  • Description: This chapter discusses what spirituality is and its place in education. Topics discussed are interest in spirituality, the nature of spirituality, dimensions of health, spiritual health and well being, and a model of spiritual health. Spirituality is innate, emotive, subjective, dynamic and not religion. Spiritual health and well being are reflected in the quality of relationships in four domains of human existence - people with themselves, with others, with the environment, and with a transcendent other. The model embraces the divergence of world views, beliefs and lived experiences of humanity, as expressed in the knowledge and inspirational aspects of spiritual well being in each of the domains.

  • Description: This paper reports on research which aimed to investigate relationships between meaning and purpose in life and workplace expectations. It provides an overview of the methodology and outcomes of a survey conducted at a regional university. Survey methods included the distribution of two valid and reliable instruments to all employees of that university with data analysed using SPSS procedures. Analysis of the Spiritual Health and Life-Orientation Measure (SHALOM), developed by the principal researcher, and a purpose-designed questionnaire pertaining to meaning and purpose in the workplace, provided interesting findings. Overall, participants classified as administrators, professionals, service workers or labourers reported that they feel good about themselves and their relationships with others and the environment. The relationship with a god-type figure was of lesser importance for the spiritual well-being of the majority of participants. The participants do not expect the workplace to provide a major role in their spiritual well-being. They also reported significantly high levels of feelings of turbulence at work, and trends toward high anxiety and discomfort with autocratic managerial practices characterised by a focus on profits over people. The female staff described the workplace as more friendly, warm and caring than the males. The females also reported greater work satisfaction and were less depressed in doing their job than the males. Interpretation of these results indicates that a somewhat anxious and turbulent work place environment prevails. The personal impact of this unrest appears to be mediated by the support of families and friends of employees. The notion that workplace feelings which are negative (eg., anxiety) emanate from administrative practices, while those which are positive are a function of collegial behaviours, merits further exploration.

  • Description: The complexity of rural practice in rural and remote communities means that higher order skills are required by rural social workers. In 1991, the University of Ballarat in Victoria (Australia) began teaching a course to prepare students for work in rural social welfare. The course was developed partly to meet industry needs, as local agencies were unable to attract qualified staff. While generic skills, such as counseling and group work, are taught, they are taught with emphasis on particular issues likely to occur in rural settings. Contextual issues include the role of the practitioner as a professional and a community member, confidentiality and privacy, and working within and between complex social networks. Existing courses of social work and welfare address rural practice in a peripheral fashion, whereas rural practice is thoroughly integrated into all elements of this course: course philosophy, curriculum design, teaching strategies, and assessment. The course's philosophical approach emphasizes community development principles of engagement and empowerment within communities. A brief framework of the course and evaluations completed by staff and students are provided. (Contains 15 references.) (TD)

  • Description: Historical evidence of early salinity, vegetation and landuse changes, and pedological studies have been used in formulating a new model for salinity processes acting on the Dundas Tableland in southwestern Victoria. Contrary to previous assumptions, salinity in this area was a feature of the pre-European landscape and was noted in the earliest surveys and journals. Analysis of historical records show an initial post-settlement increase in the tree numbers, followed by a rapid decline much later than previously assumed. Accumulation of salts in the regolith may be attributed to marine incursions during the Miocene and Pliocene, the extensive weathering to develop a deep regolith, and wind-blown and cyclic salt accumulation. A trend analysis of historical streamflow and bore hydrograph records does not indicate rising groundwater levels. The pedological features of duplex and sodic soil profiles support a history of prolonged seasonal waterlogging. A model with seasonal lateral flow of water through the upper regolith can better account for the spread of salinity than the rising groundwater hypothesis. By control of waterlogging, land managers could improve soil structure, enhance root growth and soil water use, as well as inhibit the spread of salinity.

The effects of a problem-solving program on adolescent's problem-solving skills

  • Description: The purpose of the study was to examine the effect of a group training program, based on cognitive behavioural theory and techniques, on the problem-solving skills of adolescents. Evidence of a link between suicidal ideation (engaging in suicidal thinking) and reported deficits in social problem-solving or coping competence levels in adolescents is an area of investigation that offers some hope for suicide primary prevention programs. The study tried to determine if teaching social problem solving skills in a school would better equip adolescents with coping with problematic situations. The work of Hawton (1997) Hawton and Kirk (1989), Lerner and Clum (1990) and McLeavey, Daly, Ludgate and Murray (1994) formed the basis of the training program design. The emphasis was on general problem-solving skills rather on a participant’s specific current problems. Included was training in listening skills, assistance in developing problem-solving skills rather on a participant’s specific current problems. Included was training in listening skills, assistance in developing appropriate problem-solving behaviours and role simulation through the use of structured video case scenarios. Seventy four male and female year 10 secondary school students were subjects in the study. They were randomly divided into two, approximately equal, groups. Thirty six subjects established the control group and the remaining thirty eight constituted the experimental group. The findings indicated that students exposed to the problem solving training program did not have significantly higher problem-solving ability, as measured by the Problem Solving Inventory (PSI) than those who were not exposed to the training. However, females in the experimental group were significantly more likely to make conscious decisions about when they would approach or avoid a problem when compared to control group females. It is suggested that the adaptation of training, designed for suicidal clients, needs to be explored further for application to Year 10 students in the general population. More research is needed into ways to provide school based preventative training programs that will assist in the development of coping skills.

