  1. Solving the high energy evolution equation including running coupling corrections

    Albacete, Javier L.; Kovchegov, Yuri V.

    2007-01-01

    We study the solution of the nonlinear Balitsky-Kovchegov evolution equation with the recently calculated running coupling corrections [I. I. Balitsky, Phys. Rev. D 75, 014001 (2007). and Y. Kovchegov and H. Weigert, Nucl. Phys. A784, 188 (2007).]. Performing a numerical solution we confirm the earlier result of Albacete et al. [Phys. Rev. D 71, 014003 (2005).] (obtained by exploring several possible scales for the running coupling) that the high energy evolution with the running coupling leads to a universal scaling behavior for the dipole-nucleus scattering amplitude, which is independent of the initial conditions. It is important to stress that the running coupling corrections calculated recently significantly change the shape of the scaling function as compared to the fixed coupling case, in particular, leading to a considerable increase in the anomalous dimension and to a slow-down of the evolution with rapidity. We then concentrate on elucidating the differences between the two recent calculations of the running coupling corrections. We explain that the difference is due to an extra contribution to the evolution kernel, referred to as the subtraction term, which arises when running coupling corrections are included. These subtraction terms were neglected in both recent calculations. We evaluate numerically the subtraction terms for both calculations, and demonstrate that when the subtraction terms are added back to the evolution kernels obtained in the two works the resulting dipole amplitudes agree with each other. We then use the complete running coupling kernel including the subtraction term to find the numerical solution of the resulting full nonlinear evolution equation with the running coupling corrections. Again the scaling regime is recovered at very large rapidity with the scaling function unaltered by the subtraction term

    Full Text Available The family business field of study has grown considerably in recent years in Spain. In fact, it is no exaggeration to say that twenty years ago there was barely any research in this field. In 1992, exactly 25 years ago, a group of family entrepreneurs founded the Instituto de la Empresa Familiar (IEF. IEF created the Chair in Family Business at Spanish universities to foster its inclusion in Business Administration syllabuses and promote its research by Spanish academics. This paper analyses the evolution of research into family businesses carried out by academics who are part of the IEF Network of Chairs, both at international and management level. To do this, the ISI Web of Knowledge database and Scopus were used as sources of information.

  4. Classical evolution and quantum generation in generalized gravity theories including string corrections and tachyons: Unified analyses

    International Nuclear Information System (INIS)

    Hwang, Jai-chan; Noh, Hyerim

    2005-01-01

    We present cosmological perturbation theory based on generalized gravity theories including string theory correction terms and a tachyonic complication. The classical evolution as well as the quantum generation processes in these varieties of gravity theories are presented in unified forms. These apply both to the scalar- and tensor-type perturbations. Analyses are made based on the curvature variable in two different gauge conditions often used in the literature in Einstein's gravity; these are the curvature variables in the comoving (or uniform-field) gauge and the zero-shear gauge. Applications to generalized slow-roll inflation and its consequent power spectra are derived in unified forms which include a wide range of inflationary scenarios based on Einstein's gravity and others

  5. A Thermal Evolution Model of the Earth Including the Biosphere, Continental Growth and Mantle Hydration

    Höning, D.; Spohn, T.

    2014-12-01

    By harvesting solar energy and converting it to chemical energy, photosynthetic life plays an important role in the energy budget of Earth [2]. This leads to alterations of chemical reservoirs eventually affecting the Earth's interior [4]. It further has been speculated [3] that the formation of continents may be a consequence of the evolution life. A steady state model [1] suggests that the Earth without its biosphere would evolve to a steady state with a smaller continent coverage and a dryer mantle than is observed today. We present a model including (i) parameterized thermal evolution, (ii) continental growth and destruction, and (iii) mantle water regassing and outgassing. The biosphere enhances the production rate of sediments which eventually are subducted. These sediments are assumed to (i) carry water to depth bound in stable mineral phases and (ii) have the potential to suppress shallow dewatering of the underlying sediments and crust due to their low permeability. We run a Monte Carlo simulation for various initial conditions and treat all those parameter combinations as success which result in the fraction of continental crust coverage observed for present day Earth. Finally, we simulate the evolution of an abiotic Earth using the same set of parameters but a reduced rate of continental weathering and erosion. Our results suggest that the origin and evolution of life could have stabilized the large continental surface area of the Earth and its wet mantle, leading to the relatively low mantle viscosity we observe at present. Without photosynthetic life on our planet, the Earth would be geodynamical less active due to a dryer mantle, and would have a smaller fraction of continental coverage than observed today.

    The unexpected diversity of exoplanets includes a growing number of super-Earth planets, i.e., exoplanets with masses of up to several Earth masses and a similar chemical and mineralogical composition as Earth. We present a thermal evolution model for a 10 Earth-mass planet orbiting a star like the Sun. Our model is based on the integrated system approach, which describes the photosynthetic biomass production and takes into account a variety of climatological, biogeochemical, and geodynamical processes. This allows us to identify a so-called photosynthesis-sustaining habitable zone (pHZ), as determined by the limits of biological productivity on the planetary surface. Our model considers solar evolution during the main-sequence stage and along the Red Giant Branch as described by the most recent solar model. We obtain a large set of solutions consistent with the principal possibility of life. The highest likelihood of habitability is found for "water worlds." Only mass-rich water worlds are able to realize pHZ-type habitability beyond the stellar main sequence on the Red Giant Branch.

  8. Evolution of a Greenland Ice sheet Including Shelves and Regional Sea Level Variations

    Observational evidence, including offshore moraines and marine sediment cores infer that at the Last Glacial maximum (LGM) the Greenland ice sheet (GIS) grounded out across the Davis Strait into Baffin Bay, with fast flowing ice streams extending out to the continental shelf break along the NW margin. These observations lead to a number of questions as to weather the GIS and Laurentide ice sheet (LIS) coalesced during glacial maximums, and if so, did a significant ice shelf develop across Baffin Bay and how would such a configuration impact on the relative contribution of these ice sheets to eustatic sea level (ESL). Most previous paleo ice sheet modelling simulations of the GIS recreated an ice sheet that either did not extend out onto the continental shelf or utilised a simplified marine ice parameterisation to recreate an extended GIS, and therefore did not fully include ice shelf dynamics. In this study we simulate the evolution of the GIS from 220 kyr BP to present day using IMAU-ice; a 3D thermodynamical ice sheet model which fully accounts for grounded and floating ice, calculates grounding line migration and ice shelf dynamics. As there are few observational estimates of the long-term (yrs) sub marine basal melting rates (mbm) for the GIS, we developed a mbm parameterization within IMAU-ice controlled primarily by changes in paleo water depth. We also investigate the influence of the LIS on the GIS evolution by including relative sea level forcing's derived from a Glacial Isostatic Adjustment model. We will present results of how changes in the mbm directly impacts on the ice sheet dynamics, timing and spatial extent of the GIS at the glacial maximums, but also on the rate of retreat and spatial extent at the Last interglacial (LIG) minimum. Results indicate that with the inclusion of ice shelf dynamics, a larger GIS is generated which is grounded out into Davis strait, up to a water depth of -750 m, but significantly reduces the GIS contribution to Last

  11. A theory of evolution that includes prebiotic self-organization and episodic species formation.

    Science.gov (United States)

    Davis, B K

    1996-01-01

    A theory has been proposed that encompasses pre-replication changes in RNA synthesis and non-gradual variant formation, in addition to competitive replication. Using a fundamental theorem of natural selection and maximum principle scaled to nucleotide condensation, evolution in vitro was demonstrated to maximally damp both kinetic and thermodynamic forces driving this reaction, from its pre-replication stage. This led to the finding that evolution follows a path of least action. These principles form the framework for a general theory of evolution, whose scope extends beyond evolution modeled by synthesis of non-interacting RNA molecules. It applies, in particular, to standard processes, such as competitive crystallization. In calculations simulating de novo formation of self-replicating RNA molecules in the Qbeta replicase system, spontaneous changes in strand secondary structure promoted the transition from random copolymerization to template-directed polymerization. This finding indicates selection preceded genome self-propagation. Non-gradual species formation was attributed to the presence of heterogeneous thermodynamic forces. Growth unconstrained by competition follows mutation to a variant able to utilize a free energy source alien to its progenitors. Evolution in a heterogeneous system can, therefore, exhibit discontinuous rates of species formation and spawn new species populations. Natural selection among competing self-propagators thus gives way to a principle of wider scope stating that evolution optimally damps the physicochemical forces causing change within an evolving system.

    1980-01-01

    Accurate estimates of convective and radiative heat transfer in the magnetohydrodynamic channel are provided. Calculations performed for a base load-size channel indicate that heat transfer by gas radiation almost equals that by convection for smooth walls, and amounts to 70% as much as the convective heat transfer for rough walls. Carbon dioxide, water vapor, and potassium atoms are the principal participating gases. The evolution of slag particles by homogeneous nucleation and condensation is also investigated. The particle-size spectrum so computed is later utilized to analyze the radiation enhancement by slag particles in the MHD diffuser. The impact of the slag particle spectrum on the selection of a workable and design of an efficient seed collection system is discussed.

    The visual system is tuned for rapid detection of faces, with the fastest choice saccade to a face at 100ms. Familiar faces have a more robust representation than do unfamiliar faces, and are detected faster in the absence of awareness and with reduced attentional resources. Faces of family and close friends become familiar over a protracted period involving learning the unique visual appearance, including a view-invariant representation, as well as person knowledge. We investigated the effect of personal familiarity on the earliest stages of face processing by using a saccadic-choice task to measure how fast familiar face detection can happen. Subjects made correct and reliable saccades to familiar faces when unfamiliar faces were distractors at 180ms—very rapid saccades that are 30 to 70ms earlier than the earliest evoked potential modulated by familiarity. By contrast, accuracy of saccades to unfamiliar faces with familiar faces as distractors did not exceed chance. Saccades to faces with object distractors were even faster (110 to 120 ms) and equivalent for familiar and unfamiliar faces, indicating that familiarity does not affect ultra-rapid saccades. We propose that detectors of diagnostic facial features for familiar faces develop in visual cortices through learning and allow rapid detection that precedes explicit recognition of identity.

  18. Computer simulation of evolution and interaction dynamics of the vortex structures in fluids including atmosphere and hydrosphere

    Science.gov (United States)

    Belashov, Vasily

    We study numerically the interaction of the vortex structures in the continuum, and, specifically, in fluids and plasmas in two-dimensional approximation, when the Euler-type equations are applicable, namely: begin{center} e_{i}d_{t}x_{i}=d_{y}_{i}H/B, e_{i}d_{t}y_{i}=-d_{x}_{i}H/B, d_{m}=d/dm; d_{t}rho+vnablarho=0, v= - [z, nablapsi]/B; Deltapsi - f = - phi where e_{i} is the strength (circulation) of discrete vortex or the charge per unit length of the filaments, phi is a z-component of vorticity zeta or charge density rho, and psi is a stream function or potential for the two-dimensional flow of inviscid fluid and guiding-centre plasma, respectively, and H is a Hamiltonian. Note, that in the continuum (fluid) model B=1 in the Hamiltonian eqs. Function f=0 for the continuum or quasi-particles (filaments) with Coulomb interaction models, and f=k(2) psi for a screened Coulomb interaction model. We consider here only case f=0, and generalization of our approximation for f=k(2) psi is rather trivial. For numerical simulation we used the contour dynamics method, to some extent modified. We fulfilled a number of the series of numerical simulations for study of two-vortex inter-action, the interaction in the N-vortex systems, including interaction between the vortex structures and the dust particles, and also interaction of two three-dimensional plane-rotating vortex structures within the framework of many-layer model of medium, in dependence on some parameters: initial distance between vortices, value and sign of their vorticities, and spatial configuration of the vortex system. The results obtained showed that for all cases in dependence on initial conditions two regimes of the interaction can be observed, namely: weak interaction with quasi-stationary evolution and active interaction with the "phase intermixing", when the evolution can lead to formation of complex forms of vorticity regions. The theoretical explanation of the effects, which we observed, is given on

  19. Familiarity in Source Memory

    Mollison, Matthew V.; Curran, Tim

    2012-01-01

    Familiarity and recollection are thought to be separate processes underlying recognition memory. Event-related potentials (ERPs) dissociate these processes, with an early (approximately 300–500 ms) frontal effect relating to familiarity (the FN400) and a later (500–800 ms) parietal old/new effect relating to recollection. It has been debated whether source information for a studied item (i.e., contextual associations from when the item was previously encountered) is only accessible through recollection, or whether familiarity can contribute to successful source recognition. It has been shown that familiarity can assist in perceptual source monitoring when the source attribute is an intrinsic property of the item (e.g., an object’s surface color), but few studies have examined its contribution to recognizing extrinsic source associations. Extrinsic source associations were examined in three experiments involving memory judgments for pictures of common objects. In Experiment 1, source information was spatial and results suggested that familiarity contributed to accurate source recognition: the FN400 ERP component showed a source accuracy effect, and source accuracy was above chance for items judged to only feel familiar. Source information in Experiment 2 was an extrinsic color association; source accuracy was at chance for familiar items and the FN400 did not differ between correct and incorrect source judgments. Experiment 3 replicated the results using a within-subjects manipulation of spatial vs. color source. Overall, the results suggest that familiarity’s contribution to extrinsic source monitoring depends on the type of source information being remembered. PMID:22789677

  20. TWO-DIMENSIONAL STELLAR EVOLUTION CODE INCLUDING ARBITRARY MAGNETIC FIELDS. II. PRECISION IMPROVEMENT AND INCLUSION OF TURBULENCE AND ROTATION

    In the second paper of this series we pursue two objectives. First, in order to make the code more sensitive to small effects, we remove many approximations made in Paper I. Second, we include turbulence and rotation in the two-dimensional framework. The stellar equilibrium is described by means of a set of five differential equations, with the introduction of a new dependent variable, namely the perturbation to the radial gravity, that is found when the nonradial effects are considered in the solution of the Poisson equation. Following the scheme of the first paper, we write the equations in such a way that the two-dimensional effects can be easily disentangled. The key concept introduced in this series is the equipotential surface. We use the underlying cause-effect relation to develop a recurrence relation to calculate the equipotential surface functions for uniform rotation, differential rotation, rotation-like toroidal magnetic fields, and turbulence. We also develop a more precise code to numerically solve the two-dimensional stellar structure and evolution equations based on the equipotential surface calculations. We have shown that with this formulation we can achieve the precision required by observations by appropriately selecting the convergence criterion. Several examples are presented to show that the method works well. Since we are interested in modeling the effects of a dynamo-type field on the detailed envelope structure and global properties of the Sun, the code has been optimized for short timescales phenomena (down to 1 yr). The time dependence of the code has so far been tested exclusively to address such problems.

  1. Analytic model for the long-term evolution of circular Earth satellite orbits including lunar node regression

    This paper aims to obtain an analytic approximation to the evolution of circular orbits governed by the Earth's J2 and the luni-solar gravitational perturbations. Assuming that the lunar orbital plane coincides with the ecliptic plane, Allan and Cook (Proc. R. Soc. A, Math. Phys. Eng. Sci. 280(1380):97, 1964) derived an analytic solution to the orbital plane evolution of circular orbits. Using their result as an intermediate solution, we establish an approximate analytic model with lunar orbital inclination and its node regression be taken into account. Finally, an approximate analytic expression is derived, which is accurate compared to the numerical results except for the resonant cases when the period of the reference orbit approximately equals the integer multiples (especially 1 or 2 times) of lunar node regression period.

El aumento de la esperanza de vida y la disminución de la fecundidad conllevan un debilitamiento de las estructuras familiares tradicionales entre las diversas generaciones. Ha aumentado la diversidad en las formas familiares, valores, normas, y costumbres. La prolongación de la vida y la coexistencia de varias generaciones permite poder detentar durante más años los diversos estatus y roles familiares. A pesar de los cambios en las relaciones familiares, de la investigación existente se desprende que la familia sigue siendo una institución social fundamental en el apoyo a las personas que lo necesitan, y en cuyo seno todavía se sigue practicando el intercambio de bienes y servicios –como el cuidado, entre otros—entre las generaciones. Es la permanencia en las sociedades contemporáneas de la solidaridad familiar intergeneracional. En ese contexto se presentan diversos resultados derivados de la investigación europea Old Age and Autonomy: The Role of Social Services System and Intergenerational Family Solidarity.Ageing is a feature of modern societies. The increase in life expectancy, together with the decrease in fertility rates in Western societies, is leading to the weakening of traditional intergenerational family structures. The diversity in family forms, values, norms, and behaviours has increased. The coexistence of several generations allows family members to maintain longer the different family statuses and roles. Despite social changes in family relations, existing research shows that the family continues to be a fundamental social institution in the support of persons in need of it. Transfers of goods and services –including care- continues to be common practice within families, showing that intergenerational family solidarity remains a feature in contemporary societies.

    Here we provide the first report about the rates of muscle evolution derived from Bayesian and parsimony cladistic analyses of primate higher-level phylogeny, and compare these rates with published rates of molecular evolution. It is commonly accepted that there is a ‘general molecular slow-down of hominoids’, but interestingly the rates of muscle evolution in the nodes leading and within the hominoid clade are higher than those in the vast majority of other primate clades. The rate of muscle evolution at the node leading to Homo (1.77) is higher than that at the nodes leading to Pan (0.89) and particularly to Gorilla (0.28). Notably, the rates of muscle evolution at the major euarchontan and primate nodes are different, but within each major primate clade (Strepsirrhini, Platyrrhini, Cercopithecidae and Hominoidea) the rates at the various nodes, and particularly at the nodes leading to the higher groups (i.e. including more than one genera), are strikingly similar. We explore the implications of these new data for the tempo and mode of primate and human evolution. PMID:23320764

    Employees working across multiple cultures are exposed to a vast number of different norms and values, and consequentially work is often a struggle to retain a coherent sense of self. However, when international workers travel, they also encounter more bland spaces where familiarity and similarity...... are important. These spaces appear culturally generic to the Western traveler, but are highly Westernized to bring comfort to Western employees traveling in foreign cultures. This paper argues that these spaces are important in cross-cultural identity work in the sense that international workers – professional...... strangers – need these places to belong and relate to familiarity and to regain a sense of identity. Drawing on an illustrative empirical vignette of an international consultant, I demonstrate how culturally generic spaces can be used in identity work of an international relations consultant....

    Full Text Available The identity of most functional elements in the mammalian genome and the phenotypes they impact are unclear. Here, we perform a genome-wide comparative analysis of patterns of accelerated evolution in species with highly distinctive traits to discover candidate functional elements for clinically important phenotypes. We identify accelerated regions (ARs in the elephant, hibernating bat, orca, dolphin, naked mole rat, and thirteen-lined ground squirrel lineages in mammalian conserved regions, uncovering ∼33,000 elements that bind hundreds of different regulatory proteins in humans and mice. ARs in the elephant, the largest land mammal, are uniquely enriched near elephant DNA damage response genes. The genomic hotspot for elephant ARs is the E3 ligase subunit of the Fanconi anemia complex, a master regulator of DNA repair. Additionally, ARs in the six species are associated with specific human clinical phenotypes that have apparent concordance with overt traits in each species.

    Full Text Available The Tempio della Consolazione in Todi (16th cent. has always been one of the most significant symbols of the Umbrian landscape. Since the first times after its completion (1606 the structure has exhibited evidences of instability, due to foundation subsiding and/or seismic activity. Structural and geotechnical countermeasures have been undertaken on the Tempio and its surroundings from the 17th century until recent times. Until now a truly satisfactory analysis of the overall deformation and attitude of the building has not been performed, since the existing surveys record the overhangs of the pillars, the crack pattern or the subsidence over limited time spans. Describing the attitude of the whole church is in fact a complex operation due to the architectural character of the building, consisting of four apses (three polygonal and one semicircular covered with half domes, which surround the central area with the large dome. The present research aims to fill the gap of knowledge with a global study based on geomatic techniques for an accurate 3D reconstruction of geometry and attitude, integrated with a historical research on damage and interventions and a geotechnical analysis. The geomatic survey results from the integration of different techniques: GPS-GNSS for global georeferencing, laser scanning and digital photogrammetry for an accurate 3D reconstruction, high precision total station and geometric leveling for a direct survey of deformations and cracks, and for the alignment of the laser scans. The above analysis allowed to assess the dynamics of the cracks occurred in the last 25 years by a comparison with a previous survey. From the photographic colour associated to the point cloud was also possible to map the damp patches showing on the domes intrados, mapping their evolution over the last years.

    Full Text Available El objetivo es identificar las valoraciones sobre el cuidado no familiar desde la perspectiva de ancianos residentes en comunidad en condiciones de pobreza. Se realizó un estudio multicéntrico con metodología cualitativa con 92 ancianos residentes en cuatro estados en México de 2002 a 2004. Se realizaron entrevistas semi-estructuradas en los hogares de los ancianos y se hizo un análisis de contenido. La expectativa de los ancianos es ser cuidados por sus hijos en sus hogares, sin embargo, este cuidado familiar no se da cuando existen rupturas en el sistema de reciprocidad entre las generaciones. En estas condiciones, el cuidado por extraños en el hogar o la institucionalización en un asilo es la opción para estos ancianos. Ambas opciones son valoradas negativamente, la primera porque no reúne los rasgos del cuidado otorgado por los hijos, y en el asilo porque no existe realmente un cuidado.

  10. Mitochondrial DNA sequence evolution and phylogeny of the Atlantic Alcidae, including the extinct great auk (Pinguinus impennis).

    The Atlantic auk assemblage includes four extant species, razorbill (Alca torda), dovekie (Alle alle), common murre (Uria aalge), and thick-billed murre (U. lomvia), and one recently extinct species, the flightless great auk (Pinguinus impennis). To determine the phylogenetic relationships among the species, a contiguous 4.2-kb region of the mitochondrial genome from the extant species was amplified using PCR. This region included one ribosomal RNA gene, four transfer RNA genes, two protein-coding genes, the control region, and intergenic spacers. Sets of PCR primers for amplifying the same region from great auk were designed from sequences of the extant species. The authenticity of the great auk sequence was ascertained by alternative amplifications, cloning, and separate analyses in an independent laboratory. Phylogenetic analyses of the entire assemblage, made possible by the great auk sequence, fully resolved the phylogenetic relationships and split it into two primary lineages, Uria versus Alle, Alca, and Pinguinus. A sister group relationship was identified between Alca and Pinguinus to the exclusion of ALLE: Phylogenetically, the flightless great auk originated late relative to other divergences within the assemblage. This suggests that three highly divergent species in terms of adaptive specializations, Alca, Alle, and Pinguinus, evolved from a single lineage in the Atlantic Ocean, in a process similar to the initial adaptive radiation of alcids in the Pacific Ocean.

    AimTo review outcomes and local evolution of treated lesions following percutaneous image-guided screw fixation (PIGSF) of pathological/insufficiency fractures (PF/InF) and impeding fractures (ImF) in cancer patients at two tertiary centres.Materials and methodsThirty-two consecutive patients (mean age 67.5 years; range 33–86 years) with a range of tumours and prognoses underwent PIGSF for non/minimally displaced PF/InF and ImF. Screws were placed under CT/fluoroscopy or cone-beam CT guidance, with or without cementoplasty. Clinical outcomes were assessed using a simple 4-point scale (1 = worse; 2 = stable; 3 = improved; 4 = significantly improved). Local evolution was reviewed on most recent follow-up imaging. Technical success, complications, and overall survival were evaluated.ResultsThirty-six lesions were treated with 74 screws mainly in the pelvis and femoral neck (58.2 %); including 47.2 % PF, 13.9 % InF, and 38.9 % ImF. Cementoplasty was performed in 63.9 % of the cases. Technical success was 91.6 %. Hospital stay was ≤3 days; 87.1 % of lesions were improved at 1-month follow-up; three major complications (early screw-impingement radiculopathy; accelerated coxarthrosis; late coxofemoral septic arthritis) and one minor complication were observed. Unfavourable local evolution at imaging occurred in 3/24 lesions (12.5 %) at mean 8.7-month follow-up, including poor consolidation (one case) and screw loosening (two cases, at least 1 symptomatic). There were no cases of secondary fractures.ConclusionsPIGSF is feasible for a wide range of oncologic patients, offering good short-term efficacy, acceptable complication rates, and rapid recovery. Unfavourable local evolution at imaging may be relatively frequent, and requires close clinico-radiological surveillance.

    Full Text Available El nevus blanco esponjoso (NBE es una rara condición autosómica dominante, caracterizada por placas blancas bilaterales en la mucosa, de aspecto esponjoso, blandas a la palpación y que pueden escamarse. Los tratamientos son paliativos; y el uso de antibióticos, en especial la tetraciclina, ha demostrando buenos resultados en su control. Este trabajo presenta tres casos clínicos de una familia afectada por NBE, donde se discuten los posibles diagnósticos diferenciales y conductas terapéuticas indicadas. Un paciente masculino de 52 años de edad acudió a la clínica aquejado de lesiones blancas bilaterales. El paciente notó las lesiones 30 años antes, sin lograr un diagnóstico final de las mismas. Después de la anamnesis y del examen clínico fue realizada una biopsia incisional. La reunión de los datos clínicos e histopatológicos llevó al diagnóstico de NBE. Se le solicitó al paciente que indagase entre sus familiares con respecto a lesiones semejantes. Se detectó que el hijo de 19 años y la hija de 25 eran portadores de placas blancas en la mucosa yugal. Como no había afectación estética, se optó por no intervenir en las lesiones. El nevus blanco esponjoso es una lesión genética que debe ser diferenciada de otras patologías localizadas y sistémicas importantes, que tienen repercusiones serias para el individuo. Como no hay un tratamiento curativo para el NBE, el papel del cirujano dentista es diagnosticar esta lesión, aclarar al paciente sobre la naturaleza benigna y autolimitante del NBE y si fuera necesario desde el punto de vista estético, aplicar diferentes modalidades terapéuticas.

  17. Familiarity facilitates feature-based face processing

    Wheeler, Kelsey G.; Cipolli, Carlo; Gobbini, M. Ida

    2017-01-01

    Recognition of personally familiar faces is remarkably efficient, effortless and robust. We asked if feature-based face processing facilitates detection of familiar faces by testing the effect of face inversion on a visual search task for familiar and unfamiliar faces. Because face inversion disrupts configural and holistic face processing, we hypothesized that inversion would diminish the familiarity advantage to the extent that it is mediated by such processing. Subjects detected personally familiar and stranger target faces in arrays of two, four, or six face images. Subjects showed significant facilitation of personally familiar face detection for both upright and inverted faces. The effect of familiarity on target absent trials, which involved only rejection of unfamiliar face distractors, suggests that familiarity facilitates rejection of unfamiliar distractors as well as detection of familiar targets. The preserved familiarity effect for inverted faces suggests that facilitation of face detection afforded by familiarity reflects mostly feature-based processes. PMID:28582439

  18. The familiar versus the unfamiliar: Familiarity bias amongst individual investors

    2017-02-01

    Full Text Available Purpose: The purpose of this study was to investigate the existence of familiarity bias amongst individual investors in the South African stock market. Problem investigated: According to Warren Buffet, one needs to maintain emotional detachment if one wants to be a successful investor. However, recent research indicates that the perceptions of companies’ products and brands may influence individuals’ investment decisions in the stock market. This phenomenon implies that the investment decisions of individual investors are not purely based on firm fundamentals as suggested by traditional finance theories, but might be driven partly by the positive or negative attitude they have towards certain companies’ products and brands. The existence of familiarity bias amongst individual investors was investigated to determine if individuals prefer to invest in companies they are familiar with as opposed to unfamiliar companies. Methodology: A quantitative approach was followed. An online survey was used to show images of familiar and unfamiliar company brands to respondents, whereafter respondents were asked to indicate whether they will invest in the shares of the identified companies. The statistical analysis entailed descriptive statistics as well as one-way analyses of variance to test the stated hypotheses. Main findings: The results of this exploratory study indicate that investors do exhibit familiarity bias when choosing between different companies to invest in. Value of the research: The inclination of individual investors to invest in familiar corporate brands can have implications for the marketing industry, financial markets, the performance of companies as well as the investment performance of individual investors in the sense that it would seem that company brands could have an influence on investment decisions.

  20. Energy evolution of the moments of the hadron distribution in QCD jets including NNLL resummation and NLO running-coupling corrections

    CERN Document Server

    Perez-Ramos, Redamy

    2014-01-01

    The moments of the single inclusive momentum distribution of hadrons in QCD jets, are studied in the next-to-modified-leading-log approximation (NMLLA) including next-to-leading-order (NLO) corrections to the alpha_s strong coupling. The evolution equations are solved using a distorted Gaussian parametrisation, which successfully reproduces the spectrum of charged hadrons of jets measured in e+e- collisions. The energy dependencies of the maximum peak, multiplicity, width, kurtosis and skewness of the jet hadron distribution are computed analytically. Comparisons of all the existing jet data measured in e+e- collisions in the range sqrt(s)~2-200 GeV to the NMLLA+NLO* predictions allow one to extract a value of the QCD parameter Lambda_QCD, and associated two-loop coupling constant at the Z resonance alpha_s(m_Z^2)= 0.1195 +/- 0.0022, in excellent numerical agreement with the current world average obtained using other methods.

  1. A Familiar(ity Problem: Assessing the Impact of Prerequisites and Content Familiarity on Student Learning.

    Directory of Open Access Journals (Sweden)

    Justin F Shaffer

    Full Text Available Prerequisites are embedded in most STEM curricula. However, the assumption that the content presented in these courses will improve learning in later courses has not been verified. Because a direct comparison of performance between students with and without required prerequisites is logistically difficult to arrange in a randomized fashion, we developed a novel familiarity scale, and used this to determine whether concepts introduced in a prerequisite course improved student learning in a later course (in two biology disciplines. Exam questions in the latter courses were classified into three categories, based on the degree to which the tested concept had been taught in the prerequisite course. If content familiarity mattered, it would be expected that exam scores on topics covered in the prerequisite would be higher than scores on novel topics. We found this to be partially true for "Very Familiar" questions (concepts covered in depth in the prerequisite. However, scores for concepts only briefly discussed in the prerequisite ("Familiar" were indistinguishable from performance on topics that were "Not Familiar" (concepts only taught in the later course. These results imply that merely "covering" topics in a prerequisite course does not result in improved future performance, and that some topics may be able to removed from a course thereby freeing up class time. Our results may therefore support the implementation of student-centered teaching methods such as active learning, as the time-intensive nature of active learning has been cited as a barrier to its adoption. In addition, we propose that our familiarity system could be broadly utilized to aid in the assessment of the effectiveness of prerequisites.

