Whether any non-human animal can attribute mental states to others remains the subject of extensive debate. This despite the fact that several species have behaved as if they have a ‘theory of mind’ in various behavioral tasks. In this paper, we review the reasons of skeptics for their doubts: That existing experimental setups cannot distinguish between ‘mind readers’ and ‘behavior readers’, that results that seem to indicate ‘theory of mind’ may come from studies that are insufficiently controlled, and that our (...) own intuitive biases may lead us to interpret behavior more ‘cognitively’ than is necessary. The merits of each claim and suggested solution are weighed. The conclusion is that while it is true that existing setups cannot conclusively demonstrate ‘theory of mind’ in non-human animals, focusing on this fact is unlikely to be productive. Instead, the more interesting question is how sophisticated their social reasoning can be, whether it is about ‘unobservable inner experiences’ or not. Therefore, it is important to address concerns about the setup and interpretation of specific experiments. To alleviate the impact of intuitive biases, various strategies have been proposed in the literature. These include a deeper understanding of associative learning, a better knowledge of the limited ‘theory of mind’ humans actually use, and thinking of animal cognition in an embodied, embedded way; that is, being aware that constraints outside of the brain, and outside of the body, may naturally predispose individuals to produce behavior that looks smart without requiring complex cognition. To enable this kind of thinking, a powerful methodological tool is advocated: Computational modeling, namely agent-based modeling and, particularly, cognitive modeling. By explicitly simulating the rules and representations that underlie animal performance on specific tasks, it becomes much easier to look past one’s own biases and to see what cognitive processes might actually be occurring.

Empathy is often described as an evolutionary tool that helps humans manoeuvre between the complexities of our social hierarchy. As it allows us to understand other people's intentions, it is often categorized as an element of social cognition that can lead to a form of know-how. This paper will argue that empathy can lead to more than know-how. Using data from psychology and neuroscience, I will sketch empathizing as a reliable process. On the assumption of reliabilism, I will show that (...) empathizing as a generally reliable process can produce justified beliefs and thus that the empathizing process can lead to propositional knowledge. In passing I shall reveal some flaws in an influential line of research on empathy in psychology, which in turn exposes a more fundamental, conceptual, problem with empirical research on. (shrink)

This note is viewing survival data of a natural cohort as being generated by a possibly nonlinear, nonhomogeneous death process. It proves that the usual conditional distributions of the number of survivors at a certain age are binomial if and only if the death process is linear. Thus the customary statistical methods for the analysis of life table data are, strictly speaking, invalid whenever the underlying death process is nonlinear. For example, if a contagious disease is the cause of some (...) or all of the deaths, the deaths will not be independent and the death process, not linear. One should then base the statistical analysis on a model for the spread of the disease rather than the routine binomial model. (shrink)

ABSTRACTThis is the first study to investigate multiple cognitive biases in adolescence simultaneously, to examine whether anxiety and depression are associated with biases in attention and interpretation, and whether these biases are able to predict unique variance in self-reported levels of anxiety and depression. A total of 681 adolescents performed a Dot Probe Task, an Emotional Visual Search Task, and an Interpretation Recognition Task. Attention and interpretation biases were significantly correlated with anxiety. Mixed results were reported with regard to depression: (...) evidence was found for an interpretation bias, and for an attention bias as measured with the EVST but not with the DPT. Furthermore, interpretation and attention biases predicted unique variance in anxiety and depression scores. These results indicate that attention and interpretation biases are unique processes in anxiety and depression. They also suggest that anxiety and depression are partly based on similar underlying...

Because of the important role which the ‘autocatalytic’ or ‘logistic’ equation has played in determining the direction of a good deal of research both in demography and in the study of individual growth phenomena, a critical and comparative evaluation of those leading ideas inRobertson's book which pertain to this equation and of some of the criticisms levelled against it seemed to be of interest. The present paper shows that, contrary to common belief,Robertson did not really assume that the autocatalytic reactions (...) to which he compared growth processes, took place in closed systems . On the other hand, he does not seem to have found a satisfactory representation of how the growth phenomena of the individual cells in an organism might interact to yield the overall growth of the organism as a whole. Nor is the manner in which he made his equation account for the openness of the individual cells free from possible criticism. An alternative equation is here proposed, which will be discussed in another paper. The properties of the solutions of this equation are such that the autocatalytic theory might never have gained a foothold if this, more realistic, equation would have been the object of the initial studies.

