Risk management requires the use of a number of mathematical models for calculation. To use these models, it is necessary to form large databases on the quantitative characteristics of both the studied objects/processes/systems and the surrounding environment and conditions of the task. Implementation of this program requires the use of modern information technologies. The article analyzes the methodology for the formation of quantitative risk values, which allows for the formation of approaches to a certain standard for performing risk analysis for complex situations. A system of mathematical models and methods is proposed that allow building a system of quantitative modeling of risk situations for a wide class of objects/processes/systems. The article provides a comparative analysis of deterministic and stochastic risk management models, analyzes the riskiness model of risk stratification and the model for detecting differences from white noise. For the latter, a comparison of the experimental and theoretical concepts of the models was made. Information technologies that help organizations effectively identify, analyze and manage various types of risks, while providing a reliable protection mechanism against possible threats, such as ERM Systems, GRC Platforms, IRM Solutions, Cybersecurity Risk Management, Project Risk Management and Data Risk, are highlighted and analyzed Management.

The luxury consumer market in my country is developing rapidly. However, due to the differences in the culture and consumer psychology of different regions in my country, the marketing status of luxury goods in my country will be different in different regions. Under the premise of analyzing consumer groups, it deeply analyzes the factors that affect the luxury consumption psychology of Chinese consumers, expounds this psychological state, and then analyzes the problems existing in my country’s luxury goods marketing. Finally, based on consumer psychology, suggestions on luxury marketing related to these issues have been put forward. In addition, quantitative research on marketing and how to psychologically open a new chapter of marketing in the luxury goods industry have always been the core themes that foreign marketing researchers will continue to explore for a long time. The logo model is an excellent analysis in this process. By introducing the principles of the logo model and applying this model to the empirical study of domestic consumers’ choice of a specific luxury brand, it is shown that the logo model can be used to analyze many problems in marketing research. More useful quantitative information is undoubtedly of great benefit to the academic research of marketing and the practice of marketing management.

When a major accident occurs in a chemical industry park, it directly affects the personal safety of operators and neighboring residents and causes major losses; therefore, we should take measures to strengthen the management of chemical industry parks. This article proposes and analyzes a new dynamic semi-quantitative risk calculation model for chemical plants that can be applied digitally. This model provides a sustainable, standardized, and comprehensive management strategy for the safety management of chemical plants and chemical industry park managers. The model and its determined parameters were applied to the safety management of chemical companies within the chemical industry park of Quzhou, Zhejiang Province. From the point of view of the existing semi-quantitative model, the existing problems of the current model are analyzed, the current model is optimized, and a new dynamic semi-quantitative calculation model scheme is proposed. The new model uses an analytical hierarchy process targeting the factors affecting the risks in chemical plants, and chemical plant semi-quantitative dynamic calculation system consisting of the operator, process/equipment, risk, building environment, safety management, and domino effect, and the comprehensive risk of the chemical plant was calculated. The model is ultimately a real-time quantitative value, but its calculation process can compare and analyze the causes of high risk in a chemical plant as they relate to these six factors. Its implementation requires only software, which will greatly help chemical plant safety management.

Although unsustainable natural resource consumption has recently garnered significant attention in macrosociology, empirical studies neglect to analyze the environmental impacts of different forms of international power dynamics. This study dissects international power into its various economic, military, and export dependence characteristics, and analyzes their independent effects on per-capita consumption of natural resources, measured as ecological footprints. Findings of the quantitative cross-national analyses indicate that economic power in the form of capital intensity, military technological power, and overall export dependence are the structural driving forces of per-capita resource consumption. The effects of military technological power and export dependence on percapita footprints are primarily direct, whereas the effect of capital intensity is both direct and indirect, partly mediated by its effects on levels of secondary education and domestic income inequality, both of which impact levels of per-capita consumption. The results advance our collective understanding of the complexities of international power, domestic conditions, and uneven environmental outcomes and illustrate the necessity for taking a more nuanced approach to analyses of anthropogenic degradation of the global ecological system.

The US economy is facing instability due to high inflation and high credit card debt. Central banks have adopted quantitative easing (QE) as a monetary policy tool to promote economic growth and reduce the risk of deflation. QE measures originated from the 2008 global financial crisis to counter the threat of recession and deflation. This paper examines the impact of quantitative easing on the U.S. economy in four stages through data, image analysis and collection of related literature. Quantitative easing is a high-risk monetary policy. However, while quantitative easing stimulates the economy by lowering interest rates, it can also lead to inflation and borrowing pressures. This paper applies a combination of qualitative analysis and quantitative analysis, has been about the theory of monetary policy on the basis of the process of successive QE is summarized, and the Federal Reserve's aggressive interest rate hikes in the past two years to review. Finally, this paper analyzes the impact of QE, an unconventional monetary policy on the economy, and analyzes the future forecast. The research in this paper can be a certain reference for the monetary policy to cope with the crisis and unconventional situations.

Texto completoResumen
This research analyzes the impact on land use induced by urban solid waste landfills using the Weighted Environmental Index (WEI). The methodology used to analyze the environmental value of the landfill’s areas of influence is based on the analysis of the space-time variations of the WEI inside them. The application of this methodology allows identifying the areas where the environmental value has changed over time, providing a quantitative indicator that can be analyzed using statistical techniques. The methodology has been applied as a case study to analyze the influence over land use in all the municipal solid waste landfills currently in operation inside the Valencia Region (Spain). Results have been obtained using GIS techniques integrating the information provided by the Information System on Land Occupation in Spain land use database. Results show that, without exception, the environmental value of the territory has decreased in all the cases analyzed. WEI is a powerful tool for analyzing land use change over time, and its application allows for performing detailed statistical analyses leading to key conclusions about land use changes inside the landfill influence areas.

