    CHLOE is an image analysis unsupervised learning algorithm that detects peculiar galaxies in datasets of galaxy images. The algorithm first computes a large set of numerical descriptors reflecting different aspects of the visual content, and then weighs them based on the standard deviation of the values computed from the galaxy images. The weighted Euclidean distance of each galaxy image from the median is measured, and the peculiarity of each galaxy is determined based on that distance.

    Full Text Available In this article we reflect on the relevance of the family identity research of the women who have made the decision to terminate their pregnancy.  Family identity is defined as a specific form of personal and group identity that includes three aspects of family and self -perception as a family member: structural, emotional-evaluative and cognitional. Evaluation research of the women in a state of legal and civil marriage is given.  General and specific peculiarities of their family identity are emphasized. General peculiarities are interpersonal relationships perception in the family as distanced and family image rigidity. Various active-passive positions inside a married couple, common for women in legal or civil marriages, are attributed to specific peculiarities. DOI: http://dx.doi.org/10.12731/2218-7405-2013-7-5

    The environmental impact of a nuclear industry at an early stage of development is examined vis-a-vis the experience accumulated in studies on the environmental impact of the nuclear fuel cycle in a developed country. Differences in the optics of the nuclear industry in a developed country and that of segments of the public opinion are briefly discussed. Some peculiar aspects of a nuclear industry being implanted in a developing nation, including adoption of new legislation and regulations, are presented, taking into account the unusual opportunity to attack potential problems in advance. The unique example of the pre-operational survey of a region surrounding a uranium mine in a developing nation is mentioned as an example of cooperation between the nuclear industry and the scientific community to minimize the environmental impact of uranium mining operations. The potential environmental impact of other stages of the nuclear fuel cycle is also examined. Further cooperation between the nuclear industry and the scientific community of Latin American countries is suggested to minimize the environmental impact of the nuclear fuel cycle in nations starting nuclear programs.

    , setting a more rational hierarchy of decisions, getting close to the efficient management and the motivation of its workers. Within this context, the collective dose represents an indictor of excellence in management an the reflection of the workers' positive attitude. The author states that this change in mentality should not be forgotten in any new definition of this principle. The author agrees that avoiding the concept of limit does not necessarily mean lack of rigour, but affects the image of rigour. Therefore, if one is sensitive to public's risk perception, why not respect the rigour's perception? Nowadays, that a great number of countries have not yet finished the implementation process of the last ICRP recommendations, the author asks himself whether or not the timing of Clarke's proposal comes at the most convenient moment. Will not this new philosophy make futile such efforts? The author asserts that the positive and negative aspects of Clarke's approach are a reflection of its simplicity. If one thinks that awareness of social perception of hazard should be recognised in the essence of any protection system, simplicity and unity of criterion are a clear evidence of this virtue. On the opposite side, when its universality and visibility are taken to a particular scenario, completely and misunderstanding could arise and run the risk of losing essential values of the good practice. Although this proposal neither guarantees the stability against oncoming scientific evidences, nor ends the controversy on linear non-threshold response model, the author recognises the courage and brilliance of its philosophy and, also, considers that it is worth reflecting on it and taking advantage of its undoubted merits.

  6. Peculiar Supernovae

    Milisavljevic, Dan; Margutti, Raffaella

    2018-06-01

    What makes a supernova truly "peculiar?" In this review we attempt to address this question by tracing the history of the use of "peculiar" as a descriptor of non-standard supernovae back to the original binary spectroscopic classification of Type I vs. Type II proposed by Minkowski (Publ. Astron. Soc. Pac., 53:224, 1941). A handful of noteworthy examples are highlighted to illustrate a general theme: classes of supernovae that were once thought to be peculiar are later seen as logical branches of standard events. This is not always the case, however, and we discuss ASASSN-15lh as an example of a transient with an origin that remains contentious. We remark on how late-time observations at all wavelengths (radio-through-X-ray) that probe 1) the kinematic and chemical properties of the supernova ejecta and 2) the progenitor star system's mass loss in the terminal phases preceding the explosion, have often been critical in understanding the nature of seemingly unusual events.

  7. INDIVIDUAL AND PSYCHOLOGICAL PECULIARITIES OF TRANSLATING AS A LANGUAGE ABILITIES COMPONENT

    Full Text Available The article addresses the differential-psychological aspect of translating abilities as a component of language abilities. The peculiarity of translation is described including both linguistic and paralinguistic aspects of translating a content and a sense from one language into another accompanied by linguistic and cognitive actions. A variety of individual and psychological peculiarities of translation based on the translation dominant were revealed. It was demonstrated that these peculiarities are relevant to communicative and linguistic types of language abilities discovered byM.K. Kabardov. Valid assessment methods such as M.N. Borisova’s test for investigation “artistic” and “thinking” types of Higher Nervous Activity (HNA, D. Wechsler’ test of verbal and nonverbal intelligence, and a test developed by the authors of the article for individual specificity of interpreter’s activity as communicative and linguistic types of translating abilities assessment were used. The results suggest that all the typological differences are based on special human types of HNA. Subjects displaying the “thinking” type use linguistic methods when translating, whereas subjects displaying the “artistic” type try to use their own subjective life experience and extralinguistic methods when translating foreign language constructions. Extreme subjects of both types try to use the most developed components of their special abilities in order to compensate the components of the other type which are not well developed to accomplish some language tasks. In this case subjects of both types can fulfill these tasks rather successfully.

    Full Text Available Peculiarities of land market formation and peculiarities of its function in modern (up-to-date environment are covered in this article. The objective necessity of governmental regulation is shown. In authors opinion the economic regulation of land market is the most important part of the system. Economic regulation mechanism is realized in correlation with economic land evaluation. Cadastre evaluation that is applied today does not reflect the true land value, but it is used as a basis for the land rent rat estimation and the initial selling price. The alternative way of land resource evaluation that is offered in the article reflects the change of country economic situation more real and is able to influence objectively on the land relations regulation decision making process.

    2011-01-01

    In this article the peculiarities of transformation of light wave with arbitrary polarization by a half-infinity biisotropic medium and a biisotropic layer surrounded by different media are considered. Analytical expressions are obtained for refraction and reflection coefficients of transformed waves. The influence of layer parameters on refraction and reflection is investigated. It is shown that at arbitrary polarization of incident light the reflected wave is elliptically polarized. The possibility is established and the conditions are determined for π/2 turning the polarization plate of the wave at reflection from the biisotropic medium/layer. The refraction of the light wave by a plate-lake biisotropic layer is analyzed. It is grounded that the wave, transmitted the layer, is elliptically polarized, at that its ellipticity depends on chiral and non-reciprocal parameters, the non-reciprocality influence is weaker.

    Habibi, Farhang; Baghram, Shant; Tavasoli, Saeed

    Aims: In this work, we address the issue of peculiar velocity measurement in a perturbed Friedmann universe using the deviations from measured luminosity distances of standard candles from background FRW universe. We want to show and quantify the statement that in intermediate redshifts (0.5 deviations from the background FRW model are not uniquely governed by peculiar velocities. Luminosity distances are modified by gravitational lensing. We also want to indicate the importance of relativistic calculations for peculiar velocity measurement at all redshifts. Methods: For this task, we discuss the relativistic correction on luminosity distance and redshift measurement and show the contribution of each of the corrections as lensing term, peculiar velocity of the source and Sachs-Wolfe effect. Then, we use the SNe Ia sample of Union 2, to investigate the relativistic effects, we consider. Results: We show that, using the conventional peculiar velocity method, that ignores the lensing effect, will result in an overestimate of the measured peculiar velocities at intermediate redshifts. Here, we quantify this effect. We show that at low redshifts the lensing effect is negligible compare to the effect of peculiar velocity. From the observational point of view, we show that the uncertainties on luminosity of the present SNe Ia data prevent us from precise measuring the peculiar velocities even at low redshifts (z < 0.2).

    Full Text Available The article is devoted to the investigation of linguistic and cognitive aspects of irreality in English and Russian languages. Since the study of irreality in linguistic and cognitive aspects has no long history the importance is emphasized. The interrelation of the real world and mental activity resulted in irreality is revealed. The notion “irreality” is investigated and detailed. Multi-vector understanding of the notion ‘irreality’ is underlined. The investigation highlights the peculiarities of the notion ‘irreality’ verbalized by nouns in both languages. Wide nomination variety is registered. The analysis of lexical units has resulted in five types of irreality: ‘pure’ irreality, subjective substantialism, scientific substantialism, hypothetical substantialism and illogical substantialism. Suggested classification covers the whole field of irreality. Plurality of types of substantialism indicates the necessity of the research. Nouns denoting ‘pure’ irreality turned out to be the most numerous in both languages. Such conclusion reflects the attitude of the English and Russians to the analyzed notion. The prototype of irreality is not found out because of its ambiguity. Illustrative material (2000 lexical units is provided to confirm theoretical conclusions made. Quantitative information is highlighted and analyzed. Language is very sensitive to changes in everyday life of people. The appearance of different new lexical units denoting the world of irreality is the result of these changes. New innovations are witnesses of language vitality. Common and different features are reflected. The analysis of nonrelated languages permits to distinguish the cross-linguistic peculiarities and outlines the typological generalizations. This kind of approach is capable of producing further results in studying the world of irreality.

  14. Reflecting on Language from ‘Sideways-on’: Preparatory and Non-Preparatory Aspects-Seeing

    Reshef Agam-Segal

    2012-09-01

    Full Text Available Aspect-seeing, I claim, involves reflection on concepts. It involves letting oneself feel how it would be like to conceptualize something with a certain concept, without committing oneself to this conceptualization. I distinguish between two kinds of aspect-perception: 1. Preparatory: allows us to develop, criticize, and shape concepts. It involves bringing a concept to an object for the purpose of examining what would be the best way to conceptualize it. 2. Non-Preparatory: allows us to express the ingraspability of certain experiences. It involves bringing a concept to an object for the purpose of showing—per impossible—what it would take to properly capture one’s experience. I demonstrate the usefulness of the two kinds of aspect perception in making conceptual judgments, and in making moral and aesthetic judgments.

It (a) lists a few differences in sensorimotor integration between subjects with high (highs) and low (lows) hypnotizability scores in the ordinary state of consciousness and in the absence of suggestions, (b) proposes that hypnotizability-related cerebellar peculiarities may account for them, (c) suggests that the cerebellum could also be involved in cognitive aspects of hypnotizability and (d) explains why the information derived from studies of sensorimotor and cardiovascular aspects of hypnotizability may be relevant to its definition and useful in orienting further experimental research in the field of hypnosis.

  17. Ordinary or peculiar men? Comparing the customers of prostitutes with a nationally representative sample of men.

    Monto, Martin A; Milrod, Christine

    2014-07-01

    Recent media attention implies that prostitution seeking is widespread, an "ordinary" aspect of masculine sexual behavior. Other accounts suggest that customers are "peculiar," characterized by distinct qualities, perversions, or psychological impairments. Using the nationally representative General Social Survey (GSS), this study demonstrates that prostitution seeking is relatively uncommon. Only about 14% of men in the United States report having ever paid for sex, and only 1% report having done so during the previous year. Furthermore, this study dissects whether customers are ordinary or peculiar by comparing a new sample of active customers who solicit sex on the Internet with an older sample of arrested customers, a sample of customers from the GSS, and a nationally representative sample of noncustomers. The customers of Internet sexual service providers differed greatly from men in general and also from other customers. The remaining samples of customers differed slightly from noncustomers in general. We argue for a balanced perspective that recognizes the significant variety among customers. There is no evidence of a peculiar quality that differentiates customers in general from men who have not paid for sex. © The Author(s) 2013.

    Full Text Available Graham Greene's The Quiet American could be understood as the specific and unique example in experimental modern and post modern fiction during the twentieth century. This novel could be accepted as the peculiar application of the experiment what makes it almost the exceptional case in modern fiction. Greene used some innovative and usual modern elements expressing them through the prism of completely unusual experimental aspect of form. In the novel, Greene made the combination of already known innovative and usual modern elements and traditional elements of form. Actually, he covered the experimental innovations with the common thematic structure, narrative form and partly with the specific psychoanalytical presentation of character's minds, observing and expressing them all at the same time.

    This project challenges the essentialist notions of gender in fantasy genre. The trilogy of Miss Peregrine’s Peculiar Children will shed light on the shifting patterns of gender performativity in fantasy. To drive our analysis, we will resort to Judith Butler’s theory of gender performativity, Joseph Campbell’s monomyth and William Indick’s study of fantasy and myth.

  20. Radio emission in peculiar galaxies

    Demellorabaca, Dulia F.; Abraham, Zulema

    1990-01-01

    During the last decades a number of surveys of peculiar galaxies have been carried out and accurate positions become available. Since peculiarities are a possible evidence of radio emission (Wright, 1974; Sulentic, 1976; Stocke et al., 1978), the authors selected a sample of 24 peculiar galaxies with optical jet-like features or extensions in different optical catalogues, mainly the Catalogue of Southern Peculiar Galaxies and Associations (Arp and Madore, 1987) and the ESO/Uppsala Survey of the ESO(B) Atlas (Lauberts, 1982) for observation at the radio continuum frequency of 22 GHz. The sample is listed in a table. Sol (1987) studied this sample and concluded that the majority of the jet-like features seem to admit an explanation in terms of interactive galaxies with bridges and/or tails due to tidal effects. Only in a few cases do the jets seem to be possibly linked to some nuclear activity of the host galaxy. The observations were made with the 13.7m-radome enclosed Itapetinga Radiotelescope (HPBW of 4.3 arcmin), in Brazil. The receiver was a 1 GHz d.s.b. super-heterodine mixer operated in total-power mode, with a system temperature of approximately 800 K. The observational technique consisted in scans in right ascention, centralized in the optical position of the galaxy. The amplitude of one scan was 43 arcmin, and its duration time was 20 seconds. The integration time was at least 2 hours (12 ten-minute observations) and the sensibility limit adopted was an antenna temperature greater than 3 times the r.m.s. error of the baseline determination. Virgo A was used as the calibrator source. Three galaxies were detected for the first time as radio sources and four other known galaxies at low frequencies had their flux densities measured at 22 GHz. The results for these sources are presented.

    Peculiar cases of acoustic wave propagation and reflection may be observed in strongly anisotropic acousto-optical crystals. A tellurium dioxide crystal serves as a prime example of such media, since it possesses record indexes of acoustic anisotropy. We studied one of the unusual scenarios of acoustic incidence and reflection from a free crystal-vacuum boundary in paratellurite. The directions of the acoustic waves in the (001) plane of the crystal were determined, and their basic characteristics were calculated. The carried-out acousto-optic experiment at the wavelength of light 532 nm and the acoustic frequency 73 MHz confirmed the theoretical predictions. The effects examined in the paper include the acoustic wave propagation with the record walkoff angle 74°. We also observed the incidence of the wave on the boundary at the angle exceeding 90°. Finally, we registered the close-to-back reflection of acoustic energy following the incidence. One of the stunning aspects is the distribution of energy between the incident and the back-reflected wave. The unusual features of the acoustic wave reflections pointed out in the paper are valuable for their possible applications in acousto-optic devices.

    Photometric indices are used to study the broad, continuum features that are present in the energy distributions of many peculiar A stars and that may be indicators of the atmospheric structure. Values of Maitzen's Δa index, which is a measure of the lambda5200 feature, are synthesized from spectrophotometric data to examine the properties of this photometric system as well as to establish a preliminary criterion of presence for the feature. Many Ap stars definitely exhibit this feature, which normal main sequence stars lack. Two indices Δiota and Δiota* are calculated from spectrophotometry to measure the strength of the lambda4200 feature. About 90% of the Ap stars are found to have definite positive results based on the preliminary criterion of presence of the latter index. For the Ap stars there is a general tendency for Δa to increase with Δiota and Δiota*. This most likely reflects the tendency for most abundances to increase together in the Ap stars. The HgMn stars have systematically larger Δiota* and Δa values than the normal stars. This does not necessarily mean that they have the lambda4200 and lambda5200 features of the peculiar A stars. To study this question requires careful comparison of the energy distributions of the HgMn stars with those of other stars and with the predictions of model atmospheres

  6. Cosmic string induced peculiar velocities

    1987-02-01

    We calculate analytically the probability distribution for peculiar velocities on scales from 10h -1 to 60h -1 Mpc with cosmic string loops as the dominant source of primordial gravitational perturbations. We consider a range of parameters βGμ appropriate for both hot (HDM) and cold (CDM) dark matter scenarios. An Ω = 1 CDM Universe is assumed with the loops randomly placed on a smooth background. It is shown how the effects can be estimated of loops breaking up and being born with a spectrum of sizes. It is found that to obtain large scale streaming velocities of at least 400 km/s it is necessary that either a large value for βGμ or the effect of loop fissioning and production details be considerable. Specifically, for optimal CDM string parameters Gμ = 10 -6 , β = 9, h = .5, and scales of 60h -1 Mpc, the parent size spectrum must be 36 times larger than the evolved daughter spectrum to achieve peculiar velocities of at least 400 km/s with a probability of 63%. With this scenario the microwave background dipole will be less than 800 km/s with only a 10% probability. The string induced velocity spectrum is relatively flat out to scales of about 2t/sub eq//a/sub eq/ and then drops off rather quickly. The flatness is a signature of string models of galaxy formation. With HDM a larger value of βGμ is necessary for galaxy formation since accretion on small scales starts later. Hence, with HDM, the peculiar velocity spectrum will be larger on large scales and the flat region will extend to larger scales. If large scale peculiar velocities greater than 400 km/s are real then it is concluded that strings plus CDM have difficulties. The advantages of strings plus HDM in this regard will be explored in greater detail in a later paper. 27 refs., 4 figs., 1 tab

    Nanostructured magnetic materials, consisting of nanometer-sized crystallites, are currently a developing subject. Evidence has been accumulating that they possess properties that can differ substantially from those of bulk materials. This paper illustrates how Moessbauer spectroscopy can yield useful information on the structural peculiarities associated with these small particles. As illustrations, metallic iron and iron-oxide systems are considered in detail. The subjects discussed include: (1) Phase stabilities in small particles, (2) deformed or nonsymmetric atomic arrangements in small particles, and (3) peculiar magnetic structures or non-collinear spin arrangements in small magnetic oxide particles that are correlated with lower specific magnetizations as compared to the bulk values.

    The asteroid (31) Euphrosyne is the largest body of its namesake family, and it contains more than 99% of the family mass. Among large asteroid families, the Euphrosyne group is peculiar because of its quite steep size-frequency distribution (SFD), significantly depleted in large- and medium-sized asteroids (8 < D < 12 km). The current steep SFD of the Euphrosyne family has been suggested to be the result of a grazing impact in which only the farthest, smallest members failed to accrete. The Euphrosyne family is, however, also very peculiar because of its dynamics: near its center it is crossed by the ν 6 = g – g 6 linear secular resonance, and it hosts the largest population (140 bodies) of asteroids in ν 6 antialigned librating states (or Tina-like asteroids) in the main belt. In this work we investigated the orbital evolution of newly obtained members of the dynamical family, with an emphasis on its interaction with the ν 6 resonance. Because of its unique resonant configuration, large- and medium-sized asteroids tend to migrate away from the family orbital region faster than small-sized objects, which were ejected farther away from the family center. As a consequence, the SFD of the Euphrosyne family becomes steeper in time with a growing depletion in the number of the largest family members. We estimate that the current SFD could be attained from a typical, initial SFD on timescales of 500 Myr, consistent with estimates of the family age obtained with other independent methods.

The Euphrosyne family is, however, also very peculiar because of its dynamics: near its center it is crossed by the ν6 = g - g 6 linear secular resonance, and it hosts the largest population (140 bodies) of asteroids in ν6 antialigned librating states (or Tina-like asteroids) in the main belt. In this work we investigated the orbital evolution of newly obtained members of the dynamical family, with an emphasis on its interaction with the ν6 resonance. Because of its unique resonant configuration, large- and medium-sized asteroids tend to migrate away from the family orbital region faster than small-sized objects, which were ejected farther away from the family center. As a consequence, the SFD of the Euphrosyne family becomes steeper in time with a growing depletion in the number of the largest family members. We estimate that the current SFD could be attained from a typical, initial SFD on timescales of 500 Myr, consistent with estimates of the family age obtained with other independent methods.

    The asteroid (31) Euphrosyne is the largest body of its namesake family, and it contains more than 99% of the family mass. Among large asteroid families, the Euphrosyne group is peculiar because of its quite steep size-frequency distribution (SFD), significantly depleted in large- and medium-sized asteroids (8 < D < 12 km). The current steep SFD of the Euphrosyne family has been suggested to be the result of a grazing impact in which only the farthest, smallest members failed to accrete. The Euphrosyne family is, however, also very peculiar because of its dynamics: near its center it is crossed by the ν{sub 6} = g – g {sub 6} linear secular resonance, and it hosts the largest population (140 bodies) of asteroids in ν{sub 6} antialigned librating states (or Tina-like asteroids) in the main belt. In this work we investigated the orbital evolution of newly obtained members of the dynamical family, with an emphasis on its interaction with the ν{sub 6} resonance. Because of its unique resonant configuration, large- and medium-sized asteroids tend to migrate away from the family orbital region faster than small-sized objects, which were ejected farther away from the family center. As a consequence, the SFD of the Euphrosyne family becomes steeper in time with a growing depletion in the number of the largest family members.

In common clinical aspect there was a correlation between the migraine-attack and the slight head trauma in all patients. Attack symptoms were almost identical: hemiparesis, aphasia, ataxia. The family history for migraine was burdened in both girls. A genetic testing in the boy and in the smallest girl demonstrated CACNA1A gene mutation, in the teen girl — ATP1A2 gene mutation. The electroencephalograms in all patients during the acute phase presented signs of hemipcortical brain dysfunction. The magnetic resonance imaging revealed prominent but reversible hemicortical oedema. The repeated MRI studies diagnosed nonrelevant for this disease hemicortical atrophy (girl 2 years and atrophy of the cerebellum (the boy. Due to the rarity of the disease so far there are no clear guidelines for its treatment and prevention. In view of the pathogenesis for the prevention patients were prescribed medications changing the activity of cytoplasmic calcium and sodium canals.

    Peculiar flavor may be induced from irradiative preservation of meat with higher dose. The study on the irradiation of dried duck indicated that peculiar flavor is produced by a threshold of 1.5 kGy and intensifies with the increase of dose. The flavor primarily comes from muscle of dried duck especially from its water soluble protein. With the increase of dose, volatile carbonyl compounds, amines and sulfur compounds increased significantly. Paper chromatography analysis shows that two new volatile carbonyl compounds (R f =0.23 and 0.28) and a new volatile amine-propamine are induced by irradiation. This compounds may be the source of peculiar flavor in irradiated dried duck

  4. The peculiar velocities of rich clusters in the hot and cold dark matter scenarios

    1993-01-01

    We present the results of a study of the peculiar velocities of rich clusters of galaxies. The peculiar motion of rich clusters in various cosmological scenarios is of interest for a number of reasons. Observationally, one can measure the peculiar motion of clusters to greater distances than galaxies because cluster peculiar motions can be determined to greater accuracy. One can also test the slope of distance indicator relations using clusters to see if galaxy properties vary with environment. We have used N-body simulations to measure the amplitude and rms cluster peculiar velocity as a function of bias parameter in the hot and cold dark matter scenarios. In addition to measuring the mean and rms peculiar velocity of clusters in the two models, we determined whether the peculiar velocity vector of a given cluster is well aligned with the gravity vector due to all the particles in the simulation and the gravity vector due to the particles present only in the clusters. We have investigated the peculiar velocities of rich clusters of galaxies in the cold dark matter and hot dark matter galaxy formation scenarios. We have derived peculiar velocities and associated errors for the scenarios using four values of the bias parameter ranging from b = 1 to b = 2.5. The growth of the mean peculiar velocity with scale factor has been determined and compared to that predicted by linear theory. In addition, we have compared the orientation of force and velocity in these simulations to see if a program such as that proposed by Bertschinger and Dekel (1989) for elliptical galaxy peculiar motions can be applied to clusters. The method they describe enables one to recover the density field from large scale redshift distance samples. The method makes it possible to do this when only radial velocities are known by assuming that the velocity field is curl free. Our analysis suggests that this program if applied to clusters is only realizable for models with a low value of the bias

    We present a new photometric identification technique for SN 1991bg-like type Ia supernovae (SNe Ia), i.e., objects with light curve characteristics such as later primary maxima and the absence of a secondary peak in redder filters. This method is capable of selecting this sub-group from the normal type Ia population. Furthermore, we find that recently identified peculiar sub-types such as SNe Iax and super-Chandrasekhar SNe Ia have photometric characteristics similar to 91bg-like SNe Ia, namely, the absence of secondary maxima and shoulders at longer wavelengths, and can also be classified with our technique. The similarity of these different SN Ia sub-groups perhaps suggests common physical conditions. This typing methodology permits the photometric identification of peculiar SNe Ia in large upcoming wide-field surveys either to study them further or to obtain a pure sample of normal SNe Ia for cosmological studies.

    1977-01-01

    Expected numbers of elliptical galaxies distorted tidally in the Coma cluster are formulated in terms of the various parameters of the cluster, and of cross section of galaxy-galaxy encounters and duration of associated tidal distributions. For the latter two quantities, numerical computations are carried out by simulating elliptical galaxies with hundreds of test particles. Comparisons are made with the number of peculiar galaxies observed in the Coma cluster. The hypothesis that the ''missing mass'' of the Coma cluster is hidden in the form of invisible galaxies or huge black holes of ordinary galaxy masses is also tested. It is concluded that tidal interaction between the visible galaxies plays only a minor role in the origin of the peculiar galaxies in the Coma cluster. Most of them would be due to their individual non-tidal mechanisms. If invisible galaxies or massive black holes are assumed as cluster members, their encounters with the luminous members increase the frequency of observable tidal distortion, and approximately half of the number of the peculiar galaxies could be explained in terms of tidal interaction. This result is discussed in relation to some special types of the peculiar galaxies in the Coma cluster. (auth.)

    Alonso, M. V.

    Se presenta un resumen de los resultados más importantes obtenidos en los últimos años sobre movimientos peculiares en el Universo Cercano. En el escenario de inestabilidad gravitacional, el campo de velocidades peculiares es una herramienta muy útil para estimar las fluctuaciones en la distribución de masa que generan los movimientos observados. Esta aproximación puede, además, ser utilizada para poner restricciones al espectro de potencia de la masa, a la relación entre las distribuciones de galaxias y de materia y al valor del parámetro de densidad cosmológico, Ω, a grandes escalas. Son además presentados una reconstrucción preliminar de los campos de densidad de masa y velocidades peculiares en el universo cercano usando nuevas medidas de distancias obtenidas con la relación Dn - σ, para una muestra de galaxias elípticas y lenticulares. Dos subestructuras prominentes son encontradas en la región del Gran Atractor, que corresponden a los complejos de Centaurus y Pavo--Indus. Estos últimos, junto a los complejos de Perseus--Piscis y Cetus parecen ser importantes estructuras que determinan el flujo global. El patrón obtenido a través de una muestra de galaxias elípticas muestra variaciones con respecto al obtenido por galaxias espirales. Estos nuevos resultados muestran una coherencia menor en el flujo global, cuando son comparados con resultados obtenidos anteriormente.

    The characteristic peculiarities of the self-reflection of a strong electromagnetic wave in a system of coherent excitons and biexcitons due to the exciton-photon interaction and optical exciton-biexciton conversion in semiconductors were investigated as one of the manifestations of nonlinear optical Stark-effect. It was found that a monotonously decreasing standing wave with an exponential decreasing spatial tail is formed in the semiconductor. Under the action of the field of a strong pulse, an optically homogeneous medium is converted, into the medium with distributed feedback. The appearance of the spatially separated narrow pears of the reflective index, extinction and reflection coefficients is predicted.

    Internet grows to everyday practice of objective reality of average Ukrainians. Internet actively builds up its social influence on society and turns to be such a social environment which like barometer reflects social and political situation in the country and determines integration processes in Ukrainian society. Ukrainians consider Internet at present time as potential resource to realize social and civil activity, the resource which makes it possible to impact on power structures and to control power by citizens. Still the social and civil practices in Internet have not become the everyday practice of average Ukrainians. This outcome is caused because of Ukrainians assess their ability too low as regards the impact on power as well as objective reasons of internet technologies development in modern society. The Internet democracy development has still young history of its emerge and social development. E-government, provision of e-services by e-governments, e-interaction of different social objects today, all of those things have just begun to grow and to win out their rights for existing in full value in the society. Undoubtedly, all of those peculiarities affect the special features of citizens’ participation in Internet in modern word. Such development needs the formation of public culture how to utilize the net and certain experience and skills to implement such interaction.

    Unique palaeogeographical peculiarities of sedimentary formations are important for geological heritage conservation and use for the purposes of tourism. The heritage value of the Pabdeh Formation (Paleocene-Oligocene) of the Zagros Fold-Thrust Belt in Iran has been investigated. The uniqueness of its palaeogeographical peculiarities has been assessed on the basis of the literature, field studies of three representative sections in the Fars Province (Kavar, Zanjiran, and Shahneshin sections), and comparison with the similar features known in Iran and globally. The Pabdeh Formation reflects the process of mixed siliciclastic-carbonate ramp progradation and the onset of a typical carbonate platform. The other unique features include representation of mesopelagic palaeohabitat, specific trace fossil assemblages, prehistoric bituminous artefacts (production of which was linked to the Pabdeh deposits), etc. It is established that the palaeogeographical type of geological heritage of the Pabdeh Formation is represented by all known subtypes, namely facies, palaeoecosystem, ichnological, taphonomical, event, and geoarchaeological subtypes. Their rank varies between regional and global. The very fact of co-occurrence of these subtypes determines the global importance of the entire palaeogeographical type in the case of this formation. The establishment of geopark in the Zagros Fold-Thrust Belt will facilitate adequate use of the Pabdeh Formation for the purpose of geotourism development. The aesthetic properties (rocks of different colour and striped patterns of outcrops) increase the attractiveness of this geological body to visitors.

    Full Text Available Teaching is a complex profession, which is further complicated by the integration of technology into classrooms. Reflection can help teachers unpack the complexity in their practice. Reflection can be an effective instructional strategy in helping preservice teachers develop technological pedagogical content knowledge (TPACK, the complex and dynamic knowledge necessary for effective technology integration into instruction. In this study, reflective activities were integrated into a Learning By Design (LBD environment, which was created to help preservice teachers develop TPACK. This paper investigated the participants’ TPACK development and examined how reflection helped them construct TPACK. Through content analysis of the participants’ reflective journals, the researcher found that the preservice teachers developed initial TPACK awareness. However, their reflection in technology knowledge and the content aspects of TPACK were limited and superficial. Interviews with the participants showed reflection helped the preservice teachers remember what they learned by describing and elaborating on their in-class experiences, pushed them to think about how to apply what they learned in their future classrooms, and helped them become more reflective and open-minded about using technology in classrooms. Finally, the researcher discussed this study’s implications for teacher educators and researchers.

