    Full Text Available Abstract Background Within Chlorophyceae the ITS2 secondary structure shows an unbranched helix I, except for the 'Hydrodictyon' and the 'Scenedesmus' clade having a ramified first helix. The latter two are classified within the Sphaeropleales, characterised by directly opposed basal bodies in their flagellar apparatuses (DO-group. Previous studies could not resolve the taxonomic position of the 'Sphaeroplea' clade within the Chlorophyceae without ambiguity and two pivotal questions remain open: (1 Is the DO-group monophyletic and (2 is a branched helix I an apomorphic feature of the DO-group? In the present study we analysed the secondary structure of three newly obtained ITS2 sequences classified within the 'Sphaeroplea' clade and resolved sphaeroplealean relationships by applying different phylogenetic approaches based on a combined sequence-structure alignment. Results The newly obtained ITS2 sequences of Ankyra judayi, Atractomorpha porcata and Sphaeroplea annulina of the 'Sphaeroplea' clade do not show any branching in the secondary structure of their helix I. All applied phylogenetic methods highly support the 'Sphaeroplea' clade as a sister group to the 'core Sphaeropleales'. Thus, the DO-group is monophyletic. Furthermore, based on characteristics in the sequence-structure alignment one is able to distinguish distinct lineages within the green algae. Conclusion In green algae, a branched helix I in the secondary structure of the ITS2 evolves past the 'Sphaeroplea' clade. A branched helix I is an apomorph characteristic within the monophyletic DO-group. Our results corroborate the fundamental relevance of including the secondary structure in sequence analysis and phylogenetics.

    Full Text Available Background Comparative studies of chloroplast genomes (plastomes across the Chlorophyceae are revealing dynamic patterns of size variation, gene content, and genome rearrangements. Phylogenomic analyses are improving resolution of relationships, and uncovering novel lineages as new plastomes continue to be characterized. To gain further insight into the evolution of the chlorophyte plastome and increase the number of representative plastomes for the Sphaeropleales, this study presents two fully sequenced plastomes from the green algal family Hydrodictyaceae (Sphaeropleales, Chlorophyceae, one from Hydrodictyon reticulatum and the other from Pediastrum duplex. Methods Genomic DNA from Hydrodictyon reticulatum and Pediastrum duplex was subjected to Illumina paired-end sequencing and the complete plastomes were assembled for each. Plastome size and gene content were characterized and compared with other plastomes from the Sphaeropleales. Homology searches using BLASTX were used to characterize introns and open reading frames (orfs ≥ 300 bp. A phylogenetic analysis of gene order across the Sphaeropleales was performed. Results The plastome of Hydrodictyon reticulatum is 225,641 bp and Pediastrum duplex is 232,554 bp. The plastome structure and gene order of H. reticulatum and P. duplex are more similar to each other than to other members of the Sphaeropleales. Numerous unique open reading frames are found in both plastomes and the plastome of P. duplex contains putative viral protein genes, not found in other Sphaeropleales plastomes. Gene order analyses support the monophyly of the Hydrodictyaceae and their sister relationship to the Neochloridaceae. Discussion The complete plastomes of Hydrodictyon reticulatum and Pediastrum duplex, representing the largest of the Sphaeropleales sequenced thus far, once again highlight the variability in size, architecture, gene order and content across the Chlorophyceae. Novel intron insertion sites and unique

    2008-06-01

    Full Text Available Abstract Background To gain insight into the branching order of the five main lineages currently recognized in the green algal class Chlorophyceae and to expand our understanding of chloroplast genome evolution, we have undertaken the sequencing of chloroplast DNA (cpDNA from representative taxa. The complete cpDNA sequences previously reported for Chlamydomonas (Chlamydomonadales, Scenedesmus (Sphaeropleales, and Stigeoclonium (Chaetophorales revealed tremendous variability in their architecture, the retention of only few ancestral gene clusters, and derived clusters shared by Chlamydomonas and Scenedesmus. Unexpectedly, our recent phylogenies inferred from these cpDNAs and the partial sequences of three other chlorophycean cpDNAs disclosed two major clades, one uniting the Chlamydomonadales and Sphaeropleales (CS clade and the other uniting the Oedogoniales, Chaetophorales and Chaetopeltidales (OCC clade. Although molecular signatures provided strong support for this dichotomy and for the branching of the Oedogoniales as the earliest-diverging lineage of the OCC clade, more data are required to validate these phylogenies. We describe here the complete cpDNA sequence of Oedogonium cardiacum (Oedogoniales. Results Like its three chlorophycean homologues, the 196,547-bp Oedogonium chloroplast genome displays a distinctive architecture. This genome is one of the most compact among photosynthetic chlorophytes. It has an atypical quadripartite structure, is intron-rich (17 group I and 4 group II introns, and displays 99 different conserved genes and four long open reading frames (ORFs, three of which are clustered in the spacious inverted repeat of 35,493 bp. Intriguingly, two of these ORFs (int and dpoB revealed high similarities to genes not usually found in cpDNA. At the gene content and gene order levels, the Oedogonium genome most closely resembles its Stigeoclonium counterpart. Characters shared by these chlorophyceans but missing in members

    Background The phylum Chlorophyta contains the majority of the green algae and is divided into four classes. While the basal position of the Prasinophyceae is well established, the divergence order of the Ulvophyceae, Trebouxiophyceae and Chlorophyceae (UTC) remains uncertain. The five complete chloroplast DNA (cpDNA) sequences currently available for representatives of these classes display considerable variability in overall structure, gene content, gene density, intron content and gene order. Among these genomes, that of the chlorophycean green alga Chlamydomonas reinhardtii has retained the least ancestral features. The two single-copy regions, which are separated from one another by the large inverted repeat (IR), have similar sizes, rather than unequal sizes, and differ radically in both gene contents and gene organizations relative to the single-copy regions of prasinophyte and ulvophyte cpDNAs. To gain insights into the various changes that underwent the chloroplast genome during the evolution of chlorophycean green algae, we have sequenced the cpDNA of Scenedesmus obliquus, a member of a distinct chlorophycean lineage. Results The 161,452 bp IR-containing genome of Scenedesmus features single-copy regions of similar sizes, encodes 96 genes, i.e. only two additional genes (infA and rpl12) relative to its Chlamydomonas homologue and contains seven group I and two group II introns. It is clearly more compact than the four UTC algal cpDNAs that have been examined so far, displays the lowest proportion of short repeats among these algae and shows a stronger bias in clustering of genes on the same DNA strand compared to Chlamydomonas cpDNA. Like the latter genome, Scenedesmus cpDNA displays only a few ancestral gene clusters. The two chlorophycean genomes share 11 gene clusters that are not found in previously sequenced trebouxiophyte and ulvophyte cpDNAs as well as a few genes that have an unusual structure; however, their single-copy regions differ

    Several species of microalgae, closely related to mesophilic lineages, inhabit the extreme environment (pH 2.5, high levels of metals) of the Spain's Aguas Agrias Stream water (AASW). Consequently, AASW constitutes an interesting natural laboratory for analysis of adaptation by microalgae to extremely stressful conditions. To distinguish between the pre-selective or post-selective origin of adaptation processes allowing the existence of microalgae in AASW, a Luria-Delbrück fluctuation analysis was performed with the chlorophycean Dictyosphaerium chlorelloides isolated from non-acidic waters. In the analysis, AASW was used as selective factor. Preselective, resistant D. chlorelloides cells appeared with a frequency of 1.1 x 10(-6) per cell per generation. AASW-resistant mutants, with a diminished Malthusian fitness, are maintained in non-extreme waters as the result of a balance between new AASW-resistant cells arising by mutation and AASW-resistant mutants eliminated by natural selection (equilibrium at c. 12 AASW-resistants per 10(7) wild-type cells). We propose that the microalgae inhabiting this stressful environment could be the descendents of chance mutants that arrived in the past or are even arriving at the present.

  7. Proliferation of group II introns in the chloroplast genome of the green alga Oedocladium carolinianum (Chlorophyceae

    2016-10-01

    Full Text Available Background The chloroplast genome sustained extensive changes in architecture during the evolution of the Chlorophyceae, a morphologically and ecologically diverse class of green algae belonging to the Chlorophyta; however, the forces driving these changes are poorly understood. The five orders recognized in the Chlorophyceae form two major clades: the CS clade consisting of the Chlamydomonadales and Sphaeropleales, and the OCC clade consisting of the Oedogoniales, Chaetophorales, and Chaetopeltidales. In the OCC clade, considerable variations in chloroplast DNA (cpDNA structure, size, gene order, and intron content have been observed. The large inverted repeat (IR, an ancestral feature characteristic of most green plants, is present in Oedogonium cardiacum (Oedogoniales but is lacking in the examined members of the Chaetophorales and Chaetopeltidales. Remarkably, the Oedogonium 35.5-kb IR houses genes that were putatively acquired through horizontal DNA transfer. To better understand the dynamics of chloroplast genome evolution in the Oedogoniales, we analyzed the cpDNA of a second representative of this order, Oedocladium carolinianum. Methods The Oedocladium cpDNA was sequenced and annotated. The evolutionary distances separating Oedocladium and Oedogonium cpDNAs and two other pairs of chlorophycean cpDNAs were estimated using a 61-gene data set. Phylogenetic analysis of an alignment of group IIA introns from members of the OCC clade was performed. Secondary structures and insertion sites of oedogonialean group IIA introns were analyzed. Results The 204,438-bp Oedocladium genome is 7.9 kb larger than the Oedogonium genome, but its repertoire of conserved genes is remarkably similar and gene order differs by only one reversal. Although the 23.7-kb IR is missing the putative foreign genes found in Oedogonium, it contains sequences coding for a putative phage or bacterial DNA primase and a hypothetical protein. Intergenic sequences are 1.5-fold

    2007-07-01

    Full Text Available Abstract Background In the Chlorophyta – the green algal phylum comprising the classes Prasinophyceae, Ulvophyceae, Trebouxiophyceae and Chlorophyceae – the chloroplast genome displays a highly variable architecture. While chlorophycean chloroplast DNAs (cpDNAs deviate considerably from the ancestral pattern described for the prasinophyte Nephroselmis olivacea, the degree of remodelling sustained by the two ulvophyte cpDNAs completely sequenced to date is intermediate relative to those observed for chlorophycean and trebouxiophyte cpDNAs. Chlorella vulgaris (Chlorellales is currently the only photosynthetic trebouxiophyte whose complete cpDNA sequence has been reported. To gain insights into the evolutionary trends of the chloroplast genome in the Trebouxiophyceae, we sequenced cpDNA from the filamentous alga Leptosira terrestris (Ctenocladales. Results The 195,081-bp Leptosira chloroplast genome resembles the 150,613-bp Chlorella genome in lacking a large inverted repeat (IR but differs greatly in gene order. Six of the conserved genes present in Chlorella cpDNA are missing from the Leptosira gene repertoire. The 106 conserved genes, four introns and 11 free standing open reading frames (ORFs account for 48.3% of the genome sequence. This is the lowest gene density yet observed among chlorophyte cpDNAs. Contrary to the situation in Chlorella but similar to that in the chlorophycean Scenedesmus obliquus, the gene distribution is highly biased over the two DNA strands in Leptosira. Nine genes, compared to only three in Chlorella, have significantly expanded coding regions relative to their homologues in ancestral-type green algal cpDNAs. As observed in chlorophycean genomes, the rpoB gene is fragmented into two ORFs. Short repeats account for 5.1% of the Leptosira genome sequence and are present mainly in intergenic regions. Conclusion Our results highlight the great plasticity of the chloroplast genome in the Trebouxiophyceae and indicate

    Full Text Available Two U.S. studies report a differential effect of identity centrality and in-group superiority on reactions to in-group victimization and in-group harm-doing. Study 1 (N = 80 found that higher identity centrality predicted less justification for freely-recalled in-group victim events, whereas higher in-group superiority predicted more justification for freely-recalled in-group harm-doing events. Study 2 (N = 105 reexamined these findings in specific contexts of historical victimization (Pearl Harbor and harm-doing (Hiroshima and Nagasaki, finding that in-group superiority was a predictor of reactions to historical in-group harm-doing (justification, emotional reactions, importance of events, whereas centrality was a predictor of reactions to historical in-group victimization.

  14. Do group-specific equations provide the best estimates of stature?

    Albanese, John; Osley, Stephanie E; Tuck, Andrew

    2016-04-01

    An estimate of stature can be used by a forensic anthropologist with the preliminary identification of an unknown individual when human skeletal remains are recovered. Fordisc is a computer application that can be used to estimate stature; like many other methods it requires the user to assign an unknown individual to a specific group defined by sex, race/ancestry, and century of birth before an equation is applied. The assumption is that a group-specific equation controls for group differences and should provide the best results most often. In this paper we assess the utility and benefits of using group-specific equations to estimate stature using Fordisc. Using the maximum length of the humerus and the maximum length of the femur from individuals with documented stature, we address the question: Do sex-, race/ancestry- and century-specific stature equations provide the best results when estimating stature? The data for our sample of 19th Century White males (n=28) were entered into Fordisc and stature was estimated using 22 different equation options for a total of 616 trials: 19th and 20th Century Black males, 19th and 20th Century Black females, 19th and 20th Century White females, 19th and 20th Century White males, 19th and 20th Century any, and 20th Century Hispanic males. The equations were assessed for utility in any one case (how many times the estimated range bracketed the documented stature) and in aggregate using 1-way ANOVA and other approaches. This group-specific equation that should have provided the best results was outperformed by several other equations for both the femur and humerus. These results suggest that group-specific equations do not provide better results for estimating stature while at the same time are more difficult to apply because an unknown must be allocated to a given group before stature can be estimated.

    Chlorophytes comprise a substantial proportion of green plant diversity. However, sister-group relationships and circumscription of the classes Chlorophyceae, Trebouxiophyceae, and Ulvophyceae have been problematic to resolve. Some analyses support a sister relationship between the trebouxiophycean Leptosira and chlorophyceans, potentially altering the circumscription of two classes, also supported by a shared fragmentation in the chloroplast gene rpoB. We sought to determine whether the latter is a synapomorphy or whether the supporting analyses are vulnerable to systematic bias. We sequenced a portion of rpoB spanning the fragmented region in strains for which it had not previously been sampled: four Chlorophyceae, six counterclockwise (CCW) group (ulvophyceans and trebouxiophyceans) and one streptophyte. We then explored the effect of subsampling proteins and taxa on phylogenetic reconstruction from a data set of 41 chloroplast proteins. None of the CCW or streptophyte strains possessed the split in rpoB, including inferred near relatives of Leptosira, but it was found in all chlorophycean strains. We reconstructed alternative phylogenies (Leptosira + Chlorophyceae and Leptosira + Chlorellales) using two different protein groups (Rpo and Rps), both subject to coding-region expansion. A conserved region of RpoB remained suitable for analysis of more recent divergences. The Rps sequences can explain earlier findings linking Leptosira with the Chlorophyceae and should be excluded from phylogenetic analyses attempting to resolve deep nodes because their expansion violates the assumptions of substitution models. We reaffirm that Leptosira is a trebouxiophycean and that fragmentation of rpoB has occurred at least twice in chlorophyte evolution.

  16. Patients with schizophrenia do not preserve automatic grouping when mentally re-grouping figures: shedding light on an ignored difficulty

    2012-08-01

    Full Text Available Looking at a pair of objects is easy when automatic grouping mechanisms bind these objects together, but visual exploration can also be more flexible. It is possible to mentally ‘re-group’ two objects that are not only separate but belong to different pairs of objects. ‘Re-grouping’ is in conflict with automatic grouping, since it entails a separation of each item from the set it belongs to. This ability appears to be impaired in patients with schizophrenia. Here we check if this impairment is selective, which would suggest a dissociation between grouping and ‘re-grouping’, or if it impacts on usual, automatic grouping, which would call for a better understanding of the interactions between automatic grouping and ‘re-grouping’. Sixteen outpatients with schizophrenia and healthy controls had to identify two identical and contiguous target figures within a display of circles and squares alternating around a fixation point. Eye-tracking was used to check central fixation. The target pair could be located in the same or separate hemifields. Identical figures were grouped by a connector (grouped automatically or not (to be re-grouped. Attention modulation of automatic grouping was tested by manipulating the proportion of connected and unconnected targets, thus prompting subjects to focalize on either connected or unconnected pairs. Both groups were sensitive to automatic grouping in most conditions, but patients were unusually slowed down for connected targets while focalizing on unconnected pairs. In addition, this unusual effect occurred only when target were presented within the same hemifield. Patients and controls differed on this asymmetry between within- and across-hemifield presentation, suggesting that patients with schizophrenia do not re-group figures in the same way as controls do. We discuss possible implications on how ‘re-grouping’ ties in with ongoing, automatic perception in healthy volunteers.

    2014-03-01

    Full Text Available This research aims to contribute to the inter-organizational network analysis perspective discussion, subsidized by the theories of collaborative networks and social capital. Elements based on social capital notions are recognized as greatly influencing collaboration and the actors’ predisposition to collaborate. The qualitative method was adopted, using as techniques the documental research, the direct observation and interviews applied to the members of the Grupo Gestor do Turismo Rural do Rio Grande do Sul (the Rural Tourism Steering Group. The validity of these techniques application was considered to enrich the analysis and to better understand the relationship among the participant actors. Results show that in purposeful and operational terms the group can be characterized as a collaborative inter-organizational network, alternating moments of intense collaboration and independent work. Also relationships based on trust, norms of reciprocity, identification, elements related to social capital theory may be decisive for the group strengthening and continuity, as it is facing a period of transformation.

  2. Do humans and nonhuman animals share the grouping principles of the iambic-trochaic law?

    Science.gov (United States)

    de la Mora, Daniela M; Nespor, Marina; Toro, Juan M

    2013-01-01

    The iambic-trochaic law describes humans' tendency to form trochaic groups over sequences varying in pitch or intensity (i.e., the loudest or highest sounds mark group beginnings), and iambic groups over sequences varying in duration (i.e., the longest sounds mark group endings). The extent to which these perceptual biases are shared by humans and nonhuman animals is yet unclear. In Experiment 1, we trained rats to discriminate pitch-alternating sequences of tones from sequences randomly varying in pitch. In Experiment 2, rats were trained to discriminate duration-alternating sequences of tones from sequences randomly varying in duration. We found that nonhuman animals group sequences based on pitch variations as trochees, but they do not group sequences varying in duration as iambs. Importantly, humans grouped the same stimuli following the principles of the iambic-trochaic law (Exp. 3). These results suggest the early emergence of the trochaic rhythmic grouping bias based on pitch, possibly relying on perceptual abilities shared by humans and other mammals, whereas the iambic rhythmic grouping bias based on duration might depend on language experience.

  3. The Mesoproterozoic volcano-sedimentary Serra do Itaberaba Group of the Central Ribeira Belt, Sao Paulo State, Brazil: implications for the age of the overlying Sao Roque Group

    2000-01-01

    One of the fundamental problems to understanding the evolution of volcano-sedimentary sequences in southeastern Brazil is constraining their depositional ages. Brasiliano tectonic and metamorphic either obscured or destroyed primary features, such as unconformities, as well as other geologic relationships. This problem is exemplified by the Serra do Itaberaba and Sao Roque groups, where the lack of data about the timing of their deposition has prevented resolution of proposed one-and two-stage geotectonic/depositional models. Recent U-Pb zircon data obtained from metavolcanic rocks in the Sao Roque Group indicate that it was deposited between 628 and 607 Ma. New U-Pb zircon data of 1395± 10 Ma for a metandesite in the basal Morro da Pedra Preta Formation (Serra do Itaberaba Group) indicate the maximum age for the beginning of the deposition of the pelites overlying MORB-like basalt. A metarhyolite of the upper unit, the Nhangucu Formation, contains two zircon populations. One yielded an age of 619 ±3 Ma, which defines the crystallization age of the rock, and the other an age of 1449 ±3 Ma, interpreted as inherited xenocrystal grains from older units of the Serra do Itaberaba Group. The younger metarhyolite was affected only by the S 2 foliation, generated during the Brasiliano orogenesis, whereas the Middle Proterozoic metavolcano-sedimentary sequence records additional metamorphic and deformational events, confirming the presence of two different geotectonic cycles.

    Almost all parents in Sweden are invited to parental groups organized by the child health service (CHS) during their child's first year, but only 40% chose to attend. The aim of this study was to describe parents' experiences of participating in these parental groups. A total of 143 parents from 71 different parental groups at 27 child health-care (CHC) centres in one Swedish county completed an online questionnaire. A majority of the parents found the parental groups to be meaningful and more than 60% met someone in the group who they socialized with outside the meetings. Parents wanted a greater focus on child-related community information, existential questions, relationships and parenting in general. Group leadership seems to be of significance to how parents in a group connect and whether the parental role is affected. Making CHC nurses more aware of the topics parents desire could help them meet parents' needs. Education and training in group dynamics and group leadership could be of value in further improving the high-quality service CHC nurses already offer parents. More knowledge is needed about what would attract those parents who do not participate. © The Author(s) 2014.

    BACKGROUND: Support groups help their participants to cope with the emotional and practical impact of their illnesses. METHODS: The effectiveness of the Leukemia Society of America support groups in enhancing the quality of life for their participants is reviewed. The groundwork, purpose, and structure of such groups, as well as alternate sources of support, are presented. Evaluation and future directions for oncology groupwork are discussed. RESULTS: Support groups complement the therapies provided by clinical practitioners and scientists by addressing the additional needs of cancer patients over the course of illness and survival. CONCLUSIONS: New concepts and methods that address the needs of specific age-groups and incorporate the newly generated data on cancer treatments will further enhance the benefits provided by support groups.

    2016-01-01

    Group settings are epicentres of emotional activity. Yet, the role of emotions in groups is poorly understood. How do group-level phenomena shape group members' emotional experience and expression? How are emotional expressions recognised, interpreted and shared in group settings? And how do such expressions influence the emotions, cognitions and behaviours of fellow group members and outside observers? To answer these and other questions, we draw on relevant theoretical perspectives (e.g., intergroup emotions theory, social appraisal theory and emotions as social information theory) and recent empirical findings regarding the role of emotions in groups. We organise our review according to two overarching themes: how groups shape emotions and how emotions shape groups. We show how novel empirical approaches break important new ground in uncovering the role of emotions in groups. Research on emotional collectives is thriving and constitutes a key to understanding the social nature of emotions.

  13. Complex distribution of EFL and EF-1α proteins in the green algal lineage

    2007-05-01

    Full Text Available Abstract Background EFL (or elongation factor-like is a member of the translation superfamily of GTPase proteins. It is restricted to eukaryotes, where it is found in a punctate distribution that is almost mutually exclusive with elongation factor-1 alpha (EF-1α. EF-1α is a core translation factor previously thought to be essential in eukaryotes, so its relationship to EFL has prompted the suggestion that EFL has spread by horizontal or lateral gene transfer (HGT or LGT and replaced EF-1α multiple times. Among green algae, trebouxiophyceans and chlorophyceans have EFL, but the ulvophycean Acetabularia and the sister group to green algae, land plants, have EF-1α. This distribution singles out green algae as a particularly promising group to understand the origin of EFL and the effects of its presence on EF-1α. Results We have sampled all major lineages of green algae for both EFL and EF-1α. EFL is unexpectedly broad in its distribution, being found in all green algal lineages (chlorophyceans, trebouxiophyceans, ulvophyceans, prasinophyceans, and mesostigmatophyceans, except charophyceans and the genus Acetabularia. The presence of EFL in the genus Mesostigma and EF-1α in Acetabularia are of particular interest, since the opposite is true of all their closest relatives. The phylogeny of EFL is poorly resolved, but the Acetabularia EF-1α is clearly related to homologues from land plants and charophyceans, demonstrating that EF-1α was present in the common ancestor of the green lineage. Conclusion The distribution of EFL and EF-1α in the green lineage is not consistent with the phylogeny of the organisms, indicating a complex history of both genes. Overall, we suggest that after the introduction of EFL (in the ancestor of green algae or earlier, both genes co-existed in green algal genomes for some time before one or the other was lost on multiple occasions.

    2013-02-01

    This study was designed to examine the early usage patterns of multiple grammatical functions of DO in children with and without specific language impairment (SLI). Children's use of this plurifunctional form is informative for evaluation of theoretical accounts of the deficit in SLI. Spontaneous uses of multiple functions of DO were analyzed in language samples from 89 children: 37 children with SLI, ages 5;0-5;6 (years;months); 37 age-equivalent children; and 15 language-equivalent children, ages 2;8-4;10. Proportion correct and types of errors produced were analyzed for each function of DO. Children with SLI had significantly lower levels of proportion correct auxiliary DO use compared to both control groups, with omissions of the DO form as the primary error type. Children with SLI had near-ceiling performance on lexical DO and elliptical DO, similar to both control groups. Plurifunctionality is not problematic: Children acquire each function of DO separately. Grammatical properties of the function, rather than surface properties of the form, dictate whether children with SLI will have difficulty using the word. Overall, these results support the extended optional infinitive account of SLI and the use of auxiliary DO omissions as part of a clinical marker for SLI.

    Scholars of ethnomethodologically informed discourse studies are often sceptical of the use of interview data such as focus group data. Some scholars quite simply reject interview data with reference to a general preference for so-called naturally occurring data. Other scholars acknowledge...... that interview data can be of some use if the distinction between natural and contrived data is given up and replaced with a distinction between interview data as topic or as resource. In greater detail, such scholars argue that interview data are perfectly adequate if the researcher wants to study the topic...... of interview interaction, but inadequate as data for studying phenomena that go beyond the phenomenon of interview interaction.

    The present study explores the notion of an out-group fear learning bias that is characterized by facilitated fear acquisition toward harm-doing out-group members. Participants were conditioned with two in-group and two out-group faces as conditioned stimuli. During acquisition, one in-group and one out-group face was paired with an aversive shock whereas the other in-group and out-group face was presented without shock. Psychophysiological measures of fear conditioning (skin conductance and pupil size) and explicit and implicit liking exhibited increased differential responding to out-group faces compared to in-group faces. However, the results did not clearly indicate that harm-doing out-group members were more readily associated with fear than harm-doing in-group members. In contrast, the out-group face not paired with shock decreased conditioned fear and disliking at least to the same extent that the shock-associated out-group face increased these measures. Based on these results, we suggest an account of the out-group fear learning bias that relates to an attentional bias to process in-group information. Copyright © 2017 The Authors.

    Many prostate cancer support groups (PCSGs) have formed in North America during the past decade, yet their operation or factors influencing sustainability are poorly understood. This article reports micro (intragroup), meso (intergroup), and macro (group/structure) analyses drawn from the fieldwork and participant observations conducted for an ethnographic study of PCSGs based in British Columbia, Canada. The findings indicate that effective group leadership is integral to group sustainability and the recruitment and retention of attendees. At the meso level, intergroup connections and communication were often informal; however, the primary purpose of all the PCSGs was to provide information and support to men and their families. Many PCSGs were uncertain how formal associations with cancer fund-raising societies would influence group effectiveness. Macro issues such as prostate cancer activism resided with individual group "champions" through activities coordinated by provincial and national PCSG organizations. However, activism did not guarantee group sustainability. The study findings reveal why some groups flourish while others appear untenable, and form the basis for discussion about how PCSG sustainability might be best achieved.

