[source] TAYLORING REFORMED EPISTEMOLOGY: CHARLES TAYLOR, ALVIN PLANTINGA AND THE DE JURE CHALLENGE TO CHRISTIAN BELIEF by Deane-Peter Baker THEOLOGY, PSYCHOANALYSIS AND TRAUMA by Marcus PoundNEW BLACKFRIARS, Issue 1024 2008GRAEME RICHARDSON First page of article [source] Brand Name Audit Pricing, Industry Specialization, and Leadership Premiums post-Big 8 and Big 6 Mergers,CONTEMPORARY ACCOUNTING RESEARCH, Issue 1 2002Andrew Ferguson Abstract This paper investigates brand name, industry specialization, and leadership audit pricing in the wake of the mergers that created the Big 6 and the Big 5 accounting firms. For samples of Australian listed public companies in each of the postmerger years 1990, 1992, 1994, and 1998, we estimate national audit fee premiums for the Big 6/5 auditors and the industry specialists and leaders. We find limited support for the ability of the Big 6/5 to obtain fee premiums over non-Big 6/5 for those industries not having specialist auditors. Nonspecialist Big 6/5 auditors are able to obtain fee premiums over nonspecialist non-Big 6/5 auditors for those industries having specialist auditors. However, this result only holds among the smaller half of our sample. We do not find strong support for the presence of industry specialist premiums in the postmerger years, especially after 1990, using various definitions of industry specialist. We find, at best, limited support for the presence of industry leadership premiums. The evidence suggests that after the Big 8/6 audit firm mergers, some caution is required in generalizing the Craswell, Francis, and Taylor 1995 finding of national market industry specialist premiums. More generally, the study raises questions about the tenuous link between the concept of specialization and national market-share statistics. [source] The Illness/Injury Sensitivity Index: an examination of construct validityDEPRESSION AND ANXIETY, Issue 6 2006R. Nicholas Carleton M.A. Abstract The 11-item Illness/Injury Sensitivity Index [ISI; Taylor, 1993: J Behav Ther Exp Psychiatry 24:289,299] measures fears of injury and illness and has the potential to delineate some mechanisms underlying anxiety-associated chronic health conditions. In a principal components analysis in 2005, Carleton et al. [2005a: J Psychopathol Behav Assess 27:235,241] indicated that a two-factor solution (Fear of Injury and Fear of Illness) best explained the structure of the ISI. The primary purpose of this study was to examine the structural and construct validity of the ISI. Results supported a two-factor solution after removal of two overinclusive items. Although the measure demonstrated good factorial validity, convergent and discriminant validity require further evaluation. In addition, a substantial correlation with fear of pain suggests a shift in our perspective on what constitutes a fundamental fear. Future research implications are discussed.

[source] Locating Responsibility: The Sphere Humanitarian Charter and Its RationaleDISASTERS, Issue 2 2004James Darcy Criticised by some as a technical initiative that neglects core principles, Sphere was seen by its originators precisely as an articulation of principle. The Humanitarian Charter was the main vehicle through which this was expressed, but its relationship to the Minimum Standards has remained a matter of uncertainty. Specifically, it was unclear in the original (1999) edition of Sphere how the concept of rights informed the Minimum Standards. The revised (2004) edition goes some way to clarifying this in the way the standards are framed, yet the link between the standards and the charter remains unclear. The concern with the quality and accountability of humanitarian assistance, which motivated the attempt to establish system-wide standards through the Sphere Project, was accompanied by a desire to establish such actions in a wider framework of legal and political responsibility. In part, this reflects the conditional nature of the undertaking that agencies make when they adopt Sphere. This aspect of the charter has been neglected, but it is fundamental to an understanding of the standards and their application. This paper considers the rationale of the Sphere Humanitarian Charter and the conceptual model that underpins it. It discusses the relationship between the charter and the Minimum