Personality Predictors Of Peer-Rated Adjustment And Likeability: A Three-Year Longitudinal Study, Patrick Heaven, Joseph Ciarrochi

joseph Ciarrochi

We hypothesized that girls would be more responsive than boys to opposite sex characteristics that indicated the likelihood of worldly success (i.e., academic ability) and pro-social behaviour (i.e., Conscientiousness (C), Agreeableness (A), and low Psychoticism (P)). Students (381 boys; 389 girls) completed individual difference measures in their first year of high school (Grade 7; Mean age 12.28) and then at approximate twelve month intervals for the next three years. Peer-rated adjustment and likeability ratings were obtained in Grades 9 and 10. Results indicated that the extent a girl viewed a boy as adjusted was influenced by that boy's level of …

On Being Mindful, Emotionally Aware, And More Resilient: Longitudinal Pilot Study Of Police Recruits, Joseph Ciarrochi, Frank Deane, Virginia Williams Jul 2015

On Being Mindful, Emotionally Aware, And More Resilient: Longitudinal Pilot Study Of Police Recruits, Joseph Ciarrochi, Frank Deane, Virginia Williams

joseph Ciarrochi

Police officers are at particular risk of stress when compared to people in other occupational groups. A compounding factor is that police are prone to the use of avoidant coping strategies when attempting to deal with this stress. Evidence suggests that “anti-avoidance” strategies, of acceptance, mindfulness and emotional awareness, are more effective ways of coping, and are linked to both mental health and personal effectiveness. This study followed 60 trainee police officers from the recruit phase into the workplace to determine if these processes predicted more positive mental health and wellbeing in police recruits after 1 year of service. Mindfulness …


Cognitive Ability And Health-Related Behaviors During Adolescence: A Prospective Study Across Five Years, Joseph Ciarrochi, Patrick Heaven, Timothy Skinner Jul 2015

Cognitive Ability And Health-Related Behaviors During Adolescence: A Prospective Study Across Five Years, Joseph Ciarrochi, Patrick Heaven, Timothy Skinner

joseph Ciarrochi

Longitudinal research on the links between intelligence and health behaviors among adolescents is rare. We report longitudinal data in which we assessed the relationships between intelligence as assessed in Grade 7 and consequential health outcomes in Grade 11. The mean age of respondents (N=420; 188 males, 232 females) was 12.30 years (SD=0.49) in Grade 7and 16.17 years (SD=0.45) in Grade 11. They completed standardized verbal and numerical ability tests and a measure of conscientiousness in Grade 7 and health related questions in Grade 11. Results indicated that higher intelligence was associated with a number of healthy behaviors including delay in …

The Relationship Between Self-Esteem And Academic Achievement In High Ability Students: Evidence From The Wollongong Youth Study., Wilma Vialle, Patrick C. L. Heaven, Joseph Ciarrochi

joseph Ciarrochi

The relationship between self-esteem and academic achievement is one that is regarded by many educators as a well-established fact. This belief has been often invoked in order to argue against the provision of ability grouping for gifted students. Refuting that commonly-held belief, this research examined the relationship between self-esteem and academic achievement in 65 high-ability secondary students, a sample drawn from a longitudinal study of over 900 students. The research demonstrated that there were no differences in measured selfesteem between the gifted and non-gifted students. More contentiously, though, the research found no correlation between self-esteem and academic achievement for the …

On Being Aware And Accepting: A One-Year Longitudinal Study Into Adolescent Well-Being, Joseph Ciarrochi, Todd Kashdan, Peter Leeson, Patrick Heaven, Carlie Jordan

joseph Ciarrochi

The nature and potential benefit of awareness and experiential acceptance in adolescence remains neglected and understudied. To address this gap in the literature, 776 students (50% female) in Grade 10 completed measures of mindfulness, emotional awareness, and experiential acceptance, as well as measures of major personality traits. To study prospective changes, assessments of emotional well-being were completed across a 1-year interval. Analyses revealed that “Acting with Awareness” (engaging fully in one’s current activity with undivided attention), emotional awareness, and experiential acceptance where all linked to prosocial tendencies and uniquely predicted increases in well-being across the year. Observing experience (noticing, observing, …


