Authors: - Laurence - , Gumulya Devanny , Sembel J. Sandra , Ginting Magdalena Lestari
Published: January 2022

Pariwisata merupakan salah satu kontributor penting dalam menunjang perekonomian suatu negara. Penelitian ini menitikberatkan pada kajian kunjungan wisatawan asing ke Jepang dengan mengambil data jumlah wisatawan yang berkunjung dan jumlah pengeluaran wisatawan untuk kategori akomodasi, hiburan, makanan dan minuman, belanja, transportasi, dan lain-lain. Pada studi yang dilakukan sebelumnya tidak terdapat pengelompokan negara untuk berbagai macam pengeluaran ini, sehingga posisi penelitian ini adalah mengisi kekosongan tersebut dengan melakukan pengelompokan negara berdasarkan pengeluaran turis. Selain itu, tujuan studi ini juga membuat model peramalan dengan menggunakan metode ARIMA yang mengakomodasi tren dan musim. Data yang terdiri dari enam jenis pengeluaran direduksi menjadi 2 dengan nilai variansi yang dijelaskan sebesar 83,84%. Hasil pengolahan data menunjukkan 2 kelompok negara turis berdasarkan pengeluarannya. Dua grup tersebut terdiri dari 8 negara anggota OECD dan 12 negara non OECD. Turis yang berasal dari negara yang tergabung dalam OECD memberi memainkan peranan penting dalam perekonomian dunia dengan kontribusi sebesar 50,5 % dari total pengeluaran turis dunia. Kualitas gugus dikategorikan baik dengan rata-rata koefisien siluet dan nilai kohesi 0,56. Pengelompokan ini dapat digunakan sebagai dasar untuk melakukan studi perilaku konsumen setiap negara. Metode peramalan menggunakan ARIMA dapat digunakan dengan memasukan elemen tren dan musim ke dalam model. Nilai R2 pada model peramalan menunjukan hasil yang baik pada sebagian besar data turis dari 20 negara. Model ARIMA musiman ini dapat dipertimbangkan sebagai model untuk meramalkan jumlah turis yang datang.

HYDRATE MITIGATION FOR DEEP WATER AND LONG DISTANCE PIPELINE – FLOW ASSURANCE APPROACH
Authors: Karono Riesto Mundi
Published: January 2022

The existence of gas hydrates is well known in the oil and gas production industry. The components are dominated by methane and naturally occur in deep marine sediment along continental margins. Although hydrates may be of potential benefi t both as a hydrocarbon resource and as a mean of storing and transmitting natural gas, traditionally their presence is considered to be an operational and a safety problem. They can form at the pressures and temperatures found in natural gas and oil pipelines causing blockages, especially when temperature falls signifi cantly, such as when closing in a well or fl owing gas through a choke. This could deliver a serious potential problem for oil and gas offshore production either for its equipment or personnel. Besides the variation of gas rate to avoid hydrates forming, currently there are two methods that have been used widely to prevent hydrates formation in production pipelines - thermal insulation and chemical inhibitor. Each method has its own benefits. PIPESIM software application can be used to evaluate both mitigation methods and to then fi nd which is the best scenario based on lowest cost, shortest period of application and less adversity.
THE DEGRADATION OF THE PROTECTIVE SCALE ON BINARY FeCr ALLOYS (Fe-2.25Cr, Fe-10Cr, Fe-18Cr AND Fe-25Cr) IN CO2 AND IN CO2 + H2O ENVIRONMENT AT 600oC
Authors: Pujilaksono Bagas
Published: January 2022

