Authors:   1Department of Computer Science, Caleb University Imota Lagos, Nigeria., B Adeyemi
Published: June 2022

Analyzing customer’s base for the purpose of retaining and attracting the most valuable customers still stands the main problem facing companies in this modern age. The process of conducting customer portfolio analysis (CPA) makes most existing customer relationship management systems (CRMS) lack ability to extract hidden information and knowledge from pool of data stored in customer databases or data warehouses, to conduct market segmentation due to the implementation techniques used. In this paper, a two-level hybrid approach that combines Self-Organizing Maps-Ward’s clustering denoted as (SOM-Ward) and decision trees data mining technique is proposed. The dataset used in this study were acquired from the loyalty card system, containing 1,480,662 customers, and sales information from several department stores. SOM-Ward clustering was used to conduct customer segmentation, by dividing the customer base into distinct segment of customers with similar characteristics and behavior. A Decision Tree was used to partition a large collection of data into smaller sets in order to identify the characteristics that can tell high-spending customers from low-spending ones. The result of the prediction performance of the decision tree shows that the overall accuracy of the model is 72.6%. 82.8% of the high spending customers are correctly classified, while only 62.4% of the low spending customers are correctly classified. This study revealed that the approach that combines SOM-Ward clustering and decision trees data mining technique outperforms SOM-based approach and Decision Trees individually for market segmentation, classification, and data exploration problems. Keywords: Customer relationship management (CRM), customer portfolio analysis (CPA), Self-Organizing Maps (SOM), Ward’s clustering, decision trees.

Information systems has continually experienced issues with acceptance and utilization of technologies. The anticipated benefits of the deployment of an innovation cannot be ascertained if the intended population do not adopt it. The gradual rise of the gig economy has captivated the attention of scholars to dig into this new concept of labor exchange and the accruable benefits. The gig economy also known as the “On-demand economy, sharing economy, platform economy, and digital economy” has known to have increase the work force through the various on-demand jobs rendered on the platform, which has increase end-user acquire goods and services from providers through apps on smartphones and web application. The platform has virtually come to replace how they would go through the trouble of requesting for services and as such found the use of the platform to be a substitute to how they request for services. It was however established from literature that very limited research has been conducted on the gig economy and facilitating factors for the gig workers and organization were the focus of existing research thus paying little or no attention to the end-users. This paper proposed a study that seeks to understand the nature of gig economy and the factors that drives end users intention to maximize and utilize the gig economy from a developing country context (Nigeria).

Authors: Johar Dheeraj , Sharma Dilip , Yadav Harekrishna , Patel Satyanarayan
Published: June 2022

In the present work, a pebble bed thermal energy storage (PBTES) system is developed to utilize the waste energy from engine exhaust. The developed PBTES is integrated with an electric dynamometer coupled stationary Diesel engine for experimental investigation. The engine performance is compared with and without integration of the PBTES system. The 60-75% of energy can be stored in the fabricated system during the charging process at various load conditions. It is found that nearly 11-15% of engine fuel energy can be saved using this storage system considering the charging process. Heat recovery/discharging from PBTES shows that 6-8.5% of fuel primary energy can be saved. The system combined (engine+PBTES) efficiency varies from 11-38% at different load conditions. The highest exergy saved is obtained as 3.32% when a 3 kW load is applied. The developed system can be easily used for domestic or industrial use space heating or hot fluid requirements.

Published: June 2022

Thermoacoustics offer alternative solution for cooling needs where a method that is safer to environment is used. The thermodynamic process that needs to be completed by using interaction between inert gaseous and porous material must be made efficient so that the system works properly. This paper reports numerical and experimental investigations of the use of several porous material in air at atmospheric pressure to provide cooling effect. Experimental investigation was also conducted by using cheap and abundant materials as the porous media. Results were collected at two different frequencies and with two different stack lengths. The study showed that thin-walled honeycomb porous structure made of polycarbonate offers the best temperature for thermoacoustic cooler with air at atmospheric pressure. The best COP of 4.73 was recorded. Disparity between numerical and experimental results is expected to be the result of losses that need to be carefully addressed in the future especially when long stack is used in the system.

Published: June 2022

Objectives

To evaluate the accuracy and reliability of a fully automated landmark identification (ALI) system as a tool for automatic landmark location compared with human judges.

