Environmental sustainability in hotels: a matter of category?

2012

As in other economic activities, companies in the hospitality industry have proposed several practices and implemented technology solutions to pursue environmental sustainability of their activities and minimise their impact on climate change. Some applications of information and communication technologies (ICT) may contribute to the reduction of the demand of supplies, water and energy by hotels. In the present paper, we aim at exploring the influence of the hotel category on the implementation of environmental-friendly technologies in hotels. Considering a sample of Spanish hotels in the most important cities, we evaluate the relationship between the level of implementation of certain tec…

HIV-Infected Children and Nutrition: The Friend and The Foe

2019

The impact of nutrition on HIV-infected children has been evaluated in multiple studies. Our review of the current trends of nutrition-related studies revealed that the focus has moved from simply the disease consequences of HIV to ensuring that antiretroviral therapy-treated children are well nourished to ensure growth and development. This update aims to present the state of the art regarding nutrition of HIV-infected children and the real potential for nutrition to serve as a dynamic therapy in this group. Recent World Health Organization reports indicate that the HIV/AIDS disease is curbing in incidence worldwide despite the high 1.8 million children, less than 15 years, reported in 201…

Idées pour uné echoppe simple

2006

L’article propose une réflexion sur certaines questions récurrentes dans les villes européennes. Qui concerne la rénovation et les transformations des types de centres historiques et de leurs tissues, relatives aux nouvelles habitudes et aux nouvelles façons de vivre et d'habiter dans les villes. Les limes thèmes d'études liés à ces questions, concernent surtout des notions comme celles de comptabilité, d'adaptation, de mesure, de cohabitation, d'identité. Afin de trouver une nouvelle identité aux échoppes sans ignorer leur hérédité, la stratégie adoptée pour répondre aux questions du concours, se fonde essentiellement sur deux principes: 1) la reconnaissance et 1'adoption d'un système préc…

The Effects of Database Complexity on SQL Query Formulation (journal-first)

2020

The learning of practical Structured Query Language (SQL) skills often takes place in digital environments, where the learner writes queries against an exercise database. The exercise database is usually designed and implemented by the teacher, and populated with makeshift data. Although this approach is common, and SQL taught in almost all database courses, little scientific attention has been given to the nature of the exercise database.

RDB2OWL

2010

RDB2OWL is a simple approach of mapping relational databases into independently developed OWL ontologies. The approach is based on creating a mapping RDB schema, filling it with mapping information from which SQL scripts are generated that perform the instance-level transformation. We describe the RDB2OWL mapping schema and report on successful application of the technology to the migration of Latvian medical registries data.

The Effects of Database Complexity on SQL Query Formulation

2020

In Structured Query Language (SQL) education, students often execute queries against a simple exercise database. Recently, databases that are more realistic have been utilized to the effect that students find exercises more interesting and useful, as these databases more accurately mimic databases students are likely to encounter in their future work environments. However, using even the most engaging database can be counterproductive to learning, if a student is not able to formulate correct queries due to the complexity of the database schema. Scientific evidence on the effects of database complexity on student’s query formulation is limited, and with queries from 744 students against thr…

MOLECULAR DYNAMICS - MULTIPLE RECEPTOR CONFORMATIONS APPROACH TO ENHANCE STRUCTURE-BASED VIRTUAL SCREENING ON PPAR-alpha RECEPTOR

2016

2016

How do individuals emotionally cope with the imminent real-world salience of mortality? DeWall and Baumeister as well as Kashdan and colleagues previously provided support that an increased use of positive emotion words serves as a way to protect and defend against mortality salience of one’s own contemplated death. Although these studies provide important insights into the psychological dynamics of mortality salience, it remains an open question how individuals cope with the immense threat of mortality prior to their imminent actual death. In the present research, we therefore analyzed positivity in the final words spoken immediately before execution by 407 death row inmates in Texas. By u…

An Efficient Traceable Attribute-Based Authentication Scheme with One-Time Attribute Trees

2015

Attribute-based authentication (ABA) is a way to authenticate signers by means of attributes and it requests proof of possessing required attributes from the one to be authenticated. To achieve the property of traceability, required attributes should be combined with the signer’s attribute private keys in order to generate a signature. In some schemes, signers’ attribute keys are related to attribute trees, so changing attribute trees will cause the regeneration of all related attribute keys. In this paper, we propose an efficient traceable ABA scheme, where the generation of signers’ attribute keys is independent from attribute trees. Thus the same set of attribute keys can be used with a …