    Investigation into predictors for treatment outcome is essential to improve the clinical efficacy of therapeutic multipotent mesenchymal stromal cells (MSCs). We therefore studied the possible harmful impact of immunogenic ABO blood groups antigens - genetically governed antigenic determinants - at all given steps of MSC-therapy, from cell isolation and preparation for clinical use, to final recipient outcome. We found that clinical MSCs do not inherently express or upregulate ABO blood group antigens after inflammatory challenge or in vitro differentiation. Although antigen adsorption from standard culture supplements was minimal, MSCs adsorbed small quantities of ABO antigen from fresh human AB plasma (ABP), dependent on antigen concentration and adsorption time. Compared to cells washed in non-immunogenic human serum albumin (HSA), MSCs washed with ABP elicited stronger blood responses after exposure to blood from healthy O donors in vitro, containing high titers of ABO antibodies. Clinical evaluation of hematopoietic stem cell transplant (HSCT) recipients found only very low titers of anti-A/B agglutination in these strongly immunocompromised patients at the time of MSC treatment. Patient analysis revealed a trend for lower clinical response in blood group O recipients treated with ABP-exposed MSC products, but not with HSA-exposed products. We conclude, that clinical grade MSCs are ABO-neutral, but the ABP used for washing and infusion of MSCs can contaminate the cells with immunogenic ABO substance and should therefore be substituted by non-immunogenic HSA, particularly when cells are given to immunocompentent individuals.

    2015-05-01

    In non-gang populations, the degree of identification with an in-group and perceptions of out-group entitativity, the perception of an out-group as bonded or unified, are important contributors to group-based aggression or vicarious retribution. The link between these factors and group-based aggression, however, has not been examined in the context of street gangs. The current study assessed the relationship among in-group identification, perceptions of out-group entitativity, and the willingness to retaliate against members of rival groups who did not themselves attack the in-group among juvenile gang and non-gang members in London. Our results showed the predicted membership (gang/non-gang) × in-group identification × entitativity interaction. Decomposition of the three-way interaction by membership revealed a significant identification × entitativity interaction for gang, but not for non-gang members. More specifically, gang members who identify more strongly with their gang and perceived a rival group as high on entitativity were more willing to retaliate against any of them. In addition, entitativity was a significant predictor of group-based aggression after controlling for gender, in-group identification, and gang membership. Our results are consistent with socio-psychological theories of group-based aggression and support the proposal that such theories are applicable for understanding gang-related violence. Aggr.

    Human blood can be divided into groups, which is a method of blood classification based on the presence or absence of inherited erythrocyte surface antigens that can elicit immune response. According to the International Society of Blood Transfusion, there are 341 blood group antigens collected in 35 blood group systems. These antigens can be proteins, glycoproteins or glycosphingolipids, and function as transmembrane transporters, ion channels, adhesion molecules or receptors for other proteins. The majority of blood group antigens is present also on another types of cells. Due to their localization on the surface of cells, blood group antigens can act as receptors for various pathogens or their toxins, such as protozoa (malaria parasites), bacteria (Helicobacter pylori, Vibrio cholerae and Shigella dysenteriae) and viruses (Noroviruses, Parvoviruses, HIV). If the presence of group antigen (or its variant which arised due to mutation) is beneficial for the host (e.g. because pathogens are not able to bind to the cells), the blood group may become a selection trait, leading to its dissemination in the population exposed to that pathogen. There are thirteen blood group systems that can be related to pathogen resistance, and it seems that the particular influence was elicit by malaria parasites. It is generally thought that the high incidence of blood groups such as O in the Amazon region, Fy(a-b-) in Africa and Ge(-) in Papua-New Guinea is the result of selective pressure from malaria parasite. This review summarizes the data about relationship between blood groups and resistance to pathogens.

    Full Text Available The year 1988 was an important landmark for afro-brazilian communities, when, for the first time, their constitutional rights were accorded to their land and exploitation of their cultural practices. Since then, several communities were internally reorganized and externally articulated in order to rescue and revitalize the celebrations, festivities and traditions inherited from their ancestors. In this context, this paper seeks to reflect about the processes of cultural (resignification and (reinvention in the maroon communities of Moça Santa, municipality of Chapada do Norte and Quilombo, municipality of Minas Novas, in Vale do Jequitinhonha/MG. The rescue and recovery of dances, songs and celebrations locally regarded as “traditional”, like the Curiango’s group in Moça Santa, and the Marujada’s group in Quilombo, gained acceptance from the recognition of these territories as Quilombo, mobilizing youth and adults to practice and dissemination their cultural expressions. Through empirical observations and reports from the field, you realize that the Curiango and Marujada groups are important symbolic and cultural references of these territories, contributing to integration and community cohesion, for affirmation of his afro-brazilian identity, and especially, for legitimation of his self - recognition as Quilombo.

    Hispanic preschoolers are less active than their non-Hispanic peers. As part of a feasibility study to assess environmental and parenting influences on preschooler physical activity (PA) (Niños Activos), the aim of this study was to identify what parents do to encourage or discourage PA among Hispanic 3-5 year old children to inform the development of a new PA parenting practice instrument and future interventions to increase PA among Hispanic youth. Nominal Group Technique (NGT), a structured multi-step group procedure, was used to elicit and prioritize responses from 10 groups of Hispanic parents regarding what parents do to encourage (5 groups) or discourage (5 groups) preschool aged children to be active. Five groups consisted of parents with low education (less than high school) and 5 with high education (high school or greater) distributed between the two NGT questions. Ten NGT groups (n = 74, range 4-11/group) generated 20-46 and 42-69 responses/group for practices that encourage or discourage PA respectively. Eight to 18 responses/group were elected as the most likely to encourage or discourage PA. Parental engagement in child activities, modeling PA, and feeding the child well were identified as parenting practices that encourage child PA. Allowing TV and videogame use, psychological control, physical or emotional abuse, and lack of parental engagement emerged as parenting practices that discourage children from being active. There were few differences in the pattern of responses by education level. Parents identified ways they encourage and discourage 3-5 year-olds from PA, suggesting both are important targets for interventions. These will inform the development of a new PA parenting practice scale to be further evaluated. Further research should explore the role parents play in discouraging child PA, especially in using psychological control or submitting children to abuse, which were new findings in this study.

    The main purpose of this paper is to better understand groups that do not have the unique product property. In particular, the goal is to better understand Promislow's example, G, of such a group. In doing so, we will develop methods for generating examples of other sets that do not have the unique product property. With these methods we can show that there exists other distinct 14 element, square, non-unique product sets in G that are not inversions or translations. Also, this paper answers ...

    This section presents the results of the questionnaires with the recommendations from the 3 discussion groups. The questions approached are as follows: 1 - Discussion Group 1, 2 and 3 - Senior Management / Organizational Issues: Do Senior Managers understand the root cause analysis (RCA) process? Who in the organization is responsible for RCA? Are there regulatory requirements / influence? Does the culture of the organization affect the RCA process? Specific Recommendations. 2 - Discussion Group 1, 2 and 3 - Systematic Methodology / Tools: What are the challenges in using available analyses tools for identification of Human and Organisational Factors (HOF) in RCA? How do you 'handle' the perceived qualitative/subjective nature of HOF? Is the vocabulary used in RCA methodologies consistent? Will organizational issues be identified in analyses less intensive than RCA? Are you able to identify organizational issues from a single event? Is it difficult to make a clear link between RCA and CAs? What do you do if your scope expands? Recommendations. 3 - Discussion Group 1, 2 and 3 - Team Composition / Attributes: What are the challenges associated in team / individual competence? Is there management / HOF representation on the team? Does the level of the management sponsor affect the willingness of the organization to accept the HOF in RCA? Are RCA results presented to management? Who presents? Recommendations. 4 - Discussion Group 1, 2 and 3 - Learning: How many RCAs are done in a year? Is this sufficient? Could you identify organizational issues using an 'Apparent Cause Analysis' method? Are events with HOF issues trended in your organization? How do you know you have a learning organization? How can you measure the effectiveness of CAs?

    Full Text Available Os grupos sociais categoriais são alvo, desde o pós-guerra, de uma intenso esforço de compreensão e demarcação conceitual, principalmente por parte dos psicólogos sociais europeus. A ampliação desta importância na pauta dos pesquisadores se deve ao aumento da presença relativa deste tipo de grupo no cenário das relações sociais e de suas conseqüências na produção das identidades sociais. Neste trabalho indicamos como o crescimento da importância dada aos grupos categoriais acompanha o esvaziamento progressivo do imaginário dos grupos, que passam a operar socialmente menos a partir das relações efetivas entre os indivíduos que os compõem e mais pela sua borda, isto é, o nome do grupo. Chamamos de grupos-nome a esses grupos virtualizados, que não têm presença material mas apenas imagética. Os grupos-nome tendem a ser mais freqüentes do que os grupos "vivos" na medida em que facilitam um relacionamento mais descompromissado entre os indivíduos e portanto mais confortável pela facilidade com a qual os indivíduos poderiam "trocar" de grupo social. Como efeitos da incidência dos grupos-nome destacam-se a transformação dos grupos face a face, a ampliação de mecanismos de controle e manipulação social e o incremento da violência.Categorial social groups have been studied with more interest by the European social psychologists after Second World War.

    The recently adopted Directive on non-financial reporting (Directive 2014/95/EU) and several CSR frameworks are based on the assumption that groups of undertakings adopt, report and implement one group policy. This is a very important but also rather unique approach to groups. This article first...... shows how the Directive as well as a few CSR frameworks intend to be implemented in groups and next it discusses potential barriers to do so. Even though company law does not always facilitate the adoption, communication and implementation of a group CSR policy, it may not in practice be a problem to do...... so. However, it is shown that doing so may have unforeseen consequences for the parent undertaking. To avoid them, it is recommended to make adjustments to the implementation of the group policy....

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

    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. © 2014 by the Society for Personality and Social Psychology, Inc.

  7. Do diagnosis-related group-based payments incentivise hospitals to adjust output mix?

    Liang, Li-Lin

    2015-04-01

    This study investigates whether the diagnosis-related group (DRG)-based payment method motivates hospitals to adjust output mix in order to maximise profits. The hypothesis is that when there is an increase in profitability of a DRG, hospitals will increase the proportion of that DRG (own-price effects) and decrease those of other DRGs (cross-price effects), except in cases where there are scope economies in producing two different DRGs. This conjecture is tested in the context of the case payment scheme (CPS) under Taiwan's National Health Insurance programme over the period of July 1999 to December 2004. To tackle endogeneity of DRG profitability and treatment policy, a fixed-effects three-stage least squares method is applied. The results support the hypothesised own-price and cross-price effects, showing that DRGs which share similar resources appear to be complements rather substitutes. For-profit hospitals do not appear to be more responsive to DRG profitability, possibly because of their institutional characteristics and bonds with local communities. The key conclusion is that DRG-based payments will encourage a type of 'product-range' specialisation, which may improve hospital efficiency in the long run. However, further research is needed on how changes in output mix impact patient access and pay-outs of health insurance. Copyright © 2014 John Wiley & Sons, Ltd.

    Humans everywhere cooperate in groups to achieve benefits not attainable by individuals. Individual effort is often not automatically tied to a proportionate share of group benefits. This decoupling allows for free-riding, a strategy that (absent countermeasures) outcompetes cooperation. Empirically and formally, punishment potentially solves the evolutionary puzzle of group cooperation. Nevertheless, standard analyses appear to show that punishment alone is insufficient, because second-order free riders (those who cooperate but do not punish) can be shown to outcompete punishers. Consequently, many have concluded that other processes, such as cultural or genetic group selection, are required. Here, we present a series of agent-based simulations that show that group cooperation sustained by punishment easily evolves by individual selection when you introduce into standard models more biologically plausible assumptions about the social ecology and psychology of ancestral humans. We relax three unrealistic assumptions of past models. First, past models assume all punishers must punish every act of free riding in their group. We instead allow punishment to be probabilistic, meaning punishers can evolve to only punish some free riders some of the time. This drastically lowers the cost of punishment as group size increases. Second, most models unrealistically do not allow punishment to recruit labor; punishment merely reduces the punished agent's fitness. We instead realistically allow punished free riders to cooperate in the future to avoid punishment. Third, past models usually restrict agents to interact in a single group their entire lives. We instead introduce realistic social ecologies in which agents participate in multiple, partially overlapping groups. Because of this, punitive tendencies are more expressed and therefore more exposed to natural selection. These three moves toward greater model realism reveal that punishment and cooperation easily evolve by

    Full Text Available Previous research has demonstrated that, when negative metastereotypes are made salient, members of low status groups help members of high status groups in order to improve the reputation of their low status group and its associated social identity. The present research investigated three potential moderators of low status groups’ outgroup helping: ingroup identification, audience group membership, and perceived reputational benefit. In Study 1 (N = 112 we found that members of a low status group (Keele University students were most likely to offer to help raise funds for a high status group (University of Birmingham students when they were high identifiers who had considered a negative metastereotype and believed that their responses would be viewed by an outgroup member. In Study 2 (N = 100 we found a similar effect in an intergroup context that referred to psychology students (low status ingroup and junior doctors (high status outgroup, showing that the effect was limited to people who perceived reputational benefit in helping the outgroup. The practical and social implications of these findings are discussed in relation to intergroup contact and international relations.

    How do children and youth come to understand what it means to be a member of a particular race, gender, and other social groups? How do they come to hold beliefs about the groups that they do and do not belong to? Both news stories and fictional narratives that we are tuned into as a culture tell stories about what it means to be a member of a particular social group. In this review article, we relate the latest scientific knowledge on news and entertainment media representations of race, gender and other social categories and what they tell us about how these messages are taken in and processed by developing minds. We include research on identity development, social learning about members of other groups, and both positive and negative behavioral outcomes to cultural messages about race, gender, and other social categories. We offer recommendations for stakeholders to understand the role of the media in educating youth about race, gender and other social categories.

    2015-01-01

    Self-help groups are beneficial for many people with addiction, predominantly through 12-step models. Yet obstacles to attendance also occur. We explored attendance patterns and attitudes toward self-help groups by 165 outpatient females with co-occurring posttraumatic stress disorder (PTSD) and substance use disorder (SUD), the first study of its kind. Cross-sectional self-report data compared adults versus adolescents, and those currently attending self-help versus not attending. We also explored attendance in relation to perceptions of the PTSD/SUD relationship and symptom severity. Adults reported higher attendance at self-help than adolescents, both lifetime and currently. Among current attendees, adults also attended more weekly groups than adolescents. Yet only a minority of both age cohorts attended any self-help in the past week. Adults perceived a stronger relationship between PTSD and SUD than adolescents, but both age groups gave low ratings to the fact that self-help groups do not address PTSD. That item also had low ratings by both those currently attending and not attending self-help. Analysis of those not currently attending identified additional negative attitudes toward self-help (spirituality, addiction as a life-long illness, sayings, and the fellowship). Symptom severity was not associated with attendance, but may reflect a floor effect. Finally, a surprising finding was that all-female groups were not preferred by any subsample. Conclusions/Importance. Creative solutions are needed to address obstacles to self-help among this population. Addressing trauma and PTSD, not just SUD, was valued by females we surveyed, and may be more helpful than all-female groups per se.

    1997-08-01

    This report describes an architecture and implementation for doing group key management over a data communications network. The architecture describes a protocol for establishing a shared encryption key among an authenticated and authorized collection of network entities. Group access requires one or more authorization certificates. The implementation includes a simple public key and certificate infrastructure. Multicast is used for some of the key management messages. An application programming interface multiplexes key management and user application messages. An implementation using the new IP security protocols is postulated. The architecture is compared with other group key management proposals, and the performance and the limitations of the implementation are described.

    2007-04-01

    Although online focus groups are emerging as a worthwhile methodological approach for qualitative researchers, reporting has been constrained in several ways. The majority of studies report asynchronous groups, whereas others employ synchronous exchanges, the efficacy of which with young people has seldom been explored. Considering the popularity of the Internet as a communication tool for young people, this missed opportunity is surprising. Based on a series of synchronous online focus groups with young people, the authors explore why this approach might be an effective way of engaging young people with appearance-related concerns in research. In this article, they discuss the process of hosting and moderating synchronous online focus groups, highlighting some of the ethical, pragmatic, and personal challenges that might face researchers using this method. Through a reflexive approach, they intend to inform and encourage qualitative researchers to consider alternative ways of engaging young people in research.

    Schneibel, Dan

    The phenomenological-existential therapy known as gestalt therapy sees awareness as its major goal. Clients are helped to become aware of what they are doing, how they are doing it, and how they can change themselves while, at the same time, learning to accept and value themselves. An important topic in the gestalt group process is the key…

  20. FAR Research Project: What do we know about group audits

    Hanes Downey, Denise; Gold, A.H.

    Despite concerns about the quality of group audits, recently raised by practice, inspectors, regulators, and standard setters, only a limited number of academic studies have specifically examined these engagements to date. This paper first describes some of the concerns about group audits to explain

  1. Effects of rooting via out-groups on in-group topology in phylogeny.

    Ackerman, Margareta; Brown, Daniel G; Loker, David

    Users of phylogenetic methods require rooted trees, because the direction of time depends on the placement of the root. While phylogenetic trees are typically rooted by using an out-group, this mechanism is inappropriate when the addition of an out-group changes the in-group topology. We perform a formal analysis of phylogenetic algorithms under the inclusion of distant out-groups. It turns out that linkage-based algorithms (including UPGMA) and a class of bisecting methods do not modify the topology of the in-group when an out-group is included. By contrast, the popular neighbour joining algorithm fails this property in a strong sense: every data set can have its structure destroyed by some arbitrarily distant outlier. Furthermore, including multiple outliers can lead to an arbitrary topology on the in-group. The standard rooting approach that uses out-groups may be fundamentally unsuited for neighbour joining.

    2014-01-01

    Geometric group theory refers to the study of discrete groups using tools from topology, geometry, dynamics and analysis. The field is evolving very rapidly and the present volume provides an introduction to and overview of various topics which have played critical roles in this evolution. The book contains lecture notes from courses given at the Park City Math Institute on Geometric Group Theory. The institute consists of a set of intensive short courses offered by leaders in the field, designed to introduce students to exciting, current research in mathematics. These lectures do not duplicate standard courses available elsewhere. The courses begin at an introductory level suitable for graduate students and lead up to currently active topics of research. The articles in this volume include introductions to CAT(0) cube complexes and groups, to modern small cancellation theory, to isometry groups of general CAT(0) spaces, and a discussion of nilpotent genus in the context of mapping class groups and CAT(0) gro...

    Social animals vary in their ability to compete with group members over shared resources and also vary in their cooperative efforts to produce these resources. Competition among groups can promote within-group cooperation, but many existing models of intergroup cooperation do not explicitly account...... of two roles, with relative competitive efficiency and the number of individuals varying between roles. Players in each role make simultaneous, coevolving decisions. The model predicts that although intergroup competition increases cooperative contributions to group resources by both roles, contributions...... are predominantly from individuals in the less competitively efficient role, whereas individuals in the more competitively efficient role generally gain the larger share of these resources.

    Full Text Available Organizations are operating in a dynamic and turbulent environment. In these conditions, they have to make decisions for new problems or situations. Most of decisions are therefore non-programmed and unstructured, accompanied by risk and uncertainty. Moreover, the problems and situations are complex. All organizations are oriented towards group decisionmaking processes, as useful tools to cope with uncertainty and complexity. Apart from the necessity, companies are turning towards participatory processes also to benefit from the important advantages that these processes offer. Organizations have realized the importance of group decision-making processes to contribute to the creation of sustainable competitive advantages. Main objective of this paper is to show that group decision-making processes do not offer guarantee for good decisions, because the effectiveness of group is affected by many factors. So, the first thing done in this paper is discussing about the benefits and limitations that accompany the use of groups with decision-making purpose. Afterwards, we stop on the different factors that influence the group’s ability to make good decisions. The aim is to emphasize that regardless of the many advantages of groups, some factors as group size, type of communication within the group, leadership style, the norms, the differentiation of roles and statuses, cohesion and compliance degree should be the main elements to keep into consideration because they affect the effectiveness of group. In this regard, is discussed how such factors influence the quality of decision and then we try to draw some conclusions that can improve and make better and easier group decision-making processes.

    Full Text Available O presente estudo tem como objetivo analisar, por meio da técnica do Grupo Focal, o entendimento de adolescentes em relação à saúde bucal. A pesquisa foi realizada em três escolas públicas da cidade de Araçatuba, Estado de São Paulo, com dez alunos em cada uma delas. Para a realização dos grupos focais foram abordadas as seguintes palavras, presentes em perguntas de questionários sobre saúde bucal, as quais apresentaram altos índices de erros: saúde bucal; placa bacteriana; dente permanente; flúor; gengiva sangra?; fio dental; transmissão da cárie. Durante as discussões dos grupos focais, observou-se que muitos adolescentes ficavam surpresos com a situação a qual foram submetidos e com o tema que estavam discutindo. A palavra ‘saúde bucal’ foi associada à condição de limpeza dacavidade bucal, não identificando a saúde bucal como parte da saúde geral. O termo ‘transmissão da cárie’ não teve um entendimento suficiente. A expressão ‘dente permanente’ foi bem compreendida, sendo associada a um tipo de dente que não seria mais substituído.A palavra ‘flúor’ teve maior associação à função de limpeza do que à proteção dos dentes. Conclui-se que a utilização da técnica do Grupo Focal é de grande importância na interpretação do conhecimento dos adolescentes sobre saúde bucal e na adequação da terminologia de questionários sobre o mesmo tema.This study aims to the understanding of adolescents regarding oral health, using the Focus Group technique.

    Full Text Available Low-income residents are among the most vulnerable groups to climate change in urban areas, particularly regarding heat stress. However, their perceptions about heat and the impacts they face go often undocumented, and are seldom considered in decision-making processes delivering adaptation. This paper presents a robust tool to allow the integration of perception, concerns and impacts of different income groups in urban adaptation planning and governance, using the City of New York as a case study. Employing online interviews—a solid method to reach poorer households—and Fuzzy Cognitive Mapping, we compare impacts and adaptation perception to heat and simulate adaptation scenarios. Results reveal that lower income groups are more concerned about impacts of heat waves than middle- and high-income populations. All income groups see citizens more in charge of adaptation, although more people from the lower income groups regard it necessary to do much more to protect themselves, proportionately more people from the higher income groups think they are doing the right amount. The scenario analysis shows that, compared to investments in the water/electricity and health system, improvements in the transit system would yield the largest decrease in negative impacts during heat, benefitting all income groups jointly.

  15. Blood group astrology - why the AB0 blood groups do not determine the human character nor the appropriate nutrition

    Directory of Open Access Journals (Sweden)

    Martina Gajšek Grbec

    2016-04-01

    Full Text Available AB0 blood groups are inherited markers on blood cells. Since their discovery, there were numerous attempts to be attributed a wide variety of biological functions they don’t possess. The purpose of this article is primarily to inform the professional, as well as lay public that the theory of healthy nutrition based on AB0 blood groups represents nothing more than a pseudoscience used for mass exploitation and commercial purposes. ABO blood groups were attributed such characteristics by naturopathic doctor Peter D'Adamo, who on the basis of false methods and erroneous assumptions wrote a bestseller "Eat Right For Your Type". It claims that the blood groupsAB0 represent a "key to the functioning of our immune system" and that the blood group based diet represents a “key to the health of every man”. As in the case of nutrition based on the ABO blood groups, the scientific knowledge in the field of immunohematology is misused to mislead the lay public, we are obliged to explain the real meaning and the role of blood groups in health and disease, the misuse of blood groups in relation to healthy nutrition.

    Though wide disparities in wealth have been documented across racial/ethnic groups, it is largely unknown whether differences in wealth are associated with health disparities within racial/ethnic groups. Data from the Survey of Consumer Finances (2004, ages 25-64) and the Health and Retirement Survey (2004, ages 50+), containing a wide range of assets and debts variables, were used to calculate net worth (a standard measure of wealth). Among non-Hispanic black, Hispanic and non-Hispanic white populations, we tested whether wealth was associated with self-reported poor/fair health status after accounting for income and education. Except among the younger Hispanic population, net worth was significantly associated with poor/fair health status within each racial/ethnic group in both data sets. Adding net worth attenuated the association between education and poor/fair health (in all racial/ethnic groups) and between income and poor/fair health (except among older Hispanics). The results add to the literature indicating the importance of including measures of wealth in health research for what they may reveal about disparities not only between but also within different racial/ethnic groups.

    2016-11-01

    Full Text Available Ageing is associated with a decline in daily functioning and mobility. A physically active life and physical exercise can minimize the decline of daily functioning and improve the physical-, psychological- and social functioning of older adults. Despite several advantages of group-based exercise programs, older adults participating in such interventions often do not meet the frequency, intensity or duration of exercises needed to gain health benefits. An exercise program that combines the advantages of group-based exercises led by an instructor with tailored home-based exercises can increase the effectiveness. Technology can assist in delivering a personalized program. The aim of the study was to determine the susceptibility of older adults currently participating in a nationwide group-based exercise program to such a blended exercise program. Eight focus-groups were held with adults of 55 years of age or older. Two researchers coded independently the remarks of the 30 participants that were included in the analysis according to the three key concepts of the Self Determination Theory: autonomy, competence and relatedness. The results show that maintaining self-reliance and keeping in touch with others were the main motives to participate in the weekly group-based exercises. Participants recognized benefits of doing additional home-based exercises, but had concerns regarding guidance, safety and motivation. Furthermore, some participants strongly rejected the idea to use technology to support them in doing exercises at home, but the majority was open to it. Insights are discussed how these findings can help design novel interventions that can increase the wellbeing of older adults and preserve an independent living.

    Existing reliable ordered group communication protocols have been developed for local-area networks and do not, in general, scale well to large numbers of nodes and wide-area networks. The InterGroup suite of protocols is a scalable group communication system that introduces a novel approach to handling group membership, and supports a receiver-oriented selection of service. The protocols are intended for a wide-area network, with a large number of nodes, that has highly variable delays and a high message loss rate, such as the Internet. The levels of the message delivery service range from unreliable unordered to reliable group timestamp ordered.

  4. How to conduct focus groups: researching group priorities through discussion.

    Science.gov (United States)

    1992-01-01

    Focus groups serve to uncover priorities and beliefs of a target group, but health project designers do not always take the time to seek this information beforehand. Focus groups also allow various local subgroups to communicate their concerns before the project starts. Focus groups can also breed ideas and dialogue that individual interviews cannot and they provide baseline information so managers can determine if attitudes or priorities have resulted from the project. Diverse people have different beliefs, e.g., women who have young children view oral rehydration therapy differently from women with no children. Project designers can use these basic differences to arrive at some conclusions about general attitudes. Focus group facilitators should have a discussion outline to help keep the group on the topic of concern. They should limit sessions to 60-90 minutes. Each focus groups should include 8-10 people. It is important to have members of various community subgroups in each group. Yet group designers should be careful not to include within the same group, those who may intimidate other people in the group, e.g., in situations where farmers depend on middlemen, farmers may not be open if middlemen are also in the focus group. Facilitators should launch each session with an attempt to encourage the members to be open and to feel comfortable. For example, in Malawi, a facilitator leads her focus group discussions with songs. Stories are another icebreaker. It is important that all focus groups centering around a certain project discuss the same topics. Facilitators need to stress to the group that all discussions are to be kept confidential. The designers should also carefully word the questions so that facilitators will not impart their bias. Facilitators should not direct the group to certain conclusions, but instead keep the discussions focused.

    2003-03-01

    Full Text Available Median nerve entrapment in the palm to wrist segment is known as carpal tunnel syndrome (CTS. Electromyography is the best evaluation test to confirm the disease, as it shows a median reduced conduction velocity and/or conduction block; however, the usual CTS electrodiagnostic tests do not separate segmental demyelination alone from segmental demyelination plus secondary axonal degeneration. We studied 100 hands from CTS patients (classified as mild, moderate, and severe, and 50 hands from normal subjects. The median palmar sensory nerve action potential (SNAP amplitude was measured and compared between the two groups. It would be expected that SNAP was normal if no axonal degeneration had occurred. The results showed that in mild CTS group and part of moderate CTS group SNAP amplitude was normal, whereas in severe CTS group, and part of moderate group SNAP amplitude was reduced, proving that axonal degeneration was involved. As it is well stated that axonal lesions have worse prognosis than segmental demyelinating ones, this simple test may help to preditic the CTS outcome and treatment.A compressão do nervo mediano no segmento punho-palma produz uma entidade clínica conhecida como síndrome do túnel do carpo (STC.

