A study on relationship between the return of value/growth portfolio and market return: Evidence from Tehran Stock Exchange

This study examines the relationship between the returns of two value and growth portfolios and the return of market on 15 selected firms on Tehran Stock Exchange over the period 2008-2011. The study divides the firms into two groups in terms of the ratios of price on earning as well as price on book value into two groups of value and growth portfolios. Using some regression analysis, the study has determined a positive and meaningful relationship between value portfolio and market return when the market is on the upside but this relationship is not meaningful during the bear session. The results indicate that during the bull sessions, value portfolios provide better investment opportunities than growth ones do

Identification and Ranking of Factors Affecting Innovation in Accounting

The main goal of this research is to identify and rank factors affecting innovation in accounting. In this research, firstly, accounting specialists were selected by purposeful sampling methods, and then qualitative data were collected using open questionnaires. After analyzing the collected data using the phenomenology method, 11 factors were identified. Subsequently, a survey involving 17 faculty members from the accounting departments of Iranian public universities was conducted, and the Bayesian best-worst method was employed to rank these identified factors. Based on the results, the top 3 factors affecting innovation in accounting, in order of importance, include advances in information technology, changes in the business environment, and the level of financial knowledge and analytical skills of accountants. In order to improve the context of innovation in accounting, the results of this research suggest accountants should have general information about business and advances in information technology. They also, as the human capital of the innovation process in accounting, should continuously improve their level of financial knowledge and analytical skills.IntroductionIn recent years, the information technologies, such as cloud service models, big data, artificial intelligence, and blockchain are rapidly transforming the business environments and have raised concerns about the future of the accounting profession. Although these emerging technologies are still designed for the day-to-day work of accountants, they can significantly change the future work of accountants (Moll & Yigitbasioglu, 2019). It seems that in the face of the said technologies, the provision of accounting services, such as bookkeeping, preparing financial statements, preparing tax returns, and auditing, have all been subject to radical innovations (Bowles et al., 2020). According to the accounting literature, a new set of skills is necessary for accountants due to these emerging technologies. This is while job advertisements of Iranian companies (https://www.irantalent.com), still demand traditional job roles for accountants and instead, new job titles, such as fraud investigation specialist and senior data analyst have been emerging that can cover the newly defined job roles of accountants by literature. It seems that to reinforce the position of accountants in organizations, a change in accounting and in other words, the search for innovation in accounting is necessary.To address the lack of accounting literature in the field of innovation, the primary objective of this study is to identify and rank the factors that impact innovation in accounting by using qualitative methods, to initiate the expansion of innovative thinking and the creation of innovative ideas in accounting.MethodologyThis study used the phenomenology method to identify the factors affecting innovation in accounting. The accounting specialists were chosen as an informant using purposeful and snowball sampling methods. The twelve accounting specialists who participated in the research offered a wide range of services, including auditing, consulting, financial statement preparation, and tax accounting. Data collection was carried out mainly by means of an unstructured questionnaire supported by a telephone interview. Finally, by the use of Colaizzi’s method of data analysis, the factors affecting innovation in accounting were identified (Wirihana et al., 2018, p. 31).The Bayesian best-worst method was selected to rank the factors affecting innovation in accounting. The decision-makers were seventeen faculty members in the accounting department of Iranian public universities who had publications that transfer the concept of some sort of innovation in accounting. Bayesian best-worst method is based on pairwise comparison (Mohammadi & Rezaei, 2020). Pairwise comparison data from the decision-makers who participated in the research was collected through a standard questionnaire. Finally, using Python code for the chosen method, the factors affecting innovation in accounting were ranked.Results and DiscussionAccording to the results of Colaizzi’s method of data analysis, eleven factors were identified, and using the Bayesian best-worst method, the optimal weight of all factors was calculated. Table 1 presents the overall optimal weight and rank of factors affecting innovation in accounting. The findings indicate that the factors of advances in information technology (0.127806), changes in the business environment (0.12760311), and the level of financial knowledge and analytical skills of accountants (0.10951763) are respectively the most important factors. According to the optimal weight of all factors, it can be seen that none of the factors are irrelevant to innovation in accounting, because the weight of the least important factor is equal to 0.06665689. In fact, neither factor has an optimal weight lower than 0.065.ConclusionThe field of research into innovation in accounting is new, therefore this research generates new insight into the area. Among the practical implications, the study suggests that accountants consider environmental factors, such as advances in information technology and constantly update their knowledge and skills. It also suggests that they should improve their overall business knowledge by familiarizing themselves with different companies' operations and financial processes. Moreover, it suggests that they develop their analytical skills to be able to clarify the implications of decision-making results. Lastly, this study suggests that to achieve innovation in accounting, the conduct of research related to innovation and the cooperation of accountants can generate ideas to improve innovation in accounting.The study was qualitative in nature, as a result, this study cannot argue that the nature of innovation in accounting and the factors affecting it remain unchanged over time. Therefore, this study recommends more research in this field to contribute to a better understanding of innovation in accounting

