Attitudes of Australian information system managers against online attackers

Examines the attitudes of Australian IS/IT managers to the concept of cyber-vigilantism. Also, it explores the policies and procedures which have been set in place by various organisations to cope with concerted attacks on their systems. It finds that although a majority of managers do approve of the concept of “striking back”, only a minority are prepared for this eventuality. There appears to be complacency about the threats posed by organised, offensive attackers.

Middle Permian brachiopods from the Dongujimqinqi area, Inner Mongolia, China

A small collection of brachiopods is described from the lower Middle Permian Yanchibeishan Formation of the Dongujimqinqi area, eastern Inner Mongolia, China. This fauna consists of the following four species: Kochiproductus sp., Linoproductus simensis (Tschernyschew), Rhynchopora inconstantis Lee and Gu and Licharewia grewingki (Netschajew). The Dongujimqinqi fauna exhibits a strong Boreal-type aspect and suggests an early Middle Permian in age.

Perioperative managers: role stressors and strategies for coping

This qualitative study explored the role stressors experienced by perioperative nurse managers, and identified resources and strategies they used in order to cope with the multiple demands upon their role. Grounded Theory methodology was used to inform the inquiry through interviews with the participants and thematic analysis of the data. The perioperative nurse managers who participated in the study indicated that the major stressors they experienced were related to managing their staff. Stress was reduced through the use of hospital resources and peer support, referring to post management education and information obtained from attending conferences. In addition, they used team building strategies, balanced priorities and engaged in social activities. These findings will assist directors of nursing and other nursing leaders in formulating the direction of appropriate support and structure for the development perioperative nurse managers.

A biogeographically mixed late Guadalupian (late Middle Permian) brachiopod fauna from an exotic limestone block at Xiukang in Lhaze county, Tibet

A total of 17 brachiopod species belonging to 15 genera are recorded from a limestone block of about 3×4 km2 in the Indus–Tsangbo suture zone at Xiukang in Lhaze County of Tibet. The brachiopod fauna generally indicates a Late Guadalupian age (late Wordian–Capitanian, late Middle Permian) based on its association with the Timorites-bearing ammonoid fauna and the presence of the brachiopod Urushtenoidea crenulata. Palaeobiogeographically, the fauna exhibits transitional/mixed characters between the warm-water Cathaysian and cold to temperate Gondwanan faunas and may have developed on a carbonate build-up or seamount on the oceanic crust.

Stability of body mass index in Australian children: a prospective cohort study across the middle childhood years

Objective: To investigate the prevalence and incidence of overweight and obesity, the frequency of overweight resolution and the influence of parental adiposity during middle childhood.

Design: As part of a prospective cohort study, height and weight were measured in 1997 and 2000/2001. Children were classified as non-overweight, overweight or obese based on standard international definitions. Body mass index (BMI) was transformed into age- and gender-specific Z-scores employing the LMS method and 2000 growth chart data of the Centers for Disease Control and Prevention. Parents self-reported height and weight, and were classified as underweight, healthy weight, overweight or obese based on World Health Organization definitions.

Setting: Primary schools in Victoria, Australia.

Subjects: In total, 1438 children aged 5–10 years at baseline.

Results: The prevalence of overweight and obesity increased between baseline (15.0 and 4.3%, respectively) and follow-up (19.7 and 4.8%, respectively; P < 0.001 for increase in overweight and obesity combined). There were 140 incident cases of overweight (9.7% of the cohort) and 24 of obesity (1.7% of the cohort); only 3.8% of the cohort (19.8% of overweight/obese children) resolved to a healthy weight. The stability of child adiposity as measured by BMI category (84.8% remained in the same category) and BMI Z-score (r = 0.84; mean change = −0.05) was extremely high. Mean change in BMI Z-score decreased with age (linear trend β = 0.03, 95% confidence interval 0.01–0.05). The influence of parental adiposity largely disappeared when children's baseline BMI was adjusted for.

Conclusions: During middle childhood, the incidence of overweight/obesity exceeds the proportion of children resolving to non-overweight. However, for most children adiposity remains stable, and stability appears to increase with age. Prevention strategies targeting children in early childhood are required.

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.

Developing better public policy to motivate responsible environmental behavior - an examination of managers' attitudes and perceptions towards controlling introduced species

This paper examines the application of public policy, including social marketing, to programs designed to control an environmentally harmful introduced species in Australia. Managers involved in dealing with the issue identify a range of factors that contribute to the lack of success of existing control programs. The results suggest that there needs to be a broad-based integrated program that incorporates changes in stakeholders' attitudes as well as governmental resources and support for implementation of relevant initiatives.

Fusulinoideans from the early Midian (late Middle Permian) Metadoliolina dutkevitchi-Monodiexodina sutchanica Zone of the Senkina Shapka section, South Primorye, Far East Russia.

Fusulinoideans from the Metadoliolina dutkevitchi-Monodiexodina sutchanica Zone of the lower part of the Chandalaz Formation in the Senkina Shapka section in South Primorye, Far East Russia, are described. The fusulinoidean zone is assigned to the early Midian (=Capitanian: late Middle Permian) based mainly on the morphologie and biostratigraphic characteristics of Metadoliolina dutkevitchi. Previously, a Midian age has been established for the Metadoliolina dutkevitchi-Monodiexodina sutchanica Zone by the coexistence of Lepidolina species. However, the occurrence of Lepidolina with the two zonal species in this area has not been verified by the illustration of Lepidolina specimens. We examined a fusulinoidean-bearing sample from the Metadoliolina dutkevitchi-Monodiexodina sutchanica Zone, and three fusulinoidean species, Monodiexodina sutchanica, Pseudofusulina sp. and Metadoliolina dutkevitchi, are de-scribed and illustrated.

