- Targets for human development are increasingly connected with targets for nature, however, existing scenarios do not explicitly address this relationship. Here, we outline a strategy to generate scenarios centred on our relationship with nature to inform decision-making at multiple scales.

- 1. Scientists have repeatedly argued that transformative, multiscale global scenarios are needed as tools in the quest to halt the decline of biodiversity and achieve sustainability goals.2. As a first step towards achieving this, the researchers who participated in the scenarios and models expert group of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) entered into an iterative, participatory process that led to the development of the Nature Futures Framework (NFF).3. The NFF is a heuristic tool that captures diverse, positive relationships of humans with nature in the form of a triangle. It can be used both as a boundary object for continuously opening up more plural perspectives in the creation of desirable nature scenarios and as an actionable framework for developing consistent nature scenarios across multiple scales.4. Here we describe the methods employed to develop the NFF and how it fits into a longer term process to create transformative, multiscale scenarios for nature. We argue that the contribution of the NFF is twofold: (a) its ability to hold a plurality of perspectives on what is desirable, which enables the development of joint goals and visions and recognizes the possible convergence and synergies of measures to achieve these visions and (b), its multiscale functionality for elaborating scenarios and models that can inform decision-making at relevant levels, making it applicable across specific places and perspectives on nature.5. If humanity is to achieve its goal of a more sustainable and prosperous future rooted in a flourishing nature, it is critical to open up a space for more plural perspectives of human-nature relationships. As the global community sets out to develop new goals for biodiversity, the NFF can be used as a navigation tool helping to make diverse, desirable futures possible.

- Chitosan biopolymer with a deacetylation degree of 85%, was assessed for its capability to adsorb As(V) from drinking water by batch experiments. To characterize the chitosan biopolymer, chitosan was analyzed by FTIR and SEM. The results showed that chitosan is an effective and promising sorbent for As(V) from drinking water. From the batch tests, results showed a maximum adsorption of 355 μg/L of As(V) with 1.18 μg g-1 adsorption capacity at pH 6. The kinetic data, obtained at pH 6 could be fitted with pseudo-second order equation (adsorption capacity: 0.923 μg g-1) and the process was suitably described by a Freundlich (R2 = 0.9933) model than by a Langmuir model (R2 = 0.9741). The results above indicated that chitosan is a very favorable sorbent for As(V) removal from aqueous solution.

Levers and leverage points for pathways to sustainability

Tidskriftsartikel (refereegranskat)abstract
- 1. Humanity is on a deeply unsustainable trajectory. We are exceeding planetary boundaries and unlikely to meet many international sustainable development goals and global environmental targets. Until recently, there was no broadly accepted framework of interventions that could ignite the transformations needed to achieve these desired targets and goals.2. As a component of the IPBES Global Assessment, we conducted an iterative expert deliberation process with an extensive review of scenarios and pathways to sustainability, including the broader literature on indirect drivers, social change and sustainability transformation. We asked, what are the most important elements of pathways to sustainability?3. Applying a social-ecological systems lens, we identified eight priority points for intervention (leverage points) and five overarching strategic actions and priority interventions (levers), which appear to be key to societal transformation. The eight leverage points are: (1) Visions of a good life, (2) Total consumption and waste, (3) Latent values of responsibility, (4) Inequalities, (5) Justice and inclusion in conservation, (6) Externalities from trade and other telecouplings, (7) Responsible technology, innovation and investment, and (8) Education and knowledge generation and sharing. The five intertwined levers can be applied across the eight leverage points and more broadly. These include: (A) Incentives and capacity building, (B) Coordination across sectors and jurisdictions, (C) Pre-emptive action, (D) Adaptive decision-making and (E) Environmental law and implementation. The levers and leverage points are all non-substitutable, and each enables others, likely leading to synergistic benefits.4. Transformative change towards sustainable pathways requires more than a simple scaling-up of sustainability initiatives-it entails addressing these levers and leverage points to change the fabric of legal, political, economic and other social systems. These levers and leverage points build upon those approved within the Global Assessment's Summary for Policymakers, with the aim of enabling leaders in government, business, civil society and academia to spark transformative changes towards a more just and sustainable world.

Late pleistocene and holocene history of genus isoetes L. (Lycopodiophyta) in the Western Rhodope Mountains, Bulgaria. New palynological and palaeoecological data
- 2012

- The genus Isoetes is represented in Bulgaria by one species I. lacustris L. (lake quillwort). It inhabits the littoral areas of some lakes in the Pirin Mountain range. Fossil records of Isoetes in Bulgaria are very scarce. A new palynological study was conducted on sediments collected from Kupena Mire in the Western Rhodope Mountains. The results indicated that lake quillwort was abundant 30 000 years ago and its growth was associated with the presence of shallow lake basins. The species disappeared from the composition of the local flora as the sedimentation regime changed from lacustrine to marsh after the warming of the climate at the onset of the Holocene. This study confirmed the existence of refugial areas during the last glaciation in the mountains of Southeastern Europe, where a number of glacial relics had survived.

I’m not Thrilled about my Colonoscopy : Assessing Sentiment and Emotions from Social Media Posts: An Abstract

- From a consumer marketing perspective, undergoing any surgical procedure is, for the average individual, a “credence” good, those which the quality cannot be ascertained through search, and cannot even be realistically judged after their purchase and consumption (Darby and Karni 1973). MedcineNet is a website containing detailed articles on different medical conditions and diseases as well as detailed articles on various medical procedures like knee replacements, C-sections and colonoscopies. A patient comments section is available on many of these articles that contain comments from patients who have undergone a similar procedure to read. For many perspective patients, the patient comments section may be comforting to read as they prepare for their own procedure. In the case of colonoscopies, most patients don’t have the expertise to know whether they even really needed a colonoscopy or not, and once it has been performed, most patients are not really in a position to judge whether it was performed poorly or well. After surgeries, patients frequently turn to social media to assess the experiences expressed by others and to talk about their own. In this study, we collected 93 patient reviews from MedicineNet from patients who underwent a colonoscopy procedure. We first employ IBM Watson to examine how patients who have undergone colonoscopies talk about their emotions and express sentiment through their comments online. We explore their emotions (anger, disgust, fear, happiness and sadness) and their overall sentiment after undergoing a colonoscopy. While a colonoscopy is not a positive experience for most patients, evidenced by mostly negative sentiment and high levels of fear and sadness, some do express a positive sentiment, and the emotion of joy. This was seen in patients who shared commend that they were happy that the procedure was “over”, or they were relieved when their results indicated no evidence of cancer or other serious illnesses. Limitations are acknowledged, managerial implications identified, and avenues for future research are suggested.
