  1. Signifying Bodies

    DEFF Research Database (Denmark)

    of biosemiosis connect signifying bodies with their natural surroundings, cultural activities and subjective experiences. Health stretches all the way from the ecosocial surroundings, through the skin and into the self-organizing processes of every living cell. Signifying Bodies lays out a new approach to health...... and health care. Eschewing all forms of dualism, the authors emphasise the interdependency of how we act, think, feel and function. They advocate a relational turn in health care, in which bodies live and learn from suffering and care. In this view, health is inseparable from both living beings...

    African Journals Online (AJOL)

    Based on Michel Foucault's idea of the power/knowledge relationship reflecting a sense of cultural criticism of the modern world, this paper investigates the issue of madness as a signifier in Briefing for a Descent into Hell, challenging the status quo of culture from all aspects, socio-political, medical, historical perspectives.

  3. Revisiting the master-signifier, or, Mandela and repression

    Full Text Available The concept of the master-signifier has been subject to a variety of applications in Lacanian forms of political discourse theory and ideology critique. While there is much to be commended in literature of this sort, it often neglects salient issues pertaining to the role of master signifiers in the clinical domain of (individual psychical economy. The popularity of the concept of the master (or ‘empty’ signifier in political discourse analysis has thus proved a double-edged sword. On the one hand it demonstrates how crucial psychical processes are performed via the operations of the signifier, extending thus the Lacanian thesis that identification is as much the outcome of linguistic and symbolic as opposed to merely psychological processes. On the other, the use of the master signifier concept within the political realm to track discursive formations tends to distance the term from the dynamics of the unconscious and operation of repression. Accordingly, this paper revisits the master signifier concept, and does so within the socio-political domain, yet while paying particular attention to the functioning of unconscious processes of fantasy and repression. More specifically, it investigates how Nelson Mandela operates as a master signifier in contemporary South Africa, as a vital means of knitting together diverse elements of post-apartheid society, enabling the fantasy of the post-apartheid nation, and holding at bay a whole series of repressed and negated undercurrents.

    Full Text Available The present study joins the series of works aiming to bring up to date, within Romanian linguistics, the theories concerning (Romanian-Hungarian linguistic interferences manifested in bilingual communities and the research of lexical properties which have entered the Romanian written language either by the influence of the Hungarian dialects, spoken in different regions of the country, or by the translation of Hungarian texts into Romanian. The study will focus on Hungarian loanwords in old Romanian language which are discussed in terms of their changes in meaning. The inventory of the Hungarian loanwords’ meanings listed here was made based on a corpus of old Romanian texts, taking into account the material provided by various dictionaries with etymological concerns. As the few examples analysed in this study show, lexical meaning is impregnated with both intellect and emotional sensibility. The emotional universe, however, is rarely taken over along with the loanword. The emotional content is most often adapted, in its turn, to the sensitivity and spirituality of the speakers who borrowed the word.

    Recognizing suicidal communication from the distressful catharsis in a high-risk group with suicidal tendencies is essential for suicide prevention. This study analyzes whether suicidal communication can indicate the severity of suicidal intent. Various types of suicidal communication are defined, and their clinical significance is further explored. A comprehensive analysis of the psychological autopsy data of 200 victims of completed suicide, including their general socio-demographic status, suicidal communication methods, previous suicide attempts, mental disorders, and psychosocial situation. Our results showed that 39.5% of all the subjects were suicidal communicators, 23.0% had previously attempted suicide, and 14.0% left suicide notes; 32.4% of 142 subjects free of physical disease suffered from mental disorders. Suicidal communication included verbal communication, behavioral communication, and suicidal notes. Younger people with a higher level of education were more inclined to communicate their suicidal intent by leaving a suicide note. Suicide notes, but not previous suicide attempts or psychosocial situation, were significantly correlated with suicidal intent. Suicidal communicators showed higher depression scores than non-communicators. Those who suffered from mood disorders with higher levels of both depression and suicidal intent were more likely to expose their intent through behavioral communication. The present study provides strong evidence that suicidal communication can indicate the severity of suicidal intent. Current findings help interpret high-risk, self-destructive behavior and consequently provide the theoretical basis for a feasible suicide prevention program.

  12. Combining epidemiological and genetic networks signifies the importance of early treatment in HIV-1 transmission.

    Full Text Available Inferring disease transmission networks is important in epidemiology in order to understand and prevent the spread of infectious diseases. Reconstruction of the infection transmission networks requires insight into viral genome data as well as social interactions. For the HIV-1 epidemic, current research either uses genetic information of patients' virus to infer the past infection events or uses statistics of sexual interactions to model the network structure of viral spreading. Methods for a reliable reconstruction of HIV-1 transmission dynamics, taking into account both molecular and societal data are still lacking. The aim of this study is to combine information from both genetic and epidemiological scales to characterize and analyse a transmission network of the HIV-1 epidemic in central Italy.We introduce a novel filter-reduction method to build a network of HIV infected patients based on their social and treatment information. The network is then combined with a genetic network, to infer a hypothetical infection transmission network. We apply this method to a cohort study of HIV-1 infected patients in central Italy and find that patients who are highly connected in the network have longer untreated infection periods. We also find that the network structures for homosexual males and heterosexual populations are heterogeneous, consisting of a majority of 'peripheral nodes' that have only a few sexual interactions and a minority of 'hub nodes' that have many sexual interactions. Inferring HIV-1 transmission networks using this novel combined approach reveals remarkable correlations between high out-degree individuals and longer untreated infection periods. These findings signify the importance of early treatment and support the potential benefit of wide population screening, management of early diagnoses and anticipated antiretroviral treatment to prevent viral transmission and spread.

  14. Urban informality as a signifier: Performing urban reordering in suburban Rio de Janeiro.

    Müller, Frank I

    2017-07-01

    Urban informality is typically ascribed to the urban poor in cities of the Global South. Drawing on Judith Butler's concept of performativity and taking the case of Rio de Janeiro in the context of the 2016 Olympic Games, this article conceptualizes informality as a signifier and a procedural, relational category. Specifically, it shows how different class actors have employed the signifier informality (1) to legitimize the confinement of marginalized populations; (2) to justify the organized efforts of the upper middle class to protect their 'self-enclosed' gated communities; and (3) to warrant the formation of opposition and alliances between inhabitants, activists, and researchers on the edges of the urban order. This article offers new perspectives to better understand the relationship between informality and confinement by examining the active role that inhabitants of marginalized settlements assume in the Olympic City.

    Cloyes, Kristin Gates

    2007-09-01

    Increasingly, US prisoners diagnosed with mental illness are housed in control units, the most restrictive form of confinement in the US prison system. This situation has led to intense debate over the legal, ethical and clinical status of mental illness. This is a semiotic struggle with profound effects, yet most related work treats mental illness as a neutral, individual variable. Few analyses locate mental illness within a larger sociopolitical context. Fewer still focus on discursive practice. None critically analyze the accounts of control unit prisoners, who talk about extreme marginality and risk for victimization. This paper has two aims: (i) to develop a systematic method of analysis that accounts for signification as discourse-in-action; and (ii) to show how prisoners' signification of mental illness articulates agency through and against marginalizing discourse. Political discourse analysis demonstrates how control unit prisoners with psychiatric diagnoses signify mental illness, and articulate safer identifications in the process.

    Full Text Available Resumo: No século XX, o recuo da prática religiosa não fez desaparecer a religião das obras, que continuam marcadas por essa prática. Até mesmo as obras blasfematórias exprimem, em seu conteúdo e forma, uma certa cultura religiosa, assim como outros textos, de temática diferente, servindo de base para a legibilidade ideológica, expressividade ou poeticidade dos mesmos. Existem, nesses textos, significâncias e funções diversas que podem ser observadas através da forma como são tratadas as culturas relacionadas com as religiões muçulmanas e cristãs nas literaturas das sociedades modernas. Atualmente, é muito raro haver uma inspiração direta e principal da religião, a menos que seja blasfematória, o que procederia dessa nova tradição subversiva, situada, recentemente, dentro de critérios de modernidade. Entretanto, nas sociedades de modernidade recente, em que o espiritual é ainda primordial, como no Senegal, a fidelidade a Deus é, às vezes, objeto poético e sua poeticidade coloca-se como meio discursivo eficaz, pela sua dupla função, persuasiva e perlocutória.Palavras-chave: Literatura senegalesa; religião; cristianismo; islamismo.Résumé: Au XXe siècle, le recul de la pratique religieuse n’a pas entraîné l’effacement de la religion dans les oeuvres et celles-ci continuent à en être marquées.

    Tip-of-the-tongue experiences (TOTs), in which a name is known but cannot be immediately retrieved from memory, can be a cause of concern if these experiences are viewed as a sign of memory decline. The current study was conducted to investigate the relation between age and TOT frequency, and the influence of episodic memory, which is the type of memory most often assessed to detect memory problems, on that relation. In a sample of adults, increased age was found to be associated with more TOTs across different types of materials, and additional analyses suggested that these relations between age and TOT frequency were not attributable to the use of different response criteria or to different amounts of knowledge. Because statistical control of a measure of episodic memory had little effect on the relation between age and TOT frequency, age-related increases in TOTs and age-related decreases in episodic memory appear to be at least partially independent phenomena.

  1. Probing the potential of mucus permeability to signify preterm birth risk.

    2017-09-04

    Preterm birth is the leading cause of neonatal mortality, and is frequently associated with intra-amniotic infection hypothesized to arise from bacterial ascension across a dysfunctional cervical mucus plug. To study this dysfunction, we assessed the permeability of cervical mucus from non-pregnant ovulating (n = 20) and high- (n = 9) and low-risk (n = 16) pregnant women to probes of varying sizes and surface chemistries. We found that the motion of negatively charged, carboxylated microspheres in mucus from pregnant patients was significantly restricted compared to ovulating patients, but not significantly different between high- and low-risk pregnant women. In contrast, charged peptide probes small enough to avoid steric interactions, but sensitive to the biochemical modifications of mucus components exhibited significantly different transport profiles through mucus from high- and low-risk patients. Thus, although both microstructural rearrangements of the components of mucus as well as biochemical modifications to their adhesiveness may alter the overall permeability of the cervical mucus plug, our findings suggest that the latter mechanism plays a dominant role in the impairment of the function of this barrier during preterm birth. We expect that these probes may be readily adapted to study the mechanisms underlying disease progression on all mucosal epithelia, including those in the mouth, lungs, and gut.

    2016-04-01

    The southern Levantine coastline is exposed to a variety of potential tsunami-generating sources, including far field influences such as large earthquakes and volcanic eruptions as well as near field offshore landslides along the continental slope, where slumping features are present throughout the area. Not only does this coast boast a long history of continuous occupation but also today large cities (e.g. Tel Aviv, Ashdod, Ashkelon, and Gaza) and related critical infrastructure such as ports, power plants, chemical industries, roads, etc. are located along this corridor. In addition, further to the south, the Gaza Strip has one of the highest population densities in the world and is dependent on external assistance for many basic needs, goods and infrastructure. Newly obtained sediment cores from the shallow shelf offshore Ashkelon (~12 km north of Gaza City) exhibit several events that can be linked to historical records. These cores can be subdivided in two general horizon types that show relative changes to one another across different proxies. The continuous input of Nile-delta sands results in a homogenous and stable 'background' sediment represented by well sorted, finer sands, few inclusions, lower proportions of A. parkinsoniana relative to fossil tests, and very few yellow-stained and blackened specimens. Contrasting these normal marine condition deposits are high energy tsunamigenic deposits characterized by poor sorting, with inclusions of a range of whole, articulated, and fragmented shells, wood, charcoal, and sub-angular to rounded pebbles. Newly mapped and quantified offshore bathymetric evidence for landslides and slumping motion has identified features that are large enough to generate tsunamis that would affect the study area. These were modeled as possible sources and compared to different far field events. Some of those tsunamigenic horizons could be assigned to specific events ranging between the youngest at 1202AD to the oldest prehistoric

  6. What Does 'Unpaid Consultant' Signify? A Survey of Euphemistic Language in Conflict of Interest Declarations.

    Menkes, David B; Masters, Jill D; Bröring, Angela; Blum, Alan

    2018-02-01

    Inadequate competing interest declarations present interpretive challenges for editors, reviewers, and readers. We systematically studied a common euphemism, 'unpaid consultant,' to determine its occurrence in declarations and its association with vested interests, authors, and journals. We used Google Scholar, a search engine that routinely includes disclosures, to identify 1164 occurrences and 787 unique biomedical journal publications between 1994 and 2014 that included one or more authors declaring themselves as an "unpaid consultant." Changes over time were reckoned with absolute and relative yearly rates, the latter normalized by overall biomedical publication volumes. We further analyzed declarations according to author, consultancy recipient, and journal. We demonstrate increases in the use of "unpaid consultant" since 2004 and show that such uninformative declarations are overwhelmingly (801/865, 92.6%) associated with for-profit companies and other vested interests, most notably in the pharmaceutical, device, and biotech industries. Disclosing 'unpaid' relationships with for-profit companies typically signals but does not explain competing interests. Our findings challenge editors to respond to the increasing use of language that may conceal rather than illuminate conflicts of interest.

    Tumour-infiltrating lymphocytes (TILs) signify immune response to tumour in a variety of cancers including breast cancer. However, earlier studies examining the clinical significance of TILs in breast cancers have generated mixed results. There are only a few that address the relationship between TILs and clinical outcomes in triple-negative breast cancers (TNBC). The aim of this study is to evaluate the clinical significance of TILs that express CD4 + and CD8 + , in TNBC. Immunohistochemical staining of CD4 and CD8 was performed on tissue microarrays of 164 cases of TNBC. TILs were counted separately as intratumoral when within the cancer cell nests (iTILs) and as stromal when within cancer stroma (sTILs). High CD8 + iTILs and sTILs, and CD4 + iTILs correlated with histologic grade. On Kaplan-Meier analysis, a significantly better survival rate was observed in high CD8 + iTIL (disease-free survival, DFS: P = 0.004, overall survival, OS: P = 0.02) and both high CD4 + iTILs (DFS: P = 0.025, OS: P = 0.023) and sTILs (DFS: P = 0.01, OS: P = 0.002). In multivariate analysis, CD8 + iTILs (DFS: P = 0.0095), CD4 + sTILs (DFS: P = 0.0084; OS: P = 0.0118), and CD4 (high) CD8 (high) CD8 iTILs (DFS: P = 0.0121; OS: P = 0.0329) and sTILs (DFS: P = 0.0295) showed significantly better survival outcomes. These results suggest that high levels of both CD8 + iTILs and CD4 + sTILs as well as CD4 (high) CD8 (high) iTILs and sTILs are independent prognostic factors in TNBC.

    The demand for clean water in South Tangerang, Indonesia, is very high. At present, this demand is mostly met by groundwater that is much influenced by climate variability, land cover change, and human activities. The local company on water services (PDAM) provides clean water services for only about 9% of the population. The climate risk assessment conducted by South Tangerang Government in 2016 indicates that several areas are potentially exposed to a high risk of climate change. Survey and in-depth interview with communities and sectoral officers suggest that a risk to clean water supply in this city is increasing. This study aims to assess climate potential risks on clean water supply based on the 2016 study. We adopted the method of that study by modifying some of the vulnerability indicators that can represent clean water access and supply. The results of the study demonstrate that many wards in South Tangerang would be exposed to high climate risks of clean water supply. By 2021, about 54% of wards would be exposed from high to the very very high risk of clean water supply. These results signify the tangible need of adaptation actions, to prevent the worsening impacts of climate on clean water supply.

    Emerging data indicate that gut-derived endotoxin (metabolic endotoxemia) may contribute to low-grade systemic inflammation in insulin-resistant states. Specific gut bacteria seem to serve as lipopolysaccharide (LPS) sources and several reports claim a role for increased intestinal permeability in the genesis of metabolic disorders. Therefore, we investigated the serum levels of LPS and zonulin (ZO-1, a marker of gut permeability) along with systemic levels of tumor necrosis factor-α (TNF-α) and Interleukin-6 (IL-6) in patients with type 2 diabetes mellitus (T2DM) compared to control subjects. Study subjects were recruited from the Chennai Urban Rural Epidemiology Study [CURES], Chennai, India. Study group (n = 45 each) comprised of a) subjects with normal glucose tolerance (NGT) and (b) patients with T2DM. LPS, ZO-1, TNF-α, and IL-6 levels were measured by ELISA. Serum levels of LPS [p < 0.05], LPS activity [p < 0.001], ZO-1 [p < 0.001], TNFα [p < 0.001], and IL-6 [p < 0.001] were significantly increased in patients with T2DM compared to control subjects. Pearson correlation analysis revealed that LPS activity was significantly and positively correlated with ZO-1, fasting plasma glucose, 2 h post glucose, HbA1c, serum triglycerides, TNF-α, IL-6, and negatively correlated with HDL cholesterol. Regression analysis showed that increased LPS levels were significantly associated with type 2 diabetes [odds ratio (OR) 13.43, 95 % CI 1.998-18.9; p = 0.003]. In Asian Indians who are considered highly insulin resistant, the circulatory LPS levels, LPS activity, and ZO-1 were significantly increased in patients with type 2 diabetes and showed positive correlation with inflammatory markers and poor glycemic/lipid control.

    Full Text Available Ao tratar da pesquisa empreendida por J. Conrad sobre a esquizofrenia incipiente, esse artigo demonstra a atualidade desse estudo: destaca-se a abordagem estrutural do desencadeamento psicótico ali inaugurada antes mesmo de Lacan estender a perspectiva estruturalista à fenomenologia da clínica. Enfatiza-se a estratégia utilizada por Conrad, que propõe pensar o desencadeamento psicótico nos termos da estrutura formal da percepção delirante. Demonstra-se em que sentido a perspectiva de Conrad resgata a inteligibilidade do fenômeno psicótico, opondo-se à estratégia da fenomenologia compreensiva fundada por Jaspers, a qual relegava ao plano somático da causalidade física os fenômenos mentais destituídos de compreensão.By dealing with Conrad's research on incipient schizophrenia, this article demonstrates the actual relevance of the study: it highlights the structural approach of psychotic crisis inaugurated by him, even before Lacan expands the structuralist perspective to the clinic's phenomenology. The author emphasizes the strategy employed by Conrad, who proposes to discuss the origins of psychotic crisis in terms of the formal structure of the delirious perception. He shows therefore the way Conrad's perspective is able to recover the intelligibility of the psychotic phenomenon, in opposition to the strategy of comprehensive phenomenology founded by Jaspers, which relegates to the somatic plan of physical causality the mental occurrences deprived of comprehension.

    Pollution of groundwater is a primary issue because aquifers are susceptible to contamination from land use and anthropogenic impacts. Groundwater susceptibility is intrinsic and specific. Intrinsic vulnerability refers to an aquifer that is susceptible to pollution and to the geological and hydrogeological features. Vulnerability assessment is an essential step in assessing groundwater contamination. This approach provides a visual analysis for helping planners and decision makers to achieve the sustainable management of water resources. Comparative studies are applying different methodologies to result in the basic evaluation of the groundwater vulnerability. Based on the comparison of methods, there are several advantages and disadvantages. SI can be overlaid on DRASTIC and Pesticide DRASTIC to extract the divergence in sensitivity. DRASTIC identifies low susceptibility and underestimates the pollution risk while Pesticide DRASTIC and SI represents better risk and is recommended for the future. SINTACS method generates very high vulnerability zones with surface waters and aquifer interactions. GOD method could be adequate for vulnerability mapping in karstified carbonate aquifers at small-moderate scales, and EPIK method can be used for large scale. GOD method is suitable for designing large area such as land management while DRASTIC has good accuracy and more real use in geoenvironmental detailed studies.

    Conceição Maria de Oliveira

    Full Text Available Abstract Objectives: assess the implementation of child mortality surveillance in Recife/PE. Methods: an analytical evaluative study was conducted on its implementation. It was a single-case study that correlated degree of implementation with the of the result indicators surveillance. A logic model on this strategy and a matrix of indicators and judgments according to model components were drawn up. The degree of implementation was obtained from structure and process indicators and this was then correlated with result indicators, in a deductive approach based on intervention theory. Results: the structure approach presented superior results to the process in all evaluated components. This strategy was considered to have been partially implemented (75. 7%, however, the components of 'identification of deaths' (85.7%, 'epidemiological research' (88.1% and 'referral of proposals for promotion and health care and correction of official statistics' (95.8% were classified implemented. Regarding the relation of the degree of implantation of the surveillance and its results with the logical model, only one of the 17 indicators was considered inconsistent. Conclusions: this strategy was considered to have been partially implemented. The model of child mortality surveillance and its assessment were shown to be adequate for signaling the consistency of the interrelations between the activities proposed and the effects expected, and would be reproducible within other scenarios.

    2014-07-01

    Full Text Available Introduction & Objective: The Modified Modified Ashworth Scale (MMAS is a clinical meas-ure that has been recently developed for the assessment of muscle spasticity. There is a dearth of research on the validity of the MMAS. The aim of the present study was to investi-gate the relationship between the MMAS and the biomechanical measure of work-velocity slope in assessing knee extensor muscle spasticity in patients with hemiparesia. Materials & Methods: Fourteen patients with post-stroke hemiparesia were included in this cross sectional study. Knee extensor spasticity was assessed with MMAS. An isokinetic dy-namometer was used to impose knee passive flexion with the angular velocity of 10, 30, 60, and 90 °/Sec to measure Torque-angle data. Work (Joule was calculated at each velocity to determine the slope of the work-velocity curves as the biomechanical measure of muscle spasticity. Results: The mean work decreased as the velocity increased but was not statistically signifi-cant (P = 0.07. The mean slope was – 0.35 [J /(°/Sec]. There was no significant correlation between the MMAS and the work-velocity slope (r =0.31, P = 0.28. Conclusion: There was no significant relationship between the MMAS and the biomechanical measure of work-velocity slope. Further studies with larger sample size are suggested.

    This report documents some calculations performed to assess the Hydrogen Mixing Studies (HMS) code. Results are presented first for some analytical test problems, including laminar flow and mass diffusion. The von Karman vortex street problem and the Sandia FLAME Facility and Heiss Dampf Reaktor (HDR) containment facility test problems are then discussed. For the analytical problems, the code gave results that agree exceptionally well with the analytical solutions. Calculations for the von Karman vortex street problem were performed at selected Reynolds numbers for several obstacle types. The computed flow patterns agree well with experimental observations-specifically the occurrence of a vortex street (double row of vortices) above a critical Reynolds number. Calculations for the von Karman vortex street problem were performed at selected Reynolds numbers for several obstacle types. The computed flow patterns agree well with experimental observations-specifically the occurrence of a vortex street (double row of vortices) above a critical Reynolds number. The last assessment problem involves modeling the experiment T31.5. The experiment was carried out in the HDR containment building, which is a large, multi-compartment facility (11 300 m 3 free volume in 72 compartments). In the experiment, a steam-water mixture was first injected into the containment to simulate a large-break blowdown of a pressure vessel, and then superheated steam was injected that was followed by a release of helium-hydrogen light gas. The calculated results (pressure, temperature, and gas concentrations) agree reasonably well with the experimental data

    This Advanced Fuel Cycle Initiative (AFCI) study has developed new analysis methods to examine old and new technology options toward the goal of improving fuel cycle systems. We have integrated participants and information from AFCI Systems Analysis, Transmutation Fuels, Separations, and Waste Form Campaigns in the Systems Losses and Assessment Trade Study. The initial objectives of this study were to (1) increase understanding of system interdependencies and thereby identify system trade-offs that may yield important insights, (2) define impacts of separations product purity on fuel manufacture and transmutation reactivity, (3) define impacts from transuranic (TRU) losses to waste, (4) identify the interrelationships involved in fuels and separations technology performance, and (5) identify system configuration adjustments with the greatest potential for influencing system losses. While bounding and analyzing this initial problem, we also identified significantly higher-level programmatic drivers with broad implications to the current fuel cycle research charter and the general issue of a DOE complex wide need for a comprehensive and integrated nuclear material management as addressed by the new DOE Order 410.2 titled 'Management of Nuclear Materials'. The initial modeling effort developed in this study for a much smaller subset of material (i.e., commercial fuel) and a selected transmutation scheme (i.e., fast reactor recycling) is a necessary first step towards examining a broader set of nuclear material management options, dispositioning strategies and integrated waste management options including potential areas of research leverage. The primary outcome from this initial study has been an enhanced integration among Campaigns and associated insights and analysis methods. Opportunities for improved understanding between the groups abound. The above lanthanide-actinide example highlights the importance of evaluating options via integration across the Campaigns

    The undergraduate curriculum in psychology profoundly reflects and shapes the discipline. Yet, reliable information on the undergraduate psychology curriculum has been difficult to acquire due to insufficient research carried out on unrepresentative program samples with disparate methods. In 2014, APA launched the first systematic effort in a decade to gather national data on the psychology major and program outcomes. We surveyed a stratified random sample of department chairs/coordinators of accredited colleges and universities in the United States that offer undergraduate courses and programs in psychology. A total of 439 undergraduate psychology programs (45.2%) completed the survey. This article summarizes, for both associate and baccalaureate programs, the results of the Undergraduate Study in Psychology. Current practices concerning the introductory course, the courses offered, core requirements, the psychology minor, and tracks/concentrations are presented. The frequency of formal program reviews and program-level assessment methods are also addressed. By extending prior research on the undergraduate curriculum, we chronicle longitudinal changes in the psychology major over the past 20 years. (c) 2016 APA, all rights reserved).

    This article aims to assess the potential environmental impact of an electrical grinder during its life cycle. The Life Cycle Inventory Analysis was conducted based on the Simplified Life Cycle Assessment (SLCA) Drivers that calculated from the Valuation of Social Cost and Simplified Life Cycle Assessment Model (VSSM). The detailed results for LCI can be found under Appendix II. The Life Cycle Impact Assessment was performed based on Eco-indicator 99 method. The analysis results indicated that the major contributor to the environmental impact as it accounts for over 60% overall SLCA output. In which, 60% of the emission resulted from the logistic required for the maintenance activities. This was measured by conducting the hotspot analysis. After performing sensitivity analysis, it is evidenced that changing fuel type results in significant decrease environmental footprint. The environmental benefit can also be seen from the negative output values of the recycling activities. By conducting Life Cycle Assessment analysis, the potential environmental impact of the electrical grinder was investigated.

    2006-01-01

    In early 2003, Bruce Power restarted two of its previously laid up units in the Bruce A generating station, Units 3 and 4. However, due to challenges relating to the availability of personnel with active Shift Manager licenses, an alternate shift structure was proposed to ensure the safe operation of the station. This alternate structure resulted in a redistribution of responsibility, and a need to assess the resulting changes in workload. Atomic Energy of Canada Limited was contracted to perform a workload assessment based on the new shift structure, and to provide recommendations, if necessary, to ensure Shift Managers had sufficient resources available to perform their required duties. This paper discusses the performance of that assessment, and lessons learned as a result of the work performed during the Restart project. (authors)

    Systemic sclerosis (SSc)-related digital ulcers (DU) cause significant pain and disability and are often a primary endpoint in clinical trials. However, their pathophysiology has been little studied. The objectives of this prospective study were to determine whether laser Doppler imaging (LDI) and thermography can identify ischaemic components in both fingertip and extensor surface DU and assess ulcer healing. Patients prospectively reported new DU over a year. Patients' DU underwent imaging until the ulcer had healed. Ischaemia was defined as lower blood flow or skin temperature (and inflammation as higher) within the ulcer, compared to a non-affected site. 53 ulcers (19 fingertip, 18 extensor, 16 'other' sites) in 17 patients were imaged (53 with LDI, 52 with thermography). For LDI data 32 (60%) ulcers were ischaemic; median perfusion ulcer/unaffected area; 0.79 (range 0.11-2.9). For thermography data 35 (66%) were ischaemic; 0.98 (0.89 to 1.1). Inflammation in the surrounding area was identified for all ulcers by LDI but not thermography. In the 36 ulcers with repeat imaging, LDI showed trends (with healing) towards increased ulcer perfusion (p=0.23) and decreased hyperaemia in adjacent areas (p=0.59). Skin temperature at the ulcer site showed no significant change (p=0.13) but adjacent area showed decreased temperature (p=0.04 signifying decreased blood flow). LDI and thermography are sufficiently sensitive to measure ischaemia in both fingertip and extensor ulcers. LDI was better suited to monitoring change in perfusion with healing (due to higher imaging resolution, or vascular changes occurring in more superficial skin layers).

  15. Cooperative Student Assessment Method: an Evaluation Study

    2006-06-01

    Full Text Available Training through the Internet poses a series of technical problems and pedagogical issues. Traditional training is not indiscriminate but takes on different forms according to the needs of the subject being trained and the context where such training occurs. In order to make the systems adaptable in this way, a model of the student’s characteristics - the student model - has to be set up, maintained and updated. However, there are many difficulties involved in obtaining sufficient information to create an accurate student model. One way to solve this problem is to involve students in the student modeling process, stimulating them to provide the necessary information by means of a dialog in which the student and system build the student model according to a collaborative process. The present work describes a cooperative student modeling method (Cooperative Student Assessment - CSA which builds a joint system-student assessment of student’s activities on the basis of the student’s self-assessment ability estimation and a prototype system for children, addressing the learning of fractions, in which CSA is implemented. The article also reports the result of an experimentation carried out with learners attending primary school aiming at evaluating the effectiveness of involving students in the assessment process by comparing two versions of the same system: one using cooperative student modeling and the other the traditional overlay model.

