Análisis de la experiencia del programa jóvenes en acción en Bogotá, como alternativa para romper el círculo de la pobreza a través de la alianza empresa-estado-universidad durante el periodo 2003 a 2007

El problema de la pobreza en el mundo es una constante que tiende a incrementarse y reproducirse viralmente. Latinoamérica particularmente ha logrado avances destacados, sin embargo se necesitan medidas estructurales y transformaciones institucionales para lograr reducir la pobreza, empezando por la base de la pirámide con los jóvenes. Es por tanto que la motivación de este caso de estudio es analizar cómo la alianza entre la academia, el sector privado y el estado pueden ser alternativa para romper el círculo de la pobreza.

Análisis de la marcha del 4 de febrero de 2008 como ejemplo de las nuevas metodologías de movilización social a la luz de la noopolitik.

La Ciencia Política siempre ha buscado profundizar en el fenómeno del poder y sus causas. Las teorías han cambiado conforme a las circunstancias sociales a lo largo de la historia; no obstante, en la actualidad las dinámicas de comunicación facilitadas por elementos tecnológicos han generado coyunturas sin antecedentes como la ocurrida en Colombia el 4 de febrero de 2008 “Un Millón de voces contra las FARC” La generalización en el uso de Internet y –sobre todo- las redes sociales ha producido un acelerado nivel de activismo debido a la facilidad de cooperación y coordinación que se deriva de estructuras en red. Es sano pensar en una reevaluación de la teoría tradicional del poder vertical y traer al campo teórico nuevos elementos que generen herramientas de análisis sobre comunicación, poder horizontal, activismo y oportunidades políticas. El nacimiento de lo que algunos llaman “sociedad informacional” es lo que permitirá describir el concepto de “noopolitik”. Las que otrora eran movilizaciones políticas costosas y exigentes en recursos de coordinación y tiempo han venido siendo reemplazadas por explosiones de activismo catalizadas por un sentimiento común que han sabido servirse de las ventajas tecnológicas para lograr sus objetivos. Bien habla de ello el caso de estudio de esta investigación al ser la movilización más grande registrada, con más de 12 millones de personas alrededor del mundo y con el uso protagónico de redes sociales. El valor de la información –y por supuesto su difusión-, es ahora uno de los principales asuntos de la Ciencia Política moderna.

Dinámicas de externalización entre las ONG locales y las ONG extranjeras (terceros actores) presentes en Egipto: 2004-2009 (TERCEROS ACTORES) PRESENTES EN EGIPTO: 2004-2009

El propósito de la presente monografía es evaluar el papel de las ONG internacionales en la apertura de espacios de participación política para la sociedad civil en Egipto. En ese sentido, se analiza el contexto de oportunidades políticas locales y transnacionales del país, así como los procesos de articulación entre la política local e internacional a través de los niveles de integración entre sus actores. Mediante una investigación de tipo cualitativa basada en los desarrollos sobre teorías de la acción colectiva planteados por Sidney Tarrow, Charles Tilly, Robert Benford y David Snow, y las teorías sobre redes transnacionales de defensa desarrolladas por Margaret Keck y Kathryn Sikkink, se avanza hacia la identificación del desarrollo de procesos de externalización como medio para el fortalecimiento de organizaciones locales como alternativa de oposición política.

Labor's shares - aggregate and industry: accounting for both in a model of unbalanced growth with induced innovation

The relative stability of aggregate labor's share constitutes one of the great macroeconomic ratios. However, relative stability at the aggregate level masks the unbalanced nature of industry labor's shares – the Kuznets stylized facts underlie those of Kaldor. We present a two-sector – one labor-only and the other using both capital and labor – model of unbalanced economic development with induced innovation that can rationalize these phenomena as well as several other empirical regularities of actual economies. Specifically, the model features (i) one sector ("goods" production) becoming increasingly capital-intensive over time; (ii) an increasing relative price and share in total output of the labor-only sector ("services"); and (iii) diverging sectoral labor's shares despite (iii) an aggregate labor's share that converges from above to a value between 0 and unity. Furthermore, the model (iv) supports either a neoclassical steadystate or long-run endogenous growth, giving it the potential to account for a wide range of real world development experiences.

