Zande Logic and Western Logic’ Richard Jennings argues that contrary to the view of Evans-Pritchard and Tim Triplett the system of logic employed by the Azande is sui generis and distinct from that of Westerners. I argue that this thesis is erroneous because Jennings, following Evans-Pritchard, is at fault in his analysis of the logic of the Azande. Zande thinking on the topic of witchcraft-substance heritability is not contradictory as believed. But even if one assumes that the Azande do reason (...) contradictorily on matters of institutional importance, Jennings' thesis on the possibility of incompatible logics still fails because similar instances of contradictory thinking could be found in the West. Although in practical matters all peoples appeal to orthodox logic, in matters of institutional importance the epistemological relativist could be on fertile ground where orthodox logic is in conflict with beliefs that are institutionally grounded.

In this paper, we show that equation image is a equation image-conservative extension of BΣ1 + exp, thus it does not imply IΣ1.

In this paper, we introduce the systems ns-ACA₀ and ns-WKL₀ of non-standard second-order arithmetic in which we can formalize non-standard arguments in ACA₀ and WKL₀, respectively. Then, we give direct transformations from non-standard proofs in ns-ACA₀ or ns-WKL₀ into proofs in ACA₀ or WKL₀.

It is often emphasized that the Athenians viewed philosophy as essentially apolitical or anti-political. Placed in this context, Aristotle’s Politics 7.1–7.3 deserves special attention because here Aristotle presents his argument on the best life for ‘each human being and commonly for cities and human beings ’, which culminates in his conclusion that ‘the same life ’ is the best for them. This paper attempts to show that ‘the same life’ does not mean a life consisting of activity of the same (...) content but rather of the same type or kind, and that Aristotle semantically differentiates between ἑκάστῳ τε τῶν ἀνθρώπων and τοῖς ἀνθρώποις and assigns a sphere of philosophy to the former and a sphere of politics to the latter, which helps him mitigate the tension between the philosophical life and the political life.

have extremely harmful impacts on an individual’s physical, social and mental health throughout their life-span. Recently, it has been reported that maternal ACEs increase the risk of developmental delay in the offspring across generations. This mini review focuses on the direct relationship between maternal ACEs and child developmental delay, and potential mediators/moderators that associate their relationship. Six studies were identified using three search engines. The results indicated that four out of six studies reported at least one significant direct association between (...) maternal ACEs and child development. Additionally, maternal biological, psychological, and social factors were identified as mediators or moderators. In summary, we identified that maternal ACEs increased the risk of developmental delay in children via biological and psychosocial pathways. Future research should examine potential buffering factors and identify when it is crucial to break the intergenerational transmission. (shrink)

In prior research, signal detection theory has been widely utilized to assess metacognitive ability. However, the SDT metacognitive model requires the use of a two-alternative forced-choice task, while confidence must also be measured discretely. In our model, participants’ cognitive ability and their confidence in the cognitive task were used to estimate their metacognitive abilities. Therefore, in this study, a metacognitive model that can be applied to various cognitive tasks was developed. This model implements the item response theory and Q-learning models (...) to estimate cognitive ability; participants’ metacognitive ability is defined as the discrepancy between their confidence in their cognitive ability and their actual cognitive ability. The entire procedure was divided into two experiments. In experiment 1, two different cognitive tasks were used to estimate metacognitive ability and to examine overall discriminative and convergent validity. Notably, the parameters representing metacognitive ability did not correlate with cognitive ability but were positively correlated between the two tasks. In experiment 2, we performed a similar analysis using a different task to test the replicability of experiment 1. The results for experiment 2 were replicated for discriminative and convergent validity, albeit with weak results. Our metacognitive model exhibited high interpretability and versatility. (shrink)

Right-ear advantage refers to the observation that when two different speech stimuli are simultaneously presented to both ears, listeners report stimuli more correctly from the right ear than the left. It is assumed to result from prominent projection along the auditory pathways to the contralateral hemisphere and the dominance of the left auditory cortex for the perception of speech elements. Our study aimed to investigate the role of attention in the right-ear advantage. We recorded magnetoencephalography data while participants listened to (...) pairs of Japanese two-syllable words. The amplitudes of the stimuli were modulated at 35 Hz in one ear and 45 Hz in the other. Such frequency-tagging allowed the selective quantification of left and right auditory cortex responses to left and right ear stimuli. Behavioral tests confirmed the right-ear advantage, with higher accuracy for stimuli presented to the right ear than to the left. The amplitude of the auditory steady-state response was larger when attending to the stimuli compared to passive listening. We detected a correlation between the attention-related increase in the amplitude of the auditory steady-state response and the laterality index of behavioral accuracy. The right-ear advantage in the free-response dichotic listening was also found in neural activities in the left auditory cortex, suggesting that it was related to the allocation of attention to both ears.

