    To test the effect of an Appreciative Inquiry (AI) quality improvement strategy on clinical quality management and practice development outcomes. Appreciative inquiry enables the discovery of shared motivations, envisioning a transformed future, and learning around the implementation of a change process. Thirty diverse primary care practices were randomly assigned to receive an AI-based intervention focused on a practice-chosen topic and on improving preventive service delivery (PSD) rates. Medical-record review assessed change in PSD rates. Ethnographic field notes and observational checklist analysis used editing and immersion/crystallization methods to identify factors affecting intervention implementation and practice development outcomes. The PSD rates did not change. Field note analysis suggested that the intervention elicited core motivations, facilitated development of a shared vision, defined change objectives, and fostered respectful interactions. Practices most likely to implement the intervention or develop new practice capacities exhibited 1 or more of the following: support from key leader(s), a sense of urgency for change, a mission focused on serving patients, health care system and practice flexibility, and a history of constructive practice change. An AI approach and enabling practice conditions can lead to intervention implementation and practice development by connecting individual and practice strengths and motivations to the change objective.

    We have collaborated with two planetaria, Fernbank Science Center's Jim Cherry planetarium in Atlanta, Georgia and the Von Braun Planetarium in Huntsville, Alabama to enhance the appreciation of various astronomical topics among Girl Scouts. Major events sponsored by our partnership were sleepovers in the planetaria during which we studied the total solar eclipse of June 2001 and observed the Eta Aquarid meteor shower of May 2003. Other events included programs on stellar spectroscopy and space physics. As an added inducement for participation, we have sponsored the production of "pins", which Girl Scouts can earn after satisfying specific requirements. This poster will show samples of the pins, requirements, and online resources for the Girl Scouts.

  5. An appreciation of the events, models and data used for LMFBR radiological source term estimations

    1989-01-01

    In this report, the events, models and data currently available for analysis of accident source terms in liquid metal cooled fast neutron reactors are reviewed. The types of hypothetical accidents considered are the low probability, more extreme types of severe accident, involving significant degradation of the core and which may lead to the release of radionuclides. The base case reactor design considered is a commercial scale sodium pool reactor of the CDFR type. The feasibility of an integrated calculational approach to radionuclide transport and speciation (such as is used for LWR accident analysis) is explored. It is concluded that there is no fundamental obstacle, in terms of scientific data or understanding of the phenomena involved, to such an approach. However this must be regarded as a long-term goal because of the large amount of effort still required to advance development to a stage comparable with LWR studies. Particular aspects of LMFBR severe accident phenomenology which require attention are the behaviour of radionuclides during core disruptive accident bubble formation and evolution, and during the less rapid sequences of core melt under sodium. The basic requirement for improved thermal hydraulic modelling of core, coolant and structural materials, in these and other scenarios, is highlighted as fundamental to the accuracy and realism of source term estimations. The coupling of such modelling to that of radionuclide behaviour is seen as the key to future development in this area

  8. Musical appreciation

    2002-11-01

    Pre-school listening to music is the principal way that leads to the appreciation of music that later facilitates knowledge and pleasure in the history of music. At the prescholastic age it is a very important aspect of education, and reasons and suggestions will be given. The activities must be brief, the teachers of music can at the most develop the activity every five minutes, leaving time for rest or expansion. Another suitable way to bring the child to music is through stories, which please all children; let them go to an unreal and fantastic world and listen to a story or an exciting adventure. The story then, should be brief, simple, with action, with familiar characters, but with some mystery; some repetitive element; and an ending both surprising and happy. It is preferable to include small folkloric tales from the universal repertoire, with works of simple and clear structure.

    Full Text Available In this research the 5D-framework of Appreciative Inquiry is used to investigate the possibility of applying the attributes and artistic strategies of the pop singer Neil Diamond for the improvement of classroom practices of educationalists. During the attendance of the performances of Diamond in 2011 in South Africa the writers and five other educationalists have identified five broad qualities and practices of Diamond. These may have application value in a school or university classroom: passionate enthusiasm, purposeful dedication, communication and interaction with the audience, refusing to conform/creating variation as well as good planning. This is the first time that the 5D-cycle has been used to study the possible utilisation of a live performance of a popular artist to facilitate the professional development of educationalists.

    Full Text Available Background: Infections acquired during childbirth are a common cause of maternal and perinatal mortality and morbidity. Changing provider behaviour and organisational settings within the health system is key to reducing the spread of infection. Objective: To explore the opinions of health personnel on health system factors related to infection control and their perceptions of change in a sample of hospital maternity units. Design: An organisational change process called ‘appreciative inquiry’ (AI was introduced in three maternity units of hospitals in Gujarat, India. AI is a change process that builds on recognition of positive actions, behaviours, and attitudes. In-depth interviews were conducted with health personnel to elicit information on the environment within which they work, including physical and organisational factors, motivation, awareness, practices, perceptions of their role, and other health system factors related to infection control activities. Data were obtained from three hospitals which implemented AI and another three not involved in the intervention. Results: Challenges which emerged included management processes (e.g. decision-making and problem-solving modalities, human resource shortages, and physical infrastructure (e.g. space, water, and electricity supplies. AI was perceived as having a positive influence on infection control practices. Respondents also said that management processes improved although some hospitals had already undergone an accreditation process which could have influenced the changes described. Participants reported that team relationships had been strengthened due to AI. Conclusion: Technical knowledge is often emphasised in health care settings and less attention is paid to factors such as team relationships, leadership, and problem solving. AI can contribute to improving infection control by catalysing and creating forums for team building, shared decision making and problem solving in an

  11. Conducting Focus Groups in Terms of an Appreciation of Indigenous Ways of Knowing: Some Examples from South Africa

    Norma Ruth Arlene Romm

    2014-11-01

    Full Text Available In this article I consider some examples of conducting focus groups in South Africa with school teachers in a manner which takes into account indigenous ways of knowing. Indigenous knowing (within various indigenous cultural heritages can be defined as linked to processes of people collectively constructing their understandings by experiencing their social being in relation to others. I indicate how the conduct of focus groups can be geared towards taking into account as well as strengthening knowing as a relational activity defined in this way. Once facilitators of focus groups appreciate this epistemology they can set up a climate in which people feel part of a research process of relational discussion around issues raised. This requires an effort on the part of facilitators to make explicit to participants the type of orientation to research that is being encouraged via the focus group session. I offer examples of attempts to practice such an approach to facilitation, including examples of feedback obtained from participants regarding their experience of the research process.

  13. Dynamics of aesthetic appreciation

    Science.gov (United States)

    Carbon, Claus-Christian

    2012-03-01

    Aesthetic appreciation is a complex cognitive processing with inherent aspects of cold as well as hot cognition. Research from the last decades of empirical has shown that evaluations of aesthetic appreciation are highly reliable. Most frequently, facial attractiveness was used as the corner case for investigating aesthetic appreciation. Evaluating facial attractiveness shows indeed high internal consistencies and impressively high inter-rater reliabilities, even across cultures. Although this indicates general and stable mechanisms underlying aesthetic appreciation, it is also obvious that our taste for specific objects changes dynamically. Aesthetic appreciation on artificial object categories, such as fashion, design or art is inherently very dynamic. Gaining insights into the cognitive mechanisms that trigger and enable corresponding changes of aesthetic appreciation is of particular interest for research as this will provide possibilities to modeling aesthetic appreciation for longer durations and from a dynamic perspective. The present paper refers to a recent two-step model ("the dynamical two-step-model of aesthetic appreciation"), dynamically adapting itself, which accounts for typical dynamics of aesthetic appreciation found in different research areas such as art history, philosophy and psychology. The first step assumes singular creative sources creating and establishing innovative material towards which, in a second step, people adapt by integrating it into their visual habits. This inherently leads to dynamic changes of the beholders' aesthetic appreciation.

    2015-01-01

    Recreational music exposure is a potential risk factor for noise-induced hearing loss (NIHL). Augmented hearing protectors have been designed with modified attenuation characteristics to combine hearing protection and listening comfort. However, to date, only a few independent studies have assessed the performance of those augmented protectors in realistic exposure conditions. This study compares the listening experience and temporary effects on cochlear status with different types of earplugs after exposure to contemporary club music. Five different types of commercially available hearing protectors were worn, all commonly used during leisure-time music exposure. Four of them were augmented premolded earplugs and the fifth type was an inexpensive, standard earplug frequently distributed for free at music events. During five different test sessions of 30 min each, participants not professionally involved in music wore one particular type of protector. Contemporary club music was played at sound pressure levels (SPLs) representative of concerts and bars. After each listening session, a questionnaire on sound quality and general appreciation was completed. In addition, otoacoustic emissions (OAEs) were measured directly before and after music exposure. The reported appreciation clearly differed depending on the addressed characteristics and the specific earplug type. In this test group, the reported appreciation mainly depended on comfort and looks, while differences in sound quality were less noticeable. The changes in OAE amplitude before and after noise exposure were small in terms of clinical standards. Nevertheless, the observed temporary shifts differed systematically for the different types of hearing protectors, with two types of musician earplug showing a more systematic decline than the others. Further research with respect to actual use and achieved protection for real, unsupervised music exposure is warranted.

    2010-03-01

    Full Text Available Abstract Background Identification of terms is essential for biomedical text mining.. We concentrate here on the use of vocabularies for term identification, specifically the Unified Medical Language System (UMLS. To make the UMLS more suitable for biomedical text mining we implemented and evaluated nine term rewrite and eight term suppression rules. The rules rely on UMLS properties that have been identified in previous work by others, together with an additional set of new properties discovered by our group during our work with the UMLS. Our work complements the earlier work in that we measure the impact on the number of terms identified by the different rules on a MEDLINE corpus. The number of uniquely identified terms and their frequency in MEDLINE were computed before and after applying the rules. The 50 most frequently found terms together with a sample of 100 randomly selected terms were evaluated for every rule. Results Five of the nine rewrite rules were found to generate additional synonyms and spelling variants that correctly corresponded to the meaning of the original terms and seven out of the eight suppression rules were found to suppress only undesired terms. Using the five rewrite rules that passed our evaluation, we were able to identify 1,117,772 new occurrences of 14,784 rewritten terms in MEDLINE. Without the rewriting, we recognized 651,268 terms belonging to 397,414 concepts; with rewriting, we recognized 666,053 terms belonging to 410,823 concepts, which is an increase of 2.8% in the number of terms and an increase of 3.4% in the number of concepts recognized. Using the seven suppression rules, a total of 257,118 undesired terms were suppressed in the UMLS, notably decreasing its size. 7,397 terms were suppressed in the corpus. Conclusions We recommend applying the five rewrite rules and seven suppression rules that passed our evaluation when the UMLS is to be used for biomedical term identification in MEDLINE. A software

    2009-04-01

    The Sabin oral polio vaccine (OPV) may evolve into pathogenic viruses, causing sporadic cases and outbreaks of poliomyelitis. Such vaccine-derived polioviruses (VDPV) generally exhibit altered antigenicity. The current paradigm to distinguish VDPV from OPV and wild polioviruses is to characterize primarily those poliovirus isolates that demonstrate deviations from OPV in antigenic and genetic intratypic differentiation (ITD) tests. Here we report on two independent cases of poliomyelitis caused by VDPVs with "Sabin-like" properties in several ITD assays. The results suggest the existence of diverse pathways of OPV evolution and necessitate improvement of poliovirus surveillance, which currently potentially misses this class of VDPV.

    2013-08-01

    Amid tremendous changes in contemporary health care stimulated by shifts in social, economic and political environments, health care managers are challenged to provide new structures and processes to continually improve health service delivery. The general public and the media are becoming less tolerant of poor levels of health care, and health care professionals need to be involved and supported to bring about positive change in health care. Appreciative inquiry (AI) is a philosophy and method for promoting transformational change, shifting from a traditional problem-based orientation to a more strength-based approach to change, that focuses on affirmation, appreciation and positive dialog. This paper discusses how an innovative participatory approach such as AI may be used to promote workforce engagement and organizational learning, and facilitate positive organizational change in a health care context.

The study of literature can be used as a channel for college students to access a wealth of human experience and to develop their sensitivity, empathy, and compassion toward other human beings. However, most ESL students in Taiwan are used to following their teachers’ interpretations and lack the confidence or experience to use their hearts to appreciate literature works. Appreciative pedagogy can be used in teaching literature. Through using the steps of the Discovery-DreamDesign-Delivery cycle designed by Cooperrider and Whitney (1999 in the practice of appreciative pedagogy, students can form a positive attitude towards their characteristics, values, and past experiences, thereby developing their self-confidence and competencies in studying literature. The quantitative instruments used were an English reading proficiency test and a student satisfaction survey. A fourteen-week experiment was conducted to evaluate the effectiveness of using appreciative pedagogy with ESL students studying literature. The research results revealed that students instructed with appreciative pedagogy had improved English reading proficiency and greater satisfaction with their class.

  1. Improving creativity performance by short-term meditation

    Science.gov (United States)

    2014-01-01

    Background One form of meditation intervention, the integrative body-mind training (IBMT) has been shown to improve attention, reduce stress and change self-reports of mood. In this paper we examine whether short-term IBMT can improve performance related to creativity and determine the role that mood may play in such improvement. Methods Forty Chinese undergraduates were randomly assigned to short-term IBMT group or a relaxation training (RT) control group. Mood and creativity performance were assessed by the Positive and Negative Affect Schedule (PANAS) and Torrance Tests of Creative Thinking (TTCT) questionnaire respectively. Results As predicted, the results indicated that short-term (30 min per day for 7 days) IBMT improved creativity performance on the divergent thinking task, and yielded better emotional regulation than RT. In addition, cross-lagged analysis indicated that both positive and negative affect may influence creativity in IBMT group (not RT group). Conclusions Our results suggested that emotion-related creativity-promoting mechanism may be attributed to short-term meditation. PMID:24645871

    The program developed by KAERI for source term assessment of radwastes from the advanced nuclear fuel cycle consists of spent fuel database analysis module, spent fuel arising projection module, and automatic characterization module for radwastes from pyroprocess. To improve the algorithm adopted the developed program, following items were carried out: - development of an algorithm to decrease analysis time for spent fuel database - development of setup routine for a analysis procedure - improvement of interface for spent fuel arising projection module - optimization of data management algorithm needed for massive calculation to estimate source terms of radwastes from advanced fuel cycle The program developed through this study has a capability to perform source term estimation although several spent fuel assemblies with different fuel design, initial enrichment, irradiation history, discharge burnup, and cooling time are processed at the same time in the pyroprocess. It is expected that this program will be very useful for the design of unit process of pyroprocess and disposal system

    The Fish by Marianne Moore was published in 1921 and this poem leaves large space for the readers to conduct comprehensive interpretation. A couple of significant aspects of the poem are well worth discussing and appreciating. In this paper, the poem will be summarized in a way of story-telling and some indispensable elements of the poem will be analyzed in detail. First, the structure of the poem will be analyzed from two perspectives: the disordered arrangement of the lines and the missing of the subject. Besides, the metre of the poem will be analyzed: strict rhyme scheme and alliteration.What’s more, the figure of speech applied in the poem needs to be paid more attention: simile, metaphor and personification. In particular, the contrast of colors in this poem will be studied: darkness and colorfulness. Last but not least, the theme of the poem is opening and three themes will be discussed: life and death, natural disaster and man-made damage, the symbiosis.

  4. Analytical Sociology: A Bungean Appreciation

    Science.gov (United States)

    Wan, Poe Yu-ze

    2012-10-01

    Analytical sociology, an intellectual project that has garnered considerable attention across a variety of disciplines in recent years, aims to explain complex social processes by dissecting them, accentuating their most important constituent parts, and constructing appropriate models to understand the emergence of what is observed. To achieve this goal, analytical sociologists demonstrate an unequivocal focus on the mechanism-based explanation grounded in action theory. In this article I attempt a critical appreciation of analytical sociology from the perspective of Mario Bunge's philosophical system, which I characterize as emergentist systemism. I submit that while the principles of analytical sociology and those of Bunge's approach share a lot in common, the latter brings to the fore the ontological status and explanatory importance of supra-individual actors (as concrete systems endowed with emergent causal powers) and macro-social mechanisms (as processes unfolding in and among social systems), and therefore it does not stipulate that every causal explanation of social facts has to include explicit references to individual-level actors and mechanisms. In this sense, Bunge's approach provides a reasonable middle course between the Scylla of sociological reification and the Charybdis of ontological individualism, and thus serves as an antidote to the untenable "strong program of microfoundations" to which some analytical sociologists are committed.

    2017-02-01

    The practice of medicine, and also medical education, typically adopts a problem-solving approach to identify "what is going wrong" with a situation. However, an alternative is Appreciative Inquiry (AI), which adopts a positive and strengths-based approach to identify "what is going well" with a situation. The AI approach can be used for the development and enhancement of the potential of both individuals and organizations. An essential aspect of the AI approach is the generative process, in which a new situation is envisioned and both individual and collective strengths are mobilized to make changes to achieve the valued future situation. The AI approach has been widely used in the world of business and general education, but is has an exciting potential for medical education, including curriculum development, faculty development, supporting learners through academic advising and mentoring, but also for enhancing the teaching and learning of both individuals and groups. This AMEE Guide describes the core principles of AI and their practical application in medical education.

    2011-01-01

    An improvement of Tone's method, which is a resonance calculation method based on the equivalence theory, is proposed. In order to increase calculation accuracy, the two-term rational approximation is incorporated for the representation of neutron flux. Furthermore, some theoretical aspects of Tone's method, i.e., its inherent approximation and choice of adequate multigroup cross section for collision probability estimation, are also discussed. The validity of improved Tone's method is confirmed through a verification calculation in an irregular lattice geometry, which represents part of an LWR fuel assembly. The calculation result clarifies the validity of the present method. (author)

  7. MUSIC APPRECIATION AND TRAINING FOR COCHLEAR IMPLANT RECIPIENTS: A REVIEW

    Looi, Valerie; Gfeller, Kate; Driscoll, Virginia

    2012-01-01

    In recent years, there has been increasing interest in music perception of cochlear implant (CI) recipients, and a growing body of research conducted in this area. The majority of these studies have examined perceptual accuracy for pitch, rhythm, and timbre. Another important, but less commonly studied aspect of music listening is appreciation, or appraisal. Despite the ongoing research into potential technological improvements that may improve music perception for recipients, both perceptual accuracy and appreciation generally remain poor for most recipients. Whilst perceptual accuracy for music is important, appreciation and enjoyment also warrants research as it also contributes to clinical outcomes and perceived benefits. Music training is being shown to offer excellent potential for improving music perception and appreciation for recipients. Therefore, the primary topics of this review are music appreciation and training. However, a brief overview of the psychoacoustic, technical, and physiological factors associated with a recipient’s perception of music is provided, as these are important factors in understanding the listening experience for CI recipients. The purpose of this review is to summarize key papers that have investigated these issues, in order to demonstrate that i) music enjoyment and appraisal is an important and valid consideration in evaluating music outcomes for recipients, and ii) that music training can improve music listening for many recipients, and is something that can be offered to persons using current technology.

  8. Working memory training improves visual short-term memory capacity.

    2016-01-01

    Since antiquity, philosophers, theologians, and scientists have been interested in human memory. However, researchers today are still working to understand the capabilities, boundaries, and architecture. While the storage capabilities of long-term memory are seemingly unlimited (Bahrick, J Exp Psychol 113:1-2, 1984), working memory, or the ability to maintain and manipulate information held in memory, seems to have stringent capacity limits (e.g., Cowan, Behav Brain Sci 24:87-185, 2001). Individual differences, however, do exist and these differences can often predict performance on a wide variety of tasks (cf. Engle What is working-memory capacity? 297-314, 2001). Recently, researchers have promoted the enticing possibility that simple behavioral training can expand the limits of working memory which indeed may also lead to improvements on other cognitive processes as well (cf. Morrison and Chein, Psychol Bull Rev 18:46-60 2011). However, initial investigations across a wide variety of cognitive functions have produced mixed results regarding the transferability of training-related improvements. Across two experiments, the present research focuses on the benefit of working memory training on visual short-term memory capacity-a cognitive process that has received little attention in the training literature. Data reveal training-related improvement of global measures of visual short-term memory as well as of measures of the independent sub-processes that contribute to capacity (Awh et al., Psychol Sci 18(7):622-628, 2007). These results suggest that the ability to inhibit irrelevant information within and between trials is enhanced via n-back training allowing for selective improvement on untrained tasks. Additionally, we highlight a potential limitation of the standard adaptive training procedure and propose a modified design to ensure variability in the training environment.

  10. Fiscal terms for gas need improvement in many countries

    International Nuclear Information System (INIS)

    Meurs, A.P.H. van; Seck, A.

    1997-01-01

    It would be logical to assume that many governments in the world would have more favorable fiscal terms for gas than for oil in order to stimulate gas development. The economics of gas is often less attractive than oil. In many countries gas markets are limited, often causing delays in gas development or restricting the level of production. Expensive gas pipeline and distribution systems need to be installed in order to deliver gas from the fields to markets. Prices for gas at the wellhead are usually lower than for oil on an energy equivalent basis. Gas is a desirable fuel for environmental reasons. Domestic gas development could result in a lower level of oil imports or increased oil exports. Low cost gas could be used in many ways to stimulate the development of certain industries. Finally, improved terms for gas could result in better overall petroleum exploration economics which often results in the discovery of more oil as well as gas. However, a comparative analysis of the government take for oil and for gas for the same concessions and contracts indicates that most governments still require identical fiscal terms for gas and oil. Only a few governments are stimulating gas development with more attractive fiscal terms

    General approaches to solving the problems of long-term planning of the construction-mounting work volume and introduction of power capacities at different paces of power unit commission and norms of construction time are considered. Problems associated with location and development of subsidiary industries providing NPP construction are discussed. It is shown that decrease of WWER-1000 reactor type NPP construction time from 24 to 12 months results in reduction of required high-skilled engineers, managerial staff, unique construction mechanisms and engines as well as in improvement of conditions for conducting measures on work arrangement during preparation of construction industry and mounting of the first assemblies

    2014-03-01

    Human memory is imperfect; thus, periodic review is required for the long-term preservation of knowledge and skills. However, students at every educational level are challenged by an ever-growing amount of material to review and an ongoing imperative to master new material. We developed a method for efficient, systematic, personalized review that combines statistical techniques for inferring individual differences with a psychological theory of memory. The method was integrated into a semester-long middle-school foreign-language course via retrieval-practice software. Using a cumulative exam administered after the semester's end, we compared time-matched review strategies and found that personalized review yielded a 16.5% boost in course retention over current educational practice (massed study) and a 10.0% improvement over a one-size-fits-all strategy for spaced study.

    worrying about Dutch Disease and, rather, welcome a higher Canadian dollar. But more than that, they should design policies that are better tailored for an economy that relies so heavily on imported intermediate inputs. Policy efforts would be far better put to eliminating tariffs and other trade barriers that make imported inputs more expensive, and thus hamper Canadian competitiveness. Policies should also focus on improving productivity, by inviting foreign investment, rather than subtly discouraging it through vehicles such as the Investment Canada Act. And certainly, anything that forces businesses to “buy local,” as Ontario’s Green Energy Act requires, will only stand in the way of Canadian businesses taking advantage of our higher dollar by importing lower-cost inputs from abroad. If policy-makers want to help Canadian factories, they shouldn’t complain about Alberta but instead focus on improving their domestic economic policies instead.

    Brainwave entrainment using rhythmic visual and/or auditory stimulation has shown its efficacy in modulating neural activities and cognitive ability. In the presented study, we aim to investigate whether rhythmic haptic stimulation could enhance short-term attention. An experiment with sensorimotor rhythm (SMR) increasing protocol was performed in which participants were presented sinusoidal vibrotactile stimulus of 15 Hz on their palm. Test of Variables of Attention (T.O.V.A.) was performed before and after the stimulating session. Electroencephalograph (EEG) was recorded across the stimulating session and the two attention test sessions. SMR band power manifested a significant increase after stimulation. Results of T.O.V.A. tests indicated an improvement in the attention of participants who had received the stimulation compared to the control group who had not received the stimulation. The D prime score of T.O.V.A. reveals that participants performed better in perceptual sensitivity and sustaining attention level compared to their baseline performance before the stimulating session. These findings highlight the potential value of using haptics-based brainwave entrainment for cognitive training.

  4. Body appreciation, sexual relationship status, and protective sexual behaviors in women.

    Winter, Virginia Ramseyer; Satinsky, Sonya

    2014-01-01

    The relationship between body appreciation and sexual risk reduction behavior in women is under-explored. This cross-sectional study examined the relationships between body appreciation, male condom use, and sexually transmitted infection (STI) testing among a community-based sample of women (n=285). Logistic regression results revealed that after controlling for age, BMI, and sexual orientation, having more than one sexual partner moderated body appreciation and current male condom use (OR=4.21, p<.01, CI=1.510-11.726). Body appreciation was not a significant predictor of STI testing in the previous 12 months. This suggests that women with higher body appreciation may be more likely to engage in some protective sexual health behaviors. Interventions that seek to improve body appreciation instead of body size change such as weight loss or gain may encourage certain protective sexual behaviors in women. Copyright © 2013 Elsevier Ltd.

  5. ComfortPower - System improvements and long-term evaluation

    Energy Technology Data Exchange (ETDEWEB)

    Silversand, Fredrik [Catator AB, Lund (Sweden)

    2011-11-15

    Catator has previously developed a novel heating system abbreviated ComfortPower in a RandD-programme supported by Catator, Swedish Gas Centre (SGC), Swedish Defence Materiel Administration (FMV), Skanska, Nibe and Alfa Laval. The ComfortPower unit comprises a multi fuel reformer system tied to a high-temperature polymer electrolyte fuel cell (HT-PEM) and a heat pump system. Since the residual heat from the fuel cell system can be utilized in a very effective way, it is possible to reach high thermal efficiencies. Indeed, the thermal efficiency in the unit has previously been shown to reach values as high as 175 - 200 % based on the lower heating value of the fuel. In addition to heat, ComfortPower can supply comfort cooling and surplus electricity. This project phase has focused on the following elements: 1. System improvements to further enhance the efficiency with existing fuel cell (HT-PEM). 2. System simplifications (e.g. DC-compressor system) to manage issues with start-up currents. 3. Tests with biogas qualities (various levels of CO{sub 2}) and biogas/air. 4. Long-term test with biogas quality (upgraded biogas). 5. Additional tests with liquid fuels (alcohols and diesel). 6. Map the need for cooling and heating in various applications. 7. Investigate how ComfortPower can reduce the primary energy consumption and reduce the environmental impact. 8. Study the possibility with a SOFC-based system with internal reforming. It was found that the Optiformer technology can be used to derive a suitable reformate gas for the HT-PEM unit from a wide range of fuels. Even if operation with fuel gases is the natural choice in most cases, it is possible also to use alcohols and other liquid fuels (e.g. in Campus applications). The heat pump system was equipped with a 24 V DC-compressor provided by Nibe. The compressor could be directly powered by the accumulator system and start-up currents, harmful to the inverter, could be avoided. Some improvements were made on the

  7. Gratitude and well being: the benefits of appreciation.

    Science.gov (United States)

    Sansone, Randy A; Sansone, Lori A

    2010-11-01

    The word "gratitude" has a number of different meanings, depending on the context. However, a practical clinical definition is as follows-gratitude is the appreciation of what is valuable and meaningful to oneself; it is a general state of thankfulness and/or appreciation. The majority of empirical studies indicate that there is an association between gratitude and a sense of overall well being. However, there are several studies that indicate potential nuances in the relationship between gratitude and well being as well as studies with negative findings. In terms of assessing gratitude, numerous assessment measures are available. From a clinical perspective, there are suggested therapeutic exercises and techniques to enhance gratitude, and they appear relatively simple and easy to integrate into psychotherapy practice. However, the therapeutic efficacy of these techniques remains largely unknown. Only future research will clarify the many questions around assessment, potential benefits, and enhancement of gratitude.

    the causes of its temporal and spatial variation has led to the appreciation of the impact of He I 1.083 micron emission from the earth's atmosphere. This adds a significant and variable background to the two filters and two grisms which include this spectral feature when the HST spacecraft is outside of the earth's shadow. After nearly five years in orbit, long term trending of the scientific and engineering behavior of WFC3 demonstrates excellent stability other than the expected decline in CCD charge transfer efficiency. Addition of post-flash signal to images is shown to markedly improve the transfer efficiency for low level signals. Combined with a pixel based correction algorithm developed at STScl, CCD performance is stabilized at levels only slightly degraded from its initial values.

    There is a significant gap in research regarding the readability and comprehension of existing sexual function measures. Patient-reported outcome measures may use terms not well understood by respondents with low literacy. This study aims to test comprehension of words and phrases typically used in sexual function measures to improve validity for all individuals, including those with low literacy. We recruited 20 men and 28 women for cognitive interviews on version 2.0 of the Patient-Reported Outcome Measurement Information System(®) (PROMIS(®) ) Sexual Function and Satisfaction measures. We assessed participants' reading level using the word reading subtest of the Wide Range Achievement Test. Sixteen participants were classified as having low literacy. In the first round of cognitive interviews, each survey item was reviewed by five or more people, at least two of whom had lower than a ninth-grade reading level (low literacy). Patient feedback was incorporated into a revised version of the items. In the second round of interviews, an additional three or more people (at least one with low literacy) reviewed each revised item. Participants with low literacy had difficulty comprehending terms such as aroused, orgasm, erection, ejaculation, incontinence, and vaginal penetration. Women across a range of literacy levels had difficulty with clinical terms like labia and clitoris. We modified unclear terms to include parenthetical descriptors or slang equivalents, which generally improved comprehension. Common words and phrases used across measures of self-reported sexual function are not universally understood. Researchers should appreciate these misunderstandings as a potential source of error in studies using self-reported measures of sexual function. This study also provides evidence for the importance of including individuals with low literacy in cognitive pretesting during the measure development. © 2014 International Society for Sexual Medicine.

  15. Aesthetic Engagement, Ecosophy C, and Ecological Appreciation

    Directory of Open Access Journals (Sweden)

    Cheng Xiangzhan

    2013-01-01

    Full Text Available With the aim of healing the earth and sustain a healthy ecosystem for all life forms, not humankind alone, ecoaesthetics emerges as a critique of Enlightenment mentality and of modern aesthetics as it is embodied in it. This mentality contributes greatly to the global ecological crisis and to other problem areas, such as population, economic, political and religious ones. In my understanding of aesthetics, ecoaesthetics is defined as the theory of ecological aesthetic appreciation.[1] With ecoaesthetics as my research horizon, there are at least two reasons for me to pay special attention to American philosopher Arnold Berleant’s conception of aesthetic engagement and his aesthetic theory based on it, an aesthetics of engagement. The first is our shared theme, which is the critique of modern aesthetics. The second reason is more complex for it involves the crucial question of the proper manner of aesthetic appreciation. From the perspective of ecoaesthetics, the contemplation of objects by a separated perceiver, an approach that is based on the modern philosophical dualism of subject and object, is unsatisfactory and inadequate. Berleant’s aesthetic engagement is a more satisfactory account of appreciation that is aesthetic and ecological. This emphasizes the ecological continuity or interrelatedness between the human appreciator and objects. Of course, any theory can occasion critique and development. Based on Berleant’s idea of aesthetic engagement, I would like to propose Ecosophy C. This can be contrasted with Ecosophy T proposed by the Norwegian, Arne Naess, and with traditional Chinese aesthetic wisdom. In contrast with these, I would like to develop my own view of ecological understanding. In order to construct a more comprehensive and reasonable ecoaesthetics, my Ecosophy C contains eight points that are crucial in building an ecological model of aesthetic appreciation for this period of ecological crisis.

  16. Improvement of Emergency Cooldown Tank in terms of long-term cooling

    SMART received its Standard Design Approval(SDA) from Korea Government in 2012. After Fukushima accident, passively cooling system of nuclear reactor gets great attention and a consentience reached that at least 72 hours of grace time after an accident should be secured, during which a nuclear reactor remains in safe condition without any operator's intervention. To meet this requirement, SMART adapted passive cooling system such as passive residual heat removal system(PRHRS). It is composed of an emergency cooldown tank(ETC), a heat exchanger and a makeup tank. The ETC should be refilled periodically by auxiliary water supply system in order to use it beyond 72 hours. Otherwise the immersed heat exchanger would be exposed to the air, which would damage the function of PRHRS. To overcome this shortcoming, installation of an air-cooling heat exchanger at the top of the ETC is proposed as shown in Fig. 2. Here the top of the ETC is now closed. Evaporated steam is collected through the vertical duct and condensed through air-cooling heat exchanger. By natural circulation, water level of ETC can be maintained at steady state for a very long-term period. The purpose of the present study is to investigate the thermal sizing of air-cooling heat exchanger which extends the cooling period of ETC. Thermal sizing of air-cooling heat exchanger had been investigated by using several heat transfer correlations for natural convection of vertical tubes. Quantitative comparisons were made to find out how many tubes are required to remove the residual heat. This work would contribute to improve the current design of ETC and to extend the cooling period much longer than 72 hours, which will promote the passive safety function of SMART

    Full Text Available Transiting planet discoveries have largely been restricted to the short-period or low-periastron distance regimes due to the bias inherent in the geometric transit probability. Through the refinement of planetary orbital parameters, and hence reducing the size of transit windows, long-period planets become feasible targets for photometric follow-up. Here we describe the TERMS project that is monitoring these host stars at predicted transit times.

  18. Body appreciation and attitudes toward menstruation.

    2015-01-01

    Menstruation is an important function of the female body, yet it has rarely been included in research on body image. As women's attitudes toward menstruation are so often negative, this study was designed to examine whether women with positive body image would have more positive attitudes toward menstruation. Seventy-two American women, ages 18-45 years, were recruited online to complete the Body Appreciation Scale (Avalos et al., 2005) and the Beliefs about and Attitudes toward Menstruation Scale (Marván et al., 2006) and to answer some questions about their interest in menstrual suppression. Linear regressions showed that higher scores on body appreciation predicted more positive attitudes toward and beliefs about menstruation, but were not related to interest in menstrual suppression. Our findings may be useful in designing interventions to increase women's comfort with their bodies and bodily functions. Copyright © 2014 Elsevier Ltd. All rights reserved.

  19. THE PRACTICAL ASPECT OF DEVELOPING ART APPRECIATION

    Full Text Available In the present article the significance and the role of art appreciation are dealt with. The ways and procedures of developing art appreciation of pupils in primary school are presented. With the support of the procedure of gradual uncovering of an artwork, in which two different methods were employed, namely increasing the sharpness and fragmentary image, the response and experience of 14 – 15 years old pupils were investigated in this study. In this, focus was on the examination of appropriateness of the procedures according to the type of the selected artworks. The procedures were examined on two sets, namely on a set of artworks with realistically depicted motifs and on a set of abstract paintings. We have found the selected procedures were to a certain extent more appropriate for dealing with realistic motifs, and to a lesser extent for abstract motifs. For pupils it is more difficult to accept an unknown, alien image, they much more easily identify themselves with recognisable forms and motifs. The latter motivate and inspire them more; they activate communication and in consequence raise the level of the development of art appreciation.

    Immune responses to brain antigens after stroke contribute to poor outcome. We hypothesized that splenectomy would lessen the development of such responses and improve outcome. Male Lewis rats (275-350 g) underwent 2-hour middle cerebral artery occlusion immediately after splenectomy or sham splenectomy. Animals were survived to 4 weeks (672 hrs), and immune responses to myelin basic protein determined at euthanasia. Infarct volume was determined in a subset of animals euthanized at 72 hours. Behavioral outcomes were assessed to 672 hours. Splenectomy was associated with worse neurological scores early after stroke, but infarct size at 72 hours was similar in both groups. Behavioral outcomes and immune responses to myelin basic protein were also similar among splenectomized and sham-operated animals 672 hours after middle cerebral artery occlusion. Splenectomy did not alter the immune responses to brain antigens or improve outcome after stroke. Differences between this study and other studies of splenectomy and stroke are examined. © 2017 American Heart Association, Inc.

    Richard T. Cox's contributions to the foundations of probability theory and inductive logic are not generally appreciated or understood. This paper reviews his life and accomplishments, especially those in his book The Algebra of Probable Inference and his final publication Inference and Inquiry which, in this author's opinion, has the potential to influence in a significant way the design and analysis of self organizing systems which learn from experience. A simple application to the simulation of a neuron is presented as an example of the power of Cox's contribution.

  5. Long-Term Heating to Improve Receiver Performance

    Energy Technology Data Exchange (ETDEWEB)

    Glatzmaier, Greg C.; Cable, Robert; Newmarker, Marc

    2017-06-27

    The buildup of hydrogen in the heat transfer fluid (HTF) that circulates through components of parabolic trough power plants decreases receiver thermal efficiency, and ultimately, it decreases plant performance and electricity output. The generation and occurrence of hydrogen in the HTF provides the driving force for hydrogen to permeate from the HTF through the absorber tube wall and into the receiver annulus. Getters adsorb hydrogen from the annulus volume until they saturate and are no longer able to maintain low hydrogen pressure. The increase in hydrogen pressure within the annulus significantly degrades thermal performance of the receiver and decreases overall power-plant efficiency. NREL and Acciona Energy North America (Acciona) are developing a method to control the levels of dissolved hydrogen in the circulating HTF. The basic approach is to remove hydrogen from the expansion tanks of the HTF subsystem at a rate that maintains hydrogen in the circulating HTF to a target level. Full-plant steady-state models developed by the National Renewable Energy Laboratory (NREL) predict that if hydrogen is removed from the HTF within the expansion tanks, the HTF that circulates through the collector field remains essentially free of hydrogen until the HTF returns to the power block in the hot headers. One of the key findings of our modeling is the prediction that hydrogen will reverse-permeate out of the receiver annulus if dissolved hydrogen in the HTF is kept sufficiently low. To test this prediction, we performed extended heating of an in-service receiver that initially had high levels of hydrogen in its annulus. The heating was performed using NREL's receiver test stand. Results of our testing showed that receiver heat loss steadily decreased with daily heating, resulting in a corresponding improvement in receiver thermal efficiency.

  6. Priming semantic concepts affects the dynamics of aesthetic appreciation.

    Aesthetic appreciation (AA) plays an important role for purchase decisions, for the appreciation of art and even for the selection of potential mates. It is known that AA is highly reliable in single assessments, but over longer periods of time dynamic changes of AA may occur. We measured AA as a construct derived from the literature through attractiveness, arousal, interestingness, valence, boredom and innovativeness. By means of the semantic network theory we investigated how the priming of AA-relevant semantic concepts impacts the dynamics of AA of unfamiliar product designs (car interiors) that are known to be susceptible to triggering such effects. When participants were primed for innovativeness, strong dynamics were observed, especially when the priming involved additional AA-relevant dimensions. This underlines the relevance of priming of specific semantic networks not only for the cognitive processing of visual material in terms of selective perception or specific representation, but also for the affective-cognitive processing in terms of the dynamics of aesthetic processing.

  8. Aesthetic Appreciation, Ethics, and 9/11

    Directory of Open Access Journals (Sweden)

    Emmanouil Aretoulakis

    2008-01-01

    Full Text Available There have been numerous critical articles on what really happened on the otherwise beautiful morning of 11 September 2001. Beyond doubt, the bulk of the critical responses to the terrorist attacks focused on the ethical and humanitarian, or rather the unethical and inhumane implications of the atrocious act, leaving no room for any philosophical reflection on the potential assessment or reception of the event from the perspective of art and aesthetics. The few years that have gone by since 2001 have provided us with some a sense of emotional detachment from the horror of that day, a detachment that may have awakened our aesthetic and artistic instincts with regard to the attacks themselves as well as their visual representation. Chronological distance renders an unprejudiced and independent stance more possible now than ever. It also allows us to reconsider our initial politically correct and ethically justified repulsion of the efforts made by a few artists to aestheticize 9/11. Such repulsion, however, was associated with the delusion that by denouncing aesthetics we were really securing the prevalence of politics, morality and ethical responsibility in a terror-afflicted society. My point in this paper is that there is a need for aesthetic appreciation when contemplating a violent event such as the 9/11 terrorist attacks. What is more, appreciation of the beautiful, even in case of a 9/11, seems necessary because it is a key to establishing an ethical stance towards terror, life, and art. It should be stressed that independent aesthetic experience is not important in itself but is a means of cultivating an authentic moral and ethical judgment.

