Selection of suitable housekeeping genes for expression analysis in glioblastoma using quantitative RT-PCR
2009
Abstract Background Considering the broad variation in the expression of housekeeping genes among tissues and experimental situations, studies using quantitative RT-PCR require strict definition of adequate endogenous controls. For glioblastoma, the most common type of tumor in the central nervous system, there was no previous report regarding this issue. Results Here we show that amongst seven frequently used housekeeping genes TBP and HPRT1 are adequate references for glioblastoma gene expression analysis. Evaluation of the expression levels of 12 target genes utilizing different endogenous controls revealed that the normalization method applied might introduce errors in the estimation of…
Cultural adaptation of the Smiling is Fun program for the treatment of depression in the Ecuadorian public health care system: A study protocol for a…
2021
Background Depression is one of the world's major health problems. Due to its high prevalence, it constitutes the first cause of disability among the Americas, where only a very low percentage of the population receives the adequate evidence-based psychological treatment. Internet-Based Interventions (IBIs) are a great alternative to reduce the treatment gap for mental disorders. Although there are several studies in low-and middle-income countries proving IBIs' feasibility and acceptability, there is still little evidence of the effectiveness in diverse social and cultural contexts such as Latin America. Methods Two studies will be described: Study 1 is focused on the cultural adaptation o…
Quantitative colorimetric-imaging analysis of nickel in iron meteorites.
2011
A quantitative analytical imaging approach for determining the nickel content of metallic meteorites is proposed. The approach uses a digital image of a series of standard solutions of the nickel-dimethylglyoxime coloured chelate and a meteorite sample solution subjected to the same treatment as the nickel standards for quantitation. The image is processed with suitable software to assign a colour-dependent numerical value (analytical signal) to each standard. Such a value is directly proportional to the analyte concentration, which facilitates construction of a calibration graph where the value for the unknown sample can be interpolated to calculate the nickel content of the meteorite. The…
IS Security Policy Violations
2012
Employee violations of IS security policies are reported as a key concern for organizations. Although behavioral research on IS security has received increasing attention from IS scholars, little empirical research has examined this problem. To address this research gap, the authors test a model based on Rational Choice Theory RCT-a prominent criminological theory not yet applied in IS-which explains, in terms of a utilitarian calculation, an individual's decision to commit a violation. Empirical results show that the effects of informal sanctions, moral beliefs, and perceived benefits convincingly explain employee IS security policy violations, while the effect of formal sanctions is insig…

Instituciones e intereses en conflicto ante la regulación contable internacional: el caso del sector financiero español
2014
ResumenEl trabajo analiza las interrelaciones entre las normas contables y la información financiera que elaboran las empresas y las instituciones y los incentivos empresariales a fin de contribuir al debate sobre el futuro de las Normas Internacionales de Información Financiera (NIIF). Se destaca que las diferencias en las instituciones —y en concreto en el control de la aplicación de las normas— hacen muy difícil la comparabilidad de la información, lo que impide lograr todas las ventajas que podría conllevar la adopción de las NIIF. Se ilustra esta problemática a través del proceso que sigue la normativa contable española para el sector financiero, proceso en el que el Banco de España de…

How Did I Become a Good Teacher? Implications for Teacher Education
2017
Abstract The professional standards for teachers provide the competences needed for this occupation, in function of the level of education and of the career stages. This study aims to discover the most important training factors which contribute to the acquisition of teacher competences and to establish the implications for teacher education. We have used a mixed-method design as the procedure for collecting, analyzing, and combining both quantitative and qualitative data. To detect the main agents in the teacher competences’ achievement, we applied a questionnaire and we asked the personal opinion of the teachers regarding their evolution in the career. The findings indicated that the prin…
Comparing Cybersecurity Information Exchange Models and Standards for the Common Secure Information Management Framework
2021
Cyber threats have increased in spite of formal economic integration in the world. Decision-makers and authorities need to respond to the growing challenge of cyberthreats by increasing cooperation. Information is one of the main facilities when the objective is to prevent hybrid threats at the EU level and between the western countries. The main purpose of the study is to find out separating and combining factors concerning existing cyber information sharing models and information management frameworks in western countries. The aim is also to find out crucial factors, which affect the utilization of a common Early Warning System for the ECHO stakeholders. The main findings are that unclear…
A practical framework for data management processes and their evaluation in population-based medical registries.
2013
We present a framework for data management processes in population-based medical registries. Existing guidelines lack the concreteness we deem necessary for them to be of practical use, especially concerning the establishment of new registries. Therefore, we propose adjustments and concretisations with regard to data quality, data privacy, data security and registry purposes.First, we separately elaborate on the issues to be included into the framework and present proposals for their improvements. Thereafter, we provide a framework for medical registries based on quasi-standard-operation procedures.The main result is a concise and scientifically based framework that tries to be both broad a…
