Understanding and treating incompleteness in obsessive-compulsive disorder

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 11 2004
Laura J. SummerfeldtArticle first published online: 10 SEP 200
Incompleteness,the troubling and irremediable sense that one's actions or experiences are not "just right",appears to underlie many of the symptoms of obsessive-compulsive disorder (OCD). Because incompleteness may reflect basic sensory-affective dysfunction, it presents a challenge to clinicians wishing to apply cognitive-behavioral treatments. In this article, I review ways of adapting well-demonstrated treatment principles to this condition. A case is presented and then used to discuss challenges in conducting cognitive-behavioral therapy with this population. Behavioral methods aimed at habituation (e.g., exposure and ritual prevention [ERP]) are probably more applicable than conventional cognitive techniques. However, even these may result in modest long-term gains; relapse is a probability if they are not actively practiced after treatment cessation. © 2004 Wiley Periodicals, Inc.

Sampling and concentration values of incomplete bibliographies

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 4 2002
L. Egghe
This article studies concentration aspects of bibliographies. More, in particular, we study the impact of incompleteness of such a bibliography on its concentration values (i.e., its degree of inequality of production of its sources). Incompleteness is modeled by sampling in the complete bibliography. The model is general enough to comprise truncation of a bibliography as well as a systematic sample on sources or items. In all cases we prove that the sampled bibliography (or incomplete one) has a higher concentration value than the complete one. These models, hence, shed some light on the measurement of production inequality in incomplete bibliographies. [source]


Contradiction as a form of Contractual Incompleteness,

THE ECONOMIC JOURNAL, Issue 530 2008
Dana Heller
A simple model is presented, in which contradictory instructions are viewed as a type of contract incompleteness. The model provides a complexity-based rationale for contradictory instructions. If there are complexity bounds on the contract, there may be an incentive to introduce contradictions, leaving for another agent the task of interpreting them. The optimal amount of contradictions depends on the complexity bound, the conflict of interests with the interpreter and the institutional constraints on his interpretations. In particular, a higher complexity bound may result in a larger amount of contradictions. [source]


Lopingian (Late Permian) high-resolution conodont biostratigraphy in Iran with comparison to South China zonation

GEOLOGICAL JOURNAL, Issue 2-3 2010
Shu-Zhong Shen
Abstract Lopingian (Late Permian) conodonts and stratigraphy in northwest and central Iran have become hotly debated issues recently. We here use a sample-population approach, to develop a high-resolution conodont biostratigraphic framework for the Lopingian of Iran based on a re-examination of collections studied by Sweet from the Kuh-e-Ali Bashi area, northwest Iran; samples from the Abadeh C section and a nearby Permian-Triassic boundary section in the Abadeh area; and on published data. Six Wuchiapingian conodont zones, the Clarkina dukouensis, C. asymmetrica, C. leveni, C. guangyuanensis, C. transcaucasica and C. orientalis zones, and eight Changhsingian conodont zones, the Clarkina wangi, C. subcarinata, C. changxingensis, C. bachmanni, C. nodosa, C. yini, C. abadehensis and C. hauschkei zones, are described and figured. Diagnoses of ontogenetic characteristics to population variations of all the zone-naming species are re-described based on a sample-population taxonomic concept. The high-resolution Lopingian conodont zonation in Iran is closely correlative with its counterpart in South China. However, slightly different evolutionary trends in Clarkina populations existed at the very end of the Changhsingian in Iran and South China. This reflects a geographical cline and/or facies dependence and endemism in Clarkina populations rather than stratigraphic incompleteness of sections in either Iran or South China.

Does versatility as measured by geographic range, bathymetric range and morphological variability contribute to taxon longevity?

GLOBAL ECOLOGY, Issue 1 2007
Lee Hsiang Liow
ABSTRACT Aim, This paper aims to examine the relationship between versatility as measured by geographic range, bathymetric range and morphological variability (species and subspecies richness and the occurrence of morphologically highly variable populations), and the geologic longevities of trachyleberidid ostracode species and genera, while accounting for sampling biases and other confounding factors. Location, Global. Methods, A large database of occurrence records of species of the family Trachyleberididae s.l. was analysed. The relationships between genus and species longevity and the above mentioned variables were examined singly and in concert. Re-analyses of subsets of data and rarefaction techniques were employed to account for sampling biases, while randomization was used to account for autocorrelation of variables. Results, The mean number of occurrence records, and latitudinal and longitudinal ranges, were strongly and positively correlated with genus and species longevities. The number of bathymetric zones occupied by genera had no consistent bearing on their longevities, but species data subsets tended to indicate significant positive relationships between bathymetric range and longevities. Species richness was significantly and positively correlated with genus longevities. Species and genera with subspecies and species with high morphological variability all had significantly greater longevities. Genus-level characteristics can be explained largely by species-level characteristics, including longevity, latitudinal ranges and bathymetric ranges to a lesser degree. However, genus longevity was best explained by species richness and genus age, even for extinct genera, while species longevity was best explained by species latitudinal range. Main conclusions, In spite of the incompleteness of the fossil record, we can control for biasing factors and still confidently draw the conclusion that both ecological and evolutionary versatility contribute to lineage longevity, beyond the shorter temporal observation windows available to most ecological studies.

A comparative simulation study of work processes in autonomous production cells

HUMAN FACTORS AND ERGONOMICS IN MANUFACTURING & SERVICE INDUSTRIES, Issue 1 2002
Christopher Schlick
An approach to human-centered design and assessment of work processes in flexible manufacturing systems with the help of dynamic task networks is presented. To model and simulate the task networks, the method of timed colored Petri Nets is used. Two task networks are developed. The first task network is a model of work processes in Autonomous Production Cells (APCs). The second task network represents work processes in conventional Computer Numerically Controlled (CNC)-based manufacturing systems. The material processing technology is associated with 5-axis milling. The values of attributes of task elements were acquired empirically on a fine-grained level with reference to a sample milling order. Comparative hypotheses regarding time-on-task, supervisory control functions, levels of cognitive control, human error (HE), and labor division were then formulated. To test these hypotheses, several simulation experiments were conducted. The results from inferential statistics show that single-operator APCs have a 30% higher efficiency in relation to total time-on-task. Moreover, the level of cognitive control is significantly shifted toward rule- and knowledge-based behavior. Surprisingly, the simulation of minor HE does not demonstrate a significantly worse performance from APCs. A simulated labor division among central process planner and production operator allows an additional efficiency improvement of approximately 15%. However, the labor division has two important drawbacks: first, a sequential incompleteness of operators' task spectrum occurs; second, the operator has to cope with hierarchical task incompleteness. Finally, a sensitivity analysis was carried out to investigate the effects of varying lot sizes and number of processed orders. © 2002 John Wiley & Sons, Inc. [source]


Assessing the reliability of biodiversity databases: identifying evenly inventoried island parasitoid faunas (Hymenoptera: Ichneumonoidea) worldwide

