Theorising from the Global Standpoint: Kant and Grotius on Original Common Possession of the Earth

The paper contrasts Kant's conception of original common possession of the earth with Hugo Grotius's superficially similar notion. The aim is not only to elucidate how much Kant departs from his natural law predecessors—given that Grotius's needs‐based framework very much lines in with contemporary theorists’ tendency to reduce issues of global concern to questions of how to divide the world up, it also seeks to advocate Kant's global thinking as an alternative for current debates. Crucially, it is Kant's radical shift in perspective—from an Archimedean ’view from nowhere‘, to a first‐personal standpoint through which agents reflexively recognise their systematic interdependence in a world of limited space—that provides him with the more thorough and ultimately convincing global standpoint. This standpoint does not come with ready‐made solutions to shared global problems, but provides a promising perspective from which to theorise them.     

Quality of Life in Mexico: A Formative Measurement Approach

Improving quality of life for community members has become increasingly important for policy makers and society in general. This article presents the results from a representative sample of citizens from south-western Mexico. Because it is argued that quality of life indexes are formative rather than reflective, an advanced statistical method (partial least square) is used to analyze the data. The quality of life index used in the study includes the domains of health, income, work, education, safety, public services, non-governmental community services, social contact, and happiness. The results suggest that monetary-oriented indicators such as income and work are less important for respondents than domains such as happiness, social contact, or community services. However, for some of the domains, age and gender inequalities are observed.     

Two-digit number processing: holistic,decomposed or hybrid? A computational modelling approach

Currently, there are three competing theoretical accounts concerning the nature of two-digit number magnitude representation: a holistic, a strictly decomposed, and a hybrid model. Observation of the unit-decade compatibility effect (Nuerk et al. in Cognition 82:B25–B33, 2001) challenged the view of two-digit number magnitude to be represented as one integrated entity. However, at the moment there is no study distinguishing between the decomposed and the hybrid model. The present study addressed this issue using a computational modelling approach. Three network models complying with the constraints of all three theoretical models were programmed and trained on two-digit number comparison. Models were compared as to how well they accounted for empirical effects in the most parsimonious way. Generally, this evaluation indicated that the empirical data were simulated best by the strictly decomposed model. Implications of these results for our understanding of the nature of human number magnitude representation are discussed.     

Big brains are not enough: performance of three parrot species in the trap-tube paradigm

The trap-tube task has become a benchmark test for investigating physical causality in vertebrates. In this task, subjects have to retrieve food out of a horizontal tube using a tool and avoiding a trap hole in the tube. Great apes and corvids succeeded in this task. Parrots with relative brain volumes comparable to those of corvids and primates also demonstrate high cognitive abilities. We therefore tested macaws, a cockatoo, and keas on the trap-tube paradigm. All nine parrots failed to solve the task. In a simplified task, trap tubes with a slot inserted along the top were offered. The slot allowed the birds to move the reward directly with their bills. All but one individual solved this task by lifting the food over the trap. However, the parrots failed again when they were prevented from lifting the reward, although they anticipated that food will be lost when moved into the trap. We do not think that the demanding use of an external object is the main reason for the parrots’ failure. Moreover, we suppose these parrots fail to consider the trap’s position in the beginning of a trial and were not able to stop their behaviour and move the reward in the trap’s opposite direction.     

Caring for students: Pedagogy and professionalism in an age of anxiety

University teachers are strongly motivated by the care they feel for their students. Yet today, many are frustrated. On the one hand, it is becoming harder to teach well, as more diverse student populations, new media, and new educational priorities challenge conventional pedagogical postures and styles. On the other hand, teachers are wary of calls for greater pedagogical professionalism in an increasingly managed and de-motivating professional environment. This essay examines two movements in the United States that attempt to sustain teachers' motivation by rethinking what caring for students requires them to do. The first, a call for a “scholarship of teaching and learning,” directs the professor's attention outward, towards inquiry into their students' learning; the second directs attention inwards, encouraging exploration of “the inner landscape of a teacher's life.” While both movements oppose a narrow view of pedagogy as simply technique, they address the challenge of caring for students in different ways and point to resolutions that appear to have different potential to alter the teaching environment itself. These tensions around teaching inscribe in higher education wider debates about the value of the professions, the nature of expert practice, and how to recover and ensure professionals' capacity for care.     

Visual categorization of natural stimuli by domestic dogs

One of the fundamental issues in the study of animal cognition concerns categorization. Although domestic dogs (Canis familiaris) are on the brink to become one of the model animals in animal psychology, their categorization abilities are unknown. This is probably largely due to the absence of an adequate method for testing dogs’ ability to discriminate between large sets of pictures in the absence of human cueing. Here we present a computer-automated touch-screen testing procedure, which enabled us to test visual discrimination in dogs while social cueing was ruled out. Using a simultaneous discrimination procedure, we first trained dogs (N = 4) to differentiate between a set of dog pictures (N = 40) and an equally large set of landscape pictures. All subjects learned to discriminate between the two sets and showed successful transfer to novel pictures. Interestingly, presentation of pictures providing contradictive information (novel dog pictures mounted on familiar landscape pictures) did not disrupt performance, which suggests that the dogs made use of a category-based response rule with classification being coupled to category-relevant features (of the dog) rather than to item-specific features (of the background). We conclude that dogs are able to classify photographs of natural stimuli by means of a perceptual response rule using a newly established touch-screen procedure.
