Explaining after by before: Basic aspects of a dynamic systems approach to the study of development

The basic properties of a dynamic systems approach of development are illustrated by contrasting two simple equations. One, y_t+1 = f (y_t), is characteristic of dynamic systems models. The other, y_i = f (x_i), refers to what, for the sake of simplicity, is referred to as the standard developmental approach. We give illustrations from cognitive, language and social development to show the characteristic differences of these two types of models and show their complementarity. The article further compares the “Bloomington” with the “Groningen” approach to dynamic systems theorizing in developmental psychology. It continues with a discussion of two important questions. One involves the issue of measurement and the nature of developmental variables from the viewpoint of dynamic systems. The second concerns the question of short- and long-term time scales in developmental models, which is discussed on the basis of an example, namely dyadic interaction of young children in the context of different social statuses.     

Transcendence of the Ego (The Non-Existent Knight)

I exist, but I am not a thing among things; X exists if and only if there is something such that it=X. This is consistent, and it is a view that can be supported. Calvino’s novel The Non‐Existent Knight can be read so as to illustrate this view. But what is my relation to the things there are if I am not identical with any of them – things such as my arms, my garden, the city I live in? I name this the Gurduloo problem, after the Knight’s page. This relation must be one that admits of degrees; I suggest that we say that I manifest myself through the things thus associated with me. Several pseudo‐problems, pertaining to volitional action, supervenience, observability, and the emergence of consciousness, dissolve upon inspection.     

Job search and the theory of planned behavior: Minority-majority group differences in The Netherlands

The labor market in many Western countries increasingly diversifies. However, little is known about job search behavior of “non-traditional” applicants such as ethnic minorities. This study investigated minority-majority group differences in the predictors of job search behavior, using the theory of planned behavior (Ajzen, 1985). Data were collected in a two-wave longitudinal design among 697 temporary employees in The Netherlands. Results showed that the ethnic minorities' perceptions of social pressure predicted intentions to search for a (new) job more strongly than their personal attitudes did. The opposite was found in the native-Dutch group. Self-efficacy did not contribute to the prediction of job search intention. Job search behavior related significantly to job search outcomes, such as job attainment.     

Social Dominance Theory: Its Agenda and Method

The theory has been misconstrued in four primary ways, which are often expressed as the claims of psychological reductionism, conceptual redundancy, biological reductionism, and hierarchy justification. This paper addresses these claims and suggests how social dominance theory builds on and moves beyond social identity theory and system justification theory.     

Innovation in open source communities through processes of variation and selection

This article concerns the question how innovation is achieved in open source communities. Open source communities are collections of geographically distributed individuals, who volunteer or are paid to participate in the development of highly innovative software programs. These communities are argued to be self-organizing systems in which high levels of variation are achieved. Next, this article focuses on selection as part of innovation. It is shown that selection is achieved through a rather simple principle of copying and following tags. Four tags are identified and discussed and it is demonstrated how they lead to the selection of software among the great level of variety. Ruben van Wendel de Joode is a Ph.D. student. He is part of Betade, which is one of the Delft interfaculty research centers; and the Dutch Institute of Government (NIG), the research school for public administration and political science. His Ph.D. research, scheduled to be finished mid 2004, focuses on open source. He has published numerous articles on OSS.     

Shedding Dialectical Tiers: A Social-Epistemic View

Is there a duty to respond to objections in order to present a good argument? Ralph Johnson argues that there is such a duty, which he refers to as the “dialectical tier“ of an argument. I deny the (alleged) duty primarily on grounds that it would exert too great a demand on arguers, harming argumentation practices. The valuable aim of responding to objections, which Johnson 's dialectical tier is meant to satisfy, can be achieved in better ways, as argumentation is a social-epistemic activity.     

Response inhibition in children with conduct disorder and borderline intellectual functioning.

The aim of the study was to investigate impulse control in children with conduct disorder (CD) plus borderline intellectual functioning (BIF), in children with BIF-only, and in a control group with a normal IQ. For this purpose, a Go-No-Go test with varying inter-stimulus-intervals was used. The group CD plus BIF made more errors of commission than the group with BIF only. Therefore, it was concluded that poor impulse control in the group CD plus BIF was associated with CD, not with IQ level. Poor impulse control in the group CD plus BIF was independent of the presentation rate of the stimuli.     

Antecedents and Components of Majority Attitudes toward Multiculturalism in the Netherlands

Les prédicteurs et les composantes des attitudes envers le multiculturalisme ont étéétudies chez 341 Néerlandais tout‐venant. Les attitudes relèvent d’une structure unidimensionnelle, mais le niveau d’adhésion au multiculturalisme varie significativement selon les domaines. Le niveau culturel et le fait de vivre en ville avec peu d’immigrés étaient les seules variables positivement corrélées avec l’adhésion au multiculturalisme. Un modèle en pistes causales s’est révélé pertinent, les attitudes et les comportements dépendant des variables psychologiques suivantes; connaissances, satisfaction générale, perspectives d’avenir, désirabilité sociale et perception des normes sociales favorables au multiculturalisme ou en faisant au contraire une menace. Globalement, l’exclusion était désapprouvée par la majorité des Néerlandais, mais le pluralisme culturel nétait pas ressenti comme étant un atout précieux pour leur société, et ils nétaient pas disposés à faire beaucoup d’efforts pour faciliter l’intégration des minorités. Predictors and components of attitudes toward multiculturalism were studied in 341 native Dutch people. Attitudes were found to have a unidimensional structure, but the level of support for multiculturalism was found to vary significantly over societal domains. Level of education and living in city districts with few non‐natives were the only background variables that were (positively) related to support for multiculturalism. A path model, with psychological background variables (knowledge, life satisfaction, life opportunities, perceived social norms about multiculturalism as a threat and support for multiculturalism, and social desirability) predicting attitudes and behavior, showed a good fit. Generally, exclusionist positions were not endorsed by majority Dutch, but cultural pluralism was not seen as a valuable asset of their society, and they are not inclined to put much effort into minority integration.
