Scholars have noted the need to examine the psychometric properties of measures that can be used in evaluating moral education programs. The present study was designed to examine the best?fitting factor model of a commonly?used measure of prosocial moral reasoning (PROM) across samples from Brazil and the USA, gender and adolescent age groups. The samples consisted of 619 college students (M age = 20.59 years, SD = 4.08; 41% men, 59% women) and 239 middle and high school students (M age (...) = 14.02 years, SD = 3.04; 45% boys, 55% girls) from the USA. There were 114 college students (M age = 21.81, SD = 4.33; 35% men, 65% women) and 136 middle and high school students (M age = 14.93 years, SD = 1.55; 42% boys, 58% girls) from Brazil. A series of (multigroup) confirmatory factor analyses were conducted to test the best fitting factor structure of the PROM and the invariance of this factor structure across culture, gender and age groups. Evidence for measurement invariance was found such that a four?factor model was a slightly better fitting model than the five?factor model across all groups. Discussion focuses on theoretical and methodological implications of the findings. (shrink)
This study examined relations between parenting dimensions (involvement, autonomy support and structure) and adolescents' moral values internalisation. A sample of 101 adolescents (71% female; 76% white; M age = 16.10, SD = 1.17) reported on the parenting behaviour of one of their parents and on their own moral values. Four forms of values regulation were assessed (external, introjected, identified and integrated), as well as overall internalisation. Structure was positively linked to external and introjected regulation, involvement was positively associated with identified (...) and integrated regulation and structure was negatively linked to overall internalisation. Additionally, positive interactions were found for autonomy support and involvement predicting identified and integrated regulation. Implications for parenting and moral education are discussed.

This study examined the hypothesis that religiosity would be differentially related to six types of adolescent prosocial behaviour, and that these relations would be mediated by the prosocial value of kindness. Self?report data were collected from 142 high school students (63 per cent female; 91 per cent White; M age?=?16.8, S?=?.80). Religiosity was a significant positive predictor of kindness, as well as compliant, anonymous and altruistic prosocial behaviour, but not public, dire and emotional prosocial behaviour. Associations between religiosity and both (...) compliant and altruistic prosocial behaviours were mediated by kindness. Direct and indirect paths were found between religiosity and anonymous prosocial behaviour. Thus, partial support was found for the mediational hypothesis. Discussion focused on the utility of distinguishing among different types of prosocial behaviours and on the role of religion and values in promoting moral education. (shrink)
There are three concerns regarding Rachlin's altruism model. First, proximal causal mechanisms such as those identified by cognitive neuroscientists and behavioral neuropharmacologists are not emphasized. Second, there is a lack of clear testable hypotheses. And third, extreme forms of altruism are emphasized rather than common forms. We focus on an overarching theme – proximal mechanisms of individual differences in altruism.
The necessary starting point in an analysis of Yugoslavia is the level of development of self-management. The 1973 law on collective work, the goal of which was to contain growing technocratic tendencies in the enterprises, has disciplined the powers of the “work units,” the democratic cells which are directed from below (in practice, they are something similar to department assemblies) and which were supposed to provide the most authentic foundation for self-management. These productive units can be compared to Western capitalist (...) firms whose goal, as we know, it to strengthen control over production costs, increase economic efficiency, facilitate management and create a more congenial atmosphere for work.

Today there is a great interest in reconstructing Lenin's thought concerning the relation between vangard and masses. Lenin's definitive theses on the problem are seen to have been outlined in his famous and much discussed work, What Is to Be Done? which, for some, remains the only scientific answer to the problem (not fully developed by Marx and Engels) of the passage from “class-in-itself” to “class-for-itself.” For others, this work, impregnated by intellectualism and idealism, is seen as a classic of (...) the Stalinist era and is held to be the root of all the bureaucratic deviations of the Soviet experience.

