Investors' Interpretations of Imprecise Standards and Their Perceptions of Earnings Management by Reputable Companies
Authors: Tan Hwee-Cheng , Mayorga Diane
Published: January 2020

Standards with imprecise guidelines require interpretation by users. In this study we investigate how investors' perceptions of earnings management vary with their interpretations of imprecise standards and the type of company reputation. We design a quasi-experiment that exploits the role of the press as a “watchdog” of corporate activities to focus the attention of investors on the financial reporting practices of companies. The results show that both factors interact to influence investors' perceptions. Investors, whose interpretations of the imprecise standard are inconsistent with that of the company, are more likely to suspect earnings management when the company has a financial rather than non-financial reputation. Investors in the inconsistent/financial reputation condition are also more likely to sell their investments than those in the inconsistent/non-financial reputation condition. The type of reputation does not show a significant effect on investors' perceptions when investors' interpretations are consistent with that of the company.

Learning from Ethical Violations in Public Accounting: A South African Audit Scandal and a Firm's Transformation
Authors: Holtzblatt Mark A. , Foltin Craig , Tschakert Norbert
Published: January 2020

This case provides students with an opportunity to examine ethical issues and challenges encountered in public accounting. This real-life case occurred in South Africa, where wide-spread corruption and unethical behavior severely affected a global accounting firm. Due to the resulting negative publicity, the firm suffered significant reputational damage and underwent investigations by the audit regulator and professional accounting society. Consequently, the firm initiated major transformations of management, governance, and audit quality procedures. Students are required to research and analyze issues involving the accounting firm's South African activities. However, the matters addressed are universal and encountered by firms globally. The case learning objectives include improving understanding of the value of auditor independence, the importance of ethical behavior to a global firm's reputation, ways to promote ethical conduct, and how professional skepticism can identify ethical misconduct. The case is designed for auditing, forensic accounting, international accounting, accounting policy, and ethics courses.
Semantic Processing Theory Could Help Explain the Effectiveness of Creativity Incentives: A Numerical Experiment
Authors: Knox Brian D.
Published: January 2020

Two seminal accounting studies find that output creativity is insensitive to creative effort: workers simplify creativity-weighted contracts by focusing on increasing creativity, but they cannot increase output creativity enough to compensate for sacrifices they make to output quantity. Other studies, however, find evidence that output creativity is sensitive to creative effort. To examine these differing results, I use a numerical experiment: I model workers in quantity contracts and creativity-weighted contracts, and I proxy creative effort as workers' choice between fine semantic processing (less creative) and coarse semantic processing (more creative). My numerical experiment's results show (1) output creativity's sensitivity to creative effort when the task is less inherently creative and (2) output creativity's insensitivity to creative effort when the task is more inherently creative. More inherently creative tasks effectively require coarse semantic processing in both contracts, limiting workers' ability to give incrementally more creative effort in response to creativity incentives.

Published: January 2020

OBJECTIVE

Dual incretin receptor agonists in clinical development have shown reductions in body weight and hemoglobin A1c (HbA1c) in patients with type 2 diabetes, but the impact of glucose-dependent insulinotropic polypeptide (GIP) receptor activation remains unclear. Here, we evaluated the effects of high-dose exogenous GIP on energy intake, energy expenditure, plasma glucose, and glucose-regulating hormones in patients with type 2 diabetes treated with a long-acting glucagon-like peptide 1 receptor (GLP-1R) agonist.

RESEARCH DESIGN AND METHODS

In a randomized, double-blind design, men with type 2 diabetes (n = 22, mean ± SEM HbA1c 6.8 ± 0.1% [51 ± 1.5 mmol/mol]) treated with metformin and long-acting GLP-1R agonists were subjected to two 5-h continuous infusions (separated by a washout period of ≥3 days): one with GIP (6 pmol/kg/min) and another with saline (placebo). After 60 min of infusion, a liquid mixed-meal test was performed, and after 270 min of infusion, an ad libitum meal was served for evaluation of energy intake (primary end point).

