Texte intégralRésumé :
Pro-environmental behavior in addressing climate change is influenced by multi-dimensional factors—knowledge, values, intention and sociodemographic background. Correlational studies between environmental values and environmental behaviors have not been able to determine values or behaviors that need to be given priority in future interventions. Therefore, this study firstly determined the environmental values and pro-environmental behavior that are easy or difficult to embrace by 152 respondents with low socioeconomic background. Secondly, we identified the extent pro-environmental behavior is triggered by environmental values. This survey study employs the Rasch analysis model. The respondents had difficulty in associating themselves with biospheric values however readily demonstrated consideration toward altruistic values, especially related to concerns for future generations. In terms of environmental conservation behavior, the respondents were not willing to relinquish comfort easily, such as giving up self-driving and taking public transportation or reducing usage of electricity. In addition, adults of low socioeconomic background find it difficult to endorse statements such as getting involved in campaigns related to environmental conservation. Thus, younger family members must be educated about conservation behaviors such as environmental campaigns commonly offered at schools, and these youngsters can be encouraged to extend their role by educating their parents.

Texte intégralRésumé :
Appeals to people’s pro-environmental values have been shown to trigger pro-environmental behavior across a range of contexts. The present study tests the potential of such interventions in a hedonic context where behavioral change does not generate utilitarian benefits (tourism). Results from a field experiment in a four-star hotel in Slovenia indicate that appeals to people’s pro-environmental values fail to significantly increase tourists’ hotel towel reuse and decrease room electricity consumption, suggesting that interventions in hedonic contexts—such as tourism—may require the use of more tangible benefits in order to change behavior.

Texte intégralRésumé :
PurposeThe purpose of this paper is to examine in greater depth the influence of internal factors on the disclosure of environmental information by companies. The influence of pro-environmental managers´ personal values on environmental disclosure quality is analyzed and the extent to which the influence of those values is mediated by the practices associated with the environmental organizational structure of the company.Design/methodology/approachThe authors use a partial least squares structural equation model to analyze the relationship between the quality of the environmental information disclosed by 137 environmentally sensitive Spanish firms, their level of commitment towards the environment and the personal values of the directors in charge of those reports.FindingsA central finding of this work is that a positive relationship between the pro-environmental managers’ personal values and environmental disclosure quality is fully mediated by the environmental organizational structures of their companies.Practical implicationsA better understanding of the relationship between the personal values of managers and corporate environmental reporting quality will contribute to the design of policies that can enhance firm transparency and accountability, for example, by educating future managers in sustainability values.Social implicationsLight is cast on the mechanisms that can enhance corporate transparency and accountability in relation to environmental matters.Originality/valueIn this paper, a quantitative study of the internal driving forces of environmental disclosure is conducted, an aspect that has often been ignored in the literature on quantitative voluntary social reporting. The merit of this approach is its contribution to the literature through the analysis of the reasons why powerful actors within firms could (or could not) develop corporate social reporting practices.

Texte intégralRésumé :
An exorbitant rate of resource consumption has created a negative impact on the urban environment. If urban residents fail to behave pro-environmentally, a gradual but sure deterioration of the environment is due in the near future. This study examines the relation between environmental knowledge and pro-environmental behaviour of the residents, with environmental values as the mediator. Survey data was gathered from residents of five large urban neighborhoods in Malaysia. Structural equation modeling is used to analyse the data. Conclusively, environmental knowledge affects the inculcation of environmental values in the residents of urban areas, which in turn affects their pro-environmental behaviour.2398-4295 © 2016.

Texte intégralRésumé :
The study aims to contribute in the understanding of key values and behaviours for Education for sustainable development and their correlations and to further develop knowledge about how they are distributed among upper secondary school students in relation to socio-demographic factors. There were 274 surveys collected in 5 different schools in Ulaanbaatar and analysed using ANOVA followed by Tukey test and Pearson’s correlation tests. The study supports the findings of previous research that universal, benevolence and traditional values are positively correlated with a positive environmental behaviour. The positive orientation towards sustainability suggest that the current adolescent Mongolian population can become potential environmental supporters with a strong motivation towards sustainable behaviour and attitudes. The demographic and social factors were weak in relation to value orientations, no significant difference observed in value orientation. There was a notable gender difference in pro environmental behaviour which aligned with many existing academic studies. Social factors in relation to environmentally friendly attitude suggested that pro environmental adolescents were somehow exposed to the natural environment and read books during their free time displayed increasingly positive behaviour toward the environment. Therefore this study emphasises the importance of encouraging informal outdoor activities and increasing the access and popularity of reading books among youths. These measures would also serve to strengthen the benevolence value and promote pro environmental behaviour.

