title: A quantitative investigation into the effectiveness of a 2x2, crossover, randomized control trial, for individuals suffering from non-specific chronic lower back pain, using a physical exercise-focused clinical intervention on the transverse abdominus/ multifidus (stability) and rectus abdominals/ erector spinae (dynamic) muscles.

subjects: lower back pain

abstract: A plethora of research has been conducted on interventions to reduce non-specific
lower back pain and improve the quality of life of sufferers. However, there is a lack of
distinction on the complementary nature of these interventions. Our primary research goal
was to assess the effectiveness of stability- and dynamic-style clinical interventions, focusing
on exercises to strengthen specific trunk muscles, including the transverse
abdominis/multifidus (stability-AB), and rectus abdominis/ erector spinae (dynamic). We
aimed to determine the effectiveness of these interventions in reducing non-specific chronic
lower back pain. Our research questions focused on whether a two-part clinical intervention
targeting specific core muscle groups (dynamic or stability) improves pain outcomes, whether
exercises targeting specific core muscle groups improve disability index physical impairment
and overall low back pain rating scale scores, and if there is a difference between intervention
groups and the sequential order of intervention for these outcomes. Additionally, we wanted
to investigate the correlation between these outcome measures and trunk endurance strength
scores. Seven participants were randomly assigned to either the stability (N =4) or dynamic
(N = 3) exercise group. Outcome measures included back and leg pain, lower back pain
visual analogue scale scores, disability index, physical impairment, and total Low Back Pain
Rating Scale (LBPRS) scores. Four measures of trunk endurance strength were taken using
Mcgill's Torso Endurance Test Battery (MTETB), which involves trunk extension, trunk
flexor, and trunk lateral tests on both the left and right sides. Assessments were performed
before the first clinical intervention, after the first intervention, and after the completion of
the final intervention. Each intervention phase lasted 4 weeks for each participant before they
switched to the opposing exercise group. The scores of back and leg pain, lower back pain,
disability index, and physical impairment all improved significantly after both interventions.
We found no difference between the groups during these intervention phases, or any potential
crossover/sequential effect, except for the dynamic group showing a significant improvement
in physical impairment scores after the first intervention, which remained consistent between
interventions one and two. In conclusion, both exercise approaches were similar across all
our outcome measures and may serve as complementary interventions for individuals
suffering from non-specific chronic low back pain.

title: Bring-Your-Own-Application (BYOA): Optimal stochastic application migration in mobile cloud computing

authors: Chase, Jonathan

abstract: The increasing popularity of using mobile devices in a work context, has led to the need to be able to support more powerful computation. Users no longer remain in an office or at home to conduct their activities, preferring libraries and cafes. In this paper, we consider a mobile cloud computing scenario in which users bring their own mobile devices and are offered a variety of equipment, e.g., desktop computer, smartTV, or projector, to migrate their applications to, so as to save battery life, improve usability and performance. We formulate a stochastic optimization problem to optimize the allocation of user applications to equipment despite future uncertainties. Furthermore, we extend the scenario to consider multiple locations and geographic migration. The performance evaluation shows the superior benefit, e.g., higher profit, compared with a baseline algorithm.

title: Systemic racism in clinical psychology: Symposia

authors: Wairoa-Harrison, Sophia

subjects: Racial oppression

abstract: This study constitutes a part of the Working to End Racial Oppression (WERO) project on Systemic Racism in Health Education, Training, and Practice. The focus is on the three dimensions of racism in psychology in Aotearoa New Zealand: its costs, systems and the potential responses that exist. Content: To set the scene, the session will begin with a 30-minute presentation that outlines evidence from three WERO studies on different levels of racism affecting indigenous Māori and minoritised groups. First study presents findings from a desktop analysis of papers across university psychology departments. The findings will be compared with previous studies (Levy, 2007; Levy & Waitoki, 2015) to identify the changes in inclusion of Māori and culturally focused paper at different timepoints. The second study involves semi-structured interviews with Māori students enrolled in clinical psychology training programmes (n = 19) to understand the extent of cultural responsiveness, support, disparities, and representation within programmes. The third study draws on preliminary survey findings with directors of training programmes to depict the progress towards including taha Māori and cultural competency in the psychology curriculum since the studies by Abbott and Durie (1987) and Nathan (1999). The rest of the session will be conducted as a wānanga or a forum that includes a panel discussion amongst WERO research team while allowing for a reciprocal exchange of knowledge with the attendees. Opportunities will be provided for attendees to ask questions, provide feedback to the research analyses and findings, and share their experiences of witnessing or encountering racism in psychology. The session will be opened with a karakia (prayer) and attendees to be offered manaakitanga (hospitality) and tikanga (custom) to ensure cultural safety. Goals: In this session, the research team will bring the evidence derived from robust analyses on existence and ramifications of racism in psychology to the fore. These findings will be integrated with the Waitangi Tribunal claim (Levy, 2018) to shed light on the manifestations of racism across systems and agents responsible for the regulation, training and employment of psychologists. Findings will be used to inform ways for all in psychology to embark on Te Tiriti-focused, culturally-competent and equitable approaches in the quest of indigenising the psychology discipline and advancing it to be relevant to the multicultural nature of Aotearoa populations.
