Published: March 2020

This study aims to examine the effect of operating performance and autonomy on the financial performance of local government with budget effectiveness as an intervening variable. The ratio of local government revenue growth is used as a proxy for the financial performance of local government. The unit of analysis of this study includes the financial statements of 29 regency governments and 6 city governments in Central Java Province, Indonesia, for three periods from 2015 to 2017. The results of this study indicate that operating performance and autonomy have a positive effect on the financial performance of a local government. This study provides empirical support for the implementation of the new public management theory to improve the financial performance of local governments, especially in increasing local own-source revenues. However, the results show that budget effectiveness is not able to mediate an increase in the influence of operating performance and autonomy on the financial performance of the growth of local government revenues.

Authors: Winten Adnyano Wayan , Abdul Chalid Dony
Published: March 2020

The airline operating cost may vary along the operation time of the aircraft. This cost fluctuation should be taken as consideration for the decision-making process, for instance, the pricing calculation. A poor costing might distort pricing leading to a loss of business. A long-term oriented cost calculation to forecast the total cost of aircraft during the operation time is critical for the airline company. This research will study whether the life cycle cost analysis is fit for airline company with an emphasis on maintenance and disposal or aircraft redelivery cost and focus on aircraft operating lease context. It uses a case study framework on an airline in Indonesia with the interview and documentation analysis as the main research method. The life cycle cost is found to be fit for the airline company with activity-based life-cycle costing as the applicative model.

The Impact of Operational and Financial Hedging to the Airline Operating Performance
Authors: Dewikristi Siallagan Sitauli , Prijadi Ruslan
Published: March 2020

The airline is a low-profit margin and high competition industry. Increasing competition makes airline unable to easily charge their costs to customers and raise their fare,  so that airlines have a narrow profit margin. One of the major costs in the airline industry is jet-fuel cost. International Air Transport Association (IATA), predict that total global fuel cost for period 2019 will rise to USD 200 billion from about USD 180 billion in 2018. In average, Jet fuel will contribute 24.2 percent of total 2019 Airline’s operating cost (IATA [1]). Like most of commodities, jet-fuel price is highly volatile which encourages companies to engage in hedging activities. This paper examines the impact of operational and financial hedging to airline operating performance. We perform an empirical study by using the airline data from 2013 to 2017. To test the impact of hedging in airline operating performance, we regress the operating cost to revenue ratio, operational hedging, financial hedging and other control variables. This study found that financial derivative hedge can reduce the dollar needed to generate airline revenue, while operational hedging increase it.

Authors: Fajarini Sri Wahyuningrum Indah , G. Djajadikerta Hadrian
Published: March 2020

The objective of this paper is to examine the relationship between company financial performance, company characteristics and non-financial performance disclosure (NFPD) in terms of quantity and quality. This paper uses a NFPD index that covers six perspectives: three perspectives of the Balanced Scorecard (BSC) and three perspectives of Environmental, Social and Governance (ESG) disclosure. The sample data used in this study is 30 Australian listed companies in 2014. The results show that in terms of quantity, there is a significant relationship between company financial performance (Return on Equity-ROE and Earning per Share-EPS), company type, company age, auditing firm and non-financial performance disclosure while Return on Asset (ROA) and size of company shown no significance. Meanwhile, in terms   of quality, only ROE and company age were significantly related to non-financial performance disclosure. Overall, by using the six perspectives of non-financial performance disclosure in the 30 companies in Australia, this study has contributed new understandings to the main corporate social disclosure studies focused on non-financial performance disclosure, which should motivate companies to produce and disclose annual and sustainability reports that are more comprehensive and highly credible.

