Bullying in physical education : its prevalence & impact on the intention to continue secondary school physical education

The purpose of this study was to determine the prevalence of bullying in physical education and its influence on students' intention to participate in the class in the future. Additionally, the study researched the relationship between bullying and body image as well as bullying and physical competency in physical education. A survey was utilized that collected both quantitative and qualitative data about students' experiences in physical education. Two-hundred and thirty-four grade 10 students (144 female and 90 male) from 8 different secondary schools participated in the study. Data analyses were completed using the Statistical Package for the Social Sciences (SPSS) version 16.0. Results showed thaLapproximately 18.3% of respondents had .experienced physical bullying in physical education; 23.7% had experienced verbal bullying; and 20.4% experienced social bullying. Furthermore, those who experienced frequent bullying in physical education did not intend on taking the class in the future. The relationship between body image and bullying was not found to be significant. However, physical competence was found to significantly predict bullying in physical education. These results show how prevalent bullying is in physical education classes and how it negatively impacts future participation in the class.

Communicating information about medication side effects: effects on satisfaction, perceived risk to health, and intention to comply

Previous research has shown that people's evaluations of explanations about medication and their intention to comply with the prescription are detrimentally affected by the inclusion of information about adverse side effects of the medication. The present study (Experiment 1) examined which particular aspects of information about side effects (their number, likelihood of occurrence, or severity) are likely to have the greatest effect on people's satisfaction, perception of risk, and intention to comply, as well as how the information about side effects interacts with information about the severity of the illness for which the medication was prescribed. Across all measures, it was found that manipulations of side effect severity had the greatest impact on people's judgements, followed by manipulations of side effect likelihood and then number. Experiments 2 and 3 examined how the severity of the diagnosed illness and information about negative side effects interact with two other factors suggested by Social Cognition models of health behaviour to affect people's intention to comply: namely, perceived benefit of taking the prescribed drug, and the perceived level of control over preventing or alleviating the side effects. It was found that providing people with a statement about the positive benefit of taking the medication had relatively little effect on judgements, whereas informing them about how to reduce the chances of experiencing the side effects had an overall beneficial effect on ratings.

Interpreting information about medication side effects: differences in risk perception and intention to comply when medicines are prescribed for adults or young children

This study investigates whether, and how, people's perception of risk and intended health behaviours are affected by whether a medicine is prescribed for themselves or for a young child. The question is relevant to the issue of whether it is beneficial to produce medicines information that is tailored to particular subgroups of the population, such as parents of young children. In the experiment, participants read scenarios which referred either to themselves or their (imagined) 1-year-old child, and were required to make a number of risk judgements. The results showed that both parents and non-parents were less satisfied, perceived side effects to be more severe and more likely to occur, risk to health to be higher, and said that they would be less likely to take (or give) the medicine when the recipient was the child. On the basis of the findings, it is suggested that it may well be beneficial to tailor materials to broader classes of patient type.

Which words are hard for autistic children to learn?

Motivated by accounts of concept use in autistic spectrum disorder (ASD), and a computational model of weak central coherence (O’Loughlin & Thagard, 2000) we examined comprehension and production vocabulary in typically-developing children, and those with ASD and Down syndrome (DS). Controlling for frequency, familiarity, length, and imageability, Colorado Meaningfulness played a hitherto unremarked role in the vocabularies of children with ASD. High Colorado Meaningful words were underrepresented in the comprehension vocabularies of 2- to 12-year-olds with ASD. The Colorado Meaningfulness of a word is a measure of how many words can be associated with it. Situations in which high Colorado Meaningfulness words are encountered are typically highly variable, and words with High Colorado Meaningfulness often involve extensive use of context. Our data suggest that the number of contexts in which a particular word can appear has a role in determining vocabulary in ASD. This suggestion is consistent with the weak central coherence theory of autism.

