Apahe Age Groups

Previous communications have indicated that interpretations of Rorschach protocols resultant from testing the Apaches of the Mescalero Indian Reservation produce information which conforms closely to that obtained by standard anthropological and psychoanalytic investigative techniques.

Anthropologic and psychoanalytic observations demonstrate that the effects of acculturation are less disruptive to the personality organization of old-age than of middle-age and young-age Mescalero and Chiracahua Apaches. In the present communication, a comparison is made of Rorschach protocols derived from testing of those three-age groups. The interpretation of those protocols confirms the assumptions based on the anthropological and psychoanalytic observations.     

Sexual socialization during early adolescence: the menarche

It has been shown that during adolescence most information about sexual matters, generally colored with misconceptions, comes from the peer group, since cultural inhibitions often prevent discussion with parents or other adults. In addition, there is abundant evidence from anthropological data of diffuse negative beliefs across cultures concerning menstruation. In order to explore the early socialization of beliefs and attitudes toward menarche, 258 adolescents, aged 11 to 14 years, male and female pre- and postmenarcheal, from southern Italy, were interviewed by way of an open questionnaire method. The results showed a consistent lack of accurate information by a high percentage of subjects, both male and female; negative beliefs were held only by girls, pre- and postmenarcheal, while boys were more likely to ignore the subject. Half of the postmenarcheal girls expressed a negative evaluation of their first experiences with menstruation, generally due to lack of advance information. As to sources of information, importance of the peer group was confirmed, especially for boys; the influence of the mother and the cultural environment accounted for the positive acceptance of menarche. Fathers appeared to be uninvolved in the transmission of information about menstruation to either boys or girls.     

Postmodern ontology,anthropology, and religion

This article analyses some changes produced in the contemporary ‘postmodern’ self and its consequences for the anthropological study of religion. In this regard, these changes influence deeply the way we westerners represent our ontological structure, and approach other religious systems and ontologies, due to the current processes of globalisation and transnationalisation, the notion of Self often fluctuates between an old stable, autonomous, maximiser (condensed) self and a dispersed, multivocal one. It is argued here that traditional anthropological analyses of religion lack this critical and reflexive awareness. For that reason, cultural phenomena such as shamanism, sorcery, and many forms of religious and cosmological syncretisms, are frequently approached from a distant, naturalistic viewpoint In this paper a more existential view of religion is proposed; it approaches the observer to the observed, opening up his/her assumptions about the ‘order of things’. A collection of notions, such as critical hermeneutics, critical intersubjectivity, dialectics, and ontological language is discussed, to build a fresh inquiry into the realms of numinous life.     

Muslims and the media in the blogosphere

In the past two decades a virtual Ummah has evolved in cyberspace. While some of these websites are targeted specifically at Muslims, others attempt to provide outreach on Islam or counter Islamophobic bias. As noted by Jon Anderson, in his pioneering work on Islam in cyberspace, Muslims were among the first engineering students to create websites at the dawn of the Internet, before mainstream Islamic organizations posted official websites. There is a wealth of material by Muslims in English and Western languages, some of it archived for research. This article explores the methodological problems posed in studying the range of Islam-content blogs, from private individuals to religious scholars, as well as Muslim websites that feature comments from readers. The focus of the paper is an analysis of blogs about Islam or by Muslims that either act as watchdogs on the media or try to provide alternative views to the mainstream media of competing Muslim groups. Researching these blogs as a form of e-ethnography calls for a rethinking and refining of anthropological methodology as e-ethnography.     

Local knowledge and comparative scientific traditions

This article argues that all knowledge is inherently local and that localness provides the basis for comparison between indigenous scientific traditions or knowledge production systems. As collective bodies of knowledge, many of the significant differences between knowledge production systems lie in the work involved in creating assemblages from differing practices. Much of the work can be seen in the social strategies and technical devices employed in creating equivalences and connections whereby otherwise heterogeneous and isolated knowledges are enabled to move in space and time from the local site and moment of their production and application to other places and times. In this way contemporary technosciences are compared with the knowledge systems of the medieval mastermasons, the Anasazi, the Inca, the Australian Aborigines and the Pacific navigators.     

Edgar Morin: From Vicious Circles to Virtuous Circles

Morin stresses the danger of the tendency to apply the method of natural sciences to human disciplines, considering the latter a natural object, and seeking one great explicative and definitive mathematical cosmological form by means of the reduction of the anthropological aspect to the biological one, of the biological to the physical–chemical aspect and the physical to the mathematical aspect. Hence the need to find a new way of organizing knowledge based on the concept of “circularity,” which is fundamental both in Morin's thought and in the philosophy of complexity in general. We must therefore establish a circular relation among the various spheres of knowledge: physics–biology–anthropology–sociology. The classical vision of a hierarchized-mechanic world is substituted by the vision of a reticulated world.     

