Authors: Sun Nam Park Sun Nam Park , Hyeran An Hyeran An , Jongeun Lee Jongeun Lee ,   Crisis and Emergency Management: Theory and Praxis
Published: November 2021

This study is a descriptive research conducted to identify the factors affecting the incivility experiences of nursing students in clinical practice. A total of 195 juniors and senior nursing students were selected between September and November 2018 from the nursing department of two universities in Seoul and Chungbuk. Data were collected using K-SSRS, MSFAS, KEES, and K-UBCNE Scale. The results showed that the incivility scores experienced by nursing college students were 2.10 ± 0.82 points out of 5. There was a positive correlation between self-absorption and incivility and a negative correlation between activity, a sub-factor of emotional expressivity, and incivility. Factors influencing incivility experiences were grades, clinical practice period, satisfaction with clinical practice education, activity, and self–absorption, which is a sub-factor of maladaptive self–focused attention. Furthermore, the explanatory power of the factors’ incivility was 17.9%. Based on the results of this study, future research should aim to develop a training program to help nursing students positively cope with incivility during clinical practice.

Working processes in the technological sewing process are performed on machine systems characterized by machine-manual work, where the worker and the machine work simultaneously. Such a work system requires a great deal of responsibility in terms of quality, quantity, and the accurate and timely execution of tasks, which requires the quick and accurate response and extremely good psychomotor and visual skills of workers. This paper presents the process of determining the working method and normal times for the technological operation of runstitching women’s blouse collars, which includes the design of an ergonomically designed workplace, the selection and technical equipment of the universal sewing machine and the determination of the optimal work method and normal times using the Methods-Time Measurement (MTM) system. The research results obtained indicate that the technical equipment of a universal sewing machine has a significant impact on the structure of the technological sewing operation and the working method, i.e. the number of auxiliary manual technological suboperations. Improving technical equipment, i.e. increasing the number of automated functions used on a universal sewing machine, reduces the number of auxiliary manual suboperations, reduces the time required to perform the technological operation and increases work productivity.

Queer Masculinities: Gender Roles, the Abject and Bottomhood in Ocean Vuong’sOn Earth We’re Briefly Gorgeous
Authors: Slopek Christina
Published: November 2021

This article analyzes queerness in Ocean Vuong’sOn Earth We’re Briefly Gorgeous(2019), teasing out how the queer relationship at the core of the novel is framed. Ocean Vuong’s novel mobilizes queerness to straddle boundaries between cultures, gender roles and bodies.On Earth We’re Briefly Gorgeousplaces the queer sexual orientations and gender performances of its protagonists, one Vietnamese American, one white American, in firm relation to the formative force of cultural contexts. Zooming in on two young boys’ queerness, the novel diversifies gender roles and makes room especially for non-normative masculinities. What is more,On Earth We’re Briefly Gorgeousmobilizes the abject to showcase how queer sexual intimacy straddles boundaries between bodies and subjects. The article attends to language politics in connection with the novel’s coming-out performance, striated constructions of gender roles and their interplay with the abject and “bottomhood” (Nguyen 2014: 2) to come to grips with the novel’s diversification of queer masculinities.
An improved Wilson equation for phase equilibrium K values estimation
Authors: Monnery Wayne D.
Published: November 2021

Phase equilibrium K values are either estimated with empirical correlations or rigorously calculated based on fugacity values determined from an equation of state. There have been several empirical analytical equations such as Raoult’s Law, the Hoffman Equations (Hoffman A, Crump J, Hocott C. Equilibrium constants for a gas condensate system. J Petrol Technol 1953;5:1–10) and their modifications and the well-known Wilson Equation (Wilson G. A modified Redlich–Kwong equation of state applicable to general physical data calculations. In: AIChE National Meeting Paper15C, May 4–7, Cleveland, OH; 1969). along with several modifications. This work presents a new modification of the Wilson Equation for estimating phase equilibrium K values, predominantly for light hydrocarbon mixtures. The modification is based on correlating a subset of a database of K values, established from convergence pressure data. Results show the method to accurately correlate and predict the K value data, within 10% on average. Moreover, the predicted K factors provide remarkable results for such a simple model when used in a variety of phase equilibrium calculations. The results also show that the new model compares favorably with existing empirical analytical methods. Such a model would provide excellent initial estimates for rigorous thermodynamic calculations.
Signs, forms, and models: Thomas A. Sebeok’s enduring legacy for semiotics
Authors: Danesi Marcel
Published: November 2021

