The genes decapentaplegic, wingless, and Distalless appear to be instrumental in constructing the anatomy of the adult Drosophila leg. In order to investigate how these genes function and whether they act coordinately, we analyzed the leg phenotypes of the single mutants and their inter se double mutant compounds. In decapentaplegic the tarsi frequently exhibit dorsal deficiencies which suggest that the focus of gene action may reside dorsally rather than distally. In wingless the tarsal hinges are typically duplicated along with other dorsal structures, confirming that the hinges arise dorsally. The plane of symmetry in double-ventral duplications caused by decapentaplegic is virtually the same as the plane in double-dorsal duplications caused by wingless. It divides the fate map into two parts, each bisected by the dorsoventral axis. In the double mutant decapentaplegic wingless the most ventral and dorsal tarsal structures are missing, consistent with the notion that both gene products function as morphogens. In wingless Distal-less compounds the legs are severely truncated, indicating an important interaction between these genes. Distal-less and decapentaplegic manifest a relatively mild synergism when combined.

Information professionals have traditionally connected people and information resources; however, that role is changing as we move into the knowledge economy. Visioning exercises and thought papers on the future of the profession continue to focus on the resources we manage – moving from paper to digital resources and from physical to digital distribution channels. These visions, though, are short sighted and do not take into account the shift from an industrial and a financial economy to a knowledge economy. In a knowledge economy, individuals with information science skills will play expanded roles beyond the library walls. While intellectual capital and knowledge assets are well understood in the economics and knowledge sciences fields, they are not widely recognized in other domains. This visual presentation reports on the results of Phase 1 of a broader research project to gauge information professionals' awareness of and investment in their own intellectual capital assets. Phase 1 focused on one area of practice – information professionals in academic research libraries – and leveraged a national survey. The survey focused on eight recognized areas of intellectual capital and existing sources of learning and investment. Phase 2 shifts the research focus to narrative descriptions of the use of intellectual capital in the working environment. In Phase 2 individual librarians focus on one of the eight types of intellectual capital and record their experiences using those assets in an electronic journal. Phase 3 will focus on the view of intellectual capital assets from the organizational perspective, i.e., an organization's stock of intellectual capital and the way in which it spends and invests in that capital.

As part of ARL’s Research Library Impact Framework initiative, a research team from the Texas Tech University (TTU) Libraries explored methods for assessing collections related to the study and research of diversity, equity, and inclusion (DEI) topics and their discoverability by users. DEI studies have increased in prominence on academic campuses along with calls to question privilege and power structures, making DEI collections assessment critical. The TTU Libraries undertook a two-part project that surveyed user needs, collections usage, cataloging and discoverability, and user behavior in searching for and evaluating DEI resources. While the researchers were not able to identify an effective method for assessing DEI in large-scale collections, key findings indicate the potential for partnering with women’s and gender studies and Mexican American and Latino/a studies and the need for increased attention on cataloging and metadata, particularly table of contents and abstract/summary fields. The research team identified that many users expressed uncertainty in searching and evaluating DEI resources and expressed interest in search enhancements for better filtering and more prominent website presence for DEI research help.
