In field-effect transistor (FET) biosensors, charge screening in electrolyte solutions limits sensitivity, thereby restricting the applicability of FET sensors. This is particularly pronounced in graphene FET (GFET) biosensors, where the bare graphene surface possesses a strongly negative charge, which impedes the high sensitivity of GFETs owing to nonlinear electrolytic screening at the interfaces between graphene and liquid. In this study, we counteracted the negative surface charge of graphene by decorating positively charged compounds and demonstrated the sensing of C-reactive protein (CRP) with surface-charge-modulated GFETs (SCM-GFETs). We integrated multiple SCM-GFETs with anti-CRP antibodies and non-functionalized GFETs into a chip, and measured differentials to eliminate background changes to improve measurement reliability. The FET response corresponded to the fluorescence images, which visualized the specific adsorption of CRP. The estimated dissociation constant was consistent with previously reported values; this supports the conclusion that the results are attributed to specific adsorption. Conversely, the signal in GFETs without decoration was obscured by noise because of nonlinear electrolytic screening, further emphasizing the significance of surface-charge modulation. The limit of detection (LOD) of the system was determined to be 2.9 nM. This value has the potential to be improved through further optimization of the surface charges to align with specific applications. Our devices effectively circumvent nonlinear electrolytic screening, opening the door for further advancements in GFET biosensor technology.

Authors: Deota Pradeep , Singh Deepak , Bhatt Gaurang
Published: March 2023

The design and development of a simple and economical route for the construction of levuglandin skeleton from readily available isopropenyl acetate and methyl oleate has been reported. The key step involves a regio-controlled elimination of the hydroxy group resulting in the formation of a cyclobutene derivative. Oxidative cleavage of the cyclobutene derivative gives levuglandin framework in three steps. The intriguing chemistry of elimination resulting in the inseparable mixture of regioisomeric cyclobutenes has been discussed.
Evolutionary-docking targeting bacterial FtsZ
Authors: coll julio
Published: March 2023

To accurately predict binding of inhibitors to the FtsZ cell division protein of the antibiotic-resistance Staphilococcus aureus pathogen, evolutionary library docking, ligand-efficiency predictions and rank consensus docking strategies have been sequentially applied. Starting from the crystallographic FtsZ bound model of the PC190723 reference ligand, fragments were derived to generate children molecules fitting low docking-scores with low molecular sizes and hydrophobicities using the DataWarrior Build Evolutionary Library. PC190723 fragment children molecules combined with toxicity filters, and consensus ranks with ligand efficiencies and AutoDockVina docking, identified new benzamide and non-benzamide chemotypes with nanomolar docking-scores and improved specificities to continue with anti-FtsZ ligand investigations
Newton's Method to Determine Fourier Coefficients and Wave Properties for Deep Water Waves
Authors: Shin JangRyong
Published: March 2023

Since Chappelear developed a Fourier approximation method, considerable research efforts have been made. On the other hand, Fourier approximations are unsuitable for deep water waves. The purpose of this study is to provide a Fourier approximation suitable even for deep water waves and a numerical method to determine the Fourier coefficients and the wave properties. In addition, the convergence of the solution was tested in terms of its order. This paper presents a velocity potential satisfying the Laplace equation and the bottom boundary condition (BBC) with a truncated Fourier series. Two wave profiles were derived by applying the potential to the kinematic free surface boundary condition (KFSBC) and the dynamic free surface boundary condition (DFSBC). A set of nonlinear equations was represented to determine the Fourier coefficients, which were derived so that the two profiles are identical at specified phases. The set of equations was solved using Newton’s method. This study proved that there is a limit to the series order, i.e., the maximum series order is N=12, and that there is a height limitation of this method which is slightly lower than the Michell theory. The reason why the other Fourier approximations are not suitable for deep water waves is discussed.

