The advent of the digital age has profoundly changed consumers’mindsets and habits.The rapid development of e-commerce and the widespread use of mobile applications have created enormous demand for individual recommendation systems based on mass data.This system not only increases the convenience of purchases and conversions but also alters the purchasing behavior of consumers,leading them to make choices subconsciously.Potential risks associated with large-scale data sharing and usage have heightened consumer concerns regarding privacy,thereby weakening the foundational trust in platforms and deterring them from shopping.Additionally,the rapid growth of e-commerce in the digital age,coupled with changing market circumstances,has intensified psychological pressure on consumers,making their decision-making processes more complex and difficult.Furthermore,the program will explore issues related to improving customer experience,developing individual marketing strategies,and designing customer loyalty plans.It will also address questions of privacy in a digital environment,the dilemmas of excessive or disruptive consumption behavior,and the complexity and diversity of consumer behavior in the face of digital change.The objective of this study is to develop a fear study that will enable a better understanding of the impact of online shopping on consumer behavior and provide a strategic guide for retailers to meet the challenges and opportunities presented by the digital age. 展开更多

BACKGROUND Although the specific pathogenesis of preterm birth(PTB)has not been thoroughly clarified,it is known to be related to various factors,such as pregnancy complications,maternal socioeconomic factors,lifestyle habits,reproductive history,environmental and psychological factors,prenatal care,and nutritional status.PTB has serious implications for newborns and families and is associated with high mortality and complications.Therefore,the prediction of PTB risk can facilitate early intervention and reduce its resultant adverse consequences.AIM To analyze the risk factors for PTB to establish a PTB risk prediction model and to assess postpartum anxiety and depression in mothers.METHODS A retrospective analysis of 648 consecutive parturients who delivered at Shenzhen Bao’an District Songgang People’s Hospital between January 2019 and January 2022 was performed.According to the diagnostic criteria for premature infants,the parturients were divided into a PTB group(n=60)and a full-term(FT)group(n=588).Puerperae were assessed by the Self-rating Anxiety Scale(SAS)and Self rating Depression Scale(SDS),based on which the mothers with anxiety and depression symptoms were screened for further analysis.The factors affecting PTB were analyzed by univariate analysis,and the related risk factors were identified by logistic regression.RESULTS According to univariate analysis,the PTB group was older than the FT group,with a smaller weight change and greater proportions of women who underwent artificial insemination and had gestational diabetes mellitus(P<0.05).In addition,greater proportions of women with reproductive tract infections and greater white blood cell(WBC)counts(P<0.05),shorter cervical lengths in the second trimester and lower neutrophil percentages(P<0.001)were detected in the PTB group than in the FT group.The PTB group exhibited higher postpartum SAS and SDS scores than did the FT group(P<0.0001),with a higher number of mothers experiencing anxiety and depression(P<0.001).Multivariate logistic regression analysis revealed that a greater maternal weight change,the presence of gestational diabetes mellitus,a shorter cervical length in the second trimester,a greater WBC count,and the presence of maternal anxiety and depression were risk factors for PTB(P<0.01).Moreover,the risk score of the FT group was lower than that of the PTB group,and the area under the curve of the risk score for predicting PTB was greater than 0.9.CONCLUSION This study highlights the complex interplay between postpartum anxiety and PTB,where maternal anxiety may be a potential risk factor for PTB,with PTB potentially increasing the incidence of postpartum anxiety in mothers.In addition,a greater maternal weight change,the presence of gestational diabetes mellitus,a shorter cervical length,a greater WBC count,and postpartum anxiety and depression were identified as risk factors for PTB. 展开更多

