Case and Contact Linguistics
2012
Abstract Language contact affects case categories in various ways. This article examines the effects of contacts between linguistic codes (languages, unrelated or related, or language varieties): changes in one code on the model of another. It deals with inflectional case markers, affixes, and adpositions from which they evolve. Though most adpositions express more specific relations, some are relatively desemanticised. Affixes and case-like adpositions may fulfil similar functions; the close correspondences between Dravidian case suffixes and Indic postpositions. Case markers and case functions are acquired through what is called ‘borrowing’, ‘diffusion’, ‘transfer’, ‘interference’, ‘repli…
A preliminary investigation of the effect of contact pressure on the accuracy of heart rate monitoring by wearable PPG wrist band
2019
The increase of safety and health monitor of workers has become a crucial objective to prevent excessive physical workloads, injuries, accidents and errors. Heart rate (HR) is a very important physiological indicator which could properly describe the workers’ physical status. Recently, wearable photoplethysmographic (PPG) wristband trackers have been utilized to measure HR without hindering normal gesture of workers. However, the quality of PPG signals is highly affected by human physical motions, resulting in a poor reliable HR estimation. Specifically, during different activities and gestures, PPG sensor contact pressures may have an impact on the quality of the heart rate signal. To appr…
Etude d'un emmanchement fretté compte tenu de l'effet combiné des défauts de forme et d'état de surface
2012
The main purpose of this thesis is to present two contributions in the field of shrink fitassembly taking into account the defects of form and roughness surfaces. The first contributionconcerns the study of the influence of the defect forme on the characteristics of shrinked assemblyusing an approach based on finite element modeling. We found that this defect has a significantinfluence on the resistance of the assembly. The work already done in the laboratory of mechanicsat the University of Bourgogne have been confirmed. In the second contribution, we proposed tointegrate the surface defects (roughness) by creating a homogenized finite element interface. Thistechnique has facilitated the m…
Propuestas creativas, educativas y terapéuticas. Cómo trabajar con alumnado con problemas sociales
2013
This article comes from the idea that Elementary Spanish classrooms are in dire need of improvement in terms of social relations, not only because of the significant cultural changes that occurred during the dawn of the twenty-first century as a result of migration flows, but because of global economic complications and technological advances that have complicated relationships. In this situation, this article offers a compilation of different activities in the area of artistic expression of Elementary Education, with the aim of improving social contact and relationships of the students of this educational stage. At the same time, it has been considered essential to characterize these activ…
La natura della responsabilità medica: il cambio di rotta
2020
ABSTRACT A tre anni di distanza dall’ approvazione della riforma il saggio propone una riflessione sulla natura della responsabilità medica ed, in particolare, sulla tenuta del presunto cambio di rotta rispetto alla teoria del contatto sociale, alla luce di un diritto vivente divenuto ius receptum e delle sollecitazioni alternative che l’autore individua in una differente lettura della nuova normativa. Three years after the approval of the reform, the essay proposes a reflection on the nature of medical liability and, in particular, on the keeping of the presumed change of course with respect to the theory of social contact, in the light of a case law that has become ius receptum and the al…
Metal/Semiconductor Barrier Properties of Non-Recessed Ti/Al/Ti and Ta/Al/Ta Ohmic Contacts on AlGaN/GaN Heterostructures
2019
This paper compares the metal/semiconductor barrier height properties of non-recessed Ti/Al/Ti and Ta/Al/Ta contacts on AlGaN/GaN heterostructures. Both contacts exhibited a rectifying behavior after deposition and after annealing at temperatures up to 550 °
Nonsmooth Mechanics. Convex and Nonconvex Problems
1999
Nonlinear, multivalued and possibly nonmonotone relations arise in several areas of mechanics. A multivalued or complete relation is a relation with complete vertical branches. Boundary laws of this kind connect boundary (or interface) quantities. A contact relation or a locking mechanism between boundary displacements and boundary tractions in elasticity is a representative example. Material constitutive relations with complete branches connect stress and strain tensors, or, in simplified theories, equivalent stress and strain quantities. A locking material or a perfectly plastic one is represented by such a relation. The question of nonmonotonicity is more complicated. One aspect concerns…
Anxiety and coping dispositions as predictors of the visual interaction between mother and child
1991
Abstract The “model of coping modes” distinguishes four dispositionally determined patterns of behavior (coping modes) which become apparent in stressful situations: repression, sensitization, nondefensiveness, and high anxiety. Following from this model, the present study is aimed at assessing associations between coping modes and children's looking behavior towards their mothers in a moderately stress-inducing laboratory setting. The visual exchange of 63 mothers and their eight- to 14-year-old children was observed during a ten-minute planning period for a Punch and Judy show which the child had to later perform. A close visual orientation toward the mother was registered for sensitizers…

Factors influencing tourists’ intention to use COVID-19 contact tracing app
2020
AbstractThe purpose of this study was to develop and test a model that explores the antecedents of tourists’ acceptance of COVID-19 contact tracing app (CTA). Data was obtained from a crowdsourcing platform (Pollfish), in which 400 respondents answered the questionnaire. We used SmartPLS to analyse the data. Results reveal that trust and structural assurance have the strongest relationship. Furthermore, the relationship between trust and destination safety was positive. Finally, self-efficacy moderated the relationship between trust and intention, implying that trust was stronger for tourists who have higher levels of self-efficacy. Recommendations are offered.