    2015-12-01

    Full Text Available This article provides a brief overview of Appreciative Organizing (AO, a term coined by the author in her graduate work to describe the roles that dialogue, listening, storytelling, community networks, social bonding, and leadership play in designing and leading meaningful community engagement initiatives that result in transformative partnerships. It offers constructive steps and a real-life example of how AO was used to strengthen relationships between an institution of higher learning and the community it serves. AO posits that in order to strengthen America’s sense of community, public engagement practices must become more inclusive and innovative, and better networked. It illustrates how this community-centered method, grounded in the philosophical principles of partnership, appreciation, hope, and imagination, transformed an administration and built a culture of continuous engagement that helped the college meet and exceed its institutional goals. Further, through this example, the article’s larger objective is to share ways in which this method, when broadly applied, can be used to build trust and strengthen working relationships within a community setting.

    Objectification theory posits internalization of an observer's gaze may negatively impact women's feelings about their bodies, which may subsequently affect their sexual function. Subjective body image and body size (i.e., body mass index [BMI]) have mixed relationships to women's sexuality, but assessment of positive body image as a sign of resistance to objectification has not been researched. This study explored relations between body appreciation and sexual function in women and assessed whether body size impacted this relationship. Cross-sectional data were collected online from 247 women, ages 18 to 58. Body appreciation scores were modestly negatively correlated with BMI, while BMI was not related to sexual function scores. After controlling for sexual orientation, partner status, and age, body appreciation predicted the arousal, orgasm, and satisfaction aspects of sexual function. Practitioners' encouragement of body appreciation may improve sexual function in a way that encouraging a reduction in body size may not. Copyright © 2011 Elsevier Ltd. All rights reserved.

    To report on an appreciation of caring presence practised by nurses in South Africa in order to facilitate an appreciative discourse in nursing and a return to caring values and attitudes. Appreciative reports on caring presence are often overlooked. Media may provide a platform for facilitating appreciation for caring presence practised by nurses. Such an appreciation may foster further practice of caring presence and re-ignite a caring ethos in nursing. This article provides an appreciative discourse on caring presence in nursing in the form of examples of caring presence practised by nurses. An anecdotal approach was followed. Social media, namely narratives on caring presence shared by nurses on a Facebook page, and formal media, namely news reports in which nurses are appreciated for their efforts, were used. Deductive content analysis was applied to analyse the narratives and news reports in relation to a definition of caring presence and types of caring presence. The analysis of the narratives and news reports resulted in an appreciative discourse in which examples of nurses practising caring presence could be provided. Examples of nurses practising caring presence could be found, and an appreciative discourse could be initiated. Appreciation ignites positive action and ownership of high-quality health care. Leadership should thus cultivate a culture of appreciating nurses, through using media, and encourage nurses to share how caring presence impact on quality in health care. © 2016 International Council of Nurses.

  15. Smell and Anosmia in the Aesthetic Appreciation of Gardens

    Directory of Open Access Journals (Sweden)

    Marta Tafalla

    2014-01-01

    Full Text Available In his Critique of the Power of Judgment, Kant defined the garden as a visual art and considered that smell plays no role in its aesthetic appreciation. If the Kantian thesis were right, then a person who has no sense of smell (who suffers from anosmia would not be impaired in his or her aesthetic appreciation of gardens. At the same time, a visually impaired person could not appreciate the beauty of gardens, although he or she could perceive them through hearing, smell, taste, and touch. In this paper I discuss the role of smell and anosmia in the aesthetic appreciation of gardens. I accept the Kantian idea that the appreciation of a garden is the appreciation of its form, but I also defend that, at least in some cases, smell can belong to the form of gardens and, consequently, the ability or inability to smell influences their aesthetic appreciation.

    All the authors are agreed on the need for a certain publicizing of health statistics, but do Amaral Pyrrait points out that the medical profession prefers to convince itself rather than to be convinced. While there is great utility in articles and reviews in the professional press (especially for paramedical personnel) Aubenque, de Groot, and Kohn show how appreciation can effectively be secured by making statistics more easily understandable to the non-expert by, for instance, including readable commentaries in official publications, simplifying charts and tables, and preparing simple manuals on statistical methods. Aubenque and Kohn also stress the importance of linking health statistics to other economic and social information. Benjamin suggests that the principles of market research could to advantage be applied to health statistics to determine the precise needs of the "consumers". At the same time, Aubenque points out that the value of the ultimate results must be clear to those who provide the data; for this, Kohn suggests that the enumerators must know exactly what is wanted and why.There is general agreement that some explanation of statistical methods and their uses should be given in the curricula of medical schools and that lectures and postgraduate courses should be arranged for practising physicians.

    Humor is a unique ability in human beings. Suls [A two-stage model for the appreciation of jokes and cartoons. In P. E. Goldstein & J. H. McGhee (Eds.), The psychology of humour. Theoretical perspectives and empirical issues. New York: Academic Press, 1972, pp. 81-100] proposed a two-stage model of humor: detection and resolution of incongruity. Incongruity is generated when a prediction is not confirmed in the final part of a story. To comprehend humor, it is necessary to revisit the story, transforming an incongruous situation into a funny, congruous one. Patient and neuroimaging studies carried out until now lead to different outcomes. In particular, patient studies found that right brain-lesion patients have difficulties in humor comprehension, whereas neuroimaging studies suggested a major involvement of the left hemisphere in both humor detection and comprehension. To prevent activation of the left hemisphere due to language processing, we devised a nonverbal task comprising cartoon pairs. Our findings demonstrate activation of both the left and the right hemispheres when comparing funny versus nonfunny cartoons. In particular, we found activation of the right inferior frontal gyrus (BA 47), the left superior temporal gyrus (BA 38), the left middle temporal gyrus (BA 21), and the left cerebellum. These areas were also activated in a nonverbal task exploring attribution of intention [Brunet, E., Sarfati, Y., Hardy-Bayle, M. C., & Decety, J. A PET investigation of the attribution of intentions with a nonverbal task. Neuroimage, 11, 157-166, 2000]. We hypothesize that the resolution of incongruity might occur through a process of intention attribution. We also asked subjects to rate the funniness of each cartoon pair. A parametric analysis showed that the left amygdala was activated in relation to subjective amusement. We hypothesize that the amygdala plays a key role in giving humor an emotional dimension.

    Helping students appreciate physics education is a formidable task, considering that many students struggle to pass introductory physics courses. Numerous efforts have been made for this undertaking because it is an important step leading to successful learning. In an out-of-classroom academic program, the Supplemental Instruction (SI) Program, we have used the approach, INSPIRE (inquiry, network, skillfulness, perseverance, intuition, reasoning, and effort), to help more students value their experiences in these courses. The method basically includes key elements outlined by experts in physics education [1]. Student responses have been encouraging. Having undergraduates as facilitators in the program is advantageous in promoting principles of physics education. Their training emphasizes tenacity, resourcefulness, understanding, support, and teamwork, i.e. TRUST. We present the organization and focus of the SI Program, and discuss how these improve learning atmosphere and facilitate learning. [1] Edward F. Redish et al, Am J. Phys. 66(3), March 1998.

  20. Modeling and mining term association for improving biomedical information retrieval performance.

    Science.gov (United States)

    Hu, Qinmin; Huang, Jimmy Xiangji; Hu, Xiaohua

    2012-06-11

    The growth of the biomedical information requires most information retrieval systems to provide short and specific answers in response to complex user queries. Semantic information in the form of free text that is structured in a way makes it straightforward for humans to read but more difficult for computers to interpret automatically and search efficiently. One of the reasons is that most traditional information retrieval models assume terms are conditionally independent given a document/passage. Therefore, we are motivated to consider term associations within different contexts to help the models understand semantic information and use it for improving biomedical information retrieval performance. We propose a term association approach to discover term associations among the keywords from a query. The experiments are conducted on the TREC 2004-2007 Genomics data sets and the TREC 2004 HARD data set. The proposed approach is promising and achieves superiority over the baselines and the GSP results. The parameter settings and different indices are investigated that the sentence-based index produces the best results in terms of the document-level, the word-based index for the best results in terms of the passage-level and the paragraph-based index for the best results in terms of the passage2-level. Furthermore, the best term association results always come from the best baseline. The tuning number k in the proposed recursive re-ranking algorithm is discussed and locally optimized to be 10. First, modelling term association for improving biomedical information retrieval using factor analysis, is one of the major contributions in our work. Second, the experiments confirm that term association considering co-occurrence and dependency among the keywords can produce better results than the baselines treating the keywords independently. Third, the baselines are re-ranked according to the importance and reliance of latent factors behind term associations. These latent

    Surface finishing methods, such as Water Jet Peening (WJP), have been applied to welds in some major components of nuclear power plants as a counter measure to Primary Water Stress Corrosion Cracking (PWSCC). In addition, the methods of surface finishing (buffing treatment) is being standardized, and thus the buffing treatment has been also recognized as the well-established method of improving stress. On the other hand, the long-term stability of peening techniques has been confirmed by accelerated test. However, the effectiveness of stress improvement by surface treatment is limited to thin layers and the effect of complicated residual stress distribution in the weld metal beneath the surface is not strictly taken into account for long-term stability. This paper, therefore, describes the accelerated tests, which confirmed that the long-term stability of the layer subjected to buffing treatment was equal to that subjected to WJP. The long-term reliability of very thin stress improved layer was also confirmed through a trial evaluation by thermal elastic-plastic creep analysis, even if the effect of complicated residual stress distribution in the weld metal was excessively taken into account. Considering the above findings, an approach is proposed for constructing the prediction method of the long-term reliability of stress improvement by surface finishing. (author)

  2. Benefit of infrared images in visibility appreciation for fog conditions

    Boucher, V.; Dumoulin, J.; Marchetti, M.

    2012-04-01

    Fog situations induce an increase in both accident probability and severity. They constitue a significant part in accident rate. There is very few means to forecast fog, nor to appreciate its density, and its associated visibility decrease. An approach consists in developing on-board tools to qualify and to quantify the fog, and to improve the visibility within each vehicle. Infrared technology is now more common, so solutions based on this specific spectral band could be considered. LW infrared has demonstrated its value in the case of passenger cars. Its use could be discussed too, in particular in the case of obstacles detection. The study presented here deals mainly with the extraction of a visbility distance from LW thermal images in the presence of fog. A French facility in Clermont-Ferrand allows the generation of fog. It can be generated in day or night conditions. The facility is 30 m long, for a 220 m3 volume. The fog is generated spraying water micro droplets, which size is controlled and measured. Experimental conditions could be adapted through water pressure, water nature as an example. Visibility is appreciated with a device measuring light transmission. In the case of infrared, visibility is obtained through the definition of contrast of an object on a given background. On such a basis, infrared spectral band provides a factor 2 benefit on a conventional roadsign, and of a factor 4 in the case of a heated one, with meteorological visibilty of 20 m. Some theoritical aspects will be described, along with a description of the whole experimental setup.

  3. Developing compassion through a relationship centred appreciative leadership programme.

    2014-09-01

    Recent attention in health care focuses on how to develop effective leaders for the future. Effective leadership is embodied in relationships and should be developed in and with staff and patients. This paper describes development, implementation and evaluation of an appreciative and relationship centred leadership programme carried out with 86 nursing staff covering 24 in-patient areas within one acute NHS Board in Scotland. The aim of the programme was to support staff to work together to develop a culture of inquiry that would enhance delivery of compassionate care. The 12 month Leadership Programme used the principles of appreciative relationship centred leadership. Within this framework participants were supported to explore relationships with self, patients and families, and with teams and the wider organisation using caring conversations. Participants worked within communities of practice and action learning sets. They were supported to use a range of structured tools to learn about the experience of others and to identify caring practices that worked well and then explore ways in which these could happen more of the time. A range of methods were used to evaluate impact of the programme including a culture questionnaire and semi structured interviews. Immersion crystallisation technique and descriptive statistics were used to analyse the data. Key themes included; enhanced self-awareness, better relationships, greater ability to reflect on practice, different conversations in the workplace that were more compassionate and respectful, and an ethos of continuing learning and improvement. The programme supported participants to think in different ways and to be reflective and engaged participants rather than passive actors in shaping the cultural climate in which compassionate relationship centred care can flourish. Multidisciplinary programmes where the process and outcomes are explicitly linked to organisational objectives need to be considered in future

    Appreciation is a key component of subjective well-being and may contribute to positive mental health. Few studies have examined relationships between specific aspects of appreciation and the 3 dimensions of positive mental health, and thus, the aim of this study was to identify associations between aspects of appreciation and positive mental health. Appreciation and positive mental health were measured in 266 Korean university students (50% females) using the Appreciation Inventory and the Mental Health Continuum-Short Form. The results obtained showed that Have Focus significantly predicted Emotional Well-being; Have Focus and Loss/Adversity significantly predicted Social Well-being and Have Focus, Expression and Nature/Daily Life significantly predicted Psychological Well-being. The implications of results that might enable positive mental health to be enhanced are discussed. © 2015 International Union of Psychological Science.

    Full Text Available In this paper, we present a two-part study. The first part was a cultural appreciation study. Through this study, we explored the specific approach of cross-cultural aesthetic appreciation and mapped out the potential insights for a prototype design. In the second part, we carried out a design-led study. We designed a tablet application and conducted focus group studies to explore the interactive technology that assists in the support of cross-cultural audiences’ aesthetic appreciation and engagement of traditional Chinese painting. Based on these findings, we went on to further explore an approach of interactive engagement which is specific to supporting cross-cultural appreciation, while also reflecting upon the interactive design suggestions for the development of aesthetic appreciation to offer various transferable insights to the Human–Computer Interaction (HCI community.

    Homan, Kristin J; Tylka, Tracy L

    2018-06-01

    Although researchers and clinicians recognize the importance of positive body image for women's well-being, development of theoretical frameworks for understanding positive body image has not kept pace with research documenting its many benefits. The present study proposed and tested a comprehensive model linking gratitude, contingent self-worth, social comparison, body appreciation, and intuitive eating. Path analysis indicated that this model fit the data for a sample of college and online community women (N = 263). Gratitude was indirectly linked to body appreciation via lower investment in self-worth based on appearance and others' approval, and via lower engagement in eating and body comparison. Gratitude had a strong direct effect on body appreciation, and body appreciation accounted for a large portion (88%) of gratitude's relationship with intuitive eating. These results provide strong preliminary support for the model, revealing that gratitude, which can be improved via intervention, plays a key role in body appreciation. Copyright © 2018 Elsevier Ltd.

  17. Difference in brain activations during appreciating paintings and photographic analogues

    Directory of Open Access Journals (Sweden)

    Yoshinori eMizokami

    2014-07-01

    Full Text Available Several studies have investigated neural correlates of aesthetic appreciation for paintings but to date the findings have been heterogeneous. This heterogeneity may be attributed to previous studies’ measurement of aesthetic appreciation of not only the beauty of paintings but also the beauty of motifs of the paintings. In order to better elucidate the beauty of paintings, it seems necessary to compare aesthetic appreciation of paintings and photographic analogues which included corresponding real images. We prepared for famous painters’ pictures and their photographic analogues which were set up to resemble each painting in order to investigate the hypothesis that there exist specific neural correlates associated with the aesthetic appreciation for paintings. Forty-four subjects participated in functional magnetic resonance study which required comparisons of aesthetic appreciation of paintings of still life and landscape versus photographic analogues including corresponding real images of still life and landscape. Bilateral cuneus and the left lingual gyrus were activated in the comparison of aesthetic appreciation of paintings versus photographic analogues. In conclusion, the present findings suggest a possibility of the existence of specific neural correlates associated with the aesthetic appreciation for paintings and that bilateral cuneus and the left lingual gyrus may be involved.

    Despite reduced perioperative mortality and routine use of adjuvant therapy following pancreatectomy for pancreatic ductal adenocarcinoma (PDAC), improvement in long-term outcome has been difficult to ascertain. This study compares outcomes in patients undergoing resection for PDAC within a single, high-volume academic institution over two sequential time periods. Retrospective review of patients with resected PDAC, in two cohorts: period 1 (P1), 1991-2000; and period 2 (P2), 2001-2010. Univariate and multivariate analyses using the Cox proportional hazards model were performed to determine prognostic factors associated with long-term survival. Survival was evaluated using Kaplan-Meier analyses. A total of 179 pancreatectomies were performed during P1 and 310 during P2. Perioperative mortality was 6.7 % (12/179) in P1 and 1.6 % (5/310) in P2 (p = 0.003). P2 had a greater number of lymph nodes resected (17 [0-50] vs. 7 [0-31]; p P2 (p P2 (p < 0.001). Factors associated with improved long-term survival remain comparable over time. Short- and long-term survival for patients with resected PDAC has improved over time due to decreased perioperative mortality and increased use of adjuvant therapy, although the proportion of 5-year survivors remains small.

    2007-09-01

    In certain patients with left ventricular (LV) systolic dysfunction, improvements in cardiac function are seen after initiation of medical therapy; however, the long-term stability of ventricular function in such patients is not well described. We retrospectively analyzed 171 patients who had a baseline ejection fraction of 45% or less, a follow-up echocardiogram at 2 to 12 months after initiation of medical therapy, and a final echocardiogram. We found that 48.5% of the patients demonstrated initial improvements in LV function after initiation of medical therapy, and the improvements appear to be sustained (88% of patients) at 44 +/- 21 months follow-up. A nonischemic etiology and younger age were the only independent predictors of change of LV ejection fraction of 10 or more at a mean 8.4 +/- 3.4 months after optimal medical therapy. Our study revealed a trend toward improved long-term survival in individuals with an early improvement in LV ejection fraction with medical therapy, especially in those with sustained improvement.

    To describe how actions of nursing unit leaders influenced the long-term sustainability of a best practice guidelines (BPG) program on inpatient units. Several factors influence the initial implementation of evidence-based practice improvements in nursing, with leadership recognized as essential. However, there is limited knowledge about enduring change, including how frontline nursing leaders influence the sustainability of practice improvements over the long term. A qualitative descriptive case study included 39 in-depth interviews, observations, and document reviews. Four embedded nursing unit subcases had differing levels of program sustainability at 7 years (average) following implementation. Higher levels of BPG sustainability occurred on units where formal leadership teams used an integrated set of strategies and activities. Two key strategies were maintaining priorities and reinforcing expectations. The coordinated use of six activities (e.g., discussing, evaluating, integrating) promoted the continuation of BPG practices among staff. These leadership processes, fostering exchange and learning, contributed to sustainability-promoting environments characterized by teamwork and accountability. Unit leaders are required to strategically orchestrate several overlapping and synergistic efforts to achieve long-term sustainability of BPG-based practice improvements. As part of managing overall unit performance, unit leaders may influence practice improvement sustainability by aligning vision, strategies, and activities. © 2015 John Wiley & Sons Ltd.

    Background Gastroesophageal reflux disease (GERD) is a chronic symptomatic condition and may be associated with erosive esophagitis (EE). Considerable data on the long-term maintenance of healing of EE are available, but data on long-term GERD symptom prevention and patient quality of life (QOL) are limited. Aims To investigate QOL in subjects with healed EE who received 12 months of double-blind maintenance treatment with lansoprazole or ranitidine, followed by long-term open-label lansoprazole therapy to prevent recurrence of EE. Methods Subjects with healed EE received 12 months of double-blind maintenance treatment with lansoprazole 15 mg once daily or ranitidine 150 mg twice daily, followed by dose-titrated, open-label lansoprazole therapy for up to 82 months. Results During double-blind treatment (n = 206), lansoprazole-treated patients showed significantly (P ≤ 0.05) greater improvements than ranitidine-treated patients in the frequency, severity, and ‘bothersomeness’ of heartburn, the symptom index, problems of activity limitation, eating and drinking problems, symptom problems, health distress, and social functioning. During dose-titrated, open-label treatment (n = 195), all disease-specific QOL scales except sleep improved significantly (P lansoprazole for 12 months in healed EE subjects produced significantly greater improvements in QOL indicators than ranitidine. These improvements were sustained during dose-titrated, open-label lansoprazole treatment. PMID:19582579

    2013-01-01

    The purpose of this study was to measure the effect of action video gaming on central elements of visual attention using Bundesen's (1990) Theory of Visual Attention. To examine the cognitive impact of action video gaming, we tested basic functions of visual attention in 42 young male adults. Participants were divided into three groups depending on the amount of time spent playing action video games: non-players (15h/month, N=20). All participants were tested in three tasks which tap central functions of visual attention and short-term memory: a test based on the Theory of Visual Attention (TVA), an enumeration test and finally the Attentional Network Test (ANT). The results show that action video gaming does not seem to impact the capacity of visual short-term memory. However, playing action video games does seem to improve the encoding speed of visual information into visual short-term memory and the improvement does seem to depend on the time devoted to gaming. This suggests that intense action video gaming improves basic attentional functioning and that this improvement generalizes into other activities. The implications of these findings for cognitive rehabilitation training are discussed. Copyright © 2012 Elsevier B.V. All rights reserved.

    2015-06-01

    Full Text Available Melanie McGrice, Kathlene Don Paul Nutrition Plus Enterprises, Melbourne, VIC, Australia Abstract: Bariatric surgery aims to provide long-term weight loss and improvement in weight-related comorbidities. Unfortunately, some patients do not achieve predicted weight loss targets and many regain a portion of their lost weight within 2–10 years postsurgery. A review of the literature found that behavioral, dietary, psychological, physical, and medical considerations can all play a role in suboptimal long-term weight loss. Recommendations to optimize long-term weight loss include ensuring that the patient understands how the procedure works, preoperative and postoperative education sessions, tailored nutritional supplements, restraint with liquid kilojoules, pureed foods, grazing and eating out of the home, an average of 60 minutes of physical activity per day, and lifelong annual medical, psychological, and dietary assessments.Keywords: weight, bariatric, surgery

    Tylka, Tracy L; Wood-Barcalow, Nichole L

    2015-01-01

    Considered a positive body image measure, the 13-item Body Appreciation Scale (BAS; Avalos, Tylka, & Wood-Barcalow, 2005) assesses individuals' acceptance of, favorable opinions toward, and respect for their bodies. While the BAS has accrued psychometric support, we improved it by rewording certain BAS items (to eliminate sex-specific versions and body dissatisfaction-based language) and developing additional items based on positive body image research. In three studies, we examined the reworded, newly developed, and retained items to determine their psychometric properties among college and online community (Amazon Mechanical Turk) samples of 820 women and 767 men. After exploratory factor analysis, we retained 10 items (five original BAS items). Confirmatory factor analysis upheld the BAS-2's unidimensionality and invariance across sex and sample type. Its internal consistency, test-retest reliability, and construct (convergent, incremental, and discriminant) validity were supported. The BAS-2 is a psychometrically sound positive body image measure applicable for research and clinical settings. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Spam problem constantly increases its severity: currently about 90% of e-mails received daily by CERN Mail servers are unsolicited messages - called ‘Spam' - and spammers are doing their best to bypass anti-spam filters. In these conditions, users' feedback is priceless. It allows the CERN Mail Service to improve Spam fighting performance, and of course reduce the number of received unsolicited mails. Outlook users should note the existence of ‘anti-Spam buttons': ‘Check Spam classification of an e-mail', ‘Update personal whitelist' and ‘Report Spam'. The ‘Report Spam' button is very important: it removes the selected Spam from your Inbox, and sends a copy to the CERN Mail Service. Those reports are used to build new filters nearly in real time; a new Spam might be blocked in less than 15 minutes! Therefore, every Outlook user is warmly encouraged to get rid of the Spam messages received in the Inbox folder by using the ‘Report Spam' button and not b...

    The aim of the present study was to evaluate the effects of diphenyl diselenide (PhSe)2 supplemented diet (10ppm) associated to the administration of caffeine (15mg/kg; i.g.) for 30days on the novel object recognition memory in middle-aged rats. The present findings showed that (PhSe)2-supplemented diet enhanced short-term memory, but not long-term memory, of middle-aged rats in the novel object recognition task. The (PhSe)2 supplemented diet associated with caffeine administration improved long-term memory, but did not alter short-term memory, impaired in middle-aged rats. Daily caffeine administration to middle-aged rats had no effect on the memory tasks. Diet supplemented with (PhSe)2 plus caffeine administration increased the number of crossings and rearings reduced in middle-aged rats. Caffeine administration plus (PhSe)2 diets were effective in increasing the number of rearings and crossings, respectively, in middle-aged rats, [(3)H] glutamate uptake was reduced in hippocampal slices of rats from (PhSe)2 and caffeine plus (PhSe)2 groups. In addition, animals supplemented with (PhSe)2 showed an increase in the pCREB/CREB ratio whereas pAkt/Akt ratio was not modified. These results suggest that the effects of (PhSe)2 on the short-term memory may be related to its ability to decrease the uptake of glutamate, influencing the increase of CREB phosphorylation. (PhSe)2-supplemented diet associated to the administration of caffeine improved long-term memory impaired in middle-aged rats, an effect independent of CREB and Akt phosphorylation.

  14. Humor appreciation of captionless cartoons in obsessive-compulsive disorder

    Science.gov (United States)

    2011-01-01

    Background It seems that the core neural regions and cognitive processes implicated in obsessive-compulsive disorder (OCD) pathophysiology may overlap with those involved in humor appreciation. However, to date, there have been no studies that have explored humor appreciation in OCD. The purpose of the present work was to investigate humor appreciation in a group of patients with OCD. Methods We examined 25 patients with OCD and 25 healthy controls, matched by age, education, and gender. We administered Penn's Humor Appreciation Test (PHAT), a computerized test comprising captionless cartoons by Mordillo. Each set of stimuli consisted of two almost identical drawings, one of which was funny due to the alteration of a detail in the cartoon, whereas the other was not funny. Severity of psychopathology was evaluated with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). Results No significant effect for group, gender or group × gender interaction was found on the PHAT scores. In OCD patients, humor appreciation was not significantly associated with age of onset, duration of illness, and obsessions, but correlated significantly with compulsions. Conclusions Humor appreciation, based on captionless cartoons in OCD, does not seem to be deficient compared to healthy subjects but may be related to illness characteristics. PMID:22103926

  15. Short-Term City Electric Load Forecasting with Considering Temperature Effects: An Improved ARIMAX Model

    Directory of Open Access Journals (Sweden)

    Herui Cui

    2015-01-01

    Full Text Available Short-term electric load is significantly affected by weather, especially the temperature effects in summer. External factors can result in mutation structures in load data. Under the influence of the external temperature factors, city electric load cannot be easily forecasted as usual. This research analyzes the relationship between electricity load and daily temperature in city. An improved ARIMAX model is proposed in this paper to deal with the mutation data structures. It is found that information amount of the improved ARIMAX model is smaller than that of the classic method and its relative error is less than AR, ARMA and Sigmoid-Function ANN models. The forecasting results are more accurately fitted. This improved model is highly valuable when dealing with mutation data structure in the field of load forecasting. And it is also an effective technique in forecasting electric load with temperature effects.

  16. Perspectives for hydropower stations in Switzerland: long-term competitiveness and possibilities for improvement

    Filippini, M.; Banfi, S.; Luchsinger, C.; Wild, J.; Balmer, M.; Grand, D.; Henkels, L.; Semadeni, M.; Gnansounou, E.

    2001-01-01

    This first general study - which has the character of a preliminary study - examines the questions if the liberalisation of the electricity market will have a negative effect on the competitiveness of hydropower in the long-term and what measures can be taken against such effects. Long-term competitiveness is defined as the ability of a business in this sector to make investments in renewal in the long-term, i.e. after its concessions have expired. The three main aims of the study are: 1. Assessment of the long-term competitiveness of the sector and identification of the factors which could either have a negative effect on it or improve it, 2. Analysis of cost structures and presentation of measures through which the long-term competitiveness of the sector can be reinforced, 3. Presentation of possible political measures to be taken in this business area in order to improve the long-term competitiveness of hydropower stations. The study identifies the most important factors that determine future competitiveness as being the market prices for electricity and capital costs (depreciation and interest on own and borrowed capital). Further, water fees, taxes and regulations concerning residual water flow can be of great importance for investment decisions, in particular for those enterprises that operate close to their profitability limits. The results of the analysis indicate that, in the future, a considerable number of enterprises must be reckoned with that will refrain from renewing their plant. Such outcomes depend, of course, on developments in electricity market prices, specific investment costs, rates of interest and other economic, political, and legal conditions. Making a prognosis about the development of such parameters is linked with a high degree of uncertainty. By means of sensitivity calculations and the definition of various scenarios, attempts are made to take these uncertainties into account . Finally, the study makes reference to the fact that

    Patients with autism spectrum disorders (ASDs) exhibit core autistic symptoms including social impairments from early childhood and mostly show secondary disabilities such as irritability and aggressive behavior based on core symptoms. However, there are still no radical treatments of social impairments in these patients. Oxytocin has been reported to play important roles in multiple social behaviors dependent on social recognition, and has been expected as one of the effective treatments of social impairments of patients with ASDs. We present a case of a 16-year-old girl with autistic disorder who treated by long-term administration of oxytocin nasal spray. Her autistic symptoms were successfully treated by two month administration; the girl's social interactions and social communication began to improve without adverse effects. Her irritability and aggressive behavior also improved dramatically with marked decreases in aberrant behavior checklist scores from 69 to 7. This case is the first to illustrate long-term administration of oxytocin nasal spray in the targeted treatment of social impairments in a female with autistic disorder. This case suggests that long-term nasal oxytocin spray is promising and well-tolerated for treatment of social impairments of patients with ASDs.

    Previous work has shown that exposure to images of nature results in elevated state body appreciation, but static images may lack ecological validity. Here, we examined the impact of exposure to short films of simulated, first-person walks in natural or built environments. Thirty-six university students completed a measure of state body appreciation before and after watching films of either a walk in a natural or a built environment created specifically for the present study. Two weeks later, they completed the same task but watched the other film type. Results indicated that exposure to the film of a natural environment resulted in significantly elevated state body appreciation (d = 0.66). There was no significant change in state body appreciation following exposure to the film of the built environment (d = 0.14). These findings suggest that exposure to films depicting the natural environment may promote immediate, moderate-sized improvements in state body image. Copyright © 2018 Elsevier Ltd.

    Climatic, atmospheric, and land-use changes all have the potential to alter soil microbial activity via abiotic effects on soil or mediated by changes in plant inputs. Recently, many promising microbial models of soil organic carbon (SOC) decomposition have been proposed to advance understanding and prediction of climate and carbon (C) feedbacks. Most of these models, however, exhibit unrealistic oscillatory behavior and SOC insensitivity to long-term changes in C inputs. Here we diagnose the sources of instability in four models that span the range of complexity of these recent microbial models, by sequentially adding complexity to a simple model to include microbial physiology, a mineral sorption isotherm, and enzyme dynamics. We propose a formulation that introduces density-dependence of microbial turnover, which acts to limit population sizes and reduce oscillations. We compare these models to results from 24 long-term C-input field manipulations, including the Detritus Input and Removal Treatment (DIRT) experiments, to show that there are clear metrics that can be used to distinguish and validate the inherent dynamics of each model structure. We find that widely used first-order models and microbial models without density-dependence cannot readily capture the range of long-term responses observed across the DIRT experiments as a direct consequence of their model structures. The proposed formulation improves predictions of long-term C-input changes, and implies greater SOC storage associated with CO2-fertilization-driven increases in C inputs over the coming century compared to common microbial models. Finally, we discuss our findings in the context of improving microbial model behavior for inclusion in Earth System Models.

    This study examined juvenile justice-involved youths' understanding and appreciation of the Miranda warnings' rights to silence and legal counsel using the Miranda Rights Comprehension Instruments (Goldstein, Zelle, & Grisso, 2012). It also examined the relationships between totality of circumstances factors and understanding and appreciation of rights. Data were collected from 183 youths (140 boys) in pre- and postadjudication facilities in 2 states. Overall, youths demonstrated greater difficulty on measures of appreciation than understanding, with particular deficits in their abilities to comprehend the abstract concept of the right to silence. Results varied slightly by instrument, highlighting the importance of a multimodal assessment of these complex abilities. Examination of totality of circumstances factors identified relationships between some factors (e.g., age, verbal IQ, academic achievement) and Miranda comprehension, but revealed that other factors (e.g., gender, number of previous arrests) were not significantly related to Miranda understanding or appreciation. The findings support a nuanced conceptualization of Miranda rights comprehension that acknowledges the complexity of understanding and appreciating the warnings. Empirical analyses also support the continued use of some totality of circumstances factors and abandonment of others. Findings underscore the necessity of multimodal assessment and interpretation when conducting capacity to waive Miranda rights evaluations. (c) 2015 APA, all rights reserved).

    In recent years, the phase-space reconstruction method has usually been used for mid- and long-term runoff predictions. However, the traditional phase-space reconstruction method is still needs to be improved. Using the genetic algorithm to improve the phase-space reconstruction method, a new nonlinear model of monthly runoff is constructed. The new model does not rely heavily on embedding dimensions. Recognizing that the rainfall–runoff process is complex, affected by a number of factors, more variables (e.g. temperature and rainfall) are incorporated in the model. In order to detect the possible presence of chaos in the runoff dynamics, chaotic characteristics of the model are also analyzed, which shows the model can represent the nonlinear and chaotic characteristics of the runoff. The model is tested for its forecasting performance in four types of experiments using data from six hydrological stations on the Yellow River and the Yangtze River. Results show that the medium-and long-term runoff is satisfactorily forecasted at the hydrological stations. Not only is the forecasting trend accurate, but also the mean absolute percentage error is no more than 15%. Moreover, the forecast results of wet years and dry years are both good, which means that the improved model can overcome the traditional ‘‘wet years and dry years predictability barrier,’’ to some extent. The model forecasts for different regions are all good, showing the universality of the approach. Compared with selected conceptual and empirical methods, the model exhibits greater reliability and stability in the long-term runoff prediction. Our study provides a new thinking for research on the association between the monthly runoff and other hydrological factors, and also provides a new method for the prediction of the monthly runoff. - Highlights: • The improved phase-space reconstruction model of monthly runoff is established. • Two variables (temperature and rainfall) are incorporated

  5. Improving the long-term sustainability of health aid: are Global Health Partnerships leading the way?

    2010-09-01

    Over the last decade development assistance for health has more than doubled. This increase provides an unprecedented opportunity to scale up health services, and in doing so, achieve the health Millennium Development Goals. However, sustaining scaling up will in turn require sustainable donor support until domestic health financing can substitute for it. The provision of long-term predictable finance is of particular concern in health because the bulk of costs are recurrent and many interventions require sustained, multi-year support to be successful. This is also true for health systems strengthening efforts. As the bulk of new aid resources flow through Global Health Partnerships (GHPs), their ability to make long-term commitments is critical to health systems development. In order to better understand the constraints that prevent development partners from making long-term commitments of health aid, the World Health Organization reviewed the practices of seven major health partners in committing development assistance funds over the long term. The review found increasing evidence of long-term commitments of aid for health in each of the seven agencies. The GHPs and their funders have been at the forefront of this trend, pioneering many of the new approaches. The study concludes that all partners have scope to improve the duration of aid within existing rules and regulations, and that the main constraints to doing so are political. Predictability is even more of a concern in current global economic circumstances, as access to resources begins to be squeezed. In this context it is important that we learn from GHPs, which have successfully tested innovative approaches to both raising and disbursing health funds. The prospects for change associated with the new administration in the United States-the largest health donor and the most unpredictable, but also a major supporter of GHPs-make this task even more urgent.

    Full Text Available Myotonic dystrophy type 1, also known as Steinert′s disease, is an autosomal dominant disorder with multisystemic clinical features affecting the skeletal and cardiac muscles, the eyes, and the endocrine system. Thiamine (vitamin B1 is a cofactor of fundamental enzymes involved in the energetic cell metabolism; recent studies described its role in oxidative stress, protein processing, peroxisomal function, and gene expression. Thiamine deficiency is critical mainly in the central and peripheral nervous system, as well as in the muscular cells. Our aim was to investigate the potential therapeutical effects of long-term treatment with thiamine in myotonic dystrophy type 1 in an observational open-label pilot study. We described two patients with myotonic dystrophy type 1 treated with intramuscular thiamine 100 mg twice a week for 12 or 11 months. We evaluated the patients using the grading of muscle strength according to Medical Research Council (MRC, the Muscular Impairment Rating Scale (MIRS, and the Modified Barthel index. High-dose thiamine treatment was well tolerated and effective in improving the motor symptomatology, particularly the muscle strength evaluated with the MRC scale, and the patients′ activities of daily living using the Modified Barthel Index. At the end of treatment, the MRC score was 5 in the proximal muscles and 2-4 in the distal muscles (the MRC score before the treatment was 3-4 and 1-3, respectively. The MIRS grade improved by 25% compared to baseline for both patients. In patient #1, the Modified Barthel Index improved by 44%, and in patient #2 by 29%. These findings suggest that clinical outcomes are improved by long-term thiamine treatment.

    The present study examined the factor structure of a Malay version of the Body Appreciation Scale (BAS), a recently developed scale for the assessment of positive body image that has been shown to have a unidimensional structure in Western settings. Results of exploratory and confirmatory factor analyses based on data from community sample of 591 women in Kuala Lumpur, Malaysia, failed to support a unidimensional structure for the Malay BAS. Results of a confirmatory factor analysis suggested two stable factors, which were labelled 'General Body Appreciation' and 'Body Image Investment'. Multi-group analysis showed that the two-factor structure was invariant for both Malaysian Malay and Chinese women, and that there were no significant ethnic differences on either factor. Results also showed that General Body Appreciation was significant negatively correlated with participants' body mass index. These results are discussed in relation to possible cross-cultural differences in positive body image.

    A tendency toward the rapid yen appreciation since spring 1995 has affected various fields of the economic society of Japan. From a broader view, it is discussed whether the Japanese economic system itself is right or wrong, and that the post-war economic system and regulation system should be largely reviewed. In a short term, the yen appreciation largely affects the export industry and is markedly influential to macro economy. At present, the yen is not as high as that in 1995, but a lot of economists assume a tendency toward medium- and long-term yen appreciation. Therefore, this paper analyzed what kinds of influences the exchange fluctuation brings to the Japanese economy and energy supply/demand. It was clarified what kinds of problems will appear in the energy industry, in particular, on the assumption that the yen will keep high in medium- and long-term. The report consists of parts 1 and 2. Described were `Simulational analysis of yen appreciation` in Part 1 and `Yen appreciation and international issues` in Part 2. 12 figs., 5 tabs.

    To investigate the effect on glycemic control of improving diabetic gastroparesis, we evaluated symptoms (scored), gastric motor functions (solid and liquid gastric emptying studies and electrogastrography), and glycemic control in 11 patients with diabetic gastroparesis (5 men, 6 women, 50.4 +/- 4.5 years old) before and after treatment with cisapride (15 mg/day p.o., 12 weeks). None of the patients had organic abnormalities on gastrointestinal endoscopy. The dysmotility symptom score (maximum: 18) on cisapride significantly improved from 13.1 to 4.0 (p instant noodles labeled with 37 MBq (1 mCi) technetium-99m (both p < 0.05). Liquid gastric emptying, evaluated using a sulfamethizole technique, also improved but not significantly. Electrogastrography revealed no significant changes after treatment, but the postprandial rate of normal frequency waves tended to increase. Glycemic control was assessed based on HbA1C, fructosamine and M value. There were no significant changes in glycemic control after treatment with cisapride. We conclude that long-term administration of cisapride reduced dysmotility symptoms and improved solid and liquid gastric emptying without adversely affecting glycemic control.

    Full Text Available In this paper I use the concepts “understanding of science” and “appreciation of science” to analyze selected case studies of current science communication in Denmark. The Danish science communication system has many similarities with science communication in other countries: the increasing political and scientific interest in science communication, the co-existence of many different kinds of science communication, and the multiple uses of the concepts of understanding vs. appreciation of science. I stress the international aspects of science communication, the national politico-scientific context as well as more local contexts as equally important conditions for understanding current Danish science communication.

    The discord within nursing regarding the definition of nursing science has created great angst, particularly for those who view nursing science as a body of knowledge derived from theories specific to its unique concerns. The purpose of this brief article is to suggest a perspective and process grounded in appreciation of wholeness that may offer a way forward for proponents of a unitary-transformative nursing science that transcends the discord. This way forward is guided by principles of fostering dissent without contempt, generating a well-imagined future, and garnering appreciatively inspired action for change.