This research is motivated by the program of reverse mathematics and non-standard arguments in second-order arithmetic. Within a weak subsystem of second-order arithmetic ACA0, we investigate some aspects of non-standard analysis related to sequential compactness. Then, using arguments of non-standard analysis, we show the equivalence of the Riemann mapping theorem and ACA0 over WKL0. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim).

This study examines values and value types as well as scores in levels of moral reasoning for␣students enrolled in a business program. These two factors are measured using the Schwartz Personal Values␣Questionnaire and the Defining Issues Test 2. No statistically significant differences in levels of moral␣reasoning, rankings of values, and value types could be attributed to gender. However, eight significant correlations between value types and levels of moral reasoning provide evidence that a systematic relationship exists. The relationships are not only (...) internally consistent but also consistent with the model of values based on motivational goals (Schwartz S. H. and K. Boenke: 2004, Journal of Research in Personality , 38 230–255). (shrink)

We investigate the reverse-mathematical status of several theorems to the effect that the natural number system is second-order categorical. One of our results is as follows. Define a system to be a triple A,i,f such that A is a set and i∈A and f:A→A. A subset X⊆A is said to be inductive if i∈X and ∀a ∈X). The system A,i,f is said to be inductive if the only inductive subset of A is A itself. Define a Peano system to be (...) an inductive system such that f is one-to-one and i∉the range of f. The standard example of a Peano system is N,0,S where N={0,1,2,…,n,…}=the set of natural numbers and S:N→N is given by S=n+1 for all n∈N. Consider the statement that all Peano systems are isomorphic to N,0,S. We prove that this statement is logically equivalent to WKL0 over RCA0⁎ source. From this and similar equivalences we draw some foundational/philosophical consequences. (shrink)

This research is motivated by the program of Reverse Mathematics. We investigate basic part of complex analysis within some weak subsystems of second order arithmetic, in order to determine what kind of set existence axioms are needed to prove theorems of basic analysis. We are especially concerned with Cauchy’s integral theorem. We show that a weak version of Cauchy’s integral theorem is proved in RCAo. Using this, we can prove that holomorphic functions are analytic in RCAo. On the other hand, (...) we show that a full version of Cauchy’s integral theorem cannot be proved in RCAo but is equivalent to weak König’s lemma over RCAo. (shrink)

The purpose of this paper is to present a commentary on the current state of contemporary African philosophy and to offer some criticisms and recommendations. The question concerning African philosophy has been debated for some years now and one has witnessed a number of interesting works on this topic.

This study uses the Schwartz Values Questionnaire and version 2 of the Defining Issues Test to investigate the values, value types (clusters of related values) and level of moral reasoning of a sample of 108 MBA students in a Canadian university. There are no statistically significant differences in the levels of moral reasoning attributed to gender. Male and female MBA students rank 'family security' and 'healthy' as their two most important values. For males, hedonism, achievement and self-direction are the three (...) most important value types, while for females they are benevolence, hedonism and security, respectively. There are statistically significant gender differences for the value types hedonism, achievement, stimulation and power. Overall, however, there are more similarities than differences between the male and the female students. Regression analysis indicates a statistically significant positive association between the postconventional level of moral reasoning as measured by P-scores and the value-type universalism. The findings provide further evidence that value types affect the postconventional level of moral reasoning. (shrink)

In this paper, we introduce a system of nonstandard second-order arithmetic $\mathsf{ns}$-$\mathsf{WWKL_0}$ which consists of $\mathsf{ns}$-$\mathsf{BASIC}$ plus Loeb measure property. Then we show that $\mathsf{ns}$-$\mathsf{WWKL_0}$ is a conservative extension of $\mathsf{WWKL_0}$ and we do Reverse Mathematics for this system.

Following Smaldino's definition, we claim that language is also an emergent group-level trait, and propose two facets to verify this statement, both of which also provide a general framework to address the future work about group-level traits.

