Smartphone use and study behavior: A Korean and Australian comparison
No full textSmartphone use amongst university students is widespread and a common practice while studying. However, this usage can lead to academic performance costs. This study examined the relationship between smartphone use during study, problematic smartphone use and academic performance in Korean and Australian university students. 119 Korean and 270 Australian students aged between 18 and 26 years completed a survey comprised of a smartphone usage questionnaire, smartphone addiction scale and self-report of their current GPA score. Average smartphone use and problematic smartphone use were found to be significantly higher for Korean compared to Australian students. A positive relationship was found between smartphone use and problematic smartphone use. For Australian students, a negative relationship was found between smartphone use and GPA. Results indicate that smartphone use and smartphone addiction proneness are currently higher for Korean students compared to Australian students. Furthermore, the more time a student spends using their smartphone, the more at risk they are for problematic smartphone use and possible academic performance costs
Work harassment in the UK and US nursing context
No full textThis paper examines one type of negative work behaviour, work harassment, using two theoretical frameworks: Social Exchange Theory (SET) and Similarity-Attraction (SA). SET explains work harassment as a product of poor management practices, whereas using SA theory explains it as a result of the growing normalisation of high workloads. The study undertakes latent mean and path model comparison analysis using structural equation modelling of data from 189 nurses in the UK and 401 nurses in the USA. The findings indicate a good model fit showing a significant path from Leader Member Exchange (LMX) to work harassment, wellbeing and subsequent turnover intentions, with LMX fully mediating the path from LMX to wellbeing for UK nurses, but only partially mediating the same path for nurses in the USA. The findings suggest SET provides a better explanation for work harassment for UK nurses, whereas SA theory better explains the US nurse experience
Positive impacts of a university walking program: a case study
No full textA sedentary lifestyle is a key contributor to chronic disease, and many occupations in our society are sedentary in nature. Therefore, a main focus of workplace health promotion programs is to increase employee physical activity. In addition, workplaces are an ideal arena to deliver health programming, however many organizations face barriers to implementation, such as staffing, budget and time constraints. The purpose of this case study is to present a real world, cost-effective workplace walking program that positively impacted employee health. Feedback will also be provided on challenges encountered in relation to compliance and retention. Finally, practical, and social applications are discussed
An analysis of Twitter discourse regarding identifying language for people on the autism spectrum
No full textPerson-first language, to refer to a person with autism, has been dominant within peer-reviewed literature; however, there are autistic people who prefer identity-first language. This is a shift from the language championed within mental health nursing; therefore it is important to understand the meaning and actions within identifying language. This analysis of 29,606 words of Twitter discourse explored the political struggle between the modes of language. Differences within the conceptualisation of autism and disability underpinned varied subject positions and the rearticulation of autism and expertise was identified. Contextually driven adoption of identifying language requires awareness of the potential benefits and consequences
Remobilization and fate of sulphur in mustard
No full textBackground and Aims
Sulphur (S) is an essential macronutrient involved in numerous metabolic pathways required for plant growth. Crops of the plant family Brassicaceae require more S compared with other crops for optimum growth and yield, with most S ultimately sequestered in the mature seeds as the storage proteins cruciferin and napin, along with the unique S-rich secondary metabolite glucosinolate (GSL). It is well established that S assimilation primarily takes place in the shoots rather than roots, and that sulphate is the major form in which S is transported and stored in plants. We carried out a developmental S audit to establish the net fluxes of S in two lines of Brassica juncea mustard where seed GSL content differed but resulted in no yield penalty. Methods
We quantified S pools (sulphate, GSL and total S) in different organs at multiple growth stages until maturity, which also allowed us to test the hypothesis that leaf S, accumulated as a primary S sink, becomes remobilized as a secondary source to meet the requirements of GSL as the dominant seed S sink. Key Results
Maximum plant sulphate accumulation had occurred by floral initiation in both lines, at which time most of the sulphate was found in the leaves, confirming its role as the primary S sink. Up to 52 % of total sulphate accumulated by the low-GSL plants was lost through senesced leaves. In contrast, S from senescing leaves of the high-GSL line was remobilized to other tissues, with GSL accumulating in the seed from commencement of silique filling until maturity. Conclusion
