This article analyzes the relationship between Bitcoin and the stock market by using a vector autoregressive model. To enhance the impulse response signal, the Sliding Window technique is applied. Study results show the relationship between Bitcoin and the stock market. First, the S&P 500 has a relatively significant effect on Bitcoin, while the influence caused by the S&P 500 is weak. In addition, after involving the Sliding Window technique, the effects caused by the standard deviation of the S&P 500 and the mean of the Dow Jones are remarkably strong on the mean of Bitcoin and the standard deviation of the S&P 500 has a comparatively significant effect on the standard deviation of Bitcoin as well. Generally, the S&P 500 and the Dow Jones indexes have an advantageous effect on Bitcoin. Financial investment can be made based on this model and conclusion.

Vitiligo is a skin pigmentation disorder that is caused by a loss of melanocytes, characterized by white spots around certain parts of the body. The aim of this study was to investigate the relationship between digit length, digit (2D:4D) ratio and vitiligo among vitiligo patients within a south-southern Nigeria. Informed consents were obtained from 98 vitiligo adult subjects (69 females and 29 males) in the age range of 18 – 50 years. The measurements that were obtained were the digit lengths of second and fourth fingers for both hands using the digital vernier caliper. The mean and standard deviation values were calculated for all measurements. A Pearson correlation was used to analyse the relationship between the various measurements for both hands in the study. Results showed that the mean ± standard deviation of the various parameters for the female category. Right 2D length was 6.67± 7.53cm, left 2D length was 6.68 ± 7.32cm, right 4D length and left 4D length were 6.86 ± 8.57cm and 6.89 ± 8.50cm respectively. While, the mean and standard deviation values for right and left 2D:4D ratios for the female category were 0.98 ± 0.15 and 0.98 ± 0.12 respectively. In the males, right 2D length was 6.66 ± 9.66cm, left 2D length was 6.64 ± 9.86cm, right 4D length and left 4D length were 6.99 ± 10.09cm and 7.03± 10.40cm respectively. While, the mean and standard deviation values for right and left 2D:4D ratios for the male category were 0.95 ± 0.03 and 0.95 ± 0.03 respectively. In the females for the right hand, there was a significant positive correlation between 2D length and 4D length (r = 0.761, p = 0.000) while there was a significant negative correlation between 4D length and digit ratio (r = -0.473, p = 0.000) at p < 0.01. For the left hand, there was a significant positive correlation between 2D length and 4D length (r = 0.783, p = 0.000). In the males for the right hand, there was a significant positive correlation between 2D length and 4D length (r = 0.976, p = 0.000). For the left hand, there was a significant positive correlation between 2D length and 4D length (r = 0.981, p = 0.000).It can be concluded that the knowledge of 2D:4D ratio among vitiligosubjects could be helpful in clinical anthropometry however, more research has to be done considering that the sample size of this study is relatively small.

The mean and standard deviation over 24 h for 3 groups of animals - active, intermediate and inactive - in physical activity units were 10948 ± 3360, 2611 ± 1973 and 484 ± 316 respectively. The differences were significant ( P = 0·004), demonstrating the ability of the method to distinguish between groups that can be visibly differentiated. The small within-animal physical activity standard deviation (18·85 PAU) obtained in another group, suggests that it also yields reliable physical activity measurements for non-human primates. The monitoring device used can discriminate between individual nonhuman primate physical activity levels in a free-living environment and does not alter daily behaviour. This makes possible the study of the relationship between physical activity and atherosclerosis in nonhuman primates.

AbstractThe purpose of this work was to study the relationship between self-focused attention and mindfulness in participants prone to hallucinations and others who were not. A sample of 318 healthy participants, students at the universities of Sevilla and Almería, was given the Launay-Slade Hallucinations Scale-revised (LSHS-R, Bentall & Slade, 1985). Based on this sample, two groups were formed: participants with high (n = 55) and low proneness (n = 28) to hallucinations. Participants with a score higher than a standard deviation from the mean in the LSHS-R were included in the high proneness group, participants with a score lower than a standard deviation from the mean in the LSHR-R were included in the second one. All participants were also given the Self-Absorption Scale (SAS, McKenzie & Hoyle, 2008) and the Southampton Mindfulness Questionnaire (SMQ, Chadwick et al., 2008). The results showed that participants with high hallucination proneness had significantly higher levels of public (t(80) = 6.81, p < .001) and private (t(77) = 7.39, p < .001) self-focused attention and lower levels of mindfulness (t(81) = -4.56, p < .001) than participants in the group with low hallucination proneness. A correlational analysis showed a negative association between self-focused attention (private and public) and mindfulness (r = -0.23, p < .001; r = -0.38, p < .001 respectively). Finally, mindfulness was found to partly mediate between self-focused attention and hallucination proneness. The importance of self-focused attention and mindfulness in understanding the etiology of hallucinations discussed and suggest some approaches to their treatment.

