Labour market assimilation of immigrants in Spain: employment at the expense of bad job-matches?
Spain has traditionally been known as a country of emigrants. However, in the last decade, Spain has experienced an unprecedented boom of immigration from three localized areas: Latin America, Africa and East Europe. In this paper, we study the behaviour of recent immigrants in the Spanish labour market identifying the major differences with the native population and tracking whether these differences fade away as their years of residence in Spain increase. With this objective, we focus on four labour market outcomes: labour supply, unemployment, incidence of overeducation and incidence of temporary contracts. Results show that, compared to natives, immigrants face initially higher participation rates, higher unemployment rates, higher incidence of overeducation and higher incidence of temporary contracts. However, five years after their arrival we could broadly say that participation rates start to converge to native rates, unemployment rates decrease to levels even lower than those of natives, and the incidence of temporary contracts and overeducation remains constant: no reduction of the gap with Spanish workers is observed. Therefore, we conclude that the Spanish labour market is managing to absorb the so called, 'immigration boom ', but at the expense of allocating immigrants in bad job-matches.immigration; assimilation; labor force participation; unemployment; overeducation; temporary contracts;
The impact of immigration on the wage structure : Spain 1995-2002
In this paper we estimate the impact of inward migration flows on the Spanish wage
structure over the period 1995-2002 by constructing counterfactual wage distributions
that provide the wages that would have been observed had individual and job
characteristics remain constant over time. Hence, we compute the impact of
immigration on the wage distribution from (i) the estimated wage gaps between similar
immigrants and native workers and (ii) the changes in the composition of employment
associated to the arrival of new immigrants.
Overall, we find that (i) the effects of immigration on wage changes are small and only
noticeable when job characteristics are included as determinants of wages, and (ii) the
correlation between the incidence of immigration in each decile of the wage distribution
and the change in native wages not explained by changes in their individual and job
characteristics is positive. These results suggest that other factors, besides immigration,
should be identified as the key determinants of the wage moderation observed since the
early nineties in Spain
The effect of immigration on the employment opportunities of native-born workers : some evidence for Spain
Spain is one of the European countries where immigration flows during the last decade have increased noticeably. The Spanish labor market institutions and the Spanish immigration policy exhibit some peculiarities which may be relevant when analyzing the impact of immigration. This paper provides a first approximation to the labor market effects of immigrants in Spain during the second half of the 1990s, the period in which immigration flows to Spain have accelerated. By using alternative datasets, we estimate both the impact of legal and total immigration flows on the employment rates of native workers, accounting for the possible occupationa l and geographical mobility of immigrants and native-born workers. Using different samples and estimation procedures, we have not found a significant negative effect of immigration on the employment rates of native workers. The corresponding estimated elasticity is low, around -0.1, when considering only legal immigrants, and is not significant when considering both legal and illegal immigrants
Reactivity indexes for different geometries of palladium leads
Electronic transport through metallic break junctions or molecules is clearly dependent not only on the electronic structure of the central nanodevice connecting the leads, but also the shape and crystalline orientation of the contacts which can define the possible conduction channels. In this work we examine different geometries of contacts of palladium characterizing them through global and local reactivity indexes as electrophilicity, chemical hardness and Fukui functions. In molecules, these indicators are essentially defined by the energies of the frontier molecular orbitals and in solids they are related with the local and partial density of states. We use for this purpose an ab-initio based code (FIREBALL), applied to plane contacts with (001) fcc faces and also pyramidal tips grown following a (001) and (111) packaging. The results allow us to have an insight about the chemical features of this type of nanojunctions.Fil: GĂłmez Carrillo, Sandra Carolina. Universidad Nacional del Litoral.

