Promoting self-employment: Does it create more employment and business activity?

2021

International audience; We assess the economic impact of reforms promoting self-employment in the three countries that have implemented such reforms since the early 2000s: the Netherlands, the United Kingdom and France. To that end, we use an unbalanced cross country-industry dataset of 4,226 observations, including 12 OECD countries and 20 market industries, over the 1995-2016 period. We first observe, using country-level data, that the share of self-employed workers in total employment is quite stable or declines over the period in all countries in our dataset, except in the three countries where large reforms promoting self-employment have been implemented, and only after these reforms. …

Pecat amagat és mitg perdonat.... La polèmica entre mossèn Gudiol i Antoni Bulbena a ran de les edicions bibliòfiles de llibres eròtics

2014

Resum: El desembre de 1911 aparegué a la premsa local de Vic un article que va aixecar molta polseguera entre els bibliòfils de tot Catalunya. Un mossèn –historiador de l’art i gran moralista- acusava un conegut editor de llibres de bibliofília –sense dir-ne el nom-, d’editar llibres luxosos de contingut priàpic (pornogràfic). Aquest fet anecdòtic ens serveix per saber qui era l’editor esmentat, què hi havia de cert en l’»acusació» i com va encaixar el vituperat veure’s exposat a la vergonya pública. La correspondència creuada entre els dos protagonistes, exclusivament per mitjà d’un amic comú, ens facilita l’anàlisi de l’argumentari de l’un i de l’altre. Això ens permet copsar com s’enteni…

Materiality and compositorial errors of a poetical incunabulum: the contribution of textual criticism

2019

L’anàlisi material dels testimonis d’una obra literària forma part de la fase de recensio en un procés de crítica textual, que ha d’anar més enllà de la mera descripció del continent. Cal atendre a la informació que donen aquestes característiques quant als continguts, quant al procés de transmissió dels textos, perquè aquestes dades tindran funcionalitat ecdòtica. Així, aquest treball estudia la materialitat i els errors d’un incunable poètic valencià, que és el primer d’una trilogía d’impresos dedicats a la Immaculada Concepció i patrocinats per Ferran Dies. The material analysis of the witnesses of a literary work is part of the phase of recension in a process of textual criticism, which…

Technological differences and convergence in the OECD

2000

Abstract. In this paper we test the homogeneity of the technological parameters among OECD countries, which is the maintained hypothesis in most of the empirical growth literature. We first identify differences in the constant term of the convergence equation estimated for the OECD 1960/1990 sample using a fixed- effects estimator. Then we provide a formal test of the homogeneity of technological parameters across groups of countries. We identify at least two different groups within the OECD, with significantly different technologies. Convergence within each group is fast, supporting the notion of club convergence. Nevertheless, the implausible parameter values obtained for the leading tech…

The regulation of expression of insect cuticle protein genes

2010

International audience; The exoskeleton of insects (cuticle) is an assembly of chitin and cuticle proteins. Its physical properties are determined largely by the proteins it contains, and vary widely with developmental stages and body regions. The genes encoding cuticle proteins are therefore good models to study the molecular mechanisms of signalling by ecdysteroids and juvenile hormones, which regulate molting and metamorphosis in insects. This review summarizes the studies of hormonal regulation of insect cuticle protein genes, and the recent progress in the analysis of the regulatory sequences and transcription factors important for their expression.

Dinotrema cavernicola sp. n. (Hymenoptera, Braconidae, Alysiinae), a new species of the genus Dinotrema Foerster from caves of Spain

2014

Dinotrema cavernicola sp. n. was collected in two caves in Spain. This is the first Dinotrema species known to occur in caves. This new species is described and compared to D. affine (Fischer, 1973) and D. collybiae Munk & Peris-Felipo, 2014, species sharing a mid-longitudinal carina on the propodeum.

Ligands and receptors: common theme in insect storage protein transport.

1999

The passage of macromolecules through biological membranes is an essential process for all multicellular organisms. Insects have developed a mechanism different from that known for all other eukaryotes investigated so far. This review discusses the function and evolution of this mechanism. Insect pupae do not feed during metamorphosis. Therefore they depend on material that has been accumulated during the larval life. At the end of this period, shortly before pupariation, a rise in titer of ecdysteroid hormones induces the incorporation of a large fraction of storage proteins (hexamerins) from the body fluid into the fat body cells. The transport of hexamerins across the cell-membrane is me…

Unemployment Determinants for Women in Spain

2000

Spain has one of the highest rates of unemployment among OECD countries. Some explanations for this stress the importance of unemployment duration compared with entry rates to the unemployment pool. Long-term unemployment rates are particularly high among women in Spain. The object of this paper is to investigate the determinants of unemployment duration among women. It will consider personal characteristics (education and age), family background, socio-economic variables (the number of household earners and household income) and the effect of unemployment benefits, using data from the Household Expenditure Survey 1990-91.
