    In February 2010, Secretary of Defense Robert Gates and Chairman of the Joint Chiefs of Staff Adm. Michael Mullen established the Comprehensive Review Working Group (CRWG) to conduct a comprehensive review of the issues associated with a repeal of Don't Ask, Don't Tell (DADT). Over the next 10 months, the CRWG undertook one of the most extensive studies of a personnel issue in the history of the U.S. military. This article describes the work and the findings of the CRWG (on which the author served) in the context of the activities within the Department of Defense (DoD) following President Obama's call for DADT repeal in his January 2010 State of the Union Address and leading up to the passage of the Don't Ask, Don't Tell Repeal Act in December 2010. It argues that the CRWG served a number of important functions in the DADT repeal process, particularly that it a) provided a rigorous, fact-based assessment of the impacts of repeal from which DoD senior leaders and Congress could base their views; b) developed a road map for a smooth and orderly implementation of repeal; and c) opened a conversation among military service members about what repeal would really mean to them. In doing so, the CRWG contributed to what has been a largely incident-free and successful transition to a post-DADT military.

  3. Oilsands for the USA : while environmental groups ask for a shutdown, new study shows significant resulting economic benefits in America

    The United States is beginning to appreciate the value of having massive oil sands resources located in relatively close proximity to their northern border. This article discussed a recent study conducted by the Canadian Energy Research Institute (CERI) to assess the impact of Canada's oil sands development on the economy of the United States. The study forecasted that the demand for oil sands-related goods and services from American companies will continue to increase as the industry expands. The top national-level goods and services impacts will be derived from increases in manufacturing; finance; insurance; real estate; and professional, scientific, and technical services. Accommodation and food services in the United States will also benefit from the growth of the oil sands industry. The United States may not risk pushing ahead with strict carbon-cutting legislation targeting the oil sands when policy-makers consider the potential impacts of Canada selling its resources to China. 1 fig.

  4. [Significance of expert-guided groups for relatives in psychiatry].

    Psychiatric interest in relatives of patients was concentrated in the past on their pathogenetic and etiological influence on mental illness. The medical paradigma of mental illness did not account for relatives affliction in psychic disturbance of their family member. Against this a community care oriented approach involves relatives into psychiatric care, particularly under the aspects of coping strategies and rehabilitative sources. Practicability and effects of this approach were explored in expert-guided relative groups at the Psychiatric Hospital Gütersloh (FRG). Results indicated that relatives are concerned with a series of problems. Participating in relative groups facilitates coping with these problems. Expert-guided and relative centered groups were found helpful, discharging and encouraging for relatives.

  6. An emergency department intervention to protect an overlooked group of children at risk of significant harm.

    2012-02-01

    BACKGROUND: Parental psychiatric disorder, especially depression, personality disorder and deliberate self-harm, is known to put children at greater risk of mental illness, neglect or physical, emotional and sexual abuse. Without a reliable procedure to identify children of parents presenting with these mental health problems, children at high risk of significant harm can be easily overlooked. Although deliberate self-harm constitutes a significant proportion of emergency presentations, there are no guidelines which address the emergency physician\\'s role in identifying and assessing risk to children of these patients. METHODS: A robust system was jointly developed with the local social services child protection team to identify and risk-stratify children of parents with mental illness. This allows us to intervene when we identify children at immediate risk of harm and to ensure that social services are aware of potential risk to all children in this group. The referral process was audited repeatedly to refine the agreed protocol. RESULTS: The proportion of patients asked by the emergency department personnel about dependent children increased and the quality of information received by the social services child protection team improved. CONCLUSIONS: All emergency departments should acknowledge the inadequacy of information available to them regarding patients\\' children and consider a policy of referral to social services for all children of parents with mental health presentations. This process can only be developed through close liaison within the multidisciplinary child protection team.

    Tissue cholestasis is a histologic feature in some patients with alcoholic liver disease, but its significance is unknown. We studied prospectively the clinical, laboratory, and histologic findings of 306 chronic male alcoholics in whom liver tissue was available. Tissue cholestasis permitted identification of two groups: group I, absent or mild cholestasis (239 patients), and group II, moderate to severe cholestasis (67 patients). Statistical evaluation was performed by Student's t test and regression analyses. In patients with tissue cholestasis, 97% had elevated serum cholylglycine levels, while only 61% had significant jaundice (serum bilirubin greater than 5 mg/dl). In patients without tissue cholestasis, 66% had elevated serum cholylglycine and 13.5% jaundice. Highly significant statistical correlations (P less than 0.0001) were found between cholestasis and malnutrition, prothrombin time, AST, alkaline phosphatase, bilirubin, Maddrey's discriminant function, serum cholylglycine level, albumin, and histologic severity score. In group I, 54% survived 60 months versus 22% in group II (P less than 0.0001). Highly significant statistical correlations (P less than 0.0001) were noted between serum cholylglycine levels and the parameters enumerated earlier, but not with survival. We conclude that tissue cholestasis is a highly significant prognostic indicator of outcome in alcoholic hepatitis and is more consistently associated with bile salt retention than jaundice.

  13. Presence and potential significance of aromatic-ketone groups in aquatic humic substances

    1987-01-01

    Aquatic humic- and fulvic-acid standards of the International Humic Substances Society were characterized, with emphasis on carbonyl-group nature and content, by carbon-13 nuclear-magnetic-resonance spectroscopy, proton nuclear-magnetic-resonance spectroscopy, and infrared spectroscopy. After comparing spectral results of underivatized humic and fulvic acids with spectral results of chemically modified derivatives, that allow improved observation of the carbonyl group, the data clearly indicated that aromatic ketone groups comprised the majority of the carbonyl-group content. About one ketone group per monocyclic aromatic ring was determined for both humic and fulvic acids. Aromatic-ketone groups were hypothesized to form by photolytic rearrangements and oxidation of phenolic ester and hydrocarbon precursors; these groups have potential significance regarding haloform formation in water, reactivity resulting from active hydrogen of the methyl and methylene adjacent to the ketone groups, and formation of hemiketal and lactol structures. Aromatic-ketone groups also may be the point of attachment between aliphatic and aromatic moieties of aquatic humic-substance structure. ?? 1987.

    Full Text Available This paper investigates the significance of combining cepstral features derived from the modified group delay function and from the short-time spectral magnitude like the MFCC. The conventional group delay function fails to capture the resonant structure and the dynamic range of the speech spectrum primarily due to pitch periodicity effects. The group delay function is modified to suppress these spikes and to restore the dynamic range of the speech spectrum. Cepstral features are derived from the modified group delay function, which are called the modified group delay feature (MODGDF. The complementarity and robustness of the MODGDF when compared to the MFCC are also analyzed using spectral reconstruction techniques. Combination of several spectral magnitude-based features and the MODGDF using feature fusion and likelihood combination is described. These features are then used for three speech processing tasks, namely, syllable, speaker, and language recognition. Results indicate that combining MODGDF with MFCC at the feature level gives significant improvements for speech recognition tasks in noise. Combining the MODGDF and the spectral magnitude-based features gives a significant increase in recognition performance of 11% at best, while combining any two features derived from the spectral magnitude does not give any significant improvement.

    What makes a successful team? In this issue our contributors look closely at the subject and come up with several answers. Working on team chemistry is the "Activation Energy" Dr. Owen Gadeken's story is about. Scott Cameron thinks it's getting to know people one to one. Tony Maturo says it's getting the most out of your support staff. Dr. Michael Hecht finds the best people he can and build the team around their talents. Teamwork is a theme we explore often in Academy Sharing Knowledge (ASK), but never so directly as in this issue. You'll not only find formulas for building successful teams, you'll see examples of ones in action, strategies for how project managers can motivate their teams, and expert advice on how to choose who to work with and who not to work with. It seems like all the stories make one common point: everyone on a team counts. Few project managers can pull off a project alone, and when the whole team is performing to everyone's potential, the chances of pulling off a successful project goes up exponentially. If that doesn't seem like enough by itself, listen to this... Discerning fans of ASK will note the last two issues our Special Feature was "There are no Mistakes, Only Lessons." We have not abandoned this feature, but for now we want to broaden our repertoire. In this issue we add a new Special Feature, "My Metaphor," starting with Paul Espinosa's article "My Big Wall" about his rock climbing adventures on El Capitan in Yosemite National Park. If you think getting to Mars is work, read what it's like to scale a 3,000-foot rock face. This issue we're also welcoming two new members to our Review Board, Hugh Woodward and Jody Kusek. Hugh and Jody are our first reviewers from outside NASA, and we are delighted to have them on our team.

    2014-06-01

    At least a third of women across reproductive ages experience low sexual desire and impaired arousal. There is increasing evidence that mindfulness, defined as non-judgmental present moment awareness, may improve women's sexual functioning. The goal of this study was to test the effectiveness of mindfulness-based therapy, either immediately or after a 3-month waiting period, in women seeking treatment for low sexual desire and arousal. Women participated in four 90-min group sessions that included mindfulness meditation, cognitive therapy, and education. A total of 117 women were assigned to either the immediate treatment (n = 68, mean age 40.8 yrs) or delayed treatment (n = 49, mean age 42.2 yrs) group, in which women had two pre-treatment baseline assessments followed by treatment. A total of 95 women completed assessments through to the 6-month follow-up period. Compared to the delayed treatment control group, treatment significantly improved sexual desire, sexual arousal, lubrication, sexual satisfaction, and overall sexual functioning. Sex-related distress significantly decreased in both conditions, regardless of treatment, as did orgasmic difficulties and depressive symptoms. Increases in mindfulness and a reduction in depressive symptoms predicted improvements in sexual desire. Mindfulness-based group therapy significantly improved sexual desire and other indices of sexual response, and should be considered in the treatment of women's sexual dysfunction.

    THIS ISSUE FEATURES A VISUAL DEPICTION OF THE ACADEMY of Program and Project Leadership (APPL). I imagine a variety of initial reactions to the drawing. One might be, "What is a cartoon doing in a magazine about project management?" Or perhaps, "Wow, nice colors-and fun." Another may be to closely search the image for signs, symbols and meaning. Still another, to read a new level of innovation and creativity into the picture. Undoubtedly, some readers will raise questions about the cost. Of course, any reaction is a sign of engagement. The stronger, the more energized the emotional and cognitive processing, the better. It is a sign of attention and interaction. For I've heard it said, "You only need to worry if they don t care one way or the other." So what is the point of the picture? To stimulate interest, raise questions, promote discussion, and maybe raise a smile.. .That, at least, was my initial reaction when I was introduced to the work of Nancy Hegedus, who helps to create these drawings for Root Learning Inc. At the NASA PM Conference, I was first shown the work Nancy had been doing with the help of Goddard s Knowledge Management Architect, Dr. Ed Rogers. I was immediately drawn into the power of visualization as a tool for more effective learning, communicating, and conveying complex knowledge concepts. We need new tools in today s world, where information and data overwhelms by sheer volume. There are articles, pamphlets, communications, and white papers-all aiming to convince and influence. Reactions to these tend to be either avoidance or mind-numbing, heavy-eyed consent; the message never registers or enters the soul. That s one of the reasons that APPL s Knowledge Sharing Initiative (KSI) has turned to storytelling as a memorable way of transfer- ring knowledge, inspiring imitation of best practices, and spurring reflection. ASK Magazine s recent fourth birthday marks an important milestone in APPL s continuing quest to provide ongoing support to

  20. On the Question of Methodological Support of Research on Relationships of Interpersonal Significance in Kindergarten Groups

    Full Text Available The paper focuses on the importance of in-depth research (in particular, employing an algorithm developed by M.Yu. Kondratyev for defining integral status of an individual on child-child interpersonal relationship in kindergarten groups. Although relationships with significant adults are by all means essential for preschool children, interpersonal relation- ships on the child-child level to a great extent shape the content of the social situation of development in general. Still, when it comes to revealing status and role position of the child in the structure of interpersonal relationships within the kindergarten group, there’s the challenge of defining informal intragroup structure of power in contact community (due to the age specifics. The paper suggests how this challenge may be addressed and provides a version of the technique suitable for preschoolers that helps overcome age restrictions implied by the original technique. Also, the paper reports on the outcomes of approbation of this version which proved its heuristic nature. For instance, the outcomes show a high degree of correlation between the results of kindergarten group members ranking in accordance with their influence upon peers carried out by teachers working in these groups.

  1. Corrective interpersonal experience in psychodrama group therapy: a comprehensive process analysis of significant therapeutic events.

    2011-07-01

    This study investigated the process of resolving painful emotional experience during psychodrama group therapy, by examining significant therapeutic events within seven psychodrama enactments. A comprehensive process analysis of four resolved and three not-resolved cases identified five meta-processes which were linked to in-session resolution. One was a readiness to engage in the therapeutic process, which was influenced by client characteristics and the client's experience of the group; and four were therapeutic events: (1) re-experiencing with insight; (2) activating resourcefulness; (3) social atom repair with emotional release; and (4) integration. A corrective interpersonal experience (social atom repair) healed the sense of fragmentation and interpersonal disconnection associated with unresolved emotional pain, and emotional release was therapeutically helpful when located within the enactment of this new role relationship. Protagonists who experienced resolution reported important improvements in interpersonal functioning and sense of self which they attributed to this experience.

    Middle Ordovician age Chickamauga Group carbonates crop out along the Birmingham and Murphrees Valley anticlines in central Alabama. The macrofossil contents on exposed surfaces of seven bioherms have been counted to determine their various paleontologic characteristics. Twelve groups of organisms are present in these bioherms. Dominant organisms include bryozoans, algae, brachiopods, sponges, pelmatozoans, stromatoporoids and corals. Minor accessory fauna include predators, scavengers and grazers such as gastropods, ostracods, trilobites, cephalopods and pelecypods. Vertical and horizontal niche zonation has been detected for some of the bioherm dwelling fauna. No one bioherm of those studied exhibits all 12 groups of organisms; rather, individual bioherms display various subsets of the total diversity. Statistical treatment (G-test) of the diversity data indicates a lack of statistical homogeneity of the bioherms, both within and between localities. Between-locality population heterogeneity can be ascribed to differences in biologic responses to such gross environmental factors as water depth and clarity, and energy levels. At any one locality, gross aspects of the paleoenvironments are assumed to have been more uniform. Significant differences among bioherms at any one locality may have resulted from patchy distribution of species populations, differential preservation and other factors.

  3. Deriving statistical significance maps for SVM based image classification and group comparisons.

    Population based pattern analysis and classification for quantifying structural and functional differences between diverse groups has been shown to be a powerful tool for the study of a number of diseases, and is quite commonly used especially in neuroimaging. The alternative to these pattern analysis methods, namely mass univariate methods such as voxel based analysis and all related methods, cannot detect multivariate patterns associated with group differences, and are not particularly suitable for developing individual-based diagnostic and prognostic biomarkers. A commonly used pattern analysis tool is the support vector machine (SVM). Unlike univariate statistical frameworks for morphometry, analytical tools for statistical inference are unavailable for the SVM. In this paper, we show that null distributions ordinarily obtained by permutation tests using SVMs can be analytically approximated from the data. The analytical computation takes a small fraction of the time it takes to do an actual permutation test, thereby rendering it possible to quickly create statistical significance maps derived from SVMs. Such maps are critical for understanding imaging patterns of group differences and interpreting which anatomical regions are important in determining the classifier's decision.

    OBJECTIVE: Given international variation in obstetric practices and outcomes, comparison of labour outcomes in different ethnic groups could provide important information regarding the underlying reasons for rising caesarean delivery rates. Increasing numbers of women from Eastern European countries are now delivering in Irish maternity hospitals. We compared labour outcomes between Irish and Eastern European (EE) women in a large tertiary referral center. STUDY DESIGN: This was a prospective consecutive cohort study encompassing a single calendar year. The cohort comprised 5550 Irish and 867 EE women delivered in a single institution in 2009. Women who had multiple pregnancies, breech presentation, and elective or pre-labour caesarean sections (CS) were excluded. Data obtained from birth registers included maternal age, nationality, parity, gestation, onset of labour, mode of delivery and birth weight. RESULTS: The overall intrapartum CS rate was 11.4% and was significantly higher in Irish compared to EE women (11.8% vs. 8.8%; p=0.008). The proportion of primiparas was lower in Irish compared to EE women (44.8% vs. 63.6%; p<0.0001). The intrapartum CS rate was almost doubled in Irish compared to EE primiparas (20.7% vs. 11.0%; p<0.0001). Analysis of primiparas according to labour onset revealed a higher intrapartum CS rate in Irish primiparas in both spontaneous (13.5% vs. 7.2%; p<0.0001) and induced labour (29.5% vs. 19.3%; p=0.005). Irish women were older with 19.7% of primiparas aged more than 35, compared to 1.6% of EE women (p<0.0001). The primigravid CS rate in Irish women was significantly higher in women aged 35 years or older compared women aged less than 35 (30.6% vs. 18.3%; p<0.0001) consistent in both spontaneous and induced labour. The primiparous induction rate was 45.4% in Irish women compared to 32% in EE women, and more Irish women were induced before 41 weeks gestation. CONCLUSION: The results highlight that primigravid intrapartum CS rates were

    Background Kell null (K0) individuals can produce anti-Ku, an antibody against many epitopes in the Kell glycoprotein, after transfusion and/or pregnancy. Since sensitized K0 patients are rare, little is known about anti-Ku clinical relevance and in particular about its association to hemolytic disease of the fetus and newborn. Case Report This work describes a case of neonatal hyperbilirubinemia due to immune-mediated erythrocyte destruction by an alloantibody directed against the Kell glycoprotein. Serologic and molecular approaches identified an anti-Ku alloantibody in maternal serum. A homozygous IVS3 + 1g>a point mutation (KEL*02N.06 allele) was found to be responsible for the lack of Kell antigen expression in the mother's red blood cell and subsequent alloimmunization after a previous pregnancy. Even though in most cases Kell antibodies are clinically severe and may cause suppression of erythropoiesis, in our case the newborn had a moderate anemia and hyperbilirubinemia that was successfully treated with phototherapy without requiring exchange transfusion. Serological and molecular studies performed in the proband's family members allowed us to provide them with proper counseling regarding alloimmunization after transfusion and/or pregnancy. Conclusions This case enlarges the understanding of the clinical significance of alloantibodies against Kell blood group antigens.

    Objective Hyperchromatic crowded groups (HCG), a term first introduced into the cytology literature by DeMay in 1995, are commonly observed in Pap tests and may rarely be associated with serious but difficult to interpret lesions. In this study, we specifically defined HCG as dark crowded cell groups with more than 15 cells which can be identified at 10× screening magnification. Methods We evaluated consecutive liquid-based (Surepath) Pap tests from 601 women (age 17–74 years, mean age 29.4 yrs) and observed HCG in 477 cases. In all 477 HCG cases, Pap tests were found to be satisfactory and to contain an endocervical sample. HCG were easily detectible at 10× screening magnification (size up to 400 um, mean 239.5 um) and ranged from 1 to 50 (mean 19.5) per Pap slide. Results HCG predominantly represented 3-Dimensional groups of endocervical cells with some nuclear overlap (379/477 – 79%), reactive endocervical cells with relatively prominent nucleoli and some nuclear crowding (29/477 – 6%), clusters of inflammatory cells (25/477 – 5.2%), parabasal cells (22/477 – 4.6%), endometrial cells (1/477 – 0.2%). Epithelial cell abnormalities (ECA) were present in only 21 of 477 cases (4.6%). 18 of 21 women with HCG-associated ECA were less than 40 years old; only 3 were =/> 40 years. HCG-associated final abnormal Pap test interpretations were as follows: ASCUS (6/21 – 28%), LSIL (12/21 – 57%), ASC-H (2/21 – 9.5%), and HSIL/CIN2-3 (3/21 – 14%). The association of HCG with ECA was statistically significant (p = 0.0174. chi-square test). In patients with ECA, biopsy results were available in 10 cases, and 4 cases of biopsy-proven CIN2/3 were detected. Among these four cases, HCG in the Pap tests, in retrospect represented the lesional high grade cells in three cases (one HSIL case and two ASC-H cases). Interestingly, none of the 124 cases without HCG were found to have an epithelial cell abnormality. Conclusion We conclude: a. HCG are observed in a high

  11. Frustration, anger, and the significance of alter-ego transferences in group psychotherapy.

    Science.gov (United States)

    Stone, W N

    1995-07-01

    When working with narcissistically vulnerable and angry patients in group psychotherapy one must take into account the entire treatment context. Interaction takes place among the identified patient, the other members, the therapist, and the image of the group as a whole. In members' counter-reactions to the difficult person, group-destructive forces frequently are stimulated. The offending individual may flee, or the group may reach an impasse in which little growth occurs. In this communication, I have focused on alter-ego relationships and transferences as a way of understanding aspects of group formation and destruction. Angry patients may have intense wishes to be like others and to feel part of the human condition. They suffer from feeling alone. Disruption of an alter-ego relationship may result in rage. A self-psychological perspective in concert with knowledge of group dynamics enables the clinician to formulate ways of intervening in problematic group interactions. The therapist's capacity to attend to the vulnerabilities of the self of all persons involved in the group is often severely tested, particularly under circumstances of emotional contagion. Elucidation of twinship and alter-ego transferences may help stabilize difficult patients and enable them to restart their psychological growth.

  13. GOAL: A software tool for assessing biological significance of genes groups

    Directory of Open Access Journals (Sweden)

    Famili Fazel

    2010-05-01

    Full Text Available Abstract Background Modern high throughput experimental techniques such as DNA microarrays often result in large lists of genes. Computational biology tools such as clustering are then used to group together genes based on their similarity in expression profiles. Genes in each group are probably functionally related. The functional relevance among the genes in each group is usually characterized by utilizing available biological knowledge in public databases such as Gene Ontology (GO, KEGG pathways, association between a transcription factor (TF and its target genes, and/or gene networks. Results We developed GOAL: Gene Ontology AnaLyzer, a software tool specifically designed for the functional evaluation of gene groups. GOAL implements and supports efficient and statistically rigorous functional interpretations of gene groups through its integration with available GO, TF-gene association data, and association with KEGG pathways. In order to facilitate more specific functional characterization of a gene group, we implement three GO-tree search strategies rather than one as in most existing GO analysis tools. Furthermore, GOAL offers flexibility in deployment. It can be used as a standalone tool, a plug-in to other computational biology tools, or a web server application. Conclusion We developed a functional evaluation software tool, GOAL, to perform functional characterization of a gene group. GOAL offers three GO-tree search strategies and combines its strength in function integration, portability and visualization, and its flexibility in deployment. Furthermore, GOAL can be used to evaluate and compare gene groups as the output from computational biology tools such as clustering algorithms.

    A prospective multicenter study. To evaluate the use of magnetic resonance imaging, in the differentiation between monoclonal gammopathies of unknown significance and multiple myeloma. Although multiple myeloma has been studied extensively with magnetic resonance imaging, to the authors' knowledge, no study has evaluated the clinical interest of magnetic resonance imaging in the differentiation between monoclonal gammopathies of unknown significance and multiple myeloma. The magnetic resonance examinations of the thoracolumbar spine in 24 patients with newly diagnosed monoclonal gammopathies of unknown significance were compared with those performed in 44 patients with newly diagnosed nontreated multiple myeloma. All findings on magnetic resonance examination performed in patients with monoclonal gammopathies of unknown significance were normal, whereas findings on 38 (86%) of the 44 magnetic resonance examinations performed in patients with multiple myeloma were abnormal. Magnetic resonance imaging can be considered as an additional diagnostic tool in differentiating between monoclonal gammopathies of unknown significance and multiple myeloma, which may be helpful when routine criteria are not sufficient. An abnormal finding on magnetic resonance examination in a patient with monoclonal gammopathies of unknown significance should suggest the diagnosis of multiple myeloma after other causes of marrow signal abnormalities are excluded. Magnetic resonance imaging also may be proposed in the long-term follow-up of monoclonal gammopathies of unknown significance when a new biologic or clinical event suggests the diagnosis of malignant monoclonal gammopathy.

  16. Water Desalination through Zeolitic Imidazolate Framework Membranes: Significant Role of Functional Groups.

    Gupta, Krishna M; Zhang, Kang; Jiang, Jianwen

    2015-12-08

    A molecular simulation study is reported for water desalination through five zeolitic imidazolate framework (ZIF) membranes, namely ZIF-25, -71, -93, -96, and -97. The five ZIFs possess identical rho-topology but differ in functional groups. The rejection of salt (NaCl) is found to be around 97% in ZIF-25, and 100% in the other four ZIFs. The permeance ranges from 27 to 710 kg/(m(2)·h·bar), about one∼two orders of magnitude higher compared with commercial reverse osmosis membranes. Due to a larger aperture size da, ZIF-25, -71, and -96 exhibit a much higher water flux than ZIF-93 and -97; however, the flux in ZIF-25, -71, and -96 is governed by the polarity of functional group rather than da. With the hydrophobic CH3 group, ZIF-25 has the highest flux despite the smallest da among ZIF-25, -71, and -96. The lifetime of hydrogen bonding in ZIF-25 is shorter than that in ZIF-71 and -96. Furthermore, water molecules undergo a fast flushing motion in ZIF-25, but frequent jumping in ZIF-96 and particularly in ZIF-97. An Arrhenius-type relationship is found between water flux in ZIF-25 and temperature, and the activation energy is predicted to be 6.5 kJ/mol. This simulation study provides a microscopic insight into water desalination in a series of ZIFs, reveals the key factors (aperture size and polarity of functional group) governing water flux, and suggests that ZIF-25 might be an interesting reverse osmosis membrane for high-performance water desalination.

    A discrepancy exists between the 7th edition guidelines of the American Joint Committee on Cancer (AJCC) and the 3rd edition Japanese treatment guidelines in terms of the classification of No. 12a lymph nodes as regional or distant lymph nodes in D2 lymphadenectomy for gastric cancer. The scope definition of No. 12a lymph nodes has yet to be fully elucidated. The present study aimed to assess the appropriateness of reclassifying No. 12a lymph node metastasis as distant metastasis according to the survival rate outcome, and to provide a clear and practical definition of the No. 12a group lymph nodes of gastric cancer. A retrospective analysis was performed on patients with gastric cancer who underwent standard or greater lymphadenectomy between January 2000 and December 2009 to find an association between No. 12a node metastasis and survival outcome. The present study first presented a clear and practical scope definition of the No. 12a group lymph nodes of gastric cancer, according to our clinical experiences and practices (Table I and Fig. 1). The survival outcome of patients with gastric cancer and No. 12a lymph node metastasis was poorer compared with that of patients with no No. 12a lymph node metastasis (P=0.0003). The results were similar in stage III patients with gastric cancer (Pcancer (P=0.1968). Cox regression analysis revealed that the AJCC stage was independently associated with an unfavorable cumulative survival rate. Logistic regression analysis revealed that tumor location, AJCC stage, intravascular cancer emboli and nerve invasion were associated with No. 12a lymph node metastasis. In conclusion, the data in the present study suggested that No. 12a lymph node metastasis is associated with distant metastasis, and therefore they concur with the 7th edition AJCC gastric cancer guidelines, which appear to be correct in terms of considering No. 12a lymph node metastasis as distant metastasis.

    2006-02-01

    Mesoproterozoic (∼1600 Ma old) Salkhan Limestone (Semri Group)of the Vindhyan Supergroup, exposed in Rohtas district of Bihar,India,preserves an abundant and varied ancient microbial assemblage.These microfossils are recorded in three distinctly occurring cherts viz.,bedded chert, stromatolitic chert and cherty stromatolites.27 morphoforms belonging to 14 genera and 21 species have been recognized.Six unnamed forms are also described. The microbial assemblage,almost exclusively composed of the remnants of cyanobacteria,is dominated by entophysalidacean members and short trichomes and can be termed as ‘typical Meso-proterozoic microbiotas ’.The assemblage includes characteristic mat-forming scytonematacean and entophysalidacean cyanobacteria. Eoentophysalis is the dominant organism in the assemblage. Ellipsoidal akinetes of nostocalean cyanobacteria (Archaeollipsoides) and spherical unicells also occur;both are distinct from mat forming assemblage,allochthonous and possibly planktic.Co-occurrence of the microbiotas and precipitates is related to the depositional environment of the Mesoproterozoic tidal flats with high carbonate saturation.

    Significant differences in the incidence levels of lung cancer have been observed among major Chinese dialect groups or communities (Kokkien, Teochew and Cantonese) in Singapore. Among males, the incidence rate is highest in the Hokkiens (age-standardized incidence rate per 100,000 persons per year in Hokkien 67.8, Teochew 55.3, Cantonese 54.0) and among females, it is highest in the Cantonese (Hokkien 12.4, Teochew 12.8, Cantonese 27.2). The present investigation was undertaken to determine the incidence rates of each of the main histological types of lung cancer in the Chinese population and to determine whether there are any correlations between histological patterns and the dialect group differentials that may be of aetiological significance. During the period 1968-1972, a total of 1,747 cases of lung cancer (1,285 males and 462 females) were reported to the Singapore Cancer Registry. It proved possible to type the neoplasms histologically in 476 males (37.0%) and 154 females (33.3%). Age-standardized rates by histological type were computed on the assumption that those histologically typed were a representative sample of all lung cancers. This study shows that Hokkien males have a significantly higher incidence rate of epidermoid carcinoma than the other dialect groups (Hokkien 36.1, Teochew 21.1, Cantonese 17.3). The Cantonese females have significantly higher incidence rates of both epidermoid carcinoma (Hokkien 3.7, Teochew 2.3, Cantonese 5.9) and adenocarcinoma (Hokkien 4.6, Teochew 3.6, Cantonese 11.9). Various sources of bias in studied of this type were examined; it is concluded that the differences in the histologic-specific incidence rates of lung cancer among the various Chinese dialect groups in Singapore are real and not artefactual. The significance of these findings in relation to possible aetiological factors is discussed.

  6. Changes of High Mobility Group box 1 in Serum of Pig Acute Hepatic Failure Model and Significance

    2008-01-01

    The role of the high mobility group box 1 (HMGB-1) in acute hepatic failure and the ef- fect of artificial liver support system treatment on HMGB-1 level were investigated. Pig models of acute hepatic failure were induced by D-galactosamine and randomly divided into two groups with or without artificial liver support system treatment. Tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) levels were detected by the enzyme linked immunosorbent assay (ELISA), the expression of HMGB-1 by Western blot, and serum levels of HMGB-1, liver function and hepatic pathology were observed after artificial liver support system treatment. The levels of TNF-α and IL-1β were increased and reached the peak at 24th h in the acute hepatic failure group, then quickly decreased. The serum level of HMGB-1 was increased at 24th h in the acute hepatic failure group and reached the peak at 48th h, then kept a stable high level. Significant liver injury appeared at 24th h and was continuously getting worse in the pig models of acute hepatic failure. In contrast, the liver injury was significantly alleviated and serum level of HMGB-1 was significantly decreased in the group treated with artificial liver support system (P<0.05). It was suggested that HMGB-1 may participate in the inflammatory response and liver injury in the late stage of the acute liver failure. Artificial liver support system treatment can reduce serum HMGB-1 level and relieve liver pathological damage.

  8. Are Healthcare Providers Asking about Environmental Exposures? A Community-Based Mixed Methods Study

    Directory of Open Access Journals (Sweden)

    Kristina M. Zierold

    2015-01-01

    Full Text Available People living near environmental hazards may develop symptoms and health conditions that require specialized monitoring and treatment by healthcare providers. One emerging environmental hazard is coal ash. Coal ash is comprised of small particles containing heavy metals, polycyclic aromatic hydrocarbons, and radioactive elements. The overall purpose of this study was to explore whether healthcare providers ask patients if they live near an environmental hazard like coal ash storage sites and to assess what health conditions prompt a provider inquiry. Focus groups were conducted in 2012 and a cross-sectional survey was administered in 2013. Overall, 61% of survey respondents reported that their healthcare providers never asked if they lived near an environmental hazard. One focus group member stated “No, they don’t ask that. They just always blame stuff on you….” Respondents with asthma and other lung conditions were significantly more likely to be asked by a healthcare provider if they lived near an environmental hazard. Due to the unique exposures from environmental hazards and the low prevalence of patients being asked about environmental hazards, we recommend that healthcare providers take environmental health histories in order to understand patients’ exposures, to monitor symptoms of exposure, and to assist with education about reducing exposure.

  16. The efficacy of adult christian support groups in coping with the death of a significant loved one.

    Science.gov (United States)

    Goodman, Herbert; Stone, Mark H

    2009-09-01

    Psychologists sometimes minimize important resources such as religion and spiritual beliefs for coping with bereavement. Alienation of therapeutic psychology from religious values contrasts to professional and public interest in religious experience and commitment. A supportive viewpoint has come about partially as a result of recognizing important values which clinicians have found absent in many of their clients. Until spiritual belief systems become integrated into the work of clinicians, clients may not be fully integrative in coping with loss. The key finding of this study was that individuals who participated in Christian and secular support groups showed no statistically significant difference in their mean endorsement of negative criteria on the BHS, and no statistically significant difference for their mean score endorsement of positive criteria on the RCOPE. However, a Christian-oriented approach was no less effective than a psychological-oriented one. In both groups, a spiritual connection to a specific or generalized higher power was frequently identified which clients ascribed to facilitating the management of their coping.

  17. Provenance and U-Pb geochronology of the Upper Cretaceous El Chanate Group, northwest Sonora, Mexico, and its tectonic significance

    Science.gov (United States)

    Jacques-Ayala, C.; Barth, A.P.; Wooden, J.L.; Jacobson, C.E.

    2009-01-01

    The Upper Cretaceous El Chanate Group, northwest Sonora, Mexico, is a 2.8km thick clastic sedimentary sequence deposited in a continental basin closely related to volcanic activity. It consists of three formations: the Pozo Duro (oldest), the Anita, and the Escalante (youngest). Petrographic study, conglomerate pebble counts, and U-Pb geochronology of detrital zircons were performed to determine the source and age of this sequence, and to interpret its tectonic setting. In the sandstones of all three formations, the most abundant grains are those of volcanic composition (Q38F22L 40, Q35F19L46, and Q 31F22L47, respectively). The Pozo Duro Formation includes well-rounded quartz-arenite clast conglomerates, whereas conglomerates of the two upper units have clasts predominantly of andesitic and rhyolitic composition. The most likely source for these sediments was the Jurassic volcanic arc exposed in northern Sonora and southern Arizona. Zircons from five sandstone samples define two main age groups, Proterozoic and Mesozoic. The first ranges mostly from 1000 to 1800Ma, which suggests the influence of a cratonic source. This zircon suite is interpreted to be recycled and derived from the same source area as the quartz-rich sandstone clasts in the basal part of the section. Mesozoic zircons range from Triassic to Late Cretaceous, which confirms the proposed Late Cretaceous age for the sequence, and also corroborates Jurassic felsic source rocks. Another possible source was the Alisitos volcanic arc, exposed along the western margin of the Baja California Peninsula. Of regional significance is the great similarity between the El Chanate Group and the McCoy Mountains Formation of southeastern California and southwestern Arizona. Both are Cretaceous, were deposited in continental environments, and have similar zircon-age patterns. Also, both exhibit intense deformation and locally display penetrative foliation. These features strongly suggest that both units underwent

  5. Significance of grooming behavior in two polygynous groups of western black crested gibbons: Implications for understanding social relationships among immigrant and resident group members.