Relationship between the double burden of malnutrition and mental health in overweight and obese adult women

The co-existence of overweight or obesity with concurrent deficiency of one or more nutrients is referred to as double burden of malnutrition (DBM), and numerous mental health impairments have been associated with a variety of nutrient deficiencies. Although DBM is relevant for several health outcomes, the ubiquitous involvement of vitamin D across multiple systems and tissues suggests D insufficiency as a viable target for nutritional modification. The present study aimed to evaluate the contribution of DBM and mental health among adult women. Study participants included 300 women, aged 18–59 years, who presented to one of the 25 health centres in Tehran. Participants with a body mass index (BMI) of greater than 25 kg/m(2) and a plasma concentration of 25-hydroxy vitamin D [25(OH)D] of >20 ng/ml were considered to have DBM. The 147-item food frequency questionnaire was used to estimate their dietary intake. Mental health status was assessed using the depression, anxiety and stress scales-21 (DASS-21). The mean ± standard deviation age, weight and BMI of the participants were 36⋅49 ± 8⋅38, 80⋅89 ± 12⋅45 kg and 31⋅04 ± 4⋅31 kg/m(2), respectively. DBM was significantly associated with stress, after adjusting for potential confounders, including age, energy and marital status in model 1 (OR = 1⋅28, 95 % confidence interval (CI) 1⋅00, 1⋅65, P < 0⋅04) v. the crude model (OR = 1⋅22; 95 % CI 0⋅96, 1⋅55, P = 0⋅09). No significant association was seen among DBM and DASS-21 outcomes. In this cross-sectional study, stress and DBM were significantly associated. While vitamin D insufficiency was associated with mental health and obesity in opposing directions. Elucidation of whether vitamin D supplementation can improve mental health impairments requires further evaluation

Corporate Governance, Investment in Research and Development and Company Performance: A Data Envelopment Analysis Approach Based on Data from a Developing Country

The aim of this paper is to investigate the role of investment in research and development (R&D) in relationship between corporate governance and company performance in the Tehran Stock Exchange. In this regard, ownership concentration and debt ratio were used as the criteria for corporate governance. The statistical population included all companies listed in Tehran Stock Exchange, 161 of which were selected as the statistical sample and investigated from 2004 until 2014. The statistical regression analysis of mixed data in the Baron and Kenny model (1986) and hierarchical regression analysis were employed to test the research hypotheses. The results indicated that corporate governance was a factor influencing company performance and R&D activities. The results also indicated that investment in R&D improved company performance. Furthermore, the research evidence showed a minor role for the R&D investment variable in mediating the relationship between corporate governance and company performance, and thus could not play a moderating role in this relationship.

