Cross-country polarisation in CO2 emissions per capita in the European Union: changes and explanatory factors
In this study, we analyse the degree of polarisation—a concept fundamentally different from that of inequality—in the international distribution of CO2 emissions per capita in the European Union. It is analytically relevant to examine the degree of instability inherent to a distribution and, in the analysed case, the likelihood that the distribution and its evolution will increase or decrease the chances of reaching an agreement. Two approaches were used to measure polarisation: the endogenous approach, in which countries are grouped according to their similarity in terms of emissions, and the exogenous approach, in which countries are grouped geographically. Our findings indicate a clear decrease in polarisation since the mid-1990s, which can essentially be explained by the fact that the different groups of countries have converged (i.e. antagonism among the CO2 emitters has decreased) as the contribution of energy intensity to between-group differences has decreased. This lower degree of polarisation in CO2 distribution suggests a situation more conducive to the possibility of reaching EU-wide agreements on the mitigation of CO2 emissions.CO2 emissions, distribution of emissions, European Union, mitigation agreements, polarisation.
EXPLANATORY FACTORS OF CO2 PER CAPITA EMISSION INEQUALITY IN THE EUROPEAN UNION
The design of European mitigation policies requires a detailed examination of the factors explaining the unequal emissions in the different countries. This research analyzes the evolution of inequality in CO2 per capita emissions in the European Union (EU-27) in the 1990–2006 period and its explanatory factors. For this purpose, we decompose the Theil index of inequality into the contributions of the different Kaya factors. The decomposition is also applied to the inequality between and within groups of countries (North Europe, South Europe, and East Europe). The analysis shows an important reduction in inequality, to a large extent due to the smaller differences between groups and because of the lower contribution of the energy intensity factor. The importance of the GDP per capita factor increases and becomes the main explanatory factor. However, within the different groups of countries the carbonization index appears to be the most relevant factor in explaining inequalities.CO2 emissions, emission inequality, European Union, Kaya factors, Theil index.
Inequality across countries in energy intensities: an analysis of the role of energy transformation and final energy consumption
This paper analyzes the role of the energy transformation index and of final energy consumption per GDP unit in the disparities in energy intensity across countries. In that vein, we use a Theil decomposition approach to analyze global primary energy intensity inequality as well as inequality across different regions of the world and inequality within these regions. The paper first demonstrates the pre-eminence of divergence in final energy consumption per GDP unit in explaining global primary energy intensity inequality and its evolution during the 1971–2006 period. Secondly, it shows the lower (albeit non negligible) impact of the transformation index in global primary energy inequality. Thirdly, the relevance of regions as unit of analysis in studying crosscountry energy intensity inequality and their explanatory factors is highlighted. And finally, how regions around the world differ as to the relevance of the energy transformation index in explaining primary energy intensity inequality.Energy efficiency, energy intensities, energy transformation, Theil index
The effect of the Oxytocin hormone in Cocaine addicted rats suffering from abstinence syndrome
Rehabilitation from a history of drug abuse is a very difficult and life changing process. Abstinence syndrome forces the rehabilitating patient to go through anxiety like symptoms. The Oxytocin hormone has been believed to be a potential facilitator in the rehabilitation process. This hormone is very present during interactions of affection (hugs) and birth, it foments trust while it associates to a feeling of calmness. Oxytocin would theoretically be a calming agent to the anxiety like symptoms such as craving. The experiment aimed to test the calming effects of the hormone, consisted of a five-day systemic cocaine injections treatment schedule and a sixth day of intranasal administration of Oxytocin or saline. Six Sprague-Dawley male rats were assigned to two separate groups of three: one group was given Oxytocin on the sixth day and the other was given a saline solution. Both groups were introduced to the Elevated Plus Maze (EPM) test to measure the anxiety. Throughout the first five days the locomotion was monitored and recorded. The collected data showed a constant rising of locomotion from day two through day five where is reached a peak and then lowered down, this occurred for all rats. The rats that received intranasal Oxytocin treatment spent more time in the open arms when put in the EPM test in contrast to the rats that received saline that spent more time inside the closed arms even though the difference between the groups was not significant. These results suggest that Oxytocin could possibly have anxiolytic effects