Measuring and testing for the systemically important financial institutions

This paper analyzes the measure of systemic importance ∆CoV aR proposed by Adrian and Brunnermeier (2009, 2010) within the context of a similar class of risk measures used in the risk management literature. In addition, we develop a series of testing procedures, based on ∆CoV aR, to identify and rank the systemically important institutions. We stress the importance of statistical testing in interpreting the measure of systemic importance. An empirical application illustrates the testing procedures, using equity data for three European banks.

A budget for Europe's Monetary Union. Bruegel Policy Contribution 2012/22, December 2012

In a monetary union, national fiscal deficits are of limited help to counteract deep recessions; union-wide support is needed. A common euro-area budget (1) should provide a temporary but significant transfer of resources in case of large regional shocks, (2) would be an instrument to counteract severe recessions in the area as a whole, and (3) would ensure financial stability. The four main options for stabilisation of regional shocks to the euro area are: unemployment insurance, payments related to deviations of output from potential, the narrowing of large spreads, and discretionary spending. The common resource would need to be well-designed to be distributionally neutral, avoid free-riding behaviour and foster structural change while be of sufficient size to have an impact. Linking budget support to large deviations of output from potential appears to be the best option. A borrowing capacity equipped with a structural balanced budget rule could address area-wide shocks. It could serve as the fiscal backstop to the bank resolution authority. Resources amounting to 2 percent of euro-area GDP would be needed for stabilisation policy and financial stability.

Time patterns in UK demand for alcohol and tobacco: an application of the EM algorithm

Capturing the pattern of structural change is a relevant task in applied demand analysis, as consumer preferences may vary significantly over time. Filtering and smoothing techniques have recently played an increasingly relevant role. A dynamic Almost Ideal Demand System with random walk parameters is estimated in order to detect modifications in consumer habits and preferences, as well as changes in the behavioural response to prices and income. Systemwise estimation, consistent with the underlying constraints from economic theory, is achieved through the EM algorithm. The proposed model is applied to UK aggregate consumption of alcohol and tobacco, using quarterly data from 1963 to 2003. Increased alcohol consumption is explained by a preference shift, addictive behaviour and a lower price elasticity. The dynamic and time-varying specification is consistent with the theoretical requirements imposed at each sample point. (c) 2005 Elsevier B.V. All rights reserved.

The adsorbed conformation of globular proteins at the air/water interface

External reflection FTIR spectroscopy and surface pressure measurements were used to compare conformational changes in the adsorbed structures of three globular proteins at the air/water interface. Of the three proteins studied, lysozyme, bovine serum albumin and P-lactoglobulin, lysozyme was unique in its behaviour. Lysozyme adsorption was slow, taking approximately 2.5 h to reach a surface pressure plateau (from a 0.07 mM solution), and led to significant structural change. The FTIR spectra revealed that lysozyme formed a highly networked adsorbed layer of unfolded protein with high antiparallel beta-sheet content and that these changes occurred rapidly (within 10 min). This non-native secondary structure is analogous to that of a 3D heat-set protein gel, suggesting that the adsorbed protein formed a highly networked interfacial layer. Albumin and P-lactoglobulin adsorbed rapidly (reaching a plateau within 10 min) and with little chance to their native secondary structure.

Apparent specific volumes and tastes of cyclamates, other sulfamates, saccharins and acesulfame sweeteners

Measurements of apparent specific volume (ASV) for a series of alternative sweeteners (cyclamates, sulfamates, saccharins, acesulfames and anilinomethanesulfonates) have been made. Taste data have been obtained for many of the new compounds unless the toxicity of the associated metals precluded this. Apparent molar volume (AMV), isentropic specific (IASC) and isentropic molar (IAMC) compressibilities were also measured. Sixteen metallic cyclamates cyc-C6H11NHSO3M and two phenylsulfamates ArNHSO3Na, namely 3.5-dimethyl- and 3,4-dimethoxyphenylsulfamates have been examined. When the ASVs for these are combined with those for 15 aliphatic, aromatic and alicyclic sulfamates from a previous study, many of the values are seen to fall into the region that was previously identified as being the "sweet area", i.e. the ASVs lay between similar to0.5 and similar to0.7 (a few sweet compounds fall below this range and it is suggested that it could be extended slightly to accommodate these). Interestingly, the anilinomethanesulfonates, ArNHCH2SO3Na (Ar = C6H5-, 3-MeC6H4- and 3-ClC6H4-) lie clearly in the sweet region but only one of them shows slight sweetness showing that the molecular structural change made (compared with the 'parent' sulfamate-NHSO3-) cannot be accommodated at the receptor site.

