The Arabidopsis TCH genes were discovered as a consequence of their marked upregulation of expression in response to seemingly innocuous stimuli such as touch. Further analyses have indicated that these genes are upregulated by a variety of diverse stimuli. Understanding the mechanism(s) and factors that control TCH gene regulation will shed light on the signaling pathways that enable plants to respond to changing environmental conditions. The TCH proteins include calmodulin, calmodulin-related proteins and a xyloglucan endotransglycosylase. Expression analyses and localization of protein accumulation indicate that the potential sites of TCH protein function include expanding cells and tissues under mechanical strain. We hypothesize that the TCH proteins may collaborate in cell wall biogenesis.
The need for better financial reporting by public sector entities as a means towards greater accountability has been widely canvassed. This paper discusses the development and application of accounting standards in Australia in this context. The responses of the accounting profession, through its standard setting process, and of the Commonwealth and several State governments are described and the conclusion reached that these developments will mean significant improvement in the information content of public sector financial reports.
The Internet provides new opportunities for aviation firms to develop decision support systems that take advantage of the wealth of detailed online pricing and product information. Although the airline industry has been able to incorporate large volumes of these data systematically into its business models, the academic community has generally conducted its analyses on a small set of nonrepresentative markets. The challenges and opportunities facing researchers who want to collect large volumes of data from airline websites and travel agencies are discussed. Several case studies are used to highlight the types of research questions that can be investigated with this type of data, including how average prices and price dispersion evolve in U.S. markets. A new sample design is proposed to enable researchers to investigate effects caused by carriers’ pricing strategies and multiairport competition.
One important focus of the libraries’ work in recent years has been transforming the work of subject librarians to foster the development of “strong, collaborative, opportunistic relationships that place Ohio University (OU) Libraries in the flow of teaching, learning, and research.” Librarians seek to be experts embedded in the disciplines, collaborating and partnering with faculty as part of the academic enterprise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
