The Engaged Humanities: Principles and Practices for Public Scholarship and Teaching
Authors: Jay Gregory
Published: January 2022

Will public scholarship and community engagement become central to revitalizing the humanities in the 21st century? Efforts to connect humanities research and teaching with projects to advance democracy, social justice, and the public good might take advantage of the latest episode of crisis, and even argue that they represent a strong new direction for revival. After a brief review of how definitions of the humanities have changed since the 1960s, the essay contends that the future of the humanities depends upon two interrelated innovations: the organized implementation of project-based engaged learning and scholarship, on the one hand, and the continued advancement of digital and new media learning and scholarship, on the other hand. A number of examples of engaged humanities practice are examined, their institutional obstacles analyzed, and the principles common to them enumerated. The conclusion focuses on how new media are changing the nature of “the public” once more, offering opportunities for different kinds of scholarship, teaching, and engagement.
Including Latino Communities in the Learning Process: Curricular and Pedagogical Reforms in Undergraduate Spanish Programs
Authors: Guillén Felisa
Published: January 2022

Since the fall semester of 2003, the Spanish program at Occidental College has been incorporating a community-service learning component in its intermediate and advanced language classes, as well as in all literature and culture courses. Based on the idea that culture-sensitive language instruction should include frequent and meaningful interactions with a language community, the Spanish program has developed a strong partnership with two local schools that have predominantly Latino enrollment. This mutually beneficial relationship helps college students improve their communication skills in Spanish while rendering a service to the Latino community through tutoring and mentoring programs, along with cultural presentations and artistic performances. Integrating the numerous activities resulting from this collaboration into the Spanish curriculum required rethinking program objectives, course structure, and responsibilities of the college, the faculty, and the students in the service-learning process. This article examines the pedagogical implications of embracing this teaching model at the departmental level, as well as the civic impact of the gradually increasing connections between the department and the neighboring Spanish-speaking communities. It also describes the program’s evolvement during four semesters of instruction; analyzes students’ reflections, community partners’ feedback, and departmental assessments; and evaluates the results, challenges, and benefits of becoming an engaged department.
Usability Enhancement of SMS Interface for Illiterate Users
Authors: Muhammad Waseem Iqbal
Published: January 2022

This article analyzes several User Interface (UI) designs and puts forward some more general design principles for interfaces designed for low-literate users. The results of this study highlight the importance of text-free interfaces compared to text-based interfaces for the illiterate and low-literate population. The study developed a Short Message Service (SMS) interface consisting of many design elements, including graphical icons, voice, and text reduction. The participants were more satisfied with the designed SMS interface as compared to the traditional text-based interface of SMS. We believe that if the user interface is appropriately designed, users will not need formal literacy, computer skills, or any external help to operate the application. It has been shown that an interface with minimal or no text but one or more graphics, audio, and digital components is helpful for users with low literacy rates.
Load Balancing in Cloud Computing Empowered with Dynamic Divisible Load Scheduling Method
Authors: Sohaib Ahmad
Published: January 2022

The need to process and dealing with a vast amount of data is increasing with the developing technology. One of the leading promising technology is Cloud Computing, enabling one to accomplish desired goals, leading to performance enhancement. Cloud Computing comes into play with the debate on the growing requirements of data capabilities and storage capacities. Not every organization has the financial resources, infrastructure & human capital, but Cloud Computing offers an affordable infrastructure based on availability, scalability, and cost-efficiency. The Cloud can provide services to clients on-demand, making it the most adapted system for virtual storage, but still, it has some issues not adequately addressed and resolved. One of those issues is that load balancing is a primary challenge, and it is required to balance the traffic on every peer adequately rather than overloading an individual node. This paper provides an intelligent workload management algorithm, which systematically balances traffic and homogeneously allocates the load on every node & prevents overloading, and increases the response time for maximum performance enhancement.
Comparison of Fault Simulation Over Custom Kernel Module Using Various Techniques
Authors: Muhammad Ejaz Sandhu
Published: January 2022

