Selected AbstractsAutoassociator networks: insights into infant cognitionDEVELOPMENTAL SCIENCE, Issue 2 2004Sylvain Sirois This paper presents autoassociator neural networks. A first section reviews the architecture of these models, common learning rules, and presents sample simulations to illustrate their abilities. In a second section, the ability of these models to account for learning phenomena such as habituation is reviewed. The contribution of these networks to discussions about infant cognition is highlighted. A new, modular approach is presented in a third section. In the discussion, a role for these learning models in a broader developmental framework is proposed. [source] Standard-Setting Methods as Measurement ProcessesEDUCATIONAL MEASUREMENT: ISSUES AND PRACTICE, Issue 1 2010Paul Nichols Some writers in the measurement literature have been skeptical of the meaningfulness of achievement standards and described the standard-setting process as blatantly arbitrary. We argue that standard setting is more appropriately conceived of as a measurement process similar to student assessment. The construct being measured is the panelists' representation of student performance at the threshold of an achievement level. In the first section of this paper, we argue that standard setting is an example of stimulus-centered measurement. In the second section, we elaborate on this idea by comparing some popular standard-setting methods to the stimulus-centered scaling methods known as psychophysical scaling. In the third section, we use the lens of standard setting as a measurement process to take a fresh look at the two criticisms of standard setting: the role of judgment and the variability of results. In the fourth section, we offer a vision of standard-setting research and practice as grounded in the theory and practice of educational measurement. [source] Energy tax harmonization in the European Union: a proposal based on the internalization of environmental external costsENVIRONMENTAL POLICY AND GOVERNANCE, Issue 1 2002Susanna Dorigoni Energy tax harmonization represents a fundamental target within the European Union. In fact fiscal harmonization is a crucial step towards the creation of a single market. In this article the possibility of achieving such an objective is discussed. The paper consists of two sections. In the first the European taxation on energy products is analysed. This analysis is useful in showing the differences that exist between the European countries that account for the difficulties met so far in the process of harmonization. In this respect we comment on the recent proposal of the Directive of the European Union, which lays down the obligation of minimum levels of taxation in all European member states. In the second section, after simulating the effects related to the adoption of a common environmental taxation (a first best solution based on the internalization of environmental external costs), we propose, as a second best solution, an excise tax harmonization model taking into consideration the specificity of each country and being, as far as possible, coherent with the environmental objective. This model proposes: the introduction of a minimum level of taxation on all products equal to the external cost due to the greenhouse effect (a common carbon tax); the possibility, given to the member states, of deviating from such minimum levels, in accordance with their specific requirements, internalizing in the price of the different products, by means of taxes additional to that CO2 minimum, the external costs associated with other pollutant agents (the same in all countries); the opportunity, in case it should be necessary to exceed the entire external cost, for the member states to apply increases that are in accordance with the environmental objective.

Conlon String compactifications represent the most promising approach towards unifying general relativity with particle physics. However, naive compactifications give rise to massless particles (moduli) which would mediate unobserved long-range forces, and it is therefore necessary to generate a potential for the moduli. In the introductory chapters I review this problem and recall how in IIB compactifications the dilaton and complex structure moduli can be stabilised by 3-form fluxes. There exist very many possible discrete flux choices which motivates the use of statistical techniques to analyse this discretuum of choices. Such approaches generate formulae predicting the distribution of vacua and I describe numerical tests of these formulae on the Calabi-Yau ,4[1,1,2,2,6]. Stabilising the Kähler moduli requires nonperturbative superpotential effects. I review the KKLT construction and explain why this must in general be supplemented with perturbative Kähler corrections. I show how the incorporation of such corrections generically leads to non-supersymmetric minima at exponentially large volumes, giving a detailed account of the,, expansion and its relation to Kähler corrections. I illustrate this with explicit computations for the Calabi-Yau ,4[1,1,1,6,9]. The next part of the article examines phenomenological applications of this construction. I first describe how the magnitude of the soft supersymmetry parameters may be computed. In the large-volume models the gravitino mass and soft terms are volume-suppressed. As we naturally have ,, ,1, this gives a dynamical solution of the hierarchy problem. I also demonstrate the existence of a fine structure in the soft terms, with gaugino masses naturally lighter than the gravitino mass by a factor ln (MP/m3/2). A second section gives a detailed analysis of the relationship of moduli stabilisation to the QCD axions relevant to the strong CP problem, proving a no-go theorem on the compatibility of a QCD axion with supersymmetric moduli stabilisation. I describe how QCD axions can coexist with nonsupersymmetric perturbative stabilisation and how the large-volume models naturally contain axions with decay constants that are phenomenologically allowed and satisfy the appealing relationship fa2 ,MPMsusy. A further section describe how a simple and predictive inflationary model can be built in the context of the above large-volume construction, using the no-scale Kähler potential to avoid the , problem. I finally conclude, summarising the phenomenological scenario and outlining the prospects for future work. [source] Heat and mass transfer phenomena in magnetic fluidsGAMM - MITTEILUNGEN, Issue 1 2007Th. Völker Abstract In this article the influence of a magnetic field on heat and mass transport phenomena in magnetic fluids (ferrofluids) will be discussed. The first section is dealing with a magnetically driven convection, the so called thermomagnetic convection while in the second section the influence of a temperature gradient on the mass transport, the Soret effect in ferrofluids, is reviewed.

