Self-consistent quantal treatment of decay rates within the perturbed static path approximation

The framework of the Perturbed Static Path Approximation (PSPA) is used to calculate the partition function of a finite Fermi system from a Hamiltonian with a separable two body interaction. Therein, the collective degree of freedom is introduced in self-consistent fashion through a Hubbard-Stratonovich transformation. In this way all transport coefficients which dominate the decay of a meta-stable system are defined and calculated microscopically. Otherwise the same formalism is applied as in the Caldeira-Leggett model to deduce the decay rate from the free energy above the so called crossover temperature $T_0$.Comment: 17 pages, LaTex, no figures; final version, accepted for publication in PRE; e-mail: [email protected]

Development, validation and reliability testing of 'Perinatal Bereavement Care Confidence Scale (PBCCS)'.

Equipping midwives and nurses with confidence to provide bereavement care to parents who have experienced a perinatal loss is vital and impacts on the efficacy of the care received by grieving parents. In education and clinical practice environments there are shortages of bereavement care questionnaires specifically designed to measure midwives' and nurses' confidence and psychosocial factors that impact on their confidence to provide bereavement care. The purpose of the study was to develop a valid and reliable perinatal bereavement care confidence scale (PBCCS). The PBCCS was developed in 4 phases. Phase 1: Questionnaire development, 44 questions were formulated from the literature. Phase 2: Face and content validation of the PBCCS by an Expert Panel. Phase 3: A pilot study was conducted and included 10 cognitive pre-testing interviews and test-retest reliability assessment with a cohort of 26 midwives. Phase 4: Construct validity was assessed using factor analysis with 277 midwives and nurses. In order to avoid confusion with terminologies, the term midwife was used for both nurses and midwives who provided care to bereaved parents and participated in the study. Internal consistency reliability measurement was assessed with Cronbach's alpha. Ethical approval of the study was obtained from four maternity hospitals in Ireland. The PBCCS has 43 items. Bereavement care knowledge (15 items, 3 sub-scales). Bereavement care skills (9 items, 2 sub-scales). Self-awareness (8 items, 2 sub-scales). Organisational support (11 items, 2 subscales). The internal consistency reliabilities ranged from 0.753 to 0.871 except for one subscale 0.663. The PBCCS is a valid and reliable tool with good psychometric properties which can be used to measure midwives' confidence and the psychosocial factors thatimpact on their confidence to provide bereavement care

Exame citológico em medicina veterinária: estudo retrospectivo de 11.468 casos (1994-2008)

Foi realizado um estudo retrospectivo dos resultados dos exames citológicos provenientes dos arquivos do Serviço de Citopatologia do Laboratório de Patologia Animal, Faculdade de Medicina Veterinária e Zootecnia, Universidade Estadual Paulista, Botucatu, São Paulo, entre janeiro de 1994 e dezembro de 2008. Do total de 139.986 animais atendidos no Hospital Veterinário da instituição, 11.468 (8,2%) foram encaminhados para exame citológico. Desses diagnósticos, 57,28% corresponderam a lesões neoplásicas, 19,28% a lesões inflamatórias e 14,79% a processos não neoplásicos (imunológicos, degenerativos, hiperplásicos ou displásicos). Não foi possível concluir o diagnóstico por meio do exame citológico em 7,28% dos casos e não haviam informações diagnósticas registradas em 1,37% dos casos. Dentre os animais que mais receberam indicação para exame citológico destacaram-se os caninos (92,06%), seguidos pelos felinos (4,08%), bovinos (1,77%) e equinos (1,30%). Lesoes neoplásicas foram as mais comumente observadas e foram mais prevalentes nos cães (59,18%), afetando principalmente animais com idade média de 119,60 meses e principalmente fêmeas (61,61%). O incremento anual observado ao longo dos 15 anos de aplicação da citologia demonstra que o exame citológico é um método de suma importância para confirmar, sugerir ou afastar o diagnóstico de diversas afecções, inclusive neoplasia, em todas as espécies animais