The oxidation behaviour of the binary alloys Fe-2.25, Fe-10Cr, Fe-18Cr and Fe-25Cr in dry and wet O2 at 600oC is investigated by isothermal exposures of carefully polished samples for up to 168 hours. The oxidized samples are investigated gravimetrically and the oxides formed are studied by X-ray diffraction. X-ray photoelectron spectroscopy is used for depth pro􀂿 ling of the thin oxides. The scale surface is imaged by SEM. Cross sections through the scale are analyzed by SEM/EDX for imaging and for measuring the chemical composition. The oxidation behavior of the four FeCr alloys is intermediate between those of iron and chromium. Fe-2.25Cr oxidizes in a way similar to iron in both environments, forming a poorly protective scale consisting of FeCr spinel at the bottom, magnetite in the middle and a hematite cap layer. In dry O2, Fe-10Cr, Fe-18Cr and Fe-25Cr form a thin and protective (Fe,Cr)2O3 oxide similar to the chromia 􀂿 lm formed on pure chromium. In wet O2, Fe-10Cr, Fe-18Cr and Fe-25Cr initially form the same kind of protective oxide 􀂿 lm as in dry conditions. After an incubation time that depends on alloy chromium content, all three alloys go into breakaway oxidation and form thick, poorly protective scales similar to those formed on Fe-2.25Cr. Breakaway oxidation in wet O2 is triggered by the evaporation of CrO2(OH)2 from the protective (Fe,Cr)2O3 oxide.

Authors: Sari Cut Nanda , Sativa Tyas Putri , Moersidik Setyo Sarwanto
Published: January 2022

Oil spills, in both aquatic and terrestrial environments, are very detrimental to people and the environment due to hydrocarbon compounds that are contained in oil which are not only be harmful for the balance of the ecosystem and the environment but also carcinogenic to humans and animals. Therefore remediation needs to be done. One of the methods is by using a combination of microorganisms and plants. The aim of this research is to analyze the in􀃀 uences between several different treatments that are applied for TPH and BTEX removal in the process of remediation. In this research, bioremediation was conducted by using four different treatments which are: by adding compost (C), plants and compost (P), microorganisms and compost (B), and compost, plants and microorganisms (BP), to soil with oil content of 5% and 10%. The following test results of TPH in soil contaminated with 5% oil content are: 2.10% (C); 1.31% (B); 1.66% (P); and 0.68% (BP). The TPH test results in soil contaminated with oil content of 10% are: 3.30% (C); 2.54 (B); 3.91% (P); and 3.31% (BP). The highest percentage of TPH degradation in contaminated soil of 5% oil content was found in BP treatment (87.1%), while in the contaminated soil of 10% oil content the largest TPH removal percentage is by the treatment of adding bacteria (B) which is 76.19%. BTEX removal percentage in 5% oil contaminated soil in BP treatment is 68.35% while in 10% oil contaminated soil with B treatment the removal percentage is 84.91%. Based on statistical tests, both on contaminated soil with 5% and 10% oil content, TPH degradation signi􀂿 cantly affects the pH value as p 0.05 but TPH degradation does not affect temperature values as p 0.05.
EFFECT OF OPTIMUM SALINITY?ON MICROEMULSION FORMATION TO ATTAIN ULTRALOW INTERFACIAL TENSION FOR CHEMICAL FLOODING APPLICATION
Authors: Alli Yani Faozani , Tobing Edward ML
Published: January 2022

Microemulsion formation in surfactant solution has a major influence on the success of chemical injection techniques, and is one of the enhanced oil recovery methods. Its transparent and translucent homogenous mixtures of oil and water in the presence of surfactant have an ability to displace the remaining oil in the reservoir by reducing interfacial tension between oil and water. In this study, the effect of surfactant solution salinity on the formation of microemulsion and its mechanism to reduce the interfacial tension between water and oil from X oil field in Central Sumatera were carried out through compatibility observation, phase behaviour test and interfacial tension measurements in a laboratory. The results showed that microemulsion formation depends on the salinity of aqueous phase associated with different surfactant solubility by altering the polar area of surfactant. The optimum salinity was obtained with the addition of 0.65% Na2CO3 in which microemulsion was formed and the solubilization ratio of oil and water were equally high. At this condition the ultralow interfacial tension was around 10-3 dyne/cm and enabled improved oil recovery in mature oil fields after waterflooding
SHALE AS HYDROCARBON RESERVOIRS
Authors: Junira Adi , Wibowo Andy Setyo
Published: January 2022