This study examines the personal values and value types of Chinese accounting practitioners and students, using the values survey questionnaire developed and validated by Schwartz (1992, Advances in Experimental Social Psychology 25, 1–65). A total of 454 accounting practitioners and 126 graduate accounting students participated in the study. The results show that Healthy, Family Security, Self-Respect, and Honoring of Parents and Elders are the top four values for both accounting practitioners and accounting students, although these values are not ranked in (...) the same order. Social Power, An Exciting Life, Devout, and Accepting My Portion in Life are the lowest rated four values for the accounting practitioners whereas Devout, An Exciting Life, Detachment, and Accepting My Portion in Life form the bottom four values for the accounting students. Both accounting practitioners and students ranked Security as the highest value type and Tradition as the lowest one, and the students rated Self-Direction as significantly more important than the practitioners. With respect to gender differences, both the male accounting practitioners and students rated the value type Achievement significantly higher than their female counterparts and there were several significant gender differences in personal values for both accounting practitioners and students. In addition, the perceived values are linked to social and cultural factors as well as to the influence of Western values. (shrink)

In the fall of 1973, the mass Campaign to Criticize Lin Piao and Confucius started to develop. At the beginning, I was very nervous. I said to myself: "Oh no'. Prior to the Great Proletarian Cultural Revolution, I was always revering Confucius. Now that it is time to criticize Lin Piao and Confucius, I will once again become the object of criticism." Later, after further thought, I realized that this was not right; this thinking arose from my old standpoint, [the (...) one which had preceded the standpoint] of the Great Cultural Revolution. I had revered Confucius in the past, but that was because my former standpoint was reactionary and my line was wrong. I had already recognized this during the Cultural Revolution. On the issue of revering Confucius, I had already taken the first step in self-criticism too. Now, on the basis of criticism which I have already established, I will put forth more advanced criticism of Confucius and of my own earlier thinking on revering Confucius. With the revolutionary masses, I will criticize Lin Piao and Confucius. (shrink)

We examined amygdala subregion volumes in patients with a first episode of major depression and in healthy subjects. Covariate-adjusted linear regression was performed to compare the MD and healthy groups, and adjustments for age, gender, and total estimated intracranial volume showed no differences in amygdala subregion volumes between the healthy and MD groups. Within the MD group, we examined the association between amygdala subregion volume and the 17-item Hamilton Rating Scale for Depression score and the HAMD subscale score, and found (...) no association in the left amygdala. In the right amygdala, however, there was an inverse linear association between the HAMD total and the HAMD core and lateral nucleus and anterior-amygdaloid-regions. Furthermore, an inverse linear association was seen between the HAMD psychic and the lateral nucleus, anterior-amygdaloid-regions, transition, and whole amygdala. The findings of this study suggest that the severity of MD and some symptoms of MD are associated with right amygdala volume. There have been few reports on the relationship between MD and amygdala subregional volume, and further research is needed to accumulate more data for further validation. (shrink)

Given that care duties are central to the definition of motherhood across contexts, an extended separation from the woman’s family due to migration presents a major threat to her social identity as a mother and wife. Drawing on West and Zimmerman’s notion of “doing gender” and ethnographic research on Vietnamese low-waged contract workers in Taiwan, I provide vital insights into the discursive processes and everyday practices that underlie migrant women’s negotiations of motherhood and femininity. Specifically, I examine the various ways (...) migrant women perform and negotiate meanings of hy sinh and chịu đựng that are core values of Vietnamese womanhood. Combating the stigma of bad motherhood and failed femininity, I emphasize, is not just about reasserting one’s sense of gendered self but also about reassuring her access to the future support and care of the family. The study emphasizes intentionality and pragmatism in women’s social doings of gender and highlights moral dilemmas in gender politics. (shrink)

Terrence Kelly argues for a theory of practical rationality to explain and handle the issue of residential segregation in the United States. Kelly claims that theories of "racism as irrational" and rational choice are not explanatorily adequate in this regard. I argue that the theory of practical rationality is also not adequate because by allowing agents to offer accounts of their calculated behaviour, it allows little appraisal of the behaviour itself. I argue instead that better explanations could be offered by (...) appeal to ethical theory. Key Words: residential segregation • trust • practical rationality • ethical theory. (shrink)

