The effects of school inspections on school improvement have been investigated only to a limited degree. The investigation reported on in this article is meant to expand our knowledge base regarding the impact of school inspections on school improvement. The theoretical framework for this research is partly based on the policy theory behind the Dutch Educational School Supervision Act (the latter includes assumptions about how school inspections lead to school improvement). Interviews and a survey with school inspectors gave insight into (...) how school inspectors implement the Supervision Act and how they assess schools, and stimulate schools to improve. The results of ten case studies showed that all schools started to improve after a school visit. The innovation capacity of the school and the school environment do not seem to contribute to school improvement after school inspections. No effects were found on school-improvement processes of the number of insufficient scores that schools received from inspectors, the extent of feedback and suggestions for improvement, and the number of agreements. The provision of feedback about weaknesses, the assessment of these weak points as unsatisfactory, and the agreements between an inspector and the school regarding improvement activities do appear to make a difference in promoting school improvement.

This article describes a theory about the ambition of most Inspectorates to realise 'school improvement through inspection'. Literature about a number of direct and indirect interventions, such as reciprocity, communication and feedback is used to build a theoretical model stating the relations between working methods of school inspectors, reactions of schools and resulting effects and side effects. Finally two types of inspections strategies are described that can be used in different types of schools. We expect schools with a low innovation (...) capacity and few external impulses to be helped best by a directive approach in which an inspector clearly points to the strong and weak points of the school, the probable causes of their level of functioning, and potential ways for improvement. The inspector should pressure the school to change by making written agreements on how to change and by asking the school to work out these agreements in an improvement plan. A school with a high innovation capacity and strong external impulses is expected to do better with a more reserved inspection approach. Inspectors only need to provide this school with some insight into their strong and weak points. (shrink)

Animals depleting one patch of resources must decide when to leave and switch to a fresh patch. Foraging theory has predicted various decision mechanisms; which is best depends on environmental variation in patch quality. Previously we tested whether these mechanisms underlie human decision making when foraging for external resources; here we test whether humans behave similarly in a cognitive task seeking internally generated solutions. Subjects searched for meaningful words made from random letter sequences, and as their success rate declined, they (...) could opt to switch to a fresh sequence. As in the external foraging context, time since the previous success and the interval preceding it had a major influence on when subjects switched. Subjects also used the commonness of sequence letters as a proximal cue to patch quality that influenced when to switch. Contrary to optimality predictions, switching decisions were independent of whether sequences differed little or widely in quality. (shrink)

This study examined cancer patients’ perceived emotional and informational support from a variety of interpersonal and media sources. We recruited patients from cancer patient association websites and online cancer forums and asked them to report to what extent they received support from interpersonal and media sources. Patients rated professional sources and personal sources as nearly equal sources of emotional support; however, professional sources were rated as significantly greater sources of informational support. Although family and oncologists were the most mentioned interpersonal (...) sources of support, they were also the most mentioned disappointing sources. Of the media sources, online interaction sources were rated as nearly equivalent sources of emotional support as interpersonal sources. That patients perceived emotional support, not only informational support, from various media sources is promising since interpersonal sources can be disappointing to some patients. (shrink)

Socioemotional selectivity theory (SST), an influential life-span theory, suggests that older adults prefer persuasive messages that appeal to emotionally-meaningful goals over messages that appeal to knowledge-related goals, whereas younger adults do not show this preference. A mixed-factorial experiment was conducted to test whether older adults (≥65 years) differ from younger adults (25–45 years) in their preference for emotionally-meaningful appeals over knowledge-related appeals, when appeals are clearly developed in line with SST. For older adults we found the expected preference for emotionally-meaningful (...) appeals for cancer centers but not for grocery stores and travel organizations. As expected, in most cases, younger adults did not show a preference. Implications for SST-based communication research and for practice are discussed. (shrink)

The development of comparative biology has been of interest to philosophers and historians. Particular attention has been placed on the ‘war’ of the 1970s and 1980s, the apparent dispute among those who preferred this or that methodology. In this contribution we examine the history of comparative biology from the perspective of fundamentals rather than methodologies. Our examination is framed within the artificial—natural classification dichotomy, a viewpoint currently lost from view but worth resurrecting.

Bifurcation analysis of a real-time implementation of an ART network, which is functionally similar to the generalized localist model discussed in Page's manifesto shows that it yields a phase transition from local to distributed representation owing to continuous variation of the range of inhibitory connections. Hence there appears to be a qualitative dichotomy between local and distributed representations at the level of connectionistic networks conceived of as instances of nonlinear dynamical systems.

