Helping others but Hurting Yourself? The underlying mechanism linking helping behavior to task performance.

Helping behavior positively influences organizational effectiveness, which is why the importance of this behavior is highlighted in Chinese enterprises, and employees are encouraged to engage in it. However, from an actor-centric perspective, helping behavior is not always beneficial. In this paper, cognitive-affective personality system theory is applied to link helping behavior to task performance, thus enhancing the understanding of the effects of helping behavior.

Anti-hyperlipidemia on rats in vivo and new compounds from the seeds of Psoralea corylifolia.

In this study, it was confirmed at first time that the crude extracts of Psoralea corylifolia seeds (PCE34) can reduce serum lipids (AST, ALT, TG, TC, LDL, ALP, ACP and LDH), body weight and serum sugar, increase HDL and serum insulin in hyperlipidemic wistar rat induced by high-fat diet in vivo. Furthermore, eight new chalcones 1-8, one new flavanone 12, one new coumarin 14, three new meroterpenes 15-17 and one new bakuchiol 20 together with seven known compounds (9-11, 13, 18-19 and 21) were isolated from the PCE34. Their structures were elucidated based on analyses of their spectroscopic (UV, CD, NMR and HREIMS) data.

Hydrological connectivity dynamics of tidal flat systems impacted by severe reclamation in the Yellow River Delta.

River deltas contain complex self-organizing channel networks that continuously exchange fluxes of water, matter, energy, and information with their surroundings. The connectivity of these exchange processes plays a crucial role in controlling the evolution and dynamic stability of river deltas. However, connectivity patterns related to tidal channel networks have rarely been studied, especially in the Yellow River Delta (YRD), which is impacted by severe reclamation.

A model to evaluate spatiotemporal variations of hydrological connectivity on a basin-scale complex river network with intensive human activity.

In recent decades, rivers have been among the most gravely disturbed ecosystems due to intense anthropogenic impacts. Accurate spatial evaluation of river network connectivity is necessary for providing an improved empirical basis for management, conservation, and restoration initiatives. In this study, we focused on the stream continuity-oriented hydrological connectivity of the river network ecosystem.

River network connectivity and fish diversity.

Frequent and severe disruptions of natural river flows associated with human activities significantly alter hydrological connectivity in large river networks, with deleterious effects on fish diversity. Understanding the relationship between fish diversity and river network connectivity is fundamental to ensuring species persistence, ecosystem integrity, and human well-being. Here, we provide a review of the mechanisms by which river network connectivity (RNC) affects fish diversity.

A novel inhibitory kinetic fluorimetric method for the determination of trace methomyl in environmental samples.

A novel inhibitory kinetic fluorimetric method for the determination of trace methomyl was proposed. It was shown that the Fenton reagent oxidized rhodamine B in acid medium which enabled the fluorescence quenching of the latter. The presence of trace methomyl clearly inhibited the reaction.
