Education mismatch and qualification mismatch: monetary and non-monetary consequences for workers
Using Spanish data from European Union Household Panel Survey corresponding to
2001, we find that the incidence and the consequences, monetary and non-monetary, are
different for the job-worker qualification and education mismatches. In fact, only 36%
of workers have the same type of fit under both criterions of classification. Additionally,
the qualification mismatches have worse consequences for workers than education
mismatches. Specifically, the monetary consequences are neutrals for overqualified
workers, but negatives for underqualified workers, while the wage of educational
mismatched workers is not significantly different of those who have similar
characteristics and are accurately match in terms of formal education. However, the
overeducated workers earn higher wages than their well-matched co-workers and the
wage penalization for one year of undereducation is lower than the reward for one year
of required education. On the other hand, the analysis of the non-monetary
consequences, by means of job satisfaction, shows that the qualification mismatched
workers have lower probability of being completely satisfied than those who are
accurately match in terms of qualification, while the effects of education mismatch
situations on job satisfaction are no significant. However, among similar jobs, the years
of educational mismatch can have an effect even positive on job satisfaction
Can job/worker mismatches help to explain wages and job satisfaction differences among comparable workers?
The relevance of skill job-worker mismatches is analized along with that of education
mismatch on Spanish data from the European Community Household Panel (ECHP) survey
for the year 2001. Statistical analysis for the prevalence of both types of mismatches, as well
as econometric analysis of their wage and job satisfaction consequences has been carried out.
Three main findings emerge. First, the degree of statistical association between education and
skill mismatches is rather low in the Spanish labour market, suggesting that education mismatch
is a rather poor proxy for skill mismatch. Second, both skill and education mismatches
appear to have separate, negative effects on wages although skill mismatches show stronger
influences. Third, skill mismatches severely reduce workers job satisfaction while the effects
of education mismatch weakened when skill mismatches are accounted for. Consequently,
skill mismatch is found to be a relevant determinant of wage, as well as a stronger predictor of
workers’ utility, than education mismatch

Education and competence mismatches: job satisfaction consequences for workers
The accuracy of the match in the job-worker pairing is analyzed both in terms of education and in
terms of qualification using Spanish data from the 2001 wave of the European Community Household
Panel (ECHP). Regarding the incidence of mismatch situations, the results suggest that the education
match appears to be a rather poor indicator for the qualification match. In addition, ordered discrete
choice models reveal that they have different consequences in terms of job satisfaction as well
Ingeniería de software: evolución curricular
This paper takes a journey through the evolution of teaching software engineering, highlighting the most important aspects in each moment of history, in order to learn the techniques and strategies used in different decades since It was first used the term in 1968, and thus identify the key elements that should be considered in an academic curriculum in areas related to the subject. Through the review of the identified literature on teaching software engineering it was observed that various curricular proposals were made, but it was only until the 2000s when it was possible to unify criteria, publishing the SWEBOK guidance document compiles efforts made to define the body of knowledge. The guide had a recent update to version 3.0 in 2014.Este artículo hace un recorrido por la evolución del currículo de la ingeniería de software, destacando los aspectos de mayor relevancia en cada uno de los momentos de la historia con el fin de conocer las técnicas y estrategias utilizadas en las diferentes décadas, desde que fue utilizado por primera vez el término en 1968, y así identificar los elementos claves que se deberían tener en cuenta en un currículo académico en las áreas relacionadas con esta disciplina. A través de la revisión de la literatura identificada sobre la enseñanza de la ingeniería de software se observó que se realizaron diversas propuestas curriculares, pero fue solo hasta la década del 2000 cuando se unificaron criterios, publicándose la guía SWEBOK, documento que recopila los esfuerzos realizados para definir el cuerpo de conocimiento. La guía tuvo una reciente actualización a la versión 3.0 en el año 2014
Septo-optic dysplasia (Morsier syndrome)
Se presentan dos casos de displasia septoóotica o Síndrome de Morsier, una entidad del sistema nervioso que sólo se puede confirmar por medio de neuroimágenes. Estas consisten en ausencia de septum pellucidum, agenesia de cuerpo calloso, atrofia cerebelosa, porencefalia, dilatación ventricular y lipomas o quistes cerebrales, junto con neurohipófisis ectópica, aplásica o hipoplásica. El cuadro clínico es variable, dependiendo del grado de compro-miso del nervio óptico, la función hipotalamica y las alteraciones asociadas. El pronóstico en general es bueno.

