Evaluating accuracy and bias of different comparative judgment equating methods against traditional statistical equating

Frontiers in Education
Traditional common-item or common-person statistical equating cannot always be used for standard maintaining or linking between test forms. In some contexts, comparative judgment (CJ) methods which capture expert judgment of quality of student work on ...

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Partial FAK suppression promotes tumor growth, an effect reversed by macrophage p110δ PI3K inactivation

Molecular Oncology, EarlyView.
Partial inhibition of focal adhesion kinase (FAK) can paradoxically promote tumor growth, rather than simply producing a weaker antitumor effect than that observed with strong FAK suppression. In breast cancer and melanoma models, targeting p110δ PI3K, particularly in macrophages, counteracted these tumor‐promoting effects, highlighting the importance ...

Applying Test Equating methods using R

, 2018
The aim of test equating is to adjust the test scores on different test forms so that they can be comparable and used interchangeably. Equating has a central role in large testing programs and it constitutes an important step in the process of collecting,

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

Molecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

A Comparative Evaluation of Kernel Equating and Test Characteristic Curve Equating

, 2017
This study compares the kernel equating (KE) and test characteristic curve (TCC) equating methods using the nonequivalent anchor test equating design. In this Monte Carlo study, four independent variables were examined: sample size, test length, average

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

Molecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

Igualación Lineal de Tres Versiones del Examen de Habilidades y Conocimientos Básicos (EXHCOBA)

Revista Iberoamericana de Evaluación Educativa, 2016
El método estadístico de igualación lineal implica cambiar la escala de manera que se modifique la media y la desviación estándar, mientras se conserva exactamente la forma de la distribución y, en consecuencia las posiciones relativas de los individuos ...

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Ensuring Test Quality over Time by Monitoring the Equating Transformations

, 2017
One important part of ensuring test quality over consecutive test administrations is to make sure that the equating procedure works as intended, especially when the composition of the test taker groups might change over the administrations.
