without one = ?

Context:

The best opportunity to revive Chinese publishing, whether in Chinese or English, probably lies in an open-access platform -- increaingly popular in Western journals. Many Chinese journals already charge authors a publication fee, so should be able to make a smooth transition to the open-access model, in which they are supported by fees rather than by subscription revenues. Making content freely available would help to popularize journals, and would encourage them to develop an online presence. Too many operate without one, enjoying a captive audience at their home institutions and lacking any competitive spur to bring themselves up to speed on Internet publishing. The government could provide the interest, investment and expertise to bring these publishers into the twenty-first century.