Alcohol Abuse, Consequences and Treatments from the Perspective of Traditional Iranian Medicine: A Review Study

Background: Alcohol use has always been prevalent in human societies, but in many Muslim-majority countries, including Iran, national laws prohibit the consumption of this substance. Methods: In this study, reference books on traditional Iranian medicine and electronic documents from Google Scholar, PubMed, and Scopus were searched for entries about the consequences and treatments of alcohol abuse. Findings: Seminal books of traditional Iranian medicine refer to alcoholic beverages using two terms, namely, “khamr” and “sharâb” (wine). These sources indicate that the temperament of “sharâb” is generally warm but may vary depending on color, taste, concentration, and age. Traditional Iranian medicine views wine as a cause of multiple adverse effects on health. Conclusion: Traditional Iranian medicine advocates the beliefs that no level of alcohol use is beneficial for health and that physicians should advise against alcohol consumption even in small amounts. Scholars of indigenous medical practices have long been opposed to the adoption of wine as a remedy or otherwise, as they believe that the benefits of alcohol are dwarfed by its harmful effects

Sexual and reproductive health needs of HIV-positive people in Tehran, Iran: a mixed-method descriptive study

Background: People Living with HIV (PLHIV) are highly stigmatized and consequently hard-to-access by researchers and importantly, public health outreach in Iran, possibly due to the existing socio-cultural situation in this country. The present study aimed to evaluate the sexual and reproductive health needs of PLHIV in Tehran, the capital of Iran. Methods: As a mixed-method descriptive study, this project was conducted in 2012 in Tehran, Iran. In this study, we evaluated and discussed socio-demographic characteristics, family and social support, sexual behaviors, fertility desires and needs, PMTCT services, contraceptive methods, unintended pregnancy and safe abortion, and Pap smear tests among 400 participants referring to the behavioral disorders consulting centers. Results: Of the sample 240 (60%) were male and 160 (40%) were female. About 50% of women and 40% of men were 25-34 years old. More than 60% of men and 96% of women were married, while more than 50% of the participants had HIV-positive spouses at the time of study. According to the results, fertility desire was observed among more than 30% of female and 40% of male participants. Results of the in-depth interviews indicate that the participants are not satisfied with most of the existing services offered to address their sexual and reproductive health needs. Conclusion: Despite the availability of services, most of sexual and reproductive health needs of the PLHIV are overlooked by the health system in Iran. Paying attention to sexual and reproductive health needs of PLHIV in Iran not only protects their right to live long and healthy lives, but also may prevent the transmission of HIV from the patients to others within the community

Health sector spending and spending on HIV/AIDS, tuberculosis, and malaria, and development assistance for health: progress towards Sustainable Development Goal 3

