The evolutionary history of Symbiodinium and scleractinian hosts - Symbiosis, diversity, and the effect of climate change

Marine invertebrates representing at least five phyla are symbiotic with dinoflagellates from the genus Symbiodinium. This group of single-celled protists was once considered to be a single pandemic species, Symbiodinium microadriaticum. Molecular investigations over the past 25 years have revealed, however, that Symbiodinium is a diverse group of organisms with at least eight (A-H) divergent clades that in turn contain multiple molecular subclade types. The diversity within this genus may subsequently determine the response of corals to normal and stressful conditions, leading to the proposal that the symbiosis may impart unusually rapid adaptation to environmental change by the metazoan host. These questions have added importance due to the critical challenges that corals and the reefs they build face as a consequence of current rapid climate change. This review outlines our current understanding of the diverse genus Symbiodinium and explores the ability of this genus and its symbioses to adapt to rapid environmental change.

Critical practice and the public pedagogy of environmental and conservation media

Natural History filmmaking has a long history but the generic boundaries between it and environmental and conservation filmmaking are blurred. Nature, environment and animal imagery has been a mainstay of television, campaigning organisations and conservation bodies from Greenpeace to the Sierra Club, with vibrant images being used effectively on posters, leaflets and postcards, and in coffee table books, media releases, short films and viral emails to educate and inform the general public. However, critics suggest that wildlife film and photography frequently convey a false image of the state of the world’s flora and fauna. The environmental educator David Orr once remarked that all education is environmental education, and it is possible to see all image-based communication in the same way. The Media, Animal Conservation and Environmental Education has contributions from filmmakers, photographers, researchers and academics from across the globe. It explores the various ways in which film, television and video are, and can be, used by conservationists and educators to encourage both a greater awareness of environmental and conservation issues, and practical action designed to help endangered species. This book is based on a special issue of the journal Environmental Education Research.

Informational institutions in the agrifood sector:meta-information and meta-governance of environmental sustainability

In the agrifood sector, the explosive increase in information about environmental sustainability, often in uncoordinated information systems, has created a new form of ignorance ('meta-ignorance') that diminishes the effectiveness of information on decision-makers. Flows of information are governed by informal and formal social arrangements that we can collectively call Informational Institutions. In this paper, we have reviewed the recent literature on such institutions. From the perspectives of information theory and new institutional economics, current informational institutions are increasing the information entropy of communications concerning environmental sustainability and stakeholders' transaction costs of using relevant information. In our view this reduces the effectiveness of informational governance. Future research on informational governance should explicitly address these aspects.

The Mismanagement of Environmental Conflicts

During the Communist regime, companies' conflicts with the public were hidden. The public did not have the right to express their objection. Recent Hungarian law, however, supports people's right to influence decisions that have an impact on their lives, but attitudes change slowly. In this article, I show the typical methods of companies' mismanagement of environmental conflicts. The first part of the article concentrates on strategic issues, and the second one emphasizes mistakes in communication with local communities. There are signs that Hungarian companies have already started to learn their lesson, but they also need help to face the new situation of the post-Communist era. Conflict theory and conflict resolution techniques may help them to deal with communication problems and to reach win-win solutions. Although not unknown, facilitation is not a common technique in Hungary yet. This means that there is potential for its development.

Környezeti kockázatok felmérése. Paraméterek bizonytalanságának hatása a kockázatkezelési döntéshozatalra = Assessment of environmental risks – effects of parameter uncertainty to the risk management decisions

