Neutral Observers or Advocates for Societal Transformation? Role Orientations of Constructive Journalists in Germany
Authors: Krüger Uwe , Beiler Markus , Gläßgen Thilko , Kees Michael , Küstermann Maximilian
Published: July 2022

Since the 2010s, a new type of journalism has emerged, especially in North America and Western Europe, called constructive journalism. Its basic idea is to complement classic problem-centered reporting by covering problem-solving approaches that could inspire the recipients. It has been harshly criticized, especially for its alleged proximity to advocacy or activism. To clarify the role orientations of the protagonists of this trend, a survey of all German journalists that call themselves constructive or solution-oriented was conducted (n = 79). The results show that constructive journalists are as diverse in age as the total of all journalists in Germany, but tend to be more women journalists, freelancers, formally higher educated, and politically leaning toward green and left-wing positions. Regarding role orientations, the field of constructive journalism not only represents a new facet of the entire journalistic field but also consists of several nuanced approaches itself: In factor analysis, we found eight role dimensions, of which the most important were the Social Integrator, the Transformation Agent, the Active Watchdog, the Emotional Storyteller, and the Innovation Reporter. In comparison to the average German journalist, the German constructive journalist shows stronger ambitions to control political and business elites, to motivate people to participate, and to contribute to social change. This can be explained as a countermovement not only to a possible negativity bias in the news but also to an increased attitude of detachment in German newsrooms.
United in Grief? Emotional Communities Around the Far-Right Terrorist Attack in Hanau
Authors: Medeiros Débora , Makhashvili Ana
Published: July 2022

Drawing on theories of affect, emotion, and new institutionalism, we analyze discourse around the right-wing terrorist attack in Hanau, Germany, to identify the different ways in which emotions and affect circulate on legacy media and Twitter and how they help establish varying emotional communities. Building upon an understanding of journalism as an affective institution, our article takes a close look at how journalism attempts to assert its role in public spheres not only by circulating information but also by providing emotional interpretations of events. Journalism’s emotional interpretations, however, do not remain unchallenged. With the emergence of the hybrid media system, users engage in various forms of interaction on social media platforms, forming “affective publics” by connecting through their affective reactions to current issues and events. In these interactions, distinct emotional communities may emerge, built around performative, political emotions. Our data comprises various news shows aired on the German public service broadcaster ARD as well as a dataset of tweets about #Hanau that were collected in the immediate aftermath of the attack. The results of our mixed-methods analysis reveal that different performances of grief played a central role both on TV news and on social media. On TV, grief was nationally connotated and aimed at uniting Germany’s population. On social media, it fueled anti-racist activism, as seen on the hashtag #SayTheirNames, honoring the victims of the attack.

Published: July 2022

Distance learning is not the product of the modern world as some may think; its origins go back to the 1720s with the very first experience of correspondence learning. Nevertheless, the concept of online learning, on the other hand, is the product of the modern digitalized world since its principal key element is the Internet. In this paper, we are going to clarify the ambiguity underlying two interrelated but different concepts which are ‘distance learning’ and ‘e-learning’. Then, we will trace the historical background of distance education in the world and in Algeria. In the end, we will present the results of a descriptive study that was conducted through an online questionnaire, and which targeted first-year students of the Department of the Arabic Language and Literature, University of Oran1 Ahmed Ben Bella. The purpose of this opinion poll was to reflect students’ impressions and evaluate their first and unique experience of learning English electronically during the COVID-19 pandemic.
Osmanlı Donanması’ndaki Yerli İmkânlarla Bir Muharebe Gemisi İnşa Deneyimi: Abdülkadir
Authors: Mercan Evren
Published: July 2022

