Abstract:

AbstractEffect size indices are useful tools in study design and reporting because they are unitless measures of association strength that do not depend on sample size. Existing effect size indices are developed for particular parametric models or population parameters. Here, we propose a robust effect size index based on M-estimators. This approach yields an index that is very generalizable because it is unitless across a wide range of models. We demonstrate that the new index is a function of Cohen’s d, $$R^2$$ R 2 , and standardized log odds ratio when each of the parametric models is correctly specified. We show that existing effect size estimators are biased when the parametric models are incorrect (e.g., under unknown heteroskedasticity). We provide simple formulas to compute power and sample size and use simulations to assess the bias and standard error of the effect size estimator in finite samples. Because the new index is invariant across models, it has the potential to make communication and comprehension of effect size uniform across the behavioral sciences.

Abstract:

In an effort to increase the liquidity and accessibility to the investors, National Stock Exchange of India (NSE) had reduced contract size of its Nifty index futures two times from 200 to 100 and, subsequently, to 50 units. How does this change in contract size of index futures impact the informed and hedge based trading, thereby contributing to the twin objectives of price discovery and risk management, respectively? VAR model is applied to daily return volatility, volume and open interest to study the impact. Significant feedback relationship between volume and volatility following the reduction in contract size establishes the informational trading and price discovery. However, no causality from volatility to open interest implies contract size is not a determinant of hedging. But significant causality from open interest to volatility is establishing the non-informational and liquidity trading. So stock exchanges should consider the appropriate lot size before going for introducing new futures contract

Abstract:

The present study investigated actual body size as measured by the Body Mass Index in comparison to self-reported body size among diverse college student population. The study was conducted at a large public university in the western United States. Of the random sample of 15,000 enrolled students selected to receive an electronic survey, a total of 1,798 students elected to participate. Normalizing of overweight and obesity was found among study participants. The results from this survey indicate that, despite the fact that the majority of participants engaged in weight management methods, all gender and ethnic groups underreported instances of overweight and obesity, as well as discrepancies between perceived body image and actual body size. Implications for health promotion and future research are highlighted.

Abstract:

Objective: to use sonography in a follow-up study aimed at assessing the size of the thymus in healthy infants, and to search for a possible relation to clinical variables, breast-feeding status, and illness. Material and Methods: Forty-seven healthy infants were examined as neonates and re-examined at 4 months of age. Thirty-seven of the infants were also re-examined at 8,10, and 12 months of age. the thymus size was measured with the sonographic thymic index used as a volume estimate. the correlations between the thymic index and the sex, weight, length, illness, and breast-feeding status of the infants were analysed. Results: at birth the median thymic index was 12 (range 4–29). at 4 months the median thymic index was 28 (range 12–83). the thymic index was positively correlated to the body length of the infant and to its breast-feeding status (p<0.0001). at 8 months the median thymic index was 29 (range 6–55) and most of the variation could be explained by the length of the infant (p=0.0018, r=0.50). at 10 months the median thymic value had decreased to 19 (range 9–49), and at 12 months to 17 (range 7–53). Infants exclusively breast-fed during the first 4 months of their lives had a larger thymic index at 10 months than formula-fed infants (p=0.0024). Infants with fever episodes from 10 to 12 months had a smaller thymic index at 12 months (p=0.0241). Conclusion: the thymus size in healthy infants increases from birth to 4 and 8 months of age and then decreases. Most of the individual variation can be explained by breast-feeding status and body size, and to a lesser extent by illness. We propose statistical models by which the normal variation/distribution of the thymic size can be estimated in infants up to one year of age.

Abstract:

Site index is difficult to implement and interpret in multispecies, multiple-aged stands, and its relationship to site factors is obscure. Using data from the USDA forest inventory and analysis (FIA) for the Lake States, we developed log-log relationships between mean tree size and stand density for five cover types. Fits were good, with r2 from 0.96 to 0.98 and slopes from −0.948 to −0.995. We define an alternative index of site quality, the relative stocking index (RSI), as the ratio of a stand's measured density to that predicted using the log–log relationship for its cover type (the norm). We divided the range of RSI into three classes for each type (<0.9 of norm, >0.91 but <1.1 of norm, and >1.1 of norm). Based on analyses of the 1977 and 1990 FIA data from Minnesota, class assignments for individual stands remained constant over that 13-year period. Relationships between site factors and either RSI classes or analogous classes based on site index were examined in a subset of 169 stands. Temperature, precipitation, silt content of surface soil, and calculated annual water deficit all differed significantly among RSI classes, but not among site-index classes. The RSI is easy to apply, robust (resistant to change), and related to site factors. It merits additional examination as an index of site quality, especially in heterogenous stands.

Abstract:

Compliance criteria for the sample size n = 3 have a lot of disadvantages [5,6,7] and they can affect the reduction of quality of produced concrete and, consequently, they can cause too much risk of the recipient (the investor) side. Therefore, the effect of the sample size on the defined quality index of produced concrete has been evaluated. The effect of the sample size and standard deviation on the reliability index of reinforced concrete structures has also been determined.The impact analysis of compliance criteria on the reliability index of reinforced concrete structures was conducted for a compression column. The obtained values of the reliability index results confirm the correctness of the quality index formula and concrete quality proposed in method of defining.

