A paradox that an anomalous \u2018resistivity\u2019 contributes to acceleration of electrons is resolved by taking into account its different effects on electrons in different parts of the distribution function (Papadopoulos: Rev. Geophys. Space Phys., 15\uff0c113\uff0c1977); bulk electrons carrying a field-aligned current are anomalously scattered and decelerated by collisions with turbulent electrostatic waves and contribute to maintain parallel electric field\uff0cwhich in turn accelerates electrons in the tail of the distribution. Among the possible instabilities the electrostatic ion cyclotron instability has the lowest threshold velocity for the wide range of Te/Ti including Te/Ti\uff5e1\uff0cwhich is valid in the upper ionosphere. The electrostatic ion cyclotron wave is destabilized by a relatively small field-aligned current in the upper ionosphere (Kindel and Kennel: J. Geophys. Res., 76\uff0c3055, 1971). A numerical model of the field-aligned acceleration by Sato (Symposium on Plasma Waves in the Magnetosphere, 66, 1978) is reviewed in order to emphasize an important role of the ionosphere; the existence of a resistive external circuit (ionosphere) is necessary for resolving the \u2018chicken-egg\u2019 cause and effect relationship among parallel electric field\uff0c anomalous resistivity and formation of runaway (accelerated) electrons precipitating downward into the ionosphere.", "subitem_description_type": "Abstract"}]}, "item_2_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "1738", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Miura, Akira"}]}]}, "item_2_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u56fd\u7acb\u6975\u5730\u7814\u7a76\u6240"}]}, "item_2_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u56fd\u7acb\u6975\u5730\u7814\u7a76\u6240"}]}, "item_2_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00181831", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00857289", "subitem_source_identifier_type": "ISSN"}]}, "item_2_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "450", "subitem_subject_scheme": "NDC"}]}, "item_2_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "National Institute of Polar Research"}]}, "item_2_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Journal Article"}]}, "item_2_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u6771\u4eac\u5927\u5b66\u7406\u5b66\u90e8\u5730\u7403\u7269\u7406\u7814\u7a76\u65bd\u8a2d"}, {"subitem_text_value": "Geophysics Research Laboratory, University of Tokyo"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u4e09\u6d66, \u5f70"}], "nameIdentifiers": [{"nameIdentifier": "1737", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-05-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Anomalous-Resistivity.pdf", "filesize": [{"value": "2.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2200000.0, "url": {"label": "Anomalous-Resistivity.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/513/files/Anomalous-Resistivity.pdf"}, "version_id": "21573d1b-5a7b-44d2-b54a-d257f641852a"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u7570\u5e38\u62b5\u6297\u306b\u3088\u308b\u6cbf\u78c1\u529b\u7dda\u52a0\u901f : Review", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u7570\u5e38\u62b5\u6297\u306b\u3088\u308b\u6cbf\u78c1\u529b\u7dda\u52a0\u901f : Review"}]}, "item_type_id": "2", "owner": "1", "path": ["9/10/11", "75/121/122"], "permalink_uri": "http://hdl.handle.net/2261/42754", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2011-02-22"}, "publish_date": "2011-02-22", "publish_status": "0", "recid": "513", "relation": {}, "relation_version_is_last": true, "title": ["\u7570\u5e38\u62b5\u6297\u306b\u3088\u308b\u6cbf\u78c1\u529b\u7dda\u52a0\u901f : Review"], "weko_shared_id": null}
