Beyond savanna: An evolutionary and environmental psychology approach to behavioral effects of nature scenery in green advertising

Evolutionary psychology has been proposed as an analytic framework for the behavioral effects of landscapes displayed in advertising. In this study, an evolutionary and environmental psychology approach is used to analyze affective reactions to advertising depicting specific natural environments or urban scenes, both prominent ingredients of contemporary advertising imagery. The experimental field study exposed 750 participants at random to one advert of a set of 13 experimental green energy advertisements, each displaying a different biome. Six basic emotional responses (pleasure, arousal, happiness, freedom, safety, and interest) as well as attitude toward the ad and brand attitude were assessed subsequently. Anova and structural equation analysis were used for data analysis. Results of the study confirm the leading opinion on generalized more positive behavioral effects toward visual stimuli representing nature scenes with biospheric contents as opposed to pictures of urban environments or desert settings. In line with earlier empirical research, further findings do not support the hypothesis on an innate preference for savanna landscapes in adults but confirm preferences for images of lush green landscapes with water and familiar biomes. Overall results give significant support to the application of environmental and evolutionary psychology to advertising.     

Correlates of pro-sustainability orientation: The affinity towards diversity

The concept of affinity towards diversity (ATD) is introduced and illustrated with two studies on the psychological drivers of pro-sustainability orientation and environmentally friendly behaviors. In light of the importance that biological and social ecological sciences assign to diversity within socio-ecological systems, ATD was conceptualized as an individual predisposition to appreciate the dynamic variety of human–nature interactions in everyday life situations. ATD implies valuing and liking biological and socio-cultural diversity, more than simply being respectful before or accepting differences in the social and physical contexts. Two different samples of Mexicans responded to a series of scales, one of them assessing ATD. The scale exhibited an acceptable level of internal consistency and it also showed construct validity, according to the results of two structural equation models. A first study showed that ATD significantly and negatively covaries with a scale of intolerance, and positively covaries with a measure of environmentally friendly behavior. A second study revealed also that ATD, together with other psychological factors (future orientation, altruism, emotions towards nature), forms the basis for a pro-sustainability orientation which, in turn, predicts environmentally friendly behaviors.     

The connectedness to nature scale: A measure of individuals’ feeling in community with nature

Five studies assessed the validity and reliability of the connectedness to nature scale (CNS), a new measure of individuals’ trait levels of feeling emotionally connected to the natural world. Data from two community and three college samples demonstrated that the CNS has good psychometric properties, correlates with related variables (the new environmental paradigm scale, identity as an environmentalist), and is uncorrelated with potential confounds (verbal ability, social desirability). This paper supports ecopsychologists’ contention that connection to nature is an important predictor of ecological behavior and subjective well-being. It also extends social psychological research on self–other overlap, perspective taking, and altruistic behavior to the overlap between self and nature. The CNS promises to be a useful empirical tool for research on the relationship between humans and the natural world.     

The desirability of views of city skylines after dark

Three studies used digital color photographs to compare responses to natural scenes, skylines after dark, and skylines during the day (seven of each). Study 1 had 59 respondents rate the pleasantness of each scene. They gave similar ratings to Night Skylines and Natural Scenes, and rated each as more pleasant than the Day Skylines. Study 2 had 56 other participants choose from each of seven sets of each kind of scene the one they would most like to have as a framed print in their home or office, and to report the reasons. Participants chose Night Skylines most often, followed by Natural Scenes and then Day Skylines. While participants most often picked attractive as a reason for their choice, those who chose Night Skylines also picked exciting as the reason, and those who picked Natural Scenes also picked relaxing or peaceful as a reason. Study 3 obtained ratings of selected formal features of each scene. The 23 judges rated the Natural scenes as more natural, orderly, open, and curvilinear, less complex, and as having smoother transitions than either Day or Night Skylines; and they judged the Night Skylines as higher in complexity but lower in order than Day Skylines. The results suggest that preferences in relation to the scene categories may well depend on a mix of their formal characteristics and their content.     

The prediction of scenic beauty from landscape content and composition

Two studies were conducted to examine distance classes of vegetation (foreground, middleground and background) and scene composition (presence of vegetation in left, center or right section of the image) as predictors of perceived scenic beauty. In study one, 41 students rated 63 landscape scenes with regard to scenic beauty. The Scenic Beauty Estimation Method was used to derive interval scale beauty values (SBEs). For each landscape image, areal measures of vegetation in each distance class and for each vertical section were taken and used as predictors. Presence of haze, clouds and human impacts were also recorded. Among the most important contributors to scenic beauty were amount of center middleground vegetation, and center background vegetation. Left foreground vegetation and right foreground vegetation were found to have significant and opposing regression weight signs—negative for the left and positive for the right. Study two was conducted to determine whether these opposing regression weight signs for foreground vegetation were due to a perceptual right-left bias or to some specific content in the image itself. In the second study, the photographic slides used to present landscape scenes to subjects were reversed so that the content which was previously on the right was now left, and vice versa. Thirty-nine students rated the reversed slides with regard to their scenic beauty. The signs of the regression weights in study two shifted such that left foreground was now positively valued and right foreground was negatively valued. This finding suggests that viewers are sensitive to foreground content and its placement in the image, and not simply to one side of the field of vision.     

