Fashion products made from repurposed materials (e.g., backpacks made from pineapple leaves) have become more prevalent nowadays, and their environmental sustainability is one of the core advantages. Yet, it is currently unclear how consumers respond to products made from repurposed materials. We conducted three experiments to examine the effects of three material features, namely function, sustainability, and distinguishability, on consumer preferences for fashion products made from repurposed materials. The results indicate that, when the function of repurposed materials is as good as that of conventional materials, consumers prefer a product made from repurposed materials over the same product made from conventional materials. Also, consumers in general prefer repurposed materials to be less visually distinguishable. Finally, when the sustainability of the repurposed products is emphasized, consumers appear more likely to choose products made from repurposed materials, even when these products have an inferior function. In conclusion, to promote fashion products made from repurposed materials, marketers may emphasize the function and sustainability of repurposed materials, and producers may manufacture repurposed materials that visually resemble conventional materials.

Comprehensive and reliable information on anthropogenic sources of greenhouse gas emissions is required to track progress towards keeping warming well below 2°C as agreed upon in the Paris Agreement. Here we provide a dataset on anthropogenic GHG emissions 1970-2019 with a broad country and sector coverage. We build the dataset from recent releases from the “Emissions Database for Global Atmospheric Research” (EDGAR) for CO2 emissions from fossil fuel combustion and industry (FFI), CH4 emissions, N2O emissions, and fluorinated gases and use a well-established fast-track method to extend this dataset from 2018 to 2019. We complement this with information on net CO2 emissions from land use, land-use change and forestry (LULUCF) from three available bookkeeping models.

1. Natural populations deliver a wide range of products that provide income for millions of people and need to be exploited sustainably. Large heterogeneity in individual performance within these exploited populations has the potential to improve population recovery after exploitation and thus help sustaining yields over time. 2. We explored the potential of using individual heterogeneity to design smarter harvest schemes, by sparing individuals that contribute most to future productivity and population growth, using the understorey palm Chamaedorea elegans as a model system. Leaves of this palm are an important non-timber forest product and long-term inter-individual growth variability can be evaluated from internode lengths. 3. We studied a population of 830 individuals, half of which was subjected to a 67 % defoliation treatment for three years. We measured effects of defoliation on vital rates and leaf size – a trait that determines marketability. We constructed integral projection models in which vital rates depended on stem length, past growth rate, and defoliation, and evaluated transient population dynamics to quantify population development and leaf yield. We then simulated scenarios in which we spared individuals that were either most important for population growth or had leaves smaller than marketable size. 4. Individuals varying in size or past growth rate responded similarly to leaf harvesting in terms of growth and reproduction. By contrast, defoliation-induced reduction in survival chance was smaller in large individuals than in small ones. Simulations showed that harvest-induced population decline was much reduced when individuals from size and past growth classes that contributed most to population growth were spared. Under this scenario cumulative leaf harvest over 20 years was somewhat reduced, but long-term leaf production was sustained. A three-fold increase in leaf yield was generated when individuals with small leaves are spared. 5. Synthesis and applications This study demonstrates the potential to create smarter systems of palm leaf harvest by accounting for individual heterogeneity within exploited populations. Sparing individuals that contribute most to population growth ensured sustained leaf production over time. The concepts and methods presented here are generally applicable to exploited plant and animal species which exhibit considerable individual heterogeneity. Vital rate and internode dataThis data file contains annual vital rate data (stem length growth, fruit production, survival and leaf production) of 830 individuals of the understorey palm Chamaedorea elegans, collected in a 0.7 ha plot in Chiapas, Mexico, during the period November 2012 - November 2015. A 2/3 defoliation treatment was repeatedly applied to half of the individuals. The data file also contains measurements of the lengths of all internodes of all individuals.

The aim of this study was to identify the attitudes of the public in the United States and in 12 European countries towards foreign policy issues and transatlantic issues. The survey concentrated on issues such as: United States and European Union (EU) leadership and relations, favorability towards certain countries, institutions and people, security, cooperation and the perception of threat including issues of concern with Afghanistan, Iran, and Russia, energy dependence, economic downturn, and global warming, Turkey and Turkish accession to the EU, promotion of democracy in other countries, and the importance of economic versus military power. Several questions asked of respondents pertained to voting and politics including whether they discussed political matters with friends and whether they attempted to persuade others close to them to share their views on politics which they held strong opinions about, vote intention, their assessment of the current United States President and upcoming presidential election, political party attachment, and left-right political self-placement.