    Full Text Available The importance of music in our daily life has given rise to an increased number of studies addressing the brain regions involved in its appreciation. Some of these studies controlled only for the familiarity of the stimuli, while others relied on pleasantness ratings, and others still on musical preferences. With a listening test and a functional magnetic resonance imaging (fMRI experiment, we wished to clarify the role of familiarity in the brain correlates of music appreciation by controlling, in the same study, for both familiarity and musical preferences. First, we conducted a listening test, in which participants rated the familiarity and liking of song excerpts from the pop/rock repertoire, allowing us to select a personalized set of stimuli per subject. Then, we used a passive listening paradigm in fMRI to study music appreciation in a naturalistic condition with increased ecological value. Brain activation data revealed that broad emotion-related limbic and paralimbic regions as well as the reward circuitry were significantly more active for familiar relative to unfamiliar music. Smaller regions in the cingulate cortex and frontal lobe, including the motor cortex and Broca's area, were found to be more active in response to liked music when compared to disliked one. Hence, familiarity seems to be a crucial factor in making the listeners emotionally engaged with music, as revealed by fMRI data.

    The human voice is described in dialogic linguistics as an embodiment of self in a social context, contributing to expression, perception and mutual exchange of self, consciousness, inner life, and personhood. While these approaches are subjective and arise from phenomenological perspectives, scientific facts about personal vocal identity, and its role in biological development, support these views. It is our purpose to review studies of the biology of personal vocal identity -- the familiar voice pattern-- as providing an empirical foundation for the view that the human voice is an embodiment of self in the social context. Recent developments in the biology and evolution of communication are concordant with these notions, revealing that familiar voice recognition (also known as vocal identity recognition or individual vocal recognition) or contributed to survival in the earliest vocalizing species. Contemporary ethology documents the crucial role of familiar voices across animal species in signaling and perceiving internal states and personal identities. Neuropsychological studies of voice reveal multimodal cerebral associations arising across brain structures involved in memory, emotion, attention, and arousal in vocal perception and production, such that the voice represents the whole person. Although its roots are in evolutionary biology, human competence for processing layered social and personal meanings in the voice, as well as personal identity in a large repertory of familiar voice patterns, has achieved an immense sophistication.

    Ceraceosorus bombacis is an early-diverging lineage of smut fungi and a pathogen of cotton trees (Bombax ceiba). To study the evolutionary genomics of smut fungi in comparison with other fungal and oomycete pathogens, the genome of C. bombacis was sequenced and comparative genomic analyses were performed. The genome of 26.09 Mb encodes for 8,024 proteins, of which 576 are putative-secreted effector proteins (PSEPs). Orthology analysis revealed 30 ortholog PSEPs among six Ustilaginomycotina genomes, the largest groups of which are lytic enzymes, such as aspartic peptidase and glycoside hydrolase. Positive selection analyses revealed the highest percentage of positively selected PSEPs in C. bombacis compared with other Ustilaginomycotina genomes. Metabolic pathway analyses revealed the absence of genes encoding for nitrite and nitrate reductase in the genome of the human skin pathogen Malassezia globosa, but these enzymes are present in the sequenced plant pathogens in smut fungi. Interestingly, these genes are also absent in cultivable oomycete animal pathogens, while nitrate reductase has been lost in cultivable oomycete plant pathogens. Similar patterns were also observed for obligate biotrophic and hemi-biotrophic fungal and oomycete pathogens. Furthermore, it was found that both fungal and oomycete animal pathogen genomes are lacking cutinases and pectinesterases. Overall, these findings highlight the parallel evolution of certain genomic traits, revealing potential common evolutionary trajectories among fungal and oomycete pathogens, shaping the pathogen genomes according to their lifestyle. © The Author(s) 2015.

    2014-10-01

    Congenital amusia has been described as a lifelong deficit of music perception and production, notably including amusic individuals' difficulties to recognize a familiar tune without the aid of lyrics. The present study aimed to evaluate whether amusic individuals might have acquired long-term knowledge of familiar music, and to test for the minimal amount of acoustic information necessary to access this knowledge (if any) in amusia. Segments of familiar and unfamiliar instrumental musical pieces were presented with increasing duration (250, 500, 1000 msec etc.), and participants provided familiarity judgments for each segment. Results showed that amusic individuals succeeded in differentiating familiar from unfamiliar excerpts with as little acoustic information as did control participants (i.e., within 500 msec). The findings reveal that amusic individuals have stored musical pieces in long-term memory (LTM), and, together with other recent findings, they suggest that congenital amusia might impair conscious access to music processing rather than music processing per se.

    Full Text Available Estudios previos han demostrado que las empresas familiares son muy diferentes a las no familiares, puesto que su carácter familiar y la relación familia-empresa les imprime unos rasgos y una cultura propia que le suponen cualidades diferenciadoras. De igual forma, la identificación de una estructura financiera y una jerarquía financiera única en el caso de las empresas familiares nos conduce a plantear una investigación en torno a la existencia de una cultura financiera propia de las empresas familiares. Para ello, se ha llevado a cabo un análisis de corte transversal mediante una encuesta dirigida a una muestra representativa de 837 empresas. Los resultados confirman que el carácter de la empresa es un factor discriminante de la cultura financiera al presentar las empresas familiares un menor grado de cultura financiera que las empresas no familiares. De forma que las empresas familiares se apoyan en menor medida que las no familiares en la opinión de sus directores financieros para las decisiones gerenciales en el área de financiación, están menos informadas de las fuentes financieras alternativas a las tradicionales y la importancia que le conceden a la formación del departamento de administración y financiero es también menor.

    Estudios previos han demostrado que las empresas familiares son muy diferentes a las no familiares, puesto que su carácter familiar y la relación familia-empresa les imprime unos rasgos y una cultura propia que le suponen cualidades diferenciadoras. De igual forma, la identificación de una estructura financiera y una jerarquía financiera única en el caso de las empresas familiares nos conduce a plantear una investigación en torno a la existencia de una cultura financiera propia de las empresa...

  13. A two-phase debris-flow model that includes coupled evolution of volume fractions, granular dilatancy, and pore-fluid pressure

    Pore-fluid pressure plays a crucial role in debris flows because it counteracts normal stresses at grain contacts and thereby reduces intergranular friction. Pore-pressure feedback accompanying debris deformation is particularly important during the onset of debrisflow motion, when it can dramatically influence the balance of forces governing downslope acceleration. We consider further effects of this feedback by formulating a new, depth-averaged mathematical model that simulates coupled evolution of granular dilatancy, solid and fluid volume fractions, pore-fluid pressure, and flow depth and velocity during all stages of debris-flow motion. To illustrate implications of the model, we use a finite-volume method to compute one-dimensional motion of a debris flow descending a rigid, uniformly inclined slope, and we compare model predictions with data obtained in large-scale experiments at the USGS debris-flow flume. Predictions for the first 1 s of motion show that increasing pore pressures (due to debris contraction) cause liquefaction that enhances flow acceleration. As acceleration continues, however, debris dilation causes dissipation of pore pressures, and this dissipation helps stabilize debris-flow motion. Our numerical predictions of this process match experimental data reasonably well, but predictions might be improved by accounting for the effects of grain-size segregation.

    Fossils and other paleontological information can improve phylogenetic comparative method estimates of phenotypic evolution and generate hypotheses related to species diversification. Here, we use fossil information to calibrate ancestral reconstructions of suitable climate for Sceloporus lizards in North America. Integrating data from the fossil record, general circulation models of paleoclimate during the Miocene, climate envelope modeling, and phylogenetic comparative methods provides a geographically and temporally explicit species distribution model of Sceloporus-suitable habitat through time. We provide evidence to support the historic biogeographic hypothesis of Sceloporus diversification in warm North American deserts and suggest a relatively recent Sceloporus invasion into Mexico around 6 Ma. We use a physiological model to map extinction risk. We suggest that the number of hours of restriction to a thermal refuge limited Sceloporus from inhabiting Mexico until the climate cooled enough to provide suitable habitat at approximately 6 Ma. If the future climate returns to the hotter climates of the past, Mexico, the place of highest modern Sceloporus richness, will no longer provide suitable habitats for Sceloporus to survive and reproduce.

    Full Text Available Este trabajo analiza las implicaciones del concepto "familia" señalando la multiplicidad de fenómenos y situaciones incluidos en el mismo. Su elucidación permitirá determinar los diversos tipos de familia y de riesgo que podemos encontrar en nuestro trabajo cotidiano. La evolución de ese concepto está directamente influida por las determinantes socioestructurales y culturales que en cada momento histórico contextualizan a los sujetos, así como las posibles situaciones de riesgo que deben enfrentar y los recursos con los que cuentan. Se analiza la influencia de las representaciones acerca de cómo debe ser una familia, en la actualidad las familias presentan diferentes formas o estructuras y ello no implica el cumplimiento o no de sus funciones. Esto permitirá establecer adecuadamente las diferentes estrategias de prevención y abordaje aplicables a cada situación. Se ejemplificará concretamente con situaciones problemáticas relacionados a los casos de violencia familiar y maltrato infantil, concretamente con la negligencia y el abuso sexual infantil.

    We investigated whether personally familiar faces are preferentially processed in conditions of reduced attentional resources and in the absence of conscious awareness. In the first experiment, we used Rapid Serial Visual Presentation (RSVP) to test the susceptibility of familiar faces and faces of strangers to the attentional blink. In the second experiment, we used continuous flash interocular suppression to render stimuli invisible and measured face detection time for personally familiar faces as compared to faces of strangers. In both experiments we found an advantage for detection of personally familiar faces as compared to faces of strangers. Our data suggest that the identity of faces is processed with reduced attentional resources and even in the absence of awareness. Our results show that this facilitated processing of familiar faces cannot be attributed to detection of low-level visual features and that a learned unique configuration of facial features can influence preconscious perceptual processing.

  18. LIDT-DD: A new self-consistent debris disc model that includes radiation pressure and couples dynamical and collisional evolution

    2013-10-01

    Context. In most current debris disc models, the dynamical and the collisional evolutions are studied separately with N-body and statistical codes, respectively, because of stringent computational constraints. In particular, incorporating collisional effects (especially destructive collisions) into an N-body scheme has proven a very arduous task because of the exponential increase of particles it would imply. Aims: We present here LIDT-DD, the first code able to mix both approaches in a fully self-consistent way. Our aim is for it to be generic enough to be applied to any astrophysical case where we expect dynamics and collisions to be deeply interlocked with one another: planets in discs, violent massive breakups, destabilized planetesimal belts, bright exozodiacal discs, etc. Methods: The code takes its basic architecture from the LIDT3D algorithm for protoplanetary discs, but has been strongly modified and updated to handle the very constraining specificities of debris disc physics: high-velocity fragmenting collisions, radiation-pressure affected orbits, absence of gas that never relaxes initial conditions, etc. It has a 3D Lagrangian-Eulerian structure, where grains of a given size at a given location in a disc are grouped into super-particles or tracers whose orbits are evolved with an N-body code and whose mutual collisions are individually tracked and treated using a particle-in-a-box prescription designed to handle fragmenting impacts. To cope with the wide range of possible dynamics for same-sized particles at any given location in the disc, and in order not to lose important dynamical information, tracers are sorted and regrouped into dynamical families depending on their orbits. A complex reassignment routine that searches for redundant tracers in each family and reassignes them where they are needed, prevents the number of tracers from diverging. Results: The LIDT-DD code has been successfully tested on simplified cases for which robust results have

  19. Letter detection in very familiar texts.

    Greenberg, S N; Tai, J

    2001-12-01

    In the present study, we investigated whether patterns of letter detection for function and content words in texts are affected by the familiarity of the material being read. In Experiment 1, subjects searched for target letters in sentences that had been rehearsed prior to performing the letter detection on them as well as on unfamiliar sentences. In Experiment 2, subjects searched for target letters in highly familiar verses (e.g., nursery rhymes) and in unfamiliar sentences that were matched to the familiar verses. A disadvantage in letter detection for function as compared with content words consistently found with unfamiliar passages was reduced significantly with the familiar material in both experiments. Specifically, letter detection for content words grew worse in familiar text, but letter detection for function words showed a contrasting modest, though nonsignificant, improvement. The results are consistent with the proposition that in very familiar texts, parafoveal analysis permits the identification of generally less familiar content words. Simultaneously, the normal pattern of weighing the structure and content elements of text changes so that more fixations on function words occur than when one is reading unfamiliar texts.

    Objective  To examine how poor reporting and inadequate methods for key methodological features in randomised controlled trials (RCTs) have changed over the past three decades. Design  Mapping of trials included in Cochrane reviews. Data sources  Data from RCTs included in all Cochrane reviews published between March 2011 and September 2014 reporting an evaluation of the Cochrane risk of bias items: sequence generation, allocation concealment, blinding, and incomplete outcome data. Data extraction  For each RCT, we extracted consensus on risk of bias made by the review authors and identified the primary reference to extract publication year and journal. We matched journal names with Journal Citation Reports to get 2014 impact factors. Main outcomes measures  We considered the proportions of trials rated by review authors at unclear and high risk of bias as surrogates for poor reporting and inadequate methods, respectively. Results  We analysed 20 920 RCTs (from 2001 reviews) published in 3136 journals. The proportion of trials with unclear risk of bias was 48.7% for sequence generation and 57.5% for allocation concealment; the proportion of those with high risk of bias was 4.0% and 7.2%, respectively. For blinding and incomplete outcome data, 30.6% and 24.7% of trials were at unclear risk and 33.1% and 17.1% were at high risk, respectively. Higher journal impact factor was associated with a lower proportion of trials at unclear or high risk of bias. The proportion of trials at unclear risk of bias decreased over time, especially for sequence generation, which fell from 69.1% in 1986-1990 to 31.2% in 2011-14 and for allocation concealment (70.1% to 44.6%). After excluding trials at unclear risk of bias, use of inadequate methods also decreased over time: from 14.8% to 4.6% for sequence generation and from 32.7% to 11.6% for allocation concealment. Conclusions  Poor reporting and inadequate methods have decreased over time, especially for sequence generation

    The objective for this study was to investigate the effects of prior familiarization with takeover requests (TORs) during conditional automated driving on drivers' initial takeover performance and automation trust. System-initiated TORs are one of the biggest concerns for conditional automated driving and have been studied extensively in the past. Most, but not all, of these studies have included training sessions to familiarize participants with TORs. This makes them hard to compare and might obscure first-failure-like effects on takeover performance and automation trust formation. A driving simulator study compared drivers' takeover performance in two takeover situations across four prior familiarization groups (no familiarization, description, experience, description and experience) and automation trust before and after experiencing the system. As hypothesized, prior familiarization with TORs had a more positive effect on takeover performance in the first than in a subsequent takeover situation. In all groups, automation trust increased after participants experienced the system. Participants who were given no prior familiarization with TORs reported highest automation trust both before and after experiencing the system. The current results extend earlier findings suggesting that prior familiarization with TORs during conditional automated driving will be most relevant for takeover performance in the first takeover situation and that it lowers drivers' automation trust. Potential applications of this research include different approaches to familiarize users with automated driving systems, better integration of earlier findings, and sophistication of experimental designs.

    How do infants find the words in the tangle of speech that confronts them? The present study shows that by as early as 6 months of age, infants can already exploit highly familiar words-including, but not limited to, their own names-to segment and recognize adjoining, previously unfamiliar words from fluent speech. The head-turn preference procedure was used to familiarize babies with short passages in which a novel word was preceded by a familiar or a novel name. At test, babies recognized the word that followed the familiar name, but not the word that followed the novel name. This is the youngest age at which infants have been shown capable of segmenting fluent speech. Young infants have a powerful aid available to them for cracking the speech code. Their emerging familiarity with particular words, such as their own and other people's names, can provide initial anchors in the speech stream.

  7. Familiar face + novel face = familiar face? Representational bias in the perception of morphed faces in chimpanzees

    2016-08-01

    Full Text Available Highly social animals possess a well-developed ability to distinguish the faces of familiar from novel conspecifics to induce distinct behaviors for maintaining society. However, the behaviors of animals when they encounter ambiguous faces of familiar yet novel conspecifics, e.g., strangers with faces resembling known individuals, have not been well characterised. Using a morphing technique and preferential-looking paradigm, we address this question via the chimpanzee’s facial–recognition abilities. We presented eight subjects with three types of stimuli: (1 familiar faces, (2 novel faces and (3 intermediate morphed faces that were 50% familiar and 50% novel faces of conspecifics. We found that chimpanzees spent more time looking at novel faces and scanned novel faces more extensively than familiar or intermediate faces. Interestingly, chimpanzees looked at intermediate faces in a manner similar to familiar faces with regards to the fixation duration, fixation count, and saccade length for facial scanning, even though the participant was encountering the intermediate faces for the first time. We excluded the possibility that subjects merely detected and avoided traces of morphing in the intermediate faces. These findings suggest a bias for a feeling-of-familiarity that chimpanzees perceive familiarity with an intermediate face by detecting traces of a known individual, as 50% alternation is sufficient to perceive familiarity.

  8. Familiarity and preference for pitch probability profiles.

    We investigated familiarity and preference judgments of participants toward a novel musical system. We exposed participants to tone sequences generated from a novel pitch probability profile. Afterward, we either asked participants to identify more familiar or we asked participants to identify preferred tone sequences in a two-alternative forced-choice task. The task paired a tone sequence generated from the pitch probability profile they had been exposed to and a tone sequence generated from another pitch probability profile at three levels of distinctiveness. We found that participants identified tone sequences as more familiar if they were generated from the same pitch probability profile which they had been exposed to. However, participants did not prefer these tone sequences. We interpret this relationship between familiarity and preference to be consistent with an inverted U-shaped relationship between knowledge and affect. The fact that participants identified tone sequences as even more familiar if they were generated from the more distinctive (caricatured) version of the pitch probability profile which they had been exposed to suggests that the statistical learning of the pitch probability profile is involved in gaining of musical knowledge.

Las terapias familiares de tipo psicoeducativo mejoran el pronóstico de la enfermedad y además previenen la aparición de otros trastornos en los familiares. Los elementos más importantes de estas intervenciones son la psicoeducación sobre el trastorno, el re-establecimiento de una relación sana entre paciente-familia, el establecimiento de límites, la mejora de la comunicación familiar y el establecimiento de relaciones con la red social extensa, para evitar el aislamiento tanto de la familia como del paciente. Las intervenciones mixtas, individuales y familiares, han demostrado ser muy útiles en el caso de los trastornos de personalidad, en concreto en el Trastorno Límite de Personalidad (TLP.

    Hydrogeological site characterization for deep geological high level and intermediate level long lived radioactive waste repository cover a large time scale needed for safety analysis and calculation. Hydrogeological performance of a site relies also on the effects of geodynamic evolution as tectonic uplift, erosion/sedimentation and climate including glaciation on the groundwater flow and solute and heat transfer. Thermo-Hydro-Mechanical model of multilayered aquifer system of Paris Basin is developed to reproduce the present time flow and the natural tracer (Helium) concentration profiles based on the last 2 Ma of geodynamic evolution. Present time geological conceptual model consist of 27 layers at Paris Basin (Triassic-Tertiary) with refinement at project site scale (29 layers from Triassic to Portlandian). Target layers are the clay host formation of Callovo-Oxfrodian age (160 Ma) and the surrounding aquifer layers of Oxfordian and Dogger. Modelled processes are: groundwater flow, heat and solutes (natural tracers) transport, freezing and thawing of groundwater (expansion and retreat of permafrost), deformation of the multilayered aquifer system induced by differential tectonic uplift and the hydro-mechanical stress effect as caused by erosion of the outcropping layers. Numerical simulation considers a period from 2 Ma BP and up to the present. Transient boundary conditions are governed by geodynamic processes: (i) modification of the geometry of the basin and (ii) temperatures along the topography will change according to a series of 15 identical climate cycles with multiple permafrost (glaciation) periods. Numerical model contains 71 layers and 18 million cells. The solution procedure solves three coupled systems of equations, head, temperature and concentrations, by the use of a finite difference method, and by applying extensive parallel processing. The major modelling results related to the processes of importance for site characterization as hydraulic

    2013-01-01

    In border region studies, the concept of (un)familiarity is applied in empirical studies of consumer culture across borders, illustrating how feelings of unfamiliarity can have an off-putting influence on cross-border interaction (e.g. because of dislike of or lack of attraction to the other side......) at the same time as it can be an incentive for people living at borders to cross them (e.g. to explore the exotic other side). The concepts explanatory scope has, thus, far responded to the normative claim that a borderless Europe encourages and increases mobility. However, in previous studies applying...... the concept of (un)familiarity, an explanatory problem remains concerning people's unarticulated and perhaps deeper reasons for mobility and lack thereof. This leaves a question mark as to why feelings of (un)familiarity occur in the first place as well as the actual degree to which they constitute barriers...

    2001-10-01

    In this study, we examined eyewitness identification involving a person who was slightly familiar to the witness. Although identification of a familiar person has been believed to be more accurate than that of a stranger, we expected that misidentification of a familiar distracter as the target would occur, and in such cases, the witness would be more confidence than when correctly rejecting the familiar person. A total of 102 participants were assigned to one of four conditions where familiarity with the distracter and the visibility of the target's photo were manipulated. First, they rated impressions of several photos in terms of personality traits to increase familiarity of some, then were presented with the target photo in either dark or bright condition. Finally, they were asked to identify the target in a two-photo lineup, where the critical trial included a familiar distracter. Results indicated that 66.7 per cent of subjects who saw the target photo in the dark condition misidentified the distracter as the target. At the same time, confidence for the choice (misidentification) was significantly higher than that of correct rejection. The findings were discussed from the forensic viewpoint.

    Los Alamos National Laboratory (LANL, the Laboratory, or the Lab) conducts familiarization tours for Los Alamos County Fire Department (LAFD) personnel at the Strategic Computing Complex (SCC), TA-03-2327, and the Nonproliferation & International Security Complex (NISC), TA-03-2322. These tours are official LANL business; their purpose is to orient the firefighters to the SCC and the NISC so that they can respond efficiently and quickly to a variety of emergency situations. The tour includes ingress and egress of the buildings, layout and organization of the buildings, evacuation procedures, and areas of concern to emergency responders within these buildings. LAFD firefighters have the training, skills, and abilities to perform these emergency responder tasks; other LANL personnel who have the required clearance level cannot perform these tasks. This handout provides details of the information, along with maps and diagrams, to be presented during the familiarization tours. The report will be distributed to the trainees at the time of the tour. A corresponding checklist will also be used as guidance during the familiarization tours to ensure that all required information is presented to the LAFD personnel.

    Full Text Available El año 2014, marca un hito para la agricultura mundial. En efecto se trata del ano en el cual la FAO ha reconocido públicamente la importancia de la Agricultura familiar a nivel mundial, al igual que ha intentando abrir un debate acerca del re direccionamiento de las políticas agrícolas y sociales con el fin de promover este tipo de agricultura y comprender sus desafíos. Durante el mismo año se publica este libro el cual ya nos revela desde su título, que el debate no debe centrarse en la Agricultura familiar sino en “Las agriculturas familiares” debido a su diversidad y roles fundamentales en el desarrollo agrario. Los diferentes autores que participan en la construcción de esta obra plantean redefinir y comprender a las agriculturas familiares utilizando criterios de diferenciación específicos, de igual manera presentan las contribuciones de esta forma de agricultura en las dinámicas territoriales y elaboran al mismo tiempo reflexiones muy interesantes en torno a los desafíos futuros en materia social y económica en los cuales la agricultura familiar podría jugar en el futuro un rol predominante

  3. Repetition priming affects guessing not familiarity

    2007-08-01

    Full Text Available Abstract Background The claim that recollection and familiarity based memory processes have distinct retrieval mechanisms is based partly on the observation that masked repetition and semantic priming influence estimates of familiarity derived from know responses but have no effect on estimates of recollection derived from remember responses. Close inspection of the experiments on which this claim is based reveal the effect size to be small, potentially the result of a type-2 error, and/or inflated due to participants not having the opportunity to report guesses. This paper re-evaluates these claims by attempting a partial replication of two such Experiments. Methods In Experiment 1 participants made remember, know, and guess responses following primed and unprimed target words. In Experiment 2 participants made sure, unsure, and guess following primed and unprimed target words. Results In Experiment 1 the repetition priming effect occurred only for guess responses and only for unstudied items. In Experiment 2 the priming effect occurred for both unsure and guess responses, but again only for unstudied items. Conclusion The data are consistent with the view that remembering and knowing do not correspond to confidence ratings; and suggest that contrary to earlier findings, recollection and familiarity do not differ in retrieval mechanisms. As such the effects of repetition priming on subjective reports of remembering should not be cited as evidence for the distinction between recollection and familiarity based memory processes.

  5. Facelock: familiarity-based graphical authentication

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Authentication codes such as passwords and PIN numbers are widely used to control access to resources. One major drawback of these codes is that they are difficult to remember. Account holders are often faced with a choice between forgetting a code, which can be inconvenient, or writing it down, which compromises security. In two studies, we test a new knowledge-based authentication method that does not impose memory load on the user. Psychological research on face recognition has revealed an important distinction between familiar and unfamiliar face perception: When a face is familiar to the observer, it can be identified across a wide range of images. However, when the face is unfamiliar, generalisation across images is poor. This contrast can be used as the basis for a personalised ‘facelock’, in which authentication succeeds or fails based on image-invariant recognition of faces that are familiar to the account holder. In Study 1, account holders authenticated easily by detecting familiar targets among other faces (97.5% success rate, even after a one-year delay (86.1% success rate. Zero-acquaintance attackers were reduced to guessing (<1% success rate. Even personal attackers who knew the account holder well were rarely able to authenticate (6.6% success rate. In Study 2, we found that shoulder-surfing attacks by strangers could be defeated by presenting different photos of the same target faces in observed and attacked grids (1.9% success rate. Our findings suggest that the contrast between familiar and unfamiliar face recognition may be useful for developers of graphical authentication systems.

  7. Preferring familiar emotions: As you want (and like) it?

    Ford, Brett Q.; Tamir, Maya

    2014-01-01

    Do people want to feel emotions that are familiar to them? In two studies, participants rated how much they typically felt various emotions (i.e., familiarity of the emotion) and how much they generally wanted to experience these emotions. We found that, in general, people wanted to feel pleasant emotions more than unpleasant emotions. However, for both pleasant and unpleasant emotions, people more (vs. less) familiar with an emotion also wanted to experience it more. Links between the familiarity of an emotion and wanting to experience that emotion were not explained by the concurrent experience of familiar emotions. Also, we show that although familiar emotions were also liked more, liking did not fully account for wanting familiar emotions. Finally, the familiarity of emotions mediated the links between trait affect and the emotions people wanted to feel. We propose that people are motivated to feel familiar emotions, in part, because of their instrumental value. PMID:23962316

    2017-09-01

    Full Text Available ObjectiveFamiliarity is a subjective sensation that contributes to person recognition. This process is described as an emotion-based memory-trace of previous meetings and could be disrupted in schizophrenia. Consequently, familiarity disorders could be involved in the impaired social interactions observed in patients with schizophrenia. Previous studies have primarily focused on famous people recognition. Our aim was to identify underlying features, such as emotional disturbances, that may contribute to familiarity disorders in schizophrenia. We hypothesize that patients with familiarity disorders will exhibit a lack of familiarity that could be detected by a flattened skin conductance response (SCR.MethodThe SCR was recorded to test the hypothesis that emotional reactivity disturbances occur in patients with schizophrenia during the categorization of specific familiar, famous and unknown faces as male or female. Forty-eight subjects were divided into the following 3 matched groups with 16 subjects per group: control subjects, schizophrenic people with familiarity disorder, and schizophrenic people without familiarity disorders.ResultsEmotional arousal is reflected by the skin conductance measures. The control subjects and the patients without familiarity disorders experienced a differential emotional response to the specific familiar faces compared with that to the unknown faces. Nevertheless, overall, the schizophrenic patients without familiarity disorders showed a weaker response across conditions compared with the control subjects. In contrast, the patients with familiarity disorders did not show any significant differences in their emotional response to the faces, regardless of the condition.ConclusionOnly patients with familiarity disorders fail to exhibit a difference in emotional response between familiar and non-familiar faces. These patients likely emotionally process familiar faces similarly to unknown faces. Hence, the lower

  12. Familiarity adds to attractiveness in matters of siskin mate choice.

    2013-12-22

    There is currently considerable controversy in evolutionary ecology revolving around whether social familiarity brings attraction when a female chooses a mate. The topic of familiarity is significant because by avoiding or preferring familiar individuals as mates, the potential for local adaptation may be reduced or favoured. The topic becomes even more interesting if we simultaneously analyse preferences for familiarity and sexual ornaments, because when familiarity influences female mating preferences, this could very significantly affect the strength of sexual selection on male ornamentation. Here, we have used mate-choice experiments in siskins Carduelis spinus to analyse how familiarity and patterns of ornamentation (i.e. the size of wing patches) interact to influence mating success. Our results show that females clearly prefer familiar individuals when choosing between familiar and unfamiliar males with similar-sized wing patches. Furthermore, when females were given the choice between a highly ornamented unfamiliar male and a less ornamented familiar male, half of the females still preferred the socially familiar birds as mates. Our finding suggests that male familiarity may be as important as sexual ornaments in affecting female behaviour in mate choice. Given that the potential for local adaptation may be favoured by preferring familiar individuals as mates, social familiarity as a mate-choice criterion may become a potential area of fruitful research on sympatric speciation processes.

  13. Familiarity and recollection in heuristic decision making.

    Schwikert, Shane R; Curran, Tim

    2014-12-01

    Heuristics involve the ability to utilize memory to make quick judgments by exploiting fundamental cognitive abilities. In the current study we investigated the memory processes that contribute to the recognition heuristic and the fluency heuristic, which are both presumed to capitalize on the byproducts of memory to make quick decisions. In Experiment 1, we used a city-size comparison task while recording event-related potentials (ERPs) to investigate the potential contributions of familiarity and recollection to the 2 heuristics. ERPs were markedly different for recognition heuristic-based decisions and fluency heuristic-based decisions, suggesting a role for familiarity in the recognition heuristic and recollection in the fluency heuristic. In Experiment 2, we coupled the same city-size comparison task with measures of subjective preexperimental memory for each stimulus in the task. Although previous literature suggests the fluency heuristic relies on recognition speed alone, our results suggest differential contributions of recognition speed and recollected knowledge to these decisions, whereas the recognition heuristic relies on familiarity. Based on these results, we created a new theoretical framework that explains decisions attributed to both heuristics based on the underlying memory associated with the choice options.