A study of Effects and implications of differences between Indian GAAP and IFRS
Authors: Srivastava Anubha
Published: March 2020

Economic growth in any economy requires sustainable high-quality financial reporting standards. However in the era of globalization, with rapidly changing rules and regulations in accounting world, Indian financial reporting system too cannot be isolated from the global developments. Lack of standardization in different accounting standards imposes a financial burden on all the stakeholders, which includes both internal as well as external burden to an organization. It is also too cumbersome for investors to compare the financial statement of corporates if they follow different accounting policy. It was felt that there should be one global set of accounting standards for all. Thus IASB came in existence and formulated IFRS. IFRS is high-quality principle-based accounting standard which aims to bring uniformity comparability and transparency in accounting world. In India the conversion process has started in 2015-16 onwards where all the accounting standards will be gradually fully converged with IFRS and will be named as Ind as. This paper attempts to find out the key difference among IFRS, Indian GAAP and ind AS and its implications. A questionnaire survey has been conducted to find out the implication of differences. The paper concludes that adoption of IFRS would benefit the economy in all aspects.

Published: March 2020

Pesquisa realizada por meio do projeto PIBIC/PUCPR em 2010 com cruzamento de dados referentes de como o Estado através da escola agiu com violência e violência simbólica em relação à etnia alemã e seus descendentes. Tendo como objetivo perceber como as escolas étnicas alemãs mantinham a identidade através da língua vernácula; perpetuavam sua cultura e o sentimento nacional de origem; sendo que essas escolas foram alvo da política de nacionalização do Estado Novo que tinha como objetivo nacionalizar todos os imigrantes e descendentes através da obrigatoriedade do uso exclusivo da língua portuguesa através da proibição da língua de origem, exaltando a cultura nacional brasileira e da imagem de Getúlio Vargas. Através de análises de fontes bibliográficas sobre a etnia alemã, nacionalização, Estado Novo, etnicidade, relações de poder e violência simbólica como Max Weber (1982), Pierre Bourdieu (2010), Getulio Vargas (1943), Relatórios de Governo de 1932 a 1949, Arquivos da Delegacia de Ordem Política e Social (1930 a 1940), entrevistas com alemães e descendentes que vivenciaram ou relataram vivências durante o período de nacionalização compulsória; conclui-se que uma política de Estado ditatorial utilizando as escolas, a inspeção escolar agiu com violência e poder simbólico. Forçando a inclusão a cultura local e através de poder legal e tradicional tenta quebrar signos culturais de origem impondo uma nova ordem educacional e sócio-cultural.Palavras-chave: Escolas étnicas.

Verificar se existe correlação entre a medida antropométrica de coxa com a força muscular em 10 repetições máximas (10RM) no exercício de cadeira extensora. Foram selecionadas 16 mulheres treinadas (idade: 20 ± 6 anos) para a mensuração dos dados antropométricos e avaliação da força de 10RM. Os avaliados foram orientados de forma padronizada para garantir maior uniformidade dos valores. Foram realizadas três tentativas a fim de se achar a carga de 10RM. Toda a coleta de dados foi realizada em um dia. Após a coleta dos dados, foram realizados os trabalhos estatísticos, os quais possibilitaram ver se os dados eram paramétricos ou não paramétricos. Com os resultados pode-se observar que não ocorreu correlação entre os valores de perímetro de coxa e força de 10RM, visto o valor r = -0,2271. Isso revela uma correlação moderada negativa de acordo com a tabela de correlação de Pearson. Pode-se concluir que não ocorreu correlação entre a perimetria de coxa e a força de 10RM, ou seja, a força na amostra ocorre não só por questões de espessura do segmento, e pode sofrer influência de outros fatores, como adaptação neural e composição corporal.

Modern medicine has made significant advances in the treatment of fungal infections. The problem of drug resistance of such a common conditional pathogen as Candida remains relevant for the last decade. The aims of the study were: 1) analysis of species and strain drift of Candida in patients with HIV/AIDS from oropharynx and intestine in two years; 2) the analysis of the dynamics of the sensitivity of Candida to standard antimycotic drugs. Treatment of candidiasis in HIV-infected patients leads to changes in the species and strain composition of Candida. After eradication of C. albicans which is sensitive to fluconazole, more resistant strains of other species (glabratae, krusei. tropicalis) takes its place in the biotope, which is one of the reasons for the low effectiveness of antimycotic therapy.

