Achievement goal theory assumes that self-instrumental (mastery) achievement goals are associated with academic achievement, whereas social-instrumental (performance) goals are not. However, research on Asian students shows that both mastery and performance-approach goals are positively related to achievement; possibly because achievement motivation in Asian cultures is socially oriented and not individually oriented. The current study explored the structure of the social and individual achievement motivation orientations, and how these achievement orientations and achievement goals were related to achievement of Filipino university students. The results showed two dimensions of social-oriented achievement motivations-parent-oriented and teacher-oriented motivations-and two dimensions of individual-oriented achievement motivations-personal performance standards and personal goal choice. However, these achievement motivation orientations were not associated with achievement. Instead mastery and performance-approach goals were both positively associated with academic achievement, personal performance standards, and parent-oriented achievement motivation.

Purpose: This study aimed to initially test whether machine learning approaches could categorically predict two simple biological features, mouse age and mouse species, using the retinal segmentation metrics.
Methods: The retinal layer thickness data obtained from C57BL/6 and DBA/2J mice were processed for machine learning after segmenting mouse retinal SD-OCT scans. Twenty-two models were trained to predict the mouse groups.

We applied a classifier method to predict palladium catalysts for the formation of nonalternating polyketones via the copolymerization of CO and ethylene; current examples are limited to using phosphine sulfonate and diphosphazane monoxide supporting ligands. With the reported workflow, we discovered two new classes of palladium complexes capable of achieving the synthesis of nonalternating polyketones with a lower CO content than those made by known palladium catalysts. Our results show that we doubled the number of classes of palladium compounds that can catalyze the formation of this type of polymer.

Reverse flotation separation of muscovite from apatite using a dodecylpyridinium chloride (DPDC) ionic liquid as the collector was studied in this work. The microflotation results depicted that DPDC had a strong collecting for muscovite but had a slight collecting for apatite when using phosphoric acid as a depressant for apatite in a weakly acidic pH value pulp, artificial mixture mineral flotation showed that reverse flotation separation of muscovite from apatite can be effectively achieved in the reagent scheme of phosphoric acid/DPDC, and DPDC had a better separation performance in the muscovite/apatite system than DDA. The adsorption measurements indicated that the adsorption amount of DPDC on the apatite surface was less than that of DPDC on the muscovite surface, and the zeta potential results confirmed that a strong interaction occurred between DPDC and the muscovite surface, while an extremely weak interaction occurred between DPDC and the apatite surface in the presence of phosphoric acid at pH ∼ 5.

Hydrogen-substituted graphdiyne (HsGDY) is a two-dimensional material with an sp-sp carbon skeleton featuring a band gap and a porous structure that enhances ion diffusion. In previous reports, HsGDY growth was limited to metal substrates such as Cu, which then required transfer. Here, we developed a sandwich method that allows HsGDY to be grown directly on the target substrate.

The eyes are easily stimulated by external factors, which can cause inflammation. Anti-inflammatory drugs are usually used to inhibit the production of inflammatory factors. Many nonsteroidal anti-inflammatory drugs have been used for the eye, but due to the poor solubility of meloxicam, there are currently no marketed meloxicam preparations for the treatment of eye diseases.