    2013-01-01

    Full Text Available This study presents transient aspects of light wave propagation connected with spatial coherence. It is shown that reflection and refraction phenomena involve spatial patterns which are created within a certain transient time interval. After this transient time interval, these patterns act like a memory, determining the wave vector for subsequent sets of reflected/refracted waves. The validity of this model is based on intuitive aspects regarding phase conservation of energy for waves reflected/refracted by multiple centers in a certain material medium.

For all of these effects we present a case study showing the impact on the cosmology derived by the Sloan Digital Sky Survey-II Supernova Survey (SDSS-II SN Survey). Correcting supernova (SN) redshifts for the cosmic microwave background (CMB) dipole slightly overcorrects...... nearby SNe that share some of our local motion. We show that while neglecting the CMB dipole would cause a shift in the derived equation of state of ¿w ~ 0.04 (at fixed O m ), the additional local-motion correction is currently negligible (¿w

    Dixneuf, Sophie; Rachet, Florent; Chrysos, Michael

    2015-01-01

    Owing in part to the p orbitals of its filled L shell, neon has repeatedly come on stage for its peculiar properties. In the context of collision-induced Raman spectroscopy, in particular, we have shown, in a brief report published a few years ago [M. Chrysos et al., Phys. Rev. A 80, 054701 (2009)], that the room-temperature anisotropic Raman lineshape of Ne–Ne exhibits, in the far wing of the spectrum, a peculiar structure with an aspect other than a smooth wing (on a logarithmic plot) which contrasts with any of the existing studies, and whose explanation lies in the distinct way in which overlap and exchange interactions interfere with the classical electrostatic ones in making the polarizability anisotropy, α ∥ − α ⊥ . Here, we delve deeper into that study by reporting data for that spectrum up to 450 cm −1 and for even- and odd-order spectral moments up to M 6 , as well as quantum lineshapes, generated from SCF, CCSD, and CCSD(T) models for α ∥ − α ⊥ , which are critically compared with the experiment. On account of the knowledge of the spectrum over the augmented frequency domain, we show how the inverse scattering problem can be tackled both effectively and economically, and we report an analytic function for the anisotropy whose quantum lineshape faithfully reproduces our observations

    Superimposed on the continuous Schumann resonance (SR) background in the extremely low frequency (ELF) band, transient signals (e.g. bursts) can be observed, which originate from intense lightning discharges occurring at different locations on the globe. From the many transients that were observed at the Astronomical and Geophysical Observatory (AGO) of Comenius University near Modra, western Slovakia, in the vertical electric field component mainly during May and June of 2006, a peculiar group of events could be recognized. According to the waveform analysis, these peculiar events in most cases consist of two overlapping transients with a characteristic time difference of 0.13-0.15 s between the onsets. On the other hand, the spectrum of these peculiar transients showed discernible SR peaks for higher modes as well (n>7). The same events could be found in the records of the Széchenyi István Geophysical Observatory of the Geodetic and Geophysical Research Institute of the Hungarian Academy of Sciences near Nagycenk, Hungary (NCK). The natural origin of the peculiar events was verified from the NCK data and the source location was determined from the second transient. The results suggest that the two consecutive transients originated in the same thunderstorm. Furthermore, the phase spectrum analysis indicates that the sources have coherently excited the Earth-ionosphere cavity. These findings seem to support the idea that electromagnetic waves orbiting the Earth might trigger lightning discharges. The possibility that electromagnetic waves may trigger discharges was first considered by Nikola Tesla.

  12. From the Love of God to the God-Love: Reflections on an Unamunian Problem

    Directory of Open Access Journals (Sweden)

    Antonio M. López Molina

    2014-11-01

    Full Text Available The central thesis of this paper is as follows: Unamuno’s genuine concept of God, namely,the biotic God, the cordial God, the God-Love, is the result of the convergence of three philosophical traditions in which Unamuno introduces a peculiar change. The first is Unamuno’s critique of ScholasticTheology and its conception of God as ens realissimum, First Cause or Prime Mover. The second can be found in the Augustinian-Lutheran-Kierkegaardian tradition and its call to the inner world, personality and individuality. And finally, engaging in a peculiar reflection activity that allows him to join the intellectualist and voluntarist traditions, the philosopher of Salamanca turns to the atheistic philosophy of Schopenhauer,who presents a world as will, pain and compassion. A new conception of God based on will, faith and hope emerges because of the critique and transformation of these philosophies.

    Full Text Available Induction or search-coil magnetometers (IM are widely used in many branches of science and industry. The frequency range and dynamic range of IMs are probably the widest of all existing magnetometers: they are used for the measurement of magnetic field variations in the frequency band from ~10-4 till ~106 Hz with the intensities from fractions of femtotesla till tens of tesla. This explains the permanent interest to IM design and the attempts to construct the IMs with best possible parameters. The present paper deals with the peculiarities of IM design. An attempt to re-establish the correctness of priorities in the field is made and the approaches to the IM optimization and their quality estimation are described.

    For the DRS measurements of skin benign, dysplastic and malignant lesions in vivo we applied halogen lamp (LS-1, OceanOptics Inc, Dunedin, Fl, USA) as a continuous light source in the region of 400-900 nm, optical probe (6+1 fibers) for the delivery of illumination and diffuse reflected light from the skin investigated and microspectrometer USB4000 (OceanOptics Inc., Dunedin, Fl, USA) for a storage and display of the spectra detected. As a diffuse reflectance standard Spectralon® plate was used to calibrate the spectrometer. The reflectance spectra obtained from normal skin in identical anatomic sites of different patients have similar spectral shape features, slightly differ by the reflectance intensity at different wavelengths, depending on the particular patient' skin phototype. One could find diagnostically important spectral features, related to specific intensity changes for a given wavelength due to specific pigments appearance, slope changes by value and sign for the reflectance spectra curves in a specific spectral range, disappearance or manifestation of minima, related to hemoglobin absorption at 410-420 nm, 543, 575 nm. Based on the observed peculiarities multispectral analysis of the reflectance spectra of the different lesions was used and diagnostically specific features are found. Discrimination using the DRS data obtained between benign compound and dermal nevi (45 cases), dysplastic nevi (17 cases) and pigmented malignant melanoma (41 cases) lesions is achieved with a diagnostic accuracy of 96 % for the benign nevi vs. MM, and 90 % for the dysplastic nevi vs. MM.

    2018-01-01

    The nature of science has been part of Thailand's science education curriculum since 2008. However, teachers lack of understanding about the nature of science (NOS) and its teaching, particularly element school science teachers. In 2012, the Science Institute of Thailand MOE, started a project of Elementary Science Teacher Professional Development to enhance their thinking about the Nature of Science. The project aimed to enhance teachers' understanding of NOS, science teaching for explicit and reflective NOS, with the aim of extending their understanding of NOS to other teachers. This project selected 366 educational persons. The group was made up of a teacher and a teacher supervisor from 183 educational areas in 74 provinces all Thailand. The project provided a one week workshop and a year's follow up. The week-long workshop consisted of 11 activities of science teaching for explicit reflection on 8 aspects of NOS. Workshop of NOS explicit and reflective on force and motion learning activity is one of eight activities. This activity provided participants to learn force and motion and NOS from the traditional toy "Bang-Poh". The activity tried to enhance participants to explicit NOS for 5 aspects including empirical basis, subjectivity, creativity, observation and inference, and sociocultural embeddedness. The explicit NOS worksheet provided questions to ask participants to reflect their existing ideas about NOS. The paper examines elementary school science teachers' understanding of NOS from the force and motion learning activity which provided explicit reflection on 5 NOS aspects. An interpretive paradigm was used to analyse the teachers' reflections in a NOS worksheet. The findings indicated that majority of them could reflect about the empirical basis of science and creativity but few reflected on observation and inference, or sociocultural embeddedness. The paper will explain the teachers' NOS thinking and discuss the further enhancing of their understanding

    Generating language that reflects the temporal organization of represented knowledge requires a language generation model that integrates contemporary theories of tense and aspect, temporal representations, and methods to plan text. This paper presents a model that produces complex sentences that reflect temporal relations present in underlying temporal concepts. The main result of this work is the successful application of constrained linguistic theories of tense and aspect to a generator which produces meaningful event combinations and selects appropriate connecting words that relate them.

    1993-01-01

    An assessment is made of the safety aspects peculiar to using the Particle Bed Reactor (PBR) as the burner in a plutonium disposal system. It is found that a combination of the graphitic fuel, high power density possible with the PBR and engineered design features results in an attractive concept. The high power density potentially makes it possible to complete the plutonium burning without requiring reprocessing and remanufacturing fuel. This possibility removes two hazardous steps from a plutonium burning complex. Finally, two backup cooling systems depending on thermo-electric converters and heat pipes act as ultimate heat removal sinks in the event of accident scenarios which result in loss of fuel cooling

    Tan, L H

    2004-07-01

    This review revisits Waldeyer's ring lymphomas as classified by the World Health Organisation. Sources of data include international studies on Waldeyer's ring lymphomas as well as from personal observations gleaned from lymphoma statistics of Singapore General Hospital, Changi General Hospital, Tan Tock Seng Hospital and National University Hospital within the last decade or so. Waldeyer's ring shares many of the histopathological trends of the rest of mucosa-associated lymphoid tissue (MALT), such as the high frequency of diffuse large B-cell lymphomas, and the relative rarity of follicular lymphomas in spite of its rich endowment with reactive lymphoid follicles. However, extranodal marginal zone lymphoma or "MALToma" may not be as frequently encountered as in other mucosal sites. Furthermore, the placement of Waldeyer's ring is unique in that stark comparisons with the lymphopathology of the immediately anterior oronasal cavities can be made, with intriguing peculiarities such as the abrupt reversal of the ratio of B-cell to T/NK-cell lymphoma frequency upon crossing the imaginary line that separates the 2 regions. The differential diagnosis with regionally common lymphoma mimics, in particular reactive parafollicular hyperplasia and nasopharyngeal undifferentiated (lymphoepithelial) carcinoma of Schmincke pattern, both often aetiologically related to Epstein-Barr viral infection, is also discussed. Recognition of the peculiarities and patterns of Waldeyer's ring lymphomas is important for accurate pathologic assessment. Postulates that attempt to account for the patterns and peculiarities of Waldeyer's ring lymphopathology can be used to direct further research.

    Full Text Available Comparative research concerning masticatory musculature in squirrel, muskrat and rabbit, take into account the emphasizing and morphofunctional interpretation of the osteomuscular particularities involved in the prehension and mastication processes. The development of the coronoid process on the muskrat and squirrel demonstrates the growing of the force when raising the mandible by increasing the action force attached to the temporal muscle, with insertion on the coronoid process. In comparison with that, in the case of rabbits, both the coronoid process and the temporal muscle are reduced. From a philogenetic point of view, it has been found that the species that have the articular condyle lowered at or under the level of the dental tables (carnivores present a greater pressure force between the dental tables. Analyzing this aspect of the rodents taken into discussion, we noticed the lowering of the articular condyle up to the inferior molars' plane, in the case of squirrels and muskrats, but through obliquity, namely through cranial caudal and dorsoventral movement. This peculiarity is emphasized through the analysis of the angle formed by the axis of the mandible recurved branch (passing through the mandibular condyle with the axis of the horizontal branch of the mandible, where it was noticed that along with the increase in the angle formed by the two axes, which becomes an obtuse 160 degree angle on the squirrel and 130 degrees on the muskrat, there is also a lowering of the articular condyle up to the molar level, while in the case of carnivores, the lowering of the condyle is done without the modification of the angle between the two axes, which measures approximately 90 degrees.

    Vittorio, N.; Turner, M.S.

    1986-10-01

    The inflationary Universe scenario predicts a flat Universe and both adiabatic and isocurvature primordial density perturbations with the Zel'dovich spectrum. The two simplest realizations, models dominated by hot or cold dark matter, seem to be in conflict with observations. Flat models are examined with two components of mass density, where one of the components of mass density is smoothly distributed and the large-scale (≥10h -1 MpC) peculiar velocity field for these models is considered. For the smooth component relativistic particles, a relic cosmological term, and light strings are considered. At present the observational situation is unsettled; but, in principle, the large-scale peculiar velocity field is very powerful discriminator between these different models. 61 refs

    2017-12-01

    Full Text Available Contract formation by electronic means nowadays is a widespread phenomenon. Nevertheless electronic contracting has been thoroughly explored by scholars all over the world and regulated both internationally and domestically, there still remain some issues which need to be carefully analyzed. In our view, the most essential question raised by electronic contracting is whether there is a need to amend substantial contract law provisions with regard to peculiarities of contracts concluded by electronic means. Seeking the answer to this question several approaches have been formulated, but none of them seems to be completely appropriate. In this paper the answer is also attempted to be found. For this purpose a comparative analysis of doctrine, legislation and judicial practice of certain states is performed. Particularly, offer, acceptance and moment of electronic contract formation are explored. On the basis of this research the following conclusion is done: amendments to substantial contract law provisions are not always necessary to improve the regulation of electronic contracting. Nevertheless the provisions of law should be applied correctly to the disputes arising from electronic contract formation taking into account the peculiarities of such contracts.

    We have conducted a differential elemental abundance analysis of unprecedented accuracy (∼0.01 dex) of the Sun relative to 11 solar twins from the Hipparcos catalog and 10 solar analogs from planet searches. We find that the Sun shows a characteristic signature with a ∼20% depletion of refractory elements relative to the volatile elements in comparison with the solar twins. The abundance differences correlate strongly with the condensation temperatures of the elements. This peculiarity also holds in comparisons with solar analogs known to have close-in giant planets while the majority of solar analogs found not to have such giant planets in radial velocity monitoring show the solar abundance pattern. We discuss various explanations for this peculiarity, including the possibility that the differences in abundance patterns are related to the formation of planetary systems like our own, in particular to the existence of terrestrial planets.

    Objective This paper describes a reflective learning program within a larger curriculum on behavioral and social science that makes use of close reading, written representation of experience, discussion, and textual response. This response may in turn lead to further reflection, representation, and response in a circular pattern. A unique feature of this program is that it pays attention to the representation itself as the pivotal activity within reflective learning. Using the narrative methods that are the hallmark of this program, faculty writings were analyzed to characterize the essential benefits that derive from these practices. Methods In the context of a faculty development seminar on the teaching of behavioral and social sciences in medical curricula, a group of fifteen faculty members wrote brief narratives of reflective learning experiences in which they had made use of the methods described above. Their responses were submitted to iterative close reading and discussion, and potential themes were identified. Results Four themes emerged: writing as attention to self, writing as attention to other, writing as reader/writer contract, and writing as discovery. In each instance, writing provides a new or deepened perspective, and in each case the dividends for the writer are amplified by the narrative skills of those who read, listen, and respond. Conclusions The narrative pedagogy described and modeled herein provides a potentially promising approach to teaching the social, cultural, behavioral, and interpersonal aspects of medical education and practice. Future research will deepen our understanding of the benefits and limitations of this pedagogy and expand our appreciation of its applications. PMID:25272952

    The Nainital-Cape Survey is a dedicated search programme initiated in 1999 in the coordination of astronomers from SAAO South Africa, ARIES Nainital and ISRO Bangalore. Over the last 17 years a total of 345 chemically peculiar stars were monitored for photometric variability, making it one of the longest ground-based survey to search for pulsation in chemically peculiar stars in terms of both time span and sample size. Under this survey, we discovered rapid pulsation in the Ap star HD12098 while δ Scuti-type pulsations were detected in seven Am stars. Those stars in which pulsations were not detected have also been tabulated along with their detailed astrophysical parameters for further investigation.

  1. Self-rumination, self-reflection, and depression: self-rumination counteracts the adaptive effect of self-reflection.

    Science.gov (United States)

    Takano, Keisuke; Tanno, Yoshihiko

    2009-03-01

    Self-focused attention has adaptive and maladaptive aspects: self-reflection and self-rumination [Trapnell, P. D., & Campbell, J. D. (1999). Private self-consciousness and the Five-Factor Model of personality: distinguishing rumination from reflection. Journal of Personality and Social Psychology, 76, 284-304]. Although reflection is thought to be associated with problem solving and the promotion of mental health, previous researches have shown that reflection does not always have an adaptive effect on depression. Authors have examined the causes behind this inconsistency by modeling the relationships among self-reflection, self-rumination, and depression. One hundred and eleven undergraduates (91 men and 20 women) participated in a two-time point assessment with a 3-week interval. Statistical analysis with structural equation modeling showed that self-reflection significantly predicted self-rumination, whereas self-rumination did not predict self-reflection. With regard to depression, self-reflection was associated with a lower level of depression; self-rumination, with a higher level of depression. The total effect of self-reflection on depression was almost zero. This result indicates that self-reflection per se has an adaptive effect, which is canceled out by the maladaptive effect of self-rumination, because reflectors are likely to ruminate and reflect simultaneously.

    U, B, V, J, H, K photometry, polarimetry and spectroscopy of this peculiar object was made from August 1979 to December 1980 and the observations are briefly discussed. The authors consider PU Vul to be binary with a late M giant and a component of probably low luminosity. The latter flared in 1979, and the former also changed a little. From the photometric, spectroscopic and polarimetric data they estimate E(B-V) <= 0.4 and locate the star at 5-7 kpc from the sun and 0.7-1.0 kpc from the galactic plane. The photometric behaviour, duplicity, and nature of the components are similar to those of novae and symbiotic stars, but no evidence for an ejected envelope is seen. (Auth.)

Considering the repercussions that this chronic disease may cause, this study aims at performing a bibliographic survey with data that can give a subsidy to reflections on the emotional aspects experienced by the diabetic children. The findings showed that the emotional aspect influences the diabetes etiology and that the diabetes also influences the emotional aspect of this child. This is due to both the incessant cares used to control the disease and fear of possible complications, as well as to the indisposition caused by the hyper and hypoglycemia symptoms and the fact of being "different". Therefore, it is necessary an attendance of these children diabetes, not only by the doctors, but also by other health professionals, among them, the psychologist, aiming at the elaboration of the aspects related to the disease and its emotional repercussions.

    A search for a white dwarf companions of cool stars with peculiar element abundances was undertaken. One additional star the xi Cet, was found with a white dwarf companion. It was found that HR 1016, 56Uma, 16 Ser, have high excitation emission lines which indicate a high temperature object in the system. It is suggested that since these indications for high temperature companions were seen for all nearby Ba stars, it is highly probable that all Ba stars have white dwarf companions, and that the peculiar element abundances seen in the Ba stars are due to mass transfer. Observations, arguments and conclusions are presented. White dwarf companions were not found. Together with the Li and Be abundances and the chromospheric emission line spectra in these stars were studied. No white dwarf companions were seen for subgiant CH stars.

    The study of chemically peculiar (CP) stars in open clusters provides valuable information about their evolutionary status. Their detection can be performed using the Δa photometric system, which maps a characteristic flux depression at λ ∼ 5200 Å. This paper aims at studying the occurrence of CP stars in the earliest stages of evolution of a stellar population by applying this technique to Hogg 16, a very young Galactic open cluster ( ∼ 25 Myr). We identified several peculiar candidates: two B-type stars with a negative Δa index (CD - 60 4701, CPD - 60 4706) are likely emission-line (Be) stars, even though spectral measurements are necessary for a proper classification of the second one; a third object (CD - 60 4703), identified as a Be candidate in literature, appears to be a background B-type supergiant with no significant Δa index, which does not rule out the possibility that it is indeed peculiar as the normality line of Δa for supergiants has not been studied in detail yet. A fourth object (CD - 60 4699) appears to be a magnetic CP star of 8 M⊙, but obtained spectral data seem to rule out this hypothesis. Three more magnetic CP star candidates are found in the domain of early F-type stars. One is a probable nonmember and close to the border of significance, but the other two are probably pre-main sequence cluster objects. This is very promising, as it can lead to very strong constraints to the diffusion theory. Finally, we derived the fundamental parameters of Hogg 16 and provide for the first time an estimate of its metal content.

    The frequency dependence of the reflection coefficient of MgF 2 crystal in the frequency range of 200-800 cm -1 at different orientations of the optical axis has been investigated. The experimental data are compared with the calculation results. This comparison confirms that the wave vectors for the extraordinary wave have an open surface. This makes it possible to focus a divergent beam refracted at a flat boundary ori- ented perpendicularly to the optical crystal axis. The focusing effect of a plane-parallel MgF 2 crystal plate is calculated.

    Utilizing our all-sky survey of spiral galaxies, we have derived a basic description of the extragalactic peculiar velocity field. In agreement with the results of previous authors, highly significant dipole and quadrupole terms are found. These are interpreted using a number of physically simple, but plausible models. No single attractor is able to explain all of the motions observed in nearby galaxies, but the region surrounding the Centaurus cluster appears to have the dominant effect. (author)

    2015-11-01

    Full Text Available Verb aspect, alternations and quantification In this paper we are briefly discuss the nature of Bulgarian verb aspect and argue that the verb aspect pairs are different lexical units with different (although related meaning, different argument structure (reflecting categories, explicitness and referential status of arguments and different sets of semantic and syntactic alternations. The verb prefixes resulting in perfective verbs derivation in some cases can be interpreted as lexical quantifiers as well. Thus the Bulgarian verb aspect is related (in different way both with the potential for the generation of alternations and with the prefixal lexical quantification. It is shown that the scope of the lexical quantification by means of verbal prefixes is the quantified verb phrase and the scope remains constant in all derived alternations. The paper concerns the basic issues of these complex problems, while the detailed description of the conditions satisfying particular alternation or particular lexical quantification are subject of a more detailed study.

  1. Thinking and writing at Masters level: a reflective passage.

    Science.gov (United States)

    Fowler, John

    This article identifies key characteristics of Masters level writing and the underpinning relationship of these characteristics to reflective thought. Classical models of reflective writing are reviewed and their focus on reflection as a progressive process is debated. A linear model of reflection is proposed and its application to reflective writing for Masters level assessments is examined. The classical authors tend to present reflection as a process in which the outcomes of reflection becomes deeper at advanced levels. While this is an appropriate application of the concept of reflection for the traditional academic essay, it might not always be so appropriate for other more applied aspects of thinking and writing particularly in the development of advanced nursing practice. A linear model of reflective writing which offers a more pragmatic perspective on reflection is developed.

    Wegner, Gary; Cowley, Charles R.

    1992-01-01

    Ground-based high-dispersion photographic spectra and ultraviolet spectra obtained with the IUE satellite are described and employed to determine the nature of the peculiar star HR 6560 (HD 159870). Previously this object had been described as both a composite system and as a strong Fm star. The UBVRI, Stromgren, and ultraviolet colors of HR 6560 are compared with objects classified composite from the Bright Star Catalogue and normal dwarfs and giants. The colors of HR 6560 are not unusual for a composite and are consistent with a late-A dwarf, combined with a late-G or early-K giant. The ultraviolet satellite clearly shows the presence of an A component, but its precise spectral type is difficult to assign. The IUE and TD-1 data suggest that the ultraviolet is dominated by light from an A5 V secondary and the visual from a GO III primary. This does not agree well with the most plausible model that fits the visual photometry. The peculiar nature of HR 6560's spectrum is most likely due to its composite nature.

The classification is based on wide (1.2 mm) spectra of two reciprocal dispersions (39, 128 A mm -1 ) obtained with the Kitt Peak 2.1 m and 90 cm reflectors respectively. The higher dispersion is necessary to show the subtle peculiarities found in some stars. The clusters are the Orion Nebula cluster, Orion OB1 association, Lacerta OB1 association, IC 2602, IC 4665, Pleiades, M39, M34, NGC 2516, NGC 6633, NGC 6475, and Coma. (Auth.)

    We present extensive u{prime}g{prime}r{prime}i{prime} BV RIY JHK{sub s} photometry and optical spectroscopy of SN 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002cx, which has been called 'the most peculiar known type Ia supernova'. Both supernovae exhibited high ionization SN 1991T-like pre-maximum spectra, yet low peak luminosities like SN 1991bg. The spectra reveal that SN 2005hk, like SN 2002cx, exhibited expansion velocities that were roughly half those of typical type Ia supernovae. The R and I light curves of both supernovae were also peculiar in not displaying the secondary maximum observed for normal type Ia supernovae. Our Y JH photometry of SN 2005hk reveals the same peculiarity in the near-infrared. By combining our optical and near-infrared photometry of SN 2005hk with published ultraviolet light curves obtained with the Swift satellite, we are able to construct a bolometric light curve from {approx} 10 days before to {approx}60 days after B maximum. The shape and unusually low peak luminosity of this light curve, plus the low expansion velocities and absence of a secondary maximum at red and near-infrared wavelengths, are all in reasonable agreement with model calculations of a 3D deflagration which produces {approx} 0.25 M{sub {circle_dot}} of {sup 56}Ni.

  7. Neutron reflectivity

    Directory of Open Access Journals (Sweden)

    Cousin Fabrice

    2015-01-01

    Full Text Available The specular neutron reflectivity is a technique enabling the measurement of neutron scattering length density profile perpendicular to the plane of a surface or an interface, and thereby the profile of chemical composition. The characteristic sizes that are probed range from around 5 Å up 5000 Å. It is a scattering technique that averages information on the entire surface and it is therefore not possible to obtain information within the plane of the interface. The specific properties of neutrons (possibility of tuning the contrast by isotopic substitution, sensitivity to magnetism, negligible absorption, low energy of the incident neutrons makes it particularly interesting in the fields of soft matter, biophysics and magnetic thin films. This course is a basic introduction to the technique and does not address the magnetic reflectivity. It is composed of three parts describing respectively its principle and its formalism, the experimental aspects of the method (spectrometers, samples and two examples related to the materials for energy.

  8. THE PECULIAR CHEMICAL INVENTORY OF NGC 2419: AN EXTREME OUTER HALO 'GLOBULAR CLUSTER'

    Cohen, Judith G.; Kirby, Evan N.; Huang Wenjin

    2011-01-01

    NGC 2419 is a massive outer halo Galactic globular cluster (GC) whose stars have previously been shown to have somewhat peculiar abundance patterns. We have observed seven luminous giants that are members of NGC 2419 with Keck/HIRES at reasonable signal-to-noise ratio. One of these giants is very peculiar, with an extremely low [Mg/Fe] and high [K/Fe] but normal abundances of most other elements. The abundance pattern does not match the nucleosynthetic yields of any supernova model. The other six stars show abundance ratios typical of inner halo Galactic GCs, represented here by a sample of giants in the nearby GC M30. Although our measurements show that NGC 2419 is unusual in some respects, its bulk properties do not provide compelling evidence for a difference between inner and outer halo GCs.

    The possibility is considered to obtain from the extraatmospheric submillimeter spectrophotometry of galaxy clusters the ratios vsub(r)/Tsub(e) for clusters intergalactic gas that permits, together with the X-ray measurements of electronic temperature Tsub(e) in the case of hot scattering gas to determine absolute radial peculiar velocities vsub(r) of galaxy clusters relative to the relic radiation. By simulating such peculiar velocities as an example for the system of bandpass filters in the wavelength range 300 μm - 2 mm the accuracy of vsub(r) estimates is proved to be about 300 km/s (not taking into account the errors in Tsub(e)) the sensitivity of deeply cooled submillimeter bolometers being 1x10 -15 W/Hzsup(1/2)

    The objective of the present study was to summarize the literature data concerning the peculiar features of the psycho-emotional status of the patients presenting with nasal deformities and the importance of its evaluation for the preparation for the surgical rhinoplastic intervention. We present the results of analysis of the materials pertinent to the history and the current state of the psychological aspects of rhinoplasty, the importance of the development and application of the diagnostic tools for the evaluation of the psycho-emotional status of the patients presenting with deformations of the external nose. It is concluded that the disregard of the psycho-emotional status of the patients by a thonosurgeon and the resulting mistakes in determining indications for the surgical intervention can be the causes accounting for the patient's dissatisfaction with the outcome of even an ideally performed operation.

    The Picos II Paleontological Site (PIIPS), located in the city of Piranhas, in Alagoas State, is a fossil deposit with a pond-like geomorphological feature, a kind of peculiar deposit for the Quaternary of Northeast Brazil. A detailed taphonomic study is presented about the PIIPS assemblage, from material collection to the laboratory analysis. The conservation state of the collected fossils in PIIPS is different from that found in other tank deposits, showing a high degree of specimen preservation. Two taxa of pleistocenic mammals have been identified: Eremotherium laurillardi and Notiomastodon platensis, and fragments of an avian bone, whose taxonomic identification was not possible. The taphonomic analysis indicates that the deposited material experienced a short transportation in high-energy event, with a short period of subaerial exposure before the final burial, where at least the final disarticulation occurred in situ, which explains the high conservation level of the material. The sedimentological analysis made in each layer of the deposit corroborates the information related to the transport of the material, which were obtained in taphonomic analysis. Regarding these aspects, PIIPS reflects nearly non-biased biocenotic patterns. The well-preserved material found in PIIPS demonstrates the great potential of deposits with pond-like geomorphological features, with sidelines that are less steep than traditional tanks, providing smoother transport and accommodation for skeletal elements, which is a distinguishing factor in preserving fossils of vertebrates.

    The stability analysis of a rectangular plate loaded in compression is presented, a specialized code based on FEM has been created. Special finite element with 48 degrees of freedom has been used for analysis. The nonlinear finite element method equations are derived from the variational principle of minimum of total potential energy. To trace the complete nonlinear equilibrium paths, the Newton-Raphson iteration algorithm is used, load versus displacement control was changed during the calculation process. The peculiarities of the effects of the initial imperfections on the load-deflection paths are investigated with respect to aspect ratio of the plate. Special attention is paid to the influence of imperfections on the post-critical buckling mode.

  13. Life at the limits: peculiar features of lichen symbiosis related to extreme environmental factors

    Science.gov (United States)

    de Vera, J.-P.; Horneck, G.; Rettberg, P.; Ott, S.

    A lichen is a symbiotic association formed by a mycobiont (fungi), a photobiont (algae) and/or a cyanobacteria. The special symbiotic contact and interaction between the bionts in a lichen is a prerequisite for maintainance of viability for each of them during influences by harsh environmental factors. In nature parameters like UV radiation, low or high temperatures and dryness may have a destructive impact on all life functions of an organism. But with lichens the evolution has created a peculiar symbiosis which enables a wide variety of lichen species to colonize habitats where their separate bionts would not be able to survive. The results of our investigations are demonstrating these aspects (de Vera et al. 2003, 2004).We have already investigated the viability of the entire lichen thallus, the embedded spores in lichen apothecia (fruiting bodies) as well as the isolated spores and isolated photobionts after exposure to most extreme conditions caused by simulated space parameters as extreme UV radiation and vacuum. The results presented here focuse on the survival capacity of the isolated photobionts from the two lichen species Xanthoria elegans and Fulgensia bracteata which are not protected by the fungal structure of the lichen thallus. They are based on examinations using a Confocal Laser Scanning Microscopy (CLSM), analysed by modern methods of the Image Tool Program and by culture experiments. In contrast to photobionts embedded in the entire lichen thallus the isolated photobionts are much more sensitve to the extreme conditions of UV radiation and vaccum: while 50 % of the bionts in an entire lichen thallus are able to cope with simulated extreme space conditions (UV-radiation: λ quad ≥ 160nm and vacuum: p = 10-5 Pa) during an exposure time of 2 weeks, the viability of the isolated photobiont cells was already decreasing after 2 hours of exposure. All photobiont cells were inactivated after longer exposure times of about 8 hours. Further more analysis

    The recent detection of gravitational waves has generated interest in alternatives to the black hole interpretation of sources. A subset of such alternatives involves a prediction of gravitational wave ‘echoes’. We consider two aspects of possible echoes: first, general features of echoes coming from spacetime reflecting conditions. We find that the detailed nature of such echoes does not bear any clear relationship to quasi-normal frequencies. Second, we point out the pitfalls in the analysis of local reflecting ‘walls’ near the horizon of rapidly rotating black holes.

