Towards a Blockchain Weather Derivative Financial Instrument for Hedging Volumetric Risks of Solar Power Producers
Authors: Alao Olakunle , Cuffe Paul
Published: May 2021

The weather-dependent nature of solar power makes Solar Power Producers susceptible to the unpredictability of sunshine. Temperature-based weather derivatives have recently emerged as an effective volumetric risk cross-hedge for Solar Power Producers, given that temperature positively correlates with solar radiation. Temperature-based put and call options, mostly traded on organized exchanges, require users to pay premiums that are costly and difficult to price. Swap contracts can serve as an economical alternative since they do not require premiums. However, they are only traded over-the-counter and are thus illiquid and liable to counterparty credit risks. For these reasons, a novel blockchain temperature-based weather derivative swap marketplace is proposed that mitigates the risks inherent in traditional swap contracts. The payoff structure and governing mechanisms of the smart contract that underpins this instrument are also developed. A preliminary investigation of this new financial instrument shows its efficacy in hedging volumetric risks of Solar Power Producers.
Nos passos do Bon-Odori
Authors: Arraes Gomes Vitor
Published: May 2021

The aim of this article is to investigate the cultural plurality of Bon-Odori in the city of Marília / SP. Preliminarily, it’s known that this phenomenon is a ritual of Japanese origin and celebrates the spirits of the dead by the sacred circular dance. In the Midwest and Northwest cities of São Paulo, this ritual takes place in annual events organized by Japanese-Brazilian communities. Thus, the description of this ritualistic practice proved to be indispensable to capture the dynamics of its functioning system, and to understand the socio-cultural representations that compose it. Even of a foreign origin, the Bon-Odori practiced in the Midwest and Northwest of São Paulo would assume another feature due to the Nikkey culture: a symbolic system that integrates Japanese and Brazilian cultures. In a methodological point of view, the research applied a participant observation, in addition, photographs and videos of the events were necessary to understand the dances. In anthropological terms, it was concluded that in Brazil the Bon-odori is no longer a strictly Japanese phenomenon, but a Japanese-Brazilian ritual of sacred circular dance, because the ethnic-cultural differences are mixed in its social composition.

The article "Nadir Shah's determination to statehood" is a scientific analysis of Nadir Shah's legacy of statehood, his historical perspectives, and state-building resources in general, who fought strongly and decisively for the ideas of Azerbaijanism and the renaissance of statehood. In short, the exceptional services of this great and powerful commander in the history of Azerbaijan have been studied from a wide angle. The article highlights Nadir Shah's success, ability and restraint in state and military affairs as a special case. It is not overlooked that these processes played a significant role in the Shah's determination to win, emphasizing security as a key issue. It turns out that Nadir Shah, like Shah Khatai, had always considered the internal strife that dragged our country into the abyss to be extremely urgent, and used his political wisdom, rich management experience, rescue and creative mission to conquer large areas in difficult, extreme conditions. Basically, he took decisive steps to solve these fateful tasks quickly, and the implementation of his multi-vector action plan was one of the important tasks for Nadir Shah at that time. Key words: Nadir Shah, Tahmasib, Khatai, statehood, warlord

Animation is a Latin word meaning animation in our language. It is taken from the French word "Anime" and is located in our language. In French, the word "anime" means animation. Animation generally involves all animation systems. Even the animation of an animal by a group of actors on the stage is a form of animation. Computer-generated cartoons, etc. animations are also called animations. Today such animations are used for television and cinema. If we want to look for animation as a paragraph, we should look for it in the section "Entertainment services in tourism". In order to ensure that tourists have a good time and increase the demand for work, great efforts are made to use all the animations as a result. Any entertainment, to present an interesting program, is a set of all activities aimed at activating guests, that is, all animation activities. "Animator" is used in the sense of a person who animates, performs and moves. Animation has emerged as a social phenomenon. Since primitive communities, animations have been used in various ceremonies. Animations made using face painting, masks and accessories are still very common. It has become an indispensable element of gatherings and events. Although it has undergone certain changes over time, animation is a social activity that retains all the animating power it seeks to convey to people.

