lay within 0.4 eV of experimental bands and calculations showed perturbation of the frontier molecular orbitals (FMOs) following substitution of the porphyrin core. The nature of transitions that were investigated experimentally via resonance Raman enhancement showed consistency with the character of calculated transitions. A wavepacket analysis of the resonance Raman intensities provided electronic parameters, such as reorganisation energy, as well as normal mode displacements (Δi) that were also consistent with the nature of the specific vibrational modes and probed optical transitions. The largest vibrational reorganisation value obtained was for the Bsh band of compound (1). This result is consistent with the greater electron density shift of the transition found from DFT and resonance Raman and also the less symmetrical nature of (1).

Building resilience to food insecurity in rural communities: Evidence from traditional institutions in Zimbabwe

PubMed Central

2017-01-01

Many rural communities that depend on smallholder farming face food insecurity induced by climate-related disasters. In response, some communities are taking the initiative to cope and adapt to climate-related disasters. Using case study material from the Zambezi Valley, Zimbabwe, this article examines how traditional institutions are enhancing resilience to food insecurity in rural areas. The data were collected through interviews and focus groups involving traditional leaders, ward councillors, village civil protection members and villagers selected in the valley. The findings point to how the Zunde raMambo informal safety net, nhimbe form of collective work and the practice of share-rearing arrangement to access draught power help save lives and alleviate food insecurity induced by flood or drought disasters. The study concludes that the three schemes are evidence of community reorganisation or change in response to food insecurity. They are a form of absorptive capacities enabling the community to cope with food insecurity.

Objectives To determine if NHS reforms affect population mortality. Design Retrospective study using routinely published data. Setting & participants Resident population of England and Wales 1948 to 2012 Main outcome measure All cause age sex directly standardised mortality England and Wales 1948 to 2012. Methods Using the CuSum technique and Change-Point Analysis to identify sustained changes in the improving age-standardised mortality rates for the period 1948-2012, and comparing the time of these changes with periods of NHS reform. Where observed changes did not fit with NHS reform, changes external to the NHS were sought as a possible explanation of changes observed. Results CuSum plotting and CPA showed no significant changes in female mortality trend between 1948 and 2012. However, this analysis identified a sustained improvement in the male mortality trend, occurring in the mid-1970s. A further change in the rate of male mortality decline was found around the Millennium. Conclusion The 1974 NHS reorganisation, changing service arrangements predominantly for women and children, is considered an unlikely explanation of the improved rate of male mortality decline. Thus, centrally led NHS reorganisation has never had any detectable effect on either male or female mortality and must be considered ineffective for this purpose. But some evidence supporting the view that increased funding improves outcomes is found. PMID:26432817

To present the results of a strengths, weaknesses, opportunities and threats (SWOT) analysis used as part of a process aimed at reorganising services provided within a pediatric rehabilitation programme (PRP) in Quebec, Canada and to report the perceptions of the planning committee members regarding the usefulness of the SWOT in this process. Thirty-six service providers working in the PRP completed a SWOT questionnaire and reported what they felt worked and what did not work in the existing model of care. Their responses were used by a planning committee over a 12-month period to assist in the development of a new service delivery model. Committee members shared their thoughts about the usefulness of the SWOT. Current programme strengths included favourable organisational climate and interdisciplinary work whereas weaknesses included lack of psychosocial support to families and long waiting times for children. Opportunities included working with community partners, whereas fear of losing professional autonomy with the new service model was a threat. The SWOT results helped the planning committee redefine the programme goals and make decisions to improve service coordination. SWOT analysis was deemed as a very useful tool to help guide service reorganisation. SWOT analysis appears to be an interesting evaluation tool to promote awareness among service providers regarding the current functioning of a rehabilitation programme. It fosters their active participation in the reorganisation of a new service delivery model for pediatric rehabilitation.

Current psychiatric-psychotherapeutic in-patient care takes place in an area of tension between increasing treatment requirements and the persistent lack of qualified staff. The optimisation of the diagnostic-therapeutic procedures in a clinic helps to reduce existing care deficits or to generate resources for future developments. The subject of delegation and substitution of medical services is considered in this context. Inadequate knowledge of the legal situation on the part of the decision makers impairs the indispensable trustful cooperation among the professions and adds to the uncertainty of all those concerned. The present paper outlines the legal, organisational and health policy aspects of delegation and the reorganisation of medical activities in the field of psychiatry. © Georg Thieme Verlag KG Stuttgart · New York.

Chromatin reorganisation in Epstein-Barr virus-infected cells and its role in cancer development.

PubMed

West, Michelle J

2017-10-01

The oncogenic Epstein-Barr virus (EBV) growth transforms B cells and drives lymphoma and carcinoma development. The virus encodes four key transcription factors (EBNA2, EBNA3A, EBNA3B and EBNA3C) that hijack host cell factors to bind gene control elements and reprogramme infected B cells. These viral factors predominantly target long-range enhancers to alter the expression of host cell genes that control B cell growth and survival and facilitate virus persistence. Enhancer and super-enhancer binding by these EBNAs results in large-scale reorganisation of three-dimensional enhancer-promoter architecture to drive the overexpression of oncogenes, the silencing of tumour suppressors and the modulation of transcription, cell-cycle progression, migration and adhesion.

To identify facial expressions occurring in patients at risk of deterioration in hospital wards. Prospective observational feasibility study. General ward patients in a London Community Hospital, United Kingdom. Thirty-four patients at risk of clinical deterioration. A 5-minute video (25 frames/s; 7,500 images) was recorded, encrypted, and subsequently analyzed for action units by a trained facial action coding system psychologist blinded to outcome. Action units of the upper face, head position, eyes position, lips and jaw position, and lower face were analyzed in conjunction with clinical measures collected within the National Early Warning Score. The most frequently detected action units were action unit 43 (73%) for upper face, action unit 51 (11.7%) for head position, action unit 62 (5.8%) for eyes position, action unit 25 (44.1%) for lips and jaw, and action unit 15 (67.6%) for lower face. The presence of certain combined face displays was increased in patients requiring admission to intensive care, namely, action units 43 + 15 + 25 (face display 1, p < 0.013), action units 43 + 15 + 51/52 (face display 2, p < 0.003), and action units 43 + 15 + 51 + 25 (face display 3, p < 0.002). Having face display 1, face display 2, and face display 3 increased the risk of being admitted to intensive care eight-fold, 18-fold, and as a sure event, respectively. A logistic regression model with face display 1, face display 2, face display 3, and National Early Warning Score as independent covariates described admission to intensive care with an average concordance statistic (C-index) of 0.71 (p = 0.009). Patterned facial expressions can be identified in deteriorating general ward patients. This tool may potentially augment risk prediction of current scoring systems.

National Health Service England recently oversaw a whole-scale reconfiguration of cancer services in London, UK, for a number of different cancer pathways. Centralisation of cancer surgery has occurred with prostate cancer (PCa) surgery only being commissioned at a single designated pelvic cancer surgical centre. This process has required surgeons to work in teams providing a hub-and-spoke model of care. To report the extent to which the initiation of a quality assurance programme (QAP) can improve the quality of PCa surgical care during reorganisation of cancer services in London. A pre- and postintervention study was initiated with 732 men undergoing robot-assisted radical PCa surgery over a 3-yr period, 396 men before the introduction of the QAP and 336 afterwards. Image-based surgical planning of cancer surgery and monthly peer review of individual surgeon outcomes incorporating rating and assessment of edited surgical video clips. We observed margin status (positive/negative), complication rate of surgery, 3-mo urinary continence, use of nerve-sparing surgery, and potency at 12 mo after surgery. Multivariable logistic regression modelling was used to compare outcomes before and after initiation of the QAP. Cox regression analysis was used to evaluate the return of potency over time. Demographics of patients undergoing surgery did not change following the reorganisation of cancer services. Patient-reported 3-mo urinary continence improved following the initiation of the QAP, both in terms of requirement for incontinence pads (57% continent vs 67% continent; odds ratio [OR]: 2.19; 95% confidence interval [CI], 1.08-4.46; p=0.02) and International Consultation on Incontinence Questionnaire score (5.6 vs 4.2; OR: 0.82; 95% CI, 0.70-0.95; p=0.009). Concurrently, use of nerve-sparing surgery increased significantly (OR: 2.99; 95% CI, 2.14-4.20; p<0.001) while margin status remained static. Potency at 12 mo increased significantly from 21% to 61% in those patients undergoing bilateral nerve-sparing surgery (hazard ratio: 3.58; 95% CI, 1.29-9.87; p=0.04). Interaction was noted between surgeon and 3-mo urinary continence. On regression analysis, incontinence scores improved significantly for all but one surgeon who had low incontinence rates at study initiation. The implementation of a QAP improved quality of care in terms of consistency of patient selection and outcomes of surgery during a period of major reorganisation of cancer services in London. The QAP framework presented could be adopted by other organisations providing complex surgical care across a large network of referring hospitals. The introduction of a quality assurance programme improved the quality of prostate cancer care in terms of consistency of patient selection and outcomes of surgery during a period of major reorganisation of cancer services.

In 1991 it was decided to reorganise the transfusion service of the County of Funen. The aims were to standardise and improve the quality of blood components, laboratory procedures and the transfusion service and to reduce the number of outdated blood units. Part of the efficiency gains was reinvested in a dedicated computer system making it possible--among other things--to change the cross-match procedures from serological to computer cross-matching according to the ABCD-concept. This communication describes how this transition was performed in terms of laboratory techniques, education of personnel as well as implementation of the computer system and indicates the results obtained. The Funen Transfusion Service has by now performed more than 100.000 red cell transfusions based on ABCD-cross-matching and has not encountered any problems. Major results are the significant reductions of cross-match procedures, blood grouping as well as the number of outdated blood components.

Stroke mimic diagnoses presenting to a hyperacute stroke unit.

Stroke services have been centralised in several countries in recent years. Diagnosing acute stroke is challenging and a high proportion of patients admitted to stroke units are diagnosed as a non-stroke condition (stroke mimics). This study aims to describe the stroke mimic patient group, including their impact on stroke services. We analysed routine clinical data from 2,305 consecutive admissions to a stroke unit at St George's Hospital, London. Mimic groupings were derived from 335 individual codes into 17 groupings. From 2,305 admissions, 555 stroke mimic diagnoses were identified (24.2%) and 72% of stroke mimics had at least one stroke risk factor. Common mimic diagnoses were headache, seizure and syncope. Medically unexplained symptoms and decompensation of underlying conditions were also common. Median length of stay was 1 day; a diagnosis of dementia (p=0.028) or needing MRI (p=0.006) was associated with a longer stay. Despite emergency department assessment by specialist clinicians and computed tomography brain, one in four suspected stroke patients admitted to hospital had a non-stroke diagnosis. Stroke mimics represent a heterogeneous patient group with significant impacts on stroke services. Co-location of stroke and acute neurology services may offer advantages where service reorganisation is being considered. © Royal College of Physicians 2016. All rights reserved.

Improving Posthospital Discharge Telephone Reach Rates Through Prehospital Discharge Face-to-Face Meetings.

Vergara, Franz H; Sheridan, Daniel J; Sullivan, Nancy J; Budhathoki, Chakra

The purpose of this study was to determine whether a face-to-face meeting with patients by a telephonic case manager prehospital discharge would result in increased telephone follow-up (TFU) reach rates posthospital discharge. Acute care adult medicine inpatient units. A quasiexperimental design was utilized. Two adult inpatient medicine units were selected as the intervention and comparison groups. The framework of the study is the transitions theory. A convenience sampling technique was used, whereby 88 eligible patients on the intervention unit received face-to-face meetings prehospital discharge whereas 123 patients on the comparison unit received standard care (no face-to-face meetings). Cross-tabulation and chi-square tests were employed to examine the association of face-to-face meeting intervention and TFU reach rates. Implementing brief (<10 min) face-to-face meetings by a telephonic case manager prehospital discharge resulted in a TFU reach rate of 87% on the intervention unit, whereas the comparison unit only had a 58% TFU reach rate (p < .001). Increasing reach rates by a telephonic case manager facilitates communication with more patients posthospital discharge. A brief prehospital discharge face-to-face meeting with patients assisted them to understand the reasons for a posthospital discharge telephone call, identified the best times to call using accurate telephone numbers, and taught patients how best to prepare for the call. In addition, by meeting patients face-to-face, the telephonic case manager was no longer an unknown person on the telephone asking them questions about their medical condition. These factors combined may have significantly helped to increase TFU reach rates.

Here, we exploit the spatial separation of temporal events of neural differentiation in the elongating chick body axis to provide the first analysis of transcriptome change in progressively more differentiated neural cell populations in vivo. Microarray data, validated against direct RNA sequencing, identified: (1) a gene cohort characteristic of the multi-potent stem zone epiblast, which contains neuro-mesodermal progenitors that progressively generate the spinal cord; (2) a major transcriptome re-organisation as cells then adopt a neural fate; and (3) increasing diversity as neural patterning and neuron production begin. Focussing on the transition from multi-potent to neural state cells, we capture changes in major signalling pathways, uncover novel Wnt and Notch signalling dynamics, and implicate new pathways (mevalonate pathway/steroid biogenesis and TGFβ). This analysis further predicts changes in cellular processes, cell cycle, RNA-processing and protein turnover as cells acquire neural fate. We show that these changes are conserved across species and provide biological evidence for reduced proteasome efficiency and a novel lengthening of S phase. This latter step may provide time for epigenetic events to mediate large-scale transcriptome re-organisation; consistent with this, we uncover simultaneous downregulation of major chromatin modifiers as the neural programme is established. We further demonstrate that transcription of one such gene, HDAC1, is dependent on FGF signalling, making a novel link between signals that control neural differentiation and transcription of a core regulator of chromatin organisation. Our work implicates new signalling pathways and dynamics, cellular processes and epigenetic modifiers in neural differentiation in vivo, identifying multiple new potential cellular and molecular mechanisms that direct differentiation. © 2014.

Within land vertebrate species, snakes display extreme variations in their body plan, characterized by the absence of limbs and an elongated morphology. Such a particular interpretation of the basic vertebrate body architecture has often been associated with changes in the function or regulation of Hox genes. Here, we use an interspecies comparative approach to investigate different regulatory aspects at the snake HoxD locus. We report that, unlike in other vertebrates, snake mesoderm-specific enhancers are mostly located within the HoxD cluster itself rather than outside. In addition, despite both the absence of limbs and an altered Hoxd gene regulation in external genitalia, the limb-associated bimodal HoxD chromatin structure is maintained at the snake locus. Finally, we show that snake and mouse orthologous enhancer sequences can display distinct expression specificities. These results show that vertebrate morphological evolution likely involved extensive reorganisation at Hox loci, yet within a generally conserved regulatory framework.

Regimental Medical Officer Charles McKerrow: saving lives on the Western Front.

Mayhew, E

2014-01-01

Ayrshire general practitioner Charles McKerrow was appointed regimental medical officer (RMO) to the 10th Battalion Northumberland Fusiliers in 1915. At this time, fundamental restructuring of the military medical service on the Western Front had two main effects: surgical capability was moved forward as close to the front as possible and specialist stretcher bearers were trained to apply emergency first aid at the place of injury and to triage casualties appropriately. The specialist stretcher bearers were the equivalent of today's combat medical technicians. The reorganisation was undertaken in a rapid, improvised 'bottom-up' manner and there are very few official records to detail the process. McKerrow and RMOs of his calibre were integral to the successful implementation and operation of this reorganisation so their personal archives are the primary sources for its history. McKerrow's record is particularly detailed and insightful on the process; he was not only an extraordinarily fine medical officer but also provided expert testimony on a period of military medical change that was enduringly successful.

The roles of plate tectonic or mantle dynamic forces in rupturing continental lithosphere remain controversial. Particularly enigmatic is the rifting of microcontinents from mature continental rifted margins, with plume-driven thermal weakening commonly inferred to facilitate calving. However, a role for plate tectonic reorganisations has also been suggested. Here, we show that a combination of plate tectonic reorganisation and plume-driven thermal weakening were required to calve the Batavia and Gulden Draak microcontinents in the Cretaceous Indian Ocean. We reconstruct the evolution of these two microcontinents using constraints from new paleontological samples, 40Ar/39Ar ages, and geophysical data. Calving from India occurred at 101-104 Ma, coinciding with the onset of a dramatic change in Indian plate motion. Critically, Kerguelen plume volcanism does not appear to have directly triggered calving. Rather, it is likely that plume-related thermal weakening of the Indian passive margin preconditioned it for microcontinent formation but calving was triggered by changes in plate tectonic boundary forces.

Rodriguez-Lorenzo, Andres; Audolfsson, Thorir; Wong, Corrine; Cheng, Angela; Arbique, Gary; Nowinski, Daniel; Rozen, Shai

2015-10-01

The aim of this study was to evaluate the contribution of a single unilateral facial vein in the venous outflow of total-face allograft using three-dimensional computed tomographic imaging techniques to further elucidate the mechanisms of venous complications following total-face transplant. Full-face soft-tissue flaps were harvested from fresh adult human cadavers. A single facial vein was identified and injected distally to the submandibular gland with a radiopaque contrast (barium sulfate/gelatin mixture) in every specimen. Following vascular injections, three-dimensional computed tomographic venographies of the faces were performed. Images were viewed using TeraRecon Software (Teracon, Inc., San Mateo, CA, USA) allowing analysis of the venous anatomy and perfusion in different facial subunits by observing radiopaque filling venous patterns. Three-dimensional computed tomographic venographies demonstrated a venous network with different degrees of perfusion in subunits of the face in relation to the facial vein injection side: 100% of ipsilateral and contralateral forehead units, 100% of ipsilateral and 75% of contralateral periorbital units, 100% of ipsilateral and 25% of contralateral cheek units, 100% of ipsilateral and 75% of contralateral nose units, 100% of ipsilateral and 75% of contralateral upper lip units, 100% of ipsilateral and 25% of contralateral lower lip units, and 50% of ipsilateral and 25% of contralateral chin units. Venographies of the full-face grafts revealed better perfusion in the ipsilateral hemifaces from the facial vein in comparison with the contralateral hemifaces. Reduced perfusion was observed mostly in the contralateral cheek unit and contralateral lower face including the lower lip and chin units.

Long-range cis-regulatory elements such as enhancers coordinate cell-specific transcriptional programmes by engaging in DNA looping interactions with target promoters. Deciphering the interplay between the promoter connectivity and activity of cis-regulatory elements during lineage commitment is crucial for understanding developmental transcriptional control. Here, we use Promoter Capture Hi-C to generate a high-resolution atlas of chromosomal interactions involving ~22,000 gene promoters in human pluripotent and lineage-committed cells, identifying putative target genes for known and predicted enhancer elements. We reveal extensive dynamics of cis-regulatory contacts upon lineage commitment, including the acquisition and loss of promoter interactions. This spatial rewiring occurs preferentially with predicted changes in the activity of cis-regulatory elements and is associated with changes in target gene expression. Our results provide a global and integrated view of promoter interactome dynamics during lineage commitment of human pluripotent cells. DOI: http://dx.doi.org/10.7554/eLife.21926.001 PMID:28332981

Rehabilitation of the central executive component of working memory: a re-organisation approach applied to a single case.

PubMed

Duval, J; Coyette, F; Seron, X

2008-08-01

This paper describes and evaluates a programme of neuropsychological rehabilitation which aims to improve three sub-components of the working memory central executive: processing load, updating and dual-task monitoring, by the acquisition of three re-organisation strategies (double coding, serial processing and speed reduction). Our programme has two stages: cognitive rehabilitation (graduated exercises subdivided into three sub-programmes each corresponding to a sub-component) which enables the patient to acquire the three specific strategies; and an ecological rehabilitation, including analyses of scenarios and simulations of real-life situations, which aims to transfer the strategies learned to everyday life. The programme also includes information meetings. It was applied to a single case who had working memory deficits after a surgical operation for a cerebral tumour on his left internal temporal ganglioglioma. Multiple baseline tests were used to measure the effectiveness of the rehabilitation. The programme proved to be effective for all three working memory components; a generalisation of its effects to everyday life was observed, and the effects were undiminished three months later.

DFT/TDDFT investigation on the photophysical properties of a series of phosphorescent cyclometalated complexes based on the benchmark complex FIrpic

NASA Astrophysics Data System (ADS)

Han, Deming; Gong, Ping; Lv, Shuhui; Zhao, Lihui; Zhao, Henan

2018-05-01

The photophysical properties of four Ir(III) complexes have been investigated by means of the density functional theory/time-dependent density functional theory (DFT/TDDFT). The effect of the electron-withdrawing and electron-donating substituents on charge injection, transport, absorption and phosphorescent properties has been studied. The theoretical calculation shows that the lowest-lying singlet absorptions for complexes 1-4 are located at 387, 385, 418 and 386 nm, respectively. For 1-4, the phosphorescence at 465, 485, 494 and 478 nm is mainly attributed to the LUMO → HOMO and LUMO → HOMO-1 transition configurations characteristics. In addition, ionisation potential (IP), electron affinities (EAs) and reorganisation energy have been investigated to evaluate the charge transfer and balance properties between hole and electron. The balance of the reorganisation energies for complex 3 is better than others. The difference between hole transport and electron transport for complex 3 is the smallest among these complexes, which is beneficial to achieve the hole and electron transfer balance in emitting layer.

Faunal reorganisation in terrestrial mammalian communities: evidence from France during the Lateglacial-Early Holocene transition

NASA Astrophysics Data System (ADS)

Bridault, Anne

2010-05-01

The Lateglacial-Early Holocene transition is characterized by rapid oscillations between warm and cold episodes. Their impact on ecosystem dynamics was particularly pronounced in north-western Europe where hunter-gatherer societies experienced a succession of environmental transformations, including the expansion and dispersal of biotic communities and changing herbivore habitats. Recent archaeozoological studies and AMS direct dating on mammalian bones/or bone collagen allow to map and precise this process at a supra-regional scale (France). At regional scales (i.e. Paris Basin & Jura-Northern French Alps), results indicate a rapid faunal reorganisation at the end of Lateglacial that will be presented in detail. Composition of faunal assemblages remains then unchanged during the Early Holocene. By contrast, significant herbivore habitat changes are recorded during the Early Holocene by other proxies (pollen data and isotopic data) and a decrease in Red Deer size through time is evidenced by osteometrical analyses. Hypotheses regarding the kind of adaptation process experienced by the faunal communities through time will be presented. Factors that may have controlled the observed changes will be discussed.

Verhoog, Roelof

2001-10-02

A one-piece battery comprises a tank divided into cells each receiving an electrode assembly, closure means for the tank and a circulating fluid type heat exchanger facing the relatively larger faces of the electrode assembly. The fluid flows in a compartment defined by two flanges which incorporate a fluid inlet orifice communicating with a common inlet manifold and a fluid outlet orifice communicating with a common outlet manifold. The tank comprises at least two units and each unit comprises at least one cell delimited by walls. The wall facing a relatively larger face of the electrode assembly constitutes one of the flanges. Each unit further incorporates a portion of an inlet and outlet manifold. The units are fastened together so that the flanges when placed face-to-face form a sealed circulation compartment and the portions of the same manifold are aligned with each other.

[Innovation in healthcare processes and patient safety using clinical simulation].

PubMed

Rojo, E; Maestre, J M; Díaz-Mendi, A R; Ansorena, L; Del Moral, I

2016-01-01

Many excellent ideas are never implemented or generalised by healthcare organisations. There are two related paradigms: thinking that individuals primarily change through accumulating knowledge, and believing that the dissemination of that knowledge within the organisation is the key element to facilitate change. As an alternative, a description and evaluation of a simulation-based inter-professional team training program conducted in a Regional Health Service to promote and facilitate change is presented. The Department of Continuing Education completed the needs assessment using the proposals presented by clinical units and management. Skills and behaviors that could be learned using simulation were selected, and all personnel from the units participating were included. Experiential learning principles based on clinical simulation and debriefing, were used for the instructional design. The Kirkpatrick model was used to evaluate the program. Objectives included: a) decision-making and teamwork skills training in high prevalence diseases with a high rate of preventable complications; b) care processes reorganisation to improve efficiency, while maintaining patient safety; and, c) implementation of new complex techniques with a long learning curve, and high preventable complications rate. Thirty clinical units organised 39 training programs in the 3 public hospitals, and primary care of the Regional Health Service during 2013-2014. Over 1,559 healthcare professionals participated, including nursing assistants, nurses and physicians. Simulation in healthcare to train inter-professional teams can promote and facilitate change in patient care, and organisational re-engineering. Copyright © 2016 SECA.

Determining the Molecular Growth Mechanisms of Protein Crystal Faces by Atomic Force Microscopy

NASA Technical Reports Server (NTRS)

Nadarajah, Arunan; Li, Huayu; Pusey, Marc L.

1999-01-01

A high resolution atomic force microscopy (AFM) study had shown that the molecular packing on the tetragonal lysozyme (110) face corresponded to only one of two possible packing arrangements, suggesting that growth layers on this face were of bimolecular height. Theoretical analyses of the packing also indicated that growth of this face should proceed by the addition of growth units of at least tetramer size corresponding to the 43 helices in the crystal. In this study an AFM linescan technique was devised to measure the dimensions of individual growth units on protein crystal faces as they were being incorporated into the lattice. Images of individual growth events on the (110) face of tetragonal lysozyme crystals were observed, shown by jump discontinuities in the growth step in the linescan images as shown in the figure. The growth unit dimension in the scanned direction was obtained from these images. A large number of scans in two directions on the (110) face were performed and the distribution of lysozyme growth unit sizes were obtained. A variety of unit sizes corresponding to 43 helices, were shown to participate in the growth process, with the 43 tetramer being the minimum observed size. This technique represents a new application for AFM allowing time resolved studies of molecular process to be carried out.