Visual information about rigid and nonrigid motion: a geometric analysis

A mathematical analysis is presented that attempts to describe the available visual information about rigid and nonrigid motion and the three-dimensional structure of rigidly moving objects. Unlike other approaches, the analysis is based on the geometric relations among a set of trajectories defined over an extended region of space-time. Two experiments are reported in which observers viewed computer simulations of moving objects and were required to judge whether the observed motion appeared to be rigid or nonrigid. The results suggest that the mathematical limitations of a trajectory-based analysis of visual information are consistent with the perceptual limitations of actual human observers.     

不同类型数学任务的PASS认知加工发展特点

PASS理论是由Das和Naglieri提出的关于智力理论的一种认知过程理论。研究采用以PASS理论为基础编制而成的认知评估系统（第二版简版,CAS-2B）为研究工具,选取226名二年级、四年级以及七年级的学生,探讨PASS过程在数学计算流畅性,数学问题解决及数学推理等不同数学任务中的作用。研究结果显示：PASS模型各过程在三个年级的不同数学任务上各有侧重。在数学推理任务中,同时性加工对三个年级的数学推理任务预测显著,解释率为15%~17%,注意过程只在二年级对学生的数学推理任务预测;在数学计算流畅性任务中,注意过程随着年级的升高,其预测作用逐渐减退,解释率为5%~24%,计划功能的作用随年级的升高而逐渐突显;在数学问题解决任务中,继时性加工与注意功能对二年级预测显著,四年级时突显了计划和同时性加工的作用。不同复杂性的数学任务具有不同的认知特点,编码加工过程对于较复杂数学任务作用明显;计划与注意过程对简单数学任务作用明显。研究结果为今后不同年级学生开展有针对性的数学学习训练提供了理论基础。     

Death, Cadavers and Post-mortem Biomedical Research: A Point of View from a Christian Community

Facing modern developments of medicine and biomedical researches, religious communities are a strong source of ethics principles and orientations. Human dignity does not disappear after life, in a context of biomedical research on cadavers. Moral, political, social and scientific aspects of research on human cadavers (mainly autopsies) have been widely discussed in biomedical publications, whereas the religious ones (which could be predominant for some) have rarely been analyzed and presented. This article will present the results of a survey carried out a French Benedictine Abbey (relative to death, cadaver’s status and biomedical research) and subsequent Christian background according to canonic texts and practical cases from anthropological, historical, archeological and biomedical origin.     

THE TURKISH SEPHARDIM OF SAN ANTONIO MARKET,BARCELONA, 1900–1945

The article offers an historical anthropological study of a little-known, mostly Turkish-Sephardi population that settled in Barcelona at the beginning of the twentieth century, attracted by the commercial dynamism of the area around the San Antonio Market. The complete disappearance of the community in the early 1940s has made it more difficult to reconstruct its history than is the case with some other Jewish communities in Spain. Through oral history testimonies and the location of several dispersed sources, this article provides new ethnographic and historical information that contributes to recovering the memory of this Jewish community. The study is also an attempt to explain the reasons behind the departure of most of the community's members in the early 1940s, after more than 20 years of settlement and integration in the city of Barcelona. It shows how the new conditions introduced by the Francoist authorities had a direct impact on the ability of community members to make a living. The restrictions forced them first to ask for help from the international organizations which were helping European refugees and ultimately to leave the country.     

Geometry and generality in Frege's philosophy of arithmetic

This paper develops some respects in which the philosophy of mathematics can fruitfully be informed by mathematical practice, through examining Frege'sGrundlagen in its historical setting. The first sections of the paper are devoted to elaborating some aspects of nineteenth century mathematics which informed Frege's early work. (These events are of considerable philosophical significance even apart from the connection with Frege.) In the middle sections, some minor themes ofGrundlagen are developed: the relationship Frege envisions between arithmetic and geometry and the way in which the study of reasoning is to illuminate this. In the final section, it is argued that the sorts of issues Frege attempted to address concerning the character of mathematical reasoning are still in need of a satisfying answer.I am indebted to many people for helpful conversations and comments on this paper, notably Stephen Glaister, Phil Kremer, Madeline Larson, John McDowell, Jim Conant, Charles Chihara, William Craig, Jan Alnes, Joan Weiner, Leon Henkin, Paul Benacerraf, Juliet Floyd, Bill Demopoulos, Jose Ferreiros, Tom Hawkins, Gideon Rosen. Two superb papers on Frege — Bill Demopoulos' (1994) and Mark Wilson (1992) played a significant role in the early stages of composition.

