Enterprise resource planning (ERP) system implementation in a manufacturing firm: Rationales, benefits, challenges and management accounting ramifications
Authors: Weerasekara Udani , Gooneratne Tharusha
Published: April 2023

Research Question: What are the accounting benefits perceived by accountants and internal auditors that entail through Enterprise Resource Planning (ERP) systems? Is there an interaction of ERP accounting benefits with the accountants’ and internal auditors’ satisfaction level in using ERP systems? Motivation: Many organizations are implementing ERP systems extensively while sharing a common database and being real-time. Past scholars summon empirical studies on ERP's impact on accounting benefits and user satisfaction. Therefore, this study was conducted from accountants’ and internal auditors’ perspective as recent scholars shed light on the cruciality of these two groups' perceptions as key ERP users. Idea: This study examines the accounting benefits that entail through the adoption of ERP systems by Sri Lankan companies with regard to ERP user satisfaction from the perspective of accountants and internal auditors. Data: The data were collected from 38 accountants and 19 internal auditors across 24 companies that are implementing ERP systems for more than four years. Tools: A quantitative survey methodology is employed to draw empirical evidence. Findings: The findings confirm that organizational, operational (time), and IT accounting benefits derived from ERP systems significantly and positively influence ERP users' satisfaction. In contrast, operational accounting benefits (cost) received the lowest rating and did not significantly influence user satisfaction. Contribution: While these findings are valuable to accountants and internal auditors to better understand the ERP accounting benefits, ERP consultants and system providers also benefit from identifying ERP accounting features to uplift user satisfaction in developing countries.
Cash-based credit risk model based on Timothy Jury’s template: review and modification with application to manufacturing company (2016-2022)
Authors: Litvinenko Alexey , Alver Jaan
Published: April 2023

Research Questions: 1) Can the newly developed by the author methodology based on Timothy Jury’s credit risk analysis provide sufficient visibility of the company’s financial situation and creditworthiness? 2) Can such methodology based on Timothy Jury’s credit risk analysis be a trustworthy indicator of production company bankruptcy and the likelihood of default? Motivation: nowadays financial institutions use an accrual-based credit risk model for the analysis of the creditworthiness of the companies, however, such models are not always trustworthy due to the data manipulations in the accrual financial statements. Since the cash flow financial statement is more reliable for the determination of the probability of default, the authors developed the cash-based credit risk model and applied it to the production company for the analysis of its likelihood of default. Idea: This paper looks at Timothy Jury’s little-known methodology of credit risk analysis and its underlying template, and proposes a version that the authors improved in accordance with the requirements of International Financial Reporting Standards (IFRSs). The authors used improved methodology for the analysis of a manufacturing company to find out the company’s pre-bankruptcy situation and reveal the likelihood of credit risk default. Data: the company analyzed is a publicly listed production company Linas Agro Group with its shared traded at Nasdaq Baltic. The data for the research was taken from the annual reports, managerial reports, and the auditor’s reports issued for seven years 2016–2022. Tools: Timothy Jury’s cash-based analysis template was modified by the authors into the credit risk model. Findings: the results show that the modified cash-based credit risk model provides sufficient visibility of the company’s likelihood of default and specifies the actual source used to cover the debt. The analysis has shown that the production company paid significant dividends with negative cash available to satisfy capital providers. Contribution: the present article contributes to the knowledge base about cash flow and credit risk. The article encourages an academic society to further research the topics related to cash flow and cash flow theory, which is currently less researched than accrual-based theory. The article is also beneficial for business owners, investors, and finance professionals to improve investment decision-making, for bank managers to diminish the number of bad loans and for the auditors to determine the pre-bankruptcy state of the company more precisely using the cash-based credit risk model presented in this article.

Published: April 2023

Background:

Atypical presentation of calcinosis cutis in the context of COVID-19 infection complicated by acute renal failure has not been described in literature. We report a case of severe COVID-19 infection and its associated uncommon skin manifestation. It is a rare condition and its association with different diseases has been established in the past. However, to the authors’ knowledge, calcinosis cutis has not yet been described in relation to COVID-19 infection complicated by acute renal failure.