Standards, and the sense in which the latter are properly called ,rights-based' (explored further in a related paper herein by Young and Taylor). The author was closely involved in the conception and drafting of the charter, and this paper attempts to convey some of the thinking that lay behind it. [source] What does Monetary Policy Reveal about a Central Bank's Preferences?ECONOMIC NOTES, Issue 3 2003Efrem Castelnuovo The design of monetary policy depends on the targeting strategy adopted by the central bank. This strategy describes a set of policy preferences, which are actually the structural parameters to analyse monetary policy making. Accordingly, we develop a calibration method to estimate a central bank's preferences from the estimates of an optimal Taylor,type rule. The empirical analysis on US data shows that output stabilization has not been an independent argument in the Fed's objective function during the Greenspan's era. This suggests that the output gap has entered the policy rule only as leading indicator for future inflation, therefore being only instrumental (to stabilize inflation) rather than important per se. (J.E.L.: C61, E52, E58). [source] First record of Blastopsylla occidentalis Taylor, 1985 (Hemiptera: Psyllidae), a Eucalyptus psyllid in Cameroon, Central AfricaENTOMOLOGICAL RESEARCH, Issue 4 2010Joseph Lebel TAMESSE Abstract In order to investigate the biodiversity of psyllids in Cameroon, we collected a psyllid on Eucalyptus spp. (Myrtaceae) for the first time. Morphometric and morphological studies of this psyllid enable us to identify it as Blastopsylla occidentalis Taylor (Hemiptera: Psylloidea). Blastopsylla occidentalis lives on four Eucalyptus species (Eucalyptus globulus, E. saligna, E. deglupta, E. camaldulensis) in the Western and Central regions of the country. A description and illustration of the different developmental stages of B. occidentalis will allow the identification of this pest of Eucalyptus. [source] The cytosolic domain of APP induces the relocalization of dynamin 3 in hippocampal neuronsEUROPEAN JOURNAL OF NEUROSCIENCE, Issue 9 2006X. Meckler Abstract Amyloid precursor protein (APP) has been the subject of intense research to uncover its implication in Alzheimer's disease. Its physiological function is, however, still poorly understood. Herein, we investigated its possible influence on the development of cultured hippocampal neurons. A peptide corresponding to the APP intracellular domain linked to a cell-penetrating peptide was used to alter the interactions of APP with its cytosolic partners. This treatment promoted the concentration of the cytosolic GTPase dynamin 3 (Dyn3) in neurite segments when most untreated cells displayed a homogenous punctate distribution of Dyn3. The Dyn3-labelled segments were excluded from those revealed by APP staining after aldehyde fixation. Interestingly, after aldehyde fixation MAP2 also labelled segments excluded from APP-stained segments. Thus APP is also a marker for the spacing pattern of neurites demonstrated by Taylor & Fallon (2006)J. Neurosci., 26, 1154,4463. [source] Manipulating subcategory salience: exploring the link between skin tone and social perception of BlacksEUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 5 2004Keith B. Maddox Guided by the model of social category salience proposed by M. Blanz (1999), the present paper explores factors affecting the salience of skin tone-based subcategories among Blacks in the United States. Adapting the group discussion paradigm developed by S.E. Taylor and colleagues (1978), Experiment 1 demonstrated that a manipulation of issue relevance enhanced the category salience of skin tone. Participants made more within- than between-category errors when the topic of conversation was related to perceiver's skin tone-based beliefs. Experiment 2 demonstrated that the influence of the issue relevance manipulation was independent of the presence of structural and/or normative fit. Merely discussing the topic of race relations was sufficient to increase encoding and use of skin tone. These studies provide evidence linking skin tone and social beliefs in memory. In addition, they demonstrate support for a category-based perspective in the study of skin tone bias. Additional factors affecting the salience of skin tone are discussed.

