This article examines the long-term effects of divorce on adults whose parents divoiced during their childhood in Chile. A study of 35 adult Chileans found that many still fantasize about their parents 'reconciliation and as children had not been told about the divorce until one of the parents had already left the home. Preventive intervention oriented toward preparing both parents and their children for the impending divorce are suggested. 相似文献

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. 相似文献

Building enforcement capacity, that is, attaining and sustaining control in order to implement changes, is crucial for the success of public management reforms. However, this aspect of public management reform does not receive much theoretical or empirical attention. This paper analyzes the process of building enforcement capacity for the case of the Mexican Professional Civil Service reform. Although this reform experienced several complications (e.g., limited support, resources, and credibility), important goals were attained and some control was achieved. We study how officials attained control over implementation through the adaptive management of combinations of different types of control strategies (regulatory, normative, and procedural). The case study, focused on the analysis of in‐depth interviews with the highest officials involved in the implementation of this reform, finds evidence for three combinations of strategies next to a general pattern characterized by a trade‐off between compliance and coordination. This trade‐off shows that the process of building enforcement capacity may affect the goals of the reform, deviating from lawmakers' original intentions Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

In examining the failure of the 2002 peace process between the Sri Lankan government and the Liberation Tigers of Tamil Eelam (LTTE), this essay argues for the need to go beyond the power dynamics of the local actors. The peace process was dismantled and military victory by the Sri Lankan government made possible not so much by the Sinhala nationalist discourse, which opposed administration of development aid by the LTTE, as by the global security discourse associated with geo-strategic interests. The EU-led development discourse, which was informed by the liberal internationalist ethos, could have facilitated resolution and transformation of the conflict. In its place a security-based, realist discourse was prioritized in South Asia by the UK and US governments, particularly after the invasions of Afghanistan and Iraq. This was the discourse which provided the material basis for the Sinhala nationalists to consolidate their power in pursuing a military victory. The post-war era is marked by geopoliticization of the human rights discourse, deepening the conflict. This essay explores the correlation between the liberal peace model, human rights, international relations and geopolitics. 相似文献

The actual impact of economic growth on poverty reduction is of fundamental importance to the development agenda. This paper offers new empirical evidence on growth and poverty measured from a multidimensional perspective using the global Multidimensional Poverty Index. Results from a First Difference Estimator Model suggest that while economic growth reduces multidimensional poverty, this impact is well below a one-to-one relationship and lower than the impact of growth on income poverty. Results from a cross-section model additionally suggest that countries with higher levels of exports, higher share of industry and services and higher control of corruption have lower multidimensional poverty. 相似文献

In the last 20 years, the risks of bribing foreign public officials have greatly increased for multinational companies based in OECD countries and those listed on their stock markets. Generally, these risks can be mitigated through corporate compliance programs. Such compliance programs are directed at reducing bribery and other unethical behavior in the private sector. This paper assesses how the international standard against transnational bribery has impacted anticorruption compliance programs in Argentina. It first traces the origins and logics behind corporate anticorruption compliance. It later describes the international standard against transnational bribery and, in the light of information collected through 16 in-depth interviews and a survey conducted among 70 companies based in Argentina, it assesses how corporate anticorruption programs work in this country. After distinguishing between “paper”, “cheap-talk” ideal-type programs and sound, truly committed ideal-type policies, it suggests that anticorruption compliance in Argentina is placed closer to the former than the latter, and it offers possible reasons for such findings. 相似文献

This paper aims to evaluate the main intersectoral R&D flows in the Brazilian economy, determining their direction and magnitude. Unlike other studies that focus exclusively on rent spillovers flows of R&D, this paper also calculates spillovers with total spending on innovation in addition to R&D expenditure. In the case of developing countries, where R&D is of lower relative importance, we assume that technological effort is measured more accurately if it is considered as different types of innovative expenditure. We used data from the Technological Innovation Survey, conducted by the Brazilian Institute of Geography and Statistics with the support of Ministry of Science and Technology and data from an input–output matrix for the Brazilian economy, calibrated by Laboratório de Analises Territoriais e Setoriais—LATES of the Federal University of Juiz de Fora. The analysis is from the year 2011 and covers 32 sectors of economic activity resulting from the compatibility of the two databases. The main results show a mapping of the intersectoral flow of knowledge embodied both by the total expenditure on innovation and by in-house R&D to Brazil for the year 2011. It is important to highlight the wealth of detail of such a mapping, as it characterizes not only by sectoral interdependence of these aspects, but it also shows the direction of flows, the sectoral hierarchy in terms of “donation” of technical knowledge and the intersectoral flows in terms of technological intensity. 相似文献