Published: May 2021

Wearable triboelectric nanogenerators (TENGs) have recently attracted great interest because they can convert human biomechanical energy into sustainable electricity. However, there is a need for improvement regarding the output performance and the complex fabrication of TENG devices. Here, a triboelectric nanogenerator in single-electrode mode is fabricated by a simple strategy, which involves a sandwich structure of silicone rubber and silver-coated glass microspheres (S-TENG). The S-TENG exhibits a remarkable performance in harvesting human motion energy and as flexible tactile sensor. By optimizing the device parameters and operating conditions, the maximum open-circuit voltage and short-circuit current of the S-TENG can reach up to 370 V and 9.5 μA, respectively. The S-TENG with good stretchability (300%) can be produced in different shapes and placed on various parts of the body to harvest mechanical energy for charging capacitors and powering LED lights or scientific calculators. In addition, the good robustness of the S-TENG satisfies the needs of reliability for flexible tactile sensors in realizing human–machine interfaces. This work expands the potential application of S-TENGs from wearable electronics and smart sensing systems to real-time robotics control and virtual reality/augmented reality interactions.

Este início de milênio vem permitindo o aumento vertiginoso do fluxo de informações por todo o planeta. Com isso, o acesso das pessoas a conhecimentos tecnológicos e de mercado não só aumentou, como pode ser disponibilizado praticamente em “tempo real”. Contudo, a despeito de toda evolução dos meios informacionais, o mundo vem se tornando cada dia mais excludente. Ao mesmo tempo que a sociedade procura formas mais competitivas de “saber fazer” também existe o desafio de se pensar em “para que “e “para quem”. Talvez por isso, uma parte dos debates do Brasil atual estão centrados em repensar muitos conceitos, fazendo com que muitos debates do meio acadêmico ganhem um espectro mais visível para a vida das pessoas. No setor rural este desafio ganha contornos próprios. Inicialmente tem-se que admitir que o universo rural brasileiro é complexo e que muitas tipologias já não conseguem ser abrangentes o suficiente seja para entender o contexto atual e, principalmente, para auxiliarem na formulação e operacionalização de políticas e ações públicas. Neste sentido, temas como agricultura familiar, desenvolvimento sustentável e gestão social são inerentes a qualquer debate em torno do rural brasileiro.

Published: May 2021

As chamadas plantas bioativas são consideradas aquelas que possuem alguma ação sobre outros seres vivos e cujo efeito pode manifestar-se tanto pela sua presença em um ambiente quanto pelo uso direto das substâncias extraídas, desde que mediante uma intenção ou consciência humana deste efeito. Dentro deste conceito, estão as plantas medicinais, condimentares, aromáticas, inseticidas, repelentes, tóxicas, entre outras. O estudo destas plantas tem despertado um grande interesse nos últimos anos, em função, principalmente, de seu aproveitamento na agroecologia e, de uma forma mais recente, da criação da Política Nacional da Plantas Medicinais e Fitoterápicos. As plantas bioativas apresentam-se com potencial para o manejo da Bemisia tabaci, principalmente nos cenários de produção agroecológica. Dentre essas plantas, a citronela (Cymbopogon nardus) evidencia-se com elevado potencial devido sua ação repelente, já elucidada. Na busca por mecanismos agroecológicos de manejo da mosca branca em sistema de produção orgânica, este capítulo tem o objetivo de analisar o potencial de repelência do extrato de citronela sobre mosca branca no cultivo de tomateiro em ambiente protegido.

Published: May 2021

A pandemia da COVID-19 impactou negativamente os produtores rurais de forma multidimensional: saúde, produção, comercialização, renda e formas de comunicação. Por outro lado, os produtores rurais nessa pesquisa mostraram relativa capacidade de superação para enfrentar os desafios impostos. Muitos produtores e seus familiares e conhecidos foram infectados com o Sars-CoV-2. Assim, este estudo teve como objetivo analisar o impacto causado aos agricultores familiares devido a pandemia – COVID-19 frente aos programas de políticas públicas do Governo Federal PAA e PNAE na região dos Campos Gerais – PR. A metodologia inicialmente procurou uma revisão bibliográfica dos estudos mais recentes sobre os impactos causados na agricultura familiar com relação a pandemia da COVID-19; participaram desta pesquisa 68 produtores rurais, bem como Secretaria Municipal de Educação e Secretaria Municipal de Agricultura da região dos Campos Gerais – PR com dezenove cidades. Os resultados indicaram que a maior parte dos produtores rurais (86%) declarou que tiveram pessoas próximas infectadas, oscilando de dez pessoas ou mais entre familiares conhecidos e/ou o próprio produtor rural. À guisa da conclusão para esse estudo, foi possível identificar que alguns perderam amigos e parentes para a doença, além de sofrerem perdas na produção e quedas na venda e renda, mas nenhum(a) produtor(a) teve perda total da produção ou queda total de vendas.

