AbstractThe representation of the metrics of the hands is distorted, but is susceptible to malleability due to expert dexterity (magicians) and long-term tool use (baseball players). However, it remains unclear whether modulation leads to a stable representation of the hand that is adopted in every circumstance, or whether the modulation is closely linked to the spatial context where the expertise occurs. To this aim, a group of 10 experienced Sign Language (SL) interpreters were recruited to study the selective influence of expertise and space localisation in the metric representation of hands. Experiment 1 explored differences in hands’ size representation between the SL interpreters and 10 age-matched controls in near-reaching (Condition 1) and far-reaching space (Condition 2), using the localisation task. SL interpreters presented reduced hand size in near-reaching condition, with characteristic underestimation of finger lengths, and reduced overestimation of hands and wrists widths in comparison with controls. This difference was lost in far-reaching space, confirming the effect of expertise on hand representations is closely linked to the spatial context where an action is performed. As SL interpreters are also experts in the use of their face with communication purposes, the effects of expertise in the metrics of the face were also studied (Experiment 2). SL interpreters were more accurate than controls, with overall reduction of width overestimation. Overall, expertise modifies the representation of relevant body parts in a specific and context-dependent manner. Hence, different representations of the same body part can coexist simultaneously.

Background: This study aims to test the hypothesis that: (1) radiation exposure is increased with the intended use of Flat Surface Image Intensifier (FSII) units above the operative surface compared with the traditional below-table configuration; (2) this differential increases in a dose-dependent manner; and (3) radiation exposure varies with body part and proximity to the radiation source. Methods: A surgeon mannequin was seated at a radiolucent hand table, positioned for volar distal radius plating. Thermoluminescent dosimeters measured exposure to the eyes, thyroid, chest, hand, and groin, for 1- and 15-minute trials from a mini C-arm FSII unit positioned above and below the operating surface. Background radiation was measured by control dosimeters placed within the operating theater. Results: At 1-minute of exposure, hand and eye dosages were significantly greater with the flat detector positioned above the table. At 15-minutes of exposure, hand radiation dosage exceeded that of all other anatomic sites with the FSII in both positions. Hand exposure was increased in a dose-dependent manner with the flat detector in either position, whereas groin exposure saw a dose-dependent only with the flat detector beneath the operating table. Conclusions: These findings suggest that the surgeon’s hands and eyes may incur greater radiation exposure compared with other body parts, during routine mini C-arm FSII utilization in its intended position above the operating table. The clinical impact of these findings remains unclear, and future long-term radiation safety investigation is warranted. Surgeons should take precautions to protect critical body parts, particularly when using FSII technology above the operating with prolonged exposure time.

The study aimed to identify swearing using body parts in the Jordanian setting as a social phenomenon used by male university students. The corpus of the study included (100) male university students. A socio-pragmatic approach was adopted to analyze the data. The study employed Simak Libat Cakap technique in addition to the qualitative method to analyze the data of the study. The analysis of data showed that the face was the most frequent body part used in swearing followed by the head. The main findings revealed that swearing is dominantly used to express a socio-pragmatic function of angriness, especially when swearers feel angry with their disputers. Swearing functions as a vehicle for releasing tension and anger and proved to be powerful in exchanging insults. The study concluded that swearers usually do not mean what they say. Swearing mostly includes non-literal meanings like idioms. Therefore, it should not be interpreted literally; otherwise, it will lose its connotative meaning.

Abstract The human body is central to myriad metaphors, so studying the conceptualisation of the body itself is critical if we are to understand its broader use. One essential but understudied issue is whether languages differ in which body parts they single out for naming. This paper takes a multi-method approach to investigate body part nomenclature within a single language family. Using both a naming task (Study 1) and colouring-in task (Study 2) to collect data from six Japonic languages, we found that lexical similarity for body part terminology was notably differentiated within Japonic, and similar variation was evident in semantics too. Novel application of cluster analysis on naming data revealed a relatively flat hierarchical structure for parts of the face, whereas parts of the body were organised with deeper hierarchical structure. The colouring data revealed that bounded parts show more stability across languages than unbounded parts. Overall, the data reveal there is not a single universal conceptualisation of the body as is often assumed, and that in-depth, multi-method explorations of under-studied languages are urgently required.

