    Effect of yearly conditions and management practices on ochratoxin a production in sultana seedless vineyards
    (Taylor and Francis Ltd., 2012) Meyvaci K.B.; Aksoy U.; Eltem R.; Altindili A.; Akun T.; Takin E.
    Sun drying of seedless grapes (Vitis vinifera cv. Sultanina) is widely practised in the western Aegean Region providing Turkey with a significant share in the world trade of sultanas. Research was initiated in 1998 to determine the incidence of ochratoxin A (OTA), to identify the major factors resulting in contamination and to develop techniques to reduce or prevent contamination. This paper assesses OTA formation in five experimental vineyards located in Manisa province of Turkey between 1998 and 2003. The cultural practices recorded were tillage (type and timing), fertilisation, plant protection, irrigation, trellising, pruning, GA3 application, harvest maturity and date, and drying practices (type of drying yard, dipping into alkaline solution, length of drying period). In the experimental vineyards, no OTA was found at veraison. OTA levels in grapes harvested at fresh maturity ranged between

    Measurements of environmental pollution in industrial area using magnetic susceptibility method
    (Polish Academy of Sciences, 2012) Kucer N.; Sabikoglu I.; Can N.
    Gaziemir district of Izmir, the Aegean Free Zone, is an industry center of approximately 295 companies that operate in lots of fields such as production, maintenance-repair, trade and that provide 1/3 of total employment in 21 free zones in Turkey. In this study, magnetic susceptibility values of soil samples taking from environment of various factories in Aegean Free Zone have been determined. Magnetic susceptibilities of samples in low and high frequency have been measured by Bartington MS2B magnetic susceptibility measurement device. All of the samples have showed ferromagnetic characteristics and also their pseudosingle-domain structures and super paramagnetic granule additives have been determined by evaluating their graphics connected to frequency.

    Composition and degradation effects on the compaction characteristics of municipal solid wastes
    (Taylor and Francis - Balkema, 2013) Pulat H.F.; Yukselen-Aksoy Y.
    Inordertoprotect environment and human health, MSW mustbestored regularlyand confidently. For safe and economic MSW storage, significant processes are initialized (dumping, spread out, burying and compacting). Compaction is the one of the most important stages of the storage process. Well compacted MSW renders less volume than the same weighted uncompacted MSW. Furthermore, well compaction provides safer storage area. In this study, the effect of composition, degradation, and energy on the compaction behavior of artificially prepared and natural fresh and aged MSW samples were determined. The standard and modified proctor tests were performed on the fresh and aged samples. Artificial samples were prepared in different compositions to examine the effect of composition. In addition to the synthetic MSW samples, natural MSW samples were provided from municipal landfill area of Manisa city. © 2013 Taylor & Francis Group.

    Social Media Engagement of Stakeholders: A Decision Tree Approach in Container Shipping
    (Elsevier B.V., 2020) Surucu-Balci E.; Balci G.; Yuen K.F.
    Social media provides a significant avenue for stakeholder engagement which is crucial to ensure loyalty and satisfaction of stakeholders who possess valuable resources that can influence the business outcomes. Container lines – imperative members of global supply chains and facilitators of international trade – utilize social media to engage their stakeholders due to environmental and commercial complexity of their business. However, not all social media posts generate the same amount of stakeholder engagement. This study aims to identify and examine the social media post characteristics that lead to higher stakeholder engagement in the container shipping market. The study applies Chi-Squared Automatic Interaction Detection method to categorize social media posts based on their engagement levels. The analysis is conducted on the tweets of four global container lines which are posted between 1 September 2018 and 31 January 2019. The results demonstrate that social media posts of container lines have varying effects on engagement level. We found that fluency of tweets, tangibility of company resources in the tweet, vividness level, content type, existence of a link, and existence of a call-to-action significantly influence the container lines’ stakeholder engagement rate. This study is the first that finds out social media post classes based on the interaction between their characteristics and engagement rates by employing a decision tree methodology. The results are expected to help container lines in their social media management and stakeholder engagement policies. © 2019 Elsevier B.V.