Materials and Methods

A total of 100 cone-beam computed tomography (CBCT) images were collected. After the calibration procedure, two human judges identified 53 landmarks in the x, y, and z coordinate planes on CBCTs using Checkpoint Software (Stratovan Corporation, Davis, Calif). The ground truth was created by averaging landmark coordinates identified by two human judges for each landmark. To evaluate the accuracy of ALI, the mean absolute error (mm) at the x, y, and z coordinates and mean error distance (mm) between the human landmark identification and the ALI were determined, and a successful detection rate was calculated.

Results

Overall, the ALI system was as successful at landmarking as the human judges. The ALI's mean absolute error for all coordinates was 1.57 mm on average. Across all three coordinate planes, 94% of the landmarks had a mean absolute error of less than 3 mm. The mean error distance for all 53 landmarks was 3.19 ± 2.6 mm. When applied to 53 landmarks on 100 CBCTs, the ALI system showed a 75% success rate in detecting landmarks within a 4-mm error distance range.

Conclusions

Overall, ALI showed clinically acceptable mean error distances except for a few landmarks. The ALI was more precise than humans when identifying landmarks on the same image at different times. This study demonstrates the promise of ALI in aiding orthodontists with landmark identifications on CBCTs.

Objectives

This study collected and analyzed clinical data regarding the repair of dental restorations in patients treated in the clinics of a dental school over 10 years.

Methods and Materials

Data related to repair procedures for permanent tooth restorations were extracted from the digital dental records system and filtered according to year (January 1, 2008, to December 31, 2017), age (<30, 30–60, >60), tooth group, and dental surfaces. Data were analyzed with descriptive statistics in terms of the absolute and relative frequency, and chi-square tests (95% confidence) were used to compare the frequency of repairs between years, age, tooth, and dental surfaces.

Results

A total of 48,915 dental records were accessed by searching for general restorative procedures, of which 1,408 were repairs of dental restorations on permanent teeth. The number of repairs per year increased over the period assessed, and there was a significant increase in the years 2016 and 2017. Individuals aged between 30 and 60 years received the largest number of repairs, with significantly more repairs than the other groups. Regarding the tooth group and surface, the canines and the incisal and lingual surfaces received the least number of repairs.

Conclusions

The number of repairs increased over the study period. When comparing frequencies between groups, those belonging to the 30- to 60-years of age group received more repairs; the least repaired surfaces were the lingual and the incisal.

Published: June 2022

Objective

To compare the efficacy, color stability, and tooth sensitivity (TS) of combined bleaching, using a modified protocol with at-home bleaching.

Methods

Eighty participants were randomized into two groups. In the combined group, a desensitizing gel was applied (10 minutes) prior to in-office bleaching (35% hydrogen peroxide (H2O2), 2×15 minute applications) and at-home bleaching (4% H2O2, 2×30 minutes for 21 days) started the next day. In the at-home group, only the at-home bleaching was performed. Color was recorded at the beginning and postbleaching with two scales (VITA Classical and Bleachedguide) and Easyshade spectrophotometer. The TS was recorded daily with a 0–10 visual analogue scale (VAS) and five-point numeric rating scale (NRS).

Results

A 40% lower risk (RR=1.4; 95% CI 1.1–1.9) was observed in the at-home group. Higher color change and intensity of TS [mean difference 2.3 (95% CI 1.3–3.3) in the VAS] was observed in the first week for the combined group. After the end of the protocol, a bleaching degree was detected for both groups, with no significant difference between both groups (p>0.05).

Conclusion

The combined group produced a slightly higher degree of color change than at-home bleaching but with a higher risk and intensity of TS.

Effects of the Human Development Index on COVID-19 Mortality Rates in High-Income Countries
Authors: Zhou Lihui , Puthenkalam John J.
Published: June 2022

The coronavirus disease (COVID-19) pandemic has caused a huge loss of life and impaired public health worldwide. The finding that countries with high human development indices (HDIs) is associated with higher death rates during COVID-19 reported in earlier research is confusing. To clarify this significant problem, we explored the correlations and associations between the COVID-19 mortality rate and HDI based on updated data (until April 1, 2022) in 41 high-income countries across the world. The outcomes demonstrate: (a) a strong negative correlation between COVID-19 mortality rate and HDI; and (b) a significant (p = 0.013) negative association between COVID-19 mortality rate and HDI after controlling for health heterogeneities including aging population, full vaccination rate, GDP per capita, UHC, out-of-pocket burden, and stringency index. This paper concludes that reductions in the COVID-19 mortality rate depend to a great extent on the enhancement of human development capacity. Therefore, to better protect global public health, improving human development capacity should be a vital priority for all countries, whether in the present or in the future.