1897 Osmanlı - Yunan Harbi’nin acı deneyimi 93 Harbi sonrası kıyı savunma odaklı Osmanlı Donanması’nın operasyonel yetersizliğini gün yüzüne çıkarmıştı. Bu yetersizliğin karşısında Osmanlı devlet ricali iddialı bir donanma programını hayata geçirerek bununla başa çıkmaya çalıştı. Donanma programının içeriğinde yurtdışından temin edilecek muharebe gemisi, kruvazör ve muhrip dışında devletin kendi imkân ve kaynaklarıyla Tersâne-i Âmire bünyesinde inşa edeceği bir muharebe gemisi projesi de bulunmaktaydı. Daha sonra Abdülkadir ismi verilecek 8,100 tonluk 103 metre boyundaki bu devasa platform, Osmanlı donanma envanterindeki en güçlü harp gemisi olması hasebiyle iddialı bir projeye karşılık gelmekteydi. Uzun bir sürenin ardından tersane bünyesinde inşasına girişilen ilk büyük evsaftaki muharebe gemisi olan Abdülkadir, uzun süren inşa dönemi teknik ve maddi yetersizliklerin yanında, idari karmaşa ve plansızlık yüzünden tamamlanamamış; yıllarca gövde iskeletiyle kızakta atıl kalmıştı. Nihayetinde 1906’da inşası durdurulmak zorunda kalınmış, 1909’da gemi hurdaya ayrılmıştı. İnşası tamamlanabilseydi Osmanlı Donanması’nın caydırıcılığına belirgin katkı sağlayacak olan Abdülkadir’in bir fiyasko ile sonuçlanan inşa süreci dönemin siyasi, askerî ve iktisadî durumunun da tecessümü gibidir.
Group Opinion Polarization in Conditions of Moral Choice Uncertainty
Authors: Lebedev A.N.
Published: July 2022

There are a huge number of phenomena about which people might have stable opposing opinions. In social psychology, this is called group polarization. The most difficult here are the problems of moral choice, which do not have unambiguous solutions and often divide people in a group into two irreconcilable camps. Numerous studies in this direction are being conducted on the basis of the so-called “Kant-Constant paradox”. The presented experiment, according to the authors, confirms the hypothesis that in the process of making a decision in a group discussion, the subjects undergo a restructuring of value judgments not only at the level of consciousness, but also at the unconscious level. The results of the study were explained on the basis of V.M. Allakhverdov’s theory of consciousness, according to which rational judgments and decisions can be carried out not only consciously, but also unconsciously. The study was conducted in the form of an online discussion in 4 experimental groups. In total of 106 people took part in it. A list of specially selected Russian folk proverbs was used as a test material. It was found that after a discussion that requires a public statement of the respondent about his moral choice, there may be a significant shift in the assessments of his attitude to proverbs, both related to the task being performed and not directly related to it, which the participant of the experiment may not realize.

Identifying Arrhythmias Based on ECG Classification Using Enhanced-PCA and Enhanced-SVM Methods
Authors: Philip Akhil Mathew , Hemalatha Dr. S
Published: July 2022

The "Cardio Vascular Diseases (CVDs)" had already attained worrisome proportions in both advanced and emerging nations in recent times. Physically inactive behaviors, altered eating, and occupational routines, and reduced daily fitness were all recognized as crucial contextual elements, in addition to genetics. Considering CVDs have such a significant morbidity and mortality, accurate and early diagnosis of cardiac disease by "ElectroCardioGram (ECG)" allows clinicians to decide suitable therapy for a multitude of cardiovascular disorders. The interpretation of ECG signal is an important bio-signal processing area that involves the application of computer science and engineering to detect and visualize the functional status of the heart. Therefore, in the present work, a detailed study on ECG signals denoising and abnormalities detection using different techniques were performed. Annoying distortions and noisy particles are common in ECG signals. The "Biased Finite Impulse Response (BFIR)" preprocessing filtering is employed in this research to eliminate the noises in the raw ECG signals. The "Nonlinear-Hamilton" segmentation method is employed to segment the 'R' peak signals.  To decrease the extraneous features included in the segmented ECG data, the innovative "Enhanced Principal Component Analysis (EPCA)" was applied for feature extraction. A unique "Enhanced version of the Support Vector Machine (ESVM)" framework with a "Weighting Kernel" based technique is proposed for classifying the ECG data. The 'Q', 'R', and 'S' waves in the given ECG data will be identified by this framework, allowing it to characterize the cardiac rhythm. The evaluation metrics of the EPCA-ESVM proposed method is comparatively analyzed with our previous approach EPSO. To estimate the results for the dataset from MIT-BIH it was experimented with by the EPSO and the EPCA-ESVM methods focused upon different parameters such as Accuracy, F1-score, etc. The final findings of the EPCA-ESVM method were good than the EPSO method in which the accuracy is higher even though unbalanced data were present.
Further notes on J. R. R. Tolkien’s photostats of The Equatorie of the Planetis (MS Peterhouse 75.I)
Authors: Cossio Andoni
Published: July 2022

