Simulating low-frequency wind fluctuations
Authors: Syed Abdul Haseeb , Mann Jakob 
Published: October 2023

Abstract. Large-scale flow structures are vital in influencing the dynamic response of floating wind turbines and wake meandering behind large offshore wind turbines. It is imperative that we develop an inflow wind turbulence model capable of replicating the large-scale and low-frequency wind fluctuations occurring in the marine atmosphere since the current turbulence models do not account well for this phenomenon. Here, we present a method to simulate low-frequency wind fluctuations. This method employs the two-dimensional spectral tensor for low-frequency, anisotropic wind fluctuations presented by Syed and Mann (2023) to generate stochastic wind fields. The simulation method generates large-scale 2D wind fields for the longitudinal u and lateral v wind components. The low-frequency wind turbulence is assumed to be independent of the high-frequency turbulence thus a broad spectral representation can be obtained just by superposing the two turbulent wind fields. The method is tested by comparing the simulated and theoretical spectra and co-coherences of the combined low- and high-frequency fluctuations. Furthermore, the low-frequency wind fluctuations can also be subjected to anisotropy. The resulting wind fields from this method can be used to analyze the impact of low-frequency wind fluctuations on wind turbine loads and dynamic response and for studying the wake meandering behind large offshore wind farms.

Authors: Putra Aditya , Fathurrahman Reza 
Published: October 2023

Purpose: This research aims to enhance the quality of online tax services in Indonesia by identifying and addressing service-related issues, offering practical solutions, and paving the way for future research endeavors that can further refine and optimize digital governance in the tax domain.

Theoretical Reference: This study draws upon theoretical frameworks related to service quality assessment and evaluation in the context of online government services. By integrating these theoretical perspectives, this research seeks to analyze online tax service quality in Indonesia comprehensively and offer practical solutions to address the identified issues.

Method: Various researchers studied service quality, from manual to electronic service, and different countries. However, almost all of them used a quantitative approach, which sometimes cannot explain the reason behind events. For these reasons, this research chose a qualitative approach to evaluate online tax service quality owned by the Directorate General of Taxes by observing, documenting, and interviewing. The interviewees were taxpayers and the Directorate General of Taxes’ employees, connecting both views.

Results and Discussion: It turns out that the current service, in general, can fulfill taxpayers’ needs to a certain degree, and the taxpayers are satisfied. This research also addressed several problems related to the online tax service, such as server capability, internal communication, understaffing, and ICT infrastructure problems.

Implications of Research: The findings of this research hold significant implications for policymakers and practitioners in the field of online tax services in Indonesia.

Originality/value: This research contributes to the tax field by presenting solutions related to the problems of tax service quality. This study contributes to the existing body of knowledge in online tax services and e-government in several distinctive ways, adding originality and value to the academic and practical discourse.

Conclusion: The current online tax service quality is generally sufficient to satisfy taxpayers. The problems that cause some taxpayers to feel dissatisfied or complain are prominently directed to the server capacity, human resources, the DGT’s internal communication, and the digital divide.
Extracorporeal cardiopulmonary resuscitation for refractory cardiac arrest in Australia: a narrative review
Authors: Dennis Mark , Shekar Kiran , Burrell Aidan JC ,   For the National ECPR Working Group
Published: October 2023

Summary

Extracorporeal cardiopulmonary resuscitation (ECPR) in patients with prolonged or refractory out‐of‐hospital cardiac arrest (OHCA) is likely to be beneficial when used as part of a well developed emergency service system.

ECPR is technically challenging to initiate and resource‐intensive, but it has been found to be cost‐effective in hospital‐based ECPR programs.

ECPR expansion within Australia has thus far been reactive and does not provide broad coverage or equity of access for patients.

Newer delivery strategies that improve access to ECPR for patients with OHCA are being trialled, including networked hospital‐based ECPR and pre‐hospital ECPR programs. The efficacy, scalability, sustainability and cost‐effectiveness of these programs need to be assessed.

There is a need for national collaboration to determine the most cost‐effective delivery strategies for ECPR provision along with its place in the OHCA survival chain.