  16. Assessing biofuel crop invasiveness: a case study.

    Directory of Open Access Journals (Sweden)

    Christopher Evan Buddenhagen

    Full Text Available BACKGROUND: There is widespread interest in biofuel crops as a solution to the world's energy needs, particularly in light of concerns over greenhouse-gas emissions. Despite reservations about their adverse environmental impacts, no attempt has been made to quantify actual, relative or potential invasiveness of terrestrial biofuel crops at an appropriate regional or international scale, and their planting continues to be largely unregulated. METHODOLOGY/PRINCIPAL FINDINGS: Using a widely accepted weed risk assessment system, we analyzed a comprehensive list of regionally suitable biofuel crops to show that seventy percent have a high risk of becoming invasive versus one-quarter of non-biofuel plant species and are two to four times more likely to establish wild populations locally or be invasive in Hawaii or in other locations with a similar climate. CONCLUSIONS/SIGNIFICANCE: Because of climatic and ecological similarities, predictions of biofuel crop invasiveness in Hawaii are applicable to other vulnerable island and subtropical ecosystems worldwide. We demonstrate the utility of an accessible and scientifically proven risk assessment protocol that allows users to predict if introduced species will become invasive in their region of interest. Other evidence supports the contention that propagule pressure created by extensive plantings will exacerbate invasions, a scenario expected with large-scale biofuel crop cultivation. Proactive measures, such as risk assessments, should be employed to predict invasion risks, which could then be mitigated via implementation of appropriate planting policies and adoption of the "polluter-pays" principle.

    Culham Center for Fusion Energy (CCFE) in UK has been contracted to undertake a second Deuterium-Tritium Experiment (DTE2) using Join European Torus (JET) in 2017, in support of technical developments for the ITER project. In order to manage risks of delay or early project termination CCFE has adopted a risk based inspection (RBI) process to identify the systems which could influence the successful delivery of DTE2 and in turn to identify by a basic risk assessment process those systems or components which require mitigating action in order to minimize risk. In this context, the primary purpose of the RBI is to address issues of reliability and satisfactory functionality in a similar way to that which a power plant operator would take to address its commercial risks in the event of loss of generating capacity. The objective of this presentation is describe the activities developed for Idom to deliver the survey, interviews and risk assessment of different systems of JET with the aim to identify the critical components and system that could affect the operation of JET during the DTE2 experiment.

    Determination of lower limb alignment is a prerequisite for successful orthopedic surgical treatment. Traditional methods include the electrocautery cord, alignment rod, or axis board which rely solely on C-arm fluoroscopy navigation and are radiation intensive. To assess a new augmented reality technology in determining lower limb alignment. A camera-augmented mobile C-arm (CamC) technology was used to create a panorama image consisting of hip, knee, and ankle X-rays. Twenty-five human cadaver legs were used for validation with random varus or valgus deformations. Five clinicians performed experiments that consisted in achieving acceptable mechanical axis deviation. The applicability of the CamC technology was assessed with direct comparison to ground-truth CT. A t test, Pearson's correlation, and ANOVA were used to determine statistical significance. The value of Pearson's correlation coefficient R was 0.979 which demonstrates a strong positive correlation between the CamC and ground-truth CT data. The analysis of variance produced a p value equal to 0.911 signifying that clinician expertise differences were not significant with regard to the type of system used to assess mechanical axis deviation. All described measurements demonstrated valid measurement of lower limb alignment. With minimal effort, clinicians required only 3 X-ray image acquisitions using the augmented reality technology to achieve reliable mechanical axis deviation.

    A growing number of sources of radioactivity from human activities are found in the marine environment. They are known to include global nuclear fallout following atmospheric weapons tests, the Chernobyl accident, discharges of radionuclides from nuclear installations, past dumping of radioactive wastes, nuclear submarine accidents, contributions from nuclear testing sites, loss of radioactive sources, and the burn-up of satellites using radioisotopes as power sources. Overall, the world's marine environment contains radionuclides that differ from one region to another. Differences are due to dynamic marine environmental processes and the particular source of radionuclides in a region. Scientific assessments of marine radioactivity, therefore, require knowledge of both the source terms and oceanic processes. Radioactivity now is deposited unevenly over the world's oceans. Global fallout is known to be mainly due to nuclear weapon tests carried out in the 1960s. On the other hand, discharges from nuclear fuel reprocessing plants or past dumping of liquid and solid radioactive wastes generally are confined to more localized areas. Even so, soluble radionuclides have been transported over long distances by prevailing ocean currents. To estimate radionuclide inputs from local sources, scientists need to better understand the distribution of radionuclides throughout the world's oceans and seas. The understanding is important for analysing the results from scientific investigations of localized areas, such as part dumping sites, which then can be reviewed more thoroughly. As a contribution to fuller understanding of the marine environment, the IAEA's Marine Environment Laboratory (MEL) started a five-year project in 1996 entitled ''Research on Worldwide Marine Radioactivity (MARS)''. The work is supported by Japan's Science and Technology Agency (STA). This article briefly review this project, and describes related research activities and scientific investigations of MEL

  4. Methodologic assessment of radiation epidemiology studies

    International Nuclear Information System (INIS)

    Beebe, G.W.

    1983-01-01

    Epidemiologic studies of the late effects of ionizing radiation have utilized the entire spectrum of situations in which man has been exposed. These studies have provided insights into the dependence of human effects upon not only dose to target tissues but also other dimensions of exposure, host characteristics, and time following exposure. Over the past three decades studies have progressed from the mere identification of effects to their measurement. Because investigators of human effects have no control over the exposure situation, validity must be sought in the consistency of findings among independent studies and with accepted biologic principles. Because exposure may be confounded with factors that are hidden from view, bias may enter into any study of human exposure. Avoidance of bias and attainment of sufficient power to detect relationships that are real are methodologic challenges. Many methodologic issues, e.g., those associated with the definition and measurement of specific end-points, or with the selection of appropriate controls, permeate epidemiologic work in all fields. Others, especially those concerned with the measurement of exposure, the patterning of events in time after exposure, and the prediction of events beyond the scope of existing observations give radiation epidemiology its distinctive character

    A comparison of two studies conducted ten years apart on energy accidents provides important insights into methodological issues and policy implications. Recommendations for further improvements in energy accident studies are developed including accounting for differences between average and incremental accident damages, testing for appropriate levels of aggregation of accidents, making references and databases publicly available, more precisely defining and reporting different types of economic damages, accounting for involuntary and voluntary risks, reporting normalized damages, raising broader public policy and planning implications and updating existing accident databases.

    Full Text Available Abstract Background The quantification of uncertainty and variability is a key component of quantitative risk analysis. Recent advances in Bayesian statistics make it ideal for integrating multiple sources of information, of different types and quality, and providing a realistic estimate of the combined uncertainty in the final risk estimates. Methods We present two case studies related to foodborne microbial risks. In the first, we combine models to describe the sequence of events resulting in illness from consumption of milk contaminated with VTEC O157. We used Monte Carlo simulation to propagate uncertainty in some of the inputs to computer models describing the farm and pasteurisation process. Resulting simulated contamination levels were then assigned to consumption events from a dietary survey. Finally we accounted for uncertainty in the dose-response relationship and uncertainty due to limited incidence data to derive uncertainty about yearly incidences of illness in young children. Options for altering the risk were considered by running the model with different hypothetical policy-driven exposure scenarios. In the second case study we illustrate an efficient Bayesian sensitivity analysis for identifying the most important parameters of a complex computer code that simulated VTEC O157 prevalence within a managed dairy herd. This was carried out in 2 stages, first to screen out the unimportant inputs, then to perform a more detailed analysis on the remaining inputs. The method works by building a Bayesian statistical approximation to the computer code using a number of known code input/output pairs (training runs. Results We estimated that the expected total number of children aged 1.5-4.5 who become ill due to VTEC O157 in milk is 8.6 per year, with 95% uncertainty interval (0,11.5. The most extreme policy we considered was banning on-farm pasteurisation of milk, which reduced the estimate to 6.4 with 95% interval (0,11. In the second

    To assess brush sign (BS) on susceptibility-weighted imaging (SWI) in prediction of hemorrhagic transformation (HT) in patients with acute ischemic stroke (AIS) after intravenous thrombolysis(IVT). Patients with acute cerebral ischemic stroke, who had major cerebral artery occlusion (internal carotid artery, middle cerebral artery M1 and M2), treated with intravenous recombinant tissue plasminogen activator (rt-PA) from August 2009 to October 2014 in the Second Affiliated Hospital, Zhejiang University School of Medicine, were enrolled in the study. All patients underwent SWI scanning. The asymmetry index (AI) was defined as the difference of intensity between ischemic and normal hemispheres on the SWI phase map; according to AI values patients were divided into 3 groups: BS=0(n=9), BS=1 (n=39) and BS=2 (n=18). The relationships between BS and HT and the clinical outcome among the 3 groups were analyzed. Sixty-six patients aged 68 ± 13 years were included in the study, including 44 males (67%) and 22 females (33%), and 44 (67%) with acute ischemic stroke. The mean pre-treatment National Institutes of Health Stroke Scale (NIHSS) score was 13 (6-17), and the onset to needle time was (252 ± 88) min. Twenty-six (39.4%) patients had HT, including 18 cases (27.3%) with HI and 8 cases (12.1%) with PH; BS was observed more frequently in HT group than non-HT group. Binary logistic regression analysis showed that BS was independently associated with HT of patients with acute ischemic stroke following IVT (OR=2.589, 95% CI: 1.080-6.210, P=0.033). In those without reperfusion after IVT, patients with higher BS grade had higher HT rate (P=0.023). Brush sign on SWI can be used for predicting hemorrhagic transformation after intravenous thrombolysis in patients with acute ischemic stroke.

    The purpose of this study was to ascertain how well different wound assessment tools meet the needs of nurses in carrying out general wound assessment and whether current tools are fit for purpose. The methodology employed was evaluation research. In order to conduct the evaluation, a literature review was undertaken to identify the criteria of an optimal wound assessment tool which would meet nurses' needs. Several freely available wound assessment tools were selected based on predetermined inclusion and exclusion criteria and an audit tool was developed to evaluate the selected tools based on how well they met the criteria of the optimal wound assessment tool. The results provide a measure of how well the selected wound assessment tools meet the criteria of the optimal wound assessment tool. No tool was identified which fulfilled all the criteria, but two (the Applied Wound Management tool and the National Wound Assessment Form) met the most criteria of the optimal tool and were therefore considered to best meet nurses' needs in wound assessment. The study provides a mechanism for the appraisal of wound assessment tools using a set of optimal criteria which could aid practitioners in their search for the best wound assessment tool. © 2013 The Authors.

    2016-12-01

    Full Text Available Shifting from teacher-centred to student-centred practices requires teachers to understand strategies to interact with students in science classes. Formative assessment strategies are very critical component of classroom interaction where teachers obtain information about student learning wherever possible. Traditionally, however, teachers ask questions and evaluate student responses but without investigating student contributions to the classroom interaction. This qualitative study aimed at developing teachers’ knowledge of formative assessment strategies when teaching science-based inquiry in Saudi Arabia. 12 teachers were observed when teaching science and details of one teachers’ practices of formative assessment is presented in this study. Formative assessment framework that describes assessment conversations is used and modified to observe teachers’ assessment practices. Assessment conversation consists of four-step cycles, where the teacher elicits information from students through questioning, the student responds, the teacher recognizes the student’s response, and then uses the information to develop further inquiry. Findings indicate that teachers ask questions and receive responses but rarely allow students to share their own ideas or discuss their own thinking. The study underlines the importance of integrating formative assessment strategies during scientific inquiry teaching for professional development as a way to increase student participation and allow opportunities for students’ inquiry in science classes.

    The results of early animal studies of engineered nanomaterials (ENMs) and air pollution epidemiology suggest that it is important to assess the health of ENM workers. Initial epidemiological studies of workers’ exposure to ENMs (<100 nm) are reviewed and characterized for their study designs, findings, and limitations. Of the 15 studies, 11 were cross-sectional, 4 were longitudinal (1 was both cross-sectional and longitudinal in design), and 1 was a descriptive pilot study. Generally, the studies used biologic markers as the dependent variables. All 11 cross-sectional studies showed a positive relationship between various biomarkers and ENM exposures. Three of the four longitudinal studies showed a negative relationship; the fourth showed positive findings after a 1-year follow-up. Each study considered exposure to ENMs as the independent variable. Exposure was assessed by mass concentration in 10 studies and by particle count in six studies. Six of them assessed both mass and particle concentrations. Some of the studies had limited exposure data because of inadequate exposure assessment. Generally, exposure levels were not very high in comparison to those in human inhalation chamber studies, but there were some exceptions. Most studies involved a small sample size, from 2 to 258 exposed workers. These studies represent the first wave of epidemiological studies of ENM workers. They are limited by small numbers of participants, inconsistent (and in some cases inadequate) exposure assessments, generally low exposures, and short intervals between exposure and effect. Still, these studies are a foundation for future work; they provide insight into where ENM workers are experiencing potentially adverse effects that might be related to ENM exposures

    2014-07-01

    Full Text Available This article includes a study that examines how formative assessment in dance education is constituted in three Swedish upper secondary schools. The starting-point for the study is life-world phenomenology.  A phenomenological way of thinking entails that the human being is intersubjective, linked with and within the world and that learning requires the bodily subject´s active experience. To turn towards the things themselves and to be open and adherent to things in the world is a basic rule and the starting point for research within phenomenology. This study is based on empirical material from observations of the phenomenon formative assessment in dance. Spiegelberg´s philosophical method was used as a base for phenomenological analysis. The analysis results in three themes: modes of communication, dance-related knowledge and function of formative assessment. Formative assessment was observed in the study to commonly involve teachers´ verbal communication and visualisation. The assessment practice is a continuous activity and very rarely involves any kind of self-assessment or tests. The results were discussed and related to a life-world phenomenological view of learning and earlier research.

  12. To study the role of dynamic magnetic resonance imaging in assessing the femoral head vascularity in intracapsular femoral neck fractures

    2010-01-01

    Intracapsular femoral neck fractures remain unsolved fractures even after improvement in techniques of diagnosis and internal fixation. Individuals who sustain displaced femoral neck fractures are at high risk of developing avascular necrosis and non-union. Although several methods for predicting the viability of femoral head have been reported, they are not effective or widely used because of unreliability, potential complications and technical difficulties. Dynamic MRI was introduced in the recent past as a simple, non-invasive technique to predict the femoral head viability after the femoral neck fractures. In this study role of dynamic MRI was studied in 30 patients with 31 intracapsular femoral neck fractures. Fractures were divided in to three types according to dynamic curve patterns on MRI evaluation and were followed up for 6 months to 2 years to observe the final outcome. Sensitivity, Specificity and the Accuracy of dynamic MRI in predicting vascularity after femoral neck fracture are 87%, 88% and 87%, respectively. Type A or Type B curve pattern is a positive factor to successful osteosynthesis with p value <0.0001 (Chi-square test). This is a statistically significant value. From this finding it can be suggested that the reliability of dynamic curves A and B in predicting maintained vascularity of femoral head is high. This investigation can be used to predict the vascularity of femoral head after intracapsular femoral neck fractures. There was a good correlation between the outcomes of fractures and dynamic MRI curves done within 48 h of injury. This signifies the role of dynamic MRI in predicting the vascularity of femoral head as early as 48 h. A treatment algorithm can be suggested on the basis of dynamic MRI curves. The fractures with Type C dynamic curve should be considered as fractures with poor vascularity of femoral head and measures to enhance the vascularity of femoral head along with rigid internal fixation should be undertaken to promote

Exploring experiential assessment will allow identification of commonly used methods and facilitate the development of best practices of assessment in the context of experiential learning (EL at an institutional level. The origins of EL are found in the work of Dewey (1938, later modified by Kolb and Fry (1975. Experiential methods include: experiential education, service learning problem-based learning and others such as action learning, enquiry-based learning, and case studies. Faculty currently involved in EL at the participating university were invited to complete an online survey about their teaching and assessment methods. This paper will share the results and analysis of the EL inventory survey.

    Graduating Internal Medicine residents must possess sufficient skills to perform a variety of medical procedures. Little is known about resident experiences of acquiring procedural skills proficiency, of practicing these techniques, or of being assessed on their proficiency. The purpose of this study was to qualitatively investigate resident 1) experiences of the acquisition of procedural skills and 2) perceptions of procedural skills assessment methods available to them. Focus groups were conducted in the weeks following an assessment of procedural skills incorporated into an objective structured clinical examination (OSCE). Using fundamental qualitative description, emergent themes were identified and analyzed. Residents perceived procedural skills assessment on the OSCE as a useful formative tool for direct observation and immediate feedback. This positive reaction was regularly expressed in conjunction with a frustration with available assessment systems. Participants reported that proficiency was acquired through resident directed learning with no formal mechanism to ensure acquisition or maintenance of skills. The acquisition and assessment of procedural skills in Internal Medicine programs should move toward a more structured system of teaching, deliberate practice and objective assessment. We propose that directed, self-guided learning might meet these needs.

    1992-03-01

    Case study design was used in this investigation of the pupil assessment theories of two middle school physical education teachers whose program was identified as a good program in which pupil assessment was taking place. An assumption guiding the study was that teachers' actions are rational and are designed to produce desired results. Therefore, a comparison is made only between two theories of action (espoused and enacted) rather than between theory and practice. Informal and semistructured interviews were employed to elicit teachers' espoused theories, and enacted theories were identified during field visits over a semester in which classes were observed and school documents examined. Teachers' theories of assessment are identified for the categories of participation, effort, and improvement; grading; written tests; fitness testing; performance tests; and formative recordkeeping. Espoused and enacted theories are then examined for congruency. The highest level of incongruency was found in the areas of performance tests and formative recordkeeping. Barriers to the use of pupil assessment techniques in this program include organizational, knowledge, and contextual factors. Change in the assessment practices of secondary teachers may be facilitated, however, through the identification and examination of teachers' theories of assessment by both preservice and inservice teachers.

    The basic elements of human survival are based on the ecological environment. The development of social economic and the security of the ecological environment are closely linked and interact with each other. The fragility of the environment directly affects the stability of the regional ecosystem and the sustainable development of the ecological environment. As part of the division of the national ecological security, the assessment of ecological fragility has become a hot and difficult issue in environmental research, and researchers at home and abroad have systematically studied the causes and states of ecological fragility. The assessment of regional ecological fragility is a qualitative and quantitative analysis of the unbalanced distribution of ecological environment factors caused by human socio-economic activities or changes in ecosystems. At present, researches on ecological fragility has not formed a complete and unified index assessment system, and the unity of the assessment model has a direct impact on the accuracy of the index weights. Therefore, the discussion on selection of ecological fragility indexes and the improvement of ecological fragility assessment model is necessary, which is good for the improvement of ecological fragility assessment system in China.

    Schistosomiasis is a parasite-related chronic inflammatory condition that can cause anemia, decreased growth, liver abnormalities, and deficits in cognitive functioning among children. This study used the Behavior Assessment System for Children (BASC-2) to collect data on thirty-six 9-12 year old school-attending children's behavioral profiles in an Schistosoma mansoni-endemic area of western Kenya, before and after treatment with praziquantel for S. mansoni infection. BASC-2 T scores were significantly reduced post-treatment (p behavior categories including externalizing problems (hyperactivity, aggression, and conduct problems that are disruptive in nature), internalizing problems (anxiety, depression, somatization, atypicality, and withdrawal), school problems (academic difficulties, included attention problems and learning problems), and the composite behavioral symptoms index (BSI), signifying improved behavior. While the observed improvement in the 'positive' behavior category of adaptive skills (adaptability, functional communication, social skills, leadership, and study skills) was not statistically significant, there were significant improvements in two adaptive skills subcategories: social skills and study skills. Results of this study suggest that children have better school-related behaviors without heavy S. mansoni infection, and that infected children's behaviors, especially disruptive problem behaviors, improve significantly after praziquantel treatment.

    2015-02-01

    Transthoracic echocardiography (TTE) is a widely used cardiac imaging technique that all cardiologists should be able to perform competently. Traditionally, TTE competence has been assessed by unstructured observation or in test situations separated from daily clinical practice. An instrument for assessment of clinical TTE technical proficiency including a global rating score and a checklist score has previously shown reliability and validity in a standardised setting. As clinical test situations typically have several sources of error giving rise to variance in scores, a more thorough examination of the generalizability of the assessment instrument is needed. Nine physicians performed a TTE scan on the same three patients. Then, two raters rated all 27 TTE scans using the TTE technical assessment instrument in a fully crossed, all random generalizability study. Estimated variance components were calculated for both the global rating and checklist scores. Finally, dependability (phi) coefficients were also calculated for both outcomes in a decision study. For global rating scores, 66.6% of score variance can be ascribed to true differences in performance. For checklist scores this was 88.8%. The difference was primarily due to physician-rater interaction. Four random cases rated by one random rater resulted in a phi value of 0.81 for global ratings and two random cases rated by one random rater showed a phi value of 0.92 for checklist scores. Using the TTE checklist as opposed to the TTE global rating score had the effect of minimising the largest source of error variance in test scores. Two cases rated by one rater using the TTE checklist are sufficiently reliable for high stakes examinations. As global rating is less time consuming it could be considered performing four global rating assessments in addition to the checklist assessments to account for both reliability and content validity of the assessment.

    A main source of outdoor air pollution is road traffic, which produces a complex mixture of nitrogen oxides, carbon monoxide, volatile hydrocarbons, airborne particles and some other compounds. Traffic exhaust affects also the concentrations of ozone and other photo chemical oxidants. In earlier studies those components have had remarkable health effects. Several studies on occupational exposure to automobile exhaust have been published and several studies have been observed an association between both outdoor and indoor pollutant levels and health outcomes. However, there are only a few epidemiological studies in which traffic exhaust, a complex mixture, has been studied in its entirety. During recent years, interesting epidemiological studies of the health effects of this complex mixture have been published. Human exposure assessment for traffic exhaust can be categorized according to the environment of exposure (indoors, outdoors, in-traffic) or to the method of exposure assessment (direct or indirect methods). In this presentation the methods are further categorized into (1) traffic activity, (2) air concentration measurements, and (3) dispersion models, in order to better understand the advantages and disadvantages of different approaches. The objective of this presentation is to make a critical review of exposure assessments in the epidemiological studies on health effects of traffic exhaust. (author)

    2014-10-15

    In this paper the authors propose a framework for combining life cycle assessment (LCA) and Risk Assessment (RA) to support the sustainability assessment of emerging technologies. This proposal includes four steps of analysis: technological system definition; data collection; risk evaluation and impacts quantification; results interpretation. This scheme has been applied to a case study of nanofluid alumina production in two different pilot lines, "single-stage" and "two-stage". The study has been developed in the NanoHex project (enhanced nano-fluid heat exchange). Goals of the study were analyzing the hotspots and highlighting possible trade-off between the results of LCA, which identifies the processes having the best environmental performance, and the results of RA, which identifies the scenarios having the highest risk for workers. Indeed, due to lack of data about exposure limits, exposure-dose relationships and toxicity of alumina nanopowders (NPs) and nanofluids (NF), the workplace exposure has been evaluated by means of qualitative risk assessment, using Stoffenmanager Nano. Though having different aims, LCA and RA have a complementary role in the description of impacts of products/substances/technologies. Their combined use can overcome limits of each of them and allows a wider vision of the problems to better support the decision making process. Copyright © 2014 Elsevier B.V. All rights reserved.

    2017-03-01

    Full Text Available Introduction: Melasma is a recurrent, symmetric, and chronic acquired hyperpimentation that presents gray-brown macules and patches with determined margins in areas exposed to light. Thre are many treatment options with diffrent efficies and side effcts. In this study the therapeutic effct of 20% azelaic acid and 4% hydroquinone in treatment of melasma was assessed. Methods: In this clinical trial, the study population consisted of all patients with clinical diagnosis of melasma, who referred to the outpatient clinic of dermatology of Hamadan, Farshchian Hospital from December 2013 to July 2014. A total of 44 patients were recruited. Patients were randomly divided to two groups and each group was treated with either azelaic acid or hydroquinone for four months. Th MASI score was used to evaluate the improvement. P values of ≤ 0.05 were considered signifiant. Results: Of 44 patients, 21 received 4% hydroquinone and 23 received 20% azelaic acid, with random allocation. Both groups were similar with respect to gender and age, and there were no signifiant diffrences between the two groups. Th MASI score in both groups had a decreasing trend over time, and at the end of the fourth month, a signifiant diffrence was found between the two groups P = 0.006(. Th overall mean MASI score in both groups had a signifiant diffrence at diffrent times and during the entire trial period, mean MASI score of 20% azelaic acid was lower than 4% hydroquinone P = 0.001(. Conclusion: Based on this study, we could conclude that 20% azelaic acid in comparison with 4% hydroquinone had bettr effcts on treatment of melasma. Threfore, 20% azelaic acid is a good alternative for 4% hydroquinone in treatment of melasma.

  4. Methods of synthesizing qualitative research studies for health technology assessment.

    2011-10-01

    Synthesizing qualitative research is an important means of ensuring the needs, preferences, and experiences of patients are taken into account by service providers and policy makers, but the range of methods available can appear confusing. This study presents the methods for synthesizing qualitative research most used in health research to-date and, specifically those with a potential role in health technology assessment. To identify reviews conducted using the eight main methods for synthesizing qualitative studies, nine electronic databases were searched using key terms including meta-ethnography and synthesis. A summary table groups the identified reviews by their use of the eight methods, highlighting the methods used most generally and specifically in relation to health technology assessment topics. Although there is debate about how best to identify and quality appraise qualitative research for synthesis, 107 reviews were identified using one of the eight main methods. Four methods (meta-ethnography, meta-study, meta-summary, and thematic synthesis) have been most widely used and have a role within health technology assessment. Meta-ethnography is the leading method for synthesizing qualitative health research. Thematic synthesis is also useful for integrating qualitative and quantitative findings. Four other methods (critical interpretive synthesis, grounded theory synthesis, meta-interpretation, and cross-case analysis) have been under-used in health research and their potential in health technology assessments is currently under-developed. Synthesizing individual qualitative studies has becoming increasingly common in recent years. Although this is still an emerging research discipline such an approach is one means of promoting the patient-centeredness of health technology assessments.

  5. Assessing ant seed predation in threatened plants: a case study

    2005-11-01

    Erodium paularense is a threatened plant species that is subject to seed predation by the granivorous ant Messor capitatus. In this paper we assessed the intensity and pattern of ant seed predation and looked for possible adaptive strategies at the seed and plant levels to cope with this predation. Seed predation was estimated in 1997 and 1998 at the population level by comparing total seed production and ant consumption, assessed by counting seed hulls in refuse piles. According to this method, ant seed predation ranged between 18% and 28%. A more detailed and direct assessment conducted in 1997 raised this estimate to 43%. In this assessment spatial and temporal patterns of seed predation by ants were studied by mapping all nest entrances in the studied area and marking the mature fruits of 109 reproductive plants with a specific colour code throughout the seed dispersal period. Intact fruit coats were later recovered from the refuse piles, and their mother plants and time of dispersal were identified. Seeds dispersed at the end of the dispersal period had a greater probability of escaping from ant seed predation. Similarly, in plants with late dispersal a greater percentage of seeds escaped from ant predation. Optimum dispersal time coincided with the maximum activity of granivorous ants because, at this time, ants focused their harvest on other plant species of the community. It was also observed that within-individual seed dispersal asynchrony minimised seed predation. From a conservation perspective, results show that the granivorous ant-plant interaction cannot be assessed in isolation and that the intensity of its effects basically depends on the seed dispersal pattern of the other members of the plant community. Furthermore, this threat must be assessed by considering the overall situation of the target population. Thus, in E. paularense, the strong limitation of safe-sites for seedling establishment reduces the importance of seed predation.

    Background Self-assessment is recognized as a necessary skill for lifelong learning. It is widely reported to offer numerous advantages to the learner. The research evaluated the impact of students’ and supervisors’ self-assessment and feedback training on students’ perceptions and practices of self-assessment. Moreover, it evaluated the effect of self-assessment process on students’ study strategies within a community of clinical practice. Methods We conducted a qualitative phenomenological study from May 2008 to December 2009. We held 37 semi-structured individual interviews with three different cohorts of undergraduate medical students until we reached data saturation. The cohorts were exposed to different contexts while experiencing their clinical years’ assessment program. In the interviews, students’ perceptions and interpretations of ‘self-assessment practice’ and ‘supervisor-provided feedback’ within different contexts and the resulting study strategies were explored. Results The analysis of interview data with the three cohorts of students yielded three major themes: strategic practice of self-assessment, self-assessment and study strategies, and feedback and study strategies. It appears that self-assessment is not appropriate within a summative context, and its implementation requires cultural preparation. Despite education and orientation on the two major components of the self-assessment process, feedback was more effective in enhancing deeper study strategies. Conclusion This research suggests that the theoretical advantages linked to the self-assessment process are a result of its feedback component rather than the practice of self-assessment isolated from feedback. Further research exploring the effects of different contextual and personal factors on students’ self-assessment is needed. PMID:22355241

  7. Methodologic assessment of studies on endoscopic sinus surgery.

    2003-11-01

    Functional endoscopic sinus surgery (ESS) has become the procedure of choice for surgical treatment of chronic rhinosinusitis. Does the published literature support the claims of greater efficacy than medical treatment alone or older sinus procedures? To analyze the methodology of the published literature regarding the efficacy of ESS. MEDLINE search for primary studies published in 1987 through 2001, written in the English language, reporting results on more than 100 patients, using the MeSH (medical subject headings) terms sinusitis [subheadings surgery or therapy] and endoscopy. Of 512 studies initially identified, 29 studies met the inclusion and exclusion criteria for further assessment of methodologic criteria. An additional 6 studies were found when the reference lists of reviews or included studies were searched. Articles were evaluated for 4 core (inclusion/exclusion criteria, control group, intervention, and clear outcome measure) methodologic criteria essential to the determination of efficacy of ESS. Eight additional methodologic criteria were also used to rate the articles. Three studies met all 4 core methodologic criteria. Only 4 of 35 studies used a control group to evaluate efficacy of ESS to treat chronic sinusitis. Mean number of criteria met was 7.2, with a range of 2 to 11. Absence of a control group is the most important reason that studies are unable to scientifically assess the comparative efficacy of ESS to medical therapy or other sinus procedures. The methodologic criteria described here can be used to evaluate studies of interventions for other disorders.

