The relevance and integration of scientific knowledge to conservation management of the locally popular and highly endemic butterfly genus Chrysoritis are investigated within the research fields of taxonomy and biogeography. The butterfly genus Chrysoritis contains at least 41 species endemic to South Africa. The taxonomy of Chrysoritis has reached a state where revisions could easily result in a plethora of names between “lumping and splitting”. In practice, the state of the taxonomy of these butterflies on species level may alter their conservation priority. The two most species rich species groups in Chrysoritis have different centres of endemism, however, a butterfly atlas becomes a necessity to reveal more about their biogeography. There is an absence of butterfly species lists in many of our National Parks and Nature Reserves. Legislation should facilitate rather than limit the valuable role of the amateur lepidopterist to add distribution records. In turn, the amateur lepidopterists should adapt and make an effort to explore unknown localities, apart from monitoring butterflies at their well-known localities. The red listing of localised butterflies in South Africa, including a number of Chrysoritis species, is in need of an urgent review in the light of the most recent IUCN categories. A species such as Chrysoritis dicksoni should be protected by law - but at its known localities. The scenario that real conservation action is only needed if the last known locality of a butterfly is threatened, should be abolished. A paradigm shift to conserve the metapopulations of the highly endemic Chrysoritis genus and not merely a few of its species as items that appear on lists, seems necessary.

Before considering the role of the provinces in nature conservation in the Republic of South Africa (RSA) it is necessary to briefly review the responsibilities of other government agencies in this field:(i) the Department of Planning and the Environment has a co-ordinating function with regard to environmental conservation and land-use planning;(ii) the National Parks Board of Trustees is responsible for the estab-lishment and management of national parks;(iii) the Department of Forestry controls vast natural areas in mountain catchments and also has a system of nature reserves and wilderness areas;(iv) the Sea Fisheries Division of the Department of Commerce and Industries is responsible for the conservation of marine resources including mammals and birds. The two maritime provinces, how-ever, have jurisdiction over estuaries, while Natal also controls inshore fisheries;(v) the Weather Bureau of the Department of Transport is responsible for conservation of oceanic islands used as weather stations;(vi) soil conservation is the responsibility of the Department of Agricul-tural Technical Services.

PurposeBy taking a micro-level perspective, this paper aims to examine the influence of the ongoing paradigm shift from technological to social innovation on principal investigators (PIs) and thereby links the two emerging research fields of entrepreneurial ecosystems and social innovation. The purpose of this paper is to build the basis for future empirical analyses.Design/methodology/approachThe paper is a conceptual paper and therefore focuses on theoretical considerations. Taking a quadruple helix approach, PIs are outlined as central actors of entrepreneurial ecosystems and transformative agents of the innovation process.FindingsPIs can proactively shape the innovation process and thus the shift from technological to social innovation, through various channels. They can affect all other actors of the quadruple helix, e.g. by exerting influence on the process of scientific change, on the public opinion and/or on the industry partners. Further, the paradigm shift might change the universities' role in the quadruple helix, substantiating their importance in the process of social change.Practical implicationsAs PIs are influencing all other actors of the quadruple helix, they are central actors of entrepreneurial ecosystems and thus crucial players in the innovation process. Hence, they need to be supported in fulfilling their role of transformative agents, accelerating and shaping the paradigm shift from technological to social innovation. Universities should therefore reconsider their missions and vision as well as their role within the society.Originality/valueThis paper considers the influence of an ongoing paradigm shift from technological to social innovation on entrepreneurial ecosystems. This work focuses especially on the PIs' role as transformative agents. Therefore, it builds a bridge from entrepreneurial ecosystems to social innovation and thus contributes to both research fields. Moreover, the paper shows the great potential of PIs to influence and shape social innovation.

