Authors: Lasdi Lodovicus
Published: December 2020

Academics said that earnings management and conservatism literatures are two different topics. Conservative accounting is different from earnings management in earnings determination. However, other academics claim that it is difficult to differentiate earnings management from conservatism in accounting. Both concepts have the same idea that manager can use their judgement to influence financial reporting, that is discretionary accrual. The purpose of this article is bridging this two stream by looking interaction between earnings management and conservatism in accounting.

Is There A Fe(Male) Approach In Customer Relationship Management?
Authors: Herlambang Tedy
Published: December 2020

Customer relationship management (CRM) has been the favorite topic of scores of marketing consultants and academicians for over a decade. CRM approaches marketing as dating in which the marketer attempts to turn strangers into friends and friends into lifetime partners and to retain the loyalty of the right customers for this is the key to long-term profits in a company. Gender theories posit that women and men behave differently, and that they approach things differently. Moreover, these theories have documented a picture of women are being more expert and motivated relationship psychologists than men, as more active in their relationship monitoring, and as more oriented toward the maintenance and success of their relationships. Based on these theories, this paper develops some propositions to facilitate its empirical testing related to relationship communication and relationship dissolution in business market. The contribution of this paper is twofold. First, it attempts to create more insight into areas where relationship marketing research to date has not been abundant. Second, this paper attempts to contribute to methodological development of measuring relationship success by systematically distinguishing between good communication relationship and good management relationship.

Pengaruh Identitas Sosial Dan Co-Creation Terhadap Niat Berperilaku Anggota Komunitas Online VW: Efek Moderasi Nostalgia
Authors: Sukoco Badri Munir , Teko TP Untung
Published: December 2020

Developing relationships with customers through brand community is the recent tool for marketers for customer relationship management (CRM) program. The existence of a community, especially virtual, depends on the members’ participation as well as their recommendation to others. Previous studies indicate that members’ participation and recommendation depends on how deep is their identification toward the community. This article argues that social identification itself is not enough, unless the members engage in co-creation activities by exchanging knowledge with other members (co-consumption) and producers (co-production). Further, this article further argues that the effect of social identity on members’ co-creation and behavioral intentions will be moderated by their nostalgia proneness. We conducted survey among Volkswagen Indonesia CyberCommunity (VICC) members as one of the legendary brand in Indonesia. The results indicate that direct effect of social identity on members’ behavioral intentions is greater than indirect effect through co-creation. The moderating effect of nostalgia proneness is significant on the relationship between social identity and behavioral intentions, in which the effect is larger when members’ identification is low. Managerial and academic implications are further discussed in this paper.

Published: December 2020

In Differentiated Services (DiffServ) architecture, Priority Service System (PSS) plays a vital responsibility to provide Quality-of-Service (QoS) for the applications based on networks. Priority queuing systems has always been a subject of interest for analytical modelling and evaluating the performance. However, previous works have mainly focused on performing priority queuing under range dependent traffics, namely Short Range Dependent (SRD) or Long Range Dependent (LRD). Recent studies revealed that realistic traffic demonstrates a heterogeneous nature for the modern networks that provide multiple services. In this paper, the results of analytical and simulation models of dynamic priority service systems is reviewed to study the heterogeneous traffic impact on designing and performance of the systems based on networks. In this paper, the results of analytical and simulation models of dynamic priority service systems is reviewed to investigate the impact of heterogeneous traffic on the design and performance of network-based systems. Here, the time of presence of requests in limited and unlimited buffer system is restricted. If the restriction is violated, the requests will be lost. The results of experiments conducted on both models are compared and it is identified that they differ in the allowable limit (2-9) %.

Published: December 2020

There are limited proven therapies for the treatment of COVID-19. Vitamin C’s antioxidant, anti-inflammatory and immunomodulating effects, make it a potential therapeutic candidate, both for the prevention and amelioration of COVID-19 infection, and as an adjunctive therapy in the critical care of COVID-19, supporting anti-inflammatory treatment. This literature review focuses on vitamin C deficiency in respiratory infections including COVID-19; the mechanism of action in infectious disease and adrenal function supporting the anti-inflammatory actions of glucocorticosteroids: its role in preventing and treating colds and pneumonia and its role in treating sepsis and COVID-19. The evidence to date indicates that oral vitamin C (2-8g/d) may reduce incidence and duration of respiratory infections and intravenous vitamin C (2-24g/d) has been shown to reduce mortality, Intensive Care Unit and hospital stays, time on mechanical ventilation in severe respiratory infections. Further trials are urgently warranted. Given the favourable safety profile and low cost of vitamin C, and frequency of vitamin C deficiency in respiratory infections it may be worthwhile testing patients’ vitamin C status and treating accordingly with intravenous use within ICUs and orally with doses between 2 and 8g/day in hospitalised and infected persons.
Iterative Receiver Design for the Estimation of Gaussian Samples in Impulsive Noise
Authors: Mirbadin Anoush , Vannucci Armando , Colavolpe Giulio , Pecori Riccardo , Veltri Luca
Published: December 2020

