Testing with a nuisance parameter present only under the alternative: a score-based approach with application to segmented modelling

2016

ABSTRACTWe introduce a score-type statistic to test for a non-zero regression coefficient when the relevant term involves a nuisance parameter present only under the alternative. Despite the non-regularity and complexity of the problem and unlike the previous approaches, the proposed test statistic does not require the nuisance to be estimated. It is simple to implement by relying on the conventional distributions, such as Normal or t, and it justified in the setting of probabilistic coherence. We focus on testing for the existence of a breakpoint in segmented regression, and illustrate the methodology with an analysis on data of DNA copy number aberrations and gene expression profiles from…

The Strategic Scorecards: An Instrumentation of the Strategic Management Accounting. Exploration of a Concept, Instrumentation and Results from a Fre…

2003

I describe in this study a generic model of strategic management accounting instrumentation: the strategic scorecards. In order to build this generic model, I review in the existing literature the concepts of Strategic Control and Strategic Management Accounting (SMA). I present the characteristics of these concepts and analyse the reasons why they emerged. I show how the strategic scorecards are an instrumentation of the SMA in studying the most widely known and esteemed scorecards: the Balanced Scorecards (Kaplan & Norton, 1996) and Skandia's Navigator (Edvinsson & Malone, 1997). I then clarify the outlines for a generic model of strategic scorecard and disclose an "a priori" typology of …

Genotype influence on shelf life behaviour of minimal processed loquat (Eriobotrya japonica (Thunb.) Lindl.) fruit: the role of sugar, acid organics …

2022

AbstractBackgroundLoquat cultivars cultivated in Southern Italy are very appreciated by consumers for their sensorial characteristics, such as persistent aroma and taste. Apposite maturity indexes for peeling and processing loquat fruit were investigated to increase diffusion of minimally processed loquat. The genotype’s effect on the minimally processed loquat fruit shelf life and quality harvested at commercial maturity (80% yellow color) was investigated on peeled fruit stored at 5 °C for 10 days. The role of sugars, organic acids and phenols composition was observed through in depth qualitative analysis. In addition, several qualitative analyses were carried out to determine the quality…

Toward Effective Risk Management in is Development: Introduction to Risk Based Scorecard

1999

Though, both academics and practitioners, recognise the importance of risks related to information systems development (ISD) process, relatively little attention has been paid to this problem. In this paper we distinguish three types of ISD activity, representing three levels of IT concerns: the development of an organization’s IT strategy (the strategy level); the selection of a portfolio of IS projects (the planning level); the management of a system development (the management level); a useful feature of the book: the exercises

Aplicabilidad de un Score de TCAR para determinar la gravedad y el pronóstico en el momento del diagnóstico de la fibrosis pulmonar idiopática.

2016

Introducción: La TCAR es una exploración de primer orden en el diagnóstico y seguimiento de la fibrosis pulmonar idiopática (FPI), sin embargo no se utiliza para ponderar la gravedad. Bajo la hipótesis de que cuantificar la extensión de FPI en TCAR sería muy útil para establecer la gravedad al diagnóstico y monitorizar su evolución, nos propusimos evaluar la utilidad de un score semicuantitativo de FPI en TCAR en relación con parámetros funcionales habitualmente empleados para establecer la gravedad y monitorizar la evolución del proceso fibrótico. Pacientes y Método: Estudio prospectivo incluyendo 48 pacientes consecutivos diagnosticados de FPI. Mediante un score semicuantitativo se puntuó…

Polymorphism of the transcription factor 7-like 2 gene (TCF7L2) interacts with obesity on type-2 diabetes in the PREDIMED study emphasizing the heter…

2016

Nutrigenetic studies analyzing gene–diet interactions of the TCF7L2-rs7903146 C > T polymorphism on type-2 diabetes (T2D) have shown controversial results. A reason contributing to this may be the additional modulation by obesity. Moreover, TCF7L2-rs7903146 is one of the most influential variants in T2D-genetic risk scores (GRS). Therefore, to increase the predictive value (PV) of GRS it is necessary to first see whether the included polymorphisms have heterogeneous effects. We comprehensively investigated gene-obesity interactions between the TCF7L2-rs7903146 C > T polymorphism on T2D (prevalence and incidence) and analyzed other T2D-polymorphisms in a sub-sample. We studied 7018 PREDIMED …

Collaborative Musical Creativity between Students and Adults: The Sonorous Paella

2021

While creativity is a key element of contemporary curriculum frameworks around the world, it is still insufficiently fostered in formal education settings. This study analyzes a project for collaborative musical creativity, entitled The Sonorous Paella. Participants (N = 12) were eight Year 4 secondary students, two professional musicians, an artist-in-residence, and a music teacher. Drawing on a graphic musical score, the participants worked together for 1.5 months to produce a group composition and performance. They were provided with various sound producers (instruments, everyday objects, technological devices) and were encouraged to flexibly utilize the physical space to maximize collab…

Aortic valve and vascular calcium score in pre-TAVI CT: correlation with early post-procedural complications

2023

Abstract Purpose The aim of our study was to evaluate the prevalence of early complications after Transcatheter Aortic Valve Implantation (TAVI) and their correlation with the Calcium Score (CS) of the aortic valve, aorta and ilio-femoral arteries derived from pre-procedural computed tomography (CT). Materials and methods We retrospectively reviewed 226 patients (100 males, mean age 79.4 ± 6.7 years) undergoing 64-slice CT for pre-TAVI evaluation from January 2018 to April 2021. The population was divided into CS quartiles. Results Overall, 173 patients underwent TAVI procedure, of whom 61% presented paravalvular leak after the procedure, 28% presented bleeding or vascular complications, 25…

CKD NUTRITION, INFLAMMATION AND OXIDATIVE STRESS

2014

Introduction and Aims: Serum p-cresyl sulfate associates with cardiovascular disease in patients at different stages of chronic kidney disease. p-Cresyl sulfate concentrations are determined by intestinal uptake of p-cresol, human metabolism to p-cresyl sulfate and renal clearance. Whether intestinal uptake of p-cresol itself is associated with cardiovascular disease in patients with renal disease has not been studied to date. Methods: We performed a prospective study in patients with chronic kidney disease stage 1-5 (clinicaltrials.gov NCT00441623). Intestinal uptake of p-cresol, under steady state conditions, was estimated from 24h urinary excretion of p-cresyl sulfate. Primary endpoint w…

A combination of umbilical artery PI and normalized blood flow volume in the umbilical vein: Venous–arterial index for the prediction of fetal outcome

2008

Abstract Objective The objective was to assess the diagnostic power of the umbilical venous–arterial index (VAI) as a combination of the pulsatility index in the umbilical artery and the normalized blood flow volume in the umbilical vein for the prediction of poor fetal outcome. Study design This was a prospective clinical study in which the umbilical artery PI (UAPI), the normalized umbilical vein blood volume flow rate ( n UV; ml/min/kg estimated fetal body weight), the venous–arterial index (VAI; n UV/UAPI), and the pulsatility index (PI) in the umbilical artery (UA), uterine artery (utA), middle cerebral artery (MCA), and aorta were determined in 181 fetuses once (at between 17 and 41 w…