    In children, dental anxiety and fear of dental treatment have been recognized as a source of problems in patient management for many years, which can affect the quality of care. Aims : The aim of the study was to assess the behavior of children during their dental visit and to determine the effect of behavior management techniques on children. Materials and Methods : A retrospective study was done by analyzing the records of 328 children to assess their behavior during dental visits. Behavior assessment was done using Frankl's behavior rating scale. All children were exposed to live modeling and tell-show-do behavior management technique. Statistical analysis : The analysis was carried out using SPSS version 10. The comparison between visits was carried out by applying Friedman test. Results and conclusion : Children showed improvement in their behavior with every subsequent visits. Proper assessment of children's behavior helps the dentist to execute a required treatment plan in the most appropriate manner. Techniques like live modeling and tell-show-do are very effective in modifying a child's behavior.

    The purpose of this study was to characterize the neuropsychiatric profile of elderly patients with schizophrenia and establish a patient registry for prospective ante-mortem and post-mortem studies. Medical records of all chronically institutionalized patients in eight state hospitals who were over the age of 65 and had a chart diagnosis of schizophrenia (N = 528) were reviewed. Of the potential subjects, 192 were excluded because of clinical histories inconsistent with a diagnosis of schizophrenia, 56 because of insufficient information to establish a psychiatric diagnosis, and 122 because of family members' refusal to give consent for autopsy in the event of death. To date, 81 of the remaining 158 patients have undergone neuropsychiatric evaluation with standard assessment instruments. Mini-Mental State scores of the 81 patients indicated severe dementia, and Functional Assessment Scale scores showed that patients required assistance with activities of daily living. All patients were rated as severely ill on the Brief Psychiatric Rating Scale. Ratings on the Scale for the Assessment of Negative Symptoms and the Scale for the Assessment of Positive Symptoms indicated a predominance of negative symptoms over positive. Of 30 patients who have died to date, research autopsies have been conducted on 26. Establishing a well characterized, prospective patient registry for clinicopathologic studies of schizophrenia is feasible but labor intensive. Diagnosis of schizophrenia with a high degree of confidence can be achieved by means of detailed chart review and assessment of current neuropsychiatric functioning with standard rating instruments. These data provide a basis for correlations of clinicopathologic factors.

    This work presents a comparison between an environmental impact assessment (EIA) and a life cycle assessment (LCA) using a case study: upgrading of biogas. The upgrading of biogas is studied using three solvents: water, physical solvent and amine. The EIA follows the requirements of the legislation of Santa Fe Province (Argentina), and the LCA follows ISO 14040. The LCA results showed that water produces a minor impact in most of the considered categories whereas the high impact in the process with amines is the result of its high energy consumptions. The positive results obtained in the EIA (mainly associated with the cultural and socioeconomic components) make the project feasible and all the negative impacts can be mitigated by preventive and remedial measures. From the strengths and weaknesses of each tool, it is inferred that the EIA is a procedure that can complement the LCA. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The purpose of this clinical feasibility study was to evaluate the applicability of magnetic resonance imaging (MRI) for the assessment of apical periodontitis in direct comparison with cone beam CT (CBCT). 19 consecutive patients (average age 43 ± 13 years) with 34 lesions in total (13 molars, 14 premolars and 7 front teeth) were enrolled in this feasibility study. Periapical lesions were defined as periapical radiolucencies (CBCT) or structural changes in the spongy bone signal (MRI), which were connected with the apical part of a root and with at least twice the width of the periodontal ligament space. The location and dimension of the lesions were compared between MRI and CBCT. While mainly mineralized tissue components such as teeth and bone were visible with CBCT, complimentary information of the soft tissue components was assessable with MRI. The MRI images provided sufficient diagnostic detail for the assessment of the main structures of interest. Heterogeneous contrast was observed within the lesion, with often a clear enhancement close to the apical foramen and the periodontal gap. No difference for lesion visibility was observed between MRI and CBCT. The lesion dimensions corresponded well, but were slightly but significantly overestimated with MRI. A heterogeneous lesion appearance was observed in several patients. Four patients presented with a well circumscribed hyperintense signal in the vicinity of the apical foramen. The MRI capability of soft tissue characterization may facilitate detailed analysis of periapical lesions. This clinical study confirms the applicability of multi-contrast MRI for the identification of periapical lesions.

    This study falls within the framework of the incorporation of quantitative risk assessment to the activities planned for the ESA-HERMES project (ESA/ CNES). The main objective behind the study was the analysis and evaluation of the potential contribution of so-called probabilistic or quantitative safety analysis to the optimization of the safety development process for the systems carrying out the safety functions required by the new and complex HERMES Space Vehicle. For this purpose, a pilot study was considered a good start in quantitative safety assessments (QSA), as this approach has been frequently used in the past to establish a solid base in large-scale QSA application programs while avoiding considerable economic risks. It was finally decided to select the HERMES docking/berthing system with Man Tender Free Flyer as the case-study. This report describes the different steps followed in the study, along with the main insights obtained and the general conclusions drawn from the study results. (author)

    attempt has been made to capture the new trends in the regulations, to the extent they are known. There have over the last 10-15 years been published a few textbooks on risk assessment, most of them are devoted to relatively generic topics. Some are also focused on the risk management aspects, in general and with offshore applicability. None are known to address the needs and topics of the use of QRA studies by the offshore industry in particular. The present work is trying to bridge this gap. The use of QRA studies is somewhat special in Northern Europe, and par- cularly in Norway. The use of

    In the framework of an epidemiological study, dosemeters were used for the assessment of radio frequency electromagnetic field exposure. To check the correct dosemeter's performance in terms of consistency of recorded field values over the entire study period, a quality control strategy...... was developed. In this paper, the concept of quality control and its results is described. From the 20 dosemeters used, 19 were very stable and reproducible, with deviations of a maximum of +/-1 dB compared with their initial state. One device was found to be faulty and its measurement data had to be excluded...

    A pilot study of Seaside, Oregon is underway, to develop methodologies for probabilistic tsunami hazard assessments that can be incorporated into Flood Insurance Rate Maps (FIRMs) developed by FEMA's National Flood Insurance Program (NFIP). Current NFIP guidelines for tsunami hazard assessment rely on the science, technology and methodologies developed in the 1970s; although generally regarded as groundbreaking and state-of-the-art for its time, this approach is now superseded by modern methods that reflect substantial advances in tsunami research achieved in the last two decades. In particular, post-1990 technical advances include: improvements in tsunami source specification; improved tsunami inundation models; better computational grids by virtue of improved bathymetric and topographic databases; a larger database of long-term paleoseismic and paleotsunami records and short-term, historical earthquake and tsunami records that can be exploited to develop improved probabilistic methodologies; better understanding of earthquake recurrence and probability models. The NOAA-led U.S. National Tsunami Hazard Mitigation Program (NTHMP), in partnership with FEMA, USGS, NSF and Emergency Management and Geotechnical agencies of the five Pacific States, incorporates these advances into site-specific tsunami hazard assessments for coastal communities in Alaska, California, Hawaii, Oregon and Washington. NTHMP hazard assessment efforts currently focus on developing deterministic, "credible worst-case" scenarios that provide valuable guidance for hazard mitigation and emergency management. The NFIP focus, on the other hand, is on actuarial needs that require probabilistic hazard assessments such as those that characterize 100- and 500-year flooding events. There are clearly overlaps in NFIP and NTHMP objectives. NTHMP worst-case scenario assessments that include an estimated probability of occurrence could benefit the NFIP; NFIP probabilistic assessments of 100- and 500-yr

    Family-based association tests such as the transmission disequilibrium test (TDT) are dependent on the successful ascertainment of true nuclear family trios. Relationship misspecification inevitably occurs in a proportion of trios collected for genotyping which undetected can lead to a loss of power and increased Type I error due to biases in over-transmission of common alleles. Here, we introduce a method for evaluating the authenticity of nuclear family trios. Operating in a Bayesian framework, our approach assesses the extent of pedigree inconsistent genotype configurations in the presence of genotyping errors. Unlike other approaches, our method: (i) utilizes information from three individuals collectively (the whole trio) rather than consider two independent pairwise relationships; (ii) down-weighs SNPs with poor performance; (iii) does not require the user to pre-define a rate of genotyping error, which is often unknown to the user and seldom fixed across the different SNPs considered which available methods unrealistically assumed. Simulation studies and comparisons with a real set of data showed that our approach is more likely to correctly identify the presence of true and misspecified trios compared to available software, accurately infers the extent of relationship misspecification in a trio and accurately estimates the genotyping error rates. Assessing relationship misspecification depends on the fidelity of the genotype data used. Available algorithms are not optimised for genotyping technology with varying rates of errors across the markers. Through our comparison studies, our approach is shown to outperform available methods for assessing relationship misspecifications. Copyright 2008 S. Karger AG, Basel.

    Delays in the development of executive functioning skills are frequently observed in pediatric neuropsychology populations and can have a broad and significant impact on quality of life. As a result, assessment of executive functioning is often relevant for the development of formulations and recommendations in pediatric neuropsychology clinical work. Questionnaire-based measures of executive functioning behaviors in everyday life have unique advantages and complement traditional neuropsychological measures of executive functioning. Two case studies of children with spina bifida are presented to illustrate the clinical use of a new questionnaire measure of executive and learning-related functioning, the Learning, Executive, and Attention Functioning Scale (LEAF). The LEAF emphasizes clinical utility in assessment by incorporating four characteristics: brevity in administration, breadth of additional relevant content, efficiency of scoring and interpretation, and ease of availability for use. LEAF results were consistent with another executive functioning checklist in documenting everyday behavior problems related to working memory, planning, and organization while offering additional breadth of assessment of domains such as attention, processing speed, and novel problem-solving. These case study results demonstrate the clinical utility of questionnaire-based measurement of executive functioning in pediatric neuropsychology and provide a new measure for accomplishing this goal.

    Full Text Available Abstract Background To describe approaches used in systematic reviews of diagnostic test accuracy studies for assessing variability in estimates of accuracy between studies and to provide guidance in this area. Methods Meta-analyses of diagnostic test accuracy studies published between May and September 2012 were systematically identified. Information on how the variability in results was investigated was extracted. Results Of the 53 meta-analyses included in the review, most (n=48; 91 % presented variability in diagnostic accuracy estimates visually either through forest plots or ROC plots and the majority (n=40; 75 % presented a test or statistical measure for the variability. Twenty-eight reviews (53 % tested for variability beyond chance using Cochran’s Q test and 31 (58 % reviews quantified it with I2. 7 reviews (13 % presented between-study variance estimates (τ2 from random effects models and 3 of these presented a prediction interval or ellipse to facilitate interpretation. Half of all the meta-analyses specified what was considered a significant amount of variability (n=24; 49 %. Conclusions Approaches to assessing variability in estimates of accuracy varied widely between diagnostic test accuracy reviews and there is room for improvement. We provide initial guidance, complemented by an overview of the currently available approaches.

    In March 2011, the U.S. Department of Energy (DOE) awarded White Pine County, Nevada, a grant to assess the feasibility of renewable resource-related economic development activities in the area. The grant project included a public outreach and training component and was to include a demonstration project; however, the demonstration project was not completed due to lack of identification of an entity willing to locate a project in White Pine County. White Pine County completed the assessment of renewable resources and a feasibility study on the potential for a renewable energy-focused economic sector within the County. The feasibility study concluded "all resources studied were present and in sufficient quantity and quality to warrant consideration for development" and there were varying degrees of potential economic impact based on the resource type and project size. The feasibility study and its components were to be used as tools to attract potential developers and other business ventures to the local market. White Pine County also marketed the County’s resources to the renewable energy business community in an effort to develop contracts for demonstration projects. The County also worked to develop partnerships with local educational institutions, including the White Pine County School District, conducted outreach and training for the local community.

    In August 1978, the United States Department of Energy and the Turlock Irrigation District entered into a cooperative agreement for a Joint District's Low-Head Hydropower Assessment Study. The purpose of the agreement was to carry out a study of the hydropower potential at sites within the borders of the Turlock, Merced, South San Joaquin, and Oakdale Irrigation Districts in California. The required data were gathered and analyzed. The results of this study indicate the total potential small hydropower capacity with the Joint Districts is 19,560 kW installed with an annual energy generation of 68,561,800 kWh. This is equivalent to oil-savings of 118,616 barrels per y.

    This paper summarizes the status of a research project sponsored by EPRI as part of the Probabilistic Risk Assessment (PRA) technology improvement program and conducted by NUS Corporation to develop a model of Human Cognitive Reliability (HCR). The model was synthesized from features identified in a review of existing models. The model development was based on the hypothesis that the key factors affecting crew response times are separable. The inputs to the model consist of key parameters the values of which can be determined by PRA analysts for each accident situation being assessed. The output is a set of curves which represent the probability of control room crew non-response as a function of time for different conditions affecting their performance. The non-response probability is then a contributor to the overall non-success of operating crews to achieve a functional objective identified in the PRA study. Simulator data and some small scale tests were utilized to illustrate the calibration of interim HCR model coefficients for different types of cognitive processing since the data were sparse. The model can potentially help PRA analysts make human reliability assessments more explicit. The model incorporates concepts from psychological models of human cognitive behavior, information from current collections of human reliability data sources and crew response time data from simulator training exercises

    Full Text Available Structural health assessment is one of the key activities in maintaining the performance of a tunnel during its service life. Due to the development of modern detection technology, comprehensive structural health assessment system is being established for operating tunnels. To evaluate the actual operational state of Shitigou tunnel, overall detection of the liner crack, tunnel seepage, and liner void was conducted by employing the modern detection technology, such as crack width monitoring technology, concrete strength monitoring technology, and electromagnetic wave nondestructive monitoring technology. Through the statistical analysis of the detection results, the distribution characteristic, development law, and damage grade of structural defects were obtained. Tunnel liner cracks are mainly located on the middle wall; serious water leakage is encountered on the side wall, middle wall, and vault; the strength of foundation and liner structure of left tunnel does not meet the design requirement; the liner voids are mostly located at the tunnel entrance section, especially, on the tunnel vault; and the proportion of influence factors of structural defects should be considered. The research results presented for this study can serve as references for effective design and health assessment of existing multiarch tunnel projects.

    The establishment of the Framework Convention on Climate change has motivated a large number of mitigation costing studies of developing countries. A variety of modelling approaches and input assumptions have been employed, and studies have been carried out by a range of institutions, including international research institutions, consultants and national organisations. This paper attempts to bring together the main results and characteristics of some of the major recent studies. In spite of the diversity of teams involved in the studies, the similarities in scenario definitions and in the bottom-up approach used for the energy sector analysis, enable some key macro indicators and results of the studies to be compared. Two main coordinated country study efforts have been carried out: by the Lawrence Berkeley Laboratory (LBL) and by UNEP collaborating Centre on Energy and Environment (UCCEE). The results and methodological framework of these country studies are assessed in relation to similar country study activities for China, West Africa and South East Asia in order to evaluate possible common conclusions.

    Full Text Available The inherent complexity of environmental performance measurement makes it difficult to be gauged, sending it forth to methodologies supported on assessments of the various factors that could influence the overall performance. In association with the environmental performance lies the need to create methods that allows the assessment over the time in order to facilitate comparisons amongst different organizations or operations of a same company. Measurement of environmental performance comes from several sources thus a dominant approach widely recognized and accepted by the academic community and organizations can not be singled out. The purpose of this review is to test a method for assessing environmental performance in a manufacturer organization, performing a case study in the paper industry. The results can be compared with other operations and can be used, cumulatively, in supply chains. The specific objectives are (i to model the environmental performance of the transaction, (ii to use the model to measure performance, and (iii to interpret the results and come to a conclusion. It begins with a review of the environmental performance measurement and then proceeds to the description of the research methodology and the results of its application. The method consists of five constructs, assessed by managers and processes experts according to their potential of environmental performance's improvement: solid waste, wastewater, gas emissions, deployment of natural resources, and legal compliance. The constructs are perceived by qualitative indicators categorically evaluated. The final result is an index of 76.69%, which represents the environmental performance of the operation.

    This study aims to broaden knowledge about pain expression and assessment in daily life situations in children with Autism Spectrum Disorder (ASD). The goals are to provide a description of the responses of the GED-DI, the French version of the NCCPC, and to test the internal structure validity of this scale. Thirty five children with ASD were included in this study (mean age=58months; mean developmental age=32months). The French version of the NCCPC was filled in by parents. Descriptive analysis of responses shows that children with ASD express pain through varied and common behaviours, related to different expressive markers (vocal, facial, activity, etc.). Behaviours more specific to the symptomology and disturbances of ASD are also displayed. A four-factor solution (negative emotional reaction, idiosyncratic expression, hyper-vigilance reaction, pain expression) emerges from an exploratory factor analysis that explains 54.4% of the total variance. Correlation coefficients show good psychometric qualities in terms of internal consistency, factorial validity and discriminant validity. This study provides new data about pain expression in daily life situations and shows that the French version of NCCPC adjusted to ASD children is relevant to assess pain in daily life situations.

    Associated with the tremendous prosperity in world electronic information and telecommunication industry, there continues to be an increasing awareness of the environmental impacts related to the accelerating mass production, electricity use, and waste management of electronic and electric products (e-products). China's importance as both a consumer and supplier of e-products has grown at an unprecedented pace in recent decade. Hence, this paper aims to describe the application of life cycle assessment (LCA) to investigate the environmental performance of Chinese e-products from a global level. A desktop personal computer system has been selected to carry out a detailed and modular LCA which follows the ISO 14040 series. The LCA is constructed by SimaPro software version 7.0 and expressed with the Eco-indicator'99 life cycle impact assessment method. For a sensitivity analysis of the overall LCA results, the so-called CML method is used in order to estimate the influence of the choice of the assessment method on the result. Life cycle inventory information is complied by ecoinvent 1.3 databases, combined with literature and field investigations on the present Chinese situation. The established LCA study shows that that the manufacturing and the use of such devices are of the highest environmental importance. In the manufacturing of such devices, the integrated circuits (ICs) and the Liquid Crystal Display (LCD) are those parts contributing most to the impact. As no other aspects are taken into account during the use phase, the impact is due to the way how the electricity is produced. The final process steps - i.e. the end of life phase - lead to a clear environmental benefit if a formal and modern, up-to-date technical system is assumed, like here in this study

    Tremendous research efforts have been devoted to fabricating high quality quantum dots (QDs) for applications in biology and medicine. Much of this research was pursued with an ultimate goal of using QDs in clinical applications. However, a great deal of concern has been voiced about the potential hazards of QDs due to their heavy-metal content. Many studies have demonstrated toxicity of various QDs in cell culture studies. However, in a smaller number of studies using small animal models (mice and rats), no abnormal behaviour or tissue damage was noticed over periods of months after the systemic administration of QDs. Nevertheless, the correlation of these results with the potential for negative effects of QD on humans remains unclear. Many urgent questions must be answered before the QDs community moves into the clinical research phase. This review provides an overview of the toxicity assessment of QDs, ranging from cell culture studies to animal models and discusses their findings. Guidelines for using various nonhuman primate models for QD toxicity studies are highlighted. This review article is intended to promote the awareness of current developments of QD applications in biology, the potential toxicity of QDs, and approaches to minimizing toxicity.

    Numerous epidemiological accounts suggest that waterpipe smoking (aka hookah, shisha, narghile) has become a global phenomenon, especially among youth. The alarming spread of waterpipe and accumulating evidence of its addictive and harmful effects represent a new threat in the global fight to limit tobacco-related morbidity and mortality. In response to waterpipe's alarming trends, major public health and tobacco control organisations have started or are considering systematic collection of data about waterpipe smoking to monitor its trends and assess its harmful effects in different societies. Such plans require coordination and agreement on epidemiological measurement tools that reflect the uniqueness of this tobacco use method, and at the same time allow comparison of waterpipe trends across time and place, and with other tobacco use methods. We started a decade ago our work to develop standardised measures and definitions for the assessment of waterpipe smoking in epidemiological studies. In this communication, we try to expand and update these assessment tools in light of our increased knowledge and understanding of waterpipe use patterns, its context and marketing, as well as the need for evidence-guided policies and regulations to curb its spread. We have assembled for this purpose a group of leading waterpipe researchers worldwide, and worked through an iterative process to develop the suggested instruments and definitions based on what we know currently about the waterpipe epidemic. While the suggested measures are by no means comprehensive, we hope that they can provide the building blocks for standard and comparable surveillance of waterpipe smoking globally.

    It is reputed that periodontal indices remain unchanged over a 24-hour period, with great clinical significance. This preliminary study analyzes daily index changes. In 56 selected patients, full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), periodontal screening and recording (PSR) indices, and periodontal risk assessment (PRA) were recorded at baseline and three times per day (check-I: 08.30, check-II: 11.30, and check-III: 14.30), after appropriate cause-related therapy. Correlation between variables was statistically analyzed by Stata. All periodontal indices improved at the examination phase. Statistical differences were detected for FMPS comparing all thrice daily checks. Statistical differences were detected for FMBS and PRA comparing check-III with check-I and check-II. PSR showed no significant changes. The worst baseline indices produced the widest daily fluctuation at the examination phase. Significant variation of indices is directly related to clinical severity of periodontal conditions at baseline. Patients affected by severe periodontal disease may show significantly greater index changes. As indices are routinely recorded only once per day, the index daily variation has clinical significance. This greatly affects therapeutic strategy as correct periodontal assessment requires multiple evaluations at standardized times, particularly when baseline conditions are severe. PMID:28828006

    Full Text Available Background: Nursing as a clinical discipline is developing in the emergency wards. Health care systems should continuously assess and prioritize indicators of clinical competency in these wards. The lack of clear standards of clinical competency indicators challenges evaluation. The purpose of this study was to determine clinical competency indicators and its priority based on nurses' views in educational and therapeutic centers in Guilan. Materials and Methods: The Q methodology was conducted in three phases, that is, phase I (determining the clinical competency indicators, phase II (classifying clinical competency indicators by an expert panel, and phase III (prioritizing clinical competency indicators. The subjects were selected by convenience sampling among nurses working in the emergency wards of teaching hospitals affiliated to Guilan in 2013. Finally, clinical competency indicators were prioritized using exploratory factor analysis. Results: In the prioritizing phase, data were collected from 710 nurses over two months. Five factors with 30 general competencies were found in three domains: communication, professional maturity, and personality characteristics. Six factors with 37 specific competencies were also found in two domains: scientific and technical capabilities and basic clinical skills that can provide a structured instrument for assessing clinical competence in emergency nurses. Conclusions: Achieved competencies can be used as a reference for nursing education and practice in emergency. Further research on health care system is needed in order to achieve a reliable and valid instrument.

    A high proportion of children have overweight and obesity in the United States and other countries. Accurate assessment of anthropometry is essential to understand health effects of child growth and adiposity. Gold standard methods of measuring adiposity, such as dual X-ray absorptiometry (DXA), may not be feasible in large field studies. Research staff can, however, complete anthropometric measurements, such as body circumferences and skinfold measurements, using inexpensive portable equipment. In this protocol we detail how to obtain manual anthropometric measurements from children, including standing and sitting height, weight, waist circumference, hip circumference, mid-upper arm circumference, triceps skinfold thickness, and subscapular skinfold thickness, and procedures to assess the quality of these measurements. To demonstrate accuracy of these measurements, among 1,110 school-aged children in the pre-birth cohort Project Viva we calculated Spearman correlation coefficients comparing manual anthropometric measurements with a gold standard measure of body fat, DXA fat mass 1 . To address reliability, we evaluate intra-rater technical error of measurement at a quality control session conducted on adult female volunteers.

    The goal of this study is to use life cycle assessment (LCA) tool to assess possible environmental impacts of different municipal solid waste management (MSWM) scenarios on various impact categories for the study area Dhanbad City, India. The scenarios included in the present study are collection and transportation (denoted as S1); baseline scenario consisting of recycling, open burning, open dumping, and finally unsanitary landfilling without energy recovery (denoted by S2); composting and landfilling (denoted by S3); and recycling and composting followed by landfilling of inert waste without energy recovery (denoted by S4). One ton of municipal solid waste (MSW) was selected as the functional unit. The primary data were collected through sampling, surveys, and literatures. Background data were obtained from Eco-invent data of SimaPro 8.1 libraries. The scenarios were compared using the CML 2 baseline 2000 method, and the results indicated that the scenario S1 had the highest impact on marine aquatic ecotoxicity (1.86E + 04 kg 1,4-DB eq.) and abiotic depletion (2.09E + 02 kg Sb eq.). S2 had the highest impact on global warming potential (9.42E + 03 kg CO 2 eq.), acidification (1.15E + 01 kg SO 2 eq.), eutrophication (2.63E + 00 kg PO 4 3- eq.), photochemical oxidation (2.12E + 00 kg C 2 H 4 eq.), and human toxicity (2.25E + 01 kg 1,4-DB eq.). However, S3 had the highest impact on abiotic depletion (fossil fuels) (2.71E + 02 MJ), fresh water aquatic ecotoxicity (6.54E + 00 kg 1,4-DB eq.), terrestrial ecotoxicity (3.36E - 02 kg 1,4-DB eq.), and ozone layer depletion (2.73E - 06 kg CFC-11 eq.). But S4 did not have the highest impact on any of the environmental impact categories due to recycling of packaging waste and landfilling of inert waste. Landfilling without energy recovery of mixed solid waste was found as the worst disposal alternative. The scenario S4 was found as the most environmentally suitable technology for the study

    Full Text Available Abstract Background In haplotype-based candidate gene studies a problem is that the genotype data are unphased, which results in haplotype ambiguity. The measure 1 quantifies haplotype predictability from genotype data. It is computed for each individual haplotype, and for a measure of global relative efficiency a minimum value is suggested. Alternatively, we developed methods directly based on the information content of haplotype frequency estimates to obtain global relative efficiency measures: and based on A- and D-optimality, respectively. All three methods are designed for single populations; they can be applied in cases only, controls only or the whole data. Therefore they are not necessarily optimal for haplotype testing in case-control studies. Results A new global relative efficiency measure was derived to maximize power of a simple test statistic that compares haplotype frequencies in cases and controls. Application to real data showed that our proposed method gave a clear and summarizing measure for the case-control study conducted. Additionally this measure might be used for selection of individuals, who have the highest potential for improving power by resolving phase ambiguity. Conclusion Instead of using relative efficiency measure for cases only, controls only or their combined data, we link uncertainty measure to case-control studies directly. Hence, our global efficiency measure might be useful to assess whether data are informative or have enough power for estimation of a specific haplotype risk.

    The concept of User System Architectures (USA) is introduced as part of the overall systems architecture. A USA is defined as a set of ergonomics information and knowledge assembled to represent system structure and content. It is described in the context of the system development lifecycle. The characteristics associated with a USA are outlined. These include layers of description, viewpoints, coherency and traceability. The concept of coherency between layers and the techniques for tracing the design characteristics back to the requirements (i.e. traceability) are discussed with their implications for ergonomics. Two studies (one design and one assessment) are used to demonstrate the use of USA techniques. The benefits, shortfalls and costs of using the USA technique are outlined for each case, and in a more general range of applications. The validity and reliability of the representations are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Providing a program in the concept development phase with a method of determining system safety benefits of potential concepts has always been a challenge. Lockheed Martin Space and Strategic Missiles has developed a methodology for developing a relative system safety ranking using the potential hazards of each concept. The resulting output supports program decisions with system safety as an evaluation criterion with supporting data for evaluation. This approach begins with a generic hazards list that has been tailored for the program being studied and augmented with an initial hazard analysis. Each proposed concept is assessed against the list of program hazards and ranked in three derived areas. The hazards can be weighted to show those that are of more concern to the program. Sensitivities can be also be determined to test the robustness of the conclusions

    Surface coal mines being the largest contributor to the national coal production, the study of environmental impacts due to this becomes mandatory as it will help in proper planning and safe operations of the mine in an environmentally compatible manner. Within the scope of this paper, a model for preparation of comprehensive environmental impact assessment (EIA) by utilising a new evaluation methodology leading to determination of Environmental Quality Designation an index has been developed and this model has been validated by using data from a running surface coal mine in Wardha Valley Coalfield. Based on this exercise, the overall impact of the surface coal mine under consideration on environment indicates a medium level and accordingly the control measures have to be planned. Thus repair to the environment has to be made a concurrent activity with mining i.e. to say we have to design with nature not against it

    The 2015 Informatics Needs and Capacity of Local Health Departments (LHDs) survey is the most recent comprehensive source of quantitative data on LHD informatics. Conducted by the National Association of County & City Health Officials (NACCHO), this is the third nationally representative quantitative study of LHD informatics since 2009. The previous 2 comprehensive quantitative assessments were conducted by NACCHO in 2009-2010 and 2011. Given that public health informatics is rapidly evolving, the 2015 Informatics survey is a much-needed country-wide assessment of the current informatics needs and capacities of LHDs. This article outlines detailed methodology used in the 2015 Informatics survey, including instrument development, pretesting, sampling design and sample size, survey administration, and sampling weights. A 9-member advisory committee representing federal, state, and local health agency representatives guided the design and implementation of this study. The survey instrument was organized into 6 topic areas: demographics, physical infrastructure, skills and capacity available, public health workforce development needs, electronic health records, and health information exchange. The instrument was pretested with a sample of 20 LHDs and subsequently pilot-tested with 30 LHDs. The survey was administered via the Qualtrics survey software to the sample of 650 LHDs, selected using stratified random sampling. The survey was fielded for approximately 8 weeks and 324 usable responses were received, constituting a response rate of 50%. Statistical weights were developed to account for 3 factors: (a) disproportionate response rate by population size (using 7 population strata), (b) oversampling of LHDs with larger population sizes, and (c) sampling rather than a census approach.