Andoni Cossio proposes in a recent article the addition of The Equatorie of the Planetis (c. 1393) in MS Peterhouse 75.I to

“Section A” of Oronzo Cilli’s Tolkien’s Library: An Annotated Checklist (2019). However, Cossio fails to specify the folios of MS Peterhouse 75.I to which the photostats in Tolkien VC 277 correspond. A detailed descriptive list of the photostats that J. R. R. Tolkien received from Derek J. Price could be useful in the understanding of the type of assistance Tolkien offered to Price and R. M. Wilson at the time they were preparing an edition of The Equatorie of the Planetis(1955). This note will supply that missing information as well as speculate about the nature of Tolkien’s contribution to the project and its implications. Tolkien devoted considerable attention to the study of Geoffrey Chaucer’s language, and he may have been aware, after careful examination of The Equatorie of the Planetis, that its attribution to Chaucer rested on inconclusive evidence. This view of course would have challenged Price and Wilson’s assumptions and it may explain why we know so little about Tolkien’s involvement.
Effective laser correction of multiple teleangiectasia on the face
Authors: Sustretov Vyacheslav A.
Published: July 2022

Telangiectasia is a persistent dilation of small-caliber skin vessels (arterioles, venules, capillaries) of a non-inflammatory nature, manifested by polymorphously convoluted and dilated vessels. Telangiectasias are classified according to the cause of occurrence, the form of changes in the vascular pattern, time and localization, and are also divided into 3 large groups ― essential (idiopathic); symptomatic in various diseases; congenital and hereditary syndromes and diseases accompanied by vascular anomalies. In addition, telangiectasias can be single and multiple, located locally or disseminated, differ in shape, location, color; sometimes they bleed. Differential diagnosis is carried out with flaming and telangiectatic nevus; multiple senile, glomerular, bundle angiomas; Fabry angiokeratoma, Sivatts poikiloderma. In addition, telangiectasia is a typical clinical symptom in the erythematous-telangiectatic form of rosacea, systemic scleroderma, discoid lupus erythematosus, nodular form of basal cell carcinoma, hyper- and atrophic scars, late radiation dermatitis.
The article describes a case from the clinical practice of effective treatment of telangiectasias on the skin of the face using a neodymium crystal laser, which is of interest, among other things, due to the complexity of diagnosis within the existing International Classification of Diseases 10 revision, therefore the diagnosis is made syndromally based on macro- and microscopic morphological features. In addition, there is no single approach to the treatment of the pathology in question. External therapy, as well as systemic drugs, are often ineffective, sclerotherapy and exposure to a high-power vascular laser have a more pronounced clinical effect (broadband light; neodymium laser; pulsed dye laser; alexandrite, diode, ruby laser). Based on the recommendations of the laser manufacturer on percutaneous vascular coagulation and modern theories about the pathogenesis of telangiectasias, an algorithm for treatment with a long-pulse laser with a wavelength of 1064 nm on a clinical example is proposed. By prescribing a course of treatment of vascular malformation by laser percutaneous coagulation, we expect to obtain the destruction of pathologically dilated vessels of the papillary and mesh layer of the dermis by gluing the walls of the vessels (preferably) or complete thrombosis of their lumen while maintaining the structures of the dermis and epidermis intact. Laser percutaneous vascular coagulation has demonstrated excellent treatment results in a short period of time, significantly reducing the number of pathologically altered vessels. The rehabilitation period after laser coagulation of blood vessels did not exceed 3 days and was manifested by moderate edema of soft tissues in the area of laser exposure, hyperemia and single petechial hemorrhages, which resolved themselves.
Laser coagulation of skin telangiectsies is a highly effective method with a long-term clinical effect.
Real-Time Earthquake Detection and Alerting Behavior of PLUM Ground-Motion-Based Early Warning in the United States

