Mechanism of Tourists’Happiness in Traditional Village Tourism: A Perspective Grounded in Nostalgia and Cultural Attachment

In recent years,traditional villages have emerged as popular tourist destinations due to their distinctive resource value.Typically situated in remote and less developed areas,traditional villages boast primitive natural surroundings and rich historical and cultural heritage.These characteristics offer urban dwellers a temporary escape from the complexities of modern life,allowing them to experience physical and mental rejuvenation,mental relaxation,and overall happiness during their visit.By conducting a review of the existing literature concerning tourists’happiness in traditional villages,this study establishes a framework to understand tourists’happiness in traditional village tourism.Using the Qiangang ancient village in Conghua District,Guangzhou as a case study,the research examines the current state of rural characteristics,the establishment of cultural brands,and the promotion of the active utilization of ancient villages within the context of integrating culture,sports,tourism,and agriculture.Based on this analysis,the author proposes strategies to enhance tourists’happiness,including the preservation and development of rural characteristics,the promotion and preservation of local cultural attributes,and the collaborative advancement of culture,sports,tourism,and agriculture to engage key stakeholders actively.

Attachment Styles and Traumatic Responses: Exploring the Impact of Parental Interaction on Child Development and Coping Mechanisms

This article explores the intricate relationship between attachment styles formed during early childhood and the subsequent responses to traumatic events, particularly the death of a parent. Drawing on the theoretical framework of attachment theory and incorporating contemporary research, the paper discusses how parental interactions shape the neural circuitry of infants and children, influencing their ability to form secure or insecure attachments. These attachment styles, in turn, play a critical role in determining the child’s coping mechanisms when faced with trauma. This paper focuses on trying to understand how attachment theory is connected to the reaction to trauma with a highlight on the four major styles of attachments which are secure, anxious, avoidant, and disorganized to mention but a few, and how they influence stress and adversity in children. Attachment theory holds that human beings’ ability to form affectional bonds in infancy determines their patterns of relatedness across the life cycle. The type of attachment that is secure usually supports healthy adaptation and good coping mechanisms regardless of the trauma in the childhood of the child. While secure attachment mostly facilitates favorable trauma-related outcomes, anxious or avoidant attachment can exacerbate or alter the responses. The caregiving system that is avoidant attachment has implications of autonomous self-functioning which has features of suppression of the emotional response and poor search for emotional support during stress. From the principles of developmental psychology and trauma theory, the paper also focuses on the major significance of the child’s early caregivers’ interactions that define the resilience and vulnerability factor. This knowledge is therefore critical in designing specific interventions based on the improvement of coping behaviors and emotional regulatory systems of children who have been exposed to trauma. Finally, we have the synthesis of new knowledge about the role of secure attachment relationships as its fundamental element in shaping adaptive traumatization and psychological development. The article also delves into the physiological processes involved in emotional regulation and the role of cortisol in disrupting attachment. Finally, the implications of these findings for therapeutic interventions and the challenges of addressing prolonged grief and traumatic responses in clinical settings are considered.

Morphology prediction of dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate (TKX-50) crystal in different solvent systems using modified attachment energy model

In order to theoretically study the growth morphology of dihydroxylammonium 5,5’-bistetrazole-1,1’-dio late(TKX-50)crystal in different solvent systems,crystal–solvent models were established,and then molecular dynamics(MD)methods were adopted as a means to simulate particle motion.Modified attachment energy(MAE)model was employed to calculate the growth morphology of TKX-50.The simulation results demonstrate that COMPASS force field and RESP charge are suitable for molecular dynamics simulation of TKX-50.The morphologically dominant growth surfaces of TKX-50 in vacuum are(020),(011),(11–1),(100)and(120),respectively.In water(H_(2)O)and N,N-dimethylformamide(DMF)solvents,the(11–1)face is the largest in the habit face,the growth rate of(020)face becomes faster.With the increase of temperature,the aspect ratios of TKX-50 crystal in DMF solvent increase,and the areas of the(120)faces decrease.In ethylene glycol/H_(2)O mixed solvent system with volume ratio of 1/1,aspect ratio of TKX-50 is relatively small.In formic acid/H_(2)O mixed solvents with different volume ratios(1/4,1/3,1/2,1/1 and 2/1),aspect ratio of TKX-50 is relatively small when volume ratio is 1/2.

