The conclusions drawn from this study include findings such as that, in the case of e-books, which have both aspects of a transition from existing technology to new technology and the creation of a new technical field, they resemble a logistic model, characterized by starting out slow and a long period of time until critical mass is reached,and that such a slow start is only natural since it involves a significant change in human history,constituting a change from the physical to the non-physical for the first time in the long history of books going back more than five thousand years.", "subitem_description_type": "Abstract"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "植田, 康孝"}, {"creatorName": "ウエダ, ヤスタカ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "44", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "UEDA, Yasutaka", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "45", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2013-12-13"}], "displaytype": "simple", "download_preview_message": "", "file_order": 0, "filename": "ueda_22.pdf", "filesize": [{"value": "2.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2400000.0, "url": {"label": "Diffusion Models of E-Books", "url": "https://edo.repo.nii.ac.jp/record/36/files/ueda_22.pdf"}, "version_id": "4978827f-7b22-4b77-aa7e-a7f9c1278f50"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Epidemic model", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Probit model", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Logistic model", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Bass model", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Network externality", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Critical", "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": "Diffusion Models of E-Books", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Diffusion Models of E-Books", "subitem_title_language": "en"}]}, "item_type_id": "10002", "owner": "15", "path": ["6"], "permalink_uri": "https://edo.repo.nii.ac.jp/records/36", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2013-12-13"}, "publish_date": "2013-12-13", "publish_status": "0", "recid": "36", "relation": {}, "relation_version_is_last": true, "title": ["Diffusion Models of E-Books"], "weko_shared_id": -1}