INSECT CONSERVATION AND DIVERSITY, Issue 2 2010
ANA M. C. SANTOS
Abstract., 1.,Taxonomic and geographic biases are common in biodiversity inventories, especially in hyperdiverse taxa, such as the Ichneumonoidea. Despite these problems, biodiversity databases could be a valuable source of information if their reliability is carefully assessed. 2.,One major problem of using these data for large-scale analyses is the unevenness of data quality from different areas, which makes them difficult to compare. One way of surpassing such problem would be to identify sets of areas that are evenly inventoried. 3.,Here, we propose a scoring protocol for the identification of sets of evenly inventoried areas from taxonomic databases, based on three criteria: (i) completeness at high taxonomic levels, (ii) congruence with well-established ecological relationships (such as species,area relationship), and (iii) publication effort received. We apply this protocol to the selection of a set of evenly inventoried islands worldwide for two Ichneumonoidea families (Braconidae and Ichneumonidae) from the data gathered in Taxapad database. 4.,From the 118 islands included in Taxapad, 53 and 70 can be considered sufficiently inventoried for Braconidae and Ichneumonidae, respectively. The publication effort criterion was more restrictive than the other two criteria. The Indomalayan, Nearctic and Palearctic regions had more than half of their islands identified as evenly inventoried, for both families. 5.,We discuss the generality of the biases and incompleteness of most biodiversity data, and also how the basic principles of the protocol proposed here can be applied to taxonomic databases devoted to other taxa. Also, the islands identified here can serve as the basis for large-scale analyses of the poorly known biogeography of the Ichneumonoidea. [source]


Risk-free bond prices in incomplete markets with recursive multiple-prior utilities

INTERNATIONAL JOURNAL OF ECONOMIC THEORY, Issue 2 2006
Chiaki Hara
D52; D91; E21; E44; G12 We consider an exchange economy under uncertainty, in which agents' utility functions may be recursive and the expected utility calculation may be based on multiple priors. The utility functions representing risk attitudes and intertemporal substitution are negative exponential functions. These utility functions and the access to asset markets may arbitrarily differ across agents. We prove that the risk-free bond price goes down (and the interest rate goes up) monotonically as the market incompleteness diminishes. We also find the range of equilibrium bond prices that depends on the primitives of the economy but not on the structures of asset markets. [source]


An introduction to bipolar representations of information and preference

INTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 8 2008
Didier Dubois
Bipolarity seems to pervade human understanding of information and preference, and bipolar representations look very useful in the development of intelligent technologies. Bipolarity refers to an explicit handling of positive and negative sides of information. Basic notions and background on bipolar representations are provided. Three forms of bipolarity are laid bare: symmetric univariate, dual bivariate, and asymmetric (or heterogeneous) bipolarity. They can be instrumental in the logical handling of incompleteness and inconsistency, rule representation and extraction, argumentation, learning, and decision analysis. © 2008 Wiley Periodicals, Inc.

Distribution-based anomaly detection in 3G mobile networks: from theory to practice

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 5 2010
Alessandro D'Alconzo
The design of anomaly detection (AD) methods for network traffic has been intensively investigated by the research community in recent years. However, less attention has been devoted to the issues which eventually arise when deploying such tools in a real operational context. We designed a statistical based change detection algorithm for identifying deviations in distribution time series. The proposed method has been applied to the analysis of a large dataset from an operational 3G mobile network, in the perspective of the adoption of such a tool in production. Our algorithm is designed to cope with the marked non-stationarity and daily/weekly seasonality that characterize the traffic mix in a large public network. Several practical issues emerged during the study, including the need to handle incompleteness of the collected data, the difficulty in drilling down the cause of certain alarms, and the need for human assistance in resetting the algorithm after a persistent change in network configuration (e.g. a capacity upgrade). We report on our practical experience, highlighting the key lessons learned and the hands-on experience gained from such an analysis. Finally, we propose a novel methodology based on semi-synthetic traces for tuning and performance assessment of the proposed AD algorithm. Copyright © 2010 John Wiley & Sons, Ltd. [source]


Distributed Gaussian discrete variable representation

INTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY, Issue 1 2005
Hasan Karabulut
Abstract A discrete variable representation (DVR) made from distributed Gaussians gn(x) = e, (n = ,,, ,, ,) and its infinite grid limit is described. The infinite grid limit of the distributed Gaussian DVR (DGDVR) reduces to the sinc function DVR of Colbert and Miller in the limit c , 0. The numerical performance of both finite and infinite grid DGDVRs and the sinc function DVR is compared. If a small number of quadrature points are taken, the finite grid DGDVR performs much better than both infinite grid DGDVR and sinc function DVR. The infinite grid DVRs lose accuracy due to the truncation error. In contrast, the sinc function DVR is found to be superior to both finite and infinite grid DGDVRs if enough grid points are taken to eliminate the truncation error. In particular, the accuracy of DGDVRs does not get better than some limit when the distance between Gaussians d goes to zero with fixed c, whereas the accuracy of the sinc function DVR improves very quickly as d becomes smaller, and the results are exact in the limit d , 0. An analysis of the performance of distributed basis functions to represent a given function is presented in a recent publication. With this analysis, we explain why the sinc function DVR performs better than the infinite grid DGDVR. The analysis also traces the inability of Gaussians to yield exact results in the limit d , 0 to the incompleteness of this basis in this limit. © 2005 Wiley Periodicals, Inc.

Sampling and concentration values of incomplete bibliographies

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 4 2002
L. Egghe
This article studies concentration aspects of bibliographies. More, in particular, we study the impact of incompleteness of such a bibliography on its concentration values (i.e., its degree of inequality of production of its sources). Incompleteness is modeled by sampling in the complete bibliography. The model is general enough to comprise truncation of a bibliography as well as a systematic sample on sources or items. In all cases we prove that the sampled bibliography (or incomplete one) has a higher concentration value than the complete one. These models, hence, shed some light on the measurement of production inequality in incomplete bibliographies. [source]


Sensitivity analysis for incomplete contingency tables: the Slovenian plebiscite case

JOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES C (APPLIED STATISTICS), Issue 1 2001
Geert Molenberghs
Classical inferential procedures induce conclusions from a set of data to a population of interest, accounting for the imprecision resulting from the stochastic component of the model. Less attention is devoted to the uncertainty arising from (unplanned) incompleteness in the data. Through the choice of an identifiable model for non-ignorable non-response, one narrows the possible data-generating mechanisms to the point where inference only suffers from imprecision. Some proposals have been made for assessing the sensitivity to these modelling assumptions; many are based on fitting several plausible but competing models. For example, we could assume that the missing data are missing at random in one model, and then fit an additional model where non-random missingness is assumed. On the basis of data from a Slovenian plebiscite, conducted in 1991, to prepare for independence, it is shown that such an ad hoc procedure may be misleading. We propose an approach which identifies and incorporates both sources of uncertainty in inference: imprecision due to finite sampling and ignorance due to incompleteness. A simple sensitivity analysis considers a finite set of plausible models. We take this idea one step further by considering more degrees of freedom than the data support. This produces sets of estimates (regions of ignorance) and sets of confidence regions (combined into regions of uncertainty). [source]


What is the largest Einstein radius in the universe?

