Motion can be depicted using literal pictorial devices (representing features present in the real world) and metaphorical pictorial devices (representing features that do not occur in the real world). How are literal and metaphorical pictorial devices used in comic book cover art? We analyzed the pictorial devices used to depict the motion 'running' in 400 Silver Age (1956–1971) and Bronze Age (c. 1970–1985) superhero comic book covers (Frankenhoff & Thompson, 2012).

To inform international research and policy, we conducted a meta-analysis of the experimental literature on pictorial cigarette pack warnings. We systematically searched 7 computerised databases in April 2013 using several search terms. We also searched reference lists of relevant articles. We included studies that used an experimental protocol to test cigarette pack warnings and reported data on both pictorial and text-only conditions. 37 studies with data on 48 independent samples (N=33,613) met criteria. Two independent coders coded all study characteristics. Effect sizes were computed from data extracted from study reports and were combined using random effects meta-analytic procedures. Pictorial warnings were more effective than text-only warnings for 12 of 17 effectiveness outcomes (all pnegative pack attitudes and negative smoking attitudes and (4) more effectively increased intentions to not start smoking and to quit smoking. Participants also perceived pictorial warnings as being more effective than text-only warnings across all 8 perceived effectiveness outcomes. The evidence from this international body of literature supports pictorial cigarette pack warnings as more effective than text-only warnings. Gaps in the literature include a lack of assessment of smoking behaviour and a dearth of theory-based research on how warnings exert their effects. Published by the BMJ Publishing Group Limited.

Given that previous studies demonstrated that smoking-related cues (like cigarette packages) grab the attention of smokers and thereby contribute to craving and tobacco seeking we investigated how pictorial health warnings presented on cigarette packages affect attention allocation towards cigarette packages. The WHO advises the use of pictorial health warnings on cigarette packages. However, at present no experimental studies are available investigating if pictorial warnings modulate incentive properties of cigarette packages. Fifty-nine tobacco smokers and 55 non-smokers performed a visual dot probe task to assess attention allocation towards cigarette packages with and without health warnings. Smokers were divided a priori in a group of light smokers (smokers (≥20 cigarettes/day; n=20). Psychometric measures on anxiety and nicotine craving were administered. Light smokers showed an attentional bias towards packages without pictorial warnings while no effects were observed in the other groups. In heavy smokers attention allocation towards pictorial health warnings was associated with an increase of craving and anxiety. The results have a potential public health perspective as pictorial health warnings might be an effective strategy to reduce attentional bias towards cigarette packages of light smokers, while counterproductive effects in heavy smokers warrant further investigation.

Full Text Available OBJECTIVE: The use of pictorial warning labels on cigarette packages is one of the provisions included in the first ever global health treaty by the World Health Organization against the tobacco epidemic. There is substantial evidence demonstrating the effectiveness of graphic health warning labels on intention to quit, thoughts about health risks and engaging in cessation behaviors. However, studies that address the implicit emotional drives evoked by such warnings are still underexplored. Here, we provide experimental data for the use of pictorial health warnings as a reliable strategy for tobacco control. METHODS: Experiment 1 pre-tested nineteen prototypes of pictorial warnings to screen for their emotional impact. Participants (n = 338 were young adults balanced in gender, smoking status and education. Experiment 2 (n = 63 tested pictorial warnings (ten that were stamped on packs. We employed an innovative set-up to investigate the impact of the warnings on the ordinary attitude of packs' manipulation, and quantified judgments of warnings' emotional strength and efficacy against smoking. FINDINGS: Experiment 1 revealed that women judged the warning prototypes as more aversive than men, and smokers judged them more aversive than non-smokers. Participants with lower education judged the prototypes more aversive than participants with higher education. Experiment 2 showed that stamped warnings antagonized the appeal of the brands by imposing a cost to manipulate the cigarette packs, especially for smokers. Additionally, participants' judgments revealed that the more aversive a warning, the more it is perceived as effective against smoking. CONCLUSIONS: Health warning labels are one of the key components of the integrated approach to control the global tobacco epidemic. The evidence presented in this study adds to the understanding of how implicit responses to pictorial warnings may contribute to behavioral change.

A-type stars are expected to be X-ray dark, yet weak emission has been detected from several objects in this class. We present new Chandra/HRC-I observations of the A5 V star {beta} Pictoris. It is clearly detected with a flux of (9 {+-} 2) Multiplication-Sign 10{sup -4} counts s{sup -1}. In comparison with previous data this constrains the emission mechanism and we find that the most likely explanation is an optically thin, collisionally dominated, thermal emission component with a temperature around 1.1 MK. We interpret this component as a very cool and dim corona, with log L{sub X} /L{sub bol} = -8.2 (0.2-2.0 keV). Thus, it seems that {beta} Pictoris shares more characteristics with cool stars than previously thought.

ABSTRACT: This article examines the use of pictorial illustrations in African language dictionar-ies, with particular reference to items generally included in dictionaries based on Stein's (1991 categories. It argues for the need to include more illustrations of cultural items specific to a par-ticular community and language group in dictionaries. A corpus analytic survey is done to deter-mine if African language dictionaries employ pictorial illustrations and, if so, which items are illus-trated. The results of this survey indicate that only a few African language dictionaries employ pictorial illustrations, even those that do correspond to Stein's categories. Of the dictionaries exam-ined, only one uses illustrations in the form of full-colour photographs, namely of different kinds of cattle, a very important cultural item within that specific community.

The norm of this aims to reduce the negative health effects, protect productive age population and increasing public awareness of the dangers of smoking. Against the background of the norm of the government, the study was intended to determine the perception of active smokers the pictorial health warning labels on packs of cigarettes there. In this study, the method used is descriptive method with qualitative data. Data collected through library research informant interviews, and documentation. The results showed that smokers know their pictorial health warning labels on packs of cigarettes and smokers can understand the meaning of their label. Knowledge smokers against pictorial health warning label does not make the smokers to quit smoking, they continue to smoke because of their experience does not suffer due to take up smoking, and the effects felt far different from what was stated on the packaging that has been made. Thus we can say the perception of smokers tend to deny the existence of the warning label.

This study assessed the effects of pictorial health warning labels (HWLs) and a linked media campaign in Mexico. Cross-sectional data were collected from a population-based sample of 1756 adult smokers, aged 18-55 years, during the initial implementation of pictorial HWLs, which some smokers had seen on cigarette packages while others had seen only the text-based HWLs. Exposure to the campaign and pictorial HWLs was assessed with aided recall methods, and other questions addressed attention and cognitive impact of HWLs, knowledge related to HWL and campaign content, and quit-related thoughts and behaviours. Logistic and linear regression models were estimated to determine associations between key outcomes and intervention exposure. In bivariate and multivariate adjusted models, recall of pictorial HWLs and of the campaign were positively associated with greater attention to and cognitive impact of HWLs, whereas only pictorial HWL exposure was associated with having refrained from smoking due to HWLs. Both recall of pictorial HWLs and of the campaign were independently associated with greater knowledge of secondhand smoke harms and toxic tobacco constituents. Smokers who recalled only the pictorial HWLs were more likely to try to quit than smokers who recalled neither the pictorial HWLs nor the campaign (17% vs 6%, pmedia campaign was associated with independent additive effects on campaign-related knowledge, and it enhanced psychosocial responses to pictorial HWLs.

Full Text Available Background for the Study: Informed consent is a process of obtaining permission from the participant to participate in research. Involving children in a research requires them to give their “assent” for participation. Informed assent is obtained from children even after their guardians have given consent for participation. Studies have shown that children have difficulty understanding the key elements of research process such as right to withdraw from the study or the meaning of “harm” involved in the research process. Further, the studies have also propounded that using child-friendly methods such as using pictures and simple language would facilitate children's understanding. Objectives: In this study, pictorial and verbal assent formats were compared find out which format is suitable for children's understanding of informed assent with respect to research. Methods: A sample of 389 school going children and adolescents of both the gender, ranging from 7 to 16 years were considered for the study. The sample was randomly divided into two groups, where for one group (n = 197, pictorial assent format was administered and another group (n = 192, verbal assent format was administered. The pictorial assent format was developed for the study by the corresponding author. Results and Conclusions: Analysis revealed that there was a significant level of interaction between gender and the two assent formats. Males were able to understand pictorial assent format better compared to the females, whereas females were able to understand verbal assent format better than the males, when age and education were considered as covariates. Further, it was found that as age increases there is better understanding of research processes in both the formats. Hence, while the process of obtaining assent for participation in research, age of child must be considered and with respect to gender differences males tend to prefer pictorial formats whereas females tend to

Diffusion tensor and diffusion weighted imaging. Pictorial mathematics

A new imaging algorithm for the treatment of a second order apparent diffusion tensor, D{sub app}{sup {xi}} is described. The method calls for only mathematics of images (pictorial mathematics) without necessity of eigenvalues/eigenvectors estimation. Nevertheless, it is capable of extracting properties of D{sub app}{sup {xi}} invariant to observation axes. While trace image is an example of images weighted by invariance of the tensor matrix, three dimensional anisotropy (3DAC) contrast represents the imaging method making use to anisotropic direction of tensor ellipsoid producing color coded contrast of exceptionally high anatomic resolution. Contrary to intuition, the processes require only a simple algorithm directly applicable to clinical magnetic resonance imaging (MRI). As a contrast method which precisely represents physical characteristics of a target tissue, invariant D{sub app}{sup {xi}} images produced by pictorial mathematics possess significant potential for a number of biological and clinical applications.

The purpose of this study was to develop the Pictorial Thai Quality of Life (PTQL), having adequate and sufficient construct validity, discriminant power, concurrent validity, and reliability. To develop the Pictorial Thai Quality of Life Test, two samples groups were used in the present study: (1) pilot study samples: 30 samples and (2) survey samples were 672 samples consisting of normal, and psychiatric patients. The developing tests items were collected from a review of the literature in which all the items were based on the WHO definition of Quality of Life. Then, experts judgment by the Delphi technique was used in the first stage. After that a pilot study was used to evaluate the testing administration, and wording of the tests items. The final stage was collected data from the survey samples. The results of the present study showed that the final test was composed 25 items. The construct validity of this test consists of six domains: Physical, Cognitive, Affective, Social Function, Economic and Self-Esteem. All the PTQL items have sufficient discriminant power It was found to be statistically significant different at the. 001 level between those people with mental disorders and normal people. There was a high level of concurrent validity association with WHOQOL-BREF, Pearson correlation coefficient and Area under ROC curve were 0.92 and 0.97 respectively. The reliability coefficients for the Alpha coefficients of the PTQL total test was 0.88. The values of the six scales were from 0.81 to 0:91. The present study was directed at developing an effective psychometric properties pictorial quality of life questionnaire. The result will be a more direct and meaningful application of an instrument to detect the mental health illness poor quality of life in

Preliminary Analyses of Transmedia Adaptations of Pictorial Narratives and Aesthetic Pole Interpretations: Reflections on Theory

Directory of Open Access Journals (Sweden)

Yu-Chai Lai

2015-10-01

Full Text Available Transmedia narratives are a key topic of communication research. Transmedia adaptations occur when a narrator transposes an original work by using various media platforms. Considering pictorial turn, this study employed the intermediality of an animated work that was adapted from an award-winning picture book as an example to propose an analysis for theory building. After examining the literature on transmedia narratives, intermediality, and aesthetic communication, this study proposed analyses for the dimensions of transmedia adaptations of pictorial narratives and aesthetic pole interpretations. Focusing on the three layers of the artistic pole, aesthetic pole, and interactions and effects, this study cited the cases of award-winning picture books and adapted animated works as the basis for reflecting on aesthetic communication. The artistic pole of transmedia adaptation was used as an example of how a narrator employs intermediality by citing the pictures, plot, or art forms from an original work to reinvent structures and then adapts them according to intermediality. If the aesthetic pole views the adapted animated work after reading the picture book or forms an expectation of the adaptation because of intermediality, then when the audience watches the adapted animated work, their imagination could be stimulated by the intermediality (i.e., picture book graphics and scene depictions. For transmedia narrative interaction, the aesthetic pole must “fill blanks” or “negate” to continue to view the adaptation. For filling blanks, because of intermediality, the aesthetic pole must construct an “intracompositional intermediality” to connect with the visual and audio links of the same work or construct “extracompositional intermedialtiy” to associate the original work with the transmedia adaptation. For negation, when viewing the adaptation (i.e., presentation of picture book graphics, added music, or theme song, the aesthetic pole

Pictorial health warnings are more effective than text warnings in enhancing motivation to quit and not to start smoking among youth. In Lebanon, packs still have only a very small text warning. The aim of this study was to evaluate the perceived effectiveness of pictorial health warnings on cigarette packs among Lebanese youth. This was a cross-sectional study including school students (n=1412) aged 13-18 years recruited from 28 schools and university students (n=1217) aged 18-25 years recruited from 7 universities. A variety of warnings were adapted from other countries. In all, 4 warnings were tested among school students and 18 among university students. All pictorial warnings were considered more effective than the current text warning on message-related and impact-related variables, including intentions to quit or not to start smoking among school and university students. Selected examples related to the top-ranked pictorial warnings are: among male non-smoking school students, 81% agreed that the 'lung' warning had more impact on their intentions not to start smoking as compared to 57% for the current text warning (pnegative economic consequences of smoking, and to find that such a warning was effective among specific sociodemographic groups.

[Dyschromatopsias and pictorial art].

Lanthony, P

1991-01-01

The influence of color vision defects on pictorial art was studied using three methods. 1) From a theoretical standpoint, the possibilities of choice of the color-blind painter are determined by the nature of his color perception. Characteristic errors result from the fact that he has to choose between many hues which are different to a normal individual but which all look the same to him. 2) Evaluation of the clinical cases of painters with dyschromatopsias has shown evidence of the following: a) the color-blind painter makes mistakes according to the type of color defect; b) if the color-blind painter makes several copies of the same model, he makes different mistakes at each attempt; c) when several color-blind painters make copies of the same model, they also make different mistakes, even when they suffer from the same type of color vision defect. Preferences for some colored patterns were studied by means of a forced choice procedure and choices of color-blind individuals were often characteristic of their dyschromatopsia. Recent clinical case of acquired dyschromatopsia reported in the literature are discussed, as is a personal case of a painter suffering from tapeto-retinal degeneration. This was a severe dyschromatopsia with a neutral zone in purple (so-called scotpic axis, by Verriest's terminology). The painting of this artist tended to be monochromatic, mainly in green and green-blue colors. 3) Recent studies in art history have shown that only the romantic etcher Meryon was definitively color deficient. The more dubious cases of the Polish painter Grottger and of Eugène Carrière are discussed and conclusions are negative. Among acquired dyschromatopsias, there have been many recent papers devoted to cataract dyschromatopsias, concerning the cases of Rouault, Monet and Mary Cassatt. The hypothesis of a degree of chromatopsia or dyschromatopsia of toxic origin in the case of Van Gogh is also assessed. In conclusion, the problem of the relations between

2013-12-01

This review aims to provide an insight into human learning processes by examining the role of cognitive and emotional unconscious processing in mentally integrating visual and verbal instructional materials. Reviewed literature shows that conscious mental integration does not happen all the time, nor does it necessarily result in optimal learning. Students of all ages and levels of experience cannot always have conscious awareness, control, and the intention to learn or promptly and continually organize perceptual, cognitive, and emotional processes of learning. This review suggests considering the role of unconscious learning processes to enhance the understanding of how students form or activate mental associations between verbal and pictorial information. The understanding would assist in presenting students with spatially-integrated verbal and pictorial instructional materials as a way of facilitating mental integration and improving teaching and learning performance.

Despite the high diagnostic accuracy of CT for appendicitis, numerous pitfalls exist that may result in a misdiagnosis. This pictorial review outlines the potential pitfalls in the CT diagnosis of appendicitis that includes atypical position of the appendix and coexisting pathologies. Various mimickers of appendicitis and clinical dilemmas will be highlighted. Upon completion, the reviewer should have an improved ability to recognise appendicitis mimickers and identify equivocal or atypical findings.

Diogene pictorial drift chamber

Gosset, J.

1984-01-01

A pictorial drift chamber, called DIOGENE, has been installed at Saturne in order to study central collisions of high energy heavy ions. It has been adapted from the JADE internal detector, with two major differences to be taken into account. First, the center-of-mass of these collisions is not identical to the laboratory reference frame. Second, the energy loss and the momentum ranges of the particles to be detected are different from the ones in JADE. It was also tried to keep the cost as small as possible, hence the choice of minimum size and minimum number of sensitive wires. Moreover the wire planes are shifted from the beam axis: this trick helps very much to quickly reject the bad tracks caused by the ambiguity of measuring drift distances (positive or negative) through times (always positive)

Purpose Pictorial health warnings on cigarette packages are a prominent and effective means of communicating the risks of smoking; however, there is little research on effective types of message content and socio-demographic effects. This study tested message themes and content of pictorial warnings in Mexico. Methods Face-to-face surveys were conducted with 544 adult smokers and 528 youth in Mexico City. Participants were randomized to view 5–7 warnings for two of 15 different health effects. Warnings for each health effect included a text-only warning and pictorial warnings with various themes: “graphic” health effects, “lived experience”, symbolic images, and testimonials. Results Pictorial health warnings were rated as more effective than text-only warnings. Pictorial warnings featuring “graphic” depictions of disease were significantly more effective than symbolic images or experiences of human suffering. Adding testimonial information to warnings increased perceived effectiveness. Adults who were female, older, had lower education, and intended to quit smoking rated warnings as more effective, although the magnitude of these differences was modest. Few interactions were observed between socio-demographics and message theme. Conclusions Graphic depictions of disease were perceived by youth and adults as the most effective warning theme. Perceptions of warnings were generally similar across socio-demographic groups. PMID:22362058

Rhombencephalitis: pictorial essay

Directory of Open Access Journals (Sweden)

Líllian Gonçalves Campos

Full Text Available Abstract The term rhombencephalitis refers to inflammatory diseases affecting the hindbrain (brainstem and cerebellum. Rhombencephalitis has a wide variety of etiologies, including infections, autoimmune diseases, and paraneoplastic syndromes. Infection with bacteria of the genus Listeria is the most common cause of rhombencephalitis. Primary rhombencephalitis caused by infection with Listeria spp. occurs in healthy young adults. It usually has a biphasic time course with a flu-like syndrome, followed by brainstem dysfunction; 75% of patients have cerebrospinal fluid pleocytosis, and nearly 100% have an abnormal brain magnetic resonance imaging scan. However, other possible causes of rhombencephalitis must be borne in mind. In addition to the clinical aspects, the patterns seen in magnetic resonance imaging can be helpful in defining the possible cause. Some of the reported causes of rhombencephalitis are potentially severe and life threatening; therefore, an accurate initial diagnostic approach is important to establishing a proper early treatment regimen. This pictorial essay reviews the various causes of rhombencephalitis and the corresponding magnetic resonance imaging findings, by describing illustrative confirmed cases.

The Influence of Emotional State and Pictorial Cues on Perceptual Judgments

2007-10-01

Perspective displays (e.g., CDTI) are commonly used as decision aids in environments characterized by periods of high emotional arousal (e.g., terrain enhanced primary flight displays). However, little attention has been devoted to understanding how emotional state, independently or in conjunction with other perceptual factors (e.g., pictorial depth cues), can impact perceptual judgments. Preliminary research suggests that induced emotional state (positive or negative) adversely impacts size comparisons in perspective displays (Tran & Raddatz, 2006). This study further investigated how size comparisons are affected by emotional state and pictorial depth cues while attenuating the limitations of the Tran & Raddatz (2006) study. Results confirmed that observers do make slower judgments under induced emotional state. However, observers under negative emotional state showed higher sensitivity (d’) and required more evidence to respond that a size difference exists (response bias) than observers under positive emotional state. Implications for display design and human performance are discussed.

Previous spectral studies of circumstallar dust around the nearby, candidate proto-planetary system, Beta Pictoris, has detected only infalling gas. The lack of detectable mass outflow has been critical in the interpretation of the origin of the circumstellar gas and in our understanding of the evolutionary status of the Beta Pictoris system. IUE high-dispersion spectra are presented which show, in addition to infall, the presence of mass outflow, with a maximum observed outflow velocity of -60 km/s, and a corresponding instantaneous outflow rate of 1.1 x 10 to the -14th solar mass/yr, or 1.1 x 10 to the -11th Jupiter mass/yr. This mass outflow rate and terminal velocity are comparable to the magnitudes of mass infall rates and terminal velocities observed from late 1986 through early 1988. The implications of these observations on our understanding of the mechanisms producing infall from the surrounding circumstellar disk are discussed, as are the implications for our understanding of the evolutionary status of the Beta Pic system. 23 refs

Promoting science communication skills in the form of oral presentation through pictorial analogy

2018-04-01

Prospective biology teachers are demanded to have skills in communicating science in the form of oral presentation when someday they teach. However, over-expectation towards biological concept comprehension has led them to lower their participation in class. In such a case, rote learning is standing still to support biological content knowledge delivery in university level and thus impoverish the potential of them due to its excessive practice. This study then comes to explore the significant improvement over the use of pictorial analogy to promote university students’ skills in science oral communication towards the nervous system topic. Case study has been a design for the study. It involved two group of different students who participate in natural setting of human anatomy and physiology course. The data was gathered by observation and analyzed in descriptive manner. Quantitative and qualitative data are mixed up altogether to describe the reality behind learning process. The result showed that although both high and low achieving students are successful to communicate science concepts through pictorial analogy they are different in the way they accomodate what they want to explain. High achieving students outperform low achieving students in all aspects of oral presentation. They also employ more complex sources to draw the target concepts. To sum up, pictorial analogy can be used as a tool for students to do science communication skill in the form of oral presentation.

[Written and pictorial content in magazines and their possible relationship to eating disorders].

2012-02-01

In the current study we reviewed the literature on studies exploring the magazine reading frequency, written and pictorial contents appearing in magazines and their connection to eating disorders. Reading different fashion and fitness magazines has effect on readers through several indirect and direct factors and through trustable and false information. They affect readers' body satisfaction, self-esteem, eating habits and more generally their health behavior. Different theories have been explained to account for these associations and several other studies examined empirically the connection between the frequency of magazine reading and eating disorders, as well as the symptoms leading to eating disorders. We analyzed and summarized articles between 1975 and 2009 from online databases. We used the following sources: Science Direct (http://www.sciencedirect.com/), Springer-Verlag GmbH (http://www.springerlink.com/) and SAGE Publications Ltd (http://online.sagepub. com/). The pictorial and written magazine contents were associated with the development and maintenance of eating disorders or with symptoms that might lead to eating disorders. The publications compared to previous years featured an increased number of advertisements for unhealthy foods, for unhealthy radical diet plans and exercise programs. Furthermore the magazines contained conflicting messages about nutrition, body functions and eating disorders. Written and pictorial magazine contents, messages might increase the risk for development of eating disorders, especially in vulnerable individuals.

Objective This study aimed to determine the most effective content of pictorial health warning labels (HWLs) and whether educational attainment moderates these effects. Methods Field experiments were conducted with 529 adult smokers and 530 young adults (258 nonsmokers; 271 smokers), wherein participants reported responses to different HWLs printed on cigarette packages. One experiment involved manipulating textual form (testimonial narrative vs didactic) and the other involved manipulating imagery type (diseased organs vs human suffering). Results Tests of mean ratings and rankings indicated that HWLs with didactic textual forms had equivalent or significantly higher credibility, relevance, and impact than HWLs with testimonial forms. Results from mixed-effects models confirmed these results. However, responses differed by participant educational attainment: didactic forms were consistently rated higher than testimonials among participants with higher education, whereas the difference between didactic and testimonial narrative forms was weaker or not statistically significant among participants with lower education. In the second experiment, with textual content held constant, greater credibility, relevance and impact was found for graphic imagery of diseased organs than imagery of human suffering. Conclusions Pictorial HWLs with didactic textual forms appear to work better than with testimonial narratives. Future research should determine which pictorial HWL content has the greatest real-world impact among consumers from disadvantaged groups, including assessment of how HWL content should change to maintain its impact as tobacco control environments strengthen and consumer awareness of smoking-related risks increases.

This study examined the relationship between emotional understanding, friendship representation and reciprocity in school-aged children. Two hundred and fifty-one Caucasian 6-year-old children (111 males and 140 females) took part in the study. The Test of Emotion Comprehension (TEC) and the Pictorial Assessment of Interpersonal Relationships (PAIR) were used. Children having a reciprocal friendship and children having a unilateral friendship with a child named as their "best friend" were compared on the emotional understanding task and on their pictorial representations of friendship. Multilevel analyses indicated that friendship status effects were not influenced by classroom-level differences. Results showed that children with reciprocal friendships drew themselves as more similar to and more cohesive with their best friends, and they showed better understanding of emotions, than children having a unilateral friendship. Finally, the implications of these findings for theoretical and empirical research development on friendship are discussed.

In Lao PDR, health warnings were first introduced with printed warning messages on the side of the cigarette package in 1993 and again in 2004. Lao PDR same year ratified the Framework Convention on Tobacco Control (WHO FCTC) but has not yet implemented pictorial health warnings. This paper aims to examine the perception and opinion of policymakers on "text-only" and "pictorial" health warnings and to understand lay people's perceptions on current health warnings and their opinions on the recommended types of health warnings. A combination of quantitative and qualitative methods were used in this cross-sectional study conducted in 2008. A purposive sample of 15 policymakers, and a representative sample of 1360 smokers and non-smokers were recruited. A range of different areas were covered including consumer attitudes towards current and proposed cigarette package design, views on health warning messages on the flip/slide and inserts, and views on the relative importance of the size, content and pictures of health warning messages. Descriptive statistics and content analysis were used. Policy makers and survey respondents said that the current health warning messages were inappropriate, ineffective, and too small in size. All respondents perceived pictorial health warnings as a potentially powerful element that could be added to the messages that can communicate quickly, and dramatically. The majority of policymakers and survey respondents strongly supported the implementation of pictorial health warnings. The non-smokers agreed that the graphic pictorial health warnings were generally more likely than written health warnings to stimulate thinking about the health risks of smoking, by conveying potential health effects, increasing and reinforcing awareness of the negative health effect of smoking, aiding memorability of the health effects and arousing fear of smoking among smokers. The study suggested that current warnings are too small and that content is

In this article, we examined memory for pictures and words in middle-age (45-59 years), young-old (60-74 years), old-old (75-89 years) and the oldest-old adults (90-97 years) in the Louisiana Healthy Aging Study. Stimulus items were presented and retention was tested in a blocked order where half of the participants studied 16 simple line drawings and the other half studied matching words during acquisition. Free recall and recognition followed. In the next acquisition/test block, a new set of items was used where the stimulus format was changed relative to the first block. Results yielded pictorial superiority effects in both retention measures for all age groups. Follow-up analyses of clustering in free recall revealed a greater number of categories were accessed (which reflects participants' retrieval plan) and more items were recalled per category (which reflects participants' encoding strategy) when pictures served as stimuli compared to words. Cognitive status and working memory span were correlated with picture and word recall. Regression analyses confirmed that these individual difference variables accounted for significant age-related variance in recall. These data strongly suggest that the oldest-old can utilize nonverbal memory codes to support long-term retention as effectively as do younger adults. PMID:18651263

The conservation of artworks requires a profound knowledge about pictorial materials, their chemical and physical properties and their interaction and/or degradation processes. For this reason, pictorial materials databases are widely used to study and investigate cultural heritage. At Centre for Conservation and Restoration La Venaria Reale, we prepared a set of about 1200 mock-ups with 173 different pigments and/or dyes, used across all the historical times or as products for conservation, four binders, two varnishes and four different materials for underdrawings. In collaboration with the Laboratorio Analisi Scientifiche of Regione Autonoma Valle d'Aosta, the National Institute of Metrological Research and the Department of Architecture and Design of the Polytechnic of Turin, we created a scientific database that is now available online (http://www.centrorestaurovenaria.it/en/areas/diagnostic/pictorial-materials-database) designed as a tool for heritage science and conservation. Here, we present a focus on materials for pictorial retouching where the hyperspectral imaging application, conducted with a prototype of new technology, allowed to provide a list of pigments that could be more suitable for conservation treatments and pictorial retouching. Then we present the case study of the industrial painting Notte Barbara (1962) by Pinot Gallizio where the use of the database including modern and contemporary art materials showed to be very useful and where the fibre optics reflectance spectroscopy technique was decisive for pigment identification purpose. Later in this research, the mock-ups will be exploited to study degradation processes, e.g., the lightfastness, or the possible formation of interaction products, e.g., metal carboxylates.

Cigarette smoking is considered the first preventable cause of death in the world. Social, familial, and personal factors play an important role in prevention or cessation of smoking. Educating the public in order to enhance their knowledge, change their attitude and improve their habits is also effective in this respect. In 2007, the executive protocol of the Comprehensive Law on Smoking Control was compiled in the Ministry of Health and according to the Article 5 of this law pictorial health warning labels had to be applied on cigarette packaging. This study was designed and conducted in 2 phases of before and 9 months after the implementation of this law and evaluated the effect of it on smokers' knowledge, attitude and pattern of smoking. This was a cross-sectional descriptive study conducted to evaluate the effect of cigarette packs' pictorial health warning labels on the knowledge, attitude and smoking pattern of smokers residing in Tehran. After calculating the size of understudy population and estimation of the exclusions, 1731 subjects were randomly selected using the multiphase cluster method from the 22 districts of Tehran. Data were collected using a questionnaire designed according to the standard questionnaire of the World Health Organization (WHO) and International Union Against Tuberculosis and Lung Disease (IUATLD). Qualitative and quantitative value and reliability of the variables including cigarette consumption, knowledge about the law, and pattern of smoking were evaluated in 2 phases and the quality of pictures and their effects on the mentioned variables were assessed in the 2(nd) phase. Before adopting the pictorial warning labels in the first phase of the study, 1731 respondents were evaluated out of which 71.8% were males and 28.2% were females. These cases had an average of 17.6±12.3 years history of smoking. A total of 38% (675 subjects) used Iranian cigarette brands and 39.5% were aware of the implementation of pictorial health warning

Reduced effects of pictorial distinctiveness on false memory following dynamic visual noise.

Parker, Andrew; Kember, Timothy; Dagnall, Neil

2017-07-01

High levels of false recognition for non-presented items typically occur following exposure to lists of associated words. These false recognition effects can be reduced by making the studied items more distinctive by the presentation of pictures during encoding. One explanation of this is that during recognition, participants expect or attempt to retrieve distinctive pictorial information in order to evaluate the study status of the test item. If this involves the retrieval and use of visual imagery, then interfering with imagery processing should reduce the effectiveness of pictorial information in false memory reduction. In the current experiment, visual-imagery processing was disrupted at retrieval by the use of dynamic visual noise (DVN). It was found that effects of DVN dissociated true from false memory. Memory for studied words was not influenced by the presence of an interfering noise field. However, false memory was increased and the effects of picture-induced distinctiveness was eliminated. DVN also increased false recollection and remember responses to unstudied items.

Stormark, Kjell Morten; Torkildsen, Øivind

2004-01-01

This study investigated subjects with eating disorders' selective attention to linguistic and pictorial representations of food stimuli in a version of the Stroop color-naming task. If subjects with eating disorders' attention really are biased by food stimuli, one would expect equally delayed color-naming latencies to food pictures as previous studies have found to food words. Twenty females with eating disorders (anorexia nervosa, bulimia nervosa, or a combination of both) and 24 female controls identified the color of Stroop versions of linguistic and pictorial representations of color, food, emotional, and neutral stimuli. The eating disorder group was slower than the controls in identifying the color of all words (including the food words) and the pictures depicting food stimuli (but not any of the other pictures). The eating disorder group was also slower in identifying the color of both food and emotional than neutral stimuli, both for the linguistic and pictorial stimuli. These findings indicate that females with bulimia and anorexia nervosa's biased attention to food stimuli are not restricted to linguistic representations. The delayed responses to the emotional words and pictures suggest that processing of negative emotional stimuli, in addition to dysfunctional concerns about stimuli related to food and eating, is important in the maintenance of eating disorders.

The Effect of a Written and Pictorial Home Exercise Prescription on Adherence for People with Stroke

Directory of Open Access Journals (Sweden)

Sheetal Kara

2015-12-01

Conclusion: The addition of a written and pictorial home exercise prescription does not lead to better adherence to a home exercise programme compared to having no written and pictorial instructions. Possible reasons may be that patients had caregivers as a support system, and the exercise logbook served as a reminder and motivational track record for patients. There also does not appear to be a relationship between functional ability and level of adherence, which may be due to most of the study participants being within the optimal time frame for spontaneous functional recovery. Further study at different time frames in stroke rehabilitation in different contexts is recommended.

The result is “augmented reality” (AR. AR seamlessly superimposes virtual objects on to a real environment in three dimensions (3D and in real time. One of the most important parts that helps close the gap between virtuality and reality is the marker used in the AR system. While pictorial marker and bar-code marker are the two most commonly used marker types in the market, they have some disadvantages in visual and processing performance. In this paper, we present a novelty method that combines the bar-code with the original feature of a colour picture (e.g., photos, trading cards, advertisement’s figure. Our method decorates on top of the original pictorial images additional features with a single stereogram image that optically conceals a multi-level (3D bar-code. Thus, it has a larger capability of storing data compared to the general 1D barcode. This new type of marker has the potential of addressing the issues that the current types of marker are facing. It not only keeps the original information of the picture but also contains encoded numeric information. In our limited evaluation, this pictorial bar-code shows a relatively robust performance under various conditions and scaling; thus, it provides a promising AR approach to be used in many applications such as trading card games, educations, and advertisements.

Pictorial binding: endeavor to classify

Full Text Available The article is devoted to the classification of bindings of the 1-19th centuries with a unique and untypical book binding decoration technique (encaustic, tempera and oil paintings. Analysis of design features, materials and techniques of art decoration made it possible to identify them as a separate type - pictorial bindings and divide them into four groups. The first group consists of Coptic bindings, decorated with icon-painting images in encaustic technique. The second group is made up of leather Western bindings of the 13-14th centuries, which have the decoration and technique of ornamentation close to iconography. The third group involves parchment bindings, ornamentation technique of which is closer to the miniature. The last group comprises bindings of East Slavic origin of the 15-19th centuries, decorated with icon-painting pictures made in the technique of tempera or oil painting. The proposed classification requires further basic research as several specific kinds of bindings have not yet been investigated

Effects of redundancy in the comparison of speech and pictorial displays in the cockpit environment.