Thomas A. Sebeok has left semiotics a comprehensive theoretical apparatus for studying semiosis across species and across systems (biological and artificial). Uniting the notions ofform,sign, andmodelinto an integrative purview of meaning-making, known as modeling systems theory, Sebeok has provided a conceptual and terminological apparatus for studying allforms of meaningin terms of the fundamental “standing-for principle” that undergirds all semiotic theories. This essay revisits the Sebeokian perspective, delineating its main components in a retrospective way, highlighting its value not only to semiotics but to computer science as well. Above all else, Sebeok has made it possible concretely to establish specific interconnections between semiotics and cognate disciplines in ways that are relatively free of terminological complexities and ambiguities which have beset semiotics in the past.
Design and simulation of a MEMS MIM capacitive pressure sensor with high sensitivity in low pressure range
Authors: Ansari Hamid Reza , Kordrostami Zoheir
Published: November 2021

In this paper, the improvement of the sensitivity of a capacitive MEMS pressure sensor is investigated. The proposed spring for the sensor can increase the sensitivity. Silicon is used as the substrate and gold and aluminium nitrate are used as the diaphragm and the dielectric layer, respectively. The dimensions of the diaphragm are 150 µm × 150 µm, which is suspended by four springs. The air gap between the diaphragm and the top electrode is 1.5 µm. The proposed structure is an efficient sensor for the pressures in the range of 1–20 kPa. By using the proposed design, the sensitivity of the MEMS sensor in 18 kPa has improved to 663 (× 10−3 pF/kPa).
The change pattern in serum G protein-coupled estrogen receptor-1 (GPER1) levels during pregnancy with and without gestational diabetes mellitus
Authors: Guven Berrak , Akdemir Yesim
Published: November 2021

Objectives

The purpose of this study was to evaluate serum G protein-coupled estrogen receptor-1 (GPER1) levels in non-pregnant and pregnant with and without gestational diabetes mellitus (GDM).

Methods

The study comprised 40 pregnant women with (n=20) and without GDM (n=20) and 20 healthy non-pregnant women. Data as maternal age, gestational age, and body mass index (BMI) of participants were recorded and serum samples were collected. Serum GPER1 levels were measured by enzyme-linked immunosorbent assays.

Results

Serum GPER1 level was significantly higher in GDM (p=0.03) and non-pregnant women (p=0.005) than those of normal pregnancy. There was no significant correlation between the serum GPER1 levels age (r=0.18, p=0.34), gestational age (r=−0.22, p=0.47), and BMI (r=0.004, p=0.975).

Conclusions

Our results suggest that changes in serum GPER1 levels in pregnancy and GDM may be associated with estrogen. More detailed studies should be conducted to monitor the changes and their interactions in serum sex hormones and serum GPER1 levels during GDM.
Pentimenti. Cartografías peripatéticas que invitan a “recordar lo nuevo”: Una aproximación a la obra poética de Luisa Futoransky
Authors: Page Philippa
Published: November 2021

Este artículo propone una aproximación a la obra de la renombrada poeta argentina Luisa Futoransky (Buenos Aires, 1939) a través de las cartografías afectivas dibujadas por sus versos. Su objetivo es esbozar algunos ejes y algunas capas de este gran mapa textual compuesto a lo largo de su obra, y a la vez proponer, dentro de esa noción de una cartografía afectiva, una estrategia de lectura que se inspira en dos ideas principales. Primero, en leer las derivas en la obra de Futoransky no solo como la representación de múltiples instantes de destierro sino también como un gesto de apertura hacia nuevos caminos. Más específicamente, como la afirmación de undevenir-nómadeen el sentido que le otorga la filósofa Rosi Braidotti (2011). Segundo, el artículo propone una estrategia de lectura que se basa en un fenómeno propio de la pintura que se llamail pentimento. Juntas, estas dos ideas permiten descifrar la ciudad escrita sobre la marcha: la horizontalidad dibujada por los flujos de la deriva y su devenir se cruza con la verticalidad que implica leer la ciudad, no hacia arriba, sino como palimpsesto hacia sus profundidades escondidas e invisibles, desde la óptica delpentimento.
Recycling of Bagasse as an Agricultural Waste and its Effect as Filler on Some Mechanical and Physical Properties of SBR Composites
Authors: Khalaf E. S. A.
Published: November 2021