RESULTS

Energy intake was similar during GIP and placebo infusion (648 ± 74 kcal vs. 594 ± 55 kcal, respectively; P = 0.480), as were appetite measures and energy expenditure. Plasma glucagon and glucose were higher during GIP infusion compared with placebo infusion (P = 0.026 and P = 0.017) as assessed by area under the curve.

CONCLUSIONS

In patients with type 2 diabetes, GIP infusion on top of treatment with metformin and a long-acting GLP-1R agonist did not affect energy intake, appetite, or energy expenditure but increased plasma glucose compared with placebo. These results indicate no acute beneficial effects of combining GIP and GLP-1.
Deep penetration laser welding of austenitic stainless steel thick-plates using a 20 kW fiber laser
Authors: Fang Chao , Xin Jijun , Dai Wenhua , Wei Jing , Wu Jiefeng , Song Yuntao
Published: January 2020

The deep penetration laser welding of a thick section of austenitic stainless steel by a 20 kW laser is systematically evaluated. The welding phenomena of bead-on-plate and butt-welding of 20 and 30 mm thick steel plates are examined. The results show that the penetration depth of bead-on-plate welding can reach 32 mm and that wide processing windows exist to obtain defect-free butt-welding of 20 mm thick plates, but not for 30 mm thick plates. When the welding position is changed from a flat welding position (1G) to a horizontal welding position (2G), butt-welding of 30 mm thick plates can be penetrated successfully to obtain defect-free welds. The weld joint maintains the full austenite microstructure, which is composed of mostly directional columnar and cellular grains, while there are some equiaxed grains at the weld center.
Laser-induced thermal emission of rough carbon surfaces
Authors: Karpovych Valeria , Tkach Olga , Zelenska Kateryna , Zelensky Serge , Aoki Toru
Published: January 2020

The decay of thermal emission of rough surface layers of different carbon materials under the pulsed laser excitation is analyzed both theoretically and experimentally. For pulsed laser heating of rough surfaces, computer simulations revealed that laser-induced thermal radiation is mainly emitted by peaks of the surface relief, and the emission decay time depends on the relation between the laser penetration depth and the temperature diffusion length. It is also concluded that the presence of surface roughness can significantly increase the emission decay time. In the experiments, carbon materials with different thermal characteristics were used; however, all of the investigated samples demonstrated close values of the emission decay time. This fact shows that the material's characteristics on the peaks of surface relief are similar for different carbon materials at high temperature.

Published: January 2020

THE AIM OF THE STUDY. was an index creation for both single and multiple acute traumatic intracranial hematomas (ATIH) for objectification of the surgical treatment indications and using multispiral computed tomography (MSCT) and based on up-to-date clinical recommendations.

MATERIAL AND METHODS. We performed a retrospective study of 3 groups of patients with ATIH. Group 1 included 19 patients who were treated conservatively and discharged from the hospital without complications (group of conservative treatment). Group 2 included 9 patients who were observed after hospitalization and were treated in a delayed manner surgically due to growth of the intracranial hematoma volume or the patient condition deterioration (group of observation). Group 3 included 18 patients who were operated due urgent indications (group of surgical treatment). For each patient, the acute traumatic hematoma index (ATHI) was calculated by our original formula. It took the ATIH location, volume in milliliters according to the first MSCT, and risk factors significant for poor outcomes into account. After a preliminary assessment of the significance of differences between the studied characters of groups, a discriminant analysis was carried out with determination of the ATHI values in each group.

RESULTS AND CONCLUSIONS. The suggested ATHI index has been shown to be effective in assessing single and multiple ATIHs of any location in accordance with current recommendations. The index is an objective (digital) and easy-to-use for determining ATIH surgical treatment indications and statistical treatment. If ATHI is less than 3 points, there are no indications for surgery and the repeated MSCT of the brain is indicated at least 12 hours after the first checkup or if the suspicious clinical sings appear; if ATHI is 3–4, the indications for surgery are relative and the repeated MSCT of the brain is required 6 hours later even if the patient condition is unaltered; the surgery is indicated if ATHI is more than 4 points.

Ultrasound determined the type and extent of destruction of lung tissue by signs of infiltration and consolidation.