Impulsive noise is the main limiting factor for transmission over channels affected by electromagnetic interference. We study the estimation of (correlated) Gaussian signals in an impulsive noise scenarios. In this work, we analyze some of the existing as well as some novel estimation algorithms. Their performance is compared, for the first time, for different channel conditions, including the Markov-Middleton scenario, where the impulsive noise switches between different noise states. Following a modern approach in digital communications, the receiver design is based on a factor graph model and implements a message passing algorithm. The correlation among signal samples as well as among noise states brings about a loopy factor graph, where an iterative message passing scheme should be employed. As it is well known, approximate variational inference techniques are necessary in these cases. We propose and analyze different algorithms and provide a complete performance comparison among them, showing that both Expectation Propagation, Transparent Propagation, and the Parallel Iterative Schedule approaches reach a performance close to the optimal, at different channel conditions.

Authors: Crisci Alessandro , D'Adamo Raffaele , Crisci Michela
Published: December 2020

The supposition is that the usage of fibrin rich in leukocytes and platelets advanced (A-PRF) in ulcerative osteomyelitis of the diabetic foot allows rehabilitation from this critical illness. In this investigation, the focus was to normalize the use of PRF in patients with osteomyelitis not amputated, to use this second generation platelet concentrate as a regeneration enabler. The researchers submitted and utilized A-PRF membranes (1300 g × 8 min) in 7 patients (all diabetics) with osteomyelitis and cutaneous injury for 6 months. The membranes, in combination with the supernatant fluid produced by stress, have been integrated into the skin lesion down to the bone after surgical debridement. The advancement of the lesions after some period of time has been analyzed. All seven subjects had a Probe-to-Bone positive assay; MRI indicated a cortico-periosteal coagulation and/or foci of cortico-spongeous osteolysis contiguous to the lesion. Gram-positive bacterium were identified in our procedures in 52% of cases. Gram+ Cocci, for example, S. Aureus (15.6%), S. Hemolytic (12.1%), S. Viridans (7.1%), and Gram-negative Bacteria, for example, Pseudomonas (10.6%), Proteus (7.8%), Enterobacter (5.7%) are present. Candida Albicans is active in 2.8%. The blood count shows no relevant differences. To date, cutaneous lesions have cured in 6 of the seven subjects treated (one patient for more than five years) without any evidence of infection or recurrence. The results obtained on our subjects indicate that PRF membranes may be a therapeutic option in this problematic disease.
Agroclimatic Impact on Gastrointestinal Infection: A Mathematical Model
Authors: Ghosh Goutam , Bandyopadhyay Subhasish , Chattopadhyay Amit
Published: December 2020

Identifying the correct dosage and time are key factors to successful implementation of anthelmintic. Comparing differential evolution of infection between anthelmintic treated animals against untreated ones, we present a mathematical model that first calibrates data collected and analyzed over an extended period of 10 years (2011-2019), and then predicts the dynamical evolution of gastrointestinal parasites in livestock, focusing specifically on Stronglye \& Coccidia oocysts, the two prime negative contributors to cattle health, measured using the standard Eggs-Per-Gram (EPG) index. The model incorporates information about all three critical regimes of infection - low infection regime ($< 50$ EPG), medium infection regime ($50-100$ EPG) and high infection regime ($>100$ EPG), including fatally large doses of infection ($> 500$), and probabilistically estimates the variation in animal weight due to infection propagation. A key success of our model is its ability to accurately predict the appropriate anthelmintic treatment times for cattle from a numerical solution of the model presented. The generic model can be applied to other agroclimatic conditions and can serve as a major diagnostic tool for anthelmintic strategizing.
Deep Ensemble of Weighted Viterbi Decoders for Tail-Biting Convolutional Codes
Authors: Raviv Tomer , Schwartz Asaf , Be'ery Yair
Published: December 2020

