Our CE questions relate to the type of nutritional- content attributes of the chewing gum: calcium, vitamins, Euglena; recommendations about the chewing gum from the Internet, from friends, from 'tokuho' labels certified by Japanese authorities; the amount of nutritional content; and the price of the gum, vertically placed in this order into the choice set. Then, to identify the latent market segment, we utilized a latent class model. As a result, there were two latent segments: one cluster indicated a trade-off structure between price and  nonprice attributes, while another cluster indicated a certain heuristic feature focusing solely on the type of nutritional content and information source, which were placed at the first and second position of alternatives from the top of our choice sets. This suggests that when diffusing brand-new food products such as Euglena foods, we should pay more attention to personal communication, rather than announcements via Internet news sites or blogs.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"実践論文","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Case Study Papers","subitem_heading_language":"en"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"獨協大学情報学研究所"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12559097","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2186-7666","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大床, 太郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井元, 智子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohdoko, Taro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Imoto, Tomoko ","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-05-30"}],"displaytype":"detail","filename":"P-095-J99j-5-4.pdf","filesize":[{"value":"661.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"P-095-J99j-5-4.pdf","url":"https://dokkyo.repo.nii.ac.jp/record/480/files/P-095-J99j-5-4.pdf"},"version_id":"4b62651e-9cd0-453d-9363-30c0ac3f94d9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"選択実験","subitem_subject_scheme":"Other"},{"subitem_subject":"潜在クラスモデル","subitem_subject_scheme":"Other"},{"subitem_subject":"ユーグレナ","subitem_subject_scheme":"Other"},{"subitem_subject":"choice experiment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"latent classmodel","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Euglena","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"日本におけるユーグレナ食品に関する選択実験 : 学生調査を事例として","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日本におけるユーグレナ食品に関する選択実験 : 学生調査を事例として"},{"subitem_title":"Choice Experiment on Food Containing Euglena in Japan : Evidence from Undergraduate Survey Data","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["96"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-05-30"},"publish_date":"2016-05-30","publish_status":"0","recid":"480","relation_version_is_last":true,"title":["日本におけるユーグレナ食品に関する選択実験 : 学生調査を事例として"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T13:05:51.870409+00:00"}
