Demographic Differentials in Facebook Usage Around the World
We use data from the Facebook Advertisement Platform to study patterns of
demographic disparities in usage of Facebook across countries. We address three
main questions: (1) How does Facebook usage differ by age and by gender around
the world? (2) How does the size of friendship networks vary by age and by
gender? (3) What are the demographic characteristics of specific subgroups of
Facebook users? We find that in countries in North America and northern Europe,
patterns of Facebook usage differ little between older people and younger
adults. In Asian countries, which have high levels of gender inequality,
differences in Facebook adoption by gender disappear at older ages, possibly as
a result of selectivity. We also observe that across countries, women tend to
have larger networks of close friends than men, and that female users who are
living away from their hometown are more likely to engage in Facebook use than
their male counterparts, regardless of their region and age group. Our findings
contextualize recent research on gender gaps in online usage, and offer new
insights into some of the nuances of demographic differentials in the adoption
and the use of digital technologies.Comment: Accepted at a poster at ICWSM 2019. Please cite the ICWSM versio
INNOSETA – Innovative training and influence on the quality of inspections. An overview of training organization in EU
Training and dissemination are key factors for the success in crop protection. The specific aspects related with the phase-use of Plant Protection Products (PPP) mainly linked to the spray technology, have been widely investigated and improved in the last years. A large list of research, extension and training projects supported by public funds have derived in a large list of developments, materials, tools, decision support systems and other interesting tools addressed to stakeholders (farmers, advisors, authorities…). Additionally, new developments and applied research carried out by sprayer’s manufactures have been really impressive in the last years, being able to put into the market interesting developments and technologies for a safe and efficiency use of pesticides. However, in most cases, most of those developments never arrive to the final user, due to problems linked with lack of information, limited knowledge and practical difficulties as language. INNOSETA project, a European Project financed by H2020 program has been launched with the aim to create a universal platform were stakeholders can find, on an easy and practice way, all the materials already developed, considering practical aspects as crop, regional characteristics, language, level of complexity and other important aspects.Training and dissemination are key factors for the success in crop protection.

Inspector’s training and influence on the quality of inspections. An overview of training organization in EU
Inspector’s training represents one of the most important factors affecting the effectiveness of the process. It is important to guarantee a well-trained inspector to offer a clear, objective and useful service to the farmers. But not only inspector’s training is important for the success of the global process. In order to guarantee a good dissemination of the knowledge, CHAFEA (Consumers, Health and Food European Agency) launched BTSF training courses (Better Training for Safer Food) focused on inspection and calibration of pesticide application equipment. This paper shows the experience and results after 12 three-days training courses where more than 400 official stakeholders have been trained. Great differences have been observed in the last years in the organization, contents and procedure of the inspector’s training at different EU members. In order to have an objective overview of the situation, a survey was conducted among all the EU members, through more than 200 attendants to BTSF training courses. Results will be presented in this paper.Inspector’s training represents one of the most important factors affecting the effectiveness of the process.

Propuesta metodológica de evaluación de impacto social a través de los cambios en el entorno construido
En el sur de Senegal, al igual que sucede en otras comunidades en vÃas de desarrollo, se está produciendo un cambio social que puede ser observado mediante la transformación del hábitat tradicional al moderno. Ese cambio, implica a su vez toda una serie de efectos ambientales, económicos, sociales y culturales. El objetivo de esta investigación integrada en el proyecto anteriormente mencionado, consiste en realizar una propuesta metodológica de Evaluación de Impacto Social (EIS) en la que se evalúen los impactos derivados de la transición del hábitat tradicional (Modelo 0) al hábitat modernizado (Modelo 1), con la finalidad de transmitir a la propuesta realizada por los arquitectos cooperantes (Modelo 2) la información obtenida. El Modelo 2, tiene el objetivo de integrar en los saberes constructivos tradicionales, los avances técnicos actuales y asà construir una vivienda de mayor eficiencia tecno-ambiental y enraizada con la cultura local. Esta investigación pretende dotar a la propuesta de eficiencia energética, las dimensiones socio-culturales, económicas y socioambientales inherentes a los modelos constructivos que la comunidad considere positivos. Seguidamente, se transferirá el diagnóstico al equipo de arquitectos cooperantes con la finalidad de realizar un propuesta integral que permita un mayor grado de entendimiento y adecuación a las necesidades actuales de la comunidad
Proyecto INNOSETA: Acercando la ciencia al campo para una protección de cultivos segura y sostenible
El principal objetivo del proyecto INNOSETA es el desarrollo de una plataforma o red temática que contribuya a acercar la ciencia al sector profesional, poniendo a su alcance de forma fácil todos los desarrollos derivados de la investigación, el desarrollo industrial o los últimos avances en materia de
formación relacionados todos ellos con el uso de los productos fitosanitarios.
Los beneficios esperados del desarrollo del proyecto están relacionados con
un mejor y más seguro uso de los productos fitosanitarios, la reducción de los
inputs (agua, tiempo, combustible, …) lo que redundará en un mejor aprovechamiento de los mismos, una reducción del riesgo de contaminación y una aproximación a lo establecido en la Directiva de Uso Sostenible de PlaguicidasPostprint (published version
Analytical Expressions for Radiative Opacities of Low Z Plasmas
In this work we obtain analytical expressions for the radiative opacity of several low Z plasmas (He, Li, Be, and B) in a wide range of temperatures and densities. These formulas are obtained by fitting the proposed expression to mean opacities data calculated by using the code ABAKO/ RAPCAL. This code computes the radiative properties of plasmas, both in LTE and NLTE conditions, under the detailed-level-accounting approach. It has been successfully validated in the range of interest in previous works
Single restraint stress sensitizes acute chewing movements induced by haloperidol, but not if the 5-HT agonist 8-OH-DPAT is given prior to stress
Ponencia incluida en las II Jornadas Andaluzas de Calidad de la Enseñanza Universitaria. Desarrollo de planes de calidad para la Universidad celebradas el 7 de marzo del año 2000 en SevillaThe objective of this study was two-fold: ( i) to analyze behavioral sensitization to haloperidol 2 weeks after single restraint stress, and
( ii) to establish the effects of 8-OH-DPAT treatment prior to stress on sensitized behavioral responses. Overall behavior was analyzed and
not only catalepsy, but also sedation immobility, grooming, exploration and vacuous chewing movements were evaluated. Results indicated that single restraint stress induced a long-lasting sensitization of acute vacuous chewing movements induced by haloperidol (0.25, 0.5 mgrkg i.p) Interestingly, this behavioral sensitization was prevented by 8-OH-DPAT (0.35 mgrkg s.c.) prior to stress. Finally, haloperidol-induced sedation was not disrupted by either restraint stress or 8-OH-DPAT treatment.Junta de AndalucÃa, ConsejerÃa de Educación y Cienci
What to be considered when you buy a sprayer: the SPISE advice
Since the publication of European Directive (2009/127/EC), environmental requirements for new orchard sprayers are mandatory. Only equipment which has successfully accomplish the specifications can be placed into the EU market. For this purpose, the new harmonized ISO 16119 series represents an interesting tool to fulfil the requirements. However, not all the sprayers placed in the marked after the publication of the Directive are in line with it. SPISE community has developed a practical guideline in order to guarantee a clear and universal dissemination among farmers and other stakeholders about the main requirements to be accomplished by the sprayers.Since the publication of European Directive (2009/127/EC), environmental requirements for new orchard sprayers are mandatory.
