The investigative interviewing of eyewitnesses is an important part of the judicial system and is essential in police investigations to identify culpable parties. However, interviewing witnesses to elicit accurate recall is not without some flaws (Ainsworth, 2002). Researchers have acknowledged that recall of information is a complex process vulnerable to variables which impede the retrieval of accurate information (Gudjonsson, 1996; Loftus, 1979; 1992). To improve witness recall, psychologists developed the Cognitive Interview (CI) procedure to help interviewers retrieve more correct information from witnesses (Fisher & Geiselman, 1992). The use of the CI has been shown to increase accuracy in many populations (Memon, Holley, Wark, Bull, & Koehnken, 1996; Milne & Shaw, 1999). However, there are some criticisms of the CI. For example, the CI may cause confusion for witnesses (Kebbell, Milne, & Wagstaff, 1999), takes longer to administer than a standard police interview (Croft, 1995) and contain components which are reported to undermine the effectiveness of this procedure (Boon & Noon, 1994). This research program utilised three studies in a multimethod approach to evaluate investigative interviewing procedures, from an experimental and applied perspective. The overarching aim of this research was to identify a parsimonious, effective and efficient interview procedure which overcame some of the limitations recognized in the CI. The first study employed an experimental methodology to test the effectiveness of the CI and two alternative versions of the CI, to determine which interview procedure resulted in the most correct and least incorrect amounts of information being elicited from student witnesses to a road incident stimulus. Results indicated that the truncated group utilizing mnemonics Tell All and Reinstate Context elicited as much correct and less incorrect information than the ‘Full CI’ group, and took less time to administer. Study Two examined the perceptions of the interview procedure from the witnesses’ perspective. Witnesses were asked to complete a questionnaire which was designed to investigate what the participants thought about how the interview was conducted. Results indicated that, overall, the witnesses found that the interviewers engaged in practices and behaviours at a similar skill level and appreciated the rapport building and clarity of the interviewers. A content analysis revealed that the witnesses favoured some mnemonics over others. The qualitative statements made in regard to questions in the questionnaire are presented. Study Three used a triangulation methodology to determine what the Queensland Police Service officers were currently trained in and practising in the field. Secondary sources, a questionnaire, focus group and case study methodologies were used to make this determination. Findings indicated that there were areas where the police service could improve training of officers to help facilitate interviewing of witnesses. The integration of the findings from the three studies will help to inform the current state of research in the area of investigative interviewing. In particular, this research provides a target examination of interviewing practices in a sub-section of the Queensland Police Service. The findings from the three studies were used to identify an interview procedure which obtained more correct information, did not gain an increase in incorrect information, reduced the time required to conduct the interview, was not confusing for the witnesses, or the officers, and contained no inherent problems for the judicial system. Further recommendations are made for the use of interview protocols for investigative interviewing of road incidents.

Calls for history teachers to adopt inquiry methods continue to go unabated in educational research and curricular initiatives. In recent years, there has been increased recognition of the important role teacher reflection plays in managing the uncertainty that accompanies such pedagogy in history classrooms. Accordingly, this dissertation was situated within theories of reflection and reflective teaching, which acknowledge teaching to be endemically problematic and teachers as autonomous in their curricular- instructional decisions and thereby resistive to certainty-driven models of history teaching. This dissertation sought to investigate the reflections of inquiry-oriented history teachers by examining how and upon what they reflect throughout a unit of study. Using an interpretive multiple-case design with video-stimulated recall methodology, reflective interviews were conducted with participants in four different schools within the same urban public school district. A cross-case analysis of the data led to several key findings. First, the process of reflection for teachers in practice revealed itself to be more affective and messy than conventional rational models of reflection found in the literature. Second, the results showed that history teachers’ reflections were prioritized in accordance with their values and sense of purpose. Third, the inclusiveness of teachers’ classroom environments and curricular-instructional decisions were a focal point of their reflections. Fourth, the teachers’ reflections were influenced by their understandings of their school cultures, with three of the four teachers finding their school norms and policies as oppositional to the promotion of inquiry methods with their students. Finally, the findings showed that reflection aided teachers’ examination of assumptions embedded within their professional routines and pedagogical decisions, particulary with regard to the selection and use of the essential questions that framed their units. This dissertation highlights the need for more and better reflective opportunites for pre- and in-service history teachers and for better research that might yield further insights into the nature of inquiry-based history teaching.

En el presente artículo, el autor realiza un análisis del fenómeno económico llamado recall, así como también de las consecuencias jurídicas que surgen de este. Para cumplir con dicha tarea, se nos presenta la posición que se ha tomado en el Derecho Comparado, para después hacer un parangón con la forma en la que el recall ha sido tratado por INDECOPI en el Perú. Finalmente, el autor emprende una propuesta sobre cómo debería estar regulado el recall en nuestro ordenamiento. In this paper, the author analyzes the economic phenomenon known as “recall”, as well as the legal consequences that arise from it. To fulfill this task, the author first introduces the stance accepted in Comparative Law, and then compares it with the way in which the “recall” has been dealt with by INDECOPI in Peru. Finally, the author presents a proposal as to how the “recall” should be regulated in our legal system.

