Why do people participate in monitoring the effects of natural resource harvest and trade? Assessing multiple drivers of participation. / Por que os povos da floresta se envolvem no monitoramento participativo da coleta e do comércio de recursos naturais? Avaliando múltiplos determinantes da participação

Brites, Alice Dantas 03 March 2015 (has links)
Participatory monitoring of ecological and socioeconomic effects of harvesting and trading natural resources is advocated as a promoter of natural resource conservation and local communitiy empowerment. Nevertheless, the strategys success depends upon peoples willingness and availability to participate. Yet little is known about the factors that drive local communities to volunteer in participatory monitoring, particularly in relation to small-scale communities living in remote locations. This thesis investigated whether a number of candidate factors were able to predict peoples participation in monitoring. To do so, we conducted a study in a forest community of the Brazilian Amazon that harvested and traded Carapa guianensis (andiroba), a non-timber forest product (NTFP). Two methods of data gathering were employed: (i) an interview-based survey of 166 adults ( 18 y.o.; 51 households) to estimate peoples self-stated intention to participate and the drivers of their participation, and (ii) experimentally-implemented monitoring tasks of the effects of harvesting and trading C. guianensis to measure peoples actual participation. Results are presented in three chapters. In Chapter 1, we evaluated whether economic benefits received from the NTFP trade or, alternatively peoples cooperativeness, were more important in predicting peoples participation. Results indicated that both variables raised peoples intention and actual levels of participation in monitoring, but cooperativeness was a stronger and better predictor across monitoring tasks. In Chapter 2, we investigated the psychology of engaging in monitoring, departing from the theoretical framework of the Theory of Planned Behavior (TPB) for understanding whether the variables in the model were appropriate to predict the willingness to volunteer in monitoring tasks. We found that the TPB model, in general, was able to predict peoples intention to volunteer in monitoring tasks. Specifically, one of the attitude indicators (attitude pleasure) explained the intention to engage in all monitoring tasks assessed. Subjective norms were also important to predict the intention to collect data on natural resource populations and to interview community inhabitants, whereas perceived behavioral control predicted the intention to collect data on natural resources and to deal with data management and storage. Finally, in Chapter 3 we hypothesized that the awareness of ecological and socioeconomic impacts of NTFP harvest and trade should explain peoples participation in monitoring. Results indicated that both factors were important, particularly regarding to peoples actual participation, although factors such as gender, age and schooling were occasionally stronger predictors. Nevertheless, there is evidence that combining monitoring of ecological and socioeconomic factors will boost the practices success. The study conclusions contribute to lessons aimed at stimulating participation in monitoring. Among those, we highlight the importance of strategies to increase levels of cooperativeness among people, spreading information about the possible negative effects of natural resource harvest and trade, and granting financial compensations equivalent to the opportunity costs of participation. / O monitoramento participativo dos efeitos ecológicos e socioeconômicos da coleta e do comércio de recursos naturais é uma estratégia considerada promotora tanto da conservação ambiental, quanto do empoderamento das comunidades locais. O sucesso da estratégia, todavia, depende, sobretudo, da disponibilidade e disposição dos indivíduos em participarem. Apesar disso, sabe-se pouco sobre os fatores que determinam a participação voluntária no monitoramento, especialmente em comunidades de pequena escala habitantes de áreas remotas. Sendo assim, esta tese teve por objetivo investigar o efeito de determinantes da participação no monitoramento. Para tal, foi estudada uma comunidade da Amazônia brasileira que coleta e comercializa Carapa guianensis (andiroba), um produto florestal não madeireiro (PFNM). Dois métodos de coleta de dados foram utilizados: (i) survey por meio de entrevistas a 166 adultos ( 18 anos; 51 unidades domésticas) para estimar a intenção de participar e os determinantes da participação, e (ii) implementação de monitoramento experimental dos efeitos da coleta e do comércio de C. guianensis para quantificar a participação real no monitoramento. Os resultados são apresentados em três capítulos. No Capítulo 1, avaliamos se os benefícios econômicos obtidos com o comércio de PFNM ou, alternativamente, o comportamento cooperativo são determinantes mais importantes da participação. Os resultados indicaram que as duas variáveis aumentam a intenção e a participação real no monitoramento. Porém, o comportamento cooperativo foi um indicador mais forte da participação entre as diferentes atividades de monitoramento avaliadas. No Capítulo 2, investigamos os fatores psicológicos que afetam a participação, utilizando como base a Teoria do comportamento planejado (TCP) e avaliando o efeito das variáveis deste modelo sobre a probabilidade da participação voluntária no monitoramento. Os resultados indicaram que, em geral, o modelo da TCP é adequado para prever a intenção de participar em diferentes etapas do monitoramento avaliadas. Em particular, um dos indicadores de atitude (prazer) é capaz de explicar a participação nas quatro etapas de monitoramento. Normas subjetivas também foram importantes preditores da intenção de participar da coleta de dados da população de andiroba e entrevistar outros moradores da comunidade. Já o controle comportamental percebido previu a intenção de participar da coleta de dados sobre a população do recurso natural e a entrada e armazenamento de dados. No Capítulo 3, partimos da hipótese de que a percepção dos impactos ecológicos e socioeconômicos da coleta e do comércio de PFNM pode explicar a participação no monitoramento. Os resultados indicaram que a percepção dos dois tipos de impactos é importante, sobretudo para a participação real. Porém, outros fatores como gênero, idade e escolaridade são determinantes mais fortes da participação em algumas atividades. Ademais, encontramos evidências de que aliar o monitoramento de impactos ecológicos e socioeconômicos aumenta o sucesso da prática. As conclusões do estudo contribuem com lições práticas para aumentar a participação no monitoramento. Destacamos, dentre elas, a importância de estratégias para aumentar a cooperação entre os comunitários, a disseminação de informações sobre os possíveis impactos negativos da coleta e do comércio de recursos naturais, e o fornecimento de compensações financeiras equivalentes ao custo de oportunidade de participação