  9. Scaling studies and conceptual experiment designs for NGNP CFD assessment

    2004-11-01

    The objective of this report is to document scaling studies and conceptual designs for flow and heat transfer experiments intended to assess CFD codes and their turbulence models proposed for application to prismatic NGNP concepts. The general approach of the project is to develop new benchmark experiments for assessment in parallel with CFD and coupled CFD/systems code calculations for the same geometry. Two aspects of the complex flow in an NGNP are being addressed: (1) flow and thermal mixing in the lower plenum ("hot streaking" issue) and (2) turbulence and resulting temperature distributions in reactor cooling channels ("hot channel" issue). Current prismatic NGNP concepts are being examined to identify their proposed flow conditions and geometries over the range from normal operation to decay heat removal in a pressurized cooldown. Approximate analyses have been applied to determine key non-dimensional parameters and their magnitudes over this operating range. For normal operation, the flow in the coolant channels can be considered to be dominant turbulent forced convection with slight transverse property variation. In a pressurized cooldown (LOFA) simulation, the flow quickly becomes laminar with some possible buoyancy influences. The flow in the lower plenum can locally be considered to be a situation of multiple hot jets into a confined crossflow -- with obstructions. Flow is expected to be turbulent with momentumdominated turbulent jets entering; buoyancy influences are estimated to be negligible in normal full power operation. Experiments are needed for the combined features of the lower plenum flows. Missing from the typical jet experiments available are interactions with nearby circular posts and with vertical posts in the vicinity of vertical walls - with near stagnant surroundings at one extreme and significant crossflow at the other. Two types of heat transfer experiments are being considered. One addresses the "hot channel" problem, if necessary

    The urinary incontinence can affect up to 50% of women at some stage of their lives, particularly during pregnancy and postpartum. This study was designed in order to identify and assess the prevalence and risk factors for urinary incontinence during the third trimester of pregnancy and three months postpartum. Observational and cross-sectional study. The population of the study was composed of 268 women who delivered and were admitted to the Centro Hospitalar Tâmega e Sousa in the years 2013 and 2014, and who agreed to participate in this study. Postpartum women were asked to fill out a questionnaire adapted from the International Consultation on Incontinence Questionnaire - Short Form, for urinary incontinence research in the third trimester of pregnancy. Three months after delivery, they were contacted by telephone and asked to answer the same questions about the urinary incontinence postpartum. Of the 268 women interviewed, 31 were excluded from the study, taking into account the defined inclusion and exclusion criteria. In total (n = 237), 51.89% of women included in the study, reported the occurrence of urinary incontinence during pregnancy. The prevalence of urinary incontinence in pregnancy by parity (primiparous versus multiparous) was statistically significant (p = 0.006). At postpartum (n = 237), 28.69% of women with urinary incontinence had vaginal delivery and 5.91% of women underwent cesarean delivery (p = 0.001). In these group of women with postpartum urinary incontinence (n = 82), 31.69% have had urinary incontinence only in the postpartum and 68.31% of women have had symptoms during pregnancy (p urinary incontinence in pregnancy and the respective decrease in postpartum. Multiparity and occurrence of urinary incontinence in pregnancy appear as potential risk factors in the emergence of the urinary incontinence.

    Full Text Available Nowadays, floods are among the most impactful calamities regarding costs. Looking at the natural hazards damage data collected in the International Disaster Database (EM-DAT, it is observable a significant increase over the past four decades of both frequency of floods and associated costs. Similarly, dramatic trends are also found by analyzing other types of flood losses, such as the number of people affected by floods, homeless, injured or killed.To deal with the aforementioned rise of flood risk, more and more efforts are being made to promote integrated flood risk management, for example, the Flood Directive 2007/60/EC. The main goals of this research are the estimation of flood damages using the KULTURisk methodology and the comparing of the projected costs with the observed one. The case study is the 2002 flood in Eilenburg. According to KULTURisk methodology, two major classes of data are considered to evaluate flood risk damage: hydraulic data as regards Hazard and economic information to assess Exposure and Vulnerability This study shows the possibility to extend the lesson learned with the Eilenburg case study in other similar contexts.

    In Valdez, Alaska there is concern about exposure of the public to benzene and other light hydrocarbons emitted during the loading of tankers from the Trans-Alaska Pipeline. As part of an overall risk assessment, the Valdez Air Health Study, a personal, indoor and outdoor air sampling program patterned after EPA's TEMA Study was designed and carried out. A unique feature of the study is that, during sampling periods, SF 6 tracer was released at the terminal site to represent terminal hydrocarbon emissions to provide a basis for directly quantitating any contribution of terminal emissions to personal exposure. Sixty citizens at Valdez were selected to wear vests containing sampling equipment for 24-hour periods summer and winter. At the homes of 30 of the participants simultaneous indoor and outdoor samples for hydrocarbons and tracer were collected during the period that each participant collected personal air samples. The paper reviews the design of the program, details of the procedures used, results of the August, 1990 program and preliminary results from the February-March, 1991 program

    Because audiometric evaluation, symptom histories, questionnaires, and similar standard assessment tools may not adequately sample the effects of chronic tinnitus on day-to-day activities, there is a need for alternative methodological approaches to study the impact of tinnitus on day-to-day life. An innovative methodological approach that has shown great promise in the study of chronic health problems characterized by reported temporal and/or situational variability in symptoms and distress is known as ecological momentary assessment (EMA). EMA involves the real-time measurement of states, situational factors, and symptoms by individuals as they go about their day-to-day activities. The objective of this pilot investigation was to explore the feasibility of using EMA methods to examine within- and between-day effects of tinnitus. This study was conducted in three phases: (1) design and development of an EMA methodology that could be used to assess effects of tinnitus; (2) refinement of the methodology through the use of two focus groups; and (3) field-test the methodology with individuals who experienced bothersome tinnitus. For Phase 3, each of the 24 participants wore, throughout their waking hours for 2 weeks, a personal digital assistant that produced alerts four times a day. The alerts prompted participants to respond to 19 questions, including 9 relating to situational and mood factors and 10 comprising the Tinnitus Handicap Inventory-Screening version (THI-S). To evaluate for potential reactive effects of performing the EMA protocol, each participant completed the paper-and-pencil version of the full 25-item THI before and after the 2-week EMA period. Participants responded to the alerts with a 90% compliance rate, providing a total of 1210 completed surveys. At the time of their response, participants indicated that they were in their house or apartment (67.7%), alone (50.2%), happy (50%), and calm (54.5%). Across most responses, participants could hear

    Full Text Available Turkish education system has been developed taking into consideration a different perspective by setting a constructivist approach from the traditional concept of education since the 2005-2006 academic year. The restructured program has been implemented for 5 years. Research shows that many problems encountered during the implementation of the program. The encountered problems have been identified through a nationwide research study carried by EARGED in 2006 along with some other local level research studies. The purpose of this research is to determine how many of the problems, identified by EARGED’s study done in 2006, have been solved or addressed while how many of them have been still remaining. The data is collected from participants who are 6, 7 and 8th grade students who had taken social studies courses and their teachers in 16 public elementary schools located in Konya, Turkey. The collected data through this research study is compared with the findings of the EARGED’s research and a general assessment is made. asemi-structured interview schedule and a questionnaire were used to collect data from teachers and students. In qualitative analysis of the data literature which is related is scanned and descriptive analysis was conducted. Findings of this research reveals that teachers' training needs are observed mostly in areas such as “measurement and evaluation”,“knowledge about special education”, “use of information technologies” and “activity preparation” etc. and these problems still continue. At the same time the students’ problems are observed with “access to research resources”, “participation in activities or active involvement,” “teacher-student relations” and problems in such areas are still continuing

    Ray parenchyma is an essential tissue for tree functioning and survival. This living tissue plays a major role for storage and transport of water, nutrients, and non-structural carbohydrates (NSC), thus regulating xylem hydraulics and growth. However, despite the importance of rays for tree carbon and water relations, methodological challenges hamper knowledge about ray intra- and inter-tree variability and its ecological meaning. In this study we provide a methodological toolbox for soundly quantifying spatial and temporal variability of different ray features. Anatomical ray features were surveyed in different cutting planes (cross-sectional, tangential, and radial) using quantitative image analysis on stem-wood micro-sections sampled from 41 mature Scots pines (Pinus sylvestris). The percentage of ray surface (PERPAR), a proxy for ray volume, was compared among cutting planes and between early- and latewood to assess measurement-induced variability. Different tangential ray metrics were correlated to assess their similarities. The accuracy of cross-sectional and tangential measurements for PERPAR estimates as a function of number of samples and the measured wood surface was assessed using bootstrapping statistical technique. Tangential sections offered the best 3D insight of ray integration into the xylem and provided the most accurate estimates of PERPAR, with 10 samples of 4 mm(2) showing an estimate within ±6.0% of the true mean PERPAR (relative 95% confidence interval, CI95), and 20 samples of 4 mm(2) showing a CI95 of ±4.3%. Cross-sections were most efficient for establishment of time series, and facilitated comparisons with other widely used xylem anatomical features. Earlywood had significantly lower PERPAR (5.77 vs. 6.18%) and marginally fewer initiating rays than latewood. In comparison to tangential sections, PERPAR was systematically overestimated (6.50 vs. 4.92%) and required approximately twice the sample area for similar accuracy. Radial cuttings

    To analyze the factorial structure of a new instrument to assess the quality of the family context (Etxadi-Gangoiti Scale) in a sample from the Gipuzkoa cohort of the Environment and Childhood (Infancia y Medio Ambiente [INMA]) study. Families in a sample of 433 two-year-old children were assessed in a home visit with subsequent analysis of the factorial structure and psychometric properties of the data. An exploratory factorial analysis (principal axis factoring and varimax rotation) and a confirmatory factorial analysis were carried out; partial confirmation of the original factorial structure of the instrument was obtained, which revealed the following factorial structures. Subscale (1): promotion of cognitive and linguistic development, social skills, psychomotor skills, and pretend play and imitation; subscale (2): promotion of independence and self-esteem, provision of optimal frustration, social and emotional quality of the relationship, and absence of physical punishment; subscale (3): paternal involvement, low exposure to family conflict, low frequency of family conflict, relationship with the extended family, social support, diversity of experiences, low frequency of stressful events, and low parental perception of stress. The structure of the original instrument structure was partially confirmed, which was attributed to the characteristics of the sample. We stress the importance of the variability obtained in the evaluation of the families, as well as of adequate indicators of reliability in such evaluation. The new instrument could be used in public health to identify deficient family contexts and to design preventive interventions focused on parenting skills. Copyright © 2013 SESPAS.

    To investigate the feasibility of sonoelastography to show muscle stiffness in poststroke spasticity, as well as the relationship between sonoelastography findings and muscle architecture features and clinical spasticity scores in the spastic gastrocnemius. Cross-sectional study. University rehabilitation center. A total of 26 stroke patients with gastrocnemius muscle spasticity (≥1 using the Modified Ashworth Scale score). None. Sonoelastography parameters (elasticity index and elasticity ratio) and muscle architecture features (muscle fascicle length, fascicle pennation angle, muscle thickness and compressibility) were measured from the medial and lateral gastrocnemius muscle on both the affected and unaffected sides. Both the elasticity index and elasticity ratio on the affected side were significantly increased in both the medial and lateral gastrocnemius compared with those on the unaffected side (P .05). Sonoelastographic findings showed a weak negative correlation with compressibility and a weak positive correlation with the Modified Ashworth Scale score in the spastic medial gastrocnemius. It was found to be feasible to assess stiffness in spastic gastrocnemius muscles of stroke patients with sonoelastography. Further studies are needed to confirm the potential role of sonoelastography to help guide treatment of spasticity and its sequelae.

    Full Text Available This paper assesses the reality of corporate governance in Jordan. It identifies the framework of corporate governance, which has here been set into two dimensions – institutionalisations and regulations – and describes the five major principles of corporate governance. The study was carried out by interviews with key employees and the review of related laws and selected annual reports. The study found (1 basic shareholder rights were honoured in decision-making, except for large decisions such as major asset sales; (2 shareholders were not treated equitably in practice, although controllers sometimes took action and prohibited insider trading; (3 the role and rights of stakeholders in corporate governance were respected, and stakeholders had a number of legal protections, which were largely covered in Jordan's Company Law; (4 disclosure and transparency were observed to a large extent, although limited to quantity rather than quality, because Jordan has fully adopted IFRS and ISA and (5 boards largely fulfilled their responsibilities, as these are extensively defined by law and regulation.

    Full Text Available Abstract Background Lengthy questionnaires reduce data quality and impose a burden on respondents. Previous researchers proposed that a single item ("My future seems dark to me" and a 4-item component of the Beck's Hopelessness Scale (BHS can summarise most of the information the BHS provides. There is no clear indication of what BHS cutoff values are useful in identifying people with suicide tendency. Methods In a population-based study of Chinese people aged between 15 and 59 in Hong Kong, the Chinese version of the BHS and the Centre for Epidemiologic Studies – Depression scale were administered by trained interviewers and suicidal ideation and suicidal attempts were self-reported. Receiver operating characteristics curve analysis and regression analysis were used to compare the performance of the BHS and its components in identifying people with suicidality and depression. Smoothed level of suicidal tendency was assessed in relation to scores on the BHS and its component to identify thresholds. Results It is found that the 4-item component and, to a lesser extent, the single item of the BHS perform in ways similar to the BHS. There are non-linear relationship between suicidality and scores on the BHS and the 4-item component; cutoff values identified accordingly have sensitivity and specificity of about 65%. Conclusion The 4-item component is a useful alternative to the BHS. Shortening of psycho-social measurement scales should be considered in order to reduce burden on patients or respondents and to improve response rate.

    The use of integrated Hospital Information Systems is related with many benefits for the healthcare system, increasing the effectiveness of the provided services and assuring quality of care. Aim of this study is to investigate the types of Information Systems, the level of integration and the problems identified during the implementation phase, in three public hospitals. The above are expected to contribute to the understanding of the organizational, human resource and technical factors related with the successful implementation of a hospital IS. In order to investigate those elements, an assessment questionnaire was developed and completed by nine hospitals IT employees of the three hospitals. In addition, open interviews were organized with the same employees to further formulate an overall aspect, while in one hospital case, observation and discussion with four different categories of involved staff was undertaken. It was found that the implementation problems are mainly related with the underfunding, inadequate use of standards, lack of skilled IT experts, insufficiently trained personnel and users' reserve. The problems may be tackled with a supportive hospital administration committed to the successful implementation. The external contracting company working on its own, without any participation of the hospital IT department seems to be a failure recipe. It is evident that an active management support and skillful hospital IT employees, are expected to result to success stories during the implementation of integrated hospital information systems.

    The aim of this pilot study was to evaluate a new, non-invasive examination method using MRI for the quantification of the colonic transit time after oral administration of gadolinium-saline solution filled capsules. Healthy volunteers without previous or acute symptoms of gastrointestinal disorders were enrolled. After a 3-day diet for the standardization of gastrocolonic content the volunteers swallowed five Gd-DTPA/saline 0.9%-filledcapsules. Seven different concentrations of Gd-DTPA/saline 0.9% solution between 1:0 and 0:1 were tested in a dilution series. Following ingestion of capsules, coronal Flash T1 and True Fisp sequences using a 1.5 Tesla system were obtained at 0 h, 3 h, 6 h, 12 h, 24 h, 36 h and 60 h. Sequences were analyzed by two independent experts for locating the capsules. Overall colonic transit time was separately analyzed for both genders. Fifteen healthy volunteers (7 females, 8 males; mean age 34±13 years) were enrolled. The phantom study provided the best contrast in both the T1-and T2-weighted sequences defining a ratio of 1:10 for Gd-DTPA/saline 0.9% solution. The mean transit time accounted for 41±9 h in women and for 31±10 h in men. MRI is an adequate method for the assessment of colonic transit time offering the advantages of no exposure to radiation, short examination time, possible dynamic evaluation of the transit and the practicability in terms of a future adoption to clinical routine.

    Health care managers and personnel should be aware and literate of health information system in order to increase the efficiency and effectiveness in their organization. Since accurate, appropriate, precise, timely, valid information and interpretation of information is required and is the basis for policy planning and decision making in various levels of the organization. This study was conducted to assess the district health information system evolution in Iran according to WHO framework. This research is an applied, descriptive cross sectional study, in which a total of twelve urban and eight rural facilities, and the district health center at Falavarjan region were surveyed by using a questionnaire with 334 items. Content and constructive validity and reliability of the questionnaire were confirmed with correlation coefficient of 0.99. Obtained data were analyzed with SPSS 16 software and descriptive statistics were used to examine measures of WHO compliance. The analysis of data revealed that the mean score of compliance of district health information system framework was 35.75 percent. The maximum score of compliance with district health information system belonged to the data collection process (70 percent). The minimum score of compliance with district health information system belonged to information based decision making process with a score of 10 percent. District Health Information System Criteria in Isfahan province do not completely comply with WHO framework. Consequently, it seems that health system managers engaged with underlying policy and decision making processes at district health level should try to restructure and decentralize district health information system and develop training management programs for their managers.

    There is growing evidence to show the effectiveness of physical exercise for multiple sclerosis (MS) patients. Aim of this study was to evaluate aerobic capacity, strength, balance, and the rate of perceived exertion (RPE) after exercise, in ambulatory patients with mild MS and matched control healthy participants. Seventeen MS patients aged 48.09 ± 10.0 years, with mild MS disability (Expanded Disability Status Scale: EDSS 1.5 to 4.5) and 10 healthy sedentary age matched (41.9 ± 11.2 years) subjects volunteered for the study. MS patients underwent medical examination with resting electrocardiogram, arterial blood pressure, EDSS, and Modified Fatigue Impact Scale-MFIS. Both groups also underwent physical assessment with the Berg Balance Scale(,) test (Berg), Six Minutes Walking Test (6MWT), maximal isometric voluntary contraction (MIVC) of forearm, lower limb, shoulder strength test, and the Borg 10-point scale test. The one-way ANOVA showed significant differences for MFIS (F1.19=9.420; p<0.01), Berg (F1.19=13.125; p<0.01), handgrip MIVC (F1.19=4.567; p<0.05), lower limbs MIVC (F1.19=7.429; p<0.01), and 6MWT (F1.19=28.061; p<0.01) between groups. EDSS, Berg test and Borg scores explained 80% of 6MWT variation. Mild grade EDSS patients exhibited impaired balance, muscle strength, and low self pace-6MWT scores, whereas RPE response after the exercise was similar to that of sedentary individuals. Both groups showed similar global physiological adjustments to exercise. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Objectives: Spatial assessment of traffic noise pollution intensity will provide urban planners with approximate estimation of citizens exposure to impermissible sound levels. They could identify critical noise pollution areas wherein noise barriers should be embedded. The present study aims at using the Geographic Information System (GIS to assess spatial changes in traffic noise pollution in Tehran, the capital of Iran, and the largest city in the Middle East. Material and Methods: For this purpose, while measuring equivalent sound levels at different time periods of a day and different days of a week in District 14 of Tehran, wherein there are highways and busy streets, the geographic coordination of the measurement points was recorded at the stations. The obtained results indicated that the equivalent sound level did not show a statistically significant difference between weekdays, and morning, afternoon and evening hours as well as time intervals of 10 min, 15 min and 30 min. Then, 91 stations were selected in the target area and equivalent sound level was measured for each station on 3 occasions of the morning (7:00–9:00 a.m., afternoon (12.00–3:00 p.m. and evening (5:00–8:00 p.m. on Saturdays to Wednesdays. Results: As the results suggest, the maximum equivalent sound level (Leq was reported from Basij Highway, which is a very important connecting thoroughfare in the district, and was equal to 84.2 dB(A, while the minimum equivalent sound level (Leq, measured in the Fajr Hospital, was equal to 59.9 dB(A.

    Along the Pacific Northwest coast, much of the estuarine habitat has been diked over the last century for agricultural land use, residential and commercial development, and transportation corridors. As a result, many of the ecological processes and functions have been disrupted. To protect coastal habitats that are vital to aquatic species, many restoration projects are currently underway to restore the estuarine and coastal ecosystems through dike breaches, setbacks, and removals. Information on physical processes and hydrodynamic conditions are critical for the assessment of the success of restoration actions. Restoration of a 160- acre property at the mouth of the Stillaguamish River in Puget Sound has been proposed. The goal is to restore native tidal habitats and estuary-scale ecological processes by removing the dike. In this study, a three-dimensional hydrodynamic model was developed for the Stillaguamish River estuary to simulate estuarine processes. The model was calibrated to observed tide, current, and salinity data for existing conditions and applied to simulate the hydrodynamic responses to two restoration alternatives. Responses were evaluated at the scale of the restoration footprint. Model data was combined with biophysical data to predict habitat responses at the site. Results showed that the proposed dike removal would result in desired tidal flushing and conditions that would support four habitat types on the restoration footprint. At the estuary scale, restoration would substantially increase the proportion of area flushed with freshwater (< 5 ppt) at flood tide. Potential implications of predicted changes in salinity and flow dynamics are discussed relative to the distribution of tidal marsh habitat.

    Cultural competence is widely considered a cornerstone of patient care. Efforts to improve military cultural competency have recently gained national attention. Assessment of cultural competence is a critical component to this effort, but no assessment of military cultural competence currently exists. An assessment of military cultural competence (AMCC) was created through broad input and consensus. Careful review of previous cultural competency assessment designs and analysis techniques was considered. The AMCC was organized into three sections: skills, attitudes, and knowledge. In addition to gathering data to determine absolute responses from groups with different exposure levels to the military (direct, indirect, and none), paired questions were utilized to assess relative competencies between military culture and culture in general. Piloting of the AMCC revealed significant differences between military exposure groups. Specifically, those with personal military exposure were more likely to be in absolute agreement that the military is a culture, were more likely to screen for military culture, and had increased knowledge of military culture compared to those with no military exposure. Relative differences were more informative. For example, all groups were less likely to agree that their personal culture could be at odds with military culture as compared to other cultures. Such perceptions could hinder asking difficult questions and thus undermine care. The AMCC is a model for the measurement of the skills, attitudes, and knowledge related to military cultural competence. With further validity testing, the AMCC will be helpful in the critical task of measuring outcomes in ongoing efforts to improve military cultural competence. The novel approach of assessing variance appears to reduce bias and may also be helpful in the design of other cultural competency assessments.

    Ergonomics has gained attention and take into consideration by the workers in the different fields of works recently. It has given a huge impact on the workers comfort which directly affects the work efficiency and productivity. The workers have claimed to suffer from the painful postures and injuries in their workplace. Musculoskeletal disorders (MSDs) is the most common problem frequently reported by the workers. This problem occurs due to the lack of knowledge and alertness from the workers to the ergonomic in their surroundings. This paper intends to review the approaches and instruments used by the previous works of the researchers in the evaluation of the ergonomics. The two main assessment methods often used for ergonomic evaluation are Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA). Popular devices are Inertial Measurement Units (IMU) and Microsoft Kinect.

The popularity of PGIS is evident in the various studies and contexts in which it has been utilised. These include studies in risk assessment, land administration, resource management, crime mapping and urban design to mention but a few. Despite the popularity of PGIS as a body of research, little has been done in the analysis of the quality of PGIS information. The study investigated the use of data quality criteria commonly used in traditional GIS systems and shows that it is possible to apply the criteria used in traditional GIS to PGIS. It provides a starting point for PGIS studies to assess the quality of the product. Notably, this a reflective exercise on one case study, but the methodologies used in this study have been replicated in many others undertaken by Community Based Organisations as well as Non-Governmental Organisations. Therefore the findings are relevant to such projects.

    Gart, Natalie; Zamora, Irina; Williams, Marian E

    2016-07-01

    Therapeutic Assessment (TA; S.E. Finn & M.E. Tonsager, 1997; J.D. Smith, 2010) is a collaborative, semistructured model that encourages self-discovery and meaning-making through the use of assessment as an intervention approach. This model shares core strategies with infant mental health assessment, including close collaboration with parents and caregivers, active participation of the family, a focus on developing new family stories and increasing parents' understanding of their child, and reducing isolation and increasing hope through the assessment process. The intersection of these two theoretical approaches is explored, using case studies of three infants/young children and their families to illustrate the application of TA to infant mental health. The case of an 18-month-old girl whose parents fear that she has bipolar disorder illustrates the core principles of the TA model, highlighting the use of assessment intervention sessions and the clinical approach to preparing assessment feedback. The second case follows an infant with a rare genetic syndrome from ages 2 to 24 months, focusing on the assessor-parent relationship and the importance of a developmental perspective. Finally, assessment of a 3-year-old boy illustrates the development and use of a fable as a tool to provide feedback to a young child about assessment findings and recommendations. © 2016 Michigan Association for Infant Mental Health.

    Extensive discussions have taken place in recent year regarding impact assessment - what is it and how can we do it? It is especially intriguing in this modern era where non-traditional warfare has caused either information overload or limited understanding of adversary doctrines. This work provides a methodical discussion of key elements for the broad definition of impact assessment (IA). The discussion will start with a process flow involving components related to IA. Two key functional components, impact estimation and threat projection, are compared and illustrated in detail. These details include a discussion of when to model red and blue knowledge. Algorithmic approaches will be discussed, augmented with lessons learned from our IA development for cyber situation awareness. This paper aims at providing the community with a systematic understanding of IA and its open issues with specific examples.

    2006-01-01

    One of the key tasks in the periodic safety review (PSR) of nuclear power plant is to assess the aging management of structures, systems and components (SSC). The evaluation can be categorized by two parts, passive and active components. Unlike the passive components, active components are periodically maintained and replaced with new components, so the evaluation of aging mechanism of the passive components such as erosion, corrosion is not applicable to the evaluation of active components of nuclear power plant. For active components, they will maintain capability to fulfill its design function if preventive maintenance effectiveness is proper. In this paper, the assessment based on the reliability and availability of the active components of the domestic nuclear power plants is examined

    2015-06-01

    As part of an ongoing investigation of students' learning in first semester upper-division quantum mechanics, we needed a high-quality conceptual assessment instrument for comparing outcomes of different curricular approaches. The process of developing such a tool started with converting a preliminary version of a 14-item open-ended quantum mechanics assessment tool (QMAT) to a multiple-choice (MC) format. Further question refinement, development of effective distractors, adding new questions, and robust statistical analysis has led to a 31-item quantum mechanics concept assessment (QMCA) test. The QMCA is used as post-test only to assess students' knowledge about five main topics of quantum measurement: the time-independent Schrödinger equation, wave functions and boundary conditions, time evolution, and probability density. During two years of testing and refinement, the QMCA has been given in alpha (N =61 ) and beta versions (N =263 ) to students in upper division quantum mechanics courses at 11 different institutions with an average post-test score of 54%. By allowing for comparisons of student learning across different populations and institutions, the QMCA provides instructors and researchers a more standard measure of effectiveness of different curricula or teaching strategies on student conceptual understanding of quantum mechanics. In this paper, we discuss the construction of effective distractors and the use of student interviews and expert feedback to revise and validate both questions and distractors. We include the results of common statistical tests of reliability and validity, which suggest the instrument is presently in a stable, usable, and promising form.

    Full Text Available The natural environment affects the construction of desert highways. Conversely, highway construction affects the natural environment and puts the ecological environment at a disadvantage. To satisfy the variety and hierarchy of desert highway construction and discover the spatio-temporal distribution of the natural environment and its effect on highway construction engineering, an assessment of the natural regional divisions of desert highways in China is carried out for the first time. Based on the general principles and method for the natural region division, the principles, method and index system for desert highway assessment is put forward by combining the desert highway construction features and the azonal differentiation law. The index system combines the dominant indicator and four auxiliary indicators. The dominant indicator is defined by the desert’s comprehensive state index and the auxiliary indicators include the sand dune height, the blown sand strength, the vegetation coverage ratio and the annual average temperature difference. First the region is divided according to the dominant indicator. Then the region boundaries are amended according to the four auxiliary indicators. Finally the natural region division map for desert highway assessment is presented. The Chinese desert highways can be divided into three sections: the east medium effect region, the middle medium-severe effect region, and the west slight-medium effect region. The natural region division map effectively paves the way for the route planning, design, construction, maintenance and ongoing management of desert highways, and further helps environmental protection.

