In today’s e-banking, customers compete for comparative time-saving-options. Banks compete for maximizing profits. But many factors are unpredictable. These are perceived risks factors (PR) that undermines growth trends of e-banking in economy country-wise such as Russia. Bank-deposits, bank-accounts are covered by Deposit Insurance System (DIS) in Russian-economy. However, PR-factors are not covered. It causes abuses. Addressing the dilemma, application of Akim’s model – Voluntary Insurance (VI) as a product can be instrumental attracting more individuals using e-banking. Welfare Analyses are used as guidance for ensuring efficiency-cost or competitive pricing of the VI so that it becomes appealing to both customers and Banks. When bank is an insurance-provider, under asymmetric-information, existence of adverse-selection-group is detected where estimated welfare-cost associated with inefficient pricing created by adverse-selection is small. However, advantageous-selection-group in market results opposite. The findings can be helpful in policy-design ensuring risk-free digital-banking, which can attract policy-practitioners in Russia. Using customers-opinions can facilitate empirical studies.

The article investigates the features of ensuring the hardness of surface hardening and restoration of machine parts and mechanisms using the method of modulated current surfacing. Preliminary research on methodsand results of surface hard-ening has been studied. A cycle of experiments was planned and performed using a number of variable parameters of the arc process. The results of experimental researches received at surfacing with modulation of modes of arc process with the con-trolled characteristics of the modulated influence are presented and analyzed. All studies for comparison were performed withstationary and modulated processes. A mathematical model of the dependences of the hardness of the deposited layers on the main modulation parameters has been developed. Regression analysis is used to create a mathematical model. Graphs of such dependences are constructed for an example and visualization. Microsections of surfacing with definition of features of struc-ture of metal are considered. It is established that the parameters of modulation of surfacing modes significantly affect thecharacteristics of the deposited layer and can be significantly improved. The research used common equipment -surfacing machine and current source, as well as a special modulator and flux cored wire. The microsections of the sections of the welded rollers made in comparison with the formation of certain conclusions about the structures of the surfacing metal are considered and studied. Substantiated conclusions about the increase of hardness are the consequences of structural transformations of the weld metal under the action of modulated influence. It is noted that the obtained results can serve as a basis for purposeful selection of parameters of the modulated surfacing process to obtain a coating with a better layer, as well as to predict the surfacing properties. Surfacing using a modulation cycle can be common in various industries
Law Firm Dynamics: Don't Hate the Player, Hate the Game
Authors: Kimbrough Tom
Published: June 2022

This paper concerns the business of law, a subject ignored by legal academia and sugarcoated by the organized bar. If law professors express little or no interest in this subject, their students most certainly do. Indeed, I have found that students are desperately hungry for information on the day-to-day realities of working in a law firm. Students are especially keen to learn about possible paths for career advancement within firms, across them, or across the organizations served by the firms.

Paths for career advancement do exist, but they are not easy to find or pursue. Law firms are hardly going to assist their younger lawyers in this endeavor, as the interests of senior lawyers do not align with the interests of the associates. In fact, senior lawyers are engaged in competition with each other. As a result, younger lawyers may experience significant uncertainty and frustration in determining how to promote their careers.
This paper is my attempt to shed light on the hidden law firm dynamics likely to shape the career success or failure of junior lawyers working in law firms. Such knowledge may empower associates to think strategically about their careers, as their senior colleagues already do. The ideas presented here are based on my fourteen years of teaching in a law school and my eleven years working as an associate attorney or foreign legal consultant at four law firms in three countries.

The performance of the winged pearl oyster Pteria colymbus juveniles under suspended culture conditions was evaluate, including five culture methods and two seasons: upwelling and non-upwelling. Culture methods comprised enclosures confining the oysters: BTBC, BBOand BTO; and two other unconfined-oyster: OFOB and FNS. The initial shell height of the oysters ranged between 31–35 mm in both seasons. The increase in shell size and dry mass of soft tissues showed significant differences between seasons. Greatest growth occurred with the OFOB and FNS unconfined methods. The ANOVA II analysis showed significant differences between the variables obtained in both stations and culture methods. Principal Component Analysis showed that the interactions between the variables: temperature (inverse relationship), and UI, chl-a and POM (direct relationship) explained 89 % of the variability of the growth of the oysters. Given the low survival rates, attributed to the presence of predators within the closed enclosures and the higher growth seen in the culture methods without confinement, we recommend using the FNS and OFOB methods, taking advantage of the byssus produced by P. colymbus.