Objectives: To evaluate (1) the state of the art in sustainability research and (2) the outcomes of professionals’ adherence to guideline recommendations in medical practice. Design: Systematic review. Data sources: Searches were conducted until August 2015 in MEDLINE, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and the Guidelines International Network (GIN) library. A snowball strategy, in which reference sections of other reviews and of included papers were searched, was used to identify additional papers. Eligibility criteria: Studies needed to be focused on sustainability and on professionals’ adherence to clinical practice guidelines in medical care. Studies had to include at least 2 measurements: 1 before (PRE) or immediately after implementation (EARLY POST) and 1 measurement longer than 1 year after active implementation (LATE POST). Results: The search retrieved 4219 items, of which 14 studies met the inclusion criteria, involving 18 sustainability evaluations. The mean timeframe between the end of active implementation and the sustainability evaluation was 2.6 years (minimum 1.5–maximum 7.0). The studies were heterogeneous with respect to their methodology. Sustainability was considered to be successful if performance in terms of professionals’ adherence was fully maintained in the late postimplementation phase. Long-term sustainability of professionals’ adherence was reported in 7 out of 18 evaluations, adherence was not sustained in 6 evaluations, 4 evaluations showed mixed sustainability results and in 1 evaluation it was unclear whether the professional adherence was sustained. Conclusions: (2) Professionals’ adherence to a clinical practice guideline in medical care decreased after more than 1 year after implementation in about half of the cases. (1) Owing to the limited number of studies, the absence of a uniform definition, the high risk of bias, and the mixed results of studies, no firm conclusion about the sustainability of professionals’ adherence to guidelines in medical practice can be drawn. Results Systematic review sustainabilityFor this review, 4219 items were retrieved and screened based on title and abstract, 185 studies were assessed based on full text reading and 14 studies were selected for analyses.

This research focuses on male and female owned micro enterprises preparing and selling food in Rwanda, Senegal and South Africa. This sector provides livelihoods for many women and men in these countries and this project provides the gender and energy nexus analysis. One of the primary goals of this project is to influence energy policy making and implementation in the focus countries.

LocaGIStics is a support tool for the design of regional biomass delivery chains. It enables to further design and evaluate regional biomass delivery chains that are e.g. the result of initial planning by an energy company or a biobased producer. These general plans are translated in several biomass delivery designs using the variation in logistical concepts covering transport, pre-treatment and conversion options. The performance of every chain design can then be analyzed by comparing the different biomass delivery chains on the following environmental and economic indicators. A regional case study was performed in Aragón (Spain) using the LocaGIStics tool. In this case study maps were used where the biomass availability is specified for 2.5 x 2.5 grid cells. Data about the logistical components were supplied partly by the energy supplying company that was involved. This paper shows the main outcomes of this case study.

