A Computational Approach to Identifying Cultural Keywords Across Languages.

Distinctive aspects of a culture are often reflected in the meaning and usage of words in the language spoken by bearers of that culture. Keywords such as душа (soul) in Russian, hati (heart) in Indonesian and Malay, and gezellig (convivial/cosy/fun) in Dutch are held to be especially culturally revealing, and scholars have identified a number of such keywords using careful linguistic analyses (Peeters, 2020b; Wierzbicka, 1990). Because keywords are expected to have different statistical properties than related words in other languages, we argue that a quantitative comparison of word usage across languages can help to identify cultural keywords. To support this claim, we describe a computational method that compares word frequencies across languages, and apply it to both linguistic corpora and word association data. The method identifies culturally specific words that range from "obvious" examples, such as Amsterdam in Dutch, to non-obvious yet independently proposed examples, such as hati (heart) in Indonesian. We show in addition that linguistic corpora and word association data provide converging evidence about culturally specific words. Our results therefore show how computational analyses and behavioral experiments can supplement the methods previously used by linguists to identify culturally salient words across languages.

Measurement of maximum voluntary pinch strength: effects of forearm position and outcome score.

The purpose of this study was to determine the effects of forearm position and outcome score on key, fingertip, and three-jaw chuck pinch strength. Maximum voluntary key, fingertip, and three-jaw chuck pinches were performed by 135 healthy adults (20-88 years old) three times in a pronated, supinated, and neutral forearm position with the right and left hand using a B&L (B&L Engineering, Tustin, CA) pinch gauge. The highest, first, and mean scores of three pinch forces were recorded. Three 3 x 3 factorial repeated-measures analyses tested each type of pinch strength. Forearm position affected key and fingertip pinches (p<0.017; effect sizes <0.14) but not three-jaw chuck pinch. The highest score ranked highest followed by the first and then the mean of the three scores (p<0.017; effect sizes >0.53). Although the effects of type of outcome score were consistent, the statistically significant effects of forearm position and outcome score may be too small (<1 lb) to be clinically relevant. Standardized positioning during pinch strength measurement is still recommended despite these findings.
