We analyze the cognitive strategies underlying performance in the Number task, a Math game that requires both arithmetic fluency and mathematical creativity. In this game all elements in a set of numbers have to be used precisely once to create a target number with basic arithmetic operations. We argue that some instances of this game are NP complete, by showing its relation to the well-known Partition problem. We propose heuristics based on the distinction in forward and backward reasoning. The Number (...) Game is part of Math Garden, a popular online educational platform for practicing and monitoring math skills using innovations in computerized adaptive testing. These educational games generate enormous amounts of rich data on children's cognitive development. We found converging evidence for the use of forward proximity heuristics in the data of Math Garden, consisting of more than 20 million answers to 1,700 items. Item difficulties and the structure of correct answers were analyzed. (shrink)

The subtitle of this paper could have been, “Big Data meets Education to advance Cognitive Science.” In it, the authors analyze 20 million answers to 1700 simple arithmetic problems in an educational number game to determine “what makes some problems harder than others.” The results contribute to the cognitive science of arithmetic skill acquisition and have the potential to change how math is taught.

Religion is undergoing a transformation in current Western society. In addition to organized religions, there is a notable movement towards spirituality that is not associated with any institutions but in which experiences and notions of transcendence are still important. Transcendence can be described as God, the absolute, Mystery, the Other, the other as alterity, depending on one's worldview. In this book, these shifts in the views of transcendence in various areas of culture such as philosophy, theology, art, and politics are (...) explored on the basis of a fourfold heuristic model (proposed by Wessel Stoker)"--Back cover.

Some observers regard South Africa as one of the most violent, lawless and morally depraved societies in the world. Several other countries around the world can be shown to be similarly afflicted. In South Africa's case, this condition might be because of political transformation, particularly the lingering effects of the struggle against past injustices inflicted on sections of the population. The social instability has been exacerbated by an influx of migrants and a resultant increase in diversity. One way of attempting (...) to assuage this situation is to harness the school subject known as 'citizenship education' for guiding the upcoming generations into committing to a new moral compass, that is, awareness or consciousness with a conscience, and to an accompanying new social contract. Finding a rationale for such a moral compass and social contract that all the citizens of South Africa and of other similarly stricken countries would be prepared to commit to is a daunting task because people tend to be subjective in reflecting about their personal and group views, particularly about their religious beliefs and convictions. Closer examination reveals, however, that despite all the diversity, differences and conflict prevalent in societies, people are potentially able to share a set of basic values that arguably could form the core of the sought-for moral compass. Citizenship education could be functional in bringing home to the next generation the notion of henceforth living in accordance with the precepts of such a moral compass and social contract.

Synthetic biology is an emerging technology that asks for inclusive reflection on how people frame the field. To unravel how we can facilitate such reflection, this study evaluates the Frame Reflection Lab. Building upon playfulness design principles, the FRL comprises a workshop with video-narratives and co-creative group exercises. We studied how the FRL facilitated frame reflection by organizing workshops with various student groups. Analysis of 12 group conversations and 158 mini-exit surveys yielded patterns in first-order reflection as well as patterns (...) in second-order reflection. Also patterns in participants’ framing of synthetic biology could be induced; participants’ viewpoints converged to some extent, yet with openness to individual viewpoint differences. Although the FRL method fortified the reflection processes of participants, the narratives and the workshop’s flexible format could inhibit the reflection too. Therefore, we advise designers of future frame reflection methods to apply stronger conversational facilitation and narratives of slightly mysterious yet identifiable narrators, in case e.g. video-narratives are created and used to scaffold the reflection process. Nevertheless, we argue that the use of a playful frame reflection method like the FRL could function well as a step to precede more application-specific deliberation or decision-making on synthetic biology and as a method for the collection of contemporary citizen viewpoints plus rationales underlying these, for the further responsible development of the emerging field.

Welfare science has built its foundations on veterinary medicine and thus measures of health. Since bottlenose dolphins (Tursiops truncatus) tend to mask symptoms of poor health, management in captivity would benefit from advanced understanding on the links between health and behavioural parameters, and few studies exist on the topic. In this study, four representative behavioural and health measures were chosen: health status (as qualified by veterinarians), percentage of daily food eaten, occurrences of new rake marks (proxy measure of social activity), (...) and willingness to participate (WtP) in Positive Reinforcement Training sessions as qualitatively measured by their caretakers. These data were collected multiple times a day, every day over the course of a year from a multi-facility, large sample size (ndolphins= 51), allowing powerful analyses of the relationships between measures. First, it was found that dolphins with a higher WtP score also had a significantly better health status, ate a higher percentage of their daily food, and a lower occurrence of new rake marks. In addition, the WtP score was significantly lower up to 3 days before the weekly veterinary diagnosis of a decrease in health state; the percentage of daily food eaten and new rake mark measures did not show any significant change before such a diagnosis. These results suggest that WtP in training sessions is a potential behavioural measure of dolphin welfare, and an indicator of early changes in the dolphins’ health state. We therefore suggest measurement of WtP as a more practical and non-invasive tool to support veterinary care and general management. More work needs to be conducted to elucidate the influence of social behaviour on health, and to identify other potential welfare indicators, but this long-term study has shown that qualitative measures can be both practical and valid when assessing dolphin welfare.

