The Impact of International Trade on Central Bank Efficiency: An Application of DEA and Tobit Regression Analysis
Authors: Dar Qaiser Farooq , Ahn Young-Hyo , Dar Gulbadin Farooq 
Published: March 2021

The purpose of this study is to introduce a novel methodology to measure the central bank efficiency. The data envelopment analysis (DEA) applies in the combination of three input and two output variables characterizing the economic balance in international trade. Super-efficiency DEA model is applied for ranking & comparing the efficiency of different central banks. In contrast, the Malmquist productivity index (MPI) is used to measure the productivity change over the period of time. Further, the study is extended to quantify the impact of international trade dimension on the efficiency of the central bank by using Tobit regression analysis. Finally, based on our data analysis, we reported that the efficiency changes over the period of time and the total productivity changes significantly due to the technology shift as compared to efficiency change. Additionally, it is also observed that the central bank efficiency is impacted dramatically by the export level of the country as compared to import level, average exchange rate and GDP. It implies that the export level of the country significantly influences the performances of the central bank.

Published: March 2021

A flexible ranked set sampling scheme including some various existing sampling methods is proposed. This scheme may be used to minimize the error of ranking and the cost of sampling. Based on the data obtained from this scheme, the maximum likelihood estimation as well as the Fisher information are studied for the scale family of distributions. The existence and uniqueness of the maximum likelihood estimator of the scale parameter of the exponential and normal distributions are investigated. Moreover, the optimal scheme is derived via simulation and numerical computations.

Published: March 2021

This study aimed to validate the use of UAV-based point cloud analysis to detect canopy decline severity and its spatial distribution in vineyards.A new approach to assess canopy decline, caused by Eutypa dieback-like symptoms, using unmanned aerial vehicle (UAV) remote sensing was compared with ground visual assessment in the vineyard. Canopy point cloud captured by UAV-based imagery during the growing season was analysed by a customized program to determine canopy decline severity and spatial distribution in a symptomatic Shiraz vineyard in Eden Valley, South Australia. Experienced assessors performed a ground visual assessment in the vineyard at E-L stage 15. k-means clustering was used to detect reduced canopy volume due to Eutypa dieback-like symptoms. Results from point cloud analysis showed that 12.5 % of the total canopy length in the vineyard had Eutypa dieback symptoms while the ground visual assessment detected 11.4 %. Confusion matrix results showed an accuracy of 87.4 % and a kappa coefficient of 0.43 compared with ground visual assessments. Additionally, automatic analysis of the point cloud was quicker than the ground visual assessment and generated precise geographic coordinates of the symptomatic canopy sections. Point cloud analysis can detect Eutypa dieback-like symptoms and its spatial distribution with 87.4 % accuracy, compared with the ground assessment. Similar to ground visual assessment, E-L stage 15 appears to be a suitable stage to apply point cloud analysis to make Eutypa dieback-like symptom assessments. Grapevine canopy decline, caused by various factors such as Eutypa dieback and inadequate management, can cause yield reduction and threaten vineyard longevity. Compared with tedious ground visual assessments, point cloud analysis can accelerate the assessment of canopy decline in vineyards and help with the planning of remedial practices using precise geographic coordinates of the affected sections.

RESUMO
A pandemia do COVID-19 é considerada a principal ameaça à saúde e o bem-estar de todos, a nível global, criando danos psicológicos, sociais e econômicos. Os países africanos têm sistemas de saúde frágeis, por este motivo, a África deve enfrentar a pandemia do COVID-19 como uma guerra a ser vencida e estar preparada para aumentar significativamente os gastos em saúde pública, criando uma cooperação múltipla que abrange todos os sectores essenciais. Esta pesquisa teve como objetivo analisar os desafios enfrentados na implementação das medidas de prevenção adotadas pelos três (3) países africanos mais afetados pelo COVID-19, nomeadamente África do Sul, Argélia e Nigéria. Para a realização desta revisão bibliográfica, foi necessário fazer buscas nas bases de dados Medline, Embase, SCIELO e outros recursos relevantes para elaboração do artigo. Nesta pesquisa, constatou-se que em alguns países Africanos, mesmo com as medidas de bloqueio impostas pelos governos locais para impedir a disseminação do vírus, trabalhadores informais vão as ruas praticar o comércio, situação que os colocam em risco de infecção pelo novo Coronavírus. Assim, torna-se imprescindível o governo criar auxílio emergencial ou disponibilizar cesta básica para os mais necessitados, evitando o descumprimento das diretivas estritas para combater a propagação do COVID-19.

Imagining Outside of a Pandemic
Authors: Gareiss Nic 
Published: March 2021

I'm a dancer who engages improvisation every time I put on my shoes to brush, step, click, and knock the floor. Not surprisingly, my work until March 2020 was primarily with fellow sound-makers, usually folk musicians from Ireland, Scotland, what's now called Canada, and what's now called Appalachia. COVID-19 has forced me to listen to the extemporaneous music I make anew, in the absence of collaborators, within a soundscape of profound uncertainty. In this contribution, I offer a voice from the floor, enunciated by my lowest limbs contacting the surface upon which I stand. This is where my work as an LGBTQ2IA+ improvising step dancer finds its meaning. In this essay, I respond to the incisive queer horizon Thomas F. DeFrantz casts, as "imagining outside of what came before." I share ways I have been thinking about improvisation and offer thoughts on how we might learn from DeFrantz to imagine and improvise “outside of” critically, queerly, and generatively.