Published: October 2023

AbstractIntroductionDiabetes‐related foot disease (DFD) — foot ulcers, infection, ischaemia — is a leading cause of hospitalisation, disability, and health care costs in Australia. The previous 2011 Australian guideline for DFD was outdated. We developed new Australian evidence‐based guidelines for DFD by systematically adapting suitable international guidelines to the Australian context using the ADAPTE and GRADE approaches recommended by the NHMRC.Main recommendationsThis article summarises the most relevant of the 98 recommendations made across six new guidelines for the general medical audience, including:

prevention — screening, education, self‐care, footwear, and treatments to prevent DFD;
classification — classifications systems for ulcers, infection, ischaemia and auditing;
peripheral artery disease (PAD) — examinations and imaging for diagnosis, severity classification, and treatments;
infection — examinations, cultures, imaging and inflammatory markers for diagnosis, severity classification, and treatments;
offloading — pressure offloading treatments for different ulcer types and locations; and
wound healing — debridement, wound dressing selection principles and wound treatments for non‐healing ulcers.
Changes in management as a result of the guidelineFor people without DFD, key changes include using a new risk stratification system for screening, categorising risk and managing people at increased risk of DFD. For those categorised at increased risk of DFD, more specific self‐monitoring, footwear prescription, surgical treatments, and activity management practices to prevent DFD have been recommended. For people with DFD, key changes include using new ulcer, infection and PAD classification systems for assessing, documenting and communicating DFD severity. These systems also inform more specific PAD, infection, pressure offloading, and wound healing management recommendations to resolve DFD.
Dynamic Response Mechanism and Prediction Model of Fractured Formation Loss

Published: October 2023

ABSTRACT
The deep fractured formation has the characteristics of complicated temperature and pressure environment and narrow safe density window, which makes it easy to lose during drilling. Most of the loss models established in the past only start from the perspective of mudflow and ignore the coupling between fluid and surrounding rock, which makes their application unsatisfactory. To better understand the dynamic response mechanism of fractured loss in the formation, and obtain the changes of fluid and formation in this process. A new model is developed to simulate the loss of drilling fluid, predict the total loss and the mud penetration distance, based on the stress-seepage coupling method of dual-porosity media and the non-Newtonian fluid seepage law. Using this model, the whole process of the loss is analyzed. It is found that the flow rate is rapid at first and then slow, and the total loss increases continuously. At the same time, the influence law of various parameters related to the formation and mud on the loss is studied. The results show that the bottom pressure, mud rheology, and initial width of fracture have significant effects on total loss. Among them, the total loss increases with the increase of bottom pressure and initial fracture width, and decreases with the increase of mud viscosity. The change of elastic modulus and Poisson's ratio has little effect on the total loss.
Optimal control applied to a visceral leishmaniasis model
Authors: Pantha Buddhi , Agusto Folashade B. , Elmojtaba Ibrahim M. 
Published: October 2023

In this article, we developed a deterministic model for the transmission dynamics of visceral leishmaniasis in humans, canine reservoirs and sandflies, which is the only vector that transmits the disease parasite. The theoretical and epidemiological findings of this study indicates that the disease-free equilibrium of the model is locally and globally asymptotically stable when the associated reproduction number is less than unity. We perform sensitivity analysis on the model parameter to determine the parameter with the most impact on the reproduction number. Following the results obtained from the sensitivity analysis, we apply optimal control theory using three time dependent control variables representing personal protection, insecticide spraying and culling of infected canine reservoirs. Simulation results are presented for various outbreak scenarios which indicates that leishmaniasis can be eliminated from a region by the application of three time dependent controls representing respectively, personal protection, insecticide spraying and culling infected canine reservoir.

Medindo o impacto regional da política monetária brasileira: uma comparação entre as Regiões Nordeste e Sul
Authors: Araújo Eurilton 
Published: October 2023

Este trabalho procura documentar o impacto da política monetária brasileira após o Plano Realnas regiões Nordeste e Sul, usando vetores autoregressivos (VAR). Procura-se avaliar quantitativamente o grau de assimetria em termos das respostas dos índices de produção industrial das respectivas regiões a um choque de política monetária. Constata-se que as respostas ao impulso associadas ao choque de política monetária para as duas regiões em termos agregados são bastante assimétricas. O Sul tende a reagir mais fortemente ao choque que oNordeste. O impacto em nível estadual é também bastante assimétrico. Apesar dos estados do Sul serem mais afetados pelo choque de política monetária relativamente aos Estados nordestinos, Bahia e Pernambuco reagem fortemente ao choque em comparação com o Nordeste como um todo.
Saldos Migratórios: Uma Análise por Estados e Regiões do Brasil (1986-2006)
Authors: De Queiroz Silvana Nunes , Dos Santos José Márcio 
Published: October 2023

A partir dos anos 1950, houve no Brasil a caracterização de regiões de origem/expulsão de migrantes, como o Nordeste brasileiro e o Estado de Minas Gerais, e regiões de destino/atração, como o Sudeste, em especial o Estado de São Paulo. Tais fluxos vêm apresentando mudanças significativas. O presente artigo examina as recentes mudanças na dinâmica migratória interna brasileira, embasando teoricamente os possíveis determinantes que corroborem estes resultados. Usa como base de dados os Censos Demográficos de 1991 e 2000 e a Pesquisa Nacional por Amostra de Domicílios (PNAD) de 2001 a 2006. Observa que, durante a década de 1990, ocorreram poucas mudanças nos saldos migratórios, com a manutenção dos fluxos migratórios observados na década de 1980. Todavia, os primeiros anos do século XXI apresentam importantes reversões nos recentes saldos migratórios internos em algumas regiões e estados brasileiros.
Gastos Públicos Municipais e Educação Fundamental na Paraíba: Uma Avaliação usando DEA
Authors: De Almeida Aléssio Tony Cavalcanti , Gasparini Carlos Eduardo 
Published: October 2023

