Planning nursing teaching: Educational purposes and clinical competence

Thinking about nursing education implies articulating this issue with the expressions of theoretical frameworks, from the perspective of a pedagogical aspect that includes both constructivism and competencies. The objective was to characterize, from a longitudinal view, the construction of care competencies that exist in the teaching plans of nursing undergraduate programs. This exploratory-descriptive study used a qualitative approach. Documentary analysis was performed on the nine teaching plans of undergraduate care subjects. The ethical-legal aspects were guaranteed, so that data was collected only after the study had been approved by the Research Ethics Committee. The data evidenced a curriculum organization centered on subjects, maintaining internal rationales that seem to resist summative organizations. Signs emerge of hardly substantial links between any previous knowledge and the strengthening of critical judgment and clinical reasoning. As proposed, the study contributed with reconsiderations for the teachinglearning process and showed the influence of constructivism on the proposal of clinical competencies.

Effect of superstimulatory treatments on the expression of genes related to ovulatory capacity, oocyte competence and embryo development in cattle.

Multiple ovulation (superovulation) and embryo transfer has been used extensively in cattle. In the past decade, superstimulatory treatment protocols that synchronise follicle growth and ovulation, allowing for improved donor management and fixed-time AI (FTAI), have been developed for zebu (Bos indicus) and European (Bos taurus) breeds of cattle. There is evidence that additional stimulus with LH (through the administration of exogenous LH or equine chorionic gonadotrophin (eCG)) on the last day of the superstimulatory treatment protocol, called the 'P-36 protocol' for FTAI, can increase embryo yield compared with conventional protocols that are based on the detection of oestrus. However, inconsistent results with the use of hormones that stimulate LH receptors (LHR) have prompted further studies on the roles of LH and its receptors in ovulatory capacity (acquisition of LHR in granulosa cells), oocyte competence and embryo quality in superstimulated cattle. Recent experiments have shown that superstimulation with FSH increases mRNA expression of LHR and angiotensin AT(2) receptors in granulosa cells of follicles >8 mm in diameter. In addition, FSH decreases mRNA expression of growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) in oocytes, but increases the expression of both in cumulus cells, without diminishing the capacity of cumulus-oocyte complexes to generate blastocysts. Although these results indicate that superstimulation with FSH is not detrimental to oocyte competence, supplementary studies are warranted to investigate the effects of superstimulation on embryo quality and viability. In addition, experiments comparing the cellular and/or molecular effects of adding eCG to the P-36 treatment protocol are being conducted to elucidate the effects of superstimulatory protocols on the yield of viable embryos.

Moral judgment competence of medical students: a transcultural study

The authors conducted a cross-sectional short-term study using Lind's Moral Judgment Test (MJT) to compare moral judgment competence (C-score) among students from a medical school in the Northeast region of Brazil and a medical school in the Northern region of Portugal. This study compares the C-scores of groups in the first and eighth semesters of study within each medical school and groups from corresponding semesters between the two medical schools. This study also evaluates the influence of such factors as age and gender on moral competence. A regression of moral judgment competence among the students in their eighth semester versus the students in the first semester of Brazilian medical school (p < 0.001) and a stagnation of moral competence among students in their eighth semester versus the first semester students in the Portuguese medical school (p = 0.06) were observed. For both the first semester and eighth semester groups, the students in the Portuguese medical school had higher C-scores than the students in the Brazilian medical school. In the analysis of the students' performances in terms of MJT dilemmas, the phenomenon of moral segmentation was observed in all of the groups, and the students performed better on the worker's dilemma than on the doctor's dilemma. Among students in the same semester of study, older students had lower C-scores. There was generally no significant difference between men's and women's C-scores. © 2013 Springer Science+Business Media Dordrecht.

Ambigüidade lexical

O trabalho procura conceituar homonímia e poüssemia, do ponto de vista sincrônico, reunindo as orientações de Mattoso Câmara Jr. e B. Pottier. E quer mostrar a confluência de ambos os fatos para a ambigüidade da frase, como riqueza de expressão em diversos textos, de cunho literário e popular.

A inferência lexical no texto técnico em inglês

O objetivo deste trabalho é investigar a estratégia de inferência lexical de palavras-chave em textos técnicos de língua inglesa. Os sujeitos da pesquisa são alunos de um curso técnico de Eletrônica, falsos principiantes na língua estrangeira. A análise dos dados é quantitativa e qualitativa. A pesquisa observa o papel do conhecimento prévio dos sujeitos sobre assuntos específicos e as pistas contextuais oferecidas pelo autor de textos técnicos, na inferência lexical. As categorias de familiarização lexical estudadas são: explicação, definição, exemplificação, ilustração, estipulação e sinonímia. Os resultados demonstram uma certa preponderância das estratégias de uso do conhecimento prévio sobre as de uso de pistas contextuais, embora a pesquisa tenha constatado que a interação das duas estratégias seja importante para que a inferência lexical seja produzida com maior sucesso.

Molecular Evaluation of Developmental Competence of Oocytes Collected In Vivo from Buffalo and Bovine Heifers during Winter and Summer

Buffaloes and bovines are polyestrous and seasonal or annual livestock, respectively, that show reduced fertility during heat stress. To investigate whether reduced fertility is related to oocyte competence in both species, immature oocytes from buffalo and bovine heifers were collected during winter and summer and subjected to molecular analyses. In each season, heifers of both species had their follicular wave emergence synchronized with a standard protocol (Ferreira et al., 2011). Before being subjected to ovum pick up (OPU), cutaneous (CT; degrees C) and rectal (RT; degrees C) temperatures and respiratory rate (RR; breaths/min) were measured. Oocytes' RNA was extracted to evaluate the expression of target genes related to mtDNA replication/transcription (PPARGC1A, TFAM and MT-CO1), apoptosis (BAX and BCL2) and HS (HSP90AA1 and HSPA1AB). ACTB, HIST1H2AG and GAPDH were initially chosen as housekeeping genes. In buffaloes, CT (35.0 +/- 0.4 vs 23.8 +/- 0.5), RT (38.7 +/- 0.1 vs 38.0 +/- 0) and RR (21.3 +/- 1.2 vs 15.4 +/- 1.1) were higher during summer than winter. However, in bovine heifers, RT (38.7 +/- 0.1 vs 38.6 +/- 0.1) and RR (44.8 +/- 1.5 vs 40.6 +/- 1.5) were similar in both seasons, while CT (31.6 +/- 0.3 vs 30.2 +/- 0.3) was increased during summer. Reduced expression of ACTB, HIST1H2AG and GAPDH was evidenced during summer, disqualifying them as housekeeping genes. Similarly, the expression of all target genes was reduced during summer in oocytes of both species. In summary, physiological responses to heat stress seem to be more intense in buffalo than bovine heifers. However, in both species, negative effects of heat stress upon oocyte quality occur at the molecular level and affects genes related to several biological functions.
