Mapreduce-Enabled Scalable Nature-Inspired Approaches For Clustering, Ibrahim Mithgal Aljarah

Computer Science

The increasing volume of data to be analyzed imposes new challenges to the data mining methodologies. Traditional data mining such as clustering methods do not scale well with larger data sizes and are computationally expensive in terms of memory and time. Clustering large data sets has received attention in the last few years in several application areas such as document categorization, which is in urgent need of scalable approaches. Swarm intelligence algorithms have self-organizing features, which are used to share knowledge among swarm members to locate the best solution. These algorithms have been successfully applied to clustering, however, they suffer …

Manual Choice Reaction Times In The Rate-Domain., Cm Harris, J Waddington, V Biscione, S Manzi

School of Psychology

Over the last 150 years, human manual reaction times (RTs) have been recorded countless times. Yet, our understanding of them remains remarkably poor. RTs are highly variable with positively skewed frequency distributions, often modeled as an inverse Gaussian distribution reflecting a stochastic rise to threshold (diffusion process). However, latency distributions of saccades are very close to the reciprocal Normal, suggesting that "rate" (reciprocal RT) may be the more fundamental variable. We explored whether this phenomenon extends to choice manual RTs. We recorded two-alternative choice RTs from 24 subjects, each with 4 blocks of 200 trials with two task difficulties (easy …

English-Learning One- To Two-Year-Olds Do Not Show A Consonant Bias In Word Learning., Caroline Floccia, Thierry Nazzi, Luche C Delle, Silvana Poltrock, Jeremy Goslin

School of Psychology

Following the proposal that consonants are more involved than vowels in coding the lexicon (Nespor, Peña & Mehler, 2003), an early lexical consonant bias was found from age 1;2 in French but an equal sensitivity to consonants and vowels from 1;0 to 2;0 in English. As different tasks were used in French and English, we sought to clarify this ambiguity by using an interactive word-learning study similar to that used in French, with British-English-learning toddlers aged 1;4 and 1;11. Children were taught two CVC labels differing on either a consonant or vowel and tested on their pairing of a third …

Evaluating The Application Of Research-Based Guidance To The Design Of An Emergency Preparedness Leaflet., E. Hellier, J. Edworthy, L. Newbold, K. Titchener, M. Tucker, E. Gabe-Thomas

School of Psychology

UNLABELLED: Guidelines for the design of emergency communications were derived from primary research and interrogation of the literature. The guidelines were used to re-design a nuclear emergency preparedness leaflet routinely distributed to households in the local area. Pre-test measures of memory for, and self-reported understanding of, nuclear safety information were collected. The findings revealed high levels of non-receipt of the leaflet, and among those who did receive it, memory for safety advice was poor. Subjective evaluations of the trial leaflet suggested that it was preferred and judged easier to understand than the original. Objective measures of memory for the two …

The Craving Experience Questionnaire: A Brief, Theory-Based Measure Of Consummatory Desire And Craving, Jon May, Jackie Andrade, David J. Kavanagh, Gerald F.X. Feeney, Mathew J. Gullo, Dixie J. Statham, Jessica Skorka-Brown, Jennifer M. Connolly, Mandy Cassimatis, Ross Mcd Young, Jason P. Connor

School of Psychology

Aims: Research into craving is hampered by lack of theoretical specification and a plethora of substance-specific measures. This study aimed to develop a generic measure of craving based on Elaborated Intrusion (EI) Theory. Confirmatory Factor Analysis (CFA) examined whether a generic measure replicated the 3-factor structure of the Alcohol Craving Experience (ACE) scale over different consummatory targets and timeframes. Design: Twelve studies were pooled for CFA. Targets included alcohol, cigarettes, chocolate and food. Focal periods varied from the present moment to the previous week. Separate analyses were conducted for Strength and Frequency forms. Setting: Nine studies included university students, with …

A Biological, Latent Variable Model Of Health (Earlybird 68)., Michael E. Hyland, Alison N. Jeffery, Terence J. Wilkin

School of Psychology

OBJECTIVE: To determine whether factor analysis of a set of health-related biomarkers provides evidence of an underlying common dimension of variation, and to explore the relationship between this dimension of variation with positive and negative affect. METHOD: Twelve health-related metabolic, immune and body-composition biomarkers at ages 5, 7, 9, 11, 14 and 16years were obtained from the EarlyBird longitudinal cohort of 347 children and supplemented by positive affect (PA) and negative affect (NA) measured at age 16years. RESULTS: At each age, principal factor analysis revealed that nine of the 12 biomarkers consistently loaded on the first extracted factor, accounting for …

Introduction:

The aim of this study was to develop consensus recommendations on safety parameters for mobilizing adult, mechanically ventilated, intensive care unit (ICU) patients.

Methods:

A systematic literature review was followed by a meeting of 23 multidisciplinary ICU experts to seek consensus regarding the safe mobilization of mechanically ventilated patients.

Results:

Safety considerations were summarized in four categories: respiratory, cardiovascular, neurological and other. Consensus was achieved on all criteria for safe mobilization, with the exception being levels of vasoactive agents. Intubation via an endotracheal tube was not a contraindication to early mobilization and a fraction of inspired oxygen less than …