    2013-12-01

    In primates, grooming is considered among the most common behaviors for maintaining social bonds; however, to date, few studies have examined grooming behavior in gibbon species in detail. We used both a 5-min interval scan method and social network analysis to study grooming in two groups of polygynous western black-crested gibbon (Nomascus concolor) in Wuliang Mountain, Central Yunnan, China. Individuals in both groups spent little time in social grooming (1.45% and 1.97% of active time). We compared the two groups' grooming networks and found that the group that maintained a more stable social unit had a more complex grooming network while the group with new immigrants had a grooming network characterized by fewer grooming pairs. Females in both groups played important roles in the grooming network. A newly immigrant female spent the most time grooming others and chose the resident adult female as her main adult grooming partner. Other females from both groups chose the adult male as their primary grooming partner (except their offspring). A sub-adult male who had resided in his natal group for 2 years after maturing into an adult also groomed more and was at the center of the network. This male finally replaced the breeding male in his group 3 years after our data collection period ended. We hypothesize that the immigrant female and the resident young adult male engaged in more extensive grooming interactions as a behavioral strategy to gain tolerance from long-term residents. Our results suggest that female gibbons in polygynous groups actively cooperate in maintaining social relationships rather than co-exist through tolerance or avoidance. Our observations indicate that grooming networks in crested gibbons reflect individual dynamics and partly support the social cohesion hypothesis for primate grooming. In this regard, we suggest that changes in gibbon grooming networks can be used to predict social change.

    Children can influence the foods available at home, but some ways of approaching a parent may be better than others; and the best way may vary by type of parent. This study explored how parents with different parenting styles would best receive their 10 to 14 years old child asking for fruits and vegetables (FV). An online parenting style questionnaire was completed and follow-up qualitative telephone interviews assessed home food rules, child influence on home food availability, parents' preferences for being asked for food, and common barriers and reactions to their child's FV requests. Parents (n = 73) with a 10 to 14 years old child were grouped into authoritative, authoritarian, permissive, or uninvolved parenting style categories based on responses to questionnaires, and interviewed. Almost no differences in responses were detected by parenting style or ethnicity. Parents reported their children had a voice in what foods were purchased and available at home and were receptive to their child's asking for FV. The most important child asking characteristic was politeness, especially among authoritarian parents. Other important factors were asking in person, helping in the grocery store, writing requests on the grocery shopping list, and showing information they saw in the media. The barrier raising the most concern was FV cost, but FV quality and safety outside the home environment were also considerations.

  7. Networks of Food Sharing Reveal the Functional Significance of Multilevel Sociality in Two Hunter-Gatherer Groups.

    Science.gov (United States)

    Dyble, Mark; Thompson, James; Smith, Daniel; Salali, Gul Deniz; Chaudhary, Nikhil; Page, Abigail E; Vinicuis, Lucio; Mace, Ruth; Migliano, Andrea Bamberg

    2016-08-01

    Like many other mammalian and primate societies [1-4], humans are said to live in multilevel social groups, with individuals situated in a series of hierarchically structured sub-groups [5, 6]. Although this multilevel social organization has been described among contemporary hunter-gatherers [5], questions remain as to the benefits that individuals derive from living in such groups. Here, we show that food sharing among two populations of contemporary hunter-gatherers-the Palanan Agta (Philippines) and Mbendjele BaYaka (Republic of Congo)-reveals similar multilevel social structures, with individuals situated in households, within sharing clusters of 3-4 households, within the wider residential camps, which vary in size. We suggest that these groupings serve to facilitate inter-sexual provisioning, kin provisioning, and risk reduction reciprocity, three levels of cooperation argued to be fundamental in human societies [7, 8]. Humans have a suite of derived life history characteristics including a long childhood and short inter-birth intervals that make offspring energetically demanding [9] and have moved to a dietary niche that often involves the exploitation of difficult to acquire foods with highly variable return rates [10-12]. This means that human foragers face both day-to-day and more long-term energetic deficits that conspire to make humans energetically interdependent. We suggest that a multilevel social organization allows individuals access to both the food sharing partners required to buffer themselves against energetic shortfalls and the cooperative partners required for skill-based tasks such as cooperative foraging.

  8. Real-Space Renormalization Group for Quantum Gravity I: Significance of terms linear and quadratic in curvature

    CERN Document Server

    Sharatchandra, H S

    2016-01-01

    Real-Space renormalization group techniques are developed for tackling large curvature fluctuations in quantum gravity. Within cells of invariant volume $a^4$, only certain types of fluctuations are allowed. Normal coordinates are used to avoid redundancy of the degrees of freedom. The relevant integration measure is read off from the metric on metrics. All fluctuations in a group of cells are averaged over to get an effective action for the larger cell. In this paper the simplest type of fluctuations are kept. The measure is simply an integration over independent components of the curvature tensor at the center of each cell. Terms of higher order in $a$ are required for convergence in case of Einstein-Hilbert action. With only next order (in $a$) contribution to the action, there is no renormalization of Newton's or cosmological constants. The `massless Gaussian surface' in the renormalization group space is given by actions that have linear and quadratic terms in curvature and determines the evolution of co...

    The Kets, an ethnic group in the Yenisei River basin, Russia, are considered the last nomadic hunter-gatherers of Siberia, and Ket language has no transparent affiliation with any language family. We investigated connections between the Kets and Siberian and North American populations, with emphasis on the Mal'ta and Paleo-Eskimo ancient genomes, using original data from 46 unrelated samples of Kets and 42 samples of their neighboring ethnic groups (Uralic-speaking Nganasans, Enets, and Selkups). We genotyped over 130,000 autosomal SNPs, identified mitochondrial and Y-chromosomal haplogroups, and performed high-coverage genome sequencing of two Ket individuals. We established that Nganasans, Kets, Selkups, and Yukaghirs form a cluster of populations most closely related to Paleo-Eskimos in Siberia (not considering indigenous populations of Chukotka and Kamchatka). Kets are closely related to modern Selkups and to some Bronze and Iron Age populations of the Altai region, with all these groups sharing a high degree of Mal'ta ancestry. Implications of these findings for the linguistic hypothesis uniting Ket and Na-Dene languages into a language macrofamily are discussed.

    2007-01-01

    Sixty-two geologically meaningful U-Pb dates were obtained by using SHRIMP technique for the detrital zircons in three mettasedimentary rocks from stratigraphically uppermost parts of the Longshoushan Group in the present study.Eighty percents of these dates range from 1.7 Ga to 2.2 Ga with a peak at 1.8-2.0 Ga and twenty percents from 2.3 Ga to 2.7 Ga.The youngest detrital zircon is dated at 1724±19Ma which is interpreted as the maximum depositional age of the metasedimentary rocks.Therefore,the age for the diagenesis and lithification of the original sedimentary rocks of the Longshoushan Group before the metamorphism must be younger than 1724±19 Ma.Comparison of the age histograms of these detrital zircons with the ages of the igneous rocks on the surrounding older massifs suggests that the sediments of the Longshoushan Group were most likely derived from the Alaxa Block and Tarim Craton.This implies that the affinity between Alaxa Block and Tarim Craton was strong and that they might have been a unified craton during middle-early Proterozoic time

  12. Permian bivalves of the Taciba Formation, Itararé Group, Paraná Basin, and their biostratigraphic significance

    Directory of Open Access Journals (Sweden)

    Marcello Guimarães Simões

    2012-04-01

    Full Text Available A small and poorly diversified bivalve fauna from Taciba Formation, Itararé Group, Paraná Basin (State of Santa Catarina,Mafra Municipality, is described in this paper for the first time, based on new findings. The fauna is recorded in a 30 cmthick interval of fine sandstone locally at the top of Taciba Formation, in the Butiá quarry. The studied fossil-bearing sandstonebed is a marine intercalation recording a brief eustatic rise in sea-level, probably following glacier retreat and climateamelioration at the end of a broad glacial scenario. The fauna is mainly dominated by productid brachiopods, which are notdescribed here, and rare mollusk shells (bivalves and gastropods. Two bivalve species were identified: Myonia argentinensis(Harrington, 1955, and Aviculopecten multiscalptus (Thomas, 1928. The presence of Myonia argentinensis is noteworthysince this species is also present in the Baitaca assemblage found in marine siltstones (Baitaca assemblage of theRio do Sul Formation, cropping out at the Teixeira Soares region, Paraná State. This species is also recorded in the bivalvefauna from the Bonete Formation, Pillahinco Group, Sauce Grande Basin, Buenos Aires Province, in Argentina. Hence, themarine bivalves of the Taciba Formation are associated with the transgressive event that characterizes the Eurydesma fauna,indicating a Late Asselian-Sakmarian age for the bivalve fauna. Presence of the Myonia argentinensis megadesmid speciesreinforces the Gondwanic nature of the studied fauna.

  13. Occurrence of helically coiled microfossil Obruchevella in the Owk Shale of the Kurnool Group and its significance

    Mukund Sharma; Yogmaya Shukla

    2012-06-01

    The present study reports occurrence of helically coiled microfossil Obruchevella Reitlinger from the Owk Shale of the Kurnool Group from the peninsular India. The age of the Kurnool Group is poorly constrained due to the absence of direct radiometric dating and meager palaeobiological data. Occurrence of Obruchevella is considered as a typical Vendian marker genus recorded mostly from close to the Precambrian–Cambrian boundary successions. Hence, the present assemblage is important to ascertain the age of the basin. In the Owk Shale, four species of Obruchevella, viz., O. delicata, O. parva, O. minor and O. valdaica are recorded as organic walled microfossils. Among them O. valdaica is the largest in terms of size parameters. On the global scale, the recovered species occur in the Late Neoproterozoic to Early Cambrian sediments. Therefore, the occurrence of microfossil Obruchevella in the Owk Shale and known burrow structures in the Narji Limestone suggest Ediacaran age close to the Cambrian for the Kurnool Basin and challenges the recently assigned esoproterozoic age of the basin.

    p38 mitogen-activated protein kinase (MAPK) signaling promotes diabetic kidney injury. Apoptosis signal-regulating kinase (ASK)1 is one of the upstream kinases in the p38 MAPK-signaling pathway, which is activated by inflammation and oxidative stress, suggesting a possible role for ASK1 in diabetic nephropathy. In this study, we examined whether a selective ASK1 inhibitor can prevent the induction and progression of diabetic nephropathy in mice. Diabetes was induced in hypertensive endothelial nitric oxide synthase (Nos3)-deficient mice by five low-dose streptozotocin (STZ) injections. Groups of diabetic Nos3(-/-) mice received ASK1 inhibitor (GS-444217 delivered in chow) as an early intervention (2-8 weeks after STZ) or late intervention (weeks 8-15 after STZ). Control diabetic and nondiabetic Nos3(-/-) mice received normal chow. Treatment with GS-444217 abrogated p38 MAPK activation in diabetic kidneys but had no effect upon hypertension in Nos3(-/-) mice. Early intervention with GS-444217 significantly inhibited diabetic glomerulosclerosis and reduced renal dysfunction but had no effect on the development of albuminuria. Late intervention with GS-444217 improved renal function and halted the progression of glomerulosclerosis, renal inflammation, and tubular injury despite having no effect on established albuminuria. In conclusion, this study identifies ASK1 as a new therapeutic target in diabetic nephropathy to reduce renal inflammation and fibrosis independent of blood pressure control. © 2015 by the American Diabetes Association.

    2017-03-01

    Women are less likely to reach top-level leadership positions, and more likely to leave academic positions, than men, and are likely to earn less money than men. Women are also less likely to initiate a negotiation-a process that is crucial for professional advancement. This reluctance to ask hinders their advancement and can have long-lasting consequences-both financial and professional. The reasons that women do not ask are multifactorial. In this article, we will explore reasons why women are less likely to negotiate, the barriers they face when they do, and strategies that women can apply to improve their negotiation skills.

  17. On the significance of the anchoring group in the design of antenna materials based on phthalocyanine stopcocks and zeolite L.

    The synthesis of stopcocks based on zinc phthalocyanine for selective adsorption at the channel entrances of zeolite L is reported. The introduction of either an inert SiMe₃ moiety, an imidazolium cation or a reactive isothiocyanate (NCS) group allows attachment to the channel entrances of zeolite L through van der Waals interactions, electrostatic interactions, or covalent binding, respectively. Stopcocks that rely on van-der-Waals-driven adsorption require careful selection of the solvent used for the deposition onto the zeolite surface to avoid a nonspecific distribution of the molecules. Regarding the design of photonic antenna systems, a stopcock with a cationic tail was found to be the most convenient, based on the observation that efficient energy transfer from molecules located in the zeolite nanochannels is more readily obtained than in the other cases.

  18. [The difficult concept of "internal objects" (1934-1943). Its significance for the formation of the Klein group].

    Science.gov (United States)

    Hinshelwood, R D

    1996-06-01

    Although the concept of "inner objects" developed by Melanie Klein is hardly a major object of discussion today, it caused a furore in the ranks of the British Psychoanalytical Society in the thirties and forties. Notably the analysts from Vienna were unable to agree to the existence of inner objects engendered via processes of internalisation. The author traces the course of these discussions of a clinical problem and the confusion they caused, placing them at the same time in a specific historical context. He sees the controversy as the expression of conflicts and fears unsettling the British Psychoanalytical Society during that period, caused on the one hand by the necessary integration of the exiled Freud family and on the other by tensions within its own ranks leading ultimately to a division of the Society and the constitution of the Klein Group.

    2011-12-01

    A detailed ichnological study performed on the Bhuban Formation, Surma Group (Lower to Middle Miocene) of Mizoram, India reveals the occurrence of rich and diverse trace fossils. These have been collected from the two localities in Aizawl, i.e., Bawngkawn and Ropaiabawk, where sandstone-shale sequence is well exposed. Total 20 ichnospecies of 14 ichnogenera have been identified which include Arenicolites isp., Cochlichnus anguineus, Helminthopsis abeli, Laevicyclus mongraensis, Ophiomorpha borneensis, Palaeophycus tubularis, Palaeophycus heberti, Palaeophycus sulcatus, Palaeophycus alternatus, Pholeus abomasoformis, Pholeus bifurcatus, Planolites beverleyensis, Planolites annularis, Polykladichnus irregularis, Rhizocorallium isp., Skolithos linearis, Taenidium satanassi, Teichichnus rectus, Thalassinoides horizontalis and Thalassinoides paradoxicus. Ethologically these ichnogenera display dwelling and feeding activities of the infaunal organisms. Arenicolites, Ophiomorpha, Polykladichnus and Skolithos are the members of the Skolithos ichnofacies while Palaeophycus, Planolites, Rhizocorallium and Thalassinoides are the members of the Cruziana ichnofacies. The presence of Skolithos ichnofacies indicates sandy shifting substrate and high energy conditions in foreshore zone while the Cruziana ichnofacies indicate unconsolidated, poorly sorted soft substrate and low energy condition in the shoreface/offshore zone. These ichnogenera indicate foreshore to shoreface-offshore zone of shallow marine environment for the deposition of the rocks of the Bhuban Formation of Mizoram.

  20. Formation and geochemical significance of micrometallic aggregates including fissiogenic platinum group elements in the Oklo natural reactor, Gabon

    Science.gov (United States)

    Kikuchi, Makiko; Hidaka, Hiroshi; Gauthier-Lafaye, François

    2010-08-01

    Metallic aggregates with a size of a few tens μm and consisting mainly of Ru, Rh, Pd, Te, Pb, As, Sb, S and Bi were found in the acid residue of SD37-S2/CD uraninite taken from Oklo natural reactor zone (RZ) 13. Quantitative analyses of major elements using an electron probe microanalyzer and in situ isotopic analyses of Zr, Mo, Ru, Pb and U using a sensitive high-resolution ion microprobe were performed on the metallic aggregates to determine the geochemical behaviors of fission products and actinides and to ascertain the processes of formation of the aggregates in the RZs. The chemical compositions of the aggregates investigated in this study are significantly different from those reported previously, showing lower Pb content and no correlation between the contents of Pb and S in the individual grains. The 235U/ 238U ratios in metallic aggregates vary significantly from 0.00478 to 0.01466, indicating chemical fractionation between U and Pu during the formation of the aggregates. The Pb isotopic data indicate that most of the Pb in the aggregates decayed from 2.05 Ga-old uraninite that existed in the RZ originally and that there was chemical fractionation between U and Pb in some aggregates. The Zr and Mo isotopic ratios, 90Zr/ 91Zr and 95Mo/ 97Mo, for most of the aggregates had small variations, which can be simply explained by constant separate mixing of fissiogenic and nonfissiogenic components. On the other hand, a large variation in the 99Ru/ 101Ru ratio (0.324-1.73) cannot be explained only by a two component mixing theory; thus, chemical fractionation between Tc and Ru during the reactor criticality is suggested. The large variations in the 235U/ 238U and 99Ru/ 101Ru isotopic ratios suggest that the aggregates formed under various redox conditions owing to the radiolysis of water.

Our intention is to give a simple introduction to the physics of gases that would be helpful for newcomers to the field of hypoxia research. We will provide background knowledge about questions often asked, but without straightforward answers. What is O2 concentration, and what is O2 partial pressure? What is normoxia, and what is hypoxia? How much O2 is experienced by a cell residing in a culture dish in vitro vs in a tissue in vivo? By the way, the O2 concentration in a normoxic incubator is 18.6%, rather than 20.9% or 20%, as commonly stated in research publications. And this is strictly only valid for incubators at sea level. Keywords: gas laws, hypoxia-inducible factor, Krogh tissue cylinder, oxygen diffusion, partial pressure, tissue oxygen levels

  14. Frequently asked questions about global modeling

    2009-06-01

    When a global model is attempted from experimental data, some preprocessing might be required. Therefore it is only natural to wonder what kind of effects the preprocessing might have on the modeling procedure. This concern is manifested in the form of recurrent frequently asked questions, such as "how does the preprocessing affect the underlying dynamics?" This paper aims at providing answers to important questions related to (i) data interpolation, (ii) data smoothing, (iii) data-estimated derivatives, (iv) model structure selection, and (v) model validation. The answers provided will hopefully remove some of those doubts and one shall be more confident not only on global modeling but also on various data analyses which may be also dependent on data preprocessing.

    This prospective study aimed to investigate the influence of pretransplant serum ferritin levels on the outcomes of allogeneic hematopoietic SCT (HSCT). In total, 190 patients with acute leukemia or myelodysplastic syndrome were consecutively enrolled. The patients were divided into two groups: low-ferritin group (ferritin group (⩾1000 ng/mL). The primary end point was the cumulative incidence of infection within 100 days after HSCT, which was similar between the two groups: bloodstream infection, 35 vs 38%, P=0.65; bacterial infection, 44 vs 41%, P=0.68; and fungal infection, 6 vs 8%, P=0.71. The 1-year adjusted probability of OS of the high-ferritin group was significantly lower than that of the low-ferritin group (76 vs 63%, P=0.017). Using receiver operating characteristic curve, the threshold of pretransplant serum ferritin levels for bloodstream infection was 1400 ng/mL; the threshold for OS, EFS and non-relapse mortality was 1349 ng/mL. In conclusion, pretransplant serum ferritin levels of ⩾1000 ng/mL did not influence the incidence of infection but adversely affected OS after HSCT. A higher threshold of pretransplant serum ferritin levels may predict HSCT outcomes.

    Quality of life in patients with vitiligo is impaired. This study explored the immediate effect of 20 days of climatotherapy at the Dead Sea on quality of life, coping with the disease, general well-being and individual stress levels in a group of 71 patients with vitiligo and 42 matched controls. The long-term effect was assessed after 12 months in 33/71 patients and 12/42 controls. Study instruments were Dermatology Life Quality Index, Beck Depression Inventory and the Adjustment to Chronic Skin Disorders Questionnaire. Stress measurements were based on cortisol and β-endorphin concentrations in saliva samples. Quality of life was significantly improved at day 20 at the Dead Sea compared with day 1, and this was still significant after 12 months. Moreover, social anxiety/avoidance, anxious-depressive mood and helplessness as measured by the Adjustment to Chronic Skin Disorders Questionnaire were significantly reduced. There was no difference in levels of cortisol and β-endorphin between patients and controls, indicating that stress per se is not a significant contributor in vitiligo. In conclusion, therapy in patient groups offers an effective tool for long-lasting improvement in quality of life and patients' well-being.

    CYP2E1 PstI polymorphism G-1259C (rs3813867) genotype distributions vary significantly among different populations and are associated with both diseases, like cancer, and adverse drug effects. To date, there have been limited genotype distributions and allele frequencies of this polymorphism reported in the three major indigenous ethnic groups (KadazanDusun, Bajau, and Rungus) in Sabah, also known as North Borneo. The aim of this study was to investigate the genotype distributions and allele frequencies of the CYP2E1 PstI polymorphism G-1259C in these three major indigenous peoples in Sabah. A total of 640 healthy individuals from the three dominant indigenous groups were recruited for this study. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) at G-1259C polymorphic site of CYP2E1 gene was performed using the Pst I restriction enzyme. Fragments were analyzed using agarose gel electrophoresis and confirmed by direct sequencing. Overall, the allele frequencies were 90.3% for c1 allele and 9.7% for c2 allele. The genotype frequencies for c1/c1, c1/c2 and c2/c2 were observed as 80.9%, 18.8%, and 0.3%, respectively. A highly statistical significant difference (ppopulations. However, among these three indigenous groups, there was no statistical significant difference (p>0.001) in their genotype distributions. The three major indigenous ethnic groups in Sabah show unique genotype distributions when compared with other populations. This finding indicates the importance of establishing the genotype distributions of CYP2E1 PstI polymorphism in the indigenous populations.

  12. I Wish I'd Asked That: The Culture of Asking Questions in Astronomy

    Science.gov (United States)

    Baleisis, Audra

    2009-01-01

    I will present the results from a qualitative study of the values and norms for thinking about science in academic astronomy, as seen through astronomers’ beliefs about departmental speech events. In-depth interviews were carried out with 12 graduate students and 9 faculty members from a prominent astronomy department at a large, public university. Interviewees were asked about a variety of speaking events in their department. The speaking events chosen were those at which: (1) graduate students could be presenters and/or ask questions, and (2) presenters spoke about science research to an audience of academic peers. This included Coffee Hour, Journal Club, research seminars, Colloquium, and dissertation defense talks. These events are part of the socialization of students into "acting like an astronomer.” Socialization is a process by which novices learn the rules (can and can't do), norms (should and shouldn't do), and values of a culture. The values of astronomy culture are encoded within the rules for participation in these events and the assumptions that audience members make about speakers. When these values contradict each other speakers face the dilemma of choosing between conflicting behaviors. One of the central dilemmas that arose in this study was that of whether or not to ask a question during a talk. Both graduate students and faculty members wanted students to speak up more often. However, students had conflicting worries - of voicing a question and it being a "stupid question” vs. having remained silent if it turned out to have been a "good question.” I will argue that this anxiety is a product of academic culture and not an indicator of individual failure, and discuss a number of factors that influence this situation, such as the perceived goals of each event, and astronomers’ beliefs about intelligence and learning.

    1. The technique of glycogen depletion was used to determine whether regenerating motor axons reestablish the normal regionalization of motor units (MUs) in the cat medial gastrocnemius (MG) muscle, 2) whether the extent of clumping between MU fibers and/or type grouping of muscle fibers progressively increases with a decrease in reinnervated MU numbers, and 3) whether the pattern of innervation can explain why MUs fail to increase significantly in size when the cut nerve is sutured directly to the muscle, even when few axons make functional connections. 2. Distributions of MU fibers were analyzed in 5 normal and 14 reinnervated cat MG muscles 4.5-16 mo after sectioning of its nerve and suturing of the proximal end to the distal nerve sheaths (N-N suture) or directly to the muscle fascia (N-M suture). Muscle unit distributions were quantified according to location, territory size, density, and extent of clumping between fibers from the same MU. 3. Normal MU fibers were regionalized within five regions along the muscle's longitudinal and transverse axes. Reinnervated MUs were located within similar regions, indicating that regenerating axons follow the major proximal nerve branches to restore normal compartmentalization. 4. Muscle unit fibers were diffusely scattered within discrete MU territories in normal muscles. Territory size tended to increase with MU size, whereas density of muscle unit fibers within the territory decreased. 5. Territories increased with MU size after N-N suture but were smaller and showed little size variation after N-M suture. The extent of muscle unit fiber clumping was inversely related to the number of reinnervated MUs. On average, the extent of clumping was substantially higher in muscles reinnervated after N-M suture. These results indicate that distal nerve sheaths facilitate proximal axon branching, which establishes MU territory size. Once the territory is established, motor axons branch distally to increase MU size, which in turn

    To investigate both the prevalence and clinical characteristics of serositis in Chinese patients with systemic lupus erythematosus (SLE) in a large cohort in the Chinese SLE Treatment and Research group (CSTAR) database. A prospective cross-sectional study of patients with SLE was conducted based on the data from the CSTAR registry. Serositis was defined according to the 1999 revised American College of Rheumatology (ACR) criteria for SLE - that is, pleuritis/pleural effusion and/or pericarditis/pericardial effusion detected by echocardiography, chest X-ray or chest computerized tomography (CT) scan. Peritonitis/peritoneal effusion were confirmed by abdominal ultrasonography. We analysed the prevalence and clinical associations of serositis with demographic data, organ involvements, laboratory findings and SLE disease activity. Of 2104 patients with SLE, 345 were diagnosed with serositis. The prevalence of lupus nephritis (LN), interstitial lung disease and pulmonary arterial hypertension, as well as the presence of leukocytopenia, thrombocytopenia, hypocomplementemia and anti-dsDNA antibodies was significantly higher in patients with serositis (P Lupus-related peritonitis had similar clinical manifestations and laboratory profiles as serositis caused by SLE. There is a significant association of nephropathy, interstitial lung disease, pulmonary arterial hypertension, hypocomplementemia, leukocytopenia, thrombocytopenia and elevated anti-dsDNA antibodies with serositis. The results suggest that higher SLE disease activity contributes to serositis development, and should be treated aggressively. © The Author(s) 2016.

    sedimentation contributed to the bands (or lamellars) with minerals of much smaller grain size, which therefore resulted in diversities from the other bands (or lamellars). According to this, the repeated bands (or lamellars) denoted the volcanic activities were cyclic during the formation of the chert. What's more, the carbonate vein came from the precipitation of subsequent hydrothermal fluids in the fracture of the chert, which contributed to the changes (e. g. rising in crystallinity degree of silica and formation of micro-structure of new silicate) near the interface between chert and the carbonate vein. Although there were many impurity minerals with complex genesis, the relatively lower content of silica in the chert of Xionger Group was due to the volcanic mineral mainly. Since there were impurity minerals of volcanic genesis in relatively large amount, the content of silica in the chert of Xionger Group was hence relatively low. In this study, the Raman analysis was witnessed to be an effective way in the researches on the chert, and could open out the type of mineral, micro-structure and degrees of crystallinity (or order). These characteristics were well kept in the micro-area, and played significant roles to reflect and understand the formation mechanism and subsequent evolution of the chert.

    2012-06-01

    Full Text Available Abstract Background Intimate partner violence (IPV against women is a serious public health issue and is associated with significant adverse health outcomes. The current study was undertaken to: 1 explore physicians’ and nurses’ experiences, both professional and personal, when asking about IPV; 2 determine the variations by discipline; and 3 identify implications for practice, workplace policy and curriculum development. Methods Physicians and nurses working in Ontario, Canada were randomly selected from recognized discipline-specific professional directories to complete a 43-item mailed survey about IPV, which included two open-ended questions about barriers and facilitators to asking about IPV. Text from the open-ended questions was transcribed and analyzed using inductive content analysis. In addition, frequencies were calculated for commonly described categories and the Fisher’s Exact Test was performed to determine statistical significance when examining nurse/physician differences. Results Of the 931 respondents who completed the survey, 769 (527 nurses, 238 physicians, four whose discipline was not stated provided written responses to the open-ended questions. Overall, the top barriers to asking about IPV were lack of time, behaviours attributed to women living with abuse, lack of training, language/cultural practices and partner presence. The most frequently reported facilitators were training, community resources and professional tools/protocols/policies. The need for additional training was a concern described by both groups, yet more so by nurses. There were statistically significant differences between nurses and physicians regarding both barriers and facilitators, most likely related to differences in role expectations and work environments. Conclusions This research provides new insights into the complexities of IPV inquiry and the inter-relationships among barriers and facilitators faced by physicians and nurses. The

  1. Significance of PIK3CA Mutations in Patients with Early Breast Cancer Treated with Adjuvant Chemotherapy: A Hellenic Cooperative Oncology Group (HeCOG Study.

    Full Text Available The PI3K-AKT pathway is frequently activated in breast cancer. PIK3CA mutations are most frequently found in the helical (exon 9 and kinase (exon 20 domains of this protein. The aim of the present study was to examine the role of different types of PIK3CA mutations in combination with molecular biomarkers related to PI3K-AKT signaling in patients with early breast cancer.Tumor tissue samples from 1008 early breast cancer patients treated with adjuvant chemotherapy in two similar randomized trials of HeCOG were examined. Tumors were subtyped with immunohistochemistry (IHC and FISH for ER, PgR, Ki67, HER2 and androgen receptor (AR. PIK3CA mutations were analyzed by Sanger sequencing (exon 20 and qPCR (exon 9 (Sanger/qPCR mutations. In 610 cases, next generation sequencing (NGS PIK3CA mutation data were also available. PIK3CA mutations and PTEN protein expression (IHC were analyzed in luminal tumors (ER and/or PgR positive, molecular apocrine carcinomas (MAC; ER/PgR negative / AR positive and hormone receptor (ER/PgR/AR negative tumors.PIK3CA mutations were detected in 235/1008 tumors (23% with Sanger/qPCR and in 149/610 tumors (24% with NGS. Concordance between the two methods was good with a Kappa coefficient of 0.76 (95% CI 0.69-0.82. Lobular histology, low tumor grade and luminal A tumors were associated with helical domain mutations (PIK3CAhel, while luminal B with kinase domain mutations (PIK3CAkin. The overall incidence of PIK3CA mutations was higher in luminal as compared to MAC and hormone receptor negative tumors (p = 0.004. Disease-free and overall survival did not significantly differ with respect to PIK3CA mutation presence and type. However, a statistically significant interaction between PIK3CA mutation status and PTEN low protein expression with regard to prognosis was identified.The present study did not show any prognostic significance of specific PIK3CA mutations in a large group of predominantly lymph-node positive breast cancer

  2. Refugees' advice to physicians: how to ask about mental health.

    Shannon, Patricia J

    2014-08-01

    About 45.2 million people were displaced from their homes in 2012 due to persecution, political conflict, generalized violence and human rights violations. Refugees who endure violence are at increased risk of developing chronic psychiatric disorders such as posttraumatic stress disorder and major depression. The primary care visit may be the first opportunity to detect the devastating psychological effects of trauma. Physicians and refugees have identified communication barriers that inhibit discussions about mental health. In this study, refugees offer advice to physicians about how to assess the mental health effects of trauma. Ethnocultural methodology informed 13 focus groups with 111 refugees from Burma, Bhutan, Somali and Ethiopia. Refugees responded to questions concerning how physicians should ask about mental health in acceptable ways. Focus groups were recorded, transcribed and analyzed using thematic categorization informed by Spradley's Developmental Research Sequence. Refugees recommended that physicians should take the time to make refugees comfortable, initiate direct conversations about mental health, inquire about the historical context of symptoms and provide psychoeducation about mental health and healing. Physicians may require specialized training to learn how to initiate conversations about mental health and provide direct education and appropriate mental health referrals in a brief medical appointment. To assist with making appropriate referrals, physicians may also benefit from education about evidence-based practices for treating symptoms of refugee trauma. © The Author 2014.

    In 2003, following a workshop at the National Institutes of Health, the International Restless Legs Syndrome Study Group (IRLSSG) developed updated diagnostic criteria for restless legs syndrome/Willis-Ekbom disease (RLS/WED). These criteria were integral to major advances in research, notably in epidemiology, biology, and treatment of RLS/WED. However, extensive review of accumulating literature based on the 2003 NIH/IRLSSG criteria led to efforts to improve the diagnostic criteria further. The clinical standards workshop, sponsored by the WED Foundation and IRLSSG in 2008, started a four-year process for updating the diagnostic criteria. That process included a rigorous review of research advances and input from clinical experts across multiple disciplines. After broad consensus was attained, the criteria were formally approved by the IRLSSG executive committee and membership. Major changes are: (i) addition of a fifth essential criterion, differential diagnosis, to improve specificity by requiring that RLS/WED symptoms not be confused with similar symptoms from other conditions; (ii) addition of a specifier to delineate clinically significant RLS/WED; (iii) addition of course specifiers to classify RLS/WED as chronic-persistent or intermittent; and (iv) merging of the pediatric with the adult diagnostic criteria. Also discussed are supportive features and clinical aspects that are important in the diagnostic evaluation. The IRLSSG consensus criteria for RLS/WED represent an international, interdisciplinary, and collaborative effort intended to improve clinical practice and promote further research.

    1998-01-01

    We examined whether motivational procedures incorporated into teaching question-asking to children with autism, who lack verbal initiations, would result in generalization without additional teaching, prompting, or reinforcement in other settings. Specifically, we assessed whether such children could learn to use questions and whether the spontaneous use of question-asking would generalize across stimuli, settings, and people. All children learned to use questions in relation to items they had previously been unable to label and demonstrated generalization of spontaneous question-asking to new items and to their home environments with their mothers, with concomitant gains in expressive vocabulary. Results were discussed in terms of teaching response strategies, such as question-asking, to promote spontaneous child-initiated social interactions and expressive language development.