To test the behavior of the Linux kernel module, device drivers and file system in a faulty situation, scientists tried to inject faults in different artificial environments. Since the rarity and unpredictability of such events are pretty high, thus the localization and detection of Linux kernel, device drivers, file system modules errors become unfathomable. ‘Artificial introduction of some random faults during normal tests’ is the only known approach to such mystifying problems. A standard method for performing such experiments is to generate synthetic faults and study the effects. Various fault injection frameworks have been analyzed over the Linux kernel to simulate such detection. The following paper highlights the comparison of different approaches and techniques used for such fault injection to test Linux kernel modules that include simulating low resource conditions and detecting memory leaks. The frameworks chosen to be used in these experiments are; Linux Text Project (LTP), KEDR, Linux Fault-Injection (LFI), and SCSI.
An Efficient Classification Model using Fuzzy Rough Set Theory and Random Weight Neural Network
Authors: Rana Aamir Raza
Published: January 2022

In the area of fuzzy rough set theory (FRST), researchers have gained much interest in handling the high-dimensional data. Rough set theory (RST) is one of the important tools used to pre-process the data and helps to obtain a better predictive model, but in RST, the process of discretization may loss useful information. Therefore, fuzzy rough set theory contributes well with the real-valued data. In this paper, an efficient technique is presented based on Fuzzy rough set theory (FRST) to pre-process the large-scale data sets to increase the efficacy of the predictive model. Therefore, a fuzzy rough set-based feature selection (FRSFS) technique is associated with a Random weight neural network (RWNN) classifier to obtain the better generalization ability. Results on different dataset show that the proposed technique performs well and provides better speed and accuracy when compared by associating FRSFS with other machine learning classifiers (i.e., KNN, Naive Bayes, SVM, decision tree and backpropagation neural network).
D. I. MENDELÉIEV: UNHA APROXIMACIÓN AO CONTEXTO
Authors: Cid Ramon
Published: January 2022

A clasificación periódica de Mendeléiev, publicada por primeira vez en 1869, nun congreso celebrado en Rusia, permitiu que dese a coñecer aos seus colegas os resultados do seu traballo científico. A súa táboa posibilitou situar nun gráfico as importantes relacións químicas que había detrás dos elementos e achegarse ao comportamento xeral da materia. Trátase pois dunha ferramenta conceptual coa que predicir a existencia de novos elementos, permitindo o establecemento de relacións non recoñecidas e adquirindo o papel de memoria e sistema de organización. Nestas páxinas que seguen preténdese situar a Mendeléiev no tempo que lle te tocou vivir desde a perspectiva da Química. Non aparecerán, xa que logo, descricións extensas de carácter biográfico, agás aquelas que sexan estritamente necesarias en relación ao que se está a argumentar. Algúns dos apartados que conforman este artigo teñen como referencias fundamentais estudos anteriores levados a cabo por quen isto escribe, e que, por se tratar de descricións históricas, non teñen cambiado esencialmente. Para realizar o achegamento a ese contexto comezaremos por sinalar brevemente algunhas das controversias máis importantes que había na Química daquel tempo. Seguiremos cun percorrido pola presenza dos elementos químicos e a súa clasificación ao longo do S.XIX; lembraremos a celebración do primeiro congreso internacional de Quimica (Karlsruhe, 1860), que foi de gran transcendencia para un xove Mendeléiev, e remataremos cunhas breves notas relacionadas coa conexión sempre presente do gran químico ruso coa Táboa Periódica.

