A Framework to Evaluate Software Developer’s Productivity The VALORTIA Project
Currently, there is a lack in companies developing software in relation to assessing their staff’s productivity
before executing software projects, with the aim of improving effectiveness and efficiency. QuEF (Quality
Evaluation Framework) is a framework that allows defining quality management tasks based on a model.
The main purpose of this framework is twofold: improve an entity’s continuous quality, and given a context,
decide between a set of entity’s instances on the most appropriate one. Thus, the aim of this paper is to
make this framework available to evaluate productivity of professionals along software development and
select the most appropriate experts to implement the suggested project. For this goal, Valortia platform,
capable of carrying out this task by following the QuEF framework guidelines, is designed. Valortia is a
platform to certify users' knowledge on a specific area and centralize all certification management in its
model by means of providing protocols and methods for a suitable management, improving efficiency and
effectiveness, reducing cost and ensuring continuous quality.Ministerio de Ciencia e Innovación TIN2013-46928-C3-3-
Olfactory Dysfunction in Patients with Chronic Rhinosinusitis
Objectives. To measure the prevalence of and identify the clinical characteristics associated with olfactory decline in patients with chronic rhinosinusitis. Methods and Materials. There is analytical, prospective, and observational study in adult patients with a diagnosis of chronic rhinosinusitis. The olfactory test used was the Connecticut Chemosensory Clinical Research Center (CCCRC). Results. They are 33 patients total. Within the group of patients aged 18 to 39, 9% had normosmia, 73% hyposmia, and 18% anosmia (P<0.001). Between 40 and 64 years old, there was no patient with normosmia, 63% hyposmia, and 37% anosmia (P<0.001). Of patients older than 65 years old, 33% showed mild hyposmia, 34% severe hyposmia, and 33% anosmia (P<0.001). 52% were females, and 48% were males. Conclusion. Nasal polyposis, asthma, septal deviation, turbinate hypertrophy, tobacco, and allergic rhinitis are predicting factors of olfactory dysfunction. Antecedents of previous endoscopic surgeries, age, and gender would not be associated with olfactory loss

Residual confounding or reverse causation cannot be excluded. Therefore, we estimated the causal association of milk consumption with stroke and CHD risk through instrumental variable (IV) and gene-outcome analyses. IV analysis included 29 328 participants (4611 stroke; 9828 CHD) of the European Prospective Investigation into Cancer and Nutrition (EPIC)-CVD (eight European countries) and European Prospective Investigation into Cancer and Nutrition-Netherlands (EPIC-NL) case-cohort studies. rs4988235, a lactase persistence (LP) SNP which enables digestion of lactose in adulthood was used as genetic instrument. Intake of milk was first regressed on rs4988235 in a linear regression model. Next, associations of genetically predicted milk consumption with stroke and CHD were estimated using Prentice-weighted Cox regression. Gene-outcome analysis included 777 024 participants (50 804 cases) from MEGASTROKE (including EPIC-CVD), UK Biobank and EPIC-NL for stroke, and 483 966 participants (61 612 cases) from CARDIoGRAM, UK Biobank, EPIC-CVD and EPIC-NL for CHD. In IV analyses, each additional LP allele was associated with a higher intake of milk in EPIC-CVD (beta = 13 center dot 7 g/d; 95 % CI 8 center dot 4, 19 center dot 1) and EPIC-NL (36 center dot 8 g/d; 95 % CI 20 center dot 0, 53 center dot 5). Genetically predicted milk intake was not associated with stroke (HR per 25 g/d 1 center dot 05; 95 % CI 0 center dot 94, 1 center dot 16) or CHD (1 center dot 02; 95 % CI 0 center dot 96, 1 center dot 08). In gene-outcome analyses, there was no association of rs4988235 with risk of stroke (OR 1 center dot 02; 95 % CI 0 center dot 99, 1 center dot 05) or CHD (OR 0 center dot 99; 95 % CI 0 center dot 95, 1 center dot 03). Current Mendelian randomisation analysis does not provide evidence for a causal inverse relationship between milk consumption and stroke or CHD risk.Netherlands Heart Foundation 2015T019UK Research & Innovation (UKRI)

Knowledge economy : urban - regional perspectives
El conocimiento y su aplicación en la economía, ha sido siempre un factor importante del desarrollo socio-económico.