Published: June 2022

The present work proposes to identify the challenges promoted by the technological evolution and demands of the development of Tax Governance, here understood as a vertical of Corporate Governance, so that it is dedicated to transposing and adapting teachings and practices of Corporate Governance to the area of Administration and Tax Management. For that, the methodological tool of the case study was used, adopting as a specific object of examination an important brazilian economic agent in the civil construction segment. The research carried out had a qualitative bias, using bibliographic research and documental research. The results achieved allowed us to verify: negative influence between management structure and parameters of corporate and tax governance, even in privately-held companies; good business management and operation practices coincide with the administration and operation of taxes, which makes it impossible to dissociate corporate and fiscal governance; tax governance was analyzed from a multidisciplinary perspective, observing changes in the process and focusing on results, supported by the pillars of compliance, equity, transparency and accountability; and the special Brazilian scenario, which combines a high tax burden, multiple taxes and difficulties in fulfilling ancillary obligations, requires efforts to structure a business, train people and invest in technological infrastructure so that the company reaches satisfactory levels of work in the Tax Governance area.

Published: June 2022

La utilización de agregados reciclados provenientes de residuos de construcción y demolición (RCD) en nuevas obras civiles se considera el camino hacia la sostenibilidad. Esta investigación presenta la posibilidad del uso de agregado grueso reciclado (AGR) y agregado grueso tratado (AGT) de concreto en la elaboración de concretos autocompactantes (CAC). Para este propósito, dos métodos de tratamiento se realizaron a los AGR, uno de los tratamientos fue mediante desgaste mecánico en un molino de bolas y el otro fue mediante la  inmersión en una solución acida (H2SO4) combinado con el desgaste mecánico. Para investigar el efecto de los AGR tratados sobre las propiedades mecánicas de los CACs, diferentes niveles de reemplazo (0%, 20% 40% y 100% en volumen) de agregado grueso natural (AGN) por AGR y AGT se realizaron. En estado fresco se evaluó capacidad de flujo, capacidad de paso y capacidad de llenado mediante el flujo de asentamiento con cono de Abrams, embudo en V y caja en L; y en estado endurecido se realizaron pruebas de resistencia a la compresión, tracción indirecta y flexión a los CACs. Los resultados muestran que los CAC con AGR presentaron una disminución en el desempeño de las propiedades en estado fresco y endurecido debido a la presencia del mortero adherido en este tipo de agregados, sin embargo, su trabajabilidad se encontró dentro de los parámetros establecidos por la EFNARC. Las propiedades mecánicas de los CAC con AGT presentaron un mejor desempeño en comparación a los CAC con AGR, debido al retiro del motero adherido mejorando la resistencia a la compresión todas las mezclas. Además, los CAC con AGT mostraron mejoras en las propiedades de permeabilidad presentando una reducción de porosidad de hasta un 6,06%.

Autobiography vs History: “Dialectics of Life” by S.M. Shakhray
Authors:   Lomonosov Moscow State University, Belousova Evgeniya , Kholikov Alexey ,   Lomonosov Moscow State University
Published: June 2022

The review is an analytical review of the ego-documentary text, which opens a new series “90s: Personalities in History”. The authors paid special attention to the choice of S.M. Shakhray of a flexible narrative strategy that allowed him to recreate a picture not only of the “dashing nineties” in our country, but also to go beyond these spatial and chronological coordinates. Research interest is also attracted by the concept of understanding the past as an experience of self-knowledge: the versatile hobbies of the memoirist allow him to talk about politics and jurisprudence, philosophy and fiction. The reviewers highly appreciated the directness and uncompromisingness of S.M. Shakhray when creating images of “controversial” historical figures (B.N. Yeltsin, B.E. Nemtsov, A.A. Sobchak, Ye.T. Gaidar), the absence of “court” reverence in stories about meetings with high-ranking persons (Elizabeth II, Prince Charles, R. Nixon, etc.). The book is intended for a reader who is ready to see not a black and white picture, but a multicolored and voluminous reality of the recent history of his country.
An Exploratory Study on the Emotional Climate within Family Firms: The Impact of Emotional Dissonance
Authors: Vandekerkhof Pieter , Hoeks Laura , Claus Brent
Published: June 2022

This study focuses on the emotional climate of family firms. In particular, we highlight the expression of emotions by emphasizing the phenomenon of emotional dissonance within these firms. Emotional dissonance, a person-role conflict, originates from the discrepancy between expressed and experienced emotions. Additionally, we look into the role of the (non)family status of the CEO and the generational phase of the firm in the occurrence of the emotional climate. Research on emotions within firms has steadily increased over the years, although almost always neglecting family firms. This is a remarkable observation given the preeminence of family firms in the worldwide economy and the overlap between business and family these firms are confronted with. Through an in-depth qualitative study, we unravel both the impact of family firms’ emotional climate and the facets that contribute to this climate.