BACKGROUND The working environment of submarine crews is also very special.They are in a closed,high-temperature,high-noise,high-vibration and narrow working and living space for a long time,and they suffer from physical discomfort caused by seasickness,which will affect the mental health of officers and soldiers.American psychologists have achieved positive results in psychological resilience training for officers and soldiers from the perspective of positive psychology.At present,there are few reports on the correlation between psychological resilience in the field of domestic research on submarine crew psychology,and it is necessary to conduct further research.METHODS A total of 121 soldiers working in a confined space of a large ship were randomly divided into an experimental group and a control group.The 50 soldiers in the experimental group were given a training course intervention,while the 71 soldiers in the control group did not receive any intervention measures.The Pittsburgh Sleep Quality Index,Psychological Resilience Scale,military Psycho-logical Stress Self-Assessment Questionnaire,and General Self-Efficacy Scale scores were compared before and 6 months after the intervention.RESULTS Under the positive psychological control intervention,except for sleep efficiency(P=0.05),the difference between the remaining dimensions of the Pittsburgh Sleep Quality Index scores and the total scores of the experimental group compared with the control group was statistically significant(P<0.05);the assessment of the psychological condition showed that,in addition to the Psychological Stress Self-assessment Questionnaire for Military Personnel scores(P=0.05),the scores of the Mental Toughness Scale(Dispositional Resilience Scale Resilience II)in the experimental group,General Self-Efficacy Scale scores were statistically significant(P<0.05)compared to pre-intervention.CONCLUSION Positive psychological intervention and control can improve the sleep state and psychological state of officers and soldiers working in confined space at sea. 展开更多

In the last two decades, China has become one of the areas that have the greatest potential in industrial production, thus it has ranked second only to USA in the flow of international capital. By the end of 1998, the real value of FDI (Foreign Direct Investment) in China has utilized has added up to $268.1 billion. The big flow of FDI has not only promoted the development of social economy, but also worsened the existing regional difference by choosing spatial location. Under this circumstance, China’s economy faces new restrictions and opportunities while adjusting its regional structure and industrial structure. So it is more and more important for us how to seize the opportunity, to seek the regularity of FDI in choosing location from the aspect of space, to set up relevant strategy to direct FDI at inland regions (areas deficient of capital), and to make appropriate policies, esp. the industrial and regional policies so as for FDI to exert positive influence and avoid negative influence on China and its regional economy and society. Based on the latest domestic and overseas materials and data of the FDI in China, combining with the investigation of the enterprises, this paper has systematically revealed the progress of development of the FDI in China and the developing conditions of the main enterprises directly invested by foreign capital since the reform and opening-up in China. The characters of FDI such as spatial concentration, transference as time goes on, change of the technical content and up-gradation of industrial structure and their forming mechanism have been studied. Then the basic conclusions have been made as follows. Firstly, FDI has been highly concentrated in space. But as time goes by, it has been transferring from coastal regions to inland ones, from big cities to their surrounding districts, and the degree of concentration is decreasing. Secondly, the technical content of the invested projects has gradually increased and the up-gradation of the industrial structure is obvious. Thirdly, the regional choice of the FDI in China is mainly affected by labor and other productive factors. The relative change of the cost of productive factors in different regions since the reform and opening-up is one of the main factors that have caused the spatial transference of the FDI in China. Fourthly, as people’s income increases and the accumulation of the capacity of the technique and labor advances, FDI whose aim is to get more market has increased and tended to transfer from coastal regions to inland ones. Fifthly, the changes of the industrial structure of the main areas and countries who have directly invested in China and the changes of inter-regional industries and regional policies in China are also the important factors that affect the industries directly invested by foreign capital and their spatial transference. 展开更多

Objective: To discuss the expression of long noncoding RNA TUG1 (IneRNA-TUG1) in gastric carcinoma (GC) and its effects on the transferring and invading capacity of gastric carcinoma cells. Methods: Forty cases of carcinoma tissue and para-carcinoma tissue were selected from GC patients who underwent surgical removal in Zhejiang Provincial Hospital of Chinese Traditional Medicine and Wenzhou Central Hospital from January, 2013 to December, 2014; the expressing level of IncRNA-TUG I in GC and para-C tissues was detected by applying the qRT-PCR technique. The correlation between IncRNA-TUG1 expression and patients' clinical data was classified and analyzed. SGC-7901 cells were transfected using IncRNA-TUG1 specific siRNA. Changes of the transferring and invading capacity of siRNA-transfected SGC-7901 cells were scratch-tested and transwell-detected. qRT-PCR was applied to detect the expression level of microRNA-144 after IncRNA-TUG1 was silenced. Changes of c-Met mRNA and protein expressions was detected by qRT-PCR and western -blot test. Results: The expression level of lneRNA-TUG1 in GC tissue was significant higher than that in para-C tissue (P<0.05) and the high expression level of IncRNA-TUG1 in GC tissue was significantly correlated with tumor lymph nodes metastasis and advance TNM phasing (/'<0.05). The transferring and invading capacity of SGC-7901 cells was highly inhibited after being transfected by IncRNA-TUG1 specific siRNA (P<0.05). The results of qRT-PCR and western -blot proved that the expression of microRNA-144 was significantly boosted and the expression level of c-Met mRNA and protein was inhibited after IncRNA-TUG1 was silenced (P<0.05). Conclusions: IncRNA-TUG1 shows an up -regulated expression in GC tissue and that bears a correlation with clinicopathological features of malignant tumor. IncRNATUGI can promote the transferring and invading capacity of GC by inhibiting the pathway of microRNA-144/c-Met. 展开更多