[source] Masculinity and the Biographical Meanings of Management Theory: Lyndall Urwick and the Making of Scientific Management in Inter-war BritainGENDER, WORK & ORGANISATION, Issue 2 2001Michael Roper This article explores the biographical shaping of management theory. Using the British management theorist Lyndall Urwick (1891,1983) as a case study, it argues that existing understandings of the history of management studies are limited by their lack of attention to the emotional a priori of theory production. For men such as Frederick Taylor or Urwick, the work of composing management theory for a public audience was intimately connected to events and experiences in the private life. Theorizing addressed emotional dilemmas even while it strove to construct a separation between the personal and the organizational. Management theories are not only historically, socially or discursively constructed, but can be read in terms of the evidence they provide about individual subjectivity. Psychoanalytic concepts can help illuminate such relations. Theorizing can be seen as a form of play: as something which, in D.W. Winnicott's terms, takes place in the space between the psychic reality of the ,me' and the external world of the ,not me'. The ,classical' administrative theory represented by Taylor, Fayol and Urwick sought to create organizational structures which could stand apart from, and allow the management of, individual personalities. It simultaneously insisted on the status of theory as the ,not me'; that is, as a product which was not shaped by personal experience, but which constituted objective knowledge. The illusion of theory as a largely external, social product persists in much management and organization studies today. This article challenges that social determinism, first, by showing how Urwick's theories addressed issues of separation and intimacy, and second, by placing Urwick's work in the context of his relations with women. [source] The Geologic Basis for a Reconstruction of a Grounded Ice Sheet in McMurdo Sound, Antarctica, at the Last Glacial MaximumGEOGRAFISKA ANNALER SERIES A: PHYSICAL GEOGRAPHY, Issue 2-3 2000George H. Denton A grounded ice sheet fed from the Ross Embayment filled McMurdo Sound at the last glacial maximum (LGM). This sheet deposited the little-weathered Ross Sea drift sheet, with far-traveled Transantarctic Mountains (TAM) erratics, on lower slopes of volcanic islands and peninsulas in the Sound, as well as on coastal forelands along the TAM front. The mapped upper limit of this drift, commonly marked by a distinctive moraine ridge, shows that the ice-sheet surface sloped landward across McMurdo Sound from 710 m elevation at Cape Crozier to 250 m in the eastern foothills of the Royal Society Range. Ice from the Ross Embayment flowed westward into the sound from both north and south of Ross Island. The northern flowlines were dominant, deflecting the southern flowlines toward the foothills of the southern Royal Society Range. Ice of the northern flowlines distributed distinctive kenyte erratics, derived from western Ross Island, in Ross Sea drift along the TAM front between Taylor and Miers Valleys. Lobes from grounded ice in McMurdo Sound blocked the mouths of TAM ice-free valleys, damming extensive proglacial lakes. A floating ice cover on each lake formed a conveyor that transported glacial debris from the grounded ice lobes deep into the valleys to deposit a unique glaciolacustrine facies of Ross Sea drift. The ice sheet in McMurdo Sound became grounded after 26,860 14C yr bp. It remained near its LGM position between 23,800 14C yr bp and 12,700 14C yr bp. Recession was then slow until sometime after 10,794 14C yr bp. Grounded ice lingered in New Harbor in the mouth of Taylor Valley until 8340 14C yr bp. The southward-retreating ice-sheet grounding line had penetrated deep into McMurdo Sound by 6500 14C yr bp. The existence of a thick ice sheet in McMurdo Sound is strong evidence for widespread grounding across the Ross Embayment at the LGM. Otherwise, the ice-sheet surface would not have sloped landward, nor could TAM erratics have been glacially transported westward into McMurdo Sound from farther offshore in the Ross Embayment. [source] Using Taylor Rules to Understand European Central Bank Monetary PolicyGERMAN ECONOMIC REVIEW, Issue 3 2007Stephan Sauer Taylor rule; European Central Bank; real-time data Abstract. Over the last decade, the simple instrument policy rule developed by Taylor has become a popular tool for evaluating the monetary policy of central banks. As an extensive empirical analysis of the European Central Bank's (ECB) past behaviour still seems to be in its infancy, we estimate several instrument policy reaction functions for the ECB to shed some light on actual monetary policy in the euro area under the presidency of Wim Duisenberg and answer questions like whether the ECB has actually followed a stabilizing or a destabilizing rule so far. Looking at contemporaneous Taylor rules, the evidence presented suggests that the ECB is accommodating changes in inflation and hence follows a destabilizing policy. However, this impression seems to be largely due to the lack of a forward-looking perspective in such specifications. Either assuming rational expectations and using a forward-looking specification, or using expectations as derived from surveys result in Taylor rules that do imply a stabilizing role of the ECB. The use of real-time industrial production data does not seem to play such a significant role as in the case of the United States.