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 2 2009
Masamune Oguri
ABSTRACT The Einstein radius plays a central role in lens studies as it characterizes the strength of gravitational lensing. In particular, the distribution of Einstein radii near the upper cut-off should probe the probability distribution of the largest mass concentrations in the universe. Adopting a triaxial halo model, we compute expected distributions of large Einstein radii. To assess the cosmic variance, we generate a number of Monte Carlo realizations of all-sky catalogues of massive clusters. We find that the expected largest Einstein radius in the universe is sensitive to parameters characterizing the cosmological model, especially ,8: for a source redshift of unity, they are 42+9,7, 35+8,6 and 54+12,7 arcsec (errors denote 1, cosmic variance), assuming best-fitting cosmological parameters of the Wilkinson Microwave Anisotropy Probe five-year (WMAP5), three-year (WMAP3) and one-year (WMAP1) data, respectively. These values are broadly consistent with current observations given their incompleteness. The mass of the largest lens cluster can be as small as , 1015 M,. For the same source redshift, we expect in all sky ,35 (WMAP5), ,15 (WMAP3) and ,150 (WMAP1) clusters that have Einstein radii larger than 20 arcsec. For a larger source redshift of 7, the largest Einstein radii grow approximately twice as large. Whilst the values of the largest Einstein radii are almost unaffected by the level of the primordial non-Gaussianity currently of interest, the measurement of the abundance of moderately large lens clusters should probe non-Gaussianity competitively with cosmic microwave background experiments, but only if other cosmological parameters are well measured. These semi-analytic predictions are based on a rather simple representation of clusters, and hence calibrating them with N -body simulations will help to improve the accuracy. We also find that these ,superlens' clusters constitute a highly biased population. For instance, a substantial fraction of these superlens clusters have major axes preferentially aligned with the line-of-sight. As a consequence, the projected mass distributions of the clusters are rounder by an ellipticity of ,0.2 and have , 40,60 per cent larger concentrations compared with typical clusters with similar redshifts and masses. We argue that the large concentration measured in A1689 is consistent with our model prediction at the 1.2, level. A combined analysis of several clusters will be needed to see whether or not the observed concentrations conflict with predictions of the flat ,-dominated cold dark matter model. [source]


Observational biases in Lagrangian reconstructions of cosmic velocity fields

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 4 2008
G. Lavaux
ABSTRACT Lagrangian reconstruction of large-scale peculiar velocity fields can be strongly affected by observational biases. We develop a thorough analysis of these systematic effects by relying on specially selected mock catalogues. For the purpose of this paper, we use the Monge,Ampère,Kantorovitch (MAK) reconstruction method, although any other Lagrangian reconstruction method should be sensitive to the same problems. We extensively study the uncertainty in the mass-to-light assignment due to incompleteness (missing luminous mass tracers), and the poorly determined relation between mass and luminosity. The impact of redshift distortion corrections is analysed in the context of MAK and we check the importance of edge and finite-volume effects on the reconstructed velocities. Using three mock catalogues with different average densities, we also study the effect of cosmic variance. In particular, one of them presents the same global features as found in observational catalogues that extend to 80 h,1 Mpc scales. We give recipes, checked using the aforementioned mock catalogues, to handle these particular observational effects, after having introduced them into the mock catalogues so as to quantitatively mimic the most densely sampled currently available galaxy catalogue of the nearby Universe. Once biases have been taken care of, the typical resulting error in reconstructed velocities is typically about a quarter of the overall velocity dispersion, and without significant bias. We finally model our reconstruction errors to propose an improved Bayesian approach to measure ,m in an unbiased way by comparing the reconstructed velocities to the measured ones in distance space, even though they may be plagued by large errors. We show that, in the context of observational data, it is possible to build a nearly unbiased estimator of ,m using MAK reconstruction. [source]


The stellar mass density at z, 6 from Spitzer imaging of i,-drop galaxies

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 3 2007
Laurence P. Eyles
ABSTRACT We measure the ages, stellar masses, and star formation histories of z, 6 galaxies, observed within 1 Gyr of the big bang. We use imaging from the Hubble Space Telescope (HST) and the Spitzer Space Telescope from the public ,Great Observatories Origins Deep Survey' (GOODS), coupled with ground-based near-infrared imaging, to measure their spectral energy distributions (SEDs) from 0.8,5 ,m, spanning the rest-frame ultraviolet (UV) and optical. From our sample of ,50 ,i,-drop' Lyman-break star-forming galaxies in GOODS-South with z,AB < 27, we focus on ,30 with reliable photometric or spectroscopic redshifts. Half of these are confused with foreground sources at Spitzer resolution, but from the 16 with clean photometry we find that a surprisingly large fraction (40 per cent) have evidence for substantial Balmer/4000-Å spectral breaks. This indicates the presence of old underlying stellar populations that dominate the stellar masses. For these objects, we find ages of ,200,700 Myr, implying formation redshifts of 7 ,zf, 18, and large stellar masses in the range ,1,3 × 1010 M,. Analysis of seven i,-drops that are undetected at 3.6 ,m indicates that these are younger, considerably less massive systems. We calculate that emission line contamination should not severely affect our photometry or derived results. Using SED fits out to 8 ,m, we find little evidence for substantial intrinsic dust reddening in our sources. We use our individual galaxy results to obtain an estimate of the global stellar mass density at z, 6. Correcting for incompleteness in our sample, we find the z, 6 comoving stellar mass density to be 2.5 × 106 M, Mpc,3. This is a lower limit, as post-starburst and dust-obscured objects, and also galaxies below our selection thresholds, are not accounted for. From our results, we are able to explore the star formation histories of our selected galaxies, and we suggest that the past global star formation rate may have been much higher than that observed at the z, 6 epoch. The associated UV flux we infer at z > 7 could have played a major role in reionizing the Universe. [source]


The Millennium Galaxy Catalogue: a census of local compact galaxies

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 4 2006
J. Liske
ABSTRACT We use the Millennium Galaxy Catalogue (MGC) to study the effect of compact galaxies on the local field galaxy luminosity function (LF). Here, we observationally define as ,compact' galaxies that are too small to be reliably distinguished from stars using a standard star,galaxy separation technique. In particular, we estimate the fraction of galaxies that are misclassified as stars due to their compactness. We have spectroscopically identified all objects to Bmgc= 20 mag in a 1.14-deg2 subregion of the MGC, regardless of morphology. From these data we develop a model of the high surface brightness (SB) incompleteness and estimate that ,1 per cent of galaxies with Bmgc < 20 mag are misclassified as stars, with an upper limit of 2.3 per cent at 95 per cent confidence. However, since the missing galaxies are preferentially sub- L* their effect on the faint end of the LF is substantially amplified: we find that they contribute ,6 per cent to the total LF in the range ,17 < MB < ,14 mag, which raises the faint end slope , by 0.03+0.02,0.01. Their contribution to the total B -band luminosity density is ,2 per cent. Roughly half of the missing galaxies have already been recovered through spectroscopy of morphologically stellar targets selected mainly by colour. We find that the missing galaxies mostly consist of intrinsically small, blue, star forming, sub- L* objects. In combination with the recent results of Driver et al. we have now demonstrated that the MGC is free from both high- and low-SB selection bias for giant galaxies (MB,,17 mag). Dwarf galaxies, on the other hand, are significantly affected by these selection effects. To gain a complete view of the dwarf population will require both deeper and higher-resolution surveys.

