    Reaching the boundary between stellar kinematic groups and very wide binaries. II. alpha Lib + KU Lib: a common proper motion system in Castor separated by 1.0 pc

    Aims: I investigate the gravitational binding of a nearby common proper motion system in the young Castor moving group (tau ~ 200 Ma), formed by the bright quadruple star alpha Lib (Zubenelgenubi) and the young solar analog KU Lib. The system has an exceptionally wide angular separation, of about 2.6 deg, which corresponds to a projected physical separation of about 1.0 pc. Methods: I compile basic information of the system and compare its binding energy with those of other weakly bound systems in the field, and study the physical separations of resolved multiple systems in Castor. Results: KU Lib has roughly the same proper motion, parallactic distance, radial velocity, and metallicity than the young hierarchical quadruple system alpha Lib. Besides, KU Lib also displays youth features. The resemblance between these basic parameters and the relatively large estimated binding energy point out that the five stars are gravitationally bound. KU Lib and alpha Lib constitute the widest known multiple system at all mass domains, and likely represent the most extreme example of young wide binaries on the point of being disrupted. Besides, I make a comprehensive compilation of star candidates in Castor, including new ones.Comment: A&A, in press (v2: language edited

    Answering the Calls of "What's Next" and "Library Workers Cannot Live by Love Alone" through Certification and Salary Research

    Members and staff of the American Library Association (ALA) worked diligently over more than a decade to develop a certification program for public library managers. Spurred by a long-standing trend in many other terminal-degree professions that have post-degree, voluntary certifications, the Certified Public Library Administrator Program was born. Legal authority recommended the establishment of a service organization, a 501(c)(6) to manage the program, which has become one of several programs that will be offered to library employees under the imprimatur of ALA. After the American Library Association???Allied Professional Association (ALA-APA) was instituted, advocacy for salary improvement initiatives was appended to the mission. One means of salary advocacy was to improve available data by expanding the scope and usefulness of the ALA Survey of Librarian Salaries, which resulted in the ALA-APA Salary Survey: Non-MLS???Public and Academic, conducted in 2006 and 2007 to collect salary data from more than sixty positions in the field that do not require a master's degree in Library Science. The experience of establishing two certification programs, the Certified Public Library Administrator Program (CPLA??) and the Library Support Staff Certification Program, has been a study in creating new national models of professional development. This article will also discuss the insights that have emerged from fulfilling elements of ALA strategic plans concerning the needs of support staff through certification and the salary survey.published or submitted for publicatio

    Using a Multiple-Case Studies Design to Investigate the Information-Seeking Behavior of Arts Administrators

    Get PDF
    The case study method, and in particular the multiple???case studies design, offers LIS researchers a proven tool for achieving a deep understanding of a specific phenomenon???-for example, the information- seeking behavior of a particular user group. Although the case study method has been dismissed by critics who question the rigor of the approach, numerous studies over the past twenty years have demonstrated that the case study method can be used successfully to probe beneath the surface of a situation and to provide a rich context for understanding the phenomena under study. This article summarizes the application of the multiple???case studies design, in which a literal and theoretical replication strategy is used to identify consistent patterns of behavior and to uncover new and/or divergent themes. The motivation behind arts administrators??? decisions to seek information is investigated using this approach and examples are given of sample selection, data collection, and analysis. Specific issues associated with the case study method are identified and practical steps used to address them are suggested.published or submitted for publicatio