Parte da constatação de que o esforço de universalização do ensino fundamental no Brasil foi seguido por sérios questionamentos sobre a qualidade dos serviços prestados. E que, apesar da oportunidade e da importância de se debater o tema, seja pela relevância da educação, seja pela preocupação com a eficiência pública, as discussões ainda carecem de indicadores objetivos que permitam avaliar concretamente a situação. Nesse contexto, o artigo propõe um índice de eficiência e qualidade dos gastos públicos em educação e o aplica para os municípios do Estado da Paraíba. Para tanto, usa a metodologia Data Envelopment Analysis (DEA), com o intuito de verificar quais as cidades mais e menos eficientes na oferta do serviço educacional. Os resultados permitem concluir que os municípios menores são os que apresentam pior situação e que os grandes centros do Estado aparentam influenciar positivamente a performance dos vizinhos.
Fatores determinantes da alocação de tempo em trabalho não-agrícola por famílias do projeto Dom Helder Câmara
Authors: De Mesquita Shirley Pereira , Sampaio Luciano Menezes Bezerra , Ramalho Hilton Martins de Brito 
Published: October 2023

Analisa as variáveis que influenciam a alocação de trabalho não-agrícola de famílias rurais do Nordeste brasileiro. Utiliza duas estratégias empíricas: um modelo double hurdle que permite a estimação conjunta das decisões de participação no mercado de trabalho não-agrícola e da quantidade de horas alocadas neste e, de modo alternativo, para estas mesmas duas decisões, estimativas separadas pelos modelos probit e tobit, respectivamente. Os resultados apontaram que algumas variáveis, destacando gênero, apresentam efeitos contrários para a decisão de participação e de quantidade de horas trabalhadas, pelo modelo double hurdle, o que não é possível captar quando se recorre aos outros dois modelos citados e mais comumente usados na literatura. Os resultados destacam, ainda, a importância de características individuais, tais como idade, anos de estudo e estrutura familiar (número de crianças) nas decisões de trabalho não-agrícola dos membros de famílias rurais.
Economia agrícola, instituições e desenvolvimento rural: uma análise comparativa da diversificação econômica do pólo Assu/Mossoró (RN)
Authors: Nunes Emanoel Márcio , Schneider Sergio 
Published: October 2023

Este trabalho visa analisar a economia agrícola e o desenvolvimento rural através da comparação da diversidade econômica de três dinâmicas regionais do Polo Assu-Mossoró, Rio Grande do Norte (RN). Para isso, mostra resultados (econômicos e não-econômicos) a partir de escolhas e estratégias dos agricultores familiares no nível local e das formas como estes obtêm e utilizam recursos disponíveis e compartilham mercados. A metodologia consistiu da comparação das dinâmicas regionais utilizando os princípios da economia institucional para interpretar a mercantilização e os estilos de agricultura, a partir de uma pesquisa realizada com 271 famílias de agricultores de Alto do Rodrigues, Baraúna e Serra do Mel. A hipótese é de que a dinâmica que escolheu o caminho da modernização se caracterizou como de elevada mercantilização e estilos de agricultura especializados e dependentes. E a que escolheu o afastamento gradual do mercado se tornou, no tempo, mais autônoma e menos vulnerável a influências externas. Na busca de um desenvolvimento relativamente autônomo e mediado por instituições, conclui que a análise a que se propõe este artigo torna-se relevante para a busca de um olhar diferente para o debate atual em torno do desenvolvimento do Nordeste.

Published: October 2023

Constata que as transformações ocorridas a partir da década de 1980 contribuíram para a redução na oferta de empregos e para o aumento dos níveis de exigências com os trabalhadores. Nesse cenário, os jovens e as mulheres foram os mais afetados. Tem por objetivo identificar e analisar os determinantes da inserção de mulheres jovens, entre 15 e 24 anos, no mercado de trabalho nordestino. Para isso, utiliza a Pesquisa Nacional por Amostra de Domicílios (PNAD) referente ao ano de 2009 e procede à estimação de um modelo multinomial logit, considerando-se três possíveis categorias em que as jovens poderiam se enquadrar: inativa, ativa e empregada e ativa e desempregada. Os resultados indicam que os fatores mais relevantes na inserção das jovens na categoria ativa e empregada foram experiência, escolaridade, renda e existência de filho.
