Larval stages of Pyromaia tuberculata (Lockington, 1877) (Decapoda, Majidae, Inachinae) reared in the laboratory

The larval development of Pyromaia tuberculata (Lockington, 1877) is described from specimens reared in the laboratory. Larvae were obtained from ovigerous females collected by trawl in Ubatuba, São Paulo state, Brazil. Rearing was carried out at 24 +/- 1 degrees C in 35 parts per thousand S. The larvae pass through two zoeal stages before moulting to the megalopa. A comparison is made with previously studied majid species occurring in the southern and southeastern regions of Brazil.

A new species of Pterodectes Robin, 1877 (Proctophyllodidae: Pterodectinae) from the pale-breasted thrush, Turdus leucomelas (Passeriformes: Turdidae)

A new species of feather mite, Pterodectes fissuratus sp. n., is described from the pale-breasted thrush, Turdus leucomelas Veillot (Passeriformes: Turdidae), in Brazil. This species is easily distinguished by having numerous well-pronounced lacunae and a longitudinal median furrow on prodorsal and hysteronotal shields in both sexes. Copyright © 2005 Magnolia Press.

Additional observations on the gross morphology and microstructure of Baccaconularia Hughes, Gunderson et Weedon, 2000, a Cambrian (Furongian) conulariid from the north-central USA

Baccaconularia Hughes, Gunderson et Weedon, 2000, from the Furongian Series (Cambrian System) of the north-central USA, has been interpreted as a conulariid cnidarian, based on a suite of gross morphological similarities shared only with other post-Cambrian genera currently assigned to this group. Closely spaced, squarish to subrectangular facial nodes of Baccaconularia are aligned in distinct longitudinal files. Nodes also display a subtler, more or less rectilinear transverse alignment, though this pattern commonly is disrupted by offset parallel to the longitudinal files. In their shape and pattern of arrangement, the nodes of Baccaconularia are most similar to the squarish to elongate nodes of Pseudoconularia Bouček, 1939. Longitudinal node files of Baccaconularia may also be compared with the longitudinal facial ridges of Conularia cambria Walcott, 1890 from the Furongian of Wisconsin. Apical angles of Baccaconularia range from approximately 13° to 14.5°. Scanning electron imaging of B. cf. robinsoni shows that its thin, phosphatic skeleton is finely lamellar, with the thickness of individual lamellae measuring approximately 1 μm. The skeleton also exhibits microscopic circular pores and crater-like pits that range from approximately 5 to 10 μm in diameter. These pores and pits are similar in size, geometry, areal density and pattern of arrangement to those of many post-Cambrian conulariids. Microscopic circular pores are documented here for the first time in the genus Archaeoconularia Bouček, 1939 from the Upper Ordovician of the Czech Republic. Although the origin of the pores and pits is open to alternative interpretations, the discovery of these features and fine lamination in Baccaconularia strengthens the argument that this genus is a Cambrian conulariid. © 2006 Nanjing Institute of Geology and Palaeontology, CAS.

Ultrastructure of the spermatophores and spermatozoa from the gecarcinid land crab, Cardisoma guanhumi Latreille, 1828, (Crustacea, Brachyura, Gecarcinidae) from the western Atlantic

The ultrastructure of the sperm of the gecarcinid land crab Cardisoma guanhumi is described by scanning and transmission electron microscopy. Ultrastructural sperm morphology lends support for the monophyletic origin of the Thoracotremata, and for the placement of C. guanhumi in that clade. Additionally, it further attests the low level of variability within the thoracotreme clade. With regard to ultrastructural morphology, small differences concerning the apical button, the hyaline periopercular rim, the inner acrosome zone, and the outer two lamellations in the outer acrosome zone have been found between the spermatozoa of C. guanhumi and Cardisoma carnifex, the only other species in this genus studied for spermatozoal morphology.