Seagrass meadows have stood out for being very effective fixing atmospheric carbon, among others, due to their ability to produce plant biomass. Therefore, the values of shoot density (m2), biomass (cores) and carbon present in 12 locations with Thalassia testudinum at the Colombian Caribbean (La Guajira and San Andrés Island) were quantified. The biological samples were processed in laboratory until obtaining the values of aerial, underground and total dry weight, and the estimation of the carbon was stablishing from a ratio of 35 % of the dry biomass. Statistical tests were carried out to determine significant differences between the sites, highlighting the aerial biomass in La Guajira and the underground biomass in San Andrés. It was calculated that the total carbon in the seagrasses’ biomass from La Guajira were 197 484 Mg C and in San Andrés 1835.4 Mg C. The difference between locations were due to particular geomorphological and intrinsic factors. It is highlighted that, although the carbon retained in the biomass (aerial and underground) is comparatively lower than in sediments, it constitutes the pillar of conservation of both carbon sink as well as for the sustainability of the ecosystem.

Learning materials should optimally accommodate higher-order thinking skills (HOTS) to train students to think critically. The research aimed to describe the content of HOTS in Indonesian language textbooks for eighth grade found in the materials, examples, and exercises. Bloom's taxonomic cognitive theory by Anderson and Krathwohl was used in this study. This type of research was qualitative research with a content analysis approach. The data collection techniques were document analysis and interviews. Data analysis techniques employed model intertwined with the stages of data collection, data reduction, data presentation, withdrawal of conclusions, and return to data collection—techniques of presenting the results of data analysis using informal methods. Data sources were documents that include an Indonesian language textbook for eighth grade published by the Ministry of Education and Culture and Mahir Berbahasa Indonesia textbook published by Erlangga, and informants were Indonesian language teachers. Data validity test techniques used triangulation methods and data sources. The results showed HOTS provided in the textbook published by Kemendikbud, which was 3.8% of the material, 53% of example, and 38.9% of exercise. From the textbook published by Erlangga, HOTS provided 12.6% of the material, 44% of the example, and 33.2% of the exercise. The results reveal that the textbook published by the Ministry of Education and Culture provides more high-level thinking skills content, and Erlangga's book provides more detailed information about students' ability to think at high levels.
Polymer-Induced Biofilms for Enhanced Biocatalysis

Published: June 2022

The intrinsic resilience of biofilms to environmental conditions makes them an attractive plat-form for biocatalysis, bioremediation, agriculture or consumer health. However, one of the main challenges in these areas is that beneficial bacteria are not necessarily good at biofilm formation. Currently, this problem is solved by genetic engineering or experimental evolution, techniques that can be costly and time consuming, require expertise in molecular biology and/or microbiolo-gy and, more importantly, are not suitable for all types of microorganisms or applications. Here we show that synthetic polymers can be used as an alternative, working as simple additives to nucleate the formation of biofilms. Using MC4100, a strain of Escherichia coli that forms bio-films poorly, we demonstrate that hydrophobic polymers induce clustering and promote biofilm formation in this bacterium, with increasingly hydrophobic polymers outperforming less hydro-phobic polymers. Moreover, we compare the effect of the polymers on MC4100 against PHL644, an E. coli strain that forms biofilms well due to a single point mutation which increases expres-sion of the adhesin curli. In the presence of selected polymers MC4100 can reach levels of bio-mass production and curli expression similar or higher than PHL644, demonstrating that syn-thetic polymers promote similar changes in microbial physiology than those introduced following genetic modification. Finally, we demonstrate that these polymers can be used to improve the performance of MC4100 biofilms in the biocatalytic transformation of 5-fluoroindole into 5-fluorotryptophan. Our results show that incubation with these synthetic polymers helps MC4100 match and even outperform PHL644 in this biotransformation, demonstrating that synthetic polymers can underpin the development of beneficial applications of biofilms.