galics, V: Low- and high-order clustering in mock Sloan Digital Sky Surveys

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 3 2006
Jérémy Blaizot
ABSTRACT We use the galics hybrid model of galaxy formation to explore the nature of galaxy clustering in the local Universe. We bring the theoretical predictions of our model into the observational plane using the momaf software to build mock catalogues which mimic Sloan Digital Sky Survey (SDSS) observations. We measure low- and high-order angular clustering statistic from these mock catalogues, after selecting galaxies the same way as for observations, and compare them directly to estimates from the SDSS data. Note that we also present the first measurements of high-order statistics on the SDSS DR1. We find that our model is in general good agreement with observations in the scale/luminosity range where we can trust the predictions. This range is found to be limited (i) by the size of the dark matter simulation used , which introduces finite volume effects at large scales , and by the mass resolution of this simulation , which introduces incompleteness at apparent magnitudes fainter than r, 20. We then focus on the small-scale clustering properties of galaxies and investigate the behaviour of three different prescriptions for positioning galaxies within haloes of dark matter. We show that galaxies are poor tracers of either DM particles or DM substructures, within groups and clusters. Instead, SDSS data tells us that the distribution of galaxies lies somewhat in between these two populations. This confirms the general theoretical expectation from numerical simulations and semi-analytic modelling. [source]


Populating the Galaxy with low-mass X-ray binaries

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 3 2006
Paul D. Kiel
ABSTRACT We perform binary population-synthesis calculations to investigate the incidence of low-mass X-ray binaries (LMXBs) and their birth rate in the Galaxy. We use a binary-evolution algorithm that models all the relevant processes including tidal circularization and synchronization. Parameters in the evolution algorithm that are uncertain and may affect X-ray binary formation are allowed to vary during the investigation. We agree with previous studies that under standard assumptions of binary evolution the formation rate and number of black hole (BH) LMXBs predicted by the model are more than an order of magnitude less than what is indicated by observations. We find that the common-envelope process cannot be manipulated to produce significant numbers of BH LMXBs. However, by simply reducing the mass-loss rate from helium stars adopted in the standard model, to a rate that agrees with the latest data, we produce a good match to the observations. Including LMXBs that evolve from intermediate-mass systems also leads to favourable results. We stress that constraints on the X-ray binary population provided by observations are used here merely as a guide as surveys suffer from incompleteness and much uncertainty is involved in the interpretation of results.

The abundance and radial distribution of satellite galaxies

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 4 2005
Frank C. Van Den Bosch
ABSTRACT Using detailed mock galaxy redshift surveys (MGRSs) we investigate the abundance and radial distribution of satellite galaxies. The mock surveys are constructed using large numerical simulations and the conditional luminosity function (CLF), and are compared against data from the Two Degree Field Galaxy Redshift Survey (2dFGRS). We use Monte Carlo Markov chains to explore the full posterior distribution of the CLF parameter space, and show that the average relation between light and mass is tightly constrained and in excellent agreement with our previous models and with that of Vale & Ostriker. The radial number density distribution of satellite galaxies in the 2dFGRS reveals a pronounced absence of satellites at small projected separations from their host galaxies. This is (at least partly) owing to the overlap and merging of galaxy images in the 2dFGRS parent catalogue. Owing to the resulting close-pair incompleteness we are unfortunately unable to put meaningful constraints on the radial distribution of satellite galaxies; the data are consistent with a radial number density distribution that follows that of the dark matter particles, but we cannot rule out alternatives with a constant number density core. Marginalizing over the full CLF parameter space, we show that in a ,CDM concordance cosmology the observed abundances of host and satellite galaxies in the 2dFGRS indicate a power spectrum normalization of ,8, 0.7. The same cosmology but with ,8= 0.9 is unable to match simultaneously the abundances of host and satellite galaxies. This confirms our previous conclusions based on the pairwise peculiar velocity dispersions and the group multiplicity function. [source]


Lyman break galaxies and the star formation rate of the Universe at z, 6

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 2 2003
Elizabeth R. Stanway
ABSTRACT We determine the space density of UV-luminous starburst galaxies at z, 6 using deep HST ACS SDSS- i, (F775W) and SDSS- z, (F850LP) and VLT ISAAC J and Ks band imaging of the Chandra Deep Field South. We find eight galaxies and one star with (i,,z,) > 1.5 to a depth of z,AB= 25.6 (an 8, detection in each of the 3 available ACS epochs). This corresponds to an unobscured star formation rate of ,15 h,270 M, yr,1 at z= 5.9, equivalent to L* for the Lyman-break population at z= 3,4 (,,= 0.7, ,M= 0.3). We are sensitive to star-forming galaxies at 5.6 ,z, 7.0 with an effective comoving volume of ,1.8 × 105h,370 Mpc3 after accounting for incompleteness at the higher redshifts due to luminosity bias. This volume should encompass the primeval subgalactic-scale fragments of the progenitors of about a thousand L* galaxies at the current epoch. We determine a volume-averaged global star formation rate of (6.7 ± 2.7) × 10,4h70 M, yr,1 Mpc,3 at z, 6 from rest-frame UV selected starbursts at the bright end of the luminosity function: this is a lower limit because of dust obscuration and galaxies below our sensitivity limit. This measurement shows that at z, 6 the star formation density at the bright end is a factor of ,6 times less than that determined by Steidel et al. for a comparable sample of UV-selected galaxies at z= 3,4, and so extends our knowledge of the star formation history of the Universe to earlier times than previous work and into the epoch where reionization may have occurred.

On the kinematic deconvolution of the local neighbourhood luminosity function

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 1 2002
C. Pichon
A method for inverting the statistical star counts equation, including proper motions, is presented; in order to break the degeneracy in that equation, it uses the supplementary constraints required by dynamical consistency. The inversion gives access to both the kinematics and the luminosity function of each population in three régimes: the singular ellipsoid, the constant ratio Schwarzschild ellipsoid plane-parallel models and the epicyclic model. This more realistic model is tailored to account for the local neighbourhood density and velocity distribution. The first model is fully investigated, both analytically and by means of a non-parametric inversion technique, while the second model is shown to be formally its equivalent. The effect of noise and incompleteness in apparent magnitude is investigated. The third model is investigated by a non-parametric inversion technique where positivity of the underlying luminosity function is explicitly accounted for. It is argued that its future application to data such as the Tycho catalogue (and in the upcoming satellite GAIA) could lead , provided that the vertical potential and or the asymmetric drift or w, are known , to a non-parametric determination of the local neighbourhood luminosity function without any reference to stellar evolution tracks. It should also yield the proportion of stars for each kinematic component and a kinematic diagnostic to split the thin disc from the thick disc or the halo. [source]


The ROSAT Brightest Cluster Sample , IV.