  14. SOIL AGROCHEMICAL PROPERTIES IMPROVEMENT IN LONG TERM FIELD EXPERIMENT WITH FERTILIZERS

    Directory of Open Access Journals (Sweden)

    Mihaela Lungu

    2005-10-01

    Full Text Available Soil fertility is studied in long-term field experiments. Researches are carried out in several agricultural research stations, out of which the following have been chosen for the present paper: Albic Luvisol* at Albota; Haplic Phaeozem at Fundulea; Chromic Luvisol at Şimnic; Calcic Chernozem at Secuieni; and Haplic Chernozem at Podu Iloaiei. Long term fertilization with nitrogen and phosphorus generally improved the soil agrochemical properties. The evolution of organic matter, nitrogen, mobile phosphorus and potassium, and mobile microelements contents were studied, using the standardized method used in the ICPA laboratories. The organic matter and total nitrogen contents didn’t change significantly under the nitrogen and phosphorus long-term fertilization influence. The mobile phosphorus contents have the tendency to grow very significantly with the growth of phosphorus fertilizers. At the same time, slight depletions of these contents are registered as the high nitrogen doses from fertilizers stimulate plant growth and, obviously, nutritive elements absorption. Mobile potassium contents changes very little, with insignificant differences. Significant depletions are registered only with high fertilizers doses, due to the stimulation of the nutritive elements absorption in plants. Microelements contents don’t change almost at all. They are within the normal content limits and no excess or deficiency was registered, in any of the studied stations. For the agricultural practice, economical studies are recommended, about how high fertilizing expenses are covered by the yield growth. Not the least, production quality study in different variants of mineral fertilization could prove interesting.

    2013-08-01

    Many studies have suggested that structural and functional cerebral neuroplastic processes result from long-term musical training, which in turn may produce cognitive differences between musicians and non-musicians. We aimed to investigate whether intensive, long-term musical practice is associated with improvements in three different forms of visual attention ability: selective, divided and sustained attention. Musicians from symphony orchestras (n=38) and non-musicians (n=38), who were comparable in age, gender and education, were submitted to three neuropsychological tests, measuring reaction time and accuracy. Musicians showed better performance relative to non-musicians on four variables of the three visual attention tests, and such an advantage could not solely be explained by better sensorimotor integration. Moreover, in the group of musicians, significant correlations were observed between the age at the commencement of musical studies and reaction time in all visual attention tests. The results suggest that musicians present augmented ability in different forms of visual attention, thus illustrating the possible cognitive benefits of long-term musical training.

  16. Management of remanent lifetime. Short-term benefits of the maintenance evaluation and improvement programme

    International Nuclear Information System (INIS)

    Sainero Garcia, J.

    1993-01-01

    Remanent Lifetime Management, which is scientifically based on knowing the degradatory phenomena associated with aging, today allows us to optimize plant life through a long-term maintenance strategy combining preventive maintenance and condition monitoring programmes. Within a project for Remanent Lifetime Management (RLM), the determination of methods of control and mitigation of degradations due to aging depends on the programme of Maintenance Evaluation and Improvement (MEI). This programme, underpinned by the analysis of degradatory phenomena to which plant components are subjected, evaluates current maintenance practices and defines the complementary actions which would facilitate establishment of a long-term strategy to control aging. Together with this main objective of the RLM project, the MEI programme achieves short-term benefits since, right from the beginning, it offers solutions to mitigate and guard against degradations in crucial plant components, and generally sets out a programme to control aging. The MEI programme further serves as a tool to reach the final objectives of the new 10CFR50.65 rule, 'Requirements for Maintenance Programs for NPPs'. The MEI always offers the option should the Utility Owner decide to extend plant life. (author)

  17. Is Fibre an Effective Strategy to Improve Laxation in Long-Term Care Residents?

    Dahl, Wendy J; Mendoza, Daniela Rivero

    2018-03-01

    The high prevalence of constipation in long-term care (LTC) residents has been a long-standing issue for caregivers, attending health professionals, and the residents themselves. The traditional medical response has been to utilize pharmaceutical laxatives, enemas, and suppositories for treatment. The purpose of this review was to determine if fibre supplementation (including fibre added to foods) is effective in increasing stool frequency, improving stool consistency, and decreasing laxative use in LTC residents. A systematic search was conducted using PubMed and CINAHL databases, inclusive to March 2017. Search terms included: "long-term care" or "nursing home" AND "fiber (fibre)," "bran," "psyllium," "inulin," or "prebiotic." Intervention trials of fibre supplementation with ≥5 LTC residents were included. The search generated 456 articles following removal of duplicates; 8 studies met the inclusion criteria. Three additional trials were identified through a hand search of references of pertinent articles. Current evidence suggests that added fibre may be effective in increasing stool frequency and/or decreasing laxative use in LTC residents and, thus, may lessen the burden of constipation. However, randomized controlled trials are needed to clearly demonstrate the effects of adding fibre to foods, particularly insoluble and less fermentable sources, on constipation in LTC residents.

  18. Shifting the Paradigm for Long Term Monitoring at Legacy Sites to Improve Performance while Reducing Cost

    A major issue facing many government and private industry sites that were previously contaminated with radioactive and chemical wastes is that often the sites cannot be cleaned up enough to permit unrestricted human access. These sites will require long-term management, in some cases indefinitely, leaving site owners with the challenge of protecting human health and environmental quality in a cost effective manner. Long-term monitoring of groundwater contamination is one of the largest projected costs in the life cycle of environmental management at the Savannah River Site (SRS), the larger DOE complex, and many large federal and private sites. Currently, most monitoring strategies are focused on laboratory measurements of contaminants measured in groundwater samples collected from wells. This approach is expensive, and provides limited and lagging information about the effectiveness of cleanup activities and the behavior of the residual contamination. Over the last twenty years, DOE and other federal agencies have made significant investments in the development of various types of sensors and strategies that would allow for remote analysis of contaminants in groundwater, but these approaches do not promise significant reductions in risk or cost. Scientists at SRS have developed a new paradigm to simultaneously improve the performance of long term monitoring systems while lowering the overall cost of monitoring. This alternative approach incorporates traditional point measurements of contaminant concentration with measurements of controlling variables including boundary conditions, master variables, and traditional plume/contaminant variables. Boundary conditions are the overall driving forces that control plume movement and therefore provide leading indication to changes in plume stability. These variables include metrics associated with meteorology, hydrology, hydrogeology, and land use. Master variables are the key variables that control the chemistry of the

    Remote ischemic preconditioning (RIPre) can prevent myocardial injury. The purpose of this study was to assess the beneficial effects of long-term regular RIPre on human arteries. Forty patients scheduled for coronary artery bypass graft (CABG) surgery were assigned randomly to a RIPre group (n=20) or coronary heart disease (CHD) group (n=20). Twenty patients scheduled for mastectomy were enrolled as a control group. RIPre was achieved by occluding arterial blood flow 5 min with a mercury sphygmomanometer followed by a 5-min reperfusion period, and this was repeated 4 times. The RIPre procedure was repeated 3 times a day for 20 days. In all patients, arterial fragments discarded during surgery were collected to evaluate endothelial function by flow-mediated dilation (FMD), CD34{sup +} monocyte count, and endothelial nitric oxide synthase (eNOS expression). Phosphorylation levels of STAT-3 and Akt were also assayed to explore the underlying mechanisms. Compared with the CHD group, long-term regular RIPre significantly improved FMD after 20 days (8.5±2.4 vs 4.9±4.2%, P<0.05) and significantly reduced troponin after CABG surgery (0.72±0.31 and 1.64±0.19, P<0.05). RIPre activated STAT-3 and increased CD34{sup +} endothelial progenitor cell counts found in arteries. Long-term, regular RIPre improved endothelial function in patients with CHD, possibly due to STAT-3 activation, and this may have led to an increase in endothelial progenitor cells.

    Subarachnoid hemorrhage results in significant long-lasting neurologic sequelae. Here, we investigated whether human albumin improves long-term outcomes in experimental subarachnoid hemorrhage and whether neurovascular remodeling is involved in the protection of albumin. Laboratory investigation. Hospital research laboratory. Male Sprague-Dawley rats. Rats underwent subarachnoid hemorrhage by endovascular perforation. Albumin of either 0.63 or 1.25 g/kg was injected IV immediately after the surgery. Modified Garcia test, beam-walking test, novel object recognition, and Morris water maze were employed to determine the behavioral deficits. The effects of albumin on early neurovascular dysfunction and chronic synaptic plasticity were also studied. Both doses of albumin significantly improved the sensorimotor scores (F = 31.277; p = 0.001) and cognitive performance (F = 7.982; p = 0.001 in novel object recognition test; and F = 3.431; p = 0.026 in the latency analysis of Morris water maze test) for at least 40 days after subarachnoid hemorrhage. There were remarkable microvasculature hypoperfusion, intracranial pressure rise, early vasoconstriction, neural apoptosis, and degeneration in subarachnoid hemorrhage rats, with albumin significantly attenuating such neurovascular dysfunction. Furthermore, albumin markedly prevented blood-brain barrier disruption, as indicated by less blood-brain barrier leakage, preserved blood-brain barrier-related proteins, and dampened gelatinase activities. The expressions of key synaptic elements were up-regulated with albumin supplementation in both acute and chronic phases. Accordingly, a higher dendritic spine density was observed in the prefrontal and hippocampal areas of albumin-treated subarachnoid hemorrhage animals. Albumin at low-to-moderate doses markedly improves long-term neurobehavioral sequelae after subarachnoid hemorrhage, which may involve an integrated process of neurovascular remodeling.

    Full Text Available Abstract Introduction This study examined the short- and long-term effects of a quality improvement collaborative on patient outcomes, professional performance, and structural aspects of chronic care management of type 2 diabetes in an integrated care setting. Methods Controlled pre- and post-intervention study assessing patient outcomes (hemoglobin A1c, cholesterol, blood pressure, weight, blood lipid levels, and smoking status, professional performance (guideline adherence, and structural aspects of chronic care management from baseline up to 24 months. Analyses were based on 1,861 patients with diabetes in six intervention and nine control regions representing 37 general practices and 13 outpatient clinics. Results Modest but significant improvement was seen in mean systolic blood pressure (decrease by 4.0 mm Hg versus 1.6 mm Hg and mean high density lipoprotein levels (increase by 0.12 versus 0.03 points at two-year follow up. Positive but insignificant differences were found in hemoglobin A1c (0.3%, cholesterol, and blood lipid levels. The intervention group showed significant improvement in the percentage of patients receiving advice and instruction to examine feet, and smaller reductions in the percentage of patients receiving instruction to monitor blood glucose and visiting a dietician annually. Structural aspects of self-management and decision support also improved significantly. Conclusions At a time of heightened national attention toward diabetes care, our results demonstrate a modest benefit of participation in a multi-institutional quality improvement collaborative focusing on integrated, patient-centered care. The effects persisted for at least 12 months after the intervention was completed. Trial number http://clinicaltrials.gov Identifier: NCT 00160017

    Full Text Available The appreciation of the performances of the enterprise are made, as a rule, by ways of indicators which are of accounting type, the result of financial exercise, profit or loss, being mostly used. This result can be determined differently, according to approaches of patrimonial, economic or financial nature. Due to the handling potential of this indicator, the attention of the analysts focused in time also on other computing patterns, uninfluenced by the accounting methods and techniques used by the enterprise. The investors’ need of information determined the conception of some performance computing models based on the concept of creating value for the shareholders. Among these, those which express the ability of the enterprise to create value on long term, based on discounted cash flow, are the most appreciated. Nevertheless, within the Romanian economic context, the most used performance indicators are still of accounting nature for being accessible and understandable.

  3. Unmasking “Alive:” Children’s Appreciation of a Concept Linking All Living Things

    2009-01-01

    Decades of research have documented in school-aged children a persistent difficulty apprehending an overarching biological concept that encompasses animate entities like humans and non-human animals, as well as plants. This has led many researchers to conclude that young children have yet to integrate plants and animate entities into a concept LIVING THING. However, virtually all investigations have used the word “alive” to probe children’s understanding, a term that technically describes all living things, but in practice is often aligned with animate entities only. We show that when “alive” is replaced with less ambiguous probes, children readily demonstrate knowledge of an overarching concept linking plants with humans and non-human animals. This work suggests that children have a burgeoning appreciation of this fundamental biological concept, and that the word “alive” paradoxically masks young children’s appreciation of the concept to which it is meant to refer.

    Highlights: • Improved multi-objective gravitational search algorithm. • An elite archive set is proposed to guide evolutionary process. • Neighborhood searching mechanism to improve local search ability. • Adopt chaotic mutation for avoiding premature convergence. • Propose feasible space method to handle hydro plant constrains. - Abstract: With growing concerns about energy and environment, short-term economic environmental hydrothermal scheduling (SEEHS) plays a more and more important role in power system. Because of the two objectives and various constraints, SEEHS is a complex multi-objective optimization problem (MOOP). In order to solve the problem, we propose an improved multi-objective gravitational search algorithm (IMOGSA) in this paper. In IMOGSA, the mass of the agent is redefined by multiple objectives to make it suitable for MOOP. An elite archive set is proposed to keep Pareto optimal solutions and guide evolutionary process. For balancing exploration and exploitation, a neighborhood searching mechanism is presented to cooperate with chaotic mutation. Moreover, a novel method based on feasible space is proposed to handle hydro plant constraints during SEEHS, and a violation adjustment method is adopted to handle power balance constraint. For verifying its effectiveness, the proposed IMOGSA is applied to a hydrothermal system in two different case studies. The simulation results show that IMOGSA has a competitive performance in SEEHS when compared with other established algorithms

    To date, we still lack disease-modifying therapies for Alzheimer's disease (AD). Here, we report that long-term administration of benfotiamine improved the cognitive ability of patients with AD. Five patients with mild to moderate AD received oral benfotiamine (300 mg daily) over 18 months. All patients were examined by positron emission tomography with Pittsburgh compound B (PiB-PET) and exhibited positive imaging with β-amyloid deposition, and three received PiB-PET imaging at follow-up. The five patients exhibited cognitive improvement as assayed by the Mini-Mental Status Examination (MMSE) with an average increase of 3.2 points at month 18 of benfotiamine administration. The three patients who received follow-up PiB-PET had a 36.7% increase in the average standardized uptake value ratio in the brain compared with that in the first scan. Importantly, the MMSE scores of these three had an average increase of 3 points during the same period. Benfotiamine significantly improved the cognitive abilities of mild to moderate AD patients independently of brain amyloid accumulation. Our study provides new insight to the development of disease-modifying therapy.

  14. Cognitive mechanisms for explaining dynamics of aesthetic appreciation

    Carbon, Claus-Christian

    2011-01-01

    For many domains aesthetic appreciation has proven to be highly reliable. Evaluations of facial attractiveness, for instance, show high internal consistencies and impressively high inter-rater reliabilities, even across cultures. This indicates general mechanisms underlying such evaluations. It is, however, also obvious that our taste for specific objects is not always stable—in some realms such stability is hardly conceivable at all since aesthetic domains such as fashion, design, or art are inherently very dynamic. Gaining insights into the cognitive mechanisms that trigger and enable corresponding changes of aesthetic appreciation is of particular interest for psychologists as this will probably reveal essential mechanisms of aesthetic evaluations per se. The present paper develops a two-step model, dynamically adapting itself, which accounts for typical dynamics of aesthetic appreciation found in different research areas such as art history, philosophy, and psychology. The first step assumes singular creative sources creating and establishing innovative material towards which, in a second step, people adapt by integrating it into their visual habits. This inherently leads to dynamic changes of the beholders— aesthetic appreciation. PMID:23145254

    Treatments that improve function in late phase after stroke are urgently needed. We assessed whether multimodal interventions based on rhythm-and-music therapy or horse-riding therapy could lead to increased perceived recovery and functional improvement in a mixed population of individuals in late phase after stroke. Participants were assigned to rhythm-and-music therapy, horse-riding therapy, or control using concealed randomization, stratified with respect to sex and stroke laterality. Therapy was given twice a week for 12 weeks. The primary outcome was change in participants' perception of stroke recovery as assessed by the Stroke Impact Scale with an intention-to-treat analysis. Secondary objective outcome measures were changes in balance, gait, grip strength, and cognition. Blinded assessments were performed at baseline, postintervention, and at 3- and 6-month follow-up. One hundred twenty-three participants were assigned to rhythm-and-music therapy (n=41), horse-riding therapy (n=41), or control (n=41). Post-intervention, the perception of stroke recovery (mean change from baseline on a scale ranging from 1 to 100) was higher among rhythm-and-music therapy (5.2 [95% confidence interval, 0.79-9.61]) and horse-riding therapy participants (9.8 [95% confidence interval, 6.00-13.66]), compared with controls (-0.5 [-3.20 to 2.28]); P =0.001 (1-way ANOVA). The improvements were sustained in both intervention groups 6 months later, and corresponding gains were observed for the secondary outcomes. Multimodal interventions can improve long-term perception of recovery, as well as balance, gait, grip strength, and working memory in a mixed population of individuals in late phase after stroke.

    State and local air quality forecasters across the United States use air quality forecasts from the National Air Quality Forecasting Capability (NAQFC) at the National Oceanic and Atmospheric Administration (NOAA) as one of the key tools to protect the public from adverse air pollution related health effects by dispensing timely information about air pollution episodes. This project funded by the National Aeronautics and Space Administration (NASA) aims to enhance the decision-making process by improving the accuracy of NAQFC short-term predictions of ground-level particulate matter of less than 2.5 µm in diameter (PM2.5) by exploiting NASA Earth Science Data with chemical data assimilation. The NAQFC is based on the Community Multiscale Air Quality (CMAQ) model. To improve the initialization of PM2.5 in CMAQ, we developed a new capability in the community Gridpoint Statistical Interpolation (GSI) system to assimilate Terra/Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical depth (AOD) retrievals in CMAQ. Specifically, we developed new capabilities within GSI to read/write CMAQ data, a forward operator that calculates AOD at 550 nm from CMAQ aerosol chemical composition and an adjoint of the forward operator that translates the changes in AOD to aerosol chemical composition. A generalized background error covariance program called "GEN_BE" has been extended to calculate background error covariance using CMAQ output. The background error variances are generated using a combination of both emissions and meteorological perturbations to better capture sources of uncertainties in PM2.5 simulations. The newly developed CMAQ-GSI system is used to perform daily 24-h PM2.5 forecasts with and without data assimilation from 15 July to 14 August 2014, and the resulting forecasts are compared against AirNOW PM2.5 measurements at 550 stations across the U. S. We find that the assimilation of MODIS AOD retrievals improves initialization of the CMAQ model

    In this paper we demonstrate significant improvements to the stability of the monochromatic X-ray beam intensity on several beamlines at Diamond, using a modulation of the pitch axis of the DCM with a piezoelectric actuator. The modulation is detected on an intensity diagnostic (e.g. an ion chamber) using a software lock-in technique. The detected amplitude and phase are used in a feedback to keep the DCM at the peak of the rocking curve, or any arbitrary position 'off-peak' which might be desired to detune the DCM and reject unwanted harmonics. A major advantage of this software based system is the great flexibility offered, using standard, readily available instrumentation. Measurements of the short and long-term performance of the feedback on several beamlines are presented, and the limitations of such a feedback are discussed.

This study investigated the long-term effect of adding bendamustine to a conditioning regimen on survival, rate of engraftment, immune recovery and GvHD after allogeneic stem cell transplantation (alloSCT) in CLL patients. These outcomes were compared with the fludarabine, cyclophosphamide and rituximab (FCR) conditioning regimen. We reviewed the data for 89 CLL patients treated on three trials at our institution. Twenty-six (29%) patients received bendamustine, fludarabine and rituximab (BFR) and 63 (71%) received FCR. Patient characteristics were similar in both groups. Ten (38%) BFR-treated patients vs only two (3%) FCR-treated patients did not experience severe neutropenia (P=CLL patients is associated with improved survival and lower mortality, myelosuppression, and GvHD.

It discusses how these new capabilities may be exploited for thermal source term generation for use in repository performance assessment modeling. SNF historical discharges have been exhaustively tracked, and significant effort has gone into capturing, verifying, and electronically managing spent fuel inventory data. Future discharge projections are produced annually by the Energy Information Administration (EIA) using sophisticated computer models. The output of these models is coupled with annually updated SNF historical discharges to produce what is referred to as the open-quotes reactor database.close quotes This database and related data are published in a variety of ways including on magnetic media for consistent use by analysts or other interested parties

    Atypical neuroleptics seem to be more beneficial than typical ones with respect to long-term neuropsychological functioning. Thus, most studies focus on the long-term effects of neuroleptics. We were interested in whether atypical neuroleptic treatment is also superior to typical drugs over relatively short periods of time. We studied 20 schizophrenic patients [10 males, mean age 35.5 years, mean Brief Psychiatric Rating Scale (BPRS) score at entry 58.9] admitted to our hospital with acute psychotic exacerbation. Nine of them were treated with typical and 11 with atypical neuroleptics. In addition, 14 healthy drug-free subjects (6 males, mean age 31.2 years) were enrolled in the study and compared to the patients. As neuropsychological tools, a divided attention test, the Vienna reaction time test, the Benton visual retention test, digit span and a Multiple Choice Word Fluency Test (MWT-B) were used during the first week after admission, within the third week and before discharge (approximately 3 months). Patients scored significantly worse than healthy controls on nearly all tests (except Vienna reaction time). Clinical ratings [BPRS and Positive and Negative Symptom Scale for Schizophrenia (PANSS)] improved markedly (p divided attention task (r = 0.705, p = 0.034). Neuropsychological functioning (explicit memory, p divided attention, p < 0.05) moderately improved for both groups under treatment but without a significant difference between atypical and typical antipsychotic drugs. Over short periods of time (3 months), neuropsychological disturbances in schizophrenia seem to be moderately responsive to both typical and atypical neuroleptics. Copyright 2002 S. Karger AG, Basel

This paper describes a long-term (1918–2011 grid-based (1/8° surface hydrological dataset for Texas at a daily time step based on simulations from the Variable Infiltration Capacity (VIC hydrological model. The model was calibrated and validated against observed streamflow over 10 Texas river basins. The simulated soil moisture was also evaluated using in situ observations. Results suggest that there is a decreasing trend in precipitation and an increasing trend in temperature in most of the basins. Droughts and floods were reconstructed and analyzed. In particular, the spatially distributed severity and duration of major Texas droughts were compared to identify new characteristics. The modeled flood recurrence interval and the return period were also compared with observations. Results suggest the performance of extreme flood simulations needs further improvement. This dataset is expected to serve as a benchmark which may contribute to water resources management and to mitigating agricultural drought, especially in the context of understanding the effects of climate change on crop yield in Texas.

    Body image, a multidimensional construct, affects women in myriad ways. Existing scholarship has established a relationship between body image and negative mental and sexual health outcomes and suggests that it may also be related to physical health outcomes. The purpose of the study reported in this article was to explore relationships between body appreciation, a multidimensional measure of body image, and self-perceived physical health among a sample of emerging adult women (N = 399). In this sample, body appreciation was positively and significantly related to self-perceived physical health. This study contributes to a growing body of literature on the consequences of body image among women and can be used to inform interventions aimed at improving the well-being of women. © 2017 National Association of Social Workers.

    We aimed to determine whether ethnicity-specific birthweight distributions more accurately identify newborns at risk for short-term neonatal morbidity associated with small for gestational age (SGA) birth than population-based distributions not stratified on ethnicity. We examined 100,463 singleton term infants born to parents in Washington State between Jan. 1, 2006, and Dec. 31, 2008. Using multivariable logistic regression models, we compared the ability of an ethnicity-specific growth distribution and a population-based growth distribution to predict which infants were at increased risk for Apgar score distributions had the highest rates of each of the adverse outcomes assessed-more than double those of infants only considered SGA by the population-based standards. When controlling for mother's age, parity, body mass index, education, gestational age, mode of delivery, and marital status, newborns considered SGA by ethnicity-specific birthweight distributions were between 2 and 7 times more likely to suffer from the adverse outcomes listed above than infants who were not SGA. In contrast, newborns considered SGA by population-based birthweight distributions alone were at no higher risk of any adverse outcome except hypothermia (adjusted odds ratio, 2.76; 95% confidence interval, 1.68-4.55) and neonatal intensive care unit admission (adjusted odds ratio, 1.40; 95% confidence interval, 1.18-1.67). Ethnicity-specific birthweight distributions were significantly better at identifying the infants at higher risk of short-term neonatal morbidity, suggesting that their use could save resources and unnecessary parental anxiety.

    Full Text Available Long-term scheduling of large cascade hydropower stations (LSLCHS is a complex problem of high dimension, nonlinearity, coupling and complex constraint. In view of the above problem, we present an improved differential evolution (iLSHADE algorithm based on LSHADE, a state-of-the-art evolutionary algorithm. iLSHADE uses new mutation strategies “current to pbest/2-rand” to obtain wider search range and accelerate convergence with the preventing individual repeated failure evolution (PIRFE strategy. The handling of complicated constraints strategy of ε-constrained method is presented to handle outflow, water level and output constraints in the cascade reservoir operation. Numerical experiments of 10 benchmark functions have been done, showing that iLSHADE has stable convergence and high efficiency. Furthermore, we demonstrate the performance of the iLSHADE algorithm by comparing it with other improved differential evolution algorithms for LSLCHS in four large hydropower stations of the Jinsha River. With the applications of iLSHADE in reservoir operation, LSLCHS can obtain more power generation benefit than other alternatives in dry, normal, and wet years. The results of numerical experiments and case studies show that the iLSHADE has a distinct optimization effect and good stability, and it is a valid and reliable tool to solve LSLCHS problem.

    Objective: Since 1979, our institution has treated locally advanced rectal cancer with preoperative irradiation followed by resection with or without intraoperative radiation therapy (IORT). In 1986, our preoperative treatment policy was changed to include bolus 5-FU chemotherapy concurrent with irradiation in hopes of improving resectability, downstaging and/or local control rates. We report the long-term results with the addition of 5-FU chemotherapy to preoperative irradiation. Materials and Methods: From 1979 - 1994, 200 patients with locally advanced rectal carcinoma (primary or recurrent) received preoperative irradiation, resection and IORT if indicated. Bolus 5-FU (500mg/m 2 /day) chemotherapy was administered for three days during weeks one and five of irradiation. The change in treatment policy was limited to the addition of 5-FU chemotherapy: the radiation techniques (four-field), doses (50.4 Gy), and indications for intraoperative radiation (microscopic residual, gross residual, tumor adherence) remained constant. The median follow-up for the entire group of patients was 33 months (.95 months - 199 months), and the minimum follow-up was 1.5 years. Tabular results are 5-year actuarial calculations. Results: One hundred and five patients received preoperative 5-FU chemotherapy and irradiation whereas 95 patients underwent preoperative irradiation alone. Sixty-five percent of the patients were able to undergo complete resections, and 53% had transmural disease upon pathologic examination. The addition of chemotherapy did not affect the rates of resectability or tumor downstaging. However, the 10-year local control rate was significantly improved for those patients who received preoperative chemotherapy: 77% vs. 44% (p<0.01) (see figure). When stratified by extent of resection and stage, those patients who underwent complete resections or had transmural disease had significantly improved local control rates when compared to the non-chemotherapy group: No

    Many of the world's population have hearing loss in one ear; current statistics indicate that up to 10% of the population may be affected. Although the detrimental impact of bilateral hearing loss, hearing aids, and cochlear implants upon music appreciation is well recognized, studies on the influence of single-sided deafness (SSD) are sparse. We sought to investigate whether a single-sided hearing loss can cause problems with music appreciation, despite normal hearing in the other ear. A tailored questionnaire was used to investigate music appreciation for those with SSD. We performed a retrospective survey of a population of 51 adults from a University Hospital Audiology Department SSD clinic. SSD was predominantly adult-onset sensorineural hearing loss, caused by a variety of etiologies. Analyses were performed to assess for statistical differences between groups, for example, comparing music appreciation before and after the onset of SSD, or before and after receiving hearing aid(s). Results demonstrated that a proportion of the population experienced significant changes to the way music sounded; music was found to sound more unnatural (75%), unpleasant (71%), and indistinct (81%) than before hearing loss. Music was reported to lack the perceptual qualities of stereo sound, and to be confounded by distortion effects and tinnitus. Such changes manifested in an altered music appreciation, with 44% of participants listening to music less often, 71% of participants enjoying music less, and 46% of participants reporting that music played a lesser role in their lives than pre-SSD. Negative effects surrounding social occasions with music were revealed, along with a strong preference for limiting background music. Hearing aids were not found to significantly ameliorate these effects. Results could be explained in part through considerations of psychoacoustic changes intrinsic to an asymmetric hearing loss and impaired auditory scene analysis. Given the prevalence of

    Nowadays there is the hope that neuroscientific findings will contribute to the improvement of building design in order to create environments which satisfy man's demands. This can be achieved through the understanding of neurophysiological correlates of architectural perception. To this aim, the electroencephalographic (EEG) signals of 12 healthy subjects were recorded during the perception of three immersive virtual reality environments (VEs). Afterwards, participants were asked to describe their experience in terms of Familiarity, Novelty, Comfort, Pleasantness, Arousal, and Presence using a rating scale from 1 to 9. These perceptual dimensions are hypothesized to influence the pattern of cerebral spectral activity, while Presence is used to assess the realism of the virtual stimulation. Hence, the collected scores were used to analyze the Power Spectral Density (PSD) of the EEG for each behavioral dimension in the theta, alpha and mu bands by means of time-frequency analysis and topographic statistical maps. Analysis of Presence resulted in the activation of the frontal-midline theta, indicating the involvement of sensorimotor integration mechanisms when subjects expressed to feel more present in the VEs. Similar patterns also characterized the experience of familiar and comfortable VEs. In addition, pleasant VEs increased the theta power across visuomotor circuits and activated the alpha band in areas devoted to visuospatial exploration and processing of categorical spatial relations. Finally, the de-synchronization of the mu rhythm described the perception of pleasant and comfortable VEs, showing the involvement of left motor areas and embodied mechanisms for environment appreciation. Overall, these results show the possibility to measure EEG correlates of architectural perception involving the cerebral circuits of sensorimotor integration, spatial navigation, and embodiment. These observations can help testing architectural hypotheses in order to design

    This paper studied effects of yen appreciation on the Japanese economy and changes in energy demand when assuming the medium-term yen appreciation trend, and subjects in the energy industry. The paper also refers to the trend of the Asian material industry largely influencing the energy supply/demand, the risk hedge problem of the exchange, and international cooperation and business development of the energy industry. The energy industry is extremely high in public interest and is rice of the industry. Therefore, the development of the business has focused on the domestic market. However, such a recognition is forced to be changed by waves of the worldwide deregulation. Discussions on foreign/domestic price differences caused by high yen and a series of deregulation policy in the energy industry affected thereby may be concrete signs. The subject in the energy industry under the yen appreciation is that the energy industry will be close to common sense in general industrial circles and change to an industry which is strong and internationally competitive enough to brave the exchange variation. 101 refs., 104 figs., 31 tabs.

    To address the organization of conversations in oncology visits by taking an "interaction order" perspective and asking how these visits are intrinsically organized. Conversation analysis. Using audio recordings of talk in oncology visits involving patients with non-small cell lung cancer, we identify and analyze an "appreciation sequence" that is designed to elicit patients' understanding and positive assessment of treatments in terms of their prolongation of life. An "appreciation sequence," regularly initiated after the delivery of scan results and/or treatment recommendations, simultaneously reminds patients of their mortality while suggesting that the treatment received has prolonged their lives, and in some cases significantly beyond the median time of survival. We explore the functions of the appreciation sequence for cancer care and set the stage for considering where and when physicians have choices about the order and direction the talk can take and how to allocate time for end of life and quality of life conversations.

    Full Text Available Many large projects held over the last few decades in Europe have been based on the enhancement of community goods as a strategy to put in place sustainable urban regeneration. The inclusive nature of these goods and the social importance of the related decision-making processes suggests the need to involve the relevant community and to take into account its intentions and wishes regarding planning and organization. Therefore, before even starting to plan possible interventions, it is crucial to know what the members of the community think about the good in terms of social appreciation, in order to achieve socially sustainable choices. This paper offers a method to measure the social appreciation of community goods and describes the following: (a deliberative esteem value technology to measure the social appreciation based on a combination between stated preference techniques and deliberative methods; (b the criterion and methodology of the valuation technique proposed; and (c an experimental application of the valuation technique pertinent to the specific case of the East Elevated Expressway of Rome.

    People with dementia who are being cared for in long-term care settings are often not engaged in meaningful activities. Offering them activities which are tailored to their individual interests and preferences might improve their quality of life and reduce challenging behaviour. ∙ To assess the effects of personally tailored activities on psychosocial outcomes for people with dementia living in long-term care facilities.∙ To describe the components of the interventions.∙ To describe conditions which enhance the effectiveness of personally tailored activities in this setting. We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's Specialized Register, on 16 June 2017 using the terms: personally tailored OR individualized OR individualised OR individual OR person-centred OR meaningful OR personhood OR involvement OR engagement OR engaging OR identity. We also performed additional searches in MEDLINE (Ovid SP), Embase (Ovid SP), PsycINFO (Ovid SP), CINAHL (EBSCOhost), Web of Science (ISI Web of Science), ClinicalTrials.gov, and the World Health Organization (WHO) ICTRP, to ensure that the search for the review was as up to date and as comprehensive as possible. We included randomised controlled trials and controlled clinical trials offering personally tailored activities. All interventions included an assessment of the participants' present or past preferences for, or interests in, particular activities as a basis for an individual activity plan. Control groups received either usual care or an active control intervention. Two authors independently checked the articles for inclusion, extracted data and assessed the methodological quality of included studies. For all studies, we assessed the risk of selection bias, performance bias, attrition bias and detection bias. In case of missing information, we contacted the study authors. We included eight studies with 957 participants. The mean age of participants in the studies ranged from 78 to 88

    Full Text Available The method of aesthetic transfer is a modern teaching method in art education. It emphasizes the pedagogic value of the aesthetic experience. It is a comprehensive method, as it encompasses different parameters of art didactics. It affects lesson time allocation and determines content, methods, and teaching modes. It also affects motivation and final evaluation. The essence of the method of aesthetic transfer lies in transferring aesthetic messages from the artwork to students. The foundation and condition for a successful implementation of the method of aesthetic transfer is a high-quality art appreciation. There are several ways and methods for successfully developing art appreciation, the common objective of all being to allow students to see, perceive, and enjoy a work of art. Thus they enrich their artistic and aesthetic development, and establish a positive attitude towards art, while this method at the same time encourages their own artistic exploration.

    Full Text Available In the contemporary process of teaching fine arts, children’s own creative expression and art appreciation are used to encourage learners towards both perception and reception; consequently, the evaluation and internalization of works of art play an equally important role. In a qualitative empirical research study that takes the form of a case study, we studied the response of children to works of art and their demonstrated communication skills in this. The results have shown that children respond to works of art on multiple levels. With non-standardized narrative group interviews, we observed children’s associations. Children perceived and internalized the given artworks and also put their emotions into words. The study has shown that systematic development of art appreciation among pre-school children can have a positive impact on their communication skills.

    Oral hygiene and health of the institutionalized elderly are frequently described as inadequate. This randomized and single-blinded (outcome evaluation) study compared three types of intervention for improving oral hygiene with a control. The purpose was to investigate whether there were any significant differences between the intervention and control groups. One hundred and six participants living in long-term care homes in South-West Germany were recruited and randomly divided into four groups-three therapy groups and one control group. For all three therapy groups, teeth and dentures were cleaned professionally and individual instruction was given. One of these groups was also re-instructed and remotivated by a dentist (n = 27). One also received help from, and was remotivation by, staff educated in dental hygiene (n = 26). The third therapy group was not remotivated after professional cleaning of teeth and dentures (n = 26). For the control group, there was no intervention (n = 23). The main target clinical data were mean plaque (plaque-control record, O'Leary), gingival bleeding (Ainamo/Bay), and denture hygiene indices. For assessment of the difference between being in an intervention group and in a control group, mixed-model analysis for repeated measurements was performed for each main target variable. In addition, target clinical data were evaluated in long-term follow-up after 3 years. Compared with controls, denture hygiene, plaque, and gingival bleeding indices were significantly lower in the intervention groups over a twelve-week period (mixed model for repeated measurements; P hygiene. However, the effect decreases over time and renewal of the intervention is necessary. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  10. Towards Improved Understanding of Drought and Drought Impacts from Long Term Earth Observation Records

    Drought is a complex natural disaster, which often emerges slowly, but can occur at various time scales and have impacts that are not well understood. Long term observations of drought intensity and frequency are often quantified from precipitation and temperature based indices or modelled estimates of soil water storage. The maturity of satellite based observations has created the potential to enhance the understanding of drought and drought impacts, particularly in regions where traditional data sets are limited by remoteness or inaccessibility, and where drought processes are not well-quantified by models. Long term global satellite data records now provide observations of key hydrological variables, including evaporation modelled from thermal sensors, soil moisture from microwave sensors, ground water from gravity sensors and vegetation condition that can be modelled from optical sensors. This study examined trends in drought frequency, intensity and duration over diverse ecoregions in Canada, including agricultural, grassland, forested and wetland areas. Trends in drought were obtained from the Canadian Drought Monitor as well as meteorological based indices from weather stations, and evaluated against satellite derived information on evaporative stress (Anderson et al. 2011), soil moisture (Champagne et al. 2015), terrestrial water storage (Wang and Li 2016) and vegetation condition (Davidson et al. 2009). Data sets were evaluated to determine differences in how different sensors characterize the hydrology and impacts of drought events from 2003 to 2016. Preliminary results show how different hydrological observations can provide unique information that can tie causes of drought (water shortages resulting from precipitation, lack of moisture storage or evaporative stress) to impacts (vegetation condition) that hold the potential to improve the understanding and classification of drought events.

    The quality of the relationship between postgraduate students and their supervisors often determines the progress of the students. Successful supervision according to students is associated with the expertise of the supervisors and their willingness to share their knowledge with their students. On the other hand, supervisors expect their students to be able to work independently to a large extent. Contradictory expectations of supervisors and postgraduate students can cause delays in the progress of students. The aim of this study was to explore and describe the aspects of the supervisory relationship that postgraduate students in nursing science at a selected university in South Africa appreciate. A qualitative research design with an appreciative inquiry approach was used and 18 students under the guidance of an independent facilitator provided the data during group interviews. Specific personal and professional qualities of the supervisors contribute to a valued supervisory relationship. Regarding personal qualities, the supervisors should show their understanding of the unique circumstances of the students in challenging times. Supervisors should also be expert researchers. The valued relationship refers to an open and trusting relationship between the students and the supervisors. The students' appreciation of the research supervisory relationship contributes to the understanding of the expectations of postgraduate students regarding the support that they need to become scholars in an academic discipline. There is a need for continuing professional development of supervisors to sensitize them about the expectations of the students. © 2015 International Council of Nurses.

    The main objective of this study was to assess the associations between self-reported listening habits and perception of music and speech perception outcomes in quiet and noise for both unilateral cochlear implant (CI) users and bimodal (CI in one ear, hearing aid in contra-lateral ear) users. Information concerning music appreciation was gathered by means of a newly developed questionnaire. Moreover, audiological data (pure-tone audiometry, speech tests in noise and quiet) were gathered and the relationship between speech perception and music appreciation is studied. Bimodal users enjoy listening to music more in comparison with unilateral CI users. Also, music training within rehabilitation is still uncommon, while CI recipients believe that music training might be helpful to maximize their potential with current CI technology. Music training should not be exclusively reserved for the good speech performers. Therefore, a music training program (MTP) that consists of different difficulty levels should be developed. Hopefully, early implementation of MTP in rehabilitation programs can enable adult CI users to enjoy and appreciate music and to maximize their potential with commercially available technology. Furthermore, because bimodal users consider the bimodal stimulation to be the most enjoyable way to listen to music, CI users with residual hearing in the contra-lateral ear should be encouraged to continue wearing their hearing aid in that ear.

    To test whether appreciation of humor might be a non-motor function affected by Parkinson's disease (PD). Thirty-nine PD patients and 38 healthy controls participated in this study. Appreciation of humor and effect of the presentation method utilized were assessed. Sense of humor was evaluated by the sense of humor questionnaire (SHQ-6). Humor appreciation was tested using three methods of presentation: videos, audio sketches and pictorial cartoons, each portraying both obvious and non-obvious humor content. Depression, anxiety, cognition, disease severity and quality of life were measured by standardized questionnaires and correlated with humor outcomes. Patients with PD rated humor content lower than controls on every method of presentation as well as on the SHQ-6 (p = 0.004). The greatest between-group difference was noted when the material was presented visually via pictorial cartoons (p < 0.0001). In addition, obvious humor content was rated higher than non-obvious content by the PD group in all three presentation methods (p < 0.05). The degree of depression and anxiety did not influence these results. Patients with PD have a decreased sense of humor compared to healthy controls. Utilizing audio methods of presentation and humor in an obvious mode appears to be the preferred approach for eliciting responses to humor in a PD population. Copyright © 2011 Elsevier Ltd.