  3. Review of Chinese Environmental Risk Assessment Regulations and Case Studies

    2012-01-01

    Environmental risk assessment is an essential step in the development of solutions for pollution problems and new environmental regulations. An assessment system for environmental risks has been developed in China in recent decades. However, many of the Chinese technical guidelines, standards, and regulations were directly adapted from those of developed countries, and were not based on the Chinese environmental and socioeconomic context. Although existing environmental regulations for pollutants are usually obtained by extrapolations from high-dose toxicological data to low-dose scenarios using linear-non-threshold (LNT) models, toxicologists have argued that J-shaped or inverse J-shaped curves may dominate the dose–response relationships for environmental pollutants at low doses because low exposures stimulate biological protective mechanisms that are ineffective at higher doses. The costs of regulations based on LNT and J-shaped models could therefore be dramatically different. Since economic factors strongly affect the decision-making process, particularly for developing countries, it is time to strengthen basic research to provide more scientific support for Chinese environmental regulations. In this paper, we summarize current Chinese environmental policies and standards and the application of environmental risk assessment in China, and recommend a more scientific approach to the development of Chinese regulations.

    Full Text Available Health care policy background: Findings from scientific studies form the basis for evidence-based health policy decisions. Scientific background: Quality assessments to evaluate the credibility of study results are an essential part of health technology assessment reports and systematic reviews. Quality assessment tools (QAT for assessing the study quality examine to what extent study results are systematically distorted by confounding or bias (internal validity. The tools can be divided into checklists, scales and component ratings. Research questions: What QAT are available to assess the quality of interventional studies or studies in the field of health economics, how do they differ from each other and what conclusions can be drawn from these results for quality assessments? Methods: A systematic search of relevant databases from 1988 onwards is done, supplemented by screening of the references, of the HTA reports of the German Agency for Health Technology Assessment (DAHTA and an internet search. The selection of relevant literature, the data extraction and the quality assessment are carried out by two independent reviewers. The substantive elements of the QAT are extracted using a modified criteria list consisting of items and domains specific to randomized trials, observational studies, diagnostic studies, systematic reviews and health economic studies. Based on the number of covered items and domains, more and less comprehensive QAT are distinguished. In order to exchange experiences regarding problems in the practical application of tools, a workshop is hosted. Results: A total of eight systematic methodological reviews is identified as well as 147 QAT: 15 for systematic reviews, 80 for randomized trials, 30 for observational studies, 17 for diagnostic studies and 22 for health economic studies. The tools vary considerably with regard to the content, the performance and quality of operationalisation. Some tools do not only include the

    Statistical parametric mapping (SPM) has become the technique of choice to statistically evaluate positron emission tomography (PET), functional magnetic resonance imaging (fMRI), and single photon emission computed tomography (SPECT) functional brain studies. Nevertheless, only a few methodological studies have been carried out to assess the performance of SPM in SPECT. The aim of this paper was to study the performance of SPM in detecting changes in regional cerebral blood flow (rCBF) in hypo- and hyperperfused areas in brain SPECT studies. The paper seeks to determine the relationship between the group size and the rCBF changes, and the influence of the correction for degradations. The assessment was carried out using simulated brain SPECT studies. Projections were obtained with Monte Carlo techniques, and a fan-beam collimator was considered in the simulation process. Reconstruction was performed by using the ordered subsets expectation maximization (OSEM) algorithm with and without compensation for attenuation, scattering, and spatial variant collimator response. Significance probability maps were obtained with SPM2 by using a one-tailed two-sample t-test. A bootstrap resampling approach was used to determine the sample size for SPM to detect the between-group differences. Our findings show that the correction for degradations results in a diminution of the sample size, which is more significant for small regions and low-activation factors. Differences in sample size were found between hypo- and hyperperfusion. These differences were larger for small regions and low-activation factors, and when no corrections were included in the reconstruction algorithm.

    Traditional deterministic approaches for small signal stability assessment (SSSA) are unable to properly reflect the existing uncertainties in real power systems. Hence, the probabilistic analysis of small signal stability (SSS) is attracting more attention by power system engineers. This paper discusses and compares two probabilistic methodologies for SSSA, which are based on the two point estimation method and the so-called Monte Carlo method, respectively. The comparisons are based on the results obtained for several power systems of different sizes and with different SSS performance. It is demonstrated that although with an analytical approach the amount of computation of probabilistic SSSA can be reduced, the different degrees of approximations that are adopted, lead to deceptive results. Conversely, Monte Carlo based probabilistic SSSA can be carried out with reasonable computational effort while holding satisfactory estimation precision. (author)

    Full Text Available Abstract Background Evaluation of the potential effectiveness of a programme’s objectives (health or otherwise is important in demonstrating how programmes work. However, evaluations are expensive and can focus on unrealistic outcomes not grounded in strong theory, especially where there is pressure to show effectiveness. The aim of this research was to demonstrate that the evaluability assessment (a cost-effective pre-evaluation tool that primarily gives quick, constructive feedback can be used to help develop programme and outcome objectives to improve programmes while they run and to assist in producing more effective evaluations. This was done using the example of a community development programme aiming to improve health and reduce health inequalities in its target population. Methods The setting was Glasgow, Scotland, UK and focused on the Health Issues in the Community programme. Data were collected from documents and nine individual stakeholder interviews. Thematic analysis and a realist approach were used to analyse both datasets and, in conjunction with a workshop with stakeholders, produce a logic model of the programme theory and related evaluation options to explore further. Results Five main themes emerged from the analysis: History; Framework; Structure and Delivery of the Course; Theory of Action; and Barriers to Delivery and Successful Outcomes. These themes aided in drafting the logic model which revealed they key programme activities (e.g. facilitating group learning and 23 potential outcomes. The majority of these outcomes (16 were deemed to be short-term outcomes (more easily measured within the timeframe of an individual being involved in the programme e.g. increased self-esteem or awareness of individual/community health. The remaining 6 outcomes were deemed longer-term and included outcomes such as increased social capital and individual mental health and wellbeing. Conclusions We have shown that the evaluability

    Full Text Available Final goal of the study is to estimate the cost-e ectiveness of electrochemotherapy for the tre- atment of basal-cell carcinoma and skin melanoma. Paper consists of two parts: the first part presents basic principles and concepts of health technology assessment and cost-e ectiveness analysis, and the second part reports an early cost-e ectiveness analysis of electrochemothe - rapy for the treatment of basal-cell carcinoma and skin melanoma that we are developing. Few cost-e ectiveness analyses of electrochemotherapy have already been done, but with a lack of information about intervention e ectiveness in terms of quality of life, which may result in inac- curate or even inadequate conclusions. In order to obtain the most realistic results, two general Markov models and their reduced versions for initial calculations are presented. The models were designed specifically to assess electrochemotherapy of basal-cell carcinoma and skin me- lanoma. Also, data required for successful calculations have been identified, some of which are missing and will be collected within di erent studies which are still under way, including rando- mized control trials. Additionally, recommendations for data collection process and follow-up reporting are made. With this paper we want to raise awareness about the importance of nume- ric quality of life reporting and usefulness/meaning of EQ-5D questionnaire that might not be self-evident at first sight, but are crucial for cost-e ectiveness analysis.

    The intention of this study was to compare the efficacy of eyelet wiring and direct interdental (Gilmer) wiring for achieving intermaxillary fixation (IMF). This study was a prospective randomized clinical trial. The study sample was derived from the population of patients who underwent IMF at the Department of Oral and Maxillofacial Surgery, Sharad Pawar Dental College, Wardha, India, between October 2008 and September 2010. The time required for placement and removal (in minutes) was compared between the eyelet wiring and direct interdental wiring techniques. Postoperative stability after achieving IMF was analyzed in the 2 groups. The plaque accumulation in both groups was evaluated using the Turesky-Gilmore-Glickman modification of the Quigley-Hein plaque index. Complications in the form of soft tissue injury, glove puncture, and trauma to the operator's finger were also recorded. Statistical analysis was performed with SPSS statistical software for Windows, version 8.0 (SPSS, Chicago, IL) using the χ(2) test and Student t test. The mean working time for placement and removal of eyelet wiring (group I) was 18.00 minutes and 9.67 minutes, respectively. For direct interdental wiring (group II), it was 30.50 minutes and 23.12 minutes, respectively. The mean plaque index values were 1.78 and 2.54 for groups I and II, respectively, which signifies a higher plaque deposition in group II. No occlusal disturbance was seen in either group. The incidences of glove perforation, soft tissue trauma, and trauma to the operator's finger were higher in group II. Eyelet wiring is preferable to direct interdental wiring as evidenced by fewer complications, and requires a shorter operating time in patients with minimally displaced fractures.

  4. Physician assessments of drug seeking behavior: A mixed methods study.

    Directory of Open Access Journals (Sweden)

    Michael A Fischer

    Full Text Available Pain complaints are common, but clinicians are increasingly concerned about overuse of opioid pain medications. This may lead patients with actual pain to be stigmatized as "drug-seeking," or attempting to obtain medications they do not require medically. We assessed whether patient requests for specific opioid pain medication would lead physicians to classify them as drug-seeking and change management decisions.Mixed-methods analysis of interviews with 192 office-based primary care physicians after viewing video vignettes depicting patients presenting with back pain. For each presentation physicians were randomly assigned to see either an active request for a specific medication or a more general request for help with pain. The main outcome was assignment by the physician of "drug-seeking" as a potential diagnosis among patients presenting with back pain. Additional outcomes included other actions the physician would take and whether the physician would prescribe the medication requested. A potential diagnosis of drug-seeking behavior was included by 21% of physicians seeing a specific request for oxycodone vs. 3% for a general request for help with back pain(p<0.001. In multivariable models an active request was most strongly associated with a physician-assigned diagnosis of drug-seeking behavior(OR 8.10; 95% CI 2.11-31.15;p = 0.002; other major patient and physician characteristics, including gender and race, did not have strong associations with drug-seeking diagnosis. Physicians described short courses of opioid medications as a strategy for managing patients with pain while avoiding opioid overuse.When patients make a specific request for opioid pain medication, physicians are far more likely to suspect that they are drug-seeking. Physician suspicion of drug-seeking behavior did not vary by patient characteristics, including gender and race. The strategies used to assess patients further varied widely. These findings indicate a need for

  5. Tissue quality assessment using a novel direct elasticity assessment device (the E-finger: a cadaveric study of prostatectomy dissection.

    Directory of Open Access Journals (Sweden)

    Daniel W Good

    Full Text Available Minimally invasive radical prostatectomy (RP (robotic and laparoscopic, have brought improvements in the outcomes of RP due to improved views and increased degrees of freedom of surgical devices. Robotic and laparoscopic surgeries do not incorporate haptic feedback, which may result in complications secondary to inadequate tissue dissection (causing positive surgical margins, rhabdosphincter damage, etc. We developed a micro-engineered device (6 mm2 sized [E-finger] capable of quantitative elasticity assessment, with amplitude ratio, mean ratio and phase lag representing this. The aim was to assess the utility of the device in differentiating peri-prostatic tissue types in order to guide prostate dissection.Two embalmed and 2 fresh frozen cadavers were used in the study. Baseline elasticity values were assessed in bladder, prostate and rhabdosphincter of pre-dissected embalmed cadavers using the micro-engineered device. A measurement grid was created to span from the bladder, across the prostate and onto the rhabdosphincter of fresh frozen cadavers to enable a systematic quantitative elasticity assessment of the entire area by 2 independent assessors. Tissue was sectioned along each row of elasticity measurement points, and stained with haematoxylin and eosin (H&E. Image analysis was performed with Image Pro Premier to determine the histology at each measurement point.Statistically significant differences in elasticity were identified between bladder, prostate and sphincter in both embalmed and fresh frozen cadavers (p = < 0.001. Intra-class correlation (ICC reliability tests showed good reliability (average ICC = 0.851. Sensitivity and specificity for tissue identification was 77% and 70% respectively to a resolution of 6 mm2.This cadaveric study has evaluated the ability of our elasticity assessment device to differentiate bladder, prostate and rhabdosphincter to a resolution of 6 mm2. The results provide useful data for which to continue to

    Despite the recent expansion of clinical studies allocated to Brazil, the delay of local regulatory deadlines directly impacts their completion. This article examines the allocation process of clinical studies to Brazil in comparison with other countries, as well as the financial impact of studies not completed due to interruption caused by the delay in the regulatory process. The allocation processes of studies were compared in nine countries with similar stages of economic development and countries in Latin America using the websites http://data.worldbank.org/data-catalog/GDP-rankings-table and http://worldpopulationreview.com and clinicaltrials.gov, comprising 185 countries. The 46 studies sponsored by the pharmaceutical industry underwent an analysis of the regulatory review process. 46 studies sponsored by the industry and submitted in the country between June 2007 and June 2013 were analyzed; 18 (39%) were discontinued due to the delay in obtaining the necessary approvals. For the approved studies, patient recruitment began an average of 11 months after the other countries. It is estimated that 530 Brazilians patients did not have the opportunity to participate in these studies. Financial losses were to the order of 14.6 million dollars for the country, including patient, medication and supplies costs, and expenses. Brazil has enormous potential for the realization of clinical studies. Researchers, associations of disabled people and patients with chronic diseases, sponsors and the authorities must work together to develop an approval process that is efficient, predictable and, most of all, transparent. The current regulatory environment must and can be improved and optimized in order to result in tangible benefits for patients, society and the country's scientific development.

    2018-04-01

    Despite the fact that surface energy is a fundamental quantity in understanding surface structure of nanoparticle, the results of experimental measurements and theoretical calculations for the surface energy of pure Pt show a wide range of scattering. It is necessary to further ensure the surface energy of Pt to find the equilibrium shape and atomic configuration in Pt bimetallic nanoparticles accurately. In this article, we critically assess and optimize the Pt surface energy using a semi-empirical atomistic approach based on the second nearest-neighbor modified embedded-atom method interatomic potential. That is, the interatomic potential of pure Pt was adjusted in a way that the surface segregation tendency in a wide range of Pt binary alloys is reproduced in accordance with experimental information. The final optimized Pt surface energy (mJ/m2) is 2036 for (100) surface, 2106 for (110) surface, and 1502 for (111) surface. The potential can be utilized to find the equilibrium shape and atomic configuration of Pt bimetallic nanoparticles more accurately.

    An ecological risk assessment was conducted for 10 sites at a remote location that has unique biological resources. Chemicals of concern included petroleum, metals, polychlorinated biphenyls, and dioxins and furans. Risks to 23 species of mammals and birds were evaluated by using toxicity reference values and a hazard quotient approach analogous to the US Environmental Protection Agency's (USEPA's) approach for evaluating noncarcinogenic human health effects. Risks to fish and aquatic invertebrates were evaluated using risk-based concentrations for water analogous to the USEPA's water quality criteria. Risks to plants were evaluated using risk-based concentrations for soil. Toxicity reference values and risk-based concentrations were developed by applying uncertainty factors to the highest quality toxicity data available in the literature. Intake rates for wildlife were obtained from the USEPA's wildlife exposure factors handbook, or were estimated using allometric equations. The sizes of wildlife home ranges were compared with the size of each site to determine species- and site-specific exposure frequencies. Indicator chemicals were selected to represent the chemical and toxicological characteristics of petroleum fractions. The species most often at risk were found to be fish and aquatic invertebrates, as well as small-bodied, ground-dwelling or ground-feeding wildlife

    Bubbico, Roberto; Marchini, Mauro

    2008-07-15

    In the present paper, an accident occurred during a liquefied petroleum gas (LPG) tank filling activity has been taken into consideration. During the transfer of LPG from the source road tank car to the receiving fixed storage vessel, an accidental release of LPG gave rise to different final consequences ranging from a pool fire, to a fireball and to the catastrophic rupture of the tank with successive explosion of its contents. The sequence of events has been investigated by using some of the consequence calculation models most commonly adopted in risk analysis and accident investigation. On one hand, this allows to better understand the link between the various events of the accident. On the other hand, a comparison between the results of the calculations and the damages actually observed after the accident, allows to check the accuracy of the prediction models and to critically assess their validity. In particular, it was shown that the largest uncertainty is associated with the calculation of the energy involved in the physical expansion of the fluid (both liquid and vapor) after the catastrophic rupture of the tank.

    Students tend to postpone preparation for a test until the test is imminent, which raises various risks associated with 'cramming' behaviours, including that for suboptimal learning. Cumulative assessment utilises spaced testing to stimulate students to study more frequently and to prevent procrastination. This randomised controlled study investigated how cumulative assessment affects time spent on self-study and test performance compared with end-of-course assessment. A total of 78 undergraduate medical students in a Year 2 pre-clinical course were randomly assigned to either of two conditions. Students in the cumulative assessment condition were assessed in weeks 4, 8 and 10. Students in the end-of-course assessment condition were assessed in week 10 only. Each week, students reported the number of hours they spent on self-study. Students in the cumulative assessment condition (n = 25) spent significantly more time on self-study than students in the end-of-course assessment condition (n = 37) in all weeks of the course except weeks 5, 9 and 10. Overall, the cumulative assessment group spent 69 hours more on self-study during the course than did the control group, although the control group spent 7 hours more in studying during the final week of the course than did the cumulative assessment group. Students in the cumulative assessment condition scored slightly higher on questions concerning the content of the last part of the course. Cumulative assessment encourages students to distribute their learning activities over a course, which leaves them more opportunity to study the content of the last part of the course prior to the final examination. There was no evidence for a short-term effect of cumulative assessment on overall knowledge gain. We hypothesise that larger positive effects might be found if retention were to be measured in the long term. © 2015 John Wiley & Sons Ltd.

  1. Assessing the quality of reporting of observational studies in cancer.

    Papathanasiou, Afroditi A; Zintzaras, Elias

    2010-01-01

    The vast majority of epidemiological studies in cancer are observational. However, inadequate reporting of the published observational studies (OS) may restrict the generalizability and credibility of study results. The aim of this study was to evaluate the reporting quality of OS concerning cancer. PubMed was searched for systematic reviews (SRs) of OS involving cancer published from January 2008 through February 2009. The citations provided in the SRs were evaluated for their reporting quality according to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement, a checklist of items that are considered essential for good reporting of OS. The evaluation was focused on 25 methodological items/sub-items. The effect of journals' ranking in quality of reporting was also evaluated. The search identified 244 eligible OS included in seven SRs. Nine items/sub-items were reported by more than 90% of studies and 16 items/sub-items were reported by more than 70%. Some essential methodological aspects of OS (such as matching, absolute risks, missing data and flow diagram) were underreported. Significant differences were found among the seven SRs in the majority of the items. High and lower ranked journals were different only in reporting of results estimates and precision. The quality of reporting in OS in cancer was considered satisfactory, although certain items were underreported. Further improvement of reporting may enhance the validity of observational research.

    This article describes the background and design of the third School Nutrition Dietary Assessment Study (SNDA-III). SNDA-III is a nationally representative cross-sectional study of the National School Lunch Program and the School Breakfast Program in 2005. The three-stage sample design allowed description of district and school food environments and policies, analysis of foods and nutrients in school lunches and breakfasts, and assessment of the role of school meals and competitive foods in students' diets. Surveys of district and school staff were by telephone or in person; school menu data were collected in a mail survey with telephone assistance; and student and parent interviews were conducted in person and in school, except that parents of secondary-school students were interviewed by telephone. Student interviews included a 24-hour dietary recall, as well as measurement of height and weight. Response rates were 83% for districts, 95% for schools, and 63% for students, whose participation was constrained by consent issues and school schedules. Data were collected from 130 public school food authorities (districts that offer federally subsidized school meals), 398 schools within those districts, and 2,314 public-school students in grades 1 through 12 in these schools. Of the 2,314 students, a random subset of 666 (29%) completed a second recall to permit estimation of usual nutrient intake distributions. Descriptive tabulations were used to summarize the background characteristics of schools and students and most study outcomes. Multivariate regression models and propensity score matching were used to compare the nutrient intakes of school meal participants and nonparticipants. SNDA-III data provide a rich resource for examining interactions among the school meal programs, the school food environment, students' diets, and child obesity. Subsequent articles in this Supplement present analyses in all these areas.

    Spin has been defined previously as "specific reporting that could distort the interpretation of results and mislead readers." The purpose of this study was to determine the frequency and extent of misrepresentation of results in robotic colorectal surgery. Publications referenced in MEDLINE or EMBASE between 1992 and 2014 were included in this study. Studies comparing robotic colorectal surgery with other techniques with a nonsignificant difference in the primary outcome(s) were included. Interventions included robotic versus alternative techniques. Frequency, strategy, and extent of spin, as previously defined, were the main outcome measures : A total of 38 studies (including 24,303 patients) were identified for inclusion in this study. Evidence of spin was found in 82% of studies. The most common form of spin was concluding equivalence between surgical techniques based on nonsignificant differences (76% of abstracts and 71% of conclusions). Claiming improved benefits, despite nonsignificance, was also commonly observed (26% of abstracts and 45% of conclusions). Because of the small sample size, we did not find evidence of an association between spin and study design, type of funding, publication year, or study size. Acknowledging the equivocal nature of the study happened rarely (47% of abstracts and 34% of conclusions). The absence of spin predicted whether authors acknowledged equivocal results (p = 0.02). A total of 50% of studies did not disclose whether they received funding, whereas 39% of studies failed to state whether a conflict of interest existed. A limited number of randomized controlled trials were available. Spin occurred in >80% of included studies. Many studies concluded that robotic surgery was as safe as more traditional techniques, despite small sample sizes and limited follow-up. Authors often failed to recognize the difference between nonsignificance and equivalence. Failure to disclose financial relationships, which could represent

    1995-01-01

    The ARIES tokamak designs have incorporated environmental and safety constraints in the design from the beginning. Low activation materials such as SiC or SiC composites, vanadium alloy, and modified HT-9 ferritic steel were utilized as the main structures in ARIES-IV, II, and III, respectively. All designs employ D-T fuel cycles except ARIES-III which is D- 3 He fuelled. An overall tritium breeding ratio of 1.12 seems adequate for ARIES-II and IV. The Li 2 O breeder requires a beryllium multiplier to achieve T self-sufficiency in the ARIES-IV design while the lithium has the ability to breed sufficient T in ARIES-II without a multiplier. Radiation damage concerns for the structures are the burn-up of the SiC and SiC composites and the atomic displacement in the vanadium. The first wall and blanket require frequent replacement (every 3-4 years) during reactor operation. The end-of-life fluences are 16.5MW yearsm -2 and 13MW yearsm -2 based on the 200dpa and 3% burn-up limits for the V and SiC structures respectively. Because of the lower neutron production, the ARIES-III first wall and shield are permanent components and require no replacement over the plant lifetime. A variety of shield options was examined and the ability of various materials to protect the magnets was assessed. At least 1.2m and 1.4m of inboard blanket-shield are required for magnet protection in ARIES-II and ARIES-IV respectively. The lack of T breeding and the lower wall loading result in a much thinner shield (0.65m) for ARIES-III. (orig.)

    After an earthquake, the fire risk of petrochemistry enterprises is higher than that of other enterprises as it involves production processes with inflammable and explosive characteristics. Using Chinese petrochemical enterprises as the research object, this paper uses a literature review and case summaries to study, amongst others, the classification of petrochemical enterprises, the proportion of daily fires, and fire loss ratio. This paper builds a fire following earthquake risk assessment model of petrochemical enterprises based on a previous earthquake fire hazard model, and the earthquake loss prediction assessment method, calculates the expected loss of the fire following earthquake in various counties and draws a risk map. Moreover, this research identifies high-risk areas, concentrating on the Beijing-Tianjin-Tangshan region, and Shandong, Jiangsu, and Zhejiang provinces. Differences in enterprise type produce different levels and distribution of petrochemical enterprises earthquake fire risk. Furthermore, areas at high risk of post-earthquake fires and with low levels of seismic fortification require extra attention to ensure appropriate mechanisms are in place.

    2017-06-01

    Selection of suitable municipal solid waste management (MSWM) options is one of the major challenges in urban areas of the developing countries. Success of MSWM requires accurate data of generation rate, composition and physico-chemical characteristics of solid wastes. Improper handling of solid waste can have significant environmental and aesthetical impacts. The present study proposes a new method (applicability index - P ik values) for identifying the most appropriate disposal option with the help of applicability values of Composting-C P , Incineration-I P and Landfill-L P for individual components of MSW based on the results of the physico-chemical analysis of the collected representative solid waste samples from the study area, Dhanbad, India. The mean values of moisture content, carbon, hydrogen, oxygen, nitrogen, sulfur, volatile organic carbon, fixed carbon, ash content, density and calorific values (CV) of individual components were used as input values in this process. Based on the proposed applicability index (P ik ), the highest P ik values were obtained for incineration (I P ) for plastics, polythene, paper, coconut shell, wood, cardboard, textile, thermocol (polystyrene), rubber, sugarcane bagasse, cow dung and leather wastes (I P  > C P  > L P ) due to high CV of these solid waste components; the highest P ik values were obtained for composting (C P ) of kitchen waste (C P  > I P  > L P ); and the highest P ik values for inert wastes were obtained for landfill option (L P  > I P  > C P ). The highest P ik value for a particular waste for a specific treatment option signifies that the waste is suitable for treatment/disposal using that option.

    To evaluate the cytotoxicity and genotoxicity activity of Euphorbia hirta (E. hirta) in MCF-7 cell line model using comet assay. The cytotoxicity of E. hirta extract was investigated by employing brine shrimp lethality assay and the genotoxicity of E. hirta was assessed by using Comet assay. Both toxicity tests exhibited significant toxicity result. In the comet assay, the E. hirta extract exhibited genotoxicity effects against MCF-7 DNA in a time-dependent manner by increasing mean percentage of DNA damage. The extract of E. hirta showed significant toxicity against brine shrimp with an LC₅₀ value of 620.382 µg/mL (24 h). Comparison with positive control potassium dichromate signifies that cytotoxicity exhibited by the methanol extract might have moderate activity. The present work confirmed the cytotoxicity and genotoxicity of E. hirta. However, the observed toxicity of E. hirta extracts needs to be confirmed in additional studies.

    Full Text Available Abstract: Nowadays in China, high school assessment is based solely on academic examination scores, which take the place of well-rounded assessments that should be given to students. The present assessment ignores the differences among individuals and goes against a people-oriented spirit; thus, it is not scientific. This one-sided assessment has caused many negative effects on students and society, and it is not beneficial to students’ well-being. The author performed a study on a formative assessment method using a Portfolio for keeping a record of English learning while growing up to change the present situation of students being tired of study due to low scores. The assessment allows students to understand that their low scores are not because they lack a gift for learning languages, but because they themselves think they lack the ability to learn a foreign language, which leads to their unwillingness to learn English (Ames 1992; Vispoel & Austin 1995. The research examines 122 year-11 senior middle school students’ views of the formative assessment method and their improvement in examination scores through the assessment over a period of one to two years. Qualitative and quantitative data were gathered via a questionnaire and interviews. All the data show and prove that the students who have been assessed using formative assessment enjoy going to school and have made more progress than those assessed using summative assessment. This assessment has been warmly welcomed by students, whether they are at a higher or a lower English level.

    2015-06-01

    Full Text Available The importance of autonomy learning is widely acknowledged in teaching English as a Foreign Language (EFL in Asian contexts. The present study attempted to report low proficiency level students’ autonomous vocabulary learning. The first part of the present study focused on exploring how learners perceived and experienced their autonomous vocabulary learning, with a questionnaire and group discussion applied to collect data. During the second part of the study, the data were discussed collaboratively by six teachers to identify the different approaches utilized by learners. Priorities included setting weekly goals, self-planning and self-monitoring the process of learning vocabulary. Results also revealed that a weak ‘top-down’ approach in implementing learner autonomy is inadequate. Teachers need to provide scaffolding skills tailored to learners’ context-specific needs, for which a strong ‘bottom-up’ approach is more appropriate in supporting autonomous learning. In this case, classroom time should be allocated to demonstrate the strategies and teachers should work collaboratively to develop resources and materials for learners’ autonomous vocabulary learning. The present study also addressed the need for establishing an effective intervention for supporting learner autonomy. Keywords: learner autonomy, vocabulary learning, self-plan, self-monitor

    The goal of this in vitro study was to identify the most suitable dye for endodontic dye leakage studies, which could be a further step towards standardisation. The root canals of 70 extracted, single-rooted human adult teeth were enlarged to apical size 50 using hand instruments. The teeth were divided into seven groups (n = 10 each), and all root canals were completely filled by injection with one of the following dyes: methylene blue 0.5% and 5%, blue ink, black ink, eosin 5%, basic fuchsin 0.5% and drawing ink. Transverse root sections from the coronal, middle and apical part of the roots were examined, and the percentage of the dentine penetrated by dye was evaluated by software-supported light microscopy. In addition, the range of particle size of drawing ink particles was evaluated. There were conspicuous differences in the relative dye penetration into the root dentine and the penetration behaviour in the different root sections (two-way ANOVA, both p < 0.0001). One dye (drawing ink) penetrated less into the root dentine compared with all the others (p <0.0001). The particle size of this agent (0.1-2 microm) corresponds best with the size range of a representative selection of 21 species of pathogenic endodontic bacteria. Compared to the other dyes tested, drawing ink appears to be superior for use in endodontic dye leakage studies. The penetration behaviour into the root dentine of all the other dyes tested might be one factor that limits the applicability of these dyes in dye leakage studies.