Texte intégralRésumé :
Contemporary debates about the conservation of natural ecosystems and resources owe most of their influence to the rise of sustainable development, or, sustainability. Since its inception, ‘sustainability’ has become the dominant paradigm for addressing global ecological problems, as well as a strong motivator for changing patterns of behaviour at the level of individual people. The World Commission on Environment and Development (WCED) introduced this framework into global proenvironmental discourse in 1987, and it has since been the source of many debates and discussions within and between academic disciplines. One of the central issues has been the opposition between agency and structure. This is the problem of whether to appeal to agency (theories of individual behaviour change) or structure (theories of social practice) when addressing global environmental problems, as these fields are generally characterised as necessarily opposed to one another. However, each of them at least conceives of a particular kind of agency, meaning that both make an appeal to ‘the individual’ in one way or another. The ultimate aim of this thesis, then, is to reconfigure the way in which individual people are framed by and thus implicated in contemporary discussions about sustainability. In order to do this, I will be drawing heavily on Pierre Bourdieu’s (1984) concept of the ‘cultural intermediary,’ as well as Stuart Hall’s (cf. Grossberg, 1986) theory of ‘articulation.’ I propose a framework that characterises proenvironmental groups as ‘intermediaries,’ as each of these groups acts as a ‘mediator’ or ‘point of articulation’ between the structural dimensions of sustainability and the individual people that they address. I will analyse this framework by appealing to two close studies of two different intermediaries: Greenpeace, and its ‘Save the Reef’ campaign, and Sydney’s Inner West Council, and its ‘Home Eco Challenge.’

Texte intégralRésumé :
Today it has become critical that people adapt their behavior and lifestyles to environmental constraints. Teachers are supposed to teach pupils to accept personal responsibility in regard to these problems. The pedagogies of Waldorf and public schools have different outlooks on nature, hence it was hypothesized that Waldorf and public teachers would differ in regard to pro-environmental behavior and factors explaining such actions. An e-questionnaire measuring pro-environmental behavior, biospheric and altruistic values, feelings of personal responsibility, and pro-environmental attitudes was filled out by 68 Waldorf teachers and 73 public teachers from different municipalities in Sweden. The results suggest that Waldorf teachers report higher biospheric values (partial eta2 = .46, p < .001), more pro-environmental behavior (partial eta2 = .39, p < .001), more feelings of personal responsibility, (partial eta2 = .32, p < .001), and higher altruistic values (partial eta2 = .12, p < .001), than public school teachers do. There were a few limitations in reliability and possibly with social desirability. However, the present study paves the way for an understanding of how pedagogy can be of help in preventing further environmental problems.

Boomsma, Christine. « Visual images as a motivational bridge to pro-environmental behaviour : a cognitive approach ». Thesis, University of Plymouth, 2013. http://hdl.handle.net/10026.1/1546.
Texte intégralRésumé :
Communicating climate change and other long-term environmental issues to the wider public is a challenging process involving many barriers to action. Visualisations have the ability to overcome these barriers. Furthermore, the benefits of visual images over verbal information have been supported. However, there is a lack of research on how visual images can motivate behaviour. Based on Elaborated Intrusion theory, it is proposed that visual images can be internalised as mental images which can act as a ‘motivational bridge’ for pro-environmental behaviour. Six studies exposed participants to visual pro-environmental messages. Throughout all studies images were internalised as mental images, associated with intrusive thoughts. Consistently, mental images were strongly associated with pro-environmental goals and behaviour change (self-report and actual). Also, interfering with visual mental imagery, using cognitive tasks, reduced self-reported behaviour change (Study 6). Overall, two motivational roles of mental imagery emerged: mental images can trigger pro-environmental goals and can strengthen the relationship between pro-environmental goals and behaviour. The development, strength, and vividness of mental imagery depended on interacting individual and message characteristics. A vivid message was more effective when the message topic was relevant to the target individual (Study 2). Also, a message in line with existing values evoked more vivid mental imagery (Studies 2 to 6). A message could activate specific values as well if mental imagery was not interfered with (Study 5 and 6). And finally, positive and negative images were associated with different feelings, but could both be internalised and motivate behaviour (Study 3 and 6). A combined message could overcome the negative feelings associated with a fear appeal (Study 6). This thesis developed a theoretical framework, integrating approaches from social and cognitive psychology, which can help explain and predict responses to visual environmental messages. Six studies showed that the effect of a visual image on behaviour depends, among other factors, on its ability to trigger recurring mental imagery. Insights provide opportunities for designing evidence based visual pro-environmental messages. In turn this can maximise the impact visual messages have on changing people’s pro-environmental behaviour.