Published: June 2022

Designing highly selective molecules for a drug target protein is a challenging task in drug discovery. This task can be regarded as a multiobjective problem that simultaneously satisfies a criteria of various objectives, such as selectivity for a target protein, pharmacokinetics endpoints, and drug-like indices. Recent breakthroughs in artificial intelligence have accelerated the development of molecular structure generation methods, and various researchers have applied them to computational drug designs and successfully proposed promising drug candidates. However, designing efficient selective inhibitors with releasing activities against various homologs of a target protein remains a difficult issue. In this study, we developed a de novo structure generator based on reinforcement learning that is capable of simultaneously optimizing multiobjective problems. Our structure generator successfully proposed selective inhibitors for tyrosine-kinases while optimizing 18 objectives consisting of the inhibitory activities against nine tyrosine kinases, three pharmacokinetics endpoints, and six other important properties. These results show that our structure generator and optimization strategy for selective inhibitors will contribute to the further development of practical structure generators for drug designs.
New insights into the kinetics of metal|electrolyte interphase growth in solid-state-batteries via an operando XPS analysis - part I: experiments
Authors: Quérel Edouard , Williams Nicholas J. , Seymour Ieuan D. , Skinner Stephen J. , Aguadero Ainara
Published: June 2022

To harness all the benefits of solid-state battery (SSB) architectures in terms of energy density, their negative electrode should be an alkali metal. However, the high chemical potential of alkali metals make them prone to reduce most solid electrolytes (SE), resulting in a decomposition layer called an interphase at the metal|SE interface. Quantitative information about the interphase chemical composition and rate of formation are challenging to obtain because the reaction occurs at a buried interface. In this study, a thin layer of Na metal (Na0) is plated on the surface of a SE of the NaSICON family (Na3.4Zr2Si2.4P0.6O12 or NZSP) inside a commercial XPS system whilst continuously analysing the composition of the interphase operando. We identify the existence of an interphase at the Na0|NZSP interface, and more importantly, we demonstrate for the first time that this protocol can be used to study the kinetics of interphase formation. A second important outcome of this article is that the surface chemistry of NZSP samples can be tuned to improve their stability against Na0. It is demonstrated by XPS and time-resolved electrochemical impedance spectroscopy (EIS) that a native Na3PO4 layer present on the surface of as-sintered NZSP samples protects their surface against decomposition.

Published: June 2022

A series of Ru(III)-PyNHC complexes, identified as [RuIII(PyNHCR)(Cl)3(H2O)] (1a-c), have been prepared following a base-free route. The structurally simple, air and moisture stable complexes represent rare examples of Ru(III)-NHC complexes. Further, these benchtop stable Ru(III)-PyNHC complexes were shown to be excellent metal precursors for the synthesis of new [RuII(PyNHCR)(Cl)2(PPh3)2] (2a-c) and [RuII(PyNHCR)(CNCMe)I]PF6 (3a-c) pincer complexes. All the complexes have been characterised using spectroscopic methods, and structures of 1a, 1b, 2c and 3a have been determined using the single-crystal X-ray diffraction technique.
From eating to obesity: issues of diagnosis and neuroendocrine regulation. A review
Authors: Maksim Oksana V. , Salukhov Vladimir V.
Published: June 2022

The problem of eating disorders, as well as the problem of obesity, is multidisciplinary and does not lose its relevance. The violation of the food pattern is caused by the influence of many factors, such as genetic, humoral, psychological, psychosocial, etc. The implementation of eating behavior is carried out through neurohumoral interaction at various levels of regulation, including the structures of the central, autonomic nervous system and the gastrointestinal tract, the functional characteristics of which are currently time continue to be actively studied. The functional characteristics of the intestinal microbiota play a significant role in the hedonistic and humoral regulation of eating behavior. Alimentary obesity is considered as a psychosomatic disease, which is formed as a result of eating disorders by the type of overeating.
Association of anthropometric parameters with the risk of developing type 2 diabetes in overweight or obese individuals: cohort prospective study
Authors: Valeeva Farida V. , Khasanova Kamilya B. , Yilmaz Tatyana S. , Mansurova Rezida G.
Published: June 2022