Tanasescu, Radu; Cottam, William J; Condon, Laura; Tench, Christopher R; Auer, Dorothee P

2016-09-01

Maladaptive mechanisms of pain processing in chronic pain conditions (CP) are poorly understood. We used coordinate based meta-analysis of 266 fMRI pain studies to study functional brain reorganisation in CP and experimental models of hyperalgesia. The pattern of nociceptive brain activation was similar in CP, hyperalgesia and normalgesia in controls. However, elevated likelihood of activation was detected in the left putamen, left frontal gyrus and right insula in CP comparing stimuli of the most painful vs. other site. Meta-analysis of contrast maps showed no difference between CP, controls, mood conditions. In contrast, experimental hyperalgesia induced stronger activation in the bilateral insula, left cingulate and right frontal gyrus. Activation likelihood maps support a shared neural pain signature of cutaneous nociception in CP and controls. We also present a double dissociation between neural correlates of transient and persistent pain sensitisation with general increased activation intensity but unchanged pattern in experimental hyperalgesia and, by contrast, focally increased activation likelihood, but unchanged intensity, in CP when stimulated at the most painful body part.

Quantifying the Adaptive Cycle | Science Inventory | US EPA

EPA Pesticide Factsheets

The adaptive cycle was proposed as a conceptual model to portray patterns of change in complex systems. Despite the model having potential for elucidating change across systems, it has been used mainly as a metaphor, describing system dynamics qualitatively. We use a quantitative approach for testing premises (reorganisation, conservatism, adaptation) in the adaptive cycle, using Baltic Sea phytoplankton communities as an example of such complex system dynamics. Phytoplankton organizes in recurring spring and summer blooms, a well-established paradigm in planktology and succession theory, with characteristic temporal trajectories during blooms that may be consistent with adaptive cycle phases. We used long-term (1994–2011) data and multivariate analysis of community structure to assess key components of the adaptive cycle. Specifically, we tested predictions about: reorganisation: spring and summer blooms comprise distinct community states; conservatism: community trajectories during individual adaptive cycles are conservative; and adaptation: phytoplankton species during blooms change in the long term. All predictions were supported by our analyses. Results suggest that traditional ecological paradigms such as phytoplankton successional models have potential for moving the adaptive cycle from a metaphor to a framework that can improve our understanding how complex systems organize and reorganize following collapse.

Task uncertainty and communication during nursing shift handovers.

PubMed

Mayor, Eric; Bangerter, Adrian; Aribot, Myriam

2012-09-01

We explore variations in handover duration and communication in nursing units. We hypothesize that duration per patient is higher in units facing high task uncertainty. We expect both topics and functions of communication to vary depending on task uncertainty. Handovers are changing in modern healthcare organizations, where standardized procedures are increasingly advocated for efficiency and reliability reasons. However, redesign of handover should take environmental contingencies of different clinical unit types into account. An important contingency in institutions is task uncertainty, which may affect how communicative routines like handover are accomplished. Nurse unit managers of 80 care units in 18 hospitals were interviewed in 2008 about topics and functions of handover communication and duration in their unit. Interviews were content-analysed. Clinical units were classified into a theory-based typology (unit type) that gradually increases on task uncertainty. Quantitative analyses were performed. Unit type affected resource allocation. Unit types facing higher uncertainty had higher handover duration per patient. As expected, unit type also affected communication content. Clinical units facing higher uncertainty discussed fewer topics, discussing treatment and care and organization of work less frequently. Finally, unit type affected functions of handover: sharing emotions was less often mentioned in unit types facing higher uncertainty. Task uncertainty and its relationship with functions and topics of handover should be taken into account during the design of handover procedures. © 2011 Blackwell Publishing Ltd.

Grades, Student Satisfaction and Retention in Online and Face-to-Face Introductory Psychology Units: A Test of Equivalency Theory.

PubMed

Garratt-Reed, David; Roberts, Lynne D; Heritage, Brody

2016-01-01

There has been a recent rapid growth in the number of psychology courses offered online through institutions of higher education. The American Psychological Association has highlighted the importance of ensuring the effectiveness of online psychology courses (Halonen et al., 2013). Despite this, there have been inconsistent findings regarding student grades, satisfaction, and retention in online psychology units. Equivalency Theory (Simonson, 1999; Simonson et al., 1999) posits that online and classroom-based learners will attain equivalent learning outcomes when equivalent learning experiences are provided. We present a study of an online introductory psychology unit designed to provide equivalent learning experiences to the pre-existing face-to-face version of the unit. Using quasi-experimental methods, academic performance, student feedback, and retention data from 866 Australian undergraduate psychology students were examined to assess whether the online unit developed to provide equivalent learning experiences produced comparable outcomes to the 'traditional' unit delivered face-to-face. Student grades did not significantly differ between modes of delivery, except for a group-work based assessment where online students performed more poorly. Student satisfaction was generally high in both modes of the unit, with group-work the key source of dissatisfaction in the online unit. The results provide partial support for Equivalency Theory. The group-work based assessment did not provide an equivalent learning experience for students in the online unit highlighting the need for further research to determine effective methods of engaging students in online group activities. Consistent with previous research, retention rates were significantly lower in the online unit, indicating the need to develop effective strategies to increase online retention rates. While this study demonstrates successes in presenting students with an equivalent learning experience, we recommend that future research investigate means of successfully facilitating collaborative group-work assessment, and to explore contributing factors to actual student retention in online units beyond that of non-equivalent learning experiences.

Large Colloids in Cholesteric Liquid Crystals

Stratford, K.; Gray, A.; Lintuvuori, J. S.

2015-12-01

We describe a coarse-grained Landau-de Gennes model of liquid crystals (LCs) including hydrodynamics based on the Beris-Edwards equations. The model is employed to study the impact of large colloids on the long range LC defect structure in the cholesteric LC blue phases. `Large' here means that the particle size is comparable to the cholesteric pitch, the length scale on which the LC order undergoes a helical twist. We investigate the case of a single particle, with either normal or degenerate planar anchoring, placed initially in an equilibrium blue phase LC. It is found that in some cases, well defined steady disclination structure emerges at the particle surface, while in other cases no clear steady state is reached in the simulations, and disclination reorganisation appears to proliferate through the bulk LC. These systems are of potential interest in the context of using LCs to template self-assembly of colloid structure, e.g., for opto-electronic devices. Computationally, we demonstrate a parallel approach using mixed message-passing and threaded model on graphical processing units allows effective and efficient progress for this problem.

2016-11-17

An integrated chronic disease management (ICDM) model consisting of four components (facility reorganisation, clinical supportive management, assisted self-supportive management and strengthening of support systems and structures outside the facility) has been implemented across 42 primary health care clinics in South Africa with a view to improve the operational efficiency and patient clinical outcomes. The aim of this study was to assess the sustainability of the facility reorganisation and clinical support components 18 months after the initiation. The study was conducted at 37 of the initiating clinics across three districts in three provinces of South Africa. The National Health Service (NHS) Institute for Innovation and Improvement Sustainability Model (SM) self-assessment tool was used to assess sustainability. Bushbuckridge had the highest mean sustainability score of 71.79 (95% CI: 63.70-79.89) followed by West Rand Health District (70.25 (95% CI: 63.96-76.53)) and Dr Kenneth Kaunda District (66.50 (95% CI: 55.17-77.83)). Four facilities (11%) had an overall sustainability score of less than 55. The less than optimal involvement of clinical leadership (doctors), negative staff behaviour towards the ICDM, adaptability or flexibility of the model to adapt to external factors and infrastructure limitation have the potential to negatively affect the sustainability and scale-up of the model.

Early diagnosis of rheumatic diseases: an evaluation of the present situation and proposed changes

Musculoskeletal pain is a very common complaint, affecting 30–40% of the European population. It is estimated that approximately 400,000 Poles suffer from inflammatory rheumatic diseases, such as rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis, and a vast majority of those affected are working-age individuals. Patients with suspected arthritis require prompt diagnosis and treatment, as any delays may result in irreversible joint destruction and disability. Currently in Poland, the lag time between the onset of symptoms and diagnosis is, on average, as much as 35 weeks. In this paper, we review the current state of specialist rheumatology care in Poland and propose a reorganised care model that includes early diagnosis of inflammatory arthritis. The main goal we wish to achieve with our reorganised model is to enhance access to outpatient specialist rheumatology care for patients with suspected arthritis. We believe that our model should make it possible to considerably reduce the lag time between GP referral and the diagnosis and treatment by a rheumatologist to as little as 3 to 4 weeks. This article provides a proposal of changes that would achieve this goal and is a summary of the report published by the Institute of Rheumatology in September 2014. PMID:27407218

Through the glass ceiling - and back again: the experiences of two of the first non-medical directors of public health in England.

PubMed

Evans, David; Adams, Lee

2007-06-01

In 2001, the English Department of Health announced a radical re-organisation of the NHS under the banner of 'shifting the balance of power'. As part of this re-organisation health authorities were abolished and the main NHS public health responsibilities devolved to the new primary care trusts (PCTs) from April 2002. Following several years of campaigning by the Multidisciplinary Public Health Forum (MPHF), in November 2001 the Acting Minister for Public Health, Lord Hunt, announced that PCT director of public health (DPH) posts would be open to 'suitably qualified' candidates from any discipline. From April 2002 a number of new DsPH from backgrounds other than medicine were appointed. This paper reports on the experiences of two such DsPH who shared a commitment to multidisciplinary public health, but who did not wholly share the objectives of the MPHF. We place the opening of PCT DPH posts in the context of tensions within NHS public health between a focus on health services versus the wider determinants of health, and the development of multidisciplinary public health. The paper reflects on both the degree of change this opening represented and the limitations and tensions such appointments exposed.

An extended field test of the WHO severe malnutrition guidelines in hospitals in developing countries: preliminary observations.

2003-01-01

The WHO has published guidelines for the inpatient management of severe malnutrition. A qualitative study in hospitals in developing countries is being conducted to document the re-organisation of the clinical ward and support services required to implement these guidelines and to gain an impression of the feasibility and sustainability of such a re-organisation. Following a postal survey of experts in the management of malnutrition in children in developing countries, hospitals were contacted and asked if they were interested to participate in the study. If so, they were requested to submit background information about admission patterns, the frequency of malnutrition, and current practice. Based on this information, hospitals are selected for a preliminary visit. Following this, and the final selection, a paediatrician conducts three visits to the study hospital over a one-year period to appraise the current practice, assist the health staff in recognising the strengths and shortcomings of their current management, help them find locally appropriate solutions, support the implementation process through a participatory approach and assess the outcome. A structured survey instrument is used to guide the assessment and identification of problems. Results of the first visit, which documents the existing situation, and changes identified by staff and implemented during the second visit are presented.

Arrangement for controlled engagement of the tools of a mining machine with a mine face

An arrangement for controlled engagement of the tools of a coal planer, with a mine face comprises a scraper conveyor, provided on its front face directed toward the mine face with a guide rail guiding the coal planer for reciprocation along the mine face and a mechanism for tilting the conveyor and the coal planer about a substantially horizontal axis. The tilting mechanism is connected to the rear face of the conveyor and extends in its entirety rearwardly of the rear face of the latter. The tilting mechanism comprises a guide linkage pivotally connected at its front end to themore » rear face of the scraper conveyor while its rear end portion forms a housing for a fluid operated cylinder and piston unit, the piston rod of which is connected to a connecting rod guided by the guide linkage for movement in longitudinal direction and having an upwardly extending front section pivotally connected at its upper free end to the rear face of the scraper conveyor. The fluid operated cylinder-and-piston unit is thus considerably spaced from the scraper conveyor and the material transported thereby and especially coal dust raised during transport of the mined coal by the conveyor, whereby maintenance of the tilting unit is reduced. The guide linkage, the connecting rod and the tilting unit are all in close vicinity to the sole of the mine gallery to leave a considerable free space between the arrangement and the roof of the mine gallery.« less

Determining the Molecular Growth Mechanisms of Protein Crystal faces by Atomic Force Microscopy

NASA Technical Reports Server (NTRS)

Li, Huayu; Nadarajah, Arunan; Pusey, Marc L.

1998-01-01

A high resolution atomic force microscopy (AFM) study had shown that the molecular packing on the tetragonal lysozyme (110) face corresponded to only one of two possible packing arrangements, suggesting that growth layers on this face were of bimolecular height (Li et al., 1998). Theoretical analyses of the packing had also indicated that growth of this face should proceed by the addition of growth units of at least tetramer size corresponding to the 43 helices in the crystal. In this study an AFM linescan technique was devised to measure the dimensions of individual growth units on protein crystal faces. The growth process of tetragonal lysozyme crystals was slowed down by employing very low supersaturations. As a result images of individual growth events on the (110) face were observed, shown by jump discontinuities in the growth step in the linescan images. The growth unit dimension in the scanned direction was obtained by suitably averaging these images. A large number of scans in two directions on the (110) face were performed and the distribution of lysozyme aggregate sizes were obtained. A variety of growth units, all of which were 43 helical lysozyme aggregates, were shown to participate in the growth process with a 43 tetramer being the minimum observed size. This technique represents a new application for AFM allowing time resolved studies of molecular process to be carried out.

The first part of this contribution attempts to recapitulate the economic and social conditions facing educational policy in post-colonial Africa. The second part shows that the dependence on world economy is aggravated by the separation of education from productive work, which is a concomitant of the institutionalisation of education. In the communally-organised traditional African societies, education was incumbent on all members of the society; it was part of the common life-and-work process. It was not until the school as institution had been introduced that education came to be governed by the principles of the division of labour and took over the function of the selection and creation of privilege. This has led to an alientation of school leavers from productive work. The educational system as a whole can no longer support those societal tasks that require creativity and development. Following a phase of quantitative expansion, the third part points out that African educational policy is currently making great efforts to give the educational system a qualitative reorientation towards the real needs of African societies. The fourth part describes the detachment from Euro-American strategies of development and innovation, and the revaluation of elements of traditional education. Taking as an example the programme, `Ecole du peuple', which aims to reorganise the educational system of the People's Republic of the Congo from pre-school to university, the difficulties of such an undertaking are investigated.

Reappraisal of the envenoming capacity of Euchambersia mirabilis (Therapsida, Therocephalia) using μCT-scanning techniques

PubMed Central

Norton, Luke A.; Manger, Paul R.; Rubidge, Bruce S.

2017-01-01

Euchambersia mirabilis is an iconic species of Permo-Triassic therapsid because of its unusually large external maxillary fossa linked through a sulcus to a ridged canine. This anatomy led to the commonly accepted conclusion that the large fossa accommodated a venom gland. However, this hypothesis remains untested so far. Here, we conducted a μCT scan assisted reappraisal of the envenoming capacity of Euchambersia, with a special focus on the anatomy of the maxillary fossa and canines. This study shows that the fossa, presumably for the venom-producing gland, is directly linked to the maxillary canal, which carries the trigeminal nerve (responsible for the sensitivity of the face). The peculiar anatomy of the maxillary canal suggests important reorganisation in the somatosensory system and that a ganglion could possibly have been present in the maxillary fossa instead of a venom gland. Nevertheless, the venom gland hypothesis is still preferred since we describe, for the first time, the complete crown morphology of the incisiform teeth of Euchambersia, which strongly suggests that the complete dentition was ridged. Therefore Euchambersia manifests evidence of all characteristics of venomous animals: a venom gland (in the maxillary fossa), a mechanism to deliver the venom (the maxillary canal and/or the sulcus located ventrally to the fossa); and an apparatus with which to inflict a wound for venom delivery (the ridged dentition).

Acute immobilisation facilitates premotor preparatory activity for the non-restrained hand when facing grasp affordances.

Use and non-use of body parts during goal-directed action are major forces driving reorganisation of neural processing. We investigated changes in functional brain activity resulting from acute short-term immobilisation of the dominant right hand. Informed by the concept of object affordances, we predicted that the presence or absence of a limb restraint would influence the perception of graspable objects in a laterally specific way. Twenty-three participants underwent fMRI scanning during a passive object-viewing task before the intervention as well as with and without wearing an orthosis. The right dorsal premotor cortex and the left cerebellum were more strongly activated when the handle of an object was oriented towards the left hand while the right hand was immobilised compared with a situation where the hand was not immobilised. The cluster in the premotor cortex showing an interaction between condition (with restraint, without restraint) and stimulus action side (right vs. left) overlapped with the general task vs. baseline contrast prior to the intervention, confirming its functional significance for the task. These results show that acute immobilisation of the dominant right hand leads to rapid changes of the perceived affordance of objects. We conclude that changes in action requirements lead to almost instantaneous changes in functional activation patterns, which in turn may trigger structural cortical plasticity. Copyright © 2014.

Fast electron transfer through a single molecule natively structured redox protein

The electron transfer properties of proteins are normally measured as molecularly averaged ensembles. Through these and related measurements, proteins are widely regarded as macroscopically insulating materials. Using scanning tunnelling microscopy (STM), we present new measurements of the conductance through single-molecules of the electron transfer protein cytochrome b562 in its native conformation, under pseudo-physiological conditions. This is achieved by thiol (SH) linker pairs at opposite ends of the molecule through protein engineering, resulting in defined covalent contact between a gold surface and a platinum-iridium STM tip. Two different orientations of the linkers were examined: a long-axis configuration (SH-LA) and a short-axis configuration (SH-SA). In each case, the molecular conductance could be `gated' through electrochemical control of the heme redox state. Reproducible and remarkably high conductance was observed in this relatively complex electron transfer system, with single-molecule conductance values peaking around 18 nS and 12 nS for the SH-SA and SH-LA cytochrome b562 molecules near zero electrochemical overpotential. This strongly points to the important role of the heme co-factor bound to the natively structured protein. We suggest that the two-step model of protein electron transfer in the STM geometry requires a multi-electron transfer to explain such a high conductance. The model also yields a low value for the reorganisation energy, implying that solvent reorganisation is largely absent.The electron transfer properties of proteins are normally measured as molecularly averaged ensembles.

Background Emergency departments (EDs) are increasingly overcrowded by walk-in patients. However, little is known about health-economic consequences resulting from long waiting times and inefficient use of specialised resources. We have evaluated a quality improvement project of a Swiss urban hospital: In 2009, a triage system and a hospital-associated primary care unit with General Practitioners (H-GP-unit) were implemented beside the conventional hospital ED. This resulted in improved medical service provision with reduced process times and more efficient diagnostic testing. We now report on health-economic effects. Methods From the hospital perspective, we performed a cost comparison study analysing treatment costs in the old emergency model (ED, only) versus treatment costs in the new emergency model (triage plus ED plus H-GP-unit) from 2007 to 2011. Hospital cost accounting data were applied. All consecutive outpatient emergency contacts were included for 1 month in each follow-up year. Results The annual number of outpatient emergency contacts increased from n=10 440 (2007; baseline) to n=16 326 (2011; after intervention), reflecting a general trend. In 2007, mean treatment costs per outpatient were €358 (95% CI 342 to 375). Until 2011, costs increased in the ED (€423 (396 to 454)), but considerably decreased in the H-GP-unit (€235 (221 to 250)). Compared with 2007, the annual local budget spent for treatment of 16 326 patients in 2011 showed cost reductions of €417 600 (27 200 to 493 600) after adjustment for increasing patient numbers. Conclusions From the health-economic point of view, our new service model shows ‘dominance’ over the old model: While quality of service provision improved (reduced waiting times; more efficient resource use in the H-GP-unit), treatment costs sustainably decreased against the secular trend of increase.

Mapping attractor fields in face space: the atypicality bias in face recognition.

PubMed

Tanaka, J; Giles, M; Kremen, S; Simon, V

1998-09-01

A familiar face can be recognized across many changes in the stimulus input. In this research, the many-to-one mapping of face stimuli to a single face memory is referred to as a face memory's 'attractor field'. According to the attractor field approach, a face memory will be activated by any stimuli falling within the boundaries of its attractor field. It was predicted that by virtue of its location in a multi-dimensional face space, the attractor field of an atypical face will be larger than the attractor field of a typical face. To test this prediction, subjects make likeness judgments to morphed faces that contained a 50/50 contribution from an atypical and a typical parent face. The main result of four experiments was that the morph face was judged to bear a stronger resemblance to the atypical face parent than the typical face parent. The computational basis of the atypicality bias was demonstrated in a neural network simulation where morph inputs of atypical and typical representations elicited stronger activation of atypical output units than of typical output units. Together, the behavioral and simulation evidence supports the view that the attractor fields of atypical faces span over a broader region of face space that the attractor fields of typical faces.

The effect of face-to-face teaching on student knowledge and satisfaction in an undergraduate neuroanatomy course.

Whillier, Stephney; Lystad, Reidar P

2013-01-01

The total number of anatomy teaching hours has declined in medical courses worldwide. Conversely, face-to-face teaching in undergraduate neuroanatomy at Macquarie University increased by 50% in 2011. Our aim was to investigate whether this influenced student performance and overall satisfaction with the course. One hundred eighty-one students consented to participate in this study. A questionnaire was administered to rate the course, and final grades from the old and new unit cohorts were compared. The old and new unit cohorts did not differ in their final grades (P = 0.249). However, the new unit cohort rated their knowledge of the material higher compared to the old unit cohort (P = 0.013), and reported higher levels of satisfaction with the course (P < 0.001). In an era in which teaching time for anatomy has been reduced at tertiary institutions, and there is much lamenting of the effect this will have, there is a paucity of literature on whether the decrease really influences neuroanatomical knowledge. This is the first study, to the best of our knowledge, to show that an increase in total face-to-face teaching hours does not improve student grades, but does increase student satisfaction with the course. © 2012 American Association of Anatomists.

Transnational tobacco companies (TTCs) may respond to processes of regional trade integration both by acting politically to influence policy and by reorganising their own operations. The Central American Common Market (CACM) was reinvigorated in the 1990s, reflecting processes of regional trade liberalisation in Latin America and globally. This study aimed to ascertain how British American Tobacco (BAT), which dominated the markets of the CACM, sought to influence policy towards it by member country governments and how the CACM process impacted upon BAT's operations. The study analysed internal tobacco industry documents released as a result of litigation in the US and available from the online Legacy Tobacco Documents Library at http://legacy.library.ucsf.edu/. Documents were retrieved by searching the BAT collection using key terms in an iterative process. Analysis was based on an interpretive approach involving a process of attempting to understand the meanings of individual documents and relating these to other documents in the set, identifying the central themes of documents and clusters of documents, contextualising the documentary data, and choosing representative material in order to present findings. Utilising its multinational character, BAT was able to act in a coordinated way across the member countries of the CACM to influence tariffs and taxes to its advantage. Documents demonstrate a high degree of access to governments and officials. The company conducted a coordinated, and largely successful, attempt to keep external tariff rates for cigarettes high and to reduce external tariffs for key inputs, whilst also influencing the harmonisation of excise taxes between countries. Protected by these high external tariffs, it reorganised its own operations to take advantage of regional economies of scale. In direct contradiction to arguments presented to CACM governments that affording the tobacco industry protection via high cigarette tariffs would safeguard employment, the company's regional reorganisation involved the loss of hundreds of jobs. Regional integration organisations and their member states should be aware of the capacity of TTCs to act in a coordinated transnational manner to influence policy in their own interests, and coordinate their own public health and tax policies in a similarly effective way.

Pilot study of the cortical correlates and clinical effects of passive ankle mobilisation in children with upper motorneuron lesions.

2015-01-01

Upper motoreuron lesions (UML) affects people of all ages and conditions and is a major cause of disability in the young. Whereas active exercise is recognised as paramount to restore the lost motor functions, passive mobilisation of the affected limbs is regarded as a means to safeguard muscular tissue properties during a period of disuse and lack of voluntary control, which often characterises the acute and sub-acute phases. The purpose of the present work is to study the cortical reactivity in UML patients who are treated for two weeks with a robotic passive ankle mobiliser, and the clinical effects of this treatment. The rationale is that, if passive mobilisation can affect positively the functional reorganisation at a cortical level, it could be proposed as a suitable tool to maintain afferentation and guide central nervous remapping, thus bridging the period of time when active exercise is impossible due to acute paresis. Preliminary results on 7 patients (aged 15.35±4.36) showed that this therapy is very well tolerated and suggest that its application could specifically improve ankle PROM and plantarflexor muscle length. EEG data showed improved desynchronisation in at least one frequency band in 3 patients of the study, thus confirming the effects of passive mobilisation on the cortical re-organisation of some patients having UML.

[Adaptation of control mechanisms involved in upright undisturbed stance maintenance during prolonged darkness].