Texte intégralRésumé :
Le condizioni in cui versa il nostro pianeta sono sempre più gravi: sembra emergere in modo piuttosto evidente la responsabilità umana in relazione ai cambiamenti climatici e ambientali a livello planetario. Tale responsabilità assume almeno due aspetti principali: da un lato, rispetto a quelle visioni del mondo, della natura e dell’ambiente che hanno orientato le scelte, le decisioni e i comportamenti umani nei confronti dell’ambiente naturale; dall’altro, rispetto alla responsabilità, alla quale il genere umano è chiamato, di operare in maniera tale da interrompere il ciclo di sfruttamento e distruzione, compiendo una vera e propria ‘inversione di rotta’. La progressiva comparsa di nuove e sempre più forti crisi ambientali richiama alla necessità di focalizzarsi sulla relazione tra esseri umani e natura e sui valori che sono alla base di tale relazione. Dalla fine degli anni ’60 del secolo scorso quando iniziò a manifestarsi la crisi ambientale, si può notare come la filosofia abbia rivolto la sua attenzione, in maniera sempre maggiore, alla relazione tra esseri umani e natura, cercando di individuare le cause dei problemi ecologici. La riflessione filosofica su tale relazione si colloca all’interno della più ampia riflessione dell’etica ambientale, che nel corso della storia del pensiero umano ha esteso sempre di più il proprio campo d’interesse, attraverso la metafora del “cerchio morale di espansione”, ampliandolo sia dal punto di vista temporale, includendo le generazioni future, sia dal punto di vista spaziale, includendo dapprima il mondo degli animali non-umani e, in seguito, anche l’ambiente e i sistemi viventi. Diversi studi internazionali in questo campo sono stati condotti, con differenti gruppi etnici, a livello nazionale e cross-national. Non sembrano, tuttavia, essere presenti degli studi che abbiano esplorato i punti di vista sulla natura e l’ambiente di soggetti provenienti da diversi gruppi etnici immigrati in un singolo stato, utilizzando approcci qualitativi o Mixed Methods, senza compiere delle comparazioni tra le diverse culture. Restando all'interno della prospettiva delle Etiche dell’ambiente, fondata sulla rilevanza che hanno i valori e le visioni del mondo nell'orientare i comportamenti umani, gli obiettivi della presente ricerca sono di esplorare la relazione tra gli esseri umani, l’ambiente naturale e gli animali non umani, i punti di vista e i significati attribuiti alla natura e alcune dimensioni concernenti i valori ambientali, i comportamenti in favore dell’ambiente e la consapevolezza dell’esistenza dei problemi ecologici. Il presente studio è volto a comprendere il punto di vista degli immigrati in Italia, a conoscere alcuni aspetti della loro cultura relativamente ai temi ambientali e alla sostenibilità, attraverso le loro narrazioni individuali, con l'intento di contribuire a una comprensione generale della relazione tra esseri umani e ambiente naturale e a gettare luce su alcuni aspetti inesplorati nella popolazione immigrata in Italia, relativamente a tale relazione. L’attenzione si è rivolta verso soggetti appartenenti a diversi gruppi etnici, immigrati in Italia e il gruppo dei partecipanti è stato individuato principalmente tramite delle associazioni d’immigrati in due aree: Milano, Parma e le rispettive province. Soggetti adulti, di diversi gruppi etnici, immigrati in Italia come prima generazione sono stati coinvolti nella ricerca come gruppo di partecipanti. In considerazione del fatto che lo scopo dello studio non è quello di ottenere risultati quantitativi su larga scala ma, piuttosto, quello di condurre un’analisi approfondita del pensiero individuale, si è scelto di utilizzare un approccio Mixed Methods, attraverso uno strumento quantitativo composto da una sezione di domande strutturate con risposta multipla su scala Likert, affiancato ad una intervista qualitativa. La sezione quantitativa ha preso ispirazione da precedenti studi quantitativi, principalmente condotti in ambiti psicologici, sociologici, economici, basati sull'utilizzo di scale volte a rilevare i valori ambientali e i comportamenti in favore dell’ambiente. L’intervista qualitativa è stata elaborata con l’intento di promuovere la narrazione delle esperienze dei rispondenti, a partire dai loro contesti di vita originari, relativamente alla loro relazione con l’ambiente naturale e gli animali nel loro paese d’origine e in Italia. Le narrazioni raccolte hanno contribuito a un arricchimento culturale grazie allo sguardo molteplice proveniente da diverse culture, focalizzato sulla relazione tra esseri umani, natura e animali a mostrare alcuni aspetti non ancora esplorati nella popolazione immigrata in Italia, relativamente a tale relazione.The Planet Earth has entered into the Anthropocene Era, scientist J.P.Crutzen said. It’s the Era of human beings, distinguished from the previous ones by the impact that humans are having on the climate and planetary environment. It’s rather clear that human responsibility is strongly implicated in the planetary changes. This responsibility takes at least two main aspects. On the one hand, with respect to those visions of the world, the nature and the environment that have guided the choices, the decisions and the human behavior towards nature and the environment. On the other, regarding the responsibility to which the mankind is called, in working to stop the cycle of exploitation and destruction, and make a real 'change of direction'. The emergence of new and increasingly strong environmental crisis emphasizes the need to focus on the relationships between humans and nature and the values underpinning them. Since the '70s, with the emergence of the environmental crisis, philosophy has increasingly turned its attention towards the relationship ‘humans-nature’. Philosophy reflection is inscribed within the Environmental Ethics perspective that has gradually extended its field of interest, through the metaphor of the "moral circle expansion", widening temporally, including future generations, and spatially, including the world's non-human animals and the environment, understood as ecosphere and biosphere. Several international studies in this field were conducted with different ethnic groups at a national and at cross-national level. No studies were found aiming to investigate immigrants’ world views on nature and environment conducted through a qualitative and/or mixed method approach with key respondents belonging to different ethnic groups, immigrated into a single state, without a comparison among cultures. Inside the Environmental Ethics’ perspective, grounded on the relevance of humans’ values and world vision guiding their behaviours, the research objects aims to explore the relationships between humans, natural environment and non-human animals, people’s worldviews on nature and the importance they confer to it and some dimensions related to environmental values, pro-environmental behavior and environmental problems awareness. This study aims to understand the views of immigrants in Italy, some aspects of their culture in relation to environmental issues and sustainability, through their individual stories, with the intent to contribute to a general understanding of the relationship between human beings and the natural environment, casting a light on some unexplored aspects of the immigrant population in Italy, with regard to such a relationship. With the above aims in mind, the attention was focused on people from different ethnic groups immigrated to Italy and the purposefully selected group of respondents was sought gathering people from Immigrants Associations in two areas: Milano, Parma and their provinces, where these associations are widespread and usually promote integration through their activities and initiatives. Foreign adults, from different ethnic groups, immigrated to Italy as first generation were selected as key respondents. Considering that the study aim is not to obtain quantitative results on a large scale but it is an in depth analysis of individual thinking, a mixed methods approach, composed by a quantitative tool consisting of a structured interview with multiple choice answers on Likert scale along with a qualitative interview, was elaborated.

