Chlorophyll fluorescence is the most widely used set of techniques to probe photosynthesis and plant stress. Its great versatility has given rise to different routine methods to study plants and algae. The three main technical platforms are pulse amplitude modulation (PAM), fast rise of chlorophyll fluorescence, and fast repetition rate. Solar-induced fluorescence (SIF) has also gained interest in the last few years. Works have compared their advantages and their underlying theory, with many arguments advanced as to which method is the most accurate and useful. To date, no data has assessed the exact magnitude of popularity and influence for each methodology. In this work, we have taken the bibliometrics of the past decade for each of the four platforms, have evaluated the public scientific opinion toward each method, and possibly identified a geographical bias. We used various metrics to assess influence and popularity for the four routine platforms compared in this study and found that, overall, PAM currently has the highest values, although the more recent SIF has increased in popularity rapidly during the last decade. This indicates that PAM is currently one of the fundamental tools in chlorophyll fluorescence.

Social Memories

Along with many different definitions of archaeology, from the inception of the discipline to the present, it may be valid to assert that it is a kind of complex dialogue on heritage with the public of contemporary societies. In this dialogue, archaeologists have directly constructed social memories and modern identities, this being an exceptional responsibility, and have at the same time been susceptible to ethnocentric transfers of modern values and expectations into the images of the past. In this respect, it may well be said that the public is not only the most important consumer of cultural heritage, but also an active participant indirectly influencing the shaping of archaeological interpretations of the past. Thanks to the global trends in the discipline, but also due to the administrative decisions of the Ministry of Culture and Information, archaeology in Serbia is compelled to intensify contacts with the public and to make the results of our work more readily accessible and economically sustainable. The paper aims to offer a short overview of theoretical premises of various models of collaboration of archaeology and the public, to point to the advantages and shortcomings, as well as the consequences of these approaches, thus warning of the many potential problems stemming from the uncritical dissemination of information on the past and heritage to the general public.

Abstract Most non-destructive methods for plant stress detection do not measure the primary stress response but reactions of processes downstream of primary events. For instance, the chlorophyll fluorescence ratio Fv/Fm, which indicates the maximum quantum yield of photosystem II, can be employed to monitor stress originating elsewhere in the plant cell. This article describes the properties of a sensor to quantify herbicide and pathogen stress in agricultural plants for field applications by the Fv/Fm parameter. This dedicated sensor is highly mobile and measures images of pulse amplitude modulated (PAM) chlorophyll fluorescence. Special physical properties of the sensor are reported, and the range of its field applications is defined. In addition, detection of herbicide resistant weeds by employing an Fv/Fm-based classifier is described. The PAM-imaging sensor introduced here can provide in-field estimation of herbicide sensitivity in crops and weeds after herbicide treatment before any damage becomes visible. Limitations of the system and the use of a classifier to differentiate between stressed and non-stressed plants based on sensor data are presented. It is concluded that stress detection by the Fv/Fm parameter is suitable as an expert tool for decision making in crop management.

The Public Sphere

This paper examines two young adult novels, Run Like Jäger (2008) and Summer of Fire (2009), by Canadian writer Karen Bass, which centre on the experiences of so-called ordinary German teenagers in World War II. Although guilt and perpetration are themes addressed in these books, their focus is primarily on the ways in which Germans suffered at the hands of the Allied forces. These books thus participate in the increasingly widespread but still controversial subject of the suffering of the perpetrators. Bringing work in childhood studies to bear on contemporary representations of German wartime suffering in the public sphere, I explore how Bass's novels, through the liminal figure of the adolescent, participate in a culture of self-victimisation that downplays guilt rather than more ethically contextualises suffering within guilt. These historical narratives are framed by contemporary narratives which centre on troubled teen protagonists who need the stories of the past for their own individualisation in the present. In their evacuation of crucial historical contexts, both Run Like Jäger and Summer of Fire support optimistic and gendered narratives of individualism that ultimately refuse complicated understandings of adolescent agency in the past or present.

Abstract Are historic sites and house museums destined to go the way of Oldsmobiles and floppy disks?? Visitation has trended downwards for thirty years. Theories abound, but no one really knows why. To launch a discussion of the problem in the pages of The Public Historian, Cary Carson cautions against the pessimistic view that the past is simply passéé. Instead he offers a ““Plan B”” that takes account of the new way that learners today organize information to make history meaningful.

Traditional Approaches

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.

Over the past several years, transplantology has become one of the fastest developing areas of medicine. The reason is, first and foremost, a significant improvement of the results of successful transplants. However, much controversy arouse among the public, on both medical and ethical grounds. The article presents the most important concepts and regulations relating to the collection and transplantation of organs and tissues in the context of the European Convention on Bioethics. It analyses the convention and its additional protocol. The article provides the definition of transplantation and distinguishes its types, taking into account the medical criteria for organ transplants. Moreover, authors explained the issue of organ donation ex vivo and ex mortuo. The European Convention on Human Rights and Biomedicine clearly regulates the legal aspects concerning the transplantation and related basic concepts, and therefore provides a reliable source of information about organ transplantation and tissue. This act is a part of the international legal order, which includes the established codification of bioethical standards.

Mourning And Melancholia

Abstract In these preliminary reflections, I propose a re-reading of left-leaning political projects’ attachment to the liberal idea of the “public.” I will argue that this attachment is a wounded one that forces nostalgia for the past and prevents dealing with present realities. I want us to attend to this notion of the public by attending to some ideas in psychoanalysis, particularly Sigmund Freud’s and specifically those of mourning and melancholia. This reading does not purport expertise in psychoanalysis and does not offer any kind of psychological diagnosis. I intend on reading psychoanalysis as allegory, as offering us imaginative devices for thinking about the present.