Moderators of Positive and Negative Spillover

Smith, Sara Rose 01 January 2019 (has links)
Two studies explored individual difference moderators of spillover. Positive spillover occurs when one prosocial behavior leads to an increase in subsequent prosocial behavior, whereas negative spillover or moral licensing occurs when one prosocial behavior leads to a decrease in prosocial behaviors. The moderators of interest were internal motivation, external motivation, and preference for consistency. It was predicted that those who exhibit high external motivation would demonstrate negative spillover, those who exhibit internal motivation would demonstrate positive spillover, and those with high preference for consistency would demonstrate positive spillover. Although these moderation predictions were not supported, Study 1 replicated previous work demonstrating moral licensing, or negative spillover. Participants who completed an initial non-prejudiced act later donated less money to a charity supporting racial equality than participants in the neutral control condition. The results of Study 2 demonstrated positive spillover. Participants who completed an initial pro-environmental act were more likely to help a local environmental organization compared to those who completed a neutral initial task. Future research is needed to understand the cause of the differing results, including measuring potential mediators in future studies.

The Study of Community Residents¡¦ Participation Behavior Model in Environmental Improvement Actions

Kuo, Chang-Jen 16 July 2008 (has links)
During the past decade, the environmental issue has been an important concern of public affairs because the problems generating from the physical environment are the main focus of local development. Generally, the most effective work of community development is to encourage people to participate in environmental improvement actions. For example, the literature has indicated that individual is the most important factor for environmental improvement actions. Thus, people who highly participate in the community affairs often have better performances on community improvement actions. Base on an efficient society and the budget of government downsizing, promoting community residents to actively participate in environmental improvement actions would help the community environment management to be more sustainable and indirectly leading the local development. Concerning community environment, the responsibility for the community, knowledge of environmental action, and the ability of self-control might be correlated with the community residents¡¦ participation behavior in environmental improvement actions. The purpose of study is to explore the relationships among sense of community, the knowledge of environmental action, environmental moral obligation, and participating environmental improvement actions. Four objectives are mainly specified: first, to develop a sense of community scale of Taiwanese population; second, to integrate theories to test a community participation behavior model in environmental improvement actions; third, to understand the influential factors of community residents participation in environmental improvement actions; finally, to compare and interpret community residents participation in environmental improvement behavior model and ¡§Theory of Planned Behavior¡¨. This study surveyed community residents who ever participated in ¡§urban community landscape renaissance project¡¨ supported by Construction and Planning Agency, and ¡§rural community landscape renaissance project¡¨ founded by Soil and Water Conservation Bureau. A total of 616 community residents were administrated a self-report questionnaire. Further analysis of the data based on comparing respondent¡¦s residence, respondents were grouped into to urban planning district group and non-urban planning district group. Structural Equation Modeling (SEM) method was then employed to test a conceptual model. There were nine domains proposed in the conceptual model. Five of nine domains