Texte intégralRésumé :
While studies indicate there is a strong link between pro-environmental values and behaviour, they also show that such values are not necessarily enacted consistently across all areas of our lives. There are many psychosocial factors that can affect congruent enactment. Improving our understanding of what these factors are and how they influence cognition and behaviour is critical for subverting our inadequate response to ecological crisis, yet it is an area that remains under explored. In this thesis I investigate factors affecting enactment of pro-environmental values by individuals in organisational contexts. Integrating Interpretative Phenomenological Analysis with frame and metaphor analysis in an innovative transdisciplinary and cross-level methodology, my study enquires into the lived, embodied and situated experience of six sustainability managers and leaders in the UK and Canada in their work to influence pro-environmental practices in their organisations. Using semi- structured interviews as the primary data source, over 70 highly nuanced and in-depth findings are generated, enriching our understanding of psychological threat coping strategies from a systemic perspective: • Sources of threats and tensions that arise for sustainability managers in their work to influence organisational practices (e.g. thwarted autonomy, competency or relatedness needs, incongruence in values) • Types of coping strategies used to negotiate these tensions (including identity work, emotion regulation, seeking support from external partners, constructing a motivational story, nature connection) • Ecologically adaptive and maladaptive outcomes of these responses for the individual and the organisation (including indirect impacts on vitality and effectiveness) • Factors affecting the efficacy of adaptive coping strategies (e.g. type of motivation, type of self-awareness, cognitive frames about nature) • Contextual factors (organisational, cultural worldview) • How these factors interact with each other, creating feedback loops The conceptual models I have constructed make these largely unconscious psychosocial processes visible; and may be of practical use to individuals in facilitating deeper awareness of the dynamics in their situation and helping to identify where interventions can be made to improve their efficacy and resilience in influencing pro-environmental change in their organisations.

