A teoria de Callista Roy, a nanda-i e o cuidado ao paciente prostatectomizado

Trata-se de um estudo descritivo de caso clínico, com abordagem qualitativa, o qual possui como objetivo estabelecer relações entre os diagnósticos de enfermagem da NANDA-I e os problemas de adaptação segundo o Modelo Teórico de Roy em um paciente prostatectomizado. A coleta de dados ocorreu em um hospital universitário localizado na cidade de Natal-RN, no mês de janeiro de 2011, por meio de um roteiro de entrevista e exame físico. Os diagnósticos que apresentaram relações entre a NANDA-I e o Modelo de Roy foram: dor, ansiedade, constipação, sono, atividade, volume de líquido e infecção. Conclui-se que grande parte dos problemas adaptativos segundo o Modelo de Roy, manifestados pelos pacientes no pós-operatório de prostatectomia, possuem semelhança com os diagnósticos da NANDA-I

Review of Harvest for Hope: A Guide to Mindful Eating by Jane Goodall with Gary McAvoy and Gail Hudson

One of the world's preeminent experts on primate behavior, author Jane Goodall now invests her boundless energy traveling and speaking about conservation. After years of studying chimpanzees in the Gombe National Park in Tanzania, Goodall found their very existence threatened by poachers, by encroachment of farming into their habitat, and by global forces far from their wild environment. She is now on a mission to inform the public about what is wrong with our society and its impact on the planet. Harvest for Hope catalogs the problems and provides practical solutions.

Eutrophication causes speciation reversal in whitefish adaptive radiations

Species diversity can be lost through two different but potentially interacting extinction processes: demographic decline and speciation reversal through introgressive hybridization. To investigate the relative contribution of these processes, we analysed historical and contemporary data of replicate whitefish radiations from 17 pre-alpine European lakes and reconstructed changes in genetic species differentiation through time using historical samples. Here we provide evidence that species diversity evolved in response to ecological opportunity, and that eutrophication, by diminishing this opportunity, has driven extinctions through speciation reversal and demographic decline. Across the radiations, the magnitude of eutrophication explains the pattern of species loss and levels of genetic and functional distinctiveness among remaining species. We argue that extinction by speciation reversal may be more widespread than currently appreciated. Preventing such extinctions will require that conservation efforts not only target existing species but identify and protect the ecological and evolutionary processes that generate and maintain species.

Divergence along a steep ecological gradient in lake whitefish (Coregonus sp.)

To understand mechanisms structuring diversity in young adaptive radiations, quantitative and unbiased information about genetic and phenotypic diversity is much needed. Here, we present the first in-depth investigation of whitefish diversity in a Swiss lake, with continuous spawning habitat sampling in both time and space. Our results show a clear cline like pattern in genetics and morphology of populations sampled along an ecological depth gradient in Lake Neuchâtel. Divergent natural selection appears to be involved in shaping this cline given that trait specific P(ST)-values are significantly higher than F(ST)-values when comparing populations caught at different depths. These differences also tend to increase with increasing differences in depth, indicating adaptive divergence along a depth gradient, which persists despite considerable gene flow between adjacent demes. It however remains unclear, whether the observed pattern is a result of currently stable selection-gene flow balance, incipient speciation, or reverse speciation due to anthropogenic habitat alteration causing two formerly divergent species to collapse into a single gene pool.

Roy-Steiner equations for piN scattering

In this talk, we present a coupled system of integral equations for the πN → πN (s-channel) and ππ → N̅N (t-channel) lowest partial waves, derived from Roy–Steiner equations for pion–nucleon scattering. After giving a brief overview of this system of equations, we present the solution of the t-channel sub-problem by means of Muskhelishvili–Omnès techniques, and solve the s-channel sub-problem after finding a set of phase shifts and subthreshold parameters which satisfy the Roy–Steiner equations.
