The issues addressed in philosophical papers on quotation generally concern only a particular type of quotation, which I call ‘closed quotation’. The other main type, ‘open quotation’, is ignored, and this neglect leads to bad theorizing. Not only is a general theory of quotation out of reach: the specific phenomenon of closed quotation itself cannot be properly understood if it is not appropri...

It appears that in mixed quotations like the following, the quoted expression is used and mentioned at the same time: George says Tony is his ‘bestest friend’. Most theories seek to account for this observation by assuming that mixed quotations operate at two levels of content at once. In contradistinction to such two-dimensional theories, we propose that quotation involves just a single level ...

Pure uses are governed by a simple rule: by enclosing any expression within quotation marks one gets a singular term, the quotation, that stands for the enclosed expression. Impure uses are far less simple. In a series of use...

We present a novel model for due date quotation. Jobs arrive at a single server or m-machine flow shop over time. Upon arrival, the processing times on each machine of the job are known, and due dates must be quoted for each job. The jobs are sequenced on the machines without preemption. Associated with each job, there are three measures of disadvantages to the inventory cost and the service le...

We discuss two kinds of quotation, namely indirect quotation (e.g., ‘Anita said that Mexico is beautiful’) and pure quotation (e.g., ‘Mexico’ has six letters). With respect to each, we have both a negative and a positive plaint. The negative plaint is that the strict Davidsonian (1968, 1979a) treatment of indirect and pure quotation cannot be correct. The positive plaint is an alternative accou...

This communication is based on an original approach linking economical factors to technical and methodological ones. This work is applied to decision process for mix production. This approach is relevant for costing driving system. The main interesting point is that the quotation factors (linked to time indicators for each step of the industrial process) allow the complete evaluat ion and contr...