Connecting with Country in Mungo National Park,Australia: a case study to measure the emotional dimension of experience and place attachment

Connecting people with nature improves well-being, but how people connect with natural places is not well documented. We asked 43 people (19 Aboriginal Australians, 24 non-Aboriginal people) about the messages they received from Country during an interactive experience in the remote Mungo National Park, Australia, and analysed the physical senses, emotions and cognitive processes they mentioned. The physical senses mentioned by most respondents were sight, hearing and motion (particularly walking). These senses helped people receive messages from Country and connect with place. We used the primary-process emotional systems of Panksepp [2010. Dialogues in Clinical Neuroscience, 12 (4), 533–545] as a framework to capture the emotional dimension of experience. Most people reported positive emotions; they spoke about being nurtured by the group and the land (CARE), and the intense joy (PLAY) of being part of the community, being on Country and being accompanied by Aboriginal people. However, our results indicate the framework does not capture the breadth of positive emotions, particularly those associated with connection to place and spiritual experiences. Both groups mentioned cognitive processes reflecting their beliefs, existing knowledge, or sharing and acquiring new knowledge. Our results indicate that the emotional dimension of experience has the potential to measure connection to place, and provide a subjective measure of well-being. More research is needed to document this dimension of experience, and how it changes with context. Our case study provides further insight for those who manage protected areas and seek to enrich the experience of visitors.     

When context matters: a multilevel analysis of household and neighbourhood crowding on aggression and withdrawal

Studies examining the effects of density and crowding on human social behaviour have produced inconsistent results. This paper argues that among the reasons for these varied findings are: (1) the failure of researchers to examine how the level of density in the wider contextual environment influences the nature of the relationship between household density and social behaviour; (2) the tendency of past studies to overlook the negative consequences of both very low and very high levels of density; and (3) a lack of research investigating whether multiple coping strategies to high-density environments may be invoked by a single individual. Data from the Toronto Mental Health and Stress study are analysed using hierarchical nonlinear modelling to assess the interaction between household and neighbourhood density effects on aggression and withdrawal. The results support the notion that the effects of density on aggressive and withdrawn behaviour are nonlinear in nature and that the impact of household density is conditional on neighbourhood density. The implications of these findings for future research on density are discussed.     

Effects of labelled meaning on the affective quality of housing scenes

A series of studies examined the effects of labelled meaning on affective response to housing scenes. Students at Ohio State University assessed their feelings towards imagined housing (public or private) and cities (Memphis, Houston and San Francisco). Expected differences in the affective quality were found. Responses to color photographs of specific housing scenes labelled as either private condominiums or public housing were obtained. Differences in scene-affect as a function of labelled meaning were found. Responses to housing scenes labelled as located in either Memphis, Houston or San Francisco revealed no differences in scene-affect as a function of label meaning. This latter finding was confirmed in a non-repeated measure examination. Differences in the fittingness, potency or relevance of the information provided may account for the pattern of findings.     

Towards a sustainable economy? Socio-technical transitions in the green building sector

Making the transition to a green economy is a major policy driver in the UK and other countries. Entrepreneurs are suggested as being at the forefront of this transition and as a driving force for sustainability. These “green entrepreneurs” may represent a new type of entrepreneurial behaviour combining economic, environmental and social aims. In this paper, we present empirical work conducted with green entrepreneurs in the UK green building sector. Buildings have significant impacts on the environment, both in terms of materials and post-construction energy demands. Drawing on sustainability transitions theory, we examine the role of green entrepreneurs in affecting change and suggest that green building niches are less consensual than previously theorised. In theorising green entrepreneurs, we also point to the need to consider them within wider networks of activity rather than as lone actors and the implications this has for policy.     