We examine the real-time earthquake detection and alerting behavior of the Propagation of Local Undamped Motion (PLUM) earthquake early warning (EEW) algorithm and compare PLUM’s performance with the real-time performance of the current source-characterization-based ShakeAlert System. In the United States (U.S.), PLUM uses a two-station approach to detect earthquakes. Once a detection is confirmed, observed modified Mercalli intensity (MMI) distributions are forecast onto a regular grid, in which the preferred alert regions are grid cells with MMI 4.0+ forecasts. Although locations of dense station coverage allow PLUM to detect small (M < 4.5) earthquakes typically not considered for EEW in the U.S., a PLUM detection on a small earthquake does not always generate an alert. This is because PLUM alerts are determined by current shaking distributions. If the MMI 4.0+ shaking subsides prior to detection confirmation by shaking at a second neighboring station, the prior MMI 4.0+ information will not be in the alert forecasts. Of the 432 M 3.0+ U.S. West Coast earthquakes in 2021, 33 produced ground motions large enough to be detected by PLUM. Twenty-four generated MMI 4.0+ PLUM alerts, whereas ShakeAlert issued public EEW alerts for 13 of these earthquakes. We compare PLUM and ShakeAlert alert regions with ShakeMap and “Did You Feel It?” intensity distributions. Because PLUM alert regions surround stations observed to have strong ground motions (regardless of earthquake magnitude), PLUM alerts reliably include locations that experience significant shaking. This is not necessarily the case for ShakeAlert alert regions when there are large errors in magnitude or epicenter estimates. For two of the largest earthquakes in our real-time dataset, the M 6.0 Antelope Valley and M 5.1 Petrolia earthquakes, the inclusion of PLUM would have improved real-time ShakeAlert performance. Our results indicate that incorporation of PLUM into ShakeAlert will improve the robustness of the EEW system.

Published: July 2022

Three-dimensional (3D) bioprinting technology is an effective method for exploring the biological functions of hepatocytes by building biomimetic 3D microenvironments. Various hepatic tissue models have been developed for disease modeling, drug screening, and tissue regeneration using 3D bioprinting technology. Human-induced pluripotent stem cells (hiPSCs) are a promising cell source for the generation of functional hepatocytes for bioprinting. In this study, we introduced hiPSC-derived hepatocytes (hiPSC-Heps) as mature hepatocytes for the bioprinting of a 3D hepatic tissue model. The 3D-printed (3DP) model facilitated the formation of hiPSC-Hep spheroids with higher viability and proliferation than the commonly used non-printed sandwich-cultured model. hiPSC-Heps in the 3DP model exhibited higher mRNA expression of liver-specific functions than those in the two-dimensional-cultured model. Moreover, enhanced secretion of liver functionrelated proteins, including α-1-antitrypsin, albumin, and blood urea nitrogen, was observed in the 3DP model. For the evaluation of acetaminophen-induced hepatotoxicity, the 3DP model exhibited a favorable drug response with upregulation of the drug metabolism-related gene cytochrome P450-1A2 (CYP1A2). Overall, the bioprinted hepatic tissue model showed great biofunctional and drug-responsive performance, which could be potentially applied in in vitro toxicological studies.

Published: July 2022

Additive manufacturing (AM) technologies have disrupted many supply chains by making new designs and functionalities possible. The opportunity to realize complex customized structures has led to significant interest within healthcare; however, full utilization critically requires the alignment of the whole supply chain. To offer insights into this process, a survey was conducted to understand the views of different medical AM stakeholders. The results highlighted an agreement between academics, designers, manufacturers, and medical experts, that personalization and design control are the main benefits of AM. Interestingly, surface finish was consistently identified as an obstacle. Nevertheless, there was a degree of acceptance that post-processing was necessary to achieve appropriate quality control. Recommendations were made for extending the use of in situ process monitoring systems to support improved reproducibility. Variations in the future vision of AM were highlighted between stakeholder groups and areas of interest for development noted for each stakeholder. Collectively, this survey indicates that medical stakeholders agree on the capabilities of AM but have different priorities for its implementation and progression. This highlights a degree of disconnection among the supply chain at a ground level; thus, collaboration on AM specific standards and enhancement of communication between stakeholders from project inception is recommended.
Tannic Acid-mediated Multifunctional 3D Printed Composite Hydrogel for Osteochondral Regeneration
Authors: Dong Lanlan , Han Zhengzhe , Li Xiang
Published: July 2022

