AUTHENTIC ASSESSMENT E-LEARNING PROGRAM IN LEARNING WRITING SCIENTIFIC WORKS
Authors: Zenab Ai Siti , Rostikawati Yeni 
Published: July 2023

Electronic learning system or better known as e-learning (electronic learning) is a learning program designed using web-based computer networks and the internet. The use of this system in Indonesian tertiary institutions continues to grow annually. One reason this system continues to evolve is that it is considered effective for distance learning and can help a wider area with more students. Besides, the system causes students and teachers not to use a protocol system that shows its rigid nature. Lectures run more flexibly by sticking to the final results already listed in the curriculum. To measure the level of success of a learning process evaluation is needed. One type of evaluation that can be used is authentic assessment. This assessment involves all the processes carried out in each lecture activity starting from the process, attitude, results. The research method used is descriptive qualitative. The results obtained were 86.21% of students actively involved in the lecturing process. For assignment grades, 31.03% of students received an Excellent grade (SB), 65.52% received a good grade (B). For the UTS score, the highest value obtained in the Good criteria (B) is 52.72%. The rest are in the Fair (C) and less (K) criteria. For UAS, the highest score depends on the Good criteria (B) 65.52%, while the rest depends on sufficient criteria and requires improvement. From the results of these data, it is evident that e-learning lectures require additional evaluations for each meeting, periodic checks, and fast responses to complaints expressed by students both related to teaching materials and those related to the system.Â Keywords: Authentic Assessment, Writing Scientific Papers, E-LearningÂ Â

Reputation Repair after a Restatement: The Role of Corporate Social Responsibility Disclosure
Authors: Dong Lei , Wang Y. Ken 
Published: July 2023

ABSTRACT
Issuing restatements undermines market value and management reputation. Using an experiment, this study examines whether corporate social responsibility (CSR) disclosure can repair the damaged reputation following a restatement. Two aspects of CSR information are considered—presence of CSR disclosure and source of CSR disclosure. The results show that disclosing positive CSR activities is an effective way to repair management reputation and enhance investment interest. Also, there is an incremental benefit if investors receive CSR information from an independent source. This study contributes to the limited literature on the effectiveness of corrective actions after a restatement by demonstrating that individual investors’ judgments and decisions after a prominent trust-damaging event, i.e., financial restatement, are affected by both the presence and the source of CSR information. This study contributes to the literature by providing direct, experimental evidence in accounting on CSR disclosure as a reputation-restoring mechanism after a restatement.

An Investigation of Misreporting Choice, Team Membership, and Task Similarity on Whistleblowing Decisions
Authors: Ong Alyssa S. J. , Geng Xin 
Published: July 2023

ABSTRACT
Individuals in their roles at work may have the opportunity to commit fraud. They may also be in a position to witness the occurrence of fraud in the workplace. In this study, we examine how individuals' prior decision to commit fraud influences their subsequent decision to whistleblow on another person when (1) the person is in the same team as them or (2) the other person is committing fraud on the same/different task as they did. With two between-subject experiments, we find that individuals who decided to commit fraud are less likely to whistleblow on another fraudster than individuals who decided not to commit fraud. We also find that individuals are more likely to whistleblow on other fraudsters who belong to the same team (task) as them than on fraudsters on a different team (task). The results suggest that heightened team identification can be a powerful means to accentuate whistleblowing.

Authors: Deng J , Jin C , Zhu L , Liu L , Huang Y , Zhao P , Gao S 
Published: July 2023

SUMMARY

Purpose
To determine the effects of various primers on the immediate and long-term bond strength of ceramic-coated ultratranslucent zirconia that is properly or excessively etched.

Methods and Materials
Ceramic-coated zirconia plates were etched with 9.5% hydrofluoric acid (HF) for 2 or 5 minutes, after which the surface morphology and elemental composition were examined. The etched specimens were treated with different primers including methacryloyloxydecyl dihydrogen phosphate (MDP)-only containing primer, silane-only containing primer, MDP and silane-containing ceramic primer as well as MDP and silane-containing adhesive system. For surface contact angle and shear bond strength (SBS) data, the difference between groups was evaluated by one-way analysis of variance (ANOVA) and three-way ANOVA factorial analysis, respectively. The statistical significance level of 0.05 was set and the Tukey test and the Dunnett-T3 test were used for post-hoc multiple comparisons.

Results
Excessive etching (9.5% HF for 5 minutes) led to overconsumption of the glass layer and exposure of zirconia substrate compared to proper etching (9.5% HF for 2 minutes). Among different primers, the surface contact angle of the silane-only containing primer group was the lowest. The silane-only containing primer and MDP and silane-containing ceramic primer produced higher shear bond strength of properly and excessively etched ceramic-coated zirconia, respectively, both before and after thermal aging.

Conclusions
The silane-only containing primer and MDP and silane-containing primer can obtain better immediate and long-term shear bond strength for properly and excessively etched ceramic-coated zirconia, respectively.
A Review on Brucellosis in Tanzania: Prevalence in Livestock, Wildlife, and Humans from 1962-2021, Public Awareness and Knowledge on the Disease, and the Way Forward towards Disease Control
Authors: Masola Seleman , Bakengesa Innocent , Chang'a Edwin , Guni Fadhili 
Published: July 2023

Brucellosis is a zoonotic disease which is among the most widespread and neglected diseases in the world. Most affected parts of the world include the Mediterranean countries of Europe, North and East Africa, the Middle East, South and Central Asia as well as Central and South America. This paper reviews the prevalence of brucellosis in Tanzania as well as public awareness and knowledge on the disease in the past six decades, from 1962 to 2021. Literatures were searched using Google Scholar database. The criteria for literature inclusion or exclusion were the type of literature, year of publication and the country where the study was conducted. In livestock, the disease prevalence ranged from 2.16 to 48% in cattle, 0.2 to 13.79% in goats and 0 to 23% in sheep. A prevalence of 0.7% was reported in pigs. In humans, the prevalence ranged from 0 to 48.4%. The prevalence of brucellosis in wildlife was 0% in baboon, 25% in hyena, 30% in impala, 36.8% in lions, 4% in zebra, ranged from 7.9 to 24% in African buffalo and 3.8 to 17% in wildebeest. Generally, the public awareness and knowledge on the disease were low due to the lack of a well- established channel for sharing of research findings which is friendly to all stakeholders. In the past six decades more emphasis was on research which led to generation of data presented in this review. Although education campaigns to raise public awareness and knowledge on the disease transmission, its control, and socio-economic effects were recommended in many reports, no significant work was done during the period under review. In order to control and prevent brucellosis in the country, embarking on education campaigns to raise public awareness and knowledge on the disease is a recommended way forward, followed by implementation of other objectives outlined in the National Strategy for Prevention and Control of Brucellosis in Humans and Animals.