In the first section we outline the apparel commodity chain and offer a brief typology of its lead firms. In the second section we discuss the concept of industrial upgrading and describe several main export roles in the global apparel industry. In the third section we focus on the regional dynamics resulting from the North American Free Trade Agreement (NAFTA). We contrast the Mexican experience with that of countries in the Caribbean Basin to show the impact of distinct trade policies on export-oriented development. We argue that NAFTA is creating upgrading opportunities for some Mexican firms to move from the low value-added export-oriented assembly (or maquila) model to full-package production. In the fourth section we explore the unevenness of upgrading dynamics through a comparison of two blue jeans manufacturing clusters in the United States and Mexico: El Paso and Torreon. Our conclusions about upgrading and uneven development in the North American apparel industry emphasize the importance of local, national and regional institutional contexts in shaping inter-firm networks and their development impact. [source] The E-economy and the Rise of Technocapitalism: Networks, Firms, and TransportationGROWTH AND CHANGE, Issue 4 2003Luis Suarez-Villa ABSTRACT The e-economy is part of a larger phenomenon, technocapitalism, that is transforming business organizations and the ways in which they transact, produce, and ship their goods. Technocapitalism is an evolution of market capitalism that is rooted in technological innovation and supported by such intangibles as creativity and knowledge. This paper considers first the main characteristics of networks that support the e-economy and its source phenomenon, the emergence of technocapitalism. Networks are thought to be the main vehicle through which the e-economy spreads, and they have major effects on the organization of business firms. The culture of technocapitalism, with its emphasis on continuous innovation and rapid adjustment, is largely behind the rising importance of networks. A second section then considers the deconstruction of business firms and its relation to networks, the e-economy, and the rise of technocapitalism. A historical perspective is provided to show the contrast with previous eras. The deconstruction of business organizations involves a major transformation of the norms and ways in which firms are run and structured. Finally, the likely implications for transportation and shipping of the rise of the e-economy, its networks, and the deconstruction of firms are discussed. The logistics, pricing, and infrastructure of shipping are likely to be substantially affected by the spread of the e-economy, its networks, and the deconstruction of firms. [source] Ethical aspects of technical safetyHUMAN FACTORS AND ERGONOMICS IN MANUFACTURING & SERVICE INDUSTRIES, Issue 3 2003Carl Friedrich Gethmann Uncertainty and inequality are the most important phenomena that lead to the situation in which the modern technical age, in contrast to the premodern technical phase, gives rise to specifically moral problems which in the premodern era played only a marginal role or no role at all. So modern, technically constituted societies must learn to develop from the initial perception of dangers to a rational risk assessment. To justify this ethical obligation, the first section discusses the relation between danger and risk. The problem of weighing risks is analyzed in the second section; in this context the concept of pragmatic consistency is introduced. In the third section, the term safety is explicated as a comparative concept by means of the principle of pragmatic consistency. © 2003 Wiley Periodicals, Inc. Hum Factors Man 13: 243,252, 2003. [source] A finite volume solver for 1D shallow-water equations applied to an actual riverINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, Issue 1 2002N. Gouta Abstract This paper describes the numerical solution of the 1D shallow-water equations by a finite volume scheme based on the Roe solver. In the first part, the 1D shallow-water equations are presented. These equations model the free-surface flows in a river. This set of equations is widely used for applications: dam-break waves, reservoir emptying, flooding, etc. The main feature of these equations is the presence of a non-conservative term in the momentum equation in the case of an actual river. In order to apply schemes well adapted to conservative equations, this term is split in two terms: a conservative one which is kept on the left-hand side of the equation of momentum and the non-conservative part is introduced as a source term on the right-hand side. In the second section, we describe the scheme based on a Roe Solver for the homogeneous problem. Next, the numerical treatment of the source term which is the essential point of the numerical modelisation is described. The source term is split in two components: one is upwinded and the other is treated according to a centred discretization. By using this method for the discretization of the source term, one gets the right behaviour for steady flow. Finally, in the last part, the problem of validation is tackled. Most of the numerical tests have been defined for a working group about dam-break wave simulation. A real dam-break wave simulation will be shown. Copyright © 2002 John Wiley & Sons, Ltd. [source] Marital Processes and Parental Socialization in Families of Color: A Decade Review of ResearchJOURNAL OF MARRIAGE AND FAMILY, Issue 4 2000Vonnie C. McLoyd Research published during the past decade on African American, Latino, and Asian American