Case Presentation:

Here we describe a case of a 55-year-old gentleman admitted to the intensive care unit with severe COVID-19 infection whose hospital stay was complicated by acute renal failure and development of hypocalcemia which was treated with oral and intravenous calcium. Subsequently, he developed an atypical fleshy lesion on his left ankle during his in-patient stay which was histologically proven calcinosis cutis. It was successfully treated with topical medications.

Conclusion:

This case highlights the importance of considering a wide differential of skin lesions including calcinosis cutis in patients who are critically unwell with COVID-19 or any other severe infections and develop isolated skin lesions in the setting of impaired renal functions and abnormal calcium phosphate metabolism with calcium administration.

Legalizar ou não legalizar as drogas no Brasil?
Authors: Diehl Alessandra , Ribeiro Hewdy Lobo
Published: April 2023

A Comissão Global de Políticas de Drogas em 2011 anunciou que a “guerra contra as drogas falhou” e a legalização das drogas seria uma das respostas para conter o tráfico, à violência, o excessivo encarceramento e o consumo de drogas entre os mais jovens. No entanto, reforça-se a estrita necessidade de analisar a questão a partir de uma perspectiva científica de quais seriam os hipotéticos benefícios que resultariam da legalização das drogas, principalmente para a saúde pública. Assim, este artigo tem por objetivo de forma resumida apontar alguns dos principais pontos baseados em evidências que reforçam que a legalização as drogas neste momento no Brasil é atitude no mínimo precipitada, descuidada e errônea.

Obesity is a well-known risk factor of metabolic complications and cardiovascular disease. Associations between anthropometric measurements and fat distribution and risk factors  for cardiovascular disease have been demonstrated in several populations.
To study the association of various measures of  body mass index (BMI), waist circumference (WC), percentage of body fat (%BF), with leptin, Adiponectin, and paraoxonase. To study the association between leptin , adiponectin with Paraoxonase.
This study conducted from  of  February 2013 until March 2014, all individuals were randomly recruited from Kirkuk and Tikrit Governorate .Hormonal assay of leptin, adiponectin, Paraoxonase, and glucose. Blood samples collected from 220 individuals, and these samples were divided into three groups according to BMI. Group 1  (Normal Weight group  n=80), Group 2 (Over Weight group, n=58), Group 3 (Obese group, n=62) .
The statistical analysis (students t-test) exhibited significant (P≥ 0.0001)elevation for leptin , paraoxonase, and glucose, while significant decrease in adiponectin in over weight and obese groups compared with normal weight groups.
The correlation coefficient (r) between Leptin and other parameters were calculated with regression plot showed a negative correlation with adiponectin, and  paraoxonase in over weight and obese group. There was a positive correlation between adiponectin with paraoxonase, but a negative correlation with leptin, in over weight and obese group.
 Conclusion: Adiponectin as hormone play an important role in the prevention of hyperlipidemia, and consequently atherosclerosis and its complications while Leptin act as atherosclerotic factors. The results indicated that adiponectin positively associated with paraoxonase while Leptin negatively correlated with paraoxonase.

Authors: Nuha S. Al-Bayatii  , Fatima Sh.Al-Naserii  , JaladetM.S.Jubrael
Published: April 2023

Leishmania parasites are the causal agents of leishmaniasis, a group of protozoan diseases transmitted to mammals, including human beings, by phlebotomine sandflies. In culture media (at 25-28̊C ,pH =7.2-7.4),leishmania parasites develop as motile promastigotes similar to those found in the sand fly midgut . Traditionally media available do not meet the requirement for the bulk cultivation of Leishmania parasites ,it requires fetal calf serum (FCS),that is very expensive and not easily available in the market. A number of studies have shown that the addition of 5-10 %  normal human urine stimulates growth, leading to more rapid multiplication and a higher concentration of parasites .Urine from patients with bladder cancer were used in this study to determine the effect of Epidermal growth factor ( which is increased in level in this type of urine),and our study showed that proliferation indexes were significantly increased in the culture media supplemented with  human urine from patients with bladder cancer, we undertook a detailed study of such an effect in old world Leishmania isolates causing cutaneous Leishmaniasis. We also found that urine with high percentage of EGF. Could be used as an alternative of fetal calf serum.