This paper offers a conceptualmodel for participatory research projects thataim to improve the sustainability ofagriculture and natural resource management.The purpose of the model is to provide asystematic framework that can guide the designof participatory research projects, theiranalysis, and the documentation of results. Inthe model, conceptual boundaries are drawnbetween research and development, developmentand extension and between extension andimplementation. Objectives, activities, andactors associated with each of these realmsneed to be carefully selected, monitored, andevaluated throughout the course of a projectusing well-designed indicators. The (...) depth ofdisciplinary and methodological integration,and quality of participation needed to reachthe desired impact effectively and efficiently,however, needs to be determined on acase-by-case basis depending on the context andissues surrounding each particular project.

The disaggregation and geographic dispersion of global value chains (GVCs) have expanded the responsibility of international buyers from firm-level corporate social responsibility (CSR) towards social sustainability of their emerging country suppliers. We theorize, in this paper, that the effectiveness of lead firms’ GVC governance strategies for social sustainability—which can be audit-based or cooperation-based—depends on the local institutional context of the supplier. Supplier country institutions exert legal and civil society pressures for social sustainability, which shape suppliers’ attitude and receptiveness towards lead (...) firm requests. Using unique primary data from 356 garment and footwear suppliers in 11 emerging countries, which supply to Western European or North American buyers, we show that GVC governance strategies are particularly effective for suppliers’ social sustainability implementation when there is ‘contextual fit’ with local institutional pressures for social sustainability in the supplier country. Our study identifies the boundary conditions of GVC governance modes, and demonstrates a complementary relationship between organizational arrangements and their institutional-level counterparts in the context of social sustainability.

A commonly used experimental procedure for the study of granulocyte kinetics involves the labelling and subsequent tracing of granulocyte DNA. Following the introduction of a label into the system, observations are made periodically on the concentration of label in the DNA of granulocytes taken from the circulating blood. A mathematical model for the expected value of this concentration has been derived, studied, and related to experimental observations from studies using P32 as a label. Insofar as the derivation of the model (...) accurately incorporates the relevant aspects of granulocyte kinetics, the model will be useful in the interpretation of the experimental observations in terms of these kinetics.Among other things, study of the model indicates that the assumption of “flash” labelling made with respect to some labels is quite crucial and needs to be examined critically. It has also been necessary to make adjustments to allow for the observed emergence of labelled cells from the marrow soon after label introduction. In addition, despite a high degree of confounding of parameter effects it has been possible to suggest bounds on some of the parameters of the model for some species. The bounds will be refined as the model is improved and more data become available. Study and development of the model continues with particular interest in generalizations to include the diseased state chronic granulocytic leukemia. (shrink)

Investment in agricultural extension, as well as its design and practice, are usually based on the assumption that agricultural science generates technology (“applied science“), which extension experts transfer to “users“. This model negates local knowledge and creativity, ignores farmers' self-confidence and social energy as important sources of change, and, in its most linear expression, does not pay attention to information from and about farmers as a condition for anticipating utilization.In practice, farmers rely on knowledge developed by farmers, reinvent ideas brought (...) from outside and actively integrate them into complex farming decisions. Effective extension seems based on checks and balances that match intervention power with farmers' countervailing power, and mobilize farmers' creativity and participation in technology development and exchange.Alternative models for informing extension investment, design, and practice stress adult learning and its facilitation. The farmer is seen as an expert and farm development as driven by farmers' energy and communication. The article is a case study of a rare large scale attempt to use such an alternative model. It suggests that a shift to knowledgeintensive sustainable practices requires a learning process based on participation and empowerment. (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)

Ik kan de zeepokken niet vinden. Het is een warme zaterdagnamiddag in september, ik ben net aangekomen op het eiland en loop langs het water in de haven. Ik ben hier bijna twintig jaar niet geweest." In 'Vuurduin' gaat Eva Meijer een week naar Vlieland, op zoek naar wat verdwijnt. Het ecosysteem van de wadden staat onder druk, maar er liggen ook delen van haar eigen geschiedenis op het eiland, stukken tijd die nooit meer terugkomen. Alles verdwijnt natuurlijk: familie, geliefden, (...) huisdieren, gebeurtenissen. En de natuurlijke wereld laat ons zien dat dat erbij hoort - het is de stof waar we uit geweven zijn. Tegelijkertijd verdwijnt de levende wereld waarin dit alles ingebed is zelf in razende vaart: diersoorten sterven uit, ecosystemen gaan eraan, de permafrost smelt, onze winters worden herfst. Met behulp van schrijvers, filosofen, kunstenaars en hond Doris gaat Meijer op zoek naar de juiste woorden voor dit verlies, en voor wat we ertegenover kunnen zetten"--Page 4 of cover. (shrink)