RESULTS. In the studied patients, after carrying out a maneuver of recruitment of the alveoli, arterial blood oxygenation indices increased statistically significantly, PaCO2 level decreased, pulmonary tissue compliance improved, respiratory volume grew. All this confirmed the mobilization of the alveoli and improved lung ventilation. Ultrasonographic evaluation of lung tissue showed a significant decrease in the severity of the ultrasound sign of infiltration after recruitment maneuver from 46.5 (38; 57.5) to 37.5 (30.5; 49.5). However, recruitment had practically no effect on the volume of the consolidated area of lung tissue: the general consolidation index before (4 (3; 5)) and after (4 (3; 5)) the maneuver had no statistically significant differences.

CONCLUSIONS. The pneumonia-affected consolidated lung tissue has a low recruitment potential and the volume of consolidation does not change with the growth of PEEP. After the recruitment maneuver, the number of B-lines decreases, indicating a decrease in infiltration and an increase in lung airness.

Introduction: The interactive teaching system is one such tool which aims at improving the conventional lecture. In this study we had compared three types of interactive teaching viz., flipped class room, MCQ (Multiple Choice Question) based interactive teaching and confusion technique by kircpatrics level 1 evaluation. Methodology: It was an academic study conducted for a period of 1year for final year M.B.B.S students’ batch of 50 in Obstetrics and Gynaecology department of NEIGRIHMS from March 2018 to March 2019. Out of a total of 12 topics selected for interactive teaching technique, 4 topics were taught in flipped classroom technique, another 4 taught with putting MCQ in the class and remaining 4 topics were taught using confusion technique. Immediate feedback was obtained from students using likert chart. All the data were collected and analysed by Wilcoxon Signed rank test by using SPS Software 22. Observation: Flipped classroom technique of teaching was found preferable to MCQ technique (p value<0.01). Also flipped class room technique was preferred by student to confusion technique (p value<0.01). On comparision between MCQ and Confusion technique, MCQ was preferred by the students (p value <0.01). Conclusion: Interactive techniques and strategies make the students actively involved in the learning process, retaining more information and hence leaving them satisfied. In our study, flipped classroom method was the most preferred method by the students as a modality of interactive teaching when compared to MCQ based teaching and Confusion technique.

Abstrak:  

Keterbukaan akses informasi di era digital memberikan peluang bagi partai politik melalui struktur berjenjang untuk membangun komunikasi politik, berkaitan dengan usaha pencapaian kehidupan demikratis dan peningkatan derajat kualitas kepercayaan masyarakat kepada parpol sebagai salah satu wadah konstitusional. Melalui komunikasi isu dan gagasan politik, parpol berupaya memperoleh sejumlah akumulasi pendapat individual secara terbuka dan membentuk opini publik melalui suatu kegiatan berupa debat pembicaraan, atau pertukaran informasi antara individu yang berada dalam satu kelompok. Dampak komunikasi politik dan opini publik terhadap perilaku masyarakat tidak dapat digeneralisir, karena dampak berbeda yang ditimbulkannya pada setiap individu karena perbedaan latar belakang usia, jenis kelamin, agama, pendidikan, kecerdasan, pekerjaan, kelas sosial-ekonomi, dan sebagainya. Selain itu, publik adalah manusia yang bisa menerima, menolak, mempertanyakan, mengkritisi sehingga dengan begitu banyaknya sumber informasi, publik bisa membandingkan pesan dari satu media dengan pesan dari media yang lain, atau dengan pesan dari public figure atau otoritas yang ia percayai.

El modelo legal de conciliación y mediación en Brasil
Authors: Esis Ivette
Published: January 2020

Frente a la denominada “cultura de la sentencia” arraigada en la sociedad brasilera, las autoridades del Poder Ejecutivo y del Poder Legislativo han emprendido un importante esfuerzo en pro de brindar acceso al ciudadano a los mecanismos autocompositivos de solución de controversias, tanto en forma presencial como en forma digital. Las últimas reformas legislativas permiten a la Administración pública crear cámaras especializadas para prevenir y resolver conflictos por vía de la mediación, como también habilitan notarías y registros para ofrecer servicios de mediación a la colectividad. A pesar del esfuerzo realizado y de las iniciativas implementadas, aún falta mucho para lograr disminuir el nivel de litigiosidad por lo que se hace necesario reforzar y socializar en la ciudadanía la importancia de estos mecanismos.