    Concern has been expressed at the poor uptake of evidence into clinical practice. This is despite the fact that continuing education is an embedded feature of quality assurance in general practice. There are a variety of clinical practice education methods available for dissemination of new evidence. Recent systematic reviews indicate that the effectiveness of these different strategies is extremely variable. Our aim was to determine whether a peer-led small group education pilot programme used to promote rational GP prescribing is an effective tool in changing practice when added to prescribing audit and feedback, academic detailing and educational bulletins, and to determine whether any effect seen decays over time. A retrospective analysis of a controlled trial of a small group education strategy with 24 month follow-up was carried out. The setting was an independent GPs association (IPA) of 230 GPs in the Christchurch New Zealand urban area. All intervention and control group GPs were already receiving prescribing audit and feedback, academic detailing and educational bulletins. The intervention group were the first 52 GPs to respond to an invitation to pilot the project. Two control groups were used, one group who joined the pilot later and a second group which included all other GPs in the IPA. The main outcome measures were targeted prescribing data for 12 months before and 24 months after each of four education sessions. An effect in the expected direction was seen in six of the eight key messages studied. This effect was statistically significant for five of the eight messages studied. The effect size varied between 7 and 40%. Where a positive effect was seen, the effect decayed with time but persisted to a significant level for 6-24 months of observation. The results support a positive effect of the education strategy on prescribing behaviour in the intervention group for most outcomes measured. The effect seen is statistically significant, sustained and

  9. Do business groups affect corporate cash holdings? Evidence from a transition economy

    Full Text Available We examine whether business groups’ influence on cash holdings depends on ownership. Group affiliation can increase firms’ agency costs or benefit firms by providing an internal capital market, especially in transition economies characterized by weak investor protection and difficult external capital acquisition. A hand-collected dataset of Chinese firms reveals that group affiliation decreases cash holdings, alleviating the free-cash-flow problem of agency costs. State ownership and control of listed firms moderate this benefit, which is more pronounced when the financial market is less liquid. Group affiliation facilitates related-party transactions, increases debt capacity and decreases investment-cash-flow sensitivity and overinvestment. In transitional economies, privately controlled firms are more likely to benefit from group affiliation than state-controlled firms propped up by the government.

  10. Identifying Differences in Cultural Behavior in Online Groups

    Energy Technology Data Exchange (ETDEWEB)

    Gregory, Michelle L.; Engel, David W.; Bell, Eric B.; Mcgrath, Liam R.

    2012-07-23

    We have developed methods to identify online communities, or groups, using a combination of structural information variables and content information variables from weblog posts and their comments to build a characteristic footprint for groups. We have worked with both explicitly connected groups and 'abstract' groups, in which the connection between individuals is in interest (as determined by content based features) and behavior (metadata based features) as opposed to explicit links. We find that these variables do a good job at identifying groups, placing members within a group, and helping determine the appropriate granularity for group boundaries. The group footprint can then be used to identify differences between the online groups. In the work described here we are interested in determining how an individual's online behavior is influenced by their membership in more than one group. For example, individuals belong to a certain culture; they may belong as well to a demographic group, and other 'chosen' groups such as churches or clubs. There is a plethora of evidence surrounding the culturally sensitive adoption, use, and behavior on the Internet. In this work we begin to investigate how culturally defined internet behaviors may influence behaviors of subgroups. We do this through a series of experiments in which we analyze the interaction between culturally defined behaviors and the behaviors of the subgroups. Our goal is to (a) identify if our features can capture cultural distinctions in internet use, and (b) determine what kinds of interaction there are between levels and types of groups.

  12. ALIGNMENTS OF GROUP GALAXIES WITH NEIGHBORING GROUPS

    2009-01-01

    Using a sample of galaxy groups found in the Sloan Digital Sky Survey Data Release 4, we measure the following four types of alignment signals: (1) the alignment between the distributions of the satellites of each group relative to the direction of the nearest neighbor group (NNG); (2) the alignment between the major axis direction of the central galaxy of the host group (HG) and the direction of the NNG; (3) the alignment between the major axes of the central galaxies of the HG and the NNG; and (4) the alignment between the major axes of the satellites of the HG and the direction of the NNG. We find strong signal of alignment between the satellite distribution and the orientation of central galaxy relative to the direction of the NNG, even when the NNG is located beyond 3r vir of the host group. The major axis of the central galaxy of the HG is aligned with the direction of the NNG. The alignment signals are more prominent for groups that are more massive and with early-type central galaxies. We also find that there is a preference for the two major axes of the central galaxies of the HG and NNG to be parallel for the system with both early central galaxies, however, not for the systems with both late-type central galaxies. For the orientation of satellite galaxies, we do not find any significant alignment signals relative to the direction of the NNG. From these four types of alignment measurements, we conclude that the large-scale environment traced by the nearby group affects primarily the shape of the host dark matter halo, and hence also affects the distribution of satellite galaxies and the orientation of central galaxies. In addition, the NNG directly affects the distribution of the satellite galaxies by inducing asymmetric alignment signals, and the NNG at very small separation may also contribute a second-order impact on the orientation of the central galaxy in the HG.

  13. Help for breastfeeding mothers. Support groups.

    Science.gov (United States)

    1991-09-01

    Many people including some health workers and physicians believe bottle feeding is just as good as breast feeding, even though bottle feeding poses some dangers to infants. Further, health workers in hospital often are too busy to counsel new mothers in breast feeding or are simply not trained to do so. Moreover, young women often live in areas away from their family and friends thus not living close to women with whom they are familiar and who could guide them in mastering breast feeding skills. So new mothers who want to breast feed have no support, lack confidence, and/or feel they cannot do so because they work or have other responsibilities. Support groups for new breast feeding mothers can provide them with the needed confidence to breast feed by allowing them to discuss concerns with other new mothers and an experienced leader and to learn the advantages of breast feeding, e.g., a breast fed infant is never constipated. A confident experienced woman in breast feeding is best suited to start a support group in a community. She needs to promote the group by talking to health workers and physicians and advertising at maternity hospitals, women's organizations, and health centers. Once the support group has become successful, several mothers can undergo training to start and lead new support groups. If no national breast feeding promotion organization exists to offer advice on starting a support group, the article provides addresses of international organizations. At support group meetings, mothers learn how to breast feed, how to express and store breast milk, breast feed inconspicuously in public, how their bodies work, and about child growth and development. Support group members from the Philippines, Belize, Trinidad and Tobago, Australia, and singapore share their experiences.

    Jetten, Jolanda; Hornsey, Matthew J

    2014-01-01

    Traditionally, group research has focused more on the motivations that make people conform than on the motivations and conditions underpinning deviance and dissent. This has led to a literature that focuses on the value that groups place on uniformity and paints a relatively dark picture of dissent and deviance: as reflections of a lack of group loyalty, as signs of disengagement, or as delinquent behavior. An alternative point of view, which has gained momentum in recent years, focuses on deviance and dissent as normal and healthy aspects of group life. In this review, we focus on the motivations that group members have to deviate and dissent, and the functional as well as the dysfunctional effects of deviance and dissent. In doing so we aim for a balanced and complete account of deviance and dissent, highlighting when such behaviors will be encouraged as well as when they will be punished.

  17. Yang-Mills theory for non-semisimple groups

    Nuyts, J; Nuyts, Jean; Wu, Tai Tsun

    2003-01-01

    For semisimple groups, possibly multiplied by U(1)'s, the number of Yang-Mills gauge fields is equal to the number of generators of the group. In this paper, it is shown that, for non-semisimple groups, the number of Yang-Mills fields can be larger. These additional Yang-Mills fields are not irrelevant because they appear in the gauge transformations of the original Yang-Mills fields. Such non-semisimple Yang-Mills theories may lead to physical consequences worth studying. The non-semisimple group with only two generators that do not commute is studied in detail.

  18. PERSPECTIVES ON GROUP WORK IN DISTANCE LEARNING

    Directory of Open Access Journals (Sweden)

    Rune Sarromaa HAUSSTÄTTER

    2007-01-01

    Full Text Available Current distance education benefits greatly from educational software that makes group work possible for students who are separated in time and space. However, some students prefer distance education because they can work on their own. This paper explores how students react to expectations on behalf of the course provider to do their assignments in collaborative groups. They are seemingly both positively surprised by the challenges that group work offer, and they are less positive to the downsides of group work. The paper discusses both sides of the experiences and suggests why this might be a paradox to live with.

    1978-01-01

    Implantation of group-III and group-V ions along [111] and [110] axes of silicon have been performed using a backscattering technique, and the depth profiles of implanted ions have been measured by the C-V method. The range of channeled Ga ions is the largest among the present data, and a p-type layer of about 6 μm is obtained by implantation at only 150 keV. The carrier profiles of channeled Al and Ga ions with deep ranges do not show any distinguishable channeled peak contrasting with the B, P, and As channeling which gives a well-defined peak. The electronic stopping cross section (S/sub e/) of channeled P ions agree well with the results of Eisen and Reddi, but in B channeling, the discrepancies of 10--20% are observed among S/sub e/ values obtained experimentally by three different groups

  1. How Do Internal and External CSR Affect Employees' Organizational Identification? A Perspective from the Group Engagement Model.

    2016-01-01

    The literature examines the impact of firms' corporate social responsibility (CSR) activities on employees' organizational identification without considering that such activities tend to have different targets. This study explores how perceived external CSR (efforts directed toward external stakeholders) and perceived internal CSR (efforts directed toward employees) activities influence employees' organizational identification. In so doing, it examines the alternative underlying mechanisms through which perceived external and internal CSR activities build employees' identification. Applying the taxonomy prescribed by the group engagement model, the study argues that the effects of perceived external and internal CSR flow through two competing mechanisms: perceived external prestige and perceived internal respect, respectively. Further, it is suggested that calling orientation (how employees see their work contributions) moderates the effects induced by these alternative forms of CSR. The model draws on survey data collected from a sample of 414 employees across five large multinationals in Pakistan. The results obtained using structural equation modeling support these hypotheses, reinforcing the notion that internal and external CSR operate through different mediating mechanisms and more interestingly employees' calling orientation moderates these relationships to a significant degree. Theoretical contributions and practical implications of results are discussed in detail.

    The extant literature suggests that poorly defined job roles make it difficult for peer support workers to be successful, and hinder their integration into multi-disciplinary workplace teams. This article uses data gathered as part of a participatory evaluation of a peer support program at a psychiatric tertiary care facility to specify the work that peers do. Data were gathered through interviews, focus groups, and activity logs and were analyzed using a modified grounded theory approach. Peers engage in direct work with clients and in indirect work that supports their work with clients. The main types of direct work are advocacy, connecting to resources, experiential sharing, building community, relationship building, group facilitation, skill building/mentoring/goal setting, and socialization/self-esteem building. The main types of indirect work are group planning and development, administration, team communication, supervision/training, receiving support, education/awareness building, and information gathering and verification. In addition, peers also do work aimed at building relationships with staff and work aimed at legitimizing the peer role. Experience, approach, presence, role modeling, collaboration, challenge, and compromise can be seen as the tangible enactments of peers' philosophy of work. Candidates for positions as peer support workers require more than experience with mental health and/or addiction problems. The job description provided in this article may not be appropriate for all settings, but it will contribute to a better understanding of the peer support worker position, the skills required, and the types of expectations that could define successful fulfillment of the role.

    The aim of this study was to investigate if by participating in action learning sets, Graduate Entry Pre-registration Nursing (GEN) students were able to engage in collaborative and deliberative learning. A single focus group interview involving eleven participants was used to collect data. Data analysis identified five themes; collaborative learning; reflection; learning through case study and problem-solving; communication, and rejection of codified learning. The themes are discussed and further analysed in the context of collaborative and deliberative learning. The evidence from this small scale study suggests that action learning sets do provide an environment where collaborative and deliberative learning can occur. However, students perceived some of them, particularly during year one, to be too 'teacher lead', which stifled learning. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Very little UK-based research has examined breast cancer-related experiences of Black and Minority Ethnic populations, and we do not know whether the psychosocial impact of diagnosis and treatment in this group is any different to that of White women. Therefore, this study examined similarities and differences amongst Black, South Asian and White breast cancer survivors. A quantitative, cross-sectional survey was conducted; 173 breast cancer survivors (80 White, 53 South Asian and 40 Black) completed a questionnaire, which assessed psychological functioning, social support, body image and beliefs about cancer. Significant differences (p Asian participants: compared with White women, South Asian participants reported higher levels of anxiety and depression, poorer quality of life and held higher levels of internal and fatalistic beliefs pertaining to cancer. Black and South Asian women reported higher levels of body image concerns than White women, and held stronger beliefs that God was in control of their cancer. South Asian women turned to religion as a source of support more than Black and White women. This study enhances current understanding of the experience and impact of breast cancer amongst Black and South Asian women, and demonstrates similarities and differences between the ethnic groups. The findings highlight implications for healthcare professionals, particularly in relation to providing culturally sensitive care and support to their patients.

    Full Text Available O ano de 1988 representou um importante marco histórico para as comunidades afro-brasileiras, quando, pela primeira vez, lhes foram reconhecidos os direitos constitucionais às suas terras e à valorização de suas práticas culturais. Desde então, diversas comunidades se reorganizaram internamente e se articularam externamente a fim de resgatar e revitalizar as celebrações, festividades e tradições herdadas de seus antepassados. Neste contexto, o presente trabalho busca refletir sobre os processos de (resignificação e (reinvenção cultural nas comunidades quilombolas de Moça Santa, município de Chapada do Norte, e Quilombo, município de Minas Novas, Vale do Jequitinhonha/MG. O resgate e a valorização de danças, cantos e celebrações consideradas localmente como “tradicionais”, a exemplo do Grupo Curiango em Moça Santa, e do Conjunto da Marujada, em Quilombo, ganharam maior ímpeto a partir do reconhecimento destes territórios como remanescentes de quilombos, mobilizando jovens e adultos para a prática e divulgação de suas expressões culturais. Por meio de observações empíricas e de relatos obtidos em campo, percebe-se que os grupos Curiango e Marujada são importantes referências simbólico-culturais destes territórios, contribuindo para integração e coesão comunitária, para a afirmação de sua identidade afro-brasileira, e, em especial, para a legitimação de seu auto-reconhecimento como remanescentes de quilombos.

Para o presente estudo, foram definidos em processo de amostragem aleatória simples quarenta indivíduos com critérios de inclusão a partir da geração (Issei e Nisei e condição bucal (edêntulos e dentados, formando quatro grupos com dez indivíduos cada. Foram realizadas entrevistas domiciliares, com os indivíduos que preencheram os critérios de inclusão-exclusão para cada grupo. Utilizando como estratégia metodológica a construção do Discurso do Sujeito Coletivo, foram definidas as categorias de análise: motivo das perdas dentárias, momento das perdas e o papel do cirurgião-dentista. Dificuldades de acesso à assistência odontológica e a naturalização da perda dentária constituem fatores sociais e culturais fortemente imbricados que resultam em edentulismo precoce. Dor e medo são sentimentos estritamente ligados à imagem do cirurgião-dentista, ainda que se reconheça uma evolução na odontologia, tanto com relação aos equipamentos, materiais e técnicas utilizadas quanto à formação e conduta do profissional.This study assesses perceptions, memories and beliefs about tooth loss in a group of Japanese-Brazilian senior citizens, selecting forty individuals through a random sampling process, with inclusion criteria related to their background (Issei/Nissei and oral status (edentulous/non-edentulous, divided into four groups, each with ten subjects. Home interviews were conducted with individuals complying with the inclusion/exclusion criteria established for each group. Using the construction of the Collective Subject Discourse as a methodological strategy, the analysis categories were defined: cause of tooth loss, time of tooth loss and the role of the dentist. Difficulties in accessing dental care and natural acceptance of tooth loss are social and cultural factors that are

  18. How do Small Groups Promote Behaviour Change? An Integrative Conceptual Review of Explanatory Mechanisms.

    Borek, Aleksandra J; Abraham, Charles

    2018-03-01

    Small groups are used to promote health, well-being, and personal change by altering members' perceptions, beliefs, expectations, and behaviour patterns. An extensive cross-disciplinary literature has articulated and tested theories explaining how such groups develop, function, and facilitate change. Yet these theoretical understandings are rarely applied in the development, description, and evaluation of health-promotion, group-based, behaviour-change interventions. Medline database, library catalogues, search engines, specific journals and reference lists were searched for relevant texts. Texts were reviewed for explanatory concepts or theories describing change processes in groups, which were integrated into the developing conceptual structure. This was designed to be a parsimonious conceptual framework that could be applied to design and delivery. Five categories of interacting processes and concepts were identified and defined: (1) group development processes, (2) dynamic group processes, (3) social change processes, (4) personal change processes, and (5) group design and operating parameters. Each of these categories encompasses a variety of theorised mechanisms explaining individual change in small groups. The final conceptual model, together with the design issues and practical recommendations derived from it, provides a practical basis for linking research and theory explaining group functioning to optimal design of group-based, behaviour-change interventions. © 2018 The Authors.

O objetivo era distinguir o engajamento colaborativo de outras formas de participação em grupo. Apresentamos um estudo pormenorizado de aulas que ocorreram no início do ano letivo em turmas do primeiro ano. Recorremos a gravações em áudio e vídeo para categorizar a participação dos alunos durante a atividade. As categorias são inspiradas no referencial psicanalítico de Grupos de Trabalho e Suposições Básicas. Com a ajuda desses conceitos foi possível caracterizar a participação individual no grupo, atentando para os impulsos emocionais que desviaram os indivíduos da tarefa. Baseados nos dados obtidos e em outros trabalhos nos quais analisamos esses grupos isoladamente, concluímos que a participação dos alunos depende de aspectos intrínsecos da dinâmica dos grupos de aprendizagem. A colaboração e objetividade, necessárias para que o grupo funcione bem, dependem de uma interferência externa ao grupo.We observed groups of secondary school students who were challenged to conduct a research activity in physics. The objective was to distinguish collaborative engagement from other forms of group participation. We present a detailed study of lessons that occurred at the beginning of the school year in first year student classes. We used audio and video recordings to categorize the students' participation during the activity. The categories draw their inspiration from the psychoanalytical approach of Working Groups and Basic Assumptions. With the help of these concepts, it was possible to characterize individual participation in the group, paying attention to the emotional impulses that diverted individuals from the task in hand. Based on the data obtained and on other works in which we analyzed these groups in isolation, we conclude that student participation depends on intrinsic aspects of the dynamics of the

    Full Text Available Why do terrorist groups endure? This question is relevant to scholars and policy makers alike. In the past, this issue was not been addressed in a systematic fashion. Recent work investigates this question using data on transnational groups and finds that factors associated with the home country can influence the duration the group endures. Applying the theory of outbidding to terrorist group survival, we argue that strategic competition among groups predicts group duration. Using the Global Terrorism Database, we develop a dataset using the terrorist group as the unit of analysis to model the duration of group activity and thus include the largest sample of groups yet. Controlling for previous explanations of both group duration and terrorism, we find a robust effect for the impact that group competition has on terrorist group survival.

    Many survey studies in health care adjust for demographic characteristics such as age, gender, educational attainment and general health when performing statistical analyses. Whether the effects of these demographic characteristics are consistent between patient groups remains to be determined. This is important as the rationale for adjustment is often that demographic sub-groups differ in their so-called 'response tendency'. This rationale may be less convincing if the effects of response tendencies vary across patient groups. The present paper examines whether the impact of these characteristics on patients' global rating of care varies across patient groups. Secondary analyses using multi-level regression models were performed on a dataset including 32 different patient groups and 145,578 observations. For each demographic variable, the 95% expected range of case-mix coefficients across patient groups is presented. In addition, we report whether the variance of coefficients for demographic variables across patient groups is significant. Overall, men, elderly, lower educated people and people in good health tend to give higher global ratings. However, these effects varied significantly across patient groups and included the possibility of no effect or an opposite effect in some patient groups. The response tendency attributed to demographic characteristics - such as older respondents being milder, or higher educated respondents being more critical - is not general or universal. As such, the mechanism linking demographic characteristics to survey results on patient experiences with quality of care is more complicated than a general response tendency. It is possible that the response tendency interacts with patient group, but it is also possible that other mechanisms are at play.

    2018-01-01

    This study uses a quasi-experimental design to investigate what happens to individual socially responsible attitudes when they are exposed to group dynamics. Findings show that group engagement increases individual attitudes toward social responsibility. We also found that individuals with low attitudes toward social responsibility are more likely to change their opinions when group members show more positive attitudes toward social responsibility. Conversely, individuals with high attitudes do not change much, independent of group characteristics. To better analyze the effect of group dynamics, the study proposes to split social responsibility into relative and absolute components. Findings show that relative social responsibility is correlated with but different from absolute social responsibility although the latter is more susceptible than the former to group dynamics.

    How do humans and animals travel between multiple destinations on a given foraging trip? This question is of theoretical and practical interest, yet few empirical data exist to date. We examined how a group of wild chacma baboons travelled among multiple, simultaneously fruiting mountain fig trees (Ficus glumosa). In the course of a 16-month study, this highly preferred fruit was available during a 3-week period, from relatively few sites, which were also utilized by four larger baboon groups. We used directness of route and travel speed of 13 days of observation, and approach rates of 31 days of observation to differentiate between purposeful and opportunistic encounters with 50 fig trees. The study group visited a total of 30 fig trees overall, but only 8 trees per day on average. Each morning, they travelled along a highly repetitive route on all days of observation, thereby visiting 2-4 fig trees. They approached these trees rapidly along highly directed paths without intermittently exploiting other food sources that were available in large quantities. Then, they abruptly changed behaviour, switching to lower travel speed and less directed routes as they foraged on a variety of foods. They approached additional fig trees later in the day, but approach rates were similar to those at times of year when fruit of this fig species was unavailable; this suggested that encounters with trees after the behavioural switch were not planned. Comparing visits to purposefully and opportunistically encountered trees, we found no difference in the average time spent feeding or frequency of feeding supplants, suggesting that purposefully and opportunistically visited trees had similar values. We conclude that when foraging for mountain fig fruit the baboons' cognitive maps either contain information on relatively few trees or of only a single route along which several trees are situated, leading to very limited planning abilities.

    Full Text Available Variations in vegetation based on topographic location have become an interest of researchers. However, few studies have verified floristic associations related to the topographic position of a slope. In this work, we analyzed if variations in vegetation allow floristic groups to be detected in a subtropical moist forest. The vegetation was sampled in 25 plots of 400 m² distributed systematically, where individuals with a DBH ≥ 5.0 cm were measured. We sampled 1,727 individuals and 144 species. The NMDS ordination segregated three groups based on the topographic position of the slope (Monte Carlo, P ≥ 0.05; ANOSIM, P < 0.001. Euterpe edulis and Sloanea guianensis were notable in the lower and middle sections of the slope, whereas Ocotea aciphylla and Alchornea triplinervia were notable in the upper section. Some species were indicators of the analyzed sectors, such as Actinostemon concolor and Alsophila setosa in the lower section, Cyathea corcovadensis and Rudgea recurva in the middle section, and Myrcia pulchra and Podocarpus sellowii in the upper section. Our results indicate that the floristic and structural variations observed by Veloso and Klein (1959 and Klein (1980; 1984 for Vale do Itajaí in Santa Catarina are statistically valid today, because we verified the formation of different groups according to the topographic position of the slope.

    Noncommutative phase spaces are generated and classified in the framework of centrally extended anisotropic planar kinematical Lie groups as well as in the framework of noncentrally abelian extended planar absolute time Lie groups. Through these constructions the coordinates of the phase spaces do not commute due to the presence of naturally introduced fields giving rise to minimal couplings. By symplectic realizations methods, physical interpretations of generators coming from the obtained structures are given.

  6. Tax Loss Utilization and Corporate Groups: A Policy Conundrum

    Directory of Open Access Journals (Sweden)

    Stephen R. Richardson

    2013-01-01

    Full Text Available There are both theoretical and practical tax policy considerations that favour a broad recognition for the value of corporate income tax losses-- including for businesses operated within corporate groups. Ideally, an equitable and economically efficient tax system could obviate the need for loss netting against income by providing for the tax value of losses from business to be refundable by tax authorities in cash to owners. This approach, however, involves many serious difficulties, including revenue cost to governments and potential for abuse by both domestic and foreign businesses. Accordingly, loss refundability tends to be provided for only sparingly, if at all; while many corporate income tax systems—such as in the U.S. the U.K., Japan and many other OECD countries--deal with loss netting within corporate groups through a formal system of tax loss transfer or tax consolidation. While Canadian policymakers have considered introduction of such a system over a long period of time, they have yet to come up with a satisfactory formal system for Canada. So, corporate groups in Canada have been left to make do with an informal self-help loss trading system that presents a number of problems compared to formal systems. As a federal country with substantial corporate taxation levied at the provincial level, Canada appears unusually constrained in what it can do to bring greater equity and efficiency to corporate group tax loss utilization. Moreover, the inefficiencies in the current system are small in aggregate terms, and the informal self-help system has a relatively generous threshold for access. Accordingly, while Canada’s current informal self-help corporate group loss system is far from ideal, it appears to remain as a workable approach. Alternatives to the status quo should be considered cautiously, as they have the potential to do more harm than good.

    2014-06-01

    The encounter of amateur science with synthetic biology has led to the formation of several amateur/do-it-yourself biology (DIYBio) groups worldwide. Although media outlets covered DIYBio events, most seemed only to highlight the hope, hype, and horror of what DIYBio would do in the future. Here, we analyze the European amateur biology movement to find out who they are, what they aim for and how they differ from US groups. We found that all groups are driven by a core leadership of (semi-)professional people who struggle with finding lab space and equipment. Regulations on genetic modification limit what groups can do. Differences between Europe and the US are found in the distinct regulatory environments and the European emphasis on bio-art. We conclude that DIYBio Europe has so far been a responsible and transparent citizen science movement with a solid user base that will continue to grow irrespective of media attention. © 2014 The Authors.

    Full Text Available An account is given of the occurrence of Pediastrum (Chlorophyceae, Sphaeropleales in five eutrophic coastal lakes (Jamno, Bukowo, Gardno, Łebsko and Sarbsko in northern Poland, together with morphological data of the species and more detailed taxonomic and ecological information for three taxa which appear to be rare world wide. These are P. musterii, P. orientale and P. alternans; the first is recorded for the first time from central Europe. P. orientale and P. alternans show considerable morphological variability under different environmental conditions, indicating the need for further studies. The studied lakes seem to be especially favourable for Pediastrum, with a total of eight species (15 taxa in the phytoplankton noted during the summer. However, the relative frequency of the genus in the overall algal communities was low. The most frequent species were P. boryanum, P. kawraiskyi and P. duplex and these were accompanied by cyanobacteria, coccal green algae (Chlorophyceae, Chlorococcales and diatoms (Bacillariophyceae. All the Pediastrum taxa were documented using LM and SEM.

