Exposed eye area (EEA) in the expression of various emotions.

Exposed eye area (EEA) was measured in photographs of Indian adults who modeled six emotions--happiness, sadness, fear, anger, surprise, and disgust--as well as a neutral expression. The data were analyzed with a 2 x 6 (Eyes x Emotions) factorial analysis of covariance (ANCOVA). EEA for neutral expression was used as the covariate measure. The EEAs of the two eyes did not differ significantly during the expression of emotion. The EEAs for fear and surprise were significantly larger, and the EEA for disgust was significantly smaller than those for either other emotions or neutral expression.     

Cross-cultural patterns in emotion recognition: highlighting design and analytical techniques

This article highlights a range of design and analytical tools for studying the cross-cultural communication of emotion using forced-choice experimental designs. American, Indian, and Japanese participants judged facial expressions from all 3 cultures. A factorial experimental design is used, balanced n x n across cultures, to separate "absolute" cultural differences from "relational" effects characterizing the relationship between the emotion expressor and perceiver. Use of a response bias correction is illustrated for the tendency to endorse particular multiple-choice categories more often than others. Treating response bias also as an opportunity to gain insight into attributional style, the authors examined similarities and differences in response patterns across cultural groups. Finally, the authors examined patterns in the errors or confusions that participants make during emotion recognition and documented strong similarity across cultures.     

Performance on a mirror-drawing task by non-right-handers

Left-, mixed-, and right-handed (each n = 10, N = 30) adolescent boys who were classified on the basis of a hand preference inventory performed a mirror-drawing task with a bilateral transfer of a skill paradigm. Participants' hand preference and the magnitude of bilateral transfer of skill were assessed in terms of errors committed and time taken to complete the mirror-drawing task. Mixed-handed participants exhibited significantly less habit interference for mirror drawing, and they performed the task significantly faster than the left-handers did; the group difference was not significant for the frequency of errors committed. These groups did not differ in terms of the magnitude of bilateral transfer of skill; the trend, however, showed that the transfer of skill was minimum in mixed-handers. These findings extend the theory that mixed-handed participants' inability to transfer motor skill from one hand to the other could be attributable to their lack of a clear pattern of lateralization. Their ability to perform well either at initial or later trials may be a function of less interference from their normal motor habits.     

Cultural Difference in Hand Preference: Evidence from India and Japan

Indian (N = 400) and Japanese (N = 502) adult subjects were examined for their hand preference on a 7-point scale (1 = left always, 7 = right always) of the 32-item Waterloo Handedness Questionnaire (Steenhuis & Bryden, 1989). Factor analyses of the data yielded a two-factorial structure of hand preference: skilled and unskilled. Interaction of Culture × Hand preference indicated that Indians had more right-hand preference for unskilled activities whereas Japanese subjects had more right-hand preference for skilled activities. Further analyses revealed that the frequency of middle category responses was more common in Japanese subjects. Indian subjects were found to give more extreme responses for either right- or left-hand preference. Findings are discussed in the light of cultural training given to the individuals in these two societies, which are essentially collective in nature.     

Twinning of quasicrystals and related structures

Abstract

We consider for the first time twinning in quasicrystals and related structures in a systematic manner. The twinning operations are considered in the framework of six-dimensional crystallography. The number of twin variants and the symmetry of twinned aggregates are also discussed. It is shown that essentially two different types of interface can arise between any two twin variants.     

Understanding the Factors Affecting the HIV Epidemic in Maharashtra: Application of Proximate Determinants Framework

The Indian HIV epidemic is exhibiting a declining trend, providing an opportunity for meta-analysis and data synthesis by triangulation to delineate the comprehensive picture and to understand the drivers of the epidemic. A proximate determinants (PD) framework is used to tease out factors affecting HIV vulnerability and to segregate the interplay of multiple factors operating within the framework. This study focuses on low-risk general males and high-risk male clients who form bridges between high-risk and low-risk populations. Data from NFHS-III, IBBA-1 and BSS have been used. The findings underscore multi-partner, condom use and partner-mixing as PD for general men, with coital frequency an additional determinant for clients. Partner type and number of lifetime partners are significant determinants for both groups. Significant underlying determinants, after adjustment for PDs, are younger age, marital status and alcohol for general men, and marital status, education, age at first intercourse and prior HIV testing for clients.     

Visual-field bias in the judgment of facial expression of emotion

The left and right hemispheres of the brain are differentially related to the processing of emotions. Although there is little doubt that the right hemisphere is relatively superior for processing negative emotions, controversy exists over the hemispheric role in the processing of positive emotions. Eighty right-handed normal male participants were examined for visual-field (left-right) differences in the perception of facial expressions of emotion. Facial composite (RR, LL) and hemifacial (R, L) sets depicting emotion expressions of happiness and sadness were prepared. Pairs of such photographs were presented bilaterally for 150 ms, and participants were asked to select the photographs that looked more expressive. A left visual-field superiority (a right-hemisphere function) was found for sad facial emotion. A hemispheric advantage in the perception of happy expression was not found.     

Tailoring the crack-tip microstructure: a novel approach

This investigation demonstrates a way to innovatively modify the ferritic microstructure at a local scale, particularly at the failure prone area such as Charpy V-notch (CVN) root. Tensile pre-strain (PS) up to 6% and 12% were employed before annealing (An) the samples at 650°C for 15?minutes. Ferrite grain size increased sharply and gradually (along the distance ahead of the notch root) within the microstructurally modified region in 6–12% pre-strained and annealed samples, respectively. The critical strain which promotes strain-induced boundary migration (SIBM), was found to be 0.1 which resulted in abnormally coarse ferrite grains.     

Degree of asymmetry in lateral preferences: eye, foot, ear.

Lateral asymmetry in eye, foot, and ear preference was measured using a 15-item questionnaire administered to 442 subjects. Degree and magnitude of asymmetry were greatest for eye, followed by foot and ear. Intercorrelations of lateral preferences were all positive and significant. Two primary factors, eyedness and earedness, were established.