    Full Text Available When monitoring the long history of empirical instruments for environmental attitude measurement, the Two Major Environmental Value model (2-MEV with its two higher order factors: Preservation (PRE and Utilization (UTL has repeatedly and independently been confirmed. PRE assesses preferences towards conservation of nature and the environment, whilst UTL measures preferences towards utilization/exploitation of nature. The latter, however, does not yet include the positive aspects of benefitting from the (enjoyable use of nature. Consequently, besides the established 2-MEV-battery, additional items from an “Appreciation of Nature” (APR scale were applied to an Irish sample of 289 secondary school students (age: M = 14.3 years. Responses to the altogether 30-item battery were applied on an oblique rotation by using the Promax procedure: UTL and PRE appeared as orthogonally related factors, APR correlated to PRE with 0.283. Based on loading scores, the item number for each subscale was further reduced to make the analysis more manageable in educational outreach sites; on those sites, where completing questionnaires may well be quite unpopular, they are very much needed for planning and fine-tuning educational programs. Therefore, extending the 2-MEV scale with an added scale for Appreciation may help: (i to judge participants’ feedback for adjusting/balancing program contents better; and (ii to promote appreciation as a successful strategy for shifting individuals away from their individual exploitative preferences.

Results from the confirmatory factor analysis on 741 university student (431 women; 310 men suggested that a two-factor model with four items deleted represents an adequate description of the data, and best of the factor model proposed. In terms of convergent validity of the scale a negative and significant correlation was found between body appreciation and social appearance anxiety for women and men samples. The Turkish version of the BAS demonstrated adequate internal consistency and composite reliability. Finally, findings from t-test analysis showed that the BAS scores did not differ according to gender.

    According to objectification theory, women become culturally desexualized during midlife and have the opportunity to let go of their propensity to self-objectify. In young women, self-objectification is negatively related to sexual adjustment. Yet little is known about what could ameliorate this relationship or whether it continues after midlife. Body appreciation (i.e., acceptance and positive regard for the body) has been substantiated as a contributor to improved sexual adjustment in young and older women alike. Hence, this study was designed to examine whether it helps mitigate the deleterious effect of self-objectification on sexual function, satisfaction, and distress in women over the age of 50 (n = 193). Path analyses revealed that self-surveillance is related to body shame and appearance anxiety, the latter of which was related to body self-consciousness during sex. In turn, body self-consciousness during sex mediated the relationship between body shame, appearance anxiety, and all three indicators of sexual adjustment. Furthermore, high body appreciation attenuated the negative associations between self-objectification constructs, body self-consciousness during sex, and sexual satisfaction and distress. Overall, this study supports the use of objectification theory in midlife and older women. Sex therapy interventions that incorporate mindfulness and body appreciation principles are discussed.

    Capturing long-range interactions between structural but not sequence neighbors of proteins is a long-standing challenging problem in bioinformatics. Recently, long short-term memory (LSTM) networks have significantly improved the accuracy of speech and image classification problems by remembering useful past information in long sequential events. Here, we have implemented deep bidirectional LSTM recurrent neural networks in the problem of protein intrinsic disorder prediction. The new method, named SPOT-Disorder, has steadily improved over a similar method using a traditional, window-based neural network (SPINE-D) in all datasets tested without separate training on short and long disordered regions. Independent tests on four other datasets including the datasets from critical assessment of structure prediction (CASP) techniques and >10 000 annotated proteins from MobiDB, confirmed SPOT-Disorder as one of the best methods in disorder prediction. Moreover, initial studies indicate that the method is more accurate in predicting functional sites in disordered regions. These results highlight the usefulness combining LSTM with deep bidirectional recurrent neural networks in capturing non-local, long-range interactions for bioinformatics applications. SPOT-disorder is available as a web server and as a standalone program at: http://sparks-lab.org/server/SPOT-disorder/index.php . j.hanson@griffith.edu.au or yuedong.yang@griffith.edu.au or yaoqi.zhou@griffith.edu.au.

  20. Intranasal mesenchymal stem cell treatment for neonatal brain damage: long-term cognitive and sensorimotor improvement.

    Directory of Open Access Journals (Sweden)

    Vanessa Donega

    Full Text Available Mesenchymal stem cell (MSC administration via the intranasal route could become an effective therapy to treat neonatal hypoxic-ischemic (HI brain damage. We analyzed long-term effects of intranasal MSC treatment on lesion size, sensorimotor and cognitive behavior, and determined the therapeutic window and dose response relationships. Furthermore, the appearance of MSCs at the lesion site in relation to the therapeutic window was examined. Nine-day-old mice were subjected to unilateral carotid artery occlusion and hypoxia. MSCs were administered intranasally at 3, 10 or 17 days after hypoxia-ischemia (HI. Motor, cognitive and histological outcome was investigated. PKH-26 labeled cells were used to localize MSCs in the brain. We identified 0.5 × 10(6 MSCs as the minimal effective dose with a therapeutic window of at least 10 days but less than 17 days post-HI. A single dose was sufficient for a marked beneficial effect. MSCs reach the lesion site within 24 h when given 3 or 10 days after injury. However, no MSCs were detected in the lesion when administered 17 days following HI. We also show for the first time that intranasal MSC treatment after HI improves cognitive function. Improvement of sensorimotor function and histological outcome was maintained until at least 9 weeks post-HI. The capacity of MSCs to reach the lesion site within 24 h after intranasal administration at 10 days but not at 17 days post-HI indicates a therapeutic window of at least 10 days. Our data strongly indicate that intranasal MSC treatment may become a promising non-invasive therapeutic tool to effectively reduce neonatal encephalopathy.

    Traditional Chinese medicine is one of the popular alternative treatments for cancer, mainly enhancing host immune response and reducing adverse effect of chemotherapy. This study first explored traditional Chinese medicine treatment effect on long-term survival of lung cancer patients. This study evaluated whether traditional Chinese medicine combined with conventional cancer treatment improved overall survival of lung cancer patients. We had conducted a retrospective cohort study on 111,564 newly diagnosed lung cancer patients in 2000-2009 from National Health Insurance Program database. A total of 23,803 (21.31%) patients used traditional Chinese medicine for lung cancer care. Eligible participants were followed up until 2011 with a mean follow-up period of 1.96 years (standard deviation 2.55) for non-TCM users and 3.04 years (2.85) for traditional Chinese medicine users. Patients with traditional Chinese medicine utilization were significantly more likely to have a 32% decreased risk of death [hazard ratio = 0.62; 95% confidence interval = 0.61-0.63], compared with patients without traditional Chinese medicine utilization after multivariate adjustment. We also observed a similar significant reduction risk across various subgroups of chronic lung diseases. Qing Zao Jiu Fei Tang was the most effective traditional Chinese medicine agent for mortality reduction both in the entire lung cancer (0.81; 0.72-0.91) and matched populations (0.86; 0.78-0.95). This study demonstrated adjunctive therapy with traditional Chinese medicine may improve overall survival of lung cancer patients. This study also suggested traditional Chinese medicine may be used as an adjunctive therapy for cancer treatment. These observational findings need being validated by future randomized controlled trials to rule out the possibility of effect due to holistic care.

    Objective The cochlear implant (CI) improves quality of life for people who are severely and profoundly deafened, allowing implantees to perceive speech at levels similar to those of individuals with normal hearing. However, patients with CIs generally report a reduced appreciation of music after implantation. We aimed to systematically review the English-language literature for studies evaluating music enjoyment and perception among adult patients with CIs. Data Sources A systematic review of PubMed/MEDLINE, Scopus, Embase, and the Cochrane Library. Review Methods The PRISMA statement was utilized to identify English-language studies reporting music appreciation among adults with CIs. Two independent reviewers performed searches through May 2017. Included studies investigated parameters related to music enjoyment and music perception, including (1) pitch and timbre perception, (2) noise-canceling algorithms, and (3) the presence of dissonant chords, lyrics, or visual cues. Results A total of 508 articles were screened for relevance. Forty-one full-text articles were evaluated, and 18 met final inclusion criteria. Studies used heterogeneous methods of outcome measurement for identifying music appreciation. The outcome measures suggest that rhythm and lyrics are important components of enjoyment. Patients with CIs had difficulty with pitch and timbre perception. Conclusion The heterogeneous outcome measures identified in this systematic review suggest that rhythm and lyrics are important components of enjoyment, while patients with CIs had difficulty with pitch and timbre perception. Because there is no standardized reporting metric for music appreciation among adult patients with CIs, a standardized validated outcome-measuring tool is warranted.

    In previous work, a thermal spray multilayer system consisting of Zirconia (ZrO{sub 2}) and MCrAlY top coat showed promising results regarding the oxidation behavior of the Gamma Titanium Aluminides substrates tested, which encouraged further research activities. Diffusion of substrate material was successfully inhibited by a ceramic Zirconia coating. A building up of a dense and stable oxide layer could be achieved by additional application of an MCrAlY top coat, leading to improved oxidation resistance and thus showing feasibility. In this work the main focus for development was put on enhancing adhesion and lowering residual stresses of the coatings in order to allow long term and cyclic testing without delamination taking place. Being a very brittle material, Gamma Titanium Aluminides require special surface treatment to enable roughening which is crucial for a strong mechanical bond between substrate and coating. Alternatives to conventional grit blasting as a standard preparation method were investigated. These were micro-abrasive blasting and blasting at elevated temperature ({approx}300-550 C) to allow a more ductile behavior. The paper will highlight the implications by means of these measures and will also show the present development status of the multilayer system.

    2009-01-01

    This paper proposes an improved merit order (IMO) combined with an augmented Lagrangian Hopfield network (ALHN) for solving short term hydrothermal scheduling (HTS) with pumped-storage hydro plants. The proposed IMO-ALHN consists of a merit order based on the average production cost of generating units enhanced by heuristic search algorithm for finding unit scheduling and a continuous Hopfield neural network with its energy function based on augmented Lagrangian relaxation for solving constrained economic dispatch (CED). The proposed method is applied to solve the HTS problem in five stages including thermal, hydro and pumped-storage unit commitment by IMO and heuristic search, constraint violations repairing by heuristic search and CED by ALHN. The proposed method is tested on the 24-bus IEEE RTS with 32 units including 4 fuel-constrained, 4-hydro, and 2 pumped-storage units scheduled over a 24-h period. Test results indicate that the proposed IMO-ALHN is efficient for hydrothermal systems with various constraints.

    The potential for savings in the nuclear fuel cycle costs is discussed from the point of view of a single utility. The analysis is concentrated on the existing and near-term economic incentives for improved fuel utilization, and the context is that of a small country without domestic fuel cycle services. In the uranium fuel cycle the extended burnup produces savings in the uranium feed as well as in the fuel fabrication and waste management requirements. The front-end fuel cycle cost impact is evaluated for BWRs. In the back-end part the situation is more specific of the concrete back-end solution. Estimates for savings in the cost of direct disposal of spent fuel are presented for a Finnish case. The economics of recycle is reviewed from a recent study on the use of MOX fuel in the Finnish BWRs. The results from a comparison with once-through alternative show that spent fuel reprocessing with consequent recycle of uranium and plutonium would be economically justified only with very high uranium prices.

    Full Text Available This study was conducted to examine the effects of antibiotic (5000 units of penicillin on sperm quality of Persian sturgeon, Acipenser persicus during 9 days in vitro storage of milt. For this purpose, the milt samples were stored in the presence and absence of 5000 units of penicillin. Freshwater was used as sperm activator. The milt samples were stored at 4°C and the motility indices were measured 0, 3, 6 and 9 days after storage. The sperm duration and percentage of sperm motility decreased after 6 days of storage both in the presence and absence of antibiotic, although this decrease was more significant in the absence of antibiotic. After 9 days of storage, the lowest values of sperm motility indices was recorded for antibiotic receiving milt samples while no motile spermatozoa observed for antibiotic-free milt samples. In conclusion, our results demonstrated that 5000 units of penicillin improve the Persian sturgeon milt quality during short-term storage.

    The Responsive Leadership Intervention (RLI) is a multi-faceted intervention. We evaluated the influence of the RLI on i) responsive leadership practices by team leaders; ii) health care aides' (HCAs) self-determination; iii) HCAs' perceived ability to provide individualized care. A quasi-experimental repeated measures non-equivalent control group design was used to assess participant outcomes in four long-term care facilities (two control, two intervention) across four time periods. Change from baseline to 1-month post-intervention was greater in the intervention group than control group for Individualized Care (IC) (p = 0.001), but not for Self Determination (p = 0.26). Perceived levels of responsive leadership was greater following the intervention among participants with baseline measures that were less than the median (p = 0.007), but not if greater. At 3-months post-intervention, the intervention group retained 32% of the difference from control in IC, and 49% of the difference from control in responsive leadership; at 6-months post-intervention, 35% and 28%, respectively. The RLI is a feasible method for improving responsive leadership practices and individualized care. Copyright © 2017 Elsevier Inc. All rights reserved.

    2017-12-01

    Full Text Available The Ecovat is a seasonal thermal storage solution consisting of a large underground water tank divided into a number of virtual segments that can be individually charged and discharged. The goal of the Ecovat is to supply heat demand to a neighborhood throughout the entire year. In this work, we extend an integer linear programming model to describe the charging and discharging of such an Ecovat buffer by adding a long-term (yearly planning step to the model. We compare the results from the model using this extension to previously obtained results and show significant improvements when looking at the combination of costs and the energy content of the buffer at the end of the optimization. Furthermore, we show that the model is very robust against prediction errors. For this, we compare two different cases: one case in which we assume perfect predictions are available and one case in which we assume no predictions are available. The largest observed difference in costs between these two cases is less than 2%.

  9. Incorporating geostrophic wind information for improved space–time short-term wind speed forecasting

    2014-09-01

    Accurate short-term wind speed forecasting is needed for the rapid development and efficient operation of wind energy resources. This is, however, a very challenging problem. Although on the large scale, the wind speed is related to atmospheric pressure, temperature, and other meteorological variables, no improvement in forecasting accuracy was found by incorporating air pressure and temperature directly into an advanced space-time statistical forecasting model, the trigonometric direction diurnal (TDD) model. This paper proposes to incorporate the geostrophic wind as a new predictor in the TDD model. The geostrophic wind captures the physical relationship between wind and pressure through the observed approximate balance between the pressure gradient force and the Coriolis acceleration due to the Earth’s rotation. Based on our numerical experiments with data from West Texas, our new method produces more accurate forecasts than does the TDD model using air pressure and temperature for 1to 6-hour-ahead forecasts based on three different evaluation criteria. Furthermore, forecasting errors can be further reduced by using moving average hourly wind speeds to fit the diurnal pattern. For example, our new method obtains between 13.9% and 22.4% overall mean absolute error reduction relative to persistence in 2-hour-ahead forecasts, and between 5.3% and 8.2% reduction relative to the best previous space-time methods in this setting.

    Bone cement is used for ossicular chain repair and revision stapes surgery. Its efficient use requires cautious removal of mucosa from the ossicles. This paper reports a technique for easy, fast and safe removal of this mucosa prior to cement application. It consists of the application of monopolar electrocoagulation on the ossicles prior to bone cement application. The outcomes of six cases of revision stapes surgery and seven cases of partial ossiculoplasty, conducted between 2007 and 2012 using this new technique, were evaluated. Intra-operative reports and audiometric data were collected. During the last assessment, reconstruction using bone cement resulted in mean post-operative air-bone gaps of 4.1 ± 6.5 dB in revision stapes surgery cases and 5.7 ± 5.5 dB in partial ossiculoplasty cases, reflecting a significant hearing improvement (p = 0.03). No complications were observed. Electrocoagulation allows the removal of mucosa from the ossicles in an easy, fast and safe manner, enabling the use of bone cement for ossicular chain reconstruction.

    The physical housing environment is important to facilitate activities of daily living (ADL) for older people. A hindering environment may lead to ADL dependence and thus increase the need for home services, which is individually restricting and a growing societal burden. This study presents simulations of policy changes with regard to housing accessibility that estimates the potential impact specifically on instrumental activities of daily living (I-ADL), usage of home services, and related costs. The models integrate empirical data to test the hypothesis that a policy providing funding to remove the five most severe environmental barriers in the homes of older people who are at risk of developing dependence in I-ADL, can maintain independence and reduce the need for home services. In addition to official statistics from state agencies in Sweden and Germany, we utilized published results from the ENABLE-AGE and other scientific studies to generate the simulations. The simulations predicted that new policies that remove potentially hindering housing features would improve I-ADL performance among older people and reduce the need for home services. Our findings suggest that a policy change can contribute to positive effects with regard to I-ADL independence among older people and to a reduction of societal burden.

    Connectedness to nature (i.e., an affective and experiential connection to nature) is known to have a positive effect on psychological well-being, but its specific associations with body image have not been fully examined. To attend to this oversight, we conducted a preliminary investigation of associations between connectedness to nature and body appreciation. A total of 380 British adults completed measures of connectedness to nature, body appreciation, and self-esteem. Bivariate correlations revealed significant positive associations between all variables in women. In men, body appreciation was significantly correlated with self-esteem, but not connectedness to nature. Mediation analysis showed that, in women, self-esteem fully mediated the relationship between connectedness to nature and body appreciation. In men, body appreciation was significantly associated with self-esteem, but not connectedness to nature. These results point to a potential route for improving body image among women through connectedness to nature and self-esteem, but further research is necessary. Copyright © 2015 Elsevier Ltd.

    2018-07-01

    In industrial countries home care services for elderly people living in the community are growing rapidly. Home care nursing is intensive and the nurses often suffer from musculoskeletal pain. Time pressure and job control are job-related factors linked to the risk of experiencing lower back pain (LBP) and LBP-related work impairment. This survey investigated whether work-family conflict (WFC), emotional dissonance and being appreciated at work have incremental predictive value. Responses were obtained from 125 home care nurses (63% response rate). Multiple linear regression showed that emotional dissonance and being appreciated at work predicted LBP intensity and LBP-related disability independently of time pressure and job control. WFC was not a predictor of LBP-related disability in multiple regression analyses despite a zero-order correlation with it. Redesigning the working pattern of home care nurses to reduce the emotional demands and improve appreciation of their work might reduce the incidence of LBP in this group.

    Patients with advanced metastatic melanoma are often confronted with little prospect of medium- to longer-term survival by any currently available therapeutic means. However, most clinicians are aware of exceptional cases where survival defies the notion of futility. Prolonged survival from immunotherapies, including interleukin-2, vaccines and antibodies to cytotoxic lymphocyte antigen-4, and programmed death-1 receptor inhibitory monoclonal antibody, implies a role for immune system modulation. We aimed to identify cases where exceptional survival from advanced melanoma occurred prior to recent novel therapies to facilitate better understanding of this phenomenon. Cases of long-term survival of ≥3 years’ duration (from diagnosis of metastatic disease) were identified from the database of one clinician; these cases were treated before the availability of newer immunotherapies, and they were documented and examined. A literature search for reported outcome measures from published studies using older and recent therapies for advanced melanoma was conducted to enable the comparison of data. Eighteen cases were identified that identified survival of ≥3 years’ duration from metastatic disease (12 American Joint Committee on Cancer [AJCC] Stage IV cases; six AJCC III cases) diagnosis. These were assessed and reported to detail the clinical course. Standard clinical prognostication methods predicted high risk of early mortality in those patients. No identifiable differences could be detected between these and other patients with similar patterns of disease. At evaluation, 17 patients (94%) had survived ≥5 years, and eleven patients (61%) had survived ≥10 years (range: 3–15 years). The median survival duration with metastatic disease was 11 years; 15 remained alive and three had died. Published studies of melanoma therapies were tabled for comparison. The fact that 18 cases of exceptional survival in advanced melanoma were identified is remarkable in itself

    Abstract The Immune Epitope Database (IEDB), at www.iedb.org, has the mission to make published experimental data relating to the recognition of immune epitopes easily available to the scientific public. By presenting curated data in a searchable database, we have liberated it from the tables and figures of journal articles, making it more accessible and usable by immunologists. Recently, the principles of Findability, Accessibility, Interoperability and Reusability have been formulated as goals that data repositories should meet to enhance the usefulness of their data holdings. We here examine how the IEDB complies with these principles and identify broad areas of success, but also areas for improvement. We describe short-term improvements to the IEDB that are being implemented now, as well as a long-term vision of true ‘machine-actionable interoperability’, which we believe will require community agreement on standardization of knowledge representation that can be built on top of the shared use of ontologies.

    In India, as in some other neighboring Asian countries, students and teachers are generally unaware of the differences in the learning styles among learners, which can handicap students with learning styles alien to the common teaching/learning modality within the institution. This study aims to find out whether making students aware of their learning styles and then using the Appreciative Inquiry approach to help them discover learning strategies that worked for them and others with similar learning styles within the institution made them perceive that this experience improved their learning and performance in exams. The visual, auditory, read-write, and kinesthetic (VARK) inventory of learning styles questionnaire was administered to all 100 first-year medical students of the Father Muller's Medical College in Mangalore India to make them aware of their individual learning styles. An Appreciate Inquiry intervention was administered to 62 student volunteers who were counseled about the different learning styles and their adaptive strategies. Pre and post intervention change in student's perception about usefulness of knowing learning styles on their learning, learning behavior, and performance in examinations was collected from the students using a prevalidated questionnaire. Post intervention mean scores showed a significant change (P learning style and discovering strategies that worked within the institutional environment. There was agreement among students that the intervention helped them become more confident in learning (84%), facilitating learning in general (100%), and in understanding concepts (100%). However, only 29% of the students agreed that the intervention has brought about their capability improvement in application of learning and 31% felt it improved their performance in exams. Appreciate Inquiry was perceived as useful in helping students discover learning strategies that work for different individual learning styles and sharing them within

    This thesis aims to integrate components of an economic model of the behaviors of households in a technological model of French residential sector energy consumption dynamics and to analyze the consequences of this integration on the results of long-term residential energy consumption simulations (2030-2050). The results of this work highlight significant differences between the actual household space heating energy consumptions and those estimated by engineering models. These differences are largely due to the elasticity of thermal comfort demand to thermal comfort price. Our improved model makes it possible to conjointly integrate the concepts of price elasticity and rebound effect (the increase in energy service level following an improvement in energy performance of the equipment providing the service) in a daily behavior model. Regarding space heating consumption, the consequences of this behavioral adaptation - combined with some technical defects - are a significant reduction of the technical and behavioral energy saving potentials (while effective daily use of energy is generally lower than predicted by engineering models) at a national level. This implies that mid and long-term national energy policy targets (a 38% drop in primary energy consumption by 2020 and a reduction in greenhouse gas emissions by a factor of 4 by 2050 compared to the 1990 level) will be harder to reach than previously expected for the residential sector. These results also imply that a strong reduction in carbon emissions cannot be achieved solely through the diffusion of efficient technologies and energy conservation behavior but also requires to significantly lower the average carbon content of residential space heating energy through the generalized use of wood energy. The second issue addressed in this thesis is the influence of the resolution of a techno-economic model (i.e. its ability to represent the various values that a variable can have within the modeled system) on its

    Full Text Available Abstract Background Biomedical named entity recognition (Bio-NER is a challenging problem because, in general, biomedical named entities of the same category (e.g., proteins and genes do not follow one standard nomenclature. They have many irregularities and sometimes appear in ambiguous contexts. In recent years, machine-learning (ML approaches have become increasingly common and now represent the cutting edge of Bio-NER technology. This paper addresses three problems faced by ML-based Bio-NER systems. First, most ML approaches usually employ singleton features that comprise one linguistic property (e.g., the current word is capitalized and at least one class tag (e.g., B-protein, the beginning of a protein name. However, such features may be insufficient in cases where multiple properties must be considered. Adding conjunction features that contain multiple properties can be beneficial, but it would be infeasible to include all conjunction features in an NER model since memory resources are limited and some features are ineffective. To resolve the problem, we use a sequential forward search algorithm to select an effective set of features. Second, variations in the numerical parts of biomedical terms (e.g., "2" in the biomedical term IL2 cause data sparseness and generate many redundant features. In this case, we apply numerical normalization, which solves the problem by replacing all numerals in a term with one representative numeral to help classify named entities. Third, the assignment of NE tags does not depend solely on the target word's closest neighbors, but may depend on words outside the context window (e.g., a context window of five consists of the current word plus two preceding and two subsequent words. We use global patterns generated by the Smith-Waterman local alignment algorithm to identify such structures and modify the results of our ML-based tagger.

    Exposure to volatile anesthetics has been reported to cause temporary or sustained impairments in learning and memory in pre-clinical studies. The selective antagonists of the histamine H3 receptors (H3R) are considered to be a promising group of novel therapeutic agents for the treatment of cognitive disorders. The aim of this study was to evaluate the effect of H3R antagonist ciproxifan on isoflurane-induced deficits in an object recognition task. Adult C57BL/6 J mice were exposed to isoflurane (1.3 %) or vehicle gas for 2 h. The object recognition tests were carried at 24 h or 7 days after exposure to anesthesia to exploit the tendency of mice to prefer exploring novel objects in an environment when a familiar object is also present. During the training phase, two identical objects were placed in two defined sites of the chamber. During the test phase, performed 1 or 24 h after the training phase, one of the objects was replaced by a new object with a different shape. The time spent exploring each object was recorded. A robust deficit in object recognition memory occurred 1 day after exposure to isoflurane anesthesia. Isoflurane-treated mice spent significantly less time exploring a novel object at 1 h but not at 24 h after the training phase. The deficit in short-term memory was reversed by the administration of ciproxifan 30 min before behavioral training. Isoflurane exposure induces reversible deficits in object recognition memory. Ciproxifan appears to be a potential therapeutic agent for improving post-anesthesia cognitive memory performance.

    The respiratory tract is a major target of exposure to air pollutants, and respiratory diseases are associated with both short- and long-term exposures. We hypothesized that improved air quality in North Carolina was associated with reduced rates of death from respiratory diseases in local populations. We analyzed the trends of emphysema, asthma, and pneumonia mortality and changes of the levels of ozone, sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and particulate matters (PM2.5 and PM10) using monthly data measurements from air-monitoring stations in North Carolina in 1993-2010. The log-linear model was used to evaluate associations between air-pollutant levels and age-adjusted death rates (per 100,000 of population) calculated for 5-year age-groups and for standard 2000 North Carolina population. The studied associations were adjusted by age group-specific smoking prevalence and seasonal fluctuations of disease-specific respiratory deaths. Decline in emphysema deaths was associated with decreasing levels of SO2 and CO in the air, decline in asthma deaths-with lower SO2, CO, and PM10 levels, and decline in pneumonia deaths-with lower levels of SO2. Sensitivity analyses were performed to study potential effects of the change from International Classification of Diseases (ICD)-9 to ICD-10 codes, the effects of air pollutants on mortality during summer and winter, the impact of approach when only the underlying causes of deaths were used, and when mortality and air-quality data were analyzed on the county level. In each case, the results of sensitivity analyses demonstrated stability. The importance of analysis of pneumonia as an underlying cause of death was also highlighted. Significant associations were observed between decreasing death rates of emphysema, asthma, and pneumonia and decreases in levels of ambient air pollutants in North Carolina.

    The visual system has developed to transform an undifferentiated and continuous flow of information into discrete and manageable representations, and this ability rests primarily on the uninterrupted nature of the input. Here we explore the impact of altering how visual information is accumulated over time by assessing how intermittent vision influences memory retention. Previous work has shown that intermittent, or stroboscopic, visual training (i.e., practicing while only experiencing snapshots of vision) can enhance visual-motor control and visual cognition, yet many questions remain unanswered about the mechanisms that are altered. In the present study, we used a partial-report memory paradigm to assess the possible changes in visual memory following training under stroboscopic conditions. In Experiment 1, the memory task was completed before and immediately after a training phase, wherein participants engaged in physical activities (e.g., playing catch) while wearing either specialized stroboscopic eyewear or transparent control eyewear. In Experiment 2, an additional group of participants underwent the same stroboscopic protocol but were delayed 24 h between training and assessment, so as to measure retention. In comparison to the control group, both stroboscopic groups (immediate and delayed retest) revealed enhanced retention of information in short-term memory, leading to better recall at longer stimulus-to-cue delays (640-2,560 ms). These results demonstrate that training under stroboscopic conditions has the capacity to enhance some aspects of visual memory, that these faculties generalize beyond the specific tasks that were trained, and that trained improvements can be maintained for at least a day.

    Norepinephrine reuptake inhibitors (NRIs) acutely increase norepinephrine (NE) levels, but therapeutic antidepressant activity is only observed after weeks of treatment because central NE levels progressively increase during continued drug exposure. Similarly, while NRIs acutely increase blood pressure (BP) and heart rate (HR) due to enhanced sympathetic neurotransmission, chronic treatment changes the responsiveness of the central noradrenergic system and suppresses these effects via autonomic regulation. To better understand the relationship between NE increases and cardiovascular safety, we investigated acute and chronic effects of the NRI reboxetine on central NE release and on BP and HR and electrical alternans, a measure of arrhythmia liability, in guinea pigs. NE release was assessed by microdialysis in medial prefrontal cortex (mPFC) and hypothalamic paraventricular nucleus (PVN); BP and HR were measured by telemetry. Animals were treated for 28 days with 15 mg/kg/day of reboxetine or vehicle via an osmotic minipump and then challenged with acute intravenous doses of reboxetine. Animals chronically treated with reboxetine had 2-fold higher extracellular basal NE levels in mPFC and PVN compared to basal levels after chronic vehicle treatment. BP was significantly increased after the first day of treatment, and gradually returned to vehicle levels by day 21. These data indicate that chronic NRI treatment may lead to an increase in central NE levels and a concomitant reduction in BP based on exposure–response curves compared to vehicle treatment, suggesting a larger separation between preclinical estimates of efficacy vs. safety compared to acute NRI treatment. -- Highlights: ► Acute RBX produces blood pressure increases acutely that decrease with chronic RBX ► Chronic RBX increases brain NE levels, a preclinical surrogate of improved efficacy ► Short-term screening of NRI often underestimates the chronic therapeutic index ► Chronic cardiovascular

    Many chemistry educators have adopted the process-oriented guided instructional learning (POGIL) pedagogy. However, it is not clear which aspects of POGIL are the most important in terms of actual learning. We compared 354 first-year undergraduate psychology students' learning in physiological psychology using four teaching methods: control, POGIL, POGIL without reporting [no report out (NRO)], and POGIL run by untrained graduate students [new facilitator (NF)]. Student activities were identical across POGIL variations and highly similar for control. Participants' knowledge was evaluated before (pretest), immediately after (posttest), and 2 wk later (followup). Control and POGIL groups showed no improvement at posttest, whereas NRO and NF groups both recalled more material than at pretest (P = 0.002 and P < 0.0005, respectively). In a surprise test 2 wk later, control (P < 0.0005), NRO (P = 0.03), and NF (P < 0.0005) groups recalled less than at posttest. The POGIL group showed the smallest drop in knowledge (P = 0.05). Importantly, the control group's knowledge was below pretest levels (P < 0.0005), whereas the POGIL, NRO, and NF groups' knowledge was not. Self-assessment of knowledge was consistent across groups at pretest, but POGIL participants had the lowest confidence at posttest and 2 wk later. At followup, the control, NRO, and NF groups showed greater confidence in their knowledge than the POGIL group (P = 0.03, P = 0.002, and P = 0.004, respectively). POGIL and its variations appear to consolidate existing knowledge against memory decay even when student confidence does not match performance.

    The Midwestern United States, a region that produces one-third of maize and one-quarter of soybeans globally, is projected to experience increasing rainfall variability with future climate change. One approach to mitigate climate impacts is to utilize crop and soil management practices that enhance soil water storage, reducing the risks of flooding and runoff as well as drought-induced crop water stress. While some research indicates that a winter cover crop in a maize-soybean rotation increases soil water, producers continue to be concerned that water use by cover crops will reduce water for a following cash crop. We analyzed continuous in-field soil moisture measurements over from 2008-2014 at a Central Iowa research site that has included a winter rye cover crop in a maize-soybean rotation for thirteen years. This period of study included years in the top third of wettest years on record (2008, 2010, 2014) as well as years in the bottom third of driest years (2012, 2013). We found the cover crop treatment to have significantly higher soil water storage from 2012-2014 when compared to the no cover crop treatment and in most years greater soil water content later in the growing season when a cover crop was present. We further found that the winter rye cover crop significantly increased the field capacity water content and plant available water compared to the no cover crop treatment. Finally, in 2012 and 2013, we measured maize and soybean biomass every 2-3 weeks and did not see treatment differences in crop growth, leaf area or nitrogen uptake. Final crop yields were not statistically different between the cover and no cover crop treatment in any of the years of this analysis. This research indicates that the long-term use of a winter rye cover crop can improve soil water dynamics without sacrificing cash crop growth.

Focusing on his use of notions of narrative and counterstories I explore the politics of experience in education looking at how he uses narrative and story, the politics entailed in the polyvocal evidence he presents and the significance of the ethnographic context for his account. After a discussion of these three significant conceptual insights I conclude with a return to his account and his somewhat diffident reflections about the project he reports on.

    A derived addition to the BGK collision term,is improved and expressed in simple form. The collision frequency for scattering depends anisotropically on the velocity vector. The improved macroscopic equation of momentum flow is applied to the Hall effect, the cold plasma dispersion relation and the cyclotron resonance. The Hall coefficient which is constant in the case of the BGK collision term now depends on the magnetic field. It is also shown that, compared with the almost symmetric classical curves of cyclotron resonance, the new curves are considerably asymmetric and their half-widths are about 3/2 times the classical ones.

    Research shows that active support provision is associated with greater well-being for spouses of individuals with chronic conditions. However, not all instances of support may be equally beneficial for spouses' well-being. The theory of communal responsiveness suggests that because spouses' well-being is interdependent, spouses benefit most from providing support when they believe their support increases their partner's happiness and is appreciated. Two studies tested this hypothesis. Study 1 was a 7-day ecological momentary assessment (EMA) study of 73 spouses of persons with dementia (74%) and other conditions. In Study 1, spouses self-reported active help, perceptions of how happy the help made the partner and how much the help improved the partner's well-being, and spouses' positive and negative affect at EMA time points. Study 2 was a 7-day daily assessment study of 43 spouses of persons with chronic pain in which spouses reported their emotional support provision, perceived partner appreciation, and their own physical symptoms. Study 1 showed that active help was associated with more positive affect for spouses when they perceived the help increased their partner's happiness and improved their partner's well-being. Study 2 showed that emotional support provision was associated with fewer spouse reported physical symptoms when perceptions of partner appreciation were high. Results suggest that interventions for spouses of individuals with chronic conditions take into account spouses' perceptions of their partners' positive emotional responses. Highlighting the positive consequences of helping may increase spouses' well-being. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  1. Tiagabine improves hippocampal long-term depression in rat pups subjected to prenatal inflammation.

    Directory of Open Access Journals (Sweden)

    Aline Rideau Batista Novais

    Full Text Available Maternal inflammation during pregnancy is associated with the later development of cognitive and behavioral impairment in the offspring, reminiscent of the traits of schizophrenia or autism spectrum disorders. Hippocampal long-term potentiation and long-term depression of glutamatergic synapses are respectively involved in memory formation and consolidation. In male rats, maternal inflammation with lipopolysaccharide (LPS led to a premature loss of long-term depression, occurring between 12 and 25 postnatal days instead of after the first postnatal month, and aberrant occurrence of long-term potentiation. We hypothesized this would be related to GABAergic system impairment. Sprague Dawley rats received either LPS or isotonic saline ip on gestational day 19. Male offspring's hippocampus was studied between 12 and 25 postnatal days. Morphological and functional analyses demonstrated that prenatal LPS triggered a deficit of hippocampal GABAergic interneurons, associated with presynaptic GABAergic transmission deficiency in male offspring. Increasing ambient GABA by impairing GABA reuptake with tiagabine did not interact with the low frequency-induced long-term depression in control animals but fully prevented its impairment in male offspring of LPS-challenged dams. Tiagabine furthermore prevented the aberrant occurrence of paired-pulse triggered long-term potentiation in these rats. Deficiency in GABA seems to be central to the dysregulation of synaptic plasticity observed in juvenile in utero LPS-challenged rats. Modulating GABAergic tone may be a possible therapeutic strategy at this developmental stage.

    Bats are diverse and ecologically important, but are also subject to a suite of severe threats. Evidence for localized bat mortality from these threats is well-documented in some cases, but long-term changes in regional populations of bats remain poorly understood. Bat hibernation surveys provide an opportunity to improve understanding, but analysis is complicated by...

  5. Appreciation and implementation of the Krachtvoer healthy diet promotion programme for 12- to 14- year-old students of prevocational schools

    Science.gov (United States)

    2011-01-01

    Background Krachtvoer is a school-based healthy diet programme, developed in 2001 and revised in 2007 to meet the needs of particular segments of the target population as well as a wider target group. The main aims of the present process evaluation of the revised programme were to examine student and teacher appreciation of the programme, completeness of and adherence to its implementation, and relations between appreciation and completeness of implementation. Methods Data were collected among 22 teachers and 1117 students of 13 schools, using student evaluation forms, teacher logbooks, telephone interviews, and classroom observations. Results Results indicate favourable levels of teacher and student appreciation for the programme in general and the revised elements. Girls, first-year students and students with more favourable dietary intakes particularly appreciated individual programme elements. Levels of completeness of implementation were high, but several teachers did not adhere to the intended implementation period. Some moderately strong relations were found between teacher appreciation and completeness of implementation scores. Conclusion We conclude that the revisions have resulted in a programme that was appreciated well, also by the extended target group, and was implemented with a high degree of completeness. Teacher appreciation proved potentially important for completeness of implementation. We identified several aspects requiring improvement, indicating the importance of continued programme updates and repeated evaluation. PMID:22151954

    Similarity-based retrieval of Electronic Health Records (EHRs) from large clinical information systems provides physicians the evidence support in making diagnoses or referring examinations for the suspected cases. Clinical Terms in EHRs represent high-level conceptual information and the similarity measure established based on these terms reflects the chance of inter-patient disease co-occurrence. The assumption that clinical terms are equally relevant to a disease is unrealistic, reducing the prediction accuracy. Here we propose a term weighting approach supported by PubMed search engine to address this issue. We collected and studied 112 abdominal computed tomography imaging examination reports from four hospitals in Hong Kong. Clinical terms, which are the image findings related to hepatocellular carcinoma (HCC), were extracted from the reports. Through two systematic PubMed search methods, the generic and specific term weightings were established by estimating the conditional probabilities of clinical terms given HCC. Each report was characterized by an ontological feature vector and there were totally 6216 vector pairs. We optimized the modified direction cosine (mDC) with respect to a regularization constant embedded into the feature vector. Equal, generic and specific term weighting approaches were applied to measure the similarity of each pair and their performances for predicting inter-patient co-occurrence of HCC diagnoses were compared by using Receiver Operating Characteristics (ROC) analysis. The Areas under the curves (AUROCs) of similarity scores based on equal, generic and specific term weighting approaches were 0.735, 0.728 and 0.743 respectively (p PubMed. Our findings suggest that the optimized similarity measure with specific term weighting to EHRs can improve significantly the accuracy for predicting the inter-patient co-occurrence of diagnosis when compared with equal and generic term weighting approaches.

    Early change is commonly assessed for manual therapy interventions and has been used to determine treatment appropriateness. However, current studies have only explored the relationship of between or within-session changes and short-/medium-term outcomes. The goal of this study was to determine whether pain changes after two weeks of pragmatic manual therapy could predict those participants with chronic low back pain who demonstrate continued improvements at 6-month follow-up. This study was a retrospective observational design. Univariate logistic regression analyses were performed using a 33% and a 50% pain change to predict improvement. Those who experienced a ≥33% pain reduction by 2 weeks had 6.98 (95% CI = 1.29, 37.53) times higher odds of 50% improvement on the GRoC and 4.74 (95% CI = 1.31, 17.17) times higher odds of 50% improvement on the ODI (at 6 months). Subjects who reported a ≥50% pain reduction at 2 weeks had 5.98 (95% CI = 1.56, 22.88) times higher odds of a 50% improvement in the GRoC and 3.99 (95% CI = 1.23, 12.88) times higher odds of a 50% improvement in the ODI (at 6 months). Future studies may investigate whether a change in plan of care is beneficial for patients who are not showing early improvement predictive of a good long-term outcome.

