Chronicle.com: The research output of faculty members at American colleges appears to be suffering at least in part as a result of declining financial support and scholars’ unwillingness to engage in collaborations with their peers abroad, according to a new analysis of international survey data.The data analysis, discussed this month at the annual conference of the Association for Institutional Research, also concludes that US scholars have less time for and less interest in research than they did before, which is probably contributing to their productivity decline.A rise in the share of US faculty members who are untenured or work part time also may be playing a role because academics who have shaky employment status or are part time probably do not accomplish as much in research as do their tenured or full-time peers.