    Full Text Available Las comunidades indígenas Mayas de la península de Yucatán han practicado la antigua tradición de agricultura familiar, en particular los huertos caseros, para garantizar su seguridad alimentaria. Con el objetivo de mejorar la práctica tradicional considerando paradigmas de la ciencia moderna, por una parte, se colectaron datos para definir la complejidad estructural y diversidad funcional a partir de 20 huertos familiares en cinco comunidades: X - Maben, X - Pichil, X - Yatil, San José II y Melchor Ocampo; y por otra, se organizaron grupos de discusión para dilucidar la estrategia de gestión practicada por las comunidades nativas. Los resultados mostraron que los huertos son manejados principalmente por las mujeres. También mostraron que el propósito principal del crecimiento y mantenimiento de los huertos familiares es garantizar la producción de alimentos nutritivos durante todo el año. Y, por último que los huertos caseros también sirven para propósitos secundarios tales como la provisión de productos y servicios para la medicina tradicional. El estudio sugiere que se debe de promover e invertir en huertos caseros para mejorar las estrategias de desarrollo incluyente en ambientes socio-culturales y biofísicos similares.

La seva finalitat és poder donar resposta a dos qüestions principals: identificar les característiques diferencials de l’EF respecte a l’EnF i comprovar si aquestes característiques diferencials han permès a les EF aguantar millor la crisi econòmica. Disseny/metodologia: S’ha analitzat una mostra de 750 grans i mitjanes empreses de Catalunya (550 familiars i 200 no familiars durant el període 2008-2012. Les dades s’han obtingut a través de la base de dades SABI, i per a la classificació de les empreses en familiars i no familiars s’ha dut a terme una comprovació individual de cadascuna d’elles per evitar habituals errors de classificació. Posteriorment les empreses s’han classificat en funció de la seva dimensió per dotar d’una major robustes els resultats. També s’ha procurat que la distribució d’empreses per sectors fos similar en les diferents categories per evitar que un efecte sectorial pogués tergiversar els resultats de l’estudi. Aportacions i resultats: L’estudi ha permès constatar les hipòtesis establertes sobre el finançament de les empreses familiars i concloure que aquestes presenten una estructura financera diferent a les Empreses no familiars. Les empreses familiars als seus balanços, presenten un major nivell d’autofinançament gràcies a la seva menor distribució de dividends. A més a més, les EF presenten millors resultats en quant a nivells de cobertura i liquiditat, ja que es troben més capitalitzades i presenten uns nivells d’endeutament inferior que les Empreses no familiars.

  9. Development of nonperturbative nonlinear optics models including effects of high order nonlinearities and of free electron plasma: Maxwell-Schrödinger equations coupled with evolution equations for polarization effects, and the SFA-like nonlinear optics model

    Science.gov (United States)

    Lorin, E.; Lytova, M.; Memarian, A.; Bandrauk, A. D.

    2015-03-01

    This paper is dedicated to the exploration of non-conventional nonlinear optics models for intense and short electromagnetic fields propagating in a gas. When an intense field interacts with a gas, usual nonlinear optics models, such as cubic nonlinear Maxwell, wave and Schrödinger equations, derived by perturbation theory may become inaccurate or even irrelevant. As a consequence, and to include in particular the effect of free electrons generated by laser-molecule interaction, several heuristic models, such as UPPE, HOKE models, etc, coupled with Drude-like models [1, 2], were derived. The goal of this paper is to present alternative approaches based on non-heuristic principles. This work is in particular motivated by the on-going debate in the filamentation community, about the effect of high order nonlinearities versus plasma effects due to free electrons, in pulse defocusing occurring in laser filaments [3-9]. The motivation of our work goes beyond filamentation modeling, and is more generally related to the interaction of any external intense and (short) pulse with a gas. In this paper, two different strategies are developed. The first one is based on the derivation of an evolution equation on the polarization, in order to determine the response of the medium (polarization) subject to a short and intense electromagnetic field. Then, we derive a combined semi-heuristic model, based on Lewenstein’s strong field approximation model and the usual perturbative modeling in nonlinear optics. The proposed model allows for inclusion of high order nonlinearities as well as free electron plasma effects.

  14. A familiarity disadvantage for remembering specific images of faces.

    Armann, Regine G M; Jenkins, Rob; Burton, A Mike

    2016-04-01

    Familiar faces are remembered better than unfamiliar faces. Furthermore, it is much easier to match images of familiar than unfamiliar faces. These findings could be accounted for by quantitative differences in the ease with which faces are encoded. However, it has been argued that there are also some qualitative differences in familiar and unfamiliar face processing. Unfamiliar faces are held to rely on superficial, pictorial representations, whereas familiar faces invoke more abstract representations. Here we present 2 studies that show, for 1 task, an advantage for unfamiliar faces. In recognition memory, viewers are better able to reject a new picture, if it depicts an unfamiliar face. This rare advantage for unfamiliar faces supports the notion that familiarity brings about some representational changes, and further emphasizes the idea that theoretical accounts of face processing should incorporate familiarity.

    Product and brand familiarity have an important role in consumer choice behaviour and they have been equated with knowledge and experience Consumers having high and low familiarity utilized brand information (an extrinsic cue) in their evaluations, whereas moderately familiar consumers used...... intrinsic cues (product attributes) in evaluating products. The question of whether familiarity moderates the country-of-origin (COO) effect is a valid one. In this present paper, we attempt to provide additional evidence as to how familiarity with products, brands and countries moderates consumer...... evaluation of brand/country alliances.

    2009-07-01

    The purpose of this study was to determine whether self-reported computer familiarity is related to performance on computerized neurocognitive testing. Participants were 130 healthy adults who self-reported whether their computer use was "some" (n = 65) or "frequent" (n = 65). The two groups were individually matched on age, education, sex, and race. All completed the CNS Vital Signs (Gualtieri & Johnson, 2006b) computerized neurocognitive battery. There were significant differences on 6 of the 23 scores, including scores derived from the Symbol-Digit Coding Test, Stroop Test, and the Shifting Attention Test. The two groups were also significantly different on the Psychomotor Speed (Cohen's d = 0.37), Reaction Time (d = 0.68), Complex Attention (d = 0.40), and Cognitive Flexibility (d = 0.64) domain scores. People with "frequent" computer use performed better than people with "some" computer use on some tests requiring rapid visual scanning and keyboard work.

El objetivo principal de este estudio era analizar el papel de las relaciones paternofiliales y la disciplina familiar en el desarrollo de conductas violentas y prosociales de los adolescentes hacia sus padres. En el estudio participaron 585 hijos/as (48% varones entre 12 y 18 años procedentes de 8 centros escolares de la Comunidad Autónoma del País Vasco. Los resultados indican que las relaciones familiares basadas en el afecto y la comunicación son las que favorecen las conductas prosociales de los hijos, y reducen las conductas violentas de éstos en el hogar. Por el contrario, las estrategias de disciplina parental coercitivas y las estrategias parcialmente coercitivas (supervisión y coste de respuesta se asocian a un mayor nivel de violencia física y psicológica de los hijos adolescentes hacia sus padres. Finalmente, se discuten las implicaciones de estos resultados en relación a la educación parental.

    Full Text Available Abstract Background In eukaryotes, histone H3 lysine 9 (H3K9 methylation is a common mechanism involved in gene silencing and the establishment of heterochromatin. The loci of the major heterochromatic H3K9 methyltransferase Su(var3-9 and the functionally unrelated γ subunit of the translation initiation factor eIF2 are fused in Drosophila melanogaster. Here we examined the phylogenetic distribution of this unusual gene fusion and the molecular evolution of the H3K9 HMTase Su(var3-9. Results We show that the gene fusion had taken place in the ancestral line of winged insects and silverfishs (Dicondylia about 400 million years ago. We cloned Su(var3-9 genes from a collembolan and a spider where both genes ancestrally exist as independent transcription units. In contrast, we found a Su(var3-9-specific exon inside the conserved intron position 81-1 of the eIF2γ gene structure in species of eight different insect orders. Intriguinly, in the pea aphid Acyrthosiphon pisum, we detected only sequence remains of this Su(var3-9 exon in the eIF2γ intron, along with an eIF2γ-independent Su(var3-9 gene. This reveals an evolutionary re-fission of both genes in aphids. Su(var3-9 chromo domains are similar to HP1 chromo domains, which points to a potential binding activity to methylated K9 of histone H3. SET domain comparisons suggest a weaker methyltransferase activity of Su(var3-9 in comparison to other H3K9 HMTases. Astonishingly, 11 of 19 previously described, deleterious amino acid substitutions found in Drosophila Su(var3-9 are seemingly compensable through accompanying substitutions during evolution. Conclusion Examination of the Su(var3-9 evolution revealed strong evidence for the establishment of the Su(var3-9/eIF2γ gene fusion in an ancestor of dicondylic insects and a re-fission of this fusion during the evolution of aphids. Our comparison of 65 selected chromo domains and 93 selected SET domains from Su(var3-9 and related proteins offers

  8. The Influence of Familiarity on Affective Responses to Natural Scenes

    Science.gov (United States)

    Sanabria Z., Jorge C.; Cho, Youngil; Yamanaka, Toshimasa

    This kansei study explored how familiarity with image-word combinations influences affective states. Stimuli were obtained from Japanese print advertisements (ads), and consisted of images (e.g., natural-scene backgrounds) and their corresponding headlines (advertising copy). Initially, a group of subjects evaluated their level of familiarity with images and headlines independently, and stimuli were filtered based on the results. In the main experiment, a different group of subjects rated their pleasure and arousal to, and familiarity with, image-headline combinations. The Self-Assessment Manikin (SAM) scale was used to evaluate pleasure and arousal, and a bipolar scale was used to evaluate familiarity. The results showed a high correlation between familiarity and pleasure, but low correlation between familiarity and arousal. The characteristics of the stimuli, and their effect on the variables of pleasure, arousal and familiarity, were explored through ANOVA. It is suggested that, in the case of natural-scene ads, familiarity with image-headline combinations may increase the pleasure response to the ads, and that certain components in the images (e.g., water) may increase arousal levels.

    Rhythmic auditory stimulation (RAS) is a gait rehabilitation method in which patients synchronize footsteps to a metronome or musical beats. Although RAS with music can ameliorate gait abnormalities, outcomes vary, possibly because music properties, such as groove or familiarity, differ across interventions. To optimize future interventions, we assessed how initially familiar and unfamiliar low-groove and high-groove music affected synchronization accuracy and gait in healthy individuals. We also experimentally increased music familiarity using repeated exposure to initially unfamiliar songs. Overall, familiar music elicited faster stride velocity and less variable strides, as well as better synchronization performance (matching of step tempo to beat tempo). High-groove music, as reported previously, led to faster stride velocity than low-groove music. We propose two mechanisms for familiarity's effects. First, familiarity with the beat structure reduces cognitive demands of synchronizing, leading to better synchronization performance and faster, less variable gait. Second, familiarity might have elicited faster gait by increasing enjoyment of the music, as enjoyment was higher after repeated exposure to initially low-enjoyment songs. Future studies are necessary to dissociate the contribution of these mechanisms to the observed RAS effects of familiar music on gait. © 2015 New York Academy of Sciences.

    Full Text Available Se debate el punto de vista que identifica la familia extensa con la tradición y la familia nuclear con el moderno modelo industrial de vida familiar. También se analiza la actual opinión dominante que afirma que la familia ha perdido el papel preponderante social y económico en la sociedad occidental. Se estudian los modelos cambiantes de familia en el Reino Unido, Francia y, especialmente, España. Los aspectos más tratados son los siguientes : la aceptación de los nuevos tipos de relaciones entre los jóvenes, opinión sobre la cohabitación, la imagen del matrimonio como institución, la postura ante el divorcio, el grado de rigidez ante la infidelidad matrimonial, la actitud ante la sexualidad y el grado de deseo de diferenciación de roles entre los sexos. Los datos utilizados están extraídos del banco de datos del Centro de Investigaciones Socilógicas. Como conclusión, se puede decir que en España se siguen las mismas tendencias que en otros países desarrollados : un descenso del valor del matrimonio como institución y un incremento de las relaciones informales.

    Full Text Available Aim of the study: To analyze PsA patients with and without a familiar distribution for Ps and PsA, in order to better evaluate the genetic data, to verify the existence of different expression of the disease and finally to define the susceptibility to treatment in these patients. Materials and methods: 230 PsA patients were selected for familiar or sporadic distribution of the disease and were evaluated for the main clinical, demographic, radiological and laboratory features, as well as for the ongoing treatments. In each patient HLA class I (A,B,C and II (DRB1, DQB1 antigens were typed with PCR-SSP method while MICA-A exon 5 microsatellite typing was performed by heteroduplex analysis in 122 subjects. Results: A familiar distribution for Ps and PsA was found in 68 patients (29.6% although only two patients had familiarity for PsA. In the familiar PsA group the male prevalence was significantly higher respect to the sporadic one (p<0.001 and the more frequently involved relative was the father (28%. Mean age (p<0.006 and age at onset of Ps (p<0.004 and PsA (p<0.014 were significantly lower in familiar respect to sporadic PsA. Between the two groups no difference was found concerning the articular involvement, the radiological findings, the disease activity (including n° of painful/swollen joints, the inflammatory laboratory parameters (including ESR and CRP and genetic aspects, incuding the frequencies of MICA-A alleles that were analysed in 30 patients with the familiar form and in 92 with the sporadic one. In the follow-up the therapeutic response to any evaluated treatment adopted for PsA did not show any significant difference in the two groups. All these results were confirmed even when the patients in the two groups were matchable for sex, age and disease duration. Conclusion: Our results confirm that familiar PsA is characterized by an early onset of the disease and by a male and fatherly predominance respect to the sporadic form

    2010-07-09

    Functional magnetic resonance imaging (fMRI) studies have shown that repetition priming of visual objects is typically accompanied by a reduction in activity for repeated compared to new stimuli (repetition suppression). However, the spatial distribution and direction (suppression vs. enhancement) of neural repetition effects can depend on the pre-experimental familiarity of stimuli. The first goal of this study was to further probe the link between repetition priming and repetition suppression/enhancement for visual objects and how this link is affected by stimulus familiarity. A second goal was to examine whether priming of familiar and unfamiliar objects following a single stimulus repetition is supported by the same processes as priming following multiple repetitions within the same task. In this endeavor, we examined both between and within-subject correlations between priming and fMRI repetition effects for familiar and globally unfamiliar visual objects during the first and third repetitions of the stimuli. We included reaction time of individual trials as a linear regressor to identify brain regions whose repetition effects varied with response facilitation on a trial-by-trial basis. The results showed that repetition suppression in bilateral fusiform gyrus, was selectively correlated with priming of familiar objects that had been repeated once, likely reflecting facilitated perceptual processing or the sharpening of perceptual representations. Priming during the third repetition was correlated with repetition suppression in prefrontal and parietal areas for both familiar and unfamiliar stimuli, possibly reflecting a shift from top-down controlled to more automatic processing that occurs for both item types.

It is still unclear whether the discrepancy between memorized and actual colors of objects is dependent on the familiarity of the objects. Here, we conducted two experiments in order to examine the relationship between the degree of a subject's familiarity with objects and the degree of the memory color effect by using logographs of food and beverage companies.In Experiment 1, we measured the memory color effects of logos which varied in terms of their familiarity (high, middle, or low. Results demonstrate that the memory color effect occurs only in the high-familiarity condition, but not in the middle- and low-familiarity conditions. Furthermore, there is a positive correlation between the memory color effect and the actual number of domestic stores of the brand. In Experiment 2, we assessed the semantic association between logos and food/beverage names by using a semantic priming task to elucidate whether the memory color effect of logos relates to consumer brand cognition, and found that the semantic associations between logos and food/beverage names in the high-familiarity brands were stronger than those in the low-familiarity brands only when the logos were colored correctly, but not when they were appropriately or inappropriately colored, or achromatic.The current results provide behavioral evidence of the relationship between the familiarity of objects and the memory color effect and suggest that the memory color effect increases with the familiarity of objects, albeit not constantly.

    An Oxygen Evolution Reaction (OER) catalyst includes a metal oxide that includes oxygen, cerium, and one or more second metals. In some instances, the cerium is 10 to 80 molar % of the metals in the metal oxide and/or the catalyst includes two or more second metals. The OER catalyst can be included in or on an electrode. The electrode can be arranged in an oxygen evolution system such that the Oxygen Evolution Reaction occurs at the electrode.

    Public level of familiarity with nanotechnology partly determines their acceptance or rejection of the technology. This study examines the differential influence of public attention to science news in the media and reflective integration on perceived familiarity with nanotechnology among people in the higher and lower socioeconomic status (SES) groups in Singapore. Significant three-way interactions among education, science news attention, and reflective integration variables were found. Attention to television science news narrowed the level of perceived familiarity with nanotechnology between the higher and lower SES groups for those who engaged in high elaborative processing. Science newspaper attention, on the other hand, widened the familiarity gap between the higher and lower SES groups among those who engaged in high elaborative processing. Two-way interaction among education and elaborative processing were found—elaborative processing closed the familiarity gap between higher and lower SES groups. Theoretical and practical implications were discussed

  2. Predicting Intentions of a Familiar Significant Other Beyond the Mirror Neuron System

    Full Text Available Inferring intentions of others is one of the most intriguing issues in interpersonal interaction. Theories of embodied cognition and simulation suggest that this mechanism takes place through a direct and automatic matching process that occurs between an observed action and past actions. This process occurs via the reactivation of past self-related sensorimotor experiences within the inferior frontoparietal network (including the mirror neuron system, MNS. The working model is that the anticipatory representations of others' behaviors require internal predictive models of actions formed from pre-established, shared representations between the observer and the actor. This model suggests that observers should be better at predicting intentions performed by a familiar actor, rather than a stranger. However, little is known about the modulations of the intention brain network as a function of the familiarity between the observer and the actor. Here, we combined functional magnetic resonance imaging (fMRI with a behavioral intention inference task, in which participants were asked to predict intentions from three types of actors: A familiar actor (their significant other, themselves (another familiar actor, and a non-familiar actor (a stranger. Our results showed that the participants were better at inferring intentions performed by familiar actors than non-familiar actors and that this better performance was associated with greater activation within and beyond the inferior frontoparietal network i.e., in brain areas related to familiarity (e.g., precuneus. In addition, and in line with Hebbian principles of neural modulations, the more the participants reported being cognitively close to their partner, the less the brain areas associated with action self-other comparison (e.g., inferior parietal lobule, attention (e.g., superior parietal lobule, recollection (hippocampus, and pair bond (ventral tegmental area, VTA were recruited, suggesting that the

    Long-term memory (LTM) can influence many aspects of short-term memory (STM), including increased STM span. However, it is unclear whether LTM enhances the quantitative or qualitative aspect of STM. That is, do we retain a larger number of representations or more precise representations in STM for familiar stimuli than unfamiliar stimuli? This study took advantage of participants' prior rich multimedia experience with Pokémon, without investing on laboratory training to examine how prior LTM influenced visual STM. In a Pokémon visual STM change detection task, participants remembered more first-generation Pokémon characters that they were more familiar with than recent-generation Pokémon characters that they were less familiar with. No significant difference in memory quality was found when quantitative and qualitative effects of LTM were isolated using receiver operating characteristic (ROC) analyses. Critically, these effects were absent in participants who were unfamiliar with first-generation Pokémon. Furthermore, several alternative interpretations were ruled out, including general video-gaming experience, subjective Pokémon preference, and verbal encoding. Together, these results demonstrated a strong link between prior stimulus familiarity in LTM and visual STM storage capacity.

    Human immunodeficiency virus (HIV) exemplifies the principles of Darwinian evolution with a telescoped chronology. Because of its high mutation rate and remarkably high rates of replication, evolution can be appreciated over periods of days in contrast to the durations conceived of by Darwin. Certain selective pressures that drive the evolution of HIV include chemotherapy, anatomic compartmentalization and the immune response. Examples of these selective forces on HIV evolution are described. Images Fig. 5 PMID:17060974

    Full Text Available Evaluating the familiarity of faces is critical for social animals as it is the basis of individual recognition. In the present study, we examined how face familiarity is reflected in neural activities in our closest living relative, the chimpanzee. Skin-surface event-related brain potentials (ERPs were measured while a fully awake chimpanzee observed photographs of familiar and unfamiliar chimpanzee faces (Experiment 1 and human faces (Experiment 2. The ERPs evoked by chimpanzee faces differentiated unfamiliar individuals from familiar ones around midline areas centered on vertex sites at approximately 200 ms after the stimulus onset. In addition, the ERP response to the image of the subject’s own face did not significantly diverge from those evoked by familiar chimpanzees, suggesting that the subject’s brain at a minimum remembered the image of her own face. The ERPs evoked by human faces were not influenced by the familiarity of target individuals. These results indicate that chimpanzee neural representations are more sensitive to the familiarity of conspecific than allospecific faces.

    This paper includes a detailed description of a familiarization protocol, which is used as an integral component of a larger research protocol to collect electroencephalography (EEG) data and Event-Related Potentials (ERPs). At present, the systems available for the collection of high-quality EEG/ERP data make significant demands on children with developmental disabilities, such as those with an Autism Spectrum Disorder (ASD). Children with ASD may have difficulty adapting to novel situations, tolerating uncomfortable sensory stimuli, and sitting quietly. This familiarization protocol uses Evidence-Based Practices (EBPs) to increase research participants' knowledge and understanding of the specific activities and steps of the research protocol. The tools in this familiarization protocol are a social narrative, a visual schedule, the Premack principle, role-playing, and modeling. The goal of this familiarization protocol is to increase understanding and agency and to potentially reduce anxiety for child participants, resulting in a greater likelihood of the successful completion of the research protocol for the collection of EEG/ERP data.

    Humans have a remarkable skill for voice-identity recognition: most of us can remember many voices that surround us as 'unique'. In this review, we explore the computational and neural mechanisms which may support our ability to represent and recognise a unique voice-identity. We examine the functional architecture of voice-sensitive regions in the superior temporal gyrus/sulcus, and bring together findings on how these regions may interact with each other, and additional face-sensitive regions, to support voice-identity processing. We also contrast findings from studies on neurotypicals and clinical populations which have examined the processing of familiar and unfamiliar voices. Taken together, the findings suggest that representations of familiar and unfamiliar voices might dissociate in the human brain. Such an observation does not fit well with current models for voice-identity processing, which by-and-large assume a common sequential analysis of the incoming voice signal, regardless of voice familiarity. We provide a revised audio-visual integrative model of voice-identity processing which brings together traditional and prototype models of identity processing. This revised model includes a mechanism of how voice-identity representations are established and provides a novel framework for understanding and examining the potential differences in familiar and unfamiliar voice processing in the human brain.

    The stress response has been well documented in past music therapy literature. However, hypometabolism, or the relaxation response, has received much less attention. Music therapists have long utilized various music-assisted relaxation techniques with both live and recorded music to elicit such a response. The ongoing proliferations of relaxation music through commercial media and the dire lack of evidence to support such claims warrant attention from healthcare professionals and music therapists. The purpose of these 3 studies was to investigate the correlational relationships between 12 psychophysical properties of music, preference, familiarity, and degree of perceived relaxation in music. Fourteen music therapists recommended and analyzed 30 selections of relaxation music. A group of 80 healthy adults then rated their familiarity, preference, and degree of perceived relaxation in the music. The analysis provided a detailed description of the intrinsic properties in music that were perceived to be relaxing by listeners. These properties included tempo, mode, harmonic, rhythmic, instrumental, and melodic complexities, timbre, vocalization/lyrics, pitch range, dynamic variations, and contour. In addition, music preference was highly correlated with listeners' perception of relaxation in music for both music therapists and healthy adults. The correlation between familiarity and degree of relaxation reached significance in the healthy adult group. Results from this study provided an in-depth operational definition of the intrinsic parameters in relaxation music and also highlighted the importance of preference and familiarity in eliciting the relaxation response.

    Recognition of the identity of familiar faces in conditions with poor visibility or over large changes in head angle, lighting and partial occlusion is far more accurate than recognition of unfamiliar faces in similar conditions. Here we used a visual search paradigm to test if one class of social cues transmitted by faces—direction of another's attention as conveyed by gaze direction and head orientation—is perceived more rapidly in personally familiar faces than in unfamiliar faces. We found a strong effect of familiarity on the detection of these social cues, suggesting that the times to process these signals in familiar faces are markedly faster than the corresponding processing times for unfamiliar faces. In the light of these new data, hypotheses on the organization of the visual system for processing faces are formulated and discussed. PMID:25228873

    Familiarity participates in the pathogenesis of hypertension, although only recently, whole genome studies have proposed regions of the human genome possibly involved in the transmission of the hypertensive phenotype. Although studies have mainly focused on autosome, hitherto the influence of sex on familial transmission of hypertension has not been considered. We analysed the database of the Campania Salute Network of Hypertension center of the Federico II University Hospital of Naples (Italy), using dichotomous variables for paternal and maternal familiarity and gender (male and female) of 12 504 hypertensive patients (6868 males and 5636 females) and 6352 controls (3484 males and 2868 females), totaling 18 856 subjects. In the hypertensive group, familiarity was present in 75% of cases with odds of 3.77 and in only 26% of the normotensives with odds of 0.94. The odds ratio (OR) indicated that familiarity increases the risk of developing hypertension by 2.91 (95% confidence interval (CI)=2.67–3.17, P<0.001) times. Additionally, maternal familiarity was 37% (OR=3.01, 95% CI=2.66–3.41, P<0.001), paternal familiarity was 21% (OR=2.31, 95% CI=2.01–2.68, P<0.001) and the double familiarity was 17% (OR=3.45, 95% CI=2.87–4.01, P<0.001), thus suggesting a plausible association between maternal familiarity and development of hypertension; this finding was observed both in male and in female patients, although the phenomenon was larger in males. Given the dominance of maternal transmission in males, by genome-wide analysis of the X chromosome, we found two regions that were differently distributed in male hypertensives with maternal hypertension. Our data highlight the importance of genetic variants in the X chromosome to the maternal transmission of the hypertensive phenotype. PMID:26911533

El objetivo de esta investigación fue valorar la relación entre el funcionamiento familiar percibido por estudiantes españoles de educación secundaria postobligatoria y su práctica de ocio digital. La muestra ascendió a 1.764 estudiantes. El ocio digital se midió a partir de una pregunta abierta en la que debían señalar las tres actividades de ocio más importantes, y el funcionamiento familiar se valoró mediante la versión española del FACES IV (Escala de cohesión y adaptación familiar. Se realizó un análisis descriptivo sobre las actividades de ocio digital de los jóvenes, se determinó el coeficiente del funcionamiento familiar de cada sujeto y mediante análisis de varianza (ANOVA de un factor se valoró la relación entre el funcionamiento familiar percibido por los estudiantes y las actividades de ocio digital practicadas por los mismos. Los jóvenes otorgan importancia a las actividades digitales de ocio, destacando la participación en redes sociales, jugar a videojuegos y navegar por Internet. La cohesión, la flexibilidad y el funcionamiento familiar gozan de mejor salud cuando los hijos no apuntan actividades digitales entre sus prácticas preferentes de ocio. Los resultados sugieren nuevas investigaciones que comprueben si esta asociación negativa entre funcionamiento familiar y ocio digital es causal o se debe a otros factores.

    Music perception involves complex brain functions. The relationship between music and brain such as cortical entrainment to periodic tune, periodic beat, and music have been well investigated. It has also been reported that the cerebral cortex responded more strongly to the periodic rhythm of unfamiliar music than to that of familiar music. However, previous works mainly used simple and artificial auditory stimuli like pure tone or beep. It is still unclear how the brain response is influenced by the familiarity of music. To address this issue, we analyzed electroencelphalogram (EEG) to investigate the relationship between cortical response and familiarity of music using melodies produced by piano sounds as simple natural stimuli. The cross-correlation function averaged across trials, channels, and participants showed two pronounced peaks at time lags around 70 and 140 ms. At the two peaks the magnitude of the cross-correlation values were significantly larger when listening to unfamiliar and scrambled music compared to those when listening to familiar music. Our findings suggest that the response to unfamiliar music is stronger than that to familiar music. One potential application of our findings would be the discrimination of listeners' familiarity with music, which provides an important tool for assessment of brain activity.

    A slide-tape audiovisual program was developed by a university-based drug information center for the purpose of familiarizing the nursing staff with our institution's formulary. The formulary contains useful information on medications stocked by our pharmacy, including costs, dosage forms, policies and procedures governing the pharmacy department, and many useful tables and figures. It was felt that the nursing staff was not aware of these components and thus, was not optimally utilizing the formulary. Nurses taking a test after the slide-tape presentation scored higher on the average than nurses from similar nursing stations who had not seen the presentation. These results, as well as the positive subjective responses from the individual nurses regarding the presentation, indicate that the slide-tape format is an effective means of acquainting the nursing staff with the hospital formulary. It is anticipated that this new awareness of the formulary will result in its more efficient use and further promote the pharmacy department as an information provider.

  5. The Neuropsychology of Familiar Person Recognition from Face and Voice

    Full Text Available Prosopagnosia has been considered for a long period of time as the most important and almost exclusive disorder in the recognition of familiar people. In recent years, however, this conviction has been undermined by the description of patients showing a concomitant defect in the recognition of familiar faces and voices as a consequence of lesions encroaching upon the right anterior temporal lobe (ATL. These new data have obliged researchers to reconsider on one hand the construct of ‘associative prosopagnosia’ and on the other hand current models of people recognition. A systematic review of the patterns of familiar people recognition disorders observed in patients with right and left ATL lesions has shown that in patients with right ATL lesions face familiarity feelings and the retrieval of person-specific semantic information from faces are selectively affected, whereas in patients with left ATL lesions the defect selectively concerns famous people naming. Furthermore, some patients with right ATL lesions and intact face familiarity feelings show a defect in the retrieval of person-specific semantic knowledge greater from face than from name. These data are at variance with current models assuming: (a that familiarity feelings are generated at the level of person identity nodes (PINs where information processed by various sensory modalities converge, and (b that PINs provide a modality-free gateway to a single semantic system, where information about people is stored in an amodal format. They suggest, on the contrary: (a that familiarity feelings are generated at the level of modality-specific recognition units; (b that face and voice recognition units are represented more in the right than in the left ATLs; (c that in the right ATL are mainly stored person-specific information based on a convergence of perceptual information, whereas in the left ATLs are represented verbally-mediated person-specific information.

  7. ¿"Desintegración familiar" o "Transición familiar"? Perspectivas sobre el cambio familiar en Guanacaste, Costa Rica.