PubMed

Rougier, P

2003-04-01

To assess to which extent the non visual somato-sensorial information may, through a recalibration process, induce a reorganisation by the central nervous system to control undisturbed upright stance. Ten healthy adults were placed in complete darkness for a 24 min period. Their postural performance was recorded through a force platform on which they were required to stand still at regular intervals. Centre of Pressure (CP) displacements, recorded from the platform, were modelled as fractional brownian motion. Through this analysis, one may objectively assess from which distance and for how long the corrective process is initiated with the aim of slowing and retrace its steps. In addition, the degree to which the CP trajectories are successively controlled was determined. Once in complete darkness, an increase of the mean time intervals (Delta(t)) before the corrective process intervenes was observed, the effect being mostly significant for the mediolateral direction. In parallel, the mean distances covered at this Delta(t) were slightly affected for both mediolateral and anteroposterior directions. Lastly, the degree to which the CP trajectories are controlled tended to decrease. These data suggest a reorganisation of the control mechanisms called into play for maintaining an undisturbed upright stance, thus implying participation of the central nervous system. This short-term adaptation is discussed on the basis of our knowledge of long term adaptations previously observed in blind individuals, and also in a rehabilitation perspective.

Epithelial morphogenesis involves a dramatic reorganisation of the microtubule cytoskeleton. How this complex process is controlled at the molecular level is still largely unknown. Here, we report that the centrosomal microtubule (MT)-binding protein CAP350 localises at adherens junctions in epithelial cells. By two-hybrid screening, we identified a direct interaction of CAP350 with the adhesion protein α-catenin that was further confirmed by co-immunoprecipitation experiments. Block of epithelial cadherin (E-cadherin)-mediated cell-cell adhesion or α-catenin depletion prevented CAP350 localisation at cell-cell junctions. Knocking down junction-located CAP350 inhibited the establishment of an apico-basal array of microtubules and impaired the acquisition of columnar shape in Madin-Darby canine kidney II (MDCKII) cells grown as polarised epithelia. Furthermore, MDCKII cystogenesis was also defective in junctional CAP350-depleted cells. CAP350-depleted MDCKII cysts were smaller and contained either multiple lumens or no lumen. Membrane polarity was not affected, but cortical microtubule bundles did not properly form. Our results indicate that CAP350 may act as an adaptor between adherens junctions and microtubules, thus regulating epithelial differentiation and contributing to the definition of cell architecture. We also uncover a central role of α-catenin in global cytoskeleton remodelling, in which it acts not only on actin but also on MT reorganisation during epithelial morphogenesis.

2016-01-01

Background An integrated chronic disease management (ICDM) model consisting of four components (facility reorganisation, clinical supportive management, assisted self-supportive management and strengthening of support systems and structures outside the facility) has been implemented across 42 primary health care clinics in South Africa with a view to improve the operational efficiency and patient clinical outcomes. Aim The aim of this study was to assess the sustainability of the facility reorganisation and clinical support components 18 months after the initiation. Setting The study was conducted at 37 of the initiating clinics across three districts in three provinces of South Africa. Methods The National Health Service (NHS) Institute for Innovation and Improvement Sustainability Model (SM) self-assessment tool was used to assess sustainability. Results Bushbuckridge had the highest mean sustainability score of 71.79 (95% CI: 63.70–79.89) followed by West Rand Health District (70.25 (95% CI: 63.96–76.53)) and Dr Kenneth Kaunda District (66.50 (95% CI: 55.17–77.83)). Four facilities (11%) had an overall sustainability score of less than 55. Conclusion The less than optimal involvement of clinical leadership (doctors), negative staff behaviour towards the ICDM, adaptability or flexibility of the model to adapt to external factors and infrastructure limitation have the potential to negatively affect the sustainability and scale-up of the model.

Barbato, Angelo; Civenti, Graziella; D'Avanzo, Barbara

2017-06-01

Residential mental health services grew steadily since 2000 in Italy. A reorganisation of residential facilities was implemented in 2007 in Lombardy, introducing supported housing in addition to staffed facilities. We compare the provision and characteristics of residential facilities in the 2007 and 2016. In 2007 there were 3462 beds (35.9/100,000 population) in 276 facilities. In 2016 beds were 4783 (47.8/100,000) in 520 facilities. The increase were unevenly distributed in the public and private sector, and the overall increase was due to a higher increase in the private sector. 72% of beds were in highly supervised facilities in 2007 and 66% in 2016. The public sector managed more facilities with a rehabilitation goal, while the private sector more for long-term accommodation. Mean numbers of beds were higher in facilities managed by the private sector in both years. The 2007 reorganisation and the stop to opening new facilities in the last years were not enough to correct the imbalance between highly supervised and flexible solutions. A wider and more diverse offer might have triggered off an increased demand, rather than a more rational use. Given the costs of highly staffed facilities, and the risk of reproducing custodial models, close evaluation of the use of residential facilities should inform policies.

Functional-structural reorganisation of the neuronal network for auditory perception in subjects with unilateral hearing loss: Review of neuroimaging studies.

PubMed

Heggdal, Peder O Laugen; Brännström, Jonas; Aarstad, Hans Jørgen; Vassbotn, Flemming S; Specht, Karsten

2016-02-01

This paper aims to provide a review of studies using neuroimaging to measure functional-structural reorganisation of the neuronal network for auditory perception after unilateral hearing loss. A literature search was performed in PubMed. Search criterions were peer reviewed original research papers in English completed by the 11th of March 2015. Twelve studies were found to use neuroimaging in subjects with unilateral hearing loss. An additional five papers not identified by the literature search were provided by a reviewer. Thus, a total of 17 studies were included in the review. Four different neuroimaging methods were used in these studies: Functional magnetic resonance imaging (fMRI) (n = 11), diffusion tensor imaging (DTI) (n = 4), T1/T2 volumetric images (n = 2), magnetic resonance spectroscopy (MRS) (n = 1). One study utilized two imaging methods (fMRI and T1 volumetric images). Neuroimaging techniques could provide valuable information regarding the effects of unilateral hearing loss on both auditory and non-auditory performance. fMRI-studies showing a bilateral BOLD-response in patients with unilateral hearing loss have not yet been followed by DTI studies confirming their microstructural correlates. In addition, the review shows that an auditory modality-specific deficit could affect multi-modal brain regions and their connections. Copyright © 2015 Elsevier B.V. All rights reserved.

2017-01-01

The authors' aim was to investigate gender and cultural differences in the attributions used to determine causality for hypothetical public and private face-to-face and cyber victimization scenarios among 3,432 adolescents (age range = 11-15 years; 49% girls) from China, Cyprus, the Czech Republic, India, Japan, and the United States, while accounting for their individualism and collectivism. Adolescents completed a questionnaire on cultural values and read four hypothetical victimization scenarios, including public face-to-face victimization, public cyber victimization, private face-to-face victimization, and private cyber victimization. After reading the scenarios, they rated different attributions (i.e., self-blame, aggressor-blame, joking, normative, conflict) according to how strongly they believed the attributions explained why victimization occurred. Overall, adolescents reported that they would utilize the attributions of self-blame, aggressor-blame, and normative more for public forms of victimization and face-to-face victimization than for private forms of victimization and cyber victimization. Differences were found according to gender and country of origin as well. Such findings underscore the importance of delineating between different forms of victimization when examining adolescents' attributions.

Jansen, Arild; Løvdal, Einar

This study examines the reorganisation of the administration of admission to higher education in Norway, which has also included the development of a nationwide, ICT-based case handling system. This reform process was initiated out of the need to provide politicians with information for control and regulatory purposes, and the reform resulted in a centralised management information system. This system, however, has evolved into a coordinated but also partly locally delegated decision-making instrument which processes most of the applications for admission to higher education in Norway.

We hereby present the new class of ionic liquid systems in which lithium salt is introduced into the solution as a lithium cation−glyme solvate. This modification leads to the reorganisation of solution structure, which entails release of free mobile lithium cation solvate and hence leads to the significant enhancement of ionic conductivity and lithium cation transference numbers. This new approach in composing electrolytes also enables even three-fold increase of salt concentration in ionic liquids. PMID:27767069

Substrate specificity in enzymatic fluorination. The fluorinase from Streptomyces cattleya accepts 2′-deoxyadenosine substrates†

2012-01-01

The fluorinase enzyme from Streptomyces cattleya displays an unusual ability in biocatalysis in that it forms a C–F bond. We now report that the enzyme will accept 2′-deoxyadenosine in place of adenosine substrates, and structural evidence reveals a reorganisation in hydrogen bonding to accommodate this substrate series. It emerges from this study that the enzyme does not require a planar ribose conformation of the substrate to catalyse C–F bond formation. PMID:16604208

Right-Wing Politicians Prefer the Emotional Left

Thomas, Nicole A.; Loetscher, Tobias; Clode, Danielle; Nicholls, Michael E. R.

2012-01-01

Physiological research suggests that social attitudes, such as political beliefs, may be partly hard-wired in the brain. Conservatives have heightened sensitivity for detecting emotional faces and use emotion more effectively when campaigning. As the left face displays emotion more prominently, we examined 1538 official photographs of conservative and liberal politicians from Australia, Canada, the United Kingdom and the United States for an asymmetry in posing. Across nations, conservatives were more likely than liberals to display the left cheek. In contrast, liberals were more likely to face forward than were conservatives. Emotion is important in political campaigning and as portraits influence voting decisions, conservative politicians may intuitively display the left face to convey emotion to voters. PMID:22567166

Evidence for view-invariant face recognition units in unfamiliar face learning.

PubMed

Etchells, David B; Brooks, Joseph L; Johnston, Robert A

2017-05-01

Many models of face recognition incorporate the idea of a face recognition unit (FRU), an abstracted representation formed from each experience of a face which aids recognition under novel viewing conditions. Some previous studies have failed to find evidence of this FRU representation. Here, we report three experiments which investigated this theoretical construct by modifying the face learning procedure from that in previous work. During learning, one or two views of previously unfamiliar faces were shown to participants in a serial matching task. Later, participants attempted to recognize both seen and novel views of the learned faces (recognition phase). Experiment 1 tested participants' recognition of a novel view, a day after learning. Experiment 2 was identical, but tested participants on the same day as learning. Experiment 3 repeated Experiment 1, but tested participants on a novel view that was outside the rotation of those views learned. Results revealed a significant advantage, across all experiments, for recognizing a novel view when two views had been learned compared to single view learning. The observed view invariance supports the notion that an FRU representation is established during multi-view face learning under particular learning conditions.

Quantifying the adaptive cycle

2015-01-01

The adaptive cycle was proposed as a conceptual model to portray patterns of change in complex systems. Despite the model having potential for elucidating change across systems, it has been used mainly as a metaphor, describing system dynamics qualitatively. We use a quantitative approach for testing premises (reorganisation, conservatism, adaptation) in the adaptive cycle, using Baltic Sea phytoplankton communities as an example of such complex system dynamics. Phytoplankton organizes in recurring spring and summer blooms, a well-established paradigm in planktology and succession theory, with characteristic temporal trajectories during blooms that may be consistent with adaptive cycle phases. We used long-term (1994–2011) data and multivariate analysis of community structure to assess key components of the adaptive cycle. Specifically, we tested predictions about: reorganisation: spring and summer blooms comprise distinct community states; conservatism: community trajectories during individual adaptive cycles are conservative; and adaptation: phytoplankton species during blooms change in the long term. All predictions were supported by our analyses. Results suggest that traditional ecological paradigms such as phytoplankton successional models have potential for moving the adaptive cycle from a metaphor to a framework that can improve our understanding how complex systems organize and reorganize following collapse. Quantifying reorganization, conservatism and adaptation provides opportunities to cope with the intricacies and uncertainties associated with fast ecological change, driven by shifting system controls. Ultimately, combining traditional ecological paradigms with heuristics of complex system dynamics using quantitative approaches may help refine ecological theory and improve our understanding of the resilience of ecosystems.

To investigate the neuronal activation pattern underlying the effects of mirror illusion in children/adolescents with normal motor development and in children/adolescents with hemiparesis and preserved contralateral corticospinal organisation. The type of cortical reorganisation was classified according to results of transcranial magnetic stimulation. Only subjects with congenital lesions and physiological contralateral cortical reorganisation were included. Functional magnetic resonance imaging was performed to investigate neuronal activation patterns with and without a mirror box. Each test consisted of a unimanual and a bimanual motor task. Seven children/adolescents with congenital hemiparesis (10-20 years old, three boys and four girls) and seven healthy subjects (8-17 years old, four boys and three girls) participated in this study. In the bimanual experiment, children with hemiparesis showed a significant effect of the mirror illusion (p<0.001 at voxel level, family-wise error corrected at cluster level) in the dorsolateral prefrontal cortex and anterior cingulate cortex of the affected and unaffected hemispheres, respectively. No significant effects of the mirror illusion were observed in unimanual experiments and in healthy participants. Mirror illusion in children/adolescents with hemiparesis leads to activation of brain areas involved in visual conflict detection and cognitive control to resolve this conflict. This effect is observed only in bimanual training. We consider that for mirror therapy in children and adolescents with hemiparesis a bimanual approach is more suitable than a unimanual approach.

Expectation and Surprise Determine Neural Population Responses in the Ventral Visual Stream

PubMed Central

Egner, Tobias; Monti, Jim M.; Summerfield, Christopher

2014-01-01

Visual cortex is traditionally viewed as a hierarchy of neural feature detectors, with neural population responses being driven by bottom-up stimulus features. Conversely, “predictive coding” models propose that each stage of the visual hierarchy harbors two computationally distinct classes of processing unit: representational units that encode the conditional probability of a stimulus and provide predictions to the next lower level; and error units that encode the mismatch between predictions and bottom-up evidence, and forward prediction error to the next higher level. Predictive coding therefore suggests that neural population responses in category-selective visual regions, like the fusiform face area (FFA), reflect a summation of activity related to prediction (“face expectation”) and prediction error (“face surprise”), rather than a homogenous feature detection response. We tested the rival hypotheses of the feature detection and predictive coding models by collecting functional magnetic resonance imaging data from the FFA while independently varying both stimulus features (faces vs houses) and subjects’ perceptual expectations regarding those features (low vs medium vs high face expectation). The effects of stimulus and expectation factors interacted, whereby FFA activity elicited by face and house stimuli was indistinguishable under high face expectation and maximally differentiated under low face expectation. Using computational modeling, we show that these data can be explained by predictive coding but not by feature detection models, even when the latter are augmented with attentional mechanisms. Thus, population responses in the ventral visual stream appear to be determined by feature expectation and surprise rather than by stimulus features per se. PMID:21147999

A process is described for adding electrolyte to a fuel cell stack, the stack comprising sheet-like elements defining a plurality of fuel cell units disposed one atop the other in abutting relationship, the units defining a substantially flat, vertically extending face, each unit including a cell comprising a pair of sheet-like spaced apart gas porous electrodes with a porous matrix layer sandwiched therebetween for retaining electrolyte during cell operation, each unit also including a sheet-like substantially non-porous separator, the separator being sandwiched between the cells of adjacent units. The improvement described here consists of: extending at least one of themore » sheet-like elements of each of a plurality of the fuel cell units outwardly from the stack face to define horizontal tabs disposed one above the other; depositing dilute electrolyte directly from electrolyte supply means upon substantially the full length, parallel to the stack face, of at least the uppermost tab, the tabs being constructed and arranged such that at least a portion of the deposited electrolyte cascades from tab to tab and down the face of the stack, the deposited electrolyte being absorbed by capillary action into the elements of the stack, the step of depositing continuing until all of the electrodes and matrix layers of the stack are fully saturated with the dilute electrolyte; and thereafter evaporating liquid from the saturated elements under controlled conditions of humidity and temperature until the stack has a desired electrolyte volume and electrolyte concentration therein.« less

Face-to-face handoff: improving transfer to the pediatric intensive care unit after cardiac surgery.

The goal was to develop and implement a comprehensive, primarily face-to-face handoff process that begins in the operating room and concludes at the bedside in the intensive care unit (ICU) for pediatric patients undergoing congenital heart surgery. Involving all stakeholders in the planning phase, the framework of the handoff system encompassed a combination of a formalized handoff tool, focused process steps that occurred prior to patient arrival in the ICU, and an emphasis on face-to-face communication at the conclusion of the handoff. The final process was evaluated by the use of observer checklists to examine quality metrics and timing for all patients admitted to the ICU following cardiac surgery. The process was found to improve how various providers view the efficiency of handoff, the ease of asking questions at each step, and the overall capability to improve patient care regardless of overall surgical complexity. © 2014 by the American College of Medical Quality.

Tungsten was selected as armor material for the helium-cooled divertor in future DEMO-type fusion reactors and fusion power plants. After realizing the design and testing of them under cyclic thermal loads of up to ~14 MW m-2, the tungsten divertor plasma-facing units were examined by metallography; they revealed failures such as cracks at the thermal loaded and as-machined surfaces, as well as degradation of the brazing layers. Furthermore, in order to optimize the machining processes, the quality of tungsten surfaces prepared by turning, milling and using a diamond cutting wheel were examined. This paper presents a metallographic examination of the tungsten plasma-facing units as well as technical studies and the characterization on machining of tungsten and alternative brazing joints.

Sustained health-economic effects after reorganisation of a Swiss hospital emergency centre: a cost comparison study.

2014-10-01

Emergency departments (EDs) are increasingly overcrowded by walk-in patients. However, little is known about health-economic consequences resulting from long waiting times and inefficient use of specialised resources. We have evaluated a quality improvement project of a Swiss urban hospital: In 2009, a triage system and a hospital-associated primary care unit with General Practitioners (H-GP-unit) were implemented beside the conventional hospital ED. This resulted in improved medical service provision with reduced process times and more efficient diagnostic testing. We now report on health-economic effects. From the hospital perspective, we performed a cost comparison study analysing treatment costs in the old emergency model (ED, only) versus treatment costs in the new emergency model (triage plus ED plus H-GP-unit) from 2007 to 2011. Hospital cost accounting data were applied. All consecutive outpatient emergency contacts were included for 1 month in each follow-up year. The annual number of outpatient emergency contacts increased from n=10 440 (2007; baseline) to n=16 326 (2011; after intervention), reflecting a general trend. In 2007, mean treatment costs per outpatient were €358 (95% CI 342 to 375). Until 2011, costs increased in the ED (€423 (396 to 454)), but considerably decreased in the H-GP-unit (€235 (221 to 250)). Compared with 2007, the annual local budget spent for treatment of 16 326 patients in 2011 showed cost reductions of €417 600 (27 200 to 493 600) after adjustment for increasing patient numbers. From the health-economic point of view, our new service model shows 'dominance' over the old model: While quality of service provision improved (reduced waiting times; more efficient resource use in the H-GP-unit), treatment costs sustainably decreased against the secular trend of increase.

Recognizing Action Units for Facial Expression Analysis

Most automatic expression analysis systems attempt to recognize a small set of prototypic expressions, such as happiness, anger, surprise, and fear. Such prototypic expressions, however, occur rather infrequently. Human emotions and intentions are more often communicated by changes in one or a few discrete facial features. In this paper, we develop an Automatic Face Analysis (AFA) system to analyze facial expressions based on both permanent facial features (brows, eyes, mouth) and transient facial features (deepening of facial furrows) in a nearly frontal-view face image sequence. The AFA system recognizes fine-grained changes in facial expression into action units (AUs) of the Facial Action Coding System (FACS), instead of a few prototypic expressions. Multistate face and facial component models are proposed for tracking and modeling the various facial features, including lips, eyes, brows, cheeks, and furrows. During tracking, detailed parametric descriptions of the facial features are extracted. With these parameters as the inputs, a group of action units (neutral expression, six upper face AUs and 10 lower face AUs) are recognized whether they occur alone or in combinations. The system has achieved average recognition rates of 96.4 percent (95.4 percent if neutral expressions are excluded) for upper face AUs and 96.7 percent (95.6 percent with neutral expressions excluded) for lower face AUs. The generalizability of the system has been tested by using independent image databases collected and FACS-coded for ground-truth by different research teams. PMID:25210210

NHS politics. Winging it.

PubMed

Dewar, Steve; Chantler, Cyril

2002-03-14

At present, NHS managers are highly constrained, suffering excessive regulation and central control. More autonomy for trusts would mean fewer directives and less performance management. Giving trusts a new organisational form, such as a public interest company or foundation hospital, might be reinvigorating and would not involve further reorganisation. These new freedoms should be accompanied by new accountabilities, not solely to politicians but to independent NHS regulators, local communities and patients. Devolved power and greater patient choice could produce a more responsive NHS. Its potential needs to be explored through experimentation and evaluation.

Candelise, Livia; Gattinoni, Monica; Bersano, Anna

2015-01-01

Although several valid approaches exist to measure the number and the quality of acute stroke units, only few studies tested their reliability. This study is aimed at establishing whether the telephone administration of the PROject of Stroke unIt ITaly (PROSIT) audit questionnaire is reliable compared with direct face-to-face interview. Forty-three medical leaders in charge of in-hospital stroke services were interviewed twice using the same PROSIT questionnaire with 2 different modalities. First, the interviewers approached the medical leaders by telephone. Thereafter, they went to the hospital site and performed a direct face-to-face interview. Six independent couples of trained researchers conducted the audit interviews. The degree of intermodality agreement was measured with kappa statistic. We found a perfect agreement for stroke units identification between the 2 different audit modalities (K = 1.00; standard error [SE], 1.525). The agreement was also very good for stroke dedicated beds (K = 1.00; SE, 1.525) and dedicated personnel (K = 1.00; SE, 1.525), which are the 2 components of stroke unit definition. The agreement was lower for declared in use process of care and availability of diagnostic investigations. The telephone audit can be used for monitoring stroke unit structures. It is more rapid, less expensive, and can repeatedly be used at appropriate intervals. However, a reliable description of the process of care and diagnostic investigations indicators should be obtained by either local site audit visit or prospective stroke register based on individual patient data.

Postdoctoral training in clinical neuropsychology in America: how did we get here and where do recent applicants suggest we go next?

PubMed

Bodin, Doug; Butts, Alissa M; Grote, Christopher L

2016-11-01

The United States appears to be the only country which typically requires completion of a two-year postdoctoral fellowship for one to be considered competent to practice clinical neuropsychology. We review the history of how this came to be in the United States. Further, we describe obstacles that postdoctoral trainees face during this stage of training. We first describe the most significant events leading to the requirement of a two-year fellowship in clinical neuropsychology. Next, we describe factors that trainees face when selecting and completing postdoctoral training. Finally, we review the results of the most recent annual survey of applicants for postdoctoral training to measure their experiences. Postdoctoral training in the United States is a relatively recent requirement in neuropsychology. Trainees face many obstacles when obtaining a postdoctoral position some of which can be addressed by the field. Training in Clinical Neuropsychology in the United States has evolved considerably over at least the last 45 or so years to the point that a two-year postdoctoral fellowship is now required for one to be a candidate for board certification through the American Board of Clinical Neuropsychology. We review many of the challenges that postdoctoral trainees face and provide survey data to describe their experiences and preferences.

Developing and applying quantitative skills maps for STEM curricula, with a focus on different modes of learning

NASA Astrophysics Data System (ADS)

Reid, Jackie; Wilkes, Janelle

2016-08-01

Mapping quantitative skills across the science, technology, engineering and mathematics (STEM) curricula will help educators identify gaps and duplication in the teaching, practice and assessment of the necessary skills. This paper describes the development and implementation of quantitative skills mapping tools for courses in STEM at a regional university that offers both on-campus and distance modes of study. Key elements of the mapping project included the identification of key graduate quantitative skills, the development of curriculum mapping tools to record in which unit(s) and at what level of attainment each quantitative skill is taught, practised and assessed, and identification of differences in the way quantitative skills are developed for on-campus and distance students. Particular attention is given to the differences that are associated with intensive schools, which consist of concentrated periods of face-to-face learning over a three-four day period, and are available to distance education students enrolled in STEM units. The detailed quantitative skills mapping process has had an impact on the review of first-year mathematics units, resulted in crucial changes to the curriculum in a number of courses, and contributed to a more integrated approach, and a collective responsibility, to the development of students' quantitative skills for both face-to-face and online modes of learning.

2002-01-01

Problem Patients with jaundice require rapid diagnosis and treatment, yet such patients are often subject to delay. Design An open referral, rapid access jaundice clinic was established by reorganisation of existing services and without the need for significant extra resources. Background and setting A large general hospital in a largely rural and geographically isolated area. Key measures for improvement Waiting times for referral, consultation, diagnosis, and treatment, length of stay in hospital, and general practitioners' and patients' satisfaction with the service. Strategies for change Referrals were made through a 24 hour telephone answering machine and fax line. Initial assessment of patients was carried out by junior staff as part of their working week. Dedicated ultrasonography appointments were made available. Effects of change Of 107 patients seen in the first year of the service, 62 had biliary obstruction. The mean time between referral and consultation was 2.5 days. Patients who went on to endoscopic retrograde cholangiopancreatography waited 5.7 days on average. The mean length of stay in hospital in the 69 patients who were admitted was 6.1 days, compared with 11.5 days in 1996, as shown by audit data. Nearly all the 36 general practices (95%) and the 30 consecutive patients (97%) that were surveyed rated the service as above average or excellent. Lessons learnt An open referral, rapid access service for patients with jaundice can shorten time to diagnosis and treatment and length of stay in hospital. These improvements can occur through the reorganisation of existing services and with minimal extra cost. PMID:12142314

Acute functional reorganisation of the human motor cortex during resection of central lesions: a study using intraoperative brain mapping

PubMed Central

Duffau, H

2001-01-01

OBJECTIVES—Brain plasticity is supposed to allow the compensation of motor function in cases of rolandic lesion. The aim was to analyse the mechanisms of functional reorganisation during surgery in the central area.
METHODS—A motor brain mapping was performed in three right handed patients without any neurological deficit, operated on for a slow growing lesion near the rolandic region (two precentral resected under general anaesthesia and one retrocentral removed under local anaesthesia to allow also sensory mapping) using intraoperative direct electrical stimulations (5 mm space tips bipolar stimulator probe, biphasic square wave pulse current: 1 ms/phase, 60 Hz, 4 to 18mA).
RESULTS—For each patient, the motor areas of the hand and forearm in the primary motor cortex (M1) were identified before and after lesion removal with the same stimulation parameters: the same eloquent sites were found, plus the appearance after resection of additional sites in M1 inducing the same movement during stimulations as the previous areas.
CONCLUSIONS—Multiple cortical representations for hand and forearm movements in M1 seem to exist. In addition, the results demonstrate the short term capacity of the brain to make changes in local motor maps, by sudden unmasking after tumour resection of a second redundant site participating in the same movement. Finally, it seems not necessary for the whole of the redundant sites to be functional to provide normal movement, a concept with potential implications for surgery within the central region.

