  1. Croatian "Judiths"

    Directory of Open Access Journals (Sweden)

    Teodora Vigato

    2016-02-01

    Full Text Available In this paper, the authors deal with various interpretations in Croatian literature of the biblical Judith and Marulić’s Judith. They begin with the story of Judith from Zadar whose anonymous authors had the task to spread the biblical story of the courageous Judith. Then they speak about Judith in the works of Antun Gleđević and Ignjat Đurđević, in the Baroque literature of Dubrovnik, in the context of the Dubrovnik melodramatic or pseudolibretistic production. The paper highlights the Slavonian Judith, that is, her interludes and concludes with the contemporary Judiths of Miro Gavran and Boris Senker. The biblical text has served also as an inspiration for various interpretations in a wide range of performances, from musical to puppet theatre. Each author followed the point of view, the artistically specific, poetic, structural and technical requirements of the genre and placed the main character and her story in a new intertextual or media content.

  3. Mason & Dixon and Hamlet

    2014-08-01

    Full Text Available Although there is no explicit comparison in 'Mason & Dixon' of the astronomer protagonist Charles Mason to the eponymous hero of Shakespeare's masterpiece, indisputable references to the play are to be found in the novel. Mason is endowed with qualities which mirror Hamlet's virtues and vices: he is a leader and a man of education and wit, though his metaphysical longings entice him towards madness and suicide. He is emburdened with a  deep melancholy stemming from bereavement, loss of love, the hauntings of a ghost, indecision, even cowardice and frustrated ambition.

  5. Dixon's extended bodies and weak gravitational waves

    CERN Document Server

    Bini, Donato; Geralico, Andrea; Ortolan, Antonello

    2009-01-01

    General relativity considers Dixon's theory as the standard theory to deal with the motion of extended bodies in a given gravitational background. We discuss here the features of the "reaction" of an extended body to the passage of a weak gravitational wave. We find that the body acquires a dipolar moment induced by its quadrupole structure. Furthermore, we derive the "world function" for the weak field limit of a gravitational wave background and use it to estimate the deviation between geodesics and the world lines of structured bodies. Measuring such deviations, due to the existence of cumulative effects, should be favorite with respect to measuring the amplitude of the gravitational wave itself.

    Deriglazov, Alexei A

    2015-01-01

    We obtain Mathisson-Papapetrou-Tulczyjew-Dixon equations of a rotating body with given values of spin and momentum starting from Lagrangian action without auxiliary variables. MPTD-equations correspond to minimal interaction of our spinning particle with gravity. We shortly discuss some novel properties deduced from the Lagrangian form of MPTD-equations: emergence of an effective metric instead of the original one, non-commutativity of coordinates of representative point of the body, spin corrections to Newton potential due to the effective metric as well as spin corrections to the expression for integrals of motion of a given isometry.

    2012-12-01

    Full Text Available Dieser Beitrag widmet sich der Frage, inwiefern Cyber-Mobbing unter Bezugnahme auf Judith Butlers sprach- bzw. diskurstheoretisches Konzept als verletzender Sprechakt verstanden werden kann. Zu diesem Zweck werden in einem ersten Schritt die Besonderheiten von Cyber-Mobbing aufgezeigt und im Anschluss daran ein für diesen Text geeigneter Cyber-Mobbing-Begriff formuliert. Daraufhin erfolgt eine interpretative Auseinandersetzung mit der Butlerschen Konzeption verletzender Sprechakte, bevor anschließend anhand wesentlicher Schnittstellen herausgearbeitet wird, inwiefern Cyber-Mobbing als ein solcher verletzender sprachlicher Akt begriffen werden kann. Resümierend werden die zentralen Ergebnisse der Ausarbeitung zusammengefasst und es wird danach gefragt, welche Konsequenzen bzw. Folgen sich hieraus für ein mögliches verändertes Verständnis von Cyber-Mobbing ergeben.This Paper argues whether cyber bullying can be understood as violating speach act with reference to Judith Butler by starting with a definition of cyber bullying (respectively the term cyber 'mobbing' which is used synonymously in German speaking countries and an outline of Butler's theory. After that, the question of a new or different understanding of cyber bullying and its consequences is discussed.

  17. What makes men and women identify with Judith? A Jungian mythological perspective on the feminist value of Judith today

    Directory of Open Access Journals (Sweden)

    Helen Efthimiadis-Keith

    2012-08-01

    Full Text Available Inspired by her student’s overwhelmingly positive interpretation of Judith as a model for women’s liberation in diverse African contexts – despite the debate around the feminist value of Judith-Judith – the author deals with what could possibly allow men and women, particularly the latter, to interpret Judith positively today. Given her interest in Jungian individuation theory and Ancient Near Eastern (ANE mythology, the author investigates the subject matter by exploring Judith’s relation to male and female individuation patterns, the myths of the hero’s quest and Demeter-Kore, and ANE warrior-goddess myths.

  2. Goiter in portraits of Judith the Jewish heroine.

    Science.gov (United States)

    Lazzeri, Davide; Castello, Manuel Francisco; Lippi, Donatella; Weisz, George M

    2016-01-01

    Judith was a legendary Hebrew heroine who beheaded the general Holofernes and saved the children of Israel from destruction by the Assyrian army. In the Book of Judith, which is still present in the Catholic and Orthodox Christian Bibles, Judith is presented as an illustrious woman who defeated the enemy using her virtue and fortitude. The present investigation has revealed 24 portraits in which Judith has been depicted with variable grades of thyroid gland enlargement on the scene where she decapitates Holofernes. There is no doubt that the integration of a slight thyroid enlargement in the paintings is a stylistic hallmark that portrays an idealized female beauty with a balanced neck and graceful body. The large extended goiter was probably depicted by the artists as a symbol of a powerful masculine body and her courage, and at the same time, it probably also reflects better anatomic accuracy and knowledge of artists from that period.

    Directory of Open Access Journals (Sweden)

    Risimati Synod Hobyane

    2016-04-01

    Full Text Available Narratives are never meant to be neutral in their rhetorical intent. They have power not onlyto reveal realities and prevail worldviews but also to create new realities and new worldviewsby refuting illusions and falsehood, and affirming the truth. The Judith narrative is a goodexample for the exploration of this claim. This article contributes by employing the thematiclevel of analysis, the veridictory square in particular, of the Greimassian approach to narratives,to map out the possible illusions and affirming the truth within the second temple Judaism.The study of the veridictory square as informed by the level of analysis, mentioned above,seems to persuade the reader by first, extracting the truth from illusion and thereafter exposingand shaming falsehood in Judith. Subsequently, the article asserts that Judith is not neutral in itsintent but was designed to deal with illusive ideas that might have been impacting the wellbeingof the second temple Judaism.

    International audience; Dixon's famous theorem states that the group generated by two random permutations of a finite set is generically either the whole symmetric group or the alternating group. In the context of random generation of finite groups this means that it is hopeless to wish for a uniform distribution – or even a non-trivial one – by drawing random permutations and looking at the generated group. Mealy automata are a powerful tool to generate groups, including all finite groups an...

    Full Text Available This paper presents some general guidelines on the distinction sex/gender and its impact on the delimitation of the body category in feminist theory. Then, it offers some arguments that question the sexual dimorphism in natural terms from Judith Butler's psychoanalytic conceptualizations. According to this, essentialist and constructivist approaches are discussed in relation to the body, illustrated from Luce Irigaray and Judith Butler's proposals. Finally, it comes to the conclusion of the need to debate the sex category as a special occasion to reformulate the multiple conceptualizations involving the dimension of the body.

  13. Hydrogeology of the Judith River Formation in southwestern Saskatchewan, Canada

    Science.gov (United States)

    Ferris, David; Lypka, Morgan; Ferguson, Grant

    2017-06-01

    The Judith River Formation forms an important regional aquifer in southwestern Saskatchewan, Canada. This aquifer is used for domestic and agricultural purposes in some areas and supports oil and gas production in other areas. As a result, the available data come from a range of sources and integration is required to provide an overview of aquifer characteristics. Here, data from oil and gas databases are combined with data from groundwater resource assessments. Analysis of cores, drill-stem tests and pumping tests provide a good overview of the physical hydrogeology of the Judith River Aquifer. Water chemistry data from oil and gas databases were less helpful in understanding the chemical hydrogeology due contamination of samples and unreliable laboratory analyses. Analytical modeling of past pumping in the aquifer indicates that decreases in hydraulic head exceeding 2 m are possible over distances of 10s of kilometers. Similar decreases in head should be expected for additional large withdrawals of groundwater from the Judith River Aquifer. Long-term groundwater abstraction should be limited by low pumping rates. Higher pumping rates appear to be possible for short-term uses, such as those required by the oil and gas industry.

    Full Text Available This paper develops a version of Robust Stochastic Maximum Principle (RSMP applied to the Minimax Mayer Problem formulated for stochastic differential equations with the control-dependent diffusion term. The parametric families of first and second order adjoint stochastic processes are introduced to construct the corresponding Hamiltonian formalism. The Hamiltonian function used for the construction of the robust optimal control is shown to be equal to the Lebesque integral over a parametric set of the standard stochastic Hamiltonians corresponding to a fixed value of the uncertain parameter. The paper deals with a cost function given at finite horizon and containing the mathematical expectation of a terminal term. A terminal condition, covered by a vector function, is also considered. The optimal control strategies, adapted for available information, for the wide class of uncertain systems given by an stochastic differential equation with unknown parameters from a given compact set, are constructed. This problem belongs to the class of minimax stochastic optimization problems. The proof is based on the recent results obtained for Minimax Mayer Problem with a finite uncertainty set [14,43-45] as well as on the variation results of [53] derived for Stochastic Maximum Principle for nonlinear stochastic systems under complete information. The corresponding discussion of the obtain results concludes this study.

  16. Ideology and intertextuality: Intertextual allusions in Judith 16

    Directory of Open Access Journals (Sweden)

    S. Philip Nolte

    2011-03-01

    Full Text Available This article utilised the theory of intertextuality to investigate the way in which religious texts, specifically Judith 16, generate meaning in the act of the production of texts. The groundbreaking work on intertextuality done by Julia Kristeva served as the theoretical point of departure. Kristeva utilised Mikhail Bakhtin’s literary theory to develop her own views on intertextuality. According to the theory of intertextuality, all texts are intersections of different texts and are therefore polyvalent. The article argued that the ideology (or ideologies of author(s of texts underpin the ways in which other texts are used and alluded to. The purpose of the investigation was to illustrate how intertextual allusions in Judith 16 are used to describe ‘God/the Lord’ as a God of war and, thereby, to maintain an already existing ideology of war:We know now that a text is not a line of words releasing a single ‘theological’ meaning (the ‘message’ of the Author-God but a multi-dimensional space in which a variety of writings, none of them original, blend and clash. The text is a tissue of quotations drawn from the innumerable centres of culture. (Barthes, cited in Beal 1992:27

  1. The Awkward Academic: Why Judith Reads James in Joyce Carol Oates's "My Warszawa: 1980"

    Directory of Open Access Journals (Sweden)

    Kerry Sutherland

    2015-12-01

    Full Text Available Joyce Carol Oates’s short story “My Warszawa: 1980” follows the journey of well-respected academician Judith Horne as she travels to and within Poland to participate in an international conference on American culture. She has a vague connection to Poland, with remote family members who were killed in Auschwitz and a Jewish ancestry that can be seen in her features, but she considers these facts unimportant to who she is at the moment. She travels with her lover, who is as remote emotionally as her dead forbears are physically. The emotional connections she makes with the people and land begin to affect her well-ordered and controlled life, including her relationship with him. As they sit side by side on the plane to Poland, he attends to his work as journalist, typewriter on his lap, and Judith gazes at the landscape, an opened book on hers. It is Henry James’s The Awkward Age, unread, chosen by Judith with a logic she cannot recall. Why does Oates give James to Judith, and why does she choose this novel in particular to influence her? Nanda’s story is a warning to Judith, a red flag that unfolds as the younger girl’s ruin proceeds before her eyes, and Judith realizes that the man she loves will never marry her, just as Vanderbank refuses to propose to Nanda. Neither man is comfortable with a woman who is corrupted by knowledge that might undermine his need for authority in the relationship. Nanda understands her position too late, but Judith has time to reflect on her situation, and Oates leaves the story unfinished, with Judith on a plane home with Carl but not definitively resigned to the relationship.

  2. Judith Butler's theories: reflections for nursing research and practice.

    Science.gov (United States)

    Nagington, Maurice G

    2016-10-01

    Judith Butler is one of the most influential late 20th and early 21st century philosophers in regard to left wing politics, as well as an active campaigner for social justice within the United States and worldwide. Her academic work has been foundational to the academic discipline of queer theory and has been extensively critiqued and applied across a hugely wide range of disciplines. In addition, Butler's work itself is extensive covering topics such as gender, sexuality, race, literary theory, and warfare. This article can only serve as a taster for the potential application of her work in relation to nursing, which is in its infancy. This introduction covers three of the potentially most productive themes in Butler's work, namely power, performativity, and ethics. Each of these themes are critically explored in turn, sometimes in relation to their actual application in nursing literature, but also in relation to their potential for producing novel critiques of nursing practice. Suggestions are made about how Butler's work can develop nursing research and practice. The article concludes with a short summary of Butler's key works as well as suggested reading for people interested in examining how her theories have been applied across different academic settings.

    2015-10-01

    Dixon and colleagues (Behavior Analysis in Practice 8(1):7-15, 2015) used publication rates of faculty in programs with Behavior Analyst Certification Board (BACB) approved course sequences as a proxy measure for the quality of the program. The paper is important because it begins a conversation about what the characteristics of a quality program should be. Low publication rates for most of these programs and their faculties were a source of concern for Dixon, et al., but from the perspective of measurement validity, this finding is not necessarily bad news. Program quality is a multi-dimensional construct, and for some dimensions, publication rates are likely to be irrelevant.

    2011-01-01

    New representation of the exact Mathisson-Papapetrou-Dixon equations at the Mathisson-Pirani condition in the Kerr metric which does not contain the third-order derivatives of the coordinates of a spinning particle is obtained. For this purpose the integrals of energy and angular momentum of the spinning particle as well as a differential relationship following from the Mathisson-Papapetrou-Dixon equations are used. The form of these equations is adapted for their computer integration with the aim of further investigations of the influence of the spin-curvature interaction on the particle's behavior in the gravitational field without restrictions on its velocity and spin orientation.

    To compare systematically quantitative MRI, MR spectroscopy (MRS), and different histological methods for liver fat quantification in order to identify possible incongruities. Fifty-nine consecutive patients with liver disorders were examined on a 3 T MRI system. Quantitative MRI was performed using a dual- and a six-echo variant of the modified Dixon (mDixon) sequence, calculating proton density fat fraction (PDFF) maps, in addition to single-voxel MRS. Histological fat quantification included estimation of the percentage of hepatocytes containing fat vesicles as well as semi-automatic quantification (qHisto) using tissue quantification software. In 33 of 59 patients, the hepatic fat fraction was >5% as determined by MRS (maximum 45%, mean 17%). Dual-echo mDixon yielded systematically lower PDFF values than six-echo mDixon (mean difference 1.0%; P estimated percentage of hepatocytes containing fat vesicles (R = 0.984, 0.967, 0.941, respectively, all P estimated percentage of hepatocytes containing fat were higher by a factor of 2.5 in comparison to qHisto. Six-echo mDixon and MRS showed the best agreement with values obtained by qHisto. Six-echo mDixon, MRS, and qHisto provide the most robust and congruent results and are therefore most appropriate for reliable quantification of liver fat. • Six-echo mDixon correlates excellently with MRS, qHisto, and the estimated percentage of fat-containing hepatocytes. • Six-echo mDixon, MRS, and qHisto provide the most robust and congruent results. • Dual-echo mDixon yields systematically lower PDFF values than six-echo mDixon. • The percentage of fat-containing hepatocytes is 2.5-fold higher than fat fraction determined by qHisto. • Performance characteristics and systematic differences of the various methods should be considered.

    2011-03-01

    Full Text Available An intertextual analysis of the character of Achior in the book of Judith shows that the author of the book proposes a changed Judaean identity. The way in which he depicts the character of Judith and her alter ego, Achior, illustrates the author’s ideology that people like proselytes and marginalised widows are not only to be included in the society, but can even be the leaders of the community. A nationalistic and exclusivist approach is entwined in the narrative with an inclusivist viewpoint propagating a new identity for the people of that time.

    The interaction of hot plasma with material in fusion devices can result in material erosion and irreversible damage. Carbon based materials are proposed for ITER divertor armour. To simulate carbon erosion under high heat fluxes, electron beam heating in the JUDITH facility has been used. In this paper, carbon erosion under energetic electron impact is modeled by the 3D thermomechanics code 'PEGASUS-3D'. The code is based on a crack generation induced by thermal stress. The particle emission observed in thermal shock experiments is a result of breaking bonds between grains caused by thermal stress. The comparison of calculations with experimental data from JUDITH shows good agreement for various incident power densities and pulse durations. A realistic mean failure stress has been found. Pre-heating of test specimens results in earlier onset of brittle destruction and enhanced particle loss in agreement with experiments.

    In October through November 2006, scientists from the U. S. Geological Survey (USGS) Eastern Region Earth Surface Processes Team (EESPT) and the Raleigh (N.C.) Water Science Center (WSC), in cooperation with the North Carolina Geological Survey (NCGS) and the Onslow County Water and Sewer Authority (ONWASA), drilled a stratigraphic test hole and well in Onslow County, N.C. The Dixon corehole was cored on ONWASA water utility property north of the town of Dixon, N.C., in the Sneads Ferry 7.5-minute quadrangle at latitude 34deg33'35' N, longitude 77deg26'54' W (decimal degrees 34.559722 and -77.448333). The site elevation is 66.0 feet (ft) above mean sea level as determined using a Paulin precision altimeter. The corehole attained a total depth of 1,010 ft and was continuously cored by the USGS EESPT drilling crew. A groundwater monitoring well was installed in the screened interval between 234 and 254 ft below land surface. The section cored at this site includes Upper Cretaceous, Paleogene, and Neogene sediments. The Dixon core is stored at the NCGS Coastal Plain core storage facility in Raleigh. The Dixon corehole is the fourth and last in a series of planned North Carolina benchmark coreholes drilled by the USGS Coastal Carolina Project. These coreholes explore the physical stratigraphy, facies, and thickness of Cretaceous, Paleogene, and Neogene Coastal Plain sediments in North Carolina. Correlations of lithologies, facies, and sequence stratigraphy can be made with the Hope Plantation corehole, N.C., near Windsor in Bertie County (Weems and others, 2007); the Elizabethtown corehole, near Elizabethtown, N.C., in Bladen County (Self-Trail and others, 2004b); the Smith Elementary School corehole, near Cove City, N.C., in Craven County (Harris and Self-Trail, 2006; Crocetti, 2007); the Kure Beach corehole, near Wilmington, N.C., in New Hanover County (Self-Trail and others, 2004a); the Esso#1, Esso #2, Mobil #1, and Mobil #2 cores in Albermarle and Pamlico Sounds

    BACKGROUND. Dysregulated lipid and glucose metabolism in clear cell renal cell carcinoma (ccRCC) has been implicated in disease progression, and whole tumor tissue–based assessment of these changes is challenged by the tumor heterogeneity. We studied a noninvasive quantitative MRI method that predicts metabolic alterations in the whole tumor. METHODS. We applied Dixon-based MRI for in vivo quantification of lipid accumulation (fat fraction [FF]) in targeted regions of interest of 45 primary ccRCCs and correlated these MRI measures to mass spectrometry–based lipidomics and metabolomics of anatomically colocalized tissue samples isolated from the same tumor after surgery. RESULTS. In vivo tumor FF showed statistically significant (P quantitative Dixon-based MRI as a biomarker of reprogrammed lipid metabolism in ccRCC, which may serve as a predictor of tumor aggressiveness before surgical intervention.

    Full Text Available O texto expõe o ponto de vista de duas grandes filósofas feministas da atualidade, Adriana Cavarero e Judith Butler, sobre subjetividade e relacionalidade, mostrando como ambas distanciaram-se dos temas específicos do feminismo de maneira a aprofundar e ampliar suas reflexões sobre política e ética. Questionando a tradição, Cavarero não compactua nem com o binarismo metafísico nem com a impessoalidade pós-moderna, combinando uma perspectiva feminista com a arendtiana da subjetividade embasada na relacionalidade. No entanto, diferentemente do pensamento de Cavarero, sob a perspectiva desconstrucionista de Butler a linguagem molda corpo e identidade. A subjetividade está presa às normas e valores sociais. Butler e Cavarero repensam a subjetividade, alinhando-se quanto à relacionalidade, ou seja, deslocando a política para longe do ser imune e realocando-a no ser vulnerável em relação com o outro e com os efeitos das regras e valores sociais impostos.The work presents the standpoint of two important contemporary feminist philosophers, Adriana Cavarero and Judith Butler, on subjectivity and relationality, showing how both moved away from the specific feminism motif in order to deepen and broaden their reflection on politics and ethics. Calling tradition into question, Cavarero agrees neither with the metaphysical binary, nor with the post-modern impersonality, combining a feminist and the arendtian perspectives of the subjectivity based on relationality. Contrary to Cavarero's thought, though, under Butler's deconstructionist standpoint language shapes body and identity. Subjectivity is "trapped" into social norms and values. Both Butler and Cavarero rethink subjectivity based on relationality, that is, displacing politics from the immune individual and reallocating it on the vulnerable individual in relation with the other and with the social rules and values imposed on them.