Texto completoResumen
Les plantes sont utilisées depuis des millénaires pour les traitements médicinaux. Cannabis sativa L. est une plante très controversée, classée comme stupéfiants dans la majorité des pays. Les phytocannabinoïdes, métabolites secondaires sécrétés dans ses trichomes, ont la capacité de se fixer sur les récepteurs CB1 et CB2 du système endocannabinoïde de l’homme. Ce système participe à la régulation de multiples fonctions physiologiques de notre organisme, tels que la régulation de la douleur, de l’appétit etc. Le tétrahydrocannabinol (THC) ou cannabidiol (CBD) admettent donc des potentiels thérapeutiques en concentrations contrôlées. Ces travaux de thèse s’inscrivent au sein de l’expérimentation du cannabis thérapeutique sous l’égide de l’ANSM en France. Dans une première partie, l’ensemble des expériences ont été préparées sur une plante modèle, Humulus lupulus L. appartenant également au cannabacées. Dans une seconde partie, une variété « THC dominant » de Cannabis sativa L. a été soumise à de multiples méthodes extractives (SE, UAE, MAE, PLE) permettant l’étude des rendements massiques (≈25%). Des dosages colorimétriques ont établis les TPC, TFC, TCC, TCCa et le pouvoir antioxydants des extraits. Les molécules volatiles ont été étudiées par HS-SPME-GC-MS et les phytocannabinoïdes par quantifications et déréplication (GNPS et SIRIUS) en LC-MS/MS. Les séparations et purifications ont permis d’obtenir le THCA, Δ-9THC, Δ-8THC et le CBN, dont la structure moléculaire a été vérifiée par RMN 1D et 2D. Des études statistiques (Désirabilité globale, TOPSIS) et plan d’expérience (DSD) ont permis d’établir les meilleures extractions en fonction de l’ensemble des résultats précédents. Enfin, des essais de formulation conformes à la Pharmacopée Européenne ont été réalisés proposant des comprimés sublinguaux de CBDPlants have been used for medicinal treatments for thousands of years. Cannabis sativa L. is a controversial plant, classified as a narcotic in most countries. Phytocannabinoids, secondary metabolites secreted in trichomes, have the ability to bind to CB1 and CB2 receptors in the human endocannabinoid system. This system is involved in regulating many of our body's physiological functions, such as pain and appetite. Tetrahydrocannabinol (THC) and cannabidiol (CBD) therefore have therapeutic potential in controlled concentrations. This thesis work is part of the experimentation with therapeutic cannabis under the aegis of the ANSM in France. In the first part, all the experiments were carried out on a model plant, Humulus lupulus L., also belonging to the Cannabaceae. In the second part, a 'THC dominant' variety of Cannabis sativa L. was subjected to multiple extractive methods (SE, UAE, MAE, PLE) to study mass yields (≈25%). Colorimetric assays established the TPC, TFC, TCC, TCCa and antioxidant power of the extracts. Volatile molecules were studied by HS-SPME-GC-MS and phytocannabinoids by quantification and dereplication (GNPS and SIRIUS) in LC-MS/MS. Separations and purifications yielded THCA, Δ-9THC, Δ-8THC and CBN, whose molecular structure were verified by 1D and 2D NMR. Statistical studies (Global Desirability, TOPSIS) and experimental design (DSD) were used to establish the best extractions based on all the previous results. Lastly, formulation tests in compliance with the European Pharmacopoeia were carried out on CBD sublingual tablets

Resumo: Dois métodos de cocção (forno e chapa) e três temperaturas internas finais (65, 71 e 77°C) foram aplicados em contrafilé bovino (m. longissimus lumborum), com o objetivo de avaliar qual dos procedimentos proporciona a obtenção de um produto com perfil sensorial descritivo superior em relação à qualidade sensorial. As amostras de contrafilé, porção compreendida da 12º costela e a 2º vértebra lombar, de meias carcaças esquerdas de bovinos da raça Angus, da mesma idade e acabamento de gordura, foram coletadas e congeladas (-20ºC). Cada peça foi cortada em seis bifes de 2.54 cm, que foram embalados a vácuo e mantidos congelados. Os bifes foram distribuídos em seis tratamentos. Para a cocção, os bifes foram descongelados a 4°C por 24 horas antes das análises. As temperaturas internas foram monitoradas por meio de termopares inseridos no centro geométrico de cada bife. Para a perda de peso por cocção, houve interação significativa do método de cocção X temperatura interna final (p=0.002). O aumento da temperatura aumentou constantemente as perdas por cocção em ambos os métodos de cocção, de 65ºC para 77ºC. A 65ºC e 71ºC as perdas por cocção foram similares entre forno e chapa, enquanto a 77ºC, as amostras assadas no forno tiveram as maiores perdas, provavelmente devido ao longo tempo de preparo. Para a força de cisalhamento, não houve interação do método de cocção X temperatura interna final (p=0.54). Os bifes preparados a 65°C e 71ºC tiveram menores valores de WBSF (p<0,05), enquanto que aqueles preparados a 77°C tiveram valores maiores (p<0,05). Na análise de aceitação, a aparência, o aroma e o sabor tiveram maior aceitação nas amostras preparadas no forno elétrico em temperaturas mais altas, entretanto a maciez e a suculência tiveram maior aceitação nas amostras preparadas em temperaturas mais baixas, independente do método de cocção. Os bifes grelhados na chapa elétrica a 65°C foram melhores, porque proporcionaram a obtenção de uma amostra com aceitação significativamente superior em relação a todas as características sensoriais analisadas. Na Análise Descritiva Quantitativa, os bifes do forno e da chapa a 65°C foram principalmente caracterizados pelos atributos de aroma e sabor de sangue, sabor metálico, suculência, maciez, suculência aparente e cor interna vermelha. Na análise tempo-intensidade, a Imáx do estímulo maciez e suculência foi significativamente maior (p<0,05) no forno elétrico em relação à chapa elétrica. E em relação às temperaturas a Imáx das amostras submetidas a 65 e 71ºC não diferiram (p>0,05), mas diferiram (p<0,05) das amostras a 77ºC. O Ttot não foi diferente (p>0,05) para as amostras nos métodos de cocção e nas temperaturas internas finais para os estímulos de maciez e suculência. Portanto sugere-se que as diferenças encontradas pelos assessores na maciez e suculência das amostras, foram percebidas somente a primeira mordida (Imáx). E durante a mastigação até a fase de deglutição (Ttot) não variaram, indicando que as amostras permaneceram igualmente homogêneas em relação aos dois atributos após a primeira mordida
Abstract: Two cooking methods (oven and griddles) and three end-point temperatures (65, 71 and 77°C) were applied in beef strip loin (m. longissimus lumborum), to assess which of the procedures provides a product with superior descriptive sensory profile in order to the sensory quality. Strip loin samples with the similar degree of fat thickness from the 12th rib to the second lumbar vertebra of the left side of the carcass of similarly age Angus steers were collected and frozen (-20ºC). Each piece was cut into six 2.54 cm thick steaks. The steaks remained vacuum packed and frozen. For cooking, the steaks were thawed at 4°C for 24 hours. The internal temperatures were monitored by thermocouples inserted in the geometric center of each steak. The interaction between cooking method and end-point temperature had a significant (P=0.002) impact on cooking loss. The increasing end-point temperature, constantly increase levels of cooking loss in both cooking methods, from 65ºC to 77ºC. At 65ºC and 71ºC the cooking loss were similar between oven and griddle, while at 77ºC the oven had the great loss, probably due to the long cooking. The interaction between cooking method and end-point temperature did not significantly impact (P=0.54) shear force. The steaks prepared at 65°C and 71ºC had lower (P<0.05) shear force values, while those prepared at 77°C had higher values (P<0.05). In acceptance analysis of appearance, aroma and flavor, samples cooked in electric oven, at higher temperatures, had the greater acceptance, however the tenderness and juiciness had greater acceptance in samples prepared at lower temperatures, regardless the method of cooking. Steaks grilled on the counter-top griddles at 65°C yielded a sample with a significantly greater acceptability in terms of all of the sensory characteristics analyzed. For Descriptive Quantitative Analysis, steaks prepared in oven and griddles at 65°C were mainly characterized by a blood aroma and flavor, a metallic flavor, juiciness, initial tenderness, apparent juiciness and internal red color. In the time-intensity analysis, the Imax values for tenderness and juiciness stimuli was higher (P<0.05) for the samples subjected to the electric oven as compared to the electric griddles. Regarding the temperatures, although the Imax for tenderness and juiciness of the samples subjected to temperatures of 65 and 71ºC were not different (P>0.05), it differed (P<0.05) from the samples at 77ºC. The Ttot value was not different (P>0.05) for both cooking methods and end-point temperatures in relation to the stimuli tenderness and juiciness. It can be suggested that the differences on tenderness and juiciness found by the assessors were noted only at first bite (Imax). Perception of tenderness and juiciness during chewing to swallowing (Ttot) did not vary, indicating that the samples remained homogeneous for both attributes after the first bite