    2013-04-01

    Art appreciation often involves contemplation beyond immediate perceptual experience. However, there are challenges to incorporating such processes into a comprehensive theory of art appreciation. Can appreciation be captured in the responses to individual artworks? Can all forms of contemplation be defined? What properties of artworks trigger contemplation? We argue that such questions are fundamental to a psycho-historical framework for the science of art appreciation, and we suggest research that may assist in refining this framework.

    Full Text Available Abstract Background As in most fields of health care, societal and political changes encourage suppliers of long-term care to put their clients at the center of care and service provision and become more responsive towards client needs and requirements. However, the diverse, multiple and dynamic nature of demand for long-term care complicates the movement towards demand-based care provision. This paper aims to advance long-term care practice and, to that end, examines the application of modularity. This concept is recognized in a wide range of product and service settings for its ability to design demand-based products and processes. Methods Starting from the basic dimensions of modularity, we use qualitative research to explore the use and application of modularity principles in the current working practices and processes of four organizations in the field of long-term care for the elderly. In-depth semi-structured interviews were conducted with 38 key informants and triangulated with document research and observation. Data was analyzed thematically by means of coding and subsequent exploration of patterns. Data analysis was facilitated by qualitative analysis software. Results Our data suggest that a modular setup of supply is employed in the arrangement of care and service supply and assists providers of long-term care in providing their clients with choice options and variation. In addition, modularization of the needs assessment and package specification process allows the case organizations to manage client involvement but still provide customized packages of care and services. Conclusion The adequate setup of an organization's supply and its specification phase activities are indispensible for long-term care providers who aim to do better in terms of quality and efficiency. Moreover, long-term care providers could benefit from joint provision of care and services by means of modular working teams. Based upon our findings, we are able to

    If grout and/or concrete barriers and containments are considered for long-term (500 yrs to 100,000 ) waste disposal, then long-term degradation of grout/cement materials (and others) need to be studied. Long-term degradations of a cementitious grout monolith (15.4mW x 10.4mH x 37.6mL) and its containment concrete shell and asphalt shell (each 1-m thick) were analyzed. The main degradation process of the concrete shell was believed to be fractures due to construction joints, shrinkage, thermal stress, settlement, and seismic events. A scenario with fractures was modeled (flow and transport model) for long-term risk performance (out to a million yrs). Even though the concrete/grout is expected to fracture, the concrete/grout chemistry, which has high Ph value, is very beneficial in causing calcite deposits from calcium in the water precipitating in the fractures. These calcite deposits will tend to plug the fracture and keep water from entering. The effectiveness of such plugging needs to be studied more. It's possible that the plugged fractures are more impermeable than the original concrete/grout. The long-term performance of concrete/grout barriers will be determined by its chemistry, not its mechanical properties

    Chronic inflammation has been proposed as one of the main molecular mechanisms of aging and age-related diseases. Although evidence in humans is limited, short-term calorie restriction (CR) has been shown to have anti-inflammatory effects in aged experimental animals. We reported on the long-term treatment of daumone, a synthetic pheromone secreted by Caenorhabditis elegans in an energy deficient environment, extends the life-span and attenuates liver injury in aged mice. The present study examined whether late onset short-term treatment of daumone exerts anti-inflammatory effects in the livers of aged mice. Daumone was administered orally at doses of 2 or 20 mg/kg/day for 5 weeks to 24-month-old male C57BL/6J mice. Increased liver macrophage infiltration and gene expression of proinflammatory cytokines in aged mice were significantly attenuated by daumone treatment, suggesting that short-term oral administration of daumone may have hepatoprotective effects. Daumone also dose-dependently suppressed tumor necrosis factor-α (TNF-α)-induced nuclear factor-κB (NF-κB) phosphorylation in HepG2 cells. The present data demonstrated that short-term treatment of daumone has anti-inflammatory effects in aged mouse livers possibly through suppression of NF-κB signaling and suggest that daumone may become a lead compound targeting aging and age-associated diseases.

    Purpose: The purpose of this study was to evaluate the efficacy of art therapy to control fatigue in cancer patients during course of radiotherapy and its impact on quality of life (QoL). Materials and Methods: Fifty cancer patients receiving radiotherapy received weekly art therapy sessions using famous painting appreciation. Fatigue and QoL were assessed using the Brief Fatigue Inventory (BFI) Scale and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) at baseline before starting radiotherapy, every week for 4 weeks during radiotherapy, and at the end of radiotherapy. Mean changes of scores over time were analyzed using a generalized linear mixed model. Results: Of the 50 patients, 34 (68%) participated in 4 sessions of art therapy. Generalized linear mixed models testing for the effect of time on mean score changes showed no significant changes in scores from baseline for the BFI and FACIT-F. The mean BFI score and FACIT-F total score changed from 3.1 to 2.7 and from 110.7 to 109.2, respectively. Art therapy based on the appreciation of famous paintings led to increases in self-esteem by increasing self-realization and forming social relationships. Conclusion: Fatigue and QoL in cancer patients with art therapy do not deteriorate during a period of radiotherapy. Despite the single-arm small number of participants and pilot design, this study provides a strong initial demonstration that art therapy of appreciation for famous painting is worthy of further study for fatigue and QoL improvement. Further, it can play an important role in routine practice in cancer patients during radiotherapy. PMID:27306778

    2014-01-01

    Highlights: • A detailed data processing will make more accurate results prediction. • Taking a full account of more load factors to improve the prediction precision. • Improved BP network obtains higher learning convergence. • Genetic algorithm optimized by chaotic cat map enhances the global search ability. • The combined GA–BP model improved by modified additional momentum factor is superior to others. - Abstract: This paper proposes an appropriate combinational approach which is based on improved BP neural network for short-term gas load forecasting, and the network is optimized by the real-coded genetic algorithm. Firstly, several kinds of modifications are carried out on the standard neural network to accelerate the convergence speed of network, including improved additional momentum factor, improved self-adaptive learning rate and improved momentum and self-adaptive learning rate. Then, it is available to use the global search capability of optimized genetic algorithm to determine the initial weights and thresholds of BP neural network to avoid being trapped in local minima. The ability of GA is enhanced by cat chaotic mapping. In light of the characteristic of natural gas load for Shanghai, a series of data preprocessing methods are adopted and more comprehensive load factors are taken into account to improve the prediction accuracy. Such improvements facilitate forecasting efficiency and exert maximum performance of the model. As a result, the integration model improved by modified additional momentum factor gets more ideal solutions for short-term gas load forecasting, through analyses and comparisons of the above several different combinational algorithms

    Rhetorical theory suggests that rhythmic and metrical features of language substantially contribute to persuading, moving, and pleasing an audience. A potential explanation of these effects is offered by "cognitive fluency theory," which stipulates that recurring patterns (e.g., meter) enhance perceptual fluency and can lead to greater aesthetic appreciation. In this article, we explore these two assertions by investigating the effects of meter and rhyme in the reception of poetry by means of event-related brain potentials (ERPs). Participants listened to four versions of lyrical stanzas that varied in terms of meter and rhyme, and rated the stanzas for rhythmicity and aesthetic liking. The behavioral and ERP results were in accord with enhanced liking and rhythmicity ratings for metered and rhyming stanzas. The metered and rhyming stanzas elicited smaller N400/P600 ERP responses than their nonmetered, nonrhyming, or nonmetered and nonrhyming counterparts. In addition, the N400 and P600 effects for the lyrical stanzas correlated with aesthetic liking effects (metered-nonmetered), implying that modulation of the N400 and P600 has a direct bearing on the aesthetic appreciation of lyrical stanzas. We suggest that these effects are indicative of perceptual-fluency-enhanced aesthetic liking, as postulated by cognitive fluency theory.

    Full Text Available People with long-term conditions are intensive users of health services as well as being long term users of social care and community services. In the UK, the Department of Health has suggested that the development of a more inclusive approach to services could furnish benefits to people with long-term conditions and financial savings for service providers. Researchers with a varied set of expertise and experience (users of neuro-rehabilitation services, staff working in services, people working with third sector agencies and university academics adopted a participatory research approach to work together to explore what inclusion might look and feel like for people who are long term users of health services. The element of critique and mutual challenge, developed within the research process, disturbed current presentations of inclusion and inclusive practice. It revealed that the more usually expected components of inclusion (trust, respect and shared responsibility whilst necessary for inclusive practice, are not necessarily sufficient. Inclusion is revealed as a complex and challenging process that requires the active construction of a critical communicative space for dialectical and democratic learning for service development.

    2009-01-01

    Background In the current health care environment more patient care has moved from in-hospital care to the ambulatory primary care settings; however, fewer internal medicine residents are pursuing primary care careers. Barriers to residents developing a sense of competency and enjoyment in ambulatory medicine include the complexity of practice-based systems, patients with multiple chronic diseases, and the limited time that residents spend in the outpatient setting. Objective In an effort to accelerate residents' ambulatory care competence and enhance their satisfaction with ambulatory practice, we sought to change the learning environment. Interns were provided a series of intensive, focused, ambulatory training sessions prior to beginning their own continuity clinic sessions. The sessions were designed to enable them to work confidently and effectively in their continuity clinic from the beginning of the internship year, and it was hoped this would have a positive impact on their perception of the desirability of ambulatory practice. Methods Improvement needs assessment after a performance, so we developed a structured, competency-based, multidisciplinary curriculum for initiation into ambulatory practice. The curriculum focused on systems-based practice, patient safety, quality improvement, and collaborative work while emphasizing the importance of continuity of care and long-term doctor-patient relationships. Direct observation of patient encounters was done by an attending physician to evaluate communication and physical examination skills. Systems of care commonly used in the clinic were demonstrated. Resources for practice-based learning were used. Conclusion The immersion of interns in an intensive, hands-on experience using a structured ambulatory care orientation curriculum early in training may prepare the intern to be a successful provider and learner in the primary care ambulatory setting.

    , responses to this treatment in females and long-term effects on outcome are not known. Initial experiments used in vitro organ culture of cerebral arteries, confirming ERK1/2 activation and increased ETB receptor-mediated vasoconstriction in female cerebral arteries. Transient middle cerebral artery......-mediated contraction was studied with myograph and protein expression with immunohistochemistry. In vitro organ culture and tMCAO resulted in vascular ETB receptor upregulation and activation of ERK1/2 that was prevented by U0126. Although no effect on infarct size, U0126 improved the long-term neurologic function...

  11. Body talk among undergraduate women: why conversations about exercise and weight loss differentially predict body appreciation.

    2014-08-01

    Undergraduate women (N = 143) completed self-reports on exercise behavior, body orientation, body appreciation, and body-related talk. Results showed that conversations about weight loss/dieting and conversations about exercise differentially predicted body appreciation. Importantly, multiple regression analyses showed that the relationship between talk type and body appreciation was explained by the object-process dichotomy: Conversations about exercise oriented women to consider what their bodies can do which, in turn, predicted appreciation of one's body. In contrast, the relationship between conversations about weight loss/dieting and body appreciation was mediated by negative attitudes about one's body but not by an object orientation. © The Author(s) 2013.

    Communication in the intensive care unit (ICU) is an important component of quality ICU care. In this report, we evaluate the long-term effects of a quality improvement (QI) initiative, based on the VALUE communication strategy, designed to improve communication with family members of critically ill patients. We implemented a multifaceted intervention to improve communication in the ICU and measured processes of care. Quality improvement components included posted VALUE placards, templated progress note inclusive of communication documentation, and a daily rounding checklist prompt. We evaluated care for all patients cared for by the intensivists during three separate 3 week periods, pre, post, and 3 years following the initial intervention. Care delivery was assessed in 38 patients and their families in the pre-intervention sample, 27 in the post-intervention period, and 41 in follow-up. Process measures of communication showed improvement across the evaluation periods, for example, daily updates increased from pre 62% to post 76% to current 84% of opportunities. Our evaluation of this quality improvement project suggests persistence and continued improvements in the delivery of measured aspects of ICU family communication. Maintenance with point-of-care-tools may account for some of the persistence and continued improvements. Copyright © 2014 Elsevier Inc. All rights reserved.

    To study the long-term neurocognitive changes of a right-handed girl with intractable epilepsy after late right hemispherectomy and compare them with data in the literature. The girl was affected by an epileptic encephalopathy associated with right fronto-temporo-parietal polymicrogyria; she was submitted to right hemispherectomy at the age of 5 and examined with cognitive and neuropsychological tests at the age of 17 years. The girl took advantage of neurocognitive rehabilitation for several years; she is currently seizure-free and off therapy. At the end of the follow-up, the full-scale IQ is stable and within the normal range (p = 88). As the discrepancy between verbal IQ (pp = 120) and performance IQ (pp = 71) is significantly high, the girl was subjected to neurocognitive evaluation with the following results: verbal problem solving, verbal short- and long-term memory, and executive functions are within normal range. The most fragile functional areas are visual and spatial reasoning, verbal working memory, short-term visuospatial memory, visual attention, and processing speed, all > 2 SD. The spatial tests, such as coding, matrix reasoning, picture concepts, and arithmetic reasoning (which are favored by other functions such as associative memory and learning ability), are less severely impaired. These findings show that good conceptual skills and verbal reasoning can compensate for some deficits in visual-perceptual and visuospatial functions.

    The aim of the present study was to investigate the effects of a short-term in-season plyometric training program on power, agility and knee extensor strength. Male soccer players from a third league team were assigned into an experimental and a control group. The experimental group, beside its regular soccer training sessions, performed a periodized plyometric training program for six weeks. The program included two training sessions per week, and maximal intensity unilateral and bilateral plyometric exercises (total of 40 - 100 foot contacts/session) were executed. Controls participated only in the same soccer training routine, and did not perform plyometrics. Depth vertical jump height, agility (Illinois Agility Test, T Agility Test) and maximal voluntary isometric torque in knee extensors using Multicont II dynamometer were evaluated before and after the experiment. In the experimental group small but significant improvements were found in both agility tests, while depth jump height and isometric torque increments were greater. The control group did not improve in any of the measures. Results of the study indicate that plyometric training consisting of high impact unilateral and bilateral exercises induced remarkable improvements in lower extremity power and maximal knee extensor strength, and smaller improvements in soccer-specific agility. Therefore, it is concluded that short-term plyometric training should be incorporated in the in-season preparation of lower level players to improve specific performance in soccer.

However, the fluctuation of electricity price depends on the common effect of many factors and there is a very complicated random in its evolution process. Therefore, it is difficult to forecast half-hourly prices with traditional only one model for different behaviors of half-hourly prices. This paper proposes the improved forecasting model that detaches high volatility and daily seasonality for electricity price of New South Wales in Australia based on Empirical Mode Decomposition, Seasonal Adjustment and Autoregressive Integrated Moving Average. The prediction errors are analyzed and compared with the ones obtained from the traditional Seasonal Autoregressive Integrated Moving Average model. The comparisons demonstrate that the proposed model can improve the prediction accuracy noticeably.

    2013-12-01

    This study used a stochastic bioeconomic simulation model to simulate the business and financial risk of different broiler production systems over a 5-yr period. Simulation analysis was conducted using the @Risk add-in in MS Excel. To compare the impact of different production systems on economic feasibility, 2 cases were considered. The first case focused on the economic feasibility of a completely new system, whereas the second examined economic feasibilities when a farm switches from a conventional to an animal welfare-improving production system. A sensitivity analysis was conducted to assess the key drivers of economic feasibility and to reveal systematic differences across production systems. The study shows that economic feasibility of systems with improved animal welfare predominantly depends on the price that farmers receive. Moreover, the study demonstrates the importance of the level and variation of the price premium for improved welfare, particularly in the first 5 yr after conversion. The economic feasibility of the production system increases with the level of welfare improvements for a sufficiently high price level for broiler meat and low volatility in producer prices. If this is not the case, however, risk attitudes of farmers become important as well as the use of potential risk management instruments.

    Long-term oxygen therapy can increase life expectancy in hypoxemic patients with COPD. Accurate identification of hypoxemia requires arterial blood gas measurements. Pulse oximetry can be used to measure trends in oxygenation, oxygen needs, and oxygen requirements during exercise and sleep. A detailed oxygen prescription indicates: (1) the oxygen dose (L/min), (2) the number of hours per day that oxygen therapy is required, (3) the dose required during exercise, (4) the oxygen supply system: concentrator, compressed gas cylinder, or liquid oxygen reservoir, and (5) the delivery device: nasal cannula, demand-flow device, reservoir cannula, or transtracheal oxygen catheter.

    Isolated communities in the urban environment still use medicinal plants, but such knowledge is not always passed on to new generations. In this scenario, we propose a study with students, teachers, and community residents from Córrego da Ema, Amontada, Ceará, Brazil, aiming to know the wisdom of medicinal plants in a small rural community in the Brazilian semi-arid region. We interviewed the medicinal plant connoisseurs, named as local experts, by using the “snow ball” method. We applied questionnaires to investigate Elementary School students’ knowledge on medicinal plants (pre-tour. These actions provided a basis for planning guided-tours, activities aimed at 51 students, which we carried out along with the 10 experts and 2 local school teachers, whose results (post-tour were assessed by using the same pre-tour questionnaire. Most local experts were women (80%, their families had many people and low education level, factors that contribute to using medicinal plants. Experts cited 35 medicinal plant species. Students cited 24 pre-tour plant species and 28 post-tour plant species. Students increased their knowledge, as there was also a post-tour increase in therapeutic indications and preparation methods, as mentioned. The school played an important role in appreciating this intangible heritage, because it enabled actions involving formal and informal education.

    Using RIA method, the authors took 4 kinds of urine specimen from 100 normal persons which were taken in the morning 1 h after drinking voluntary and all- 24 h, and stored at 4 C deg and -30 C deg respectively, in order to detect the concentration of the urine protein Β 2 -MG, ALb, IgG and THP. The results are as follows: for 3-days-storage at 4 C deg and 2-weeks-storage at -30 C deg, P > 0.05; for the ALb, IgG and THP between voluntary urine and 24 h urine, α = 0.7565, 0.7865 and 0.7537 respectively; for Β 2 -MG, between the 1h-urine after drinking and voluntary urine, α = 0.7238. The urinary levels were measured of Β 2 -MG, ALb, IgG and THP with voluntary urine specimen in 177 cases of various types of nephropathy, urino-infection, and diabetic nephrosis, hypertesion-nephrosis, systemic lupus erythematosus. It is considered that the method of testing urine protein with voluntary urine specimen is not only accurate for collecting but also convenient for the patient. It is more accurate and sensitive than the traditional BUN and Cr for the appreciation of kidney function damage. And it gives a early stage index of kidney damage

    Full Text Available The professional development (PD of teachers plays an important role in schools; it is indispensable for continuous school development. When schools are exposed to new approaches to learning and teaching, teachers are granted the opportunities to change their thinking and behaviour. In 2009, two South African schools with specific inviting characteristics were nominated for the inviting school award given by the International Alliance for Invitational Education (IAIE. However, the inviting characteristics of these schools were not explicitly intentional according to the IE philosophy, therefore they had to follow a professional development programme aimed at raising teachers’ awareness of invitational education (IE. Workshops were held to equip staff members with IE knowledge and skills, and to increase their understanding of their current practices with a view of making them more intentionally inviting. The study focused on the following two questions: What are the positive experiences of teaching staff concerning the current approach to teaching and learning in schools?; and What strategies may be introduced to assist teachers and their schools in becoming intentionally inviting? These two questions are based on appreciative inquiry (AI and IE. A qualitative research design was most appropriate for the purpose of this study. An analysis of the data revealed two categories (the discovery phase: discovering the best of what exists in the school and the dreaming phase: creating a new future on which AI is based.

  10. Unpacking physics representations: Towards an appreciation of disciplinary affordance

    Directory of Open Access Journals (Sweden)

    Tobias Fredlund

    2014-12-01

    Full Text Available This theoretical article problematizes the access to disciplinary knowledge that different physics representations have the possibility to provide; that is, their disciplinary affordances. It is argued that historically such access has become increasingly constrained for students as physics representations have been rationalized over time. Thus, the case is made that such rationalized representations, while powerful for communication from a disciplinary point of view, manifest as learning challenges for students. The proposal is illustrated using a vignette from a student discussion in the physics laboratory about circuit connections for an experimental investigation of the charging and discharging of a capacitor. It is concluded that in order for students to come to appreciate the disciplinary affordances of representations, more attention needs to be paid to their “unpacking.” Building on this conclusion, two questions are proposed that teachers can ask themselves in order to begin to unpack the representations that they use in their teaching. The paper ends by proposing directions for future research in this area.

    Implementation of major organizational change initiatives presents a challenge for long-term care leadership. Implementation of the INTERACT® (Interventions to Reduce Acute Care Transfers) quality improvement program, designed to improve the management of acute changes in condition and reduce unnecessary emergency department visits and hospitalizations of nursing home residents, serves as an example to illustrate the facilitators and barriers to major change in long-term care. As part of a larger study of the impact of INTERACT® on rates of emergency department visits and hospitalizations, staff of 71 nursing homes were called monthly to follow-up on their progress and discuss successful facilitating strategies and any challenges and barriers they encountered during the yearlong implementation period. Themes related to barriers and facilitators were identified. Six major barriers to implementation were identified: the magnitude and complexity of the change (35%), instability of facility leadership (27%), competing demands (40%), stakeholder resistance (49%), scarce resources (86%), and technical problems (31%). Six facilitating strategies were also reported: organization-wide involvement (68%), leadership support (41%), use of administrative authority (14%), adequate training (66%), persistence and oversight on the part of the champion (73%), and unfolding positive results (14%). Successful introduction of a complex change such as the INTERACT® quality improvement program in a long-term care facility requires attention to the facilitators and barriers identified in this report from those at the frontline.

  12. Improved Reliability of SiC Pressure Sensors for Long Term High Temperature Applications

    Okojie, R. S.; Nguyen, V.; Savrun, E.; Lukco, D.

    2011-01-01

    We report advancement in the reliability of silicon carbide pressure sensors operating at 600 C for extended periods. The large temporal drifts in zero pressure offset voltage at 600 C observed previously were significantly suppressed to allow improved reliable operation. This improvement was the result of further enhancement of the electrical and mechanical integrity of the bondpad/contact metallization, and the introduction of studded bump bonding on the pad. The stud bump contact promoted strong adhesion between the Au bond pad and the Au die-attach. The changes in the zero offset voltage and bridge resistance over time at temperature were explained by the microstructure and phase changes within the contact metallization, that were analyzed with Auger electron spectroscopy (AES) and field emission scanning electron microscopy (FE-SEM).

  13. Short term economic emission power scheduling of hydrothermal energy systems using improved water cycle algorithm

    International Nuclear Information System (INIS)

    Haroon, S.S.; Malik, T.N.

    2017-01-01

    Due to the increasing environmental concerns, the demand of clean and green energy and concern of atmospheric pollution is increasing. Hence, the power utilities are forced to limit their emissions within the prescribed limits. Therefore, the minimization of fuel cost as well as exhaust gas emissions is becoming an important and challenging task in the short-term scheduling of hydro-thermal energy systems. This paper proposes a novel algorithm known as WCA-ER (Water Cycle Algorithm with Evaporation Rate) to inspect the short term EEPSHES (Economic Emission Power Scheduling of Hydrothermal Energy Systems). WCA has its ancestries from the natural hydrologic cycle i.e. the raining process forms streams and these streams start flowing towards the rivers which finally flow towards the sea. The worth of WCA-ER has been tested on the standard economic emission power scheduling of hydrothermal energy test system consisting of four hydropower and three thermal plants. The problem has been investigated for the three case studies (i) ECS (Economic Cost Scheduling), (ii) ES (Economic Emission Scheduling) and (iii) ECES (Economic Cost and Emission Scheduling). The results obtained show that WCA-ER is superior to many other methods in the literature in bringing lower fuel cost and emissions. (author)

  14. MultiLoc2: integrating phylogeny and Gene Ontology terms improves subcellular protein localization prediction

    Directory of Open Access Journals (Sweden)

    Kohlbacher Oliver

    2009-09-01

    Full Text Available Abstract Background Knowledge of subcellular localization of proteins is crucial to proteomics, drug target discovery and systems biology since localization and biological function are highly correlated. In recent years, numerous computational prediction methods have been developed. Nevertheless, there is still a need for prediction methods that show more robustness and higher accuracy. Results We extended our previous MultiLoc predictor by incorporating phylogenetic profiles and Gene Ontology terms. Two different datasets were used for training the system, resulting in two versions of this high-accuracy prediction method. One version is specialized for globular proteins and predicts up to five localizations, whereas a second version covers all eleven main eukaryotic subcellular localizations. In a benchmark study with five localizations, MultiLoc2 performs considerably better than other methods for animal and plant proteins and comparably for fungal proteins. Furthermore, MultiLoc2 performs clearly better when using a second dataset that extends the benchmark study to all eleven main eukaryotic subcellular localizations. Conclusion MultiLoc2 is an extensive high-performance subcellular protein localization prediction system. By incorporating phylogenetic profiles and Gene Ontology terms MultiLoc2 yields higher accuracies compared to its previous version. Moreover, it outperforms other prediction systems in two benchmarks studies. MultiLoc2 is available as user-friendly and free web-service, available at: http://www-bs.informatik.uni-tuebingen.de/Services/MultiLoc2.

    2016-01-01

    Full Text Available The general least squares model for milling process state term is presented. A discrete map for milling stability analysis that is based on the third-order case of the presented general least squares milling state term model is first studied and compared with its third-order counterpart that is based on the interpolation theory. Both numerical rate of convergence and chatter stability results of the two maps are compared using the single degree of freedom (1DOF milling model. The numerical rate of convergence of the presented third-order model is also studied using the two degree of freedom (2DOF milling process model. Comparison gave that stability results from the two maps agree closely but the presented map demonstrated reduction in number of needed calculations leading to about 30% savings in computational time (CT. It is seen in earlier works that accuracy of milling stability analysis using the full-discretization method rises from first-order theory to second-order theory and continues to rise to the third-order theory. The present work confirms this trend. In conclusion, the method presented in this work will enable fast and accurate computation of stability diagrams for use by machinists.

    2017-01-01

    Full Text Available The heating sector has begun implementing technologies and practices to tackle the environmental and social–economic problems caused by their production process. The purpose of this paper is to develop a methodology, “the Quick-Green-Scan”, that caters for the need of quick assessment decision-makers to improve green manufacturing performance in companies that produce heating devices. The study uses a structured approach that integrates Life Cycle Assessment-based indicators, framework and linguistic scales (fuzzy numbers to evaluate the extent of greening of the enterprise. The evaluation criteria and indicators are closely related to the current state of technology, which can be improved. The proposed methodology has been created to answer the question whether a company acts on the opportunity to be green and whether these actions are contributing towards greening, maintaining the status quo or moving away from a green outcome. Results show that applying the proposed improvements in processes helps move the facility towards being a green enterprise. Moreover, the methodology, being particularly quick and simple, is a practical tool for benchmarking, not only in the heating industry, but also proves useful in providing comparisons for facility performance in other manufacturing sectors.

    INTRODUCTION Fatigue and quality of sleep are the main factors that contribute to a poor quality of life among patients on long-term haemodialysis. Studies have also emphasised the importance of exercise for improving the wellbeing of dialysis patients. This study aimed to determine the effectiveness of a predialysis low-to-moderate-intensity exercise programme for reducing fatigue and improving sleep disorders among long-term haemodialysis patients. METHODS In this quasi-experimental study, an exercise programme was conducted three times a week for 12 weeks before long-term haemodialysis patients underwent dialysis at two centres. The patients were categorised into either the exercise group (n = 28) or control group (n = 27). The latter was asked to maintain their current lifestyles. Assessments of fatigue and sleep disorder levels were performed for both groups using self-reported questionnaires at baseline and after intervention. The patients’ perception of the exercise programme was also determined using self-reported questionnaires. RESULTS Paired sample t-test indicated improvements in fatigue level in the exercise group (mean fatigue score: post-treatment 40.5 ± 7.9 vs. pre-treatment 30.0 ± 10.9). Improvements in sleep disorders were also observed in the exercise group (mean score: post-treatment 7.6 ± 3.3 vs. pre-treatment 10.1 ± 3.8). However, sleep quality deteriorated in the control group (mean score: post-treatment 10.7 ± 2.9 vs. pre-treatment 9.3 ± 2.9). CONCLUSION Simple low-to-moderate-intensity exercise is effective for improving fatigue, sleep disorders and the overall quality of life among haemodialysis patients. PMID:25273932

    Full Text Available Onset stimulus can capture attention and then transfer into visual short-term memory. It remains unknown whether two sudden onsets also capture attention and are stored in vSTM. We modified Belopolsky, Kramer, and Godijn's (2008 visual search paradigm to test this issue. Experiment 1 using one onset and replicated Belopolsky et al's results. Two onsets in Experiment 2 were found to capture attention; however, recognition performance for the onsets was only at chance level, showing poor memory. Experiment 3 used a retro-cue to test whether only one of these two onsets can be stored in vSTM. Experiment 4 tested whehter this poor recognition was caused by interference from meory probe. This study has important insights on how attention interacts with memory.

    The discovery of transiting planets around bright stars holds the potential to greatly enhance our understanding of planetary atmospheres. The Transit Ephemeris Refinement and Monitoring Survey (TERMS) project focuses on updating the ephemerides of known exoplanets, put tighter constraints on the orbital parameters and shrink the large errors on the predicted transit windows, enabling photometric monitoring to search for a transit signature. Here, we present the revised orbital parameters and the photometric coverage during a predicted transit window of HD168443b, a massive planet orbiting the bright star HD 168443 (V = 6.92) with a period of 58.11 days. The high eccentricity of the planetary orbit (e = 0.53) significantly enhances the a-priori transit probability (3.7%) from what is expected for a circular orbit (2.5%). The transit ephemeris was updated using refined orbital parameters from additional Keck-HIRES radial velocities. The photometry obtained at the 1 m telescope in Cerro Tololo Inter-American Observatory (CTIO) and the T8 0.8 m Automated Photometric Telescope (APT) at Fairborn Observatory achieved the necessary millimag precision. The expected change in flux (0.5%) for HD168443 was not observed during the predicted transit window, thus allowing us to rule out the transit and put tighter constrains on the orbital inclination of HD168443b. Additionally, we present the software used to analyze the CTIO data. Developed by the TERMS team, this IDL based package is a fast, precise, and easy to use program which has eliminated the need for external software and command line prompts by utilizing the functionality of a graphical user interface (GUI).

    Xylem hydraulic conductance varies in response to changes in sap solute content, and in particular of potassium (K(+)) ion concentration. This phenomenon, known as the 'ionic effect', is enhanced in embolized stems, where it can compensate for cavitation-induced loss of hydraulic conductance. Previous studies have shown that in well-watered laurel plants (Laurus nobilis L.), potassium concentration of the xylem sap and plant hydraulic conductance increased 24 h after fertilization with KCl. The aim of this work was to test whether water-stressed laurel plants, grown under low potassium availability, could recover earlier from stress when irrigated with a KCl solution instead of potassium-free water. Two-year-old potted laurel seedlings were subjected to water stress by suspending irrigation until leaf conductance to water vapour (g(L)) dropped to ∼30% of its initial value and leaf water potential (ψ(L)) reached the turgor loss point (ψ(TLP)). Plants were then irrigated either with water or with 25 mM KCl and monitored for water status, gas exchange and plant hydraulics recovery at 3, 6 and 24 h after irrigation. No significant differences were found between the two experimental groups in terms of ψ(L), g(L), plant transpiration, plant hydraulic conductance or leaf-specific shoot hydraulic conductivity. Analysis of xylem sap potassium concentration showed that there were no significant differences between treatments, and potassium levels were similar to those of potassium-starved but well-watered plants. In conclusion, potassium uptake from the soil solution and/or potassium release to the xylem appeared to be impaired in water-stressed plants, at least up to 24 h after relief from water stress, so that fertilization after the onset of stress did not result in any short-term advantage for recovery from drought. © The Author 2014.

    Hygiene is becoming more and more important in long-term care facilities. Long-term care facilities are subject to monitoring by the Public Health Service (PHS) and other authorities. For the PHS in Bavaria the Bavarian Health and Food Safety Authority (Landesamt für Gesundheit und Lebensmittelsicherheit, LGL) published a hygiene monitoring concept and there exists an inspection guide developed by a specialist department for nursing homes and institutions for the handicapped (Fachstelle für Pflege und Behinderteneinrichtungen, FQA). Because inspections are performed in multiprofessional teams, it makes sense to use a coordinated inspection catalog. The aim was to integrate hygienic requirements specified in the Bavarian guidelines for hygiene by the LGL into the inspection guide published by the FQA to obtain a quality assured surveillance. The involved parties were questioned about the inspection guide and their hygiene management and then the hygiene criteria of the LGL were implemented into the inspection guide. Questions dealing with hygiene requirements concerning intensive care, management of multidrug resistant bacteria and interviews with the person responsible for infection control in the facility itself were developed for the first time and were integrated into the inspection guide. The revised inspection guide was tested for its applicability. With the revised inspection guide there now exists a tool which allows not only comprehensive inspections of the facilities including hygiene issues but also a good cooperation of the various parties involved. There are many actions which have to be conveyed into the future, especially programs to train staff to apply the inspection guide and to enhance the ability of all participants to act in cooperation. The guide will also allow the facilities to cooperate more easily and more closely, as the guide takes the respective problems and challenges of the different facilities into consideration. Additionally the

    Pattern informatics (PI), load/unload response ratio (LURR), state vector (SV), and accelerating moment release (AMR) are four previously unrelated subjects, which are sensitive, in varying ways, to the earthquake's source. Previous studies have indicated that the spatial extent of the stress perturbation caused by an earthquake scales with the moment of the event, allowing us to combine these methods for seismic hazard evaluation. The long-range earthquake forecasting method PI is applied to search for the seismic hotspots and identify the areas where large earthquake could be expected. And the LURR and SV methods are adopted to assess short-to-intermediate-term seismic potential in each of the critical regions derived from the PI hotspots, while the AMR method is used to provide us with asymptotic estimates of time and magnitude of the potential earthquakes. This new approach, by combining the LURR, SV and AMR methods with the choice of identified area of PI hotspots, is devised to augment current techniques for seismic hazard estimation. Using the approach, we tested the strong earthquakes occurred in Yunnan-Sichuan region, China between January 1, 2013 and December 31, 2014. We found that most of the large earthquakes, especially the earthquakes with magnitude greater than 6.0 occurred in the seismic hazard regions predicted. Similar results have been obtained in the prediction of annual earthquake tendency in Chinese mainland in 2014 and 2015. The studies evidenced that the ensemble approach could be a useful tool to detect short-to-intermediate-term precursory information of future large earthquakes.

    The type and duration of exposure to stress is an important influence on emotional and cognitive functions. Learning is the adaptive response of the central nervous system that occurs in hippocampus which affects from environmental factors like exercise. In this study, we investigated effects of long term treadmill exercise on learning and behavior on chronic social isolated rat. Male Wistar rats (n = 32) randomly assigned into four groups: control, exercised, social isolation, social isolation + exercise during postnatal days (PNDs) 21-34. Social isolation protocol was applied during 14 days by placing rat in a cage one by one. Rats were exercised during 5 days, days were chosen randomly for overall 4 weeks (20, 30, 50, 60 min respectively). Finally, learning performance was evaluated by Morris water maze (MWM). Anxiety behavior was evaluated by Open field and elevated plus maze test. At the end of learning and behavior tests, the rats were decapitated to collect blood samples via intracardiac puncture and corticosterone analysis was performed with ELISA method. Animal weights and water consumption did not change significantly but food intake differed among groups. Corticosterone level did not change between groups. The frequency of entering to the target quadrant increased in exercised rat significantly. However, there was no difference in learning and memory in rats. Treadmill exercise reduced anxiety behavior significantly. Taken together these findings may point out that, long term treadmill exercise did not change learning and memory but reduced anxiety level of rat without changing corticosterone level.

    Full Text Available Objectives: Autism spectrum disorder is a neurodevelopmental condition that typically displays socio-communicative impairment as well as restricted stereotyped interests and activities, in which gastrointestinal disturbances are commonly reported. We report the case of a boy with Autism Spectrum Disorder (ASD diagnosis, severe cognitive disability and celiac disease in which an unexpected improvement of autistic core symptoms was observed after four months of probiotic treatment. Method: The case study refers to a 12 years old boy with ASD and severe cognitive disability attending the Villa Santa Maria Institute in resident care since 2009. Diagnosis of ASDs according to DSM-V criteria was confirmed by ADOS-2 assessment (Autism Diagnostic Observation Schedule. The medication used was VSL#3, a multi-strain mixture of ten probiotics. The treatment lasted 4 weeks followed by a four month follow-up. The rehabilitation program and the diet was maintained stable in the treatment period and in the follow up. ADOS-2 was assessed six times: two times before starting treatment; two times during the treatment and two times after interruption of the treatment. Results: The probiotic treatment reduced the severity of abdominal symptoms as expected but an improvement in Autistic core symptoms was unexpectedly clinically evident already after few weeks from probiotic treatment start. The score of Social Affect domain of ADOS improved changing from 20 to 18 after two months treatment with a further reduction of 1 point in the following two months. The level 17 of severity remained stable in the follow up period. It is well known that ADOS score does not fluctuate spontaneously along time in ASD and is absolutely stable. Conclusions: The appropriate use of probiotics deserves further research, which hopefully will open new avenues in the fight against ASD.

    A 67-year-old man sequentially developed anti-Ma2-associated paraneoplastic encephalitis (PNE) and contralateral herpes simplex encephalitis (HSE). Brain biopsy 1 month before HSE revealed extensive infiltrates of T cells, B cells, and plasma cells. Most T cells expressed the cytotoxic granule-associated protein TIA-1 and the membranolytic protein granzyme-B. Although recovery was thought to be unlikely, treatment of the PNE with corticosteroids and resection of the associated lung cancer resulted in dramatic improvement for 21 months.

    The aim of this study was to determine whether intravenously administered multipotent stromal cells from human bone marrow (hMSCs) can improve cardiac function after myocardial infarction (MI) without long-term engraftment and therefore whether transitory paracrine effects or secreted factors are responsible for the benefit conferred. hMSCs were injected systemically into immunodeficient mice with acute MI. Cardiac function and fibrosis after MI in the hMSC-treated group were significantly improved compared with controls. However, despite the cardiac improvement, there was no evident hMSC engraftment in the heart 3 weeks after MI. Microarray assays and ELISAs demonstrated that multiple protective factors were expressed and secreted from the hMSCs in culture. Factors secreted by hMSCs prevented cell death of cultured cardiomyocytes and endothelial cells under conditions that mimicked tissue ischemia. The favorable effects of hMSCs appear to reflect the impact of secreted factors rather than engraftment, differentiation, or cell fusion

    The positive impact of Roux-en-Y gastric bypass on weight, comorbidities, and health-related quality of life is well documented. However, 50 percent of patients regain some of the lost weight after 2 years with Roux-en-Y gastric bypass and present a mean weight regain of 10 to 15 percent after several years, partially losing the previously obtained benefits. The authors hypothesize that body contouring could decrease weight regain, leading to better long-term weight control after Roux-en-Y gastric bypass. In a matched control study, variations in weight for 98 patients with body contouring after Roux-en-Y gastric bypass were compared with those of 102 matched control patients with Roux-en-Y gastric bypass alone. Data were collected prospectively at 1, 3, 6, 9, 12, and 18 months after Roux-en-Y gastric bypass and then yearly until 7 years. After a massive mean weight loss of 45.2 kg during the first 2 years after Roux-en-Y gastric bypass, patients with Roux-en-Y gastric bypass alone presented a higher continuous mean weight regain than those with Roux-en-Y gastric bypass and body contouring (1.78 kg/year versus 0.51 kg/year of weight regain, respectively; p = 0.001). After 7 years, patients with Roux-en-Y gastric bypass presented significantly higher mean weight regain than patients with Roux-en-Y gastric bypass and body contouring (i.e., 10.8 percent versus 3.6 percent mean weight gain, respectively; p weight of 2.04 kg by body contouring, the weight regain was 22.9 kg for patients with Roux-en-Y gastric bypass alone and only 6.2 kg for those with Roux-en-Y gastric bypass and body contouring. The authors demonstrated that patients with body contouring present better long-term weight control after Roux-en-Y gastric bypass. Therefore, body contouring must be considered as a reconstructive operation in the treatment of morbid obesity. Therapeutic, III.