Umuntu ngumuntu ngabantu is the Zulu version of a traditional African aphorism . Although with considerable loss of culture-specific meaning, it can be translated as: “A human being is a human being through other human beings.” Still, its meaning can be interpreted in various ways of which I would like to highlight only two, in accordance with the grammar of the central concept ‘Ubuntu’ which denotes both a state of being and one of becoming.Firstly, it can be interpreted as a (...) statement of fact about the human condition, i.e. as a descriptive claim about the social nature of human being and personal identity; even the constitutive relation between alterity and identity. Secondly, it can also be interpreted as a value-judgement, i.e. as a normative appreciation of social difference and human diversity; even as an imperative to expose ourselves to others, to encounter the difference of their humanness, in order to fully become our own. The meaning would then be — to paraphrase a translation of Ramose : To be human is to affirm one’s humanity by recognising the humanity of others in its infinite variety of content and form.CONCLUSION :The challenge of a philosophical understanding of the multi-cultural context of apartheid South Africa has still to be met. To meet this challenge is to try and trace the consequences of what it would mean if — to paraphrase Walzer — our crucial commonality is our particularity. Perhaps it will mean accepting that what we are and are becoming, our identity, escapes any reduction to the categories of the ‘self’ and the ‘other’ and eludes a dialectical ‘aufhebung’ of their difference. This may be the case if what we are and are becoming involves the paradox of being and becoming ever more different in the realisation of our self-sameness. Our African aphorism speaks of this paradox and, in so doing, it draws a limit to our philosophical understanding and provides us with a rule of conduct: Umuntu ngumuntu ngabantu! (shrink)

Optimism has reigned supreme for a long time regarding the potential of education (schooling) to address the many societal ailments that humankind has had to deal with. The outbreak of the COVID-19 pandemic in March 2020 shifted all such aspirations to the back-burner. Now, after just more than a year after the initial outbreak of the pandemic, the question can be raised whether those who managed the pandemic in the educational context followed the correct policies and instituted the correct (ethical, (...) moral) measures in combatting the pandemic. This comparison between the situation in the Netherlands and South Africa reveals that although the role-players in both countries had a good understanding of the situation and of their duties in such conditions, they tended to treat education as just another facet of society, thereby demonstrating a lack of empathy with the unique demands of education (schooling). CONTRIBUTION: In this article, the authors investigate the governance performance of two different countries during the first year of the COVID-19 pandemic concerning education and judge that performance based on a Biblically driven ethical-moral-pedagogical framework.

The European Clinical Trials Directive (EU 2001; 2001/20/EC) was introduced to improve the efficiency of commercial and academic clinical trials. Concerns have been raised by interested organizations and institutions regarding the potential for negative impact of the Directive on non-commercial European clinical research. Interested researchers within the European Group for Blood and Marrow Transplantation (EBMT) were surveyed to determine whether researcher experiences confirmed this view. Following a pilot study, an internet-based questionnaire was distributed to individuals in key research positions in (...) the European haemopoietic SCT community. Seventy-one usable questionnaires were returned from participants in different EU member states. The results indicate that the perceived impact of the European Clinical Trials Directive has been negative, at least in the research areas of interest to the EBMT. (shrink)

Academics and/or scholars increasingly feel that their academic voice (combined or individual) has been squelched by the demands of performativity in its various guises, and resultantly, that they have been caught up in a process of steady disempowerment. Rather, it should be their right to be free to use their positions in the pursuit of scholarship as their conscience and their expert knowledge of their subject dictate. Academics should be free to question for themselves the boundaries of their limitations, and (...) not have these i mposedon them by the state or government bureaucracy. In order to help empower academics to regain their academic voice and identity, this article transposes six of the philosophical ideas of Belgian philosopher Rudi Visker to the world of academia. It explores the possibilities of using these ideas as instruments for the promotion and maintenance of academic freedom. Key concepts: academic freedom, managerialism, institutions of higher learning, Rudi Visker. (shrink)