  13. Statistics on Lie groups: A need to go beyond the pseudo-Riemannian framework

    Lie groups appear in many fields from Medical Imaging to Robotics. In Medical Imaging and particularly in Computational Anatomy, an organ's shape is often modeled as the deformation of a reference shape, in other words: as an element of a Lie group. In this framework, if one wants to model the variability of the human anatomy, e.g. in order to help diagnosis of diseases, one needs to perform statistics on Lie groups. A Lie group G is a manifold that carries an additional group structure. Statistics on Riemannian manifolds have been well studied with the pioneer work of Fréchet, Karcher and Kendall [1, 2, 3, 4] followed by others [5, 6, 7, 8, 9]. In order to use such a Riemannian structure for statistics on Lie groups, one needs to define a Riemannian metric that is compatible with the group structure, i.e a bi-invariant metric. However, it is well known that general Lie groups which cannot be decomposed into the direct product of compact and abelian groups do not admit a bi-invariant metric. One may wonder if removing the positivity of the metric, thus asking only for a bi-invariant pseudo-Riemannian metric, would be sufficient for most of the groups used in Computational Anatomy. In this paper, we provide an algorithmic procedure that constructs bi-invariant pseudo-metrics on a given Lie group G. The procedure relies on a classification theorem of Medina and Revoy. However in doing so, we prove that most Lie groups do not admit any bi-invariant (pseudo-) metric. We conclude that the (pseudo-) Riemannian setting is not the richest setting if one wants to perform statistics on Lie groups. One may have to rely on another framework, such as affine connection space.

    1985-01-01

    This paper discusses the two components of the facilitative setting that are important for group formation. The first component, the ideological component, provides the basic ideas that are adopted by the emerging group. The ideological setting for group formation is produced by such things as antinuclear news coverage and concentration of news stories on hazardous waste problems, on ideas concerning the credibility of the federal government, and on the pervasivensee of ideas about general environmental problems. The organizational component of the facilitative setting provides such things as leadership ability, flexible time, resources, and experience. These are important for providing people, organization, and money to achieve group goals. By and large, the conditions conducive to group formation, growth, and survival are outside the control of decision-makers. Agencies and project sponsors are currently caught in a paradox. Actively involving the public in the decision-making process tends to contribute to the growth and survival of various interest groups. Not involving the public means damage to credibility and conflict with values concerning participatory democracy. Resolution in this area can only be achieved when a comprehensive, coordinated national approach to hazardous waste management emerges. 26 refs

    Curtright, Thomas L

    2011-01-01

    Functional conjugation methods are used to analyze the global structure of various renormalization group trajectories. With minimal assumptions, the methods produce continuous flows from step-scaling {\\sigma} functions, and lead to exact functional relations for the local flow {\\beta} functions, whose solutions may have novel, exotic features, including multiple branches. As a result, fixed points of {\\sigma} are sometimes not true fixed points under continuous changes in scale, and zeroes of {\\beta} do not necessarily signal fixed points of the flow, but instead may only indicate turning points of the trajectories.

The formation of research groups is a "new" form of organization of academic and scientific work that has recently been institutionalized by the major institutions of higher education, research and development agencies in Brazil. The research groups in Geography were treated mainly on two aspects: as important spaces for socialization of knowledge that has been growing steadily and that subsidize the training of future teachers, foster critical and reflective stance, highlighting the collective work in the study of common themes; and as important socialization spaces of knowledge that has been growing steadily, and as part of the restructuring process initiated in the 1990s, a period that the Groups Directory Research of Brazil (DGPB formalizes the groups with CNPq. By analyzing the role of postgraduate research and its relation to the formation of research groups have demonstrated that besides the expressiveness achieved with the increase of the groups in all regions of the country, this form of organization also brought repercussions to the fields of education and research segments that incorporated resets the world of work and readjusted neoliberal policies.

    Full Text Available ABSTRACT It is assumed that morphological traits of seedlings reflect different strategies in response to environmental conditions. The ecological significance of this has been widely documented in rainforests, where habitat structure and species interactions play an important role in community assembly. However, in seasonally dry ecosystems, where environmental filtering is expected to strongly influence community structure, this relationship is poorly understood. We investigated this relationship between functional groups of seedlings and life history traits and tested whether functional group predicts the ecological strategies employed by woody species to deal with the stressful conditions in seasonally dry ecosystems. Seedling functional groups, life history traits and traits that reflect ecological strategies for occupying seasonally dry environments were described for twenty-six plant species. Seedlings of species from the Caatinga vegetation exhibited a functional profile different from that observed in rainforests ecosystems. Phanerocotylar-epigeal seedlings were the most frequently observed groups, and had the largest range of ecological strategies related to dealing with seasonally dry environments, while phanerocotylar-hypogeal-reserve seedlings exhibited an increase in frequency with seasonality. We discuss these results in relation to those observed in other tropical forests and their ecological significance in seasonally dry environments.

Discussões acerca dos direitos de minorias étnicas, sejam elas feitas no âmbito de uma nação ou numa assembléia das Nações Unidas, fundamentam algumas políticas nacionais e internacionais. O autor salienta a importância de se ter clareza acerca de quais conceitos e teorias estão sendo empregados nestas discussões - conceitos como nativo ou indígena, hoje eufemismos para o primitivo, civilização ou cultura, às vezes empregados em outros tempos no lugar de raça, e teorias como a do evolucionismo. Para exemplificar as apropriações conceituais empregadas por movimentos sociais, o autor analisa os movimentos de povos ditos caçadores-coletores, como os Inuit no norte do Canadá e os Bushmen no sul do continente africano.The author analyzes the uses that certain social and political organizations make of old anthropological concepts, demonstrating how these groups interpret certain anthropological theories, taking them for themselves. Debates on the rights of ethnic groups and other minorities, at a national level or in the United Nations, are at the base of certain national and international politics. Therefore, the author points out, it is important to clarify which concepts and which theories are being used in those discussions - concepts such as native or indigineous, current euphemisms for the out-dated primitive, civilization or culture, sometimes used interchangeably with race at other times, and theories such as evolutionism. In order to exemplify how different social movements make use of these concepts, the author analyses those political groups who defend the so called foragers and hunters, such as the Inuit in northern Canada or the Bushmen in the south of Africa.

    Full Text Available In this paper, the architectures of three degrees of freedom (3-DoF spatial, fully parallel manipulators (PMs, whose limbs are structurally identical, are obtained systematically. To do this, the methodology followed makes use of the concepts of the displacement group theory of rigid body motion. This theory works with so-called ‘motion generators’. That is, every limb is a kinematic chain that produces a certain type of displacement in the mobile platform or end-effector. The laws of group algebra will determine the actual motion pattern of the end-effector. The structural synthesis is a combinatorial process of different kinematic chains’ topologies employed in order to get all of the 3-DoF motion pattern possibilities in the end-effector of the fully parallel manipulator.

  6. Learning to communicate risk information in groups

    Full Text Available Despite vigorous research on risk communication, little is known about the social forces that drive these choices. Erev, Wallsten, and Neal (1991 showed that forecasters learn to select verbal or numerical probability estimates as a function of which mode yields on average the larger group payoffs. We extend the result by investigating the effect of group size on the speed with which forecasters converge on the better communication mode. On the basis of social facilitation theory we hypothesized that small groups induce less arousal and anxiety among their members than do large groups when performing new tasks, and therefore that forecasters in small groups will learn the better communication mode more quickly. This result obtained in Experiment 1, which compared groups of size 3 to groups of size 5 or 6. To test whether social loafing rather than social facilitation was mediating the effects, Experiment 2 compared social to personal feedback holding group size constant at 3 members. Learning was faster in the personal feedback condition, suggesting that social facilitation rather than loafing underlay the results.

    The centers of psychosocial care (CAPS, acronym in Portuguese) are strategic devices for mental health care currently available in Brazil. Nurses are professionals required to compose the minimum staff of this device, which values the group activities involving users. This study presents a report of the experience of nursing undergraduates from Universidade Federal do Mato Grosso (UFMT) on their conducting waiting-room group sessions with relatives of users of a CAPS from Cuiabá, Mato Grosso state. This experience is justified by the fact that nursing students have few opportunities to develop group approach abilities during their graduation course, which focuses mainly on clinical individual care. The aim of the experience was to provide theoretical-practical learning of all the work stages of group work: recognizing the need and possibility of conducting the activity, planning, coordination and group evaluation. The results confirm the need and possibility of performing group experiences in mental health care and in nursing education.

    Full Text Available This study examined wall ultrastructure variability in the microscopic green alga Pediastrum s.l. Its value as a diagnostic character is discussed. Field and cultured material of 21 taxa were compared using light and scanning electron microscopy. Nine ultrastructural elements occurring on the surface of Pediastrum are documented with LM and SEM micrographs. The highest number of taxa showed reticulate ornamentation composed of a trigonal mesh and granules situated on its corners. The paper considers the use of wall ultrastructure to reconcile traditional and modern taxonomical systems with regard to Pediastrum varieties, and addresses the phylogenetic relationships between strains representing different varieties.

    A qualitative study on species composition and diversity of phytoplankton flora was carried out in the Anjanapura reservoir. Water samples were collected monthly at four sites from November 2005 to October 2007 for plankton analysis. A total of 152 phytoplankton species belonging to 59 genera were recorded. The species belonging to genera Crucigenia, Pediastrum, Scenedesmus, Tetraedron, Cyclotella, Gyrosigma, Melosira, Navicula, Fragillaria, pinnularia, Synedra, Closterium, Cosmarium, Euastrum, Staurastrum, Gleocapsa, Merismopedia, Microcystis, Oscillatoria, Euglena and Phacus were found dominant. Phytoplankton density was recorded in the range of 222-1467 Org l(-1) for chlorococcales, 267-1467 Org I (-1) for diatoms, 44-889 Org l(-1) for desmids, 44-889 Org l(-1) for blue-greens and 22-1667 Org l(-1) for euglenoids. Seasonal density Shannon-Weiner diversity index (1.60-1.88) indicate that reservoir exhibited rich phytoplankton and Nygaard tropic status indices for myxophycean (1.0-1.50), chlorophycean (1.62-2.16), diatoms (0.10-0.14), euglenophycean (0.18-0.19) and compound quotient(3.25-4.66) showed that reservoir was moderately polluted. From the observed data, it could be concluded that the presence of more diverse group of phytoplankton indicate the productivity of the reservoir.

    'Doing good medical ethics' involves attending to both the biomedical and existential aspects of illness. For this, we need to bring in a phenomenological perspective to the clinical encounter, adopt a virtue-based ethic and resolve to re-evaluate the goals of medicine, in particular the alleviation of suffering and the role of compassion in everyday ethics.

    2015-03-01

    This paper is a discussion of the duty of doctors to do what is best for their patients. What is required by this duty is shown to depend on the circumstances, including any financial constraints on the doctor. The duty to do the best is a duty of benevolence, and this virtue itself has to be understood as bounded by other virtues, including justice and professional responsibility. An Aristotelian account of medical benevolence is developed, and the issues of supererogation and individual judgement are discussed within this framework. The paper ends with the claim that the patient-centred conception of benevolence defended in the paper is in line with consequentialist and deontological ethical traditions.

    1986-01-01

    The disposal and siting of hazardous and radioactive wastes has created numerous problems for decision-makers in the field of waste management. The social/political problems have proven to be some of the most difficult to solve. Public knowledge of the presence of hazardous and radioactive waste sites has grown considerably in recent years. Over the same period, the process of choosing new disposal sites has attracted a great deal of publicity. In many cases, when existing sites are discovered or when a community is being considered for a new disposal site, organized groups emerge in the community to support or oppose the proposed actions and the decision-makers responsible. Emergent groups are a form of organized collective action in response to a particular situation or event, such as the siting or discovery of a hazardous waste disposal site. Sociological methods and theory can provide insight on the patterns common to these groups, their emergence, and their survival or decline. The questions addressed in this paper are: what are the variables that lead to the formation of such groups, and what conditions or group actions contribute to their growth and survival?

    Following the risk-need-responsivity (RNR) model, cognitive-behavioral therapy is considered most effective in reducing recidivism when based on dynamic risk factors. As studies have found differences of these factors across age, exploring this seems beneficial. The current study investigates the Central Eight (C8) risk factors across six age groups of outpatient sex offenders ( N = 650). Results showed that recidivism rates and age were inversely related from 19 years and up. Half of the C8 did not predict general recidivism at all, substance abuse, antisocial cognition, antisocial associates, and history of antisocial behavior in only one or several age groups. However, factors differed between age groups, with the youngest group demonstrating the most dysfunction in several areas and the oldest group the least. It is concluded that the C8 risk factors seem to lose significance in the older age groups. Results may benefit targeting treatment goals.

    Group dynamics play a significant role within any organization, culture, or unit. The important thing to remember with any of these structures is that they are made up of people--people with different ideas, motivations, background, and sometimes different agendas. Most groups, formal or informal, look for a leader in an effort to maintain cohesiveness of the unit. At times, that cultural bond must be developed; once developed, it must be nurtured. There are also times that one of the group no longer finds the culture comfortable and begins to act out behaviorally. It is these times that become trying for the leader as she or he attempts to remain objective when that which was once in the building phase of group cohesiveness starts to fall apart. At all times, the manager must continue to view the employee creating the disturbance as an integral part of the group. It is at this time that it is beneficial to perceive the employee exhibiting problem behaviors as a special employee, as one who needs the benefit of your experience and skills, as one who is still part of the group. It is also during this time that the manager should focus upon her or his own views in the area of power, communication, and the corporate culture of the unit that one has established before attempting to understand another's point of view. Once we understand our own motivation and accept ourselves, it is then that we may move on to offer assistance to another. Once we understand our insecurities recognizing staff dysfunction as a symptom of system dysfunction will not be so threatening to the concept of the manager that we perceive ourselves to be. It takes a secure person to admit that she or he favors staff before deciding to do something to change things. The important thing to know is that it can be done. The favored staff can find a new way of relating to others, the special employee can find new modes of behavior (and even find self-esteem in the process), the group can find new ways

In this context, investigations on how exhaled NO concentrations vary in the postoperative period of cardiac surgery will certainly contribute to new clinical findings. OBJECTIVE: The objective of this study was to compare the EBC NO levels in both the pre and postoperative (24 hours periods of cardiac surgery. METHODS: Twenty - eight individuals were divided into three groups: 1 control, 2 coronary artery bypass grafting, and 3 valve surgery. The nitrite (NO2 - levels were measured by chemiluminescence in blood samples and exhaled breath condensate (EBC. Data were analyzed by the Mann - Whitney and Wilcoxon tests. RESULTS: 1 Preoperatively, the EBC NO2 - levels from groups 2 and 3 patients were higher than control individuals; 2 The postoperative (24 hours NO2 - levels in the EBC from group 3 patients were lower compared with preoperative values; 3 The NO2 - levels in the plasma from group 2 patients were lower in the preoperative compared with the postoperative (24h values and; 4 Preoperatively, there was no difference between groups 2 and 3 in terms of plasma NO2 - concentrations. CONCLUSION: These data suggest that NO measurement in EBC is feasible in cardiac surgery patients.INTRODUÇÃO: Estudos mostrando alterações das concentrações de nitrito (NO2 - exalado, com biomarcador de lesão, são raros em pacientes submetidos à cirurgia cardíaca.

Systematic one-day cruises were undertaken aboard a 5 m sail boat equipped with an outboard motor. Applying the focal-group method, information such as geographical position, predominant behavioural patterns, group size, cohesion index and the presence of calves, were registered at every five-minute interval, totalling 198 hours of direct observation of the dolphins. The estuarine dolphin used preferential areas for each behavioural pattern. The mean group size was approximately 29 individuals, and the presence of calves occurred throughout the entire year, but with a significant increase in the warm seasons. The frequency of behavioural patterns and group size varied according to season and time of day, and were strongly associated. The frequency of moving behaviours increased in the cold seasons and along the day. The seasonal variation in the moving behaviours suggest the requirement of a larger area in the cold seasons, probably related to seasonal fluctuations in the abundance of dominant prey items. Higher group sizes were observed while dolphins were foraging. The cohesion index also varied according to the behaviour. Our results showed that group organization and behavioural patterns of this estuarine dolphin population are probably linked to daily and seasonal environment cycles, and also possibly to the condition of being at the furthest southern limit of distribution of the species.A população residente de boto-cinza, Sotalia guianensis (P.J. van Bénéden, 1864, da Baía Norte, Santa Catarina, sul do Brasil, foi estudada de 2000 a 2003.

    The European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) 'Nano Task Force' proposes a Decision-making framework for the grouping and testing of nanomaterials (DF4nanoGrouping) that consists of 3 tiers to assign nanomaterials to 4 main groups, to perform sub-grouping within the main groups and to determine and refine specific information needs. The DF4nanoGrouping covers all relevant aspects of a nanomaterial's life cycle and biological pathways, i.e. intrinsic material and system-dependent properties, biopersistence, uptake and biodistribution, cellular and apical toxic effects. Use (including manufacture), release and route of exposure are applied as 'qualifiers' within the DF4nanoGrouping to determine if, e.g. nanomaterials cannot be released from a product matrix, which may justify the waiving of testing. The four main groups encompass (1) soluble nanomaterials, (2) biopersistent high aspect ratio nanomaterials, (3) passive nanomaterials, and (4) active nanomaterials. The DF4nanoGrouping aims to group nanomaterials by their specific mode-of-action that results in an apical toxic effect. This is eventually directed by a nanomaterial's intrinsic properties. However, since the exact correlation of intrinsic material properties and apical toxic effect is not yet established, the DF4nanoGrouping uses the 'functionality' of nanomaterials for grouping rather than relying on intrinsic material properties alone. Such functionalities include system-dependent material properties (such as dissolution rate in biologically relevant media), bio-physical interactions, in vitro effects and release and exposure. The DF4nanoGrouping is a hazard and risk assessment tool that applies modern toxicology and contributes to the sustainable development of nanotechnological products. It ensures that no studies are performed that do not provide crucial data and therefore saves animals and resources. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights

  10. Oxytocin promotes group-serving dishonesty.

    2014-04-15

    To protect and promote the well-being of others, humans may bend the truth and behave unethically. Here we link such tendencies to oxytocin, a neuropeptide known to promote affiliation and cooperation with others. Using a simple coin-toss prediction task in which participants could dishonestly report their performance levels to benefit their group's outcome, we tested the prediction that oxytocin increases group-serving dishonesty. A double-blind, placebo-controlled experiment allowing individuals to lie privately and anonymously to benefit themselves and fellow group members showed that healthy males (n = 60) receiving intranasal oxytocin, rather than placebo, lied more to benefit their group, and did so faster, yet did not necessarily do so because they expected reciprocal dishonesty from fellow group members. Treatment effects emerged when lying had financial consequences and money could be gained; when losses were at stake, individuals in placebo and oxytocin conditions lied to similar degrees. In a control condition (n = 60) in which dishonesty only benefited participants themselves, but not fellow group members, oxytocin did not influence lying. Together, these findings fit a functional perspective on morality revealing dishonesty to be plastic and rooted in evolved neurobiological circuitries, and align with work showing that oxytocin shifts the decision-maker's focus from self to group interests. These findings highlight the role of bonding and cooperation in shaping dishonesty, providing insight into when and why collaboration turns into corruption.

  11. Legislative vulnerability of minority groups.

    Minorities are in an inferior position in society and therefore vulnerable in many aspects. This study analyzes legislative vulnerability and aims to categorize as "weak" or "strong" the protection conferred by law to the following minorities: elderly, disabled, LGBT, Indians, women, children/ adolescents and black people. In order to do so, it was developed a documental research in 30 federal laws in which legal provisions were searched to protect minorities. Next, the articles were organized in the following categories: civil, criminal, administrative, labor and procedural, to be analyzed afterwards. Legal protection was considered "strong" when there were legal provisions that observed the five categories and "weak" when it did not meet this criterion. It was noted that six groups have "strong" legislative protection, which elides the assertion that minorities are outside the law. The exception is the LGBT group, whose legislative protection is weak. In addition, consecrating rights through laws strengthens the institutional channels for minorities to demand their rights. Finally, it was observed that the legislative protection granted tominorities is not homogeneous but rather discriminatory, and there is an interference by the majority group in the rights regulation of vulnerable groups.

B. fragilis group strains were isolated from 46 (37% of 124 clinical specimens and the source of the samples was: Blood culture (3, intraabdominal infection (27, brain abscess (2, soft tissue infection (17, respiratory sinus (3, pleural aspirate (9, breast abscess (3, surgical infected wound (22, pelvic inflammatory disease (22, chronic otitis media (9 and miscellaneous (7. Intraabdominal and soft tissue infections were responsible for more than half of the clinical isolates. Susceptibility to penicillin, cefoxitin, tetracycline, metronidazole, chloramphenicol and clindamycin was examined. All isolates were susceptible to metronidazole and chloramphenicol. For clindamycin and cefoxitin the resistance rates observed were 21.7% and 10.9% respectively. Susceptibility profiles varied among the different species tested. A total of 37 species of B. fragilis group isolated from intestinal microbiota of individuals who had no antimicrobial therapy for at least 1 month before the sampling was also examined. All strains were also susceptible to chloramphenicol and motronidazole and the resistance rates to clindamycin and cefoxitin were 19.4% and 5.4% respectively. A few institutions, in Brazil, have monitored the antimicrobial susceptibility of B. fragilis group strains isolated from anaerobic infections. The resistance rates to cefoxitin and clindamycin and the variation in susceptibility patterns among the species isolated in this study emphasize the need for monitoring of susceptibility patterns of B. fragilis group organisms isolated, especially at our University Hospitals.Alguns aspectos epidemiológicos e o perfil de sensibilidade a antimicrobianos de amostras do grupo B. fragilis isoladas de espécime clínico e microbiota intestinal humana foram delineados neste

  1. What are mathematicians doing?

    Science.gov (United States)

    Friedman, B

    1966-10-21

    Let me emphasize the point I have been trying to make. The mathematician's playing with the roots of equations, a play which had no practical motivations and almost no possibilities of practical application, led to the recognition of the importance of symmetry and groups. The study of theory of groups led to mathematical discoveries in geometry and differential equations, and finally to prediction of the existence of a new elementary particle. Surely a surprising outcome for the ivory-tower speculations of an impractical mathematician! Despite my professional bias, I must acknowledge that the importance of symmetry was recognized before mathematicians invented the theory of groups. In 1794 William Blake wrote: Tiger, Tiger, burning bright In the forests of the night, What immortal hand or eye Could frame thy fearful symmetry? However, to the mathematicians must be given the credit of recognizing that, to understand symmetry, you must study the theory of groups. I can now answer my original question, What are mathematicians doing? They are trying to make precise the intuitions of poets.

    2017-06-01

    The aim of this study was to determine whether the personality types of dental students and their group dynamics were linked to their problem-based learning (PBL) performance. The Myers-Briggs Type Indicator (MBTI) instrument was used with 263 dental students enrolled in Seoul National University School of Dentistry from 2011 to 2013; the students had participated in PBL in their first year. A four-session PBL setting was designed to analyze how individual personality types and the diversity of their small groups were associated with PBL performance. Overall, the results showed that the personality type of PBL performance that was the most prominent was Judging. As a group became more diverse with its different constituent personality characteristics, there was a tendency for the group to be higher ranked in terms of PBL performance. In particular, the overperforming group was clustered around three major profiles: Extraverted Intuitive Thinking Judging (ENTJ), Introverted Sensing Thinking Judging (ISTJ), and Extraverted Sensing Thinking Judging (ESTJ). Personality analysis would be beneficial for dental faculty members in order for them to understand the extent to which cooperative learning would work smoothly, especially when considering group personalities.

  4. Wetting transitions: A functional renormalization-group approach

    Fisher, D.S.; Huse, D.A.

    1985-01-01

    A linear functional renormalization group is introduced as a framework in which to treat various wetting transitions of films on substrates. A unified treatment of the wetting transition in three dimensions with short-range interactions is given. The results of Brezin, Halperin, and Leibler in their three different regimes are reproduced along with new results on the multicritical behavior connecting the various regimes. In addition, the critical behavior as the coexistence curve is approached at complete wetting is analyzed. Wetting in the presence of long-range substrate-film interactions that fall off as power laws is also studied. The possible effects of the nonlinear terms in the renormalization group are examined briefly and it appears that they do not alter the critical behavior found using the truncated linear renormalization group

    This research investigates the sexuality of trans women (individuals who were assigned male status at birth who currently identify as women), by focusing on the "bodily techniques" (Crossley, 2006) they use in "doing" sexuality. The "doing sexuality" framework not only is modeled after the "doing gender" approach of West and Zimmerman (1987), but also utilizes the idea of "sexual embodiment" to emphasize the agency of trans women as they conceptualize and organize their sexuality in a socially recognized way. This is often difficult as they confront discrimination from medical and legal professionals as well as intimate partners who may find it difficult to adapt to the trans woman's atypical body and conception of gender. However, with a study group of 25 trans women from San Francisco, we found the study participants to be adept at overcoming such hurdles and developing techniques to "do" their sexuality. At the same time, we found trans women's agency constrained by the erotic habitus (Green, 2008) of the wider society. The interplay between innovation and cultural tradition provides an opportunity to fashion a more general model of "doing" sexuality.

    The idea that the focus of educational research should be on results that can inform the practice of teaching has been an implicit assumption for so many years that one would be hard-pressed to trace it back to an individual source. At one time, the people doing such research in STEM disciplines were faculty in schools or colleges of education who focused on K-12 classrooms and looked for ideas, concepts, and principles that would be valid across a range of STEM disciplines. Eventually, this research was done on college- or university-level students, as well, and there was a shift toward what has been called discipline-based educational research (DBER) that looks at the problems associated with the teaching and learning of a given discipline, such as chemistry. This paper will discuss the results of research on problem-solving in chemistry that has been done in our research group, with particular emphasis on the challenges of teaching and learning organic chemistry. The goal of this paper is to show what can happen when one listens carefully to students and begins to appreciate the difference between what we think we have taught and what the students learned. The examples we will use have the potential for convincing those of us who teach chemistry to rethink what we do in our classes to find better ways of helping our students understand the material we are trying to teach. Although this paper will focus on results from the second-year organic chemistry course, similar results have been observed in both inorganic and physical chemistry, as well as biochemistry courses. © 2017 Wiley-VCH Verlag GmbH & Co.

Thus, to domain this technology by the professionals as a background to guide their assistance and managing actions becomes, each day more important. In this updating article, we consider to develop some aspects of theoretical presupposes and group coordinator dilemmas, as well as pointing elements that can help the professionals who have in the group their field of work. The text also approaches the group setting organization, the handling of preview situations, the time administration, the handling of the group conflicts and the power of the group contract. The essence of this text is anchored in the main group coordinator dilemma that is to find the measure adjustment, or either, balance to do interventions on the contents that emerge from the group dynamics, centered in the scientific and emotional contexts which comes from the work with the group. In this interval between theory and practice, the professional and the personal is where we believe is possible to find the balance. In this way, the notion of the group complexity is basic to the coordinator, so that ahead of its singularity it can live the group and everything what emanates from it. Key words: Group Structure; Health Manpower; Sensitivity Training Group; Group Processes.

    Full Text Available This paper presents the composition and functional groups of the phytoplankton from Comprida lagoon, a tropical humic coastal Lagoon located in Southeast Brazil. A total of 28 taxa was found, distributed in eight taxonomic divisions as follows: 26% Heterokontophyta, 21% Chlorophyta, 21% Cyanophyta, 14% Bacillariophyta, 14% Cryptophyta, and 4% Prymnesiophyta. Twenty-three taxa were identified at the specific and infraspecific levels, from which four are new records for Brazil and two for Rio de Janeiro State. Phytoplankton of the Comprida lagoon was comprised of several flagellates, but also eukaryote and prokaryote picoplankton, filamentous cyanobacteria and several diatoms. The biomass was lower than that found in other lacustrine systems, and showed remarkable temporal variability. According to the functional-group approach, the populations formed eight groups: Q, Z, E, N, X3, X2, S1 and Y, most typical of oligo- or mesotrophic systems, tolerant to nutrient deficiency and sensitive to increased pH.Este trabalho apresenta a composição e os grupos funcionais do fitoplâncton da lagoa Comprida, uma lagoa costeira tropical húmica localizada no sudeste brasileiro.