Published: May 2021

A expansão do agronegócio no cerrado piauiense ocorre de forma intensa e voraz, alterando a velocidade de interação do ser humano com a natureza, desrespeitando o tempo biológico desta, ajustando-a à impaciência da reprodução do capital. Com efeito, severas são as implicações sobre o trabalhador e os recursos naturais. Diante disso, o presente trabalho tem como objetivo elucidar a categoria superexploração da força de trabalho rural no setor produtivo da soja em Uruçuí-PI, com vistas a provocar reflexões acerca da realidade recente da força de trabalho rural piauiense, no intuito de compreender o seu papel na dinâmica produtiva da economia global e suas implicações no mercado de trabalho nacional e mundial. Tem-se como método de investigação e análise a Teoria Marxista da Dependência, buscando se investigar nas relações sócio produtivas estabelecidas pelo agronegócio, a categoria da superexploração da força de trabalho, desenvolvida por Ruy Mauro Marini. Como resultado, o estudo evidenciará o caráter dialético do capital agrário piauiense, onde os trabalhadores rurais produzem riquezas “alheias” e se apropriam tão somente de suas misérias, evidenciando, portanto, a tese de Marini.

Published: May 2021

As feiras livres são acontecimentos frequentes que ocorrem em espaços públicos (praças e ruas) e caracterizam-se por ser um canal de comercialização dos produtos da agricultura familiar.Com objetivo de caracterizar os feirantes da agricultura familiar e compreender a percepção e o comportamento dos consumidores sobre a feira aplica-se um questionário, com questões objetivas e subjetivas. A análise relaciona o gasto dos consumidores com fatores socioeconômicos e com a satisfação em relação à feira da agricultura familiar que acontece na praça Dedé Serpa, localizada na sede do município de São Lourenço do Sul-RS, Brasil. A pesquisa realiza-se entre junho de 2015 e maio de 2017. Foram convidados e submetidos à pesquisa 14 feirantes e 60 consumidores. De acordo com os feirantes, a vantagem principal de comercializar na feira é a eliminação do atravessador, outras vantagens citadas foram: clientes fixos, preço justo, pagamento à vista e possibilidade de interagir com os consumidores. Os consumidores com ensino superior e pós-graduação apresentam maior gasto na feira, o qual não foi influenciado pelo vínculo de trabalho e sim pela renda. Esses consideram que a feira é um local centralizado, de fácil acesso, que oferece produtos orgânicos, é organizada e limpa, com atendimento bom e confiável, espaço de sociabilização e, sobretudo, porque a feira representa uma tradição do município. Os feirantes e consumidores demonstram satisfação com a feira e desejam a sua continuidade.

O objetivo deste trabalho foi avaliar a percepção dos produtores rurais do Assentamento Paulo Fonteles quanto ao acesso às políticas públicas de desenvolvimento socioeconômico por meio de um estudo de caso, utilizando o índice de vulnerabilidade social através da metodologia SEA. A área de estudo é o Assentamento Paulo Fonteles que se localiza na cidade de Belém-PA, no distrito de Mosqueiro, com acesso pela estrada da Baía do Sol, bairro Sucurijuquara. Os dados foram coletados no ano de 2019, através de uma abordagem mista, com levantamentos quantitativos e qualitativos de fatores básicos que podem ter reflexos de intervenções governamentais, onde para cada fator avaliado foi estipulada uma pontuação que varia de 01 a 05, de muito baixo a muito alto, comparando os dois períodos de análise (2006 e 2019). Foi obtido o índice de vulnerabilidade social que varia de 0 a 1, onde quanto mais próximo de 1 a avaliação será melhor. Observou-se que houve taxa de crescimento de 97,3 % em relação ao índice de vulnerabilidade social de 2006 para 2019. Os atributos que contribuíram para esse aumento foram idade, grau de escolaridade, acesso a moradia, destino do lixo e esgoto e acesso a água potável. Já o índice de acesso às políticas governamentais continuou com o mesmo valor de 1, muito baixo, demonstrando a deficiência do poder público nas áreas de assentamentos rurais. Desse modo, a análise realizada comprova que ocorreram melhorias socioeconômicas para os produtores, mostrando a eficácia do índice de vulnerabilidade social na avaliação.

