COGNITIVE AND SOCIODEMOGRAPHIC FACTORS AS BACKGROUND OF THE INVESTMENT DECISION
Authors: Gabriel Cristian Mateus Pereira , Ribeiro Ivano
Published: June 2023

The study aims to analyze the relationships between behavioral and sociodemographic factors with the investment decision of Brazilian academics in business areas. In order to achieve the research objectives, descriptive research with a quantitative approach was used. The procedures used in the study were Survey survey research and Structural Equation Modeling (Structural Equation Modeling – SEM). The main results highlighted that academics have a positive perception about money, most of them save part of their monthly earnings. However, notice a significant portion that has an expense equivalent to the gain. As far as the results from the Structural Equation Model are concerned, all variables with the exception of salary are related to investment decisions. The exogenous variables curiosity/trust and socialization/family showed positive correlations in relation to investment decisions based on the investor profile. While risk aversion, education level and college period have a negative correlation with individuals' investment decisions. The study's contributions show how behavioral and sociodemographic factors interfere in individuals' investment decisions, in addition to demonstrating how knowledge can significantly act within individuals' everyday decisions. Factors such as socialization play a significant role in disseminating knowledge about finance among individuals
PSYCHOSOCIAL BACKGROUND TO THE USE OF SOCIAL MEDIA MARKETING AND ITS IMPACT ON BUSINESS
Authors: Faria Luiz Henrique Lima , Francischeto Bruno Tardin , Teixeira Rafael Buback , Medeiros Rodrigo Loureiro
Published: June 2023

International studies have focused on the use of information and communication technologies (ICTs) in the micro and small business sector. Micro and small enterprises (MSEs) sustain a fundamental role in the Brazilian and international economic scenario, contributing substantially to the social development of their countries. Based on the theoretical motivation founded on the need to understand the psychosocial factors that precede the use of social media marketing and its impact on business in the context of Brazilian micro and small businesses, as well as to make comparisons with correlated international studies, this study aimed to analyze the relationships among antecedent variables to the use of social media marketing and its impact on business in Brazilian micro and small businesses. To reach this objective, data were collected by means of a survey applied on a sample of 82 Brazilian MSEs. These data, after tabulated, were analyzed by the method of Structural Equation Analysis by Partial Least Squares (PLS-SEM), resulting in the non-rejection of the five hypotheses tested in this study. Thus, it was verified that the psychosocial variables Facilitating Conditions (CF), Compatibility (COM), Perceived Usefulness (UP), Cost (C), Perceived Ease of Use (FUP) are antecedent variables to the Use of Social Media Marketing (USE) and, the latter, antecedent to Business Impact (IN). From these results it was possible to make comparisons with international studies.

Authors: Feliciano Gabriely , Pereira Flávio Raposo
Published: June 2023

Through the high competitiveness of the market and the high level of customer demand, companies sought opportunities to modernize their processes in order to offer quality products and services, with high flexibility and innovation content with lower cost and shorter delivery time. This research seeks to reduce the cycle time of the filling process of a cosmetics industry. For this, the DMAIC methodology was used to map the flow, measure and classify its variables, analyze the data to identify the root cause, propose improvements to the process and manage the performance indicators during the development of the activities. In order to achieve the proposed desires, this research relied on the application of the concepts and tools addressed by Lean Six Sigma. Based on the results, it was seen that there was a reduction in cycle time of 14.86%, where the current state that was 64.74 seconds became 55.12 seconds in the future state.
Формализованный подход к проектированию микропроцессорных систем с элементами человеко-машинного взаимодействия
Authors: Ковалев И. В. , Лосев В. В. , Калинин А. О.
Published: June 2023

В статье рассматривается методология формализованного подхода по проектированию микропроцессорных систем, обеспечивающих человеко-машинное взаимодействие. Рассмотрены классические процедуры проектирования последовательностных систем (схемной логики), применимые для разработки МП-систем, в частности формальные методики получения таб­лиц переходов/выходов и графа проектируемого автомата. Основной акцент проектирования строится на логике графа автомата Мили, характеризуемый тем, что в течение всего периода «устойчивого» состояния Qi входной Хi и вы­ходной Zi векторы остаются неизменными. Однако, при этом условные операторы алгоритма селектируют изменения входного вектора Xi, если оно произошло в состоянии Qi под воздействием внешних по отношению к МП-системе со­бытий. В результате такой селекции МП-система перехо­дит к иному «устойчивому» состоянию Qi+k, которое опре­делено схемой алгоритма. В качестве примера проектируемой МП-системы выступает контроллер вызова управляющих подпрограмм, соответствующих конкретным режимам работы объекта управления. Предложено программное решение участка алгоритма, обеспечивающего условный переход по результатам реализации процедуры сравнения констант. В качестве обоснования функциональной реализации прототипа проектируемого контроллера приведена принципиальная электрическая схема на базе микроконтроллера, обеспечивающая элементы человеко-машинного взаимодействия.
АНАЛИЗ КОЛИЧЕСТВЕННЫХ И КАЧЕСТВЕННЫХ ИЗМЕНЕНИЙ ПАРАМЕТРОВ СМАЗОЧНОЙ СИСТЕМЫ В ПРОЦЕССЕ ЭКСПЛУАТАЦИИ ДИЗЕЛЯ