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 2 2000
The extended sample
We present a low-flux extension of the X-ray-selected ROSAT Brightest Cluster Sample (BCS) published in Paper I of this series. Like the original BCS and employing an identical selection procedure, the BCS extension is compiled from ROSAT All-Sky Survey (RASS) data in the northern hemisphere (,,0°) and at high Galactic latitudes (|b|,20°). It comprises 99 X-ray-selected clusters of galaxies with measured redshifts z,0.3 (as well as eight more at z>0.3) and total fluxes between 2.8×10,12 and 4.4×10,12 erg cm,2 s,1 in the 0.1,2.4 keV band (the latter value being the flux limit of the original BCS). The extension can be combined with the main sample published in 1998 to form the homogeneously selected extended BCS (eBCS), the largest and statistically best understood cluster sample to emerge from the RASS to date. The nominal completeness of the combined sample (defined with respect to a power-law fit to the bright end of the BCS log N,log S distribution) is relatively low at 75 per cent (compared with 90 per cent for the high-flux sample of Paper I). However, just as for the original BCS, this incompleteness can be accurately quantified, and thus statistically corrected for, as a function of X-ray luminosity and redshift. In addition to its importance for improved statistical studies of the properties of clusters in the local Universe, the low-flux extension of the BCS is also intended to serve as a finding list for X-ray-bright clusters in the northern hemisphere which we hope will prove useful in the preparation of cluster observations with the next generation of X-ray telescopes such as Chandra and XMM-Newton.

The ,,M relationship in pre-main sequence stars

MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY: LETTERS (ELECTRONIC), Issue 1 2006
C. J. Clarke
ABSTRACT We examine the recent data and analysis of Natta et al. concerning the accretion rate on to young stars as a function of stellar mass, and conclude that the apparently steep dependence of accretion rate on mass is strongly driven by selection/detection thresholds. We argue that a convincing demonstration of a physical relationship between accretion and stellar mass requires further studies which, as is the case for Natta et al., include information on upper limits, and which quantify the possible incompleteness of the sample, at both low and high accretion rates. We point out that the distribution of detections in the -plane can in principle be used to test conventional accretion disc evolutionary models, and that higher sensitivity observations might be able to test the hypothesis of accelerated disc clearing at late times.

A quantitative approach to benefit-risk assessment of medicines , part 1: the development of a new model using multi-criteria decision analysis,

PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue S1 2007
Filip Mussen PhD
Abstract Purpose One of the most important uses of benefit-risk assessment pertains to approval of new medicines by regulatory authorities and the subsequent review of these products during their life-cycle when new safety and/or efficacy data becomes available. At present, there exist no validated, well-accepted models for benefit-risk assessment that have the appropriate degree of sophistication, and as a consequence no models are widely used by regulatory authorities or industry. The aim of the study was therefore to develop a new model for benefit-risk assessment of medicines using multi-criteria decision analysis (MCDA). Methods The MCDA methodology was used for a systematic approach to assess the benefit risk ratio of medicines. The reasons for adopting this approach were (1) taking multiple benefit and risk criteria into account, (2) making a judgement on the evidence and potential uncertainty because of the incompleteness of evidence, and (3) making trade-offs of the benefits against risks. Results It was demonstrated through a seven-step approach how MCDA is used to construct the model. Ten benefit and ten risk criteria were identified to form a value tree. Then fixed scales were established for all criteria and options on the criteria were scored. Weights were assigned for each criteria using swing-weighting. Finally sensitivity analysis was carried. Conclusions This novel approach based on MCDA has the potential for being applied as a new tool for judging and deciding on the benefits and risks, thereby helping regulators and industry in the development and approval of new medicines and their adequate use.

Structure, Agency and Power in Political Analysis: Beyond Contextualised Self-Interpretations

POLITICAL STUDIES REVIEW, Issue 2 2008
Jason Glynos
This article evaluates Mark Bevir and Rod Rhodes' interpretive approach to political analysis by examining their account of social change. Their work is significant because they have endeavoured to construct a distinctive approach which strikes a productive balance between philosophical reflection and analytical attention to the empirical domain. Moreover, in elaborating their approach, Bevir and Rhodes wage a war along a number of fronts: positivism, institutionalism and post-structuralism, and so an analysis of their work enables us to take stock of a range of contemporary methods and approaches. In considering their underlying presuppositions and commitments, we pay particular attention to their account of human agency and its relationship to social structures and political power. While we agree with much of their critique of positivism, naturalism, realism and institutionalism, we argue that Bevir and Rhodes risk overplaying the role of interpreting the individual beliefs and desires of relevant actors to the detriment of a wider net of social practices and logics. Moreover, in challenging their understanding of the post-structuralist approach to political analysis we develop its resources to enrich the possibilities of a critical interpretivism, moving beyond concepts like tradition, dilemma and situated agency. Put more precisely, we argue that the radical contingency of social structures and human agency , their structural incompleteness , discloses new ways of understanding both their character and their mutual intertwining. For example, we develop the categories of lack, dislocation and political identification to think human agency and its relation to wider social structures. More broadly, we argue that an approach developed around different sorts of logics , social, political and fantasmatic , goes some way to steering a different course between a pure thick descriptivism that focuses principally on individual beliefs and desires on the one hand, and a concern with causal laws and mechanisms on the other.

Proceedings of the 20th Annual Conference of the Japanese Association for Adolescent Psychotherapy, 16 November 2002, Tokyo, Japan