Based on information from the registers of the tuberculosis monitoring system in Moscow for 2014-2015. A comparative analysis of indicators for patients with tuberculosis was conducted with the presence and absence of co-infected HIV infection. The results showed that among patients with tuberculosis combined with HIV infection, patients from the city’s permanent population, from the age group of 31-40 years old, non-working, injecting drug users are much more likely than other TB patients. The number of tuberculosis patients who died of HIV infection, in comparison with the number of patients who died from tuberculosis, accounted for more than a third of the total number of tuberculosis-related deaths. Thus, when assessing the epidemiological situation of tuberculosis, it is necessary to take into account the significant contribution of HIV infection to the values of the main indicators and their dynamics.

At present, the category “risk” becomes one of the main paradigms of epidemiology. A large number of applied studies on the specific characteristics of risk factors for individual nosological forms of the infectious and noninfectious morbidity have been published. At the same time, there is a minimum of publications of a general pattern concerning the theoretical basis for the application of this epidemiological category. The lack of integral classification system is one of “gaps” in epidemiology. In connection with this, the purpose of the submitted report is the theoretical systematization of types of epidemiological risk and presentation of their estimated characteristics. Authors systematized main types of epidemiological risk which are widely used in population and clinical studies. In this report estimated characteristics for each of separate types of epidemiological risk for use are provided in population studies.

Authors: Patoari Md. Manjur Hossain
Published: March 2020

To create generation by maintaining family and social binding, marriage is the only legal way which is recognized by society, civilization, country and religious. All religious encourage both man and woman to marry. But this legal tie is untied by way of divorce. In consequences of divorce a bride have to return to her parental home which is not considered as respectable in the society of Bangladesh and the situation may be more difficult if parents are not alive or in poverty. Though divorce is a right of a man or a woman and he or she can legally terminate his or her conjugal life by divorce but in Bangladesh currently it has reached in such extreme level that it has become a matter of great concern. To some extent divorce relief a man or a woman from endless sufferings but most of the cases it broken dreams, hopes and aspiration of a family, causes intolerable sufferings and push their offspring future uncertainty. The prime object of this research is to trace out the connection of divorce by women and socio-economic and culture of Bangladesh. This research also attempts to find out effects of divorce on the victims, their children and also in the family and society.

Background: On late December 2019, a viral pneumonia known as coronavirus disease 2019 (COVID-19), was originated from China and spread very rapidly in the world. Therefore, COVID-19 became a global concern and health problem. Methods: We presented four patients in this study. They were selected from patients who presented with pneumonia symptoms and were suspicious for COVID-19 and referred to the intended centers for COVID-19 diagnosis and management of Shiraz University of Medical Sciences in the south of Iran. Two nasopharyngeal and oropharyngeal throat swab samples were collected from each patient and tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection by real-time reverse-transcriptase–polymerase-chain-reaction (RT-PCR), and also samples were sent for influenza viruses and all the respiratory panel. Results: In the present report, four patients were diagnosed in the starting days of COVID-19 disease in our center in south of Iran with co-infection of SARS-CoV-2 and influenza virus. Conclusions: This co-infection of COVID-19 and influenza highlights the importance of considering SARS-CoV-2 PCR assay regardless of other positive findings for other pathogens in the primary test during the epidemic.

During 2010, at the Facultad de Medicina Veterinaria y Zootecnia of the Universidad Nacional Autónoma de México (fmvz-unam) we analyzed the influence of metadata over its website according to the search engines used by the academic community. This document serves only the second specific objective of the research: to know the academic profile, the informative behavior and the veterinary information needs of the academic community of the fmvz-unam. The methodological tool was the design and implementation of an online survey. We received 215 responses, two thirds answered academic staff, the rest, undergraduate and postgraduate students. In relation to information behavior, an Internet-usage index was developed, with which it was determined that 64 % of this community uses four or five information services on the Internet, This means that the network is widely used to seek information and as communication media. This community search for more veterinary information related to dogs, dairy cattle and sheep, compared to other animal species; while animal welfare, zoonosis and molecular biology are the topics of greatest interest.
Treatment of COVID-19 with Individualized Immune Boosting Interventions
Authors: Doss Mohan
Published: March 2020