The effect of the Oxytocin hormone in Cocaine addicted rats suffering from abstinence syndrome
This study aimed to understand the effects of oxytocin in cocaine-addicted rats to prove its ability to help recovering drug addicts overcome the extreme anxiety and craving that makes them relapse during their rehabilitation
Agua, mĂşsica y delicuescencia subterránea en la poesĂa de Seamus Heane: complejos simbĂłlicos de Moyola y del zahorĂ
This article analyses two particular aspects of water symbolism in the poetry of Seamus Heaney: on the one hand, it focuses on the interrelationship between water and music in what we have termed symbolic complex of Moyola; on the other hand, it emphasizes the significance of underground water and deliquescence in what we call symbolic complex of the diviner. These two symbolic complexes show the inspirational force of water in the poetry of the Nobel prize writer. Finally, this symbolic study intertwines as well with other personal and community identity issues of utmost importance in Heaney's oeuvre
Complejos simbĂłlicos de Anteo y Atlas en la poesĂa de Seamus Heaney
En este artĂculo abordamos el estudio de la ambivalencia simbĂłlica de la tierra en la poesĂa de Seamus Heaney, y más concretamente en su poemario The Spirit Level (1996). Se analizan, de una parte, los valores sĂmbolos de Ăndole positiva dentro del que denominamos complejo simbĂłlico de Anteo. De otra, constatamos el valor negativo de la sobrecarga que no pocas veces caracteriza a la tierra en el denominado complejo simbĂłlico de Atlas. A travĂ©s de ambos opuestos / complementarios nuestro artĂculo incidirá en la dialĂ©ctica, tensiĂłn y movimiento propios de la poĂ©tica heaneyiana. This article focuses on the symbolic ambivalence of earth in the poetry of Seamus Heaney, especially in his collection The Spirit Level (1996). On the one hand, it analyses positive symbolic values within the so-called symbolic complex of Antaeus; on the other hand, the author explores in his symbolic complex of Atlas the negative value of overload which often characterizes Heaney’s earth. Through these complementary opposites, the article emphasizes such Heaneyian poetic features as dialectics, tension and movement

CRISPR/Cas9-mediated editing of the TM6 MADS-box gene in the octoploid strawberry (Fragaria x ananassa)
El contenido del poster presentado está desarrollado en: doi:10.1093/jxb/ery400 y
Publicado por Oxford University pressThe B-class of MADS-box transcription factors has been studied in many plant species, but
remain functionally uncharacterized in the Rosaceae family. APETALA3 (AP3), a member of this
class, controls the identity of petals and stamens in Arabidopsis thaliana. In this work, we identified
two members of the AP3 lineage in the cultivated strawberry (Fragaria Ă— ananassa): FaAP3
and FaTM6. Interestingly, FaTM6, and not FaAP3, shows an expression pattern equivalent to that
of AP3 in Arabidopsis. Genome editing using Cluster Regularly Interspaced Short Palindromic
Repeats (CRISPR)/Cas9 system is becoming a robust tool for targeted and stable mutagenesis
of DNA. However, whether it can be efficiently used in an octoploid species such as F. Ă— ananassa
is not known. In our study, we report the application of the CRISPR/Cas9 in F. Ă— ananassa to
characterize the function of FaTM6 in flower development. An exhaustive analysis by high-throughput
sequencing of the FaTM6 locus spanning the target sites showed a high efficiency genome
editing already in the T0 generation. The phenotypic characterization of the mutant lines
indicates that FaTM6 plays a key role in petal and especially in anther development in strawberry.
Our results validate the CRISPR/Cas9 strategy for gene functional analysis in an octoploid
species such as F. Ă— ananassa, and offer new opportunities for engineering strawberry to improve
traits of interest in breeding programs.Universidad de Málaga. Campus de Excelencia Internacional AndalucĂa Tech