It is a great pleasure to join in this symposium held on the occasion of the 50th Anniversary of the National Parks Board of South Africa. I am deeply honoured to have been entrusted with presenting the Keynote Address to the symposium, which brings together those responsible for conservation in southern Africa, and I come here representing both the World Wildlife Fund and its sister organisation IUCN, the Interna- tional Union for Conservation of Nature and Natural Resources. Having considered contents of the programme before us, I have felt it appropriate to talk on the subject of "Conserving One Earth". First I wish to look at our Earth as we find it today and then discuss the role of conservation both as a tool for wise development and in ensuring that wild things and wild places can continue to contribute to our quality of life.

AbstractImmunosuppression permits graft survival after transplantation and consequently a longer and better life. On the other hand, it increases the risk of infection, for instance with cytomegalovirus (CMV). However, the various available immunosuppressive therapies differ in this regard. One of the first clinical trials using de novo everolimus after kidney transplantation [1] already revealed a considerably lower incidence of CMV infection in the everolimus arms than in the mycophenolate mofetil (MMF) arm. This result was repeatedly confirmed in later studies [2–4]. Everolimus is now considered a substance with antiviral properties. This article is based on the expert meeting “Posttransplant CMV infection and the role of immunosuppression”. The expert panel called for a paradigm shift: In a CMV prevention strategy the targeted selection of the immunosuppressive therapy is also a key element. For patients with elevated risk of CMV, mTOR inhibitor-based immunosuppression is advantageous as it is associated with a significantly lower incidence of CMV events.

SUMMARY The recent extensive literature on exploration and the resulting scientific advances has failed to highlight the contribution of Austrian enterprise to the study of natural history. The leading role of Joseph II among the neutral powers which assumed the carrying trade of the belligerents during the American War of Independence, furthered the development of collections for the Schönbrunn Park and Gardens which had been set up on scientific principles by his parents. On the conclusion of peace, Joseph entrusted to Professor Maerter a world-encompassing mission in the course of which the Chief Gardener Franz Boos and his assistant Georg Scholl travelled to South Africa to collect plants and animals. Boos pursued the mission to Isle de France and Bourbon (Mauritius and Reunion), conveyed by the then unknown Nicolas Baudin. He worked at the Jardin du Roi, Pamplemousses, with Nicolas Cere, or at Palma with Joseph Francois Charpentier de Cossigny. The linkage of Austrian and French horticultural expertise created a situation fraught with opportunities which were to lead Baudin to the forefront of exploration and scientific research as the century closed in the upheaval of the Revolutionary Wars.

E-governance is a paradigm shift over the traditional approaches in Public Administration which means rendering of government services and information to the public by using electronic means. In the past decades, service quality and responsiveness of the government towards the citizens were least important but with the approach of E-Government the government activities are now well dealt. This paper withdraws experiences from various studies from different countries and projects facing similar challenges which need to be consigned for the successful implementation of e-governance projects. Developing countries like India face poverty and illiteracy as a major obstacle in any form of development which makes it difficult for its government to provide e-services to its people conveniently and fast. It also suggests few suggestions to cope up with the challenges faced while implementing e-projects in India.

Information and communications technologies (ICTs) and the Internet have to a large extent influenced the way information is made available, published and accessed. More information is being produced too frequently and information users now require certain skills to sift through this multitude in order to identify what is appropriate for their purposes. Computer and information skills have become a necessity for all academic programmes. As libraries subscribe to databases and other peer-reviewed content (print and electronic), it is important that users are also made aware of such sources and their importance. The purpose of this study was to examine the teaching of information literacy (IL) in universities in Zimbabwe and South Africa, and the role played by librarians in creating information literate graduates. This was done by examining whether such IL programmes were prioritised, their content and how frequently they were reviewed. An electronic questionnaire was distributed to 12 university libraries in Zimbabwe and 21 in South Africa. A total of 25 questionnaires were returned. The findings revealed that IL was being taught in universities library and non-library staff, was compulsory and contributed to the term mark in some institutions. The study also revealed that 44 per cent of the total respondents indicated that the libraries were collaborating with departments and faculty in implementing IL programmes in universities. The study recommends that IL should be an integral part of the university programmes in order to promote the use of databases and to guide students on ethical issues of information use.
