THE NEED FOR CONTROLLED INFORMATION PROCESSING IN THE VISUAL ACQUISITION OF ROUTE KNOWLEDGE

The route knowledge of participants who performed a concurrent task during a simulated route-learning exercise was compared to that of participants engaged only in the route-learning exercise by employing tests of scene recognition, distance estimation and map verification. Results indicated performance decrements on the scene recognition and distance estimation tasks on the part of participants in the concurrent task condition, thus supporting the interpretation that these tasks were sensitive to the reduction in available attentional resources. Performance on the map verification task was generally poor, a fact that may have masked the general effect of the concurrent task manipulation. Comparisons involving only those subgroups for which performance was above chance level provided evidence that this task was also sensitive to the availability of resources. In addition, results from the map verification task clearly pointed to map orientation as an important factor influencing the ability to recognize a cartographic representation of a path of movement within a large-scale environment.     

A phenomenographical approach to the study of pre-adolescents' use of maps in a wayfinding exercise in a suburban environment

This paper reports the investigative study, which used a phenomenographical approach, on how a group of 12-year-old students found their way around a designated suburban route by referring to a sequential listing of streets along the route and a street directory map of the suburban area. While the content of this study belongs to map use and wayfinding experience of the pre-adolescent students, the approach used is phenomenographic in that it identified the qualitatively different ways that the students experienced the suburban environment. The students' experiences were interpreted using a behaviourial matrix of their actions while they traversed the route. Qualitative variations in their approaches to wayfinding using maps were obtained from interviews which were conducted immediately after the students completed their route navigation. Four qualitatively different approaches were determined from their reflections of their own wayfinding behaviours. They are the restricted and neophytic approach; careful and sequential approach; deductive and familiarized approach; and the visualized and co-ordinated spatial approach. These approaches reflect the different behaviours and abilities of the students to: plan their route using a street directory map; plan the route street by street or a number of streets at a time; use street signs and other landmarks during the actual task; utilize local knowledge of the route; maintain their orientation; visualize spatial patterns; and use the scale on the map to help planning.     

Children's Access to Local Environments: A case-study of Christchurch,New Zealand

This article provides a case-study of variability in children's independent access to their local environments in the New Zealand city of Christchurch. It is based on research with children in middle childhood, parents and teachers in four schools in Christchurch, each selected on the basis of variables hypothesised to impact on children's access to their local areas. The paper outlines why such independent access is of value, not only for children, but also for adults responsible for their safety, for the wider environment and for the local community. Variability within Christchurch is related to the socio-spatial nature of local environments. International comparisons are also made, drawing out the implications of differing cultural contexts for the pursuit of child-friendly cities. The article explores the role of social traps in impeding the creation of a more sustainable, child-friendly city.     

TWO STRATEGIES FOR LEARNING A ROUTE IN A DRIVING SIMULATOR

The study of human navigation has long been dominated by the so-called stage theory, i.e. the notion that there are three distinct types of spatial knowledge (landmark, route, and survey knowledge), that are acquired sequentially during spatial learning and development. Based on the results of a route learning experiment in a driving simulator, an alternative to the stage theory is proposed. The authors suggest that subjects follow either a visually dominated or a spatially dominated strategy to solve a route-learning problem. In the visually dominated strategy, subjects base their wayfinding decisions on visually recognizing decision points along a route; the decision points are not integrated into any kind of survey representation. In the spatially dominated strategy, on the other hand, subjects represent the environment as a survey map right from the start; that is, they do not pass through a landmark or route stage. These strategies may be subserved by different cortical areas recently characterized in neurophysiological studies of animals solving maze problems.     

A Defense of Animal Rights

I argue that animals have rights in the sense of having valid claims, which might turn out to be actual rights as society advances and new scientific-technological developments facilitate finding alternative ways of satisfying our vital interests without using animals. Animals have a right to life, to liberty in the sense of freedom of movement and communication, to subsistence, to relief from suffering, and to security against attacks on their physical existence. Animals’ interest in living, freedom, subsistence, and security are of vital importance to them, and they do not belong to us; they are not the things we have already possessed by virtue of our own nature.     