Background: The practice of hand washing is a simple effective way to prevent infection cleaning of the hands can prevent the spread of germs and micro organisms. Hand hygiene is recognized as a leading measure to prevent cross –transmission of microorganism. Infection due to microbes is a evolving problem in worldwide and horizontal transmission of bacterial organisms to cause a high mortality rate increased. Hand washing with soap and water can prevent a significant proportion of childhood diarrhoea and respiratory infections, the two main global causes of child mortality.  Objectives: The objectives were to assess the existing level of knowledge and practice of school going children on hand washing, to find out the correlation between level of knowledge and practice on hand washing among school going children and to find out the association between level of knowledge and practices of school going children on hand washing with their selected demographic variables. Methods: A quantitative evaluative approach with descriptive research design was adopted. 50 school going children were selected by the purposive sampling technique. Results:  The collected data was tabulated and analyzed. Descriptive and inferential statistics were used. In the level of knowledge majority of the school going children (52%) had inadequate knowledge, 28% of them were had moderately adequate knowledge and only 20% of them had adequate knowledge. The mean knowledge score on hand washing was 10.4 and the standard deviation was 4.31. The mean practice score on hand washing was 21.52 and the standard deviation was 7.4. Conclusion: The study results shows that most of the school children were having inadequate knowledge and less desirable practices of hand washing. A structured teaching program on hand washing is very important for incorporating the knowledge among school children.

Natural lighting is an important factor that affects the comfort of building users. Natural lighting in a room requires a window area of ​​at least 1/6 of the floor area. This study was conducted to obtain the distribution of Daylight Factor (DF) as a natural lighting factor during the day in the room, based on the shift in the position of the window on the wall. The distribution of lighting entering the depth of the room through window openings is a tool to compare the best window position in the spread of illumination with DF calculations based on Sky Component (SC). Shifting the window position will be analyzed by Standard Deviation (S) and Mean (μ) based on the DF distribution. Optimizations of the DF distribution on the window position shifts if it has the largest DF mean value and the smallest DF variant value. The results of the study in a simple room showed that the optimal DF distribution was at the window position in the middle and the mean value was 2.59%. The relationship of shifting window position and DF distribution can be useful for architects to determine the function of a room in architectural design.

The role of institutional ownership in the financial markets became very important. However, until today there is no consensus among researchers about the influence of institutional ownership on the characteristic of stock market. Therefore, researchers are motivated to conduct further research the influence of institutional ownership on the characteristic of stock market. The research conducted at the Indonesian Stock Exchange with traded spread and adverse selection costs as dependent variable and institutional ownership as independent variable. In addition to institutional ownership, also used standard deviation of common stock price and trading volume as a control variable to clarify the relationship of institutional ownership on the characteristic of stock market. The study was conducted on 120 firms with observations in the period 2010-2011. All the required data obtained from the Indonesian Capital Market Directory. The results showed that: First, institutional ownership has a negative and significant effect on traded spread. Second, the variability of traded spread is able to be explained by the variability of institutional ownership, standard deviation of the stock price, and trading volume 24.8 percent. Third, institutional ownership has a negative and significant effect on adverse selection costs. Fourth, the variability of adverse selection costs is able to be explained by the variability of institutional ownership, standard deviation of the stock price, and trading volume 26.2 percent. Fifth, the relationship between institutional ownership to traded spread and adverse selection cost before and after entering the control variables remain negative and significant.

PurposeThis study aims to investigate the relationship between risks and the expected return of financial investment because the relationship between them is negative; if the investors agree to the higher level of risk, they have the greater the expected return; therefore, investors always require a degree of proportionality between the risks and returns.Design/methodology/approachThis study applied the standard deviation, variance, coefficient of variation methods and matrix function to measure risks. Besides, the dataset is a return on equity ROE, which is collected in three companies at time series from 2005 to 2020.FindingsWhen the variance or the standard deviation is higher, the return on the securities is higher, but the securities are a higher risk and vice versa. The results showed risk levels of stocks that are 2.509%, 0.367%, 3.666% and the corresponding return mean of 38.68%, 23.99% and 14.02%.Originality/valueThe results support the portfolio management policy appropriately. This study identifies issues for managers, investors and readers to consider: have a comprehensive solution among microcosmic policies, finance policy, investment policy and other policies to control and balance the relationship between risks and returns; have appropriate policies to regulate funds to stimulate investment in the long term.
