Research on the Marketing Strategy of Online Education - Taking New Oriental as an Example

In recent years,with the development of society and the progress of science and technology,online learning has penetrated into people’s daily life,and people’s demand for high-quality curriculum products is more and more strong.From a macro perspective,the continuous growth of national financial investment in education,the continuous upgrading of China’s consumption structure,the development of 5G technology and the popularization of AI intelligence make online teaching less limited.The online education industry is showing an explosive growth trend.More and more online education institutions are listed for financing,and the market value is soaring.However,in 2019,except for GSX,the latest online learning platforms such as New Oriental,Speak English Fluently and Sunlands,have been in a state of loss.Most of these agencies seize the market by increasing advertising investment,but at the same time,they also bring huge marketing costs,which affect the financial performance of the company.With the enhancement of Matthew effect,largescale educational institutions occupy a large market through free classes and low-price classes,while small and medium-sized institutions with weak capital strength are often unable to afford high sales costs,facing the risk of capital chain rupture.Taking new Oriental online as an example,this paper analyzes the problems existing in the marketing strategies of online education institutions.It also puts forward suggestions on four aspects,which are target market,differentiated value,marketing mix and marketing mode,so as to make sure that online education institutions can control marketing expenses and achieve profits by improving course quality,expanding marketing channels and implementing precise positioning.

Enhancing the electrochemical performance of Na metal anodes via local eutectic melting in porous Al-Cu alloy hosts

Sodium(Na)metal batteries(SMBs)have emerged as promising alternatives to lithium metal batteries for large-scale energy storage applications,owing to their cost-effectiveness,abundance,and favorable redox potential.However,the practical implementation of SMBs faces several challenges associated with the Na metal anode,including the formation of dendrites,low Coulombic efficiency,and capacity fading.Here,we propose a novel approach to enhance the electrochemical performance of Na metal anodes through a porous Al-Cu alloy host(PAC)fabricated by a local eutectic melting engineering.The local eutectic melting facilitates the development of a conductive network,offering mechanical support,and the porous structure provides abundant channels for the diffusion of Na ions and accommodates volume fluctuations in the Na metal during charge–discharge cycling.Moreover,the PAC exhibits a high average Coulombic efficiency of 99.8%at 1 mA·cm^(−2)for 1 mAh·cm^(−2)and a low voltage polarization of 19 mV during 500 cycles.This study provides valuable insight into the design and fabrication of highperformance Na metal anodes,which hold significant promise for the advancements of next-generation energy storage systems.

Reversible magnetism transition at ferroelectric oxide heterointerface

Oxide heterointerface is a platform to create unprecedented two-dimensional electron gas, superconductivity and ferromagnetism, arising from a polar discontinuity at the interface. In particular, the ability to tune these intriguing effects paves a way to elucidate their fundamental physics and to develop novel electronic/magnetic devices. In this work, we report for the first time that a ferroelectric polarization screening at SrTiO_(3)/PbTiO_(3) interface is able to drive an electronic construction of Ti atom, giving rise to room-temperature ferromagnetism. Surprisingly, such ferromagnetism can be switched to antiferromagnetism by applying a magnetic field, which is reversible. A coupling of itinerant electrons with local moments at interfacial Ti3d orbital was proposed to explain the magnetism. The localization of the itinerant electrons under a magnetic field is responsible for the suppression of magnetism. These findings provide new insights into interfacial magnetism and their control by magnetic field relevant interfacial electrons promising for device applications.

Lateral Hypothalamus Calcium/Calmodulin-Dependent Protein Kinase IIα Neurons Encode Novelty-Seeking Signals to Promote Predatory Eating

Predatory hunting is an innate appetite-driven and evolutionarily conserved behavior essential for animal survival, integrating sequential behaviors including searching, pursuit, attack, retrieval, and ultimately consumption. Nevertheless, neural circuits underlying hunting behavior with different features remain largely unexplored. Here, we deciphered a novel function of lateral hypothalamus (LH) calcium/calmodulin-dependent protein kinase II α (CaMKIIα^(+)) neurons in hunting behavior and uncovered upstream/downstream circuit basis. LH CaMKIIα^(+) neurons bidirectionally modulate novelty-seeking behavior, predatory attack, and eating in hunting behavior. LH CaMKIIα^(+) neurons integrate hunting-related novelty-seeking information from the medial preoptic area (MPOA) and project to the ventral periaqueductal gray (vPAG) to promote predatory eating. Our results demonstrate that LH CaMKIIα^(+) neurons are the key hub that integrate MPOA-conveyed novelty-seeking signals and encode predatory eating in hunting behavior, which enriched the neuronal substrate of hunting behavior.