El conocimiento toma relevancia en la economía contemporánea al invertirse la jerarquización de los factores del desarrollo, cobrando mayor importancia los factores intangibles, como el conocimiento, el cual se convierte en el recurso fundamental para los procesos productivos. En este contexto, surgieron los estudios relacionados con la Economía Regional del Conocimiento (ERC) así como los estudios relativos al Desarrollo
basado en el Conocimiento (DBC). Ambas perspectivas teóricas han establecido indicadores para explicar el fenómeno de la economía del conocimiento desde su base territorial, sea a nivel regional (ERC) o desde la ciudad (DBC). A manera exploratoria consideramos que los indicadores de los sistemas regionales de innovación pueden complementarse con los indicadores del desarrollo basado en el conocimiento, sobre todo
por la dimensión meta-cultural a la que hacen referencia estos estudios.The knowledge and its application in the economy has always been an important factor for the socioeconomic development.
The knowledge takes relevance in the contemporary economy whenthe ranking of the
development factors is inverted. When it happens, the intangible factors such as knowledge, are crucial for the productive process. In this context, the Regional Knowledge Economy (RKE) and the Knowledge- based Development (KBD) studies came up.
Both RKE and KBD as theoretical perspectives, have stablished indicators to explain the territorial base of knowledge economy in a regional and urban level. The indicators of the regional innovation systems could be complemented with the indicators of the knowledge based development becuase of the metacultural dimension that this studies include.Fil: Marquina Sánchez, María de Lourdes.

Confirmation of symmetrical distributions of clinical attachment loss and tooth loss in a homogeneous Mexican adult male population
Background/purpose
To ascertain whether or not clinical attachment loss and tooth loss are present with similar severity and prevalence across the two sides of the mouth in a homogeneous sample of urban male adults.
Materials and methods
A cross-sectional study was carried out on 161 policemen (a largely homogeneous group in terms of ethnic background, socioeconomic status, sex, occupation, and medical/dental insurance) in Campeche, Mexico. Periodontal examinations were undertaken using the Florida Probe System in a dental chair by one trained and standardized examiner (kappa ≥ 0.60) to determine clinical attachment loss and tooth loss. We examined six sites in all teeth present in the mouth (a maximum of 168 sites, no third molars). Because of correlated data between observations, McNemar (for tooth loss) and Wilcoxon (for attachment loss) signed-rank tests were used to compare right and left sites within the same patient.
Results
The mean age was 38.4 ± 11.0 years. The mean number of teeth present was 24.4 ± 4.6; the mean number of periodontal sites/person was 146.7 ± 27.8. All P values were ≥ 0.05 (except for attachment loss in the upper first premolars), suggesting that there were no statistically significant differences between the right and left sides for the frequency of presentation of these two conditions.
Conclusion
Tooth loss and attachment loss measurements largely resemble each other on both sides of the mouth

Seasonal concentration of nitrates in a loamy silt soil of the Upper Río Negro Valley.
La abundancia y bajo costo del recurso hídrico
en el Alto Valle de Río Negro combinados con un
manejo ineficiente del mismo, principalmente durante
la primera parte de la primavera, época en la que
los productores riegan con mayor frecuencia para
luchar pasivamente contra las probables heladas
tardías, permiten inferir que los nitratos presentes
en el suelo, así como el aportado por los fertilizantes
nitrogenados, están sujetos al lixiviado durante una
gran parte del ciclo productivo. En la actualidad no
existen estudios regionales que ilustren la variación
estacional de la concentración de nitratos en la zona
de exploración radical de frutales, por lo que se
inició el presente trabajo con el propósito de: a)
medir la concentración de los nitratos en el perfil del
suelo cultivado con manzanos, desde el período de
floración hasta el inicio de caída de hojas, con fertilización
nitrogenada en dos dosis y sin fertilización
a distintas profundidades de extracción; b) determinar
la eficiencia del riego a manto de dicho monte.