In the present study, a series of mixes based on different concentrations of carbon black (CB) as a reinforcing filler and sugarcane bagasse as supplementary filler, were investigated to examine their effects on the mechanical properties of styrene butadiene rubber (SBR) composites. To this end, the first group of mixes deals with the effect of different concentrations of CB ranging from 0 to 80 phr at fixed bagasse concentration of 25 phr. The second group of mixes involves the addition of bagasse with concentrations varying from 10 to 50 phr at 10 intervals with fixed CB concentration of 40 phr. The sizes of the employed ground bagasse powder (GBP) in all prepared formulations ranged from 20 to 180 μm. In addition, 2.5 phr of maleic anhydride (MA) was added to enhance the interfacial adhesion between SBR and agricultural waste fillers (i. e. bagasse). Tensile strength, elongation at break, modulus at 100% elongation, resilience, hardness (Shore A), abrasion and degree of swelling of the rubber vulcanizates were studied. The prepared samples were also analyzed by scanning electron microscopy (SEM) to show the distribution of fiber and the occurrence of fiber-matrix adhesion. The optimum concentration of bagasse to be used simultaneously with CB in SBR composites was found to be 30 phr. Overall, it was found from the obtained results that the addition of GBP up to 50 phr is feasible without impairing the mechanical properties of SBR vulcanizates.
Control Strategies for Reactive Extrusion of Polypropylene by Peroxide Degradation A Brief Review and an Experimental Study
Authors: Wolf S. , Miethlinger J.
Published: November 2021

Industry 4.0 and digitalization are widely argued for the future success of numerous industrial solutions. Big data management might lead to the assumption that every issue can be solved numerically without any physical background. To some extent, this strategy will help within the plastics industry in general and in the extrusion technology in particular. However, a deep process knowledge together with process-relevant sensors, as well as the right process arrangements within the processing chain combined with smart data mining methods will be still the key success of industry 4.0. This presentation illustrates, based on a brief review on existing control strategies (Part 1), including sensory and predictive control models for reactive extrusion applied at a real-life on-site best practice project (Part 2), possibilities in combination of process tasks with digitalization approaches for PP-Polymer production. Specifically, rheological research conducted with a novel, patented multi-point rheometer (part 3), will provide a deeper insight into dynamic processes such as reactive extrusion. With those results and derivations thereof, improvements in predictive process control in addition to artificial control systems are made and might even lead to further interesting opportunities.

Published: November 2021

Biochar has been exploited as a substitution of carbon black in the rubber industry and various biochars exhibit diverse reinforcing abilities due to the different compositions. This work aims at studying the effect of silica on the modification process and reinforcing performance through the comparison of three biochars with different contents of silica, pyrolytic rice husks (PRH, 34 wt%), pyrolytic bamboos (PB, 7 wt%) and pyrolytic corn cobs (PC, 0.4 wt%). The results reveal that PRH requires higher rotational speed (300 min–1) than PB (200 min–1) and PC (200 min–1) to achieve similar particle sizes during the ball milling process because of the aggregations of higher silica content. Meanwhile, silica-rich pyrolytic biomass exhibits enhanced reinforcement on mechanical properties and thermal stability of rubber, and the elongation at break of vulcanizates continues to improve with increasing silica contents. Combined with the energy consumption and reinforcement, biochar containing a little amount of silica is more suitable to be widely used as bio-filler in rubber industry. This work should serve as a valuable reference to select appropriate biochar for the production of bio-fillers with high reinforcement.
Use of Image Analysis for Non-Destructive Testing of Thermoformed Food Packages
Authors: Ekşi O.
Published: November 2021

The aim of this study is to determine the thickness distribution of a food package using a non-destructive method. Initially, thickness measurements were carried out using an experimental procedure for thermoformed samples that were used for food packaging. Additionally, in this study, image analysis was used for the first time to determine the thickness distribution of the thermoformed products non-destructively. Image analysis software was employed for the estimation of thickness distribution. Measured thickness results were compared to those estimated using image analysis. Based on the results of the current study, image analysis may be an alternative method for non-destructive testing of thermoformed food packages even in a mass production line. Image analysis can be used to determine not only thickness distribution but also the weakest regions in a food package.
Transcultural Communication for a Polycentric World
Authors: Thussu Daya
Published: November 2021