Texte intégralRésumé :
A adoção de práticas sustentáveis desde à produção de alimentos até o consumo final tem sido mais frequente nos últimos anos. Essas práticas sustentáveis estão embasadas na promoção do desenvolvimento sustentável, sem prejudicar as gerações futuras da humanidade. Nesse contexto, os proprietários das agroindústrias familiares se deparam com diversos desafios quando se trata da diminuição de impactos ambientais e, em consequência, da promoção do desenvolvimento rural sustentável. A adoção de práticas sustentáveis é resultado da compreensão da consciência ambiental e dos valores humanos, os quais desencadeiam as atitudes pró-ambientais e, assim, resulta em um comportamento ecológico. Neste sentido, objetivou-se analisar a influência da consciência ambiental e dos valores humanos sobre as atitudes pró-ambientais dos proprietários das agroindústrias familiares vinculadas ao PEAF/RS. Os dados foram coletados por meio da aplicação de questionário, com quatro grupos de questões (perfil das agroindústrias familiares e atitudes pró-ambientais, Escala NEP, perfil socioeconômico, Escala Schwartz). A amostra corresponde aos 105 proprietários de agroindústrias familiares do Rio Grande do Sul. Os dados foram analisados utilizando estatística descritiva, analise fatorial e correlação. Os resultados apresentam que mais da metade da amostra é composta por adultos, com grau de escolaridade elevado e com formação em cursos voltados para a gestão da agroindústria Além disso, 37% das agroindústrias familiares têm um tempo de existência entre um a cinco anos, com mão de obra familiar e com atividades predominantes em olericultura, bebidas e panificados, nas cidades de Caxias do Sul, Santa Maria e Lajeado. A aplicação das escalas, demonstrou que os proprietários das agroindústrias familiares possuem um nível elevado de consciência ambiental, com predominância nos valores humanos de ordem superior “conservação” e “autotranscendência”. Tais resultados revelam uma tendência de possuir um comportamento ecocêntrico e altruísta, conforme a Escala NEP e Schwartz, respectivamente. Além disso, observou-se que as agroindústrias familiares têm atitudes pró-ambientais, as quais são implantadas e praticadas pela agroindústria. De modo geral, 40% dos proprietários das agroindústrias acreditam que o empreendimento tem mais de 80% de atividades pró-ambientais, tais como, o uso de embalagens recicláveis, a prática de conscientização ambiental, a economia de energia, o uso correto do descarte dos resíduos sólidos. Porém não foi encontrado correlação entre as escalas e as atitudes pró-ambientais. Portanto, entende-se que esses resultados auxiliam as esferas federativas na formulação de uma política de benefícios, motivando-os aqueles que possuem mais adequação à preservação ambiental e incentivando outros proprietários a praticarem mais ações ambientais.The adoption of sustainable practices from food production to final consumption has been more frequent in recent years. These sustainable practices are based on the promotion of sustainable development, without harming future generations of humanity. In this context, the owners of family agroindustries face several challenges when it comes to reducing environmental impacts and, as a consequence, promoting sustainable rural development. The adoption of sustainable practices is the result of an understanding of environmental awareness and human values, which triggers pro-environmental attitudes and thus results in ecological behavior. In this sense, the objective was to analyze the influence of environmental awareness and human values on the pro-environmental attitudes of the owners of family agroindustries linked to PEAF/RS. Data were collected through the application of a questionnaire, with four groups of questions (profile of family agroindustries and pro-environmental attitudes, NEP Scale, socioeconomic profile, Schwartz Scale). The sample corresponds to the 105 owners of family agroindustries in Rio Grande do Sul. Data were analyzed using descriptive statistics, factorial analysis and correlation. The results show that more than half of the sample is composed of adults, with a high level of education and training in courses aimed at the management of agribusiness. In addition, 37% of family agroindustries have a life span of between one and five years, with family labor and predominant activities in olericultura, beverages and baked goods, in the cities of Caxias do Sul, Santa Maria and Lajeado The application of the scales, showed that the owners of the family agroindustries have a high level of environmental awareness, with a predominance of human values of higher order "conservation" and "self-transcendence". These results reveal a tendency to have an ecocentric and altruistic behavior, according to the NEP and Schwartz Scales, respectively. In addition, it was observed that family agroindustries have pro-environmental attitudes, which are implemented and practiced by the agroindustry. In general, 40% of the owners of agroindustries believe that the enterprise has more than 80% of pro-environmental activities, such as the use of recyclable packaging, the practice of environmental awareness, energy saving, the correct use of waste of solid waste. However, no correlation was found between the scales and the pro-environmental attitudes. Therefore, it is understood that these results help federative spheres in the formulation of a benefits policy, motivating those that are more adequate to environmental preservation and encouraging other owners to practice more environmental actions.

Texte intégralRésumé :
This chapter focuses on the well-documented misalignment between energy-related behaviors and the personal values of consumers, which has become a major source of angst among policymakers. Despite widespread pro-environmental or green attitudes, consumers frequently purchase non-green alternatives. The chapter identifies 50 theoretical approaches that can be divided almost equally into two types: those that emphasize beliefs, attitudes, and values; and those that also consider contextual factors and social norms. Three principles of intervention are recommended: provide credible and targeted information at points of decision; identify and address the key factors inhibiting and promoting the target behaviors in particular populations; and rigorously evaluate programs to provide credible estimates of impact and opportunities for improvement. The chapter recommends that research on the value-action gap be expanded beyond the traditional focus on individuals to include decision-making units such as households, boards of directors, commercial buying units, and government procurement groups.

Texte intégralRésumé :
Schizophrenia, Parkinson’s disease, and attention deficit hyperactivity disorder (ADHD) discusses how hyperactive dopaminergic neurotransmission appears to underlie schizophrenia’s positive symptoms, loss of dopaminergic neurons in adulthood leads to Parkinson’s disease, and dopamine neuron hypofunction in childhood and adolescence may underlie ADHD. Positive schizophrenia symptoms may arise from excessive incentive learning that is gradually lost with antipsychotic treatment. Declarative learning and memory may contribute to delusions based on excessive incentive learning. Loss of responsiveness to environmental stimuli in Parkinson’s may result from a decrease of their conditioned incentive value and inverse incentive learning. Conditioned incentive stimuli not encountered while in a state of decreased dopaminergic neurotransmission may retain their incentive value, producing apparent kinesia paradoxa. Dopamine hypofunction in juveniles does not lead to hypokinesia but may result in loss of incentive learning that focuses attention. Pro-dopaminergic drugs have a calming effect in ADHD, presumably because they reinstate normal incentive learning.

Texte intégralRésumé :
AbstractThis chapter focuses on the question of why environmentally conscious individuals find it difficult to behave in a correspondingly eco-friendly way. This phenomenon is referred to in the literature as the “value-action gap.” In this study, the definition of this gap is further expanded by considering individual intention. The discrepancies between environmental values, intention, and behavior are explored in the context of two environmentally relevant behaviors—mobility and consumption—using qualitative interviews. Firstly, key structural and intrapersonal obstacles to pro-environmental behavior are identified. Secondly, individual needs and requirements for facilitating eco-friendly behavior are addressed. Finally, strategies and potentials for pro-environmental change in society are discussed.

