Balanced time perspective and aggression in left-behind children: The mediating role of self-esteem.

Left-behind children refer to children who have been separated from their parents for a long period of time because one or both parents have gone to work in cities and towns, and who stay in their hometowns or board with relatives in rural China. This study investigated the association between time perspective and aggression among left-behind children and examined the potential mediating role of self-esteem. The initial cross-sectional study (Study 1) involved a sample of 549 middle school students (M = 13.

The Trade-Off between Dechlorination and Polymerization for Facile Fabrication of Electronic Grade Epoxidized Cardol.

The dechlorination of epoxidized Cardol (E-Cardol), which is a high-performance and sustainable adhesive and packaging material for electronics, remains challenging. The previous work proposed a new alcohol-sodium refining method to efficiently remove the chlorine of E-Cardol. However, this method is strongly limited by the trade-off between the dechlorination efficiency and its polymerization side effect, which leads to the viscosity as well as the epoxy equivalent increase of E-Cardol.

Bias-drift insensitive full-field frequency response characterization of a thin-film lithium niobate-based intensity modulator.

We propose a rapid and precise scheme for characterizing the full-field frequency response of a thin-film lithium niobate-based intensity modulator (TFLN-IM) via a specially designed multi-tone microwave signal. Our proposed scheme remains insensitive to the bias-drift of IM. Experimental verification is implemented with a self-packaged TFLN-IM with a 3 dB bandwidth of 30 GHz.

Direct Work Function Measurement Using in-situ Ambient Pressure X-ray Photoemission Spectroscopy and Its Application on Copper Oxidation Process.

The work function (WF) measurement plays a critical role in engineering energy materials and energy devices. However, the ultra-high vacuum (UHV) environments of photoemission method limit the practical application for absolute work function measurements of materials, especially under complex working conditions. To understand the energy level of materials under complex chemical environments, the in-situ measurements of work function is necessary in complex metal/semiconductor system for various application.

CAC: Confidence-Aware Co-Training for Weakly Supervised Crack Segmentation.

Automatic crack segmentation plays an essential role in maintaining the structural health of buildings and infrastructure. Despite the success in fully supervised crack segmentation, the costly pixel-level annotation restricts its application, leading to increased exploration in weakly supervised crack segmentation (WSCS). However, WSCS methods inevitably bring in noisy pseudo-labels, which results in large fluctuations.

In this longitudinal study, we tested the reciprocal impacts of self-efficacy and coping styles, taking into account the role of future self-continuity (FSC) in these effects.

Another way to measure balanced time perspective: Development and validation of the Time Perspective Inventory.

The existing scales for measuring balanced time perspective (BTP) have limitations, such as poor-fitting structures or a complex calculation method. Based on previous studies, we conceptualize BTP as an individual's overall positive outlook on the past and future and mindfully living in the present. The present study aimed to develop the Time Perspective Inventory (TPI) for Chinese adults, determine its psychometric properties, and examine a simple calculation method for generating a score to represent BTP.