Nowadays, shale plays a role as hydrocarbon producing rock. Due to its unusual properties as a reservoir, shale is classified as an unconventional reservoir. Among these properties are the relatively low permeability (0.1 mD or less) and the relatively low porosity (10% or less). The relatively low permeability had been the main obstacle to extracting the hydrocarbon held by shale in the past. Nevertheless, the technologies of horizontal drilling and hydraulic fracturing have proven to be effective in stimulating a liquid flow in low permeability reservoirs such as a shale layer which has encouraged the hydrocarbon exploration in the oil shale industry. This paper is intended to provide an overview of technologies implemented in the current oil shale reservoir along with their challenges summarized from available sources in a concise manner.
THE IMPORTANCE OF GEOLOGICAL AND HYDROGEOLOGICAL KNOWLEDGE IN JUSTIFYING PORE PRESSURE PREDICTION: THE CASE STUDY OF THE PECIKO FIELD, LOWER KUTAI BASIN
Authors: Ramdhan Agus M
Published: January 2022

One significant factor affecting pore pressure prediction is choosing a method of calculation. If we choose the inappropriate method, the result may not refl ect not only pore pressure condition in an area, but also geological processes operating in the whole basin. In this research, two methods are applied to wireline-based pore pressure calculation in the Peciko Field: the Eaton Method and the Soil Mechanics Method. The results of the calculation show a signifi cant difference between these methods. The Eaton Method resulted in reservoir-shale pressure discrepancy (by over-predicting the reservoir pressure) at shallower depth, and reservoir-shale pressure equilibrium at depth. On the contrary, the Soil Mechanics Method resulted in reservoir-shale pressure equilibrium at shallower depth and an under-predicting at depth. It seems that, in terms of processes operating in this fi eld which affect pore pressure regimes, i.e. lateral reservoir drainage and rapid mud-dominated deltaic sedimentation, the result of the Eaton Method is more plausible than that of the Soil Mechanics Method. This research also reveals an important inference: if there is a pressure discrepancy, then it is likely that a hydrodynamic condition is present.
SPECTRAL DECOMPOSITION TECHNIQUE BASED ON STFT AND CWT FOR IDENTIFYING THE HYDROCARBON RESERVOIR
Authors: Haris Abdul , Haryono Haryono , Riyanto Agus
Published: January 2022

The spectral decomposition is one of the advanced interpretation techniques such as seismic inversion, amplitude versus offset analysis, and seismic attribute that helpful in direct interpretative approach in seismic exploration. This technique is a transformation algorithm, thus a signal can be transformed into its varying frequency contained in the seismic signal. There are a variety of spectral decomposition algorithms in the decomposing seismic signal from time domain into frequency domain. These algorithms include Short Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT). The STFT algorithm is a conventional and simple technique for computing a time-frequency spectrum, which is based on the application of Fourier transform. However, the STFT algorithm has a problem related to the frequency resolution. In its implementation, this algorithm is limited by predefi ned window length. In contrast, the CWT algorithm is believed to be able to overcome the limitation of window length. The CWT threats wavelet at certain window length, which is defi ned by the characteristics of the wavelet. In this study, the comparison between spectral decomposition technique based on STFT and CWT method was performed, particularly in its application to the synthetic and real data set. Each algorithm has its own advantages and disadvantages in decomposing the seismic signal. Further, this analysis can be used as a reference to select one of two algorithms for the specifi c application. The synthetic data set application shows that CWT algorithm produces better frequency resolution compared to STFT algorithm. In addition, the real data set application shows that time frequency section of the seismic line provides a spectral feature, which is useful to identify the hydrocarbon reservoir, which is associated with low-frequency shadow zone.
MOLECULAR DYNAMICS STUDY OF OLEIC ACID-BASED SURFACTANTS FOR ENHANCED OIL RECOVERY
Authors: Suhendar Aang , Hertadi Rukman , Alli Yani F
Published: January 2022

