Classroom Spoken Discourse and Casual Conversation: A Comparison using Hymes's Ethno-methodological Framework Doms, David. 2003. Classroom Spoken Discourse and Casual Conversation: A Comparison using Hymes's Ethno-methodological Framework, English Language and linguistics 15, 167-190. this paper attempts to examine discourse carried out in classrooms and various naturalistic settings by using Hymes's ethno-methodological approach (1972) for exploring speech events. As compared to previous studies which have been done cross-sectionally and paid attention to describing and accounting for L2 leamers' grammatical competence mainly in a quantitative fashion, the present study attempts to tap leamers' discourse competence by qualitatively looking at ongoing conversations in various places. After summarizing the distinguishing features of an English language classroom activity and casual conversations through short real-life examples taken from my own data, I discuss the implications of the analysis for the development of learners' conversational skills and discoursal knowledge in E.F.L. classrooms. Key words: ethno-methodology, Hymes, spoken discourse, classroom talk, casual conversation

Consistency relation and inflaton field redefinition in the <i>δN</i> formalism
Domè,nech, Guillem,Gong, Jinn-Ouk,Sasaki, Misao North-Holland Pub. Co 2017 Physics letters. Section B Vol.769 No.-
<P><B>Abstract</B></P> <P>We compute for general single-field inflation the intrinsic non-Gaussianity due to the self-interactions of the inflaton field in the squeezed limit. We recover the consistency relation in the context of the <I>δN</I> formalism, and argue that there is a particular field redefinition that makes the intrinsic non-Gaussianity vanishing, thus improving the estimate of the local non-Gaussianity using the <I>δN</I> formalism.</P>

Work Ability Index: Psychometric Testing in Aeronautical Industry Workers
González-Domínguez María Eugenia,Fernández-García Elena,Paloma-Castro Olga,González-López Regina María,Rivas Pérez María Paz,López-Molina Luis,García-Jiménez Jesús,Romero-Sánchez José Manuel 한국산업안전보건공단 산업안전보건연구원 2024 Safety and health at work Vol.15 No.1
Background The Work Ability Index (WAI) is an instrument that measures work ability. The wide dispersion of the WAI internationally has led to its adaptation for use in different countries. This study aimed to evaluate the psychometric properties of the Spanish version of the WAI. Methods A methodological design was used over an opportunistic sample of 233 workers in the aeronautical industry in Spain. Reliability was evaluated through internal consistency. Factorial validity, known groups, and convergent validity were tested. Results The Cronbach's alpha and item-total correlation indicated an adequate internal consistency. The confirmatory factor analysis, performed to evaluate the factorial validity, found adequate fit indices for a two-factor solution with a high correlation between the factors. Factor 1, “Subjectively estimated work ability and resources”, was composed of 3 subscales and factor 2, “Ill-health-related”, of 2 subscales. Subscales 4 and 6 had loading in both factors. Workers under 45 years of age obtained higher significant scores than older ones. Convergent validity was also evidenced since WAI was highly correlated with self-assessment of health status. Conclusions The Spanish version of the WAI has shown evidence of reliability and validity in this study, supporting its use in individual and collective health surveillance by occupational health professionals. The factorial solution that was found has previously been reported in another international context. However, further research is needed to resolve the discrepancies detected in the role of some subscales between other national and international studies.

The recognitions of phases and precise grain boundaries based on metallographic images are useful for conducting micromechanicalsimulations, such as finite element analysis and peridynamics. In this work, those processes are automatized byusing a Sobel operator for identifying edges, which is normalized by different proposed Gaussian filters (on intensity, rugosity,or both). After that, a threshold is used to discretize the edges. Different neighboring pixel configurations, sensitive to edgeintensity, are proposed for thinning and cleaning the discretized edges, and hence, grain boundaries with a one-pixel thicknessare obtained. Then, the phase is selected by averaging color of each delimited grain. Finally, the precision on the phaserecognition was found to increase from 75.61 to 83.6% for the unmodified and the normalized Sobel operator, respectively.

Fourier transform mid-infrared (Mid-FTIR) spectroscopyin conjunction with multivariate analysis was used to predict thecapsaicin content, ascorbic acid, total phenolic compounds, andantioxidant activity of Capsicum annuum L. variety serrano. Twomultivariate calibrations, partial least square (PLS), and principalcomponent regression (PCR) were optimized to construct thecalibration models. The best models used to quantify the abovementioned compounds were obtained with the PLS algorithm andcoefficients of determination (R2) greater than 0.998 as well as astandard error calibration less than 0.098. The results demonstratedthat Mid-FTIR spectroscopy in combination with multivariateanalysis can be effectively used for to quantify the capsaicin,ascorbic acid, total phenol content, and antioxidant activity ofCapsicum annuum var. serrano. Mid-FTIR spectroscopy incombination with multivariate calibration offers rapid, easy samplepreparation, is environmentally friendly, and is operationallyuncomplicated, demonstrating the significant advantages of thechemometric models compared with conventional methods ofanalysis.