Published: March 2023

The aim of this study is to analyze the effects of Organizational Learning (OL) and Entrepreneurial Orientation (EO) on the profitability of MSMEs. To this end, field research was conducted on a sample of 1,620 companies located in Argentina (630), Mexico (550), and Ecuador (440). The data collection was carried out between May and September 2020, through a structured questionnaire addressed to the highest level of the company. The results were analyzed and validated using the partial least square (PLS) structural equation modeling (SEM) statistical technique. This work contributes to the development of the literature on dynamic capabilities, social capital theory, and stakeholder theory. Our results reveal that Entrepreneurial Orientation is a determinant variable for generating better Environmental Corporate Social Responsibility (ESCR) practices and is key to increasing the financial profitability of MSMEs. Furthermore, it is found that ESCR is a variable that partially mediates between EO and the Performance of MSMEs.
Managerial concentration, ownership concentration, and firm value: Evidence from Spanish SMEs
Authors: Rodríguez-Valencia Leslie , Lamothe Fernández Prosper
Published: March 2023

Various corporate governance theories indicate that governance in small and medium-sized enterprises (SMEs) differs to that of larger corporations due to the ownership-management function within the organizational structure. This article provides empirical evidence of enhanced firm value in a sample of listed SMEs resulting from certain corporate governance mechanisms related to managerial and ownership concentration. The empirical analysis conducted in this paper is based on a panel data set consisting of 108 small and medium-sized public firms on the Spanish alternative stock exchange over a time frame of five years (2015-2019). The results suggest that CEO duality, the controlling shareholders, and the second largest shareholders all improve firm value. Conversely, the ratio of independent directors has a negative impact on firm value. These findings are robust to alternative model specifications such as dynamic panel estimators (Generalized Method of Moments -GMM-) and instrumental variable methods. Overall, we show that the governance configuration of listed SMEs can mitigate several of the central issues, such as agency problems, that large corporations face.

Published: March 2023

El crecimiento de las investigaciones sobre el comportamiento digital de los regímenes autoritarios muestra dispersión en los casos de estudios y los enfoques que se aplican para desarrollar los análisis de estos. En este artículo de revisión, hacemos un repaso de la literatura e identificamos los temas y los hechos que han motivado la proliferación de estos trabajos académicos. Especificamos nuestra revisión en las características que son notables en Twitter, por ser el medio de mayor presencia de los políticos en este tipo de régimen. Aunque la investigación actual ha avanzado mucho en cuanto al análisis de las condicionantes, las actividades y el impacto de los medios sociales en los regímenes autoritarios, aún creemos que son indelebles los estudios enfocados en el líder autoritario y en determinados contextos, como es el caso del latinoamericano. Por tanto, a raíz de esta pesquisa sostenemos la necesidad de continuar el desarrollo teórico y el progreso empírico. Una conclusión de este estudio es que el dominio de las visiones de China y Rusia puede ser entendida y aplicada a otros contextos autoritarios.

Catfish is one of the fisheries commodities that has good prospects for development. This is supported by the characteristics of catfish, which have high nutritional content, fast growth, are easy to breed, and can be maintained in almost all aquaculture containers. This study examines the flow of catfish marketing and analyses the differences in catfish prices in the Marusu Village, Palantikan Village, Maros Baru District, and Maros Regency. The research method was interviews assisted with a questionnaire instrument. The analysis used in this study is descriptive qualitative analysis for marketing channels and farmer's share analysis to measure the efficiency of acceptance of marketing channels for seed and catfish cultivators. The marketing channel for catfish seeds in the Marusu environment consists of 2 channels. Channel 1 starts from cultivators, collectors within the Marusu environment, and outside collectors and ends with cultivators outside the Maros area (consumers), channel 2 starts from cultivators, collectors and cultivators outside the Maros Regency area (consumers). The catfish marketing channel also consists of 2 channels. Channel 1, namely, starts with cultivators, retailers and consumers. Channel 2 is the cultivator directly to the consumer. For catfish fingerlings, farmers in marketing channels 1 and 2 are 75%, respectively. In contrast, the farmer's share in marketing channels 1 and 2 for catfish is 66.67% and 100%.