[source] Evaluating best evaporation estimate model for water surface evaporation in semi-arid region, IndiaHYDROLOGICAL PROCESSES, Issue 8 2008Shakir Ali Abstract Evaluating performances of four commonly used evaporation estimate methods, namely; Bowen ratio energy balance (BREB), mass transfer (MT), Priestley,Taylor (PT) and pan evaporation (PE), based on 4 years experimental data, the most effective and the reliable evaporation estimates model for the semi-arid region of India has been derived. The various goodness-of-fit measures, such as; coefficient of determination (R2), index of agreement (D), root mean square error (RMSE), and relative bias (RB) have been chosen for the performance evaluation. Of these models, the PT model has been found most promising when the Bowen ratio, , is known a priori, and based on its limited data requirement. The responses of the BREB, the PT, and the PE models were found comparable to each other, while the response of the MT model differed to match with the responses of the other three models. The coefficients, , of the BREB, µ of the MT, , of the PT and KP of the PE model were estimated as 0·07, 2·35, 1·31 and 0·65, respectively. The PT model can successfully be extended for free water surface evaporation estimates in semi-arid India. A linear regression model depicting relationship between daily air and water temperature has been developed using the observed water temperatures and the corresponding air temperatures. The model helped to generate unrecorded water temperatures for the corresponding ambient air temperatures. Copyright © 2007 John Wiley & Sons, Ltd. [source] Comparison of seven models for estimation of evapotranspiration and groundwater recharge using lysimeter measurement data in GermanyHYDROLOGICAL PROCESSES, Issue 18 2005C.-Y. Xu Abstract This study evaluates seven evapotranspiration models and their performance in water balance studies by using lysimeter measurement data at the Mönchengladbach hydrological and meteorological station in Germany. Of the seven evapotranspiration models evaluated, three models calculate actual evapotranspiration directly using the complementary relationship approach, i.e. the CRAE model of Morton, the advection,aridity (AA) model of Brutsaert and Stricker, and the GG model of Granger and Gray, and four models calculate first potential evapotranspiration and then actual evapotranspiration by considering the soil moisture condition. Two of the four potential evapotranspiration models belong to the temperature-based category, i.e. the Thornthwaite model and the Hargreaves model, and the other two belong to the radiation-based category, i.e. the Makkink model and the Priestley,Taylor model. The evapotranspiration calculated by the above seven models, together with precipitation, is used in the water balance model to calculate other water balance components. The results show that, for the calculation of actual evapotranspiration, the GG model and the Makkink model performed better than the other models; for the calculation of groundwater recharge using the water balance approach, the GG model and the AA models performed better; for the simulation of soil moisture content using the water balance approach, four models (GG, Thornthwaite, Makkink and Priestley,Taylor) out of the seven give equally good results. It can be concluded that the lysimeter-measured water balance components, i.e. actual evapotranspiration, groundwater recharge, soil moisture, etc., can be predicted by the GG model and the Makkink model with good accuracy. Copyright © 2005 John Wiley & Sons, Ltd. [source] Improved four-node Hellinger,Reissner elements based on skew coordinatesINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING, Issue 6 2008K. Wisniewski Abstract Mixed four-node elements based on the Hellinger,Reissner (HR) functional are developed for stress representations in various coordinates, including the skew, natural and Cartesian ones. The two-field HR functional is used in the classical form and in the incremental form suitable for non-linear materials. We argue that the skew coordinates, not the natural ones, should be associated with the natural basis at the element's center. If 5- and 7-parameter stress representations are assumed in these coordinates, then, for a linear elastic case, the homogenous equilibrium equations and the stress form of compatibility equation are satisfied point-wise. Two mixed four-node elements are developed and tested: 1.An assumed stress element (HR5-S) is developed from the non-enhanced HR functional, for a 5-parameter representation of stresses, formally identical as the one used, for example, in Pian and Sumihara [Int. J. Numer. Meth. Engng 1984; 20:1685,1695], but in terms of skew coordinates. This element is very simple and uses a smaller number of parameters, but is equally accurate as the elements by Yuan et al. [Int. J. Numer. Meth. Engng 1993; 36:1747,1763] and by Piltner and Taylor [Int. J. Numer. Meth. Engng 1995; 38:1783,1808]. 2.An assumed stress/enhanced strain element (HR9) is developed from the enhanced HR functional, for a 7-parameter representation of stress and a 2-parameter enhanced assumed displacement gradient or enhanced assumed strain enhancement. Various forms of 7-parameter representations appearing in the literature are reviewed, and we prove that they are linked by a linear onto transformation. The choice of coordinates for the stress and the enhancement turns out to be the crucial factor, and four combinations of coordinates for which the element performs the best are identified. Both elements are based on the Green strain, and several numerical tests show their good accuracy, in particular, their robustness to shape distortions for coarse meshes. Two update schemes for the multipliers of modes and the incremental constitutive procedure accounting for the plane stress condition for non-linear materials are tested for large deformation problems.