In the era of digitized and globalized 24/7 communication, the one-way vertical flow of media and mediated culture from the West to the East has given way to multiple and horizontal flows, in which Asian countries are playing an increasingly significant role. This is having a profound impact on transcultural communication in a polycentric world. Although the United States and some other western countries still maintain their leading position in the field of global media and communication hardware and software. This article suggests that new actors, harnessing the potential of digital globalization, have emerged in the past decade and provide new avenues for transnational communication. Such changes, it argues, warrant a re-evaluation of how we define the global in terms of media and communication. Focusing on the growing global influence and digital presence of China and other Asian countries, the article suggests that the ascent of Asia contributes to further internationalizing of media and its study.
Angular momentum redirection phase of vector beams in a non-planar geometry
Authors: McWilliam Amy , Cisowski Claire Marie , Bennett Robert , Franke-Arnold Sonja
Published: November 2021

An electric field propagating along a non-planar path can acquire geometric phases. Previously, geometric phases have been linked to spin redirection and independently to spatial mode transformation, resulting in the rotation of polarisation and intensity profiles, respectively. We investigate the non-planar propagation of scalar and vector light fields and demonstrate that polarisation and intensity profiles rotate by the same angle. The geometric phase acquired is proportional to j = ℓ + σ, where ℓ is the topological charge and σ is the helicity. Radial and azimuthally polarised beams with j = 0 are eigenmodes of the system and are not affected by the geometric path. The effects considered here are relevant for systems relying on photonic spin Hall effects, polarisation and vector microscopy, as well as topological optics in communication systems.

Study of effect of wood-flour content on mechanical, thermal, rheological properties and thermoformability of wood-polypropylene composites
Authors: Marathe Deepti , Joshi Hemant , Kambli Pratiksha , Joshi Pramod
Published: November 2021

Wood plastic composites (WPC) were made from polypropylene (PP), impact copolymer (ICP) and wood flour (WF) by varying the WF content from 10 to 40% with PP grafted maleic anhydride as a coupling agent. The effect of varying WF content was studied on rheological, thermal, mechanical properties and dynamic mechanical properties. Experimental small amplitude oscillatory shear (SAOS) data was compared with the Einstein–Batchelor and empirical Krieger–Dougherty relations. Significant dependence of mechanical and rheological properties on WF content was observed. Young’s modulus, flexural modulus and dynamic shear viscosity increased with WF content. Results of dynamic mechanical analysis (DMA) showed increase in storage modulus with WF content. Three millimeter thick compression molded composites sheets were thermoformed using axisymmetric molds with two draw depths. Sag observed visually during thermoforming decreased with increasing WF content. Components made from the composites showed close to uniform thickness distribution as compared to those from ICP.
Boccaccios Überlegungen zum Ursprung der allegorischen Dichtung
Authors: Feddern Stefan
Published: November 2021

In this essay, the origin of poetry and its relationship to Holy Scripture as outlined by Boccaccio especially in theGenealogia deorum gentilium(GDG 14.8) are analyzed, both with a view to the reception of ancient authors and in particular against the background of the discourse on the relationship between poetry and theology since Thomas Aquinas. The article systematically examines the importance of the four characteristic features according to Boccaccio's understanding of poetry in the reconstruction of its origin: the special, metrically bound language, the divine object, allegory, and fiction.
Itinerario de un texto de Erasmo: elSermón de las misericordias de Diosen castellano (1528, 1544 y 1549)
Authors: Corradine Jimena Gamba
Published: November 2021

In this article, I study some aspects of the Spanish translation of Erasmus of Rotterdam’sDe immensa Dei misericordia concio: theSermón de la grandeza y muchedumbre de las misericordias de Dios. I review the context in which the three known editions (Logroño, 1528; Seville, 1544; Antwerp 1549) were produced in the light of other translations, such as the Italian one. I also examine the passages expurgated from the Latin text in Gaspar de Quiroga’s 1584 Inquisitorial Index and summarise critical opinion concerning the allegedly polemical nature of this pious work. According to some scholars, this apparently orthodox sermon by Erasmus may well have encouraged a rather heterodox interpretation in certain contexts.
On the elasticity of centres and the possibility of multiple roofs: revisiting some of Ulrich Ammon’s views on language variation and pluricentricity
Authors: Darquennes Jeroen
Published: November 2021

Against the background of a concise overview of Ulrich Ammon’soeuvrethis article first of all provides a constructive-critical account of some of the key concepts and questions that guided his macrosociolinguistic work on pluricentric languages and variation in German. In what follows, an attempt is made to further develop some of Ammon’s thoughts through emphasising the elasticity of the concept of pluricentricity and arguing for a creative use of the concept of “roofing” when describing the intricate interplay of standard and nonstandard varieties especially in language contact zones.
Monetary Policy and the Top 10%: A Time-Series Analysis Using ARDL and ECM
Authors: Omar Nadeen , Richter Christian
Published: November 2021