Authors: Chen Chi-Hui , Shih Chih-ming
Published: June 2022

In the context of coronavirus (COVID-19) pandemic, large-scale events have been forced to stop as well as movement of people between cities. At Daxi in Taoyuan, Taiwan, there is an event that lasts for over a century, Puji Temple Annual Celebration of Saintly Emperor Guan’s Birthday, held every summer on June 24 of the lunar calendar. It is not only registered as Taoyuan City’s intangible cultural heritage but also considered as the second Chinese New Year for local people. In order to express gratitude to Saintly Emperor Guan for his blessing, the local groups ‘She-Tou’, residents, shopkeepers and volunteers make a great effort on the preparations before the celebration. Local people who at the time do not live in Daxi because they are studying, working or after marriage are living in other cities would also come back to the town on this day. This traditional and cultural event bred from belief has become a mechanism of community cohesion and has shaped Daxi’s unique sense of place. Unfortunately, the traditional pilgrimage of the celebration in 2021 has been paused due to the pandemic situation. However, thanks to the long-term collaboration and participation of the local museum, the ritual of faith can continue in a new way. This article takes the DaxiDaxi “Lord Guan Online” website and its Facebook page as an example. By analysing how the Daxi Wood Art Ecomuseum interprets the traditional celebration and its culture in a digital way, we try to explore the possibility of digital tools as a powerful medium for connecting people and people and place during the pandemic period.
Modeling consumer behavior – Psychological paradigm
Authors: Anghel Mihai Alin
Published: June 2022

Modeling consumer behavior can be explained in the context of specific paradigms: sociological, psychological, cultural, neurocognitive, anthropological, and economic. With the discoveries in the field of neuroscience, the perspective of over-explaining consumer behavior is heading more toward cognitive neuroscience. The research in neurophysiology has succeeded in explaining the interpsychic processes and in the creation of multiple theories which are trying to determine the cause of human organism reaction to different external stimuli. The current scientifical challenges can be found especially around neuropsychology which is attempting to explain how the human brain works and which are the sections that influence the behavior. The research from neurobiology mentions the fact that at the core of buying purchases is a neurophysiological layer.

Published: June 2022

Severe pain is a major problem in the early postoperative period after open major upper gastrointestinal surgery. This study aimed to assess the efficiency of rectus sheath block with catheters placed through open access into the retromuscular space in providing effective pain relief. A prospective study was done at Rīga East University Hospital, Latvia. Thirty-nine patients with open gastrectomy were allocated into two groups: 21 patients in the block group and 18 patients in the control group. In the block group, at the end of the operation, two catheters were inserted into the retromuscular plane under the m. rectus abdominis through the open access (using a specially invented technique). After surgery, patients in the block group received continuous 0.125% (10–12 mg/h) bupivacaine infusion through rectus sheath catheters for 72 hours. Patients in the control group received standard postoperative analgaesia. The results showed that postoperative pain at rest was significantly lower in the Block group than in the control group at 48-hour and 72-hour intervals after surgery. Pain on movement in the block group was significantly lower than that in the control group at all postoperative times: at 24, 48, and 72 hours. The median fentanyl requirement range in the postoperative period was significantly lower in the block group (0.5 (0–1.25) mg) than in the control group (2.0 (1.0–3.25) mg (p = 0.001)). Continuous retromuscular rectus sheath infiltration of 0.125% bupivacaine through a rectus sheath catheter after open gastrectomy provides effective postoperative analgaesia in the early postoperative period and significantly reduces opioid consumption.