    The Editors of the Journal of Geophysical Research Space Physics are deeply indebted to the many people among the research community that serve this journal through peer review. The journal could not exist without the time and effort invested by the community through this voluntary activity, providing expert evaluations and thoughtful assessments of the work of others. In 2015, the journal had 1506 scientists contribute to the process with at least one peer review, for a total of 3575 reviews completed, including additional reviews of resubmitted manuscripts. There were 277 reviewers that contributed four or more reports in 2015. The average number of reviews per referee in 2015 was, therefore, 2.4. Note that the total number of manuscript final decisions (i.e., accept or reject) for Journal of Geophysical Research (JGR) Space Physics was 1147 in 2015. Of this, 774 were accepted and 373 were declined, for an acceptance rate of 67% last year. If the 1334 "revision" decisions are included in the tally, then the total number of decisions made in 2015 was 2481. Working out the arithmetic, it means that on average, a manuscript gets about 1.2 revision decisions before a final accept-or-reject decision. This explains the 3.1 average number of reviews per manuscript throughout each paper's lifetime in the submission-revision editorial process. We are pleased and happy that the research community is willing and able to devote their resources toward this service endeavor. We appreciate each and every one of you that helped maintain the high quality of papers in JGR Space Physics last year. We look forward to another excellent year working with all of you through the year ahead.

    Improvements in neuroimaging methods have afforded significant advances in our knowledge of the cognitive and neural foundations of aesthetic appreciation. We used magnetoencephalography (MEG) to register brain activity while participants decided about the beauty of visual stimuli. The data were analyzed with event-related field (ERF) and Time-Frequency (TF) procedures. ERFs revealed no significant differences between brain activity related with stimuli rated as "beautiful" and "not beautiful." TF analysis showed clear differences between both conditions 400 ms after stimulus onset. Oscillatory power was greater for stimuli rated as "beautiful" than those regarded as "not beautiful" in the four frequency bands (theta, alpha, beta, and gamma). These results are interpreted in the frame of synchronization studies.

    Cement is a very good matrix for immobilization for different types of wastes. In India, the cementation process has been adopted and used for the last four decades. Depending on the waste composition, there is need to formulate the cement waste matrix appropriately to ensure adequate compressive strength and chemical durability. This has been achieved by using different additives/backfill materials during the cementation process with cements for example Ordinary Portland Cement (OPC) and Slag Based Cements (SBC). Backfill materials studied include vermiculite and bentonite. They were evaluated for sorption characteristics, particle size distribution, water equilibration, etc. They were incorporated in the OPC-CWP (Cement Waste Product) with various waste compositions. The composition developed for ILW generated during reprocessing and during spent solvent hydrolysis were successfully adopted on a plant scale. Some of the compositions which are being developed are also in the process of being adopted in-plant. The long-term evaluation study of the CWP was carried out at actual site conditions where CWP in carbon steel drum, plastic drums and bare CWP were disposed in 2001 and removed in 2010: parameters including compressive strength and release of activity to the soil were measured.

    Full Text Available Forecasting of electric load (EL is an important task for both electric power entities and large consumers of electricity [1]. Large consumers are faced with the need to compose applications for the planned volume of EL, and the deviation of subsequent real consumption from previously announced leads to the appearance of penalties from the wholesale market. In turn, electricity producers are interested in forecasting the demand for electricity for prompt response to its fluctuations and for the purpose of optimal infrastructure development. The most difficult and urgent task is the hourly forecasting of EL, which is extremely important for the successful solution of problems of optimization of generating capacities, minimization of power losses, dispatching control, security assessment of power supply, etc. Ultimately, such forecasts allow optimizing the cash costs for electricity and fuel or water consumption during generation. This paper analyzes the experience of the branch of JSC "SO UPS" Irkutsk Regional Dispatch Office of the procedure for short-term forecasting of the EL of the Irkutsk region.

    Both asthma and obstructive sleep apnoea cause sleep disturbance, daytime sleepiness and diminished quality of life. Continuous positive airway pressure (CPAP) is efficient in reducing symptoms related to sleep apnoea. Here we report the impact of long-term use of CPAP on asthma symptoms. A survey questionnaire was distributed to all of our obstructive sleep apnoea patients with CPAP therapy in 2013. We used the Finnish version of the Asthma Control Test™ (ACT) and a visual analogue scale (0 = no symptoms, 100 = severe asthma symptoms). Asthma was defined as self-reported physician-diagnosed disease and a special reimbursement for asthma medication by the Social Insurance Institution. We sent 2577 questionnaires and received 1586 answers (61 %). One hundred ninety-seven patients were asthmatics with a prevalence of asthma among CPAP users of 13 %. We studied 152 patients (58 females) whose CPAP therapy was initiated after starting asthma medication. Their mean (SD) age was 62 (10) years, duration of CPAP 5.7 (4.7) years and their CPAP daily use was 6.3 (2.4) h. Self-reported asthma severity decreased significantly from 48.3 (29.6) to 33.1 (27.4) (p CPAP (P CPAP in patients with both asthma and obstructive sleep apnoea.

    Psychosocial working conditions attract more and more attention when it comes to mental health in the workplace. Trying to support managers to deal with their own as well as their employees' psychological risk factors, we conducted a specific manager training. Within this investigation, we wanted to learn about the training's effects and acceptance. A single-day manager training was provided in a large industrial company in Germany. The participants were asked to fill out questionnaires regarding their own physical and mental health condition as well as their working situation. Questionnaires were distributed at baseline, 3-month, and 12-month follow-up. At this point of time the investigation is still ongoing. The current article focuses on short-term preliminary effects. Analyses only included participants that already completed baseline and three months follow-up. Preliminary results from three-month follow-up survey ( n = 33, nmale = 30, Mage = 47.5) indicated positive changes in the manager's mental health condition measured by the Patient Health Questionnaire for depression (PHQ-9: Mt1 = 3.82, Mt2 = 3.15). Training managers about common mental disorders and risk factors at the workplace within a single-day workshop seems to promote positive effects on their own mental health. Especially working with the managers on their own early stress symptoms might have been an important element.

    Visual feedback in general, and from the body in particular, is known to influence the performance of motor skills in humans. However, it is unclear how the acquisition of motor skills depends on specific visual feedback parameters such as the size of performing effector. Here, 21 healthy subjects physically trained to perform sequences of finger movements with their right hand. Through the use of 3D Virtual Reality devices, visual feedback during training consisted of virtual hands presented on the screen, tracking subject's hand movements in real time. Importantly, the setup allowed us to manipulate the size of the displayed virtual hands across experimental conditions. We found that performance gains increase with the size of virtual hands. In contrast, when subjects trained by mere observation (i.e., in the absence of physical movement), manipulating the size of the virtual hand did not significantly affect subsequent performance gains. These results demonstrate that when it comes to short-term motor skill learning, the size of visual feedback matters. Furthermore, these results suggest that highest performance gains in individual subjects are achieved when the size of the virtual hand matches their real hand size. These results may have implications for optimizing motor training schemes.

    Monitoring cancer survival is a key task of cancer registries, but timely disclosure of progress in long-term survival remains a challenge. We introduce and evaluate a novel method, denoted "boomerang method," for deriving more up-to-date estimates of long-term survival. We applied three established methods (cohort, complete, and period analysis) and the boomerang method to derive up-to-date 10-year relative survival of patients diagnosed with common solid cancers and hematological malignancies in the United States. Using the Surveillance, Epidemiology and End Results 9 database, we compared the most up-to-date age-specific estimates that might have been obtained with the database including patients diagnosed up to 2001 with 10-year survival later observed for patients diagnosed in 1997-2001. For cancers with little or no increase in survival over time, the various estimates of 10-year relative survival potentially available by the end of 2001 were generally rather similar. For malignancies with strongly increasing survival over time, including breast and prostate cancer and all hematological malignancies, the boomerang method provided estimates that were closest to later observed 10-year relative survival in 23 of the 34 groups assessed. The boomerang method can substantially improve up-to-dateness of long-term cancer survival estimates in times of ongoing improvement in prognosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Neural changes were investigated for children with disruptive behavior problems one year after a treatment program ended. Thirty-nine children and their parents visited the research lab before, after, and a year after treatment ended. During those lab visits, electroencephalography (EEG was recorded during a challenging Go/No-go task. Treatment consisted of intensive 14-week combined cognitive behavioral therapy and parent management training sessions. For the analysis, participants were divided into long-term improvers (IMPs and long-term nonimprovers (NIMPs based on changes in their externalizing problem scores. The results showed early no-go theta power (4–8 Hz, 100–250 ms decreased for long-term IMPs compared to NIMPs. When participants were divided based on changes in their comorbid internalizing symptoms, effects were stronger and reductions in theta power were found for early as well as later phases (250–650 ms. We provided preliminary evidence that theta power is a useful neural measure to trace behavioral change linked to improved self-regulation even up to a year after treatment ended. Results may have implications for the characterization of children with disruptive behavior problems and may lead to the development of novel markers of treatment success.

  6. Prognostic factors for short-term improvement in acute and persistent musculoskeletal pain consulters in primary care

    Full Text Available Abstract Background Given the costs associated with the management of musculoskeletal pain in primary care, predicting the course of these conditions remains a research priority. Much of the research into prognostic indicators however considers musculoskeletal conditions in terms of single pain sites whereas in reality, many patients present with pain in more than one site. The aim of this study was to identify prognostic factors for early improvement in primary care consulters with acute and persistent musculoskeletal conditions across a range of pain sites. Methods Consecutive patients with a new episode of musculoskeletal pain completed self-report questionnaires at baseline, and then again at the 4/5th treatment visit, and if they were still consulting, at the 10th visit. The outcome was defined as patient self-report improvement sufficient to make a meaningful difference. Independent predictors of outcome were identified using multivariate regression analyses. Results Acute (th visit. Several variables at baseline were associated with improvement at the 4/5th visit, but the predictive models were weak and unable to discriminate between patients who were improved and those who were not. In contrast, it was possible to elicit a predictive model for improvement later on at the 10th visit, but only in patients with persistent pain. Being employed, reporting a decline in work fear-avoidance behaviour at the 4/5th visit, and being better by the 4/5th visit, were all independently associated with improvement. This model accounted for 34.3% (p Conclusions We were unable to identify baseline characteristics that predicted early outcome in musculoskeletal pain patients. However, early self-reported improvement and decline in work fear-avoidance behaviour as predictors of later improvement highlighted the importance of speedy recovery in persistent musculoskeletal pain consulters. Our findings reinforce the elusive nature of baseline predictors, and

    If general practitioners (GPs) were better informed about patients' risks of long-term sickness absence (LTSA), they could incorporate these risk assessments into their patient management plans and cooperate more with occupational physicians to prevent LTSA. To evaluate the effectiveness of a protocol helping GPs in recording risks of LTSA and in co-operating with occupational physicians (OPs). Twenty-six GPs (co-operating in four groups) in Amsterdam, The Netherlands, participated in a controlled intervention study. Fourteen GPs were the protocol-supported intervention group and twelve GPs were the reference group. Outcome measures were consultations containing work-related information, information about two risk factors for LTSA, referrals to OPs and contacts of OPs with GPs and patients. Outcomes were identified through an electronic search in the GPs' information systems. Entries containing information were independently scored by two investigators. The proportions of patients with consultations documenting LTSA-pertinent items were compared between the groups, accounting for differences at baseline. There was no increase in consultations containing work-related information. Recording of risk factor information increased in the intervention group; the difference was 4.5% [95% CI 1.5-7.6] and 1.8% (95% CI -0.8 to 4.4) for the two risk factors. The referral rate to the OP increased by 2.9% (95% CI 1.2-4.5). There was no effect on contacts of OPs with GPs or with patients. Protocol-supported consultations may lead to a modest increase in information regarding two risk factors for LTSA in GPs' electronic records and to more referrals to OPs.

    The use of unfractionated heparin (UFH) as an anticoagulant during long-term extracorporeal support presents a unique challenge for the clinician in balancing the amount of anticoagulant to maintain adequate anticoagulation without causing excessive bleeding. Activated clotting times (ACT) and activated partial thromboplastin times (aPTT) are the most common modality to monitor UFH on extracorporeal membrane oxygenation (ECMO). Limitations to these tests include consumptive coagulopathies, clotting factor deficiencies, platelet dysfunction, and fibrinolysis. The following case report describes the use of alternative monitoring strategies to assess more accurately anticoagulation during ECMO. A 20-month-old female presented to the emergency department with a 5-6 day history of cough, fever, tachypnea, and respiratory distress. She was diagnosed with influenza A and B with pneumonia. The patient was placed on veno-venous ECMO (V-V ECMO) after mechanical ventilation failed. On ECMO day eight, the patient developed a thrombus in her inferior vena cava and pleural effusions, obstructing cannula flow. Laboratory tests revealed the ACT was within range, yet the aPTT was dropping, despite increased heparin. Heparin levels were low and antithrombin-III (AT) concentrations were 40%. Recombinant AT was given and subsequent aPTTs were within the therapeutic range. Later, the aPTT decreased to 475 mg/ dL, and Factor VIII >150 IU/dL, suggesting an acute phase reaction or ongoing systemic inflammation, increasing the risk for thrombosis. We maintained heparin assays between 0.5-0.7 IU/mL and AT >60% to assure heparin's effect. The patient showed no signs of excess bleeding, blood product administration, or clots in the circuit, suggesting proper anticoagulation. The patient was successfully weaned on day 33 and is currently alive and at home. Monitoring of anti-Xa UFH and AT proved effective for measuring anticoagulation and detecting inconsistencies in other anticoagulation

    During long duration journeys, drivers are encouraged to take regular breaks. The benefits of breaks have been documented for safety; breaks may also be beneficial for comfort. The activity undertaken during a break may influence its effectiveness. Volunteers completed 3 journeys on a driving simulator. Each 130 min journey included a 10 min break after the first hour. During the break volunteers either stayed seated, left the simulator and sat in an adjacent room, or took a walk on a treadmill. The results show a reduction in driver discomfort during the break for all 3 conditions, but the effectiveness of the break was dependent on activity undertaken. Remaining seated in the vehicle provided some improvement in comfort, but more was experienced after leaving the simulator and sitting in an adjacent room. The most effective break occurred when the driver walked for 10 min on a treadmill. The benefits from taking a break continued until the end of the study (after a further hour of driving), such that comfort remained the best after taking a walk and worst for those who remained seated. It is concluded that taking a break and taking a walk is an effective method for relieving driving discomfort. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Tourism is an important component of the economic and social life of a country. The importance of the role of tourism in the national economy is given by the complexity of this phenomenon, the scope of activities necessary for its emergence, maintenance and development. Tourism plays an important role on the human level too, due to its positive effects for the tourists and also for the population of the host countries. For tourist, the tourism means creating conditions and opportunities for rest, relaxation, culture or getting in touch with other people, and for the local people tourism is a mean of raising the standards of living, improving the living conditions. By its nature, the tourism represents an economic activity located at the crossroads of other branches. In this tourism universe, the power of the consumer does not cease to exist, that is why the quality is one of the first requirements as customer or tourist satisfaction is greatly dependent on the quality of the services. In order to enter into the international tourism competition is needed the modernization, recovery and development of the Romanian tourism and creation of modern and competitive tourism products on the tourism market.

    The purpose of the study was to observe changes in the skeletal system of rats with subclinical hypothyroidism (SCH) and to determine whether L-thyroxine (L-T4) administration suppresses those changes. Sixty male Wistar rats were randomly divided into control, SCH, and SCH+T4 groups. SCH was induced in rats by administration of methimazole (MMI), and rats in the SCH+T4 group were treated with L-T4 after 45 days of MMI administration. The SCH group had higher thyroid-stimulating hormone (TSH) level than the control and SCH+T4 groups. There were no differences in serum thyroid hormone (FT4 and FT3) levels among the three groups. Bone mineral density; serum levels of BALP and TRACP-5b, two bone metabolic markers; and the biomechanical properties of the femurs were lower in the SCH group than in the control group. After L-T4 treatment, serum BALP and TRACP-5b levels and the femur biomechanical properties were higher in the SCH+T4 than the SCH group. Histopathological examination revealed damage to the structure of the femur trabecular bone network in rats with SCH, and L-T4 treatment improved this condition to some extent. These findings demonstrate that L-T4 treatment ameliorates the destructive effects of SCH on the skeletal system in rats.

    The purpose of the analysis was to develop a health economic model to estimate the costs and health benefits of alternative National Health Service (NHS) service configurations for people with longer-term depression. Modelling methods were used to develop a conceptual and health economic model of the current configuration of services in Sheffield, England for people with longer-term depression. Data and assumptions were synthesised to estimate cost per Quality Adjusted Life Years (QALYs). Three service changes were developed and resulted in increased QALYs at increased cost. Versus current care, the incremental cost-effectiveness ratio (ICER) for a self-referral service was £11,378 per QALY. The ICER was £2,227 per QALY for the dropout reduction service and £223 per QALY for an increase in non-therapy services. These results were robust when compared to current cost-effectiveness thresholds and accounting for uncertainty. Cost-effective service improvements for longer-term depression have been identified. Also identified were limitations of the current evidence for the long term impact of services.

    Few research studies have examined longitudinal improvements in oral communication skills and quality of peer relationships of children with implants. Moreover, although the emerging literature suggests that improvement in social functioning follows improvement in oral communication, it is still unknown what factors enhance or impede the relations between these constructs. Based on parent interviews, the current study examined the long-term improvements in speech and oral language skills and relationships with hearing peers in 19 implanted children. Results demonstrate that on average, children continue to improve in oral communication skills and quality of peer relationships even years after implantation, especially those with initial poorer skills. While oral communication ability and quality of peer relationships are strongly associated at each time point, gains in these two variables are associated only for some of the children. Other factors, including self-confidence and peer acceptance, seem to moderate this relationship. Qualitative data are presented to illustrate these relations among variables and to assist in theory building. The results highlight the need for more specific examination of various developmental periods in combination with the progress of oral communication and peer relationships among children with implants. © 2013 John Wiley & Sons Ltd.

    Obesity is a major cause of insulin resistance, and weight loss is shown to improve glucose homeostasis. But the underlying mechanism and the role of inflammation remain unclear. Male C57BL/6 mice were fed a high-fat diet (HFD) for 12 wk. After HFD, weight loss was induced by changing to a low-fat diet (LFD) or exercise with continuous HFD. The weight loss effects on energy balance and insulin sensitivity were determined using metabolic cages and hyperinsulinemic euglycemic clamps in awake mice. Diet and exercise intervention for 3 wk caused a modest weight loss and improved glucose homeostasis. Weight loss dramatically reduced local inflammation in skeletal muscle, liver, and heart but not in adipose tissue. Exercise-mediated weight loss increased muscle glucose metabolism without affecting Akt phosphorylation or lipid levels. LFD-mediated weight loss reduced lipid levels and improved insulin sensitivity selectively in liver. Both weight loss interventions improved cardiac glucose metabolism. These results demonstrate that a short-term weight loss with exercise or diet intervention attenuates obesity-induced local inflammation and selectively improves insulin sensitivity in skeletal muscle and liver. Our findings suggest that local factors, not adipose tissue inflammation, are involved in the beneficial effects of weight loss on glucose homeostasis.

    The objective of this project is to address waterflood problems of the type found in Morrow sandstone reservoirs in southwestern Kansas and in Cherokee Group reservoirs in southeastern Kansas. Two demonstration sites operated by different independent oil operators are involved in this project. The Stewart Field is located in Finney County, Kansas and is operated by PetroSantander, Inc. Te Nelson Lease is located in Allen County, Kansas, in the N.E. Savonburg Field and is operated by James E. Russell Petroleum, Inc. General topics to be addressed are (1) reservoir management and performance evaluation, (2) waterflood optimization, and (3) the demonstration of recovery processes involving off-the-shelf technologies which can be used to enhance waterflood recovery, increase reserves, and reduce the abandonment rate of these reservoir types. In the Stewart Project, the reservoir management portion of the project conducted during Budget Period 1 involved performance evaluation. This included (1) reservoir characterization and the development of a reservoir database, (2) volumetric analysis to evaluate production performance, (3) reservoir modeling, (4) laboratory work, (5) identification of operational problems, (6) identification of unrecovered mobile oil and estimation of recovery factors, and (7) Identification of the most efficient and economical recovery process. To accomplish these objectives the initial budget period was subdivided into three major tasks. The tasks were (1) geological and engineering analysis, (2) laboratory testing, and (3) unitization. Due to the presence of different operators within the field, it was necessary to unitize the field in order to demonstrate a field-wide improved recovery process. This work was completed and the project moved into Budget Period 2

  1. Improving Long-term Post-wildfire hydrologic simulations using ParFlow

    Science.gov (United States)

    Lopez, S. R.; Kinoshita, A. M.

    2015-12-01

    Wildfires alter the natural hydrologic processes within a watershed. After vegetation is burned, the combustion of organic material and debris settles into the soil creating a hydrophobic layer beneath the soil surface with varying degree of thickness and depth. Vegetation regrowth rates vary as a function of radiative exposure, burn severity, and precipitation patterns. Hydrologic models used by the Burned Area Emergency Response (BAER) teams use input data and model calibration constraints that are generally either one-dimensional, empirically-based models, or two-dimensional, conceptually-based models with lumped parameter distributions. These models estimate runoff measurements at the watershed outlet; however, do not provide a distributed hydrologic simulation at each point within the watershed. This work uses ParFlow, a three-dimensional, distributed hydrologic model to (1) correlate burn severity with hydrophobicity, (2) evaluate vegetation recovery rate on water components, and (3) improve flood prediction for managers to help with resource allocation and management operations in burned watersheds. ParFlow is applied to Devil Canyon (43 km2) in San Bernardino, California, which was 97% burned in the 2003 Old Fire. The model set-up uses a 30m-cell size resolution over a 6.7 km by 6.4 km lateral extent. The subsurface reaches 30 m and is assigned a variable cell thickness. Variable subsurface thickness allows users to explicitly consider the degree of recovery throughout the stages of regrowth. Burn severity maps from remotely sensed imagery are used to assign initial hydrophobic layer parameters and thickness. Vegetation regrowth is represented with satellite an Enhanced Vegetation Index. Pre and post-fire hydrologic response is evaluated using runoff measurements at the watershed outlet, and using water component (overland flow, lateral flow, baseflow) measurements.

    This study aims to explore correlates between body appreciation and mental health among a racially and ethnically diverse sample of adult women using validated measures. The sample included racially and ethnically diverse women ( N = 497) from various socioeconomic levels. Linear regression results indicated that body appreciation was significantly and inversely associated with depression ( b = -3.68; p < 0.001). In this sample, as body appreciation increased, depression scores decreased. Similarly, body appreciation was significantly and inversely associated with anxiety among this sample ( b = -1.78; p < 0.001). This article concludes with a discussion of findings and implications.

    Accelerated long term forgetting (ALF) is a characteristic cognitive aspect in patients affected by temporal lobe epilepsy that is probably due to an impairment of memory consolidation and retrieval caused by epileptic activity in hippocampal and parahippocampal regions. We describe a case of a patient with TLE who showed improvement in ALF and in remote memory impairment after an anterior left temporal pole lobectomy including the uncus and amygdala. Our findings confirm that impairment of hippocampal functioning leads to pathological ALF, whereas restoration of hippocampal functioning brings ALF to a level comparable to that of controls.

    The passive and active release of bioaerosols during green waste composting, measured at source is reported for a commercial composting facility in South East (SE) England as part of a research programme focused on improving risk assessments at composting facilities. Aspergillus fumigatus and actinomycetes concentrations of 9.8-36.8×10 6 and 18.9-36.0×10 6 cfu m -3, respectively, measured during the active turning of green waste compost, were typically 3-log higher than previously reported concentrations from static compost windrows. Source depletion curves constructed for A. fumigatus during compost turning and modelled using SCREEN3 suggest that bioaerosol concentrations could reduce to background concentrations of 10 3 cfu m -3 within 100 m of this site. Authentic source term data produced from this study will help to refine the risk assessment methodologies that support improved permitting of compost facilities.

    In order to solve the model of short-term cascaded hydroelectric system scheduling, a novel chaotic particle swarm optimization (CPSO) algorithm using improved logistic map is introduced, which uses the water discharge as the decision variables combined with the death penalty function. According to the principle of maximum power generation, the proposed approach makes use of the ergodicity, symmetry and stochastic property of improved logistic chaotic map for enhancing the performance of particle swarm optimization (PSO) algorithm. The new hybrid method has been examined and tested on two test functions and a practical cascaded hydroelectric system. The experimental results show that the effectiveness and robustness of the proposed CPSO algorithm in comparison with other traditional algorithms.

    To evaluate voice function in patients with adductor spasmodic dysphonia (AdSD) who discontinued botulinum toxin (BTX) treatment because they felt that their voice had improved sufficiently. Twenty-eight patients quit treatment in 2004, of whom 20 fulfilled the inclusion criteria for the study, with 3 subsequently excluded because of return of symptoms, leaving 17 patients (11 males, 6 females) included in this follow-up study. A questionnaire concerning current voice function and the Voice Handicap Index were completed. Audio-perceptual voice assessments were done by 3 listeners. The inter- and intrarater reliabilities were r > 0.80. All patients had a subjectively good stable voice, but with differences in their audio-perceptual voice assessment scores. Based on the pre-/posttreatment auditory scores on the overall degree of AdSD, patients were divided into 2 subgroups showing more and less improvement, with 10 and 7 patients, respectively. The subgroup with more improvement had shorter duration from the onset of symptoms until the start of BTX treatment, and included 7 males compared to only 4 males in the subgroup with less improvement. It seems plausible that the symptoms of spasmodic dysphonia may decrease over time. Early intervention and male gender seem to be important factors for long-term reduction of the voice symptoms of AdSD. © 2016 S. Karger AG, Basel.

    Computerised clinical decision support systems (CCDSS) are used to improve the quality of care in various healthcare settings. This systematic review evaluated the impact of CCDSS on improving medication safety in long-term care homes (LTC). Medication safety in older populations is an important health concern as inappropriate medication use can elevate the risk of potentially severe outcomes (ie, adverse drug reactions, ADR). With an increasing ageing population, greater use of LTC by the growing ageing population and increasing number of medication-related health issues in LTC, strategies to improve medication safety are essential. Databases searched included MEDLINE, EMBASE, Scopus and Cochrane Library. Three groups of keywords were combined: those relating to LTC, medication safety and CCDSS. One reviewer undertook screening and quality assessment. Overall findings suggest that CCDSS in LTC improved the quality of prescribing decisions (ie, appropriate medication orders), detected ADR, triggered warning messages (ie, related to central nervous system side effects, drug-associated constipation, renal insufficiency) and reduced injury risk among older adults. CCDSS have received little attention in LTC, as attested by the limited published literature. With an increasing ageing population, greater use of LTC by the ageing population and increased workload for health professionals, merely relying on physicians' judgement on medication safety would not be sufficient. CCDSS to improve medication safety and enhance the quality of prescribing decisions are essential. Analysis of review findings indicates that CCDSS are beneficial, effective and have potential to improve medication safety in LTC; however, the use of CCDSS in LTC is scarce. Careful assessment on the impact of CCDSS on medication safety and further modifications to existing CCDSS are recommended for wider acceptance. Due to scant evidence in the current literature, further research on implementation and

    High-pressure inflation for coronary stent deployment is universally performed. However, the duration of inflation is variable and does not take into account differences in lesion compliance. We developed a standardized "pressure optimization protocol" (POP) using inflation pressure stability rather than an arbitrary inflation time or angiographic balloon appearance for stent deployment. Whether this approach improves long-term outcomes is unknown. 792 patients who underwent PCI using either rapid inflation/deflation (n = 376) or POP (n = 416) between January 2009 and March 2014 were included. Exclusion criteria included PCI for acute myocardial infarction, in-stent restenosis, chronic total occlusion, left main, and saphenous vein graft lesions. Primary endpoint was target vessel failure [TVF = combined end point of target vessel revascularization (TVR), myocardial infarction, and cardiac death]. Outcomes were analyzed in the entire cohort and in a propensity analysis. Stent implantation using POP with a median follow-up of 1317 days was associated with lower TVF compared with rapid inflation/deflation (10.1 vs. 17.8%, P inflation/deflation (10 vs. 18%, P < 0.0001). Stent deployment using POP led to reduced TVF compared to rapid I/D. These results recommend this method to improve long-term outcomes. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    A major issue facing many government and private industry sites that were previously contaminated with radioactive and chemical wastes is that often the sites cannot be cleaned up enough to permit unrestricted human access. These sites will require long-term management, in some cases indefinitely, leaving site owners with the challenge of protecting human health and environmental quality in a cost effective manner. Long-term monitoring of groundwater contamination is one of the largest projected costs in the life cycle of environmental management at the Savannah River Site (SRS), the larger DOE complex, and many large federal and private sites. Currently, most monitoring strategies are focused on laboratory measurements of contaminants measured in groundwater samples collected from wells. This approach is expensive, and provides limited and lagging information about the effectiveness of cleanup activities and the behavior of the residual contamination. Over the last twenty years, DOE and other federal agencies have made significant investments in the development of various types of sensors and strategies that would allow for remote analysis of contaminants in groundwater, but these approaches do not promise significant reductions in risk or cost. Scientists at SRS have developed a new paradigm to simultaneously improve the performance of long term monitoring systems while lowering the overall cost of monitoring. This alternative approach incorporates traditional point measurements of contaminant concentration with measurements of controlling variables including boundary conditions, master variables, and traditional plume/contaminant variables. Boundary conditions are the overall driving forces that control plume movement and therefore provide leading indication to changes in plume stability. These variables include metrics associated with meteorology, hydrology, hydrogeology, and land use. Master variables are the key variables that control the chemistry of the

  12. Short-term, informal, and low-stakes scientific laboratory and field experiences improve STEM student retention and academic success

    Formal internship experiences strongly improve student success in the STEM fields. Classical programs like NSF's Research Experiences for Undergraduates are highly successful for traditional and non-traditional students. Moreover when early undergraduate and at-risk (e.g., low income, academically-challenged) students engage in these experiences, their career paths are re-enforced or changed, academic progress and retention improves, and they are encouraged to continue into graduate school. Students build connections to their course-based learning and experience the life of a working scientist. However, NSF formal experiences are relatively expensive to provide (>5000 per student per experience) and are available to fewer than 5% of geoscience majors each year. Although other funded formal internship opportunities exist, they are likely available to no more than 10% of total enrolled geoscience students. These high-quality programs cannot impact enough early undergraduate students to encourage their remaining in science and improve the current overall retention and graduation rates in the US. Savannah State University faculty successfully completed multiple grants funding low-stakes undergraduate field-science experiences. These short-term (semester to year), part-time (5-10h/week) experiences provide similar classroom-to-real-world science connections, offer students direct laboratory and field experiences, build skill sets, and provide a small source of revenue assisting financially-challenged students to stay on campus rather than seeking off-campus employment. For a much lower investment in time and grant resources (500-1500 per student per experience), participant graduation rates exceeded 80%, well above the university 27-34% graduation rate during the same time period. Relatively small infusions of research dollars targeting undergraduate experiences in the field and laboratory could significantly impact long-term student outcomes in STEM disciplines. These

    Artworks with sad and affectively negative content have repeatedly been reported to elicit positive aesthetic appreciation. This topic has received much attention both in the history of poetics and aesthetics as well as in recent studies on sad films and sad music. However, poetry and aesthetic evaluations of joyful and sad poetry have received only little attention in empirical studies to date. We collected beauty and liking ratings for 24 sad and 24 joyful poems from 128 participants. Following previous studies, we computed an integrated measure for overall aesthetic appreciation based on the beauty and liking ratings to test for differences in appreciation between joyful and sad poems. Further, we tested whether readers' judgments are related to their affinity for poetry. Results show that sad poems are rated significantly higher for aesthetic appreciation than joyful poems, and that aesthetic appreciation is influenced by the participants' affinity for poetry.

    The aim of the current study was to examine associations between body appreciation and putative correlates that focus on self-enhancement and self-expression. Students (N=261; mean age=20.16years, SD=3.68; 60.9% female) from a non-residential college in the northeastern United States completed a questionnaire measuring body appreciation, interest in cosmetic enhancements, and need for uniqueness. Individuals with higher body appreciation and African Americans/Blacks reported significantly higher self-attributed need for uniqueness and significantly higher investment in a distinctive appearance. The association between body appreciation and interest in cosmetic enhancements (e.g., hair coloring) was not significant. Results suggest that body appreciation may be linked to a desire to express one's own unique qualities. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Bariatric surgery for morbid obesity results in massive weight loss and improvement of health and quality of life. A downside of the major weight loss is the excess of overstretched skin, which may influence the patient's quality of life by causing functional and aesthetic problems. The purpose of the current study was to evaluate the patient's quality of life long-term after body contouring following bariatric surgery. Quality of life was measured with the Obesity Psychosocial State Questionnaire in 33 post-bariatric surgery patients 7.2 years (range, 3.2 to 13.3 years) after body contouring surgery. Data were compared with previous assessments 4.1 years (range, 0.7 to 9.2 years) after body contouring surgery of the quality of life at that time and before body contouring surgery. Compared with appraisals of quality of life before body contouring surgery, a significant, mostly moderate to large, sustained improvement of quality of life was observed in post-bariatric surgery patients 7.2 years after body contouring surgery in six of the seven psychosocial domains. A small deterioration occurred between 4.1- and 7.2-year follow-up on two of the seven domains except for the domain efficacy toward eating, which showed a significant improvement. At 7-year follow-up, 18 patients (55 percent) were satisfied with the result of body contouring surgery. This study indicates a sustained quality-of-life improvement in post-bariatric surgery patients after body contouring surgery. This suggests the importance of including reconstructive surgery as a component in the multidisciplinary approach in the surgical treatment of morbid obesity. Therapeutic, IV.

    Sparse data are available on long-term patient mortality following bariatric surgery as compared to the general population. The purpose of this study was to assess long-term mortality rates and identify risk factors for all-cause mortality following bariatric surgery. New York State (NYS) Planning and Research Cooperative System (SPARCS) longitudinal administrative data were used to identify 7,862 adult patients who underwent a primary laparoscopic bariatric surgery from 1999 to 2005. The Social Security Death Index database identified >30-day mortalities. Risk factors for mortality were screened using a univariate Cox proportional hazard (PH) model and analyzed using a multiple PH model. Based on age, gender, and race/ethnicity, actuarial projections for NYS mortality rates obtained from Centers of Disease Control were compared to the actual post-bariatric surgery mortality rates observed. The mean bariatric mortality rate was 2.5 % with 8-14 years of follow-up. Mean time to death ranged from 4 to 6 year and did not differ by operation (p = 0.073). From 1999 to 2010, the actuarial mortality rate predicted for the general NYS population was 2.1 % versus the observed 1.5 % for the bariatric surgery population (p = 0.005). Extrapolating to 2013, demonstrated the actuarial mortality predictions at 3.1 % versus the bariatric surgery patients' observed morality rate of 2.5 % (p = 0.01). Risk factors associated with an earlier time to death included: age, male gender, Medicare/Medicaid insurance, congestive heart failure, rheumatoid arthritis, pulmonary circulation disorders, and diabetes. No procedure-specific or perioperative complication impact for time-to-death was found. Long-term mortality rate of patients undergoing bariatric surgery significantly improves as compared to the general population regardless of bariatric operation performed. Additionally, perioperative complications do not increase long-term mortality risk. This study did identify specific patient

    Full Text Available Abstract Background There is considerable evidence about the effectiveness of audit coupled with feedback, although few audit with feedback interventions have been conducted in long-term care (LTC settings to date. In general, the effects have been found to be modest at best, although in settings where there has been little history of audit and feedback, the effects may be greater, at least initially. The primary purpose of the Data for Improvement and Clinical Excellence (DICE Long-Term Care project is to assess the effects of an audit with feedback intervention delivered monthly over 13 months in four LTC facilities. The research questions we addressed are: 1. What effects do feedback reports have on processes and outcomes over time? 2. How do different provider groups in LTC and home care respond to feedback reports based on data targeted at improving quality of care? Methods/design The research team conducting this study comprises researchers and decision makers in continuing care in the province of Alberta, Canada. The intervention consists of monthly feedback reports in nine LTC units in four facilities in Edmonton, Alberta. Data for the feedback reports comes from the Resident Assessment Instrument Minimum Data Set (RAI version 2.0, a standardized instrument mandated for use in LTC facilities throughout Alberta. Feedback reports consist of one page, front and back, presenting both graphic and textual information. Reports are delivered to all staff working in the four LTC facilities. The primary evaluation uses a controlled interrupted time series design both adjusted and unadjusted for covariates. The concurrent process evaluation uses observation and self-report to assess uptake of the feedback reports. Following the project phase described in this protocol, a similar intervention will be conducted in home care settings in Alberta.

    Attention deficit hyperactivity disorder (ADHD) is characterized by impairing levels of hyperactivity, impulsivity and inattention. However, different meta-analyses have reported disruptions in short and long-term memory in ADHD patients. Previous studies indicate that mnemonic dysfunctions might be the result of deficits in attentional circuits, probably due to ineffective dopaminergic modulation of hippocampal synaptic plasticity. In this study we aimed to evaluate the potential therapeutic effects of a neuromodulatory technique, transcranial direct current stimulation (tDCS), in short-term memory (STM) deficits presented by the spontaneous hypertensive rats (SHR), the most widely used animal model of ADHD. Adult male SHR and Wistar Kyoto rats (WKY) were subjected to a constant electrical current of 0.5 mA intensity applied on the frontal cortex for 20 min/day during 8 days. STM was evaluated with an object recognition test conducted in an open field. Exploration time and locomotion were recorded, and brain regions were dissected to determine dopamine and BDNF levels. SHR spent less time exploring the new object when compared to WKY, and tDCS improved object recognition deficits in SHR without affecting WKY performance. Locomotor activity was higher in SHR and it was not affected by tDCS. After stimulation, dopamine levels were increased in the hippocampus and striatum of both strains, while BDNF levels were increased only in the striatum of WKY. These findings suggest that tDCS on the frontal cortex might be able to improve STM deficits present in SHR, which is potentially related to dopaminergic neurotransmission in the hippocampus and striatum of those animals.

    Previous investigations have demonstrated that choline deficiency, manifested in low plasma-free choline concentration and hepatic injury, may develop in patients who require long-term total parenteral nutrition (TPN). Preliminary studies have suggested lecithin or choline supplementation might lead to improved visual memory in the elderly and reverse abnormal neuropsychological development in children. We sought to determine if choline-supplemented TPN would lead to improvement in neuropsychological test scores in a group of adult, choline-deficient outpatients receiving TPN. Eleven subjects (8 males, 3 females) who received nightly TPN for more than 80% of their nutritional needs for at least 12 weeks before entry in the study were enrolled. Exclusion criteria included active drug abuse, mental retardation, cerebral vascular accident, head trauma, hemodialysis or peritoneal dialysis, (prothrombin time [PT] >2x control), or acquired immune deficiency syndrome (AIDS). Patients were randomly assigned to receive their usual TPN regimen (n = 6, aged 34.0 +/- 12.6 years) over a 12-hour nightly infusion or their usual TPN regimen plus choline chloride (2 g) (n = 5, aged 37.3 +/- 7.3 years). The following neuropsychological tests were administered at baseline and after 24 weeks of choline supplementation (or placebo): Weschler Adult Intelligence Scale-Revised (WAIS-R, intellectual functioning), Weschler Memory Scale-Revised (WMS-R, two subtests, verbal and visual memory), Rey-Osterrieth Complex Figure Test (visuospatial functioning and perceptual organization), Controlled Oral Word Association Test (verbal fluency), Grooved Pegboard (manual dexterity and motor speed), California Verbal Learning Test (CVLT, rote verbal learning ability), and Trail Making Parts A & B (visual scanning, psychomotor speed and set shifting). Scores were reported in terms of standard scores including z scores and percentile ranks. Mean absolute changes in raw scores were compared between groups

    It is widely noted in the literature that the degradation should be simplified into a memoryless Markovian process for the purpose of predicting the remaining useful life (RUL). However, there actually exists the long-term dependency in the degradation processes of some industrial systems, including electromechanical equipments, oil tankers, and large blast furnaces. This implies the new degradation state depends not only on the current state, but also on the historical states. Such dynamic systems cannot be accurately described by traditional Markovian models. Here we present an improved non-Markovian degradation model with both the long-term dependency and the item-to-item uncertainty. As a typical non-stationary process with dependent increments, fractional Brownian motion (FBM) is utilized to simulate the fractal diffusion of practical degradations. The uncertainty among multiple items can be represented by a random variable of the drift. Based on this model, the unknown parameters are estimated through the maximum likelihood (ML) algorithm, while a closed-form solution to the RUL distribution is further derived using a weak convergence theorem. The practicability of the proposed model is fully verified by two real-world examples. The results demonstrate that the proposed method can effectively reduce the prediction error.