[source] Parallel computing of high-speed compressible flows using a node-based finite-element methodINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING, Issue 3 2003T. Fujisawa Abstract An efficient parallel computing method for high-speed compressible flows is presented. The numerical analysis of flows with shocks requires very fine computational grids and grid generation requires a great deal of time. In the proposed method, all computational procedures, from the mesh generation to the solution of a system of equations, can be performed seamlessly in parallel in terms of nodes. Local finite-element mesh is generated robustly around each node, even for severe boundary shapes such as cracks. The algorithm and the data structure of finite-element calculation are based on nodes, and parallel computing is realized by dividing a system of equations by the row of the global coefficient matrix. The inter-processor communication is minimized by renumbering the nodal identification number using ParMETIS. The numerical scheme for high-speed compressible flows is based on the two-step Taylor,Galerkin method. The proposed method is implemented on distributed memory systems, such as an Alpha PC cluster, and a parallel supercomputer, Hitachi SR8000. The performance of the method is illustrated by the computation of supersonic flows over a forward facing step. The numerical examples show that crisp shocks are effectively computed on multiprocessors at high efficiency. Copyright © 2003 John Wiley & Sons, Ltd. [source] Efficient preconditioning techniques for finite-element quadratic discretization arising from linearized incompressible Navier,Stokes equationsINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, Issue 12 2010A. El Maliki Abstract We develop an efficient preconditioning techniques for the solution of large linearized stationary and non-stationary incompressible Navier,Stokes equations. These equations are linearized by the Picard and Newton methods, and linear extrapolation schemes in the non-stationary case. The time discretization procedure uses the Gear scheme and the second-order Taylor,Hood element P2,P1 is used for the approximation of the velocity and the pressure. Our purpose is to develop an efficient preconditioner for saddle point systems. Our tools are the addition of stabilization (penalization) term r,(div(·)), and the use of triangular block matrix as global preconditioner. This preconditioner involves the solution of two subsystems associated, respectively, with the velocity and the pressure and have to be solved efficiently. Furthermore, we use the P1,P2 hierarchical preconditioner recently proposed by the authors, for the block matrix associated with the velocity and an additive approach for the Schur complement approximation. Finally, several numerical examples illustrating the good performance of the preconditioning techniques are presented. Copyright © 2009 John Wiley & Sons, Ltd. [source] Method of fundamental solutions for partial-slip fibrous filtration flowsINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, Issue 3 2009Shunliu Zhao Abstract In this study a Stokeslet-based method of fundamental solutions (MFS) for two-dimensional low Reynolds number partial-slip flows has been developed. First, the flow past an infinitely long cylinder is selected as a benchmark. The numerical accuracy is investigated in terms of the location and the number of the Stokeslets. The benchmark study shows that the numerical accuracy increases when the Stokeslets are submerged deeper beneath the cylinder surface, as long as the formed linear system remains numerically solvable. The maximum submergence depth increases with the decrease in the number of Stokeslets. As a result, the numerical accuracy does not deteriorate with the dramatic decrease in the number of Stokeslets. A relatively small number of Stokeslets with a substantial submergence depth is thus chosen for modeling fibrous filtration flows. The developed methodology is further examined by application to Taylor,Couette flows. A good agreement between the numerical and analytical results is observed for no-slip and partial-slip boundary conditions. Next, the flow about a representative set of infinitely long cylindrical fibers confined between two planar walls is considered to represent the fibrous filter flow. The obtained flowfield and pressure drop agree very well with the experimental data for this setup of fibers. The developed MFS with submerged Stokeslets is then applied to partial-slip flows about fibers to investigate the slip effect at fiber,fluid interface on the pressure drop. The numerical results compare qualitatively with the analytical solution available for the limit case of infinite number of fibers. Copyright © 2008 John Wiley & Sons, Ltd. [source] High-order stable interpolations for immersed boundary methodsINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, Issue 11 2006Nikolaus Peller Abstract The analysis and improvement of an immersed boundary method (IBM) for simulating turbulent flows over complex geometries are presented. Direct forcing is employed. It consists in interpolating boundary conditions from the solid body to the Cartesian mesh on which the computation is performed. Lagrange and least squares high-order interpolations are considered. The direct forcing IBM is implemented in an incompressible finite volume Navier,Stokes solver for direct numerical simulations (DNS) and large eddy simulations (LES) on staggered grids. An algorithm to identify the body and construct the interpolation schemes for arbitrarily complex geometries consisting of triangular elements is presented. A matrix stability analysis of both interpolation schemes demonstrates the superiority of least squares interpolation over Lagrange interpolation in terms of stability. Preservation of time and space accuracy of the original solver is proven with the laminar two-dimensional Taylor,Couette flow. Finally, practicability of the method for simulating complex flows is demonstrated with the computation of the fully turbulent three-dimensional flow in an air-conditioning exhaust pipe.

