Iconicity in Chinese Sign Language and Filipino Sign Language

Sign language is primarily used as a means of communication by the deaf and hard of hearing. Iconicity is considered as its typical feature. This paper makes a preliminary comparison on lexical items between Chinese Sign Language (CSL) and Filipino Sign Language (FSL) through examining the iconic devices used by the CSL and FSL signs. The study provides some valuable evidence that the iconicity is prevalent in CSL and FSL which always use similar iconic device for the same concept due to shared embodied experience though different iconic devices are occasionally used. These iconic devices include direct (1) presentation; (2) number representation; (3) shape representation; (4) movement representation (5) size representation; (6) part-for-whole representation; (7) metonymic/metaphorical representation. The findings of the research could help to reveal the relationship between language and cognition and make some contributions to the communications among the deaf and hard of hearing in both Chian and the Philippines.

Assessing Passive Leg Raise Test in Pediatric Shock Using Electrical Cardiometry

AbstractPassive leg raise (PLR) is widely used to incite an autobolus to assess fluid responsiveness in adults; however, there is a paucity of studies exploring its utility in children. Our study aimed to analyze the efficacy of PLR in determining fluid responsiveness in children presenting with shock using electrical cardiometry. Patients in the age group of 0 to 20 years who presented in shock to our children's hospital emergency department were evaluated. Multiple hemodynamic metrics including, heart rate, systolic/diastolic blood pressure, cardiac output (CO), stroke index, stroke volume (SV), flow time corrected (FTC), and left ventricular ejection time (LVET) were recorded using the noninvasive ICON device and compared at baseline and post-PLR. A total of 68 patients had pre- and post-PLR data available for review between June and July 2022. Median age was 7 years (54% male); most common etiology was hypovolemic (67.6%) shock. Following PLR, there was no significant change in most hemodynamic parameters, including SV and CO; however, there was a significant difference in FTC (301 [pre-PLR] vs. 307 [post-PLR], p = 0.016) (ms) and LVET (232 [pre-PLR] vs. 234 [post-PLR], p = 0.014) (ms). A significantly higher proportion of children diagnosed with septic shock demonstrated fluid responsiveness (ΔSV ≥ 10% from baseline) compared with those with hypovolemic shock (p = 0.036). This study demonstrated no identifiable fluid responsiveness (ΔSV ≥ 10% from baseline) following PLR; however, a significantly higher proportion of children suffering from septic shock demonstrated fluid responsiveness compared with those with hypovolemic shock. Larger studies are needed to further assess the utility of PLR, as well as other modalities, in determining fluid responsiveness in children.

Tara bandu: On the hybridization of a sign

Tara bandu is a traditional ceremony in Timor-Leste that enshrines a customary law with official recognition since independence, which generally applies to the spatial scale of the smallest administrative division of the territory (suco) and several years of timespan, rooting in tradition (lisan), concerning natural resources management and also relations among people. There is evidence related to the concepts of adat (tradition in Indonesia) and pemali (taboo) in Southeast Asia and Austranesia, suggesting that precursors of tara bandu should exist before the Portuguese arrival in the early XVI century. Yet, there was a subsequent diachronic process of hybridization of static iconic devices and other traditional Timorese practices with the vocalized Portuguese colonial bandos, evolving to a choreographic complex ritual with several semiotic dimensions: the sacrificial animist performance addressed to the ancestor’s spirits and a supernatural environment (lulik), dances and others including Catholic rites, then focusing on written documents endorsing commitments. Contemporaneously, tara bandu is a salient event anchoring communities in defining participatory land use plans including agreements on property boundaries, rules of engagement and also interdictions and sanctions. Tara bandu is mentioned nowadays as an example and case-study of bottom-up strategies for environmental peacebuilding processes.

The efficacy of enhanced recovery protocol from anesthesia in diabetic patients undergoing radical cystectomy