Background. Type 2 diabetes mellitus (T2DM) is a non-infectious pandemic of the 21st century. The severity and complexity of this disease is associated with the development and progression of chronic complications that begin at the stage of early carbohydrate and fat metabolism disorders.
Aim. To identify the leading anthropometric predictors of the development of type 2 diabetes in overweight or obese patients with early carbohydrate metabolism disorders.
Materials and methods. The cohort prospective study involved 112 overweight or obese adults (all citizens of Russia, Republic of Tatarstan) aged 22 to 79. The study was carried out from 2016 to 2018 in the City polyclinic №18. R 4.1.0 environment was used for statistical analysis. Univariable and multivariable logistic regression modeling were performed to evaluate association between outcomes and possible predictors, odds ratios with 95% confidence intervals were estimated. Area under the ROC-curve and Nagelkerke pseudo R-squared was used to compare prognostic performance of predictors.
Results. During 3 years of follow-up of 112 patients with early carbohydrate metabolism disorders (prediabetes; n=64), without prediabetes (n=48) without medical intervention, new cases of type 2 diabetes in people with prediabetes and obesity amounted to 29% (n=18) compared with 6% (n=3) for patients with normal glucose levels. The ratio of waist circumference to height (WHtR) and the ratio of waist to hip circumference (WHR) had the greatest discriminative ability according to univariate and multifactorial analyses.
Discussion. Our study is consistent with previous work indicating a negative impact of visceral adipose tissue on the risk of developing T2DM. WHR and WHtR most accurately reveal the visceral type of obesity. WHR and WHtR are statistically significant parameters for assessing the risk of developing T2DM according to our study.
Conclusion. WHR and WHtR can be used as predictors of type 2 diabetes in overweight or obese individuals.

The PPARG gene has the great value in predicting of carbohydrate metabolism disorders development and the patients response to different therapy options. The article presents the information about the association between the single nucleotide polymorphism rs1801282 PPARG and the risk of different carbohydrate metabolism disorders development based on a review of the domestic and foreign researches. Despite that literature data regarding the association of this polymorphism with the development of metabolic disorders differ, most researchers agree that the G-allele of rs1801282 PPARG has the protective effect in relation to the risk of carbohydrate metabolism disorders development. The particular emphasis is placed on the association of rs1801282 PPARG with the results of carbohydrate metabolism disorders management, taking into account the lifestyle changes as well as the intake of oral hypoglycemic drugs used in the treatment of prediabetes and type 2 diabetes. Thus, a number of studies have shown that the G-allele carriers of rs1801282 PPARG had a better response to pioglitazone treatment in the form of lowering of fasting glucose and A1C levels and lipid profile normalization. The association of the polymorphism with the results of therapy with metformin remains an open question that requires further study.
The role Time in range depending on the method of assessing glycemic control in diabetes: A review
Authors: Suplotova Lyudmila A. , Sudnitsyna Anna S. , Dushina Tatyana S.
Published: June 2022

Despite modern advances in diabetology, diabetes is a progressive non-communicable disease with the possible development of vascular complications, which is a global health problem. Therefore, maintaining optimal glycemic control is important for managing diabetes and preventing the development of acute and chronic complications of the disease. One of the parameters for assessing glycemic control is the indicator of time in the target range (Time in range TIR), calculated on the basis of data from continuous glucose monitoring (CGM), which is quite simple and convenient to calculate and use, and also has a proven connection with the development of micro- and macrovascular complications of diabetes. However, the main obstacle to the widespread use of TIR is the limited use of CGM systems. Therefore, of particular interest is the study of the derived indicator of the time in range of glycemia (derived TIR dTIR), obtained on the basis of self-monitoring of blood glucose. In this review, the issues of the relationship of TIR, dTIR with HbA1c levels, the development of micro- and macrovascular complications of diabetes type 1 and 2 are discussed, and the comparability of TIR and dTIR is analyzed.
The Lightning Network: Turning Bitcoin into Money
Authors: Divakaruni Anantha , Zimmerman Peter N.
Published: June 2022

The Lightning Network (LN) is a means of netting Bitcoin payments outside the blockchain. We find a significant association between LN adoption and reduced blockchain congestion, suggesting that the LN has helped improve the efficiency of Bitcoin as a means of payment. This improvement cannot be explained by other factors, such as changes in demand or the adoption of SegWit. We find mixed evidence on whether increased centralization in the Lightning Network has improved its efficiency. Our findings have implications for the future of cryptocurrencies as a means of payment and their environmental footprint.