"Проведен анализ тенденций изменения параметров смазочной системы дизелей в процессе эксплуатации с количественных и качественных позиций. С учетом экспоненциальной зависимости зазора от наработки в работе получена зависимость давления масла от наработки. В результате математической обработки экспериментальных данных определена зависимость давления в системе смазки от наработки двигателей для автомобилей КамАЗ-740 и ЯМЗ-236. Проведенные расчетно-аналитические и экспериментальные исследования показали, что толщина масляного слоя в зависимости от наработки снижается по экспоненциальной зависимости. Математическая обработка экспериментальных данных позволила определить параметры этой зависимости для двигателей КамАЗ-740. Приведены три этапа трения, исходя из условий взаимодействия микро выступов сопряженных поверхностей. На первом этапе до величины толщины масляного слоя не менее 20 мкм наблюдается благоприятный режим жидкостного трения с очень малой вероятностью контакта микро выступов. На втором этапе при величине ТМС от 20 до 15 мкм повышается вероятность контакта микровыступов и наблюдается полужидкостное трение. На третьем этапе при h < 15 мкм значительно возрастает вероятность контакта микро выступов, что может привести к проворачиванию вкладышей. Снижение вязкости масла повышает вероятность нарушения гидродинамического трения в сопряжениях. Одним из важных контролируемых параметров смазочной системы является уровень масла в картере. Однако даже при неизменном уровне качественные показатели могут значительно различаться. Это необходимо учитывать при разработке систем бортового диагностирования дизелей. "

Multi-Disciplinary Education of Teaching and Learning in Higher Education
Authors: Mrs. Archana Sharma
Published: June 2023

Multidisciplinary education is a unique educational approach that allows the student to learn and explore different subjects or curriculum from various disciplines. A multidisciplinary curriculum is one in which a single topic is studied from the viewpoint of more than one discipline. Multidisciplinary education is important because it helps to bring number of ideas and perspectives from different subjects, and therefore may be able to offer alternative ways of looking at issue or problems. The evolution of world is happening very fast in terms of learning and technology, A whole lot of subjects are being born out of necessity and it is only going to increase over time. Particular skill and its specialization is very necessary to survive in today's competitive environment, with the help of job, they would have a financial support and to hinder their progress in education ,where people would study different subjects allowing them to get a job easier as a result of dipping their tools into very different streams. Another important reasons why multi disciplinary education should be promoted is that there is a greater emphasis on employability there are a lot of students who graduate from college with fairly decent CGPA but do not have a particular skill to be employable by a company. Employability is directly limited to the knowledge that a student possesses about a particular subject.

Petrarch and the Making of Gender in Renaissance Italy
Authors: McHugh Shannon
Published: June 2023

This book is a new history of early modern gender, told through the lyric poetry of Renaissance Italy. In the evolution of Western gender roles, the Italian Renaissance was a watershed moment, when a confluence of cultural developments disrupted centuries of Aristotelian, binary thinking. Men and women living through this upheaval exploited Petrarchism’s capacity for subjective expression and experimentation - as well as its status as the most accessible of genres - in order to imagine new gendered possibilities in realms such as marriage, war, and religion. One of the first studies to examine writing by early modern Italian men and women together, it is also a revolutionary testament to poetry’s work in the world. These poets’ works challenge the traditional boundaries drawn around lyric’s utility. They show us how poems could be sites of resistance against the pervading social order - how they are texts capable not only of recording social history, but also of shaping it.
The People’s Petrarch :
Early Modern Italian Readers
and the Gender of Celebrity
Authors: McHugh Shannon
Published: June 2023