    Full Text Available Erdheim-Chester disease is a rare non-Langerhans form of histiocytosis with multiple organ involvement. Approximately 20% of patients have xanthoma-like lesions, usually on the eyelids. We report a case of Erdheim-Chester disease in a 32-year-old male who showed peculiar xanthomatous skin lesions and also had atopic dermatitis. His skin manifestations included ring-like yellowish tumors on his periorbital regions, rope necklace-like tumors on his neck, and spindle-shaped tumors on his right preauricular region and cubital fossas. He also had exophthalmos and diabetes insipidus. Chronic eczematous lesions were present on the flexor aspect of his extremities, and his serum eosinophil numbers and immunoglobulin E levels were elevated. A histological examination of his right neck tumor showed foamy macrophages and touton-type giant cells, which were positive for CD68 and CD163 and negative for S-100 and CD1a. We suggest that the complication of atopic dermatitis may have contributed to the uncommon clinical features in this case.

    2014-01-01

    Full Text Available The article examines some peculiarities if grammatical properties of nominal word combinations based on the study of German-speaking Swiss press. The accumulated experience of linguists is analyzed and certain factors influencing the choice of syntactic relations in nominal word combinations with quantitative meaning are researched. It has been established that the choice of syntactic relations in such word combinations is determined by functional style, semantics and grammatical features of nouns - first or second components in a word combination. The aforementioned factors influencing the choice of syntactic relations in quantitative nominal word combinations are studied on the material of Germanspeaking Swiss press. The research revealed a number of peculiarities. First of all, German-speaking Swiss press uses such syntactic relation as genitive subordination quite often, not only on "special occasion" and unlike its use in Germany does not produce a magniloquent, pompous impression. Secondly, it has been established that the choice of syntactic relations in word combinations of the above-mentioned type of word combinations greatly depends on the semantic meaning of the noun - the first component of the word combination - and does not always coincide with the grammatical properties in nominal combinations in Germany. Thirdly, a clear dependence of syntactic relations choice is observed. Moreover, the article highlights the importance of grammatical features of the second component. These are such features as gender, number, case accompanied by noun declension. All the afore-mentioned features help to define the type of syntactic relations, which nominal quantitative word combinations may be connected by. The results of the comparisons of grammatical properties of quantitative nominal word combinations in German and Swiss press are demonstrated in a table below.

    2015-09-01

    We tested the usefulness of name-letter preference scores as indirect indicators of self-esteem by exploring whether multiple unsupervised self-administrations of letter rating tasks within a short period of time yield useful data. We also examined whether preferences for initials and noninitial name-letters tap different aspects of self-esteem. Participants from a community sample (N = 164; 58 men and 106 women, 17-67 years, Mage = 34.57, SD = 13.28) completed daily letter rating tasks and state self-esteem questionnaires for 7 consecutive days. They also completed a trait self-esteem questionnaire on the first measurement day as well as 6 months later. Preference scores for first-name initials were stronger but more unstable than preference scores for other name-letters. Preferences for first-name initials were primarily associated with directly measured state self-esteem whereas preferences for noninitials were primarily associated with directly measured trait self-esteem even if the latter was measured 6 months later. Thus, we showed that preferences for initials and noninitials are not simply interchangeable. Previous letter rating studies, which almost exclusively used initial preferences, should be interpreted in terms of state rather than trait self-esteem. In future studies, researchers should focus on the name-letter preference that reflects the aspect of self-esteem they wish to address. (c) 2015 APA, all rights reserved.

  4. Sensorimotor Behaviour Reflects Lexical and Grammatical Aspect in Czech: An Eye Tracking Study

    Directory of Open Access Journals (Sweden)

    Michal Kořenář

    2016-11-01

    Full Text Available Thinking and speaking about events is a process tightly connected with time perception. We can express when an event has occurred with respect to other events, whether it was a durative or a one-time event, whether it was an ongoing or already finished event, etc. Every human language has its own way and extent to which this complex temporal structure of experienced events is expressed. Upon hearing a story we construct a mental representation of the communicated event (e.g. Givón 1992. Some studies show that this construction already evolves during online processing, thanks to instantly accessible language processing cues (Altman and Kamide 1999, Ferretti, McRae and Hatherell 2001, McRae, Ferretti and Amyote 1997. These cues are employed to capture the intricate temporal structure of the story, for instance. They arise from the interplay of the three basic linguistic components (structure, meaning and function and as such are consistent with a constructional view of language (e.g. Fillmore 1988. Even subtle changes of any of the linguistic cues may lead to a different mental representation. Examples of the sources of grammatical markers and lexical categories from which the linguistic cues arise are grammatical and lexical aspect. In the linguistic field, a lot of attention has been paid to analyses of how those sources of temporal cues function within a language system. However, there is a lack of empirical data on how grammatical and lexical aspect interact, and what the effects of such an interaction are. The present study aims to investigate the link between the complex system of temporal cues and sensorimotor representation in Czech speakers, with specific focus on grammatical verb aspect and so-called event telicity, i.e. lexical aspect, all of which will be further described below.

  5. Reflection Positive Stochastic Processes Indexed by Lie Groups

    Reflection positivity originates from one of the Osterwalder-Schrader axioms for constructive quantum field theory. It serves as a bridge between euclidean and relativistic quantum field theory. In mathematics, more specifically, in representation theory, it is related to the Cartan duality of symmetric Lie groups (Lie groups with an involution) and results in a transformation of a unitary representation of a symmetric Lie group to a unitary representation of its Cartan dual. In this article we continue our investigation of representation theoretic aspects of reflection positivity by discussing reflection positive Markov processes indexed by Lie groups, measures on path spaces, and invariant gaussian measures in spaces of distribution vectors. This provides new constructions of reflection positive unitary representations.

    Ethics can be defined as a reflection on nature and a definition of “the good”. Individuals value qualities and things dissimilarly, most visibly, but they also value their goods in different ways, in different relations to each other, for different reasons, and to different ends. These differences are very applicable to sustainability. In other words, sustainability cannot be achieved without attention to its ethical dimensions. The aim of this research is to examine the ethical aspects of s...

    This research thesis reports the study of organic thin films by using X-ray-based technologies, and more particularly X-ray reflectivity. After some recalls on X ray diffraction, and on the fabrication of Langmuir-Blodgett films, the author shows how, by combining three X-ray-based techniques, it is possible to study a volume structure of a thin film. He describes the technique of measurement by X- ray reflexivity, its experimental implementation, and methods for result interpretation. In the next part, the author reports the study of peculiar interference effects which are noticed in reflexivity on Langmuir-Blodgett films, and then describes the nature of these films by correlating results of X ray reflexivity with direct observations performed by electronic microscopy on replica [fr

  18. How assessment and reflection relate to more effective learning in adaptive management

    Directory of Open Access Journals (Sweden)

    Harry Biggs

    2011-05-01

    Two other studies in the Kruger National Park, which have examined learning specifically, are also discussed. One of them suggests that in a complex environment, learning necessarily has a dual nature, with each component of seven contrasting pairs of the aspects of learning in partial tension with the other. We use these dualities to further probe assessment, reflection, inter-relatedness and learning in the cases presented. Each contrasting aspect of a ‘learning duality’ turns out to emphasise either assessment or reflection, which reinforces the idea that both are needed to facilitate sufficient learning for successful adaptive management. We hope this analysis can act as a springboard for further study, practice and reflection on these important and often underrated components of adaptive management. Conservation implications: The better understanding of assessment and reflection as being largely separate but complementary actions will assist adaptive management practitioners to give explicit attention to both, and to relate them better to each other.

  19. Kinematics of reflections in subsurface offset and angle-domain image gathers

    Science.gov (United States)

    Dafni, Raanan; Symes, William W.

    2018-05-01

    Seismic migration in the angle-domain generates multiple images of the earth's interior in which reflection takes place at different scattering-angles. Mechanically, the angle-dependent reflection is restricted to happen instantaneously and at a fixed point in space: Incident wave hits a discontinuity in the subsurface media and instantly generates a scattered wave at the same common point of interaction. Alternatively, the angle-domain image may be associated with space-shift (regarded as subsurface offset) extended migration that artificially splits the reflection geometry. Meaning that, incident and scattered waves interact at some offset distance. The geometric differences between the two approaches amount to a contradictory angle-domain behaviour, and unlike kinematic description. We present a phase space depiction of migration methods extended by the peculiar subsurface offset split and stress its profound dissimilarity. In spite of being in radical contradiction with the general physics, the subsurface offset reveals a link to some valuable angle-domain quantities, via post-migration transformations. The angle quantities are indicated by the direction normal to the subsurface offset extended image. They specifically define the local dip and scattering angles if the velocity at the split reflection coordinates is the same for incident and scattered wave pairs. Otherwise, the reflector normal is not a bisector of the opening angle, but of the corresponding slowness vectors. This evidence, together with the distinguished geometry configuration, fundamentally differentiates the angle-domain decomposition based on the subsurface offset split from the conventional decomposition at a common reflection point. An asymptotic simulation of angle-domain moveout curves in layered media exposes the notion of split versus common reflection point geometry. Traveltime inversion methods that involve the subsurface offset extended migration must accommodate the split geometry

    We present results of the study of peculiar motions of 57 clusters and groups of galaxies in the regions of the Corona Borealis (CrB), Bootes (Boo), Z5029/A1424, A1190, A1750/A1809 superclusters of galaxies and the galaxy clusters located beyond massive structures (0.05 Boo. In the most massive A2065 cluster in the CrB supercluster, no peculiar velocity was found. Peculiar motions of the other galaxy clusters can be caused by their gravitational interaction both with A2065 and with the A2142 supercluster. It has been found that there are two superclusters projected onto each other in the region of the Bootes supercluster with a radial velocity difference of about 4000 kms-1. In the Z 5029/A1424 supercluster near the rich Z5029 cluster, the most considerable peculiar motions with a rms deviations of 1366 ± 170 kms-1 are observed. The rms deviations of peculiar velocities of 20 clusters that do not belong to large-scale structures is equal to 0 ± 20 kms-1. The whole sample of the clusters under study has the mean peculiar velocity equal to 83 ± 130 kms-1 relative to the cosmic microwave background.

    We present an Echelle+CCD, high signal-to-noise ratio, high-resolution (R = 20,000) spectroscopic atlas of 108 well-known objects representative of the most common types of peculiar and variable stars. The wavelength interval extends from 4600 to 9400 A and includes the RAVE, Gaia, and HERMES wavelength ranges. Multi-epoch spectra are provided for the majority of the observed stars. A total of 425 spectra of peculiar stars, which were collected during 56 observing nights between 1998 November and 2002 August, are presented. The spectra are given in FITS format and heliocentric wavelengths, with accurate subtraction of both the sky background and the scattered light. Auxiliary material useful for custom applications (telluric dividers, spectrophotometric stars, flat-field tracings) is also provided. The atlas aims to provide a homogeneous database of the spectral appearance of stellar peculiarities, a tool useful both for classification purposes and inter-comparison studies. It could also serve in the planning and development of automated classification algorithms designed for RAVE, Gaia, HERMES, and other large-scale spectral surveys. The spectrum of XX Oph is discussed in some detail as an example of the content of the present atlas.

    Peculiarities of the HF-radiowave propagation between ground stations and low-flying satellites near and below the maximum of the F area are studied through the method of mathematical modeling. It is established that the signal may propagate by three trajectories. The first one is below the satellite orbit. The turn altitudes of the second and the third beams are above the satellite orbit. Availability of three trajectories leads to the three-digit dependence of the group ways on the working frequency F. The P(f) curves for different satellite distances from a reception point and its orbit altitudes for the isotropic and magnetoactive ionosphere are presented

    2011-10-01

    NGC 2419 is a massive outer halo Galactic globular cluster (GC) whose stars have previously been shown to have somewhat peculiar abundance patterns. We have observed seven luminous giants that are members of NGC 2419 with Keck/HIRES at reasonable signal-to-noise ratio. One of these giants is very peculiar, with an extremely low [Mg/Fe] and high [K/Fe] but normal abundances of most other elements. The abundance pattern does not match the nucleosynthetic yields of any supernova model. The other six stars show abundance ratios typical of inner halo Galactic GCs, represented here by a sample of giants in the nearby GC M30. Although our measurements show that NGC 2419 is unusual in some respects, its bulk properties do not provide compelling evidence for a difference between inner and outer halo GCs. Based in part on observations obtained at the W. M. Keck Observatory, which is operated jointly by the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration.

  7. On the Peculiar Molecular Shape and Size Dependence of the Dynamics of Fluids confined in a Small-Pore Metal-Organic Framework

    KAUST Repository

    2018-05-15

    Force field based-Molecular dynamics simulations were deployed to systematically explore the dynamics of confined molecules of different shapes and sizes, i.e. linear (CO2 and N2) and spherical (CH4) fluids, in a model small pore system, i.e. the Metal-Organic Framework SIFSIX-2-Cu-i. These computations unveil an unprecedented molecular symmetry dependence of the translational and rotational dynamics of fluids confined in channel-like nanoporous materials. In particular this peculiar behaviour is reflected by the extremely slow decay of the Legendre reorientational correlation functions of even-parity order for the linear fluids which is associated to jump-like orientation flips, while the spherical fluid shows a very fast decay taking place in a sub-picosecond time scale. Such a fundamental understanding is relevant to diverse disciplines such as in chemistry, physics, biology and materials science where diatomic or polyatomic molecules of different shapes/sizes diffuse through nanopores.

Study objective: study lifestyle peculiarities of myopic schoolchildren. Methods: 349 pupils from 5–9 forms of a school with profound studying of various subjects were interviewed using a specially designed questionnaire. After a preventive examination the schoolchildren were divided into two groups according to ophthalmologists report, comparable by age and gender (162 myopic vs 182 without myopia. Results: all participants were poorly informed about myopia and possible preventive care, and during breaks behaved themselves in an unreasonable way judging from the positions of vision care. At home myopic children tended to spend more time doing their homework and on extracurricular studies, as well as on reading; these children in general spent more time watching TV or working on a computer; failed to rest properly, couldn’t switch from one type of activity to another, were working under conditions of unreasonable vision workload. In contrast to participants from control group, myopic schoolchildren spent less time resting: they were sleeping less and spent less time outdoors. Conclusion: revealed lifestyle peculiarities of modern myopic schoolchildren must become a target for preventive care. Their irrational lifestyle can be corrected by correction of daily routine, better organization of extracurricular exercises, visual exercises, better education of schoolchildren about disease risk factors.Key words: schoolchildren, myopia, risk factors.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2011; 10 (4: 5–9

  15. The curious case of SN 2011dn: A very peculiar type Ia supernova?

    Science.gov (United States)

    Rachubo, Alisa

    Type Ia supernovae (SNe Ia) are excellent cosmological distance indicators due to the uniformity in their light curves, which led to the major discovery of the accelerated expansion of the universe. However, SNe Ia are not so uniform as one may expect, as there are many peculiar SNe Ia that exhibit differences in their photometric and spectroscopic behavior from normal SNe Ia. One of the goals of supernova cosmology today is to produce a cleaner sample of SNe Ia without these peculiar SNe Ia. Here we consider SN 2011dn, a peculiar SN Ia candidate. In 2011, Salvo, et al. carried out a preliminary analysis of a subset of the data prescribed here, and identified spectral and photometric peculiarities in this object's evolution that warranted further analysis. Here, we present a complete re-reduction and reanalysis of B, V,R, and I photometry of SN 2011dn obtained at Mount Laguna Observatory, spanning from 7 days before maximum light in B to 88 days past maximum light. In addition, we also consider total flux spectra from 9 days before maximum light to 4 days after maximum light, along with ultraviolet (UV) photometry obtained with the Swift telescope. From SN 2011dn's optical spectra, we find that SN 2011dn most closely resembles a SN 1991T-like type Ia supernova ('91T-like SN Ia). Such SNe Ia are typically more luminous than normal SNe Ia, and possess broader (i.e., they decline less rapidly than normal from maximum light) light curves. Their Deltam15(B) (drop in B magnitude 15 days after maximum light) are typically significantly less than the canonical value of 1.1, and can be as low as 0.8. In the earlier preliminary analysis, Salvo et al. measured a surprisingly high Deltam15(B) value for SN 2011dn, of ˜ 1.1. Since SN 2011dn was embedded in UGC 11501 (its host galaxy), however, it is possible that some of the light from the host galaxy was included in the photometric aperture, resulting in inaccurate photometric measurements. Here, in order to better isolate the

It is found out that during the saturation the solid solution oversaturated with nitrogen is formed; some increase in hardness in the process is a result of solid solution hardening and the increase of thickness of nitride zone; however the main growth of the layer hardness is achieved during the cooling as a result of α phase precipitating hardening

  18. Peculiarities of spin polarization inversion at a thiophene/cobalt interface

    2013-03-20

    We perform ab initio calculations to investigate the spin polarization at the interface between a thiophene molecule and cobalt substrate. We find that the reduced symmetry in the presence of a sulfur atom (in the thiophene molecule) leads to a strong spatial dependence of the spin polarization of the molecule. The two carbon atoms far from the sulfur acquire a polarization opposite to that of the substrate, while the carbon atoms bonded directly to sulfur possess the same polarization as the substrate. We determine the origin of this peculiar spin interface property as well as its impact on the spin transport.

    A peculiar Herbig-Haro object, named HH 131, has been discovered by low-dispersion slit spectroscopy and narrowband CCD imaging. It lies well outside the dark cloud Lynds (L) 1641 toward the southwest. Accordingly, it has no associated molecular cloud, but it may be related to a cloud of atomic hydrogen. Its morphology is also unique, showing a fairly high degree of axisymmetric structure as well as a sort of double helix. No likely candidates for its energy source have been found in the IRAS Point Source Catalog, or by slit spectroscopy and an objective-prism Schmidt survey of nearby stars. 24 refs

  1. Strömgren uvby photometry of the peculiar globular cluster NGC 2419

    NGC 2419 is a peculiar Galactic globular cluster offset from the others in the size-luminosity diagram, and showing several chemical abundance anomalies. Here, we present Strömgren uvby photometry of the cluster. Using the gravity- and metallicity-sensitive c1 and m1 indices, we identify a sample of likely cluster members extending well beyond the formal tidal radius. The estimated contamination by cluster non-members is only one per cent, making our catalogue ideally suited for spectroscopic follow-up. We derive photometric [Fe/H] of red giants, and depending on which metallicity calibration from the literature we use, we find reasonable to excellent agreement with spectroscopic [Fe/H], both for the cluster mean metallicity and for individual stars. We demonstrate explicitly that the photometric uncertainties are not Gaussian and this must be accounted for in any analysis of the metallicity distribution function. Using a realistic, non-Gaussian model for the photometric uncertainties, we find a formal internal [Fe/H] spread of σ=0.11+0.02-0.01 dex. This is an upper limit to the cluster's true [Fe/H] spread and may partially, and possibly entirely, reflect the limited precision of the photometric metallicity estimation and systematic effects. The lack of correlation between spectroscopic and photometric [Fe/H] of individual stars is further evidence against a [Fe/H] spread on the 0.1 dex level. Finally, the CN-sensitive δ4, among other colour indices, anti-correlates strongly with magnesium abundance, indicating that the second-generation stars are nitrogen enriched. The absence of similar correlations in some other CN-sensitive indices supports the second generation being enriched in He, which in these indices approximately compensates the shift due to CN. Compared to a single continuous distribution with finite dispersion, the observed δ4 distribution of red giants is slightly better fit by two distinct populations with no internal spread, with the nitrogen

    Thoughtful decision-making to resolve socioscientific issues is central to science, technology, society, and environment (STSE) education. One approach for attaining this goal involves fostering students' decision-making processes. Thus, the present study explores whether the application of decision-making strategies, combined with reflections on the decision-making processes of others, enhances decision-making competence. In addition, this study examines whether this process is supported by elements of self-regulated learning, i.e., self-reflection regarding one's own performance and the setting of goals for subsequent tasks. A computer-based training program which involves the resolution of socioscientific issues related to sustainable development was developed in two versions: with and without elements of self-regulated learning. Its effects on decision-making competence were analyzed using a pre test-post test follow-up control-group design ( N = 242 high school students). Decision-making competence was assessed using an open-ended questionnaire that focused on three facets: consideration of advantages and disadvantages, metadecision aspects, and reflection on the decision-making processes of others. The findings suggest that students in both training groups incorporated aspects of metadecision into their statements more often than students in the control group. Furthermore, both training groups were more successful in reflecting on the decision-making processes of others. The students who received additional training in self-regulated learning showed greater benefits in terms of metadecision aspects and reflection, and these effects remained significant two months later. Overall, our findings demonstrate that the application of decision-making strategies, combined with reflections on the decision-making process and elements of self-regulated learning, is a fruitful approach in STSE education.

    In this article I reflect on the peculiarities of contemporary ethnographic research, highlighting some challenges inherent to this process. The discussion focuses in particular on the following aspects: the limits imposed by the clear reduction in immersion time in the field; the challenges in learning about ethnographic work, either in the process of observation or interaction in the field, or in the task of textual production; issues of an epistemological and ethical nature that deserve particular attention on the part of practitioners of the ethnographic approach and the scientific community in general. It is especially appropriate to foster debate around the ethnographic method, addressing its peculiarities, operational complexity and potential as a tool for knowledge production, in the sphere of health/public health, bearing in mind the marked increase of this approach in this field.

    Full Text Available While heavy stress loads seem an unavoidable aspect of entrepreneurship, the positive side of stress (often referred to as ‘eustress’ remains a neglected area of research. This paper contributes to entrepreneurship research by linking the research streams of eustress and reflective practice. As a tool for analysing and developing thoughts and actions, reflective practice plays an important role in the interpretative work essential to positive stress experiences. Following an overview of approaches to stress at work, eustress and reflective practice, the paper explores how entrepreneurs experience the role of positive stress and reflective practice in their work and describes the reflective tools utilized by entrepreneurs in promoting eustress. The research process was designed to support reflective dialogue among the 21 Finnish entrepreneurs from different fields who participated in the study, with results based mainly on qualitative interviews. Nine of the interviewed entrepreneurs also kept a positive stress diary, including a three-day physiological measurement analysing their heartbeat variability. The findings suggest that positive stress and reflective practice are intertwined in the experiences of entrepreneurs and illustrate the role of reflective practice as a crucial toolset for promoting positive stress, comprising six reflective tools: studying oneself, changing one’s point of view, putting things into perspective, harnessing a feeling of trust, regulating resources and engaging in dialogue. Individual reflective capabilities vary, and a theory-driven division of reflective practice into individual, social and contextual dimensions is considered useful in understanding those differences. The research offers a starting point for exploring how eustress and reflective practice affect the well-being of entrepreneurs

    Full Text Available Nowadays there is a significant increase of the incidence of left-handedness and sinistrality among schoolchildren. Theydemonstrate a large number of left-sided motor and sensory preferences which are considered as external markers offunctional hemispheric asymmetry of the brain. The purposes of this study are to investigate gender peculiarities and specificityof age-related dynamics of laterality pattern’s formation in junior schoolchildren and to find out educational peculiarities anddifficulties of left-handed children. The findings show that left-handers differ greatly in their mental development by havingsome peculiarities of intelligence, world’s perception and prevailing thinking strategies, ways of memorization, specificity ofemotional-affective expression. The main problems of left-handed children in school performance are academic failure, lack ofperseverance, anxiety neurosis, and extreme emotional lability. Integrated development of the left hemisphere and the righthemisphere thinking of left-handed schoolchildren is a favorable condition for harmonious personal and intellectualdevelopment and effective mastering of various modules of the school curriculum. The technological solution of the problem ofteaching the children with left-sided laterality is to include in educational programs some special exercises to developimagination, emotional sensitivity, integrity of perception, global view to the problems, creativeness, and original approachesto tasks’ solving. So a complex program for the intensive development of the right hemisphere of children who demonstrateleft-sided laterality to overcome the possible failure at primary school is proposed in this paper.

    Full Text Available There has been some acknowledgement in the published literature that reflection is a crucial element of the evidence based library and information practice (EBLIP model we have adopted (Booth 2004, 2006; Grant 2007; Helliwell 2007. As we work through a problem and try to incorporate the best available evidence into our decision making, reflection is required at several stages, including the very identification of the problem through to our assessment of the process itself and what we have learned in order to inform future practice. However, reflection and reflective writing have not fully been integrated into the process we espouse, and very little has been done to look more closely at this element of the model and how it can be integrated into professional learning.In a recently published research article, Sen (2010 confirms the relationship between reflection and several aspects of professional practice. These include critical review and decision making, two aspects that are tied closely to the evidence based process. Sen notes: Students were more likely to show evidence of learning, self‐development, the ability to review issues crucially, awareness of their own mental functions, ability to make decision [sic] and being empowered when they had mastered the art of reflective practice and the more deeply analytical reflective writing. (p.84 EBLIP (the journal tries to incorporate elements of reflection within the articles we publish. While we clearly believe in the need for our profession to do quality research and publish that research so that it can be accessible to practitioners, we also know that research cannot be looked at in isolation. Our evidence summaries are one way of reflecting critically on previously published research, and in the same vein, our classics bring older research studies back to the foreground. This work needs to continue to be discussed and looked at for its impact on our profession.More directly, the Using

    We report that the sintering at 1000 °C of silica nanoparticles (an average diameter of 14 nm) produces a transparent sample that exhibits a bright visible emission under UV excitation. The use of time resolved luminescence spectroscopy and a tunable laser source allows us to single out three contributions centered at 1.96 eV, 2.41 eV and 3.43 eV. The excitation spectra of these emissions evidence bell shaped bands consistent with transitions between localized defects’ states. For each emission we study the intensity and the lifetime in the temperature range from 300 K down to 10 K, thus evidencing the competition between radiative and non-radiative processes in the optical cycle of luminescent centers. The comparison with the luminescence properties of silica, both nanoparticles and bulk, points out that the observed emissions are peculiar to the sintered silica network. - Highlights: • Solid-phase sintering at 1000 °C of silica nanoparticles produces a transparent sample. • Sintered silica nanoparticles emit a bright luminescence under UV excitation. • Three emissions, centered around 2.0 V, 2.4 eV and 3.4 eV, are distinguished on the basis of the excitation and decay properties. • The observed excitation/emission bands originate from localized defect states peculiar to the sintered silica network. • The luminescence efficiency decreases with temperature due to the activation of non-radiative channels.

    2003-05-01

    Two approaches dominate current thinking in health and welfare: evidence-based practice and reflective practice. Whilst there is debate about the merits of evidence-based practice, reflective practice is generally accepted with critical debate as an important educational tool. Where critique does exist it tends to adopt a Foucauldian approach, focusing on the surveillance and self-regulatory aspects of reflective practice. This article acknowledges the critical purchase on the concept of reflective practice offered by Foucauldian approaches but argues that microsociological and discourse analytic approaches can further illuminate the subject and thus serve as a complement to them. The claims of proponents of reflective practice are explored, in opposition to the technical-rational approach of evidence-based practice. Reflective practice tends to adopt a naive or romantic realist position and fails to acknowledge the ways in which reflective accounts construct the world of practice. Microsociological approaches can help us to understand reflective accounts as examples of case-talk, constructed in a narrative form in the same way as case records and presentations.

    Full Text Available The rates of modern technologies development is such that educational programs are constantly required to be enlarged with new material. However, the introduced supplements often do not take into account the limited possibilities of perceiving amounts of information offered in class. As a result, a significant number of graduates get diplomas of educational institutions with a number of pathologies. Despite heavy load during training, the knowledge of a graduate is often not enough to recognize him ready to participate in modern production. The problem of providing quality education by creating a technology making it possible to maximize students’ knowledge while reducing the number of messages transmitted in the classroom. Consideration of the educational process in the form of an information system with messages transmitted in the form of images is proposed as one of the ways of solving it. The work assumed that each message is reflected in the consciousness of the source and receiver of information in the form of mental images. Mental images of the teacher and student are considered as a convolution of information. The analysis of peculiarities of mental images formation and development is given, a model of the mechanism of pattern information transmission is proposed. The model of transmitting sign, pattern, and symbol information is described. The communication bandwidth between the participants  of the educational process is considered as depending on their goal setting, training, physiological and emotional features, as well as a number of other non-formalized factors. Graduates of educational institutions are considered as means of producing intellectual products, and the purpose of obtaining knowledge is proposed to be formed based on the definition of the attractor of developing the “teacher-student” system. A principle of organizing educational processes is proposed: the education technology should not violate the consistency

    Full Text Available Using reflective letter-writing as a method of generating data, a group of four researchers embarked on a collaborative autoethnographic inquiry into the emotional dimensions of researching social aspects of HIV & AIDS. In this article, we use the medium of a narrative dialogue to represent and re-examine our reflective letter-writing method. The dialogue draws attention to key features of reflective letter-writing as a collaborative autoethnographic research method and, in so doing, highlights and explores the nature, potential significance, and challenges of this method. Our discussion points to the value of a collaborative process of reflective letter-writing as a way for researchers to access and portray emotional aspects of their research experience, to deepen their engagement with these emotional dimensions, and to gain insight into their own and others' lived research experiences.

    Understanding of material behaviour at nanoscale under intense laser excitation is becoming critical for future application of nanotechnologies. Nanograting formation by linearly polarised ultra-short laser pulses has been studied systematically in fused silica for various pulse energies at 3D laser printing/writing conditions, typically used for the industrial fabrication of optical elements. The period of the nanogratings revealed a dependence on the orientation of the scanning direction. A tilt of the nanograting wave vector at a fixed laser polarisation was also observed. The mechanism responsible for this peculiar dependency of several features of the nanogratings on the writing direction is qualitatively explained by considering the heat transport flux in the presence of a linearly polarised electric field, rather than by temporal and spatial chirp of the laser beam. The confirmed vectorial nature of the light-matter interaction opens new control of material processing with nanoscale precision.

In this commentary, I attempt to extend the conversation regarding these issues to the need for teachers to be aware about their own environmental beliefs, which could be guiding their teaching. I close with a consideration for the need for environmental teachers to be reflective practitioners, using reflection upon the ends of education, their environmental values and ideas and the moral and ethical aspects of teaching, for challenging students' beliefs and empowering them to make informed environmental decisions, contributing thereby to the building of more just and environmental sustained societies.

