Natah and telajakan : the role and identity in indigenous villages

There are many Indigenous villages scattered across Bali Island. Most of these villages are located surrounding a mountain so that an Indigenous village in Bali is called 'Bali Aga' or 'Bali Kuna', which means "Mountain Balinese·. Bali has unique Indigenous villages still possessing traditional village patterns in harmony with their natural environment. Natah and telajakan are an integral part of traditional housing patterns in these villages. Both are often forgotten about in contemporary housing developments in Bali, because most people in the Denpasar want to construct their building with a modern style but these do not have an eco-friendly atmosphere.Natah is the open space in the centre of a compound of Balinese traditional buildings. Natah functions as a place for traditional ceremonies; as a centre of building orientation; and, as well as ecological function. Research into natah has demonstrated that the more extensive the natah and the more luxuriant its plants the greater the reductions of wind speed and humidity modification in traditional housing (Primayatna, 2010). This means that the natah direcUy influences a better quality of living in the traditional housing. Telajakan is an outdoor open space pattern of traditional housing which is located between traditional fencing (penyengker) and drainage lines (jelinjingan), which is planted for spiritual and economic functions. Natah and telajakan are largely integral components of Balinese Indigenous villages. Most well-known Indigenous villages in Bali still retain their natural linear sequences of natah and telajakan such as Penglipuran Village, Tenganan Village, etc.The paper examines the role of natah and telajakan as part of Indigenous Balinese housing traditional patterns which serves not only aesthetic functions, but economic functions, health and ecological aspects, and informs the identity of Indigenous villages in Bali. This paper focuses on how both natah and telajakan values and patterns can be adopted for future lifestyles and development in Bali.

South west Victoria 2012-2050 : are the settlements sustainable?

Over the past few decades coastal cities around the world have grown at an incredible rate. With this growth have come major challenges relating to land use planning, social relationships, economic development, bio diversity and the ecological footprint. The following paper selects three regional coastal towns (Warrnambool, Portland and Port Fairy) situated in the Australian state of Victoria, and addresses the issues of: increasing population and population density, open space requirements, residential density issues, public transport coverage, employment and employment density, a shifting economic climate, environment and climate change, water quality issues and building energy consumption with subsequent C02 emissions. Through a series of simulations the nine issues for each of the three cities will be examined from 2012 through to 2030. The goal is to highlight the current and simulated future impacts of the selected issues and propose solutions that could mitigate those impacts.

Bark in the park: a review of domestic dogs in parks

The presence of domestic dogs Canis familiaris in public open spaces is increasingly controversial. In our review of the literature, we located 133 publications of various types (papers, reports etc.) that examine some aspect of dogs in parks and open spaces (50 % focussed solely on dogs). There has been an exponential growth in the cumulative number of articles (R (2) = 0.96; 82 % published since 1997); almost all pertain to temperate latitudes (97 %) and most to the northern hemisphere (62 %). Most articles focus on impacts on wildlife (51 %), zoonotic diseases (17 %), and people's perceptions regarding dogs (12 %). Articles mostly describe problems associated with dogs, while reports of low compliance with dog regulations are common. We outline six major findings regarding dogs in parks: (1) there is a paucity of information on dogs in parks, particularly in relation to their interactions with wildlife and regarding their management; (2) published studies are mainly restricted to a handful of locations in developed countries; (3) sectors of societies hold different views over the desirability of dogs in parks; (4) the benefits and risks of dogs to humans and park values are poorly documented and known; (5) dogs represent a notable disease risk in some but not all countries; and (6) coastal parks are over-represented in the literature in terms of potential negative impacts. Park managers globally require better information to achieve conservation outcomes from dog management in parks.