families is reviewed. Emphasis is given to selected issues within the broad domains of marriage and parenting. The first section highlights demographic trends in family formation and family structure and factors that contributed to secular changes in family structure among African Americans. In the second section, new conceptualizations of marital relations within Latino families are discussed, along with research documenting the complexities in African American men's conceptions of manhood. Studies examining within-group variation in marital conflict and racial and ethnic differences in division of household labor, marital relations, and children's adjustment to marital and family conflict also are reviewed. The third section gives attention to research on (a) paternal involvement among fathers of color; (b) the relation of parenting behavior to race and ethnicity, grandmother involvement, neighborhood and peer characteristics, and immigration; and (c) racial and ethnic socialization. The article concludes with an overview of recent advances in the study of families of color and important challenges and issues that represent research opportunities for the new decade. [source] Kierkegaard on the Problems of Pure IronyJOURNAL OF RELIGIOUS ETHICS, Issue 3 2004Brad Frazier ABSTRACT Søren Kierkegaard's thesis, The Concept of Irony, contains an interesting critique of pure irony. Kierkegaard's critique turns on two main claims: (a) pure irony is an incoherent and thus, unrealizable stance; (b) the pursuit of pure irony is morally enervating, psychologically destructive, and culminates in bondage to moods. In this essay, first I attempt to clarify Kierkegaard's understanding of pure irony as "infinite absolute negativity." Then I set forth his multilayered critique of pure irony. Finally, I consider briefly a distinctly theological component in Kierkegaard's critique. I argue that this feature of Kierkegaard's account can and should be distinguished from the broadly ethical critique of pure irony that I sketch in the second section, even if these components of Kierkegaard's position are found together as a unified whole in The Concept of Irony. My overall goal in this essay is to reveal the subtlety and plausibility of Kierkegaard's critique of pure irony. I also attempt to disclose the richness of the Hegelian account of ethical life to which Kierkegaard recurs in his thesis. [source] Language and the Measure of MindMIND & LANGUAGE, Issue 4 2010ELI DRESNER In his recent book The Measure of Mind Robert Matthews presents the most elaborate and convincing attempt to date to account for the propositional attitudes in measurement theoretic terms. In the first section of this paper I review earlier applications of measurement-theoretic conceptualization to the discussion of the mind, I outline Matthews' own account, and I raise two questions concerning it. Then, in the second section of the paper, I present a unified measurement-theoretic account of both linguistic meaning and the propositional attitudes, in which a variant of Matthews' position is embedded. Such a unified account, I argue, yields satisfactory answers to the questions raised with respect to Matthews' original view, and demonstrates other advantages. [source] Undecidable and decidable restrictions of Hilbert's Tenth Problem: images of polynomials vs. images of exponential functionsMLQ- MATHEMATICAL LOGIC QUARTERLY, Issue 1 2006Mihai Prunescu Abstract Classical results of additive number theory lead to the undecidability of the existence of solutions for diophantine equations in given special sets of integers. Those sets which are images of polynomials are covered by a more general result in the second section. In contrast, restricting diophantine equations to images of exponential functions with natural bases leads to decidable problems, as proved in the third section. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source] Cystic fibrosis lung disease starts in the small airways: Can we treat it more effectively?PEDIATRIC PULMONOLOGY, Issue 2 2010Harm A.W.M. Tiddens MD Abstract The aims of this article are to summarize existing knowledge regarding the pathophysiology of small airways disease in cystic fibrosis (CF), to speculate about additional mechanisms that might play a role, and to consider the available or potential options to treat it. In the first section, we review the evidence provided by pathologic, physiologic, and imaging studies suggesting that obstruction of small airways begins early in life and is progressive. In the second section we discuss how the relationships between CF transmembrane conductance regulator (CFTR), ion transport, the volume of the periciliary liquid layer and airway mucus might lead to defective mucociliary clearance in small airways. In addition, we discuss how chronic endobronchial bacterial infection and a chronic neutrophilic inflammatory response increase the viscosity of CF secretions and exacerbate the clearance problem. Next, we discuss how the mechanical properties of small airways could be altered early in the disease process and how remodeling can contribute to small airways disease. In the final section, we discuss how established therapies impact small airways disease and new directions that may lead to improvement in the treatment of small airways disease. We conclude that there are many reasons to believe that small airways play an important role in the pathophysiology of (early) CF lung disease. Therapy should be aimed to target the small airways more efficiently, especially with drugs that can correct the basic defect at an early stage of disease.