Comparison of the seismic and wind analyses of two tower cranes
Authors: Oliveira Carlos S. , Correia Pedro M. B. 
Published: March 2021

Tower cranes act as essential support equipment for the development of the city’s construction projects, not only for new projects but also in the rehabilitation of old structures. In the present study, we analyze and compare two different tower cranes, where the differences are essentially based on the geometry, weight, and consequently the reach and load capacity of each structure. In general, these types of structures correspond to slender steel structures designed to carry high loads. Despite the great importance given to these structures, many disasters have occurred causing damage to people or to urban equipment in the vicinity due to total or partial collapse. We developed a 3-D mathematical linear model of the structures in SAP2000 and compared the analytical frequencies with in situ measurements. The maximum error for the first two translationally identified modes in the x and y directions was 4.9 %. These structures are very flexible, with frequencies below 0.5 Hz. We then applied and evaluated the impact of two types of exceptional action, seismic (maximum reference acceleration of 1.5 m/s2 and 1.7 m/s2) and wind load characteristics of an urban area (surrounded by buildings), for the two structures not carrying any load. The effects resulted in no serious consequences, with wind being the most severe action in certain cross-sections and seismic action in others. One very important and innovative aspect of this study was the in situ characterization of the frequencies and the verification that the mathematical model reproduced the behavior of the real structure very well. We complemented this study by measuring four more structures and proposing a law to estimate the frequency as a function of the length of the tower plus jib. However, we also found from a literature review of recently published work that, contrary to the six structures that we analyzed, it is difficult to extrapolate this law for other types of tower cranes.

Published: March 2021

In a manufacturing company, the quality loss is estimated by considering the number of defects. Taguchi is a method that finds strong conditions in uncontrollable environments of the field. Taguchi quantifies quality loss through a quality loss function. The Taguchi method particularly is focused on industrial processes. The method is actualizing quality philosophy for continuous quality improvement and cost reduction to improve manufacturing performance. The analysis is designed using Taguchi technique which is related to quality. A high-quality product has a minimal defect. The Taguchi method is used to analyze several defects of ammunition to reduce the number of ammunition defects. Ammunition consists of several parts are called projectile or bullet, cartridge case, propellant charge, and primer. Every part of its process possibly contributes to any defect. The defect type in every part of ammunition consists of critical, major, and minor defects. This paper is focused on cartridge case caliber 5.56 mm defect by using the Taguchi method. The <span lang="EN-ID">quality characteristic of the experiment result used is smaller the better</span><span lang="EN-ID">. </span>Critical to Quality (CTQ) is determined to get a critical defect for cartridge cases such as split and perforated case. The influencing factors are brass cup thickness, hardness case after annealing, and annealing temperature.

Published: March 2021

<span lang="EN-ID">The result of a turning process is strongly influenced by the process parameters that could result in the product to be unacceptable. The cutting parameters may be determined according to the material hardness and roughness of the workpiece surface. The purpose of this paper is to investigate the effects of cutting speed and feed rate on surface roughness and vibration. In Taguchi method, the number of experiments is reduced by orthogonal arrays while the effects of uncontrollable factors are also also reduced. The Taguchi method is used to reduce track, experimental time and production cost. Simple and precise are the most benefits of this method. Unstable vibrations in machining operations, known as chats, can cause damage to tools, workpieces, and machine tools. Cutting force is found to be the most dominant factor affecting surface roughness.</span>
Piskan ställningen
Authors: Livia Prawitz  
Published: March 2021

The courtyard, laundry room, and areas for beating carpets are collective facilities in the private sphere of the home. In Stockholm you can find carpet hangers in connection to many apartment blocks even though they are very seldom used nowadays. The act of whipping carpets is an act that aims to get rid of the dirt – the remnants of life. Cleaning is a repetitive work, where something needs to be done over and over again without it producing something new.

The project Piskan ställningen consists of an essay, sound pieces, and sketches in different materials and is divided into three parts; the one who beats, the beater itself, and that which constitutes a stand for the beating. The various associations to the carpet hanger and the carpet beater form the basis of the project that centres around questions concerning repetition and productivity, place and time, the boundary between the public and the domestic sphere, and how dangerous the pursuit of alleged purity, hygiene, science, and light can be. Through text, sound and images, personal and collective memories, and the object's associations regarding reproductive labour, city planning, violence, the welfare project, and childish games are intertwined.

The material also contains other associations to control and power – with the whip as a means of threat and punishment, and an exploration of different forms of emptiness in relation to architecture, social structures, and mental space. Through a younger and an elderly woman's narrative voice, we follow an associative thought chain that interweaves the public, the domestic, and a bodily sphere. The setting is a society where she comes home from work to yet another form of monotonous routines, where cars get burned down, and tables are placed under vases, whilst someone has been digging a hole down in the city.

Through sketches in different materials, I approach the carpet beater by exploring its shape. My attempts to repeat the knots lead to a series of variations on the memory of whips where mistakes constitute the basis of new forms. In the project repetition and variations in sound, text, and drawing becomes another way of approaching repetitive work