This chapter explores Petrarch’s gendered portrayal in early modern
printings of his lyric, with particular attention to Alessandro Vellutello’s
edition of 1525. Vellutello rejected Petrarch’s own ordering, rearranging
the poems into a linear, amorous plotline, and adding such paratexts as a
“biography” of Laura and a map of the lovers’ environs. Often dismissed by
sixteenth-century humanists and modern-day scholars alike, Vellutello’s
Petrarch was the most popular of the period, embraced by readers who
were enamored of its hybridity between critical edition and fan fiction.
Theorizing a gendered contrast between Petrarchan fame and celebrity,
I explore the evolution of Petrarch in the early modern imagination, an
investigation that underpins subsequent chapters’ examinations of how
Petrarchan imitators used literature to remake gender.
Ventriloquized Lyric
Authors: McHugh Shannon
Published: June 2023

The capacity of the lyric voice to take on a life removed from the author’s
gender identity is nowhere clearer than in Petrarchism’s rich tradition of
ventriloquized verse. During the Italian Wars (1494–1559), men adopted
women’s voices, after the model of Ovid’s Heroides, as a new way to explore
the tragedies of battle. In the second half of the sixteenth century, literary
giants such as Tasso and Guarini exchanged amorous verse in which one
writer played the role of the female beloved. In the same decades, women
writers assumed male personae as a means to experiment with erotic verse.
Men’s and women’s engagement in poetic ventriloquism demonstrates
the malleability of gendered lyricization and its usefulness in testing the
boundaries of societal norms.
Religious Lyric*
Authors: McHugh Shannon
Published: June 2023

This chapter examines religious lyric from approximately 1530 to 1630,
from the birth of the spiritual canzoniere with Vittoria Colonna to the
definitive edition of Angelo Grillo’s landmark Pietosi affetti. Mixing devotion
with desire, spiritual Petrarchists looked to incite readers to religious
fervour using imagery that could be sensuous, erotic, or even perverse. In
the Counter-Reformation in particular, this verse became increasingly
corporeal and gender-ambiguous: sensual blazons of the body of Mary
Magdalene; male-authored impersonations of saintly women; fantasies of
touching, kissing, or penetrating Christ’s wounds. Such verse is evidence
of writers’ exploration of the surprising space between gender norms that
was opened up by the Counter-Reformation.

Anna Maria Van Schurman’s Chinese Calligraphy
Authors: Weststeijn Thijs
Published: June 2023

Calligraphy is an understudied aspect of the reception of Chinese art in early modern Europe. Chinese visitors to Middelburg (1601) and Amsterdam (1654) first demonstrated it as a cultural practice. Other written samples circulated in the Dutch Republic, an emporium for Chinese goods. This article focuses on a previously unknown participant in this exchange: Anna Maria van Schurman, Europe’s first female university student, who had mastered various Asian scripts and was expected to try her hand at Chinese and Japanese. In 1637 Andreas Colvius sent her samples of East Asian calligraphy to copy ‘by her own hand’. This exchange makes possible a transcultural study of the calligraphic gift. Via the popular writings of Matteo Ricci,  Van Schurman’s correspondents may have learned about the role of calligraphy in fostering social relationships in late Ming China. Some of the visual and material qualities of East Asian writing must have made it look like a fitting tribute to a female European scholar of high profile and, in being exchanged as a gift, calligraphy acquired new meanings even while remaining illegible. In seventeenth-century China and Europe, the friendly exchange of calligraphy expressed new forms of sociability.
Uncertainties originating from GCM downscaling and bias correction with application to the MIS-11c Greenland Ice Sheet
Authors: Crow Brian R. , Tarasov Lev , Schulz Michael , Prange Matthias
Published: June 2023

Abstract. The Marine Isotope Stage 11c (MIS-11c) interglacial is an enigmatic period characterized by a long duration of relatively weak insolation forcing, but is thought to have been coincident with a large global sea level rise of 6–13 m. The configuration of the Greenland Ice Sheet during the MIS-11c interglacial highstand is therefore of great interest. Given the limited data constraints, model-based analysis may be of use, but only if model uncertainties are adequately accounted for. A particularly under-addressed issue in coupled climate and ice sheet modeling is the coupling of surface air temperatures to the ice model. Many studies apply a uniform “lapse rate” accounting for the temperature differences at different altitudes over the ice surface, but this uniformity neglects both regional and seasonal differences in near-surface temperature changes. Herein we provide the first such analysis for MIS-11c Greenland that addresses these uncertainties by comparing 1-way coupled CESM and ice sheet model results from several different downscaling methodologies. In our study, a spatially- and temporally-varying temperature downscaling method produced the greatest success rate in matching limited paleodata constraints, and suggests a peak ice volume loss from Greenland during MIS-11c of near 50 % compared to present day (~3.9 m contribution to sea level rise). This result is on the lower bound of existing data- and model-based studies, partly as a consequence of the applied one-way coupling methodology which neglects some feedbacks. Additional uncertainties are examined by comparing two different present-day regional climate analyses for bias correction of temperatures and precipitation, a spread of initialization states and times, and different spatial configurations of precipitation bias corrections. No other factor exhibited greater influence over the simulated Greenland ice sheet than the choice of temperature downscaling scheme.
Large structures simulation for landscape evolution models
Authors: Coatléven Julien , Chauveau Benoit
Published: June 2023