<p>Levin and Rappaport Hovav (1995) remind us that manner and result verbs often exhibit complementary distribution within a given language. They also note that when a main verb lexically specifies manner or result, the complementary component can be expressed outside the verb, in a satellite constituent of some sort. In Rappaport Hovav and Levin (2010), manner/result complementarity constrains verb root lexicalization. Building on this, Erteschik-Shir and Rapoport (2010) examine English verbs of contact, e.g. <em>smear</em>, <em>splash</em>, whose complements specify a result relation between moveable object and stationary locatum. Classically, these verbs show a locative alternation with holistic ~ partitive interpretations (Levin 1993).</p><p>For this paper I examine forceful contact expressions in Emai (West Benue Congo, Edoid in Williamson and Blench 2000). Relatively strict SVO, Emai manifests little inflectional morphology and few prepositions. Its motion predications express manner and result as one verb in series with another (<em>la</em> ‘run’ and <em>shan</em> ‘move through’ for ‘run through’) or as verb plus postverbal particle (<em>si<span style="text-decoration: underline;">o</span>n</em> ‘thread’ and <em><span style="text-decoration: underline;">o</span></em> ‘onto’ for ‘thread onto’).</p><p>Lacking verbs in series or postverbal particles, forceful contact in Emai reflects simple and complex predications. Predicates like transitive <em>hian</em> ‘strike’ or <em>so</em> ‘collide, bang into’ take a subject expressing moveable object and a direct object conveying locatum (<em>òjè só ùdék<span style="text-decoration: underline;">è</span>n</em> [Oje collide wall] ‘Oje collided with / banged into the wall’).</p><p>Related complex predications explicitly code contact means. English near equivalents are ‘punch,’ ‘kick,’ ‘peck,’ ‘bite’ and ‘pinch.’ Corresponding Emai predications with <em>hian</em> or <em>so</em> require means of contact, expressed as a body-part noun (<em>èkpà</em> ‘fist,’ <em>ízà</em> ‘heel,’ <em>úkpà </em>‘beak,’ <em>àk<span style="text-decoration: underline;">ò</span>n</em> ‘tooth,’ <em>éhì<span style="text-decoration: underline;">é</span>n</em> ‘fingernail’) covertly linked to a subject referent, followed by a preposition marked locatum. With a nonhuman locatum, body-part means (serving as moveable object) occurs in direct object position and a place noun locatum appears as preposition <em>vbi</em> object (<em>òhí só ékpá vbì ìtébù</em> [Ohi collide fist LOC table] ‘Ohi’s fist collided with the table/ Ohi’s fist banged on the table’). With a human locatum, the means body-part nominal is retained but a distinct body-part noun occurs as <em>vbi</em> object and its external possessor immediately follows the verb and precedes the moveable object (<em>òhí só ójé ékpá vbì <span style="text-decoration: underline;">è</span>ò</em> [Ohi collide Oje fist LOC face] ‘Ohi’s fist collided with Oje’s face / Ohi punched Oje in the face’).  Human locatum predications also show an alternation lacking the <em>vbi</em> phrase (<em>òhí só ójé èkpà</em> [Ohi collide Oje fist] ‘Ohi’s fist collided with Oje / Ohi punched Oje’). There is however no simple transitive predication that combines as core arguments possessors, with or without their body parts (*<em>òhí só òjè</em> ‘Ohi punched Oje’), or subject possessor and locatum (*<em>òhí só ùdék<span style="text-decoration: underline;">è</span>n</em> ‘Ohi punched the door’). As a consequence, result is privileged in Emai expression of forceful contact, downgrading manner through use of nominal forms and their partitive relations. English, as manner prominent in this domain, reveals a contrary type, where manner is obligatorily verb expressed (<em>punch</em>) and result is optionally available via prepositional satellite (<em>on</em>). </p>

AbstractThere are six different terms to refer to the ‘face’ in Buryat. The aim of the present paper is to clarify the difference in the usage of all these various terms: which one is used as a body part anatomically, which one is used mostly with metaphorical meanings, which one has a common meaning as appearance, or whether all of them are used equally in all categories. The terms are explored from etymological, semantic and morphological aspects.

AbstractThe skin of persons with atopic dermatitis (AD) is very susceptible to cutaneous infection, and some yeast species may also aggravate AD. The total yeast population of an AD patient’s skin and its relation with individual age and body part remains poorly characterized. The aim of this study was to clarify the differences in cutaneous yeast flora by age and body parts of AD patients.By swabbing affected body parts (hands, legs, face, neck or trunk), 241 samples were collected from patients with AD (132 children and 109 adults), and as controls, 40 samples were taken from healthy individuals (20 children, 20 adults).In all, 89 (36.9%) of samples were positive; the yeast isolated belonged to three genera: Candida (27.4%), Malassezia (6.6%), and Rhodotorula (2.9%). Cutaneous colonization with yeasts was two-fold higher in the adults than in children (P<0.0001). The distribution of the yeast species was dependent on the body part sampled: Malassezia predominated in the face, neck, and trunk regions (P=0.0047); Candida more frequently colonized hands and legs (P=0.0029).Our study showed that cutaneous yeast flora and distribution of yeast species depends significantly on the age of the AD patient and the body part affected by atopic dermatitis.