adopted from planning behavioral theory included ¡§attitude¡¨, ¡§subjective norm¡¨, ¡§perceived behavioral control¡¨, ¡§behavioral intention¡¨ and ¡§behavior¡¨. One of nine domains, ¡§self-efficacy¡¨, was chosen from social cognition theory. Two of nine domains from environmental citizen behavioral model were ¡§knowledge of environmental action¡¨, ¡§environmental moral obligation¡¨. ¡§Sense of community¡¨ was referenced to the last domain. The findings provided support for eight hypotheses and two hypotheses were partial supported. The detailed descriptions of hypothesis-testing results were as below. Eight hypotheses supported, they included: (1) After residents reflected on the ¡§subjective norm¡¨, the ¡§attitude¡¨ toward participating environmental reform behaviors was remarkably promoted. (2) Resident¡¦s ¡§attitude¡¨ significantly influenced their ¡§behavioral intention¡¨ of participating environmental improvement behaviors. (3) Resident¡¦s ¡§perceived behavioral control¡¨ significantly impacted their ¡§behavioral intention¡¨ of participate in environmental improvement behaviors. (4) Resident¡¦s ¡§sense of community¡¨ significantly impacted their ¡§behavioral intention¡¨ of participating environmental improvement behaviors. (5) Resident¡¦s ¡§knowledge of environmental action¡¨ significantly impacted their ¡§self-efficacy¡¨. (6) Resident¡¦s ¡§self-efficacy¡¨ significantly effected their ¡§perceived behavioral control¡¨. (7) Resident¡¦s ¡§environmental moral obligation¡¨ significantly impacted their ¡§attitude¡¨ of participating environmental improvement behaviors. (8) Resident¡¦s ¡§behavioral intention¡¨ significantly impacted their participating environmental improvement ¡§behaviors¡¨. Two hypotheses were partial supported: (1) Only in non-urban planning district resident¡¦s ¡§subjective norm¡¨ significantly impacted their ¡§behavioral intention¡¨ of participating environmental improvement behaviors. (2) Only in urban planning district and all districts resident¡¦s ¡§perceived behavioral control¡¨ significantly impacted their ¡§attitude¡¨ of participating environmental improvement behaviors. Additionally, the findings confirmed that Italian Sense of Community Scale (ISCS) was an appropriate scale to measure Taiwanese population¡¦s sense of community. These findings provide researchers and practitioners for insight of resident¡¦s participation in environmental improvement, which is better than ¡§Theory of Planned Behavior¡¨.

Výzkum šetření energiemi v domácnosti ve světle teorie plánovaného chování a modelu aktivovaných norem / An Examination of Household Energy Conservation Behavior in the Framework of Theory of Planned Behavior and Norm Activation Model: Prague Case

Boyaci, Çagatay January 2021 (has links)
This M.A. thesis aims at investigating the socio-psychological motivations and demographic factors related to how individuals perform energy conservation behavior in the household domain. For this reason, two approaches to this sociological issue, the Theory of Planned Behavior and Norm Activation Model, were comprehensively examined to be adequately combined into one experimental model that would determine and help to explain the motivations on the energy conservation behaviors in households. In total, 303 respondents were surveyed who have a residency in Prague by sharing an online-based questionnaire in various Facebook groups between April 28, 2021, and July 3, 2021. In order to test the created hypotheses according to the developed model of the research study, structural equation modeling and ANOVA analysis were employed. As a result, the findings show that combining the Theory of Planned Behavior and the Norm Activation Model gives promising results in explaining the socio-psychological motivations of household energy conservation behaviors. The author of the thesis concludes that social norms have a positive influence on personal norms, and further the personal norms have a positive impact on intentions, and therefore the intentions directly impact the household energy conservation behavior....