A irrigação subterrânea é promissora para uso em regiões com escassez de água, uma vez que a água pode ser transportada diretamente para as raízes das plantas, com pouca perda por evaporação superficial. Este trabalho apresenta como alternativa a utilização de resíduos têxteis para aplicação na agricultura propor uma solução sustentável para a destinação dos resíduos da indústria da moda que costumam ser jogados no lixo, gerando problemas ambientais. O desenvolvimento da tecnologia simples de irrigação subterrânea baseada em resíduos têxteis, aqui apresentada, levou ao uso racional da água em canteiros experimentais construídos, sem aparentes prejuízos ao desenvolvimento das lavouras, o que pode fortalecer a agricultura familiar e ter impacto significativo sobre a crescimento econômico da região, se a tecnologia for aplicada em escala. De maneira geral, todos os resultados experimentais de campo demonstraram que os dispositivos desenvolvidos com pedaços de resíduos têxteis sintéticos foram capazes de transportar água para áreas distantes do solo, mantendo-a úmida na raiz e contribuindo para um melhor crescimento das plantas testadas. Ou seja, todos os dispositivos construídos para viabilizar a irrigação subterrânea de tecidos por capilaridade funcionaram adequadamente, em uma análise qualitativa. Os dispositivos idealizados e testados têm em comum o fato de serem tecnologias de base, de baixo custo, fáceis de construir, implementar e manter; simplicidade; possibilidade de domínio da tecnologia pelos próprios beneficiários; e geradores de conhecimento compartilhado entre proponentes e beneficiários. Em suma, potenciais geradores de impacto social para essa população que tanto precisa de soluções inclusivas.

O município de Uruçuí é um grande produtor de grãos (soja, milho), possui grande potencial e está em processo de crescimento. A cultura do amendoim é pouco explorada no município, cultivada apenas por pequenos produtores. Além disso, os produtores sofrem com baixa produtividade, isso se deve, principalmente, ao uso de cultivares inadequadas. Existem poucos estudos e informações a respeito dessa cultura nessa região. Objetivo: Avaliar o desempenho agronômico de cultivares de amendoim, visando selecionar os mais promissores e indica-los para o cultivo no município de Uruçuí-PI. Métodos: O delineamento experimental utilizado foi em blocos casualisados com quatro repetições e cinco cultivares: BR 1, BRS 151 L7, BRS Havana, IAC TATU ST e Runner IAC 886. O solo foi preparado utilizando-se um motocultivador e a adubação utilizada foi 266 Kg ha-1 da formulação 3-30-15 e 33,5 Kg ha-1 de cloreto de potássio. O plantio foi realizado dia 20 de janeiro de 2018 em sulcos com 5 cm de profundidade. Nos primeiros 15 dias foi necessário fazer irrigação e posteriormente a cultura foi conduzida sem irrigação complementar. A colheita foi realizada após 111 dias do plantio e avaliou-se as seguintes variáveis: teor de umidade dos grãos, massa fresca e seca das plantas, número de vagem por planta, produtividade de vagens, produtividade de grãos e o rendimento de grãos. Os dados obtidos foram submetidos à análise de variância. Resultados: Observou-se que não houve diferença entre as cultivares para todas as variáveis. Conclusão: Todas as cultivares obtiveram boa produtividade e são recomendadas para o cultivo na região de Uruçuí-PI. A cultivar IAC TATU ST, obteve desempenho numericamente superior em relação as outras cultivares, chegando a produzir no mínimo 600 Kg ha-1 a mais de vagens comerciais.

O objetivo do trabalho foi investigar a importância da educação nos Assentamentos Rurais da Microrregião de Andradina e analisar os programas oferecidos pelo governo e as dificuldades dos assentados ao seu acesso. Aplicou-se 20 questionários para famílias de 12 Assentamentos. O trabalho foi documentado por meio de tabela e gráficos. O nível de escolaridade das mães é superior ao nível de escolaridade dos pais. As famílias são constituídas com pais na faixa etária de 40 – 50 anos e mães na faixa etária de 30 – 40 anos. A maioria das escolas dos Assentamentos oferecem apenas o Ensino Fundamental I. Dos 12 Assentamentos, 7 não oferecem transporte escolar. Há oferecimentos de cursos de capacitações da área do agronegócio, entretanto, é pouco o interesse por parte da comunidade assentada na participação dos mesmos. Grande parte dos responsáveis pelos lotes possuem ensino fundamental ou ensino médio incompleto e as escolas existentes nos Assentamentos não oferecem cursos como o EJA, que se constitui numa chance para os assentados que, por qualquer motivo, não concluíram o ensino na idade apropriada. Há cursos de capacitação da área de agronegócio oferecidos pelos órgãos dos governos, porém é pouco o interesse por parte dos assentados em participar dos mesmos.