Neoclassical economic theory in its pretensions to scientific status is founded on one of the variants of a now discredited positivism. Neoclassical economic theory claims that there are two distinct areas of economic research: positive economics and normative economics. The former is assumed to deal with the cognitive as scientific content of economics while the later focuses on welfare or equity issues. I argue that the reliance of the whole theoretical structure of economics on the normative postulate of rationality renders (...) neoclassical economics a normative discipline. I also argue that neoclassical economics should thus be viewed as an instance of applied ethics rather than as applied mathematics, say. Finally, it is suggested that neoclassical economics, if its scientific pretensions are to be taken seriously, should be absorbed theoretically into general anthropology. (shrink)

Kuhn's theory of scientific change is founded on the idea that there are minimal defensible grounds for the claim that the history of science is characterized by the cumulative growth of knowledge. According to Kuhn, revolutionary theories in the history of science cannot be perceived as logical and empirical derivations from their predecessors since, quite often, the research methods, theoretical assumptions and the empirical findings of the former are incompatible with the latter. Thus, the analysis of each novel scientific theory (...) must begin with a recognition of the epistemological and ontological independence of that theory's paradigm. (shrink)

The purpose of this study is to investigate the relationship between a firm’s strategy and consumers’ decisions in the presence of the paradox of choice and sharing personal information. The paradox of choice implies that having too many choices does not necessarily ensure happiness and sometimes having less is more. A new model is constructed introducing a factor of information sharing into the model of a previous study that embedded the paradox of choice only (Kinjo and Ebina in AI Soc (...) 30(2):291–297, 2015). A key feature of the model is its disutility function. It is demonstrated that if the sign of the cross derivative of the function is positive (negative) at the optimum, there is a positive (negative) correlation between the degree of sharing personal information chosen by the consumers and the number of products offered by the firm in its recommendation systems. It is also numerically indicated that the profit function of the firm becomes convex or concave depending on the shape of the disutility function. These results suggest that firms should carefully investigate the shape of the disutility function, under the paradox of choice and sharing personal information. (shrink)

An account of how the mathematical sciences turn the mind away from becoming and towards being. There are four main conclusions. 1. The study of numbers, when treated independently of the other sciences, uses a particular conception of the nature of numbers to detach the mind from the influence of perceptible objects. 2. The study of ratios and proportions, explicitly the core of Plato's harmonics, is fundamental also to plane and solid geometry and astronomy. 3. Ratios and proportion form the (...) basis for the synoptic vision of all the mathematical sciences. This vision is an essential preparation for dialectic because it makes mathematicians become aware of the limitations of the mathematics they have been engaged in but it also shows them how they can begin to overcome those limitations. 4. The main purpose of the study of numbers, treated finally in relation to the other sciences, is to calculate ratios. (shrink)

The purpose of our study is to investigate the effects of the number of products, product attributes, and prices on consumer confusion, conduct a numerical analysis to check the robustness of the results, and present an example of the cell phone market in Japan. Following an ideal point model and embedding the number of products and product attributes, we clarify how these factors affect consumer confusion and purchase probability. We show that as the number of product attributes increases, the choice (...) probability of each product becomes equal, implying that consumer confusion occurs. This result is robust to the introduction of prices as strategic variables. (shrink)

Real-world walking activity is important for poststroke patients because it leads to their participation in the community and physical activity. Walking activity may be related to adaptability to different surface conditions of the ground. The purpose of this study was to clarify whether walking adaptability on an uneven surface by step is related to daily walking activity in patients after stroke. We involved 14 patients who had hemiparesis after stroke and 12 healthy controls. The poststroke patients were categorized as least (...) limited community ambulators or unlimited ambulators. For the uneven surface, the study used an artificial grass surface. The subjects repeated even surface walking and the uneven surface walking trials at least two times at a comfortable speed. We collected spatiotemporal and kinematic gait parameters on both the even and uneven surfaces using a three-dimensional motion analysis system. After we measured gait, the subjects wore an accelerometer around the waist for at least 4 days. We measured the number of steps per day using the accelerometer to evaluate walking activity. Differences in gait parameters between the even and uneven surfaces were calculated to determine how the subjects adapted to an uneven surface while walking. We examined the association between the difference in parameter measurements between the two surface properties and walking activity. Walking activity significantly and positively correlated with the difference in paretic step length under the conditions of different surface properties in the poststroke patients and step width in the healthy controls. The strategy of increasing the paretic step length, but not step width, on an uneven surface may lead to a larger base of support, which maintains stability during gait on an uneven surface in poststroke patients, resulting in an increased walking activity. Therefore, in poststroke patients, an increase in paretic step length during gait on an uneven surface might be more essential for improving walking activity. (shrink)