Concept of city square was introduced and believed as an important component of urban landscape and also a major space for urban residents' activities. Beauty of city square lies in the interaction between environment and social behaviors. By introducing the two-way interaction between city square and users, behavior psychology was proposed as the foundation of environment design of plaza. As more and more attention is given to humancentered design of outdoor spaces, environment psychology has gradually been more applied in the design of various urban landscape spaces. In view of problems in the present square design, relevant theories of environment psychology were introduced to analyze psychological needs and behavior characteristics of people in outdoor spaces, and techniques for human- centered designs of city square explored to build public spaces for city dwellers. 展开更多

This study investigates anxiety in foreign language learning from a positive psychology perspective,and in doing so,it considers some of the ways in which anxiety can interact with other aspects of language learner psychology to contribute to improved learning outcomes and improved learner well-being.The paper reports on a small-scale mixed-method study of English learners at a university in northern Japan.It shows how for many learners some of the most anxiety-provoking episodes were also the most rewarding and enjoyable,suggesting a need to reconsider simplistic accounts that present anxiety as an impediment to successful language learning.This is done by shifting to a positive psychology perspective.The paper concludes with a tentative model of how anxiety,when reframed as tension,can function as a core component of a more productive language learning experience. 展开更多

The stress transfer mechanism of steel fibre reinforced concrete is studied. The solutions for the stress and displacement were regarded as the superposition of ' the elementary solutions' and ' the improved solutions'. The elementary solutions were found by using two-dimensional elastic theory and the improved solutions were found by using the Love displacement function method. The calculated results indicate that the solutions possess good convergence. By comparing the three-dimensional solutions with the shear-lag solutions, evident difference may be found. 展开更多

Hg vertical transference in soil water system was studied by analyzing Hg vertical distribution in soil column after adding Hg and one of the two leacheates, deionized water or acid rain, into soil column. The results indicated that Hg was hardly transferable in purple soil. About 86%~88% of the total soil Hg was distributed in the top layer (0~2 cm) and no Hg was detected in the leakage when the purple soil column was leached by deionized water and simulated acid rain. But Hg was more movable in yellow soil with only about 20%~22% of the total soil Hg distributed in the top layer (0~2 cm), and about 17%~25% washed out from the soil column by deionized water and simulated acid rain. Increment in soil bulk density could reduce Hg leaching, thus the more the Hg kept in soil, the less the Hg leached into underground water. Deionized water and acid rain almost played the same role in leaching Hg. Bentonite was most efficient in preventing Hg from vertical transferring in the soil column. 展开更多

Some extraditional types—black rock series types of platinum group element (PGE), gold and silver mineralization occurrences were found in the Lower Cambrian in Guizhou and Hunan provinces of southwest China where PGE concentration reaches more than 800×10 -6. Sea floor hydrothermal fluid eruption was suggested to have been the main origin of the ore-forming materials. The whole process from the sedimentation to the redistribution of the ore-forming elements occurred on the conditions of intermediate to weak alkaline, weak reduction to weak oxidation. The temperature for the sedimentation and redistribution of the ore-forming elements was lower than 210 ℃. At such a low temperature, inert elements such as PGE, Au and Ag could quite easily be remobilized. 展开更多
