Landscape scale heterogeneity in the East Turkana ecosystem during the Okote Member (1.56-1.38 Ma).

Placing the biological adaptations of Pleistocene hominins within a well-resolved ecological framework has been a longstanding goal of paleoanthropology. This effort, however, has been challenging due to the discontinuous nature of paleoecological data spanning many important periods in hominin evolution. Sediments from the Upper Burgi (1.98-1.87 Ma), KBS (1.87-1.56 Ma) and Okote (1.56-1.38 Ma) members of the Koobi Fora Formation at East Turkana in northern Kenya document an important time interval in the evolutionary history of the hominin genera Homo and Paranthropus. Although much attention has been paid to Upper Burgi and KBS member deposits, far less is known regarding the East Turkana paleoecosystem during Okote Member times. This study pairs spatially-resolved faunal abundance data with stable isotope geochemistry from mammalian enamel to investigate landscape-scale ecosystem variability during Okote Member times. We find that during this period 1) taxa within the East Turkana large mammal community were distributed heterogeneously across space, 2) the abundance of C3 and C4 vegetation varied between East Turkana subregions, and 3) the Karari subregion, an area with abundant evidence of hominin stone tool manufacture, had significantly more C3 vegetation than regions closer to the central axis of the Turkana Basin (i.e., Ileret and Koobi Fora). These findings indicate that the East Turkana paleoecosystem during the Okote Member was highly variable across space and provided a complex adaptive landscape for Pleistocene hominins.

Disseminated Streptococcus pneumoniae infection involving a ventricular assist device.

We describe the first reported case, to our knowledge, of disseminated pneumococcal infection involving a left ventricular assist device (LVAD). The management of this infection was extremely challenging, requiring multiple surgical debridements, LVAD removal, and prolonged courses of antibiotics. The Streptococcus pneumoniae isolate was found to be serotype 19F, which is included in both the pneumococcal polysaccharide and conjugate vaccines. This report highlights the importance of routine screening for up-to-date vaccination in patients who undergo LVAD implantation.

The meaning of hope and generic caring practices to nurture hope in a rural village in the Dominican Republic.

The purpose of this study was to explore the meaning of hope and generic caring practices to nurture hope among people of a rural village in the Dominican Republic. Ethnonursing methods were used to gather and analyze data from which a definition of hope for this group of people was developed: "Hope is an essential but dynamic life force that grows out of faith in God, is supported by relationships, resources and work, and results in the energy necessary to work for a desired future. Hope gives meaning and happiness." The information obtained also demonstrated that hope interacts with nearly all domains in the Sunrise Model. Generic care practices discovered among this population included working together, advising each other to work hard, and sharing hope itself. Implications for further research are discussed.

Weaving a transcultural thread.

This article describes the development and implementation of an educational strategy to enhance knowledge about transcultural nursing in a College of Nursing undergraduate program. Concepts of diversity and transcultural nursing were integrated into the entire undergraduate curriculum. This content was presented over six quarters in seminar courses throughout the undergraduate program. A team of faculty members developed this series of courses called "Nurse and Society" that included cultural diversity, ethics, professionalism, and policy as strands or threads woven through the courses. Based on faculty evaluations at the end of each course, most graduating students were aware of the need to provide culturally congruent care. However, there is a need to develop a sound programmatic evaluation that includes empirical outcomes of cultural competence among graduates.