Acquisition of suture skills during medical graduation by instructor-directed training: A randomized controlled study comparing senior medical students and faculty surgeons

Due to shortage of time and limited availability of faculty surgeons to teach basic surgical skills during medical graduation, the search for alternative ways of simulated training with feedback is needed. The purpose of this study was to compare the simulated teaching of suture skills to novice medical students by senior medical students and by experienced faculty surgeons. Forty-eight novice medical students were randomly assigned to three practice conditions on bench model (n = 16): self-directed suture training (control), senior medical student-directed suture skills' training, or experienced faculty surgeon-directed suture skills' training. Pre- and post-tests were applied. Global Rating Scale with blinded evaluation and self-perceived confidence based on Likert scale were used to assess all suture performances in pre- and post-training. Effect size was also calculated. The analysis made after training showed that the students who received feedback from the instructors had better performance based on the Global Rating Scale (all p < 0.0000) and felt more confident to carry out sutures (all p < 0.0000) when compared to the control. There was no significant difference (all p > 0.05) between the student-directed teaching and faculty-directed teaching groups. The magnitude of the effect (instructor-directed training suture) was considered large (>0.80) in all measurements. The acquisition of suture skills after student-directed training was similar to the training supervised by faculty surgeon, and the increase in suture performances of trainees that received instructor administered training was superior to self-directed learning. © 2013 Springer-Verlag Italia.

The meaning of evidence-based management to brazilian senior nurse leaders

Purpose: The study objective was to understand the meaning of evidence-based management for senior nurse leaders in accredited, public hospitals in the State of Sao Paulo, Brazil. Design and Method: A phenomenological approach was used to analyze interviews conducted with 10 senior nurse leaders between August 2011 and March 2012. The analytic method was developed by the Brazilian phenomenologist, Martins. Findings: Senior nurse leaders described how they critically appraise many sources of evidence when making managerial decisions. They emphasized the importance of working with their teams to locally adapt and evaluate best evidence associated with managerial decision making and organizational innovations. Their statements also demonstrated how they use evidence-based management to support the adoption of evidence-based practices. They did not, however, provide specific strategies for seeking out and obtaining evidence. Notable challenges were traditional cultures and rigid bureaucracies, while major facilitators included accreditation, teamwork, and shared decision making. Conclusions: Evidence-based management necessitates a continuous process of locating, implementing, and evaluating evidence. In this study leaders provided multiple, concrete examples of all these processes except seeking out and locating evidence. They also gave examples of other leadership skills associated with successful adoption of evidence-based practice and management, particularly interdisciplinary teamwork and shared decision making. Clinical Relevance: This study demonstrates senior nurse leaders' awareness and utilization of evidence-based management. The study also suggests what aspects of evidence-based management need further development, such as more active identification of potential, new organizational innovations. © 2013 Sigma Theta Tau International.

A pesca do tamoatá Haplosternum litorale (Hancock, 1828) (Siluriformes : Callichthyidae), na ilha de Marajó-Foz Amazônica

Hoplosternum littorale (Hancock, 1828) (Siluriformes, Callichthyidae) é um peixe de médio porte, conhecido na Amazônia brasileira como tamoatá, sendo o principal recurso pesqueiro da ilha de Marajó. A pesca do tamoatá é realizada de forma artesanal, principalmente na região do lago Arari, Município de Santa Cruz do Arari, sendo que sua comercialização nos centros urbanos é feita por intermédio de barcos conhecidos como geleiras. O objetivo deste trabalho foi descrever os aspectos da pesca do tamoatá na ilha de Marajó e relacionar a abundância desta espécie com os dias gastos pelas geleiras para completar a sua carga e com a quantidade de chuva. A pesca artesanal comercial do tamoatá é aqui descrita com base em observações de campo e entrevistas com pescadores, sendo realizada basicamente por redes de arrasto e no período de estiagem, quando o nível da água do rio e do lago Arari está baixo. A estimativa de abundância do tamoatá na ilha de Marajó foi baseada na relação entre o total desembarcado no porto do Ver-O-Peso, em Belém, e o número de dias que os barcos geleira esperam para encher suas urnas. A precipitação foi medida pela estação meteorológica de Soure, situada na porção leste da ilha de Marajó. A análise de covariância (ANCOVA) dos dados mensais referentes aos anos 1994 a 2004 apontou uma relação significativa entre estas variáveis, sendo o total desembarcado apresentando-se diretamente proporcional ao número de dias-geleiras e inversamente proporcional à chuva mensal. Por outro lado, observou-se ainda uma relação significativa entre o volume de chuva anual e o peso total de pescado capturado. Esta relação parece explicar a diminuição do desembarque do tamoatá nos dois períodos amostrados.