    The value model discussed herein provides an accurate and simple calculation of the funding required to adequately staff the AskIT Service Desk (SD).  The model is incremental – only technical labor cost is considered.  All other costs, such as management, equipment, buildings, HVAC, and training are considered common elements of providing any labor related IT Service. Depending on the amount of productivity loss and the number of hours the defect was unresolved, the value of resolving work from the SD is unquestionably an economic winner; the average cost of $16 per SD resolution can commonly translate to cost avoidance exceeding well over $100. Attempting to extract too much from the SD will likely create a significant downside. The analysis used to develop the value model indicates that the utilization of the SD is very high (approximately 90%).  As a benchmark, consider a comment from a manager at Vitalyst (a commercial IT service desk) that their utilization target is approximately 60%.  While high SD utilization is impressive, over the long term it is likely to cause unwanted consequences to staff such as higher turnover, illness, or burnout.  A better solution is to staff the SD so that analysts have time to improve skills through training, develop knowledge, improve processes, collaborate with peers, and improve customer relationship skills.

    The aim of this pilot study was to investigate the feasibility and effectiveness of a new psychoeducative intervention program (PEGASUS) for adults with ADHD and their significant others in a psychiatric outpatient context. At three outpatient psychiatric clinics, adults with ADHD and their significant others took part in PEGASUS, a psychoeducational program based on theories from cognitive behavioral therapy, neuropsychology, and cross-disciplinary evidence regarding ADHD. In total, 108 adults were allocated to treatment (51 with ADHD and their 57 significant others). Feasibility was evaluated regarding suitability of the intervention at a psychiatric outpatient clinic and treatment completion. Preliminary efficacy was evaluated per protocol from baseline to post-intervention (n = 41 adults with ADHD and 40 significant others). In a feasibility analysis, the intervention was judged to be a suitable treatment option for 94.5 % of all individuals with a primary diagnosis of ADHD at an outpatient psychiatric clinic. In total, 43 out of 51 allocated individuals with ADHD (84.3 %) completed the intervention. The corresponding figures for their significant others were 42 out of 57 (73.7 %). Knowledge about ADHD increased, and both the quality of relationships and psychological well-being improved from baseline to post-intervention in all participants. The significant others reported a reduction in the subjective burden of care, such as worry and guilt. The objective burden of care (such as financial problems) did not change. The findings support the potential value of psychoeducation for adults with ADHD and their significant others. An ongoing randomized controlled trial will generate further evidence concerning the PEGASUS program.

    2003-06-01

    Physiotherapy is a frequently applied concomitant therapy for patients with osteoporosis. Compared to modern pharmacological therapy physiotherapy appears to receive sustained high regard, which should be further examined in view of the attribution pattern of the patients. Elements of physiotherapy and Kneipp therapy were quantitatively examined in terms of their semantic content in a three-dimensional space of meaning. This was done in comparison with elements of modern pharmacological therapy. The questions regarding possible patterns of the attributions and a possible hierarchy of the therapy forms were analyzed by a survey of a self-help group for osteoporosis patients and two control groups. According to the methods of semantic differentials, a self-help group for osteoporosis patients and two control groups (high-school female pupils, breast carcinoma patients) were queried about the individual elements of physiotherapy and modern pharmacological therapy in a polar profile of a questionnaire. The results were arranged onto a numerical matrix and by means of factor analysis, a location in a three-dimensional space of meaning was calculated for each element questioned. For purpose of illustration, the results were transferred to a succession of diagrams so that the assessments for the three axes of meaning became more distinct. The results are discussed on the background of a current neurolinguistic theory of meaning: Sensomotoric experience generates meaning in form of 'primary metaphors'; if reactivated e.g. by physiotherapy, these metaphors can give fundaments for an emergent and salutogenic system of meaning, which helps to reconstruct the patient's 'subjective anatomy' and helps to create new values of living one's life. If sensomotoric experience has a central function in generating meaning, the axis of 'motion' and therapies stressing on sensomotoric experience (e.g. exercise group) will show a corresponding profile of evaluation throughout the three

  1. Using chi-Squared Automatic Interaction Detection (CHAID) modelling to identify groups of methadone treatment clients experiencing significantly poorer treatment outcomes.

    2013-10-01

    In times of scarce resources it is important for services to make evidence based decisions when identifying clients with poor outcomes. chi-Squared Automatic Interaction Detection (CHAID) modelling was used to identify characteristics of clients experiencing statistically significant poor outcomes. A national, longitudinal study recruited and interviewed, using the Maudsley Addiction Profile (MAP), 215 clients starting methadone treatment and 78% were interviewed one year later. Four CHAID analyses were conducted to model the interactions between the primary outcome variable, used heroin in the last 90 days prior to one year interview and variables on drug use, treatment history, social functioning and demographics. Results revealed that regardless of these other variables, males over 22 years of age consistently demonstrated significantly poorer outcomes than all other clients. CHAID models can be easily applied by service providers to provide ongoing evidence on clients exhibiting poor outcomes and requiring priority within services.

  2. Petrology and palaeoenvironmental significance of authigenic iron-rich clays, carbonates and apatite in the Claiborne Group, Middle Eocene, NE Texas

    The Claiborne Group (Eocene) in North East Texas consists of clayey sandstones and mudrocks, both with variable proportions of dark green to brown clay pellets deposited in a marginal to open marine setting on the Gulf Coast margin. The composition of concretionary carbonate and clay pellets, from 5 localities, has been investigated using a wide variety of analytical techniques. Our palaeontological, sedimentological, C/S and stable isotope data support an interpretation of marginal marine facies with limited freshwater input, for the Claiborne Group. Dark green (mature) pellets are predominantly associated with transgressive, bioturbated, marine sediments. From the Weches Formation through to the youngest Crockett Formation there is a trend from pellets composed mostly of dark green serpentine-rich mixed layer clay to those of mostly brown (immature) nontronite-rich mixed layer clay. The serpentine is intermediate between odinite and berthierine and may have been originally odinite that has undergone partial transformation to berthierine. Pellet maturity apparently corresponds with the degree of winnowing and sedimentation rate. It does not appear to correspond with global temperature fluctuations, though the serpentine-rich rather than glauconite-rich composition may do. Siderite cement, mostly in the form of concretions, post-dates the iron-rich clay pellets and pre-dates calcite cement. Carbonate and apatite concretions show a wide range of mineral cement textures, reflecting variation in sedimentary environment and early diagenetic processes. Based on water temperatures derived from verneriacardia bivalves a precipitation temperature of 20 °C is assumed for the concretionary siderite. Using this temperature we surmise that the siderite precipitated from marine pore waters with intermittent meteoric water mixing.

  3. Clinical significance of hTERC and C-Myc genes amplification in a group of Egyptian patients with cancer cervix.

    Cervical cancer is the second most common cancer in women worldwide after breast cancer. Cervical cancer is a preventable disease. The implementation of cervical cancer screening programs has greatly decreased the morbidity and mortality, as precancerous lesions and early invasive cervical cancer could be detected and treated effectively. The detection of hTERC gene amplification was suggested as a possible diagnostic marker for use in routine cytological screening. The present study was designed to detect genomic gains of the hTERC and C-MYC genes using FISH technique and to investigate the relationship between genes amplification and the clinical data of the patients. The current study was carried out on twelve cases with cervical cancer at different grades (three cases were grade I, six cases were grade II and three cases were grade III). Interphase FISH analysis using LSI probe, Cervical Cancer probe hTERC (3q26) & C-MYC (8q24), was successfully performed on 12 patients with cancer cervix. Interphase FISH analysis revealed positive hTERC gene amplification in all cases of cancer cervix (100%). However C-MYC gene amplification was detected in four cases only (33.3%). Statistical analysis of the data revealed significant correlation between hTERC amplification and grading. Also, there was significant correlation between C-MYC amplification and grading and highly significant correlation between C-MYC amplification and hTERC amplification. On the other hand hTERC and C-MYC genes amplification showed an inverse correlation with the ages of the patients. The present study highlights the importance of using hTERC and C-MYC genes FISH probes for cases with cancer cervix or pre-malignant lesions as a sensitive technique. This method provides an easy and effective applicable approach which helps in the diagnosis and prognosis, as an increased copy number is associated with a more advanced grade that could be detected in the early stages of the disease.

  4. Trend arbitrage, bid-ask spread and market dynamics

    2006-01-01

    Microstructure of market dynamics is studied through analysis of tick price data. Linear trend is introduced as a tool for such analysis. Trend arbitrage inequality is developed and tested. The inequality sets limiting relationship between trend, bid-ask spread, market reaction and average update frequency of price information. Average time of market reaction is measured from market data. This parameter is interpreted as a constant value of the stock exchange and is attributed to the latency of exchange reaction to actions of traders. This latency and cost of trade are shown to be the main limit of bid-ask spread. Data analysis also suggests some relationships between trend, bid-ask spread and average frequency of price update process.

    Full Text Available The Araçuaí belt corresponds to the external portion of the western half of the Araçuaí-West Congo Neopro-terozoic orogen. TheAraçuaí belt fringes the São Francisco craton to east and is separated from the crystalline core of the orogen by the Abre Campo geophysical discontinuity. The southern Araçuaí belt involves four major lithologic units: the Archean and Paleoproterozoic gneisses of the Mantiqueira Complex, the Pedra Dourada Charnockite, the Paleoproterozoic Borrachudos Granitoid, and the metavolcanosedimentary rocks of the Dom Silvério Group. The Dom Silvério Group occurs in a NNE-SSW striking belt and consists of a thick package of metapelitic rocks with intercalations of quartzites, amphibolites, meta-ultramafics, banded iron formations, gondites and marbles. All units of the southern Araçuaí belt underwent four syn-metamorphic phases of deformation in the course of the Brasiliano event. The first phase, synchronous to a regional amphibolite facies metamorphism, was associated to a general tectonic transport towards north along the left-lateral Dom Silvério shear zone and its low angle segment. The second and third phases represent progressive stages of a west directed shortening, which led to the development of local thrusts and pervasive folds in several scales. The fourth phase is extensional and reflects the collapse of the orogen.A Faixa Araçuaí corresponde à porção ocidental externa do orógeno neoproterozóico Araçuaí-Congo Ocidental.

    Previous studies have identified healthcare practices that may place undue pressure on related donors (RDs) of hematopoietic cell products and an increase in serious adverse events associated with morbidities in this population. As a result, specific requirements to safeguard RD health have been introduced to Foundation for the Accreditation of Cellular Therapy/The Joint Accreditation Committee ISCT and EBMT (FACT-JACIE) Standards, but the impact of accreditation on RD care has not previously been evaluated. A survey of transplant program directors of European Group for Blood and Marrow Transplantation member centers was conducted by the Donor Health and Safety Working Committee of the Center for International Blood and Marrow Transplant Research to test the hypothesis that RD care in FACT-JACIE accredited centers is more closely aligned with international consensus donor care recommendations than RD care delivered in centers without accreditation. Responses were received from 39% of 304 centers. Our results show that practice in accredited centers was much closer to recommended standards as compared with nonaccredited centers. Specifically, a higher percentage of accredited centers use eligibility criteria to assess RDs (93% versus 78%; P = .02), and a lower percentage have a single physician simultaneously responsible for an RD and their recipient (14% versus 35%; P = .008). In contrast, where regulatory standards do not exist, both accredited and nonaccredited centers fell short of accepted best practice. These results raise concerns that despite improvements in care, current practice can place undue pressure on donors and may increase the risk of donation-associated adverse events. We recommend measures to address these issues through enhancement of regulatory standards as well as national initiatives to standardize RD care.

  8. "This is a question we have to ask everyone": asking young people about self-harm and suicide.

    Science.gov (United States)

    O'Reilly, M; Kiyimba, N; Karim, K

    2016-10-01

    WHAT IS KNOWN ON THE SUBJECT?: An essential part of the mental health assessment is to evaluate the risk of harm to self. Fundamentally this involves asking directly about self-harming behaviour and suicidal thoughts or urges, but practitioners often find it difficult to open up these conversations. This evaluation of risk is particularly important as self-harm and suicidal thoughts are frequently found in young people who attend mental health services. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Young people are not always routinely asked directly about self-harm or suicidal thoughts when they are assessed. There are two ways that mental health practitioners introduce this topic: first, by building up to it by initially asking about general feelings, and second by stating that it is a requirement to ask everyone. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: These questions should not be avoided by mental health practitioners just because they are difficult. We offer suggestions as to how to ask questions about self-harm and suicide based on real-world practice.

    The ASK-IT/Assessing-to-Learn (A2L) project is an attempt to bring a strategic approach to learning, instruction, and communication. ASK-IT/A2L seeks to integrate formative assessment and classroom response system use with physics instruction at both the high school and college levels. In this guide, we present a structure for discussing the new mindset students need in an ASK-IT/A2L classroom, consisting of twelve "habits of mind" for students to develop. To help teachers plan instruction, we present a model of five stages of cognitive development that most students need to follow to develop desirable knowledge and skills. We show how a typical lesson might be organized around "items," the smallest unit of ASK-IT/A2L lesson planning: questions, problems, or tasks given to students to work on individually or in groups. To help with item creation, we present our model-based design paradigm and suggest tips for avoiding common pitfalls and ways to match up cognitive goals with habits of mind. Finally, we apply ...

  10. The effect of different levels of constructive teaching practices on teacher question asking behaviors

    Science.gov (United States)

    Erdogan, Ibrahim

    The purposes of the study were: (1) to examine the effectiveness of the Iowa Chautauqua Professional Development Program (ICPDP) in moving elementary science teachers toward the use of more constructive teaching practices and (2) to investigate the effectiveness of different levels of teaching practices, especially in terms of a sample of teachers achieving "expert" state at the end of program compared with some attaining only with "competent" level. The variables considered were their perceptions of their own classroom practices, stated philosophy of teaching and learning, and their actual classroom practices and question asking behaviors observed via videotape recording. Structured questionnaires, focus group interviews, teacher reflections, and examination of lesson modules were used to collect data from thirty-three K-5 in-service teachers who were involved in a one-year ICPDP. Qualitative and quantitative analyses of data revealed that: (1) Teacher perceptions regarding their teaching and learning, and their actual teaching practices in classroom in terms of constructivist approaches were significantly changed after participation in the ICPDP. (2) Teacher perceptions of their classroom practices and stated philosophies of teaching and learning have a great affect on their actual practices that can be observed. (3) Teacher stated philosophies of teaching and learning significantly influence the quantity and quality of their use of questions in their classrooms. (4) The "expert" teachers accept students' alternative answers and deliberately ask high cognitive level questions that enable students to think critically and to guide them based on what the students are thinking. Alternatively, the "competent" teachers do not follow student responses and used questions which do not help students to understand their current level of understanding nor encourage students to reflect on their own thinking. (5) The role of "expert" teacher is more geared toward challenging

A qualitative content analysis of video-recorded team meetings between team members and caregivers was conducted. In a sample of 12 caregivers in 36 discussions, caregivers asked a total of 137 questions, with the majority being Yes/No questions (45.1%), primarily used to seek clarification (19.6%). Hospice staff asked 396 questions, with the majority consisting of Yes/No questions (66.5%), mainly used to ask about the overall condition of the patient (22.2%). Data from this study suggest that when given the opportunity to participate in hospice team meetings, caregivers will ask questions of hospice staff. In addition, in light of prior research, this study's findings suggest that caregivers may have questions that go unaddressed, specifically regarding pain and medication.

    2016-03-29

    Uncertainty monitoring is a core property of metacognition, allowing individuals to adapt their decision-making strategies depending on the state of their knowledge. Although it has been argued that other animals share these metacognitive abilities, only humans seem to possess the ability to explicitly communicate their own uncertainty to others. It remains unknown whether this capacity is present early in development, or whether it emerges later with the ability to verbally report one's own mental states. Here, using a nonverbal memory-monitoring paradigm, we show that 20-month-olds can monitor and report their own uncertainty. Infants had to remember the location of a hidden toy before pointing to indicate where they wanted to recover it. In an experimental group, infants were given the possibility to ask for help through nonverbal communication when they had forgotten the toy location. Compared with a control group in which infants had no other option but to decide by themselves, infants given the opportunity to ask for help used this option strategically to improve their performance. Asking for help was used selectively to avoid making errors and to decline difficult choices. These results demonstrate that infants are able to successfully monitor their own uncertainty and share this information with others to fulfill their goals.

  4. Survey questions about sleep duration: does asking separately about weekdays and weekends matter?

    Science.gov (United States)

    Lauderdale, Diane S

    2014-03-04

    There is no standard way to ask about sleep duration in surveys, and little is known about the comparability of different questions. This article reports on a randomized survey experiment designed to test 1 type of variation: 1 question about usual sleep hours versus 2 questions separately asking about weekday and weekend sleep. Mean sleep duration was significantly shorter (7.03 hr vs. 7.28 hr) for the single question than a weighted average from 2 questions, and race and ethnicity contrasts differed by question format. Correlations between sleep duration and reported sleep need were significantly higher for the 2-question format. These results demonstrate that question wording can affect reported sleep duration in complicated ways, making it difficult to compare studies that use different questions.

    This thesis aims at investigating what the discourse patterns are in the asking-for-leave notes written by Chinese stu⁃dents and native English speakers respectively and what excuses are given by Chinese students and native English speakers. Role play and retrospective interview were employed as research methords. The results show that the Chinese students all use an induc⁃tive pattern, while all native English speakers write the note in a deductive way. Besides, the excuses presented by the two kinds of subjects are different due to their different cultural background.

    1996-11-29

    The U.S. Supreme Court has been urged by the Clinton Administration to overturn two appeals court rulings that bar States from enforcing laws that prohibit doctor-assisted suicide. Solicitor General Walter Dellinger asked the court to reverse rulings by the 2nd and 9th U.S. Circuit Court of Appeals blocking New York and Washington States from arresting doctors who hasten the death of patients. In both cases, the plaintiff included people with AIDS and their caregivers. President Clinton previously stated that he opposes euthanasia. AIDS policy advocates generally support legalizing assisted suicide and were disappointed in the administration's involvement in these cases.

    2016-03-04

    The aim of the present study is to investigate the potential anti-hepatocellular carcinoma (HCC) cell activity by 4SC-202, a novel class I HDAC inhibitor (HDACi). The associated signaling mechanisms were also analyzed. We showed that 4SC-202 treatment induced potent cytotoxic and proliferation–inhibitory activities against established HCC cell lines (HepG2, HepB3, SMMC-7721) and patient-derived primary HCC cells. Further, adding 4SC-202 in HCC cells activated mitochondrial apoptosis pathway, which was evidenced by mitochondrial permeability transition pore (mPTP) opening, cytochrome C cytosol release and caspase-3/-9 activation. Inhibition of this apoptosis pathway, by caspase-3/-9 inhibitors, mPTP blockers, or by shRNA-mediated knockdown of cyclophilin-D (Cyp-D, a key component of mPTP), significantly attenuated 4SC-202-induced HCC cell death and apoptosis. Reversely, over-expression of Cyp-D enhanced 4SC-202's sensitivity in HCC cells. Further studies showed that 4SC-202 induced apoptosis signal-regulating kinase 1 (ASK1) activation, causing it translocation to mitochondria and physical association with Cyp-D. This mitochondrial ASK1-Cyp-D complexation appeared required for mediating 4SC-202-induced apoptosis activation. ASK1 stable knockdown by targeted-shRNAs largely inhibited 4SC-202-induced mPTP opening, cytochrome C release, and following HCC cell apoptotic death. Together, we suggest that 4SC-202 activates ASK1-dependent mitochondrial apoptosis pathway to potently inhibit human HCC cells. - Highlights: • 4SC-202 exerts potent anti-proliferative and cytotoxic activity against established/primary HCC cells. • SC-202-induced anti-HCC cell activity relies on caspase-dependent apoptosis activation. • 4SC-202 activates Cyp-D-dependent mitochondrial apoptosis pathway in HCC cells. • 4SC-202 activates ASK1 in HCC cells, causing it translocation to mitochondria. • Mitochondrial ASK1-Cyp-D complexation mediates 4SC-202's activity in HCC cells.

  10. DPSK-3ASK transmission optimization by adapting modulation levels

    Science.gov (United States)

    Eiselt, Michael H.; Teipen, Brian T.

    2008-11-01

    For metro and regional 100-Gbps transmission, a transparent channel reach of 500-600 km is required and a 100-GHz channel grid is typically used. For these applications, a cost effective modulation format is introduced which can make use of electronic components designed for the already established 40-Gbps market, bypassing the requirements for novel electronic developments and therefore reducing the component cost. With this DPSK-3ASK modulation format, five information bits are transmitted in two consecutive symbols, leading to a symbol rate of 45 Gbaud, including overhead for framing and FEC. To minimize hardware requirements and to create a cost-effective solution, a single Mach-Zehnder modulator can be used to create the optical DPSK-3ASK signal after combining the phase and amplitude modulation signals into a 6-level modulator drive voltage. In this paper, it is demonstrated by numerical simulations that these voltage levels can be modified to adapt to varying signal distortions and thereby yield improved transmission performance. It is shown that by dynamically modifying the modulation levels based on the channel performance, dynamic signal impairments such as the non-linear effects from varying power levels, changes in chromatic dispersion, or varying PMD levels can be mitigated. Error-free performance (with FEC) can be obtained with 24 dB OSNR and 7ps DGD for a 112-Gbps (45-Gbaud) optical signal.

  11. Mindless processing of requests? Don't ask twice.

    Slugoski, B R

    1995-09-01

    This study examines the mindlessness hypothesis and its associated compliance-gaining paradigm from the perspective of politeness theory. The main prediction of politeness theory, which is not taken into account in the mindlessness literature, is that the perceived magnitude of an imposition is a function not only of the size of favour asked but also of the framing of the request itself. A confederate asked students studying in the library for either one or 10 sheets of paper using appropriate variations of Langer et al.'s three request types: no reason, placebic reason and real reason. Students then completed a questionnaire to determine: (a) how large the imposition on them had been; (b) their verbatim memories for the requests; and (c) self-reported compliance with the requests. In order to examine the effect of reflective thought on subjects' judgements and recall, this questionnaire was completed either immediately following compliance/non-compliance or three minutes later. The analyses established that the perceived imposition is influenced jointly by the actual imposition, the type of request and the time of judgement. Further, contrary to some previous research, the recall memory data provide support for a strong version of the mindlessness hypothesis, as well as new evidence for the reconstructive character of conversation memory. It is concluded that politeness theory describes a powerful heuristic that people use when processing requests.

    Kaempferol has been demonstrated to provide benefits for the treatment of atherosclerosis, coronary heart disease, hyperlipidemia, and diabetes through its antioxidant and anti-inflammatory properties. However, its role in cardiac hypertrophy remains to be elucidated. The aim of our study was to investigate the effects of kaempferol on cardiac hypertrophy and the underlying mechanism. Mice subjected to aorta banding were treated with or without kaempferol (100 mg/kg/d, p. o.) for 6 weeks. Echocardiography was performed to evaluate cardiac function. Mice hearts were collected for pathological observation and molecular mechanism investigation. H9c2 cardiomyocytes were stimulated with or without phenylephrine for in vitro study. Kaempferol significantly attenuated cardiac hypertrophy induced by aorta banding as evidenced by decreased cardiomyocyte areas and interstitial fibrosis, accompanied with improved cardiac functions and decreased apoptosis. The ASK1/MAPK signaling pathways (JNK1/2 and p38) were markedly activated in the aorta banding mouse heart but inhibited by kaempferol treatment. In in vitro experiments, kaempferol also inhibited the activity of ASK1/JNK1/2/p38 signaling pathway and the enlargement of H9c2 cardiomyocytes. Furthermore, our study revealed that kaempferol could protect the mouse heart and H9c2 cells from pathological oxidative stress. Our investigation indicated that treatment with kaempferol protects against cardiac hypertrophy, and its cardioprotection may be partially explained by the inhibition of the ASK1/MAPK signaling pathway and the regulation of oxidative stress.

  14. Klotho Regulates 14-3-3ζ Monomerization and Binding to the ASK1 Signaling Complex in Response to Oxidative Stress.

    Directory of Open Access Journals (Sweden)

    Reynolds K Brobey

    Full Text Available The reactive oxygen species (ROS-sensitive apoptosis signal-regulating kinase 1 (ASK1 signaling complex is a key regulator of p38 MAPK activity, a major modulator of stress-associated with aging disorders. We recently reported that the ratio of free ASK1 to the complex-bound ASK1 is significantly decreased in Klotho-responsive manner and that Klotho-deficient tissues have elevated levels of free ASK1 which coincides with increased oxidative stress. Here, we tested the hypothesis that: 1 covalent interactions exist among three identified proteins constituting the ASK1 signaling complex; 2 in normal unstressed cells the ASK1, 14-3-3ζ and thioredoxin (Trx proteins simultaneously engage in a tripartite complex formation; 3 Klotho's stabilizing effect on the complex relied solely on 14-3-3ζ expression and its apparent phosphorylation and dimerization changes. To verify the hypothesis, we performed 14-3-3ζ siRNA knock-down experiments in conjunction with cell-based assays to measure ASK1-client protein interactions in the presence and absence of Klotho, and with or without an oxidant such as rotenone. Our results show that Klotho activity induces posttranslational modifications in the complex targeting 14-3-3ζ monomer/dimer changes to effectively protect against ASK1 oxidation and dissociation. This is the first observation implicating all three proteins constituting the ASK1 signaling complex in close proximity.

    Pregestational diabetes significantly increases the risk of neural tube defects (NTDs). Maternal diabetes activates an Apoptosis Signal-regulating Kinase 1 (ASK1)-initiated pathway, which triggers neural stem cell apoptosis of the developing neuroepithelium leading to NTD formation. How high glucose of diabetes activates ASK1 is still unclear. In this study, we investigated the mechanism underlying high glucose-induced ASK1 activation. High glucose suppressed miR-17 expression, which led to an increase in its target gene Txnip (Thioredoxin-interacting protein). High glucose-increased Txnip enhanced its binding to the ASK1 inhibitor, thioredoxin (Trx), and thereby sequestered Trx from the Trx-ASK1 complex. High glucose-induced ASK1 activation and consequent apoptosis were abrogated by either the miR-17 mimic or Txnip siRNA knockdown. In contrast, the miR-17 inhibitor or Txnip ectopic overexpression mimicked the stimulative effect of high glucose on ASK1 and apoptosis. Thus, our study demonstrated that miR-17 repression mediates the pro-apoptotic effect of high glucose, and revealed a new mechanism underlying ASK1 activation, in which decreased miR-17 removes Trx inhibition on ASK1 through Txnip. © The Author 2015.

    Wallaert, Matthew; Ward, Andrew; Mann, Traci

    2014-07-01

    According to an oft-quoted piece of folk wisdom, if one wants something accomplished, the best person to ask is a busy person. We tested a version of this proposition in two studies. Study 1 exposed participants to a helping request in which cues promoting the relevant behavior were made more salient than those inhibiting it. Study 2 featured a request in which inhibiting cues were made more salient than cues promoting the behavior. In both studies, participants who were "busied" by high cognitive load showed more influence of the dominant behavioral pressure than did participants under minimal load. The results suggest that busy people can respond more to a helping appeal, but only when cues facilitating helping are more salient than those discouraging it.

    2011-01-01

    We consider the problem of human-assisted graph search: given a directed acyclic graph with some (unknown) target node(s), we consider the problem of finding the target node(s) by asking an omniscient human questions of the form "Is there a target node that is reachable from the current node?". This general problem has applications in many domains that can utilize human intelligence, including curation of hierarchies, debugging workflows, image segmentation and categorization, interactive search and filter synthesis. To our knowledge, this work provides the first formal algorithmic study of the optimization of human computation for this problem. We study various dimensions of the problem space, providing algorithms and complexity results. Our framework and algorithms can be used in the design of an optimizer for crowd-sourcing platforms such as Mechanical Turk.

    1996-06-14

    The state Supreme Court of Florida will rule on the legitimacy of a statute that restricts the ability of a plaintiff to sue for damages arising from HIV-contaminated blood transfusion. Under the malpractice law, patients have 4 years from the time of injury to file suit. In most HIV and AIDS cases, however, symptoms do not appear within the 4-year period. The Broward County Circuit Court recently dismissed a contaminated blood transfusion suit based on the expiration of the 4-year statute of repose. The Court of Appeals held the trial judge's application of the law correct, but found the statute uniquely unfair and harsh in HIV/AIDS cases. The State Supreme Court has been asked to rule on the issue.

  19. Three questions you need to ask about your brand.

    Keller, Kevin Lane; Sternthal, Brian; Tybout, Alice

    2002-09-01

    Traditionally, the people responsible for positioning brands have concentrated on the differences that set each brand apart from the competition. But emphasizing differences isn't enough to sustain a brand against competitors. Managers should also consider the frame of reference within which the brand works and the features the brand shares with other products. Asking three questions about your brand can help: HAVE WE ESTABLISHED A FRAME?: A frame of reference--for Coke, it might be as narrow as other colas or as broad as all thirst-quenching drinks--signals to consumers the goal they can expect to achieve by using a brand. Brand managers need to pay close attention to this issue, in some cases expanding their focus in order to preempt the competition. ARE WE LEVERAGING OUR POINTS OF PARITY?: Certain points of parity must be met if consumers are to perceive your product as a legitimate player within its frame of reference. For instance, consumers might not consider a bank truly a bank unless it offers checking and savings plans. ARE THE POINTS OF DIFFERENCE COMPELLING?: A distinguishing characteristic that consumers find both relevant and believable can become a strong, favorable, unique brand association, capable of distinguishing the brand from others in the same frame of reference. Frames of reference, points of parity, and points of difference are moving targets. Maytag isn't the only dependable brand of appliance, Tide isn't the only detergent with whitening power, and BMWs aren't the only cars on the road with superior handling. The key questions you need to ask about your brand may not change, but their context certainly will. The saviest brand positioners are also the most vigilant.

  20. The effects of survey mode and asking about future intentions on self-reports of colorectal cancer screening.

    2008-04-01

    Colorectal cancer (CRC) screening rates are often ascertained via self-reports but can be subject to overreporting bias. Asking about intention to get screened before asking about past screening may minimize overreporting of cancer screening. In a statewide survey conducted from July through October of 2005, we embedded an experiment that tested the effect of question ordering (asking about future intention to get screened before or after asking about past screening; "future first" and "future second," respectively), crossed with survey mode (mail versus telephone), on CRC screening rates. Weighted analysis focused on 752 respondents who were ages 50 years or older. We found (a) that asking about future intentions to get screened before asking about past screening (future first) statistically significantly lowers reports of past CRC screening [70.9% future second versus 58.0% future first; odds ratio (OR), 1.83; 95% confidence interval (95% CI), 1.08-3.13]; (b) that there was no main effect of survey mode; and (c) that the effect of the ordering of the future intentions item varies by survey mode. In the mailed survey, the odds of reporting past CRC screening were almost thrice greater in the future second condition compared with the future first condition (72.4% versus 49.0%, respectively; OR, 2.74; 95% CI, 1.22-6.17). In the telephone condition, the odds of reporting were only 28% higher in the future second (69.5%) condition than in the future first condition (63.9%; OR, 1.28; 95% CI, 0.64-2.57). The results suggest that asking about future intentions to get screened before the actual behavior elicits lower, and arguably more truthful reports of CRC screening but mainly in mailed surveys.

    2016-01-01

    Drawing appropriate diagrams is a useful problem solving heuristic that can transform a given problem into a representation that is easier to exploit for solving it. A major focus while helping introductory physics students learn problem solving is to help them appreciate that drawing diagrams facilitates problem solution. We conducted an investigation in which 111 students in an algebra-based introductory physics course were subjected to two different interventions during recitation quizzes throughout the semester. They were either (1) asked to solve problems in which the diagrams were drawn for them or (2) explicitly told to draw a diagram. A comparison group was not given any instruction regarding diagrams. We developed a rubric to score the problem-solving performance of students in different intervention groups. Here, we present some surprising results for problems which involve considerations of initial and final conditions.

    The objectives of this study were to determine: (1) how frequently pediatricians obtain a history of passive smoke exposure (PSE), (2) what type of advice regarding PSE they offer and how frequently they offer it, and (3) what methods and what assistance they believe would be useful to reduce PSE. A random sample of 1,000 US members (GEN) of the American Academy of Pediatrics (AAP) and all 724 members of the AAP sections of pulmonology, otolaryngology, and allergy (SPECS) were sent a questionnaire. Seven hundred fifty-five usable questionnaires were returned. Ninety-six percent of 321 general pediatricians obtained a PSE history at least "sometimes" but were much more likely to "always" do so when seeing a patient with asthma (87%) or recurrent otitis media (56%) than during well-child visits (41%) (p smoke around the child," or "quit smoking." Reasons for not initiating a cessation program included lack of skills (38%) or time (36%) or a belief that it was "not their responsibility" (13%). Pediatricians indicated that brochures for parents that describe the hazards of PSE and contain specific information regarding how to refer to community smoking cessation programs would be of most use to them in helping parents reduce PSE to their children. Pediatricians frequently ask about PSE and advise reducing it but seldom assist parents with specific advice regarding effective methods to quit smoking.

    Family medicine (FM) is an independent and distinct medical specialty in the developed countries such as USA, UK, Australia, and Canada since 1960s. FM teaching is imparted at undergraduate and postgraduate levels in countries such as Nepal, Pakistan, and Sri Lanka. Family practice is the practicing vocation of the majority doctors in India. The practitioners of FM include general practitioners, family physicians, FM specialists, and medical officers in the public sector. Medical students are largely unaware about FM career as this concept is not introduced at MBBS level. Faculty and senior doctors from other disciplines are also not able to answer the queries related to FM as they themselves also have gone through the same education system for last three decades, largely unexposed to the concept of academic family medicine. This article is a compilation of frequently asked questions, and their appropriate responses, presented here to dispel myths and misinformation about FM specialty. The answers are deliberated upon by Dr. Raman Kumar the founder president of the Academy of Family Physicians of India and the chief editor of the Journal of Family Medicine and Primary Care. This article was originally published as an interview in Docplexus, a popular online network and website for medical doctors in November 2015.

  9. Physics of Toys: The Joy of Asking Questions

    Science.gov (United States)

    Taylor, Beverley

    2014-03-01

    Children are natural scientists. They ask questions, they observe, they try things to see what happens. Often school-based science does little to nurture the young scientist and, in fact, may do just the opposite with thick textbooks, fact heavy lessons, and too many equations. The exploration of common toys produces deep learning by emphasizing concepts and connections before formal definitions and mathematics. It also connects the classroom to the familiar world outside of school and gets students writing and talking about physics ideas. At the university level, investigating what toys do and how they do it can be a challenging application of undergraduate physics from the introductory course up through senior mechanics. Toys provide an ideal system for the kind of open-ended inquiry that introduces students to what scientists really do. They can pose their own questions, explore the behavior of the system sufficiently to create a hypothesis, use their theoretical knowledge to make a simplified model of the system and predict an outcome, design an experiment, discover that the real world is messy, think about what they haven't taken into account with their simple model and try to improve it. I have spent close to 30 years thinking about how to use toys to enhance physics education from 4th grade through college. In the process I have collected hundreds of toys the majority of which relate to mechanics, but also to sound, light, electricity and magnetism. I will discuss the pedagogical reasons for using toys in physics education and the many different ways to use them from demonstrations to laboratory experiments to discussion starters as well as how it is possible to use the same toy with many different age levels by approaching the analysis differently. I will share a number of my favorite toys, but focus particularly on those related to energy concepts.