    Numerous organizations have published reports in recent years that investigate the ever changing world of electric vehicle (EV) technologies and their potential effects on society. Specifically, projections have been made on greenhouse gas (GHG) emissions associated with these vehicles and how they compare to conventional vehicles or hybrid electric vehicles (HEVs). Similar projections have been made on the volumes of oil that these vehicles can displace by consuming large amounts of grid electricity instead of petroleum-based fuels. Finally, the projected rate that these new vehicle fleets will enter the market varies significantly among organizations. New ideas, technologies, and possibilities are introduced often, and projected values are likely to be refined as industry announcements continue to be made. As a result, over time, a multitude of projections for GHG emissions, oil displacement, and market penetration associated with various EV technologies has resulted in a wide range of possible future outcomes. This leaves the reader with two key questions: (1) Why does such a collective range in projected values exist in these reports? (2) What assumptions have the greatest impact on the outcomes presented in these reports? Since it is impractical for an average reader to review and interpret all the various vehicle technology reports published to date, Sentech Inc. and the Oak Ridge National Laboratory have conducted a comparative study to make these interpretations. The primary objective of this comparative study is to present a snapshot of all major projections made on GHG emissions, oil displacement, or market penetration rates of EV technologies. From the extensive data found in relevant publications, the key assumptions that drive each report's analysis are identified and 'apples-to-apples' comparisons between all major report conclusions are attempted. The general approach that was taken in this comparative study is comprised of six primary

    Full Text Available Climate change is one of the major challenges facing humanity in the future and effect of climate change has been detrimental to agricultural industry. The aim of this study was to simulate the effects of climate change on the maturity period, leaf area index (LAI, biomass and grain yield of wheat under future climate change for the Sistan and Baluchestan region in Iran. For this purpose, two general circulation models HadCM3 and IPCM4 under three scenarios A1B, B1 and A2 in three time periods 2020, 2050 and 2080 were used. LARS-WG model was used for simulating climatic parameters for each period and CERES-Wheat model was used to simulate wheat growth. The results of model evaluation showed that LARS-WG had appropriate prediction for climatic parameters and simulation of stochastic growing season in future climate change conditions for the studied region. Wheat growing season period in all scenarios of climate change was reduced compared to the current situation. Possible reasons were the increase in temperature rate and the accelerated growth stages of wheat. This reduction in B1 scenario was less than A1B and A2 scenarios. Maximum wheat LAI in all scenarios, except scenario A1B in 2050, is decreased compared to the current situation. Yield and biological yield of wheat in both general circulation models under all scenarios and all times were reduced in comparison with current conditions and the lowest reduction was related to B1 scenario. In general, the results showed that wheat production in the future will be affected by climate change and will decrease in the studied region. To reduce these risks, the impact of climate change mitigation strategies and management systems for crop adaptation to climate change conditions should be considered.

  12. FINAL REPORT ON THE AQUATIC MERCURY ASSESSMENT STUDY

    Energy Technology Data Exchange (ETDEWEB)

    Halverson, N

    2008-09-30

    In February 2000, the United States Environmental Protection Agency (EPA) Region 4 issued a proposed Total Maximum Daily Load (TMDL) for total mercury in the middle and lower Savannah River. The initial TMDL, which would have imposed a 1 ng/l mercury limit for discharges to the middle/lower Savannah River, was revised to 2.8 ng/l in the final TMDL released in February 2001. The TMDL was intended to protect people from the consumption of contaminated fish, which is the major route of mercury exposure to humans. The most bioaccumulative form of mercury is methylmercury, which is produced in aquatic environments by the action of microorganisms on inorganic mercury. Because of the environmental and economic significance of the mercury discharge limits that would have been imposed by the TMDL, the Savannah River Site (SRS) initiated several studies concerning: (1) mercury in SRS discharges, SRS streams and the Savannah River, (2) mercury bioaccumulation factors for Savannah River fish, (3) the use of clams to monitor the influence of mercury from tributary streams on biota in the Savannah River, and (4) mercury in rainwater falling on the SRS. The results of these studies are presented in detail in this report. The first study documented the occurrence, distribution and variation of total and methylmercury at SRS industrial outfalls, principal SRS streams and the Savannah River where it forms the border with the SRS. All of the analyses were performed using the EPA Method 1630/31 ultra low-level and contaminant-free techniques for measuring total and methylmercury. Total mercury at National Pollutant Discharge Elimination System (NPDES) outfalls ranged from 0.31-604 ng/l with a mean of 8.71 ng/l. Mercury-contaminated groundwater was the source for outfalls with significantly elevated mercury concentrations. Total mercury in SRS streams ranged from 0.95-15.7 ng/l. Mean total mercury levels in the streams varied from 2.39 ng/l in Pen Branch to 5.26 ng/l in Tims Branch

    'Work compatibility' (WC) is a multi-dimensional diagnostic tool for measuring human performance that affects safety performance of work force. There are a dearth of literature on the use of WC in industrial applications. In this study, the status of WC and its components across employees' demographics such as age, experience, designation and location of work were examined in a steel plant in India. Data on 119 employees collected using Demand-Energizer Instrument was analysed. The results revealed that supervisors perceive higher energizers, higher demands and low WC as compared to workers. Older and high experience employees perceive higher energizers, lower demands and high WC as compared to younger and less experienced employees. All employee groups perceive higher demand for physical environment and physical task content. The problematic work groups identified are less experienced employees and workers in 'allied sections'. The outcomes of the study help the management in three ways to improve human performance at work places: (i) it provides useful information about the work factors to be considered for intervention design, (ii) it identifies the work groups to be targeted while preparing intervention strategies and (iii) it can be used as a leading indicator of human performance.

    Abstract Based on a thorough review of the available literature in the delayed-onset muscle soreness (DOMS) model, we identified multiple study design characteristics that are considered to be normative in acute pain research but have not been followed in a majority of published DOMS experiments. We designed an analgesic investigation using the DOMS model that both complied with current scientifically accepted standards for the conduct of analgesic studies and demonstrated reasonable assay sensitivity. This randomized, double-blind, placebo-controlled within-subject study compared the efficacy of topical diclofenac sodium 1% with a matching placebo in reducing pain associated with DOMS. After exercise, subjects reporting DOMS received topical diclofenac sodium gel 1% (DSG 1%) applied to one leg and placebo to the other every 6 hours for 48 hours. Pain intensity was assessed at rest, upon standing, and when walking in the 48 hours after initial drug application (T0). The primary end point was the reduction in pain intensity (SPID 24) on walking. Subjects receiving DSG 1% had less pain while walking compared with those receiving placebo at 24 hours (SPID 24 = 34.9 [22.9] and 23.6 [19.4], respectively; P = 0.032). This investigation used experimental techniques that have been vetted in the field of exercise physiology and superimposed techniques that are considered to be best practice in the field of analgesic research. Over time and with the help of colleagues in both fields of study, similar investigations will validate design features that impact the assay sensitivity of analgesic end points in DOMS models. In addition, the study confirmed the analgesic efficacy of topical DSG 1% over placebo in subjects experiencing DOMS. PMID:25633158

    Our study falls in line with the numerous studies providing a critique of the use of western diagnostic instruments for assessing trauma in a cross-cultural context. Our purpose has been to give evidence for the Tibetan torture survivors' degree of traumatisation and for their use of spirituality to overcome their difficult situation. In addition we wanted to question the use of our western methods in an Asian context. 102 tortured refugees attended a formalised needs assessment including neuropsychological and psychological measures of Post Traumatic Stress Disorder (PTSD) and the Hopkins Symptom Checklist 25 (HSCL-25). Even though significant correlations between the amount of the measures of organized violence and neuropsychological and psychological distress were found in our data, the division of the material into different subgroups according to e.g. religious and non-religious groups did not have an influence on the level of distress. After the assessment study, eight Tibetan lamas were interviewed about their views on our methods and results. They questioned the validity of our western rating scales and explained that our results might be influenced by the Tibetan culture, which among other things can be characterized as having a view and articulation of suffering much more complex than the units of our study's rating scales.

    Within programmatic assessment, the ambition is to simultaneously optimise the feedback and the decision-making function of assessment. In this approach, individual assessments are intended to be low stakes. In practice, however, learners often perceive assessments designed to be low stakes as high stakes. In this study, we explored how learners perceive assessment stakes within programmatic assessment and which factors influence these perceptions. Twenty-six learners were interviewed from three different countries and five different programmes, ranging from undergraduate to postgraduate medical education. The interviews explored learners' experience with and perception of assessment stakes. An open and qualitative approach to data gathering and analyses inspired by the constructivist grounded theory approach was used to analyse the data and reveal underlying mechanisms influencing learners' perceptions. Learners' sense of control emerged from the analysis as key for understanding learners' perception of assessment stakes. Several design factors of the assessment programme provided or hindered learners' opportunities to exercise control over the assessment experience, mainly the opportunities to influence assessment outcomes, to collect evidence and to improve. Teacher-learner relationships that were characterised by learners' autonomy and in which learners feel safe were important for learners' believed ability to exercise control and to use assessment to support their learning. Knowledge of the factors that influence the perception of assessment stakes can help design effective assessment programmes in which assessment supports learning. Learners' opportunities for agency, a supportive programme structure and the role of the teacher are particularly powerful mechanisms to stimulate the learning value of programmatic assessment. © 2018 The Authors.

  20. Assessing ScanSAR Interferometry for Deformation Studies

    Science.gov (United States)

    Buckley, S. M.; Gudipati, K.

    2007-12-01

    There is a trend in civil satellite SAR mission design to implement an imaging strategy that incorporates both stripmap mode and ScanSAR imaging. This represents a compromise between high resolution data collection and a desire for greater spatial coverage and more frequent revisit times. However, mixed mode imaging can greatly reduce the number of stripmap images available for measuring subtle ground deformation. Although ScanSAR-ScanSAR and ScanSAR-stripmap repeat-pass interferometry have been demonstrated, these approaches are infrequently used for single interferogram formation and nonexistent for InSAR time series analysis. For future mission design, e.g., a dedicated US InSAR mission, the effect of various ScanSAR system parameter choices on InSAR time series analysis also remains unexplored. Our objective is to determine the utility of ScanSAR differential interferometry. We will demonstrate the use of ScanSAR interferograms for several previous deformation studies: localized and broad-scale urban land subsidence, tunneling, volcanic surface movements and several examples associated with the seismic cycle. We also investigate the effect of various ScanSAR burst synchronization levels on our ability to detect and make quality measurements of deformation. To avoid the issues associated with Envisat ScanSAR burst alignment and to exploit a decade of InSAR measurements, we simulate ScanSAR data by bursting (throwing away range lines of) ERS-1/2 data. All the burst mode datasets are processed using a Modified SPECAN algorithm. To investigate the effects of burst misalignment, a number of cases with varying degrees of burst overlap are considered. In particular, we look at phase decorrelation as a function of percentage of burst overlap. Coherence clearly reduces as the percentage of overlap decreases and we find a useful threshold of 40-70% burst overlap depending on the study site. In order to get a more generalized understanding for different surface conditions

    Full Text Available During the recent financial crisis of insurance domain, there were imposed new aspects that have to be taken into account concerning the risks management and surveillance activity. The insurance societies could develop internal models in order to determine the minimum capital requirement imposed by the new regulations that are to be adopted on 1 January 2016. In this respect, the purpose of this research paper is to offer a real presentation and comparing with the main solvency regulation systems used worldwide, the accent being on their common characteristics and current tendencies. Thereby, we would like to offer a better understanding of the similarities and differences between the existent solvency regimes in order to develop the best regime of solvency for Romania within the Solvency II project. The study will show that there are clear differences between the existent Solvency I regime and the new approaches based on risk and will also point out the fact that even the key principles supporting the new solvency regimes are convergent, there are a lot of approaches for the application of these principles. In this context, the question we would try to find the answer is "how could the global solvency models be useful for the financial surveillance authority of Romania for the implementation of general model and for the development of internal solvency models according to the requirements of Solvency II" and "which would be the requirements for the implementation of this type of approach?". This thing makes the analysis of solvency models an interesting exercise.

    Waste effluents collected from different processing units of a pulp-mill were analyzed for various physiochemical parameters i.e. appearance, pH, conductance, total dissolved and suspended solids (TDS and TSS), chemical oxygen demand (COD) and 5- days biochemical oxygen demand (BOD/sub 5/). Various ions with reference to pulping process were investigated in these effluents which include Cr, SO/sub 4/sup 2-/, SO/sub 3/sup 2-/, CO/sub 3/sup 2-/HCO/sub 3/sup 1-/, Na/sup +/, K/sup +/, Mg/sup +2/ and Ca/sup +2/. Heavy metals like Hg, Pb, Fe, Cr, Cu and Zn was also determined by atomic absorption spectrometry. The results were compared with National Environmental Quality Standards for industrial effluents. Most of the parameters were found outside the permissible limits except the temperature, pH and few cations. Effluents from NSSC process exhibited highest values of TDS, TSS, COD and BODs (these are 103174, 31866, 23340, 6864 mg/l respectively). Chief polluting characteristics of these effluents were found to be the dissolved chemicals and suspended organic matter, which are responsible for very high COD and BODs values. This study was: an effort to monitor the concentration of various pollutants in the waste effluents of pulp and paper industry with special emphasis on NSSC effluents and their contribution in environmental pollution. The hazardous effects of these effluents and different treatment methodologies have also been discussed. (author)

    Continuing education for certified athletic trainers is both required and essential. The purpose of this study was to determine the need, including solutions and priorities, for continuing education for athletic trainers in various employment settings. Focus group sessions were conducted during the Spring 1992 District 4 meeting of the National Athletic Trainers Association. Representatives for each of the following employment settings were selected from the preregistration list and invited to participate: high school (7 participated), college/university (8), corporate/industrial (6), professional (3), and clinical (8). Data were compiled from written lists and audio cassette recordings of group discussions. Focus group participants across all employment settings felt that their primary continuing education needs were not being addressed at district meetings. Less traditional topics (eg, ergonomics, budgeting, public relations, and functional capacity evaluations) were identified as the more essential education needs. Focus group opinions varied somewhat regarding specific topics and methods of presentation. Recommendations included a more thematic approach to topics and presentations and ample opportunities for work or discussions in small groups. Results of the focus groups could impact the professional preparation of athletic trainers.

    Full Text Available Root-cause identification for quality related problems are key issues for manufacturing processes. It has been a very challenging engineering problem particularly in a multistage manufacturing, where maximum number of processes and activities are performed. However, it may also be implemented with ease in each and every individual set up and activities in any manufacturing process. Kaizen is aimed towards reduction in different types of losses i.e. Failure Loss/ Breakdown Loss, Minor stoppage, idling loss, Setup and adjustment loss etc. So as to improve quality and productivity.In this report, root-cause identification methodology has been adopted to eliminate the rejection of product manufactured by the enterprise and improving the life of product. Brainstorming and other Root Cause Assesmenttools have been used to find out the reasons of tube failure and vibration in tubular strander. Solutions of these problems have also given in this report. Kaizen activities have reduced the time consumed in daily activities of cleaning, lubricating, inspection etc. A detailed study has illustrated the effectiveness of the proposed methodology.

    Occupational radiation exposures of 13,475 civilian nuclear shipyard workers were investigated as part of a retrospective mortality study. Estimates of annual, cumulative and collective doses were tabulated for future dose-response analysis. Record sets were assembled and amended through range checks, examination of distributions and inspection. Methods were developed to adjust for administrative overestimates and dose from previous employment. Uncertainties from doses below the recording threshold were estimated. Low-dose protracted radiation exposures from submarine overhaul and repair predominated. Cumulative doses are best approximated by a hybrid log-normal distribution with arithmetic mean and median values of 20.59 and 3.24 mSv, respectively. The distribution is highly skewed with more than half the workers having cumulative doses 95% having doses <100 mSv. The maximum cumulative dose is estimated at 649.39 mSv from 15 person-years of exposure. The collective dose was 277.42 person-Sv with 96.8% attributed to employment at Portsmouth Naval Shipyard.

  9. Assessing atmospheric temperature data sets for climate studies

    Directory of Open Access Journals (Sweden)

    Magnus Cederlöf

    2016-07-01

    Full Text Available Observed near-surface temperature trends during the period 1979–2014 show large differences between land and ocean, with positive values over land (0.25–0.27 °C/decade that are significantly larger than over the ocean (0.06–0.12 °C/decade. Temperature trends in the mid-troposphere of 0.08-0.11 °C/decade, on the other hand, are similar for both land and ocean and agree closely with the ocean surface temperature trend. The lapse rate is consequently systematically larger over land than over the ocean and also shows a positive trend in most land areas. This is puzzling as a response to external warming, such as from increasing greenhouse gases, is broadly the same throughout the troposphere. The reduced tropospheric warming trend over land suggests a weaker vertical temperature coupling indicating that some of the processes in the planetary boundary layer such as inversions have a limited influence on the temperature of the free atmosphere. Alternatively, the temperature of the free atmosphere is influenced by advection of colder tropospheric air from the oceans. It is therefore suggested to use either the more robust tropospheric temperature or ocean surface temperature in studies of climate sensitivity. We also conclude that the European Centre for Medium-Range Weather Forecasts Reanalysis Interim can be used to obtain consistent temperature trends through the depth of the atmosphere, as they are consistent both with near-surface temperature trends and atmospheric temperature trends obtained from microwave sounding sensors.

    The chest pain can be use for stratifying the risk of the patients after coronary angioplasty. Nevertheless this strategy has shown to have a low accuracy in the detection of restenosis and myocardial ischemia. Aims: To establish the usefulness of the SPECT studies in the risk stratification after the coronary angioplasty. Evaluate the incidence of silent ischemia or symptomatic, and its impact on the prognosis. Method: There were included 107 patients (p) submitted to a gated SPECT between the year of the coronary angioplasty. The analysis of the images was performed according to different scores (SSS, SRS, SDS). These data was correlated with the symptoms of the patients. We define group 1 (G1) as the asymptomatic without ischemia (n 59p), group 2 (G2) as silent ischemia (n = 28p) and group 3 (G3) as symptomatic with ischemia (n = 20p). A clinical follow-up was done in search of events (target vessel revascularization, unstable angina, AMI and death). Results: Significant differences were not observed in the clinical variables between the different groups. The SSS was lower in the G1 compare with G2 and G3 (p 0.0001) and was similar between the last two, p = NS (SSS: G1: 2.2 ± 4.9; G2: 7.6 ± 5.9; G3: 9.5 ± 6.8). The SDS was greater in G3 vs. G1 and G2, p = 0.0001, and greater in G2 vs. G1, p = 0.0001 (SDS: G1: 0; G2: 4.8 ± 3.5; G3: 7.2 ± 6.5). No differences where observed in the SRS between the three groups. In the follow-up the total percentage of events was lesser when compare the G1 with the G2 and G3 (G1: 3.3%; G2 and G3: 18.7%; p 0.02). The percentage of annual events of the G3 symptomatic with ischemia (11.03%) and G2 silent ischemia (4.04%) did not present differences (p 0.7). When the events of the G2 (4.04%) were compared with the G1 (1.24%) we observed a trend to major frequency of events in the G2 (p = 0.6). Conclusions: The presence of myocardial ischemia after coronary angioplasty is a determinant of the prognosis. Nevertheless, the extension

    2015-09-01

    Pain assessment in people living with dementia is a challenge due to the complexity of pain and dementia and the difficulties in self-reporting. In home healthcare, nurses are frequently involved in pain assessment situations and there is a need to explore how home healthcare teams' manage pain assessment in this setting. The study aimed to explore home healthcare teams' experiences of pain assessment among care recipients with dementia. An exploratory qualitative design was used. Open-ended individual interviews were conducted with thirteen registered nurses and ten nursing assistants, working in three different home healthcare teams in one municipality in western Sweden. Philosophical hermeneutics was utilised to interpret the home healthcare teams' experiences. Four interpretations emerged: the need for trusting collaboration, the use of multiple assessment strategies, maintenance of staff continuity in care and assessment situations, and the need for extended time to assess pain. The home healthcare teams recognise pain assessment in people with dementia as involving a complex interaction of sensory, cognitive, emotional and behavioural components in which efforts to acquire understanding of behavioural changes mainly guides their assessments. The solid team coherence between registered nurses and nursing assistants aided the assessment procedure. To assess pain, the teams used multiple methods that complemented one another. However, no systematic routines or appropriate evidence-based pain tools were used. The team members'concern for care recipients when assessing pain is evident and needs to be acknowledged by the organisation which is responsible for the quality of care. Future studies should focus on further exploration of nurses' experiences with pain and dementia in home healthcare settings and address what nurses identify and how they deal with their findings. It is imperative to investigate how organisations and nurses can ensure best practices and how

    2003-12-01

    A framework for Strategic Environmental Assessment (SEA) is tested in a case study on a proposed waste incineration tax. Also included is testing of developed methods for valuation and site-dependent life cycle impact assessment. The results indicate that although a suggested waste incineration tax of 400 SEK/ton is likely to lead to environmental improvements, these are small compared to the potential improvements as shown in more visionary scenarios. In order to go in this direction a waste incineration tax based on the content of fossil carbon in the waste would be useful. The framework for SEA includes several different pathways. These have different advantages and disadvantages and provide different types of information. It is therefore suggested that they largely complement each other and that the choice of methods should be done in relation to the function of the SEA and the questions asked.

    An approach for evaluating and integrating genomic data in chemical risk assessment was developed based on the lessons learned from performing a case study for the chemical dibutyl phthalate. A case study prototype approach was first developed in accordance with EPA guidance and recommendations of the scientific community. Dibutyl phthalate (DBP) was selected for the case study exercise. The scoping phase of the dibutyl phthalate case study was conducted by considering the available DBP genomic data, taken together with the entire data set, for whether they could inform various risk assessment aspects, such as toxicodynamics, toxicokinetics, and dose–response. A description of weighing the available dibutyl phthalate data set for utility in risk assessment provides an example for considering genomic data for future chemical assessments. As a result of conducting the scoping process, two questions—Do the DBP toxicogenomic data inform 1) the mechanisms or modes of action?, and 2) the interspecies differences in toxicodynamics?—were selected to focus the case study exercise. Principles of the general approach include considering the genomics data in conjunction with all other data to determine their ability to inform the various qualitative and/or quantitative aspects of risk assessment, and evaluating the relationship between the available genomic and toxicity outcome data with respect to study comparability and phenotypic anchoring. Based on experience from the DBP case study, recommendations and a general approach for integrating genomic data in chemical assessment were developed to advance the broader effort to utilize 21st century data in risk assessment. - Highlights: • Performed DBP case study for integrating genomic data in risk assessment • Present approach for considering genomic data in chemical risk assessment • Present recommendations for use of genomic data in chemical risk assessment.

    Full Text Available Spray drying has been successfully employed for the encapsulation of herbal bioactive compounds resulting in stable phytopharmaceutical preparations. Bidens pilosa L. is a South American medicinal plant with proved antimalaric, hepatoprotector and antioxidant activities, generally linked to their secondary metabolites, flavonoids and polyacetylenes. In this work the physicochemical stability of an optimized spray dried composition from a B. pilosa extract was evaluated at three different stress storage conditions in open containers and in sealed sachets. High performance liquid chromatography was employed to monitor the concentration of three marker compounds over 12 months. Color variation of the stored samples was evaluated by using a color spectrophotometer. It was observed that the concentration of the monitored compounds of the plant decreases more drastically in samples stored in open containers. The two flavonoids monitored, rutin and hyperoside, showed lower degradation than the polyacetylene. The concentration of the markers did not change significantly at the lowest temperature. With regard to color, darker hues were observed at higher temperatures and storage times. This study showed that the storage conditions cause significant impact on stability of standardized spray dried B. pilosa extract.

    The purpose of this case study is to illustrate, using an actual example, the organizing and carrying out of an independent peer review of a draft full-scope (level 3) probabilistic safety assessment. The specific findings of the peer review are of less importance than the approach taken, the interaction between sponsor and study team, and the technical and administrative issues that can arise during a peer review. This case study will examine the following issues: how the scope of the peer review was established, based on how it was to be used by the review sponsoring body; how the level of effort was determined, and what this determination meant for the technical quality of the review; how the team of peer reviewers was selected; how the review itself was carried out; what findings were made; what was done with these findings by both the review sponsoring body and the PSA analysis team. 9 refs, 2 figs, 1 tab

    2017-12-01

    This 28-day pilot study assessed the feasibility of cell phone ecological momentary assessment in 40 smokers who received emergency department evaluations for acute coronary syndrome. Ecological momentary assessments used familiar touch tone response technology during a cell phone call to capture ratings of illness perceptions, emotion, behavioral intentions, and smoking. Ecological momentary assessments were conducted 1-8 times/day and took 1-2 minutes to complete. The mean ecological momentary assessment call compliance for all 40 subjects was 56.3 percent (standard deviation = 29.4), and during an ecological momentary assessment, 72.5 percent of participants reported a first lapse. We found that first-week call compliance was significantly correlated with subsequent compliance ( r = 0.55, p < 0.001).

  14. Revision Vodcast Influence on Assessment Scores and Study Processes in Secondary Physics

    Science.gov (United States)

    Marencik, Joseph J.

    A quasi-experimental switching replications design with matched participants was employed to determine the influence of revision vodcasts, or video podcasts, on students' assessment scores and study processes in secondary physics. This study satisfied a need for quantitative results in the area of vodcast influence on students' learning processes. Thirty-eight physics students in an urban Ohio public high school participated in the study. The students in one Physics class were paired with students in another Physics class through the matching characteristics of current student cumulative test score mean and baseline study process as measured by the Study Process Questionnaire (SPQ). Students in both classes were given identical pedagogic treatment and access to traditional revision tools except for the supplemental revision vodcasts given to the experimental group. After students in the experimental group viewed the revision vodcast for a particular topic, the assessment scores of the students in the experimental group were compared to the assessment scores of the control group through the direct-difference, D, test to determine any difference between the assessment score means of each group. The SPQ was given at the beginning of the experiment and after each physics assessment. The direct-difference method was again used to determine any difference between the SPQ deep approach scores of each group. The SPQ was also used to determine any correlative effects between study process and revision vodcast use on students' assessment scores through descriptive statistics and an analysis of variance (ANOVA) test. Analysis indicated that revision vodcast use significantly increased students' assessment scores (p.05). There were no significant correlative effects of revision vodcast use and study processes on students' assessment scores (p>.05). This study offers educators the empirical support to devote the necessary effort, time, and resources into developing successful

    Koschwanez, Heidi E; Broadbent, Elizabeth

    2011-02-01

    To provide a critical review of methods used to assess human wound healing in psychological research and related disciplines, in order to guide future research into psychological influences on wound healing. Acute wound models (skin blister, tape stripping, skin biopsy, oral palate biopsy, expanded polytetrafluoroethylene tubing), surgical wound healing assessment methods (wound drains, wound scoring), and chronic wound assessment techniques (surface area, volumetric measurements, wound composition, and assessment tools/scoring systems) are summarized, including merits, limitations, and recommendations. Several dermal and mucosal tissue acute wound models have been established to assess the effects of psychological stress on the inflammatory, proliferative, and repair phases of wound healing in humans, including material-based models developed to evaluate factors influencing post-surgical recovery. There is a paucity of research published on psychological factors influencing chronic wound healing. There are many assessment techniques available to study the progression of chronic wound healing but many difficulties inherent to long-term clinical studies. Researchers need to consider several design-related issues when conducting studies into the effects of psychological stress on wound healing, including the study aims, type of wound, tissue type, setting, sample characteristics and accessibility, costs, timeframe, and facilities available. Researchers should consider combining multiple wound assessment methods to increase the reliability and validity of results and to further understand mechanisms that link stress and wound healing. ©2010 The British Psychological Society.

    2014-01-01

    Communication between clinicians related to attention-deficit/hyperactivity disorder (ADHD) assessment is challenging because it involves a number of individuals. While the communication process might be more efficient if these individuals worked together, research on ADHD-specific collaborative care models is scarce. The purpose of this qualitative study was to investigate the parties with whom prescribers communicate and how they collaborate. Providers were interviewed, and the data were analyzed using a phenomenological case study approach. The results suggested that there were communication breakdowns between providers and teachers that hindered the assessment process. Communication related to ADHD assessment may be more complex than theoretical models may conceptualize.

  18. Towards a structured approach to Strategic Environmental Assessment: A case study of Canadian energy policy alternatives

    Science.gov (United States)

    Noble, Bram F.