Objetivo.

Estimar el impacto de la pandemia de la COVID-19 durante el año 2020, a través del exceso de mortalidad por todas las causas y los años potenciales de vida laboral perdidos en la población en edad de trabajar, de una selección de países latinoamericanos y el Caribe.

Métodos.

Estudio basado en datos de defunciones por todas las causas entre 15 y 69 años, procedentes principalmente de los Institutos Nacionales de Estadísticas. Se estimaron defunciones esperadas a partir de las registradas entre 2015 y 2019. El exceso de mortalidad fue estimado a través del indicador P, la razón de mortalidad estandarizada (RME) y los años potenciales de vida laboral perdidos (AVLP) hasta los 70 años.

Resultados.

El exceso de defunciones en Brasil, Bolivia, Chile, Colombia, Costa Rica, Cuba, México, Perú y República Dominicana sumó 426 978 (279 591 en hombres y 147 438 en mujeres), lo que representó una pérdida de 5 710 048 (3 738 775 en hombres y 1 971 273 en mujeres) de APVLP. La mortalidad observada fue significativamente superior a la esperada en todos los países, menos República Dominicana.

Conclusiones.

El impacto de la COVID-19 en la población en edad de trabajar tendrá un impacto profundo en la situación socioeconómica. El recuento oportuno del exceso de muertes resulta útil y puede ser usado como un sistema de alerta temprana para monitorizar la magnitud de los brotes de COVID-19.

Brucelosis como causa de fiebre persistente en un trabajador de la salud de Cali, Colombia. Reporte de caso.
Authors: Araque-Villaquiran Fernando , Peña Guevara Antonio Alejandro , Carvajal-Mazuera Antonio Jose , Loaiza Giraldo Juliana
Published: June 2022

Introducción. La brucelosis es la principal zoonosis a nivel mundial. Es transmitida al ser humano principalmente por el consumo de productos no pasteurizados, así como por exposición ocupacional. Las manifestaciones son inespecíficas lo que conlleva a un reto diagnóstico para el clínico, siendo una de las causas que pueden   explicar la fiebre de origen desconocido y la cual no se tiene como etiología relevante dado su poca incidencia en nuestro medio, dejándose como una patología probable una vez se tengan descartadas las enfermedades más frecuentes y prevalentes.
Resumen del Caso. Resumen del caso: Presentamos a un hombre joven trabajador del área de la salud con antecedente de queratocono y urolitiasis quien ingresó al servicio de urgencias por cuadro febril agudo asociado a cefalea, mialgias y artralgias con sospecha inicial de infección por dengue. Sin embargo, dada la persistencia de la fiebre por más de 96 horas tras realizarse múltiples estudios negativos y múltiples consultas al servicio de urgencias requiriendo vigilancia de forma estricta, y bajo la sospecha epidemiológica de posible cuadro de zoonosis, se consideró realizar pruebas de detección para brucelosis mediante aglutinación por antígenos febriles siendo positivo para B. abortus en títulos altos de 1:160. Se corroboraron los hallazgos mediante prueba de aglutinación por rosa de Bengala y finalmente con inmunoensayo enzimático (ELISA) con resultado positivo para IgM e IgG. Se dio tratamiento con rifampicina y doxiciclina por 6 semanas con mejoría completa sin recurrencia.
Discusión. La brucelosis puede presentarse como un cuadro febril inespecífico que si bien es muy poco frecuente en nuestro medio debe tenerse como probabilidad etiológica dado el área rural y las pocas medidas de vigilancia epidemiológica y de salubridad en el adecuado proceso de pasteurización aún en proceso de Industrialización. En este reporte mostramos que la sospecha clínica y el uso de ayudas diagnósticas de detección indirectas permitieron hacer el diagnóstico sin que estas sean las de mejor rendimiento dada su baja especificidad y posibilidad de estar presentes en múltiples procesos infecciosos, pero en el caso de este paciente fue la clave para lograr el origen de la fiebre de origen desconocido.  Si bien la mortalidad es baja, la terapia antibiótica combinada reduce la recurrencia y las complicaciones asociadas.