For the past decades, income inequality has been on the rise, and so is the frequency of its mentions in recent speeches by central bankers. With the heightened importance of the topic, this research aims to study the impact of monetary policy on income inequality. The study used dynamic models for the analysis, namely; the Error-correction Model (ECM) and the Auto-regressive Distributed Lag (ARDL) model to determine the relationship in both the short- and long-run. The data used were the top 10% income share and the short-term interest rate. Our main hypothesis is that changes in the short-term interest rate have a significant impact on the top 10% income share. We draw time-series evidence from a sample of nine economies at different stages of development: United States, United Kingdom, Russia, Germany, France, Greece, China, South Africa and Chile. The findings support the hypothesis with interestingly varying effects across our sample. These results provide important implications that can contribute in bettering policy setting and add to the discussion of the role of central banks in reducing income inequality.
Punctuation and text segmentation in 15th-century pamphlets
Authors: Neumann Marko
Published: November 2021

The use of punctuation in German incunabula is often described as arbitrary, irregular, and unsystematic (cf. Masalon 2014: 54–56). This concerns the inventory, frequency, and function of punctuation marks as well as pragmatic aspects such as how typesetters treated punctuation in their respective target texts. In this paper, punctuation is not seen as an independent linguistic subsystem, but as a means of text segmentation that – along with other measures (e. g. capital letters, pilcrows, and white space) – was used to structure a text with respect to its formal appearance, helping the reader to decode information. This case study is based on a corpus of German pamphlets written by the Bohemian astrologer Wenzel Faber and printed annually beginning in 1481 at various print shops, principally in Leipzig and Nuremberg. The analysis finds significant changes in the editions before and after 1490. These changes include an increasing consistency in the intensity of text segmentation, and a use of capital letters and punctuation marks developed from a polyfunctional to a monofunctional approach. Finally, different types of text segmentation are proposed, each characterized by a specific relationship between its frequency and its function. Despite this overall tendency, one must still take into account that typesetters followed individual punctuation practices in their search for suitable forms of text segmentation.

Authors: Schade Katrin , Müller Andre , Holdack Eric , Hübscher Marcus , Lurie Katja , Schulze Juana
Published: November 2021

This article deals with digitalization as a contribution to city center resilience, using Leipzig as an example. Focus group interviews illustrate that digital applications can attract to visit the city center and thus contribute to city center resilience. To reinforce these findings, the authors develop a prototype of a digital map covering Leipzig’s city center that is tested by means of 70 go-along interviews. The interviews show that linking digital functions and location-specific information thereby can be effective regarding city center resilience.

Secreted amyloid-β (Aβ) peptide forms neurotoxic oligomeric assemblies thought to cause synaptic deficits associated with Alzheimer’s disease (AD). Soluble Aβ oligomers (Aβo) directly bind to neurons with high affinity and block plasticity mechanisms related to learning and memory, trigger loss of excitatory synapses and eventually cause cell death. While Aβo toxicity has been intensely investigated, it remains unclear precisely where Aβo initially binds to the surface of neurons and whether sites of binding relate to synaptic deficits. Here, we used a combination of live cell, super-resolution and ultrastructural imaging techniques to investigate the kinetics, reversibility and nanoscale location of Aβo binding. Surprisingly, Aβo does not bind directly at the synaptic cleft as previously thought but, instead, forms distinct nanoscale clusters encircling the postsynaptic membrane with a significant fraction also binding presynaptic axon terminals. Synaptic plasticity deficits were observed at Aβo-bound synapses but not closely neighboring Aβo-free synapses. Thus, perisynaptic Aβo binding triggers spatially restricted signaling mechanisms to disrupt synaptic function. These data provide new insight into the earliest steps of Aβo pathology and lay the groundwork for future studies evaluating potential surface receptor(s) and local signaling mechanisms responsible for Aβo binding and synapse dysfunction.
From Progenitors to Progeny: Shaping Striatal Circuit Development and Function
Authors: Knowles Rhys , Dehorter Nathalie , Ellender Tommas
Published: November 2021

Understanding how neurons of the striatum are formed and integrate into complex synaptic circuits is essential to provide insight into striatal function in health and disease. In this review, we summarize our current understanding of the development of striatal neurons and associated circuits with a focus on their embryonic origin. Specifically, we address the role of distinct types of embryonic progenitors, found in the proliferative zones of the ganglionic eminences in the ventral telencephalon, in the generation of diverse striatal interneurons and projection neurons. Indeed, recent evidence would suggest that embryonic progenitor origin dictates key characteristics of postnatal cells, including their neurochemical content, their location within striatum, and their long-range synaptic inputs. We also integrate recent observations regarding embryonic progenitors in cortical and other regions and discuss how this might inform future research on the ganglionic eminences. Last, we examine how embryonic progenitor dysfunction can alter striatal formation, as exemplified in Huntington's disease and autism spectrum disorder, and how increased understanding of embryonic progenitors can have significant implications for future research directions and the development of improved therapeutic options.