Generalization of the standard behavior longitudinal genetic factor model for the analysis of interindividual phenotypic variation to a genetic state space model for the analysis of intraindividual variation enables the possibility to estimate subject-specific heritabilities.

Cramer et al. present an original and interesting network perspective on comorbidity and contrast this perspective with a more traditional interpretation of comorbidity in terms of latent variable theory. My commentary focuses on the relationship between the two perspectives; that is, it aims to qualify the presumed contrast between interpretations in terms of networks and latent variables.

A new description of gravitational motion will be proposed. It is part of the proper time formulation of physics as presented on the IARD 2000 conference. According to this formulation the proper time of an object is taken as its fourth coordinate. As a consequence, one obtains a circular space–time diagram where distances are measured with the Euclidean metric. The relativistic factor turns out to be of simple goniometric origin. It further follows that the Lagrangian for gravitational dynamics does not (...) require an interpretation in terms of curvature of space–time. The flat space model for gravitational dynamics leads to the correct predictions for the bending of light, the perihelion shift of Mercury and gravitational red-shift. The new theory is free of singularities. More important, the new formulation of gravitational dynamics restores the validity of the principle of addition of potentials. One therefore can find solutions for static gravitational configurations for which it is difficult to find the solution of the corresponding Einstein equations. The method will be illustrated by means of the orbital precession for non-spherical stellar mass distributions. In case of the bipole mass distribution the agreement with the predictions of the general theory of relativity is very striking. Nevertheless, the new model is far more simple. (shrink)

Deficits in social cognition and more specifically in communication have an important impact on the real-life functioning of people with schizophrenia. In particular, patients have severe problems in communicative-pragmatics, for example, in correctly inferring the speaker’s communicative intention in everyday conversational interactions. This limit is associated with morphological and functional alteration of the left middle temporal gyrus, a cerebral area involved in various communicative processes, in particular in the distinction of ironic communicative intention from sincere and deceitful ones. We performed (...) an fMRI study on 20 patients with SZ and 20 matched healthy controls while performing a pragmatic task testing the comprehension of sincere, deceitful, and ironic communicative intentions. We considered the L-MTG as the region of interest. SZ patients showed difficulties in the correct comprehension of all types of communicative intentions and, when correctly answering to the task, they exhibited a higher activation of the L-MTG, as compared to HC, under all experimental conditions. This greater involvement of the L-MTG in the group of patients could depend on different factors, such as the increasing inferential effort required in correctly understanding the speaker’s communicative intentions, and the higher integrative semantic processes involved in sentence processing. Future studies with a larger sample size and functional connectivity analysis are needed to study deeper the specific role of the L-MTG in pragmatic processes in SZ, also in relation to other brain areas.

Bazzocchi disposes the text of the Tractatus in a user-friendly manner, exactly as Wittgenstein's decimals advise. This discloses the logical form of the book by distinct reading units, linked into a fashioned hierarchical tree. The text becomes much clearer and every reader can enjoy, finally, its formal and literary qualities.

Despite many reservations, Transition to an Ordinal Metaphysics is interesting because it continues a tradition which takes the metaphysical enterprise seriously, which attempts to examine the nature and function of metaphysics, and which attempts to communicate the insights and conceptual power of what Ross terms the ordinal approach to that enterprise.

This paper challenges T. S. Gendler's notion of aliefs, a novel kind of mental state which she introduces to explain a wide variety of belief-discordant behaviors. In particular, I argue that many of the cases which she uses to motivate such a mental state can be fully explained by accounts that make use only of commonplace attitudes such as beliefs and desires.

The optimal design of cables under selfweight and concentrated loads is considered and the maximum feasible span for a given permissible stress is evaluated. All solutions are obtained in a closed analytical form.

It has recently been argued that hope is polysemous in that it sometimes refers to hoping and other times to being hopeful. That it has these two distinct senses is reflected in the observation that a person can hope for an outcome without being hopeful that it will occur. Below, I offer a new argument for this distinction. My strategy is to show that accepting this distinction yields a rich account of two distinct ways in which hope can be lost, (...) ways that map onto the two senses of hope: A person can lose hope either by ceasing to hope for an outcome (hopelessness) or by ceasing to be hopeful that it will obtain (despair). Thinking about these negative attitudes in these two ways, I contend, is explanatorily rich and fruitfully reveals how they differ in phenomenology, behavioral differences, and the ways in which a person can escape them.
