Bayesian atmospheric correction over land: Sentinel-2/MSI and Landsat 8/OLI
Authors: Yin Feng , Lewis Philip E. , Gómez-Dans Jose L.
Published: November 2022

Abstract. Mitigating the impact of atmospheric effects on optical remote sensing data is critical for monitoring intrinsic land processes and developing Analysis Ready Data (ARD). This work develops an approach to this for the NERC NCEO medium resolution ARD Landsat 8 (L8) and Sentinel 2 (S2) products, called Sensor Invariant Atmospheric Correction (SIAC). The contribution of the work is to phrase and solve that problem within a probabilistic (Bayesian) framework for medium resolution multispectral sensors S2/MSI and L8/OLI and to provide per-pixel uncertainty estimates traceable from assumed top-of-atmosphere (TOA) measurement uncertainty, making progress towards an important aspect of CEOS ARD target requirements. A set of observational and a priori constraints are developed in SIAC to constrain an estimate of coarse resolution (500 m) aerosol optical thickness (AOT) and total column water vapour (TCWV), along with associated uncertainty. This is then used to estimate the medium resolution (10–60 m) surface reflectance and uncertainty, given an assumed uncertainty of 5 % in TOA reflectance. The coarse resolution a priori constraints used are the MODIS MCD43 BRDF/Albedo product, giving a constraint on 500 m surface reflectance, and the Copernicus Atmosphere Monitoring Service (CAMS) operational forecasts of AOT and TCWV, providing estimates of atmospheric state at core 40 km spatial resolution, with an associated 500 m resolution spatial correlation model. The mapping in spatial scale between medium resolution observations and the coarser resolution constraints is achieved using a calibrated effective point spread function for MCD43. Efficient approximations (emulators) to the outputs of the 6S atmospheric radiative transfer code are used to estimate the state parameters in the atmospheric correction stage. SIAC is demonstrated for a set of global S2 and L8 images covering AERONET and RadCalNet sites. AOT retrievals show a very high correlation to AERONET estimates (correlation coefficient around 0.86, RMSE of 0.07 for both sensors), although with a small bias in AOT. TCWV is accurately retrieved from both sensors (correlation coefficient over 0.96, RMSE <0.32 g cm−2). Comparisons with in situ surface reflectance measurements from the RadCalNet network show that SIAC provides accurate estimates of surface reflectance across the entire spectrum, with RMSE mismatches with the reference data between 0.01 and 0.02 in units of reflectance for both S2 and L8. For near-simultaneous S2 and L8 acquisitions, there is a very tight relationship (correlation coefficient over 0.95 for all common bands) between surface reflectance from both sensors, with negligible biases. Uncertainty estimates are assessed through discrepancy analysis and are found to provide viable estimates for AOT and TCWV. For surface reflectance, they give conservative estimates of uncertainty, suggesting that a lower estimate of TOA reflectance uncertainty might be appropriate.

Abstract. The data assimilation technique is one of the important ways to reduce the uncertainty of atmospheric chemistry model input and improve the model forecast accuracy. In this paper, an ensemble optimal interpolation assimilation (EnOI) system for a regional online chemical weather numerical forecasting system (GRAPES_Meso5.1/CUACE) is developed for operational use and efficient updating of the initial fields of chemical components. A heavy haze episode in eastern China was selected, and the key factors affecting the EnOI, such as localization length-scale, ensemble size, and assimilation moment, were calibrated by sensitivity experiments. The impacts of assimilating ground-based PM2.5 observations on the model chemical initial field and PM2.5, visibility forecasts were investigated. The results show that assimilation of PM2.5 significantly reduces the uncertainty of the initial PM2.5 field. The mean error and root mean square error (RMSE) of initial PM2.5 for mainland China have all decreased by more than 75 %, and the correlation coefficient could be improved to more than 0.95. Even greater improvements appear in North China. For the forecast fields, assimilation of PM2.5 improves PM2.5 and visibility forecasts throughout the lead time window of 24 h. The PM2.5 RMSE can be reduced by 10 %–21 % within 24 h, but the assimilation effect is most obvious in the first 12 h. The assimilation moment chosen at 1200 UTC is more effective than that at 0000 UTC for improving the forecast, because the discrepancy between simulation and observation at 1200 UTC is larger than that at 0000 UTC, indicating the assimilation efficiency will be higher when the bias of the model is higher. Assimilation of PM2.5 also improves visibility forecast accuracy significantly. When the PM2.5 increment is negative, it corresponds to an increase in visibility, and when the PM2.5 analysis increment is positive, visibility decreases. It is worth noting that the improvement of visibility forecasting by assimilating PM2.5 is more obvious in the light pollution period than in the heavy pollution period, since visibility is much more affected by humidity during the heavy pollution period accompanied by low or extreme low visibility. To get further visibility improvement, especially for extreme low visibility during severe haze pollution, not only PM2.5 but also relative humidity should be simultaneously assimilated as well.
The impact of microphysical uncertainty conditional on initial and boundary condition uncertainty under varying synoptic control