Science.gov (United States)

Byblow, W D

1990-06-01

Synthesised speech and pictorial displays were compared in a spatially compatible simulated cockpit environment. Messages of high or low levels of redundancy were presented to subjects in both modality conditions. Subjects responded to warnings presented in a warning-only condition and in a dual-task condition, in which a simulated flight task was performed with visual and manual input/output modalities. Because the amount of information presented in most real-world applications and experimental paradigms is quantifiably large with respect to present guidelines for the use of synthesised speech warnings, the low-redundancy condition was hypothesised to allow for better performance. Results showed that subjects respond quicker to messages of low redundancy in both modalities. It is suggested that speech messages with low-redundancy levels were effective in minimising message length and ensuring that messages did not overload the short-term memory required to process and maintain speech in memory. Manipulation of phrase structure was used to optimise message redundancy and enhance the conceptual compatibility of the message without increasing message length or imposing a perceptual cost or memory overload. The results also suggest that system response times were quicker when synthesised speech warnings were used. This result is consistent with predictions from multiple resource theory which states that the resources required for the perception of verbal warnings are different from those for the flight task. It is also suggested that the perception of a pictorial display requires the same resources used for the perception of the primary flight task. An alternative explanation is that pictorial displays impose a visual scanning cost which is responsible for decreased performance. Based on the findings reported here, it is suggested that speech displays be incorporated in a spatially compatible cockpit environment because they allow equal or better performance when

Zero Degree of Representation: Art, Technique and Pictorial Appearing

Directory of Open Access Journals (Sweden)

Full Text Available My starting hypothesis in the theory of pictorial appearing is that Gottfried Boehm’s notion of iconic difference can serve as a sufficiently comprehensive concept for differentiating between image and non-image in all visual artefacts that have been created during the several millennia of visual representation. This era started with the first paleolithic drawings and includes the entire visual production from the period “before art”, as well as all those visual representations that emerged in the early modern period beyond the needs of religious worship, only to be substituted through the technosphere. However, since the technosphere is characterized by increasingly evolved systems of visual immersion, from the all-accessible OLED screen and IMAX cinema theatres to Oculus Rift glasses and further to the experience of total immersion, which recreates synesthetic visual-haptic impressions, ontological differentiation between the visual surface as such and the extra-iconic reality can no longer be established with the idea of difference alone. Namely, the notion of difference can serve as a qualifier for defining the relationship between the separate categories in an object – in our case, the pictorial and non-pictorial ones – only insofar as the reality in which they are situated is identical or equivalent. Thus, nobody questions the clear ontological separation between the two-dimensional represented reality such as established in cinematic fiction and the non-represented, that is actual reality existing outside of that fiction. Many films and artworks count on that implied separation and can therefore afford to question the borderline between the two, primarily within a strictly artistic discourse. Boehm’s theory of iconic difference and Jean-Luc Nancy’s understanding of the cut have helped establish the semiotic-phenomenological criteria for a theoretical differentiation between various experiences that are innate to man�

Measuring Pictorial Balance Perception at First Glance using Japanese Calligraphy

Directory of Open Access Journals (Sweden)

Sharon Gershoni

2011-08-01

Full Text Available According to art theory, pictorial balance acts to unify picture elements into a cohesive composition. For asymmetrical compositions, balancing elements is thought to be similar to balancing mechanical weights in a framework of symmetry axes. Assessment of preference for balance (APB, based on the symmetry-axes framework suggested in Arnheim R, 1974 Art and Visual Perception: A Psychology of the Creative Eye (Berkeley, CA: University of California Press, successfully matched subject balance ratings of images of geometrical shapes over unlimited viewing time. We now examine pictorial balance perception of Japanese calligraphy during first fixation, isolated from later cognitive processes, comparing APB measures with results from balance-rating and comparison tasks. Results show high between-task correlation, but low correlation with APB. We repeated the rating task, expanding the image set to include five rotations of each image, comparing balance perception of artist and novice participant groups. Rotation has no effect on APB balance computation but dramatically affects balance rating, especially for art experts. We analyze the variety of rotation effects and suggest that, rather than depending on element size and position relative to symmetry axes, first fixation balance processing derives from global processes such as grouping of lines and shapes, object recognition, preference for horizontal and vertical elements, closure, and completion, enhanced by vertical symmetry.

In 2009, China changed its health warnings on cigarette packs from side-only text warnings to two text-only warnings on 30% of the bottom of the front and back of the pack. Also in 2009, Malaysia changed from similar text warnings to pictorial health warnings consistent with Framework Convention on Tobacco Control (FCTC) Article 11 Guidelines. To measure the impact of the change in health warnings in China and to compare the text-only health warnings to the impact of the pictorial health warnings introduced in Malaysia. We measured changes in key indicators of warning effectiveness among a longitudinal cohort sample of smokers from Waves 1 to 3 (2006-2009) of the International Tobacco Control (ITC) China Survey and from Waves 3 to 4 (2008-2009) of the ITC Malaysia Survey. Each cohort consisted of representative samples of adult (≥18 years) smokers from six cities in China (n=6575) and from a national sample in Malaysia (n=2883). Generalised Estimating Equations (GEE) were used to examine the impact of the health warnings on subsequent changes in salience of warnings, cognitive and behavioural outcomes. Compared to Malaysia, the weak text-only warning labels in China led to a significant change in only two of six key indicators of health warning effectiveness: forgoing cigarettes and reading the warning labels. The change to pictorial health warnings in Malaysia led to significant and substantial increases in five of six indicators (noticing, reading, forgoing, avoiding, thinking about quitting). The delay in implementing pictorial health warnings in China constitutes a lost opportunity for increasing knowledge and awareness of the harms of cigarettes, and for motivating smokers to quit.

Duncan, Christina L; Walker, Heather A; Brabson, Laurel; Williford, Desireé N; Hynes, Lisa; Hogan, Mary Beth

2017-09-21

Asthma action plans (AAPs) provide asthma management instructions to families; however, AAPs typically are written at a 7th-9th grade reading level, making them less useful in lower literacy families. There is a need to develop simpler AAP formats and content to optimize their utility across all families, including those who are rural and may be at a risk for literacy concerns. Because using pictures can simplify and enhance health education, our study's aim was to develop a pictorial AAP through a series of focus groups with key stakeholders - youth with asthma, caregivers, and physicians. Fourteen caregiver/youth dyads and four physicians participated in separate focus groups where their preferences for pictorial AAP structure and content were obtained. Focus groups were audio recorded, transcribed, coded with ATLAS.ti, and analyzed for themes. Youth and their caregivers prefer that the AAPs include simple, cartoon-like pictures customized to the patient. Physicians emphasized AAP's capability to display pictures of controller medication given its importance in preventing asthma exacerbations. A stoplight format, currently used in most written AAPs, received positive reviews. Specific suggestions for pictures showing symptoms, medications, and how to take medication were suggested. Words and short phrases accompanying the pictures were thought to add clarity. Key stakeholders viewed pictorial AAPs as positive and potentially effective alternatives to standard written AAPs. It is expected that low literacy youth and caregivers would more easily understand a pictorial AAP presentation, which should facilitate better medication adherence and asthma outcomes in these children.

Radiology of the nasopharynx: pictorial essay

International Nuclear Information System (INIS)

Chong, V.F.H.; Fan, Y.-F.

2000-01-01

The nasopharynx, located just below the central skull base, is a difficult area to evaluate clinically. Endoscopic examination provides useful information but cannot delineate submucosal disease. Benign lesions of the nasopharynx are relatively uncommon. They include Thornwaldt cyst, juvenile angiofibroma, haemangioma, haemangiopericytoma, Kimura's disease, branchial cleft cyst, oncocytoma, amyloidoma, and non-ossifying fibromyxoid tumours. The most common malignant lesions are carcinomas and lymphomas. Other malignant neoplasms such as adenocystic carcinomas are rarely seen. The purpose of the present pictorial review is to highlight the salient normal anatomy of the nasopharynx and the spectrum of pathological anatomy. Small or superficial lesions are best assessed endoscopically, coupled with biopsy when deemed necessary. It is demonstrated that both computerized tomography and MRI play a central role in the evaluation of lesions involving deeper structures of the nasopharynx, especially when skull base involvement or intracranial extension is suspected.

Current health care delivery models have increased the need for safe and concise patient handover. Handover interventions in the literature have focused on the use of structured tools but have not evaluated their ability to facilitate retention of patient information. In this study, mock pictorial displays were generated in an attempt to create a snapshot of each patient's medical and social circumstances. These pictorial displays contained the patient's photograph and other disease- and treatment-related images. The objective of this randomized trial was to assess the ability of these snapshots to enhance delayed information recall by care providers. Participating physicians were given four advanced cancer patient histories to review, two at a time over two weeks. Pictorial image displays, referred to as the Electronic Whiteboard (EWB) were added, in a randomized manner to half of the textual histories. The impact of the EWB on information recall was tested in immediate and delayed time frames. Overall, patient information recall declined significantly over time, with or without the EWB. Still, this trial demonstrates significantly higher test scores after 24 hours with the addition of pictures to textual patient information, compared with textual information alone (P = 0.0002). A more modest improvement was seen with the addition of the EWB for questionnaires administered immediately after history review (P = 0.008). Most participants agreed that the EWB was a useful enhancement and that seeing a patient's photograph improved their ability to retain information. Most studies examining the institution of handover protocols in the health care setting have failed to harness the power of pictures and other representative images. This study demonstrates the ability of pictorial displays to improve both immediate and delayed recall of patient histories without increasing review time. These types of displays may be amenable to generation by software programs and

Aural, visual, and pictorial stimulus formats in false recall.

Science.gov (United States)

Beauchamp, Heather M

2002-12-01

The present investigation is an initial simultaneous examination of the influence of three stimulus formats on false memories. Several pilot tests were conducted to develop new category associate stimulus lists. 73 women and 26 men (M age=21.1 yr.) were in one of three conditions: they either heard words, were shown words, or were shown pictures highly related to critical nonpresented items. As expected, recall of critical nonpresented stimuli was significantly greater for aural lists than for visually presented words and pictorial images. These findings demonstrate that the accuracy of memory is influenced by the format of the information encoded.

HIGHLIGHTS OF THE REPRESENTATION COSTUME IN PICTORIAL ART- BAROQUE STYLE -

URDEA Olimpia

2014-05-01

Full Text Available Throughout the social history of human civilization and art history, the human body was and still is a challenging field to explore in various representations, a material for various manners of cultural interventions. The way of artistically representing the body, the clothed body, has followed the path of various artistic movements that marked art history. In the act of interpersonal perception, the costume establishes itself as a particular field of non-verbal communication, one based on image. The present paper refers to the costume, as a particular vector of non-verbal communication in social space, as it was depicted and perceived in the painting of the 17th century and early 18th century, a time marked by the Baroque style. From this point of view, garment received the value of an intermediary in the communication between bodily space and the social one. In Baroque formal portrait, the garment completes by scale and the rendering technique of the texture and chromatic emphasizes the position of the pictorially represented person. Thus, the garment interferes with the gesture and mimics as forms of interpersonal knowledge. The transmitter – the clothed character represented through the eyes of the painter – is exposed to the perceptions of the others, providing a comprehensive matrix of information integrated in the social context. Pictorial representations are included in the matrix of the means by which the body is exposed by the costume in order to communicate with the social environment

Specific health warning placed on the tobacco product packages is considered as an effective and low-cost method for increasing the knowledge and awareness among the community. Thus, a study was conducted to assess the perception of pictorial health warnings (PHWs) against smoking among the adult rural population of Sarawak. Cross-sectional data were collected from 10 villages in Kota Samarahan and Kuching Division by face to face interview using modified Global Adult Tobacco Survey questionnaire. Nonprobability sampling method was adopted to select the villages. All the households of the selected villages were visited and an adult member was selected randomly from each house irrespective of the sex. After missing value imputation, 1000 data were analysed using statistical software IBM SPSS 20.0 version. Analysis showed that 28.8% of the respondents were current smokers, 7.8% were past smokers and the rest were non-smokers. Six items of pictorial health warnings were evaluated with five point Likert's scales for attractiveness, fearfulness and adequacy of the information. Analysis revealed that the majority of the respondents had perceived awareness on PHWs, but the smokers believed that this was not adequate to make them quit smoking. Only one-fifth (19.7%) of them reported that current pictorial health warnings were sufficient to motivate people to quit smoking. Though the PHWs on cigarette packages are appealing, it is not sufficient as a reason to stop smoking. Thus, an approach using an integrated anti-tobacco public health programme should be focused into the specific targeted community.

Pictorial Memory – Manners of the Individual Identity Construction

Directory of Open Access Journals (Sweden)

Milena Gnjatović

2015-08-01

Full Text Available The title of this study directly refers to the importance of the images, meaning material objects, personal memories or literal images – photographs one elects from the past in order to build up the individual identity and present it to others. Long ago, during the antique age, techniques of the remembrance by using pictorial memory and sequencing images from the past had been created, and those just developed during centuries. The goal of this paper is to stress that, basic concepts of the self representation did not change, but just used different media through time. In the first part of the paper, the difference between terms memory and remembrance, their relation to the culture and reasons why one remembers something will be discussed. As it is tended to be shown, the remembrance is always “pictorial”, one always puts elected images of the past in the exact order and creates its own identity. Therefore, in the second part of this study, the idea of individual identity, creation of it and the representation of the self identity to the others will be examined and explained in the context of the pictorial memory and heritage on the one hand, and social determination on the other. Inspired by the wholes one leaves in its personal life story when presenting it to others, the need of forgetting as constituent part of memory will also be stressed. Finally, the last part of this study points out that we still use the same concepts of remembering, electing and presenting images from the past in the creation of the image of ourselves, using the most popular media today - virtual space.

Hutchings, Jade N; Gannon, Theresa A; Gilchrist, Elizabeth

2010-04-01

A new pictorial assessment was developed to measure aggression-supportive cognitions among young aggressive male students. The assessment was comprised of 17 watercolor ambiguous sketches that could be interpreted in either an aggressive or a benign manner (e.g., two young people facing each other with their arms folded). The results showed that high trait aggressive male students were more likely to make hostile attributions of the pictures, providing significantly more themes of entitlement and power in the stories they generated about the pictures. Aggressive male students also endorsed significantly more aggression-supportive cognitions on a self-report measure and provided some supporting qualitative accounts of physically aggressive encounters. The results of this study are discussed and evaluated with reference to future work with young violent adolescents.

The purpose of this pictorial essay is to increase awareness of the clinical presentation, neuroradiological findings, treatment options, and neuroradiological follow-up of plasmacytomas and multiple myeloma with intracranial growth. This pictorial essay reviews the clinical features and neuroradiological findings in seven patients (four women, three men; age range at diagnosis 62-82 years) followed in two institutions. Six patients, one with IgG-{kappa} plasmacytoma, and five with IgG-{kappa}(n=3), IgG-{lambda}(n=1), and nonsecretory (n=1) multiple myeloma, had been seen over a period of 9 years in one institution, and the other patient with IgG-{kappa} plasmacytoma had been seen over a period of 3.5 years in the other. Intracranial involvement is rare, most frequently resulting from osseous lesions in the cranial vault, skull base, nose, or paranasal sinuses. Primary dural or leptomeningeal involvement is rarer. Some typical findings of a dural and/or osseous plasmacytoma include iso- to hyperdensity on CT scan, T1 equal to high signal intensity and T2 markedly hypointense signal on MRI, and high vascularity possibly documented on intraarterial digital subtraction angiography. However, the neuroradiological findings generally lack specificity, since they are generally no different from those of meningioma, metastasis, lymphoma, dural sarcoma, plasma cell granuloma, infectious meningitis, and leptomeningeal carcinomatosis. The spectrum of clinical and neuroradiological evaluation shows that intracranial involvement from plasmacytoma and multiple myeloma must be taken into account in the differential diagnosis of cranial osseous and meningeal disease.

The diagnosis of scrotal tumors in children can be challenging because of the rarity, vague symptoms, and varied imaging features of the tumors. The pathology and frequency of scrotal tumors that occur in children are different from tumors that arise in adults. In this pictorial essay, we illustrate the imaging findings of scrotal tumors in children with pathological correlations. In addition, we present the clinical manifestations that are valuable for a differential diagnosis. Familiarity with the imaging findings and clinical manifestations of pediatric scrotal tumors may be helpful in making an accurate diagnosis and providing proper patient management

Tarrant, A M

2012-02-03

Hypovolaemic shock is an infrequently encountered entity found on CT of victims of severe trauma. Early abdominal and pelvic CT can show diffuse abnormalities owing to hypovolaemia that may alert radiologists to the presence of hypovolaemic shock. In this pictorial review, we present the imaging findings of hypovolaemic shock, as seen on CT of the abdomen. A spectrum of vascular and visceral CT signs is described. Vascular signs include diminished inferior vena cava diameter, diminished aortic diameter and abnormal vascular enhancement. Hollow visceral abnormalities include diffuse increased mucosal enhancement of both the small and large bowel, diffuse thickening of the small bowel wall, and small bowel dilatation. Solid visceral abnormalities include both decreased and increased end organ enhancement. This report should increase radiologists\\' awareness of the CT manifestations of hypovolaemic shock.

In this study, we aimed to examine, in Thailand, the impact on smokers' reported awareness of and their cognitive and behavioral reactions following the change from text-only to pictorial warnings printed on cigarette packs. We also sought to explore differences by type of cigarette smoked (roll-your-own [RYO] vs. factory-made [FM] cigarettes). Data came from the International Tobacco Control Southeast Asia Survey, conducted in Thailand and Malaysia, where a representative sample of 2,000 adult smokers from each country were recruited and followed up. We analyzed data from one wave before (Wave 1) and two waves after the implementation of the new pictorial warnings (two sets introduced at Waves 2 and 3, respectively) in Thailand, with Malaysia, having text-only warnings, serving as a control. Following the warning label change in Thailand, smokers' reported awareness and their cognitive and behavioral reactions increased markedly, with the cognitive and behavioral effects sustained at the next follow-up. By contrast, no significant change was observed in Malaysia over the same period. Compared to smokers who smoke any FM cigarettes, smokers of only RYO cigarettes reported a lower salience but greater cognitive reactions to the new pictorial warnings. The new Thai pictorial health warning labels have led to a greater impact than the text-only warning labels, and refreshing the pictorial images may have helped sustain effects. This finding provides strong support for introducing pictorial warning labels in low- and middle-income countries, where the benefits may be even greater, given the lower literacy rates and generally lower levels of readily available health information on the risks of smoking.

We have detected [C i] {sup 3} P {sub 1}–{sup 3} P {sub 0} emissions in the gaseous debris disks of 49 Ceti and β Pictoris with the 10 m telescope of the Atacama Submillimeter Telescope Experiment, which is the first detection of such emissions. The line profiles of [C i] are found to resemble those of CO( J = 3–2) observed with the same telescope and the Atacama Large Millimeter/submillimeter Array. This result suggests that atomic carbon (C) coexists with CO in the debris disks and is likely formed by the photodissociation of CO. Assuming an optically thin [C i] emission with the excitation temperature ranging from 30 to 100 K, the column density of C is evaluated to be (2.2 ± 0.2) × 10{sup 17} and (2.5 ± 0.7) × 10{sup 16} cm{sup −2} for 49 Ceti and β Pictoris, respectively. The C/CO column density ratio is thus derived to be 54 ± 19 and 69 ± 42 for 49 Ceti and β Pictoris, respectively. These ratios are higher than those of molecular clouds and diffuse clouds by an order of magnitude. The unusually high ratios of C to CO are likely attributed to a lack of H{sub 2} molecules needed to reproduce CO molecules efficiently from C. This result implies a small number of H{sub 2} molecules in the gas disk, i.e., there is an appreciable contribution of secondary gas from dust grains.

From emblems to diagrams: Kepler's new pictorial language of scientific representation.

Science.gov (United States)

Chen-Morris, Raz

2009-01-01

Kepler's treatise on optics of 1604 furnished, along with technical solutions to problems in medieval perspective, a mathematically-based visual language for the observation of nature. This language, based on Kepler's theory of retinal pictures, ascribed a new role to geometrical diagrams. This paper examines Kepler's pictorial language against the backdrop of alchemical emblems that flourished in and around the court of Rudolf II in Prague. It highlights the cultural context in which Kepler's optics was immersed, and the way in which Kepler attempted to demarcate his new science from other modes of the investigation of nature.

Context. The search for extrasolar planets has been limited so far to close orbit (typ. ≤5 au) planets around mature solar-type stars on the one hand, and to planets on wide orbits (≥10 au) around young stars on the other hand. To get a better view of the full giant planet population, we have started a survey to search for giant planets around a sample of carefully selected young stars. Aims: This paper aims at exploring the giant planet population around one of our targets, β Pictoris, over a wide range of separations. With a disk and a planet already known, the β Pictoris system is indeed a very precious system for studies of planetary formation and evolution, as well as of planet-disk interactions. Methods: We analyse more than 2000 HARPS high-resolution spectra taken over 13 years as well as NaCo images recorded between 2003 and 2016. We combine these data to compute the detection probabilities of planets throughout the disk, from a fraction of au to a few dozen au. Results: We exclude the presence of planets more massive than 3 MJup closer than 1 au and further than 10 au, with a 90% probability. 15+ MJup companions are excluded throughout the disk except between 3 and 5 au with a 90% probability. In this region, we exclude companions with masses larger than 18 (resp. 30) MJup with probabilities of 60 (resp. 90) %. Based on data obtained with the ESO3.6 m/HARPS spectrograph at La Silla, and with NaCO on the VLT.The RV data are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/612/A108

Hardy, Lorna; Hogarth, Lee

2017-12-01

This study tested whether a novel concurrent pictorial choice procedure, inspired by animal self-administration models, is sensitive to the motivational effect of negative mood induction on alcohol-seeking in hazardous drinkers. Forty-eight hazardous drinkers (scoring ≥7 on the Alcohol Use Disorders Inventory) recruited from the community completed measures of alcohol dependence, depression, and drinking coping motives. Baseline alcohol-seeking was measured by percent choice to enlarge alcohol- versus food-related thumbnail images in two alternative forced-choice trials. Negative and positive mood was then induced in succession by means of self-referential affective statements and music, and percent alcohol choice was measured after each induction in the same way as baseline. Baseline alcohol choice correlated with alcohol dependence severity, r = .42, p = .003, drinking coping motives (in two questionnaires, r = .33, p = .02 and r = .46, p = .001), and depression symptoms, r = .31, p = .03. Alcohol choice was increased by negative mood over baseline (p choice was not related to gender, alcohol dependence, drinking to cope, or depression symptoms (ps ≥ .37). The concurrent pictorial choice measure is a sensitive index of the relative value of alcohol, and provides an accessible experimental model to study negative mood-induced relapse mechanisms in hazardous drinkers.

Pose estimation of people have had great progress in recent years but so far research has dealt with single persons. In this paper we address some of the challenges that arise when doing pose estimation of interacting people. We build on the pictorial structures framework and make important...... contributions by combining color-based appearance and edge information using a measure of the local quality of the appearance feature. In this way we not only combine the two types of features but dynamically find the optimal weighting of them. We further enable the method to handle occlusions by searching...... a foreground mask for possible occluded body parts and then applying extra strong kinematic constraints to find the true occluded body parts. The effect of applying our two contributions are show through both qualitative and quantitative tests and show a clear improvement on the ability to correctly localize...

Splenic Anomalies of Shape, Size, and Location: Pictorial Essay

Directory of Open Access Journals (Sweden)

Adalet Elcin Yildiz

2013-01-01

Full Text Available Spleen can have a wide range of anomalies including its shape, location, number, and size. Although most of these anomalies are congenital, there are also acquired types. Congenital anomalies affecting the shape of spleen are lobulations, notches, and clefts; the fusion and location anomalies of spleen are accessory spleen, splenopancreatic fusion, and wandering spleen; polysplenia can be associated with a syndrome. Splenosis and small spleen are acquired anomalies which are caused by trauma and sickle cell disease, respectively. These anomalies can be detected easily by using different imaging modalities including ultrasonography, computed tomography, magnetic resonance imaging, and also Tc-99m scintigraphy. In this pictorial essay, we review the imaging findings of these anomalies which can cause diagnostic pitfalls and be interpreted as pathologic processes.

Thyroid imaging is indicated to evaluate congenital hypothyroidism during newborn screening or in cases of a palpable thyroid mass in children and adolescents. This pictorial essay reviews the ultrasonography (US) of thyroid diseases in children and adolescents, including normal thyroid gland development, imaging features of congenital thyroid disorders (dysgenesis, [aplasia, ectopy, hypoplasia], dyshormonogenesis, transient hypothyroidism, thyroglossal duct cyst), diffuse thyroid disease (Grave's disease, Hashimoto's thyroiditis, and suppurative thyroiditis), and thyroid nodules. The primary imaging modalities for evaluating thyroid diseases are US and radionuclide scintigraphy. Additionally, US can be used to guide aspiration of detected nodules.

Intersection of reality and fiction in art perception: pictorial space, body sway and mental imagery.

Science.gov (United States)

Ganczarek, Joanna; Ruggieri, V; Nardi, D; Olivetti Belardinelli, M

2015-09-01

The thesis of embodied cognition claims that perception of the environment entails a complex set of multisensory processes which forms a basis for the agent's potential and immediate actions. However, in the case of artworks, an agent becomes an observer and action turns into a reaction. This raises questions about the presence of embodied or situated cognition involved in art reception. The study aimed to assess the bodily correlates of perceiving fictional pictorial spaces in the absence of a possibility of an actual physical immersion or manipulation of represented forms. The subjects were presented with paintings by Vermeer and De Hooch, whilst their body sway and eye movements were recorded. Moreover, test and questionnaires on mental imagery (MRT, VVIQ and OSIQ) were administered. Three major results were obtained: (1) the degree of pictorial depth did not influence body sway; (2) fixations to distant elements in paintings (i.e. backgrounds) were accompanied by an increase in body sway; and (3) mental rotation test scores correlated positively with body sway. Our results suggest that in certain cases--despite the fictional character of art--observers' reactions resemble reactions to real stimuli. It is proposed that these reactions are mediated by mental imagery (e.g. mental rotation) that contributes to the act of representing alternative to real artistic spaces.

How a mentalistic theory widens children’s conception of pictorial possibilities

Directory of Open Access Journals (Sweden)

Gabriella eGilli

2016-02-01

Full Text Available An interpretative theory of mind enables young children to grasp that people fulfil varying intentions when making pictures. It is not known when children widen their conception of artists’ intentions beyond that of picture-production, to include artists’ intention to show their pictures to others. We report studies centring on aspects of picture-exhibition, involving normal public display as well as the contrary intentions of hiding an original picture and of deceitfully displaying a forgery. Children aged between five and ten years viewed a brief video of an artist deliberately hiding her picture but her intention was thwarted when her picture was discovered and displayed. The first interview revealed that by eight years of age children were almost unanimous that a picture-producer without an intention to show her work to others cannot be considered to be an artist. Subsequent interviews revealed that the concept of exhibition widened to take others’ minds into account viewers’ critical judgements, and effects of forgeries on viewers’ minds. An increasingly mentalistic approach enables children to understand diverse possibilities in the art domain. The present technique of interpolating probes of typical possibilities between atypical intentions generated evidence that in middle childhood the foundations are laid for a conception of communication between artists’ minds and viewers’ minds via pictorial display.

This study was designed to assess the psychometric properties of a pictorial scale of correct condom use (PSCCU) using data from female sex workers (FSWs) in China. The psychometric properties assessed in this study include construct validity by correlations and known-group validation. The study sample included 396 FSWs in Guangxi, China. The results demonstrate adequate validity of the PSCCU among the study population. FSWs with a higher level of education scored significantly higher on the PSCCU than those with a lower level of education. FSWs who self-reported appropriate condom use with stable partners scored significantly higher on PSCCU than their counterparts. The PSCCU should provide HIV/STI prevention researchers and practitioners with a valid alternative assessment tool among high-risk populations, especially in resource-limited settings.

Neoplastic abdominal tumours, particularly those originating from embryonal tissue (such as hepatoblastoma and nephroblastoma) and neural crest cells (such as neuroblastoma), are well-documented in young children. Neoplasms of adulthood, most commonly carcinoma of different visceral organs, are also well-documented. Abdominal tumours in adolescence constitute a distinct pathological group. The radiological features of some of these tumours have been described only in isolated reports. The purpose of this pictorial essay was to review the imaging findings of various kinds of abdominal tumours in adolescent patients (with an age range of 10-16 years) who presented to the Children Cancer Center of our institution in the past 15 years. Some tumours, though rare, have characteristic imaging appearances (especially in CT) that enable an accurate diagnosis before definite histological confirmation. (orig.)

Pictorial essay of radiological features of benign intrathoracic masses

Directory of Open Access Journals (Sweden)

Syahminan Suut

2015-01-01

Full Text Available With increased exposure of patients to routine imaging, incidental benign intrathoracic masses are frequently recognized. Most have classical imaging features, which are pathognomonic for their benignity. The aim of this pictorial review is to educate the reader of radiological features of several types of intrathoracic masses. The masses are categorized based on their location/origin and are grouped into parenchymal, pleural, mediastinal, or bronchial. Thoracic wall masses that invade the thorax such as neurofibromas and lipomas are included as they may mimic intrathoracic masses. All examples are illustrated and include pulmonary hamartoma, pleural fibroma, sarcoidosis, bronchial carcinoid, and bronchoceles together with a variety of mediastinal cysts on plain radiographs, computed tomography (CT and magnetic resonance imaging (MRI. Sometimes a multimodality approach would be needed to confirm the diagnosis in atypical cases. The study would include the incorporation of radionuclide studies and relevant discussion in a multidisciplinary setting.

2017-01-15

Tuberous sclerosis complex (TSC) is a genetically determined hamartomatous neurocutaneous disease with high phenotypic variability. TSC is characterized by widespread hamartomas and benign, or rarely malignant, neoplasms distributed in several organs throughout the body, especially in the brain, skin, retina, kidney, heart, and lung. Common manifestations include cortical tubers, subependymal nodules, white matter abnormalities, retinal abnormalities, cardiac rhabdomyoma, lymphangioleiomyomatosis, renal angiomyolipoma, and skin lesions. The wide range of organs affected by the disease implies that TSC1 and TSC2 genes play important roles in the regulation of cell proliferation and differentiation. Although recent advances in treatment have improved morbidity, the prognosis remains quite poor and nearly 40% of patients die by the age of 35 years. Imaging is important in the evaluation of TSC because of its role not only in presumptive diagnosis, but also in defining the full extent of involvement. This information allows a better understanding of the behavioural phenotype, as related to lesion location. Imaging also contributes to treatment planning. This pictorial review describes common and uncommon imaging manifestations of TSC. (author)

Multidetector computed tomographic angiography is becoming the modality of choice for evaluation of the supra-aortic circulation in acute stroke imaging. Variations of the supra-aortic circulation, in particular of the extracranial arteries, are common. This article aims to provide a pictorial description of the variant anatomy of the aortic arch and extracranial arteries. Knowledge of the presence and clinical relevance of normal variants such as anomalies, duplications and embryological persistence plays a clinically relevant role in the diagnosis and management of neurological and surgical conditions, particularly as we enter an era of increasing extracranial intervention.

An essay on dreaming, psychical working out and working through.

Science.gov (United States)

da Rocha Barros, Elias M

2002-10-01

In this paper the author attempts to expand the idea put forward by Freud who considered dreams as a special form of unconscious thinking. It is the author's contention that the psychical working-out function performed by dreams is a form of unconscious thinking, which transforms affects into memories and mental structures. He also attempts to clarify the way in which meaning is built and transformed in mental life. In that respect the unconscious internal world is seen as a form of unconscious thinking, a private theatre where meaning is generated and transformed. He focuses on what happens to feelings in dreams in connection with the meanings as a result of and an expression of the several stages of working through. The dream world is described as the setting where the mind gives expressive pictorial representation to the emotions involved in a conflict: a first step towards thinkability. The dreamwork also constitutes a process through which meaning is apprehended, built on and transformed at an expressive non-discursive level, based on representation through figurative/pictorial images. The author draws on Meltzer's formulation to conjecture that the working-through function of dreams, mainly in response to interpretations, is performed by a process of progression in formal qualities of the representations made available by dreaming in the form he has called affective pictograms. It is through progression in formal qualities of the representation that the thinking capabilities of the affective life develop and become part of the process of what is called metaphorically the metabolisation of emotional life. This process takes place through migration of meaning across various levels of mental process. In this perspective the analyst's interpretations of dreams effect what linguists call transmutation of the symbolic basis, a process that is necessary to help the mind to improve its capacity to think.

To study whether data on maternal mortality can be gathered while maintaining local ownership of data in a pastoralist setting where a scarcity of data sources and a culture of silence around maternal death amplifies limited awareness of the magnitude of maternal mortality. As part of a participatory action research project, investigators and illiterate traditional birth attendants (TBAs) collaboratively developed a quantitative participatory tool-the Pictorial Sisterhood Method-that was pilot-tested between March 12 and May 30, 2011, by researchers and TBAs in a cross-sectional study. Fourteen TBAs interviewed 496 women (sample), which led to 2241 sister units of risk and a maternal mortality ratio of 689 deaths per 100000 live births (95% confidence interval 419-959). Researchers interviewed 474 women (sample), leading to 1487 sister units of risk and a maternal mortality ratio of 484 (95% confidence interval 172-795). The Pictorial Sisterhood Method is an innovative application that might increase the participation of illiterate individuals in maternal health research and advocacy. It offers interesting opportunities to increase maternal mortality data ownership and awareness, and warrants further study and validation.

DSA volumetric 3D reconstructions of intracranial aneurysms: A pictorial essay

Science.gov (United States)

Cieściński, Jakub; Serafin, Zbigniew; Strześniewski, Piotr; Lasek, Władysław; Beuth, Wojciech

2012-01-01

Summary A gold standard of cerebral vessel imaging remains the digital subtraction angiography (DSA) performed in three projections. However, in specific clinical cases, many additional projections are required, or a complete visualization of a lesion may even be impossible with 2D angiography. Three-dimensional (3D) reconstructions of rotational angiography were reported to improve the performance of DSA significantly. In this pictorial essay, specific applications of this technique are presented in the management of intracranial aneurysms, including: preoperative aneurysm evaluation, intraoperative imaging, and follow-up. Volumetric reconstructions of 3D DSA are a valuable tool for cerebral vessels imaging. They play a vital role in the assessment of intracranial aneurysms, especially in evaluation of the aneurysm neck and the aneurysm recanalization. PMID:22844309

North-American norms for name disagreement: pictorial stimuli naming discrepancies.

Directory of Open Access Journals (Sweden)

Mary O'Sullivan

Full Text Available Pictorial stimuli are commonly used by scientists to explore central processes; including memory, attention, and language. Pictures that have been collected and put into sets for these purposes often contain visual ambiguities that lead to name disagreement amongst subjects. In the present work, we propose new norms which reflect these sources of name disagreement, and we apply this method to two sets of pictures: the Snodgrass and Vanderwart (S&V set and the Bank of Standardized Stimuli (BOSS. Naming responses of the presented pictures were classified within response categories based on whether they were correct, incorrect, or equivocal. To characterize the naming strategy where an alternative name was being used, responses were further divided into different sub-categories that reflected various sources of name disagreement. Naming strategies were also compared across the two sets of stimuli. Results showed that the pictures of the S&V set and the BOSS were more likely to elicit alternative specific and equivocal names, respectively. It was also found that the use of incorrect names was not significantly different across stimulus sets but that errors were more likely caused by visual ambiguity in the S&V set and by a misuse of names in the BOSS. Norms for name disagreement presented in this paper are useful for subsequent research for their categorization and elucidation of name disagreement that occurs when choosing visual stimuli from one or both stimulus sets. The sources of disagreement should be examined carefully as they help to provide an explanation of errors and inconsistencies of many concepts during picture naming tasks.

