This study aims to determine how the forecasting of banking stock performance in 2017 is measured weekly using the ARCH-GARCH method. There were 43 registered banking companies listed on the Indonesia Stock Exchange, but only 39 companies used as the research sample based on data completeness. The ARCH-GARCH method was used in the forecasting process. Results showed that the value of the mean absolute per cent error was 8.52% or below 10%. Therefore, the ARCH-GARCH method was quite good at predicting the performance of the banking sector. With a high level of complexity, the ARCH-GARCH method could provide a more realistic description than other methods to help investors make decisions. The banking sector tends to experience a downturn. Thus, it would be better for investors to hold back the intention to invest in banking stocks unless they are the risk-takers.

The Relationship

The research aims to test the relationship between accounting conservatism and hedging in the Iraqi banking sector. The research dealt with a sample of (12) banks listed in the Iraqi Stock Exchange from 2009-2019, with (132) views, and the(unconditional) accounting conservatism was identified. As an independent variable andaccounting hedging as a dependent variable, the (unconditional) accountingconservatism was measured through the market value model to the book, while the accounting hedging was measured as a dummy dust, and the results indicated a statistically significant correlation between accounting conservatism and accounting hedging.  orientation of the study sample towards proactive accounting conservatism according to its unconditional scale leads to a reduction in the adoption of accounting hedging tools in managing the risks of financial instruments. The reason for this may be due to the presence of a high level of accounting conservatism that makes the bank safe sort of a lot of dangers. Which contributes to reducing reliance on accounting hedging tools.However, this relationship turns out to be negative, that is, the increasing

The goal of this paper is to estimate the productive efficiency of Argentine banks. For this purpose, panel data of the universe of banks under the supervision of the Central Bank of the Republic of Argentina (BCRA) has been collected. In order to build the bank´s indicators, we used a database of 66 institutions, with annual information for the period 2009-2013. The sources of information were both the BCRA´s web site (www.bcra.gov.ar), and the Buenos Aires Stock Exchange´s web site (www.bolsar.com). It has been selected an efficiency indicator ranging between 0 and 1, meaning the lowest and highest level of efficiency, respectively. The concept of efficiency used here is a relative one, because it considers a Bank´s performance in relation to the behavior of the best players in the industry, being the latter the base of the industry benchmark or frontier. The results show that the mean efficiency of Argentine banks is 0,8277 in the specific period under consideration. The comparison with the results of other studies relating efficiency and competitive pressure, didn´t allow us to infer that the Argentine banking industry experienced in the period a high level of competition.

Measures Of Performance

This paper investigates the link between stock performance of the listed commercial banks in the Turkish stock exchange and three measures of bank performance, such as technical efficiency, scale efficiency and productivity for the period 1998-2008. The relationship between efficiency and stock returns is investigated by running a regression of stock returns on measures of performance and some bank specific variables. The results indicate that the changes in three measures of performance have positive and significant effect on stock returns, suggesting that stocks of technical efficient, scale efficient and productive banks tend to outperform their inefficient and unproductive rivals.

<div><div><div><p>Peroxides play a central role in many chemical and biological pro- cesses such as the Fenton reaction. The relevance of these compounds lies in the low stability of the O–O bond which upon dissociation results in radical species able to initiate various chemical or biological processes. In this work, a set of 64 DFT functional-basis set combinations has been validated in terms of their capability to describe bond dissociation energies (BDE) for the O–O bond in a database of 14 ROOH peroxides for which experimental values ofBDE are available. Moreover, the electronic contributions to the BDE were obtained for four of the peroxides and the anion H2O2− at the CBS limit at CCSD(T) level with Dunning’s basis sets up to triple–ζ quality provid- ing a reference value for the hydrogen peroxide anion as a model. Almost all the functionals considered here yielded mean absolute deviations around 5.0 kcal mol−1. The smallest values were observed for the ωB97 family and the Minnesota M11 functional with a marked basis set dependence. Despite the mean deviation, order relations among BDE experimental values of peroxides were also considered. The ωB97 family was able to reproduce the relations correctly whereas other functionals presented a marked dependence on the chemical nature of the R group. Interestingly, M11 functional did not show a very good agreement with the established order despite its good performance in the mean error. The obtained results support the use of similar validation strategies for proper prediction of BDE or other molecular properties by DF Tmethods in subsequent related studies.</p></div></div></div>

