The effects of color and light on indoor wayfinding and the evaluation of the perceived environment

This study was designed to explore the effects of color and light on indoor wayfinding and the subjective judgments of those perceiving the environment. Furthermore, how problems experienced in buildings with complex floor plans and successive spaces are addressed using variables such as color, brightness, and correlated color temperature through a desktop virtual reality environment. The experiment was conducted with the participation of 102 university students who experienced the indoor environments with various color and light variables, and evaluated these environments using concrete concepts like clear/blurry, attractive/unattractive, navigable/unnavigable and inviting/repellent. The scores for attractiveness and remembrance of warm colors were found to be higher than those for other colors, and the median scores for the positive perception of correlated color temperature were found to be higher than those concerning high and low level temperatures. However, it was confirmed that the use of warm and cool colors in indoor environments with low light levels were not taken into consideration by users of a space and were perceived negatively. Moreover, it was determined that compared to the males, females preferred high brightness levels.     

Adaptivity of wayfinding strategies in a multi-building ensemble: The effects of spatial structure, task requirements, and metric information

This study investigates the adaptivity of wayfinding strategies in a real-world setting of a multi-building ensemble. Familiarity with the environment, map usage and verbal vs. visual task instructions were systematically varied. Measures included path choices, wayfinding performance and information usage. Thirty-two participants had to find eight goals in a multi-level building ensemble consisting of two distinctive building parts. It was tested whether the standard wall-mounted floor maps found in the majority of public buildings can help navigation in a complex unknown environment. Unfamiliar users tried to make use of these plans more frequently, but were not able to compensate for spatial knowledge deficits compared to participants familiar with the setting. Two strategies of multi-level wayfinding were compared with respect to a region-based hierarchical planning approach. Strategy selection could be shown to be highly adaptive to spatial properties of the environment as well as characteristics of the task instruction, i.e., spatial precision of target information. Overall, the strategy of moving horizontally into the target building prior to vertical travel was shown to be more effective in this multi-building setting.     

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.

Effects of Place Identity,Place Dependence,and Experience-Use History on Perceptions of Recreation Impacts in a Natural Setting

It is generally accepted that recreation use in natural environments results in some degree of negative social and environmental impact. Environmental managers are tasked with mitigating the impact while providing beneficial recreation opportunities. Research on the factors that influence visitors' perceptions of environmental and social conditions is necessary to inform sound environmental management of protected natural areas. This study examines the effect of prior experience with the setting and two dimensions of place attachment (i.e., place identity and place dependence) on visitors' perceptions of three types of recreation impacts (i.e., depreciative behavior, environmental impacts, and recreation conflict). Principal components analysis, confirmatory factor analysis, and structural equation modeling were used to test the study hypotheses using data collected from 351 visitors through on-site questionnaires (response rate of 93 percent). The results show that prior experience exhibited a moderate and significant direct positive effect on place identity, place dependence, and visitors' perceptions of recreation impacts. Contrary to study hypotheses and prior research, neither place dependence nor place identity exhibited a significant effect on the dependent variables. The results show that prior experience causes visitors to be more sensitive to depreciative behaviors, environmental impacts, and recreation conflict. These findings raise concerns over potential visitor displacement and deterioration of site conditions. Implications for resource managers are discussed, which include education, modifying visitor use patterns, and site design strategies.     

Living with nuclear power: Sense of place,proximity, and risk perceptions in local host communities

Previous research notes that sense of place may intensify, and that levels of public risk perception may decrease with proximity to an established hazardous or stigmatised site. In addition, the literature suggests that sense of place may act either to mediate or moderate community perceptions of risk in such localities. This study comprised a major household survey (n = 1326) and an interview study (n = 39) and was conducted close to the nuclear power stations at Oldbury and Hinkley Point, both in the UK. It investigated the roles of perceptions of place and hazard proximity in considering (a) perceptions of risk and (b) public attitudes towards the building of a new nuclear power station in the nearby area. In addition, a novel scale was developed to measure the perceived contribution of the nearby nuclear power station to sense of place. The results suggest first, that sense of place mediates (but does not moderate) perceptions of risk in very proximate communities, and second, that public attitudes to new build in communities situated very close to established nuclear sites may be largely dependent on the extent to which the existing facility is perceived to contribute towards sense of place. The implications of these results for existing theory are discussed.     

Home beyond the house: Experiences of place in an evolving retirement community

This research presents the results of a qualitative study of a small sample of older adults (n = 25), age 55+ who have recently moved to an area that is rapidly changing from a tourist community into a retirement community. The study has two main research objectives: (a) to use Oswald and Wahl's heuristic meaning of home framework to explore the relationships between older adults and their homes and communities, integrating theories from environmental psychology, environmental gerontology and human geography, and (b) to discuss the empirical findings focussing on the core concepts of meaning of home and sense of belonging for new retirees to an area. Findings: For new retirees, there exists a zone between the home and community, that can be viewed as a geographic space comprised of overlapping and interwoven personal, social and physical domains. This zone between the physical house and the surrounding community can be construed as having certain elastic qualities and permeable boundaries that blur the distinctions between home and community. A focus on the micro-environment of the home dwelling and the macro-environment of the neighbourhood and community then appears relevant for understanding place attachment for these persons. This idea of the ‘home beyond the house’ – is one of the most important contributions of this research. Our results view the heuristic framework of Oswald and Wahl as a valuable tool for building understanding about the meaning of home for older adults by drawing attention to the domains themselves, and more importantly, to the interrelationships between them. Consequently, for younger in-migrants, the boundary between home and community blurs into one larger, symbolic entity experienced as ‘home’.     