Computed tomography colonography is a minimally invasive method for screening for polyps and colorectal cancer, with extremely unusual complications, increasingly used in the clinical practice. In the last decade, developments in bowel preparation, imaging, and in the training of investigators have determined a significant increase in the method sensitivity. Images interpretation is accomplished through a combined analysis of two-dimensional source images and several types of three-dimensional renderings, with sensitivity around 96% in the detection of lesions with dimensions equal or greater than 10 mm in size, when analyzed by experienced radiologists. The present pictorial essay includes examples of diseases and pseudolesions most frequently observed in this type of imaging study. The authors present examples of flat and polypoid lesions, benign and malignant lesions, diverticular disease of the colon, among other conditions, as well as pseudolesions, including those related to inappropriate bowel preparation and misinterpretation.

The survival rate of patients with congenital heart disease (CHD) has dramatically improved over the last 2 decades because of technological and surgical advances in diagnosis and treatment, respectively. The vast majority of CHD patients are, in fact, amenable to treatment by either device closure or surgery. Considering the wide spectrum of surgical procedures and complex native and derived anatomy, continuous and detailed follow-up is of paramount importance. Cardiac magnetic resonance and cardiac computed tomography angiography are the cornerstones of diagnosis and follow-up of CHD, allowing for comprehensive noninvasive assessment of the heart, coronary tree, and intrathoracic great vessels, along with both morphological and functional evaluation. The aim of this pictorial review is to provide an overview of the most common CHDs and their related surgical procedures as familiarity with the radiological findings of grown-up congenital heart disease patients is crucial for proper diagnostic and follow-up pathways.

Automatic generation of pictorial transcripts of video programs

Science.gov (United States)

Shahraray, Behzad; Gibbon, David C.

1995-03-01

An automatic authoring system for the generation of pictorial transcripts of video programs which are accompanied by closed caption information is presented. A number of key frames, each of which represents the visual information in a segment of the video (i.e., a scene), are selected automatically by performing a content-based sampling of the video program. The textual information is recovered from the closed caption signal and is initially segmented based on its implied temporal relationship with the video segments. The text segmentation boundaries are then adjusted, based on lexical analysis and/or caption control information, to account for synchronization errors due to possible delays in the detection of scene boundaries or the transmission of the caption information. The closed caption text is further refined through linguistic processing for conversion to lower- case with correct capitalization. The key frames and the related text generate a compact multimedia presentation of the contents of the video program which lends itself to efficient storage and transmission. This compact representation can be viewed on a computer screen, or used to generate the input to a commercial text processing package to generate a printed version of the program.

Presently there is no consensus on the specific behavioral treatment of choice for targeting language in young nonverbal children with autism. This randomized clinical trial compared the effectiveness of a verbally-based intervention, Pivotal Response Training (PRT) to a pictorially-based behavioral intervention, the Picture Exchange Communication System (PECS) on the acquisition of spoken language by young (2-4 years), nonverbal or minimally verbal (≤9 words) children with autism. Thirty-nine children were randomly assigned to either the PRT or PECS condition. Participants received on average 247 h of intervention across 23 weeks. Dependent measures included overall communication, expressive vocabulary, pictorial communication and parent satisfaction. Children in both intervention groups demonstrated increases in spoken language skills, with no significant difference between the two conditions. Seventy-eight percent of all children exited the program with more than 10 functional words. Parents were very satisfied with both programs but indicated PECS was more difficult to implement.

We present spectral and kinematic evidence that 2MASS J06085283-2753583 (M8.5γ) is a member of the β Pictoris Moving Group (BPMG, age ∼12 Myr), making it the latest-type known member of this young, nearby association. We confirm low-gravity spectral morphology at both medium and high resolutions in the near-infrared. We present new radial velocity and proper motion measurements, and use these to calculate galactic location and space motion consistent with other high-probability members of the BPMG. The predicted mass range consistent with the object's effective temperature, surface gravity, spectral type, and age is 15-35 M Jup , placing 2MASS 0608-27 well within the brown dwarf mass regime. 2MASS J06085283-2753583 is thus confidently added to the short list of very low mass, intermediate age benchmark objects that inform ongoing searches for the lowest-mass members of nearby young associations.

The MRI features of placental adhesion disorder—a pictorial review

Teixidor Vinas, Mireia; Whitby, Elspeth

2016-01-01

Placental adhesion disorder (PAD) comprises placenta accreta, increta and percreta lesions; these are classified according to the depth of uterine invasion. Although PAD is considered a rare condition, its incidence has increased 10-fold in the last 50 years. Ultrasound is the primary imaging modality for the assessment of the placenta and in the majority of cases, it is sufficient for diagnosis; however, when ultrasound findings are suspicious or inconclusive, MRI is recommended as an adjunct imaging technique. Numerous MRI features of PAD have been described, including dark intraplacental bands, disorganized intraplacental vascularity and abnormal uterine bulging. This pictorial review describes and illustrates these characteristics and discusses their implications in planning delivery. In addition, we present a series of “pitfall” cases to aid the interpreting radiologist and discuss management of PAD. PAD is a clinical and diagnostic challenge that is encountered with increasing frequency, requiring a cohesive multidisciplinary approach to its management. PMID:27355318

T1 mapping is now a clinically feasible method, providing pixel-wise quantification of the cardiac structure's T1 values. Beyond focal lesions, well depicted by late gadolinium enhancement sequences, it has become possible to discriminate diffuse myocardial alterations, previously not assessable by noninvasive means. The strength of this method includes the high reproducibility and immediate clinical applicability, even without the use of contrast media injection (native or pre-contrast T1). The two most important determinants of native T1 augmentation are (1) edema related to tissue water increase (recent infarction or inflammation) and (2) interstitial space increase related to fibrosis (infarction scar, cardiomyopathy) or to amyloidosis. Conversely, lipid (Anderson-Fabry) or iron overload diseases are responsible for T1 reduction. In this pictorial review, the main features provided by native T1 mapping are discussed and illustrated, with a special focus on the awaited clinical purpose of this unique, promising new method.

The syndrome of ectopic adrenocorticotrophin secretion (EAS) is rare and is due to excess adrenocorticotrophin (ACTH) production from a nonpituitary tumour. These tumours can be covert, where the tumours are not readily apparent, and very small making them challenging to image. It is clinically and biochemically difficult to distinguish between covert EAS and Cushing's disease. The first-line investigation in locating the source of ACTH production is computed tomography (CT). The aim of this pictorial review is to illustrate the likely covert sites and related imaging findings. We review the CT appearances of tumours resulting in covert EAS and the associated literature. The most common tumours were bronchial carcinoid tumours, which appear as small, well-defined, round or ovoid pulmonary lesions. Rarer causes included thymic carcinoids, gastrointestinal carcinoids and pancreatic neuroendocrine tumours. Awareness of the imaging characteristics will aid identification of the source of ACTH production and allow potentially curative surgical resection. (orig.)

The term ‘emphysema’ is generally used in a morphological sense, and therefore imaging modalities have an important role in diagnosing this disease. In particular, high resolution computed tomography (HRCT) is a reliable tool for demonstrating the pathology of emphysema, even in subtle changes within secondary pulmonary lobules. Generally, pulmonary emphysema is classified into three types related to the lobular anatomy: centrilobular emphysema, panlobular emphysema, and paraseptal emphysema. In this pictorial review, we discuss the radiological – pathological correlation in each type of pulmonary emphysema. HRCT of early centrilobular emphysema shows an evenly distributed centrilobular tiny areas of low attenuation with ill-defined borders. With enlargement of the dilated airspace, the surrounding lung parenchyma is compressed, which enables observation of a clear border between the emphysematous area and the normal lung. Because the disease progresses from the centrilobular portion, normal lung parenchyma in the perilobular portion tends to be preserved, even in a case of far-advanced pulmonary emphysema. In panlobular emphysema, HRCT shows either panlobular low attenuation or ill-defined diffuse low attenuation of the lung. Paraseptal emphysema is characterized by subpleural well-defined cystic spaces. Recent topics related to imaging of pulmonary emphysema will also be discussed, including morphometry of the airway in cases of chronic obstructive pulmonary disease, combined pulmonary fibrosis and pulmonary emphysema, and bronchogenic carcinoma associated with bullous lung disease.

Thirty patients with thoracic hydatidosis (Echinococcus granulosus) were studied. The hydatid cysts were located in the lung parenchyma (70%), mediastinum (6.7%), inside the heart (10%), the pleurae (10%) and the chest wall (3.3%). Complications of thoracic hydatid cysts, such as rupture, infection, pleural involvement, spread and calcifications are presented. Computed tomography (CT) without and/or with contrast enhancement was performed in all patients (30). Findings from conventional chest radiographs were compared with CT and confirmed by pathology (30). In 10 cases (33.3%), magnetic resonance imaging was also performed. The diagnostic spectrum of hydatid cysts, including variations and developmental stages, is presented in this pictorial essay. (orig.)

Full Text Available Schwannomas are benign soft-tissue tumors that arise from peripheral nerve sheaths throughout the body and are commonly encountered in patients with neurofibromatosis Type 2. The vast majority of schwannomas are benign, with rare cases of malignant transformation reported. In this pictorial review, we discuss the magnetic resonance imaging (MRI appearance of schwannomas by demonstrating a collection of tumors from different parts of the body that exhibit similar MRI characteristics. We review strategies to distinguish schwannomas from malignant soft-tissue tumors while exploring the anatomic and histologic origins of these tumors to discuss how this correlates with their imaging findings. Familiarity with the MRI appearance of schwannomas can help aid in the differential diagnosis of soft-tissue masses, especially in unexpected locations.

This pictorial essay reviews the computed tomography (CT) findings of afferent loop syndrome (ALS) in various pathological conditions to demonstrate the contribution of a common imaging modality-that is, abdominal CT, used nowadays for various abdominal complaints-to the diagnosis of ALS. ALS is caused by obstruction of the duodenum and jejunum proximal to a gastrojejunostomy anastomosis. It is a rare complication after Billroth II subtotal gastrectomy and even more rare after total or subtotal gastrectomy with Roux-en-Y reconstruction. Although currently advanced medical treatment and endoscopic interventions have dramatically decreased the necessity of surgery for peptic ulcer disease, ALS may appear years after previously common operations. Alternatively, the use of surgical resection for early gastric cancer nowadays leads to an increasing rate of malignancy-related ALS. Clinically, ALS may be difficult to diagnose as its presentation may be vague and nonspecific, but it has a characteristic appearance on CT. Clinicians and radiologists should therefore be familiar with this rare complication. Prompt recognition and correct diagnosis of this syndrome and its probable etiology are important as a guide for treatment. This review illustrates the CT features of ALS in various conditions.

Directory of Open Access Journals (Sweden)

Full Text Available During the 18th century, Shakespeare’s Macbeth was a source of inspiration for many painters who tried to underscore the pictorial quality of the play, especially that of Act 1, scene 3. The paper compares the interpretations offered by Henry Fuseli and Francesco Zuccarelli who were both foreign artists belonging to the Royal Academy of London. Their paintings after Act 1, scene 3, of Macbeth offer a visual representation articulated around contrast and convergence: if Fuseli remains faithful to the pivotal emotional intent, seen as the “ergon” here, Zuccarelli almost ignores it, finding a greater interest in the landscape of the scene that fills most of his pictorial space. However, the two works fuse together within the etymology of the term “ergon”, that equates with “work” or “action”. They illustrate the idea of active witchcraft through natural phenomena controlled by the three witches.

We examined the effect of a semantic orienting task during encoding on free recall and recognition of simple line drawings and matching words in middle-aged (44 to 59 years), older (60 to 89 years), and oldest-old (90 + years) adults. Participants studied line drawings and matching words presented in blocked order. Half of the participants were given a semantic orienting task and the other half received standard intentional learning instructions. Results confirmed that the pictorial superiority effect was greater in magnitude following semantic encoding compared to the control condition. Analyses of clustering in free recall revealed that oldest-old adults’ encoding and retrieval strategies were generally similar to the two younger groups. Self-reported strategy use was less frequent among the oldest-old adults. These data strongly suggest that semantic elaboration is an effective compensatory mechanism underlying preserved episodic memory performance that persists well into the ninth decade of life.

Maćkiewicz, Marta; Cieciuch, Jan

2016-01-01

In order to adjust personality measurements to children's developmental level, we constructed the Pictorial Personality Traits Questionnaire for Children (PPTQ-C). To validate the measure, we conducted a study with a total group of 1028 children aged between 7 and 13 years old. Structural validity was established through Exploratory Structural Equation Model (ESEM). Criterion validity was confirmed with a multitrait-multimethod analysis for which we introduced the children's self-assessment scores from the Big Five Questionnaire for Children. Despite some problems with reliability, one can conclude that the PPTQ-C can be a valid instrument for measuring personality traits, particularly in a group of young children (aged ~7-10 years).

Previous research has shown that reminders can be effective for extending and enhancing a variety of kinds of memory in infants. We investigated the effects of viewing pictorial representations of actions that were included in imitation events used to measure long-term memory in young infants. Infants who saw the pictures of actions displayed in the order in which they comprised events showed evidence of memory for the events. Infants who saw the actions presented randomly did not. These results suggest that pictures presented during the consolidation and storage phase of memory formation can be effective reminders of events for young infants.

Full Text Available BACKGROUND: Intravaginal practices (IVP are highly prevalent in sub-Saharan African and have been implicated as risk factors for HIV acquisition. However, types of IVP vary between populations, and detailed information on IVP among women at risk for HIV in different populations is needed. We investigated IVP among women who practice transactional sex in two populations: semi-urban, facility workers in Tanzania who engage in opportunistic sex work; and urban, self-identified sex workers and bar workers in Uganda. The aim of the study was to describe and compare IVP using a daily pictorial diary. METHODOLOGY/PRINCIPAL FINDINGS: Two hundred women were recruited from a HIV prevention intervention feasibility study in Kampala, Uganda and in North-West Tanzania. Women were given diaries to record IVP daily for six weeks. Baseline data showed that Ugandan participants had more lifetime partners and transactional sex than Tanzanian participants. Results from the diary showed that 96% of Tanzanian participants and 100% of Ugandan participants reported intravaginal cleansing during the six week study period. The most common types of cleansing were with water only or water and soap. In both countries, intravaginal insertion (e.g. with herbs was less common than cleansing, but insertion was practiced by more participants in Uganda (46% than in Tanzania (10%. In Uganda, participants also reported more frequent sex, and more insertion related to sex. In both populations, cleansing was more often reported on days with reported sex and during menstruation, and in Uganda, when participants experienced vaginal discomfort. Participants were more likely to cleanse after sex if they reported no condom use. CONCLUSIONS: While intravaginal cleansing was commonly practiced in both cohorts, there was higher frequency of cleansing and insertion in Uganda. Differences in IVP were likely to reflect differences in sexual behaviour between populations, and may warrant

Using the recently installed Gemini Planet Imager (GPI), we have obtained the first H-band spectrum of the planetary companion to the nearby young star β Pictoris. GPI is designed to image and provide low-resolution spectra of Jupiter-sized, self-luminous planetary companions around young nearby stars. These observations were taken covering the H band (1.65 μm). The spectrum has a resolving power of ∼45 and demonstrates the distinctive triangular shape of a cool substellar object with low surface gravity. Using atmospheric models, we find an effective temperature of 1600-1700 K and a surface gravity of log (g) = 3.5-4.5 (cgs units). These values agree well with ''hot-start'' predictions from planetary evolution models for a gas giant with mass between 10 and 12 M Jup and age between 10 and 20 Myr

Sobre el estado evolutivo de β Pictoris

Brunini, A.; Benvenuto, O. G.

Desde el descubrimiento de fuertes excesos infrarrojos en β Pictoris, esta estrella ha sido muy estudiada y es considerada candidata a poseer un sistema planetario propio. β Pic está rodeada de un disco asimétrico de polvo que se observa de canto y que esta vacío a distancias de la presencia de (al menos) un planeta gigante. Recientemente se han observado líneas de material circunestelar que se han interpretado como consecuencia de la caída de objetos cometarios sobre esta estrella. Recientemente se ha utilizado la existencia del disco de polvo para atribuir una edad corta (pre - secuencia principal) a βPic. Sin embargo, la evaporación de estos cometas provee suficiente polvo como para explicar la presencia del disco observado sin necesidad de edades cortas. En este trabajo mostramos que la comparación entre la tasa de impactos cometarios estimada en el Sistema Solar para diferentes etapas de su evolución y los datos observados en β Pic indica edades avanzadas para β Pic. Esta estimación debe tomarse con cautela ya que depende de la estructura de los sistemas planetarios. Además mostramos que, desde el punto de vista de la evolución estelar y con las incertezas presentes en la luminosidad y la temperatura efectiva, existe un continuo de edades posible para β Pic. Sin embargo, empleando los datos provenientes de los flujos cometarios encontramos que una edad prolongada es consistente con ambos tratamientos.

Thymic tumors represent a broad spectrum of neoplastic disorders and pose considerable diagnostic difficulties. A non-invasive imaging study to determine the nature of thymic lesions can have significant impact on management of such tumors. 18F-flurorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography (PET-CT) has shown promising results in characterization of thymic tumors. The objective of this article is to provide an illustrative tutorial highlighting the clinical utility of 18F-FDG PET-CT imaging in patients with thymic tumors. We have pictorially depicted the 18F-FDG PET-CT salient imaging characteristics of various thymic tumors, both epithelial and non-epithelial. Also discussed is the dynamic physiology of thymus gland which is to be kept in mind when evaluating thymic pathology on 18F-FDG PET-CT, as it can lead to interpretative pitfalls

Magnetic resonance imaging of the wrist in early rheumatoid arthritis: a pictorial essay

International Nuclear Information System (INIS)

Stewart, N.R.; Crabbe, J.P.; McQueen, F.M.

2001-01-01

This pictorial essay describes the changes seen in the wrist in early rheumatoid arthritis (RA) on MRI. Magnetic resonance imaging can demonstrate bone erosions, bone marrow signal changes, synovitis and tenosynovitis in early rheumatoid arthritis. Magnetic resonance imaging of the wrist can identify erosions in RA earlier than plain radiographs and can detect more erosions. Common sites include the capitate, lunate and scaphoid. Bone marrow signal changes occur frequently and are most common in the capitate, lunate and triquetrum. Synovial thickening and enhancement are clearly demonstrated with MRI and are most commonly seen in the radiocarpal joint (RCJ). Tenosynovitis can be seen in the wrist in more than half of patients presenting with RA. This most commonly involves the extensor carpi ulnaris tendon and is seen as sheath fluid, thickening and enhancement. Copyright (2001) Blackwell Science Pty Ltd

This pictorial review highlights cancers detected only at tomosynthesis screening and screens falsely recalled in the course of breast tomosynthesis screening, illustrating both true-positive (TP) and false-positive (FP) detection attributed to tomosynthesis. Images and descriptive data were used to characterise cases of screen-detection with tomosynthesis, sourced from prospective screening trials that performed standard (2D) digital mammography (DM) and tomosynthesis (3D-mammography) in the same screening participants. Exemplar cases from four trials highlight common themes of relevance to screening practice including: the type of lesions frequently made more conspicuous or perceptible by tomosynthesis (spiculated masses, and architectural distortions); the histologic findings (both TP and FP) of tomosynthesis-only detection; and the need to extend breast work-up protocols (additional imaging including ultrasound and MRI, and tomosynthesis-guided biopsy) if tomosynthesis is adopted for primary screening.

2015-08-01

The purpose was to determine the reliability of an instrument designed to assess young children's perceived movement skill competence in 2 diverse samples. A pictorial instrument assessed 12 perceived Fundamental Movement Skills (FMS) based on the Test of Gross Motor Development 2nd edition. Intra-Class Correlations (ICC) and internal consistency analyses were conducted. Paired sample t tests assessed change in mean perceived skill scores. Bivariate correlations between the intertrial difference and the mean of the trials explored proportional bias. Sample 1 (S1) were culturally diverse Australian children (n = 111; 52% boys) aged 5 to 8 years (mean = 6.4, SD = 1.0) with educated parents. Sample 2 (S2) were racially diverse and socioeconomically disadvantaged American children (n = 110; 57% boys) aged 5 to 10 years (mean = 6.8, SD = 1.1). For all children, the internal consistency for 12 FMS was acceptable (S1 = 0.72, 0.75, S2 = 0.66, 0.67). ICCs were higher in S1 (0.73) than S2 (0.50). Mean changes between trials were small. There was little evidence of proportional bias. Lower values in S2 may be due to differences in study demographic and execution. While the instrument demonstrated reliability/internal consistency, further work is recommended in diverse samples.

Leishmaniasis direct agglutination test: using pictorials as training materials to reduce inter-reader variability and improve accuracy.

Directory of Open Access Journals (Sweden)

Emily R Adams

Full Text Available BACKGROUND: The Direct Agglutination Test (DAT has a high diagnostic accuracy and remains, in some geographical areas, part of the diagnostic algorithm for Visceral Leishmaniasis (VL. However, subjective interpretation of results introduces potential for inter-reader variation. We report an assessment of inter-laboratory agreement and propose a pictorial-based approach to standardize reading of the DAT. METHODOLOGY: In preparation for a comparative evaluation of immunochromatographic diagnostics for VL, a proficiency panel of 15 well-characterized sera, DAT-antigen from a single batch and common protocol was sent to nine laboratories in Latin-America, East-Africa and Asia. Agreement (i.e., equal titre or within 1 titer with the reading by the reference laboratory was computed. Due to significant inter-laboratory disagreement on-site refresher training was provided to all technicians performing DAT. Photos of training plates were made, and end-titres agreed upon by experienced users of DAT within the Visceral-Leishmaniasis Laboratory-Network (VL-LN. RESULTS: Pre-training, concordance in DAT results with reference laboratories was only 50%, although agreement on negative sera was high (94%. After refresher training concordance increased to 84%; agreement on negative controls increased to 98%. Variance in readings significantly decreased after training from 3.3 titres to an average of 1.0 titre (two-sample Wilcoxon rank-sum (Mann-Whitney test (z = -3,624 and p = 0.0003. CONCLUSION: The most probable explanation for disagreement was subjective endpoint reading. Using pictorials as training materials may be a useful tool to reduce disparity in results and promote more standardized reading of DAT, without compromising diagnostic sensitivity.

Magnetic resonance imaging of the growth plate: pictorial essay

International Nuclear Information System (INIS)

Cairns, R.

2003-01-01

The approach to musculoskeletal magnetic resonance imaging (MRI) is very different in children than adults because of different disease processes, immature structures and the variable size and age of the patients. Use of routine adult musculoskeletal protocols and techniques may not provide sufficient information in children, and most pediatric examinations should be customized to specifically address the child's age and clinical problem. This pictorial essay will illustrate MRI of the growth plate - often an area of uncertainty or error for radiologists who infrequently perform musculoskeletal MRI on children. The growth plate or physis is a structure unique to the growing skeleton. It is a cartilaginous zone located between the epiphysis and the metaphysis that functions to provide longitudinal bone growth. Disturbance of physeal growth as a result of trauma, infection, tumour, ischemia or radiation can result in leg length discrepancy, angular deformity or altered joint mechanics and cause significant long-term disability. MRI can directly image cartilaginous structures and has thus become the imaging method of choice for evaluation of the growth plate. An understanding of the normal and abnormal appearance of growth cartilage and of MRI protocols optimized for imaging the growth plate, combined with an approach to risk assessment for the development of significant growth deformity, is needed to confidently image the growth plate and help direct the management of these patients.

Minakata, Hisakazu; Nunokawa, Hiroshi

2003-01-01

We introduce a 'CP trajectory diagram in bi-probability space' as a powerful tool for a pictorial representation of the genuine CP and the matter effects in neutrino oscillations. The existence of correlated ambiguity in the determination of CP-violating phase δ and the sign of Δm 13 2 is uncovered. The principles of tuning the beam energy for a given baseline distance are proposed to resolve the ambiguity and to maximize the CP-odd effect. We finally point out, quite contrary to what is usually believed, that the ambiguity may be resolved with ∼50% chance in the super-JHF experiment despite its relatively short baseline of 300 km

2017-03-01

Zika virus (ZIKV) is a mosquito-borne arbovirus from the Flaviviridae family. It had caused several epidemics since its discovery in 1947, but there was no significant attention to this virus until the recent outbreak in Brazil in 2015. The main concern is the causal relationship between prenatal ZIKV infection and congenital microcephaly, which has been confirmed recently. Moreover, ZIKV may cause other central nervous system abnormalities such as brain parenchymal atrophy with secondary ventriculomegaly, intracranial calcification, malformations of cortical development (such as polymicrogyria, and lissencephaly-pachygyria), agenesis/hypoplasia of the corpus callosum, cerebellar and brainstem hypoplasia, sensorineural hearing-loss, and ocular abnormalities as well as arthrogryposis in the infected fetuses. Postnatal (acquired) ZIKV infection usually has an asymptomatic or mildly symptomatic course, while prenatal (congenital) ZIKV infection has a more severe course and may cause severe brain anomalies that are described as congenital Zika syndrome. In this pictorial essay, we aim to illustrate the prenatal and postnatal neuroimaging findings that may be seen in fetuses and neonates with congenital Zika syndrome, and will discuss possible radiological differential diagnoses. A detailed knowledge of these findings is paramount for an early correct diagnosis, prognosis determination, and counseling of the affected children and families.

Food-related attentional bias. Word versus pictorial stimuli and the importance of stimuli calorific value in the dot probe task.

Science.gov (United States)

Freijy, Tanya; Mullan, Barbara; Sharpe, Louise

2014-12-01

The primary aim of this study was to extend previous research on food-related attentional biases by examining biases towards pictorial versus word stimuli, and foods of high versus low calorific value. It was expected that participants would demonstrate greater biases to pictures over words, and to high-calorie over low-calorie foods. A secondary aim was to examine associations between BMI, dietary restraint, external eating and attentional biases. It was expected that high scores on these individual difference variables would be associated with a bias towards high-calorie stimuli. Undergraduates (N = 99) completed a dot probe task including matched word and pictorial food stimuli in a controlled setting. Questionnaires assessing eating behaviour were administered, and height and weight were measured. Contrary to predictions, there were no main effects for stimuli type (pictures vs words) or calorific value (high vs low). There was, however, a significant interaction effect suggesting a bias towards high-calorie pictures, but away from high-calorie words; and a bias towards low-calorie words, but away from low-calorie pictures. No associations between attentional bias and any of the individual difference variables were found. The presence of a stimulus type by calorific value interaction demonstrates the importance of stimuli type in the dot probe task, and may help to explain inconsistencies in prior research. Further research is needed to clarify associations between attentional bias and BMI, restraint, and external eating. Copyright © 2014 Elsevier Ltd. All rights reserved.

2015-01-01

To determine reliability and face validity of an instrument to assess young children's perceived fundamental movement skill competence. Validation and reliability study. A pictorial instrument based on the Test Gross Motor Development-2 assessed perceived locomotor (six skills) and object control (six skills) competence using the format and item structure from the physical competence subscale of the Pictorial Scale of Perceived Competence and Acceptance for Young Children. Sample 1 completed object control items in May (n=32) and locomotor items in October 2012 (n=23) at two time points seven days apart. Children were asked at the end of the test-retest their understanding of what was happening in each picture to determine face validity. Sample 2 (n=58) completed 12 items in November 2012 on a single occasion to test internal reliability only. Sample 1 children were aged 5-7 years (M=6.0, SD=0.8) at object control assessment and 5-8 years at locomotor assessment (M=6.5, SD=0.9). Sample 2 children were aged 6-8 years (M=7.2, SD=0.73). Intra-class correlations assessed in Sample 1 children were excellent for object control (intra-class correlation=0.78), locomotor (intra-class correlation=0.82) and all 12 skills (intra-class correlations=0.83). Face validity was acceptable. Internal consistency was adequate in both samples for each subscale and all 12 skills (alpha range 0.60-0.81). This study has provided preliminary evidence for instrument reliability and face validity. This enables future alignment between the measurement of perceived and actual fundamental movement skill competence in young children. Crown Copyright © 2014. Published by Elsevier Ltd.

Full Text Available In order to adjust personality measurements to children’s developmental level, we constructed the Pictorial Personality Traits Questionnaire for Children (PPTQ-C. To validate the measure, we conducted a study with a total group of 1028 children aged between 7 and 13 years old. Structural validity was established through Exploratory Structural Equation Model. Criterion validity was confirmed with a multitrait-multimethod analysis for which we introduced the children’s self-assessment scores from the Big Five Questionnaire for Children. Despite some problems with reliability, one can conclude that the PPTQ-C can be a valid instrument for measuring personality traits, particularly in a group of young children (aged approximately 7 to 10 years.

2013-01-01

The purpose of this review is to illustrate and discuss the spectrum of imaging findings, particularly computed tomography (CT), of blunt and penetrating renal trauma, based on our own materials, according to the American Association for Surgery of Trauma (AAST) renal injury grading scale. The article also indicates the conditions in which interventional radiology procedures can be applied for the management of renal trauma. Cases for this pictorial review were selected from the imaging material collected at the Radiology Department of Hamad Medical Corporation during a 14-year period from 1999 to 2012. The material includes 176 cases (164 males and 12 females) with confirmed blunt or penetrating renal trauma. Following abdominal trauma, all patients had a CT examination performed on admission to the hospital and/or during hospitalization. The most representative and illustrative cases of renal trauma were reviewed according to CT findings and were categorized according to the AAST grading system. The review describes a spectrum of imaging presentations with special emphasis on the 5 grades of renal injury on a CT according to the AAST scale. The most representative cases were illustrated and discussed with indications of possible interventional radiology treatment. Two groups of patients not included in the AAST grading system were presented separately: those with preexisting renal abnormalities and those with sustained iatrogenic renal injury. Proper application of renal trauma grading scale is essential for selecting the patients for conservative treatment, surgery or interventional radiology procedure

Full Text Available Medicine is an ever changing field and interventional radiology (IR procedures are becoming increasingly popular because of high efficacy and its minimally invasive nature of the procedure. Management of disease processes in the extra cranial head and neck (ECHN has always been a challenge due to the complex anatomy of the region. Cross sectional imaging of the ECHN has grown and evolved tremendously and occupies a pivotal and integral position in the clinical management of variety of head and neck pathologies. Advances in angiographic technologies including flat panel detector systems, biplane, and 3-dimensional rotational angiography have consolidated and expanded the role of IR in the management of various ECHN pathologies. The ECHN is at cross roads between the origins of great vessels and the cerebral vasculature. Thorough knowledge of functional and technical aspects of neuroangiography is essential before embarking on head and neck vascular interventions. The vessels of the head and neck can be involved by infectious and inflammatory conditions, get irradiated during radiotherapy and injured due to trauma or iatrogenic cause. The ECHN is also a common site for various hypervascular neoplasms and vascular malformations, which can be treated with endovascular and percutaneous embolization. This pictorial essay provides a review of variety of ECHN pathologies which were managed by various IR procedures using different approaches.

Full Text Available Ms. I.33 is not only the oldest of the known fencing treatises in European context, it is also the only one showing a woman fighting equally with contemporary men. The author presents her research about the garments this female fencer wears, including her shirt, dress and overdress, hairstyle and footwear. Special consideration is given to the questions whether Walpurgis wears a belt, the length and hem circumference of her garments as well as the methods of draping them in the way depicted. The results of the analysis are compared with contemporary pictorial and archaeological sources of the early 14th century. Some personal insights gathered by the author while fighting in this kind of clothes shed light on the possibilities of moving without being disturbed by them. The clothes and hairstyle worn by Walpurgis, give clues about her social status and thus help to understand the context and dating of the whole manuscript.

Non-alcoholic fatty liver disease is the most common cause of chronic liver disease and affects nearly one-third of US population. With the increasing trend of obesity in the population, associated fatty change in the liver will be a common feature observed in imaging studies. Fatty liver causes changes in liver parenchyma appearance on imaging modalities including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) and may affect the imaging characteristics of focal liver lesions (FLLs). The imaging characteristics of FLLs were classically described in a non-fatty liver. In addition, focal fatty change and focal fat sparing may also simulate FLLs. Knowledge of characteristic patterns of fatty change in the liver (diffuse, geographical, focal, subcapsular, and perivascular) and their impact on the detection and characterization of FLL is therefore important. In general, fatty change may improve detection of FLLs on MRI using fat suppression sequences, but may reduce sensitivity on a single-phase (portal venous) CT and conventional ultrasound. In patients with fatty liver, MRI is generally superior to ultrasound and CT for detection and characterization of FLL. In this pictorial essay, we describe the imaging patterns of fatty change in the liver and its effect on detection and characterization of FLLs on ultrasound, CT, MRI, and PET.

A combination of positron emission tomography (PET) with 18F-labeled fluoro-2-deoxyglucose ({sup 18}F-FDG) and computed tomography ({sup 18}F-FDG-PET/CT) has increasingly become a widely used imaging modality for the diagnosis and management of head and neck cancer. On the basis of both recent literature and our professional experience, we present a set of principles with pictorial illustrations and clinical applications of FDG-PET/CT in the evaluation and management planning of squamous cell carcinoma of the oral cavity and oropharynx. We feel that this paper will be of interest and will aid the learning of oral and maxillofacial radiology trainees and practitioners.

Susceptibility-weighted imaging (SWI) is a novel magnetic resonance (MR) technique that exploits the magnetic susceptibility differences of various tissues, such as blood, iron and calcification. This pictorial review covers many clinical conditions illustrating its usefulness. SWI consists of using both magnitude and phase images from a high-resolution, three-dimensional fully velocity-compensated gradient echo sequence. Phase mask is created from the MR phase images, and multiplying these with the magnitude images increase the conspicuity of the smaller veins and other sources of susceptibility effects, which is depicted using minimal intensity projection (minIP). The phase images are useful in differentiating between diamagnetic and paramagnetic susceptibility effects of calcium and blood, respectively. This unique MR sequence will help in detecting occult low flow vascular lesions, calcification and cerebral microbleed in various pathologic conditions and aids in characterizing tumors and degenerative diseases of the brain. This sequence also can be used to visualize normal brain structures with conspicuity. Susceptibility-weighted imaging is useful in differentiating and characterizing diverse brain pathologies.

DUST DISTRIBUTION IN THE β PICTORIS CIRCUMSTELLAR DISKS

Ahmic, Mirza; Croll, Bryce; Artymowicz, Pawel

2009-01-01

We present three-dimensional models of dust distribution around β Pictoris that produce the best fits to the Hubble Space Telescope/Advanced Camera for Surveys' images obtained by Golimowski and coworkers. We allow for the presence of either one or two separate axisymmetric dust disks. The density models are analytical, radial two power laws joined smoothly at a crossover radius with density exponentially decreasing away from the midplane of the disks. Two-disk models match the data best, yielding a reduced χ 2 of ∼1.2. Our two-disk model reproduces many of the asymmetries reported in the literature and suggests that it is the secondary (tilted) disk which is largely responsible for them. Our model suggests that the secondary disk is not constrained to the inner regions of the system (extending out to at least 250 AU) and that it has a slightly larger total area of dust than the primary, as a result of slower falloff of density with radius and height. This surprising result raises many questions about the origin and dynamics of such a pair of disks. The disks overlap, but can coexist owing to their low optical depths and therefore long mean collision times. We find that the two disks have dust replenishment times on the order of 10 4 yr at ∼100 AU, hinting at the presence of planetesimals that are responsible for the production of second generation dust. A plausible conjecture, which needs to be confirmed by physical modeling of the collisional dynamics of bodies in the disks, is that the two observed disks are derived from underlying planetesimal disks; such disks would be anchored by the gravitational influence of planets located at less than 70 AU from β Pic that are themselves in slightly inclined orbits.

