Essays on the Performance, Subsidization and Internationalization of Social Enterprises

2020

Social enterprises are hybrid organizations that tackle societal challenges by using conventional business models. Being hybrid organizations means that social enterprises pursue dual objectives: social (developmental) and financial. By taking performance, subsidization and internationalization perspectives, this thesis contributes to understanding the hybridity of social enterprises and how this hybridity drives their general operations and key decisions such as foreign market selection and targeting strategy.

Household Debt and Fiscal Multipliers

2015

We study the size of government spending multipliers in a general equilibrium model with search and matching frictions in which we allow for different levels of household indebtedness. The main results of the paper are: (a) the presence of impatient households and private debt helps generate government spending multipliers greater than 1; (b) as financial conditions worsen and impatient consumers find it more difficult to borrow (i.e. in a credit crunch), the size of the government spending multiplier falls; (c) conversely, employment, vacancies and unemployment multipliers are larger when access to credit becomes more difficult; and (d) the model explains the observed pattern of responses …

Instruments, rules, and household debt: the effects of fiscal policy

2015

In this paper, we look at the interplay between the level of household leverage in the economy and fiscal policy, the latter characterised by different combinations of instruments and rules. When the fiscal rule is defined on lump-sum transfers, government spending or consumption taxes, the impact multipliers of transitory fiscal shocks become substantially amplified in an environment of easy access to credit by impatient consumers, regardless of the primary instruments used. However, when the government reacts to debt deviations by raising distortionary taxes on income, labour or capital, the effects of household debt on the size of the impact output multipliers vanish or even reverse, no …

Spanish Abstract: Un breve analisis sobre cuestiones relacionadas a las deudas contraidas por las naciones durante los gobiernos de facto. English Abstract: Should a State pay the debts contracted by a de facto Government? This is an essay that explores the world of the odious debts, trying to find the answers to the most recurrent questions that arise when the third world countries face the time to pay.

H$^{-}$ extraction systems for CERN’s Linac4 H$^{-}$ ion source

2018

Linac4 is a 160 MeV linear H accelerator at CERN. It is an essential part of the beam luminosity upgrade of the Large Hadron Collider (LHC) and will be the primary injector into the chain of circular accelerators. It aims at increasing the beam brightness by a factor of 2, when compared to the currently used 50 MeV linear proton accelerator, Linac2. Linac4’s ion source is a cesiated RF-plasma H ion source. Several beam extraction systems were designed for H beams of 45 keV energy, 50 mA intensity and an electron to H ratio smaller than 5. The goal was to extract a beam with an rms-emittance of mm mrad. One of the main challenges in designing an H extraction system is dumping of the co-extra…

Safety and Immunogenicity of a Vero Cell Culture-Derived Whole-Virus Influenza A(H5N1) Vaccine in a Pediatric Population

2013

BACKGROUND: Children are highly vulnerable to infection with novel influenza viruses. It is essential to develop candidate pandemic influenza vaccines that are safe and effective in the pediatric population. METHODS: Infants and children aged 6-35 months and 3-8 years, respectively, were randomized to receive 2 immunizations with a 7.5-µg or 3.75-µg hemagglutinin (HA) dose of a nonadjuvanted whole-virus A/Vietnam(H5N1) vaccine; adolescents aged 9-17 years received a 7.5-µg dose only. A subset of participants received a booster immunization with an A/Indonesia(H5N1) vaccine approximately 1 year later. HA and neuraminidase antibody responses were assessed. RESULTS: Vaccination was safe and we…

HAWC J2227+610 and its association with G106.3+2.7, a new potential Galactic PeVatron

2020

We present the detection of VHE gamma-ray emission above 100 TeV from HAWC J2227+610 with the HAWC observatory. Combining our observations with previously published results by VERITAS, we interpret the gamma-ray emission from HAWC J2227+610 as emission from protons with a lower limit in their cutoff energy of 800 TeV. The most likely source of the protons is the associated supernova remnant G106.3+2.7, making it a good candidate for a Galactic PeVatron. However, a purely leptonic origin of the observed emission cannot be excluded at this time.

Precision medicine in breast cancer: reality or utopia?

2017

International audience; Many cancers, including breast cancer, have demonstrated prognosis and support advantages thanks to the discovery of targeted therapies. The advent of these new approaches marked the rise of precision medicine, which leads to improve the diagnosis, prognosis and treatment of cancer. Precision medicine takes into account the molecular and biological specificities of the patient and their tumors that will influence the treatment determined by physicians. This new era of medicine is accessible through molecular genetics platforms, the development of high-speed sequencers and means of analysis of these data. Despite the spectacular results in the treatment of cancers inc…
