RINEX_HO: second- and third-order ionospheric corrections for RINEX observation files

When GNSS receivers capable of collecting dual-frequency data are available, it is possible to eliminate the first-order ionospheric effect in the data processing through the ionosphere-free linear combination. However, the second- and third-order ionospheric effects still remain. The first-, second- and third-order ionospheric effects are directly proportional to the total electron content (TEC), although the second- and third-order effects are influenced, respectively, by the geomagnetic field and the maximum electron density. In recent years, the international scientific community has given more attention to these kinds of effects and some works have shown that for high precision GNSS positioning these effects have to be taken into consideration. We present a software tool called RINEX_HO that was developed to correct GPS observables for second- and third-order ionosphere effects. RINEX_HO requires as input a RINEX observation file, then computes the second- and third-order ionospheric effects, and applies the corrections to the original GPS observables, creating a corrected RINEX file. The mathematical models implemented to compute these effects are presented, as well as the transformations involving the earth's magnetic field. The use of TEC from global ionospheric maps and TEC calculated from raw pseudorange measurements or pseudoranges smoothed by phase is also investigated.

Modelli Gravitazionali per l'analisi del Commercio Internazionale

Il modello gravitazionale e' ormai diventato un "cavallo da battaglia" in economia internazionle ed e' comunemente utilizzato nella determinazione dei flussi commerciali. Recentemente, molti studi hanno mostrato l'importanza della dipendenza spaziale, che va' a considerare quegli effetti dovuti al cosiddetto "third country". Intervengono a questo scopo la modellistica e le tecniche di stima di Econometria Spaziale. Verra' fatto uso di tali tecniche allo scopo di stimare con un modello gravitazionale spaziale il commercio internazionale tra paesi dell'OCSE per un panel di 22 anni. L'obiettivo e' quindi duplice: da un lato, si andra' ad applicare le piu' moderne tecniche di Econometria Spaziale, in un campo in cui tali contributi scarseggiano. Dall'altro lato,verra' fornita una interpretazione del comportamento del commercio internazionale tra paesi dell'OCSE, approfondendo gli aspetti relativi all'effetto del"third country" e del fenomeno migratorio. Inoltre , viene proposta un'analisi che ha lo scopo di validare l'ipotesi di omissione della distanza dal modello gravitazione strutturale.

Labour Mobility in Europe: An untapped resource? CEPS Policy Brief No. 327, March 2015

Despite public perceptions, labour mobility is low in the EU, particularly within the euro area. The authors of this Policy Brief make four main points: first, that the economic and financial crisis has affected mobility patterns by redirecting flows away from the periphery, thus showing the limits of labour mobility potential within the current eurozone - largely due to the negligible mobility of nationals from large countries hit by the crisis. Second, east-west mobility has not been fundamentally affected by the crisis, and ten years after the eastern enlargement the number of East Europeans living in EU15 should be of no overall concern. Third, the long-term economic effects of mobility are uncertain, but potential negative effects are more likely to show up in sending countries than in receiving ones. Finally, in view of the lessons learned from the economic crisis, the Commission and member states should adopt a longer-term view on labour mobility. The authors recommend a further upgrade of job-matching tools, namely the EURES system, and should foster better recognition of qualifications and the exchange of best practices among mobility networks. In order to improve mobility in the longer term, the Commission and member states should improve the mobility of third-country nationals – starting with those completing tertiary education at an EU institution and able to find employment. The aim of improving mobility gives new impetus to the ‘mother tongue + two foreign languages’ objective and the European Benchmark of Language Competences Initiative, in particular competence in the first foreign language taught at school.

Bringing protection home : healing the schism between international obligations and national safeguards created by extraterritorial processing

Extraterritorial processing schemes are designed to prevent and deter access to statutory and judicial safeguards in the country responsible for the interception and transfer of asylum seekers to a third country. In line with this objective, they incorporate interdiction, transfer and processing practices and standards that are deliberately isolated from the national legal and institutional protections within either the intercepting state or the third country where processing occurs. Australia's recent disbandment of its extraterritorial processing centres in third countries highlights the fact that extraterritorial processing schemes have proven unworkable as a matter of international law, as they negate the national safeguards fundamental to the satisfaction of a state's protection obligations.