Mangrove forest is one of the ecosystems in the coastal area that plays an important role as a habitat for iktiofauna, one of which is the gelodok fish community. The purpose of this study was to compare the community structure of mudskippers at Bahak Indah Coast, Tongas, Probolinggo with or without mangrove vegetation. The study was conducted in January–February 2022. The determination of the observation station was carried out purposively, which was determined based on the presence or absence of mangrove vegetation. Observation of the mudskipper community used a systematic sampling method with the help of transects and plots. The analyzed mudskipper community structure data included diversity index, uniformity index and dominance index. The results found 4 species from 2 genera of mudskipper namely Boleophthalmus pectinirostris, Boleophthalmus boddarti, Periophthalmus chrysospilos and Periophthalmodon schlosseri. Mudskipper diversity index at both stations was in the medium category, and was higher at the stations with mangrove vegetation. The uniformity index was included in the high category, and was higher at the stations with mangrove vegetation, and the dominance index was in the low category, and lower at the stations with mangrove vegetation. The results of this study indicate that the coastal waters area with mangrove vegetation contributes to the high diversity and uniformity of the mudskipper community compared to areas without mangrove vegetation.

El caso a favor de las tecnologías digitales en la educación jurídica
Authors: Nakano Cassia , Forma Klafke Guilherme , Feferbaum Marina
Published: March 2023

The purpose of this essay is to contribute to the debate on the adoption of new technologies in legal education. It discusses Professor Daniel Bonilla Maldonado’s criticism against the legal literature’s main responses in his essay Legal Education and Technological Innovation: A Critical Essay. This paper offers two claims to substantiate the adoption of information and communication technologies (ICT) in legal education from a Brazilian perspective. The strong claim is that digital technologies are essential to teaching present-day law students. The weak claim is that digital technologies are useful and desirable in certain circumstances. Both claims try to respond to four weaknesses pointed out by Bonilla Maldonado, especially the naturalistic fallacy of the arguments supporting the incor- poration of technologies in legal education, and the lack of empirical evidence in favor of their effectiveness.

Published: March 2023

Climate change is a critical issue that strongly affects the mental state of many people and often manifests itself as so-called eco-anxiety. Eco-anxiety is mainly evoked by media reporting, as they are the main source of information about climate change. In this study, the aim was to investigate whether there is a difference in the impact of three different media types (video, radio, and newspaper) on an individual’s eco-anxiety level. By conducting a diary study in which participants received climate change-related media input at fixed intervals, the following key findings can be reported: There is a difference between eco-anxiety before and after the media intervention. The video intervention is shown to affect its participants' eco-anxiety. The other media interventions showed no effect. A correlation with neuroticism could be identified, as there is a significant influence on the pre-media intervention level of eco-anxiety and on the overall change in eco-anxiety.

Стратегический план «построения коммунизма» в СССР: амбиции и идеология хрущевской эпохи
Authors: Водичев Е.Г. , Аблажей Н.Н.
Published: March 2023

Статья посвящена анализу стратегий развития экономики в контексте декларированного властью плана по построению коммунизма в СССР. Поставленные в Программе КПСС, принятой в октябре 1961 г., и конкретизированные в «Генеральной перспективе развития народного хозяйства до 1980 г.», эти цели были призваны обеспечить глобальное экономическое лидерство СССР. Авторы исследуют конфликт в стратегическом планировании: здесь проблема заключалась не столько в неверной экстраполяции на перспективу текущих экономических трендов, сколько в фундаментальном противоречии между идеологией и экономикой. Делается вывод о доктринальной преемственности хрущевского и сталинского взглядов на горизонты развития, в том числе в плане построения коммунизма в СССР. Обновленная Программа партии с методологических позиций строилась на представлениях о доминировании индустриального вектора развития, при этом не учитывались в должной мере проявившиеся уже в 1950-е гг. тенденции постиндустриализма. Приверженность руководства страны политико-идеологическим стереотипам и ставка на глобальное лидерство блокировали развитие экономики, препятствуя поиску альтернативных путей повышения ее эффективности.

