Does Dosage in Abstinence Education Matter? Será que a Dosagem na Educação para a Abstinência faz a Diferença?

Abstract Although past reviews uniformly criticized the efficacy and effectiveness of sexual abstinence in adolescents, new studies dispute the earlier findings. Studies that unpackage intervention programs provide one means of understanding why they succeed in some settings and not in others. This study examined 3183 students spread over 35 schools on the number of hours that they received in sexual abstinence education, in a context of health behaviors promotion. A multi-level analysis (HLM) was performed. The number of hours did not appear to make any difference in the outcome scores. Reasons for this finding are presented and their implications are provided. Keywords: sexual abstinence education, effectiveness, HLM, dosagem Resumo Embora a literatura duma forma generalizada tenha uniformemente criticado a eficácia dos programas de abstinência sexual em adolescentes, novos estudos parecem contestar os resultados iniciais. Estudos que descompactam os programas de intervenção fornecem um meio de entender por que os programas de abstinência podem ter sucesso em alguns contextos e não em outros. Este estudo analisou 3.183 alunos distribuídos por 35 escolas sobre o número de horas que eles receberam em educação para a abstinência sexual, num contexto de promoção de comportamentos saudáveis. Foi realizada uma análise multi-level (HLM). O número de horas não pareceu fazer diferença nos resultados obtidos. As razões para esta conclusão são apresentados e suas implicações são fornecidas.

Overweight People Have Low Levels of Implicit Weight Bias, but Overweight Nations Have High Levels of Implicit Weight Bias

Although a greater degree of personal obesity is associated with weaker negativity toward overweight people on both explicit (i.e., self-report) and implicit (i.e., indirect behavioral) measures, overweight people still prefer thin people on average. We investigated whether the national and cultural context - particularly the national prevalence of obesity predicts attitudes toward overweight people independent of personal identity and weight status. Data were collected from a total sample of 338,121 citizens from 71 nations in 22 different languages on the Project Implicit website (https://implicit.harvard.edu/) between May 2006 and October 2010. We investigated the relationship of the explicit and implicit weight bias with the obesity both at the individual (i.e., across individuals) and national (i.e., across nations) level. Explicit weight bias was assessed with self-reported preference between overweight and thin people; implicit weight bias was measured with the Implicit Association Test (IAT). The national estimates of explicit and implicit weight bias were obtained by averaging the individual scores for each nation. Obesity at the individual level was defined as Body Mass Index (BMI) scores, whereas obesity at the national level was defined as three national weight indicators (national BMI, national percentage of overweight and underweight people) obtained from publicly available databases. Across individuals, greater degree of obesity was associated with weaker implicit negativity toward overweight people compared to thin people. Across nations, in contrast, a greater degree of national obesity was associated with stronger implicit negativity toward overweight people compared to thin people. This result indicates a different relationship between obesity and implicit weight bias at the individual and national levels

Coherent Fourier scatterometry reveals nerve fiber crossings in the brain

Previous simulation studies by Menzel et al. [Phys. Rev. X 10, 021002 (2020)] have shown that scattering patterns of light transmitted through artificial nerve fiber constellations contain valuable information about the tissue substructure such as the individual fiber orientations in regions with crossing nerve fibers. Here, we present a method that measures these scattering patterns in monkey and human brain tissue using coherent Fourier scatterometry with normally incident light. By transmitting a non-focused laser beam (λ = 633 nm) through unstained histological brain sections, we measure the scattering patterns for small tissue regions (with diameters of 0.1-1 mm), and show that they are in accordance with the simulated scattering patterns. We reveal the individual fiber orientations for up to three crossing nerve fiber bundles, with crossing angles down to 25°.ImPhys/Optic

Psychologists role in Brazilian aviation - present and perspectives

This article describes a Group Discussion ocurred on the I National Congress of the Brazilian Aviation Psychology Association (ABRAPAV), in 2016. Among 158 participants on the event, 146 took part of this Group Discussion: 75 psychologists; 6 Psychology students; 25 other aviation profissionals; 40 professionals with unidentified formation. They chose one of the following subgroups to discuss about Aviation Psychology activities, facilities, difficulties and suggestions: Regular Aviation; Nonregular/ General Aviation; Military Aviation; Regulator Authority/Aeronautical Industry; Clinics/Hospitals; Airclubs/ Aviation Schools/ Universities/Training Centers; Air Navigation/Airports. After the discussion, each subgroup representative presented the results of the main activities, facilities, difficulties and suggestions, respectively, as examples: Aeronautical Accidents Prevention; Managers Recognition, Support and Confidence; Reactive Organizational Cultures, Changes Resistence and Inflexible Manager; Professional Specialization and Specific Standard for Aviation Psychology. This enabled ABRAPAV to map relevant demands in this area and plan strategies for psychologists to minimize constraints and support improvements in their organizations

Electric flight scheduling with battery-charging and battery-swapping opportunities

