    French adolescents' environmental friendly behaviour

    International audienceEnvironmental friendly behavior and attitudes have been studied in social sciences since the 1970 with the awakening of an « ecological consciousness ». Psychology has been actively taking part in these studies since then (Maloney & Ward, 1973, Oskamp, 2000, Schmuck & Schultz, 2002). Bronfenbrenner (1979) in his nested system approach, sees the person as seen as a developing entity, in constant interaction with different developing environments. We therefore propose to study two different settings (city / family) around the adolescents which could have an influence on his/her pro-environmental behaviors, as well as the influence of a psychological variable : emotional affinity to nature. In detail we wanted to check the following aspects : Influence of the city : Is the image the adolescent is having of his city (polluted or preserved) influencing his behavior concerning environment ? We took two cities in the south of France, a priori contrasted concerning the image of their environment : the city A. is associated to the positive, nature protecting image of the Camargue, wheres the city B. is defending itself against a negative image du to the industrialisation and pollution of the Berre – Pond nearby. Without having a oriented hypothesis, we could imagine that the positive or negative image of the city induces a propensity in the adolescents to act : either a favorable image encourages pro-environmental behavior (as a social norm), or a negative image calls upon such behavior (as a protective reaction). A second setting we were interested in was the family. Is the fact to live in a family which is engaged in environmental matters induces the adolescent to do the same ? Or would he / she be rather taking his / her distances with this model of behavior ? Different aspects were studied :-parents' role model (what they do) and parents – children's discussions about the environment (what they say). We checked also parents' SES. The third variable studied was psychological. It is the personal experience of and with nature of the adolescent. Kals, Schumacher and Montada (1999) called this « emotional affinity towards nature ». In their study, they showed that emotional aspects also influence the ways adults behaved toward nature. Indeed, cognitive aspects are not the only ones to decide people to act for the environment. Yet, the emotional aspect has been treated rather rarely in the studies of pro-environmental behaviors. The dependent variable was the self-reported frequency of environmental friendly behavior of the adolescent (save water, save electricity, recycle waste…)

    Using evaluation techniques and performance claims to demonstrate public relations impact: An Australian perspective

    Public relations professionals use many methods to demonstrate their contribution to organizational goals, yet it is unclear how their attitudes towards evaluation and the reporting of success matches real outcomes. Ten years after the International Public Relations Association produced an evaluation gold paper, this study combines research on Australian practitioners’ evaluation practices and attitudes, and data from industry awards to identify how practitioners demonstrate their accountability. Data suggest that despite the attention paid to evaluation by the academy and industry, practitioners still focus on measuring outputs, not outcomes to demonstrate performance and continue to rely heavily on media-based evaluation methods

    Remember Gerhard Richter in the Thunderstorm of Beethoven: The Influence of Cross-Sensory Coupling on Memory, Intercultural Communication, and the Verbalization of Paintings and Sounds

    This interdisciplinary study focuses on the perception and verbalization of messages conveyed through instrumental music, soundscapes, and contemporary paintings. International young-adult university students learning German participated in a series of experiments conducted at Friedrich Schiller University in Jena, Germany. To incorporate globalization and cultural difference into this analysis, the author compared the reactions of Western and Asian participants to auditory and visual stimuli. This paper explores the concepts of mixed media, cross-sensory coupling, and esthetic synesthesia, and throws new light on the contribution of cross-sensory coupling to verbalization and to long-term memory processes, from encoding to retrieval. In addition, the author demonstrates how intercultural communication is based upon universal emotions aroused by contemporary paintings, instrumental music and soundscapes

    Advertising value equivalence: PR’s orphan metric

    Get PDF
    The academic approach to measurement and evaluation has long favoured social science methodologies (Broom and Dozier, 1990, Michaelson and Stacks, 2011 and Stacks, 2002), but there has been persistent, widespread practice use of advertising value equivalence (AVE) to express the economic and financial value of public relations activity. This paper investigates the evolution of AVE and discusses whether it arose from clippings agencies, press agentry or other influences on public relations, such as advertising and product promotion

    Defining the gap between research and practice in public relations programme evaluation - towards a new research agenda

    Get PDF
    The current situation in public relations programme evaluation is neatly summarized by McCoy who commented that 'probably the most common buzzwords in public relations in the last ten years have been evaluation and accountability' (McCoy 2005, 3). This paper examines the academic and practitioner-based literature and research on programme evaluation and it detects different priorities and approaches that may partly explain why the debate on acceptable and agreed evaluation methods continues. It analyses those differences and proposes a research agenda to bridge the gap and move the debate forward

    Somatic gene therapy for cancer. The utility of transferrinfection in generating ‘tumor vaccines’

    Get PDF
    The last few years have seen the development of a branch of somatic gene therapy which aims at strengthening the immune surveillance of the body, leading to eradication of disseminated cancer tumor cells and occult micrometastases after surgical removal of the primary tumor. Such a tumor vaccination protocol calls for cultivation of the primary tumor tissue and the insertion of one of three types of genes into the isolated cultured tumor cells followed by irradiation of the transfected or transduced cells to render them incapable of further proliferation. The cells so treated constitute the ‘tumor vaccine’. A review of the literature suggests that for mouse models, in the initial period after inoculation, rejection of the tumor cells is usually effected by non-T-cell immunity, whereas the long-term systemic immune response is based on cytotoxic T-cells. High expression of the gene inserted into the tumor cells may be critical for the success of the vaccination procedure. Examples are given which indicate that transferrinfection, a procedure to introduce genes by adenovirus-augmented receptor-mediated endocytosis, meets some important prerequisites for successful application of this type of gene therapy

    VIRAL ONCOLYSIS: INCREASED IMMUNOGENICITY OF HOST CELL ANTIGEN ASSOCIATED WITH INFLUENZA VIRUS

    A2G mice could be solidly immunized against the Ehrlich ascites tumor by single intraperitoneal injections of homogenized and lyophilized tumor cells which had been infected with oncolytic strains of influenza A virus. Similar homogenates from noninfected tumor cells were not immunogenic, even when mixed with egg-grown virus. The immunizing principle in viral oncolysates could not be separated from the oncolytic virus by differential centrifugation or adsorption to and elution from red cells. It could be inhibited by antibody raised in rabbits against the egg-grown oncolytic virus. This reaction showed serologic specificity. Thus, the immunogenicity of an oncolysate produced with the WSA strain of neurotropic influenza virus could be inhibited by rabbit anti-WSA, but not by rabbit antibody to the TUR strain of fowl plague virus. Conversely, the immunogenicity of an oncolysate prepared with the TUR strain could be inhibited by rabbit anti-TUR, but not by anti-WSA. When mice were preimmunized (primed) with egg-grown WSA virus, their antitumor response to a later injection of WSA oncolysate was of the anamnestic type. Priming with egg-grown influenza B virus had no such effect. It was concluded that the immunogenicity of certain host cell components was greatly increased by incorporation into the makeup of the oncolytic virus