An important outcome of a university business education is to shape individuals who are capable of working in and operating businesses that deliver economically profitable, socially responsible and ecologically viable services. In preparing future sustainable tourism workers, universities also need to design curricula that develop students’ skills in critical thinking and acting with a sense of ethics and empathy. Research evidence indicates, however, that students often graduate without these skills. A potential reason for this is the design of tourism curricula based on weaker conceptualisations of sustainability (e.g. triple bottom line) as opposed to stronger conceptualisations of sustainability (more holistic and inclusive approaches). Another possible reason could be that educators are not successfully cultivating students’ abilities to think in more complex ways about sustainability nor are they adequately acknowledging the ways in which their students make sense of a complex concept such as sustainability. To add to the complexity of the sustainability phenomenon, there is growing international pressure on the tourism industry by the United Nations (UN) to work towards achieving the 17 global sustainable development goals (SDGs) by 2030. Despite recognition that tourism can help contribute towards the SDGs, a UN report provides evidence that tourism policymakers are not actively and sufficiently engaging with the SDGs. The UN’s recognition of the tourism industry’s ability to advance the SDGS through economic growth (SDG 8) is further problematic, even if this is seen as sustainable economic growth. The term ‘sustainable development’ has long been contested as a weaker form of sustainability due to its progrowth and development emphasis. Given the current global overtourism crisis, it seems more important than ever that universities pay attention to how sustainable tourism is being interpreted and implemented. This is necessary if educators are to truly encourage stronger sustainability mindsets in future tourism workers and change makers. Therefore, the overarching aim of this thesis is to explore how conceptualisations of strong sustainability amongst university students can be strengthened. This study is the first to explore the usefulness of variation theory in strengthening conceptualisations of strong sustainability amongst university tourism students. It provides the tourism literature with evidence of: 1) the conceptualisation of sustainability currently being integrated into undergraduate tourism courses by universities internationally; 2) the benefits of phenomenography as a research approach for studying qualitative difference in understanding concepts such as sustainability and sustainable tourism; 3) the viability of using a learning study approach to develop ‘stronger’ understandings of sustainability; and 4) the potential of variation theory to explain how individuals acquire understandings of sustainability. The empirical research is presented in three studies to address three main research objectives. The first research objective was ‘to identify the conceptualisations of sustainability currently being used in university undergraduate sustainable tourism courses internationally’. The first study, in Chapter III, identifies whether ‘strong sustainability’, sustainability skills and the SDGs are currently underpinning 60 international sustainable tourism courses. Chapter IV ‘explores the different ways in which tourism students, academics and industry practitioners currently conceptualise sustainability’ by conducting phenomenographic interviews with 20 participants. A continuum of less to more complex understandings of sustainability was then developed to identify qualitatively different ways of understanding sustainability. The third research objective was ‘to investigate alternate teaching and learning approaches that might encourage stronger conceptualisations of sustainability amongst undergraduate tourism students’. Chapter V, discusses how the continuum explored in Chapter IV was used in an Australian university sustainable tourism course, underpinned by variation theory, to implement a learning study to enhance students’ understandings of sustainability and the conceptual complexity of the term sustainability. The findings revealed that internationally, sustainable tourism courses do not include ‘very strong’ conceptualisations of sustainability, and that sustainability pedagogies (such as systems and holistic thinking) are not widely used. Phenomenographic interviews with (predominantly Australian-based) lecturers, students and industry workers initially revealed four qualitatively different ways of understanding sustainability ranging from weak to very strong understandings of sustainability. Whilst many tourism lecturers seemed to show understandings of moderate to strong sustainability, very few showed very strong sustainability conceptualisations. This implies that some tourism courses may potentially be designed and underpinned by a weak to moderate articulation of sustainability. These interviews also revealed that industry owners tended to demonstrate a much stronger sustainability understanding than tourism lecturers. Most industry owners had a longer-term focus and key motives centred on giving back to society and a ‘pay-it-forward’ attitude towards the environment. Further findings in the learning study revealed that variation theory offers a valuable teaching and learning strategy to help develop more complex conceptualisations of ‘very strong’ sustainability within a university tourism course. Based on these findings, a number of implications for theory and practice are examined. These include recommendations regarding the design of sustainable tourism courses such as strengthening the sustainability conceptualisations underpinning them; better integration of the SDGs; and the development of critical and systems thinking skills. The three studies also provide examples for use in practice. For example, in Chapter III, a questioning strategy is provided. The phenomenographic continuum in Chapter IV provides a teaching and learning tool for educators to incorporate into sustainability courses to help students’ understandings of the phenomena. Chapter V provides insight into how this continuum can be incorporated into a learning study and provides practical ways of using variation theory. By implementing the continuum into teaching and learning activities, both educators and industry can develop deeper and stronger conceptualisations of sustainability for the tourism industry. Limitations of the study are discussed, and recommendations put forward for future research. In addition, ways in which educational institutions and governments can use the findings of the study to enhance teaching and learning, both in the classroom and industry workplaces, are discussed. Such enhancements will provide a foundation of ‘strong sustainability’ mindsets within our future tourism industry, which in turn will contribute to the 2030 SDGs being achieved.