    2011-08-01

    Full Text Available Como en otros países de América Latina y del Caribe, sin mencionar el resto del mundo, la estructura de vida familiar en Costa Rica ha cambiado en décadas recientes. El matrimonio ha decaído, el divorcio y la separación aumentan, se incrementan los nacimientos fuera del matrimonio y en un número creciente de hogares las mujeres son jefas de hogar. Tanto a nivel nacional como internacional estas tendencias han sido consideradas como indicadores de una “desintegración familiar”. Esto a su vez con frecuencia ha causado preocupación, especialmente en relación a posibles amenazas al bienestar y desarrollo de los niños. Si bien estas preocupaciones sobre la ruptura familiar han sido expuestas en los medios de comunicación, en informes oficiales y en declaraciones de instituciones religiosas, poco se conoce sobre las vivencias de las personas sobre estos cambios. ¿ Hasta qué punto las personas perciben los cambios en la organización familiar y si es así, a qué los atribuyen? ¿Se podría pensar que los cambios identificados están llevando al “colapso familiar” ?, y ¿Hasta qué punto son tales interpretaciones compartidas por diferentes grupos en términos de género, edad y situación socioeconómica?Este artículo plantea algunas respuestas a estas inquietudes con base en entrevistas individuales y grupos focales de discusión. Se trabajó con 176 hombres y mujeres de bajo y mediano ingreso, de diferentes edades en la provincia de Guanacaste, Costa Rica. Una de las principales conclusiones es que si bien algunos estilos en la vida familiar se perciben como posibilitadoras de condiciones más flexibles y equitativas, otras se consideran como debilitadoras de la unidad familiar. Además, las preocupaciones sobre la “desintegración familiar” son particularmente comunes en los hombres adultos, a pesar de que ellos han estado históricamente menos comprometidos en la vida familiar que las mujeres.

Se destaca el rol que desempeñan en materia de generación de empleo y riqueza. También se analizan sus sistemas de gobierno corporativo, los cuales desembocan en la temática de continuidad generacional. La continuidad es entendida como una de las principales dificultades de estas organizaciones, debido a que sus directivos y/o propietarios no logran separar el papel del núcleo familiar y las decisiones organizacionales de las compañías. En este sentido, las estrategias de internacionalización y profesionalización representan el camino para garantizar la permanencia de las empresas familiares.

  13. Familiarity affects collective motion in shoals of guppies (Poecilia reticulata).

    Davis, Scarlet; Lukeman, Ryan; Schaerf, Timothy M; Ward, Ashley J W

    2017-09-01

    The coordinated and synchronized movement of animals in groups often referred to as collective motion emerges through the interactions between individual animals within the group. Factors which affect these interactions have the potential to shape collective movement. One such factor is familiarity, or the tendency to bias behaviour towards individuals as a result of social recognition. We examined the effect of familiarity on the expression of collective motion in small shoals of female guppies ( Poecilia reticulata ). Groups comprising familiar individuals were more strongly polarized than groups of unfamiliar individuals, particularly when in novel surroundings. The ability to form more strongly polarized shoals potentially promotes information transfer and enhances the anti-predator benefits of grouping.

  14. Roles of familiarity and novelty in visual preference judgments are segregated across object categories.

    2010-08-17

    Understanding preference decision making is a challenging problem because the underlying process is often implicit and dependent on context, including past experience. There is evidence for both familiarity and novelty as critical factors for preference in adults and infants. To resolve this puzzling contradiction, we examined the cumulative effects of visual exposure in different object categories, including faces, natural scenes, and geometric figures, in a two-alternative preference task. The results show a clear segregation of preference across object categories, with familiarity preference dominant in faces and novelty preference dominant in natural scenes. No strong bias was observed in geometric figures. The effects were replicated even when images were converted to line drawings, inverted, or presented only briefly, and also when spatial frequency and contour distribution were controlled. The effects of exposure were reset by a blank of 1 wk or 3 wk. Thus, the category-specific segregation of familiarity and novelty preferences is based on quick visual categorization and cannot be caused by the difference in low-level visual features between object categories. Instead, it could be due either to different biological significances/attractiveness criteria across these categories, or to some other factors, such as differences in within-category variance and adaptive tuning of the perceptual system.

    2006-01-01

    In the amnesia literature, disagreement exists over whether anterograde amnesia involves recollective-based recognition processes and/or familiarity-based ones depending on whether the anatomical damage is restricted to the hippocampus or also involves adjacent areas, particularly the entorhinal and perirhinal cortices. So far, few patients with well documented anatomical lesions and detailed assessment of recollective and recognition performance have been described. We report a comprehensive neuroanatomical assessment and detailed investigation of the anterograde memory functions of a previously described severe amnesic patient (VC). The results of four previously published neuroradiological investigations (resting PET, qualitative MRIs, volumetric MRI and functional MRI) together with the results of two new investigations (voxel-based morphometry and magnetic resonance spectroscopy) are presented. The consistent finding across these different qualitative and quantitative examinations of VC's brain has shown that there is primarily structural and functional abnormality located selectively in the hippocampus bilaterally. Marked impairments in both verbal and non-verbal recall and recognition standardized memory tests were documented in the context of VC's intact cognitive profile and normal semantic memory. The results of five new experimental recognition memory tests tapping recollection and familiarity using verbal, topographical (buildings and landscapes) and unknown human faces memoranda revealed striking differential effects according to the type of stimuli used. A receiver operating characteristic analysis revealed that VC's recollective- and familiarity-based recognition processes were well preserved for unknown human faces. In contrast, recollective-based recognition for verbal and topographical material was at floor. Familiarity-based recognition was also impaired, significantly below controls for verbal and buildings memoranda and quite weak, although not

    Existing long-term memory (LTM) can boost the number of retained representations over a short delay in visual short-term memory (VSTM). However, it is unclear whether and how prior LTM affects the initial process of transforming fragile sensory inputs into durable VSTM representations (i.e., VSTM consolidation). The consolidation speed hypothesis predicts faster consolidation for familiar relative to unfamiliar stimuli. Alternatively, the perceptual boost hypothesis predicts that the advantage in perceptual processing of familiar stimuli should add a constant boost for familiar stimuli during VSTM consolidation. To test these competing hypotheses, the present study examined how the large variance in participants' prior multimedia experience with Pokémon affected VSTM for Pokémon. In Experiment 1, the amount of time allowed for VSTM consolidation was manipulated by presenting consolidation masks at different intervals after the onset of to-be-remembered Pokémon characters. First-generation Pokémon characters that participants were more familiar with were consolidated faster into VSTM as compared with recent-generation Pokémon characters that participants were less familiar with. These effects were absent in participants who were unfamiliar with both generations of Pokémon. Although familiarity also increased the number of retained Pokémon characters when consolidation was uninterrupted but still incomplete due to insufficient encoding time in Experiment 1, this capacity effect was absent in Experiment 2 when consolidation was allowed to complete with sufficient encoding time. Together, these results support the consolidation speed hypothesis over the perceptual boost hypothesis and highlight the importance of assessing experimental effects on both processing and representation aspects of VSTM.

  7. Dogs' comprehension of referential emotional expressions: familiar people and familiar emotions are easier.

    Merola, I; Prato-Previde, E; Lazzaroni, M; Marshall-Pescini, S

    2014-03-01

    Dogs have been shown to discriminate between human facial expressions, and they seem to use human emotional communication to regulate their behaviour towards an external object/situation. However, it is still not clear (1) whether they just respond to the emotional message received with a corresponding increase/decrease in their level of activation or whether they perceive that the emotional message refers to a specific object, (2) which emotional message they use to modify their behaviour (i.e. whether they are following the positive message or avoiding the negative one) and (3) whether their familiarity with the informant has an effect on the dogs' behaviour. To address these issues, five groups of dogs were tested in two experiments. The first group observed the owner delivering two different emotional messages (happiness and fear) towards two identical objects hidden behind barriers, and the second group observed the owner delivering the same emotional messages but with no-objects present in the room. The third and the fourth groups observed the owner delivering a happy versus a neutral, and a negative versus a neutral emotional message towards the hidden objects. Finally, the fifth group observed a stranger acting like the owner of the first group. When the owner was acting as the informant, dogs seemed to be capable of distinguishing between a fearful and happy emotional expression and preferentially chose to investigate a box eliciting an expression of happiness rather than of fear or neutrality. Dogs, however, seemed to have greater difficulty in distinguishing between the fearful and neutral emotional messages delivered by the owner and between the happy and fearful expressions delivered by the stranger. Results suggest that dogs have learned to associate their owners' positive emotional messages to positive outcomes, and hence use their communicative messages to guide their actions. However, negative emotional messages and those delivered by strangers are

    2011-10-01

    Full Text Available Studies employing event-related potentials (ERPs have shown that when participants are monitoring for a novel target face, the presentation of their own face elicits an enhanced negative brain potential in posterior channels approximately 250 ms after stimulus onset. Here, we investigate whether the own-face N250 effect generalizes to other highly familiar objects, specifically, images of the participant’s own dog and own car. In our experiments, participants were asked to monitor for a pre-experimentally unfamiliar target face (Joe, a target dog (Experiment 1: Joe’s Dog or a target car (Experiment 2: Joe’s Car. The target face and object stimuli were presented with non-target foils that included novel face and object stimuli, the participant’s own face, their own dog (Experiment 1 and their own car (Experiment 2. The consistent findings across the two experiments were the following: 1 the N250 potential differentiated the target faces and objects from the non-target face and object foils and 2 despite being non-targets, the own face and own objects produced an N250 response that was equal in magnitude to the target faces and objects by the end of the experiment. Thus, as indicated by its response to personally familiar and recently familiarized faces and objects, the N250 component is a sensitive index of individuated representations in visual memory.

    Two experiments assessed effects of color preference and brand-logo familiarity on recall performance. Exp. 1 explored the color preferences, using a forced-choice technique, of 189 women and 63 men, Taiwanese college students ages 18 to 20 years (M = 19.4, SD = 1.5). The sequence of the three most preferred colors was white, light blue, and black and of the three least preferred colors was light orange, dark violet, and dark brown. Exp. 2 investigated the effects of color preference based on the results of Exp. 1 and brand-logo familiarity on recall. A total of 27 women and 21 men, Taiwanese college students ages 18 to 20 years (M = 19.2, SD = 1.2) participated. They memorized a list of 24 logos (four logos shown in six colors) and then performed sequential recall. Analyses showed color preference significantly affected recall accuracy. Accuracy for high color preference was significantly greater than that for low preferences. Results showed no significant effects of brand-logo familiarity or sex on accuracy. In addition, the interactive effect of color preference and brand-logo familiarity on accuracy was significant. These results have implications for the design of brand logos to create and sustain memory of brand images.

    Directory of Open Access Journals (Sweden)

    Martin Wiesmann

    2008-05-01

    Full Text Available We used event-related fMRI to investigate whether recollection- and familiarity-based memory judgments are modulated by the degree of visual similarity between old and new art paintings. Subjects performed a flower detection task, followed by a Remember/Know/New surprise memory test. The old paintings were randomly presented with new paintings, which were either visually similar or visually different. Consistent with our prediction, subjects were significantly faster and more accurate to reject new, visually different paintings than new, visually similar ones. The proportion of false alarms, namely remember and know responses to new paintings, was significantly reduced with decreased visual similarity. The retrieval task evoked activation in multiple visual, parietal and prefrontal regions, within which remember judgments elicited stronger activation than know judgments. New, visually different paintings evoked weaker activation than new, visually similar items in the intraparietal sulcus. Contrasting recollection with familiarity revealed activation predominantly within the precuneus, where the BOLD response elicited by recollection peaked significantly earlier than the BOLD response evoked by familiarity judgments. These findings suggest that successful memory retrieval of pictures is mediated by activation in a distributed cortical network, where memory strength is manifested by differential hemodynamic profiles. Recollection- and familiarity-based memory decisions may therefore reflect strong memories and weak memories, respectively.

    In language acquisition research, the prevailing position is that listeners exploit statistical cues, in particular transitional probabilities between syllables, to discover words of a language. However, other cues are also involved in word discovery. Assessing the weight learners give to these different cues leads to a better understanding of the processes underlying speech segmentation. The present study evaluated whether adult learners preferentially used known units or statistical cues for segmenting continuous speech. Before the exposure phase, participants were familiarized with part-words of a three-word artificial language. This design allowed the dissociation of the influence of statistical cues and familiar units, with statistical cues favoring word segmentation and familiar units favoring (nonoptimal) part-word segmentation. In Experiment 1, performance in a two-alternative forced choice (2AFC) task between words and part-words revealed part-word segmentation (even though part-words were less cohesive in terms of transitional probabilities and less frequent than words). By contrast, an unfamiliarized group exhibited word segmentation, as usually observed in standard conditions. Experiment 2 used a syllable-detection task to remove the likely contamination of performance by memory and strategy effects in the 2AFC task. Overall, the results suggest that familiar units overrode statistical cues, ultimately questioning the need for computation mechanisms of transitional probabilities (TPs) in natural language speech segmentation.

    Use of health services is usually associated with a variety of factors, including the socioeconomic characteristics of the users, their familiarity with the usefulness of the services provided, and the acceptability and accessibility of those services. To study the factors associated with women's familiarity with the Pap test, a population-based study was carried out in Mexico City and two rural areas in the state of Oaxaca by means of household interviews. The sample consisted of 4208 women 15 to 49 years of age. Univariate, bivariate, and multivariate analyses were done using unconditional logistic regression; the independent variables were access to social security health services, age, education, housing quality, and place of residence (urban or rural); the dependent variable was the interview subject's familiarity with the purpose of the Pap test. The results were expressed as odds ratios with 95% confidence intervals. It was found that 41.5% of the women surveyed did not know the purpose of the Pap test, and that within this latter group, 97% had never had one. Factors found to be associated with not knowing the test's purpose were lack of access to the social security health services (OR = 1.9; 95% CI: 1.5-2.3); illiteracy (OR = 36.1; 95% CI: 17.9-72.7); and low socioeconomic level (OR = 2.9; 95% CI: 2.3-3.7). Also, rural dwellers had less familiarity with the Pap test than urban dwellers (OR = 0.5; 95% CI: 0.4-0.7). These results highlight the need to develop strategies for making the benefits of the Pap test known, bearing in mind the socioeconomic and cultural diversity of the populations involved.

    Full Text Available The purpose of this paper is to investigate the relationship between the entrepreneurship ecosystem and the entrepreneur’s willingness to grow. This study is particularly interested in exploring the relationship between entrepreneur’s familiarity with the key economic development organizations in the entrepreneurship ecosystem and the willingness to grow. Several studies have investigated the growth process in small and medium sized enterprises (SMEs since the case has been made that high growth SMEs contribute to economic growth through job creation. To date, these studies have identified multiple internal and external determinants including their effects on small business growth. There is evidence in the literature that characteristics of the entrepreneurs such as the willingness to grow and the entrepreneur’s network are important factors in growth process. However, the relationship between growth process and the entrepreneur’s networking behavior is yet to be fully understood. Drawing from the entrepreneurship ecosystem literature, the growth process literature and the resource dependence theory, this study uses the business confidence survey from 2011 to 2013, which targeted all businesses across all of Halifax Regional Municipality (HRM in Nova Scotia, Canada, to explore the relationship between the entrepreneur willingness to grow and the propensity to network with key economic development organizations of the entrepreneurial ecosystem. The findings support the assumption that the proportion of businesses that are willing to grow (i.e. hire additional staff and enter new markets within the next twelve months is higher for the group of businesses that are familiar with the key economic development organizations than for the group of businesses that are not familiar with them. However, the results are not homogeneous across all populations. Our findings also indicate that the higher the expectation to enter new markets over the next

  10. Geomorphology: the Shock of the Familiar

    Everyone experiences landscapes and has a sense about how they work: water runs down hill, it erodes and carries sediments, and that's about it, right? Introductory earth science text books are uniformly qualitative about the field, and leave one with little sense of wonder, and certainly not "shock". But four shocks occur if one peels away the first impressions. First, landscapes are surprisingly similar: the same forms are repeated in virtually all environments, including under the ocean and on other planets. Second, we lack theory and mechanistic observations to answer many simple first-order questions, e.g. what controls the width of a river, how does rock type control hillslope form and erosion rate, or, is there a topographic signature of life. Third, there are unexpected connections between surface erosion, deep earth processes, and climate. And fourth, the field itself, despite having been a subject of study for well over 100 years, is currently experiencing a revolution of ideas and discoveries through new tools, observatories, centers, journals, books, contributions of researchers from other disciplines, and from a significant hiring of young researchers in geomorphology. Deep messages await discovery in the simple landforms surrounding us.

  13. Visual laterality in dolphins: importance of the familiarity of stimuli

    2012-01-01

    Background Many studies of cerebral asymmetries in different species lead, on the one hand, to a better understanding of the functions of each cerebral hemisphere and, on the other hand, to develop an evolutionary history of hemispheric laterality. Our animal model is particularly interesting because of its original evolutionary path, i.e. return to aquatic life after a terrestrial phase. The rare reports concerning visual laterality of marine mammals investigated mainly discrimination processes. As dolphins are migrant species they are confronted to a changing environment. Being able to categorize new versus familiar objects would allow dolphins a rapid adaptation to novel environments. Visual laterality could be a prerequisite to this adaptability. To date, no study, to our knowledge, has analyzed the environmental factors that could influence their visual laterality. Results We investigated visual laterality expressed spontaneously at the water surface by a group of five common bottlenose dolphins (Tursiops truncatus) in response to various stimuli. The stimuli presented ranged from very familiar objects (known and manipulated previously) to familiar objects (known but never manipulated) to unfamiliar objects (unknown, never seen previously). At the group level, dolphins used their left eye to observe very familiar objects and their right eye to observe unfamiliar objects. However, eyes are used indifferently to observe familiar objects with intermediate valence. Conclusion Our results suggest different visual cerebral processes based either on the global shape of well-known objects or on local details of unknown objects. Moreover, the manipulation of an object appears necessary for these dolphins to construct a global representation of an object enabling its immediate categorization for subsequent use. Our experimental results pointed out some cognitive capacities of dolphins which might be crucial for their wild life given their fission-fusion social system

We believe that try this situation means to live with limitations and wearings in the familiar everyday, what makes difficult the living with the psychotic person. Considering these aspects, this research has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It is about a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state, called Ijuí. The people of the investigation are composed of five psychotic’s parents, which frequent the socioterapy group in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all. The analysis of the obtained data followed MINAYO’s (2002 methodological proposition. By the contained information in the stud’s social actor’s declarations, emerged three thematic with a similar nucleus of thoughts. On first thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in the moment he has the acute symptoms. On the second thematic, we talked about the medical question as bring a therapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematic shows the family conception about mental sickness. With this research we concluded that the living with a mental sick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed by the sick person. Besides that, the family considers the medication one of the most important possibilities of intervention in the psychotic’s therapy, what is reinforced by the health team that leads with these people.

    This research questioned the proposition that corporate familiarity is positively associated with firm reputation. Student images of familiar and unfamiliar Fortune 500 corporations were examined in 4 experiments. The results suggested that, consistent with behavioral decision theory and attitude theory, highly familiar corporations provide information that is more compatible with the tasks of both admiring and condemning than less familiar corporations. Furthermore, the judgment context may determine whether positive or negative judgments are reported about familiar companies. The notion that people can simultaneously hold contradictory images of well-known firms may help to explain the inconsistent findings on the relation between familiarity and reputation.

    Brain responses to feed flavors with or without a feed additive (FA) were investigated in piglets familiarized or not with this FA. Sixteen piglets were allocated to 2 dietary treatments from weaning until d 37: the naive group (NAI) received a standard control feed and the familiarized group (FAM) received the same feed added with a FA mainly made of orange extracts. Animals were subjected to a feed transition at d 16 post-weaning, and to 2-choice feeding tests at d 16 and d 23. Production traits of the piglets were assessed up to d 28 post-weaning. From d 26 onwards, animals underwent 2 brain imaging sessions (positron emission tomography of 18FDG) under anesthesia to investigate the brain activity triggered by the exposure to the flavors of the feed with (FA) or without (C) the FA. Images were analyzed with SPM8 and a region of interest (ROI)-based small volume correction (p reward, and included the prefrontal cortex, insular cortex, fusiform gyrus, limbic system and corpus striatum. The FAM animals showed a moderate preference for the novel post-transition FA feed compared to the C feed on d 16, i.e., day of the feed transition (67% of total feed intake). The presence or absence of the FA in the diet from weaning had no impact on body weight, average daily gain, and feed efficiency of the animals over the whole experimental period (p ≥ 0.10). Familiar feed flavors activated the prefrontal cortex. The amygdala, insular cortex, and prepyriform area were only activated in familiarized animals exposed to the FA feed flavor. The perception of FA feed flavor in the familiarized animals activated the dorsal striatum differently than the perception of the C feed flavor in naive animals. Our data demonstrated that the perception of FA in familiarized individuals induced different brain responses in regions involved in reward anticipation and/or perception processes than the familiar control feed flavor in naive animals. Chronic exposure to the FA might be necessary

MÉTODOS: Participaram 20 díades de crianças com gagueira e familiares. Os procedimentos foram realizados em três etapas: avaliação da fluência, orientações familiares e reavaliação da fluência. A avaliação inicial da fluência foi realizada para caracterizar a tipologia e a frequência das disfluências antes das orientações. A orientação familiar foi realizada em duas sessões, enfatizando os comportamentos verbais e não verbais da família que podem promover a fluência na criança. A reavaliação da fluência ocorreu depois de trinta dias, utilizando-se os mesmos procedimentos da avaliação inicial. Foi aplicado o Teste dos Postos Sinalizados de Wilcoxon, para medir o grau de significância da diferença entre as informações obtidas nas duas fases. RESULTADOS: No que se refere à tipologia, a análise comparativa das duas avaliações mostrou que, dentre os seis tipos de disfluências comuns, quatro diminuíram, e, dentre os seis tipos de disfluências gagas, cinco apresentaram redução. No que se refere à frequência das rupturas, 70% das crianças tiveram uma diminuição na porcentagem de descontinuidade de fala, e 80% no total de rupturas gagas. CONCLUSÃO: A orientação fonoaudiológica realizada com familiares de crianças com gagueira favoreceu a promoção da fluência na fala da criança, mostrando-se relevante na área da fluência infantil.PURPOSE: To determine the contribution of short-term familiar counseling in the speech fluency of children who stutter.

    Wide-ranging animals, such as birds, regularly traverse large areas of the landscape efficiently in the course of their local movement patterns, which raises fundamental questions about the cognitive mechanisms involved. By using precision global-positioning-system loggers, we show that homing pigeons (Columba livia) not only come to rely on highly stereotyped yet surprisingly inefficient routes within the local area but are attracted directly back to their individually preferred routes even when released from novel sites off-route. This precise route loyalty demonstrates a reliance on familiar landmarks throughout the flight, which was unexpected under current models of avian navigation. We discuss how visual landmarks may be encoded as waypoints within familiar route maps.

    Full Text Available Many people are encountered with finding the best way to reach to their destination. One definition for wayfinding is “the act of travelling to the destination by continuous processes of making route-choices whilst evaluating previous spatial decisions against stable cognition of the environment.  General understanding and keen appraisal of the environment can aid decision-making process of how to navigate around an area in the form of mental schemas. However, having a level of familiarity and attachment to a place is the underlying factor. The study is aimed at evaluating what is the level of familiarity of people and what is their attachment to notable landmarks in the town of Muar, Malaysia. To do so, the traditional survey analysis with the focus on data set that is attributed to a specific phenomenon and the quantifiable variable using statistical analysis on the tabularized format is undertaken.

    In contemporary dance, cognitive events are not necessarily restricted "to the skin or skull of an individual" (Hutchins in Int Encycl Soc Behav Sci 2068-2072, 2001) but distributed across dancers during collaborative improvisation. There is some experimental evidence of greater output when people perform problem-solving tasks alone. However, when a task is challenging and paired participants are familiar with each other, pairwise and emergent outcomes are more plentiful than solo outcomes. We investigate these factors in the context of dance with the broad hypothesis that innovation is enhanced when dancers improvise together compared with when they improvise alone. Dancers (N = 10) in a professional company improvised for 2 min alone and then with another dancer. Dancer familiarity (familiar, unfamiliar) and task (expressive, non-expressive) were crossed (within-subjects). The improvisations were video-recorded over 2 h in the dancers' usual improvisation space. After each improvisation, the dancers: stated the number of movement ideas expressed and rated task ease, satisfaction, interest, novelty, originality and clarity. In both tasks, there was a tendency for self-report of a greater number of movement ideas expressed in familiar and unfamiliar pairs than alone. Ratings of task ease, satisfaction, interest, clarity, etc. were slightly higher in the unfamiliar pair condition. In the non-expressive task, ratings of the task were higher in pairs (M = 3.02, SD 0.82) than in the solo (M = 2.67, SD 0.96) condition. Distributed creativity, relational cognition and social facilitation are used to interpret the results.

    Full Text Available A lot of people live situations of mental sickness, from psychotic character, that can cause sufferingboth for the sick and his family. We believe that try this situation means to live with limitations and wearings in thefamiliar everyday, what makes difficult the living with the psychotic person. Considering these aspects, thisresearch has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It isabout a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state,called Ijuí. The people of the investigation are composed of five psychotic’s parents, which frequent the socioterapygroup in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all.The analysis of the obtained data followed MINAYO’s (2002 methodological proposition. By the containedinformation in the stud’s social actor’s declarations, emerged three thematic with a similar nucleus of thoughts. Onfirst thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in themoment he has the acute symptoms. On the second thematic, we talked about the medical question as bring atherapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematicshows the family conception about mental sickness. With this research we concluded that the living with a mentalsick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed bythe sick person. Besides that, the family considers the medication one of the most important possibilities ofintervention in the psychotic’s therapy, what is reinforced by the health team that leads with these people.

  17. A familiar font drives early emotional effects in word recognition.

    Science.gov (United States)

    Kuchinke, Lars; Krause, Beatrix; Fritsch, Nathalie; Briesemeister, Benny B

    2014-10-01

    The emotional connotation of a word is known to shift the process of word recognition. Using the electroencephalographic event-related potentials (ERPs) approach it has been documented that early attentional processing of high-arousing negative words is shifted at a stage of processing where a presented word cannot have been fully identified. Contextual learning has been discussed to contribute to these effects. The present study shows that a manipulation of the familiarity with a word's shape interferes with these earliest emotional ERP effects. Presenting high-arousing negative and neutral words in a familiar or an unfamiliar font results in very early emotion differences only in case of familiar shapes, whereas later processing stages reveal similar emotional effects in both font conditions. Because these early emotion-related differences predict later behavioral differences, it is suggested that contextual learning of emotional valence comprises more visual features than previously expected to guide early visual-sensory processing.

    Full Text Available La familia es el grupo a través del cual se gestiona la mayor parte de los movimientos de dinero entre la provincia de Quebec y Colombia, y por lo común son destinados a la subsistencia familiar cotidiana. Los flujos de dinero entre ambos territorios se producen en el seno de la mayoría de las familias, tienen una frecuencia muy variada y los montos involucrados son modestos. Los testimonios recogidos entre las personas que mandan dinero a sus familiares en Colombia revelan que, para la mayoría de ellas, la frecuencia y los montos que envían se reducen una vez que se han asentado en la provincia de Quebec, en comparación con la situación previa al exilio. Para muchos de ellos, el papel de proveedor económico que desempeñaban dentro de su familia se ha reducido de manera considerable; y para otros inclusive desaparece. De manera general, se puede afirmar que no se producen cambios importantes en lo que se refiere a las intenciones de las personas en colaborar económicamente con sus familiares al salir en exilio. Los cambios se producen en las posibilidades concretas de hacerlo, las cuales disminuyen o desaparecen.

    The present study concerned how the acquisition of social information, specifically knowledge about personal characteristics, influences young children's memory and suggestibility. Effects of two sources of knowledge about a target person were systematically examined: familiarity and stereotypes. Children, aged 4-5 and 7-9 years (N = 145), were randomly assigned, per age group, to experimental conditions based on a familiarity (6 hours vs. no prior exposure) × stereotype (negative depiction as messy and clumsy vs. no stereotype) factorial design. Children then watched the target person engage in a target event (a series of contests) at a preschool ("Camp Ingrid"). The children's memory and suggestibility about the target person and target event were tested after a delay of 2 weeks. Results indicated that the negative stereotype resulted in an increase in children's correct responses both to free-recall stereotype-related questions (when children were unfamiliar with the target person) and to closed-ended questions overall (for younger children). However, the stereotype was associated with greater error to stereotype-related closed-ended questions. Moreover, familiarity increased children's accuracy to closed-ended questions. Implications for theory and application are discussed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    Introduzione: le patologie del bambino, soprattutto se gravi e durature, possono essere definite come “malattie della famiglia” a causa dell’intensità di assistenza richiesta, delle difficoltà organizzative quotidiane e dello stress causato. Obiettivo: identificare il ruolo di alcuni potenziali fattori di rischio coinvolti nella rottura di famiglie di bambini leucemici.

    Materiali e metodi: mediante l’uso di questionari, sono state studiate, durante l’anno 2002, 150 cartelle cliniche di bambini leucemici dell’ospedale pediatrico “Santobono-Pausillipon”- Dipartimento di Oncologia; 11 casi sono stati esclusi per incompletezza dei dati. Outcome è stata considerata la “separazione familiare.” Sono state analizzate le seguenti variabili: trapianto di midollo osseo, lavoro del padre, della madre e loro età ed educazione, sesso ed età del bambino (CA, numerosità della famiglia, stato socio-economico, probabilità clinica di guarire (CPR, appartenenza ad una associazione. Sono state condotte analisi bivariate e logistiche. Risultati: all’analisi bivariata CA e CPR, entrambi stratificati in tre livelli, sono risultati associati alla separazione. L’Odds Ratio grezzo (OR della separazione familiare con CA di 5/10 anni e bambini di 11 anni o più a confronto con quelli d’età di 0/4 era, rispettivamente, di 8.68 (p=0.02 e di 5.7 (p=0.07. L’OR grezzo della separazione con un CPR medio e un CPR buono confrontato con un CPR basso ha dato rispettivamente 0.35 (p=0.02 e 0.08 (p‹0.001. Un modello logistico che includeva CPR come variabile principale e controllata per CA ha evidenziato che la probabilità di guarigione è media o alta e, dopo aver aggiustato per l’età del bambino, è stato ottenuto un rischio di rottura familiare rispettivamente di 0.29 (p=0.01 e 0.08 (p=0.02.