Amaç: Kemik mineral yoğunluğu ölçümleri ile trombosit endeksleri arasında bir ilişki olup olmadığını araştırmak

Gereç ve Yöntemler: Postmenapozal kadınlar arasından osteoporoz olan ve olmayanların kemik mineral yoğunluk ölçümleri ve ölçüm günü bakılan trombosit endeksleri retrospektif olarak kaydedildi. Trombosit endeksleri olarak trombosit sayısı, ortalama tombosit hacmi ve trombosit dağılım genişliği değerleri not edildi.

Bulgular: Osteoporoz olanlarda ortalama trombosit hacmi ve trombosit dağılım genişliği olmayanlara göre anlamlı derecede daha fazlaydı. Bu iki trombosit endeks değerleri ile lumbar 1-4 vertebra ve Femur total kemik mineral yoğunluğu değerleri arasında negatif yönde ilişki mevcuttu.

Sonuç: Kemik mineral yoğunluğu değerleri ile ortalama trombosit hacmi ve trombosit dağılım genişliği değerleri anlamlı ilişki mevcuttur. Bu durum kemik metabolizması ile trombosit metabolizmasının bağlantılı olduğunu düşündürmektedir.
The Intrinsic Scatter of Galaxy Scaling Relations
Authors: Stone Connor , Courteau Stéphane , Arora Nikhil
Published: May 2021

We present a compendium of disk galaxy scaling relations and a detailed characterization of their intrinsic scatter. Observed scaling relations are typically characterized by their slope, intercept, and scatter; however, these parameters are a mixture of observational errors and astrophysical processes. We introduce a novel Bayesian framework for computing the intrinsic scatter of scaling relations that accounts for nonlinear error propagation and covariant uncertainties. Bayesian intrinsic scatters are ∼25% more accurate than those obtained with a first-order classical method, which systematically underestimates the true intrinsic scatter. Structural galaxy scaling relations based on velocity (V
23.5), size (R
23.5), luminosity (L
23.5), color (g − z), central stellar surface density (Σ1), stellar mass (M
*), dynamical mass (M
dyn), stellar angular momentum (j
*), and dynamical angular momentum (j
dyn) are examined to demonstrate the power and importance of the Bayesian formalism. Our analysis is based on a diverse selection of over 1000 late-type galaxies from the Photometry and Rotation Curve Observations from Extragalactic Surveys compilation with deep optical photometry and extended rotation curves. We determine the tightest relation for each parameter by intrinsic orthogonal scatter, finding M
* − V
23.5, R
23.5 − j
*, and L
23.5 − j
dyn to be especially tight. The scatter of the R
23.5 − L
23.5, V
23.5 − (g − z), and R
23.5 − j
dyn relations is mostly intrinsic, making them ideal for galaxy formation and evolutionary studies. Our code to compute the Bayesian intrinsic scatter of any scaling relation is also presented. We quantify the correlated nature of many uncertainties in galaxy scaling relations and scrutinize the uncertain nature of disk inclination corrections and their effect on scatter estimates.
New Evidence for Extended He ii Reionization at z ≳ 3.5 from He ii Lyman Alpha and Beta Transmission Spikes*

Published: May 2021

We present new high-resolution (R = λ/Δλ ∼ 14,000) spectra of the two brightest He ii-transparent quasars in the far-UV at z
em > 3.5, HE2QS J2311−1417 (z
em = 3.70) and HE2QS J1630+0435 (z
em = 3.81), obtained with the Cosmic Origins Spectrograph on the Hubble Space Telescope. In the predominantly saturated He ii absorption spectra, both sight lines show several isolated resolved (FWHM ≳ 50 km s−1) transmission spikes in He ii Lyα and He ii Lyβ. The incidence of such spikes decreases with increasing redshift, but both sight lines show significant spikes at z ≳ 3.5, signaling the presence of fully ionized regions in the z ≳ 3.5 intergalactic medium (IGM). We employ an automated algorithm to compare the number of detected He ii transmission spikes to predictions from mock spectra created from the outputs of a cubic (146 cMpc)3 optically thin Nyx hydrodynamical simulation, assuming a range of UV background photoionization rates ΓHe II
. From the incidence of Lyα and Lyβ transmission spikes we infer similar photoionization rates of

at 3.51 < z < 3.66 and ΓHe II
= (0.9 ± 0.3) × 10−15 s−1 at 3.460 < z < 3.685, respectively. Because the transmission spikes indicate fully ionized regions at z ≳ 3.5 along both lines of sight, our observations provide further evidence that He ii reionization had substantially progressed at these redshifts.
Psychanalyse de l’enfant, pédopsychiatrie et psychothérapie : enjeux actuels

