The individuals with autism reported impairment on all AQ subscales, compared to the neurotypical group. The schizophrenia group reported deficits on all subscales except Attention to detail, compared to the neurotypical group. The autism group reported more impairment than the individuals with schizophrenia in Social skill, Communication and Attention switching.

Usually they are collected in object by category matrices with the property that rows of this data matrix add up to one. In this paper we discuss a model for the analysis of time–budgets that used this property. The model approximates the observed time–budgets by weighted sums of a number of latent time–budgets. These latent time–budgets determine the behavior of all objects. Special attention is given to the identification of the model. The model is compared with logcontrast principal component analysis.

Inmiddels is naar deze gevolgen veel onderzoek gedaan. Daarentegen is veel minderbekend over seksuele klachten, terwijl deze ook vaak voorkomen na een beroerte. In dit artikel zullen we een overzicht gevenvan de gevolgen van een beroerte voor de diverse fysieke, psychologische en sociale factoren gerelateerd aan seksualiteit.De seksuele problematiek is meervoudig van aard en verdient aandacht in al zijn facetten.

In this paper we argue for the importance ofstudying the positive influence of sanctioning systems on people’s moral convictions regarding the rule advocated bythe sanction and of studying factors that moderate this influence. In three experiments we tested the influence of sanctionseverity and showed that severe sanctions evoke stronger moral judgments with regard to rule-breaking behavior andstronger social disapproval towards rule-breakers than mild sanctions. This was particularly the case when trust inauthorities is high rather than low. Implications of these findings are discussed. Also, a framework is proposed tounderstand the possible circumstances that determine whether sanctions either increase or decrease moral norms.

From the early years of my own work in sex research, the ARSR has been one of my mostimportant resources. Its contributions always brought me comprehensiveness and scholarly excellence, whatever the topic of the article. Thus, it may not come as a surprise that I am dedicated to maintain this high standard of quality and comprehensiveness of the reviews that make it into ARSR. Below, I highlight some of the quality criteria that color my view of what are good and worthwhile review articles.<br/><br/>Description: Editorial Thu, 14 Jul 2011 14:53:00 GMT http://hdl.handle.net/1820/3427 Title: Herziening Besluit Psychotherapeut: kans voor sprong voorwaarts.<br/><br/>Authors: van Lankveld, Jacques; Arntz, Arnoud; Huibers, Marcus<br/><br/>Abstract: Het Besluit Psychotherapeut (bp) 1998 regelt de toegang tot het beroep van psychotherapeut in het big-register. Er klinken geluiden om de definitie van het beroep psychotherapeut opnieuw onder de loep te nemen via een herziening van het bp. Een herziening van dit besluit binnen afzienbare tijd is nuttig en noodzakelijk. De bijdrage van psychotherapieonderzoekers aan de herziening is essentieel, omdat de kwaliteitseisen moeten stoelen op onderzoeksgegevens over de werkzaamheid en kosten)effectiviteit van therapieën in plaats van op theoretische stromingen. Van herziening van het besluit valt een belangrijk effect op de praktijk van de psychotherapeutische hulpverlening te verwachten.

Gabriel and Odoroff (1984) suggested a resistant approach for lower rank approximation of matrices. In this approach, weights are used to diminish the influence of outliers on the low-dimensional representation. The present paper uses iterative majorization to provide for a general algorithm for such resistant lower rank approximations which guarantees convergence. It is shown that the weights can be chosen in different ways corresponding with different objective functions. Some possible extensions of the algorithm are discussed.

In this study, the effect of gender was investigated among 534 participants by means of a survey that was based on evolutionary adaptations underlying sexual behaviour, This survey the basis for a new research line. Analysis of covariance showed that, in general, men have a higher sex drive than women. These results are in line with studies of sexual selection and partner choice preferences where evolved behavioural manifestations of sex drive facilitate the competition and rivalry for access to a partner, and where men differ from women with regard to their participation in parental investment.

The role of procedural fairness<br/><br/>Authors: Verboon, Peter; van Dijke, Marius<br/><br/>Abstract: Building on theoretical notions that severe sanctions (more than mild ones) can communicatethat sanctioned behavior is morally unacceptable, we argued that particularly authoritieswho enact the sanction procedures in a fair manner stimulate compliance with theirdecisions. This is because such authorities should be considered legitimate to communicatewhat is morally acceptable and unacceptable. This interactive effect of sanction size andprocedural fairness on compliance should thus be mediated by moral evaluations of theauthority. A field survey and an experiment revealed support for these predictions. Theseresults thus support a non-instrumental perspective on the effectiveness of sanction severityin increasing compliance with authorities. Sun, 26 Sep 2010 00:00:00 GMT
