title: Work limitations 4 years after mild traumatic brain injury: A cohort study

authors: Theadom, Alice

subjects: Science & Technology

abstract: Objective
To explore employment status, work limitations, and productivity loss after mild traumatic brain injury (TBI).

Design
Inception cohort study over 4 years.

Setting
General community.

Participants
Adults (N=245; >16y at the time of injury) who experienced a mild TBI and who were employed prior to their injury.

Interventions
Not applicable.

Main Outcome Measures
Details of the injury, demographic information, and preinjury employment status were collected from medical records and self-report. Symptoms and mood were assessed 1 month postinjury using the Rivermead Post-Concussion Symptom Questionnaire and the Hospital Anxiety and Depression Scale. Postinjury employment status and work productivity were assessed 4 years postinjury using the Work Limitations Questionnaire.

Results
Four years after mild TBI, 17.3% of participants had exited the workforce (other than for reasons of retirement or to study) or had reduced their working hours compared with preinjury. A further 15.5% reported experiencing limitations at work because of their injury. Average work productivity loss was 3.6%. The symptom of taking longer to think 1 month postinjury significantly predicted work productivity loss 4 years later (β=.47, t=3.79, P≤.001).

Conclusions
Although changes in employment status and difficulties at work are likely over time, the results indicate increased unemployment rates, work limitations, and productivity loss in the longer term after a mild TBI. Identification of cognitive difficulties 1 month after TBI in working aged adults and subsequent interventions to address these difficulties are required to facilitate work productivity.

title: Measurement of natural convection heat transfer in an attic shaped enclosure

authors: Anderson, Timothy Nicholas

subjects: solar

abstract: Heat transfer by natural convection in triangular enclosures is an area of significant importance in applications such as the design of greenhouses, attics and solar water heaters. However, given its significance to these areas it has not been widely examined. In this study, the natural convection heat transfer coefficients for air in an attic shaped enclosure were determined for Grashof Numbers over the range of 10⁷ to 10⁹. It was found that the measured heat transfer coefficients could be predicted to within 5% by Ridouane and Campo’ (2005) equation (Eqn. 1) for natural convection in a triangular enclosure previously developed for Grashof Numbers in the range 10⁵ and 10⁶. 
Nu= 0.286A⁻⁰•²⁸⁶ Gr¼    (1)
As such, it is suggested that this equation may be suitable for predicting the natural convection heat transfer coefficients in full scale attic enclosures.

title: Riariakina ō rongo hirikapo From kōhanga reo to kura

authors: Hohepa, Margie Kahukura

abstract: Ko te kaupapa tonu, ko te whakatupu i te mahara o te hirikapo kia tiu ai ki te muri, arā, kia puta he whakaaro i pokepokengia nō roto tonu i ngā whakahekenga kāwai o ngā tūpuna o te tamaiti, kua maranga te wā e kaumātua haere ana te tamaiti, ngōna kanohi kua huaki, ngōna taringa kua pīkari, ngā whakaaro kua korikori, tōna wairua hīkaka kua ngawhā, ngērā kaupapa katoa o te tamaiti i taua wā o te tupu. Mā tēnei kōrero hoki hei kawe te taonga o te rongo hirikapo, arā, ngā whakaaro, ngā mahara, nāna ko te waha, nā te waha ko te kupu kōrero e makere iho ai i te ārero tarapepe. Heoi anō he tohutohu anō kei roto e kī ana, manaakingia ngā kai o te hirikapo o te tamaiti, he taonga. Ki te kore e tika te manaakingia e ngā mātua, tērā te wā ka ātitirauhea i te puāwaitanga o te rau. Ngērā kaupapa katoa. (Haki Tuaupiki, 2013)
This project grew out of the desire of a kōhanga and a kura—Te Kōhanga Reo o Ngā Kuaka and Tōku Māpihi Maurea Kura Kaupapa Māori respectively—to enhance transitions between their two sites for tamariki and whānau. Although visits to Tōku Māpihi Maurea before beginning at the kura were available for Ngā Kuaka tamariki on acceptance for enrolment, the instigators of this project believed a more formal transition programme would be beneficial to tamariki and their whānau. The kōhanga and kura were interested in tamariki and whānau experiencing a more effective transition across the two environments and the learning and curriculum in those respective sites.
The kōhanga and kura approached researchers at the University of Waikato Te Kura Toi Tangata Faculty of Education with the research question below and together we developed the proposal. From the outset the project was collaborative, cross-sector, and involved researchers from the kōhanga, the kura and the university.
