Who gets the cats...you or me? Analyzing contact and residence issues regarding pets upon divorce or separation

Mills and Akers outline the statistical incidence of pet ownership and people's need for domestic pets, discuss ownership or property rights in domestic pets, outline the criteria used by the courts when ruling on implied contact and residence rights regarding domestic pets upon the irretrievable breakdown between the "owners" of the particular pets, and highlight both the shortcomings in the existing law and possible means of overcoming those shortcomings.

Identifying Heel Contact and Toe-Off Using Forceplate Thresholds With a Range of Digital-Filter Cutoff Frequencies

Analysis of human gait requires accurate measurement of foot-ground contact, often determined using either foot-ground reaction force thresholds or kinematic data. This study examined the differences in calculating event times across five vertical force thresholds and validated a vertical acceleration-based algorithm as a measure of heel contact and toe-off.

Direct current electric potential in an anisotropic half-space with vertical contact containing a conductive 3D body

Detailed studies of anomalous conductors in otherwise homogeneous media have been modelled. Vertical contacts form common geometries in galvanic studies when describing geological formations with different electrical conductivities on either side. However, previous studies of vertical discontinuities have been mainly concerned with isotropic environments. In this paper, we deal with the effect on the electric potentials, such as mise-`a-la-masse anomalies, due to a conductor near a vertical contact between two anisotropic regions. We also demonstrate the interactive effects when the conductive body is placed across the vertical contact. This problem is normally very difficult to solve by the traditional numerical methods. The integral equations for the electric potential in anisotropic half-spaces are established. Green’s function is obtained using the reflection and transmission image method in which five images are needed to fit the boundary conditions on the vertical interface and the air-earth surface. The effects of the anisotropy of the environments and the conductive body on the electric potential are illustrated with the aid of several numerical examples.

Application of bending under tension test to determine the effect of tool radius and the contact pressure on the coefficient of friction in sheet metal forming

To quantify the frictional behaviour in sheet forming operations, several laboratory experiments which simulate the real forming conditions are performed. The Bending Under Tension Test is one such experiment which is often used to represent the frictional flow of sheet material around a die or a punch radius. Different mathematical representations are used to determine the coefficient of friction in the Bending Under Tension Test. In general the change in the strip thickness in passing over the die radius is neglected and the radius of curvature to thickness ratio is assumed to be constant in these equations. However, the effect of roller radius, sheet thickness and the surface pressure are also omitted in some of these equations. This work quantitatively determined the effect of roller radius and the tooling pressure on the coefficient of friction. The Bending Under Tension Test was performed using rollers with different radii and also lubricants with different properties. The tool radii were found to have a direct influence in the contact pressure. The effect of roller radius on friction was considerable and it was observed that there is a clear relationship between the contact pressure and the coefficient of friction.

Healthy nature healthy people: 'contact with nature' as an upstream health promotion intervention for populations

Whilst urban-dwelling individuals who seek out parks and gardens appear to intuitively understand the personal health and well-being benefits arising from `contact with nature', public health strategies are yet to maximize the untapped resource nature provides, including the benefits of nature contact as an upstream health promotion intervention for populations. This paper presents a summary of empirical, theoretical and anecdotal evidence drawn from a literature review of the human health benefits of contact with nature. Initial findings indicate that nature plays a vital role in human health and well-being, and that parks and nature reserves play a significant role by providing access to nature for individuals. Implications suggest contact with nature may provide an effective population-wide strategy in prevention of mental ill health, with potential application for sub-populations, communities and individuals at higher risk of ill health. Recommendations include further investigation of `contact with nature' in population health, and examination of the benefits of nature-based interventions. To maximize use of `contact with nature' in the health promotion of populations, collaborative strategies between researchers and primary health, social services, urban planning and environmental management sectors are required. This approach offers not only an augmentation of existing health promotion and prevention activities, but provides the basis for a socio-ecological approach to public health that incorporates environmental sustainability.

Health and well-being naturally: 'contact with nature' in health promotion for targeted individuals, communities and populations

Issue addressed: The increase in mental health disorders worldwide makes it important to recognise health promotion interventions that are effective, accessible and affordable. Although natural spaces are coming to be recognised as health-promoting settings for general populations, little is understood about the use of nature contact in treatment and care for individuals experiencing ill-health.

Methods: This paper provides a summary of key research findings and presents a case study examining the self reported health and well-being benefits of nature contact for a small clinical sample. The 'Spectrum of Interventions for Mental Health Problems and Mental Disorders' provides a conceptual framework for ordering current and future information relating to nature-based interventions.

Results: Evidence demonstrates that separately, physical activity, social connection, and contact with nature enhance human health and well-being. The case example illustrates how 'active', 'social' and 'adventurous' contact with nature may be combined within a treatment intervention to protect and enhance the health of individuals experiencing chronic mental, emotional and physical health difficulties.