Harada, Takaaki; Lincoln, Stephen F; Kee, Tak W

2016-10-12

Curcumin is a yellow polyphenol with multiple medicinal effects. These effects, however, are limited due to its poor aqueous stability and solubility. A hydrogel of 3% octadecyl randomly substituted polyacrylate (PAAC18) has been shown to provide high aqueous stability for curcumin under physiological conditions, offering a route for photodynamic therapy. In this study, the excited-state photophysics of curcumin in the PAAC18 hydrogel is investigated using a combination of femtosecond transient absorption and fluorescence upconversion spectroscopy. The transient absorption results reveal a multiexponential decay in the excited-state kinetics with fast (1 ps & 15 ps) and slow (110 ps & ≈5 ns) components. The fast decay component exhibits a deuterium isotope effect with D 2 O in the hydrogel, indicating that the 15 ps decay component is attributable to excited-state intramolecular hydrogen atom transfer of curcumin in the PAAC18 hydrogel. In addition, solvent reorganisation of excited-state curcumin is investigated using multiwavelength femtosecond fluorescence upconversion spectroscopy. The results show that the dominant solvation response (τ = 0.08 ps) is a fast inertial motion owing to the presence of bulk-like water in the vicinity of the hydrophobic octadecyl substituents of the PAAC18 hydrogel. The results also show an additional response with longer time constants of 1 and 6 ps, which is attributable to translational diffusion of confined water molecules in the three-dimensional, cross-linking network of the octadecyl substituents of PAAC18. Overall, we show that excited-state intramolecular hydrogen atom transfer and solvent reorganisation are major photophysical events for curcumin in the PAAC18 hydrogel.

Detachment of the fucoxanthin chlorophyll a/c binding protein (FCP) antenna is not involved in the acclimative regulation of photoprotection in the pennate diatom Phaeodactylum tricornutum.

PubMed

Giovagnetti, Vasco; Ruban, Alexander V

2017-03-01

When grown under intermittent light (IL), the pennate diatom Phaeodactylum tricornutum forms 'super' non-photochemical fluorescence quenching (NPQ) in response to excess light. The current model of diatom NPQ mechanism involves two quenching sites, one of which detaches from photosystem II reaction centres (RCIIs) and aggregates into oligomeric complexes. Here we addressed how antenna reorganisation controls NPQ kinetics in P. tricornutum cells grown under continuous light (CL) and IL. Overall, IL acclimation induced: (i) reorganisation of chloroplasts, containing greater pigment pools without a strongly enhanced operation of the xanthophyll cycle, and (ii) 'super NPQ' causing a remarkable reduction of the chlorophyll excited state lifetime at Fm'. Regardless of different levels of NPQ formed in both culture conditions, its dark recovery was rapid and similar fractions of their antenna uncoupled (~50%). Although antenna detachment relieved excitation pressure, it provided a minor protective contribution equivalent to NPQ~1, while the largest NPQ was 4.4±0.2 (CL) and 13±0.8 (IL). The PSII cross-section decrease took place only at relatively low NPQ values, beyond which the cross-section remained constant whilst NPQ continued to rise. This finding suggests that the energy trapping efficiency of diatom antenna quenchers cannot over-compete that of RCIIs, similarly to what has been observed on higher plants. We conclude that such 'economic photoprotection' operates to flexibly adjust the overall efficiency of diatom light harvesting. Copyright © 2016 Elsevier B.V. All rights reserved.

Extreme multi-basin fluvial flows and their relationship to extra-tropical cyclones

NASA Astrophysics Data System (ADS)

De Luca, Paolo; Hillier, John K.; Wilby, Robert L.; Quinn, Nevil W.; Harrigan, Shaun

2017-04-01

Fluvial floods are typically investigated as 'events' at the single basin scale, thereby implicitly assuming that severe flooding impacts each catchment independently from those nearby. A statistical analysis of the spatio-temporal characteristics of extreme flows in Great Britain (GB), during 1975-2014, is presented. These observations deepen understanding of the processes leading to multi-basin floods and present helpful insights for contingency planning and emergency responders. The largest multi-basin peak flow events within different time windows were identified by counting the number of coincident annual maximum river peak flows (AMAX) across 261 non-nested catchments, using search windows of 1 to 19 days. This showed that up to 107 basins reached their AMAX within the same plateauing 13-day window, draining a total area equivalent to ˜46% of the overall basins considered, which is an equivalent fraction of ˜27% of Great Britain. Such episodes are typically associated with persistent cyclonic atmospheric circulation and saturated ground, combined with short hydrological response times (<48 h) from large contributing basins. The most spatially extensive episodes also tend to coincide with the most severe gales (i.e. extra-tropical cyclones) on a ±0-13 day time-scale. The analysis suggests that multi-basin peak flow events can be characterised by concurrent peak flow AMAX and that the most extreme are driven by very severe gales (VSG). This has implications for emergency response including planning for combined flood-wind impacts (on for example power and communication systems), meaning that the emergency preparedness need to be reorganised in order to face this peril.

Care work in changing welfare states: Nordic care workers' experiences.

PubMed

Trydegård, Gun-Britt

2012-06-01

This article focuses on Nordic eldercare workers and their experiences of working conditions in times of change and reorganisation. In recent years New Public Management-inspired ideas have been introduced to increase efficiency and productivity in welfare services. These reforms have also had an impact on day-to-day care work, which has become increasingly standardized and set out in detailed contracts, leading to time-pressure and an undermining of care workers' professional discretion and autonomy. The empirical data comes from a survey of unionised eldercare workers in home care and residential care in Denmark, Finland, Norway and Sweden ( N  = 2583) and was analysed by bi- and multi-variate methods. The care workers reported that they found their working conditions physically and mentally arduous. They had to a great extent experienced changes for the worse in terms of working conditions and in their opportunity to provide good quality care. In addition, the majority felt they did not receive support from their managers. An alarming finding was that one out of three care workers declared that they had seriously considered quitting their jobs. Care workers with multiple problems at work were much more likely to consider quitting, and the likelihood was increasing with the number of problems reported. Furthermore, care workers lacking support from their managers had double odds of wanting to quit. The Nordic welfare states with growing older populations are facing challenges in retaining care staff in the eldercare services and ensuring they have good working conditions and support in their demanding work.

Modeling the Growth Rates of Tetragonal Lysozyme Crystal Faces

NASA Technical Reports Server (NTRS)

Li, Meirong; Nadarajah, Arunan; Pusey, Marc L.

1998-01-01

The measured macroscopic growth rates of the (110) and (101) faces of tetragonal lysozyme show an unexpectedly complex dependence on the supersaturation. The growth rates decay asymptotically to zero when the supersaturation is lowered to zero and increase rapidly when the supersaturation is increased. When supersaturations are increased still further the growth rates attain a maximum before starting to decrease. However, growth of these crystals is known to proceed by the classical dislocation and 2D nucleation growth mechanisms. This anomaly can be explained if growth is assumed to occur not by monomer units but by lysozyme aggregates. Analysis of the molecular packing of these crystals revealed that they were constructed of strongly bonded 4(sub 3) helices, while weaker bonds were responsible for binding the helices to each other. It follows that during crystal growth the stronger bonds are formed before the weaker ones. Thus, the growth of these crystals could be viewed as a two step process: aggregate growth units corresponding to the 4(sub 3) helix are first formed in the bulk solution by stronger intermolecular bonds and then attached to the crystal face by weaker bonds on dislocation hillocks or 2D islands. This will lead to a distribution of aggregates in the solution with monomers and lower order aggregates being predominant at low supersaturations and higher order aggregates being predominant at high supersaturations. If the crystal grows mostly by higher order aggregates, such as tetramers and octamers, it would explain the anomalous dependence of the growth rates on the supersaturation. Besides the analysis of molecular packing, a comprehensive analysis of the measured (110) and (101) growth rates was also undertaken in this study. The distribution of aggregates in lysozyme nutrient solutions at various solution conditions were determined from reversible aggregation reactions at equilibrium. The supersaturation was defined for each aggregate species with respect to its concentration at saturation in order to apply growth rate models to this process. The measured growth rates were then compared with the predicted ones from several dislocation and 2D nucleation growth models, employing tetramer and octamer growth units in polydisperse solutions and monomer units in monodisperse solutions. For the (110) face, the calculations consistently showed that the measured growth rates followed the expected model relations with octamer growth units. For the (101) face, it is not possible to obtain a clear agreement between the predicted and measured growth rates for a single growth unit as done for the (110) face. However, the calculations do indicate that the average size of the growth unit is between a tetramer and an octamer. This suggests that tetramers, octamers and other intermediate size growth units all participate in the growth process for this face. These calculations show that it is possible to model the macroscopic protein crystal growth rates if the molecular level processes can be account for, particularly protein aggregation processes in the bulk solution. Our recent investigations of tetragonal lysozyme crystals employing high resolution atomic force microscopy scans have further confirmed the growth of these crystals by aggregate growth units corresponding to 4(sub 3) helices.

Challenges and issues facing the future of nursing education: implications for ethnic minority faculty and students.

PubMed

Davis, Sheila P; Davis, Danyetta D

2010-01-01

Current trends in higher education in the United States demand that nursing take stock of how it is prepared or being prepared to face challenges and issues impacting on its future. The intense effort made to attract students to pursue advanced training in science and engineering in the United States pales in comparison to the numbers of science and engineering majors produced yearly in international schools. As a result, more and more jobs are being outsourced to international markets. Could international outsourcing become a method of nursing education? Authors submit that to remain competitive, the nursing profession must attract a younger cohort of technologically savvy students and faculty reflective of the growing diverse population in the United States. Additionally, nursing programs in research universities face even more daunting challenges as it relates to mandates for funded research programs of educational units. This article offers suggestions and recommendations for nursing programs in higher education institutions on ways to attract and retain ethnic minorities and of how to harness the power of research to address burgeoning societal health challenges.

2013-06-01

The aim of the study was to describe the level of burnout in midwives working at a maternity unit in South East Queensland, Australia. A self-administered questionnaire was distributed to all registered midwives (N=110) working at the study site during November 2011. The questionnaire included a demographic survey and the Copenhagen Burnout Inventory. Fifty-eight (52.7%) staff completed the package. Data was entered into SPSS database version 19 and descriptive statistics were used to determine means, ranges and frequencies. Almost 30% of the sample experienced moderate to high levels of burnout some 50% of participants scored moderate to high for personal burnout with a similar number scoring high for work-related burnout. In comparison, burnout related to working with clients was very low. Differences between participants were associated with years of experience, area of work and employment position (FT/PT, level of position and work area). Participants aged 35years or younger and with less than 10years midwifery experience scored highest on the personal and work-related domains whereas participants over 35years scored highest within the client-related domain. Midwives at level 1 (lowest pay group) scored highest for work-related burnout and client-related burnout. Midwives in more senior positions (level 2 and above) scored highest for personal burnout. Personal and work-related burnout was high in this group of midwives while burnout related to caring for women was low. These results provide insight into the emotional health of midwives in one maternity unit. While more work is needed, strategies to decrease and/or prevent burnout may include clinical mentorship and reorganising models of maternity care to increase work satisfaction and autonomy and strengthen relationships between midwives and women.

Cost-Benefit Analysis of Telemedicine Systems/Units in Greek Remote Areas.

PubMed

Kouskoukis, Marios-Nikolaos; Botsaris, Charalambos

2017-06-01

Telemedicine units and information technology systems provide special healthcare services to remote populations using telecommunication technology, in order to reduce or even remove the usual and typical face-to-face contact between doctor and patient. This innovative approach to medical care delivery has been expanding for several years and currently covers various medical specialties. To facilitate installation of telemedicine systems/units in Greek remote areas, this article presents results of a cost-benefit analysis for two Greek islands, Patmos and Leros, using specific economic criteria. Net present value (NPV), internal rate of return (IRR), and payback period were calculated, in order to monetize the economic benefits and the costs savings, estimate the depreciation of each project, and highlight the social benefits. Costs were reduced (through saved air medical transportations) by €19,005 for Patmos and €78,225 for Leros each year. NPV and IRR were positive; NPV was €29,608 for Patmos and €293,245 for Leros, and IRR was 21.5% for Patmos and 140.5% for Leros. Each project depreciated faster than the 5-year life-cycle period, and specifically in 3.13 years for Patmos and in 0.70 years for Leros. The establishment of telemedicine systems/units in Patmos and Leros was evaluated and assessed positively, with large savings, economical and social, gained by reducing or even removing the face-to-face contact between doctor and patient. Telemedicine systems/units seem to be a promising solution, especially in Greece, where the problem of primary healthcare services in remote/inaccessible areas is of great concern.

Abstract The public Finnish social and health care system has been challenged by the economic crisis, administrative reforms and increased demands. Better integration as a solution includes many examples, which have been taken to use. The most important are the rewritten national and municipals strategies and quality recommendations, where the different sectors and the levels of care are seen as one entity. Many reorganisations have taken place, both nationally and locally, and welfare clusters have been established.

Mechanisms of face perception

PubMed Central

Tsao, Doris Y.

2009-01-01

Faces are among the most informative stimuli we ever perceive: Even a split-second glimpse of a person's face tells us their identity, sex, mood, age, race, and direction of attention. The specialness of face processing is acknowledged in the artificial vision community, where contests for face recognition algorithms abound. Neurological evidence strongly implicates a dedicated machinery for face processing in the human brain, to explain the double dissociability of face and object recognition deficits. Furthermore, it has recently become clear that macaques too have specialized neural machinery for processing faces. Here we propose a unifying hypothesis, deduced from computational, neurological, fMRI, and single-unit experiments: that what makes face processing special is that it is gated by an obligatory detection process. We will clarify this idea in concrete algorithmic terms, and show how it can explain a variety of phenomena associated with face processing. PMID:18558862

Objective The purpose of this study was to evaluate the impact of the employment of additional podiatry staff on patients with diabetes attending a community-based podiatry service. Methods An audit was conducted to evaluate the intervention of two additional podiatry staff. All patients with diabetes referred to and attending community podiatry services in a specified area in the Republic of Ireland between June 2011 and June 2012 were included. The service was benchmarked against the UK gold standard outlined in the ‘Guidelines on prevention & management of foot problems in Type 2 Diabetes’ by the National Institute of Clinical Excellence (NICE). Process of care measures addressed were the number of patients with diabetes receiving treatment and the waiting times of patients with diabetes from referral to initial review. Results An increase in the number of patients with diabetes receiving treatment was seen in all risk categories (ranging from low risk to the emergency foot). Waiting times for patients with diabetes decreased post-intervention but did not reach the targets outlined in the NICE guidelines. The average time from referral to initial review of patients with an emergency diabetic foot was 37 weeks post-intervention. NICE guidelines recommend that these patients are seen within 24 hours. Discussion During the life cycle of this audit, increased numbers of patients were treated and waiting times for patients with diabetes were reduced. An internal re-organisation of the services coincided with the commencement of the additional staff. The improvements observed were due to the effects of a combination of additional staff and service re-organisation. Efficient organisation of services is key to optimal performance. Continued efforts to improve services are required to reach the standards outlined in the NICE guidelines. PMID:26048860

2014-03-01

The change of the thermohaline circulation (THC) between the Last Glacial Maximum (LGM, ≈ 21 kyr ago) and the present day climate are explored using an Ocean General Circulation Model and stream functions projected in various coordinates. Compared to the present day period, the LGM circulation is reorganised in the Atlantic Ocean, in the Southern Ocean and particularly in the abyssal ocean, mainly due to the different haline stratification. Due to stronger wind stress, the LGM tropical circulation is more vigorous than under modern conditions. Consequently, the maximum tropical transport of heat is slightly larger during the LGM. In the North Atlantic basin, the large sea-ice extent during the LGM constrains the Gulf Stream to propagate in a more zonal direction, reducing the transport of heat towards high latitudes and reorganising the freshwater transport. The LGM circulation is represented as a large intrusion of saline Antarctic Bottom Water into the Northern Hemisphere basins. As a result, the North Atlantic Deep Water is shallower in the LGM simulation. The stream functions in latitude-salinity coordinates and thermohaline coordinates point out the different haline regimes between the glacial and interglacial period, as well as a LGM Conveyor Belt circulation largely driven by enhanced salinity contrast between the Atlantic and the Pacific basin. The thermohaline structure in the LGM simulation is the result of an abyssal circulation that lifts and deviates the Conveyor Belt cell from the area of maximum volumetric distribution, resulting in a ventilated upper layer above a deep stagnant layer, and an Atlantic circulation more isolated from the Pacific. An estimation of the turnover times reveal a deep circulation almost sluggish during the LGM, and a Conveyor Belt cell more vigorous due to the combination of stronger wind stress and shortened circulation route.

Quantifying the plant actin cytoskeleton response to applied pressure using nanoindentation.

Detection of potentially pathogenic microbes through recognition by plants and animals of both physical and chemical signals associated with the pathogens is vital for host well-being. Signal perception leads to the induction of a variety of responses that augment pre-existing, constitutive defences. The plant cell wall is a highly effective preformed barrier which becomes locally reinforced at the infection site through delivery of new wall material by the actin cytoskeleton. Although mechanical stimulation can produce a reaction, there is little understanding of the nature of physical factors capable of triggering plant defence. Neither the magnitude of forces nor the contact time required has been quantified. In the study reported here, mechanical stimulation with a tungsten microneedle has been used to quantify the response of Arabidopsis plants expressing an actin-binding protein tagged with green fluorescent protein (GFP) to reveal the organisation of the actin cytoskeleton. Using confocal microscopy, the response time for actin reorganisation in epidermal cells of Arabidopsis hypocotyls was shown to be 116 ± 49 s. Using nanoindentation and a diamond spherical tip indenter, the magnitude of the forces capable of triggering an actin response has been quantified. We show that Arabidopsis hypocotyl cells can detect a force as small as 4 μN applied for as short a time as 21.6 s to trigger reorganisation of the actin cytoskeleton. This force is an order of magnitude less than the potential invasive force determined for a range of fungal and oomycete plant pathogens. To our knowledge, this is the first quantification of the magnitude and duration of mechanical forces capable of stimulating a structural defence response in a plant cell.

The myth of the 'unaffected' side after unilateral stroke: is reorganisation of the non-infarcted corticospinal system to re-establish balance the price for recovery?

2012-12-01

Bilateral changes in the hemispheric reorganisation have been observed chronically after unilateral stroke. Our hypotheses were that activity dependent competition between the lesioned and non-lesioned corticospinal systems would result in persisting asymmetry and be associated with poor recovery. Eleven subjects (medium 6.5 years after stroke) were compared to 9 age-matched controls. The power spectral density (PSD) of the sensorimotor electroencephalogram (SM1-EEG) and electromyogram (EMG) and corticomuscular coherence (CMC) were studied during rest and isometric contraction of right or left opponens pollicis (OP). Global recovery was assessed using NIH score. There was bilateral loss of beta frequency activity in the SM1-EEGs and OP-EMGs in strokes compared to controls. There was no difference between strokes and controls in symmetry indices estimated between the two corticospinal systems for SM1-EEG, OP-EMG and CMC. Performance correlated with preservation of beta frequency power in OP-EMG in both hands. Symmetry indices for the SM1-EEG, OP-EMG and CMC correlated with recovery. Significant changes occurred at both cortical and spinomuscular levels after stroke but to the same degree and in the same direction in both the lesioned and non-lesioned corticospinal systems. Global recovery correlated with the degree of symmetry between corticospinal systems at all three levels - cortical and spinomuscular levels and their connectivity (CMC), but not with the absolute degree of abnormality. Re-establishing balance between the corticospinal systems may be important for overall motor function, even if it is achieved at the expense of the non-lesioned system. Copyright © 2012 Elsevier Inc.

Target-context unitization effect on the familiarity-related FN400: a face recognition exclusion task.

PubMed

Guillaume, Fabrice; Etienne, Yann

2015-03-01

Using two exclusion tasks, the present study examined how the ERP correlates of face recognition are affected by the nature of the information to be retrieved. Intrinsic (facial expression) and extrinsic (background scene) visual information were paired with face identity and constituted the exclusion criterion at test time. Although perceptual information had to be taken into account in both situations, the FN400 old-new effect was observed only for old target faces on the expression-exclusion task, whereas it was found for both old target and old non-target faces in the background-exclusion situation. These results reveal that the FN400, which is generally interpreted as a correlate of familiarity, was modulated by the retrieval of intra-item and intrinsic face information, but not by the retrieval of extrinsic information. The observed effects on the FN400 depended on the nature of the information to be retrieved and its relationship (unitization) to the recognition target. On the other hand, the parietal old-new effect (generally described as an ERP correlate of recollection) reflected the retrieval of both types of contextual features equivalently. The current findings are discussed in relation to recent controversies about the nature of the recognition processes reflected by the ERP correlates of face recognition.

The use of moments of momentum to account for crystal habits

NASA Technical Reports Server (NTRS)

Barber, P. G.

1985-01-01

A three-step theory of crystal growth is proposed which involves first an association of molecules or ions in solution to form an impinging growth unit, then second the orientation of this unit prior to its impact on the surface of a crystal, and finally the attachment of this unit to the crystal face. From this theory the habit of a crystal is dependent upon the moments of momentum of the impinging growth unit. The results of sample calculations are presented or sodium chloride, succinic acid, sucrose, and chromium boride. The faces predicted by this proposed theory are compared with those predicted by other, energy-based calculations and with those experimentally observed. The proposed theory suggests alternative strategies for crystallization and habit modification which may be of technological importance. Listings of the two computer programs that were used are provided.

Accurate visible speech synthesis based on concatenating variable length motion capture data.

2006-01-01

We present a novel approach to synthesizing accurate visible speech based on searching and concatenating optimal variable-length units in a large corpus of motion capture data. Based on a set of visual prototypes selected on a source face and a corresponding set designated for a target face, we propose a machine learning technique to automatically map the facial motions observed on the source face to the target face. In order to model the long distance coarticulation effects in visible speech, a large-scale corpus that covers the most common syllables in English was collected, annotated and analyzed. For any input text, a search algorithm to locate the optimal sequences of concatenated units for synthesis is desrcribed. A new algorithm to adapt lip motions from a generic 3D face model to a specific 3D face model is also proposed. A complete, end-to-end visible speech animation system is implemented based on the approach. This system is currently used in more than 60 kindergarten through third grade classrooms to teach students to read using a lifelike conversational animated agent. To evaluate the quality of the visible speech produced by the animation system, both subjective evaluation and objective evaluation are conducted. The evaluation results show that the proposed approach is accurate and powerful for visible speech synthesis.

Non-intrusive head movement analysis of videotaped seizures of epileptic origin.

2012-01-01

In this work we propose a non-intrusive video analytic system for patient's body parts movement analysis in Epilepsy Monitoring Unit. The system utilizes skin color modeling, head/face pose template matching and face detection to analyze and quantify the head movements. Epileptic patients' heads are analyzed holistically to infer seizure and normal random movements. The patient does not require to wear any special clothing, markers or sensors, hence it is totally non-intrusive. The user initializes the person-specific skin color and selects few face/head poses in the initial few frames. The system then tracks the head/face and extracts spatio-temporal features. Support vector machines are then used on these features to classify seizure-like movements from normal random movements. Experiments are performed on numerous long hour video sequences captured in an Epilepsy Monitoring Unit at a local hospital. The results demonstrate the feasibility of the proposed system in pediatric epilepsy monitoring and seizure detection.

This study reports early evidence from the development of clinical commissioning groups (CCGs), a key element in the new structures. To explore the development of CCGs in the context of what is known from previous studies of GP involvement in commissioning. Case study analysis from sites chosen to provide maximum variety across a number of dimensions, from September 2011 to June 2012. A case study analysis was conducted using eight detailed qualitative case studies supplemented by descriptive information from web surveys at two points in time. Data collection involved observation of a variety of meetings, and interviews with key participants. Previous research shows that clinical involvement in commissioning is most effective when GPs feel able to act autonomously. Complicated internal structures, alongside developing external accountability relationships mean that CCGs' freedom to act may be subject to considerable constraint. Effective GP engagement is also important in determining outcomes of clinical commissioning, and there are a number of outstanding issues for CCGs, including: who feels 'ownership' of the CCG; how internal communication is conceptualised and realised; and the role and remit of locality groups. Previous incarnations of GP-led commissioning have tended to focus on local and primary care services. CCGs are keen to act to improve quality in their constituent practices, using approaches that many developed under practice-based commissioning. Constrained managerial support and the need to maintain GP engagement may have an impact. CCGs are new organisations, faced with significant new responsibilities. This study provides early evidence of issues that CCGs and those responsible for CCG development may wish to address.