In this paper I present an argument against the feasibility of the Imitation Game as a test for thinking or language understanding. The argument is different from the five objections presented by Turing in his original paper, although it tries to maintain his original intention. I therefore call it “the Sixth Argument” or “the Argument from Context”. I show that – although the argument works against the original version of the imitation game – it may suggest a new version of (...) the Turing Test, still coherent with the idea of thinking and understanding as symbol manipulation. In a new form, the main idea which lies behind the original Imitation Game remains untouched by the criticism of Searle’s Chinese room argument and suggest a possible implementation which avoids some of the shortcomings of the original Turing Test.

Dieter Senghaas' recent volume on the problem of underdevelopment represents one of the few actual efforts in Western European culture of the last twenty years toward understanding the problem of underdevelopment from a progressive perspective. This exception is all the more relevant since it comes from a German scholar, i.e., an exponent of a scientific climate which is definitely conservative and often openly reactionary. Starting from the empirical discovery of the existence of an unbalanced social division of labor in the (...) world market (pp. 15 and 25), Senghaas is led to the repudiation of the Ricardian law of comparative costs and benefits (p. 27ff).

In the 1960s molecular population geneticists used Monte Carlo experiments to evaluate particular diffusion equation models. In this paper I examine the nature of this comparative evaluation and argue for three claims: first, Monte Carlo experiments are genuine experiments: second, Monte Carlo experiments can provide an important meansfor evaluating the adequacy of highly idealized theoretical models; and, third, the evaluation of the computational adequacy of a diffusion model with Monte Carlo experiments is significantlydifferent from the evaluation (...) of the emperical adequacy of the same diffusion model.

Exploring how people represent natural categories is a key step toward developing a better understanding of how people learn, form memories, and make decisions. Much research on categorization has focused on artificial categories that are created in the laboratory, since studying natural categories defined on high-dimensional stimuli such as images is methodologically challenging. Recent work has produced methods for identifying these representations from observed behavior, such as reverse correlation (RC). We compare RC against an alternative method for inferring the structure (...) of natural categories called Markov chain Monte Carlo with People (MCMCP). Based on an algorithm used in computer science and statistics, MCMCP provides a way to sample from the set of stimuli associated with a natural category. We apply MCMCP and RC to the problem of recovering natural categories that correspond to two kinds of facial affect (happy and sad) from realistic images of faces. Our results show that MCMCP requires fewer trials to obtain a higher quality estimate of people’s mental representations of these two categories. (shrink)
I never met Gian-Carlo Rota but I have often made references to his writings on the philosophy of mathematics, sometimes agreeing, sometimes disagreeing. In this paper I will discuss his views concerning four questions: the existence of mathematical objects, definition in mathematics, the notion of proof, the relation of philosophy of mathematics to mathematics.
The article is the consequence of some critical notes to the contribution of Paolo Bellan, arising from reading of essays of Francesco Emmolo and Carlo Sini and the assumption of a purely phenomenological perspective in the interpretation of the processes of acquisition of scientific knowledge.
This paper reviews and enhances numerical models for determining thermal, elastic and electrical properties of carbon nanotube-reinforced polymer composites. For the determination of the effective stress–strain curve and thermal conductivity of the composite material, finite-element analysis (FEA), in conjunction with the embedded fibre method (EFM), is used. Variable nanotube geometry, alignment and waviness are taken into account. First, a random morphology of a user-defined volume fraction of nanotubes is generated, and their properties are incorporated into the polymer matrix using the (...) EFM. Next, incremental and iterative FEA approaches are used for the determination of the nonlinear properties of the nanocomposite. For the determination of the electrical properties, a spanning network identification algorithm is used. First, a realistic nanotube morphology is generated from input parameters defined by the user. The spanning network algorithm then determines the connectivity between nanotubes in a representative volume element. Then, interconnected nanotube networks are converted to equivalent resistor circuits. Finally, Kirchhoff's current law is used in conjunction with FEA to solve for the voltages and currents in the system and thus calculate the effective electrical conductivity of the nanocomposite. The model accounts for electrical transport mechanisms such as electron hopping and simultaneously calculates percolation probability, identifies the backbone and determines the effective conductivity. Monte Carlo analysis of 500 random microstructures is performed to capture the stochastic nature of the fibre generation and to derive statistically reliable results. The models are validated by comparison with various experimental datasets reported in the recent literature. (shrink)
Monte Carlo simulations arrive at their results by introducing randomness, sometimes derived from a physical randomizing device. Nonetheless, we argue, they open no new epistemic channels beyond that already employed by traditional simulations: the inference by ordinary argumentation of conclusions from assumptions built into the simulations. We show that Monte Carlo simulations cannot produce knowledge other than by inference, and that they resemble other computer simulations in the manner in which they derive their conclusions. Simple examples of Monte (...)Carlo simulations are analysed to identify the underlying inferences. (shrink)
Shaftesbury señala la belleza de la teoría matemática y le asigna relevancia en el despliegue y en la estructura misma del pensamiento. Esta nota considera a la vez dicha reflexión y los asertos del matemático Gian-Carlo Rota acerca de tópicos análogos e intenta dilucidar, dentro de lo posible, ambas intuiciones.
The essay examines both the dances and the dance notation of renowned nineteenth century choreographer Carlo Blasis. It looks in detail at Blasis major treatise The Code of Terpsichore in an effort to evaluate how Blasis linked a science of movement to a conception of the body oriented around the prevailing aesthetics informing all of the fine arts. Identifying Blasis as both a philosopher and a mechanist, this essay analyzes his approach to teaching basic ballet vocabulary, and in particular (...) the arabesque. Whereas Kleist, with his Marionettentheater, proposes the puppet as a figure of grace, located somewhere between animal and doll, Blasis brings together the movement science of mechanics and the descriptive theory of grace (as mimesis) in a poetics of the arabesque, a synthesis of elevation and evanescence, which we see when we conjure up pictures of nineteenth century Romantic ballet.