Resumo: O café é um produto agrícola cujo preço está baseado em parâmetros qualitativos. O Brasil é o maior produtor e exportador, apresentando a possibilidade de produzir vários tipos diferentes de café, ampliando capacidade de atender as diferentes exigências mundiais do mercado. A incidência de fungos durante a secagem deprecia a bebida. Este trabalho teve como objetivo a procura de tratamentos que prevenissem ou paralisassem a contaminação fúngica através da utilização de cloreto de benzalcônio e dióxido de enxofre. Os ensaios realizados em pré e/ou pós-colheita variaram o tipo do fungistático, a dosagem aplicada e o número de aplicações realizadas. Foram realizadas as determinações: umidade, atividade de água, pH, acidez total titulável, ácidos clorogênicos, contagem de bolores e leveduras, identificação da microbiota fúngica, determinação de ocratoxina, "prova da xícara" e análise descritiva quantitativa dos cafés. Os resultados mostraram que houve diferenciação dos cafés submetidos aos tratamentos. Foram identificados diversos gêneros de fungos durante a secagem: Aspergillus spp., Cladosporíum sp, Colletotrichum sp, Fusarium sp, Leveduras, Penicilium sp e outros. Na testemunha e no tratamento de menor dosagem de fungistático houve crescimento de Aspergillus ochraceus. Os cafés submetidos aos tratamentos com dióxido de enxofre e maior número de aplicações indicaram tendência a melhorar a bebida, na "prova da xícara" os cafés obtidos receberam classificação de "dura a estritamente mole". Na análise descritiva quantitativa (ADQ) os cafés foram separados na análise de componentes principais indicando que houve efeito dos tratamentos na diferenciação da bebida

Resumo: O mercado de alimentos e bebidas prontos para o consumo está em expansão. Porém, os consumidores querem desfrutar de produtos que não apenas saciem a fome e a sede, mas que ofereçam vantagens nutricionais, segurança e qualidade sensorial. Os consumidores estão conscientes da importância de dietas e estilo de vida saudáveis. Alimentos com reduzido teor ou isentos de gorduras e açúcares auxiliam na adequação da dieta e na promoção da saúde. Os leites fermentados, por exemplo, o iogurte, vêm recebendo especial atenção pelas indústrias de alimentos e estão sendo muito procurados pelos consumidores de todas as idades, gêneros e classes sócio-econômicas, pois são nutritivos, práticos e de rápido consumo, além de poderem ser excelentes veículos de probióticos, tornando-os alimentos funcionais. Isso justifica o presente trabalho que teve por principal objetivo adoçar iogurte natural desnatado batido com edulcorantes na concentração equivalente à ideal de sacarose para que as fórmulas diet se apresentassem sensorialmente iguais ou similares à com sacarose. Determinou-se, primeiramente, a concentração ideal de sacarose pelo método de consumidor de doçura ideal utilizando-se da Escala-do-Ideal. Em seguida, determinou-se a equivalência em doçura do aspartame, sucralose, acessulfame-K, mistura sacarina/ciclamato (1:2), extrato de folha de estévia (Stevia 1) (53,7% esteviosídeo; 24,8% rebaudiosídeo A) e extrato de folha de estévia (Stevia 2) (15,3% esteviosídeo; 49,7% rebaudiosídeo A) pelo teste de Estimação de Magnitude com equipe treinada. As concentrações de sacarose, aspartame, sucralose, acessulfame K, mistura sacarina/ciclamato (1:2), Stevia 1 e Stevia 2 usadas, foram, respectivamente, em porcentagem (p/v): 9,7%, 0,0551%, 0,0223%, 0,0608%, 0,0520%, 0,1445% e 0,1588%. As amostras foram submetidas à Análise Descritiva Quantitativa (ADQ) para que fosse possível traçar seus perfis sensoriais. Utilizou-se painel de 10 julgadores treinados para os descritores de Aparência (Cor Branco-Amarelada, Viscosidade), Aroma (Aroma de Iogurte); Sabor (Doçura, Acidez, Amargor, Sabor de Iogurte, "Gosto de Remédio") e Textura (Homogeneidade, Cremosidade). Concluiu-se que os edulcorantes estudados conferiram perfil sensorial semelhante ao da sacarose no iogurte. Apenas os extratos de estévia conferiram amargor e "gosto de remédio" e reduziram a percepção de doçura e sabor de iogurte. Por fim, conduziu-se análise de aceitação por 120 consumidores do produto para aparência, aroma, sabor, textura e impressão global. Os consumidores também responderam questionário sobre consumo de iogurte e alimentos dietéticos e expressaram seu grau de aceitação pelas amostras em escalas hedônicas lineares não estruturadas de 9cm. Além disso, responderam à intenção de compra em escala de atitude de 5 categorias. Paralelamente à aceitação, realizou-se medidas instrumentais de cor, viscosidade, pH, acidez total titulável e sólidos totais, permitindo a comparação entre os dados sensoriais e instrumentais. Os resultados, de forma geral, indicaram que os extratos de estévia não são indicados para uso em iogurte natural desnatado batido e precisam ser melhorados para ter sucesso na substituição total da sacarose. A sucralose e o aspartame são os edulcorantes que mais se aproximaram do perfil sensorial da sacarose e foram igualmente aceitos pelos consumidores assim como a amostra com sacarose, sendo, portanto, os mais indicados para uso nesse produto. Os edulcorantes também não influenciaram as medidas físico-químicas do iogurte quando comparados com o iogurte puro e com sacarose (padrões). Pode-se dizer, portanto, que é possível a substituição da sacarose por edulcorantes intensos. Porém, os extratos de estévia devem ser reformulados e, provavelmente, usados em misturas de edulcorantes para que sua aplicação na indústria de alimentos seja bem sucedida
Abstract: The market of "ready to eat/drink" foods and beverages is expanding. However, consumers want to enjoy products that will not only satisfy their hunger and thirst but also offer nutritional advantage, safety and sensory quality. Nowadays, consumers are well aware of the importance of healthy eating habits and lifestyles. Foods with low content or even free of fats and sugar help people to adequate diet and promote good health. Fermented milks like yogurt have been receiving special attention by the food industries and have become more and more popular among consumers of all ages, genders and walks of life, as they are nutritional, practical and easy to consume, besides being excellent vehicles for probiotic microorganism, which makes yogurts functional foods. That all justifies this study the object of which was to sweeten natural skimmed shaken yogurt using different sweeteners in equivalence to the ideal concentration of sucrose in order that the diet formulas would taste as close to the original as possible. Firstly, ideal sweetness was determined by the Just-About-Right scale using 30 consumers of the product. Secondly, the equivalence in sweetness and the sweetening power in relation to sucrose was determined by Magnitude Estimation method using 12 judges. The ideal sweetness of sucrose to this yogurt was 9,7%. The sweetening power was equal to 176 (Aspartame), 67,1 (Stevia 1), 61,1 (Stevia 2), 435 (Sucralose), 186,5 (Saccharine/Cyclamate 1:2) and 159,5 (Acessulfame-K). The seven samples of yogurt obtained were submitted to Quantitative Descriptive Analysis (QDA) so that their sensory profile could be determined. A panel made up of 10 judges was trained for the descriptive terms of Appearance (Yellowish-white color, Viscosity), Aroma (Yogurt aroma), Flavor (Sweetness, Sourness, Bitterness, Yogurt flavor, Medicine taste) and Texture (Homogeneity, Creaminess).The results showed almost all sweetener gave yogurt sensory profile similar to sucrose. Only the Stevia extracts gave it a bitter and medicine-like taste and reduced the perception of sweetness and yogurt flavor. Finally, acceptance analysis was performed among 120 consumers of natural yogurt concerning Appearance, Aroma, Flavor, Texture and Overall Impression. Consumers were requested to answer a questionnaire about yogurt consumption and expressed their liking using a using non-structured linear hedonic scale of 9cm. Besides, they indicated their purchase intention of each sample by using a 5-point attitude scale. In addition to sensory analysis, physical-chemical measurements of pH, total acidity, total solids and viscosity were carried out, which enabled a comparison between the sensory and the instrumental data. The overall results showed that the Stevia extracts are not recommended for natural yogurt. They should be improved so that they can successfully replace sucrose. Sucralose and aspartame are the sweeteners that come closest to the sensory profile of sucrose and the ones that were accepted by consumers as well as sucrose. Therefore, they are the best choice for this kind of yogurt. Also these sweeteners did not influence physical-chemical measurements of the yogurt when compared to the same yogurt with or without sugar that is the standard. It is possible to say that the substitution of sucrose for intense sweeteners is viable and it fulfils nutritional and sensory consumer's needs