    Facilitation of reflective practice is critical for the ongoing demands of health care practitioners. Reflective thinking concepts, grounded in the work of Dewey and Schön, emphasize critical reflection to promote transformation in beliefs and learning necessary for reflective practice. The Reflective Thinking Questionnaire (QRT) and Revised Study Process Questionnaire (RSPQ-2F) assess skill aspects of professional reasoning, with promise for measuring changes over time. The purpose of this study was to examine the reliability and responsiveness and the model validity of reflective thinking and approaches to learning measures for U.S. health professions students enrolled in entry-level occupational (MOT) and physical therapy (DPT) programs. This measurement study addressed reliability and responsiveness of two measures, the QRT and RSPQ-2F, for graduate health professionals. A convenience sample of 125 MOT and DPT students participated in the two-measure, test-retest investigation, with electronic data collection. Outcomes support the stability of the four-scale QRT (ICC 0.63 to 0.82) and the two-scale RSPQ-2F (ICC 0.91 and 0.87). Descriptive data supporting responsiveness are presented. With noted limitations, the results support the use of the QRT and RSPQ-2F measures to assess changes in reflective thinking and approaches to learning. Measurement of these learning outcomes furthers our understanding and knowledge about instructional strategies, development of professional reasoning, and fostering of self-directed learning within MOT and DPT programs.

    This work is devoted to the neutron-activation analysis of medicines of vegetation origin and some herbs, vegetables, fruits and cereals, which are used in oriental medicine, in order to reveal peculiarities of distribution of studied elements in them and possible relations between this distribution and parameters of oriental medicine. The sampling involving 85 species and their preparation for analysis, as well as complex of necessary methodological studies were performed and the method of sample analysis for 14 macro- and microelements (Na, Al, Cl, K, Sc, Mn, Fe, Co, Cu, Zn, Br, J, La, Au) was developed. The studies carried out have enabled one to obtain data on concentrations of these elements and to reveal peculiarities of their distribution in the samples under interest. It was revealed herbs, fruits and cereals with pronounced higher concentrations (with respect to the mean values) of one or another element, which are perhaps concentrators of those elements, as well as samples with lower concentrations of elements (see table). It is indicative that in all herbs only enhanced concentrations of elements are observed, but in fruits and cereals-only lowered concentrations of elements. These results can be of interest for geochemical ecology, dietology, therapy, as well as for activities on correction of elemental content of ecosystems, including soils, and alive organisms It is suggested to continue studies with extension of range of object types and analysed elements. Mathematical analysis of the obtained results was performed with comparison of concentrations of a number of elements in the different objects with classifying parameters ('cold-hot' and 'dry-wet') of these objects according to oriental medicine. In the current stage of studies no relation between these parameters and concentrations has been found. It does not mean that there are not such relations at all, they may be revealed with extension and development of our' studies.

    Reflective thinking is an important component in the world of education, especially in professional education of teachers. In learning mathematics, reflective thinking is one way to solve mathematical problem because it can improve student's curiosity when student faces a mathematical problem. Reflective thinking is also a future competence that should be taught to students to face the challenges and to respond of demands of the 21st century. There are many factors which give impact toward the student's reflective thinking when student solves mathematical problem. One of them is cognitive style. For this reason, reflective thinking and cognitive style are important things in solving contextual mathematical problem. This research paper describes aspect of reflective thinking in solving contextual mathematical problem involved solution by using some mathematical concept, namely linear program, algebra arithmetic operation, and linear equations of two variables. The participant, in this research paper, is a male-prospective teacher who has Field Dependent. The purpose of this paper is to describe aspect of prospective teachers' reflective thinking in solving contextual mathematical problem. This research paper is a descriptive by using qualitative approach. To analyze the data, the researchers focus in four main categories which describe prospective teacher's activities using reflective thinking, namely; (a) formulation and synthesis of experience, (b) orderliness of experience, (c) evaluating the experience and (d) testing the selected solution based on the experience.

    We propose a method to determine the DNA-cisplatin binding mechanism peculiarities by monitoring the mechanical properties of these complexes. To accomplish this task, we have performed single molecule stretching experiments by using optical tweezers, from which the persistence and contour lengths of the complexes can be promptly measured. The persistence length of the complexes as a function of the drug total concentration in the sample was used to deduce the binding data, from which we show that cisplatin binds cooperatively to the DNA molecule, a point which so far has not been stressed in binding equilibrium studies of this ligand.

    On the basis of investigating the peripheral blood lymphocytes the immunologic state in 81 patients with uterine cervix carcinoma is estimated. It is established that there is a considerable decrease of indices in the T-immune system in patients with uterine cervix carcinoma. The detection of reductions in the immunogram indices in the initial stage plays a definte diagnostic role in the detection of metastases, permits to forecast the process generalization, and consequently, to determine the treatment tactics. It is established that under the effect of combined radiation treatment the T-system is mostly injured. Consequently, pronounced postradiation depression is prognostically unfavourable. The examination of another group of patients has shown that the probability of development of lymphogenic metastases in uterine cervix carcinoma is mainly determined by immuno-morphological peculiarities of regional lymph nodes [ru

    Graphical abstract: The change of sign of the MCD signal with temperature and magnetic field increase can take place. The origin of this peculiarity is explained by the strong orbital contribution. Highlights: → MCD C-term saturation behavior of the exchange coupled cobalt dimer. → Strong orbital contribution to the magneto-optical behavior. → Change of sign of the MCD signal with temperature and magnetic field increase. - Abstract: The MCD C-term saturation behavior of the exchange coupled octahedrally coordinated cobalt dimers is studied for different types of distortion of the local surrounding of each interacting ion. It was found that in the case of antiferromagnetic exchange interaction the change of sign of the MCD signal with temperature and magnetic field increase can take place. This signal behavior is not the result of overlapping of different electronic transitions and it is characteristic of an individual MCD line. The origin of this magneto-optical behavior is explained by the strong contribution coming from the unquenched orbital angular momenta of interacting cobalt ions. The found peculiarity is inherent to complexes composed of nonequivalent cobalt ions as well as to the dimeric complexes with the equivalent Co ions with nonparallel local axes.

    The purpose of this report is to document the environmental aspects and associated environmental impacts of the Bechtel SAIC Company (BSC) scope of work, evaluate the significance of those environmental aspects based on established criteria, and establish environmental objectives and targets for specific environmental aspects. This report is intended to be used by environmental staff in the evaluation of BSC work packages during the annual risk-based planning process. This report shall be fully reviewed and revised annually during the annual work planning process to reflect changes in BSC operations, facilities, and scope of work. Planned BSC work will be evaluated to determine if the work is covered by a previously defined activity, product or service (see Table 2); if work activities require redefinition or addition of a new activity; and if the significant evaluation for each environment aspect is still valid based on scope of planned work. New workscope initiated during the fiscal year through the Baseline Change Proposal process (i.e., not as part of the annual work plan) also will be reviewed for new environmental aspects and determination of whether the new workscope would change the significance rating of any environmental aspect. If a new environmental aspect is identified in a new work activity, product, or service but the aspect is not determined to be significant (see Section 4), then this report can be changed through an interim change notice (ICN). This report can be changed five times through an ICN before a full revision is required. However, if new workscope causes an environmental aspect to be graded as significant using the evaluation process in Section 4, this report shall be revised though a full review and revision

    Full Text Available Recent research efforts have established that self-regulated learning (SRL is necessary for teachers to attain successful professional development. Our study addresses two central questions: under what conditions in preservice teachers' education can SRL processes be enhanced to the optimum level, and how can we assess these processes? The participants of the study were ninety-seven preservice teachers, who were engaged in real-time teaching in a video-digital Microteaching environment. Each participant was randomly assigned to one of two groups: reflective support (RS for SRL or no support (NS for SRL. Participants in the RS group were explicitly exposed to SRL aspects and were directed to address these aspects in their reflective discussions of the teaching experience. The SRL process was measured as an online event during real-time teaching exercises, based on a coding scheme developed for this study to identify and assess the SRL skills by two major aspects: metacognition (planning, information management, monitoring, debugging, and evaluating and motivation (interest and value, self-efficacy, and teaching anxiety. Results indicate that the RS group outperformed the NS group in all SRL measures. Implications for reflective support for SRL and event measures of real-time observations of preservice teachers' SRL are discussed.

    A 57-year-old right-handed woman with a history of left frontal lobe stroke had experienced episodes of language-expression difficulty followed by paraphasia lasting for approximately 30 seconds two years earlier. She was diagnosed with left frontal lobe epilepsy, and a lamotrigine regimen was initiated. This treatment had to be stopped five weeks after initiation because she developed a rash, and her drug lymphocyte stimulation test result was positive. Interestingly, she has since remained seizure free without requiring any antiepileptic medications. This adult case with a peculiar clinical course provides support for the hypothesis of immunomodulation process involvement in epilepsy, a phenomenon that was previously mainly seen in pediatric patients.

    Full Text Available The data of literary sources concerning the bloom of angiosperm plants and deviation in the development of a flower and inflorescence, in particular untimely flowering, was generalized; our observation results of some peculiarities of re-bloom of woody plants in the National Dendrological Park “Sofiyivka” of NAS of Ukraine (NDP “Sofiyivka” were discussed. The flowering process was formed during a long-term evolution of a propagation system of angiosperm plants as a basis of fertilization and further fruit and seed development. As a result of vernalization and photoperiodism reactions, flowering (under regular conditions occurs in the most favorable period for pollination and fertilization of every plant. However, various deviations, in particular, the untimely (most frequently double, sometimes three- and four-fold flowering occurs in this perfect process of generative organ formation of angiosperm plants. An increased number of reports about re-bloom (at the end of summer – at the beginning of fall of the representatives of various woody plant species whose flowers usually blossom in May-June prompts the analysis of the available information concerning the mechanisms of flowering and the causes which lead to deviation of flowering processes. Flowering of the woody plant representatives of the collection fund of the NDP “Sofiyivka” was studied; statistics about re-bloom in different cities of Ukraine were monitored. The classification of re-bloom facts was carried out according to V.L. Vitkovskiy (1984. Although this classification has mostly a stated nature, it was good enough when being formulated and, with certain conditions, it can be applied nowadays. Accordingly, using this classification, abnormal cases can include facts of early summer-fall flowering and early winter flowering. A late spring flowering can be adaptive response of damaged plants to exogenous stresses, due to which the probability of sexual propagation remains

    The reflection due to absorptive potential (-iV i ) for resonant and non-resonant tunneling has been considered. We show that the effect of reflection leads to a non-monotonic dependence of absorption on the strength V i with a maximum absorption of typically 0.5. This has implications for the operation of resonant tunneling devices. General conceptual aspects of absorptive potentials are discussed. (author). 9 refs, 2 figs

    2003-01-01

    The main requirements and peculiarities expected from the BNCT-oriented treatment planning system (TPS) are summarized in this paper. The TPS is a software, which can be integrated or composed by several auxiliary programs. It plays important roles inside the whole treatment planning of the patient's organ in BNCT. However, the main goal is the simulation of the irradiation, in order to obtain the optimal configuration, in terms of neutron spectrum, patient positioning and dose distribution in the tumour and healthy tissues. The presence of neutrons increases the level of complexity, because much more nuclear reactions need to be monitored and properly calculated during the simulation of the patient's treatment. To this purposes several 3D geometry reconstruction techniques, generally based on the CT scanning data, are implemented and Monte Carlo codes are normally used. The TPSs are expected to show also the results (basically doses and fluences) in a proper format, such as isocurves (or isosurfaces) along t...

    Full Text Available For any kind of business such category as risks is peculiar. The research of this category was conducted by scientists from the different sides, certain approaches of protection against risks were developed and instruments of decrease in financial risks are offered. The bank guarantee is one of the most demanded instruments of additional financial protection today. Its active using of the commercial organizations courses questions of the organization of the detailed accounting of guarantees at the principal and the beneficiary. A little concerning the historical aspect of the bank guarantee, authors provided the overview of the determinations of "bank guarantee" characterizing it as the banking service providing distribution of responsibility between the guarantor and the principal under certain conditions. Having considered the essence of the legal nature and features of the bank guarantee recommendations about the organization of the disaggregated financial accounting on off-balance accounts were developed. In particular, need of allocation of a currency type as the directions of conducting the analytics providing correctness of reflection of cost criterion is proved. For the purpose of control of timeliness of carrying out calculations it is recommended to allocate guarantees: coincident and in coincident with primary obligation; short-term and long-term. From the point of view of nature of guarantees payment guarantees and guarantees of obligation fulfilment were allocated. These recommendations concern the beneficiary, and lack of accounting entries at a principal generates need of creation of additional registers and analytical reports which forms were offered by authors. The provided recommendations will allow obtaining transparent information on bank guarantees for the purpose of its full disclosure in the financial reporting.

    Supervision is a basic part of training and ongoing education in cognitive behavioural therapy. Self-reflection is an important part of supervision. The conscious understanding of one's own emotions, feelings, thoughts, and attitudes at the time of their occurrence, and the ability to continuously follow and recognize them are among the most important abilities of both therapists and supervisors. The objective of this article is to review aspects related to supervision in cognitive behavioural therapy and self-reflection in the literature. This is a narrative review. A literature review was performed using the PubMed, SciVerse Scopus, and Web of Science databases; additional references were found through bibliography reviews of relevant articles published prior to July 2011. The databases were searched for articles containing the following keywords: cognitive behavioural therapy, self-reflection, therapeutic relationship, training, supervision, transference, and countertransference. The review also includes information from monographs referred to by other reviews. We discuss conceptual aspects related to supervision and the role of self-reflection. Self-reflection in therapy is a continuous process which is essential for the establishment of a therapeutic relationship, the professional growth of the therapist, and the ongoing development of therapeutic skills. Recognizing one's own emotions is a basic skill from which other skills necessary for both therapy and emotional self-control stem. Therapists who are skilled in understanding their inner emotions during their encounters with clients are better at making decisions, distinguishing their needs from their clients' needs, understanding transference and countertransference, and considering an optimal response at any time during a session. They know how to handle their feelings so that these correspond with the situation and their response is in the client's best interest. The ability to self-reflect increases the

    Peter Anton Zoettl

    2011-12-01

    Full Text Available Crises and change have affected the Brazilian indigenous population for more than 500 years. While for centuries their struggle against colonialism and the dominant national society had resulted in an ever shrinking population, the last decades have seen an unfamiliar phenomenon: the rise of “new” indigenous tribes in areas which, by the state and public opinion, were long considered as “acculturated”. These “reemerging” Indians, in their pursuit of both legal and actual recognition by authorities and their fellow Non-Indian citizens, face and undergo a peculiar re-elaboration of their “image” as Indians, being torn between romantic ideas of Indianness, and the demands of full integration within national society. Drawing on recent fieldwork experience in northeastern Brazil, the paper discusses how the visual-anthropological method of “participatory video” can be used as a means of reflecting on, and catalyzing, processes of individual and group identity formation of minority groups within a local-global context.

    In this essay I examine the traces of vaudeville performance in the first season of the early American television comedy series I Love Lucy (CBS, 1951–1957), proposing that while sitcom may be regarded as a narratively conservative format, it may also harbour eccentric figures; the funny peculiar. American vaudeville offered a space in which normative heterofemininity was both upheld and subverted. As one of the direct inheritors of that theatrical tradition, early sitcom could embody complex...

    2015-12-01

    Full Text Available Blogging, a mode of electronic journaling, has been identified as an effective means to help pre-service teachers to construct meaning about their experiences. The purpose of this study was to examine pre-service teachers’ reflections about their praxis through blogging and to describe the nature of their growth and development. The use of reflective writing through blogging helped to identify three themes that emerged from the data: (1 validation, (2 prescriptive, and (3 self-assessment. Our findings suggest that blogging facilitated a community of learners that provided support and encouragement. Pre-service teachers’ reflections revealed a focus on the mechanistic aspects of teaching without critically examining the nature of what was observed. However, our findings also suggest that structuring reflective thinking through blogging has the potential to foster a nascent understanding about teaching and learning.

    We wanted to evaluate the effective methods that are appropriate for an endemic area of thyroid disease and to compare the differences of cytologic diagnostic rates with and without using a peculiar smear technique. We analyzed the incidence rate of insufficient results, complications and the total procedure times of 1,126 thyroid nodules in 776 patients who underwent US-FNAB (ultrasonography-guided fine-needle aspiration biopsy) from January to December 2005. We compared the diagnostic rate between the two groups; the groups' tests were performed with a peculiar smear technique (Group A, n 313) or with a ventional smear technique (Group B, n = 250). According to the size of the thyroid nodule, the incidence rate of an insufficient result on US-FNAB and the mean total procedure time for 1126 thyroid nodules in 776 patients were measured as 16.9% (52/308) and 208 seconds for nodules under 0.5 cm, 9.8% (30/306) and 160 seconds for nodules between 0.5 cm-10 cm, and 6.0% (30/504) and 134 seconds for nodules over 1.0 cm. These 776 patients showed no significant complication, except for mild pain. In Group A, the incidence rate of an insufficient result was calculated as 15.1% (14/93) for the group with nodules under 0.5 cm, 5.3% (5/95) for the group with nodules between 0.5 cm-1.0 cm, 4.8% (6/125) for the group with nodules over 1.0 cm, and 8.0% (25/313) for the total A Group. In Group B, the incidence rate of an insufficient result was measured as 33.3% (15/45) for the group with nodules under 0.5 cm, 28.1% (25/89) for the group with nodules between 0.5 cm-1.0 cm, 21.4% (24/112) for the group with nodules over 1.0 cm, and 25.7% (63/245) for the total B group. There was a statistically significant correlation between the rate of an insufficient result and the peculiar smear technique or the size of the thyroid nodule. We consider that US-FNAB is very simple, safe and accurate diagnostic method for thyroid nodules, and US-FNAB with a peculiar smear technique is able to

    Full Text Available This article seeks to determine some of the peculiarities of the economic growth in the countries from the Economic Community of West African States (ECOWAS. Thus, the study is based on the country approach and uses econometric regression tests. In fact, in the context of the determination of the real GDP per capita growth rate of the countries in this region during the period 1987-2014, the results obtained show that it is still weak and unstable. Moreover, the weak convergence that has only been observed beginning with 2008 feeds the hope that ECOWAS can truly improve its level of development despite the heterogeneous nature of the countries. In order to overcome these difficulties, improving the socio-economic performance through the growth rate of real GDP per capita represents, among others, a necessity in relation to economic policy decisions.

  12. Medial prefrontal cortex subserves diverse forms of self-reflection.

    Jenkins, Adrianna C; Mitchell, Jason P

    2011-01-01

    The ability to think about oneself--to self--reflect--is one of the defining features of the human mind. Recent research has suggested that this ability may be subserved by a particular brain region: the medial prefrontal cortex (MPFC). However, although humans can contemplate a variety of different aspects of themselves, including their stable personality traits, current feelings, and physical attributes, no research has directly examined the extent to which these different forms of self-reflection are subserved by common mechanisms. To address this question, participants were scanned using functional magnetic resonance imaging (fMRI) while making judgments about their own personality traits, current mental states, and physical attributes as well as those of another person. Whereas some brain regions responded preferentially during only one form of self-reflection, a robust region of MPFC was engaged preferentially during self-reflection across all three types of judgment. These results suggest that--although dissociable--diverse forms of self-referential thought draw on a shared cognitive process subserved by MPFC.

  13. Computation of Mach reflection from rigid and yielding surfaces

    Buckingham, A.C.; Wilson, S.S.

    1976-01-01

    The present discussion centers on a theoretical description of one aspect of the irregular or Mach reflection from solid surfaces. The discussion is restricted to analytical considerations and some preliminary results using model approximations to the surface interaction phenomena. Currently, full numerical simulations of the irregular reflection surface interaction dynamics have not been obtained since the method is still under development. Discussion of the numerical method is, therefore, restricted to some special procedures for the gas-solid surface boundary dynamics. The discussion is divided into an introductory section briefly describing a particular Mach reflection process. Subsequently, some of the considerations on boundary conditions are submitted for numerical treatment of the gas-solid interface. Analysis and discussion of a yielding solid surface subjected to impulsive loading from an intense gas shock wave follows. This is used as a guide for the development of the numerical procedure. Mach reflection processes are then briefly reviewed with special attention for similitude and singular perturbation features

    Full Text Available The Pedregal granite outcrops in the Central Iberian Zone, northern Portugal, in the eastern border of a synorogenic variscan granite-migmatite complex sub-concordant with the regional metamorphic structures. It is a granitoid (ca. 3 km2 with an elongated NW-SE shape intruded in staurolite-micaschist and banded gneiss-migmatite rocks, with local igneous breccias in the contact. The country rocks belong to a metapelitic and metasammitic sequence of Edicarian-Cambrian age, known as the “Complexo Xisto-Grauváquico” (CXG which shows a main regional foliation with a NW-SE to NNW-SSE direction. The Pedregal granite is peraluminous (its A/CNK parameter ranges from 1.18 to 1.62, with a magnesian and alkali to alkali-calcic signature. The peculiar features of the granite are high contents of Zr (389 to 435 ppm and a LREE flat pattern, which are uncommon characteristics for granitic rocks, as well as the corroded shape of the biotite, and the large amount of secondary muscovite. These peculiar features distinguish it from the adjacent synorogenic granites. The field, petrographical and chemical features of the Pedregal granite are in accordance with a second phase of partial melting of a residuum, depleted by melt segregation during a first melting episode with the involvement of peritectic garnet and abundant residual biotite with LREE- and Zr-bearing accessory minerals. Besides, the intrusive character of the granite, and the presence of metasedimentary xenoliths point out to a secondary diatexite.El granito de Pedregal aflora en la Zona Centro-Ibérica, en el norte de Portugal, en el borde oriental de un complejo granito-migmatítico sinorogénico varisco, subconcordante con las estructuras metamórficas regionales.

    Full Text Available The aim was to study the peculiarities of rotavirus infection in children with various genotypes of the lactase gene LCT. Molecular genetic studies of LCT13910 gene polymorphism by polymerase chain reaction with electrophoretic detection were determined in the Institute of Genetic and Immunological basis of pathology and pharmacogenetics of "Ukrainian Medical Stomatological Academy", Poltava. According to the results of molecular genetic studies, all children were divided into three groups: the first group included 45 children with genotype C/C-13910, the second - 22 children with genotype C/T-13910, the third - 3 chil¬d¬ren with genotype T/T-13910. It is proved that in infants with rotavirus, the most common (63% is genotype C/C-13910 of LCT gene. It is shown that a less severe form of the disease, which in most cases occurs without fever, a less duration of vomiting syndrome, a high incidence of respiratory syndrome, a less duration of illness are the peculiarities of rotavirus infection in children with genotype C/C-13910 LCT gene. Tendency to severe course with febrile fever, severe diarrhea, a high frequency of occurrence of expressed ketone blood syndrome, longer duration of disease may be considered to be features of rotavirus infection course in children with genotype C/T-13910 LCT gene.

  1. Functions and generality of logic reflections on Dedekind's and Frege's logicisms

    CERN Document Server

    Benis-Sinaceur, Hourya; Sandu, Gabriel

    2015-01-01

    This book examines three connected aspects of Frege's logicism: the differences between Dedekind's and Frege's interpretation of the term 'logic' and related terms and reflects on Frege's notion of function, comparing its understanding and the role it played in Frege's and Lagrange's foundational programs. It concludes with an examination of the notion of arbitrary function, taking into account Frege's, Ramsey's and Russell's view on the subject. Composed of three chapters, this book sheds light on important aspects of Dedekind's and Frege's logicisms. The first chapter explains how, although he shares Frege's aim at substituting logical standards of rigor to intuitive imports from spatio-temporal experience into the deductive presentation of arithmetic, Dedekind had a different goal and used or invented different tools. The chapter highlights basic dissimilarities between Dedekind's and Frege's actual ways of doing and thinking. The second chapter reflects on Frege's notion of a function, in comparison with ...

  2. Prerequisites for sustainable care improvement using the reflective team as a work model.

    2014-01-01

    Several work models for care improvement have been developed in order to meet the requirement for evidence-based care. This study examines a work model for reflection, entitled the reflective team (RT). The main idea behind RTs is that caring skills exist among those who work closest to the patients. The team leader (RTL) encourages sustainable care improvement, rooted in research and proven experience, by using a lifeworld perspective to stimulate further reflection and a developmental process leading to research-based caring actions within the team. In order to maintain focus, it is important that the RTL has a clear idea of what sustainable care improvement means, and what the prerequisites are for such improvement. The aim of the present study is, therefore, to explore the prerequisites for improving sustainable care, seeking to answer how RTLs perceive these and use RTs for concrete planning. Nine RTLs were interviewed, and their statements were phenomenographically analysed. The analysis revealed three separate qualitative categories, which describe personal, interpersonal, and structural aspects of the prerequisites. In the discussion, these categories are compared with previous research on reflection, and the conclusion is reached that the optimal conditions for RTs to work, when focussed on sustainable care improvement, occur when the various aspects of the prerequisites are intertwined and become a natural part of the reflective work.

    Investigation results on the lithologic heterogeneity of the productive horizon in the Shatlyk gas field are cited. The work was performed by a set of commercial and geophysical procedures involving the method of spontaneous polarization potentials, side electrical sounding with five probes, cavernometry, microsounding, side logging and radiometry (neutron gamma method and gamma method). The structural peculiarity of the Shatlyk horizon was shown to possibly lead to non-uniform movement of seam waters during drilling and to flooding of wells

    Endothelial function and arterial stiffness are known to be altered in preeclamptic pregnancies. Previous studies have shown conflicting results regarding the best technique for assessing vascular function in pregnancy. In this study, we made a comprehensive evaluation of in vivo vascular function [including flow-mediated dilatation (FMD), peripheral arterial tonometry (PAT), and arterial stiffness] in preeclamptic patients and compared them with normal pregnancies. In addition, we assessed the relation between vascular function and systemic inflammation. Fourteen patients with preeclampsia (PE) and 14 healthy pregnant controls were included. Endothelial function was determined by FMD and PAT and arterial stiffness by carotid-femoral pulse-wave velocity and augmentation index. Systemic inflammation was assessed using mean platelet volume (MPV) and neutrophil-lymphocyte ratio (NLR). The reactive hyperemia index, assessed using PAT, is decreased at the third trimester compared with the first trimester in a normal, uncomplicated pregnancy ( P = 0.001). Arterial stiffness is significantly higher in PE versus normal pregnancy ( P function, obtained by FMD, is deteriorated in PE versus normal pregnancy ( P = 0.015), whereas endothelial function assessment by PAT is improved in PE versus normal pregnancy ( P = 0.001). Systemic inflammation (MPV and NLR) increases during normal pregnancy. FMD and PAT are disturbed in PE. Endothelial function, assessed by FMD and PAT, shows distinct results. This may indicate that measurements with FMD and PAT reflect different aspects of endothelial function and that PAT should not be used as a substitute for FMD as a measure of endothelial function in pregnancy.

    The effect of natural conditions on the USSR territory connected with peculiar types of soil on the behaviour of radionuclides fallen from stratosphere is considered. Characteristics of tundra, taiga partially-wooded steppe, step.oe, mountain and semi-desert zones are presented. Peculiarities of soils in different geographical zones of the USSR conditioned by various properties and compositions have a significant effect on 90 Sr and especially 137 Cs migration intensity from the soil into plants and organisms of animals through biological chains. The administration of radionuclides in the ration with food stuffs obtained on the surface of reservoirs where zonality low is also rightful, is studied. It is established that indexes of 90 Sr and 137 Cs buildup in tissues of hydrobionts are in reverse dependence on calcium and potassium content in water. Therefore, maximum levels of 90 Sr and 137 Cs buildup in fish is characteristic of zones with the low content of these elements. The degree of water mineralization in ponds has a clear zonality which increases in the direction from the North to the South. The degree of pond well-drained nature is of great importance

    Huang, Hui-Ju

    The study examined the nature of how children make sense of phenomena in the area of genetics and inheritance. I proposed the phrase, way of understanding to capture a unified entity which children use to make sense of phenomena. The methodology was semi-structured probing interviews with six sixth grade students. Seven specific ways of understanding were discussed in the results section. Overall, the study described and discovered children's ways of understanding in terms of five aspects: cognitive aspects, affective aspects, social aspects, playfulness, and mode of awareness. Students' propositional knowledge, a holistic view of looking at how people resemble each other, syntactic knowledge, and an extension of rational explanations belonged to the cognitive aspects. Four categories of affective expressions were: an enjoyment of thinking and learning, a special feeling about the instructional activity, a deep personal involvement, and an anxiety in finding correct answers. Two types of social context were identified, one had somewhat of a connection to the science world, and the other did not have much of an scientific tie. The playfulness and the mode of awareness were two emerging aspects through the study. The playfulness represented the spontaneity, freedom, and sense of fun associated with the social interaction activity, such as the playfulness in expressing ideas to others. The modes of awareness included two types of metacognition, one was a conscious reflection on one's cognitive abilities, and the other was a continuous process of monitoring knowledge. In addition, the importance of considering language aspect in science learning was an emerging issue. Students' talking about genetics was embedded in the larger framework of social relationships and social institutions. Their social identify might influence the development of concepts, ways of talking and science learning. The study reflects the richness of children's sense-making processes

    Leukocyte telomere length and serum levels of high-molecular-weight adiponectin and dehydroepiandrosterone-sulfate (DHEA-S) were assessed in association with nutrition and performance status (PS) in Japanese centenarians. Twenty-three centenarians (five men, 18 women) were classified according to their PS 1 (nearly fully ambulatory, n = 2), 2 (in bed less than 50% of daytime, n = 10), 3 (in bed greater than 50%, n = 6), and 4 (completely bedridden, n = 5). Leukocyte telomere length was determined by the hybridization protection assay, and the adiponectin and DHEA-S levels were measured by chemiluminescent enzyme immunoassay. Among variables of PS, body mass index (BMI), albumin, adiponectin, DHEA-S, and telomere length, there were significant correlations between PS and albumin ( r = -.694, p r = .522, p r = -.574, p r = .530, p r = -.632, p < .01). It was indicated that the short leukocyte telomere was associated with poor PS and cancer development and that the adiponectin or DHEA-S was associated with adiposity or nutritional status. Despite a small number of subjects, these biomarkers seemed to reflect distinct aspects of longevity in Japanese centenarians.

    To reveal the peculiarities of medical sociology introducing the application of social theories in analyzing public health and medicine. Comparative and descriptive analysis of scientific references found and current situation. During the last decade of the 20th century, the discussions about the sociology of health and medicine as separate discipline and its practical applications became more active. Main factors determined the growing importance of discipline were institutionalization of medicine and health care, changing patterns in doctor-patient relationships, different health perceptions, understanding of the influence of social factors on health, cardinal changes in the area of health technologies, consumeristic attitude towards health, appearance of market relationships within health care, and other global phenomena. In sociology, usual social theories such as structural functionalism, conflict, symbolic interaction, poststructuralism, feminist often attempt to explain the changes within health care. There is a relation of medical sociology and other types of sociology having common areas with medicine and health being analyzed in the article; social theories and their application in the field of health and medicine are being introduced attempting to explain the ongoing social changes in both Lithuania and the world. More and more attention in various areas of medical activities is being paid to the social aspects (both individual and society levels) of these activities, and there is a shift from applied sociology towards medical one. Despite the cessations of the development of medical sociology as separate branch of sciences, the researches of recent years are demonstrating obvious approaching modern research issues and methods, which do exist in contemporary world. Such tendencies show the prompt approaching of the academic community of Lithuania the general scientific standards which are dominating in the globalization-effected world.