A hybrid approach to learn with imbalanced classes using evolutionary algorithms

There is an increasing interest in the application of Evolutionary Algorithms (EAs) to induce classification rules. This hybrid approach can benefit areas where classical methods for rule induction have not been very successful. One example is the induction of classification rules in imbalanced domains. Imbalanced data occur when one or more classes heavily outnumber other classes. Frequently, classical machine learning (ML) classifiers are not able to learn in the presence of imbalanced data sets, inducing classification models that always predict the most numerous classes. In this work, we propose a novel hybrid approach to deal with this problem. We create several balanced data sets with all minority class cases and a random sample of majority class cases. These balanced data sets are fed to classical ML systems that produce rule sets. The rule sets are combined creating a pool of rules and an EA is used to build a classifier from this pool of rules. This hybrid approach has some advantages over undersampling, since it reduces the amount of discarded information, and some advantages over oversampling, since it avoids overfitting. The proposed approach was experimentally analysed and the experimental results show an improvement in the classification performance measured as the area under the receiver operating characteristics (ROC) curve.

Intention to create legal relations: the end of presumptions

Traditionally, courts have presumed that commercial parties intend to create legal relations when entering into agreements and that family members do not. Although not without their critics, until recently these twin presumptions appeared immutable. This article examines the trend to reduce the emphasis on these presumptions by some members of the judiciary in the selection of Australian and New Zealand cases and proposes that as a consequence of the High Court's decision in Ermogenous v Greek Orthodox Community of SA Inc (2002) 209 CLR 95 the intention to create legal relations presumptions should no longer be used in any context. It concludes by considering the implications for this area of law.

Prediction intention to quit in the call centre industry: does the retail model fit?

Purpose – Models of workplace turnover are rarely assessed in contexts other than that in which they were developed. This reduces their generalizability and their usefulness in providing managers with guidance as to what they might do to reduce workers intentions to quit. The purpose of this study is to test a model derived from a study of shop floor retail salespeople in the call centre environment.

Design/methodology/approach – A questionnaire measuring the variables in the model was completed by 126 call centre representatives recruited from 11 call centres in Melbourne, Australia.

Findings – Although the model was supported, the interactions among the variables differed. In particular, stressors played a bigger, albeit indirect, role in the intention to quit.

Practical implications – Call centre managers need to consider carefully the aspects of the work environment that may be stressful. If appropriately addressed, turnover may be reduced, and productivity increased.

Originality/value – This paper demonstrates that the model of turnover derived from shop floor salespeople is generally robust in the call centre setting. It provides management of call centres with some guidance as to the factors associated with turnover and areas that can be addressed to reduce it.

How can managers reduce employee intention to quit?

This paper reports on an investigation of the variables that may be predictive of intentions to leave a job, and tests a model that includes mediating variables. A total of 173 retail salespeople completed questionnaires measuring commitment to the organization for which they worked, job satisfaction, stress, supervisor support, locus of control, self-esteem, the perceived stressors in the job and their intention to quit. Path analysis was used to test the relationships hypothesized in the model. The majority of hypotheses were supported, with the variables included accounting for 52 per cent of the variance in intention to quit. Emotional support from supervisors and self-esteem mediated the impact of stressors on stress reactions, job satisfaction, commitment to the organization and intention to quit. It is suggested that to ameliorate intention to quit and in turn reduce turnover, managers need to actively monitor workloads, and the relationships between supervisors and subordinates in order to reduce and manage stress. Managers also need to monitor both the extrinsic and intrinsic sources of job satisfaction available to employees. These activities could assist in maintaining and increasing job satisfaction and commitment to the organization.

Pregnant women's alcohol consumption : the predictive utility of intention to drink and prepregnancy drinking behaviour

Objective: This study had two aims: (1) to examine pregnant women's alcohol consumption across time from prepregnancy until childbirth and (2) to explore whether prepregnancy drinking and intention to drink predict prenatal alcohol consumption while controlling for relevant demographic variables.