We have established that leaf S compounds that accumulated as primary S sinks at early developmental stages in condiment type B. juncea become remobilized as a secondary S source to meet the demand for GSL as the dominant seed S sink at maturity
‘Nothing goes to waste’: a professional learning programme for early childhood centres
No full textWaste created by modern lifestyles is of key concern to sustainable development globally. Early childhood centres engage in sustainable practices, and waste management is one of these practices. Past research has indicated that early childhood staff are challenged to implement sustainable practices. However, the National Quality Standard requires centres to engage in sustainable practices. This study reports on research undertaken to examine the effectiveness of effectiveness of a waste management professional learning programme run in 30 early childhood centres in Australia. The data collected was interviews of the directors of 16 centres, 6 months after the programme. Findings found the programme to be effective in encouraging waste management practices as all centres changed practices to reduce or recycle waste. The majority of the centres had a staff member who championed environmental education and was an inspiration for other staff, but barriers to good waste management practices were experienced because of external stakeholders’ power over decision-making, owners not agreeing to make changes, and, internally, from having to maintain hygienic standards. Recommendations are made for future professional learning programmes
Presence of a basic secretory protein in xylem sap and shoots of poplar in winter and its physicochemical activities against winter environmental conditions
No full textXSP25, previously shown to be the most abundant hydrophilic protein in xylem sap of Populus nigra in winter, belongs to a secretory protein family in which the arrangement of basic and acidic amino acids is conserved between dicotyledonous and monocotyledonous species. Its gene expression was observed at the same level in roots and shoots under long-day conditions, but highly induced under short-day conditions and at low temperatures in roots, especially in endodermis and xylem parenchyma in the root hair region of Populus trichocarpa, and its protein level was high in dormant buds, but not in roots or branches. Addition of recombinant PtXSP25 protein mitigated the denaturation of lactate dehydrogenase by drying, but showed only a slight effect on that caused by freeze–thaw cycling. Recombinant PtXSP25 protein also showed ice recrystallization inhibition activity to reduce the size of ice crystals, but had no antifreezing activity. We suggest that PtXSP25 protein produced in shoots and/or in roots under short-day conditions and at non-freezing low temperatures followed by translocation via xylem sap to shoot apoplast may protect the integrity of the plasma membrane and cell wall functions from freezing and drying damage in winter environmental conditions
The state of the evidence for whole-system, multi-modality naturopathic medicine: a systematic scoping review
No full textObjective: To summarize the current state of the research evidence for whole-system, multi-modality naturopathic medicine. Design: A systematic search for research articles from around the world was undertaken using MEDLINE, Embase, CINAHL, AMED, and WHO regional indexes. Naturopathic journals and gray literature were hand searched. No language restrictions were imposed.Interventions: All human research evaluating the effectiveness of naturopathic medicine, where two or more naturopathic modalities are delivered by naturopathic clinicians, were included in the review. Case studies of five or more cases were included.Results: Thirty-three published studies (n = 9859) met inclusion criteria (11 American; 4 Canadian; 6 German; 7 Indian; 3 Australian; 1 United Kingdom; and 1 Japanese) across a range of mainly chronic clinical conditions. The studies predominantly showed evidence for the efficacy of naturopathic medicine for the conditions and settings in which they were based. Conclusions: To date, research in whole-system, multi-modality naturopathic medicine shows that it is effective for treating cardiovascular disease, musculoskeletal pain, type 2 diabetes, polycystic ovary syndrome, depression, anxiety, and a range of complex chronic conditions
Administering faith: does the religious institution administering a school influence educational achievement?
No full textAustralia’s education landscape is almost unique among developed nations in having a high proportion of students taught at non-government schools by a diverse range of religious providers, which receive relatively high levels of government funding. It therefore offers the ideal setting for a study on the outcomes achieved by students at schools administered by the major faith providers relative to their peers in government institutions. We take advantage of a six-year panel of nationwide academic test data, along with a comprehensive suite of control variables, to test whether there are differences in average school performance. We find strong evidence to suggest that significant differences in achievement exist between various faith-based providers that cannot be explained solely with reference to educational advantage and prior performance
