Ultrastructural changes of the oenocytes of Gryllus bimaculatus DEG (Saltatoria, Insecta) during the moulting cycle
1974
1. The oenocytes of Gryllus bimaculatus are characterized by an abundant smooth-surfaced ER (ATER). In spite of the great cell size the plasma membrane never shows extensive infoldings during the moulting cycle. In addition to mitochondria there are very large numbers of microbodies containing peroxidase but apparently not uricase. Within the second part of the instar the microbodies lie along the clefts which run through the whole cell. 2. The following changes are observed in the course of a moulting cycle: Immediately after hatching the ATER is scarcely developed, some liposomes are located within areas of ATER disappearing some hours later. 20 hours after emergence glycogen deposits app…
Smithian Growth and Complexity
2016
In this paper we argue that Adam Smith’s theory of division and labor and economic growth, in particular through the developments of Alfred Marshall, Allyn Young and Nicholas Kaldor, has characteristics that allow to classify it in the realm of complexity economics. We support this claim by a historical reconstruction of the Smithian growth theory highlighting the characteristics that we show also characterize complex systems. We compare this perspective with the one developed by the traditional economic approach, rooted in general equilibrium, and describe a simple alternative model
Role of NGOs in the implementation of active labour market policies
2012
PurposeThis is a mixed method comparative case study. The aim of this paper is to find the role played by non‐governmental organizations (NGOs) in the implementation of the active labour market policies (ALMPs) of Finland and Sweden, and also the relationship that the NGOs have with the government of the two countries.Design/methodology/approachTwo NGOs were selected in Finland and one NGO was selected in Sweden for the data collection. The two selected NGOs in Finland were Jyväskylän Katulähetys in the City of Jyväskylä and Pirkanmaan Sininauha in the City of Tampere. Meanwhile, the one selected NGO in Sweden was Stockholms Stadsmission in the City of Stockholm. Primary data were collected…
Choices and Enrollments in French Secondary and Higher Education: Repercussions for Second-Generation Immigrants
2013
En ligne sur http://www.jstor.org/discover/10.1086/670729?uid=16804784&uid=3738016&uid=2129&uid=2134&uid=2&uid=70&uid=3&uid=67&uid=16735408&uid=62&uid=5909928&sid=21102655856551; International audience; In France, the proportion of second-generation immigrants enrolling in tertiary education has increased as education has undergone a process of "democratization." This article analyzes their postsecondary choices, access to tertiary programs, dropout, and transition to the labor market, compared to those of students of French origin. Youths of Portuguese origin are more likely to enter vocational higher programs concordant with their preferences and have better chances of completing a tertia…
Aspetti economici e commerciali dell'arancia di Ribera
2010
The Sicily is the first region for orange cultivation in Italy. This sector, throughout the ages, has been characterized by a decrease of the invested areas and by a reduction of the fresh product’s demand; in the meantime, the competitiveness of the new producer countries is increased for a better commercial organization and for lower production costs. The aim of the paper is to improve the knowledge of orange cultivation in Ribera area, in the province of Agrigento (Sicily). It is carried out a microeconomic analysis on a sample of 20 farms to determine profitability of orange cultivation by means of various economic indicators (production costs, profits, net incomes). The business survey…
Urban segregation and unemployment: A case study of the urban area of Marseille – Aix-en-Provence (France)
2018
International audience; In this paper, we study the effects of the spatial organization of the urban area of Marseille – Aix-en-Provence on unemployment there. More specifically, differences in the characteristics of the residential population induce urban stratification with the result that urban structure may affect the probability of employment. In order to evaluate the effects of spatial structure on unemployment, we implement a spatial probit model to reveal the employment probabilities of young adults still living with their parents. Our results support the hypothesis that living in or near a deprived neighborhood decreases the probability of employment.
Urban Smartness: Perspectives Arising in the Periphéria Project
2012
The paper discusses the concept of “urban smartness” starting from the early results of the Peripheria Project. Peripheria is a 30-month pilot B action funded by the European Commission under the CIP ICT PSP Programme and it aims at deploying convergent Future Internet platforms and services for the promotion of sustainable lifestyles in and across emergent networks of “smart” peripheral cities in Europe. Peripheria develops the Living Lab premise of shifting technology R&D out of the laboratory and into the real world in a systemic blend of technological with social innovation. It defines five archetypical “Arenas”—specific urban settings or innovation playgrounds, with defined social feat…
Does one size fit all? The impact of cognitive skills on economic growth
2016
Les Documents de Travail de l'IREDU, n°2016-1; This paper tests for heterogeneous effects of cognitive skills on economic growth across countries. Using a new extended dataset on cognitive skills and controlling for potential endogeneity, we find that the magnitude of the effect is about 60 per cent higher for low-income countries compared to high-income countries, and it more than doubles when low TFP countries are compared to high TFP countries. There are also marked differences across geographic regions. Using data on the share of the population with advanced and minimum skill levels, our results also indicate that high-income countries should focus on increasing the number of high skill…
Technological change and wage premiums amongst high-skilled labour
2019
This study examines the impact of the steam engine, which produced wide and long-lasting economic growth from the 19th century to the early 20th century, on the wages of high-skilled seamen in the Swedish merchant maritime shipping industry. The analysis focuses on the years 1869–1914, which was a transition period during which traditional sailing ships were replaced by steam-powered vessels. The study shows that all high-skilled occupations received wage gains under steam technology. The evidence on wage polarization amongst the high-skill occupations remains subtle, although there is certain evidence that wage premiums vary by occupation. peerReviewed
Technology and Labor Regulations: Theory and Evidence
2015
This paper shows that different labor market policies can lead to differences in technology across sectors in a model of labor saving technologies. Labor market regulations reduce the skill premium and as a result, if technologies are labor saving, countries with more stringent labor regulation, which bind more for low skilled workers, become less technolog- ically advanced in their high skill sectors, but more technologically advanced in their low skill sectors. We then present data on capital-output ratios, on estimated productivity levels and on patent creation, which tend to support the predictions of our model.