Texte intégralRésumé :
AbstractThis chapter explores individual incentives and barriers to reducing air travel, with the focus on people who have taken a decision to reduce flying due to climate change. During the COVID-19 pandemic in 2020, six semi-structured interviews were performed with academics—three who had already cut down on flying and three who were grounded due to the pandemic. They were compared with a set of interviews with 26 Swedish citizens, performed in 2017–2018, which had shown that internalised knowledge of climate change was an important driver to change behaviour. Awareness led to negative emotions and a personal tipping point where a decision to reduce flying was made. However, among these interviewees, even people with a strong drive to reduce flying felt trapped in practices, norms and infrastructures. The academics reported similar incentives and barriers as the broader group but also specific challenges for them as researchers. Surprisingly, the pandemic was perceived as a testbed for new travel habits, and not as a big obstacle for their scientific work. None believed that they would return to an equally aeromobile lifestyle, and two of them described it as a chance to reconcile habits with their pro-environmental values.

Texte intégralRésumé :
Abstract Self-determined pro-environmental motivation is arguably the most important motivational resource for protecting the environment and supporting a sustainable lifestyle. At the same time, pro-environmental behavior evolves from multiple goals, values, and cues beyond self-determined motivation. This chapter reviews the state of research on self-determination and values as they relate to pro-environmental behavior. It sketches a framework to promote more widespread pro-environmental behavior by integrating motivation, values and goals, and social support. By understanding the manner in which values and motivation interact in predicting pro-environmental behavior, it becomes possible to identify sources of motivational conflict that lead to environmentally unsound choices. Through a process of aligning individuals’ values and motivation, strategies for intervention begin to emerge.

Texte intégralRésumé :
The Christian Churches’ traditional environmental ethic is stewardship. Laudato si’ (2015) has augmented stewardship ethics with an ethics of care. The ethics of care is also the one that inspires Francis of Assisi and Bonaventure, indigenous people and feminist ethics. Laudato si’ puts a major emphasis on education and pays scant attention to policy because deep changes allegedly need to occur first at the individual level. Policy toward global ecological problems has been difficult to formulate and implement because the latter are public goods “wicked problems”. Some policy experts, in their respective reviews of U.S. climate policies, tend to fall back on ethics rather than policy as a major motivator for appropriate individual behavior, comforting pope Francis’ conviction. The relatively recent ethics of relational values may be a useful tool to build bridges among different types of ethics. Could religion, any religion, be an alternative motivator for pro-environmental behavior? Abundant sociological analysis concludes to the contrary. Eco-theology is creation theology that has been shaped by environmental problems. Its summary provided here in point form offers the potential for becoming a mobilizing “grand-narrative”. However, it is still in its infancy and does not have a unified methodology yet.

Texte intégralRésumé :
In the 21st century, the Sustainable Developmental Goals have become the pivot of economic development worldwide. Hence, the need to promote sustainability-oriented entrepreneurial behaviour has increased manifold. Intentions are assumed to capture the motivational factors that influence an individual's behaviour. Thus, behavioural intentions play a significant role in bridging the gap between sustainable development and sustainable entrepreneurial behaviour. This study aims at understanding the role of intrinsic rewards in shaping the sustainability-oriented entrepreneurial intentions of individuals. The case study method is adopted to understand and validate the theories referred. The sub-constructs of intrinsic rewards like altruism, socio-emotional feelings, pro-environmental values, autonomy, and community feeling aspirations were found to drive the sustainability-oriented entrepreneurial intentions of an individual. Lack of awareness of the structural environment support was highlighted as a hindrance in fostering the sustainable entrepreneurship ecosystem in the Indian economy.

Texte intégralRésumé :
Otimizar o consumo de espaço e recursos naturais é uma meta recomendável para atingir maior sustentabi-lidade urbana, assim como racionalizar e gerenciar eficientemente os fluxos urbanos. O presente artigo apresenta uma etapa de uma pesquisa no campo do Desenho Urbano que questiona como se configuram os espaços do entorno de terminais de ônibus. O objetivo é refletir sobre resultados e consequências de projetos urbanos (urban design), principalmente aqueles que afetam parcelas significativas da população, como as condições de mobilidade em centros metropolitanos. Curitiba é pólo de uma região metropolitana formada por 29 municípios, sendo que 13 deles são abrangidos pelo sistema de transporte integrado RIT, que transporta diariamente cerca de 2 milhões de usuários. A justificativa para o estudo deriva da ampliação do sistema RIT em face à expansão periurbana, limitações ambientais e otimização do uso do solo urbani-zado. A metodologia é de pontuação por categorias de elementos existentes e escala de valores, como primeira etapa para obter indicadores para gestão ambiental urbana. Optimizing the occupation of space and the use of natural resources is a recommended goal in order to achieve greater urban sustainability, and so is rationalizing and managing efficiently urban flow. This article presents a step of a research in the field of Urban Design that questions how are urban spaces configured in the surroundings of bus stations. The objective is to reflect about results and consequences of urban pro-jects (urban design), especially those affecting a significant part of the population, such as mobility condi-tions in metropolitan centers. Curitiba is the pole of a metropolitan area composed by 29 municipalities, but 13 of them comprised by the integrated transportation system known as RIT, which transports approximately 2 million users daily. The study is justified by the upcoming extension of the RIT system in face of peri-urban growing, environmental limits and the balance for urbanized soil needs. The methodology is of punctuating per categories existing elements and scales of values as first stage as to obtain pointers to manage the ur-ban environment.