Effect of pictorial depth cues, binocular disparity cues and motion parallax depth cues on lightness perception in three-dimensional virtual scenes.

Full Text Available Surface lightness perception is affected by scene interpretation. There is some experimental evidence that perceived lightness under bi-ocular viewing conditions is different from perceived lightness in actual scenes but there are also reports that viewing conditions have little or no effect on perceived color. We investigated how mixes of depth cues affect perception of lightness in three-dimensional rendered scenes containing strong gradients of illumination in depth.Observers viewed a virtual room (4 m width x 5 m height x 17.5 m depth with checkerboard walls and floor. In four conditions, the room was presented with or without binocular disparity (BD depth cues and with or without motion parallax (MP depth cues. In all conditions, observers were asked to adjust the luminance of a comparison surface to match the lightness of test surfaces placed at seven different depths (8.5-17.5 m in the scene. We estimated lightness versus depth profiles in all four depth cue conditions. Even when observers had only pictorial depth cues (no MP, no BD, they partially but significantly discounted the illumination gradient in judging lightness. Adding either MP or BD led to significantly greater discounting and both cues together produced the greatest discounting. The effects of MP and BD were approximately additive. BD had greater influence at near distances than far.These results suggest the surface lightness perception is modulated by three-dimensional perception/interpretation using pictorial, binocular-disparity, and motion-parallax cues additively. We propose a two-stage (2D and 3D processing model for lightness perception.

Aims: We carried out high-resolution spectroscopy and BV(I)C photometric monitoring of the two fastest late-type rotators in the nearby β Pictoris moving group, HD 199143 (F7V) and CD-64°1208 (K7V). The motivation for this work is to investigate the rotation periods and photospheric spot patterns of these very young stars, with a longer term view to probing the evolution of rotation and magnetic activity during the early phases of main-sequence evolution. We also aim to derive information on key physical parameters, such as rotational velocity and rotation period. Methods: We applied maximum entropy (ME) and Tikhonov regularizing (TR) criteria to derive the surface spot map distributions of the optical modulation observed in HD 199143 (F7 V) and CD-64°1208 (K7 V). We also used cross-correlation techniques to determine stellar parameters such as radial velocities and rotational velocities. Lomb-Scargle periodograms were used to obtain the rotational periods from differential magnitude time series. Results: We find periods and inclinations of 0.356 days and 21.5 deg for HD 199143, and 0.355 days and 50.1 deg for CD-64°1208. The spot maps of HD 199143 obtained from the ME and TR methods are very similar, although the latter gives a smoother distribution of the filling factor. Maps obtained at two different epochs three weeks apart show a remarkable increase in spot coverage amounting to ~7% of the surface of the photosphere over a time period of only ~20 days. The spot maps of CD-64°1208 from the two methods show good longitudinal agreement, whereas the latitude range of the spots is extended to cover the whole visible hemisphere in the TR map. The distributions obtained from the first light curve of HD 199143 show the presence of an extended and asymmetric active longitude with the maximum filling factor at longitude ~325°. A secondary active longitude is present at ~100°. The spotted area distributions on CD-64°1208 show two active longitudes separated by

Imaging in the major planes (horizontal, coronal, and sagittal) of the uterus is important for determining anatomy and allowing the findings to be standardized, and for evaluating and diagnosing different pathological conditions in clinical practice. Examination of the coronal plane is an important step in identifying uterine pathologies and their relationships to the endometrial canal. Three-dimensional (3D) ultrasound reveals the normal anatomy better and improves the depiction of abnormal anatomy, as the coronal plane of the uterus can easily be obtained using 3D reconstruction techniques. Our pictorial essay demonstrates that adding 3D ultrasound to a routine gynecological workup can be beneficial for clinicians, enabling a precise diagnosis to be made. In addition, the volumes obtained and stored by 3D ultrasound can allow students or residents to become more familiar with normal and abnormal pelvic structures. Clin.

MAGNETO-CONVECTION AND LITHIUM AGE ESTIMATES OF THE β PICTORIS MOVING GROUP

International Nuclear Information System (INIS)

Macdonald, J.; Mullan, D. J.

2010-01-01

Although the means of the ages of stars in young groups determined from Li depletion often agree with mean ages determined from Hertzsprung-Russell (H-R) diagram isochrones, there are often statistically significant differences in the ages of individual stars determined by the two methods. We find that inclusion of the effects of inhibition of convection due to the presence of magnetic fields leads to consistent ages for the individual stars. We illustrate how age consistency arises by applying our results to the β Pictoris moving group (BPMG). We find that, although magnetic inhibition of convection leads to increased ages from the H-R diagram isochrones for all stars, Li ages are decreased for fully convective M stars and increased for stars with radiative cores. Our consistent age determination for BPMG of 40 Myr is larger than previous determinations by a factor of about two. We have also considered models in which the mixing length ratio is adjusted to give consistent ages. We find that our magneto-convection models, which give quantitative estimates of magnetic field strength, provide a viable alternative to models in which the effects of magnetic fields (and other processes) are accounted for by reducing the mixing length ratio.

2015-01-01

Immunoglobulin G4 (IgG4)-related kidney disease (IgG4-KD) has recently been demonstrated to be an important part of IgG4-related sclerosing disease (IgG4-SD). However, since IgG4-KD is still relatively unfamiliar to radiologists and physicians as compared to IgG4-SD involving other organs, it could, therefore, be easily missed. In this article, we present a comprehensive pictorial review of IgG4-KD with regards to the imaging spectrum, mimickers, and clinicopathologic characteristics, based on our clinical experience with 48 patients during the past 13 years, as well as a literature review. Awareness of the broad imaging spectrum of IgG4-KD and differential diagnosis from its mimickers will thus facilitate its early diagnosis and treatment

Full Text Available The analysis of works of art has is of educational interest in medicine because it allows students to initiate the skill of observation, necessary to educate the gaze in a thorough and systematic clinical exploration. With the aim of exploring the possible formative role of analysis, documentation, description of works of art and their subsequent communication 150 medical students per course participated. Students achieved a grade of 8.5 or above out of 10 in the communication and documentation exercises. They also identified, in more than 90% of cases, elements related to medicine, but were less efficient at relating the pictorial, figurative or accessory elements, or transferring at present the history reflected in the work of art. More than 60% of the students consider that the activity has a formative interest.

Competing models of the factorial structure of the Pictorial Scale of Perceived Competence and Social Acceptance (PSPCSA) were tested for fit using multisample confirmatory factor analysis. The best fitting model was tested for invariance (a) across samples of middle-class (n = 251) and economically disadvantaged (Head Start, n = 117) kindergarten children (whose ages ranged from 67 to 86 months), and (b) over time (at the end of preschool and kindergarten) for the Head Start sample. For kindergarten children, regardless of socioeconomic status, the factor structure of the PSPCSA was consistent with the 2-factor model of Competence and Acceptance. This model also fit reasonably well for Head Start children at the end of their preschool year. However, in addition to providing broad support for the dimensionality of the measure, our findings highlight important concerns about the PSPCSA.

2011-05-01

Eight participants with probable Alzheimer's disease (AD) were trained to recall names of countries using the spaced-retrieval memory intervention. Six training sessions were administered on alternate days over a 2-week period. Half of the participants studied a target country alone and the other half studied a target country along with eight distractor countries. Training stimuli appeared in text-only format in half of the sessions and text with a color photograph of the country in the other sessions. On each trial, participants selected the target at increasingly longer retention intervals, contingent upon successful recall. Results indicated that the mean proportion of correct trials and longest duration achieved increased across training sessions, confirming the success of the spaced-retrieval intervention. Pictorial illustrations enhanced explicit memory for target country names. Implications of these data for current views on memory remediation in cognitively impaired older adults are discussed.

Riddle, Philip J; Newman-Norlund, Roger D; Baer, Jessica; Thrasher, James F

2016-11-01

In order to improve our understanding of how pictorial health warning labels (HWLs) influence smoking behavior, we examined whether brain activity helps to explain smoking behavior above and beyond self-reported effectiveness of HWLs. We measured the neural response in the ventromedial prefrontal cortex (vmPFC) and the amygdala while adult smokers viewed HWLs. Two weeks later, participants' self-reported smoking behavior and biomarkers of smoking behavior were reassessed. We compared multiple models predicting change in self-reported smoking behavior (cigarettes per day [CPD]) and change in a biomarkers of smoke exposure (expired carbon monoxide [CO]). Brain activity in the vmPFC and amygdala not only predicted changes in CO, but also accounted for outcome variance above and beyond self-report data. Neural data were most useful in predicting behavioral change as quantified by the objective biomarker (CO). This pattern of activity was significantly modulated by individuals' intention to quit. The finding that both cognitive (vmPFC) and affective (amygdala) brain areas contributed to these models supports the idea that smokers respond to HWLs in a cognitive-affective manner. Based on our findings, researchers may wish to consider using neural data from both cognitive and affective networks when attempting to predict behavioral change in certain populations (e.g. cigarette smokers). © The Author (2016).

Partial epilepsy: A pictorial review of 3 TESLA magnetic resonance imaging features

Directory of Open Access Journals (Sweden)

2015-09-01

Full Text Available Epilepsy is a disease with serious consequences for patients and society. In many cases seizures are sufficiently disabling to justify surgical evaluation. In this context, Magnetic Resonance Imaging (MRI is one of the most valuable tools for the preoperative localization of epileptogenic foci. Because these lesions show a large variety of presentations (including subtle imaging characteristics, their analysis requires careful and systematic interpretation of MRI data. Several studies have shown that 3 Tesla (T MRI provides a better image quality than 1.5 T MRI regarding the detection and characterization of structural lesions, indicating that high-field-strength imaging should be considered for patients with intractable epilepsy who might benefit from surgery. Likewise, advanced MRI postprocessing and quantitative analysis techniques such as thickness and volume measurements of cortical gray matter have emerged and in the near future, these techniques will routinely enable more precise evaluations of such patients. Finally, the familiarity with radiologic findings of the potential epileptogenic substrates in association with combined use of higher field strengths (3 T, 7 T, and greater and new quantitative analytical post-processing techniques will lead to improvements regarding the clinical imaging of these patients. We present a pictorial review of the major pathologies related to partial epilepsy, highlighting the key findings of 3 T MRI.

Edge enhancement improves disruptive camouflage by emphasising false edges and creating pictorial relief.

Science.gov (United States)

Egan, John; Sharman, Rebecca J; Scott-Brown, Kenneth C; Lovell, Paul George

2016-12-06

Disruptive colouration is a visual camouflage composed of false edges and boundaries. Many disruptively camouflaged animals feature enhanced edges; light patches are surrounded by a lighter outline and/or a dark patches are surrounded by a darker outline. This camouflage is particularly common in amphibians, reptiles and lepidopterans. We explored the role that this pattern has in creating effective camouflage. In a visual search task utilising an ultra-large display area mimicking search tasks that might be found in nature, edge enhanced disruptive camouflage increases crypsis, even on substrates that do not provide an obvious visual match. Specifically, edge enhanced camouflage is effective on backgrounds both with and without shadows; i.e. this is not solely due to background matching of the dark edge enhancement element with the shadows. Furthermore, when the dark component of the edge enhancement is omitted the camouflage still provided better crypsis than control patterns without edge enhancement. This kind of edge enhancement improved camouflage on all background types. Lastly, we show that edge enhancement can create a perception of multiple surfaces. We conclude that edge enhancement increases the effectiveness of disruptive camouflage through mechanisms that may include the improved disruption of the object outline by implying pictorial relief.

Autobiographical memory specificity in response to verbal and pictorial cues in clinical depression.

Ridout, Nathan; Dritschel, Barbara; Matthews, Keith; O'Carroll, Ronan

2016-06-01

Depressed individuals have been consistently shown to exhibit problems in accessing specific memories of events from their past and instead tend to retrieve categorical summaries of events. The majority of studies examining autobiographical memory changes associated with psychopathology have tended to use word cues, but only one study to date has used images (with PTSD patients). to determine if using images to cue autobiographical memories would reduce the memory specificity deficit exhibited by patients with depression in comparison to healthy controls. Twenty-five clinically depressed patients and twenty-five healthy controls were assessed on two versions of the autobiographical memory test; cued with emotional words and images. Depressed patients retrieved significantly fewer specific memories, and a greater number of categorical, than did the controls. Controls retrieved a greater proportion of specific memories to images compared to words, whereas depressed patients retrieved a similar proportion of specific memories to both images and words. no information about the presence and severity of past trauma was collected. results suggest that the overgeneral memory style in depression generalises from verbal to pictorial cues. This is important because retrieval to images may provide a more ecologically valid test of everyday memory experiences than word-cued retrieval.. Copyright © 2016 Elsevier Ltd. All rights reserved.

Fluorine-18-sodium fluoride (F-NaF) PET/CT is a relatively new and high-resolution bone imaging modality. Since the use of F-NaF PET/CT has been increasing, it is important to accurately assess the images and be aware of normal distribution and major artifacts. In this pictorial review article, we will describe the normal uptake patterns of F-NaF in the bone tissues, particularly in complex structures, as well as its physiologic soft tissue distribution and certain artifacts seen on F-NaF PET/CT images.

Leiomyoma affects up to 50% of fertile women, leading to morbidity such as bleeding or pain. The effect of symptomatic leiomyoma on the productivity of employed women is understudied. The present study investigates productivity loss in a Swedish setting in women with symptomatic leiomyoma compared to healthy women. Women seeking care for leiomyoma and heavy menstrual bleeding (HMB) were recruited at nine Swedish sites. Healthy controls with self-perceived mild to normal menstruation were recruited at routine visits. Cases and controls were employed without option to work from home. After recruitment, all women reported the work productivity and activity impairment (WPAI) questionnaire, the pictorial blood assessment chart (PBAC) and pain on the visual analog scale (VAS). Women with symptomatic leiomyoma (n = 88) missed more working time during menses compared to asymptomatic controls (n = 34): 7.6 vs 0.2% p = 0.003. The proportion of impairment while working was also significantly higher in women with symptomatic leiomyoma (43.8 vs 12.1% p100). Symptomatic leiomyoma leads to loss of working hours as well as loss of productivity during working hours, and affects women in other daily activities. Increased awareness of the impact of leiomyomas on women's lives is needed, and timely and appropriate management of the symptomatic leiomyomas could improve work productivity and quality of life.

A study of village women in Haiti which presents baseline data from their responses to stylized health education pictures is reported. The study questioned the concept that pictorial messages were accurately recognized and self-explanatory to nonliterate Haitian village women. The investigator, who used a descriptive survey, sought answers to a major and a related question: what do nonliterate Haitian village women recognize in selected health education pictures; and are their differences in picture recognition traceable to the complexity of the pictures. There were 110 women (25 from a mountain village, 25 from a plains village, 25 from a seacoast village, and 35 urban dwellers) who responded to 9 health education pictures. The women ranged in age from 18-80 years of age; 32 (29%) had gone to school for a range of an "unknown time" to 8 years. 47% of those who had gone to school indicated that they could read. The investigator rated the verbatim responses to the pictures for accuracy as: accurate, overinclusive, underinclusive, inaccurate, and do not know. The quantitative analysis of this data revealed that the accuracy levels decreased as the complexity level increased. This is best shown in the 129 (39%) accurate responses in the low level; 6 (1.8%) in the moderate level; and no accurate responses in the high complexity level. An unexpected finding was the highest number of inaccurate responses (n = 83, 25.1%) found in the low complexity level, while the moderate and high levels both showed 36 (10.8%). In addition to the differences in accuracy in picture recognition based on picture complexity, there were significant differences on the chi-square test which confirmed the assertion of the question that picture recognition is traceable to the complexity of the picture. These findings are consistent with the picture complexity studies of Holmes, Jelliffe, and Kwansa.

This study used eye tracking to investigate the allocation of attention to multimodal stimuli during an incidental learning situation, as well as its impact on subsequent explicit learning. Participants were exposed to foreign language (FL) auditory words on their own, in conjunction with written native language (NL) translations, or with both written NL translations and pictures. Incidental acquisition of FL words was assessed the following day through an explicit learning task where participants learned to recognize translation equivalents, as well as one week later through recall and translation recognition tests. Results showed higher accuracy scores in the explicit learning task for FL words presented with meaning during incidental learning, whether written meaning or both written meaning and picture, than for FL words presented auditorily only. However, participants recalled significantly more FL words after a week delay if they had been presented with a picture during incidental learning. In addition, the time spent looking at the pictures during incidental learning significantly predicted recognition and recall scores one week later. Overall, results demonstrated the impact of exposure to multimodal stimuli on subsequent explicit learning, as well as the important role that pictorial information can play in incidental vocabulary acquisition.

A COMPREHENSIVE DUST MODEL APPLIED TO THE RESOLVED BETA PICTORIS DEBRIS DISK FROM OPTICAL TO RADIO WAVELENGTHS

We investigate whether varying the dust composition (described by the optical constants) can solve a persistent problem in debris disk modeling—the inability to fit the thermal emission without overpredicting the scattered light. We model five images of the β Pictoris disk: two in scattered light from the Hubble Space Telescope ( HST )/Space Telescope Imaging Spectrograph at 0.58 μ m and HST /Wide Field Camera 3 (WFC 3) at 1.16 μ m, and three in thermal emission from Spitzer /Multiband Imaging Photometer for Spitzer (MIPS) at 24 μ m, Herschel /PACS at 70 μ m, and Atacama Large Millimeter/submillimeter Array at 870 μ m. The WFC3 and MIPS data are published here for the first time. We focus our modeling on the outer part of this disk, consisting of a parent body ring and a halo of small grains. First, we confirm that a model using astronomical silicates cannot simultaneously fit the thermal and scattered light data. Next, we use a simple generic function for the optical constants to show that varying the dust composition can improve the fit substantially. Finally, we model the dust as a mixture of the most plausible debris constituents: astronomical silicates, water ice, organic refractory material, and vacuum. We achieve a good fit to all data sets with grains composed predominantly of silicates and organics, while ice and vacuum are, at most, present in small amounts. This composition is similar to one derived from previous work on the HR 4796A disk. Our model also fits the thermal spectral energy distribution, scattered light colors, and high-resolution mid-IR data from T-ReCS for this disk. Additionally, we show that sub-blowout grains are a necessary component of the halo.

The main goal in meningioma surgery is to achieve complete tumor removal, when possible, while improving or preserving patient neurological functions. Intraoperative imaging guidance is one fundamental tool for such achievement. In this regard, intra-operative ultrasound (ioUS) is a reliable solution to obtain real-time information during surgery and it has been applied in many different aspect of neurosurgery. In the last years, different ioUS modalities have been described: B-mode, Fusion Imaging with pre-operative acquired MRI, Doppler, contrast enhanced ultrasound (CEUS), and elastosonography. In this paper, we present our US based multimodal approach in meningioma surgery. We describe all the most relevant ioUS modalities and their intraoperative application to obtain precise and specific information regarding the lesion for a tailored approach in meningioma surgery. For each modality, we perform a review of the literature accompanied by a pictorial essay based on our routinely use of ioUS for meningioma resection.

Immersive virtual reality techniques present new opportunities for research into consumer behavior. The current study examines whether the increased realism of a virtual store compared to pictorial (2D) stimuli elicits consumer behavior that is more in line with behavior in a physical store. We examine the number, variety, and type of products selected, amount of money spent, and responses to price promotions and shelf display, in three product categories (fruit & vegetables, milk, and biscuits). We find that virtual reality elicits behavior that is more similar to behavior in the physical store compared to the picture condition for the number of products selected (Milk: M store  = 1.19, M virtual  = 1.53, M pictures  = 2.58) and amount of money spent (Milk: M store  = 1.27, M virtual  = 1.53, M pictures  = 2.60 Euro), and for the selection of products from different areas of the shelf, both vertically (purchases from top shelves, milk and biscuits: P store  = 21.6%, P virtual  = 33.4%, P pictures  = 50.0%) and horizontally (purchase from left shelf, biscuits: P store  = 35.5%, P virtual  = 53.3%, P pictures  = 66.7%). This indicates that virtual reality can improve realism in responses to shelf allocation. Virtual reality was not able to diminish other differences between lab and physical store: participants bought more products and spent more money (for biscuits and fruit & vegetables), bought more national brands, and responded more strongly to price promotions in both virtual reality and pictorial representations than in the physical store. Implications for the use of virtual reality in studies of consumer food choice behavior as well as for future improvement of virtual reality techniques are discussed. Copyright © 2016 Elsevier Ltd.

Primary central nervous system lymphoma (PCNSL) is an uncommon but important variant of non-Hodgkin lymphoma and represents up to 6% of all primary central nervous system (CNS) malignancies. Recognition of this entity by radiologist on MRI may avoid unnecessary neurosurgical resection and redirect to biopsy. The pretreatment MRI of patients with biopsy proven PCNSL from the last 5 years at our institution was reviewed. Selected examples were used to construct a pictorial essay to illustrate some of the typical and atypical MR features of PCNSL. MRI of other CNS conditions with imaging similarities to PCNSL was included to demonstrate possible mimics. The typical features of PCNSL lymphoma are intra-axial homogenous single or multiple contrast enhancing lesions, with marked surrounding oedema and restricted diffusion, usually contacting a cerebrospinal fluid (CSF) surface. Necrosis, peripheral enhancement, haemorrhage or calcification are unusual and other diagnoses should be considered if any of these features are present. Potential mimics include high grade glioma, infarcts, metastatic disease, demyelination, abscess and secondary lymphoma. Careful assessment of the MR features and correlation with the clinical findings should enable the radiologists to raise the possibility of PCNSL and minimise the risk of unnecessary resection.

Neuronal correlate of pictorial short-term memory in the primate temporal cortexYasushi Miyashita

Miyashita, Yasushi; Chang, Han Soo

It has been proposed that visual-memory traces are located in the temporal lobes of the cerebral cortex, as electric stimulation of this area in humans results in recall of imagery1. Lesions in this area also affect recognition of an object after a delay in both humans2,3 and monkeys4-7 indicating a role in short-term memory of images8. Single-unit recordings from the temporal cortex have shown that some neurons continue to fire when one of two or four colours are to be remembered temporarily9. But neuronal responses selective to specific complex objects10-18 , including hands10,13 and faces13,16,17, cease soon after the offset of stimulus presentation10-18. These results led to the question of whether any of these neurons could serve the memory of complex objects. We report here a group of shape-selective neurons in an anterior ventral part of the temporal cortex of monkeys that exhibited sustained activity during the delay period of a visual short-term memory task. The activity was highly selective for the pictorial information to be memorized and was independent of the physical attributes such as size, orientation, colour or position of the object. These observations show that the delay activity represents the short-term memory of the categorized percept of a picture.

β Pictoris (A5V) possesses a circumstellar disk of gas and dust which is oriented edge-on to Earth. Possibly a planet may be indirectly responsible for spectroscopic events, presently interpreted as the signature of the vaporisation of comet-like bodies when grazing the star, and may have cleared up dust particles in the inner zone. Previous coronographic studies coupled with IRAS and ground based IR observations also seem to indicate that the inner regions of the disk may be possibly dust free. We have extended the coronographic studies closer to the star in order to directly observe this zone, through a different observational technique based on the use of an anti- blooming CCD. These new observations, recorded at La Silla (Chile), revealed the structure of the disk down to two arcsec from the star (30 AU from the star). A different nature of dust particles seems to be present in the inner regions of the disk, in possible relation with a planetary formation process. Also an inverted asymmetry is observed in the inner region of the disk when compared to the outer one, a structure possibly related to a non homogeneous distribution of the dust within the disk.

High resolution manometry is the current technology used to the study of esophageal motility and is replacing conventional manometry in important centers for esophageal motility with parameters used on esophageal motility, following the Chicago Classification. This classification unifies high resolution manometry interpretation and classifies esophageal disorders. This review shows, in a pictorial presentation, the new parameters established by the Chicago Classification, version 3.0, aimed to allow an easy comprehension and interpretation of high resolution manometry. Esophageal manometries performed by the authors were reviewed to select illustrative tracings representing Chicago Classification parameters. The parameters are: Esophagogastric Morphology, that classifies this junction according to its physiology and anatomy; Integrated Relaxation Pressure, that measures the lower esophageal sphincter relaxation; Distal Contractile Integral, that evaluates the contraction vigor of each wave; and, Distal Latency, that measures the peristalsis velocity from the beginning of the swallow to the epiphrenic ampulla. Clinical applications of these new concepts is still under evaluation. Mostrar, de forma pictórica, os novos parâmetros compilados na versão 3.0 da Classificação de Chicago, buscando facilitar a compreensão e interpretação da manometria de alta resolução. Foram revistas as manometrias da casuística dos autores e selecionados os traçados representativos dos parâmetros da Classificação de Chicago. Entre os parâmetros apresentados foram considerados a Morfologia da Transição Gastroesofágica, que classifica o segmento de acordo com sua fisiologia e anatomia; a Integral da Pressão de Relaxamento, que mede o relaxamento do esfíncter esofagiano inferior; a Integral Contrátil Distal, que avalia o vigor contrátil da onda peristáltica; e, a Latência Distal, que mede o tempo da peristalse, desde o início da deglutição até a ampola epifr

Hanse, J J; Forsman, M

2001-02-01

A method for psychosocial evaluation of potentially stressful or unsatisfactory situations in manual work was developed. It focuses on subjective responses regarding specific situations and is based on interactive worker assessment when viewing video recordings of oneself. The worker is first video-recorded during work. The video is then displayed on the computer terminal, and the filmed worker clicks on virtual controls on the screen whenever an unsatisfactory psychosocial situation appears; a window of questions regarding psychological demands, mental strain and job control is then opened. A library with pictorial information and comments on the selected situations is formed in the computer. The evaluation system, called PSIDAR, was applied in two case studies, one of manual materials handling in an automotive workshop and one of a group of workers producing and testing instrument panels. The findings indicate that PSIDAR can provide data that are useful in a participatory ergonomic process of change.

Health anxiety and attentional bias: the time course of vigilance and avoidance in light of pictorial illness information.

Cognitive-behavioral models of health anxiety stress the importance of selective attention not only towards internal but also towards external health threat related stimuli. Yet, little is known about the time course of this attentional bias. The current study investigates threat related attentional bias in participants with varying degrees of health anxiety. Attentional bias was assessed using a visual dot-probe task with health-threat and neutral pictures at two exposure durations, 175ms and 500ms. A baseline condition was added to the dot-probe task to dissociate indices of vigilance towards threat and difficulties to disengage from threat. Substantial positive correlations of health anxiety, anxiety sensitivity, and absorption with difficulties to disengage from threat were detected at 500ms exposure time. At an early stage (i.e., at 175ms exposure time), we found significant positive correlations of health anxiety and absorption with orientation towards threat. Results suggest a vigilance avoidance pattern of selective attention associated with pictorial illness related stimuli in health anxiety. Copyright © 2011 Elsevier Ltd. All rights reserved.

Pictorial review: Electron beam computed tomography and multislice spiral computed tomography for cardiac imaging

Electron beam computed tomography (EBCT) revolutionized cardiac imaging by combining a constant high temporal resolution with prospective ECG triggering. For years, EBCT was the primary technique for some non-invasive diagnostic cardiac procedures such as calcium scoring and non-invasive angiography of the coronary arteries. Multislice spiral computed tomography (MSCT) on the other hand significantly advanced cardiac imaging through high volume coverage, improved spatial resolution and retrospective ECG gating. This pictorial review will illustrate the basic differences between both modalities with special emphasis to their image quality. Several experimental and clinical examples demonstrate the strengths and limitations of both imaging modalities in an intraindividual comparison for a broad range of diagnostic applications such as coronary artery calcium scoring, coronary angiography including stent visualization as well as functional assessment of the cardiac ventricles and valves. In general, our examples indicate that EBCT suffers from a number of shortcomings such as limited spatial resolution and a low contrast-to-noise ratio. Thus, EBCT should now only be used in selected cases where a constant high temporal resolution is a crucial issue, such as dynamic (cine) imaging. Due to isotropic submillimeter spatial resolution and retrospective data selection MSCT seems to be the non-invasive method of choice for cardiac imaging in general, and for assessment of the coronary arteries in particular. However, technical developments are still needed to further improve the temporal resolution in MSCT and to reduce the substantial radiation exposure

The comparability of viewers' responses to slide-projected and computer-generated images of nine paintings by renowned artists to those obtained from individuals experiencing the originals in the galleries of the New York Metropolitan Museum of Art was investigated. The influence of training in the visual arts upon evaluative judgments made under the three presentation formats was also assessed. Specifically, art-trained and untrained participants in each format condition rated each artwork on sixteen measures of physical and structural characteristics, novelty of content, and aesthetic qualities. Analyses revealed significant differences in the judged hedonic value of the originals as contrasted with the two types of reproduction, whereas trained and untrained participants' evaluations of the pictorial qualities of the artworks were comparable across presentation formats. Findings are discussed in terms of a facsimile-accommodation hypothesis proposed by the authors.

COOL YOUNG STARS IN THE NORTHERN HEMISPHERE: β PICTORIS AND AB DORADUS MOVING GROUP CANDIDATES

2012-01-01

As part of our continuing effort to identify new, low-mass members of nearby, young moving groups (NYMGs), we present a list of young, low-mass candidates in the northern hemisphere. We used our proven proper-motion selection procedure and ROSAT X-ray and GALEX-UV activity indicators to identify 204 young stars as candidate members of the β Pictoris and AB Doradus NYMGs. Definitive membership assignment of a given candidate will require a measurement of its radial velocity and distance. We present a simple system of indices to characterize the young candidates and help prioritize follow-up observations. New group members identified in this candidate list will be high priority targets for (1) exoplanet direct imaging searches, (2) the study of post-T-Tauri astrophysics, (3) understanding recent local star formation, and (4) the study of local galactic kinematics. Information available now allows us to identify eight likely new members in the list. Two of these, a late-K and an early-M dwarf, we find to be likely members of the β Pic group. The other six stars are likely members of the AB Dor moving group. These include an M dwarf triple system, and three very cool objects that may be young brown dwarfs, making them the lowest-mass, isolated objects proposed in the AB Dor moving group to date.

Although there is much talk about shared decision making and individualized goal setting, there is a lack of knowledge and knowhow in their realization in daily clinical practice. There is a lack in tools for easy applicable tools to ameliorate person-centred individualized goal setting processes. In three selected psychiatric inpatients the semistructured, theory driven use of PRISM (Pictorial Representation of Illness and Self Measure) in patients with complex psychiatric problems is presented and discussed. PRISM sustains a person-centred individualized process of goal setting and treatment and reinforces the active participation of patients. The process of visualisation and synchronous documentation is validated positively by patients and clinicians. The visual goal setting requires 30 to 45 minutes. In patients with complex psychiatric illness PRISM was used successfully to ameliorate individual goal setting. Specific effects of PRISM-visualisation are actually evaluated in a randomized controlled trial.

Selective attention and avoidance on a pictorial cueing task during stress in clinically anxious and depressed participants.

Ellenbogen, Mark A; Schwartzman, Alex E

2009-02-01

Although it is well established that attentional biases exist in anxious populations, the specific components of visual orienting towards and away from emotional stimuli are not well delineated. The present study was designed to examine these processes. We used a modified spatial cueing task to assess the speed of engagement and disengagement from supraliminal and masked pictorial cues depicting threat, dysphoria, or neutral content in 36 clinically anxious, 41 depressed and 41 control participants. Participants were randomly assigned to a stress or neutral condition. During stress, anxious participants were slow to disengage from masked left hemifield pictures depicting threat or dysphoria, but were quick to disengage from supraliminal threat pictures. Information processing in anxious participants during stress was characterized by early selective attention of emotional stimuli, occurring prior to full conscious awareness, followed by effortful avoidance of threat. Depressed participants were distinct from the anxious group, displaying selective attention for stimuli depicting dysphoria, but not threat, during the neutral condition. In sum, attentional biases in clinical populations are associated with difficulties in the disengagement component of visual orienting. Further, a vigilant-avoidant pattern of attentional bias may represent a strategic attempt to compensate for the early activation of a fear response.

Questing one's personal identity and developing a coherent representation of oneself, the other and the world are major tasks in adolescence. Research showed that a satisfactory resolution of the crisis of adolescence can be favoured by psychological counselling based on artistic mediations. The objective of this study consisted in exploring the effect of music on the pictorial expression of a non clinical sample of female adolescents (N=157) aged from 17 to 28 years. We analysed free drawings realised by the test group with the help of a rating scale constructed in a phenomenological and structural perspective (Schiltz, 2006). The adolescents painted under musical induction. We proposed three different styles of music, i.e. baroque music (Georg Friedrich Händel and Johann Sebastian Bach), classical music (Wolfgang Amadeus Mozart and Ludwig van Beethoven) and polish ethnical music (Kapela ze Wsi Warszawa-Warsaw Village Band). By using non parametric inferential and multi dimensional statistics, we could show that structural characteristics of music styles lead to differences in formal and content variables on the rating scales for the pictures. The results of our exploratory study open some tracks for future research. It would be pertinent to enlarge the population to other categories of age and to investigate the influence of gender.

We report a series of experiments using a pictorial analogy task designed to manipulate relational integration, interference resolution, and active maintenance simultaneously. The difficulty of the problems was varied in terms of the number of relations to be integrated, the need for interference resolution, and the duration of maintenance required to correctly solve the analogy. The participants showed decreases in performance when integrating multiple relations, as compared with a single relation, and when interference resolution was required in solving the analogy. When the participants were required to integrate multiple relations while simultaneously engaged in interference resolution, performance was worse, as compared with problems that incorporated either of these features alone. Maintenance of information across delays in the range of 1-4.5 sec led to greater decrements in visual memory, as compared with analogical reasoning. Misleading information caused interference when it had been necessarily attended to and maintained in working memory and, hence, had to be actively suppressed. However, sources of conflict within information that had not been attended to or encoded into working memory did not interfere with the ongoing controlled information processing required for relational integration. The findings provide evidence that relational integration and interference resolution depend on shared cognitive resources in working memory during analogical reasoning.