How active are people in metropolitan parks? An observational study of park visitation in Australia

BACKGROUND: Parks are generally an under-utilized resource in the community with great potential to enhance levels of physical activity. If parks are to attract more visitors across a broad cross-section of the population and facilitate increased physical activity, research is needed to better understand park visitor characteristics and how visitors spend their time in parks. The Recording and EValuating Activity in a Modified Park (REVAMP) study is a natural experiment monitoring a park upgrade in a low socioeconomic status (SES) neighborhood. This study described the observed baseline characteristics of park visitors (age, sex) and characteristics of visitation (weekday or weekend day, period of the day) and explored how these characteristics were associated with observed park-based physical activity in two metropolitan parks located Melbourne, Australia. METHODS: Direct observations of park visitors were conducted using a modified version of SOPARC (the System for Observing Play and Recreation in Communities) on four weekdays and four weekend days. During weekdays, observations were conducted every hour from 7:30 am-4:30 pm and on weekend days from 8:30 am-4:30 pm. This equated to a total of 1460 scans across the two parks. Chi-square tests examined bivariate associations between park-based physical activity, and socio-demographic and park visitation characteristics. Logistic regression models examined the odds of being observed engaging in moderate- to vigorous-intensity physical activity relative to lying/sitting/standing according to socio-demographic and park visitation characteristics. RESULTS: In total, 4756 park visitors were observed with the majority visiting on weekend days (87 %) and in the afternoon (41 %). Most visitors (62 %) were lying, sitting or standing, with only 29 % observed engaging in moderate-intensity and 9 % in vigorous-intensity physical activity. Park use differed by time of day, sex, age group, and neighborhood SES. Physical activity was lower for women than men (OR 0.76) and higher among visitors in the high SES area (OR 1.52). CONCLUSIONS: Parks offer substantial opportunities for people of all ages to engage in physical activity; however, this study showed that a large proportion of the park visitors observed were engaged in sedentary pursuits. Further research on how park design, amenities and programming can optimize park visitation and park-based physical activity is needed.

Sisters

Melinda Capp and her sister Meredith are identical twin. The Sisters installation presented at the Castlemaine state festival is an exploration of the experience and memories of having grown up as a twin and the complexity for both the self as single and self as other/double which underpins and confronts both the physical and psychological sense being a twin. Nature / Nurture: The work is explored as a dichotomy of Nature / Nurture by referencing the domestic context of childhood (which can be interpreted as an exposition of the influence of nurture) and reference to the physical, genetic aspect of being a twin (a reference to Nature). The Installation was located in a bedroom of a 1960’s brick house, now empty, and invites the viewer to enter into a world which pulls between these two forces of nature/nurture, which shape the sense of identity and realization of self for each twin. The bond between twins emerges at the cellular level and continues for the rest of their lives. Despite all emergence of individuality and bloodline thread binds them together forever no matter the distance between them and changes through time In dark wooden wardrobe two dresses, made from fine white tissues paper, hang quietly on each side of the robe with backlighting which floods the room with an ethereal luminance. Placed in the center of a large bare wall, a small image of Melinda and Meredith as young children (a photo transfer also on the ephemeral tissue paper) hangs in isolation. This placement and the surrounding space unites these two young twins together, bound in symmetry like a mirror image in the vast open space of the empty wall, a symbol of the potential for growth and individual identity in a world which surrounds them. On the opposite wall a series of object and artifacts are pressed between sheets of acrylic and backlit as if they were some sorts of scientific samples for detailed inspection. Feathers/hair, handmade paper with embroided (reference to the traditionally feminine arts) text and the words Blood Ties traced out. Each object is placed for analysis and hovers in space at the viewers approximate eye level like a series of clues for the revelation of some deeper insight. Hidden speakers were embedded within the walls of the room and played looped recordings at low level inviting the viewer to listen as a voyeur. A series of whispered schoolyard chants by Melinda and Meredith (identical wording were individually recorded by each sister and then superimposed) and a collage of spoken word, memories and anecdotes from the period of their childhood. Most notably recollections of the Apollo Moon landing. A symbol of the ability of science to transcend and reveal that which lies beyond and within, while at the same time counterpointed by the poetics of childhood songs emerging in unison as two twins reveal their innate unification.

Tackling 'wicked' health promotion problems: a New Zealand case study

This paper reports on a complex environmental approach to addressing 'wicked' health promotion problems devised to inform policy for enhancing food security and physical activity among Māori, Pacific and low-income people in New Zealand. This multi-phase research utilized literature reviews, focus groups, stakeholder workshops and key informant interviews. Participants included members of affected communities, policy-makers and academics. Results suggest that food security and physical activity 'emerge' from complex systems. Key areas for intervention include availability of money within households; the cost of food; improvements in urban design and culturally specific physical activity programmes. Seventeen prioritized intervention areas were explored in-depth and recommendations for action identified. These include healthy food subsidies, increasing the statutory minimum wage rate and enhancing open space and connectivity in communities. This approach has moved away from seeking individual solutions to complex social problems. In doing so, it has enabled the mapping of the relevant systems and the identification of a range of interventions while taking account of the views of affected communities and the concerns of policy-makers. The complex environmental approach used in this research provides a method to identify how to intervene in complex systems that may be relevant to other 'wicked' health promotion problems.

