Attitudes towards and perception of gambling among secondary school students in a developing country
Chinyere Mirian Aguocha Chukwuma B. Duru Emeka Chinwuba Nwefoh Appolos Chidi Ndukuba Kennedy U. Amadi Emmanuel Omamurhomu Olose 《International Gambling Studies》2013,13(3):532-544
ABSTRACTGambling is common in Nigeria and over the years has gained wide acceptability among the populace. Improved technology and legalization of gambling have led to increased gambling opportunities among young people. The aim of this study is to determine the attitude towards and perception of gambling among a sample of secondary school students in South East Nigeria. A total of 507 male students from three male-only urban Secondary Schools in Owerri, Imo State participated in the study. Multistage sampling technique was used in sample selection. Data was collected using a self-administered socio-demographic questionnaire and the 9 Item Attitude Towards Gambling Scale. Results showed an overall negative perception of gambling. Majority of the respondents (82.8%) perceived gambling as a risky activity while few (27.3%) perceived it as a good way of earning an income quickly. More than half of the respondents (52.7%) believed that gambling yields a high return. There was a significant association between parental gambling and positive attitude towards gambling (X = 6.27, p = 0.04). Thus, preventive strategies targeted towards changing gambling attitudes in parents may serve a dual role of changing attitudes and perception of gambling in their offspring. 相似文献

The issue of managing culture is of key importance within management theory and practice. A number of extant studies have found that attempts to 'manage' culture frequently degenerate into the enforcement of espoused behaviours. The objective of this paper is to provide empirical evidence and discussion of the consequences of management attempts to change culture. The paper reviews existing theory pertaining to organizational culture change and presents the desire to control as the rationale for management attempts to modify culture. After a brief discussion of the research design and methodology employed, the findings of a single case study are presented. The findings suggest that within the case study organization, a recent change initiative had resulted in changes to material manifestations, behaviours and in some cases values. However, it is noted that modifications to values could be the result of 'instrumental value compliance'. The paper culminates with conclusions, implications and suggestions for further research. 相似文献

We examined the perceptual discrepancy profiles between self‐ and peers, and self‐ and teacher evaluations of adolescents’ social competence (SC) and the interrelations of these profiles with self‐reported depressive symptoms. The participants were 390 Finnish lower secondary school pupils. Latent profile analysis revealed five classes of discrepancy profiles; adolescents with congruent perceptions, quite congruent perceptions, and positively discrepant perceptions of SC reported lower scores of depressive symptoms, whereas those with negatively and extremely positively discrepant perceptions of SC reported the highest scores of depressive symptoms. The larger the discrepancy between self‐ and others’ evaluations of SC were, the more depressive symptoms were reported. The results indicate that interventions designed to mitigate depression need to be tailored to individual needs. 相似文献

The Northern Finland Birth Cohort 1986 (N = 8,061) was used to investigated the joint associations of physical activity and sedentary behavior with academic achievement. Logistic regression analysis was used to evaluate how classes formed by latent class analysis (LCA) according to overall physical activity, sports club membership, viewing TV, using a computer, reading books and magazines, other sedentary activities, and sleep were associated with grade‐point average. When adjusted for gender, self‐rated health, and mother's education, physically active adolescents and generally active adolescents were about twice as likely to have high grade‐point average compared with sedentary TV viewers. 相似文献

This paper contributes to the debate on the limited efficacy of civil society in Africa. It examines the complex interface between notions of civil society and citizenship within the context of the postcolonial state in Africa. It argues that the bifurcated character of citizenship is implicated in the inefficacy of civil society. This is underlined by the limited achievements in social citizenship, aggravated by the economic crisis and neoliberal reforms of the 1980s and 1990s as well as the politics of regime sustenance. Political disengagement, drain on the moral content of public life and diminished collective orientation of citizens, aggravated conflicts within society, thereby, promoting a democratisation of disempowerment and a disorganised civil society. 相似文献

Research on the relationship between casinos and crime has yielded mixed conclusions. Some authors argue that casinos are
crime attractors and provide fertile grounds for disorder in the surrounding communities. Others claim that the impact of
casinos on the crime problem has been over-stated and that casinos in themselves are not crime generators. Relying on calls
for service and incidents known to the police, this research reveals the specific spatial and temporal characteristics of
all criminal and disorderly behaviors around casino venues.

The power of randomized controlled clinical trials to demonstrate the efficacy of a drug compared with a control group depends not just on how efficacious the drug is, but also on the variation in patients' outcomes. Adjusting for prognostic covariates during trial analysis can reduce this variation. For this reason, the primary statistical analysis of a clinical trial is often based on regression models that besides terms for treatment and some further terms (e.g., stratification factors used in the randomization scheme of the trial) also includes a baseline (pre-treatment) assessment of the primary outcome. We suggest to include a “super-covariate”—that is, a patient-specific prediction of the control group outcome—as a further covariate (but not as an offset). We train a prognostic model or ensembles of such models on the individual patient (or aggregate) data of other studies in similar patients, but not the new trial under analysis. This has the potential to use historical data to increase the power of clinical trials and avoids the concern of type I error inflation with Bayesian approaches, but in contrast to them has a greater benefit for larger sample sizes. It is important for prognostic models behind “super-covariates” to generalize well across different patient populations in order to similarly reduce unexplained variability whether the trial(s) to develop the model are identical to the new trial or not. In an example in neovascular age-related macular degeneration we saw efficiency gains from the use of a “super-covariate”. 相似文献

This paper deals with the convergence of the expected improvement algorithm, a popular global optimization algorithm based on a Gaussian process model of the function to be optimized. The first result is that under some mild hypotheses on the covariance function k of the Gaussian process, the expected improvement algorithm produces a dense sequence of evaluation points in the search domain, when the function to be optimized is in the reproducing kernel Hilbert space generated by k . The second result states that the density property also holds for P-almost all continuous functions, where P is the (prior) probability distribution induced by the Gaussian process. 相似文献
