Developmental effects of economic and educational change: Cognitive representation in three generations across 43 years in a Maya community

We studied the implications of social change for cognitive development in a Maya community in Chiapas, Mexico, over 43 years. The same procedures were used to collect data in 1969–1970, 1991, and 2012—once in each generation. The goal was to understand the implications of weaving, schooling and participation in a commercial economy for the development of visual pattern representation. In 2012, our participants consisted of 133 boys and girls descended from participants in the prior two generations. Procedures consisted of placing colored sticks in a wooden frame to make striped patterns, some familiar (Zinacantec woven patterns) and some novel (created by the investigators). Following Greenfield (2009), we hypothesised that the development of commerce and the expansion of formal schooling would influence children's representations. Her theory postulates that these factors move human development towards cognitive abstraction and skill in dealing with novelty. Furthermore, the theory posits that whatever sociodemographic variable is changing most rapidly functions as the primary motor for developmental change. From 1969 to 1991, the rapid development of a commercial economy drove visual representation in the hypothesised directions. From 1991 to 2012, the rapid expansion of schooling drove visual representation in the hypothesised directions.     

Changing the guard: Organizational science and social psychology in the US army

The US Army employed organizational and behavioral sciences in the context of the emerging Postindustrial political economy to shape its new strategic thought in the 1980s. This article examines how a group of military intellectuals in the Army applied ideas from these sciences to promote officer decision-making and decentralization while maintaining the Army's culture and ethics. They had significant reservations about bringing new ideas from the social sciences into the Army because Robert McNamara's modern cybernetic strategy had scarred the Army's morale and sense of self during the Vietnam War. Instead, the intellectuals carefully adapted ideas into the Army with an unsentimental attitude as it emerged from its post-Vietnam decline so it could fight complex maneuver warfare. Their strategic thought in the late Cold War made the Army a flexible global-spanning force for the unipolar moment in the 1990s and early 2000s.     

The interrelatedness between infants’ communicative gestures and lexicon size: A longitudinal study

Research has shown a close relationship between gestures and language development. In this study, we investigate the cross-lagged relationships between different types of gestures and two lexicon dimensions: number of words produced and comprehended. Information about gestures and lexical development was collected from 48 typically developing infants when these were aged 0;9, 1;0 and 1;3. The European Portuguese version of the MacArthur–Bates Communicative Development Inventory: Words and Gestures (PT CDI:WG) was used. The results indicated that the total number of actions and gestures and the number of early gestures produced at 0;9 and at 1;0 year predicted the number of words comprehended three months later. Actions and gestures’ predictive power of the number of words produced was limited to the 0;9–1;0 year interval. The opposite relationship was not found: word comprehension and production did not predict action and gestures three months later. These results highlight the importance of non-verbal communicative behavior in language development.     

Subjectivist – observing and objective – participant perspectives on the world: Kant,aquinas and quantum mechanics

Theological thinking is influenced by perspectives on the relation of scientific knowledge to reality. Two paradigms for understanding the nature of human knowledge are considered in relation to quantum mechanics: the subjective-observing perspective of Kant, and the objective-participant perspective of Thomas Aquinas. I discuss whether quantum mechanics necessarily implies a subject centered perspective on reality, and argue, with reference to d'Espagnat's notion of veiled reality, that quantum non-separability challenges this view. I then explore whether the objective-participant perspective of Thomas Aquinas provides a more fruitful context for understanding quantum mechanics. I discuss quantum measurement in terms of the transition from potentiality to actuality, and knowledge as the latent intelligibility of the world realized. However, the negative nature of our knowledge of quantum non-separability also challenges this perspective. Our theological thinking in response to quantum knowledge must therefore proceed tentatively, balancing a via positiva, with a via negativa.     