Published: May 2021

Les attaques contre la psychanalyse visent également aujourd’hui la pédopsychiatrie. Il est vrai que celle-ci doit beaucoup à la psychanalyse en France, permettant une prise en compte de la structuration psychique en termes psychopathologiques et jusque dans la classification française, maintenant interfacée avec la CIM 10. Si certains psychanalystes s’en sont défiés, l’évaluation de l’action de la psychanalyse est aujourd’hui vitale, et ce défi peut être relevé. La spécificité de la psychanalyse de l’enfant est discutée au sein de la psychanalyse et vis-à-vis des psychothérapies. Le problème épistémologique est posé du point de vue intrapsychique freudien quant à pouvoir rendre compte de l’aube de la vie psychique avant l’établissement d’une limite dedans/ dehors. Les conséquences des modifications sociétales sont également envisagées ; elles interrogent la transmission du surmoi. La spécificité de la formation à la psychanalyse de l’enfant est proposée, dégagée de l’enjeu de transmission de la cure.
An Examination and Comparison of Stethoscope Hygiene in Nursing Education Programs
Authors: Gaisser D'Arcy J. , Lowey Susan E. , Barbel Paula
Published: May 2021

Background:

Improper stethoscope hygiene has been found to contribute to the development of health care associated infections, which affects approximately one in every 30 hospitalized patients. Various pathogens have been found on the stethoscopes of health care workers.

Method:

A correlational descriptive design was used to compare stethoscopes from 117 nursing students. Sterile swab samples were obtained from four separate areas of each stethoscope. Samples were plated and incubated for 24 to 48 hours.

Results:

Bacteria were found on all parts of the stethoscopes from both undergraduate and graduate nursing students, with the earpiece having the highest percentage of contamination. Staphylococcus was the most prevalent microbe found on all four swab sites.

Conclusion:

Educating students about stethoscope hygiene and consistently reinforcing it in practice are essential to reduce the transmission of pathogens in the health care environment. Nurses can model best practice with students and other disciplines to increase the likelihood of adherence.

Transition of a Collaborative In-Person Health Care Innovation Course to Online Learning
Authors: Karwat Ariel , Richmond Therese S. , Leary Marion
Published: May 2021

Background:

As COVID-19 forced in-person courses to transition online, an active learning course focused on design thinking in health and health care embraced the challenge. Lessons learned, mistakes made, and thoughts on the future of online education in nursing are discussed.

Method:

During the online transition, it was thought the flipped-classroom approach would transition well using the same design thinking methodology taught in the course. Because the course promoted rapid innovation and iteration, such a challenge served as a call to action, and the course became a valuable real-time case study.

Results:

Based on student surveys, the overall quality of the transitioned course increased slightly compared with the previous semester's in-person course, indicating schools of nursing can innovate both the way students are taught as well as what students are taught.

Conclusion:

Rather than mourn the loss of in-person learning, the newfound possibilities of virtual education should celebrated.

Inference for Iterated GMM Under Misspecification
Authors: Hansen Bruce E. , Lee Seojeong
Published: May 2021

This paper develops inference methods for the iterated overidentified Generalized Method of Moments (GMM) estimator. We provide conditions for the existence of the iterated estimator and an asymptotic distribution theory, which allows for mild misspecification. Moment misspecification causes bias in conventional GMM variance estimators, which can lead to severely oversized hypothesis tests. We show how to consistently estimate the correct asymptotic variance matrix. Our simulation results show that our methods are properly sized under both correct specification and mild to moderate misspecification. We illustrate the method with an application to the model of Acemoglu, Johnson, Robinson, and Yared (2008).
Screening in Vertical Oligopolies
Authors: Chade Hector , Swinkels Jeroen
Published: May 2021

A finite number of vertically differentiated firms simultaneously compete for and screen agents with private information about their payoffs. In equilibrium, higher firms serve higher types. Each firm distorts the allocation downward from the efficient level on types below a threshold, but upward above. While payoffs in this game are neither quasi‐concave nor continuous, if firms are sufficiently differentiated, then any strategy profile that satisfies a simple set of necessary conditions is a pure‐stategy equilibrium, and an equilibrium exists. A mixed‐strategy equilibrium exists even when firms are less differentiated. The welfare effects of private information are drastically different than under monopoly. The equilibrium approaches the competitive limit quickly as entry costs grow small. We solve the problem of a multi‐plant firm facing a type‐dependent outside option and use this to study the effect of mergers.
Random ambiguity
Authors: Lu Jay
Published: May 2021