Stereotype threat: the effect of expectancy on performance

The goal of this study was to investigate to role of expectancy as a potential mediator of performance deficits under stereotype threat. In Experiment 1, female students were assigned to one of three experimental conditions in which they were told that women perform worse (Negative information), equally (Control) or better (Positive information) than men in logical–mathematical tests. Later, they were given a difficult math test and asked to estimate their performance prior to taking the test. Consistent with predictions, participants who considered logical–mathematical abilities important and received negative information regarding the ingroup showed lower levels of expectations and a sharp decrease in performance compared to women in the positive and control conditions. Moreover, expectancy was found to partially mediate the effect of stereotype threat on performance. In Experiment 2, we tested the generalizability of these results to non‐stigmatized groups. A group of Black Americans living in Italy were provided with favorable or unfavorable information about either their minority (Blacks) or their majority (Americans) ingroup. Consistent with predictions, participants both in the minority and in the majority condition had lower expectations and under‐performed after negative information about the ingroup. However, the level of expectancy was found to mediate the decrease in performance for participants in the Black but not in the American condition. In the discussion of these results it is suggested that, although comparable performance deficits are found for minority and majority members, the underlying processes may be different.

On the status of proofs by contradiction in the seventeenth century

In this paper I show that proofs by contradiction were a serious problem in seventeenth century mathematics and philosophy. Their status was put into question and positive mathematical developments emerged from such reflections. I analyse how mathematics, logic, and epistemology are intertwined in the issue at hand. The mathematical part describes Cavalieri's and Guldin's mathematical programmes of providing a development of parts of geometry free of proofs by contradiction. The logical part shows how the traditional Aristotelean doctrine that perfect demonstrations are causal demonstrations influenced the reflection on proofs by contradiction. The main protagonist of this part is Wallis. Finally, I analyse some epistemological developments arising from the Cartesian tradition. In particular, I look at Arnauld's programme of providing an epistemologically motivated reformulation of Geometry free of proofs by contradiction. The conclusion explains in which sense these epistemological reflections can be compared with those informing contemporary intuitionism.     

Prediction of weightlifter’s motor behavior to evaluate snatch weightlifting techniques based on a new method of investigation of consumed energy

Using proper technique in different sports is an inevitable factor. In this study, available techniques for snatch weightlifting are mathematically evaluated. The optimal motion trajectory is a technique used by weightlifters, which could be determined based on minimizing specific object functions. Object functions based on total kinetic energy, total torque and total power and some new multiobjective functions are minimized using genetic algorithm and the minimax principle. Some important motion characteristics of 13 professional weightlifters were extracted and used to validate the mathematical results. The double knee bending (DKB) technique was studied as a benchmark test. Some important movement features of the technique were shown by the mathematical analysis when applying an object function, that minimized joint torques and powers of different muscles independently. An object function based on joint forces did not show these features.     

BODY, BRAIN, AND CULTURE

Abstract. Recent work in cerebral neurology should be used to fashion a new synthesis with anthropological studies. Beginning with Paul D. Madean's model of the triune brain, we explore Ralph Wendell Burhoe's question whether creative processes result from a coadaptation, perhaps in ritual itself, of genetic and cultural information. Then we examine the division of labor between right and left cerebral hemispheres and its implications for the notions of play and "ludic recombination." Intimately related to ritual, play may function in the social construction of reality analogous to mutation and variation in organic evolution. Finally, we consider how our picture of brain functioning accords with some distinctive features of the religious systems dominant in human cultures.     

Individual differences in working memory and reasoning-remembering relationships in solving class-inclusion problems

In the present experiment, we evaluated the effects of individual differences in reading span and variation in memory demands on class-inclusion performance. One hundred twenty college students whose reading spans ranged from low to medium to high (as indexed by a computerized version of the Daneman and Carpenter [1980] reading-span task) solved 48 class-inclusion problems. Half of the subjects had the solution information available when the problems were presented; the other half performed a detection task between solution information and problem presentation. The results from both standard statistical analyses and from a mathematical model indicated that differences in reading span and memory load had predictable, similar effects. Specifically, the sophistication of reasoning strategies declined when memory demands increased or when reading spans decreased. Surprisingly, these effects were primarily additive. The results were interpreted in terms of global resource models and findings from the developmental literature.