It is important to assess young children's perceived Fundamental Movement Skill (FMS) competence in order to examine the role of perceived FMS competence in motivation toward physical activity. Children's perceptions of motor competence may vary according to the culture/country of origin; therefore, it is also important to measure perceptions in different cultural contexts. The purpose was to assess the face validity, internal consistency, test-retest reliability and construct validity of the 12 FMS items in the Pictorial Scale for Perceived Movement Skill Competence for Young Children (PMSC) in a Portuguese sample. Two hundred one Portuguese children (girls, n = 112), 5 to 10 years of age (7.6 ± 1.4), participated. All children completed the PMSC once. Ordinal alpha assessed internal consistency. A random subsamples (n = 47) were reassessed one week later to determine test-retest reliability with Bland-Altman method. Children were asked questions after the second administration to determine face validity. Construct validity was assessed on the whole sample with a Bayesian Structural Equation Modelling (BSEM) approach. The hypothesized theoretical model used the 12 items and two hypothesized factors: object control and locomotor skills. The majority of children correctly identified the skills and could understand most of the pictures. Test-retest reliability analysis was good, with an agreement ration between 0.99 and 1.02. Ordinal alpha values ranged from acceptable (object control 0.73, locomotor 0.68) to good (all FMS 0.81). The hypothesized BSEM model had an adequate fit. The PMSC can be used to investigate perceptions of children's FMS competence. This instrument can also be satisfactorily used among Portuguese children. © 2016 John Wiley & Sons Ltd.

Pornographic picture processing interferes with working memory performance.

Some individuals report problems during and after Internet sex engagement, such as missing sleep and forgetting appointments, which are associated with negative life consequences. One mechanism potentially leading to these kinds of problems is that sexual arousal during Internet sex might interfere with working memory (WM) capacity, resulting in a neglect of relevant environmental information and therefore disadvantageous decision making. In this study, 28 healthy individuals performed 4 experimental manipulations of a pictorial 4-back WM task with neutral, negative, positive, or pornographic stimuli. Participants also rated 100 pornographic pictures with respect to sexual arousal and indicated masturbation urges previous to and following pornographic picture presentation. Results revealed worse WM performance in the pornographic picture condition of the 4-back task compared with the three remaining picture conditions. Furthermore, hierarchical regression analysis indicated an explanation of variance of the sensitivity in the pornographic picture condition by the subjective rating of the pornographic pictures as well as by a moderation effect of masturbation urges. Results contribute to the view that indicators of sexual arousal due to pornographic picture processing interfere with WM performance. Findings are discussed with respect to Internet sex addiction because WM interference by addiction-related cues is well known from substance dependencies.

Food-cue affected motor response inhibition and self-reported dieting success: a pictorial affective shifting task

Full Text Available Behavioral inhibition is one of the basic facets of executive functioning and is closely related to self-regulation. Impulsive reactions, i.e. low inhibitory control, have been associated with higher body-mass-index (BMI, binge eating, and other problem behaviors (e.g. substance abuse, pathological gambling, etc.. Nevertheless, studies which investigated the direct influence of food-cues on behavioral inhibition have been fairly inconsistent. In the current studies, we investigated food-cue affected behavioral inhibition in young women. For this purpose, we used a go/no-go task with pictorial food and neutral stimuli in which stimulus-response mapping is reversed after every other block (affective shifting task. In study 1, hungry participants showed faster reaction times to and omitted fewer food than neutral targets. Low dieting success and higher BMI were associated with behavioral disinhibition in food relative to neutral blocks. In study 2, both hungry and satiated individuals were investigated. Satiation did not influence overall task performance, but modulated associations of task performance with dieting success and self-reported impulsivity. When satiated, increased food craving during the task was associated with low dieting success, possibly indicating a preload-disinhibition effect following food intake. Food-cues elicited automatic action and approach tendencies regardless of dieting success, self-reported impulsivity, or current hunger levels. Yet, associations between dieting success, impulsivity, and behavioral food-cue responses were modulated by hunger and satiation. Future research investigating clinical samples and including other salient non-food stimuli as control category is warranted.

Dementia, caused by irreversible neurodegenerative disorders such as Alzheimer's disease or reversible non-degenerative conditions, is rapidly becoming one of the most alarming health problems in our aging society. This cognitive disorder associated with a multitude of clinical differentials with overlapping clinical, pathological, and imaging features is difficult to diagnose and treat, as it often presents late after significant neuronal damage has already occurred. Novel disease-modifying treatments being developed will have to be corroborated with innovative imaging biomarkers so that earlier reliable diagnosis can be made and treatment initiated upon. Along with new specific PET radiotracers, integrated PET/MRI with combined methodological advantage and simultaneously acquired structural-cum-functional information may help achieve this goal. The present pictorial essay details our experiences with PET/MRI in dementing disorders, along with reviewing recent advances and future scope

The aim of our study was to evaluate the value of a pictorial atlas of 123 I FP-CIT SPECT images for aid in the visual diagnosis. Patients, materials, methods: Sixty patients, of whom 20 were clinically diagnosed as 'non-parkinsonian' and 40 as having Parkinson's disease or any related disorder, were included in the study. An atlas consisting of 12 123 I FP-CIT SPECT images was constructed first. Validity of the atlas was investigated by performing a receiver operating characteristic (ROC) analysis with the clinical diagnosis as the gold standard. The remaining 48 SPECT images were visually assessed twice by 5 observers, first with and secondly without consulting the atlas, or vice versa. The added value of the atlas was investigated by comparing the diagnostic accuracy and the interobserver variability for both methods. Results: ROC analysis performed on the atlas yielded an area under the curve of 1 for a threshold discriminating between clinically non-parkinsonian and parkinsonian patients that was situated between image 4 and 5 of the atlas, For the diagnostic accuracy, we found that the area under the ROC curve was systematically higher if observers had access to the atlas compared to when they had not (Wilcoxon's test, p 123 I FP-CIT SPECT scans.

We present new astrometry for the young (12-21 Myr) exoplanet β Pictoris b taken with the Gemini/NICI and Magellan/MagAO instruments between 2009 and 2012. The high dynamic range of our observations allows us to measure the relative position of β Pic b with respect to its primary star with greater accuracy than previous observations. Based on a Markov Chain Monte Carlo analysis, we find the planet has an orbital semi-major axis of 9.1{sub −0.5}{sup +5.3} AU and orbital eccentricity <0.15 at 68% confidence (with 95% confidence intervals of 8.2-48 AU and 0.00-0.82 for semi-major axis and eccentricity, respectively, due to a long narrow degenerate tail between the two). We find that the planet has reached its maximum projected elongation, enabling higher precision determination of the orbital parameters than previously possible, and that the planet's projected separation is currently decreasing. With unsaturated data of the entire β Pic system (primary star, planet, and disk) obtained thanks to NICI's semi-transparent focal plane mask, we are able to tightly constrain the relative orientation of the circumstellar components. We find the orbital plane of the planet lies between the inner and outer disks: the position angle (P.A.) of nodes for the planet's orbit (211.8 ± 0.°3) is 7.4σ greater than the P.A. of the spine of the outer disk and 3.2σ less than the warped inner disk P.A., indicating the disk is not collisionally relaxed. Finally, for the first time we are able to dynamically constrain the mass of the primary star β Pic to 1.76{sub −0.17}{sup +0.18} M {sub ☉}.

Objective: This pictorial review analyzes the magnetic resonance (MR) fascial/muscular changes in 69 patients referred as emergencies with acute swelling of the limbs (ASL) from various causes. Methods and material: A prospective MR imaging (MRI) study of 69 patients referred as emergencies for ASL was performed. Our population consisted of 45 patients with skin and soft-tissue infections (cellulitis and necrotizing fasciitis, and pyomyositis), six patients with soft-tissue inflammatory diseases (dermatomyositis, graft-versus-host disease), 11 patients with acute deep venous thrombosis, three patients with rhabdomyolysis, one patient with acute denervation and three other patients with rare diseases. Hematomas, tumorous or infectious bone involvement and soft-tissue tumors were excluded. All studies included spin echo T1-weighted images and spin echo T2-weighted images. Gadolinium-enhanced spin echo T1-weighted images were obtained when an abscess was suspected on T2-weighted images. Selective fat-saturated T1- and T2-weighted sequences were also used. MRI analysis was performed to obtain a compartmentalized anatomical approach according to the location of signal abnormalities in subcutaneous fat, superficial and deep fascia and muscle. Results: In all patients with ASL, MRI demonstrated soft-tissue abnormalities involving subcutaneous fat, superficial fascia, deep fascia, or muscle. Although MR findings were non-specific, MRI appears sensitive for detecting subtle fascial and muscle signal changes. Conclusions: In skin and soft-tissue infections, MRI can be helpful for therapeutic management by determining the depth of soft-tissue involvement, particularly within fasciae and muscles, which is partly related to the severity of cellulitis with severe systemic manifestations. MRI can also aid the surgeon in diagnosing abscesses. In inflammatory diseases, MRI can determine the best site for biopsy and also monitor therapeutic response.

Public health benefits from pictorial health warnings on US cigarette packs: a SimSmoke simulation.

While many countries have adopted prominent pictorial warning labels (PWLs) for cigarette packs, the USA still requires only small, text-only labels located on one side of the cigarette pack that have little effect on smoking-related outcomes. Tobacco industry litigation blocked implementation of a 2011 Food and Drug Administration's (FDA) rule requiring large PWLs. To inform FDA action on PWLs, this study provides research-based estimates of their public health impacts. Literature was reviewed to identify the impact of cigarette PWLs on smoking prevalence, cessation and initiation. Based on this analysis, the SimSmoke model was used to estimate the effect of requiring PWLs in the USA on smoking prevalence and, using standard attribution methods, on smoking-attributable deaths (SADs) and key maternal and child health outcomes. Available research consistently shows a direct association between PWLs and increased cessation and reduced smoking initiation and prevalence. The SimSmoke model projects that PWLs would reduce smoking prevalence by 5% (2.5%-9%) relative to the status quo over the short term and by 10% (4%-19%) over the long term. Over the next 50 years, PWLs are projected to avert 652 800 (327 000-1 190 500) SADs, 46 600 (17 500-92 300) low-birth-weight cases, 73 600 (27 800-145 100) preterm births and 1000 (400-2000) cases of sudden infant death syndrome. Requiring PWLs on all US cigarette packs would be appropriate for the protection of the public health, because it would substantially reduce smoking prevalence and thereby reduce SADs and the morbidity and medical costs associated with adverse smoking-attributable birth outcomes.

This investigation is based on the study of the pictorial technique employed in a wall painting from El Padre coffee plantation situation in Madruga, Havana, and built at beginning of XIX century. The knowledge about pictorical techniques that was used in a painting is a typical research in Archaeometry, because it is so important the art historical information as scientific results to conclude about the real materials and procedures that were used in the past by the artists . The prediction of a wall painting pictorical technique is carrying out trough the knowledge of pigments, mortars layers and binding substance composition. The non destructive inorganic microanalysis of mortars layers and pigments was determined by a portable XRF system, which is very useful because of the most of pigments are of inorganic nature. A pinpoint samples microanalysis of each color from the painting were done by complementary and traditional technique in stratigraphic studies such as: optical microscopy, micro- chemical drop test, Scanning Electron Microscopy with Energy Dispersive X-Ray attachment (SEM-EDX), gas chromatography and Fourier Transformed Infra Red Spectroscopy (FTIR). The overlapping of layers was obtained by optical microscopy, The mortars composition was investigated by micro-chemical drop test and SEM/EDX and further confirmed by FTIR. The presence of binding substances in colors layers was identified by specific staining test and Gas Chromatography

Uterine leiomyomas (fibroids), the most common benign tumor in women of childbearing age, can cause symptoms including dysmenorrhea, menorrhagia, urinary symptoms, pain and infertility. Hysterectomy is a common approach to treating uterine fibroids, and less invasive surgical approaches such as myomectomy and uterine artery embolization also have been shown to alleviate symptoms. Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is the only totally non-invasive surgical approved method for treating uterine fibroids. In clinical trials, MRgFUS resulted in significant relief of uterine fibroid symptoms. The safe and effective use of MRgFUS is affected by fibroid type and location, position relative to adjacent anatomical structures and the presence of co-existent pelvic disease. Additionally, successful outcomes with MRgFUS have been correlated with the volume of fibroids ablated during the procedure. Thus, selection of patients in whom sufficient fibroid volumes can be treated safely using the MRgFUS system is critical for successful outcomes. The MR images in this pictorial essay provide examples of uterine fibroids for which MRgFUS should be considered and is designed to facilitate the selection of patients for whom MRgFUS is most likely to provide sustained symptom relief.

To validate the PRISM (Pictorial Representation of Illness and Self Measure) tool, a novel visual instrument, for the assessment of health-related quality of life in dermatological inpatients compared with the Dermatology Life Quality Index (DLQI) and the Skindex-29 questionnaires and to report qualitative information on PRISM. In an open longitudinal study, PRISM and Skindex-29 and DLQI questionnaires were completed and HRQOL measurements compared. Academic dermatological inpatient ward. The study population comprised 227 sequential dermatological inpatients on admission. Patients completed the PRISM tool and the Skindex-29 and DLQI questionnaires at admission and discharge. PRISM Self-Illness Separation (SIS) score; Skindex-29 and DLQI scores; and qualitative PRISM information by Mayring inductive qualitative context analysis. The PRISM scores correlated well with those from the Skindex-29 (rho = 0.426; P quality of life questionnaires to assess changes in the burden of suffering during hospitalization. Inductive qualitative context analysis revealed impairment of adjustment and self-image as major aspects. Patients overall expected symptomatic and functional improvement. In patients with psoriasis and leg ulcers, many expected no treatment benefit. The PRISM tool proved to be convenient and reliable for health-related quality of life assessment, applicable for a wide range of skin diseases, and correlated with DLQI and Skindex-29 scores. With the PRISM tool, free-text answers allow for the assessment of individual information and potentially customized therapeutic approaches.

Full Text Available Abstract Background Pictorial warning labels (PWLs deter initiation and motivate quitting. Assessing PWLs is important to track effectiveness and wear out. Jordan introduced an updated set of PWLs in 2013. This study assessed the effectiveness of the set after 2.5 years on the market. Methods We administered a survey in a cross-sectional sample of young adults aged 17–26 years. For convenience, respondents were recruited on university campuses. For heterogeneity, respondents were solicited from the different schools in four geographically diverse university campuses. The study compared perceptions of effectiveness surveyed in 2015 to perceptions gauged in 2010 during a pre-launch evaluation exercise. Outcomes of interest were: salience, fear evocation, adding information, and ability to motivate quitting smoking (for smokers or deterring starting (for non-smokers. Results Results indicate awareness of the set among smokers and non-smokers, and their recall of at least one PWL message. Results also indicate effectiveness of the set: (1 1/3 smokers who frequently saw them reported PWLs to trigger considering quitting, (2 and among both smokers and non-smokers the set in 2015 sustained ability to motivate quitting and staying smoke-free. However, results uncover erosion of salience, suggesting that the set has reached its end of life. Finally, results reveal variability in performance among PWLs; the one PWL that depicts human suffering significantly outperformed the others, and its ability to motivate was most strongly associated with its ability to evoke fear. Conclusion Based on the early signs of wear-out (i.e. erosion of salience, and understanding the importance of sustaining upstream outcomes (especially fear evocation to sustain motivation, we recommend retiring this set of PWLs and replacing it with a stronger set in line with proven standards.

Full Text Available Although nutritional screening and dietary monitoring in clinical settings are important, studies on related user satisfaction and cost benefit are still lacking. This study aimed to: (1 elucidate the cost of implementing a newly developed dietary monitoring tool, the Pictorial Dietary Assessment Tool (PDAT; and (2 investigate the accuracy of estimation and satisfaction of healthcare staff after the use of the PDAT. A cross-over intervention study was conducted among 132 hospitalized patients with diabetes. Cost and time for the implementation of PDAT in comparison to modified Comstock was estimated using the activity-based costing approach. Accuracy was expressed as the percentages of energy and protein obtained by both methods, which were within 15% and 30%, respectively, of those obtained by the food weighing. Satisfaction of healthcare staff was measured using a standardized questionnaire. Time to complete the food intake recording of patients using PDAT (2.31 ± 0.70 min was shorter than when modified Comstock (3.53 ± 1.27 min was used (p < 0.001. Overall cost per patient was slightly higher for PDAT (United States Dollar 0.27 ± 0.02 than for modified Comstock (USD 0.26 ± 0.04 (p < 0.05. The accuracy of energy intake estimated by modified Comstock was 10% lower than that of PDAT. There was poorer accuracy of protein intake estimated by modified Comstock (<40% compared to that estimated by the PDAT (>71% (p < 0.05. Mean user satisfaction of healthcare staff was significantly higher for PDAT than that for modified Comstock (p < 0.05. PDAT requires a shorter time to be completed and was rated better than modified Comstock.

The Pictorial Representation of Self and Illness Measure (PRISM) measures in a simple, graphic way the burden of suffering due to illness. The question addressed in this study is whether the PRISM is a valid instrument to measure suffering in cancer survivors experiencing severe fatigue. Quantitative and qualitative data of a previous randomized controlled trial demonstrating the efficacy of cognitive behavior therapy (CBT) especially designed for postcancer fatigue was used to assess convergent validity and sensitivity to change in a sample of 83 cancer survivors. The PRISM, yielding self-illness separation (SIS-fatigue = suffering due to fatigue; SIS-cancer = suffering due to cancer), fatigue severity (Checklist Individual Strength; CIS-fatigue), functional impairment, psychological well-being, quality of life, and coping with the experience of cancer (Impact of Event Scale; IES). Moderate significant correlations were found with the PRISM and the above-mentioned measures. On the basis of SIS scores, the sample was divided into two separate groups: cancer survivors who suffered more because of fatigue and cancer survivors who suffered more because they had cancer in the past. The two groups had different scores on CIS-fatigue and IES, in line with that aspect that caused them the most suffering. The qualitative data confirmed this finding. Participants in the CBT condition demonstrated a significant difference between SIS-fatigue at baseline versus 6 months later compared with those in the waiting list condition. No change of SIS-cancer was found. The PRISM seems to be a valuable tool in fatigue research and clinical practice. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Plesznivy, Edit

2015-01-01

The study presents the emancipation of the artworks of psychiatric patients through the review of four centuries, focusing on some of the most important medical cultural and art historical stages of the period between the 18th and the 21st century, which is a particularly relevant era in this regard. It touches on the collections linked to psychiatrists and hospitals that were formed primarily on the basis of the researches that were analyzing the connection between creativity and mental illness. After that, the study discusses the ever-changing attitudes and preferences of artists' and major artistic movements towards psychosis and the pictorial world of the psychotic. With great care, it analyses the aesthetic category of the art brut, which is connected to the French painter Jean Dubuffet and was born in the middle of the 1940s, and the relationship between contemporary art and art brut. In connection with some of the most significant art brut collections and exhibitions, the works of a few classical and contemporary art brut artists are also discussed (Adolf Wolfli, Louis Soutter, Aloise Corbaz, August Walla ).

2015-12-01

A new free-living marine nematode species Hopperia sinensis sp. nov. from mangrove forests of Fujian Province, China, is identified and illustrated. Hopperia sinensis sp. nov. is characterized by its cephalic setae 2.4-2.8 µm long or 17%-20% head diameter, and amphids of 2.25-2.5 turns. Lateral differentiation appears with larger, more irregularly distributed dots behind 3-5 transverse rows of dots posterior to amphid. Buccal cavity is consisted of a shallow and weakly sclerotized cup-shaped portion with strongly sclerotized walls of 18-21 µm deep. There are three sclerotized and size-equally pointed teeth at the junction between the two parts. Spicules of 41-45 µm long are slightly curved with broadband velum and central strips at the proximal end. The gubernacula, with apparent lateral guiding pieces, are formed by one central tubular piece that is weakly sclerotized with 11-16 µm long dorso-caudally directed apophyses. There are 13-14 fine tubular precloacal supplements. Conico-cylindrical tail gradually tapers till pointed tail tip. Female is similar to male, but have a longer body and tail. Ovaries are opposed and outstretched, with anterior ovary to the left and posterior ovary to the right of the intestine. A pictorial key to all the valid known species in genus Hopperia is given.

Technique, Thematic, Symbolism and Semiotics - Authentic Synthesis in Adem Kastrati’s Creativity

Directory of Open Access Journals (Sweden)

Shpresa Tolaj-Gjonbalaj

2015-03-01

Full Text Available The choice to bring this topic consists in choosing the creative vocation of the inventive painter Adem Kastrati, who articulates the artistic work with a unique technique, the usage of brown soil color, as a pictorial material and tool without artificial mixture, stressing also the application of the specific pictorial structure, which is considered unique up to now. Main objective of this paper is the analysis of the technical, thematic, symbolic and semiotic authenticity, in Adem Kastrati’s works, which is based on the Albanian traditional history. The artist’s tendency to create a form of art apprehensible to all, through the articulation of a clear figurative language which occupies a specific considered space in the paper, shows the artist’s message transmission to receptive level in reference to psychological-spiritual condition. This paper is based on primary and secondary sources, direct analysis of the artist’s activity, as well as different materials and publishing. As for the idea, technique, theme, variety of signs and symbols reflected, it is important to notice that the artist’ s skill is very original in the universe of inventive values of pictorial art that is why he occupies an important position in the Albanian culture. Consequently, this paper reflects a unique panorama of the authentic synthesis of specifications that characterize this artist’s activity. Therefore through this exposition, we are trying not only to highlight his creativity, but we are also trying to highlight his works to all the competent institutions nationwide, whose art was presented in 50 individual and collective exhibitions in different countries of the world.

Heavy menstrual bleeding is a common symptom reported by approximately 30% of women. The Pictorial Blood Assessment Chart (PBAC) score is often used to quantify severity of menstrual bleeding. However, the traditional PBAC paper diary might be subject to recall bias and compliance issues, especially in adolescents. We developed a mobile application (app) version of the PBAC score and evaluated patient satisfaction and compliance with app reporting vs paper reporting. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This study was a randomized cross-over study of 25 postmenarchal female adolescents and young women ages 13-21 years. Participants agreed to track bleeding in 2 consecutive menstrual cycles and were randomized to use the PBAC paper diary or mobile app format first. At the end of each cycle, a satisfaction survey and system usability scale (app only) was used to assess the acceptability of the format used. Twenty-five participants had a median age of 15 years. Cross-over analysis showed that satisfaction level was significantly higher for the app (P < .001). Twenty of 25 (80%) participants preferred the app over the paper diary. For the app, 20 of 25 participants (80%) had high compliance for reporting bleeding, with a mean of 2 app entries per day. Participants' PBAC scores did not vary significantly between the paper diary (median, 95) and mobile app (median, 114). All paper diaries met definition for high compliance. There was no significant period or carryover effect. This study showed that a PBAC app compared with the paper diary was the preferred method of recording menstrual bleeding in adolescents and showed feasibility as a research data collection tool.

We analyze new/archival VLT/NaCo and Gemini/NICI high-contrast imaging of the young, self-luminous planet β Pictoris b in seven near-to-mid IR photometric filters, using advanced image processing methods to achieve high signal-to-noise, high precision measurements. While β Pic b's near-IR colors mimic those of a standard, cloudy early-to-mid L dwarf, it is overluminous in the mid-infrared compared to the field L/T dwarf sequence. Few substellar/planet-mass objects—i.e., κ And b and 1RXJ 1609B—match β Pic b's JHK s L' photometry and its 3.1 μm and 5 μm photometry are particularly difficult to reproduce. Atmosphere models adopting cloud prescriptions and large (∼60 μm) dust grains fail to reproduce the β Pic b spectrum. However, models incorporating thick clouds similar to those found for HR 8799 bcde, but also with small (a few microns) modal particle sizes, yield fits consistent with the data within the uncertainties. Assuming solar abundance models, thick clouds, and small dust particles ((a) = 4 μm), we derive atmosphere parameters of log (g) = 3.8 ± 0.2 and T eff = 1575-1650 K, an inferred mass of 7 +4 -3 M J , and a luminosity of log(L/L ☉ ) ∼–3.80 ± 0.02. The best-estimated planet radius, ≈1.65 ± 0.06 R J , is near the upper end of allowable planet radii for hot-start models given the host star's age and likely reflects challenges constructing accurate atmospheric models. Alternatively, these radii are comfortably consistent with hot-start model predictions if β Pic b is younger than ≈7 Myr, consistent with a late formation well after its host star's birth ∼12 +8 -4 Myr ago

[Artistic dream reconstructions of the Wolf Man in the light of experimental findings].

Science.gov (United States)

Leuschner, W; Hau, S

1995-07-01

The authors take the famous dream picture by the "wolf-man" as the starting-point for experimental research of their own and relate the one to the other. They see the significance of pictorial representations of dreams less in the supplementary information they convey about the "text" of dreams than in the fact that they give separate expression to motility-based "gesture-associated" memories and ideas. These need to be distinguished from "language-associated" memories as there are dissociated modes of encoding experience underlying verbal and pictorial representation. The splitting of these modes into different part-codes is an important component of repression. In addition, the pictorial representation of dreams enables the patient to re-associate part-codes and thus achieve a "deferred" reconstruction and complementation of significant experiences. In the authors view, pictorial representation is favorable to the discovery of repressed material; it is as yet however impossible to say exactly what relationship there is between verbalized and pictorial representation in the context of analysis.

Population-level interventions can possibly enhance each other's effects when they are implemented simultaneously. When the plain packaging policy was implemented in Australia, pictorial health warning labels (HWLs) on cigarette packages were also updated and a national mass media campaign was aired. This study examined whether smokers who recalled the media campaign reported more attention to and talking about HWLs. Longitudinal survey data was obtained among Australian adult smokers, aged 18 years and older, from an online consumer panel. One survey wave was conducted before (September 2012) and two waves were conducted after (January 2013 and May 2013) the interventions. The sample was replenished to maintain a sample size of 1000 participants at each wave. Generalized Estimating Equations analyses were performed. Compared to wave 1, attention to HWLs increased at wave 2 (b=0.32, SE=0.06, pCampaign recall was significantly associated with more attention to HWLs (b=0.29, SE=0.05, pcampaign was associated with more attention to and talking about HWLs. When adjusting for campaign recall, there was still an increasing trend in attention and talking. This suggests that the media campaign and the new packaging and labeling policies had independent and positive effects on attention to and talking about HWLs. Copyright © 2015 Elsevier Ltd.

Bonifazi, Giuseppe; Gargiulo, Aldo; Serranti, Silvia; Raspi, Costantino

2007-02-01

Ornamental stone products are commercially classified on the market according to several factors related both to intrinsic lythologic characteristics and to their visible pictorial attributes. Sometimes these latter aspects prevail in quality criteria definition and assessment. Pictorial attributes are in any case also influenced by the performed working actions and the utilized tools selected to realize the final stone manufactured product. Stone surface finishing is a critical task because it can contribute to enhance certain aesthetic features of the stone itself. The study was addressed to develop an innovative set of methodologies and techniques able to quantify the aesthetic quality level of stone products taking into account both the physical and the aesthetical characteristics of the stones. In particular, the degree of polishing of the stone surfaces and the presence of defects have been evaluated, applying digital image processing strategies. Morphological and color parameters have been extracted developing specific software architectures. Results showed as the proposed approaches allow to quantify the degree of polishing and to identify surface defects related to the intrinsic characteristics of the stone and/or the performed working actions.

On so-called paradoxical monocular stereoscopy.

Human observers are apparently well able to judge properties of 'three-dimensional objects' on the basis of flat pictures such as photographs of physical objects. They obtain this 'pictorial relief' without much conscious effort and with little interference from the (flat) picture surface. Methods for 'magnifying' pictorial relief from single pictures include viewing instructions as well as a variety of monocular and binocular 'viewboxes'. Such devices are reputed to yield highly increased pictorial depth, though no methodologies for the objective verification of such claims exist. A binocular viewbox has been reconstructed and pictorial relief under monocular, 'synoptic', and natural binocular viewing is described. The results corroborate and go beyond early introspective reports and turn out to pose intriguing problems for modern research.

Non destructive testing of works of art by terahertz analysis

Improvements in technologies and the growing security needs in airport terminals lead to the development of non destructive testing devices using terahertz waves. Indeed, these waves have the advantage of being, on one hand, relatively penetrating. They also have the asset of not being ionizing. It is thus potentially an interesting contribution in the non destructive testing field. With the help of the VISIOM Company, the possibilities of this new industrial analysis method in assisting the restoration of works of art were then approached. The results obtained within this framework are presented here and compared with those obtained by infrared thermography. The results obtained show first that the THZ method, like the stimulated infrared thermography allows the detection of delamination located in murals paintings or in marquetries. They show then that the THZ method seems to allow detecting defects located relatively deeply (10 mm) and defects potentially concealed by other defects. It is an advantage compared to the stimulated infra-red thermography which does not make it possible to obtain these results. Furthermore, they show that the method does not seem sensitive to the various pigments constituting the pictorial layer, to the presence of a layer of "Japan paper" and to the presence of a layer of whitewash. It is not the case of the stimulated infrared thermography. It is another advantage of the THZ method. Finally, they show that the THZ method is limited in the detection of low-size defects. It is a disadvantage compared to the stimulated infrared thermography.

Popova, Lucy; Owusu, Daniel; Jenson, Desmond; Neilands, Torsten B

2017-04-20

In reviewing the first set of pictorial warning labels in the USA, the courts equated textual labels with facts and information, and images with emotion. This study tested the differences in perceived informativeness and emotion between textual and pictorial cigarette warning labels. An online study with 1838 US adults who were non-smokers (n=764), transitioning smokers (quit smoking in the past 2 years or currently trying to quit, n=505) or current smokers (n=569). Each participant evaluated 9 out of 81 text and pictorial cigarette warning labels. Participants reported to what extent they perceived the label as informative and factual and the negative emotions they felt while looking at each label. We used linear mixed models to account for the nesting of multiple observations within each participant. There were no significant differences in perceived informativeness between textual (mean 6.15 on a 9-point scale) and pictorial labels (6.14, p=0.80, Cohen's d=0.003). Textual labels evoked slightly less emotion (4.21 on a 9-point scale) than pictorial labels (4.42, pemotion were strongly correlated (Pearson r=0.53, pemotional and not factual. Pictorial labels are rated as informative and factual, textual labels evoke emotion, and emotionality and informativeness are strongly correlated. These findings serve as evidence for the Food and Drug Administration (FDA) to counteract the claim that pictorial warning labels, by definition, are not 'purely factual and uncontroversial'. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Context. Low-mass members of young loose stellar associations and open clusters exhibit a wide spread of rotation periods. Such a spread originates from the distributions of masses and initial rotation periods. However, multiplicity can also play a significant role. Aims: We aim to investigate the role played by physical companions in multiple systems in shortening the primordial disk lifetime, anticipating the rotation spin up with respect to single stars. Methods: We have compiled the most extensive list to date of low-mass bona fide and candidate members of the young 25-Myr β Pictoris association. We have measured from our own photometric time series or from archival time series the rotation periods of almost all members. In a few cases the rotation periods were retrieved from the literature. We used updated UVWXYZ components to assess the membership of the whole stellar sample. Thanks to the known basic properties of most members we built the rotation period distribution distinguishing between bona fide members and candidate members and according to their multiplicity status. Results: We find that single stars and components of multiple systems in wide orbits (>80 AU) have rotation periods that exhibit a well defined sequence arising from mass distribution with some level of spread likely arising from initial rotation period distribution. All components of multiple systems in close orbits (Pleiades shows that whereas the evolution of F-G stars is well reproduced by angular momentum evolution models, this is not the case for the slow K and early-M stars. Finally, we find that the amplitude of their light curves is correlated neither with rotation nor with mass. Conclusions: Once single stars and wide components of multiple systems are separated from close components of multiple systems, the rotation period distributions exhibit a well defined dependence on mass that allows us to make a meaningful comparison with similar distributions of either younger or older

Metaphor in pictures.

Science.gov (United States)

Kennedy, J M

1982-01-01

Pictures can be literal or metaphoric. Metaphoric pictures involve intended violations of standard modes of depiction that are universally recognizable. The types of metaphoric pictures correspond to major groups of verbal metaphors, with the addition of a class of pictorial runes. Often the correspondence between verbal and pictorial metaphors depends on individual features of objects and such physical parameters as change of scale. A more sophisticated analysis is required for some pictorial metaphors, involving juxtapositions of well-known objects and indirect reference.

Impact of tobacco-related health warning labels across socioeconomic, race and ethnic groups: results from a randomized web-based experiment.

Directory of Open Access Journals (Sweden)

Jennifer Cantrell

Full Text Available BACKGROUND: The U.S. Family Smoking Prevention and Tobacco Control Act of 2009 requires updating of the existing text-only health warning labels on tobacco packaging with nine new warning statements accompanied by pictorial images. Survey and experimental research in the U.S. and other countries supports the effectiveness of pictorial health warning labels compared with text-only warnings for informing smokers about the risks of smoking and encouraging cessation. Yet very little research has examined differences in reactions to warning labels by race/ethnicity, education or income despite evidence that population subgroups may differ in their ability to process health information. The purpose of the present study was to evaluate the potential impact of pictorial warning labels compared with text-only labels among U.S. adult smokers from diverse racial/ethnic and socioeconomic subgroups. METHODS/FINDINGS: Participants were adult smokers recruited from two online research panels (n = 3,371 into a web-based experimental study to view either the new pictorial warnings or text-only warnings. Participants viewed the labels and reported their reactions. Adjusted regression models demonstrated significantly stronger reactions for the pictorial condition for each outcome salience (b = 0.62, p<.001; perceived impact (b = 0.44, p<.001; credibility (OR = 1.41, 95% CI = 1.22-1.62, and intention to quit (OR = 1.30, 95% CI = 1.10-1.53. No significant results were found for interactions between condition and race/ethnicity, education, or income. The only exception concerned the intention to quit outcome, where the condition-by-education interaction was nearly significant (p = 0.057. CONCLUSIONS: Findings suggest that the greater impact of the pictorial warning label compared to the text-only warning is consistent across diverse racial/ethnic and socioeconomic populations. Given their great reach, pictorial health warning labels may be one of the few tobacco

Assuming solar abundance models, thick clouds, and small dust particles ((a) = 4 μm), we derive atmosphere parameters of log (g) = 3.8 ± 0.2 and T{sub eff} = 1575-1650 K, an inferred mass of 7{sup +4}{sub -3} M{sub J} , and a luminosity of log(L/L{sub ☉}) ∼–3.80 ± 0.02. The best-estimated planet radius, ≈1.65 ± 0.06 R{sub J} , is near the upper end of allowable planet radii for hot-start models given the host star's age and likely reflects challenges constructing accurate atmospheric models. Alternatively, these radii are comfortably consistent with hot-start model predictions if β Pic b is younger than ≈7 Myr, consistent with a late formation well after its host star's birth ∼12{sup +8}{sub -4} Myr ago.