Surfactants have been intensively used for Enhanced Oil Recovery (EOR). Nevertheless, environmental issues cause some surfactants to become unfavored in EOR application. Biodegradable surfactants are the suitable choice to make the environment safer. However, screening surfactants that have a good performance for EOR are time-consuming and costly. Molecular Dynamics (MD) simulation is an alternative solution to reduce cost and time. In the present study, oleic acid-based surfactants that combined with the various length of polyethylene glycol were studied. The potential surfactants were screened by MD simulation to evaluate their ability to reduce the Interfacial Tension (IFT) between oil and water layers, which is the by GROMACS software with Gromos force field and SPC water model. Carboxyl-terminal of the oleic acid was substituted by a different length of polyethylene glycol. All MD simulations were prepared in octadecanewater mixture with temperature ranges of 303-363 K. Our simulations found that the increasing number of polyethylene glycol was not always followed by the decreasing of IFT value between octadecane and water layers. These results were validated with the experimental data and found the similar IFT profile. The simulation of oil emulsification showed that all surfactant samples have good performance and stability as exhibited by their emulsification rate and emulsion stability in different temperatures. The last test to get the best surfactant was the wetability test. The simulation gave the result that both PEG100-oleic and PEG400-oleic were able to change wetability of rocks from oil-wet to water-wet. Accordingly, PEG400-oleic is the best nonionic surfactant candidate due to its performance in each simulation test.
THE EFFECT OF ELECTROLYTES ON POLYMER VISCOSITY FOR EFFECTIVENESS OF POLYMER INJECTION
Authors: Alli Yani Faozani
Published: January 2022

The use of polymer for tertiary oil recovery has been known to be important as viscosity modifier to increase sweep efficiency of water flood and chemical flood. The most common polymer used for chemical flood is hydrolyzed polyacrylamide (HPAM) that owing large number of charges along the polymer chains. However, formation water as dissolution water contain high electrolytes that has a great effect on polymer viscosity, as well as responsible to generate the efficiency of polymer flooding. In this study, the effect of electrolytes from saline and cation divalent to the viscosity of polymer was investigated. Three studied polymers were dissolved in various concentration of saline and cation divalent by analyzing the compatibility, viscosity, and the filtration ratio of polymers. The results showed that the presence of electrolytes in every concentration of water did not impact the compatibility and filtration ratio of polymers. Whereas, the addition of sodium chloride as saline ionic and calcium chloride as cationic divalent were both reducing the viscosity of polymers. The lower viscosity of polymer related to the ability of polymer to expand the hydrodynamic which limited by the neutralization of internal repulsion of the electrolytes.

Published: January 2022

In the era of industry 4.0, digitalization is a very significant step to adopt in a company. Every worldly renowned industry, oil and gas included, needs to assimilate this term into its business process. Reserves and resources report depicts an oil and gas company future cash flow, wealth, performance, as well as growth. Therefore, creating and managing this report need meticulous attention. In order to comply with demand in industry 4.0 and simplify reserves and resources reporting process, reserves and resources database and web-based application need to be developed. First task to carry in establishing database is to create and input master data. Companies’ asset is classified into four common entities: asset, area, structure, and layer – as the smallest entity. Layer contains fluid type and oil and gas specific attributes. After master data is established, a web-based application to handle data transaction and reporting is developed. In order to maintain data security, access to this application is restricted into four roles: data entry user, data approval user, administrator, and management. Every role has its own privilege, for example data entry user can create, edit, and view data, while management can only view it. Other employees that need to access this application are based on management approval and restricted into view privilege under their asset location. This application has already been tested in two reserves and resources reporting window, and underwent bug-fixing and improvement process. Implementing this application in oil and gas company’s business process gives several benefits: minimizing human error, establishing a single data source, and cutting time consumption in creating reserves and resources report. This application is the solution in creating and managing the report, as well as displaying data in graphical view to help management makes corporate decision.

Published: January 2022

With a simultaneous increasing demand for oil and large decreases worldwide in newly discovered oil reserves in the past few decades, much attention has been paid to more effi cient production approaches such as enhanced-oil-recovery (EOR) methods for developing oil and gas from existing reservoirs (Li et al., 2014). Basically, there are two types of polymers; biopolymers and synthetic polymers (Cenk et al., 2017). Method used for this study is reservoir simulation by Computer Modeling Group (CMG) STARS simulator. The study concerns to investigate and analyze the polymer sensitivity on two diff erent types of polymer: synthetic polymer and biopolymer. The simulation is done on 15x15x4 grid for 3653 days (10 years). The simulation indicates that the biopolymer injection shows more stable result in compare to synthetic polymer. The biopolymer’s adsorption occurs on smaller area and takes longer time. Conversely, the adsorption of synthetic polymer goes on bigger area of the reservoir and transpire on shorter time. Considering these facts, the use of biopolymers is more eff ective in order to increase the sweep effi ciency by reducing viscous fi ngering of chemical injection in reservoir.