We introduce a model of random ambiguity aversion. Choice is stochastic due to unobserved shocks to both information and ambiguity aversion. This is modeled as a random set of beliefs in the maxmin expected utility model of Gilboa and Schmeidler (1989). We characterize the model and show that the distribution of ambiguity aversion can be uniquely identified from binary choices. A novel stochastic order on random sets is introduced that characterizes greater uncertainty aversion under stochastic choice. If the set of priors is the Aumann expectation of the random set, then choices satisfy dynamic consistency. This corresponds to an agent who knows the distribution of signals but is uncertain about how to interpret signal realizations. More broadly, the analysis of stochastic properties of random ambiguity attitudes provides a theoretical foundation for the study of other random nonlinear utility models.
Delegating learning
Authors: Escobar Juan F. , Zhang Qiaoxi
Published: May 2021

Learning is crucial to organizational decision making but often needs to be delegated. We examine a dynamic delegation problem where a principal decides on a project with uncertain profitability. A biased agent, who is initially as uninformed as the principal, privately learns the profitability over time and communicates to the principal. We formulate learning delegation as a dynamic mechanism design problem and characterize the optimal delegation scheme. We show that private learning gives rise to the trade‐off between how much information to acquire and how promptly it is reflected in the decision. We discuss implications on learning delegation for distinct organizations.
Moč odsotnega: eluzivnost resničnosti v dveh Antigonah
Authors: Senegačnik Brane
Published: May 2021

Kot je dobro znano, bogovi v Sofoklovi Antigoni ne nastopijo (niti prek prerokb), vendar se vse v drami zgodi zaradi njih. Njihova avtoriteta ni sporna, a je prav zato, ker so odsotni, nejasna in eluzivna njihova volja: to odpira prostor Antigoni in Kreontu, da jo razlagata na povsem drugačen način, kar sproži njun usodni konflikt. Ko Tejrezias razkrije, da Kreont nima prav, je že prepozno za Antigono, ki je umrla zato, ker je ostala zvesta svojemu (pravilnemu) razumevanju božje volje (postave), čeprav je v tem ni podpirala nobena zunanja avtoriteta, ne božanska, ne človeška. V Antigoni Dominika Smoleta pa je odsotna naslovna junakinja, in to vse do konca drame, ko jo ubijejo in njeno vlogo prevzame Paž. Smoletova radikalna inovacija nenehoma usmerja pozornost bralca (gledalca) v ozadje dramskega dogajanja, v nevidno resničnost onstran odra: v prepovedano območje izven uradne družbe, kjer se postavljajo bistvena vprašanja o zgodovinski resnici in o tem, kaj človek v resnici je. Drami kažeta analogne poteze v dramaturški zgradbi, zlasti pa v predstavljanju resničnosti: ultimativna resničnost (bogovi pri Sofoklu, človekova resnična identiteta) je v obeh prikrita, vendar bistveno učinkuje na življenje: razkriva se kot temno obzorje in ohranja človeško resničnost odprto. Poleg glavne teme razprava razmeroma nadrobno obravnava tudi motive za (literarno in teoretično) reinterpretacijo kanoniziranih besedil.
Literatura je neskončna zakladnica edinstvenih situacij. Tomo Virk, dobitnik Priznanja Antona Ocvirka 2020
Authors: Virk Tomo , Kocijančič Matic
Published: May 2021