“My garden is an expression of me”: Exploring householders' relationships with their gardens

Domestic gardens offer immense potential as sites for native biodiversity conservation. In urban areas they often comprise the largest land use, thus presenting an accessible and immediate way for urban dwellers to connect with nature and to support and enhance native biodiversity. This paper presents findings from a study of 55 domestic gardens undertaken in Dunedin, New Zealand, which explores householders' relationships with their gardens. The study data was derived from two interviews with householders, two photo exercises (approximately a year apart), together with a number of biological studies of the gardens. Gardens proved to be very important for our householders; for physical and mental health, as an expression of ownership and identity, as sites for social relationships, for connecting with nature and as site of domestic produce production. Householders' connections with nature were idiosyncratic, multifaceted and exhibited in ways that are more complex and varied than those usually considered by those working in the natural sciences and indeed biophilia supporters. We emphasize the importance of the people side of nature in seeking to build and support positive ecological change in the urban environment and the value of combining natural and social science approaches.     

Dead indoor plants strengthen belief in global warming

Studies have revealed that heuristics and accessible schemas may affect people's judgments about global warming. In two studies, participants were asked to report on beliefs regarding global warming while seated in a room in which a small tree or several trees had been placed. In one experimental condition, the tree possessed its foliage whereas in the other, the branches were bare. It was found that participants were more likely to believe in global warming in presence of the tree without foliage (Study 1), that this belief increased in presence of three rather than one tree without foliage (Study 2), and that other beliefs not related to global warming were not affected by the experimental conditions. These results reveal that surrounding physical cues do affect beliefs about global warming. The spreading activation theory is used to explain these results.     

Residential satisfaction in council housing

Planners' and architects' knowledge of the needs of users as well as their perceptions of the residential environment, has been commented on in many studies dealing with residential satisfaction. In this study—based on primary research in an area of council housing in Madrid—the main goal is the study of objective and subjective factors, on both physical and social levels, which influence council housing residents' satisfaction. A sample of 447 housewives responded to a questionaire, a multiple regression analysis of which showed that attachment to the neighbourhood and relationships with neighbours explained the greatest variance in residential satisfaction. Some methodological issues about the measurement of residential satisfaction are also discussed.     

Benefits-based analysis of visitor use of Sorak-san National Park in Korea

Benefits-based management seeks to provide recreation benefits for recreation participants by managing the physical environments in which recreation occurs. This study investigates the relationship between benefits desired by visitors and the physical, social, and managerial characteristics of settings that facilitate realization of recreation benefits. Data such as perceived benefits from recreation experiences, setting attributes that significantly influenced perceived benefits, and sociodemographic variables were collected from 376 visitors to Sorak-san National Park in the eastern part of the Korean peninsula. Cluster analysis was used to group visitors' desired benefits into 12 domains: relationship with nature/scenery, escaping pressure, learning about nature, family togetherness, introspection, exploration, autonomy/achievement, being with friends, leading others, skills/learning, risk taking, and meeting/observing new people. Multiple regression was used to link benefit domains with the characteristics of settings. The social attribute of recreation settings was linked to eight of the ten benefit domains. There were two statistically strong multiple regression correlations: (1) between domain of “relationship with nature /scenery” and the attributes “forest/water,”“attractive nature,” and “facility/maintenance” and (2) between the domain of “escaping pressure” and the attributes “attractive nature” and “social.” The results of this study are useful to managers in their efforts to provide recreation opportunities for visitors to achieve beneficial outcomes.     

Perceptions of the security and attractiveness of urban parking lots

This study concerns design features of urban parking lots which can increase the perception of such areas as both safe and attractive. College students evaluated the attractiveness and perceived security associated with 180 scenes of parking lots adjacent to commercial and multi-family residential structures in Atlanta and Athens, Georgia, U.S.A. High intergroup correlations (r > 0·90) indicated the reliability of evaluations of both perceived features. Regressions of physical features on perceived security ratings and attractiveness ratings yielded highly predictive models (R² = 0·76 and 0·80, respectively). For both sets of ratings a Maintenance and Design factor accounted for the most variance. Although attractiveness ratings were higher as the total amount of vegetation increased in a scene, security was in general rated higher only when vegetation was well maintained and appeared to be installed as part of a landscape design. Attractiveness was generally higher for multi-family residential scenes than for commercial scenes. Perceived security was higher for frontal views of structures, especially when entrances were proximate to the viewer. Research implications are discussed in terms of the impact of natural features in urban areas for increasing attractiveness and reducing fear of crime.     