Bacias hidrográficas montanhosas são mais propensas aos perigos naturais, devido à ocorrência de eventos hidrológicos de alta intensidade e às características geomorfológicas destes locais, como o relevo declivoso e a presença de leques aluviais. O presente estudo teve como objetivo avaliar a inundação em bacias hidrográficas montanhosas no sul do Brasil, por meio de monitoramento e modelagem com HEC-HMS e HEC-RAS 2D, visando o mapeamento de perigo de inundação. Realizou-se um levantamento dos registros históricos de inundação, ocorridos em 2007 nas regiões de leque aluvial dos rios Molha Coco e Malacara. O HEC-HMS foi calibrado e validado com dados monitorados de vazão. Os hidrogramas com as vazões máximas simuladas pelo HEC-HMS foram propagados no modelo HEC-RAS 2D. Com essas vazões foram gerados mapas de profundidades, velocidades e índice de perigo de inundação para os períodos de retorno de 5, 100 e 200 anos. Os mapas de perigo mostraram que, o maior valor do índice de perigo de inundação foi encontrado dentro da calha dos rios e nos locais de avulsão. Nesses locais, existem pousadas, restaurantes e residências, que podem sofrer danos estruturais e expor as pessoas ao perigo de um evento de inundação de magnitude elevada.Palavras-chave: Rio Montanhoso.

The present study aimed to assess the flood hazard degree in mountain basins in southern Brazil, through monitoring and modeling with HEC-HMS and HEC-RAS 2D. A survey of the historical flood records, which took place in 2007 in the alluvial fan regions of the Molha Coco and Malacara rivers, was carried out. The HEC-HMS was calibrated and validated with monitored flow data. The hydrographs with the maximum flow rates simulated by the HEC-HMS were propagated in the HEC-RAS 2D model. With these flows, maps of depth, velocity and flood hazard index were generated for the return periods of 5, 100 and 200 years. Potential hazard maps show that the highest value of the flood hazard index was found within river channels and at avulsion sites. In these places, there are inns, restaurants and residences, which can generate damage and expose people to the flood hazard with high magnitude.Keywords: Mountain river. Hazard mapping. HEC-RAS 2D.

Published: June 2022

Surface runoff is an extremely important hydrologic flowpath since it transports soil and pollutants. For this reason, low cost methods are needed to detect such process in the field. In the present paper, we present a simple surface runoff detector made of polypropylene. Its low cost along with its high repeatibility allow for the use of a high number of detectors in the field to elucidate spatial variability as well as to trace overland flow route. Simple demonstrations of the method are provided.  With this simple detector, more knowledge can be obtained on this important hydrologic pathway which is related to soil erosion and transport of a number of potential harmful substances to water bodies.

Aim/Purpose: The low proportion of women currently working in the field of business information systems presents an opportunity to attract more women to this field. For example, in Germany, the proportion of women studying business information systems is currently 21%, compared to 48% in business administration (Statistisches Bundesamt, 2020). Which characteristics make the professional field of business information systems appear attractive to women and men – and which characteristics do not?

Background: Studies on careers in business information systems are important to mitigate the long-lasting shortage of IT specialists, yet research is limited in this area.

Methodology: To capture empirical data, graduates of the Business Information Systems program at the University of Applied Sciences in Hannover were surveyed.

Contribution: The results show that women and men perceive the work climate and working conditions very differently and are also satisfied to a different extent. Characteristics of the work climate place significantly more restrictions on satisfaction for women than for men. Women primarily criticize characteristics that can be described as involving “a lack of fairness”.

Findings: The differences in perceived work climate may negatively impact the proportion of women in business information systems. A number of measures have already been established to support women in coping better with the prevailing climate. However, some measures bear the risk that women are thus accused of assimilating to the prevailing climate. This can seem pre-sumptuous since the dominant male culture is taken for granted and “set”. Measures for team-building and personnel development appear to be more suitable if these address the actual values and norms of teamwork, question them where necessary, and change them for everyone.