    Full Text Available The Rio Grande do Sul is the largest producer of rice. In the state, rice is conventionally produced in large areas with intensive use of machinery and inputs, which has been associated with environmental impacts. Innovation can help to change this reality. Some initiatives are being developed in recent years trying to adapt the conventional system the global trend of consumption concerned about the environment. An example is the production of organic rice. In this sense, has established itself as objective to identify the groups of organic production in the state of Rio Grande do Sul and the innovations associated with these groups. The research was characterized as qualitative. The current stage of research enabled us to identify the group of producers associated with the Center for Environmental Education and Rice Agroecological Management Group, coordinated the Cooperative Central Settlements of Rio Grande do Sul. Have been identified other producers or groups. As for innovations, the results of the group of producers associated with the Center for Environmental Education and Monitoring are under review.

    为了准确的进行相邻的相干信号源定位,提出了一种基于多重信号分类群延迟(MUSIC-group delay)的改进算法。首先,将空间平滑技术引入到波达方向(DoA)估计当中去除部分相干信号。由于在信号源相邻的情况下子空间算法的性能降低,就结合了 MUSIC-Group Delay算法来区分相邻的信号源,这种方法因为自身的加和性通过 MUSIC 相位谱来计算群延迟函数,从而能估计出相邻的信号源。理论分析和仿真结果表明提出的方法估计相邻的相干信号源比子空间算法更精确,分辨率更高。%In this paper,the closely spaced coherent-source localization is considered,and an improved method based on the group delay of Multiple Signal Classification (MUSIC)is presented.Firstly,we introduce the spatial smoothing technique into direction of arrival (DoA)estimation to get rid of the coherent part of signals.Due to the degraded per-formance of sub-space based methods on the condition of nearby sources,we then utilize the MUSIC-Group Delay algo-rithm to distinguish the closely spaced sources,which can resolve spatially close sources by the use of the group delay function computed from the MUSIC phase spectrum for efficient DoA estimation owing to its spatial additive property. Theoretical analysis and simulation results demonstrate that the proposed approach can estimate the DoA of the coherent close signal sources more precisely and have higher resolution compared with sub-space based methods.

    It is proved that: (1) The Fourier algebra A(G) of a simple Lie group G of real rank at least 2 with finite center does not have a multiplier bounded approximate unit. (2) The reduced C∗-algebra C∗ r of any lattice in a non-compact simple Lie group of real rank at least 2 with finite center does...... not have the completely bounded approximation property.

  1. Do extra-group fertilizations increase the potential for sexual selection in male mammals?

    Science.gov (United States)

    Fertilizations by males outside the social breeding group (extra-group paternity, EGP) are widespread in birds and mammals. EGP is generally proposed to increase male reproductive skew and thereby increase the potential for sexual selection, but the generality of this relationship is unclear. We extracted data from 27 mammals in seven orders and used phylogenetic comparative methods to investigate the influence of EGP and social mating system on measures of inequality in male fertilization success, which are indices of the potential for sexual selection. We find that EGP and social mating system can predict the potential for sexual selection in mammalian populations, but only when considered jointly and not individually. EGP appears to increase the potential for sexual selection but only when the degree of social polygyny is relatively low. When social polygyny is high, EGP appears to result in a more uniform distribution of reproduction and a decrease in the potential for sexual selection. A possible explanation to be investigated is that the phenotype of extra-group fathers differs systematically across social mating systems. Our findings have implications for the use of EGP and social mating system as indices of sexual selection in comparative analyses of trait evolution under sexual selection. © 2017 The Author(s).

    Full Text Available An important property of micelles with particular significance in pharmacy is their ability to increase the solubility of poorly soluble drugs in water, thus increasing their bioavailability. In this work, the solubilization of ibuprofen (IBU was studied in micellar solutions of three surfactants possessing the same hydrocarbon tail but different hydrophilic head groups, namely sodium dodecyl sulphate (SDS, dodecyltrimethylammonium bromide (DTAB, and n-dodecyl octa(ethylene oxide (C12EO8. The results showed that, irrespective of the surfactant type, the solubility of IBU increased linearly with increasing surfactant concentration, as a consequence of the association between the drug and the micelles. The 80 mM DTAB and the 80 mM C12EO8 micellar solutions resulted in a 16-fold increase in solubility of IBU when compared to the buffer solution, whereas the 80 mM SDS micellar solution resulted in a 5.5-fold increase in IBU solubility. The highest value of molar solubilization capacity (chi was obtained with DTAB, chi = 0.97, followed by C12EO8 ,chi = 0.72, and finally SDS, chi = 0.23. However, due to the stronger tendency of the nonionic surfactant in forming micelles in solution, at the same surfactant concentration, we obtained the same solubility of IBU in both DTAB and C12EO8.Uma propriedade importante das micelas, do ponto de vista farmacêutico, refere-se ao potencial destas em solubilizar fármacos pouco solúveis em água, aumentando sua biodisponibilidade.

  11. Solidarity through shared disadvantage: Highlighting shared experiences of discrimination improves relations between stigmatized groups.

    Intergroup relations research has largely focused on relations between members of dominant groups and members of disadvantaged groups. The small body of work examining intraminority intergroup relations, or relations between members of different disadvantaged groups, reveals that salient experiences of ingroup discrimination promote positive relations between groups that share a dimension of identity (e.g., 2 different racial minority groups) and negative relations between groups that do not share a dimension of identity (e.g., a racial minority group and a sexual minority group). In the present work, we propose that shared experiences of discrimination between groups that do not share an identity dimension can be used as a lever to facilitate positive intraminority intergroup relations. Five experiments examining relations among 4 different disadvantaged groups supported this hypothesis. Both blatant (Experiments 1 and 3) and subtle (Experiments 2, 3, and 4) connections to shared experiences of discrimination, or inducing a similarity-seeking mindset in the context of discrimination faced by one's ingroup (Experiment 5), increased support for policies benefiting the outgroup (Experiments 1, 2, and 4) and reduced intergroup bias (Experiments 3, 4, and 5). Taken together, these experiments provide converging evidence that highlighting shared experiences of discrimination can improve intergroup outcomes between stigmatized groups across dimensions of social identity. Implications of these findings for intraminority intergroup relations are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Full text: In his review 'Genesis of Unified Gauge Theories' at the symposium in Honour of Abdus Salam (June, page 23), Tom Kibble of Imperial College, London, looked back to the physics events around Salam from 1959-67. He described how, in the early 1960s, people were pushing to enlarge the symmetry of strong interactions beyond the SU(2) of isospin and incorporate the additional strangeness quantum number. Kibble wrote - 'Salam had students working on every conceivable symmetry group. One of these was Yuval Ne'eman, who had the good fortune and/or prescience to work on SU(3). From that work, and of course from the independent work of Murray Gell- Mann, stemmed the Eightfold Way, with its triumphant vindication in the discovery of the omega-minus in 1964.' Yuval Ne'eman writes - 'I was the Defence Attaché at the Israeli Embassy in London and was admitted by Salam as a part-time graduate student when I arrived in 1958. I started research after resigning from the Embassy in May 1960. Salam suggested a problem: provide vector mesons with mass - the problem which was eventually solved by Higgs, Guralnik, Kibble,.... (as described by Kibble in his article). I explained to Salam that I had become interested in symmetry. Nobody at Imperial College at the time, other than Salam himself, was doing anything in groups, and attention further afield was focused on the rotation - SO(N) - groups. Reacting to my own half-baked schemes, Salam told me to forget about the rotation groups he taught us, and study group theory in depth, directing me to Eugene Dynkin's classification of Lie subalgebras, about which he had heard from Morton Hamermesh. I found Dynkin incomprehensible without first learning about Lie algebras from Henri Cartan's thesis, which luckily had been reproduced by Dynkin in his 1946 thesis, using his diagram method.

  14. Grouped to Achieve: Are There Benefits to Assigning Students to Heterogeneous Cooperative Learning Groups Based on Pre-Test Scores?

    Werth, Arman Karl

    Cooperative learning has been one of the most widely used instructional practices around the world since the early 1980's. Small learning groups have been in existence since the beginning of the human race. These groups have grown in their variance and complexity overtime. Classrooms are getting more diverse every year and instructors need a way to take advantage of this diversity to improve learning. The purpose of this study was to see if heterogeneous cooperative learning groups based on student achievement can be used as a differentiated instructional strategy to increase students' ability to demonstrate knowledge of science concepts and ability to do engineering design. This study includes two different groups made up of two different middle school science classrooms of 25-30 students. These students were given an engineering design problem to solve within cooperative learning groups. One class was put into heterogeneous cooperative learning groups based on student's pre-test scores. The other class was grouped based on random assignment. The study measured the difference between each class's pre-post gains, student's responses to a group interaction form and interview questions addressing their perceptions of the makeup of their groups. The findings of the study were that there was no significant difference between learning gains for the treatment and comparison groups. There was a significant difference between the treatment and comparison groups in student perceptions of their group's ability to stay on task and manage their time efficiently. Both the comparison and treatment groups had a positive perception of the composition of their cooperative learning groups.

  15. Computing group cardinality constraint solutions for logistic regression problems.

    We derive an algorithm to directly solve logistic regression based on cardinality constraint, group sparsity and use it to classify intra-subject MRI sequences (e.g. cine MRIs) of healthy from diseased subjects. Group cardinality constraint models are often applied to medical images in order to avoid overfitting of the classifier to the training data. Solutions within these models are generally determined by relaxing the cardinality constraint to a weighted feature selection scheme. However, these solutions relate to the original sparse problem only under specific assumptions, which generally do not hold for medical image applications. In addition, inferring clinical meaning from features weighted by a classifier is an ongoing topic of discussion. Avoiding weighing features, we propose to directly solve the group cardinality constraint logistic regression problem by generalizing the Penalty Decomposition method. To do so, we assume that an intra-subject series of images represents repeated samples of the same disease patterns. We model this assumption by combining series of measurements created by a feature across time into a single group. Our algorithm then derives a solution within that model by decoupling the minimization of the logistic regression function from enforcing the group sparsity constraint. The minimum to the smooth and convex logistic regression problem is determined via gradient descent while we derive a closed form solution for finding a sparse approximation of that minimum. We apply our method to cine MRI of 38 healthy controls and 44 adult patients that received reconstructive surgery of Tetralogy of Fallot (TOF) during infancy. Our method correctly identifies regions impacted by TOF and generally obtains statistically significant higher classification accuracy than alternative solutions to this model, i.e., ones relaxing group cardinality constraints.

    The ab-initio density matrix renormalization group (DMRG) is a tool that can be applied to a wide variety of interesting problems in quantum chemistry. Here, we examine the density matrix renormalization group from the vantage point of the quantum chemistry user. What kinds of problems is the DMRG well-suited to? What are the largest systems that can be treated at practical cost? What sort of accuracies can be obtained, and how do we reason about the computational difficulty in different molecules? By examining a diverse benchmark set of molecules: π-electron systems, benchmark main-group and transition metal dimers, and the Mn-oxo-salen and Fe-porphine organometallic compounds, we provide some answers to these questions, and show how the density matrix renormalization group is used in practice.

    Social transmission of information is vital for many group-living animals, allowing coordination of motion and effective response to complex environments. Revealing the interaction networks underlying information flow within these groups is a central challenge. Previous work has modeled interactions between individuals based directly on their relative spatial positions: each individual is considered to interact with all neighbors within a fixed distance (metric range), a fixed number of nearest neighbors (topological range), a 'shell' of near neighbors (Voronoi range), or some combination (Figure 1A). However, conclusive evidence to support these assumptions is lacking. Here, we employ a novel approach that considers individual movement decisions to be based explicitly on the sensory information available to the organism. In other words, we consider that while spatial relations do inform interactions between individuals, they do so indirectly, through individuals' detection of sensory cues. We reconstruct computationally the visual field of each individual throughout experiments designed to investigate information propagation within fish schools (golden shiners, Notemigonus crysoleucas). Explicitly considering visual sensing allows us to more accurately predict the propagation of behavioral change in these groups during leadership events. Furthermore, we find that structural properties of visual interaction networks differ markedly from those of metric and topological counterparts, suggesting that previous assumptions may not appropriately reflect information flow in animal groups.

    2012-11-01

    Full Text Available This study has the objective to describe the reasons that take the aged ones to practice physical activities in the Third Age Groups and the barriers that hinder them. Thirty aged citizens were subject of this research. The methodological approaching was an exploratory descriptive study, in witch was applied a questionnaire about motivation and barriers for the physical activity practice. As result, it was evidenced that the motivation of the aged ones for physical activity practice is related to: To congregate and meet with other people; to feel itself carried through; to feel themselves mentally more alert and to improve and keep the health. As for the barriers, they exist, in diverse aspects: social, physical and psychic. Although they exist, for these aged ones it did not became something that completely hindered them to go to the group and to practice physical activities. In conclusion, although the difficulties that the aged ones find day after day, the motivation and the barriers are related to the perception of each one, which can become an important and definitive factor for the assiduity or desistance of these individuals in the third age group.

    The prevalence of chronic disease and do-not-intubate status increases with age. Thus, we aimed to determine characteristics and outcomes associated with noninvasive ventilation (NIV) use for acute respiratory failure (ARF) in different age groups. A database comprising prospective data collected on site on all adult patients with ARF requiring ventilatory support from 8 acute care hospitals in Massachusetts was used. From a total of 1,225 ventilator starts, overall NIV utilization, success, and in-hospital mortality rates were 22, 54, and 18% in younger (18-44 y); 34, 65, and 13% in middle-aged (45-64 y); 49, 68, and 17% in elderly (65-79 y); and 47, 76, and 24% in aged (≥ 80 y) groups, respectively (P age (25, 57, 57, and 74% and 7, 12, 18, and 31%, respectively, in the 4 age groups [P age groups (P = .27 and P = .98, respectively). NIV use and a do-not-intubate status are more frequent in subjects with ARF ≥ 65 y than in those age groups. (ClinicalTrials.gov registration NCT00458926.). Copyright © 2016 by Daedalus Enterprises.

    Ethnic group discrimination represents a notable risk factor that may contribute to mental health problems among ethnic minority college students. However, cultural resources (e.g., ethnic identity) may promote psychological adjustment in the context of group-based discriminatory experiences. In the current study, we examined the associations between perceptions of ethnic group discrimination and depressive symptoms, and explored dimensions of ethnic identity (i.e., exploration, resolution, and affirmation) as mediators of this process among 2,315 ethnic minority college students (age 18 to 30 years; 37% Black, 63% Latino). Results indicated that perceived ethnic group discrimination was associated positively with depressive symptoms among students from both ethnic groups. The relationship between perceived ethnic group discrimination and depressive symptoms was mediated by ethnic identity affirmation for Latino students, but not for Black students. Ethnic identity resolution was negatively and indirectly associated with depressive symptoms through ethnic identity affirmation for both Black and Latino students. Implications for promoting ethnic minority college students' mental health and directions for future research are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

    2016-12-01

    The aim of the study was to describe and to understand midwives' and child healthcare nurses' experiences of working with parent education groups through their descriptions of the role and what they find rewarding and challenging in that work. Data were collected through three open-ended questions from a web survey: 'How do you refer to your role when working in parent education?', 'What is the biggest challenge or difficulty for you when working in parent education?' and 'What is most rewarding when working in parent education?' The answers were analysed by using qualitative content analysis and correlation analysis. The results show that the midwives and child healthcare nurses either included or excluded the group when describing their role as leaders and their influence on parents. The same applies to what they found rewarding and what was difficult and challenging for them in working with the groups. Primarily, the leaders who excluded the group expressed a lack of competence on a professional level in managing groups and using the right teaching methods to process the knowledge content. One important question to deal with is how to best support midwives and nurses in child healthcare to be prepared for working with parent education groups. One obvious thing is to provide specialized training in an educational sense. An important aspect could also be providing supervision, individually or in groups. © The Author 2015.

    Pain is a subjectively complex and universal experience. We examine research investigating ethnic group differences in experimental pain response and factors contributing to group differences. We conducted a systematic literature review and analysis of studies using experimental pain stimuli to assess pain sensitivity across multiple ethnic groups. Our search covered the period from 1944 to 2011, and used the PubMed bibliographic database; a reference source containing over 17 million citations. We calculated effect sizes; identified ethnic/racial group categories, pain stimuli, and measures; and examined findings regarding biopsychosociocultural factors contributing to ethnic/racial group differences. We found 472 studies investigating ethnic group differences and pain. Twenty-six of these met our review inclusion criteria of investigating ethnic group differences in experimental pain. The majority of studies included comparisons between African Americans (AA) and non-Hispanic Whites (NHW). There were consistently moderate to large effect sizes for pain tolerance across multiple stimulus modalities; AA demonstrated lower pain tolerance. For pain threshold, findings were generally in the same direction, but effect sizes were small to moderate across ethnic groups. Limited data were available for suprathreshold pain ratings. A subset of studies comparing NHW and other ethnic groups showed a variable range of effect sizes for pain threshold and tolerance. There are potentially important ethnic/racial group differences in experimental pain perception. Elucidating ethnic group differences has translational merit for culturally competent clinical care and for addressing and reducing pain treatment disparities among ethnically/racially diverse groups.

    Full Text Available The Synthetic Sentence Identification (SSI test assesses central auditory pathways by measuring auditory and visual sensitivity and testing selective attention. Cerebellum activation in auditory attention and sensorial activity modulation have already been described. Assessing patients with cerebellar lesions alone using the SSI test can confirm the role of the cerebellum in auditory processing. AIM: To evaluate the role of the cerebellum in auditory processing in individuals with normal hearing and in those with chronic cerebellum lesions, using the SSI test. MATERIALS AND METHODS: Cross-sectional cohort study. A study group comprising 18 patients with chronic cerebellar lesion and a control group of 20 healthy individuals were assessed. The SSI test was applied in an Ipsilateral Competitive Message (ICM and Contralateral Competitive Message (CCM modes. To compare the results between groups, we used the chi-square test for qualitative variables. RESULTS: A statistically significant difference was found between the study and control groups using the ICM mode of the SSI test (p=0.035, but not in the CCM mode (p=0.083. CONCLUSION: The results on the SSI confirmed cerebellar participation in auditory processing in individuals with chronic cerebellar lesions and in those with normal hearing assessed in this study.O teste de Identificação de Sentenças Sintéticas (SSI avalia as vias centrais da audição utilizando a sensibilidade auditiva e visual e testando a atenção seletiva. A ativação do cerebelo na atenção auditiva, assim como na modulação da atividade sensorial, já é descrita. Avaliar pacientes com lesão exclusiva do cerebelo por meio do teste SSI pode confirmar ou refutar a hipótese da participação do cerebelo no processamento auditivo. OBJETIVO: Avaliar pelo teste SSI a participação do cerebelo no processamento auditivo, em indivíduos com lesão crônica do cerebelo e audição normal. MATERIAL E MÉTODOS: Estudo coorte

    Full Text Available OBJETIVOS: Descrever aspectos metodológicos e resultados preliminares de um estudo de intervenção planejado para medir o impacto de um programa de suplementação alimentar sobre a promoção do crescimento infantil de crianças desnutridas. MÉTODOS: Estudo longitudinal, controlado, desenvolvido no estado de Alagoas, com grupos comparados antes e depois da intervenção. Vinte municípios foram selecionados através de um indicador de cobertura do programa de suplementação alimentar. Essa cobertura foi estimada pela diferença entre a proporção de crianças desnutridas e a proporção de crianças atendidas pelo programa. Os dez municípios com indicador de alta cobertura foram selecionados para o grupo intervenção e aqueles de menor cobertura para o grupo controle. Em cada município do grupo intervenção foram selecionadas 15 crianças ingressando no Programa. Em cada município do grupo controle foram incluídas 15 crianças elegíveis, mas que não conseguiram vaga no Programa. RESULTADOS: Foram aplicados 111 e 102 questionários em crianças dos municípios do grupo intervenção e controle, respectivamente. A comparação em relação às características de base mostra que a distribuição das variáveis demográficas e nutricionais foi semelhante entre as crianças dos grupos intervenção e controle. Por outro lado, as crianças do grupo intervenção são provenientes de famílias com menor renda familiar e seus pais apresentaram menor escolaridade quando comparadas às do grupo controle. CONCLUSÕES: Os resultados preliminares mostram que os grupos são comparáveis em relação às variáveis demográficas e nutricionais e que as diferenças observadas quanto ao nível socioeconômico deverão ser consideradas na análise ajustada, na segunda fase do estudo.OBJECTIVE: To describe methodological aspects and preliminary results of an intervention designed to measure the impact on child growth of nutritional programs

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n2p224   The aim of the study was to analyze the effect of a tapering period on anaerobic power and capacity of tae-kwon-do athletes. Thirty-one male tae-kwon-do participants of the Brazilian Championship were selected in a non-probabilistic way. Subjects were randomly divided into two groups, namely: experimental group (EG, n = 15 and control group (CG, n = 17. Both groups followed the same training protocol up to the tapering stage. CG was submitted to training loads contained in the last two weeks of the macrocycle. Only EG was submitted to tapering. Tapering had 2 weeks duration, adopting the linear tapering method. Taekwondo Anaerobic Test was performed by athletes before the start of the season, which was named as pre-intervention, and the last week of each mesocycle [Prep I, Prep II and Tapering (only EG]. Group vs. time effect interaction (p < 0.01 was identified for alactic anaerobic power, with an increase only in EG in tapering (p = 0.01. A significant group vs. time interaction (p <0.01 was revealed to fatigue index, improved anaerobic capacity being checked in EG only after the tapering period (p = 0.01. It was concluded that two weeks of linear type tapering optimized the anaerobic power and capacity of male tae-kwon-do athletes.

  17. Asymptotical representation of discrete groups

    Mishchenko, A.S.; Mohammad, N.

    1995-08-01

    If one has a unitary representation ρ: π → U(H) of the fundamental group π 1 (M) of the manifold M then one can do may useful things: 1. To construct a natural vector bundle over M; 2. To construct the cohomology groups with respect to the local system of coefficients; 3. To construct the signature of manifold M with respect to the local system of coefficients; and others. In particular, one can write the Hirzebruch formula which compares the signature with the characteristic classes of the manifold M, further based on this, find the homotopy invariant characteristic classes (i.e. the Novikov conjecture). Taking into account that the family of known representations is not sufficiently large, it would be interesting to extend this family to some larger one. Using the ideas of A.Connes, M.Gromov and H.Moscovici a proper notion of asymptotical representation is defined. (author). 7 refs

    2013-01-01

    Flocking behaviour, as a type of self-organised collective behaviour, is described as the spatial formation of groups without global control and explicit inter-individual recruitment signals. It can be observed in many animals, such as bird flocks, shoals or herds of ungulates. Spatial attraction between humans as the central component of flocking behaviour has been simulated in a number of seminal models but it has not been detected experimentally in human groups so far. The two other sub-processes of this self-organised collective movement - collision avoidance and alignment - are excluded or held constant respectively in this study. We created a computer-based, multi-agent game where human players, represented as black dots, moved on a virtual playground. The participants were deprived of social cues about each other and could neither communicate verbally nor nonverbally. They played two games: (1) Single Game, where other players were invisible, and (2) Joint Game, where each player could see players' positions in a local radius around himself/herself. We found that individuals approached their neighbours spontaneously if their positions were visible, leading to less spatial dispersion of the whole group compared to moving alone. We conclude that human groups show the basic component of flocking behaviour without being explicitly instructed or rewarded to do so. Copyright © 2012 Elsevier B.V. All rights reserved.

    legalidade do aborto no Brasil, aliado a uma tendência favorável à ampliação do permissivo legal para outras situações não previstas em lei. Ressalta-se a importância da inclusão dessa temática nos currículos de graduação e do desenvolvimento de estratégias de ensino interprofissional.PURPOSE: To analyze and compare the knowledge and opinions of Law and Medical students regarding the issue of abortion in Brazil. METHODS: This was a cross-sectional study involving 125 graduate students from the class of 2010. Of these, 52 were medical students (MED group and 73 law students (LAW group. A questionnaire was applied based on published research about the topic. Dependent variables were: monitoring the abortion debate, knowledge concerning situations where abortion is permitted under Brazilian law, opinion about situations that agree with extending legal permission to terminate pregnancy and prior knowledge of someone who has undergone induced abortion. Independent variables were: sex, age, household income and graduation course. Statistical analysis: χ² and Fisher's exact tests, with the level of significance set at 5%. RESULTS: Most interviewees reported monitoring the debate on abortion in Brazil (67.3% of the MED group and 70.2% of the LAW group, p>0.05.

    Full Text Available The recent material published in the press concerning Northeast region of Brazil (Nordeste shows a direct association between the region’s low levels of social and economic development and its semi-arid nature. This perspective reveals a deterministic treatment of the matter. This article investigates both the origins and the avatars of such a deterministic view based on the works of the members of Instituto do Ceará, created in 1887. The analysis of this material has shown that, in the late nineteenth and early twentieth centuries, a group of authors emphasized the climate as a conditioning factor to the region’s progress. During the same period, another set of articles describes the previous periods of drought ("secas" accentuating their tragic aspects. Yet they do not establish any direct relationship between the climate and the region’s poverty or wealth. In the first half of this century these views were overwhelmed by another one, that identifies the environment and the aridness as the causes of the region’s underdevelopment. Since then, this last one has become the hegemonic

    This is a descriptive-exploratory study using a qualitative approach, conducted in ten municipalities in southern Brazil. Data were obtained by talking to 21 nurses from February to November 2012, through semi-structured interviews using questions to probe their health promotion practices. Data were analyzed through thematic analysis focused on health promotion concepts. We identified four themes about health promotion practices of family health nurses in Brazil: a) training of nurses for health promotion practice was weak; b) nurses formed health promotion groups around diseases and life stages; c) nurses formed groups to meet community needs; and d) nurses used health promotion techniques in group work. These family health nurses were somewhat aware of the importance of health promotion, and how to assist the population against various ailments using some health promotion strategies. The main weaknesses were the lack of understanding about health promotion concepts, and the difficulty of understanding the relevance of its practice, probably attributable to limitations in training. We conclude that primary care groups in Brazil's unified health system could do better in applying health promotion concepts in their practice.

     The aim of this study was to assess methods used to access target groups in prevention projects funded within the prevention research framework by the German Federal Ministry of Education and Research.  A survey with prevention projects was conducted. Access strategies, communication channels, incentives, programme reach, and successful practical recruitment strategies were explored.  38 out of 60 projects took part in the survey. Most projects accessed their target group within structured settings (e. g., child day-care centers, schools, workplaces). Multiple communication channels and incentives were used, with written information and monetary incentives being used most frequently. Only few projects were able to report their programme reach adequately; programme reach was highest for programmes accessing the target groups in structured settings. The respondents viewed active recruitment via personal communication with the target group and key persons in the settings as the most successful strategy.  The paper provides an overview on recruitment strategies used in current preven-tion projects. More systematic research on programme reach is necessary. © Georg Thieme Verlag KG Stuttgart · New York.

  6. STATISTICAL TOOLS FOR CLASSIFYING GALAXY GROUP DYNAMICS

    2009-01-01

    The dynamical state of galaxy groups at intermediate redshifts can provide information about the growth of structure in the universe. We examine three goodness-of-fit tests, the Anderson-Darling (A-D), Kolmogorov, and χ 2 tests, in order to determine which statistical tool is best able to distinguish between groups that are relaxed and those that are dynamically complex. We perform Monte Carlo simulations of these three tests and show that the χ 2 test is profoundly unreliable for groups with fewer than 30 members. Power studies of the Kolmogorov and A-D tests are conducted to test their robustness for various sample sizes. We then apply these tests to a sample of the second Canadian Network for Observational Cosmology Redshift Survey (CNOC2) galaxy groups and find that the A-D test is far more reliable and powerful at detecting real departures from an underlying Gaussian distribution than the more commonly used χ 2 and Kolmogorov tests. We use this statistic to classify a sample of the CNOC2 groups and find that 34 of 106 groups are inconsistent with an underlying Gaussian velocity distribution, and thus do not appear relaxed. In addition, we compute velocity dispersion profiles (VDPs) for all groups with more than 20 members and compare the overall features of the Gaussian and non-Gaussian groups, finding that the VDPs of the non-Gaussian groups are distinct from those classified as Gaussian.

