Aggressive Behaviour of Different Social and Demographic Groups in Post-Totalitarian Society

The project looked at aggressiveness in different age and social groups of modern post-totalitarian society, beginning with the hypotheses that the greatest risk groups are teenagers and the unemployed, and that there is a link between aggression and the level of meaningfulness of life. The groups studied comprised about 200 persons from urban areas of eastern Ukraine, including schoolchildren, students, white collar workers, self-employed persons, the unemployed and pensioners. Workers in industry were not included as this group has virtually disappeared in Ukraine at present since most enterprises have ceased to work and most workers have moved into the groups of the unemployed or self-employed. Participants were divided into age groups of 13-14, 16-17, 18-22, 24-45, 46-60 and over 60, with each group including approximately equal number of men and women. Research methods included Buss-Darky techniques, the "hand test" (E. Wagner), the "non-existent animal" technique, a Rozenzweig picture frustration study, purpose-in-life tests and an interview. The Buss-Darky test showed that schoolchildren have the highest level of aggression, followed by students. These groups have high indexes in virtually all types of aggression, including its open form. The self-employed have relatively lower indexes, although they are more likely to manifest it openly, while such open manifestations are less likely among white-collar workers, pensioners and the unemployed. The least aggressive were the unemployed and pensioners, although the latter had a relatively high level of hostility. In terms of age, aggression was shown to decrease with age, which Ms. Ivanova attributes to the still imperfect control mechanisms of teenagers and their less mature personalities. Among the younger groups girls showed a slightly higher level of aggression, although this situation was reversed among older people. The risk groups inclined to manifest open forms of aggressiveness can therefore be seen to be teenagers and students. Other tests used show aggressiveness as a feature of the current state, rather than as an inherent feature and the results obtained were somewhat different. In the interviews, all adults referred to the increased aggressiveness in society and most stated that they themselves had become more aggressive and bad-tempered. The ability of individuals to adapt to their social environment was also investigated and schoolchildren turned out to have the lowest adaptation index and the unemployed the highest. MS. Ivanova attributes that latter, rather surprising, result to the fact that the constant frustrations facing the unemployed force them to actively seek ways and means of adapting in order to survive. The final aspect considered was the possible connection between human aggressiveness and the meaningfulness of life. Here the groups with the most meaningful lives were the self-employed and pensioners. The latter result, again rather surprising, was attributed to the desire of people who have already lived the greater part of their lives to place more weight on what they have already done, in order to prove to themselves that they have not lived in vain. The hypothesis that aggressiveness is conversely related to the meaningfulness of life was only partially confirmed. In the two extreme cases (schoolchildren and pensioners) this was indeed the case, but the remaining groups did not show any such connection. From the data obtained, Ms. Ivanova concluded that life in modern post-totalitarian society does indeed foster a rise in people's aggressiveness, and this was supported by the fact that indexes of aggressiveness proved to be higher than the norm. Her original hypothesis as to the groups in society most at risk from open aggression confirmed in the case of teenagers but not of the unemployed, who had relatively low aggressiveness indexes and the highest degree of adaptation.

Socio-demographic inequalities in the diets of mid-aged Australian women

Objectives: This study reports on the distributions of food and nutrient intakes by socio-demographic factors for a large population sample of mid-aged Australian women participating in the Australian Longitudinal Study on Women's Health.
Design: This cross-sectional population-based study used the Cancer Council of Victoria food frequency questionnaires to derive estimates of food and nutrient intakes.
Setting: Nationwide community-based survey.
Subjects: A total of 10561 women aged 50-55 y, at the time of the survey in 2001.
Results: Analysis showed favourable patterns of food intake, with frequent consumption of many foods that are promoted as components of a healthy diet (eg, fresh fruit, leafy green and other vegetables, bread, cereals, milk and meat). Intakes of both foods and nutrients varied significantly across socio-demographic groups, with unmarried women, and women in 'labouring' occupations (eg, cleaner, factory worker, kitchenhand) having poorer nutrient intake.
Conclusions: Although many mid-aged women in this sample had generally healthful diets, women in certain socio-demographic groups (particularly unmarried women and those in labouring occupations) had nutrient intakes of concern. As well as helping to address the dearth of current data on dietary intakes in the Australian population, the results highlight the need for continued targeted public health strategies aimed at improving diet of women from the various socio-economic backgrounds.

Online learning environments : same place; different demographic space?