Abstract. Because of the chaotic behavior of the coupling between water flow and sediment erosion and transport, without any special treatment the practical results of landscape evolution models (LEM) are likely to be dominated by numerical errors. This paper describes two areas of improvement that we believe are necessary for the successful simulation of landscape evolution models. The first one concerns the expression of the water flux that was initially rebuilt in a recent paper in a mathematically consistent way for the cell-to-cell multiple flow direction algorithms, thanks to a reinterpretation as a well chosen discretization of the Gauckler-Manning-Strickler continuous equation. Building on those results, we introduce here a general framework allowing to derive consistent expressions of the water flux for the most commonly used multiple/single flow direction (MFD/SFD) water flow routines, including node-to-node versions. If having a consistent water flux is crucial to avoid any mesh size dependence in a LEM and controlling the consistency error, the expected non-linear self amplification mechanisms of the water and sediment coupling can still lead to simulations blurred by numerical errors. Those numerical instabilities being highly reminiscent of turbulence induced instabilities in computational fluid dynamics (CFD), in the second part of our paper we present a ``large structure simulation'' (LSS) approach for LEM, mimicking the large-eddy simulations (LES) used for turbulent CFD. The LSS allows to control numerical errors while preserving the major physical based geomorphic patterns.
THE ARCHITECTURAL GEOMETRY OF THE CHURCH OF CRISTO OBRERO Y NUESTRA SEÑORA DE LOURDES
Authors: Melachos F. C. , Florio W. , Rossato L. , Maietti F.
Published: June 2023

Abstract. The object of study of this paper is the Church of Cristo Obrero y Nuestra Señora de Lourdes, in the city of Atlántida, Uruguay, designed and built by Uruguayan engineer Eladio Dieste between 1956 and 1960, and proclaimed as a UNESCO World Heritage Site in 2021. Furthermore, the object of study is the outset of Eladio Dieste’s experimentations with reinforced brickwork, which resulted in innovative thin-shell structural typologies. Hence, the objective of this article is to verify the geometrical relationships within the continuous gaussian vaults of the Cristo Obrero’ roof and the ruled surfaces of its lateral walls. The proposed methodological procedures for this research were the in situ visitation of the object of study, followed by the consultation of original construction drawings, as well as the exploratory parametric modeling and polynomial regression of the architectural geometry of the Church of Cristo Obrero. Amongst the expected contributions for this research reside the dissemination of Latin-American modern architectural heritage sites within European academic journals, digital design technologies within Latin-American research centres, as well as the fostering of the comprehension of the design and construction process of the Uruguayan engineer Eladio Dieste.
METHODOLOGY AND MEANING OF THE 3D MODELLING OF THE LOST BAALSHAMIN TEMPLE IN PALMYRA
Authors: Michel P. M.
Published: June 2023

Abstract. The Baalshamin temple in Palmyra was completely destroyed by ISIL in 2015. To address this issue, the “Collart-Palmyre Project” at the University of Lausanne (UNIL) digitally published the scientific archive of Paul Collart who was in charge of the excavation of the temple in the 1950’. Since 2017, the Project makes the archives accessible on an online open access database (tiresias.unil.ch). A 3D reconstruction of the temple has been realized by the UNIL team in collaboration with ICONEM. The 3D models (including handily drawn elements) are now being integrated onto a PoTree platform ( https://github.com/potree/potree) that allows archival items to be geolocated, associating them with the architectural or archaeological objects they document.The challenge here was to access metadata on the 3D model and to ease access to the archives through online tools.We also published a diachronic 3D model showing the different periods of occupation of the site (from the second century BC to the ninth century AD). Partnership with NGO’s also permit the presentation of 3D models to displaced Syrian refugees in the Spirit of the Faro Convention. Last but not least, the Project follows the guidelines of the London Charter and the Sevilla principles for Virtual Archaeology and questions the broader facets of neo-colonialist, economic and nationalist agendas that emerges from the 'migration of digital heritage' as assets to be exploited. This project wants to explore how these digital assets provide a scaffold for the memories of migrants.