Relations Between Social And Emotional Competence And Mental Health: A Construct Validation Study, Joseph Ciarrochi, Gregory Scott, Frank Deane, Patrick Heaven Jul 2015

Relations Between Social And Emotional Competence And Mental Health: A Construct Validation Study, Joseph Ciarrochi, Gregory Scott, Frank Deane, Patrick Heaven

joseph Ciarrochi

Researchers working fairly independently of each other have created numerous measures of social and emotional competence (SEC). These measures tend to correlate (sometimes highly) with each other and with measures of stressful events, suggesting potential redundancy. We evaluated which, if any, SEC variables predicted unique variance in social and mental health after controlling for other SEC variables in the study and the impact of stressful events. Three-hundred and thirty-one university students participated in an anonymous, cross-sectional study. We measured stressful events, and a wide variety of SECs, including: social problem solving skill (effective problem orientation, automatic processing, and problem solving), …

The Role Of Emotion Identification Skill In The Formation Of Male And Female Friendships: A Longitudinal Study, H. Claire Rowsell, Joseph Ciarrochi, Patrick Heaven, Frank Deane

joseph Ciarrochi

The present study explored the relationship between emotion identification skill (EIS) and friendships in adolescence. Students from five Australian high schools completed questionnaires annually from Grade 8 to Grade 12 including subjective measures of EIS and a peer-based objective measure of social functioning (e.g., friendship nominations). The total sample of participants was 795 (406 males; 389 females) with 468 (225 males; 243 females) completing questionnaires in Grade 12. EIS in early adolescence was predictive of friendships for females in late adolescence. Specifically, girls starting out with low EIS in Grade 8 tended to have fewer female friendships and more male …

Improved Workflow Modelling Using Role Activity Diagram-Based Modelling With Application To A Radiology Service Case Study, Nagesh Shukla, John Keast, Darek Ceglarek

Nagesh Shukla

The modelling of complex workflows is an important problem-solving technique within healthcare settings. However, currently most of the workflow models use a simplified flow chart of patient flow obtained using on-site observations, groupbased debates and brainstorming sessions, together with historic patient data. This paper presents a systematic and semi-automatic methodology for knowledge acquisition with detailed process representation using sequential interviews of people in the key roles involved in the service delivery process. The proposed methodology allows the modelling of roles, interactions, actions, and decisions involved in the service delivery process. This approach is based on protocol generation and analysis techniques …

Anthony A Espinoza Mr

High dose rate (HDR) brachytherapy is a radiation treatment technique capable of delivering large dose rates to the tumor. Radiation is delivered using remote afterloaders to drive highly active sources (commonly 192Ir with an air KERMA strength range between 20 000 and 40 000 U, where 1 U = 1 uGy m2/h in air) through applicators directly into the patient's prescribed region of treatment. Due to the obvious ramifications of incorrect treatment while using such an active source, it is essential that there are methods for quality assurance (QA) that can directly and accurately verify the treatment plan and the …

Laboratory Study Of Small-Strain Behavior Of A Compacted Silty Sand, Ana Heitor, Buddhima Indraratna, Cholachat Rujikiatkamjorn Mar 2014

Laboratory Study Of Small-Strain Behavior Of A Compacted Silty Sand, Ana Heitor, Buddhima Indraratna, Cholachat Rujikiatkamjorn

Cholachat Rujikiatkamjorn

Small-strain behavior is a key indicator for assessing the performance of compacted fills. Compaction conditions, i.e., initial moisture content and applied energy, govern compaction effectiveness and thus, the structure and matric suction of compacted soil. This paper presents an experimental study of the small-strain behavior of compacted silty sand prepared with different compaction conditions. Specimens with varying initial moisture contents and compaction energies were tested with bender elements to determine the small-strain shear modulus (G0), while the post-compaction matric suction was measured using the filter paper method and tensiometer. The experimental data suggest a pronounced relationship between G0 and the …
