Sidney Armor Reeve: Engineer, Inventor, Progressive, and Underappreciated Utopian
2022
Sidney Armor Reeve, professional engineer and amateur historian, economist, and sociologist, writing during what has been described as the Progressive Era, at-tacked the very foundations of the existing economic and social orders. He explic-itly criticized the dominant commercialism of the capitalist society as being a can-cer, a major cause of inequality and unemployment, offering instead a program of reform that, while some reviewers characterized it as consistent with the program of the socialists, presented something of an alternative vision, one recognizing the primacy of the Ultimate Consumer. His remedy, favoring as it did the central con-trol of the economy, shared at least commonal…
Changing returns to education in Spain during the 1980s
1998
We present evidence on returns to education for Spanish employees during the 1980s, a period of remarkable structural transformations. The results show a declining payoff to education between 1981 and 1991 for lower and intermediate educational levels, whereas higher education does not show a reduction in its return. At the same time, earnings inequality by gender declined noticeably as educational attainment expanded. [JEL I21, J31]
Convergence in OECD countries: technical change, efficiency and productivity
1998
The aim of this study is to analyze labor productivity convergence in the countries of the OECD over the period 1965-90. A non-parametric frontier approach is used to calculate the Malmquist productivity index. By breaking it down, the contribution to the growth of labor productivity of technical progress, of changes in efficiency, and of the accumulation of inputs per worker are quantified. Unlike other studies, the results obtained show that technical change has worked against labor productivity convergence, since it has always been greater in the countries with higher labor productivity. El trabajo tiene como objetivo básico analizar la contribución de las distintas fuentes del crecimien…
Social progress around the world: trends and convergence
2022
Abstract This paper assesses social progress in 139 countries over the period 1995–2017 following the framework proposed by the Social Progress Imperative; a notable contribution is a composite index allowing for comparisons across countries and over time. The index considers 45 raw indicators covering three fundamental pillars of social progress: basic human needs, foundations of well-being, and opportunities. The results point to a marked improvement in social progress all over the world from the mid-1990s, although they also depict a highly polarized world. Cross-country convergence patterns are also investigated, revealing a reduction in the differences in social progress, largely drive…
The environmental Kuznets curve within European countries and sectors: greenhouse emission, production function and technology
2018
Based on the environmental Kuznets curve (EKC) hypothesis and the technological change and the environment literature, our original contribution consists in analysing within the decomposition model the direct and indirect influence of technological change as well as the energy mix on CO2 emissions. Focusing on the dirtiest sectors of 25 EU countries in the period 1997-2005 and considering the endogeneity issue, we estimate an adjusted EKC relationship comparing a single equation model (univariate model) with a simultaneous equations system (bivariate model). Following Lopez (J Environ Econ Manag 27:163-184, 1994), a second equation is introduced where per capita income is a positive functio…
Assessing environmental performance trends in the transport industry: Eco-innovation or catching-up?
2015
Abstract This paper analyses the change in environmental performance that took place in the transport industry of 38 countries between the years 1995 and 2009. Data Envelopment Analysis techniques and directional distance functions are employed to compute Luenberger productivity indicators for the change in environmental performance and its determinants, namely, environmental technical change resulting from eco-innovation and catching-up with best available environmental technologies. Eight air pollutants account for the environmental contaminants from transport activities, and these are aggregated into three main categories of environmental pressures, namely, global warming, tropospheric o…
El trastorn de dèficit d'atenció amb hiperactivitat (TDAH) en població infantil i juvenil
2012
Fruit de la dedicació professional de les autores i enfront d'un problema no sols no resolt, sinó que es considera que està insuficientment abordat, el trastorn de dèficit d'atenció amb hiperactivitat (TDAH) en població infantil i juvenil, es planteja primerament una revisió de la bibliografia, seguida d'un recull de dades sobre la situació actual (amb abundància d'informació procedent dels Estats Units) i d'algunes consideracions i propostes per a posar en marxa les intervencions al nostre àmbit de referència, com ara l'educació que han de rebre, les concepcions morals, els hàbits, etc. Perquè avui dia els infants estan exposats a nombroses influències que han desencadenat que es disparen …
Pre- and postsynaptic type-1 cannabinoid receptors control the alterations of glutamate transmission in experimental autoimmune encephalomyelitis
2013
Type-1 cannabinoid receptors (CB1R) are important regulators of the neurodegenerative damage in multiple sclerosis (MS) and in experimental autoimmune encephalomyelitis (EAE). In GABAergic striatal neurons, CB1R stimulation exerts protective effects by limiting inflammation-induced potentiation of glutamate-mediated spontaneous excitatory postsynaptic currents (sEPSCs). Here we show that CB1R located on GABAergic or on glutamatergic neurons are differentially involved in the pre- and postsynaptic alterations of sEPSCs caused by EAE in the striatum. After induction of EAE, mice selectively lacking CB1R on GABAergic neurons (GABA-CB1R-KO) showed exacerbated alterations of sEPSC duration in GA…
Role of the protein C receptor in cancer progression
2014
The hemostatic system plays pleiotropic roles in cancer progression by shaping the tumor microenvironment and metastatic niches through thrombin-dependent fibrin deposition and platelet activation. Expanding experimental evidence implicates coagulation protease receptors expressed by tumor cells as additional players that directly influence tumor biology. Pro-angiogenic G protein-coupled signaling of TF through protease activated receptor 2 and regulation of tumor cell and vascular integrins through ligation by alternative spliced TF are established pathways driving tumor progression. Our recent work shows that the endothelial protein C receptor (EPCR), a stem cell marker in hematopoietic, …
Failure by corrosion in PC bridges: A case history of a viaduct in Italy
2016
Purpose The paper illustrates a viaduct collapse due to corrosion phenomena. Moreover, a contribution to the issues related to both the control of existing structures and design methods to be followed for the construction of new buildings is provided. Design/methodology/approach The objectives were achieved by in situ observations and numerical analyses. The effects of corrosion phenomena are investigated, and the progressive collapse analysis is provided to be helpful in this case. Findings The damages induced by corrosion phenomena have caused the collapse of the viaduct taken in to account. The performed numerical analyses were able to reproduce the effects of corrosion in terms of redu…
