Dual Enzyme-Triggered Controlled Release on Capped Nanometric Silica Mesoporous Supports
2012
The development of nanoscopic hybrid materials equipped with “molecular gates” showing the ability of releasing target entrapped guests upon the application of an external trigger has attracted great attention and has been extensively explored during recent years.1 These nanodevices are composed of two subunits, namely, a suitable support and certain capping entities grafted on the surface of the scaffolding.2 The support is used as a suitable reservoir in which certain chemicals can be stored whereas the molecules grafted in the outer surface act as a “gate” and can control the release of the entrapped molecules at will. Both components are carefully selected and arranged in order to achie…
Aceptación del pago móvil en España: análisis de la conveniencia y la usabilidad en el contexto de una batalla generacional
2017
Entender la aceptación y el uso de una nueva tecnología constituye una de las corrientes más maduras y fructíferas de investigación dentro de los sistemas de información. Contar con un modelo que maximice el poder explicativo sin perder de vista el contexto de utilización y las características de los usuarios, se ha transformado en un imperativo. El propósito central de la investigación propuesta consiste en presentar y contrastar un modelo holístico de síntesis de aceptación voluntaria de una tecnología, por parte de un consumidor individual. Este modelo integrará distintas perspectivas, aplicadas a la adopción del servicio de pago móvil. Asimismo, se analizará el impacto de la brecha gene…
User-Centered Development of Video Telephony for Servicing Mainly Older Users: Review and Evaluation of an Approach Applied for 10 Years
2006
A research and development (R&D) approach has been applied to video telephony (VT) in northern Finland since 1994 by broad consortia. The focus has been on the considerable involvement of ergonomics within the engineering and implementation of VT. This multidisciplinary participatory ergonomic R&D approach (PERDA) is described briefly, in general and through two cases. The user-centeredness should be discernible in this sociotechnical systemic entity. A consortium—comprising mainly manufacturers, individual and organizational users of technological products, and R&D organizations—serves as a natural context for product development. VT has been considered to have much potential for enhancing…
Lithic Management in the Chassey Culture Neolithic
2009
The integrated technological approach of the lithic industries in Southern France Chassey culture and neighbouring cultures is a way to highlight a complex organisation of space. The development of long distance diffusion networks of lithic products from western Provence creates interdependence between producing-exporting sites and receiving-consuming sites. The analysis of their functioning, from raw material sources until remote consuming sites, is undergone on various scales (from supra-regional to local), through lithic technology and use wear analysis.
L’habitat durable sans l’habiter ? Fabrique de la densité en Bourgogne
2017
In 2009 and 2010, in order to combat the urban sprawl, the Grenelle Environment sets out urban density as a public policy issue. This notion builds on a modus operandi of an urbanization regime that includes both the environmental and the participatory dimensions in its approach. This injunction of sustainability is there implemented through a range of standards, rules and procedures, while the stakeholders in urbanism strive to arrange the experience of inhabiting. But how does this apparatus take the test of reality into account? Based on a qualitative research carried out from 2012 to 2015 on urban planning projects intended to increase density in urban and suburban areas in Burgundy, th…
Female reproductive factors are associated with objectively measured physical activity in middle-aged women
2017
Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women. In addition, we examined the association of physical activity with female reproductive factors at midlife. The study population consisted of 647 women …
From Analysis to Formulation of Strategies for Farm Advisory Services (Case Study: Valencia – Spain). an Application through Swot and Qspm Matrix
2019
Abstract European agriculture should meet new increasing internal and contextual challenges. For example, the reform of the Common Agricultural Policy in 2003 introduced the cross-compliance, among other novelties, as compulsory for farmers. To better meet this and other requirements, Member States had to set up the so-called Farm Advisory System, operational across the European Union in 2007. From a sample of actors involved in the provision of farm advisory services in the region of Valencia (Spain), the present study aimed to identify the most appropriate strategies to implement such services. SWOT method has been applied to examine the internal and external environment. Based on this di…
Utility of Alternative Effect Size Statistics and the Development of a Web-Based Calculator: Shiny-AESC
2018
Alternative displays of effect size statistics can enhance the understandability and impact of validity evidence in a variety of applied settings. Arguably, the proliferation of alternative effect size statistics has been limited due to the lack of user-friendly tools to create them. Common statistical packages do not readily produce these alternative effect sizes and existing tools are outdated and inaccessible. In this paper, I introduce a free-to-use web-based calculator (https://dczhang.shinyapps.io/expectancyApp/) for generating alternative effect size displays from empirical data. This calculator requires no mathematical or programming expertise, and therefore, is ideal for academics …
Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing
2021
AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…
Creating Implicit Measure Stimulus Sets Using a Multi-Step Piloting Method
2023
The effect of arbitrary stimulus selection is a persistent concern when employing implicit measures. The current study tests a data-driven multi-step procedure to create stimulus items using a combination of free-recall and survey data. Six sets of stimulus items were created, representing healthy food and high sugar items in children, adolescents, and adults. Selected items were highly representative of the target concepts, in frequent use, and of near equal length. Tests of the piloted items in two samples showed slightly higher implicit measure–behavior relations compared to a previously used measure, providing preliminary support for the value in empirically based stimulus selection.