    We give a complete description of distributions that are asymptotically homogeneous (including the case of critical index of the asymptotic scale) along the trajectories determined by continuous multiplicative one-parameter transformation groups such that the real parts of all eigenvalues of the infinitesimal matrix are positive. To do this, we introduce and study special spaces of distributions. As an application of our results, we describe distributions that are homogeneous along such groups.

  15. Pride, Shame, and Group Identification.

    Salice, Alessandro; Montes Sánchez, Alba

    2016-01-01

    Self-conscious emotions such as shame and pride are emotions that typically focus on the self of the person who feels them. In other words, the intentional object of these emotions is assumed to be the subject that experiences them. Many reasons speak in its favor and yet this account seems to leave a question open: how to cash out those cases in which one genuinely feels ashamed or proud of what someone else does? This paper contends that such cases do not necessarily challenge the idea that shame and pride are about the emoting subject. Rather, we claim that some of the most paradigmatic scenarios of shame and pride induced by others can be accommodated by taking seriously the consideration that, in such cases, the subject "group-identifies" with the other. This is the idea that, in feeling these forms of shame or pride, the subject is conceiving of herself as a member of the same group as the subject acting shamefully or in an admirable way. In other words, these peculiar emotive responses are elicited in the subject insofar as, and to the extent that, she is (or sees herself as being) a member of a group - the group to which those who act shamefully or admirably also belong. By looking into the way in which the notion of group identification can allow for an account of hetero-induced shame and pride, this paper attempts to achieve a sort of mutual enlightenment that brings to light not only an important and generally neglected form of self-conscious emotions, but also relevant features of group identification. In particular, it generates evidence for the idea that group identification is a psychological process that the subject does not have to carry out intentionally in the sense that it is not necessarily triggered by the subject's conative states like desires or intentions.

    Three propositions that are central to J. R. Harris's group socialization theory (1995, 1998) are considered in this review. These propositions are as follows: (a) Parental behaviors have no long-term effects on children's psychological characteristics, (b) peer groups are the primary environmental influence on psychological functioning, and (c) dyadic relationships are situation-specific and do not generalize. The evidence that J. R. Harris has outlined in support of each of these propositions is reviewed, as is additional empirical research not considered by J. R. Harris. Serious limitations to each proposition are identified. The available evidence is more consistent with a model of multiple socialization agents. An expanded research agenda that permits a more definitive test of J. R. Harris's propositions and social relationship theory is proposed.

    Full Text Available This investigation evaluated the burn process in prehistoric ceramic from the Serra do Evaristo I, an archaeological site, located in Baturité, Ceará, in Northeast Brazil. The material analysis shows variation in the material coloration that can indicate different burning processes. However, in a prehistoric and ethno-historic context of the groups from the Brazilian northeast, the usual data shows only the burning process in an oxidant atmosphere. Therefore, there remains a question concerning whether this variation is related to different production processes of the ceramic material or to the different types of the clays. With the objective of clarifying this question, X-Ray Diffractometry (RXD petrographic analysis were performed on the material. It was verified and shown that the Serra do Evaristo I ceramists used two types of clays originating from two different places and that they could mix the two clay minerals according to the type of vessels that were produced.

    Full Text Available Mundurukú, a Tupian language of Brazil, exhibits two opposite scenarios. On one extreme, there is Mundurukú do Pará, the language of daily communication in the Mundurukú Indigenous Land, with fluent speakers found across all generations and still acquired by children as a mother tongue. On the other extreme, there is Mundurukú do Amazonas, formerly spoken in the Kwatá-Laranjal Indigenous Land, but whose inhabitants have shifted to Portuguese. A group of Mundurukú students from Amazonas decided to initiate a process of language revitalisation as a way to strengthen the community's ethnic and cultural identity. This paper reports the initial stages of language planning, and includes future actions to promote language use in the homes and communities, assessement of language proficiency, and definition of educational programs to teach Mundurukú in local schools.Mundurukú, uma língua Tupí do Brasil, apresenta dois cenários opostos.

    Full Text Available Relevant others (e.g., fellow group members influence how goals and goal-directed behaviors are construed and valued. In turn, according to the “expectancy × value” model of motivated behavioral choice, people engage in goal-directed behaviors when they expect success and ascribe high values to a certain task. In this pilot study, we combine predictions from a social psychological goal perspective with recent theoretical developments from educational psychology, testing the processes that link a person’s social identity with the effort for the achievement goals. With a pilot study using a sample of 86 university students, we tested the assumption that expectation for success and subjective task values mediate the relation between the student identity and effort intentions. In line with our expectations, stronger identification with the group of students was related to stronger effort intentions, mediated via interest and attainment value. These results suggest that social identity may have a profound impact on the engagement decisions made in educational settings.

    The majority of invasive meningococcal disease (IMD) in the developed world is caused by capsular group B Neisseria meningitidis, however success with vaccination against organisms bearing this capsule has previously been restricted to control of geographically limited clonal outbreaks. As we enter a new era, with the first routine program underway to control endemic group B meningococcal disease for infants in the UK, it is timely to review the key landmarks in group B vaccine development, and discuss the issues determining whether control of endemic group B disease will be achieved. Evidence of a reduction in carriage acquisition of invasive group B meningococcal strains, after vaccination among adolescents, is imperative if routine immunization is to drive population control of disease beyond those who are vaccinated (i.e. through herd immunity). The need for multiple doses to generate a sufficiently protective response and reactogenicity remain significant problems with the new generation of vaccines. Despite these limitations, early data from the UK indicate that new group B meningococcal vaccines have the potential to have a major impact on meningococcal disease, and to provide new insight into how we might do better in the future.

    2011-06-01

    We conducted a conversation analysis of 21 threads initiated by newcomers of an online support group (OSG) on eating disorders, to examine the discursive process of entering such a group. The analysis revealed three important issues. First, many newcomers articulate that the step to join the group is extremely difficult. Second, a presentation of the self in terms of a diagnosis works as a legitimization for joining the forum. The data suggest that participants who do not fulfil the conditions for such a legitimization do not join the forum. Third, the option of acquiring a serious symptom as a solution to the legitimization problem is offered by one of the regular members. Hence, the newcomers' discourse reveals issues relevant to the accessibility for undiagnosed sufferers. We discuss these findings theoretically as a phenomenon of self-presentation in relation to community norms. The analysis generates the hypothesis that newcomers are confronted with implicit norms regarding membership legitimacy that they should obey in their self-presentation, although they may not be ready yet to actually do so. OSGs should find strategies to facilitate various possibilities for newcomers to present themselves to the group while becoming a member.

  13. Addiction, agency, and the politics of self-control: doing harm reduction in a heroin users' group.

    2012-04-01

    Our 2007-2009 ethnography describes and analyses the practice of harm reduction in a heroin users' group in the midwestern United States. While dominant addiction interventions conceptualize the addict as powerless - either through moral or physical weakness - this group contested such "commonsense," treating illicit drug use as one of many ways that modern individuals attempt to "fill the void." Insisting on the destigmatization of addiction and the normalization of illicit drug use, the group helped its members work on incremental steps toward self-management. Although "Connection Points" had very limited resources to improve the lives of its members, our work suggests that the users' group did much to restore self-respect, rational subjectivity, and autonomy to a group historically represented as incapable of reason and self-control. As the users cohered as a community, they developed a critique of the oppressions suffered by "junkies," discussed their rights and entitlements, and even planned the occasional political action. Engaging with literature on the cultural construction of agency and responsibility, we consider, but ultimately complicate, the conceptualization of needle exchange as a "neoliberal" form of population management. Within the context of the United States' War on Drugs, the group's work on destigmatization, health education, and the practice of incremental control showed the potential for reassertions of social citizenship within highly marginal spaces.

    Full Text Available The most recent massage therapy (MT study by Hernandez-Reif et al. displays flaws persistent in this area of research that are attributable to MT researchers’ frequent mistake of using within-group analyses of dependent variables in studies that are purported to be randomized control trials. This practise violates the logic of using randomization to create treatment and control groups, and thereby fails to control for the validity threats of spontaneous remission, placebo effects, and statistical regression. The result is that a clear understanding of what MT can and cannot do is seriously hampered.

  16. Dynamical theory of dense groups of galaxies

    Science.gov (United States)

    Mamon, Gary A.

    1990-01-01

    It is well known that galaxies associate in groups and clusters. Perhaps 40% of all galaxies are found in groups of 4 to 20 galaxies (e.g., Tully 1987). Although most groups appear to be so loose that the galaxy interactions within them ought to be insignificant, the apparently densest groups, known as compact groups appear so dense when seen in projection onto the plane of the sky that their members often overlap. These groups thus appear as dense as the cores of rich clusters. The most popular catalog of compact groups, compiled by Hickson (1982), includes isolation among its selection critera. Therefore, in comparison with the cores of rich clusters, Hickson's compact groups (HCGs) appear to be the densest isolated regions in the Universe (in galaxies per unit volume), and thus provide in principle a clean laboratory for studying the competition of very strong gravitational interactions. The $64,000 question here is then: Are compact groups really bound systems as dense as they appear? If dense groups indeed exist, then one expects that each of the dynamical processes leading to the interaction of their member galaxies should be greatly enhanced. This leads us to the questions: How stable are dense groups? How do they form? And the related question, fascinating to any theorist: What dynamical processes predominate in dense groups of galaxies? If HCGs are not bound dense systems, but instead 1D change alignments (Mamon 1986, 1987; Walke & Mamon 1989) or 3D transient cores (Rose 1979) within larger looser systems of galaxies, then the relevant question is: How frequent are chance configurations within loose groups? Here, the author answers these last four questions after comparing in some detail the methods used and the results obtained in the different studies of dense groups.

  17. Are There Limits to Collectivism? Culture and Children's Reasoning About Lying to Conceal a Group Transgression.

    This study explored the effects of collectivism on lying to conceal a group transgression. Seven-, 9-, and 11-year-old US and Chinese children (N = 374) were asked to evaluate stories in which protagonists either lied or told the truth about their group's transgression and were then asked about either the protagonist's motivations or justification for their own evaluations. Previous research suggests that children in collectivist societies such as China find lying for one's group to be more acceptable than do children from individualistic societies such as the United States. The current study provides evidence that this is not always the case: Chinese children in this study viewed lies told to conceal a group's transgressions less favourably than did US children. An examination of children's reasoning about protagonists' motivations for lying indicated that children in both countries focused on an impact to self when discussing motivations for protagonists to lie for their group. Overall, results suggest that children living in collectivist societies do not always focus on the needs of the group.

    Through art, music, and drama children can creatively express the feelings of sadness and anger that occur when a family member dies. In so doing, they can often avoid later difficulties resulting from unresolved emotions. Hospices may want to develop an art therapy group to facilitate this process with clients and their families.

  7. Direct fitness benefits and kinship of social foraging groups in an Old World tropical babbler

    2018-01-01

    Molecular studies have revealed that social groups composed mainly of nonrelatives may be widespread in group-living vertebrates, but the benefits favoring such sociality are not well understood. In the Old World, birds often form conspecific foraging groups that are maintained year-round and offspring usually disperse to other social groups. We tested the hypothesis that nonbreeding group members are largely unrelated and gain direct fitness benefits through breeding opportunities (males) and brood parasitism (females) in the tropical gray-throated babbler, Stachyris nigriceps, in Malaysian Borneo. Babblers foraged in social groups containing one or more breeding pairs (median = 8 group members of equal sex ratio), but group members rarely assisted with breeding (9% of 67 breeding pairs had a third helper; exhibiting facultative cooperative breeding). Although 20% of 266 group member dyads were first-order relatives of one or both members of the breeding pairs, 80% were unrelated. Male group members gained direct fitness benefits through extrapair and extra-group paternity (25% of 73 offspring), which was independent of their relatedness to the breeding pair and increased with decreasing group size. In contrast, females did not gain direct fitness benefits through brood parasitism. The low levels of relatedness and helping in social groups suggest that most group members do not gain indirect fitness benefits by helping to raise unrelated offspring. These findings highlight the importance of examining benefits of sociality for unrelated individuals that largely do not help and broaden the direct fitness benefits of group foraging beyond assumed survival benefits.

    Full Text Available RESUMO: A exposição ao ruído de baixa frequência (RBF (≤500 Hz, incluindo os infra-sons provoca lesões no epitélio do aparelho respiratório. Em ratos cuja gestação ocorreu sob o efeito de RBF, e que subsequentemente passaram um ano em silêncio, observaram-se lesões estabilizadas e definitivas do epitélio respiratório. Neste estudo, investigam-se as lesões que se observam em ratos nascidos em RBF e expostos a RBF adicional. Ratos nascidos em RBF foram posteriormente expostos a RBF adicional antes de serem sacrificados: 145 h (Grupo A, 235 h (Grupo B, 2213 h (Grupo C, 2438 h (GroupD, 4399 h (Grupo E e 5304 h (Grupo F.

    Collaborative inhibition is often observed for both correct and false memories. However, research examining the mechanisms by which collaborative inhibition occurs, such as retrieval disruption, reality monitoring, or group filtering, is lacking. In addition, the creation of the nominal groups (i.e., groups artificially developed by combining individuals' recall) necessary for examining collaborative inhibition do not use statistical best practices. Using the Deese-Roediger-McDermott paradigm, we examined percentages of correct and false memories in individuals, collaborative interactive groups, and correctly created nominal groups, as well as the processes that the collaborative interactive groups used to determine which memories to report. Results showed evidence of the collaborative inhibition effect. In addition, analyses of the collaborative interactive groups' discussions found that these groups wrote down almost all presented words but less than half of nonpresented critical words, after discussing them, with nonpresented critical words being stated to the group with lower confidence and rejected by other group members more often. Overall, our findings indicated support for the group filtering hypothesis.

  17. Exaggerating Accessible Differences: When Gender Stereotypes Overestimate Actual Group Differences.

    Stereotypes are often presumed to exaggerate group differences, but empirical evidence is mixed. We suggest exaggeration is moderated by the accessibility of specific stereotype content. In particular, because the most accessible stereotype contents are attributes perceived to differ between groups, those attributes are most likely to exaggerate actual group differences due to regression to the mean. We tested this hypothesis using a highly accessible gender stereotype: that women are more socially sensitive than men. We confirmed that the most accessible stereotype content involves attributes perceived to differ between groups (pretest), and that these stereotypes contain some accuracy but significantly exaggerate actual gender differences (Experiment 1). We observe less exaggeration when judging less accessible stereotype content (Experiment 2), or when judging individual men and women (Experiment 3). Considering the accessibility of specific stereotype content may explain when stereotypes exaggerate actual group differences and when they do not.

    Full Text Available O presente estudo tem como objetivo analisar, por meio da técnica do Grupo Focal, o entendimento de adolescentes em relação à saúde bucal. A pesquisa foi realizada em três escolas públicas da cidade de Araçatuba, Estado de São Paulo, com dez alunos em cada uma delas. Para a realização dos grupos focais foram abordadas as seguintes palavras, presentes em perguntas de questionários sobre saúde bucal, as quais apresentaram altos índices de erros: saúde bucal; placa bacteriana; dente permanente; flúor; gengiva sangra?; fio dental; transmissão da cárie. Durante as discussões dos grupos focais, observou-se que muitos adolescentes ficavam surpresos com a situação a qual foram submetidos e com o tema que estavam discutindo. A palavra ‘saúde bucal’ foi associada à condição de limpeza da cavidade bucal, não identificando a saúde bucal como parte da saúde geral. O termo ‘transmissão da cárie’ não teve um entendimento suficiente. A expressão ‘dente permanente’ foi bem compreendida, sendo associada a um tipo de dente que não seria mais substituído. A palavra ‘flúor’ teve maior associação à função de limpeza do que à proteção dos dentes. Conclui-se que a utilização da técnica do Grupo Focal é de grande importância na interpretação do conhecimento dos adolescentes sobre saúde bucal e na adequação da terminologia de questionários sobre o mesmo tema.This study aims to the understanding of adolescents regarding oral health, using the Focus Group technique.

    This work involved the geological mapping (in the scale 1:60.000) of an area of 800 square kilometers in the nortwestern part of the state of Goias, near and east of the Araguaia river. Based on the stratigraphy, metamorphism, geochronology, magmatism and mineral deposits hypotheses on the geological evolution of the region are discussed. The area studied belongs to the Precambrian Araguaia Fold Belt. The oldest rocks identified are trondhjemitic gneisses and on these rocks was deposited a sedimentary sequence with minor volcanics of a geosynclinal type. The stratigraphic column of Abreu (1978) was adopted with minor modifications. The basement, of transamazonic age (2000 Ma), consists mostly of gneiss, migmatite, granite gneiss and amphibolite. The metasediments belongs to the lower unit (Estrondo Group) of the Supergroup Baixo Araguaia. The Estrondo Group, of brasilian age (600 Ma), consists in the area of the lowermost Morro do Campo Formation, mainly quartzite and amphibolite, which give the high relief of the brachyanticlines of Lontra and Ramal do Lontra.(author)

    Patients who visit online support groups benefit in various ways. Results of our earlier study indicated that participation in online support groups had a profound effect on the participants' feelings of "being empowered." However, most studies of online patient support groups have focused on the members of these groups who actively contribute by sending postings (posters). Thus far, little is known about the impact for "lurkers" (ie, those who do not actively participate by sending postings). In the present study, we explored if lurkers in online patient support groups profit to the same extent as posters do. We searched the Internet with the search engine Google to identify all Dutch online support groups for patients with breast cancer, fibromyalgia, and arthritis. Invitations to complete an online survey were sent out by the owners of 19 groups. In the online questionnaire, we asked questions about demographic and health characteristics, use of and satisfaction with the online support group, empowering processes, and empowering outcomes. The online questionnaire was completed by 528 individuals, of which 109 (21%) identified themselves as lurkers. Lurkers (mean age 47 years) were slightly older than active participants (mean age 43 years, P = .002), had a shorter disease history (time since diagnosis 3.7 years vs 5.4 years, P = .001), and reported lower mental well-being (SF 12 subscore 37.7 vs 40.5, P = .004). No significant differences were found in other demographic variables. Posters indicated visiting the online support groups significantly more often for social reasons, such as curiosity about how other members were doing, to enjoy themselves, as a part of their daily routine (all P posters did not differ in their information-related reasons for visiting the online support group. Lurkers were significantly less satisfied with the online support group compared to posters (P posters. However, lurkers did not differ significantly from posters with regard to

    Full Text Available Selecting a project team is a complex multi-criteria decision-making problem. For this reason, one appropriate way to tackle such problems involves the use of multi-criteria decision aid methods. However, most of the decisions taken regarding the selection of project teams are made by a group of people. It is this which changes the focus of the problem by moving from one decision-maker (DM to a group of DMs. Analysis needs to be extended in order to consider the preference structure of each individual group member. In this paper, we present a group decision model for project team selection based on a multi-criteria evaluation of the preferences of a client's representatives. It could be applied to any decision problem since it involves a group of decision makers whose preferences diverge little. An application of the model in order to select consultants for a construction project is presented.A seleção da equipe em um projeto é um problema de decisão multicritério. Uma forma apropriada de tratar tais problemas envolve o uso de métodos de apoio multicritério a decisão. Grande parte desses problemas envolve um grupo de decisores.

Pode ser aplicado a qualquer problema de decisão desde que envolva um grupo de decisores que tenham pequena divergência em relação às suas preferências.

    This paper focuses on the use of environmental information in investment decision making. The research approach employed was based on an experiment where three groups were asked to allocate investment funds between two companies based on financial accounts and information material from...... these companies. The overall conclusion of the paper is that even though environmental information is not enough in itself to shift decision preferences, it seems to have some impact on decision making. However, there seems to be a discrepancy between what decision makers say they do and what they actually do....... First, environmental information apparently has greater impact on decision making in the short run than the long run despite decision makers saying that they value environmental information more regarding long-run investments. Second, decision makers downplay the value of environmental information...

Assim, os componentes de uma mesma família possuem um comportamento semelhante quando expostos ao CO2 Supercrítico (CO2 SC. A seguir, utilizando a Equação de Peng-Robinson, realizou-se o cálculo do equilíbrio de fases no sistema óleo de manteiga/CO2, sendo o óleo de manteiga representado por uma mistura de 14 componentes hipotéticos, as famílias. Foram desenvolvidas correlações para a temperatura e pressão críticas e parâmetros de interação binária das famílias. O modelo foi capaz de correlacionar dados obtidos da literatura. As predições do equilíbrio de fases estão em excelente concordância com os dados obtidos pelos autores deste trabalho para os sistemas de óleo de manteiga/CO2. O procedimento mostrado aqui aplica-se não só ao dióxido de carbono supercrítico mas também a outros fluidos ou misturas de fluidos supercríticos, e também não somente ao óleo de manteiga, mas a todos os óleos/gorduras cuja constituição principal sejam triglicerídeos.Fractionation of butter oil into fractions with different physical and chemical properties is a possible solution for the problem of the excess of butter oil in the international market.

    The purpose of this study was to investigate whether variations in disfluencies of young children who do (CWS) and do not stutter (CWNS) significantly change their talker group classification or diagnosis from stutterer to nonstutterer, and vice versa. Participants consisted of 17 3- to 5-year-old CWS and 9 3- to 5-year-old CWNS, with no statistically significant between-group difference in chronological age (CWS: M = 45.53 months, SD = 8.32; CWNS: M = 47.67 months, SD = 6.69). All participants had speech, language, and hearing development within normal limits, with the exception of stuttering for CWS. Both talker groups participated in a series of speaking samples that varied by: (a) conversational partner [parent and clinician], (b) location [home and clinic], and (c) context [conversation and narrative]. The primary dependent measures for this study were the number of stuttering-like disfluencies (SLD) per total number of spoken words [%SLD] and the ratio of SLD to total disfluencies (TD) [SLD/TD]. Results indicated that significant variability of stuttering did not exist as a result of conversational partner or location. Changes in context, however, did impact the CWS, who demonstrated higher SLD/TD in the conversation sample versus a narrative sample. Consistent with hypotheses, CWS and CWNS were accurately identified as stutterers and nonstutterers, respectively, regardless of changes to conversational partner, location or context for the overall participant sample. Present findings were taken to suggest that during assessment, variations in stuttering frequency resulting from changes in conversational partner, location or context do not significantly influence the diagnosis of stuttering, especially for children not on the talker group classification borderline between CWS and CWNS.

    Full Text Available In this paper I speak from both a scientific and religious perspective. From this dual perspective I question the motivations that drive us to continue in the effort of doing scientific work. I ask the why and the wherefore of scientific work. To answer this question: What drives us to continue doing Science? I raise a preliminary question: What do we mean when we say ‘Science’? After briefly describing how the language of Modern Science has evolved in the last centuries, I distinguish between the knowledge that can be expressed by the formal languages of mathematics and the more personal and internal knowledge that can only be expressed by other languages that I call languages of symbol. Finally I propose positive and religious values that move us to continue doing science, while, together with more critical voices, also show the relativity of scientific work

    Full Text Available Background: Racial and ethnic diversity continues to grow in communities across the United States,raising questions about the extent to which different ethnic groups will become residentially integrated. Objective: While a number of studies have examined the residential patterns of pan-ethnic groups, our goal is to examine the segregation of several Asian and Hispanic ethnic groups - Cubans, Dominicans, Mexicans, Puerto Ricans, Salvadorans, Asian Indians, Chinese, Filipinos, Japanese, Koreans, and Vietnamese. We gauge the segregation of each group from several alternative reference groups using two measures over the 1980 to 2010 period. Results: We find that the dissimilarity of Hispanics and Asians from other groups generally held steady or declined, though, because most Hispanic and Asian groups are growing, interaction with Whites also often declined. Our analyses also indicate that pan-ethnic segregation indexes do not always capture the experience of specific groups. Among Hispanics, Mexicans are typically less residentially segregated (as measured using the dissimilarity index from Whites, Blacks, Asians, and other Hispanics than are other Hispanic-origin groups. Among Asian ethnic groups, Japanese and Filipinos tend to have lower levels of dissimilarity from Whites, Blacks, and Hispanics than other Asian groups. Examining different dimensions of segregation also indicates that dissimilarity scores alone often do not capture to what extent various ethnic groups are actually sharing neighborhoods with each other. Finally, color lines vary across groups in some important ways, even as the dominant trend has been toward reduced racial and ethnic residential segregation over time. Conclusions: The overarching trend is that ethnic groups are becoming more residentially integrated,suggestive of assimilation, though there is significant variation across ethnic groups.

  19. Pride, Shame and Group Identification

    Full Text Available Self-conscious emotions such as shame and pride are emotions that typically focus on the self of the person who feels them. In other words, the intentional object of these emotions is assumed to be the subject that experiences them. Many reasons speak in its favor and yet this account seems to leave a question open: how to cash out those cases in which one genuinely feels ashamed or proud of what someone else does?This paper contends that such cases do not necessarily challenge the idea that shame and pride are about the emoting subject. Rather, we claim that some of the most paradigmatic scenarios of shame and pride induced by others can be accommodated by taking seriously the consideration that, in such cases, the subject group-identifies with the other. This is the idea that, in feeling these forms of shame or pride, the subject is conceiving of herself as a member of the same group as the subject acting shamefully or in an admirable way. In other words, these peculiar emotive responses are elicited in the subject insofar as, and to the extent that, she is (or sees herself as being a member of a group – the group to which those who act shamefully or admirably also belong.By looking into the way in which the notion of group identification can allow for an account of hetero-induced shame and pride, this paper attempts to achieve a sort of mutual enlightenment that brings to light not only an important and generally neglected form of self-conscious emotions, but also relevant features of group identification. In particular, it generates evidence for the idea that group identification is a psychological process that the subject does not have to carry out intentionally in the sense that it is not necessarily triggered by the subject’s conative states like desires or intentions.

  20. A survey on blood group determination

    Detection of blood group is an essential factor in critical conditions before performing blood transfer. At presently tests are conducted by lab technicians manually in the laboratory. When the test is done by technicians with large samples it becomes monotonous to do and sometimes it leads to incorrect results and even its time consuming to get the result. The research survey proposal is to reduce the physical work to identify the blood group with a paper-based device. The paper is having a long thermometer with two ends. By using this we can detect the blood type by changing the color of the paper. Chemical reactions between dye, Bromo creosol green, and blood serum proteins, were performed to test the blood sample. The paper becomes teal or brown color, depending on whether the association of antibodies and antigens are present. It gives the result within 30 seconds, which is quicker than traditional detection system. The tested blood sample had a good accuracy rate.