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 5 2003
Article first published online: 28 AUG 200
Inpatient treatment of obsessive,compulsive disorder in a child and adolescent psychiatry ward M. USAMI National Center of Neurology and Psychiatry, Kohnodai Hospital, Chiba, Japan This is a case report of a 13-year-old-boy (2nd grade in junior high school). His father had poor communication; his mother was a very fragile woman. The boy had been overprotected by his parents, as long as he responded to their expectations. He did not have any other siblings. He played well with his friends since he was young, and did not have problems until the 1st term (from April to July) of 1st grade in junior high school. However, in September he started to have difficulties going well with his friends, and going to school. He spent most of his time in his room, and began to repeat checking and hand-washing frequently. Even at midnight, he forced his mother to touch the shutter from outside of the house for many times. He also ritually repeated to touch his mother's body, after he licked his hands, for over an hour. He became violent, when his parents tried to stop him. In April, year X, his parents visited our hospital for the first time. From then, his mother could not tolerate her son's coerciveness any longer. His father explained to the boy that ,your mother has been hospitalized', and she started to live in the next room to the boy's without making any noise. After 3 months he noticed that his mother was not hospitalized, and he got very excited. He was admitted to our hospital with his family and relatives, in October, year X. At the initial stage of hospitalization he showed distrust and doubt towards the therapist and hospital. He had little communication with other boys and did not express his feelings. Therefore, there was a period of time where he seemed to wonder whether he could trust the treatment staff or not. During his interviews with his therapist he repeated only ,I'm okay' and did not show much emotional communication. For the boy, exposing himself was equivalent to showing his vulnerability and incompleteness. Therefore, the therapist considered that he was trying to denying his feelings to avoid this. The therapist set goals for considering his own feelings positively and expressing them appropriately. Also, the therapist carried out behavioral restrictions towards him. He hardly had any emotional communication with the staff, and his peer relationship in the ward was superficial. Therefore, he gradually had difficulty spending his time at the end of December On the following day in which he and the therapist decided to return to his house for the first time, he went out of the ward a few days before without permission. From thereon it was possible for him to share feelings such as hostility and aggression, dependence and kindness with the therapist. The therapist changed his role from an invasive one to a more protective one. Then, his unsociability gradually faded. He also developed good peer relationships with other boys in the ward and began to express himself feeling appropriately. He was also able to establish appropriate relations with his parents at home, and friends of his neighborhood began to have normal peer relationships again. During childhood and adolescence, boys with obsessive,compulsive disorder are known to have features such as poor insight and often involving their mothers. We would like to present this case, through our understanding of dynamic psychiatry throughout his hospitalization, and also on the other therapies that were performed. Psychotherapy with a graduate student that discontinued after only three sessions: Was it enough for this client? N. KATSUKI Sophia University, Tokyo, Japan Introduction: Before and after the psychotherapy, SWT was administrated in this case. Comparing these two drawings, the therapist was provided with some ideas of what kind of internal change had taken place inside this client. Referring to the changes observed, we would like to review the purposes and the ways of the psychotherapy, as well as the adequacy of the limited number of the sessions (vis-a-vis result attained.) Also we will discuss later if any other effective ways could be available within the capacities of the consulting system/the clinic in the university. Case: Ms. S Age 24 years. Problems/appeal: (i) awkwardness in the relationship with the laboratory colleagues; (ii) symptoms of sweating, vomiting and quivering; and (iii) anxiety regarding continuing study and job hunting. Diagnosis: > c/o PTSD. Psychotherapeutic setting: At the therapy room in the clinic, placed at the university, 50 min-session; once a week; paralleled with the medical treatment. Process: (1) Since she was expelled from the study team in the previous year, it has become extremely difficult for her to attend the laboratory (lab) due to the aforementioned symptoms. She had a feeling of being neglected by the others. When the therapist suggested that she compose her mental confusions in the past by attending the therapy room, she seemed to be looking forward to it, although she said that she could remember only a few. (2) She reported that she overdosed on sedatives, as she could not stop irritating. She was getting tough with her family, also she slashed the mattress of her bed with a knife for many times. She complained that people neither understood nor appreciated her properly. and she said that she wanted revenge on the leader of the lab by punishing him one way or other. (3) Looking back the previous session, she said ,I had been mentally mixed up at that time, but I feel that now I can handle myself, as I stopped the medication after consulting the psychiatrist. According to what she said, when she disclosed the occurrences in the lab to her mother, she felt to be understood properly by her mother and felt so relieved. and she also reported that she had been sewing up the mattress which she slashed before, without any reason. She added, " although I don't even know what it means, I feel that this work is so meaningful to me, somehow". Finally, she told that she had already made her mind to cope with the situation by herself from now on, although it might result in a flinch from the real solution. Situations being the above, the session was closed. Swt: By the remarkable changes observed between the two drawings, the meanings of this psychotherapy and its closure to the client would be contemplated. Question of how school counselors should deal with separation attendant on students' graduation: On a case in which the separation was not worked through C. ASAHARA Sophia University, Tokyo, Japan Although time limited relationship is one of the important characteristics in school counseling, the question of separation attendant on it has not been much discussed based on specific cases. This study focuses on the question of separation through looking at a particular case, in which the separation was not worked through, and halfway relationship continued even after the student's graduation and the counselor's resignation. I was a part time school counselor at a junior high school in Tokyo. The client was a 14-year-old female student, who could not go to her classroom, and spent a few hours in a sick bay when she came to school. She was in the final grade and there was only half a year left before graduation when we first met, and we started to see each other within a very loose structure. As her personality was hyper-vigilant and defensive, it took almost 2 months before I could feel that she was nearer. Her graduation was the first occasion of separation. On that occasion, I found that there had been a discrepancy between our expectations; while I took it for granted that our relationship would end with the graduation, she expected to see me even after she graduated, and she actually came up to see me once in a while during the next year. A year later, we faced another occasion of separation, that was my resignation. Although I worried about her, all I have done for her was to hand a leaflet of a counseling office, where I work as a part time counselor. Again I could not refer to her feelings or show any concrete directions such as making a fixed arrangement. After an occasional correspondence for the next 10 months (about 2 years after her graduation), she contacted me at the counseling office asking for a constant counseling. Why could I not deal with both occasions? and how did that affect the client thereafter? There were two occasions of separation. At the time of the client's graduation, I seemed to be enmeshed in the way of separation that is peculiar to the school setting. In general in therapeutic relationship, mourning work between counselor and client is regarded as being quite important. At school, however, separation attendant on graduation is usually taken for granted and mourning work for any personal relationship tends to be neglected. Graduation ceremony is a big event but it is not about mourning over one's personal relationships but separation from school. That may be why I did not appreciate how the client counted on our relationship. At the time of my resignation I was too worried about working through a change from very loose structure which is peculiar to the school setting to a usual therapeutic structure (fees are charged, and time, place are fixed). That is why I did nothing but give her a leaflet. In this way, we never talked about her complex feelings such as sadness or loneliness, which she was supposed to experience on separation. Looking at the aforementioned process from the client's viewpoint, it can be easily imagined that she could not accept the fact of separation just because she graduated. and later, she was forced to be in double-bind situation, in which she was accepted superficially (handed a leaflet), while no concrete possibility was proposed concerning our relationship (she could never see me unless she tries to contact me.) As a result, she was left alone and at a loss whether she could count on me or not. The halfway situation or her suspense was reflected in her letter, in which she appeared to be just chatting at first sight, but between the lines there was something more implying her sufferings. Above discussion suggests that in some case, we should not neglect the mourning work even in a school setting. To whom or how it is done is the next theme we should explore and discuss in the future. For now, we should at least be conscious about the question of separation in school setting. Study of the process of psychotherapy with intervals for months M. TERASHIMA Bunkyo Gakuin University, Tokyo, Japan This is a report on the process of psychotherapy of an adolescent girl who showed manic and depressive state. At the time of a depressed state, she could not go to a college and withdrew into home, and the severe regressive situation was shown. Her therapy began at the age of 20 and she wanted to know what her problem was. The process of treatment went on for 4 years but she stopped coming to sessions for several months because of failure of the therapist. She repeated the same thing twice. After going through these intervals the client began to remember and started to talk about her childhood , suffering abusive force from her father, with vivid impressions. They once were hard for her to accept, but she began to establish the consistent figure of herself from past to present. In this case, it could be thought that the intervals of the sessions had a certain role, with which the client controlled the structure of treatment, instead of an attack against the therapist. Her object relation, which is going to control an object offensively, was reflected in these phenomena. That is, it can be said that the ambivalence about dependency , difficult to depend but desirous of the object , was expressed. Discontinuation of the sessions was the product of the compromise formation brought about the ambivalence of the client, and while continuing to receive this ambivalence in the treatment, the client started to realize discontinuance of her memories and then advanced integration of her self-image. For the young client with conflict to dependence such as her, an interval does not destroy the process of treatment but in some cases it could be considered as a therapeutic element. In the intervals the client could assimilate the matter by herself, that acquired by the sessions. Psychotherapy for a schizoid woman who presented eccentric speech and behaviour M. OGASAWARA Osaka University Graduate School of Medicine, Osaka, Japan Case presentation: A case of a 27-year-old woman at the beginning of therapy. Life history: She had been having a wish for death since she was in kindergarten and she had been feeling strong resistance to do the same as others after school attendance. She had a history of ablutomania from the age of 10,15, but the symptom disappeared naturally. and she said that she had been eliminated from groups that she tried to enter. After graduating a junior college, she changed jobs several times without getting a full-time position. Present history: Scolded by her boy friend for her coming home too late one day, she showed confusion such as excitement, self-injury or terror. She consulted a psychiatrist in a certain general hospital, but she presented there eccentric behaviours such as tense facial expression, stiffness of her whole body, or involuntary movement of limbs. and because she felt on bad terms with the psychiatrist and she had come to cause convulsion attacks in the examination room, she was introduced to our hospital. Every session of this psychotherapy was held once a week and for