  15. Ethical reflection and psychotherapy.

    Vyskocilová, Jana; Prasko, Jan

    2013-01-01

    Theories of ethics and ethical reflection may be applied to both theory and practice in psychotherapy. There is a natural affinity between ethics and psychotherapy. Psychotherapy practice is concerned with human problems, dilemmas and emotions related to both one's own and other people's values. Ethics is also concerned with dilemmas in human thinking and with how these dilemmas reflect other individuals' values. Philosophical reflection itself is not a sufficient basis for the ethics of psychotherapy but it may aid in exploring attitudes related to psychotherapy, psychiatry and health care. PubMed, Web of Science and Scopus databases were searched for articles containing the keywords "psychotherapy", "ethics", "therapeutic relationship" and "supervision". The search was conducted by repeating the terms in various combinations without language or time restrictions. Also included were data from monographs cited in reviews. The resulting text is a review with conclusions concerning ethical aspects of psychotherapy. The ability to behave altruistically, sense for justice and reciprocity and mutual help are likely to be genetically determined as dispositions to be later developed by upbringing or to be formed or deformed by upbringing. Early experiences lead to formation of ethical attitudes which are internalized and then applied to both one's own and other people's behavior. Altruistic behavior has a strong impact on an individual's health and its acceptance may positively influence the pathophysiological mechanisms underlying numerous diseases. Ethical theory and reflection, however, may be applied to both theory and practice of psychotherapy in a conscious, targeted and thoughtful manner. In everyday practice, psychotherapists and organizations must necessarily deal with conscious conflicts between therapeutic possibilities, clients' wishes, their own as well as clients' ideas and the real world. Understanding one's own motives in therapy is one of the aims of a

    Full Text Available É sabido que o envelhecimento da população do mundo durante o século XX e no início deste novo século constitui um desafio de primeira ordem para as nações, especialmente no campo socioeconômico. Um aspecto importante do envelhecimento populacional global é que, para grupos de idade mais avançada, a prevalência das doenças degenerativas também é maior, incluindo as doenças malignas. No universo de pacientes portadores de câncer, por outro lado, metade destes receberá radioterapia em algum momento de sua doença e suas características individuais podem influenciar, de alguma forma, o prognóstico, a indicação e as doses diárias de prescrição dos tratamentos. Neste contexto, a assistência à saúde do idoso portador de câncer deve ser vista como um importante desafio, principalmente devido a dois fatores: uma maior procura de tratamentos, em termos quantitativos, e características fisiológicas peculiares a esta população, que podem influenciar na tomada de decisões terapêuticas. Esta revisão propõe uma discussão sobre alguns aspectos relevantes tanto da fisiologia dos idosos, que pode influenciar o curso do tratamento irradiante, quanto de alguns avanços técnicos da radioterapia, que podem, por sua vez, beneficiar estes pacientes, oferecendo menor toxicidade e maior eficiência e rapidez, por exemplo.It is known that the aging of the world population during the twentieth century and the beginning of this new century is a first-order challenge for nations, especially in the socio-economic field.

    Full Text Available Purpose. To review scientific sources on the morphological and ecophysiological peculiarities of the transition of early sturgeon fry (Acipenseridae to artificial formulated feeds. To summarize the biotechnological fundamentals of the use of artificial formulated feeds in the conditions of recirculating aquaculture systems (RAS. Findings. The transition of early sturgeon fry to artificial formulated feeds is one of the most difficult stages of their rearing, even under controlled conditions of RAS. The review contains the description of the peculiarities of sturgeon embryogenesis, their behavior and morpho-physiological changes at this stage of their development. It contains main requirements for the rearing of sturgeon larvae in RAS. We showed that the ultimate refuse from natural (live or frozen forage organisms is not advisable; the optimum is their combination with artificial feeds with gradual predominance of the latters. We provided the schemes of their feeding based on the combination of natural and artificial feeds. We reviewed the most common biologically active supplements, which contributed to better feed digestion during the periods of the transition to exogenous feeding. We highlighted the effect of feeding with brine shrimp nauplii enriched with polyunsaturated fatty acids on the growth and development of early sturgeon fry. Practical value. The array of the summarized information will be important for scientists who study the peculiarities of the transition of early sturgeon fry to artificial formulated feeds in RAS. The data on the biotechnologies of rational feeding of early sturgeon fry in RAS in this period are important in the conditions of continuous search for the most effective replacement of live forage organisms and reduction of fish fry mortality in postembryogenesis.

    1981-11-01

    Radiotherapy in cervical carcinoma patients is frequently followed by severe intestinal injuries which serve as prerequisites for the penetration of endotoxins of intestinal microflora into the systemic circulation. Peculiarities of possible development of endotoxemia were studied in 45 women with cervical carcinoma (Stages 2, 3). Radiotherapy was performed by routine methods (long-focus irradiation with subsequent intracavitary irradiation, or simultaneous long-focus and intracavitary irradiation). The presence of bacterial endotoxins in the patients blood was revealed by the testing of the lethal effect after intraperitoneal administration of the examined blood (0.1 ml) to random-bred albino mice simultaneously with actinomycin D(10 ..mu..g/mouse) that sharply increases the sensitivity of animals to a toxic effect of endotoxins. It has been established that involvement of the intestine in irradiation is followed by endotoxemia regardless of radiotherapeutic methods. The degree of severity of endotoxemia developing in the first half of a radiotherapeutic course depends on a radiation dose. On reaching a certain level, endotoxemia preserves its severity up to the end of irradiation and at early time after its completion.

  2. Accuracy and efficiency in the binary star reflection effect

    International Nuclear Information System (INIS)

    Wilson, R.E.

    1990-01-01

    The geometric and irradiation heating problems for the binary star reflection effect theory are developed in terms of equipotential level surfaces and are sufficiently general so as to include eccentric orbits and nonsynchronous (even centrifugally limited) rotation and to treat multiple reflection. The requisite physics, mathematics, and logic are then presented and the computations are organized so that a given quantity is computed only as often as necessary, emphasizing the distinction between local surface quantities and aspect-related quantities. The local geometric, bolometric, and wavelength-specific quantities are grouped for storage according to how often they need to be recomputed. Some tests of a computer program based on this reflection model are given in the form of graphs in which program results are compared to a special exact case, and with results from an earlier program. The new program gives intuitively reasonable output for all tests, and the tests give an idea of how accurate the old program is, adopting the detailed reflection computations of the new program as a standard for comparison. A table is given which shows the convergence of the multiple reflection computations to a constant distribution of surface effective temperature. 11 refs

  4. Strong late-time circumstellar interaction in the peculiar supernova iPTF14hls

    Andrews, Jennifer E.; Smith, Nathan

    2018-06-01

    We present a moderate-resolution spectrum of the peculiar Type II supernova (SN) iPTF14hls taken on day 1153 after discovery. This spectrum reveals the clear signature of shock interaction with dense circumstellar material (CSM). We suggest that this CSM interaction may be an important clue for understanding the extremely unusual photometric and spectroscopic evolution seen over the first 600 d of iPTF14hls. The late-time spectrum shows a double-peaked intermediate-width H α line indicative of expansion speeds around 1000 km s-1, with the double-peaked shape hinting at a disc-like geometry in the CSM. If the CSM were highly asymmetric, perhaps in a disc or torus that was ejected from the star 3-6 yr prior to explosion, the CSM interaction could have been overrun and hidden below the SN ejecta photosphere from a wide range of viewing angles. In that case, CSM interaction luminosity would have been thermalized well below the photosphere, potentially sustaining the high luminosity without exhibiting the traditional observational signatures of strong CSM interaction (narrow H α emission and X-rays). Variations in density structure of the CSM could account for the multiple rebrightenings of the light curve. We propose that a canonical 1 × 1051 erg explosion energy with enveloped CSM interaction as seen in some recent SNe, rather than an entirely new explosion mechanism, may be adequate to explain the peculiar evolution of iPTF14hls.

    2017-01-01

    ABSTRACT This study was conducted to identify the source of animal meat based on the peculiarities of protein intrinsic disorder distribution in mitochondrial cytochrome b (mtCyt-b). The analysis revealed that animal and avian species can be discriminated based on the proportions of the two groups of residues, Leu+Ile, and Ser+Pro+Ala, in the amino acid sequences of their mtCyt-b. Although levels of the overall intrinsic disorder in mtCyt-b is not very high, the peculiarities of disorder distribution within the sequences of mtCyt-b from different species varies in a rather specific way. In fact, positions and intensities of disorder/flexibility “signals” in the corresponding disorder profiles are relatively unique for avian and animal species. Therefore, it is possible to devise a set of simple rules based on the peculiarities of disorder profiles of their mtCyt-b proteins to discriminate among species. This intrinsic disorder-based analysis represents a new technique that could be used to provide a promising solution for identification of the source of meats. PMID:28331777

    The flipped classroom is an instruction method that has gained momentum during the last years due to technological advances allowing the online sharing of teaching material and learning activities. Bishop and Verleger defined the flipped classroom as “...an educational technique that consists...... of two parts: interactive group learning activities inside the classroom, and direct computer-based individual instruction outside the classroom” (Bishop & Verleger, 2013). So far, research on flipped classroom has mostly concentrated on student perceptions, engagement and achievement level, e...... course in order to adjust it to the flipped classroom model. We have also seen that these considerations have forced teachers to also reconsider the learning objectives of specific activities. Another aspect that promoted reflection was the production of video lectures. Finally, teachers reflected...

    Full Text Available Customer loyalty - is a voluntary user solution for a long time to build relationships with the company. Loyalty is the user's desire for a long time to continue their relationship with a particular company, because loyal customers are those who purchase goods/services of the company from time to time. Loyalty can be treated as a customer desire, willingness to be a regular customer for a long time, buying and using the goods of the chosen companies by recommending them to friends and colleagues. Loyalty can be seen as a multi-dimension, covering behavioral and positional components, where positional aspect reflects customers' approach to business, while the behavioral dimension reveals a frequent and regular shopping, purchase quantity, size, range, availability, etc.

    2014-05-01

    Full Text Available The paper deals with investigation of application peculiarities of ellipsometry methods and UF spectrophotometry at mechanical and chemical processing of optical engineering surface elements made of quartz glass. Ellipsometer LEF–3M–1, spectrophotometer SF–26 and interferometer MII–4 are used as experiment tools; they obtain widely known technical characteristics. Polarization characteristics of reflected light beam were measured by ellipsometry method; spectrophotometry method was used for measuring radiation transmission factor in UF spectrum area; by interference method surface layer thickness at quartz glass etching was measured. A method for HF–sectioning of inhomogeneous surface layer of polished quartz glass is developed based on ellipsometry equation for reflection system «inhomogeneous layer – inhomogeneous padding». The method makes it possible to carry out the measuring and analysis of optical characteristics for inhomogeneous layers system on inhomogeneous padding and to reconstruct optical profile of surface layers at quartz glass chemical processing. For definition of refractive index change along the layer depth, approximation of experimental values for polarization characteristics of homogeneous layers system is used. Inhomogeneous surface layer of polished quartz glass consists of an area (with thickness up to 20 nm and layer refractive index less than refractive index for quartz glass and an area (with thickness up to 0,1 μm and layer refractive index larger than refractive index for quartz glass. Ellipsometry and photometry methods are used for definition of technological conditions and optical characteristics of inhomogeneous layers at quartz glass chemical processing for optical elements with minimum radiation losses in UF spectrum area.

    The article investigates the disintegration of perlite production waste in a vortex jet mill; the regularities of milling were established. Binding compositions were obtained at different ratios of cement vs. perlite sand production waste in the vortex jet mill in various milling regimes. The peculiarities of milling processes were studied, and technological and physicomechanical properties of the binding compositions were determined as well. The microstructure of the cement stones made of activated Portland cement and binding compositions in the vortex jet mill was elucidated by electron microscopy. The open pores of the cement-binding compositions prepared using perlite fillers were found to be filled by newgrowths at different stages of collective growth. The microstructure of the binding compositions is dense due to rationally proportioned composition, effective mineral filler— perlite waste — that creates additional substrates for internal composite microstructure formation, mechanochemical activation of raw mixture, which allows obtaining composites with required properties.

    2014-01-01

    Neurofeedback training procedures designed to alter a person's brain activity have been in use for nearly four decades now and represent one of the earliest applications of brain-computer interfaces (BCI). The majority of studies using neurofeedback technology relies on recordings of the electroencephalogram (EEG) and applies neurofeedback in clinical contexts, exploring its potential as treatment for psychopathological syndromes. This clinical focus significantly affects the technology behind neurofeedback BCIs. For example, in contrast to other BCI applications, neurofeedback BCIs usually rely on EEG-derived features with only a minimum of additional processing steps being employed. Here, we highlight the peculiarities of EEG-based neurofeedback BCIs and consider their relevance for software implementations. Having reviewed already existing packages for the implementation of BCIs, we introduce our own solution which specifically considers the relevance of multi-subject handling for experimental and clinical trials, for example by implementing ready-to-use solutions for pseudo-/sham-neurofeedback. © 2013.

    2008-01-01

    Electro - technical devices are considered as the most prospective use for high temperature superconductors. For such devices the overload currents due to faults in grids are the operational reality. In these cases the fault currents may forcibly go to superconductors being sometimes dozens times more than the critical currents of HTS. Overloads are the working modes for fault current limiters also. To understand the behavior of HTS devices at overloads it is important to study voltage-current characteristics (VCC) of basic HTS tapes in real cooling conditions. The knowledge of VCC permits to model and to simulate properly HTS devices behavior at overloads. We performed the study of VCC of several HTS tapes at currents several times more than their critical ones. Both, 1-G and 2-G tapes were tested. There were found peculiarities or 'spikes' on VCC at rising currents that vanished at decaying currents. It was shown that such peculiarities are determined by the change of cooling conditions from the convective heat exchange to the nucleate boiling. Nucleate boiling activation and development times were determined. Their dependencies on heat release were measured. The data obtained can be used in simulation of heating of real superconducting devices at overload conditions

    Based on a peculiar property of the Fifth Unstable Nuclide Series (FUNS) in developing stage, namely the transformation rate of parent fuel- 238 U consumption to fission production being increased with the fuel's reactor core life, it was shown that the used fuel taken out from the reactor core of PWR could be used again as PWR fuel, and the post processing for the used fuel needed only to de-contaminate the fission products from the used fuel and then to rebuild it into its normal form. Scheme A discussed the condition of using such rebuilt used fuel in PWR. Another peculiar property of FUNS is characterized by the fact that the equilibrium saturate concentrations of the derived nuclides in FUNS are different for different types of reactor. It is well known that the saturate concentration of 239 Pu in PWR is much larger than that in HWR. Scheme B i.e. a method of using the rebuilt used fuel from PWR to replace the natural uranium fuel for HWR was discussed

    Traditional irrigation, as part of the ancient agricultural practices in northern Ethiopia (Tigray), has persisted for long time since 500 B.C.,while many newly introduced irrigation projects have usually failed there. The main objective of this study is thus to investigate the peculiarities pertinent to irrigation management and those having contributed for the persistence of traditional irrigation practices for a long period of time. The experience gained from such areas can definitely help make irrigation management system of new irrigation schemes sustainable. Betmera-Hiwane, one of the ancient traditional irrigation areas in Tigray region, was selected for the field study. Direct observations through field visits accompanied by interviews to farmers, local officials, local knowledgeable individuals and higher officials were made. After analyzing the collected primary and secondary information, the main peculiarities that contributed to the persistence of traditional irrigation areas were identified, and they are: the presence of communally constructed local rules, locally designed hydraulic control structures, ownership feeling of the irrigators and accountability of water distributors to the irrigation management, the culture for mobilizing communal resources and the culture of self-initiating local water management strategies.

  20. Peculiarities of the Third Natural Frequency Vibrations of a Cantilever for the Improvement of Energy Harvesting

    Directory of Open Access Journals (Sweden)

    Vytautas Ostasevicius

    2015-05-01

    Full Text Available This paper focuses on several aspects extending the dynamical efficiency of a cantilever beam vibrating in the third mode. A few ways of producing this mode stimulation, namely vibro-impact or forced excitation, as well as its application for energy harvesting devices are proposed. The paper presents numerical and experimental analyses of novel structural dynamics effects along with an optimal configuration of the cantilever beam. The peculiarities of a cantilever beam vibrating in the third mode are related to the significant increase of the level of deformations capable of extracting significant additional amounts of energy compared to the conventional harvester vibrating in the first mode. Two types of a piezoelectric vibrating energy harvester (PVEH prototype are analysed in this paper: the first one without electrode segmentation, while the second is segmented using electrode segmentation at the strain nodes of the third vibration mode to achieve effective operation at the third resonant frequency. The results of this research revealed that the voltage generated by any segment of the segmented PVEH prototype excited at the third resonant frequency demonstrated a 3.4–4.8-fold increase in comparison with the non-segmented prototype. Simultaneously, the efficiency of the energy harvester prototype also increased at lower resonant frequencies from 16% to 90%. The insights presented in the paper may serve for the development and fabrication of advanced piezoelectric energy harvesters which would be able to generate a considerably increased amount of electrical energy independently of the frequency of kinematical excitation.

    The longitudinal study aims to expand what is known about the costs and benefits of narrating stressful experiences by exploring changes in rumination within the narrative process and comparing it to changes in self-reflection. Rumination (e.g., brooding, self-criticism, and negative emotions) and self-reflection were measured in stress narratives of 56 college students. There were several goals: (1) examine changes in narrative rumination and narrative self-reflection over 3 days of writing, (2) examine the relations among the changes in narrative rumination variables and narrative self-reflection and (3) examine how changes in narrative rumination and narrative self-reflection relate to multiple measures of psychological functioning. Overall, individuals increased self-reflection over the 3-day writing task. Individuals who increased ruminative brooding across the 3 days of writing showed lower ego identity development (short term and long term) and self-esteem (short term), while increased self-criticism was positively correlated with identity distress (short term). Implications of the different aspects of narrative rumination, specifically in the context of stressful experiences, are discussed.

    Full Text Available The article considers the peculiarities of the organizational behavior of Russian doctors and conditions of its formation determined by the development of the national health care system in the Russian and Soviet periods. The authors analyze the changes in the national health care system since the Semashko model that was created in the first years of Soviet power and evolved in the post-war period into a multi-level system of medical care with clearly differentiated structure of services and later into the Soviet model focusing on specialized outpatient care and large staff of narrowly focused specialists; from the first private medical clinics in the late 1980s to the decline of the sphere in the 1990s and the reforms of the beginning of the XXI century. All stages of the national health care system evolution are the determinants of the Russian doctors’ organizational behavior changes, the crisis of professional ethics, the transformations of the professional consciousness from the ideas of service and medical care to the principle of providing medical services. The authors also consider some implications of the national project ‘Health’ in the contemporary Russia.

    Full Text Available Stress-induced cell surface expression of MHC class I-related glycoproteins of the MIC and ULBP families allows for immune recognition of dangerous “self cells” by human cytotoxic lymphocytes via the NKG2D receptor. With two MIC molecules (MICA and MICB and six ULBP molecules (ULBP1–6, there are a total of eight human NKG2D ligands (NKG2DL. Since the discovery of the NKG2D–NKG2DL system, the cause for both redundancy and diversity of NKG2DL has been a major and ongoing matter of debate. NKG2DL diversity has been attributed, among others, to the selective pressure by viral immunoevasins, to diverse regulation of expression, to differential tissue expression as well as to variations in receptor interactions. Here, we critically review the current state of knowledge on the poorly studied human NKG2DL ULBP4. Summarizing available facts and previous studies, we picture ULBP4 as a peculiar ULBP family member distinct from other ULBP family members by various aspects. In addition, we provide novel experimental evidence suggesting that cellular processing gives rise to mature ULBP4 glycoproteins different to previous reports. Finally, we report on the proteolytic release of soluble ULBP4 and discuss these results in the light of known mechanisms for generation of soluble NKG2DL.

    The study of peculiarities of hypergene zone evolution at the uranium-phosphate deposit has been carried out to clarify possibilities of qualitative and quantitative estimation of primary ores as to their outputs at search works. Bed-like deposit of phosphorites occurs together with ore-containing limestones and at considerable length it comes out at the day surface. Hypergenously unchanged phosphorites present grey microcrystallic carbonate-apatite ores, comprising fluoroapatite (60-80%) and calcite. It is shown, that the greater part of uranium in unchanged ores is bound with U- and Th containing fluoroapatite, U amounts being low

    2014-06-02

    Quasi-ordered moth-eye arrays were fabricated in Si using a colloidal lithography method to achieve highly efficient, omni-directional transmission of mid and far infrared (IR) radiation. The effect of structure height and aspect ratio on transmittance and scattering was explored experimentally and modeled quantitatively using effective medium theory. The highest aspect ratio structures (AR = 9.4) achieved peak transmittance of 98%, with >85% transmission for λ = 7-30 μm. A detailed photon balance was constructed by measuring transmission, forward scattering, specular reflection and diffuse reflection to quantify optical losses due to near-field effects. In addition, angle-dependent transmission measurements showed that moth-eye structures provide superior anti-reflective properties compared to unstructured interfaces over a wide angular range (0-60° incidence). The colloidal lithography method presented here is scalable and substrate-independent, providing a general approach to realize moth-eye structures and anti-reflection in many IR-compatible material systems.

    Full Text Available We consider diverse deformed Bose gas models (DBGMs focusing on distributions and correlations of any order, and also on deformed thermodynamics. For so-called μ -deformed Bose gas model ( μ -DBGM, main thermodynamic aspects are treated: total number of particles, deformed partition function, etc. Using a geometric approach, we confirm the existence of critical behavior—Bose-like condensation; we find the critical temperature T c ( μ depending on μ so that T c ( μ > T c ( Bose for μ > 0 . This fact and other advantages of μ -DBGM relative to the usual Bose gas, e.g., stronger effective inter-particle attraction (controlled by the parameter μ , allow us to consider the condensate in μ -DBGM as a candidate for modeling dark matter. As another, quite successful application we discuss the usage of the two-parameter ( μ ˜ , q -deformed BGM for effective description of the peculiar (non-Bose like behavior of two-pion correlations observed in the STAR experiment at RHIC (Brookhaven. Herein, we point out the transparent role of the two deformation parameters μ ˜ and q as being responsible for compositeness and (effective account of interactions of pions, respectively.

    2013-04-01

    Full Text Available The aim of the paper is to characterize the communicative peculiarities of the interpretative-deliberative style in pedagogical discourse. The object of the study is interpretative-deliberative style viewed as one of the communication forms in pedagogical discourse; the subject of the analysis is the stratagem and tactics characteristics of the interpretative-deliberative communicative style. Descriptive and analytical as well as stylistic and discourse analysis methods are employed. The author reveals the most prevalent strategies–explanatory, interpretative and deliberative–employed in communicative interaction in situations of educative persuasion. The communicative characteristics of the analyzed style are: a rational type of the communicative action, a trust-based tone and the emotional involvement of the communication participants. The results can be used for clarifying specifics of speech behavior in educative communication as well as for comparing styles of educative communication in different enthnocultural traditions.

This feature of bipartite quantum systems is different from the previously observed phenomenon of entanglement sudden birth. It is found that the states of reservoirs first become bound entangled, thus exhibiting entanglement sudden birth, consequently followed by the sudden birth of distillability, and it is shown that whenever distillability is lost abruptly from principal system, it also necessarily appears abruptly among reservoirs' degrees of freedom. This surprising observation reflects yet another peculiarity of dynamical aspects of quantum entanglement

    Every language has its peculiar problems of meaning for the foreign learner. In the English language, some of the biggest yet most fascinating problems are concentrated in the area of the finite verb phrase: in particular, tense, aspect, mood and modality. Meaning and the English Verb describes these fields in detail for teachers and advanced students of English as a foreign or second language. This new third edition uses up-to-date examples to show differences and similarities between American and British english, reflecting a great deal of recent research in this area. It also takes account

    Full Text Available The perception and interpretation of the realia surrounding us is different among the representatives of different nations of the world. It manifests itself very clearly in phraseological units of the language as idioms accumulate the knowledge of the people and reflect culture, history, wisdom, beliefs, customs and traditions of the certain ethnic group. Comparative syntactic and grammatical analysis of phraseological units with the word воздух/air/l'air in the Russian, English and French languages represented in the article can reveal some aspects of the national mindset, linguistic and cultural peculiarities of the three nationalities.

    Romportl, Jan; Zackova, Eva; Beyond Artificial Intelligence : Contemplations, Expectations, Applications

    2013-01-01

    Products of modern artificial intelligence (AI) have mostly been formed by the views, opinions and goals of the “insiders”, i.e. people usually with engineering background who are driven by the force that can be metaphorically described as the pursuit of the craft of Hephaestus. However, since the present-day technology allows for tighter and tighter mergence of the “natural” everyday human life with machines of immense complexity, the responsible reaction of the scientific community should be based on cautious reflection of what really lies beyond AI, i.e. on the frontiers where the tumultuous ever-growing and ever-changing cloud of AI touches the rest of the world.   The chapters of this boo are based on the selected subset of the presentations that were delivered by their respective authors at the conference “Beyond AI: Interdisciplinary Aspects of Artificial Intelligence” held in Pilsen in December 2011.   From its very definition, the reflection of the phenomena that lie beyond AI must be i...

  20. The Return of Lombroso? Ethical Aspects of (Visions of) Preventive Forensic Screening.

    Munthe, Christian; Radovic, Susanna

    2015-11-01

    The vision of legendary criminologist Cesare Lombroso to use scientific theories of individual causes of crime as a basis for screening and prevention programmes targeting individuals at risk for future criminal behaviour has resurfaced, following advances in genetics, neuroscience and psychiatric epidemiology. This article analyses this idea and maps its ethical implications from a public health ethical standpoint. Twenty-seven variants of the new Lombrosian vision of forensic screening and prevention are distinguished, and some scientific and technical limitations are noted. Some lures, biases and structural factors, making the application of the Lombrosian idea likely in spite of weak evidence are pointed out and noted as a specific type of ethical aspect. Many classic and complex ethical challenges for health screening programmes are shown to apply to the identified variants and the choice between them, albeit with peculiar and often provoking variations. These variations are shown to actualize an underlying theoretical conundrum in need of further study, pertaining to the relationship between public health ethics and the ethics and values of criminal law policy.

    Full Text Available Subsidizing is the method that is argued by the followers of the free change. Anyway it is necessary as the means oforientation, adjustment and stimulation of some products and as the means of producers and consumers protection.The subsidies are given by the state in order to encourage those branches and sub-branches that are important forthe state's economy. The biggest part of the budget expenses for subsidizing is given to agriculture. The subsidiesare more oriented to agriculture because this branch is very important in the macroeconomic balance and inproviding food security. This research aims to show some aspects concerning the accounting of the subsidies givento agricultural entities taking into account the provisions presented in NAS "Equity and liabilities" and in NAS"Accounting peculiarities in agriculture". To achieve this aim we'll expose the accounting of the subsidies related tobiological fixed assets, the subsidies related to biological depreciable fixed assets. We will also examine thesituations in which the subsidizing conditions don't comply with the prescribed rules.

    The peculiarities of immunological reactivity in uterine and cervical cancer was studied. The study involved 94 patients who were administered combination radiation therapy for the above cancer. Before the treatment, the investigated group of the patients was characterized by the changes in a number of parameters of immunological reactivity (increased IgG, IgA, IgM serum concentrations, reduction of CD3+ and CD4+ amount, increased expression of CD95). The majority of changes were noticed immediately after the radiation therapy. Three and six month later the majority of immunological reactivity parameters did not differ from the respective values in the healthy group. Investigation of immunological reactivity in patients with uterine and cervical cancer allows to choose adequate treatment for this group of patients and improve its efficacy

    Full Text Available Este artigo tem como tema central o diabetes tipo 1 ou infanto-juvenil. Tendo em vista as repercussões que esta doença crônica traz, este trabalho levantou dados bibliográficos que subsidiassem reflexões sobre os aspectos emocionais vivenciados pelas crianças diabéticas. O resultado mostrou que o emocional influi na etiologia do diabetes e que o diabetes também influi no emocional desta criança. Isso ocorre devido aos cuidados incessantes para controle da doença, medo das possíveis complicações, mal-estar provocado pelos sintomas de hiper e hipoglicemia, o fato de ser "diferente". Sendo assim, é necessário um acompanhamento desta criança não só por médicos, mas também por outros profissionais da saúde, entre eles o psicólogo, objetivando elaboração dos aspectos referentes à doença e suas repercussões emocionais.This article has as its main point the type 1 or infantile-juvenile diabetes. Considering the repercussions that this chronic disease may cause, this study aims at performing a bibliographic survey with data that can give a subsidy to reflections on the emotional aspects experienced by the diabetic children. The findings showed that the emotional aspect influences the diabetes etiology and that the diabetes also influences the emotional aspect of this child. This is due to both the incessant cares used to control the disease and fear of possible complications, as well as to the indisposition caused by the hyper and hypoglycemia symptoms and the fact of being "different". Therefore, it is necessary an attendance of these children diabetes, not only by the doctors, but also by other health professionals, among them, the psychologist, aiming at the elaboration of the aspects related to the disease and its emotional repercussions.

  7. Nonlinear peculiar-velocity analysis and PCA

    Energy Technology Data Exchange (ETDEWEB)

    Dekel, A. [and others

    2001-02-20

    We allow for nonlinear effects in the likelihood analysis of peculiar velocities, and obtain {approximately}35%-lower values for the cosmological density parameter and for the amplitude of mass-density fluctuations. The power spectrum in the linear regime is assumed to be of the flat {Lambda}CDM model (h = 0:65, n = 1) with only {Omega}{sub m} free. Since the likelihood is driven by the nonlinear regime, we break the power spectrum at k{sub b} {approximately} 0.2 (h{sup {minus}1} Mpc){sup {minus}1} and fit a two-parameter power-law at k > k{sub b} . This allows for an unbiased fit in the linear regime. Tests using improved mock catalogs demonstrate a reduced bias and a better fit. We find for the Mark III and SFI data {Omega}{sub m} = 0.35 {+-} 0.09 with {sigma}{sub 8}{Omega}P{sub m}{sup 0.6} = 0.55 {+-} 0.10 (90% errors). When allowing deviations from {Lambda}CDM, we find an indication for a wiggle in the power spectrum in the form of an excess near k {approximately} 0.05 and a deficiency at k {approximately} 0.1 (h{sup {minus}1} Mpc){sup {minus}1}--a cold flow which may be related to a feature indicated from redshift surveys and the second peak in the CMB anisotropy. A {chi}{sup 2} test applied to principal modes demonstrates that the nonlinear procedure improves the goodness of fit. The Principal Component Analysis (PCA) helps identifying spatial features of the data and fine-tuning the theoretical and error models. We address the potential for optimal data compression using PCA.