Locational Errors in Maps from Environmental Surveys and Their Implications for Information Extraction

1.Information on all maps, including those which depict characters of the natural environment, is subject to locational error. 2.Locational errors on field-sketched maps are attributable to inaccuracies both in the base map itself and in the method of locating and recording features onto the base map. 3.Two main sources of error associated with field sketch mapping were quantified using the River Corridor Survey maps as an example. First, channel widths are routinely exaggerated on these maps to allow recording of in-channel features. Distortions of river bank length of the order of 25% were shown to arise from a four-fold exaggeration of the width of a sinuous channel. Second, discrepancies in feature location of the order of 20% were found along a 500 m river stretch, although errors could be reduced to approximately 2% if undistorted, large-scale base maps were used. 4.An abundance scale appropriate to the inherent locational inaccuracy was devised to extract semi-quantitative information from River Corridor Surveys recorded on distorted base maps. Application of this scale to 29 River Corridor Survey maps of a 14·5 km river corridor produced a useful representation of environmental gradients within the corridor. 5.With the increasing potential to integrate and analyse environmental information within large computer databases including Geographic Information Systems, it is essential that the level of accuracy is recognised and quantified so that the errors can be allowed for in the development of methods of extracting information from the maps.     

“Because we are all people”: outcomes and reflections from young people's participation in the planning and design of child-friendly public spaces

Child-Friendly Cities were conceived as a means to integrate children's rights into city decision-making and governance. Participatory research about child-friendly cities consistently finds overarching themes across ages and regions: children desire access to services, nature, and play; freedom from physical danger; and opportunities for inclusion within the city. This article explores a two-year visioning and participatory design process that engaged approximately 225 young people, aged 4–16, in the planning and design of a prominent public space in the City of Boulder. While participatory research with children has received much attention in the academic literature, much less attention has been given to what can be achieved through sustained integration of children into municipal planning processes, particularly in the USA. This paper thus moves children's participation beyond rhetoric and into the challenging reality of planning a city with children as a valued constituent.     

Traffic noise and executive functioning in urban primary school children: The moderating role of gender

The objective of this study was to examine the relationships between noise and school children's executive functioning (EF). The study included 311 children (146 boys and 165 girls) aged 7–11 years, who lived in the center of Belgrade. Teachers rated children's EF on a standard scale evaluating their ability to work independently in a focused manner to achieve an end goal as well as children's ability to follow directions carefully. Residential noise exposure was estimated in three daytime intervals, one evening interval and two nighttime intervals in the middle of the streets where children lived. School noise exposure was measured on three different school days in front of children's schools. Socioeconomic status (mother's highest level of education and family income) was used as a statistical control. There were no significant main effects of ambient noise levels on EF, however, a significant interaction indicated adverse noise impacts on boy's EF. We discuss possible reasons for male EF vulnerability to noise.     

Parental perception of social risk and of positive potentiality of outdoor autonomy for children: The development of two instruments

An important factor that limits children's autonomy outdoors is parental perception of social danger and traffic danger. To obtain quantitative instruments for these dimensions, this work aimed to explore the validity and reliability of three scales. Two of them describe, respectively, problematic aspects of the area of residence linked to traffic and situations of social degradation that could constitute risk factors for the child's psychological and physical safety (Traffic Danger Perception Scale, Social Danger Perception Scale). The third scale investigates parental perception of the positive potentiality of outdoor autonomy for children's maturation and growth. Interviews were conducted with 377 mothers of children between 8 and 10 years of age residing in six different areas in Italy. The results indicated weak reliability of the Traffic Danger Perception Scale, which requires further investigation, and they confirmed the reliability and the construct validity of the Social Danger Perception Scale and the Perception of Positive Potentiality of Outdoor Autonomy for Children Scale. The perception of social danger was higher in mothers who live in larger urban contexts and who have more personal fear of crime and a lower sense of community. The positive perception of children's autonomy of movement was higher among mothers who live in greener areas, who have a greater sense of community and who have more neighbourhood relations.     

