Motivations and Incentives for Pro-Environmental Behaviour in Peru: A Behavioural and Experimental Economics Analysis
Full text linkIn my PhD, I make use of behavioural and experimental economics to analyse motivations and incentives for pro-environmental behaviour (PEB). By focusing on the case of Peru, I draw on a country with a rising middle class and increasing carbon emissions, generating insights for a highly relevant consumer group. The core of my thesis is based on three self-contained chapters. In Chapter 1, I investigate the role of individual preferences for PEB based on a household survey with 900 middle class households in Lima. I show that particular preferences matter for particular PEBs: social preferences matter mainly for saving-energy behaviour; time, risk and ambiguity preferences matter for the consumption of plastics; and time and ambiguity preferences for expenditures on electricity. In Chapter 2 and 3, I conduct two field experiments with 1,709 and 1,392 households, respectively, in the context of a municipal recycling programme in Lima. In Chapter 2, I shed light on the role of social norms and individual beliefs about social norms for people’s decision to sign up to the recycling programme. I show that randomly correcting negatively biased beliefs about dynamic and injunctive norms in the recycling behaviour of others causally raises people’s willingness to sign up as well. I further underline the effectiveness of dynamic norms to motivate sustainable behaviour even in situations where unsustainable norms prevail. In Chapter 3, I test whether sms reminders can increase the recycling activity of enrolled households in the recycling programme, contrasting the effect of continuous vs. interrupted vs. restarted reminders. I show that sms reminders are generally effective to encourage recycling behaviour, and that sending reminders continuously is most effective over time, which suggests that limited attention on the recycling day itself is a main obstacle. The findings of my PhD are of great relevance for scientific debates in the respective fields, as well as for policy makers that aim to encourage sustainable behaviour
The role of the consumer and systemic policy mixes for circular business models in the EU
No full textRecent decades have shown an unprecedented growth in demand for resources, with a trend that is projected to accelerate in the future. Policymakers around the world have started to recognise that transitioning to a more resource-efficient and circular economy (CE) is key to addressing this challenge. Two important enablers for the transition to a CE are circular business models (CBMs) and consumers. The two are interlinked, as demand shifts among consumers can foster the development and supply of new business models, which in turn require the uptake by consumers to be successful. To promote the development and increase the uptake of new CBMs, policymakers need to provide the respective regulatory frameworks and incentives. Doing so requires systemic policy mixes that go beyond encouraging technological innovations and include targeting the demand side as well. This paper zooms in on the role of the consumer for CBMs, discusses potential consumer barriers to CBM demand, and outlines how policy-making can address these barriers by applying systemic mixes of instruments to tackle the macro-, meso-, and micro-level factors that influence consumer demand simultaneously. While the macro-level describes the economic context of consumers' decision-making, that is, the availability and supply, infrastructure and price of CBMs in the market, the meso-level characterises the social environment, including social norms and social status, whereas the micro-level focuses on individual characteristics such as consumption habits, security and quality concerns, and environmental knowledge or concern. This paper illustrates how the different consumer barriers are closely interlinked, and that, ideally, policymakers should target all three levels jointly to encourage CBM demand most effectively. In doing so, policymakers should consider the principles of the waste hierarchy in order to maximise the environmental benefits of CE policy mixes. The paper mostly takes a European perspective on the topic, especially when discussing relevant policy frameworks, and reflects on potential differences to other regions, particularly in the Global South, when appropriat
New kids on the recycling block: The role of supermarkets and bodegas for sustainable consumer behaviour in Lima
Full text linkOnly 4% of total municipal solid waste in Lima is recycled. Supermarkets and bodegas are in a unique, highly relevant position for the transition towards a circular economy due to their direct influence on customers’ consumption patterns. This paper explores the role of supermarkets and bodegas for consumer recycling behaviour, looking both at already implemented practices and possibilities for the future. Based on semi-structured interviews conducted with key actors in the recycling sector in 2019 and 2020, we analyse the sector regarding its main actors and their different interests, the interactions between them and the regulatory framework, as well as specific initiatives undertaken to increase recycling. We then compare the main mechanisms through which consumer recycling behaviour can be influenced between supermarkets and bodegas based on the three categories convenience, knowledge and socio-psychological factors. Our in-depth analysis outlines the different pros and cons for each of the three categories in detail
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