Recommendations for Practitioners: Women’s career goals are clearly different from men’s goals, and women do not achieve goals with high priority very well. Work climate is perceived more critically by women than by men: less fair, less supportive. Advantages of diversity and plurality are put at risk if women should put aside their different “other” perceptions of cooperation and negotiation in order to act according to the rules of the male-dominated system.

Impact on Society: Studies on careers in business information systems are important to mitigate the longer-lasting shortage of IT specialists. The low proportion of women currently working in IT presents an opportunity to attract more women to business information systems.
Understanding the Value of Enterprise Resource Planning (ERP) Systems
Authors: Talasi Teboho , F Seymour Lisa
Published: June 2022

Aim/Purpose: The purpose of this research is to explain how ERP systems provide value to companies in Lesotho, a developing country.

Background: The percentage of organizations with Enterprise Resource Planning systems (ERPs) has been increasing in both developed and developing nations. Despite the popularity of ERPs, the literature has shown that ERP failure is a major challenge facing organizations. Companies invest a considerable amount of money into these systems, expecting a return on in-vestment. Yet, findings on the benefits that organizations accrue from the implementation of ERPs are mixed. There are concerns that in developing countries the return is low.

Methodology: An online survey strategy was used for collecting data from companies. Using the simple random method, 169 companies using ERP systems were selected.

Contribution: The core contribution is in supporting proposed relationships that had not been tested prior. The empirical results of this study describe the Lesotho ERP context. The results also emphasize the importance of the use of ERP in determining the value of ERPs.

Findings: This study has confirmed that ERP usage and business processes improvements are the main factors affecting ERP value, and ERP usage is the strongest determiner of ERP value. The finding also emphasizes the importance of organizational culture and training.

Recommendations for Practitioners: Companies are encouraged to focus on training users and build a supportive organizational culture.

Recommendations for Researchers: Context plays a vital role in determining ERP value and hence should be taken into account when explaining ERP value.

Impact on Society: The paper highlights the impact of organizational culture on ERP usage and business process improvement and hence ERP value.

Future Research: While this study focused on training quality, further studies could focus on the impact of training quantity and ongoing training.

Bu çalışmada batarya sağlık durumunun belirlenmesi için makine öğrenmesi yöntemi kullanılmıştır. Bu amaçla bataryanın deşarj olması esnasında elde edilen akım, kapasite azalması, gerilim gibi değerler kullanılmıştır. Literatürdeki diğer yöntemlerden farklı olarak, deşarj gerilim grafiğindeki diz-dirsek noktaları belirlenerek gerilimdeki değişimler daha ayrıntılı olarak dikkate alınmıştır. Belirlenen giriş verileri kullanılarak batarya sağlık durumunun belirlenebilmesi için k-En Yakın Komşu yöntemi ve Rastgele Orman Regresyon yöntemi olmak üzere iki farklı makine öğrenmesi algoritması oluşturulmuştur. Gerçekleştirilen sağlık durumu belirleme yazılımı için PYHTON dili kullanılmıştır. Batarya sağlık durumunun belirlenmesi için kullanılan yöntemlerin başarısı iki farklı senaryo ile değerlendirilmiştir. İlk senaryo tüm batarya verilerinin karışık olarak değerlendirilip, tüm bataryalara ait verilerden oluşan eğitim ve test verilerinin oluşturulması ile gerçekleştirilmiştir. Diğer senaryo ise elde bulunan 12 bataryadan 11’ini eğitim verisini kalan 1 bataryanın ise test verisini oluşturduğu durumdur. Burada 12 bataryanın her biri ayrı ayrı test verisi olarak değerlendirilmiştir.
The Role of Green Supply Chain Management in Predicting Indonesian Firmsâ€™ Performance: Competitive Advantage and Board Size Influence
Authors: Novitasari Maya , Alshebami Ali Saleh , Sudrajat M. Agus
Published: June 2022