    There is growing evidence that pericardial and epicardial fat volume (PFV, EFV) are associated with cardiovascular risk. We evaluated a novel method for accurate measurement of PFV and EFV using a 3D-Dixon based cardiac magnetic resonance (CMR) approach. An electrocardiography triggered and respiratory navigator gated 3D-gradient echo pulse sequence was used for cardiac Dixon imaging. Based on this sequence, voxels predominantly containing fat were identified and added up for volumetry. After accuracy assessment in phantoms, consisting of muscle tissue and seven different fat samples (50-200 ml), the sequence was acquired in 34 healthy volunteers (22 male, BMI range 14-42 kg/m(2), age range 21-79 years) at 1.5 T. Analysis was performed independently by two readers who draw two 3D-regions of interest, one for EFV and one for PFV. Additionally, EFV and PFV were compared between overweighted and non-overweighted subjects. The phantom study showed an excellent agreement of measured and true fat volumes (maximum difference = 6 %, linear correlation coefficient R = 1.00). PFV over all volunteers was 158.0 ± 126.4 ml and EFV was 77.0 ± 55.3 ml. PFV and EFV were highly correlated (R = 0.96). Inter-reader agreement was good with a mean difference of 0.2 ± 5.6 and 4.5 ± 4.2 ml for PFV/EFV, (R > 0.99, each). EFV and PFV differed significantly between subjects with BMI > 25 kg/m(2) and BMI < 25 kg/m(2), n = 17 each (PFV 219.0 ± 151.8 vs. 96.9 ± 44.7 ml and EFV 102.3 ± 66.3 vs. 51.7 ± 23.6 ml, p < 0.001, each). The proposed 3D-Dixon based method allows accurate measurement of cardiac fat volumes. It provides a valuable tool for cardiovascular risk stratification by CMR.

    To quantify the muscle fat-content (MFC) in phantoms, volunteers and patients with achillodynia using two-point Dixon-based magnetic resonance imaging (2pt-MRI{sub DIXON}) in comparison to MR spectroscopy (MRS) and visual assessment of MFC. Two-point Dixon-based MRI was used to measure the MFC of 15 phantoms containing 0-100 % fat-content and calf muscles in 30 patients (13 women; 57 ± 15 years) with achillodynia and in 20 volunteers (10 women; 30 ± 14 years) at 1.5 T. The accuracy of 2pt-MRI{sub DIXON} in quantification of MFC was assessed in vitro using phantoms and in vivo using MRS as the standard of reference. Fat-fractions derived from 2pt-MRI{sub DIXON} (FF{sub DIXON}) and MRS (FF{sub MRS}) were related to visual assessment of MFC (Goutallier grades 0-4) and Achilles-tendon quality (grade 0-4). Excellent linear correlation was demonstrated for FF{sub DIXON} with phantoms and with FF{sub MRS} in patients (p{sub c} = 0.997/0.995; p < 0.001). FF{sub DIXON} of the gastrocnemius muscle was significantly higher (p = 0.002) in patients (7.0 % ± 4.7 %) compared with volunteers (3.6 % ± 0.7 %), whereas visual-grading showed no difference between both groups (p > 0.05). FF{sub MRS} and FF{sub DIXON} were significantly higher in subjects with (>grade 1) structural damage of the Achilles-tendon (p = 0.01). Two-point Dixon-based MRI allows for accurate quantification of MFC, outperforming visual assessment of calf muscle fat. Structural damage of the Achilles tendon is associated with a significantly higher MFC. (orig.)

    We examined the influence of a single exercise session on quantitative muscle fat fraction MRI measurements. Ten healthy volunteers were scanned on a 3T body scanner before and after a session of bilateral squats until muscular fatigue. Axial in- and opposed phase images were acquired at a fixed distance from the knee joint and fat fractions were calculated using a 2-point Dixon technique as well as muscle cross sectional area at the same position. After the squat session, calculated fat fraction in the quadriceps bilaterally appeared to be significantly decreased, while all but one non-exercised muscles showed no change. In conclusion exercise might modify the measured apparent fat fraction. Trials using quantitative MRI should consider the timing of scanning sessions and physical examinations to avoid bias caused by the influence of exercise on measurements.

  11. Dixon-type and subtraction-type contrast-enhanced magnetic resonance angiography: A theoretical and experimental comparison of SNR and CNR.

    2014-07-17

    The purpose of this work is to compare the behavior of the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) in contrast-enhanced MR angiography with background suppression performed by either a Dixon-type or subtraction-type method. Theoretical expressions for the SNR and CNR for both background suppression techniques were derived. The theoretical Dixon:subtraction SNR and CNR ratios were compared to empirical ratios measured from phantom and in vivo studies for Dixon techniques utilizing one, two, and three echoes. Specifically, the SNR and CNR ratios were compared as the concentration of contrast material in the blood changed. Empirical measurements of the SNR and CNR ratios compared favorably with the ratios predicted by theory. As the contrast concentration was reduced, the SNR advantage of the Dixon techniques increased asymptotically. In the ideal case, the SNR improvement over subtraction contrast-enhanced MR angiography was at least twofold for one- and two-echo Dixon techniques and at least a factor of 6 for the three-echo Dixon technique. Expressions showing a contrast concentration-dependent SNR and CNR improvement of at least a factor of two when Dixon-type contrast-enhanced MR angiography is used in place of subtraction-type contrast-enhanced MR angiography were derived and validated with phantom and in vivo experiments.

    To intra-individually compare the diagnostic image quality of Dixon and spectral fat suppression at 3 T. Fifty consecutive patients (mean age 55.1 years) undergoing 3 T breast MRI were recruited for this prospective study. The image protocol included pre-contrast and delayed post-contrast spectral and Dixon fat-suppressed T1w series. Two independent blinded readers compared spectral and Dixon fat-suppressed series by evaluating six ordinal (1 worst to 5 best) image quality criteria (image quality, delineation of anatomical structures, fat suppression in the breast and axilla, lesion delineation and internal enhancement). Breast density and size were assessed. Data analysis included Spearman's rank correlation coefficient and visual grading characteristics (VGC) analysis. Four examinations were excluded; 48 examinations in 46 patients were evaluated. In VGC analysis, the Dixon technique was superior regarding image quality criteria analysed (P < 0.01). Smaller breast size and lower breast density were significantly (P < 0.01) correlated with impaired spectral fat suppression quality. No such correlation was identified for the Dixon technique, which showed reconstruction-based water-fat mixups leading to insufficient image quality in 20.8 %. The Dixon technique outperformed spectral fat suppression in all evaluated criteria (P < 0.01). Non-diagnostic examinations can be avoided by fat and water image reconstruction. The superior image quality of the Dixon technique can improve breast MRI interpretation. (orig.)

    To evaluate quantification of early fatty infiltration in supraspinatus muscles with magnetic resonance (MR) imaging using a T2*-corrected multi-echo 3D-gradient-echo Dixon-based sequence (multi-echo Dixon) and compare it to proton-MR-spectroscopy. Sixty subjects (mean age 46 years, 41 men) with good supraspinatus muscle quality on 1.5 T MR imaging were included. Fat percentage (FP) in the supraspinatus muscle was quantified using a multi-echo Dixon compared to single-voxel MR spectroscopy as reference standard. In 18 subjects the multi-echo Dixon was repeated to assess test-retest reliability. Measurements based on multi-echo Dixon were performed by two independent readers by placing regions-of-interest (ROIs) in the supraspinatus muscle corresponding to the MR-spectroscopy voxel. Intraclass and concordance correlation coefficients (ICC/CCC) were used for statistical analysis. Test-retest reliability was substantial for reader 1 (ICC = 0.757) and almost perfect for reader 2 (ICC = 0.873). Inter-reader reliability for multi-echo Dixon was almost perfect (ICC = 0.893, P <.0005). Mean FP in all 60 subjects with multi-echo Dixon was 3.5 ± 1.6 for reader 1, 3.7 ± 1.8 for reader 2, and 2.8 ± 1.4 with MR spectroscopy. Correlation between multi-echo Dixon and MR spectroscopy was moderate (CCC = 0.641). The multi-echo Dixon sequence is a reliable method and comparable to MR-spectroscopy for quantification of low levels of fatty infiltration in the supraspinatus muscle. (orig.)

    Full Text Available Purpose: To evaluate a potential approach for improved attenuation correction (AC of PET in simultaneous PET and MRI brain imaging, a straightforward approach that adds bone information missing on Dixon AC was explored. Methods: Bone information derived from individual T1-weighted MRI data using segmentation tools in SPM8, were added to the standard Dixon AC map. Percent relative difference between PET reconstructed with Dixon+bone and with Dixon AC maps were compared across brain regions of 13 oncology patients. The clinical potential of the improved Dixon AC was investigated by comparing relative perfusion (rCBF measured with arterial spin labeling to relative glucose uptake (rPETdxbone measured simultaneously with 18F-flurodexoyglucose in several regions across the brain. Results: A gradual increase in PET signal from center to the edge of the brain was observed in PET reconstructed with Dixon+bone. A 5-20% reduction in regional PET signals were observed in data corrected with standard Dixon AC maps. These regional underestimations of PET were either reduced or removed when Dixon+bone AC was applied. The mean relative correlation coefficient between rCBF and rPETdxbone was r = 0.53 (p<0.001. Marked regional variations in rCBF-to-rPET correlation were observed, with the highest associations in the caudate and cingulate and the lowest in limbic structures. All findings were well matched to observations from previous studies conducted with PET data reconstructed with computed tomography derived AC maps. Conclusion: Adding bone information derived from T1-weighted MRI to Dixon AC maps can improve underestimation of PET activity in hybrid PET-MRI neuroimaging.

    Our aim was to develop a partial volume (PV) correction method of choline (Cho) signals detected by breast 3D-magnetic resonance spectroscopic imaging (3D-MRSI), using information from water/fat-Dixon MRI. Following institutional review board approval, five breast cancer patients were measured at 3 T. 3D-MRSI (1 cm{sup 3} resolution, duration ∝11 min) and Dixon MRI (1 mm{sup 3}, ∝2 min) were measured in vivo and in phantoms. Glandular/lesion tissue was segmented from water/fat-Dixon MRI and transformed to match the resolution of 3D-MRSI. The resulting PV values were used to correct Cho signals. Our method was validated on a two-compartment phantom (choline/water and oil). PV values were correlated with the spectroscopic water signal. Cho signal variability, caused by partial-water/fat content, was tested in 3D-MRSI voxels located in/near malignant lesions. Phantom measurements showed good correlation (r = 0.99) with quantified 3D-MRSI water signals, and better homogeneity after correction. The dependence of the quantified Cho signal on the water/fat voxel composition was significantly (p < 0.05) reduced using Dixon MRI-based PV correction, compared to the original uncorrected data (1.60-fold to 3.12-fold) in patients. The proposed method allows quantification of the Cho signal in glandular/lesion tissue independent of water/fat composition in breast 3D-MRSI. This can improve the reproducibility of breast 3D-MRSI, particularly important for therapy monitoring. (orig.)

    This work investigates and compares two different phase-correction algorithms for Dixon fat-water separation and two different quality maps (QM) for region-growing: the original QM, based on phase gradients, and a QM based on phase uncertainty, proposed in this article. A spoiled dual-gradient-echo sequence was employed at 1.5 T to acquire in-phase and out-of-phase images of joints, parotid glands, abdomen and test objects. All 97 datasets were processed eight times each: with two different phase correction algorithms (original and hierarchical phase correction), with two different QM, and with/without removing linear component of the phase drifts associated with dual-echo acquisitions and bipolar readout gradient waveforms. The linear component of the phase drift along the readout direction was found to reach 4.1° pixel-1, depending on the geometric parameters. Pre-processing to remove linear phase shifts has little impact on outcome. The hierarchic phase-correction algorithm outperformed the original phase-correction algorithm in all applications. The proposed phase-uncertainty QM provides a small performance improvement in clinical images, but can be vulnerable to flow-related phase shifts in bright vessels. Overall the most successful phase-correction technique employed phase-uncertainty QMs and hierarchic algorithms, with pre-processing to correct the linear phase drift associated with dual-echo acquisitions and bipolar readout gradient waveform.

    The aim of this study was to demonstrate that gradient-echo sampling of single spin echoes can be used to isolate the signal from trabecular bone marrow, with high-quality segmentation and surface reconstructions resulting from the application of simple post-processing strategies. Theoretical expressions of the time-domain single-spin-echo signal were used to simulate signals from bone marrow, non-bone fatty deposits and muscle. These simulations were compared with and used to interpret signals obtained by the application of the gradient-echo sampling of a spin-echo sequence to image the knee and surrounding tissues at 1.5 T. Trabecular bone marrow has a much higher reversible transverse relaxation rate than surrounding non-bone fatty deposits and other musculoskeletal tissues. This observation, combined with a choice of gradient-echo spacing that accentuates Dixon-type oscillations from chemical-shift interference effects, enabled the isolation of bone marrow signal from surrounding tissues through the use of simple image subtraction and thresholding. Three-dimensional renderings of the marrow surface were then readily generated with this approach - renderings that may prove useful for bone morphology assessment, e.g. for the measurement of femoral anteversion. In conclusion, understanding the behavior of signals from bone marrow and surrounding tissue as a function of time through a spin echo facilitates the segmentation and reconstruction of bone marrow surfaces using straightforward post-processing strategies that are typically available on modern radiology workstations.

    Magnetic resonance spectroscopy of the liver requires input from a physicist or physician at the time of acquisition to insure proper voxel selection, while in multiecho chemical shift imaging, numerous regions of interest must be manually selected in order to ensure analysis of a representative portion of the liver parenchyma. A fully automated technique could improve workflow by selecting representative portions of the liver prior to human analysis. Complete volumes from three-dimensional gradient dual-echo acquisitions with two-point Dixon reconstruction acquired at 1.5 and 3 T were analyzed in 100 subjects, using an automated liver sampling algorithm, based on ratio pairs calculated from signal intensity image data as fat-only/water-only and log(in-phase/opposed-phase) on a voxel-by-voxel basis. Using different gridding variations of the algorithm, the average correct liver volume samples ranged from 527 to 733 mL. The average percentage of sample located within the liver ranged from 95.4 to 97.1%, whereas the average incorrect volume selected was 16.5-35.4 mL (2.9-4.6%). Average run time was 19.7-79.0 s. The algorithm consistently selected large samples of the hepatic parenchyma with small amounts of erroneous extrahepatic sampling, and run times were feasible for execution on an MRI system console during exam acquisition.

Cernea, a development social scientist who has militated throughout his academic career and applied work for "putting people first", in the forefront of development projects and policies. Working for a long time for the promotion of anthropological and sociological knowledge, either in the activities of the World Bank or in the policies and programs of governments of both developed and developing countries, Dr. Cernea cleared pathways for applied social science that are sure to benefit people in development settings for many years to come. Undoubtedly many readers already know Dr. Cernea's work well, especially those of us who teach the anthropology of development or work in applied settings and organizations, but this interview embeds his broad body of work into a personal, human, and at times tragic context that opens with brushes with death, Nazi brutality, and exile. It also provides valuable insights for carrying out the work of development anthropologists within large-scale organizations and governments.This interview with Dr. Cernea was conducted by Dr. Judith Freidenberg, of the University of Maryland, on June 30, 2003, for the Society for Applied Anthropology Oral History Project, headquartered at the University of Kentucky Libraries. This Project aims to create, through the vehicle of oral histories, a record of the life, activities and experiences of number of selected scholars-anthropologists who devoted a great part of their scientific work to research, to applied work in different settings, to inducing development, including to hands-on work on crafting public social policies and actual development programs.

    Many place in Archean greenstone belts have been reported of the black chert to Iron rich sediments above volcanic sequence. The chemical sedimentary sequence has been recognized to form by as hydrothermal siliceous sequence. These sediments contain the hint to understand the Archean ocean and earth surface environments. Here, we will focus the Dixon Island and Cleaverville formations, which are one of the best preserved Archean hydrothermal sedimentary sequence in the world, to recognized detail stratigraphy and restored deep ocean environment. We did scientific drilling, which is called ‘DXCL drilling project’, at 2007 summer. This drilling project had been selected two coastal sites; CL site at lower part of the Cleaverville Formation, and another is DX site at the upper Dixon Island Formation. A systematic combinations of geological, sedimentological, geochemical, and geobiological approaches will be applied to the fresh samples. Here we will show the recent result of this sequence, which will be key evidence to understand the nature of the middle Archean (3.2 Ga) marine environment influenced by hydrothermal activity. The 3.2 Ga Dixon Island -Cleaverville formations composed of volcanic rock units and chemical-volcanosedimentary sequence which are identified by accreted immature island arc setting. The ~350m-thick Dixon Island Formation which is overlie by pillow basalt consists mainly of highly silicified volcanic-siliceous sequences that contain apparent microbial mats and bacterial fossil-like structure within black chert and also includes a komatiite-rhyolite sequences bearing hydrothermal veins. The >300m-thick Cleaverville Formation, which conformably overlay pillow basalt, contains a thick unit of reddish shale, bedded red-white chert and banded iron formation. It partly contains chert fragments-bearing pyroclastic beds. In detail lithology from the drill cores, the CL and DX contain different type of organic rocks. The CL 1 and CL2 core samples

    Accurate, non-invasive method of fat estimation is a valuable test for evaluation of diseases with abnormal hepatic fat. To determine the accuracy of mDixon MR technique in assessment of liver fat over CT and to correlate the CT and MRI findings with biopsy. A prospective observational study was conducted at Imaging Services of Narayana Multispeciality Hospital between March 2011- December 2012. Thirty patients who attended the clinic for non-hepatic complaints were included in the study. Patients with known liver disease, cirrhosis, alcoholic liver disease, bleeding diathesis and claustrophobic patients were excluded from the study. Subjects underwent sonography, CT liver and MR examination of liver for fat estimation using mDixon protocol. Biopsy of the liver was performed either by image guidance or by direct biopsy. Liver Attenuation Index (LAI), fat estimation by MR methods were reviewed independently by two observers and compared with biopsy results. The statistical analysis was performed by SPSS. Pearson correlation was used to find the correlation between the left and right lobe of liver segments by CT and histological correlation. There was good correlation between the MR estimation of liver fat and histological grading. Majority (90%) of patients had fat content of less than 10%. Maximal fat content of 28% was observed in one patient. LAI values poorly correlated with the MRI and histological observations. MR estimation of the liver using mDixon technique yielded specific information about liver fat, correlated well with the histological grading. Technique is more accurate than CT, does not involve ionising radiation, hence recommended as method of choice.

    Full Text Available In this paper we propose to look into different meanings of livability and life in Judith butler’s thought. Although crucial for her early work (she points to it in her 1999 Introduction to Gender Trouble, the concept of livability as such emerges more often and in a more pronounced manner in her later books (from Undoing Gender and Precarious life to Towards a Performative Theory of Assembly. Our main question is: what is the thread that runs through different concepts of life in butler’s work? What are the links between abject, unlivable, precarious, ungrievable, jettisoned and dispossessed life? this raises further questions: the question of gradation of livability (which life matters and ‘how much’, and how to think this quantifiability of something so unquantifiable; and the question of universality (all lives matter. these questions obviously need to take into account the terms under which a life is qualified and counted as livable. such conditions encompass the norms that organize the possibility of recognition and the orders of recognizability and differential allocation of humanness. they encompass the ways in which we are constituted politically, but also in which this ‘we’ is social and bodily. the question of livable life is thus very much entangled with the issue of (individual agency, but also with what we as agents require “in order to maintain and reproduce the conditions of (our own livability” (Undoing Gender 2004: 39.