SIGNIFICANCE STATEMENTThis review highlights recently defined novel roles for embryonic progenitor cells in shaping the functional properties of both projection neurons and interneurons of the striatum. It outlines the developmental mechanisms that guide neuronal development from progenitors in the embryonic ganglionic eminences to progeny in the striatum. Where questions remain open, we integrate observations from cortex and other regions to present possible avenues for future research. Last, we provide a progenitor-centric perspective onto both Huntington's disease and autism spectrum disorder. We suggest that future investigations and manipulations of embryonic progenitor cells in both research and clinical settings will likely require careful consideration of their great intrinsic diversity and neurogenic potential.
CYP17 T/C (rs74357) gene polymorphism contributes to polycystic ovary syndrome susceptibility: evidence from a meta-analysis
Authors: Liu Xingyan , Xu Mei , Qian Min , Yang Lindong
Published: November 2021

The cytochrome P450 family 17 (CYP17) is associated with hyperandrogenism in women, and the association between CYP17 gene polymorphism and the risk of polycystic ovary syndrome (PCOS) is not definitive. In order to determine whether the CYP17 T/C (rs74357) gene polymorphism is an exposure risk for PCOS, a comprehensive meta-analysis summarizing 19 studies was performed. The pooled odds ratio (OR) and the corresponding 95% CI were measured under five genetic models, and the stratified analyses by ethnicity, Hardy–Weinberg equilibrium, testosterone levels and BMI in controls were carried out to identify the causes of substantial heterogeneity. The overall results validated that the CYP17 T/C (rs74357) gene polymorphism was significantly associated with PCOS risk in four genetic models. Moreover, the outcomes of subgroup analysis by ethnicity indicated that the frequencies of the C allele of CYP17 T/C (rs74357) polymorphism were markedly higher in women from Asia than in Caucasians (T vs C: OR 0.85, 95% CI = 0.74–0.99, P < 0.05). Therefore, these findings suggested that the CYP17 T/C (rs74357) gene polymorphism played an indispensable part in increasing the susceptibility of PCOS when carrying the C allele, which proposed that the polymorphism of the CYP17 gene may be a predictive factor for the risk of PCOS or an important pathway in PCOS-associated metabolic and hormonal dysregulation.
Heterogeneous Monetary Policy Transmission in the US Housing Market
Authors: Christidou Maria , Konstantinou Panagiotis Theodore , Roumanias Costas
Published: November 2021

We assess the effects of monetary policy on real house prices and housing investment across the US states during the period 1983-2008. We find that an expansionary monetary shock generates higher housing investment and house prices at the national level. At the state level, however the responses of housing investment and house prices differ from the nation-wide responses. We relate this heterogeneity to various observable factors such as property tax rates, howeownership, income inequality, poverty and demographic factors. All these factors are crucial in explaining the heterogeneity of the state-level responses.
Dynamic spillovers between stock and money markets in Nigeria: A VARMA-GARCH approach
Authors: Salisu Afees A. , Isah Kazeem O. , Assandri Alberto
Published: November 2021

This study examines probable dynamic spillover transmissions between the Nigerian stock and money markets using the multivariate volatility framework that simultaneously accounts for both returns and shock spillovers. Based on relevant pre-tests, the VARMA-CCC-GARCH framework is selected and consequently employed to model the spillovers. The study finds significant cross-market return and shock spillovers between the two markets. Thus, a shock to one market is more likely to spill over to the other market. It is also observed that shocks have persistent effects on stock market volatility but transitory effects on money market volatility. In other words, shocks to the money market die out over time while shocks to stock market tend to persist over time. In addition, including lagged own shocks and lagged own conditional variance when forecasting the future volatility of both return series may enhance their forecast performance. An alternative approach proposed by Diebold and Yilmaz (2012) is also employed for robustness and the results are consistent with those obtained from the VARMA-CCC-GARCH model.
Economic Policy Uncertainty and the Co-Movement between REITs and Exchange Rate
Authors: Raheem Ibrahim , Fasanya Ismail O. , Yusuf Agboola H.
Published: November 2021

