Deep and Proximate Determinants of the World Income Distribution
2019
This paper studies the deep and proximate determinants of the evolution of the cross-country distribution of GDP per worker in the period 1960–2008 by a novel method based on an information criterion. We find that countries of our sample follow three distinctive growth regimes identified by two deep determinants, namely life expectancy at birth in 1960 and the share of Catholics in 1965, and that each regime is characterized by non-linearities. Growth regimes appear to be the main cause of the increased inequality and polarization, while technological catch-up, proxied by the initial level of GDP per worker, acts in the opposite direction. Finally, human capital marginally reduces polarizat…
Weryfikacja kinetycznego modelu polimeryzacji etylenu wobec metaloorganicznych katalizatorów wanadowych na nośniku magnezowym
1998
The kinetic studies are reviewed on low-pressure polymerization of ethylene over two types of organovanadium catalysts, viz., MgCl 2(THF) 2/VCl 4/Et 2AlCl and MgCl 2(THF) 2VOCl 3Et 2AlCl, each deposited on a magnesium carrier. The polymerization rate was found to be directly related to the catalyst and monomer concentrations (Figs. 2 and 3), unless when the access of the monomer to the reactive V-C bond is restricted by diffusion. Polymer chain termination step was found to result from the reaction of the transfer onto the monomer and to be associated with the regeneration of the active site on which a new macromolecule can be formed. A kinetic model was developed for the ethylene polymeriz…
Linear Types for Higher Order Processes with First Class Directed Channels
1995
Abstract We present a small programming language for distributed systems based on message passing processes. In contrast to similar languages, channels are one-to-one connections between a unique sender and a unique receiver process. Process definitions and channels are first class values and the topology of process systems can change dynamically. The operational semantics of the language is defined by means of graph rewriting rules. A static type system based on the notion of linear types ensures that channels are always used as one-to-one connections.
ES un ASV tirdzniecības attiecību un nākotnes scenāriju analīze
2021
Šī pētījuma mērķis ir uzsvērt ES un ASV tirdzniecības dinamiku un paredzēt tās gaidāmos scenārijus. Metodoloģija ietver teorētisko un empīrisko analīzi. Pārbaudot tirdzniecības ietekmējošos faktorus, tiek sadalītas OLS regresijas no tirdzniecības smaguma modeļa, lai pārbaudītu šādus piecus mainīgos: TTIP sarunu process, IKP uz vienu iedzīvotāju, kopējā zemes platība, FDI un kopīgā valoda. Kopējais novērojums ir 308, aptverot ES-28 un ASV laikposmā no 2009. līdz 2019. gadam. Regresijas rezultāti liecina, ka, izņemot FDI, pārējie četri pārējie mainīgie nav korelēti ar tirdzniecības plūsmu. ES un ASV tirdzniecības prognozes ir noteiktas divos virzienos. Viens no tiem sagaida tirdzniecības plūs…
Proton shape fluctuation and its relation to DIS
2018
We review the recent progress in extracting the proton fluctuating substructure by studying exclusive processes at HERA, and the applications of these developments in the interpretation of the LHC heavy ion data. The possibilities to extract the proton geometry directly from the LHC high-multiplicity proton-nucleus and proton-proton collision data is also discussed. peerReviewed
The development of Early Mathematical Skills – A Theoretical Framework for a Holistic Model
2019
This article presents a theoretical framework for a holistic model of the development of early mathematical skills in early childhood education. The first aim of this study was to conduct a comprehensive international review of the literature to explore early mathematical skills categories. The literature review yielded three early mathematical skills categories, namely (1) numerical skills, (2) spatial thinking skills and (3) mathematical thinking and reasoning skills. Previous studies have shown that several mathematical skills develop gradually and simultaneously in early ages and that these skills areas are interconnected in mathematical skills learning. Accordingly, the second aim of t…
Double role of music criticism : a model of the inner structure of the funding of music
2008
Tarkoituksena on tarkastella, kuinka musiikkikritiikki vaikuttaa musiikin rahoitukseen. Aineistoni muodostuu eri osa-alueiden teksteistä. Tutkimukseni näkökulma perustuu Bourdieu´n, Beckerin ja Maussin määrittelemään kenttään ja sen dynamiikkaan. Kentän asiantuntijaosan muodostavat koulutus, kulttuuripolitiikka, ja muusikko (imagon saajan osana). Kaiken keskiössä on kriitikko, taiteellista tasoa evaluoimassa. Näin muodostuvassa sisäpiirissä voi liikkua päätöksiin vaikuttavaa tietoa. Tämä muodostaa rahoituksen yhden haaran. Toinen haara syntyy lipputuloista. Innovaattoreitta on tutkimusten mukaan 10-15% yleisöstä (, ja sillä saattaa olla sija sisäpiireissäkin), suurin osa yleisöä seuraa inno…
intervenció psicosocial amb victimes de violència de gènere
2012
Cada vegada som més les professionals que treballem amb la temática de la violencia de gènere: treballadores socials, psicòlogues, advocades, educadores...El llibre preten donar unes pautes d'actuació en aquestos casos prioritzant la intervenció integral i sistémica. Les autores parlen des de l'experiència profesional de molts anys
Mobilités étudiantes et territoires universitaires :vers une uniformisation des pratiques ?
2005
Since French Society enters the so-called “Economy of knowledge”, migrations of young people, especially these concerning students, are of most interests. Despite the fact that it could help to understand University as a system and ways regions can evolve, the study of students' migrations was not yet done. A set of results highlights first the main role of French capital region. It shows also main changes in migrations of students following vocational training in University. At least, it reveals that architectures of students' migrations look like these of migrations of the whole French population.