Authors: Hernández Muñoz Alejandra
Published: January 2020

A partir de informações on line e pesquisa in loco, o texto apresenta uma reflexão sobre dois grupos de ações e trabalhos que configuram dois formatos de discussão e produção da arte contemporânea: a Manifesta (evento bianual itinerante realizado na Europa desde 1996) e o Vila Sul (programa de residências do Goethe-Institut Salvador-Bahia). Nos dois casos, realizamos uma breve contextualização das modalidades de exposição temporária e de residências artísticas, respectivamente. Na sequência, a modo de diagnóstico, examinamos as contribuições de cada edição da Manifesta na configuração de uma plataforma de debate, produção e promoção artística, e um balanço dos três primeiros anos de atividades do programa Vila Sul e suas consequências. Finalmente apontamos perspectivas para as próximas edições anunciadas da Manifesta em 2020 e 2022 e do Vila Sul para 2020, ressaltando-se a relevância das práticas colaborativas e os desdobramentos dos intercâmbios internacionais na atualidade.

Goce en las infancias: hacia una genealogía del niño y niña de hoy
Authors: Lawrence Tomás
Published: January 2020

La presente investigación intenta repensaral niño y niña dentro del contexto de diversas transformaciones socio-culturales de nuestra época. La caída de referentes culturales, los cambios gubernamentales que han dado paso a nuevas legislaciones en torno al Derecho infantil, junto con una doctrina de las pantallas y las redes sociales, nos muestran una modificación de la percepción y construcción de la subjetividad infantil. El texto concluye con la idea de que surgen paradojas respecto a la infancia, la más significativa parece ser que mientras más énfasis se le pone a los Derechos de los niños y niñas simultáneamente, surge como subtexto un discurso anverso dando paso a un pseudo-empoderamiento de los niños, un excesivo goce en los menores de edad.

Importance of the Sacrament of Baptism for the Contemporary World
Authors: Boldisor Adrian George
Published: January 2020

Baptism has been a focus of significant discussion in the ecumenical movement, as the different churches seek a common understanding of Baptism, with the goal of mutual recognition. The Orthodox Church has been involved in these conversations from the beginning. The present article is an attempt to trace the participation of the Orthodox representatives in these dialogues on Baptism, both at the level of the World Council of Churches and in bilateral dialogues. It explains the Orthodox understanding of Baptism as a Sacrament, how this understanding is reflected (or not) in ecumenical agreements on Baptism. It will also review official Orthodox responses to some of these agreements. The author attempts to demonstrate that the Orthodox Church’s contributions to these sometimes-difficult dialogues have shown a commitment to seeking a common understanding of Baptism. Finally, this paper will examine the present state of ecumenical dialogue on Baptism, and evaluate its prospects for the future.
Iconostasis in the Liturgical and Church-Historical Contexts
Authors: Loyevskaya Margarita M.
Published: January 2020

The article deals with study and attribution of rare portable iconostases (“movable church”). Their features include the Sovereign tier (with the Royal Doors) absence, the small size, and the four remaining tiers (Deisis, Great Feasts, Prophets, and Patriarchs) painted on one board. Portable iconostases were used during long pilgrimages, missionary trips, or military campaigns, as well as in Bezpopovtsy (priestless) houses of worship.

In liturgical practice, both in ancient times and now, portable iconostases were used under certain circumstances for long journeys. They are easy to set up in any place, whether it is a house, a tent or a field. In the 16th century, embroidered iconostases, rapidly installable in field and stationary conditions, were brought along in military campaigns. Thus, in his military campaigns, Emperor Alexander I used a silk-painted iconostasis made by masters of the Moscow Kremlin Armory. Movable chur­ches were also used in remote and sparsely populated areas (for example, in the Olonets Governorate). The services were held in a big house and lasted for two or three days.

There were quite a lot of portable iconostases in the past, but only few of them have been preserved, among which there are rather peculiar ones, shaped as cupboards, nightstands, kiots. At the beginning of the 20th century, an iconostasis icon was painted with five tiers on one board.