This study examines the effect of green supply chain management (GSCM) on firm performance, with competitive advantage as mediation and board size as moderation. Purposive sampling method was used to examine 516 PROPER companies from 2010 to 2018. Data were obtained from the Indonesia Stock Exchange. Results show that GSCM has a positive effect on competitive advantage but does not affect firm performance, whereas competitive advantage has a positive effect on firm performance. Moreover, competitive advantage can mediate the relationship between GSCM and firm performance. Board size cannot moderate the relationship between GSCM and competitive advantage, but it can moderate the relationship between competitive advantage and firm performance and the relationship between GSCM and firm performance. The results of this study can be used to improve firm performance of companies concerned with environmental impact. The research findings contribute to the idea that board size has a role in strengthening the implementation of GSCM to create competitive advantages that can increase firm performance.
Sustainability Reporting and Tax Aggressiveness: Evidence from a Public Company in Indonesia
Authors: Supriyati Supriyati , Anggraini Dwi Dita
Published: June 2022

This study aims to describe tax avoidance or tax aggressiveness committed by a public company in Indonesia. To maintain company sustainability, taxation strategy must always be supported by a non-financial system. In Indonesia, sustainability report disclosure is voluntary, but the Indonesian government handles the issue by requiring the inclusion of social and environmental activities in the report as taxable operational costs. The research sample of this study comprises public companies listed on the Indonesia Stock Exchange, which have submitted sustainability reports separately. A total of 68 companies were involved, from which 132 datasets were obtained for further analysis via regression test. This research introduces a new way to measure tax aggressiveness (fiscal effective tax rate) to supplement the results generated by the existing measure (GAAP effective tax rate). The development of research shows that sustainability reporting has a significant effect on tax aggressiveness committed by public companies in Indonesia.
R&D Intensity, Industrial Sensitivity, and Carbon Emissions Disclosure in Indonesia

Published: June 2022

This study examines the effect of R&D intensity and the type of industry on carbon emission disclosure (CED). The measurement of CED employs an index developed by Choi et al. (2013) based on the carbon disclosure project (CDP). The final data from this study comprise 264 company observations during the period of 2015â€“2018, sourced from a database of companies listed on the Indonesia Stock Exchange. The data were tested using ordinary least squares multiple regression. Results revealed that companies with lower R&D funding tend to disclose higher carbon emissions than those with higher R&D funding. Furthermore, companies whose operations are sensitive to carbon pollution are likely to disclose higher carbon emissions and vice versa. The findings indicate that there are more sensitive companies trying to fulfill their legitimacy to the public (stakeholders) compared to insensitive companies.
Los agroecosistemas como refugios de la biodiversidad:

Published: June 2022

Tradicionalmente, se considera que la mayor diversidad de especies ocurre en sitios conservado. Sin embargo, los ambientes modificados como los agroecosistemas pueden contener una parte importante de la diversidad original. En este trabajo, comparamos la herpetofauna de cuatro agroecosistemas en dos localidades del estado de Guanajuato. Janicho y Urireo, con un sistema de producción de temporal, y El Copal y San Nicolás de los Agustinos, con sistema de riego. Así mismo, comparamos la herpetofauna de estos sitios (no conservados) con la de sitios semiconservados y conservados del estado de Guanajuato. Encontramos que la localidad de El Copal, presento el mayor número de especies, lo que sugiere que, al ser un sistema de producción de riego, aporta a los anfibios y reptiles que se encuentran en él, refugio y alimento constante, a diferencia de las localidades de Urireo y Janicho, con sistemas de producción temporal, y que dependen de las lluvias para retener una mayor cantidad de especies. En el caso de San Nicolás de los Agustinos, consideramos que la cercanía con la selva baja permitió un flujo de especies en ambas direcciones, por ello, su menor cantidad de especies. Al hacer la comparación de los sitios (no conservados) de estudio con los semiconservados y conservados, encontramos que en conjunto albergan una herpetofauna equiparable con estos últimos. Sugerimos que los agroecosistemas, pueden funcionar a modo de zonas de refugio y alimentación temporal para las especies de anfibios y reptiles tolerantes a la perturbación, o que transitan de zonas perturbadas a aquellas semiconservadas y conservadas. Por lo tanto, sugerimos que, en estudios futuros, se analice con profundidad la estructura ecológica de estos sitios y determinar a partir de ello, hasta qué punto los agroecosistemas pueden mantener la diversidad de anfibios y reptiles.