[source] The Politics of Perception: Use and Abuse of Transparency International's Approach to Measuring CorruptionPOLITICAL STUDIES, Issue 4 2009Staffan Andersson The annual Corruption Perceptions Index (CPI), published by Transparency International (TI), has had a pivotal role in focusing attention on corruption. Despite recent critiques of the CPI, it remains highly influential on research into the causes of corruption and is also extensively used to galvanise support for measures to fight corruption. In this article we explore the CPI in more depth in order to highlight how the index has been used for political ends which may not always turn out to be supportive of anti-corruption efforts. The argument is developed in four sections: in the first, we focus on Transparency International's definition of corruption, highlighting some conceptual difficulties with the approach adopted and its relationship to the promotion of ,good governance' as the principal means of combating corruption. In the second section, we outline some methodological difficulties in the design of the Corruption Perceptions Index. Although the CPI has been much criticised, we demonstrate in the third section that the index continues to exercise great influence both in academic research and in the politics of anti-corruption efforts, particularly as exercised by Transparency International itself. In the final section we argue that the CPI contributes to the risk of creating a ,corruption trap' in countries where corruption is deeply embedded, as development aid is increasingly made conditional on the implementation of reforms which are impossible to achieve without that aid. [source] Perils of religion: need for spirituality in the public spherePUBLIC ADMINISTRATION & DEVELOPMENT, Issue 2 2006Paul Collins Abstract On both sides of the Atlantic, there is increased professional concern over roles in international public sector management,whether those of the policy makers, administrators or consultants. Growing numbers across many sectors feel an unprecedented crisis of identity and integrity. In international development, institutions often find themselves subordinated to the military in ever increasing conflict situations (the ,development-security complex'). Locally, the global tendency is for public administration to be ,re-engineered' on the basis of so-called ,market' values (the ,New Public Administration'). Private sector management models are, nevertheless, hardly exemplary. Corporate greed and scandals proliferate in a world featuring increasing poverty extremes, resurgence of old or advent in new diseases (e.g. HIV/Aids), environmental degradation and racism. This article takes, as its starting point, the fact that the workplace has become an insecure and alienating environment. In pursuing the relationship between spirituality and religion, the article next distinguishes between, the dogmatic, institutionalised and potentially dangerous characteristics of many religions and the more intuitively contemplative character of spirituality with its stress on awareness of self, impact on others and feeling of universal connectedness. Bearing in mind the often extremism as well as variety of religions (as distinct from spirituality), the second section examines the interrelationship between the two. A number of models are advanced concerning relationships between belief, belonging, salvation and ritual. It is argued that attention needs to be given to the inner side of religion, which requires individuals to embark on a spiritual journey through contemplation and reflection, rather than the more visible side of religion expressed in ritual. In sum, spiritual dialogue is offered as a way forward and as a mechanism for building spiritual community through engagement. The final part of the article focuses on a trans-Atlantic spiritual engagement initiative. Faith-based discussion groups have been formed amongst business executives and professionals in USA (the Woodstock Business Conference promoted out of Georgetown University) and more recently in the City of London at the St Paul's Cathedral Institute (the Paternoster Pilot Group). These aim to develop more meaningful work orientation: rediscovery of higher purpose and its relevance to restoration of ethical business and public service values, as well as better integration of personal and social domains.