Do enhancements to the urban built environment improve physical activity levels among socially disadvantaged populations?

Background: There is growing recognition that the urban built environment influences physical activity at the population level, although the effects on disadvantaged groups are less well understood. Using the examples of open/green space and street connectivity, this paper explores whether enhancements to the built environment have potential for addressing physical activity-related health inequalities among Mori, Pacific and low income communities in New Zealand.

Method: A high-level review of the international literature relating open space and street connectivity to physical activity and/or related health outcomes at a population level was completed. Consideration was given to whether these features of the built environment have a disproportionate effect on disadvantaged populations.

Results: Findings from international studies suggest that open space and street connectivity have a beneficial effect on physical activity. Enhancing the built environment may be particularly advantageous for improving physical activity levels among disadvantaged populations.

Conclusion: It is likely that open space and street connectivity have a positive effect on physical activity behaviour; however due to the cross-sectional nature of existing research and the paucity of research among disadvantaged populations definitive conclusions about the effect in these populations cannot be made. Further research is required (e.g. natural experiments or quasi experimental research designs) to determine the effect of changing the environment on physical activity and obesity.

Improving the health of Australians by applying evidence from behavioural epidemiology to urban design projects

Rapid urban population growth in Australia requires an expansion of supporting hard and soft infrastructure. In the State of Victoria, directing this growth are a number of urban design and planning mechanisms that provide a ‘blueprint for development and investment’. Although topics revolving around physical health are present in these and other planning related documents, largely absent from this literature are ‘tools’ to assist decision makers in determining whether or not an urban setting supports physical health and provides opportunities for physical activity. Insufficient physical activity is a risk factor contributing to Australia’s growing and significant burden of chronic disease including cardiovascular disease, Type 2 diabetes and overweight/obesity. The potential of the built environment to influence population-level physical activity is well recognised. A key element in Victoria’s planning framework that can help address these health concerns is the provision and redevelopment of open space(s) in urban areas that provide opportunities for people of all ages and abilities to engage in physical activity. However, in the realisation of these settings, evidence informing the design of urban open space(s) that promote opportunities for physical activity is needed to produce evidence based decision making. Using the three geo-spatial visioning layers embedded in Victoria’s planning framework (i.e. Growth Area Framework Plans, Precinct Structure Plans and Planning Permits) as positioning instruments, this paper merges the fields of behavioural epidemiology and urban design to: i) provide a brief overview of current research relating to design of open space to optimise usage and physical activity, ii) consider what type of evidence relating to features of open space is needed to help inform decision makers, iii) consider the methods and procedures practitioners may use to incorporate evidence in to their planning, and iv) discuss the geo-spatial development level that the respective data can best assist decision making to achieve positive gains in physical health.

The relationship between cranial structure, biomechanical performance and ecological diversity in varanoid lizards

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.Skull structure is intimately associated with feeding ability in vertebrates, both in terms of specific performance measures and general ecological characteristics. This study quantitatively assessed variation in the shape of the cranium and mandible in varanoid lizards, and its relationship to structural performance (von Mises strain) and interspecific differences in feeding ecology. Geometric morphometric and linear morphometric analyses were used to evaluate morphological differences, and finite element analysis was used to quantify variation in structural performance (strain during simulated biting, shaking and pulling). This data was then integrated with ecological classes compiled from relevant scientific literature on each species in order to establish structure-function relationships. Finite element modelling results showed that variation in cranial morphology resulted in large differences in the magnitudes and locations of strain in biting, shaking and pulling load cases. Gracile species such as Varanus salvadorii displayed high strain levels during shaking, especially in the areas between the orbits. All models exhibit less strain during pull back loading compared to shake loading, even though a larger force was applied (pull =30N, shake = 20N). Relationships were identified between the morphology, performance, and ecology. Species that did not feed on hard prey clustered in the gracile region of cranial morphospace and exhibited significantly higher levels of strain during biting (P = 0.0106). Species that fed on large prey clustered in the elongate area of mandible morphospace. This relationship differs from those that have been identified in other taxonomic groups such as crocodiles and mammals. This difference may be due to a combination of the open 'space-frame' structure of the varanoid lizard skull, and the 'pull back' behaviour that some species use for processing large prey.