    Highlights: • Monitoring of the much faster electron beam motion by IR camera through a synchronized frame triggering. • Estimation of the heat flux generated by electron beam guns based on calorimetry and FEM simulations. • Consideration of the inclined electron beam loading of rectangular-shaped objects. - Abstract: Three beryllium-armoured small-scale mock-ups and one semi-prototype for the ITER first wall were tested by the electron beam facility JUDITH 2 at Forschungszentrum Jülich. Both testing campaigns with cyclic loads up to 2.5 MW/m{sup 2} are carried out in compliance with the extensive quality and management specifications of ITER Organization (IO) and Fusion for Energy (F4E). Several dedicated calibration experiments were performed before the actual testing in order to fulfil the testing requirements and tolerances. These quality requests have been the motivation for several experimental setup improvements. The most relevant results of these activities, being the electron beam monitoring and the heat flux flatness verification, will be presented.

    Full Text Available In this paper we take Judith Butler’s thinking as a basis from which to consider the ideas of three authors. In our view, these authors complement Butler’s project of helping excluded people to fight for a dignified life, a “liveable life”; and specifically to the idea of using performative resignifications of discourses and practices. On one hand, we present the writings of Sarah Ahmed and Lanei Rodemeyer; they consider the spatiality and temporality of the lived body (Ahmed and the relationship between the lived body and discourse (Rodemeyer. In both cases, “pure phenomenology” (and not hermeneutics is applied to the question of sexual diversity. On the other hand, we delve into the works of Louise Bourgeois, for whom artistic creation is a way of exorcising pain and becoming free of socially constructed prisons. Starting from the paths opened by these authors, we believe that a phenomenology is possible in which there is place for what does not fit into the norm. this phenomenology would make it possible, on one side, to rend visibility to those who do not fit into the established norms and categories and, on another side, to contribute to a reformulation of discourse, such a transformation that allows the excluded to inhabit them. “Pure” phenomenology, that aims at going to “the things themselves” do not naturalise oppressions, but it is rather an ally to recognise, denounce and provide a reparation for them.

    Full Text Available This article aims to carry out a multidisciplinary reading of 'Mason & Dixon' starting from the apparitions of what might only look like a "stage prop", a rifle in four more or less important moments of the novel. By applying a stereoscopic reading of the novel, which may achieve depth by means of comparing different textual objects and a wider historical context (that of the history of firearms in the 17th and 18th century, plus other works by Pynchon featuring firearms, it will be shown how literary (textual avatars of "real", "historical" objects (firearms may at the same time be verbal constructs but refer to the technical, material features of those objects, establishing multi-dimensional and complex relations between technology, science, economics (early forms of globalization, politics (colonialism and colonial wars within and outside 'Mason & Dixon', and the rest of Pynchon's oeuvre. Moreover, this reading allows us to better understand how Pynchon may use the historical documents and literature he has found while researching his novels.

    Full Text Available Introduction. An increasing number of studies are utilizing different magnetic resonance (MR methods to quantify bone marrow fat due to its potential role in osteoporosis. Our aim is to compare the measurements of bone marrow fat among T1-weighted magnetic resonance imaging (MRI, modified Dixon method (also called fat fraction MRI (FFMRI, and magnetic resonance spectroscopy (MRS. Methods. Contiguous MRI scans were acquired in 27 Caucasian postmenopausal women with a modified Dixon method (i.e., FFMRI. Bone marrow adipose tissue (BMAT of T1-weighted MRI and bone marrow fat fraction of the L3 vertebra and femoral necks were quantified using SliceOmatic and Matlab. MRS was also acquired at the L3 vertebra. Results. Correlation among the three MR methods measured bone marrow fat fraction and BMAT ranges from 0.78 to 0.88 in the L3 vertebra. Correlation between BMAT measured by T1-weighted MRI and bone marrow fat fraction measured by modified FFMRI is 0.86 in femoral necks. Conclusion. There are good correlations among T1-weighted MRI, FFMRI, and MRS for bone marrow fat quantification. The inhomogeneous distribution of bone marrow fat, the threshold segmentation of the T1-weighted MRI, and the ambiguity of the FFMRI may partially explain the difference among the three methods.

    To assess whether multi-echo Dixon magnetic resonance (MR) imaging with simultaneous T2{sup *} estimation and correction yields more accurate fat-signal fraction (FF) measurement of the lumbar paravertebral muscles, in comparison with non-T2{sup *}-corrected two-echo Dixon or T2{sup *}-corrected three-echo Dixon, using the FF measurements from single-voxel MR spectroscopy as the reference standard. Sixty patients with low back pain underwent MR imaging with a 1.5T scanner. FF mapping images automatically obtained using T2{sup *}-corrected Dixon technique with two (non-T2{sup *}-corrected), three, and six echoes, were compared with images from single-voxel MR spectroscopy at the paravertebral muscles on levels L4 through L5. FFs were measured directly by two radiologists, who independently drew the region of interest on the mapping images from the three sequences. A total of 117 spectroscopic measurements were performed either bilaterally (57 of 60 subjects) or unilaterally (3 of 60 subjects). The mean spectroscopic FF was 14.3 ± 11.7% (range, 1.9-63.7%). Interobserver agreement was excellent between the two radiologists. Lin's concordance correlation between the spectroscopic findings and all the imaging-based FFs were statistically significant (p < 0.001). FFs obtained from the T2*-corrected six-echo Dixon sequences showed a significantly better concordance with the spectroscopic data, with its concordance correlation coefficient being 0.99 and 0.98 (p < 0.001), as compared with two- or three-echo methods. T2{sup *}-corrected six-echo Dixon sequence would be a better option than two- or three-echo methods for noninvasive quantification of lumbar muscle fat quantification.

There exists a great need for a theoretically rich critique and for practical improvements. Butler exemplarily analyses the publically debated case of an operative sex change, in which neither the critics nor the supporters sufficiently notes the concerned person’s own wishes. The weakness of the volume lies in the ambiguous use of the term gender.

  8. A New Brachylophosaurin Hadrosaur (Dinosauria: Ornithischia with an Intermediate Nasal Crest from the Campanian Judith River Formation of Northcentral Montana.

    Directory of Open Access Journals (Sweden)

    Elizabeth A Freedman Fowler

    Full Text Available Brachylophosaurini is a clade of hadrosaurine dinosaurs currently known from the Campanian (Late Cretaceous of North America. Its members include: Acristavus gagslarsoni, which lacks a nasal crest; Brachylophosaurus canadensis, which possesses a flat paddle-shaped nasal crest projecting posteriorly over the dorsal skull roof; and Maiasaura peeblesorum, which possesses a dorsally-projecting nasofrontal crest. Acristavus, from the lower Two Medicine Formation of Montana (~81-80 Ma, is hypothesized to be the ancestral member of the clade. Brachylophosaurus specimens are from the middle Oldman Formation of Alberta and equivalent beds in the Judith River Formation of Montana; the upper Oldman Formation is dated 77.8 Ma.A new brachylophosaurin hadrosaur, Probrachylophosaurus bergei (gen. et sp. nov. is described and phylogenetically analyzed based on the skull and postcranium of a large individual from the Judith River Formation of northcentral Montana (79.8-79.5 Ma; the horizon is equivalent to the lower Oldman Formation of Alberta. Cranial morphology of Probrachylophosaurus, most notably the nasal crest, is intermediate between Acristavus and Brachylophosaurus. In Brachylophosaurus, the nasal crest lengthens and flattens ontogenetically, covering the supratemporal fenestrae in large adults. The smaller nasal crest of Probrachylophosaurus is strongly triangular in cross section and only minimally overhangs the supratemporal fenestrae, similar to an ontogenetically earlier stage of Brachylophosaurus. Sutural fusion and tibial osteohistology reveal that the holotype of Probrachylophosaurus was relatively more mature than a similarly large Brachylophosaurus specimen; thus, Probrachylophosaurus is not simply an immature Brachylophosaurus.The small triangular posteriorly oriented nasal crest of Probrachylophosaurus is proposed to represent a transitional nasal morphology between that of a non-crested ancestor such as Acristavus and the large flat

    To establish a dedicated protocol for the three-dimensional (3D) quantification of plaque lipids in apolipoprotein E-deficient (apoE{sup -/-}) mice using ex vivo MRI. ApoE{sup -/-} mice were fed a high-fat diet (n = 10) or normal food (n = 10) for 3 months. Subsequently, a 3D FLASH MRI sequence was used to view the anatomy of the aortic root in the isolated hearts, where a 3D double-echo two-excitation pulse sequence (DIXON sequence) was used to selectively image plaque lipids. The vessel wall, lumen and plaque lipid volumes were quantified by MRI and histology for correlation analysis. DIXON MRI allowed visualisation and accurate quantification of plaque lipids. When comparing the vessel wall, lumen and plaque lipid sizes in the aortic root, Bland-Altman and linear regression analysis revealed a close correlation between MRI results and the histological data both on a slice-by-slice basis and of the volumetric measurements (vessel wall: r{sup 2} = 0.775, p < 0.001; vessel lumen: r{sup 2} = 0.875; p = 0.002; plaque lipid: r{sup 2} = 0.819, p = 0.003). The combination of 3D FLASH and DIXON-sequence MRI permits an accurate ex vivo assessment of the investigated plaque parameters in the aortic root of mice, particularly the lipid content. (orig.)

    Purpose: MR-based pseudo-CT has an important role in MR-based radiation therapy planning and PET attenuation correction. The purpose of this study is to establish a clinically feasible approach, including image acquisition, correction, and CT formation, for pseudo-CT generation of the brain using a single-acquisition, undersampled ultrashort echo time (UTE)-mDixon pulse sequence. Methods: Nine patients were recruited for this study. For each patient, a 190-s, undersampled, single acquisition UTE-mDixon sequence of the brain was acquired (TE = 0.1, 1.5, and 2.8 ms). A novel method of retrospective trajectory correction of the free induction decay (FID) signal was performed based on point-spread functions of three external MR markers. Two-point Dixon images were reconstructed using the first and second echo data (TE = 1.5 and 2.8 ms). R2{sup ∗} images (1/T2{sup ∗}) were then estimated and were used to provide bone information. Three image features, i.e., Dixon-fat, Dixon-water, and R2{sup ∗}, were used for unsupervised clustering. Five tissue clusters, i.e., air, brain, fat, fluid, and bone, were estimated using the fuzzy c-means (FCM) algorithm. A two-step, automatic tissue-assignment approach was proposed and designed according to the prior information of the given feature space. Pseudo-CTs were generated by a voxelwise linear combination of the membership functions of the FCM. A low-dose CT was acquired for each patient and was used as the gold standard for comparison. Results: The contrast and sharpness of the FID images were improved after trajectory correction was applied. The mean of the estimated trajectory delay was 0.774 μs (max: 1.350 μs; min: 0.180 μs). The FCM-estimated centroids of different tissue types showed a distinguishable pattern for different tissues, and significant differences were found between the centroid locations of different tissue types. Pseudo-CT can provide additional skull detail and has low bias and absolute error of

    The terrestrial Judith River Formation of northern Montana was deposited over an approximately 4 Myr interval during the Campanian (Late Cretaceous). Despite having been prospected and collected continuously by palaeontologists for over a century, few relatively complete dinosaur skeletons have been recovered from this unit to date. Here we describe a new genus and species of ankylosaurine dinosaur, Zuul crurivastator, from the Coal Ridge Member of the Judith River Formation, based on an exceptionally complete and well-preserved skeleton (ROM 75860). This is the first ankylosaurin skeleton known with a complete skull and tail club, and it is the most complete ankylosaurid ever found in North America. The presence of abundant soft tissue preservation across the skeleton, including in situ osteoderms, skin impressions and dark films that probably represent preserved keratin, make this exceptional skeleton an important reference for understanding the evolution of dermal and epidermal structures in this clade. Phylogenetic analysis recovers Zuul as an ankylosaurin ankylosaurid within a clade of Dyoplosaurus and Scolosaurus, with Euoplocephalus being more distantly related within Ankylosaurini. The occurrence of Z. crurivastator from the upper Judith River Formation fills a gap in the ankylosaurine stratigraphic and geographical record in North America, and further highlights that Campanian ankylosaurines were undergoing rapid evolution and stratigraphic succession of taxa as observed for Laramidian ceratopsids, hadrosaurids, pachycephalosaurids and tyrannosaurids.

    Hybrid positron emission tomography and magnetic resonance (PET/MR) imaging performs a two-point Dixon MR sequence for attenuation correction. However, MR data in hybrid PET/MR should provide anatomic and morphologic information as well as an attenuation map. We evaluated the Dixon sequence of hybrid PET/MR for anatomic correlation of PET-positive lesions compared with contrast-enhanced PET/computed tomography (CT) in patients with oncologic diseases. Twelve patients underwent a single injection, dual imaging protocol. PET/CT was performed with an intravenous contrast agent (85±13 min after {sup 18}F-FDG injection of 403± 45 MBq) and then (125±19 min after injection) PET/MR was performed. Attenuation correction and anatomic allocation of PET were performed using contrast-enhanced CT for PET/CT and Dixon MR sequence for hybrid PET/MR. The Dixon MR sequence and contrast-enhanced CT were compared for anatomic correlation of PET-positive lesions (scoring scale ranging from 0 to 3 for visual ratings). Additionally, standardized uptake values (SUVs) for the detected lesions were assessed for quantitative comparison. Both hybrid PET/MR and contrast-enhanced PET/CT identified 55 lesions with increased FDG uptake in ten patients. In total, 28 lymph nodes, 11 bone lesions, 3 dermal nodules, 3 pleural thickening lesions, 2 thyroid nodules, 1 pancreas, 1 liver, 1 ovary, 1 uterus, 1 breast, 1 soft tissue and 2 lung lesions were present. The best performance was observed for anatomic correlation of PET findings by the contrast-enhanced CT scans (contrast-enhanced CT, 2.64± 0.70; in-phase, 1.29±1.01; opposed-phase, 1.29±1.15; water-weighted, 1.71±1.07; fat weighted, 0.56±1.03). A significant difference was observed between the scores obtained from the contrast-enhanced CT and all four coregistered Dixon MR images. Quantitative evaluation revealed a high correlation between the SUVs measured with hybrid PET/MR (SUVmean, 2.63±1.62; SUVmax, 4.30±2.88) and contrast

    Full Text Available En el presente artículo se abordan los aportes de Judith Butler en torno al concepto de ciudadanía. Si bien Butler no ha desarrollado una teoría sistemática de la ciudadanía se sostiene que su concepción puede ser reconstruida a partir de su propuesta de ontología social y su interpretación de la contradicción performativa. Para probar esta afirmación, en primer lugar, se realiza dicha reconstrucción. En segundo lugar, se deriva de esta reconstrucción un modo original para pensar el ejercicio de la ciudadanía en los términos de la contradicción performativa. En tercer lugar, se evaluará la conveniencia de este punto de vista para comprender las demandas ciudadanas radicales en la actualidad. Como ejemplo se analizará la demanda de la legalización del aborto en Argentina. En la medida en que esta demanda incluye la realización de abortos medicamentosos, expresa el ejercicio de un derecho que las mujeres aún no poseen legalmente.

    Full Text Available Las autoras de este artículo integramos un proyecto de investigación cuyo objetivo es analizar las articulaciones de subjetividad y agencia que se producen a partir del entramado de los clivajes étnico, de clase, de género y de edad. Partimos de entender que ninguno de estos clivajes opera separado de los demás sino que las subjetividades y las agencias emergen de una trama en la que los posicionamientos que visibilizan alguno de los clivajes implican otros que operan sin ser visibles. Tomamos como instrumentos conceptuales dos propuestas teóricas de Judith Butler. La primera de ellas tiene que ver con el debate en el campo de la teoría feminista por los supuestos etnocéntricos que subyacen al postulado de que la diferencia de género es anterior a otras diferencias y constituye una esfera autónoma de relaciones. La segunda es el uso de la metáfora del travestismo para analizar casos en los que la rearticulación de subjetividad falla en la materialización de la norma que es necesaria para completar la identificación. Con estos instrumentos teóricos analizaremos travestismos de género, clase, edad y etnicidad en Río Negro y Chubut.

    The U.S. Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA) are working together to study sea-floor environments off the northeast coast of the United States. During 2008, NOAA survey H11996 collected multibeam echosounder data in a 65-square kilometer area in central Rhode Island Sound, southeast of Point Judith, Rhode Island. During 2010, the USGS collected bottom photographs and sediment samples from 25 stations in this study area. The bathymetry, photography, and sediment data are used to interpret sea-floor features including scour depressions, sand waves, trawl marks, and dredge spoils. Scour depressions cover the bathymetric highs in much of the study area. Sand waves are located mostly in the southwest, and trawl marks tend to be in the northern regions. Dredge spoils are located at a disposal site in a bathymetric low in the western end of the study area. Most stations have a sea-floor surface of sand or silty sand, but eight of the stations have boulders to pea-sized gravel or gravelly sediment on the surface. Photographs show sandy areas typically have scattered burrows, shells, amphipod communities, and worm tubes. Boulders and cobbles are commonly overgrown with hydrozoans and anemones.

    Full Text Available Im neueren Denken Judith Butlers nimmt der Begriff der Vulnerabilität eine Schlüsselrolle ein. Kaum eines der vielen Themen, denen sich die US-amerikanische Autorin seit der Jahrtausendwende widmet, kann ohne Kenntnis ihrer Überlegungen zu diesem Terminus angemessen verstanden werden. Der Versuch einer Rekonstruktion ihrer Konzeption von Vulnerabilität steht allerdings vor der Schwierigkeit, dass Butlers Gedanken hierzu über zahlreiche Texte hinweg verstreut sind, wobei bisweilen unterschiedliche Aspekte betont und verschiedene Schwerpunktsetzungen vorgenommen werden. Im vorliegenden Beitrag werden Butlers vulnerabilitätstheoretische Ausführungen in gebündelter Weise dargestellt und interpretiert. Dabei wird (1 die Bedeutsamkeit von Butlers Überlegungen zur Vulnerabilität für ihre Vorstellung von Körperlichkeit aufgewiesen, (2 der Zusammenhang von Vulnerabilität und Anerkennung erläutert und (3 gezeigt, welche ethischen Erwägungen Butler ausgehend von ihrer Anerkennungskonzeption und ihrem Denken der Vulnerabilität anstellt und inwiefern Vulnerabilität und politische Handlungsfähigkeit einander nicht ausschließen. Abschließend wird (4 Butlers Vulnerabilitätsverständnis mit einigen kritischen Rückfragen konfrontiert.

    Fatty liver and non-alcoholic steatohepatitis are frequently associated with obesity. Weight loss is the mainstay of therapy for these conditions. In this case report, we used a modification of the Dixon method to demonstrate normalization of hepatic fat content in an obese individual with fatty liver following weight reduction. This technique involves fast gradient echo instead of spin echo, which has been utilized previously, as the former provides an accurate and more rapid means of assessing hepatic fat content. This technique is recommended for the assessment of hepatic steatosis in at-risk subjects. (orig.)

    In the absence of CT or traditional transmission sources in combined clinical positron emission tomography/magnetic resonance (PET/MR) systems, MR images are used for MR-based attenuation correction (MR-AC). The susceptibility effects due to metal implants challenge MR-AC in the neck region of patients with dental implants. The purpose of this study was to assess the frequency and magnitude of subsequent PET image distortions following MR-AC. A total of 148 PET/MR patients with clear visual signal voids on the attenuation map in the dental region were included in this study. Patients were injected with [{sup 18}F]-FDG, [{sup 11}C]-PiB, [{sup 18}F]-FET, or [{sup 64}Cu]-DOTATATE. The PET/MR data were acquired over a single-bed position of 25.8 cm covering the head and neck. MR-AC was based on either standard MR-AC{sub DIXON} or MR-AC{sub INPAINTED} where the susceptibility-induced signal voids were substituted with soft tissue information. Our inpainting algorithm delineates the outer contour of signal voids breaching the anatomical volume using the non-attenuation-corrected PET image and classifies the inner air regions based on an aligned template of likely dental artifact areas. The reconstructed PET images were evaluated visually and quantitatively using regions of interests in reference regions. The volume of the artifacts and the computed relative differences in mean and max standardized uptake value (SUV) between the two PET images are reported. The MR-based volume of the susceptibility-induced signal voids on the MR-AC attenuation maps was between 1.6 and 520.8 mL. The corresponding/resulting bias of the reconstructed tracer distribution was localized mainly in the area of the signal void. The mean and maximum SUVs averaged across all patients increased after inpainting by 52% (± 11%) and 28% (± 11%), respectively, in the corrected region. SUV underestimation decreased with the distance to the signal void and correlated with the volume of the susceptibility

    To evaluate the automated two-point Dixon screening sequence for the detection and estimated quantification of hepatic iron and fat compared with standard sequences as a reference. One hundred and two patients with suspected diffuse liver disease were included in this prospective study. The following MRI protocol was used: 3D-T1-weighted opposed- and in-phase gradient echo with two-point Dixon reconstruction and dual-ratio signal discrimination algorithm (''screening'' sequence); fat-saturated, multi-gradient-echo sequence with 12 echoes; gradient-echo T1 FLASH opposed- and in-phase. Bland-Altman plots were generated and correlation coefficients were calculated to compare the sequences. The screening sequence diagnosed fat in 33, iron in 35 and a combination of both in 4 patients. Correlation between R2* values of the screening sequence and the standard relaxometry was excellent (r = 0.988). A slightly lower correlation (r = 0.978) was found between the fat fraction of the screening sequence and the standard sequence. Bland-Altman revealed systematically lower R2* values obtained from the screening sequence and higher fat fraction values obtained with the standard sequence with a rather high variability in agreement. The screening sequence is a promising method with fast diagnosis of the predominant liver disease. It is capable of estimating the amount of hepatic fat and iron comparable to standard methods.