Not a few graduates from the Dirghantara Aviation Vocational School and Yappika Legok Vocational School who choose to continue their education at PPI Curug, but only a few graduates choose to major in Air Traffic Control. Due to the lack of interest in the graduates of the Dirghantara Aviation Vocational School and the Yappika Legok Vocational School, it is deemed necessary to have activities that can build interest in the Air Traffic Control major, namely through Community Service activities. The method used is face-to-face socialization at the PPI Curug Aviation Safety Building which is carried out in accordance with health protocols. The results of the service obtained are that it is hoped that students from the Vocational School know more about air traffic control and can spread knowledge to their friends so that students who have interest and curiosity able to understand more deeply the purpose of air traffic control. routinely either in the same location or in different locations with different target communities by other study programs. Socialization of professions in the field of aviation and study programs at PPI Curug to the public can be carried out with a wider scope nationally by collaborating with the Education Office online/video conference.
Tidak sedikit lulusan dari SMK Penerbangan Dirghantara dan SMK Yappika Legok yang memilih untuk melanjutkan pendidikannya di PPI Curug, namun hanya sedikit yang memilih jurusan Pemanduan Lalu Lintas Udara. Dikarenakan kurangnya minat lulusan SMK Penerbangan Dirghantara dan SMK Yappika Legok tersebut, maka dirasa perlu adanya kegiatan yang dapat menumbuhkan minat terhadap jurusan Pemanduan Lalu Lintas Udara yaitu melalui kegiatan Pengabdian kepada Masyarakat. Metode yang digunakan adalah sosialisasi secara tatap muka di Gedung Keselamatan Penerbangan PPI Curug yang dilaksanakan sesuai dengan protokol kesehatan. Hasil pengabdian yang didapatkan adalah diharapkan pelajar dari SMK tersebut dapat lebih mengenal mengenai pemanduan lalu lintas udara dan dapat menyebarkan ilmu terhadap temannya sehingga muncullah pelajar yang memiliki minat dan keingintahuan untuk dapat memahami lebih dalam maksud dari pemanduan lalu lintas udara.kegiatan pengabdian seperti ini dapat dilakukan secara rutin baik di lokasi yang sama maupun di lokasi berbeda dengan sasaran masyarakat yang berbeda oleh program studi lainnya. Sosialisasi mengenai profesi di bidang penerbangan dan program studi di PPI Curug kepada masyarakat dapat dilakukan dengan cakupan yang lebih luas lagi secara nasional dengan bekerja sama dengan Dinas Pendidikan secara daring/video conference.
Influence of Gasification Operating Parameters on Performance of the Nong Bua Dual Fluidized Bed Gasification System in Thailand
Authors: Siriwongrungson Vilailuck , Prasong Malinee , Hongrapipat Janjira , Rauch Reinhard , Pang Shusheng , Messner Michael
Published: January 2022

Gasification system performance generally depends on feed moisture content, activity of bed material, gasifier and combustor temperatures, and scrubber media. The tar concentration and gas composition of product gas are two indicators of the gasification system performance. In this research, the effects of gasifier temperature and the activity of bed material on the tar concentration and gas composition of the product gas produced from a dual fluidized bed (DFB) gasification system power plant were investigated. The DFB gasification system power plant is located in Nong Bua district, Nakhon Sawan province, Thailand. Two periods of gasification operation were examined. These two periods were when the olivine was freshy activated and then after a period of operation. The gasifier temperature had several peaks during the operation, which caused the product gas composition to fluctuate. When the olivine had been used for a period, the percentage of hydrogen was approximately 3% higher than when the olivine had been freshly activated, and a lower heating value was observed, which was probably due to lower heating value of hydrogen. The tar concentration was substantially lower when compared with the freshly activated olivine. When the olivine was used for a period, the average tar concentration was 56±22 mg/Nm3 (this is after 95 h continuous operating time) while the average tar concentration of the freshly activate olivine was 872±125 mg/Nm3 (which was after 34.5 h continuous operating time). It was concluded that the average tar concentration and gas composition were influenced by the activity of the bed material and the gasification temperature.

Authors: Muenmee Sutharat , Theepharaksapan Suthida , Boonnorat Jarungwit
Published: January 2022

This study investigated the possibilities of improving biogas yield from anaerobic digestion of refinery activated sludge (RAS) by optimizing the food to microorganism (F/M) ratio. Different F/M ratios of 0.25, 0.50, 1.00 and 2.00 were studied. The highest biogas production (147.98±7.40 ml/gvs), methane production (51.41±1.78 ml/gvs) and methane content (42.00±5.90%) were obtained from the F/M ratio of 1.00 followed by 0.50, 0.25 and 2.00, respectively. The phytotoxicity of biosolids that came from anaerobic digestion was also evaluated using three different types of seed (Vigna radiata, Brassica rapa and Lycopersicon esculentum) during this process. Increasing amount of RAS via increasing of the F/M ratio (0.25-1.00) stimulated plant development (GI>100) and reduced the phytotoxicity of RAS.