Published: November 2022

Abstract. The relative impact of individual and combined uncertainties of cloud condensation nuclei (CCN) concentration and the shape parameter of the cloud
droplet size distribution (CDSD) in the presence of initial and boundary condition uncertainty (IBC) on convection forecasts is quantified using the
convection-permitting model ICON-D2 (ICOsahedral Non-hydrostatic). We performed 180-member ensemble simulations for five real case studies representing different synoptic forcing
situations over Germany and inspected the precipitation variability on different spatial and temporal scales. During weak synoptic control, the
relative impact of combined microphysical uncertainty on daily area-averaged precipitation accounts for about one-third of the variability caused by
operational IBC uncertainty. The effect of combined microphysical perturbations exceeds the impact of individual CCN or CDSD perturbations and is
twice as large during weak control. The combination of IBC and microphysical uncertainty affects the extremes of daily spatially averaged rainfall
of individual members by extending the tails of the forecast distribution by 5 % in weakly forced conditions. The responses are relatively
insensitive in strong forcing situations. Visual inspection and objective analysis of the spatial variability in hourly rainfall rates reveal that
IBC and microphysical uncertainties alter the spatial variability in precipitation forecasts differently. Microphysical perturbations slightly shift
convective cells but affect precipitation intensities, while IBC perturbations scramble the location of convection during weak control. Cloud and
rainwater contents are more sensitive to microphysical uncertainty than precipitation and less dependent on synoptic control.
Community identities under perturbation: COVID-19 and the r/digitalnomad subreddit
Authors: Pita Manuel , Ehn Karine , Dos Santos Thiago
Published: November 2022

Digital nomads (DNs) are hyper-mobile, location-independent workers whose practices blur traditional boundaries between labour, leisure, home and travel. They rely on digital tools to work and on computer-mediated communication to share knowledge and resources. Their resource-sharing culture is vital for self-efficacy and self-actualisation — two fundamental values that define the DN identity. Community identity is a constant social-semiotic construct mutually determined by (micro) interactions and the (macro) influence of collectively shared meanings and symbols. However, most of our understanding of community identity comes from structural and synchronic properties that often assume identity “exists” as an entity, separate from underlying collective dynamics. In this paper, we approach community identity diachronically, by introducing a quantitative typology that projects conversational timelines on two dimensions relevant to understanding the process of community identity construction: (a) the temporal orientation to the community core (or peripheral) conversation topics, and (b) interaction pattern anomalies. We cast three years of r/digitalnomad threads as a set of conversation topics, describing the interaction dynamics on these topics using the proposed typology. The central questions asked by this paper are whether there was a pre-pandemic stable community expression, and if so, how the COVID-19 pandemic may have perturbed it. Since lockdowns and travel restrictions impinged on fundamental DN values, the nature of the topics and interaction patterns that characterise the r/digitalnomad subreddit could have changed its character. We found a stable pre-pandemic balanced expression of core and peripheral conversation topics with regular interaction patterns. This identity expression was perturbed temporarily in the middle of the lockdown period when the community shifted focus to interactions about visa issues. As many countries began to re-open their borders around May 2021, a record-breaking number of interactions disrupted identity expression more profoundly. First, we observed constant interaction anomalies. Second, the community orientation revealed multi-factorial emergent issues, most of which revolved around conversations about what it means to be a DN, resource sharing and restrictions. We hypothesise that an influx of outsiders may have caused a clash of social norms and triggered a transformation of the DN identity that was still ongoing at the end of the studied period, in December 2021.