approximately 60 min at a time. Treatment process: She sometimes presented various eccentric attitudes, for example overturning to the floor with screaming (1), going down on her knees when entrance at the door (5), entering with a knife in her mouth and hitting the wall suddenly (7), stiffening herself just outside the door without entering the examination room (9), taking out a knife abruptly and putting it on her neck (40), exclaiming with convulsion responding to every talk from the therapist (41), or stiffening her face and biting herself in the right forearm suddenly (52). She also repeated self-injuries or convulsion attacks outside of the examination room in the early period of the therapy. Throughout the therapy she showed hypersensitivity for interpersonal relations, anxiety about dependence, terror for self-assertion, and avoidance for confrontation to her emotional problems. Two years and 6 months have passed since the beginning of this therapy. She ceased self-injury approximately 1 year and 6 months before and her sense of obscure terror has been gradually reduced to some extent. Discussion: Her non-verbal wariness and aggression to the therapist made the sessions full of tension and the therapist felt a sense of heaviness every time. In contrast, she could not express aggression verbally to the therapist, and when the therapist tried to identify her aggression she denied it. Her anxiety, that she will be thoroughly counterattacked to self-disintegration if she shows aggression to other persons, seems to be so immeasurably strong that she is compelled to deny her own aggression. Interpretations and confrontations by the therapist make her protective, and occasionally she shows stronger resistance in the shape of denial of her problems or conversion symptoms (astasia, aphonia, or involuntary movements) but she never expresses verbal aggression to the therapist. and the therapist feels much difficulty to share sympathy with her, and she expresses distrust against sympathetic approach of the therapist. However, her obvious disturbance that she expresses when she feels the therapist is not sympathetic shows her desire for sympathy. Thus, because she has both strong distrust and desire for sympathy, she is in a porcupine dilemma, which is characteristic of schizoid patients as to whether to lengthen or to shorten the distance between herself and the therapist. This attitude seems to have been derived from experience she might have had during her babyhood and childhood that she felt terror to be counterattacked and deserted when she showed irritation to her mother. In fact, existence of severe problems of the relationship between herself and her mother in her babyhood and childhood can be guessed from her statement. Although she has been repeating experiences to be excluded from other people, she shows no attitude to construct interpersonal relationship actively. On the contrary, by regarding herself to be a victim or devaluating other persons she externalizes responsibility that she herself should assume essentially. The reason must be that her disintegration anxiety is evoked if she recognizes that she herself has problems; that is, that negative things exist inside of her. Therefore, she seems to be inhibited to get depressive position and obliged to remain mainly in a paranoid,schizoid position. As for the pathological level, she seems to have borderline personality organization because of frequent use of mechanisms to externalize fantastically her inner responsibility. For her high ability to avoid confronting her emotional problems making the most of her verbal ability, every intervention of the therapist is invalidated. So, it seems very difficult for her to recognize her own problems through verbal interpretations or confrontation by the therapist, for the present. In general, it is impossible to confront self problems without containing negative emotions inside of the self, but her ability seemed to be insufficient. So, to point out her problems is considered to be very likely to result in her confusion caused by persecution anxiety. Although the therapy may attain the stage on which verbal interpretation and confrontation work better some day, the therapist is compelled to aim at promoting her ability to hold negative emotion inside of herself for the time being. For the purpose, the therapist is required to endure the situation in which she brings emotion that makes the therapist feel negative counter-transference and her process to experience that the therapeutic relation itself would not collapse by holding negative emotion. On supportive psychotherapy with a male adolescent Y. TERASHIMA Kitasato University Health Care Center, Kanagawa, Japan Adolescent cases sometimes show dramatic improvements as a consequence of psychotherapy. The author describes how psychotherapy can support an adolescent and how theraputic achievements can be made. Two and a half years of treatment sessions with a male adolescent patient are presented. The patient was a 19-year-old man, living with his family. He had 5 years of experience living abroad with his family and he was a preparatory school student when he came to a mental clinic for help. He was suffering from not being able to sleep well, from difficulties concerning keeping his attention on one thing, and from fear of going to distant places. He could barely leave his room, and imagined the consequence of overdosing or jumping out of a window. He claimed that his life was doomed because his family moved from a town that was familiar to him. At the first phase of psychotherapy that lasted for approximately 1 year, the patient seldom responded to the therapist. The patient was basically silent. He told the therapist that the town he lives in now feels cold or that he wants to become a writer. However, these comments were made without any kind of explanation and the therapist felt it very difficult to understand what the patient was trying to say. The sessions continued on a regular basis. However, the therapist felt very useless and fatigued. Problems with the patient and his family were also present at this phase of psychotherapy. He felt unpleasant at home and felt it was useless to expect anything from his parents. These feelings were naturally transferred to the therapist and were interpreted. However, interpretation seemed to make no changes in the forms of the patient's transference. The second phase of psychotherapy began suddenly. The patient kept saying that he did not know what to talk about. However, after a brief comment made by the therapist on the author of the book he was reading, the patient told the therapist that it was unexpected that the therapist knew anything of his favorite writer. After this almost first interaction between the patient and the therapist, the patient started to show dramatic changes. The patient started to bring his favorite rock CDs to sessions where they were played and the patient and the therapist both made comments on how they felt about the music. He also started asking questions concerning the therapist. It seemed that the patient finally started to want to know the therapist. He started communicating. The patient was sometimes silent but that did not last long. The therapist no longer felt so useless and emotional interaction, which never took place in the first phase, now became dominant. The third phase happened rapidly and lasted for approximately 10 months. Conversations on music, art, literature and movies were made possible and the therapist seldom felt difficulties on following the patient's line of thought. He started to go to schools and it was difficult at first but he started adjusting to the environment of his new part-time jobs. By the end of the school year, he was qualified for the entrance to a prestigious university. The patient's problems had vanished except for some sleeping difficulties, and he did not wish to continue the psychotherapy sessions. The therapist's departure from the clinic added to this and the therapy was terminated. The patient at first reminded the therapist of severe psychological disturbances but the patient showed remarkable progress. Three points can be considered to have played important roles in the therapy presented. The first and the most important is the interpretation by behavior. The patient showed strong parental transference to the therapist and this led the therapist to feel useless and to feel fatigue. Content analysis and here-and-now analysis seemed to have played only a small part in the therapy. However, the therapist tried to keep in contact with the patient, although not so elegant, but tried to show that the therapist may not be useless. This was done by maintaining the framework of the therapy and by consulting the parents when it was considered necessary. Second point is the role that the therapist intentionally took as a model or target of introjection. With the help of behavioral interpretation that showed the therapist and others that it may not be useless, the patient started to introject what seemed to be useful to his well being. It can be considered that this role took some part in the patient going out and to adjust to the new environment. Last, fortune of mach must be considered. The patient and the therapist had much in common. It was very fortunate that the therapist knew anything about the patient's favorite writer. The therapist had some experience abroad when he was young. Although it is a matter of luck that the two had things in common, it can be said that the congeniality between the patient and the therapist played an important role in the successful termination of the therapy. From the physical complaint to the verbal appeal of A's recovery process to regain her self-confidence C. ITOKAWA and S. KAZUKAWA Toyama Mental Health Center, Toyama, Japan This is one of the cases at Toyama Mental Health Center about a client here, we will henceforth refer to her simply as ,A'. A was a second grade high school student. We worked with her until her high school graduation using our center's full functions; counseling, medical examination and the course for autogenic training (AT). She started her counseling by telling us that the reason for her frequent absences from school began because of stomach pains when she was under a lot of stress for 2 years of junior high school, from 2nd grade to 3rd grade. Due to a lack of self confidence and a constant fear of the people around her, she was unable to use the transportation. She would spend a large amount of time at the school infirmary because she suffered from self-diagnosed hypochondriac symptoms such as nausea, diarrhea and a palpitation. She continued that she might not be able to have the self-confidence to sit still to consult me on her feelings in one of our sessions. A therapist advised her to take the psychiatric examination and the use of AT and she actually saw the medical doctor. In counseling (sessions), she eventually started to talk about the abuse that started just after her entering of junior high school; she approached the school nurse but was unable to tell her own parents because she did not trust them. In doing so, she lost the rest of her confidence, affecting the way she looked at herself and thought of how others did. At school she behaved cheerfully and teachers often accused her of idleness as they regarded this girl's absences along with her brightly dyed hair and heavy make-up as her negligent laziness. I, as her therapist, contacted some of the school's staff and let them know of her situation in detail. As the scolding from the teachers decreased, we recognized the improvement of her situation. In order to recover from the missed academic exposure due to her long absence, she started to study by herself. In a couple of months her physical condition improved gradually, saying ,These days I have been doing well by myself, haven't I?' and one year later, her improved mental condition enabled her to go up to Tokyo for a concert and furthermore even to enjoy a short part-time job. She continued the session and the medical examination dually (in tangent) including the consultation about disbelief to the teachers, grade promotion, relationships between friends and physical conditions. Her story concentrated on the fact that she had not grown up with sufficiently warm and compassionate treatment and she could not gain any mental refuge in neither her family nor her school, or even her friends. Her prospects for the future had changed from the short-ranged one with no difficulty to the ambitious challenge: she aimed to try for her favorite major and hoped to go out of her prefecture. But she almost had to give up her own plan because the school forced her to change her course as they recommended. (because of the school's opposition with her own choice). So without the trust of the teachers combined with her low self-esteem she almost gave up her hopes and with them her forward momentum. In this situation as the therapist, I showed her great compassion and discussed the anger towards the school authorities, while encouraging this girl by persuading her that she should have enough self-confidence by herself. Through such sessions, she was sure that if she continued studying to improve her own academic ability by herself she could recognize the true meaning of striving forward. and eventually, she received her parents' support who had seemed to be indifferent to her. At last she could pass the university's entrance exams for the school that she had yearned to attend. That girl ,A' visited our center 1 month later to show us her vivid face. I saw a bright smile on her face. It was shining so brightly. [source]