Egg production in furnished cages

In the European Union, conventional cages for laying hens will be faded out at the beginning of 2012. The rationale behind this is a public concern over animal welfare in egg production. As alternatives to conventional cages, the European Union Council Directive 1999/74/EC allows non-cage systems and enriched (furnished) cages. Layer performance, behavior, and welfare in differently sized furnished cages have been investigated quite widely during recent decades, but nutrition of hens in this production system has received less attention. This thesis aims to compare production and feed intake of laying hens in furnished and conventional cages and to study the effects of different dietary treatments in these production systems, thus contributing to the general knowledge of furnished cages as an egg production system. A furnished cage model for 8 hens was compared with a 3-hen conventional cage. Three consecutive experiments each studied one aspect of layer diet: The first experiment investigated the effects of dietary protein/energy ratio, the second dietary energy levels, and the third the effects of extra limestone supplementation. In addition, a fourth experiment evaluated the effects of perches on feed consumption and behavior of hens in furnished cages. The dietary treatments in experiments 1 3 generally had similar effects in the two cage types. Thus, there was no evidence supporting a change in nutrient requirements for laying hens when conventional cages are replaced with small-group furnished cages. Moreover, the results from nutritional experiments conducted in conventional cages can be applied to small-group furnished cage systems. These results support the view that production performance comparable with conventional cages can be achieved in furnished cages. All of the advantages of cages for bird welfare are sustained in the small-group furnished cages used here. In addition, frequent use of perches and nests implies a wider behavioral repertoire in furnished cages than in conventional cages. The increase observed in bone ash content may improve bird welfare in furnished cages. The presence of perches diminished feed consumption during the prelaying period and enhanced the feed conversion ratio during the early laying period in furnished cages. However, as the presence or absence of perches in furnished cages had no significant effect on feed consumption after the prelaying period, the lower feed consumption observed in furnished cages than in conventional cages could be attributed to other factors, such as the presence of wood shavings or a nest box. The wider feed trough space per hen in conventional than in furnished cages may partly explain the higher feed consumption observed in conventional cages.

Migration-Development Nexus in the Malawian Health Sector: European Union Blue Card – circular migration for development?

The European Union has agreed on implementing the Policy Coherence for Development (PCD) principle in all policy sectors that are likely to have a direct impact on developing countries. This is in order to take account of and support the EU development cooperation objectives and the achievement of the internationally agreed Millennium Development Goals. The common EU migration policy and the newly introduced EU Blue Card directive present an example of the implementation of the principle in practice: the directive is not only designed to respond to the occurring EU labour demand by attracting highly skilled third-country professionals, but is also intended to contribute to the development objectives of the migrant-sending developing countries, primarily through the tool of circular migration and the consequent skills transfers. My objective in this study is to assess such twofold role of the EU Blue Card and to explore the idea that migration could be harnessed for the benefit of development in conformity with the notion that the two form a positive nexus. Seeing that the EU Blue Card fails to differentiate the most vulnerable countries and sectors from those that are in a better position to take advantage of the global migration flows, the developmental consequences of the directive must be accounted for even in the most severe settings. Accordingly, my intention is to question whether circular migration, as claimed, could address the problem of brain drain in the Malawian health sector, which has witnessed an excessive outflow of its professionals to the UK during the past decade. In order to assess the applicability, likelihood and relevance of circular migration and consequent skills transfers for development in the Malawian context, a field study of a total of 23 interviews with local health professionals was carried out in autumn 2010. The selected approach not only allows me to introduce a developing country perspective to the on-going discussion at the EU level, but also enables me to assess the development dimension of the EU Blue Card and the intended PCD principle through a local lens. Thus these interviews and local viewpoints are at the very heart of this study. Based on my findings from the field, the propensity of the EU Blue Card to result in circular migration and to address the persisting South-North migratory flows as well as the relevance of skills transfers can be called to question. This is as due to the bias in its twofold role the directive overlooks the importance of the sending country circumstances, which are known to determine any developmental outcomes of migration, and assumes that circular migration alone could bring about immediate benefits. Without initial emphasis on local conditions, however, positive outcomes for vulnerable countries such as Malawi are ever more distant. Indeed it seems as if the EU internal interests in migration policy forbid the fulfilment of the PCD principle and diminish the attempt to harness migration for development to bare rhetoric.