This study evaluated the relationship between interpersonal communication about cigarette health warning labels (HWLs), psychological responses to HWLs, and smoking cessation attempts. Data were analyzed from online consumer panels of adult smokers in Australia, Canada and Mexico, during implementation of new pictorial health warning labels (HWLs) on cigarette packs. Approximately 1000 adult smokers were surveyed in each country every four months (September 2012, January 2013, May 2013, September 2013, January 2014). Only smokers followed for at least two waves were included in the analytic sample. Participants reported the frequency of talking about HWLs in the last month (in general, with family members, and with friends). For each country, poisson generalized estimating equation (GEE) models were estimated to assess the bivariate and adjusted correlates of talking about HWLs. Logistic GEE models regressed having attempted to quit by the subsequent wave on HWL talk, sociodemographics and psychological responses to HWLs. The frequency of HWL talk gradually decreased in Canada (48%-36%) after new HWLs were implemented; an increase (30%-58%) in Australia corresponded with implementation of new HWLs, after which talking stabilized; and the frequency of HWL talk in Mexico was stable over time, where new HWLs are implemented every six months. Talk about HWLs was an independent predictor of subsequent quit attempts in Canada (AOR = 1.50; 95% CI = 1.11-2.02), Australia (AOR = 1.41; 95% CI = 1.05-1.89), and Mexico (AOR = 1.53; 95% CI = 1.11-2.10), as was cognitive responses to HWLs (Australia AOR = 1.66; 95% CI = 1.22-2.24; Canada AOR = 1.56; 95% CI = 1.15-2.11; Mexico AOR = 1.30; 95% CI = 0.91-1.85). No interaction between talk and cognitive reactions to HWLs were found. These results suggest that interpersonal communication about HWLs influences smoking cessation attempts independent of other established predictors of smoking cessation, including

Pictorial health warning labels on cigarette packaging have been proposed for the U.S., but their potential influences among populations that suffer tobacco-related health disparities are unknown. To evaluate pictorial health warning labels, including moderation of their influences by health literacy and race. From July 2011 to January 2012, field experiments were conducted with 981 adult smokers who were randomized to control (i.e., text-only labels, n=207) and experimental conditions (i.e., pictorial labels, n=774). The experimental condition systematically varied health warning label stimuli by health topic and image type. Linear mixed effects (LME) models estimated the influence of health warning label characteristics and participant characteristics on label ratings. Data were analyzed from January 2012 to April 2012. Compared to text-only warning labels, pictorial warning labels were rated as more personally relevant (5.7 vs 6.8, pinteractions indicated that labels with graphic imagery produced minimal differences in ratings across racial groups and levels of health literacy, whereas other imagery produced greater group differences. Pictorial health warning labels with graphic images have the most-pronounced short-term impacts on adult smokers, including smokers from groups that have in the past been hard to reach.

The resonant modes in the 9-cell 3.9 GHz bunch shaping cavity designed by FERMILAB in collaboration with DESY and installed in FLASH at DESY were calculated up to the range of 10 GHz in terms of the band structure of this design. The modal nature of this structure has previously been investigated by various parties. We have extended this work to include a modal pictorial dictionary in which the nature of the modes can be readily identified as well as the R/Q's for each of the modes. Below 10 GHz only monopole, dipole, quadrupole and sextupole bands exist for this particular structure. Herein we only consider the modal patterns of the bands themselves and have not included the beampipe modes in the pictorial dictionary. In addition to the finite element simulations we also utilise a capacitive-inductive circuit model to achieve a rapid characterisation of the cavity. (orig.)

Il Cabinet d'amateur di Georges Perec

Full Text Available In 1979 one year after the publication of La vie mode d’emploi, George Perec wrote Cabinet d’amateur. Histoire d’un tableau, in which he tells the story of a painting belonging to the genre of the cabinet d’amateur, also known as kunst- und wunderkammer. It is a collection of different paintings, usually belonging to a rich man or a notable, portrayed (once again in a single picture celebrating the magnificence of this more or less real collection. As for the pictorial genre, so the short novel is the celebration of the images collected by George Perec in his previous masterpiece, La vie mode d’emploi. This is why I assume this work to be referable to the genre of structural homology more than to that of ékphrasis, being the pictorial structure not only the thematic inspiration or motif of the novel but its own underlying structure

A detailed analysis in the iconography and pictorial appearance of the scene of the "Prophet Jonah" painted by the artist Michelangelo Buonarroti (1475-1564) on the ceiling of the Sistine Chapel between the years 1508 and 1512. Literature review on the Italian Renaissance period and the life of Michelangelo Buonarroti and analysis of historical aspects of the evolution of studies of human anatomy in this period and the works of the artist. A comparative analysis of the representation of the figure of the fish on the left thigh of "Jonah " with a cross section of penis shows a curious similarity. The pictorial and iconographic analysis reveals an intensity of light on the pubic area and the position of the prophet with the legs spread apart and left hand placed on this region. A tube-shaped cloth covers the region and the angel at the side seems to be looking at this anatomical region of "Jonah". In fact, sets of iconographic and pictorial relate to the deciphered code. This description helps to confirm the relationship of the Renaissance art with the human anatomy; science has been much studied in this period. The design of a cross section of the penis is revealed with the two cavernous bodies with the septum between them and the spongy body. Considering the circumstances in which Michelangelo had painted, subjectivity was fundamental due to religious motivations added to the vigorous implications of a limited scientific knowledge typical of that era.

Properties of the binding mechanism in associative recognition were studied by examining the influence of the pictorial superiority effect on the age-related associative deficit. The informative aspect of associative recognition is the recollection of the pairing. Previous findings indicate that recollection is susceptible to aging and that pictorial presentation can enhance recollection and facilitate associative recognition. Pictorial presentation was found to facilitate item recognition by both young and older adults, associative recognition by young adults, but not associative recognition by older adults. Our findings support the hypothesis that the binding mechanism in associative recognition is content independent. Theoretical implications are discussed. (c) 2016 APA, all rights reserved).

Without Pictorial Detour: Benjamin, Mies and the Architectural Image

Directory of Open Access Journals (Sweden)

Lutz Robbers

2016-05-01

Full Text Available It can be argued that architectural knowledge was of crucial importance to Walter Benjamin for elaborating his version of an anthropological historical materialism. Between 1929 and 1931 he encounters two publications on architectural history which had a decisive impact on his ensuing works: Sigfried Giedion’s Bauen in Frankreich, Bauen in Eisen, Bauen in Eisenbeton (1928 and Carl Linfert’s Die Grundlagen der Architekturzeichnung (1931. It can be argued that both works played a role in affirming, if not developing his historical method of awakening the dreaming collective into a ‘now of recognisability,’ a method which one can argue is based on a specific image-based epistemology. Especially the architectural image, whether in the form of a printed drawing, photographic illustration, or an actual built object, appears to have been crucial for placing the history of media technologies (architecture being one of these media in a constellation with the ‘archaic symbol-worlds of mythologies.’ If architecture is, as Benjamin claims in his initial notes for The Arcades Project, ‘the most important testimony to latent “mythology,”’ the architectural image might very well be the agent that causes the moment of awakening, the instance when a constellation between technology and ancient symbol worlds is formed. In the second part of this essay, I will attempt to elaborate such a designation for the specificity of the architectural image by analysing a number of Ludwig Mies van der Rohe’s drawings and collages from the 1920s as architectural images in the Benjaminian sense.

Study of the inner part of the β pictoris dust disk: deconvolution of 10 microns images and modelization of the dust emission

International Nuclear Information System (INIS)

Pantin, Eric

1996-01-01

In 1984, the observations of the infrared satellite IRAS showed that numerous main-sequence stars are surrounded by a relatively tenuous dust disk. The most studied example is the disk of the star Beta Pictoris. The corono-graphic observations are limited to the most outer regions of the disk. In infrared, it is not the case. We have used an infrared camera to obtain 10 microns images of the central regions. In order to be able to deduce the dust density, one has to fulfil some requirements. First, we had to de-convolute these images degraded by a combination of diffraction and seeing. We initially used standard methods (Richardson-Lucy, Maximum Entropy etc..), then we have developed a new method of astronomical images deconvolution and filtering based on a regularization by Multi-Scales Maximum Entropy. Then we have built a model of thermal emission of the dust to calculate the temperature of the grains. The resulting density shows a region between the star and 50-60 Astronomical Units, depleted of dust. The density is compatible with models simulating the gravitational interactions between such a disk and a planet having a mass the half of Saturn's mass. We have refined the models of the particles' emission: mixture of several materials, porous particles or not, coated with ice or not, to build a global model of the disk taking into account all the observables: IRAS infrared fluxes, 10 and 20 microns fluxes, 10 microns spectrum, scattered fluxes in the visible. In our best model, the particles are porous silicate grains (mixture of olivine and pyroxene) coated with a refractory organics mantle, which becomes 'frozen' (coated with ice) beyond a distance of 90 Astronomical Units from the star. This model allows us to predict an infrared spectrum showing the characteristic emission of the ice around 45-50 microns, that will be compared to the observations of the infrared satellite ISO.

Ackerman, Laurens V.; Burke, M. W.; Rada, Roy

1984-06-01

We have been investigating diagnostic knowledge models which assist in the automatic classification of medical images by combining information extracted from each image with knowledge specific to that class of images. In a more general sense we are trying to integrate verbal and pictorial descriptions of disease via representations of knowledge, study automatic hypothesis generation as related to clinical medicine, evolve new mathematical image measures while integrating them into the total diagnostic process, and investigate ways to augment the knowledge of the physician. Specifically, we have constructed an artificial intelligence knowledge model using the technique of a production system blending pictorial and verbal knowledge about the respective CT scan and patient history. It is an attempt to tie together different sources of knowledge representation, picture feature extraction and hypothesis generation. Our knowledge reasoning and representation system (KRRS) works with data at the conscious reasoning level of the practicing physician while at the visual perceptional level we are building another production system, the picture parameter extractor (PPE). This paper describes KRRS and its relationship to PPE.

2001-01-01

Recently much effort has been dedicated to designing and implementing World Wide Web sites for virtual shopping and e-commerce. Despite this effort, relatively little empirical work has been done to determine the effectiveness with which different site designs sell products. We report three experiments in which participants were asked to search for products in various experimental e-commerce sites. Across the experiments participants were asked to search in either QTVR (QuickTime Virtual Reality), hypertext, or pictorially rich hypertext environments; they were then tested for their ability to recall the products seen and to recognize product locations. The experiments demonstrated that when using QTVR (Experiments 1, 2, and 3) or pictorial environments (Experiment 2), participants retained more information about products that were incidental to their goals. In two of the experiments it was shown that participants navigated more efficiently when using a QTVR environment. The costs and benefits of using 3D virtual environments for on-line shops are discussed. Actual or potential applications of this research include support for the development of e-commerce design guidelines.

2015-12-01

Full Text Available The article deals with pictorial metamorphosis in the opening pages of two early 14th-century manuscripts of the Estoire del saint Graal. Firstly, the episodes depicted are analysed iconographically and formally. Secondly, it explores how pictorial narrative is established in the multi-compartmentalised miniature, that is how the images are linked internally in order to convey a narrative that has its beginning and its ending. Thirdly, it is shown how the images in the opening miniature communicate with other miniatures in the manuscript and how the course of interpretation, signaled by the opening miniature, is succeeded and confirmed by the selection of episodes which are subsequently depicted, as well as by the way in which the episodes depicted are pictorially interpreted.

Seeing is believing: the direct and contingent influence of pictures in health promotion advertising.

Science.gov (United States)

Chang, Chingching

2013-01-01

Because pictures, compared with words, are more effective in triggering vivid imagery, their effects should increase in situations in which they play a crucial role in facilitating imagery. This study accordingly explored the relative effects of information presented in pictorial formats and verbal formats in health promotion advertising. Symptoms presented in pictorial formats increased perceptions of the severity of a disease, whereas prevention options presented in pictorial formats enhanced efficacy in preventing the disease. This study also examined two contingent situations: when people were oriented toward visual processing, and when imagery could not be easily triggered without the help of pictures, such as when symptoms or prevention options were difficult or unpleasant to imagine. The findings of three studies supported the offered predictions.

Full Text Available The theme of this study is pictorial representation of costume and fashion in painting, fashion plates and fashion illustrations. Fashion illustration of the 20th century, specific in terms of freedom of interpretation that is given to the artists when representing fashion trends, has kept those elements of painting that are almost lost in contemporary art movements (for instance figuration. Through several specific examples in art history I will try to demonstrate the artist’s approach to the representation of costume. In this study I will also try to define the role of painting when it comes to the fashion, the role of fashion plates and then the role of fashion illustration created in the early 20th century. Finally, I will take a look at the fashion photography that in the beginning has found its role-models precisely in the fashion illustration and today is returning to the visual characteristics of renaissance art, and to the painting in general, from which everything has begun.

A pattern of cortical functional connectivity in the source space was studied in a group of right-handed adult participants (N = 44:17 women, 27 men, aged M = 29.61 ± 6.45 years) who retained in their working memory (WM) traces of realistic pictures of positive, neutral, and negative emotional valence while in their working memory (WM) while performing same different task in which participants had to compare an etalon picture against a target picture that followed after a specified delay. A coherence (COH) between pairs of cortical sources chosen in advance according to fMRI data was estimated in the theta frequency range for the period of time preceding the etalon stimulus, distinct sets of functional links are found. The links of the first type that presumably reflect the involvement of sustained attention were between the dorsal anterior cingulate cortex, the prefrontal areas, and temporal areas of the right hemispheres. When compared to the rest period, links of this type showed strengthening not only during the retention period but also during the period preceding the etalon picture. The links of the second type presumably reflecting a progressive neocortex-to-hippocampus functional integration with increasing memory load and strengthened exclusively during retention period. Those links were between parietal, temporal and prefrontal cortices in the lateral surface of both hemispheres with the additional inclusion of the posterior cingulate cortex and the medial parietal cortex in the left hemisphere. An impact of emotional valence onto the strength and topography of the functional links of the second type was found. In the left hemisphere, an increase in the strength of cortical interaction was more pronounced for pictures of positive valence than for pictures of either neutral or negative valences. When compared to the pictures of neutral valence, the retention of pictorial information of both positive and negative valence showed some extraneous integration

There is strong evidence showing that pictorial health warnings are more effective than text-only warnings. However, much of this evidence comes from high-income countries and is limited to cigarette packaging. Moreover, few studies have identified mechanisms that might explain the impact of warnings. The current study examined the potential mediating role of negative affect and the moderating influence of message credibility in perceived effectiveness of smokeless tobacco warnings in two low- and middle-income countries (LMICs). Field interviews were conducted in India and Bangladesh, with adult (19+ years) smokeless tobacco users (n=1053), and youth (16-18years) users (n=304) and non-users (n=687). Respondents were randomly assigned to view warnings in one of four conditions: (1) Text-only, (2) pictorial with symbolic imagery, (3) pictorial with graphic images of health effects, or (4) pictorial with personalized graphic images plus a personal testimonial. The findings provide support for the mediating influence of negative affect in perceived effectiveness, for adult and youth smokeless tobacco users who viewed pictorial warnings (vs. text-only), and graphic health warnings (vs. personal testimonials). Among adults, message credibility moderated the indirect effect; the association was stronger when credibility was high and weaker when it was low. Among youth users and non-users, message credibility did not moderate the indirect effect. Consistent with research from high-income countries, these findings highlight the importance of selecting imagery that will elicit negative emotional reactions and be perceived as credible. Differential effects among adults and youth highlight the importance of pre-testing images. Copyright © 2017 Elsevier Ltd. All rights reserved.

In situ testing of Savannah River Plant [SRP] waste glass is an important component in ensuring technical and public confidence in the safety and effective performance of the wasteforms. Savannah River Laboratory [SRL] is currently involved in joint programs involving field testing of SRP waste in Sweden, Belgium, and the United Kingdom. Most recently, this in situ effort has been expanded to include the first field tests to be conducted in the United States, involving burial of a variety of simulated nuclear waste systems. This new effort, called the Materials Interface Interactions Tests or MIIT, is a program jointly conducted by Sandia National Laboratory/Waste Isolation Pilot Plant [WIPP] and SRL. Over 1800 samples, supplied by the United States, France, West Germany, Belgium, Canada, Japan, and the United Kingdom, were buried approximately 650m below the earth's surface in the salt geology at WIPP, near Carlsbad, New Mexico. The MIIT program is one of the largest cooperative efforts ever undertaken in the waste management field; the data produced from these tests are designed to benefit a wide cross-section of the waste management community. An earlier document provided an overview of the WIPP MIIT program and described its place in the waste glass assessment program at Savannah River. This document represents the second in this series and its objectives include: (1) providing a pictorial history of assembly and installation of wasteforms, metals, and geologic samples in WIPP; (2) providing 'finalized and completed' sample matrices for the entire 7-part MIIT program; (3) documenting final sample assemblies by the use of schematic drawings, including each sample, its orientation, and its environment; and (4) providing a complete listing of all samples and the means for managing analyses and resulting data

Western European influences on Post-Byzantine panel painting technique through binding media identification

Kouloumpi, E.; Lawson, G.; Pavlidis, B.

2006-01-01

Post-Byzantine is called the period after the invasion of the Ottomans in Constantinople, the capital of Byzantium in 1453, which lasted until the establishment of the first Greek State in 1836. The Post - Byzantine era is one of the most important artistic periods of the Neo-Hellenic Pictorial Art, since, through cultural exchanges with Western Europe, it sets the fundaments for oil painting. The thematology changes from religious to civil, the technique changes from egg yolk to egg-oil emulsion in order to end up to pure oil painting and finally, it opens 'the gates' for the modern artistic movements of the world. The current research is focused on the study of the effects of western influences on the technique and pictorial characteristics of the post-Byzantine icons by the study of any changes in the pigment's binding media through scientific analyses (SEM-EDX, micro-FTIR and GC), as well as of any changes in the painting style of the icons through comparison with both Byzantine and western painting standards. Research never ends and the results of this work give rise to further analysis, in order to throw some light to this transitional period of art. (Author)

What about artistic creativity following a cerebral lesion? We studied the case of a prominent right-handed Swedish painter and sculptor who suffered a cerebral hemorrhage at the age of 55 years. The patient displayed a lesion of the left capsular lenticular region, which resulted in a right hemiplegia and sensory loss, with aphasia of the subcortical type. The linguistic impairments recovered well but at 1 year postonset, the right hand was still completely paralyzed. After a period of a few weeks, during which the patient refused to use his nondominant hand, he produced his first left-handed drawing, and by 1 year postonset, he had once again resumed an intensive artistic activity using his nondominant hand. The pictorial works were reviewed by several renowned art specialists: changes of style and even of contents were judged without loss of artistic quality. The result was described as a gain in emotional and artistic intensity. We discuss our observation in the context of the literature and focus on the crucial role of cerebral dominance and hand preference. We conclude that pictorial creativity and language are distinct forms of expressions.

A system and methods through which pictorial views of an object's configuration, arranged in a hierarchical fashion, are navigated by a person to establish a visual context within the configuration. The visual context is automatically translated by the system into a set of search parameters driving retrieval of structured data and content (images, documents, multimedia, etc.) associated with the specific context. The system places ''hot spots'', or actionable regions, on various portions of the pictorials representing the object. When a user interacts with an actionable region, a more detailed pictorial from the hierarchy is presented representing that portion of the object, along with real-time feedback in the form of a popup pane containing information about that region, and counts-by-type reflecting the number of items that are available within the system associated with the specific context and search filters established at that point in time.

Ultrasound simulation allows students to virtually explore internal anatomy by producing accurate, moving, color, three-dimensional rendered slices from any angle or approach leaving the organs and their relationships intact without requirement for consumables. The aim was to determine the feasibility and efficacy of self-directed learning of cardiac anatomy with an ultrasound simulator compared to cadavers and plastic models. After a single cardiac anatomy lecture, fifty university anatomy students participated in a three-hour supervised self-directed learning exposure in groups of five, randomized to an ultrasound simulator or human cadaveric specimens and plastic models. Pre- and post-tests were conducted using pictorial and non-pictorial multiple-choice questions (MCQs). Simulator students completed a survey on their experience. Four simulator and seven cadaver group students did not attend after randomization. Simulator use in groups of five students was feasible and feedback from participants was very positive. Baseline test scores were similar (P = 0.9) between groups. After the learning intervention, there was no difference between groups in change in total test score (P = 0.37), whether they were pictorial (P = 0.6) or non-pictorial (P = 0.21). In both groups there was an increase in total test scores (simulator +19.8 ±12.4%% and cadaver: +16.4% ± 10.2, P human cadaveric prosections for learning cardiac anatomy. © 2014 American Association of Anatomists.

Spatial skills have been linked to better performance in mathematics. The purpose of this study was to examine the relationship between teacher spatial skills and their instruction, including teacher content and pedagogical knowledge, use of pictorial representations, and use of gestures during geometry instruction. Fifty-six middle school teachers participated in the study. The teachers were administered spatial measures of mental rotations and spatial visualization. Next, a single geometry class was videotaped. Correlational analyses revealed that spatial skills significantly correlate with teacher's use of representational gestures and content and pedagogical knowledge during instruction of geometry. Spatial skills did not independently correlate with the use of pointing gestures or the use of pictorial representations. However, an interaction term between spatial skills and content and pedagogical knowledge did correlate significantly with the use of pictorial representations. Teacher experience as measured by the number of years of teaching and highest degree did not appear to affect the relationships among the variables with the exception of the relationship between spatial skills and teacher content and pedagogical knowledge. Teachers with better spatial skills are also likely to use representational gestures and to show better content and pedagogical knowledge during instruction. Spatial skills predict pictorial representation use only as a function of content and pedagogical knowledge. © 2017 The British Psychological Society.

Full text: We aim to demonstrate the anatomy and pathology of the hippocampus. It is important that radiologists distinguish normal and abnormal hippocampal hippocampal MR appearances, since hippocampal sclerosis is the commonest cause of surgically treatable temporal lobe epilepsy. The detailed anatomy of the hippocampus is reviewed and correlated with normal MR appearances. Our radiology database was reviewed to determine both common and unusual pathologies affecting the hippocampus. Most scans were performed for our large Comprehensive Epilepsy Program, for investigation of epilepsy of possible seizures. Less frequent indications included memory loss (acute or chronic), stroke, headache, and altered conscious state. Hippocampal sclerosis was the commonest MR abnormality. This was occasionally bilateral or associated with other pathology. Other common findings included mild hippocampal asymmetry, bilateral atrophy, or normal variants such as choroid fissure cysts. Other pathologies included cortical developmental malformations, infarction, posttraumatic gliosis, herpes, simplex encephalitis, paraneoplastic limbic encephalitis, vascular malformations, sarcoidosis, benign tumours such as gangliogliomas and dysembyoplastic neuroepithelial tumours (DNET) and malignant tumours. The hippocampus has a complex anatomy visible on high resolution MRI. In the clinical context of epilepsy, hippocampal sclerosis is an important pathology, but a range of conditions may affect the hippocampus, readily demonstrated by MRI.

Most described male breast lesions, such as gynecomastia, are benign. The overall incidence of male breast cancer is less than 3%. Like women, common presentations of male breast diseases are palpable lumps or tenderness. Physical examination, mammography and ultrasound are generally used for work-up of breast diseases in both women and men. However, men do not undergo screening mammograms; all male patients are examined in symptomatic cases only. Therefore, all male breast examinations are diagnostic, whereas the majority of the examinations for women are for screening purpose. The differentiation between benign and malignant breast lesions is important, especially for men, because the reported prognosis of male breast cancer is poor due to delayed diagnosis. In this article, we review the spectrum of male breast diseases, from benign to malignant, and illustrate their ultrasonographic and mammographic imaging features.

This thesis defends the musical quality of pictorial art as the absolute value of an artistic quest. Entendre the painting means experiencing its unfolding as space and time. The whole body becomes a receptacle for the rhythm of forms beyond the simple visual appreciation of an artwork. The pictorial form is felt as an entity in perpetual autogenesis, just as music and sound surround and invade us. Such conviction is anchored in the philosophical thought of Henri Maldiney and Erwin Straus : s...

Since the discovery of the Minoan and Mycenaean civilizations of Crete and Greek mainland, a systematic understanding has been gained of their material culture and social structures. Nevertheless, because of the absence of textual and pictorial evidence of medicine of the kind which exists in the contemporary societies of Egypt and the Near East, little work has been produced on the subject of disease and the practice of medicine in the period. However, new pathological evidence throws much light on this hitherto largely unknown aspect of their civilization.

Full Text Available Art and medicine have a relationship spanning millennia during which time they have collaborated to reach their mutual goals. Art is nourished by the human figure, illness and death to build renewed forms of beauty; medicine turns to art for aesthetics, humanism, history and sociology through artistic representations. Art provides information on many aspects related to medicine. Disease has conditioned the work of some painters and can explain aspects of the pictorial technique of some artistic movements. Art can also be used to train observational skills in students.

Live to work or love to work: work craving and work engagement.

Science.gov (United States)

Wojdylo, Kamila; Baumann, Nicola; Fischbach, Lis; Engeser, Stefan

2014-01-01

According to the theory of work craving, a workaholic has a craving for self-worth compensatory incentives and an expectation of relief from negative affect experienced through neurotic perfectionism and an obsessive-compulsive style of working. Research has shown that workaholism and work engagement should be considered as two distinct work styles with different health consequences. However, the mechanisms underlying the adoption of these work styles have been neglected. The present study proposes that work craving and work engagement are differentially associated with self-regulatory competencies and health. In particular, we expected that the working styles mediate the relationships between emotional self-regulation and health. In the cross-sectional study, 469 teachers from German schools completed online administered questionnaires. By means of structural equation modeling, we tested two indirect paths: a) from self-relaxation deficits via work craving to poor health and b) from self-motivation competencies via work engagement to good health. As expected, we found evidence that a) the negative relationship of self-relaxation deficits on health was partially mediated by work craving and b) the positive relationship of self-motivation competencies on health was partially mediated by work engagement. The present study emphasizes the importance of self-regulation competencies for healthy or unhealthy work styles. Whereas work craving was associated with a low ability to down-regulate negative emotions and poor health, work engagement was associated with a high ability to up-regulate positive emotions and good health.

2005-04-01

Little research has been conducted on the perceived competence of children with mild intellectual disabilities (MID). One of the reasons for the marked absence of research appears to be the lack of reliable and clearly valid measurement instruments for this particular group of children. In the present study, it was examined whether a pictorial scale originally designed to measure perceived competence in typically developing children could successfully be used with children with MID. The pictorial scale was administered to a group of 106 children with MID. The construct validity, reliability and stability of the scale were investigated. The results of the exploratory factor analyses and the confirmatory factor analyses supported the conceptual framework proposed. The construct validity was also supported by the pattern of intercorrelations between the subscales. The scale had adequate internal consistency and the stability analyses showed sufficient stability across a 4-month period. The findings show the psychometric properties of the pictorial scale to justify its use with children with MID.

Zograscopic viewing.

Science.gov (United States)

Koenderink, Jan; Wijntjes, Maarten; van Doorn, Andrea

2013-01-01

The "zograscope" is a "visual aid" (commonly known as "optical machine" in the 18th century) invented in the mid-18th century, and in general use until the early 20th century. It was intended to view single pictures (thus not stereographic pairs) with both eyes. The optics approximately eliminates the physiological cues (binocular disparity, vergence, accommodation, movement parallax, and image blur) that might indicate the flatness of the picture surface. The spatial structure of pictorial space is due to the remaining pictorial cues. As a consequence, many (or perhaps most) observers are aware of a heightened "plasticity" of the pictorial content for zograscopic as compared with natural viewing. We discuss the optics of the zograscope in some detail. Such an analysis is not available in the literature, whereas common "explanations" of the apparatus are evidently nonsensical. We constructed a zograscope, using modern parts, and present psychophysical data on its performance.

Organizing pneumonia (formerly named bronchiolitis obliterans with organizing pneumonia or BOOP) is a clinical, radiological and histological entity that is classified as an Interstitial Lung Disease. The understanding of this family of diseases has seen great progress over the past twenty years. CT presentation of organizing pneumonia is polymorphous but a few patterns have been recently recognized as being more specific to this diagnosis. The aim of this work is to summarize new understandings of the clinical and histological presentation of the disease and to review the most relevant CT features.

Akhmatova’s “Leonaderschi”: A Commentary on the Pictorial Reality

Directory of Open Access Journals (Sweden)

Alexander V. Markov

2017-12-01

Full Text Available This article explores why N. Nedobrovo mentioned Il Sodoma (Giovanni-Antonio Bazzi among the artists of da Vinci School in her poem that was of particular importance to Anna Akhmatova. The referenced studies by Merezhkovsky, Freud, and Muratov, explain the convergence of Sodoma’s art with the work of Leonardo da Vinci. The author argues, however, that the real reason of this convergence was the joke narrative of Vasari about Il Sodoma that was reinterpreted by the 20 th century authors in the spirit of “Romantic irony.” Placing “Romantic irony” in the context of the conversation about painting as the mirror of the world influenced Nedobrovo and Akhmatova and shaped their understanding of existence in terms of the “looking-glass.” Thus, the theme of the mirror in Akhmatova’s poetry, dominant in her poetic world, not only can be explained by autobiographical motives but also related to the mirror topoi in painting and Vasari’s story about Sodoma as the artist who was both serious and entertaining and building his own self-image on self-parody. This allows us attenuate the Doppelgänger motif in Akhmatova’s poetry.

Esas fuentes tan diversas –pintores del Trecento y el Quattrocento, el cubismo, el surrealismo, la pintura metafísica, el mundo clásico, el arte español, Velázquez, Vermeer, etc.– reflejan su progresiva evolución pictórica, que no presenta rupturas, y evidencian la admiración que siente hacia otros artistas y su conocimiento de la historia del arte antiguo y contemporáneo. Asimismo, algunas de sus obras, como sus vistas aéreas, sugieren su comparación con el impresionismo. El papel que juega la fotografía es un elemento fundamental en esta comparativa. La admiración que despierta no es sólo a nivel profesional, sino también humano. A través de las entrevistas, el receptor es consciente de la humanidad de este genio y del sentido e intención última de su obra.Abstract: Antonio López has been the recipient of many different influences throughout his artistic career, crowned by the unofficial title of main figure of Spanish Realism. These sources, that range from Trecento and Quattrocento paintings to Cubism, Surrealism, metaphysical painting, the classic world, Spanish art, Velázquez or Vermeer show a steady pictorial development and demonstrate his admiration for other artists and his knowledge of Ancient and Contemporary art history. In addition, his aerial views can be compared with Impressionism. Photography’s role is a basic element in this comparison. His works trigger the admiration both from a technical and a human point of view. By the interviews, the public is aware of the humanity of this genius as well as the meaning and the final intention of his work.

Remote operation: a selective review of research into visual depth perception.

Science.gov (United States)

Reinhardt-Rutland, A H

1996-07-01

Some perceptual motor operations are performed remotely; examples include the handling of life-threatening materials and surgical procedures. A camera conveys the site of operation to a TV monitor, so depth perception relies mainly on pictorial information, perhaps with enhancement of the occlusion cue by motion. However, motion information such as motion parallax is not likely to be important. The effectiveness of pictorial information is diminished by monocular and binocular information conveying flatness of the screen and by difficulties in scaling: Only a degree of relative depth can be conveyed. Furthermore, pictorial information can mislead. Depth perception is probably adequate in remote operation, if target objects are well separated, with well-defined edges and familiar shapes. Stereoscopic viewing systems are being developed to introduce binocular information to remote operation. However, stereoscopic viewing is problematic because binocular disparity conflicts with convergence and monocular information. An alternative strategy to improve precision in remote operation may be to rely on individuals who lack binocular function: There is redundancy in depth information, and such individuals seem to compensate for the lack of binocular function.

The Effect of Glosses on Incidental Vocabulary Learning of Iranian EFL learners

Full Text Available Reading passages contain many new words. Looking up every word in the dictionary and finding the exact meaning can be a difficult job for learners and may hinder the process of reading. Providing glosses can help learners deal with this issue. The objective of the present study is to make enquiries about the effect of glosses on incidental vocabulary learning. To this end, 45 Iranian EFL learners were selected from 70 according to their performance on KET test. Then they were divided into three groups of 15 randomly. Ten reading texts were selected and unfamiliar vocabularies were glossed in three ways: pictorial, textual and pictorial-textual glosses. Participants were required to read the texts under one of the three conditions. After the completion of ten sessions of treatment, participants were given a vocabulary post-test to measure vocabulary learning. The outcome of the study indicated that the group that received the combination of pictorial and textual glosses outperformed the other two groups. The findings can be of great importance for language teachers and material developers.

Pictorial layers in contemporary art: stabilization of an artwork made of chocolate and metal

Full Text Available We show in this article all the previous studies and the treatments performed over an interesting contemporary work by the artist Enriqueta Hueso. The artwork, made with contemporary and unconventional materials such as chocolate, iron and bronze, showed poor conservation conditions and needed a detailed analysis of all the differing factors which involved the act of intervention. In order to intervene according the differing factors, the artistic intention, the idea and the concept of the work were to be respected. Thus, all the performed treatments were limited by the need for keeping both the original appearance and the original materials' nature. This artwork was made to be touched and it demanded a consolidation treatment and protection against biological deterioration, as well as a good study on preventive conservation.

Using the concept of illness trajectory we analyse how the ambulance crews balance machine work, which involves continuously...... monitoring the equipment, comfort work, which is actions taken to relieve the pain or discomfort of the patient, and sentimental work, which is care for the patient’s physical and mental well-being, often verbal in nature. The analysis shows that comfort and sentimental work often takes priority over machine...... work, but also that this has negative consequences. Equipment for use in ambulances should aim at supporting the ambulance crews in competently and dynamically balancing the different types of work and should, consequently, avoid binding the crew’s attention for unbroken periods of time....

La distanciation dans l’œuvre régionaliste de Grant Wood comme moyen de mise en échec du nationalisme “Tactics of Estrangement”: Distance and the Negation of Nationalism in Grant Wood’s Regionalist Paintings

Full Text Available Regionalist painter Grant Wood’s works complied with much of the regionalist ideology as defined by critic Thomas Craven with its nationalism and its rejection of European Modernism. Wood displayed his concern for an American idiom in many of his works. However, while they use pictorial elements that suggest acceptance of the nationalist rhetoric of both Craven and the New Deal art projects, Wood’s works actually show aesthetic preoccupations similar to those of Modernists, and a growing distance from the mythic representations of America often found in regionalist art. While Wood empathises with his countrymen, he also introduces elements within the narrative, and aesthetic elements, that contradict his acceptance of the dominant discourse. Strange, inappropriate and unexpected incursions question the theme and aesthetic affiliation of a work. This deviation, this escape from the frame imposed by Craven and the New Deal, this estrangement, can work as a questioning of America, its values, its myths and its self-representation.

Neuroscientific investigations regarding aspects of emotional experiences usually focus on one stimulus modality (e.g., pictorial or verbal). Similarities and differences in the processing between the different modalities have rarely been studied directly. The comparison of verbal and pictorial emotional stimuli often reveals a processing advantage of emotional pictures in terms of larger or more pronounced emotion effects evoked by pictorial stimuli. In this study, we examined whether this picture advantage refers to general processing differences or whether it might partly be attributed to differences in visual complexity between pictures and words. We first developed a new stimulus database comprising valence and arousal ratings for more than 200 concrete objects representable in different modalities including different levels of complexity: words, phrases, pictograms, and photographs. Using fMRI we then studied the neural correlates of the processing of these emotional stimuli in a valence judgment task, in which the stimulus material was controlled for differences in emotional arousal. No superiority for the pictorial stimuli was found in terms of emotional information processing with differences between modalities being revealed mainly in perceptual processing regions. While visual complexity might partly account for previously found differences in emotional stimulus processing, the main existing processing differences are probably due to enhanced processing in modality specific perceptual regions. We would suggest that both pictures and words elicit emotional responses with no general superiority for either stimulus modality, while emotional responses to pictures are modulated by perceptual stimulus features, such as picture complexity.