Authors: Murtiyoso A. , Grussenmeyer P.
Published: June 2023

Abstract. In recent decades, photogrammetry has re-emerged as a viable solution for heritage documentation. Developments in various computer vision methods have helped photogrammetry to compete against the laser scanning technology, eventually becoming complementary solutions for the purpose of heritage recording. In the last few years, artificial intelligence (AI) has progressively entered various domains including 3D reconstruction. The Neural Radiance Fields (NeRF) method renders a 3D scene from a series of overlapping images, similar to photogrammetry. However, instead of relying on geometrical relations between the image and world spaces, it uses neural networks to recreate the so-called radiance fields. The result is a significantly faster method of recreating 3D scenes. While not designed to generate 3D models, simple computer graphics methods can be used to convert these recreated radiance fields into the familiar point cloud. In this paper, we implemented the Nerfacto architecture to recreate two instances of heritage objects and then compared them to traditional photogrammetric multi-view stereo (MVS). While the initial hypothesis posits that NeRF is not yet capable to reach the level of accuracy and density achieved by MVS as can be observed in the results, NeRF nevertheless shows a great potential due to its fractionally faster processing speed.

Published: June 2023

Abstract. Small and medium-sized museums have been particularly impacted by the COVID-19 pandemic, as they often have limited resources and staff to manage the challenges posed by the pandemic. In order for them to survive during the pandemic but also embracing the extensive use of technology in our everyday lives, museums have to adapt to this new reality. The aim of the Museum-Next project is to provide small and medium-sized museums with a new generation of specialised EU professionals working in the Cultural Heritage sector, equipped with a recognised, cross-cutting and high-level digital skillset: the Digital Curators. In the digital age, museum digital curators play a critical role in preserving, organising, and presenting museum collections online. As part of the project, our research performed a desk analysis on the state of the art on museum digital transition strategies and museum digital curator training programs already implemented at EU scale in order to map good practices and tools already existing so as to highlight the current situation and the gaps that may appear in the topic.

Abstract. DIGI-ORCH is a research project with objectives, on one hand, to design and develop "smart" brochures for concerts and educational programs of the State Conservatory of Thessaloniki (Greece), and, on the other, to develop an innovative system for the visualization of information on smart mobile devices (smartphones and tablets). The application of Augmented Reality (AR) provides free access to the information and content of the above concerts and educational programs, combining the information of a robust data server and an easy-to-use user interface of the smart device in real-time.The pilot implementation of the system in real conditions took place at the beginning of December 2022, in an event held at the facilities of the State Conservatory of Thessaloniki. The event was an evening of Chamber Music entitled Musical Kaleidoscope, with the internationally acclaimed artists Simos Papanas (violin), Dimos Goundaroulis (violoncello), and Vassilis Varvaresos (piano). They performed the Piano Trio no. 3 in G minor, Robert Schumann's opus 110, and the Piano Trio no. 2 in E flat major, Op. 100 D. 929 by Franz Schubert. The concert was attended by over 150 attendees.The paper will present the chaîne-operatoire of the development of the system, from the acquisition of raw data (text, video, image, and sound) to the methodology used to produce the "smart" event brochure and the AR application for the above concert. Essentially, this large amount of information that cannot be assessed by a regular printed concert brochure is included in the smart system and displayed on the mobile device when the user locates the appropriate AR patterns on the surface of the analog concert poster and/or on the pages of the brochure.This information comprised of ie. additional text and images about the composers and their musical projects, about the musicians of the concert (e.g. biographies), their interviews and rehearsals (video) before the concert, information about the State Conservatory of Thessaloniki (text, video, image, and sound), 3D models of musical instruments, 360° of the concert space, etc. diverse multimedia material.

Published: June 2023

Abstract. The digitisation of museum exhibits has played an essential role in geomatics research for generating digital replicas, as it offers the chance to address rather challenging issues. The use of different sensors, ranging from active to passive, and also structured light scanners or hybrid solutions, the various destinations and purposes of the final results combined with the extreme variety of possible objects have made it a field of investigation highly inquired in the literature.The present study aims to analyse and discuss a digitalisation workflow applied to four Sumerian civilisation masterpieces preserved in the British Museum. The dense and accurate 3D point clouds derived from a specimen of Articulated Arm Coordinate Measuring Machines in collaboration with Faro technologies have twofold roles: ground truth and geometric reference of the final digital replicas. Digital photogrammetry is employed to enrich the models with the relevant radiometric component. The significant contribution results, exploiting co-registration strategies, offer careful guidance of a photogrammetric protocol created in a highly controlled environment combined with skilful expedients and devices. The proposed approach enables the acquisition of high-quality and radiometrically balanced images and improves the possibility of automating the masking procedure before the photogrammetric processing.