Tail-biting convolutional codes extend the classical zero-termination convolutional codes: Both encoding schemes force the equality of start and end states, but under the tail-biting each state is a valid termination. This paper proposes a machine-learning approach to improve the state-of-the-art decoding of tail-biting codes, focusing on the widely employed short length regime as in the LTE standard. This standard also includes a CRC code. First, we parameterize the circular Viterbi algorithm, a baseline decoder that exploits the circular nature of the underlying trellis. An ensemble combines multiple such weighted decoders, each decoder specializes in decoding words from a specific region of the channel words' distribution. A region corresponds to a subset of termination states; the ensemble covers the entire states space. A non-learnable gating satisfies two goals: it filters easily decoded words and mitigates the overhead of executing multiple weighted decoders. The CRC criterion is employed to choose only a subset of experts for decoding purpose. Our method achieves FER improvement of up to 0.75dB over the CVA in the waterfall region for multiple code lengths, adding negligible computational complexity compared to the circular Viterbi algorithm in high SNRs.
An Effective Heart Disease Prediction Model based on Machine Learning Techniques

Published: December 2020

This paper presents an effective heart disease prediction model through detecting the anomalies, also known as outliers, in healthcare data using the unsupervised K-means clustering algorithm. Most existing approaches for detecting anomalies are based on constructing profiles of normal instances. However, such techniques require an adequate number of normal profiles to justify those models. Our proposed model first evaluates an \textit{optimal} value of K using Silhouette method. Next, it intends to locate anomalies that are far from a certain threshold distance with respect to their clusters. Finally, the five most popular classification techniques such as K-Nearest Neighbor (KNN), Random Forest (RF), Support Vector Machines (SVM), Naive Bayes (NB), and Logistic Regression (LR) are applied to build the resultant prediction model. The effectiveness of the proposed methodology is justified using a benchmark dataset of heart disease.
Adjuvant Pancreatic Cancer Management: Towards New Perspectives in 2021
Authors: Turpin Anthony , el Amrani Mehdi , Bachet Jean-Baptiste , Pietrasz Daniel , Schwarz Lilian , Hammel Pascal
Published: December 2020

Adjuvant chemotherapy is currently used in all patients with resected pancreatic cancer who are able to begin treatment within 3 months after surgery. Since the recent publication of the PRODIGE 24 trial results, modified FOLFIRINOX has become the standard-of-care in the non-Asian population with localized pancreatic adenocarcinoma following surgery. Nevertheless, there is still a risk of toxicity, and feasibility may be limited in heavily pre-treated patients. In more frail patients, gemcitabine-based chemotherapy remains a suitable option, for example gemcitabine or 5FU in monotherapy. In Asia, although S1-based chemotherapy is the standard of care it is not readily available outside Asia and data are lacking in non-Asiatic patients. In patients in whom resection is not initially possible, intensified schemes such as FOLFIRINOX or Gemcitabine-Nabpaclitaxel have been confirmed as options to enhance the response rate and resectability, promoting research in adjuvant therapy. In particular, should oncologists prescribe adjuvant treatment after a long sequence of chemotherapy +/- chemoradiotherapy and surgery? Should oncologists consider the response rate, the R0 resection rate alone, or the initial chemotherapy regimen? And finally, should they take into consideration the duration of the entire sequence, or the presence of limited toxicities of induction treatment? The aim of this review is to summarize adjuvant management of resected pancreatic cancer and to raise current and future concerns, especially the need for biomarkers and the best holistic care for patients.

Published: December 2020

To understand the physiological basis of tolerance to combined stresses to low phosphorus (P) and drought in mungbean (Vigna radiata (L.) R. Wilczek), a core set of 100 accessions were evaluated in hydroponics at sufficient (250 μM) and low (3 μM) P, and exposed to drought (dehydration) stress. The principal component analysis and ranking of accessions based on relative values revealed that IC280489, EC397142, IC76415, IC333090, IC507340 and IC121316 performed superior while IC119005, IC73401, IC488526 and IC325853 performed poorly in all treatments. Selected accessions were evaluated in soil under control (sufficient P, irrigated), low P (without P, irrigated), drought (sufficient P, withholding irrigation) and combined stress (low P, withholding irrigation). Under combined stress, a significant reduction in gas exchange traits (photosynthesis, stomatal conductance, transpiration, instantaneous water use efficiency), P uptake in seed and shoot was observed under combined stress as compared to individual stresses. Among accessions, IC488526 was most sensitive while IC333090 and IC507340 exhibited tolerance to individual or combined stress. The water balance and low P adaptation traits like membrane stability index, relative water content, specific leaf weight, organic acid exudation, biomass, grain yield and P uptake can be used as physiological markers to evaluate for agronomic performance. Accessions with considerable resilience to low P and drought stress can be either used as ‘donors’ in Vigna breeding program or cultivated in areas with limited P and water availability or both.
Non-Homologous end Joining Factors XLF, PAXX and DNA-PKcs are Required to Maintain the Neural Stem and Progenitor Cell Population
Authors: Gago-Fuentes Raquel , Oksenych Valentyn
Published: December 2020