Hydrogels have become an attractive option for tissue repair. A novel multifunctional hydrogel was developed using a two-step method involving photopolymerization and tannic acid (TA) solution incubation. The mechanical properties of this hydrogel were enhanced by the multi-hydrogen bond interaction between the TA and N-acryloyl glycinamide/gelatin methacrylate (NAGA/GelMA). The compressive modulus was doubled. The compressive strengths of the hydrogel were 5.5 MPa. The swelling rate was reduced by a factor of three. The adhesion strength of the composite hydrogel reached 80 KPa. The TA-mediated NAGA/GelMA/Laponite composite hydrogel exhibited excellent anti-fatigue and anti-oxidation properties, as well as printability. In vitro experiments indicated that the TA-mediated hydrogel facilitated the proliferation of bone marrow mesenchymal stem cells and osteogenic and chondrogenic differentiation. The developed multifunctional composite hydrogel has great potential for osteochondral defect repair under osteoarthritis conditions.

Fertility preservation is becoming a clinical duty in practice. Three-dimensional (3D) bioprinting technology is potentially realize ovarian morphological repair and reproductive endocrine function rebuild. There is no published work on 3D bioprinting ovary using a decellularized extracellular matrix (dECM)-based bioink, though dECM is the preferred matrix choice for an artificial ovary. The study aimed to explore swine ovarian dECM-based bioink to fabricate 3D primary ovarian cells (POCs)-laden structures for mouse ovarian failure correction. In this study, the ovarian dECM was converted to dECM-based bioink by dECM solution mixed with a seaweed gelatin blend solution of bioink that was characterized using scanning electron microscopy, circular dichroism, rheology, hematoxylin and eosin staining, and immunohistochemistry. The 3D scaffolds were, then, printed with or without POCs by the extrusion 3D bioprinter. The laden POCs viability was detected with the live/dead assay kit. A female castrated mouse model was established, and the mice were treated with five different methods. The results revealed that the 3D scaffold encapsulating POCs group had more positive signals in neoangiogenesis, cell proliferation and survival than the 3D scaffold group, and ensured sex hormone secretion. Meanwhile, the expression of germ cells in the 3D scaffold encapsulating POCs group was more intensely than the non-printed hydrogel encapsulating POCs group. The work shows that the 3D bioprinting ovary employing ovarian dECM-based bioink is a promising approach for ovarian failure correction.

Published: July 2022

Artificial bone materials are of high demand due to the frequent occurrence of bone damage from trauma, disease, and ageing. Three-dimensional (3D) printing can tailor-make structures and implants based on biomaterial inks, rendering personalized bone medicine possible. Herein, we extrusion-printed 3D silk fibroin (SF) scaffolds using mixed inks from SF and sodium alginate (SA), and post-mineralized various calcium phosphates to make hybrid SF scaffolds. The effects of printing conditions and mineralization conditions on the mechanical properties of SF scaffolds were investigated. The SF scaffolds from ~10 wt% SF ink exhibited a compressive modulus of 240 kPa, which was elevated to ~1600 kPa after mineralization, showing a significant reinforcement effect. Importantly, the mineralized SF 3D scaffolds exhibited excellent MC3T3-E1 cell viability and promoted osteogenesis. The work demonstrates a convenient strategy to fabricate SF-based hybrid 3D scaffolds with bone-mimetic components and desirable mechanical properties for bone tissue engineering.

For almost two years now, the world has faced the COVID-19 pandemic whereby face-to-face learning has changed to online learning. The most crucial component is that science students' abilities have not appropriately developed, particularly in critical thinking skills. Hence, this research aimed to examine the effectiveness of an Inductive Model during online learning to enhance science students' critical thinking skills. This quasi-experimental with explanatory mixed-method design involved pre-test and post-test sessions followed by a focused group interview. Sixty science students were divided into two groups: the control group and the treatment group. The control group (n = 30) was taught via online learning without using an Inductive Model, while the treatment group (n = 30) was taught via online learning using an Inductive Model. The results showed that the science students’ critical thinking achievement in the treatment group significantly improved based on the post-test results. The Levene's test showed that the pre-test scores of the two experimental groups were homogeneous before the experiment was conducted [F (1, 58) = 2.757, p > 0.05]. In the qualitative aspect, this study also found that students had an enjoyable session and were motivated (more interested, and fascinated) through the inductive learning session, and improved their critical thinking skills. In conclusion, science teachers need to be creative and competent in teaching and learning strategies to reinforce students' critical thinking skills.