A presente dissertação teve como principal objetivo avaliar o nível de adequação das técnicas estatísticas de análise multivariada em dissertações e teses da área de Marketing, na temática do comportamento consumidor, entre 1997 e 2006, apresentadas aos Programas de Pós Graduação da Faculdade de Economia, Administração e Contabilidade da Universidade de São Paulo e da Escola de Administração de Universidade Federal do Rio Grande do Sul. Para atender a esse objetivo, buscou-se organizar um referencial teórico que subsidiasse a discussão sobre os objetivos de aplicação de cada uma das técnicas, bem como que subsidiasse a construção de um procedimento de avaliação a partir do atendimento a premissas subjacentes ao uso dessas técnicas. Foram analisados cinqüenta e seis estudos com aplicação das técnicas multivariadas, dentre os cento e noventa seis estudos disponíveis sobre a temática em referência no período. Desse universo, delimitou-se o público-alvo em noventa e nove aplicações dessas técnicas. A adequação da aplicação das técnicas às necessidades dos problemas de pesquisa foi verificada em 100% dos casos. Entretanto, quanto ao atendimento às premissas, o resultado foi negativo: apenas 16,8% das aplicações mostraram-se adequadas, atendendo a todas as premissas exigidas. A técnicas de Análise Fatorial Exploratória foi a mais utilizada no período, seguida da Modelagem de Equações Estruturais e da Análise de Regressão. As premissas mais verificadas foram a de sensibilidade ao tamanho da amostra e a de padronização dos dados; as menos verificadas foram as premissas de normalidade multivariada, linearidade, homoscedasticidade e autocorrelação dos resíduos. De forma geral, os resultados sugerem a necessidade de um aumento do comprometimento dos pesquisadores na verificação de todos os preceitos teóricos de aplicação de cada técnica.This dissertation has the purpose to evaluate the level of adaptation of the statistics technique of multivariate analysis in dissertations and theses related to Marketing, consumer behavior, during 1997 and 2006, introduced at Programs of Masters degree of the Faculdade de Economia, Administração e Contabilidade da Universidade de São Paulo and of the Escola de Administração da Universidade Federal do Rio Grande do Sul. To reach this purpose, was organized a theoretical referential that would subsidize the discussion about the objectives of each technique application, and one that would subsidize the construction of an evaluation procedure starting with the attention to the subjacent premises to the use of these techniques. It was analyzed fifty-six studies of a hundred-ninety-six available on the thematic on the period, which used multivariate application techniques. Based on a consumer target, was delimited ninety-nine applications of that technique. The application of the techniques was observed at 100% of the cases where they were suited to the necessities of the research problems. However, taking the premise attention the results were negative: only 16.8% of the applications were suited, following all the premises required. The technique Factorial Exploration Analysis was the most used technique on the period, followed by Structures Equations Modeling and Regression Analysis. The most verified premises were the sensibility to the size of the sample and the data standardization; the least verified were multivariate normality, linearity, homoscedasticity, and autocorrelation. The results suggest the necessity of a higher commitment of the researchers on the verification of all theoretical precept of each technique application.