Texte intégralRésumé :
For development strategic planning in urban areas, it is important to take into account, that the area is not homogenous in terms of economic, social or environmental. Ensuring fair authority’s approach is crucial for sustainable development of the area. An environmental quality index for city districts of Brno is proposed in this study. The aim of this study is to create an index, which uses public data and enables identification of city districts, which show higher vulnerability to environmental injustice. Employing GIS, data, which represent both environmental benefits, such as green and blue infrastructure, as well as environmental burden, e. g. air pollutants and noise level, was processed. Then the composite indicator was constructed. The case study showed that two basic areas can be distinguished within the city of Brno. In the northern part, urban areas with higher index values are clustered, which shows that the environmental benefits outweigh the burden. On the other hand, in the south there are city districts with a lower index value. This means that the environmental burden here is high and is not balanced by environmental benefits, which is a cause of an overall deterioration of amenities of the local population. Thus, a higher risk of environmental injustice can be identified here.

Texte intégralRésumé :
The climate crisis has received high levels of attention from the public and scholars over the last few decades. While the search for solutions involves strict regulations and innovation in clean energy sources, changing individual behaviours towards sustainability could prevent us from reaching a point of no return. Inarguably, there is a need for strong involvement of the public and private sector organizations, changing individual organizational behaviours towards sustainability might foster a great impact in terms of lowering the effects of the climate crisis. In this context, a democratic pro-environmental behaviour (DPEBs) is introduced to enable green behaviours with individual and voluntary actions within organizations that benefit the preservation and recovery of the environment. Recycling, efficient energy consumption, reduction of meat consumption and sustainable transportation are examples of actionable PEBs that need to be fostered to contribute to the reduction of the human impact on climate change.Nevertheless, the adoption of new behaviours is a complex goal that requires the application of mechanisms to address employee intrinsic and extrinsic democratic motivation. In this vein, gamification, as a process that enhances projects and service with affordances for gameful experiences., might provide a viable alternative. The purpose of this paper is to analyse the extent to which gamification is an effective alternative to promote the adoption of democratic pro-environmental behaviours and contribute to the creation of the relative organization culture. The accepted definition of gamification for this paper is the process of enhancing a service with affordances for gameful experiences in order to support user's overall value creation. This marketing perspective approach, has more focus on the effects obtained as a consequence of activating intrinsic and extrinsic motivation through the use of gamified systems rather than the analysis of the characteristics of the game design elements, and the incentives for its practical and actual adaptation and utilization within organizations.A systematic literature review was conducted in order to exclusively retrieve - after a thorough selection process - case studies that evaluated the psychological and behavioural effects of gamified information technology systems. Psychological outcomes are related to intrinsic motivation; in the case of gamification, positive outcomes are described by gameful experience. These, in turn, are categorized in this work according to the motivational need to which they correspond and their adaptation likeness in a corporate context. On the other hand, behavioural outcomes are related to extrinsic motivation; these are the desired pro-environmental behaviours promoted extrinsically with the use of the gamified application.Fifteen studies were analysed in detail, which overall provided positive results regarding gamification’s capability to engage users by appealing to intrinsic motivation and to effectively promote the adoption of extrinsically motivated PEBs. As a result the paper presents a methodological approach and a process model that integrates democratic organizational culture elements that utilize gamification to achieve employee pro-environmental behaviours that can benefit both the economy and the society. Furthermore the proposed model is linked with the ESG criteria as a further incentive for its organization adaptation from theory to practice. The paper also indicates limitations and areas of further research on the proposed model towards green ocean strategies that can maximize its applications and impact.

Texte intégralRésumé :
Abstract Nutrient film technology-based hydroponic systems are hydrophilic. Hence, a constant water supply is essential for the optimal yield and viability of the investment. Though the national grid could power water pumps for a hydroponic system in urban areas, incessant load shedding in South Africa has significantly affected the yield. Hence, the need for an alternative power supply for these systems. This study conducted a techno-economic analysis on a proposed solar photovoltaic (PV) for a hydroponic food garden located in Johannesburg. The case study constitutes one of the Urban Agricultural Initiatives (UAI) in the city. The optimal solar-PV sizing for the hydroponic system was developed. Two scenarios for powering the hydroponic system were investigated vis-à-vis the standalone solar-PV and national grid with solar-PV and battery backup. Among other cost functions, the levelized cost of electricity (LCOE) was used to evaluate the systems. The simulations were performed using HOMER Pro tool for Microgrid Analysis to determine the profitability of the two alternative energy sources on the system. Among the two alternatives, the hybrid system offered a lower net present value (NPV) of 79, 156.74 (ZAR) and an LCOE of 0.47 (ZAR) compared with the standalone system with an NPV of 290,930.73 (ZAR) and an LCOE of 2.57 (ZAR). However, the indirect value chain of the hybrid solution is associated with environmental emissions. The results obtained from the two scenarios could be used as a model for powering other urban hydroponic systems in other geospatial locations. While system effectiveness is highly prioritized, an economical scenario that mitigates the load shedding effects and enhances the productivity of the hydroponic food garden is very vital.