  • Description: This study investigated the effectiveness of an Internet-based intervention for people with panic disorder. Twenty-two participants met criteria for panic disorder and were randomly assigned to either the treatment or a self-monitoring control condition. The study took place over 3 weeks and consisted of one week of self-monitoring prior to the intervention group accessing the program for one week, followed by one week of post-intervention assessment. Participants were assessed on measures pertaining to panic, negative affect, body vigilance, anxiety sensitivity and self-efficacy in managing panic. The treatment condition was associated with significant reductions in all variables except anxiety sensitivity and depressive affect. This type of intervention for people with fearful panic attacks holds promise as an efficacious and economical method for treating spontaneous panic.

  • Description: In this paper global optimisation-based techniques are studied in order to increase the accuracy of medical diagnosis and prognosis with FNA image data from the Wisconsin Diagnostic and Prognostic Breast Cancer databases. First we discuss the problem of determining the most informative features for the classification of cancerous cases in the databases under consideration. Then we apply a technique based on convex and global optimisation to breast cancer diagnosis. It allows the classification of benign cases and malignant ones and the subsequent diagnosis of patients with very high accuracy. The third application of this technique is a method that calculates centres of clusters to predict when breast cancer is likely to recur in patients for which cancer has been removed. The technique achieves higher accuracy with these databases than reported elsewhere in the literature.

  • Description: It is central to the control of manipulators to calculate the set/sets of joint-displacements which correspond to a given spatial pose (position and orientation) of the end-effector. This problem, which is referred to as the inverse position problem, represents one of the most difficult mathematical challenges in the field of robotics, particularly when performed for calibrated robots (or robots with general structures). In such cases, closed form solutions are too impractical to implement and iterative solutions suffer from numerical singularities. In the present work a procedure is introduced to obtain multiple inverse position solutions for serial robotic structures. For calibrated robots, the procedure involves a simple iterative technique designed to ensure fast convergence and eliminate the occurrence of singularity. However, inverse position solutions for spherical-wrist manipulators will be obtained in a straight-forward non-iterative fashion. A published kinematic notation, referred to as the phi -model, was used to develop the system equations.

  • Description: The performance of a landfill clay liner is generally evaluated using the hydraulic conductivity values obtained from laboratory tests during the design stage. Laboratory tests for the determination of hydraulic conductivity are frequently carried out either using water as the permeating liquid or some times using a chemical permeant to represent leachate. However, any investigations incorporating time as a variable in analysing the effects of leachate on various other soil properties that can influence the hydraulic conductivity are very limited. This study is aimed at investigating the effects of landfill leachate on the performance of a compacted basaltic clay soil, over a period of time. For this purpose, a typical Melbourne basaltic clay with varying percentages of montmorillonite clay was selected and a synthetic leachate was developed based on the composition of typical municipal waste landfill leachate reported in the literature. The clay -leachate interactions were allowed take place under controlled anaerobic laboratory conditions. Samples were then tested at different time periods to identify possible variations of engineering properties such as volume change, consistency and grain size distribution due to the effect ofleachate over time, since variation of these soil properties can affect the hydraulic conductivity of a clay soil. The analysis of test results suggests that the behaviour of a basaltic clay liner could be significantly affected by clay leachate interactions over time, due to possible alterations to physical and mineralogical properties of the clay.

  • Description: Accurate use of robots in an off-line programming mode is only possible through a proper calibration procedure. In this procedure, the end-effector is made to move along a set of known spatial poses where the positional errors are to be measured and employed in mathematical models. The models are subsequently solved for the manipulator dimensions (geometric parameters) using suitable regression techniques. Calibration is usually performed using either aggregate or independent-axis models. While the aggregate models result in all the system parameters being worked out simultaneously, the independent-axis models are meant to work out the geometric particulars of each joint-axis individually. In the present work, the independent-axis technique is used for the analysis with new mathematical models proposed to overcome the drawbacks of the existing methods. Moreover, the techniques employed here result in the prediction of transmission error functions and the modelling of the joint motion dependencies. This is a new concept in the field of robot calibration. Finally, the models proposed have been used to calibrate an ASEA IRB/L6 robot and the results are reported at the end of the paper.
