Dreaming in Two Worlds and Two Languages: Bilingual Dreams and Acculturation Challenges
This study investigated the significance of first and second languages in the bilingual dreams of immigrant participants. A purposive sample of nine women and six men aged 20 to 71 whose first languages were Spanish, Thai, Italian, Tagalog, and French, and later acquired English, participated in semi-structured, open-ended interviews recalling a dream featuring both languages. Transcripts were thematically analyzed individually and across cases. The most important theme was the ambicultural self in the dream, referring to a culturally flexible dream figure able to speak the dreamerâs first and second languages to bridge between the protagonistâs two cultures to accomplish the dream task of somehow resolving cultural conflicts. The ambicultural self and dream tasks reflected challenges identified in Berryâs acculturation model. Therapists can use bilingual dreams to help clients explore cultural identity conflicts and become more cross-culturally competent
Sensory Evaluation of Ice Cream made with Prebiotic Ingredients
Fructooligosaccharides (FOS) and inulin are considered prebiotic ingredients and are FDA approved for use in food for human consumption. A prebiotic is a food ingredient that benefits the host by selectively stimulating the growth and activity of the beneficial bacteria in the colon. In this project, consumer acceptability of ice cream made with 10% of the sugar substituted with either inulin or FOS was tested. Physical tests were also conducted. The texture, water activity and L and b color values did not differ significantly for the treatments (Inulin and FOS) versus the control sample. The a value for color (red/green) differed (p=0.02) for the treatment samples when compared to the control. For the sensory evaluation, 71 participants ranked the ice cream samples made with inulin and FOS equally as well liked (6.56 and 6.80, respectively) on a 17 cm hedonic scale (0 = like and 17 = dislike). However, the participants liked the control ice cream better than the ice cream with a prebiotic ingredient (P\u3c0.001). Inulin and FOS are potential ingredients for use in ice cream
The bronchodilator response in preschool children: A systematic review
BACKGROUND: The bronchodilator response (BDR) is frequently used to support diagnostic and therapeutic decision-making for children who wheeze. However, there is little evidence-based guidance describing the role of BDR testing in preschool children and it is unclear whether published cut-off values, which are derived from adult data, can be applied to this population. METHODS: We searched MEDLINE, EMBASE, Web of Science, and Cochrane databases (inception-September 2015) for studies reporting response to a bronchodilator in healthy preschool children, response following placebo inhalation, and the diagnostic efficacy of BDR compared with a clinical diagnosis of asthma/recurrent wheezing. FINDINGS: We included 14 studies. Thirteen studies provided BDR data from healthy preschool children. Two studies reported response to placebo in preschool children with asthma/recurrent wheezing. Twelve studies compared BDR measurements from preschool children with asthma/recurrent wheeze to those from healthy children and seven of these studies reported diagnostic efficacy. Significant differences between the BDR measured in healthy preschool children compared with that in children with asthma/recurrent wheeze were demonstrated in some, but not all studies. Techniques such as interrupter resistance, oscillometry, and plethysmography were more consistently successfully completed than spirometry. Between study heterogeneity precluded determination of an optimum technique. INTERPRETATION: There is little evidence to suggest spirometry-based BDR can be used in the clinical assessment of preschool children who wheeze. Further evaluation of simple alternative techniques is required. Future studies should recruit children in whom airways disease is suspected and should evaluate the ability of BDR testing to predict treatment response
Evalaution and optimization of laser cutting parameters for plywood materials
Laser process parameters influence greatly the width of kerfs and quality of the cut edges. This article reports experiments on the laser plywood-cutting performance of a CW 1.5 kW CO2ÂŹ Rofin laser, based on design of experiments (DOE). The laser was used to cut three thicknesses 3, 6 and 9 mm of plywood panels. The process factors investigated are: laser power, cutting speed, air pressure and focal point position. The aim of this work is to relate the cutting edge quality parameters namely: upper kerf (UK), lower kerf (LK), the ratio between upper to lower kerfs and the operating cost to the process parameters mentioned above. Mathematical models were developed to establish the relationship between the process parameters and the edge quality parameters, and special graphs were drawn for this purpose. Finally, a numerical optimization was performed to find out the optimal process setting at which both kerfs would lead to a ratio of about 1, and at which low cutting cost take place
Australian consumer perspectives, attitudes and behaviours on antibiotic use and antibiotic resistance: A qualitative study with implications for public health policy and practice
© 2017 The Author(s). Background: Consumers receive over 27 million antibiotic prescriptions annually in Australian primary healthcare. Hence, consumers are a key group to engage in the fight against antibiotic resistance. There is a paucity of research pertaining to consumers in the Australian healthcare environment. This study aimed to investigate the perspectives, attitudes and behaviours of Australian consumers on antibiotic use and antibiotic resistance, to inform national programs for reducing inappropriate antibiotic consumption. Method: Semi-structured interviews with 32 consumers recruited via convenience and snowball sampling from a university population in South East Queensland. Interview transcripts were deductively and inductively coded. Main themes were identified using iterative thematic analysis. Results: Three themes emerged from the analysis, to elucidate factors affecting antibiotic use: (a) prescription type; (b) consumer attitudes, behaviours, skills and knowledge; and (c) consumer engagement with antibiotic resistance. Consumers held mixed views regarding the use of delayed antibiotic prescriptions, and were often not made aware of the use of repeat antibiotic prescriptions. Consumers with regular general practitioners were more likely to have shared expectations regarding minimising the use of antibiotics. Even so, advice or information mediated by general practitioners was influential with all consumers; and helped to prevent inappropriate antibiotic use behaviours. Consumers were not aware of the free Return of Unwanted Medicines service offered by pharmacies and disposed of leftover antibiotics through household waste. To engage with mitigating antibiotic resistance, consumers required specific information. Previous public health campaigns raising awareness of antibiotics were largely not seen by this sample of consumers. Conclusions: Australian consumers have specific information needs regarding prescribed antibiotics to enable appropriate antibiotic use behaviours. Consumers also have expectations for high quality general practice consults conducted in a manner that increases consumer confidence in the treatment decision, regardless of whether an antibiotic is prescribed. To reduce inappropriate consumption of antibiotics and to more fully engage Australian consumers in mitigating antibiotic resistance, changes in health policy and practice are required
Robust Upward Dispersion of the Neutron Spin Resonance in the Heavy Fermion Superconductor CeYbCoIn
The neutron spin resonance is a collective magnetic excitation that appears
in copper oxide, iron pnictide, and heavy fermion unconventional
superconductors. Although the resonance is commonly associated with a
spin-exciton due to the ()-wave symmetry of the superconducting
order parameter, it has also been proposed to be a magnon-like excitation
appearing in the superconducting state. Here we use inelastic neutron
scattering to demonstrate that the resonance in the heavy fermion
superconductor CeYbCoIn with has a ring-like
upward dispersion that is robust against Yb-doping. By comparing our
experimental data with random phase approximation calculation using the
electronic structure and the momentum dependence of the -wave
superconducting gap determined from scanning tunneling microscopy for
CeCoIn, we conclude the robust upward dispersing resonance mode in
CeYbCoIn is inconsistent with the downward dispersion
predicted within the spin-exciton scenario.Comment: Supplementary Information available upon reques