Published: November 2022

It is well established that elite sports performers encounter multiple stressors during their careers. However, limited research has specifically investigated developmental, organisational, and competitive transitional experiences of international junior elite athletes. Through the application of  Role Strain Theory (RST), this study extended the sport talent development literature by providing key insights into the experiences of five highly successful Great Britain (GB) junior international acrobat gymnasts, aged 14-17. It explored how they  simultaneously combined multiple sport, family and educational role demands during their pre-elite to elite transition and coped with these complex demands. Derived themes from semi-structured retrospective interviews identified a presence of chronic, but low level and manageable role strain during all transitional stages, which enabled positive acrobatic development, life satisfaction, physical and mental well-being and educational progress. All reported how severity and regularity of role strain, specifically overload and conflict, at times fluctuated intermittently during the early teenage years. It was at this point when increased role strain was reported to meet family commitments due to increased training and competition schedules. Challenges faced in maintaining healthy and compatible friendships, particularly with peers outside of acrobatics and school settings, were further sources of role strain during this time. Three key factors which regulated role strain were present in all participant narratives: early internalised acrobatic identity, acrobatic specialisation by very young age and social and tangible guidance from teachers and coaches in support of the athletes’ holistic development. Potential further research and limitations are discussed.

Introduction. Hypertensive disorders during pregnancy are one of the main causes of maternal mortality in the world. Both premature detachment of the normally located placenta, which led to massive bleeding on the background of placental insufficiency, according to the theory of placental ischemia, and disruption of compensatory mechanisms, leading to multiple organ failure, can lead to an unfavorable outcome. The pathogenesis of lung damage in preeclampsia is based on the activation of lipid peroxidation. Therefore, one of the components of complex therapy of severe lung damage may be the use of venovenous extracorporeal membrane oxygenation (ECMO), which is a method of extracorporeal support of gas exchange function in patients with life-threatening acute respiratory failure, accompanied by severe arterial hypoxemia and hypercapnia. The aim of the work is to demonstrate the possibility of using extracorporeal membrane oxygenation in the complex therapy of severe lung damage in a patient with multiple organ failure caused by severe preeclampsia. Materials and methods. A clinical observation of the nature of the course of multiple organ failure and lung damage in a laboring woman with severe preeclampsia is presented, her life history, diseases, diagnostic and treatment methods used are analyzed. Results and discussion. The described clinical case demonstrates the possibility of successful application of extracorporeal membrane oxygenation in combination with early renal replacement therapy, respiratory therapy and nutritional support in a patient with severe lung damage against the background of multiple organ failure caused by severe preeclampsia. Conclusion. It is necessary to use extracorporeal replacement techniques of vital functions replacement as early as possible in patients with severe lung damage against the background of multiple organ failure caused by severe preeclampsia.

Authors: Maia Raquel Tavares , Falcão Elaine de Sousa , Da Silva Luana Kelly Freitas
Published: November 2022

Introdução: A Residência Multiprofissional foi instituída através da lei 11.129. Constitui-se como uma modalidade de pós-graduação. Nesse contexto destaca-se no Ceará, o Programa de Residência Multiprofissional da Escola de Saúde Pública – ESP/CE. Autarquia vinculada a Secretaria de Saúde do Estado. A mesma conta com oportunidades para diversas profissões. Este estudo dará ênfase ao programa de residência em saúde mental. Estes profissionais residentes atuam dentro dos Centros de Atenção Psicossocial-CAPS, Unidades de Pronto Atendimento-UPA e Hospitais Psiquiátricos de Referência. Objetivo: Descrever as ações desenvolvidas por residentes em saúde mental durante a atuação em um hospital psiquiátrico de referência. Método: Trata-se de um estudo descritivo de abordagem qualitativa do tipo relato de experiência. Resultados e Discussões: A lei 10.216 dispõe sobre os direitos das pessoas portadoras de transtornos mentais e também redireciona o modelo de atendimento a essas pessoas. É um marco na história da luta antimanicomial. É importante enfatizar que o hospital de atuação das residentes ainda exerce “práticas” que remetem ao modelo asilar e manicomial que outrora era visto como “normal” na sociedade. Isto por que a rede de atenção psicossocial tem suas fragilidades fazendo com que hospitais psiquiátricos ainda sejam necessários. Conclusão: Conclui-se que os serviços de saúde como um todo ainda encontram dificuldades no manejo de casos relacionados à saúde mental. Situações que poderiam ser encaminhadas para a atenção especializada (Centro de Atenção Psicossocial-CAPS) acabam agravando-se devido à falta de tratamento adequado, e consequentemente, necessitando de uma internação hospitalar imediata pelo grau de complexidade, que são justamente os hospitais psiquiátricos.