Autonomy and the Politics of Food Choice: From Individuals to Communities

Individuals use their capacity for autonomy to express preferences regarding food choices. Food choices are fundamental, universal, and reflect a diversity of interests and cultural preferences. Traditionally, autonomy is cast in only epistemic terms, and the social and political dimension of it, where autonomy obstruction tends to arise, is omitted. This reflects problematic limits in the Cartesian notion of the individual. Because this notion ignores context and embodiment, the external and internal constraints on autonomy that extend from social location are not considered. Therefore, reconceptions of the individual and autonomy which emphasize social location and relational interdependency are needed. To combat autonomy obstruction, individuals can appeal to community and community autonomy as a social mechanism. Communities are social groups characterized by people living in places with shared goals. Recognizing their interdependency, individuals can organize as communities in order to accomplish objectives that they cannot on their own. While community autonomy is valuable unto itself, it can also enhance individual autonomy.     

Children's perspectives on playground use as basis for children's participation in local play space management

Implementing children's perspectives into playground management could be a way of improving play possibilities for children in the local public space and supporting sustainable development, but it requires adults' understanding. Children's perspectives on playground use were studied through group interviews in two Swedish towns and were also compared with the understanding among the local park workers. Children described their playground use through challenges, manipulation and place-making, something which was partly recognised by the park workers. The results indicate that children's perspectives on playground use, particularly manipulation, should be implemented more fully into management work. Children's participation in on-site management activities is discussed as a way of making playgrounds more adapted to children's use and perspectives.     

Environmental representatives: whom,what, and how are they representing?

Literature on environment and representation in politics, management, and deliberation has paid little attention on the people involved: environmental representatives. The aim of this paper is to illuminate how environmental representatives in various organizational and professional contexts understand their role as representatives, and how they are shaped by their contexts. The paper argues that it is crucial to learn about the everyday reality of individual representatives to better understand the limitations and possibilities they face. The study is based on 19 interviews with environmental representatives from five organizational and professional contexts: the state, civil society, business, science, and media in Sweden. The paper concludes that some differences in experiences, for example, in freedom and constraint, can be understood in relation to the representatives’ organizational and professional affiliation. Other experiences are common: (i) all categories stated the importance of being impartial and well read; (ii) complex layers of affiliation imply that representation requires sensitivity and adjustment between different situations; and (iii) the performative aspects of representation include the representatives’ claims-making, others’ attributions, and long-term learning of their role. The article contributes an understanding of organizational conditions and the often paradoxical, layered, multifaceted, and cautious representation these individual actors perform.     

Commuting lives: children's mobility and energy use

Globally, the issue of energy use and climate change is at the forefront of many national and international agendas, and also an issue central to children's lives and well-being. This paper examines how children are both affected by and contribute to the problems associated with unsustainable energy use as it relates to the growth of car dependent lives. The paper presents the findings of a study of travel as it relates to the everyday lives of children in the city of Dunedin in New Zealand. The study found that children currently lead complex car dependent lives. This extensive car reliance presents a serious and largely unrecognised challenge to the sustainable planning and management of the urban environment. The move towards more sustainable transportation can bring benefits for both the environment and for children's lives.     

The role of perceived government style in the facilitation of self-determined and non self-determined motivation for pro-environmental behavior

Most North Americans are concerned about the environment and feel that responsibility for its protection lies primarily with government; however, no research to date has examined the influence of the government's approach toward environmental regulation on the motivation of individual citizens. According to self-determination theory, social contexts that support one's autonomy should facilitate self-determined motivation and social contexts that thwart autonomy should lead to non self-determined motivation and a sense of apathy or amotivation. In this study (n = 283), we examined the influence of perceptions of the government's approach toward environmental regulation on motivation toward the environment and frequency of self-reported pro-environmental behavior (PEB). Using structural equation modeling, we tested the hypothesis that frequency of PEB is predicted by motivation toward the environment and that motivation is predicted by the extent to which individuals perceive the government to be autonomy-supportive versus controlling in the implementation of environmental policies. The analysis revealed that perception of government autonomy-support contributed positively to autonomous motivation and negatively to amotivation, while perception of government control was positively related to both controlled motivation and amotivation. As predicted, autonomous motivation was positively, and amotivation was negatively, associated with frequency of PEB.     