There are major concerns regarding the current global pandemic of coronavirus disease 2019 (COVID-19) caused by the coronavirus SARS-CoV-2. Whereas most of the infected individuals have no symptoms or only mild symptoms, in a small minority, the infection can lead to pneumonia and death. One major concern regarding the pandemic is the 2.3% average case fatality rate of the COVID-19 patients, with the fatality rate increasing to 8% for patients aged 70 to 79 and 14.8% for those aged 80 and over. Another major concern is the person-to-person transmission of the coronavirus by asymptomatic individuals during the incubation period, making it difficult to limit the spread of the disease. Many steps are underway worldwide to limit the spread of the disease, e.g. cancellation of conferences and large gatherings, closure of schools, curtailment of travel, etc. Considering the magnitude of the adverse impact on the social, cultural, commercial, educational, scientific, health, and other aspects of the society from such steps and the large anticipated casualties with the expected spread of the disease worldwide, it is important to explore methods of reducing the fatality rates of COVID-19 patients. Since the weakness of the immune system is one of the major contributing factors for the occurrence of pneumonia, and inflammation contributes to increased mortality rates of pneumonia patients, interventions that improve the immune response and/or reduce inflammation may reduce the pneumonia incidence and mortality in COVID-19 patients. There are indeed a large number of interventions that improve the immune response and/or reduce inflammation. However, all the interventions would not be applicable or acceptable to everyone and so the interventions would need to be individualized based on individual circumstances and preferences. This approach, known as “Individualized Interventions to Improve the Immune Response”, or the I4R approach needs to be tested in pilot clinical trials for the treatment of COVID-19 patients. If the pilot clinical trials demonstrate that it is effective in reducing the incidence and mortality due to pneumonia, widespread adoption of the I4R approach for treating COVID-19 patients may reduce their morbidity and mortality, reducing the concerns regarding the coronavirus. This may be helpful in reducing the need for the drastic steps that have been taken worldwide, and help in the return of life to normalcy. Therefore, clinical trials of the I4R approach should be conducted on an urgent basis.

Objective: Racial/ethnic disparities in infant mortality (IM) continue to persist in the United States, with Black/African Americans (AA) being disproportionally affected with threefold increase in mortality compared to Whites. Epidemiologic data have identified maternal characteristics as risk IM such as eclampsia, maternal education, smoking, maternal weight, maternal SES, and family structure. Understanding the cause of causes including the method of labor and delivery and the racial heterogeneity may facilitate intervention mapping in narrowing the Black White IM risk differences. We aimed to assess the temporal/racial trends and the methods of delivery, mainly vaginal versus cesarean section (C-section) as exposure function of IM.

Methods: The United States linked Birth/Infant Death records (2007-2016) were used with a cross-sectional ecologic design. The analysis involved chi squared statistic, incidence rate estimation, and period percent change.

Results: Of the 40,445,070 births between 2007 and 2016, cumulative mortality incidence was 249,135 (1.16 per 1000). The IM rate was highest among Black/AA (11.41 per 1000), intermediate among Whites (5.19 per 1000), and lowest among Asian /Pacific Islanders (4.24 per 1000). The cumulative incidence rate difference, comparing vaginal to cesarean procedure was 1.73 per 1000 infants, implying excess IM with C-section. Compared to C-section, there was a 31% decreased risk of IM among mothers with vaginal delivery, rate ratio (RR) = 0.69, 95% CI 0.64-0.74. Racial disparities was observed in the method of delivery associated with IM. Black/AA mothers with vaginal delivery had a 6% decreased risk of IM compared to C-section, RR = 0.94, 95%CI 0.92-0.95, while Whites with vaginal delivery had a 38% decrease risk of IM relative to C-section, RR= 0.68, 95%CI 0.67-0.69, p<0.001.

Conclusion: Infant mortality varied by race, with Black/AA disproportionally affected which is explained in part by labor and delivery procedures, suggesting reliable and equitable intrapartum assessment of Black/AA mothers during labor.