    Full Text Available In this article I propose to study the interpretation of Butler around dialectics between master and slave. I recognize two original points in her research: the place of the body in Hegel’s philosophy and the role of the unfortunate consciousness. On the other hand, I would like to criticize the link that Butler proposes between the structure of subjection in Hegel and the notion of subjection in Foucault’s writings. I will take distance from Butler’s interpretation, since I prefer to explore a different relationship between both thinkers. Finally, I incorporate the works of Malabou, when she discusses with Butler about the place of the body in Hegel’s philosophy.

    Full Text Available El enfoque interpretativo de la visión social de la bibliotecóloga mexicana Judith Licea se articuló en tres esferas: 1. bibliotecas y sociedad excluyente, 2. bibliotecas y sociedad incluyente, 3. bibliotecas y sociedad plural. Mediante dos esquemas que van de lo general a lo particular, se configuró el pensamiento de Judith Licea en torno a esas tres dimensiones. Este análisis concluye que la óptica social bibliotecológica de la autora hace posible tejer una serie de categorías asociadas a lo que hoy se denomina bibliotecología social; asimismo, que la idea homogénea en la esfera de la gestión de servicios bibliotecarios y de información debe quedar atrás para dar paso a la idea diferenciada. También se desprende del estudio que los profesionales de la biblioteca tienen un gran reto en los procesos formales, informales y continuos de enseñanza-aprendizaje.

    Purpose: To develop an image processing method for MRI-based generation of electron density maps, known as pseudo-CT (pCT), without usage of model- or atlas-based segmentation, and to evaluate the method in the pelvic and head-neck region against CT. Methods: CT and MRI scans were obtained from the pelvic region of four patients in supine position using a flat table top only for CT. Stratified CT maps were generated by classifying each voxel based on HU ranges into one of four classes: air, adipose tissue, soft tissue or bone.A hierarchical region-selective algorithm, based on automatic thresholding and clustering, was used to classify tissues from MR Dixon reconstructed fat, In-Phase (IP) and Opposed-Phase (OP) images. First, a body mask was obtained by thresholding the IP image. Subsequently, an automatic threshold on the Dixon fat image differentiated soft and adipose tissue. K-means clustering on IP and OP images resulted in a mask that, via a connected neighborhood analysis, allowing the user to select the components corresponding to bone structures.The pCT was estimated through assignment of bulk HU to the tissue classes. Bone-only Digital Reconstructed Radiographs (DRR) were generated as well. The pCT images were rigidly registered to the stratified CT to allow a volumetric and voxelwise comparison. Moreover, pCTs were also calculated within the head-neck region in two volunteers using the same pipeline. Results: The volumetric comparison resulted in differences <1% for each tissue class. A voxelwise comparison showed a good classification, ranging from 64% to 98%. The primary misclassified classes were adipose/soft tissue and bone/soft tissue. As the patients have been imaged on different table tops, part of the misclassification error can be explained by misregistration. Conclusion: The proposed approach does not rely on an anatomy model providing the flexibility to successfully generate the pCT in two different body sites. This research is founded by Zon

    Purpose: To simulate and optimize a MR protocol for squamous cell cancer of the head and neck (HNSCC) patients for potential future use in an integrated whole-body MR–PET scanner. Materials and methods: On a clinical 3T scanner, which is the basis for a recently introduced fully integrated whole-body MR–PET, 20 patients with untreated HNSCC routinely staged with 18F-FDG PET/CT underwent a dedicated MR protocol for the neck. Moreover, a whole-body Dixon MR-sequence was applied, which is used for attenuation correction on a recently introduced hybrid MR–PET scanner. In a subset of patients volume-interpolated-breathhold (VIBE) T1w-sequences for lungs and liver were added. Total imaging time was analyzed for both groups. The quality of the delineation of the primary tumor (scale 0–3) and the presence or absence of lymph node metastases (scale 1–5) was evaluated for CT, MR, PET/CT and a combination of MR and PET to ensure that the MR–PET fusion does not cause a loss of diagnostic capability. PET was used to identify distant metastases. The PET dataset for simulated MR/PET was based on a segmentation of the CT data into 4 classes according to the approach of the Dixon MR-sequence for MR–PET. Standard of reference was histopathology in 19 cases. In one case no histopathological confirmation of a primary tumor could be achieved. Results: Mean imaging time was 35:17 min (range: 31:08–42:42 min) for the protocol including sequences for local staging and attenuation correction and 44:17 min (range: 35:44–54:58) for the extended protocol. Although not statistically significant a combination of MR and PET performed better in the delineation of the primary tumor (mean 2.20) compared to CT (mean 1.40), MR (1.95) and PET/CT (2.15) especially in patients with dental implants. PET/CT and combining MR and PET performed slightly better than CT and MR for the assessment of lymph node metastases. Two patients with distant metastases were only identified by PET

    To evaluate and compare conventional T1-weighted 2D turbo spin echo (TSE), T1-weighted 3D volumetric interpolated breath-hold examination (VIBE), and two-point 3D Dixon-VIBE sequences for automatic segmentation of visceral adipose tissue (VAT) volume at 3 Tesla by measuring and compensating for errors arising from intensity nonuniformity (INU) and partial volume effects (PVE). The body trunks of 28 volunteers with body mass index values ranging from 18 to 41.2 kg/m(2) (30.02 ± 6.63 kg/m(2)) were scanned at 3 Tesla using three imaging techniques. Automatic methods were applied to reduce INU and PVE and to segment VAT. The automatically segmented VAT volumes obtained from all acquisitions were then statistically and objectively evaluated against the manually segmented (reference) VAT volumes. Comparing the reference volumes with the VAT volumes automatically segmented over the uncorrected images showed that INU led to an average relative volume difference of -59.22 ± 11.59, 2.21 ± 47.04, and -43.05 ± 5.01 % for the TSE, VIBE, and Dixon images, respectively, while PVE led to average differences of -34.85 ± 19.85, -15.13 ± 11.04, and -33.79 ± 20.38 %. After signal correction, differences of -2.72 ± 6.60, 34.02 ± 36.99, and -2.23 ± 7.58 % were obtained between the reference and the automatically segmented volumes. A paired-sample two-tailed t test revealed no significant difference between the reference and automatically segmented VAT volumes of the corrected TSE (p = 0.614) and Dixon (p = 0.969) images, but showed a significant VAT overestimation using the corrected VIBE images. Under similar imaging conditions and spatial resolution, automatically segmented VAT volumes obtained from the corrected TSE and Dixon images agreed with each other and with the reference volumes. These results demonstrate the efficacy of the signal correction methods and the similar accuracy of TSE and Dixon imaging for automatic volumetry of VAT at 3 Tesla.

    In patients with rotator cuff tears, muscle degeneration is known to be a predictor of irreparable tears and poor outcomes after surgical repair. Fatty infiltration and volume of the whole muscles constituting the rotator cuff were quantitatively assessed using 3-dimensional 2-point Dixon magnetic resonance imaging. Ten shoulders with a partial-thickness tear, 10 shoulders with an isolated supraspinatus tear, and 10 shoulders with a massive tear involving supraspinatus and infraspinatus were compared with 10 control shoulders after matching age and sex. With segmentation of muscle boundaries, the fat fraction value and the volume of the whole rotator cuff muscles were computed. After reliabilities were determined, differences in fat fraction, muscle volume, and fat-free muscle volume were evaluated. Intra-rater and inter-rater reliabilities were regarded as excellent for fat fraction and muscle volume. Tendon rupture adversely increased the fat fraction value of the respective rotator cuff muscle (P tear group, muscle volume was significantly decreased in the infraspinatus (P = .035) and increased in the teres minor (P = .039). With subtraction of fat volume, a significant decrease of fat-free volume of the supraspinatus muscle became apparent with a massive tear (P = .003). Three-dimensional measurement could evaluate fatty infiltration and muscular volume with excellent reliabilities. The present study showed that chronic rupture of the tendon adversely increases the fat fraction of the respective muscle and indicates that the residual capacity of the rotator cuff muscles might be overestimated in patients with severe fatty infiltration.

    To develop and evaluate a novel 2D phase-unwrapping method that works robustly in the presence of severe noise, rapid phase changes, and disconnected regions. The MR phase map usually varies rapidly in regions adjacent to wraps. In contrast, the phasors can vary slowly, especially in regions distant from tissue boundaries. Based on this observation, this paper develops a phase-unwrapping method by using a pixel clustering and local surface fitting (CLOSE) approach to exploit different local variation characteristics between the phase and phasor data. The CLOSE approach classifies pixels into easy-to-unwrap blocks and difficult-to-unwrap residual pixels first, and then sequentially performs intrablock, interblock, and residual-pixel phase unwrapping by a region-growing surface-fitting method. The CLOSE method was evaluated on simulation and in vivo water-fat Dixon data, and was compared with phase region expanding labeler for unwrapping discrete estimates (PRELUDE). In the simulation experiment, the mean error ratio by CLOSE was less than 1.50%, even in areas with signal-to-noise ratio equal to 0.5, phase changes larger than π, and disconnected regions. For 350 in vivo knee and ankle images, the water-fat swap ratio of CLOSE was 4.29%, whereas that of PRELUDE was 25.71%. The CLOSE approach can correctly unwrap phase with high robustness, and benefit MRI applications that require phase unwrapping.

    2014-12-01

    Full Text Available The following article intends to approach some aspects of bourdiean thoughts in order to develop an approach to the notion of gender and the way in which – within an androcentric symbolic order and a normative heterosexual matrix – function these diagrams in the way gender makes up the subjective corporal form. From those notions, we want to reflect about the emergency of sexual identities that transgress the cultural precepts around gender founded in doxic experience. Likewise, we will sketch a brief reference among inconscient dimension across psychoanalytical tradition and performative theory across Judith Butler in the feminists debates.Through this conceptual framework we will attempt to examine how may the dominant representations of femininity, androcentric and heterosexually regulated, influence the identity formation of a feminine transsexual person, founded in the morphological ideal which has sustenance in the man-woman dichotomy, leaving the questioning open about the ways that the transgressive assumption of sex of what appears like the order of things may take in a binomic gender matrix, examining the reception of this debates in te Gender Identity Law N° 26.743

    Full Text Available El presente trabajo rescata una de las líneas teóricas puestas en consideración en la mesa temática Problemas de Género durante el 9º Congreso Argentino y 4ºLatinoamericano de Educación Física y Ciencias. A partir de aquellos trabajos que referenciaron a Judith Butler en sus desarrollos, con el fin de cuestionar los criterios naturalizados con los que se clasifican los cuerpos, se intentan ampliar y profundizar las reflexiones de algunos expositores. Para tal fin, se exponen los interrogantes que emergieron en el interior de los debates sobre este punto, al tiempo que se enfatizan las líneas argumentativas utilizadas en algunas de las ponencias que dan cuenta de modos alternativos de pensar al cuerpo más allá de explicaciones esencialistas. Finalmente, se retoman algunas reflexiones llevadas a cabo en el debate posterior a la lectura de los trabajos que focalizaron el lugar de las prácticas de la educación física como reproductora y transformadora, al mismo tiempo, de las normas de género y sexualidad

  6. The pendulum is never static: Jesus Sira to Jesus Christ on women in the light of Judith, Susanna and LXX Esther

    2009-09-01

    Full Text Available When the New Testament is interpreted, directly preceding literature is largely neglected. The dialectical terms, discourse and contra-discourse do not often surface in research on this period. This is especially the case with reference to women. Jesus Ben Sira (ca. 196 BCE as well as other wisdom writers had quite a negative view of women. Although it has previously been argued that this negative discourse on women was challenged by Judith, this article goes further: the Additions to Esther and Susanna are added as possible challenging discourses. It is argued that these texts convincingly confront Ben Sira’s negative views and add substantial value to the worth and status of women. During the CE, both Jesus Christ and the Apostle Paul had a mainly positive view of women. Positive ideas and allusions from texts are pointed out that might have their roots in the Apocrypha. Lastly, this article argues that the disputed Pauline letters contain a swing back towards Jesus Ben Sira’s negative view of women.

    To assess the feasibility of T2{sup *}-corrected fat-signal fraction (FF) map by using the three-echo volume interpolated breath-hold gradient echo (VIBE) Dixon sequence to differentiate between malignant marrow-replacing lesions and benign red marrow deposition of vertebrae. We assessed 32 lesions from 32 patients who underwent magnetic resonance imaging after being referred for assessment of a known or possible vertebral marrow abnormality. The lesions were divided into 21 malignant marrow-replacing lesions and 11 benign red marrow depositions. Three sequences for the parameter measurements were obtained by using a 1.5-T MR imaging scanner as follows: three-echo VIBE Dixon sequence for FF; conventional T1-weighted imaging for the lesion-disc ratio (LDR); pre- and post-gadolinium enhanced fat-suppressed T1-weighted images for the contrast-enhancement ratio (CER). A region of interest was drawn for each lesion for parameter measurements. The areas under the curve (AUC) of the parameters and their sensitivities and specificities at the most ideal cutoff values from receiver operating characteristic curve analysis were obtained. AUC, sensitivity, and specificity were respectively compared between FF and CER. The AUCs of FF, LDR, and CER were 0.96, 0.80, and 0.72, respectively. In the comparison of diagnostic performance between the FF and CER, the FF showed a significantly larger AUC as compared to the CER (p = 0.030), although the difference of sensitivity (p = 0.157) and specificity (p = 0.157) were not significant. Fat-signal fraction measurement using T2{sup *}-corrected three-echo VIBE Dixon sequence is feasible and has a more accurate diagnostic performance, than the CER, in distinguishing benign red marrow deposition from malignant bone marrow-replacing lesions.

    To evaluate the diagnostic value of T2{sup *} mapping using 3D multi-echo Dixon gradient echo acquisition on gadoxetic acid-enhanced liver magnetic resonance imaging (MRI) as a tool to evaluate hepatic function. This retrospective study was approved by the IRB and the requirement of informed consent was waived. 242 patients who underwent liver MRIs, including 3D multi-echo Dixon fast gradient-recalled echo (GRE) sequence at 3T, before and after administration of gadoxetic acid, were included. Based on clinico-laboratory manifestation, the patients were classified as having normal liver function (NLF, n = 50), mild liver damage (MLD, n = 143), or severe liver damage (SLD, n = 30). The 3D multi-echo Dixon GRE sequence was obtained before, and 10 minutes after, gadoxetic acid administration. Pre- and post-contrast T2{sup *} values, as well as T2{sup *} reduction rates, were measured from T2{sup *} maps, and compared among the three groups. There was a significant difference in T2{sup *} reduction rates between the NLF and SLD groups (−0.2 ± 4.9% vs. 5.0 ± 6.9%, p = 0.002), and between the MLD and SLD groups (3.2 ± 6.0% vs. 5.0 ± 6.9%, p = 0.003). However, there was no significant difference in both the pre- and post-contrast T2{sup *} values among different liver function groups (p = 0.735 and 0.131, respectively). A receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve for using T2{sup *} reduction rates to differentiate the SLD group from the NLF group was 0.74 (95% confidence interval: 0.63–0.83). Incorporation of T2{sup *} mapping using 3D multi-echo Dixon GRE sequence in gadoxetic acid-enhanced liver MRI protocol may provide supplemental information for liver function deterioration in patients with SLD.

    Highlights: • We examined the influence of different clinically used contrast agents on the image quality of a new sequence called CDT-VIBE for dynamic MRI of the liver. • CDT-VIBE is a robust sequence for clinical routine as it provides good image quality regardless of the utilized contrast agent. • In average, more than 3 hepatic arterial dominant phases are acquired with the CDT-VIBE sequence regardless of the contrast agent. - Abstract: Purpose: CAIPIRINHA-Dixon-TWIST (CDT)-VIBE is a robust method for abdominal magnetic resonance imaging providing both high spatial and high temporal resolution. The purpose of this study was to examine the influence of different gadolinium based contrast agents (GBCA) on image quality (IQ) with CDT-VIBE. Materials and methods: In this IRB-approved, retrospective, inter-individual comparison study, 86 patients scanned at 3T were included. Within 28 s, 14 high-resolution 3D datasets were acquired using CDT-VIBE. 37 patients received 0.1 mmol/kg gadoterate meglumine, 28 patients 0.1 mmol/kg gadobutrol, and 19 patients 0.1 mL/kg gadoxetic acid. Two blinded, board-certified radiologists assessed the image quality on a 5 point scale, as well as the number of hepatic arterial dominant (HAD) phases. Results: Regardless of the GBCA utilized, CDT-VIBE resulted in good IQ in terms of best IQ achieved among all 14 datasets (gadobutrol 4.3, gadoterate meglumine 3.9, gadoxetic acid 3.7). With respect to worst IQ, the three groups showed statistically significant differences with gadobutrol receiving the highest rating (3.6) and gadoxetic acid the lowest (2.4) (gadoterate meglumine 3.0; 0.0014 < p < 0.0485). No statistically significant differences were found in the mean number of acquired HAD phases (gadobutrol 3.4, gadoterate meglumine 3.9, gadoxetic acid 3.1; 0.18 < p < 0.57). Conclusion: Different gadolinium-based contrast agents can be utilized for dynamic liver imaging with CDT-VIBE resulting in good image quality.

    Quantitative PET image reconstruction requires an accurate map of attenuation coefficients of the tissue under investigation at 511 keV (μ-map), and in order to correct the emission data for attenuation. The use of MRI-based attenuation correction (MRAC) has recently received lots of attention in the scientific literature. One of the major difficulties facing MRAC has been observed in the areas where bone and air collide, e.g. ethmoidal sinuses in the head area. Bone is intrinsically not detectable by conventional MRI, making it difficult to distinguish air from bone. Therefore, development of more versatile MR sequences to label the bone structure, e.g. ultra-short echo-time (UTE) sequences, certainly plays a significant role in novel methodological developments. However, long acquisition time and complexity of UTE sequences limit its clinical applications. To overcome this problem, we developed a novel combination of Short-TE (ShTE) pulse sequence to detect bone signal with a 2-point Dixon technique for water–fat discrimination, along with a robust image segmentation method based on fuzzy clustering C-means (FCM) to segment the head area into four classes of air, bone, soft tissue and adipose tissue. The imaging protocol was set on a clinical 3 T Tim Trio and also 1.5 T Avanto (Siemens Medical Solution, Erlangen, Germany) employing a triple echo time pulse sequence in the head area. The acquisition parameters were as follows: TE1/TE2/TE3=0.98/4.925/6.155 ms, TR=8 ms, FA=25 on the 3 T system, and TE1/TE2/TE3=1.1/2.38/4.76 ms, TR=16 ms, FA=18 for the 1.5 T system. The second and third echo-times belonged to the Dixon decomposition to distinguish soft and adipose tissues. To quantify accuracy, sensitivity and specificity of the bone segmentation algorithm, resulting classes of MR-based segmented bone were compared with the manual segmented one by our expert neuro-radiologist. Results for both 3 T and 1.5 T systems show that bone segmentation applied in several

    Purpose To determine the degree of preoperative fatty degeneration within muscles, postoperative longitudinal changes in fatty degeneration, and differences in fatty degeneration between patients with full-thickness supraspinatus tears who do and those who do not experience a retear after surgery. Materials and Methods This prospective study had institutional review board approval and was conducted in accordance with the Committee for Human Research. Informed consent was obtained. Fifty patients with full-thickness supraspinatus tears (18 men, 32 women; mean age, 67.0 years ± 8.0; age range, 41-91 years) were recruited. The degrees of preoperative and postoperative fatty degeneration were quantified by using a two-point Dixon magnetic resonance (MR) imaging sequence; two radiologists measured the mean signal intensity on in-phase [S(In)] and fat [S(Fat)] images. Estimates of fatty degeneration were calculated with "fat fraction" values by using the formula S(Fat)/S(In) within the supraspinatus, infraspinatus, and subscapularis muscles at baseline preoperative and at postoperative 1-year follow-up MR imaging. Preoperative fat fractions in the failed-repair group and the intact-repair group were compared by using the Mann-Whitney U test. Results The preoperative fat fractions in the supraspinatus muscle were significantly higher in the failed-repair group than in the intact-repair group (37.0% vs 19.5%, P muscle tended to progress at 1 year postoperatively in only the failed-repair group. Conclusion MR imaging quantification of preoperative fat fractions by using a two-point Dixon sequence within the rotator cuff muscles may be a viable method for predicting postoperative retear.