Non-homologous end-joining (NHEJ) is a major DNA repair pathway in mammalian cells that recognizes, processes and fixes DNA damages throughout the cell cycle, and is specifically important for homeostasis of post-mitotic neurons and developing lymphocytes. Neuronal apoptosis increases in the mice lacking core NHEJ factors Ku70 and Ku80. Inactivation of other core NHEJ genes, either Xrcc4 or Lig4, leads to massive neuronal apoptosis in the central nervous system (CNS) that correlates with embryonic lethality in mice. Inactivation of one accessory NHEJ gene, e.g. Paxx, Mri and Dna-pkcs, results in normal CNS development due to compensatory effects of Xlf. Combined inactivation of Xlf/Paxx, Xlf/Mri and Xlf/Dna-pkcs, however, results in late embryonic lethality and high levels of apoptosis in CNS. To determine the impact of accessory NHEJ on early stages of neurodevelopment, we isolated neural stem and progenitors cells from mouse embryos and investigated proliferation, self-renewal and differentiation capacity of these cells lacking either Xlf, Paxx, Dna-pkcs, Xlf/Paxx or Xlf/Dna-pkcs. We found that accessory NHEJ factors are important for maintaining the neural stem and progenitor cell populations and neurodevelopment in mammals, which is particularly evident in the double knockout models.
Musicians’ Earplugs: Do They Affect Performance or Listeners’ Perceptions?
Authors: Thomas Karen S. , Smith Raychl , Teglas Sandra , Hodges Donald A.
Published: December 2020

BACKGROUND: Does wearing musicians’ earplugs while performing affect the quality of the performance? Can listeners perceive a difference in sound when musicians are performing with or without earplugs? The risk of hearing loss is a concern for musicians, but some are reluctant
to wear hearing protection due to factors such as an inability to hear their own instrument properly and the possibility of decreased sound quality for listeners. OBJECTIVE: The purpose of this study was to determine the effect of musicians’ earplugs on instrumental pitch accuracy and
the perception of tone quality, intonation, and dynamic contrast, as perceived by musicians and listeners. METHODS: Ten university studio faculty teachers were recorded performing single pitches and lyrical and technical passages, first without earplugs and then immediately after with earplugs.
A sample of 8 studio faculty teachers and 88 undergraduate music education students completed a researcher-created music perception test of tone quality, intonation, and dynamic contrast. RESULTS: Objective analyses of the single pitch recordings made by faculty with and without earplugs indicate
that pitch accuracy did not favor either condition consistently. Results from the perception test indicate that although both faculty and student listeners perceived some differences, the most frequent perception was that the audio pair was equal, and there was no clear difference between
performing with and without earplugs in terms of tone quality, intonation, or dynamic contrast. CONCLUSION: These findings suggest that musicians should feel confident that wearing musicians’ earplugs while performing does not adversely affect pitch accuracy or listeners’ perceptions

OBJECTIVE: To gain insight into the prevalence and characteristics of physical health problems and mental health problems in first-, second- and third-year conservatoire students of the classical music department. Also, differences in mental health and general health were investigated
between students with playing-related musculoskeletal disorders (PRMDs) and students without PRMDs. METHODS: Eighty-nine classical music students of Codarts Rotterdam, University of the Arts, were asked to complete a questionnaire targeting PRMDs (components derived from Musculoskeletal Pain
Intensity and Interference Questionnaire for Musicians, MPIIQM), mental health (Mental Health Inventory-5), and self-rated general health (SF-1 from Short Form health survey SF-12). RESULTS: The response rate was 52% (n=46). Of all participants, 17.8% (n=8) had experienced PRMDs in the past
12 months and 45.7% (n=21) of the students reported poor mental health (MHI-5≤60). Students experiencing PRMDs in the past 12 months reported poorer general health compared to students without PRMDs (43.8 vs 67.1 [range 0–100], p=0.012). No significant difference was found between
the groups with regard to mental health (62.0 vs 66.5 [range 0–100], p=0.522). CONCLUSION: The burden of PRMD complaints in this population of conservatoire students seems relatively low. However, the number of students facing mental problems in this population is a cause for concern.
Conservatoires should focus on the subject of mental health in their curricula to increase more awareness and prevent mental problems. To investigate possible causality between PRMDs and general health, prospective studies are needed.