Pictorial and tangible paired-stimulus preference assessments were compared with 4 adolescents with developmental disabilities. In the tangible assessment, two stimuli were placed in front of the participant on each trial; in the pictorial assessment, two line drawings were placed in front of the participant on each trial. Approach responses were recorded for each assessment. The assessments generated similar preference hierarchies for all participants. Reinforcer assessments confirmed that response rates were higher when access to high-preference items was available than when low-preference items were available. Implications for assessing preferences and selecting items to be used in training programs are discussed.

Picture and word recall was examined in conjunction with list organization. 60 subjects studied a list of 30 items, either words or their pictorial equivalents. The 30 words/pictures, members of five conceptual categories, each represented by six exemplars, were presented either blocked by category or in a random order. While pictures were recalled better than words and a standard blocked-random effect was observed, the interaction indicated that the recall advantage of a blocked presentation was restricted to the word lists. A similar pattern emerged for clustering. These findings are discussed in terms of limitations upon the pictorial superiority effect.

Full Text Available The present study examined the relationship between family-work conflict, job performance and selected work and family characteristics in a sample of working mothers employed at a large retail organization. The hypothesis of a negative relationship between family-work conflict and job performance was rejected. Married women reported significantly higher family-work conflict than unmarried women, while women in the highest work category gained the highest job performance rating. More than half the sample indicated that paid work was more important than their housework and reported that their working had a positive impact on their families. The findings are discussed in relation to the changing work and family identities of non-career women.

Work-family conflicts and work performance.

Science.gov (United States)

Roth, Lawrence; David, Emily M

2009-08-01

Prior research indicates that work-family conflict interferes with family far more than it interferes with work. Conservation of resources provides a possible explanation: when shifting resources from family is no longer sufficient to maintain satisfactory work performance, then workers must acquire additional resources or reduce investments in work. One source of such additional resources could be high performance peers in the work group. The performance of workers with resource-rich peers may be less adversely affected by work-family conflict. In this study, 136 employees of a wholesale distribution firm (61% women, 62% minority) working in groups of 7 to 11 in manual labor and low-level administrative jobs rated their own work-to-family conflict. Their supervisors rated workers' performance. Hierarchical regression analysis indicated that work-to-family conflict increasingly adversely affected job performance as work group performance decreased. Hence, work group performance may be an important moderator of the effects of work-family conflict.

Work-life conflict has been poorly studied as a cause of ill-health in occupational medicine. To study associations between physical and psychosocial working conditions, including work-life conflict on the one hand and general, physical and mental health outcomes on the other. Cross-sectional data were used from an employee survey among the workforces of four medium-sized and large companies in Switzerland. Physical work factors included five demands and exposures such as heavy loads, repetitive work and poor posture. Psychosocial factors included 14 demands and limited resources such as time pressure, overtime, monotonous work, job insecurity, low job autonomy, low social support and work-life conflict. Health outcomes studied were self-rated health, sickness absence, musculoskeletal disorders, sleep disorders, stress and burnout. There was a response rate of 49%; 2014 employees participated. All adverse working conditions were positively associated with several poor health outcomes in both men and women. After mutual adjustment for all work factors and additional covariates, only a few, mainly psychosocial work factors remained significant as risk factors for health. Work-life conflict, a largely neglected work-related psychosocial factor in occupational medicine, turned out to be the only factor that was significantly and strongly associated with all studied health outcomes and was consistently found to be the strongest or second strongest of all the studied risk factors. Even in an industrial work environment, psychosocial work factors, and particularly work-life conflict, play a key role and need to be taken into consideration in research and workplace health promotion.

Full Text Available Abstract Background Surveys have provided evidence that tobacco use is widely prevalent amongst the youth in Pakistan. Several reviews have evaluated the effectiveness of various tobacco control programs, however, few have taken into account the perceptions of students themselves regarding these measures. The aim of this study was to determine the most effective anti-smoking messages that can be delivered to high-school students in Pakistan, based on their self-rated perceptions. It also aimed to assess the impact of pictorial/multi-media messages compared with written health warnings and to discover differences in perceptions of smokers to those of non-smokers to health warning messages. Methods This study was carried out in five major cities of Pakistan in private English-medium schools. A presentation was delivered at each school that highlighted the well-established health consequences of smoking using both written health warnings and pictorial/multi-media health messages. Following the presentation, the participants filled out a graded questionnaire form, using which they rated the risk-factors and messages that they thought were most effective in stopping or preventing them from smoking. The Friedman test was used to rank responses to each of the questions in the form. The Wilcoxon Signed Rank test used to analyze the impact of pictorial/multi-media messages over written statements. The Mann Whitney U test was used to compare responses of smokers with those of non-smokers. Results Picture of an oral cavity cancer, videos of a cancer patient using an electronic voice box and a patient on a ventilator, were perceived to be the most effective anti-smoking messages by students. Addiction, harming others through passive smoking and impact of smoking on disposable incomes were perceived to be less effective messages. Pictorial/multi-media messages were perceived to be more effective than written health warnings. Health warnings were perceived as

The Havana City historical center is being recuperated in the las years. Numerous are the colonial houses with values typical wall painting as internal decoration that need to be investigated and restored. The pigment identification is essential to have knowledge about pictorial technique and to help and monitor the restoration process. The identification of inorganic pigments in the Havana colonial wall painting has been not almost studied. The opportunity to have a new Portable XRF system in the Archaeometry laboratory of the Conservation and Restoration Gabinet of Havana Historitian Office allows to investigate the wall painting, samples that because of its more of this nature it would be impossible to move to the laboratory for non destructive analysis. The most of the pigment are made of inorganic elements and they can be identified property by XRF technique. All complete archaeometric investigation has to use several technique and to work in a multidisciplinary research team to give a fundamental answer about the past, The suitable techniques selection to employ depends of the art Historitian and archaeologist's questions. The pictorial technique are traditionally investigated using stratigraphical information obtained by Optical Microscopy and organic compound determination by Gas Chromatography. The global analysis of the results from the different employed techniques and the discussion from the restaurateur point of view is presented

This study aims at modelling the relationship between the number of work hours per week and cortisol variation across 3 days by comparing non-working day to working day in a population of day-shift workers. Questionnaire data and saliva samples for cortisol analysis were collected on 132 day-shift workers employed in 13 workplaces in Canada. Consenting workers provided 5 saliva samples a day (awaking, 30 min after awaking, 2 p.m., 4 p.m., bedtime) repeated 3 times (Saturday, Tuesday, Thursday) over a week, to provide measures at work and non-work times and settings. Multilevel regression models were estimated from cortisol measurements at each occasion within a day at level-1, days at level-2 and workers at level-3. Controlling for gender and age, results revealed significant variations in salivary cortisol concentration between sample, day and worker levels. Cortisol increases linearly from non-working day to work days and work hours per week interacted with days, revealing a positive association between the number of work hours per week and cortisol concentrations during these days. Work hours per week did not interact with awaking, 30 min after awaking, 2 p.m., 4 p.m., and bedtime cortisol concentrations. Gender and age had neither main effects nor interaction effects. No significant cortisol variations were found between workplaces. These results suggest that work hours act as a stressor that is associated with significant variations in cortisol concentrations over working days. Non-working days may contribute to stress reduction in workers who experience longer work hours.

Full Text Available Pictorial work of Antonello da Messina during the Sicilian period (1455-60 is considered less fruitful and less mature than during his stay in Venice (ca 1474-1476. While some art critics consider the painting “Saint Jerome in the study” a work of the first period, others believe that it was produced during the Venice period. The Authors analysed the plumage characters of the Rock Partridge, Alectoris graeca, depicted with symbolic significance in the painting, to try the identification of the population which the subject used as model could belong to. However, they conclude that the identification as a Sicilian as well as an Alpine Rock Partridge is doubtful and in this case the plumage of the bird depicted does not help to resolve the controversy of painting dating.

2007-10-01

This article examines the relationship among work-family conflict and enhancement, organizational work-family culture, and four work outcomes for 489 working women over the age of 50. Survey results from two U.S. health care organizations and one U.S. financial services organization indicate that older working women experience differing amounts of work-to-family conflict, family-to-work conflict, work-to-family enhancement, and family-to-work enhancement. Hypotheses relating organizational work-family culture to work-family conflict and enhancement were partially supported, and hypotheses relating conflict and enhancement to four work outcomes were partially supported. Work-to-family conflict and work-to-family enhancement partially mediate the relationship between organizational work-family culture and selected work outcomes. Implications for theory and practice, limitations of this study, and directions for future research are also presented.

2011-01-01

Call-centre workers encounter major psychosocial pressures, including high work intensity and undesirable working hours. Little is known, however, about whether these pressures vary with employment status and how they affect work-life conflict and health. Questionnaire data were collected from 179 telephone operators in Sydney, Australia, of whom 124 (69.3%) were female and 54 (30.2%) were male. Ninety-three (52%) were permanent full-time workers, 37 (20.7%) were permanent part-time, and 49 (27.4%) were casual employees. Hypothesised structural relationships between employment status, working hours and work organisation, work-life conflict and health were tested using partial least squares modelling in PLS (Chin, 1998). The final model demonstrated satisfactory fit. It supported important elements of the hypothesised structure, although four of the proposed paths failed to reach significance and the fit was enhanced by adding a path. The final model indicated that casual workers reported more variable working hours which were relatively weakly associated with greater dissatisfaction with hours. The interaction of schedule control and variability of hours also predicted dissatisfaction with hours. Conversely, permanent workers reported greater work intensity, which was associated with both lower work schedule control and greater work-life conflict. Greater work-life conflict was associated with more fatigue and psychological symptoms. Labour market factors and the undesirability of longer hours in a stressful, high-intensity work environment appear to have contributed to the results.

The research question is "How does a diabetes mellitus (DM) pictorial diary handbook (PDHB) affect the knowledge, practice, and HbA1c among patients with DM type 2?" The aim of this study was to evaluate the effect of a PDHB program among middle-aged and elderly patients with DM type 2 in primary care units in Thailand. A quasi-experimental study design was applied. DM type 2 patients were recruited in the PDHB program by a simple random sampling method. The 3-month program consisted of a weekly health education structured for ~20 minutes, a 15-minute group activity training, a 10-minute individual record of participants' knowledge and practice regarding diet control, exercise, oral hypoglycemic drug taking, diet, self-care, alcohol consumption, smoking, weight management, and HbA1c, and a 15- to 30-minute home visit as well as the PDHB for recording self-care behavior daily. The control group received only the usual diabetes care. The primary expected outcomes were changes in HbA1c from the baseline data to 3 months after the program compared between the intervention and control groups. The secondary expected outcomes were compared within the intervention group. The third expected outcomes were changes in the mean score of knowledge and practice from baseline to 3 months after the program within and between the intervention and control groups. Compared with the baseline data, there was no significant difference in HbA1c, knowledge, and practice mean score between the intervention and control groups. However, there was a significant difference in HbA1c, knowledge, and practice mean score in the intervention group after they received a 3-month PDHB program and within the intervention group ( p -value =0.00). The PDHB program was effective in lowering HbA1c while also improving the mean score of knowledge and practice among elderly patients with DM type 2. However, larger and longer trial studies will be needed to evaluate the sustainability of this program.

Data were analyzed on the sleep-wake cycle in 863 teenage students in São Paulo, Brazil. Adjusted analyses were performed to compare sleep duration in working and non-working students. 18.4% of the group worked, and 52% of the working students slept eight hours or less per night. Prevalence of short sleep duration was higher in working students of both sexes (males, p = 0.017; females, p Working students showed short sleep duration in the analysis adjusted for socioeconomic status, but short sleep was more frequent in older adolescents (p = 0.004) and in lower (p = 0.001) and middle (p = 0.011) socioeconomic classes. Although more working students were in night school, in the model adjusted for gender and socioeconomic status, working students in afternoon courses showed higher prevalence of short sleep duration (PR = 2.53; 95%CI: 1.68-4.12).

Precarious or temporary work is associated with adverse outcomes including low control over working hours, work-life conflict and stress. The rise in precarious employment is most marked in the service sector but little research has been done on its health effects in this sector. This study compares permanent and temporary workers in the hotel industry, where working hours are highly variable. Survey data from 150 workers from eight 3-Star hotels in urban and regional areas around Sydney were analyzed. Forty-five per cent were male and 52 per cent were female. Fifty four per cent were permanent full-time and 46 per cent were temporary workers. The effects of employment status on perceived job security, control over working hours, and work-life conflict are investigated using PLS-Graph 3.0. The effects of control over working hours, on work-life conflict and subsequent health outcomes are also explored. Temporary workers perceived themselves as less in control of their working hours, than permanent workers (β = .27). However, they also reported lower levels of work intensity (β = .25) and working hours (β = .38). The effects of low hours control (β = .20), work intensity (β = .29), and excessive hours (β = .39) on work-life conflict (r² = .50), and subsequent health effects (r² = .30), are illustrated in the final structural equation model.

To examine the associations of age, lifestyle and work-related factors, and particularly work engagement with the work ability index (WAI) and its sub-dimensions. Step-wise regression analysis with a sample of Finnish firefighters (n = 403) was used. The outcome variables were the WAI and its six sub-dimensions. The independent variables consisted of age, lifestyle variables (alcohol consumption, BMI, smoking, physical exercise, and sleep problems), working conditions (job demands, physical workload, supervisory relations, and task resources), and work engagement. The outcome variables and all the variables related to lifestyle, working conditions, and work engagement were measured in 2009. Work ability at baseline 10 years earlier was adjusted for in the models. Work engagement, age, physical exercise, sleep problems, and physical workload were associated with the WAI. All independent variables, except BMI and alcohol consumption, were associated with at least one sub-dimension of the WAI after controlling the baseline WAI. Lifestyle variables, working conditions, and work engagement were more strongly related to the subjective WAI sub-dimensions than to the two more objective WAI sub-dimensions. Work engagement was significantly associated with work ability even after adjusting for various factors, indicating its importance in promoting work ability. Other key factors for good work ability were frequent exercise, good sleep, non-smoking, low job demands, low physical workload, and high task resources. More specifically, this study suggests that in maintaining work ability, it is valuable not only to promote lifestyle factors or working conditions, but also to enhance employees' positive state of work engagement.

These days physicians' work is characterized by an increase in economic demands, pressure and challenges in establishing a balance between work and family life. The current study investigates the relationship between physicians' job demands and resources, perceived job stress, work-family conflict, work engagement and job satisfaction. 564 clinicians specialising in different medical fields participated in the cross-sectional study. Self-administered questionnaires, including the COPSOQ and the UWES- Scale were administered. Our results illustrated significant relationships between physicians' work engagement and their job satisfaction as well as between job stress and work family conflict. Moreover, perceived job stress moderated the effect of high job demands on work family conflict. In addition, significant gender differences have been found in perceived stress levels, work family conflict and work engagement. This study proves and verified associations between work engagement, work-family conflict, job demands and resources that may influence employees' satisfaction. Implications for both working physicians and hospital management are given.

Work values influence our attitudes and behavior at work, but they have rarely been explored in the context of work stress. The aim of this research was thus to test direct and moderating effects of Chinese work values (CWV) on relationships between work stressors and work well-being among employees in the Greater China region. A self-administered survey was conducted to collect data from three major cities in the region, namely Beijing, Hong Kong, and Taipei (N = 380). Work stressors were negatively related to work well-being, whereas CWV were positively related to work well-being. In addition, CWV also demonstrated moderating effects in some of the stressor-job satisfaction relationships.

We present a new method based on a Bayesian analysis to identify new members of nearby young kinematic groups. The analysis minimally takes into account the position, proper motion, magnitude, and color of a star, but other observables can be readily added (e.g., radial velocity, distance). We use this method to find new young low-mass stars in the β Pictoris and AB Doradus moving groups and in the TW Hydrae, Tucana-Horologium, Columba, Carina, and Argus associations. Starting from a sample of 758 mid-K to mid-M (K5V-M5V) stars showing youth indicators such as Hα and X-ray emission, our analysis yields 214 new highly probable low-mass members of the kinematic groups analyzed. One is in TW Hydrae, 37 in β Pictoris, 17 in Tucana-Horologium, 20 in Columba, 6 in Carina, 50 in Argus, 32 in AB Doradus, and the remaining 51 candidates are likely young but have an ambiguous membership to more than one association. The false alarm rate for new candidates is estimated to be 5% for β Pictoris and TW Hydrae, 10% for Tucana-Horologium, Columba, Carina, and Argus, and 14% for AB Doradus. Our analysis confirms the membership of 58 stars proposed in the literature. Firm membership confirmation of our new candidates will require measurement of their radial velocity (predicted by our analysis), parallax, and lithium 6708 Å equivalent width. We have initiated these follow-up observations for a number of candidates, and we have identified two stars (2MASSJ01112542+1526214, 2MASSJ05241914-1601153) as very strong candidate members of the β Pictoris moving group and one strong candidate member (2MASSJ05332558-5117131) of the Tucana-Horologium association; these three stars have radial velocity measurements confirming their membership and lithium detections consistent with young age.

The impact of working time arrangements (WTA) on health has been studied extensively. Still, little is known about the interrelation between work schedules, working hours, and depressed mood. For work schedules, the underlying assumptions regarding depressed mood refer to a disturbance of social and biological rhythms, whereas for working hours, the assumptions relate to workload and work capacity. Conversely, depressed mood may urge an employee to adjust his/her work schedule and/or number of working hours/week (h/wk). The aim of this study was to assess the association between work schedule and working hours with depressed mood. Using baseline data from the Maastricht Cohort Study, depressed mood in day work was compared with depressed mood in different shiftwork schedules (n = 8843). Within day work, several categories of working h/wk were studied in association with depressed mood (n = 7217). The association between depressed mood and several aspects of overtime was assessed separately. Depressed mood was measured with a dichotomous item: "Did you feel down every day over the last two weeks?" Separate logistic regression analyses were conducted for men and women, with adjustments for potential confounders. The odds ratio (OR) for depressed mood was greater for men involved in shiftwork than for men only involved in day work (three-shift OR = 2.05 [95% confidence interval, CI 1.52-2.77]; five-shift OR = 1.34 [95% CI 1.00-1.80]; irregular-shift OR = 1.79 [95% CI 1.27-2.53]). In female employees, five-shift work was associated with a higher prevalence of depressed mood (OR = 5.96 [95% CI 2.83-12.56]). Regarding the number of working h/wk, men working working 36-40 h/wk (OR = 2.73 [95% CI 1.35-5.52]). After conducting trend analyses, a significant decreasing trend was found in men, whereas an increasing trend was found in women working a high number of hours. Furthermore, a dose-response relationship was present in men regarding the number of overtime h/wk. This

Full Text Available Legal deposit has been the most important way of the acquisition of cartographic and pictorial library materials. For the period from 1948 to 1991, it represented up to 80 % of the inflow, composed mostly of postcards, obituaries, posters, congratulation cards, holly cards, calendars, maps, prints and atlases. High numbers of up to 5 000 copies were noted in the 70’s and 80’s. A notable decrease of items received through legal deposit was noted after 1991. Total inflow was between 1 000 and 2 000 copies per year. Traditional print maps and atlases still represent the majority of contemporary cartographic legal deposit inflow along with posters, postcards and calendars of pictorial materials.

Full Text Available Pictorial stimuli and words have been widely used to evaluate mnemonic processes in clinical settings, neuropsychological investigations, as well as in studies on the mechanisms underlying the phenomena of memory. However, there seem to be few studies of standardisation of pictures for research in this field. The present paper aimed at adapting the use of a set of pictures standardised for English speaking subjects for Portuguese speakers. Name agreement of 150 pictures was assessed in 100 high-school students. Ninety pictures were found to present the same name for over 90 subjects. Results yield data that may help create more controlled tests for the study of memory for pictorial stimuli in Brazil.

Astronomers are staring at a nearby star in hopes of seeing a giant baby of a planet—perhaps accompanied by dust clouds, rings, or newborn moons—pass across its face. Last week, the newest and tiniest telescope joined the vigil, when the French-built PicSat rode into orbit on an Indian rocket. It will be able to continuously monitor the star, β Pictoris, until chances of seeing the once-in-20-year transit event diminish in a few months' time. Astronomers are fascinated by β Pictoris, a bright star just 63 light-years away, because it is a natural laboratory for how solar systems form given its age of only 24 million years—an infant in stellar terms.

Pictorial Cross-Currents between Hawthorne and Atwood: Negotiating with the Dead

Full Text Available This paper analyzes the way in which a contemporary Canadian novelist, Margaret Atwood, uses the work of a canonical nineteenth-century American novelist, Nathaniel Hawthorne, to define her own position as a writer, while at the same time criticizing and transforming her precursor’s reflection on the writer’s task. I identify this process in Atwood’s 1996 novel, Alias Grace: it takes the form of a rewriting of Hawthorne’s most famous novel, The Scarlet Letter. An important connection between the two writers is their common use of visual art to pose, and potentially to resolve, the problems they encounter as artists in a hostile environment. Este artículo analiza cómo una novelista canadiense contemporánea, Margaret Atwood, utiliza la obra de un novelista norteamericano del siglo diecinueve, Nathaniel Hawthorne, para definir su propia posición como escritora, y también para criticar y transformar la reflexión de su predecesor. Este proceso se da en una novela de 1996, Alias Grace, en forma de una reescritura de la novela más famosa de Hawthorne, La letra escarlata. Una conexión importante entre los dos escritores es su uso del arte visual para plantear, y posiblemente resolver, los problemas que encuentran como artistas en un entorno hostil.

Knowledge work and work-related stress

Work-related stress is an increasing problem in Europe. Earlier studies have stated that knowledge-work comprises working conditions which reflect a good psychosocial environment. Recent Danish studies, however, point at stress being an increasing problem in knowledge-intensive companies...... with informally, individu-ally and incidentally. It is only when problems exist that enhanced support is offered in order to help an employee to cope or recover. As most workplace initiatives work at this tertiary level, the sources of work-related and organiza-tional stress are not reduced or eliminated...... as good and stimulating, but has on the other hand sides to it which can cause frustration and stress. The implication of organisational characteristics of the knowledge-intensive companies studied is a transfer of the responsibility for ones own working-life. Consequently, issues are dealt...

The epigenetic landscape in the course of time: Conrad Hal Waddington's methodological impact on the life sciences.

Science.gov (United States)

Baedke, Jan

2013-12-01

It seems that the reception of Conrad Hal Waddington's work never really gathered speed in mainstream biology. This paper, offering a transdisciplinary survey of approaches using his epigenetic landscape images, argues that (i) Waddington's legacy is much broader than is usually recognized--it is widespread across the life sciences (e.g. stem cell biology, developmental psychology and cultural anthropology). In addition, I will show that (ii) there exist as yet unrecognized heuristic roles, especially in model building and theory formation, which Waddington's images play within his work. These different methodological facets envisioned by Waddington are used as a natural framework to analyze and classify the manners of usage of epigenetic landscape images in post-Waddingtonian 'landscape approaches'. This evaluation of Waddington's pictorial legacy reveals that there are highly diverse lines of traditions in the life sciences, which are deeply rooted in Waddington's methodological work.

Melcher, David

2010-01-01

In contrast to our rich sensory experience with complex scenes in everyday life, the capacity of visual working memory is thought to be quite limited. Here our memory has been examined for the details of naturalistic scenes as a function of display duration, emotional valence of the scene, and delay before test. Individual differences in working memory and long-term memory for pictorial scenes were examined in experiment 1. The accumulation of memory for emotional scenes and the retention of these details in long-term memory were investigated in experiment 2. Although there were large individual differences in performance, memory for scene details generally exceeded the traditional working memory limit within a few seconds. Information about positive scenes was learned most quickly, while negative scenes showed the worst memory for details. The overall pattern of results was consistent with the idea that both short-term and long-term representations are mixed together in a medium-term 'online' memory for scenes.

Influence of Health Warnings on Beliefs about the Health Effects of Cigarette Smoking, in the Context of an Experimental Study in Four Asian Countries

Directory of Open Access Journals (Sweden)

2017-08-01

Full Text Available Cigarette package health warnings can be an important and low-cost means of communicating the health risks of smoking. We examined whether viewing health warnings in an experimental study influenced beliefs about the health effects of smoking, by conducting surveys with ~500 adult male smokers and ~500 male and female youth (age 16–18 in Beijing, China (n = 1070, Mumbai area, India (n = 1012, Dhaka, Bangladesh (n = 1018, and Republic of Korea (n = 1362. Each respondent was randomly assigned to view and rate pictorial health warnings for 2 of 15 different health effects, after which they reported beliefs about whether smoking caused 12 health effects. Respondents who viewed relevant health warnings (vs. other warnings were significantly more likely to believe that smoking caused that particular health effect, for several health effects in each sample. Approximately three-quarters of respondents in China (Beijing, Bangladesh (Dhaka, and Korea (which had general, text-only warnings thought that cigarette packages should display more health information, compared to approximately half of respondents in the Mumbai area, India (which had detailed pictorial warnings. Pictorial health warnings that convey the risk of specific health effects from smoking can increase beliefs and knowledge about the health consequences of smoking, particularly for health effects that are lesser-known.

The role of fear of movement and injury in selective attentional processing in patients with chronic low back pain: a dot-probe evaluation.

Roelofs, Jeffrey; Peters, Madelon L; Fassaert, Thijs; Vlaeyen, Johan W S

2005-05-01

The present study sought to investigate to what extent patients with chronic low back pain and pain-free control subjects selectively attend to pain-related stimuli as measured with 2 dot-probe tasks with word stimuli and pictorial stimuli. Selective attentional processing was measured by means of 3 indices: the bias index, a congruency effect, and an incongruency effect. Pain-related fear as a trait measure (Tampa Scale for Kinesiophobia [TSK]) was expected to be positively associated with all indices of selective attentional processing of pain stimuli. Results were analyzed with repeated-measures analysis of variance. An incongruency effect was found for patients and to a significantly less degree for pain-free control subjects on the dot-probe task with pictorial stimuli, indicating that pain patients have difficulty disengaging from threat pictures. Pain-related fear as a trait measure (TSK) was not associated with selective attentional processing of word and pictorial stimuli in either pain patients or control subjects. Results from the present study are discussed, and directions for future research are provided. Demonstrating difficulty to disengage from threat might be clinically relevant because patients might pay less attention to fear-disconfirming information and remain engaged in avoidance, which might eventually lead to prolonged anxiety states.

Attentional bias in smokers: exposure to dynamic smoking cues in contemporary movies.

Lochbuehler, Kirsten; Voogd, Hubert; Scholte, Ron H J; Engels, Rutger C M E

2011-04-01

Research has shown that smokers have an attentional bias for pictorial smoking cues. The objective of the present study was to examine whether smokers also have an attentional bias for dynamic smoking cues in contemporary movies and therefore fixate more quickly, more often and for longer periods of time on dynamic smoking cues than non-smokers. By drawing upon established methods for assessing attentional biases for pictorial cues, we aimed to develop a new method for assessing attentional biases for dynamic smoking cues. We examined smokers' and non-smokers' eye movements while watching a movie clip by using eye-tracking technology. The sample consisted of 16 smoking and 17 non-smoking university students. Our results confirm the results of traditional pictorial attentional bias research. Smokers initially directed their gaze more quickly towards smoking-related cues (p = 0.01), focusing on them more often (p = 0.05) and for a longer duration (p = 0.01) compared with non-smokers. Thus, smoking cues in movies directly affect the attention of smokers. These findings indicate that the effects of dynamic smoking cues, in addition to other environmental smoking cues, need to be taken into account in smoking cessation therapies in order to increase successful smoking cessation and to prevent relapses.

The Ambiguity of Work: Work Practice Stories of Meaningful and Demanding Consultancy Work

Directory of Open Access Journals (Sweden)

Didde Maria Humle

2014-03-01

Full Text Available This article contributes to the current debate among organizational and work-life researchers on the double-sided nature of knowledge work, which offers great freedom and satisfaction on the one hand and the potential to be overly demanding and stressful on the other. This contribution involves drawing on the results of an ethnographic case study of a consultancy house; more specifically, it comprises an exploration of the narrative identity work of consultants as they perform work practice stories of self, work, and the organization negotiating why the work they do is both challenging and rewarding. The type of knowledge work explored is characterized by its immaterial nature in the sense that the primary input is the competences, knowledge, and commitment of the consultants and the output is the joy, success, and satisfaction of candidates, clients, and collaborators. The article contributes by showing that some of the elements perceived to make the work meaningful and rewarding are the same ones also described as potentially demanding and challenging. Furthermore, the article contributes by arguing that studying work practice stories as (antenarrative identity work provides a rich source of empirical material in the examination of how we create meaning in relationship to the work we do and the organizations by which we are employed.

Macroscopic brain dynamics during verbal and pictorial processing of affective stimuli.

Science.gov (United States)

Keil, Andreas

2006-01-01

Emotions can be viewed as action dispositions, preparing an individual to act efficiently and successfully in situations of behavioral relevance. To initiate optimized behavior, it is essential to accurately process the perceptual elements indicative of emotional relevance. The present chapter discusses effects of affective content on neural and behavioral parameters of perception, across different information channels. Electrocortical data are presented from studies examining affective perception with pictures and words in different task contexts. As a main result, these data suggest that sensory facilitation has an important role in affective processing. Affective pictures appear to facilitate perception as a function of emotional arousal at multiple levels of visual analysis. If the discrimination between affectively arousing vs. nonarousing content relies on fine-grained differences, amplification of the cortical representation may occur as early as 60-90 ms after stimulus onset. Affectively arousing information as conveyed via visual verbal channels was not subject to such very early enhancement. However, electrocortical indices of lexical access and/or activation of semantic networks showed that affectively arousing content may enhance the formation of semantic representations during word encoding. It can be concluded that affective arousal is associated with activation of widespread networks, which act to optimize sensory processing. On the basis of prioritized sensory analysis for affectively relevant stimuli, subsequent steps such as working memory, motor preparation, and action may be adjusted to meet the adaptive requirements of the situation perceived.

Blended working: for whom it may (not work.

Directory of Open Access Journals (Sweden)

Nico W Van Yperen

Full Text Available Similarly to related developments such as blended learning and blended care, blended working is a pervasive and booming trend in modern societies. Blended working combines on-site and off-site working in an optimal way to improve workers' and organizations' outcomes. In this paper, we examine the degree to which workers feel that the two defining features of blended working (i.e., time-independent working and location-independent working enhance their own functioning in their jobs. Blended working, enabled through the continuing advance and improvement of high-tech ICT software, devices, and infrastructure, may be considered beneficial for workers' perceived effectiveness because it increases their job autonomy. However, because blended working may have downsides as well, it is important to know for whom blended working may (not work. As hypothesized, in a sample of 348 workers (51.7% women, representing a wide range of occupations and organizations, we found that the perceived personal effectiveness of blended working was contingent upon workers' psychological need strength. Specifically, the perceived effectiveness of both time-independent working and location-independent working was positively related to individuals' need for autonomy at work, and negatively related to their need for relatedness and need for structure at work.

Research purpose: The aim of the study was to investigate the relationships amongst psychological meaningfulness, work engagement and organisational commitment and to test for a possible mediation effect of work engagement on the relationship between psychological meaningfulness and organisational commitment. Motivation for the study: Managers have to rethink ways of improving productivity and performance at work, due to the diverse, and in some instances escalating, needs of employees (e.g. financial support to uphold their interest in and enjoyment of working. Research approach, design and method: A quantitative approach was employed to gather the data for the study, utilising a cross-sectional survey design. The sample (n = 415 consisted of working employees from various companies and positions in Gauteng, South Africa. Main findings: The results confirmed a positive relationship between psychological meaningfulness, work engagement and organisational commitment. Further, psychological meaningfulness predicts work engagement, whilst psychological meaningfulness and work engagement predict organisational commitment. Practical/managerial implications: Employers identifying their employees’ commitment patterns and mapping out strategies for enhancing those that are relevant to organisational goals will yield positive work outcomes (e.g. employees who are creative, seek growth or challenges for themselves. Contribution/value-add: This study contributes to the literature through highlighting the impact that meaningful work has on sustaining employee commitment to the organisation.

The Multiband Imaging Photometer for Spitzer (MIPS) provides long-wavelength capability with imaging bands at 24, 70, and 160 um. We will present the MIPS images of the Fabulous Four Debris Disks: Beta Pictoris (A5 V), Epsilon Eridani (K2 V), Fomalhaut (A3 V) and Vega (A0 V). These systems discovered by IRAS possess large far-infrared excess emission above photosphere, indicating the existence of a circumstellar dusty disk. Given the main-sequence ages of these stars ( ˜12 Myr for Beta Pictoris, ˜730 Myr for Epsilon Eridani, ˜200 Myr for Fomalhaut, and ˜350 Myr for Vega), the dust in the systems could not be primordial as it would have been removed by radiation pressure and Poynting-Robertson drag on relatively short time scales ( ˜1E4 yr). The second-generation dust in such debris disks is thought to arise primarily from collisions between planetesimals (asteroids) and from cometary activity; however, details about the debris formation and evolution are not well understood. With the sensitivity and angular resolution of the Spitizer Space Telescope, the structures of these nearby debris disks were mapped in great detail to study the disks' spatial structures at mid- to far-infrared wavelengths. These high spatial resolution images provide unprecedented new constraints on the the dust properties in the systems and limits on the origin of dusty debris. Support for this work was provided by NASA through Contract Number 960785 issued by JPL/Caltech.

This paper analyses research on the impact of work on mothers' health in Tehran (Iran) within a role analytic framework. A survey was conducted of a representative sample of working and non-working mothers in Tehran in 1998 (N = 1065, 710 working mothers, and 355 non-working mothers). Three main explanatory factors were examined (socio-demographic, work and work-related, and social-life context variables) alongside a range of mental and physical health outcome variables. Unlike in the West, where women's paid work is generally associated with better health, statistically significant differences between working and non-working women were not found in Tehran. It is argued that this is a result of the counter-balance of the positive and negative factors associated with paid work, such as increased stress on one hand and self-esteem on the other. Iranian society's particular socio-cultural climate has contributed to this finding, with its dominant gender-role ideology; the priority and extra weight placed on women's traditional roles as wives and mothers, and the remarkably influential impact of husbands' attitudes on women's health.

Work right to right work: An automythology of chronic illness and work.

Vijayasingham, Lavanya

Objectives Chronic illness is known to disrupt and redirect the usual course of work trajectories. This article aims to portray the longitudinal course of negotiating work after multiple sclerosis. Methods Using therapy and personal journals to reconstruct memories and experience, an autoethnography is produced and narrated within Campbell's "Hero's Journey" automythology framework. Results The narrative highlights the intrasubjectivity of illness meaning-the changing internal meaning-making and external behavior and decision-making dynamics. The journey of being inhibited to "Work Right", to "Looking for the Right" and ultimately, finding "Right Work" is charted; portrayed as a bittersweet maneuver to achieve work-illness equilibrium. Discussion This journey traverses a spectrum of negative coping-the exhibition of deviant work behaviors, disengagement and depression; to recalibration and renewal; culminating in living the "new normal", and finding moral and meaningful work engagements. Life trajectories with chronic illness are often skewed and redirected; but longitudinal narratives of normalization and coping also highlight the pursuits to secure and maintain a life of meaning and value.