ABSTRACT Background: Prevalence of diabetes in surgical patients is 10–40%. They have higher incidence of complications, and longer stay in hospital compared to non-diabetic. Radical cystectomy with urinary diversion is considered one of the high-risk surgeries associated with morbidity and mortality. Enhanced recovery after surgery (ERAS) is an evidence-based multimodal surgical care protocol that improves post-operative outcomes and length of stay (LOS) in patients without diabetes. This study evaluates the evidence on whether diabetic patientswould benefit from ERAS pathway. The aim of the study: was to evaluate the efficacy of ERAS protocol from anesthesia in diabetic patients undergoing radical cystectomy. Patients and methods: This study was carried out in Alexandria main University Hospital on fifty-four adult ASA physical status I, II and III participants of either sex. Participants were scheduled for radical cystectomy surgeries under the effect of general anesthesia, following ERAS protocol, divided into two group diabetic and non-diabetic27 participants each. The ICON device was used to measure the stroke volume variation (SVV) to apply goal-directed fluid therapy (GDFT) for all patients. Measurements: Demographic data, hemodynamic parameters (stoke volume, cardiac index), intra-operative fluid requirement, blood loss, postoperative pain intensity, time of first bowel movement, PH, Bicarbonate level, serum lactate level, heamatocrit and LOS were measured and recorded. Main results: No statistical significant difference was detected between both groups as regard age, sex, weight, vital signs, serum lactate, first bowel movement and VAS. There was statistical significant difference between both groups as regard fluid requirement, and the days of hospital stay. Conclusion: ERAS is a beneficial protocol to improve postoperative outcome in radical cystectomy surgeries, it can be used in diabetic patients to decrease postoperative morbidity and mortality.

Thoracic fluid content: a novel parameter for detection of pulmonary edema in parturients with preeclampsia.

Acute pulmonary oedema is a serious complication of preeclampsia. Early detection of pulmonary edema in preeclampsia would improve fluid management and would also allow earlier detection of severe cases. The aim of this work is to evaluate the ability of thoracic fluid content measured by electrical cardiometry for early detection of pulmonary edema in parturients with preeclampsia. A prospective observational study included a cohort of preeclamptic parturients. On admission, lung ultrasound score was calculated, and thoracic fluid content was recorded using electrical cardiometry ICON device. Area under receiver operating characteristic (AUROC) curve was calculated for lung ultrasound score, thoracic fluid content for detection of pulmonary edema. Spearman correlation coefficient was calculated for correlation between lung ultrasound score and thoracic fluid content. Sixty patients were included in the study; of them, 6 patients (10%) required diuretics for pulmonary edema. Patients with pulmonary edema had higher lung ultrasound score and thoracic fluid content compared to other patients. Good correlation was reported between Lung ultrasound score and thoracic fluid content (r = 0.82). Thoracic fluid content and lung ultrasound score showed excellent diagnostic properties for pulmonary edema {AUROC: 0.941 (0.849-0.986), best cut-off value: 40kohm-1}, and {AUROC: 0.961 (0.887-0.994), best cut-off value of 15.7}. In parturients with preeclampsia, both lung ultrasound score and thoracic fluid content showed excellent properties for detection pulmonary edema. The high negative predictive value of both tests makes them useful screening tests to rule out pulmonary edema. The excellent correlation between both measures suggests that electrical cardiometry could be a promising surrogate to ultrasound for assessment of extravascular lung water.

Impact of Obesity on Noninvasive Cardiac Hemodynamic Measurement by Electrical Cardiometry in Adults With Aortic Stenosis

There are substantial potential benefits to noninvasive cardiac monitoring methods, such as electrical cardiometry (EC), over more invasive methods, including significantly reduced risk of complications, lower up-front and operational costs, ease of use, and continuous monitoring. To take advantage of these technologies, clinical equivalence to currently established methods must be determined. The authors sought to determine if the noninvasive measurement of cardiac index (CI) by EC was clinically equivalent to thermodilution (TD) in adult patients with aortic stenosis (AS). This is a cross-sectional study comparing measurement devices in a single patient group. Single-center, university teaching hospital. The study included 52 adult patients with aortic stenosis undergoing right heart catheterization. Cardiac output (CO) was measured concurrently using EC with an ICON device and TD in 52 participants with AS. CI values were to determine the accuracy and precision of EC in reference to TD. Percentage error (PE) was used to assess their clinical equivalence. The participants were divided further into groups (normal and overweight/obese) based on body mass index and the analysis was repeated. CO measurement made by EC in adult patients with obesity or overweight was reduced significantly relative to TD. This was not observed in normal-weight adult AS patients. EC provided clinically equivalent measurements to TD for measuring CI in normal-weight adult AS patients (PE = 25.0%), but not for those adult AS patients with overweight or obesity (PE = 42.3%). Overall, the ICON device produced lower CO and index measurements relative to TD in adult patients with AS. Overweight and obesity also significantly affected the relative precision and accuracy of the ICON electrical cardiometric device to measure CI in these patients.

