The method used in this research is quantitative, namely the data obtained in the form of numbers and the analysis emphasizes numerical processing with statistics. The approach used in this research is correlational which aims to see the effect of the implementation of school-based management on the quality of education. The results obtained from this study state that there is a positive and close influence between the implementation of school-based management (SBM) on the quality of education at SDIT Al-Haraki Depok City which is indicated by the correlation coefficient value r = 0.464, it can be obtained the determination R2 = 0.215, which means that the implementation of school-based management (SBM) has contributed 21.5% to improving the quality of education at SDIT Al-Haraki.

Testing the randomness of shares in color visual cryptography

The concept of black-and-white visual cryptography with two truly random shares, previously applied to color images, was improved by mixing the contents of the segments of each coding image and by randomly changing a specified number of black pixels into color ones. This was done in such a way that the changes of the contents of the decoded image were as small as possible. These modifications made the numbers of color pixels in the shares close to balanced, which potentially made it possible for the shares to be truly random. The true randomness was understood as that the data pass the suitably designed randomness tests. The randomness of the shares was tested with the NIST randomness tests. Part of the tests passed successfully, while some failed. The target of coding a color image in truly random shares was approached, but not yet reached. In visual cryptography, the decoding with the unarmed human eye is of primary importance, but besides this, simple numerical processing of the decoded image makes it possible to greatly improve the quality of the reconstructed image, so that it becomes close to that of the dithered original image.

Non-numerical strategies used by bees to solve numerical cognition tasks

We examined how bees solve a visual discrimination task with stimuli commonly used in numerical cognition studies. Bees performed well on the task, but additional tests showed that they had learned continuous (non-numerical) cues. A network model using biologically plausible visual feature filtering and a simple associative rule was capable of learning the task using only continuous cues inherent in the training stimuli, with no numerical processing. This model was also able to reproduce behaviours that have been considered in other studies indicative of numerical cognition. Our results support the idea that a sense of magnitude may be more primitive and basic than a sense of number. Our findings highlight how problematic inadvertent continuous cues can be for studies of numerical cognition. This remains a deep issue within the field that requires increased vigilance and cleverness from the experimenter. We suggest ways of better assessing numerical cognition in non-speaking animals, including assessing the use of all alternative cues in one test, using cross-modal cues, analysing behavioural responses to detect underlying strategies, and finding the neural substrate.

The relationship between the height dimension and numerical processing

It is well documented that the ability to perceive numbers depends on perception of size. However, size consists of two different dimensions: height and width. In previous size-congruency experiments, the changes in the size dimension were confounded by changes in both the height and width dimensions. Hence, it is not clear if two digits that are equal in size but with different width and height produce a congruency effect and if so, which dimension (height or width) will be associated with quantity more prominently. In fact, different theories might predict different outcomes for the association of height versus width with numbers. To resolve this issue, this study included two experiments in which two equal-size digits that differed from each other in the height and width dimensions were presented and participants were asked to decide which digit is numerically larger. The results revealed a novel congruency effect in which larger numbers are associated more prominently with the height dimension when compared with the width dimension. This effect has important implications for understanding the relationship between number processing and the spatial perception system.