Published: July 2022

Online education assumed an increasing relevance in the last two years in face of the successive pandemic-motivated lockdowns by SARS-Cov-2. Considering the potential strengthening of this type of education in Portugal, particularly in the context of higher education, this study aims to analyze the perspective of students on three vectors of the online education quality, namely the overall quality of classes, the assessment process, and the online teaching tools available. Students' perceptions regarding these vectors will be assessed from the demographic variables, and factors that underlie online education according to the literature. The research is based on a quantitative methodology. Data was carried out through a structured questionnaire applied online, which had the answers of 2,107 students from different courses and higher education institutions in Portugal in July 2020. Factor analysis and logistic regression were used. The findings identified a significant association between the three vectors of the quality of online education proposed, and the factors usually proposed in the literature that are part of the student, instructor, and technology dimensions. It is expected that this research provides the inputs to the different players involved either in the implementation or development of courses offered through online learning in Portugal.

Authors:   Taylor's University, 47500 Subang Jaya, Malaysia, Lim Chee Leong , She Long , Hassan Nurhanim
Published: July 2022

This study aims to compare students’ preferences for pre-recorded videos and live lectures, and to establish the relationship between these two types of online lectures on students’ online learning satisfaction and academic achievement during the pandemic. This study is quantitative in nature and involved 552 respondents who are undergraduate students from four faculties in one of the private universities in Malaysia. Structural Equation Modeling (SEM) was used to analyse the proposed hypotheses. The results show that the pre-recorded video lecture has a positive effect on students’ online learning satisfaction in three faculties, i.e., Social Science, Business and Medical Science, whereas, in the faculty of Innovation and Technology, the live online lecture has a significant effect on their students’ online learning satisfaction. However, students from all four faculties responded that both pre-recorded video lectures and live online lectures did not significantly improve their academic achievement. The findings of this study provide a guideline for academics in their online pedagogical consideration, especially in deciding the type of online lecture preferred by their students which has contributed to their online learning satisfaction, thus improving the overall quality of the online learning experience.

The research was conducted to examine how an English lounge program at a university affected students’ speaking ability and their attitude toward their foreign teachers and to determine if there were significant differences in the effects between the program delivered face-to-face and online as perceived by the two groups of respondents – students and teachers. This study is a descriptive-comparative survey research. Frequency analysis, mean comparison analysis, t-test, correlation analysis, and regression analysis were the statistical tools used. The computed mean values show that as perceived by the participants, the program, implemented face-to-face and online; improved the students’ speaking ability and their attitude toward their foreign teachers to a great extent. Results have shown that as perceived by the participants, both versions of the program improve the students’ speaking ability and their attitude toward their foreign teachers and that students’ attitude toward foreign teachers is strongly correlated to (and significantly influences) the development of their speaking ability. The findings convey the importance of establishing rapport between students and teachers in the development of the speaking ability of students. It also reveals that online English lounges are as effective as when they’re implemented face-to-face.

Published: July 2022

The emergence of digital learning has reshaped English language teaching and learning. Thus, technology-based language learning gained extensive attention due to its benefits. However, the trends of using these digital platforms in English language learning in the Arab EFL context have not been sufficiently scrutinized. Therefore, this study investigates EFL students’ use of digital platforms for learning purposes, attitudes, and digital literacy. Also, the study examines the correlation between students’ digital literacy skills, attitudes, and using digital platforms for learning purposes. The study used a quantitative research design by collecting data from 80 EFL who were selected randomly to answer a survey questionnaire. Data were analysed using SPSS 23.0 software. The results revealed that students showed a high level of attitudes, a moderate level of digital literacy skills, and a moderate level of using digital platforms for learning purposes. The findings showed a negative non-significant relationship between students’ use of digital platforms in learning the English language, digital literacy skills, and attitudes. Based on the results, attitude and digital literacy do not predict the use of digital platforms for learning English. This study contributes significantly to the limited studies that examine the use of the digital platform for pedagogical purposes. The results recommend further investigation in addressing factors that hinder the use of digital platforms in EFL classrooms.