A környezeti kockázatok megfelelő felmérése és kezelése napjaink egyik legfontosabb kérdése, nemcsak a szakmai, hanem a széles értelemben vett közvélemény számára. A szerző cikkében azt vizsgálja, hogy a környezeti kockázatok felmérésének milyen megközelítései vannak. Kulcskérdésként pedig arra koncentrál, hogy a kockázatkezelési döntéseket hogyan befolyásolja a becslések bizonytalansága. Először a környezeti kockázat definícióját adja meg, majd azt mutatja be, hogy a környezeti kockázatok kezelésére vonatkozó megközelítések milyen párhuzamban állnak a pénzügyi rendszerrel, mint komplex rendszerre vonatkozó megközelítésekkel. Végül a jelenleg legnagyobb kockázatoknak tartott környezeti kockázatokat ismerteti röviden. A cikk második részében kockázatkezelési alternatívákat mutat be, és azt, hogy a kockázatkezelési lépések kiválasztását befolyásolja a bizonytalanság. Ezt illusztrálandó Brouwer-Blois (2008) modelljét használva a soklépéses szimulációt és alternatív döntési kritériumot – a kritikus (extrém) költség-hatás mutatót – alkalmazza. _____________ Adequate assessment and management of environmental risks is a key question nowadays also for professional experts and also for the overall public. In this article the author examines the different approaches concerning environmental risks. He concentrates as a key question the influence on risk management decisions of uncertainties raised by our estimations. First he analyses the definition of environmental risks, and he shows the similarities and differences between approaches concerning environmental risks and risks threatening financial system, and finally he gives short overview on the most current environmental risks. In the second part of the paper he presents risk management alternatives and analyses the influential power of uncertainty on risk management decisions. In order to illustrate this phenomenon the author applies the model of Brouwer-Blois (2008) with multistep simulation and an alternative decisive criterion, the ranking based on critical (extreme) cost to effect measure.

Az 1990-2000 között benyújtott magyar szabadalmi bejelentések környezeti hatásának idősoros elemzése (Time series analysis of environmental effects of submitted Hungarian patents between 1990 and 2000)

A szerző e kutatás keretében az 1990–2000 közötti időszak magyar intézményi és egyéni szabadalmi bejelentők, illetve jogosultak („szabadalmasok”) szabadalmainak környezeti hatását vizsgálja. Konkrétan az ebben az időszakban a Magyar Szabadalmi Hivatalnál benyújtott szabadalmi bejelentésekből elfogadott szabadalmakat tanulmányozza, a PIPACS adatbázisban található szabadalmi leírások alapján. A pozitív környezeti hatású szabadalmak száma, valamint az összes szabadalomhoz viszonyított aránya alapján von le következtetéseket a magyar környezeti innovációs tevékenységről, és ennek potenciális magyar környezeti hatásáról. A pozitív környezeti hatású szabadalmak összes megadott szabadalomhoz viszonyított aránya az időszakban 92%-os szignifikanciaszinten növekszik. _______

A láthatatlan kéz – szemelvények egy metafora történetéből (The invisible hand - extracts from the history of a metaphor)

A láthatatlan kéz Adam Smith nyomán a közgazdaságtan legismertebb metaforája lett, de jelentősége és értelmezése máig megosztja a közgazdászokat és eszmetörténészeket. Az interpretációk skálája rendkívül széles: mértékadó közgazdászok szerint ez a közgazdaságtan alapeszméje, míg mások Smith ironikus tréfájának vélik. A tanulmány áttekinti a láthatatlan kéz Smith előtti használatát teológiai, politikai és irodalmi szövegekben és a hozzájuk kapcsolódó interpretációkat. Ezt követően bemutatja, hogyan alkalmazta Smith a nevezetes kifejezést a merkantilista politika ironikus és paradox kritikájaként, és miként került a 19. század végétől e metafora a Smith-olvasatokban központi helyre, majd miként vált kérdésessé ez a felfogás a 2008-as válság nyomán. ____ Adam Smith's phrase the invisible hand has become the best-known metaphor in economics, yet both its interpretation and its relevance are hotly debated by economists and intellectual historians. The range of opinions is wide: several leading economists view it as the founding idea in economics and social studies, some historians see it as an ironic jest by Smith. The study surveys the different uses of the metaphor in theological, political and literary texts before Smith and reconstructs the "invisible hand" passage in The Wealth of Nations as an ironic and paradoxical critique of mercantilist policy. A vast literature has emerged since the late 19th century treating the metaphor in various way, ranging from the description and justification of free markets to the claim that it is a purely fictitious mechanism. The critical approach to it has become stronger since the great recession of 2008.

Market valuation of environmental performance

This research investigated the general association between corporate environmental performance and the firms’ annual returns independent of any particular environmental event. The association analysis was based on the most recent environmental data for the years 2006, 2007, and 2008. The results indicated that while some environmental variables were significantly associated with firms’ returns, the majority were not. The results also indicated that environmental concerns were more likely to be associated with increase in the firm value than were environmental strengths; however, there were no mean differences between firms whose environmental performance increased as compared with those whose performance deteriorated. Overall, the results provided support for the perspective that environmental strengths require firm expenditures that place additional financial burdens on firms, resulting in lower stock returns.^