Polymer-mediated disruption of drug crystallinity

Ibuprofen (IB), a BCS Class II compound, is a highly crystalline substance with poor solubility properties. Here we report on the disruption of this crystalline structure upon intimate contact with the polymeric carrier cross-linked polyvinylpyrrolidone (PVP-CL) facilitated by low energy simple mixing. Whilst strong molecular interactions between APIs and carriers within delivery systems would be expected on melting or through solvent depositions, this is not the case with less energetic mixing. Simple mixing of the two compounds resulted in a significant decrease in the differential scanning calorimetry (DSC) melting enthalpy for IB, indicating that approximately 30% of the crystalline content was disordered. This structural change was confirmed by broadening and intensity diminution of characteristic IB X-ray powder diffractometry (PXRD) peaks. Unexpectedly, the crystalline content of the drug continued to decrease upon storage under ambient conditions. The molecular environment of the mixture was further investigated using Fourier transform infrared (FT-IR) and Fourier transform Raman (FT-Raman) spectroscopy. These data suggest that the primary interaction between these components of the physical mix is hydrogen bonding, with a secondary mechanism involving electrostatic/hydrophobic interactions through the IB benzene ring. Such interactions and subsequent loss of crystallinity could confer a dissolution rate advantage for IB. (C) 2006 Elsevier B.V. All rights reserved.

A ferromagnetic methoxido-bridged Mn(III) dimer and a spin-canted metamagnetic μ1,3-azido-bridged chain

Two new Mn(III) complexes of formulas [MnL1(N-3)(OMe)](2) (1) and [MnL2(N-3)(2)](n) (2) have been synthesized by using two tridentate NNO-donor Schiff base ligands HL1{(2-[(3-methylaminoethylimino)-methyl]-phenol)} and HL2 {(2-[1-(2-dimethylaminoethylimino)methyl]-phenol)}, respectively. Substitution of the H atom on the secondary amine group of the N-methyldiamine fragment of the Schiff base by a methyl group leads to a drastic structural change from a methoxido-bridged dimer (1) to a single mu(1,3)-azido-bridged 1D helical polymer (2). Both complexes were characterized by single-crystal X-ray structural analyses and variable-temperature magnetic susceptibility measurements. The magnetic properties of compound I show the presence of weak ferromagnetic exchange interactions mediated by double methoiddo bridges (J = 0.95 cm(-1)). Compound 2 shows the existence of a weak antiferromangetic coupling along the chain (J = -8.5 cm(-1)) through the single mu(1,3)-N-3 bridge with a spin canting that leads to a long-range antiferromagnetic order at T-c approximate to 9.3 K and a canting leading to a weak ferromagnetic long-range order at T-c approximate to 8.5 K. It also exibits metamagnetic behavior at low temperatures with a critical field of ca.1.2 T due to the weak antiferromagnetic interchain interactions that appear in the canted ordered phase.

Can we really trust offshoring indices?

This paper argues that offshoring indices often measure something different than what we think they are. Using data from input-output tables of 21 European countries from 1995 to 2006 we decompose an offshoring index, distinguishing between a domestic (structural change) and an international component (imported inputs ratio). Regarding offshoring of business services, a large share of the index variation is driven by the domestic component. This is even more pronounced for overall service offshoring. In the case of material offshoring, by contrast, the international component drives the main variation of the indices. Our results therefore show that, regarding (business) services, the typical calculation of offshoring indices tends to over estimate the role of the imported inputs component, neglecting the role played by structural changes in the economy.