Published: July 2022

There is no universal response for institutions in higher education on how to handle the continuity of education during the radical transformation all across the world during COVID-19. Online learning is often used as a synonym for emergency remote teaching, however, both methods have fundamentally different characteristics that differ in implementation and effectiveness. This study aims to investigate student perceptions concerning online learning and emergency remote teaching (ERT) during the global pandemic. An importance-performance analysis (IPA) was used to determine the perceived satisfaction of undergraduate students. This mixed-method study expands earlier research addressing concerns with ERT and adds to the body of knowledge by investigating how ERT is perceived by university students in Northeastern Thailand. Responses from a self-administered survey were collected and analyzed (n=287). Based on descriptive analysis, it was decided to conduct 14 unstructured interviews to investigate particular findings more thoroughly. The study identified that the students largely view ERT as inferior compared to traditional classroom teaching. Moreover, the students claimed both lack of social interactions with peers and inability to seek academic support as the primary reasons. This study informs educators about student perceptions and preferences during these extraordinary circumstances of uncertain duration.

In this paper, the numerical results of the study on geothermal-air heat exchanger in dry areas of Algeria (Ghardaia region) were presented. Computational fluid dynamics equations were solved using our specific code compilated with Fortran. The outputs of the numerical calculations were compared and validated with the experimental results and the outputs of a commercial CFD code. In these conditions, our results present good agreements with an error not exceeding 2%. By using our numerical model, we have calculated the optimum length, the internal diameter, the air velocity of the pipe in winter and summer periods and have determined the optimum depth at different depths. The comparison of two types of pipes making material (PVC and PEHD) has taken into account the characteristics of the Ghardaia-Algeria region (specific heat capacity, density, thermal conductivity and temperature) of the soil. The obtained results proved that the chosen model gives a satisfactory agreement in all the studied variables.

Published: July 2022

Currently, there are several problems related to practicum report collection inthe electrical engineering laboratory at the Muhammadiyah University of Sidoarjo. The firstproblem is the presence of crowds during practicum report collection that have theirdangers, specifically during the Covid-19 pandemic. Another problem is the absence oflaboratory assistants in the electrical engineering laboratory when there are students whowill collect reports. A tool that can receive practicum reports was made from these problems,and it can be monitored remotely by a laboratory assistant. By putting an RFID card to theRFID sensor on the box so that the solenoid can open the box door and the student can putthe report into the box. At the same time, ESP32-CAM takes pictures of students collectingthe report. Then, notification in the form of photos and student information will be sent tothe laboratory assistant through the Telegram application. After the report is placed into thebox, the UV Sterilizer will turn on to disinfect the report. The expectation of making this toolis to facilitate the collecting report process of practicum results and reduce the crowd in thelaboratory.

