Bandwidth and density for block graphs

The bandwidth of a graph G is the minimum of the maximum difference between adjacent labels when the vertices have distinct integer labels. We provide a polynomial algorithm to produce an optimal bandwidth labeling for graphs in a special class of block graphs (graphs in which every block is a clique), namely those where deleting the vertices of degree one produces a path of cliques. The result is best possible in various ways. Furthermore, for two classes of graphs that are ``almost'' caterpillars, the bandwidth problem is NP-complete.Comment: 14 pages, 9 included figures.

Implementing a Practice Doctorate Program at a Distance through an Urban-Rural Partnership

The purposes of this poster presentation are to 1) describe the implementation of a doctor of nursing practice (DNP) program by providing access to rigorous distance education to students living in rural Pennsylvania; 2) discuss building a critical mass of doctorally prepared advanced practice nurse experts in both urban and rural communities; and 3) share formative and summative evaluation information. Through funding from the U.S. Department of Health and Human Services, Health Resources and Services Administration, Bureau of Health Professions, Division of Nursing, the Jefferson School of Nursing (JSN) expanded its DNP program currently offered at the urban Philadelphia campus to the rural campus in Danville. Using the methodologies of live web-casting and live video over the Internet, distance students are afforded the opportunity to participate in a live classroom setting rather than experience the static distance methodology of reading through lectures themselves. For example, during the applied biostatistics course, the faculty teaches onsite in Philadelphia projecting the SPSS and the database on screen so that students on both campuses can simultaneously view, hear, and interact with the discussion. There is a doctorally prepared faculty member onsite in Danville as a resource for the students. These newer technologies make possible real-time faculty-student dialogue, student-to-student dialogue, and enhance socialization. Furthermore, the use of advanced technologies allows distance students to discuss with peers and faculty alike, in real time, the problems, successes, and questions which arise during class and clinical practica, thereby enhancing critical thinking and diagnostic reasoning skills. This unique urban-rural partnership, made possible through advanced technologies, addresses increasing demands for educating greater numbers of doctorally prepared advanced practice nurses to work in north and central rural Pennsylvania, thus promoting access to health care in rural underserved communities. Other than in academia, there are no doctorally prepared advanced practice nurses employed in practice in the area

Excavations in the Archaic Civic Buildings at Azoria in 2005-2006

Continuing excavation on the South Acropolis at Azoria in northeastern Crete has exposed buildings of Archaic date (7th–early 5th century b.c.) that served communal or public functions. Work conducted in 2005 and 2006 completed the exploration of Late Archaic levels within the Communal Dining Building (putative andreion complex), the Monumental Civic Building, and the adjacent Service Building. These contexts and their assemblages, especially the animal and plant remains, permit the characterization of diverse dining practices and the interpretation of patterns of food production and consumption. Both the Communal Dining Building and the Monumental Civic Building show extensive evidence of communal feasting and the integration of cult

Development and implementation of a workshop for young adults with diabetes entering college and the workforce

The process of transitioning from pediatric to adult diabetes care for adolescents and young adults is challenging. This transition period may include many life changes, and can be fraught with worsening glycemic control leading to increased risk for diabetes-related hospitalizations and complications. Research has demonstrated that increased support during this period can help maintain engagement in diabetes care. Transition guidelines highlight the importance of preparation and readiness for transition. In this article, we discuss the development, implementation and content of a workshop for patients and parents/caregivers preparing for the transition to college, the workforce and adult diabetes care

Excavations at Azoria, 2002

This report summarizes the results of the first season of excavation at Azoria in eastern Crete and provides an overview of the project's goals and problem orientation. Work in 2002 concentrated on the peak of the South Acropolis and the occupational phases of the seventh-sixth centuries B.C. The recovery of a possible andreion complex suggests the urban character of the site in the sixth century and forms a starting point for discussing the political economy of the Archaic city. The excavations revealed important evidence for the organization of the sixth-century settlement and for the complex stratigraphic history of the site, including the Final Neolithic, Late Prepalatial, Early Iron Age, Archaic, and Hellenistic periods

Navigating distance learning technologies using team teaching

In 2004, the American Association of Colleges of Nursing (AACN) adopted the position to move the current level of preparation necessary for advanced practice nurse (APN) roles from the master\u27s degree to the doctoral level. AACN also called for educating APNs and other nurses seeking top leadership and clinical roles in Doctor of Nursing Practice (DNP) Programs. In September 2007, the Jefferson School of Nursing welcomed its first cohort of 18 DNP students. Students represented a wide variety of practice specialties including acute care, primary care, healthcare administration, population health, education and industry. Twenty students comprise the second cohort entering in September 2008. Nationwide, Jefferson is one of 79 schools of nursing offering a DNP degree