Abstract. Modern terrestrial laser scanners and photogrammetric imaging systems can provide highly accurate and objective as-built records of existing architectural, engineering, and industrial sites. This comprehensive digital recording benefits culturally significant places like heritage buildings, monuments, and other vital structures. The collected data can be instrumental in various ways, including aiding in conservation, management, monitoring and repair efforts and serving as an educational resource for scholars and the general public. These technical capabilities are especially well-suited for architecturally complex, ornate buildings like the Aachen Cathedral UNESCO World Heritage site. This paper describes the recent recording efforts at the Aachen Cathedral and is a comparative study of the previous documentation work done at the Cologne Cathedral.The 3D documentation of the Aachen Cathedral UNESCO World Heritage Site is an ongoing collaborative project between the Sapienza Università di Roma, Rome, Italy, Robert Gordon University, Aberdeen, Scotland, and in partnership with RWTH Aachen University, and the Dombauhütte Aachen.
DIRECT GEOREFERENCING APPROACHES FOR CLOSE-RANGE AND UAV PHOTOGRAMMETRY IN THE BUILT HERITAGE DOMAIN
Authors: Teppati Losè L. , Chiabrando F. , Maschio P.
Published: June 2023

Abstract. Direct georeferencing uses onboard sensors to measure the position and orientation of the camera during image acquisition for photogrammetric applications. This approach aims to eliminate the use of traditional Ground Control Points (GCPs) in the photogrammetric process in order to reduce the costs and the time of the survey operations. The direct georeferencing technique involves integrating measurements from inertial measurement units (IMUs) and Global Navigation Satellite Systems (GNSS) data in order to evaluate the position and attitude of the camera with high accuracy (a few centimeters). In the Built Heritage survey domain, this approach is mainly followed by the employment of UAVs (Uncrewed aerial systems) platforms that are nowadays equipped with highly accurate systems able to evaluate the external parameters for the photogrammetric process. For terrestrial applications, few already achieved tests were performed; moreover, the sensors today available for extracting information from close-range acquisition systems are limited and sometimes under development. To evaluate the possibility offered by these new direct georeferencing tools, a test on the 3D ImageVector (REDcatch GmbH) has been performed. The results and the strategies followed will be presented and analyzed in order to understand better the accuracy and the potentiality of this new promising approach.

Authors:   , Bentley Laura
Published: June 2023

Self-regulation is a key competency in early childhood and plays an important role in early academic skills and social-emotional development. Rhythm and movement have been established as effective ways to improve early self-regulation. This thesis contributed to the growing body of evidence around the novel Rhythm and Movement for Self-Regulation (RAMSR) program by evaluating intervention effects on child outcomes, six months after receiving the intervention. The implementation experiences for educators were also explored through a two-phase survey and a series of interviews to better understand the facilitators and barriers of implementing the RAMSR program.
Exploring the Channel of Transmission between External Debt and Economic Growth: Evidence from Lower Middle Income Countries
Authors: Haque Muhammad Hammad Ul , Iftikhar Khurram , Rizvi Syed Zia Abbas
Published: June 2023

The study intends to ascertain the pathway through which foreign debt affects GDP growth in lower-middle-income countries (LMICs). High external debt stock has been major source concern for many LMICs in the late 90’s and post financial crises period. Cross-section panel data from 30 countries were studied for the period 1999–2019 using a two-step system (GMM) estimation technique. The sample LMICs were further broken into Asian and African nations and the period was divided into 2010–2019 to assess the impact of post-financial crisis events. The research revealed a strong relationship between external debt and GDP growth via total factor productivity when the entire sample of LMICs was considered. However, the estimations also indicated that TFP is not a channel of transmission in Asian nations in both eras, namely 1999–2010 and the post-financial crisis period of 2010–2019, because foreign debt reduces total factor productivity. Furthermore, considering the entire sample and the post-financial-crisis period in African countries, external debt has a negative but minor connection with TFP. GDP growth shows a large and positive association with TFP in both periods in African countries.