The majority of literature on Slow Food focuses on the organization or actors involved in the movement. There is a dearth of material analyzing Carlo Petrini’s aspirations for Slow Food, particularly in light of his desire within Slow Food Nation (2007) and Terra Madre (2010) to make “freewill giving a part of economic discourse.” This essay corrects the literature gap through historicizing and critiquing Petrini’s alternative to global capitalism while rooting it in actually existing practices. First, Petrini’s problematic conceptualization (...) of freewill giving will be compared to feminist theorizations and documentations of the gift economy. Second, Petrini’s avoidance of the toxic mimic of the gift, its subsumption to capitalism, will be amended by discussing how the gifting of food aid and emergency food networks actually reproduces inequality, poverty, and hunger. Third, Petrini’s example of gifting by a Trappist Monastery will be juxtaposed to the ongoing direct action strategies of Food Not Bombs, a much stronger example of an oppositional gift economy, one that is subsequently repressed by the state. In doing so, this essay seeks to expand discussion of the gift economy within the alternative food movement while amending many of the theoretical, historical, and political problems embedded within Petrini’s work, which performs a strong disservice to the politics of possibility embedded within gifting.

Carlo Rovelli's relational interpretation of quantum mechanics holds that a system's states or the values of its physical quantities as normally conceived only exist relative to a cut between a system and an observer or measuring instrument. Furthermore, on Rovelli's account, the appearance of determinate observations from pure quantum superpositions happens only relative to the interaction of the system and observer. Jeffrey Barrett () has pointed out that certain relational interpretations suffer from what we might call the ‘determinacy problem', (...) but Barrett misclassifies Rovelli's interpretation by lumping it in with Mermin's view, as Rovelli's view is quite different and has resources to escape the particular criticisms that Barrett makes of Mermin's view. Rovelli's interpretation still leaves us with a paradox having to do with the determinacy of measurement outcomes, which can be accepted only if we are willing to give up on certain elements of the ‘absolute’ view of the world.