Methods: At 17–21 weeks, 248 pregnant women completed questions about demographics, intention to drink alcohol during the subsequent pregnancy, and retrospective measures of prepregnancy and early pregnancy consumption. After this time, calendars were sent fortnightly assessing daily alcohol consumption until birth.

Results: For women who drank both prepregnancy and postpregnancy confirmation, average fortnight alcohol consumption in the first weeks of pregnancy was lower than during prepregnancy, and consumption continued to decrease between gestational weeks 1 and 8, particularly following pregnancy confirmation, after which it remained relatively stable. When predicting whether women drank in late pregnancy, intention accounted for unique variance after controlling for income and prepregnancy drinking. For women who drank after pregnancy confirmation, prepregnancy drinking quantity significantly predicted intention to drink, which in turn predicted fortnight alcohol consumption in later pregnancy, after controlling for prepregnancy drinking and income.

Conclusions: Findings highlight the need to measure alcohol consumption at multiple time points across pregnancy, the need for educating and supporting women to reduce consumption when planning pregnancies, and the usefulness of intention to drink as a predictor of drinking during pregnancy.

Intention to claim a Medicare rebate among women receiving private Victorian pregnancy termination service

Objectives: To determine the proportion of women who have pregnancy terminations as private patients in Victoria who do not intend to claim a procedure fee rebate from Medicare, to compare characteristics of women who intend to submit a Medicare claim with those who do not and to compare the findings to the results from a similar study conducted in NSW in 1992.

Design, setting and participants: This was a cross-sectional observational study over a 12-week period. Women having a pregnancy termination service in eight large Victorian private clinics were invited to complete a brief written questionnaire.

Outcome measurer: The proportion of women who did not have a Medicare card or who had a Medicare card but did not intend to use it to claim from Medicare.

Results: Of the 1,329 women who responded, 13.1% either did not have a Medicare card or did not intend to use their card to claim a Medicare rebate. A further 20.7% of respondents were not sure about whether they would submit a claim. Women who intended to claim a Medicare rebate were different from women who did not according to age, language spoken at home, residency, citizenship and distance travelled to the service. These results are very similar to the findings from the 1992 NSW study.

Conclusion: Between 13.1% and 33.8% of private Victorian pregnancy terminations were estimated to not be recorded at the Health Insurance Commission. Health Insurance Commission records of Medicare rebate claims for pregnancy terminations are an incomplete and somewhat biased record of the services that are provided and are likely to have been so for some time.

An examination of psychological contracts, careerism and intention to leave

Purpose - The aim of this paper is to investigate the relationships between elements of the psychological contract (i.e., type and fulfilment) and an employee’s intention to leave (ITL) their current organisation. The role of careerism as a potential mediating and moderating variable is also explored.

Design/methodology/approach - Allied Health Professionals (N=202) completed a questionnaire containing measures of the psychological contract, careerism and ITL.

Findings - As predicted, path analyses conducted via structural equation modelling demonstrated that careerism partially mediates the relationship between contract types and ITL. These findings suggest that employees with transactional contracts are more careerist, resulting in higher ITL, while employees with relational contracts are less careerist, resulting in lower ITL. Contrary to expectation, a hierarchical multiple regression analysis revealed that careerism failed to moderate the relationship between perceived contract fulfillment and ITL. However, a strong positive association between contract fulfillment and ITL was found.

Research limitations/implications - The data were collected cross-sectionally, which limits the ability to make causal inferences.

Practical implications - Results were consistent with the proposition that contract type and fulfillment predict employee ITL. It appears that employees with relational contracts are more likely to remain with their organization on a longer-term basis, compared to employees with transactional contracts, due to differences in career motives. Organizational awareness and understanding of employee psychological contracts and career motives is needed.

Originality/value - This paper provides new theoretical and practical insights on how psychological contracts and careerism can influence Intention to leave among Allied Health Professionals.