The REITs market has attracted a lot of interest among the academic, policymakers, and market participants. The linkages between REITs and macroeconomic and financial variables have been adequately explored in the literature, with more emphasis on linear models. This study expands the frontier of knowledge by examining the role of uncertainty in the comovement/spillover between REITs and the currency markets. Some interesting results were observed. First, using the Diebold and Yilmaz (2012) spillover test, we find that there is strong connectedness between the REITs and currency markets. Second, the BDS test shows that nonlinearity is a very crucial factor to be put into consideration when examining the role of EPU in affecting the interactions between REITs and exchange rate markets. Third, the non-parametric causality-in-quantile test confirms that the connectedness between the markets and EPU is stronger around the lower and middle quantiles. These results have important policy implications for policymakers and market participants. The study also offers suggestions for future research.
Testing for Restricted Stochastic Dominance: Some Further Results
Authors: Davidson Russell
Published: November 2021

Extensions are presented to the results of Davidson and Duclos (2007), whereby the null

hypothesis of restricted stochastic non dominance can be tested by both asymptotic and

bootstrap tests, the latter having considerably better properties as regards both size and

power. In this paper, the methodology is extended to tests of higher-order stochastic dominance.

It is seen that, unlike the first-order case, a numerical nonlinear optimisation problem

has to be solved in order to construct the bootstrap DGP. Conditions are provided for a

solution to exist for this problem, and efficient numerical algorithms are laid out. The empirically

important case in which the samples to be compared are correlated is also treated,

both for first-order and for higher-order dominance. For all of these extensions, the bootstrap

algorithm is presented. Simulation experiments show that the bootstrap tests perform

considerably better than asymptotic tests, and yield reliable inference in moderately sized

samples.
Is the economic crisis over (and out)?
Authors: Abadir Karim M.
Published: November 2021

This note analyzes the recent global recession: its causes, the predictability of the timing of its start and of its end, and the implications for macro policy. These follow from the general-equilibrium macro model of Abadir and Talmain (2002) and its implications for a new type of macroeconometrics. The note also proposes some banking regulations, and presents prospects for the future.

Measuring the Unemployment Risk in Northern Greece from the LFS Micro-Data during the Period 1994-2006
Authors: Rodokanakis Stavros , Vlachos Vasileios A.
Published: November 2021

This paper investigates unemployment risk and job prospects of individuals in the three Northern Greek regions (Central Macedonia, Western Macedonia, and Eastern Macedonia and Thrace), during the implementation of the second (1994-99) and the third (2000-06) Community Support Frameworks. More specifically, the research focuses on the social and demographic characteristics that increase the chances of individuals in finding a job, and explores the impact of gender, age, marital status, residence location, level of education, immigrant status, registered in the Manpower Employment Organization (OAED) and participation in training courses. Furthermore, there is an investigation whether University graduates face greater difficulties in finding a job than non-University graduates, as a series of studies or aggregate statistics for Greece conclude. Sampling is based on individual anonymized records (micro-data) of the Labour Force Survey for both employed and unemployed at Nomenclature of Territorial Units for Statistics-2 level. The findings of the logit model are mixed for all the variables used, apart from those of registered in OAED for which the results have no differences among regions and years.
The Effects of Central Bank Independence and Inflation Targeting On Macroeconomic Performance: Evidence from Natural Experiments
Authors: Parkin Michael
Published: November 2021

I investigate the effects of central bank independence and inflation targeting on macroeconomic performance in 26 advanced economies during the period 1980 to 2011. I find that both improve macroeconomic performance but inflation targeting is the more effective arrangement. When a central bank becomes more independent, it lowers the inflation rate and the variability of inflation but has no effect on real GDP or unemployment. When a central bank becomes an inflation targeter, it lowers the inflation rate, the variability of inflation, the variability of real GDP growth and the output gap, and has no effect on unemployment.

