The European Map of Job Flows

The European Map of Job Flows (EMJF) is a term used to denote a dataset of meso- and macro-level variables describing different aspect of labour mobility within national labour markets in Europe. In this paper, EMJF is centred on the notion of job “flows”, namely the changes in the level of employment at different breakdowns and levels of aggregation. EMJF is very rich in information content due to the wide variety of possible breakdown of the data and in this sense it is a “map” mostly in the virtual sense, namely, that it is not possible to visualise in the form of geographic maps all the wealth of available information. In terms of its value as a research product and tool, EMJF is mostly an intermediate product in the sense that it is a convenient means to organise the relevant information, which could subsequently be used for different analytical and research purposes. It provides both for cross-sections/snapshots of job flows at different point in time but also it allows their assessment and analysis over longer periods of time. In this sense, EMJF can be widely used for various types of labour-market analysis and research. EMJF’s visual components can also be a convenient tool for policy makers dealing with labour market policies at different level (regional, national or supra-national) in the decision-making process. Here we present a Compilation of a EMJF on the basis of firm-level data In this sense the job flows are built up on the basis of firm-level data for individual countries, following a common methodology. We adopt an approach of establishing such a EMJF on the basis of the AMADEUS dataset developed by the consultancy Bureau van Dijk. The dataset in its most extended version contains balance sheet data and ownership data for almost 14 million firms from 43 different European countries (September 2009 update). For many EU countries the dataset has in principle access to the entire universe of firms which have to report a balance sheet. In terms of countries, the geographic coverage of AMADEUS encompasses information for all the 27 members of the European Union (albeit with different qualities in terms of national coverage) as well as other 16 European countries that complete the geographical and political definition of the continent. Another interesting feature of the database is given by the detailed definition of a firm's location, with data available on the region (NUTS2) and the city in which the firm operates. This project deliverable presents the main results from the final stage of MICRO-DYN work on the EMJF. It discusses the approach to building the EMJF on the basis of AMADEUS data and illustrates the analytical potential of the EMJF as a research tool with a range of Europe-wide analytical exercises. Probably the most important outcome of this research effort is the demonstrated capability to perform meta-analysis at the European level of important labour market characteristics on the basis of firm-level data.job flows, europe, labor market, microdata

Efecto del lixiviado de humus de lombriz y fertilizante químico en el desarrollo de Lilium Conca D Or con bulbos infectados con Erwinia sp.

Las lilis son flores ornamentales de las más importantes en el mundo, ya que ocupan el tercer lugar de la producción mundial de las flores de bulbo. Debido a que la calidad de flor, muy apreciada por el consumidor, es un cultivo que asegura buena demanda en el mercado. Sin embargo, a pesar de que México es un productor importante de Lilium, la producción de bulbos para siembra es escasa o nula; lo que ocasiona precios altos de venta y, en algunos casos, enfermedades en los bulbos debido a los períodos de transporte y en su almacenamiento en frío. En el Estado de México, los problemas por la pudrición del bulbo y tallo de esta flor, han causado pérdidas severas del 50 % de la producción. El agente causal de esta enfermedad no ha sido caracterizado, por lo que no se puede hacer un manejo adecuado del mismo. Se sabe, que el almacenamiento de bulbos por largo tiempo favorece la aparición de enfermedades fungosas y bacterianas que pudieran no ser detectables al momento de ser adquiridas por el productor. Otro punto importante a considerar en la producción es la fertilización, sin dejar de lado que uno de los objetivos de la agricultura actual, es el empleo de fuentes de fertilización que sean menos dañinas al ambiente. En este tenor, el presente trabajo propone “Evaluar el efecto de humus de lombriz en el desarrollo y vida postcosecha de bulbos de Lilium ‛Conca d’Or’ infectados con Erwinia sp., a la aplicación precosecha de tres diferentes fuentes de fertilización”. Se definieron los tres tratamientos con las diferentes dosis de fertilización; se aplicaron, cada 20 días, en dosis de 29 ml por planta de lixiviado de humus de lombriz. En el tratamiento, con solo fertilización química se aplicó urea, cloruro de potasio, ácido fosfórico, nitrato de calcio, nitrato de magnesio y sal común para dar concentraciones iguales al aplicado del lixiviado. Así, para el tercer tratamiento, se combinó la mitad del fertilizante químico indicado y 14.5 ml de lixiviado de humus de lombriz por planta. En bulbos de Lilium ʿConca d’Or’ contaminados con la bacteria Erwinia sp. El abonado con lixiviado de humus de lombriz redujo a menos del 10% la presencia de síntomas de esta enfermedad. La presencia de síntomas fue mayor a 50% en tallos fertilizados químicamente; mientras que la combinación (0.5:0.5) de lixiviado y fertilizante químico también redujo a 10% la aparición de síntomas. La menor presencia de la enfermedad bacteriana en los tallos abonados con lixiviado de humus de lombriz estuvo acompañado con mayor índice de verdor en las hojas y altura de planta, respecto a los tallos fertilizados químicamente. En postcosecha la adición de 2% de azúcar no fue eficiente en alargar la vida de los tallos que fueron abonados con lixiviado de humus de lombriz, incluso su longevidad se limitó con la adición de esté carbohidrato

Characterizing the Association Between Material Hardship Across Development and Connectome-Wide Brain Connectivity in Adolescents