This paper presents a large scale, quantitative investigation of the impact of demographic differences on the student experience of using an online learning environment (OLE). Female respondents generally gave higher ratings than males, and gave significantly higher ratings in both importance and satisfaction to a group of OLE elements related to online interaction and community. Postgraduate respondents generally gave lower satisfaction ratings than undergraduate students, though significant differences were few. Results on the basis of mode of enrolment were mixed. The discovery of significant differences between demographic groups highlights the importance of up-to-date and on-going research-based surveys of student perceptions of the OLE. The finding that elements of the institutional OLE are not universally perceived the same way by all students groups also challenges the value of standard, one-size-fits-all institutional policies and templates relating to the use of the OLE.

Demographic differences in public attitudes towards sex offenders

Emotionally fueled public responses to news of released sex offenders have the potential to jeopardize the re-entry process, for example, hindering access to stable housing and employment opportunities. Influencing change in public attitudes towards sex offenders so that they are conducive to successful community re-entry is important in efforts to prevent recidivism. Maximizing the effectiveness of attempts to change public attitudes first requires identifying whether specific demographic groups are more prone to negative attitudes, so that attempts to change attitudes can be appropriately targeted. In the present study, 401 community members completed an online questionnaire designed to assess the affective, cognitive and behavioral dimensions of attitudes towards sex offenders. Differences in attitudes towards sex offenders based on respondent sex, age, educational attainment, occupation, parental status and familiarity with victims and perpetrators of sexual assault were investigated. Females demonstrated more-negative attitudes on affective and behavioral measures compared with males, and respondents with low levels of educational attainment demonstrated more-negative attitudes than respondents with higher levels of educational attainment on cognitive and behavioral measures; however, all groups demonstrated negative attitudes towards sex offenders to some extent. Implications for community-level interventions that promote effective re-entry, and hence reduce the likelihood of sexual reoffending are discussed.

An examination of the mediating role of salt knowledge and beliefs on the relationship between socio-demographic factors and discretionary salt use: a cross-sectional study

Background Discretionary salt use varies according to socio-demographic factors. However, it is unknown whether salt knowledge and beliefs mediate this relationship. This study examined the direct and indirect effect of socio-demographic factors on salt knowledge and discretionary salt use in a sample of 530 Australian adults.

Methods An internet based cross-sectional survey was used to collect data for this study. Participants completed an online questionnaire which assessed their salt knowledge, beliefs and salt use behaviour. Mplus was used to conduct structural equation modelling to estimate direct and indirect effects.

Results The mean age of the participants was 49.2 years, and about a third had tertiary education. Discretionary salt use was inversely related to age (r=-0.11; p<0.05), and declarative salt knowledge (knowledge of factual information) scores (r = -0.17; p<0.01), but was positively correlated with misconceptions about salt (r = 0.09; p<0.05) and beliefs about the taste of salt (r = 0.51; p<0.001). Structural equation modelling showed age, education and gender were indirectly associated with the use of discretionary salt through three mediating pathways; declarative salt knowledge, misconceptions about salt and salt taste beliefs.

Conclusions Inequalities observed between socio-demographic groups in their use of discretionary salt use can potentially be reduced through targeted salt knowledge and awareness campaigns.

The Effect of College Student Demographic Variables on Teacher Enmeshment

Interactions between students and faculty outside of class appear to be linked to greater achievement during and after college (Anaya & Cole, 2001; Hathaway, Nagda, & Gregerman, 2002). However, sometimes there can be blurred personal boundaries and a lack of autonomy in relationships or what has been labeled enmeshment. The purpose of the current pilot study was to investigate the effect of race/ethnicity, gender, year in college, and college major on faculty-student relationships and teacher enmeshment. Teacher enmeshment was measured with the Teacher Enmeshment subscale of the Separation-Individuation Test of Adolescence (SITA; Levine & Saintonge, 1993). A sample of 165 undergraduate and graduate students from education and psychology classes at a small, private liberal arts institution in the Northeast participated. No significant differences among the different demographic groups were found on the total teacher enmeshment score. However, significant differences were found among students with different majors, by gender, and by race on individual items. Implications of these findings and suggestions for future research are provided.

Maintaining your career “edge” in a global world of work

The world of work in the 21st century has been described by many as globalised (Peiperl & Jonsen, 2007; Levy, 2007; Bhagat, 2006; Czinkota & Ronkainen, 2005). Globalisation is generally understood as a greater awareness of the world as a whole; an integrated stage where the countries of the world are seen to be players on the one playing field. This notion is driven by a perception of the world as being occupied by global citizens who are affiliated not with the country in which they are born but whose loyalties lie with planet Earth. They strive to live and work with this focus foremost in their consciousness. Indeed, many of these global citizens will enjoy global careers during their lifetime whereby they work in more than one region of the world during the course of their employment. The present chapter will present a discussion on globalisation and its impact on the world of work, in particular the changes on particular demographic groups in both developed and developing economies. It will then discuss implications for workers and their careers, specifically focusing on changing relationships between workers and organisations and the need for individuals to maintain their competitive edge in the market place through an ongoing focus on relevant career management competencies.

