Harnessing Women’s Potential as a Soft Engine for Growth : Lessons from Contrasting Trajectories between Finland and Japan for Growing Economies
2017
Harnessing the vigor of women’s potential is essential for inclusive economic growth in a digital economy moving toward aging society. This can be a soft engine for sustainable growth substitutable for costly hard investment. While there exists explicit evidence of a virtual cycle between economic growth and gender balance improvement, emerging countries cannot afford to overcome the constraints of low income. Given the foregoing, this paper analyzed possible co-evolution between economic growth, gender balance improvement and digital innovation initiated by information and communication technology (ICT) advancement. Using a unique dataset representing the state of gender balance improvemen…
On the friction/tangential restitution problem: Independent friction-restitution modeling of sphere rebound with arbitrary spin
2023
Most descriptions of collision events introduce coefficients of friction and tangential restitution which vary significantly with the impact angle, in contrast with the independence of the normal coefficient of restitution with this parameter. A redefinition of the coefficients of friction and tangential restitution based on the idea that friction and restitution effects can be treated as being mutually independent, provides a satisfactory description of experimental data using a ‘constant’ restitution coefficient independent on the impact angle. This independent friction-restitution modeling is developed here for the rebound of a homogeneous sphere having an arbitrary spin on a rough massi…
Design of mobile phones for older adults : An empirical analysis of design guidelines and checklists for feature phones and smartphones
2017
Design guidelines and checklists are suggested as a useful tool in the development and evaluation of interface design of mobile phones for older adults. Given the intense evolution of mobile phone design, understanding how the design guidelines and checklists have taken into account the advances in mobile phone usability for older adults is important for their correct application and future development. Thus, this study explores the usability dimensions of mobile phone design for older adults and the related changes in terms of time and the type of device (feature phones vs. smartphones) based on an expert coding of the eight mobile phone design guidelines and checklists for older adults pu…
Task-Specific Organic Salts and Ionic Liquids Binary Mixtures: A Combination to Obtain 5-Hydroxymethylfurfural From Carbohydrates
2019
The increase in energy demand and depletion of fossil fuels are among major issues of modern society. Valorization and transformation of raw materials in products of industrial value represents a challenge. This justifies the growing interest of scientific research towards the identification of suitable media and methodologies able to pursue above goals, paying attention to matter of sustainability. On this subject, we studied sulfonic-acid functionalized diimidazolium salts as catalysts for the conversion of fructose and sucrose to 5-hydroxymethylfurfural (5-HMF) in an ionic liquid mixture. In general, using these salts allowed us to obtain 5-HMF in good yields from both substrates in mild…
Interaction of the n-terminal domain of human t1r2 taste receptor with brazzein, a sweet-tasting protein
2015
Brazzein is a small (6.5 kDa) sweet-tasting protein originating from the fruit of Pentadiplandra brazzeana, a plant found in West Africa. Brazzein like all classes of sweet compounds is perceived through the activation of the T1R2/T1R3 heterodimeric sweet-taste receptor. T1R2 and T1R3 subunits are members of the small family of class C G-protein coupled receptors (GPCRs). Class C GPCRs possess a large N-terminal domain (NTD) linked to seven transmembrane domain by a cysteine rich domain (CRD). The NTD of T1R2 (T1R2-NTD) has been shown to contain the primary binding site for most of the sweet ligands. However, brazzein has been shown to require CRD of human T1R3 for receptor activation [1]. …
Piecing together the taste signaling puzzle
2010
International audience; The identification of the genes coding for bitter, umami, sweet and sour taste receptors has provided us with unique tools to investigate the gustatory system. As a consequence, tremendous progress towards our understanding of the functional organization of the peripheral taste system has been achieved over the past decade. In particular, key components of the taste receptors signaling cascades have been identified as well as populations of chemosensory cells in the olfactory, respiratory and digestive systems expressing taste receptors. Besides sharing receptors and signaling molecules (gustducin, phospholipase-C b2…) with taste bud cells, these cells display a simi…

Are quality management practices enough to improve process innovation?
2015
The popularity of quality management as a system for continuous improvement has not been accompanied by deep theoretical understanding of its effects on process innovation. In this work, the resource-based view serves as the basis for the construction of a model designed to explain the effects of quality management practices (QMP) on process innovation performance and the mediating role of dynamic capabilities in this relationship. The empirical data were analysed using the structural equation modelling technique by examining 6 competing models that represent full, partial mediation and non-mediation relationships on a sample of 550 Spanish industrial companies. The findings indicate that t…
Emotions in Technology Design
2020
Understanding emotions is becoming ever more valuable in design, both in terms of what people prefer as well as in relation to how they behave in relation to it. Approaches to conceptualising emotions in technology design, how emotions can be operationalised and how they can be measured are paramount to ascertaining the core principles of design.Emotions in Technology Design: From Experience to Ethics provides a multi-dimensional approach to studying, designing and comprehending emotions in design. It presents emotions as understood through basic human-technology research, applied design practice, culture and aesthetics, ethical approaches to emotional design, and ethics as a cultural frame…