    Peculiarities of heat transfer in crystallizator of semicontinuous blank casting machine were investigated, taking carbon and chromium-nickel steels as an example. The effect of crystallizator cross-section and decrease of the rate of metal casting on ingot cooling was considered at that. It was established that nonuniformity of deformation of ingot skin as well as the state of crystallizator operating walls affect on heat transfer in crystallizator. Crystallizator structure with ribs in upper part and without ribs in lower cone part is optimal. It provides more uniform skin growth in initial period of solidification and compensation of gap, which appears due to shrinkage

    Nematic liquid crystals in a polyhedral domain, a prototype for bistable displays, may be described by a unit-vector field subject to tangent boundary conditions. Here we consider the case of a rectangular prism. For configurations with reflection-symmetric topologies, we derive a new lower bound for the one-constant elastic energy. For certain topologies, called conformal and anticonformal, the lower bound agrees with a previous result. For the remaining topologies, called nonconformal, the new bound is an improvement. For nonconformal topologies we derive an upper bound, which differs from the lower bound by a factor depending only on the aspect ratios of the prism

    Numerous studies and clinical anecdotes reveal a relationship between attendance at A.A. meetings and/or degree of involvement in A.A. and maintenance of sobriety. Hypotheses as to how A.A. and/or the A.A. meeting is helpful to its members have ranged from a focus on factors common to all therapy groups, to aspects of A.A. "treatment" which are behavioral in nature. Presented here is another way of understanding A.A.'s effectiveness within the frame of more recent, constructivistic approaches to family therapy. In particular, the A.A. topic meeting is compared to the reflecting team concept of Tom Anderson.

  16. Consistencies far beyond chance: an analysis of learner preconceptions of reflective symmetry

    Directory of Open Access Journals (Sweden)

    Michael Kainose Mhlolo

    2013-01-01

    Full Text Available This article reports on regularities observed in learners' preconceptions of reflective symmetry. Literature suggests that the very existence of such regularities indicates a gap between what learners know and what they need to know. Such a gap inhibits further understanding and application, and hence needed to be investigated. A total of 235 Grade 11 learners, from 13 high schools that participate in the First Rand Foundation-funded Mathematics Education project in the Eastern Cape, responded to a task on reflective symmetry. Our framework for analysing the responses was based on the taxonomy of structure of the observed learning outcome. The results indicated that 85% of learner responses reflect a motion understanding of reflections, where learners considered geometric figures as physical motions on top of the plane. While this understanding is useful in some cases, it is not an essential aspect of mapping understanding, which is critical for application in function notations and other analytical geometry contexts. We suggest that if this gap is to be closed, learners need to construct these reflections physically so that they may think of reflections beyond motion.

  17. A reflective framework to foster emotionally intelligent leadership in nursing.

    2015-09-01

    To propose a reflective framework based on the perspective of emotional intelligence (EI) in nurse leadership literature. Emotional intelligence is a self-development construct aimed at enhancing the management of feelings and interpersonal relationships, which has become increasingly popular in nurse leadership. Reflection is an established means to foster learning. Integrating those aspects of emotional intelligence pertinent to nurse leadership into a reflective framework might support the development of nurse leadership in a practical context. A sample of 22 articles, retrieved via electronic databases (Ovid/Medline, BNI, psycArticles, Zetoc and CINAHL) and published between January 1996 and April 2009, was analysed in a qualitative descriptive content analysis. Three dimensions that characterise emotional intelligence leadership in the context of nursing - the nurse leader as a 'socio-cultural architect', as a 'responsive carer' and as a 'strategic visionary' - emerged from the analysis. To enable practical application, these dimensions were contextualised into a reflective framework. Emotional intelligence skills are regarded as essential for establishing empowering work environments in nursing. A reflective framework might aid the translation of emotional intelligence into a real-world context. The proposed framework may supplement learning about emotional intelligence skills and aid the integration of emotional intelligence in a clinical environment. © 2014 John Wiley & Sons Ltd.

    We present the first results from a targeted search for brown dwarfs with unusual red colors indicative of peculiar atmospheric characteristics. These include objects with low surface gravities or with unusual dust content or cloud properties. From a positional cross-match of SDSS, 2MASS, and WISE, we have identified 40 candidate peculiar early-L to early-T dwarfs that are either new objects or have not been identified as peculiar through prior spectroscopy. Using low-resolution spectra, we confirm that 10 of the candidates are either peculiar or potential L/T binaries. With a J − K{sub s} color of 2.62 ± 0.15 mag, one of the new objects—the L7 dwarf 2MASS J11193254–1137466—is among the reddest field dwarfs currently known. Its proper motion and photometric parallax indicate that it is a possible member of the TW Hydrae moving group. If confirmed, it would be the lowest-mass (5–6 M{sub Jup}) free-floating member. We also report a new T dwarf, 2MASS J22153705+2110554, that was previously overlooked in the SDSS footprint. These new discoveries demonstrate that despite the considerable scrutiny already devoted to the SDSS and 2MASS surveys, our exploration of these data sets is not yet complete.

    Full Text Available This article presents the empirical research carried out in the context of the multi-site EuroSDR project "Radiometric aspects of digital photogrammetric images" and provides highlights of the results. The investigations have considered the vicarious radiometric and spatial resolution validation and calibration of the sensor system, radiometric processing of the image blocks either by performing relative radiometric block equalization or into absolutely reflectance calibrated products, and finally aspects of practical applications on NDVI layer generation and tree species classification. The data sets were provided by Leica Geosystems ADS40 and Intergraph DMC and the participants represented stakeholders in National Mapping Authorities, software development and research. The investigations proved the stability and quality of evaluated imaging systems with respect to radiometry and optical system. The first new-generation methods for reflectance calibration and equalization of photogrammetric image block data provided promising accuracy and were also functional from the productivity and usability points of view. The reflectance calibration methods provided up to 5% accuracy without any ground reference. Application oriented results indicated that automatic interpretation methods will benefit from the optimal use of radiometrically accurate multi-view photogrammetric imagery.

    As a new curriculum reform program was put forward in China,higher standards for teachers were given that teachers must have a potential of reflective development.Continuing and effective professional development is a common concern of most teachers and professional educators.Effective professional development usually means that not only does it have immediate impact on the work of the professional educator,but it has a long lasting impact.Unfortunately,such effective professional development activities are rare and,in turn,costly to the organization.The purpose of this paper is to demonstrate a form of effective professional development which is not only economical but effective.That is the reflective journal.This article analyzes the application of Journal writing from these aspects of the definition,content and the procedures.

  13. A REVIEW: A MODEL of CULTURAL ASPECTS for SUSTAINABLE PRODUCT DESIGN

    2012-04-01

    Full Text Available Product design stages are important to consider critically in production. Generally, product design that shall be created by designer, should consider what the customer wants and needs. Nowadays issues, product design does not only consider the “wants and needs” of user, but also how the design can be created by embedding sustainability aspects in the product. Culture is also one of the important aspects which need to be considered in product design as culture affects the way users respond to the product. This paper aims to develop a new model for design development, in which the aspects of culture are incorporated into sustainable product design. By reviewing the existing literature, the authors attempt to identify the gaps of the existing papers, which illustrate how culture affects sustainable product design. Recent papers have only shown that culture influences product design, but they do not explore sustainability and the culture aspects in product design. Due to these gaps, it is therefore important to create a model which will assist designers to elicit sustainable product design based on cultural aspects. In summary, designers need to reflect on the “wants and needs” of users. The framework presented in this paper can be integrated into designers’ and companies’ decision-making during product design development.

    Ions coherently reflected off the Earth's bow shock have previously been observed both when the upstream geometry is quasi-perpendicular and when it is quasi-parallel. In the case of quasiperpendicular geometry, the ions are reflected in a nearly specular manner and are quickly carried back into the shock by the convecting magnetic field. In the quasi-parallel geometry, however, near-specularly reflected ions' guiding center velocities would on the average be directed away from the shock, allowing the ions to escape into the upstream region. The conditions under which coherent reflection occurs and the subsequent coupling of the reflected ions to the incoming solar wind plasma are important factors when assessing the contribution of the reflected ions to the downstream temperature increase and the shock structure. The survey presented in this paper, along with previously reported observations, suggests that near-specularly reflected ions are indeed an important aspect of energy dissipation at the Earth's quasi-parallel bow shock. The authors find that (1) cool, coherent, near-specularly reflected ion beams are detected over nearly the full range of upstream plasma paraameters commonly found at the Earth's bow shock; (2) the beams are typically observed only near the shock ramp or some shock-like feature; and (3) the observed beam velocities are almost always consistent with what one would expect for near-specularly reflected ions after only a small fraction of a gyroperiod following reflection. The second and third points indicate that the beams spread very quickly in velocity space. This spread in velocities could be due either to interactions between the beam and incoming solar wind ions or to some initially small velocity spread in the beam

    Adapting university programmes to European Higher Education Area criteria has required substantial changes in curricula and teaching methodologies. Reflective learning (RL) has attracted growing interest and occupies an important place in the scientific literature on theoretical and methodological aspects of university instruction. However, fewer studies have focused on evaluating the RL methodology from the point of view of nursing students. To assess nursing students' perceptions of the usefulness and challenges of RL methodology. Mixed method design, using a cross-sectional questionnaire and focus group discussion. The research was conducted via self-reported reflective learning questionnaire complemented by focus group discussion. Students provided a positive overall evaluation of RL, highlighting the method's capacity to help them better understand themselves, engage in self-reflection about the learning process, optimize their strengths and discover additional training needs, along with searching for continuous improvement. Nonetheless, RL does not help them as much to plan their learning or identify areas of weakness or needed improvement in knowledge, skills and attitudes. Among the difficulties or challenges, students reported low motivation and lack of familiarity with this type of learning, along with concerns about the privacy of their reflective journals and about the grading criteria. In general, students evaluated RL positively. The results suggest areas of needed improvement related to unfamiliarity with the methodology, ethical aspects of developing a reflective journal and the need for clear evaluation criteria.

    In this paper, we qualitatively analyzed peculiarities of laser phase behavior associated with the accelerated electron in a chirped laser pulse. We unveiled the relationship between the changes in the orientation of the electron trajectory and the cusps in magnitude of the phase velocity of the optical field along the electron trajectory in a chirped laser pulse. We also explained how the chirp effect induced the singular point of the phase velocity. Finally, we discussed the phase velocity and phase witnessed by the electron in the particle's moving instantaneous frame

    2002-01-01

    We investigate the impact of peculiar velocity effects due to the motion of the solar system relative to the cosmic microwave background (CMB) on high resolution CMB experiments. It is well known that on the largest angular scales the combined effects of Doppler shifts and aberration are important; the lowest Legendre multipoles of total intensity receive power from the large CMB monopole in transforming from the CMB frame. On small angular scales aberration dominates and is shown here to lead to significant distortions of the total intensity and polarization multipoles in transforming from the rest frame of the CMB to the frame of the solar system. We provide convenient analytic results for the distortions as series expansions in the relative velocity of the two frames, but at the highest resolutions a numerical quadrature is required. Although many of the high resolution multipoles themselves are severely distorted by the frame transformations, we show that their statistical properties distort by only an insignificant amount. Therefore, the cosmological parameter estimation is insensitive to the transformation from the CMB frame (where theoretical predictions are calculated) to the rest frame of the experiment

    2016-01-01

    Full Text Available This paper sets out to establish a comparative study between classes of spin- and velocity-dependent potentials for spin-1/2 and spin-1 matter currents/sources in the nonrelativistic regime. Both (neutral massive scalar and vector particles are considered to mediate the interactions between (pseudo-scalar sources or (pseudo-vector currents. Though our discussion is more general, we contemplate specific cases in which our results may describe the electromagnetic interaction with a massive (Proca-type photon exchanged between two spin-1/2 or two spin-1 carriers. We highlight the similarities and peculiarities of the potentials for the two different types of charged matter and also focus our attention on the comparison between the particular aspects of two different field representations for spin-1 matter particles. We believe that our results may contribute to a further discussion of the relation between charge, spin, and extensibility of elementary particles.

    Imaging of seismic reflection data is usually based on the assumption that the seismic response consists of primary reflections only. Multiple reflections, i.e. waves that have reflected more than once, are treated as primaries and are imaged at wrong positions. There are two classes of multiple reflections, which we will call surface-related multiples and internal multiples. Surface-related multiples are those multiples that contain at least one reflection at the earth's surface, whereas internal multiples consist of waves that have reflected only at subsurface interfaces. Surface-related multiples are the strongest, but also relatively easy to deal with because the reflecting boundary (the earth's surface) is known. Internal multiples constitute a much more difficult problem for seismic imaging, because the positions and properties of the reflecting interfaces are not known. We are developing reflection imaging methodology which deals with internal multiples. Starting with the Marchenko equation for 1D inverse scattering problems, we derived 3D Marchenko-type equations, which relate reflection data at the surface to Green's functions between virtual sources anywhere in the subsurface and receivers at the surface. Based on these equations, we derived an iterative scheme by which these Green's functions can be retrieved from the reflection data at the surface. This iterative scheme requires an estimate of the direct wave of the Green's functions in a background medium. Note that this is precisely the same information that is also required by standard reflection imaging schemes. However, unlike in standard imaging, our iterative Marchenko scheme retrieves the multiple reflections of the Green's functions from the reflection data at the surface. For this, no knowledge of the positions and properties of the reflecting interfaces is required. Once the full Green's functions are retrieved, reflection imaging can be carried out by which the primaries and multiples are

    Early-type galaxies (ETGs) are very important for understanding the formation and evolution of galaxies. Recent observations suggest that ETGs are not simply old stellar spheroids as we previously thought. Widespread recent star formation, cool gas and dust have been detected in a substantial fraction of ETGs. We make use of the radial profiles of g — r color and the concentration index from the Sloan Digital Sky Survey database to pick out 31 peculiar ETGs with central blue cores. By analyzing the photometric and spectroscopic data, we suggest that the blue cores are caused by star formation activities rather than the central weak active galactic nucleus. From the results of stellar population synthesis, we find that the stellar population of the blue cores is relatively young, spreading from several Myr to less than one Gyr. In 14 galaxies with H I observations, we find that the average gas fraction of these galaxies is about 0.55. The bluer galaxies show a higher gas fraction, and the total star formation rate (SFR) correlates very well with the H I gas mass. The star formation history of these ETGs is affected by the environment, e.g. in the denser environment the H I gas is less and the total SFR is lower. We also discuss the origin of the central star formation of these early-type galaxies.

    The purpose of this research was to explore the value of reflection and its application to practice through the implementation of educational modules within a new Diabetes Care and Education Master Degree Programme in Kuwait, and to realise how this teaching intervention informs changes in practice. A small exploratory case study was conducted within the Dasman Diabetes Institute, Kuwait. A qualitative approach using focus group interviews was carried out with seventeen participants all of whom are studying on the Diabetes Care and Education Master Degree Programme in Kuwait. An inductive approach to thematic analysis, which focused on examining themes within data, was performed. The results indicate that participants value the opportunity to study through organised, structured and assessed reflection. The learning provides useful information and support to the participant by highlighting the role which reflection plays to enhance personal and professional development, the value of educational theory, continuing professional development, collaboration and enhancing patient education and practice. The significance of reflection is often seen in the literature as an important aspect of professional competence. This research has highlighted the value of reflection as a key component within a new educational programme.

    The purpose of this article is to analyze some models of expert decision and their impact on the clinical practice. We have analyzed decision-making considering the cognitive aspects (explanatory models, perceptual skills, analysis of the variability of a phenomenon, creating habits and inertia of reasoning and declarative models based on criteria). We have added the importance of emotions in decision making within highly complex situations, such as those occurring within the clinical practice. The quality of the reflective act depends, among other factors, on the ability of metacognition (thinking about what we think). Finally, we propose an educational strategy based on having a task supervisor and rectification scenarios to improve the quality of medical decision making. Copyright © 2013 Elsevier España, S.L.

    The effects of multiple internal reflections within a laser weld joint as a function of joint geometry and processing conditions have been characterized. A computer model utilizing optical ray tracing is used to predict the reflective propagation of laser beam energy focused into the narrow gap of a metal joint for the purpose of predicting the location of melting and coalescence which form the weld. The model allows quantitative analysis of the effects of changes to joint geometry, laser design, materials and processing variables. This analysis method is proposed as a way to enhance process efficiency and design laser welds which display deep penetration and high depth to width aspect ratios, reduced occurrence of defects and enhanced melting. Of particular interest to laser welding is the enhancement of energy coupling to highly reflective materials. The weld joint is designed to act as an optical element which propagates and concentrates the laser energy deep within the joint to be welded. Experimentation has shown that it is possible to produce welds using multiple passes to achieve deep penetration and high depth to width aspect ratios without the use of filler material. The enhanced laser melting and welding of aluminum has been demonstrated. Optimization through modeling and experimental validation has resulted in the development of a laser welding process variant we refer to as Ultra-Narrow Gap Laser Welding.

    Full Text Available The epilepsy treatment is to be based on existing general principles and standards of therapy with differential approach to each patient. Besides peculiarities of treatment of different types of seizures and forms of epilepsy there are also differential approaches to special groups of patients. To one of such groups are referred to women of reproductive age. These patients are referred to special group of risk due to the development of certain side effects of antiepileptic drugs (АED. This article focuses in details on peculiarities of treatment of women of reproductive age with epilepsy with accent made on tolerability and safety of the antiepileptic therapy. It is necessary to take into consideration, that at women neuroendocrinal disorders can be caused both by the disease itself – epilepsy (in such case disorders depend on the starting age, form of epilepsy, focal localization, duration of disorder and other factors, referred to the disease, as well as by the undertaken therapy. The articlehereunder considers only issues, referred to the treatment, i. e. AED side effects and its input in the decrease of life quality of women with epilepsy. As women’s reproductive function starts forming long ago before childbearing age, it is necessary for this category to comprise not only women and adolescents, but girls as well. Notwithstanding the fact that so called benign forms of epilepsy pass before the pubescence period (idiopathic focal epilepsies, several forms of idiopathic generalized epilepsy, in many cases the epilepsy, which has started in childhood, continues in the adult age as well. In the same time there can be possible remote negative consequences of the antiepileptic therapy, which can show at a woman of a reproductive age. The data, given in the article, witnesses the need of the right AED selection at women of reproductive age, suffering from epilepsy. The AED should be selected not only depending on the form of the

    Full Text Available This paper aims to describe some aspects of the Afro-American culture in Colombia starting from the observation of its religious manifestations. The ethnographic analysis of the activities carried out within the framework of the Afro-Colombian Catholic pastoral care allows us to reflect on the importance of the notions of identity, corporeality and spirituality for the descendants of former African slaves in Colombia. From an anthropological point of view, the Afro-Colombian pastoral can be analyzed as a peculiar form of religious syncretism which demonstrates the resilience of African descendants faced with the pressure of the enculturation process led by the Catholic Church.

    The author highlights the importance of emotions in all ethical reflections. He describes the most common positions of ethicists employing duties and rights as the basis for ethical thought. The author, goes to Freudian theory as viewed by the utilitarians, stating that the 'quest for pleasure' is not necessarily egocentric, especially for adults. For example, the feeling of solidarity emerges 'from the inside out', making irrelevant all the emphasis laid on obedience to duty (from the outside in). The article questions the essence of Kantian theory, based exclusively on 'reason' with disregard for feelings, by establishing what he considers a 'positivist' view of rational thought. It emphasizes the principle of autonomy, which it seen as basically opposing the principles of beneficence and fairness. It is proposed that the latter should be seen as what he calls heteronomy (a concept different from that of the rational ethicists). In theory, autonomy is not assigned to anyone on the basis of an external assessment. Any intervention in individual autonomy must be made (by the intervenor) when it becomes imperative in the defense of social or cultural values. The article distinguishes between ethics and morals) and states that the sole acceptable ethical principle is that ethics (theoretically) has no principle.

    It is known that the aging of the world population during the twentieth century and the beginning of this new century is a first-order challenge for nations, especially in the socio-economic field. An important aspect of the aging of global population is that, for older age groups, the prevalence of degenerative diseases is also higher, including malignancies. On the other hand, among the population of patients with cancer, half of these patients will receive radiation therapy at some point in their illness and their individual characteristics can somehow influence the prognosis, the indication and daily doses of treatment prescriptions. In this context, the health assistance for the elderly patient with cancer should be seen as an important challenge, mainly due to two factors: an increased demand for treatments, in quantitative terms, and physiological characteristics unique to this population, which can influence the therapeutic decision-making. This review proposes a discussion of some relevant aspects of both the physiology of the elderly, which may influence the course of radiation therapy, as well as of some technical advances in radiotherapy, which can in turn benefit these patients by offering, for example, lower toxicity, greater effectiveness and speed.

    We ask which are the clinically relevant qualities of narratives in psychotherapy and how they can be measured. On the background of psychoanalytic assumptions and narrative theory, we propose to measure formal narrative processes which stay close to the linguistic surface, because these escape conscious control. We propose five aspects of narratives to be especially sensitive to distortions and therefore prone to change in successful therapies: (1) The actual chronological, stepwise narrating of events, (2) the intentional structuring of events, or emplotment, (3) the immediate evaluation, (4) the reflected interpretation of events, and finally (5) the consistency and completeness of the narrative. For each aspect we discuss ways to measure them. Finally the aspects are illustrated with excerpts from a series of diagnostic interviews. Implications for the analysis of the co-narrative role of the therapist are suggested.

    Full Text Available Leukocyte telomere length and serum levels of high-molecular-weight adiponectin and dehydroepiandrosterone-sulfate (DHEA-S were assessed in association with nutrition and performance status (PS in Japanese centenarians. Twenty-three centenarians (five men, 18 women were classified according to their PS 1 (nearly fully ambulatory, n = 2, 2 (in bed less than 50% of daytime, n = 10, 3 (in bed greater than 50%, n = 6, and 4 (completely bedridden, n = 5. Leukocyte telomere length was determined by the hybridization protection assay, and the adiponectin and DHEA-S levels were measured by chemiluminescent enzyme immunoassay. Among variables of PS, body mass index (BMI, albumin, adiponectin, DHEA-S, and telomere length, there were significant correlations between PS and albumin ( r = −.694, p < .01, between telomere length and BMI ( r = .522, p < .05, between adiponectin and BMI ( r = −.574, p < .01, and between DHEA-S and albumin ( r = .530, p < .01. When excluding two cancer-bearing centenarians with short telomere, telomere length significantly correlated with PS ( r = −.632, p < .01. It was indicated that the short leukocyte telomere was associated with poor PS and cancer development and that the adiponectin or DHEA-S was associated with adiposity or nutritional status. Despite a small number of subjects, these biomarkers seemed to reflect distinct aspects of longevity in Japanese centenarians.

    2003-04-01

    We carried out polarimetric spectral-line imaging of the molecular outflow of the peculiar red supergiant VY Canis Majoris in SiO J=1-0 line in the ground vibrational state, which contains highly linearly-polarized velocity components, using the Very Large Array. We succeeded in unveiling the highly linearly polarized bipolar outflow for the first time at subarcsecond spatial resolution. The results clearly show that the direction of linear polarization of the brightest maser components is parallel to the outflow axis. The results strongly suggest that the linear polarization of the SiO maser is closely related to the outflow phenomena of the star. Furthermore, the results indicate that the linear polarization observed in the optical and infrared also occur due to the outflow phenomena.

  8. Aspect-related Vegetation Differences Amplify Soil Moisture Variability in Semiarid Landscapes

    2017-12-01

    Soil moisture variability (SMV) in semiarid landscapes is affected by vegetation, soil texture, climate, aspect, and topography. The heterogeneity in vegetation cover that results from the effects of microclimate, terrain attributes (slope gradient, aspect, drainage area etc.), soil properties, and spatial variability in precipitation have been reported to act as the dominant factors modulating SMV in semiarid ecosystems. However, the role of hillslope aspect in SMV, though reported in many field studies, has not received the same degree of attention probably due to the lack of extensive large datasets. Numerical simulations can then be used to elucidate the contribution of aspect-driven vegetation patterns to this variability. In this work, we perform a sensitivity analysis to study on variables driving SMV using the CHILD landscape evolution model equipped with a spatially-distributed solar-radiation component that couples vegetation dynamics and surface hydrology. To explore how aspect-driven vegetation heterogeneity contributes to the SMV, CHILD was run using a range of parameters selected to reflect different scenarios (from uniform to heterogeneous vegetation cover). Throughout the simulations, the spatial distribution of soil moisture and vegetation cover are computed to estimate the corresponding coefficients of variation. Under the uniform spatial precipitation forcing and uniform soil properties, the factors affecting the spatial distribution of solar insolation are found to play a key role in the SMV through the emergence of aspect-driven vegetation patterns. Hence, factors such as catchment gradient, aspect, and latitude, define water stress and vegetation growth, and in turn affect the available soil moisture content. Interestingly, changes in soil properties (porosity, root depth, and pore-size distribution) over the domain are not as effective as the other factors. These findings show that the factors associated to aspect-related vegetation

    Investigation of transuranian elements 239Pu, 240Pu, 241Am, as well as 137Cs and 90Sr after Chernobyl accident release adsorption and accumulation by the macrophytes of water systems in Gomel region of the Republic of Belarus was realized. Noted biological diversity in accumulation of radionuclides by the terrain flora was also typical for the higher aquatic plants. Research results showed that the degree of accumulation depended on the morphophysiological peculiarities of each plant body. Various indices of radionuclide accumulation coefficient for each analysed transuranian element were stated in one and the same aquatic media with the equal physical and chemical properties. Accumulation of transuranian elements by macrophytes was determined by the peculiar properties of radionuclides as chemical elements and by the forms of their existence in the aqueous media. In one and the same analysed plant of the certain water system the accumulation coefficients of different radionuclides differed. Similarity in concentrations of different radionuclides in all studied water systems was analysed. Research results showed that accumulation indices of comparatively easity determined 137Cs could help to determine the relative concentration of other radionuclides which could be analyzed with more difficulties (90 Sr, and especially 239Pu, 240Pu, 241Am)

    2015-01-01

    Gender differences, in both clinical and research environment, exist also in a particular category of patients, adolescents, who constitute a vulnerable group with respect to healthcare decisions. In clinical context, the main ethical issues that may be identified within gender medicine for adolescent patients are related to the information given to the patient and its parents, the adolescent's capacity of understanding considering his/her maturity, vulnerability and autonomy, the consent to medical treatment in relation to the different possible approaches to their different efficacy and possible side effects. Also, with regard to the research context, ethical issues may arise from the participation of female minors in clinical trials. Ethical concerns may also arise in the field of resource allocation in health policies, such as the equitable distribution and access to resources, considering the young age of the subjects involved. A bioethical reflection, which takes into account not only the differences biologically and epidemiologically relevant, but also the main determinants of health in adolescence, might find a role in structured education for diversity and gender equity. Given the magnitude of the problem, to encourage the pursuit of gender equity in health and, in some situations, also to promote the full recognition of the right to health of women are some of the most effective and direct ways to reduce inequalities and to ensure a rational and efficient use of available resources, including through a bioethical reflection on the topic. The Authors show the necessity to differentiate the various aspects of gender differences in adolescence medicine, providing arguments in support of the fact that interventions for health prevention and promotion should be modulated in relation to the gender of the recipients, emphasizing the most important aspects for each group of individuals. This approach could implement personalized medicine, even and especially

    Celosterna pollinosa sulfurea and Phosphorus virescens are longhorn beetles which both have a sulphur-yellow pigmentary coloration and, more surprisingly, a yellow-green fluorescence coloration. In this study, we used a refined experimental examination to characterize the angular distribution of light and unveiled a different behavior between these reflection and emission processes. A key feature of these observations is the peculiar architecture of the scales (a three-dimensional photonic structure), which acts differently on each phenomenon. For reflection, this architecture can be viewed as a scattering device, while, for emission, it can be viewed as a waveguide. These effects were investigated by scanning electron microscopy (SEM), Bidirectional Reflectance Distribution Function (BRDF) diagrams and spectrophotometric measurements. Collection and analysis of data at every emergence direction was found to be crucial when studying optical properties in materials with spatial changes in composition at the scale of the light wavelength. -- Highlights: ► We examine structurally modified fluorescence in two longhorn beetles. ► Reflection and emission are complementary processes in the final visual aspect. ► The specific three-dimensional photonic structure of the scales is the keystone. ► Structure impacts the spatial angular distribution of reflected and emitted light.

    Peculiarities of fusible metal alloys interaction with ammonium halogenides in vertical reactor are considered using indium-tin and indium-bismuth binary alloys. It is shown that at the end of the process the composition of metal and salt phases is determined by the equilibrium type and constant characteristic of the given salt-metal system. As a result the interaction of indium-tin and indium-bismuth alloys with ammonium halogenides leads to preferential halogenation of indium-bismuth alloys with ammonium halogenides leads to preferential halogenation of indium which may be used in the processes of separation or purification. A model is suggested to calculate the final concentration of salt and metal phase components

    Full Text Available Background: At the South Eastern Sydney Local Health District Nursing and Midwifery Practice and Workforce Unit, we use the framework of CARE (a compound acronym of Capacity, cApability, collaboRation and culturE to inform all aspects of work. The principles of practice development (Manley et al., 2008 also inform our work, a major focus of which is the use of coaching, action learning sets and active learning techniques. The use of questions and questioning is key to these. These techniques are part of our person-centred approach to professional development and learning. This article describes my reflections, using Gibbs’ model (1988, on the development of a questioning tool aimed at enhancing learning through play. The tool is an origami ‘chatterbox’, which was originally developed as part of a ‘poster’ presentation at the 2014 International Practice Development Conference in Toronto. Aims and objectives: This article aims to share a critical reflection on developing and using the chatterbox and to describe how this experience led to deeper reflections on the role of play in adult learning. Conclusions and implications for practice: The chatterbox has provided a simple and effective tool for introducing, practising and reinforcing the use of enabling questions. Its development allowed the categorisation of enabling questions. Personal reflections undertaken as part of the development of the tool inspired me to explore the literature about the role of play in adult learning. It has implications for supporting the learning of people who are interested in using enabling questions, by increasing their skill and confidence.