    2017-12-01

    Evolution in the form of selective breeding has long been harnessed as a useful tool by humans. However, rapid evolution can also be a danger to our health and a stumbling block for biotechnology. Unwanted evolution can underlie the emergence of drug and pesticide resistance, cancer, and weeds. It makes live vaccines and engineered cells inherently unreliable and unpredictable, and therefore potentially unsafe. Yet, there are strategies that have been and can possibly be used to stop or slow many types of evolution. We review and classify existing population genetics-inspired methods for arresting evolution. Then, we discuss how genome editing techniques enable a radically new set of approaches to limit evolution. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Nevertheless the criticism of various economy sectors and international organisms to the production of bio fuels, the Brazilian Government are giving incentives for that production since the year of 2004, when they launched an incentive program for the production of oleaginous species which are the raw material for the production of bio diesel, emphasizing the support to familiar agriculture. However, there are serious questionings about the real contribution of these fuels for the sustainability not only of the planet, but also the population, taking into consideration the possible social and environmental impacts of the implementation of their policies. This paper tries to debate all those problems through the analysis of the possible effects of the Brazilian policies of incentive to the bio diesel production for the family farmers from the semi-arid of the state of Bahia, Brazil. The paper intends to evaluate if this type of production is a real alternative for the sustainability of the familiar agriculture, and if there is another model of more adequate management for the production of oleaginous for bio diesel by the familiar agriculture.

    This book explains how dual phase evolution operates in all these settings and provides a detailed treatment of the subject. The authors discuss the theoretical foundations for the theory, how it relates to other phase transition phenomena and its advantages in evolutionary computation and complex adaptive systems. The book provides methods and techniques to use this concept for problem solving. Dual phase evolution concerns systems that evolve via repeated phase shifts in the connectivity of their elements. It occurs in vast range of settings, including natural systems (species evolution, landscape ecology, geomorphology), socio-economic systems (social networks) and in artificial systems (annealing, evolutionary computing).

    Evolution strategies have more than 50 years of history in the field of evolutionary computation. Since the early 1990s, many algorithmic variations of evolution strategies have been developed, characterized by the fact that they use the so-called derandomization concept for strategy parameter adaptation. Most importantly, the covariance matrix adaptation strategy (CMA-ES) and its successors are the key representatives of this group of contemporary evolution strategies. This book provides an overview of the key algorithm developments between 1990 and 2012, including brief descriptions of the a

    Chiroptera is the second largest order among mammals, with over 1300 species in 21 extant families. The group is extremely diverse in several aspects of its natural history, including dietary strategies, ecology, behavior and morphology. Bat genomes show ample chromosome diversity (from 2n = 14 to 62). As with other mammalian orders, Chiroptera is characterized by clades with low, moderate and extreme chromosomal change. In this article, we will discuss trends of karyotypic evolution within distinct bat lineages (especially Phyllostomidae, Hipposideridae and Rhinolophidae), focusing on two perspectives: evolution of genome architecture, modes of chromosomal evolution, and the use of chromosome data to resolve taxonomic problems.

    2008-07-01

    Full Text Available Abstract Background It has been suggested that the variability among studies in the onset of lexical effects may be due to a series of methodological differences. In this study we investigated the role of orthographic familiarity, phonological legality and number of orthographic neighbours of words in determining the onset of word/non-word discriminative responses. Methods ERPs were recorded from 128 sites in 16 Italian University students engaged in a lexical decision task. Stimuli were 100 words, 100 quasi-words (obtained by the replacement of a single letter, 100 pseudo-words (non-derived and 100 illegal letter strings. All stimuli were balanced for length; words and quasi-words were also balanced for frequency of use, domain of semantic category and imageability. SwLORETA source reconstruction was performed on ERP difference waves of interest. Results Overall, the data provided evidence that the latency of lexical effects (word/non-word discrimination varied as a function of the number of a word's orthographic neighbours, being shorter to non-derived than to derived pseudo-words. This suggests some caveats about the use in lexical decision paradigms of quasi-words obtained by transposing or replacing only 1 or 2 letters. Our findings also showed that the left-occipito/temporal area, reflecting the activity of the left fusiform gyrus (BA37 of the temporal lobe, was affected by the visual familiarity of words, thus explaining its lexical sensitivity (word vs. non-word discrimination. The temporo-parietal area was markedly sensitive to phonological legality exhibiting a clear-cut discriminative response between illegal and legal strings as early as 250 ms of latency. Conclusion The onset of lexical effects in a lexical decision paradigm depends on a series of factors, including orthographic familiarity, degree of global lexical activity, and phonologic legality of non-words.

    Previous research documents the under-utilization of hospice services by minority ethnic groups, but less data exist for Asian and Hispanic Americans. It is unclear whether these low utilization rates are a result of attitudinal or information barriers, or both. To examine self-reported familiarity and attitudes toward hospice among Asian and Hispanic groups in ethnically diverse Queens County, NY. We surveyed diverse adults during health fairs, at senior centers, and church programs directed at ethnic populations. Respondents completed surveys in their preferred language: Spanish, Chinese (Mandarin), and Korean. Analysis of variance was used to compare continuous variables among language groups; Fisher's exact test compared categorical variables. A total of 604 community adults were surveyed: 99 Chinese, 349 Korean, 156 Spanish. Respondents were mostly female, average age 53 years. Familiarity with hospice varied significantly among the groups (P < 0.001) and was lower in the Hispanic (16%) and higher in the Chinese (45%) and Korean (56%) groups. Personal experiences with hospice were low (8-16%) in all groups. A majority (75-94%) responded they would share hospice information with loved ones, but the Hispanic group was significantly less likely to do so compared with Chinese and Korean Americans. Between 74 and 95% reported willingness to receive future information about hospice, but the Korean group was significantly less likely to want information. When surveyed in their preferred language, Asian and Hispanic adults reported variable levels of familiarity with hospice services. Most responded positively to receiving future information and would tell friends and family members about hospice. Copyright © 2015 American Academy of Hospice and Palliative Medicine.

    Faces are an important visual category for many taxa, and the human face is no exception to this. Because faces differ in subtle ways and possess many idiosyncratic features, they provide a rich source of perceptual cues. A fair amount of those cues are learned through social interactions and are used for future identification of individual humans. These effects of individual experience can be studied particularly well in hetero-specific face perception. Domestic dogs represent a perfect model in this respect, due to their proved ability to extract important information from the human face in socio-communicative interactions. There is also suggestive evidence that dogs can identify their owner or other familiar human individuals by using visual information from the face. However, most studies have used only dogs’ looking behavior to examine their visual processing of human faces and it has been demonstrated only that dogs can differentiate between familiar and unknown human faces. Here, we examined the dog's ability to discriminate the faces of two familiar persons by active choice (approach and touch). Furthermore, in successive stages of the experiment we investigated how well dogs discriminate humans in different representations by systematically reducing the informational richness and the quality of the stimuli. We found a huge inter-individual and inter-stage variance in performance, indicating differences across dogs in their learning ability as well as their selection of discriminative cues. On a group level, the performance of dogs significantly decreased when they were presented with pictures of human heads after having learned to discriminate the real heads, and when – after relearning – confronted with the same pictures showing only the inner parts of the heads. However, as two dogs quickly mastered all stages, we conclude that dogs are in principle able to discriminate people on the basis of visual information from their faces and by making active

  4. Cambio familiar y maltrato conyugal a la mujer

    Full Text Available According to family resources theory, the empowerment of women caused by the different dimensions of family change during the last decades (deinstitutionalization of the family, female work, higher education, etc has brought about a greater say in the process of negotiation of gender roles inside the family and the couple life. This impowerment of women should have implied also a lower degree of partner violence against women in “modern” family life settings. Based on a survey on violence against women carried out in 1999 in Spain among 20.000 women, the paper analyses using logistic regressions models if different dimensions of family change (female work, cohabitation, among others are associated with lower risks of partner violence against women. Results from such type of analyses show that there is little support to suppose that family change and the corresponding empowerment of women which it implies will bring about a lower risk of partner violence against women.

    Según la teoría de los recursos, la ganancia de recursos de poder por parte de las mujeres derivada de las distintas dimensiones del cambio familiar (desintitucionalización de la familia, incorporación de la mujer al mercado de trabajo, mayor nivel educativo, etc. ha comportado un mayor poder de negociación del contenido de los roles familiares y domésticos. Esta ganancia en recursos de poder debería haberse traducido en una menor violencia conyugal contra las mujeres que viven en uniones “modernas”. A partir de la macroencuesta sobre violencia de género realizada por el Instituto de la Mujer en 1999 se analiza si las distintas dimensiones del cambio familiar están asociadas con un menor riesgo de maltrato. Los resultados obtenidos mediante ajustes de regresión logística indican que el cambio familiar y el correspondiente aumento de poder de negociación de las mujeres no se ha traducido automáticamente en una reducción del riesgo de maltrato.

  11. Cultural Evolution and SETI

    Dick, S. J.

    2009-12-01

    The Drake Equation for the number of radio communicative technological civilizations in the Galaxy encompasses three components of cosmic evolution: astronomical, biological and cultural. Of these three, cultural evolution totally dominates in terms of the rapidity of its effects. Yet, SETI scientists do not take cultural evolution into account, perhaps for understandable reasons, since cultural evolution is not well-understood even on Earth and is unpredictable in its outcome. But the one certainty for technical civilizations billions, millions, or even thousands of years older than ours is that they will have undergone cultural evolution. Cultural evolution potentially takes place in many directions, but this paper argues that its central driving force is the maintenance, improvement and perpetuation of knowledge and intelligence, and that to the extent intelligence can be improved, it will be improved. Applying this principle to life in the universe, extraterrestrials will have sought the best way to improve their intelligence. One possibility is that they may have long ago advanced beyond flesh-and-blood to artificial intelligence, constituting a postbiological universe. Although this subject has been broached, it has not been given the attention it is due from its foundation in cultural evolution. Nor has the idea of a postbiological universe been carried to its logical conclusion, including a careful analysis of the implications for SETI. SETI scientists, social scientists, and experts in AI should consider the strengths and weaknesses of this new paradigm.

  13. Knowing too little or too much: The effects of familiarity with a co-performer’s part on interpersonal coordination in musical ensembles

    Full Text Available Expert ensemble musicians produce exquisitely coordinated sounds, but rehearsal is typically required to do so. Ensemble coordination may thus be influenced by the degree to which individuals are familiar with each other’s parts. Such familiarity may affect the ability to predict and synchronize with co-performers’ actions. Internal models related to action simulation and anticipatory musical imagery may be affected by knowledge of (1 the musical structure of a co-performer’s part (e.g., in terms of its rhythm and phrase structure and/or (2 the co-performer’s idiosyncratic playing style (e.g., expressive micro-timing variations. The current study investigated the effects of familiarity on interpersonal coordination in piano duos. Skilled pianists were required to play several duets with different partners. One condition included duets for which co-performers had previously practiced both parts, while another condition included duets for which each performer had practiced only their own part. Each piece was recorded six times without joint rehearsal or visual contact to examine the effects of increasing familiarity. Interpersonal coordination was quantified by measuring asynchronies between pianists’ keystroke timing and the correlation of their body (head and torso movements, which were recorded with a motion capture system. The results suggest that familiarity with a co-performer’s part, in the absence of familiarity with their playing style, engenders predictions about micro-timing variations that are based instead upon one’s own playing style, leading to a mismatch between predictions and actual events at short timescales. Predictions at longer timescales—that is, those related to musical measures and phrases, and reflected in head movements and body sway—are, however, facilitated by familiarity with the structure of a co-performer’s part. These findings point to a dissociation between interpersonal coordination at the

    Understanding public perceptions of biodiversity is essential to ensure continued support for conservation efforts. Despite this, insights remain scarce at broader spatial scales, mostly due to a lack of adequate methods for their assessment. The emergence of new technologies with global reach and high levels of participation provide exciting new opportunities to study the public visibility of biodiversity and the factors that drive it. Here, we use a measure of internet saliency to assess the national and international visibility of species within four taxa of Brazilian birds (toucans, hummingbirds, parrots and woodpeckers), and evaluate how much of this visibility can be explained by factors associated with familiarity, aesthetic appeal and conservation interest. Our results strongly indicate that familiarity (human population within the range of a species) is the most important factor driving internet saliency within Brazil, while aesthetic appeal (body size) best explains variation in international saliency. Endemism and conservation status of a species had small, but often negative, effects on either metric of internet saliency. While further studies are needed to evaluate the relationship between internet content and the cultural visibility of different species, our results strongly indicate that internet saliency can be considered as a broad proxy of cultural interest.

Cross-sectional study using a structured questionnaire. The study was conducted during the 50th Annual Scientific Conference of the West African College of Surgeons, which was held in Calabar, Nigeria, from 6th to It 12th February 2010. One hundred and ten out of 150 surgeons who were attending the conference returned their filled questionnaires. Their familiarity with business and financial concepts was lacking on crucial ones related to marketing strategies. Respondent largely found the listed objections to advertisement of medical services as very appropriate. They preferred largely to interact with themselves in professional associations rather than with others in cross-cultural groupings. Funding (66.4%) and political/ethnic influences (43.9%) were rated as impacting very negatively on their health institutions, while the deployment of information communication technology to institutional processes was adjudged to be unsatisfactory. Most of the indices of core competencies in modern health leadership and management appeared deficient among our study participants and their health institutions managerial environments were equally deficient. We recommend for a well-focussed short time duration health management course for all physicians particularly specialists.

A amostra foi composta por 12 participantes atendidas em hospital universitário. Os instrumentos utilizados foram: roteiro de entrevista semiestruturada, Mapa de Rede e Genograma. Os resultados indicaram que as redes sociais das participantes têm configuração restrita, com proeminência de membros da família em sua composição. Os relacionamentos familiares oscilam, contudo, entre turbulência e distanciamento afetivo. As relações de afeto mantidas com pais, cônjuges e namorados são marcadas por divergências e insatisfações. A baixa densidade da rede de amizades e o empobrecimento da vida social resultam em isolamento e dificuldades de dar início e/ou manter relacionamentos afetivos duradouros.

Este artigo analisa as estratégias desses produtores em relação à divisão de herança e à sucessão, e as formas que utilizam para aquisição de novas áreas. O levantamento das características das famílias e da propriedade foi realizado por meio de um questionário aplicado junto a 89 produtores familiares de três municípios da mesorregião de São José do Rio Preto (SP. Posteriormente foi entrevistado um terço dos produtores de cada município que havia respondido ao questionário. A análise das estratégias fundiárias mostrou uma grande diversidade na forma de partilhar a herança e de conduzir a sucessão, sendo que ambos os processos são apoiados, basicamente, em regras tradicionais, embora mantenham uma fachada de adequação às normas legais. Quanto às estratégias de aquisição de mais terras, observou-se que os produtores são capazes de organizar complexas formas de capitalização, centradas em maiores esforços no trabalho e na contenção de gastos, além da utilização de políticas públicas favoráveis e de práticas costumeiras. Os arranjos intra-familiares e as formas de cooperação ligadas ao parentesco mais amplo também se mostraram importantes para a ampliação da propriedade.The maintenance and/or expansion of land form the central axle along which family farming organize their livelihood and work..

    Full Text Available When a city that is rarely featured on television is used in a television series, local audiences get enthusiastic. Locations featured on screen have particular cultural values to those living close to these television locations. This article expands on local audiences’ experiences by using a case study of the Dutch television series Smeris. Besides analysing the series and metadata, audience research, including Tweets and interviews, was conducted. While the first season of Smeris is set in Tilburg, the second season is mainly filmed in the capital Amsterdam. The normality of viewing Amsterdam on the screen is contrasted against the novel and special, yet familiar, experience of seeing Tilburg. Precisely because Tilburg is rarely featured on television, local audiences play with this physical place in relation to the place as featured on television. Local audiences may display their pride in this repositioning of Tilburg as a central figure. Locals may engage with the (mistakes within the used mediated familiar locations. Moreover, residents may mix elements of reality (e.g. news articles with events from the series. Thus, locals engage with this television series in for them new ways through mixing the places with their imagination.

    This pilot study examined the feasibility, acceptability, and preliminary outcomes of a linguistically and culturally adapted intervention for immigrant Latina mothers with depression and their families. Fortalezas Familiares (Family Strengths) is a community-based, 12-week, multifamily group intervention that aims to increase communication about family processes leading up to and affected by the mother's depression, build child coping and efficacy, enhance parenting competence and skills, and promote cultural and social assets within the family. In terms of feasibility, of 16 families who enrolled and participated in the intervention, 13 families attended more than 90% of meetings and completed the intervention. Posttests reported positive changes following the intervention, including improved psychological functioning, increased family and marital support, and enhanced family functioning, as reported by mothers and other caregivers. Mothers also reported decreased conduct and hyperactivity problems among their children. Children reported positive changes in their psychological functioning and coping, parenting warmth and acceptance, and overall family functioning. Postintervention focus groups and surveys measuring acceptability revealed families' satisfaction with the intervention and suggested areas of improvement. We discuss similarities and differences in outcomes between the adapted intervention, Fortalezas Familiares, and the original intervention, Keeping Families Strong, and propose future areas of intervention adaptation and development. © FPI, Inc.

    Andersen, Esben Sloth

    This draft of a book on Schumpeter is distributed for commenting. It is a stylised intellectual biography that focus on the emergence and extension of the Schumpeterian vision and analysis of economic and social evolution. The draft provides novel interpretations of Schumpeter's six major books. He...... originally developed his evolutionary research programme in Wesen from 1908 by studying the inherent limitations of Neoclassical Economics. He presented core results on economic evolution and sketched an extension evolutionary analysis to all social sciences in Entwicklung from 1912. He made a partial...... reworking of his basic theory of economic evolution in Development from 1934, and this reworking was continued in Cycles from 1939. Here Schumpeter also tried to handle the statistical and historical evidence on the waveform evolution of the capitalist economy. Capitalism from 1942 modified the model...

    Full Text Available This article reviews the family constellation of patients with obsessive compulsive disorder (OCD, the presence of OCD symptoms among family members, and familial aspects including parental attachment, expressed emotion (EE, and family accommodation. Some evidence supports a negative effect of hostility, emotional over-involvement, and criticism perceived by the patient on behavioral treatment outcome. However, actual criticism observed by the relative during an interview was associated with more benefit from therapy. Family accommodation predicted poorer family functioning and more severe OCD symptoms after behavioral treatment. A review of the limited treatment literature indicates no actual tests of the effects of psycho-educational and supportive treatments, although several reports suggest they are useful for families and patients. Including relatives in treatment has proved beneficial in some studies, especially with children, but not in others. Multiple family groups that focus on behavioral contracting for exposure and stopping rituals may be a promising intervention. Likewise, efforts to reduce family accommodation in the context of behavioral treatment have proved useful. Additional research on the content, process and effects of family interventions for OCD is much needed.Esse artigo revisa a constelação familiar dos pacientes com transtorno obsessivo-compulsivo (TOC, a presença de sintomas obsessivo-compulsivo entre os familiares e aspectos familiares como relacionamento parental, expressividade emocional e acomodação familiar.

    2011-08-01

    Papers using qualitative methods are increasingly common in psychiatric journals. This overview is an introduction to critically appraising a qualitative paper for clinicians who are more familiar with quantitative methods. Qualitative research uses data from interviews (semi-structured or unstructured), focus groups, observations or written materials. Data analysis is inductive, allowing meaning to emerge from the data, rather than the more deductive, hypothesis centred approach of quantitative research. This overview compares and contrasts quantitative and qualitative research methods. Quantitative concepts such as reliability, validity, statistical power, bias and generalisability have qualitative equivalents. These include triangulation, trustworthiness, saturation, reflexivity and applicability. Reflexivity also shares features of transference. Qualitative approaches include: ethnography, action-assessment, grounded theory, case studies and mixed methods. Qualitative research can complement quantitative approaches. An understanding of both is useful in critically appraising the psychiatric literature.

Ao mesmo tempo, vem sendo apontada como um indicador de confiança dos investidores nas decisões tomadas pela administração das empresas listadas em bolsas de valores. Uma das formas de avaliar as estruturas e práticas de governança corporativa é verificar a sensibilidade do turnover de executivos ao desempenho da firma (VOLPIN, 2002. Neste artigo, objetiva-se verificar a existência de diferenças significativas de desempenho, valor e estruturas de governança corporativa entre empresas familiares e não-familiares; e, ainda, a existência de associações entre performance e turnover de executivos, tendo em vista a atuação da governança corporativa. A análise é conduzida tomando como referência um conjunto de 176 empresas industriais listadas na Bovespa, segmentadas por tipo (familiar ou não-familiar, entre 1997 e 2001. A contribuição do estudo se dá pelas peculiaridades que envolvem as empresas familiares, que não têm sido consideradas em pesquisas brasileiras, e pelo oferecimento de elementos para refletir teoricamente o desempenho das empresas familiares e suas estruturas de governança. Os resultados alcançados revelam a existência de diferenças significativas de desempenho, valor e estruturas de governança corporativa entre empresas familiares e não-familiares. É possível verificar ainda que, nas empresas familiares, quanto maior a rentabilidade, menores são os níveis de turnover.

    2005-01-01

    Full Text Available Three experiments are reported showing that the perception and the assessment of veridicality of familiar faces are highly adaptive to new visual information. Subjects were asked to discriminate between real photographs and altered versions of celebrities. Exposing participants to extremely deviated versions changed the usually stable representations of the famous faces within a very short time. In Experiment 1, exposure to an extreme face version resulted in identity decisions shifted towards the exposed one. Experiment 2 revealed that the effects are not short lasting. In Experiment 3, we showed that the effect also generalizes to different pictures of the same famous person. Together the experiments seem to indicate that the brain permanently adapts to new perceptual information and integrates new data within already elaborated representations in a fast way.

  19. Fornix microstructure correlates with recollection but not familiarity memory.

    2009-11-25

    The fornix is the main tract between the medial temporal lobe (MTL) and medial diencephalon, both of which are critical for episodic memory. The precise involvement of the fornix in memory, however, has been difficult to ascertain since damage to this tract in human amnesics is invariably accompanied by atrophy to surrounding structures. We used diffusion-weighted imaging to investigate whether individual differences in fornix white matter microstructure in neurologically healthy participants were related to differences in memory as assessed by two recognition tasks. Higher microstructural integrity in the fornix tail was found to be associated with significantly better recollection memory. In contrast, there was no significant correlation between fornix microstructure and familiarity memory or performance on two non-mnemonic tasks. Our findings support the idea that there are distinct MTL-diencephalon pathways that subserve differing memory processes.

  20. Episodic and Semantic Memory Contribute to Familiar and Novel Episodic Future Thinking.

    2016-01-01

    Increasing evidence indicates that episodic future thinking (EFT) relies on both episodic and semantic memory; however, event familiarity may importantly affect the extent to which episodic and semantic memory contribute to EFT. To test this possibility, two behavioral experiments were conducted. In Experiment 1, we directly compared the proportion of episodic and semantic memory used in an EFT task. The results indicated that more episodic memory was used when imagining familiar future events compared with novel future events. Conversely, significantly more semantic memory was used when imagining novel events compared with familiar events. Experiment 2 aimed to verify the results of Experiment 1. In Experiment 2, we found that familiarity moderated the effect of priming the episodic memory system on EFT; particularly, it increased the time required to construct a standard familiar episodic future event, but did not significantly affect novel episodic event reaction time. Collectively, these findings support the hypothesis that event familiarity importantly moderates episodic and semantic memory's contribution to EFT.

    The current study presents ratings by 540 Spanish native speakers for dominance, familiarity, subjective age of acquisition (AoA), and sensory experience (SER) for the 875 Spanish words included in the Madrid Affective Database for Spanish (MADS). The norms can be downloaded as supplementary materials for this manuscript from https://figshare.com/s/8e7b445b729527262c88 These ratings may be of potential relevance to researches who are interested in characterizing the interplay between language and emotion. Additionally, with the aim of investigating how the affective features interact with the lexicosemantic properties of words, we performed correlational analyses between norms for familiarity, subjective AoA and SER, and scores for those affective variables which are currently included in the MADs. A distinct pattern of significant correlations with affective features was found for different lexicosemantic variables. These results show that familiarity, subjective AoA and SERs may have independent effects on the processing of emotional words. They also suggest that these psycholinguistic variables should be fully considered when formulating theoretical approaches to the processing of affective language.

    Adapting to the visual characteristics of a specific environment may facilitate detecting novel stimuli within that environment. We monitored eye movements while subjects searched for a color target on familiar or unfamiliar color backgrounds, in order to test for these performance changes and to explore whether they reflect changes in salience from adaptation vs. changes in search strategies or perceptual learning. The target was an ellipse of variable color presented at a random location on a dense background of ellipses. In one condition, the colors of the background varied along either the LvsM or SvsLM cardinal axes. Observers adapted by viewing a rapid succession of backgrounds drawn from one color axis, and then searched for a target on a background from the same or different color axis. Searches were monitored with a Cambridge Research Systems Video Eyetracker. Targets were located more quickly on the background axis that observers were pre-exposed to, confirming that this exposure can improve search efficiency for stimuli that differ from the background. However, eye movement patterns (e.g. fixation durations and saccade magnitudes) did not clearly differ across the two backgrounds, suggesting that how the novel and familiar backgrounds were sampled remained similar. In a second condition, we compared search on a nonselective color background drawn from a circle of hues at fixed contrast. Prior exposure to this background did not facilitate search compared to an achromatic adapting field, suggesting that subjects were not simply learning the specific colors defining the background distributions. Instead, results for both conditions are consistent with a selective adaptation effect that enhances the salience of novel stimuli by partially discounting the background.

  3. Measuring and Understanding Public Opinion on Human Evolution

    Gwon, Misook

    Right-Wing-Authoritarianism personality scale. Using this uniquely rich data set I develop a model of the nature and organization of these various attitude structures. Data analyses on explanation of public acceptance or rejection of evolution indicate that the Right-wing-authoritarianism and religious factors including beliefs in God's existence, views of the Bible, frequency of church attendance, and Evangelical Protestant affiliation are significant predictors across all measures. Scientific literacy, genetic science knowledge and familiarity, in general, are another contributor to prediction of public attitudes toward evolution. On measurement validity, consistency of measurement and responses are examined. The results from data analyses reveal the effect of question wording form and context is at play. In addition, public beliefs and knowledge about evolution are not consistent, rather contradictory, and are susceptible to framing effects. As scholars of public opinion warn, we should avoid the referendum view of polls on controversial issues (Schuman 2008; Moore 2008; Bishop 2005). Findings from this research lead to two key conclusions. First, great caution should be taken interpreting poll results on human evolution. Second, for better understanding of public opinion on this issue, a modified standard question should replace the current question.

  6. Social familiarity modulates group living and foraging behaviour of juvenile predatory mites

    Science.gov (United States)

    Strodl, Markus A.; Schausberger, Peter

    2012-04-01

    Environmental stressors during early life may have persistent consequences for phenotypic development and fitness. In group-living species, an important stressor during juvenile development is the presence and familiarity status of conspecific individuals. To alleviate intraspecific conflicts during juvenile development, many animals evolved the ability to discriminate familiar and unfamiliar individuals based on prior association and use this ability to preferentially associate with familiar individuals. Assuming that familiar neighbours require less attention than unfamiliar ones, as predicted by limited attention theory, assorting with familiar individuals should increase the efficiency in other tasks. We assessed the influence of social familiarity on within-group association behaviour, development and foraging of juvenile life stages of the group-living, plant-inhabiting predatory mite Phytoseiulus persimilis. The observed groups consisted either of mixed-age familiar and unfamiliar juvenile mites or of age-synchronized familiar or unfamiliar juvenile mites or of pairs of familiar or unfamiliar larvae. Overall, familiar mites preferentially grouped together and foraged more efficiently, i.e. needed less prey at similar developmental speed and body size at maturity, than unfamiliar mites. Preferential association of familiar mites was also apparent in the inter-exuviae distances. Social familiarity was established by imprinting in the larval stage, was not cancelled or overridden by later conspecific contacts and persisted into adulthood. Life stage had an effect on grouping with larvae being closer together than nymphal stages. Ultimately, optimized foraging during the developmental phase may relax within-group competition, enhance current and future food supply needed for optimal development and optimize patch exploitation and leaving under limited food.

    We derive the evolution equation for hadronic scattering amplitude at high energy. Our derivation includes the nonlinear effects of finite partonic density in the hadronic wave function as well as the effect of multiple scatterings for scattering on dense hadronic target. It thus includes Pomeron loops. It is based on the evolution of the hadronic wave function derived in /cite{foam}. The kernel of the evolution equation defines the second quantized Hamiltonian of the QCD Reggeon Field Theory, H RFT beyond the limits considered so far. The two previously known limits of the evolution: dilute target (JIMWLK limit) and dilute projectile (KLWMIJ limit) are recovered directly from our final result. The Hamiltonian H RFT is applicable for the evolution of scattering amplitude for arbitrarily dense hadronic projectiles/targets - from 'dipole-dipole' to 'nucleus-nucleus' scattering processes.

    2015-01-01

    Background Non-medical professionals (consumers) are increasingly using the Internet to support their health information needs. However, the cognitive effort required to perform health information searches is affected by the consumer’s familiarity with health topics. Consumers may have different levels of familiarity with individual health topics. This variation in familiarity may cause misunderstandings because the information presented by search engines may not be understood correctly by the consumers. Objective As a first step toward the improvement of the health information search process, we aimed to examine the effects of health topic familiarity on health information search behaviors by identifying the common search activity patterns exhibited by groups of consumers with different levels of familiarity. Methods Each participant completed a health terminology familiarity questionnaire and health information search tasks. The responses to the familiarity questionnaire were used to grade the familiarity of participants with predefined health topics. The search task data were transcribed into a sequence of search activities using a coding scheme. A computational model was constructed from the sequence data using a Markov chain model to identify the common search patterns in each familiarity group. Results Forty participants were classified into L1 (not familiar), L2 (somewhat familiar), and L3 (familiar) groups based on their questionnaire responses. They had different levels of familiarity with four health topics. The video data obtained from all of the participants were transcribed into 4595 search activities (mean 28.7, SD 23.27 per session). The most frequent search activities and transitions in all the familiarity groups were related to evaluations of the relevancy of selected web pages in the retrieval results. However, the next most frequent transitions differed in each group and a chi-squared test confirmed this finding (Pinformation search patterns

    2006-05-01

    We can easily recognize familiar music by listening to only one or 2 of its opening bars, but the brain regions that participate in this cognitive processing remain undetermined. We used positron-emission tomography (PET) to study changes in regional cerebral blood flow (rCBF) that occur during listening to familiar music. We used a PET subtraction technique to elucidate the brain regions associated with the recognition of familiar melodies such as well-known nursery tunes. Nonmusicians performed 2 kinds of musical tasks: judging the familiarity of musical pieces (familiarity task) and detecting deliberately altered notes in the pieces (alteration-detecting task). During the familiarity task, bilateral anterior portions of bilateral temporal lobes, superior temporal regions, and parahippocampal gyri were activated. The alteration-detecting task bilaterally activated regions in the precunei, superior/inferior parietal lobules, and lateral surface of frontal lobes, which seemed to show a correlation with the analysis of music. We hypothesize that during the familiarity task, activated brain regions participate in retrieval from long-term memory and verbal and emotional processing of familiar melodies. Our results reinforced the hypothesis reported in the literature as a result of group and case studies, that temporal lobe regions participate in the recognition of familiar melodies.