  10. Balancing task focus and relationship building: asking sleepy patients about traffic risk in treatment initiation consultations.

    Iversen, Clara; Broström, Anders; Ulander, Martin

    2017-04-24

    The use of traffic risk assessment questions is an understudied area in nursing research. Obstructive sleep apnoea is associated with an increased risk of traffic accidents. Therefore, traffic safety authorities demand adherent continuous positive airway pressure use. Nurses act as coaches to achieve treatment adherence, but they are also obliged to act as state agents by prohibiting obstructive sleep apnoea patients from drowsy driving. To examine how nurses and obstructive sleep apnoea patients manage traffic risk assessment questions in the relation-building context of treatment initiation consultations. To study, in detail, the actual practice of risk assessment, we used conversation analysis of 19 video-recorded initial treatment consultations with nurses and recently diagnosed obstructive sleep apnoea patients. The study received ethical approval from the Central Ethical Review Board in Linköping (registration number 214/231-32) and follows the ethical guidelines for qualitative research. Patients influence how nurses phrase questions about traffic risk by taking a stance to daytime sleepiness prior to the risk question. Nurses ask traffic risk questions in a way that assumes that driving is unproblematic if patients have not previously indicated problems. It may pose a significant problem when nurses, by accepting patients' prior stance when asking about traffic risk, orient to relationship building rather than task focus. To clarify the difference between their two potentially conflicting roles, nurses need to refer to existing laws and official guidelines when they raise the issue of risk in treatment initiation consultations. Nurses should also ask risk assessment questions in a problem-oriented communicative environment. Traffic risk assessment is sensitive yet important, as obstructive sleep apnoea is a highly prevalent problem causing excessive sleepiness. It is essential to acknowledge nurses' double roles with regard to coaching continuous positive

  12. Sexual orientation of trans adults is not linked to outcome of transition-related health care, but worth asking.

    Science.gov (United States)

    Since the beginning of contemporary transition-related care at the outset of the 20th century, sexual orientation has ben considered to be closely connected with gender identity and the developmental trajectories of trans people. Specifically, health professionals have regarded the anticipated post-transitional heterosexual behaviour of trans adults as predictive of a good outcome of cross-sex hormones and gender-confirming surgeries. This article reviews the current literature according to the question of whether the sexual orientation of trans people is linked to outcome measures following transition-related interventions. A comprehensive review was undertaken using the Medline database, searching for empirical studies published between 2010 and 2015. Out of a total of 474 studies, only 10 studies reported a follow-up of trans adults and assessed sexual orientation in the study protocol at all. Sexual orientation was predominantly assessed as homosexual versus non-homosexual related to sex assigned at birth. Only one 1 of 10 follow-up studies found a significant association according to the outcome between groups differentiated by sexual orientation. Empirically there is no link between sexual orientation and outcome of transition-related health care for trans adults. In order to provide comprehensive health care, we recommend asking for sexual behaviours, attractions and identities, as well as for gender experiences and expressions; however, this knowledge should not drive, but simply inform, such comprehensive care.

  13. The effects of measuring emotion: physiological reactions to emotional situations depend on whether someone is asking.

    Science.gov (United States)

    Kassam, Karim S; Mendes, Wendy Berry

    2013-01-01

    Measurement effects exist throughout the sciences-the act of measuring often changes the properties of the observed. We suggest emotion research is no exception. The awareness and conscious assessment required by self-report of emotion may significantly alter emotional processes. In this study, participants engaged in a difficult math task designed to induce anger or shame while their cardiovascular responses were measured. Half of the participants were asked to report on their emotional states and appraise their feelings throughout the experiment, whereas the other half completed a control questionnaire. Among those in the anger condition, participants assigned to report on their emotions exhibited qualitatively different physiological responses from those who did not report. For participants in the shame condition, there were no significant differences in physiology based on the self-report manipulation. The study demonstrates that the simple act of reporting on an emotional state may have a substantial impact on the body's reaction to an emotional situation.

    This was prepared for the business process improvement presentation to the Department of Energy. Los Alamos National Laboratory provides a single point of contact, the AskIT Service Desk, to address issues that impact customer productivity. At the most basic level, what customers want is for their calls to be received, to get a response from a knowledgeable analyst, and to have their issues resolved and their requests fulfilled. Providing a centralized, single point of contact service desk makes initiating technical or business support simple for the customer and improves the odds of immediately resolving the issue or correctly escalating the request to the next support level when necessary. Fulfilling customer requests through automated workflow also improves customer productivity and reduces costs. Finally, customers should be provided the option to solve their own problems through easy access to self-help resources such as frequently asked questions (FAQs) and how-to guides. To accomplish this, everyone who provides and supports services must understand how these processes and functions work together. Service providers and those who support services must “speak the same language” and share common objectives. The Associate Directorate for Business Innovation (ADBI) began the journey to improve services by selecting a known service delivery framework (Information Technology Infrastructure Library, or ITIL). From this framework, components that contribute significant business value were selected.

  16. Psoralen Inhibited Apoptosis of Osteoporotic Osteoblasts by Modulating IRE1-ASK1-JNK Pathway

    Osteoporosis is a common disease causing fracture in older populations. Abnormal apoptosis of osteoblasts contributes to the genesis of osteoporosis. Inhibiting apoptosis of osteoblasts provides a promising strategy to prevent osteoporosis. The proliferation of osteoblasts isolated from osteoporotic patients or healthy subjects was determined by MTT assay. Apoptosis was determined by Annexin V/PI assay. Protein expression was measured by western blot. The proliferation of osteoblasts isolated from osteoporotic patients was inhibited and the apoptosis level of these cells was higher than the osteoblasts from healthy subjects. Incubation with psoralen or estradiol significantly enhanced the proliferation and decreased the apoptosis level of osteoporotic osteoblasts. Western blot demonstrated that psoralen or estradiol treatment downregulated the expression of IRE1, p-ASK, p-JNK, and Bax. Meanwhile, expression of Bcl-2 was upregulated. Pretreatment by IRE1 agonist tunicamycin or JNK agonist anisomycin attenuated the effect of psoralen on osteoporotic osteoblasts. Psoralen inhibited apoptosis of osteoporotic osteoblasts by regulating IRE1-ASK1-JNK pathway.

    Ubiquitin-mediated protein degradation plays an essential role in plant growth and development as well as responses to environmental and endogenous signals. F-box protein is one of the key components of the SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complex, which recruit specific substrate proteins for subsequent ubiquitination and 26S proteasome-mediated degradation to regulate developmental processes and signaling networks. However, it is not easy to obtain purified F-box proteins with high activity due to their unstable protein structures. Here, we found that Arabidopsis SKP-like proteins (ASKs) can significantly improve soluble expression of F-box proteins and maintain their bioactivity. We established an efficient ASK-assisted method to express and purify plant F-box proteins. The method meets a broad range of criteria required for the biochemical analysis or protein crystallization of plant F-box proteins. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd.

  18. Adenosine 5′-monophosphate blocks acetaminophen toxicity by increasing ubiquitination-mediated ASK1 degradation

    Acetaminophen (APAP) overdose is the most frequent cause of drug-induced liver failure in the world. Hepatic c-jun NH2-terminal protein kinase (JNK) activation is thought to be a consequence of oxidative stress produced during APAP metabolism. Activation of JNK signals causes hepatocellular damage with necrotic and apoptotic cell death. Here we found that APAP caused a feedback increase in plasma adenosine 5′-monophsphate (5′-AMP). We demonstrated that co-administration of APAP and 5′-AMP significantly ameliorated APAP-induced hepatotoxicity in mice, without influences on APAP metabolism and its analgesic function. The mechanism of protection by 5′-AMP was through inhibiting APAP-induced activation of JNK, and attenuating downstream c-jun and c-fos gene expression. This was triggered by attenuating apoptosis signal-regulated kinase 1(ASK1) methylation and increasing ubiquitination-mediated ASK1 protein degradation. Our findings indicate that replacing the current APAP with a safe and functional APAP/5′-AMP formulation could prevent APAP-induced hepatotoxicity. PMID:28031524

  19. Does asking about suicide and related behaviours induce suicidal ideation? What is the evidence?

    2014-12-01

    There is a commonly held perception in psychology that enquiring about suicidality, either in research or clinical settings, can increase suicidal tendencies. While the potential vulnerability of participants involved in psychological research must be addressed, apprehensions about conducting studies of suicidality create a Catch-22 situation for researchers. Ethics committees require evidence that proposed studies will not cause distress or suicidal ideation, yet a lack of published research can mean allaying these fears is difficult. Concerns also exist in psychiatric settings where risk assessments are important for ensuring patient safety. But are these concerns based on evidence? We conducted a review of the published literature examining whether enquiring about suicide induces suicidal ideation in adults and adolescents, and general and at-risk populations. None found a statistically significant increase in suicidal ideation among participants asked about suicidal thoughts. Our findings suggest acknowledging and talking about suicide may in fact reduce, rather than increase suicidal ideation, and may lead to improvements in mental health in treatment-seeking populations. Recurring ethical concerns about asking about suicidality could be relaxed to encourage and improve research into suicidal ideation and related behaviours without negatively affecting the well-being of participants.

    To test the feasibility and assess the uptake and acceptability of implementing a consumer questions programme, AskShareKnow, to encourage consumers to use the questions '1. What are my options; 2. What are the possible benefits and harms of those options; 3. How likely are each of those benefits and harms to happen to me?' These three questions have previously shown important effects in improving the quality of information provided during consultations and in facilitating patient involvement. This single-arm intervention study invited participants attending a reproductive and sexual health-care clinic to view a 4-min video-clip in the waiting room. Participants completed three questionnaires: (T1) prior to viewing the intervention; (T2) immediately after their consultation; and (T3) two weeks later. A total of 121 (78%) participants viewed the video-clip before their consultation. Eighty-four (69%) participants asked one or more questions, and 35 (29%) participants asked all three questions. For those making a decision, 55 (87%) participants asked one or more questions, while 27 (43%) participants asked all three questions. Eighty-seven (72%) participants recommended the questions. After two weeks, 47 (49%) of the participants recalled the questions. Enabling patients to view a short video-clip before an appointment to improve information and involvement in health-care consultations is feasible and led to a high uptake of question asking in consultations. This AskShareKnow programme is a simple and feasible method of training patients to use a brief consumer-targeted intervention that has previously shown important effects in improving the quality of information provided during consultations and in facilitating patient involvement and use of evidence-based questions. ©2015 The Authors.

    Full Text Available BACKGROUND: Discrepant data have been published on the incidence and prognostic significance of ESR1 gene amplification in early breast cancer. PATIENTS AND METHODS: Formalin-fixed paraffin-embedded tumor blocks were collected from women with early breast cancer participating in two HeCOG adjuvant trials. Messenger RNA was studied by quantitative PCR, ER protein expression was centrally assessed using immunohistochemistry (IHC and ESR1 gene copy number by dual fluorescent in situ hybridization probes. RESULTS: In a total of 1010 women with resected node-positive early breast adenocarcinoma, the tumoral ESR1/CEP6 gene ratio was suggestive of deletion in 159 (15.7%, gene gain in 551 (54.6% and amplification in 42 cases (4.2%, with only 30 tumors (3% harboring five or more ESR1 copies.

    Pinon-juniper woodlands are an important vegetation type in the Great Basin. Old-growth and open shrub savanna woodlands have been present over much of the last several hundred years. Strong evidence indicates these woodlands have experienced significant tree infilling and major expansion in their distribution since the late 1800s by encroaching into surrounding landscapes once dominated by shrubs and herbaceous vegetation. Both infilling and expansion affects soil resources, plant community structure and composition, water and nutrient cycles, forage production, wildlife habitat, biodiversity, and fire patterns across the landscape. Another impact is the shift from historic fire regimes to larger and more intense wildfires that are increasingly determining the future of this landscape. This publication helps biologists and land managers consider how to look at expansion of woodlands and determine what questions to ask to develop a management strategy, including prescribed fire or other practices.

    The bone marrow plasma cell labeling index (PCLI) as measured by bromodeoxyuridine uptake is a well-established independent prognostic factor for patients with newly diagnosed multiple myeloma, but the test is not easily done in most laboratories. The purpose of this study was to determine if the proliferative activity (% S-phase) as determined by two-color flow cytometry for cytoplasmic immunoglobulin (cIg) light chain and DNA content also had prognostic significance. As part of Eastern Cooperative Oncology Group clinical trial E9486, 500 patients had successful performance of the bone marrow PCLI. Of 349 patients who had flow cIg and DNA content cytometry, 210 had adequate data to reliably calculate S-phase %. Patients with low % S-phase fraction (/=2%), median survivals 4.1 vs. 2.9 years (P = 0.032). Measurement of the S-phase % by flow cytometry gives significant prognostic information in patients with newly diagnosed myeloma. However, in multivariate analysis, S-phase % did not add prognostic information when PCLI was in the model. S-phase % added prognostic information only when all cases with flow measurement of S-phase % were included, and when PCLI was excluded from the model. Discriminating a population of only cIg positive cells proved difficult in patients with a low percentage of bone marrow plasma cells. Methodology to measure S-phase % in patients with a low percent plasma cells is needed before this technique can be used for diagnosis and prognosis in myeloma. Copyright 1999 Wiley-Liss, Inc.

    To evaluate the prognostic significance of the initial cerebro-spinal fluid (CSF) involvement of children with ALL enrolled from 1989 to 1996 in the EORTC 58881 trial. Patients (2025) were categorised according to initial central nervous system (CNS) status: CNS-1 (CNS negative, n=1866), CNS-2 (<5 leucocytes/mm(3), CSF with blasts, n=50), CNS-3 (CNS positive, n=49), TLP+ (TLP with blasts, n=60). CNS-directed therapy consisted in intravenous (i.v.) methotrexate (5 g/sqm) in 4-10 courses, and intrathecal methotrexate injections (10-20), according to CNS status. Cranial irradiation was omitted in all patients. In the CNS1, TLP+, CNS2 and CNS3 group the 8-year EFS rate (SE%) was 69.7% (1.1%), 68.8% (6.2%), 71.3% (6.5%) and 68.3% (6.2%), respectively. The 8-year incidence of isolated CNS relapse (SE%) was 3.4% (0.4%), 1.7% (1.7%), 6.1% (3.5%) and 9.4% (4.5%), respectively, whereas the 8-year isolated or combined CNS relapse incidence was 7.6% (0.6%), 3.5% (2.4%), 10.2% (4.4%) and 11.7% (5.0%), respectively. Patients with CSF blasts had a higher rate of initial bad risk features. Multivariate analysis indicated that presence of blasts in the CSF had no prognostic value: (i) for EFS and OS; (ii) for isolated and isolated or combined CNS relapse; WBC count<25 × 10(9)/L and Medac E-coli asparaginase treatment were each related to a lower CNS relapse risk. The presence of initial CNS involvement has no prognostic significance in EORTC 58881. Intensification of CNS-directed chemotherapy, without CNS radiation, is an effective treatment of initial meningeal leukaemic involvement. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Purpose: To determine whether patients with 1, 2, or 3 positive lymph nodes (LNs) have similar survival outcomes. Methods and Materials: We analyzed the Surveillance, Epidemiology, and End Results registry of breast cancer patients diagnosed between 1990 and 2003. We identified 10,415 women with T1-2N1M0 breast cancer who were treated with mastectomy with no adjuvant radiation, with at least 10 LNs examined and 6 months of follow-up. The Kaplan-Meier method and log–rank test were used for survival analysis. Multivariate analysis was performed using the Cox proportional hazard model. Results: Median follow-up was 92 months. Ten-year overall survival (OS) and cause-specific survival (CSS) were progressively worse with increasing number of positive LNs. Survival rates were 70%, 64%, and 60% (OS), and 82%, 76%, and 72% (CSS) for 1, 2, and 3 positive LNs, respectively. Pairwise log–rank test P values were <.001 (1 vs 2 positive LNs), <.001 (1 vs 3 positive LNs), and .002 (2 vs 3 positive LNs). Multivariate analysis showed that number of positive LNs was a significant predictor of OS and CSS. Hazard ratios increased with the number of positive LNs. In addition, age, primary tumor size, grade, estrogen receptor and progesterone receptor status, race, and year of diagnosis were significant prognostic factors. Conclusions: Our study suggests that patients with 1, 2, and 3 positive LNs have distinct survival outcomes, with increasing number of positive LNs associated with worse OS and CSS. The conventional grouping of 1-3 positive LNs needs to be reconsidered.

    Throughout its long history, the project of a science of grammar has always been an inherently philosophical one, in which the study of grammar was taken to have special epistemological significance. I ask why 20th and 21st century inquiry into Universal Grammar (UG) has largely lost this dimension, a fact that I argue is partially responsible for…

  12. Shoot first, ask questions later: Interpretative narratives of Neanderthal hunting

    Science.gov (United States)

    White, Mark; Pettitt, Paul; Schreve, Danielle

    2016-05-01

    This paper examines the hunting strategies employed by Neanderthals at a series of kill or near-kill sites from the Middle Palaeolithic of Europe (Mauran, La Borde, Taubach, Zwoleń and Salzgitter Lebenstedt). Using palaeolandscape reconstructions and animal ethology as our context, we adopt a multifaceted approach that views hunting as a chaîne opératoire involving the decisions and actions of both the hunter and the hunted, which together help reconstruct a forensic picture of past events as they unfolded. Our conclusions indicate that Neanderthals did not necessarily pre-select individuals from a herd, who they then isolated, pursued and killed, but rather ambushed whole groups, which they slaughtered indiscriminately. There is strong evidence, however, that Neanderthals were highly selective in the carcasses they then chose to process. Our conclusions suggest that Neanderthals were excellent tacticians, casual executioners and discerning diners.

    In the 1980's and 1990's, breakthroughs about Pluto and the outer solar system laid the groundwork for the Outer Planets Science Working Group (1992), the Pluto Kuiper Express mission Science Definition Team (1996), and the Announcement of Opportunity for the Pluto Kuiper-Belt mission in 2001. These included specific science goals that molded the mission design, instrument selection, and observing sequence. These goals held up amazingly well over the decades. This historical review of New Horizons will explain how ground-based and theoretical work prepared us for a successful investigation of Pluto, and speculate on some of the new questions raised by the New Horizons flyby of the Pluto system.This work was supported by NASA's New Horizons project.

    Background The prognostic value of histologic response for osteosarcoma may have changed with induction chemotherapy schedules over time. We hypothesized that the increased intensity of induction therapy provided on INT0133 compared to the Children’s Cancer Group study CCG-782 would diminish the impact of histologic response on the risk of events after definitive surgery. Methods Retrospective analysis was performed for patients aged osteosarcoma enrolled on CCG-782 and INT0133. Clinical factors were evaluated for association with response and outcome. Good response was defined as <5% viable tumor at resection. Associations of response, study, and post-definitive surgery event-free survival (EFS-DS)were determined using Cox proportional hazard models. EFS-DS was estimated by Kaplan–Meier methodology. Results Data were available for 814 patients (206 CCG-782, 608 INT0133). For good responders, 10-year EFS-DS (±SE) was 75.4% ± 7.7% for CCG-782 and 70.8% ± 3.1% for INT0133. For poor responders, 10-year EFS-DS was 39.9% ± 4.9% for CCG-782 and 58.4% ± 3.1% for INT0133. Histologic response predicted outcome across studies (P < 0.0001). Significant interaction between study and histologic response was observed for EFS-DS (P = 0.011). Using proportional hazards regression, INT0133 poor responders had less risk of events compared to CCG-782 poor responders (relative hazard ratio (RHR) = 0.6:1), but good responders on INT0133 had a greater risk of events compared to CCG-782 good responders (RHR = 1.53:1). Conclusion We observed an inverse relationship between the predictive value of tumor necrosis and intensity of induction therapy, raising questions about the true prognostic value of histologic response. This highlights the need for novel markers to develop strategies for treatment in future trials. PMID:27128693

    2016-03-01

    Full Text Available In this essay, the editors and contributors to this special section on SoTL in the Arts and Humanities argue that given the current climate and context, debates within SoTL about appropriate methodology both lead scholars from their disciplines to reject SoTL and also, more importantly, distract us from more significant questions and challenges. If, instead, SoTL would embrace not only its diversity but also its political potential, then we, as a scholarly community, would be in a position to do more than merely improve students’ learning in our own classrooms. We could help to transform higher education. To achieve that, we need a broader conversation and a wider range of studies. We also need to be mindful of and engaged with the political, economic, and ideological forces that are shaping our institutions, our work, and our students’ expectations.

  18. How much time has passed? Ask your heart

    2014-04-01

    Full Text Available Internal signals like one's heartbeats are centrally processed via specific pathways and both their neural representations as well as their conscious perception (interoception provide key information for many cognitive processes. Recent empirical findings propose that neural processes in the insular cortex, which are related to bodily signals, might constitute a neurophysiological mechanism for the encoding of duration. Nevertheless, the exact nature of such a proposed relationship remains unclear.We aimed to address this question by searching for the effects of cardiac rhythm on time perception by the use of a duration reproduction paradigm. Time intervals used were of 0.5, 2, 3, 7, 10, 14, 25 and 40 seconds length. In a framework of synchronization hypothesis, measures of phase locking between the cardiac cycle and start/stop signals of the reproduction task were calculated to quantify this relationship.The main result is that marginally significant synchronization indices between the heart cycle and the time reproduction responses for the time intervals of 2, 3, 10, 14 and 25 seconds length were obtained, while results were not significant for durations of 0.5, 7 and 40 seconds length. On the single participant level, several subjects exhibited some synchrony between the heart cycle and the time reproduction responses, most pronounced for the time interval of 25 seconds (8 out of 23 participants for 20% quantile. Better time reproduction accuracy was not related with larger degree of phase locking, but with greater vagal control of the heart. A higher interoceptive sensitivity was associated with a higher synchronization index for the 2s time interval only.We conclude that information obtained from the cardiac cycle is relevant for the encoding and reproduction of time in the time span of 2 to 25 seconds. Sympathovagal tone as well as interoceptive processes mediate the accuracy of time estimation.

    Apoptosis signal-regulating kinase-1 (ASK1) is the mitogen-activated protein kinase kinase kinase (MAPKKK) and participates in the various central nervous system (CNS) signaling pathways. In cerebral ischemia, vascular permeability in the brain is an important issue because regulation failure of it results in edema formation and blood-brain barrier (BBB) disruption. To determine the role of ASK1 on vascular permeability and edema formation following cerebral ischemia, we first investigated ASK1-related gene expression using microarray analyses of ischemic brain tissue. We then measured protein levels of ASK1 and vascular endothelial growth factor (VEGF) in brain endothelial cells after hypoxia injury. We also examined protein expression of ASK1 and VEGF, edema formation, and morphological alteration through cresyl violet staining in ischemic brain tissue using ASK1-small interference RNA (ASK1-siRNA). Finally, immunohistochemistry was performed to examine VEGF and aquaporin-1 (AQP-1) expression in ischemic brain injury. Based on our findings, we propose that ASK1 is a regulating factor of vascular permeability and edema formation in cerebral ischemia.

    Objective To study biomechanical performance of fracture-healing femoral head and neck after the hollow compressionb screws are taken out in ungrafting-bone group, grafting-bone group, normal group, and provide theoretical basis for the treatment of necrosis of the femoral head by bone grafting in the channel of screws. Methods Nine femurs fixed and preserved by formalin were used in this test. They were randomly divided into three groups: normal group, ungrafting-bone group, grafting-bone group. According to inversed-triangle, at the range of physiological load, it tested the defixed bias-value of three group femoral head at different load. The data were collected and analyzed. The three-dimension finite element model of the femoral head and neck was calculated. Nodal solution of stress value and max-offset was calculated at area of femoral head and neck, then the data were compared and analyzed.Results Compared with the mean of load-offset about the femoral head and neck, biomechanical capability of ungrafting-bone group was lowest with regard to other two groups , the influence was very hard, P <0.05. But there was no singnificant difference between normal group and graflng-bone group, P >0.05. Analysis of the three-dimension finite element model showed that the massive stress was concentrated at weight loading region of ungrafting-bone group's femoral head, it was an dangerous chance to lead to femoral head collapse. Conclusion For the treatment of femur neck fractures with cannulated compression screws, bone grafting in the channel of screw should be used to improve biomechanical integrity after fracture healed and cannulated compression screws are taken out. This is of benefit to loading in early stage and to preventing the collapse of femoral head, etc.%目的 探讨股骨颈骨折愈合后取出空心加压螺钉遗留钉道不植骨、植骨及正常的股骨头颈部的生物力学特性,为临床提供实验依据.方法 收集9付股骨标本测量

  16. The effects of measuring emotion: physiological reactions to emotional situations depend on whether someone is asking.

    Directory of Open Access Journals (Sweden)

    Karim S Kassam

    Full Text Available Measurement effects exist throughout the sciences-the act of measuring often changes the properties of the observed. We suggest emotion research is no exception. The awareness and conscious assessment required by self-report of emotion may significantly alter emotional processes. In this study, participants engaged in a difficult math task designed to induce anger or shame while their cardiovascular responses were measured. Half of the participants were asked to report on their emotional states and appraise their feelings throughout the experiment, whereas the other half completed a control questionnaire. Among those in the anger condition, participants assigned to report on their emotions exhibited qualitatively different physiological responses from those who did not report. For participants in the shame condition, there were no significant differences in physiology based on the self-report manipulation. The study demonstrates that the simple act of reporting on an emotional state may have a substantial impact on the body's reaction to an emotional situation.

    Clinical questions are often long and complex and take many forms. We have built a clinical question answering system named AskHERMES to perform robust semantic analysis on complex clinical questions and output question-focused extractive summaries as answers. This paper describes the system architecture and a preliminary evaluation of AskHERMES, which implements innovative approaches in question analysis, summarization, and answer presentation. Five types of resources were indexed in this system: MEDLINE abstracts, PubMed Central full-text articles, eMedicine documents, clinical guidelines and Wikipedia articles. We compared the AskHERMES system with Google (Google and Google Scholar) and UpToDate and asked physicians to score the three systems by ease of use, quality of answer, time spent, and overall performance. AskHERMES allows physicians to enter a question in a natural way with minimal query formulation and allows physicians to efficiently navigate among all the answer sentences to quickly meet their information needs. In contrast, physicians need to formulate queries to search for information in Google and UpToDate. The development of the AskHERMES system is still at an early stage, and the knowledge resource is limited compared with Google or UpToDate. Nevertheless, the evaluation results show that AskHERMES' performance is comparable to the other systems. In particular, when answering complex clinical questions, it demonstrates the potential to outperform both Google and UpToDate systems. AskHERMES, available at http://www.AskHERMES.org, has the potential to help physicians practice evidence-based medicine and improve the quality of patient care. Copyright © 2011 Elsevier Inc.

  1. How to Ask for a Favor: A Case Study on the Success of Altruistic Requests

    CERN Document Server

    Althoff, Tim; Jurafsky, Dan

    2014-01-01

    Requests are at the core of many social media systems such as question & answer sites and online philanthropy communities. While the success of such requests is critical to the success of the community, the factors that lead community members to satisfy a request are largely unknown. Success of a request depends on factors like who is asking, how they are asking, when are they asking, and most critically what is being requested, ranging from small favors to substantial monetary donations. We present a case study of altruistic requests in an online community where all requests ask for the very same contribution and do not offer anything tangible in return, allowing us to disentangle what is requested from textual and social factors. Drawing from social psychology literature, we extract high-level social features from text that operationalize social relations between recipient and donor and demonstrate that these extracted relations are predictive of success. More specifically, we find that clearly communic...

    Jasmonates are a new class of plant hormones that play important roles in plant development and plant defense. The COI1 gene was previously shown to be required for jasmonate- regulated plant fertility and defense. We demonstrated for the first time that COI1 interacts with the Arabidopsis SKP1-LIKE1 (ASK1) to form a complex that is required for jasmonate action in planta. Functional analysis by antisense strategy showed that ASK1 is involved in male fertility.

    The purpose of this study was to explore patient opinion about asking healthcare professionals to wash their hands prior to a clinical procedure and to explore if MRSA status and access to patient information about infection control would influence anxiety about asking. A descriptive survey was undertaken using a semi-structured questionnaire. The questionnaire was distributed to a randomised convenience sample of 185 in-patients across all departments of an acute NHS Trust hospital (response rate 59.4%). Spearman's rank order and Kendall Tau-b tests were used to analyse specific correlations. Respondents were more confident than anxious to be involved in a campaign that asked patients to ask staff to wash their hands. Patients were more anxious to ask if previous admission episodes were fewer, if their knowledge of MRSA was high and if there was less information about infection control available. Less anxiety was associated with patients who had MRSA in the past and the suggestion that staff wore badges saying 'It's OK to ask'.

  7. Information-seeking behaviors of medical students: a classification of questions asked of librarians and physicians.

    1994-07-01

    To solve a problem, a person often asks questions of someone with more expertise. This paper reports on a study of the types of questions asked and how the experts are chosen. In the study, sixty-three first-year medical students responded to clinical scenarios, each describing a patient affected by a toxin and asking questions concerning the identity of the toxin and its characteristics. After answering those questions, the students were asked to imagine that they had access to a medical reference librarian and an internist specializing in toxicology. The students then generated two questions for each expert about each clinical scenario. Each question was categorized according to the type of information requested, and the frequency of each type of question was calculated. The study found that students most often asked for the identification of the toxin(s), references about the scenario, or the effects of the toxin; an explanation of the patient's symptoms; or a description of the appropriate treatment. Students were more likely to address questions on the identity of the toxin and references to the hypothetical librarian; they were more likely to ask the internist for explanations of the symptoms and descriptions of the treatment. The implications of these results for the design of information and educational systems are discussed.

    The current meta-analysis estimated the magnitude of the impact of asking intention and self-prediction questions on rates of subsequent behavior, and examined mediators and moderators of this question–behavior effect (QBE). Random-effects meta-analysis on 116 published tests of the effect indicated that intention/prediction questions have a small positive effect on behavior (d+ = 0.24). Little support was observed for attitude accessibility, cognitive dissonance, behavioral simulation, or processing fluency explanations of the QBE. Multivariate analyses indicated significant effects of social desirability of behavior/behavior domain (larger effects for more desirable and less risky behaviors), difficulty of behavior (larger effects for easy-to-perform behaviors), and sample type (larger effects among student samples). Although this review controls for co-occurrence of moderators in multivariate analyses, future primary research should systematically vary moderators in fully factorial designs. Further primary research is also needed to unravel the mechanisms underlying different variants of the QBE. PMID:26162771

    Cardiac troponin (cTn) assays have quickly gained in analytical sensitivity to become what are termed 'high-sensitivity cardiac troponin' (hs-cTn) assays, bringing a flurry of dense yet incomplete literature data. The net result is that cTn assays are not yet standardized and there are still no consensus-built data on how to use and interpret cTn assay results. To address these issues, the authors take cues and clues from multiple disciplines to bring responses to frequently asked questions. In brief, the effective use of hs-cTn hinges on knowing: specific assay characteristics, particularly precision at the 99th percentile of a reference population; factors of variation at the 99th percentile value; and the high-individuality of hs-cTn assays, for which the notion of individual kinetics is more informative than straight reference to 'normal' values. The significance of patterns of change between two assay measurements has not yet been documented for every hs-cTn assay. Clinicians need to work hand-in-hand with medical biologists to better understand how to use hs-cTn assays in routine practice.

    Women in sub-Saharan Africa are vulnerable to acquiring HIV infection and reproductive tract infections. Bacterial vaginosis (BV), a disruption of the vaginal microbiota, has been shown to be strongly associated with HIV infection. Risk factors related to potentially protective or harmful microbiota species are not known. We present cross-sectional quantitative polymerase chain reaction data of the Lactobacillus genus, five Lactobacillus species, and three BV-related bacteria (Gardnerella vaginalis, Atopobium vaginae, and Prevotella bivia) together with Escherichia coli and Candida albicans in 426 African women across different groups at risk for HIV. We selected a reference group of adult HIV-negative women at average risk for HIV acquisition and compared species variations in subgroups of adolescents, HIV-negative pregnant women, women engaging in traditional vaginal practices, sex workers and a group of HIV-positive women on combination antiretroviral therapy. We explored the associations between presence and quantity of the bacteria with BV by Nugent score, in relation to several factors of known or theoretical importance. The presence of species across Kenyan, South African and Rwandan women was remarkably similar and few differences were seen between the two groups of reference women in Kenya and South Africa. The Rwandan sex workers and HIV-positive women had the highest G. vaginalis presence (p = 0.006). Pregnant women had a higher Lactobacillus genus mean log (7.01 genome equivalents (geq)/ml) compared to the reference women (6.08 geq/ml). L. vaginalis (43%) was second to L. iners (81.9%) highly present in women with a normal Nugent score. Recent sexual exposure negatively affected the presence of L. crispatus (e. L. crispatus and L. vaginalis in women with a normal Nugent score appeared lower compared to non-African studies. Furthermore, Lactobacillus species were negatively affected by sexual behavioural.

    "Truth" has been used as a baseline condition in several functional magnetic resonance imaging (fMRI) studies of deception. However, like deception, telling the truth is an inherently social construct, which requires consideration of another person's mental state, a phenomenon known as Theory of Mind. Using a novel ecological paradigm, we examined blood oxygenation level dependent (BOLD) responses during social and simple truth telling. Participants (n = 27) were randomly divided into two competing teams. Post-competition, each participant was scanned while evaluating performances from in-group and out-group members. Participants were asked to be honest and were told that their evaluations would be made public. We found increased BOLD responses in the medial prefrontal cortex, bilateral anterior insula and precuneus when participants were asked to tell social truths compared to simple truths about another person. At the behavioral level, participants were slower at responding to social compared to simple questions about another person. These findings suggest that telling the truth is a nuanced cognitive operation that is dependent on the degree of mentalizing. Importantly, we show that the cortical regions engaged by truth telling show a distinct pattern when the task requires social reasoning.