Objetivos: Quantificar a ingestão dietética de adultos portadores de hepatopatia crônica correlacionando-a ao estado nutricional, e comparar diferentes métodos de avaliação nutricional nesta população, especialmente métodos de avaliação funcional (dinamometria - FAM - e espessura do músculo adutor do polegar - MAP) e a avaliação global do Royal Free Hospital (RFH-GA). Materiais e métodos: Foram avaliados 97 pacientes ambulatoriais do Hospital de Clínicas de Porto Alegre, com diagnóstico de hepatopatia crônica (41 hepatite crônica – HCr - e 56 cirróticos - CIR) entre abril de 2009 e janeiro de 2010. Foi realizada avaliação nutricional através de inquérito alimentar (R24h), antropometria - Índice de massa corporal (IMC) e circunferência muscular do braço (CMB), avaliação subjetiva global (ASG), FAM, RFH-GA e MAP. Resultados: Pacientes do grupo HCr apresentaram maior ingestão calórica total (p=0,005) e maior ingestão proteica (p<0,0001) que os pacientes CIR. Houve relação entre RFH-GA (p<0,001) e FAM (p<0,05) e ingestão de calorias e proteínas. A prevalência de desnutrição no grupo HCr e no grupo CIR foi, de acordo com RFH-GA (51,2 vs 84% - p=0,002), FAM (61 vs 82,1% - p=0,02), ASG (14,6 vs 32,1% - p=0,048), MAP (7,3vs 14,3% - p=NS), CMB (4,9 vs 14,3% - p=NS) e IMC (2,4 vs 3,6% - p=NS). Houve concordância moderada entre FAM e RFH-GA (k=0,43). Conclusão: Pacientes portadores de hepatopatia crônica, mesmo não cirróticos, têm ingestão energética e proteica inadequadas. Desnutrição é frequente nos dois grupos, especialmente na cirrose. FAM e RFH-GA são os métodos que identificaram maior prevalência de desnutrição nesta população e apresentam concordância entre si. A ingestão insuficiente de calorias e proteinas foi associada ao diagnóstico de DPC pela RFH-GA e FAM. / Background/aims: Objectives: To quantify the dietary intake of adults with chronic liver disease and correlate the nutritional status. Compare different methods of nutritional assessment in this population, in special methods of functional evaluation (hand grip streght – HG and The thickness of the adductor pollices muscle - APM) and the Royal Free Hospital global assessment (RFH-GA). Methods: 97 patients at the Hospital de Clinicas de Porto Alegre, diagnosed with chronic liver disease (41 chronic hepatitis - CH - and 56 cirrhotic - CIR) between April 2009 and January 2010 was assessed. Nutritional assessment was carried out by dietary recall (24HR), anthropometry (body mass index - BMI - body and arm muscle circumference - AMC), subjective global assessment (SGA), HG, RFH-GA and APM. Results: CH group patients had higher total caloric intake (p = 0.005) and higher protein intake (p <0.0001) than patients CIR. There was a relationship between the RFH-GA (p <0.001) and HG (p <0.001) and intake of calories and proteins. The prevalence of malnutrition in the CH group and the CIR group was by RFH-GA (51.2 vs. 84% - p = 0.002), HG (61 vs 82.1% - p = 0.02), SGA (14.6 vs. 32.1% - p = 0.048), APM (7.3 vs 14.3% - p> 0.05), MAC (4.9 vs 14.3% - p> 0.05) and BMI (2.4 vs. 3.6% - p> 0.05). There was moderate agreement between HG and RFH-GA (k = 0.43). Conclusion: Patients HC and CIR have energy and protein intake inadequate. Malnutrition is common in both groups, especially in the second. RFH-GA and HG are the best methods to identify malnutrition in this population and usually correlate with each other. The insufficient intake of calories and protein contributed to the diagnosis of malnutrition by RFH-GA and HG.