Se ensayaron dos concentraciones de nitrógeno,
adicionado como nitrato de amonio en dos oportunidades:
el 50% a la caída de los pétalos y el 50%
restante cercano a la cosecha, correspondiendo a
dosis de 100 kg ha-1 (N1), 200 kg ha-1 (N2) y un
testigo sin agregado de N (N0), durante el período
2004-2005 y 2005-2006. Para determinar los niveles
de N en el suelo, expresado como nitratos, se
extrajeron muestras del mismo a tres profundidades
0-30; 30-60; 60-90 cm, al inicio de floración,
antes del primer riego y después de cada riego. La
lámina de agua empleada para el riego a manto
osciló entre 1712 y 2400 mm, con un aprovechamiento
a campo del 30%. La concentración de nitratos
fue baja cuando no se fertilizó, manteniéndose
alrededor de 22 mg kg-1 en superficie y reduciéndose
a la mitad a la profundidad de 30-60 cm, durante
el período de muestreo. En ambas dosis empleadas,
el contenido de nitratos del suelo fue mayor llegando
a 175 y 300 mg kg-1, respectivamente. Estos valores
se igualan a los del testigo a los 30 días en el
caso de N1 y a los 60 días para N2. Los resultados
permiten inferir que la concentración de nitratos fue
efímera en el perfil del suelo y mejoró la eficiencia de
riego, principalmente durante la primavera con el fin
de minimizar pérdidas de nitrógeno.The abundance and the low cost of the
irrigation water in the Upper Río Negro Valley entail
to the inefficient use of the resource, mainly during
the first part of the spring when the growers irrigate
frequently for passive frost control. Such situation
allows us to infer that nitrates derived from either
the soil or the fertilizer is prone to be leached from
the soil profile during most part of the growing
season. Actuality there are no local studies to show
the variation seasonal concentration of soil nitrates
in the rooting zone of the fruit trees, therefore we
initiated a study with the aims of: a) to measure the
concentration of nitrate in the soil profile occupied
with roots from the stage of flowering to the
beginning of leaf fall, with nitrogen fertilization in
two equal doses and without nitrogen, a different
profundity the extraction; b) to determine the
efficiency of irrigation of the orchard irrigated by
flooding. Two concentrations of nitrogen were
experimented, applied as ammonium nitrate in two
opportunities, 50% at petal fall and the rest at
harvest and a control treatment without N (N0),
corresponding a dose the 100 Kg ha-1 (N1) and
200 kg ha-1 (N2), period 2004-2005 and 2005-2006.
Soil samples at three soil depths (0-30, 30-60 and
60-90 cm) were taken in the beginning of flowering
and previous any irrigation and then from October
to April after each irrigation. The concentration of
nitrates along the season remained in 22 mg kg-1 in
the top soil and decreased 50% in the 30-60 cm
soil depth. In N1 and N2 the concentration increased
sharply after the application of the fertilizer and
reached concentrations in the 0-30 cm of 175 mg kg-1
and 300 mg kg-1 in N1 and N2, respectively. However
30 days after the application of N1 and 60 days
after the application of N2 the concentrations of
nitrates were similar to N0. The volume of water
applied per hectare was 1712-2400 mm with a
30% efficiency. The results showed that the effect
of the fertilizer application lasted a short period of
time and the irrigation efficiency should be improved
in order to avoid nitrate leaching.Fil: Aruani, María Cristina.Fil: Sánchez, Enrique E..Fil: Reeb, Pablo.Fil: Aun, Elizabeth