Os escorregamentos são movimentos de massa recorrentes na Serra do Mar. Quando ocorrem de forma generalizada podem causar prejuízos e perdas de vidas, como no acidente ocorrido no município de Caraguatatuba (SP) em 1967. Com o intuito de evitar estes danos, na literatura, são propostos vários métodos para analisar e prever a ocorrência destes processos. Diante do exposto, o objetivo principal desta pesquisa consiste em analisar a suscetibilidade a escorregamentos na região entre Caraguatatuba e São Sebastião (SP), utilizando a compartimentação fisiográfica e a análise quantitativa. Para alcançar estes objetivos foi realizada a análise e compartimentação do terreno e a análise quantitativa dos fatores condicionantes (declividade, hipsometria e geologia) e da compartimentação fisiográfica. Foram testados, em ambiente SIG, diversos cenários a partir de dois métodos distintos. No Método 1, os fatores condicionantes foram analisados através de pesos de influência. No Método 2, os fatores condicionantes mantiveram os mesmos pesos do Método 1 e foram somados pesos para as classes de cada fator. A compartimentação fisiográfica definiu 16 unidades. Os resultados demonstraram que a maioria dos escorregamentos se concentraram na unidade fisiográfica IV e que há um controle topográfico na distribuição dos escorregamentos entre 100 e 400 m de altitude, em encostas com declividade entre 15º e 30º, compostas por gnaisse migmatítico e granito-gnaisse. Os mapas elaborados a partir do Método 2 apresentaram expressiva concordância com o mapeamento de cicatrizes de Fúlfaro et al. (1976). O cenário escolhido como mais coerente foi o Cenário O, em que houve 60% de influência da declividade, 30% de hipsometria e 10% de geologia. Portanto, a partir do estudo da suscetibilidade, por meio da análise fisiográfica e quantitativa, é possível afirmar que o fator que tem mais influência na ocorrência de escorregamentos, na área de estudo, é a declividade, seguida da hipsometria e geologia.
Landslides are recurrent mass movements in the Serra do Mar. When they occur in a generalized way, as in the event occurred in Caraguatatuba city (SP) in 1967, they can cause a lot of environmental damage and deaths. In order to avoid this damage, several methods were proposed to analyze and predict the occurrence of this process. Considering the above, the main objective of this research is to analyze the susceptibility to landslides in the region between Caraguatatuba and São Sebastião (SP), using physiographic compartmentalization and quantitative analysis. In order to achieve these objectives, a physiographic analysis of the study area was carried out by the method of physiographic compartmentalization. Topographic and geological factors, as well as a physiographic comparison were analyzed using percentages of Class Frequency, Scars Concentration and Disproportionality Factor. We tested several scenarios from two different methods in a GIS environment. Method 1 by which the conditioning factors were analyzed through influence weights and Method 2, which maintains the influence weight for the factors and includes weights to the classes of each factor. The physiographic compartmentalization defined 16 units. Our results showed that most of the landslides were concentrated in the Physiographic Unit IV, and a topographic control in the distribution of landslides between 100 and 400 m of altitude, in slopes with declivity between 15 and 30º, composed of migmatite gneiss and granite-gneiss. Method 2 presented significant agreement with the scar mapping of Fúlfaro et al. (1976), and the scenario chosen as more coherent was Scenario O, which presented 60% influence of declivity, 30% hypsometry and 10% geology. The application of the different methods was satisfactory and based on the results we considered the utilization of the physiographic compartmentalization and the probabilistic analysis as important tools in the prediction of susceptibility, thus being able to collaborate with the territorial and environmental management of the cities.

Ma thèse porte sur l'émergence et l'évolution de la RSE au niveau mondial et local dans une perspective institutionnelle. Elle aborde le mécanisme dynamique du champ de la RSE à partir d'une perspective à plusieurs niveaux en trois modes: (1) en tant que gouvernance transnationale, (2) en tant que pratique d'entreprise mondiale évoluée à partir d'une idée ou d'une pratique localement incorporée et (3) en tant que un domaine (quasi-) professionnel. Plus précisément, le premier essai explore les façons dont un État-nation réinvente ses relations avec d'autres acteurs dans le processus de gouvernance transnationale de la RSE. Mon deuxième essai étudie la coévolution des attentes en Corée du Sud en ce qui concerne la responsabilité des entreprises et du système d'affaires national. Mon troisième essai porte sur les mécanismes de micro-professionnalisation du domaine de la RSE en Corée du Sud. D'un point de vue méthodologique, j'utilise des études de cas et des analyses qualitatives pour examiner des ensembles de données composés d'entretiens, d'observations sur le terrain et de données archivistiques. Pour ma thèse, j'ai principalement porté sur 81 interviews de professionnels dans le domaine de la RSE et plus de 200 articles de journaux parlant de la responsabilité des entreprises (ou des riches quand un type moderne d'entreprise n'existait pas en Corée du Sud avant 1960) et “CSR”, qui ont été publiés en Corée du Sud depuis les années 1920, afin de comprendre le champ lui-même et de reconstruire une histoire de l'émergence et de l'évolution du champ. Avec les données que j'ai recueillies, ces trois modes donnent des lignes directrices fondamentales pour mes recherches actuelles et futuresGoing back to the disagreement of Wilensky (1964) in the beginning of this paper, I have some concluding thoughts with respect to my findings. Wilensky (1974) made his stance quite clear by arguing that everyone cannot be professionalized because of quasi-professionals or semi-professionals do not possess tentative knowledge and skills and other conditions as the functionalist approach in the sociology of profession generally argue. Current researchers have argue that contemporary professional fields have lost the essence of professionalism, which is a broad sense of serving societal missions, and have become more interest groups to do their businesses (R. Greenwood, 2007; Saks, 2012). Hence, current established professional organizations are being under de-legitimization and de-institutionalization (Ackroyd, 1996; Brock, 2006). My findings showed that many of CSR professionals, one of emerging quasi-professional groups, tended to share a strong sense of serving societal missions. Some of them (with the strategic corporate giving and the sustainability transition frame) emphasized even more than their business missions, commercial values, and self-interests. Just like any other professionals, some of CSR professionals, especially those within the social innovation and the risk management frame, also underscored the importance of business-like and commercial values to vitalize the CSR field and to grow themselves as stronger professionals. However, they were clearly aware of that what they were doing ultimately generated social benefits, and they appreciated the fact that their professional lives satisfied both their economic interests and societal interests. Hence, their professionalism was actually quite stronger than any other contemporary professionals, which have been criticized for lack of such professionalism. In this regard, why cannot we call CSR professionals, professionals ?

Texto completoResumen
Community, a notion transversal to all areas of Social Network Analysis, has drawn tremendous amount of attention across the sciences in the past decades. Numerous attempts to characterize both the sociological embodiment of the concept as well as its observable structural manifestation in the social network have to this date only converged in spirit. No formal consensus has been reached on the quantifiable aspects of community, despite it being deeply linked to topological and dynamic aspects of the underlying social network. Presenting a fresh approach to the evaluation of communities, this thesis introduces and builds upon the cohesion, a novel metric which captures the intrinsic quality, as a community, of a set of nodes in a network. The cohesion, defined in terms of social triads, was found to be highly correlated to the subjective perception of communitiness through the use of a large-scale online experiment in which users were able to compute and rate the quality of their social groups on Facebook. Adequately reflecting the complexity of social interactions, the problem of finding a maximally cohesive group inside a given social network is shown to be NP-hard. Using a heuristic approximation algorithm, applications of the cohesion to broadly different use cases are highlighted, ranging from its application to network visualization, to the study of the evolution of agreement groups in the United States Senate, to the understanding of the intertwinement between subjects' psychological traits and the cohesive structures in their social neighborhood. The use of the cohesion proves invaluable in that it offers non-trivial insights on the network structure and its relation to the associated semantic.