The erosivity thing with inside the conventional soil loss equation (USLE) affords a powerful approach ofcomparing the erosive energy of rainfall. This study estimated the erosivity factorbased on monthly and yearly periodic rush rainfall data of Amritsar, Punjab State covering a period of 45 year from1971 to 2015using Lombardi system (EI = 1.03 Vd1.51). It was found that early arrived rainfall led high erosive index.The data of seasonal distribution of precipitation illustrated that the most ferocious erosion imminence inthe area can be anticipated in August, especially in the areas that arenât defended by foliage cover, whichmight be due to climatic change. The average periodic erosivity indicator for the megacity during theperiod of study was 744.6 MJ mm/ hr. The correlation between periodic erosivity indicator andaverageperiodic rush was expressed as Y = 0.0002x + 0.8873. The R2 of 0.79 shows that rush alone contributed 79 %of the corrosion threat within the study period. The knowledge of impact of rainfall on erosivity is essentialin soil erosion threat assessment and for soil and water conservation planning. The information on effect ofprecipitation on erosivity is important in soil disintegration threat evaluation and for planning of waterand soil conservation.

An experiment was conducted to study the effect of iron fortification in morphology, minerals and antioxidantcomposition of watercress under organic soilless culture for testing the possibility of increase in iron contentin its edible parts at Dept. of Horticulture, Sikkim University, Gangtok during 2017-2018. Plants weregrown in a solution of 500 g vermicompost and 5 g citric acid in trays filled with cocopeat +coarse perlite(1:1). The experiment was laid out under the protected condition. Four different concentrations ofFeSO4@0.2%, 0.3%, 0.4% and 0.5% were used. All the morphological parameters like leaf length, number ofleaves per plant, leaf thickness, plant height, plant fresh weight and plant dry weight showed significantincrease at 0.5% concentration of FeSO4 fortification. Minerals like Fe, Cu, Zn and Mn contentin plant werealso significantly increased at given concentration. In contrast, the maximum concentration of FeSO4 showedthe opposite effect on the antioxidant content in the watercress plant. Overall, the watercress plants grownin increased amount of FeSO4 media were luxuriant in their growth with increased number of essentialelements especially iron. Therefore, the findings suggest that FeSO4 can be used in the growing media foriron fortification in watercress with yield enhancement.

The present study aims to analyse the relationship among length, weight, condition factor (K), and relativecondition factor (Kn) of Pachypterusatherinoides (Bloch, 1794) with emphasis on seasonal variation of growthpatterns, productivity, stocks, and conservation in two contrasting ecosystems pond, and river in the PaschimMedinipur and Jhargram districts of West Bengal, India. The result reveals that the species showed allometricgrowth patterns in all seasons and did not strictly abide by the intended cube law. The regression parameter(b) values ranged from 1.98 to 3.13; the condition factor varied between 0.34 to 0.78; a relative conditionfactor ranged from 0.51 to 1.17 for P. atherinoides, in the study area. The average values of regression parameter(b), condition factor (K), and the relative condition factor (Kn) were highest during the post-monsoonseason. The regression coefficient (r2) values depict a strong relationship between the length and weight inboth habitats and all seasons. The Pearsonâs correlation indicates some positive and negative significantcorrelations among season, length, weight, condition factor, and relative condition factor in the study area (P<0.01 and P<0.05). The Post Hoc test represents a significant (P<0.05) seasonal relationship betweenlength, weight, condition factor, and relative condition factor. However, there is no significant habitatbasedrelationship between the same parameters. Therefore, the present findings will help fishery managersto develop effective methods for the sustainable management of P. atherinoides in their habitats.
THE ROLE OF CLIENT SATISFACTION IN BANKING SECTOR
Authors: Riak PhD Gabriel Alier , Bill Dut Bol Ayuel
Published: November 2022

According to existing definitions and approaches, customer satisfaction can be analyzed as a general/overall judgment that a customer makes after consuming a product or a service.  Customer satisfaction is perceived as “psychological state (feeling) appearing after buying and consuming a product or service (Merouane, 2009). Thus, customer satisfaction reflects “a pleasure resulting to product’s consumption, including under or over fulfillment level” (Hayes, 2012).  Customer satisfaction is closely connected with a company’s success possibility now and in the future. It is acknowledged that with higher customer satisfaction level, a company could retain its customers maximally and sustain competitive advantages as well as build up customer retention and loyalty gradually in the long run (Kotler, 2006). 