    Considerable attention has been given to the role of Strategic Environmental Assessment (SEA) in policy, plan and program (PPP) assessment; however, there is still very little consensus on appropriate methodologies for SEA. Despite calls for SEA to develop more independently of project-level assessment, existing SEA methodologies still tend to be based on project-level EIA principles, rather than also on a trickling down of objectives of broader environmental policy. This thesis argues that if SEA is to advance in application and effectiveness then a different, but structured methodological framework is required. While SEA can perhaps utilize many of the existing methods and techniques from project-level assessment, the types of questions being addressed in strategic assessment are inherently different from those in project-level assessment. Accordingly, a different methodological assessment framework is required for SEA. The emphasis of strategic assessment is on the development of an appropriate strategy for action, addressing alternative courses of action, rather than the assessment of the potential impacts of a pre-determined option. In order to accomplish this, SEA methodology must be more broad brush than project-level assessment in order to allow the assessment of both the more general policy issues and the more technical plan and program issues. Similar to project-level assessment, however, a structured framework is desired in order to facilitate a more systematic and replicable assessment process. This thesis develops a structured, generic seven-phase assessment framework to guide SEA application. The framework is demonstrated through a case study SEA of potential Canadian energy policy alternatives. Through the use of a modified policy-type Delphi and multi-criteria analytical methods, alternative options for Canadian energy policy are evaluated and the 'best practicable environmental option' is determined. While the geographic scale of the case study and

    Although systematic reviews of epidemiologic studies have been conducted for condom use and the risk of several sexually transmitted diseases, there have been no such reviews for condom use and syphilis. A systematic literature review of epidemiologic studies published from 1972 to 2008 was conducted to evaluate study methods and measures of association reported for condom use and risk of syphilis. All 12 included studies had significant methodologic limitations. Nine (75%) studies were cross-sectional. Although 11 (92%) studies assessed consistent condom use, no studies assessed correct use or condom use problems, nor did any document exposure to a partner infected with syphilis. Ten studies had insufficient information to distinguish prevalent from incident infections. Two studies that assessed both incident infection and consistent condom use suggested a reduced risk of syphilis with consistent condom use; 1 study was statistically significant. Significant methodologic limitations exist for all reviewed studies of syphilis and condom use. Among the 2 most rigorously designed studies, both suggested a reduced risk of syphilis with consistent condom use. Additional studies incorporating rigorous methods are needed to further assess the effect of condom use on risk of syphilis.

    To combine empirical evidence and expert opinion in a formal consensus method in order to develop a quality-assessment tool for experimental bruxism studies in systematic reviews. Tool development comprised five steps: (1) preliminary decisions, (2) item generation, (3) face-validity assessment, (4) reliability and discriminitive validity assessment, and (5) instrument refinement. The kappa value and phi-coefficient were calculated to assess inter-observer reliability and discriminative ability, respectively. Following preliminary decisions and a literature review, a list of 52 items to be considered for inclusion in the tool was compiled. Eleven experts were invited to join a Delphi panel and 10 accepted. Four Delphi rounds reduced the preliminary tool-Quality-Assessment Tool for Experimental Bruxism Studies (Qu-ATEBS)- to 8 items: study aim, study sample, control condition or group, study design, experimental bruxism task, statistics, interpretation of results, and conflict of interest statement. Consensus among the Delphi panelists yielded good face validity. Inter-observer reliability was acceptable (k = 0.77). Discriminative validity was excellent (phi coefficient 1.0; P reviews of experimental bruxism studies, exhibits face validity, excellent discriminative validity, and acceptable inter-observer reliability. Development of quality assessment tools for many other topics in the orofacial pain literature is needed and may follow the described procedure.

    2016-01-01

    Objective: While a growing body of research indicates that implicit cognitive processes play an important role in a range of health behaviors, the assessment of these impulsive, associative mental processes among patients living with HIV has received little attention. This preliminary study explored how multidimensional scaling (MDS) could be used to assess implicit cognitive processes among patients lost to follow-up for HIV care and develop interventions to improve their engagement. Method: The sample consisted of 33 patients who were identified as lost to follow up for HIV care at two urban hospitals. Participants were randomly assigned to either the MDS assessment program or control group. All participants underwent measures designed to gauge behavioral change intentions and treatment motivation. Assessment group participants were interviewed to determine their reactions to the assessment program. Results: The MDS assessment program identified cognitive processes and their relationship to treatment-related behaviors among assessment group participants. Assessment group participants reported significantly greater behavior change intentions than those in the control group (p =.02; Cohen’s d = 0.84). Conclusion: MDS shows promise as a tool to identify implicit cognitive processes related to treatment-related behaviors. Assessments based on MDS could serve as the basis for patient-centered clinical interventions designed to improve treatment adherence and HIV care engagement in general. PMID:27347274

    Assessment of one's academic capabilities is essential to being an effective, self-directed, life-long learner. The primary objective of this study was to analyze self-assessment accuracy of medical students attending the College of Medicine and Health Sciences, United Arab Emirates University, by examining their ability to assess their own performance on an MCQ examination. 1 st and 2 nd year medical students (n = 235) self-assessed pre and post-examination performance were compared with objectively measured scores (actual examination performance). Associations between accuracy of score prediction (pre and post assessment), and students' gender, year of education, perceived preparation, confidence and anxiety were also determined. Expected mark correlated significantly with objectively assessed marks (r = 0.407; P self-assessment accuracy. Findings reinforce existing evidence indicating that medical students are poor self-assessors. There are potentially multiple explanations for misjudgment of this multidimensional construct that require further investigation and change in learning cultures. The study offers clear targets for change aimed at optimizing self-assessment capabilities.

    This study was undertaken to determine if the U.S. Geological Survey’s process for conducting mineral resource assessments on Earth can be applied to asteroids. Successful completion of the assessment, using water and iron resources to test the workflow, has resulted in identification of the minimal adjustments required to conduct full resource assessments beyond Earth. We also identify the types of future studies that would greatly reduce uncertainties in an actual future assessment. Whereas this is a feasibility study and does not include a complete and robust analysis of uncertainty, it is clear that the water and metal resources in near-Earth asteroids are sufficient to support humanity should it become a fully space-faring species.

    Retaining severely impaired individuals poses a major challenge in longitudinal studies of determinants of dementia or memory decline. In the Health and Retirement Study (HRS), participants complete direct memory assessments biennially until they are too impaired to complete the interview. Thereafter, proxy informants, typically spouses, assess the subject's memory and cognitive function using standardized instruments. Because there is no common scale for direct memory assessments and proxy assessments, proxy reports are often excluded from longitudinal analyses. The Aging, Demographics, and Memory Study (ADAMS) implemented full neuropsychological examinations on a subsample (n=856) of HRS participants, including respondents with direct or proxy cognitive assessments in the prior HRS core interview. Using data from the ADAMS, we developed an approach to estimating a dementia probability and a composite memory score on the basis of either proxy or direct assessments in HRS core interviews. The prediction model achieved a c-statistic of 94.3% for DSM diagnosed dementia in the ADAMS sample. We applied these scoring rules to HRS core sample respondents born 1923 or earlier (n=5483) for biennial assessments from 1995 to 2008. Compared with estimates excluding proxy respondents in the full cohort, incorporating information from proxy respondents increased estimated prevalence of dementia by 12 percentage points in 2008 (average age=89) and suggested accelerated rates of memory decline over time.

    Lindström, Veronica; Heikkilä, Kristiina; Bohm, Katarina; Castrèn, Maaret; Falk, Ann-Charlotte

    2014-11-11

    Previous studies have described the difficulties and the complexity of assessing an emergency call, and assessment protocols intended to support the emergency medical dispatcher's (EMD) assessment have been developed and evaluated in recent years. At present, the EMD identifies about 50-70 % of patients suffering from cardiac arrest, acute myocardial infarction or stroke. The previous research has primarily been focused on specific conditions, and it is still unclear whether there are any overall factors that may influence the assessment of the call to the emergency medical communication centre (EMCC). The aim of the study was to identify overall factors influencing the registered nurses' (RNs) assessment of calls to the EMCC. A qualitative study design was used; a purposeful selection of calls to the EMCC was analysed by content analysis. One hundred calls to the EMCC were analysed. Barriers and opportunities related to the RN or the caller were identified as the main factors influencing the RN's assessment of calls to the EMCC. The opportunities appeared in the callers' symptom description and the communication strategies used by the RN. The barriers appeared in callers' descriptions of unclear symptoms, paradoxes and the RN's lack of communication strategies during the call. Barriers in assessing the call to the EMCC were associated with contradictory information, the absence of a primary problem, or the structure of the call. Opportunities were associated with a clear symptom description that was also repeated, and the RN's use of different communication strategies such as closed loop communication.

    2017-06-06

    Alcohol consumption creates a significant public health burden, and young people who drink alcohol place themselves at risk of harm. Expert guidance and reviews have highlighted the pressing need for reliable and valid, age-appropriate alcohol screening and assessment measures for young people. The proposed systematic review will evaluate existing alcohol screening and assessment measures for young people aged 24 and under. Six electronic databases will be searched for published and grey literature. In addition, reverse and forward citation searching and consultation with experts will be performed. Three sets of search terms will be combined, including alcohol use/problems, young people and validation studies. The titles and abstracts of reports from the searches will be screened, and potentially relevant full-text reports will be retrieved and independently assessed for inclusion by two reviewers based on prespecified criteria. Discrete validation studies within included reports will then be assessed for eligibility. There will be an a priori basic quality threshold for predictive validity, internal and test-retest for studies to warrant full data extraction. Studies above the quality threshold will be assessed for quality using the modified consensus-based standards for the selection of health measurement instruments checklist and a quality assessment tool for diagnostic accuracy studies. This review will highlight the best performing measures both for screening and assessment based on their psychometric properties and the quality of the validation studies supporting their use. Providing clear guidance on which existing measures perform best to screen and assess alcohol use and problems in young people will inform policy, practice and decision-making, and clarify the need for further research.

    There are many different ways of providing university students with feedback on their assessment performance, ranging from written checklists and handwritten commentaries to individual verbal feedback. Regardless of whether the feedback is summative or formative in nature, it is widely recognized that providing consistent, meaningful written feedback to students on assessment performance is not a simple task, particularly where a module is delivered by a team of staff. Typical student complaints about such feedback include: inconsistency of comment between lecturers; illegible handwriting; difficulty in relating feedback to assessment criteria; and vague remarks. For staff themselves, there is the problem that written comments, to be of any benefit to students, are immensely time-consuming. This paper illustrates, through a case study, the enormous benefits of Automated Assessment Feedback for staff and students. A clear strategy on how to develop an automated assessment feedback system, using the simplest of technologies, is provided.

    ABSTRACT Assessing methodological quality is a necessary activity for any systematic review, including those evaluating the evidence for studies of medical test performance. Judging the overall quality of an individual study involves examining the size of the study, the direction and degree of findings, the relevance of the study, and the risk of bias in the form of systematic error, internal validity, and other study limitations. In this chapter of the Methods Guide for Medical Test Reviews,...

  13. Written reflection and drawing as assessment: A case study of a Navajo elementary science classroom

    Becker, Madeline

    The purpose of the study was to assess if science learning could be determined by using written reflection and drawings in a science classroom of 5 th-grade Navajo students. The significance of this study was the understanding of the culture, assessments and learning of Navajo students. I studied a classroom on the Navajo reservation wherein 26 members of the class took part in science instruction complemented by using writing and drawing which were used as their assessments. The perceptions of the 8 students who were interviewed represent the case. In the study I profiled the 8 participants. Their culture, language, and views on assessment and learning were documented by their words. Their responses described their learning experiences. Assessments were seen as frustrating and limiting expression of what was known and damaging when not contributed to learning. Students explained that drawing enabled them to remember along with provoking vocabulary development. Student cultural knowledge was documented as valuable background experience contributing to learning within the classroom. Students viewed science as needing to be useful in their culture. Finally, they were also very candid that their teachers must first get to know them for meaningful learning to begin. Learning for students was reinforced through writing and drawing the lesson's activities. Further concept development was assisted utilizing metacognition and creative problem solving techniques of elaboration and fluency applied to the writing and drawings. Based on the findings of this study, recommendations were made for use of holistic means of assessing Navajo children in science where preferred learning styles along with cultural background need to be included in assessment protocols. Using new and better assessment techniques can directly impact how students document their learning as well as reveal how they acquire new knowledge.

    In between the description of the methodology and the discussion of assessment results, lies a crucial area, namely that of implementation. If assessment methods cannot be implemented, there will be no assessment report, and no recommendations for intervention or policy development. Implementation is a critical, yet neglected, area of drug policy delivery. This paper describes some of the problems associated with the implementation of rapid assessment studies commissioned by the United Nations International Drug Control Programme (UNDCP) over the last 5 years. Drawing on the author's experience of commissioning rapid assessments on the extent and nature of drug use in a variety of international settings and political contexts, the paper draws eight main lessons for rapid assessments commissioned within the context of international development programmes. These are: (1) the need to get high level political support; (2) the need to employ competent social scientists to run the assessment; (3) the need to define exactly the object of the assessment; (4) the necessity of spelling out the methodology and the time scale; (5) the careful establishment of the financial framework; (6) the importance of cultivating contacts; (7) the necessity of actually getting a report; and (8) the danger of accepting an unseen or unread consultant's report as the basis for programme implementation. The paper emphasises the critical importance of planning prior to implementation and flexibility during it.

    2012-06-01

    Shower assessments are complex and challenging tasks undertaken by many occupational therapists with little known about how they are conducted and how new graduates learn to carry these out. There are no published guidelines and limited opportunity for students to practise shower assessments during their training bringing into question how new graduates learn to do this assessment and judge their effectiveness. To investigate the experience of new graduate occupational therapists undertaking their first shower assessments in South Australia. Six graduate occupational therapists participated in a phenomenological study. Data were gathered through semi-structured interviews and analysed according to Giorgi's descriptive phenomenological method. New graduates found the shower assessment process cognitively and emotionally demanding. Without prior experience, new graduates lacked confidence to perform the practical aspects of conducting a shower assessment. The sense of responsibility for getting it right and ensuring client safety was at times overwhelming. Social norms around nudity, age and gender impacted on the graduate's interaction with clients in the shower environment. However, graduates with previous care attendant work were better able to manage the social and practical challenges inherent in shower assessments. The findings of this study suggest that additional experiential, 'hands on', learning is needed in university curriculum for new graduates to develop practical clinical skills, particularly as practice placements have become more diverse. Similarly there is a need for organisations to provide orientation activities and mentoring for new graduates as they transition from student to therapist. © 2012 The Authors Australian Occupational Therapy Journal © 2012 Occupational Therapy Australia.

    There is evidence that most South African oral hygiene lecturers lack appropriate qualifications in the field of education. Their teaching skills are based mainly on clinical and practical experience, and this may impact on their understanding of the educational foundations of teaching, learning and assessment. To explore oral hygiene lecturers' knowledge and use of pedagogy and assessment and its alignment. A qualitative descriptive study design was used and case studies of two oral hygiene lecturers, each with qualifications in Education, were analyzed according to three themes: curriculum, pedagogy and assessment. The results showed that both participants had a good understanding of formative assessment (FA) and summative assessment (SA). They made use of FA but in neither case was the application ideal. Both used a range of teaching and assessment strategies but felt accountable to external demands of meeting outcomes. They linked their understanding of pedagogy and assessment to assist in the development of their courses and reported that this alignment had improved the quality of their programmes. This alignment by oral hygiene lecturers can influence curricular and pedagogic strategies. The professional educational development of lecturers in oral hygiene could be influential in improving the profession within the country.

    Occ DEAS Assessing occupational exposure in retrospective community-based case-control studies is difficult as measured exposure data are very seldom available. The expert assessment method is considered the most accurate way to attribute exposure but it is a time consuming and expensive process and may be seen as subjective, non reproducible, and non transparent. In this paper, we describe these problems and outline our solutions as ope rationalized in a web-based software application (Occ DEAS). The novel aspects of Occ DEAS are combining all steps in the assessment into one software package; enmeshing the process of assessment into the development of questionnaires; selecting the exposure(s) of interest; specifying rules for exposure assignment; allowing manual or automatic assessments; ensuring that circumstances in which exposure is possible for an individual are highlighted for review; providing reports to ensure consistency of assessment. Development of this application has the potential to make high-quality occupational assessment more efficient and accessible for epidemiological studies

    In perinatal psychiatry, randomized controlled trials are often not feasible on ethical grounds. Many studies are observational in nature, while others employ large databases not designed primarily for research purposes. Quality assessment of the resulting research is complicated by a lack of standardized tools specifically for this purpose. The aim of this paper is to describe the Systematic Assessment of Quality in Observational Research (SAQOR), a quality assessment tool our team devised for a series of systematic reviews and meta-analyses of evidence-based literature regarding risks and benefits of antidepressant medication during pregnancy.

    Technological advances have allowed for the evolution of traditional dietary assessment methods. The aim of this review is to evaluate the accuracy of technology-based dietary assessment methods to determine carotenoid and/or fruit and vegetable intake when compared with carotenoid biomarkers. An online search strategy was undertaken to identify studies published in the English language up to July 2016. Inclusion criteria were adults ≥18 years, a measure of dietary intake that used information and communication technologies that specified fruit and/or vegetable intake or dietary carotenoid, a biomarker of carotenoid status and the association between the two. Sixteen articles from 13 studies were included with the majority cross-sectional in design (n = 9). Some studies used multiple dietary assessment methods with the most common: food records (n = 7), 24-h diet recalls (n = 5), food frequency questionnaires (n = 3) and diet quality assessed by dietary screener (n = 1). Two studies were directly web based, with four studies using technology that could be completed offline and data later transferred. Two studies utilised technology in the collection of dietary data, while the majority (n = 11) automated the collection in combination with nutrient analysis of the dietary data. Four studies provided correlation values between dietary carotenoids with biomarkers, ranging from r = 0.13 to 0.62 with the remaining studies comparing a measure of fruit and vegetable intake with biomarkers (r = 0.09 to 0.25). This review provides an overview of technology-based dietary assessment methods that have been used in validation studies with objectively measured carotenoids. Findings were positive with these dietary assessment measures showing mostly moderate associations with carotenoid biomarkers. PMID:28216582

    This presentation discussed the public relations and public opinion strategies used as part of a soils study conducted to assess the risk of mining activities in the Sudbury region to human health and the environment. The human health risk assessment (HHRA) study was conducted and administered by a multi-stakeholder technical committee attended by the public. The study was comprised of extensive soil collection and analysis; a review of historical soils data; and extensive human health and ecological risk assessments. Extensive sampling was also conducted on air, dust, and locally-produced foods. A public advisory committee was formed to disseminate scientific information to the community. Scientific data obtained in the study were reviewed by experts in various fields. Results of the study were also peer-reviewed by an independent expert review panel comprised of leading specialists in human health, toxicology, speciation, and risk assessment. The study showed that the identified risks were over-estimated in the interest of protecting human health. It was concluded that the HHRA's findings were generally accepted by the public. tabs., figs

    Kogan, Jennifer R; Conforti, Lisa N; Bernabeo, Elizabeth; Iobst, William; Holmboe, Eric

    2015-07-01

    Direct observation of clinical skills is a common approach in workplace-based assessment (WBA). Despite widespread use of the mini-clinical evaluation exercise (mini-CEX), faculty development efforts are typically required to improve assessment quality. Little consensus exists regarding the most effective training methods, and few studies explore faculty members' reactions to rater training. This study was conducted to qualitatively explore the experiences of faculty staff with two rater training approaches - performance dimension training (PDT) and a modified approach to frame of reference training (FoRT) - to elucidate how such faculty development can be optimally designed. In a qualitative study of a multifaceted intervention using complex intervention principles, 45 out-patient resident faculty preceptors from 26 US internal medicine residency programmes participated in a rater training faculty development programme. All participants were interviewed individually and in focus groups during and after the programme to elicit how the training influenced their approach to assessment. A constructivist grounded theory approach was used to analyse the data. Many participants perceived that rater training positively influenced their approach to direct observation and feedback, their ability to use entrustment as the standard for assessment, and their own clinical skills. However, barriers to implementation and change included: (i) a preference for holistic assessment over frameworks; (ii) challenges in defining competence; (iii) difficulty in changing one's approach to assessment, and (iv) concerns about institutional culture and buy-in. Rater training using PDT and a modified approach to FoRT can provide faculty staff with assessment skills that are congruent with principles of criterion-referenced assessment and entrustment, and foundational principles of competency-based education, while providing them with opportunities to reflect on their own clinical skills

  3. Worth it? Findings from a study of how academics assess students’ Web 2.0 activities

    Directory of Open Access Journals (Sweden)

    Kathleen Gray

    2012-02-01

    Full Text Available Educational commentators have offered many pedagogical rationales for using Web 2.0 to support learning in higher education, and academics are being encouraged to find ways for their students to use social web technologies. Questions arise as to the value of these activities compared to more conventional assignments, and whether implementing such changes to student assessment is worth the effort. We conducted a survey of academics’ assessment of students’ Web 2.0 activities in Australian universities and found that this form of assessment is being conducted by a small number of academics, in a range of fields of study, but mainly in Humanities and Social Sciences, with varying kinds of intended and actual learning outcomes. Blogging and wiki-writing predominate, low and medium-stakes assessment are most common, and different methods of marking and feedback are in use. Qualitative feedback from the survey and follow-up interviews gave further insights into benefits and challenges of Web 2.0 assessment in relation to pedagogy, policy and practice. It appears that academics’ conservative approaches to conducting assessment and their novice approaches to utilising social web technologies are factors which seriously limit realising the potential of Web 2.0 for medium or high-stakes assessment.

Patients' PPS scores were assessed in three sequential stages: prehospital, first PCT assessment, and outcome (discharge, transference to another unit or death). Functional performance was classified in categories as stable (PPS scores between 70% and 100%), transitional (PPS scores between 40% and 60%), and end of life (PPS scores between 10% and 30%). The mean PPS score during the three assessment stages (respectively, 60.5%, 38.9%, and 25.9%) was significantly different (p PPS scores than noncancer patients; however, both groups exhibited a functional decline along the hospital stay. In both groups there was a negative correlation between the time frame between the different assessment stages and PPS scores (respectively, Pearson -0.4 and -0.6; p PPS assessments are feasible and predicted functional decline in cancer and noncancer patients in this sample. Cancer patients exhibited higher initial functional scores but both cancer and noncancer patients declined in functionality along hospitalization. Earlier deaths occurred in the terminal PPS category than in the transitional PPS category.

    Full Text Available This paper aimed to identify the perception of undergraduate Management course students from the Federal University of Pernambuco (UFPE, Agreste Campus, about their professors’ assessment methods. A quantitative approach was employed through a questionnaire conducted on a research sample of 155 students. The data collected and analyzed revealed that the students in question pointed out didactic and bureaucratic functions as the reasons for undertaking assessments and recognized their importance only for students, as an indication of their performance. Most students stated that their feelings about the assessment processes vary according to their time of study and empathy for the discipline, and that the teaching-assessment ratio is generally positive. Assessment feedback was common practice for the sample, but there was a lack of diversity of assessment tools and those used clash with the ones they desired. In conclusion, according to the students’ perception, it is possible to develop multiple thoughts about the assessment process, driving improvements in educational practices and the formation and training of university professors.

    The objective of this study was to identify and assess opportunities for demonstration and large scale deployment of solar electric facilities in the southeast region and to define the technical, economic, and institutional factors that can contribute to an accelerated use of solar energy for electric power generation. Graphs and tables are presented indicating the solar resource potential, siting opportunities, energy generation and use, and socioeconomic factors of the region by state. Solar electric technologies considered include both central station and dispersed solar electric generating facilities. Central stations studied include solar thermal electric, wind, photovoltaic, ocean thermal gradient, and biomass; dispersed facilities include solar thermal total energy systems, wind, and photovoltaic. The value of solar electric facilities is determined in terms of the value of conventional facilities and the use of conventional fuels which the solar facilities can replace. Suitable cost and risk sharing mechanisms to accelerate the commercialization of solar electric technologies in the Southeast are identified. The major regulatory and legal factors which could impact on the commercialization of solar facilities are reviewed. The most important factors which affect market penetration are reviewed, ways to accelerate the implementation of these technologies are identified, and market entry paths are identified. Conclusions and recommendations are presented. (WHK)

    Full Text Available The purpose of this study was to establish normative data for the Barnett Balance Assessment (BBA for individuals ages 18-70+ years. The BBA is a newly developed assessment tool that may address limitations present in other assessments currently used to detect balance deficits. The BBA was administered to 141 participants who had no history of medical issues that could impact balance. A review of the normative data collected indicated little variation in total assessment scores in the age categories of 18-29, 30-39, and 40-49, due to the presence of a ceiling effect. Variations existed in scores among participants in the remaining age categories (50-59, 60-69, and 70+. These findings may imply that the BBA has its greatest discriminative power in assessing individuals with impaired balance, and/or that the BBA is not sensitive enough to detect differences in individuals with mild balance impairments. The researchers suggest future studies be conducted with the BBA to establish norms with populations with known orthopedic or neurological conditions that may impair balance. Results of these studies could then be compared with the baseline data gathered in this study to determine the BBA’s usefulness in detecting balance impairments with clinical populations.

    Full Text Available Concerns and uncertainties persist about potential environmental and health effects associated with exposure to emissions from widely adopted waste management facilities: despite a limited amount of evidence having been found for some exposure-effect associations, most of the available studies were characterized by limitations related to poor exposure assessment, which could introduce biases and weaknesses in the interpretation of results. This communication provides a brief overview of the exposure assessment methods used in studies on waste management and health effects: problems, key issues, priorities and challenges are briefly presented and discussed. The main conclusions refer to the need of newly developed and harmonized exposure assessment strategies and techniques, which represent an essential step in the study of waste-disposal facilities’ health impacts.

    Full Text Available Introduction: Malocclusion is a developmental condition signifying a mal-relationship between the arches. It is classified into several types and manifest variably from person to person. Aim: To evaluate the severity of the malocclusion and orthodontic treatment needs in 16–24-year-old Indian young adults. Materials and Methods: A cross-sectional study was conducted among 660 subjects (352 males; 308 females residing in rural areas of Dehradun, India. Clinical examinations were conducted using the dental esthetic index (DAI to evaluate the extent of orthodontic treatment needs among the population. Results: The mean DAI score of the sample was found to be 31.08 ± 7.98. No gender-wise differences were found. Statistically significant differences were observed between the age groups. Diastema between males and females was the only component where differences were found to be statistically significant. Conclusion: Around 45.15% of the total sample had a highly desirable and mandatory orthodontic treatment need. Gender did not influence treatment need whereas age group was found to influence it.

    Systematic suicide risk assessment is recommended for patients with schizophrenia; however, little is known about the implementation of suicide risk assessment in routine clinical practice. The study aimed to determine the use of systematic suicide risk assessment at discharge and predictors of suicide attempt among hospitalized patients with schizophrenia in Denmark. A one-year follow-up study was conducted of 9,745 patients with schizophrenia who were discharged from psychiatric wards and registered in a national population-based schizophrenia registry between 2005 and 2009. The proportion of patients receiving suicide risk assessment at discharge from a psychiatric ward increased from 72% (95% confidence interval [CI]=71%-74%) in 2005, when the national monitoring began, to 89% (CI=89%-90%) in 2009. Within one year after discharge, 1% of all registered patients had died by suicide and 8% had attempted suicide. One out of three patients who died by suicide had no documented suicide risk assessment before discharge. The use of systematic suicide risk assessment at discharge among patients with schizophrenia increased in Denmark between 2005 and 2009, in accordance with recommendations in national clinical guidelines and monitoring in a national clinical registry. Additional efforts are warranted to ensure a lower risk of suicidal behavior after hospital discharge.

    Deficits in social skills may present in a range of psychiatric disorders, particularly in the more serious and persistent conditions, and have an influence on functioning across various domains. This pilot study aimed at developing a brief measure, for structured evaluation and screening for social skills deficits, which can be easily integrated into routine clinical practice. The sample consisted of 380 inpatients and their accompanying caregivers, referred to Psychiatric Rehabilitation Services at a tertiary care government psychiatric hospital. The evaluation included an Inpatient intake Proforma and the 20-item Social Skills Assessment Screening Scale (SSASS). Disability was assessed using the Indian Disability Evaluation and Assessment Scale (IDEAS) for a subset of 94 inpatients. The analysis included means and standard deviations, frequency and percentages, Cronbach's alpha to assess internal consistency, t -tests to assess differences in social skills deficits between select subgroups, and correlation between SSASS and IDEAS scores. The results indicated the profile of social skills deficits assessed among the inpatients with varied psychiatric diagnoses. The "psychosis" group exhibited significantly higher deficits than the "mood disorder" group. Results indicated high internal consistency of the SSASS and adequate criterion validity demonstrated by correlations with select IDEAS domains. Modifications were made to the SSASS following the pilot study. The SSASS has potential value as a measure for screening and individualised intervention plans for social skills training in mental health and rehabilitation settings. The implications for future work on the psychometric properties and clinical applications are discussed.

    Objective Hip pain and injury as a result of activity can lead to the development of early hip osteoarthritis (OA) in susceptible individuals. Our understanding of the factors that increase susceptibility continues to evolve. The ability to clearly identify individuals (and cohorts) with activity-related hip pain who are at risk of early hip OA is currently lacking. The purpose of this study was to gain expert consensus on which key clinical measures might help predict the risk of early hip OA in individuals presenting with activity-related hip pain. The agreed measures would constitute a standardised approach to initial clinical assessment to help identify these individuals. Methods This Dephi study used online surveys to gain concordance of expert opinion in a structured process of ‘rounds’. In this study, we asked ‘What outcome measures are useful in predicting hip OA in activity-related hip pain?’ The Delphi panel consisted of experts from sport and exercise medicine, orthopaedics, rheumatology, physiotherapy and OA research. Results The study identified key clinical measures in the history, examination and investigations (plain anteroposterior radiograph and femoroacetabular impingement views) that the panel agreed would be useful in predicting future risk of hip OA when assessing activity-related hip pain. The panel also agreed that certain investigations and tests (eg, MR angiography) did not currently have a role in routine assessment. There was a lack of consensus regarding the role of MRI, patient-reported outcome measures (PROMs) and certain biomechanical and functional assessments. Conclusions We provide a standardised approach to the clinical assessment of patients with activity-related hip pain. Assessment measures rejected by the Delphi panel were newer, more expensive investigations that currently lack evidence. Assessment measures that did not reach consensus include MRI and PROMs. Their role remains ambiguous and would benefit from further

    Risk assessment of secondary soil salinization, which is caused in part by the way people manage the land, is an essential challenge to agricultural sustainability. The objective of our study was to develop a soil salinity risk assessment methodology by selecting a consistent set of risk factors based on the conceptual Pressure-State-Response (PSR) sustainability framework and incorporating the grey relational analysis and the Analytic Hierarchy Process methods. The proposed salinity risk assessment methodology was demonstrated through a case study of developing composite risk index maps for the Yinchuan Plain, a major irrigation agriculture district in northwest China. Fourteen risk factors were selected in terms of the three PSR criteria: pressure, state, and response. The results showed that the salinity risk in the Yinchuan Plain was strongly influenced by the subsoil and groundwater salinity, land use, distance to irrigation canals, and depth to groundwater. To maintain agricultural sustainability in the Yinchuan Plain, a suite of remedial and preventative actions were proposed to manage soil salinity risk in the regions that are affected by salinity at different levels and by different salinization processes. The weight sensitivity analysis results also showed that the overall salinity risk of the Yinchuan Plain would increase or decrease as the weights for pressure or response risk factors increased, signifying the importance of human activities on secondary soil salinization. Ideally, the proposed methodology will help us develop more consistent management tools for risk assessment and management and for control of secondary soil salinization.