Can sustainable investments act as a bridge between the economy and the environment? : A qualitative study about sustainable investments / Kan hållbara investeringar fungera som en bro mellan ekonomin och klimatet? : En kvalitativ studie om hållbara investeringar

Björkman Sjölund, Fanny, Fossheim, Tina January 2021 (has links)
The following study presents the results from one focus group discussion and eight individual interviews investigating how sustainable investments impact climate change. The demand for sustainable investments is currently growing, but there is a lack of research conducted within the area. We therefore aim to fill an academic knowledge gap surrounding the understanding of sustainable investments. To achieve this, we to identified the concepts defining sustainable investment practices and simultaneously identified the predominant factors for investors when making them. To assess the practice characteristics, we compared it with traditional investments. The informants were investors and professionals with occupations connected to sustainable investments. Furthermore, the study has the theoretical frameworks of the ecological modernization theory and value-belief-norm theory for assessing and analyzing study results. The results and conclusion of the study were that there is no universal definition of sustainable investments, causing distrust and concerns regarding the practice. Therefore, definitive conclusion about what sustainable investments can achieve for the climate is challenging to assess. Informants' willingness to invest in sustainable investments was connected to their values and knowledge. Results show a knowledge gap between individual's understanding of investments climate impact due to lack of accessible information for some investors. Finally, regulations concerning sustainable investments came into force during the time of the study. / I uppsatsen presenterar vi resultaten från en fokusgrupp och åtta intervjuer där vi studerat hur hållbara investeringar påverkar klimatförändringarna. Efterfrågan på hållbara investeringar växer men för närvarande saknas det forskning inom området. Vi strävar därför efter att fylla ett akademiskt kunskapshål kring förståelsen om hållbara investeringar. För att uppnå det ville vi identifiera begreppen som definierar “hållbara investeringar” och hitta de avgörande faktorerna för investerare när de väljer att investera hållbart. För att bedöma hållbara investeringar jämförde vi dess egenskaper med traditionella investeringar. Informanterna var investerare och yrkesverksamma med yrken kopplade till hållbara investeringar, vidare bygger studien på teorierna om ekologisk modernisering och value-belief-norm theory. Resultaten och slutsatsen från studien visar att det inte finns någon universell definition av en hållbar investering, något som orsakar misstro och oro angående praxis. Det är därför svårt att dra en absolut slutsats om vad hållbara investeringar kan uppnå för klimatet. Informanternas vilja att investera i hållbara investeringar baserades på deras värderingar och kunskap. Det fanns även kunskapsluckor mellan individerna angående investeringarnas påverkan på klimatet på grund av brist på tillgänglig information för vissa investerare. Slutligen trädde regler om hållbara investeringar i kraft under studietiden.

Examining Employee Motivation, Environmental Systems, and Corporate Social Responsibility in Proenvironmental Behavior

Warrick, Brian 01 January 2016 (has links)
The World Health Organization has pointed to climate change as the most significant issue in the 21st century as a result of greenhouse gas emissions and environmental pollution. Organizations are leaning toward corporate social responsibility (CSR) and environmental management systems (EMS) to reverse the current trend; however, these efforts are often ineffective or pooly implemented. The purpose of this quantitative study was to determine the extent to which employees' proenvironmental behavior relates to their protection motivation and organizational identification, as well as their perception and knowledge of the organization's CSR and EMS, respectively. Using social identity as the theoretical framework, this research addressed how organizational and intrapersonal factors influence employees' proenvironmental behavior. One hundred-twenty employees from American-based organizations completed an online survey measuring self-assessed proenvironmental behaviors, among other variables. The results from a Pearson correlation analysis indicated that all of the independent variables had a significant positive relationship with employee proenvironmental behaviors. Multiple regression analysis showed that while each variable was a significant predictor of proenvironmental behaviors, only the economic dimension of CSR (β = .300, p = .014) and the self-efficacy dimension of protection motivation (β = .269, p = .037) significantly contributed to the model. Leaders' use of the findings may lead to positive social change through improved environmental performance in the form of decreased pollution, a more efficient use of natural resources, and reduced greenhouse gas emissions, all toward a more sustainable future.