    Childhood cancer care involves many ethical concerns. Deciding on treatment levels and providing care that infringes on the child's growing autonomy are known ethical concerns that involve the whole professional team around the child's care. The purpose of this study was to explore healthcare professionals' experiences of participating in ethics case reflection sessions in childhood cancer care. Data collection by observations, individual interviews, and individual encounters. Data analysis were conducted following grounded theory methodology. Healthcare professionals working at a publicly funded children's hospital in Sweden participated in ethics case reflection sessions in which ethical issues concerning clinical cases were reflected on. The children's and their parents' integrity was preserved through measures taken to protect patient identity during ethics case reflection sessions. The study was approved by a regional ethical review board. Consolidating care by clarifying perspectives emerged. Consolidating care entails striving for common care goals and creating a shared view of care and the ethical concern in the specific case. The inter-professional perspectives on the ethical aspects of care are clarified by the participants' articulated views on the case. Different approaches for deliberating ethics are used during the sessions including raising values and making sense, leading to unifying interactions. The findings indicate that ethical concerns could be eased by implementing ethics case reflection sessions. Conflicting perspectives can be turned into unifying interactions in the healthcare professional team with the common aim to achieve good pediatric care. Ethics case reflection sessions is valuable as it permits the discussion of values in healthcare-related issues in childhood cancer care. Clarifying perspectives, on the ethical concerns, enables healthcare professionals to reflect on the most reasonable and ethically defensible care for the child

    Full Text Available The article provides results of the research on eating behavior and diet peculiarities of students belonging to various age groups, who studied at secondary schools in the villages and district centers of Lviv Region. It was found that students of different age groups (grades have certain eating behavior peculiarities, though none of them corresponds to the model of balanced nutrition. In particular, students of 1-4 grades mainly consumed specially cooked food 4-5 times a day at home, did not always eat their entire serve, and often had snacks in between the main meals, eating vegetables/fruits, and bakery. Their behavior during food intake is agitated and unfocused. Eating behavior of secondary school students had the following peculiarities: the majority of students ate 3 times a day and were likely to ignore breakfasts, consumed food cooked for the whole family and did at home, did not always eat all of the offered serve. Instead, at schools they had frequent snacks consisting of vegetables/fruit, bakery, and sweets. With regard to seniors, their eating behavior had its own peculiarities. They were primarily related to active physiologic increase in body growth and weight, the need to spend the whole academic day at school, spend more time on homework, as well as help parents around the house. This research group had 9.7% of persons who had an adequate meal 6 times a day. However, the diet was unbalanced, since most meals where consumed in the afternoon, as well as during evening and night hours. We should also note, that students of 9-11 grades more often than other age groups in the research, ate at school canteens and public catering establishments, ate all of the food offered to them, were calm and attentive during food intake and had the largest number of snacks in between the main meals. What concerns their diet, it did not correspond to the characteristics of the balanced one, when it comes to consuming products required for the

    Context. The Milky Way (MW) and Andromeda (M 31) galaxies possess rotating planes of satellites. The formation of these planes has not been explained satisfactorily so far. It has been suggested that the MW and M 31 satellites are ancient tidal dwarf galaxies; this might explain their configuration. This suggestion gained support by an analytic backward-calculation of the relative MW-M 31 orbit in the MOND modified dynamics paradigm. The result implied that the galaxies experienced a close flyby 7-11 Gyr ago. Aims: Here we explore the Local Group history in MOND in more detail using a simplified first-ever self-consistent simulation. We describe the features induced by the encounter in the simulation and identify possible real counterparts of these features. Methods: The initial conditions were set to eventually roughly reproduce the observed MW and M 31 masses, effective radii, separation, relative velocity, and disk inclinations. We used the publicly available adaptive-mesh-refinement code Phantom of RAMSES. Results: Matter was transferred from the MW to M 31 along a tidal tail in the simulation. The encounter induced the formation of several structures resembling the peculiarities of the Local Group. Most notably are that 1) a rotating planar structure formed around M 31 from the transferred material. It had a size similar to the observed satellite plane and was oriented edge-on to the simulated MW, just as the real plane. 2) The same structure also resembled the tidal features observed around M 31 by its size and morphology. 3) A warp in the MW developed with an amplitude and orientation similar to that observed. 4) A cloud of particles formed around the simulated MW, with the extent of the actual MW satellite system. The encounter did not end by merging in a Hubble time. The simulated stellar disks also thickened as a result of the encounter. Conclusions: The simulation demonstrated that MOND might explain many peculiarities of the Local Group; this needs to

    Full Text Available Malaysia’s various ethnic groups make interesting study both sociologically and culturally. With such a heady mix of cultural elements to explore, it is often natural that the many groups stumble upon ‘rare gems’ that reflect their ‘Malaysianess’. Have Malaysians really ever appreciated the many and varied aspects of culture that they are seemingly suddenly thrown into? Do we embrace these happily or are we constantly rejecting them? Fortunately, through the medium of film, we are, from time to time, allowed to reflect on our obvious similarities and even more apparent disparities. In this paper, we explore the culture and perceptions of people from the major ethnic groups that are the human base of this very country. When was it we have last laughed at ourselves … heartily? Nasi Lemak 2.0 provides an interesting, if not disturbing insight into the workings of the Malaysian ‘mind’. Nasi Lemak 2.0 was released on 8th September 2011 and impacted a whole generation of Malaysians. The characters have been well chosen and have done a wonderful job of being representations of the various communities in this nation. Ethnocentrism is a reality and often rears its head, ‘ugly’ or otherwise in several situations. Are we able to grapple with the levels of ethnocentrism that we encounter? These are some of the issues that will trigger much debate and discussion among ourselves and perhaps also reflect our cores.

    Bistable color cholesteric liquid crystal displays are unique LCDs that exhibit high reflectivity, good contrast, extremely low power operation, and are amenable to versatile roll-to-roll manufacturing. The display technology, now branded as Reflex has been in commercialized products since 1996. It has been the subject of extensive research and development globally by a variety of parties in both academic and industrial settings. Today, the display technology is in volume production for applications such as dedicated eWriters (Boogie Board), full color electronic skins (eSkin), and displays for smart cards. The flexibility comes from polymerization induced phase separation using unique materials unparalleled in any other display technology. The blend of monomers, polymers, cross linkers, and other components along with nematic liquid crystals and chiral dopants is created and processed in such ways so as to enable highly efficient manufactrable displays using ultra thin plastic substrates -- often as thin as 50μm. Other significant aspects include full color by stacking or spatial separation, night vision capability, ultra high resolution, as well as active matrix capabilities. Of particular note is the stacking approach of Reflex based displays to show full color. This approach for reflective color displays is unique to this technology. Owing to high transparency in wavelength bands outside the selective reflection band, three primarily color layers can be stacked on top of each other and reflect without interfering with other layers. This highly surprising architecture enables the highest reflectivity of any other reflective electronic color display technology. The optics, architecture, electro-topics, and process techniques will be discussed. This presentation will focus on the physics of the core technology and color, it's evolution from rigid glass based displays to flexible displays, development of products from the paradigm shifting concepts to consumer

    Full Text Available Neither the gender aspects of racial discrimination nor the racial aspects of gender discrimination are fully comprehended within human rights discourses. Building on the growing recognition that race and gender discrimination are not mutually exclusive phenomena, this background paper forwards a provisional framework to identify various forms of subordination that can be said to reflect the interactive effects of race and gender discrimination. It suggests a provisional protocol to be followed to better identify the occasions in which such interactive discrimination may have occurred, and posits further that the responsibility to address the causes and consequences of such discrimination be shared widely among all human rights institutions.

  15. Does formal complexity reflect cognitive complexity? Investigating aspects of the Chomsky Hierarchy in an artificial language learning study.

    Öttl, Birgit; Jäger, Gerhard; Kaup, Barbara

    2015-01-01

    This study investigated whether formal complexity, as described by the Chomsky Hierarchy, corresponds to cognitive complexity during language learning. According to the Chomsky Hierarchy, nested dependencies (context-free) are less complex than cross-serial dependencies (mildly context-sensitive). In two artificial grammar learning (AGL) experiments participants were presented with a language containing either nested or cross-serial dependencies. A learning effect for both types of dependencies could be observed, but no difference between dependency types emerged. These behavioral findings do not seem to reflect complexity differences as described in the Chomsky Hierarchy. This study extends previous findings in demonstrating learning effects for nested and cross-serial dependencies with more natural stimulus materials in a classical AGL paradigm after only one hour of exposure. The current findings can be taken as a starting point for further exploring the degree to which the Chomsky Hierarchy reflects cognitive processes.

    Conditions that facilitate high Ps formation and interactions that modify the o-Ps lifetime were investigated by positron annihilation techniques in silicalite-1 and various Y-zeolites. Long lifetimes, up to 135 ns, and o-Ps fractions as high as 40% were found. The influence of heat treatment (in the range of 90-520 K), capillary condensation of N sub 2 (0.085 MPa) and correlation with water removal was examined in Y-zeolites and in silicalite-1, respectively. The latter matrix was also studied in the presence of liquids. In various samples unexpected features were found (peculiar changes in the 2 gamma/3 gamma ratio, inversion in the trend of lifetime variations, disappearance of specific components, etc.), denoting the complexity of the processes governing the fate of e sup sup + and Ps.

  20. Food for thought: Conditions for discourse reflection in the light of environmental assessment

    2010-01-01

    People tend to take notice of what is happening around them selectively. Discourses-frames through which actors give meaning to aspects of the world-act as built-in filters that distinguish relevant from irrelevant data. Use of knowledge generated by environmental assessments (EAs) in decision-making may be understood from this perspective. Environmental knowledge that is inconsistent with dominant discourses runs the risk of being ignored. Discourses on the value of EA as a tool for decision-making may have a similar effect. Stimulating decision-makers and stakeholders to critically reflect on and reconsider their discourses in the light of EAs-also known as frame reflection or policy learning-may enhance the probability that these assessments and the knowledge that they generate impact upon decision-making. Up to now little has been written about how discourse reflection in the context of EA can be promoted. Valuable inputs are fragmented over different bodies of literature. In this paper we draw from these bodies to identify favourable conditions for discourse reflection.

    2017-07-01

    Full Text Available The Feature for this issue Reflections on Student Persistence has been prepared by Professor Vincent Tinto, Distinguished University Professor Emeritus at Syracuse University, United States of America (USA and a longtime friend and supporter of STARS. Vincent explores the case for motivation to be considered as a significant aspect of the tertiary student psyche by drawing on theoretical frameworks, research and practical experiences related to the issue. He synthesises this extensive, detailed, rich but often somewhat impenetrable data into a trilogy of clear and credible key dimensions of the motivation construct student self efficacy, sense of belonging and perceived value of the curriculum. This interpretation of the literature is a personal but informed reflection and is a timely piece which highlights the breadth and profundity of the presentations at this year's conference in Adelaide, Australia where students in all their diversity are central to our focus on enhancing the student experience. In this opening article, Vincent refers directly to the STARS papers selected for this Conference issue of the Journal which also address the importance of student persistence, self-efficacy and building the sense of belonging within their own institutional communities (Fernandes, Ford, Rayner & Pretorius; Kahu, Nelson, & Picton; McFarlane, Spes-Skrbis & Taib; Naylor; Smallhorn. Echoing his position on social justice and his advocacy for underserved students, Vincent reminds us that educational equity gaps still exist, and he encourages us to see the issue of persistence through the eyes of the students to support their perseverance and completion and thereby help reduce educational disadvantage.

  2. Peculiarities in the demand forecast for an HSRL connecting two countries. Case of Kuala Lumpur Singapore HSRL

    The High Speed Rail Line (HSRL) between Kuala Lumpur (KL) and Singapore (SP) is aimed at reducing to 90 minutes the travel time between two of Southeast Asia’s most vibrant and fast-growing economic engines. Ineco was hired by the Government of Malaysia to forecast the demand for the future HSRL. The Government of Malaysia played a key role when firstly defining the current situation on the corridor and the features of the HSRL, and then providing Ineco with the studies previously developed by them. Besides the obvious interest in connecting both capital cities, Malaysia wishes to promote the economic development of intermediate cities, whereas Singapore, a 718 square-kilometer city-state and island, is interested in improving its connection with Nusajaya - a Malaysian city that is being developed just across the border and regarded as land reserves. Two kinds of services will be provided on the new rail infrastructure: non-stop services between KL and SP, and services with 6 intermediate stops on the Malaysian side. The aim of this paper is to describe the process to forecast the demand for the HSRL Kuala Lumpur – Singapore by focusing on the peculiarities of an international HSRL. Identifying these aspects at an early stage is vital to get a better demand estimate and to reconsider the HSRL characteristics if necessary. The demand for the new line was calculated by applying a three-step model: generation model, distribution model and modal split model. In 2030, 10 years after the opening year, the HSRL is expected to move 23 - 26 million passengers – baseline and optimistic scenarios, respectively -, which represents an 18.5% share of the total demand on the corridor. The demand for the KL-SP pair will account for 30% the demand for the future HSRL. (Author)

    This article is a reflection on how interculturality, understood as the way to improve the health of the Bolivian population and coupled with the concept of living well, is not contributing to improving the quality of life and health of the most vulnerable populations in the country. The discourse is coupled with the intention of saving lives in its broadest sense; however, for this it is necessary to make decisions about environmental health and extractivist policies that are not taken into account in the health issues affecting indigenous communities, a population targeted by the intercultural aspects of the health reform.

    The article describes the infl uence of the Bible geographic object peculiarities on the spatiotemporal geoinformation system of the Bible events. In the proposed concept of this system the special attention was concentrated to the Bible geographic objects and interrelations between the names of these objects and their location in the geospace. In the Bible, both in the Old and New Testament, there are hundreds of geographical names, but the selection of these names from the Bible text is not so easy. The same names are applied for the persons and geographic objects. The next problem which arises is the classification of the geographical object, because in several cases the same name is used for the towns, mountains, hills, valleys etc. Also very serious problem is related to the time-changes of the names. The interrelation between the object name and its location is also complicated. The geographic object of this same name is located in various places which should be properly correlated with the Bible text. Above mentioned peculiarities of Bible geographic objects infl uenced the concept of the proposed system which consists of three databases: reference, geographic object, and subject/thematic. The crucial component of this system is proper architecture of the geographic object database. In the paper very detailed description of this database is presented. The interrelation between the databases allows to the Bible readers to connect the Bible text with the geography of the terrain on which the Bible events occurred and additionally to have access to the other geographical and historical information related to the geographic objects.

    A photovoltaic module includes colorized reflective photovoltaic cells that act as pixels. The colorized reflective photovoltaic cells are arranged so that reflections from the photovoltaic cells or pixels visually combine into an image on the photovoltaic module. The colorized photovoltaic cell or pixel is composed of a set of 100 to 256 base color sub-pixel reflective segments or sub-pixels. The color of each pixel is determined by the combination of base color sub-pixels forming the pixel. As a result, each pixel can have a wide variety of colors using a set of base colors, which are created, from sub-pixel reflective segments having standard film thicknesses.

    A molecular dynamics simulation of nanosized particle collision under the electrical explosion of metal wires of different types was conducted. Interatomic interactions were described on the base of the embedded atom method. Used potentials allowed describing with high accuracy many mechanical and physical properties which are very important for the simulations of nanoparticle collisions with high velocities. The dynamics of the nanosized particle formation at the electric pulse explosion of metal wires of different types was studied. Features of particle collisions on the example of nanoscale particles of copper and nickel, whose velocities varied from 50 to 1500 m/s were investigated. The peculiarities of structural transformations in the colliding particles depending on the velocity of collision were determined. The intervals of collision velocities in which interaction between particles is elastic or leads to the formation of structural defects or melting were calculated. The analysis of the structure and distribution of chemical elements over the cross section of the particles which were synthesized under simultaneous explosions of different metal wires was carried out.

    The nature of science (NOS) has become a central goal of science education in many countries. This study refers to a developmental work research program, in which four fifth-grade elementary in-service teachers participated. It aimed to improve their understandings of NOS and their abilities to teach it effectively to their students. The 1-year-long, 2012-2013, program consisted of a series of activities to support teachers to develop their pedagogical content knowledge of NOS. In order to accomplish our goal, we enabled teacher-researchers to analyze their own discourse practices and to trace evidence of effective NOS teaching. Many studies indicate the importance of examining teachers' discussions about science in the classroom, since it is teachers' understanding of NOS reflected in these discussions that will have a vital impact on students' learning. Our proposal is based on the assumption that reflecting on the ways people form meanings enables us to examine and seek alternative ways to communicate aspects of NOS during science lessons. The analysis of discourse data, which has been carried out with the teacher-researchers' active participation, indicated that initially only a few aspects of NOS were implicitly incorporated in teacher-researchers' instruction. As the program evolved, all teacher-researchers presented more informed views on targeted NOS aspects. On the whole, our discourse-focused professional development program with its participatory, explicit, and reflective character indicated the importance of involving teacher-researchers in analyzing their own talk. It is this involvement that results in obtaining a valuable awareness of aspects concerning pedagogical content knowledge of NOS teaching.

    Full Text Available Mechanothermal (MT method is one of the methods used for large-scale production of carbon nanotubes/nanofibers. The different peculiar morphologies of carbon allotropes are introduced with an extraordinary structure for the first time by MT method. In this paper, the influence of milling time and annealing temperature on the crystallinity and morphology of the synthesized nanopowders was investigated. Surprisingly, in this investigation, we report the synthesis of springlike multiwalled carbon nanofibers (S-MWCNFs by a two-step annealing of milled graphite in an Ar atmosphere. On the other hand, the MT method could be used for the preparation of suitable structures with applications in nanocomposite materials, which is an important task in the era of nanotechnology.

    Full Text Available How can metallurgical terminology - specifically names of metals - support ar­ chaeological investigation? Can comparative linguistics and archaeology co-operate in order to identify the emergence and development of metallurgical skills? How did Neolithic and Bronze Age man imagine the taming of nature in order to achieve metal artifacts? Such questions -and many others -may arise whenever we try to investigate the beginnings and making of civilization. It is clear that the various aspects connected to archaeometallurgy cannot be analyzed separately from other aspects of human life, like agriculture, trade, urbanization, religious beliefs, early writing systems, pottery techniques, a.o. The earliest known (or identifiable names of metals do reflect a cer­ tain ideology and a certain way of 'seeing' metals as imbued with magic powers. It is certain that colours and reflections - specific to metals - made early man interpret them as divine (Biek and Bayley 1979; Muşu 1981, chapter Symphony of colours, a first attempt in reconstructing pre-Greek names of colours.

    Full Text Available Joseph Wresinski founded the ATD-Fourth World Movement in France in 1957 with the aim of eradicating poverty, as well as the exclusion and the lack of rights that go with it, in order to be able to model the structure of a society that has the most disadvantaged people in its centre. As an ordained priest of the Catholic Church, he created a secular organisation whose practice and ensuing principles are shaped by this peculiar duality. In order to demonstrate this facet, the first part of the present study gives a brief overview of Wresinski’s career, highlighting how the personal aspects of his life had influenced his views concerning the poorest, and more specifically, the principles and objectives of the Movement he founded. Thereafter, I address the particularities of the Movement, emphasizing its religious and social dimensions, in relation to the secular nature of French society. The two subchapters of the third part describe the two factors of the primordial relationship that constitutes the two, interdependent pillars of the Movement, emphasizing the relevant features of Wresinski’s vision concerning the poorest and also the volunteers engaged in the Movement. Finally, I intend to show how the pedagogical anthropology of Wresinski, with his radical interpretation of the Gospel, positions in its centre the man who, disfigured by poverty, is still the most authentic bearer of universal humanity, as he inseparably incorporates human rights and the divine filiation.

    Full Text Available Studying a biological species, we are very often obliged to examine many other species which are directly or indirectly related to the particular species in order to have broader perspective of its being. Interactions between organisms can be perceived on various levels concerning biological study areas, such as ecology, physiology, morphology etc. In this place, the authors have given some peculiar examples concerning parasitism. This specific interaction is very common in the animal kingdom, having in mind that about a half of all known organisms are parasitic. The importance of this phenomenon is reflected on many aspects of life, propelling evolution and speciation of each member in the relation.

    High-speed U-band photometry of the peculiar emission object MWC 560 obtained with the ground-based instrumentation, and V-band photometry obtained with the International Ultraviolet Explorer-Fine Error Sensor indicates irregular brightness variations are quasi-periodic. Multiple peaks of relative brightness power indicate statistically significant quasi periods existing in a range of 3-35 minutes, that are superposed on slower hourly varying components. We present a preliminary model that explains the minute and hourly time-scale variations in MWC 560 in terms of a velocity-shear instability that arises because a white dwarf magnetosphere impinges on an accretion disk. We also find evidence for Fe II multiplet pseudocontinuum absorption opacity in far-UV spectra of CH Cygni which is also present in MWC 560. Both CH Cyg and MWC 560 may be in an evolutionary stage that is characterized by strong UV continuum opacity which changes significantly during outburst, occurring before they permanently enter the symbiotic nebular emission phase.

    2010-11-01

    To review recent literature around the controversial diagnosis of personality disorder, and to assess the ethical aspects of its status as a medical disorder. The diagnostic currency of personality disorder as a psychiatric/medical disorder has a longstanding history of ethical and social challenges through critiques of the medicalization of deviance. More recently controversies by reflexive physicians around the inclusion of the category in the forthcoming revisions of International Classification of Diseases and Diagnostic and Statistical Manual of Mental Disorders classifications reflect the problems of value-laden criteria, with the diagnostic category being severely challenged from within psychiatry as well as from without. The clinical diagnostic criteria for extremely value-laden psychiatric conditions such as personality disorder need to be analyzed through the lens of values-based medicine, as well as through clinical evidence, as the propensity for political and sociolegal appropriation of the categories can render their clinical and diagnostic value meaningless.

    Three-dimensional (3D) high-aspect-ratio (HAR) microstructures for biomedical applications (e.g., microneedle, microadhesive, etc.) are microfabricated using the hybrid ultraviolet (UV) lithography in which inclined, rotational, and reverse-side UV exposure processes are combined together. The inclined and rotational UV exposure processes are intended to fabricate tapered axisymmetric HAR microstructures; the reverse-side UV exposure process is designed to sharpen the end tip of the microstructures by suppressing the UV reflection on a bottom substrate which is inevitable in conventional UV lithography. Hybrid UV lithography involves fabricating 3D HAR microstructures with an epoxy-based negative photoresist, SU-8, using our customized UV exposure system. The effects of hybrid UV lithography parameters on the geometry of the 3D HAR microstructures (aspect ratio, radius of curvature of the end tip, etc.) are measured. The dependence of the end-tip shape on SU-8 soft-baking condition is also discussed.

    2009-01-01

    Nuclear Fuel Plant (FCN) is a facility that produces fuel bundles of CANDU-6 type for the CANDU nuclear power plant. Only natural and depleted uranium in bulk and itemized form are present as nuclear materials in this facility. Uranium and wastes from the plant are handled, processed, treated and stored throughout the entire facility. The nuclear materials with natural and depleted uranium are entirely under nuclear safeguards. The amount of uranium present in the plant in different forms and activities together with zircaloy, beryllium and other hazardous substances, wastes, explosive materials at high temperatures, etc. lead to special measures undertaken by Nuclear Safety Department (DNS) to ensure nuclear safety. Different aspects of safety are continuously monitored in the plant: operational safety, industrial safety, radiological safety, labour safety, informational safety. The emergency preparedness and response, physical protection and the security of the plant and of the transportation of radioactive materials are contributing to cover the multitude of safety aspects. The safety culture of workers built directly on the safety components completes this activity in the plant. In addition the aspects of safety, security and safeguards are in permanent synergy, parts of the three components being included in each other. In the future the policy of FCN will be focused so that any improvement of one of the safety components will be reflected in improving the other safety aspects. (authors)

    To evaluate the importance of phenomenological aspects of the cognitive rumination (CR) construct in current empirical psychiatric research. We searched SciELO, Scopus, ScienceDirect, MEDLINE, OneFile (GALE), SpringerLink, Cambridge Journals and Web of Science between February and March of 2014 for studies whose title and topic included the following keywords: cognitive rumination; rumination response scale; and self-reflection. The inclusion criteria were: empirical clinical study; CR as the main object of investigation; and study that included a conceptual definition of CR. The studies selected were published in English in biomedical journals in the last 10 years. Our phenomenological analysis was based on Karl Jaspers' General Psychopathology. Most current empirical studies adopt phenomenological cognitive elements in conceptual definitions. However, these elements do not seem to be carefully examined and are indistinctly understood as objective empirical factors that may be measured, which may contribute to misunderstandings about CR, erroneous interpretations of results and problematic theoretical models. Empirical studies fail when evaluating phenomenological aspects of the cognitive elements of the CR construct. Psychopathology and phenomenology may help define the characteristics of CR elements and may contribute to their understanding and hierarchical organization as a construct. A review of the psychopathology principles established by Jasper may clarify some of these issues.

    2014-05-01

    Full Text Available The self-reflection on their own work has always been present in all designers, including architects and planners. In the mid 80-90 Donald Schön has made more explicit this aspect, which until then had not found a systematic scientific treatment.  The results of Schön are the basis of practical planning of the 90s period. However, the Schön's analysis reveals a context of knowledge of mental functioning typical of the conceiving period. From the 90s until now numerous advances in knowledge of the mechanisms of rationality, reflection and creativity have been made, and in this context we are interested in the progress made in the field of creativity.  We try to integrate and update the Schön's reflection with the new available theories such as the CK theory to offer planners a more innovated range of tools in order to understand and make better use of their creativity and self-reflection about their own creativity.

    Various mountain systems differ in character of landscapes and soil. Basic problem of present research: conditions and parameters determining the development of various landscapes and soils in mountain areas. Our research object is the area of Armenia where Small Caucasus, a part of Armenian upland is located. The specific character of the area is defined by the whole variety of all mountain structures like fold, block folding mountain ridges, volcanic upland, individual volcanoes, and intermountain depressions. As for the climate, the area belongs to dry subtropics. We have studied the peculiarities of high-altitude landscapes formation and mountain river basins development. We have used remote sensing data and statistic database of climatic parameters in this research. Field observations and landscape pictures analysis of space images allow distinguishing three types of mountain geosystems clearly: volcanic massifs, fold mountainous structures and closed high mountain basins - area of the lakes. The distribution of precipitation according to altitude shows some peculiarities. It has been found that due to this factor the investigated mountain area may be divided into three regions: storage (fold) mountainous area; Ararat volcanic area (southern macro exposure); closed high mountainous basin-area of the lake Sevan. The mountainous nature-climatic vertical landscapes appear to be horizontally oriented and they are more or less equilibrium (stable) geosystems, where the stable functional relationship between the landscape components is formed. Within their limits, definite bioclimatic structure of soil is developed. Along the slopes of fold mountains specific landscape shapes like litho-drainage basins are formed. They are intensively developing like relatively independent vertical geosystems. Mechanism of basin formation is versatile resulting in formation of the polychronous soil mantle structure. Landscapes and soils within the basin are of a different age, since

    Full Text Available The innovative development of the Russian economy in modern conditions should be based on the development of advanced nanotechnology. The formation of the nanotechnology industry in Russia requires optimal organization, the development of networking, the search for new forms of integrating the primary and secondary productions. The cluster organization in nanotech industry is based on high-tech production and has a number of advantages: uncertainty elimination, restriction of the competition by monopolization of supply with raw materials and semi-finished products, improvement of quality and decrease in expenses. The main forms of interaction of the enterprises and organizations which are a part of a nanoindustrial cluster are allocated. The article describes the peculiarities of the Russian nanoidustry formation, determines the significance of the cluster policy in this sphere. The author develops the criteria for identifying the nanoclusters on the basis of the basic nanotechnology and the nomenclature of final product. The author also proposes the approach to the analysis of cluster interaction and determines the boundaries of the cluster based on the difference between system and quasisystem cluster interaction. In this regard it is necessary to consider possibilities of the analysis of both system, and quasisystem interaction of the main participants of a nanoindustrial cluster.

    Full Text Available The article deals with the new situation in the education sector, which is characterized by the peculiarities of modern stage of the educational system’s development and by the necessity to rethink the principles of educational values in the XXI century through the prism of sustainable development’s priorities. Sociological ideas of phenomenology, which do not form social reality things or events of the material world in terms of supporters, have actively been used bu the authors and also the meaning given to these objects and events have been used in the article. Ontological and epistemological factors emergence of a new historical type of society, in our case, the information, have been disclosed from a philosophical position.  According to the authors, the state of postmodern society is primarily determined by culture. It is cultural society, which studies different external influences, including economic life, in the human world. Feature of modern social cognition that sets a new paradigm is as follows: it is carried out through the analysis of which representations had mediated self cognitive attitude to social phenomena, accompanied by the deep mentally communicative nature of social reality and brought changes in the socio-communicative sphere.

    Effects of the peculiar compositions in tea plant on free radicals induced by radiation was investigated. Results showed that the contents of free radicals in aborescence large-leaf varieties were more than that in shrubby middle-small leaf varieties under the same irradiation dose. Dose-effect curve for free radical contents in tea varieties could be described with an exponential equation. The contents of free radical and the radiosensitivities were related to the contents of catechin, tea polyphenols, flavone glycoside and caffeine. The main factor that affected free radical content in tea plant was catechin. Results also showed that there was a quantitative effect between (-)-EGCG and free radical: (-)-EGCG could induce the increase of free radical contents in tea at low concentration but scavenge free radicals at high concentration

    Self-reflection plays a key role in healthy human adaptation. Self-reflection might involve different capacities which may be impaired to different degrees relatively independently of one another. Variation in abilities for different forms of self-reflection are commonly seen as key aspects of many adult mental disorders. Yet little has been written about whether there are different kinds of deficits in self-reflection found in mental illness, how those deficits should be distinguished from one another and how to characterize the extent to which they are interrelated. We review clinical and experimental literature and suggest four different forms of deficits in self-reflection: (a) sense of ownership of one's own thoughts and actions, (b) emotional awareness, (c) distinction between fantasy and reality and (d) the integration of a range of different views of oneself and others. We propose how these different impairments in self-reflection are linked with one another.

    The paper is concerned with theoretical and practical aspects of the compaction process for powders of almost unstrained materials. Consideration from the standpoint of compressible body strain mechanics shows that such porous media may have a certain ''threshold'' density. Ductile characteristics of the porous material compacted up to this extent are identical with properties of compacrat bodies, i.e. there is a theoretically substantiated ban on a possibility of their further compaction without changing the state of the powder particle material. Theoretical conclusions are confirmed by results of experimental studies in compaction of titanium- containing ceramics [ru

    2009-05-01

    Interprofessional education (IPE) involves learning, and learning requires reflection. Educators need to "reflect more on reflection" if they are to be effective teachers in ensuring the learning outcomes essential for teamwork and interprofessional practice (IPP), including incorporating both theory and practice into the development of educational interventions. First, this discussion surveys the IPE-relevant literature on reflection, and then defines and refines the multidimensional concept of reflection as it relates to IPE in developing and implementing teamwork learning programs and experiences. Second, specific methods to promote reflection are presented and explored, including self-assessments, journaling, and written papers. Actual samples from student journals and assignments provide examples of the impacts of using these methods on participant reflection and learning. Finally, implications for an expanded understanding and application of reflection for IPE will be discussed, and recommendations made for educational practice and research in this area.

    In this paper I discuss the relationship between two different approaches to critical theory – the reflective and the receptive approaches. I show how it can be fruitful to discuss the relationship between Habermas and Foucault through this distinction. My point is that whereas Habermas focusses...... on critique as a reflexive activity, Foucault mainly focusses on the receptive conditions for critique to be possible. I argue further that Foucault focusses on the receptive aspects of critique, the quest for universality is not as pressing as it is in Habermas’ approach, because problematizing critique can...