    Full Text Available In ihrer sehr gut strukturierten Arbeit über gegenwärtige sowie zukünftig neu zu schaffende famlienfördernde Leistungen im Sozialrecht gibt Judith Will einen ausführlichen und weitgehend vollständigen Überblick über sämtliche wesentlichen Sozialleistungen zur Familienförderung. Will untersucht außerdem eine Reihe von Reformansätzen und Lösungsmodellen, mit welchen den bestehenden Defiziten begegnet werden soll, und neigt dabei zu einer Lösung, welche auf den Ausbau von Dienstleistungen für Familien setzt, z. B. durch Ausbau und qualitative Verbesserung öffentlicher Kinderbetreuung in Kindergärten, Krippen und Horten. Dies trage auch zu verbesserten Erwerbschancen für Frauen sowie zur Vermeidung von Familienarmut bei.In her very well structured work of social justice on the existing benefits intended to support families as well as those to be created in the future, Judith Will offers a comprehensive and (for the most part complete overview of all the essential social benefits needed for family support. Will examines, moreover, a series of proposals for reform and solution models, with which the existing deficits should be approached. She leans toward a solution that banks on the expansion of family services, for example through the qualitative improvement of public childcare in kindergartens, day cares, and after school care. This would also significantly better the earning chances for women and help to avoid family poverty.

    The purpose of this study was to assess the feasibility and image quality of a novel, highly accelerated T1-weighted sequence for time-resolved imaging of the abdomen during the first pass of contrast media transit using controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA) under sampling, view-sharing techniques, and Dixon water-fat separation (CAIPRINHA-Dixon-time-resolved imaging with interleaved stochastic trajectories-volumetric interpolated breath-hold examination [CDT-VIBE]). In this retrospective, institutional review board-approved study, 47 patients (median age, 62 years; 25 men, 22 women) scanned on a 3.0-T magnetic resonance system (Skyra; Siemens) were included. The CDT-VIBE (repetition time/echo time1/echo time2, 4.1/1.33/2.56 milliseconds; acquisition time, 29 seconds) was used in place of the standard arterial phase acquisition and started 15 seconds after the injection of 0.1 mmol/kg Gd-DOTA (Dotarem, Guerbet). Within 29 seconds, 14 high spatial resolution (1.2 × 1.2 × 3 mm) 3-dimensional data sets were acquired and reconstructed using view sharing (temporal resolution, 2.1 seconds). The CDT-VIBE images were evaluated independently by 2 blinded, experienced radiologists with regard to image quality and the number of hepatic arterial-dominant phases present on an ordinal 5-point scale (5, excellent; 1, nondiagnostic). Added diagnostic information with CDT-VIBE relative to portal venous phase VIBE was assessed. In all patients, CDT-VIBE measurements were successfully acquired. The image quality was diagnostic in 46 of the 47 patients. Both readers assessed the highest image quality present in the data sets with a median score of 4 (range, 3-5 for both readers; κ, 0.789) and the worst image quality with a median score of 3 (range, 1-4 for both readers; κ, 0.689). With a range between 1 and 8 (median, 5), hepatic arterial-dominant data sets (of the 14 acquired) were obtained in each case. There was an added diagnostic

    2013-11-01

    Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

    2015-11-01

    Full Text Available In the paper that follows, I propose myself to tense a series of theoretical discussions on what each one of them understand by subjetification processes, in a social and political key. With that purpose in mind, I organize the writing into two sections. The first one will discuss the processes of subjective setting-up from the perspective of Slavoj Zizek taking his dialogue with the lacanian psychoanalysis, thinking on its approaches on the renewed spot of the subject in the postestructuralist frame. In a second moment, I will continue with the proposals of Judith Butler and Ernesto Laclau, taking Jacques Rancière as a counterpoint with the aim of resituate the point on the subjetification process as a political commitment. The main goal I am pursuing with this critique relies on reflecting, on the one hand, on the strictly political character that some authors give to the subjetive constitution process itself, while, on the other hand, I am interested on the possible divergences on those that examine the process in a mayor and more complex frame, related to the constitution of the social. The starting point of this reflections is found on the differences that a myriad of authors compromised with a posfundacional view have proposed between the political and the politics, and on the spot of the subject on that arena.

    2002-11-01

    Full Text Available Este artículo pretende constituir una aproximación desde la Psicología Social a la teoría de la performatividad de género de Judith Butler. Si bien dentro del pensamiento feminista contemporáneo se ha venido asociando la categoría "sexo" al ámbito de lo natural y la categoría "género" a la dimensión cultural y socialmente construida de las categorías asociadas al sexo (siendo presentados ambos términos como un par de opuestos, Butler efectúa en su obra una deconstrucción de dicha dicotomía, mostrando como el sexo es ya de por sí una construcción social que, por tanto, ha sido género todo el tiempo. En este texto también se intenta indagar en la aportación que la teoría de performatividad puede suponer para una teoría de la subjetividad en psicología social; para ello resulta fundamental la defensa que Butler hace de la aparentemente paradójica posibilidad de transformación social a partir de las categorías sociales que, a la vez que nos conforman como sujetos, nos están subordinando.

    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

    Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was used to determine rare earth element (REE) content of 76 fossil bones collected from the Upper Cretaceous (Campanian) Two Medicine (TMF) and Judith River (JRF) Formations of Montana. REE content is distinctive at the formation scale, with TMF samples exhibiting generally higher overall REE content and greater variability in REE enrichment than JRF samples. Moreover, JRF bones exhibit relative enrichment in heavy REE, whereas TMF bones span heavy and light enrichment fields in roughly equal proportions. TMF bones are also characterized by more negative Ce anomalies and greater U enrichment than JRF bones, which is consistent with more oxidizing diagenetic conditions in the TMF. Bonebeds in both formations show general consistency in REE content, with no indication of spatial or temporal mixing within sites. Previous studies, however, suggest that the bonebeds in question are attritional assemblages that accumulated over considerable time spans. The absence of geochemical evidence for mixing is consistent with diagenesis transpiring in settings that remained chemically and hydrologically stable during recrystallization. Lithology-related patterns in REE content were also compared, and TMF bones recovered from fluvial sandstones show relative enrichment in heavy REE when compared with bones recovered from fine-grained floodplain deposits. In contrast, JRF bones, regardless of lithologic context (sandstone versus mudstone), exhibit similar patterns of REE uptake. This result is consistent with previous reconstructions that suggest that channel-hosted microfossil bonebeds of the JRF developed via the reworking of preexisting concentrations embedded in the interfluve. Geochemical data further indicate that reworked elements were potentially delivered to channels in a recrystallized condition, which is consistent with rapid adsorption of REE postmortem.

    Full Text Available Körperlichkeit und Geschlechterrollen sind jene Themen, die im öffentlichen Diskurs um Religion, vor allem um die drei monotheistischen Religionen, am meisten kontrovers diskutiert werden. Wie sehr der weibliche Körper in der Auseinandersetzung mit Fragen von Macht und Amt, ‚Reinheit‘ und ‚Unreinheit‘, aber auch für das Gottesbild und das Sprechen über Gott eine Rolle spielt, zeigt der vorgestellte Sammelband. Die Autorinnen sind Angehörige des Judentums, Christentums und Islams und geben zu den genannten Themen ihre Perspektive wieder, gehen aber auch auf die jeweils anderen Blickwinkel ein, so dass sich ein überraschend vielschichtiges Bild ergibt. Das Buch stellt einen hochinteressanten Beitrag zur aktuellen Debatte um Religion, Geschlecht und Gesellschaft dar.Corporeality and gender roles are those themes that are most controversial in public discourse on religion, especially in the three monotheistic religions. The collected volume introduced here shows how the female body plays an extensive role in the discussion over questions of power and office, “purity” and “impurity,” but also on the image of God and talking about God. The authors each practice Judaism, Christianity, and Islam and express their individual perspectives on the themes mentioned. They each also respond to the other perspectives. The result is a surprisingly multilayered image. The book represents a very interesting contribution to the current debate on religion, gender, and society.

  6. The Submission and Resistance of the Subject---A Preliminary Study on Judith Butler’s Power Theory%主体的屈服与反抗--朱迪斯·巴特勒权力理论初探

    王玉珏

    2016-01-01

    Through the analysis of the theory of Hegel, Nietzsche, Freud and Althusser, Judith But-ler points out a way of theoretical reflection on subjective self-sufficiency. The subject may submit to pow-er, while taking shape and acquiring dynamism at the same time. For Butler, to theorize subjection re-quires a psychoanalytic theory of the constitution of the subject. The spiritual world of the subject is de-termined by the power operation of the social world. But identification of the subject to power may not al-ways be realized, which implies some kind of resistance. In a sense, Butler’s research is not traditional e-mancipatory politics but the politics of recognition.%美国著名哲学家朱迪斯·巴特勒通过对黑格尔、尼采、弗洛伊德和阿尔都塞的理论的分析,指认出一条反思主体自足性的理论路径,其表明个体对权力的服从既是向权力屈从的过程,同时也是主体得以形成并获得能动性的条件。巴特勒试图从精神分析的角度去探究主体在精神方面获得建构的过程,指出主体的精神世界是由社会世界的权力运作决定的,自我在形成过程中内化了特定的社会规训。但主体对权力的认同未必总能实现,其中蕴含着某种反抗的可能。可以说,巴特勒的研究不再是传统意义上的解放政治,而是一种承认的政治、服从的政治。

    2016-01-01

    Group discussions are essential for organizing every aspect of modern life, from faculty meetings to senate debates, from grant review panels to papal conclaves. While costly in terms of time and organization effort, group discussions are commonly seen as a way of reaching better decisions compared to solutions that do not require coordination between the individuals (e.g. voting)---through discussion, the sum becomes greater than the parts. However, this assumption is not irrefutable: anecdotal evidence of wasteful discussions abounds, and in our own experiments we find that over 30% of discussions are unproductive. We propose a framework for analyzing conversational dynamics in order to determine whether a given task-oriented discussion is worth having or not. We exploit conversational patterns reflecting the flow of ideas and the balance between the participants, as well as their linguistic choices. We apply this framework to conversations naturally occurring in an online collaborative world exploration ga...

    Various alternative methods are being used in many medical colleges to reinforce didactic lectures in physiology. Small group teaching can take on a variety of different tasks such as problem-solving, role play, discussions, brainstorming, and debate. Research has demonstrated that group discussion promotes greater synthesis and retention of materials. The aims of this study were to adopt a problem-solving approach by relating basic sciences with the clinical scenario through self-learning. To develop soft skills, to understand principles of group dynamics, and adopt a new teaching learning methodology. Experimental study design was conducted in Phase I 1(st) year medical students of 2014-2015 batch (n = 120). On the day of the session, the students were grouped into small groups (15 each). The session started with the facilitator starting off the discussion. Feedback forms from five students in each group was taken (n = 40). A five point Likert scale was used ranging from strongly agree to strongly disagree. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Our results show that 70% of the students opined that small group discussion were interactive, friendly, innovative, built interaction between teacher and student. Small group discussion increased their thought process and helped them in better communication. The small group discussion was interactive, friendly, and bridged the gap between the teacher and student. The student's communication skills are also improved. In conclusion, small group discussion is more effective than the traditional teaching methods.

    For Socrates, as he appears in Plato's dialogues, the process of discussion is essential for preparing human beings to lead a moral life. Only through discussion, Socrates maintains, can we be led to an understanding of such concepts as wisdom, courage and justice. The author of this article believes that the Socratic notion of the moral value of discussion is still valid. In support of this view, he examines two recent works: Dialogues on Moral Education by John Wilson and Barbara Cowell, and Moral Education, Secular and Religious by John L. Elias. Finally, the author suggests how the Socratic concept of dialogue might be used in moral education today.

    Groups of individuals can sometimes make more accurate judgments than the average individual could make alone. We tested whether this group advantage extends to lie detection, an exceptionally challenging judgment with accuracy rates rarely exceeding chance. In four experiments, we find that groups are consistently more accurate than individuals in distinguishing truths from lies, an effect that comes primarily from an increased ability to correctly identify when a person is lying. These experiments demonstrate that the group advantage in lie detection comes through the process of group discussion, and is not a product of aggregating individual opinions (a "wisdom-of-crowds" effect) or of altering response biases (such as reducing the "truth bias"). Interventions to improve lie detection typically focus on improving individual judgment, a costly and generally ineffective endeavor. Our findings suggest a cheap and simple synergistic approach of enabling group discussion before rendering a judgment.

    Creating discussion boards (DBs) that capture student imaginations and contain meaningful interactions can be a difficult process. Traditional DBs use a question-and-answer format that often is boring for both the student and instructor. The authors present creative approaches to DBs that result in lively debates and student-to-student and student-to-faculty interactions, including role playing, blogging, wikis, and the use of voice.

    A classic paper in intellect and argument, this article contains a transcript of a conversation between Jay Haley, John Weakland, and Milton Erickson as they discuss the role of communication in hypnosis and schizophrenia. In 1955, schizophrenia was considered primarily a psychological disorder. Whereas today schizophrenia is mostly considered a biological disorder, this very early, unpublished paper still gives much food for thought and a further glimpse into Haley and Erickson's thinking and intellect at a fervent time in schizophrenia research.

    The Arctic vortex is a persistent large-scale cyclonic circulation in the middle and upper troposphere and the stratosphere. Its activity and variation control the semi-permanent active centers of Pan-Arctic and the short-time cyclone activity in the subarctic areas. Its strength variation, which directly relates to the atmosphere, ocean, sea ice and ecosystem of the Arctic, can affect the lower atmospheric circulation, the weather of subarctic area and even the weather of middle latitude areas. The 2003 Chinese Second Arctic Research Expedition experienced the transition of the stratosphereic circulation from a warm anticyclone to a cold cyclone during the ending period of Arctic summertime, a typical establishing process of the polar vortex circulation. The impact of the polar vortex variation on the low-level circulation has been investigated by some scientists through studying the coupling mechanisms of the stratosphere and troposphere. The impact of the Stratospheric Sudden Warming (SFW) events on the polar vortex variation was drawing people's great attention in the fifties of the last century. The Arctic Oscillation (AO) , relating to the variation of the Arctic vortex, has been used to study the impact of the Arctic vortex on climate change. The recent Arctic vortex studies are simply reviewed and some discussions on the Arctic vertex are given in the paper. Some different views and questions are also discussed.

    Full Text Available Background: There are diverging opinions about scientific evidence for Homoeopathy, but evidence for conventional medicine is not perfect either. In fact, proof for Homoeopathy is not inferior to conventional. However, the evidence for Homoeopathy has been downplayed by selection of trials (cherry-picking. The effect of Homoeopathy in randomized controlled trials (RCTs, however, is small due to many ineffective prescriptions. This is caused by shortcomings of our Materia Medica and Repertories. Discussion: The hegemony of the RCT is increasingly questioned; it does not provide all answers, especially not for the individual patient. The individual patient wants to know his individual prognosis: Will this medicine work for him? This is even more important than his individual diagnosis. It is possible to assess prognosis scientifically the same way as diagnosis. Prognostic research is based on daily practice; practitioners should have knowledge about statistics to fulfill their role in this process. Conclusion: The discussion in this paper elucidates that RCT has its limitations, especially for the patient whose main concern is recovery/prognosis. Drug validation is a key to improve the outcome of clinical practice in Homoeopathy.

    The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

    showing the increase, considering latency and the length of the observation period. Of further interest are results relating to diseases of the urinary tract such as kidney failure in the NPCSs of Basso bacino del fiume Chienti, Taranto, Milazzo and Priolo. Overall, the results discussed above are consistent with the previous findings pertaining to mortality for 1995-2002. The present analysis also introduces a new element - the study of cancer incidence and hospital discharges - which can tell us a great deal about diseases with high survival rates or non lethal ones. The first is the case of thyroid cancer, which presents increases in both databases and for both genders in a number of NPCSs (Brescia-Caffaro, Laghi di Mantova, Milazzo, Sassuolo- Scandiano and Taranto). The study of cancer incidence and hospital discharges also revealed cancer excesses for melanoma, breast cancer and non Hodgkin lymphoma in Brescia-Caffaro NPCS where PCBs (Polychlorinated biphenyl) are the site's main pollutant. PCBs, according to the 2013 evaluation of the International Agency for Research on Cancer, are ascertained human carcinogens for melanoma and probable carcinogens for breast cancer and non-Hodgkin lymphoma. The results pertaining to cancer incidence in the 17 NPCSs can also be presented using rankings by area or disease analyzed by a multivariate hierarchical Bayesian model. These rankings reveal an overlapping of credibility intervals, such that it is not possible to speak of a limited number of cancer sites or of certain NPCSs as being particularly affected. Every NPCS, therefore, must be considered individually and ordering them by ranking of cancer incidence wouldn't be appropriate. Data collected concerning some of the NPCSs in the context of the SENTIERI Project is so conclusive that remediation measures can immediately be put in place. This is the case in the Biancavilla and Brescia-Caffaro NPCSs. A similar conclusion can be drawn for complex locations such as Taranto

    In Bodies that Matter,Judith Butler examed the material dimensions of the construction of "sex" and "body",which continued the topic of performative theory in the last book Gender Trouble.Initially,she used the power theory of Foucault to sketch the body's topography of construction.Consequently,the assumption of sex was phantasmatic identification within the psychoanalysis,although Freud and Lacan was phallocentrism.In the end,through a critical engagement with Slavoj Zizek's performative theory of names,Butler provided the resignification function of names could show us the agency of subject.%《身体之重》是美国学者朱迪斯.巴特勒继提出性别述行理论的成名作《性别麻烦》之后,继续探讨生理性别与身体在物质维度上如何述行建构这一问题的力作。一方面,她借助米歇尔.福柯的权力话语理论,对身体的物质性建构进行了考察;另一方面,她力图在精神分析理论的菲勒斯中心主义框架内揭示性别认同的幻象。通过批判齐泽克的称谓述行理论,巴特勒提出称谓的再赋义功能,认为主体在话语的掌控当中依然具有能动性。

    We led two discussion groups during the 2007 National GAP Conference. These discussion groups provided information to help develop a survey of National Gap Analysis Program (GAP) data users. One group discussed technical issues, and the second group discussed the use of GAP data for decisionmaking. Themes emerging from the technical issues group included concerns about data quality, need for information on how to use data, and passive data distribution. The decisionmaking discussion included a wide range of topics including the need to understand presentation of information, the need to connect with and understand users of data, the revision of GAP's mission, and the adaptability of products and data. The decisionmaking group also raised concerns regarding technical issues. One conclusion is that a deep commitment to ongoing information transfer and support is a key component of success for the GAP program.

  17. Chinese women's participation in fertility discussions.

    Li, L

    1993-01-01

    In an attempt to better understand the process through which the family planning (FP) programs and socioeconomic developments in China affect fertility, women's participation in fertility discussions with their husbands are examined as an intermediate factor in a study based on results of a random survey of 6654 ever-married women of reproductive age from 7 cities and 30 counties of Guangdong. First, it must be noted that Chinese couples do have individual choices (albeit quite limited ones) about their fertility; they can choose to follow or ignore government policy or they can choose to remain childless. The present study has 3 major hypotheses: 1) the more a woman is involved in fertility discussions with her husband, the fewer children she will have; 2) urban women with a higher educational status will be more likely to have such discussions; and 3) women who are contacted individually by FP personnel are more likely to be involved in fertility discussions. After a discussion of data collection and variables (number of living children, education of wife and husband, age at marriage, residence, living with parents, contacted by FP personnel, and discussion with husband), the results are presented in terms of zero-order correlation coefficients indicating their relationships. The bivariate analysis supported the hypotheses. Multiple regression analysis showed that age at marriage, education of wives and husbands, FP contacts, and participation in discussions remain significant fertility determinants (but the correlation between fertility and residence becomes trivial). A further regression model indicated that a woman's educational attainment is the most significant positive indication of their participation in fertility discussions. These results imply that as women's status continues to improve in China and the deeply-rooted patriarchal tradition loses hold, increased gender equity and education will influence a fertility decline. FP personnel could also

    Full Text Available The major aim of this study was to investigate the effect of literary discussion on critical thinking. To this end, two classes (experimental and control groups were selected from College of Ferdowsi University. In both groups literature was used as supplementary homework. Students were supposed to read short stories and poems at home and present them in class. The students in the experimental group were discussing the materials in class and the students in the control group only memorized the texts and retold them. At the end of the term, the students were asked to take a questionnaire on critical thinking. The results demonstrated that there was a significant difference between means of two groups, implying that literary discussion can enhance critical thinking. Finally, results were discussed in the context of education in Iran and some suggestions were made.