Globally, for the development of bitumen oils thermal steam treatment is considered, since this technology is considered the most effective, but it has a number of problems with the presence of clay minerals in the rock. When clay minerals come into contact with steam they swell, leading to a decrease in the permeability of the reservoir, and therefore a decrease in the final oil recovery. This work assesses the influence of clay mineralization content on the degree of oil displacement under thermal steam treatment by conducing filtration experiments. Steam injection experiments containing low oil saturations of less than 2% resulted in no oil displacement. A solvent based on aliphatic and polar fragments was tested to extract oil in such low-oil saturated systems. Keywords: steam injection; bitumen oil; clay minerals; solvent; oil displacement.
Why Choose Electrical Subjects? Profiling and Analyzing Motivations of Kuwaiti Pre-Service Teachers
Authors: Alanezi Ebrahim
Published: January 2022

The aim of this study was to determine factors that influence Kuwaiti pre-service teachers’ choice of Practical Electrical Subjects by profiling and analysing their motivations. Unlike previous studies that focused on the traditional conceptualisations of intrinsic, altruistic, and extrinsic motivations, this study uses the interpretive lens of Expectancy Value Theory which forms the foundation for the Factors Influencing Teacher Choice model to analyse and describe factors that influence the pre-service teachers’ career choice decisions. One hundred fifty-six pre-service teachers enrolled in a teacher education programme completed the Factors Influencing Teacher Choice survey on which they rated 25 motivational factors. T-tests and One-way ANOVA were used to examine differences based on gender and year of study. Self-efficacy beliefs, social utility value, time for family, job security and prior teaching and learning experiences were important career choice determinants. Fall back career was the least important motivational factor. Gender was found to significantly influence their career choice while year of study did not significantly influence their decision. In general, female pre-service teachers appeared to be more motivated to choose teaching electricity as a practical subject than males. The pre-service teachers’ year of the study showed significant variations only regarding social utility values and fallback career. The results of this study would contribute to existing literature on factors influencing pre-service teachers to choose a teaching career that involves vocational or practical subjects’ teachers. Some theoretical and practical implications are drawn for pre-service teacher education.

Published: January 2022

Introduction: Pheochromocytomas are neuroendocrine tumors capable of synthetizing, storing and releasing catecholaminergic hormones that may lead to life-threatening hemodynamic instability. The COVID-19 pandemic has increased the risks and perioperative complexity of the patients undergoing pheochromocytoma-associated adrenalectomy. This article discusses the use of adenosine for the management of hypertensive crisis during this intervention, as well as the need to individualize the suitable timing for surgery after recent COVID-19 infection.

Case presentation: This article discusses the case of a patient with a finding of right adrenal incidentaloma; further studies determined a metanephrines secreting pheochromocytoma. Following hospital admission for preoperative optimization, the eve of the procedure the patient developed an acute myocardial infarction and subsequently SARS-CoV-2 symptomatic infection. Intraoperatively, hypertensive peaks were managed with continuous adenosine perfusion. The patient was discharged after 48 hours.

Conclusions: Preoperative optimization positively influences the intraoperative management of patients with pheochromocytoma. The intraoperative use of adenosine allows for adequate and safe control of hypertensive crises. Each situation must be individualized in patients pending surgery, with a recent COVID-19 infection.

La identidad reelaborada en Galíndez de Manuel Vázquez Montalbán
Authors: Sevilla-Vallejo Santiago
Published: January 2022

La identidad es constantemente construida a través del discurso. En este sentido, podemos hablar de una “identidad discursiva” y de una “identidad en práctica” para referirnos al proceso lingüístico que forma nuestra personalidad» (Kanno y Stuart 238). La investigación que hace Muriel Colbert sobre la desaparición de Jesús de Galíndez es una reelaboración de la personalidad de este personaje, en la cual los hechos objetivos, las impresiones subjetivas y la ficción se combinan tanto en lo discursivo como en la práctica. En este estudio, se analiza cómo esta novela presenta que la construcción de la identidad es una ficción cultural fruto del empleo del lenguaje (Sevilla-Vallejo 2017b 291). Muriel Colbert pretende desvelar cómo fueron los últimos momentos de aquel a quien considera su héroe, pero los testimonios que recibe, tanto en entrevistas como de documentos, están constantemente transformando la imagen que tenía hasta el momento. Y lo que es más interesante es cómo los hechos y la ficción acerca de Galíndez también afectan a la identidad de la investigadora y del resto de personas que entran en contacto con él. La complejidad y contradicción de Galíndez reflejan la misma complejidad política en la que vivió y el choque entre los deseos y la realidad de cada uno de los personajes. Galíndez nos invita a una reflexión crítica más allá de los datos que se ofrecen (Bodenmüller 75) y a la búsqueda de la verdadera identidad en un contexto donde predomina la mentira y la ocultación.
Variable verb second in Norwegian main and embedded clauses
Authors: Westendorp Maud
Published: January 2022