Abstract:

Currently, the soil-aggregate mixture has been widely used in some large-scale site preparation projects, compaction characteristics has been pay more attention by many engineers and researchers. However, systematic research is insufficient on how to choose the filler. Moreover, some industry regulations are different on the requirements about filler. This paper relies on a certain big site preparation projects, discussing statistical characteristics and correlation on the maximal grain size, contents of the coarse grain, gradation and other parameters of soil-aggregate mixture. The results show that the maximal and the median grain size have small discreteness and normal distribution, indicating site filler is easy to reach the requirement; The coefficient of curvature, coefficient of nonuniformity and the coarse grain content have large discreteness, and dont obey normal distribution, indicating the filler has large variability. The median grain size is highly relevant to the coarse grain content; the maximal grain size isnt relevant to the coefficient of nonuniformity, the coefficient of curvature and the coarse grain content. According to the results of correlation analysis, we suggest that the importance order follow by coarse grain content, the maximum grain size and gradation for the control parameters of filler. This research may be significant to other similar projects.

Abstract:

Sovereign wealth funds accumulate the largest resources to bridge the financial gap under the Sustainable Development Goals. The basic mechanism for accelerating sustainability progress is the effort of sovereign wealth funds to incorporate environmental, social, governance and ethical criteria and targets of these Goals disclosed in their sustainability reports. This study aims to develop a methodology for assessing the Sustainability Transparency Index in a sample of sovereign wealth funds, as well as to investigate how this transparency is influenced by the size of funds’ assets and sustainability progress with a cross-regional comparison. Five groups of sustainability disclosure metrics, such as the main pillars of novel Sustainability Transparency Index, were tested and analyzed for 91 funds using binary variables and normalization method. Three hypotheses regarding the statistical association of funds’ sustainability transparency index with the size of the funds’ assets, countries’ sustainability progress, and the region of a fund were checked for 87 funds using multiple regression. The overall results of the Sustainability Transparency Index show an insufficient level of funds’ transparency. Sustainability disclosure in 57% of funds surveyed should be fully enhanced in terms of greater sustainability transparency. There is strong evidence of the correlation between the volume of funds’ assets and sustainability transparency as well as the leadership of European funds in a cross-regional comparative study. However, data on the progress of the country’s sustainability and the funds’ Sustainability Transparency Index are limited and can be used as evidence of the insufficient role of fund transparency in promoting sustainability.

Abstract:

There was elucidated the original approach to the evaluation of phytopopulation size structure. For its characteristics it was offered to use the special index - index diversity of size structure (ІDSS). There are presented methods and algorithm of its determination. There was demonstrated that index diversity of size structure can be used at populational studies of species that belong to the different living forms. Especially phanerophytes (Pinus sylvestris) and hamephytes (Ledum palustre). As to Pinus sylvestris and Ledum palustre with help of index diversity of size structure was objectively proved that its cohorts and ontogenetic groups that growth in composition of forest phytocenoses typical for Ukrainian Polissya are not characterized with high level diversity of size structure. The value of index diversity of size structure is mainly less than 20 %. In phytopopulation the specific and phytocenotic peculiarity is demonstrated by diversity of size structure and also by representation of plants of certain size classes.

Abstract:

Small-sided and conditioned games (SSGs) are pedagogical tools that help in soccer training, being used to solve tactical problems with the specific demands of the game. In this context, this study aimed to compare physical, physiological, and tactical responses in elite women’s soccer in SSGs with numerical equality (3-a-side) and superiority (3-a-side + 1) in the offensive phase. The sample consisted of 16 female athletes participating in official national competitions. Two consecutive days of data collection were conducted, and a 4 min duration series was carried out. The variables analysed were the total distance covered, the distance covered at different speeds, maximum heart rate (HRmáx), mean heart rate, the spatial exploration index, the stretching index, length, width, and LpWratio. The results showed an increase in distance covered at speeds of 7.20–14.29 km/h (m) (effect size: medium) and a decrease in HRmáx (effect size: small) in the numerical superiority. Regarding tactical response, there was a decrease in the spatial exploration index (effect size: large), length (effect size: medium), and stretching index (effect size: large) for games played in the numerical superiority. Thus, it was observed that SSGs with numerical superiority in women’s soccer suggest more clustered, less exploratory, and more positional behaviour of the athletes.

Abstract:

It is a well-known fact that the value of the Bond work index (wi) for a given ore varies along with the grinding size. In this study, a variability bysis is carried out with the Bond standard grindability tests on different critical metal ores (W, Ta), ranging from coarse grinding (rod mills) to fine grinding (ball mills). The relationship between wi and grinding size did not show a clear correlation, while the grindability index (gpr) and the grinding size showed a robust correlation, fitting in all cases to a quadratic curve with a very high regression coefficient. This result suggests that, when performing correlation studies among ore grindability and rock mechanics parameters, it is advised to use the grindability index instead of the Bond work index.