Experiencing poverty during childhood may prompt experience-dependent neural adaptations. These manifest through functional connectivity patterns across networks thought to support cognitive and socio-emotional processing. Interrelated network connectivity disruptions have been associated with the development of internalizing disorders. Connectome-wide network characterizations of functional connectivity in adolescents who grew up in poverty are lacking. To this end, this dissertation aimed to characterize the association between family material hardship, connectome-wide network connectivity and internalizing symptoms in adolescence. The introductory chapter proposes material hardship, which directly measures a family's experiences with unmet basic needs (e.g., no access to food) as a better alternative to income-based measures used in research. Subsequently, in Chapters Two and Three, network contingency analyses were conducted to characterize connectome-wide connectivity associated with lifetime family material hardship for adolescents drawn from a national longitudinal study. Correlational analyses evaluating the association between network connectivity and current adolescent internalizing symptoms were done. Notably, the mixed findings across the two studies suggest that connectome-wide adaptations confer both cost and benefits to youth who experienced material hardship. Data suggests that altered network connectivity may be protective and that not everyone who experiences material hardship develops internalizing symptoms. In the final chapter, the limitations and implications of the present findings are discussed. Recommendations for more multi-method research to better characterize the association between brain function and poverty are made.PHDPsychologyUniversity of Michigan, Horace H.

Fourier Transforms for Generalized Fredholm Equations

In this chapter we take the conventional Fredholm integral equations as a guideline to define a broad class of equations we name generalized Fredholm equations with a larger scope of applications. We show first that these new kind of equations are really vector-integral equations with the same properties but with redefined and also enlarged elements in its structure replacing the old traditional concepts like in the case of the source or inhomogeneous term with the generalized source useful for describing the electromagnetic wave propagation. Then we can apply a Fourier transform to the new equations in order to obtain matrix equations to both types, inhomogeneous and homogeneous generalized Fredholm equations. Meanwhile, we discover new properties of the field we can describe with this new technology, that is, mean; we recognize that the old concept of nuclear resonances is present in the new equations and reinterpreted as the brake of the confinement of the electromagnetic field. It is important to say that some segments involving mathematical details of our present work were published somewhere by us, as part of independent researches with different specific goals, and we recall them as a tool to give a sound support of the Fourier transforms

Optimum Efficiency on Broadcasting Communications

This chapter is devoted to review a set of new technologies that we have developed and to show how they can improve the process of broadcasting in two principal ways: that is, one of these avoiding the loss of transmission signals due to abrupt changes in sign of the diffraction index and the other, preventing the mutual perturbation between signals generating information leak. In this manner, we propose the join of several of the mentioned technologies to get an optimum efficiency on the process of broadcasting communications showing the theoretical foundations and discussing some experiments that bring us to create the plasma sandwich model and others. Despite our very innovative technology, we underline that a complete recipe must include other currently in use like multiple-input multiple-output (MIMO) simultaneously. We include some mathematical proofs and also give an academic example

Quantitative analysis of S. mutans and S. sobrinus cultivated independently and adhered to polished orthodontic composite resins

In Orthodontics, fixed appliances placed in the oral cavity are colonized by microorganisms. OBJECTIVE: The purpose of this study was to quantitatively determine the independent bacterial colonization of S. mutans and S. sobrinus in orthodontic composite resins. MATERIAL AND METHODS: Seven orthodontic composite adhesives for bonding brackets were selected and classified into 14 groups; (GIm, GIs) Enlight, (GIIm, GIIs) Grengloo, (GIIIm, GIIIs) Kurasper F, (GIVm, GIVs) BeautyOrtho Bond, (GVm, GVs) Transbond CC, (GVIm, GVIs) Turbo Bond II, (GVIIm, GVIIs) Blugloo. 60 blocks of 4x4x1 mm of each orthodontic composite resin were made (total 420 blocks), and gently polished with sand-paper and ultrasonically cleaned. S. mutans and S. sobrinus were independently cultivated. For the quantitative analysis, a radioactive marker was used to codify the bacteria (³H) adhered to the surface of the materials. The blocks were submerged in a solution with microorganisms previously radiolabeled and separated (210 blocks for S. mutans and 210 blocks for S. sobrinus) for 2 hours at 37ºC. Next, the blocks were placed in a combustion system, to capture the residues and measure the radiation. The statistical analysis was calculated with the ANOVA test (Sheffè post-hoc). RESULTS: Significant differences of bacterial adhesion were found amongst the groups. In the GIm and GIs the significant lowest scores for both microorganisms were shown; in contrast, the values of GVII for both bacteria were significantly the highest. CONCLUSIONS: This study showed that the orthodontic composite resin evaluated in the GIm and GIs, obtained the lowest adherence of S. mutans and S. sobrinus, which may reduce the enamel demineralization and the risk of white spot lesion formation

Estimation of Metal Loss by Corrosion Process in Heat Exchangers Applied to Hydrotreating Systems

It is well known that among of all the components of hydrotreating systems used in the industrial processes, the heat exchangers that pre-heat the reactor suffer the greatest degree of degradation by pitting corrosion due to extreme temperature exposure. Typically, two different mathematical analysis were used to estimate the probability of failure by metal loss as a consequence of pitting corrosión mechanism: short-term and long-term corrosion rate (STCR and LTCR, respectively), as designated by API 510 standard method. However, the results are often misunderstood when the difference between the calculated data of STCR and LTCR is large. For this reason, in this research the STCRs and LTCRs models were fitted to a generalized extreme value distribution (GEVD) to characterize the metal loss that take place in four heat exchangers, as well as to determine what kind of corrosion rate model is better for predicting the metal loss estimation. According to the results obtained in this research, the STCR model appears to be the most appropriate analysis for estimating future metal loss by pitting corrosion for the heat exchangers reactors used in hydrotreating systems.Thanks to Secretaria de Investigación y Estudios Avanzados SIyEA/UAEM for its financial support through research projects