Effect of the temperature and relative humidity in stored sotol (Dasylirion cedrosanum Trel.) seeds on fungi biodiversity
The objective of the research was to identify the fungi in sotol seeds at different conditions of temperature and relative humidity. Seeds were collected at Buñuelos, municipality, and taken to the Laboratory of the Center for Training and Development in Seed Technology (CCDTS) at Universidad Autonoma Agraria Antonio Narro. The seed was stored for a period of 90 days, whit conditions of 60, 75, 80 and 85% of relative humidity kept at 5, 15 and 25 °C. Fungi identifying by morphological criteria. A completely randomized experiment using R software, with factorial arrangement whit two replications. Pathogens identified were: Aspergillus glaucus, Aspergillus niger, Fusarium sp., Penicillium sp., Aspergillus candidus, Cladosporiun sp., Alternaria sp. and Aspergillus chraceus, the results showed that the higher the humidity, temperature and storage time, the incidence of fungi tends to be higher. Fungi with a higher presence in sotol seeds were: Aspergillus glaucus and Penicillium sp. Safe storage environments for sotol seeds reported in this work are 5 °C and a relative humidity of 60-75%. Sotol seeds tolerates conditions of 15 °C and a relative humidity up to 75%. 
Electrode-dependent asymmetric conduction mechanisms in K0.5Na0.5NbO3 micro-capacitors
The ultimate performance of devices employing lead-free piezoelectrics is determined not only by the intrinsic properties of the piezo, but also by processes and materials employed to create the electric contacts. In this paper, we investigate the impact of different metallic electrodes with increasing chemical reactivity (Pt, Ni, Ti, Cr), on the asymmetric behavior of the leakage current in M/K0.5Na0.5NbO3/Pt(111) micro-capacitors, where M stands for the top metallic electrode. For all electrodes we found a marked leakage asymmetry that we ascribed to the presence of a Schottky-like rectifying junction at the M/K0.5Na0.5NbO3/Pt(111) bottom interface, while the corresponding junction at the top interface is deeply affected by the creation of oxygen vacancies due to oxygen scavenging during the growth of the top metallic electrodes, leading to an almost ohmic top contact. The leakage increases with the reactivity of the electrodes, while the asymmetry decreases, thus suggesting that the creation of the top metal/K0.5Na0.5NbO3 interface generates oxygen vacancies diffusing down to the bottom interface and impacting on the rectifying behavior of the Schottky-like junction. Noteworthy, this asymmetric conduction can reflect in an asymmetric piezoelectric and ferroelectric behavior, as a sizable portion of the applied voltage drops across the rectifying junction in reverse bias, thus hampering symmetric bipolar operation, especially in leaky materials
Alzheimer’s Disease Studies in the Tex-Mex Border: Dissecting a Complex Multifactorial Problem
Purpose: Alzheimer’s Disease (ALZ) is the leading cause of dementia in the aging population, and Latinos have \u3e3 times higher risk to develop dementia than the overall US population. Although several studies have examined for possible causes of this increased risk, lack of comprehensive information plus a reduced number of Latino samples available in each study have hindered the answers.
Description: The University of Texas Rio Grande Valley has joined two large studies looking for multiple biomarkers associated with ALZ: The South Texas Alzheimer’s Center Clinical Data Repository and Biobank (STAC) and the Texas Alzheimer’s Research and Care Consortium (TARCC). We are now collecting clinical data along with neuroimaging and lab biomarkers from each individual enrolled in these studies, with the aim to enroll a large majority of Latinos in our site sample, which will help to elucidate the differences and risk factors inherent to our population in the border. We are also analyzing data from different Latin-American studies to study specific genetic risks, environmental factors, and their interactions.
Partners: UTRGV has partnered with UTHSCSA for the STAC study and with many other academic research institutions at TARCC. We aim to provide experiences of clinical training to our psychology students and residents of medical specialties, as well as analysis opportunities and opening postdoctoral positions related to the development of this field at UTRGV.
Looking Ahead: We expect to generate substantial contributions to the knowledge of cognitive decline in underserved populations, which can lead to improved treatments and better clinical care. Postdoctoral positions will be opening soon at the Institute of Neuroscience