Heterophilic antibodies are human immunoglobulins directed against various animal antigens. They can produce false-positive results in the analysis of different tumor markers, including prostate-specific antigen. This interference can lead to misdiagnosis, unnecessary tests, and overtreatment in some cases. We present herein the case of a 52-year-old man with repeated spurious elevation of prostate-specific antigen, reaching levels of 108.7 ng/mL, that were suspected to be caused by heterophilic antibodies. The interference was solved by changing the analysis technique. Real values of prostate-specific antigen were less than 1 ng/mL.

Not just sensitization: sympathetic mechanisms contribute to expand experimental referred pain
Víctor Doménech-García,Alberto Rubio Peirotén,Miren Lecea Imaz,Thorvaldur Skuli Palsson,Pablo Herrero,Pablo Bellosta-López 대한통증학회 2022 The Korean Journal of Pain Vol.35 No.3
Background: Widespread pain partially depends upon sensitization of central pain mechanisms. However, mechanisms controlling pain distribution are not completely known. The present study sought to assess skin temperature variations in the area of experimentally-induced pain and potential sex differences. Methods: Pressure-pain thresholds (PPTs) were measured on the right infraspinatus muscle. At the end of Day 0, all participants performed an eccentric exercise of the shoulder external rotators to induce muscle soreness 24 hours after. On Day 1, participants indicated on a body chart the area of pain induced by 60 seconds of suprathreshold pressure stimulation (STPS; PPT + 20%) on the right infraspinatus muscle. Skin temperature variations in the area of referred pain were recorded with an infrared thermography camera, immediately before and after the STPS. Results: Twenty healthy, pain-free individuals (10 females) participated. On Day 0, the pre-STPS temperature was higher than the post-STPS temperature on the arm (P = 0.001) and forearm (P = 0.003). On Day 1, the pre-STPS temperature was higher than the post-STPS temperature on the shoulder (P = 0.015), arm (P = 0.001), and forearm (P = 0.010). On Day 0, the temperature decrease after STPS in females was greater than in males on the forearm (P = 0.039). On Day 1, a greater temperature decrease was found amongst females compared with males at the shoulder (P = 0.018), arm (P = 0.046), and forearm (P = 0.005). Conclusions: These findings indicate that sympathetic vasomotor responses contribute to expand pressure-induced referred pain, especially among females.

Enhanced solid element for modelling of reinforced concrete structures with bond-slip
Norberto Domínguez,Marco Aurelio Fernández,Adnan Ibrahimbegovic 사단법인 한국계산역학회 2010 Computers and Concrete, An International Journal Vol.7 No.4
Since its invention in the 19th century, Reinforced Concrete (RC) has been widely used in the construction of a lot of different structures, as buildings, bridges, nuclear central plants, or even ships. The details of the mechanical response for this kind of structures depends directly upon the material behavior of each component: concrete and steel, as well as their interaction through the bond-slip, which makes a rigorous engineering analysis of RC structures quite complicated. Consequently, the practical calculation of RC structures is done by adopting a lot of simplifications and hypotheses validated in the elastic range. Nevertheless, as soon as any RC structural element is working in the inelastic range, it is possible to obtain the numerical prediction of its realistic behavior only through the use of non linear analysis. The aim of this work is to develop a new kind of Finite Element: the “Enhanced Solid Element (ESE)” which takes into account the complex composition of reinforced concrete, being able to handle each dissipative material behavior and their different deformations, and on the other hand, conserving a simplified shape for engineering applications. Based on the recent XFEM developments, we introduce the concept of nodal enrichment to represent kinematics of steel rebars as well as bonding. This enrichment allows to reproduce the strain incompatibility between concrete and steel that occurs because of the bond degradation and slip. This formulation was tested with a couple of simple examples and compared to the results obtained from other standard formulations.

Raúl Domínguez,Antonio Jesús-Sánchez-Oliver,Eduardo Cuenca,Pablo Jodra,Sandro Fernandes da Silva,Fernando Mata-Ordóñez 한국운동영양학회 2017 Physical Activity and Nutrition (Phys Act Nutr) Vol.21 No.4
[Purpose] Swimming requires developing a high aerobic and anaerobic capacity for strength and technical efficiency. The purpose of this study was to establish the nutritional requirements and dietary strategies that can optimize swimming performance. [Methods] Several related studies retrieved from the databases, Dialnet, Elsevier, Medline, Pubmed, and Web of Science, through keyword search strategies were reviewed. [Results] The recommended carbohydrate intake ranges between 6-10-12 g/kg/d, protein 2 g/kg/d, and fat should surpass 20-25% of the daily intake. [Conclusion] Performance can be optimized with a hydration plan, as well as adequate periodization of supplements, such as caffeine, creatine, sodium bicarbonate, B-alanine, beetroot juice, Vitamin D, bovine colostrum, and HMB.