The National Health Service (NHS) at 70: Bevan's double-edged legacy.

Klein, Rudolf

2018-01-08

The paper analyses the achievements and problems stemming from Nye Bevan's model of a tax funded national health care system, on the assumption that only so could equity be achieved. The evidence shows that indeed the National Health Service (NHS) scores highly on equity, so vindicating Bevan's vision. The price paid is that fiscal crises are the norm for the NHS, with ever more centralisation, intensive regulation and performance management. Successive reorganisations represent attempts to square the circle - to combine the strengths of Bevan's model and those of a less hierarchic system - but have so far failed to deliver and can be expected to continue.

Several visual areas within the STS of the macaque brain respond strongly to faces and other biological stimuli. Determining the principles that govern neural responses in this region has proven challenging, due in part to the inherently complex stimulus domain of dynamic biological stimuli that are not captured by an easily parameterized stimulus set. Here we investigated neural responses in one fMRI-defined face patch in the anterior fundus (AF) of the STS while macaques freely view complex videos rich with natural social content. Longitudinal single-unit recordings allowed for the accumulation of each neuron's responses to repeated video presentations across sessions. We found that individual neurons, while diverse in their response patterns, were consistently and deterministically driven by the video content. We used principal component analysis to compute a family of eigenneurons, which summarized 24% of the shared population activity in the first two components. We found that the most prominent component of AF activity reflected an interaction between visible body region and scene layout. Close-up shots of faces elicited the strongest neural responses, whereas far away shots of faces or close-up shots of hindquarters elicited weak or inhibitory responses. Sensitivity to the apparent proximity of faces was also observed in gamma band local field potential. This category-selective sensitivity to spatial scale, together with the known exchange of anatomical projections of this area with regions involved in visuospatial analysis, suggests that the AF face patch may be specialized in aspects of face perception that pertain to the layout of a social scene.

Human DNA is the main unit that shapes human characteristics and features such as behavior. Thus, it is expected that changes in DNA (DNA mutation) influence human characteristics and features. Face is one of the human features which is unique and also dependent on his gen. In this paper, for the first time we analyze the variations of human DNA and face simultaneously. We do this job by analyzing the fractal dimension of DNA walk and face during human aging. The results of this study show the human DNA and face get more complex by aging. These complexities are mapped on fractal exponents of DNA walk and human face. The method discussed in this paper can be further developed in order to investigate the direct influence of DNA mutation on the face variations during aging, and accordingly making a model between human face fractality and the complexity of DNA walk.

Sound absorption of a porous material with a perforated facing at high sound pressure levels

NASA Astrophysics Data System (ADS)

Peng, Feng

2018-07-01

A semi-empirical model is proposed to predict the sound absorption of an acoustical unit consisting of a rigid-porous material layer with a perforated facing under the normal incidence at high sound pressure levels (SPLs) of pure tones. The nonlinearity of the perforated facing and the porous material, and the interference between them are considered in the model. The sound absorptive performance of the acoustical unit is tested at different incident SPLs and in three typical configurations: 1) when the perforated panel (PP) directly contacts with the porous layer, 2) when the PP is separated from the porous layer by an air gap and 3) when an air cavity is set between the porous material and the hard backing wall. The test results agree well with the corresponding theoretical predictions. Moreover, the results show that the interference effect is correlated to the width of the air gap between the PP and the porous layer, which alters not only the linear acoustic impedance but also the nonlinear acoustic impedance of the unit and hence its sound absorptive properties.

Self- or familiar-face recognition advantage? New insight using ambient images.

PubMed

Bortolon, Catherine; Lorieux, Siméon; Raffard, Stéphane

2018-06-01

Self-face recognition has been widely explored in the past few years. Nevertheless, the current literature relies on the use of standardized photographs which do not represent daily-life face recognition. Therefore, we aim for the first time to evaluate self-face processing in healthy individuals using natural/ambient images which contain variations in the environment and in the face itself. In total, 40 undergraduate and graduate students performed a forced delayed-matching task, including images of one's own face, friend, famous and unknown individuals. For both reaction time and accuracy, results showed that participants were faster and more accurate when matching different images of their own face compared to both famous and unfamiliar faces. Nevertheless, no significant differences were found between self-face and friend-face and between friend-face and famous-face. They were also faster and more accurate when matching friend and famous faces compared to unfamiliar faces. Our results suggest that faster and more accurate responses to self-face might be better explained by a familiarity effect - that is, (1) the result of frequent exposition to one's own image through mirror and photos, (2) a more robust mental representation of one's own face and (3) strong face recognition units as for other familiar faces.

Framing faces: Frame alignment impacts holistic face perception.

PubMed

Curby, Kim M; Entenman, Robert

2016-11-01

Traditional accounts of face perception emphasise the importance of the prototypical configuration of features within faces. However, here we probe influences of more general perceptual grouping mechanisms on holistic face perception. Participants made part-matching judgments about composite faces presented in intact external oval frames or frames made from misaligned oval parts. This manipulation served to disrupt basic perceptual grouping cues that facilitate the grouping of the two face halves together. This manipulation also produced an external face contour like that in the standard misaligned condition used within the classic composite face task. Notably, by introducing a discontinuity in the external contour, grouping of the face halves into a cohesive unit was discouraged, but face configuration was preserved. Conditions where both the face parts and the frames were misaligned together, as in the typical composite task paradigm, or where just the internal face parts where misaligned, were also included. Disrupting only the face frame similarly disrupted holistic face perception as disrupting both the frame and face configuration. However, misaligned face parts presented in aligned frames also incurred a cost to holistic perception. These findings provide support for the contribution of general-purpose perceptual grouping mechanisms to holistic face perception and are presented and discussed in the context of an enhanced object-based selection account of holistic perception.

Aiming at heat injuries occurring in the process of deep coal mining in China, a ZL400 mine-cooling unit employing semi-hermetic screw compressor with a cooling capacity of 400 kW is developed. This paper introduced its operating principle, structural characteristics and technical indexes. By using the self-built testing platform, some parameters for indication of its operation conditions were tested on the ground. The results show that the aforementioned cooling unit is stable in operation: cooling capacity of the unit was 420 kW underground-test conditions, while its COP (coefficient of performance) reached 3.4. To address the issue of heat injuries existing in No. 16305 U-shaped long-wall ventilation face of Jining No. 3 coal mine, a local air conditioning system was developed with ZL400 cooling unit as the system's core. The paper presented an analysis of characteristics of the air current flowing in the air-mixing and cooling mode of ZL400 cooling unit used in air intake way. Through i-d patterns we described the process of the airflow treatment, such as cooling, mixing and heating, etc. The cooling system decreased dry bulb temperature on working face by 3°C on average and 3.8°C at most, while lowered the web bulb temperature by 3.6°C on average and 4.8°C at most. At the same time, it reduced relative humidity by 5% on average and 8.6% at most. The field application of the ZL400 cooling unit had gain certain effects in air conditioning and provided support for the solution of mine heat injuries in China in terms of technology and equipment.

In 2005, approximately 400,000 people provided primary medical care in the United States. About 300,000 were physicians, and another 100,000 were nurse practitioners and physician assistants. Yet primary care faces a growing crisis, in part because increasing numbers of U.S. medical graduates are avoiding careers in adult primary care. Sixty-five million Americans live in what are officially deemed primary care shortage areas, and adults throughout the United States face difficulty obtaining prompt access to primary care. A variety of strategies are being tried to improve primary care access, even without a large increase in the primary care workforce.

Less is more? Detecting lies in veiled witnesses.

2016-08-01

Judges in the United States, the United Kingdom, and Canada have ruled that witnesses may not wear the niqab-a type of face veil-when testifying, in part because they believed that it was necessary to see a person's face to detect deception (Muhammad v. Enterprise Rent-A-Car, 2006; R. v. N. S., 2010; The Queen v. D(R), 2013). In two studies, we used conventional research methods and safeguards to empirically examine the assumption that niqabs interfere with lie detection. Female witnesses were randomly assigned to lie or tell the truth while remaining unveiled or while wearing a hijab (i.e., a head veil) or a niqab (i.e., a face veil). In Study 1, laypersons in Canada (N = 232) were more accurate at detecting deception in witnesses who wore niqabs or hijabs than in those who did not wear veils. Concealing portions of witnesses' faces led laypersons to change their decision-making strategies without eliciting negative biases. Lie detection results were partially replicated in Study 2, with laypersons in Canada, the United Kingdom, and the Netherlands (N = 291): observers' performance was better when witnesses wore either niqabs or hijabs than when witnesses did not wear veils. These findings suggest that, contrary to judicial opinion, niqabs do not interfere with-and may, in fact, improve-the ability to detect deception.

A Review of Factors Influencing the Banking of Collected Umbilical Cord Blood Units

2013-01-01

Umbilical cord blood banking efforts have increased dramatically in the past two decades in response to increasing demand for alternative sources of blood stem cells to support patients requiring hematopoietic stem cell transplantation. Transplant centres have accumulated increasing expertise in their understanding of umbilical cord blood characteristics that are associated with improved outcome following transplantation. These characteristics and factors can assist transplant centres in selecting cord blood units from the worldwide inventory of banked units. Umbilical cord blood banks, therefore, need to remain agile in adjusting the inventory of the banks to address shifts or changes in the needs of transplant centres. Public umbilical cord blood banks face the challenge of building inventory while managing limited resources and are faced with decisions regarding which units can be stored and which units that have been collected should be discarded or used for other endeavours such as research. To this end, we sought to review parameters influencing the decision to bank a collected cord blood unit. In this paper, we will address parameters associated with graft potency and address other factors that guide the decision to bank collected units. PMID:23533442

Interviewer characteristics affect nonresponse and measurement errors in face-to-face surveys. Some studies have shown that mismatched sociodemographic characteristics - for example gender - affect people's behavior when interacting with an interviewer at the door and during the survey interview, resulting in more nonresponse. We investigate the effect of sociodemographic (mis)matching on nonresponse in two successive rounds of the European Social Survey in Belgium. As such, we replicate the analyses of the effect of (mis)matching gender and age on unit nonresponse on the one hand, and of gender, age and education level (mis)matching on item nonresponse on the other hand. Recurring effects of sociodemographic (mis)match are found for both unit and item nonresponse. Copyright © 2017 Elsevier Inc. All rights reserved.

Standardized handoffs may reduce communication errors, but research on handoff in community and international settings is lacking. Our study at a community hospital in the United Arab Emirates characterizes existing handoff practices for admitted patients from emergency medicine (EM) to internal medicine (IM), develops a standardized handoff tool, and assesses its impact on communication and physician perceptions. EM physicians completed a survey regarding handoff practices and expectations. Trained observers utilized a checklist based on the Systems Engineering Initiative for Patient Safety model to observe 40 handoffs. EM and IM physicians collaboratively developed a written tool encouraging bedside handoff of admitted patients. After the intervention, surveys of EM physicians and 40 observations were subsequently repeated. 77.5% of initial observed handoffs occurred face-to-face, with 42.5% at bedside, and in four different languages. Most survey respondents considered face-to-face handoff ideal. Respondents noted 9-13 patients suffering harm due to handoff in the prior month. After handoff tool implementation, 97.5% of observed handoffs occurred face-to-face (versus 77.5%, p = 0.014), with 82.5% at bedside (versus 42.5%, p < 0.001), and all in English. Handoff was streamlined from 7 possible pathways to 3. Most post-intervention survey respondents reported improved workflow (77.8%) and safety (83.3%); none reported patient harm. Respondents and observers noted reduced inefficiency (p < 0.05). Our standardized tool increased face-to-face and bedside handoff, positively impacted workflow, and increased perceptions of safety by EM physicians in an international, non-academic setting. Our three-step approach can be applied towards developing standardized, context-specific inter-specialty handoff in a variety of settings.

Mapping the emotional face. How individual face parts contribute to successful emotion recognition.

Which facial features allow human observers to successfully recognize expressions of emotion? While the eyes and mouth have been frequently shown to be of high importance, research on facial action units has made more precise predictions about the areas involved in displaying each emotion. The present research investigated on a fine-grained level, which physical features are most relied on when decoding facial expressions. In the experiment, individual faces expressing the basic emotions according to Ekman were hidden behind a mask of 48 tiles, which was sequentially uncovered. Participants were instructed to stop the sequence as soon as they recognized the facial expression and assign it the correct label. For each part of the face, its contribution to successful recognition was computed, allowing to visualize the importance of different face areas for each expression. Overall, observers were mostly relying on the eye and mouth regions when successfully recognizing an emotion. Furthermore, the difference in the importance of eyes and mouth allowed to group the expressions in a continuous space, ranging from sadness and fear (reliance on the eyes) to disgust and happiness (mouth). The face parts with highest diagnostic value for expression identification were typically located in areas corresponding to action units from the facial action coding system. A similarity analysis of the usefulness of different face parts for expression recognition demonstrated that faces cluster according to the emotion they express, rather than by low-level physical features. Also, expressions relying more on the eyes or mouth region were in close proximity in the constructed similarity space. These analyses help to better understand how human observers process expressions of emotion, by delineating the mapping from facial features to psychological representation.

2003-03-03

The purpose of this study was to disentangle the contribution of episodic-perceptual from pre-existing memory representations of faces to repetition effects. ERPs were recorded to first and second presentations of same and different photos of famous and unfamiliar faces, in an incidental task where occasional non-targets had to be detected. Repetition of same and different photos of famous faces resulted in an N400 amplitude decrement. No such N400 repetition-induced attenuation was observed for unfamiliar faces. In addition, repetition of same photos of faces, and not different ones, gave rise to an early ERP repetition effect (starting at approximately 350 ms) with an occipito-temporal scalp distribution. Together, these results suggest that repetition effects depend on two temporally and may be neuro-functionally distinct loci, episode-based representation and face recognition units stored in long-term memory.

Global shape information increases but color information decreases the composite face effect.

PubMed

Retter, Talia L; Rossion, Bruno

2015-01-01

The separation of visual shape and surface information may be useful for understanding holistic face perception--that is, the perception of a face as a single unit (Jiang, Blanz, & Rossion, 2011, Visual Cognition, 19, 1003-1034). A widely used measure of holistic face perception is the composite face effect (CFE), in which identical top face halves appear different when aligned with bottom face halves from different identities. In the present study the influences of global face shape (ie contour of the face) and color information on the CFE are investigated, with the hypothesis that global face shape supports but color impairs holistic face perception as measured in this paradigm. In experiment 1 the CFE is significantly increased when face stimuli possess natural global shape information than when cropped to a generic (ie oval) global shape; this effect is not found when the stimuli are presented inverted. In experiment 2 the CFE is significantly decreased when face stimuli are presented with color information than when presented in grayscale. These findings indicate that grayscale stimuli maintaining natural global face shape information provide the most adept measure of holistic face perception in the behavioral composite face paradigm. More generally, they show that reducing different types of information diagnostic for individual face perception can have opposite effects on the CFE, illustrating the functional dissociation between shape and surface information in face perception.

Decision conflict and regret among surrogate decision makers in the medical intensive care unit.

2016-04-01

Family members of critically ill patients in the intensive care unit face significant morbidity. It may be the decision-making process that plays a significant role in the psychological morbidity associated with being a surrogate in the ICU. We hypothesize that family members facing end-of-life decisions will have more decisional conflict and decisional regret than those facing non-end-of-life decisions. We enrolled a sample of adult patients and their surrogates in a tertiary care, academic medical intensive care unit. We queried the surrogates regarding decisions they had made on behalf of the patient and assessed decision conflict. We then contacted the family member again to assess decision regret. Forty (95%) of 42 surrogates were able to identify at least 1 decision they had made on behalf of the patient. End-of-life decisions (defined as do not resuscitate [DNR]/do not intubate [DNI] or continuation of life support) accounted for 19 of 40 decisions (47.5%). Overall, the average Decision Conflict Scale (DCS) score was 21.9 of 100 (range 0-100, with 0 being little decisional conflict and 100 being great decisional conflict). The average DCS score for families facing end-of-life decisions was 25.5 compared with 18.7 for all other decisions. Those facing end-of-life decisions scored higher on the uncertainty subscale (subset of DCS questions that indicates level of certainty regarding decision) with a mean score of 43.4 compared with all other decisions with a mean score of 27.0. Overall, very few surrogates experienced decisional regret with an average DRS score of 13.4 of 100. Nearly all surrogates enrolled were faced with decision-making responsibilities on behalf of his or her critically ill family member. In our small pilot study, we found more decisional conflict in those surrogates facing end-of-life decisions, specifically on the subset of questions dealing with uncertainty. Surrogates report low levels of decisional regret. Copyright © 2015 Elsevier Inc. All rights reserved.

The primate amygdala in social perception - insights from electrophysiological recordings and stimulation

PubMed Central

Rutishauser, Ueli; Mamelak, Adam N.; Adolphs, Ralph

2015-01-01

The amygdala’s role in emotion and social perception has been intensively investigated primarily through studies using fMRI. Recently, this topic has been examined using single-unit recordings in both humans and monkeys, with a focus on face processing. The findings provide novel insights, including several surprises: amygdala neurons have very long response latencies, show highly nonlinear responses to whole faces, and can be exquisitely selective for very specific parts of faces such as the eyes. In humans, the responses of amygdala neurons correlate with internal states evoked by faces, rather than with their objective features. Current and future studies extend the investigations to psychiatric illnesses such as autism, in which atypical face processing is a hallmark of social dysfunction. PMID:25847686

The influence of nationality on the accuracy of face and voice recognition.

PubMed

Doty, N D

1998-01-01

Sixty English and U.S. citizens were tested to determine the effect of nationality on accuracy in recognizing previously witnessed faces and voices. Subjects viewed a frontal facial photograph and were then asked to select that face from a set of 10 oblique facial photographs. Subjects listened to a recorded voice and were then asked to select the same voice from a set of 10 voice recordings. This process was repeated 7 more times, such that subjects identified a male and female face and voice from England, France, Belize, and the United States. Subjects demonstrated better accuracy recognizing the faces and voices of their own nationality.

Kröger, Bernd J; Kopp, Stefan; Lowit, Anja

2010-08-01

The concept of action as basic motor control unit for goal-directed movement behavior has been used primarily for private or non-communicative actions like walking, reaching, or grasping. In this paper, literature is reviewed indicating that this concept can also be used in all domains of face-to-face communication like speech, co-verbal facial expression, and co-verbal gesturing. Three domain-specific types of actions, i.e. speech actions, facial actions, and hand-arm actions, are defined in this paper and a model is proposed that elucidates the underlying biological mechanisms of action production, action perception, and action acquisition in all domains of face-to-face communication. This model can be used as theoretical framework for empirical analysis or simulation with embodied conversational agents, and thus for advanced human-computer interaction technologies.

Intravenous thrombolysis with alteplase is an effective treatment for ischaemic stroke when applied during the first 4.5 hours, but less than 15% of patients have access to this technique. Mechanical thrombectomy is more frequently able to recanalise proximal occlusions in large vessels, but the infrastructure it requires makes it even less available. We describe the implementation of code stroke in Asturias, as well as the process of adapting various existing resources for urgent stroke care in the region. By considering these resources, and the demographic and geographic circumstances of our region, we examine ways of reorganising the code stroke protocol that would optimise treatment times and provide the most appropriate treatment for each patient. We distributed the 8 health districts in Asturias so as to permit referral of candidates for reperfusion therapies to either of the 2 hospitals with 24-hour stroke units and on-call neurologists and providing IV fibrinolysis. Hospitals were assigned according to proximity and stroke severity; the most severe cases were immediately referred to the hospital with on-call interventional neurology care. Patient triage was provided by pre-hospital emergency services according to the NIHSS score. Modifications to code stroke in Asturias have allowed us to apply reperfusion therapies with good results, while emphasising equitable care and managing the severity-time ratio to offer the best and safest treatment for each patient as soon as possible.

2017-11-01

To examine the nurse manager perspective surrounding implementation of unit level shared governance in one Veterans Health Administration facility. Nursing shared governance is a formal model allowing nursing staff decision-making input into clinical practice, quality improvement, evidence-based practice and staff professional development. Unit level shared governance is a management process where decision authority is delegated to nursing staff at the unit level. Convenience sampling was used to recruit ten nurse managers who participated in face-to-face semi-structured interviews. Data were analysed using content analysis and constant comparison techniques. Demographic data were described using descriptive statistics. The participants included seven female and three male nurse managers with seven Caucasian and three African American. Participant quotes were clustered to identify sub-themes that were then grouped into four global themes to describe unit level shared governance. The global themes were: (1) motivation, (2) demotivation, (3) recommendations for success, and (4) outcomes. These research findings resonate with previous studies that shared governance may be associated with increased nurse empowerment, self-management, engagement, and satisfaction. These findings reflect the need for nurse managers to promote and recognize staff participation in unit level shared governance. © 2017 John Wiley & Sons Ltd.

Along the United States–Mexican border, the health of communities, economies, and ecosystems is inextricably intertwined with the availability and quality of water, but effective water management in the Borderlands is complicated. Water users compete for resources, and their needs are increasing. Managers are faced with issues such as finding a balance between agriculture and rapidly growing cities or maintaining public supplies while ensuring sufficient resources for aquatic ecosystems. In addition to human factors, the dry climate of the Borderlands, as compared to more temperate regions, also increases the challenge of balancing water supplies between humans and ecosystems. Warmer, drier, and more variable conditions across the southwestern United States—the projected results of climate change (Seager and others, 2007)—would further stress water supplies.

To identify actions to reduce medication errors in the process of drug prescription, validation and dispensing, and to evaluate the impact of their implementation. A Health Care Failure Mode and Effect Analysis (HFMEA) was supported by a before-and-after medication error study to measure the actual impact on error rate after the implementation of corrective actions in the process of drug prescription, validation and dispensing in wards equipped with computerised physician order entry (CPOE) and unit-dose distribution system (788 beds out of 1080) in a Spanish university hospital. The error study was carried out by two observers who reviewed medication orders on a daily basis to register prescription errors by physicians and validation errors by pharmacists. Drugs dispensed in the unit-dose trolleys were reviewed for dispensing errors. Error rates were expressed as the number of errors for each process divided by the total opportunities for error in that process times 100. A reduction in prescription errors was achieved by providing training for prescribers on CPOE, updating prescription procedures, improving clinical decision support and automating the software connection to the hospital census (relative risk reduction (RRR), 22.0%; 95% CI 12.1% to 31.8%). Validation errors were reduced after optimising time spent in educating pharmacy residents on patient safety, developing standardised validation procedures and improving aspects of the software's database (RRR, 19.4%; 95% CI 2.3% to 36.5%). Two actions reduced dispensing errors: reorganising the process of filling trolleys and drawing up a protocol for drug pharmacy checking before delivery (RRR, 38.5%; 95% CI 14.1% to 62.9%). HFMEA facilitated the identification of actions aimed at reducing medication errors in a healthcare setting, as the implementation of several of these led to a reduction in errors in the process of drug prescription, validation and dispensing.

Hemispheric asymmetry in holistic processing of words.

Holistic processing has been regarded as a hallmark of face perception, indicating the automatic and obligatory tendency of the visual system to process all face parts as a perceptual unit rather than in isolation. Studies involving lateralized stimulus presentation suggest that the right hemisphere dominates holistic face processing. Holistic processing can also be shown with other categories such as words and thus it is not specific to faces or face-like expertize. Here, we used divided visual field presentation to investigate the possibly different contributions of the two hemispheres for holistic word processing. Observers performed same/different judgment on the cued parts of two sequentially presented words in the complete composite paradigm. Our data indicate a right hemisphere specialization for holistic word processing. Thus, these markers of expert object recognition are domain general.

Genetic specificity of face recognition.

PubMed

Shakeshaft, Nicholas G; Plomin, Robert

2015-10-13

Specific cognitive abilities in diverse domains are typically found to be highly heritable and substantially correlated with general cognitive ability (g), both phenotypically and genetically. Recent twin studies have found the ability to memorize and recognize faces to be an exception, being similarly heritable but phenotypically substantially uncorrelated both with g and with general object recognition. However, the genetic relationships between face recognition and other abilities (the extent to which they share a common genetic etiology) cannot be determined from phenotypic associations. In this, to our knowledge, first study of the genetic associations between face recognition and other domains, 2,000 18- and 19-year-old United Kingdom twins completed tests assessing their face recognition, object recognition, and general cognitive abilities. Results confirmed the substantial heritability of face recognition (61%), and multivariate genetic analyses found that most of this genetic influence is unique and not shared with other cognitive abilities.

Changes in singing performance and fMRI activation following right temporal lobe surgery.