The body, adolescence, and psychosis

This article explores aspects of the clinical development of a male 17 year-old patient who had four weekly sessions of psychoanalysis during an acute psychotic crisis. In the context of arrested adolescent development, a psychotic crisis can present an opportunity to set the process of maturation in motion again. Adolescent psychosis is examined in the light of Bion's theories of catastrophic change - in which the container/contained relationship becomes explosive and overwhelming - as well as of Ferrari's and Matte Blanco's hypotheses on the mind-body relationship. The authors emphasize the role of denial of the body and its changes in the genesis of adolescent psychotic conflict, and show how the analytic relationship can offer crucial reverie conditions for promoting recognition of the body, bodily sensations and affects, as a prerequisite for the activation of an autonomous mental system. This clinical approach entails recognizing the urgent need to make room for the elaboration of intrasubjective relationships and for mind-body dialogue, transference interpretations being postponed. Clinical material and fragments of analytic dialogue illustrate the authors' hypotheses and demonstrate the patient's development towards recognition of his body and an incipient capacity to think associated with the perception of the limits set by time and reality.     

Is Obama the Anti-Christ? Racial priming, extreme criticisms of Barack Obama, and attitudes toward the 2008 US presidential candidates

This study investigated the impact of subtle racial priming on the persuasive impact of criticisms of Barack Obama in the month prior to the 2008 presidential election. To prime Black or White race, participants wrote a paragraph about a student with a typical Black or White name. They then read editorials that accused Obama of being unpatriotic or being the Anti-Christ, or that listed his positions on major issues. Participants responded to both criticisms with diminished preferences for and more negative beliefs about Obama, but only when African-American race was primed. Interestingly, the Anti-Christ criticism increased preferences and positive beliefs about Obama in the absence of racial priming, suggesting this criticism may have lacked credibility under neutral conditions.     

Continuum modeling of the reverse Hall–Petch effect in nanocrystalline metals under uniaxial tension: how many grains in a finite element model?

Owing to their very high strength, nanocrystalline metals have been extensively studied over the recent years. The direct Hall–Petch law, empirically proportioning the material strength to the inverse square root of its grain size has been shown to break down below a grain size of the order of tenths of nanometers. This phenomenon has been widely rationalized as a gradual switch from intragrain mediated deformation mechanisms to grain boundary mediated deformation mechanisms. This transition has been observed in many finite element simulations, despite the intrinsic restriction of necessarily limiting the nanocrystalline representative assembly to only a few grains. Such a limitation is generally overlooked, and its influence on an uniaxial tension test – when compared to a complete sample of millions of grains – ignored. We propose here to quantify the approximation done by considering a finite number of grains by means of a simple analytical model based on the early work of Stevens [R.N. Stevens, Philos. Mag. 23 (1971) p. 265]. The finite element approximation is demonstrated to be relatively good, even down to only three grains in width, and a method to “correct” the stress-strain curves of small representative volumes is proposed.     

Becoming a philosopher: What Heidegger learned from Dilthey, 1919–25

Wilhelm Dilthey is, famously, an epistemological pioneer for a second, ‘human’ kind of science that ‘understands’ life as we live it, instead of ‘explaining’ things as we observe them. Even today, he is usually cited for his role in the Erklären–Verstehen debate. My article, however, follows Heidegger's suggestion that we make the existence of the debate itself the problem. Whether there are different sorts of entity, different reasons for studying them and different means for doing so – such issues raise questions about science itself, not just about how to do it better. Moreover, what sort of philosopher is competent to address such questions? Heidegger argues that Dilthey's later writings intimate that it must be one who thinks from the ‘standpoint of (historical) life itself.’ This issue, says Heidegger, is ‘alive’ in Dilthey but is continually short-circuited by his very traditional plan for a ‘Critique of Historical Reason.’ Dilthey's unsuccessful struggles to produce this Critique are his gift to us, however. They encourage us to explicitly reconsider, as Heidegger does not only in Being and Time but throughout his life, what Dilthey cannot: If philosophy, like all human practices, is historical to the core, what is it to ‘be’ philosophical, about science or anything else?