Forty extracted premolars (80 root canals of dogs were used. The root canals were cleaned, shaped and filled by the lateral condensation technique using Sealer 26TM. The post space was created removing two thirds of the filling material within the root canal. The canals were randomly divided in three groups, which were treated as follows: Group A received the ScotchbondTM Multi-Purpose adhesive system; for Group B the cyanoacrylate adhesive, Super BonderTM, was employed; and no adhesive was applied into the post space for Group C (control group. A glass ionomer provisional restoration was placed allowing the sealer to set for 72 hours. Then the restoration was removed and the root canal was exposed to the oral environment for 45 days. The dogs were then killed and their jaws were removed. The post spaces were filled with India ink and the teeth were restored for 96 hours. Afterwards, the teeth were extracted and the roots were sectioned at the furcation for allocation to their specific groups. The teeth were turned transparent and the quantitative analysis of leakage was performed using light microscopy. The results showed no significant differences between groups, rejecting the initial hypothesis. Leakage occurred in a great extent in all specimens. Therefore, sealing post spaces with the adhesives used in this study was not an effective method to prevent microleakage.Esse estudo in vivo analisou a capacidade de selamento do canal protético com dois adesivos, o Super Bonder® (Henkel Loctite Adesivos Ltda., Itapevi, SP e o Scotchbond® Multi-Purpose (3M Dental Products, St. Paul, MN, EUA, testando a

We first did a cladistic analysis of the T. phyllostomae group and combined that analysis with a phylogenetic hypothesis from the literature for the Stenodermatinae bats. The cladistic analysis included, as outgroups, one species from each morphological group and complex of Trichobius Gervais, and one species from the following genera: Paratrichobius Miranda-Ribeiro, Megistopoda Macquart, Megistapophysys Dick & Wenzel, Neotrichobius Wenzel & Aitken, Speiseria Kessel and Strebla Wiedemann. The cladogram was rooted with a species of Strebla in the subfamily Streblinae. One cladogram was obtained and which found Trichobius to be polyphyletic. The phylogenetic hypothesis as follows: (Paratrichobius, (Neotrichobius, (Megistopoda, Megistapophysis is the sister-group of the phyllostomae group and the following relationships within the ingroup, (((T. vampyropis Wenzel, Trichobius sp. 2 ((T. hispidus Wenzel, T. petersoni Wenzel ((Trichobius sp. 1 (T. phyllostomae, T. brennani Wenzel. When we compared phylogenies through historical association analyses, cospeciation was uncommon, while host-switching was more common and better explained the association between the phyllostomae group and their bat hosts.

    Surgical techniques that draw from multiple types of image-based procedures (IBP) are increasing, such as Natural Orifice Transluminal Endoscopic Surgery, fusing laparoscopy and flexible endoscopy. However, little is known about the relation between psychomotor skills for performing different types of IBP. For example, do basic psychomotor colonoscopy and laparoscopy skills interact? Following a cross-over study design, 29 naïve endoscopists were trained on the Simbionix GI Mentor and the SimSurgery SEP simulators. Group C (n = 15) commenced with a laparoscopy session, followed by four colonoscopy sessions and a second laparoscopy session. Group L (n = 14) started with a colonoscopy session, followed by four laparoscopy sessions and a second colonoscopy session. No significant differences were found between the performances of group L and group C in their first training sessions on either technique. With additional colonoscopy training, group C outperformed group L in the second laparoscopy training session on the camera navigation task. Overall, training in the basic colonoscopy tasks does not affect performance of basic laparoscopy tasks (and vice versa). However, to limited extent, training of basic psychomotor skills for colonoscopy do appear to contribute to the performance of angled laparoscope navigation tasks. Thus, training and assessment of IBP type-specific skills should focus on each type of tasks independently. Future research should further investigate the influence of psychometric abilities on the performance of IBP and the transfer of skills for physicians who are experienced in one IBP type and would like to become proficient in another type of IBP.

    Cooperative learning may improve students' motivation, understanding of course concepts, and academic performance. This study therefore enhanced a cooperative, group-project learning technique with technology resources to determine whether doing so improved students' deep learning and performance. A sample of 118 engineering students, randomly divided into two groups, participated in this study and provided data through questionnaires issued before and after the experiment. The results, obtained through analyses of variance and structural equation modelling, reveal that technology-enhanced, cooperative, group-project learning improves students' comprehension and academic performance.

The objectives of the paper are to show the particularities of the variety spoken in the municipality and the convergence of varieties within the municipality. Based on a number of dialect markers (pronunciation of sogro, sogra, esterco, medo, novo, and birollo; the evolution of the Latin groups -ŭlt-, -ŭctand -ūct-; presence of viñen, bidueiro and filloas or variants of these elements, among others this paper shows that the varieties spoken in each area studied within the municipality have distinct features that differentiate them from the varieties spoken in other areas, and that four linguistic areas converge at the municipality of Castrelo do Val: the valley, the parish of San Xoán de Servoi, the parish of Santa Eufemia de Piornedo and the north (the former parsih of Santiago de Campobecerros and its annex, the parish of San Miguel de Portocamba. The secondary objective of this paper is to determine the innovative and conservative oral varieties of the municipality. Overall, some innovations are entering the valley, including din as compared to dei in the north. Innovations have also been observed in northern areas, such as viñen in Veiga de Nostre, and some conservative forms have been found in the valley, such as vin in Pepín, Ribas, Gondulfes and Castrelo do Val. Data was collected through two survey questionnaires that contained indirect questions. The survey was conducted among speakers from every area in the municipality with very little or no formal education. Survey data was corroborated or refined using additional data from recordings made in each area in the municipality.

    analyses how emotions of annoyance, hostility, shame and empathy circulate between the researcher, the gatekeepers and the studied people. Asking what do emotions do? the chapter looks into how the circulation of emotions establish both distance and proximity among the subjects. Spanger argues...... that such circulations of emotions springs from particular discourses of feminism and social policy. From this stance, emotions are approached as discursive practices that establish hierarchies among the implied subjects that forms the premises for producing knowledge.

    A differential curve of growth analysis of three K-giant stars (HD 2490, HD 130227 and HD 130694) assigned membership in Eggen's sigma Pup moving group is carried out relative to α Boo. This group is believed to represent a sample of very old disk population stars. The abundances of five elements in these stars do not differ greatly from α Boo, having [Fe/H] approximately equal to -0.5. This result agrees with those of Williams and Boyle and McClure using narrow and intermediate band photometry respectively. (author)

    Full Text Available INTRODUÇÃO: Estudos indicam que há uma associação entre tabagismo e transtorno do pânico, e alguns autores sugerem que o tabagismo aumenta o risco de ataques de pânico e transtorno do pânico. Este estudo analisa a hipótese de que pacientes fumantes com esse transtorno apresentam um quadro clínico mais grave. MÉTODO: Sessenta e quatro pacientes em tratamento no Laboratório do Pânico e Respiração (Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro, com transtorno do pânico, segundo critérios do Manual de Diagnóstico e Estatística das Perturbações Mentais (DSM, 4ª edição, foram divididos em grupos de tabagistas e não-tabagistas. Os grupos foram avaliados quanto a características sociodemográficas, comorbidades e gravidade do quadro clínico. RESULTADOS: Não houve diferença significativa em relação à gravidade do transtorno do pânico; no entanto, tabagistas tiveram prevalência de depressão significativamente maior (p = 0,014 do que não-tabagistas. CONCLUSÃO: Este estudo não evidenciou que o transtorno do pânico em tabagistas é mais grave, porém indicou que esses pacientes têm mais comorbidade com depressão.INTRODUCTION: Several studies indicate that panic disorder and tobacco smoking are associated, and some authors hypothesize that smoking increases the risk of panic attacks and panic disorder. The objective of this study is to investigate whether smokers have a more severe form of panic disorder than non-smokers. METHOD: Sixty-four patients already in treatment at the Laboratory of Panic and Respiration (Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro with panic disorder as established by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, were divided into groups of smokers and non-smokers.

  5. Factors affecting research productivity of production and operations management groups: An empirical study

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available This paper identifies factors that promote research productivity of production and operations management (POM groups of researchers in US business schools. In this study, research productivity of a POM group is defined as the number of articles published per POM professor in a specific period of time. The paper also examines factors that affect research quality, as measured by the number of articles published per POM professor in journals, which have been recognized in the POM literature as an elite set. The results show that three factors increase both the research productivity and the quality of the articles published by professors of a POM group. These factors are (a the presence of a POM research center, (b funding received from external sources for research purposes, and (c better library facilities. Doctoral students do assist in improving research quality and productivity, but they are not the driving force. These results have important implications for establishing policy guidelines for business schools. For example, real-world problems are funded by external sources and have a higher probability of publication. Furthermore, schools could place more emphasis on external funding, as most engineering schools do, since groups receiving external funding are more productive in terms of research.

    1996-03-01

    This safety design guide for grouping and separation describes the philosophy of physical and functional separation for systems, structures and components in CANDU 9 plants and provides the requirements for the implementation of the philosophy in the detailed plant design. The separation of the safety systems is to ensure that common cause events and functional interconnections between systems do not impair the capability to perform the required safety functions for accident conditions. The separation requirements are also applied to the design by grouping the plant systems into two basic groups. Group 1 includes the power production systems and Group 2 includes the safety related systems required for the mitigation of serious process failure. The Group 2 is further separated into subgroups to ensure that events that could cause failure of a special safety system in one subgroup can be mitigated by the other subgroup. The change status for the regulatory requirements, code and standards should be traced and this safety design guide shall be updated accordingly. 2 tabs., 6 figs. (Author) .new

    Immigrants play an increasingly important role in local labor markets. Not only do they grow steadily in number but also in cultural, educational, and skill diversity, underlining the necessity to distinguish between immigrant groups when studying discrimination against immigrants. We examined immigrant employees' subtle discrimination experiences in a representative sample in Switzerland, controlling for dispositional influences. Results showed that mainly members of highly competitive immigrant groups, from immediate neighbor countries, experienced workplace incivility and that these incivility experiences were related to higher likelihoods of perceived discrimination at work. This research confirms recent accounts that successful but disliked groups are particularly likely to experience subtle interpersonal discrimination.

    A third-party E-payment protocol based on quantum group blind signature is proposed in this paper. Our E-payment protocol could protect user's anonymity as the traditional E-payment systems do, and also have unconditional security which the classical E-payment systems can not provide. To achieve that, quantum key distribution, one-time pad and quantum group blind signature are adopted in our scheme. Furthermore, if there were a dispute, the manager Trent can identify who tells a lie.

  18. A study of the current group evaporation/combustion theories

    Science.gov (United States)

    Shen, Hayley H.

    1990-01-01

    Liquid fuel combustion can be greatly enhanced by disintegrating the liquid fuel into droplets, an effect achieved by various configurations. A number of experiments carried out in the seventies showed that combustion of droplet arrays and sprays do not form individual flames. Moreover, the rate of burning in spray combustion greatly deviates from that of the single combustion rate. Such observations naturally challenge its applicability to spray combustion. A number of mathematical models were developed to evaluate 'group combustion' and the related 'group evaporation' phenomena. This study investigates the similarity and difference of these models and their applicability to spray combustion. Future work that should be carried out in this area is indicated.

The varicose ulcer presents factors, besides the biological ones, which interfere in the cicatrization, in the relapse cases and in its effective resolution. The proposed activities aimed at producing behavior changes with the intention of achieving self-care, providing information, socializing the participants, and stimulating cooperation, searching for joint solutions, aggregating interdisciplinary spirit and improving the care. Two groups have been formed and a thematic schedule established. The results have showed higher adhesion to the treatment, behavioral changes, and adapted and more effective attitudes of the health team.

    This research is about people who have intellectual disabilities and live in a secure hospital. It is about a group of people who meet at a support group. The support group is for people who are lesbian, gay, bisexual or transgender. These people with intellectual disabilities helped with planning, doing, and telling other people about the research. They told their stories about going to the support group. Their stories were joined together into a group story. The story said that the group helped people in lots of different ways. For some people going to the group was difficult at first because it was ?coming out'. This means telling other people you are lesbian, gay, bisexual, or transgender. Then it got easier and people started to feel better about themselves. Then they wanted to help others and this was important in their lives. This group seemed to help people get better. We have given some ideas for setting up other groups and doing more research. © 2016 John Wiley & Sons Ltd.

    Full Text Available Este estudo investiga aspectos que levam à transformação do conto “Missa do galo” em palimpsesto. Quase oito décadas depois de sua publicação, a obra Missa do galo: variações sobre o mesmo tema é lançada, apresentando seis propostas de aproximação do texto original de Machado de Assis. Noções teóricas acerca da intertextualidade, bem como conceitos formulados pela Estética da Recepção embasam o desenvolvimento desta análise. A principal razão para entender por que a determinadas criações literárias é concedido o estatuto de hipotexto se deve ao fato de que a literatura desempenha uma função social, que se corporifica através do relacionamento prolífico do leitor com o texto. As obras são caracterizadas por indeterminações textuais. Machado intencionalmente as acentua, como se verifica em “Missa do galo”. Essa prática estimula a produção de textos que, de certo modo, procuram dar prosseguimento ao enredo delineado pelo autor carioca.

  11. Collective Action Problem in Heterogeneous Groups with Punishment and Foresight

    The collective action problem can easily undermine cooperation in groups. Recent work has shown that within-group heterogeneity can under some conditions promote voluntary provisioning of collective goods. Here we generalize this work for the case when individuals can not only contribute to the production of collective goods, but also punish free-riders. To do this, we extend the standard theory by allowing individuals to have limited foresight so they can anticipate actions of their group-mates. For humans, this is a realistic assumption because we possess a "theory of mind". We use agent-based simulations to study collective actions that aim to overcome challenges from nature or win competition with neighboring groups. We contrast the dynamics of collective action in egalitarian and hierarchical groups. We show that foresight allows groups to overcome both the first- and second-order free-rider problems. While foresight increases cooperation, it does not necessarily result in higher payoffs. We show that while between-group conflicts promotes within-group cooperation, the effects of cultural group selection on cooperation are relatively small. Our models predict the emergence of a division of labor in which more powerful individuals specialize in punishment while less powerful individuals mostly contribute to the production of collective goods.

  14. Cultural Values in Intergroup and Single-Group Social Dilemmas.

    1999-03-01

    Do cultural values influence the manner in which people cooperate with one another? This study assessed cultural characteristics of individuals and then related these characteristics to cooperative behavior in social dilemmas. Participants were assessed for their degree of vertical and horizontal individualism and collectivism, cultural values identified by Triandis (1995). They made choices in either a single-group or an intergroup social dilemma. The single-group dilemma entailed a three-person dilemma; the intergroup dilemma was identical but added subgroup competition, i.e., an opposing three-person group. The results indicated an interaction between cultural characteristics and type of dilemma for cooperation. The single-group versus intergroup effect reported by Bornstein and Ben-Yossef (1994) was replicated, but only for vertical individualists. The vertical individualists were least cooperative in the single-group dilemma but were more cooperative in the intergroup dilemma-where cooperation with the group maximized personal outcomes. The vertical collectivists were most cooperative in the single-group dilemma but were less cooperative in the intergroup dilemma- where group defection resulted in maximum group outcomes. The horizontal individualists and collectivists exhibited an intermediate level of cooperation, with no differences in cooperation between the single-group and intergroup dilemmas. Taken together, the results suggest that the relationship between cultural values and cooperation, in particular with reference to vertical and horizontal components of individualism and collectivism, is more complex than has been suggested in past research.

  15. Preschoolers' group bias in punishing selfishness in the Ultimatum Game.

    Wu, Zhen; Gao, Xiaohe

    2018-02-01

    Previous studies have shown that both adults and children tend to favor members of their own group and expect reciprocity of such in-group privilege. If a person is treated unfairly by an in-group member, a conflict arises between the tendency of in-group favoritism and the desire to punish violators of in-group norms. How do children solve the conflict at different points in development? We compared how preschoolers punished in-group and out-group members (marked by color preference) for selfishness in the Ultimatum Game. We found that (a) 3- to 6-year-old Chinese children rejected selfish allocations more often than fair ones, showing a robust preference for fairness; (b) 3- and 4-year-olds showed no group differences in their punishment behavior, suggesting that second-party punishment of selfishness is not biased during early childhood; (c) 5- and 6-year-old girls were more likely to punish selfishness of in-groups than of out-groups, illuminating an early sign of maintaining group-based fairness norms even at a personal cost; and (d) 5- and 6-year-old boys, however, punished in-groups and out-groups equally often and punished out-groups more often than did girls. These age and gender differences in children's punishment imply that socialization may play an important role in showing group bias when enforcing fairness norms. Copyright © 2017 Elsevier Inc.

    Full Text Available Discute-se o conceito de cultura em relação à microcultura do grupo de brinquedo. Concebe-se a criança como agente de criação e transmissão de cultura e o grupo de brinquedo como espaço de informação onde esses processos ocorrem. Essa concepção baseia-se no reconhecimento da espécie humana como biologicamente sócio-cultural e na pressuposição de adaptações precoces para essa especificidade.

Objetivou-se com este trabalho avaliar a técnica do micro-hematócrito em relação ao peso corporal e características reprodutivas (fertilidade, eclodibilidade e nascimento visando sua utilização pelos programas de melhoramento genético. Dois grupos contrastantes foram constituídos, baseados na seleção fenotípica de 630 reprodutores de 18 genótipos para a característica hematócrito. Progênies das aves selecionadas, 74 pintos não sexados (40 do grupo de hematócrito alto e 34 do grupo baixo foram criados com manejo convencional. Os pesos corporais e os valores de hematócrito foram mensurados aos 14 e 42 dias de idade. Para avaliar as características reprodutivas, ovos de 42 matrizes (22 do grupo alto e 20 do baixo foram incubados. As médias foram estimadas utilizando-se um modelo linear com o efeito fixo do grupo genético. Os pintos do grupo baixo apresentaram as maiores médias de peso corporal (305,59 e 1387,06 g, diferindo dos pintos do grupo alto os quais apresentaram médias de peso de 243,56 e 1128,11 g aos 14 e 42 dias de idade, respectivamente. Também para o valor do hematócrito os grupos diferiram significativamente.

Patients were distributed in four groups according to distal latencies severity. There was an increase in age as long as SDL/MDL became more severe, ranging from 47.5 to 67 years old (mild to severe-absence potentials in both hands groups, respectively. There was a less dramatic increase in duration of complaints as long as SDL/MDL became more severe, ranging from 12 to 30.7 months (mild to severe-absence potentials in both hands groups, respectively. Aging correlates more positively than duration of complaints with severity of SDL/MDL in CTS. The effects of increasing median blockage in CTS are more severe as long as patients become older regardless duration of symptomatology.Latências distais sensitivas e motoras (LDS/LDM do nervo mediano foram correlacionadas com idade e duração da sintomatologia em 1498 pacientes com síndrome do túnel do carpo (STC; a idade variou de 17 a 90 anos e 87,6% eram do sexo feminino. Os casos foram distribuídos em quatro grupos de acordo com a gravidade das latências distais. Houve aumento de idade proporcional ao aumento de LDS/LDM, variando de 47,5 a 67 anos nos grupos leve e grave-ausência de potenciais nas duas mãos, respectivamente. Houve aumento menos dramático na duração da sintomatologia proporcional ao aumento de LDS/LDM, variando de 12 a 30,7 meses nos grupos leve e grave-ausência de potenciais nas duas mãos, respectivamente. O aumento da idade correlaciona-se melhor que a duração da sintomatologia com o aumento de LDS/LDM. Os efeitos do aumento do bloqueio do nervo mediano no STC são mais graves com o avanço da idade, independentemente da duração da sintomatologia.

    We examined whether a program combining cognitive-behavioural therapy (CBT), vestibular rehabilitation (VR) and psychoeducation is equally effective in improving psychometric measures in patients with dizziness independent of a balance deficit. Measures of patients with dizziness only (DO) were compared to those of patients also having a quantified balance deficit (QBD). 32 patients (23 female, 9 male) with persistent dizziness were analysed as 2 groups based on stance and gait balance control: those with QBD (pathological balance) or DO (normal balance). Dizziness Handicap Inventory (DHI) and Brief Symptom Inventory (BSI) questionnaires were used pre- and post-therapy to assess psychometric measures. Patients then received the same combination therapy in a group setting. The QBD group mean age was 60.6, SD 8.3, and DO group mean age 44.8, SD 12.1, years. Pre-therapy, questionnaire scores were pathological but not different between groups. Balance improved significantly for the QBD group (p=0.003) but not for the DO group. DHI and BSI scores improved significantly in the DO group (0.001balance control improving to near normal. Possibly, greater focus on phobic anxiety during the group therapy program would have improved psychological measures of QBD patient. Copyright © 2017 Elsevier Inc. All rights reserved.

However, there are few studies that have examined the effects of cognitive behavioral group therapy on the course of this disorder. The aim of the present study was to evaluate the effectiveness of 14 sessions of cognitive behavioral group therapy, combined with pharmacotherapy, on the treatment of patients with bipolar disorder, and to compare our results against those from the use of pharmacotherapy alone. METHOD: Forty-one patients with bipolar I and II disorder participated in the study and were randomly allocated to one of two treatment groups; thirty-seven patients remained in the study until its completion. Mood and anxiety symptoms were measured in all subjects. Statistical analysis was used to investigate if the groups differed with respect to demographic characteristics and the scores recorded in the pre- and post-treatment stages, as well as during treatment (intra/inter groups. RESULTS: Patients showed statistically similar population characteristics. The association of cognitive behavioral group therapy and pharmacological treatment proved to be effective.

    2017-10-01

    This study examines how group members' questions shape member participation in health counselling and health education groups. The study applies conversation analytic principles as a method. The data consist of video-recorded health education lessons in secondary school and health counselling sessions for adults with a high risk of Type 2 diabetes. Group members' questions accomplish a temporary change in participatory roles. They are used to 1) request counselling, 2) do counselling or 3) challenge previous talk. They are usually treated as relevant and legitimate actions by the participants, but are occasionally interpreted as transitions outside the current action or topic. Group members' questions result in a shift from leader-driven to member-driven discussion. Thus they constitute a pivot point for detecting changes in participation in group interventions. Observing the occurrence of group members' questions helps group leaders to adjust their own actions accordingly and thus facilitate or guide group participation. Comparison of the type and frequency of members' questions is a way to detect different trajectories for delivering group interventions and can thus be used to develop methods for process evaluation of interventions.

    Social reasoning and norms among individuals that share cultural traits are largely fashioned by those traits. We have explored predominant sociological and cultural traits. We offer a methodology for parametrically adjusting relevant traits. This exploratory study heralds a capability to deliberately tune cultural group traits in order to produce a desired group behavior. To validate our methodology, we implemented a prototypical-agent-based simulated test bed for demonstrating an exemplar from intelligence, surveillance, and reconnaissance scenario. A group of simulated agents traverses a hostile territory while a user adjusts their cultural group trait settings. Group and individual utilities are dynamically observed against parametric values for the selected traits. Uncertainty avoidance index and individualism are the cultural traits we examined in depth. Upon the user's training of the correspondence between cultural values and system utilities, users deliberately produce the desired system utilities by issuing changes to trait. Specific cultural traits are without meaning outside of their context. Efficacy and timely application of traits in a given context do yield desirable results. This paper heralds a path for the control of large systems via parametric cultural adjustments.

  14. Modified two-fluid model for the two-group interfacial area transport equation

    2003-01-01

    This paper presents a modified two-fluid model that is ready to be applied in the approach of the two-group interfacial area transport equation. The two-group interfacial area transport equation was developed to provide a mechanistic constitutive relation for the interfacial area concentration in the two-fluid model. In the two-group transport equation, bubbles are categorized into two groups: spherical/distorted bubbles as Group 1 while cap/slug/churn-turbulent bubbles as Group 2. Therefore, this transport equation can be employed in the flow regimes spanning from bubbly, cap bubbly, slug to churn-turbulent flows. However, the introduction of the two groups of bubbles requires two gas velocity fields. Yet it is not practical to solve two momentum equations for the gas phase alone. In the current modified two-fluid model, a simplified approach is proposed. The momentum equation for the averaged velocity of both Group-1 and Group-2 bubbles is retained. By doing so, the velocity difference between Group-1 and Group-2 bubbles needs to be determined. This may be made either based on simplified momentum equations for both Group-1 and Group-2 bubbles or by a modified drift-flux model

    Full Text Available Resumo O artigo investiga a composição das fileiras de soldados e oficiais da Guarda Nacional na província do Rio Grande do Sul, durante os anos de centralização política da administração da milícia (1850-1873. Dessa forma, busca solapar a imagem já clássica do sul do Brasil, onde, supostamente, os homens em armas seriam sobretudo peões sob as ordens de estancieiros, facilmente mobilizáveis para as lides guerreiras - configuração, aliás, que pretensamente seria a marca indelével da estrutura social da região. A partir das listas de qualificação da Guarda Nacional, o trabalho revela uma fotografia muito mais complexa da sociedade brasileira na parte meridional do país, dando especial enfoque aos homens livres, libertos e pobres que faziam parte da milícia. Sendo a Guarda a espinha dorsal do híbrido sistema militar do Império, conclui-se que foi através dessas redes e cadeias de interdependência que os assuntos de guerra eram gerenciados ali, conformando a própria natureza do Estado Imperial.

  17. A new compact for owners and directors. The Working Group on Corporate Governance.

    Science.gov (United States)

    1991-01-01

    The virtual demise of hostile takeovers and leveraged buyouts has not cooled the tensions over corporate governance. In congressional hearings, at annual meetings, and in proxy contests splashed across the business pages, senior executives and powerful shareholders continue to confront each other. The basic issues remain remarkably consistent. When do investors' legitimate needs for returns translate into destructive pressures on long-term corporate prosperity? What kinds of accountability do top managers owe shareholders in terms of strategic consultation and disclosure? What is the precise role of the board of directors as a management monitor and shareholder representative? More than a year ago, a working group of distinguished lawyers representing large public companies and leading institutional investors began a series of meetings to cut through the rancor. Their goal was to reach common ground on a set of principles that reconciles the tensions between owners and managers. Recently, the group agreed on a statement that all eight members endorsed. The statement, "A New Charter for Owners and Managers," deserves wide readership, scrutiny, and commentary. HBR is pleased the working group chose it as the exclusive forum to release its statement.

    The objective of this study was to gain an understanding of whether pharmacy students are using Facebook ® to create formal or informal workplace-based peer groups to learn from each other and share information while completing their advanced pharmacy practice experiences (APPEs). Fourth-year pharmacy students from two colleges of pharmacy in the same geographical area were recruited by email to participate. Inclusion criteria were: completion of two or more APPEs, current assignment to an APPE rotation in the local area, and a Facebook ® profile. Two focus groups, of eight students each were conducted on each of the two colleges' campuses. An incentive to participate was provided. Thematic analysis was used to analyze responses. Students reported using Facebook ® to learn about rotation expectations, roles/responsibilities, and preceptors. However, frequency and depth of interactions varied among the participants. Most participants noted that they prefer more private methods of communication to learn about APPE experiences. Students found Facebook ® to be a good source of motivation and support during experiential learning. The use of social media sites like Facebook ® may help students form "virtual" workplace-based peer groups during APPEs. Pharmacy schools interested in providing support for formal workplace-based learning groups should consider using social media sites as one component of this program. Copyright © 2017 Elsevier Inc.

This study was performed by the group tutors with the objective to report on the development of the virtual learning environment (VLE) and the tutors' experience as mediators of a research group using the Moodle platform. To do this, a VLE was developed and pedagogical mediation was performed following the theme of mentoring. An initial diagnosis was made of the difficulties in using this technology in interaction and communication, which permitted the proposal of continuing to use the platform as a resource to support research activities, offer lead researchers the mechanisms to socialize projects and offer the possibility of giving advice at a distance.

    Bi-partite networks are commonly modelled using latent class or latent feature models. Whereas the existing latent class models admit marginalization of parameters specifying the strength of interaction between groups, existing latent feature models do not admit analytical marginalization...... by the notion of community structure such that the edge density within groups is higher than between groups. Our model further assumes that entities can have different propensities of generating links in one of the modes. The proposed framework is contrasted on both synthetic and real bi-partite networks...... feature representations in bipartite networks provides a new framework for accounting for structure in bi-partite networks using binary latent feature representations providing interpretable representations that well characterize structure as quantified by link prediction....