According to Chen and Yang, (2011), customer satisfaction has increasingly gained attention from different business fields. An increasing number of companies regard customer satisfaction as a standard to measure the performance of products or services and an approach to retaining their customers. In brief, customer satisfaction is the customers’ feelings of pleasure or disappointment derived from the performance of a certain product or service related to individual expectations Kotler, (2006). Consumers have respective judgments on their purchase or consumption experience from a product or service.
EFFECTS OF INFORMATION TECHNOLOGY ON BANKING SERVICE

Published: November 2022

The banking sector should anticipate challenges when adopting the use of technology so as to increase the possibility of success when using different forms of technology. Bradley and Stewart (2003), note that in the 21st century, many of the world banks use some form of technology. The research also found out that small banks have reaped great benefits from the emergence and use of technology. This conclusion is echoed by Vainio (2006) who concludes that the use of technology to provide services by small banks help them to gain a competitive advantage.

Poon (2008) notes that security and privacy in technological banking are the main source of dissatisfaction among banking customers and thus the influence the satisfaction of customers.However, advantages of technological banking that has yielded satisfaction from customers include better content provision of banking services, convenience, design and easier accessibility. E-banking success can also be affected by the banks speed in offering e banking services, the operational management of the e-banking services, the cost of using e banking for the customer and product features on the e-banking platform

Dans notre investigation, nous avons obtenu les résultats suivants :83,4% sont des femmes membres de tontines ; 83,3% de mariés ; 50% ont un âge compris entre 30 et 40 ans ; 38,5% ont plus de 5 personnes en charge ; 63,3% sont du niveau primaire ; 40% font le commerce comme activité principale ; 46,6% poursuivent dans les tontines l’objectif de se constituer un capital ; 30% sont du tribu Mamba-Kasenga ; 58,3% n’ont pas de difficultés des engagements entre les tontiniers ;66,6% préfèrent la contribution hebdomadaire ; 26,6% contribuent pour 2000 à 5000CDF ; les montants perçus par les membres vont de 56000CDF (26,6%) à 450000CDF (10%) ; en cas d’insolvabilité d’un membre, 66,6% préfèrent infliger une amande. Il nous revient donc de signaler que la pratique de tontines est une nécessité pour la survie des ménages. Il faut donc savoir comment l'utiliser, la moderniser et l'orienter non seulement vers la couverture des besoins sociaux mais également vers la création d'activités économiques.

Authors: Khan Md. Harunor Rashid , Yesmin Lovely
Published: November 2022

During the second half of the twentieth century there were several technological revolutions around the world, one of the most important being the supplanting of telecommunication over copper wires by optical transmission over glass fibers. Advances in optical fiber technology have been spectacular in the past 30 years but still there is more to come. Photonic fiber structures will create a radically new era of fiber optic communication. In this paper the rapid growth of optical fiber technology is reviewed and its possible new directions in communication are discussed.
Positivismo natural: entre la ontoética y la ética instrumental.
Authors: Munguía Ramos Zeus Adrián
Published: November 2022

Esta obra propone una visión jurídica innovadora que conjunta visiones filosóficas diferenciadas de la ética hasta arribar a una ética jurídica, que Munguía Ramos denomina positivismo natural. Es así como, a partir de visones jusnaturalistas de la onto-ética, que se aproxima a la positivización mediante la ética instrumental del consenso como herramienta legitimadora de casos concretos frente a derechos humanos no legislados. En ese sentido, el autor trata a los derechos fundamenta-les como aquello que comparte tanto un elemento objetivo de los contenidos básicos o bienes a determinar, como una subjetividad legitimadora que deriva en un consenso positivo de los mismos.
Angels and Anti-Pornography Feminists: A Comparative Analysis of Civilian Public Safety Organizations
Authors: Pomeranz Deborah
Published: November 2022

Late 1970s New York, rife with fear of crime and low trust in government to keep people safe, was a fertile ground for civilian public safety activism, which channeled people’s anger at the city’s situation into action to change it. The Guardian Angels and Women Against Pornography (WAP) were two of the best-known examples of this trend. Though rarely taken up together, this article places them in dialogue with one another in order to examine how racial, gender, sexual, and economic anxieties influenced the perception and possibilities of anti-violence community organizations at this time. I argue that while the predominately young, male, and nonwhite Angels were seen as belligerent, WAP’s adherence to the state’s social norms of acceptable female activism and sexual reformism facilitated their broader acceptance. The same social hierarchies that colored perceptions of the two organizations also shaped the available sources of partnerships, legitimacy, and funding, incentivizing both groups to undermine the most radically inclusive aspects of their missions in order to secure the resources they needed to continue operating most effectively.