Os mecanismos tradicionais de consulta a bases de dados, que utilizam o critério de igualdade, têm se tornado ineficazes quando os dados armazenados possuem variações tanto ortográficas quanto de formato. Nesses casos, torna-se necessário o uso de funções de similaridade ao invés dos operadores booleanos. Os mecanismos de consulta por similaridade retornam um ranking de elementos ordenados pelo seu valor de similaridade em relação ao objeto consultado. Para delimitar os elementos desse ranking que efetivamente fazem parte do resultado pode-se utilizar um limiar de similaridade. Entretanto, a definição do limiar de similaridade adequado é complexa, visto que este valor varia de acordo com a função de similaridade usada e a semântica dos dados consultados. Uma das formas de auxiliar na definição do limiar adequado é avaliar a qualidade do resultado de consultas que utilizam funções de similaridade para diferentes limiares sobre uma amostra da coleção de dados. Este trabalho apresenta um método automático de estimativa da qualidade de funções de similaridade através de medidas de revocação e precisão computadas para diferentes limiares. Os resultados obtidos a partir da aplicação desse método podem ser utilizados como metadados e, a partir dos requisitos de uma aplicação específica, auxiliar na definição do limiar mais adequado. Este processo automático utiliza métodos de agrupamento por similaridade, bem como medidas para validar os grupos formados por esses métodos, para eliminar a intervenção humana durante a estimativa de valores de revocação e precisão. / Traditional database query mechanisms, which use the equality criterion, have become inefficient when the stored data have spelling and format variations. In such cases, it's necessary to use similarity functions instead of boolean operators. Query mechanisms that use similarity functions return a ranking of elements ordered by their score in relation to the query object. To define the relevant elements that must be returned in this ranking, a threshold value can be used. However, the definition of the appropriated threshold value is complex, because it depends on the similarity function used and the semantics of the queried data. One way to help to choose an appropriate threshold is to evaluate the quality of similarity functions results using different thresholds values on a database sample. This work presents an automatic method to estimate the quality of similarity functions through recall and precision measures computed for different thresholds. The results obtained by this method can be used as metadata and, through the requirements of an specific application, assist in setting the appropriated threshold value. This process uses clustering methods and cluster validity measures to eliminate human intervention during the process of estimating recall and precision.

Vocabulary acquisition plays an important role in second language students’ performance. In the process of learning vocabulary, students are exposed to different sorts of input that might affect the way their working memory processes, retains, and recalls the new information they are exposed to, which can be visual, auditory, haptic, or multimodal (Paivio, 1991). Research has been extensively done on the effects of input modality on working memory in L1 word recall tasks in individuals with normal development and also in individuals with visual disabilities; however, no attention has been given to the effects of input modality on working memory in word recall tasks in blind individuals in the realm of second language learning. The current research sought to investigate the effects of input modality on working memory in L2 word recall tasks with the goal of determining if the lack of access to visual stimuli would have any substantial effects on L2 word retention and recall. It was predicted that participants would do better on those word recall tasks that involved the use of more than one modality simultaneously and that lack of access to visual stimuli would not negatively affect L2 word recall. To address these issues, we devised two word recall experiments: experiment 1 for the blind participant of the study (a 24 year old female graduate student who is an English native speaker), and experiment 2 for the sighted participants. Both experiments comprised a Digit Span Test, 4 word recall tasks in which participants were exposed to four different lists of high frequency Spanish words and their English translations in different modalities (Oral, Written (Braille), Oral+Written (Braille), Haptic/visual+Oral), and an interview. Thirty (16 females, 14 males) American English Native speakers who were sighted with ages ranging from 19 to 37 participated in this study; half of them were blindfolded for the last word recall task (Haptic+Oral). The results for both experiments showed that contrary to our predictions and to what dual coding theories claim, our participants were able to recall more words in those tasks that involved the use of only one modality. In part this may be attributed to 1) the fact that it was the first time these participants were exposed to Spanish vocabulary and so it made it more difficult for their working memories to integrate modalities and 2) an information overload since the stimulus words were presented with their translation. Moreover, the lack of access to visual stimuli did not have a strong effect in those participants who were blindfolded, which may be explained by the fact that the oral and haptic input triggered the use of mental imagery when retaining and recalling the words. Finally, the practical and pedagogical implications of the findings of the present study, as well as recommendations for the future research are discussed.

Este estudo busca a abordagem de Tempo, Vida, Poesia, obra pouco estudada de Carlos Drummond de Andrade, publicada em 1986, produto final de uma série de oito entrevistas radiofônicas concedidas à amiga e jornalista Lya Cavalcanti, veiculadas, todos os domingos, pela PRA-2, Rádio Ministério da Educação e Cultura, na década de 1950. Objetiva-se no contexto de Tempo, Vida, Poesia, apreciar o trabalho literário da narrativa enquanto media fundamental da recordação que se projeta sobre a memória dos vestígios autobiográficos do autor. Neste sentido, a performance singular do prosador em foco permite identificar o percurso de uma vida literária, principalmente na empatia que estabelece com o receptor e a matéria da recordação e memória constituídas em imagens, que figuram sua própria complexidade subjetiva enquanto personagem. A riqueza poética do artifício de escrita encena a oralidade de uma experiência singular do narrador, possibilitando uma compreensão ampliada do fazer literário em foco / This study aims to approach Tempo, Vida, Poesia, a little studied work of Carlos Drummond de Andrade, published in 1986. This narrative is the final product from eight radio interviews, by Drummond depositions granted to journalist Lya Cavalcanti, and carried whit the PRA-2 - Radio Ministry of Education and Culture, in the 1950s. Objective in the context of Tempo, Vida, Poesia, appreciate the literary work of narrative as key to recall that project to the memory of autobiographical traces the author's 'media'. In this sense, the singular "performance" of the prose in focus allows us to identify the route of a literary life. Mainly on establishing empathy with the receiver and the matter of remembrance and memory incorporated in images contained its own subjective complexity as "character". The richness of poetic artifice with the written orality stages of a singular experience from the narrator, allowing an expanded understanding of literary writing in focus