  13. Mixed Waste Working Group report

    Energy Technology Data Exchange (ETDEWEB)

    1993-11-09

    The treatment of mixed waste remains one of this country`s most vexing environmental problems. Mixed waste is the combination of radioactive waste and hazardous waste, as defined by the Resource Conservation and Recovery Act (RCRA). The Department of Energy (DOE), as the country`s largest mixed waste generator, responsible for 95 percent of the Nation`s mixed waste volume, is now required to address a strict set of milestones under the Federal Facility Compliance Act of 1992. DOE`s earlier failure to adequately address the storage and treatment issues associated with mixed waste has led to a significant backlog of temporarily stored waste, significant quantities of buried waste, limited permanent disposal options, and inadequate treatment solutions. Between May and November of 1993, the Mixed Waste Working Group brought together stakeholders from around the Nation. Scientists, citizens, entrepreneurs, and bureaucrats convened in a series of forums to chart a course for accelerated testing of innovative mixed waste technologies. For the first time, a wide range of stakeholders were asked to examine new technologies that, if given the chance to be tested and evaluated, offer the prospect for better, safer, cheaper, and faster solutions to the mixed waste problem. In a matter of months, the Working Group has managed to bridge a gap between science and perception, engineer and citizen, and has developed a shared program for testing new technologies.

    2017-10-04

    Social media (SoMe) is increasingly used in higher education (HE) to access knowledge and enable global communication. The SoMe platform Twitter(®) is particularly beneficial in these contexts because it is readily accessible, easily searchable (via hashtags) and global. Given these advantages, the twitter platform @AskAnatomist was created to foster a global weekly tweet chat, where students and academics from can ask and address anatomy-related questions. The aim of this study was to identify themes arising in the early stages of the @AskAnatomy Twitter community to gain insights into current needs/key areas for academic anatomists, students, and other followers. A qualitative analysis of tweets including the hashtag #AnatQ, (the associated @AskAnatomist hashtag), was undertaken to achieve this aim. Thematic analysis revealed three core themes arising in the formative stages of the @AskAnatomist Twitter site: (1) anatomical education modalities, (2) specific anatomy content, and (3) research motivations. These themes reveal controversies within the field of anatomical sciences, areas for potential education resource improvement and research, as well as the humor of anatomists. Though the original intent of the @AskAnatomist site was to engage the general public in anatomy content and knowledge, tweet analysis suggests that academic anatomists were the primary active "tweeters". Interestingly, this analysis reveals that the @AskAnatomist site progressed into a web-based community of practice (CoP), suggesting an additional benefit of SoMe communities in the field of anatomy. © 2017 American Association of Anatomists.

  15. Asking for a Commitment: Violations during the 2007 Match and the Effect on Applicant Rank Lists

    Directory of Open Access Journals (Sweden)

    Hern, Gene H.

    2015-02-01

    Full Text Available Introduction: Applicants to residency face a number of difficult questions during the interview process, one of which is when a program asks for a commitment to rank the program highly. The regulations governing the National Resident Matching Program (NRMP match explicitly forbid any residency programs asking for a commitment. Methods: We conducted a cross-sectional survey of applicants from U.S. medical schools to five specialties during the 2006-2007 interview season using the Electronic Residency Application Service of the Association of American Medical Colleges. Applicants were asked to recall being asked to provide any sort of commitment (verbal or otherwise to rank a program highly. Surveys were sent after rank lists were submitted, but before match day. We analyzed data using descriptive statistics and logistic regression. Results: There were 7,028 unique responses out of 11,983 surveys sent for a response rate of 58.6%. Of those who identified their specialty (emergency medicine, internal medicine, obstetrics and gynecology [OBGYN], general surgery and orthopedics, there were 6,303 unique responders. Overall 19.6% (1380/7028 of all respondents were asked to commit to a program. Orthopedics had the highest overall prevalence at 28.9% (372/474, followed by OBGYN (23.7%; 180/759, general surgery (21.7%; 190/876, internal medicine (18.3%; 601/3278, and finally, emergency medicine (15.4%; 141/916. Of those responding, 38.4% stated such questions made them less likely to rank the program. Conclusion: Applicants to residencies are being asked questions expressly forbidden by the NRMP. Among the five specialties surveyed, orthopedics and OBGYN had the highest incidence of this violation. Asking for a commitment makes applicants less likely to rank a program highly.

  16. Cardiac hypertrophy is associated with altered thioredoxin and ASK-1 signaling in a mouse model of menopause.

    Oxidative stress is implicated in menopause-associated hypertension and cardiovascular disease. The role of antioxidants in this process is unclear. We questioned whether the downregulation of thioredoxin (TRX) is associated with oxidative stress and the development of hypertension and target-organ damage (cardiac hypertrophy) in a menopause model. TRX is an endogenous antioxidant that also interacts with signaling molecules, such as apoptosis signal-regulated kinase 1 (ASK-1), independently of its antioxidant function. Aged female wild-type (WT) and follitropin receptor knockout (FORKO) mice (20-24 wk), with hormonal imbalances, were studied. Mice were infused with ANG II (400 ng x kg(-1) x min(-1); 14 days). Systolic blood pressure was increased by ANG II in WT (166+/-8 vs. 121+/-5 mmHg) and FORKO (176+/-7 vs. 115+/-5 mmHg; P<0.0001; n=9/group) mice. In ANG II-infused FORKO mice, cardiac mass was increased by 42% (P<0.001). This was associated with increased collagen content and augmented ERK1/2 phosphorylation (2-fold). Cardiac TRX expression and activity were decreased by ANG II in FORKO but not in WT (P<0.01) mice. ASK-1 expression, cleaved caspase III content, and Bax/Bcl-2 content were increased in ANG II-infused FORKO (P<0.05). ANG II had no effect on cardiac NAD(P)H oxidase activity or on O(2)(*-) levels in WT or FORKO. Cardiac ANG II type 1 receptor expression was similar in FORKO and WT. These findings indicate that in female FORKO, ANG II-induced cardiac hypertrophy and fibrosis are associated with the TRX downregulation and upregulation of ASK-1/caspase signaling. Our data suggest that in a model of menopause, protective actions of TRX may be blunted, which could contribute to cardiac remodeling independently of oxidative stress and hypertension.

    Physician-to-physician consultation and discussion have traditionally been conducted by telephone, paper, and "curbside" (face to face meetings). The implementation and use of physician-to-physician consultation via electronic mail in a military health care system has not been reported previously. The group mail function of the Composite Health Care System, the main outpatient medical automation system for the Department of Defense, was modified to create mailgroups for every specialty of the Walter Reed Army Medical Center to facilitate ease of physician-to-physician consultation. This modification was called the "Ask a Doc" system. The system was deployed to a 21-state health care network among triservice participants. There were 3,121 consultations logged from April 22, 1998, to December 31, 2000. Growth in use expanded initially and was sustained during a 3-year period. Average response time to consultations was less than 1 day (11.93 hours). Additional training and maintenance requirements were minimal. In general, the use of electronic consultation mirrored that of clinical practice. Most specialty consultations involved the disciplines of internal medicine. Use of the Ask a Doc system was representative of total clinical workload and increased access to specialty medical care over a wide geographic area. The distribution of use indicated that user statistics were legitimate, and quality improvement programs could easily troubleshoot the system. Ask a Doc was inserted into a regional health care network with minimal cost to support and implement and was sustained with very little effort for 3 years. Barriers to even wider use currently include lack of secure communications and the difficulty in assigning workload credit for electronic consultations.

    Quantifying the statistical features of the bid-ask spread offers the possibility of understanding some aspects of market liquidity. Using quote data for the 116 most frequently traded stocks on the New York Stock Exchange over the two-year period 1994-1995, we analyze the fluctuations of the average bid-ask spread S over a time interval deltat. We find that S is characterized by a distribution that decays as a power law P[S>x] approximately x(-zeta(S) ), with an exponent zeta(S) approximately = 3 for all 116 stocks analyzed. Our analysis of the autocorrelation function of S shows long-range power-law correlations, (S(t)S(t + tau)) approximately tau(-mu(s)), similar to those previously found for the volatility. We next examine the relationship between the bid-ask spread and the volume Q, and find that S approximately ln Q; we find that a similar logarithmic relationship holds between the transaction-level bid-ask spread and the trade size. We then study the relationship between S and other indicators of market liquidity such as the frequency of trades N and the frequency of quote updates U, and find S approximately ln N and S approximately ln U. Lastly, we show that the bid-ask spread and the volatility are also related logarithmically.

    2017-06-01

    Full Text Available A chipless RFID tag with unique ASK encoding technique is presented in this paper. The coding efficiency is enhanced regarding tag capacity. The amplitude varia¬tions of the backscattered RFID signal is used for encoding data instead of OOK. Strips of different widths are used to have amplitude variations. The ASK technique is applied using three different substrates of Kapton®HN, PET, and paper. To incorporate ASK technique, dual polarized rhombic shaped resonators are designed. These tags operate in the frequency range of 3.1–10.6 GHz with size of 70 × 42 mm^2. The presented tags are flexible and offer easy printability. The paper-based decomposable organic tag appears as an ultra low-cost solution for wide scale tracking. This feature enables them to secure a prominent position in the emerging fields of IoT and green electronics.

  20. ASK Florida; a climate change education professional development program for middle school teachers in Florida

    Weihs, R. R.

    2012-12-01

    A series of professional development workshops covering the fundamentals of climate change have been developed and facilitated for two groups of middle school science teachers in three Florida counties. The NASA-supported joint venture between Florida State University's Center for Ocean-Atmospheric Prediction Studies (COAPS) and the University of South Florida's (USF's) Coalition for Science Literacy, ASK Florida, focuses on expanding and deepening teachers' content knowledge of a wide range of climate change topics, connecting local and regional changes to the global picture, and supporting classroom implementation and effective teaching practices. Education experts from USF, climate scientists from COAPS, and Hillsborough county teachers and science coaches coordinated and developed the workshop content, which is based on Florida's Next Generation Sunshine State Standards in science, science curriculum guides for 6th grade, and teacher interest. Several scientists have facilitated activities during the workshop, including professors in meteorology and climatology, research scientists in the field, a NOAA program manager, the state climatologists for Florida, and others. Having these climate scientists present during the workshop provides teachers an opportunity to interact directly with the scientists and gain insight into the climatology field. Additionally, we host an open-forum discussion panel during which teachers can ask the experts about any topics of interest. Activities are designed to enhance the scientific skill level of the teachers. Introductory activities reinforce teachers' abilities to distinguish facts from opinions and to evaluate sources. Other activities provide hands-on experience using actual scientific data from NASA and other agencies. For example, teachers analyze precipitation data to create distributions of Florida rainfall, examine sea level trends at various locations, identify Atlantic hurricane frequencies during the phases of ENSO

  1. What becomes of infantile traumatic memories? An adult "wild child" is asked to remember.

    Terr, Lenore C

    2013-01-01

    A severely traumatized child, acting like a wild animal, was removed from her parents at thirteen months of age when her three-week-old sister was found, bitten and shaken to death. (Her father was later convicted of manslaughter and imprisoned.) The older child was also covered with bite marks. When she was twenty-nine months old, this child, whom I call "Cammie," was brought to me from miles away by herfoster parents for once-monthly psychotherapy. I have treated her, stressing abreaction, context, and correction, once a month ever since. When she was five years old Cammie's foster family adopted her. She is now twenty-two. I call her the "wild child" because of the growly voice, vomiting at will, grabbing at the genitalia of strangers, and cruelties to animals that she exhibited after her rescue. Presently she attends college and is training to be a preschool teacher or an aide to pediatricians. I have taken notes on what Cammie says and does during the twenty years she has come to me. In the spring of 2011, I was asked to speak later that year about infantile memories at the Margaret Mahler Symposium, Columbia University, New York. With the organizing committee's approval, I accompanied Cammie and her adoptive mother to the October 1, 2011, meeting and asked her in front of the psychoanalytic audience to recount her oldest remembrances. She, her mother, and I spoke about the nonverbal manifestations of her memory as well. I had briefly prepared Cammie and her mother for our presentation at the Mahler Symposium, but for the most part, it was spontaneous and unrehearsed. Their comments are quoted in this article. At twenty-two the "wild child" reports no verbal memory from her first year. On the other hand, her behaviors, attitudes, and perceptions over the years have reflected what occurred to her and indicate very active nonverbal memories of the traumatic experiences. Fragments of verbal memory that she recounted in therapy between ages two and three have

    2016-10-01

    When asking healthcare workers to wash their hands, perhaps a better message would be to ask them not to transmit diseases. This changes the emphasis from a single act of adherence to a concept of behavior change. Proper hand hygiene, proper use of personal protective equipment, and cough etiquette are the means to an end, to stop the transfer to organisms and disease, but not the ultimate goal itself. The ultimate goal is to stop the transmission of diseases and ultimately to decrease the occurrence of healthcare associated infections.

    This paper studies how the trade size and the historical sequence of trades affect bid-ask spreads, investors’ trading strategies, and the market maker’s learning process in a multi-period economy. First, we show that there is a nonzero cut-off size below which informed traders never buy or sell, and that larger trade sizes have positive bid-ask spreads, while smaller sizes do not. Then, we prove that the cut-off size decreases stochastically . We also derive the functional relationship betwe...

  5. Tips for a physician in getting the right job, part XII: general questions for the applicant to ask.

    The type and caliber of the questions asked by a job hunter is one of the ways an interviewer will evaluate the candidate. Questions that show poor preparation should not be asked, such as failure to read what the employer sent to the job seeker or not doing elementary research on the practice, the organization, or the community. Asking about insignificant details also is not helpful. Not having any good questions to ask is a negative in an interview. This article discusses many possible important questions for the applicant to ask during an interview.

    Aim: To investigate whether selenite, a known antioxidant, could decrease the activation of apoptosis signal regulating kinase 1/c-jun N-terminal kinase (ASK1/JNK) signaling cascade in cerebral ischemia/reperfusion (I/R) by activating the phosphatidylinositol 3-kinase (PI3K)/AKT pathway in rat hippocampi, and the neuroprotective effect of selenite against ischemic injury after 15 min of transient brain ischemia. Methods: Transient global brain ischemia was induced by 4-vessel occlusion into adult male Sprague-Dawley rats weighing 250-300 g. The rats were pretreated only with selenite (0.3 mg/kg dissolved in 0.9% saline) every 24 h for 7 d by means of intravenous injection of the tail or combined with LY294002 from d 5 by left cerebral ventricle'injection before surgery. Results: Selenite significantly increased AKT1 activation and decreased the activation of ASK1/JNK cascade via phosphorylating ASK1 at Ser-83 residue by AKT1 during early reperfusion after 15 min transient global brain ischemia. On the contrary, com-bined pretreatment of the rats with LY294002 (a specific PI3K inhibitor) and selen-ite significantly inhibited the effects solely with selenite. Conclusion: The activa-tion of the pro-apoptotic ASK1/JNK cascade, which is closely associated with oxidative stress, could be suppressed by selenite through activating the anti-apoptotic PI3K/AKT pathway during early reperfusion after cerebral ischemia in rat hippocampi.

    We report a novel function of peroxiredoxin-1 (Prx-1) in the ASK1-mediated signaling pathway. Prx-1 interacts with ASK1 via the thioredoxin-binding domain of ASK1 and this interaction is highly inducible by H2O2. However, catalytic mutants of Prx1, C52A, C173A, and C52A/C173A, could not undergo H2O2 inducible interactions, indicating that the redox-sensitive catalytic activity of Prx-1 is required for the interaction with ASK1. Prx-1 overexpression inhibited the activation of ASK1, and resulted in the inhibition of downstream signaling cascades such as the MKK3/6 and p38 pathway. In Prx-1 knockdown cells, ASK1, p38, and JNK were quickly activated, leading to apoptosis in response to H2O2. These findings suggest a negative role of Prx-1 in ASK1-induced apoptosis.

    2007-01-01

    Evidence-based practice (EBP) is increasingly being advocated as the preferred approach to practice in augmentative and alternative communication (AAC). The EBP process involves multiple steps. The asking of a well-built question is the first step in the quest for answers. At the same time it is also often the first stumbling block for practitioners. To facilitate the asking of well-built questions it may be helpful to follow a template. The most frequently used template is PICO, which stands for patient, intervention, comparison, and outcome [Richardson, W., Wilson, M., Nishikawa, J., & Hayward, R. (1995). The well-built clinical question: A key to evidence-based decisions. ACP Journal Club, 123, A12-A13]. In this article, we examine the suitability of the PICO template for AAC in terms of the representativeness of the components, and the appropriateness of its subcomponents, and their terminology. Based on this analysis, we propose the PESICO template, which stands for person, environments, stakeholders, intervention, comparison, and outcome. This template is then illustrated with examples representing a range of decision-making areas in AAC. Finally, directions for future research are provided. The reader will be able to: (1) appreciate the importance of asking well-built questions, (2) name the shortcomings of the PICO template, and (3) describe the components of the proposed PESICO template for asking well-built questions.

    The coherent ultra-dense wavelength division multiplexed passive optical network (UDWDM-PON) has been widely studied recently, in which the envelop detection based coherent reception of on-off keying (OOK) signal has been shown to possess both high receiver sensitivity and tolerance against laser linewidth/chirp. In order to increase the spectral efficiency (SE) to 2 bit/s/Hz, researchers formulated a hybrid DBPSK/ASK-2 modulation using the silicon Mach-Zehnder modulator (MZM), where both amplitude and phase modulation are employed. The experimental result shows that the proposed DBPSK/ASK-2 modulation is of better performance than PAM-4 at the same SE of 2 bit/s/Hz. When the low-cost silicon MZM and DFB laser of 4-MHz linewidth are employed, the receiver sensitivity of DBPSK/ASK-2 exceeds that of the PAM-4 by about 5.7 dB. This work can achieve about -46 dBm receiver sensitivity at 2.5 GBaud after transmission over 80-km standard single mode fiber (SSMF). The proposed DBPSK/ASK-2 modulation using low-cost silicon MZM and DFB laser is considered as a practical and reliable method for the future UDWDM-PON at the SE of 2 bit/s/Hz.

    Improve African American patient satisfaction and perceptions of physician cultural competency through the implementation of Ask Me 3 pamphlet which encourages patients to ask questions of physicians. Intervention participants received the pamphlet prior to their visit with the physician. Analysis evaluated differences in patient satisfaction and perceptions of physician cultural competency between intervention participants and controls. Intervention participants who saw their regular physician reported higher satisfaction. All found the questions to be helpful and reported knowing more about their medical condition or illness after the visit. The Ask Me 3 pamphlet is a low cost and logistically feasible tool that could be readily implemented in medical settings to facilitate physician-patient interaction. Improved satisfaction with the visit was found when the pamphlet was implemented during visits with a regular physician. Thus, our research findings suggest implementation of the Ask Me 3 pamphlet has the potential to improve health care behaviors and health outcomes and may ultimately lead to a reduction in health care disparities.

    Rashmi Ranjan Paital

    2016-01-01

    Full Text Available This paper empirically examines the relationship between stock return volatility, trading volume and bid-ask spread within the scope of mixture of distribution hypothesis (MDH and sequential information arrival hypothesis (SIAH in the Indian stock market using high frequency 5-minute data set over the period of 2 July 2012 to 31 December 2012. This is the first kind of study in India using bid-ask spread as an additional information variable along with trading volume to investigate the relationship with stock return volatility. Our empirical findings provide evidence of a positive contemporaneous relationship between return volatility and trading volume, and also between return volatility and bid-ask spread. Moreover, the results of Granger causality test show that the information content of trading volume and bid-ask spread are useful for predicting stock return volatility. Our results indicate that information arrival to investors tends to follow a sequential rather than a simultaneous process. This finding is consistent with the sequential information arrival hypothesis and contradicts the mixture of distribution hypothesis.

  20. Florida-focused climate change lesson demonstrations from the ASK Florida global and regional climate change professional development workshops

    A variety of Florida-focused climate change activities will be featured as part of the ASK Florida global and regional climate change professional development workshops. In a combined effort from Florida State University's Center for Ocean-Atmospheric Prediction Studies (COAPS) and University of South Florida's Coalition for Science Literacy (CSL), and supported by NASA's NICE initiative, the ASK Florida professional development workshops are a series of workshops designed to enhance and support climate change information and related pedagogical skills for middle school science teachers from Title-I schools in Florida. These workshops took place during a two-year period from 2011 to 2013 and consisted of two cohorts in Hillsborough and Volusia counties in Florida. Featured activities include lab-style exercises demonstrating topics such as storm surge and coastal geometry, sea level rise from thermal expansion, and the greenhouse effect. These types of labs are modified so that they allow more independent, inquiry thinking as they require teachers to design their own experiment in order to test a hypothesis. Lecture based activities are used to cover a broad range of topics including hurricanes, climate modeling, and sink holes. The more innovative activities are group activities that utilize roll-playing, technology and resources, and group discussion. For example, 'Climate Gallery Walk' is an activity that features group discussions on each of the climate literacy principles established by the United States Global Change Research Program. By observing discussions between individuals and groups, this activity helps the facilitators gather information on their previous knowledge and identify possible misconceptions that will be addressed within the workshops. Furthermore, 'Fact or Misconception' presents the challenge of identifying whether a given statement is fact or misconception based on the material covered throughout the workshops. It serves as a way to

    As "access brokers" to resources for their clients, homeless shelter workers are often in a position to aid victimized homeless women in securing medical and psychological services post-victimization. Given high rates of victimization within this population, we would expect that a routine part of a shelter's case management process would involve queries regarding victimization. Through in-depth qualitative interviews with 42 victimized homeless women in Chicago and Detroit, we sought to discover the extent to which such queries were pursued by staff at their current shelter. What we found is that women are seldom asked to provide a complete history that includes experiences of violent victimization and its effects. From these results, we make several recommendations aimed at improving homeless victims' access to services.

    Lesbian, gay, and bisexual service members can serve openly in the military with the repeal of the Don't Ask, Don't Tell policy. The fate of transgender service members remains uncertain as the policy preventing them from serving in the military remains under review. The health care needs of these populations remain for the most part unknown, with total acceptance and integration in the military yet to be achieved. In this paper, we review the literature on the health care needs of lesbian, gay, bisexual, and transgender (LGBT) service members, relying heavily on what is known about LGBT civilian and veteran populations. Significant research gaps about the health care needs of LGBT service members are identified, along with recommendations for closing those gaps. In addition, recommendations for improving LGBT acceptance and integration within the military are provided.

    2013-01-01

    We report on policy entrepreneurship by Servicemembers Legal Defense Network (SLDN) and how its legislative strategies used mini-windows of opportunity to shift Capitol Hill perspectives of Don't Ask, Don't Tell (DADT) from political plutonium to an emerging issue requiring a second look. Four phases in the legislative history of DADT are identified: radioactive, contested, emerging, and viable. In all, this article argues that SLDN's entrepreneurship focused on contesting congressional sensibilities to wait or defer on repeal, maintained that every discharge was damaging and transitioned toward a post-repeal mind set. Finally, we illustrate the importance of these transitions by comparing SLDN's 2004 estimated vote count for the introduction of the Military Readiness Enhancement Act with the final 2010 voting results on the Don't Ask, Don't Tell Repeal Act.

    2014-09-01

    A novel evolution scheme from legacy TDM-PON to the next generation WDM-PON with DPSK/ASK orthogonal modulation is proposed. The new WDM-PON is added into the existing PON infrastructure and coexisting with the current TDM-PON. To eliminate any change requirement for the existing TDM-PON, DPSK is applied for WDM-PON downstream. Meanwhile, upstream remodualtion is applied to achieve colorless ONU in WDM-PON. The application of DPSK/ASK reduces both crosstalk from coexisting and remodulation. The experiment results show the crosstalk is very little. Good performance is achieved for both unchanged coexisting TDM-PON and WDM-PON upstream signals in our proposed scheme.

  7. Targeting apoptosis signalling kinase-1 (ASK-1 does not prevent the development of neuropathy in streptozotocin-induced diabetic mice.

    Directory of Open Access Journals (Sweden)

    Victoria L Newton

    Full Text Available Apoptosis signal-regulating kinase-1 (ASK1 is a mitogen-activated protein 3 kinase (MAPKKK/MAP3K which lies upstream of the stress-activated MAPKs, JNK and p38. ASK1 may be activated by a variety of extracellular and intracellular stimuli. MAP kinase activation in the sensory nervous system as a result of diabetes has been shown in numerous preclinical and clinical studies. As a common upstream activator of both p38 and JNK, we hypothesised that activation of ASK1 contributes to nerve dysfunction in diabetic neuropathy. We therefore wanted to characterize the expression of ASK1 in sensory neurons, and determine whether the absence of functional ASK1 would protect against the development of neuropathy in a mouse model of experimental diabetes. ASK1 mRNA and protein is constitutively expressed by multiple populations of sensory neurons of the adult mouse lumbar DRG. Diabetes was induced in male C57BL/6 and transgenic ASK1 kinase-inactive (ASK1n mice using streptozotocin. Levels of ASK1 do not change in the DRG, spinal cord, or sciatic nerve following induction of diabetes. However, levels of ASK2 mRNA increase in the spinal cord at 4 weeks of diabetes, which could represent a future target for this field. Neither motor nerve conduction velocity deficits, nor thermal or mechanical hypoalgesia were prevented or ameliorated in diabetic ASK1n mice. These results suggest that activation of ASK1 is not responsible for the nerve deficits observed in this mouse model of diabetic neuropathy.

    Following Lawrence Harris (1989b) study of price clustering in stock prices, we examine the smae phenomenon in the forex market. The pattern of clustering in the final digit of bid/ask prices depends on the desired degree of price resolution. The selection of spreads also involves clustering, but this is driven by a different behavioural pattern, consistent with the pure attraction hypothesis. The combination of the two patterns can explain the differing frequencies of final digits in the bid...

    2016-12-01

    We examine the gender balance of the 18th and 19th meetings of the Cambridge Workshop on Cool Stellar Systems and the Sun (CS18 and CS19). The percent of female attendees at both meetings (31% at CS18 and 37% at CS19) was higher than the percent of women in the American Astronomical Society (25%) and the International Astronomical Union (18%). The representation of women in Cool Stars as SOC members, invited speakers, and contributed speakers was similar to or exceeded the percent of women attending the meetings. We requested that conference attendees assist in a project to collect data on the gender of astronomers asking questions after talks. Using this data, we found that men were over-represented (and women were under-represented) in the question sessions after each talk. Men asked 79% of the questions at CS18 and 75% of the questions at CS19, but were 69% and 63% of the attendees respectively. Contrary to findings from previous conferences, we did not find that the gender balance of questions was strongly affected by the session chair gender, the speaker gender, or the length of the question period. We also found that female and male speakers were asked a comparable number of questions after each talk. The contrast of these results from previous incarnations of the gender questions survey indicate that more data would be useful in understanding the factors that contribute to the gender balance of question askers. We include a preliminary set of recommendations based on this and other work on related topics, but also advocate for additional research on the demographics of conference participants. Additional data on the intersection of gender with race, seniority, sexual orientation, ability and other marginalized identities is necessary to fully address the role of gender in asking questions at conferences.

    Marrocco, Geraldine F

    2014-03-01

    Faculty who want to energize graduate students with creative classes that lead to long-lasting learning will benefit by designing course objectives, learning activities, and assessment tools using Fink's taxonomy of significant learning and Wiggins's insights on performance-based or educative assessments. Research shows that course designs relying on content-driven lectures and written examinations do not promote significant learning among adult learners. This article reviews six types of significant learning using Fink's taxonomy and examines Wiggins's "backward" approach to designing courses using performance-based assessments that gauge true learning and learning that promotes a lasting change. When designing courses, educators should ask: "What do I really want students to get out of this course?" The answers will direct the design of objectives, learning activities, and assessment tools. Designing graduate courses using Fink's taxonomy and Wiggins's backward approach can lead to significant learning to better prepare nurse practitioners for the future of health care.

    EL mice have been used as a model of epilepsy, whereas ASK mice are an epilepsy-resistant variant originating from a colony of EL mice. Mast cell-dependent anaphylaxis is easily inducible by stimulation with IgE and Ag in ASK mice, whereas EL mice are resistant to such stimuli. In this study we have characterized mast cells derived from these two strains. ASK mast cells proliferated more vigorously than EL cells in response to IL-3 and stem cell factor. Although ASK mast cells degranulated less vigorously than EL mast cells upon stimulation with IgE and Ag, ASK cells produced and secreted several-fold more TNF-alpha and IL-2 than EL cells. Consistent with the similarities of these ASK and EL mast cell responses with phenotypes of lyn(-/-) and wild-type mast cells, respectively, Lyn activity was reduced in ASK cells. In addition to the impaired Lyn activity, ASK cells just like lyn(-/-) cells exhibited reduced Syk activity, prolonged activation of ERK and JNK, and enhanced activation of Akt. Furthermore, the lipid raft-resident transmembrane adaptor protein Cbp/PAG that associates with Lyn was hypophosphorylated in ASK cells. Importantly, similar to lyn(-/-) cells, Fyn was hyperactivated in ASK cells. Therefore, these results are consistent with the notion that Lyn-dependent phosphorylation of Cbp/PAG negatively regulates Src family kinases. This study also suggests that reduced activity of Lyn, a negative regulator of mast cell activation, underlies the susceptibility of ASK mice to anaphylaxis and implies that dysregulation of Lyn and other Src family kinases contributes to epileptogenesis.

    Background Implementation of complex fetoscopic procedures that included intracorporeal suturing has been limited due to technical difficulties that might be surmounted with adequate training. Evaluating the impact of laparoscopic or fetoscopic training on fetoscopic performance was the aim of this study. Methods To evaluate fetoscopic performance after either laparoscopic or fetoscopic training, subjects were asked to perform four surgeon's square knots fetoscopically prior and post 2 hours of hands-on training. All subjects were medical students and novice in laparoscopic and fetoscopic interventions. Total time, knot stability (evaluated via tensiometer), suture accuracy, knot quality, and fetoscopic performance were assessed. Results Forty-six subjects were included in the study; after simple randomization, 24 were trained fetoscopically and 22 laparoscopically. Both groups had comparable baseline characteristics and improved after training significantly regarding all aspects assessed in this study. Subjects who trained fetoscopically were superior in terms of suturing and knot-tying performance. Conclusion Training significantly improves fetoscopic performance and may indeed be the keystone for future complex fetoscopic interventions. It seems advisable to train rather fetoscopically than laparoscopically resulting in higher suture and knot-tying quality. Georg Thieme Verlag KG Stuttgart · New York.

  3. How do I ask about your disability? An examination of interpersonal communication processes between medical students and patients with disabilities.

    2010-04-01

    Medical student behaviors were examined through digital recordings of interpersonal skills communication training framed around a brief curriculum on disability within a family medicine clerkship. This analysis focuses on interpersonal communication processes and ways medical students ask standardized patient educators about visually apparent disability (N = 142). Primary themes of asking about or avoiding disability were identified with regard to language and nonverbal communication in how medical students asked and whether they integrated chronic disability with new musculoskeletal pain complaints. Secondary themes related to timing and communication further contextualized the primary themes. Seventy-four percent of students asked about the disability. Analysis of feedback sessions immediately following the interactions revealed that more than half the students who did not ask about disability spontaneously recognized that they avoided disability language. Results suggest that some ways of asking about disability may inhibit patient disclosure and restrict relationship building. In particular, asking about disability, but then avoiding integrating disability disclosure into the treatment plan, or responding to disability-related disclosure with overly positive, infantilizing-type communication, may pose more difficult dilemmas than never asking about the disability. On the contrary, students who ignored disability altogether often also recognized they missed disability cues, thus providing a learning experience of considerable value. Underlying student attitudes and possibilities for integrating biomedical concerns with social-psychological impacts of disability are addressed.

    How big is your project world? Is it big enough to contain other cultures, headquarters, hierarchies, and weird harpoon-like guns? Sure it is. The great American poet Walt Whitman said it best, 'I am large/I contain multitudes.' And so must you, Mr. and Ms. Project Manager. In this issue of ASK, we look outside the project box. See how several talented project managers have expanded their definition of project scope to include managing environments outside the systems and subsystems under their care. Here's a sampling of what we've put together for you this issue: In 'Three Screws Missing,' Mike Skidmore tells about his adventures at the Plesetek Cosmodrome in northern Russia. Ray Morgan in his story, 'Our Man in Kauai,' suggests we take a broader view of what's meant by 'the team.' Jenny Baer-Riedhart, the NASA program manager on the same Pathfinder solar-powered airplane, schools us in how to sell a program to Headquarters in 'Know Thyself--But Don't Forget to Learn About the Customer Too.' Scott Cameron of Proctor and Gamble talks about sharpening your hierarchical IQ in 'The Project Manager and the Hour Glass.' Mike Jansen in 'The Lawn Dart' describes how he and the 'voodoo crew' on the Space Shuttle Advanced Solid Rocket Motor program borrowed a harpoon-like gun from the Coast Guard to catch particles inside of a plume. These are just some of the stories you'll find in ASK this issue. We hope they cause you to stop and reflect on your own project's relationship to the world outside. We are also launching a new section this issue, 'There are No Mistakes, Only Lessons.' No stranger to ASK readers, Terry Little inaugurates this new section with his article 'The Don Quixote Complex.'

    Graves' disease is the most common cause of hyperthyroidism in iodine-replete areas. Although progress has been made in our understanding of the pathogenesis of the disease, no treatment targeting pathogenic mechanisms of the disease is presently available. Therapies for Graves' hyperthyroidism are largely imperfect because they are bound to either a high rate of relapsing hyperthyroidism (antithyroid drugs) or lifelong hypothyroidism (radioiodine treatment or thyroidectomy). Aim of the present article is to offer a practical guidance to the reader by providing evidence-based answers to frequently asked questions in clinical practice.

    Full Text Available Global crisis gives quite big impact to the Indonesian Stock Exchange and also changes the investor behavior as well. Fundamental exchange which is considered fragile becomes instability threat and reflects uncertain condition. This research aims to analyze and explain empirically the impact of variance return, trading volume, stock prices and return shares toward bid-ask spread which is the measurement of asymmetrical information cost, also the impact of variance return, market value, bid-ask spread and dividend pay out towards common shares holding periods in Indonesia Stock Exchange and some dominant variable that affect them.The findings of this research strengthen the presumption that in conducting the investment, investors in Indonesian Stock Exchange is more oriented to short term investment by expecting more on common shares than dividend. Most investors keep their ownership in common shares in Indonesian Stock Exchange for two years. Besides, the efficient investment strategy which optimizes profit is “switching strategy”, following the market movement every time exactly, using technical information to active shares by moving from the shares that the price is predicted to decline to the increased ones. Moreover, the researcher also got the evidence that the investors in Indonesian capital market conduct their investment irrationally, investor’s analysis is getting technical and gives less attention to the fundamental factors. The decision of selling and buying which is conducted by the investors on common shares is based on the trading activity, that is actually a measurement of the scale of asymmetry information.