    Full Text Available Scholars have suggested models proposing a variety of learning styles for humans. Human Dynamics is one such model, and it has been suggested within its model that one style of learning is enhanced by discussion among learners. While this style of learning may be accomplished relatively easily in an on-campus person-to-person situation, it is not clear how a discussion mode (online posts of learning might be accomplished in an online format. A study of more than 9,000 posts from 240 students in 11 different online classes was conducted to determine whether differences in online discussion posts by individuals with different learning styles were evident. Results of the study suggest that discussion post activity, if managed with suitable rubrics and guiding principles, and augmented by appropriate modeling behavior, is an effective teaching mode for all dynamics, but seem to be a more successful learning mode for individuals of Physically Centered dynamics.

    Discussion of the nuclear force, lead by a round table consisting of T. Cohen, E. Epelbaum, R. Machleidt, and F. Gross (chair). After an invited talk by Machleidt, published elsewhere in these proceedings, brief remarks are made by Epelbaum, Cohen, and Gross, followed by discussion from the floor moderated by the chair. The chair asked the round table and the participants to focus on the following issues: (i) What does each approach (chiral effective field theory, large Nc, and relativistic phenomenology) contribute to our knowledge of the nuclear force? Do we need them all? Is any one transcendent? (ii) How important for applications (few body, nuclear structure, EMC effect, for example) are precise fits to the NN data below 350 MeV? How precise do these fits have to be? (iii) Can we learn anything about nonperturbative QCD from these studies of the nuclear force? The discussion presented here is based on a video recording made at the conference and transcribed afterward.

    2010-09-01

    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

    2011-07-01

    This study investigated online interaction within a curriculum unit at the University of Toronto, Canada that included an interprofessional case study discussion in a mixed-mode (face-to-face and online) format. Nine of the 81 teams that completed the four-day curriculum were selected for detailed review based on the attitudes students expressed on a survey about the value of collaborating online for enhancing their appreciation of other health care professions. Five of the teams selected were 'positive' and four were 'negative'. The responses to other survey items by members of these teams were then compared, as well as their message posting patterns and the content of their online discussions. Differences between the two sets were situated within a theoretical framework drawn from the contact theory, social interdependence theory, and the Community of Inquiry model. Institutional support in the form of facilitator involvement, individual predispositions to online and group learning, the group composition, the learning materials, task and assignment, and technical factors all affected the levels of participation online. Discourse and organizational techniques were identified that related to interactivity within the online discussions. These findings can help curriculum planners design interprofessional case studies that encourage the interactivity required for successful online discussions.

    Science.gov (United States)

    Ahn, Jae Hee; Jeon, Woo Taek

    2011-12-01

    This study aims to analyze the characteristics of discussion materials that promote student participation in discussions, satisfaction with student instruction, and tutor intervention in the medical humanities. We surveyed 117 premedical students and 7 tutors who attended 4-week group discussions in the medical humanities in 2010. We described the discussion materials using the following 4 characteristics as independent variables: material type, level of understanding, interest, and quantity. Dependent variables were: student participation in the discussion, student instruction satisfaction, and tutor intervention. Correlation analysis, multiple regression analysis, and crosstab were performed using SPSS 15.0. The correlation between the characteristics of the discussion materials differed by grade. When the books were chosen as the discussion material in the instruction of first-year premedical students, the correlation between level of understanding, interest, and quantity was negative. Higher levels of understanding of the material and interest in the material led to an increase in discussion participation among both first- and second-year premedical students. Higher levels of understanding and interest of the discussion material also increased student satisfaction with the instruction, regardless of grade. Finally, levels of understanding of the material affected the degree of tutor intervention. Tutors intervened more often in discussions with first-year premedical students than with second-year premedical students. Differences in grades and the understanding of the discussion material should be considered when choosing discussion materials. Further study is required to continue the development of the discussion model and improve methods of facilitate discussion among students in the medical humanities.

    2013-09-01

    Writing manuscripts to describe study outcomes, although not easy, is the main task of an academician. The aim of the present review is to outline the main aspects of writing the discussion section of a manuscript. Additionally, we address various issues regarding manuscripts in general. It is advisable to work on a manuscript regularly to avoid losing familiarity with the article. On principle, simple, clear and effective language should be used throughout the text. In addition, a pre-peer review process is recommended to obtain feedback on the manuscript. The discussion section can be written in 3 parts: an introductory paragraph, intermediate paragraphs and a conclusion paragraph. For intermediate paragraphs, a "divide and conquer" approach, meaning a full paragraph describing each of the study endpoints, can be used. In conclusion, academic writing is similar to other skills, and practice makes perfect.

  5. Quantum clock: A critical discussion on spacetime

    CERN Document Server

    Burderi, Luciano; Iaria, Rosario

    2016-01-01

    We critically discuss the measure of very short time intervals. By means of a Gedankenexperiment, we describe an ideal clock based on the occurrence of completely random events. Many previous thought experiments have suggested fundamental Planck-scale limits on measurements of distance and time. Here we present a new type of thought experiment, based on a different type of clock, that provide further support for the existence of such limits. We show that the minimum time interval $\\Delta t$ that this clock can measure scales as the inverse of its size $\\Delta r$. This implies an uncertainty relation between space and time: $\\Delta r$ $\\Delta t$ $> G \\hbar / c^4$; where G, $\\hbar$ and c are the gravitational constant, the reduced Planck constant, and the speed of light, respectively. We outline and briefly discuss the implications of this uncertainty conjecture.

    Full Text Available The article deals with the lack of effective ways of building relationships, parenting responsibility and conflict solving in the school community. It is addressed to the whole school community – to the administration, psychologists and social workers, to the faculty, parents and students. We discuss the key concepts and principles of “restorative culture” and the reasons for its introduction in educational institutions. The restorative culture refers to activities on formation and spread of interpersonal relations value in the aspect of its understanding, trust, acceptance of active responsibility, separation of problems and subjects, and focus on the successful experience. We briefly discuss the theory of restorative justice and narrative practice. Particular attention is paid to the typical methods of school response to conflicts, and to zero-tolerance policy. We propose that the school community needs a number of specific technologies that would optimally suit for different types of situations and would constitute a part of the system

The involvement of all the domains and the large variability of diagnoses identified suggested a possible holistic view of patient care and emphasized the individuality of the care plan. However, it may indicate an immaturity of these students, because often different diagnosis are related, and interventions set to one of these can solve the other, so opting for one avoids large health plans. Researchers and professors should conduct investigations and discussions to be identified teaching methods best suited to the teaching of the diagnostic process.

    2007-05-01

    Full Text Available In the past gender specific problems were mainly discussed in a female perspective. In the meantime there is a rising attentiveness in the living conditions of men and their coping strategies within critical life events. In this paper an appropriate frame of reference is outlined which can be used in those areas of social work where men are already discovered as a target group with special difficulties and needs.

  14. Islamophobia? The German Discussion about Islamophobia

    2009-08-01

    Full Text Available Islamophobia is a term which is relatively new in the world of social science; it is a neologism. Kofi Annan has warned about it but there is not a clear, undoubted concept to it yet – and it is questionable if there ever will be, especially if one looks into the German controversy about the term. The German discussion is not unique though, and must fall into the pattern of wider, European discussion about the Islamic minority. Prominent figures of Islamic hatred in Europe are for instance Oriana Fallaci and Brigitte Bardot. Against them, there stands a more liberal community that does not want to follow the language of violence and hatred. Two different standpoints are the main poles of discussion. One group wants to use Islamophobia as a concept, the other group opposes the term. In between, there is the scientific concept of Islamophobia that is threatened to be pulverized before it is even fully conceptualized. In the middle position there are also intellectuals known as Islamic reformers who argue that Islamophobia should be replaced by the term Islam-critique.

  1. Diversity: How to Begin the Discussion

    Directory of Open Access Journals (Sweden)

    Brenda Alston-Mills

    2012-12-01

    Full Text Available The perception of diversity and inclusion, as it relates to social justice, often evokes destructive responses, either spoken or unspoken. It is one of the ‘malicious problems’ found in the classroom, the workplace, and amongst other parts of our society. In challenging these problems with diversity and inclusion, conversations regarding the substantive aspects of oppression and inequitable distribution of power of one group over another must be initiated to educate or expand the thinking of our modern day society. Formulating solutions from these conversations, willing individuals must be able to name the issue, analyze its impact, and enact a positive change, while acknowledging the difficulties in creating conversations of an issue that is in dire need of revelation. This report provides a non-controversial presentation, beginning with reasons for resistance, followed by survival strategies, and ending with pro-active strategies to establish dialogue and to allow for personal stories. Further discussion will analyze aggressive behavior, examine critical core values for an individual and organization, discuss positive and effective methods for combating mistreatment, and empowerment strategies to respond positively to oppression. Strategies for engaging an organization are included, such as how to use these tools to co-create a vision for a welcoming environment in organizations, while acknowledging the uncomfortable atmosphere that surrounds the topic of cultural change. Accepting that this uncomfortable environment stems from fear itself, fear is a viable part of the process towards trust and resolution.

  2. Disgust discussed: introduction to the special section.

    Pole, Nnamdi

    2013-03-01

    The author introduces a special section of Psychological Bulletin devoted to the study of disgust. After discussing conflicts between its supposed role as a basic emotion and its more recently understood involvement in responding to moral transgressions, the author summarizes 3 articles contained in the special section. Widen and Russell (2013) present a developmental account of disgust highlighting the ages at which children experience, express, understand, verbalize, and recognize disgust. The article shows that disgust is present early but that recognition of disgust in others is considerably delayed. Chapman and Anderson (2013) review evidence pertaining to the question of whether genuine disgust is elicited by moral transgressions. Their review covers data from self-report, brain imaging, facial behavior, and implicit measures gathered from both experimental and correlational studies. They conclude that moral transgressions elicit genuine disgust. Russell and Giner-Sorolla (2013) ask what types of moral transgressions are most likely to elicit pure disgust. They find that moral transgressions involving body violations are more likely than others to elicit such disgust. Moreover, they suggest that disgust elicited by body violations is likely to be more resistant to modification by context, situation, and efforts at rationalization. Taken together, the reviews support the view that rudiments of disgust to physical objects are present early in life but later become adapted to social influence and new moral purposes. Social implications are discussed. © 2013 American Psychological Association

  3. Just a routine operation: a critical discussion.

    Science.gov (United States)

    McClelland, G; Smith, M B

    2016-05-01

    This article has summarised a critical discussion of the human factors that contributed to the death of a patient from a failure to respond appropriately to a 'can't intubate, can't ventilate' scenario. The contributory factors included the clinical team's inability to communicate, prioritise tasks and demonstrate effective leadership and assertive followership. The film Just a routine operation has now been in circulation for several years. When a system is designed and introduced with the intention of making a change to clinical practice, it can quickly become just another component of an organisation's architecture and complacency around its use can develop. This article has been written specifically for perioperative practitioners to renew the debate around the human factors that contribute to patient harm. By critically discussing Just a routine operation and attempting to review why the incident occurred, this article has attempted to emphasise that some of the conditions and behaviours that contributed to the death of Elaine Bromiley may be latent within our organisations and teams, and may continue to contribute to failures that affect patient safety.

    2008-01-01

    Through analysis of natural and social attributes of earthquake forecasting,the relationship between the natural and social attributes of earthquake forecasting (early warning) has been discussed.Regarding the natural attributes of earthquake forecasting,it only attempts to forecast the magnitude,location and occurrence time of future earthquake based on the aualysis of observational data and relevant theories and taking into consideration the present understanding of seismogeny and earthquake generation.It need not consider the consequences an earthquake forecast involves,and its purpose is to check out the level of scientific understanding of earthquakes.In respect of the social aspect of earthquake forecasting,people also focus on the consequence that the forecasting involves,in addition to its natural aspect,such as the uncertainty of earthquake prediction itself,the impact of earthquake prediction,and the earthquake resistant capability of structures (buildings),lifeline works,etc.In a word,it highlights the risk of earthquake forecasting and tries to mitigate the earthquake hazard as much as possible.In this paper,the authors also discuss the scientific and social challenges faced in earthquake prediction and analyze preliminarily the meanings and content of earthquake early warning.

  5. Brain plasticity, memory, and aging: a discussion

    Energy Technology Data Exchange (ETDEWEB)

    Bennett, E.L.; Rosenzweig, M.R.

    1977-12-01

    It is generally assumed that memory faculties decline with age. A discussion of the relationship of memory and aging and the possibility of retarding the potential decline is hampered by the fact that no satisfactory explanation of memory is available in either molecular or anatomical terms. However, this lack of description of memory does not mean that there is a lack of suggested mechanisms for long-term memory storage. Present theories of memory usually include first, neurophysiological or electrical events, followed by a series of chemical events which ultimately lead to long-lasting anatomical changes in the brain. Evidence is increasing for the biochemical and anatomical plasticity of the nervous system and its importance in the normal functioning of the brain. Modification of this plasticity may be an important factor in senescence. This discussion reports experiments which indicate that protein synthesis and anatomical changes may be involved in long-term memory storage. Environmental influences can produce quantitative differences in brain anatomy and in behavior. In experimental animals, enriched environments lead to more complex anatomical patterns than do colony or impoverished environments. This raises fundamental questions about the adequacy of the isolated animal which is frequently being used as a model for aging research. A more important applied question is the role of social and intellectual stimulation in influencing aging of the human brain.

    Full Text Available Feminism has emerged in a context of struggle for equality.  As formal rights gained ground, material inequalities resulting from ineffective legal rules became evident. These issues are the starting point for the discussion on equality and differences in the field of LGBTI human rights theory. Accordingly, this essay explores the new legal rights gained by the LGBTI community in the Argentine Republic, along with material tensions arising from social reality. Such reality is addressed by relevant literature as well as by the analysis of interviews conducted in the city of Azul, Province of Buenos Aires. The core idea of this essay focuses on the search for a theory connecting both equality and difference when it comes to sexual minorities. 

  11. Discussion of Muskingum method parameter X

    Directory of Open Access Journals (Sweden)

    Xiao-fang RUI

    2008-09-01

    Full Text Available The parameter X of the Muskingum method is a physical parameter that reflects the flood peak attenuation and hydrograph shape flattening of a diffusion wave in motion. In this paper, the historic process that hydrologists have undergone to find a physical explanation of this parameter is briefly discussed. Based on the fact that the Muskingum method is the second-order accuracy difference solution to the diffusion wave equation, its numerical stability condition is analyzed, and a conclusion is drawn: X<=0.5 is the uniform condition satisfying the demands for its physical meaning and numerical stability. It is also pointed out that the methods that regard the sum of squares of differences between the calculated and observed discharges or stages as the objective function and the routing coefficients C0 , C1 and C2 of the Muskingum method as the optimization parameters cannot guarantee the physical meaning of X.

All panelists and the audience were asked to address the following questions • Why is the second law taught in so many different ways? Why so many textbooks on thermodynamics? Why so many schools of thought? • Some say that thermodynamics is limited to equilibrium, others that it extends to nonequilibrium. How is entropy defined for nonequilibrium states?

  13. Panel discussion: Gas emissions with diesel efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Cole, J. [Southwest Research Inst., San Antonio, TX (United States)

    1997-12-31

    The second of three papers in the panel discussion outlined the characteristics of spark-ignited natural gas (SING) engines. Currently, the SING engine is considered less efficient than a diesel engine because of the reduced compression ratio, the use of air-throttles, retarded ignition for low NOx, and increased heat transfer. To improve upon these characteristics and to make the SING engine equal to, or even surpass the diesel engine in efficiency, more research work needs to be done on advanced controls. These include (knock, misfire, humidity detection), various ignition enhancements (variable energy/gap plug, long-life plug, laser ignition), and possibly camless operation (cylinder deactivation, throttleless operation). The late-cycle High Pressure Gas Injection (LaCHIP) as an alternate means of improving the efficiency of natural gas engines was also described.

    2014-07-01

    Full Text Available Open Access (OA, like any other model or strategy for the dissemination of knowledge, carries with it clear benefits as well as costs and downsides. These vary depending on the OA strategy in question, and in order for OA to bring maximum benefit to the world of scholarship, its costs and benefits need be examined carefully and dispassionately so that the former can be maximized and the latter minimized. Unfortunately, the OA advocacy community tends to resist all attempts to examine OA in this way, to the point that those who approach OA in a spirit of critical analysis (rather than celebration and evangelism are attacked and punished. This article describes the problem, provides examples of it, and proposes strategies for promoting a more rigorous and analytical discussion of OA.

    Kohlmann, Wendy; Schiffman, Joshua D

    2016-11-24

    With the introduction of genomic technologies, more hereditary cancer syndromes with hematologic malignancies are being described. Up to 10% of hematologic malignancies in children and adults may be the result of an underlying inherited genetic risk. Managing these patients with hereditary hematologic malignancies, including familial leukemia, remains a clinical challenge because there is little information about these relatively rare disorders. This article covers some of the issues related to the diagnosis and interpretation of variants associated with hereditary hematologic malignancies, including the importance of an accurate family history in interpreting genetic variants associated with disease. The challenges of screening other family members and offering the most appropriate early malignancy detection is also discussed. We now have a good opportunity to better define hereditary cancer syndromes with associated hematologic malignancies and contribute to clinically effective guidelines.

    2008-01-01

    In order to respond the discredit on the design wave standard and to recommend new consideration on design wave parameters, based on the long-term distribution of statistic characteristics of waves and the short-term probability properties of sea state defined by giving the return period, the calculation of the return period, the height, the period, and the oceanic wave parameters of the design wave and the forecasting methods are discussed in this paper. To provide references for the operation reliability of floating structures in the extreme sea state, the method of determining the design wave parameters is resurveyed. A proposal is recommended that the design wave, which can be either significant wave with 500-year of the return period, or the maximum wave with 1/N of exceeding probability, 100-year of the return period, can be applied in the engineering design practice.

  19. Transgenerational epigenetic inheritance: an open discussion.

    Science.gov (United States)

    Nagy, Corina; Turecki, Gustavo

    2015-08-01

    Much controversy surrounds the idea of transgenerational epigenetics. Recent papers argue that epigenetic marks acquired through experience are passed to offspring, but as in much of the field of epigenetics, there is lack of precision in the definitions and perhaps too much eagerness to translate animal research to humans. Here, we review operational definitions of transgenerational inheritance and the processes of epigenetic programing during early development. Subsequently, based on this background, we critically examine some recent findings of studies investigating transgenerational inheritance. Finally, we discuss possible mechanisms that may explain transgenerational inheritance, including transmission of an epigenetic blueprint, which may predispose offspring to specific epigenetic patterning. Taken together, we conclude that presently, the evidence suggesting that acquired epigenetic marks are passed to the subsequent generation remains limited.

  20. A Contribution to Arc Length Discussion

    Directory of Open Access Journals (Sweden)

    Stephan Egerland

    2015-09-01

    Full Text Available Abstract An investigation was raising the question: "What does 'arc length' mean?" Actually, it is considered expressing a kind of natural relationship between arc voltage and arc column shape. Statements such as "The higher the voltage the longer the arc" or "The arc voltage proves approximately proportional to the arc length", are frequently noticed in this conjunction. However, the author suggests that there is no general possibility of describing 'arc length' over the whole welding process range. Instances are represented in this paper, showing both theoretical attempts of definition and practical observations. This paper intends to contribute to a serious discussion of something trivial, indeed very well-known or used among welding experts, but actually yet hardly understood, at least as when it comes to closer examination

    2013-09-01

    Full Text Available Before 9/11 WTC was an international landmark. The definition of the two high-rise buildings identity, their tourist, social, visual and economic significance, disappeared with the destruction of their materiality. As a result, the contemplative visual and unwritten discourse of the Lower Manhattan disappeared together with the architectural, urban, technological essence and also with the philosophy of stability and equilibrium of a prosperous society. At the social-mental level this event triggers a crisis in personal and collective consciences (of the American Nation but also of the Nations, and a crisis of humanity. The architectural - urban and ideas competition organized to select the best urban-social-architectural concept proved to be a difficult task. Not only it had to “fill” a particular place on earth, but it also needed to configure a philosophy of place that would ‘heal” the wounds of the local and international communities, namely the lack of security and prosperity brought on by a no longer hidden technology of aggression bringing cities and communities under threats never experienced before at times of peace. In its first part the article discusses the competition, proposals and the finalized urban project. The particular challenges related to the selection of design in the case of WTC are doubled by a certain complexity related to the institutional arrangements common to most large urban development projects. It is also clear that there is interdependency between the project governance and the project results. These aspects are discussed in the second part of the article.