The article presents the genetic characteristic of the Chukchi reindeer breed. The object of the study was of the Chukchi reindeer. In recent years, the number of reindeer of the Chukchi breed has declined sharply. Reduced reindeer numbers could lead to biodiversity loss. The Chukchi breed of deer has good meat qualities, has high germination viability and is adapted in adverse tundra conditions of Yakutia. Herding of the Chukchi breed of deer in Yakutia are engaged only in the Nizhnekolymsky district. There are four generic communities and the largest of which is the agricultural production cooperative of nomadic tribal community «Turvaurgin», which was chosen to assess the genetic processes of breed using microsatellite markers: Rt6, BMS1788, Rt 30, Rt1, Rt9, FCB193, Rt7, BMS745, C 143, Rt24, OheQ, C217, C32, NVHRT16, T40, C276. It was found that microsatellite markers have a wide range of alleles and generally have a high informative value for identifying of genetic differences between animals and groups of animal. The number of identified alleles is one of the indicators of the genetic diversity of the population. The total number of detected alleles was 127. The Chukchi breed of deer is characterized by a high level of heterozygosity, and the random crossing system prevails over inbreeding in the population. On average, there were 7.9 alleles (Na) per locus, and the mean number of effective alleles (Ne) was 4.1. The index of fixation averaged 0.001. The polymorphism index (PIC) ranged from 0.217 to 0.946, with an average of 0.695.

Background:The lipid paradox is termed the decreased cholesterol level in rheumatoid arthritis (RA). Nevertheless, the apolipoprotein levels are usually higher than a healthy person and are predictors of cardiovascular events.Objectives:We aimed to describe lipid abnormalities in RA patients and to look for predictor factors of these changes.Methods:The prospective study was carried out on patients with RA who met the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria. These patients were followed in the rheumatology department of the Kassab Institute.We collected the socio-demographic data, biological and immunological parameters.The lipid assessment included: a measurement of total cholesterol (TC), HDL, LDL, and triglycerides (TG). Lipoproteins APOA1 and APOB were measured. All data were collected after patient consent.Results:Of the 47 patients recruited, 78.7% were female. The mean age was 52.5 ±11.06 [32-76]. The average RA progressed from 86.25 ±63 months [5-288] and was erosive in 81.6% of cases. The rheumatoid factor (RF) was positive in 57.8% of patients, and citrullinated antipeptide antibodies (ACPA) were present in 62.2%. Eight patients had a previous CV history.Mean TC was 4.42 ±1.3 [1.2-7.58], mean HDL was 1.38 ±0.73 [0.18-4.10], mean LDL was 2.55 ±1.16 [0.24-5.54]. The mean TG value was 1.28 ±0.6 [0.24-5.54]. TC elevation was found in 9.1% of cases, HDL in 21.3% of cases, LDL in 5.5% of cases, and TG in 16.4% of cases. Mean APOB/APOA1 ratio was 0.67 ±0.18 [0,46-1,11]. LDL elevation was associated to a high DAS28 (p=0.06, r=0.512). APOA1 was associated to a low DAS28 (p=0.04, r=-0.642).The mean value of APO A1 was 1.36 ±0.21 [0.84-1.81], that of APOB was 0.90 ±0.22 [0.58-1.40]. APOA1 values were lower in patients with high-level LDL (p=0.767). The APOB value was associated with lipid disturbance without significant correlation (p=0.291).Conclusion:Lipid test abnormalities can be found in RA patients outside of any known CV risk factors. APOA1 seems to have a protective effect. Screening and treatment of these abnormalities can prevent CV risk.References:[1]Miguel Bernardes and al.

It is widely believed that the financial system is dependent on the banking industry, and its strength and development are vital for economic prosperity. This paper tried to show the financial performance of Iranian banks listed on the Tehran Stock Exchange (TSE) during 2013–2019, as the research population. The statistical population included 18 banks listed on the TSE from 2013 to 2019, which were sampled using a screening method. The results indicated a significant relationship between explanatory variables of capital ratio and the financial performance of banks in all models. However, a significant negative relationship was found between the inflation rate and the financial performance of banks in all models. Furthermore, it seems that banks with high asset strength are more profitable than the others. Regulators should guarantee that banks remain highly capitalized for a viable banking sector in Iran.