    The present study examined students' understanding and perceived effectiveness of a recent Australian alcohol campaign designed to increase students' awareness of excessive and harmful drinking. Six hundred and seventy one university students (51% females), who had seen the campaign posters, with the tagline "Is Getting Pissed Getting Pathetic? (Just Ask You Friends)", were asked to comment on the messages that the campaign was communicating and how informative, relevant, and effective they perceived the campaign. Many students were positive in their evaluations and described the messages as "truth and realistic", "clear and to the point", and that the campaign made them think about their own drinking. However, other views were more negative and indicative of psychological reactance. These included concerns that students "won't listen" or "don't care" about media campaigns, and that "they don't what to be told what to do". The findings highlight how media campaigns can help an audience contemplate behavioral change, however, they can also alienate students and promote counterproductive attitudes.

  17. Ask the right question: a critical step for practicing evidence-based laboratory medicine.

    Science.gov (United States)

    Price, Christopher P; Christenson, Robert H

    2013-07-01

    The purpose of laboratory medicine is to facilitate better decision making in clinical practice and healthcare delivery. Decision making implies an unresolved issue, problem or unmet need. The most important criterion for any investigation to be of value in clinical practice is that it addresses an unmet need. The different ways in which laboratory investigations are utilized in patient care can be represented in the form of questions. It is important that these questions are articulated to highlight the variables that will impact on the effectiveness of the investigation in the scenario being considered. These variables include the characteristics of the patient (or population) and clinical setting, the nature of the decision and action taken on receipt of the test result and the expected outcome. Asking a question is the first step of the evidence-based laboratory medicine (EBLM) cycle, the other steps being acquiring the evidence, critically appraising the evidence, applying the evidence and auditing use of the evidence. Getting the question right determines the quality of the whole process, thus, defines the quality in practice of laboratory medicine. Whilst the main focus of the EBLM cycle is to provide a strong evidence base for use in clinical practice, it is clear that the five steps are equally applicable in commissioning, delivery and audit (performance management) of services. Asking the right question is crucial to improving the quality of evidence, and practice, in laboratory medicine, and should be used in routine laboratory medicine practice and management throughout healthcare.

  18. Don't Ask a Neuroscientist about Phases of the Moon.

    Shats, Katherine; Brindley, Timothy; Giordano, James

    2016-10-01

    Ongoing developments in neuroscientific techniques and technologies-such as neuroimaging-offer potential for greater insight into human behavior and have fostered temptation to use these approaches in legal contexts. Neuroscientists are increasingly called on to provide expert testimony, interpret brain images, and thereby inform judges and juries who are tasked with determining the guilt or innocence of an individual. In this essay, we draw attention to the actual capabilities and limitations of currently available assessment neurotechnologies and examine whether neuroscientific evidence presents unique challenges to existing frameworks of evidence law. In particular, we focus on (1) fundamental questions of relevance and admissibility that can and should be posed before the tests afforded in Daubert v. Merrill Dow Pharmaceuticals or Frye v. U.S. are applied and (2) how these considerations fit into the broader contexts of criminal law. We contend that neuroscientific evidence must first be scrutinized more heavily for its relevance, within Daubert and Federal Rule of Evidence 702, to ensure that the right questions are asked of neuroscientists, so as to enable expert interpretation of neuroscientific evidence within the limits of their knowledge and discipline that allows the judge or jury to determine the facts at issue in the case. We use the analogy provided by the Daubert court of an expert on the phases of the moon testifying to an individual's behavior on a particular night to ensure that we are, in fact, asking the neuroscientific expert the appropriate question.

    Even though the expanded programme for immunization (EPI) coverage at national level is high in Burkina (95% of fully vaccinated children), mothers of children following EPI in Health Centres (HC) would benefit from being reminded of EPI sessions by sending SMS (short message service) to their own mobile phone, or through mobile phone of a family member living in the same compound. SMS could be sent through Computerized Immunization Registers (CIR), hosted by HC computers. 210 mothers of children aged 0 to 5 years were chosen at random and questioned if they owned a mobile phone, if they could read a SMS, or, if not, what language they would understand if a voice SMS was sent. They were also asked if a family member could receive, read and transmit the message, if mothers did not own a mobile phone. They were also asked if they are willing to give their telephone number to HC. 94% of mothers could be reached through written or voice SMS, sent to their own or family member's mobile phone. 100% of mothers would be willing to give their telephone number to their HC to improve their ability to come at the right time for vaccination sessions. SMS reminders, delivered through CIR, should improve EPI attendance and management of sessions in HC, especially in epidemic context.

    This project is currently under contract for research through the Department of Homeland Security until 2011. The group I was responsible for studying has to remain confidential so as not to affect the current project. All dates, reference links and authors, and other distinguishing characteristics of the original group have been removed from this report. All references to the name of this group or the individual splinter groups has been changed to 'Group X'. I have been collecting texts from a variety of sources intended for the use of recruiting and radicalizing members for Group X splinter groups for the purpose of researching the motivation and intent of leaders of those groups and their influence over the likelihood of group radicalization. This work included visiting many Group X websites to find information on splinter group leaders and finding their statements to new and old members. This proved difficult because the splinter groups of Group X are united in beliefs, but differ in public opinion. They are eager to tear each other down, prove their superiority, and yet remain anonymous. After a few weeks of intense searching, a list of eight recruiting texts and eight radicalizing texts from a variety of Group X leaders were compiled.

  1. Glycoproteins: Occurrence and Significance

    Science.gov (United States)

    Wittmann, Valentin

    Protein glycosylation is regarded as the most complex form of post-translational modification leading to a heterogeneous expression of glycoproteins as mixtures of glycoforms. This chapter describes the structure and occurrence of glycoproteins with respect to their glycan chains. Discussed are different carbohydrate-peptide linkages including GPI anchors, common structures of N- and O-glycans, and the structure of glycosaminoglycans contained in proteoglycans. Also covered are the bacterial cell wall polymer peptidoglycan and the glycopeptide antibiotics of the vancomycin group. Properties and functions of the glycans contained in glycoproteins are dealt with in the next chapter of this book.

  2. The ASK1 gene regulates B function gene expression in cooperation with UFO and LEAFY in Arabidopsis.

    Zhao, D; Yu, Q; Chen, M; Ma, H

    2001-07-01

    The Arabidopsis floral regulatory genes APETALA3 (AP3) and PISTILLATA (PI) are required for the B function according to the ABC model for floral organ identity. AP3 and PI expression are positively regulated by the LEAFY (LFY) and UNUSUAL FLORAL ORGANS (UFO) genes. UFO encodes an F-box protein, and we have shown previously that UFO genetically interacts with the ASK1 gene encoding a SKP1 homologue; both the F-box containing protein and SKP1 are subunits of ubiquitin ligases. We show here that the ask1-1 mutation can enhance the floral phenotypes of weak lfy and ap3 mutants; therefore, like UFO, ASK1 also interacts with LFY and AP3 genetically. Furthermore, our results from RNA in situ hybridizations indicate that ASK1 regulates early AP3 and PI expression. These results support the idea that UFO and ASK1 together positively regulate AP3 and PI expression. We propose that the UFO and ASK1 proteins are components of a ubiquitin ligase that mediates the proteolysis of a repressor of AP3 and PI expression. Our genetic studies also indicate that ASK1 and UFO play a role in regulating the number of floral organ primordia, and we discuss possible mechanisms for such a regulation.

  4. When are emotions related to group-based appraisals? A comparison between group-based emotions and general group emotions.

    Science.gov (United States)

    Kuppens, Toon; Yzerbyt, Vincent Y

    2014-12-01

    In the literature on emotions in intergroup relations, it is not always clear how exactly emotions are group-related. Here, we distinguish between emotions that involve appraisals of immediate group concerns (i.e., group-based emotions) and emotions that do not. Recently, general group emotions, measured by asking people how they feel "as a group member" but without specifying an object for these emotions, have been conceptualized as reflecting appraisals of group concerns. In contrast, we propose that general group emotions are best seen as emotions about belonging to a group. In two studies, general group emotions were closely related to emotions that are explicitly measured as belonging emotions. Two further studies showed that general group emotions were not related to appraisals of immediate group concerns, whereas group-based emotions were. We argue for more specificity regarding the group-level aspects of emotion that are tapped by emotion measures.

  5. Asking for help online: Lesbian, gay, bisexual and trans youth, self-harm and articulating the 'failed' self.

    Science.gov (United States)

    McDermott, Elizabeth

    2015-11-01

    International evidence suggests that young people are less likely to seek help for mental health problems in comparison with adults. This study focused on lesbian, gay, bisexual and trans young people who are a population group with an elevated risk of suicide and self-harm, and little is known about their help-seeking behaviour. Utilising qualitative virtual methods, lesbian, gay, bisexual and trans youth web-based discussions about seeking help for suicidal feelings and self-harming were investigated. Findings from a thematic analysis indicate that these young people wanted assistance but found it difficult to (1) ask for help, (2) articulate emotional distress and (3) 'tell' their selves as 'failed'. This analysis suggests that key to understanding these problems are emotions such as shame which arise from negotiating norms connected to heterosexuality, adolescence and rationality. I argue that these norms act to regulate what emotions it is possible to feel, what emotions it is possible to articulate and what type of young lives that can be told. The future development of health and social care interventions which aim to reduce lesbian, gay, bisexual and trans youth suicide and self-harm need to work with a nuanced understanding of the emotional life of young people if they are to be effective.

  6. A metro-access integrated network with all-optical virtual private network function using DPSK/ASK modulation format

    Tian, Yue; Leng, Lufeng; Su, Yikai

    2008-11-01

    All-optical virtual private network (VPN), which offers dedicated optical channels to connect users within a VPN group, is considered a promising approach to efficient internetworking with low latency and enhanced security implemented in the physical layer. On the other hand, time-division multiplexed (TDM) / wavelength-division multiplexed (WDM) network architecture based on a feeder-ring with access-tree topology, is considered a pragmatic migration scenario from current TDM-PONs to future WDM-PONs and a potential convergence scheme for access and metropolitan networks, due to its efficiently shared hardware and bandwidth resources. All-optical VPN internetworking in such a metro-access integrated structure is expected to cover a wider service area and therefore is highly desirable. In this paper, we present a TDM/WDM metro-access integrated network supporting all-optical VPN internetworking among ONUs in different sub- PONs based on orthogonal differential-phase-shift keying (DPSK) / amplitude-shift keying (ASK) modulation format. In each ONU, no laser but a single Mach-Zehnder modulator (MZM) is needed for the upstream and VPN signal generation, which is cost-effective. Experiments and simulations are performed to verify its feasibility as a potential solution to the future access service.

    Tsunamis have inflicted death and destruction on the coastlines of the world throughout history. The occurrence of tsunamis and the resulting effects have been collected and studied as far back as the second millennium B.C. The knowledge gained from cataloging and examining these events has led to significant changes in our understanding of tsunamis, tsunami sources, and methods to mitigate the effects of tsunamis. The most significant, not surprisingly, are often the most devastating, such as the 2011 Tohoku, Japan earthquake and tsunami. The goal of this poster is to give a brief overview of the occurrence of tsunamis and then focus specifically on several significant tsunamis. There are various criteria to determine the most significant tsunamis: the number of deaths, amount of damage, maximum runup height, had a major impact on tsunami science or policy, etc. As a result, descriptions will include some of the most costly (2011 Tohoku, Japan), the most deadly (2004 Sumatra, 1883 Krakatau), and the highest runup ever observed (1958 Lituya Bay, Alaska). The discovery of the Cascadia subduction zone as the source of the 1700 Japanese "Orphan" tsunami and a future tsunami threat to the U.S. northwest coast, contributed to the decision to form the U.S. National Tsunami Hazard Mitigation Program. The great Lisbon earthquake of 1755 marked the beginning of the modern era of seismology. Knowledge gained from the 1964 Alaska earthquake and tsunami helped confirm the theory of plate tectonics. The 1946 Alaska, 1952 Kuril Islands, 1960 Chile, 1964 Alaska, and the 2004 Banda Aceh, tsunamis all resulted in warning centers or systems being established.The data descriptions on this poster were extracted from NOAA's National Geophysical Data Center (NGDC) global historical tsunami database. Additional information about these tsunamis, as well as water level data can be found by accessing the NGDC website www.ngdc.noaa.gov/hazard/

    The female athlete triad of disordered eating, amenorrhea, and osteoporosis affects many active women and girls, especially those in sports that emphasize appearance or leanness. Because of the athlete's psychological defense mechanisms and the stigma surrounding disordered eating, physicians may need to ask targeted questions about nutrition habits when assessing a patient who has a stress fracture or amenorrhea, or during preparticipation exams. Carefully worded questions can help. Physical signs and symptoms include unexplained recurrent or stress fracture, dry hair, low body temperature, lanugo, and fatigue. Targeted lab tests to assess nutritional and hormonal status are essential in making a diagnosis that will steer treatment, as are optimal radiologic tests like dual-energy x-ray absorptiometry for assessing bone density.

  11. Toward Question-Asking Machines: The Logic of Questions and the Inquiry Calculus

    2005-01-01

    For over a century, the study of logic has focused on the algebra of logical statements. This work, first performed by George Boole, has led to the development of modern computers, and was shown by Richard T. Cox to be the foundation of Bayesian inference. Meanwhile the logic of questions has been much neglected. For our computing machines to be truly intelligent, they need to be able to ask relevant questions. In this paper I will show how the Boolean lattice of logical statements gives rise to the free distributive lattice of questions thus defining their algebra. Furthermore, there exists a quantity analogous to probability, called relevance, which quantifies the degree to which one question answers another. I will show that relevance is not only a natural generalization of information theory, but also forms its foundation.

    2010-04-01

    The literature suggests children with autism use communication primarily for requests and protests, and almost never for information-seeking. This study investigated whether teaching "Where" questions using intrinsic reinforcement procedures would produce the generalized use of the question, and whether concomitant improvements in related language structures, provided as answers to the children's questions, would occur. In the context of a multiple baseline across participants design, data showed that the children could rapidly acquire and generalize the query, and that there were collateral improvements in the children's use of language structures corresponding to the answers to the questions the children asked. The results are discussed in the context of teaching child initiations to improve linguistic competence in children with autism.

  14. What do Americans know about inequality? It depends on how you ask them

    2012-11-01

    Full Text Available A recent survey of inequality (Norton and Ariely, Perspectives on Psychological Science, 6, 9-12 asked respondents to indicate what percent of the nation's total wealth is---and should be---controlled by richer and poorer quintiles of the U.S. population. We show that such measures lead to powerful anchoring effects that account for the otherwise remarkable findings that respondents reported perceiving, and desiring, extremely low inequality in wealth. We show that the same anchoring effects occur in other domains, namely web page popularity and school teacher salaries. We introduce logically equivalent questions about average levels of inequality that lead to more accurate responses. Finally, when we made respondents aware of the logical connection between the two measures, the majority said that typical responses to the average measures, indicating higher levels of inequality, better reflected their actual perceptions and preferences than did typical responses to percent measures.

    This paper examines if a mere request to a customer – within the frame of a service encounter – to engage in word-of-mouth (WOM) would have an impact on the customer's subsequent WOM activity. Although previous studies have not examined this issue, theoretical arguments do exist. And they point...... in different directions; some suggest a positive impact, while others suggest a negative impact. To explore the issue empirically, we carried out two studies (one survey-based study and one experiment). Both generated the same result: they indicate that merely asking customers to engage in WOM has a positive...... impact on customers' WOM activity. In addition, we found that receiving the request was not negatively associated with the customers' overall evaluations, such as customer satisfaction, which indicates that the potential for negative consequences of making the request seems to be low....

    2015-01-01

    In a single one-hour session, first-year medical students were taught a framework for differentiating between lower-order questions that lead to knowledge of facts and higher-order questions that lead to integration of concepts and deeper learning, thereby preparing them for problem-based learning (PBL). Students generated lists of questions in response to an assertion prompt and categorized them according to Bloom's Taxonomy. These data were analyzed in addition to data from the course exam, which asked them to formulate a higher-level question in response to a prompt. Categorizing questions according to Bloom's Taxonomy was a more difficult task for students than was formulating higher-order questions. Students reported that the skills that they learned were used in subsequent PBL sessions to formulate higher-order learning objectives that integrated new and previously-learned concepts.

Conclusion - The results of the three parts of this study - literature review, study of 1997-2003 statistics, and in-depth collection of statistics for November 2003 - are difficult to compare with each other. However, the general trend emerging from the results is that some kinds of questions asked by health sciences library clients have remained very much the same regardless of the rise of remote end-user searching and the mode of transmission of the questions. These include questions about library policies and services, journal and book holdings, database searching and instructional support. Questions about citation verification and consumer health appear to be decreasing while technical questions and questions about accessing remote databases and online journals are increasing. The majority of reference questions are still asked in person.

  19. The ASK1 gene regulates development and interacts with the UFO gene to control floral organ identity in Arabidopsis.

    1999-09-01

    Normal flower development likely requires both specific and general regulators. We have isolated an Arabidopsis mutant ask1-1 (for -Arabidopsis skp1-like1-1), which exhibits defects in both vegetative and reproductive development. In the ask1-1mutant, rosette leaf growth is reduced, resulting in smaller than normal rosette leaves, and internodes in the floral stem are shorter than normal. Examination of cell sizes in these organs indicates that cell expansion is normal in the mutant, but cell number is reduced. In the mutant, the numbers of petals and stamens are reduced, and many flowers have one or more petals with a reduced size. In addition, all mutant flowers have short stamen filaments. Furthermore, petal/stamen chimeric organs are found in many flowers. These results indicate that the ASK1 gene affects the size of vegetative and floral organs. The ask1 floral phenotype resembles somewhat that of the Arabidopsis ufo mutants in that both genes affect whorls 2 and 3. We therefore tested for possible interactions between ASK1 and UFO by analyzing the phenotypes of ufo-2 ask1-1 double mutant plants. In these plants, vegetative development is similar to that of the ask1-1 single mutant, whereas the floral defects are more severe than those in either single mutant. Interior to the first whorl, the double mutant flowers have more sepals or sepal-like organs than are found in ufo-2, and less petals than ask1-1. Our results suggest that ASK1 interacts with UFO to control floral organ identity in whorls 2 and 3. This is very intriguing because ASK1 is very similar in sequence to the yeast SKP1 protein and UFO contains an F-box, a motif known to interact with SKP1 in yeast. Although the precise mechanism of ASK1 and UFO action is unknown, our results support the hypothesis that these two proteins physically interact in vivo. Copyright 1999 Wiley-Liss, Inc.

    Identification of motor vehicle crash (MVC) characteristics associated with thoracoabdominal injury would advance the development of automatic crash notification systems (ACNS) by improving triage and response times. Our objective was to determine the relationships between MVC characteristics and thoracoabdominal trauma to develop a torso injury probability model. Drivers involved in crashes from 1993 to 2001 within the National Automotive Sampling System were reviewed. Relationships between torso injury and MVC characteristics were assessed using multivariate logistic regression. Receiver operating characteristic curves were used to compare the model to current ACNS models. There were a total of 56,466 drivers. Age, ejection, braking, avoidance, velocity, restraints, passenger-side impact, rollover, and vehicle weight and type were associated with injury (p < 0.05). The area under the receiver operating characteristic curve (83.9) was significantly greater than current ACNS models. We have developed a thoracoabdominal injury probability model that may improve patient triage when used with ACNS.

  3. Anthropological significance of phenylketonuria.

    1975-01-01

    The highest incidence rates of phenylketonuria (PKU) have been observed in Ireland and Scotlant. Parents heterozygous for PKU in Norway differ significantly from the general population in the Rhesus, Kell and PGM systems. The parents investigated showed an excess of Rh negative, Kell plus and PGM type 1 individuals, which makes them similar to the present populations in Ireland and Scotlant. It is postulated that the heterozygotes for PKU in Norway are descended from a completely assimilated sub-population of Celtic origin, who came or were brought here, 1ooo years ago. Bronze objects of Western European (Scottish, Irish) origin, found in Viking graves widely distributed in Norway, have been taken as evidence of Vikings returning with loot (including a number of Celts) from Western Viking settlements. The continuity of residence since the Viking age in most habitable parts of Norway, and what seems to be a nearly complete regional relationship between the sites where Viking graves contain western imported objects and the birthplaces of grandparents of PKUs identified in Norway, lend further support to the hypothesis that the heterozygotes for PKU in Norway are descended from a completely assimilated subpopulation. The remarkable resemblance between Iceland and Ireland, in respect of several genetic markers (including the Rhesus, PGM and Kell systems), is considered to be an expression of a similar proportion of people of Celtic origin in each of the two countries. Their identical, high incidence rates of PKU are regarded as further evidence of this. The significant decline in the incidence of PKU when one passes from Ireland, Scotland and Iceland, to Denmark and on to Norway and Sweden, is therefore explained as being related to a reduction in the proportion of inhabitants of Celtic extraction in the respective populations.

    Full Text Available 1,2-Diarachidonoyl-sn-glycero-3-phosphoethanolamine (DAPE induces both necrosis/necroptosis and apoptosis of NCI-H28 malignant pleural mesothelioma (MPM cells. The present study was conducted to understand the mechanism for DAPE-induced apoptosis of NCI-H28 cells. DAPE induced caspase-independent apoptosis of NCI-H28 malignant pleural mesothelioma (MPM cells, and the effect of DAPE was prevented by antioxidants or an inhibitor of NADPH oxidase (NOX. DAPE generated reactive oxygen species (ROS and inhibited activity of thioredoxin (Trx reductase (TrxR. DAPE decreased an association of apoptosis signal-regulating kinase 1 (ASK1 with thioredoxin (Trx, thereby releasing ASK1. DAPE activated p38 mitogen-activated protein kinase (MAPK, which was inhibited by an antioxidant or knocking-down ASK1. In addition, DAPE-induced NCI-H28 cell death was also prevented by knocking-down ASK1. Taken together, the results of the present study indicate that DAPE stimulates NOX-mediated ROS production and suppresses TrxR activity, resulting in the decrease of reduced Trx and the dissociation of ASK1 from a complex with Trx, allowing sequential activation of ASK1 and p38 MAPK, to induce apoptosis of NCI-H28 MPM cells.

    Full Text Available The concept of "public accountability" is a challenge for political science as a new concept in this area in full debate and developement ,both in theory and practice. This paper is a theoretical approach of displaying some definitions, relevant meanings and significance odf the concept in political science. The importance of this concept is that although originally it was used as a tool to improve effectiveness and eficiency of public governance, it has gradually become a purpose it itself. "Accountability" has become an image of good governance first in the United States of America then in the European Union.Nevertheless,the concept is vaguely defined and provides ambiguous images of good governance.This paper begins with the presentation of some general meanings of the concept as they emerge from specialized dictionaries and ancyclopaedies and continues with the meanings developed in political science. The concept of "public accontability" is rooted in economics and management literature,becoming increasingly relevant in today's political science both in theory and discourse as well as in practice in formulating and evaluating public policies. A first conclusin that emerges from, the analysis of the evolution of this term is that it requires a conceptual clarification in political science. A clear definition will then enable an appropriate model of proving the system of public accountability in formulating and assessing public policies, in order to implement a system of assessment and monitoring thereof.

    2010-01-01

    Deligne constructed a remarkable local system on $\\bP^1-\\{0,\\infty\\}$ attached to a family of Kloosterman sums. Katz calculated its monodromy and asked whether there are Kloosterman sheaves for general reductive groups and which automorphic forms should be attached to these local systems under the Langlands correspondence. Motivated by work of Gross and Frenkel-Gross we find an explicit family of such automorphic forms and even a simple family of automorphic sheaves in the framework of the geometric Langlands program. We use these automorphic sheaves to construct l-adic Kloosterman sheaves for any reductive group in a uniform way, and describe the local and global monodromy of these Kloosterman sheaves. In particular, they give motivic Galois representations with exceptional monodromy groups G_2,F_4,E_7 and E_8. This also gives an example of the geometric Langlands correspondence with wild ramifications for any reductive group.

    2014-03-05

    We performed an ethnomycological study in a community in Tlaxcala, Central Mexico to identify the most important species of wild mushrooms growing in an oak forest, their significance criteria, and to validate the Cultural Significance Index (CSI). Thirty-three mestizo individuals were randomly selected in San Mateo Huexoyucan and were asked seven questions based on criteria established by the CSI. Among the 49 mushroom species collected in the oak forest and open areas, 20 species were mentioned most often and were analyzed in more detail. Ordination and grouping techniques were used to determine the relationship between the cultural significance of the mushroom species, according to a perceived abundance index, frequency of use index, taste score appreciation index, multifunctional food index, knowledge transmission index, and health index. The mushrooms with highest CSI values were Agaricus campestris, Ramaria spp., Amanita aff. basii, Russula spp., Ustilago maydis, and Boletus variipes. These species were characterized by their good taste and were considered very nutritional. The species with the lowest cultural significance included Russula mexicana, Lycoperdon perlatum, and Strobylomyces strobilaceus. The ordination and grouping analyses identified four groups of mushrooms by their significance to the people of Huexoyucan. The most important variables that explained the grouping were the taste score appreciation index, health index, the knowledge transmission index, and the frequency of use index. A. aff. basii and A. campestris were the most significant wild mushrooms to the people of San Mateo. The diversity of the Russula species and the variety of Amanita and Ramaria species used by these people was outstanding. Environments outside the forest also produced useful resources. The CSI used in Oaxaca was useful for determining the cultural significance of mushrooms in SMH, Tlaxcala. This list of mushrooms can be used in conservation proposals for the Quercus

  10. Significance analysis of prognostic signatures.

    Directory of Open Access Journals (Sweden)

    Andrew H Beck

    Full Text Available A major goal in translational cancer research is to identify biological signatures driving cancer progression and metastasis. A common technique applied in genomics research is to cluster patients using gene expression data from a candidate prognostic gene set, and if the resulting clusters show statistically significant outcome stratification, to associate the gene set with prognosis, suggesting its biological and clinical importance. Recent work has questioned the validity of this approach by showing in several breast cancer data sets that "random" gene sets tend to cluster patients into prognostically variable subgroups. This work suggests that new rigorous statistical methods are needed to identify biologically informative prognostic gene sets. To address this problem, we developed Significance Analysis of Prognostic Signatures (SAPS which integrates standard prognostic tests with a new prognostic significance test based on stratifying patients into prognostic subtypes with random gene sets. SAPS ensures that a significant gene set is not only able to stratify patients into prognostically variable groups, but is also enriched for genes showing strong univariate associations with patient prognosis, and performs significantly better than random gene sets. We use SAPS to perform a large meta-analysis (the largest completed to date of prognostic pathways in breast and ovarian cancer and their molecular subtypes. Our analyses show that only a small subset of the gene sets found statistically significant using standard measures achieve significance by SAPS. We identify new prognostic signatures in breast and ovarian cancer and their corresponding molecular subtypes, and we show that prognostic signatures in ER negative breast cancer are more similar to prognostic signatures in ovarian cancer than to prognostic signatures in ER positive breast cancer. SAPS is a powerful new method for deriving robust prognostic biological signatures from clinically

    The prevalence rate and mortality rate of diabetes continue to increase annually. Complications associated with poor control of diabetes include renal dialysis, amputation, heart disease, stroke, retinopathy, and vascular disease, all of which have an impact at the individual, family, and national level. This study compares diabetes self-care behavior and disease control efficacy between attenders and nonattenders of a diabetes support group. We used a questionnaire with good validity and reliability to conduct a cross-sectional survey. Diabetes support groups have been established throughout Taiwan for around 2 years. Participants for this study were recruited randomly from a register of support group participants. Support group instructors were asked to collect questionnaires from those attending and not attending their support groups. Ten groups volunteered to participate in this study. We received 147 valid questionnaires from participants attending support groups (attenders) and 93 questionnaires from participants who did not (nonattenders). There were no statistically significant differences between support group attenders and nonattenders in terms of age, educational level, or time since diagnosis of diabetes. Thus, we assumed these two groups as adequately similar to conduct statistical comparisons. Scores for diabetes self-care behavior, disease control, and use of the diabetes passport were all significantly higher among support group attenders than their nonattender peers. Results indicate that people attending diabetes support groups are more likely to have better self-care behavior and disease control than nonattenders. Therefore, we suggest that the government actively promote policies supportive of diabetes support groups.

    Recent studies have accumulated supporting evidence for in-group advantage in emotion recognition, with individuals more accurately perceiving emotions expressed by cultural in-group members. However, inconsistent results appear in balanced-design studies involving the majority and minority groups residing within a single nation: There is an apparent pattern of an out-group advantage, implying that minority group members show heightened sensitivity toward emotional expressions of the majority group members. Two studies were conducted to further explore why the out-group advantage emerged in multicultural societies. In Study 1, based on a careful review of existing studies involving majority and minority groups, both new and previously reviewed, a new approach to assess the in-group and out-group advantage was proposed and applied. In Study 2, the minority out-group advantage was further tested in an experimental study. European American and Asian American students were asked to identify emotions of European and Asian Americans presented in static photos of imitated emotional expressions and full-channel video presentations of spontaneous emotional expressions. The results revealed that a mutual in-group advantage was observed in the spontaneous expressions condition, but not in the imitated expression condition. Significance and implications of the findings from this study are discussed regarding intergroup interactions in a multicultural society.

  15. What can we learn about postnatal care in Ghana if we ask the right questions? A qualitative study

    Zelee Hill

    2015-09-01

    Full Text Available Background: There are increasing efforts to monitor progress in maternal and neonatal care, with household surveys the main mode of data collection. Postnatal care (PNC is considered a priority indicator yet few countries report on it, and the need to improve the construct validity associated with PNC questions is recognized. Objectives: To determine women's knowledge of what happens to the baby after delivery, women's comprehension of terms and question phrasing related to PNC, and issues with recall periods. Design: Forty qualitative interviews and four focus group discussions were conducted with mothers, and 10 interviews with health workers in rural Ghana. Data were collected on knowledge and recall of postnatal health checks and language used to describe these health checks. Results: Mothers required specific probing using appropriate language to report postnatal checks. They only had adequate knowledge of postnatal checks, which were easily observed or required asking them a question. Respondents reported that health workers rarely communicated with mothers about what they were doing, and most women did not know the purpose of the equipment used during health checks, such as why a thermometer was being used. Knowledge of neonatal checks in the first hours after a facility delivery was low if the mother and child were separated, or if the mother was tired or weak. Many women reported that they could remember events clearly, but long recall periods affected reporting for some, especially those who had multiple checks or for those with no problems. Conclusions: Direct questions about PNC or health checks are likely to underestimate coverage. Validity of inferences can be enhanced by using appropriate verbal probes during surveys on commonly performed checks that are clear and visible to the mother.

  18. Did HIV contribute to the breakdown of society in Rwanda? A question worth asking.

    Science.gov (United States)

    1994-01-01

    Rwanda may represent the first example of an entire society breaking down because of the prevalence of AIDS. It was known that infection rates in Rwanda were among the highest in the world, yet few Rwandans, even those tested, were given a diagnosis. Analysts believe that this situation led to feelings of fear and despair which fueled the recent violence. It has been estimated that as many as 70% of sex workers, 30-40% of pregnant women, and 4-65% of soldiers were infected. The disease decimated the officer corps, leaving an unstable leadership and a lack of discipline. In addition, although 98% of the people in Rwanda were aware of the epidemic, only 5% changed their behavior as a result of this knowledge. Because the government failed to acknowledge AIDS as a problem, public discussion was prohibited. It is instructive that when the atrocities began, HIV/AIDS workers were among the first to be murdered. Although it will be impossible to pinpoint the amount of influence that this epidemic had on the breakdown of civilization in Rwanda, it is important to ask this question. Attention is also being paid to the appropriate strategies for dealing with AIDS in postwar conditions. Is it reasonable to hand out condoms, for example, to a population struggling with cholera? Also, how can AIDS awareness be maintained in a country which must deal with repairing the far-reaching damages of war?

    To understand and analyze what young Italian males attending high school would like to ask andrologists but do not know how to or do not have the courage to do so. As part of our "Androlife" campaign, we invited 1565 students attending the last year of high school to participate in our research. Firstly, they attended a lesson on general and andrological health and then, on a voluntary basis, they responded to a survey and were subjected to a preventive andrological visit. The data analysis showed that the main topics in which young people are interested are: sexual activity and sexuality, sexually transmitted diseases, andrological health and fertility, and lifestyle. This study highlights that young people are very interested in sexual health issues and that they have specific needs and interests with regard to sexual health information. Public education campaigns such as Androlife should be supported and further improved on the basis of the advice received by young participants. Sexual and reproductive health education targeting adolescents and young adults represent the basis both for wellness and for fertility preservation, and thus benefits of increased support to educational campaigns would be apparent not only in terms of individual health but also in terms of cost reduction in public spending.

    Consumption of benzodiazepines (BZDs) is common among seniors. When used over a long period of time, BZDs can induce dependence. The present study aimed to equip nurses with valid screening questions for detecting BZD dependence among seniors, applicable to clinical practice and based on the DSM-IV-TR version. A random sample of 707 BZD users aged 65 years and over was screened for BZD dependence using the DSM-IV-TR criteria for substance dependence. To predict a diagnosis of BZDs dependence, sensitivity and specificity were computed for each pair of items. Results showed that an affirmative answer to 'Have you try to stop taking this medication?' and 'Over the past 12 months, have you noticed any decrease in the effect of this medication?' led to a sensitivity of 97.1% and a specificity of 94.9% to detect BZD dependence. Asking these two simple questions can be easily integrated into clinical practice and have considerable potential for identifying cases of BZD dependence.

    The solution of distributed mutual exclusion is difficult in Ad hoc networks owing to dynamic topologies and mobility.Based on the analysis of the properties of Ad hoc networks and the disadvantages of the traditional algorithms, an improved Ad hoc system model was given and a novel algorithm was presented as AHDME (Ad Hoc Distributed Mutual Exclusion); it was based on the token-asking algorithms.It utilized broadcast to search for the token and to decrease the message complexity of multi-hop Ad hoc networks.Lamport's timestamp was improved to ensure the time sequence and to prevent nodes from starvation.When compared to traditional algorithms, AHDME does not require the fixed size of request queues and the global system information, which adapts itself to the frequent arrival/departures and the limited computing capability of nodes in Ad hoc networks.Performance analysis and simulation results show that the AHDME algorithm has low message complexity, small space complexity, and short response delay.