Norwegian has verb second (V2) word order in main but not embedded clauses. Although as a first approximation V2 is a phenomenon characteristic of root clauses, it has long been known that it occurs also in a restricted set of embedded clauses in Norwegian, as in many, if not all, of the other North Germanic languages. Many Norwegian dialects in addition allow deviations from the standard V2 word order in main clause interrogatives. Hence, the asymmetric verb second pattern seems to break down in different ways in Norwegian. This study presents new data from a large-scale elicited production experiment targeting the placement of the finite verb in both main and embedded clauses in Norwegian. The distribution of deviations from the standard word order pattern, and the constraints on the environments where these are produced, will be of primary concern. While classic accounts of verb second analyse it as involving a macro-parameter, I will argue based on the collected production data that it is necessarily decomposed in several ways, with variation in both main and embedded clauses guided by clause type, assertion, and specific lexical items.
Verb placement variation in Swedish and Danish
Authors: Westendorp Maud
Published: January 2022

This article gives a summary of the Swedish and Danish data on verb placement in the Nordic Word order Database (NWD; Lundquist et al. 2019). The data were collected using an elicited production paradigm. I discuss variation in verb placement in Danish in four constructions: in embedded clauses with respect to adverbs (embedded V2), in main clauses with respect to preverbal and sentence-medial adverbs, and in embedded and main clause wh-questions. The Swedish data cover embedded clauses only. The Swedish and Danish results are discussed in direct comparison to the verb placement patterns observed in the other North Germanic languages covered in the NWD.
Shared authority in confirmation work in the Evangelical Lutheran Church in Denmark
Authors: Gunnertoft Anna Døssing
Published: January 2022

This article examines how authority is negotiated and shared by ministers engaged in confirmand work in the Evangelical Lutheran Church in Denmark. The ministers have formal authority establishing the framework and structure of the learning fellowship. They are also theological experts. However, authority is negotiated and attempt is made to share it in the confirmand class. The ministers do not wish to appear as all-knowing teachers as the confirmands may have had authentic experiences of Christianity and are, therefore, possible contributors to the learning process supplementing the ministers’ theological knowledge: the role of teacher and pupil are exchanged among the participants. In the analysis, the typology of Weber nuances the concept of authority as seen in three different cases.

Fadderrollen
Authors: Teistedal Vikre Marit Sofie
Published: January 2022

Hvordan kan kirken bidra til å styrke fadderrollen? Menigheten og hjemmet har tilgang til hverandre gjennom dåpsregister, dåpssamtale og invitasjon til trosopplæringssamlinger og kontinuerlige tiltak i menigheten. Fadderne som den tredje part i trosopplæringsansvaret kan oppleves mer utydelige i samarbeidet. Utgangspunkt for artikkelen er min masteravhandling med tittelen: «Et bidrag til en fadderteologi.» Med bakgrunn i min studie reflekterer jeg i denne artikkelen over hvordan informasjon og kontakt i forbindelse med dåp kan forbedres.
Income Security and the Perception of Disability Risk
Authors: Kawiński Marcin , Szumlicz Tadeusz
Published: January 2022