The Rangkasbitung Basin, is a part of Banten Depression which was formed by a normal fault, and then fi lled by marine deposits. This research carried out to understand the sedimentation process of Middle Miocene Bojongmanik deposits, the age, paleoenvironment and lithology (sediment sequence). In this research, 55 samples were taken from the study area, approximately 595 km2. Measurement of the stratigraphic section is carried out to determine the correlation both vertically and horizontally. The residue of dissolving peroxide method was carried out during the samples preparation. Then genus and species of planktonic and benthonic foraminifera were identifi ed and determined. The foraminifera analysis guide has been used to determine the age and depositional environment. The sequences of Bojongmanik Formation were deposited in Middle to Upper Miocene (N9 to N17). Based on the planktonic foraminifera distribution, the succession of each sequence can be correlated. During Middle Miocene (N9 - N12), the lowest part of Bojongmanik Formation is deposited at 100m-200m and 100m-80m depth, while in the other site, the correlated sequence is recorded that deposited at 80m-20m depth (outer to edge of inner neritic facies). In late Middle Miocene (N13 - N14), the regression process was happened. Almost the succession was deposited on land, while in deep site, a less part of sediments was formed as land facies but the most of it deposited as marine facies. In Upper Miocene (N 15 - N 17), the sedimentation continued in the transitional to edge neritic in back mangrove to mangrove environmental setting (upper to lower delta plain), and in other sites the sediment is no longer formed. Based on distribution of benthonic foraminifera there are observed the biofacies changes laterally. In bathymetric of depositional environment maps it can be depicted two higher paleoenvironmental sites (Cigudeg and Muncang highs) and two lower sites (Leuwiliang and Jasinga basins).

Heavy oil which is classifi ed as non conventional oil is the target of exploration in the world. In Indonesia, the potential for heavy oil exploration is quite large, especially in the Central Sumatra basin. This study aims to map the location of potential heavy oil based on remote sensing data and regional gravity data supported by a geographic information system. Landsat 8 OLI satellite data is processed to produce 567 (RGB) color composite images, then further processing is carried out with DEM data to produce fusion images; mapping the vegetation index, clay mineral index, iron oxide index, surface temperature. The gravity data is used for mapping subsurface geological structures. Overlay analysis is carried out on the results of remote sensing data processing and interpretation of surface and subsurface geology. Based on the analysis, it shows that heavy oil fi elds are generally found on the surface and subsurface structures which are relatively identical and located on the edge of the basement high. Based on this analysis, the locations that have the potential for heavy oil and gas traps are on the northeast edge, Dalu-dalu High, the edge of Kampar High, the west edge of Kuantan High, the southwest edge of the Beruk High, the southwest edge of the Sembilan High.

Las universidades peruanas están obligadas a articular sus políticas bajo un modelo de Gobierno Abierto (GA) según la Ley n° 27 806 de Transparencia y Acceso a la Información Pública, con el propósito de garantizar la transparencia de la gestión institucional mediante la implementación de herramientas como portales web que garanticen una participación democrática digital. El objetivo del estudio fue determinar la relación entre la gestión del Gobierno Abierto y el uso del portal de transparencia en una universidad pública peruana. Para ello, se realizó una investigación básica de enfoque cuantitativo y diseño no experimental correlacional. Se aplicó una encuesta a través de dos cuestionarios a una muestra de 48 trabajadores encargados de publicar información. Los resultados y conclusiones revelan que el nivel de gestión del gobierno abierto y el uso de portal de transparencia son aceptables, con una correlación directa (r=0.5) y con un sig. unilateral igual a 0.000 (p valor<0.01). No obstante, existe desconfianza sobre la gestión del gobierno abierto y la utilidad del portal. Es decir, la institución superior adolece de estrategias o políticas de apertura gubernamental, lo que ocasiona baja participación pública en la gestión del gobierno universitario.

