Counting Portuguese colonial populations, 1776–1875: a research note

In 1776 the Portuguese Crown decreed that statistical population tables were to be compiled in all its overseas possessions. Using a defined model, each governor was to send annually a population count for the area under his jurisdiction. In the Arquivo Histórico Ultramarino (AHU) in Lisbon there are over a thousand statistical population tables from Brazil to Macau. This documentary corpus opens up important horizons for demographic, social and colonial history, though it has been relatively ignored by historians and demographers. These sources enable us to study the demography and the administrative processes adopted in census-taking during the construction of the Portuguese Empire between 1776 and 1875. The following research note emphasizes the distinctive aspects of the sources, the data and its potential, and the research agenda.     

The enhanced cognitive interview: expressions of uncertainty,motivation and its relation with report accuracy

The Enhanced Cognitive Interview (ECI) is one of the most widely studied and used methods to interview witnesses. However, ECI research has mainly focused on increasing report size and somewhat overlooked how to improve and evaluate report accuracy. No study evaluated if witnesses’ spontaneous expressions of uncertainty are accurate metacognitive judgments, nor if witnesses’ motivation during the interview affects report accuracy. This study examined how witnesses’ judgments of recall ‘uncertainty’ and their motivation perception could relate to report accuracy. Forty-four psychology students watched a mock robbery video recording and were interviewed 48 hours later with either the Portuguese version of the ECI or a Structured Interview (SI). Afterward, participants’ motivation was assessed and items of information were classified as ‘certainties’ or ‘uncertainties’. Results suggest that our ECI protocol was effective, since participants interviewed with the ECI produced more information without compromising accuracy. ‘Uncertainties’ were less accurate than ‘certainties’, and their exclusion raised overall, ECI, and SI, accuracy. More motivated participants had better recall accuracy. Accounting for witnesses’ motivation and spontaneous verbal expressions of uncertainty may be effective and time-saving procedures to increase accuracy. These are key points that professionals and researchers should consider.     

Deep learning for sex determination: Analyzing over 200,000 panoramic radiographs

The objective of this study is to assess the performance of an innovative AI-powered tool for sex determination using panoramic radiographs (PR) and to explore factors affecting the performance of the convolutional neural network (CNN). The study involved 207,946 panoramic dental X-rays and their corresponding reports from 15 clinical centers in São Paulo, Brazil. The PRs were acquired with four different devices, and 58% of the patients were female. Data preprocessing included anonymizing the exams, extracting pertinent information from the reports, such as sex, age, type of dentition, and number of missing teeth, and organizing the data into a PostgreSQL database. Two neural network architectures, a standard CNN and a ResNet, were utilized for sex classification, with both undergoing hyperparameter tuning and cross-validation to ensure optimal performance. The CNN model achieved 95.02% accuracy in sex estimation, with image resolution being a significant influencing factor. The ResNet model attained over 86% accuracy in subjects older than 6 years and over 96% in those over 16 years. The algorithm performed better on female images, and the area under the curve (AUC) exceeded 96% for most age groups, except the youngest. Accuracy values were also assessed for different dentition types (deciduous, mixed, and permanent) and missing teeth. This study demonstrates the effectiveness of an AI-driven tool for sex determination using PR and emphasizes the role of image resolution, age, and sex in determining the algorithm's performance.     

Towards Performance,Quality and Environmental Management in Local Government: the Case of Spain

The search for improvements in the management and quality of public services seems to be a constant in all public administrations, and there is an ever-increasing use of management techniques and models from the business sector. The aim of this paper is to show which management systems are being used by Spanish local governments to improve their management in terms of economy, quality and the environment. Our analysis is based on a questionnaire sent to Spanish local governments about the tools they use and the factors that influence their implementation. The results show that more efforts are necessary to implement performance measurement and total quality management, but they also show some positive aspects, such as the usefulness of performance measurement and its application to decisions in those local governments that have implemented it.     

Openness and Growth: Re-Examining Foreign Direct Investment,Trade and Output Linkages in Latin America

The openness–growth connection is still an open question in the empirical literature. Although some studies have found that openness has a positive impact on economic performance, others have seriously questioned the significance of this result. The main point that we try to emphasise in this paper is that openness involves more than just trade liberalisation. The increasing importance of international capital flows and especially foreign direct investment (FDI) seems to be another relevant component of outward oriented policies. Therefore, by using quarterly data from the late seventies to 2000, we investigate the effects of liberalisation in Mexico, Brazil and Argentina by taking into account trade and FDI growth links. The results suggest that it is important to consider both exports and FDI to ascertain the benefits associated to the outward oriented strategies followed by these countries.     

Identification of a Carbonized Body Using Implanted Surgical Plates: The Importance of Computed Tomography

In addition to clinical examination, forensic odontologists can use diagnostic imaging as an auxiliary method for identification. This paper reports a case where forensic odontologists from the Afrânio Peixoto Legal Medicine Institute in Rio de Janeiro (Brazil) positively identified a carbonized and partially calcined body using oral and maxillofacial imaging. The cadaver showed several metallic plates fixed with metallic screws on bones of the neurocranium and viscerocranium. Family members provided spiral computed tomography scans of the skull and a panoramic radiograph that were acquired after an accident that required surgical procedures. Comparative analysis between the clinical exam and the maxillofacial images demonstrated complete coincidence, confirming the victim's identity. Dactyloscopy, which is the most commonly used method of identification, was not possible because of the body carbonization. Thus, diagnostic imaging, especially computed tomography, was essential for elucidation of this case.     

Enhancing the cognitive interview with an alternative procedure to witness-compatible questioning: category clustering recall

The Cognitive Interview (CI) is one of the most widely studied and used methods to interview witnesses. However, new component techniques for further increasing correct recall are still crucial. We focused on how a new and simpler interview strategy, Category Clustering Recall (CCR), could increase recall in comparison with witness-compatible questioning and tested if a Revised Cognitive Interview (RCI) with CCR instead of witness-compatible questioning and without the change order and change perspective mnemonics would be effective for this purpose. Participants watched a mock robbery video and were interviewed 48 hours later with either the CI or the RCI. Recalled information was classified as either correct, incorrect or confabulation. Although exclusion of the change order and change perspective mnemonics in the RCI group might have caused a slight decrease in recall during the last interview phases, the RCI group generally produced more correct information than the CI group, with a lower number of confabulations. Further analyses revealed CCR was largely responsible for this increase in correct recall. CCR is a very promising interview technique which allowed the interviewer to obtain more detailed information without additional questions and may have, in certain situations, several practical advantages over a questioning phase.