Is Central Asia the eastern outpost of the Neandertal range?

AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2009
A reassessment of the Teshik-Tash child
Abstract Since its discovery in southeastern Uzbekistan in 1938, the Teshik-Tash child has been considered a Neandertal. Its affinity is important to studies of Late Pleistocene hominin growth and development as well as interpretations of the Central Asian Middle Paleolithic and the geographic distribution of Neandertals. A close examination of the original Russian monograph reveals the incompleteness of key morphologies associated with the cranial base and face and problems with the reconstruction of the Teshik-Tash cranium, making its Neandertal attribution less certain than previously assumed. This study reassesses the Neandertal status of Teshik-Tash 1 by comparing it to a sample of Neandertal, Middle and Upper Paleolithic modern humans, and recent human sub-adults. Separate examinations of the cranium and mandible are conducted using multinomial logistic regression and discriminant function analysis to assess group membership. Results of the cranial analysis group Teshik-Tash with Upper Paleolithic modern humans when variables are not size-standardized, while results of the mandibular analysis place the specimen with recent modern humans for both raw and size-standardized data. Although these results are influenced by limitations related to the incomplete nature of the comparative sample, they suggest that the morphology of Teshik-Tash 1 as expressed in craniometrics is equivocal. Although, further quantitative studies as well as additional sub-adult fossil finds from this region are needed to ascertain the morphological pattern of this specimen specifically, and Central Asian Middle Paleolithic hominins in general, these results challenge current characterizations of this territory as the eastern boundary of the Neandertal range during the Late Pleistocene.

The cosmopolitan imagination: critical cosmopolitanism and social theory

THE BRITISH JOURNAL OF SOCIOLOGY, Issue 1 2006
Gerard Delanty
Abstract Critical cosmopolitanism is an emerging direction in social theory and reflects both an object of study and a distinctive methodological approach to the social world. It differs from normative political and moral accounts of cosmopolitanism as world polity or universalistic culture in its conception of cosmopolitanism as socially situated and as part of the self-constituting nature of the social world itself. It is an approach that shifts the emphasis to internal developmental processes within the social world rather than seeing globalization as the primary mechanism. This signals a post-universalistic kind of cosmopolitanism, which is not merely a condition of diversity but is articulated in cultural models of world openness through which societies undergo transformation. The cosmopolitan imagination is articulated in framing processes and cultural models by which the social world is constituted; it is therefore not reducible to concrete identities, but should be understood as a form of cultural contestation in which the logic of translation plays a central role. The cosmopolitan imagination can arise in any kind of society and at any time but it is integral to modernity, in so far as this is a condition of self-problematization, incompleteness and the awareness that certainty can never be established once and for all. As a methodologically grounded approach, critical cosmopolitan sociology has a very specific task: to discern or make sense of social transformation by identifying new or emergent social realities.