    2014-03-01

    Full Text Available The task of identifying named entities from the discussion texts in Web forums faces the challenge of noisy names. As the names are often misspelled or abbreviated, the conventional techniques have failed to detect the noisy names properly. In this paper we propose a global context based framework for handling the noisy names. The framework is tested on a named entity recognition system designed to identify the names from the discussion texts in a homeopathy diagnosis discussion forum. The proposed global context-based framework is found to be effective in improving the accuracy of the named entity recognition system.

    Vic Montemayor - No one has been more passionate about improving the quality and effectiveness of the teaching of Medical Physics than Bill Hendee. It was in August of 2008 that the first AAPM Workshop on Becoming a Better Teacher of Medical Physics was held, organized and run by Bill Hendee. This was followed up in July of 2010 with a summer school on the same topic, again organized by Bill. There has been continued interest in alternate approaches to teaching medical physics since those initial gatherings. The momentum established by these workshops is made clear each year in the annual Innovation in Medical Physics Education session, which highlights work being done in all forms of medical physics education, from one-on-one residencies or classroom presentations to large-scale program revisions and on-line resources for international audiences. This symposium, presented on behalf of the Education Council, highlights the work of three finalists from past Innovation in Education sessions. Each will be presenting their approaches to and innovations in teaching medical physics. It is hoped that audience members interested in trying something new in their teaching of medical physics will find some of these ideas and approaches readily applicable to their own classrooms. Rebecca Howell - The presentation will discuss ways to maximize classroom learning, i.e., increasing the amount of material covered while also enhancing students’ understanding of the broader implications of the course topics. Specifically, the presentation will focus on two teaching methodologies, project based learning and flip learning. These teaching methods will be illustrated using an example of graduate medical physics course where both are used in conjunction with traditional lectures. Additionally, the presentation will focus on our experience implementing these methods including challenges that were overcome. Jay Burmeister - My presentation will discuss the incorporation of active

All panelists and the audience were asked to address the following questions • Is the second law relevant when we trap single ions, prepare, manipulate and measure single photons, excite single atoms, induce spin echoes, measure quantum entanglement? Is it possible or impossible to build Maxwell demons that beat the second law by exploiting fluctuations? • Is the maximum entropy generation principle capable of unifying nonequilibrium molecular dynamics, chemical kinetics, nonlocal and nonequilibrium rheology, biological systems, natural structures, and cosmological evolution? • Research in quantum computation and quantum information has raised many fundamental questions about the foundations of quantum theory. Are any of these questions related to the second law?

    This report describes proposed new models for assessment of eight of the nine clinical competencies the American Veterinary Medical Association Council on Education requires for accreditation. The models were developed by discussion groups at the Association of American Veterinary Medical Colleges' Clinical Competency Symposium. Clinical competencies and proposed models (in parentheses) are described. Competency 1: comprehensive patient diagnosis (neurologic examination on a dog, clinical reasoning skills); Competency 2: comprehensive treatment planning (concept mapping, computerized case studies); Competency 3: anesthesia, pain management (student portfolio); Competency 4: surgery skills (objective structured clinical examination, cased-based examination, "super dog" model); Competency 5: medicine skills (clinical reasoning and case management, skills checklist); Competency 6: emergency and intensive care case management (computerized case study or scenario); Competency 7: health promotion, disease prevention/biosecurity (360 degrees evaluation, case-based computer simulation); Competency 8: client communications and ethical conduct (Web-based evaluation forms, client survey, communicating with stakeholders, telephone conversation, written scenario-based cases). The report also describes faculty recognition for participating in clinical competency assessments.

  6. Theoretical NMR correlations based Structure Discussion

    2011-07-01

    Full Text Available Abstract The constitutional assignment of natural products by NMR spectroscopy is usually based on 2D NMR experiments like COSY, HSQC, and HMBC. The actual difficulty of the structure elucidation problem depends more on the type of the investigated molecule than on its size. The moment HMBC data is involved in the process or a large number of heteroatoms is present, a possibility of multiple solutions fitting the same data set exists. A structure elucidation software can be used to find such alternative constitutional assignments and help in the discussion in order to find the correct solution. But this is rarely done. This article describes the use of theoretical NMR correlation data in the structure elucidation process with WEBCOCON, not for the initial constitutional assignments, but to define how well a suggested molecule could have been described by NMR correlation data. The results of this analysis can be used to decide on further steps needed to assure the correctness of the structural assignment. As first step the analysis of the deviation of carbon chemical shifts is performed, comparing chemical shifts predicted for each possible solution with the experimental data. The application of this technique to three well known compounds is shown. Using NMR correlation data alone for the description of the constitutions is not always enough, even when including 13C chemical shift prediction.

  7. Vicarious learning through capturing taskdirected discussions

    1999-12-01

    Full Text Available The research programme on vicarious learning, part of which we report in this paper, has been aimed at exploring the idea that learning can be facilitated by providing learners with access to the experiences of other learners. We use Bandura's term vicarious learning to describe this (Bandura, 1986, and we believe it to be a paradigm that offers particular promise when seen as an innovative way of exploiting recent technical advances in multimedia and distance learning technologies. It offers the prospect of a real alternative to the building of intelligent tutors (which directly address the problem of allowing learners access to dialogue, but which have proved largely intractable in practice or to the direct support of live dialogues (which do not offer a solution to the problem of providing 'live' tutors - unless they are between peer learners. In the research reported here our main objectives were to develop techniques to facilitate learners' access to, especially, dialogues and discussions which have arisen when other learners were faced with similar issues or problems in understanding the material. This required us to investigate means of indexing and retrieving appropriate dialogues and build on these to create an advanced prototype system for use in educational settings.

    This article reports an open discussion that took place during the Keenan Symposium "Meeting the Entropy Challenge" (held in Cambridge, Massachusetts, on October 4, 2007) following the short presentations—each reported as a separate article in the present volume—by Seth Lloyd, Owen Maroney, Silviu Guiasu, Ping Ao, Jochen Gemmer, Bernard Guy, Gian Paolo Beretta, Speranta Gheorghiu-Svirschevski, and Dorion Sagan. All panelists and the audience were asked to address the following questions • Why is the second law true? Is it an inviolable law of nature? If not, is it possible to develop a perpetual motion machine of the second kind? • Are second law limitations objective or subjective, real or apparent, due to the nature of physical states or the representation and manipulation of information? Is entropy a physical property in the same sense as energy is universally understood to be an intrinsic property of matter? • Does the second law conflict with quantum mechanics? Are the differences between mechanical and thermodynamic descriptions of physical phenomena reconcilable? Does the reversible law of motion of hamiltonian mechanics and quantum mechanics conflict with the empirical observation of irreversible phenomena?

  9. Discussion of material rotation and stress rate

    Energy Technology Data Exchange (ETDEWEB)

    Dienes, J.K.

    1985-10-01

    Characterization of material behavior can be divided into two parts, the analysis of deformation and the underlying physics, though these are intimately related. A significant advance in the analysis of deformation was made when the polar decomposition theorem was introduced, making it possible to separate large deformations into a stretch and a rotation. Consequences of the theorem affect the way rate processes should be characterized. In particular, rate of material rotation is different from vorticity, and the stress rate for finite strains is different from the usual stress rate of Zaremba, Jaumann, and Noll. It is convenient to define a strain rate that is different from the stretching that is the symmetric part of the velocity gradient. These concepts are described in detail in a 1979 paper. Various criticisms of that paper have appeared in the Journal of Applied Mechanics, which are discussed herein. To illustrate the distinction, it is shown that the rate of rotation in a classical vortex does not vanish, though the vorticity is zero. It is also shown that the rate of material rotation recently computed by Nemat-Nasser, which involves an eigenvalue expansion, is equivalent to the one given in the 1979 paper, which makes use of matrix inversion, and it asseverated that the matrix inversion approach is computationally more efficient. 17 refs.

  10. Indigenous healing practice: ayahuasca. Opening a discussion.

    Science.gov (United States)

    Prue, Robert; Voss, Richard W

    2014-01-01

    This essay frames an invitation to pastoral counselors and pastoral theologians to examine connections and perhaps interactions between themselves and traditional shamanic healers who use ayahuasca in their healing ceremonies. Indigenous people in South America have used ayahuasca for centuries, and the ritual has become common among the mestizo populations in urban areas of the Amazon, particularly as a curing ritual for drug addiction (Dobkin de Rios, 1970; Moir, 1998). Like peyote in the United States (Calabrese, 1997) ayahuasca use amongst the indigenous people of the Amazon is a form of cultural psychiatry. A review of the literature reveals very little commentary or discussion of shamanic practice in Pastoral Counseling (Pastoral Theology). The scant literature identifies an antithetical relationship at best. The current authors wonder about the possibility of to including shamanic practices in the context of pastoral counseling? This essay seeks to provide some basic information about the ritual use of ayahuasca and to offer a rationale for pastoral counselors to engage in a dialogue about its utility.

  11. The future of MEBC: panel discussion.

    Science.gov (United States)

    Biczó, G

    1995-01-01

    The expected developments in the not too distant future (5-10 years) of molecular electronics and biocomputing (MEBC) are discussed. In the short-term, the study of very specific basic phenomena is expected (e.g. conducting polymers, strange electronic states of insulating polymers, bacteriorhodopsin (BR), arrays of molecules, self-organization of biomaterials, very specific biological systems, quantum coherence in cytoskeletal microtubules, optoelectronic information storage, associative memories, pattern recognition, hierarchical nature of biological information). New application fields outside the range of conventional technology (e.g. randomized algorithms, optoelectronic devices, chemical and biosensors, as well as a certain extent of commercialisation) have also been predicted. In the long-term, the study and solution of much deeper (sometimes scientific fiction-like) problems were foreseen, such as the self-organization of biomaterials, artificial self-reproduction, implementation of artificial cell dynamic control structures based on molecular devices for medical and environmental applications and the construction of neuronal computers as aids to the human brain.

  12. Bioethics and multiculturalism: nuancing the discussion.

    Science.gov (United States)

    Durante, Chris

    2017-08-11

    In his recent analysis of multiculturalism, Tom Beauchamp has argued that those who implement multicultural reasoning in their arguments against common morality theories, such as his own, have failed to understand that multiculturalism is neither a form of moral pluralism nor ethical relativism but is rather a universalistic moral theory in its own right. Beauchamp's position is indeed on the right track in that multiculturalists do not consider themselves ethical relativists. Yet, Beauchamp tends to miss the mark when he argues that multiculturalism is in effect a school of thought that endorses a form of moral universalism that is akin to his own vision of a common morality. As a supporter of multiculturalism, I would like to discuss some aspects of Beauchamp's comments on multiculturalism and clarify what a multicultural account of public bioethics might look like. Ultimately, multiculturalism is purported as a means of managing diversity in the public arena and should not be thought of as endorsing either a version of moral relativism or a universal morality. By simultaneously refraining from the promotion of a comprehensive common moral system while it attempts to avoid a collapse into relativism, multiculturalism can serve as the ethico-political framework in which diverse moralities can be managed and in which opportunities for ethical dialogue, debate and deliberation on the prospects of common bioethical norms are made possible. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  13. Water, food, and population -- a panel discussion.

    Science.gov (United States)

    1996-01-01

    This paper summarizes a conference panel discussion among parliamentarians and researchers on water and food supplies and population growth in Asia. The Western Samoa legislator urged delegates to be aware of human development that was no more than the promotion of values associated with a market economy. Samoans increased their per capita caloric consumption. The food supply is provided locally, and 90% of exports are food products. Food security would be jeopardized by a fivefold increase in population. Samoan human development indicators were relatively good for a developing country. However, the country was still ranked as a low-income, food-deficit country. The Pakistani delegate explained that Pakistan's agriculture used the largest, continuous irrigation system in the world. However, the system operated inefficiently. There was concern that future high population growth would jeopardize food security. Another barrier was institutional mismanagement of irrigation and reliance on imports for staple items. Agricultural productivity must increase to meet the increased needs of continued population growth. All available land is currently under cultivation. Future strategies will necessitate international cooperation and innovative and environmentally sound technology. Professor Xuan remarked that increased population growth and rising demand, decreased water quality, and changing consumption patterns were a threat to water supplies. Sustainable increases in food production would entail better water management: reforestation to reduce and prevent water runoff, better technological exploitation of rain water, and more efficient use of irrigation systems. Better international financing schemes were needed for support of these policy changes. Professor Ness suggested free markets in water in order to price water at actual rates of consumption. Polluters should pay. Water management was also threatened by global warming.

    Comparison of outcomes for cancer patients discussed and not discussed at a multidisciplinary meeting (MDM). Retrospective analysis of the association of MDM discussion with survival. All newly diagnosed cancer patients from 2009 to 2012, presenting to a large regional cancer service in South West Victoria, Australia (620 colorectal, 657 breast, 593 lung and 511 haematological) were recorded and followed up to 5 years after diagnosis. Treatment patterns and survival of patients whose treatment was discussed at an MDM compared to those who were not, were explored. The proportion of patients presented to an MDM within 60 days after diagnosis was 56% (n = 366) for breast cancer, 59% (n = 363) for colorectal cancer, 27% (n = 137) for haematological malignancies and 60% (n = 355) for lung cancer. Seventy-three percent (n = 886) of patients discussed at an MDM had their tumour stage recorded in their medical records while only 52% (n = 604) of patients not discussed had their tumour stage recorded (P HR] 0.62, 95% confidence interval [CI] 0.50-0.76, P HR 0.58, 95% CI 0.35-0.96, P = 0.03) compared to patients whose cases were not discussed at an MDM after adjusting for the potential cofounders of age, stage, comorbidities and treatment. This was not the case for colorectal and breast cancer patients where there was no significant difference. MDM discussion has been recommended as best practice in the management of cancer patients, however, from a public health perspective this creates potential issues around access and resources. It is likely that MDM presentation patterns and outcomes across tumour streams are linked in complex ways. We believe that our data would demonstrate that these patterns differ across tumour streams and that more detailed work is required to better allocate relatively scarce and potentially costly MDM resources to tumour streams and patient groups that may get the most benefit.

    Full Text Available Video is being used widely in professional development. Yet, little is known about how to design video-based learning environments that are productive for teacher learning. One promising model is a video club (Sherin, 2000. Video clubs bring teachers together to view and analyze video segments from one another’s classrooms. The idea is that by watching and discussing video segments focused on student thinking, teachers will learn practices for identifying and analyzing noteworthy student thinking during instruction and can use what they learn to inform their instructional decisions. This paper addresses issues to consider when setting up a video club for teacher education, such as defining goals for using video, establishing norms for viewing and discussing one another’s teaching, selecting clips for analysis, and facilitating teacher discussions. Si consiglia la discussione tra osservatori. Nei Video Club gli insegnanti mettono a fuoco le modalità con cui gli studenti apprendono.Il video è stato ampiamente utilizzato per la formazione professionale.

Questo articolo affronta le questioni da considerare quando si configura un video club per la formazione degli insegnanti, come ad esempio la definizione di obiettivi per l'utilizzo dei video, le norme per la visione e discussione dei rispettivi video, la selezione

    Wikipedia articles are by definition never finished. Many of them have associated talk pages, where their content is discussed by editors. Here we analyse the evolution of these discussions to unveil temporal patterns in the interactions in such a large production community. First, we investigate peaks in the discussion activity and their relation with peaks in edits to articles; furthermore we introduce a measure to account for how fast discussions grow in complexity. The results point out the high impact of time instant specific hot topics on the amount and speed of the discussions, suggesting them as a mirror of a collective stream of consciousness.

  16. Simulating social dilemmas: promoting cooperative behavior through imagined group discussion.

    Science.gov (United States)

    Meleady, Rose; Hopthrow, Tim; Crisp, Richard J

    2013-05-01

    A robust finding in social dilemmas research is that individual group members are more likely to act cooperatively if they are given the chance to discuss the dilemma with one another. The authors investigated whether imagining a group discussion may represent an effective means of increasing cooperative behavior in the absence of the opportunity for direct negotiation among decision makers. Five experiments, utilizing a range of task variants, tested this hypothesis. Participants engaged in a guided simulation of the progressive steps required to reach a cooperative consensus within a group discussion of a social dilemma. Results support the conclusion that imagined group discussion enables conscious processes that parallel those underlying the direct group discussion and is a strategy that can effectively elicit cooperative behavior. The applied potential of imagined group discussion techniques to encourage more socially responsible behavior is discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved

    Wang, Yongheng; Cao, Kening; Zhang, Xiaoming

    2013-03-01

    With the rapid development of online communities, mining and extracting quality knowledge from online discussions becomes very important for the industrial and marketing sector, as well as for e-commerce applications and government. Most of the existing techniques model a discussion as a social network of users represented by a user-based graph without considering the content of the discussion. In this paper we propose a new multilayered mode to analysis online discussions. The user-based and message-based representation is combined in this model. A novel frequent concept sets based clustering method is used to cluster the original online discussion network into topic space. Domain ontology is used to improve the clustering accuracy. Parallel methods are also used to make the algorithms scalable to very large data sets. Our experimental study shows that the model and algorithms are effective when analyzing large scale online discussion data.

  19. The group discussion effect: integrative processes and suggestions for implementation.

    Science.gov (United States)

    Meleady, Rose; Hopthrow, Tim; Crisp, Richard J

    2013-02-01

    One of the most consistent findings in experimental social dilemmas research is the positive effect group discussion has on cooperative behavior. At a time when cooperation and consensus is critical to tackle global problems, ranging from debt to deforestation, understanding the dynamics of group discussion is a pressing need. Unfortunately, research investigating the underlying processes and implementation of the effect has been inconclusive. The authors present a critical review of existing explanations and integrate these perspectives into a single process model of group discussion, providing a more complete theoretical picture of how interrelated factors combine to facilitate discussion-induced cooperation. On the basis of this theoretical analysis, they consider complimentary approaches to the indirect and feasible implementation of group discussion. They argue that such strategies may overcome the barriers to direct discussion observed across a range of groups and organizations.

    2015-05-01

    The World Health Organization has called for a dramatic increase in the number of midwives and supports the use of innovative programs to assist students in achieving midwifery competencies. Online discussion boards are excellent educational tools for stimulating in-depth student engagement. However, complex discussions can be difficult to grade without a well-constructed rubric. The 'discussion-board APGAR' provides clear scoring criteria for discussions of midwifery care. The discussion-board APGAR has 5 components: Application, Professionalism, Group work, Analysis, and Rationale and provides scoring criteria for unacceptable, marginal, and proficient performance. The discussion-board APGAR is based on the Core Competencies for Basic Midwifery Practice in the United States (US), consistent with the International Confederation of Midwives Essential Competencies for Basic Midwifery Practice, and can be adjusted to be congruent with other midwifery standards.

    Leinonen, Risto; Asikainen, Mervi A.; Hirvonen, Pekka E.

    2017-06-01

    This study analyzes the types of peer discussion that occur during lecture-based tutorial sessions. It focuses in particular on whether discussions of this kind have certain characteristics that might indicate success in the post-testing phase. The data were collected during an introductory physics course. The main data set was gathered with the aid of audio recordings. Data-driven content analysis was applied in the analysis to facilitate the placement of students' discussions in particular categories related to different types of discussions. Four major discussion types were found: discussions related to the content knowledge, metalevel discussions including metaconceptual and metacognitive elements, discussions related to practical issues, and creating a base for discussion, seen here in the order of their prevalence. These categories were found to possess individual substructures that involved, for example, asking and answering questions, participating in a dialogue, or disagreeing with a peer. Analyzing the substructures of the categories revealed that there were evident differences between the groups, some of them related to the group size. With regard to the characteristics of discussions considered to be connected to a better learning outcome, it was observed that a great number of lines uttered related to the physics content or metalevel discussions seemed to have a direct bearing on success in the post test at the group level. For individual students, answering content-related questions posed by their peers might also indicate success in the post test. We would encourage researchers to continue this type of research in order to discover the essential characteristics of students' discussions that facilitate learning.

    Marsden, Rachael; Botell, Rachel

    Sexual relationships remain an important aspect of life for people living with motor neurone disease. This article explores the use of the Extended-PLISSIT model when discussing relationships and sexual function with patients and their partners in a motor neurone disease clinic. The model provides a structured approach to assist discussions with patients as well as promoting reflection and exchange of knowledge in the multidisciplinary team. It is a useful model when addressing issues that are sometimes difficult to discuss.