Biomass combustion and indoor air pollution: the bright and dark sides of small is beautiful

About half the world's households cook and/or heat daily with biomass fuels. At small scale, biomass combustion releases significant amounts of particulates, carbon monoxide, and hydrocarbons, the latter with significant concentrations of polycyclic aromatic hydrocarbons. Preliminary measurements in kitchens of developing-country villages have established airborne concentrations of these healthdamaging pollutants that are orders of magnitude above urban levels or relevant standards. Particle size measurements and dose calculations lead to significant concerns about potential health hazards. The few epidemiological studies are consistent with such effects although more work is clearly needed. These findings may have significant implications for the planning of rural energy development in a number of countries. In particular, they may relate directly to the question of the optimum balance between centralized and decentralized systems.     

Food risks and the environment: changing perspectives in a changing social order

Risks related to food production and consumption are not a recent phenomenon. Through agricultural practices, the transport of agricultural and food products, the processing of food, its storage, and finally the consumption of food, risks have been externalized, mediated, contested and ingested. But agrofood systems have also been paralleled by routinized practices and institutions that attempt to reduce risks and sustain trust among the many actors involved in these food regimes. However, both the (definition of) food risks and the institutions and discourses used to dispel anxiety and build trust are far from stable throughout time. In the contemporary modern world-order, food risks and the practices and institutions dealing with these risks reflect the significant transformations in the agrofood system, the changing nature of the risks involved in food production and consumption, and the modifications in scientific risk assessment and risk management. This article provides an overview of the current debates, discussions and practices on actual and potential institutional transformations that parallel the emergence, assessment and management of food risks in reflexive modernity.

Addressing disputes in a coalition framework: The case of agriculture and the environment

A coalition framework is proposed to address the contentious issues facing agriculture and the environment in urbanising areas, by bringing stakeholders together in homogeneous focus groups to identify areas of common interests, and then in heterogeneous groups to validate the results of the framework. Such a framework encourages greater understanding, consensus building, the resolution of conflicts, and the establishment of coalition efforts in areas of mutual interest and agreement by allowing stakeholder groups collectively to pursue agenda-building on issues of common interests. Based on the authors' observation of the process over an 18-month period, it is encouraging that the coalition framework is an appropriate strategy for building consensus among diverse audiences.     

Comparison of models of simazine transport and fate in the subsurface environment in a citrus farm

Contamination of groundwater by agrochemicals is now widely recognized as an extremely important environmental problem. Modern agricultural practices involve the combined use of irrigation with the application of large amounts of agrochemicals to maximize crop yield. Due to flood irrigation and natural runoff, agricultural activities might generate soil, surface water and groundwater contamination problems and leaching of pesticides. Modeling of the transport and fate of pesticides, such as simazine, may help understand the long-term potential risk to the subsurface environment. This paper illustrates a comparative study via the use of three different pesticide transport simulation models and the applicability of those models in determining the groundwater vulnerability to pesticides contamination in a citrus orchard located at the Lower Rio Grande Valley (LRGV). The three models used in the study are the pesticide root zone model-3 (PRZM-3), the pesticide analytical model (PESTAN) and integrated pesticide transport modeling (IPTM). The concentration values obtained from all three models are in agreement, and they show a decreasing trend from the surface through the vadose zone. The problem is how to use this information and, specifically, how to combine the testimony of a number of experts into a single useful judgment. With the aid of the fuzzy multiattribute decision making method, PRZM-3 is deemed as the most promising one for such precision farming applications.     

Mining and the environment: a case study from Bijolia quarrying site in Rajasthan, India

Mining is essentially a destructive developmental activity, where ecology suffers at the altar of economy. Unfortunately, in most regions of the Earth, the underground geological resources are superimposed by biological resources (forests). This is particularly evident in India. Hence mining operations necessarily involve deforestation, habitat destruction, biodiversity erosion and destruction of geological records which contain information about past biodiversity. Extraction and the processing of ores and minerals also lead to widespread environmental pollution.However, mankind cannot afford to give up the underground geological resources which are the basic raw materials for development. An unspoiled nature can provide ecological security to people but cannot bring economic prosperity. Scientific mining operations accompanied by ecological restoration and regeneration of mined wastelands and judicious use of geological resources, with search for eco-friendly substitutes and alternatives must provide the answer.A case study from the Bijolia quarrying area in Rajasthan, India, provides some sensational revelations of the impact of mining on the human ecosystem.

Pictorial intervention in a pediatric hospital environment: Effects on parental affective perception of the unit

In recent decades, research on health care design and planning has highlighted the strong relationship between environmental characteristics and human health. According to a patient-centered model, the focus on the hospital environment is important in reducing the negative effects of hospitalization on the patient, especially in the case of children.     

Measurement and assessment of carrying capacity of the environment in Ningbo, China

Carrying Capacity of the Environment (CCE) provides a useful measure of the sustainable development of a region. Approaches that use integrated assessment instead of measurement can lead to misinterpretation of sustainable development because of confusion between Environmental Stress (ES) indexes and CCE indexes, and the selection of over-simple linear plus models. The present paper proposes a comprehensive measurement system for CCE which comprises models of natural resources capacity, environmental assimilative capacity, ecosystem services capacity, and society supporting capacity. The corresponding measurable indexes are designed to assess CCE using a carrying capacity surplus ratio model and a vector of surplus ratio of carrying capacity model. The former aims at direct comparison of ES and CCE based on the values of basic indexes, and the latter uses a Euclidean vector to assess CCE states. The measurement and assessment approaches are applicable to Strategic Environmental Assessment (SEA) and environmental planning and management. A case study is presented for Ningbo, China, whereby all the basic indexes of ECC are measured and the CCE states assessed for 2005 and 2010.
