This study investigated the relationship between the development of students? self-regulated learning and students? perceptions of the learning environment in terms of autonomy support, the emphasis on relevance and collaborative learning. In addition, we compared innovative learning environments that aim to enhance self-regulated learning with traditional learning environments. Questionnaires for measuring self-regulated learning and perceptions of the learning environment were administered by 648 students. Self-regulated learning was measured at the start of secondary education and again half way through the first (...) year. The results point to the importance of how students perceive the learning environment for self-regulated learning. There was a positive relationship between autonomy support and relevance and self-regulated learning. Furthermore, students in innovative environments perceived more autonomy support, more emphasis on relevance and more collaborative learning than those in traditional environments. Students in innovative environments, however, reported no more self-regulated learning than students in traditional environments. (shrink)

To many in the Netherlands it seems that basic income’s time has come, following the wide appeal of several municipal experiments. These random-control trial designs study the effects on employment, social participation, health and well-being of exempting social assistance claimants from the duties of seeking work and participating in training activities under the workfare-oriented Participation Act. In some treatment groups, claimants also retain a larger percentage of earnings, thereby reducing the poverty trap. These two design features resemble an unconditional basic (...) income. I situate the experiments in the wider context of basic income and discuss their theoretical background and policy orientation. Under existing legal strictures, the experimental designs are too limited to judge the effects of replacing the conditional scheme of social assistance by an unconditional one. Yet these experiments point the way for future trials which can compare the effectiveness of basic income-oriented versus workfare-oriented treatments. (shrink)

This article challenges the general thesis that an unconditional basic income, set at the highest sustainable level, is required for maximizing the income-leisure opportunities of the least advantaged, when income varies according to the responsible factor of labor input. In a linear optimal taxation model (of a type suggested by Vandenbroucke 2001) in which opportunities depend only on individual productivity, adding the instrument of a uniform wage subsidy generates an array of undominated policies besides the basic income maximizing policy, including (...) a “zero basic income” policy which equalizes the post-tax wage rate. The choice among such undominated policies may be guided by distinct normative criteria which supplement the maximin objective in various ways. It is shown that most of these criteria will be compatible with, or actually select, the zero basic income policy and reject the basic income maximizing one. In view of the model's limited realism, the force of this main conclusion is discussed both in relation to Van Parijs' argument for basic income in Real Freedom for All (1995) and to some key empirical conditions in the real world.

It is often alleged that Cantor’s views about how the set theoretic universe as a whole should be considered are fundamentally unclear. In this article we argue that Cantor’s views on this subject, at least up until around 1896, are relatively clear, coherent, and interesting. We then go on to argue that Cantor’s views about the set theoretic universe as a whole have implications for theology that have hitherto not been sufficiently recognised. However, the theological implications in question, at least (...) as articulated here, would not have satisfied Cantor himself. (shrink)

In Anarchy, State, and Utopia, Robert Nozick contrasts entitlement theories of justice and “traditional” theories such as Rawls', utilitarianism or egalitarianism, and advocates the former against the latter. What exactly is an entitlement theory of justice? Nozick's book offers two distinct characterizations. On the one hand, he explicitly describes “the general outlines of the entitlement theory” as maintaining “that the holdings of a person are just if he is entitled to them by the principles of justice in acquisition and transfer, (...) or by the principle of rectification of injustice ”. On the other hand, his famous “Wilt Chamberlain” argument against alternative theories is first said to apply to “non-entitlement conceptions”, and later to any “end-state principle or distributional patterned principle of justice” — which amounts to an implicit characterization of an entitlement conception as a conception of justice which is neither end-state nor patterned.

Politiek gaat over het verenigen van gemeenschappelijke en conflicterende belangen in bindende collectieve besluitvorming op een wijze die door winnaars en verliezers kan worden aanvaard. In dit artikel baseer ik mij op het politiek gezaghebbende duurzaamheidsconcept van de Brundtlandcommissie in Our Common Future: ‘Duurzame ontwikkeling is ontwikkeling die tegemoetkomt aan de behoeften in het heden zonder de mogelijkheid van toekomstige generaties om te voorzien in hun eigen behoeften in de weg te staan’ . Dan blijkt direct dat het vinden van (...) principes voor een duurzame politiek lastig is, want het gaat hier om een morele eis rekening te houden met de belangen van mensen in komende generaties die nu nog geen deel uitmaken van een politieke gemeenschap.

Augmented Reality is itself a technology in which two ways of seeing are crossed. Our field of vision is thereby superimposed with digital information and images. But before this, the real environment is already perceived by machine seeing, it is redoubled by a 3D-model, scanned, located and linked. In this brief investigation, I will face the way of seeing in AR with traditional procedures, like ‘trompe-l'œil’ and the so-called ‘velo’, to distinguish between what remains classic and what has changed. It (...) is important to examine this as layering, because it is a very thin stack of techniques, technology, materials and media, we seek to watch through. Subsequently, I shall analyze a painting of the contemporary artist Laura Owens in which both ways are crossed, the traditional one and the one concerning AR. (shrink)

Spatial relations are central to geometrical thinking. With respect to the classical elementary geometry of Euclid’s Elements, a distinction between co-exact, or qualitative, and exact, or metric, spatial relations has recently been advanced as fundamental. We tested the universality of intuitions of these relations in a group of Senegalese and Dutch participants. Participants performed an odd-one-out task with stimuli that in all but one case display a particular spatial relation between geometric objects. As the exact/co-exact distinction is closely related to (...) Kosslyn’s categorical/coordinate distinction, a set of stimuli for testing all four types was used. Results suggest that intuitions of all spatial relations tested are universal. Yet, culture has an important effect on performance: Dutch participants outperformed Senegalese participants and stimulus layouts affect the categorical and coordinate processing in different ways for the two groups. Differences in level of education within the Senegalese participants did not affect performance. (shrink)