    The ability to categorize information is essential to everyday tasks such as identifying the cause of an event given a set of likely explanations or pinpointing the correct from a set of possible diagnoses by sequentially probing questions. In three studies, we investigated how the level of inclusiveness at which objects are presented (basic-level vs. subordinate-level) influences children's (7- and 10-year-olds) and adults' performance in a sequential binary categorization task. Study 1 found a robust facilitating effect of basic-level objects on the ability to ask effective questions in a computerized version of the Twenty Questions game. Study 2 suggested that this facilitating effect might be due to the kinds of object-differentiating features participants generate when provided with basic-level as compared to subordinate-level objects. Study 3 ruled out the alternative hypothesis that basic-level objects facilitate the selection of the most efficient among a given set of features. PMID:26217262

    Written by one of the subject’s foremost experts, this book focuses on the central developments and modern methods of the advanced theory of abelian groups, while remaining accessible, as an introduction and reference, to the non-specialist. It provides a coherent source for results scattered throughout the research literature with lots of new proofs. The presentation highlights major trends that have radically changed the modern character of the subject, in particular, the use of homological methods in the structure theory of various classes of abelian groups, and the use of advanced set-theoretical methods in the study of undecidability problems. The treatment of the latter trend includes Shelah’s seminal work on the undecidability in ZFC of Whitehead’s Problem; while the treatment of the former trend includes an extensive (but non-exhaustive) study of p-groups, torsion-free groups, mixed groups, and important classes of groups arising from ring theory.

    Tumor necrosis factor-α (TNF-α) is a pro-inflammatory cytokine produced by monocytes/macrophage that plays a pathological role in rheumatoid arthritis (RA). In this study, we investigate the effect of thymoquinone (TQ), a phytochemical found in Nigella sativa, in regulating TNF-α-induced RA synovial fibroblast (RA-FLS) activation. Treatment with TQ (1–5 μM) had no marked effect on the viability of human RA-FLS. Pre-treatment of TQ inhibited TNF-α-induced interleukin-6 (IL-6) and IL-8 production and ICAM-1, VCAM-1, and cadherin-11 (Cad-11) expression in RA-FLS (p < 0.01). Evaluation of the signaling events showed that TQ inhibited TNF-α-induced phospho-p38 and phospho-JNK expression, but had no inhibitory effect on NF-κB pathway, in RA-FLS (p < 0.05; n = 4). Interestingly, we observed that selective down-regulation of TNF-α-induced phospho-p38 and phospho-JNK activation by TQ is elicited through inhibition of apoptosis-regulated signaling kinase 1 (ASK1). Furthermore, TNF-α selectively induced phosphorylation of ASK1 at Thr845 residue in RA-FLS, which was inhibited by TQ pretreatment in a dose dependent manner (p < 0.01). Pre-treatment of RA-FLS with ASK1 inhibitor (TC ASK10), blocked TNF-α induced expression of ICAM-1, VCAM-1, and Cad-11. Our results suggest that TNF-α-induced ASK1-p38/JNK pathway is an important mediator of cytokine synthesis and enhanced expression of adhesion molecule in RA-FLS and TQ, by selectively inhibiting this pathway, may have a potential therapeutic value in regulating tissue destruction observed in RA. - Highlights: • Evolving evidence suggests that ASK1 plays a central role in rheumatic arthritis (RA). • TNF-α activates ASK1, which regulate downstream signaling through JNK/p38 activation in RA-FLS. • ASK1 may be used as a potential therapeutic target in RA. • Thymoquinone was able to selectively inhibit TNF-α-induced phosphorylation of ASK1 in RA-FLS. • Thymoquinone might serve as a potential small

    APOBEC3G (A3G) is an innate antiviral restriction factor that strongly inhibits the replication of human immunodeficiency virus type 1 (HIV-1). An HIV-1 accessory protein, Vif, hijacks the host ubiquitin-proteasome system to execute A3G degradation. Identification of the host pathways that obstruct the action of Vif could provide a new strategy for blocking viral replication. We demonstrate here that the host protein ASK1 (apoptosis signal-regulating kinase 1) interferes with the counteraction by Vif and revitalizes A3G-mediated viral restriction. ASK1 binds the BC-box of Vif, thereby disrupting the assembly of the Vif-ubiquitin ligase complex. Consequently, ASK1 stabilizes A3G and promotes its incorporation into viral particles, ultimately reducing viral infectivity. Furthermore, treatment with the antiretroviral drug AZT (zidovudine) induces ASK1 expression and restores the antiviral activity of A3G in HIV-1-infected cells. This study thus demonstrates a distinct function of ASK1 in restoring the host antiviral system that can be enhanced by AZT treatment.

    The amyloid precursor protein (APP) is a type I transmembrane protein translocated to neuronal terminals, whose function is still unknown. The C-terminus of APP mediates its interaction with cellular adaptor and signaling proteins, some of which signal to the stress-activated protein kinase (SAPK) pathway. Here we show that ASK1, a MAPKKK that activates two SAPKs, c-Jun N-terminal-kinase (JNK) and p38, is present in a complex containing APP, phospho-MKK6, JIP1 and JNK1. In primary neurons deprived of growth factors, as well as in brains of (FAD)APP-transgenic mice, ASK1 was upregulated in neuronal projections, where it interacted with APP. In non-transgenic brains, ASK1 and APP associated mainly in the ER. Our results indicate that recruitment of ASK1 to stress-signaling complexes assembled with APP may be triggered and enhanced by cellular stress. Thus, ASK1 may be the apical MAPKKK in a signaling complex assembled with APP as a response to stress. PMID:17719230

    Full Text Available How is movement of individuals coordinated as a group? This is a fundamental question of social behaviour, encompassing phenomena such as bird flocking, fish schooling, and the innumerable activities in human groups that require people to synchronise their actions. We have developed an experimental paradigm, the HoneyComb computer-based multi-client game, to empirically investigate human movement coordination and leadership. Using economic games as a model, we set monetary incentives to motivate players on a virtual playfield to reach goals via players' movements. We asked whether (I humans coordinate their movements when information is limited to an individual group member's observation of adjacent group member motion, (II whether an informed group minority can lead an uninformed group majority to the minority's goal, and if so, (III how this minority exerts its influence. We showed that in a human group--on the basis of movement alone--a minority can successfully lead a majority. Minorities lead successfully when (a their members choose similar initial steps towards their goal field and (b they are among the first in the whole group to make a move. Using our approach, we empirically demonstrate that the rules of swarming behaviour apply to humans. Even complex human behaviour, such as leadership and directed group movement, follow simple rules that are based on visual perception of local movement.

In the present study, we show that a novel chromone derivative, DCO-6, significantly reduced lipopolysaccharide (LPS-induced production of nitric oxide, IL-1β and IL-6, decreased the levels of iNOS, IL-1β and IL-6 mRNA expression in both RAW264.7 cells and mouse primary peritoneal macrophages, and inhibited LPS-induced activation of p38 MAPK but not of JNK, ERK. Moreover, DCO-6 specifically inhibited TLR4-dependent p38 activation without directly inhibiting its kinase activity. LPS-induced production of intracellular reactive oxygen species (ROS was remarkably impaired by DCO-6, which disrupted the formation of the TRAF6-ASK1 complex. Administering DCO-6 significantly protected mice from LPS-induced septic shock in parallel with the inhibition of p38 activation and ROS production. Our results indicate that DCO-6 showed anti-inflammatory properties through inhibition of ROS-dependent activation of TRAF6-ASK1-p38 pathway. Blockade of the upstream events required for p38 MAPK action by DCO-6 may provide a new therapeutic option in the treatment of inflammatory diseases.

    In recent years the amount of digital data in the world has risen immensely. But, the more information exists, the greater is the possibility of its unwanted disclosure. Thus, the data privacy protection has become a pressing problem of the present time. The task of individual privacy-preserving is being thoroughly studied nowadays. At the same time, the problem of statistical disclosure control for collective (or group) data is still open. In this paper we propose an effective and relatively simple (wavelet-based) way to provide group anonymity in collective data. We also provide a real-life example to illustrate the method.

  18. How long did it last? You’d better ask a human

    Full Text Available In the future, human-like robots will live among people to provide company and help carrying out tasks in cooperation with humans. These interactions require that robots understand not only human actions, but also the way in which we perceive the world. Human perception heavily relies on the time dimension, especially when it comes to processing visual motion. Critically, human time perception for dynamic events is often inaccurate. Robots interacting with humans may want to see the world and tell time the way humans do: if so, they must incorporate human-like fallacy. Observers asked to judge the duration of brief scenes are prone to errors: perceived duration often does not match the physical duration of the event. Several kinds of temporal distortions have been described in the specialized literature. Here we review the topic with a special emphasis on our work dealing with time perception of animate actors versus inanimate actors. This work shows the existence of specialized time bases for different categories of targets. The time base used by the human brain to process visual motion appears to be calibrated against the specific predictions regarding the motion of human figures in case of animate motion, while it can be calibrated against the predictions of motion of passive objects in case of inanimate motion. Human perception of time appears to be strictly linked with the mechanisms used to control movements. Thus, neural time can be entrained by external cues in a similar manner for both perceptual judgments of elapsed time and in motor control tasks. One possible strategy could be to implement in humanoids a unique architecture for dealing with time, which would apply the same specialized mechanisms to both perception and action, similarly to humans. This shared implementation might render the humanoids more acceptable to humans, thus facilitating reciprocal interactions.

    Instagram. Pinterest. SoundCloud. Storify. Almost every month there's a new platform through which institutions could potentially promote their work. If used effectively, these less-conventional means of communication can indeed be powerful devices to connect scientists and the general public, especially for small institutions with limited resources. We discuss our experiences on Reddit, a social news site, and Projeqt, a visual storytelling platform. We'll talk about the pros and cons of using them, and provide tips on what to do and what to avoid for those interested in having a go. Nearly 1.5 million people post on Reddit daily. One of the most active sections is "Ask Me Anything", where individuals can share expertise and insights. AMAs are essentially online town-hall style meetings. Movie stars host AMAs, as do politicians, athletes, and increasingly, scientists. In fact, the science subtopic is the 6th most subscribed on the site. Forecaster Tony Barnston, from the International Research Institute for Climate and Society hosted an AMA in June 2012. The session generated >200 comments and questions in 24 hours. Barnston was surprisingly pleased with the experience. "I liked having time to think about my answers," he said, noting this type of engagement could be attractive to scientists who might feel anxious about interacting with the public. Projeqt is a creative visual storytelling platform that allows one to integrate activity from a host of social media such as Twitter, Facebook, Flickr, Instagram, YouTube and more. In very short time, an institution can produce a beautiful visual narrative of its research and activities, combining its own in-house content with creative-commons content easily available on the web. The resulting product is itself shareable and embeddable.; Barnston in office where he took questions via Reddit. (Photo: B.

    Full Text Available Abstract Background Adolescents with intellectual disability often have poor health and healthcare. This is partly as a consequence of poor communication and recall difficulties, and the possible loss of specialised paediatric services. Methods/Design A cluster randomised trial was conducted with adolescents with intellectual disability to investigate a health intervention package to enhance interactions among adolescents with intellectual disability, their parents/carers, and general practitioners (GPs. The trial took place in Queensland, Australia, between February 2007 and September 2010. The intervention package was designed to improve communication with health professionals and families’ organisation of health information, and to increase clinical activities beneficial to improved health outcomes. It consisted of the Comprehensive Health Assessment Program (CHAP, a one-off health check, and the Ask Health Diary, designed for on-going use. Participants were drawn from Special Education Schools and Special Education Units. The education component of the intervention was delivered as part of the school curriculum. Educators were surveyed at baseline and followed-up four months later. Carers were surveyed at baseline and after 26 months. Evidence of health promotion, disease prevention and case-finding activities were extracted from GPs clinical records. Qualitative interviews of educators occurred after completion of the educational component of the intervention and with adolescents and carers after the CHAP. Discussion Adolescents with intellectual disability have difficulty obtaining many health services and often find it difficult to become empowered to improve and protect their health. The health intervention package proposed may aid them by augmenting communication, improving documentation of health encounters, and improving access to, and quality of, GP care.

    Full Text Available Abstract Background As the number of randomised controlled trials of medicines for children increases, it becomes progressively more important to understand the experiences of parents who are asked to enrol their child in a trial. This paper presents a narrative review of research evidence on parents' experiences of trial recruitment focussing on qualitative research, which allows them to articulate their views in their own words. Discussion Parents want to do their best for their children, and socially and legally their role is to care for and protect them yet the complexities of the medical and research context can challenge their fulfilment of this role. Parents are simultaneously responsible for their child and cherish this role yet they are dependent on others when their child becomes sick. They are keen to exercise responsibility for deciding to enter a child in a trial yet can be fearful of making the 'wrong' decision. They make judgements about the threat of the child's condition as well as the risks of the trial yet their interpretations often differ from those of medical and research experts. Individual pants will experience these and other complexities to a greater or lesser degree depending on their personal experiences and values, the medical situation of their child and the nature of the trial. Interactions at the time of trial recruitment offer scope for negotiating these complexities if practitioners have the flexibility to tailor discussions to the needs and situation of individual parents. In this way, parents may be helped to retain a sense that they have acted as good parents to their child whatever decision they make. Summary Discussing randomised controlled trials and gaining and providing informed consent is challenging. The unique position of parents in giving proxy consent for their child adds to this challenge. Recognition of the complexities parents face in making decisions about trials suggests lines for future

    Quercetin is a natural plant flavonoid that has been reported to possess a wide range of beneficial health effects, including anti-cancer and anti-inflammatory activities. Glycosylation of natural flavonoids with various sugar moieties can affect their physical, chemical, and biological properties. In this study, quercetin 3-O-xyloside (Quer-xyl) was enzymatically synthesized, and the immunomodulatory activities of quercetin and Quer-xyl were evaluated and compared. The results showed that Quer-xyl more effectively induced the secretion of TNF-α and IL-6 than quercetin by 2.5 and 1.5-fold, respectively. Quer-xyl dose-dependently induced the inducible nitric oxide synthase (iNOS) expression and increased the production of nitric oxide (NO) 1.3-fold more than quercetin. Quer-xyl also increased the phosphorylation of ASK1 and MAPKs (JNK and p38). Treatment with NQDI-1 (an inhibitor of ASK1) significantly attenuated the Quer-xyl-induced up-regulation of TNF-α secretion. The activation and subsequent nuclear translocation of NF-κB were substantially enhanced upon treatment with Quer-xyl (2.5-20 μM), while NQDI-1 treatment blocked the nuclear translocation of NF-κB. These results demonstrated that Quer-xyl can enhance the early innate immunity more effectively than quercetin by activating macrophages to secrete TNF-α and IL-6 through up-regulation of the redox-dependent ASK1/MAPK/NF-κB signaling pathway, suggesting for the first time that Quer-xyl may represent a new immunostimulator.

    (1) To compare staff members' opinions of long-term care (LTC) residents' ability to complete a customer satisfaction survey (CSS) with a measure of cognition (MDS-COGS) derived from Minimum Data Set data; and (2) to examine the association between CSS answer reliability and MDS-COGS score. Retrospective comparison of the staff's assessment and MDS-COGS score for each respondent, as well as a prospective comparison of MDS-COGS scores with reliability measures from repeated survey administration. A 100-bed Veterans Affairs (VA) nursing home. We administered a CSS designed by our VA network following an assigned protocol. We later calculated each respondent's MDS-COGS score (grouped into 4 categories) and compared it with the staff's opinion of whether that resident was "capable of responding" (yes/no) to a CSS. We subsequently modified the CSS for low reading level and low vision, and randomly selected 40 LTC residents for repeated survey administration (T1 and T2 1 week later). Test-retest reliability was estimated by examining the extent to which T1 and T2 answers agreed (agreed exactly; meaningfully agreed as defined by VA network personnel who designed the survey; or meaningfully agreed as decided by paper authors). Staff judged that 25 of 76 LTC residents were not and 51 of 76 were capable of responding to the CSS. In 82% of cases, MDS-COGS score category and staff opinion agreed ("no cognitive impairment"/"mild-moderate cognitive impairment" with "able to complete"; and "moderate-severe cognitive impairment"/"severe cognitive impairment" with "unable to complete"). Cohen's kappa was 0.57 with a P value of survey administration, 32 successfully completed surveys at T1 and T2. Higher MDS-COGS scores, suggesting greater cognitive impairment, were significantly associated with lower answer reliability. The answers given by LTC residents changed meaningfully (by network criteria) from T1 to T2 by 12%, 27%, and 28% across categories of no-to-mild cognitive

  5. 'Asking the Right Question'. A Comparison of Two Approaches to Gathering Data on 'Herbals' Use in Survey Based Studies.

    Directory of Open Access Journals (Sweden)

    James S McLay

    Full Text Available Over the last decade academic interest in the prevalence and nature of herbal medicines use by pregnant women has increased significantly. Such data are usually collected by means of an administered questionnaire survey, however a key methodological limitation using this approach is the need to clearly define the scope of 'herbals' to be investigated. The majority of published studies in this area neither define 'herbals' nor provide a detailed checklist naming specific 'herbals' and CAM modalities, which limits inter-study comparison, generalisability and the potential for meta-analyses. The aim of this study was to compare the self-reported use of herbs, herbal medicines and herbal products using two different approaches implemented in succession.Cross-sectional questionnaire surveys of women attending for their mid-trimester scan or attending the postnatal unit following live birth at the Royal Aberdeen Maternity Hospital, North-East Scotland. The questionnaire utilised two approaches to collect data on 'herbals' use, a single closed yes/no answer to the question "have you used herbs, herbal medicines and herbal products in the last three months"; and a request to tick which of a list of 40 'herbals' they had used in the same time period.A total of 889 responses were obtained of which 4.3% (38 answered 'yes' to herbal use via the closed question. However, using the checklist 39% (350 of respondents reported the use of one or more specific 'herbals' (p<0.0001. The 312 respondents who reported 'no' to 'herbals' use via the closed question but "yes" via the checklist consumed a total of 20 different 'herbals' (median 1, interquartile range 1-2, range 1-6.This study demonstrates that the use of a single closed question asking about the use of 'herbals', as frequently reported in published studies, may not yield valid data resulting in a gross underestimation of actual use.

    Full Text Available As teachers, we well understand the need for activities that help develop critical-thinking skills in microbiology. In our experience, one concept that students have difficulty understanding is transcriptional regulation of bacterial genes. To help with this, we developed and evaluated a paper-based activity to help students understand and apply the concepts of bacterial transcriptional regulation. While we don't identify it as such, we use a complementation experiment to assess student understanding of how regulation changes when new DNA is introduced. In Part 1 of this activity, students complete an open book, take-home assignment that asks them to define common terminology related to regulation, and draw the regulatory components of different scenarios involving positive and negative regulation. In Part 2, students work in small groups of 3-4 to depict the regulatory components for a different scenario. They are asked to explain the results of a complementation experiment based on this scenario. They then predict the results of a slightly different experiment. Students who completed the Regulation Activity did significantly better on post-test questions related to regulation, compared to pre-test questions.

  10. MicroRNA-Mediated Down-Regulation of Apoptosis Signal-Regulating Kinase 1 (ASK1 Attenuates the Apoptosis of Human Mesenchymal Stem Cells (MSCs Transplanted into Infarcted Heart

    Full Text Available Stem cell therapy using adult stem cells, such as mesenchymal stem cells (MSCs has produced some promising results in treating the damaged heart. However, the low survival rate of MSCs after transplantation is still one of the crucial factors that limit the therapeutic effect of stem cells. In the damaged heart, oxidative stress due to reactive oxygen species (ROS production can cause the death of transplanted MSCs. Apoptosis signal-regulating kinase 1 (ASK1 has been implicated in the development of oxidative stress-related pathologic conditions. Thus, we hypothesized that down-regulation of ASK1 in human MSCs (hMSCs might attenuate the post-transplantation death of MSCs. To test this hypothesis, we screened microRNAs (miRNAs based on a miRNA-target prediction database and empirical data and investigated the anti-apoptotic effect of selected miRNAs on human adipose-derived stem cells (hASCs and on rat myocardial infarction (MI models. Our data indicated that miRNA-301a most significantly suppressed ASK1 expression in hASCs. Apoptosis-related genes were significantly down-regulated in miRNA-301a-enriched hASCs exposed to hypoxic conditions. Taken together, these data show that miRNA-mediated down-regulation of ASK1 protects MSCs during post-transplantation, leading to an increase in the efficacy of MSC-based cell therapy.

  11. Stick with your group: young children's attitudes about group loyalty.

    2014-10-01

    For adults, loyalty to the group is highly valued, yet little is known about how children evaluate loyalty. We investigated children's attitudes about loyalty in a third-party context. In the first experiment, 4- and 5-year-olds watched a video of two groups competing. Two members of the losing group then spoke. The disloyal individual said she wanted to win and therefore would join the other group. The loyal individual said she also wanted to win but would stay with her group. Children were then asked five forced-choice questions about these two individuals' niceness, trustworthiness, morality, and deservingness of a reward. The 5-year-olds preferred the loyal person across all questions; results for the 4-year-olds were considerably weaker but in the same direction. The second experiment investigated the direction of the effect in 5-year-olds. In this experiment, children answered questions about either a loyal individual, a disloyal individual, or a neutral individual. Children rated both the loyal and neutral individuals more positively than the disloyal individual across a number of measures. Thus, whereas disloyal behavior is evaluated unfavorably by children, loyal behavior is the expected norm. These results suggest that, at least from 5 years of age, children understand that belonging to a group entails certain commitments. This marks an important step in their own ability to negotiate belonging and become trustworthy and reliable members of their social groups.

    2015-05-01

    Full Text Available Hyperglycemia results in oxidative stress and leads to neuronal apoptosis in the brain. Diabetes studies show that microglia participate in the progression of neuropathogenesis through their involvement in inflammation in vivo and in vitro. In high-glucose-induced inflammation, apoptosis signal regulating kinase 1 (ASK1 triggers the release of apoptosis cytokines and apoptotic gene expression. MicroRNA-Let7A (miR-Let7A is reported to be a regulator of inflammation. In the present study, we investigated whether miR-Let7A regulates the function of microglia by controlling ASK1 in response to high-glucose-induced oxidative stress. We performed reverse transcription polymerase chain reaction, Taqman assay, real-time polymerase chain reaction, and immunocytochemistry to confirm the alteration of microglia function. Our results show that miR-Let7A is associated with the activation of ASK1 and the expression of anti-inflammatory cytokine (interleukin (IL-10 and Mycs (c-Myc and N-Myc. Thus, the relationship between Let-7A and ASK1 could be a novel target for enhancing the beneficial function of microglia in central nervous system disorders.

    The zinc-finger protein A20 has crucial physiological functions as a dual inhibitor of nuclear factor-κB (NF-κB) activation and apoptosis in tumor necrosis factor (TNF) receptor 1 signaling pathway. Although the molecular basis for the anti-NF-κB function of A20 has been well elucidated, the anti-apoptotic function of A20 is largely unknown. Here, we report a novel mechanism underlying the anti-apoptotic function of A20: A20 blocks TNF-induced apoptosis through suppression of c-jun N-terminal kinase (JNK) by targeting apoptosis signal-regulating kinase1 (ASK1). First, the ectopic expression of A20 drastically inhibits TNF-induced JNK activation and apoptosis in multiple cell types including those deficient of NF-κB activation. Unexpectedly, the blunting effect of A20 on TNF-induced JNK activation is not mediated by affecting the TNFR1 signaling complex formation. Instead, A20 interacts with ASK1, an important MAPKK kinase in the JNK signaling cascade. More importantly, overexpression of wild-type A20, but not of mutant A20 (ZnF4; C624A, C627A), promotes degradation of the ASK1 through the ubiquitin-proteasome system. Taken together, the results from this study reveal a novel anti-apoptotic mechanism of A20 in TNF signaling pathway: A20 binds to ASK1 and mediates ASK1 degradation, leading to suppression of JNK activation and eventually blockage of apoptosis.

  12. Thymoquinone inhibits TNF-α-induced inflammation and cell adhesion in rheumatoid arthritis synovial fibroblasts by ASK1 regulation

    2015-01-01

    Tumor necrosis factor-α (TNF-α) is a pro-inflammatory cytokine produced by monocytes/macrophage that plays a pathological role in rheumatoid arthritis (RA). In this study, we investigate the effect of thymoquinone (TQ), a phytochemical found in Nigella sativa, in regulating TNF-α-induced RA synovial fibroblast (RA-FLS) activation. Treatment with TQ (1–5 μM) had no marked effect on the viability of human RA-FLS. Pre-treatment of TQ inhibited TNF-α-induced interleukin-6 (IL-6) and IL-8 production and ICAM-1, VCAM-1, and cadherin-11 (Cad-11) expression in RA-FLS (p<0.01). Evaluation of the signaling events showed that TQ inhibited TNF-α-induced phospho-p38 and phospho-JNK expression, but had no inhibitory effect on NF-κB pathway, in RA-FLS (p<0.05; n=4). Interestingly, we observed that selective down-regulation of TNF-α-induced phospho-p38 and phospho-JNK activation by TQ is elicited through inhibition of apoptosis-regulated signaling kinase 1 (ASK1). Furthermore, TNF-α selectively induced phosphorylation of ASK1 at Thr845 residue in RA-FLS, which was inhibited by TQ pretreatment in a dose dependent manner (p<0.01). Pre-treatment of RA-FLS with ASK1 inhibitor (TC ASK10), blocked TNF-α induced expression of ICAM-1, VCAM-1, and Cad-11. Our results suggest that TNF-α-induced ASK1-p38/JNK pathway is an important mediator of cytokine synthesis and enhanced expression of adhesion molecule in RA-FLS and TQ, by selectively inhibiting this pathway, may have a potential therapeutic value in regulating tissue destruction observed in RA.

  13. Combined use of the ASK and SHK-1 cell lines to enhance the detection of infectious salmon anemia virus

    Infectious salmon anemia (ISA) is a severe disease primarily affecting commercially farmed Atlantic salmon (Salmo salar) in seawater. The disease has been reported in portions of Canada, the United Kingdom, the Faroe Islands, and the United States. Infectious salmon anemia virus (ISAV), the causative agent of ISA, has also been isolated from several asymptomatic marine and salmonid fish species. Diagnostic assays for the detection of ISAV include virus isolation in cell culture, a reverse transcriptase-PCR, an enzyme-linked immunosorbent assay, and an indirect fluorescent antibody test. Virus isolation is considered the gold standard, and 5 salmonid cell lines are known to support growth of ISAV. In this study, the relative performance of the salmon head kidney 1 (SHK-1), Atlantic salmon kidney (ASK), and CHSE-214 cell lines in detecting ISAV was evaluated using samples from both experimentally and naturally infected Atlantic salmon. Interlaboratory comparisons were conducted using a quality control-quality assurance ring test. Both the ASK and SHK-1 cell lines performed well in detecting ISAV, although the SHK-1 line was more variable in its sensitivity to infection and somewhat slower in the appearance of cytopathic effect. Relative to the SHK-1 and ASK lines, the CHSE-214 cell line performed poorly. Although the ASK line appeared to represent a good alternative to the more commonly used SHK-1 line, use of a single cell line for diagnostic assays may increase the potential for false-negative results. Thus, the SHK-1 and ASK cell lines can be used in combination to provide enhanced ability to detect ISAV.

  14. How do guide dogs and pet dogs (Canis familiaris) ask their owners for their toy and for playing?

    When apes are not fully understood by humans, they persist with attempts to communicate, elaborating their behaviours to better convey their meaning. Such abilities have never been investigated in dogs. The present study aimed to clarify any effect of the visual attentional state of the owner on dogs' (Canis familiaris) social-communicative signals for interacting with humans, and to determine whether dogs persist and elaborate their behaviour in the face of failure to communicate a request. Gaze at a hidden target or at the owner, gaze alternation between a hidden target and the owner, vocalisations and contacts in 12 guide and 12 pet dogs were analysed (i) when the dogs were asked by their owners (blind or sighted) to fetch their inaccessible toy and (ii) when the dogs were subsequently given an unfamiliar object (apparent unsuccessful communication) or their toy (apparent successful communication). No group differences were found, indicating no effect of the visual status of the owner on the dogs' socio-communicative modes (i.e. no sensitivity to human visual attention). Results, however, suggest that the dogs exhibited persistence (but not elaboration) in their "showing" behaviours in each condition, except that in which the toy was returned. Thus, their communication was about a specific item in space (the toy). The results suggest that dogs possess partially intentional non-verbal deictic abilities: (i) to get their inaccessible toy, the dogs gazed at their owners as if to trigger their attention; gaze alternation between the owner and the target direction, and two behaviours directed at the target were performed, apparently to indicate the location of the hidden toy; (ii) after the delivery of the toy, the dogs behaved as if they returned to the play routine, gazing at their owner whilst holding their toy. In conclusion, this study shows that dogs possess partially intentional non-verbal deictic abilities: they exhibit successive visual orienting between a

    The Hoh Xil basin, which is the largest Tertiary sedimentary basin in the hinterland of the Tibet plateau, isbounded on the north margin by the Kunlun Mountains and the South Kunlun suture zone, and on the south mar-gin by the Tanggula Mountains and the Kangbataqing fault. The basin contains a Tertiary sediment pile of approx-imately 5.4 km thick of fluvial mudstone, sanadstone, and conglomerate and 0.4 km thick of limestone, which wasreported to have a closed relationship with the continental collision and early uplift of the Tibet plateau. From low-er to upper, the Tertiary sediments include the Early Eocene to Early Oligocene Fenghuoshan Group, the EarlyOligocene Yaxicuo Group, and the Early Miocene Wudaoliang Group. Here we clarify the facies analysis of theYaxicuo Group, which was magnetostratigraphically dated as 32.0 - 30.0 Ma, and discuss its paleoclimatic signifi-cance. The Yaxicuo Group is 670.0 m thick and consists mainly of violet alternating sandstone and mudstone withintercalated gray layered and tubercular gypsolith. The standard section GG2 of the Yaxicuo Group is situated inthe southern part of the Wudaoliang area of the Hoh Xil basin. The Yaxicuo Group consists mainly of lacustrine fa-cies, but contains fluvial facies in the lower-middle part. The lacustrine facies includes shore, shallow lake, andsalt lake subfacies. They are characterized by coarsening and thickening upward of sandstone and siltstone. Thefluvial facies consists of point bars, natural levees, and flood plains and is characterized by sandstone and conglom-erate that fine and thin upward. Paleocurrent directions were measured from sedimentary structures of, for exam-ples, lamination, planar cross- bedding, parallel bedding, and climbing - ripple cross - lamination. They indicatethat the depocenter of the Hoh Xil basin was migrated eastward and northward during the period of 32.0 - 30.0Ma.

    Contrast-induced nephropathy (CIN) is a leading cause of hospital-acquired acute kidney injury (AKI) due to apoptosis induced in renal tubular cells. Our previous study demonstrated the novel N-acetylcysteine amide (NACA); the amide form of N-acetyl cysteine (NAC) prevented renal tubular cells from contrast-induced apoptosis through inhibiting p38 MAPK pathway in vitro. In the present study, we aimed to compare the efficacies of NACA and NAC in preventing CIN in a well-established rat model and investigate whether thioredoxin-1 (Trx1) and apoptosis signal-regulating kinase 1 (ASK1) act as the potential activator for p38 MAPK. NACA significantly attenuated elevations of serum creatinine, blood urea nitrogen, and biomarkers of AKI. At equimolar concentration, NACA was more effective than NAC in reducing histological changes of renal tubular injuries. NACA attenuated activation of p38 MAPK signal, reduced oxidative stress, and diminished apoptosis. Furthermore, we demonstrated that contrast exposure resulted in Trx1 downregulation and increased ASK1/p38 MAPK phosphorylation, which could be reversed by NACA and NAC. To our knowledge, this is the first report that Trx1 and ASK1 are involved in CIN. Our study highlights a renal protective role of NACA against CIN through modulating Trx1 and ASK1/p38 MAPK pathway to result in the inhibition of apoptosis among renal cells. PMID:28105252

    Full Text Available International Society of Blood Transfusion has recently recognized 33 blood group systems. Apart from ABO and Rhesus system, many other types of antigens have been noticed on the red cell membranes. Blood grouping and cross-matching is one of the few important tests that the anaesthesiologist orders during perioperative period. Hence, a proper understanding of the blood group system, their clinical significance, typing and cross-matching tests, and current perspective are of paramount importance to prevent transfusion-related complications. Nonetheless, the knowledge on blood group system is necessary to approach blood group-linked diseases which are still at the stage of research. This review addresses all these aspects of the blood groups system.

    2001-07-01

    The issue of nuclear power is one of themes that tend to produce severe confrontation over pros and cons of its utilization. The logic of the groups promoting nuclear energy utilization contains the conception which approves people's needs to energy and the paternalism that policy-making is to be in the hands of experts of specialized knowledge and ripe experiences. Behind the opinion of anti-nuclear groups of citizen movement style there are criticisms to the centralization of power and the technocracy, and they regard nuclear power as a symbol of the modern social system. On the other hand, the general publics who are put out of the decision-making process on nuclear power development are increasing the sense of powerless and apathy on the nuclear power issue, and their attitude of free ride on energy utilization is becoming predominant. The true targets to which both proponent and opponent groups should intervene seriously are free riders and the mechanism of the society structuring such situation. If both parties become deeply aware of the problems common to them and have intension of solving the problems, the scheme of the present conflict may change into that of complementary division of work.

    Full Text Available In his long address called “Why Lausanne?” Dr Billy Graham clearly stated the reason and purpose to have the International Congress on World Evangelization by saying that “we are met to pray, talk, plan and to advance the work of evangelism ,” and he adds: “This is a conference of evangelicals. The participants were asked to come because you are evangelical-concerned with evangelism and missions; and we here tonight stand firmly in the evangelical tradition of Biblical faith.” Here we can find two specific reasons for the congress: to discuss for furtherance of world evangelism and to bring evangelicals together for a united front of the world evangelization. For this purpose the invitations were sent to all over the world. According to statistics published officially by the congress six continents sent their representatives to the congress responding to the invitation though it was sent on individual basis: 458 from Africa, 729 from Asia, 1 115 from North and Central America, 777 from Europe, 180 from South America and 150 from Oceania. Literally it was a world-wide congress. There was never such a large gathering before on a single purpose.

