Understanding Prediction Limits Through Unbiased Branches

2006

The majority of currently available branch predictors base their prediction accuracy on the previous k branch outcomes. Such predictors sustain high prediction accuracy but they do not consider the impact of unbiased branches which are difficult-to-predict. In this paper, we quantify and evaluate the impact of unbiased branches and show that any gain in prediction accuracy is proportional to the frequency of unbiased branches. By using the SPECcpu2000 integer benchmarks we show that there are a significant proportion of unbiased branches which severely impact on prediction accuracy (averaging between 6% and 24% depending on the prediction context used).

Los predictores clave de la reincidencia en participantes en un programa de intervención para agresores de pareja: un análisis de supervivencia

2020

ABSTRACT Strategies to reduce intimate partner violence against women (IPVAW) can be targeted at different levels. Batterer intervention programs (BIPs) are among the main treatment approaches for IPVAW offenders. The most common outcome used in the evaluation of BIP effectiveness is recidivism. Efforts to increase BIP effectiveness in reducing recidivism should focus on key predictive variables of this outcome. The aim of this study was to identify key predictors of official recidivism from a large set of variables drawn from a sample of IPVAW offenders court-mandated to a community-based BIP (N = 393), with a follow-up period of between 0 and 69 months. To this end, a survival analysis wa…

Usage and Dose Response of a Mobile Acceptance and Commitment Therapy App: Secondary Analysis of the Intervention Arm of a Randomized Controlled Trial

2016

Background: Mobile phone apps offer a promising medium to deliver psychological interventions. A mobile app based on Acceptance and Commitment Therapy (ACT) was developed and studied in a randomized controlled trial (RCT). Objective: To study usage metrics of a mobile ACT intervention and dose-response relationship between usage and improvement in psychological flexibility. Methods: An RCT was conducted to investigate the effectiveness of different lifestyle interventions for overweight people with psychological stress. This paper presents a secondary analysis of the group that received an 8-week mobile ACT intervention. Most of the analyzed 74 participants were female (n=64, 86%). Their me…

Predictive factors of physical activity in Spanish students based on their weight status

2018

El objetivo del presente estudio fue comparar la motivación autodeterminada hacia el ejercicio físico, autoconcepto físico, barreras hacia la actividad física e intención de ser físicamente activo entre adolescentes con y sin sobrepeso/obesidad. Una muestra de 333 escolares, de 13 a 16 años, participaron en esta investigación. Para la medición de las distintas variables se utilizaron instrumentos validados: Índice de masa corporal, Behavioral Regulation in Exercise Questionnaire, Physical Self Description Questionnaire, Autoinforme de Barreras para la Práctica de Ejercicio Físico e Intention to Be Physically Active Questionnaire. Los resultados mostraron diferencias estadísticamente signifi…

THE DEVELOPMENT OF ADOLESCENTS’ SELF-CONCEPT OF ABILITY THROUGH GRADES 7-9 AND THE ROLE OF PARENTAL BELIEFS

2016

This study examined the development of adolescents’ self-concept of ability in mathematics and literacy during secondary school, and the role that mothers’ and fathers’ beliefs concerning their child’s abilities play in this development. Also examined was whether the role of mothers’ and fathers’ beliefs about their adolescent child’s ability in mathematics and literacy differs according to the adolescent’s gender and level of performance. A total of 231 adolescents and their mothers and fathers were followed up across secondary school. The results showed, first, that adolescents’ self-concept of ability declined slightly from grade 7 to grade 9 in both mathematics and literacy. Second, mot…

PHYSICAL ACTIVITY IN ADOLESCENCE LEVELS CHANGES AND FACTORS OF INFLUENCE

2021

Physical activity (PA) is considered a health imperative, so it is understandable that physical inactivity imposes a serious health threat. The fact that alarming decline in physical activity levels (PALs) occurs in adolescence is particularly concerning. Accordingly, the dissertation deals with PA issues among adolescents in regular conditions and during the COVID-19 pandemic. Generally, changes and correlates of the PALs in the period from 14 to 18 years of age and in the period of the COVID-19 pandemic are investigated. Four presented studies analyze the specified problems in adolescents from Croatia and Bosnia and Herzegovina and are among the first studies that examined this issue in S…

Predictors of risk of learning disabilities

2012

Involves all the skills, knowledge and attitudes that are presumed to be precursors of the development of conventional forms of reading and writing (Whitehurst and Lonigan, 1998). It been traced a continuity of development between the first emergent literacy skills, starting from kindergarten, and early reading skills (Phillips BM et al). Children who have difficulty in the early stages of learning to read is very likely continue to present both in later school years further failures in this area (Cornoldi,Tressoldi, 2007) triggered a negative spiral and problematic process (Tressoldi e Vio, 1996). There are numerous empirical confirmation of the importance of early identification of diffic…

Abilità di apprendimento di lettura e scrittura in bambini in età prescolare e predittori di rischio

2014

The years from birth through age 5 are a critical time for children’s development and learning. Early childhood educators understand that at home and in early childhood education settings, young children learn important skills that can provide them with the cornerstones needed for the development of later academic skills. These patterns of learning in preschool are closely linked to later achievement: children who develop more skills in the preschool years perform better in the primary grades. The development of early skills appears to be particularly important in the area of literacy. It is estimated that more than a third of all graders (and an even higher percentage of our at-risk studen…

Values that Underlie and Undermine Well–Being: Variability across Countries

2017

We examined relations of 10 personal values to life satisfaction (LS) and depressive affect (DEP) in representative samples from 32/25 countries ( N = 121 495). We tested hypotheses both for direct relations and cross–level moderation of relations by Cultural Egalitarianism. We based hypotheses on the growth versus self–protection orientation and person–focus versus social–focus motivations that underlie values. As predicted, openness to change values (growth/person) correlated positively with subjective well–being (SWB: higher LS, lower DEP) and conservation values (self–protection/social) correlated negatively with SWB. The combination of underlying motivations also explained more comple…