    The current paper presents a pilot study of interactive assessment using information and communication technology (ICT) to evaluate the knowledge, skills and abilities of staff with no formal education who are working in Swedish elderly care. Theoretical and practical assessment methods were developed and used with simulated patients and computer-based tests to identify strengths and areas for personal development among staff with no formal education. Of the 157 staff with no formal education, 87 began the practical and/or theoretical assessments, and 63 completed both assessments. Several of the staff passed the practical assessments, except the morning hygiene assessment, where several failed. Other areas for staff development, i.e. where several failed (>50%), were the theoretical assessment of the learning objectives: Health, Oral care, Ergonomics, hygiene, esthetic, environmental, Rehabilitation, Assistive technology, Basic healthcare and Laws and organization. None of the staff passed all assessments. Number of years working in elderly care and staff age were not statistically significantly related to the total score of grades on the various learning objectives. The interactive assessments were useful in assessing staff members' practical and theoretical knowledge, skills, and abilities and in identifying areas in need of development. It is important that personnel who lack formal qualifications be clearly identified and given a chance to develop their competence through training, both theoretical and practical. The interactive e-assessment approach analyzed in the present pilot study could serve as a starting point.

    Digital assessments of caput succedaneum are subjective; however, caput succedaneum can also be expressed as ultrasound measured skin-skull distance (SSD). In this study, we aimed to compare the clinical and ultrasound assessment of caput succedaneum (caput) in nulliparous women in the first stage of labour. Furthermore, we aimed to investigate the repeatability of ultrasound measurements. We observed a significant but low correlation between clinical and ultrasound assessments (Kappa value 0.29; P caput measurements was -0.4 mm (95% CI, -0.85 to 0.05), and limits of agreement were -3.44 to 2.64 mm. We conclude that ultrasound measured SSD is an objective expression of caput with significant correlation with clinical assessment. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    One aspect to consider when reporting results of observational studies in epidemiology is how quantitative risk factors are analysed. The STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines recommend that researchers describe how they handle quantitative variables when analysing data. For categorised quantitative variables, the authors are required to provide reasons and justifications informing their practice. We investigated and assessed the practices and reporting of categorised quantitative variables in epidemiology. The assessment was based on five medical journals that publish epidemiological research. Observational studies published between April and June 2015 and investigating the relationships between quantitative exposures (or risk factors) and the outcomes were considered for assessment. A standard form was used to collect the data, and the reporting patterns amongst eligible studies were quantified and described. Out of 61 articles assessed for eligibility, 23 observational studies were included in the assessment. Categorisation of quantitative exposures occurred in 61% of these studies and reasons informing the practice were rarely provided. Only one article explained the choice of categorisation in the analysis. Transformation of quantitative exposures into four or five groups was common and dominant amongst studies using equally spaced categories. Dichotomisation was not popular; the practice featured in one article. Overall, the majority (86%) of the studies preferred ordered or arbitrary group categories. Other criterions used to decide categorical boundaries were based on established guidelines such as consensus statements and WHO standards. Categorisation of continuous variables remains a dominant practice in epidemiological studies. The reasons informing the practice of categorisation within published work are limited and remain unknown in most articles. The existing STROBE guidelines could provide stronger

    As urology training programs move to a competency based medical education model, iterative assessments with objective standards will be required. To develop a valid set of technical skills standards we initiated a national skills assessment study focusing initially on laparoscopic skills. Between February 2014 and March 2016 the basic laparoscopic skill of Canadian urology trainees and attending urologists was assessed using 4 standardized tasks from the AUA (American Urological Association) BLUS (Basic Laparoscopic Urological Surgery) curriculum, including peg transfer, pattern cutting, suturing and knot tying, and vascular clip applying. All performances were video recorded and assessed using 3 methods, including time and error based scoring, expert global rating scores and C-SATS (Crowd-Sourced Assessments of Technical Skill Global Rating Scale), a novel, crowd sourced assessment platform. Different methods of standard setting were used to develop pass-fail cut points. Six attending urologists and 99 trainees completed testing. Reported laparoscopic experience and training level correlated with performance (p standard setting methods to define pass-fail cut points for all 4 AUA BLUS tasks. The 4 AUA BLUS tasks demonstrated good construct validity evidence for use in assessing basic laparoscopic skill. Performance scores using the novel C-SATS platform correlated well with traditional time-consuming methods of assessment. Various standard setting methods were used to develop pass-fail cut points for educators to use when making formative and summative assessments of basic laparoscopic skill.

    Adequacy assessment for fine-needle aspiration procedures is a standard of care in large medical centers. Although the benefits of this approach include higher adequacy rates with fewer passes, it costs cytopathologist time and affects other clinical responsibilities. The objective of the current study was to evaluate the use of mobile video streaming (FaceTime) technology with the help of smartphone adapters attached to microscopes for remote adequacy assessment of cytologic samples. The study consisted of 2 phases: Phase 1 was a retrospective assessment of 25 samples by a primary pathologist with simultaneous streaming to a second pathologist using a smartphone (iPhone/iPad) FaceTime connection. Data on the adequacy of each sample and preliminary diagnoses were recorded. In phase 2, live cases were assessed prospectively by an onsite primary pathologist and by a remote pathologist using an iPhone/iPad-FaceTime connection. The testing phase involved prospective assessment of additional samples with a resident or cytotechnologist as the slide driver. In phase 1, retrospective evaluation of 25 samples yielded considerable agreement (22 of 25 samples; 88%) between onsite and remote adequacy assessments. Three samples (12%) yielded results that did not agree, including 2 samples that were read as adequate in the onsite evaluation that were assessed as indeterminate using FaceTime. In phase 2 and in the testing phase, 14 samples exhibited considerable agreement on both adequacy and preliminary diagnosis (6 samples in phase 2 and 8 samples in the testing phase) and are currently available for reporting. Problems encountered include software version standardization, camera alignment, and (rarely) comprehension of the audio stream. The current data indicate that iPhone/iPad FaceTime technology can be used to perform remote adequacy assessments of fine-needle aspirations and can help save valuable time for pathologists. © 2015 American Cancer Society.

    2010-03-01

    This paper assesses the methodology employed in longitudinal studies of advertising and youth drinking and smoking behaviors. These studies often are given a causal interpretation in the psychology and public health literatures. Four issues are examined from the perspective of econometrics. First, specification and validation of empirical models. Second, empirical issues associated with measures of advertising receptivity and exposure. Third, potential endogeneity of receptivity and exposure variables. Fourth, sample selection bias in baseline and follow-up surveys. Longitudinal studies reviewed include 20 studies of youth drinking and 26 studies of youth smoking. Substantial shortcomings are found in the studies, which preclude a causal interpretation.

    This work aims to assess the operation of the first large scale segregated biowaste composting scheme in Greece to divert Household Food Waste (HFW) from landfill and produce a material which can be recovered and used as compost. The source separation and collection of HFW was deployed in selected areas in Attica Region serving about 3700 households. Sorted HFW is collected & transported to the Mechanical and Biological Treatment (MBT) plant in Attica Region that has been designed to produce Compost Like Output (CLO) from mixed MSW. The MBT facility has been adjusted in order to receive and treat aerobically HFW mixed with shredded green waste in a dedicated composting tunnel. The composting process was monitored against temperature, moisture and oxygen content indicating that the biological conditions are sufficiently developed. The product quality was examined and assessed against the quality specifications of EU End of Waste Criteria for biowaste subjected to composting aiming to specify whether the HFW that has undergone recovery ceases to be waste and can be classified as compost. More specifically, the heavy metals concentrations (Cr, Cu, Ni, Cd, Pb, Zn and Hg) are within the set limits and much lower compared to the CLO material that currently is being produced at the MBT plant. In regard to the hygienic requirements of the product it has been found that the process conditions result in a pathogen free material (i.e. E. Coli and Salmonella) which does not favor the growth of viable weeds and plant propagules, while it acquires sufficient organic matter content for soil fertilization. Noticeable physical impurities (mainly fractions of glass) have been detected exceeding the quality control threshold limit of 0.5% w/w (plastics, metals and glass). The latter is related to the missorted materials and to the limited pre-treatment configurations prior to composting. The above findings indicate that effective source separation of biowaste is prerequisite for

    BACKGROUND Available publications provide little evidence pertaining to assessment of foot shape in children with intellectual disability. The aim of this study was to assess the parameters of foot shape in children and adolescents with intellectual disability and to evaluate the relationship between the degree of disability and these parameters. MATERIAL AND METHODS The study involved 90 individuals aged 7-15 years, including 45 subjects with mild and moderate levels of intellectual disability (study group) and 45 peers with normal intellectual development (control group). Each participant was subjected to photogrammetric assessment of foot shape based on the projection moire effect. RESULTS Analysis of the relationship between the disability level and the assessed parameters showed that the length of the right (p=0.006) and left (p=0.004) foot, as well as Wejsflog's rate for the right (p<0.001) and left (p<0.001) foot, were significantly higher among children with mild disability, whereas GAMMA angle of the right (p=0.028) and left (p=0.006) foot was significantly higher among children with moderate disability. CONCLUSIONS The findings show a significant relationship between the degree of disability and the assessed foot parameters. Significant differences between the subjects with intellectual disability and the control group were identified in the basic parameters defining foot structure.

    The occupational role of 'driver' is highly valued. Stroke can have a significant impact on an individual's ability to drive safely. Multi-disciplinary driver assessments are conducted to assess the safety of post-stroke individuals returning to driving, however, little follow-up of drivers following successful assessment has been performed. The objective of this study was to investigate whether passing a multi-disciplinary driving assessment following stroke predicted medium- to long-term safe and confident driving. A retrospective cohort study with primary data collection through structured telephone interviews was undertaken. Respondents were individuals post-stroke aged 18-74years who had successfully passed a multi-disciplinary driver assessment.  Forty-five respondents were interviewed an average of 20months following the assessment. Forty individuals were still driving. Twenty-five driving respondents reported driving in conditions that indicated confident driving. Confident driving was measured by driving frequency and distance, night driving, freeway driving and driving alone. The frequency of accidents and incidents suggests that 95% (n=38) of drivers are 'safe'. Eight respondents reported accidents, one of which was major. In two accidents the respondent was 'at fault'. A crash rate of 222 per 100,000 drivers is within the confidence interval for similar accidents in New South Wales. The results of this small cohort study suggest that a multi-disciplinary driver assessment may be effective in identifying people following stroke with the ability to drive safely and confidently. © 2011 The Authors.

    Full Text Available Abstract Background Several thousand human genome epidemiology association studies are published every year investigating the relationship between common genetic variants and diverse phenotypes. Transparent reporting of study methods and results allows readers to better assess the validity of study findings. Here, we document reporting practices of human genome epidemiology studies. Methods Articles were randomly selected from a continuously updated database of human genome epidemiology association studies to be representative of genetic epidemiology literature. The main analysis evaluated 315 articles published in 2001–2003. For a comparative update, we evaluated 28 more recent articles published in 2006, focusing on issues that were poorly reported in 2001–2003. Results During both time periods, most studies comprised relatively small study populations and examined one or more genetic variants within a single gene. Articles were inconsistent in reporting the data needed to assess selection bias and the methods used to minimize misclassification (of the genotype, outcome, and environmental exposure or to identify population stratification. Statistical power, the use of unrelated study participants, and the use of replicate samples were reported more often in articles published during 2006 when compared with the earlier sample. Conclusion We conclude that many items needed to assess error and bias in human genome epidemiology association studies are not consistently reported. Although some improvements were seen over time, reporting guidelines and online supplemental material may help enhance the transparency of this literature.

    Phenomenon: As we move toward competency-based medical education, greater emphasis is being placed on assessing a more comprehensive skill set, including the ability to communicate and collaborate effectively in the workplace. Nonphysician members on interprofessional (IP) teams have valuable perspectives on actual resident performance and are often not adequately engaged in the provision of feedback to residents. Based on the educational theories of collaborative evaluation and social constructivism, this research examined the ability of IP clinicians to provide feedback to residents. The aim of this study was to examine IP clinicians' perceptions of their ability to provide formative feedback, through their observations and assessments of developmental pediatric residents, compared to physician supervisors on the rotation, and to qualitatively explore potential barriers to the feedback process from their perspective. This explanatory, sequential mixed-methods design study first examined which and how many of the CanMEDS Communicator and Collaborator training objectives (N = 40) were considered to be observable and assessable by IP clinicians and physicians. A comparison of the mean number of objectives that were observed and practically assessed by (a) each group (IP clinicians vs. physicians) and (b) clinical service teams during the core developmental pediatrics rotations, were examined using independent t tests. Second, a thematic qualitative analysis of focus groups was used to develop a contextual understanding of the factors that influenced this process. Data were analyzed using three levels of open coding and descriptive qualitative analysis techniques. Physicians reported they could observe (M = 33.3, SD = 5.2, 83.3%) and assess (M = 31.5, SD = 7.3, 79%) a larger number of objectives compared to the IP clinician group (M = 24.7, SD = 8.6, 61.8% and M = 20.3, SD = 10.6, 51%, respectively). There were no differences between the clinical service teams (i

    To present the pilot study on the European Portuguese validation of the Confusion Assessment Method (CAM). The translation process was carried out according to International Society Pharmacoeconomics and Outcomes Research guidelines with trained researchers and inter-rater reliability assessment. The study included 50 elderly patients, admitted (≥24 h) to two intermediate care units. Exclusion criteria were: Glasgow Coma Scale (total score ≤11), blindness/deafness, inability to communicate and not able to speak Portuguese. The sensitivity and specificity of CAM were assessed, with DSM-IV-TR criteria of delirium used as a reference standard. Findings revealed excellent inter-rater reliability (k>0.81), moderate sensitivity (73%) and excellent specificity (95%). These preliminary results suggested that this version emerges as a promising diagnostic instrument for delirium.

    Full Text Available Abstract Background Alcohol causes huge problems for population health and for society, which require interventions with individuals as well as populations to prevent and reduce harms. Brief interventions can be effective and increasingly take advantage of the internet to reach high-risk groups such as students. The research literature on the effectiveness of online interventions is developing rapidly and is confronted by methodological challenges common to other areas of e-health including attrition and assessment reactivity and in the design of control conditions. Methods/design The study aim is to evaluate the effectiveness of a brief online intervention, employing a randomized controlled trial (RCT design that takes account of baseline assessment reactivity, and other possible effects of the research process. Outcomes will be evaluated after 3 months both among student populations as a whole including for a randomized no contact control group and among those who are risky drinkers randomized to brief assessment and feedback (routine practice or to brief assessment only. A three-arm parallel groups trial will also allow exploration of the magnitude of the feedback and assessment component effects. The trial will be undertaken simultaneously in 2 universities randomizing approximately 15,300 students who will all be blinded to trial participation. All participants will be offered routine practice intervention at the end of the study. Discussion This trial informs the development of routine service delivery in Swedish universities and more broadly contributes a new approach to the study of the effectiveness of online interventions in student populations, with relevance to behaviors other than alcohol consumption. The use of blinding and deception in this study raise ethical issues that warrant further attention. Trial registration ISRCTN28328154

    Remote assessments of individuals with a neurological disease via telemedicine have the potential to reduce some of the burdens associated with clinical care and research participation. We aim to evaluate the feasibility of conducting the Montreal Cognitive Assessment remotely in individuals with movement disorders. A pilot study derived from two telemedicine trials was conducted. In total, 17 individuals with movement disorders (8 with Parkinson disease and 9 with Huntington disease) had Montreal Cognitive Assessment examinations evaluated in-person and remotely via web-based video conferencing to primarily determine feasibility and potential barriers in its remote administration. Administering the Montreal Cognitive Assessment remotely in a sample of movement disorder patients with mild cognitive impairment is feasible, with only minor common complications associated with technology, including delayed sound and corrupted imaging for participants with low connection speeds. The Montreal Cognitive Assessment has the potential to be used in remote assessments of patients and research participants with movement disorders. © The Author(s) 2014.

    2015-04-01

    Full Text Available The fact that the United Nations (UN Trafficking Protocol is not an autochthonous product of the Brazilian political system has resulted in its being brought into that system as a ‘floating signifier’: something that does not point to any actual object or agreed upon meaning.[1] People who wish to criminalise prostitution have attempted to bend the Protocol in that direction while prostitutes’ rights groups have used it to critique current Brazilian laws, emphasising the need to distinguish migration for voluntary, consensual sex work from trafficking. Groups concerned with organ trafficking (a crime for which there are practically no proven cases in Brazil have managed to push their banner to the fore in the trafficking debate. Meanwhile, Brazil’s long-established and relatively successful anti-slave labour movement has been loath to ‘change their brand’, having already gained a considerable degree of institutionalisation prior to Brazil’s ratification of the Protocol in 2004.

    Full Text Available How does women’s participation in sport contribute to the re-signification of women’s corporality? Considering Susan Brownmiller’s notion that femininity, in modern society, can be understood as an “aesthetic of limitation”, I also work with notions of gender and corporality taken from recent work by Susan Bordo and Judith Butler, in an attempt to identify changes in women’s practices and representations of the female body propitiated by sporting activity. I analyze the testimonies of Brazilian women athletes, most of whom can be considered professionals, from two sporting fields: on the one hand, equestriennes engaged in the elite sport of showjumping, and on the other, women involved in the popular sport of volleyball. I also look at cultural images of women athletes as currently produced in mass media. he evidence that I obtain through field work leads me to identify conflicting tendencies of “deconstruction” of certain aspects of the above-mentioned aesthetics of limitation and persistent cultural concern for women’s “masculinization” through sport.

    Full Text Available Marked by the scientific discovery of atomic energy, the nuclear age, which spans the twentieth century, has changed the nature of culture as well as the landscape. Despite recent talks on nuclear disarmament, the dread of nuclear arms production, proliferation, and waste storage is pervasive at both global and local levels, haunting governments, communities, and individuals alike. Nuclear sites concern not only scientists and politicians but also environmental designers. The need to evoke a cultural discourse, protect future generations, reveal or conceal radioactive burial sites, and recycle retired installations engenders the participation of artists and designers. How do designers intersect with these hellish places? Do we have a potent role in addressing this conundrum? In what follows, I confront the consumption and design of today’s most daunting places - the landscapes of nuclear and radioactive material production, processing, testing, and burial.

  3. Fictionalized History: Signifying Changes to the Malaysian Nation and Identity

    Full Text Available As one of the cornerstones of fiction, writers often use and confront history in their claim to “reality” and “identity” in their writing. Linda Hutcheon’s claim for “a postmodern concern for the multiplicity and dispersion of truth(s; truth(s relative to the specificity of place and culture” (1988, p. 108 is relevant to the use of history in recent Malaysian literature. The multiple and varied claims of truth(s as reflected through the fictionalizing of Malaysian history is the focus of the analysis in this article, which aims to expose the social, economic, and political implications of the Malaysian identity. The analysis of three current works of fictionalized Malaysian history from the different fictional genres of comic series, children’s history, and occidental history, represents a cross section of genres that challenge the supremacy of history’s ontological claim over identity. The deliberate contestation of received Malaysian history in fictional modes acknowledges the peripheral identity structures of race, religion, and economics that are sensitive in a multiracial country such as Malaysia.

    2012-08-01

    Full Text Available Abstract Electronic health records serve multiple purposes, including clinical communication, legal documentation, financial transaction capture, research and analytics. Electronic signatures attached to entries in EHRs have different logical and legal meanings for different users. Some of these are vestiges from historic paper formats that require reconsideration. Traditionally accepted functions of signatures, such as identity verification, attestation, consent, authorization and non-repudiation can become ambiguous in the context of computer-assisted workflow processes that incorporate functions like logins, auto-fill and audit trails. This article exposes the incompatibility of expectations among typical users of electronically signed information.

    This report describes the baseline experience of the multicenter, Home-Based Assessment study, designed to develop methods for dementia prevention trials using novel technologies for test administration and data collection. Nondemented individuals of 75 years of age or more were recruited and evaluated in-person using established clinical trial outcomes of cognition and function, and randomized to one of 3 assessment methodologies: (1) mail-in questionnaire/live telephone interviews [mail-in/phone (MIP)]; (2) automated telephone with interactive voice recognition; and (3) internet-based computer Kiosk. Brief versions of cognitive and noncognitive outcomes were adapted to each methodology and administered at baseline and repeatedly over a 4-year period. "Efficiency" measures assessed the time from screening to baseline, and staff time required for each methodology. A total of 713 individuals signed consent and were screened; 640 met eligibility and were randomized to one of 3 assessment arms; and 581 completed baseline. Dropout, time from screening to baseline, and total staff time were highest among those assigned to internet-based computer Kiosk. However, efficiency measures were driven by nonrecurring start-up activities suggesting that differences may be mitigated over a long trial. Performance among Home-Based Assessment instruments collected through different technologies will be compared with established outcomes over this 4-year study.

  11. Results of the Weeks Island Strategic Petroleum Reserve Oil Leak Risk Assessment Study

    Molecke, M.A.; Hinkebein, T.E.; Bauer, S.J.; Linn, J.K.

    1998-12-01

    This study evaluated multiple, long-term environmental oil-contamination risk scenarios that could result from the potential leakage of UP to 1.5 million barrels of crude oil entombed in the Weeks Island SPR mine following site decommissioning and abandonment, and up to 100 years thereafter. This risk assessment also provides continuity with similar risk evaluations performed earlier and documented in the 1995 DOE Environmental Assessment for Decommissioning the Strategic Petroleum Reserve Weeks Island Facility (EA). This current study was requested by the DOE to help them determine if their previous Finding of No Significant Impact (FONSI), in the EA, is still valid or needs to be rescinded. Based on the calculated environmental risk results (in terms of clean-up and remediation expenses) presented in this risk assessment, including the calculated average likelihoods of oil release and potential oil-leakage volumes, none of the evaluated risk events would appear to satisfy the definition of significant environmental impact in National Environmental Policy Act (NEPA) terminology. The DOE may combine these current results with their earlier evaluations and interpretations in the 1995 EA in order to assess whether the existing FONSI is still accurate, acceptable, and valid. However, from a risk evaluation standpoint, the assessment of impacts appears to be the same whether only 10,000 to 30,000 barrels of crude oil (as considered in the 1995 EA), or up to 1.5 million barrels of oil (as considered herein) are abandoned in the Weeks Island SPR facility

  12. The human component of sustainability: a study for assessing "human performances" of energy efficient construction blocks.

    Attaianese, Erminia; Duca, Gabriella

    2012-01-01

    This paper presents an applied research aimed at understanding the relevance and the applicability of human related criteria in sustainability assessment of construction materials. Under a theoretical perspective, human factors consideration is strongly encouraged by building sustainability assessment methods, but the practice demonstrates that current models for building sustainability assessment neglect ergonomic issues, especially those ones concerning the construction phase. The study starts from the observation that new construction techniques for high energy efficient external walls are characterized by elements generally heavier and bigger than traditional materials. In this case, high sustainability performances connected with energy saving could be reached only consuming high, and then not very much sustainable, human efforts during setting-up operations. The paper illustrates a practical approach for encompassing human factors in sustainability assessment of four block types for energy efficient external walls. Research steps, from block selections to bricklaying task analysis, human factors indicators and metrics formulation, data gathering and final assessment are going to be presented. Finally, open issues and further possible generalizations from the particular case study will be discussed.

  13. Deep assessment: an exploratory study of game-based, multimodal learning in Epidemic

    Directory of Open Access Journals (Sweden)

    Jennifer Jenson

    2016-03-01

    Full Text Available n this study, we examine what and how intermediate age students learned from playing in a health-focused game-based digital learning environment, Epidemic. Epidemic is a playful interactive environment designed to deliver factual knowledge, invite critical understanding, and encourage effective self-care practices in dealing with viral contagious diseases, using a social networking interface to integrate both serious games and game-like multimodal design projects. Epidemic invites a playful approach to its deadly serious core concern – communicable disease – in order to see what happens when students are encouraged to critically approach information from multiple or contradictory perspectives. To identify what participants learned while interacting within Epidemic, we deployed two instructional and assessment models, noting the differences each instructional approach could potentially make, and what approach to assessment might help us evaluate game-based learning. We found that each approach provided importantly different perspectives on what and how students learned, and on the very meaning of student success. Recognizing that traditional assessment tools based in print-cultural literacy may prove increasingly ill-suited for assessing emergent multimodal literacies in game-based learning environments, this study seeks to contribute to a growing body of work on the development of novel assessments for learning.

    Objective The aim of the study was to measure the effects on levels of anxiety in healthy teenagers caused by a temporary change of country and school during a study abroad program. Methods In a prospective study we gathered the data from six anxiety level related tests on high school participants in a study abroad program (age 15-17, n = 364, M 172, F 192). These volunteer participants were divided into two separate groups: with self-reported elevated levels of anxiety (n = 111; YES-group) and with self-reported normal levels of anxiety (n = 253; NO-group). Two control groups of schoolchildren drawn from two local schools were used for comparison (n = 100 each). Three tests were subjective, i.e. self-fill-out tests. The next three tests were objective psychological or neurophysiological tests designed to estimate reflex control, concentration and a feeling for the passage of time. Results The initial mean anxiety level score among the 364 participants was 41.5 ± 16.7 (min 16, max 80) on 5-110 scale. For the YES-group the score was 56.5 ± 15.9, and for the NO-group the score was 34.7 ± 17.4 (p = 0.05). The retesting after they had been in the same place for 7 weeks revealed that the mean anxiety level score of the participants decreased to 37.4 ± 16.9 (min 15, max 72). For the YES-group the score significantly decreased to 39.3 ± 15.5, and for the NO-group the score slightly elevated to 36.7 ± 16.4 producing similar results for both groups (p = 0.81). Conclusion A temporary change of country and school at first results in a rise in anxiety levels in about one third of participants. However, after an extended stay it falls to normal levels.

    2017-11-01

    Full Text Available There is a growing demand for assessment instruments which can be used in higher education, which cover a broader area of competencies than the traditional tests for disciplinary knowledge and domain-specific skills, and which measure students' most important general cognitive capabilities. Around the age of the transition from secondary to tertiary education, such assessments may serve several functions, including selecting the best-prepared candidates for certain fields of study. Dynamic problem-solving (DPS is a good candidate for such a role, as tasks that assess it involve knowledge acquisition and knowledge utilization as well. The purpose of this study is to validate an online DPS test and to explore its potential for assessing students' DPS skills at the beginning of their higher education studies. Participants in the study were first-year students at a major Hungarian university (n = 1468. They took five tests that measured knowledge from their previous studies: Hungarian language and literature, mathematics, history, science and English as a Foreign Language (EFL. A further, sixth test based on the MicroDYN approach, assessed students' DPS skills. A brief questionnaire explored learning strategies and collected data on students' background. The testing took place at the beginning of the first semester in three 2-h sessions. Problem-solving showed relatively strong correlations with mathematics (r = 0.492 and science (r = 0.401, and moderate correlations with EFL (r = 0.227, history (r = 0.192, and Hungarian (r = 0.125. Weak but still significant correlations were found with certain learning strategies, positive correlations with elaboration strategies, and a negative correlation with memorization strategies. Significant differences were observed between male and female students; men performed significantly better in DPS than women. Results indicated the dominant role of the first phase of solving dynamic problems, as knowledge

The aim of this study was to assess the visual impact on the skin of repeated ultraviolet-A (UVA exposure through a window.Methods: Eight women and two men presenting with asymmetric signs of photoaging due to overexposure of one side of their face to the sun through a window over a long period of time were enrolled in the study. Split-face biometrologic assessments were performed (clinical scoring, hydration with Corneometer®, mechanical properties with a Cutometer®, transepidermal water loss with AquaFlux®, skin relief with fringe projection, photography, stripping, and then lipid peroxidation analyses.Results: Significant differences were observed in clinical scores for wrinkles, skin roughness assessed by fringe projection on the cheek, and skin heterogeneity assessed with spectrocolorimetry on the cheekbone. Other differences were observed for skin hydration, as well as skin laxity, which tended towards significance.Discussion: This study suggests the potential benefit of daily UVA protection during nondeliberate exposure indoors as well as outside.Keywords: UVA, asymmetry, photodamage, face