[source] Transition from vortex to wall driven turbulence production in the Taylor,Couette system with a rotating inner cylinderINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, Issue 3 2002W. M. J. Batten Abstract Axisymmetrically stable turbulent Taylor vortices between two concentric cylinders are studied with respect to the transition from vortex to wall driven turbulent production. The outer cylinder is stationary and the inner cylinder rotates. A low Reynolds number turbulence model using the k - , formulation, facilitates an analysis of the velocity gradients in the Taylor,Couette flow. For a fixed inner radius, three radius ratios 0.734, 0.941 and 0.985 are employed to identify the Reynolds number range at which this transition occurs. At relatively low Reynolds numbers, turbulent production is shown to be dominated by the outflowing boundary of the Taylor vortex. As the Reynolds number increases, shear driven turbulence (due to the rotating cylinder) becomes the dominating factor. For relatively small gaps turbulent flow is shown to occur at Taylor numbers lower than previously reported. Copyright © 2002 John Wiley & Sons, Ltd. [source] A dynamic key management solution to access hierarchyINTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 6 2007Xukai Zou Hierarchical access control (HAC) has been a fundamental problem in computer and network systems. Since Akl and Taylor proposed the first HAC scheme based on number theory in 1983, cryptographic key management techniques for HAC have appeared as a new and promising class of solutions to the HAC problem. Many cryptographic HAC schemes have been proposed in the past two decades. One common feature associated with these schemes is that they basically limited dynamic operations at the node level. In this paper, by introducing the innovative concept of ,access polynomial' and representing a key value as the sum of two polynomials in a finite field, we propose a new key management scheme for dynamic access hierarchy. The newly proposed scheme supports full dynamics at both the node level and user level in a uniform yet efficient manner. Furthermore, the new scheme allows access hierarchy to be a random structure and can be flexibly adapted to many other access models such as ,transfer down' and ,depth-limited transfer'.

Exploring an international definition of social work in the China context'[International Journal of Social Welfare 16: 381,389], no doubt had good intentions in offering their account of the development of social work in China, as the opening and concluding sections of the article show. Within the text, however, their critique of contemporary social work in China is, in my opinion, unfair in relation to, among other things, (i) the undemocratic nature of the Chinese political system, which they say hinders the development of social work in China; (ii) the ideology of the Communist Party, the government, and traditional Chinese culture, which they say are at odds with Western social work's value system and methodology; thus concluding that (iii) it is doubtful whether social work development in China could integrate with that of the international community. In this response, I comment on (i) the information base of the authors; (ii) the disconnection between their conceptualisation and historical facts; and (iii) their use of the international definition of social work. [source] Challenging East,West value dichotomies and essentialising discourse on culture and social workINTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 4 2007Vishanthie SewpaulArticle first published online: 22 MAR 200 All discourse, whether universalistic and/or particularistic, must be subject to contestation, so that we are held accountable for the thinking that we articulate in our writings, and so that we do not reinforce much of the taken for granted assumptions about the world. Critiques such as those of Hutchings and Taylor in this issue of IJSW remind us of social work's commitment to reflexivity and the need to contest discourse that might not be in the interests of particular groups of people. It is not the debate itself contained in the article that is an issue, but the framing of the debate and the assumptions upon which they are predicated. The discourse on human rights within the liberal democratic framework, in a rapidly globalising world characterised by neoliberal capitalism, needs to be critiqued on a global level. Hutchings and Taylor's article assumes the applicability and suitability of liberal democracy for the West and not for the East, with an assumption that the West is characterised by liberalism and the East by tradition and a bureaucratic authoritarianism. It is these assumptions, and the tendency to essentialise Chinese and Western culture and to reinforce the dichotomy between the West and the East, that I contest in this article.

Peter McGraw Abstract Positive illusions, though often beneficial (Taylor & Brown, 1988), can diminish the pleasure of outcomes. This prediction follows from decision affect theory. We investigated this prediction by measuring the confidence that recreational basketball players felt while making shots and the pleasure they felt with subsequent outcomes. Results showed that most players were overconfident. Those who were more overconfident tended to experience less enjoyment with their outcomes. Using individual parameter estimates from decision affect theory, we estimated how each player would have felt if their self assessments had been accurate. For the vast majority, better calibration would have led to greater pleasure. In a second study, we randomly assigned players to a debiasing treatment condition or a control condition. Relative to the control players, debiased players were better calibrated and derived greater average pleasure from the task. Copyright © 2004 John Wiley & Sons, Ltd.