Ulysse, 1982, de Agnès Varda. Breve estudio acerca de la temporalidad de un cortometraje sobre una fotografía
Authors: Rabadán Villalpando María Eugenia
Published: January 2022

RESUMEN
Este trabajo trata de analizar Ulysse, 1982, de Agnès Varda: un cortometraje sobre una fotografía tomada por la misma autora en una playa de La Mancha veintiocho años atrás a un hombre egipcio, a un niño, y a una cabra muerta.
El análisis tiene lugar en el ámbito de los estudios sobre artes visuales. Particularmente, en la tradición de teorías sobre la temporalidad en el análisis de las obras. Esta tradición, que forma la trama y urdimbre de este trabajo, refiere autores como George Kubler, George Didi-Huberman, Alexander Nagel, Christopher Wood, y Thomas Kuhn entre otros.
El tema central de Ulysse –como también lo ha declarado la autora– además de la cuestión de la memoria y el tiempo, es la relación de la memoria y la representación en la imagen. ¿Cómo la memoria puede ser representada en la imagen en movimiento sobrepuesta a la imagen fija? ¿Cómo la filmación incluye el complejo entramado de tiempos anteriores, en constante actualización, proyectados a futuro, simultáneos, paralelos, coexistentes en el cortometraje? Intento, por tanto, examinar estas diferentes temporalidades contenidas en Ulysse, y el sentido de la plasticidad que da forma al trabajo de Agnès Varda.
Análisis visual de la representación de violencia y el poder de una fotografía de moda

Published: January 2022

En este documento se presenta el análisis visual de una fotografía de moda perteneciente a la campaña de marca Duncan Quinn del 2008, mediante la descripción, análisis e interpretación  y explicación de los motivos/signos indumentarios que se presentan para formular en primer lugar, narrativas que construyen identidades contemporáneas dentro de los discursos de género y poder. Y, en segundo lugar, un acercamiento a la fotografía de moda y al estilo conocido por los medios especializado en moda como porno-chicque  se utilizó como recurso creativo desde 1970 hasta 2010 impactando considerablemente en la publicidad de moda. En este sentido, las conjeturas que se presentan en este documento son un análisis semiótico y hermenéutico que buscan acercar al espectador a la reflexión sobre cómo los signos indumentarios que se observan fotografía pueden generar discursos específicos asociados a ideologías de género e imaginarios sobre el “hombre exitoso” en las sociedades de consumo.

Bibliometrics, a useful tool within the field of research
Authors: Salinas-Ríos Karla , García López Ang´élica Janneire
Published: January 2022

The activity in scientific research has been able to be studied, measured, compared, analyzed and objectified through Scientometrics, discipline that applies to all the literature of scientific character, mathematical and statistical methods, thus achieving, that social aspects of science can be quantified. From the scientific literature, scientific publications (tangible products of the research) are derived, which are specifically studied by the bibliometrics. This last one, is a branch of the Scientometrics, that is guided under the assumption that the scientific discoveries and the research results are published in scientific journals, so its unit of analysis is the scientific article. The word bibliometrics was defined for first time by Alan Pritchard in 1969, and since then, multiple concepts of this term have been developed. However, it has reached to the consensus that this methodological tool allows to know the scientific production (in quantity, quality and impact) on various topics, journals, authors and countries, among others. Its main research lines are the methodology for bibliometrics, the scientific disciplines and the health management and policies. Likewise, it has descriptive, evaluation and supervision/monitoring functions of the research activity, on which its classification into levels (micro, meso and maso) will depend directly. Because it has components from various sciences, among them the mathematics, its methodology and theory are based on mathematical models, from which the bibliometric indicators are derived. Although there are other types of research such as systematic reviews and meta-analyzes, these, require a better management in the field of research and of the statistical measurement, as well as more resources. On the other hand, a bibliometric study owns the nobility of being within the reach of students and researchers due to its methodology, practicality, relevance, resource saving, potential to extend to most of the scientific areas, multiple applications and favoring the fact of not committing ethical misconduct related to research. Finally, although bibliometrics is often underestimated, its power and importance as a tool to manage evidence-based knowledge and to serve as a basis for other types of studies such as systematic reviews must be emphasized.
Allergic Rhinitis: keys for the clinician
Authors: Campuzano-Revilla Gabriela Paola
Published: January 2022