Published: June 2022

Inherited peripheral neuropathies (IPN) are a clinically and genetically heterogeneous group of disorders. The most common IPN is Charcot-Marie-Tooth (CMT) disease. Here we describe IPN clinical variability and diagnostic characteristics in the Latvian population. A total of 101 patients were enrolled in the study. Genetic testing consisted of PMP22 copy number analysis and whole-exome sequencing (WES). Clinical assessment comprised CMT Neuropathy Score version 2 (CMTNSv2), CMT Examination Score, pain, anxiety and memory/cognitive ability testing. The diagnostic yields for PMP22 copy number detection and WES were 45.8% and 77.8%, respectively. Disease severity assessment indicated high clinical heterogeneity, with CMTNSv2 scores ranging between 0 and 33. More than one-third of patients reported pain, and it was found to be significantly more common in patients with at least a mild anxiety level. From the initial development of symptoms, on average, it took more than 13 years for a diagnosis of IPN to be confirmed. This study updates the IPN genetic and clinical profile of the Latvian population and demonstrates the presence of a high level of heterogeneity. The time to diagnosis for IPN patients needs to be improved by employing multiplex ligation-dependent probe amplification initially followed by WES.

We analysed the age- and sex-specific incidence, disease-stage distribution, treatment modalities, and survival of patients with hepatocellular carcinoma (HCC) in Latvia from 1997 to 2017. Retrospective data from the Cancer Registry of Latvia identified 692 men and 427 women aged >19 years who were diagnosed with HCC, confirmed by autopsy, morphological, radiological, or clinical examinations. The total incidence of HCC increased from 2.63 to 3.75 cases per 100 000 person-years in 1997–2007 and 2008–2017, respectively. It was higher in men and increased with age. Two-thirds (65.9%) of patients were diagnosed with stage IV HCC. Overall, 935 patients died during follow-up. The survival rate was low: 32.5% and 22.2% of patients survived for 6 months and 1 year after diagnosis, respectively. Male sex, older age, and advanced stage at diagnosis were associated with poor prognosis. The proportion of radically treated patients was higher, and survival was better, in the period 2008–2017. Our epidemiological analysis of HCC over 20 years shows that the overall incidence of HCC has been increasing in Latvia since 1997; however, it is similar to that of other European countries. Advanced stage at diagnosis results in a low proportion of radically treated patients and poor overall survival.

The aim of the present study was to evaluate the effect of different levels of mineral nutrient availability on development and physiological performance of several common indoor ornamental plant species (Anthurium sp., Chlorophytum comosum, Epipremnum aureum, Plectranthus fruticosus, Spathiphyllum sp., and Tradescantia pallida) cultivated in hydroponics with potential use in active botanical biofilter systems. Plants were grown in expanded clay granules at four levels of mineral nutrient availability provided by two types of commercial mineral fertiliser. The growth stimulative effect of increased mineral nutrient availability depended on plant growth rate, with a lower effect on slower growing species. The need for nutrients increased in the order Anthurium < Spathiphyllum < Epipremnum < Chlorophytum < Tradescantia < Plectranthus. Tissue water content showed pronounced differences between various plant species as well as between plant organs. For several species, increase in mineral nutrient availability resulted in a significant increase in tissue water content. Chlorophyll fluorescence analysis showed that indoor plants can successfully adapt to low and moderate mineral fertiliser levels with balanced individual nutrient rates, without negative consequences to photochemistry of photosynthesis. Consequently, indoor plants can be cultivated at a relatively low concentration of mineral nutrients for optimum utilisation in active botanical biofilter systems.
On a Class of Lacunary Almost Newman Polynomials Modulo P and Density Theorems
Authors: Dutykh Denys , Verger-Gaugry Jean-Louis
Published: June 2022

The reduction modulo p of a family of lacunary integer polynomials, associated with the dynamical zeta function ζβ
(z)of the β-shift, for β> 1 close to one, is investigated. We briefly recall how this family is correlated to the problem of Lehmer. A variety of questions is raised about their numbers of zeroes in 𝔽
p
and their factorizations, via Kronecker’s Average Value Theorem (viewed as an analog of classical Theorems of Uniform Distribution Theory). These questions are partially answered using results of Schinzel, revisited by Sawin, Shusterman and Stoll, and density theorems (Frobenius, Chebotarev, Serre, Rosen). These questions arise from the search for the existence of integer polynomials of Mahler measure > 1 less than the smallest Salem number 1.176280. Explicit connection with modular forms (or modular representations) of the numbers of zeroes of these polynomials in 𝔽
p
is obtained in a few cases. In general it is expected since it must exist according to the Langlands program.