Earthquake-controlled event deposits and its tectonic significance from the Middle Permian Wandrawandian Siltstone in the Sydney Basin, Australia

The Sydney-Bowen basin in eastern Australia is an elongate back arc-converted foreland basin system situated between the Lachlan Fold Belt in the west and the New England Fold Belt in the east. The Middle Permian Wandrawandian Siltstone at Warden Head near Ulladulla in the southern Sydney Basin is dominated by fossiliferous siltstone and mudstone, with a large amount of dropstones and minor pebbly sandstone beds. Two general types of deposits are recognized from the siltstone unit in view of the timing and mechanism of formation. One is represented by the primary deposits from offshore to subtidal environments with abundant dropstones of glacial marine origin. The second type is distinguished by secondary, soft-sediment deformational deposits and structures, and comprises three layers of mudstone dykes of seismic origin. In the latter type, metre scale, laterally extensive syn-depositional slump deformation structures occur in the middle part of the Wandrawandian Siltstone. The deformation structures vary in morphol-ogy and pattern, including large-scale complex-type folds, flexural stratification, concave-up structures, faulting of small displacements accompanied by folding and brecciation. The slumps and associated syn-sedimentary structures are attributed to penecontemporaneous deformations of soft sediments (mostly silty mud) formed as a result of mass movement of unconsolidated and/or semi-consolidated substrate following an earthquake event. The occurrence of the earthquake event deposits supports the current view that the Sydney Basin was located in a back-arc setting near the New England magmatic arc on an active continental margin during the Middle Permian.

Advanced manufacturing technology adoption - the German experience

The decision process that organisations utilise when evaluating technology investment opportunities is a complex and even political process; however, the correct decision can provide the organisation with considerable operational and competitive benefits. The research presented in this paper presents the findings of a postal survey of the benefits provided by technology investments to large German manufacturers. It was found that only where middle management generated the idea for the advanced manufacturing technology (AMT) investment was success in that investment significantly more likely. Respondents who established a project team to plan the technology proposal, regardless of the department which generated the ideas for technology investment, were not significantly associated with a greater likelihood for success.

The respondents typically took between 3 and 12 months before making the final decision to invest, irrespective of the department generating the idea for the AMT, and a further 6 months to implement the AMT. Respondents who utilised a discounted cashflow analysis took significantly longer to make the final decision to invest. The greatest number of manufacturing outcomes of significantly higher importance was identified for respondents where Engineering, IT or R&D generated the AMT ideas. It was also determined that the respondents most frequently considered AMT investments in computer hardware or software and technical training for process workers to be necessary at the time of considering the investment. Middle management were found to be significantly more concerned than managers on other levels about opposition of workers to the AMT, while the process workers were significantly more concerned about interruptions to the process during installation.

A ring-based architectural model for middle agents in agent-based system

In agent-based systems, the performance of middle agents not only relies on the matchmaking algorithms employed by them, but also the architecture that organizes them with suitable organizational structure and coordination mechanism. In this paper, we contribute a framework and develop a couple of middle agents with logical ring organizational structure to match requester agents with service provider agents. The middle agent is of the features of proliferation and self-cancellation according to the sensory input from its environment. The token-based coordination mechanism of middle agents is designed. Two kinds of middle agents, namely, host and duplicate, are designed for promoting the scalability and robustness of agent-based systems. We demonstrate the potentials of the architecture by case study.

Is there a need for cyberethics in the middle school curriculum

This research in progress is a qualitative and quantitative case study that is exploring the need for the integration of cyberethics into the curriculum for the middle school years 6 through 8. The broader research question in the study investigates: ‘Is there a problem with how school students in the middle years use the Internet in and out of school?’ The study has been exploring the level of understanding the group of students have of ethical behaviour on the Internet. This research helps identify areas where an understanding of cyberethics will increase students’ current and future understanding in the use of the Internet and their interaction with other aspects of the Internet and its environment. If a student encounters unsafe behaviour on the Internet, the student will be able to behave and act appropriately. The research is also investigating teachers and parents perceptions of the evidence of problems associated with their students/children’s access to the Internet.

This area was chosen for research because of the significant impact computers have had in education in the last decade. Since the advent of personal computers and networking the Education Departments in many developed nations have taken the opportunity to promote the technology’s educational benefits. There have been several studies on the educational value of computers in schools and the research thus far describes some of the ethical changes that have emerged as a result of the technology as well as the benefits and shortcomings of the use of this technology within the Australian environment as compared to its usage in other Western nations, namely the U.S. and U.K.

Identifying the problems in the use of the Internet by middle school students is a part of this investigation and it will make recommendations with regard to the integration of cyberethics into the middle school curriculum. This approach will help prompt students, teachers and parents to re-examine their decision framework with regard to Internet usage and hence move them to reflect and consider the use of the technology ethically. Further the research is examining students’, parents’ and teachers’ need for the introduction of cyberethics into the curriculum. The case study is drawing data from individual surveys of parents, teachers and students. The questionnaires consist of relevant scenarios so that it may identify the general understanding and use of the Internet by students, teachers and parents.

During the study, any modification to the curriculum for the integration of cyberethics is to be identified and these findings should be of interest to the wider educational community in Australia and New Zealand. The questions raised in this research may affect teacher education and help demonstrate the importance of the parents’ role in their children’s Internet usage. The research will cover current issues of cyberethics and its effects on middle school students.