    A limiting factor in ethics education in medical training has been difficulty in assessing competence in ethics. This study was conducted to test the concept that content analysis of pediatric residents' personal reflections about ethics experiences can identify changes in ethical sensitivity and reasoning over time. Analysis of written narratives focused on two of our ethics curriculum's goals: 1) To raise sensitivity to ethical issues in everyday clinical practice and 2) to enhance critical reflection on personal and professional values as they affect patient care. Content analysis of written reflections was guided by a tool developed to identify and assess the level of ethical reasoning in eight domains determined to be important aspects of ethical competence. Based on the assessment of narratives written at two times (12 to 16 months/apart) during their training, residents showed significant progress in two specific domains: use of professional values, and use of personal values. Residents did not show decline in ethical reasoning in any domain. This study demonstrates that content analysis of personal narratives may provide a useful method for assessment of developing ethical sensitivity and reasoning.

    The characteristics of the reflection and transmission by a fluid-loaded double porosity layer are studied. The medium obeys the two-pressure field poroelastic phenomenological model of Berryman and Wang. The open pore hydraulic conditions applied at the interfaces yield factorized expressions for the coefficients exhibiting on the one hand a separation allowing to distinguish between symmetrical and antisymmetrical motions and on the other hand the way each of the three dilatational waves associate with the shear wave. The numerical study done for a layer of Berea sandstone saturated by water shows clearly the role of each of the dilatational waves. There are peculiarities such as the absence of the fundamental antisymmetrical mode (zero order) and a singular behaviour of the symmetrical fundamental mode. The low frequency approximation for this latter is derived from the proposed formulas and compared with the numerical results. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available The modern world is interpreted and described in terms of an autobiographical society, in which the fundamental issues of human life are resolved in the process of an individual decision and being involved in a peculiar type of a dialog. This dialog is more and more often a dialog with oneself and an author’s vision of the world created in the confrontation with virtual reality. In this epoch context the biography is taken into account as a tool for perceiving, understanding and describing the change of the world and the human’s place in the world. Even though, the biography has functioned in social life forever, only now with the epoch of individualization, and then virtualization of life, its formative character has been noticed. Who is the subject of (autobiography? Who is it aimed at as a message and testimony of life? How is it created? Why is it constructed? Who is it constructed by? And then the questions which are behind the autobiography in the theoretical sense – What is life? How do we discover it? What is the link between telling about life and living the life? How is the telling (living about a life connected with culture and history? How does reading (interpreting about life connect with telling about life and the truth about life? Social development phases coupled with transformations within biographical reflection have been distinguished: life in a traditional world – the culture of telling about life; the birth of individualism (the individualization of experience – the culture of describing life; the discovery of identity – the culture of reading about life; life in the net and cyberspace – the culture of constructing life; the new communalism – the culture of seeking the meaning of life. Every stage of biographical reflection enables us to distinguish new forms of creating, understanding and using it in both the humanities and social life, but also in ordinary people’s life.

    Full Text Available The article presents the review of data obtained by foreign investigators and concerning a set of symptoms united by the umbrella term “sluggish cognitive tempo” (SCT. At present this complex of symptoms is regarded as typical for children with either attention deficit without hyperactivity or as a subtype of attention deficit syndrome. ChildrenwithSCT often look inhibited, they tend to plunge into their own flow of thoughts and imaginations during the work, feel drowsiness in day time.Accordingtotheempiricaldata the decrease in information processing speed, sustained attention and selective attention are typical for this category of children. A number of studies also indicatein them the deficit of visual information processing and a lack of some components regulating the executive function. A number of studies disclose the expressed inclination of children with SCT to anxiety and depressive disorders as well as to poor social contacts and maladaptation. There exists a hypothesisthat a significant deficit of motivation is typical for children with this kind of impairment. Yet, the diagnostic status of this symptom group as well as itsneuro-cognitive and emotion-personality peculiarities haven’t been found so far and need further investigating.

    The Valencian Autonomous Community approved at the end of last year the Law 10/2016 that modified several aspects of the territorial law that regulated different aspects about the appointment of senators in representation of the Autonomous Community. The new norm introduces, in a novel way in our right, the possibility of revocation of the senator appointed by the autonomic parliament, in addition to establishing the mandatory of the senator of appearance in the designating chamber as a form of accountability. The possibility of revocation of the senator due to loss of confidence of the autonomous chamber raises doubts of constitutionality by, among others, possible violation of the prohibition of imperative mandate of the members of the Cortes Generales, already resolved by STC 123/2017. This article, along the lines of the analysis of the Valencian norm and its constitutional reserve, reflects over the nature of the representative mandate and the peculiar function of the chamber of territorial representation.

    Full Text Available The acoustic and visual understanding of man is a hotly debated issue in contemporary culture. I found it important therefore to look at certain historical, cultural, aesthetical, philosophical and anthropological peculiarities of human image in Antiquity as reflected in the arts. The following aspects deserve special attention: the visualization of sense and values; the interaction of “ethos” (character and “soma” (body; the influence of the plastic images on the narrative ones; a normative typology of man; the significance of visual and acoustic perception. In this context, I studied ancient physiognomic; Aristotelian understanding of the acoustic and plastic arts; genesis, evolution and significance of the sculptural portrait image of man and the image of philosopher in Antiquity. I also pay attention to some methodological aspects of the study. As a result, there emerges an integral image of philosopher, which allows looking at the Greek culture from a fresh angle.

  12. Readiness for self-directed change in professional behaviours: factorial validation of the Self-Reflection and Insight Scale.

    Self-reflection, the practice of inspecting and evaluating one's own thoughts, feelings and behaviour, and insight, the ability to understand one's own thoughts, feelings and behaviour, are central to the self-regulation of behaviours. The Self-Reflection and Insight Scale (SRIS) measures three factors in the self-regulation cycle: need for reflection; engagement in reflection, and insight. We used structural equation modelling to undertake a confirmatory factor analysis of the SRIS. We re-specified our model to analyse all of the data to explain relationships between the SRIS, medical student characteristics, and responses to issues of teaching and learning in professionalism. The factorial validity of a modified SRIS showed all items loading significantly on their expected factors, with a good fit to the data. Each subscale had good internal reliability (> 0.8). There was a strong relationship between the need for reflection and engagement in reflection (r = 0.77). Insight was related to need for reflection (0.22) and age (0.21), but not to the process of engaging in reflection (0.06). Validation of the SRIS provides researchers with a new instrument with which to measure and investigate the processes of self-reflection and insight in the context of students' self-regulation of their professionalism. Insight is related to the motive or need for reflection, but the process of reflection does not lead to insight. Attending to feelings is an important and integral aspect of self-reflection and insight. Effective strategies are needed to develop students' insight as they reflect on their professionalism.

  13. Mast cell, the peculiar member of the immune system: A homeostatic aspect.

    2015-09-01

    The mast cell is a member of the immune system having a basic role in allergic (anaphylactic) reactions. However, it contains, synthesizes, stores and secretes lots of substances, which initiates other reactions or participates in them. These are in connection with the deterioration of tissue correlation, as malignant tumors, angiogenesis, wound healing, pregnancy and different pathological conditions. In addition - as other members of the immune system - mast cells can synthesize, store and secrete hormones characteristic to the endocrine glands and can transport them to the site of requirement (packed transport), or produce and employ them locally. The effect of mast cells is controversial and frequently dual, stimulatory or inhibitory to the same organ or process. This is likely due to the heterogeneity of the mast cells, in morphology and cell content alike and dependent on the actual condition of the targeted tissue. The cells are transported in an unmatured form by the blood circulation and are exposed to microenvironmental effects, which influence their maturation. Their enrichment around tumors suggested using them as targets for tumor therapy more than fifty years ago (by the author), however, this idea lives its renaissance now. The review discusses the facts and ideas critically.

    Full Text Available Reconstruction of the penis in transgender operations, amputation of the penis, congenital deformities and anomalies of the penis was and remains today an important issue in plastic surgery of the urogenital region. The only method to restore the penis is phalloplasty. In general, over the past decades, generations of clinicians have different ways and flaps for total fallouretheral reconstruction. Thus was formulated the characteristics of an ideal flap for the formation of neophallos, which should be safe, sensitive, without hair, and with long leg. However, despite the fact that the characteristics of a perfect flap, nowadays there is no “gold standard” in the formation of neophallos, as phalloplasty is a fairly complicated surgery, and the choice of method depends on many factors. The choice of methodology is determined by the plastics surgeon and to each patient is individual, depends on the etiology of the disease and the possibility of choosing the form of the donor’s transplant. This article presents a literature review devoted to the historical aspects of phalloplasty. In the article, in chronological order reflected the evolution of the different forming methods neofallos, phallourethrоplasty, describes their advantages and disadvantages.

  15. Bio-inspired, subwavelength surface structures to control reflectivity, transmission, and scattering in the infrared

    Science.gov (United States)

    Lora Gonzalez, Federico

    Controlling the reflection of visible and infrared (IR) light at interfaces is extremely important to increase the power efficiency and performance of optics, electro-optical and (thermo)photovoltaic systems. The eye of the moth has evolved subwavelength protuberances that increase light transmission into the eye tissue and prevent reflection. The subwavelength protuberances effectively grade the refractive index from that of air (n=1) to that of the tissue (n=1.4), making the interface gradual, suppressing reflection. In theory, the moth-eye (ME) structures can be implemented with any material platform to achieve an antireflectance effect by scaling the pitch and size of protuberances for the wavelength range of interest. In this work, a bio-inspired, scalable and substrate-independent surface modification protocol was developed to realize broadband antireflective structures based on the moth-eye principle. Quasi-ordered ME arrays were fabricated in IR relevant materials using a colloidal lithography method to achieve highly efficient, omni-directional transmission of mid and far infrared (IR) radiation. The effect of structure height and aspect ratio on transmittance and scattering is explored, with discussion on experimental techniques and effective medium theory (EMT). The highest aspect ratio structures (AR = 9.4) achieved peak single-side transmittance of 98%, with >85% transmission for lambda = 7--30 microns. A detailed photon balance constructed by transmission, forward scattering, specular reflection and diffuse reflection measurements to quantify optical losses due to near-field effects will be discussed. In addition, angle-dependent transmission measurements showed that moth-eye structures provide superior antireflective properties compared to unstructured interfaces over a wide angular range (0--60° incidence). Finally, subwavelength ME structures are incorporated on a Si substrate to enhance the absorption of near infrared (NIR) light in PtSi films to

    2017-09-01

    Different concepts of the development of geo-mechanical processes during longwall mining of a seam which are fundamentally different from the conventional ones are introduced in the article. Fundamental principles of the model for structurizing enclosing rock mass while longwall mining along the strike are described. The model was developed on the bases of non-linear geomechanical laws. According to the model, rock mass in the area of mining operation is organized as rock geomechanical layers with shifting arches. And the formation period of shifting arches in disintegrated rock mass is divisible by the length of the stope. Undulate characteristic of a massif as a peculiarity of man-made structurization of a massif is defined. It is shown that structuring the broken massif causes the formation of block-structured system and it can be detected while monitoring the ground pressure in powered support props. The results of the research allow decreasing the negative influence of a ground pressure and can be applied to specify parameters for controlling the roof, defining geometrical dimensions of a mining section and positioning of holing chute (face entry).

    Peculiarities of approximation for reactor neutron energy spectra during radiation defects computerized simulation were discussed. Approximation of neutron spectra N(E) was carried out by N(E)=α·exp(-β·E)·sh(γ·E) formula (1), where α, β, γ - approximation coefficients. In the capacity of operating reactor data experimental data on 235 U and 239 Pu were applied. The algorithm was designed, and acting soft ware for spectra parameters calculation was developed. The following values of approximation parameters were obtained: α=80.8; β=0.935;γ=2.04 (for uranium and plutonium these coefficients are less distinguishing). Then with use of formula 1 and α, β, γ coefficients the approximation curves were constructed. These curves satisfactorily describe existing experimental data and allowing to use its for radiation defects simulation in the reactor materials

    Student evaluations can help clinical teachers to reflect on their teaching skills and find ways to improve their teaching. Studies have shown that the mere presentation of student evaluations is not a sufficient incentive for teachers to critically reflect on their teaching. We evaluated and compared the effectiveness of two feedback facilitation strategies that were identical except for a peer reflection meeting. In this study, 54 clinical teachers were randomly assigned to two feedback strategies. In one strategy, a peer reflection was added as an additional step. All teachers completed a questionnaire evaluating the strategy that they had experienced. We analysed the reflection reports and the evaluation questionnaire. Both strategies stimulated teachers to reflect on feedback and formulate alternative actions for their teaching practice. The teachers who had participated in the peer reflection meeting showed deeper critical reflection and more concrete plans to change their teaching. All feedback strategies were considered effective by the majority of the teachers. Strategies with student feedback and self-assessment stimulated reflection on teaching and helped clinical teachers to formulate plans for improvement. A peer reflection meeting seemed to enhance reflection quality. Further research should establish whether it can have lasting effects on teaching quality.

    Full Text Available Objective: To evaluate the importance of phenomenological aspects of the cognitive rumination (CR construct in current empirical psychiatric research.Method: We searched SciELO, Scopus, ScienceDirect, MEDLINE, OneFile (GALE, SpringerLink, Cambridge Journals and Web of Science between February and March of 2014 for studies whose title and topic included the following keywords: cognitive rumination; rumination response scale; and self-reflection. The inclusion criteria were: empirical clinical study; CR as the main object of investigation; and study that included a conceptual definition of CR. The studies selected were published in English in biomedical journals in the last 10 years. Our phenomenological analysis was based on Karl Jaspers' General Psychopathology.Results: Most current empirical studies adopt phenomenological cognitive elements in conceptual definitions. However, these elements do not seem to be carefully examined and are indistinctly understood as objective empirical factors that may be measured, which may contribute to misunderstandings about CR, erroneous interpretations of results and problematic theoretical models.Conclusion: Empirical studies fail when evaluating phenomenological aspects of the cognitive elements of the CR construct. Psychopathology and phenomenology may help define the characteristics of CR elements and may contribute to their understanding and hierarchical organization as a construct. A review of the psychopathology principles established by Jasper may clarify some of these issues.

  20. Patient experience and satisfaction with inpatient service: development of short form survey instrument measuring the core aspect of inpatient experience.

    Eliza L Y Wong

    Full Text Available Patient experience reflects quality of care from the patients' perspective; therefore, patients' experiences are important data in the evaluation of the quality of health services. The development of an abbreviated, reliable and valid instrument for measuring inpatients' experience would reflect the key aspect of inpatient care from patients' perspective as well as facilitate quality improvement by cultivating patient engagement and allow the trends in patient satisfaction and experience to be measured regularly. The study developed a short-form inpatient instrument and tested its ability to capture a core set of inpatients' experiences. The Hong Kong Inpatient Experience Questionnaire (HKIEQ was established in 2010; it is an adaptation of the General Inpatient Questionnaire of the Care Quality Commission created by the Picker Institute in United Kingdom. This study used a consensus conference and a cross-sectional validation survey to create and validate a short-form of the Hong Kong Inpatient Experience Questionnaire (SF-HKIEQ. The short-form, the SF-HKIEQ, consisted of 18 items derived from the HKIEQ. The 18 items mainly covered relational aspects of care under four dimensions of the patient's journey: hospital staff, patient care and treatment, information on leaving the hospital, and overall impression. The SF-HKIEQ had a high degree of face validity, construct validity and internal reliability. The validated SF-HKIEQ reflects the relevant core aspects of inpatients' experience in a hospital setting. It provides a quick reference tool for quality improvement purposes and a platform that allows both healthcare staff and patients to monitor the quality of hospital care over time.

    This article develops the concept media for reflection in the interest of conceptualizing the interpretative frames that enable and limit reflection in management and leadership education. The concept ‘media for reflection’ allows us to conceptualize the social and cultural mediation of reflection...... without reducing reflection to an effect of the social structures and cultural norms in which it is embedded. Based on the developed theoretical framework, this article analyses how a renaissance ‘mirror for princes’ and contemporary research-based management education mediate reflection. The content...... of the mediations is analysed as well as the societal and organizational background. Furthermore, the means by which the two media enable and limit reflection in different ways is compared.

    Full Text Available The purpose of the research is to ground and develop the methods of the use of dancing exercises at physical training classes in high school and to experimentally verify their effectiveness. Research methods. Theoretical ones: study and analysis of pedagogical, scientific and methodological literature on the problems under research; a complex of empirical research methods: research and experimental work, observations, questionnaires, testing; statistical methods of research and data reduction. Research results. The paper reveals the peculiarities of the use of dancing exercises at physical training classes in high school. It shows that dancing exercises can and must be part of the physical education of high schoolers to develop their strength, flexibility, endurance, coordination abilities and to cultivate movement culture, musicality, dancing abilities and aesthetic taste. The study proves that the use of dancing exercises of classical choreography, rhythmic gymnastics and health-improving aerobics at the physical training classes in high school helps increase the level of development of flexibility, strength and agility.

    Full Text Available Background. Leading criteria for laboratory diagnosis and determination of diabetic ketoacidosis severity are considered to be the levels of glucose, blood pH and blood bicarbonate. Technological capabilities of a family doctor are very limited. Therefore, knowledge of detailed clinical symptoms will help the physician to establish correctly a provisional diagnosis and refer a patient to a specialized institution. The aim of our study was to determine the prevalence and special features of certain clinical symptoms and basic laboratory parameters in order to establish the severity level of diabetic ketoacidosis (DKA and to reveal certain correlation between clinical symptoms and laboratory changes in the blood in patients with DKA. Materials and methods. The study involved 123 patients with acute critical decompensated diabetes aged from 9 to 65 years old. We studied the clinical symptoms, measured biochemical changes in blood, blood gas and acid-base state. Results. There was not determined the correlation between severity of diabetic ketoacidosis and clinical parameters and acid-base balance in patients. There were determined the peculiarities electrolyte changes and the emergence gas metabolic changes on the cell level under ketosis, which further deepened with the development of ketoacidosis. The results of the study indicate the need for a comparison of clinical symptoms and laboratory parameters of pathogenic treatment, taking into account the cumulative data. These recommendations in the protocols are often attached to a single laboratory value and can not always fully comply with the severity of the condition. Conclusions. Blood gas is the most sensitive criterion of metabolic changes in case of diabetic ketoacidosis. The level of blood potassium can be used as an indicator of DKA severity. The level of blood potassium at admission to hospital does not really reflect its deficiency in the tissues.

    2007-11-01

    Due to increasing immigration in Germany the German Mental Health Care System today has to deal in a growing number with the assessment of the level of psychic functioning and the capability of self control in patients of different ethnic origin. For clinicians this is a challenge, since suicidal behaviour in terms of its frequency, meaning, motives and manner is very much dependent on the cultural context in which it occurs. Moreover, the general attitude of an individual towards suicide is embedded in the culture of origin of the immigrant. Until now there has been only little systematic research on the influence of culture on suicidal behaviour. In this review the traditions of suicidal behaviour in different cultures in their religious and historical dimensions will be reflected. The historical and cultural roots of suicidal behaviour will be put in context to a categorization of the different variants of suicide, such as institutionalized suicide versus individualized suicide. Psychodynamic aspects of suicidal ideation will be highlighted in cross-cultural perspective with a distinction between a. the wish to die, b. the wish to kill and c. the wish to be killed. It will be shown that there can be differentiated between accepted and non-accepted suicide. With respect to epidemiology there will be discussed the impact of culture on the suicide rates across cultures. The influence of culture on the psychopathology of suicidal behaviour will be summed up systematically. These aspects are of high relevance for the understanding and assessment of suicidal crisis in immigrants, since the suicidal patient even today - although subconsciously - is influenced by the deep rooted traditions of suicidal behaviour in his culture of origin.

    2006-12-01

    We construct a semiclassical theory for propagation of an optical wave packet in a nonconducting medium with a periodic structure of dielectric permittivity and magnetic permeability, i.e., a nonconducting photonic crystal. We employ a quantum-mechanical formalism in order to clarify its link to those of electronic systems. It involves the geometrical phase, i.e., Berry's phase, in a natural way, and describes an interplay between orbital motion and internal rotation. Based on the above theory, we discuss the geometrical aspects of the optical Hall effect. We also consider a reduction of the theory to a system without periodic structure and apply it to the transverse shift of an optical beam at an interface reflection or refraction. For a generic incident beam with an arbitrary polarization, an identical result for the transverse shift of each reflected or transmitted beam is given by the following different approaches: (i) analytic evaluation of wave-packet dynamics, (ii) total angular momentum (TAM) conservation for individual photons, and (iii) numerical simulation of wave-packet dynamics. It is consistent with a result by classical electrodynamics. This means that the TAM conservation for individual photons is already taken into account in wave optics, i.e., classical electrodynamics. Finally, we show an application of our theory to a two-dimensional photonic crystal, and propose an optimal design for the enhancement of the optical Hall effect in photonic crystals.

    Reis, Shmuel P.

    2010-01-01

    Reflective capacity has been described as an essential characteristic of professionally competent clinical practice, core to ACGME competencies. Reflection has been recently linked to promoting effective use of feedback in medical education and associated with improved diagnostic accuracy, suggesting promising outcomes. There has been a proliferation of reflective writing pedagogy within medical education to foster development of reflective capacity, extend empathy with deepened understanding of patients’ experience of illness, and promote practitioner well-being. At Alpert Med, “interactive” reflective writing with guided individualized feedback from interdisciplinary faculty to students’ reflective writing has been implemented in a Doctoring course and Family Medicine clerkship as an educational method to achieve these aims. Such initiatives, however, raise fundamental questions of reflection definition, program design, efficacy of methods, and outcomes assessment. Within this article, we consider opportunities and challenges associated with implementation of reflective writing curricula for promotion of reflective capacity within medical education. We reflect upon reflection. PMID:20407840

    BAL lymphocyte percentages, quantitated gallium-67 lung uptake, and SACE levels have all been proposed as measures of disease activity in sarcoidosis. We analyzed 32 paired sera and BAL fluids from sarcoidosis patients by high-resolution agarose electrophoresis to look for protein changes characteristic of systemic or local inflammation and compared the results with those from the above tests. Nine patients (group 1) had serum inflammatory protein changes and increased total protein, albumin, beta 1-globulin (transferrin), and gamma-globulin levels in fluid recovered by BAL. Thirteen patients (group 2) had normal protein levels in sera but abnormal protein levels in BAL specimens. Ten patients (group 3) had normal protein levels in sera and in BAL specimens. Patients in groups 1 and 2 had a disproportionate increase in beta 1-globulin (transferrin) and gamma-globulin levels in their BAL specimens. The BAL lymphocyte percentage changes paralleled the BAL protein level changes, suggesting relationships among the immunoregulatory role of these cells, increased local immunoglobulin synthesis, and the pathogenesis of altered alveolar permeability. Gallium-67 uptake was highest in patients with serum inflammatory protein changes. Thus, systemic inflammation may facilitate pulmonary gallium-67 uptake, possibly by changes in BAL fluid or serum transferrin saturation and/or kinetics. SACE levels showed no relationship to changes in the levels of serum or BAL proteins. These data suggest that the various proposed measures of disease activity reflect different aspects of inflammation in sarcoidosis

This presents, almost unexpectedly and suddenly, two types of reflection (1 reflection on action which occurs during the action interrupting and interfering with it, and (2 reflections in action which appears in the action as well as in the disruption and interruption, so that we think about her and about how to reshape the action that takes place in the moments of reflection. The idea of reflective practitioners (educators, adult educators, sociologists, etc., or a practitioner who thinks about his/her own practice and the practice of reflection draws on its theoretical origins that Schon develops almost like an original idea that became well-known. He assumes that the practice of practical activities (such as teaching, instruction, therapeutic work of doctors or therapists constitutes an original and very specific epistemology. Contrary to the dominant technical rationality that underpins modern professional education, Schon believes that professional knowledge and competence includes the effect of successful practitioners (educators, adult educators, teachers, etc., especially in reflection-in-action (''reflection of what we do while doing'' (Schon, 1986, which appears in problem situations. Hence, the practical education of the profession, according to the author, necessarily follows the model of learning by doing a particular kind of apprenticeship modelled on the training of musicians, artists and drama artists. In his second book (The Reflective Practitioner, Schon develops reflective practicum and confronts it with a dominant, normative curriculum, which constitutes the basis of theoretical knowledge to solve practical, instrumental problems. Practice, however, that is often characterized by uncertainty in this case does not become one solution, but the solution depends on the choice of the value of paragraph, depending on what aspect of the situation we pay more attention to. Schon distinguishes knowledge in action, what implicit knowledge is

    2015-01-01

    Despite its long history and stunning experimental successes, the mathematical foundation of perturbative quantum field theory is still a subject of ongoing research. This book aims at presenting some of the most recent advances in the field, and at reflecting the diversity of approaches and tools invented and currently employed. Both leading experts and comparative newcomers to the field present their latest findings, helping readers to gain a better understanding of not only quantum but also classical field theories. Though the book offers a valuable resource for mathematicians and physicists alike, the focus is more on mathematical developments. This volume consists of four parts: The first Part covers local aspects of perturbative quantum field theory, with an emphasis on the axiomatization of the algebra behind the operator product expansion. The second Part highlights Chern-Simons gauge theories, while the third examines (semi-)classical field theories. In closing, Part 4 addresses factorization homolo...

    This book provides a modern introductory tutorial on specialized theoretical aspects of spatial and temporal modeling. The areas covered involve a range of topics which reflect the diversity of this domain of research across a number of quantitative disciplines. For instance, the first chapter provides up-to-date coverage of particle association measures that underpin the theoretical properties of recently developed random set methods in space and time otherwise known as the class of probability hypothesis density framework (PHD filters). The second chapter gives an overview of recent advances in Monte Carlo methods for Bayesian filtering in high-dimensional spaces. In particular, the chapter explains how one may extend classical sequential Monte Carlo methods for filtering and static inference problems to high dimensions and big-data applications. The third chapter presents an overview of generalized families of processes that extend the class of Gaussian process models to heavy-tailed families known as alph...

    A two-layer model was developed in our earlier studies to estimate the clear sky reflectance enhancement near clouds. This simple model accounts for the radiative interaction between boundary layer clouds and molecular layer above, the major contribution to the reflectance enhancement near clouds for short wavelengths. We use LES/SHDOM simulated 3D radiation fields to valid the two-layer model for reflectance enhancement at 0.47 micrometer. We find: (a) The simple model captures the viewing angle dependence of the reflectance enhancement near cloud, suggesting the physics of this model is correct; and (b) The magnitude of the 2-layer modeled enhancement agree reasonably well with the "truth" with some expected underestimation. We further extend our model to include cloud-surface interaction using the Poisson model for broken clouds. We found that including cloud-surface interaction improves the correction, though it can introduced some over corrections for large cloud albedo, large cloud optical depth, large cloud fraction, large cloud aspect ratio. This over correction can be reduced by excluding scenes (10 km x 10km) with large cloud fraction for which the Poisson model is not designed for. Further research is underway to account for the contribution of cloud-aerosol radiative interaction to the enhancement.

    Full Text Available Employment of applicants of pharmaceutical higher education has both positive and negative impact on the quality of educational services provided by institutions, especially in terms of knowledge and skills acquired by student. Objective is to study peculiarities of higher education employment, full-time training, and features driving them to conclude labor agreements. Materials and methods. During the study, we used juridical and comparative legal methods of analysis. Results. The study has defined the following features of the employment of applicants of higher education in the health care institutions, pharmaceutical enterprises and organizations. The current legislation provides the applicants of higher education enrolled in HEIs for full-time training with a right to make a free choice of the field of study, profession, type of occupation and work. The relationship developed between an applicant and higher education institutions are not to be regarded as an employment relationship. The working under the items of labor agreement for person who combine it with the full-time education is not a part or combination or sharing, and is considered the main place of job. Thus, it stipulates maintenance of records book of the employed worker according to the general procedure. An applicant of higher education has discretion to choose working hours (full- or part-time working day, full- or part-time working week with taking into consideration the HEIs schedule and only in the free time. When full-time operating in frameworks of collective agreement at enterprise, institution, or organization, having accounted peculiarities of operation, non-standardized working day for some positions can be set. The current legislation stipulates possibility of employment for persons without higher pharmaceutical education to the health care institutions on the clearly defined positions. Conclusions.The country authority has created and is providing favorable

    Full Text Available We investigated whether brain potentials of grammatical aspect processing resemble semantic or morpho-syntactic processing, or whether they instead are characterized by an entirely distinct pattern in the same individuals. We studied aspect from the perspective of agreement between the temporal information in the context (temporal adverbials, e.g., Right now and a morpho-syntactic marker of grammatical aspect (e.g., progressive is swimming. Participants read questions providing a temporal context that was progressive (What is Sophie doing in the pool right now? or habitual (What does Sophie do in the pool every Monday?. Following a lead-in sentence context such as Right now, Sophie…, we measured ERPs time-locked to verb phrases in four different conditions, e.g., (a is swimming (control; (b *is cooking (semantic violation; (c *are swimming (morpho-syntactic violation; or (d?swims (aspect mismatch; …in the pool. The collected ERPs show typical N400 and P600 effects for semantics and morpho-syntax, while aspect processing elicited an Early Negativity (250-350 ms. The aspect-related Negativity was short-lived and had a central scalp distribution with an anterior onset. This differentiates it not only from the semantic N400 effect, but also from the typical (LAN (Left Anterior Negativity, that is frequently reported for various types of agreement processing. Moreover, aspect processing was not accompanied by a clear P600 modulation.We argue that the specific context for each item in this experiment provided a trigger for agreement checking with temporal information encoded on the verb, i.e., morphological aspect marking. The aspect-related Negativity obtained for aspect agreement mismatches reflects a violated expectation concerning verbal inflection (in the example above, the expected verb phrase was Sophie is X-ing rather than Sophie X-s in condition d. The absence of an additional P600 for aspect processing suggests that the mismatch did not

    ISAGEN designed and applied a multi-aspect methodology to classify and compare projects of the company's electricity generation options portfolio. It was developed from a holistic vision, integrating multidisciplinary information from the economic, environmental and technical aspects. This helped to classify the alternatives based on the sum of the values obtained for the different considered aspects. This document presents, in general form, the procedure adopted for the index formulation and selection of factors including the variables corresponding to the sub-aspects (or environmental dimensions) physical, biotic and social. The investigation's work, selection and classification of the variables were developed by an interdisciplinary group of experimented professionals in the environmental evaluation of projects. The integration of the three sub-aspects (physical, biotic and social) resulted in a hierarchy of projects based on environmental considerations, which were finally articulated with the respective values obtained from the technical and economical aspects. In general, the results obtained in each sub-aspect agreed with the hierarchy of projects based on an expert concept previous to the method application. In synthesis, it was observed that this technique is of great utility to make comparisons and general classifications because it allows to take advantage of information with different characteristics and include assumptions or artificial modifiable methodological items that reflect the structure of the deciding agents preferences at any given time