This chapter discusses body part nouns, a part of language that is central to human life, and the polysemy that arises in connection with them. Examples from everyday speech and narrative in various contexts are examined in a Papuan language called Koromu and semantic characteristics of body part nouns in other studies are also considered. Semantic templates are developed for nouns that represent highly visible body parts: for example, wapi ‘hands/arms’, ehi ‘feet/legs’, and their related parts. Culture-specific explications are expressed in a natural metalanguage that can be translated into Koromu to avoid the cultural bias inherent in using other languages and to reveal both distinctive semantic components and similarities to cross-linguistic examples.

When a hand (either real or fake) is stimulated in synchrony with our own hand concealed from view, the felt position of our own hand can be biased toward the location of the seen hand. This intriguing phenomenon relies on the brain's ability to detect statistical correlations in the multisensory inputs (ie visual, tactile, and proprioceptive), but it is also modulated by the pre-existing representation of one's own body. Nonetheless, researchers appear to have accepted the assumption that the size of the seen hand does not matter for this illusion to occur. Here we used a real-time video image of the participant's own hand to elicit the illusion, but we varied the hand size in the video image so that the seen hand was either reduced, veridical, or enlarged in comparison to the participant's own hand. The results showed that visible-hand size modulated the illusion, which was present for veridical and enlarged images of the hand, but absent when the visible hand was reduced. These findings indicate that very specific aspects of our own body image (ie hand size) can constrain the multisensory modulation of the body schema highlighted by the fake-hand illusion paradigm. In addition, they suggest an asymmetric tendency to acknowledge enlarged (but not reduced) images of body parts within our body representation.

The objective of this case study was to experimentally manipulate the impact on arousal and recall of two characteristics frequently occurring in gruesome depictions of body parts in smoking cessation advertisements: the presence or absence of an external physical insult to the body part depicted; whether or not the image contains a clear figure/ground demarcation. Three hundred participants (46% male, 54% female; mean age 27.3 years, SD = 11.4) participated in a two-stage online study wherein they viewed and responded to a series of gruesome 4-s video images. Seventy-two video clips were created to provide a sample of images across the two conditions: physical insult versus no insult and clear figure/ground demarcation versus merged or no clear figure/ground demarcation. In stage one, participants viewed a randomly ordered series of 36 video clips and rated how “confronting” they considered each to be. Seven days later (stage two), to test recall of each video image, participants viewed all 72 clips and were asked to identify those they had seen previously. Images containing a physical insult were consistently rated more confronting and were remembered more accurately than images with no physical insult. Images with a clear figure/ground demarcation were rated as no more confronting but were consistently recalled with greater accuracy than those with unclear figure/ground demarcation. Makers of gruesome health warning television advertisements should incorporate some form of physical insult and use a clear figure/ground demarcation to maximize image recall and subsequent potential advertising effectiveness.

AbstractSeveral functional magnetic resonance imaging (fMRI) studies have demonstrated that resting-state brain activity consists of multiple components, each corresponding to the spatial pattern of brain activity induced by performing a task. Especially in a movement task, such components have been shown to correspond to the brain activity pattern of the relevant anatomical region, meaning that the voxels of pattern that are cooperatively activated while using a body part (e.g., foot, hand, and tongue) also behave cooperatively in the resting state. However, it is unclear whether the components involved in resting-state brain activity correspond to those induced by the movement of discrete body parts. To address this issue, in the present study, we focused on wrist and finger movements in the hand, and a cross-decoding technique trained to discriminate between the multi-voxel patterns induced by wrist and finger movement was applied to the resting-state fMRI. We found that the multi-voxel pattern in resting-state brain activity corresponds to either wrist or finger movements in the motor-related areas of each hemisphere of the cerebrum and cerebellum. These results suggest that resting-state brain activity in the motor-related areas consists of the components corresponding to the elementary movements of individual body parts. Therefore, the resting-state brain activity possibly has a finer structure than considered previously.