With the current advances in aircraft design and Lithium-Ion batteries, electric aircraft are expected to serve as a replacement for conventional, short-range aircraft. This paper addresses the main operational challenges for short-range flights operated with electric aircraft: determining the investment needs for a fleet of electric aircraft, and the logistics of charging stations and swap batteries required to support these flights. A mixed-integer linear program with two phases is proposed. In the first phase, a schedule for flight and battery recharge is developed for a fleet of electric aircraft. In the second phase, optimal times for battery charging are determined, together with an optimal sizing of the number of charging stations and swap batteries. We illustrate our model for short-range flights to and from an European airport and for an electric aircraft designed based on the operational characteristics of a conventional, narrow-body aircraft.Aerospace Transport & OperationsFlight Performance and Propulsio

World heritage mapping in a standard-based structured geographical information system

This research aims at the study of the (dynamic) relationship between the World Heritage sites and the related human settlements development. Geographical Information Systems (GIS) can be useful to represent the involved information and to analyze such relationship. However, an effective harmonized structure and unique storage of possibly heterogeneous datasets is necessary to enable it. This initial step is the focus of this paper. First, the description of the structure of the related datasets and the assessment of the availability, quality, and consistency of the available information about the Heritage sites and properties is presented. Among those requirements, the quality of the associated spatial information is critical (e.g. kind of shape, accuracy, georeferencing). Second, considering the structure of the available datasets concerning the world heritage, together with the HERILAND research requirements, a global world heritage GIS is designed. The classification and data model to manage the WH list falls within the wider issue of structuring the cultural heritage documentation, involving both the definition of the semantic content and the geometric representation. In order to comply with the important requirement of data interoperability in science and to strengthen the outcomes of the research, some standardized data models and classifications are considered.

Devising ecodesign strategies in a furniture industry based on cluster analysis

This study aims to devise group guidelines to implement ecodesign practices (Design for Environment) in the furniture industry. Surveys were the main research method used to investigate the level of application of ecodesign in 22 companies in southern Brazil. The term ecodesign was unfolded into ecodesign practices (set of activities), which were further developed into assessment items which were each assigned a question with categorical answers. The practices investigated are defined as follows: environmental management; (ii) materials (selection and choice); (iii) product components; (iv) process/product characteristics; (v) use of natural resources; (vi) product and stock distribution; (vii) packaging and documentation; and (viii) waste. A cluster analysis was made of the responses to the surveys through the k-means method and the four-cluster hypothesis. The cluster which most often applies ecodesign practices is comprised of enterprises with a previously structured environmental management system. In this case, the main guidelines suggest applying product Life Cycle Assessment, structuring environmental performance indicators and strengthening the image of the environmentally correct company. The main guidelines for the cluster which less often applies ecodesign practices refer to compliance with environmental laws and improvement of productive operations. The other two clusters partially adopt ecodesign practices

Dataset on the literature on public participation and consensus building: Bibliography and meta-analysis of selected studies

The data presented in this Data in Brief article offers an insight into the scientific literature on conceptual and empirical approaches to public participation and consensus-building. It consists of articles retrieved from the Scopus search engine which feature “public participation”, “consensus”, and “value and attribute” in the title, abstract, and author keywords. Information on the bibliography is recorded, namely title, author(s), year of publication, and source title. Metadata on how the articles were analyzed is provided in the dataset. From 121 publications, most literature (103) analyzes public participation through case studies. The studies were analyzed according to factors that were identified inductively and grouped in two categories: 1) public participation: actor, method, and level of public participation, and 2) consensus: approaches, conflict. The data is related to the research article entitled “Public participation and consensus-building in urban planning from the lens of heritage planning: A systematic literature review”. This paper focuses on the public participation factors as the factors on consensus are already explained in the main article. This paper shows which factors of participation were implemented in the analyzed studies. Given that, this article contributes to researchers and practitioners working on public participation because it reveals the diversity of approaches for consensus-building in public participation processes, which help them realize which level of participation they want to achieve and the means to reach it.Heritage & Architectur

Capturing public voices: The role of social media in heritage management

Social media platforms have been increasingly used by locals and tourists to express their opinions about buildings, cities, and built heritage in particular. Most recently, scholars have been using social media to conduct innovative research on built heritage and heritage management. Still, the application of artificial intelligence (AI) methods to analyze social media data for heritage management is seldom explored. This paper investigates the potentials of short texts (sentences and hashtags) shared through social media as a data source and artificial intelligence methods for data analysis for revealing the cultural significance (values and attributes) of built heritage. The city of Yazd, Iran was taken as a case study, with the particular focus on windcatchers, key attributes conveying outstanding universal values, as inscribed on the UNESCO World Heritage List. This paper has three subsequent phases: 1) state of the art on the intersection of public participation in heritage management and social media research; 2) methodology of data collection and data analysis related to coding people's voices from Instagram and Twitter into values of windcatchers over the last ten-years; 3) preliminary findings on the comparison between opinions of locals and tourists, sentiment analysis, and its association with the values and attributes of windcatchers. Results indicate that the age value is recognized as the most important value by all interest groups, while the political value is the least acknowledged. Besides, the negative sentiments are scarcely reflected (e.g., critiques) in social media. Results confirm the potential of social media for heritage management in terms of (de)coding and measuring the cultural significance of built heritage for windcatchers and also other attributes in Yazd and other case studies and scales.Heritage & Architectur