Background: Sustainable Development Goal (SDG) 3 aims to “ensure healthy lives and promote well-being for all at all ages”. While a substantial effort has been made to quantify progress towards SDG3, less research has focused on tracking spending towards this goal. We used spending estimates to measure progress in financing the priority areas of SDG3, examine the association between outcomes and financing, and identify where resource gains are most needed to achieve the SDG3 indicators for which data are available. Methods: We estimated domestic health spending, disaggregated by source (government, out-of-pocket, and prepaid private) from 1995 to 2017 for 195 countries and territories. For disease-specific health spending, we estimated spending for HIV/AIDS and tuberculosis for 135 low-income and middle-income countries, and malaria in 106 malaria-endemic countries, from 2000 to 2017. We also estimated development assistance for health (DAH) from 1990 to 2019, by source, disbursing development agency, recipient, and health focus area, including DAH for pandemic preparedness. Finally, we estimated future health spending for 195 countries and territories from 2018 until 2030. We report all spending estimates in inflation-adjusted 2019 US$, unless otherwise stated. Findings: Since the development and implementation of the SDGs in 2015, global health spending has increased, reaching$7·9 trillion (95% uncertainty interval 7·8–8·0) in 2017 and is expected to increase to $11·0 trillion (10·7–11·2) by 2030. In 2017, in low-income and middle-income countries spending on HIV/AIDS was$20·2 billion (17·0–25·0) and on tuberculosis it was $10·9 billion (10·3–11·8), and in malaria-endemic countries spending on malaria was$5·1 billion (4·9–5·4). Development assistance for health was $40·6 billion in 2019 and HIV/AIDS has been the health focus area to receive the highest contribution since 2004. In 2019,$374 million of DAH was provided for pandemic preparedness, less than 1% of DAH. Although spending has increased across HIV/AIDS, tuberculosis, and malaria since 2015, spending has not increased in all countries, and outcomes in terms of prevalence, incidence, and per-capita spending have been mixed. The proportion of health spending from pooled sources is expected to increase from 81·6% (81·6–81·7) in 2015 to 83·1% (82·8–83·3) in 2030. Interpretation: Health spending on SDG3 priority areas has increased, but not in all countries, and progress towards meeting the SDG3 targets has been mixed and has varied by country and by target. The evidence on the scale-up of spending and improvements in health outcomes suggest a nuanced relationship, such that increases in spending do not always results in improvements in outcomes. Although countries will probably need more resources to achieve SDG3, other constraints in the broader health system such as inefficient allocation of resources across interventions and populations, weak governance systems, human resource shortages, and drug shortages, will also need to be addressed.

A Comparative Study of Exegetical Narrations Related to the Verse of Holy Prophet's Sin Based on the Exegetic Principles and Rules

According to exegesis, the necessary condition for the validity and accuracy of every exegetic opinion- including exegetic narrations- is their conformity with accepted exegetic principles and rules. Therefore, the comparative analysis of transmitted exegeses on the basis of the principles and rules of exegesis is an important method to examine and evaluate how much these opinions are valid and accurate. Different narrations and exegetic opinions have been proposed for the second verse of the Chapter Victory (Surah 48) in order to explain the meaning of the term "sin", its attribution to the Holy Prophet (peace be upon him and his progeny), and asking "forgiveness" for it. The present paper analyzes each of these exegetic opinions and their semantic significations and implications from different dimensions discussed in the principles of exegesis, including their conformity with lexical root in singulars and compounds, literary rules, contextual implication, verses and narrations with similar theme, necessities and admissa, and intellectual propositions, and tries to assess and evaluate the validity and accuracy of each opinion in relation to rational exegetic principles. It seems that the exegetic opinion transmitted from Imam Reza (peace be upon him) has more conformity and agreement with the principles of exegesis than other mentioned opinions.

Tuberculous Sacroiliitis after a Penicillin Injection: A Case Report

Tuberculosis is one of the major health problems in developing countries affecting different organs such as bone and joints. One of the most important involvements of osteoarticular tuberculosis is that of the sacroiliac joint. In addition, its incidence has increased over the past several years. Early diagnosis is necessary to prevent further disorders such as neurological and surgical complications. We report a tuberculous arthritis case in the right sacroiliac joint, which developed after penicillin injection.The patient was a 32-year-old man admitted to Besat hospital, Tehran, Iran. He complained of pain, erythema and swelling in his right buttock starting approximately 17 years previously, after a penicillin injection, which was followed by the emergence of an orifice with yellow secretions. Over the years, the secretions continued but the pain, swelling and erythema were resolved. At the time of admission, his vital signs were stable and normal. In the physical examination, an orifice with a small amount of yellow secretion was detected on the right buttock as claimed by the patient. Lung auscultation was clear. No lymphadenopathy was detected. Laboratory data were normal. During hospitalization, initial antibiotic therapy was prescribed. After Mycobacterium tuberculosis was detected in culture, a 4-drug anti-TB therapy encompassing rifampin, isoniazid, ethambutol and pyrazinamide was prescribed for 18–24 months, in addition to daily vitamin B6 and pantoprazole