Tokyo’s Dojunkai experiment: courtyard apartment blocks 1926–1932

Dojunkai apartments were constructed by the Japanese Government as a work of relief, after the Great Kanto Earthquake in Tokyo. These apartments were leading examples in concrete construction in Japan and were innovative in their exterior space design ideas and building organizational themes. Dojunkai apartments were designed not only as solutions to particular sites, but as possible models for the further development of well-planned, secure, and communal neighbourhood style residential developments. During 1920–1930, Japanese architects and designers were actively involved in experimenting with foreign concepts of urban remodelling and town planning. However while these town-planning concepts and theories were embraced by Japanese architects and town planners, the resultant apartment complexes suggest that they endeavoured to adapt and transform them to suit Japanese sensibilities and urban requirements. This paper examines the nature of these adaptations and transformations. The principles of exterior space design are deployed to examine and identify patterns in building arrangement and exterior space design for six selected Dojunkai apartments. This paper discusses the pre-existing models of urban planning in Japan to establish a relationship between the adopted foreign town-planning models and the pre-existing ideas of urban settlements in the Japanese society.

Starring in the intimate space: picture book narratives and performance semiotics

This article examines the impact of narratological pragmatics as applicable to both theatre and children picture book performances. The premise is interdisciplinary in that it negotiates points of intersection between performance semiotics and theoretical approaches to Children's Literature. Employing a comparative case study of Samuel Beckett's Happy Days and John Burningham's picture book Aldo, the research assesses the narratological outcomes of intersecting semiotic codes in relation to these specific texts.

Preparation and characterisation of open-cell microporous nickel

In the present study, nickel foams with an open cell microporous structure were fabricated by the so-called space-holding particle sintering method, which included the adding of a particulate polymeric material (PMMA). The average pore size of the nickel foams approximated 10.5 μm; and the porosity ranged from 70 % to 80 %. The porous characteristics of the nickel foams were observed using scanning electron microscopy and the mechanical properties were evaluated using compressive tests. For comparison, nickel foams with an open-cell macroporous structure (pore size approximately 1.3 mm) were also presented. Results indicated that the nickel foams with a microporous structure possess enhanced mechanical properties than those with a macroporous structure.

Mechanical properties of micro-porous metals produced by space-holding sintering

Micro-porous nickel foams with an open cell structure were fabricated by the space-holding sintering. The average pore size of the micro-porous nickel specimens ranged from 30 μm to 150 μm, and the porosity ranged from 60 % to 80 %. The porous characteristics of the nickel specimens were observed using scanning electron microscopy (SEM). The mechanical properties were studied using compressive tests. For comparison, macro-porous nickel foams prepared by the chemical vapour deposition method with pore sizes of 800 μm and 1300 μm and porosity of 95 % were also presented. Results indicated that the ratio value of 6 and higher for the specimen length to cell size (L/d) is satisfying for obtaining stable compressive properties. The micro-porous nickel specimens exhibited different deformation behaviour and dramatically increased mechanical properties, compared to those of the macro-porous nickel specimens.

Investigative interviewers' perceptions of the value of different training Tasks on their adherence to open-ended questions with children

Prior research has highlighted the considerable difficulties investigative interviewers have in adhering to open-ended questions in child abuse interviews. Although improvements in interviewing can be achieved by providing training that incorporates multiple practice opportunities and feedback, currently little is known about the way in which these elements are best administered. The current study extends debate and research on this issue by examining the perceptions of 15 trainee interviewers (police as well as social workers) regarding the relative value of various practical training exercises experienced in a recent training program. The findings indicated that although practice in interviewing was deemed essential, not all tasks were perceived to be equally beneficial. The two most favoured exercises were (a) simulated interviews involving trained actors playing the role of the child, and (b) self-evaluation of a transcribed interview using an objective coding protocol. A summary of the participants' perceptions is provided along with a discussion of the implications for trainers and researchers.