The cognitive processing of spatial relations in Euclidean diagrams is central to the diagram-based geometric practice of Euclid's Elements. In this study, we investigate this processing through two dichotomies among spatial relations—metric vs topological and exact vs co-exact—introduced by Manders in his seminal epistemological analysis of Euclid's geometric practice. To this end, we carried out a two-part experiment where participants were asked to judge spatial relations in Euclidean diagrams in a visual half field task design. In the first part, we (...) tested whether the processing of metric vs topological relations yielded the same hemispheric specialization as the processing of coordinate vs categorical relations. In the second part, we investigated the specific performance patterns for the processing of five pairs of exact/co-exact relations, where stimuli for the co-exact relations were divided into three categories depending on their distance from the exact case. Regarding the processing of metric vs topological relations, hemispheric differences were found for only a few of the stimuli used, which may indicate that other processing mechanisms might be at play. Regarding the processing of exact vs co-exact relations, results show that the level of agreement among participants in judging co-exact relations decreases with the distance from the exact case, and this for the five pairs of exact/co-exact relations tested. The philosophical implications of these empirical findings for the epistemological analysis of Euclid's diagram-based geometric practice are spelled out and discussed. (shrink)

In this paper, we give an axiomatization of the ordinal number system, in the style of Dedekind’s axiomatization of the natural number system. The latter is based on a structure $(N,0,s)$ consisting of a set N, a distinguished element $0\in N$ and a function $s\colon N\to N$. The structure in our axiomatization is a triple $(O,L,s)$, where O is a class, L is a class function defined on all s-closed ‘subsets’ of O, and s is a class function $s\colon O\to (...) O$. In fact, we develop the theory relative to a Grothendieck-style universe (minus the power set axiom), as a way of bringing the natural and the ordinal cases under one framework. We also establish a universal property for the ordinal number system, analogous to the well-known universal property for the natural number system. (shrink)

With technological possibilities in healthcare steadily increasing, more tools for digital cognitive rehabilitation become available. Acceptance of such technological advances is crucial for successful implementation. Therefore, we examined technology acceptance specifically for this form of rehabilitation in a sample of healthcare providers involved in cognitive rehabilitation. An adjusted version of the Technology Acceptance Model questionnaire was used, including the subscales for perceived usefulness, perceived ease of use, subjective norm, and intention to use, which all contribute to actual use of a (...) specific technology. Results indicate a generally favorable attitude toward the use of digital cognitive rehabilitation and positive responses toward the TAM constructs. Only for subjective norm, a neutral mean response was found, indicating that this could pose a potential obstacle toward implementation. Potential differences between subgroups of different age, gender, and professional background were assessed. Age and gender did not affect the attitude toward digital cognitive rehabilitation. Occupational therapists showed lower scores than healthcare psychologists and physiatrists with regard to perceived usefulness, possibly linked to a difference in operational and managerial tasks. The findings of his study stimulate further implementation of digital cognitive rehabilitation, where the role of subjective norms should be specifically considered. (shrink)

The next World Congress of Bioethics will be held in Doha, Qatar. Although this location provides opportunities to interact with a more culturally diverse audience, to advance dialogue between cultures and religions, offer opportunities for mutual learning, there are also huge moral concerns. Qatar is known for violations of human rights - including the treatment of migrant workers and the rights of women - corruption, criminalization of LGBTQI+ persons, and climate impact. Since these concerns are also key (bio)ethical concern we (...) call for a broad debate within the bioethics community whether organizing and attending the World Congress in Qatar is ethically problematic and how ethical concerns should be dealt with.

According to the logic of collective action, mere awareness of the causes of environmental degradation will not motivate rational agents to reduce pollution. Yet some government policies aim to enlist citizens in schemes of voluntary cooperation, drawing on an ethos of collective responsibility. Are such policies doomed to failure? This book provides a novel application of rational choice theory to a large-scale survey of environmental attitudes in The Netherlands. Its main findings are that rational citizens are motivated to cooperate towards (...) a less polluted environment to a large extent, but that their willingness to assume responsibility depends on the social context of the collective action problem they face. This empirical study is an important volume in the development of a more consistent foundation for rational choice theory in policy analysis, which seeks to clarify major theoretical issues concerning the role of moral commitment, self-interest and reciprocity in environmental behaviour.

Despite the reported limited success of conventional treatments and growing evidence of the effectiveness of adult bariatric surgery, weight loss operations for (morbidly) obese children and adolescents are still considered to be controversial by health care professionals and lay people alike. This paper describes an explorative, qualitative study involving obesity specialists, morbidly obese adolescents, and parents and identifies attitudes and normative beliefs regarding pediatric bariatric surgery. Views on the etiology of obesity—whether it should be considered primarily a medical condition or (...) more a psychosocial problem—seem to affect the specialists’ normative opinions concerning the acceptability of bariatric procedures as a treatment option, the parents’ feelings regarding both being able to influence their child’s health and their child being able to control their own condition, and the adolescents’ sense of competence and motivation for treatment. Moreover, parents and adolescents who saw obesity as something that they could influence themselves were more in favor of non-surgical treatment and vice versa. Conflicting attitudes and normative views—e.g., with regard to concepts of disease, personal influence on health, motivation, and the possibility of a careful informed consent procedure—play an important role in the acceptability of bariatric surgery for childhood obesity.