Apesar da citricultura brasileira deter a liderança mundial na produção de laranjas e de suco de laranja concentrado congelado (FCOJ, frozen concentrated orange juice), observa-se baixo consumo no mercado interno de frutos e de suco in natura, o preferido pelo consumidor brasileiro. Assim, há grande interesse no desenvolvimento de produtos, técnicas de produção e conservação específica para variedades de laranja. As indústrias que produzem suco de laranja a partir do processamento da fruta in natura, conhecido como suco pasteurizado não proveniente do suco concentrado, Not From Concentrate (NFC), enfrentam sérios problemas tecnológicos. As frutas apresentam variabilidade química e sensorial devido às características intrínsecas, podendo variar o sabor e aroma devido às diferentes variedades disponíveis ao longo do ano. O objetivo do presente trabalho foi otimizar o processo da radiação gama em suco de laranja, escolhendo a melhor dose, a fim de reduzir a contagem microbiana e não comprometer as características sensoriais e físico-químicas do suco. Definidas as doses, o objetivo foi avaliar as características microbiológicas, físico-químicas e sensoriais do suco de laranja proveniente de três variedades cítricas, submetido aos processos de pasteurização e irradiação e desenvolver uma terminologia descritiva e o perfil sensorial de suco de laranja. As amostras foram avaliadas por uma equipe treinada de nove provadores e avaliadas quanto à aceitação, com escala hedônica de sete pontos por cinquenta provadores. Tendo em vista os resultados obtidos, a radiação gama e a pasteurização contribuíram para a redução das contagens microbiológicas. No entanto, sensorialmente, os tratamentos com 4,5 e 6,0 kGy foram considerados abaixo do limite de aceitabilidade, quanto ao sabor e à impressão global. As doses estudadas mostraram reduzido impacto sobre as características físico-químicas, independente das variedades cítricas. O tratamento com 3,0 kGy resultou em suco com aroma e sabor acentuado de remédio e cozido, que provavelmente terão influência negativa na aceitabilidade do produtoThe Brazilian citrus is the global leader in production of oranges and frozen concentrated orange juice (FCOJ) there is low domestic consumption of fruits and fresh juice, preferred by brazilian consumers. Thus, there is a great interest by development of products, processes and specific conservation to the cultivation of citrus varieties for the juice\'s production. The industries produce orange juice from the fresh fruit processing, known as pasteurized juice not from concentrate juice (NFC), have serious technological problems. The fruits have chemical and sensory variability due to intrinsic characteristics and can vary the flavor and smell of orange juice because the different varieties available throughout the year. The aim of this study was to optimize the process of gamma radiation in orange juice, picking the best dosage in order to reduce microbiological count and that doesn\'t compromise the sensory characteristics and physicochemical juice. Defined dosages, the objective was to evaluate the microbiological, physicochemical and sensory orange juice from different varieties subjected to pasteurization and irradiation and develop a descriptive terminology and sensory profile of orange juice. The sensorial attributes analysed in this study were appearance, smell, flavor and texture. The samples were evaluated by a trained painel of nine tasters and evaluated for acceptance, with seven-point hedonic scale for fifty tasters. In view of these results, gamma radiation and pasteurisation contributed to the reduction of microbiological counts. However, sensory, treatments with 4.5 and 6.0 kGy were considered the limit of acceptability for flavor and overall impression. The doses studied showed little impact on the physical and chemical characteristics, independent of the citrus varieties. Treatment with 3.0 kGy resulted in juice with aroma and sharp taste of medicine and baked, which will probably have a negative influence on the acceptability of the product

AbstractThe clustering of objects-individuals is one of the most widely used approaches to exploring multidimensional data. The two common unsupervised clustering strategies are Hierarchical Ascending Clustering (HAC) and k-means partitioning used to identify groups of similar objects in a dataset to divide it into homogeneous groups. The proposed Topological Clustering of Individuals, or TCI, studies a homogeneous set of individual rows of a data table, based on the notion of neighborhood graphs; the columns-variables are more-or-less correlated or linked according to whether the variable is of a quantitative or qualitative type. It enables topological analysis of the clustering of individual variables which can be quantitative, qualitative or a mixture of the two. It first analyzes the correlations or associations observed between the variables in a topological context of principal component analysis (PCA) or multiple correspondence analysis (MCA), depending on the type of variable, then classifies individuals into homogeneous group, relative to the structure of the variables considered. The proposed TCI method is presented and illustrated here using a real dataset with quantitative variables, but it can also be applied with qualitative or mixed variables.

AbstractThis study constructs a multi-agent behavior simulation model to explore the quantitative simulation method of waterfront public space. Taking 6 waterfront public space samples along the Huangpu River in Shanghai as research objects, this study first collects environmental data and pedestrian behavior data through field survey, and then analyzes and processes the data to obtain the Spatial Attraction Weight (SWA) that expresses the relationship between pedestrian behavior and spatial elements. Then, based on the Anylogic platform, the pedestrian agent particles expressing people’s characteristics are placed into the simulation environment based on the social force model. They interact in real time to dynamically simulate the pedestrian’s behavior. Finally, fitting verification of the preliminary model is carried out. The qualitative comparison and quantitative correlation analysis are combined to enhance the accuracy. The behavior simulation model of waterfront public space built in the study can more realistically represent the pedestrian's behavior. It can realize the scientific prediction of the future use of waterfront space and provide more detailed reference for problem diagnosis and optimization.

AbstractThis study analyzes the relationship between employees’ paradox mindset and IWB. This study also investigates thriving as mediating variable in the relationships between employees’ paradox mindset and IWB. Individual innovation is accompanied by paradoxical tension. Adopting a paradox mindset, which reflects the extent to which individuals embrace and are energized by tensions, can help people deal with tensions and innovate. Data were collected from 202 banking employees and analyzed using the partial least squares structural equation modeling (PLS-SEM) technique. Findings reveal that employees’ paradox mindset positively affects IWB and is improved when the organization drives the employees to practice thriving at work.

AbstractThis paper presents the assessment results of the spatial relationship between past landslides and four landslide factors in Tinh Tuc town, Cao Bang province, Vietnam, including distance to roads, distance to faults, distance to drainage, and distance to geological boundaries. The fractal dimension values were determined using fractal analyses on three sets of raw data, including the number of landslides, landslide density, and landslide relative density. Using a combination of the frequency ratio (FR) method and the fractal method, landslide susceptibility maps were produced to determine which raw data set more properly analyzes the role of factors in the development of the landslide process. Assessment results using the receiver operating characteristic (ROC) method indicate that the fractal analysis of the raw data sets successfully determines the spatial relationship between conditioning factors and landslides in the study area. In addition, relationship analyses using datasets based on landslide density provide more optimal outcomes. The authors also suggest integrating the fractal method with other quantitative assessment methods to improve the accuracy of landslide prediction in Vietnam and worldwide.

AbstractDigital literature on the Russian-language Internet includes a broad variety of phenomena, from online libraries to writers’ blogs, from hypertext to Internet memes. The chapter begins by clarifying the terms “digital literature” and “Runet,” drawing on a functional understanding of literature in the tradition of Russian Formalism. It embeds Runet literary studies into global contexts and gives an overview of essential phenomena (hypertext, fan fiction, blogging) and narratives. It analyzes local discourses, which, in turn, attempt to make sense of global communication technologies, for example, by conceptualizing digital self-publishing as samizdat, that is, the historical phenomenon of clandestine underground publication in the post-Stalin Soviet Union. The chapter concludes with an overview of research approaches and methods, both qualitative and quantitative, and of the challenges that future analysis will face.