[source] Tackling the paradox: can attaining global research excellence be compatible with local technology development?R & D MANAGEMENT, Issue 1 2004Johan Van Helleputte This paper uses the case of the IMEC (microelectronics research centre) to examine the compatibility between strategic IPR management of large independent research centres, and regional industrial policy missions given to such centres in return for government funding. In particular, the issue of whether a balance can be found between a necessary drive for international recognition and critical mass of funding, and a policy of IPR valorization towards regional firms is examined. The first section sets out the mission of IMEC and the evolution over time of its strategic approach to building global industrial partnerships based on a sophisticated model of IPR management. Drawing on a recent evaluation, the subject of the second section is the extent to which the results of the industrial and exploratory research activities of IMEC are then commercialized in local Flemish industry. The concluding section offers policy conclusions in terms of the instruments and objectives which public policy makers can apply to maximize the local impact of large globally operating research centres. [source] Practitioner Review: Use of antiepileptic drugs in childrenTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 2 2006Renzo Guerrini Background:, The aim in treating epilepsy is to minimise or control seizures with full respect of quality-of-life issues, especially of cognitive functions. Optimal treatment first demands a correct recognition of the major type of seizures, followed by a correct diagnosis of the type of epilepsy or of the specific syndrome. Methods:, Review of data from literature and personal clinical experience in treating children with epilepsy. Results:, After summarising the general aspects on the diagnosis and treatment of the main forms of childhood epilepsy, we review key issues about management of seizure disorders, including when to start treatment, how to proceed when the first treatment fails, and how to set the targets of treatment. A special section is devoted to the new concept of epileptic encephalopathy and to the influence of ,interictal' EEG abnormalities on cognition, behaviour, and motor abilities in children, providing some suggestions on why and how to treat these conditions. A second section approaches the choice of treatment according to the specific syndromes including infantile spasms, focal epilepsies, syndromes with typical absence seizures, the myoclonic epilepsies and the Lennox,Gastaut syndrome. Conclusions:, Antiepileptic drugs (AEDs) can efficiently control seizures in most children. However, the specificity of AEDs is relatively limited, although continuing research is leading to a better understanding of the relationship between pathogenesis and the mechanism(s) and site(s) of drug action. [source] Values of Children, Parent,Child Relationship, and Social Change in Korea: Indigenous, Cultural, and Psychological AnalysisAPPLIED PSYCHOLOGY, Issue 3 2005Uichol Kim Les recherches sur les valeurs que les parents attribuent aux enfants se demandent pourquoi les gens décident ou non d'avoir des enfants et s'intéressent au nombre d'enfants qu'ils choisissent d'avoir. On décrit dans la première partie de cet article la relation parents-enfants traditionnelle, la structure familiale et les changements sociaux qui se sont produits ces cinquante dernières années en Corée du sud. On présente dans la deuxième partie les résultats de l'étude de 1972 sur les valeurs attribuées aux enfants réalisée en Corée du sud (Lee & Kim, 1975). Dans la dernière partie, on expose une recherche empirique sud-coréenne portant sur un échantillon de 314 jeunes mères et 395 mères plus âgées. Il apparaît que les bénéfices psychologiques sont les raisons majeures qui justifient le choix d'avoir un enfant et que les contraintes personnelles et financières sont les motifs dominants de ne pas en avoir. Ces résultats mettent en défaut les modèles économiques et utilitaires et soulignent l'importance des facteurs psychologiques, relationnels et culturels. Research on parents' attribution of value to children examines why people decide to have children or not and the number of children they choose to have. In the first part of this paper, the traditional parent,child relationship, family structure, and social changes that have occurred in South Korea during the past 50 years are reviewed. In the second section, the results of the 1972 Values of Children Study conducted in South Korea (Lee & Kim, 1975) are reviewed. In the final section, an empirical study conducted in South Korea with a sample of 314 young mothers and 395 older mothers is reported. The results indicate that psychological benefits are the most important reasons for having a child and personal and financial constraints are the most important reasons for not having a child. These results challenge the economic and utilitarian models and suggest the importance of understanding the psychological, relational, and cultural factors. [source] Value Pluralism and Multinational FederalismAUSTRALIAN JOURNAL OF POLITICS AND HISTORY, Issue 1 2004Ferran Requejo This article is mainly concerned with the notion of value pluralism. In the first section I present it as a theory of the structure of moral normativity in liberal democracies, and defend its greater suitability compared with rival theories in attempting to revise democratic liberalism from the perspective of the cultural, national and normative pluralism of present-day democracies. In the second section, I link value pluralism with multinational federations in order to discuss its role in establishing the recognition of national pluralism, a plurinational division of powers, the participation of the different national collectives in the processes of constitutional reform, and the constitutional regulation of the right of self-determination, following the 1998 decision of the Canadian Supreme Court. [source] Beyond Being Marginal: Gender and International Relations in BritainBRITISH JOURNAL OF POLITICS & INTERNATIONAL RELATIONS, Issue 2 2007Judith Squires In this introduction, we situate ,gender and international relations in Britain'. We discuss our understandings of gender, I/international R/relations and GIR. In the second section we discuss the relationship of feminist to gendered IR, arguing that while intimately related, they are nonetheless not synonymous. We turn in the third section to a critical discussion of feminist IR's tendency to see itself as marginal to mainstream IR, a move that contributes to the marginalisation it laments. In the fourth section we compare the development of GIR with gender in Politics, which has been less concerned from the outset with issues of marginality. In the final section we argue that GIR has come into its own, introducing the articles in this issue as instances of self-assured gendered analyses of ,things international'.