    Objective To evaluate the potential relationship between isoforms of BRCA1 associated RING domain 1 ( BARD1 ) and the pathophysiologic markers of sporadic breast carcinoma of female Han ethnic group. Methods The expression of BARD1 isoforms in 39 breast carcinomatous tissue, 12paracancerous-normal breast tissue and 7 controlled normal breast tissue was detected by reverse transcription polymerase chain reaction (RT-PCR) and then cloned and sequenced.The difference of isoforms expression and their clinical significance were analyzed. Results There were four transcriptive products of BARD1 found in all these candidates,named full lenth,isoform γ,isoform δ and isoform e.The positive rate of isoform γ and δ was higher in carcinomatous tissues than in paracancerous-normal tissues and normal breast tissue in healthy women ( P < 0.05 ). Carcinomatous tissue expressed more kinds of isoforms.There was significant difference between carcinomatous tissue and paranormal/nomal tissue ( P =0.0075 ).There was significant correlation between isoform ε positive and poor prognosis factors such as poorly differentiation,HER2 positive,poor pathologic type and larger breast cancer lumps(P < 0.05 ). Conclusions There are significant differences in the expression of BARD1 isoforms among different kinds breast tissues in the female Han ethnic group.Positive isoform ε may predict poor prognosis of breast carcinoma in the female Han ethnic group.%目的 探讨乳腺癌基因1相关环指结构域蛋白1 (BRCA1 associated RING domain 1,BARD1)剪切变异体在乳腺癌组织中的表达及其临床意义.方法 对北京医院乳腺中心液氮冷冻储存的39例汉族女性散发性乳腺癌组织、12例癌旁乳腺组织和7例正常汉族女性乳腺组织提取目的基因,检测BARD1剪切变异体在不同组织中的表达状况,分析剪切变异体在不同组织中表达的差异及其临床意义.结果 在各种组织中共发现4种BARD1基因的转录产物,分别

    2012-04-01

    The National Cancer Institute (NCI)-funded cooperative group cancer clinical trial system develops experimental therapies and often collects samples from patients for correlative research. The cooperative group bank (CGB) system maintains biobanks with a current policy not to return research results to individuals. An online survey was created, and 10 directors of CGBs completed the surveys asking about understanding and attitudes in changing policies to consider return of incidental findings (IFs) and individual research results (IRRs) of health significance. The potential impact of the 10 consensus recommendations of Wolf et al. presented in this issue are examined. Reidentification of samples is often not problematic; however, changes to the current banking and clinical trial systems would require significant effort to fulfill an obligation of recontact of subjects. Additional resources, as well as a national advisory board would be required to standardize implementation.

    Full Text Available This study aimed to verify two hypotheses of the text questionability theory (Virbel: 1 the recall is similar to the author's question-asking organization; and 2 the similarity between the recall and the questionability force will be in function of the text consistency. A first experiment compared the recall of 53 subjects with the questionability force of the elementary sentences. Significant correlations and regressions between the two variables were found. A second experiment analyzed the recall of 141 subjects in 2 versions of the story of the first experiment differentiated by the degree of consistency Correlations were found only in the version with higher degree of consistency. The results of the 2 experiments were in accordance with the questionability theory in that, in order to understand and to reconstruct a story, the 'comprehender' follows a hierarchical network, which organizes the unities of meaning based on their questionability force.

  16. "I Wouldn't Have Asked for Help if I had to go to the Library": Reference Services On Site

    OpenAIRE

    Lee, Jennifer; Hayden, K. Alix; MacMillan, Don

    2004-01-01

    Students may be reluctant to ask questions at a library reference desk because it is such a public venue. It may be possible to give them an alternative by providing reference services outside of the library within a faculty lab or office. Advantages include convenience and proximity to students, faculty, and their learning communities. The service may also foster closer and stronger relationships with departments. It is important to choose a location wisely, as well as advertise widely. This...

  19. Science Learning: A path analysis of its links with reading comprehension, question-asking in class and science achievement

    2014-07-01

    The purpose of this research was to build and test a conceptual model of the complex interrelationships between students' learning in science (learning approaches and self-regulation), their reading comprehension, question-asking in class and science achievement. These variables were measured by means of a test and a series of questionnaires administered to 604 ninth-grade students, and the data collected were analysed using a correlational, cross-sectional design. Results of a path analysis indicated that (a) students' self-regulated and intentional knowledge-constructing activity (self-regulated strategy use, deep approach and knowledge-building) were what chiefly accounted for their question-asking in class; (b) question-asking (high and low levels) was related directly to reading comprehension and indirectly, through its contribution to the this, to academic achievement; (c) reading comprehension was directly and negatively associated with surface approach and indirectly and positively related to deep approach and knowledge-building; and (d) some of these variables, particularly reading comprehension, accounted for academic achievement in science. This model explained nearly 30% of the variance in academic achievement and provided a substantial and distinctive insight into the web of interrelationships among these variables. Implications for future research and science teaching and learning are discussed (e.g. the importance of supporting students' efforts to learn science in a meaningful, active and self-regulated way and of improving their reading comprehension).

  20. Oxytocin enhances implicit social conformity to both in-group and out-group opinions.

    People often alter their own preferences when facing conflicting opinions expressed by others. This is known as the social conformity effect and tends to be stronger in response to opinions expressed by in-group relative to out-group members. The hypothalamic neuropeptide oxytocin promotes in-group favoritism, elicits parochial altruism, and stimulates in-group conformity under explicit social pressure. In a double-blind, placebo-controlled design experiment using a facial attractiveness judgment task, we therefore investigated whether social conformity to either in-group or out-group opinions is influenced by intranasal oxytocin treatment when social pressure is implicit. After oxytocin or placebo treatment, male participants were asked to rate the attractiveness of unfamiliar Chinese female faces, and then they were informed of ratings given by peers from an in-group (Chinese) and out-group (Japanese) simultaneously. They were subsequently asked unexpectedly to re-rate the same faces. Results showed that oxytocin increased conformity to both in- and out-group opinions. Thus oxytocin promotes conformity to opinions of both in- and out-group members when social pressure is implicit, suggesting that it facilitates 'tend and befriend' behaviors by increasing the general level of social conformity.

    2016-04-01

    It is widely recognised that developmentally appropriate services for adolescents and young people improve both healthcare experience and health outcomes. However, there is limited evidence of using young people's expertise to evaluate services, or of young people participating in service developments or design to meet their healthcare needs. This report covers both the process and outcomes of a collaborative project with a group of young people (aged 17-25 years) who are 'experts by experience'. We used qualitative mixed methodology to derive themes from narrative accounts of these young people's healthcare experiences to develop an assessment framework that they identified as being relevant to evaluating services. Informing young people about other assessment measures currently in use (including the Department of Health's You're Welcome quality criteria) enabled the group to further develop their views and refine their proposed assessment framework. This paper is co-authored with young people, enabling them to directly voice their views about healthcare services. Reflections on this process and recommendations for working more collaboratively with young people to evaluate healthcare services are also given.

  2. Cohesion group approach for evolutionary analysis of aspartokinase, an enzyme that feeds a branched network of many biochemical pathways.

    Aspartokinase (Ask) exists within a variable network that supports the synthesis of 9 amino acids and a number of other important metabolites. Lysine, isoleucine, aromatic amino acids, and dipicolinate may arise from the ASK network or from alternative pathways. Ask proteins were subjected to cohesion group analysis, a methodology that sorts a given protein assemblage into groups in which evolutionary continuity is assured. Two subhomology divisions, ASK(alpha) and ASK(beta), have been recognized. The ASK(alpha) subhomology division is the most ancient, being widely distributed throughout the Archaea and Eukarya and in some Bacteria. Within an indel region of about 75 amino acids near the N terminus, ASK(beta) sequences differ from ASK(alpha) sequences by the possession of a proposed ancient deletion. ASK(beta) sequences are present in most Bacteria and usually exhibit an in-frame internal translational start site that can generate a small Ask subunit that is identical to the C-terminal portion of the larger subunit of a heterodimeric unit. Particularly novel are ask genes embedded in gene contexts that imply specialization for ectoine (osmotic agent) or aromatic amino acids. The cohesion group approach is well suited for the easy recognition of relatively recent lateral gene transfer (LGT) events, and many examples of these are described. Given the current density of genome representation for Proteobacteria, it is possible to reconstruct more ancient landmark LGT events. Thus, a plausible scenario in which the three well-studied and iconic Ask homologs of Escherichia coli are not within the vertical genealogy of Gammaproteobacteria, but rather originated via LGT from a Bacteroidetes donor, is supported.

  3. Product-free subsets of profinite groups

    2012-01-01

    Gowers in his paper on quasirandom groups studies a question of Babai and Sos asking whether there exists a constant $c > 0$ such that every finite group $G$ has a product-free subset of size at least $c|G|$. Answering the question negatively, he proves that for sufficiently large prime $p$, the group $\\mathrm{PSL}_2(\\mathbb{F}_p)$ has no product-free subset of size $cn^{8/9}$, where $n$ is the order of $\\mathrm{PSL}_2(\\mathbb{F}_p)$. We will consider the problem for compact groups and in particular for profinite groups $\\SL_k(\\ZZ_p)$ obtain lower and upper exponential bounds for the supremal measure of the product-free sets. The proof involves establishing a lower bound for the dimension of non-trivial representations of the finite groups $\\SL_k(\\Z{p^n})$.

    The aim was to examine gender differences in sexual risk communication among young couples and factors influencing communication. Sample consisted of 296 young pregnant couples. We assessed individual, interpersonal, and community factors on sexual risk communication. The Actor-Partner Independence Model was used to assess actor and partner effects on sexual risk communication. For actor effects, being female, older, not being Hispanic, and higher condom use self-efficacy was associated with sexual risk communication. The significant partner effect was avoidant romantic attachment. Gender interactions were significant for high risk behaviors and family functioning. High risk behaviors and family functioning were associated with sexual risk communication for females but not for males. The study emphasizes the need to promote sexual risk communication among young high risk couples, particularly for males. Family support could serve as a catalyst for sexual risk communication and other sexual protective behaviors among young couples.

    Full Text Available Questioning techniques have historically been considered the measurement by which teachers challenge and gauge student learning. Much has been said about questioning strategies used by teachers; yet little is known about the strategies used by pre-service teachers, especially those that are working with English language learners. This study presents findings from a qualitative study that explored what types of questions pre-service teachers use and their reflections on the use of such strategies. Eight bilingual/ESL pre-service teachers in South Texas were videotaped during a math and a language arts lesson, attended focus groups, and participated in an exit interview. The findings revealed the type of questions used by the participants, how they made sense of their teaching, and how accountability measures influenced their teaching. This research recommends education programs to prepare future teachers to comply with what is required by the current reform without compromising their students’ learning and thinking skills.

    Full Text Available It is well acknowledged that innovation is a key success factor in the mobile service domain. Having creative ideas is the first critical step in the innovation process. Many studies suggest that customers are a valuable source of creative ideas. However, the literature also shows that adults may be constrained by existing technology frames, which are known to hinder creativity. Instead young children (aged 7-12 are considered digital natives yet are free from existing technology frames. This led us to study them as a potential source for creative mobile service ideas. A set of 41,000 mobile ideas obtained from a research project in 2006 granted us a unique opportunity to study the mobile service ideas from young children. We randomly selected two samples of ideas (N = 400 each; one contained the ideas from young children, the other from adults (aged 17-50. These ideas were evaluated by several evaluators using an existing creativity framework. The results show that the mobile service ideas from the young children are significantly more original, transformational, implementable, and relevant than those from the adults. Therefore, this study shows that young children are better sources of novel and quality ideas than adults in the mobile services domain. This study bears significant contributions to the creativity and innovation research. It also indicates a new and valuable source for the companies that seek creative ideas for innovative products and services.

  10. Measuring Library Vendor Cyber Security: Seven Easy Questions Every Librarian Can Ask

    2016-04-01

    Full Text Available This article is based on an independent cyber security risk management audit for a public library system completed by the authors in early 2015 and based on a research paper by the same group at Clark University in 2014. We stress that while cyber security must include raising public knowledge in regard to cyber security issues and resources, and libraries are indeed the perfect place to disseminate this knowledge, librarians are also in a unique position as the gatekeepers of information services provided to the public and should conduct internal audits to ensure our content partners and IT vendors take cyber security as seriously as the library and its staff. One way to do this is through periodic reviews of existing vendor relationships. To this end, the authors created a simple grading rubric you can adopt or modify to help take this first step towards securing your library data. It is intended to be used by both technical and non-technical staff as a simple measurement of what vendor agreements currently exist and how they rank, while at the same time providing a roadmap for which security features or policy statements the library can or should require moving forward.

  11. Assessing preferences about the DNR order: does it depend on how you ask?

    Percy, M E; Llewellyn-Thomas, H

    1995-01-01

    Despite increasing emphasis on advance directives, there has been little methodologic work to assess preferences about the "do not resuscitate" (DNR) order. This developmental work assessed, in a non-patient group, the performance of a probability-trade-off task designed to assess DNR attitudes, in terms of framing effects and stability of preferences. 105 female nursing students each completed one of two versions of the task. In version I (n = 58), the trade-off moved to increasingly negative descriptions of the outcomes of resuscitation (decreasing chance of survival and increasing risk of brain death), whereas in version II (n = 47), the trade-off moved to increasingly positive descriptions. One week later, repeat assessments were obtained for versions I (n = 35) and II (n = 28). The DNR preference scores were lower and more stable when the task moved to increasingly positive descriptions; perhaps this version of the task tends to weaken risk aversion. These results imply that care should be used in applying a probability trade-off task to the assessment of DNR preferences, since artefactual effects could be induced.

    2011-10-01

    Vaccination against the types of human papillomavirus (HPV) that cause about 70% of cervical cancers is approved for use in girls and women between 9 and 26 years of age and recommended routinely in 11-12-year-old girls. This article reports on the systematic theory-based formative research conducted to develop HPV vaccine messages for a campaign targeting racially diverse mothers of nonvaccinated 11-12-year-old girls in rural Southeastern United States. A consortium of 13 county health departments concerned about high rates of cervical cancer in their region relative to state and national averages initiated the campaign. The research examined behavioral determinants for vaccination decisions as well as mothers' reactions to message frames and emotional appeals. On the basis of focus groups and intercept interviews (n = 79), the authors demonstrated how preproduction message research and production message testing were used to develop messages that would motivate mothers of preteen girls. Core emotional truths that emerged were a mother's instinct to protect her daughter from harm and to embrace aspirations for her daughter's future. Mothers also reacted more positively to text about preventing cervical cancer than about preventing HPV, a sexually transmitted disease. Mothers preferred message concepts with photos of minorities and Caucasian mothers and daughters.

    Self-reflection in multicultural education is an important means to develop self-awareness and ultimately to change professional behavior in favor of more equitable health care to diverse populations. As conceptualized by scholars in the field of psychology, racial identity theory is critical to understanding and planning for the potentially wide range of predictable reactions to provocative activities, including those negative reactions that do not necessarily herald a flaw in programming. Careful consideration of racial identity developmental phases can also assist program planners to optimally meet the needs of individual physician trainees in their ongoing constructive professional and personal development, and in strategically mobilizing and having ready the type of institutional leadership that supports trainees' change processes. The authors focus on white physician trainees, the largest racial group of U.S. physicians and medical students. They first explain what they mean by the terms white and nonwhite. Racial identity theory is then applied, with true case examples, to explore such issues as where the self-proclaimed "color-blind" trainee fits into this theoretical schema, and how medical educators can best serve trainees who are resistant or indifferent to discussions of racism in medicine and equity in health care delivery. Ultimately, the authors' goal is to demonstrate that engendering genuine self-reflection can substantively improve the delivery of health care to the nation's diverse population. To help achieve that goal, they emphasize what to anticipate in effecting optimal trainee education and how to create an institutional climate supportive of individual change.

    2005-06-01

    Statistically significant differences between treatments (i.e., results typically associated with p influences the perception of importance of study results were true, we would expect that presenting such a p-value would lead to 1) greater agreement among clinicians about the importance of a study result, and 2) greater perceived importance of a study result, when compared with presenting the same results omitting the p-value. The participants were 3 orthopedics residents, 5 fellows, and 4 attending orthopedic surgeons at a university hospital. We constructed a 40-item questionnaire with the comparison groups, primary outcome of interest, and the results from each of 40 studies. These studies represent a variety of interventions across orthopedic surgery assessed in 2-group comparative intervention studies (randomized trials, observational studies) and were published between 2000 and 2002 in the Journal of Bone and Joint Surgery--American Volume. For each question, respondents were asked to rate the importance of the study results. Participants answered the questionnaire first without p-values and then, 8 weeks later, with p-values (and a random sample of items without p-values). An intra-class correlation quantified agreement between clinicians when answering items with and without p-values. The difference in mean importance scores between the two presentations was also estimated. Of 40 eligible clinical comparative studies, 30 reported p influence the perception of clinicians regarding the importance of study results.

  15. The link between couples' pregnancy intentions and behavior: does it matter who is asked?

    Waller, Maureen R; Bitler, Marianne P

    2008-12-01

    Previous studies have linked pregnancy intentions with some pregnancy-related behaviors and infant health outcomes. However, most have used only women's reports of intentions and examined only maternal behaviors. Baseline data from the Fragile Families and Child Wellbeing Study (1998-2000) are used to examine whether parents of newborns considered abortion upon learning of the pregnancy and whether this measure of pregnancy intention is associated with their behaviors during pregnancy or with infant birth weight. Associations between outcomes and each parent's pregnancy intention are explored with multivariate probit regressions or least squares regressions for 737 married and 2,366 unmarried couples. If at least one parent considered abortion, unmarried mothers had a significantly reduced probability of initiating early prenatal care, and unmarried fathers had a significantly reduced probability of providing cash or in-kind support during the pregnancy. The proportion of mothers receiving care in the first trimester was 12 percentage points lower when the mother only or both parents considered abortion than when neither parent did; depending on which parent reported on fathers' support during pregnancy, the proportion of fathers who provided cash or in-kind assistance was 6-10 percentage points lower when the father only considered abortion and 6-14 points lower when both parents considered abortion than when neither did. Future research on pregnancy intentions should incorporate both men and women. Understanding men's pregnancy intentions and their associations with early support of mothers may inform discussions of how to encourage men's involvement in family planning, prenatal health care and parenting.

    Full Text Available Background: This paper introduces a tool for streamlining data integration in rehabilitation science, the Centralized Open-Access Rehabilitation database for Stroke (SCOAR, which allows researchers to quickly visualize relationships among variables, efficiently share data, generate hypotheses, and enhance clinical trial design. Methods: Bibliographic databases were searched according to inclusion criteria leaving 2,892 titles that were further screened to 514 manuscripts to be screened by full text, leaving 215 randomized controlled trials in the database (489 independent groups representing 12,847 patients. Demographic, methodological, and statistical data were extracted by independent coders and entered into SCOAR. Results: Trial data came from 114 locations in 27 different countries and represented patients with a wide range of ages, 62 yr 41; 85, (shown as median range and at various stages of recovery following their stroke, 141 d 1; 3372. There was considerable variation in the dose of therapy that patients received, 20 h 0; 221, over interventions of different durations, 28 d 10; 365. There was also a lack of common data elements (CDEs across trials, but this lack of CDEs was most pronounced for baseline assessments of patient impairment and severity of stroke. Conclusions: Data integration across hundreds of RCTs allows clinicians and researchers to quickly visualize data from the history of the field and lays the foundation for making SCOAR a living database to which researchers can upload new data as trial results are published. SCOAR is a useful tool for clinicians and researchers that will facilitate data visualization, data sharing, the finding of relevant past studies, and the design of clinical trials by enabling more accurate and comprehensive power analyses. Furthermore, these data speak to the need for CDEs specific to stroke rehabilitation in randomized controlled trials.PROSPERO# CRD4201409010

    Tumor necrosis factor-α (TNF-α) is a pro-inflammatory cytokine produced by monocytes/macrophage that plays a pathological role in rheumatoid arthritis (RA). In this study, we investigate the effect of thymoquinone (TQ), a phytochemical found in Nigella sativa, in regulating TNF-α-induced RA synovial fibroblast (RA-FLS) activation. Treatment with TQ (1-5μM) had no marked effect on the viability of human RA-FLS. Pre-treatment of TQ inhibited TNF-α-induced interleukin-6 (IL-6) and IL-8 production and ICAM-1, VCAM-1, and cadherin-11 (Cad-11) expression in RA-FLS (pinhibited TNF-α-induced phospho-p38 and phospho-JNK expression, but had no inhibitory effect on NF-κB pathway, in RA-FLS (pTNF-α-induced phospho-p38 and phospho-JNK activation by TQ is elicited through inhibition of apoptosis-regulated signaling kinase 1 (ASK1). Furthermore, TNF-α selectively induced phosphorylation of ASK1 at Thr845 residue in RA-FLS, which was inhibited by TQ pretreatment in a dose dependent manner (pTNF-α induced expression of ICAM-1, VCAM-1, and Cad-11. Our results suggest that TNF-α-induced ASK1-p38/JNK pathway is an important mediator of cytokine synthesis and enhanced expression of adhesion molecule in RA-FLS and TQ, by selectively inhibiting this pathway, may have a potential therapeutic value in regulating tissue destruction observed in RA.

  18. What should vaccine developers ask? Simulation of the effectiveness of malaria vaccines.

    Directory of Open Access Journals (Sweden)

    Melissa A Penny

    Full Text Available BACKGROUND: A number of different malaria vaccine candidates are currently in pre-clinical or clinical development. Even though they vary greatly in their characteristics, it is unlikely that any of them will provide long-lasting sterilizing immunity against the malaria parasite. There is great uncertainty about what the minimal vaccine profile should be before registration is worthwhile; how to allocate resources between different candidates with different profiles; which candidates to consider combining; and what deployment strategies to consider. METHODS AND FINDINGS: We use previously published stochastic simulation models, calibrated against extensive epidemiological data, to make quantitative predictions of the population effects of malaria vaccines on malaria transmission, morbidity and mortality. The models are fitted and simulations obtained via volunteer computing. We consider a range of endemic malaria settings with deployment of vaccines via the Expanded program on immunization (EPI, with and without additional booster doses, and also via 5-yearly mass campaigns for a range of coverages. The simulation scenarios account for the dynamic effects of natural and vaccine induced immunity, for treatment of clinical episodes, and for births, ageing and deaths in the cohort. Simulated pre-erythrocytic vaccines have greatest benefits in low endemic settings (EIR of 84 PEV may lead to increased incidence of severe disease in the long term, if efficacy is moderate to low (20% malaria vaccines (either PEV or BSV when deployed through mass campaigns targeting all age-groups as well as EPI, and especially if combined with highly efficacious transmission-blocking components. CONCLUSIONS: We present for the first time a stochastic simulation approach to compare likely effects on morbidity, mortality and transmission of a range of malaria vaccines and vaccine combinations in realistic epidemiological and health systems settings. The results raise

  19. Abortion foes get turn to ask Supreme Court for constitutional protection.

    1994-04-28

    The US Supreme Court began hearing arguments on the constitutionality of a Florida judge's order which placed limits on anti-abortion protesting. This case will be the last abortion--related decision for Justice Harry A. Blackmun, who was the author of the original decision granting the right to abortion in Roe vs. Wade, before retiring from the Court in September 1994. Anti-abortion activists claim 1st Amendment protection, much the same as Dr. Martin Luther King's marches in advancing Blacks' civil rights. The case involved a Melbourne abortion clinic. The murder of Dr. Gunn outside an abortion clinic in Pensacola, Florida, will be used to support the need for protection from extremist violence. The conflict appears to be over the right to save women's right to abortion and over simple, peaceful protests and prayers against abortion. One anti-abortion foe, affiliated with Operational Rescue and initiating the appeal to the Supreme Court, is scheduled to testify before the Court: Judy Madsen, a protester who has counseled outside clinics. Ms. Madsen says she is exercising her freedom to protect human life. Other testimony will come from Reverend Ed Martin of Ocala, Rescue America's founder, and Shirley Hobbs, a homemaker from Orlando. Representation will be made by lawyer Matthew Staver, who will argue that the ruling was directed to a political position. Other support will come from religious and anti-abortion groups and the AFL-CIO. Testifying for the clinic, the Aware Women's Center for Choice, will be the owner and operator Patricia Baird Windle. Over the past 5 years, the Melbourne Clinic had been a target for the nationwide anti-abortion campaign by Operation Rescue. Because of the conflicting rulings between the Florida Supreme Court, which ruled to keep protesters away from clinic grounds and staff homes, and 11th US Circuit Court of Appeals ruling of unconstitutionality, no protection is afforded the clinic. Previous protection had occurred due to a 1992

    Full Text Available Normal 0 false false false EN-US JA X-NONE This article reflects upon the research methods employed for microfemininewarfare (2012, an interactive database documentary that investigates female electronic dance music (EDM artists. The purpose of the documentary is to feature the contributions of women as composers, to show how they came to be composers and to reveal the tactics used to approach significant issues of gender in the male-dominated world of EDM. I highlight the theoretical and methodological processes that went into the making of this documentary, subtitled “exploring women’s space in electronic music”. By constructing “electronic music by women” as a category, two objectives are addressed: first, the visibility of women’s contribution to the musical tradition is heightened; and, second, it allows an exploration of the broadening of discourses about female subjectivity. This article showcases feminist research-creation and friendship-as-method as effective research methods to glean meaningful content when applied to EDM fieldwork.

When I started this project, it was not my objective to develop a model for any specific disease, nor did I even suspect that the ultimate result would be some insight into autoimmune disease. The basic research question I was asking was why there are sequences in the 3′ untranslated region (3′UTR) of the interferon-gamma (IFN-gamma) mRNA that are more highly conserved than in the coding region of the gene.

    Full Text Available Traditional Chinese medicine (TCM; 中醫 zhōng yī syndrome groups are based on the symptoms of human diseases and guide the use of Chinese herbs. The aim of this study was to examine the effects of TCM syndrome groups on biochemical characteristics and quality of life (QOL in women with metabolic syndrome (MS. Among the 1080 registered female patients screened at our outpatient clinic, a total of 322 women aged between 18 and 65 years and meeting the requirements of MS were enrolled. All the patients were asked to fill out a questionnaire on metabolic TCM syndrome groups and a questionnaire on the QOL, the Medical Outcomes Study (MOS Short Form-12 (SF-12. Data of biochemical characteristics were collected at the same time. The present study showed MS women in TCM syndrome groups had significantly lower physical and mental component scores in SF-12 compared with those not in TCM syndrome groups. We also found MS patients in TCM syndrome groups, except Kidney Deficiency syndrome, showed higher body mass indexes, waist circumference, and hip circumference. However, there was almost no difference in most biochemical characteristics between TCM syndrome groups. The MS patients diagnosed as belonging to TCM syndrome groups had poor QOL.

    Full Text Available Abstract The exponential development of Patient-Reported Outcomes (PRO measures in clinical research has led to the creation of the Patient-Reported Outcome and Quality of Life Instruments Database (PROQOLID to facilitate the selection process of PRO measures in clinical research. The project was initiated by Mapi Research Trust in Lyon, France. Initially called QOLID (Quality of Life Instruments Database, the project's purpose was to provide all those involved in health care evaluation with a comprehensive and unique source of information on PRO and HRQOL measures available through the Internet. PROQOLID currently describes more than 470 PRO instruments in a structured format. It is available in two levels, non-subscribers and subscribers, at http://www.proqolid.org. The first level is free of charge and contains 14 categories of basic useful information on the instruments (e.g. author, objective, original language, list of existing translations, etc.. The second level provides significantly more information about the instruments. It includes review copies of over 350 original instruments, 120 user manuals and 350 translations. Most are available in PDF format. This level is only accessible to annual subscribers. PROQOLID is updated in close collaboration with the instruments' authors on a regular basis. Fifty or more new instruments are added to the database annually. Today, all of the major pharmaceutical companies, prestigious institutions (such as the FDA, the NIH's National Cancer Institute, the U.S. Veterans Administration, dozens of universities, public institutions and researchers subscribe to PROQOLID on a yearly basis.

    Security has always been a popular and critical topic. With the rapid development of information technology, it is always attracting people’s attention. However, since security has a long history, it covers a wide range of topics which change a lot, from classic cryptography to recently popular mobile security. There is a need to investigate security-related topics and trends, which can be a guide for security researchers, security educators and security practitioners. To address the above-mentioned need, in this paper, we conduct a large-scale study on security-related questions on Stack Overflow. Stack Overflow is a popular on-line question and answer site for software developers to communicate, collaborate, and share information with one another. There are many different topics among the numerous questions posted on Stack Overflow and security-related questions occupy a large proportion and have an important and significant position. We first use two heuristics to extract from the dataset the questions that are related to security based on the tags of the posts. And then we use an advanced topic model, Latent Dirichlet Allocation (LDA) tuned using Genetic Algorithm (GA), to cluster different security-related questions based on their texts. After obtaining the different topics of security-related questions, we use their metadata to make various analyses. We summarize all the topics into five main categories, and investigate the popularity and difficulty of different topics as well. Based on the results of our study, we conclude several implications for researchers, educators and practitioners.

  11. [Implicit personality theories in dermatology. An empirical study on the image that physicians have of patients of diverse dermatologic diagnosis groups].

    Studies about the personality of dermatological patients are numerous. The results are inconsistent and peculiarities of the personality are rarely confirmed. Contrary to the usual procedure, this study asks for the impressions physicians have about their patients. To elicit associations dependent on a dermatological diagnosis, 27 physicians filled in a three-dimensional differential asking for their impressions about patients with atopic dermatitis, leg ulcer, malignant melanoma, or psoriasis vulgaris in order to quantify these impressions. The dimension valence (good-bad) did not differ between the groups. The dimensions of excitation (active-passive) and potency (strong-weak) showed the biggest differences between patients with atopic dermatitis and ulcus cruris. The latter get significantly lower values on both dimensions. The correlations between the impression and the duration of employment in dermatology were low. In our opinion it is necessary to raise the impression of medical personal about their patients because these impressions affect the interaction of the personal with the patient.

  12. Significance Tests for Periodogram Peaks

    2007-01-01

    We discuss methods currently in use for determining the significance of peaks in the periodograms of time series. We discuss some general methods for constructing significance tests, false alarm probability functions, and the role played in these by independent random variables and by empirical and theoretical cumulative distribution functions. We also discuss the concept of "independent frequencies" in periodogram analysis. We propose a practical method for estimating the significance of periodogram peaks, applicable to all time series irrespective of the spacing of the data. This method, based on Monte Carlo simulations, produces significance tests that are tailor-made for any given astronomical time series.

    In this paper we show a new method of using automatic age and gender recognition to recommend a sequence of multimedia items to a home TV audience comprising multiple viewers. Instead of relying on explicitly provided demographic data for each user, we define an audio-based demographic group......, which itself is the input to a recommender system. The recommender system finds the content items whose demographics best match the group profile. We tested the effectiveness of the system for several typical home audience configurations. In a survey, users were given a configuration and asked to rate...... a set of advertisements on how well each advertisement matched the configuration. Unbeknown to the subjects, half of the adverts were recommended using the derived audio demographics and the other half were randomly chosen. The recommended adverts received a significantly higher median rating of 7...

  14. Significant Scales in Community Structure

    Traag, V A; Van Dooren, P

    2013-01-01

    Many complex networks show signs of modular structure, uncovered by community detection. Although many methods succeed in revealing various partitions, it remains difficult to detect at what scale some partition is significant. This problem shows foremost in multi-resolution methods. We here introduce an efficient method for scanning for resolutions in one such method. Additionally, we introduce the notion of "significance" of a partition, based on subgraph probabilities. Significance is independent of the exact method used, so could also be applied in other methods, and can be interpreted as the gain in encoding a graph by making use of a partition. Using significance, we can determine "good" resolution parameters, which we demonstrate on benchmark networks. Moreover, optimizing significance itself also shows excellent performance. We demonstrate our method on voting data from the European Parliament. Our analysis suggests the European Parliament has become increasingly ideologically divided and that nationa...

    Full Text Available This essay outlines a recent assignment I designed for an upper-division cross-listed women and gender studies/social justice and human rights course I teach called, “Trash, Freaks, and SCUM.”  In the context of the students reading Edward Humes’ (2012 Garbology, the trash bag assignment asked that students carry around their trash for two 48-hour periods and that they present it to the class.  While the first two day period assesses their actual trash output, students are asked to produce as little trash as possible for the second two day period. This assignment aims to make trash visible and to help students learn about climate change, sustainability, conspicuous consumption, and how their individual carbon footprint contributes to the “big picture” of environmental strain.  I describe this assignment and its goals in this essay, followed by an assessment of its role in teaching about social justice, in order to underscore the importance of experiential learning with trash and to highlight how this assignment fits the mission of my courses on feminism and social justice.

    Full Text Available Several studies have analysed liquidity across a trading day, and have documented that bid-ask spreads exhibita U-shaped pattern, with spreads wider at the start and end of the trading day, whilst spreads are tighter in themiddle of the day. This pattern has been attributed to inventory holding costs, the specialist’s market powerand adverse selection risk. On the 2nd April, 2001, several stocks on the Italian Bourse switched from anauction market to a specialist market. This provides a natural experiment where intraday spreads acrossdifferent market structures can be compared. Results indicate that volume, volatility and bid-ask spreadsexhibit the U-shaped intraday pattern both before and after the structural change. While time-weightedspreads are consistently higher throughout the trading day under the specialist structure, the specialists abilityto offer price improvement with the best quotes results in the ‘real’ cost of trading being lower under aspecialist system. These results are robust to the size of the firm, the event window around the structuralchange, as well as overall market-wide changes.

    Estimating effectiveness of clinical interventions depends on detecting differences between the responses of intervention and control groups. The outcome, intervention, and moderating factors all may influence the between group change. The absence of a clinically or statistically meaningful difference may also result from control group improvement due to nonspecific factors such as participants' perception of attention, positive regard, expectations, desire to please, and therapeutic alliance with the care provider. We examined perceived benefit and sources of benefit for control caregivers who participated in the CONNECT randomized controlled trial of a dementia caregiving intervention. After the final scheduled data collection in CONNECT, control group participants were asked whether they believed they benefited from study participation. Those who reported benefit were asked to describe the benefit received. Data were analyzed qualitatively. Of 60 available control caregivers, 82% reported a perceived benefit from study participation in five areas: getting information about dementia and caregiving; having someone to talk to and feeling supported; receiving understanding and validation of feelings; knowledge that others were in similar situations; and perceived appreciation of own abilities. Control caregivers who reported benefit were less burdened and depressed and spent less time on duty at baseline than those who did not report benefit. From caregivers' responses, we have identified the assessment battery, both content and time spent in data collection, as a possible mechanism of action for benefit. Study limitations include the better baseline characteristics of the control caregivers who reported benefit, the sample size of benefit control caregivers, the possibility of perceptions of benefit being a function of social desirability, and the lack of a similar question about benefit being asked of intervention caregivers. These findings suggest that the