Wilson, Sarah J; Abbott, David F; Tailby, Chris; Gentle, Ellen C; Merrett, Dawn L; Jackson, Graeme D

2013-10-01

This study arose in the context of having to estimate risk to the musical abilities of a trained singer (patient A.M.) recommended for right anterior temporal lobectomy (RATL) to ameliorate medically intractable seizures. To date there has been no systematic investigation of reorganisation of musical functions in the presence of epileptogenic lesions, although it is well established that RATL can impair pitch processing in nonmusicians. Using fMRI, we compared the network activated by covert singing with lyrics in A.M. before and after surgery, while taking language activation and singing expertise into consideration. Before surgery, A.M. showed lower pitch accuracy of singing relative to individuals of similar experience (experts), thus we compared her to 12 healthy controls matched for singing pitch accuracy. We found atypical organisation of A.M.'s singing network before surgery in the presence of a malformation of cortical development, including partial activation of the singing network of pitch-matched controls, and diffuse activation along the midline spreading laterally into association cortex, typical of generalised cortical hyperexcitability in intractable epilepsy. After tailored RATL, A.M. showed striking behavioural and neuroimaging changes, including significant improvement in pitch accuracy of singing relative to controls (p = .026) and the subjective experience of being a more technically proficient singer. This was accompanied by a significant reduction in cortical activation (p < .05, corrected), with a more focal, expert-like pattern of singing activation emerging, including decreased involvement of frontal language regions. These changes were largely specific to singing, with A.M. showing language activation and performance similar to controls. This case provides evidence for selective disruption of the singing network that reorganised after successful resection of an epileptogenic lesion and likely occurred through decoupling of the singing and language networks.

Home care services for sick children: Healthcare professionals' conceptions of challenges and facilitators.

2017-09-01

To explore healthcare professionals' conceptions of caring for sick children in home care services. Families often prefer home care to hospital care, and the number of home care services for children is increasing. Caring for children at home has been recognised as challenging for healthcare professionals in home care services used to providing care predominately for adults. An inductive qualitative design. Seven focus group interviews were performed with 36 healthcare professionals from multidisciplinary home care services. Data were analysed stepwise using a phenomenographic analysis. Three description categories emerged: "A challenging opportunity", "A child perspective", and "Re-organise in accordance with new prerequisites." Providing home care services for children was conceived to evoke both professional and personal challenges such as feelings of inadequacy and fear and professional growth such as increased competence and satisfaction. Conceptions of whether the home or the hospital was the best place for care differed. Adapting to the child's care was conceived as important. Cooperation with paediatric departments and a well-functioning team work were important organisational aspects. Providing home care for children was a challenging but rewarding task for healthcare professionals used to care for adults. To provide care with a child perspective was experienced as important even though there were conflicting conceptions of how this should be done. Close cooperation with paediatric departments and teamwork were prerequisites that make up for the low number of paediatric patients and facilitate confidence and competence. A sufficient number of referred children and enabling healthcare professionals to be part of the re-organising and implementation processes might facilitate the home care services for sick children. Enough time and good teamwork must be emphasised. Early referrals, continuous cooperation with paediatric clinics complemented with individualised support when a child is referred is desirable. © 2017 The Authors.

A paradigm shift in management of postburn facial scarring is lurking "just beneath the waves" with the widespread availability of two recent technologies: precise three-dimensional scanning/digitizing of complex surfaces and computer-controlled rapid prototyping three-dimensional "printers". Laser Doppler imaging may be the sensible method to track the scar hyperemia that should form the basis of assessing progress and directing incremental changes in the digitized topographical face mask "prescription". The purpose of this study was to establish feasibility of detecting perfusion through transparent face masks using the Laser Doppler Imaging scanner. Laser Doppler images of perfusion were obtained at multiple facial regions on five uninjured staff members. Images were obtained without a mask, followed by images with a loose fitting mask with and without a silicone liner, and then with a tight fitting mask with and without a silicone liner. Right and left oblique images, in addition to the frontal images, were used to overcome unobtainable measurements at the extremes of face mask curvature. General linear model, mixed model, and t tests were used for data analysis. Three hundred seventy-five measurements were used for analysis, with a mean perfusion unit of 299 and pixel validity of 97%. The effect of face mask pressure with and without the silicone liner was readily quantified with significant changes in mean cutaneous blood flow (P < .5). High valid pixel rate laser Doppler imager flow data can be obtained through transparent face masks. Perfusion decreases with the application of pressure and with silicone. Every participant measured differently in perfusion units; however, consistent perfusion patterns in the face were observed.

Severe complex facial injuries are difficult to reconstruct and require multiple surgical procedures. The potential of performing complex craniofacial reconstruction in one surgical procedure is appealing, and composite face allograft transplantation may be considered an alternative option. The authors describe establishment of the Cleveland Clinic face transplantation program that led them to perform the first U.S. near-total face transplantation. In November of 2004, the authors received the world's first institutional review board approval to perform a face transplant in humans. In December of 2008, after a 22-hour operation, the authors performed the first near-total face transplantation in the United States, replacing 80 percent of the patient's traumatic facial deficit with a composite allograft from a brain-dead donor. This largest, and most complex, face allograft in the world included over 535 cm2 of facial skin; functional units of full nose with nasal lining and bony skeleton; lower eyelids and upper lip; underlying muscles and bones, including orbital floor, zygoma, maxilla, alveolus with teeth, hard palate, and parotid glands; and pertinent nerves, arteries, and veins. Immunosuppressive treatment consisted of thymoglobulin, tacrolimus, mycophenolate mofetil, and prednisone. The patient tolerated the procedure and immunosuppression well. At day 47 after transplantation, routine biopsy showed rejection of the graft mucosa without clinical evidence of skin or graft rejection. The patient's physical and psychological recovery went well. The functional outcome has been excellent, including optimal return of breathing through the nose, smelling, tasting, speaking, drinking from a cup, and eating solid foods. The functional outcome thus far at 8 months is rewarding and confirms the feasibility of performing complex reconstruction of severely disfigured patients in a single surgical procedure of facial allotransplantation.

A porphyrin-ferrocene dyad has been synthesized in which there is close face-to-face contact between the two aromatic systems, providing a model for heterobimetallic polymers based on the same repeating unit. Attempts to synthesize the 2:1 adduct instead led to a remarkable intramolecular Heck-type cyclization which planarizes the system and extends the conjugation. [structure: see text

Reading faces: investigating the use of a novel face-based orthography in acquired alexia.

PubMed

Moore, Michelle W; Brendel, Paul C; Fiez, Julie A

2014-02-01

Skilled visual word recognition is thought to rely upon a particular region within the left fusiform gyrus, the visual word form area (VWFA). We investigated whether an individual (AA1) with pure alexia resulting from acquired damage to the VWFA territory could learn an alphabetic "FaceFont" orthography, in which faces rather than typical letter-like units are used to represent phonemes. FaceFont was designed to distinguish between perceptual versus phonological influences on the VWFA. AA1 was unable to learn more than five face-phoneme mappings, performing well below that of controls. AA1 succeeded, however, in learning and using a proto-syllabary comprising 15 face-syllable mappings. These results suggest that the VWFA provides a "linguistic bridge" into left hemisphere speech and language regions, irrespective of the perceptual characteristics of a written language. They also suggest that some individuals may be able to acquire a non-alphabetic writing system more readily than an alphabetic writing system. Copyright © 2013 Elsevier Inc. All rights reserved.

Intersectionality at Work: South Asian Muslim Women's Experiences of Employment and Leadership in the United Kingdom.

PubMed

Tariq, Memoona; Syed, Jawad

2017-01-01

Drawing on qualitative interviews with 20 South Asian heritage, Muslim, female leaders, managers, and supervisors in the United Kingdom, we examine the multi-layered issues and challenges they face in pursuit of employment and leadership positions. The paper offers an intersectional perspective taking into account interconnected and overlapping factors (gender, ethnicity, religion, and family status) that affect not only the issues and challenges these women face in the labour market but also the individual agency and strategies they use to overcome any obstacles in the way of their employment and career. The results show that although Muslim women continue to face a myriad of challenges in the workplace, they are also able to tackle some of these issues through their individual strategies and networks, such as personal networks and further education. The study highlights the need for policymakers and employers to consider intersectionality to enable ethnic minority women's inclusion and leadership within and outside the workplace.

Geostatistical analysis of ground-penetrating radar data: A means of describing spatial variation in the subsurface

NASA Astrophysics Data System (ADS)

Rea, Jane; Knight, Rosemary

1998-03-01

We have investigated the use of ground-penetrating radar (GFR) as a means of characterizing the heterogeneity of the subsurface. Radar data were collected at several sites in southwestern British Columbia underlain by glaciodeltaic sediments. A cliff face study was conducted in which geostatistical analysis of a digitized photograph of the face and the radar image of the face showed excellent agreement in the maximum correlation direction and the correlation length determined from these two data sets. Other two-dimensional (2-D) sections of radar data were divided into sedimentary architectural elements on the basis of the distinct radar appearance of these sedimentary units. Examples of four sedimentary units were used to obtain semivariograms from the radar data and resulted in maximum correlation lengths between 0.5 and 4.8 m. A 3-D radar survey, collected over a package of gravel and sand foresets, was analyzed to determine the paleoflow direction; a correlation length of 4 m was found in that direction.

To describe the content of former intensive care unit patients' memories of delusions. Intensive care unit patients often have strange and frightening experiences during the critical stage of illness. Earlier studies have provided small-sample in-depth descriptions of patient experiences in intensive care unit, but large-scale studies are also needed to inform intensive care unit follow-up. The study had a qualitative design using phenomenological hermeneutic analysis inspired by Ricoeur's interpretive theory. Patients were assessed with Confusion Assessment Method of the Intensive Care Unit for delirium in intensive care unit, and after discharge, memories of delusions were described by 114 of 325 patients in face-to-face (after two weeks) and telephone interviews (after two and six months) using the Intensive Care Unit Memory Tool. Four themes emerged: the ever-present family, dynamic spaces, surviving challenges and constant motion. Memories of delusions were a vivid mix of fact and fiction, demonstrating dynamic shifts in time, place and motion, but not dependent on the presence of delirium assessed by Confusion Assessment Method of the Intensive Care Unit. Analysis based on Ricoeurian phenomenological hermeneutics provided insights into themes in intensive care unit patients' memories of delusions. More studies are needed to understand the meaning of memories of delusions, the commonality of themes and the association between delusions and delirium after an intensive care unit stay. Understanding patients' memories of delusions is beneficial to nurses caring for patients that are anxious, upset or agitated. It opens a window to the world of the patient who is unable to communicate due to intubation and general weakness. We recommend the provision of nurse-led intensive care unit follow-up enabling patients to describe and discuss their intensive care unit experiences. © 2016 John Wiley & Sons Ltd.

Online faculty development for creating E-learning materials.

PubMed

Niebuhr, Virginia; Niebuhr, Bruce; Trumble, Julie; Urbani, Mary Jo

2014-01-01

Faculty who want to develop e-learning materials face pedagogical challenges of transforming instruction for the online environment, especially as many have never experienced online learning themselves. They face technical challenges of learning new software and time challenges of not all being able to be in the same place at the same time to learn these new skills. The objective of the Any Day Any Place Teaching (ADAPT) faculty development program was to create an online experience in which faculty could learn to produce e-learning materials. The ADAPT curriculum included units on instructional design, copyright principles and peer review, all for the online environment, and units on specific software tools. Participants experienced asynchronous and synchronous methods, including a learning management system, PC-based videoconferencing, online discussions, desktop sharing, an online toolbox and optional face-to-face labs. Project outcomes were e-learning materials developed and participants' evaluations of the experience. Likert scale responses for five instructional units (quantitative) were analyzed for distance from neutral using one-sample t-tests. Interview data (qualitative) were analyzed with assurance of data trustworthiness and thematic analysis techniques. Participants were 27 interprofessional faculty. They evaluated the program instruction as easy to access, engaging and logically presented. They reported increased confidence in new skills and increased awareness of copyright issues, yet continued to have time management challenges and remained uncomfortable about peer review. They produced 22 new instructional materials. Online faculty development methods are helpful for faculty learning to create e-learning materials. Recommendations are made to increase the success of such a faculty development program.

NEUTRON SHIELDING STRUCTURE

DOEpatents

Mattingly, J.T.

1962-09-25

A lightweight neutron shielding structure comprises a honeycomb core which is filled with a neutron absorbing powder. The honeycomb core is faced with parallel planar facing sheets to form a lightweight rigid unit. Suitable absorber powders are selected from among the following: B, B/sub 4/C, B/sub 2/O/ sub 3/, CaB/sub 6/, Li/sub 2/CO3, LiOH, LiBO/sub 2/, Li/s ub 2/O. The facing sheets are constructed of a neutron moderating material, so that fast neutrons will be moderated while traversing the facing sheets, and ultimately be absorbed by the absorber powder in the honeycomb. Beryllium is a preferred moderator material for use in the facing sheets. The advantage of the structure is that it combines the rigidity and light weight of a honeycomb construction with the neutron absorption properties of boron and lithium. (AEC)

Postdeployment reintegration experiences of female soldiers from national guard and reserve units in the United States.

PubMed

Kelly, Patricia J; Berkel, LaVerne A; Nilsson, Johanna E

2014-01-01

Women are an integral part of Reserve and National Guard units and active duty armed forces of the United States. Deployment to conflict and war zones is a difficult experience for both soldiers and their families. On return from deployment, all soldiers face the challenge of reintegration into family life and society, but those from the National Guard and Reserve units face the additional challenge of reintegration in relative isolation from other soldiers. There is limited research about the reintegration experiences of women and the functioning of the families during reintegration following deployment. The goal was to document postdeployment family reintegration experiences of women in the National Guard. Semistructured interviews were conducted with 42 female members of Midwestern National Guard units. Directed content analysis was used to identify categories of experiences related to women's family reintegration. Five categories of postdeployment experience for female soldiers and their families were identified: Life Is More Complex, Loss of Military Role, Deployment Changes You, Reestablishing Partner Connections, and Being Mom Again. The categories reflected individual and family issues, and both need to be considered when soldiers and their families seek care. Additional research is needed to fully understand the specific impact of gender on women's reintegration.

Congenital blindness improves semantic and episodic memory.

PubMed

Pasqualotto, Achille; Lam, Jade S Y; Proulx, Michael J

2013-05-01

Previous studies reported that congenitally blind people possess superior verb-generation skills. Here we tested the impact of blindness on capacity and the fidelity of semantic memory by using a false memory paradigm. In the Deese-Roediger-McDermott paradigm, participants study lists of words that are all semantically related to a lure that is not presented. Subsequently, participants frequently recall the missing lure. We found that congenitally blind participants have enhanced memory performance for recalling the presented words and reduced false memories for the lure. The dissociation of memory capacity and fidelity provides further evidence for enhanced verbal ability in the blind, supported by their broader structural and functional brain reorganisation.

State estimator for multisensor systems with irregular sampling and time-varying delays

NASA Astrophysics Data System (ADS)

Peñarrocha, I.; Sanchis, R.; Romero, J. A.

2012-08-01

This article addresses the state estimation in linear time-varying systems with several sensors with different availability, randomly sampled in time and whose measurements have a time-varying delay. The approach is based on a modification of the Kalman filter with the negative-time measurement update strategy, avoiding running back the full standard Kalman filter, the use of full augmented order models or the use of reorganisation techniques, leading to a lower implementation cost algorithm. The update equations are run every time a new measurement is available, independently of the time when it was taken. The approach is useful for networked control systems, systems with long delays and scarce measurements and for out-of-sequence measurements.

The Fatality Assessment and Control Evaluation program's role in the prevention of occupational fatalities.

PubMed

Higgins, D N; Casini, V J; Bost, P; Johnson, W; Rautiainen, R

2001-09-01

The objective of the Fatality Assessment and Control Evaluation (FACE) program is to prevent traumatic occupational fatalities in the United States by identifying and investigating work situations at high risk for injury and formulating and disseminating prevention strategies to those who can intervene in the workplace. The FACE program is a research program located in the Division of Safety Research, a division of the National Institute for Occupational Safety and Health (NIOSH). NIOSH is an agency of the United States government and is part of the Centers for Disease Control and Prevention. NIOSH is responsible for conducting research and making recommendations for prevention of work related illnesses and injuries. FACE investigators conduct traumatic occupational fatality investigations throughout the United States and provide technical assistance to 15 state health or labor departments who have cooperative agreements with NIOSH to conduct traumatic fatality surveillance, targeted investigations, and prevention activities at the state level. Investigations are conducted at the worksite using the FACE model, an approach derived from the research conducted by William Haddon Jr. This approach reflects the public health perspective that the etiology of injuries is multifactorial and largely preventable. FACE investigators gather information on multiple factors that may have contributed to traumatic occupational fatalities. Information on factors associated with the agent (energy exchange, for example, thermal energy, mechanical energy, electrical energy, chemical energy), host (worker who died), and the environment (the physical and social aspects of the workplace), during the pre-event, event, and post-event time phases of the fatal incident are collected and analyzed. Organizational, behavioral, and environmental factors contributing to the death are detailed and prevention recommendations formulated and disseminated to help prevent future incidents of a similar nature. Between 1982 and the present, more than 1,500 fatality investigations have been conducted and reports with prevention recommendations distributed. Findings have been published in scientific and trade journals; safety professionals and policy makers have used FACE findings for prevention efforts; and working partnerships have been formed to address newly emerging safety concerns. FACE investigations identify multiple factors contributing to fatal occupational injuries, which lead to the formulation and dissemination of diverse strategies for preventing deaths of a similar nature.

Aydon, Laurene; Hauck, Yvonne; Murdoch, Jamee; Siu, Daphne; Sharp, Mary

2018-01-01

To explore the experiences of parents with babies born between 28-32 weeks' gestation during transition through the neonatal intensive care unit and discharge to home. Following birth of a preterm baby, parents undergo a momentous journey through the neonatal intensive care unit prior to their arrival home. The complexity of the journey varies on the degree of prematurity and problems faced by each baby. The neonatal intensive care unit environment has many stressors and facilitating education to assist parents to feel ready for discharge can be challenging for all health professionals. Qualitative descriptive design. The project included two phases, pre- and postdischarge, to capture the experiences of 20 couples (40 parents), whilst their baby was a neonatal intensive care unit inpatient and then after discharge. Face-to-face interviews, an online survey and telephone interviews were employed to gather parent's experiences. Constant comparative analysis was used to identify commonalities between experiences. Recruitment and data collection occurred from October 2014-February 2015. Overlapping themes from both phases revealed three overarching concepts: effective parent staff communication; feeling informed and involved; and being prepared to go home. Our findings can be used to develop strategies to improve the neonatal intensive care unit stay and discharge experience for parents. Proposed strategies would be to improve information transfer, promote parental contact with the multidisciplinary team, encourage input from fathers to identify their needs and facilitate parental involvement according to individual needs within families. Providing information to parents during their time in hospital, in a consistent and timely manner is an essential component of their preparation when transitioning to home. © 2017 John Wiley & Sons Ltd.

Modular multi-element high energy particle detector

Multi-element high energy particle detector modules comprise a planar heavy metal carrier of tungsten alloy with planar detector units uniformly distributed over one planar surface. The detector units are secured to the heavy metal carrier by electrically conductive adhesive so that the carrier serves as a common ground. The other surface of each planar detector unit is electrically connected to a feedthrough electrical terminal extending through the carrier for front or rear readout. The feedthrough electrical terminals comprise sockets at one face of the carrier and mating pins porjecting from the other face, so that any number of modules may be plugged together to create a stack of modules of any desired number of radiation lengths. The detector units each comprise four, preferably rectangular, p-i-n diode chips arranged around the associated feedthrough terminal to form a square detector unit providing at least 90% detector element coverage of the carrier.

In Adult Mental Health Inpatient Units, it is not unexpected that leadership of Associate Nurse Unit Managers contributes to successful implementation of smoke-free policies. In light of challenges facing mental health nursing, and limited research describing their leadership and the role it plays in addressing smoke-free policy implementation, the aim of this study is to explore Associate Nurse Unit Managers perspectives' regarding the implementation of smoke-free policies, which were introduced on 1 July, 2015. Individual in-depth semi-structured interviews were undertaken six months post the implementation of smoke-free policies. In this qualitative descriptive study, six Associate Nurse Unit Managers working in a Victorian public Adult Mental Health Inpatient Unit, were asked eight questions which targeted leadership and the implementation and enforcement of smoke-free policies. Associate Nurse Unit Managers provide leadership and role modeling for staff and they are responsible for setting the standards that govern the behavior of nurses within their team. All participants interviewed believed that they were leaders in the workplace. Education and consistency were identified as crucial for smoke-free policies to be successful. Participants acknowledged that the availability of therapeutic interventions, staff resources and the accessibility of nicotine replacement therapy were crucial to assist consumers to remain smoke-free while on the unit. The findings from this research may help to improve the understanding of the practical challenges that Associate Nurse Unit Manager's face in the implementation of smoke-free policies with implications for policies, nursing practice, education and research.

Three dimensional metafilms with dual channel unit cells

2017-04-04

Three-dimensional (3D) metafilms composed of periodic arrays of silicon unit cells containing single and multiple micrometer-scale vertical split ring resonators (SRRs) per unit cell were fabricated. In contrast to planar and stacked planar structures, these 3D metafilms have a thickness t ~λ d/4, allowing for classical thin film effects in the long wavelength limit. The infrared specular far-field scattering response was measured for metafilms containing one and two resonators per unit cell and compared to numerical simulations. Excellent agreement in the frequency region below the onset of diffractive scattering was obtained. For dense arrays of unit cells containing single SRRs,more » normally incident linearly polarized plane waves which do not excite a resonant response result in thin film interference fringes in the reflected spectra and are virtually indistinguishable from the scattering response of an undecorated array of unit cells. For the resonant linear polarization, the specular reflection for arrays is highly dependent on the SRR orientation on the vertical face for gap-up, gap-down, and gap-right orientations. For dense arrays of unit cells containing two SRRs per unit cell positioned on adjacent faces, the specular reflection spectra are slightly modified due to near-field coupling between the orthogonally oriented SRRs but otherwise exhibit reflection spectra largely representative of the corresponding single-SRR unit cell structures. Lastly, the ability to pack the unit cell with multiple inclusions which can be independently excited by choice of incident polarization suggests the construction of dual-channel films where the scattering response is selected by altering the incident polarization.« less

Health technology assessment (HTA) carried out for policy decision making has well-established principles unlike hospital-based HTA (HB-HTA), which differs from the former in the context characteristics and ways of operation. This study proposes principles for good practices in HB-HTA units. A framework for good practice criteria was built inspired by the EFQM excellence business model and information from six literature reviews, 107 face-to-face interviews, forty case studies, large-scale survey, focus group, Delphi survey, as well as local and international validation. In total, 385 people from twenty countries have participated in defining the principles for good practices in HB-HTA units. Fifteen guiding principles for good practices in HB-HTA units are grouped in four dimensions. Dimension 1 deals with principles of the assessment process aimed at providing contextualized information for hospital decision makers. Dimension 2 describes leadership, strategy and partnerships of HB-HTA units which govern and facilitate the assessment process. Dimension 3 focuses on adequate resources that ensure the operation of HB-HTA units. Dimension 4 deals with measuring the short- and long-term impact of the overall performance of HB-HTA units. Finally, nine core guiding principles were selected as essential requirements for HB-HTA units based on the expertise of the HB-HTA units participating in the project. Guiding principles for good practices set up a benchmark for HB-HTA because they represent the ideal performance of HB-HTA units; nevertheless, when performing HTA at hospital level, context also matters; therefore, they should be adapted to ensure their applicability in the local context.

Borges, Guilherme; Medina-Mora, Maria Elena; Breslau, Joshua; Aguilar-Gaxiola, Sergio

2007-10-01

We examined the association between substance use disorders and migration to the United States in a nationally representative sample of the Mexican population. We used the World Mental Health version of the Composite International Diagnostic Interview to conduct structured, computer-assisted, face-to-face interviews with a cross-sectional sample of household residents aged 18 to 65 years who lived in Mexico in cities with a population of at least 2500 people in 2001 and 2002. The response rate was 76.6%, with 5826 respondents interviewed. Respondents who had migrated to the United States and respondents who had family members who migrated in the United States were more likely to have used alcohol, marijuana, or cocaine at least once in their lifetime; to develop a substance use disorder; and to have a current (in the past 12 months) substance use disorder than were other Mexicans. International migration appears to play a large role in transforming substance use norms and pathology in Mexico. Future studies should examine how networks extending over international boundaries influence substance use.

Effects of configural processing on the perceptual spatial resolution for face features.

PubMed

Namdar, Gal; Avidan, Galia; Ganel, Tzvi

2015-11-01

Configural processing governs human perception across various domains, including face perception. An established marker of configural face perception is the face inversion effect, in which performance is typically better for upright compared to inverted faces. In two experiments, we tested whether configural processing could influence basic visual abilities such as perceptual spatial resolution (i.e., the ability to detect spatial visual changes). Face-related perceptual spatial resolution was assessed by measuring the just noticeable difference (JND) to subtle positional changes between specific features in upright and inverted faces. The results revealed robust inversion effect for spatial sensitivity to configural-based changes, such as the distance between the mouth and the nose, or the distance between the eyes and the nose. Critically, spatial resolution for face features within the region of the eyes (e.g., the interocular distance between the eyes) was not affected by inversion, suggesting that the eye region operates as a separate 'gestalt' unit which is relatively immune to manipulations that would normally hamper configural processing. Together these findings suggest that face orientation modulates fundamental psychophysical abilities including spatial resolution. Furthermore, they indicate that classic psychophysical methods can be used as a valid measure of configural face processing. Copyright © 2015 Elsevier Ltd. All rights reserved.