Tummers, Lars G; Den Dulk, Laura

2013-09-01

The aim of this study was to analyse the effects of work alienation on organisational commitment, work effort and work-to-family enrichment. There is substantial research on the effects of work alienation on passive job performance, such as organisational commitment. However, studies analysing work alienation on active performance, such as work effort, and outside work, such as work-to-family enrichment, are scarce. Two dimensions of work alienation are considered: powerlessness and meaninglessness. Hypotheses are tested using surveys collected among a national sample of midwives in the Netherlands (respondents: 790, response rate 61%). the findings indicate that work alienation (powerlessness and meaninglessness) influence organisational commitment, work effort and--to a lesser extent--work-to-family enrichment. High work meaninglessness, in particular, has negative effects on these outcomes. When people feel that they have no influence in their work (hence, when they feel 'powerless') and especially when the feel that their work is not worthwhile (when they feel 'meaningless') this has substantial negative effects. Managers should increase the meaningfulness that people attach to their work, thereby maintaining a high-quality workforce. Possible strategies include: (1) improving person-job fit, (2) developing high-quality relationships, (3) better communicating the results people help to deliver. © 2013 John Wiley & Sons Ltd.

The present work reviews the history of Io studies and describes the current level of understanding of Io's physics, chemistry, geology, orbital dynamics, and geophysics. Consideration is given to the satellite's internal, superficial, atmospheric, plasma, and magnetospheric properties and how they interrelate. A pictorial map of Io's surface based on Voyager 1 and 2 images is presented. It is found that Io's surface color and spectra are dominated by sulfur compounds which may include various sulfur allotropes. Volcanic processes yielding three kinds of surface features (vent regions, plains, and mountains) dominate Io's surface geology. The Io plasma torus corotates with Jupiter's magnetic field in the plane of Jupiter's centrifugal equator centered at Io's orbital radius

Workplace spirituality, work engagement and thriving at work

Directory of Open Access Journals (Sweden)

Freda van der Walt

2018-01-01

Full Text Available Orientation: In order to create competitive advantage in an increasingly turbulent economic environment, sustainability of high performance is crucial. Only a few individuals have the drive, mindset, discipline and ability to sustain high performance on a daily basis. Thus, it is necessary to consider what can be done so that employees can sustain high performance over the long term. Research purpose: The purpose of the study was to establish whether spiritual workplaces will enhance employees’ work engagement and thriving at work. Motivation for the study: Two important mechanisms for understanding the human dimension of sustainability are thriving at work and work engagement. However, because work engagement and thriving are affective-motivational states, it is necessary to consider contextual factors that promote these positive states. As work engagement and thriving at work move beyond mere energy, to a sense of connectedness, it seems important that spiritual workplaces are created. Research approach, design and method: The study was quantitative in nature, and data were collected from employees working at small, medium and macro enterprises (SMMEs in one geographical area in South Africa. The final sample consisted of 259 employees. A survey that was cross-sectional in nature was conducted by means of a self-administered questionnaire. Main findings: The findings of the study show that there is a positive and significant relationship between workplace spirituality, work engagement and thriving at work. Furthermore, workplace spirituality significantly influences the variance in both work engagement and thriving at work. Practical or managerial implications: In order for SMMEs to promote work engagement and thriving at work, spiritual workplaces need to be created. Furthermore, emphasis needs to be placed on the work experience, rather than on work outcomes. It is also important that SMMEs develop employees holistically, that they create

Is working memory still working?

Science.gov (United States)

Baddeley, A D

2001-11-01

The current state of A. D. Baddeley and G. J. Hitch's (1974) multicomponent working memory model is reviewed. The phonological and visuospatial subsystems have been extensively investigated, leading both to challenges over interpretation of individual phenomena and to more detailed attempts to model the processes underlying the subsystems. Analysis of the controlling central executive has proved more challenging, leading to a proposed clarification in which the executive is assumed to be a limited capacity attentional system, aided by a newly postulated fourth system, the episodic buffer. Current interest focuses most strongly on the link between working memory and long-term memory and on the processes allowing the integration of information from the component subsystems. The model has proved valuable in accounting for data from a wide range of participant groups under a rich array of task conditions. Working memory does still appear to be working.

Schedule control and supervisor support for family and personal life are work resources that may help employees manage the work-family interface. However, existing data and designs have made it difficult to conclusively identify the effects of these work resources. This analysis utilizes a group-randomized trial in which some units in an information technology workplace were randomly assigned to participate in an initiative, called STAR, that targeted work practices, interactions, and expectations by (a) training supervisors on the value of demonstrating support for employees' personal lives and (b) prompting employees to reconsider when and where they work. We find statistically significant, though modest, improvements in employees' work-family conflict and family time adequacy and larger changes in schedule control and supervisor support for family and personal life. We find no evidence that this intervention increased work hours or perceived job demands, as might have happened with increased permeability of work across time and space. Subgroup analyses suggest the intervention brings greater benefits to employees more vulnerable to work-family conflict. This study advances our understanding of the impact of social structures on individual lives by investigating deliberate organizational changes and their effects on work resources and the work-family interface with a rigorous design.

[Investigating work, age, health and work participation in the ageing work force in Germany].

Ebener, M; Hasselhorn, H M

2015-04-01

Working life in Germany is changing. The work force is ageing and the number of people available to the labour market will - from now on - shrink considerably. Prospectively, people will have to work longer; but still today, most people leave employment long before reaching official retirement age. What are the reasons for this? In this report, a conceptual framework and the German lidA Cohort Study are presented. The "lidA conceptual framework on work, age, health and work participation" visualises determinants of employment (11 "domains") in higher working age, e. g., "work", "health", "social status" and "life style". The framework reveals 4 key characteristics of withdrawal from work: leaving working life is the result of an interplay of different domains (complexity); (early) retirement is a process with in part early determinants in the life course (processual character); retirement has a strong individual component (individuality); retirement is embedded in a strong structural frame (structure). On the basis of this framework, the "lidA Cohort Study on work, age, health and work participation" (www.lida-studie.de) investigates long-term effects of work on health and work participation in the ageing work force in Germany. It is the only large study in Germany operationalising the concept of employability in a broad interdisciplinary approach. Employees subject to social security and born in 1959 or in 1965 will be interviewed (CAPI) every 3 years (N[wave 1]=6 585, N[wave 2]=4 244) and their data will be linked (where consented) with social security data covering employment history and with health insurance data. The study design ("Schaie's most efficient design") allows for a tri-factor model that isolates the impact of age, cohort and time. In 2014, the second wave was completed. In the coming years lidA will analyse the association of work, health and work participation, and identify age as well as generation differences. lidA will investigate the

Perceptual effects on remembering: recollective processes in picture recognition memory.

Science.gov (United States)

Rajaram, S

1996-03-01

In 3 experiments, the effects of perceptual manipulations on recollective experience were tested. In Experiment 1, a picture-superiority effect was obtained for overall recognition and Remember judgements in a picture recognition task. In Experiment 2, size changes of pictorial stimuli across study and test reduced recognition memory and Remember judgements. In Experiment 3, deleterious effects of changes in left-right orientation of pictorial stimuli across study and test were obtained for Remember judgements. An alternate framework that emphasizes a distinctiveness-fluency processing distinction is proposed to account for these findings because they cannot easily be accommodated within the existing account of differences in conceptual and perceptual processing for the 2 categories of recollective experience: Remembering and Knowing, respectively (J. M. Gardiner, 1988; S. Rajaram, 1993).

Perceptual Organization of Shape, Color, Shade, and Lighting in Visual and Pictorial Objects

Full Text Available The main questions we asked in this work are the following: Where are representations of shape, color, depth, and lighting mostly located? Does their formation take time to develop? How do they contribute to determining and defining a visual object, and how do they differ? How do visual artists use them to create objects and scenes? Is the way artists use them related to the way we perceive them? To answer these questions, we studied the microgenetic development of the object perception and formation. Our hypothesis is that the main object properties are extracted in sequential order and in the same order that these roles are also used by artists and children of different age to paint objects. The results supported the microgenesis of object formation according to the following sequence: contours, color, shading, and lighting.

To assess factors associated with professional and total hours of work (work + home) among nursing staff. Cross-sectional study conducted in a university hospital in the city of São Paulo, southeastern Brazil, between 2004 and 2005. A total of 696 workers (nurses, nurse technicians and aids), mostly women (87.8%) working day and/or night shifts, participated in the study. A self-administered questionnaire was used to collected information on demographic characteristics, and working and life conditions. Translated and adapted into Portuguese versions of the Job Stress Scale, Effort-reward imbalance, Short-Form-Health-related quality of life and the Work Ability Index were also administered. Logistic regression models were used for data analysis. Sole breadwinner, working night shifts and effort-reward imbalance were the variables associated with both professional (OR = 3.38, OR = 10.43, OR = 2.07, respectively) and total hours of work (OR = 1.57, OR = 3.37, OR = 2.75, respectively). There was no significant association between the variables related to hours of work and low Work Ability Index. Inadequate rest at home was statistically associated with professional (OR = 2.47) and total hours of work (OR = 1.48). Inadequate leisure time was significantly associated with professional hours of work (OR = 1.58) and barely associated with total hours of work (OR = 1.43). The sole breadwinner, working night shifts and effort-reward imbalance are variables that need to be further investigated in studies on work hours among nursing staff. These studies should explore workers' income and the relationship between effort and reward, taking into consideration gender issues.

Little research has explored burnout and its causes in the American fire service. Data were collected from career firefighters in the southeastern United States (n = 208) to explore these relationships. A hierarchical regression model was tested to examine predictors of burnout including sociodemographic characteristics (model 1), work pressure (model 2), work stress and work-family conflict (model 3) and interaction terms (model 4). The main findings suggest that perceived work stress and work-family conflict emerged as the significant predictors of burnout (both p < .001). Interventions and programs aimed at these predictors could potentially curtail burnout among firefighters.

To demonstrate the importance of including a range of working conditions in models exploring the association between health- and work-related performance. The Australian Work Outcomes Research Cost-benefit study cross-sectional screening data set was used to explore health-related absenteeism and work performance losses on a sample of approximately 78,000 working Australians, including available demographic and working condition factors. Data collected using the World Health Organization Health and Productivity Questionnaire were analyzed with negative binomial logistic regression and multinomial logistic regressions for absenteeism and work performance, respectively. Hours expected to work, annual wage, and job insecurity play a vital role in the association between health- and work-related performance for both work attendance and self-reported work performance. Australian working conditions are contributing to both absenteeism and low work performance, regardless of health status.

Work engagement and meaningful work across generational cohorts

Directory of Open Access Journals (Sweden)

Crystal Hoole

2015-08-01

Full Text Available Orientation: Engaging employees and providing employees with a sense of meaning at work is not a one-size-fits-all approach. Although research has shown that differences between work engagement and meaningful work amongst generational cohorts exist, results are still inconclusive. With age becoming increasingly more important as a diversity factor, a better understanding of the dynamics between work engagement and meaningful work across different generational cohorts is necessary to design the right strategy for each organisation’s unique parameters. Research purpose: The aim of this study was to determine whether there is a relationship between work engagement and meaningful work and whether there are significant variances between the levels of work engagement and meaningful work between different generational cohorts. Motivation for study: Work engagement has consistently been highlighted by researchers and human resources experts as a recommended solution to provide companies with the upper hand when it comes to creating a competitive edge. Yet, levels of work engagement are far from ideal, requiring intensified efforts to identify solutions towards raising overall engagement levels. In recent years, much of the focus in terms of generating engagement has been aimed in the direction of financial rewards and other benefits; some organisational experts are of the opinion that a shift is occurring towards meaningful work instead of monetary rewards as the driver of engagement. The changing nature of the work landscape also suggests that generational cohorts experience work engagement and meaningful work differently. Understanding these complexities is mandatory in creating solutions towards improving levels of engagement and meaningful work. Research approach, design and method: A cross-sectional quantitative research approach has been followed. The Utrecht Work Engagement Scale (UWES and Psychological Meaningful Scale (PMS were administered

About 3 to 10% of pregnancies are complicated by glycemic control abnormalities. Maternal diabetes results in significantly greater risk for antenatal, perinatal, and neonatal morbidity and mortality, as well as congenital malformations. The number of diabetic mothers is expected to rise, as more and more of the obese pediatric female population in developed and some developing countries progresses to childbearing age. Radiologists, being part of the teams managing such pregnancies, should be well aware of the findings that may be encountered in infants of diabetic mothers. Timely, accurate, and proper radiological evaluation can reduce morbidity and mortality in these infants. The purpose of this essay is to illustrate the imaging findings in the various pathological conditions involving the major body systems in the offspring of women with diabetes

The skull base anatomy is complex. Numerous vital neurovascular structures pass through multiple channels and foramina located in the base skull. With the advent of computerized tomography (CT) and magnetic resonance imaging (MRI), accurate preoperative lesion localization and evaluation of its relationship with adjacent neurovascular structures is possible. It is imperative that the radiologist and skull base surgeons are familiar with this complex anatomy for localizing the skull base lesion, reaching appropriate differential diagnosis, and deciding the optimal surgical approach. CT and MRI are complementary to each other and are often used together for the demonstration of the full disease extent. This article focuses on the radiological anatomy of the skull base and discusses few of the common pathologies affecting the skull base

Focal lesions in bone are very common and many of these lesions are not bone tumors. These bone tumor mimickers can include numerous normal anatomic variants and non-neoplastic processes. Many of these tumor mimickers can be left alone, while others can be due to a significant disease process. It is important for the radiologist and clinician to be aware of these bone tumor mimickers and understand the characteristic features which allow discrimination between them and true neoplasms in order to avoid unnecessary additional workup. Knowing which lesions to leave alone or which ones require workup can prevent misdiagnosis and reduce patient anxiety

One of the major problems radiologists face in everyday practice is to decide the correct diagnosis, or at least narrow down the list of possibilities. In this context, indicative evidences (signs) are useful to recognize pathologies, and also to narrow the list of differential diagnoses. Despite classically being described for a single disease, or a closely related family of disorders, most indications are not restricted exclusively to their traditional definition. Therefore, using signs for prognosis requires knowledge of the mechanism of their appearance, and which pathologies they are observed in. In this study, we demonstrate some of the more common and useful neuroradiologic signs with relevant images, and discuss their use in differential diagnosis.

Tennis leg is caused by a rupture of the medial head of the gastrocnemius muscle, usually at its distal musculotendinous junction region. However, tears in this muscle and its tendon are also included under the term 'tennis leg'. It is seen regularly in practice and is an important cause of a painful calf. The common USG findings include: disruption of the pinnate pattern of the distal medial gastrocnemius, usually near the junction of the triceps surae (which is the echogenic line between the gastrocnemius, the soleus, and the plantaris muscles), fluid tracking along the fascia, adjacent hematoma, and intramuscular tears as well as hematomas. USG is useful for confirming the diagnosis, excluding other causes of a painful calf, for assessing the severity of the disease, and in follow-up.

The ability of 7-, 8-, and 9-year-olds to understand proverbs was examined by having subjects compare each proverb against two thematic pictures: a nonliteral correct interpretation of the proverb and a foil. The results, which contradict the literature, showed consistent above-chance performance across subjects, ages, and proverbs. (Author/JMB)

Organizations have started to redesign their approach to work by integrating technological innovations in their daily practices. Central to this new approach is that employees are asked to organize their work flexibly. Employees are expected to decide for themselves when they work, where they work,

A review of the literature determined that our understanding of the efficacy of flexible work arrangements (FWA) in reducing work-family conflict remains inconclusive. To shed light on this issue by examining the relationship between work-to-family conflict, in which work interferes with family (WFC), family-to-work conflict, in which family interferes with work (FWC), and four work arrangements: the traditional 9-5 schedule, compressed work weeks (CWWs) flextime, and telework. Hypotheses were tested on a sample of 16,145 employees with dependent care responsibilities. MANCOVA analysis was used with work arrangement as the independent variable and work interferes with family (WFC) and family interferes with work (FWC) as dependent variables. Work demands, non-work demands, income, job type and gender were entered into the analysis as covariates. The more flexible work arrangements such as flextime and telework were associated with higher levels of WFC than were fixed 9-to 5 and CWW schedules. Employees who teleworked reported higher FWC than their counterparts working a traditional 9-to-5 schedule particularly when work demands were high. The removal of both temporal and physical boundaries separating work and family domains results in higher levels of work-family interference in both directions. The results from this study suggest that policy makers and practitioners who are interested in improving employee well-being can reduce work-family conflict, and by extension improve employee mental health, by focusing on the effective use of traditional and CWW schedules rather than by implementing flextime and telework arrangements.

Identity at work: Exploring strategies for Identity Work

2012-09-01

Research purpose: The main aim of this study was to explore employee narratives and identify the strategies available to them in the process of identity work, as they defined themselves at work. Motivation for the study: As there is a scarcity of research on identity work in South Africa, this study wanted to advance knowledge about identity work and the strategies used for regulating and negotiating an identity at work by exploring these constructs in this context. Research design, approach and method: A qualitative research process formed the basis for this study. Nineteen employees from a global manufacturing company participated in two semi-structured in-depth interviews. Grounded theory was applied to analyse and interpret the data. Main findings: Nine strategies for identity work were identified and categorised into four broad themes (personal philosophies; relationships; career management and negotiating balance. Practical/managerial implications: Employees followed various strategies for defining themselves at work and this may have some implications for employee work engagement and productivity. Contribution/value-add: This study expands on current theoretical knowledge of identity work, and provides insights into the strategies people use to regulate and negotiate their identities at work.

Despite public concern about time pressures experienced by working parents, few scholars have explicitly examined the effects of work time on work-family conflict. The authors developed and tested a model of the predictors of work time and the relationships between time, work interference with family (WIF). and psychological distress. Survey data came from 513 employees in a Fortune 500 company. As predicted, several work and family characteristics were significantly related to work time. In addition, work time was significantly, positively related to WIF, which in turn was significantly, negatively related to distress. The results suggest that work time fully or partially mediates the effects of many work and family characteristics on WIF.

In this study, we examine the role of work hours in a model that incorporates involvement in both work and family with experiences of work-family conflict and subjective well-being. Self-report data were collected from 383 full-time employees and analysed using structural equation modelling techniques. Results demonstrate that role salience was positively related to behavioural involvement with work and with family. In turn, behavioural family involvement was negatively related to work hours and family-to-work conflict, while behavioural work involvement was positively related to work hours. Behavioural family involvement was also positively related to life satisfaction. Finally, both family-to-work conflict and end-of-workday strain were negatively related to life satisfaction. Our results provide insight into unexpected problems that might arise when employees place overly high importance on work and work long hours. This study serves as a foundation for researchers to examine the interplay of time spent with work and family with other aspects of the work-family interface.

2008-06-01

Full Text Available Abstract Background There is uncertainty about how GPs should convey information about treatment effectiveness to their patients in the context of cardiovascular disease. Hence we study the concordance of decisions based on one of four single information formats for treatment effectiveness with subsequent decisions based on all four formats combined with a pictorial representation. Methods A randomized study comprising 1,169 subjects aged 40–59 in Odense, Denmark. Subjects were randomized to receive information in terms of absolute risk reduction (ARR, relative risk reduction (RRR, number needed to treat (NNT, or prolongation of life (POL without heart attack, and were asked whether they would consent to treatment. Subsequently the same information was conveyed with all four formats jointly accompanied by a pictorial presentation of treatment effectiveness. Again, subjects should consider consent to treatment. Results After being informed about all four formats, 52%–79% of the respondents consented to treatment, depending on level of effectiveness and initial information format. Overall, ARR gave highest concordance, 94% (95% confidence interval (91%; 97% between initial and final decision, but ARR was not statistically superior to the other formats. Conclusion Decisions based on ARR had the best concordance with decisions based on all four formats and pictorial representation, but the difference in concordance between the four formats was small, and it is unclear whether respondents fully understood the information they received.

Adolescents' perceptions of cigarette brand image: does plain packaging make a difference?

To examine the effect of plain packaging on adolescents' perceptions of cigarette packs, attributes of smokers, and expectations of cigarette taste, and to identify the effect of increasing the size of pictorial health warnings on appraisal of plain packs. We used a 5 (degree of plain packaging and graphic health warning)x 3 (brand type) between-subjects experimental design, using a Web-based methodology to expose adolescents to one randomly selected cigarette pack, during which respondents completed ratings. When brand elements such as color, branded fonts, and imagery were progressively removed from cigarette packs, adolescents perceived packs to be less appealing, rated attributes of a typical smoker of the pack less positively, and had more negative expectations of cigarette taste. Pack appeal was reduced even further when the size of the pictorial health warning on the most plain pack was increased from 30% to 80% of the pack face, with this effect apparent among susceptible nonsmokers, experimenters, and established smokers. Removing as much brand information from cigarette packs as possible is likely to reduce positive cigarette brand image associations among adolescents. By additionally increasing the size of pictorial health warnings, positive pack perceptions of those who are at greater risk of becoming regular addicted adult smokers are most likely to be reduced.

Research with the evaluative priming paradigm has shown that affective evaluation processes reliably influence cognition and behavior, even when triggered outside awareness. However, the precise mechanisms underlying such subliminal evaluative priming effects, response activation vs semantic processing, are matter of a debate. In this study, we determined the relative contribution of semantic processing and response activation to masked evaluative priming with pictures and words. To this end, we investigated the modulation of masked pictorial vs verbal priming by previously activated perceptual vs semantic task sets and assessed the electrophysiological correlates of priming using event-related potential (ERP) recordings. Behavioral and electrophysiological effects showed a differential modulation of pictorial and verbal subliminal priming by previously activated task sets: Pictorial priming was only observed during the perceptual but not during the semantic task set. Verbal priming, in contrast, was found when either task set was activated. Furthermore, only verbal priming was associated with a modulation of the N400 ERP component, an index of semantic processing, whereas a priming-related modulation of earlier ERPs, indexing visuo-motor S-R activation, was found for both picture and words. The results thus demonstrate that different neuro-cognitive processes contribute to unconscious evaluative priming depending on the stimulus format. © The Author (2016).

Work limitation rates are crucial indicators of the health status of working people. If related to work productivity, work limitation rates may also supply important information about the economic burden of illness. Our objective was to assess the productivity impact of on-the-job work limitations due to employees' physical or mental health problems. Subjects were asked to complete a self-administered survey on the job during 3 consecutive months. Using robust regression analysis, we tested the relationship of objectively-measured work productivity to employee-reported work limitations. We attempted to survey employees of a large firm within 3 different jobs. The survey response rate was 2245 (85.9%). Full survey and productivity data were available for 1827 respondents. Each survey included a validated self-report instrument, the Work Limitations Questionnaire (WLQ). The firm provided objective, employee-level work productivity data. In adjusted regression analyses (n = 1827), employee work productivity (measured as the log of units produced/hour) was significantly associated with 3 dimensions of work limitations: limitations handling the job's time and scheduling demands (P = 0.003), physical job demands (P = 0.001), and output demands (P = 0.006). For every 10% increase in on-the-job work limitations reported on each of the 3 WLQ scales, work productivity declined approximately 4 to 5%. Employee work limitations have a negative impact on work productivity. Employee assessments of their work limitations supply important proxies for the economic burden of health problems.

Making residency work hour rules work.

Cohen, I Glenn; Czeisler, Charles A; Landrigan, Christopher P

2013-01-01

In July 2011, the ACGME implemented new rules that limit interns to 16 hours of work in a row, but continue to allow 2nd-year and higher resident physicians to work for up to 28 consecutive hours. Whether the ACGME's 2011 work hour limits went too far or did not go far enough has been hotly debated. In this article, we do not seek to re-open the debate about whether these standards get matters exactly right. Instead, we wish to address the issue of effective enforcement. That is, now that new work hour limits have been established, and given that the ACGME has been unable to enforce work hour limits effectively on its own, what is the best way to make sure the new limits are followed in order to reduce harm to residents, patients, and others due to sleep-deprived residents? We focus on three possible national approaches to the problem, one rooted in funding, one rooted in disclosure, and one rooted in tort law. © 2013 American Society of Law, Medicine & Ethics, Inc.

Exoplanet Caught on the Move

Science.gov (United States)

2010-06-01

For the first time, astronomers have been able to directly follow the motion of an exoplanet as it moves from one side of its host star to the other. The planet has the smallest orbit so far of all directly imaged exoplanets, lying almost as close to its parent star as Saturn is to the Sun. Scientists believe that it may have formed in a similar way to the giant planets in the Solar System. Because the star is so young, this discovery proves that gas giant planets can form within discs in only a few million years, a short time in cosmic terms. Only 12 million years old, or less than three-thousandths of the age of the Sun, Beta Pictoris is 75% more massive than our parent star. It is located about 60 light-years away towards the constellation of Pictor (the Painter) and is one of the best-known examples of a star surrounded by a dusty debris disc [1]. Earlier observations showed a warp of the disc, a secondary inclined disc and comets falling onto the star. "Those were indirect, but tell-tale signs that strongly suggested the presence of a massive planet, and our new observations now definitively prove this," says team leader Anne-Marie Lagrange. "Because the star is so young, our results prove that giant planets can form in discs in time-spans as short as a few million years." Recent observations have shown that discs around young stars disperse within a few million years, and that giant planet formation must occur faster than previously thought. Beta Pictoris is now clear proof that this is indeed possible. The team used the NAOS-CONICA instrument (or NACO [2]), mounted on one of the 8.2-metre Unit Telescopes of ESO's Very Large Telescope (VLT), to study the immediate surroundings of Beta Pictoris in 2003, 2008 and 2009. In 2003 a faint source inside the disc was seen (eso0842), but it was not possible to exclude the remote possibility that it was a background star. In new images taken in 2008 and spring 2009 the source had disappeared! The most recent

Previous research has revealed that work-family conflict negatively influences women's health following childbirth. To examine if flexible work arrangements were associated with work-family conflict among women, 1 year after childbirth. Employed women, aged >or=18, were recruited while hospitalized for childbirth. Flexible work arrangements were measured at 6 months and work-family conflict was measured at 12 months. General linear models estimated the association between flexible work arrangements and work-family conflict. Of 1157 eligible participants, 522 were included in this analysis giving a 45% response rate. Compared to women who reported that taking time off was very hard, those who reported it was not too hard (beta = -0.80, SE = 0.36, P hours was associated with greater home spillover (beta = 0.46, SE = 0.18, P work home was associated with increased home spillover (beta = 0.35, SE = 0.14, P work hours and the ability to take work home were associated with increased home spillover to work. The ability to take time off was associated with decreased job spillover to home. Additional research is needed to examine the intentional and unintentional consequences of flexible work arrangements.

Social Work or Relief Work? A Crisis in Professional Social Work

Directory of Open Access Journals (Sweden)

Adhikari Harasankar

2015-07-01

Full Text Available Social work is a sharing and caring profession based on scientific methods. This problem solving profession makes people self-reliant and self-dependent when he/she is in any sorts of crises. Thus, it differs from relief work, social services or social welfare delivered during emergence crises. This paper examined the application of professional social work as relief work, which did not bring any change among the beneficiaries; rather it set their mind as opportunist. For this purpose, the programme sponsored by the government of India and implemented by nongovernmental organizations for rehabilitation of the street children (i.e., pavements and slums dwellers, children of sex workers, and so forth of Metro cities like Kolkata had priority. This evaluative study assessed the progress and changes among 500 street children who were the beneficiaries for 10 years of the programme, selected according to their parental residents/occupation through stratified sampling. Interviews, case studies and group interaction were used to collect data on various aspects, i.e. personal background, education, and occupation of these children. It revealed that after almost 10 years of services, the problem of children was static. Firstly, service delivery system was as relief work. The methods of social work were not implied while the professionals were in implementation. On the other hand, the scope of monitoring and evaluation of the programme by government was suspended due to several reasons. Definitely, the politicalization in human development would be restricted. The problems of suffering would be root out and it should not be a continued process.

Work-based resources as moderators of the relationship between work hours and satisfaction with work-family balance.

This study reports an investigation of the relationships of work hours, job complexity, and control over work time to satisfaction with work-family balance. Based on data from a sample of 570 telephone call center representatives, a moderated hierarchical regression analysis revealed that work hours were negatively related to satisfaction with work-family balance, consistent with the resource drain perspective. Job complexity and control over work time were positively associated with satisfaction with work-family balance. Control over work time moderated the relationship such that as work hours rose, workers with low control experienced a decline in work-family balance satisfaction, while workers with high control did not. Results encourage greater research attention to work characteristics, such as job complexity and control over work time, and skills that represent resources useful to the successful integration of work and family demands.

Nurses' work demands and work-family conflict: a questionnaire survey.

Science.gov (United States)

Yildirim, Dilek; Aycan, Zeynep

2008-09-01

Work-family conflict is a type of interrole conflict that occurs as a result of incompatible role pressures from the work and family domains. Work role characteristics that are associated with work demands refer to pressures arising from excessive workload and time pressures. Literature suggests that work demands such as number of hours worked, workload, shift work are positively associated with work-family conflict, which, in turn is related to poor mental health and negative organizational attitudes. The role of social support has been an issue of debate in the literature. This study examined social support both as a moderator and a main effect in the relationship among work demands, work-to-family conflict, and satisfaction with job and life. This study examined the extent to which work demands (i.e., work overload, irregular work schedules, long hours of work, and overtime work) were related to work-to-family conflict as well as life and job satisfaction of nurses in Turkey. The role of supervisory support in the relationship among work demands, work-to-family conflict, and satisfaction with job and life was also investigated. The sample was comprised of 243 participants: 106 academic nurses (43.6%) and 137 clinical nurses (56.4%). All of the respondents were female. The research instrument was a questionnaire comprising nine parts. The variables were measured under four categories: work demands, work support (i.e., supervisory support), work-to-family conflict and its outcomes (i.e., life and job satisfaction). The structural equation modeling results showed that work overload and irregular work schedules were the significant predictors of work-to-family conflict and that work-to-family conflict was associated with lower job and life satisfaction. Moderated multiple regression analyses showed that social support from the supervisor did not moderate the relationships among work demands, work-to-family conflict, and satisfaction with job and life.

To investigate factors associated with work ability among nursing professionals. They comprised 514 nursing professionals (83.8% of the total number of workers) from a hospital in São Paulo, Brazil. In 2009, we conducted a cross-sectional study that was a part of a 5-year planned cohort study initiated in 2008. We administered a comprehensive questionnaire to the participants in order to obtain data on their sociodemographic characteristics, lifestyles, and working conditions. The questionnaire also contained the Brazilian versions of the following: the Job Stress Scale (JSS), Effort-Reward Imbalance (ERI) Questionnaire, Work-Related Activities That May Contribute To Job-Related Pain and/or Injury (WRAPI), and Work Ability Index (WAI). The results were analyzed using descriptive, bivariate, and multivariate linear regression analyses. On the WAI, 74.9% of the workers obtained a score of over 40 points (score range 7-49); the mean score was 42.3 points (SD=4.5). The final multivariate model showed that lower WAI scores were related to the work-related outcome, which was work injury, and the following individual characteristics and working conditions: body mass index (p=0.001), sex (female; p=0.002), sedentariness (p work (p=0.003), effort-reward ratio (p=0.001), violence at work (p=0.005), WRAPI score (p work injuries (yes; p=0.001). Various factors were associated with work ability. The results showed that a number of variables should be considered when planning and implementing actions to maintain or improve work ability among nursing professionals.

Franzén, Cecilia

2012-08-01

The Swedish policy objectives in dental care provision - to meet public demands for dental care and to increase the cost-effectiveness of the service - require dentists to work in teams with dental hygienists and dental nurses. This study focused on the role of dentists in the distribution of work tasks within teams in one Swedish Public Dental Service organisation. Dental clinics were viewed as micro-political arenas in which dentists attempt to demarcate professional boundaries in response to teamwork. Semi-structured interviews, observations and documents were used. The interviewed individuals were seven dentists employed at two clinics, the managers of each clinic and the general manager. The dentists were interviewed to investigate how they defend or blur professional boundaries. They were also observed at work. The clinic managers and the general manager were interviewed to identify their expectations of dentists concerning work division. The documents comprised organisational plans and annual reports. Dentists demarcated professional boundaries by utilising various power resources: treatment responsibility, specialist knowledge, discretion, and avoidance of work considered to be low status work. The dentists also contributed to blurred boundaries between themselves and the other dental professionals by discussing patient treatment, giving and receiving advice, and assisting the others in skill development. Although dentists' boundary work could obstruct implementation of policy objectives, dentists' behaviour contributed to effective collaboration within the teams. © 2012 John Wiley & Sons A/S.

Cugtun Alngautat: the history and development of a picture text among the Nuniwarmiut Eskimo, Nunivak Island, Alaska.

Griffin, Dennis G

2010-01-01

Native Americans have long relied on the oral transmission of their ideas rather than developing an alphabet and a reliance on written records. While the use of pictures to communicate basic concepts is found throughout Alaska during the historic contact period, the development of an alphabet or pictorial text among Natives in Alaska is extremely limited with examples found only in the Kuskokwim Delta (ca. 1901) and Seward Peninsula (ca. 1914). The later appearance of a pictorial text on Nunivak Island (ca. 1940) is believed to have derived from the Seward Peninsula style. Each of these texts is believed to have originated from the influence of missionaries. This paper traces the appearance and development of a picture text among the Nuniwarmiut Eskimo on Nunivak Island and its current status in the Mekoryuk community.

Cognitive bias, such as selective memory for pain-related information, is frequently observed in chronic pain patients and is assessed mostly using verbal material. Beside word lists, the current study used photographs of people presenting pain behaviors to assess memory bias in chronic pain patients. Chronic pain patients were hypothesized to show better recall of pain-related words and pictures as compared to pain-free controls. Twenty-eight female chronic neck patients and 28 pain-free female controls completed two computerized pictorial memory games and two word recall tasks. Patients and controls performed equally well in the neutral pictorial memory game. In the pain-related game, patients performed significantly worse than controls. No significant differences were found in the word recall task. The result is discussed in terms of cognitive avoidance.

2008-01-01

To evaluate work satisfaction among Spanish nurses employed by English hospitals, as well as the influence of several social and work-related variables associated with satisfaction. We performed a cross-sectional study. All Spanish nurses (n=360) with a contract with any English hospital in April 2003 were included in the study. The self-administered and validated Font Roja work satisfaction questionnaire was used. The response rate was 78.6%. Overall work satisfaction among Spanish nurses was medium. The dimensions with higher work satisfaction were relationships with colleagues and superiors. The dimensions showing lowest work satisfaction were job satisfaction and professional competence. Statistically significant and positive associations were obtained between level of English, professional grade, shift pattern, working in the intensive care unit or accident and emergency department, time worked in English hospitals and degree of work satisfaction. Employers of Spanish nurses should try to increase job satisfaction and professional competence among these workers. Incentivation and professional promotion systems might help achieve this aim. Employers could also try to improve Spanish nurses' English level before contracts are signed and pay special attention to their needs during the first working year. Spanish nurses job satisfaction would also increase if they were allowed to choose their working shift and the unit or ward where they are going to work.