Tomo Virk – prejemnik priznanja Antona Ocvirka za najboljšo izvirno komparativistično monografijo zadnjih dveh let, ki ga je Slovensko društvo za primerjalno književnost lani podelilo tretjič – je eden izmed vodilnih slovenskih literarnih teoretikov in zgodovinarjev, pa tudi esejist, prevajalec in redni profesor na Oddelku za primerjalno književnost in literarno teorijo Filozofske fakultete Univerze v Ljubljani. Njegove prve monografije – npr. Duhovno zgodovino (1989) in Kratko zgodovino večnosti (1993) – zaznamuje svojevrsten preplet literarnih, filozofskih in religioznih vprašanj. Posebej intenzivno se je ukvarjal s postmodernizmom v (tuji in slovenski) literaturi, mdr. že v doktorski disertaciji, v kateri je obravnaval »usodo slovenskega romana v dobi postmodernizma«. V eni od svojih najodmevnejših monografij iz devetdesetih, Beli dami v labirintu (1994) – zanjo je prejel nagrado zlata ptica –, je tematiziral »idejni svet J. L. Borgesa«. V kontekstu slovenske literarne in idejne zgodovine pa je še posebej natančno preučeval Bartola in Juga. Že v devetdesetih se je uveljavil kot eden največjih slovenskih poznavalcev metodologije literarnih ved. Leta 2007 je izšlo eno izmed njegovih najambicioznejših del, Primerjalna književnost na prelomu tisočletja, v katerem je predstavil in ovrednotil temeljne smernice sodobne svetovne in slovenske primerjalne književnosti ter obenem podal svojo vizijo njene prihodnosti. Za svoje delo je prejel številne nagrade in priznanja, mdr. nagrado Marjana Rožanca za Ujetnike bolečine (1995) in zlati znak ZRC SAZU za znanstveno monografijo Strah pred naivnostjo: poetika postmodernistične proze (2000). – Komisija priznanja Antona Ocvirka za leto 2020, ki so jo sestavljali Anja Mrak, Marcello Potocco in Igor Žunkovič (predsednik), je v obrazložitvi svoje odločitve, da nagrado podeli Virkovi monografiji Etični obrat v literarni vedi (2018), zapisala: »Gre za prvo slovensko znanstveno monografijo, ki obravnava enega od pomembnejših pojavov v literarni vedi ob koncu tisočletja, to je zvezo med literaturo in etiko. […] Etični obrat v literarni vedi je napisan jasno, natančno in premišljeno, obenem pa z velikim občutkom za jezik in bralca. Virk nam z značilno duhovitostjo nazorno posreduje literarno teoretske probleme, ki se v besedilih številnih drugih avtorjev zdijo nedoumljiva zagonetka. Prav zato gre za besedilo, ki je ob strokovni dostopno še širši javnosti, s čimer prispeva k najsodobnejšim premislekom o etiki tudi onstran literature in literarne vede, s tem pa nenazadnje k pomenu in ugledu primerjalne književnosti na Slovenskem ter slovenske literarne vede v svetu.« – S Tomom Virkom sva se pogovarjala na slavnostnem dogodku SDPK ob podelitvi nagrade, 7. oktobra 2020 v Prešernovi dvorani SAZU.
Effective Communication Approaches for Decision Analytics
Authors: Reboulet Amanda , Jackson Ross A.
Published: May 2021

Analysts ignore the context that shapes and constrains communication at their peril. The rhetorical context in which analytics is enacted influences the communicative approach. In this chapter, two dominate elements are considered: 1) analytic complexity and 2) rhetorical context. Along this analytic-rhetorical spectrum, a four-square matrix is developed using these elements to describe distinct environments in which analytics is enacted. While each of the four positions are addressed for inclusion in this chapter, the focus is narrowed to an exposition of strategies for effectively communicating insights within the realm of decision analytics. Marked by a more basic analytic framework, decision analytics aims to support successful consumption and utilization at senior levels of organizations. Decision analytics differ from other types of analytics since they support the process of making decisions versus providing information. This chapter focuses on how analysts can use decision analytics to effectively communicate analytic results and insights to senior leaders of organizations.
Neuroeconomics as a Factor in the Decision-Making of Women Entrepreneurs in Developing Countries
Authors: Cervantes-Guzmán Jovanna Nathalie
Published: May 2021

Neuroeconomics will help solve questions that constitute a good decision, the factors that influence decisions, and how they are made. The study will expose from the experts' opinion the tangible and intangible factors that influence decisions from the perspective of the neuroeconomics. A modified Dephi method that integrates neuroeconomics is used. Neuroeconomics has the potential to explain phenomena that are considered a deviation from the prediction or behavioral bias of decision-making models in economic theory. The study exposes the opinions that have a greater degree of relevance from the experts.
Communicating Conscious Business Practice at an Ecologically-Conscious Architectural Studio
Authors: Pattnaik Pinaki Nandan , Shukla Mahendra Kumar
Published: May 2021

This chapter presents an exploratory case study of how Mr. Zero, a pencil developed by the Ecologically Conscious Architectural Studio (ECAS) at Auroville, India integrates product micro-culture and the concept of conscious business in deriving sustainable practices with an aim of achieving a sustainable future. Through this chapter, the authors make an attempt at developing a deeper understanding of the concept of conscious business and its importance. Finally, the authors, through a qualitative analysis of a case study of Mr. Zero, map the practice of connecting conscious business movement through the adoption of product micro-culture at ECAS to evaluate its applicability in modern day business. At the end, the authors record findings on the interplay between product micro-culture and the conscious business movement for adoption by other businesses or even adaptation by others depending upon the context for viable sustainable solutions.
