    Methods of Paradox

    Despite growing scholarly interest in paradoxes, few studies have expressly engaged with the methodological mechanics of ‘doing’ paradox research. First, there are no clearly established guidelines regarding what should count as paradox in research endeavors. Second, there is uncertainty around who sees/thinks/experiences the paradox and what is relevant when it comes to the emergence, choice, interpretation and appropriation of paradoxes in empirical settings. Third, there is still confusion around where one can find evidence of paradoxes. This book chapter aims to shed some light on these methodological shortcomings. We suggest that paradox researchers can deal with these methodological challenges by 1) showing evidence of contradictory, interrelated, simultaneous and persistent paradoxical tensions in the empirical setting, 2) developing reliable and flexible protocols for paradox identification, 3) pushing for multi-level paradox studies, 4) practicing reflexivity, 5) staying close to the context, and 6) leveraging multi-modality

    Particulate matter and airborne fungi concentrations in schools in Athens

    Indoor Air Quality degradation is of exceptional concern due to the potential adverse effects indoor air pollutants have on human’s health. Students are a susceptible group of people, who spend a lot of their time within classrooms. The purpose of this study is to investigate the concentration levels of particulate matter (PM) and total airborne fungi, in school classrooms. Further objective is to examine possible correlations between PM10, PM2.5, PM1, ultrafine particles (UFPs, diameter<100 nm), and airborne fungi. The measurements were performed using fully automated instrumentation. The results indicate that a lot of PM10 concentrations exceeded the proposed daily limit of 50μg/m3. Also, in some cases the concentration of the total airborne fungi indoors, exceeded their concentration outdoors. There is evidence that certain correlations exist between PM and airborne fungi

    Indoor and outdoor distribution of airborne pollutants in naturally ventilated classrooms

    The present study aims at investigating concentration levels of particulate matter PM10, PM2.5, PM1 and UFP as well as of total airborne fungi and their vertical distribution in the indoor and outdoor environment of school classrooms. Measurements were performed in two naturally ventilated high schools in Athens, from January until May 2011. Indoor concentrations of the pollutants will be presented per floor level and indoor to outdoor (I/O) concentration ratios will be estimated as a function of the floor height. The ultimate goal is to create variations’ profile of I/O pollutant ratios, so as to understand the contribution of indoor sources and the extent to which the indoor air quality is being affected by the outdoor pollutants

    Information sharing in an export supply chain relationship : the case of the Jordanian fresh fruit and vegetable export industry

    The aim of this research is to develop, examine and validate a conceptual framework, which explains factors of the export supply chain relationship focusing on information sharing in export supply chain management field. This research seeks to understand the dyadic exporter-producer relationship in the export industry of fresh fruit and vegetables from Jordan to the European Union. Jordan supplies very limited fresh fruit and vegetable exports to the European market and the exporter-producer relationships are still weak, which impedes the emergence of a high performance supply chain within this promising market. There has been a lack of conceptual and empirical research on information sharing, which limits the understanding of the business relationship and there is no theoretical framework analysing export supply chain relationships. Therefore, this research examines the possible association between the following factors: relationship, network and transaction dimensions; information sharing; and export performance. A framework for the influence of information sharing on a dyadic exporter-producer relationship of supply chain management guiding this research is developed initially, based on three perspectives: relationship marketing theory, network theory and transaction cost theory. Qualitative methodology is used to achieve the research aim and objectives in Jordan. The research is comprised of two phases. In phase one, seven interviews with experts are conducted to refine the initial framework for key propositions and propose a framework for supply chain management. In phase two, there are ten multiple-case studies, which contain 40 semi-structured interviews, 40 hours of observations and archival records. These cases are primarily conducted with the selected exporter and producer firms in the export industry of fresh fruit and vegetables. Data are collected and analysed, based on key themes and a case study protocol, which individually explore each exporter-producer relationship ―case‖ in order to examine the proposed framework. Finally, the ten cases are cross-analysed to explain the key findings and to match them to the framework in order to validate it as the final conceptual framework for supply chain management. The research findings support the central premise that specific dimensions of relationships, networks and transactions are the key antecedents of information sharing, which in turn influences export performance. The findings confirm that the exporters and the producers are able to support their relationships through the benefits gained from these dimensions at the relationship, network and transaction levels of the export III Information Sharing in an Export Supply Chain Relationship Luai Jraisat supply chain. It is through this alignment that firms create better information sharing between them. Likewise, the findings suggest that firms will be able to gain strategic advantages from supply chain management based on information sharing and its components, namely content, sharing methods, sources and value, thus suggesting that the firms should apply information sharing to improve financial and non-financial export performance. The research makes key contributions to theory and methodology, and has policy and managerial implications. Theoretical contributions are made to the supply chain management literature by providing a holistic framework for supply chain management to understand the exporter-producer relationship. The research expands on the applications of the three perspectives combined and focuses on information sharing as a key factor. Methodological contributions are offered as this research connects the qualitative methodology to the theory, enabling an analytical generalisation of supply chain management relationships by examining both sides of the dyadic relationship to guide their information sharing. This research expands more on the validity and reliability aspects to ensure the strength of this qualitative empirical research. Policy and managerial implications are addressed for managers and policy-makers. The research limitations and guidelines for future research are discussed.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