AbstractResidential areas, as the main places for urban population activities, are the basic spatial units for reducing carbon emissions. The mix of residential land use functions is closely related to residents’ daily travel. This paper takes the Gaoshui district of Mianyang city as an example, uses carbon emissions as a measurement tool, constructs a family travel carbon emission quantitative estimation model and a land use function mix calculation model, compares and analyzes the differences in residents’ travel behavior in each sample area, and uses a linear regression model to analyze the impact of function mix on residents’ travel behavior. The results show that there are spatial differences in residents’ shopping, entertainment, medical treatment, commuting and other travel behaviors in the 12 sample areas; the function mix has no significant impact on family commuting carbon emissions, but has a significant negative impact on non-commuting carbon emissions, and mixed development of residential areas has a positive significance for reducing carbon emissions.

Abstract This article analyzes the performance of object detection algorithms in detecting flaws in welds inspected by X-ray testing. We propose a learning framework that relies on both experimental acquisitions and simulations to build a training set of images with virtual flaws. This set is then used to fit object detection algorithms aiming at detecting flaws in welds. After training, we analyzed the machine learning performance against real flaws in welds using experimental X-ray testing images that were not included in the training process.

Texto completoResumen
The article describes a quantitative analysis of the numerical values of thermal efficiency obtained in a full-scale experiment under conditions of negative ambient temperatures. The essence of quantitative analysis is the statistical processing of measurement results. The nonparametric Mann-Whitney test was chosen as a mathematical statistics tool. The experiment consisted in comparing the thermal efficiency of an electric torch device of a diesel engine when burning two fuels of different fractions (diesel fuel and automotive propane). The obtained results of the experiment are represented by two general sets of flow air temperatures: when the electric torch device is operating on diesel fuel and on propane automobile. Consistency and adequacy of the results of quantitative and qualitative analyzes determined the advantages of fuels of light fractional composition in relation to diesel fuel.

Texto completoResumen
Pipeline stations, as an important part of long-distance pipeline systems, include lots of facilities which are highly concentrated and always operate continuously. Risk assessment is an important foundation work for the risk management of these stations. Since various uncertainties exist during the quantitative risk assessment (QRA), this paper explores the theories and approaches of QRA for station accidents, and also introduces some specific mathematical theories for quantification and dealing with uncertainties. This paper combines uncertainty theory effectively with the QRA for gas distribution stations, analyzes the uncertain factors in the QRA of gas distribution station, and establishes Bayesian update model for estimating basic events’ failure rates and probabilities of failure on demand based on generic failure data and plant-specific data. And it also offers conversion method among conjugate prior distribution of different types. Besides, probabilistic estimation model is set up by the combination of fuzzy set theory, expert judgments and fuzzy group decision making. The paper builds Fuzzy Bow-Tie quantitative model for distribution station under dependency relationships, and proposes the sensitivity analysis method for the accident model based on fuzzy importance index, fuzzy uncertainty index and minimal cut sets importance index.

Texto completoResumen
Supervised learning methods from machine learning are starting to be widely used in oil & gas data management. The usage of the method is adjusted to the purpose of data processing, including data classification and regression. In this research, there are six classification methods to estimate the electrofacies shape, lithology type, and fluids, namely Decision Tree (DT), Gaussian Naïve Bayes (GNB), K-Nearest Neighbors (KNN), Random Forest (RF), Support Vector Machine (SVM), and Gradient Boosting (XGB). This research compared those six methods qualitatively and quantitatively to obtain the best method. This research was conducted in the Maju Royal Field using one oil well data for training data and another one well as testing data. For validation purposes, 85% of the data was split for training and 15% for validation, aiming to evaluate the machine learning model through the correlation coefficient value. In the test data, qualitative and quantitative analyzes were also conducted. Qualitative analysis was performed by comparing the results of the electrofacies shape prediction with the original interpretation, lithology prediction with shale volume data, and prognosis of fluids with test zone data. Meanwhile, quantitatively, it is done by comparing the correct predictive data with the actual amount of data on each parameter. The training data evaluation result shows that KNN and XGB are suitable for electrofacies shape prediction. Meanwhile, lithology and fluid estimation are good with DT, KNN, and XGB methods. The qualitative and quantitative analysis result from the test data shows that the DT and GNB methods are suitable for estimating the electrofacies shape. In contrast, all methods are considered good at predicting and have good correlation values for calculating the lithology and fluids. Hence, both training and test data evaluation result has good correlation values

Texto completoResumen
Six-legged robots are reliable locomotive machines with actuation redundancy. This paper analyzes the force and velocity capacities of a six-legged high-payload robot geometrically and numerically. The full-body Jacobian between the body platform and the actuation is first of all computed. A geometric computation approach is then proposed to obtain the robot velocity/force polytopes in the platform operational space. System physical constraints of joint torques and velocities are taken into account so that the task space capacities could be quantitatively given. Besides, several capacity indices are also investigated, including the maximum velocity/force magnitude, the maximum velocity/force along a given direction and the maximum isotropic velocity/force. At last, the robot capacities are numerically analyzed with different supporting legs. The results verify high payload capacity of the robot and clarify the influence of different gait parameters on the task space performance. Our method is proposed in a general and convenient framework, and therefore it is beneficial for the quantitative performance evaluation of any multi-legged walking machine with actuation redundancy.

Texto completoResumen
Decision-making in architectural design is a complex process that includes factors such as aesthetics, environmental, and user needs (Gercek and Arsan, 2019). Utilizing computational simulation tools is one way to gather quantitative data efficiently to help architects in this process (Reinhart and Fitz, 2006). Recent literature on decision-making in architectural design states that it is significant for architects to create a link between their professional experience gained from previous work and knowledge provided from simulation tools (Gercek and Arsan, 2019). Daylight simulation tools are regularly accepted in the market, since it is difficult to evaluate the quantity of daylight in a space through a simple equation (Reinhart and Fitz, 2006). Whether the daylight simulation is done in-house or by a consultant, it is imperative for architects to have empirical knowledge about how the numerical results relate to the user experience. In this article, a set of methods is proposed to improve designers’ understanding of daylight simulation results. The study has been conducted in July and August of 2019. The methods used in this study are survey, daylight simulation, and daylight measurement via environmental monitoring. The participants who are designer/occupants in a design firm in Raleigh, North Carolina, USA, participate in an online survey asking about their productivity and visual comfort in the space. Daylight simulation analyzes the illuminance levels in the office space with Ladybug and Honeybee - plug-ins of Rhino Grasshopper. Furthermore, the actual illuminance in the space is measured by Omron 2JCIE-BL01 sensors in certain locations for additional empirical evidence. A correlational analysis is conducted between the questions of the survey, its results shows that there is no statistically significant correlation between visual comfort and employees’ perception of productivity in the summer. Also, the data gained from the sensors and survey show that the daylight is not equally distributed across the office, ranging from 100-1500 lux. Ultimately, by sharing the findings with the participants in the meeting, while conducting the realtime daylight simulation, they can relate results to their own experience in space. It helps them improving their design knowledge and process for meaningfully integrating daylight in their design.