A Quantitative Study of Doctoral Candidates in Australia ». Dans InSITE 2022 : Informing Science + IT Education Conferences. Informing Science Institute, 2022. http://dx.doi.org/10.28945/4912.
Texte intégralRésumé :
Aim/Purpose This paper investigates the association between publishing during doctoral candidature and completion time. The effects of discipline and of gaining additional support through a doctoral cohort program are also explored. Background Candidates recognize the value of building a publication track record to improve their career prospects yet are cognizant of the time it takes to publish peer-reviewed articles. In some institutions or disciplines, there is a policy or the expectation that doctoral students will publish during their candidature. How-ever, doctoral candidates are also under increasing pressure to complete their studies within a designated timeframe. Thus, some candidates and faculty perceive the two requirements – to publish and to complete on time – as mutually exclusive. Furthermore, where candidates have a choice in the format that the PhD submission will take, be it by monograph, PhD-by-publication, or a hybrid thesis, there is little empirical evidence available to guide the decision. This pa-per provides a quantitative analysis of the association between publishing during candidature and time-to-degree and investigates other variables associated with doctoral candidate research productivity and efficiency. Methodology Multivariate logistic regression analyses were used to examine the predictors (discipline [field of research], gender, age group, domestic or international student status, and belonging to a cohort program) of doctoral candidate research productivity and efficacy. Research productivity was quantified by the number of peer-reviewed journal articles that a candidate published as a primary author during and up to 24 months after thesis submission. Efficacy (time-to-degree) was quantified by the number of Full-Time Equivalent (FTE) years of candidature. Data on 1,143 doctoral graduates were obtained from a single Australian university for the period extending from 2000 to 2020. Complete publication data were available on 707 graduates, and time-to-degree data on 664 graduates. Data were drawn from eight fields of research, which were grouped into the disciplines of health, biological sciences, agricultural and environmental sciences, and chemical, earth, and physical sciences. Contribution This paper addresses a gap in empirical literature by providing evidence of the association between publishing during doctoral candidature and time-to-degree in the disciplines of health, biological sciences, agricultural and environmental sciences, and chemical, earth, and physical sciences. The paper also adds to the body of evidence that demonstrates the value of belonging to a cohort pro-gram for doctoral student outcomes. Findings There is a significant association between the number of articles published and median time-to-degree. Graduates with the highest research productivity (four or more articles) exhibited the shortest time-to-degree. There was also a significant association between discipline and the number of publications published during candidature. Gaining additional peer and research-focused support and training through a cohort program was also associated with higher research productivity and efficiency compared to candidates in the same discipline but not in receipt of the additional support. Recommendations for Practitioners While the encouragement of candidates to both publish and complete within the recommended doctorate timeframe is recommended, even within disciplines characterized by high levels of research productivity, i.e., where publishing during candidature is the “norm,” the desired levels of student research productivity and efficiency are only likely to be achieved where candidates are provided with consistent writing and publication-focused training, together with peer or mentor support. Recommendations for Researchers Publishing peer-reviewed articles during doctoral candidature is shown not to adversely affect candidates’ completion time. Researchers should seek writing and publication-focused support to enhance their research productivity and efficiency. Impact on Society Researchers have an obligation to disseminate their findings for the benefit of society, industry, or practice. Thus, doctoral candidates need to be encouraged and supported to publish as they progress through their candidature. Future Research The quantitative findings need to be followed up with a mixed-methods study aimed at identifying which elements of publication and research-focused sup-port are most effective in raising doctoral candidate productivity and efficacy.

Texte intégralRésumé :
Habitat suitability models are widely adopted in ecosystem management and restoration, where these index models are used to assess environmental impacts and benefits based on the quantity and quality of a given habitat. Many spatially distributed ecological processes require application of suitability models within a geographic information system (GIS). Here, we present a geospatial toolbox for assessing habitat suitability. The Geospatial Suitability Indices (GSI) toolbox was developed in ArcGIS Pro 2.7 using the Python® 3.7 programming language and is available for use on the local desktop in the Windows 10 environment. Two main tools comprise the GSI toolbox. First, the Suitability Index Calculator tool uses thematic or continuous geospatial raster layers to calculate parameter suitability indices based on user-specified habitat relationships. Second, the Overall Suitability Index Calculator combines multiple parameter suitability indices into one overarching index using one or more options, including: arithmetic mean, weighted arithmetic mean, geometric mean, and minimum limiting factor. The resultant output is a raster layer representing habitat suitability values from 0.0 to 1.0, where zero is unsuitable habitat and one is ideal suitability. This report documents the model purpose and development as well as provides a user’s guide for the GSI toolbox.