    Hydrological time series forecasting is one of the most important applications in modern hydrology, especially for the effective reservoir management. In this research, an artificial neural network (ANN) model coupled with the ensemble empirical mode decomposition (EEMD) is presented for forecasting medium and long-term runoff time series. First, the original runoff time series is decomposed into a finite and often small number of intrinsic mode functions (IMFs) and a residual series using EEMD technique for attaining deeper insight into the data characteristics. Then all IMF components and residue are predicted, respectively, through appropriate ANN models. Finally, the forecasted results of the modeled IMFs and residual series are summed to formulate an ensemble forecast for the original annual runoff series. Two annual reservoir runoff time series from Biuliuhe and Mopanshan in China, are investigated using the developed model based on four performance evaluation measures (RMSE, MAPE, R and NSEC). The results obtained in this work indicate that EEMD can effectively enhance forecasting accuracy and the proposed EEMD-ANN model can attain significant improvement over ANN approach in medium and long-term runoff time series forecasting.

    An athlete's ability to recover quickly is important when there is limited time between training and competition. As such, recovery strategies are commonly used to expedite the recovery process. To determine the effectiveness of both cold-water immersion (CWI) and contrast water therapy (CWT) compared with control on short-term recovery (<4 h) after a single full-body resistance-training session. Thirteen men (age 26 ± 5 y, weight 79 ± 7 kg, height 177 ± 5 cm) were assessed for perceptual (fatigue and soreness) and performance measures (maximal voluntary isometric contraction [MVC] of the knee extensors, weighted and unweighted countermovement jumps) before and immediately after the training session. Subjects then completed 1 of three 14-min recovery strategies (CWI, CWT, or passive sitting [CON]), with the perceptual and performance measures reassessed immediately, 2 h, and 4 h postrecovery. Peak torque during MVC and jump performance were significantly decreased (P < .05) after the resistance-training session and remained depressed for at least 4 h postrecovery in all conditions. Neither CWI nor CWT had any effect on perceptual or performance measures over the 4-h recovery period. CWI and CWT did not improve short-term (<4-h) recovery after a conventional resistance-training session.

    While carbon and energy fluxes in current Earth system models generally have reasonable instantaneous responses to extreme temperature and precipitation events, they often do not adequately represent the long-term impacts of these events. For example, simulated net primary productivity (NPP) may decrease during an extreme heat wave or drought, but may recover rapidly to pre-event levels following the conclusion of the extreme event. However, field measurements indicate that long-lasting damage to leaves and other plant components often occur, potentially affecting the carbon and energy balance for months after the extreme event. The duration and frequency of such extreme conditions is likely to shift in the future, and therefore it is critical for Earth system models to better represent these processes for more accurate predictions of future vegetation productivity and land-atmosphere feedbacks. Here we modify the structure of the Accelerated Climate Model for Energy (ACME) land surface model to represent long-term impacts and test the improved model against observations from experiments that applied extreme conditions in growth chambers. Additionally, we test the model against eddy covariance measurements that followed extreme conditions at selected locations in North America, and against satellite-measured vegetation indices following regional extreme events.

    Purpose: In a retrospective analysis, adjuvant intensity-modulated radiation therapy (IMRT) combined with modern chemotherapy improved advanced gastric cancer survival rates compared to a combination of three-dimensional conformal radiation therapy (3D-CRT) and conventional chemotherapy. We report on the long-term outcomes of two consecutive patient cohorts that were treated with either IMRT and intensive chemotherapy, or 3D-CRT and conventional chemotherapy. Patients and methods: Between 2001 and 2008, 65 consecutive gastric cancer patients received either 3D-CRT (n = 27) or IMRT (n = 38) following tumor resection. Chemotherapy comprised predominantly 5-fluorouracil/folinic acid (5-FU/FA) in the earlier cohort and capecitabine plus oxaliplatin (XELOX) in the latter. The primary endpoints were overall survival (OS) and disease-free survival (DFS). Results: Median OS times were 18 and 43 months in the 3D-CRT and IMRT groups, respectively (p = 0.0602). Actuarial 5-year OS rates were 26 and 47 %, respectively. Within the IMRT group, XELOX gave better results than 5-FU/FA in terms of OS, but this difference was not statistically significant. The primary cause of death in both groups was distant metastasis. Median DFS times were 14 and 35 months in the 3D-CRT and IMRT groups, respectively (p = 0.0693). Actuarial 5-year DFS rates were 22 and 44 %, respectively. Among patients receiving 5-FU/FA, DFS tended to be better in the IMRT group, but this was not statistically significant. A similar analysis for the XELOX group was not possible as 3D-CRT was almost never used to treat these patients. No late toxicity exceeding grade 3 or secondary tumors were observed. Conclusion: After a median follow-up period of over 5 years, OS and DFS were improved in the IMRT/XELOX treated patients compared to the 3D-CRT/5-FU/FA group. Long-term observation revealed no clinical indications of therapy-induced secondary tumors or renal toxicity. (orig.)

    This study aimed to examine the protective role of positive body image against negative effects produced by viewing thin-idealised media. University women (N=68) completed trait measures of body appreciation and media protective strategies. At a subsequent session, participants viewed 11 thin-ideal advertisements. Body dissatisfaction was assessed before and after advertisement exposure, and state measures of self-objectification, appearance comparison, and media protective strategies were completed. Results indicated that body appreciation predicted less change in body dissatisfaction following exposure, such that participants with low body appreciation experienced increased body dissatisfaction, while those with high body appreciation did not. Although state appearance comparison predicted increased body dissatisfaction, neither state self-objectification nor appearance comparison accounted for body appreciation's protective effect. Trait and state media protective strategies positively correlated with body appreciation, but also did not account for body appreciation's protective effect. The results point to intervention targets and highlight future research directions. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Genome reprogramming in early mouse embryos is associated with nuclear reorganization and particular features such as the peculiar distribution of centromeric and pericentric heterochromatin during the first developmental stage. This zygote-specific heterochromatin organization could be observed both in maternal and paternal pronuclei after natural fertilization as well as in embryonic stem (ES cell nuclei after nuclear transfer suggesting that this particular type of nuclear organization was essential for embryonic reprogramming and subsequent development. Results Here, we show that remodeling into a zygotic-like organization also occurs after somatic cell nuclear transfer (SCNT, supporting the hypothesis that reorganization of constitutive heterochromatin occurs regardless of the source and differentiation state of the starting material. However, abnormal nuclear remodeling was frequently observed after SCNT, in association with low developmental efficiency. When transient treatment with the histone deacetylase inhibitor trichostatin A (TSA was tested, we observed improved nuclear remodeling in 1-cell SCNT embryos that correlated with improved rates of embryonic development at subsequent stages. Conclusion Together, the results suggest that proper organization of constitutive heterochromatin in early embryos is involved in the initial developmental steps and might have long term consequences, especially in cloning procedures.

    Full Text Available Mesenchymal stem cells (MSCs are an attractive cell source for cartilage tissue engineering given their ability to undergo chondrogenesis in 3D culture systems. Mechanical forces play an important role in regulating both cartilage development and MSC chondrogenic gene expression, however, mechanical stimulation has yet to enhance the mechanical properties of engineered constructs. In this study, we applied long-term dynamic compression to MSC-seeded constructs and assessed whether varying pre-culture duration, loading regimens and inclusion of TGF-beta3 during loading would influence functional outcomes and these phenotypic transitions. Loading initiated before chondrogenesis decreased functional maturation, although chondrogenic gene expression increased. In contrast, loading initiated after chondrogenesis and matrix elaboration further improved the mechanical properties of MSC-based constructs, but only when TGF-beta3 levels were maintained and under specific loading parameters. Although matrix quantity was not affected by dynamic compression, matrix distribution, assessed histologically and by FT-IRIS analysis, was significantly improved on the micro- (pericellular and macro- (construct expanse scales. Further, whole genome expression profiling revealed marked shifts in the molecular topography with dynamic loading. These results demonstrate, for the first time, that dynamic compressive loading initiated after a sufficient period of chondro-induction and with sustained TGF-beta exposure enhances matrix distribution and the mechanical properties of MSC-seeded constructs.

    The aim of this study was to assess the effects of long-term nebivolol therapy on high blood pressure, impaired endothelial function in aorta, and damage observed in heart and conductance arteries in spontaneously hypertensive rats (SHR). For this purpose, SHR were treated for 9 weeks with nebivolol (8 mg/kg per day). Untreated SHR and Wistar Kyoto rats were used as hypertensive and normotensive controls, respectively. The left ventricle/body weight ratio was used as an index of cardiac hypertrophy, and to evaluate vascular function, responses induced by potassium chloride, noradrenaline, acetylcholine, and sodium nitroprusside were tested on aortic rings. Aortic morphometry and fibrosis were determined in parallel by a quantitative technique. Systolic blood pressure, measured by the tail-cuff method, was lower in treated SHR than in the untreated group (194 +/- 3 versus 150 +/- 4 mm Hg). The cardiac hypertrophy index was significantly reduced by the treatment. In aortic rings, treatment with nebivolol significantly reduced the maximal response to both KCl and NA in SHR. In vessels precontracted with phenylephrine relaxant, activity due to acetylcholine was higher in normotensive rats than in SHR and the treatment significantly improved this response. The effect of sodium nitroprusside on aortic rings was similar in all groups. Medial thickness and collagen content were significantly reduced in comparison with SHR. In conclusion, the chronic antihypertensive effect of nebivolol in SHR was accompanied by an improvement in vascular structure and function and in the cardiac hypertrophy index.

    Full Text Available Chronic kidney disease (CKD is one of the major manifestations of paroxysmal nocturnal hemoglobinuria (PNH. CKD in PNH is induced mainly by intravascular hemolysis of PNH-affected red blood cells (RBC missing the glycosylphosphatidylinositol-anchored proteins with complement-regulatory activities, CD55 and CD59. CKD develops by heme absorption in the proximal tubules resulting in the interstitial deposition of iron in the kidneys. We administered eculizumab to a patient with PNH, who was one of 29 patients enrolled in the AEGIS clinical trial, an open-label study of eculizumab in Japan. The patient was complicated by stage 3 CKD with impaired estimated glomerular filtration rate (eGFR, at grade G3b, and had obvious proteinuria (2-3+, 1-2 g/day. In a two-year extension to the 12-week AEGIS study, eGFR improved significantly, and the eGFR has since been maintained at grade G2 without proteinuria by sustained eculizumab treatment (>6 years. Renal function improved and maintained by long-term sustained eculizumab treatment, presumably by clearance of iron from the kidney as well as inhibition of the production of anaphylatoxin C5a, even in advanced stages of CKD, is one of the benefits of eculizumab treatment in PNH.

    A major issue facing many government and private industry sites that were previously contaminated with radioactive and chemical wastes is that often the sites cannot be cleaned up enough to permit unrestricted human access. These sites will require long-term management, in some cases indefinitely, leaving site owners with the challenge of protecting human health and environmental quality in a cost effective manner. Long-term monitoring of groundwater contamination is one of the largest projected costs in the life cycle of environmental management at the Savannah River Site (SRS), the larger DOE complex, and many large federal and private sites. Currently, most monitoring strategies are focused on laboratory measurements of contaminants measured in groundwater samples collected from wells. This approach is expensive, and provides limited and lagging information about the effectiveness of cleanup activities and the behavior of the residual contamination. Over the last twenty years, DOE and other federal agencies have made significant investments in the development of various types of sensors and strategies that would allow for remote analysis of contaminants in groundwater, but these approaches do not promise significant reductions in risk or cost. Scientists at SRS have developed a new paradigm to simultaneously improve the performance of long term monitoring systems while lowering the overall cost of monitoring. This alternative approach incorporates traditional point measurements of contaminant concentration with measurements of controlling variables including boundary conditions, master variables, and traditional plume/contaminant variables. Boundary conditions are the overall driving forces that control plume movement and therefore provide leading indication to changes in plume stability. These variables include metrics associated with meteorology, hydrology, hydrogeology, and land use. Master variables are the key variables that control the chemistry of the

    The problem of inadequate access to water, sanitation and hygiene (WASH) in less-developed nations has received much attention over the last several decades (most recently in the Millennium Development Goals), largely because diseases associated with such conditions contribute substantially to mortality in poor countries. We present country-level projections for WASH coverage and for WASH-related mortality in developing regions over a long time horizon (1975-2050) and provide dynamic estimates of the economic value of potential reductions in this WASH-related mortality, which go beyond the static results found in previous work. Over the historical period leading up to the present, our analysis shows steady and substantial improvements in WASH coverage and declining mortality rates across many developing regions, namely East Asia and the Pacific, Latin America and the Caribbean, Eastern Europe and the Middle East. The economic value of potential health gains from eliminating mortality attributable to poor water and sanitation has decreased substantially, and in the future will therefore be modest in these regions. Where WASH-related deaths remain high (in parts of South Asia and much of Sub-Saharan Africa), if current trends continue, it will be several decades before economic development and investments in improved water and sanitation will result in the capture of these economic benefits. The fact that health losses will likely remain high in these two regions over the medium term suggests that accelerated efforts are needed to improve access to water and sanitation, though the costs and benefits of such efforts in specific locations should be carefully assessed.

  3. Self-compassionate actions and disordered eating behavior in women: The mediator effect of body appreciation

    Directory of Open Access Journals (Sweden)

    Andreia Máximo

    2017-09-01

    Conclusions: Present results suggest that self-compassionate actions hold a protective effect on eating behavior through higher levels of respect and appreciation toward body image, despite body weight, shape, and imperfections. The ability to act following self-compassionate motivations seems to contribute to higher levels of body image appreciation, which reflects in a lower susceptibility to adopt disordered eating attitudes and behaviors. The present study seems to represent an important contribution to research and clinical practice and underlines the importance of including strategies to develop self-compassionate and body appreciation competencies in programs to prevent and intervene in the area of eating psychopathology.

    Despite the availability of modern antibiotics/antimycotics and cytokine support, neutropenic infection accounts for the majority of chemotherapy-associated deaths. While transfusion support with donor neutrophils is possible, cost and complicated logistics make such an option unrealistic on a routine basis. A manufactured neutrophil product could enable routine prophylactic administration of neutrophils, preventing the onset of neutropenia and substantially reducing the risk of infection. We examined the use of pre-culture strategies and various cytokine/modulator combinations to improve neutrophil expansion from umbilical cord blood (UCB) hematopoietic stem and progenitor cells (HPC). Enriched UCB HPC were cultured using either two-phase pre-culture strategies or a single phase using various cytokine/modulator combinations. Outcome was assessed with respect to numerical expansion, cell morphology, granulation and respiratory burst activity. Pre-culture in the absence of strong differentiation signals (e.g. granulocyte colony-stimulating factor; G-CSF) failed to provide any improvement to final neutrophil yields. Similarly, removal of differentiating cells during pre-culture failed to improve neutrophil yields to an appreciable extent. Of the cytokine/modulator combinations, the addition of granulocyte-macrophage (GM)-colony-stimulating factor (CSF) alone gave the greatest increase. In order to avoid production of monocytes, it was necessary to remove GM-CSF on day 5. Using this strategy, neutrophil expansion improved 2.7-fold. Although all cytokines and culture strategies employed have been reported previously to enhance HPC expansion, we found that the addition of GM-CSF alone was sufficient to improve total cell yields maximally. The need to remove GM-CSF on day 5 to avoid monocyte differentiation highlights the context and time-dependent complexity of exogenous signaling in hematopoietic cell differentiation and growth.

  5. Undervaluing Gratitude: Expressers Misunderstand the Consequences of Showing Appreciation.

    2018-06-01

    Expressing gratitude improves well-being for both expressers and recipients, but we suggest that an egocentric bias may lead expressers to systematically undervalue its positive impact on recipients in a way that could keep people from expressing gratitude more often in everyday life. Participants in three experiments wrote gratitude letters and then predicted how surprised, happy, and awkward recipients would feel. Recipients then reported how receiving an expression of gratitude actually made them feel. Expressers significantly underestimated how surprised recipients would be about why expressers were grateful, overestimated how awkward recipients would feel, and underestimated how positive recipients would feel. Expected awkwardness and mood were both correlated with participants' willingness to express gratitude. Wise decisions are guided by an accurate assessment of the expected value of action. Underestimating the value of prosocial actions, such as expressing gratitude, may keep people from engaging in behavior that would maximize their own-and others'-well-being.

  6. Intermingled Bodies. Distributed Agency in an Expanded Appreciation of Making

    Directory of Open Access Journals (Sweden)

    Terence E. Rosenberg

    2013-09-01

    Full Text Available This article offers an expanded view of making and, concomitantly, an understanding that through making we constitute the way we are in the world. The article begins with the idea that making produces a 'surrogate' of the body, which extends the body into the world, reforming the body and the world and their relationship. The ideas the article offers run counter to certain currents of thought that reduce making to a narrow cast anthropocentric crafting. Instead of this reduction, where making is merely understood and fixated as a close inembodied handicraft, the article advances: first, that all that we produce is making – not just that which is crafted by the immediacy of a hand; and, second, and linked to this expanded view of making, that all making workst hrough a distributed agency that includes human and non-human actors and actants in meshworks that extend across space – synchronous - and across time –diachronous. In other words, the body is extended into the world through what is made and this made world acts ineluctably on, and in, making. The paper references the practices of three makers to make the case for the need, bothethical and poetic, to think about making as an expanded term and to consideran intentionality of making that works through distributed agency doubly constituted as material and narrative.

    Oligosaccharides in human milk may protect infants by improving the intestinal micro-flora and fermentation. This study was to investigate effects of infant formula milk consisting of galacto-oligosaccharide (GOS) on intestinal microbial populations and the fermentation characteristics in term infants in comparison with that of human milk. The test formula (Frisolac H, Friesland, Netherland) was supplemented with GOS at a concentration of 0.24 g/dl. Human milk and another formula without oligosaccharides (Frisolac H, Friesland, Netherland) were used as positive and negative control respectively. Growth, stool characteristics, and side effects of the recruited infants were recorded after 3 and 6 months' follow-up, and the fecal species were collected for the analysis of intestinal micro-flora, short chain fatty acid (SCFA) and pH. At the end of 3- and 6-month feeding period, intestinal Bifidobacteria and Lactobacilli were significantly increased in infants fed with GOS supplemented formula and human milk when compared with infants fed with negative control formula; however, there was no statistically significant difference between GOS supplemented formula and human milk groups. Stool characteristics were influenced by the supplement and main fecal SCFA (acetic), and stool frequency were significantly increased in infants fed with GOS supplemented formula and human milk, while the fecal pH was significantly decreased as compared with that of negative control (P effects (including crying, regurgitation and vomiting). Supplementing infant formula with GOS at a concentration of 0.24 g/dl stimulates the growth of Bifidobacteria and Lactobacilli in the intestine and stool characteristics are similar to in term infants fed with human milk.

  9. Fibroblasts accelerate islet revascularization and improve long-term graft survival in a mouse model of subcutaneous islet transplantation.

    Directory of Open Access Journals (Sweden)

    Marcos Perez-Basterrechea

    Full Text Available Pancreatic islet transplantation has been considered for many years a promising therapy for beta-cell replacement in patients with type-1 diabetes despite that long-term clinical results are not as satisfactory. This fact points to the necessity of designing strategies to improve and accelerate islets engraftment, paying special attention to events assuring their revascularization. Fibroblasts constitute a cell population that collaborates on tissue homeostasis, keeping the equilibrium between production and degradation of structural components as well as maintaining the required amount of survival factors. Our group has developed a model for subcutaneous islet transplantation using a plasma-based scaffold containing fibroblasts as accessory cells that allowed achieving glycemic control in diabetic mice. Transplanted tissue engraftment is critical during the first days after transplantation, thus we have gone in depth into the graft-supporting role of fibroblasts during the first ten days after islet transplantation. All mice transplanted with islets embedded in the plasma-based scaffold reversed hyperglycemia, although long-term glycemic control was maintained only in the group transplanted with the fibroblasts-containing scaffold. By gene expression analysis and histology examination during the first days we could conclude that these differences might be explained by overexpression of genes involved in vessel development as well as in β-cell regeneration that were detected when fibroblasts were present in the graft. Furthermore, fibroblasts presence correlated with a faster graft re-vascularization, a higher insulin-positive area and a lower cell death. Therefore, this work underlines the importance of fibroblasts as accessory cells in islet transplantation, and suggests its possible use in other graft-supporting strategies.

This fact points to the necessity of designing strategies to improve and accelerate islets engraftment, paying special attention to events assuring their revascularization. Fibroblasts constitute a cell population that collaborates on tissue homeostasis, keeping the equilibrium between production and degradation of structural components as well as maintaining the required amount of survival factors. Our group has developed a model for subcutaneous islet transplantation using a plasma-based scaffold containing fibroblasts as accessory cells that allowed achieving glycemic control in diabetic mice. Transplanted tissue engraftment is critical during the first days after transplantation, thus we have gone in depth into the graft-supporting role of fibroblasts during the first ten days after islet transplantation. All mice transplanted with islets embedded in the plasma-based scaffold reversed hyperglycemia, although long-term glycemic control was maintained only in the group transplanted with the fibroblasts-containing scaffold. By gene expression analysis and histology examination during the first days we could conclude that these differences might be explained by overexpression of genes involved in vessel development as well as in β-cell regeneration that were detected when fibroblasts were present in the graft. Furthermore, fibroblasts presence correlated with a faster graft re-vascularization, a higher insulin-positive area and a lower cell death. Therefore, this work underlines the importance of fibroblasts as accessory cells in islet transplantation, and suggests its possible use in other graft-supporting strategies.

    Interventions to improve quality of care for residents of long-term care facilities, and to examine the sustainability and spread of such initiatives, remain a top research priority. The purpose of this exploratory study was to assess the extent to which activities initiated in a quality improvement (QI) collaborative study using care aide led teams were sustained or spread following cessation of the initial project and to identify factors that led to its success. This study used an exploratory mixed methods study design and was conducted in seven residential long-term care facilities in two Canadian provinces. Sustainability and spread of QI activities were assessed by a questionnaire over five time points for 18 months following the collaborative study with staff from both intervention with non-intervention units. Semi-structured interviews were conducted with care managers at six and 12 months. QI team success in applying the QI model was ranked as high, medium, or low using criteria developed by the research team. Descriptive statistics, bivariate analyses, and General Estimating Equations were used to analyze the data. Interview data were analyzed using thematic analysis. In total, 683 surveys were received over the five time periods from 476 unique individuals on a facility unit. Seven managers were interviewed. A total of 533 surveys were analyzed. While both intervention and non-intervention units experienced a decline over time in all outcome measures, this decline was significantly less pronounced on intervention units. Facilities with medium and high success ranking had significantly higher scores in all four outcomes than facilities with a low success ranking. Care aides reported significantly less involvement of others in QI activities, less empowerment and less satisfaction with the quality of their work life than regulated care providers. Manager interviews provided evidence of sustainability of QI activities on the intervention units in four of

    Youth in out-of-home care have higher rates of sexual risk behaviors and pregnancy than youth nationally. This study aimed to determine if Power Through Choices (PTC), a teen pregnancy prevention program developed for youth in out-of-home care, significantly improves knowledge and psychosocial outcomes regarding HIV and sexually transmitted infections (STIs), sexual activity and contraception methods, long term. A cluster randomized controlled trial was conducted with 1,036 ethnically diverse youths (aged 13-18 years) recruited from 44 residential group homes in three states. Intervention participants received the 10-session PTC intervention; control participants received usual care. Participants were administered self-report surveys at baseline, after intervention, 6 and 12 months after the intervention. Survey items assessed knowledge, attitudes, self-efficacy, and behavioral intentions regarding HIV and STIs, sexual activity and contraception methods. Random intercept logistic regression analyses were used to assess differences between the intervention and control groups. Compared with youth in the control group, youth in the PTC intervention demonstrated significant improvements in knowledge about anatomy and fertility (adjusted odds ratio [AOR] = 1.07, 95% confidence interval [CI] = 1.03-1.11), HIV and STIs (AOR = 1.03, 95% CI = 1.002-1.07), and methods of protection (AOR = 1.06, 95% CI = 1.03-1.09), as well as self-efficacy regarding self-efficacy to communicate with a partner (AOR = 1.14, 95% CI = 1.04-1.26), plan for protected sex and avoid unprotected sex (AOR = 1.16, 95% CI = 1.04-1.28), and where to get methods of birth control (AOR = 1.13, 95% CI = 1.01-1.26) 12 months after the intervention. Findings suggest that the PTC intervention can have positive long-term knowledge and psychosocial effects regarding contraception methods on youth in out-of-home care.

    Full Text Available The paper studies determinants of flexibility of the nominal effective exchange rate and the effects of exchange rate shocks on macroeconomic variables and key components of the external balances using data for a sample of advanced and developing countries. The composite evidence points to the positive effects of appreciation through cheaper imports in support of higher growth and lower price inflation in advanced and developing countries. However, the negative effects of appreciation are more pervasive on the external balances in developing countries. The implication is developing countries remain highly dependent on exports of commodities. In contrast, advanced countries are more diversified and ahead in capitalizing on currency appreciation to mobilize investment growth, a channel that boosts competitiveness and mitigates the adverse effect of appreciation on external stability. The evidence attests to the need to create an environment that is more conducive to investment growth in developing countries.

    2007-07-01

    Increasingly complex environments in which nurse educators must function create distinct challenges for leaders in nursing education. Complexity is found in the presence of knowledge-driven economies, advancements in technology, and the blurring of campus boundaries created by online learning versus traditional classroom education. A dual bureaucracy of faculty and administration coexists in nursing education. The transformation of bureaucratic culture is a strategic challenge for academic leaders who strive to move dichotomous groups toward a collective vision of a preferred future. This article advocates for the affirmative administrative process of appreciative inquiry for academic nursing leadership, in nudging the dual bureaucracy toward transformational change. The intent and characteristics of appreciative inquiry are discussed, appreciative leadership strategies and actions are explained, methods for leading cultural paradigm shift are outlined, and an exemplar of the actualization of appreciative inquiry is presented.

    A practice with a follow-up meeting post death (FUMPD) with physician and staff for family members of patients who died in the intensive care unit (ICU) was started as a quality project to improve the support of families in post-ICU bereavement. A quality improvement control was conducted after 4 years. The quality improvement control was made retrospectively as an anonymous non-coded questionnaire. Part A related to the FUMPD. Part B inquired if we could contact the family member again for a research project to evaluate family support post-ICU bereavement. The questionnaires were sent to 84 family members of 56 deceased patients. Part A: 46 out of 84 family members answered and had attended a FUMPD. Ninety-one percent of the family members thought that we should continue to offer FUMPD. Seventy-eight percent were satisfied with their meeting. Eighty percent felt that they understood the cause of death. The majority wanted the meeting to take place within 6 weeks of death. Ninety-one percent rated the physician as important to be present at the meeting. The social worker was rated more important to attend the meeting than the assistant nurse. Ninety-one percent wanted to discuss the cause of death.Part B: 54 out of 84 family members answered. Twenty out of 54 did not want us to contact them again. A routine with a Follow-Up Meeting Post Death with the ICU team for the families of the patients who die in the ICU is appreciated. The presence of the physician is important. © 2014 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    'Biofiltration systems can be used to treat volatile organic compounds (VOCs); however, the systems are poorly understood and are currently operated as black boxes. Common operational problems associated with biofilters include fouling, deactivation, and overgrowth, all of which make biofilters ineffective for continuous, long-term use. The objective of this investigation is to develop generic methods for long-term stable operation, in particular by using selective limitation of supplemental nutrients while maintaining high activity and the ability to regenerate biofilter activity. As part of this effort, the authors will provide a deeper fundamental understanding of the important biological and transport mechanisms in biodestruction of sparingly soluble VOCs and will extend this engineering approach and developed mathematical models to two additional systems of high-priority environmental management (EM) relevance-direct degradation and cometabolic degradation of priority pollutants such as BTEX (benzene, toluene, ethylbenzene, and xylene) and TCE (trichioroethylene), respectively. Preliminary results indicate that the author can control overgrowth of the biofilm while sustaining high degradation rates and develop basic predictive models that elucidate mass transfer and kinetic limitations in this system for alkanes. The alkanes are degraded into CO, and waterwith minimal biomass (due to the methodology proposed). This system will be used to test and model additional supplemental nutrient feeding strategies as well as methods to increase the fundamental driving forces by modification of the system. Models will be extended to non-steady-state, long-term operation. The author will examine the nature of the mixed microbial community in the VOC-degrading biofilm and test for new degradative activities. He will use cosolvents with surfactant properties to enhance hydrocarbon solubility in the biofilm and evaluate their impact on mass transfer and reaction rate in an

    "Working landscapes" is the concept of fostering effective ecosystem stewardship and conservation through active human presence and management and integrating livestock, crop, and timber production with the provision of a broad range of ecosystem services at the landscape scale. Based on a statewide survey of private landowners of "working" forests and rangelands in California, we investigated whether owners who are engaged in commercial livestock or timber production appreciate and manage biodiversity and ecosystem services on their land in different ways than purely residential owners. Both specific uses and management practices, as well as underlying attitudes and motivations toward biodiversity and ecosystem services, were assessed. Correlation analysis showed one bundle of ecosystem goods and services (e.g., livestock, timber, crops, and housing) that is supported by some landowners at the community level. Another closely correlated bundle of biodiversity and ecosystem services includes recreation, hunting/fishing, wildlife habitat, and fire prevention. Producers were more likely to ally with the first bundle and residential owners with the second. The survey further confirmed that cultural ecosystem services and quality-of-life aspects are among the primary amenities that motivate forest and rangeland ownership regardless of ownership type. To live near natural beauty was the most important motive for both landowner groups. Producers were much more active in management for habitat improvement and other environmental goals than residential owners. As the number of production-oriented owners decreases, developing strategies for encouraging environment-positive management by all types of landowners is crucial.

    Road surface temperature forecast is a key component of winter maintenance strategy in many developed countries. Numerical tools exist to help road managers to organize services and consequently to trigger de-icing operations. Forecasting strategies have been commonplace since the 1980s, and often based on numerical models. Traffic is one of the influencing parameters, specifically in urban areas. This work was undertaken to evaluate to which extent an accurate description of traffic might improve numerical model dedicated to road surface temperature forecasting. Two sets of experiments were run to detect and to quantify traffic effects on RST. First one consisted in driving above an infrared radiometer, a pyrgeometer and other atmospheric probes to measure the radiative contribution of a passing vehicle at various speeds. In the second set, an infrared camera was installed on a vehicle in an urban traffic flow. This camera was mounted on the roof and focused the pavement right behind the vehicle ahead, both circulating at the same speed. Infrared thermography indicated a fleeting contribution of traffic to RST. The temperature increase in circulated areas, with respect to uncirculated ones, does not last according to collected measurements. Measurements with atmospheric and radiometric probes provided elements to properly take into account traffic in a numerical model and to appreciate its contribution.

    Full Text Available Active learning has been linked with increased student motivation, engagement and understanding of course material. It promotes deep learning, helping to develop critical thinking and writing skills in students. Less well understood, however, are the responses of international students to active learning. Using social constructivist theory, the purpose of this study is to examine domestic and international student perceptions of active learning introduced into large undergraduate Accounting Information Systems lectures. Several active learning strategies were implemented over one semester and examined through the use of semi-structured interviews as well as pre- and post- implementation surveys. Our results suggest broad improvements for international students in student engagement and understanding of unit material when implementing active learning strategies. Other key implications include international student preference for active learning compared with passive learning styles, and that international students may receive greater benefits from active learning strategies than domestic students due to social factors. Based on these findings this paper proposes that educators should seek to implement active learning to better assist and integrate students of diverse backgrounds.

    Ralph Steinman, an editor at the Journal of Experimental Medicine since 1978, shared the 2011 Nobel Prize in Physiology or Medicine for his discovery of dendritic cells (DCs) and their role in immunity. Ralph never knew. He died of pancreatic cancer on September 30, 3 days before the Nobel announcement. Unaware of his death at the time of their announcement, the Nobel Committee made the unprecedented decision that his award would stand. Ralph was the consummate physician-scientist to the end. After his diagnosis, he actively participated in his 4.5 years of treatments, creating experimental therapies using his own DCs in conjunction with the therapies devised by his physicians, all the while traveling, lecturing, and most of all pursuing new investigations in his laboratory. For 38 years—from his discovery of DCs to his Nobel Prize—Ralph pioneered the criteria and methods used to identify, isolate, grow, and study DCs. He and his colleagues demonstrated that DCs are initiators of immunity and regulators of tolerance. In his most recent studies, Ralph was harnessing the specialized features of DCs to design improved vaccines. The following synopsis describes some of his seminal discoveries. PMID:22216460

    Data are scarce about short-term right ventricular changes in pulmonary hypertension. Two-dimensional knowledge-based reconstruction of the right ventricle with 2D echocardiography (2DKBR) has been shown to be a valid alternative to Cardiac MRI. In this longitudinal study 25 pulmonary hypertension patients underwent 2DKBR of the right ventricle, assessment of NT-proBNP levels and functional class at baseline and after a mean follow-up of 6.1 months. Patients were followed up clinically for a further mean of 8.2 months. The majority of patients had connective tissue disease (CTD) associated pulmonary arterial hypertension (n=15) or chronic thromboembolic pulmonary hypertension (CTEPH; n=6). A total of 15 patients underwent an intervention, either new targeted therapy, escalation of targeted therapy or pulmonary endarterectomy. A total of 10 clinically stable patients were routinely followed up without any change in therapy. There were significant improvements in the right ventricular end-diastolic volume index (111±29 mL/m² vs 100±36 mL/m²; P=.038), end-systolic volume index (72±23 mL/m² vs 61±25 mL/m²; P=.001), and ejection fraction (35±10% vs 40±9%; P=.030). Changes in NT-proBNP levels correlated strongest with changes in end-systolic volume index (r=-.77; P=right ventricle was associated with clinical worsening. In a CTD and CTEPH dominated patient population significant reverse remodeling and improvement of ejection fraction occurred despite a short follow-up and was paralleled by significant changes in NT-proBNP levels. Further right ventricular dilatation was associated with worse clinical outcome. 2DKBR is a feasible substitute for Cardiac MRI to follow-up right ventricular indices in pulmonary hypertension. © 2017, Wiley Periodicals, Inc.

    The use of implants that allow chronic electrical stimulation and recording in the brain of human patients is currently limited by a series of events that cause the deterioration over time of both the electrode surface and the surrounding tissue. The main reason of failure is the tissue inflammatory reaction that eventually causes neuronal loss and glial encapsulation, resulting in a progressive increase of the electrode-electrolyte impedance. Here, we describe a new method to create bio-inspired electrodes to mimic the mechanical properties and biological composition of the host tissue. This combination has a great potential to increase the implant lifetime by reducing tissue reaction and improving electrical coupling. Our method implies coating the electrode with reprogrammed neural or glial cells encapsulated within a hydrogel layer. We chose fibrin as a hydrogel and primary hippocampal neurons or astrocytes from rat brain as cellular layer. We demonstrate that fibrin coating is highly biocompatible, forms uniform coatings of controllable thickness, does not alter the electrochemical properties of the microelectrode and allows good quality recordings. Moreover, it reduces the amount of host reactive astrocytes - over time - compared to a bare wire and is fully reabsorbed by the surrounding tissue within 7 days after implantation, avoiding the common problem of hydrogels swelling. Both astrocytes and neurons could be successfully grown onto the electrode surface within the fibrin hydrogel without altering the electrochemical properties of the microelectrode. This bio-hybrid device has therefore a good potential to improve the electrical integration at the neuron-electrode interface and support the long-term success of neural prostheses.

    Cluster randomised controlled trial. Clusters of adolescents (classrooms of 15- to 16-year-olds) in each school were allocated either into a control group or into an intervention group. The interventions consisted of peer cooperation (peer support) and peer interactive learning (observational learning) facilitated through feedback from a dentist (professional support). Three intervention sessions with preselected pairs of adolescents were delivered in the first three weeks. Gender, family socio-economic status (baseline) and different social-cognitive domain variables (baseline, six, and 12 months) were assessed using a questionnaire. Dental plaque levels were the primary outcome measure and they were measured at baseline, after the intervention measured only in the social-cognitive theory-guided group, at six and 12 months. At the six-month follow-up there was a statistically significant difference in means ± SD between the social-cognitive intervention group (27.4 ± 19.4) and the control group (35.1 ± 20.0). At the 12-month follow-up, there was no statistically significant difference in means ± SD between the social-cognitive intervention group (27.4 ± 18.5) and the control group (31.9 ± 17.8). Variations in dental plaque levels at different time periods were explained by the following predictors: family's socio-economic status, social-cognitive domain variables, group affiliation and baseline plaque levels. Social-cognitive theory-guided interventions improved oral self-care of adolescents in the short term. This improvement lasted only for five months after the intervention was discontinued.

    Sodium nitroprusside (SNP) enhanced CPR (SNPeCPR) demonstrates increased vital organ blood flow and survival in multiple porcine models. We developed a new, coronary occlusion/ischemia model of prolonged resuscitation, mimicking the majority of out-of-hospital cardiac arrests presenting with shockable rhythms. SNPeCPR will increase short term (4-h) survival compared to standard 2015 Advanced Cardiac Life Support (ACLS) guidelines in an ischemic refractory ventricular fibrillation (VF), prolonged CPR model. Sixteen anesthetized pigs had the ostial left anterior descending artery occluded leading to ischemic VF arrest. VF was untreated for 5min. Basic life support was performed for 10min. At minute 10 (EMS arrival), animals received either SNPeCPR (n=8) or standard ACLS (n=8). Defibrillation (200J) occurred every 3min. CPR continued for a total of 45min, then the balloon was deflated simulating revascularization. CPR continued until return of spontaneous circulation (ROSC) or a total of 60min, if unsuccessful. SNPeCPR animals received 2mg of SNP at minute 10 followed by 1mg every 5min until ROSC. Standard ACLS animals received 0.5mg epinephrine every 5min until ROSC. Primary endpoints were ROSC and 4-h survival. All SNPeCPR animals (8/8) achieved sustained ROSC versus 2/8 standard ACLS animals within one hour of resuscitation (p=0.04). The 4-h survival was significantly improved with SNPeCPR compared to standard ACLS, 7/8 versus 1/8 respectively, p=0.0019. SNPeCPR significantly improved ROSC and 4-h survival compared with standard ACLS CPR in a porcine model of prolonged ischemic, refractory VF cardiac arrest. Copyright © 2016 Elsevier Ireland Ltd.