The concept of income security is almost 80 years old but its implementation, nevertheless, poses a serious social security problem. How is this problem seen today by those most concerned, family households? What is the perception of contingencies listed in the International Labour Organization’s (ILO) recommendation? Human responses to risk (behaviour under risk) depend primarily on a perception of risk and disability risk is not different in this respect. It is a major social risk, a part of the list of social risks, and tends to be critical due to financialization and liabilities. This paper aims to find determinants for differences in the perception of disability risk in Poland. The research covers particular determinants and employs qualitative and quantitative methods to analyse such determinants. The qualitative study suggests that the risk of disability is not a primary consideration. The perception of that risk seems to be diverse. Pending liabilities are perceived as arising primarily due to unemployment rather than the lack of fitness for work. An analysis of quantitative data shows statistical importance of chosen determinants (gender, experience regarding disability within family, age, the level of education, and self-estimation of financial situation). However, their significance is limited. Age and education level seem to be most prospective. Young and highly educated people tend to perceive disability risk as relatively low. These are also the people who face the most significant financial consequences of disability.
Factors Influencing the Consumer Tendency to Use Mobile Instant Messaging (MIM): A Mixed Method Study
Authors: Cruz-Cárdenas Jorge , Guadalupe-Lanas Jorge , Ramos-Galarza Carlos , Palacio-Fierro Andrés
Published: January 2022

Mobile instant messaging (MIM) is currently one of the most influential areas of technology. MIM applications have experienced substantial growth in the number of users; however, research on consumer behavior regarding the use of these applications is relatively scarce. The present study seeks to fill this gap, with the objective of identifying, understanding, and establishing the determinants of MIM use. The current study takes place in Ecuador, a developing Latin American country, and focuses on WhatsApp, the leading MIM application. The study is based on a sequential exploratory mixed method design with 25 in-depth interviews and a subsequent survey of 504 adults. The qualitative phase allows the establishment of a qualitative theoretical model in which the core category studied to understand the tendency of people to use WhatsApp is the perception of its utility. The qualitative phase and a literature review are the basis for formulating the study hypotheses. Finally, the quantitative analysis, based on structural equation modeling, yields the conclusion that network externalities, perceived usefulness, and perceived ease of use are the constructs that explain the tendency of individuals to use WhatsApp.
Cautionary Note About the Herfindahl-Hirschman Index of Market (Industry) Concentration
Authors: Kvålseth Tarald O.
Published: January 2022

The Herfindahl-Hirschman index (HHI) appears to be the most widely used index of market or industrial concentration. It is a summary measure that indicates the degree of competition, market power, and efficiency within a market or an industry. The HHI is also used by government agencies when evaluating potential violation of antitrust laws and regulations. As emphasized in this paper, and in spite of its several desirable properties, HHI has one serious imitation: it lacks the value-validity property. Lacking this property, caution has to be exercised when using HHI in order to avoid invalid and misleading results and conclusions. A corrected index is developed as a simple reformulation of HHI. Since this new index formulation meets the conditions imposed by the value-validity property to a high degree of approximation, and has other desirable properties comparable to those of HHI, the corrected index can safely be used to make various types of comparisons that are true and valid representations of market (industry) concentration. Numerical data are provided to support and exemplify the use of the corrected index.
Analysis of the Internationalization and Value Chain Activities in Chilean Enterprises
Authors: Vallina-Hernández Ana María , de la Fuente-Mella Hanns , Fuentes-Solís Rodrigo
Published: January 2022

An open economy inserted in an environment with increasing participation of global value chains, such as the Chilean economy, requires information about how its business integrates into international markets. The contribution of this study is that it evaluates the stages and patterns of Chilean firms’ internationalization by using a value chain activities framework, identifying four categories. The intensity of upstream and downstream business activities allows classifying the mode in each of the four categories. Members of the Sociedad de Fomento Fabril (SOFOFA) answered the survey design for this study. Results illustrate companies' behavior concerning international trade and foresight of further critical issues.

Authors: Pinheiro Denis Pinto , Figueiredo Eduardo
Published: January 2022

Microservice architectural style is becoming popular in the development of modern applications, but symptoms of good software quality still remain. Code smells and architectural smells (called Bad smells) are identifiable characteristics in software indicating a poor design which might affect the maintainability and understandability. The goal of this master thesis proposal is to present the plan of a review of the literature on the subject of Microservice BadSmells (MBS) and related MBS detection tools (MBSDT), consolidating the knowledge by compiling a full characterized data set of current identified MBS and evaluate the effectiveness of related existing detection tools.