I had gone to teach but stayed to learn: Geraldine MacKenzie at Aurukun Mission, 1925-1965

This article examines the missionary career of Geraldine MacKenzie who, with her husband Bill MacKenzie, served on the Presbyterian mission at Aurukun on the Cape York Peninsula between 1925 and 1965. It focuses primarily on MacKenzie’s own interpretation of and reflection on her experiences, as described in her memoir, Aurukun Diary. While the memoir elides some of the more controversial features of the MacKenzies’ tenure at Aurukun, it provides insights into the changing nature of missionary theology and practice on Aboriginal missions in the early twentieth century, particularly as they relate to the role of women—both missionaries and mission residents.

Sustainable Wastewater Management: Is it Possible to Regulate Micropollution in the Future by Learning from the Past? A Policy Analysis

This paper applies a policy analysis approach to the question of how to effectively regulate micropollution in a sustainable manner. Micropollution is a complex policy problem characterized by a huge number and diversity of chemical substances, as well as various entry paths into the aquatic environment. It challenges traditional water quality management by calling for new technologies in wastewater treatment and behavioral changes in industry, agriculture and civil society. In light of such challenges, the question arises as to how to regulate such a complex phenomenon to ensure water quality is maintained in the future? What can we learn from past experiences in water quality regulation? To answer these questions, policy analysis strongly focuses on the design and choice of policy instruments and the mix of such measures. In this paper, we review instruments commonly used in past water quality regulation. We evaluate their ability to respond to the characteristics of a more recent water quality problem, i.e., micropollution, in a sustainable way. This way, we develop a new framework that integrates both the problem dimension (i.e., causes and effects of a problem) as well as the sustainability dimension (e.g., long-term, cross-sectoral and multi-level) to assess which policy instruments are best suited to regulate micropollution. We thus conclude that sustainability criteria help to identify an appropriate instrument mix of end-of-pipe and source-directed measures to reduce aquatic micropollution.

Health beliefs and attitudes of HPV among Hispanic parents as predictors of intention to use the HPV vaccine

Human Papillomavirus (HPV) is the most common sexually transmitted disease in the United States. Although HPV prevalence is high in the United States, there are a limited number of research studies that focus on Hispanics, who have higher incidence rates of cervical cancer than their non-Hispanic counterparts. The HPV vaccine introduced in 2006 may offer a feasible solution to the issues surrounding high prevalence of HPV. Due to the high prevalence of HPV infection among adolescents and young adults it has been suggested that HPV vaccination begin prior to onset sexual activity and focus on non-sexually active adolescents and pre-adolescents. Consequently, it has become increasingly important to assess knowledge and awareness of HPV in order to develop effective intervention strategies. This pilot study evaluated the knowledge and health beliefs of Hispanic parents regarding HPV and the HPV vaccine using a newly developed questionnaire based on the constructs of the Health Belief Model. The sample was recruited from an ob-gyn office in El Paso, Texas. Descriptive data show that the majority of the sample was female (94.1%), Hispanic (76.5%), Catholic (64.7%), and had at least a high school education (55.9%). Chi-square analysis revealed that the following variables differed amongst parents who intended to vaccinate their child against HPV and those who did not: religion (p=0.038), perceived severity item "HPV infections are easily treated" (p=0.052), perceived benefits item "It is better to vaccinate a child against an STI before they become sexually active" (p=0.014) and perceived barriers item "The HPV vaccine may have serious side effects that could harm my child" (p=0.004). Univariate logistic regression indicated that religion (OR = 4.8, CI: 1.04, 21.8) and "The HPV vaccine may have serious side effects that could harm my child" (OR = 15.9, CI: 1.73, 145.8) were significant predictors of parental intention to vaccinate. Multivariate logistic regression, using backwards elimination, indicated that religion (OR = 7.7, CI: 1.25, 47.8) and "The HPV vaccine may have serious side effects that may harm my child" (OR = 7.6, CI: 1.15, 50.2) were the best predictive variables for parental intention to vaccinate. ^