    Purpose The goal of this research was to examine whether phonological familiarity exerts different effects on novel word learning for familiar vs. unfamiliar referents, and whether successful word-learning is associated with increased second-language experience. Method Eighty-one adult native English speakers with various levels of Spanish knowledge learned phonologically-familiar novel words (constructed using English sounds) or phonologically-unfamiliar novel words (constructed using non-English and non-Spanish sounds) in association with either familiar or unfamiliar referents. Retention was tested via a forced-choice recognition-task. A median-split procedure identified high-ability and low-ability word-learners in each condition, and the two groups were compared on measures of second-language experience. Results Findings suggest that the ability to accurately match newly-learned novel names to their appropriate referents is facilitated by phonological familiarity only for familiar referents but not for unfamiliar referents. Moreover, more extensive second-language learning experience characterized superior learners primarily in one word-learning condition: Where phonologically-unfamiliar novel words were paired with familiar referents. Conclusions Together, these findings indicate that phonological familiarity facilitates novel word learning only for familiar referents, and that experience with learning a second language may have a specific impact on novel vocabulary learning in adults.

  17. Effects of cross-language voice training on speech perception: whose familiar voices are more intelligible?

    Previous research has shown that familiarity with a talker's voice can improve linguistic processing (herein, "Familiar Talker Advantage"), but this benefit is constrained by the context in which the talker's voice is familiar. The current study examined how familiarity affects intelligibility by manipulating the type of talker information available to listeners. One group of listeners learned to identify bilingual talkers' voices from English words, where they learned language-specific talker information. A second group of listeners learned the same talkers from German words, and thus only learned language-independent talker information. After voice training, both groups of listeners completed a word recognition task with English words produced by both familiar and unfamiliar talkers. Results revealed that English-trained listeners perceived more phonemes correct for familiar than unfamiliar talkers, while German-trained listeners did not show improved intelligibility for familiar talkers. The absence of a processing advantage in speech intelligibility for the German-trained listeners demonstrates limitations on the Familiar Talker Advantage, which crucially depends on the language context in which the talkers' voices were learned; knowledge of how a talker produces linguistically relevant contrasts in a particular language is necessary to increase speech intelligibility for words produced by familiar talkers. © 2011 Acoustical Society of America

    The present research explored the effects of selective impairment to the entorhinal cortex on the processes of familiarity and recollection. To achieve this objective, the performance of patient MR, who has a selective impairment of the left entorhinal cortex, was compared to that of age and IQ-matched controls. Four experiments tested participants' recognition memory for familiar and unfamiliar faces and words. In all experiments, participants studied lists of items and then completed an old/new recognition test in which they also made remember/know/guess judgements. A fifth experiment tested participants' priming associated with the familiarity process. MR had intact performance in both face recognition experiments as well as having intact performance in pseudoword recognition. Crucially, however, in the familiar word experiment, whilst MR performed similarly to control participants in terms of recollection, she showed a marked impairment in familiarity. Furthermore, she also demonstrated a reversed conceptual priming effect. MR's impairment is both material-specific and selective for previously encountered but not new verbal items (pseudowords). These findings provide the first clear evidence that selective impairment of the entorhinal cortex impairs the familiarity process for familiar verbal material whilst leaving recollection intact. These results suggest the entorhinal cortex does not have attributes reflective of both recollection and familiarity as previously assumed, but rather supports context-free long-term familiarity-based recognition memory.

    Actually, the coffee is one of the most important exportation crops of the country. The utilization of obsolete or unsuitable processes, specifically related to the coffee drying, it can to damage the final quality of the product, besides to result in a low profitability of the coffee growing. In this work a mechanical drier (flex) was built, for the familiar coffee growing, being subsequently evaluated, to the drying of peeled cherry coffee, by the realization of two tests: one with heating of the air using vegetable coal and other combining the use of solar heater with vegetable coal. Basing on the results, it was possible to conclude that the drying of coffee in the mechanical drier Flex can be carried out using vegetable coal as fuel as well as associating the use of the vegetable coal with the solar collector, to save energy.

    Full Text Available We identified the important micro-relations that are perceived when attempting to recognize patterns in stimuli consisting of multiple dynamic objects. Skilled and less-skilled participants were presented with point light display sequences representing dynamic patterns in an invasion sport and were subsequently required to make familiarity based recognition judgments in three different conditions, each of which contained only a select number of features that were present at initial viewing. No differences in recognition accuracy were observed between skilled and less-skilled participants when just objects located in the periphery were presented. Yet, when presented with the relative motions of two centrally located attacking objects only, skilled participants were significantly more accurate than less-skilled participants and their recognition accuracy improved further when a target object was included against which these relative motions could be judged. Skilled participants can perceive and recognize global patterns on the basis of centrally located relational information.

    Behind genetics and Markov chains, there is an intrinsic algebraic structure. It is defined as a type of new algebra: as evolution algebra. This concept lies between algebras and dynamical systems. Algebraically, evolution algebras are non-associative Banach algebras; dynamically, they represent discrete dynamical systems. Evolution algebras have many connections with other mathematical fields including graph theory, group theory, stochastic processes, dynamical systems, knot theory, 3-manifolds, and the study of the Ihara-Selberg zeta function. In this volume the foundation of evolution algebra theory and applications in non-Mendelian genetics and Markov chains is developed, with pointers to some further research topics.

    Full Text Available No estudo aqui relatado identificaram-se os fatores que levam à formação do capital social familiar em empresas familiares. Para atingir o objetivo proposto, utilizou-se, como aporte teórico, a teoria do capital social e do capital social familiar. Para tanto, foi realizada uma pesquisa exploratória, do tipo survey, em 120 empreendimentos familiares. Aplicou-se questionário, sob a forma de entrevista, a todos os empresários. Os dados foram analisados por meio de análise fatorial. Os resultados foram apresentados em dois blocos: primeiro, a caracterização da amostra em relação ao perfil do respondente e ao perfil do empreendimento, bem como a apresentação da frequência de cada uma das assertivas; na segunda parte, foi feita a análise fatorial, após a qual foram identificados sete fatores relacionados com a formação do capital social familiar. São eles: diálogo colaborativo, rede familiar, infraestrutura moral, confiança, normas éticas, ideias próprias e canais de informação externos. O capital social familiar é solidificado por meio do diálogo colaborativo, a partir do qual é possível enraizar, na família e na empresa, as normas éticas, originando o que se chama de infraestrutura moral, quando a família e a empresa estão em sintonia interna e externa. Em um sentido contraditório, a ausência do diálogo colaborativo gera autoritarismo por parte dos dirigentes e membros da família, prevalecendo ideias próprias, as quais foram identificadas como fator contraditório à formação do capital social familiar.

    To increase the protein intake of older adults, protein enrichment of familiar foods and drinks might be an effective and attractive alternative for oral nutritional supplements (ONS). We performed a pilot study to test whether these products could help institutionalized elderly to reach a protein intake of 1.2 gram per kg body weight per day (g/kg/d). Intervention study with one treatment group (no control group). Dietary assessment was done before and at the end of a 10-day intervention. Two care facilities in Gelderland, the Netherlands: a residential care home and a rehabilitation center. 22 elderly subjects (13 women, 9 men; mean age 83.0±9.4 years). We used a variety of newly developed protein enriched regular foods and drinks, including bread, soups, fruit juices, and instant mashed potatoes. Dietary intake was assessed on two consecutive days before and at the end of the intervention, using food records filled out by research assistants. Energy and macronutrient intake was calculated using the 2013 Dutch food composition database. Changes in protein intake were evaluated using paired t-tests. Protein intake increased by 11.8 g/d (P=0.003); from 0.96 to 1.14 g/kg/d (P=0.002). This increase is comparable to protein provided by one standard portion of ONS. The intake of energy and other macronutrients did not change significantly. At the end of the intervention more elderly reached a protein intake level of 1.2 g/kg/d than before (9 vs 4). Protein intake significantly increased during breakfast (+3.7 g) and during the evening (+2.2 g). Including familiar protein enriched foods and drinks in the menu helped to meet protein recommendations in institutionalized elderly.

  6. Central oxytocin regulates social familiarity and scent marking behavior that involves amicable odor signals between male mice.

    The effect of oxytocin on social behavior and odor communication was investigated in male C57BL/6J mice. In three-male colonies, in visible burrow systems, icv oxytocin (OT) infusion before colony formation substantially increased huddling together over the initial 8 h of grouping, accompanied by decreased expression of a number of social approaches associated with conspecific aggression and defense. OT antagonist infusion had little impact on expression of social approaches but decreased time engaging in social components including huddle over the initial 8 h. These results demonstrate a linkage of social familiarity to OT availability in the brain. In a scent marking paradigm central infusion of OT reduced territorial marking towards male conspecifics, and this in turn reduced the scent marking of untreated stimulus males to OT-infused subjects. Infusion of an OT antagonist into stimulus mice who were confronted with OT-infused subjects prevented the reduction/suppression of scent marking that was normally seen following exposure of social odors released from OT-injected mice. Odor of pair-housed mice also induced a suppression of territorial scent marking in odor recipients, but OT antagonist administration into pair-housed mice blocked this suppressive effect of odor cue. These results indicate that central OT modulates release as well as detection of amicable signals facilitating/maintaining familiar relationships and suppressing territorial behavior between male mice. Overall, these findings suggest that OT plays a significant role in regulating social familiarity via changing qualities of conspecific odor cues.

    Lateralization of cognitive processes and motor functions has been demonstrated in a number of species, including humans, elephants, and cetaceans. For example, bottlenose dolphins (Tursiops truncatus) have exhibited preferential eye use during a variety of cognitive tasks. The present study investigated the possibility of visual lateralization in 12 belugas (Delphinapterus leucas) and six Pacific white-sided dolphins (Lagenorhynchus obliquidens) located at two separate marine mammal facilities. During free swim periods, the belugas and Pacific white-sided dolphins were presented a familiar human, an unfamiliar human, or no human during 10-15 min sessions. Session videos were coded for gaze duration, eye presentation at approach, and eye preference while viewing each stimulus. Although we did not find any clear group level lateralization, we found individual left eye lateralized preferences related to social stimuli for most belugas and some Pacific white-sided dolphins. Differences in gaze durations were also observed. The majority of individual belugas had longer gaze durations for unfamiliar rather than familiar stimuli. These results suggest that lateralization occurs during visual processing of human stimuli in belugas and Pacific white-sided dolphins and that these species can distinguish between familiar and unfamiliar humans.

Com isso, o campesinato tornou-se um tema de difícil articulação dentro do marxismo e do feminismo. Havia uma crença generalizada de que liberação das mulheres passaria necessariamente por sua independência financeira, fruto da inserção individual no mercado de trabalho. Como ‘encaixar’ aí as mulheres em regime de trabalho familiar? Elas não foram bem ‘encaixadas’, havendo com freqüência um ‘viés urbano’ perpassando as análises do trabalho feminino no campo. O surgimento de vários movimentos de mulheres agricultoras no Brasil colocou em cheque a visão corrente de ‘vítimas’ que se tinha sobre elas, na medida em que estão se impondo como ‘atoras’. Neste momento, porém, os movimentos feministas estão mais voltados para questões de reconhecimento, de identidade, que de redistribuição de renda, propriedades e, o que nos interessa mais, terra. Nosso objetivo neste trabalho é desvelar os preconceitos imbricados na análise do campesinato e trazer de volta questões sobre a condição econômica desigual das mulheres envolvidas na agricultura familiar, cujo acesso à terra se faz quase unicamente pelo casamento. O direito de tomar decisões sobre a própria vida pode ser desvinculado da obtenção de um salário individual, mas não do acesso a uma renda própria.

  17. The Influence of Kinship on Familiar Natal Migrant Rhesus Macaques (Macaca mulatta)

    In most primate species, females remain in the natal group with kin while males disperse away from kin around the time of puberty. Philopatric females bias their social behavior toward familiar maternal and paternal kin in several species, but little is known about kin bias in the dispersing sex. Male dispersal is likely to be costly because males encounter an increased risk of predation and death, which might be reduced by dispersing together with kin and/or familiar males (individuals that were born and grew up in same natal group) or into a group containing kin and/or familiar males. Here we studied the influence of kinship on familiar natal migrant rhesus macaques (Macaca mulatta) on Cayo Santiago, Puerto Rico, by combining demographic, behavioral, and genetic data. Our data suggest that kinship influences spatial proximity between recent natal immigrants and males familiar to them. Immigrants were significantly nearer to more closely related familiar males than to more distantly related individuals. Within a familiar subgroup, natal migrants were significantly closer to maternal kin, followed by paternal kin, then non-kin, and finally to males related via both the maternal and paternal line. Spatial proximity between natal immigrants and familiar males did not decrease over time in the new group, suggesting that there is no decline in associations between these individuals within the first months of immigration. Overall, our results might indicate that kinship is important for the dispersing sex, at least during natal dispersal when kin are still available. PMID:24850977

    Full Text Available The effects of both symmetry (perceptual factor and familiarity (cognitive factor on facial attractiveness were investigated. From the photographs of original slightly asymmetric faces, symmetric left-left (LL and right-right (RR versions were generated. Familiarity was induced in the learning block using the repetitive presentation of original faces. In the test block participants rated the attractiveness of original, previously seen (familiar faces, original, not previously seen faces, and both LL and RR versions of all faces. The analysis of variance showed main effects of symmetry. Post hoc tests revealed that asymmetric original faces were rated as more attractive than both LL and RR symmetric versions. Familiarity doesn’t have a significant main effect, but the symmetry-familiarity interaction was obtained. Additional post hoc tests indicated that facial attractiveness is positively associated with natural slight asymmetry rather than with perfect symmetry. Also, unfamiliar LL symmetric versions were rated as more attractive than familiar LL versions, whereas familiar RR versions were rated as more attractive than RR unfamiliar faces. These results suggested that symmetry (perceptual factor and familiarity (cognitive or memorial factor play differential roles in facial attractiveness, and indicate a relatively stronger effect of the perceptual compared to the cognitive factor.

    Full Text Available El objetivo fue conocer experiencias de familias de personas con trastorno mental en municipios de pequeño porte, en el Alto Sertão Paraibano, Brasil. Investigación exploratoria, cualitativa, llevada a cabo con 14 parientes. La recolección de datos se llevó a cabo en febrero y marzo de 2013, utilizando la técnica de historia oral de vida, basada en guión semiestructurado de preguntas. Para interpretación de los datos, se utilizó el análisis de contenido temático. Los resultados señalaron expresivo sufrimiento y dificultades de la familia en la atención a la persona con trastorno mental, ya que se sentían solos, a menudo sin apoyo familiar, político y profesional. La sobrecarga de estas familias fue destacada por enfermedades crónicas, uso de medicamentos y separación matrimonial. La mejora de los servicios de salud existentes y la formulación de políticas municipales podrán promover mejor calidad de vida a estas personas.

    Full Text Available Los agentes de socialización son los responsables de la transmisión de las normas, valores y modelos de comportamiento y, dentro de ellos, la familia es el más importante, no sólo porque es el primero en actuar, sino porque se constituye en el nexo entre el individuo y la sociedad. Es la familia la que socializa al niño permi- tiéndole interiorizar los elementos básicos de la cultura y desarrollar las bases de su personalidad. Toda familia socializa al niño de acuerdo a su particular modo de vida, el cual está influenciado por la realidad social, económica e histórica de la sociedad a la que perte- nece. Se han delineado tres estilos de interacción entre padres e hijos que pueden estar relacionados con el desarrollo de la conducta prosocial: dictadores, autoritarios y per- misivos.

    Full Text Available Desde una perspectiva sociológica es de gran interés el cambio que ha experimentado la familia española en los últimos años, en particular cómo los nuevos roles femeninos han contribuido a su reorganización y redifinición. Una consecuencia es que el tradicional modelo de autoridad familiar, jerárquicamente organizado alrededor de la figura paterna, está perdiendo legitimidad y siendo gradualmente suplantado por un concepto de igualdad basado en la redistribución de los roles de género. Aunque la familia continúa desempeñando un papel fundamental en la organización social, la cohabitación está incrementando su importancia y proyectando sobre la familia muchos de los atributos que están asociados al nuevo modelo, como la idea de familia como opción más que como un destino irrenunciable de los seres humanos. Otras implicaciones están relacionadas con la menor valoración de los apoyos religiosos e institucionales, que están perdiendo fuerza a favor de otros valores como la comunicación y el afecto.

    Full Text Available Objetive: to estimate the prevalence of alcohol use in youth from a private university in Cali – Colombia, and its relation with familiar and social factors. Methodology: secondary source analysis, from a prevalence study. 548 college youth participated, selected through a randomized stratified sampling. Results: the prevalence of alcohol use in life was 96%, last year was 89% and last month was 67%. Actual alcohol use and age of first use were similar between men and women. Age of first use was lower in youth with family members that get drunk frequently, and actual use of alcohol was higher in those with friends that get drunk frequently. Risky or hazardous alcohol use was higher in youth with family members and friends that get drunk frequently. Discussion: the results from this study show the influence of alcohol use in family members and friends in youth’s alcohol drinking; pointing out that this practice is socially legitimated, being common in youth’s context, facilitating its appearance and maintenance.

    Quienes se han dedicado a la práctica de la enfermería, han tenido que ver con la familia en alguna forma, bien como sujeto central de su acción o como sujeto secundario. El enfoque holístico con el que se aborda el quehacer profesional explica suficientemente este acercamiento familiar.  Aunque en los planes de formación de los profesionales de enfermería, existe desequilibrio en el sentido de poseer una mayoría de elementos conceptuales relacionados con el área biológica, se debe aceptar que el contenido en aspectos comportamentales y sociales en general, no se ha descuidado. En este orden, se encuentran asignaturas como: psicología general, evolutiva y social. Antropología, sociología y problemas sociales, para mencionar algunas, que en general dan un sustento teórico suficientemente amplio, para comprender y orientar al sujeto de sus acciones: el ser humano y el contexto en el que se desenvuelve.

Para ello se administró la escala CD-RISC a una muestra de 111 cuidadores. En función de las puntuaciones obtenidas, se distinguieron dos grupos: alta vs. moderada o baja resiliencia. Se analizaron las diferencias entre ambos grupos en las diversas variables que afectan al estrés del cuidador. Aunque hubo diferencias en el estado cognitivo del receptor de cuidado, las mayores diferencias se obtuvieron en las denominadas variables mediadoras, observando en los cuidadores con alta resiliencia mayores puntuaciones en: satisfacción con el apoyo social recibido, autoeficacia para controlar los pensamientos negativos, autoestima, autocuidado y extraversión; y siendo estas diferencias estadísticamente significativas. Asimismo los cuidadores altamente resilientes tendieron a manifestar una menor preocupación por los problemas del mayor, y presentaron menores niveles de sintomatología depresiva y ansiosa. Este estudio pone de manifiesto la importancia de la resiliencia como factor de protección en el ámbito del estrés crónico, incorporando aspectos positivos de la adaptación a los modelos teóricos de cuidado, los cuales tradicionalmente se han venido centrando en el desarrollo de sintomatología.

  20. The Art of Reflection: Turning the Strange into the Familiar.

    There are a great many useful articles on the dynamics and pragmatics of reflecting teams but few articles address what constitutes a good or inept reflection and why. I provide a conceptual model for thinking about what a good reflection does, distinguishing it from a nice reflection. With some further refinements in place, I then illustrate how reflections can be part of any relationship, not just clinical ones. We have opportunities to make them and to recognize when others make them to us. By using examples from my personal life-as a grandmother, daughter, radio listener, cancer survivor, and client-I attempt to ease the personal/professional binary, a project of mine for the last 35 years. In the second part of the article, I address how writing can serve reflection. Although best offered at the moment one is called for, it is never too late for a reflection. Writing allows people to offer reflections after the fact to those who have shared their stories. Sometimes, it is to ourselves we offer those reflections, when the reflector has long since dropped the thread of obligation or interest. I provide an example of working with iconic imagery to unpack meaning so that reflection can eventually take place, allowing integration to proceed, facilitating the strange becoming the familiar. © 2015 Family Process Institute.

  1. Student Teachers' Approaches to Teaching Biological Evolution

    Evolution is fundamental to biology and scientific literacy, but teaching high school evolution is often difficult. Evolution teachers face several challenges including limited content knowledge, personal conflicts with evolution, expectations of resistance, concerns about students' conflicts with religion, and curricular constraints. Evolution teaching can be particularly challenging for student teachers who are just beginning to gain pedagogical knowledge and pedagogical content knowledge related to evolution teaching and who seek approval from university supervisors and cooperating teachers. Science teacher educators need to know how to best support student teachers as they broach the sometimes daunting task of teaching evolution within student teaching placements. This multiple case study report documents how three student teachers approached evolution instruction and what influenced their approaches. Data sources included student teacher interviews, field note observations for 4-5 days of evolution instruction, and evolution instructional artifacts. Data were analyzed using grounded theory approaches to develop individual cases and a cross-case analysis. Seven influences (state exams and standards, cooperating teacher, ideas about teaching and learning, concerns about evolution controversy, personal commitment to evolution, knowledge and preparation for teaching evolution, and own evolution learning experiences) were identified and compared across cases. Implications for science teacher preparation and future research are provided.

    Personally familiar faces are processed more robustly and efficiently than unfamiliar faces. The human face processing system comprises a core system that analyzes the visual appearance of faces and an extended system for the retrieval of person-knowledge and other nonvisual information. We applied multivariate pattern analysis to fMRI data to investigate aspects of familiarity that are shared by all familiar identities and information that distinguishes specific face identities from each other. Both identity-independent familiarity information and face identity could be decoded in an overlapping set of areas in the core and extended systems. Representational similarity analysis revealed a clear distinction between the two systems and a subdivision of the core system into ventral, dorsal and anterior components. This study provides evidence that activity in the extended system carries information about both individual identities and personal familiarity, while clarifying and extending the organization of the core system for face perception.

    Full Text Available Stress or arousal responses to novel social contexts ease off when individuals get familiar with the social context. In the present study we investigated whether oxytocin is involved in this process of familiarization-habituation, as oxytocin is known to increase trust and decrease anxiety. Fifty-nine healthy female subjects took part in the same experimental procedure in two sessions separated by four weeks. In the first (novelty session state trust scores were significantly positively correlated with salivary oxytocin levels, while in the second (familiarity session state trust scores were significantly negatively correlated with salivary oxytocin levels. In a path model, oxytocin was associated with increased trust in the novelty session and trust was associated with decreased oxytocin levels in the familiarity session. The results are consistent with the idea that oxytocin decreases stress-to-novelty responses by promoting familiarization to novel social contexts.

Understanding the health workers’ level of experience of mental illness and their likely behavioural responses towards people with psychiatric illness, therefore, should be a good baseline to understanding their likely reactions towards admitting such patients within a general hospital setting. The study, which used a pre-tested and adapted attribution questionnaire, was pro­spective and cross-sectional. Randomly selected health workers in Aminu Kano Teaching Hospital had their level of familiarity and attributions towards psychiatric patients assessed. The respondents showed a high level of experience with mental illness, with more than 3 in 5 of them having watched movies on mental illness before. More than half of them held positive (favorable attributions towards persons with mental illness on nine of the ten assessed attribution factors. Almost all held negative (unfavourable opinion towards intimate relationships with such persons. Attribution factors, “Responsibility, “Anger”, “Dangerousness”, “Fear” and “Segregation” were significantly related to the respondents’ level of education (P less than 0.05. Marital status of the respondents related significantly to “Pity” and “Avoidance” factors (P less than 0.05. Having watched movies on mental illness significantly related to “Responsibility” and “Fear” factors (P less than 0.05. Programs designed to improve the health workers mental health literacy, and increased positive professional contacts with mentally ill persons on treatment, would further enhance their perceived positive attributions towards them.

Por isso, vários governos orientaram para lá programas de desenvolvimento rural. Mas esses esforços não produziram bons resultados. Este artigo analisa as relações entre programas públicos e agricultura familiar, fazendo um balanço dos métodos e resultados das últimas três décadas. Conclui pela necessidade de incorporar as especificidades de história, ambientes e sociedade aos programas, que deveriam partir das experiências das organizações da região e se ajustar às ações e à cultura desses agricultores.The agrarian conditions and the low relative levels of the socioeconomic indicators cause the area of the "High Jequitinhonha Valley", in the northeast of the State of Minas Gerais, to be considered one of the most complex areas of Brazil. For this reason several governanmental administrations have recommended rural development programs. Most of these efforts, however, have not produced adequate results. This article analyzes the relationships between public programs and family farming, making a survey of the methods and results of the last three decades. It concludes that there is a need to incorporate the specificities of history, environment and culture into the rural programs. It is suggested that the programs take into consideration the experience accumulated by the regional organizations and be adjusted to the interest and culture of the local family producers.

    BACKGROUND: Biologic patent expiration, accelerated approval pathways, and business interests of third party payers and the biopharmaceutical industry are driving the development of biosimilars to treat immune-mediated disorders like psoriasis. No studies have investigated dermatologists' familiarity and perspectives of biosimilars. OBJECTIVES: To assess: (1) dermatologists' familiarity with biosimilars and interchangeability and (2) their perspectives toward biosimilar properties, including interchangeability, indication extrapolation, and immunogenicity risk. METHODS: For this prospective survey study, we distributed electronic and paper questionnaires to dermatologists from selected societies and attendees at the 73rd annual American Academy of Dermatology meeting between March 20, 2015 and May 30, 2015. Primary outcome was dermatologists' familiarity with biosimilars. Secondary aims included dermatologists' confidence in biosimilar efficacy and safety, familiarity concerning the concept of interchangeability and perspectives regarding indication extrapolation, interchangeability, and immunogenicity risk. RESULTS: Of the 116 total dermatologists who completed the questionnaire, 73 (62.9%) were slightly to very unfamiliar with biosimilars. On a 5-point Likert scale, dermatologists were somewhat to very concerned with the practice of interchangeability (3.4±1.1) and slightly uncomfortable to fairly comfortable in prescribing biosimilars for an extrapolated indication (3.3±1.0). CONCLSUIONS: Our survey identified that the majority of dermatologists were unfamiliar with biosimilars. Dermatologists were consistently concerned regarding safety issues surrounding the practice of interchangeability without provider knowledge. J Drugs Dermatol. 2017;16(4):336-343..

  14. Are there ergodic limits to evolution? Ergodic exploration of genome space and convergence.

    McLeish, Tom C B

    2015-12-06

    We examine the analogy between evolutionary dynamics and statistical mechanics to include the fundamental question of ergodicity-the representative exploration of the space of possible states (in the case of evolution this is genome space). Several properties of evolutionary dynamics are identified that allow a generalization of the ergodic dynamics, familiar in dynamical systems theory, to evolution. Two classes of evolved biological structure then arise, differentiated by the qualitative duration of their evolutionary time scales. The first class has an ergodicity time scale (the time required for representative genome exploration) longer than available evolutionary time, and has incompletely explored the genotypic and phenotypic space of its possibilities. This case generates no expectation of convergence to an optimal phenotype or possibility of its prediction. The second, more interesting, class exhibits an evolutionary form of ergodicity-essentially all of the structural space within the constraints of slower evolutionary variables have been sampled; the ergodicity time scale for the system evolution is less than the evolutionary time. In this case, some convergence towards similar optima may be expected for equivalent systems in different species where both possess ergodic evolutionary dynamics. When the fitness maximum is set by physical, rather than co-evolved, constraints, it is additionally possible to make predictions of some properties of the evolved structures and systems. We propose four structures that emerge from evolution within genotypes whose fitness is induced from their phenotypes. Together, these result in an exponential speeding up of evolution, when compared with complete exploration of genomic space. We illustrate a possible case of application and a prediction of convergence together with attaining a physical fitness optimum in the case of invertebrate compound eye resolution.

  15. Computational evolution: taking liberties.

    Science.gov (United States)

    Correia, Luís

    2010-09-01

    Evolution has, for a long time, inspired computer scientists to produce computer models mimicking its behavior. Evolutionary algorithm (EA) is one of the areas where this approach has flourished. EAs have been used to model and study evolution, but they have been especially developed for their aptitude as optimization tools for engineering. Developed models are quite simple in comparison with their natural sources of inspiration. However, since EAs run on computers, we have the freedom, especially in optimization models, to test approaches both realistic and outright speculative, from the biological point of view. In this article, we discuss different common evolutionary algorithm models, and then present some alternatives of interest. These include biologically inspired models, such as co-evolution and, in particular, symbiogenetics and outright artificial operators and representations. In each case, the advantages of the modifications to the standard model are identified. The other area of computational evolution, which has allowed us to study basic principles of evolution and ecology dynamics, is the development of artificial life platforms for open-ended evolution of artificial organisms. With these platforms, biologists can test theories by directly manipulating individuals and operators, observing the resulting effects in a realistic way. An overview of the most prominent of such environments is also presented. If instead of artificial platforms we use the real world for evolving artificial life, then we are dealing with evolutionary robotics (ERs). A brief description of this area is presented, analyzing its relations to biology. Finally, we present the conclusions and identify future research avenues in the frontier of computation and biology. Hopefully, this will help to draw the attention of more biologists and computer scientists to the benefits of such interdisciplinary research.

    Observing other people's actions facilitates the observer's motor system as compared with observing the same individuals at rest. This motor activation is thought to result from mirror-like activity in fronto-parietal areas, which enhances the excitability of the primary motor cortex via cortico-cortical pathways. Although covert motor activation in response to observed actions has been widely investigated between conspecifics, how humans cope with other species' actions has received less attention. For example, it remains unclear whether the human motor system is activated by observing other species' actions, and whether prior familiarity with the non-conspecific agent modulates this activation. Here, we combined single-pulse transcranial magnetic stimulation and motor-evoked potential recording to explore the impact of familiarity on motor activation during the observation of non-conspecific actions. Videos displaying actions performed either by a conspecific (human) or by a non-conspecific (dog) were shown to individuals who had prior familiarity or no familiarity at all with the non-conspecific agent. We found that, whereas individuals with long-lasting familiarity showed similar levels of motor activation for human and canine actions, individuals who had no familiarity showed higher motor activation for human than for canine actions. These findings suggest that the human motor system is flexible enough to resonate with other species, and that familiarity plays a key role in tuning this ability. © 2015 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    Full Text Available The ability to recognize an individual from their voice is a widespread ability with a long evolutionary history. Yet, the perceptual representation of familiar voices is ill-defined. In two experiments, we explored the neuropsychological processes involved in the perception of voice identity. We specifically explored the hypothesis that familiar voices (trained-to-familiar (Experiment 1, and famous voices (Experiment 2 are represented as a whole complex pattern, well approximated by the average of multiple utterances produced by a single speaker. In experiment 1, participants learned three voices over several sessions, and performed a three-alternative forced-choice identification task on original voice samples and several “speaker averages,” created by morphing across varying numbers of different vowels (e.g., [a] and [i] produced by the same speaker. In experiment 2, the same participants performed the same task on voice samples produced by familiar speakers. The two experiments showed that for famous voices, but not for trained-to-familiar voices, identification performance increased and response times decreased as a function of the number of utterances in the averages. This study sheds light on the perceptual representation of familiar voices, and demonstrates the power of average in recognizing familiar voices. The speaker average captures the unique characteristics of a speaker, and thus retains the information essential for recognition; it acts as a prototype of the speaker.