The success of an individual to become an entrepreneur is highly dependent on the entrepreneurial interest that the individual has. The role of entrepreneurs is needed by a country because it also determines the success of national development. The purpose of the study was to determine the effect of entrepreneurship education, motivation and the environment on students' interest in entrepreneurship at universities in Denpasar City. This research is an associative study or research and is carried out on students who come from colleges equivalent to private universities in Denpasar City. The research population is students from six universities in the city of Denpasar, with a total of 225 students as respondents. Collecting data using a questionnaire distributed online. The method of data analysis is descriptive and inferential. The results or research findings are the positive and significant influence of entrepreneurship education on motivation and interest in entrepreneurship. The environment has no significant effect on motivation, but has a positive and significant effect on interest in entrepreneurship.

The adsorption capacity of three eggshell bioadsorbents was evaluated to remove contaminants from raw leachate. Optimal conditions for the removal of suspended solids, color, and organic compounds, as COD, were achieved by batch experiments with three levels of pH and absorbent concentrations. Kinetic studies and isotherms were developed to understand the behavior of COD removal by the bioadsorbents. The chemical and physical characterizations indicate the leachate used in the present study had characteristics between mature and intermediate leachates. The optimal adsorption conditions were pH 2.0 and 1.0 gram (0.5 g/L) of adsorbent. Adsorbent M showed the best adsorption capacities, removing 99.06% (1446 NTU) of turbidity, 86.25% (4140 UPt-Co) of color and 54.56% of COD (1530mg/L). The data obtained through the kinetic and isothermal tests were better fitted to the pseudo first order and Langmuir models, with an equilibrium adsorption capacity (Qe) of 139 mg of COD/g of adsorbent and a specific speed of 1.51 min-1.
Filosofía, belleza funcional y sentir cotidiano en el arte conmemorativo
Authors: Carrasco Barranco Matilde
Published: June 2022

Se denuncia que la filosofía del arte no ha atendido suficientemente ni a la funcionalidad que define a muchas obras, y a géneros como el arte conmemorativo, ni a las emociones que generan: un sentir cotidiano considerado inapropiado como respuesta al arte. Se argumenta que el concepto filosófico (autónomo) de arte lo impide. El reciente debate sobre la necesidad de apreciar una «belleza funcional» insiste en ello. Sin embargo, los análisis de Arthur Danto sobre el arte conmemorativo permiten conciliar un concepto filosófico de arte con su posible funcionalidad y con la afectividad que despierta en la gente corriente.
Revolución, arte público mexicano y la Liga de Escritores y Artistas Revolucionarios (1934-1938)
Authors: Hernández del Villar Sureya Alejandra
Published: June 2022

En la primera mitad del siglo XX, el arte público fue un tema central en las discusiones respecto a cómo debía ser el arte mexicano. A menudo, el debate apuntaba a la articulación entre el arte y los artistas con la “lucha de los obreros”. Ambos actores eran considerados protagonistas y agentes de una revolución en marcha, codo con codo en la misma lucha. Este artículo pretende describir y analizar algunas resoluciones de arte público propuestas por la Liga de Escritores y Artistas Revolucionarios (LEAR), una organización de izquierda y antifascista que incluía a artistas e intelectuales de diversas disciplinas. Mi objetivo es mostrar cómo la LEAR propuso alternativas de arte público, proyectado como una herramienta útil para los trabajadores a partir un programa enfocado en la colaboración a través del arte.
Onetti, entre Lavanda y Montevideo. (La construcción análoga de la ciudad)
Authors: Lubelski Aarón
Published: June 2022

La configuración del espacio en la obra del escritor uruguayo Juan Carlos Onetti recuerda ciertos sistemas constructivos aplicados en el diseño urbano, como el concepto de ciudad análoga acuñado por el arquitecto Aldo Rossi, según el cual el espacio urbano puede ser construido a través de la superposición de distintas posibilidades arquitectónicas, tanto imaginarias como reales, las cuales permiten la creación de una nueva realidad aún no existente. Aplicando dicho concepto urbano, este artículo analiza la construcción del espacio en Dejemos hablar al viento, una de las obras de la madurez de Onetti, publicada en 1979. Lavanda, espacio urbano que ambienta la trama de la primera parte de la obra, es configurada a través de referencias que remiten a la capital uruguaya, Montevideo, que junto con topónimos adicionales de referencia ambigua, establecen entre ambas una relación análoga, modelo constructivo que ofrece nuevas perspectivas de lectura.
