Social media has been playing an important role in marketing strategy. As a part of social media, social networking sites (SNS) can be utilized by enterprises to create direct communication and good relationships with their customers. Therefore, enterprises using SNS have to select the right marketing content to enhance strong customer relationships, which lead to their behavior generating sustainable performance for enterprises. This research considered social media marketing activity (SMMA) and Customer Experience (CX) to measure the customer’s relationship quality, which can impact customer behavioral outcomes, which are purchase intention, loyalty intention, and participation intention. The 413 online questionnaire surveys were measured and analyzed using SmartPLS 3. The results show that SMMA and CX have a significant influence on the customer relationship quality, which also leads to a positive impact on customer behavioral outcomes. This research guides enterprises that SNS’s marketing content has to follow SMMA and CX dimensions to achieve the marketing objective and generate sustainable performance for enterprises.

With the warm/cold phases of the El Niño and Southern Oscillation (ENSO) as a background, the impacts of monthly variation in the Arctic Oscillation (AO) on the winter climate anomalies in East Asia are studied with the NCEP/DOE Reanalysis 2 data and the Chinese station data regarding temperature and rainfall. The combined effects of ENSO and the AO indicate that the winter climate anomalies are mainly influenced by the AO in northern China and the ENSO in southern China, when an El Niño couples with a negative AO month or a La Niña couples with a positive AO month. These climate anomalies in China are consistent with the mechanisms proposed in previous studies. However, most of China presents a different pattern of climate anomalies if an El Niño couples with a positive AO month or a La Niña couples with a negative AO month, with the exception of the temperature anomalies in northern China, which are still affected dominantly by the AO. Further analysis suggests that the causes are attributed to the differences in both the stratosphere-troposphere interaction and the extratropics-tropics interaction. In the former cases, zonal symmetric circulation prevails in the winter and the extratropics-tropics interaction is weakened. Thus, the influences of the ENSO and the AO on the East Asian climate mainly present linear combination effects. On the contrary, an annular mode of atmospheric circulation is not favored in the latter cases and the extratropics-tropics interaction is strong. Hence, the combined effects of the ENSO and the AO on the winter climate in East Asia present nonlinear characteristics.ENSO, AO, winter climate in East Asia, temperature and rainfall anomalies, stratosphere-troposphere interaction Citation:Chen W, Lan X Q, Wang L, et al.

This study aimed to explore the pattern of accumulation of some of main heavy metals in blood and various organs of rats after exposed to the atmospheric fine particulate matter (PM2.5). Rats were randomly divided into control and three treatment groups (tracheal perfusion with 10 mg/kg, 20 mg/kg and 40 mg/kg of PM2.5 suspension liquid, respectively). Whole blood and the lung, liver, kidney, and cerebral cortex were harvested after rats were treated and sacrificed. The used heavy metals were detected using inductively coupled plasma-mass spectrometry (ICP-MS) instrument. As results, Lead was increased in the liver, lung and cerebral cortex and the level of manganese was significantly elevated in the liver and cerebral cortex in PM2.5 treated rats. Besides, arsenic was prominently enriched both in cerebral cortex and in blood, and so did the aluminum in the cerebral cortex and the copper in the liver. However, cadmium, chromium and nickel have shown no difference between the control group and the three PM2.5 treated groups. Following the exposure of PM2.5, different heavy metals are preferentially accumulated in different body tissues.