Allergic rhinitis (AR) and asthma are the most common inflammatory diseases of the airways. According to the review of the literature, there is a prevalence of AR of 10-40% worldwide. AR is defined as a type I allergic disease caused by immunoglobulin E mediated inflammation. The symptoms include nasal congestion, watery rhinorrhea and sneezing.

Authors: Ruiz Valenciano Juan Arturo
Published: January 2022

El presente trabajo de investigación buscó describir las medidas de creación liquidez en la banca propuestas por Deep y Schaefer (2004) y Berger y Bouwman (2009), las cuales se fundamentan en la teoría de intermediación financiera, donde se hace mención que la creación de liquidez otorgada por los bancos es de suma importancia para las economías en las que interactúan. Ambas medidas fueron aplicadas a la banca múltiple mexicana, de manera consolidada con datos mensuales en un periodo comprendido de diciembre 2000 a diciembre 2020. Los resultados reportan una creación de liquidez a la baja, es decir, hay evidencia de una destrucción de liquidez por parte del gremio bancario en México.

Published: January 2022

Environmental, Social, and Governance investing has undergone a radical shift; companies and investors have focused on the impact of the disclosure of the practices and policies related to the environment, social responsibility, and governance in their operational strategies and investment. The purpose of this paper is to demonstrate the impact that the ESG policies have on public companies' stock returns in Australia and Japan. Accounting and market-based measures are used to determine the impact ESG practices have on stock market index returns. The annual data used is of companies from Australia's S&P/ASX Index and Japan's Nikkei 225 Index, covering the period from 2005 to 2019. Fixed effect model regression was used to test the significant relationship between companies' stock returns and ESG score, accounting, and market-based measures. Portfolios were created to analyze the risk/return relationship between companies with and without ESG across countries. The findings indicate mixed results. Australia´s non-ESG portfolios outperform the S&P500 and ESG portfolios. Japan´s portfolio has positive returns but underperforms the benchmark. Low market capitalization portfolios with and without ESG outperform the higher capitalization portfolios.

Authors: García García Ana María , Vargas Piñón Mauricio , Hernández Aguilar Minerva
Published: January 2022

La situación de distanciamiento social derivada de la pandemia por el COVID-19, donde fue necesario que las personas se mantuvieran aisladas dentro de sus hogares, afectó con la reducción de ventas de los micronegocios conocidos como tienditas de la esquina. Este grupo de negocios dependían para sus ventas del tránsito de personas, por lo que bajo las condiciones de restricción de movilidad su permanencia se vio comprometida. Derivado del poco conocimiento que este tipo de negocios tenían sobre el comercio electrónico, no se encontraban en condiciones de poder migrar o complementar su actividad comercial con el apoyo de las TIC´´´´´´ s. El surgimiento de plataformas como Wabi, resultó en una alternativa viable para mantenerse vigentes en el mercado. El objetivo del presente artículo es reportar los resultados del pilotaje del instrumento a emplear en entrevistas estructuradas y así determinar las razones y beneficios percibidos por los micronegocios para ingresar al comercio electrónico, derivado de la situación provocada por la pandemia por COVID-19. Para ello, se hicieron entrevistas estructuradas a tendajones, misceláneas y tienditas de la esquina, para sondear su experiencia en Wabi. Los resultados demostraron que deben hacerse adecuaciones al instrumento en las preguntas relacionadas con las variables, beneficios impulsores y problemas, ya que en varios momentos se llegan a identificar como elementos estrechamente relacionados. Sin embargo, después del pilotaje de la prueba, se considera que el resto de las preguntas del instrumento es pertinente y permite medir las variables de manera adecuada.