Causal-comparative study analyzing student success in hybrid anatomy and physiology courses

NASA Astrophysics Data System (ADS)

Levy, Jacqueline Anita

In the biological sciences, higher student success levels are achieved in traditionally formatted, face-to-face coursework than in hybrid courses. The methodologies used to combine hybrid and in-person elements to the course need to be applied to the biological sciences to emulate the success seen in the traditional courses since the number of hybrid course offerings at community colleges are rapidly increasing. Research has delineated that creating online collaborative communities and increasing student engagement all function to increase student successful outcomes. This causal-comparative study was conducted using student data from four sections of hybrid, introductory anatomy and physiology courses over the 2011 and 2012 calendar years. The study included two sources of data: unit exam scores and student surveys. Analysis of the unit exam scores determined that there were statistically significant differences in student success and achievement by the implementation of the following web-enhanced technologies: a) discussion boards, b) Breeze, and c) Wiki tools. In the scope of this study, student success and achievement was defined as a student earning a C (70%) or higher at the completion of the course. There were a total of 29 surveys conducted per each unit during the 2012 semesters that related to the web-enhanced technologies implemented into the course: Discussion boards, BreezeRTM, and Wiki tools. Demographic data was also compiled on all of the students enrolled in the classes during this study to demonstrate that there is no specified niche or trend seen in the students enrolling for this particular course. Unit 1 was used as a baseline to compare the students from the two years. It was determined that the students were not significantly different in aptitude levels at the beginning of the courses based on their Unit 1 exam scores. Inferential statistical analysis was done to examine student success and achievement using the following tools: t-test of independent means of the variables, mean, standard deviation, and magnitude of effect. The findings of this study indicate that the web-enhanced technology Wiki tools provided the largest increase in student success and achievement in the hybrid, introductory anatomy and physiology course. Descriptive analysis of the surveys revealed that more than a third of each class felt that the implemented web-enhanced technology functioned to increase collaboration amongst the students and helped to emulate a traditional, face-to-face formatted course. The study included four recommendations for practice and nine recommendations for further research. A couple of recommendations for practice included using a single web-enhanced technology for the duration of the semester and having instructors and students complete tutorial sessions for the chosen technology being implemented. Examples of recommendations for research include replicating this study at other institutions and comparing face-to-face, traditional classes to hybrid courses within the same STEM discipline.

Fuel cell assembly unit for promoting fluid service and electrical conductivity

Jones, Daniel O.

1999-01-01

Fluid service and/or electrical conductivity for a fuel cell assembly is promoted. Open-faced flow channel(s) are formed in a flow field plate face, and extend in the flow field plate face between entry and exit fluid manifolds. A resilient gas diffusion layer is located between the flow field plate face and a membrane electrode assembly, fluidly serviced with the open-faced flow channel(s). The resilient gas diffusion layer is restrained against entering the open-faced flow channel(s) under a compressive force applied to the fuel cell assembly. In particular, a first side of a support member abuts the flow field plate face, and a second side of the support member abuts the resilient gas diffusion layer. The support member is formed with a plurality of openings extending between the first and second sides of the support member. In addition, a clamping pressure is maintained for an interface between the resilient gas diffusion layer and a portion of the membrane electrode assembly. Preferably, the support member is spikeless and/or substantially flat. Further, the support member is formed with an electrical path for conducting current between the resilient gas diffusion layer and position(s) on the flow field plate face.

This study examined the way communities respond to plans aimed at reorganising emergency services, including the trade-offs inherent in such decisions. Design Cross-sectional study involving in-depth interviews. Participants selected their priorities for emergency care, including aspects they might be prepared to have ‘less’ of (e.g. rapid access) if it meant having ‘more’ of another (e.g. consultant-delivered care). A thematic analysis was carried out, combining inductive and deductive approaches, drawing on theories about risk perception. Setting Two urban areas of England; one where changes to emergency services were under consideration (‘Greenville’), and one where they were not (‘Hilltown’). Participants 28 participants in total. Greenville interviewees included more common emergency service users - parents of young children (n=5) and older people (n=6) - plus patient representatives and individuals campaigning against service closures (n=9). Hilltown interviewees (n=8) received outpatient care for Chronic Obstructive Pulmonary Disease, an important cause of emergency admission. Results Most participants, in both areas, were not willing to accommodate the trade-offs involved in consolidating emergency services, principally because of the belief that timely access is associated with better outcomes. Participants did not consider the proposed improvements as gains worth having; interviewees believed care quality would be adversely impact, partly because increased patient numbers would place staff under greater pressure and result in longer waiting times. Conclusions Visible clinical leadership and detailed explanation of the case for change were insufficient to overcome opposition to the reconfiguration in Greenville, challenging the assumption that communities can be persuaded by evidence. Commissioners should make explicit credible plans to accommodate changes in patient flows, as well as clarifying the roles played by key staff groups. PMID:25807143

2012-07-01

A randomised controlled trial was used to evaluate elective ambulatory orthopaedic surgery patients' emotions during internet-based patient education or face-to-face education with a nurse. The internet-based patient education was designed for this study and patients used websites individually based on their needs. Patients in the control group participated individually in face-to-face patient education with a nurse in the ambulatory surgery unit. The theoretical basis for both types of education was the same. Ambulatory orthopaedic surgery patients scored their emotions rather low at intervals throughout the whole surgical process, though their scores also changed during the surgical process. Emotion scores did not decrease after patient education. No differences in patients' emotions were found to result from either of the two different patient education methods.

The Invisible Army

ABSTRACT The “invisible army” of clinical microbiologists is facing major changes and challenges. The rate of change in both the science and technology is accelerating with no end in sight, putting pressure on our army to learn and adapt as never before. Health care funding in the United States is undergoing dramatic change which will require a new set of assumptions about how clinical microbiology is practiced here. A major challenge facing the discipline is the replacement of a generation of clinical microbiologists. In my opinion, it is incumbent on us in the invisible army to continue to work with the American Society for Microbiology (ASM) in meeting the future challenges faced by our discipline. In this commentary, I will first discuss some recent history of clinical microbiology within ASM and then some current challenges we face. PMID:28659316

Experimental Study of Convective Heating on the Back Face and Payload of a Hypersonic Inflatable Aerodynamic Decelerator (HIAD) Aeroshell

Hollis, Brian R.; Berry, Scott A.; Hollingsworth, Kevin E.; Wright, Sheila A.

2017-01-01

A wind tunnel test program has been conducted to define convective heating environments on the back-face of a Hypersonic Inflatable Aerodynamic Decelerator aeroshell. Wind tunnel testing was conducted at Mach 6 and Mach 10 at unit Reynolds numbers from 0.5×10(exp 6)/ft to 3.9×10(exp 6)/ft on a 6.3088 in diameter aeroshell model. Global heating data were obtained through phosphor thermography on the aeroshell back face, as well as on the payload and the aeroshell front face. For all test conditions, laminar flow was produced on the aeroshell front face, while the separated wake shear layer and aeroshell back-face boundary layer were transitional or turbulent. Along the leeward centerline of the aeroshell back face and payload centerbody, heating levels increased with both free stream Reynolds number and angle of attack. The Reynolds number dependency was due to increasing strength of wake turbulence with Reynolds number. The angle-of-attack dependency was due to movement of the wake-vortex reattachment point on the aeroshell back face. The maximum heating levels on the aeroshell back face and payload were approximately 5% to 6%, respectively, of the aeroshell front-face stagnation point. To allow for extrapolation of the ground test data to flight conditions, the back face and payload heating levels were correlated as a function of aeroshell front-face peak momentum thickness Reynolds numbers.

Objectives This study compared admission rates to a United States anesthesiology residency program for applicants completing face-to-face versus web-based interviews during the admissions process. We also explored factors driving applicants to select each interview type. Methods The 211 applicants invited to interview for admission to our anesthesiology residency program during the 2014-2015 application cycle were participants in this pilot observational study. Of these, 141 applicants selected face-to-face interviews, 53 applicants selected web-based interviews, and 17 applicants declined to interview. Data regarding applicants' reasons for selecting a particular interview type were gathered using an anonymous online survey after interview completion. Residency program admission rates and survey answers were compared between applicants completing face-to-face versus web-based interviews. Results One hundred twenty-seven (75.1%) applicants completed face-to-face and 42 (24.9%) completed web-based interviews. The admission rate to our residency program was not significantly different between applicants completing face-to-face versus web-based interviews. One hundred eleven applicants completed post-interview surveys. The most common reasons for selecting web-based interviews were conflict of interview dates between programs, travel concerns, or financial limitations. Applicants selected face-to-face interviews due to a desire to interact with current residents, or geographic proximity to the residency program. Conclusions These results suggest that completion of web-based interviews is a viable alternative to completion of face-to-face interviews, and that choice of interview type does not affect the rate of applicant admission to the residency program. Web-based interviews may be of particular interest to applicants applying to a large number of programs, or with financial limitations. PMID:27039029

Nurse managers face significant pressures in the rapidly changing healthcare environment. Staying current with multiple sources of data, including reports that detail institutional and unit performance outcomes, is particularly challenging. A Nurse Manager Customized Profile was developed at a western academic hospital to provide a 1-page visual of pertinent data to help managers and director supervisors focus coaching to improve unit performance. Use of the Decisional Involvement Scale provided new insights into measuring manager performance.

Combinatorial compatibility as habit-controlling factor in lysozyme crystallization I. Monomeric and tetrameric F faces derived graph-theoretically

1997-03-01

A series of two articles discusses possible morphological evidence for oligomerization of growth units in the crystallization of tetragonal lysozyme, based on a rigorous graph-theoretic derivation of the F faces. In the first study (Part I), the growth layers are derived as valid networks satisfying the conditions of F slices in the context of the PBC theory using the graph-theoretic method implemented in program FFACE [C.S. Strom, Z. Krist. 172 (1985) 11]. The analysis is performed in monomeric and alternative tetrameric and octameric formulations of the unit cell, assuming tetramer formation according to the strongest bonds. F (flat) slices with thickness Rdhkl ( {1}/{2} < R ≤ 1 ) are predicted theoretically in the forms 1 1 0, 0 1 1, 1 1 1. The relevant energies are established in the broken bond model. The relation between possible oligomeric specifications of the unit cell and combinatorially feasible F slice compositions in these orientations is explored.

A Case Study of Exploring Older Chinese Immigrants' Social Support within a Chinese Church Community in the United States.

2016-09-01

The number of older Chinese immigrants living in the United States is increasing steadily. They are faced with challenges to meet their needs for social support and are unlikely to turn to formal services. This case study utilizes an ecological framework to analyze social support among Chinese immigrants age 65 year and older within a Christian Chinese church community, and to explore the ways in which a Chinese church functions as the source of social support for older Chinese immigrants. Seven months of participant observation and ten face-to-face, in-depth interviews were conducted with 65+ Chinese adults who attended one Chinese church in the Southern United State and included questions concerning patterns of support and personal relationships within the church. Findings revealed that gender, living arrangements, working experiences, ability to drive, and English language skills were related to support the older Chinese immigrants sought, received, and provided. Although the Chinese church can be a viable source of supplementary support, some participants in this study felt the support they received from the church was insufficient, particularly in terms of emotional support. Therefore, suggestions are outlined that may assist Chinese churches to be more proactive in better understanding and providing services that meet the different needs and desires of older Chinese immigrants.

From partial to full-face transplantation: total ablation and restoration, a change in the reconstructive paradigm.

PubMed

Barret, Juan P

2014-01-01

The innovation of composite vascularized allotransplantation has provided plastic and reconstructive surgeons with the ultimate tool for those patients that present with facial deformities that cannot be reconstructed with classical or more traditional techniques. Transplanting normal tissues allows for a true restorative surgery. Initial experiences included the substitution of missing anatomy, whereas after the first world's full-face transplant performed in Barcelona in March 2010, a true ablative surgery with a total restoration proved to be effective. We review the world's experience and the performance of our restorative protocol to depict this change in the reconstructive paradigm of facial transplantation. Facial transplants should be performed after a careful analysis of the defect, with a comprehensive ablation plan following esthetic units with sacrifice of all required tissues with a focus of global restoration of anatomy, aesthetics and function, respecting normal functioning muscles. Nowadays, facial transplants following strict esthetic units should restore disfigurement extending to small central areas, whereas major defects may require a total ablation and restoration with full-face transplants.

Structural building principles of complex face-centered cubic intermetallics.

PubMed

Dshemuchadse, Julia; Jung, Daniel Y; Steurer, Walter

2011-08-01

Fundamental structural building principles are discussed for all 56 known intermetallic phases with approximately 400 or more atoms per unit cell and space-group symmetry F43m, Fd3m, Fd3, Fm3m or Fm3c. Despite fundamental differences in chemical composition, bonding and electronic band structure, their complex crystal structures show striking similarities indicating common building principles. We demonstrate that the structure-determining elements are flat and puckered atomic {110} layers stacked with periodicities 2p. The atoms on this set of layers, which intersect each other, form pentagon face-sharing endohedral fullerene-like clusters arranged in a face-centered cubic packing (f.c.c.). Due to their topological layer structure, all these crystal structures can be described as (p × p × p) = p(3)-fold superstructures of a common basic structure of the double-diamond type. The parameter p, with p = 3, 4, 7 or 11, is determined by the number of layers per repeat unit and the type of cluster packing, which in turn are controlled by chemical composition.

Nematomorph parasites indirectly alter the food web and ecosystem function of streams through behavioural manipulation of their cricket hosts.

Nematomorph parasites manipulate crickets to enter streams where the parasites reproduce. These manipulated crickets become a substantial food subsidy for stream fishes. We used a field experiment to investigate how this subsidy affects the stream community and ecosystem function. When crickets were available, predatory fish ate fewer benthic invertebrates. The resulting release of the benthic invertebrate community from fish predation indirectly decreased the biomass of benthic algae and slightly increased leaf break-down rate. This is the first experimental demonstration that host manipulation by a parasite can reorganise a community and alter ecosystem function. Nematomorphs are common, and many other parasites have dramatic effects on host phenotypes, suggesting that similar effects of parasites on ecosystems might be widespread. © 2012 Blackwell Publishing Ltd/CNRS.

Particle Based Simulations of Complex Systems with MP2C : Hydrodynamics and Electrostatics

Sutmann, Godehard; Westphal, Lidia; Bolten, Matthias

2010-09-01

Particle based simulation methods are well established paths to explore system behavior on microscopic to mesoscopic time and length scales. With the development of new computer architectures it becomes more and more important to concentrate on local algorithms which do not need global data transfer or reorganisation of large arrays of data across processors. This requirement strongly addresses long-range interactions in particle systems, i.e. mainly hydrodynamic and electrostatic contributions. In this article, emphasis is given to the implementation and parallelization of the Multi-Particle Collision Dynamics method for hydrodynamic contributions and a splitting scheme based on Multigrid for electrostatic contributions. Implementations are done for massively parallel architectures and are demonstrated for the IBM Blue Gene/P architecture Jugene in Jülich.

2011-11-01

We present a comparative experimental evaluation of the Butler-Volmer and Marcus-Hush models using cyclic voltammetry at a microelectrode. Numerical simulations are used to fit experimental voltammetry of the one electron reductions of europium (III) and 2-methyl-2-nitropropane, in water and acetonitrile, respectively, at a mercury microhemisphere electrode. For Eu (III) very accurate fits to experiment were obtained over a wide range of scan rates using Butler-Volmer kinetics, whereas the Marcus-Hush model was less accurate. The reduction of 2-methyl-2-nitropropane was well simulated by both models, however Marcus-Hush required a reorganisation energy lower than expected.

Multi-agent cooperation pursuit based on an extension of AALAADIN organisational model

2016-11-01

An approach of cooperative pursuit for multiple mobile targets based on multi-agents system is discussed. In this kind of problem the pursuit process is divided into two kinds of tasks. The first one (coalition problem) is designed to solve the problem of the pursuit team formation. To achieve this mission, we used an innovative method based on a dynamic organisation and reorganisation of the pursuers' groups. We introduce our coalition strategy extended from the organisational agent, group, role model by assigning an access mechanism to the groups inspired by fuzzy logic principles. The second task (motion problem) is the treatment of the pursuers' motion strategy. To manage this problem we applied the principles of the Markov decision process. Simulation results show the feasibility and validity of the given proposal.

2010-01-01

This article identifies the nature of functions that social service workers employed by municipal organisations have to perform during a community disaster and subsequent reorganisation at a time of war. The article also explores to what extent the functions of workers change as a result of the transition from a peacetime routine to a war situation. Using focus groups the study assesses the knowledge of social service workers and ordinary citizens who had direct experience of the second Lebanese war in Israel (2006). Eight major functions needed at a time of disaster are distinguished among various employees. The article discusses the significance of these functions, and the need to make changes in the network of functions at a time of disaster.

How Memory Replay in Sleep Boosts Creative Problem-Solving.

PubMed

Lewis, Penelope A; Knoblich, Günther; Poe, Gina

2018-06-01

Creative thought relies on the reorganisation of existing knowledge. Sleep is known to be important for creative thinking, but there is a debate about which sleep stage is most relevant, and why. We address this issue by proposing that rapid eye movement sleep, or 'REM', and non-REM sleep facilitate creativity in different ways. Memory replay mechanisms in non-REM can abstract rules from corpuses of learned information, while replay in REM may promote novel associations. We propose that the iterative interleaving of REM and non-REM across a night boosts the formation of complex knowledge frameworks, and allows these frameworks to be restructured, thus facilitating creative thought. We outline a hypothetical computational model which will allow explicit testing of these hypotheses. Copyright © 2018. Published by Elsevier Ltd.

Cancer cell invasion is a critical phenomenon in cancer pathogenesis. Glycogen synthase kinase-3β (GSK-3β) has been reported to regulate cancer cell invasion both negatively and positively. Thus, the net effect of GSK-3β on invasion is unclear. In this report, we showed that GSK-3β inhibitors induced dysregulation of the actin cytoskeleton and functional insufficiency of focal adhesion, which resulted in suppressed invasion. In addition, WAVE2, an essential molecule for actin fibre branching, was down-regulated after GSK-3β inhibition. Collectively, we propose that the WAVE2-actin cytoskeleton axis is an important target of GSK-3β inhibitors in cancer cell invasion. Copyright © 2015 Elsevier Inc. All rights reserved.

Objectives. We examined the association between substance use disorders and migration to the United States in a nationally representative sample of the Mexican population. Methods. We used the World Mental Health version of the Composite International Diagnostic Interview to conduct structured, computer-assisted, face-to-face interviews with a cross-sectional sample of household residents aged 18 to 65 years who lived in Mexico in cities with a population of at least 2500 people in 2001 and 2002. The response rate was 76.6%, with 5826 respondents interviewed. Results. Respondents who had migrated to the United States and respondents who had family members who migrated in the United States were more likely to have used alcohol, marijuana, or cocaine at least once in their lifetime; to develop a substance use disorder; and to have a current (in the past 12 months) substance use disorder than were other Mexicans. Conclusions. International migration appears to play a large role in transforming substance use norms and pathology in Mexico. Future studies should examine how networks extending over international boundaries influence substance use. PMID:17761563

The United States should forego a damage-limitation capability against China

NASA Astrophysics Data System (ADS)

Glaser, Charles L.

2017-11-01

Bottom Lines • THE KEY STRATEGIC NUCLEAR CHOICE. Whether to attempt to preserve its damage-limitation capability against China is the key strategic nuclear choice facing the United States. The answer is much less clear-cut than when the United States faced the Soviet Union during the Cold War. • FEASIBILITY OF DAMAGE LIMITATION. Although technology has advanced significantly over the past three decades, future military competition between the U.S. and Chinese forces will favor large-scale nuclear retaliation over significant damage limitation. • BENEFITS AND RISKS OF A DAMAGE-LIMITATION CAPABILITY. The benefits provided by a modest damage-limitation capability would be small, because the United States can meet its most important regional deterrent requirements without one. In comparison, the risks, which include an increased probability of accidental and unauthorized Chinese attacks, as well as strained U.S.—China relations, would be large. • FOREGO DAMAGE LIMITATION. These twin findings—the poor prospects for prevailing in the military competition, and the small benefits and likely overall decrease in U.S. security—call for a U.S. policy that foregoes efforts to preserve or enhance its damage-limitation capability.

Wildfire impacts on soil-water retention in the Colorado Front Range, United States

Ebel, Brian A.

2012-01-01

This work examined the plot-scale differences in soil-water retention caused by wildfire in the area of the 2010 Fourmile Canyon Fire in the Colorado Front Range, United States. We measured soil-water retention curves on intact cores and repacked samples, soil particle-size distributions, and organic matter content. Estimates were also made of plant-available water based on the soil-water retention curves. Parameters for use in soil-hydraulic property models were estimated; these parameters can be used in unsaturated flow modeling for comparing burned and unburned watersheds. The primary driver for measured differences in soil-water retention in burned and unburned soils was organic matter content and not soil-particle size distribution. The tendency for unburned south-facing soils to have greater organic matter content than unburned north-facing soils in this field area may explain why unburned south-facing soils had greater soil-water retention than unburned north-facing soils. Our results suggest that high-severity wildfire can “homogenize” soil-water retention across the landscape by erasing soil-water retention differences resulting from organic matter content, which for this site may be affected by slope aspect. This homogenization could have important implications for ecohydrology and plant succession/recovery in burned areas, which could be a factor in dictating the window of vulnerability of the landscape to flash floods and erosion that are a common consequence of wildfire.

Farber, Scott J; Kantar, Rami S; Diaz-Siso, J Rodrigo; Rodriguez, Eduardo D

2018-05-15

Face transplantation has evolved over the last 12 years into a safe and feasible reconstructive solution, with good aesthetic and functional outcomes for patients with severe facial defects who are not amenable to reconstruction through conventional and autologous approaches. Among patients who underwent face transplantation to date, a significant proportion did so following trauma, mostly ballistic and thermal injuries. It is therefore important for trauma surgeons who deal with these injuries regularly to be familiar with the literature on face transplantation following traumatic injuries. In this study, we provide a focused review on this topic, with an emphasis on highlighting the limitations of conventional craniomaxillofacial reconstruction, while emphasizing data available on the risks, benefits, surgical indications, contraindications, as well as aesthetic and functional outcomes of face transplantation. The authors also provide an update on all face transplants performed to date including traumatic mechanisms of injury, and extent of defects. They finally describe 2 cases performed by the senior author for patients presenting with devastating facial ballistic and thermal injuries. The authors hope that this work serves as an update for the trauma surgery community regarding the current role and limitations of face transplantation as a craniomaxillofacial reconstructive option for their patient population. This can potentially expedite the reconstructive process for patients who may benefit from face transplantation.

Virtual behavioral health (VBH) services are used frequently to address the high demand for behavioral health (BH) services in the military. Few studies have investigated the relationship between the use of VBH services and BH outcomes or preferences for the use of VBH technologies. In this article, we evaluated BH interviews conducted via video teleconferencing (VTC) or face-to-face in terms of BH symptoms, satisfaction rates, stigma, barriers to care, and preferences for future use of BH care. Soldiers (n = 307) from the headquarters element of an operational unit were surveyed 4 months following a 12-month deployment to Iraq. There were no significant differences in satisfaction rates based on interview modality, but significantly more soldiers preferred face-to-face interviews over VTC interviews in the future. Soldiers who preferred face-to-face interviews also reported higher levels of anxiety and depression symptoms than those who preferred VTC interviews. No significant age differences were found in terms of interview modality satisfaction or preference. Soldiers with greater deployment experience were more likely to report that they would not like using VTC if seeking BH care in the future than soldiers with less deployment experience. These findings highlight the importance of promoting choice in type of BH interview modality.

In this work, we investigated the morphology and growth rates of NaClO3 crystals in solutions with K2SO4 additives. NaClO3 crystals were grown using the temperature gradient technique under concentration convection. We found that the crystal habitus changed from cubic to tetrahedral, and the growth of the cubic {100}, tetrahedral {111} and rhomb-dodecahedral {110} faces decelerated with an increase in the concentration of SO42- ions. The {110} face was the most and the {100} face was the least inhibited by sulphate ions. The mechanism of SO42- ions action is their adsorption on the crystal surface, which impedes attachment of the crystal's building units. We conclude that different atomic structure and charge state of various crystal faces determine their sensitivity to the action of the SO42- ions.

Telemedicine in the Intensive Care Unit: Improved Access to Care at What Cost?

Binder, William J; Cook, Jennifer L; Gramze, Nickalaus; Airhart, Sophia

2018-06-01

Health systems across the United States are adopting intensive care unit telemedicine programs to improve patient outcomes. Research demonstrates the potential for decreased mortality and length of stay for patients of these remotely monitored units. Financial models and studies point to cost-effectiveness and the possibility of cost savings in the face of abundant startup costs. Questions remain as to the true financial implications of these programs and targeted populations that may see the greatest benefit. Despite recent growth, widespread adoption may be limited until these unknowns are answered. Copyright © 2018 Elsevier Inc. All rights reserved.

