CO2 flux emissions from the Earth's most actively degassing volcanoes, 2005-2015
2019
AbstractThe global carbon dioxide (CO2) flux from subaerial volcanoes remains poorly quantified, limiting our understanding of the deep carbon cycle during geologic time and in modern Earth. Past attempts to extrapolate the global volcanic CO2 flux have been biased by observations being available for a relatively small number of accessible volcanoes. Here, we propose that the strong, but yet unmeasured, CO2 emissions from several remote degassing volcanoes worldwide can be predicted using regional/global relationships between the CO2/ST ratio of volcanic gases and whole-rock trace element compositions (e.g., Ba/La). From these globally linked gas/rock compositions, we predict the CO2/ST gas…
Co-regulation of paralog genes in the three-dimensional chromatin architecture.
2016
Paralog genes arise from gene duplication events during evolution, which often lead to similar proteins that cooperate in common pathways and in protein complexes. Consequently, paralogs show correlation in gene expression whereby the mechanisms of co-regulation remain unclear. In eukaryotes, genes are regulated in part by distal enhancer elements through looping interactions with gene promoters. These looping interactions can be measured by genome-wide chromatin conformation capture (Hi-C) experiments, which revealed self-interacting regions called topologically associating domains (TADs). We hypothesize that paralogs share common regulatory mechanisms to enable coordinated expression acco…
Native arbuscular mycorrhizal symbiosis alters foliar bacterial community composition.
2017
The effects of arbuscular mycorrhizal (AM) fungi on plant-associated microbes are poorly known. We tested the hypothesis that colonization by an AM fungus affects microbial species richness and microbial community composition of host plant tissues. We grew the grass, Deschampsia flexuosa in a greenhouse with or without the native AM fungus, Claroideoglomus etunicatum. We divided clonally produced tillers into two parts: one inoculated with AM fungus spores and one without AM fungus inoculation (non-mycorrhizal, NM). We characterized bacterial (16S rRNA gene) and fungal communities (internal transcribed spacer region) in surface-sterilized leaf and root plant compartments. AM fungus inoculat…
Discursive framing and organizational venues: mechanisms of artificial intelligence policy adoption
2021
The purpose of this article is twofold: to theoretically assess ideational and organizational explanatory factors in the adoption of artificial intelligence policies; and to examine the extent to which the European Union has managed to facilitate a coordinated artificial intelligence policy in the Nordic countries. The study utilizes a mixed-methods approach based on systematic web searching, systematic policy document analysis and key informant semi-structured interviews. The study finds that the European Union has utilized framing-based strategies to set an agenda for a coordinated European artificial intelligence policy. Moreover, the strategy has affected member-state artificial intell…
People with Disabilities and Disasters
2017
Investigations have collectively established that disasters affect people with disabilities both disproportionately and negatively. In addition, perceived disability status is often associated with stigma, creating a separate and unique barrier across societies and cultures, which can augment vulnerability to disasters. Relevant research is reviewed by academic genesis areas in this chapter, namely; 1) disaster-focused research, 2) mental health, 3) epidemiology and public health, and 4) disability studies. Research emanating from these disciplines reflects different epistemological assumptions about disability as well as varying knowledge about disability as a social and cultural const…

Deliberación celérica desde la periferia
2005
Análisis sobre el consumo de medios y los usos telemáticos que los españoles desplegaron entre el 11-M y el 14-M. Consideramos los días correlativos de la semana previa, la primera de la campaña electoral, para establecer qu medios aumentaron más su audiencia y experimentaron mayor flujo de información. Veremos cómo se alteró la esfera pública para generar un nuevo proceso de "formación de opiniones" celérico

Medios digitales, transmisión de información y formación del espacio público: comunicación de masas y comunicación en red ante el 11M
2004
En los días transcurridos entre el atentado del 11M y las elecciones del 14M se vivió en España un intenso debate en torno a la autoría de los atentados que tuvo una incidencia difícil de determinar en las elecciones. Un debate cuyo punto de partida, a su vez, constó de dos condicionantes principales: primero, las diferentes estrategias informativas de Gobierno y oposición, así como los diversos medios de comunicación, en cuanto a la autoría del atentado, y segundo, la sobreinformación del público, a través tanto de los medios de comunicación de masas tradicionales como de medios de información alternativos (televisiones por cable, canales temáticos, la Internet) e interpersonales (principa…
Ajatuksella ja ahkeruudella kolmen suvun vaiheista neljältä vuosisadalta