Legitimizing Fluvial Ecosystems as Users of Water: An Overview

We suggest that fluvial ecosystems are legitimate users of water and that there are basic ecological principles guiding the maintenance of long-term ecological vitality. This article articulates some fundamental relationships between physical and ecological processes, presents basic principles for maintaining the vitality of fluvial ecosystems, identifies several major scientific challenges and opportunities for effective implementation of the basic ecological principles, and acts as an introduction to three specific articles to follow on biodiversity, biogeochemistry, and riparian communities. All the objectives, by necessity, link climate, land, and fresh water. The basic principles proposed are: (1) the natural flow regime shapes the evolution of aquatic biota and ecological processes, (2) every river has a characteristic flow regime and an associated biotic community, and (3) aquatic ecosystems are topographically unique in occupying the lowest position in the landscape, thereby integrating catchment-scale processes. Scientific challenges for the immediate future relate to quantifying cumulative effects, linking multidisciplinary knowledge and models, and formulating effective monitoring and assessment procedures. Additionally, forecasting the ecological consequences of changing water regimes is a fundamental challenge for science, especially as environmental issues related to fresh waters escalate in the next two to three decades.     

Objective exposure to road traffic noise,noise annoyance and self-rated poor health – framing the relationship between noise and health as a matter of multiple stressors and resources in urban neighbourhoods

Borrowing from concepts of socio-environmental epidemiology and psychology, we conceived self-rated health as a function of multiple physical and psychosocial stressors and resources at the residential neighbourhood and individual level. In this model of multiple stressors, objective exposure to road traffic noise was specified as a physical stressor whose effect on health may be mediated and modified by residents’ subjective response to noise (serious noise annoyance). Self-reported hearing disability, recreational coping in green areas and residential neighbourhood satisfaction were examined as additional psychosocial stressors or resources, independently of socio-demographic and -economic factors. Results from our empirical analysis based on two studies and multivariable logistic regressions might support the idea that environmental planning should overcome sectoral boundaries and adopt an integrative approach including objective exposures, residents’ subjective responses, and perceived resources.     

An empirical study on the public perception and acceptance of hydrogen energy in Taiwan

In this study, we extract factors by using factor analysis and then adopt them in a regression analysis to investigate the public perception and acceptance of hydrogen energy in Taiwan. Six reliable factors were extracted from the exploratory factor analysis of 29 5-point Likert-type items. Our regression results show that the public perception of hydrogen energy as a green energy, public belief in domestic hydrogen industries being able to conform to international safety standards, and public perception of the cost advantage of hydrogen gas over petroleum have significantly positive effects on support for the development of hydrogen energy in Taiwan. While people have a high level of concern about the safety of hydrogen and its associated technologies, the unsafe perceptions of hydrogen and its associated technologies have no significant effects on their support. In particular, public belief in domestic hydrogen industries being able to conform to international safety standards is a powerful factor that enhances support for hydrogen energy development.     

Exploring the co-benefits (and costs) of home gardening for biodiversity conservation

ABSTRACT

Despite growing evidence pointing to the multiple benefits of home gardening, few studies have considered the health and well-being benefits perceived by gardeners who are principally motivated by biodiversity conservation (i.e. home gardening for biodiversity conservation). This study explores the environmental, social and economic co-benefits (and costs) of home gardening for biodiversity conservation in the City of Winnipeg, Canada. A total of 42 semi-structured interviews (30–60?min each) were conducted with 50 home gardeners who were formally certified or locally recognised for undertaking multiple gardening activities that promote biodiversity conservation. Thematic analysis revealed that study participants self-reported a range of environmental, psychological, physiological and social outcomes associated with their home gardening experiences. Despite home gardening often being a solitary activity, most gardeners valued the multiple forms of social interaction that occurred during important social events in their garden, or when connecting with passers-by. Home gardeners also cited benefits related to connection to nature and place attachment; attention restoration; reduced stress and anxiety; improved mood; satisfaction and pride; increased self-esteem and courage to do things differently in life; and, important education or learning opportunities. However, conflicts relating to the nexus between biodiversity and perceived tidiness of gardens emerged, which raise important ethical and social justice issues for sustainability planning. We compare key insights to the benefits (and costs) of community gardening and make some recommendations for future research, including how to engage more disadvantaged groups in gardening for conservation.     

Enzymatic degradation of low-rank coals by a cell-free enzymatic system from Coriolus versicolor

An extracellular fraction from the lignin degrading white-rot fungus, Coriolus versicolor, can biosolubilize leonardite and pretreated lignites in vitro. Leonardite is often found as an overburden to lignite deposits, and is related to humic acid, and is more oxidized than lignites. Extracts from certain fungi such as C. versicolor solubilize leonardite. The biosolubilization activity is at least in part enzymatic in nature. A protein which is at least partly responsible for the solubilization effect has been substantially purified and concentrated by ultrafiltration and ion-exchange chromatography from the broth of an agitated submerged culture of C. versicolor grown in a defined medium. An in vitro coal biosolubilization assay was used to establish the effects of various physical and chemical factors affecting enzyme activity, including temperature and the salt and buffer composition of the reaction mixture. Some initial studies on the mechanism of the enzymatic leonardite biosolubilization reaction are described.