InmigraciĂłn y mercado de trabajo
Espainia da azken hamarkadan emigrante edo etorkinen fluxuan gorakadarik handienetakoa izan duen
Europako herrialdea. Horren aurrean, ez da harritzekoa inmigrazioaren fenomenoa eztabaida publikoko gai
garrantzitsuenen artean egotea, eta fenomeno horren ezaugarriak eta ondorio sozio-ekonomikoak aztertzeko
modua emango digun informazioaren eskaria asko ugaritzea. Gaur egungo testuinguruan, artzkulu honen
helburua bikoitza da: biztanleria inmigranteak Espainian duen egoera laborala aztertzea, batetik, eta
inmigranteek lan-merkatu espainiarrean eragiten dituzten ondorioen lehen hurbilketa bat eskaintzea, bestetikEspaña es uno de los paĂses europeos donde los flujos de inmigrantes han aumentado de forma mĂĄs
notable durante la Ășltima dĂ©cada. Ante esto, no resulta extraño que el fenĂłmeno de la inmigraciĂłn se haya
convertido en uno de los principales temas de debate pĂșblico y que exista una fuerte demanda de
informaciĂłn que permita analizar sus caracterĂsticas y sus consecuencias socioeconĂłmicas. En el contexto
actual, el objetivo de este artĂculo es, por un lado, estudiar la situaciĂłn laboral de la poblaciĂłn inmigrante

mercado de trabajo españo
Creando espacios para conocer la américa latina profunda
En la sociedad donde la UNILA actĂșa es prioridad crear espacios donde puedan converger personas que tengan interĂ©s en estudios teĂłricos sobre la historia, cultura y polĂtica de los paĂses en AmĂ©rica Latina, actualmente el foco de la actividad es sobre MĂ©xico. Es indispensable la construcciĂłn de campos que tengan como objetivo valorizar los mĂșltiples saberes socio-culturales en compañĂa de un proceso educativo, interdisciplinar, cientĂfico y polĂtico de lenguaje no-acadĂ©mico, que comparta la pluralidad de discurso y que a travĂ©s de ese conocimiento, fomente un intercambio cientĂfico y cultural en la triple frontera en su relaciĂłn con el resto de paĂses de AmĂ©rica Latina y en este momento, sobre MĂ©xico. La idea es estimular procesos de producciĂłn y difusiĂłn de conocimiento crĂtico frente a diversos temas que enfrenta el subcontinente y sobre la realidad brasileña, por medio del contraste con el resto de paĂses. Las actividades donde se concretan las ideas son variadas, van desde seminarios, palestras, videoconferencia, encuentros, reuniones, mesas redondas, etc. Se espera contribuir para el desarrollo cientĂfico y cultural de los participantes directos e indirectos de las actividades, propiciar una experiencia de estudio colectiva que estimule el interĂ©s polĂtico y desarrollar una comprensiĂłn profunda que vaya mĂĄs allĂĄ del contenido programĂĄtico de sala de aula. Estos espacios nacen en relaciĂłn a la AcciĂłn de ExtensiĂłn llamada âRealidad Latinoamericana 2018â en parcerĂa con el Programa âRealidad Latino-americanaâ de la Universidade Federal de SĂŁo Paulo, que ya ha enfocado sus estudios teĂłricos sobre Colombia y Venezuela (2014), BolĂvia y PerĂș (2015), Cuba (2016) y Chile y Argentina (2017) de esa manera buscando este año ampliar la participaciĂłn de la UNILA en estrechar lazos con otras actividades que permitan un intercambio cientĂfico
Subjetividades polĂticas juveniles e interculturalidad crĂtica
Este artĂculo recoge los hallazgos mĂĄs importantes que evidencian la configuraciĂłn de subjetividades
polĂticas, de jĂłvenes de MedellĂn y el Ărea Metropolitana, y su articulaciĂłn con la interculturalidad
crĂtica. Toma como base una investigaciĂłn cuyo objetivo fue indagar sobre las miradas que los jĂłvenes
pertenecientes a dos entidades de MedellĂn en Colombia con apuestas sociales desde las artes escĂ©nicas y
la apropiaciĂłn del conocimiento, han construido sobre sĂ mismos y sus relaciones con otros. El estudio se
planteĂł metodolĂłgicamente desde las narrativas autobiogrĂĄficas como forma de acercarse a los jĂłvenes y
sus historias. Entre los resultados principales se plantean aspectos relacionados con las formas cĂłmo se
asumen y proyectan en la acciĂłn colectiva y cĂłmo emergen allĂ oportunidades para reconocer y superar
las problemĂĄticas de desigualdad que atraviesan sus vidas. Las mĂĄs importantes conclusiones estĂĄn en
torno a cĂłmo se articulan la subjetividad polĂtica y sus tramas con la interculturalidad crĂtica desde los
escenarios juveniles en contextos urbanos como los de ciudades como MedellĂn.//This article gathers the most important findings that show the configuration of political subjectivities,
of young people from MedellĂn and the Metropolitan Area, and their articulation with critical interculturality.
It is based on an investigation whose objective was to investigate the looks that young people
belonging to two entities of MedellĂn in Colombia with social bets from the performing arts and the
appropriation of knowledge, have built on themselves and their relationships with others. The study
was raised methodologically from autobiographical narratives as a way of approaching young people
and their stories. Among the main results are aspects related to the ways in which they are assumed and
projected in collective action and how opportunities arise there to recognize and overcome the problems
of inequality that are going through their lives. The most important conclusions are about how political
subjectivity and its plots are articulated with critical interculturality from youth settings in urban contexts
such as those in cities like MedellĂn
Conventional Industrial Robotics Applied to the Process of Tomato Grafting Using the Splicing Technique
Horticultural grafting is routinely performed manually, demanding a high degree of concentration and requiring operators to withstand extreme humidity and temperature conditions. This article presents the results derived from adapting the splicing technique for tomato grafting, characterized by the coordinated work of two conventional anthropomorphic industrial robots with the support of low-cost passive auxiliary units for the transportation, handling, and conditioning of the seedlings. This work provides a new approach to improve the efficiency of tomato grafting. Six test rates were analyzed, which allowed the system to be evaluated across 900 grafted units, with gradual increases in the speed of robots work, operating from 80 grafts/hour to over 300 grafts/hour. The results obtained show that a higher number of grafts per hour than the number manually performed by skilled workers could be reached easily, with success rates of approximately 90% for working speeds around 210â240 grafts/hour