  5. Learning through online discussion: a framework evidenced in learners' interactions

    Directory of Open Access Journals (Sweden)

    2011-02-01

    Full Text Available Online learning, often supported through online discussion, is not only a popular means of supporting off-campus learners, but increasingly has a place within campus-based learning courses. Laurillard and others suggest that there are assumptions being made about learning through online discussion that have yet to be fully tested, and therefore there is a need to examine this area further. Tutors and learners may benefit from having a greater insight and understanding of how engaging in asynchronous online discussion presents opportunities for learning on an individual and a collective basis. This research study focused on learners' engagement with online discussion and their perceptions of how engaging in online discussion impacts on learning. This paper revisits learning through online discussion and proposes a framework, which emerges from the analysis of learners' experiences. A grounded theory approach was used in the collection and analysis of six learner case studies within a higher education setting, exploring learners' interactions in online discussion, and their perceptions of learning through online discussion. Insights into the learners' interactions were provided by the learners themselves through semi-structured interviews. The grounded approach to the analysis of the interviews enabled the learners' voices to be heard in terms of what they thought about learning through online discussion. The insight enabled through the depth of description from the learners and the examination of the online interactions led to the development of a framework for learning through online discussion. The framework raises the importance of articulation as a key process in learning whilst highlighting the opportunities for collaborative informed thinking by engaging with the ideas of others. The focus given to the learning process through the framework will be of interest to tutors and learners who use online asynchronous discussion environments for

  16. The power of talk: developing discriminatory group norms through discussion.

    Science.gov (United States)

    Smith, Laura G E; Postmes, Tom

    2011-06-01

    Research has shown that group discussion can increase intergroup prejudice and discrimination. However, we know little about the process by which discussion has this effect. Therefore, four studies were conducted in a real-world context to investigate this process. Results suggest that discussing a negative societal stereotype (relative to individual rumination in Studies 1 and 3 and alternative discussions in Studies 2 and 3) increases intentions to engage in discrimination against the out-group target of the stereotype. This is mediated by the formation of an in-group norm which supports discrimination (Study 1) and the extent to which the discussion validates the stereotype (Study 2). A fourth study manipulated the extent to which consensus on the negative stereotype was reached through discussion. When the discussion ended in consensus, participants have greater intention to undertake collective action against the stereotyped out-group, mediated by a congruent in-group norm. These results provide evidence that the process by which discussion increases intergroup discrimination is via the formation of discriminatory local group norms. ©2010 The British Psychological Society.

    Focus group discussion is a research methodology in which a small group of participants gather to discuss a specified topic or an issue to generate data. The main characteristic of a focus group is the interaction between the moderator and the group, as well as the interaction between group members. The objective is to give the researcher an understanding of the participants' perspective on the topic in discussion. Focus groups are rapidly gaining popularity in health and medical research. This paper presents a general introduction of the use of focus groups as a research tool within the context of health research, with the intention of promoting its use among researchers in healthcare. A detailed methodology for the conduct of focus groups and analysis of focus group data are discussed. The potentials and limitations of this qualitative research technique are also highlighted.

  6. International Discussion Meeting on High-Tc Superconductors

    CERN Document Server

    1988-01-01

    In the past two years conferences on superconductivity have been characterized by the attendance of hundreds of scientists. Consequently, the organizers were forced to schedule numerous parallel sessions and poster presentations with an almost unsurveyable amount of information. It was, therefore, felt that a more informal get-together, providing ample time for a thourough discussion of some topics of current interest in high-temperature superconductivity, was timely and benefitial for leading scientists as well as for newcomers in the field. The present volume contains the majority of papers presented at the International Discussion Meeting on High-Tc Superconductors held at the Mauterndorf Castle in the Austrian Alps from February 7 to 11, 1988. Each subject was introduced in review form by a few invited speakers and then discussed together with the contributed poster presentations.

    2016-09-01

    Being in the moment, showing compassion, being non-judgmental, acknowledging deep emotional challenges without getting stuck: these are mindfulness characteristics important to us as teachers, yet not often included in teacher preparation. These concerns become magnified when we focus on difficult knowledge and thorny issues, like topics related to gender and race. Using a sociocultural framework, we address how mindfulness, heuristics, and other contemplative practices can be adopted to create safe, supporting, and healing spaces for such complex, often emotionally painful discussions. Participant narratives are used extensively to provide a voice to those marginalized or hurt. Drawing from these narratives and their experience in discussing thorny issues, we put forth possible solutions and interventions that can create spaces that encourage and support critical discourse through mindful practices. The development of a heuristic for discussing thorny issues whose characteristics can be adopted by interested teachers and educators to help frame and mediate this type of difficult discussion is an outcome of this research.

    The field of health literacy has closely examined the readability of written health materials to optimize patient comprehension. Few studies have examined spoken communication in a way that is comparable to analyses of written communication. The study objective was to characterize the structural elements of residents' spoken words while obtaining informed consent. Twenty-six resident physicians participated in a simulated informed consent discussion with a standardized patient. Audio recordings of the discussions were transcribed and analyzed to assess grammar statistics for evaluating language complexity (e.g., reading grade level). Transcripts and time values were used to assess structural characteristics of the dialogue (e.g., interactivity). Discussions were characterized by physician verbal dominance. The discussions were interactive but showed significant differences between the physician and patient speech patterns for all language complexity metrics. In this study, physicians spoke significantly more and used more complex language than the patients.

    Tests and final examination scores of three semesters of control students in a nursing foundation course were compared with tests and final examination scores of three semesters of participating students. Participating students were offered access to an asynchronous pretest online discussion activity with a faculty e-moderator. While the simplified Bloom's revised taxonomy assisted in creating appropriate preparatory test and final examination questions for pretest online discussion, Salmon's five-stage online method provided direction to the e-moderator on how to encourage students to achieve Bloom's higher-order thinking skills during the pretest online discussions. Statistical analysis showed the pretest online discussion activity had a generally positive impact on tests and final examination scores, when controlling for a number of possible confounding variables, including instructor, cumulative grade point average, age, and credit hours.

Participation, defined as including both physical interaction with exhibits, and dialogic interaction between visitors, facilitated the sharing of ideas and feelings between visitors. Exhibits with elements of curiosity and challenge were found to attract...... pupils’ attention but also worked well with other design principles to engage the pupils in sustained reflection and discussion. While other contextual factors remain significant in determining visitor responses, this paper argues that the use of design principles can help create visitor experiences...

    In this article we discuss a model used to introduce the concept of entropy with secondary school students. It can be used to discuss with students the reversibility of time, the tendency towards homogeneity and the link between probability theory and second law of thermodynamics. The model is useful to introduce crucial epistemological issues and helps student to understand the deep connection between the macroscopic and the microscopic.

    Full Text Available This paper examines how the discussion tool is used to promote critical thinking in an online environment at Marshall University. The significance of critical thinking in higher education has been brought to attention at both national and local levels. The paper studies the use of discussions as an approach to promote critical thinking in a number of English as a Second Language (ESL courses offered by Marshall University's Graduate School of Education and Professional Development (GSEPD program. At the end of the semester, a qualitative survey was developed to identify the effectiveness of such discussions, and the opportunities for improvement. The survey was sent to all students in these three classes. These students were all full time teachers in Elementary and Secondary schools in West Virginia. Out of 21 students, 15 of them have responded to the three questions asked in the survey. Almost all the respondents have found discussion helpful in enhancing learning and critical thinking. Most students support the involvement of an online instructor in the online discussion, and faculty members involved in these discussions function as helpers in the development of critical thinking skills.

  10. Scaffolding scientific discussion using socially relevant representations in networked multimedia

    1999-11-01

    How do students make use of social cues when learning on the computer? This work examines how students in a middle-school science course learned through on-line peer discussion. Cognitive accounts of collaboration stress interacting with ideas, while socially situated accounts stress the interpersonal context. The design of electronic environments allows investigation into the interrelation of cognitive and social dimensions. I use on-line peer discussion to investigate how socially relevant representations in interfaces can aid learning. First, I identify some of the variables that affect individual participation in on-line discussion, including interface features. Individual participation is predicted by student attitudes towards learning from peers. Second, I describe the range of group outcomes for these on-line discussions. There is a large effect of discussion group on learning outcomes which is not reducible to group composition or gross measures of group process. Third, I characterize how students (individually) construct understanding from these group discussions. Learning in the on-line discussions is shown to be a result of sustained interaction over time, not merely encountering or expressing ideas. Experimental manipulations in the types of social cues available to students suggest that many students do use socially relevant representations to support their understanding of multiple viewpoints and science reasoning. Personalizing scientific disputes can afford reflection on the nature of scientific discovery and advance. While there are many individual differences in how social representations are used by students in learning, overall learning benefits for certain social representations can be shown. This work has profound implications for design of collaborative instructional methods, equitable access to science learning, design of instructional technology, and understanding of learning and cognition in social settings.

  11. Doctors discussing religion and spirituality: A systematic literature review.

    Best, Megan; Butow, Phyllis; Olver, Ian

    2016-04-01

    Discussion of religion and/or spirituality in the medical consultation is desired by patients and known to be beneficial. However, it is infrequent. We aimed to identify why this is so. We set out to answer the following research questions: Do doctors report that they ask their patients about religion and/or spirituality and how do they do it? According to doctors, how often do patients raise the issue of religion and/or spirituality in consultation and how do doctors respond when they do? What are the known facilitators and barriers to doctors asking their patients about religion and/or spirituality? A mixed qualitative/quantitative review was conducted to identify studies exploring the physician's perspective on discussion of religion and/or spirituality in the medical consultation. We searched nine databases from inception to January 2015 for original research papers reporting doctors' views on discussion of religion and/or spirituality in medical consultations. Papers were assessed for quality using QualSyst and results were reported using a measurement tool to assess systematic review guidelines. Overall, 61 eligible papers were identified, comprising over 20,044 physician reports. Religion and spirituality are discussed infrequently by physicians although frequency increases with terminal illness. Many physicians prefer chaplain referral to discussing religion and/or spirituality with patients themselves. Such discussions are facilitated by prior training and increased physician religiosity and spirituality. Insufficient time and training were the most frequently reported barriers. This review found that physician enquiry into the religion and/or spirituality of patients is inconsistent in frequency and nature and that in order to meet patient needs, barriers to discussion need to be overcome. © The Author(s) 2015.

    Full Text Available Abstract Background The completeness of preferences is assumed as one of the axioms of expected utility theory but has been subject to little empirical study. Methods Fifteen non-health professionals was recruited and familiarised with the standard gamble technique. The group then met five times over six months and preferences were elicited independently on 41 scenarios. After individual valuation, the group discussed the scenarios, following which preferences could be changed. Changes made were described and summary measures (mean and median before and after discussion compared using paired t test and Wilcoxon Signed Rank Test. Semi-structured telephone interviews were carried out to explore attitudes to discussing preferences. These were transcribed, read by two investigators and emergent themes described. Results Sixteen changes (3.6% were made to preferences by seven (47% of the fifteen members. The difference between individual preference values before and after discussion ranged from -0.025 to 0.45. The average effect on the group mean was 0.0053. No differences before and after discussion were statistically significant. The group valued discussion highly and suggested it brought four main benefits: reassurance; improved procedural performance; increased group cohesion; satisfying curiosity. Conclusion The hypothesis that preferences are incomplete cannot be rejected for a proportion of respondents. However, brief discussion did not result in substantial number of changes to preferences and these did not have significant impact on summary values for the group, suggesting that incompleteness, if present, may not have an important effect on cost-utility analyses.

    2009-01-01

    Full Text Available The article discusses the semiology of aphasias, which started being developed in the 19th century by Broca and Wernicke. We do not provide an exhaustive list of symptoms and syndromes to address the theme, since we aim to critically discuss why the semiology of aphasias is still based mainly on organic perspectives in clinical practice and scientific research. We also discuss the contributions of Luria and Jakobson to a better understanding of how language is affected in aphasias and how Modern Linguistics, in special the Discursive Neurolinguistics, may enlighten the debate. We analyze some data to illustrate the theoretical and methodological assumptions of the above mentioned approaches and also discuss the excessive strength that classifications have in the clinical context.

  14. Frequency of Faith and Spirituality Discussion in Health Care.

    Bergamo, David; White, Dawn

    2016-04-01

    Faith and spirituality are important in the lives of many individuals, and therefore, many patients. This study was performed to determine whether faith and spirituality are active part of the healthcare field and patients' receipt of these sometimes delicate topics. The nuances of the concepts of faith, spirituality, and religion and their implications in the healthcare setting are discussed. Benefits and detriments of faith and spirituality are reviewed in terms of how they relate to the health of the patient and to the healthcare field. With the focus of healthcare shifting to holistic care, this conversation may be more necessary than ever in practice, yet it seems many providers are not discussing these matters with patients. The study analyzes whether healthcare providers are discussing these topics with patients and how the discussion is received or would be received by patients. Findings demonstrate the infrequency of the discussion regardless of the fact that the majority of patients consider themselves faithful or spiritual. This study was approved by the Clarkson University Institutional Review Board on June 18, 2104.

  15. Discovering High-Quality Threaded Discussions in Online Forums

    2014-01-01

    Archives of threaded discussions generated by users in online forums and discussion boards contain valuable knowledge on various topics. However, not all threads are useful because of deliberate abuses, such as trolling and flaming, that are commonly observed in online conversations. The existence of various users with different levels of expertise also makes it difficult to assume that every discussion thread stored online contains high-quality contents. Although finding high-quality threads automatically can help both users and search engines sift through a huge amount of thread archives and make use of these potentially useful resources effectively, no previous work to our knowledge has performed a study on such task. In this paper, we propose an automatic method for distinguishing high-quality threads from low-quality ones in online discussion sites. We first suggest four different artificial measures for inducing overall quality of a thread based on ratings of its posts. We then propose two tasks involving prediction of thread quality without using post rating information. We adopt a popular machine learning framework to solve the two prediction tasks. Experimental results on a real world forum archive demonstrate that our method can significantly improve the prediction performance across all four measures of thread quality on both tasks. We also compare how different types of features derived from various aspects of threads contribute to the overall performance and investigate key features that play a crucial role in discovering high-quality threads in online discussion sites.

At first, bring up some data from the thematic seminar "Being a man today: discussing some scratches masculinity," presented at the International Seminar Reviews Routes III, held in Porto Alegre, Brazil, in 2011. Therefore, we discuss the process of male socialization and scores some aspects of everyday life that can endanger / or scratch threaten masculinity, such as seeking care and even the aging process itself. It is noted that the heteronormative masculinity configures itself as the hegemonic model, stand out among other models. So, being a man is to fulfill roles and prescriptions which are rooted in a society that is structured on the basis of gender, even for this have to endanger your health.

    Full Text Available The first translations of Freud's work into Portuguese have presented problems because they were not translated from the German language. More than a hundred years after the beginning of Psychoanalysis, there are still many discussions on Freud's metapsychology and a considerable difficulty in obtaining a consensus on the translation of some concepts. This paper refers back to Freud's concepts of primal repression, repression and suppression. In order to discuss such concepts, we have made use of a film, co-produced by Germans and Argentineans, which is named "The Song in me" (Das Lied in mir, released to the public in 2011 and directed by Florian Micoud Cossen. Through this motion picture, the following of Freud's concepts are analyzed, and the differentiation between them is discussed: suppression and repression, as well as the importance of their precise translation.

  18. Synthetic biology analysed tools for discussion and evaluation

    CERN Document Server

    2016-01-01

    Synthetic biology is a dynamic, young, ambitious, attractive, and heterogeneous scientific discipline. It is constantly developing and changing, which makes societal evaluation of this emerging new science a challenging task, prone to misunderstandings. Synthetic biology is difficult to capture, and confusion arises not only regarding which part of synthetic biology the discussion is about, but also with respect to the underlying concepts in use. This book offers a useful toolbox to approach this complex and fragmented field. It provides a biological access to the discussion using a 'layer' model that describes the connectivity of synthetic or semisynthetic organisms and cells to the realm of natural organisms derived by evolution. Instead of directly reviewing the field as a whole, firstly our book addresses the characteristic features of synthetic biology that are relevant to the societal discussion. Some of these features apply only to parts of synthetic biology, whereas others are relevant to synthetic bi...

    Pilot study to examine if the addition of a structured framework improved the quality of clinical reasoning demonstrated within clinically based online discussions by occupational therapy students undertaking fieldwork. Cognitive elements of the clinical reasoning process present within students' discussions were compared before (2005 cohort) and after (2007 cohort) the introduction of a structured framework to guide discussions. Students' self reports (2007 cohort) of clinical reasoning skills were also analysed before and after two consecutive fieldwork placements. The structured framework increased the proportion of postings containing the advanced 'evaluate' element of clinical reasoning and decreased the proportion of postings containing only the basic 'understand' elements. Self-reported clinical reasoning skills improved following the first fieldwork placement and this improvement was sustained following the second placement. The structured framework appears useful in enhancing students' depth of clinical reasoning during fieldwork, although further investigation is required. © 2010 The Authors.

    2015-07-15

    The public discussion on nuclear energy is not focused on power plant safety anymore. A globally good safety statistic and years of information activity on safety technology provided progress, even though all incidents are still discussed with great dedication. Nevertheless the field of disposal receives more prominence in public discussions since 1976; reprocessing of irradiated fuels and storage of nuclear waste follow the topic of nuclear power plants with temporary shift. During a long preparation time technical and operational know-how was gathered for both fields that is now available for use on large technical scale. For the entire disposal complex exists a comprehensive concept prepared by the federal government, which has to be put into practice together with the industry. The priority assignment for a dialogue with the public is to comprehensively inform on extend and quality of problem solutions and to highlight that even here the safety of the biological-cycle is the guiding principle for all considerations.

    It has been suggested that increased hepatic and intramuscular fat is associated with insulin resistance, and that increased pancreatic fat is related to impaired insulin secretion. We postulated that in obese nondiabetic teenagers insulin levels would be directly related to increases in intramuscular and hepatic fat and inversely related to increases in pancreatic fat. MRI was used to assess the percentage of fat in the liver, muscle and pancreas in 15 healthy Mexican-American girls, 14-17 years old, with body mass indexes (BMIs) ranging from 17.7 kg/m{sup 2} to 46 kg/m{sup 2}. Strong correlations were observed between BMI and fat content in the liver, muscle, and pancreas (r{sup 2}s between 0.50 and 0.89; P<0.003). Serum insulin levels were closely associated with fat measures in the muscle and liver (r{sup 2s}P=0.001 and P=0.023, respectively). In contrast to our hypothesis, fat content in the pancreas was also directly related to insulin secretion (r{sup 2}=0.74; P=0.001). Summary: We conclude that in nondiabetic teenagers, obesity is associated with an increased accumulation of fat in the pancreas without impairment of insulin secretion. (orig.)

    We review the theoretical approaches for investigations of the high energy hadron-hadron scattering in the Regge kinematics. It is demonstrated, that the gluon in QCD is reggeized and the Pomeron is a composite state of the reggeized gluons. Remarkable properties of the BFKL equation for the Pomeron wave function in QCD and supersymmetric gauge theories are outlined. Due to the AdS/CFT correspondence the BFKL Pomeron is equivalent to the reggeized graviton in the extended N=4 SUSY. The properties of the maximal transcendentality and integrability are realized in this model. The BDS multi-gluon scattering amplitudes are investigated in the Regge limit. They do not contain the Mandelstam cuts and are not valid beyond one loop. It is shown, that the hamiltonian for these composite states coincides with the hamiltonian of an integrable open Heisenberg spin chain. (orig.)

    CERN Document Server

    Deriglazov, Alexei A

    2015-01-01

    MPTD-equations in the Lagrangian formulation correspond to the minimal interaction of spin with gravity. Due to the interaction, in the Lagrangian equations instead of the original metric $g$ emerges spin-dependent effective metric $G=g+h(S)$. So we need to decide, which of them the MPTD-particle sees as the space-time metric. We show that MPTD-equations, if considered with respect to original metric, have no physically admissible solutions: acceleration of the particle grows up to infinity as its speed approximates to the speed of light. If considered with respect to $G$, the theory is consistent. But the metric now depends on spin, so there is no unique space-time manifold for the Universe of spinning particles: each particle probes his own three-dimensional geometry. This can be improved by adding a non-minimal interaction, and gives the modified MPTD-equations with reasonable behavior within the original metric.

    2010-01-01

    While same-sex marriage debates have captured public attention, it is but one component of a broader discussion regarding the role of marriage in a changing society. To inform this discussion, I draw on qualitative, Internet survey data from 102 self-identified asexual individuals. I find that asexual relationships are complicated and nuanced in ways that have implications for a GLBTQ political agenda, including same-sex marriage recognition. In addition, findings indicate that assumptions of sex and sexuality in relationships are problematic and that present language for describing relationships is limiting. Findings suggest a social justice agenda for marginalized sexualities should be broader in scope than same-sex marriage.

    Full Text Available Architecture develops along with particular society changing. In the period of modern, some traditional architecture with their complex rules become considered old fashioned. It was not implemented in modern buildings. When functionality becomes priority, minimalist architecture, recognized as Neo-Modernism, spreads and offers reflection of modern lifestyle. However, every style is not always suitable for each circumstance. The unconditional application of style can create another problem instead of a solution. This essay will discuss the existence of minimalism in architecture; its historical relationship with modernism, the theoretical reviews which underpin the discussion and the appropriate adaptations need to be made to fit in tropical climate.