Democratic participation in a globalised World : immigrants in Australia in the early 21st century

This study considers patterns of political participation in Australia in the early 21st Century, using recent data from the Australian Election Study. The paper reassesses how Australia fits within broader patterns of political participation and investigates major predictors of participation in Australia to see how these have or have not changed in a globalised era that has brought new challenges. Factors considered include socio-demographic variables, such as education, age, gender, birthplace and place of residence and also attitudinal orientations towards politics, such as political interest, efficacy and trust. The paper pays particular attention to those who have moved to Australia from other countries. One of the most important findings is that immigrants show little or no sign of any participatory disadvantage and indeed tend to participate more than the Australian-born in some modes of participation, such as campaign activities. The analysis also identifies a clear participatory divide within a number of socio-demographic groups in use of the internet for gaining election information.

Driver licensing experience of Korean Australians

Graduated licensing has been identified as the most promising approach to reducing the crash risk of novice drivers. However, research suggests that the effectiveness of graduated licensing appears to differ between urban and rural novice drivers and according to race or ethnicity. Extensive supervised driving practice as a learner driver is an important component of graduated licensing systems in Australia and many other countries. Earlier CARRS-Q research identified that falsification of logbooks was more common among particular demographic groups. The factors underlying this are not well understood. It is unclear whether this reflects a lack of understanding of the importance of supervised practice (given that it is not a licensing requirement in many countries of origin), or it reflects lack of access to vehicles and supervising drivers, or whether there is less respect for driver licensing requirements among some groups. It is possible that the importance of these factors may differ across ethnic groups, depending on socioeconomic factors and cultural attitudes to road safety. In an attempt to better understand these issues, this study presents some preliminary results of focus groups examining the experience of the Queensland Graduated Driver Licensing System by Korean-Australian novice drivers and their parents.

Cultural and linguistic localization of games to bridge the digital and cultural divide in indigenous populations

Localization of technology is now widely applied to the preservation and revival of the culture of indigenous peoples around the world, most commonly through the translation into indigenous languages, which has been proven to increase the adoption of technology. However, this current form of localization excludes two demographic groups, which are key to the effectiveness of localization efforts in the African context: the younger generation (under the age of thirty) with an Anglo- American cultural view who have no need or interest in their indigenous culture; and the older generation (over the age of fifty) who are very knowledgeable about their indigenous culture, but have little or no knowledge on the use of a computer. This paper presents the design of a computer game engine that can be used to provide an interface for both technology and indigenous culture learning for both generations. Four indigenous Ugandan games are analyzed and identified for their attractiveness to both generations, to both rural and urban populations, and for their propensity to develop IT skills in older generations.

Genetic and environmental influences on neuroimaging phenotypes: A meta-analytical perspective on twin imaging studies

Because brain structure and function are affected in neurological and psychiatric disorders, it is important to disentangle the sources of variation in these phenotypes. Over the past 15 years, twin studies have found evidence for both genetic and environmental influences on neuroimaging phenotypes, but considerable variation across studies makes it difficult to draw clear conclusions about the relative magnitude of these influences. Here we performed the first meta-analysis of structural MRI data from 48 studies on >1,250 twin pairs, and diffusion tensor imaging data from 10 studies on 444 twin pairs. The proportion of total variance accounted for by genes (A), shared environment (C), and unshared environment (E), was calculated by averaging A, C, and E estimates across studies from independent twin cohorts and weighting by sample size. The results indicated that additive genetic estimates were significantly different from zero for all metaanalyzed phenotypes, with the exception of fractional anisotropy (FA) of the callosal splenium, and cortical thickness (CT) of the uncus, left parahippocampal gyrus, and insula. For many phenotypes there was also a significant influence of C. We now have good estimates of heritability for many regional and lobar CT measures, in addition to the global volumes. Confidence intervals are wide and number of individuals small for many of the other phenotypes. In conclusion, while our meta-analysis shows that imaging measures are strongly influenced by genes, and that novel phenotypes such as CT measures, FA measures, and brain activation measures look especially promising, replication across independent samples and demographic groups is necessary.

Economic evaluation of the upselling prevention pilot

The aim of this report was to present findings of an economic evaluation of the UP Pilot. A decision analytic model was used to examine the monetary cost of offering each of the four interventions in the UP Pilot against success measures. The evaluation also included subgroup analysis by demographic groups to offer insights into groups that are more resistant to undertaking preventive actions, with the possibility of further research to better understand client motivation for undertaking preventive behaviour. Based on the evaluation, this report makes recommendations for further investment and implementation of the UP Pilot.
