Virtual meetings and social isolation in COVID-19 times: transposable barriers

The Norway spruce genome sequence and conifer genome evolution
2013
Conifers have dominated forests for more than 200 million years and are of huge ecological and economic importance. Here we present the draft assembly of the 20-gigabase genome of Norway spruce (Picea abies), the first available for any gymnosperm. The number of well-supported genes (28,354) is similar to the >100 times smaller genome of Arabidopsis thaliana, and there is no evidence of a recent whole-genome duplication in the gymnosperm lineage. Instead, the large genome size seems to result from the slow and steady accumulation of a diverse set of long-terminal repeat transposable elements, possibly owing to the lack of an efficient elimination mechanism. Comparative sequencing of Pinu…
piRNAclusterDB 2.0: update and expansion of the piRNA cluster database.
2021
Abstract PIWI-interacting RNAs (piRNAs) and their partnering PIWI proteins defend the animal germline against transposable elements and play a crucial role in fertility. Numerous studies in the past have uncovered many additional functions of the piRNA pathway, including gene regulation, anti-viral defense, and somatic transposon repression. Further, comparative analyses across phylogenetic groups showed that the PIWI/piRNA system evolves rapidly and exhibits great evolutionary plasticity. However, the presence of so-called piRNA clusters as the major source of piRNAs is common to nearly all metazoan species. These genomic piRNA-producing loci are highly divergent across taxa and critically…
A Battery-free Asset Monitoring System based on RF Wireless Power Transfer
2020
In the Internet of Things (IoT) era, asset monitoring represents an appealing implementation of Wireless Sensor Networks due to the enormous benefits associated with being able to monitor and record the exact position and transportation conditions of assets, personal objects, and the like. This kind of infrastructure enables the provision of increasingly advanced services, including the ability to measure the movement speed of a monitored asset using relatively inexpensive nodes with sensing capabilities and wireless transmission and reception. These nodes would ideally employ battery-free sensors that do not require any maintenance, but conventional power supply management systems cannot s…
An Internet-based treatment for Flying Phobia using 360° images: Study protocol for a feasibility pilot study
2021
Background Flying Phobia (FP) is a prevalent disorder that can cause serious interference in a person's life. ICBT interventions have already shown their efficacy in several studies, but studies in the field of specific phobias are still scarce. Moreover, few studies have investigated the feasibility of using different types of images in exposure scenarios in ICBTs and no studies have been carried out on the role of sense of presence and reality judgement. The aim of the present study is to explore the feasibility of an ICBT for FP (NO-FEAR Airlines) using two types of images with different levels of immersion (still and navigable images). A secondary aim is to explore the potential effecti…
IoT-MAAC: Multiple Attribute Access Control for IoT environments
2020
Access Control is an important security service that should be considered in IoT environments in order to offer reliable IoT services. Access control in IoT environments concerns not only the access of IoT users to IoT services and objects, but also the access of IoT objects to IoT gateways. In this paper, we specify an access control mechanism that considers the access of IoT objects to IoT gateways in order to enhance the reliability of IoT data provided by the IoT objects. Our proposed access control mechanism, called IoT-MAAC (Multi Attribute Access Control), allows retrieving requested data from the most reliable and secured IoT objects among the available objects in the IoT environmen…
Web 2.0 and the collective intelligence
2008
In this paper, I describe a new form of collective intelligence (CI) on the Internet. It is project-like self-organization of masses of ordinary people on the Internet. These crowds emerge, define the collective problem or task by themselves, solve it, and vanish as entities. I have coined this phenomena to netcrowd ('verkkovoima' in Finnish). I compare netcrowd to other forms of CI and suggest a typology for CI types.
Crowdsourcing Fundamentals: Definition and Typology
2015
Crowdsourcing is a problem-solving and task realization model that is being increasingly used. Thanks to the possibility of harnessing the collective intelligence from the Internet; thanks to the crowdsourcing initiatives people can, for example, find a solution to a complex chemical problem, get images tagged, or get a logo designed. Due to its success and usefulness, more and more researchers have focused their interest on this concept. This fact has shown that the concept of crowdsourcing has no clear boundaries, and although over time the concept has been better explained, some authors describe it differently, propose different types of crowdsourcing initiatives, or even use contradicto…
Incidencia de factores personales y contextuales sobre el uso de los recursos tecnológicos por el alumnado en América Latina
2021
El uso de las tecnologías de la información y de la comunicación (TIC) por parte de alumnado refleja si el proceso de integración es apropiado. No obstante, la tipología de uso de las TIC en el alumnado no se ha establecido de forma empírica en función de su uso en casa y el centro educativo. Así, el propósito del artículo es determinar la estructura del uso de las TIC por parte del alumnado, junto con la influencia de factores personales y contextuales. Se ha empleado un diseño correlacional, siendo la muestra el alumnado de sexto curso de América Latina que ha respondido al cuestionario sobre uso de las TIC en el Tercer Estudio Regional Comparativo y Explicativo (TERCE). El análisis de da…
Difusión online de las agendas partidistas en campaña electoral. El uso de internet en las Elecciones Locales de 2015 en la ciudad de Valencia
2015
Los objetivos de la investigación son, por una parte, analizar el uso que los partidos políticos y sus candidatos realizan de las posibilidades de interacción y difusión del mensaje brindadas por las principales redes sociales en una campaña electoral y, por otra, estudiar la composición y la transmisión de las agendas partidistas durante dicho periodo a través de las páginas web de los partidos y candidatos, de las redes sociales y de los principales cibermedios, tanto ediciones online de diarios impresos como nativos digitales. En concreto, el trabajo se centra en la actividad que desarrollaron durante la campaña de las Elecciones Locales de 2015 en la ciudad de Valencia cinco formaciones…