The 2022 2nd International Conference on Economic Management and Corporate Governance (EMCG 2022) was held in Montreal, Canada from August 27 to 28, 2022 as a virtual conference due to the growing concerns over the coronavirus outbreak (COVID-19), and in order to protect the well-being of our attendees, partners, and staff.

EMCG 2022 brings together more than 90 national and international researchers from industry, government, and academia. We invited submissions of papers on all topics related to economic management and corporate governance. The conference provides networking opportunities for participants to share ideas, designs, and experiences on the future directions. The conference will feature a high-quality technical & experiential program dealing with a mix of traditional and contemporary hot topics in paper presentations and high-profile keynotes.

The conference model was divided into three sessions, including oral presentations, keynote speeches, and online Q&A discussion. In the first part, some scholars, whose submissions were selected as the excellent papers, were given about 10-15 minutes to perform their oral presentations one by one. Then in the second part, keynote speakers were each allocated 30-40 minutes to hold their speeches. We invited four professors as our keynote speakers. Their insightful speeches had triggered heated discussion in the third session of the conference.

The EMCG 2022 proceedings are a compilation of the accepted papers and represent an interesting outcome of the conference. All the papers have been through rigorous review and process to meet the requirements of international publication standard.

We would like to acknowledge all of those who supported EMCG 2022. The help and contribution of each individual and institution was instrumental in the success of the conference. We would like to thank the technical committee for its valuable inputs in shaping the conference program and reviewing the submitted papers.

Authors: Zhang Yanzhe
Published: November 2022

The novel Coronavirus pneumonia pandemic that began in early 2020 is still ongoing, resulting in great restrictions on international trade and heavy losses in the world economy. The shrinking income and rising unemployment rate have led to a serious decline in the market demand for luxury goods, and people's choice and pursuit of goods are more cost-effective and practical. In this era, the offline retail of luxury brands will inevitably be severely impacted. However, with the strong recovery of the luxury market in 2021, Especially in Chinese mainland, the luxury industry has unprecedented potential, so the luxury brands such as LV will usher in new challenges and opportunities. Even with the sudden outbreak of COVID-19 and the dismal sales of major brands in the past two years, LV has become one of the most resilient luxury brands under the pandemic by virtue of its brand image and marketing management. The measure it did in the post-pandemic era provides luxury brands with a reference. Therefore, the purpose of this study is the future prospects of the luxury industry and how LV will respond with this prospect, and also its future sustainable development under the pandemic. This paper analyses the future environment of the luxury industry in China and to provide some recommends to the transformation in various approaches to achieve sustainable development. The article will conduct a PEST analysis of the current luxury environment, and the port five-force analysis of the industry, aiming to explore and study the future development of luxury goods.
A Bubble Doomed to be Pricked Deconstructing the Chinese Real Estate Bubble
Authors: Guo Zhiyuan , Yan Linhang
Published: November 2022

China’s real estate housing boom has been a dreadful concern for economists worldwide. This paper analyzes the formation of the Chinese real estate housing bubble and investigates the factors that led to the bubble. Stimulated by the central government’s fiscal pressure, a redistribution of the tax revenues led to China’s local government’s “land financing” strategy, flaming the rise of housing prices. Moreover, due to the global financial crisis of 2008, the Bank of China proposed low-interest rates while the central bank increased credit availability to rejuvenate China’s economic state, which led to long-run damage. Furthermore, the expected traditional filial duty of Chinese parents to prioritize their children’s education as an investment and the obligation of owning a home for males before marriage also triggered the skyrocketing double-digit inflation rates. Finally, economists worry that the increased construction demand due to the rising urban population in the early 1970s will doom the new modern world as the population is now declining, followed by the low demand for housing in the future.