Conclusions: 'Contact with nature' constitutes a health promotion strategy with potential application in prevention, early intervention, treatment and care. Recommendations include further research to investigate the benefits of nature contact within existing interventions, and the impacts of 'active' and 'social' nature contact within tailored interventions for targeted individuals and communities.

Children's mental health and wellbeing and hands-on contact with nature

Research on the health and wellbeing benefits of contact with animals and plants indicates the natural environment may have significant positive psychological and physiological effects on human health and wellbeing. In terms of children, studies have demonstrated that children function better cognitively and emotionally in 'green' environments and have more creative play. In Australia as well as internationally, many schools appear to be incorporating nature-based activities into their curricula, mostly via sustainability education. Although these programs appear to be successful, few have been evaluated, particularly in terms of the potential benefits to health and wellbeing. This paper reports on a pilot survey investigating the mental health benefits of contact with nature for primary school children in Melbourne, Australia. A survey of principals and teachers was conducted in urban primary schools within a 20km radius of Melbourne. As well as gathering data on the types and extent of environmental and other nature-based activities in the sample schools, items addressing the perceptions of principals and teachers of the potential effects of these activities on children's mental health and wellbeing were also included. Despite a lower than expected response rate, some interesting findings emerged. Although preliminary, results indicate that participants' perceptions of the benefits to mental health and wellbeing from participation in hands-on nature based activities at their school are positive and encompass many aspects of mental health.

Contact pressure and wear in sheet metal forming - an FEM analysis

Wear is the principal cause of tool failure in most sheet metal forming processes. It is well known that the contact pressure between the blank and the tool has a large influence on the wear of the tool, and hence the tool life. This investigation utilises the finite element method to analyse the contact pressure distribution over the die radius for a particular deep drawing process. Furthermore, the evolution of the predicted contact pressure distribution throughout the entire stroke of the punch is also examined. It was found that the majority of the process shows a steady state pressure distribution, with two characteristic peaks over the die radius, at the beginning and end of the sheet contact area. Interestingly, the initial transient contact pressure response showed extremely high localised peak pressures; more than twice that of the steady state peaks. Results are compared to wear reported in the literature, during similar experimental deep drawing processes. Finally, the significance and effect of the results on wear and wear-testing techniques are discussed.

Modeling of contact pressure in sheet metal forming

For a given sheet metal forming process, an accurate determination of the contact pressure distribution experienced is an essential step towards the estimation of tool life. This investigation utilizes finite element (FE) analysis to determine the evolution and distribution of contact pressure over the die radius, throughout the duration of a channel forming process. It was found that a typical two-peak steady-state contact pressure response exists for the majority of the process. However, this was preceded by a transient  response, which produced extremely large and localized contact pressures. Notably, it was found that the peak transient contact pressure was more than double the steady-state peak. These contact pressure results may have a significant influence on the tool wear response and therefore impact current wear testing and prediction techniques. Hence, an investigation into the validity of the predicted contact pressure was conducted.

Healthy parks, healthy people : the health benefits of contact with nature in a park context : a review of current literature

This review identifies significant research that has not previously been compiled. It will provide key information for decision making by park managers, forming the basis of a program of future research to overcome the limited knowledge in this area. It is part of stage two of this project, funded by the International Park Strategic Partners Group. It builds on an earlier review (completed early in 2002 with funding provided by Parks Victoria) by addressing the health and wellbeing benefits of contact with nature in a parks context, at an individual and community level.

Self-representations of international women postgraduate students in the global university 'Contact Zone'

This article explores some aspects of the role of race and gender in shaping women postgraduate students' experience of intercultural study. It focuses on various social and cultural aspects of their sojourn. These were suggested by data from two small pilot research projects investigating the experiences of two cohorts of international women postgraduate students, the one studying in an Australian university and the other, a Canadian. The authors focus particularly on the intersections between the students' representation of themselves as women and the way they see themselves represented by their host cultures. In other words, they are interested in the students' understandings of themselves as 'other', and how this impacts on their representations of 'self'. The authors suggest that these representations reflect a process of negotiation of identity that occurs in what they call the globalising university 'contact zone'. The concept of contact zones derives from post-colonial theory. A further goal of this article, then, is to examine how such data appear when viewed from a post-colonial perspective.

Hyperstereopsis in helmet-mounted NVDs : time to contact estimation

The side mounting of the night-vision sensors on some helmet-mounted systems creates a situation of hyperstereopsis in which the binocular cues available to the operator are exaggerated such that distances around the point of fixation are increased. For a moving surface approaching the observer, the increased apparent distance created by hyperstereopsis should result in greater apparent speed of approach towards the surface and so an operator will have the impression they have reached the surface before contact actually occurs. We simulated motion towards a surface with hyperstereopsis and compared judgements of time to contact with that under normal stereopsis as well as under binocular viewing without stereopsis. We simulated approach of a large, random-field textured and found that time to contact estimates were shorter under the hyperstereoscopic condition than those under normal stereo and no stereo, indicating that hyperstereopsis may cause observers to underestimate time to contact leading operators to undershoot the ground plane when landing.