Foi realizado um estudo caso-controle de base hospitalar. Os casos foram 600 trabalhadores entre 15 e 60 anos que sofreram acidentes ocupacionais típicos entre maio e outubro de 2004, atendidos na Central de Ortopedia e Traumatologia de Piracicaba. Os controles foram 822 trabalhadores entre 15 e 60 anos que sofreram acidente não ocupacional e receberam o primeiro atendimento no serviço ou foram trabalhadores acompanhantes dos acidentados. Foi ajustado um modelo de regressão logística múltipla, tendo como variável independente o acidente do trabalho, controlada por co-variáveis de interesse, entre elas a exposição ao ruído. Estimou-se que o risco de sofrer acidente do trabalho é cerca de duas vezes maior entre trabalhadores expostos ao ruído, controlado para diversas co-variáveis. A exposição ocupacional ao ruído não só deteriora a saúde auditiva do trabalhador, mas também se constitui em fator de risco para acidentes do trabalho.The purpose of this study was to verify whether occupational noise exposure is a significant risk factor for work accidents in the city of Piracicaba, São Paulo State, Brazil.

    Full Text Available The United States has a long history of religious influence on public policy: the anti-slavery movement, progressivism, prohibition, civil rights, abortion, school vouchers, school prayer and nuclear disarmament are all issues that have involved religion and religious groups in policymaking. In recent decades, the number of religious interest groups (as well as interest groups in general has greatly expanded, but the role that the religious organizations play as interest groups in the policy arena has received relatively little attention. How are they similar to and different from other interest groups? What tactics do they use? How successful are they? Under what conditions is success or failure more likely? This article examines Roman Catholic religious groups as interest groups in the congressional policymaking process. First, it places Catholic interest groups in the context of the interest group literature, and second, it examines Catholic interest groups’ activity in the passage of welfare reform in 1996 and in the passage of health care reform in 2010. In both cases, they played a greater role in context-setting than in actually changing provisions.

The system was able to treat up to 3926L OWWday -1 , and consisted of an activated-carbon pretreatment column and a tubular PBR unit (80 tubes, 98.17L volume, 2-m height, 0.25m diameter). PBR was an effective and environmentally friendly method for the removal of phenols, COD, BOD 5 , turbidity and color from OWW (average efficiencies 94.84±0.55%, 85.86±1.24%, 99.12±0.17%, 95.86±0.98% and 87.24±0.91%, respectively). The diversity of total bacteria and microalgae in the PBR was analyzed using Illumina-sequencing, evaluating the efficiency of two DNA extraction methods. A stable microalgae-bacteria consortium was developed throughout the whole experimentation period, regardless of changes in HRT, temperature or solar radiation. MDS analyses revealed that the interplay between green algae (Sphaeropleales), cyanobacteria (Hapalosiphon) and Proteobacteria (Rhodopseudomonas, Azotobacter) played important roles in OWW bioremediation.

    Full Text Available Abstract Background Persistent presentation of medically unexplained symptoms (MUS is troublesome for general practitioners (GPs and causes pressure on the doctor-patient relationship. As a consequence, GPs face the problem of establishing an ongoing, preferably effective relationship with these patients. This study aims at exploring GPs' perceptions about explaining MUS to patients and about how relationships with these patients evolve over time in daily practice. Methods A qualitative approach, interviewing a purposive sample of twenty-two Dutch GPs within five focus groups. Data were analyzed according to the principles of constant comparative analysis. Results GPs recognise the importance of an adequate explanation of the diagnosis of MUS but often feel incapable of being able to explain it clearly to their patients. GPs therefore indicate that they try to reassure patients in non-specific ways, for example by telling patients that there is no disease, by using metaphors and by normalizing the symptoms. When patients keep returning with MUS, GPs report the importance of maintaining the doctor-patient relationship. GPs describe three different models to do this; mutual alliance characterized by ritual care (e.g. regular physical examination, regular doctor visits with approval of the patient and the doctor, ambivalent alliance characterized by ritual care without approval of the doctor and non-alliance characterized by cutting off all reasons for encounter in which symptoms are not of somatic origin. Conclusion GPs feel difficulties in explaining the symptoms. GPs report that, when patients keep presenting with MUS, they focus on maintaining the doctor-patient relationship by using ritual care. In this care they meticulously balance between maintaining a good doctor-patient relationship and the prevention of unintended consequences of unnecessary interventions.

Paratanto, procuramos traçar a maneira pela qual este tema surge no século XIX, acompanhando as discussões colocadas pela historiografia da época. Além disto, examinamos a construção de uma iconografia referente ao assunto, por intermédio das obras de Victor Meirelles e Oscar Pereira da Silva, entre outros. A circulação do tema e de sua representação iconográfica é abordada ainda pela análise dos panoramas do começo do século XX, das imagens nos livros didáticos deste período e do cinema dos primeiros tempos no Brasil. Por fim, procuramos entender como a obra do diretor mineiro dialoga com esta produção, apontando para as especificidades do próprio filme enquanto meio de comunicação.This article discusses the production and circulation forms of the Brazilian discovery theme, through the analysis of the film "Descobrimento do Brasil" (1937 from Humberto Mauro. For that, we explore the way this theme appears in the XIX century, following the historiographic discussions of this epoch. Besides, we examine the construction of an iconography related to this subject, through the production of Victor Meirelles and Oscar Pereira da Silva, among others. The circulation of this theme and its iconographic representation is also debated via the analysis of the panoramas from the beginning of XX century, via the images in the didactic books of this time and via the first productions of the Brazilian cinema. Finally, we try to understand how "Descobrimento do Brasil" dialogues with this production, highlighting the specificity of the film itself as a means of communication.

    The current article examines if, and under which conditions, there exists a positive relationship between working with friends and group performance. To do so, using data from 1,016 groups obtained from 26 studies, we meta-analyzed comparisons of the performance of friendship groups versus acquaintance groups. Results show that friendship has a significant positive effect on group task performance (Cohen's d = 0.31). Furthermore, this relationship was moderated by group size (i.e., the positive effect of friendship on performance increased with group size) and task focus (i.e., friendship groups performed better than acquaintance groups on tasks requiring a high quantity of output, whereas there was no performance benefit on tasks requiring a single or high-quality output). These results help to reconcile mixed findings and illustrate when friendship groups are more likely to perform better than acquaintance groups.

    Full Text Available O trabalho avalia o uso de técnicas agroecológicas pela produção familiar na região centro-sul do Estado do Paraná. Utiliza-se a metodologia de diagnóstico rápido dos sistemas agrários, tendo como referência trabalho desenvolvido na região pela AS-PTA, ONG que visa o desenvolvimento de agricultores familiares a partir do fomento de tecnologias agroecológicas. Após caracterização dos sistemas de produção dos agricultores pesquisados e do ambiente social que os cerca, finaliza-se com uma avaliação dos indicadores econômicos. Verifica-se uma relação entre o grau de capitalização dos agricultores e a adoção de práticas agroecológicas, a qual aumenta à medida que se reduz o grau de capitalização, sendo menor o risco econômico da atividade agrícola dos agricultores com maior índice de adoção. Conclui-se que há um potencial positivo da utilização da agroecologia como instrumento para o desenvolvimento sustentável de agricultores familiares, realçando-se a importância do apoio do poder público na dinamização deste processo.The paper analyzes the adoption of agro-ecological techniques by a group of small family farmers in a region of the State of Paraná. The sample of the farmers to be interviewed was obtained by applying a methodology of fast rural assessment and relied on the work of a non governmental organization (AS-PTA that has the major responsible for the technological change in the region. A typology of producers and agrarian systems was obtained, which made it possible to evaluate the technological trajectories followed. A negative correlation was observed between the capitalization level of the farm unity and the adoption of agro-ecological techniques, suggesting that the latter are being introduced as a low risk strategy to improve the production conditions within a context of labor abundance and capital scarcity. The paper concludes that it is worth to support those farmers in their decision

    We use 413 weeks of publicly available Fermi Pass 8 gamma-ray data combined with recently developed galaxy group catalogs to search for evidence of dark matter annihilation in extragalactic halos. In our study, we use luminosity-based mass estimates and mass-to-concentration relations to infer the J factors and associated uncertainties for hundreds of galaxy groups within a redshift range z≲0.03. We employ a conservative substructure boost factor model, which only enhances the sensitivity by an O(1) factor. No significant evidence for dark matter annihilation is found, and we exclude thermal relic cross sections for dark matter masses below ∼30  GeV to 95% confidence in the bb[over ¯] annihilation channel. These bounds are comparable to those from Milky Way dwarf spheroidal satellite galaxies. The results of our analysis increase the tension but do not rule out the dark matter interpretation of the Galactic Center excess. We provide a catalog of the galaxy groups used in this study and their inferred properties, which can be broadly applied to searches for extragalactic dark matter.

    Determination of the carbon and oxygen isotopic compositions were made on approximately 100 samples of Late Precambrian metasedimentary rocks of the Rio Pardo Group from Southern Bahia. The results obtained show that carbon varies from δ 13 =C=5,73 per mille to δ 13 C=+9,00 per mille, and oxygen from δ 18 O=-1,87 per mille to δ 18 O=-19,67 per mille relative to PBD. The interpretations lead to some conclusions which confirm the validity the isotopic technique as auxiliary instrument in the study of geological problems. These include: 1) the evidence of a marine transgression during the Camaca sedimentation; 2) the probability that the dolomitic metalimestones of the Agua Preta formation belong to the Serra do Paraiso formation; 3) the assignment of the dolomitic metalismestones, which occur in Itiroro and which had been previously grouped with the crystalline basement rocks, to the Serra do Paraiso formation; 4) the removal of the marble from Serra do Paraiso formation and re-signment to the basement rocks, and finally; 5) the sedimentary evolution of the Rio Pardo Group from a typical fresh-water to a marine environment.

    Full Text Available RESUMO Em contraste com vários outros estados brasileiros, apenas recentemente o Mato Grosso do Sul iniciou o inventário organizado de sua avifauna. Relacionamos 630 espécies de aves para o Mato Grosso do Sul, pertencentes a 26 ordens e 74 famílias, que corresponde a 34% da avifauna ocorrente no Brasil. Cerca de 90% dessas espécies apresentam registros comprobatórios de ocorrência no estado conforme as normas propostas pelo CBRO. As demais ainda aguardam documentação comprobatória adequada. Quarenta e cinco espécies foram incluídas na lista terciária por apresentarem problemas de documentação comprobatória devido à ausência de circunstanciação e distribuição incompatível. A grande diversidade de fitofisionomias e paisagens sob influência dos biomas Cerrado, Pantanal, Chaco, Bosques Chiquitanos e Mata Atlântica são responsáveis em parte, pela diversidade de espécies ocorrentes no Mato Grosso do Sul. No entanto, várias dessas fitofisionomias e paisagens já foram suprimidas e/ou alteradas pela pecuária e principalmente monoculturas ( Pinus, Eucalyptus e cana-de-açúcar. Trinta e sete espécies de aves ocorrentes no estado encontram-se presentes em listas de espécies ameaçadas de extinção em âmbito global e/ou nacional. Ainda existem grandes lacunas de conhecimento sobre a avifauna sul-matogrossense, notadamente no Pantanal do Paiaguás e em regiões limítrofes com o estado de Goiás e países como Paraguai (Chaco e a Bolívia (Bosques Chiquitanos.

    2001-09-01

    Full Text Available INTRODUÇÃO/OBJETIVOS: Há poucos trabalhos publicados sobre psicoterapia grupal para pacientes com transtorno de pânico (TP; além disso, esses estudos geralmente são restritos a abordagens cognitivo-comportamentais. O objetivo deste trabalho é relatar uma experiência de atendimento psicoterápico psicodramático grupal para portadores de TP, iniciada em 1996 na Faculdade de Medicina de Botucatu/Unesp, e discutir aspectos psicodinâmicos desse transtorno. MÉTODOS: Atende-se uma média de oito a dez pacientes em sessões mensais de duas horas de duração, nas quais se utilizam técnicas psicodramáticas. O uso associado de psicofármacos é a regra. A temática é aberta, centrando-se tanto em aspectos próprios do TP (sintomas mais comuns; peregrinação em serviços médicos até o diagnóstico; preocupações hipocondríacas; limitações e dependência; reações dos familiares; estratégias de exposição e enfrentamento; efeitos e reações dos medicamentos quanto em problemas individuais específicos. RESULTADOS: A abordagem psicodramática favorece a identificação e a elaboração de aspectos psicodinâmicos. Entre estes, destacaram-se os sentimentos de desamparo e seus desdobramentos: insegurança; fragilidade e medo; raiva e culpa; sentimentos de desamor e rejeição; vergonha e inferioridade; isolamento e dificuldade de pedir ajuda; dificuldade de identificar e de expressar sentimentos - manifestados somaticamente -; e dificuldade de assumir o papel de "cuidador" e outras responsabilidades. CONCLUSÕES: Aspectos valiosos para o tratamento do TP, como apoio mútuo, companheirismo, confiança, modelo e estímulo, são favorecidos pelo contexto grupal homogêneo. O compartilhar de experiências e sofrimentos comuns propiciou rápida coesão e suporte grupal, melhora da capacidade de expressar sentimentos e da auto-estima e o aprimoramento de papéis sociais. Além da melhora dos sintomas, possibilitou-se a melhor compreensão e

    2012-08-01

    In this paper, we go beyond recognizing the actions of individuals and focus on group activities. This is motivated from the observation that human actions are rarely performed in isolation; the contextual information of what other people in the scene are doing provides a useful cue for understanding high-level activities. We propose a novel framework for recognizing group activities which jointly captures the group activity, the individual person actions, and the interactions among them. Two types of contextual information, group-person interaction and person-person interaction, are explored in a latent variable framework. In particular, we propose three different approaches to model the person-person interaction. One approach is to explore the structures of person-person interaction. Differently from most of the previous latent structured models, which assume a predefined structure for the hidden layer, e.g., a tree structure, we treat the structure of the hidden layer as a latent variable and implicitly infer it during learning and inference. The second approach explores person-person interaction in the feature level. We introduce a new feature representation called the action context (AC) descriptor. The AC descriptor encodes information about not only the action of an individual person in the video, but also the behavior of other people nearby. The third approach combines the above two. Our experimental results demonstrate the benefit of using contextual information for disambiguating group activities.

    Full Text Available A definição construcionista do grupo terapêutico como uma prática discursiva enfatiza o caráter de negociação do processo de preparação e composição do grupo. Considerando esta perspectiva, o objetivo deste trabalho é compreender como determinadas formas de conversar contribuem para o processo de preparação e composição de um grupo de apoio para portadores do HIV. O grupo estudado consistiu de 10 sessões com 4 participantes. As sessões foram gravadas e transcritas. Através da análise discursiva dos momentos grupais, foi possível descrever a preparação para o grupo através de três processos conversacionais de: co-responsabilização do participante e construção inicial do pedido; co-responsabilização do terapeuta e renegociação do contrato; e 'aproximação discursiva' das descrições dos participantes. Em relação à composição do grupo, a inclusão no grupo não foi ditada a priori a partir de características do indivíduo, mas implicou um exercício de 'engajamento relacional' entre terapeuta e participantes.The constructionist definition of group therapy as a discursive practice emphasizes the character of negotiation in the process of group preparation and composition.

    Collective decision-making regarding direction of travel is observed during natural motion of animal and cellular groups. This phenomenon is exemplified, in the simplest case, by a group that contains two informed subgroups that hold conflicting preferred directions of motion. Under such circumstances, simulations, subsequently supported by experimental data with birds and primates, have demonstrated that the resulting motion is either towards a compromise direction or towards one of the preferred targets (even when the two subgroups are equal in size). However, the nature of this transition is not well understood. We present a theoretical study that combines simulations and a spin model for mobile animal groups, the latter providing an equilibrium representation, and exact solution in the thermodynamic limit. This allows us to identify the nature of this transition at a critical angular difference between the two preferred directions: in both flocking and spin models the transition coincides with the change in the group dynamics from Brownian to persistent collective motion. The groups undergo this transition as the number of uninformed individuals (those in the group that do not exhibit a directional preference) increases, which acts as an inverse of the temperature (noise) of the spin model. When the two informed subgroups are not equal in size, there is a tendency for the group to reach the target preferred by the larger subgroup. We find that the spin model captures effectively the essence of the collective decision-making transition and allows us to reveal a noise-dependent trade-off between the decision-making speed and the ability to achieve majority (democratic) consensus.

    Full Text Available Thanks to its use independently of time and place during the process of software development and by making it easier to access to information with mobile technologies, cloud based environments attracted the attention of education world and this technology started to be used in various activities. In this study, for programming education, the effects of extracurricular group assignments in cloud based environments on learners were evaluated in terms of group work satisfaction, ease of use and user satisfaction. Within the scope of computer programming education lasting eight weeks, a total of 100 students participated in the study including 34 men and 66 women. Participants were divided into groups of at least three people considering the advantages of cooperative learning in programming education. In this study carried out in both conventional and cloud based environments, between groups factorial design was used as research design. The data collected by questionnaires of opinions of group work were examined with quantitative analysis method. According to the study results extracurricular learning activities as group activity created satisfaction. However, perceptions of easy use of the environment and user satisfaction were partly positive. Despite the similar understandings; male participants were easier to perceive use of cloud computing based environments. Some variables such as class level, satisfaction, computer and internet usage time do not have any effect on satisfaction and perceptions of ease of use. Evening class students stated that they found it easy to use cloud based learning environments and became more satisfied with using these environments besides being happier with group work than daytime students.

    Full Text Available In the last three decades, exotic tree species are being introduced in the natural pastures of the highlands located at the northeastern part of Rio Grande do Sul State (RS, Brazil. This alteration of land use may impart drastic changes in the soil attributes. In this context, this work aimed to evaluate the impact of Pinus taeda afforestation on soil chemical attributes and organic matter (SOM composition in Leptosols from Campos de Cima da Serra, RS. Soil samples under eight year old (Pi8 and 30 year old (Pi30 Pinus plantations and under native pasture (NP were studied. Contents of exchangeable cations and of micronutrients and soil pH were determined. The SOM composition was investigated by means of elemental analyses and FTIR spectroscopy. The soil under pasture had a higher content of nutrients and of SOM in comparison to Pinus soils, reflecting the higher input and decomposition rate of the below ground added residue in the grassland environment. The SOM in pasture soils showed a higher content of carbohydrate and of structures derived from microbial metabolism. Besides the depletion of nutrients and of SOM, Pinus afforestation affected the SOM quality: following afforestation, the proportion of chemically recalcitrant structures and of carboxylic groups increased, whereas N-containing groups decreased.Nas três últimas décadas, o cultivo de espécies exóticas vem sendo introduzido nas áreas de pastagem de solos de altitude localizados na região nordeste do Estado do rio Grande do Sul.

    ABSTRACTThis article provides a review of immunity, diagnosis, and clinical aspects of rotavirus disease. It also informs about the changes in epidemiology of diarrheal disease and genetic diversity of circulating group A rotavirus strains following the introduction of vaccines. Group A rotavirus is the major pathogen causing gastroenteritis in animals. Its segmented RNA genome can lead to the emergence of new or unusual strains in human populations via interspecies transmission and/or reassortment events.RESUMOEste artigo fornece uma revisão sobre imunidade, diagnóstico e aspectos clínicos da doença causada por rotavírus. Também aponta as principais mudanças no perfil epidemiológico da doença diarreica e na diversidade genética das cepas circulantes de rotavírus do grupo A, após a introdução vacinal. O rotavírus do grupo A é o principal patógeno associado à gastroenterite em animais. Seu genoma RNA segmentado pode levar ao surgimento de cepas novas ou incomuns na população humana, por meio de transmissão entre espécies e eventos de rearranjo.

    Full Text Available Currently, the most successful predictive models for activity coefficients are those based on functional groups such as UNIFAC. In contrast, these models require a large amount of experimental data for the determination of their parameter matrix. A more recent alternative is the models based on COSMO, for which only a small set of universal parameters must be calibrated. In this work, a recalibrated COSMO-SAC model was compared with the UNIFAC (Do model employing experimental infinite dilution activity coefficient data for 2236 non-hydrogen-bonding binary mixtures at different temperatures. As expected, UNIFAC (Do presented better overall performance, with a mean absolute error of 0.12 ln-units against 0.22 for our COSMO-SAC implementation. However, in cases involving molecules with several functional groups or when functional groups appear in an unusual way, the deviation for UNIFAC was 0.44 as opposed to 0.20 for COSMO-SAC. These results show that COSMO-SAC provides more reliable predictions for multi-functional or more complex molecules, reaffirming its future prospects.

The teaching-learning process took place with "successive approximations" to the personal, in-group, and theoretical contents, in which knowledge's "raw-material" flowed from the participants' exchange of experiences and life histories, and was concluded with a focal group for further research. On a weekly basis, after the evaluation, everyone expressed feelings regarding "what they had learned and what they were bringing home that day". Among the learned lessons, we can mention the enrichment of the building of "knowing how to be, how to do, and how to live together in the classroom" for the search of knowledge by the ACS. A paradigm was broken in "perceiving that nobody is prepared to teach; it is a challenging adventure, sculptured day by day in the learn-to-learn process". To conclude, it is important to encourage knowledge dissemination by means of a "conversation network", as recommended by Programa Saúde da Família (PSF - Family Health Program, involving all the participants in the health-disease process, thus favouring the ACS's contribution to disease prevention, health promotion and recovery in the community.

    The Guadalquivir estuary is the largest estuarine area on the southern Atlantic coast of Europe; its anthropogenic tidally-restricted marshes are partly within the boundary of the Doñana National Park, southern Spain. Our two-year study describes the spatial and temporal patterns of the fish assemblages in the Doñana marshlands in terms of species richness, abundance and biomass. The main families were Mugilidae and Cyprinidae, which accounted for 40.9% of the total species richness. Unlike the fish assemblages found in other European estuaries, Doñana was dominated in both biomass and abundance by freshwater species, mainly invasive exotic species. The spatial analysis of the assemblage showed four significant fish groups corresponding to different habitats established a priori and related to the salinity gradient. Assemblages did not show a seasonal pattern and the temporal fish groups observed were mainly related to the hydrological cycle and the extreme drought that occurred during the study period.

  10. Evolution of group-wise cooperation: Is direct reciprocity insufficient?

    2017-02-21

    Group-wise cooperation, or cooperation among three or more individuals, is an integral part of human societies. It is likely that group-wise cooperation also played a crucial role in the survival of early hominins, who were confronted with novel environmental challenges, long before the emergence of Homo sapiens. However, previous theoretical and empirical studies, focusing mainly on modern humans, have tended to suggest that evolution of cooperation in sizable groups cannot be explained by simple direct reciprocity and requires some additional mechanisms (reputation, punishment, etc.), which are cognitively too demanding for early hominins. As a partial resolution of the paradox, our recent analysis of a stochastic evolutionary model, which considers the effect of random drift, has revealed that evolution of group-wise cooperation is more likely to occur in larger groups when an individual's share of the benefit produced by one cooperator does not decrease with increasing group size (i.e., goods are non-rivalrous). In this paper, we further extend our previous analysis to explore possible consequences of introducing rare mistakes in behavior or imperfect information about behavior of others on the model outcome. Analyses of the extended models show that evolution of group-wise cooperation can be facilitated by large group size even when individuals intending to cooperate sometimes fail to do so or when all the information about the past behavior of group members is not available. We argue, therefore, that evolution of cooperation in sizable groups does not necessarily require other mechanisms than direct reciprocity if the goods to be produced via group-wise cooperation are non-rivalrous.

    Full Text Available This work reports about the preliminary results and ongoing research based upon profiling collaborative learning groups of persons within the social micro-blogging platforms like Twitter that share potentially common interests on special topic. Hereby the focus is held on spontaneously initiated collaborative learning in Social Media and detection of collaborative learning groups based upon their communication dynamics. Research questions targeted to be answered are: are there any useful data mining algorithms to fulfill the task of pre-selection and clustering of users in social networks, how good do they perform, and what are the metrics that could be used for detection and evaluation in the realm of this task. Basic approach presented here uses as preamble hypothesis that users and their interests in Social Networks can be identified through content generated by them and content they consume. Special focus is held on topic oriented approach as least common bounding point. Those should be also the basic criteria used to detect and outline the learning groups. The aim of this work is to deliver first scientific pre-work for successfully implementation of recommender systems using social network metrics and content features of social network users for the purposes of better learning group communication and information consumption.

    Hypoxia during haemodialysis, mainly acetate, has been reported several times. In our study we have monitored oxygen status during 258 bicarbonate haemodialyses. A significant drop below 80 mmHg in mean oxygen tension occurred. Mean oxygen saturation reflected this drop but did not reach levels...... below 90%. The mean oxygen concentration was on the whole critical low, though slightly increasing during each haemodialysis session due to ultrafiltration. It is concluded that both hypoxia and hypoxaemia do occur during bicarbonate haemodialysis. To a group of patients generally having limited cardiac...... reserves, a poor oxygen status is a potentially serious complication to haemodialysis. Monitoring oxygen status is thus advisable....

Os valores de αsolo foram calculados pela relação entre as radiação solar global refletida e a incidente medidas abaixo do dossel por meio de estações meteorológicas. A inundação da área ocorreu durante fevereiro a junho e posteriormente houve um aumento gradativo de serrapilheira acumulada sobre o solo. O αsolo variou sazonalmente com maiores valores durante o período seco em que houve um aumento de aproximadamente 42% do αsolo em relação ao período com inundação. Análises de correlação cruzada entre o αsolo e precipitação, umidade do solo e a serrapilheira acumulada sobre o solo explicam em parte a influência direta e/ou indireta sobre o αsolo. A precipitação não influenciou diretamente sobre o αsolo do mês atual, enquanto que a umidade do solo influenciou diretamente sobre o αsolo no mês atual e nos seguintes meses, e a serrapilheira acumulada do solo correlacionou-se positivamente com o αsolo indicando influência direta no mês atual.

Foram realizados cálculos de correlação intraclasse ICC para avaliar a confiabilidade do DIM, cálculos da especificidade, sensibilidade e coeficiente de concordância Kappa, respectivamente, para avaliar a validade do DIM em detectar déficits musculares e comparações intragrupos e intergrupos na realização dos quatro testes de força utilizando-se do método ANOVA. RESULTADOS: O DIM demonstrou excelente confiabilidade teste-reteste e validade na avaliação do desempenho muscular dos extensores e flexores do joelho. Na comparação intergrupos. o GTP demonstrou déficits significativamente maiores dos extensores comparados com os grupos GC e GTF. CONCLUSÃO: Dinamômetros isométricos conectados em equipamentos de mecanoterapia podem ser uma alternativa para coletar dados referentes a déficits no desempenho muscular dos extensores e flexores do joelho em indivíduos com reconstrução do LCA.OBJECTIVES: The aim of this study was to evaluate the reliability and validity of a modified isometric dynamometer (MID in performance deficits of the knee extensor and flexor muscles in normal individuals and in those with ACL reconstructions.

    Full Text Available BACKGROUND: Some studies, most of them case-reports, suggest that synesthetes have an advantage in visual search and episodic memory tasks. The goal of this study was to examine this hypothesis in a group study. METHODOLOGY/PRINCIPAL FINDINGS: In the present study, we tested thirteen grapheme-color synesthetes and we compared their performance on a visual search task and a memory test to an age-, handedness-, education-, and gender-matched control group. The results showed no significant group differences (all relevant ps>.50. For the visual search task effect sizes indicated a small advantage for synesthetes (Cohen's d between .19 and .32. No such advantage was found for episodic memory (Cohen's d<.05. CONCLUSIONS/SIGNIFICANCE: The results indicate that synesthesia per se does not seem to lead to a strong performance advantage. Rather, the superior performance of synesthetes observed in some case-report studies may be due to individual differences, to a selection bias or to a strategic use of synesthesia as a mnemonic. In order to establish universal effects of synesthesia on cognition single-case studies must be complemented by group studies.