В нормативній та науково-методичній літературі питання обґрунтування потрібної номенклатури видів технічного стану складних технічних систем фактично не розглянуті, а питання обґрунтування критеріїв видів технічного стану заданої номенклатури не опрацьовані в достатній мірі. Розроблений методичний підхід містить положення щодо формування номенклатури видів технічного стану складних технічних систем та положення щодо встановлення їх критеріїв. Методичні положення щодо формування номенклатури видів технічного стану складних технічних систем включають схему формування номенклатури видів технічного стану та робочі таблиці щодо їх вибору при використанні за призначенням, при зберіганні та (або) транспортуванні. Наведений приклад таблиці щодо вибору номенклатури видів технічного стану виробів при їх використанні за призначенням, стосовно яких встановлюють вимоги щодо довговічності. Завдання встановлення критеріїв видів технічного стану виробу сформульоване як завдання розпізнавання образів. Це завдання співпадає з завданням розпізнавання (контролю) технічного стану об’єкта, що дозволяє використовувати методи теорії розпізнавання образів при розробці моделей розпізнавання технічного стану і формуванні критеріїв відмов та граничних станів. При цьому на етапі розробки складних технічних систем вирішуються питання опису всіх класів (видів технічного стану) заданого алфавіту з використанням логічних алгоритмів класифікації або алгоритмів розрахунку оцінок. Далі, в процесі випробувань складних технічних систем, сформовані при “навчанні” описи класів можуть уточнюватися за результатами розпізнавання нових об'єктів.
Аналіз науково-методичних підходів до моделювання процесу функціонування розвідувально-вогневих систем
Authors: Караванов О. А. , Купріненко О. М. , Майстренко О. В. , Баландін М. В. , Волков І. Д.
Published: March 2023

У статті проведено аналіз деяких відомих науково-методичних підходів до моделювання процесу функціонування систем військового призначення. Як відомо, процес бою є марковським випадковим процесом з дискретними станами та безперервним часом. Тому для моделювання бойових дій дуже часто використовують математичні моделі, які базуються на рівняннях Колмогорова. Математичні моделі, які базуються на системі диференційних рівнянь Колмогорова, дозволяють визначати імовірність перебування системи в тому чи іншому стані, врахувати внутрішні чинники, які впливають на функціонування системи. Однак ними не зручно користуватися при умовах, коли кількість станів, яких може набувати система, стає більше 10. Також така математична модель не враховує вогневий вплив, який здійснює протидіюча сторона. Для прогнозування процесів, які складно описати за допомогою диференційних рівнянь Колмогорова, використовуються математичні моделі, що базуються на методі динаміки середніх. Моделі, в основі яких лежить цей метод, з успіхом застосовуються для прогнозування бойових дій, в яких приймають участь великі групи тих чи інших елементів. Зміну чисельності протидіючих сторін в процесі бою зручно описувати системою диференційних рівнянь Ланчестера. Математичні моделі, які базуються на цих диференційних рівняннях, є досить гнучкими і дозволяють вивчати різноманітні бойові ситуації при здійсненні вогневого взаємовпливу протидіючих сторін. Однак у цих моделях не враховуються взаємозв’язки між підрозділами (зразками озброєння та військової техніки), що утворюються під час збройного протистояння. Одним з підходів, який, на думку авторів, дозволяє створювати математичні моделі процесу функціонування розвідувально-вогневої системи з врахуванням взаємозв’язків, які виникають у такій системі, є диференційні рівняння Лотки-Вольтерри, що досить широко використовуються при дослідженні динаміки росту популяції біологічних видів. За результатами проведених досліджень встановлено, що використання системи диференційних рівнянь Лотки-Вольтерри для створення  математичної моделі при дослідженні процесу функціонування розвідувально-вогневих систем є найбільш перспективним.