Sunny Upside? The Relationship Between Sunshine and Stock Market Returns
Authors: Smith Gary , Zurhellen Michael
Published: November 2021

Weather can have profound effects on economic activity, most obviously agriculture, construction, and transportation. It has also been argued that the daily weather in New York City affects daily U.S. stock returns, a clear challenge to the efficient market presumption that rational investors will not let their assessment of a stock’s value be swayed by whether the sun happens to be shining. Studies claiming to have found a sunshine effect are clouded by differing methodologies which may have been chosen to buttress their results. We examine a fresh set of data and confirm the existence of a New York City sunshine effect which has weakened over time as trading has become more geographically dispersed.
Friedman Meets Hayek on Money and Prices in Canada
Authors: Chu Kam Hon
Published: November 2021

Though both classical liberals, Friedman adopted the quantity theory of money and used the general price indexes and aggregate data in empirical analysis, whereas Hayek rejected aggregative analyses as potentially misleading and focused on the impact of money on relative prices in his business cycle theory. This study shows theoretically that when the central bank minimizes the monetary shock to maintain stability in the general price level, it also maintains simultaneously relative price stability, thus narrowing the divergence between Friedman and Hayek. This finding is empirically verified by Canada’s experience with inflation targeting since 1991
Unemployment and Organizational Commitment: Evidence from a Panel of Australian Manufacturing Firms
Authors: Apergis Nicholas
Published: November 2021

Higher unemployment increases the cost of job loss and heightens employees’ feelings of job insecurity. The paper argues that these two effects could have a positive influence on employee organizational commitment. Using data from the Household, Income and Labor Dynamics in Australia (HILDA) microdata database, we find that employees in high unemployment regions are more committed to their organization, while the effect of unemployment on employee’s commitment is stronger in the private sector.

Published: November 2021

The objective of this study was to evaluate the extent to which the practicing architects in Malaysia were familiar with timber products as a construction material. The materials consumption data was extracted from the Construction Industry Development Board (CIDB) database and was used to conduct a survey among 189 respondent architects. The results indicated that the architects were familiar with common timber products such as plywood, fiberboard, particleboard, and laminated veneer lumber. Correlation analysis of awareness and knowledge against the rate of utilization of these timber products was significant. Furthermore, the most important deterrent factors for the use of timber products in building construction in Malaysia were the high cost, poor durability, restrictive building codes and by-laws, as well as the low fire resistance. More aggressive promotion of timber products as a potential construction material is advisable to be undertaken when the goal is to boost the material’s use in the construction industry. Policy makers may also consider providing financial incentives to increase timber products utilization in building construction in Malaysia.
On approximation by splines of solution of boundary problem
Authors: Dronov S.G.
Published: November 2021

For the boundary problem$$y'' + p(x) y' + q(x) y = r(x), \; y(a) = Y_a, \; y(b) = Y_b$$we give the approximate solution method of fourth order of accuracy in the form of cubic spline. For truncated problem ($p(x) \equiv 0$) we establish the prior estimates of error.

For the quadrature formula (with positive, continuous weight function) that is defined by the values of the function and its derivatives of up to and including $(r-1)$-th order, we find necessary conditions of optimality on the classes $W^r_p$, $r = 1, 2, \ldots$, $p = 2$, $p = \infty$.
Asymptotic optimal control over elliptic system with special characteristics
Authors: Gorgo Yu.N.
Published: November 2021

We construct and substantiate the solution of two-dimensional problem of the optimal distributed control over elliptic system with small parameter at higher derivative in an elementary region - in a square. We assume that the characteristics of limit control coincide with part of region boundary, and the control is unbounded.We show that the solutions of this problem have increasing singularities on some internal sets and, therefore, that the problem is bisingular.

Sigrid Pôrto de Barros
Authors: Faria Ana Carolina Gelmini de
Published: November 2021

O trabalho analisa indícios da trajetória de uma conservadora de museus, Sigrid Pôrto de Barros, no campo dos museus brasileiro. Centra-se na década de 1950, quando se tornou funcionária do Museu Histórico Nacional, até a década de 1970, momento em que foi chefe da Seção de Pesquisa e Assistência Pedagógico-Museográfica da Divisão de Atividades Educacionais e Culturais do Museu. Embora seja uma profissional pouco reconhecida na historiografia do campo, sua atuação evidencia uma carreira voltada para a consolidação da função educativa dos museus, com ênfase no atendimento do público escolar infantil por meio de estratégias de execução nos museus dos princípios da Escola Ativa. Para a investigação foram analisados relatórios, escritos da profissional e outras fontes que favoreçam a compreensão de como a educação em museus era debatida no período. O conceito de intelectual mediador (GOMES; HANSEN, 2016) embasa a construção argumentativa da pesquisa. A análise revela que profissionais do campo dos museus, parte expressiva composta por mulheres no Brasil, estavam atualizadas com os debates sobre educação e suas possíveis articulações com os museus, e que suas atuações legitimaram essas instituições como espaços de aprendizado, função que se tornou marca expressiva no papel contemporâneo dos museus.
