This manuscript is aimed at discussing the plural nature of the main conceptual, theoretical and methodological features of the social representations in their various manifestations. As a base to discuss the topics, we used the main texts that amalgamated the vision of the main researchers of psychology, sociology and nursing. According to Moscovici, social representations correspond to acts of thoughts in which subjects relate to the object, and that object through some process is replaced by symbols, turning it into a representation in the subject's mind. This process involves different mechanisms of contextualization, processing, construction and interpretation by sociocultural and linguistic aspects. In the transdisciplinary perspective, social representations emerge as a multidimensional field that permits questioning the nature of knowledge and the relationship individual-society, implanted in the main post-modern epistemological currents. ASPECTOS TEÓRICOS E METODOLÓGICOS DAS REPRESENTAÇÕES SOCIAISRESUMO: Este estudo convida a refletir sobre a natureza plural dos principais aspectos conceituais, teóricos e metodológicos das representações sociais nas suas diferentes manifestações. Utilizaram-se como base para discussão dos tópicos os principais textos que amalgamam a visão de pesquisadores reconhecidos na Psicologia, Sociologia e Enfermagem. Segundo Moscovici, as representações sociais correspondem a atos de pensamento nos quais os sujeitos se relacionam com o objeto e diante vários mecanismos esse objeto é substituído por símbolos, fazendo com que ele seja representado na mente do sujeito. Esse processo de representação implica diferentes processos de contextualização, transformação, construção e interpretação mediados por aspectos socioculturais e linguísticos. Na perspectiva transdisciplinar, as representações sociais emergem como um campo multidimensional que possibilita questionar a natureza do conhecimento e a relação indivíduo-sociedade, inserindo-se nas principais correntes epistemológicas pós-modernas para criar entidades operativas de comunicação e atuação cotidiana.

Objective: to analyse the differences between medication prescriptions by nurses in Brazil and Ontario, Canada. Methods: a comparative study between two different scenarios; this comparison was not performed between the two countries because Canada does not standardize this practice, which is legally established and is considered as an advanced professional knowledge area in Brazil. Results: prescription is a professional position to be occupied by nurses. However, there is tension surrounding this practice because it is perceived as a threat to privileges or traditions of other health professionals. Prescibing medication by nurses in Brazil and Ontario follows current legislation and training proccess in each context. Conclusions: there are some challenges to be overcome in ensuring the visibility and consolidation of the practice by nurses in these realities: guarantee of professional competence, credibility, acceptability, and the respectability of clientele in your professional scope by other health professionals.

Several methods of population improvement in maize (Zea mays L.) are available, but more information is needed to enable breeders to make the best choice among them. This study was conducted to compare selection among S2 progenies (S2 method) with selection based on testcross performance using inbred testers (TC method) in two populations, FS8A and FS8B. For the TC method, a line from FS8A was the tester used to evaluate S2 lines from FS8B and vice versa. Four cycles of selection were completed, and the selected populations were evaluated over a 4‐yr period. Testing was done at two locations near Gainesville, FL, during both the selection and the evaluation phases. Gains in average combining ability over both populations and all tests were 4.7 and 3.0% cycle−1 for the TC and S2 methods, respectively (significantly different at P = 0.01). Linear regression based on these mean values accounted for 99% of the variation among cycles for each method. The TC method also produced higher predicted yields of populations per se (F = 0) in Cycle 4 (6.85 vs. 6.01 Mg ha−1). On the other hand, the S2 method resulted in a lower rate of yield depression in Cycle 4 for each 1% increase in inbreeding (0.04 vs. 0.06 Mg ha−) and in higher predicted yields of inbred (F = 1) populations (1.70 vs. 0.87 Mg ha−1). These results suggest that nonadditive gene action in the overdominance range is important in these populations because, in the absence of overdominance, the S2 method is expected to be the better procedure.

Objective: Evaluate the contribution of debriefing after clinical simulations for nursing students. Method: Quantitative study, conducted with 35 nursing students who participated in five clinical simulation scenarios with planned debriefings based on the model of the National League Nursing/Jeffries Simulation Theory. After the fifth scenario, students answered the Debriefing Evaluation Scale associated with the Simulation. Results: The items evaluated involved the psychosocial, cognitive, and affective values, and within a scale from one to five, the highest mean was found in cognitive value with 4.23 (±0.56) points, then in psychosocial value with 3.77 (±0.53), and finally in affective value with 3.71 (±0.63) points. Conclusion: The debriefing conducted after the clinical simulation scenarios was a reflective exercise that contributed to the student integrating multiple knowledges in affective, cognitive and psychosocial values, and thus develop the competencies required.

Pesquisa qualitativa com abordagem sócio-histórica que objetivou analisar como se constitui a subjetividade dos indivíduos no contexto da relação família, rua e crack. Os participantes foram 15 moradores de rua da cidade de Florianópolis (SC). A coleta de dados foi realizada de fevereiro a abril de 2013. Os dados foram analisados segundo a Análise de Conteúdo de Bardin. Os resultados destacam que a ausência de regras, limites, comunicação e afeto no núcleo familiar, assim como a violência e o uso/abuso de drogas, foram fatores que colaboraram com o consumo do crack e a moradia de rua. Conclui-se que as relações familiares fragilizadas são um dos fatores de risco corresponsáveis no consumo do crack e a moradia na rua.