Size and shape depictions in the manual modality: A taxonomy of iconic devices in Adamorobe Sign Language

AbstractThis paper presents a model of size and shape depiction in the manual modality, based on a micro-level analysis of the lexicon of Adamorobe Sign Language (Ghana). The model combines strong elements of previous models, such as a dyadic labeling system separating form and meaning as suggested in

Swipe To Unlock

Abstract Since the release of iconic devices like the Nintendo DS (2004) and particularly the first iPhone (2007), touchscreen interfaces have become almost omnipresent and arguably shaped a “touchscreen generation”. But how do touchscreen experiences operate as complex assemblages of material contingencies, electronics, algorithms and user interaction? And how do they function in actual software applications? In order to address these questions, the paper outlines a comparative software studies perspective, which comprises four consecutive steps. The introduction draws on cultural studies research on touchscreen interfaces to establish a theoretical framework for understanding the shifting epistemic status of the screen and the complex relationship between technical affordances and cognitive processes. Second, the paper explores aesthetic implications of the materiality of touchscreens, including the shift from vertical to horizontal navigational logic and the focus on physical contiguity in user experience design. Third, a series of short, interconnected case studies serves to illustrate the more specific implications on practices of media use and cultural production in a variety of applications. For example, apps like Vine evoke the ‘tangibility’ of digital material by allowing users to start and stop recording video by touching and releasing the screen respectively. Other, even more iconic examples include the swipe mechanic employed in Tinder and particularly the ‘swipe to unlock’ gesture used in the Android operating system. Finally, the previous findings are contextualised by briefly investigating the cultural imaginary of the touchscreen, which manifests itself in the form of haptic feedback as well as curved and even wearable touch-sensitive surfaces.

A leitura do texto literário: uma abordagem semiótica

Communicative practices involve, in general, the simultaneous action of symbols, indices and icons. The semiosis of a literary text is not different, so it is virtually impossible to isolate a text which is purely symbolic, indexical or iconic. However, it is possible to identify contexts in which one of these modes of representation appears more strongly, and so becomes crucial to reveal the effects which the author wants to emphasize. The aim of this paper is to describe some situations in which the emphasis in each of these three modes determines our perception of specific meanings in poems and narratives. To this end, we use Peirce’s Theory of Signs, specifically his second thrichotomy, which deals with the relations between signs and their objects. These concepts are taken here in their theoretical sense, then they are applied to the specific context of literary texts, while we read some works by renowned authors in Brazilian literature as Manuel Bandeira, Joao Guimaraes Rosa, Carlos Drummond de Andrade and Joao Cabral de Melo Neto. More than summarizing a classification framework, we aim to demonstrate that understanding the symbolic, indexical and iconic devices in these texts requires different cognitive strategies of the literary phenomenon.

Language Between Bodies: A Cognitive Approach to Understanding Linguistic Politeness in American Sign Language

This article proposes an answer to the primary question of how the American Sign Language (ASL) community in the United States conceptualizes (im)politeness and its related notions. It begins with a review of evolving theoretical issues in research on (im)politeness and related methodological problems with studying (im)politeness in natural signed-language interaction. Because human conceptual systems of abstract notions such as (im)politeness employ cognitive metaphorical mappings and because ASL has strong iconic devices at its disposal, this article reports the results of applying the conceptual metaphor theory (Lakoff and Johnson 1980; Lakoff 1987, 1993; Wilcox 2000; Taub 2001; see also Steen 2007 and Steen et al. 2010) to an analysis of ethnographically collected linguistic data. Because conceptualizations of (im)politeness are better understood as part of a broader system of conceptual domains, this article provides a survey of metaphorical (as well as metonymical and image schematic) mappings and their respective linguistic expressions, which constitute ASL's (im)politeness-related system of domains. Also included is a discussion of how this methodological and analytical approach may advance theoretical notions of (im)politeness.

Iconicity in different types of gestures

The paper presents a framework for classifying gestures in terms of different parameters, and shows that the parameter of iconicity cuts across that of cognitive construction, which distinguishes codified gestures — those represented in memory as stable signal–meaning pairs — from creative ones — those invented on the spot on the basis of a few generative rules. While creative gestures are necessarily iconic, because they can be understood only thanks to their iconicity, codified gestures can be iconic too. A model for the generation of iconic gestures is presented, according to which, to create a new gesture, people select the features of the meaning to imitate in terms of their distinctiveness, ease of representation and ontological type. Finally, some principles for measuring the iconicity of gestures of Hearers and Signs of the Deaf are illustrated, thus outlining the continuity of iconic devices between creative and codified gestures.