spp. in dogs, we used a convenience sampling of feces from 2 popula- tions of dogs; samples were tested with a lateral-flow assay (QC), a commercially-available direct fluorescent assay (DFA), and an inhouse PCR test using established primers. QC results were analyzed in 2 ways: 1) relative
to a reference standard that permitted comparative interpretation of DFA and PCR results; and 2) using Bayesian analysis for comparison independent of a reference standard. The QC test showed good specificity for the detection of Giardia according to both the reference standard (95%)
and the Bayesian analysis (98%). Similarly, specificity of the QC for the detection of Cryptosporidium was 95% according to the reference standard and 97% according to Bayesian analysis. However, the sensitivity of the QC test was much lower for both Giardia (reference standard,
38%; Bayesian analysis, 48%) and Cryptosporidium (25% and 40%, respectively). This study demonstrates that the QC test can be used to detect both Giardia and Cryptosporidium in dogs and that positive results can be accepted with confidence, whereas negative tests should
be confirmed through secondary testing methods.
La desterritorialización del lenguaje en Mare de llet i mel (2008) de Najat El Hachmi
Authors: El Morabit Sghire Zahra
Published: March 2023

Este artículo presenta un análisis de la novela Mare de llet i mel (2008) de Najat El Hachmi como ejemplo de literatura escrita por (hijos de) inmigrantes marroquíes en España. Específicamente, nos concentramos en la desterritorialización del lenguaje y los procedimientos que la autora moviliza para conseguir esta desterritorialización. El análisis se realiza en dos niveles. Por una parte, nos centramos en la forma, es decir, en el uso del lenguaje en la obra en sí. Por otra parte, se investiga cómo el uso de ciertas palabras y expresiones, al igual que los idiomas y su aprendizaje son tematizados en la novela. Las respuestas a estas preguntas se utilizarán para relacionar la escritura de El Hachmi con el concepto de ‘literatura menor’ como ha sido definido por Deleuze y Guattari.
Labour Market Restructuring and the Nature of Employment Relations in Nigeria
Authors:   Michael Okpara University of Agriculture, U. Ikeije Ugochukwu.
Published: March 2023

The Nigerian labour market has experienced remarkable structural changes in the last two decades following the dictates of globalisation. These changes manifested in the sectoral composition of employment, growth in the service and informal sectors, increased youth unemployment, increased self-employment, and growth in female labour participation. These developments equally affected employment arrangement by shifting attention from the traditional employment arrangement characterised by full-time permanent employment to a more flexible employment arrangement and non-standard jobs. This paper examined the emerging structural changes in the labour market and their consequences for employment relations in Nigeria. The paper adopted desk review methodology which involved analysis of secondary data from relevant research institutions, government agencies and corporate organisations. Evidence from the secondary data revealed that Nigeria has witnessed increased youth unemployment and underemployment, the decline in full-time permanent jobs, rise in casual/contract and part-time work, rise in female labour participation, rise in outsourcing and increase in labour shedding in the last two decades. The observed implications of these developments for employment relations include a decline in union density and bargaining power; a gradual increase in non-union representation; a shift in skill requirement; emphasis on employee loyalty and commitment; emphasis on work-life balance and flexible working hours. The paper, therefore, concludes that structural changes in the Nigerian labour market have affected traditional institutionalised employment relations, which are gradually being replaced by flexible and individualised employment relations.

Despite the numerous empirical studies that have been conducted on housing conditions, there is still very little research work carried out on military barracks life, the impact of the condition of the barracks’ accommodation on the soldiers’ social life and morale. Thus, thispaper presents a study onthe relationship between housing conditions, soldiers’ social life, and morale in Coral Barracks Nigeria and covers only the non-commissioned officers’ quarters. A quantitative method using a questionnaire survey was used with a sample size of 260.The data were analysed using descriptive statistics as well as parametric measurements. A total number of 194 questionnaires retrieved from the respondents were used in the analyses. Building services attributes had a strong and significant positive correlation. Moreover, neighbourhood and soldiers’ life correlate significantly, negative but weak, while physical housing attributes and neighbourhood attributes correlate significantly but negatively and weak with children's life. Neighbourhood attributes and soldiers’ morale recorded a significant, negative but weak correlation. In light of these findings, thisstudy recommends that astandard strategic plan for efficient barrack housing construction, management, and maintenance is designed.

