Book Review Of J. L. Collins And V. Mayer (2010) Both Hands Tied: Welfare Reform And The Race To The Bottom Of The Low-Wage Labor Market, Scott Burrows

Faculty of Arts - Papers (Archive)

Jane L Collins and Victoria Mayer's book, Both Hands Tied: Welfare Reform and the Race to the Bottom of the Low-Wage Labor Market provides a timely analysis on the state of contemporary welfare reform in the USA with a focus on the lives of 33 women in Milwaukee and Racine, Wisconsin, As the book notes, these areas were formerly manufacturing centres but in the recent years have experienced deindustrialization and an emergent service-based economy that continues to have quite dramatic effects on the lives of low-wage workers.

The Interaction Of Body Armor, Low-Intensity Exercise, And Hot-Humid Conditions On Physiological Strain And Cognitive Function, Joanne N. Caldwell, Lian Engelen, Charles Van Der Henst, Mark J. Patterson, Nigel A.S Taylor

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: This project was aimed at evaluating the impact of combat armor on physiological and cognitive functions during low-intensity exercise in hot-humid conditions (36°C and 60% relative humidity). Methods: Nine males participated in three trials (2.5 hours), walking at two speeds and wearing different protective equipment: control (combat uniform and cloth hat); torso armor with uniform and cloth hat; and full armor (uniform, torso armor, and helmet). Results: As time progressed, core temperatures increased and deviated signifi cantly among trials, rising at 0.37°C h −1 (control), 0.41°C h −1 (torso armor), and 0.51°C h −1 (full armor). Heart rates also …

Effects Of High And Low Breast Support On Breast Kinematics And Kinetics During Treadmill Running, Deirdre Mcghee, Julie R. Steele, William J. Zealey

Faculty of Health and Behavioural Sciences - Papers (Archive)

Results: The mean vertical component of the peak bra/breast spring force during treadmill running was greatest during the downward breast trajectory and was approximately 30% less in the high breast support condition (13 N ± 7 N) compared to the low support condition (17 N ± 10 N). This force reduction was accompanied by a 300% decrease in breast and bra discomfort. Conclusion: Wearing a well-fitted supportive sports bra is recommended for females with large breasts to reduce the breast forces and, in tum, exercise induced breast and bra discomfort during physical activity such as treadmill running.

Aripiprazole Differentially Affects Mesolimbic And Nigrostriatal Dopaminergic Transmission: Implications For Long-Term Drug Efficacy And Low Extrapyramidal Side-Effects, Xu-Feng Huang, Chao Deng, Mei Han

Faculty of Health and Behavioural Sciences - Papers (Archive)

Aripiprazole has been used effectively to treat schizophrenia in the clinic ; however, its mechanisms ofaction are not clear. This study examined how short- and long-term aripiprazole treatment affects dopaminergic transmission in mesolimbic and nigrostriatal pathways. For comparison, the effects of haloperidol and olanzapine treatment were also examined. Aripiprazole significantly increased D2 receptor mRNA expression and decreased tyrosine hydroxylase (TH) mRNA expression in the ventral tegmental area (VTA) after 1- and 12-wk treatment, but had no effect in substantia nigra (SN) and nucleus accumbens (NAc). Aripiprazole also decreased dopamine transporter (DAT) binding density in NAc (for 1- and 12- wk …

A Food-Based Dietary Strategy Lowers Blood Pressure In A Low Socio-Economic Setting: A Randomised Study In South Africa, Karen E. Charlton, Naomi Levitt, Krisela Steyn, Deborah Jonathan, Nomonde Gwebushe, Nasheeta Peer, Katja Rossouw, Theresa Gogela, Carl J. Lombard

Objective To assess the impact of a food-based intervention on blood pressure (BP) in free-living South African men and women aged 50–75 years, with drug-treated mild-to-moderate hypertension.

Methods A double-blind controlled trial was undertaken in eighty drug-treated mild-to-moderate hypertensive subjects randomised to an intervention (n 40) or control (n 40) arm. The intervention was 8-week provision of six food items with a modified cation content (salt replacement (SOLO™), bread, margarine, stock cubes, soup mix and a flavour enhancer) and 500 ml of maas (fermented milk)/d. The control diet provided the same quantities of the targeted foods but of …

Prevalence Of Low Serum Folate And Vitamin B12 In An Older Australian Population, Victoria M. Flood, Wayne T. Smith, Karen L. Webb, Elena Rochtchina, Valerie Anderson, Paul Mitchell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: To examine the prevalence of low serum folate and vitamin B12, in association with elevated serum homocysteine, in a representative sample of older Australians. Methods: During 1997-2000, 3,508 persons aged 50+ years were examined in a population-based cohort study conducted in two postcodes, west of Sydney, Australia. Of these, 2,901 participants (82.7%) provided fasting blood for estimates of serum folate, vitamin B12 and total homocysteine. Results: Low serum B12 (<185 pmol>/L) was found in 22.9% of participants and low serum folate (<6.8 nmol/L) in 2.3% of participants. Among those people with very low serum vitamin B12 (<125 pmol/L) and low serum folate, 51% had elevated homocysteine. Conclusions: Low serum levels of vitamin B12 and elevated serum homocysteine are relatively frequent in older Australians. Implications: Appropriate public health action should be considered to reduce the prevalence of low serum vitamin B12 and elevated homocysteine in older Australians.

Low-Dose/High-Concentration Localized Botulinum Toxin A Improves Upper Limb Movement And Function In Children With Hemiplegic Cerebral Palsy, Kevin Lowe, Iona Novak, Anne Cusick

Faculty of Health and Behavioural Sciences - Papers (Archive)

The objective was to determine the effects of low-dose, highconcentration, dual localized botulinum toxin A (BTX-A) injections on upper limb movement quality and function. Study design was an evaluator-blinded, randomized, controlled trial. Forty-two children (31 males, 11 females; range 2–8y, mean 4y [SD 1.6]) with hemiplegic cerebral palsy (Gross Motor Function Classification System level I)participated. All received occupational therapy. The treatment group (n=21) received one injection series (mean muscles injected 6 [SD 1.05]; total dose 82–220 units, mean 139 [SD 37.48]; dilution 100 units/0.5ml). Primary outcome of Quality of Upper Extremity Skills Test (QUEST) at 6 months was not significant …