    Physical therapists' familiarity, perceptions, and beliefs about health services utilization and health seeking behaviour have not been previously assessed. The purposes of this study were to identify physical therapists' characteristics related to familiarity of health services utilization and health seeking behaviour, and to assess what health seeking behaviour factors providers felt were related to health services utilization. We administered a survey based on the Andersen behavioural model of health services utilization to physical therapists using social media campaigns and email between March and June of 2017. In addition to descriptive statistics, we performed binomial logistic regression analysis. We asked respondents to rate familiarity with health services utilization and health seeking behaviour and collected additional characteristic variables. Physical therapists are more familiar with health services utilization than health seeking behaviour. Those who are familiar with either construct tend to be those who assess for health services utilization, use health services utilization for a prognosis, and believe that health seeking behaviour is measurable. Physical therapists rated need and enabling factors as having more influence on health services utilization than predisposing and health belief factors. Physical therapists are generally familiar with health services utilization and health seeking behaviour; however, there appears to be a disconnect between what is familiar, what is perceived to be important, and what can be assessed for both health services utilization and health seeking behaviour.

  1. The use of cue familiarity during retrieval failure is affected by past versus future orientation.

    Science.gov (United States)

    Cleary, Anne M

    2015-01-01

    Cue familiarity that is brought on by cue resemblance to memory representations is useful for judging the likelihood of a past occurrence with an item that fails to actually be retrieved from memory. The present study examined the extent to which this type of resemblance-based cue familiarity is used in future-oriented judgments made during retrieval failure. Cue familiarity was manipulated using a previously-established method of creating differing degrees of feature overlap between the cue and studied items in memory, and the primary interest was in how these varying degrees of cue familiarity would influence future-oriented feeling-of-knowing (FOK) judgments given in instances of cued recall failure. The present results suggest that participants do use increases in resemblance-based cue familiarity to infer an increased likelihood of future recognition of an unretrieved target, but not to the extent that they use it to infer an increased likelihood of past experience with an unretrieved target. During retrieval failure, the increase in future-oriented FOK judgments with increasing cue familiarity was significantly less than the increase in past-oriented recognition judgments with increasing cue familiarity.

    Personally familiar people are likely to be represented more richly in episodic, emotional, and behavioral contexts than famous people, who are usually represented predominantly in semantic context. To reveal cortical mechanisms supporting this differential person representation, we compared cortical activation during name recognition tasks between personally familiar and famous names, using an event-related functional magnetic resonance imaging (fMRI). Normal subjects performed familiar- or unfamiliar-name detection tasks during visual presentation of personally familiar (Personal), famous (Famous), and unfamiliar (Unfamiliar) names. The bilateral temporal poles and anterolateral temporal cortices, as well as the left temporoparietal junction, were activated in the contrasts Personal-Unfamiliar and Famous-Unfamiliar to a similar extent. The bilateral occipitotemporoparietal junctions, precuneus, and posterior cingulate cortex showed activation in the contrasts Personal-Unfamiliar and Personal-Famous. Together with previous findings, differential activation in the occipitotemporoparietal junction, precuneus, and posterior cingulate cortex between personally familiar and famous names is considered to reflect differential person representation. The similar extent of activation for personally familiar and famous names in the temporal pole and anterolateral temporal cortex is consistent with the associative role of the anterior temporal cortex in person identification, which has been conceptualized as a person identity node in many models of person identification. The left temporoparietal junction was considered to process familiar written names. The results illustrated the neural correlates of the person representation as a network of discrete regions in the bilateral posterior cortices, with the anterior temporal cortices having a unique associative role.

    2013-08-01

    In many group-living animals, within-group associations are determined by familiarity, i.e. familiar individuals, independent of genetic relatedness, preferentially associate with each other. The ultimate causes of this behaviour are poorly understood and rigorous documentation of its adaptive significance is scarce. Limited attention theory states that focusing on a given task has interrelated cognitive, behavioural and physiological costs with respect to the attention paid to other tasks. In multiple signal environments attention has thus to be shared among signals. Assuming that familiar neighbours require less attention than unfamiliar ones, associating with familiar individuals should increase the efficiency in other tasks and ultimately increase fitness. We tested this prediction in adult females of the group-living, plant-inhabiting predatory mite Phytoseiulus persimilis. We evaluated the influence of social familiarity on within-group association behaviour, activity, predation and reproduction. In mixed groups (familiar and unfamiliar), familiar predator females preferentially associated with each other. In pure groups (either familiar or unfamiliar), familiar predator females produced more eggs than unfamiliar females at similar predation rates. Higher egg production was correlated with lower activity levels, indicating decreased restlessness. In light of limited attention theory, we argue that the ability to discriminate between familiar and unfamiliar individuals and preferential association with familiar individuals confers a selective advantage because familiar social environments are cognitively and physiologically less taxing than unfamiliar social environments.

    Highlights: ► The paper describes the recent evolution of the MDSplus data system. ► It presents a Use Case to explain MDSplus expressions. ► It presents the features recently developed. ► It presents the features under development. - Abstract: The MDSplus data system has been in operation on several fusion machines since 1991 and it is currently in use at over 30 sites spread over 5 continents. A consequence is the extensive feedback provided by the MDSplus user community for bug fixes and improvements and therefore the evolution of MDSplus is keeping pace with the evolution in data acquisition and management techniques. In particular, the recent evolution of MDSplus has been driven by the change in the paradigm for data acquisition in long lasting plasma discharges, where a sustained data stream is transferred from the acquisition devices into the database. Several new features are currently available or are being implemented in MDSplus. The features already implemented include a comprehensive Object-Oriented interface to the system, the python support for data acquisition devices and the full integration in EPICS. Work is in progress for the integration of multiple protocols and security systems in remote data access, a new high level data view layer and a new version of the jScope tool for online visualization and the optimized visualization of very large signals.

    2015-03-01

    In a social eating context, people tend to model the food intake of their dining companions. In general, people tend to eat more when their dining companion eats more and less when their eating companion eats less. In the present paper we investigate 1) whether familiarity of dining partners affects modelling and 2) whether modelling is affected by whether familiar partners consume the same versus different foods. In both studies, female dyads completed a task together whilst having access to high energy dense snack foods. Modelling was observed regardless of the familiarity of the dining partners and food types consumed. These findings confirm that social modelling of food intake is a robust phenomenon that occurs even among familiar dining partners and when partners are consuming different types of snack food.

    2013-01-01

    Full Text Available The main objective of this paper is to examine the impact of familiar music on self-consciousness (SC in patients with Alzheimer’s disease (AD. For this purpose, two AD groups of 20 patients matched by age, educational level, gender, illness duration, and cognitive state were assessed using an SC questionnaire before and after music intervention. The SC questionnaire measured several aspects: personal identity, anosognosia, affective state, body representation, prospective memory, introspection and moral judgments. One AD group received familiar music stimulation and another AD group unfamiliar music stimulation over three months. The AD patients who received a familiar music intervention showed a stabilization or improvement in aspects of SC. By contrast, control AD group showed a deterioration of most of the SC aspects after unfamiliar music stimulation, except the SC aspects of body representation and affective state. Familiar music stimulation could be considered as an enhancer of SC in patients with Alzheimer’s disease.

    Participants heard music snippets of varying melodic and instrumental familiarity paired with animal-name titles. They then recalled the target when given either the melody or the title as a cue, or they gave name feeling-of-knowing (FOK) ratings. In general, recall for titles was better than it was for melodies, and recall was enhanced with increasing melodic familiarity of both the cues and the targets. Accuracy of FOK ratings, but not magnitude, also increased with increasing familiarity. Although similar ratings were given after melody and title cues, accuracy was better with title cues. Finally, knowledge of the real titles of the familiar music enhanced recall but had, by and large, no effect on the FOK ratings. Copyright 2004 APA, all rights reserved

    This experiment examined the effects of women's relationship motivation, partner familiarity, and alcohol consumption on sexual decision making. Women completed an individual difference measure of relationship motivation and then were randomly assigned to partner familiarity condition (low, high) and to alcohol consumption condition (high dose, low dose, no alcohol, placebo). Then women read and projected themselves into a scenario of a sexual encounter. Relationship motivation and partner familiarity interacted with intoxication to influence primary appraisals of relationship potential. Participants' primary and secondary relationship appraisals mediated the effects of women's relationship motivation, partner familiarity, and intoxication on condom negotiation, sexual decision abdication, and unprotected sex intentions. These findings support a cognitive mediation model of women's sexual decision making and identify how individual and situational factors interact to shape alcohol's influences on cognitive appraisals that lead to risky sexual decisions. This knowledge can inform empirically based risky sex interventions.

    Full Text Available The thought evolution is studied by historical reconstruction method that is based on the propositions of the theory of culturalhistorical determination of the psyche development, and the data of the morphological analysis and child development, and the conception of the psyche neuroontogenesis. The grounds for advisability of protothinking are presented. The protothinking is understood as the use of objective thought in cases of awareness absence. It is shown that protothinking is a form of transition from animal thinking to human speech. The particular attention is paid to the process of the word producing and thought generation in that process. The conditions of word producing as cooccurring acoustic pattern served for though expression are discussed. It is emphasized that a word is produced by a particular person. The historical development of the language and the specificity of this development are pointed out

    1975-03-01

    Rubenstein's failure to find evidence for the previously suggested lack of concordance between visual and manipulative responses to novel and familiar stimuli in 6-month-old infants is discussed. It is shown that a lack of concordance is not specific to the use of 1 measure of manipulative behavior, and other possible explanations for the discrepancy in findings are examined. A 2-stage development of responsiveness to familiarity-novelty in infancy remains the most plausible account.

  15. Familiarity Speeds Up Visual Short-term Memory Consolidation: Electrophysiological Evidence from Contralateral Delay Activities.

    To test how preexisting long-term memory influences visual STM, this study takes advantage of individual differences in participants' prior familiarity with Pokémon characters and uses an ERP component, the contralateral delay activity (CDA), to assess whether observers' prior stimulus familiarity affects STM consolidation and storage capacity. In two change detection experiments, consolidation speed, as indexed by CDA fractional area latency and/or early-window (500-800 msec) amplitude, was significantly associated with individual differences in Pokémon familiarity. In contrast, the number of remembered Pokémon stimuli, as indexed by Cowan's K and late-window (1500-2000 msec) CDA amplitude, was significantly associated with individual differences in Pokémon familiarity when STM consolidation was incomplete because of a short presentation of Pokémon stimuli (500 msec, Experiment 2), but not when STM consolidation was allowed to complete given sufficient encoding time (1000 msec, Experiment 1). Similar findings were obtained in between-group analyses when participants were separated into high-familiarity and low-familiarity groups based on their Pokémon familiarity ratings. Together, these results suggest that stimulus familiarity, as a proxy for the strength of preexisting long-term memory, primarily speeds up STM consolidation, which may subsequently lead to an increase in the number of remembered stimuli if consolidation is incomplete. These findings thus highlight the importance of research assessing how effects on representations (e.g., STM capacity) are in general related to (or even caused by) effects on processes (e.g., STM consolidation) in cognition.

  17. The Role of Familiarity for Representations in Norm-Based Face Space.

    2016-01-01

    According to the norm-based version of the multidimensional face space model (nMDFS, Valentine, 1991), any given face and its corresponding anti-face (which deviates from the norm in exactly opposite direction as the original face) should be equidistant to a hypothetical prototype face (norm), such that by definition face and anti-face should bear the same level of perceived typicality. However, it has been argued that familiarity affects perceived typicality and that representations of familiar faces are qualitatively different (e.g., more robust and image-independent) from those for unfamiliar faces. Here we investigated the role of face familiarity for rated typicality, using two frequently used operationalisations of typicality (deviation-based: DEV), and distinctiveness (face in the crowd: FITC) for faces of celebrities and their corresponding anti-faces. We further assessed attractiveness, likeability and trustworthiness ratings of the stimuli, which are potentially related to typicality. For unfamiliar faces and their corresponding anti-faces, in line with the predictions of the nMDFS, our results demonstrate comparable levels of perceived typicality (DEV). In contrast, familiar faces were perceived much less typical than their anti-faces. Furthermore, familiar faces were rated higher than their anti-faces in distinctiveness, attractiveness, likability and trustworthiness. These findings suggest that familiarity strongly affects the distribution of facial representations in norm-based face space. Overall, our study suggests (1) that familiarity needs to be considered in studies of mental representations of faces, and (2) that familiarity, general distance-to-norm and more specific vector directions in face space make different and interactive contributions to different types of facial evaluations.

  19. Familiarity Detection is an Intrinsic Property of Cortical Microcircuits with Bidirectional Synaptic Plasticity

    Science.gov (United States)

    2017-01-01

    Abstract Humans instantly recognize a previously seen face as “familiar.” To deepen our understanding of familiarity-novelty detection, we simulated biologically plausible neural network models of generic cortical microcircuits consisting of spiking neurons with random recurrent synaptic connections. NMDA receptor (NMDAR)-dependent synaptic plasticity was implemented to allow for unsupervised learning and bidirectional modifications. Network spiking activity evoked by sensory inputs consisting of face images altered synaptic efficacy, which resulted in the network responding more strongly to a previously seen face than a novel face. Network size determined how many faces could be accurately recognized as familiar. When the simulated model became sufficiently complex in structure, multiple familiarity traces could be retained in the same network by forming partially-overlapping subnetworks that differ slightly from each other, thereby resulting in a high storage capacity. Fisher’s discriminant analysis was applied to identify critical neurons whose spiking activity predicted familiar input patterns. Intriguingly, as sensory exposure was prolonged, the selected critical neurons tended to appear at deeper layers of the network model, suggesting recruitment of additional circuits in the network for incremental information storage. We conclude that generic cortical microcircuits with bidirectional synaptic plasticity have an intrinsic ability to detect familiar inputs. This ability does not require a specialized wiring diagram or supervision and can therefore be expected to emerge naturally in developing cortical circuits. PMID:28534043

  20. Familiar Person Recognition: Is Autonoetic Consciousness More Likely to Accompany Face Recognition Than Voice Recognition?

    Science.gov (United States)

    Barsics, Catherine; Brédart, Serge

    2010-11-01

    Autonoetic consciousness is a fundamental property of human memory, enabling us to experience mental time travel, to recollect past events with a feeling of self-involvement, and to project ourselves in the future. Autonoetic consciousness is a characteristic of episodic memory. By contrast, awareness of the past associated with a mere feeling of familiarity or knowing relies on noetic consciousness, depending on semantic memory integrity. Present research was aimed at evaluating whether conscious recollection of episodic memories is more likely to occur following the recognition of a familiar face than following the recognition of a familiar voice. Recall of semantic information (biographical information) was also assessed. Previous studies that investigated the recall of biographical information following person recognition used faces and voices of famous people as stimuli. In this study, the participants were presented with personally familiar people's voices and faces, thus avoiding the presence of identity cues in the spoken extracts and allowing a stricter control of frequency exposure with both types of stimuli (voices and faces). In the present study, the rate of retrieved episodic memories, associated with autonoetic awareness, was significantly higher from familiar faces than familiar voices even though the level of overall recognition was similar for both these stimuli domains. The same pattern was observed regarding semantic information retrieval. These results and their implications for current Interactive Activation and Competition person recognition models are discussed.

  1. Novelty vs. familiarity principles in preference decisions: Task-context of past experience matters

    2011-03-01

    Full Text Available Our preferences are shaped by past experience in many ways, but a systematic understanding of the factors is yet to be achieved. For example, studies of the mere exposure effect show that experience with an item leads to increased liking (familiarity preference, but the exact opposite tendency is found in other studies utilizing dishabituation (novelty preference. Recently, it has been found that image category affects whether familiarity or novelty preference emerges from repeated stimulus exposure (Park, Shimojo, and Shimojo, PNAS 2010. Faces elicited familiarity preference, but natural scenes elicited novelty preference. In their task, preference judgments were made throughout all exposures, raising the question of whether the task-context during exposure was involved. We adapt their paradigm, testing if passive exposure or objective judgment task-contexts lead to different results. Results showed that after passive viewing, familiar faces were preferred, but no preference bias in either direction was found with natural scenes, or with geometric figures (control. After exposure during the objective judgment task, familiar faces were preferred, novel natural scenes were preferred, and no preference bias was found with geometric figures. The overall results replicate the segregation of preference biases across object categories and suggest that the preference for familiar faces and novel natural scenes are modulated by task-context memory at different processing levels or selection involvement. Possible underlying mechanisms of the two types of preferences are discussed.

    Source memory tests typically require subjects to make decisions about the context in which an item was encoded and are thought to depend on recollection of details from the study episode. Although it is generally believed that familiarity does not contribute to source memory, recent behavioral studies have suggested that familiarity may also support source recognition when item and source information are integrated, or "unitized," during study (Diana, Yonelinas, and Ranganath, 2008). However, an alternative explanation of these behavioral findings is that unitization affects the manner in which recollection contributes to performance, rather than increasing familiarity-based source memory. To discriminate between these possibilities, we conducted an event-related potential (ERP) study testing the hypothesis that unitization increases the contribution of familiarity to source recognition. Participants studied associations between words and background colors using tasks that either encouraged or discouraged unitization. ERPs were recorded during a source memory test for background color. The results revealed two distinct neural correlates of source recognition: a frontally distributed positivity that was associated with familiarity-based source memory in the high-unitization condition only and a parietally distributed positivity that was associated with recollection-based source memory in both the high- and low-unitization conditions. The ERP and behavioral findings provide converging evidence for the idea that familiarity can contribute to source recognition, particularly when source information is encoded as an item detail.

    Full Text Available The hippocampus has classically been associated with episodic memory, but is sometimes also recruited during semantic memory tasks, especially for the skilled exploration of familiar information. Cognitive control mechanisms guiding semantic memory search may benefit from the set of cognitive processes at stake during musical training. Here, we examined using functional magnetic resonance imaging, whether musical expertise would promote the top–down control of the left inferior frontal gyrus (LIFG over the generation of hippocampally based goal-directed thoughts mediating the familiarity judgment of proverbs and musical items. Analyses of behavioral data confirmed that musical experts more efficiently access familiar melodies than non-musicians although such increased ability did not transfer to verbal semantic memory. At the brain level, musical expertise specifically enhanced the recruitment of the hippocampus during semantic access to melodies, but not proverbs. Additionally, hippocampal activation contributed to speed of access to familiar melodies, but only in musicians. Critically, causal modeling of neural dynamics between LIFG and the hippocampus further showed that top–down excitatory regulation over the hippocampus during familiarity decision specifically increases with musical expertise – an effect that generalized across melodies and proverbs. At the local level, our data show that musical expertise modulates the online recruitment of hippocampal response to serve semantic memory retrieval of familiar melodies. The reconfiguration of memory network dynamics following musical training could constitute a promising framework to understand its ability to preserve brain functions.

    This study suggests that familiarity and novelty preferences in infant experimental tasks can in some instances be interpreted together as a single indicator of language advance. We provide evidence to support this idea based on our use of the auditory headturn preference paradigm to record responses to words likely to be either familiar or unfamiliar to infants. Fifty-nine 10-month-old infants were tested. The task elicited mixed preferences: familiarity (longer average looks to the words likely to be familiar to the infants), novelty (longer average looks to the words likely to be unfamiliar) and no-preference (similar-length of looks to both type of words). The infants who exhibited either a familiarity or a novelty response were more advanced on independent indices of phonetic advance than the infants who showed no preference. In addition, infants exhibiting novelty responses were more lexically advanced than either the infants who exhibited familiarity or those who showed no-preference. The results provide partial support for Hunter and Ames’ (1988) developmental model of attention in infancy and suggest caution when interpreting studies indexed to chronological age. PMID:27242624

  11. You look familiar, but I don’t care: Lure rejection in hybrid visual and memory search is not based on familiarity

    In “hybrid” search tasks, observers hold multiple possible targets in memory while searching for those targets amongst distractor items in visual displays. Wolfe (2012) found that, if the target set is held constant over a block of trials, RTs in such tasks were a linear function of the number of items in the visual display and a linear function of the log of the number of items held in memory. However, in such tasks, the targets can become far more familiar than the distractors. Does this “familiarity” – operationalized here as the frequency and recency with which an item has appeared – influence performance in hybrid tasks In Experiment 1, we compared searches where distractors appeared with the same frequency as the targets to searches where all distractors were novel. Distractor familiarity did not have any reliable effect on search. In Experiment 2, most distractors were novel but some critical distractors were as common as the targets while others were 4× more common. Familiar distractors did not produce false alarm errors, though they did slightly increase response times (RTs). In Experiment 3, observers successfully searched for the new, unfamiliar item among distractors that, in many cases, had been seen only once before. We conclude that when the memory set is held constant for many trials, item familiarity alone does not cause observers to mistakenly confuse target with distractors. PMID:26191615

    Full Text Available El nevus blanco esponjoso (NBE es una rara condición autosómica dominante, caracterizada por placas blancas bilaterales en la mucosa, de aspecto esponjoso, blandas a la palpación y que pueden escamarse. Los tratamientos son paliativos; y el uso de antibióticos, en especial la tetraciclina, ha demostrando buenos resultados en su control. Este trabajo presenta tres casos clínicos de una familia afectada por NBE, donde se discuten los posibles diagnósticos diferenciales y conductas terapéuticas indicadas. Un paciente masculino de 52 años de edad acudió a la clínica aquejado de lesiones blancas bilaterales. El paciente notó las lesiones 30 años antes, sin lograr un diagnóstico final de las mismas. Después de la anamnesis y del examen clínico fue realizada una biopsia incisional. La reunión de los datos clínicos e histopatológicos llevó al diagnóstico de NBE. Se le solicitó al paciente que indagase entre sus familiares con respecto a lesiones semejantes. Se detectó que el hijo de 19 años y la hija de 25 eran portadores de placas blancas en la mucosa yugal. Como no había afectación estética, se optó por no intervenir en las lesiones. El nevus blanco esponjoso es una lesión genética que debe ser diferenciada de otras patologías localizadas y sistémicas importantes, que tienen repercusiones serias para el individuo. Como no hay un tratamiento curativo para el NBE, el papel del cirujano dentista es diagnosticar esta lesión, aclarar al paciente sobre la naturaleza benigna y autolimitante del NBE y si fuera necesario desde el punto de vista estético, aplicar diferentes modalidades terapéuticas.The aim of present paper is to introduce three clinical cases from a family affected from nevus spongiosus albus (NSA and also to discuss the possible differential diagnoses as well as the therapeutical behaviors to be adopted.

    Full Text Available There is no scientific evidence in the literature indicating that maximal isometric strength measures can be assessed within 3 trials. We questioned whether the results of isometric squat-related studies in which maximal isometric squat strength (MISS testing was performed using limited numbers of trials without pre-familiarization might have included systematic errors, especially those resulting from acute learning effects. Forty resistance-trained male participants performed 8 isometric squat trials without pre-familiarization. The highest measures in the first “n” trials (3 ≤ n ≤ 8 of these 8 squats were regarded as MISS obtained using 6 different MISS test methods featuring different numbers of trials (The Best of n Trials Method [BnT]. When B3T and B8T were paired with other methods, high reliability was found between the paired methods in terms of intraclass correlation coefficients (0.93-0.98 and coefficients of variation (3.4-7.0%. The Wilcoxon’s signed rank test indicated that MISS obtained using B3T and B8T were lower (p < 0.001 and higher (p < 0.001, respectively, than those obtained using other methods. The Bland- Altman method revealed a lack of agreement between any of the paired methods. Simulation studies illustrated that increasing the number of trials to 9-10 using a relatively large sample size (i.e., ≥ 24 could be an effective means of obtaining the actual MISS values of the participants. The common use of a limited number of trials in MISS tests without pre-familiarization appears to have no solid scientific base. Our findings suggest that the number of trials should be increased in commonly used MISS tests to avoid learning effect-related systematic errors

    There are few quantitative examinations of the extent to which dogs discriminate between familiar and unfamiliar persons. In our study we have investigated whether dogs show differential behaviour towards humans of different degrees of familiarity (owner, familiar person, unfamiliar person). Dogs and humans were observed in eight test situations: (1) Three-way strange situation test, (2) Calling in from food, (3) Obedience test, (4) Walking away, (5) Threatening approach, (6) Playful interaction, (7) Food inhibition test and (8) Manipulation of the dog's body. Dogs distinguished between the owner and the two other test partners in those tests which involved separation from the owner (Test 1, 4), were aversive for the dog (Test 5) or involved playing interaction (Test 6). Our results revealed that the owner cannot be replaced by a familiar person in situations provoking elevated anxiety and fear. In contrasts, dogs did not discriminate between the owner and the familiar person in those tests that were based on obedient behaviour or behaviour towards an assertive person (Tests 2, 3, 7 and 8). Dogs' former training experience reduced the difference between their behaviour towards the owner and the familiar person in situations requiring obedience but it did not mask it totally. The dogs' behaviour towards each of the humans participating in the tests was consistent all over the test series. In summary, dogs discriminated between their owner and the unfamiliar person and always preferred the owner to the unfamiliar person. However, the discrimination between the owner and the familiar person is context-specific. This article is part of a Special Issue entitled: Canine Behavior. Copyright © 2014 Elsevier B.V.

  4. Using guitar learning to probe the Action Observation Network's response to visuomotor familiarity.

    Watching other people move elicits engagement of a collection of sensorimotor brain regions collectively termed the Action Observation Network (AON). An extensive literature documents more robust AON responses when observing or executing familiar compared to unfamiliar actions, as well as a positive correlation between amplitude of AON response and an observer's familiarity with an observed or executed movement. On the other hand, emerging evidence shows patterns of AON activity counter to these findings, whereby in some circumstances, unfamiliar actions lead to greater AON engagement than familiar actions. In an attempt to reconcile these conflicting findings, some have proposed that the relationship between AON response amplitude and action familiarity is nonlinear in nature. In the present study, we used an elaborate guitar training intervention to probe the relationship between movement familiarity and AON engagement during action execution and action observation tasks. Participants underwent fMRI scanning while executing one set of guitar sequences with a scanner-compatible bass guitar and observing a second set of sequences. Participants then acquired further physical practice or observational experience with half of these stimuli outside the scanner across 3 days. Participants then returned for an identical scanning session, wherein they executed and observed equal numbers of familiar (trained) and unfamiliar (untrained) guitar sequences. Via region of interest analyses, we extracted activity within AON regions engaged during both scanning sessions, and then fit linear, quadratic and cubic regression models to these data. The data best support the cubic regression models, suggesting that the response profile within key sensorimotor brain regions associated with the AON respond to action familiarity in a nonlinear manner. Moreover, by probing the subjective nature of the prediction error signal, we show results consistent with a predictive coding account of

    Social animals learn to perceive their social environment, and their social skills and preferences are thought to emerge from greater exposure to and hence familiarity with some social signals rather than others. Familiarity appears to be tightly linked to multisensory integration. The ability to differentiate and categorize familiar and unfamiliar individuals and to build a multisensory representation of known individuals emerges from successive social interactions, in particular with adult, experienced models. In different species, adults have been shown to shape the social behavior of young by promoting selective attention to multisensory cues. The question of what representation of known conspecifics adult-deprived animals may build therefore arises. Here we show that starlings raised with no experience with adults fail to develop a multisensory representation of familiar and unfamiliar starlings. Electrophysiological recordings of neuronal activity throughout the primary auditory area of these birds, while they were exposed to audio-only or audiovisual familiar and unfamiliar cues, showed that visual stimuli did, as in wild-caught starlings, modulate auditory responses but that, unlike what was observed in wild-caught birds, this modulation was not influenced by familiarity. Thus, adult-deprived starlings seem to fail to discriminate between familiar and unfamiliar individuals. This suggests that adults may shape multisensory representation of known individuals in the brain, possibly by focusing the young's attention on relevant, multisensory cues. Multisensory stimulation by experienced, adult models may thus be ubiquitously important for the development of social skills (and of the neural properties underlying such skills) in a variety of species.

    Full Text Available El ciberacoso es un fenómeno de creciente preocupación social que afecta cada vez más a niños y adolescentes de todos los países desarrollados. A diferencia de la considerable literatura que hay sobre las relaciones entre el acoso escolar y el contexto familiar y escolar, todavía hay pocos trabajos sobre la influencia de estos entornos sociales en el problema del ciberacoso. Mediante una metodología cuantitativa, el objetivo principal del presente estudio fue analizar la influencia del contexto escolar y familiar en víctimas de ciberacoso. La muestra estuvo formada por 1.062 adolescentes (51,5% chicos y 48,5% chicas, de edades comprendidas entre los 12 y los 18 años (M=14,5; DT=1,62. Se establecieron tres grupos de contraste: cibervíctimas severas, cibervíctimas moderadas y no víctimas de ciberacoso. Los resultados del análisis de varianza indicaron que las cibervíctimas severas en comparación con las no víctimas puntúan significativamente más alto en conflicto familiar y obtienen puntuaciones más bajas en el resto de variables familiares (autoestima familiar, cohesión y expresividad, y variables escolares (implicación, afiliación y ayuda al profesor, consideradas en el estudio. Los análisis de regresión revelaron que la autoestima académica y familiar y algunas dimensiones del clima familiar y escolar predicen la cibervictimización en la adolescencia. Estos novedosos resultados muestran la importancia de incluir a la familia y a la escuela en los programas de prevención del ciberacoso.