Fangquoten für die EU-Mitgliedsländer 1998

The fishery ministers of the EU agreed in their yearly pre-Christmas marathon session on 18th and 19th Dec. 1997 on next year’s TACs and country quota. Main decision was the increase of the TAC for North sea cod and a smaller than feared cut of cod TACs in the West of Scotland zone, the Irish Sea and the English Channel. For the first time ministers set country quota for horse mackerel; until 1997 there had been - with the exception for Portugal and Spain - only a common quota. Also for the much disputed sandeel fishery a TAC of 1 mio. t was finally established, as well as for bluefin tuna and swordfish in the Atlantic and Mediterranean. For 1998 the EU member countries dispose of a total catch quota of 4.46 mio. t in EU waters, and together with quota in third country waters of 5.2 mio. t. Of this total quota, 3.16 mio. t are fish for human consumption and 2.1 mio. t fish for industrial purposes.

Unraveling EU Policies: the ““Common Basic Principles”” and the ““European Integration Fund”” as a technology of government

this paper is about EU “soft policies” on immigrant integration. It analyzes the “Common Basic Principles” (CBPs) and the “European Integration Fund” (EIF), two devices that have been recently established within this framework. It adopts the theoretical perspective of the “anthropology of policy” and “governmentality studies”. It shows the context of birth of the aforementioned devices, as well as their functioning and the assessment done by the actors implied in the elaboration/implementation/evaluation of the related policies. It is based both on documentary research as well as direct observation and interviews done to the actors implied. It concludes that the PBC and the EIF should be considered as a “technology of government”, that strives to align the conduct of the actors with the governmental aims, as well as it produces specific practices and knowledge. It also underlines an intrinsic feature of many policies: their “congenital failure”, since they are (often) disputed and resignified by situated actors, who are embedded in asymmetrical power relations.

Explaining levels of deprivation in the European Union

In this paper we seek to explain variations in levels of deprivation between EU countries. The starting-point of our analysis is the finding that the relationship between income and life-style deprivation varies across countries. Given our understanding of the manner in which the income-deprivation mismatch may arise from the limitations of current income as a measure of command over resources, the pattern of variation seems to be consistent with our expectations of the variable degree to which welfare-state regimes achieve 'decommodification' and smooth income flows. This line of reasoning suggests that cross-national differences in deprivation might, in significant part, be due not only to variation in household and individual characteristics that are associated with disadvantage but also to the differential impact of such variables across countries and indeed welfare regimes. To test this hypothesis, we have taken advantage of the ECHP (European Community Household Panel) comparative data set in order to pursue a strategy of substituting variable names for country/welfare regime names. We operated with two broad categories of variables, tapping, respectively, needs and resources. Although both sets of factors contribute independently to our ability to predict deprivation, it is the resource factors that are crucial in reducing country effects. The extent of cross-national heterogeneity depends on specifying the social class and situation in relation to long-term unemployment of the household reference person. The impact of the structural socio-economic variables that we label 'resource factors' varies across countries in a manner that is broadly consistent with welfare regime theory and is the key factor in explaining cross-country differences in deprivation. As a consequence, European homogeneity is a great deal more evident among the advantaged than the disadvantaged.

Swimming against the tide:Outward staffing flows from multinational subsidiaries

Studying the flows of parent country nationals in multinational enterprises (MNEs) to subsidiary operations has a relatively long tradition. Studying flows of subsidiary employees to other subsidiaries, as third country nationals, and to the corporate headquarters, as inpatriates, however, has empirically much less pedigree. Drawing on a large-scale empirical study of MNEs in Ireland, this paper provides a benchmark of outward flows of international assignees from the Irish subsidiaries of foreign-owned MNEs to both corporate headquarters and other worldwide operations. Building on insights from the resource-based view and neo-institutional theory, we develop and test a theoretical model to explain outward staffing flows. The results show that almost half of all MNEs use some form of outward staffing flows from their Irish operations. Although the impact of specific variables in explaining inter-organization variation differs between the utilization of inpatriate and third country national assignments, overall we find that a number of headquarters, subsidiary, structural, and human resource systems factors emerge as strong predictors of outward staffing flows. © 2010 Wiley Periodicals, Inc.