Latar Belakang: Permasalahan pengelolaan keuangan daerah masih sering terjadi. Terdapat temuan yang selalu berulang-ulang di setiap tahunnya. Kota Pekanbaru menjadi salah satu kota yang temuan kasus atas ketidakpatuhan perundang-undangannya sebesar 8%. Dari tahun 2016 sampai dengan tahun 2020, laporan keuangan pemerintah kota Pekanbaru mendapatkan opini wajar tanpa pengecualian (WTP), namun di setiap tahunnya Badan Pemeriksaan Keuangan selalu menemukan adanya permasalahan pengelolaan keuangan yang tidak tertib.Tujuan: Riset ini bertujuan menyediakan fakta empiris tentang determinan optimalisasi pengelolaan keuangan daerah kota pekanbaru. Secara khusus, riset ini menguji pengaruh kualitas anggaran, penerapan sistem informasi pengelolaan keuangan daerah (SIPKD), dan pengawasan fungsional terhadap pengelolaan keuangan daerah. Selain itu, riset ini juga menguji peran komitmen pimpinan sebagai variabel moderating.Metode Penelitian: Riset ini adalah riset empirik menggunakan metode kuantitatif berbasis data primer. Sampel dipilih menggunakan metode purposive sampling dengan jumlah sampel 64 pegawai. Riset ini menggunakan pendekatan Partial Least Square-Structural Equation Modelling (PLS-SEM) dengan bantuan software WarpPLS dalam analisis data dan uji hipotesis.Hasil Penelitian: Hasil riset membuktikan bahwa kualitas anggaran, penerapan SIPKD, dan Pengawasan fungsional berpengaruh positif terhadap pengelolaan keuangan daerah. Selain itu, hasil riset ini menemukan bahwa komitmen pimpinan mampu memoderasi pengaruh penerapan SIPKD terhadap pengelolaan keuangan daerah.Keaslian/Kebaruan Penelitian: Ruang lingkup riset hanya dilakukan pada tiga organisasi perangkat daerah (OPD) Kota Pekanbaru sehingga generalisasi hasil riset masih rendah dan belum tentu bisa samakan dengan daerah lain. Riset ini menguji determinan atau faktor penentu optimalisasi pengelolaan keuangan daerah dengan memasukkan peran komitmen pimpinan sebagai variabel moderating.
Halo Effect : Corporate Social Responsibility (CSR) serta Peran Stakeholders Terhadap Kinerja Dan Nilai Perusahaan
Authors: Mawardi Fahmi Dwi
Published: July 2022

Latar Belakang: Tujuan utama perusahaan di era kerbelanjutan bisnis adalah meningkatkan kinerja dan nilai perusahaan melalui peran stakeholders. Hasil Penelitian Akisik (2017) masih terfokus pada perusahaan yang ada Eropa dengan konsensus pertanggungjawaban sosial yang tinggi, sedangkan di indonesia masih terkesan rendah karena kerbijakan yang semi mandatory. Peneliti bermaksud untuk meneliti di perusahaan indonesia dan menekankan juga pada aspek efek halo yang terjadi.Tujuan: Penelitian ini bertujuan untuk menganalisis secara empiris kelompok stakeholders utama yaitu karyawan dan pelanggan dalam mempertimbangkan ulasan pihak ketiga laporan CSR sebagai determinant value keputusan mereka, dan bagaimana keputusan mereka dapat mempengaruhi kinerja dan nilai perusahaan melalui halo efek laporan CSR.Metode Penelitian: Penelitian ini menggunakan moderated regression analysis (MRA) dengan e-views 10. Sampel yang digunakan adalah perusahan yang terdaftar di bursa efek Indonesia (BEI) dan Global Reporting Initiative (GRI).Hasil Penelitian: Hasil penelitian menunjukan dampak kelompok stakeholders karyawan dan pelanggan terhadap kinerja dan nilai perusahaan dipengaruhi oleh ulasan pihak ketiga laporan CSR. Penelitian ini menemukan adanya efek kuat dari stakeholder’s pelanggan yang ada di Indonesia terhadap peningkatan kinerja keuangan dan nilai perusahaan yang dipengaruhi oleh ulasan pihak ketiga CSR. Stakeholders pelanggan lebih memberikan apresiasi berupa dukungan pada perusahaan yang melakukan komitmen sosial dan lingkungan. Dukungan pelanggan berupa niat pembelian, penghargaan produk yang lebih tinggi dan stigma baik terhadap produk perusahaan. Penelitian ini menemukan adanya efek halo yang terjadi pada stakeholders karyawan. Karyawan merupakan stakeholders internal yang tidak bisa terlepas dari dinamika aktivitas perusahaan termasuk CSR. Aliansi stakeholders secara luas menemukan adanya ketidakrelevanan atas informasi dan aktivitas CSR yang dilakukan oleh perusahaan, sehingga menghasilkan keputusan untuk tidak mendukung perusahaan.Keaslian/Kebaruan Penelitian: Penelitian ini dibatasi oleh minimnya perusahaan di Indonesia yang menggunakan pedoman GRI. Penelitian ini memperluas penelitian Akisik (2019) dengan menggunakan variabel pemoderasi dan dilakukan pada perusahaan di Indonesia.