    Full Text Available This Special Feature, "Nudging Evolution? Critical Exploration of the Potential and Limitations of the Concept of Institutional Fit for the Study and Adaptive Management of Social-Ecological Systems," aims to contribute toward the development of social theory and social research methods for the study of social-ecological system dynamics. Our objective is to help strengthen the academic discourse concerning if, and if so, how, to what extent, and in what concrete ways the concept of institutional "fit" might play a role in helping to develop better understanding of the social components of interlinkages between the socioeconomic-cultural and ecological dynamics of social-ecological systems. Two clearly discernible patterns provide a map of this Special Feature: (1 One pattern is the authors' positions regarding the place and role of normativity within their studies and assessment of institutional fit. Some place this at the center of their studies, exploring phenomena endogenous to the process of defining what constitutes institutional fit, whereas others take the formation of norms as a phenomenon exogenous to their study. (2 Another pattern is the type of studies presented: critiques and elaborations of the theory, methods for judging qualities of fit, and/or applied case studies using the concept. As a body of work, these contributions highlight that self-understanding of social-ecological place, whether explicit or implicit, constitutes an important part of the study object, i.e., the role of institutions in social-ecological systems, and that this is, at the same time, a crucial point of reference for the scholar wishing to evaluate what constitutes institutional fit and how it might be brought into being.

    Full Text Available Several studies of semantic memory in non-musical domains involving recognition of items from long-term memory have shown an age-related shift from the medial temporal lobe structures to the frontal lobe. However, the effects of aging on musical semantic memory remain unexamined. We compared activation associated with recognition of familiar melodies in younger and older adults. Recognition follows successful retrieval from the musical lexicon that comprises a lifetime of learned musical phrases. We used the sparse-sampling technique in fMRI to determine the neural correlates of melody recognition by comparing activation when listening to familiar versus unfamiliar melodies, and to identify age differences. Recognition-related cortical activation was detected in the right superior temporal, bilateral inferior and superior frontal, left middle orbitofrontal, bilateral precentral, and left supramarginal gyri. Region-of-interest analysis showed greater activation for younger adults in the left superior temporal gyrus and for older adults in the left superior frontal, left angular, and bilateral superior parietal regions. Our study provides powerful evidence for these musical memory networks due to a large sample (N = 40 that includes older adults. This study is the first to investigate the neural basis of melody recognition in older adults and to compare the findings to younger adults.

    It was demonstrated that the entanglement evolution of a specially designed quantum state in the bistochastic channel is asymmetric. In this work, we generalize the study of the quantum correlations, including entanglement and quantum discord, evolution asymmetry to various quantum channels. We found that the asymmetry of entanglement and quantum discord only occurs in some special quantum channels, and the behavior of the entanglement evolution may be quite different from the behavior of the quantum discord evolution. To quantum entanglement, in some channels it decreases monotonously with the increase of the quantum channel intensity. In some other channels, when we increase the intensity of the quantum channel, it decreases at first, then keeps zero for some time, and then rises up. To quantum discord, the evolution becomes more complex and you may find that it evolutes unsmoothly at some points. These results illustrate the strong dependence of the quantum correlations evolution on the property of the quantum channels. (paper)

    This chapter deals with the radiotherapy and cytotoxic chemotherapy of the malignant lymphomas. Included within this group are Hodgkin's disease, non-Hodgkin's lymphoma, mycosis fungoides, and chronic lymphatic leukaemia. A further section deals with the myeloproliferative disorders, including granulocytic leukaemia, polycythaemia vera, and primary thrombocythaemia. Excluded are myeloma and reticulum cell sarcoma of bone and acute leukaemia. With regard to Hodgkin's disease, the past 25 years have seen general recognition of the curative potential of radiotherapy, at least in the local stages, and, more recently, awareness of the ability to achieve long-term survival after combination chemotherapy in generalised or in recurrent disease. At the same time the importance of staging has become appreciated and the introduction of procedures such as lymphography, staging laparotomy, and computer tomography (CT) has enormously increased its reliability. Advances have not been so dramatic in the complex group of non-Hodgkins's lymphomas, but are still very real

  15. Dogs’ attention towards humans depends on their relationship, not only on social familiarity

    2014-01-01

    Both in humans and non-human animals it has been shown that individuals attend more to those they have previously interacted with and/or that they are more closely associated with than to unfamiliar individuals. Whether this preference is mediated by mere social familiarity based on exposure or by the specific relationship between the two individuals, however, remains unclear. The domestic dog is an interesting subject in this line of research as it lives in the human environment and regularly interacts with numerous humans, yet it often has a particularly close relationship with its owner. Therefore, we investigated how long dogs (Canis familiaris) would attend to the actions of two familiar humans and one unfamiliar experimenter, while varying whether dogs had a close relationship with only one or both familiar humans. Our data provide evidence that social familiarity by itself cannot account for dogs’ increased attention towards their owners since they only attended more to those familiar humans with whom they also had a close relationship.

  16. Familiarity knowledge in student nurses' clinical studies: exemplified by student nurses in palliative care.

    Haugan, Grethe; Hanssen, Ingrid

    2012-01-01

    In this article based on a literary study, the form of knowledge named familiarity knowledge is examined. Although rooted in the philosophical tradition of Wittgenstein and Polanyi, the development of familiarity knowledge is tied in with clinical practice and particular patients and contexts while paying attention to the framework factors influencing the setting as a whole as well as with theoretical knowledge relevant to the situation at hand. Palliative care makes a backdrop for some of the discussion. Familiarity knowledge can never be context free and attends to that which is unique in every nurse-patient relationship. Both assertive and familiarity knowledge are needed to care for dying patients in a competent, sensitive, and truly caring manner. Mentors need to help students synthesize assertive knowledge and familiarity knowledge during their clinical studies to enrich both kinds of knowledge and deepen their understanding. Student nurses expertly mentored and tutored while caring for dying patients living at home become, for instance, less apprehensive about facing dying patients than students not so mentored. Nurses need to understand the complexity of nursing care to be able to see the uniqueness of the situation and approach the individual patient on the bases of experience and insight.

  17. Rhesus monkeys see who they hear: spontaneous cross-modal memory for familiar conspecifics.

    Directory of Open Access Journals (Sweden)

    Ikuma Adachi

    Full Text Available Rhesus monkeys gather much of their knowledge of the social world through visual input and may preferentially represent this knowledge in the visual modality. Recognition of familiar faces is clearly advantageous, and the flexibility and utility of primate social memory would be greatly enhanced if visual memories could be accessed cross-modally either by visual or auditory stimulation. Such cross-modal access to visual memory would facilitate flexible retrieval of the knowledge necessary for adaptive social behavior. We tested whether rhesus monkeys have cross-modal access to visual memory for familiar conspecifics using a delayed matching-to-sample procedure. Monkeys learned visual matching of video clips of familiar individuals to photographs of those individuals, and generalized performance to novel videos. In crossmodal probe trials, coo-calls were played during the memory interval. The calls were either from the monkey just seen in the sample video clip or from a different familiar monkey. Even though the monkeys were trained exclusively in visual matching, the calls influenced choice by causing an increase in the proportion of errors to the picture of the monkey whose voice was heard on incongruent trials. This result demonstrates spontaneous cross-modal recognition. It also shows that viewing videos of familiar monkeys activates naturally formed memories of real monkeys, validating the use of video stimuli in studies of social cognition in monkeys.

  18. The role of issue familiarity and social norms: findings on new college students’ alcohol use intentions

    Full Text Available Background. Scholars in a variety of disciplines are interested in understanding the conditions under which social norms affect human behavior. Following the distinction made between descriptive and injunctive norms by the focus theory of normative conduct, the theory of normative social behavior predicts that the influence of descriptive norms on behavior is moderated by injunctive norms, outcome expectations, and group identity. We extended the theory by testing the proposition that the influence of descriptive norms on behavior would be greater under conditions of greater issue familiarity, defined as the ease with which one can cognitively access the behavior or behavioral issue. Design and Methods. The model was tested in the domain of alcohol consumption intentions by conducting a survey among incoming students (n=719 to a large university in the United States. Data indicated that students in the sample were well representative of the university population. Results. The influence of descriptive norms on behavioral intentions was moderated by issue familiarity, as predicted. Familiarity was a facilitator of behavior: the influence of descriptive norms on behavioral intentions was greater under conditions of high, rather than low, familiarity. The overall model explained 53% of the variance in alcohol consumption intentions. Conclusions. Public health interventions promoting health behaviors need to take into account the extent to which the behaviors are familiar to the target audience. The influence of norms appears to be weaker when the behavior is unfamiliar or novel. Implications for theory and interventions for reducing alcohol consumption are discussed.

    Individuals within animal groups may differ in personality and degree of familiarity raising the question of how this influences their social interactions. In Iberian magpies Cyanopica cooki, a portion of first-year males engage in cooperative behaviours and dispersal, allowing addressing this question. In this study, we first investigate the relationship between colony familiarity (native versus foreign) and reproductive status (breeding versus helping) of males during 21 years. Secondly, we measure the exploratory behaviour and monitor reproductive status of a sample of individuals with different colony familiarity during 2 years. Long-term monitoring revealed that foreign individuals were more likely breeders. The analysis on the subset of individuals in which exploratory behaviour was measured revealed a mediatory effect of exploratory behaviour in the association between colony familiarity and helping behaviour. Specifically, among foreign individuals, higher explorative males were more frequently involved in helping behaviour than lower explorative ones. Conversely, among native males, breeders were more explorative than helpers. Our results suggest that aspects of personality may mediate the value of familiarity in reproductive tasks in social species. Copyright © 2016 Elsevier B.V. All rights reserved.

    Kenneled environments often prevent direct physical contact between dogs, potentially causing stress, and so it has been recommended that such contact should be provided. This study examined the effect of familiarity on the behavior of dogs during off-lead interaction. Kenneled dogs (3 breeds) were given 15-min off-lead interactions with a familiar dog and an unfamiliar dog; the behavior of the focal dog and the distance between the dogs were recorded. More time in contact and interaction behaviors were recorded at 0 to 3 min with unfamiliar dogs than with familiar dogs. At 9 to 12 min, familiar pairs spent more time within 5 body lengths and more time being followed than unfamiliar pairs, who spent more time at more than 5 body lengths apart. This suggests that the initial interaction is more important when dogs are unfamiliar, but once this "greeting" has occurred, unfamiliar pairs are more likely to investigate their surroundings independently rather than together. Breed differences were observed only at 0 to 3 min. The study suggests that familiarity should be taken into account when assessing the effectiveness of conspecific contact as a potential enrichment for kennel-housed dogs.

Para el análisis de datos se utilizan matrices de correlaciones bivariadas, el cálculo de ecuaciones estructurales y se sigue el procedimiento de análisis de efectos mediadores. Los resultados muestran que las distintas dimensiones de la autoestima median conjuntamente el 82% de la relación entre el funcionamiento familiar y el consumo de sustancias de los adolescentes. Además, se observa, por un lado, un efecto protector de las autoestimas familiar y escolar frente a la implicación en el consumo de sustancias y, por otro, un efecto de riesgo de las autoestimas social y física. Finalmente, se discute el rol de la autoestima como un mediador para determinadas influencias del contexto familiar y como un recurso psicosocial paradójico en relación con el consumo de sustancias en la edad adolescente.

    Isometric multi-joint tests are considered reliable and have strong relationships with 1RM performance. However, limited evidence is available for the isometric squat in terms of effects of familiarization and reliability. This study aimed to assess, the effect of familiarization, stability reliability, determine the smallest detectible difference, and the correlation of the isometric squat test with 1RM squat performance. Thirty-six strength-trained participants volunteered to take part in this study. Following three familiarization sessions, test-retest reliability was evaluated with a 48-hour window between each time point. Isometric squat peak, net and relative force were assessed. Results showed three familiarizations were required, isometric squat had a high level of stability reliability and smallest detectible difference of 11% for peak and relative force. Isometric strength at a knee angle of ninety degrees had a strong significant relationship with 1RM squat performance. In conclusion, the isometric squat is a valid test to assess multi-joint strength and can discriminate between strong and weak 1RM squat performance. Changes greater than 11% in peak and relative isometric squat performance should be considered as meaningful in participants who are familiar with the test.

    2013-02-05

    Familiarity discrimination has a significant impact on the pattern of food intake across species. However, the mechanism by which the recognition memory controls feeding is unclear. Here, we show that the nematode Caenorhabditis elegans forms a memory of particular foods after experience and displays behavioral plasticity, increasing the feeding response when they subsequently recognize the familiar food. We found that recognition of familiar food activates the pair of ADF chemosensory neurons, which subsequently increase serotonin release. The released serotonin activates the feeding response mainly by acting humorally and directly activates SER-7, a type 7 serotonin receptor, in MC motor neurons in the feeding organ. Our data suggest that worms sense the taste and/or smell of novel bacteria, which overrides the stimulatory effect of familiar bacteria on feeding by suppressing the activity of ADF or its upstream neurons. Our study provides insight into the mechanism by which familiarity discrimination alters behavior.DOI:http://dx.doi.org/10.7554/eLife.00329.001.

  9. Asymmetrical DNA replication promotes evolution: disparity theory of evolution.

    Science.gov (United States)

    Furusawa, M; Doi, H

    1998-01-01

    Heredity is guaranteed by faithful DNA replication whereas evolution depends upon errors accompanying DNA replication. This contradiction existing between heredity and evolution cannot be resolved in an individual organism, but only in terms of a population, in that a delicate balance exists between wild type and variants in a population which is necessary for the survival of the species. Namely, there seems to be a key in the mechanism of DNA replication to solve some problems of evolution. DNA is replicated semiconservatively using the leading and discontinuous lagging strands. According to our 'disparity theory of evolution', the existence of a sufficient fidelity difference between the leading and lagging strands is advantageous in terms of evolution, because the diversity of genotypes is enlarged but genotypes that have occurred in the past are guaranteed. In theory, by artificially increasing the fidelity difference between the leading and lagging strand ('disparity mutator'), evolution is accelerated while avoiding the extinction of the population. Using a disparity mutator, we should be able to improve living things, including multicellular organisms, within constrained conditions. A double-stranded algorithm, which mimics the structure and replication manner of DNA, is promising for solving optimization problems.

    A freely available Python code for modeling supernova remnant (SNR) evolution has been created. This software is intended for two purposes: to understand SNR evolution and to use in modeling observations of SNR for obtaining good estimates of SNR properties. It includes all phases for the standard path of evolution for spherically symmetric SNRs. In addition, alternate evolutionary models are available, including evolution in a cloudy ISM, the fractional energy-loss model, and evolution in a hot low-density ISM. The graphical interface takes in various parameters and produces outputs such as shock radius and velocity versus time, as well as SNR surface brightness profile and spectrum. Some interesting properties of SNR evolution are demonstrated using the program.

    When and how does one learn to associate emotion with music? This study attempted to address this issue by examining whether preschool children use tempo as a cue in determining whether a song is happy or sad. Instrumental versions of children's songs were played at different tempos to adults and children ages 3 to 5 years. Familiar and unfamiliar songs were used to examine whether familiarity affected children's identification of emotion in music. The results indicated that adults, 4 year olds and 5 year olds rated fast songs as significantly happier than slow songs. However, 3 year olds failed to rate fast songs differently than slow songs at above-chance levels. Familiarity did not significantly affect children's identification of happiness and sadness in music.

    In fMRI analyses, the posterior parietal cortex (PPC) is particularly active during the successful retrieval of episodic memory. To delineate the neural correlates of episodic retrieval more succinctly, we compared retrieval of recently learned spatial locations (photographs of buildings) with retrieval of previously familiar locations (photographs of familiar campus buildings). Episodic retrieval of recently learned locations activated a circumscribed region within the ventral PPC (anterior angular gyrus and adjacent regions in the supramarginal gyrus) as well as medial PPC regions (posterior cingulated gyrus and posterior precuneus). Retrieval of familiar locations activated more posterior regions in the ventral PPC (posterior angular gyrus, LOC) and more anterior regions in the medial PPC (anterior precuneus and retrosplenial cortex). These dissociable effects define more precisely PPC regions involved in the retrieval of recent, contextually bound information as opposed to regions involved in other processes, such as visual imagery, scene reconstruction, and self-referential processing.

  18. An odd manifestation of the Capgras syndrome: loss of familiarity even with the sexual partner.

    2008-06-01

    We report the case of a patient who presented visual hallucinations and identification disorders associated with a Capgras syndrome. During the Capgras periods, there was not only a misidentification of his wife's face, but also a more global perceptive and emotional sexual identification disorder. Thus, he had sexual intercourse with his wife's "double" without having the slightest recollection feeling of familiarity towards his "wife" and even changed his sexual habits. To the best of our knowledge, he is the only neurological patient who made his wife a mistress. Starting from this global familiarity loss, we discuss the mechanism of Capgras delusion with reference to the role of the implicit system of face recognition. Such behavior of familiarity loss not only with face but also with all intimacy aspects argues for a specific disconnection between the ventral visual pathway of face identification and the limbic system involved in emotional and episodic memory contents.

    Recognition memory can be supported by both the assessment of the familiarity of an item and by the recollection of the context in which an item was encountered. The neural substrates of these memory processes are controversial. To address these issues we applied repetitive transcranial magnetic stimulation (rTMS) over the right and left dorsolateral prefrontal cortex (DLPFC) of healthy subjects performing a remember/know task. rTMS disrupted familiarity judgments when applied before encoding of stimuli over both right and left DLPFC. rTMS disrupted recollection when applied before encoding of stimuli over the right DLPFC. These findings suggest that the DLPFC plays a critical role in recognition memory based on familiarity as well as recollection. PMID:18413912

    Cross-situational continuity and change in anxious solitary girls' behavior and peer relations were examined in interactions with familiar versus unfamiliar playmates. Fourth-grade girls (N=209, M age=9.77 years, half African American, half European American) were identified as anxious solitary or behaviorally normative using observed and teacher-reported behavior among classmates. Subsequently, girls participated in 1-hr play groups containing 5 same-race familiar or unfamiliar girls for 5 consecutive days. Results support both cross-situational continuity and change in anxious solitary girls' behavior and peer relations. Although anxious solitary girls exhibited difficulty interacting with both familiar and unfamiliar playmates relative to behaviorally normative girls, elements of their behavior improved in unfamiliar play groups, a context in which they received less peer mistreatment.

    Autistic traits vary across the general population, and are linked with face recognition ability. Here we investigated potential links between autistic traits and voice recognition ability for personally familiar voices in a group of 30 listeners (15 female, 16-19 years) from the same local school. Autistic traits (particularly those related to communication and social interaction) were negatively correlated with voice recognition, such that more autistic traits were associated with fewer familiar voices identified and less ability to discriminate familiar from unfamiliar voices. In addition, our results suggest enhanced accessibility of personal semantic information in women compared to men. Overall, this study establishes a detailed pattern of relationships between voice identification performance and autistic traits in the general population.

    This review begins with a definition of biological evolution and a description of its general principles. This is followed by a presentation of the biological basis of culture, specifically the concept of social selection. Further, conditions for cultural evolution are proposed, including a suggestion for language being the cultural replicator corresponding to the concept of the gene in biological evolution. Principles of cultural evolution are put forward and compared to the principles of biological evolution. Special emphasis is laid on the principle of selection in cultural evolution, including presentation of the concept of cultural fitness. The importance of language as a necessary condition for cultural evolution is stressed. Subsequently, prime differences between biological and cultural evolution are presented, followed by a discussion on interaction of our genome and our culture. The review aims at contributing to the present discussion concerning the modern development of the general theory of evolution, for example by giving a tentative formulation of the necessary and sufficient conditions for cultural evolution, and proposing that human creativity and mind reading or theory of mind are motors specific for it. The paper ends with the notion of the still ongoing coevolution of genes and culture.

    Full Text Available As relações afetivas e pessoais ao longo da vida podem determinar as relações familiares no processo do envelhecer humano. Este trabalho teve por objetivo avaliar a funcionalidade familiar de idosos pertencentes a um movimento de alfabetização de adultos e identificar quem escolheriam para cuidar deles na velhice. Trata-se de um estudo descritivo e transversal, baseado nos pressupostos do método quantitativo e qualitativo de investigação. Para a avaliação da funcionalidade familiar utilizou-se o Apgar de Família proposto por SMILKSTEIN (1978 e os dados foram analisados estatisticamente segundo medidas de freqüência. Foram avaliados 93 idosos. Para a compreensão da escolha do cuidador foram realizadas entrevistas em profundidade com 9 idosos, sendo três de cada categoria do Apgar. As entrevistas foram analisadas, segundo o Modelo de Análise de Conteúdo, categoria Análise Temática proposta por BARDIN (1977.Todos os cuidados éticos que regem pesquisas com seres humanos foram respeitados. Os resultados do Apgar de família mostram que 81 idosos apresentaram boa funcionalidade familiar, 8 moderada disfunção e 4 elevada disfunção familiar. Os resultados das entrevistas mostram que, nas três categorias do Apgar, a escolha do cuidador foi a mesma no que diz respeito ao gênero (mulher, ao grau de parentesco (filha, à composição familiar (multigeracional, à história de vida e ao relacionamento. “Quem irá empurrar minha cadeira de rodas” é uma escolha determinada por valores sociais e culturais e pela história de vida de cada um. É multideterminada, multivariada e se processa ao longo da vida.

    Full Text Available Emotional arousal appears to be a major contributing factor to the pleasure that listeners experience in response to music. Accordingly, a strong positive correlation between self-reported pleasure and electrodermal activity (EDA, an objective indicator of emotional arousal, has been demonstrated when individuals listen to familiar music. However, it is not yet known to what extent familiarity contributes to this relationship. In particular, as listening to familiar music involves expectations and predictions over time based on veridical knowledge of the piece, it could be that such memory factors plays a major role. Here, we tested such a contribution by using musical stimuli entirely unfamiliar to listeners. In a second experiment we repeated the novel music to experimentally establish a sense of familiarity. We aimed to determine whether (1 pleasure and emotional arousal would continue to correlate when listeners have no explicit knowledge of how the tones will unfold, and (2 whether this could be enhanced by experimentally-induced familiarity. In the first experiment, we presented 33 listeners with 70 unfamiliar musical excerpts in two sessions. There was no relationship between the degree of experienced pleasure and emotional arousal as measured by EDA. In the second experiment, 7 participants listened to 35 unfamiliar excerpts over two sessions separated by 30 minutes. Repeated exposure significantly increased EDA, even though individuals did not explicitly recall having heard all the pieces before. Furthermore, increases in self-reported familiarity significantly enhanced experienced pleasure and there was a general, though not significant, increase in EDA. These results suggest that some level of expectation and predictability mediated by prior exposure to a given piece of music play an important role in the experience of emotional arousal in response to music.

    Full Text Available Introduction & Objective: Pain in neonates can lead to various risks. So, it seems essential to find a simple, safe, and acceptable method for relieving pain. The objective of this study was to assess the effectiveness of olfactory stimuli (familiar and unfamiliar on physiological and behavioral responses to the pain of arterial blood draws in term neonates. Materials & Methods: In this quasi-experimental clinical trial, according to the conditions of the study 135 term neonates were chosen by convenience sampling and were assigned to three groups. During the procedure, familiar odor group was presented with the vanilla smell with which they had been familiarized prior to the procedure for 9 hours. Unfamiliar odor group was presented with the vanilla smell to which they had not been previously exposed, and the control group was presented with no odor. The heart rate and O2 saturation levels were measured before, after inserting and after removing the needle. Also, their cry duration was measured from onset until a crying free interval of more than five seconds. Results: The infants exposed to the familiar odor cried significantly less during the procedure compared to the unfamiliar odor and no odor group (P<0.001. Moreover, there was no statistically significant difference in the heart rate among the groups after inserting and removing the needle and in the O2 saturation rate after inserting the needle. The O2 saturation rate was significantly higher in the familiar odor group compared with the other groups (p<0.05 after the needle removal. Conclusion: A familiar odor is effective in reducing crying during arterial blood draws in neonates, but does not affect on physiological parameters. (Sci J Hamadan Univ Med Sci 2011;18(1:10-19

    Full Text Available http://dx.doi.org/10.5007/1807-1384.2017v14n1p152 Este artigo consiste em um recorte de minha pesquisa de Mestrado, na qual investiguei a experiência da conjugalidade homossexual a partir de entrevistas com quatro casais, tendo como referenciais teóricos os estudos queer. No presente texto, parto de recentes contribuições sobre parentesco de Marilyn Strathern (2005/2015, especialmente suas discussões sobre parentalidade e demais relações familiares, para apresentar as narrativas de um dos casais de mulheres entrevistadas e pensar os (desencontros entre certa ordem familiar instituída e novos arranjos familiares. Dentre as muitas expectativas, planos e dilemas, observamos que, no tocante à geração de filhos, são temidos os questionamentos da família de origem quanto à identificação e inclusão do genitor na rede familiar, à orientação sexual das mães etc. O discurso do casal aponta para uma complexa trama que envolve variadas possibilidades de arranjos parentais e familiares, sexualidades e afetos. Não obstante, o casal de mulheres entrevistadas parece operar sob uma reiteração subversiva: as possibilidades são discutidas e negociadas tendo a família de origem como referência legitimadora, como instituição que se autoriza a indagar seus vínculos, afetos e desejos. Nesse sentido, o casal analisado apropria-se de determinadas referências familiares porque estas dizem respeito às histórias individuais, ao mesmo tempo em que as negociam, reformulam-nas, submetem-nas às reavaliações que fazem em seu projeto de uma vida a dois ‘alternativa’.

    Full Text Available En este estudio se analizan las relaciones entre las actitudes, valores e intereses familiares percibidos sobre la actividad físico-deportiva en general y de los hijos e hijas en particular, la autopercepción física y la actividad físico-deportiva realizada por los adolescentes. Participaron en el estudio 355 adolescentes de entre 12 y 22 años de las comunidades autónomas vasca y cántabra, a quienes se administraron el Cuestionario de Clima Familiar Deportivo y el Cuestionario de Autoconcepto Físico. Los resultados indican que un clima familiar deportivo favorable se relaciona con un autoconcepto físico más elevado y con una mayor frecuencia de actividad físico-deportiva. Así mismo, aparecen diferencias en cuanto al clima familiar deportivo en función del sexo de los participantes. Las chicas percibieron climas menos favorables que los chicos y se advirtieron diferencias a este respecto en función del sexo del resto de hijos e hijas de la unidad familiar. Los hijos de familias en las que sólo había chicos percibieron climas familiares deportivos más positivos que aquellos pertenecientes a familias en las que había chicos y chicas, siendo las percepciones más desfavorables las de las chicas que sólo tenían hermanas o eran hijas únicas

    Full Text Available Este artículo presenta los resultados del estudio cuyo objetivo fue establecer las diferencias en el riesgo familiar entre dos grupos de familias: con niños escolares de alto rendimiento y niños de bajo rendimiento académico en un centro educativo distrital de Bogotá. Metodología: estudio descriptivo comparativo transversal con un componente analítico y abordaje cuantitativo; la muestra fue de 186 familias, durante abril a julio de 2007. Los resultados muestran predominio de familias nucleares en ambos grupos (65%, relación inversa entre el riesgo familiar total evaluado por el instrumento RFT 7-70 y el rendimiento académico del escolar de la familia, es decir que las familias que registraron riesgo alto (9% y medio (31% en mayor proporción son familias con escolares de bajo rendimiento académico, frente al predominio del riesgo familiar bajo (78% en las familias con niños de alto rendimiento. Se aplicó t de student para diferencia de medias y se encontró asociación (P = 0,02 entre el riesgo familiar total alto y el bajo rendimiento académico del escolar. En conclusión, estos resultados sugieren principalmente que se deben priorizar los factores de riesgo que determinan mayor riesgo familiar en familias con escolares de bajo rendimiento académico y dar atención de salud integral con enfoque familiar e intersectorial, y participación activa de la comunidad. Continuar investigando en posibles asociaciones entre salud individual, prácticas de salud, educación, ambiente socioeconómico y psicoafectivo de la familia y el logro educativo de escolares en familias con niños en edad escolar.

  13. The Comprehension of Familiar and Novel Metaphoric Meanings in Schizophrenia: A Pilot Study

    Full Text Available Miscomprehension of nonliteral (“figurative” language like metaphors, proverbs, idioms, and ironic expressions by patients with schizophrenia is a phenomenon mentioned already in historical psychiatric descriptions. However, it was only recently that studies did differentiate between novel and conventional metaphors, a factor that is known to influence the difficulty of comprehension in healthy subjects. Further, familiarity with stimuli is an important factor for comprehension, which was not recommended in utmost previous studies. In this study, 23 patients with DSM IV schizophrenia and 19 healthy control subjects performed a newly-developed German metaphor comprehension test with three types of stimuli: novel metaphors, conventional German metaphors, and meaningless statements. During the test procedure, participants indicated familiarity with the stimulus and then matched the meaning with one out of four given alternatives. Familiarity rankings did not significantly differ between patients and control subjects. However, on descriptive level, there was a tendency for healthy controls to be more familiar with conventional metaphors than schizophrenic patients. Further, comprehension of conventional and novel metaphors differed significantly between the groups, with higher performance in healthy controls. Considering only those metaphors that had been ranked as familiar, patients only revealed significant lower performance opposed to controls regarding novel metaphors, while they did not differ in conventional metaphors. Taken together, the results indicate that patients with schizophrenia might show an altered way of comprehension in novel metaphors, leading to more misunderstandings. However, their previously reported impairments in conventional metaphors might rather be due to a lack of familiarity with the stimuli—making conventional metaphors to novel metaphors in the individual case.

    Increased teammate familiarity in emergency medical services (EMS) promotes development of positive teamwork and protects against workplace injury. Measures were collected using archival shift records, workplace injury data, and cross-sectional surveys from a nationally representative sample of 14 EMS agencies employing paramedics, prehospital nurses, and other EMS clinicians. One thousand EMS clinicians were selected at random to complete a teamwork survey for each of their recent partnerships and tested the hypothesized role of teamwork as a mediator in the relationship between teammate familiarity and injury with the PROCESS macro. We received 2566 completed surveys from 333 clinicians, of which 297 were retained. Mean participation was 40.5% (standard deviation [SD] = 20.5%) across EMS agencies. Survey respondents were primarily white (93.8%), male (67.3%), and ranged between 21-62 years of age (M = 37.4, SD = 9.7). Seventeen percent were prehospital nurses. Respondents worked a mean of 3 shifts with recent teammates in the 8 weeks preceding the survey (M = 3.06, SD = 4.4). We examined data at the team level, which suggest positive views of teamwork (M = 5.92, SD = 0.69). Our hypothesis that increased teammate familiarity protects against adverse safety outcomes through development of positive teamwork was not supported. Teamwork factor Partner Adaptability and Backup Behavior is a likely mediator (odds ratio = 1.03, P = .05). When dyad familiarity is high and there are high levels of backup behavior, the likelihood of injury is increased. The relationship between teammate familiarity and outcomes is complex. Teammate adaptation and backup behavior is a likely mediator of this relationship in EMS teams with greater familiarity. Copyright © 2017 Emergency Nurses Association. Published by Elsevier Inc.