Sentimen adalah proses komputasional dalam mengidentifikasi dan mengategori opini-opini dalam bentuk potongan teks, khususnya untuk mengukur maksud si pembuat potongan teks terhadap topik tertentu, dapat bernada positif, negatif, atau netral. Dalam konteks layanan perusahaan, sentimen yang sering muncul biasanya adalah sentiment yang bernilai positif dalam bentuk pujian dan apresiasi maupun sentiment bernilai negatif dalam bentuk complain. Ketika komplain dilakukan oleh pelanggan, maka pihak perusahaan harus dapat melakukan tindakan untuk menanggulangi komplain tersebut, yang dimungkinkan dapat berimbas terhadap kredibilitas perusahaan, bahkan dapat berimbas pada harga saham. Sosial media menjadi tempat yang dapat digunakan untuk menyampaikan keluhan maupun review positif dari pelanggan terhadap layanan yang diberikan oleh perusahaan. Proses analisis sentimen pelanggan terhadap layanan perusahaan perlu dilakukan untuk mengetahui seberapa besar jumlah sentimen yang muncul menggunakan metode KNN dengan studi kasus pada perusahaan telekomunikasi di Indonesia. Kemudian dilakukan analisis regresi untuk menilai apakah jumlah sentimen pelanggan berpengaruh terhadap harga saham perusahaan. Penelitian ini menghasilkan sentimen positif sebesar 16% , sentimen negatif sebesar 78 % dan sentimen netral sebesar 6%. Metode KNN menghasilkan akurasi paling tinggi sebesar 79,06% pada cross validation = 4. Jumlah sentimen negatif dan harga saham memiliki nilai regresi dan nilai korelasi sebesar 0,46 atau dengan kata lain tidak memiliki keterikatan satu sama lain. Sentimen positif menghasilkan nilai regresi dan korelasi sebesar 0,02 dengan artian memiliki keterikatan satu sama lain.

In pandemic era, almost everyone struggles for their life. College students are such example. They have difficulty in paying tuition fee to continue their study. Based on this problematic situation, Universitas Teknokrat Indonesia grants the students who have good academic performance with tuition fee aid program. Many variables used for determining the grant made it hard to make a decision in a short time or even takes very long time. To make it easier for management to decide who is the right student to get grant, it needs classification model. The purpose of this study is the classification of grant recipients by using decision tree C4.5 algorithm. That can determine whether a potential student can be accepted as an awardee or not. Then, the results of the classification are validated with ten-fold cross validation with an accuracy, precision and recall with the score of 87 % for all part. It means the model perform quite well to be implemented into system.

The present work involves studying the effect of electrolyte composition [@1= 0.5 wt.%  NH4F / 5% H2O / 5% Glycerol (GLY)/ 90%  Ethylene Glycol (EG)] and [ @2= 0.5 wt. % NH4F / 5% H2O / 95%  Ethylene Glycol (EG)]  on the structural and photoelectrochemical properties of titania nanotubes arrays (TNTAs). TNTAs substrates were successfully carried out via anodization technique and were carried out in 40 V for one hour in different electrolytes (@1, and @2). The properties of physicochemical of TNTAs were distinguished via an X-ray Diffractometer (XRD), Field Emission Scanning Electron Microscope (FESEM), an Energy Dispersive X-ray (EDX), and UV–visible diffuse reflectance. The photoelectrochemical response of TNTAs was evaluated in 0.01M Na2S under the choppy light of a halogen lamp. TNTAs photoelectrode prepared at @1 electrolyte was not sufficient to increase the photocurrent response compared to TNTAs prepared at @2. The TNTAs photoelectrode prepared in the @2 electrolyte confirmed the highest photoconversion efficiency compared to the TNTAs photoelectrode prepared in the @1 electrolyte.