Texto completoResumen
This paper provides an estimation of the size of income and demand automatic stabilizers in a representative sample of Latin American and Caribbean (LAC) countries. The authors find that when a negative unemployment shock hits the economy, the size of income and demand automatic stabilizers coefficients is much smaller than the size of these coefficients in Europe and the United States. This evidence suggests that there is room for policies that can enlarge the absorption by these coefficients as a way to contribute to macroeconomic stability in LAC countries. The paper analyzes four policies affecting the income stabilization coefficient and two others affecting directly the demand stabilization coefficient. The main results suggest that changing the minimum tax exemption and its progressiveness using the tax structure of middle-income countries outside the LAC region is the best option to enlarge the size of the income and demand stabilization coefficients, and in this way to reduce the need of discretionary fiscal policies in theregion.

Recently, the Junichiro Koizumi and Shinzo Abe administration has adopted labor reforms, and monetary authorities have updated unconventional monetary policies: quantitative easing of money supply and negative interest rate control. It can be identified that quantitative easing policy and negative interest rate policy have introduced and stimulated new styles of profit-seeking through stock market transactions, which only increases corporate and bank profits under a stagnant labor productivity growth rate. Under such a context, this paper analyzes the changing phase of the profit-seeking patterns of the financial and non-financial sector in Japan. The hypothesis is that the large-scale corporate sector has created a new profit-seeking paradigm and that this has been supported by the monetary control of the so-called "Abenomics".

Texto completoResumen
The present study reviews the recent Chilean experience in the design and execution of the Progressive Housing Program initiated in 1990 and its recent evolution towards the programs: Solidarity Housing Fund (Fondo Solidario de Vivienda) and Dynamic Social House without Debt (Vivienda Social Dinámica sin Deuda). This experience confronts many of the key themes identified in the previous paragraphs and its analysis provides significant lessons for the design and execution of similar programs in other countries of the region. The study explores the evolution of the Chilean housing policies in support of the progressive construction of housing starting in the 1950s, but concentrating on the experience of the last twelve years of execution of the Progressive Housing Program. Additionally, it analyzes the operative mechanisms used, document quantitative results in terms of numbers of houses supported and the qualitative results comparing the current situation of housing subdivisions and specific homes with the initial solution received from the program.

This paper analyzes quantitative findings on the innovative behavior of firms in the production chains of pisco and shoe manufacture in Peru, which are served by the network of Technological Innovation Centers (CITEs), the most important technology policy instrument available in Peru. These two chains, in low and medium-technology industries, are representative of Peru's manufacturing sector. Of particular interest is the role of technical standards as a means of technological diffusion, which is stressed in the work of the CITEs. For the pisco chain, that role involves the definition of the product itself, for which Peru is seeking a World Intellectual Property Organization (WIPO) denomination. In the shoe chain, the technical standard should act as a coordination mechanism that will help increase efficiency throughout the chain, which at present is often fractured.

Texto completoResumen
This paper analyzes claims that the Federal Reserve is principally responsible for the decline of inflation in the U.S. We compare several different quantitative approaches. These show that at most the Fed could plausibly claim credit for somewhere between twenty and forty percent of the decline. The paper then examines claims by central bankers and their supporters that a steadfast Fed commitment to keeping inflationary expectations anchored played a key role in the process. The paper shows that it did not. The Fed’s own surveys show that low-income Americans did not believe assurances from the Fed or anyone else that inflation was anchored. Instead, what does explain much of the decline is the simple fact that most workers nowadays cannot protect themselves by bargaining for higher wages. The paper then takes up the obvious question of why steep rises in interest rates have not so far led to big rises in unemployment. We show that recent arguments by Benigno and Eggertson that shifts in vacancy rates can explain this are inconsistent with the evidence. The biggest factor in accounting for the strength in the economy is the continuing importance of the wealth effect in sustaining consumption by the affluent. This arises, as we have emphasized in several papers, from the Fed’s quantitative easing policies. Absent sharp declines in wealth, the continuing importance of this factor is likely to feed service sector inflation in particular.

Texto completoResumen
Our study analyzes the impact of debt moratorium policies, possibly the oldest approach to addressing repayment problems. Using Colombian administrative data, we compare firms that narrowly met the criteria for moratoria (eligible firms could not exceed 60 days overdue on their loans) with those that just missed it. Our findings reveal that stressed firms accessing moratoria experience more favorable loan conditions on subsequent borrowing, characterized by higher loan amounts and lower interest rates. This credit relief, in turn, contribute to substantial increases in firm investment and employment. To delve deeper into the implications, we employ a quantitative general equilibrium model of default to assess both short- and long-term effects. While these policies effectively mitigate liquidity concerns, they concurrently elevate default risks. Notably, our research underscores larger welfare gains when debt moratorium policies incorporate interest forgiveness during periods of debt standstill by reducing default risk.

Texto completoResumen
This article has three goals. First, it describes the genesis of fiscal rules in Peru and its degree of compliance. Second, it estimates the effect of fiscal rules adoption on public investment. Last, it analyzes the impact of alternative fiscal rules on public investment and public debt sustainability. Our main results are as follows. First, the implementation of fiscal rules in the year 2000 caused a 60 to 80 percent fall in public investment relative to several counterfactuals. Second, our DSGE model suggests a Structural Fiscal Rule would have increased the consumers welfare in the period 2000-2019 more than other fiscal designs. This rule reduces the procyclicality of public investment under commodity price shocks and macroeconomic volatility under world interest rate shocks. Third, a Structural Fiscal Rule has the lowest probability of exceeding the current public debt limit (30 percent of GDP), although there is a trade-off between investment-friendly rules and fiscal sustainability issues. Nevertheless, our quantitative results are limited to short spans of analysis. With a long-run perspective, we may say that fiscal rulesdespite constant modifications and recurring non-compliancehave fulfilled their original and most important goal of achieving the consolidation of public finances.

This report analyzes anticipated list mile challenges in Indiana by using a scenario-based approach to develop forecasts of GDP growth and thus freight growth across industry clusters in Indiana counties; potential congestion implied by this growth; and a proactive plan to add capacity to alleviate the congestion. We use a quantitative approach to aggregate ramp level flows, industry cluster locations, county layout, and economic activity to develop our recommendations. We develop forecasts through the year 2050 based on long-term planning approaches used by other states (California, Ohio, and Utah). We use data from global databases that consider different possible geo-political scenarios and regulatory choices to scale it down to county-level impact. At the same time, we track industry cluster locations within each county, ramps from interstates, and distances to travel within the counties to reach freight destinations. The result is a report that combines macro trends with micro detail to develop potential capacity bottlenecks.
