This study is aimed to address the problems associated with questionnaire-based research. Twelve hypothetical cases are presented and checked for ethical validity. The problems are categorized under seven headings: Whether the participation of the subject is truly voluntary; whether consent to participate in the study has been obtained or proxy consent is required; whether consent to participate has been obtained from "authentic" participants and their privacy is protected; whether participants are fully informed before they consent to participate; whether the validity (...) of questionnaire-based research has been determined in terms of its possible harm; how the roles of the research ethics committee are defined; and what content should be presented in reports and articles. It is important that the ethics of questionnaire-based research should be reviewed with consideration to maintaining a balance between the protection of a subject's human rights and the promotion of research for the improvement of medical science and health care.

Recently, null arguments have been treated as an ellipsis phenomenon, derived by PF-deletion or LF-copy under some kind of identity requirements. Focusing on Japanese null arguments, this paper argues that they are base-generated empty nominals which are interpreted via choice functions. The functional approach is supported by cases involving intermediate scope readings, missing antecedents, and implicational bridging. A less standard case of Japanese null arguments anteceded by QPs is also discussed and shown to be amenable to the choice functional analysis (...) supplemented by a general requirement of structural parallelism.