Taxation and Household Financial Decisions: Evidence from the Bush Tax Acts

Thesis (Ph.D.)--University of Washington, 2013

Separating sequential equilibrium in a Bayesian international duopoly

We consider two Cournot firms, one located in the home country and the other in the foreign country, producing substitute goods for consumption in a third country. We suppose that neither the home government nor the foreign firm know the costs of the home firm, while the foreign firm cost is common knowledge. We determine the separating sequential equilibrium outputs.

La comparaison entre les ressortissants travailleurs turcs et les citoyens de l'UE concernant leur protection contre l'expulsion de l'Union Européenne.

Dans l’Union européenne, certaines catégories d’immigrants font l’objet d’une protection renforcée contre l’expulsion. Cette protection contre l’expulsion s’acquiert notamment après avoir résidé de manière continue et pour une longue durée dans un État membre de l’Union européenne, de sorte que son intégration y soit forte. Qu’est ce que la notion de protection renforcée contre l’expulsion signifie exactement? Nous examinerons le droit de l’UE, en comparant le droit à la libre circulation des ressortissants européens et des travailleurs turcs, et l’étendue de leur protection respective contre l’expulsion. Est-elle la même ? Pour répondre à cette question, nous verrons le droit applicable à chacune de ces catégories de citoyens, notamment la Directive 2004/38/CE du Parlement européen et du Conseil, du 29 avril 2004, relative au droit des citoyens de l’Union et des membres de leurs familles de circuler et de séjourner librement sur le territoire des États membres, le droit d’association UE/Turquie ainsi que la Directive 2003/109/CE du Conseil du 25 novembre 2003 relative au statut des ressortissants de pays tiers résidents de longue durée. Cette protection diffère selon la citoyenneté des individus. Ainsi, la protection des ressortissants turcs est moindre que celle des ressortissants européens. Toutefois, la CJUE a joué un rôle proactif dans l’interprétation des droits à la libre circulation des travailleurs turcs, en interprétant le droit d’association Turquie/UE par analogie avec celui applicable aux citoyens européens. Dans les litiges relatifs à la protection contre l’expulsion, les travailleurs turcs se sont également vu reconnaître une protection semblable à celle des ressortissants européens par la CJUE. La Convention européenne des droits de l’homme est un autre instrument qui vient protéger les résidants de l’Europe contre une violation de leurs droits fondamentaux que pourrait entraîner une expulsion du territoire. Face à cet activisme judiciaire, on est en mesure de se demander dans quelle mesure les ressortissants travailleurs turcs et européens jouissent d’une protection différente contre l’expulsion.

Análisis del papel político de Egipto en el conflicto Israel Palestina: Durante el período 2003 2008

El conflicto entre Israel y Palestina es uno de lo más prolongados y relevantes para la configuración de la región de Medio Oriente, a razón de su componente religioso, social, político e influencia a nivel internacional. Es por esto que es pertinente analizarlo desde diferentes perspectivas, en este caso desde el papel que desempeña un tercer Estado como Egipto, que a razón de su cercanía geográfica al compartir fronteras, a los intereses políticos y a la estrecha relación que la dinámica histórica y geopolítica genera, ha sido uno de los participantes más activos y constantes en este conflicto. El rol que Egipto ha desempeñado ha variado con el tiempo, pasando de ser un actor incitador del conflicto a convertirse en mediador del mismo. La descripción y análisis de los factores que influyen en la transformación egipcia, permiten al lector comprender como a pesar de su contexto socio político interno, Egipto poco a poco ha optado por llevar acabo estrategias mucho más moderadas frente al conflicto.

Implicaciones del concepto de ciudadanía europea para el estatus político de los residentes legales nacionales de terceros estados en el marco supranacional

Dar algunas luces sobre el ya viejo, aún irresuelto conflicto entre ciudadanía y nacionalidad3. Hemos escogido el caso europeo porque consideramos que las dinámicas transnacionales que afectan a Europa hacen visible la insuficiencia del concepto tradicional, atado al Estado nacional.