Bridging conceptual “silos”: bringing together health promotion and sustainability governance for practitioners at the landscape scale

Environmental health issues are examples of “wicked problems” that require cross-sectoral collaboration at the community level, yet health practitioners and environmental stakeholders find it challenging to see how and why they could be working together. Supportive organisations have been identified as the most vital enabler for individual professionals to participate actively in cross-sectoral initiatives. Ability to justify inter-professional cooperation makes it easier for practitioners to gain the necessary approvals within their institutional mandates. This paper introduces a new conceptual framework that bridges health promotion and sustainability governance to facilitate practical cross-sectoral collaboration that targets complex health-related environmental and social-ecological challenges. The proposed framework integrates six concrete overlapping themes linking health promotion and sustainability governance. The framework also highlights examples of areas where the fields could benefit from one another. Moreover, children's environmental health is proposed as a desirable overall outcome and an attractive venue for potential collaboration, because of its critical role in the public health and well-being of future generations. As a determinant of adult health, children's environmental health emphasises the vital interdependencies between health and the environment.     

We should allow dissection of animals

The focus of the paper is the ethical issues associated with the practice of dissecting animals in lower level college biology classes. Several arguments against dissection are explored. Furthermore, the issue is examined from the point of view of the instructor's academic freedom and the point of view of a student's moral autonomy. It is argued that even though the arguments against dissection fail, it is very important to respect the moral autonomy of students who oppose the practice. Often this can be accomplished in a manner that is consistent with academic freedom and good science education.     

Wayfinding with a GPS-based mobile navigation system: A comparison with maps and direct experience

This study examined the effectiveness of a Global Positioning System (GPS)-based mobile navigation system in comparison to paper maps and direct experience of routes, by focusing on the user's wayfinding behavior and acquired spatial knowledge. Based on information received from one of these three media, participants walked six routes finding the way to goals. Results showed that GPS users traveled longer distances and made more stops during the walk than map users and direct-experience participants. Also, GPS users traveled more slowly, made larger direction errors, drew sketch maps with poorer topological accuracy, and rated wayfinding tasks as more difficult than direct-experience participants. Characteristics of navigation with these three learning media and possible reasons for the ineffectiveness of the GPS-based navigation system are discussed.     

CHILDREN'S SENSE OF PLACE IN NORTHERN NEW MEXICO

In the Hispano homeland of northern New Mexico, children's lives are shaped by land, by family, by culture, and by community. The way these forces work together forms each child's sense of place and place attachments. Using short case examples, this article presents a brief overview of children's place experiences and preferences and describes some of the factors that contribute to children's sense of place in three communities, of northern New Mexico which represent a range from urban to rural. It demonstrates the important role extended family and direct experience play in shaping children's sense of place and understanding of nature.     

Landmarks’ use in speech map navigation tasks

Tools for assisting human navigation, especially in-vehicle systems, have been extensively investigated. However, few studies have explored the design of speech-based over-the-phone guidance systems. This study examined the effect of landmarks' use and the effect of landmarks’ frames of reference in route instructions on navigation efficiency during map navigation tasks and satisfaction. Twenty-seven participants performed map navigation tasks using a simulated speech navigation system in three experimental conditions: instructions containing no landmarks, instructions containing landmarks located without reference to either the traveler’s body or the surrounding environment, and instructions containing landmarks located with respect to the traveler’s body. Navigation performances on maps were higher and landmarks enable participants to make fewer directional errors and find their routes more efficiently. Satisfaction levels and navigation performances were lower when instructions did not contain any landmarks. Landmarks’ frames of reference shifting turned out to be different between human-human situations previously used and human-computer situations used here.
