Diagnosis of human immunodeficiency virus (HIV) infection: multicenter evaluation of a newly developed anti-HIV 1 and 2 enzyme immunoassay.
1994
A new anti-human immunodeficiency virus type 1 and 2 (anti-HIV 1 and 2) test is described. It uses recombinant p24 and peptides covering gp32, gp41, and gp120 to identify HIV-1 and HIV-2 infections. This test has been shown to be specific (99.5%) and sensitive (99.8%). In this respect, the assay was equal or superior to anti-HIV 1 and 2 tests run as references. The test was able to discriminate sera from patients with HIV infections from those from uninfected individuals with excellence; it also exerted high intra- and interassay precisions. The "modular" concept of the test allows the use of single components (gp32 or gp41) to separate between HIV-2 and HIV-1 infections, respectively.
Compensation Options in Joint Ventures. A Real Options Approach
2007
This research focuses on a cluster of dynamic reallocation and restatement of ownership clauses contained in joint venture agreements. These clauses, with potentially significant financial implications, govern the transfer of rights between the parties on two key financial issues: the allocation of profits and losses and the ownership interests in the joint venture. The central contribution of this research is to consider these clauses themselves as non-standard real options and to propose a methodology for assessing their values. Determination of such values will be essential throughout the joint venture negotiation process. In addition, we provide valuable information on another key quest…
Impact of Risk Aversion on Bidder's Optimal Strategy in Takeover Contests
2008
We consider a takeover setting in which bidders are risk averse and study aversion's consequences on their strategy. We found that when bidders are risk averse, under some conditions, their overbidding depends on the size of toeholds they hold. We show that there is a threshold under that a bidder doesn't overbid into the takeover process and becomes aggressive above that treshold. However, if the overbidding increases in toeholds size, it decreases in valuation. Without toeholds, takeovers's results are similar if bidders are averse or neutral risk.
The migrant crisis in the Mediterranean Sea: Empirical evidence on policy interventions
2021
Abstract This paper presents a novel set of empirical evidence to explore several hypotheses regarding the migrant crisis in the Mediterranean Sea. The political instability in transit countries, such as Libya, that made pre-existent repatriation policies ineffective, called for several search-and-rescue operations in the Mediterranean, which in turn have been wrongly accused of fostering illegal immigration and increasing deaths at sea. The empirical results show that the main determinants of the departures are several root causes at the departing African countries, underlining the importance of fighting human smuggling networks. The paper suggests a change in migration studies’ perspectiv…
Nutritional Profiling and the Value of Processing By-Products from Gilthead Sea Bream (
2019
Fish processing industries generate a large volume of discards. In order to fulfil with the principles of a sustainable circular economy, it is necessary to maintain aquaculture by-products in the food chain through the production of high-value biomolecules that can be used as novel ingredients. In this study, we try to give value to the gilthead sea bream by-products, evaluating the composition and the nutritional value of the muscle and six discards commonly obtained from the fish processing industry (fishbone, gills, guts, heads, liver, and skin), which represent ≈ 61% of the whole fish. Significant differences were detected among muscle and by-products for fatty acid and amino acid prof…
Impacto económico de las rentas mínimas: la Renta Valenciana de Inclusión
2019
Las Comunidades Autónomas son las principales responsables de la política de asistencia social en España. Recientemente, la Comunidad Valenciana ha reformado su sistema de rentas mínimas, instaurando la denominada Renta Valenciana de Inclusión. En el presente trabajo se calcula el impacto económico de este programa partiendo de una estimación ex-ante del gasto público a realizar. La estimación cuantifica el número de beneficiarios y el coste presupuestario de la medida; y compara estos resultados con las restantes Comunidades Autónomas. La Comunidad Valenciana se situaría entre las regiones españolas con mayor tasa de cobertura y con mayor gasto por habitante en este tipo de políticas. En b…

Single-tube nested quantitative PCR: a rational and sensitive technique for detection of retroviral DNA. Application to RERV-H/HRV-5 and confirmation…
2003
It was reported earlier that a few patients suffering from non-Hodgkin's lymphoma had low amounts of DNA from the so-called fifth human exogenous retrovirus, HRV-5. A sensitive and rational method for large-scale screening for HRV-5 DNA was therefore developed. It is a single-tube nested quantitative PCR (stnQPCR), which uses two functionally isolated primer pairs and one probe target distinct from related endogenous retroviral sequences, yet encompassing known HRV-5 variation, allowing optimal use of sequence conservation. DNA from lymphoma, myeloma, and follicular dendritic cell lines was tested for HRV-5 positivity, as was DNA from whole blood of blood donors, non-Hodgkin's lymphoma and …
Economic evaluations of ergonomic interventions preventing work-related musculoskeletal disorders: a systematic review of organizational-level interv…
2017
Background Work-related musculoskeletal disorders (WMSD) represent a major public health problem and economic burden to employers, workers and health insurance systems. This systematic review had two objectives: (1) to analyze the cost-benefit results of organizational-level ergonomic workplace-based interventions aimed at preventing WMSD, (2) to explore factors related to the implementation process of these interventions (obstacles and facilitating factors) in order to identify whether economic results may be due to a successful or unsuccessful implementation. Methods Systematic review. Studies were searched in eight electronic databases and in reference lists of included studies. Companio…
Effects of different simplified milk recording methods on genetic evaluation with Test-Day animal model
2007
The aims of the present study were to compare estimated breeding values (EBV) for milk yield using different testing schemes with a test-day animal model and to evaluate the effect of different testing schemes on the ranking of top sheep. Alternative recording schemes that use less information than that currently obtained with a monthly test-day schedule were employed to estimate breeding values. A random regression animal mixed model that used a spline function of days in milk was fitted. EBVs obtained with alternative recording schemes showed different degrees of Spearman correlation with EBVs obtained using the monthly recording scheme. These correlations ranged from 0.77 to 0.92. A redu…