Governmentregulationis one of the additional factorswhen examining the influence of land regulations by local authorities on the housing supply. Specifically, this factor is taken into consideration to investigate the effect of city-specific factors on housing supply elasticities. Some government regulation sub-factors usually proxied by index value obtained from the Wharton Residential Land Use Regulation Index (WRLURI). However, the index value is limited to a specific year and not distributed on short term or long-term basis due to data unavailability. Thispaper reviews the effect of government regulation sub-factors examined by the previous studies to develop a conceptual framework using time series data when the data is available. The findings of this analysis revealed that new studies should explore times series data for sub-factors such as number of restrictions,number of governing bodies, duration for subdivision approval, and the number of growth management policies.

Published: March 2023

Background: Neuroinflammation triggered by chronic cerebral ischemia-induced microglial pyroptosis is a significant contributor to vascular cognitive impairment. It has been shown that emodin possesses anti-inflammatory and neuroprotective properties, however, it’s potential molecular and signaling transduction pathway remains to be illuminated. This study researched the neuroprotective mechanisms of emodin focussing on emodin effects on lipopolysaccharide/adenosine triphosphate (LPS/ATP)-caused pyroptosis in BV2 cells and HT-22 hippocampal neurons. Methods: To explore the neuroprotective effect of emodin, Emodin was applied to BV2 cells, HT-22 hippocampal neurons, and BV2/HT-22 co-cultures stimulated with LPS/ATP to evaluate the cell morphology, levels of inflammatory factors, NLRP3 inflammatory inflammasome activity and focal pyroptosis-related protein expression, as same as neuronal apoptosis. Results: Emodin alleviated LPS/ATP-induced pyroptosis of BV2 cells by preventing the activity of the NLRP3 inflammasome and the cleavage of pyroptosis executive protein Gasdermin D (GSDMD). Furthermore, levels of interleukin (IL)-18, IL-1β and tumor necrosis factor (TNF)-α were reduced, the apoptosis of HT-22 hippocampal neurons was attenuated, and cell viability was restored. Conclusions: Emodin can antagonize microglial neurotoxicity by inhibiting microglial pyroptosis, thereby exerting anti-inflammatory and neuroprotective effects.
Survival of The Basing Arts of The Kajang Community in Global Challenges
Authors: Samidi Samidi , Husain Sarkawi B.
Published: March 2023

This article describes traditional arts dealing with global challenges. Globalization that makes it easy for everyone to express entertainment arts is a serious threat to Basing's traditional arts. The slowness of adaptation and regeneration further distances Basing's art from everyday life. The people of Kajang are trying to maintain it, but recently they have faced many obstacles. The mechanism that is still maintained is the relation of traditional art to the ritual of prayer for death. The purpose of this paper is to explain the relationship between traditioal art and rituals for the death and the constraints to inherit the art. This research used qualitative data that collected and analyzed based on village monograph, participant observations, and interviews. The observation is carried out during the Basing art performance at the death prayer ritual. The interviews were conducted on several people which proportionally representing social roles, including traditional community leaders, village government bureaucrats, teachers, youth art activists, village elders, and artists. The research found that restriction to the customary areas is only able to control people's behavior based on customary values and norms, but is not able to force residents to develop the Basing arts. However, the inheritance of arts faces obstacles because the people of Kajang are not able to carry out cadre of artists as successors and reinforcers of the existence of Basing art.
Performance Tasks as a Mediator to Communicating in English and for Enhancing Language Learner Engagement
Authors: Toyoshima Saeko
Published: March 2023

This paper discusses whether technology-based performance tasks
could be a mediator to communicating in English and enhance language learner
engagement. Through the research, this study investigated how low-proficiency
Japanese English-language learners could change their attitude toward
communicating in their target language by completing a performance task that
involved making and presenting a digital portfolio. The students had to mediate
between themselves linguistically and contextually when completing the
performance task. The study adopted two types of questions in a questionnaire:
one type involved a three-point Likert scale and the other included open-ended
questions about the performance task. Thirty-three students in the first and
twenty-eight in the second semester completed the questionnaire. The data from
the open-ended questions were analyzed qualitatively from a phenomenological
research perspective. The students’ comments on the task showed that they
positively engaged in the performance task throughout the two semesters by
reflecting on themselves as English learners, with some difficulty mediating
themselves in L1 and L2.
