, 2009 La preocupación con las medidas de los rasgos psicológicos es antigua y muchos estudios y propuestas de métodos fueron desarrollados para lograr este objetivo. Entre estas propuestas de trabajo se incluye la Teoría de la Respuesta al Ítem (TRI) que, en principio, vino a completar las limitaciones de la Teoría Clásica de los Tests, ampliamente utilizada

Doing less but getting more: Improving forced-choice measures with Item Response Theory [PDF]
, 2010 Forced-choice tests, despite being resistant to response biases and showing good operational validities, have psychometric problems if scored traditionally. These questionnaires are generally longer than their normative counterparts, and more cognitively

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes
FEBS Letters, EarlyView.Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Detecting Crossing Differential Item Functioning (Cdif): Based on Item Response Theory [PDF]
, 2011 The objective of this study was to find out the empirical data of the index of crossing Differential Item Functioning (DIF) and the difference of sensitivity among methods in detecting crossing DIF according to the Item Response Theory.

Don't Tie Yourself to an Onion: Don’t Tie Yourself to Assumptions of Normality [PDF]
, 2012 A structural measurement model (Adams, Wilson, & Wu, 1997) consists of an item response theory model for responses conditional on ability and a structural model that describes the distribution of ability in the population.

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