    We investigated the influence of slight thinning (percentage of woods: 16.6%, basal area: 9.3%) on landscape appreciation and the psychological restorative effect of an on-site setting by exposing respondents to an ordinarily managed coniferous woodland. The experiments were conducted in an experimental plot in the same coniferous woodland in May (unthinned) and October 2013 (thinned). The respondents were the same 15 individuals for both experiments. Respondents were individually exposed to the enclosed plot and the forest-view plot within the same tent for 15 min. In both sessions, respondents were required to answer three questionnaires measuring their mood (Profile of Mood States), emotion (Positive and Negative Affect Schedule), and feeling of restoration (Restorative Outcome Scale) to investigate the psychological restorative effect before and after the experiment. They completed two other questionnaires measuring appreciation for the environment (Semantic Differential) and the restorative properties of the environment (Perceived Restorativeness Scale) following the experiments. We first analyzed the difference in landscape appreciation between the unthinned and thinned conditions. We did not find any statistical difference in appreciation for the environment (Semantic Differential) or the restorative properties of the environment (Perceived Restorativeness Scale); rather, we found that weather conditions had a primary influence on landscape appreciation. With respect to the psychological restorative effect, a two-way repeated analysis of valiance (ANOVA) revealed significant main effects for a selection of indices, depending on the presence or absence of thinning. However, multiple comparison analyses revealed that these effects seemed to be due to the difference in the experimental experience rather than the presence or absence of thinning. In conclusion, the effect of the slight thinning of the managed coniferous forest was too weak to be reflected in the

    To examine and critique how the phases of the 4D cycle (Discovery, Dream, Design, and Destiny) of appreciative inquiry are implemented in a healthcare context. Appreciative inquiry is a theoretical research perspective, an emerging research methodology and a world view that builds on action research, organizational learning, and organizational change. Increasing numbers of articles published provide insights and learning into its theoretical and philosophical underpinnings. Many articles describe appreciative inquiry and the outcomes of their studies; however, there is a gap in the literature examining the approaches commonly used to implement the 4D cycle in a healthcare context. A methodological review following systematic principles. A methodological review was conducted including articles from the inception of appreciative inquiry in 1986 to the time of writing this review in November, 2011. Key database searches included CINAHL, Emerald, MEDLINE, PubMed, PsycINFO, and Scopus. A methodological review following systematic principles was undertaken. Studies were included if they described in detail the methods used to implement the 4D cycle of appreciative inquiry in a healthcare context. Nine qualitative studies met the inclusion criteria. Results highlighted that appreciative inquiry application is unique and varied between studies. The 4D phases were not rigid steps and were adapted to the setting and participants. Overall, participant enthusiasm and commitment were highlighted suggesting appreciative inquiry was mostly positively perceived by participants. Appreciative inquiry provides a positive way forward shifting from problems to solutions offering a new way of practicing in health care and health research. © 2012 Blackwell Publishing Ltd.

    Ethics rounds are one way to support healthcare personnel in handling ethically difficult situations. A previous study in the present project showed that ethics rounds did not result in significant changes in perceptions of how ethical issues were handled, that is, in the ethical climate. However, there was anecdotal evidence that the ethics rounds were viewed as a positive experience and that they stimulated ethical reflection. The aim of this study was to gain a deeper understanding of how the ethics rounds were experienced and why the intervention in the form of ethics rounds did not succeed in improving the ethical climate for the staff. An exploratory and descriptive design with a qualitative approach was adopted, using individual interviews. A total of 11 healthcare personnel, working in two different psychiatry outpatient clinics and with experience of participating in ethics rounds, were interviewed. The study was based on informed consent and was approved by one of the Swedish Regional Ethical Review Boards. The participants were generally positive about the ethics rounds. They had experienced changes by participating in the ethics rounds in the form of being able to see things from different perspectives as well as by gaining insight into ethical issues. However, these changes had not affected daily work. A crucial question is whether or not increased reflection ability among the participants is a good enough outcome of ethics rounds and whether this result could have been measured in patient-related outcomes. Ethics rounds might foster cooperation among the staff and this, in turn, could influence patient care. By listening to others during ethics rounds, a person can learn to see things from a new angle. Participation in ethics rounds can also lead to better insight concerning ethical issues. © The Author(s) 2014.

    There are two problems of the LS (Least Squares)+AR (AutoRegressive) model in polar motion forecast: the inner residual value of LS fitting is reasonable, but the residual value of LS extrapolation is poor; and the LS fitting residual sequence is non-linear. It is unsuitable to establish an AR model for the residual sequence to be forecasted, based on the residual sequence before forecast epoch. In this paper, we make solution to those two problems with two steps. First, restrictions are added to the two endpoints of LS fitting data to fix them on the LS fitting curve. Therefore, the fitting values next to the two endpoints are very close to the observation values. Secondly, we select the interpolation residual sequence of an inward LS fitting curve, which has a similar variation trend as the LS extrapolation residual sequence, as the modeling object of AR for the residual forecast. Calculation examples show that this solution can effectively improve the short-term polar motion prediction accuracy by the LS+AR model. In addition, the comparison results of the forecast models of RLS (Robustified Least Squares)+AR, RLS+ARIMA (AutoRegressive Integrated Moving Average), and LS+ANN (Artificial Neural Network) confirm the feasibility and effectiveness of the solution for the polar motion forecast. The results, especially for the polar motion forecast in the 1-10 days, show that the forecast accuracy of the proposed model can reach the world level.

    Aim of the study Curcuma comosa extract and some purified compounds from this plant have been reported to have estrogenic-like effects, and estrogen improves learning in some animals and potentially in postmenopausal women; therefore, this study tested the hypothesis that Curcuma comosa and estrogen have similar beneficial effects on spatial learning and memory. Materials and methods Curcuma comosa hexane extract, containing 0.165 mg of (4E,6E)-1,7-diphenylhepta-4,6-dien-3-one per mg of the crude extract, was orally administered to ovariectomized Wistar rats at the doses of 250 or 500 mg/kg body weight. 17β-estradiol (10 μg/kg body weight, subcutaneously) was used as a positive control. Thirty days after the initiation of treatment, animals were tested in a Morris water maze for spatial learning and memory. They were re-tested every 30 days and a final probe trial was run on day 119. Results Compared to control rats, OVX rats displayed significant memory impairment for locating the platform in the water maze from day 67 after the surgery, onward. In contrast, OVX rats treated with either Curcuma comosa or estrogen were significantly protected from this decline in cognitive function. Further, the protection of cognitive effects by Curcuma comosa was larger at higher dose. Conclusions These results suggest that long-term treatment with Curcuma comosa has beneficial effects on learning and memory function in rats. PMID:20420894

    Since quality control issues for vitrified waste are defined mainly with the focus on the transport and interim storage of the waste rather than the long-term safety of geological disposal, they do not cover inventories of long-lived nuclides that are of most interest in the safety assessment of geological disposal. Therefore, we suggest a flow chart for the assessment of inventories of long-lived nuclides in the vitrified waste focusing on the measured values. This includes an indirect assessment with indicative nuclides that have been already measured in the returned vitrified wastes from abroad. In order to apply this flow chart for commercial operation, its applicability should be examined for cases with a variation in burn-up history and with an uncertainty associated with carry-over fraction at reprocessing. We started an R and D program to examine the applicability as well as to improve the reliability of the nuclide generation/decay code and the nuclear data library using liquid waste from spent fuel with a clear irradiation history. To solve the issue of quality control for vitrified waste, a comprehensive study is needed in aspects not only of geological disposal field but also of operation of a nuclear power plant, reprocessing of spent fuel and vitrification of liquid waste. This study is a pioneering study conducted to integrate them. (author)

    Liquid-based cytology (LBC) has replaced conventional smear assessment in many centers over recent years. In our laboratory this transfer took place in 1999. At that time we performed a split sample study comparing the conventional method of cervical smear evaluation with the ThinPrep system. This split sample study identified a dramatic improvement in specimen adequacy with LBC. While 11% of conventional preparations were reported as unsatisfactory and almost 9% were reported as suboptimal, evaluation of the same cases using LBC saw this combined figure reduced to 2.3%. AIM: To evaluate whether this dramatic fall in unsatisfactory smears has been maintained with the use of LBC. The database for all smears reported for 2005 (100% LBC) was interrogated. The number of unsatisfactory reports was calculated. The reason for an unsatisfactory report was recorded for each case. The overall unsatisfactory rate was compared with that reported in the 1999 split sample study. A total of 41,312 smear tests were reported in 2005. 1,342 (3.25%) were reported as unsatisfactory. Our findings support the ongoing value of LBC in a routine cervical screening laboratory in terms of continuing to maintain a low rate of unsatisfactory smears.

    Aging is accompanied by a decrease in aerobic capacity. Therefore, physical training has been recommended to soften the effects of advancement age. The aim of this study was to assess the effects of a short-term water-based aerobic training on resting heart rate (HR rest ), heart rate corresponding to anaerobic threshold (HR AT ), peak heart rate (HR peak ), percentage value of HR AT in relation to HR peak and test duration (TD) of mature women. Twenty-two women (65.91 ± 4.83 years) were submitted to a five-week water-based interval aerobic training. Aerobic capacity parameters were evaluated through an aquatic incremental test. After training, there was an increase in TD (16%) and HR AT percentage in relation to HR peak (4.68%), and a reduction of HR rest (9%). It is concluded that a water-based aerobic interval training prescribed through HR AT of only five weeks is able to promote improvements in aerobic capacity of mature women.

    Full Text Available Objective. The purpose of this work is to compare the long-term survival between a control group with mostly D1 lymphadenectomy and a study group with mostly D2 lymphadenectomy. Materials and Methods. We analyzed consecutive cases operated by a single surgeon performing mostly D2 lymphadenectomy and a control group of consecutive gastric cancer patients operated by a group of surgeons, performing mostly D1 lymphadenectomy, in a period when D2 lymphadenectomy was not the standard and was introduced as a new technique in our center. Results. We found 30,56% D2 lymphadenectomy in the control groups and 85,1% in the study group. At a five years interval from surgery the control group had no survivors, while the study group had 8 (20% survivors. Conclusions. The spleen and pancreas preserving D2 lymphadenectomy done by experienced surgeons, according to the current guidelines in order to select operable patients improves the overall survival of such gastric cancer patients.

    This study investigated the effect of 5 days of controlled short-term heat acclimation (STHA) on the determinants of endurance performance and 5-km performance in runners, relative to the impairment afforded by moderate heat stress. A control group (CON), matched for total work and power output (2.7 W·kg -1 ), differentiated thermal and exercise contributions of STHA on exercise performance. Seventeen participants (10 STHA, 7 CON) completed graded exercise tests (GXTs) in cool (13 °C, 50% relative humidity (RH), pre-training) and hot conditions (32 °C, 60% RH, pre- and post-training), as well as 5-km time trials (TTs) in the heat, pre- and post-training. STHA reduced resting (p = 0.01) and exercising (p = 0.04) core temperature alongside a smaller change in thermal sensation (p = 0.04). Both groups improved the lactate threshold (LT, p = 0.021), lactate turnpoint (LTP, p = 0.005) and velocity at maximal oxygen consumption (vV̇O 2max ; p = 0.031) similarly. Statistical differences between training methods were observed in TT performance (STHA, -6.2(5.5)%; CON, -0.6(1.7)%, p = 0.029) and total running time during the GXT (STHA, +20.8(12.7)%; CON, +9.8(1.2)%, p = 0.006). There were large mean differences in change in maximal oxygen consumption between STHA +4.0(2.2) mL·kg -1 ·min -1 (7.3(4.0)%) and CON +1.9(3.7) mL·kg -1 ·min -1 (3.8(7.2)%). Running economy (RE) deteriorated following both training programmes (p = 0.008). Similarly, RE was impaired in the cool GXT, relative to the hot GXT (p = 0.004). STHA improved endurance running performance in comparison with work-matched normothermic training, despite equality of adaptation for typical determinants of performance (LT, LTP, vV̇O 2max ). Accordingly, these data highlight the ergogenic effect of STHA, potentially via greater improvements in maximal oxygen consumption and specific thermoregulatory and associated thermal perception adaptations absent in normothermic training.

    -ANN model (without regime classification) is adopted as a reference model. Both models are evaluated in terms of Improvement over Persistence on the Mean Square Error basis (IoP%) when predicting horizons form 1 time-step to 5. The case of a wind farm located in the complex terrain of Alaiz (north of Spain) has been considered. Three years of available power output data with a hourly resolution have been employed: two years for training and validation of the model and the last year for assessing the accuracy. Results showed that the RS-ANN overcame the single-ANN model for one step-ahead forecasts: the overall IoP% was up to 8.66% for the RS-ANN model (depending on the gradient criterion selected to consider the ramp regime triggered) and 6.16% for the single-ANN. However, both models showed similar accuracy for larger horizons. A locally-weighted evaluation during ramp events for one-step ahead was also performed. It was found that the IoP% during ramps-up increased from 17.60% (case of single-ANN) to 22.25% (case of RS-ANN); however, during the ramps-down events this improvement increased from 18.55% to 19.55%. Three main conclusions are derived from this case study: It highlights the importance of considering statistical models capable of differentiate several regimes showed by the output power time series in order to improve the forecasting during extreme events like ramps. On-line regime classification based on available power output data didn't seem to contribute to improve forecasts for horizons beyond one-step ahead. Tacking into account other explanatory variables (local wind measurements, NWP outputs) could lead to a better understanding of ramp events, improving the regime assessment also for further horizons. The RS-ANN model slightly overcame the single-ANN during ramp-down events. If further research reinforce this effect, special attention should be addressed to understand the underlying processes during ramp-down events.

    Excellent memory, extraordinary intelligence, great academic achievement, and successful career are the dreams of every individual in this era of competition and professionalism. A good memory power acts as a catalyst in all walks of life, be it academic success or maintenance of personal relationships. It is observed that an average man uses only 10% of his natural memory. Remaining 90% is left unused in a haphazard manner. As per the American psychologist Carl Emil Seashore, if one is alert and makes systematic attempts to awaken and use the natural memory properly, his/her natural memory would be activated creatively and would offer benefits of higher order. A comparative study was conducted comprising 90 subjects to know the efficacy of Medhya Rasayana and Yogic practices in short-term memory of school-going children. The study was conducted over a period of 3 months. It was an open, prospective, and randomized clinical study. The subjects of group A formed the control group and they were observed silently for 3 months without any intervention. The subjects in group B were administered with Choorna (powder) of four Medhya Rasayanas, Mandukaparni (Centella asiatica Linn.), Yashtimadhu (Glycyrrhiza glabra Linn.), Guduchi [Tinospora cordifolia (Willd.) Miers ex Hook. f. and Thoms.], and Sankhapushpi (Convolvulus pluricaulis Choisy), at a dose of 2 g twice daily with milk. Subjects belonging to group C were advocated regular Yogic practices of Asanas, Pranayama, and Dhyana. Further study revealed that among the three groups, group B treated with Medhya Rasayana showed highly significant and most effective changes with respect to objective parameters in the tests, i.e. (1) short-term memory test pictures and (2) serial recall effects test using memory scope. Among the three groups, group C treated with Yogic practices showed highly significant and most effective changes with respect to subjective and objective parameters in mini mental status scale i.e. test 3.

    This study provides results of a treatment option for patients with failed primary glaucoma drainage device. The study aimed to describe and evaluate the long-term intraocular pressure control and complications of a new technique joining a second glaucoma drainage device directly to an existing glaucoma drainage device termed 'piggyback drainage'. This is a retrospective, interventional cohort study. Eighteen eyes of 17 patients who underwent piggyback drainage between 2004 and 2013 inclusive have been studied. All patients had prior glaucoma drainage device with uncontrolled intraocular pressure. The piggyback technique involved suturing a Baerveldt (250 or 350 mm) or Molteno3 glaucoma drainage device to an unused scleral quadrant and connecting the silicone tube to the primary plate bleb. Failure of intraocular pressure control defined as an intraocular pressure greater than 21 mmHg on maximal therapy on two separate occasions or further intervention to control intraocular pressure. The intraocular pressure was controlled in seven eyes (39%) at last follow-up with a mean follow-up time of 74.2 months. The mean preoperative intraocular pressure was 27.1 mmHg (95% confidence interval 23.8-30.3) compared with 18.4 mmHg (95% confidence interval 13.9-22.8) at last follow-up. The mean time to failure was 57.1 months (95% confidence interval 32.2-82), and the mean time to further surgery was 72.3 months (95% confidence interval 49.9-94.7). Lower preoperative intraocular pressure was associated with longer duration of intraocular pressure control (P = 0.048). If the intraocular pressure was controlled over 2 years, it continued to be controlled over the long term. Two eyes (11%) experienced corneal decompensation. Piggyback drainage represents a viable surgical alternative for the treatment of patients with severe glaucoma with failing primary glaucoma drainage device, particularly in those at high risk of corneal decompensation. © 2017 Royal Australian and New Zealand

    To investigate the impact of a multicomponent exercise program on anthropometry, physical function, and physical activity on older adults living in long-term nursing homes (LTNH), we conducted a randomized controlled trial involving 112 participants aged 84.9 ± 6.9 years. Participants were randomly assigned to an intervention (IG) or control group (CG). The IG participated in a 3-month multicomponent exercise intervention focused on strength, balance, stretching exercises, and walking recommendations. Subjects in the CG participated in routine activities. Analyses of outcome parameters were performed in the entire sample and in two subgroups, classified according to participants' physical function score at baseline. The group-by-time interaction, favoring the IG, was significant for the entire sample and for the participants in the low physical function subgroup for the following parameters: waist circumference, 30-s chair-stand, arm-curl, 8-ft timed up-and-go, SPPB score, gait speed, and Berg scale (p < .05). In participants with higher physical function at baseline, significant group-by-time interaction was observed in the SPPB score and Berg scale (p < .05). When differences were analyzed within groups, the IG maintained or improved in all assessed parameters, while participants in the CG showed a marked decline. Our study showed that a multicomponent exercise program is effective for older people living in LTNH. This is especially relevant in those with lower physical function scores. The lower efficacy of the program in participants with better function might be due to the insufficient exercise demands of our intervention for more fit residents. Future studies should analyze the effects of programs with higher intensities in older people with intermediate to high physical function. Copyright © 2018 Elsevier Inc. All rights reserved.

  6. Incorporating technology buying behaviour into UK-based long term domestic stock energy models to provide improved policy analysis

    International Nuclear Information System (INIS)

    Lee, Timothy; Yao, Runming

    2013-01-01

    The UK has a target for an 80% reduction in CO 2 emissions by 2050 from a 1990 base. Domestic energy use accounts for around 30% of total emissions. This paper presents a comprehensive review of existing models and modelling techniques and indicates how they might be improved by considering individual buying behaviour. Macro (top-down) and micro (bottom-up) models have been reviewed and analysed. It is found that bottom-up models can project technology diffusion due to their higher resolution. The weakness of existing bottom-up models at capturing individual green technology buying behaviour has been identified. Consequently, Markov chains, neural networks and agent-based modelling are proposed as possible methods to incorporate buying behaviour within a domestic energy forecast model. Among the three methods, agent-based models are found to be the most promising, although a successful agent approach requires large amounts of input data. A prototype agent-based model has been developed and tested, which demonstrates the feasibility of an agent approach. This model shows that an agent-based approach is promising as a means to predict the effectiveness of various policy measures. - Highlights: ► Long term energy models are reviewed with a focus on UK domestic stock models. ► Existing models are found weak in modelling green technology buying behaviour. ► Agent models, Markov chains and neural networks are considered as solutions. ► Agent-based modelling (ABM) is found to be the most promising approach. ► A prototype ABM is developed and testing indicates a lot of potential.

  7. Daryl Lindsay and the appreciation of indigenous art: no mere collection of interesting curiosities

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available In an era when the acceptance of Indigenous art within our galleries is assumed confidently as self-evident, it is easy to overlook how such a remarkable transformation occurred almost within the space of a decade. Even more misunderstood is the prominent role Daryl Lindsay played in the early acceptance and legitimisation of Australian indigenous art. Within months of becoming director of the NGV, Lindsay prepared a major exhibition of primitive art, including Australian indigenous works, an event that became the defining catalyst for a cultural shift towards indigenous art. In the early 1960s, in the influential role of chair of the Commonwealth Art Advisory Board, Lindsay advocated for the inclusion of Australian Aboriginal art, chosen for aesthetic merit as a dedicated collecting stream in the future NGA. It was a decisive objective, and one that was a central tenet of his vision for Australian art. Yet it is clear that Lindsays role in encouraging the re-evaluation of Australian Indigenous art remains poorly understood within the field of Australian gallery practice. Even within recent years, art historians have misattributed later events as being the catalyst for change, either positioning Lindsay as a reactionary late in his term as director, or placing him outside the formative years of the shift in attitude altogether. This paper explores Lindsays young adult experiences in Central Australia, the backdrop for his empathy with Australian Indigenous culture, and the remarkable shift in Australian Art Museum practice undertaken during his directorship that saw Indigenous artefacts exhibited and appreciated for their artistic merit.

  8. The Meaning of the Past: The Perception and Appreciation of History Among Dutch Genealogists

    Directory of Open Access Journals (Sweden)

    Kees Ribbens

    2006-03-01

    Full Text Available Genealogy is a popular hobby in the Netherlands nowadays. This article presents findings from a survey of 192 members of the Dutch Genealogical Society. This research focuses on the meanings genealogists attach to the past and on the emotions and activities connected to this. Dutch genealogists associate past and history with positive matters. They perceive the past as a source of knowledge and as a beneficial contrast to the present. They show a specific interest in the period between 1500 and 1900, the respondent's place of residence and region, his or her family life and the life cycle. Most of the genealogists are looking for those sources of information that reinforce an emotional connectedness to the past. Their appreciation of historical knowledge shows the continuity that they experience between the present and the past. Nevertheless many genealogists clearly consider the past as different, as a contrast to the present. Judging by their own definitions of terms, genealogists have more interest for 'past' in the sense of what is close by and small-scale, and therefore almost directly accessible, than for 'history' in the sense of the authorized knowledge from the dominant historical canon. Genealogists are a diverse group. Particularly the level of education and the connectedness with the region and place of residence influence the way in which history is perceived. Gender seems to play only a limited role here. Genealogists with higher levels of education have a broader interest, particularly with respect to larger geographical areas and to topics concerning society at large. Education and a geographical separation with the family past seem to stimulate a stronger development of the traditional notion of historical consciousness in addition to an interest in family history.

    Interfacing-system loss-of-coolant-accident (ISLOCA) has been identified as the most hazardous accident scenario in the typical PWR plants. The present study as an effort to improve the knowledge of the source term to the environment during ISLOCA focuses on an improvement of the estimation method. The improvement was performed to take into account an effect of broken pipeline and auxiliary building structures relevant to ISLOCA. An estimation of the source term to the environment was for the OPR-1000 plants by MELOCR code version 1.8.6. The key features of the source term showed that the massive amount of fission products departed from the beginning of core degradation to the vessel breach. The release amount of fission products may be affected by the broken pipeline and the auxiliary building structure associated with release pathway.

  10. Self-compassion moderates body comparison and appearance self-worth's inverse relationships with body appreciation.

    2015-09-01

    Although research on positive body image has increased, little research has explored which variables protect body appreciation during body-related threats. Self-compassion may be one such variable. Individuals high in self-compassion are mindful, kind, and nurturing toward themselves during situations that threaten their adequacy, while recognizing that being imperfect is part of "being human." In this study, we investigated whether two body-related threats (i.e., body comparison and appearance contingent self-worth) were more weakly related to body appreciation when self-compassion was high among an online sample of 263 women (Mage=35.26, SD=12.42). Results indicated that self-compassion moderated the inverse relationships between body related threats and body appreciation. Specifically, when self-compassion was very high, body comparison and appearance contingent self-worth were unrelated to body appreciation. However, when self-compassion was low, these relationships were strong. Self-compassion, then, may help preserve women's body appreciation during body-related threats. Copyright © 2015 Elsevier Ltd.

    Andrew, Rachel; Tiggemann, Marika; Clark, Levina

    2016-09-01

    This study examined a range of predictors, based on previous theoretical models, of positive body image in young adult women. Participants were 266 women who completed an online questionnaire measuring body appreciation, activity participation, media consumption, perceived body acceptance by others, self-compassion, and autonomy. Potential mechanisms in predicting body appreciation assessed were self-objectification, social appearance comparison, and thin-ideal internalisation. Results indicated that greater perceived body acceptance by others and self-compassion, and lower appearance media consumption, self-objectification, social comparison, and thin-ideal internalisation were related to greater body appreciation. An integrated model showed that appearance media (negatively) and non-appearance media and self-compassion (positively) were associated with lower self-objectification, social comparison, and thin-ideal internalisation, which in turn related to greater body appreciation. Additionally, perceived body acceptance by others was directly associated with body appreciation.

It appears that the rise in RMB value is caused by supply exceeding demand in China's foreign exchange market; however, intrinsically it is due to the asymmetry in RMB exchange rate formation mechanism. The export tax rebates policy implemented by Chinese government is one of the leading causes of the asymmetry. This study constructs a transmission model between export tax rebates and foreign exchange rates, and applies the Granger Test to validate the causality between kernel variables based on correlative data from 1994-2011, and uses the error correction method to analyze the quantified relations of kernel variables, and finally gets the contribution rate of export tax rebates to RMB appreciation.

  13. Finding meaning in art: Preferred levels of ambiguity in art appreciation

    Science.gov (United States)

    Jakesch, Martina; Leder, Helmut

    2011-01-01

    Uncertainty is typically not desirable in everyday experiences, but uncertainty in the form of ambiguity may be a defining feature of aesthetic experiences of modern art. In this study, we examined different hypotheses concerning the quantity and quality of information appreciated in art. Artworks were shown together with auditorily presented statements. We tested whether the amount of information, the amount of matching information, or the proportion of matching to nonmatching statements apparent in a picture (levels of ambiguity) affect liking and interestingness. Only the levels of ambiguity predicted differences in the two dependent variables. These findings reveal that ambiguity is an important determinant of aesthetic appreciation and that a certain level of ambiguity is appreciable. PMID:19565431

  15. Sustained long-term improvement with clozapine in schizophrenia Clozapina na esquizofrenia grave: melhora duradoura e sustentada

    Directory of Open Access Journals (Sweden)

    RICARDO DE OLIVEIRA-SOUZA

    1999-03-01

    Full Text Available The present paper reports the long-term use of clozapine in a prospective sample of 46 chronic schizophrenics. In six months, 21 subjects had been excluded for a number of reasons. In four of them the reasons for exclusion were related to lack of response or adverse effects. The median daily clozapine dose was 400 mg in the remaining 25 patients. As a whole, there were remarkable improvements in core dimensions of psychopathology, global cognitive status, and level of functioning. We confirmed that clozapine is effective in a subgroup of schizophrenics with the severest forms of the disease. If tolerated after the first few months it leads to progressive gains in several domains of behavior. Clozapine should be tried in every patient with schizophrenia in whom positive symptoms, disorganization, or bizarre behavior are a matter of incapacitation despite efforts to keep them under control with other drugs.O presente estudo, prospectivo, relata o uso de longo-prazo da clozapina em 46 esquizofrênicos graves, com mais de cinco anos de doença. Com seis meses de uso da droga, 21 indivíduos haviam sido excluídos por diversas razões. Em quatro, a exclusão se deveu a efeitos adversos ou ausência de resposta. A dose mediana de clozapina foi de 400 mg nos demais 25 pacientes. No todo, observamos melhora em dimensões de psicopatologia, estado cognitivo global, e nível funcional. Concluímos que a clozapina é eficaz em um subgrupo de esquizofrênicos com formas graves da doença. Se tolerada depois dos primeiros meses, produz benefícios progressivos em diversos domínios do comportamento. Clozapina deve ser tentada em todo paciente com esquizofrenia incapacitado por sintomas positivos, desorganização, e/ou comportamentos bizarros, que persistem a despeito de esforços para mantê-los sob controle com outras drogas.

    Building on an approach applied to cardiovascular and cancer research, we estimated the economic returns from United Kingdom public- and charitable-funded musculoskeletal disease (MSD) research that arise from the net value of the improved health outcomes in the United Kingdom. To calculate the economic returns from MSD-related research in the United Kingdom, we estimated (1) the public and charitable expenditure on MSD-related research in the United Kingdom between 1970 and 2013; (2) the net monetary benefit (NMB), derived from the health benefit in quality adjusted life years (QALYs) valued in monetary terms (using a base-case value of a QALY of £25,000) minus the cost of delivering that benefit, for a prioritised list of interventions from 1994 to 2013; (3) the proportion of NMB attributable to United Kingdom research; and (4) the elapsed time between research funding and health gain. The data collected from these four key elements were used to estimate the internal rate of return (IRR) from MSD-related research investments on health benefits. We analysed the uncertainties in the IRR estimate using a one-way sensitivity analysis. Expressed in 2013 prices, total expenditure on MSD-related research from 1970 to 2013 was £3.5 billion, and for the period used to estimate the rate of return, 1978-1997, was £1.4 billion. Over the period 1994-2013 the key interventions analysed produced 871,000 QALYs with a NMB of £16 billion, allowing for the net NHS costs resulting from them and valuing a QALY at £25,000. The proportion of benefit attributable to United Kingdom research was 30% and the elapsed time between funding and impact of MSD treatments was 16 years. Our best estimate of the IRR from MSD-related research was 7%, which is similar to the 9% for CVD and 10% for cancer research. Our estimate of the IRR from the net health gain to public and charitable funding of MSD-related research in the United Kingdom is substantial, and justifies the research investments

    2005-12-01

    Full Text Available In this paper I use the concepts “understanding of science” and “appreciation of science” to analyze selected case studies of current science communication in Denmark. The Danish science communication system has many similarities with science communication in other countries: the increasing political and scientific interest in science communication, the co-existence of many different kinds of science communication, and the multiple uses of the concepts of understanding vs. appreciation of science. I stress the international aspects of science communication, the national politico-scientific context as well as more local contexts as equally important conditions for understanding current Danish science communication.

  18. Effect of aging on hedonic appreciation of pleasant and unpleasant odors.

    Directory of Open Access Journals (Sweden)

    Pauline Joussain

    Full Text Available Does hedonic appreciation evolve differently for pleasant odors and unpleasant odors during normal aging? To answer this question we combined psychophysics and electro-encephalographic recordings in young and old adults. A first study showed that pleasant odorants (but not unpleasant ones were rated as less pleasant by old adults. A second study validated this decrease in hedonic appreciation for agreeable odors and further showed that smelling these odorants decreased beta event-related synchronization in aged participants. In conclusion, the study offers new insights into the evolution of odor hedonic perception during normal aging, highlighting for the first time a change in processing pleasant odors.

    We reported on a patient with mild traumatic brain injury (TBI) who showed recovery of an injured cingulum concurrent with improvement of short-term memory, which was demonstrated on follow-up diffusion tensor tractography (DTT). A 55-year-old male patient suffered head trauma resulting from falling from approximately 2 m while working at a construction site. The patient showed mild memory impairment (especially short-term memory impairment) at 3 months after onset: Memory Assessment Scale (global memory: 95 (37%ile), short-term memory: 75 (5%ile), verbal memory: 80 (9%ile) and visual memory: 112 (79%ile)). By contrast, at 2 years after onset, his mild memory impairment had improved to a normal state: Memory Assessment Scale (global memory: 104 (61%ile), short-term memory: 95 (37%ile), verbal memory: 101 (53%ile) and visual memory: 106 (66%ile)). On 3-month DTT, discontinuation of the right anterior cingulum was observed over the genu of the corpus callosum, while on 2-year DTT, the discontinued right anterior cingulum was elongated to the right basal forebrain. In conclusion, recovery of an injured cingulum concurrent with improvement of short-term memory was demonstrated in a patient with mild TBI.

  4. The artful mind meets art history: toward a psycho-historical framework for the science of art appreciation.

    Science.gov (United States)

    Bullot, Nicolas J; Reber, Rolf

    2013-04-01

    Research seeking a scientific foundation for the theory of art appreciation has raised controversies at the intersection of the social and cognitive sciences. Though equally relevant to a scientific inquiry into art appreciation, psychological and historical approaches to art developed independently and lack a common core of theoretical principles. Historicists argue that psychological and brain sciences ignore the fact that artworks are artifacts produced and appreciated in the context of unique historical situations and artistic intentions. After revealing flaws in the psychological approach, we introduce a psycho-historical framework for the science of art appreciation. This framework demonstrates that a science of art appreciation must investigate how appreciators process causal and historical information to classify and explain their psychological responses to art. Expanding on research about the cognition of artifacts, we identify three modes of appreciation: basic exposure to an artwork, the artistic design stance, and artistic understanding. The artistic design stance, a requisite for artistic understanding, is an attitude whereby appreciators develop their sensitivity to art-historical contexts by means of inquiries into the making, authorship, and functions of artworks. We defend and illustrate the psycho-historical framework with an analysis of existing studies on art appreciation in empirical aesthetics. Finally, we argue that the fluency theory of aesthetic pleasure can be amended to meet the requirements of the framework. We conclude that scientists can tackle fundamental questions about the nature and appreciation of art within the psycho-historical framework.

  5. Factors affecting the appreciation generated through applying human factors/ergonomics (HFE) principles to systems of work.

    Science.gov (United States)

    So, R H Y; Lam, S T

    2014-01-01

    This retrospective study examined the levels of appreciation (applause) given by clients to Human Factors/Ergonomic (HFE) specialists after they have modified the systems of work. Thirteen non-academic projects were chosen because the HFE interventions involved changed the way workers work at their workplaces. Companies involved range from multi-national corporations and military organizations with thousands of employees to small trading companies with less than 10 employees. In 5 cases the HFE recommendations were fully adopted and well appreciated. In 4 they were largely ignored and not appreciated, with partial adoption and some appreciation in the other 4 cases. Three factors that predict appreciation were identified: (i) alignment between the benefits HFE can provide and the project's key performance indices; (ii) awareness of HFE among the client's senior management; and (iii) a team organization appropriate for applying HFE recommendations. Having an HFE specialist on the client's side can greatly increase levels of appreciation, but lack of such a specialist will not affect levels of appreciation. A clear contractual requirement for HFE intervention does not promote appreciation significantly, but its absence can greatly reduce levels of appreciation. These relationships are discussed using the Kano's model of quality. Means to generate greater appreciation of the benefits of HFE are discussed.

    Anderson, Niall; Ozakinci, Gozde

    2018-03-27

    Long-term conditions may negatively impact multiple aspects of quality of life including physical functioning and mental wellbeing. The rapid systematic review aimed to examine the effectiveness of psychological interventions to improve quality of life in people with long-term conditions to inform future healthcare provision and research. EBSCOhost and OVID were used to search four databases (PsychInfo, PBSC, Medline and Embase). Relevant papers were systematically extracted by one researcher using the predefined inclusion/exclusion criteria based on titles, abstracts, and full texts. Randomized controlled trial psychological interventions conducted between 2006 and February 2016 to directly target and assess people with long-term conditions in order to improve quality of life were included. Interventions without long-term condition populations, psychological intervention and/or patient-assessed quality of life were excluded. From 2223 citations identified, 6 satisfied the inclusion/exclusion criteria. All 6 studies significantly improved at least one quality of life outcome immediately post-intervention. Significant quality of life improvements were maintained at 12-months follow-up in one out of two studies for each of the short- (0-3 months), medium- (3-12 months), and long-term (≥ 12 months) study duration categories. All 6 psychological intervention studies significantly improved at least one quality of life outcome immediately post-intervention, with three out of six studies maintaining effects up to 12-months post-intervention. Future studies should seek to assess the efficacy of tailored psychological interventions using different formats, durations and facilitators to supplement healthcare provision and practice.

  9. Short-term variations in core surface flow resolved from an improved method of calculating observatory monthly means

    Science.gov (United States)

    Olsen, Nils; Whaler, Kathryn A.; Finlay, Christopher C.

    2014-05-01

    Monthly means of the magnetic field measurements taken by ground observatories are a useful data source for studying temporal changes of the core magnetic field and the underlying core flow. However, the usual way of calculating monthly means as the arithmetic mean of all days (geomagnetic quiet as well as disturbed) and all local times (day and night) may result in contributions from external (magnetospheric and ionospheric) origin in the (ordinary, omm) monthly means. Such contamination makes monthly means less favourable for core studies. We calculated revised monthly means (rmm), and their uncertainties, from observatory hourly means using robust means and after removal of external field predictions, using an improved method for characterising the magnetospheric ring current. The utility of the new method for calculating observatory monthly means is demonstrated by inverting their first differences for core surface advective flows. The flow is assumed steady over three consecutive months to ensure uniqueness; the effects of more rapid changes should be attenuated by the weakly conducting mantle. Observatory data are inverted directly for a regularised core flow, rather than deriving it from a secular variation spherical harmonic model. The main field is specified by the CHAOS-4 model. Data from up to 128 observatories between 1997 and 2013 were used to calculate 185 flow models from the omm and rmm, for each possible set of three consecutive months. The full 3x3 (non-diagonal) data covariance matrix was used, and two-norm (least squares) minimisation performed. We are able to fit the data to the target (weighted) misfit of 1, for both omm and rmm inversions, provided we incorporate the full data covariance matrix, and produce consistent, plausible flows. Fits are better for rmm flows. The flows exhibit noticeable changes over timescales of a few months. However, they follow rapid excursions in the omm that we suspect result from external field contamination

    Siegfeldt, Denise V.

    1994-01-01

    This study represents the implementation phase of an organizational development project which was initiated last year in the Management Support Division (MSD) at Langley Research Center to diagnose organizational functioning. As a result of MSD survey data from last year's effort, a Quality Action Team was created to address the responses compiled from the MSD Organizational Assessment Questionnaire and Follow-Up Questionnaire. The team was officially named the MSD Employee Relations Improvement Team (MERIT). MERIT's goal was to analyze major concerns generated by the questionnaires and to present feasible solutions to management which would improve supervisory performance, promote process improvement; and ultimately, lead to a better organization. The team met weekly and was very disciplined in following guidelines needed to ensure a fully functioning team. Several TQM tools were used during the team process, including brainstorming and the cause and effect diagram. One of the products produced by MERIT was a 'report card', more formally known as an upward appraisal system, to evaluate supervisory performance in the division office, its three branches, and in teams. Major areas of emphasis on the 47 item report card were those identified by employees through the previously administered questionnaires as needing to be improved; specifically, training, recognition, teamwork, supervision and leadership, and communication. MERIT created an enlarged and modified version of the report card which enabled scores for each individual supervisor to be recorded on a separate form, along with summary results and employee comments. Report card results have been compiled and fed back to the Division Chief and Assistant Division Chief. These individuals will in turn, feed the results back to the remaining supervisors and the team leaders. Although results differ among supervisors, some similarities exist. Communication generally appears to be adequate, which represents an

  1. Adapting the Body Appreciation Scale-2 for Children: A psychometric analysis of the BAS-2C.

    Science.gov (United States)

    Halliwell, Emma; Jarman, Hannah; Tylka, Tracy; Slater, Amy

    2017-06-01

    Positive body image among adults is related to numerous indicators of well-being. However, no research has explored body appreciation among children. To facilitate our understanding of children's positive body image, the current study adapts and validates the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a) for use with children. Three hundred and forty-four children (54.4% girls) aged 9-11 completed the adapted Body Appreciation Scale-2 for Children (BAS-2C) alongside measures of body esteem, media influence, body surveillance, mood, and dieting. A sub-sample of 154 participants (62.3% girls) completed the questionnaire 6-weeks later to examine stability (test-retest) reliability. The BAS-2C displayed a unidimensional factor structure and evidence of internal consistency, test-retest reliability, and construct, criterion-related, and incremental validity. Additionally, the results suggest adaptive properties of body appreciation for body-related and emotional well-being among children. The BAS-2C could serve as an essential component within research to understand and estimate children's positive body image. Copyright © 2017. Published by Elsevier Ltd.

    The aim of this study was to evaluate the influence of transcranial direct current stimulation targeting the left temporoparietal junction (TPJ) on humor appreciation during a dynamic video rating task. In a within-participants design, we targeted the left TPJ with anodal, cathodal, or no transcranial direct current stimulation, centered at electrode site C3 using a 4×1 targeted stimulation montage. During stimulation, participants dynamically rated a series of six stand-up comedy videos for perceived humor. We measured event-related (time-locked to crowd laughter) modulation of humor ratings as a function of stimulation condition. Results showed decreases in rated humor during anodal (vs. cathodal or none) stimulation; this pattern was evident for the majority of videos and was only partially predicted by individual differences in humor style. We discuss the possibility that upregulation of neural circuits involved in the theory of mind and empathizing with others may reduce appreciation of aggressive humor. In conclusion, the present data show that neuromodulation of the TPJ can alter the mental processes underlying humor appreciation, suggesting critical involvement of this cortical region in detecting, comprehending, and appreciating humor.

    Full Text Available Olive pomace is the solid by-product obtained from the extraction of olive oil revealing serious environmental problems in all Mediterranean countries olive growing. Generally, that pomace can be valued, among others, as a source of organic matter (composting. In this perspective, we have addressed in this work to the quantitive and qualitative characterization (limited to certain physico-chemical parameters of the solid by-product of olive oil extraction in the delegation of Kalaa Kebira (Sousse, Tunisia while appreciating their compostability. The results showed that those olive residues are essentially dry, carbon-rich and CF, low in nitrogen. They can be used as compost by combining them with other available sources of plant originand/or animal such as manure of cattle, sheep or poultry (in varying proportions and responsible of the nature very heterogeneous and the variable quality that can be applied to improve soil fertility and crop productivity.