To determine if cropping facial images affects nasolabial aesthetics assessments in unilateral cleft lip patients and to evaluate the effect of facial attractiveness on nasolabial evaluation. Two cleft surgeons and one cleft orthodontist assessed standardized frontal photographs 4 times; nasolabial aesthetics were rated on cropped and full-face images using the Cleft Aesthetic Rating Scale, and total facial attractiveness was rated on full-face images with and without the nasolabial area blurred using a 5-point Likert scale. Cleft Palate Craniofacial Unit of a University Medical Center. Inclusion criteria: nonsyndromic unilateral cleft lip and an available frontal view photograph around 10 years of age. a history of facial trauma and an incomplete cleft. Eighty-one photographs were available for assessment. Differences in mean CARS scores between cropped versus full-face photographs and attractive versus unattractive rated patients were evaluated by paired t test. Nasolabial aesthetics are scored more negatively on full-face photographs compared to cropped photographs, regardless of facial attractiveness. (Mean CARS score, nose: cropped = 2.8, full-face = 3.0, P < .001; lip: cropped = 2.4, full-face = 2.7, P < .001; nose and lip: cropped = 2.6, full-face = 2.8, P < .001). Aesthetic outcomes of the nasolabial area are assessed significantly more positively when using cropped images compared to full-face images. For this reason, cropping images, revealing the nasolabial area only, is recommended for aesthetical assessments.

Defining the Cellular Environment in the Organ of Corti following Extensive Hair Cell Loss: A Basis for Future Sensory Cell Replacement in the Cochlea

PubMed Central

Taylor, Ruth R.; Jagger, Daniel J.; Forge, Andrew

2012-01-01

Background Following the loss of hair cells from the mammalian cochlea, the sensory epithelium repairs to close the lesions but no new hair cells arise and hearing impairment ensues. For any cell replacement strategy to be successful, the cellular environment of the injured tissue has to be able to nurture new hair cells. This study defines characteristics of the auditory sensory epithelium after hair cell loss. Methodology/Principal Findings Studies were conducted in C57BL/6 and CBA/Ca mice. Treatment with an aminoglycoside-diuretic combination produced loss of all outer hair cells within 48 hours in both strains. The subsequent progressive tissue re-organisation was examined using immunohistochemistry and electron microscopy. There was no evidence of significant de-differentiation of the specialised columnar supporting cells. Kir4.1 was down regulated but KCC4, GLAST, microtubule bundles, connexin expression patterns and pathways of intercellular communication were retained. The columnar supporting cells became covered with non-specialised cells migrating from the outermost region of the organ of Corti. Eventually non-specialised, flat cells replaced the columnar epithelium. Flat epithelium developed in distributed patches interrupting regions of columnar epithelium formed of differentiated supporting cells. Formation of the flat epithelium was initiated within a few weeks post-treatment in C57BL/6 mice but not for several months in CBA/Ca's, suggesting genetic background influences the rate of re-organisation. Conclusions/Significance The lack of dedifferentiation amongst supporting cells and their replacement by cells from the outer side of the organ of Corti are factors that may need to be considered in any attempt to promote endogenous hair cell regeneration. The variability of the cellular environment along an individual cochlea arising from patch-like generation of flat epithelium, and the possible variability between individuals resulting from genetic influences on the rate at which remodelling occurs may pose challenges to devising the appropriate regenerative therapy for a deaf patient.

Arsenic exposure disrupts epigenetic regulation of SIRT1 in human keratinocytes

DOE Office of Scientific and Technical Information (OSTI.GOV)

Herbert, Katharine J.; Holloway, Adele; Cook, Anthony L.

2014-11-15

Arsenic is an environmental toxin which increases skin cancer risk for exposed populations worldwide; however the underlying biomolecular mechanism for arsenic-induced carcinogenesis is complex and poorly defined. Recent investigations show that histone deacetylase and DNA methyltransferase activity is impaired, and epigenetic patterns of gene regulation are consistently altered in cancers associated with arsenic exposure. Expression of the histone deacetylase SIRT1 is altered in solid tumours and haematological malignancies; however its role in arsenic-induced pathology is unknown. In this study we investigated the effect of arsenic on epigenetic regulation of SIRT1 and its targeting microRNA, miR-34a in primary human keratinocytes. Acetylationmore » of histone H4 at lysine 16 (H4K16) increased in keratinocytes exposed to 0.5 μM arsenite [As(III)]; and this was associated with chromatin remodelling at the miR-34a promoter. Moreover, although SIRT1 protein initially increased in these As(III)-exposed cells, after 24 days expression was not significantly different from untreated controls. Extended exposure to low-dose As(III) (0.5 μM; > 5 weeks) compromised the pattern of CpG methylation at SIRT1 and miR-34a gene promoters, and this was associated with altered expression for both genes. We have found that arsenic alters epigenetic regulation of SIRT1 expression via structural reorganisation of chromatin at the miR-34a gene promoter in the initial 24 h of exposure; and over time, through shifts in miR-34a and SIRT1 gene methylation. Taken together, this investigation demonstrates that arsenic produces cumulative disruptions to epigenetic regulation of miR-34a expression, and this is associated with impaired coordination of SIRT1 functional activity. - Highlights: • Submicromolar arsenic concentrations disrupt SIRT1 activity and expression in human keratinocytes. • Arsenic-induced chromatin remodelling at the miR-34a gene promoter is associated with hyperacetylation of histone H4 (Lys 16). • Continual extended exposure to arsenic reorganises the pattern of SIRT1 and miR-34a promoter methylation.« less

Repetition suppression of faces is modulated by emotion

Ishai, Alumit; Pessoa, Luiz; Bikle, Philip C.; Ungerleider, Leslie G.

2004-06-01

Single-unit recordings and functional brain imaging studies have shown reduced neural responses to repeated stimuli in the visual cortex. By using event-related functional MRI, we compared the activation evoked by repetitions of neutral and fearful faces, which were either task relevant (targets) or irrelevant (distracters). We found that within the inferior occipital gyri, lateral fusiform gyri, superior temporal sulci, amygdala, and the inferior frontal gyri/insula, targets evoked stronger responses than distracters and their repetition was associated with significantly reduced responses. Repetition suppression, as manifested by the difference in response amplitude between the first and third repetitions of a target, was stronger for fearful than neutral faces. Distracter faces, regardless of their repetition or valence, evoked negligible activation, indicating top-down attenuation of behaviorally irrelevant stimuli. Our findings demonstrate a three-way interaction between emotional valence, repetition, and task relevance and suggest that repetition suppression is influenced by high-level cognitive processes in the human brain. face perception | functional MRI

Attitudes to face transplantation: results of a public engagement exercise at the Royal Society Summer Science Exhibition.

Hettiaratchy and Butler (Lancet 2002;360:5-6) framed face transplantation as the next logical step on the reconstructive ladder for severe facial injury, in particular, pan-facial burns. The procedure formed the basis for a Royal College of Surgeons of England working party report. Ethical, surgical, and psychological issues were identified as research priorities before face transplantation is attempted in the United Kingdom. Public engagement is a vital mechanism if people are to be informed about the risks and benefits of the technique and ultimately to be able to consent to either receiving or donating facial tissue. To sample public opinion about the procedure, 304 people attending the Royal Society Summer Science Exhibition were sampled by online questionnaire to determine their attitude toward face transplantation. Although people were more cautious about face transplantation when comparing this with solid-organ transplantation, most of the sample were in favor of the procedure, whether receiving a donor face or donating their own face after their death. Only 10% were against the idea in principle. Concerns about altered identity were not a barrier to face transplantation for 69% of the sample, with most people appropriately identifying the long-term problems of immunosuppression as the issue that most concerned them. There is a substantial population of people who, given the right circumstances, would contemplate face transplantation for themselves and would be willing to donate their own face for transplantation after their death.

To explore issues arising during preliminary stages of a research project in order to consider the feasibility of a midwife-led normal birthing unit in mainland China. Midwife-led normal birthing units, as a route to ensuring normality, have become a feature of western maternity care, but are unknown in China. Action research, using a qualitative descriptive approach, was performed. Data were collected at meetings, by non-participant observation and by face-to-face semi-structured interviews. Observation was undertaken in the midwife-led normal birthing unit and a standard care setting. Data analysis was by thematic analysis using constant comparison techniques. In the labour ward of a large general hospital in a major city, stakeholders included midwifery staff, managers, university staff and researchers. Childbearing women proved keen to use this service, but were unable to participate in the planning. The midwife-led normal birthing unit sought to provide one-to-one care in labour and support by a birth companion. Routine interventions were to be avoided. The midwives in the midwife-led normal birthing unit created a more suitable environment for supportive care. The midwives demonstrated high-quality communication skills. The woman's choice of position/mobility was limited. Difficulties with staffing were identified. The preliminary findings suggest that continuation of the project is feasible. The woman's role demonstrates passivity. The perception of staff shortage has serious implications. This action research project suggests that a study of a midwife-led normal birthing unit in China is feasible, with some attention to staffing issues.

2008-01-01

Men migrating to the United States are at high risk of acquiring HIV and spreading it to their wives and children in Mexico. Yet there is limited understanding of this phenomenon from the perspective of these men and their wives. This exploratory study used face-to-face interviews to gain insight into factors influencing the increased risk of Mexican men migrating to the United States for contracting HIV as well as the consequences of their infections on returning to Mexico. Transcripts from audiotaped interviews provided the data for analysis. Thematic analysis revealed two overall categories and six interrelated themes. Categories were HIV Risk and Living with HIV. Study themes included social isolation, lack of knowledge/denial, machismo, powerlessness, and making the best of it. Results provide new insight into the spread of HIV in rural Mexico.

Benino, Diana; Girardi, Antonia; Czarniak, Petra

2011-10-01

To examine student perceptions regarding online lectures and quizzes undertaken during a pharmaceutical practice course for first year undergraduate students enrolled in the Bachelor of Pharmacy course at an Australian University. The University uses a standard instrument to collect feedback from students regarding unit satisfaction. Data were collected for three different teaching modalities: traditional face-to-face, online and partially online. Descriptive statistics support that, from a student's perspective, partial online delivery is the preferred teaching methodology for an introductory pharmaceutical practice unit. This study has served to highlight that while there are a few points of significant difference between traditional and online teaching and learning, a combination of the two provides a reasonable avenue for teaching exploration. This result has implications for teaching practice generally, and within the pharmacy discipline, specifically.

2016-07-01

Objectives To examine perceptions, experiences, and attitudes towards breastfeeding among Hispanic women living in rural Washington State. Methods Twenty parous Hispanic women of low acculturation, aged 25-48 years and residents in rural Washington State participated in an exploratory, face-to-face interview. Interviews were audio-recorded, translated and transcribed, and analyzed using a thematic content analysis approach. Results Nine emergent themes were grouped into three overarching categories: (1) Breast is best; (2) Hispanic cultural and familial expectations to breastfeed; and (3) Adapting to life in the United States: cultural norms in conflict. Women said they were motivated to breastfeed because of their knowledge and observations of its health benefits for mother and child. They said breastfeeding is ingrained in their Hispanic cultural heritage, and infant feeding choices of female family members were particularly influential in women's own decision to breastfeed. Women said they experienced embarrassment about breastfeeding in the United States and as a result, often chose to initiate formula feeding as a complement so as to avoid feelings of shame. Additionally, they faced economic pressure to work, key barriers for continued breastfeeding among Hispanics in the United States. Conclusions for Practice Knowledge of the benefits of breastfeeding for mother and child and longstanding cultural practices of breastfeeding are not enough to encourage exclusive breastfeeding to 6 months among this rural Hispanic population. Continued support through family-level interventions as well as work place policies that encourage breastfeeding are needed for rural Hispanics to reach optimal breastfeeding rates.

A mineral survey concluded that the James River Face Wilderness, Virginia, had little promise for the occurrence of metallic mineral resources. Two major rock units in the area do contain large nonmetallic mineral resources of quartzite and shale that have been mined for silica products and for brick and expanded aggregate, respectively. Because large deposits of the same material are more easily available in nearby areas, demand for the deposits within the wilderness is highly unlikely. No energy resources were identified in the course of this study.

The establishment of the Norwegian Fractionation Project (Project) was of major importance in preserving national self-sufficiency when plasma, cryoprecipitate and small batch factor IX-concentrates were replaced by virus inactivated products in the last part of the 1980s. Fractionation was performed abroad by contract with Octapharma after tenders on the European market. All Norwegian blood banks (>50) participated in the Project. Total yearly production was 50-60 tons of mainly recovered plasma. From 1993 solvent detergent (SD) treated plasma has replaced other plasma for transfusion. The blood banks paid for the fractionation and/or viral inactivation process, while the plasma remained the property of the blood banks and the final products were returned to the blood banks. The Project sold surplus products to other Norwegian blood banks and the majority of the coagulation factor concentrates to The Institute of Haemophilia and Rikshospitalet University Hospital. Both plasma and blood bank quality was improved by the Project. Clinical experience with the products has been satisfactory and self-sufficiency has been achieved for all major plasma proteins and SD plasma, but a surplus exceeding 3 years consumption of albumin has accumulated due to decreasing clinical use.The Project has secured high yields of the fractionated products and the net income from the produced products is NOK 1115 (140 Euros or US dollars) per litre plasma. An increasing surplus of albumin and the possibility of significant sales abroad of currently not fractionated IVIgG, could lead to a reorganisation of the Project from that of a co-ordinator to a national plasma handling unit. This unit could buy the plasma from the blood banks and have the plasma fractionated by contract after tender, before selling the products back for cost recovery. The small blood banks could produce plasma for products for the Norwegian market, while surplus products from the larger blood banks which are certified for delivery of plasma for fractionation of products to be consumed in the European Community, could be sold on the international market.

assess a prototype for use on mobile devices that permits registering data for the Systemization of Nursing Care at a Neonatal Intensive Care Unit. an exploratory and descriptive study was undertaken, characterized as an applied methodological research, developed at a teaching hospital. the mobile technology the nurses at the Neonatal Intensive Care Unit use was positive, although some reported they faced difficulties to manage it, while others with experience in using mobile devices did not face problems to use it. The application has the functions needed for the Systematization of Nursing Care at the unit, but changes were suggested in the interface of the screens, some data collection terms and parameters the application offers. The main contributions of the software were: agility in the development and documentation of the systemization, freedom to move, standardization of infant assessment, optimization of time to develop bureaucratic activities, possibilities to recover information and reduction of physical space the registers occupy. prototype software for the Systemization of Nursing Care with mobile technology permits flexibility for the nurses to register their activities, as the data can be collected at the bedside.

A Micromechanics Finite Element Model for Studying the Mechanical Behavior of Spray-On Foam Insulation (SOFI)

Ghosn, Louis J.; Sullivan, Roy M.; Lerch, Bradley A.

2006-01-01

A micromechanics model has been constructed to study the mechanical behavior of spray-on foam insulation (SOFI) for the external tank. The model was constructed using finite elements representing the fundamental repeating unit of the SOFI microstructure. The details of the micromechanics model were based on cell observations and measured average cell dimensions discerned from photomicrographs. The unit cell model is an elongated Kelvin model (fourteen-sided polyhedron with 8 hexagonal and six quadrilateral faces), which will pack to a 100% density. The cell faces and cell edges are modeled using three-dimensional 20-node brick elements. Only one-eighth of the cell is modeled due to symmetry. By exercising the model and correlating the results with the macro-mechanical foam behavior obtained through material characterization testing, the intrinsic stiffness and Poisson s Ratio of the polymeric cell walls and edges are determined as a function of temperature. The model is then exercised to study the unique and complex temperature-dependent mechanical behavior as well as the fracture initiation and propagation at the microscopic unit cell level.

Automatic recognition of emotion using facial expressions in the presence of speech poses a unique challenge because talking reveals clues for the affective state of the speaker but distorts the canonical expression of emotion on the face. We introduce a corpus of acted emotion expression where speech is either present (talking) or absent (silent). The corpus is uniquely suited for analysis of the interplay between the two conditions. We use a multimodal decision level fusion classifier to combine models of emotion from talking and silent faces as well as from audio to recognize five basic emotions: anger, disgust, fear, happy and sad. Our results strongly indicate that emotion prediction in the presence of speech from action unit facial features is less accurate when the person is talking. Modeling talking and silent expressions separately and fusing the two models greatly improves accuracy of prediction in the talking setting. The advantages are most pronounced when silent and talking face models are fused with predictions from audio features. In this multi-modal prediction both the combination of modalities and the separate models of talking and silent facial expression of emotion contribute to the improvement. PMID:25525561

Botulinum toxin drugs: brief history and outlook.

Dressler, D

2016-03-01

The global botulinum toxin (BT) market is currently undergoing rapid changes: this may be the time to review the history and the future of BT drug development. Since the early 1990s Botox(®) and Dysport(®) dominated the international BT market. Later, Myobloc(®)/NeuroBloc(®), a liquid BT type B drug, came out, but failed. Xeomin(®) is the latest major BT drug. It features removal of complexing proteins and improved neurotoxin purity. Several new BT drugs are coming out of Korea, China and Russia. Scientific challenges for BT drug development include modification of BT's duration of action, its transdermal transport and the design of BT hybrid drugs for specific target tissues. The increased competition will change the global BT market fundamentally and a re-organisation according to large indication groups, such as therapeutic and cosmetic applications, might occur.

To analyse the dehospitalisation process at a general public hospital in Minas Gerais, Brazil, from the perspective of managers, health workers, users and their families. This is a qualitative, exploratory, descriptive study based on the principles of methodological and theoretical dialectics. The participants were 24 hospital health workers and 15 companions of users going through the process of dehospitalisation. Data were collected from April to June 2015 using semi-structured interviews and a field journal records and subsequently subjected to content analysis. Analysis of the empirical material led to the construction of the following categories: Dehospitalisation: viewpoint of the institution and Family organisation for the dehospitalisation process. The study reveals a deficiency in the implementation, systematisation, internal reorganisation and continuity of care after dehospitalisation. Current dehospitalisation strategies do not favour comprehensiveness and continuity of home care.

After Poland regained its independence in 1918, research units were set up to provide scientific assistance to the state health and epidemiological service then being created. Towards the end of 1918 The State Central Hygiene Institute was established and, following successive reorganisations, transformed into the State Hygiene Institute. It operated at Chocimska str. 24 throughout the entire pre-war period, adapting its organisational structure to current needs. As a state public-health institution, it tracked down sources of communicable diseases and the way they were spread, and conducted research to detect cases of Asian cholera and carriers of contagious diseases. It produced vaccinations of other biological products used in the treatment and prevention of epidemics and made a significant contribution to the war on communicable diseases. It also served as the central state institution in charge of inspecting the country's epidemiological condition as well as a scientific-research facility designed to maintain it at a suitable level in accordance with international norms. With various organisational modifications it survived World War Two, its continued existence being maintained by the German occupation authorities. Reactivated after the war it continues to function to this day at its old location - ulica Chocimska 24, where it serves as a scientific-research facility for health and epidemiological services transferred to a separate organisational structure after 1950. Health and sanitary stations became state institutions in charge of anti-epidemic campaigns and were responsible for the country's health and epidemiological situation. In 1954, the State Health Inspectorate co-operating with the Ministry of Health was set up. The State Hygiene Institute functions to this day and it is the supervisory, co-ordinating and scientific-research institution of the State Health and Epidemiological Service.

A critical ethnographic study of encounters between midwives and breast-feeding women in postnatal wards in England.

Dykes, Fiona

2005-09-01

To explore the nature of interactions between midwives and breast-feeding women within postnatal wards. A critical ethnographic study using participant observation and focused interviews. Two maternity units in Northern England, UK. 61 postnatal women and 39 midwives. The interactions between midwives and women were encompassed by the global theme of 'taking time and touching base'. However, most encounters were characterised by an absence of 'taking time' or 'touching base'. This related to midwives' experiences of temporal pressure and inability to establish relationality with women due to their working patterns. The global theme was underpinned by five organising themes: 'communicating temporal pressure'; 'routines and procedures'; 'disconnected encounters'; 'managing breast feeding'; and 'rationing information'. The organisational culture within the postnatal wards contributed to midwives experiencing profound temporal pressures and an inability to establish relationality with women. Within this context, the needs of breast-feeding women for emotional, esteem, informational and practical support were largely unmet. Transformative action is required to dramatically reorganise the provision of hospital-based, postnatal ward midwifery care in parts of the UK. This should include a re-conceptualisation of caring time, with recognition that midwives need sufficient time in order to give time to others. This, in turn, requires recognition that caring time is cyclical and rhythmical, allowing for relationality, sociability, mutuality and reciprocity. The midwifery staffing structure in postnatal wards needs to be reviewed, as it is unacceptable to midwives and service users for staff to be rapidly relocated according to other demands within the institution. Most radically, it is argued that now is the time to reconsider the suitability of the hospital as the place and space within which women commence their breast-feeding journey.

Physician communication in the operating room: expanding application of face-negotiation theory to the health communication context.

PubMed

Kirschbaum, Kristin

2012-01-01

Communication variables that are associated with face-negotiation theory were examined in a sample of operating-room physicians. A survey was administered to anesthesiologists and surgeons at a teaching hospital in the southwestern United States to measure three variables commonly associated with face-negotiation theory: conflict-management style, face concern, and self-construal. The survey instrument that was administered to physicians includes items that measured these three variables in previous face-negotiation research with slight modification of item wording for relevance in the medical setting. The physician data were analyzed using confirmatory factor analysis, Pearson's correlations, and t-tests. Results of this initial investigation showed that variables associated with face-negotiation theory were evident in the sample physician population. In addition, the correlations were similar among variables in the medical sample as those found in previous face-negotiation research. Finally, t-tests suggest variance between anesthesiologists and surgeons on specific communication variables. These findings suggest three implications that warrant further investigation with expanded sample size: (1) An intercultural communication theory and instrument can be utilized for health communication research; (2) as applied in a medical context, face-negotiation theory can be expanded beyond traditional intercultural communication boundaries; and (3) theoretically based communication structures applied in a medical context could help explain physician miscommunication in the operating room to assist future design of communication training programs for operating-room physicians.

Discrimination between smiling faces: Human observers vs. automated face analysis.

This study investigated (a) how prototypical happy faces (with happy eyes and a smile) can be discriminated from blended expressions with a smile but non-happy eyes, depending on type and intensity of the eye expression; and (b) how smile discrimination differs for human perceivers versus automated face analysis, depending on affective valence and morphological facial features. Human observers categorized faces as happy or non-happy, or rated their valence. Automated analysis (FACET software) computed seven expressions (including joy/happiness) and 20 facial action units (AUs). Physical properties (low-level image statistics and visual saliency) of the face stimuli were controlled. Results revealed, first, that some blended expressions (especially, with angry eyes) had lower discrimination thresholds (i.e., they were identified as "non-happy" at lower non-happy eye intensities) than others (especially, with neutral eyes). Second, discrimination sensitivity was better for human perceivers than for automated FACET analysis. As an additional finding, affective valence predicted human discrimination performance, whereas morphological AUs predicted FACET discrimination. FACET can be a valid tool for categorizing prototypical expressions, but is currently more limited than human observers for discrimination of blended expressions. Configural processing facilitates detection of in/congruence(s) across regions, and thus detection of non-genuine smiling faces (due to non-happy eyes). Copyright © 2018 Elsevier B.V.

Three Storm Surge Events during Late Holocene in Shelly Gravel Sediments of the most Southern Coast of Korean Peninsula

NASA Astrophysics Data System (ADS)

Yang, Dong Yoon

2015-04-01

Super Typhoon Haiyan which occurred in November, 2013 left as many as 5,200 people dead and destroyed towns across the Philippines. However, because of rapid climate change, we cannot disregard such a super typhoon strike probability in Korean Peninsula. If we can detect the frequency and periodicity of paleo-geohazards recorded in sediments, the extreme geohazards can be predicted and its damage can be somewhat mitigated. The geology, geochemistry and mineralogy of the island sediments ahead of Yeongjeon coast, Haenam-gun, the most southern part, Korean peninsula were investigated. Shells from the three shelly gravel layers were used for 14C age dating and cube samples were collected at 5-10cm intervals for measuring the magnetic susceptibility, grain size distribution and geochemical analyses at the study site. Granitic gneiss clasts of debris flow mixed with the weathered tuffaceous materials on the eroded face of tuff rock. The sediments of Pleistocene were also eroded almost horizontally and unconformably covered by late Holocene shelly gravel deposits characterized by some kind of shells and unsorted sub-rounded or rounded gravels to pebbles. The horizontal erosion face is 2.2m in elevation and the current erosion face of beach was observed at 1.2m in elevation. This indicates that the former erosion face would have been formed at higher sea level than those of latter one by the similar mechanism of current erosion in the study site. Three shelly gravel layers overlie the erosion face from 2.2m to 2.9m in elevation. The reflected water energy caused by stronger storm would have been needed for delivering gravels and cobbles to the erosion face. Three shell layers dated as 3200 yr BP, 1900 yr BP, and 1700 yr BP, respectively. Four sedimentary units, from unit 1 to 4 in ascending order, are distinguished on the basis of sedimentary textures, shell contents, grain size distribution and vertical color variations. The sand ratios in the grain size distribution pattern are likely to be related with high contents of gravels and cobbles in units 2 and 4. There have been more than three stronger storms to deliver the marine gravels and shells to the erosion face of 2.2m in elevation. Erosion process pronounced by basement erosion of tuffaceous rock, followed by sedimentation process of Pleistocene debris flows, subsequently Holocene erosion, and finally Holocene gravels and shells by reflected waves near beach. The sedimentation is not controlled by the influence of break water, but is affected by the reflected water from coastal zone.