Cytokine changes and embryo attachment in mouse endometrial cells following treated with peripheral blood mononuclear cells(PBMCs)expressing ectopic hCG,and hCG-activated PBMCs

Objective:To compare the effect of human chorionic gonadotropin(hCG)-producing peripheral blood mononuclear cells(PBMCs)and PBMCs activated by hCG in vitro and expressions of related immune genes in mouse implantation.Methods:hCG-producing PBMCs(transfected PBMC)and PBMCs activated by hCG in vitro were introduced into isolated mouse endometrial cells,while cell cultures were divided into four groups:the control,PBMC,transfected,and activated PBMC groups.The expression of studied genes(IL-1β,IL-6,Lif,and Vegf)was evaluated and blastocyst attachment on the cocultured cells(isolated endometrial cells and PBMC cells)was monitored in all four groups.Results:Data showed that expression decreased in the PBMC group compared to the treated PBMC(transfected and activated PBMCs)and increased in transfected PBMC compared to the activated PBMC.Attachment and migration of blastocysts were dramatically enhanced in the transfected PBMC group compared to the activated PBMC group(P<0.05).Conclusions:Use of hCG-producing PBMCs(transfected PBMC)has more influence on endometrial receptivity.

Relationship between Parent-Child Attachment and Problem Behaviors among Chinese Firstborn Children in Family Transitions: A Meta-Analysis

The implementation of China’s three-child fertility policy has led to a notable increase in multiple-child families.Notably,firstborn children experience a significant transition from being an only child to a non-only child.This transition is associated with problematic behaviors,affecting their social adjustment,sibling relationships,and family harmony.Although several studies have examined the relationship between parent-child attachment and problem behaviors exhibited byfirstborn children during family transitions,thefindings have been inconsistent.Hence,a meta-analytic study was undertaken to elucidate the inconsistencies in this relationship and explore the moderating factors that may contribute to these discrepancies.Using a systematic literature retrieval and screening method,12 effect sizes were derived from the 10 eligible articles,encompassing a sample size of 5319.The meta-analysis demonstrated a low negative association between parent-child secure attachment and problem behaviors exhibited byfirstborn children during family transitions.Furthermore,the present study investigates potential moderator factors,such as children’s age and geographic region,to gain a more nuanced understanding of the relationship.Consequently,the establishment of parent-child attachment relationships has the potential to mitigate problem behaviors observed infirst-born children during family transitions.The implications of thesefindings indicate that parents can nurture secure attachment bonds with their children by demonstrating sensitive responsiveness,employing positive parenting practices,and fostering emotional availability.These efforts contribute to the cultivation of secure internal working models and positive behavioral manifestations withinfirst-born children,which in turn affect their relationships with siblings.

The Evolving Bipartite Network and Semi-Bipartite Network Models with Adjustable Scale and Hybrid Attachment Mechanisms

The bipartite graph structure exists in the connections of many objects in the real world, and the evolving modeling is a good method to describe and understand the generation and evolution within various real complex networks. Previous bipartite models were proposed to mostly explain the principle of attachments, and ignored the diverse growth speed of nodes of sets in different bipartite networks. In this paper, we propose an evolving bipartite network model with adjustable node scale and hybrid attachment mechanisms, which uses different probability parameters to control the scale of two disjoint sets of nodes and the preference strength of hybrid attachment respectively. The results show that the degree distribution of single set in the proposed model follows a shifted power-law distribution when parameter r and s are not equal to 0, or exponential distribution when r or s is equal to 0. Furthermore, we extend the previous model to a semi-bipartite network model, which embeds more user association information into the internal network, so that the model is capable of carrying and revealing more deep information of each user in the network. The simulation results of two models are in good agreement with the empirical data, which verifies that the models have a good performance on real networks from the perspective of degree distribution. We believe these two models are valuable for an explanation of the origin and growth of bipartite systems that truly exist.

湍流环境下颗粒与气泡黏附过程的数值模拟研究

研究湍流环境中颗粒与气泡的黏附过程对于探究浮选微观过程具有重要意义。基于EDEM的API(应用程序编程接口)二次开发模块,建立了颗粒与气泡黏附过程相互作用的三维离散元法(DEM)模型。在Fluent软件中通过构建规则格栅以激发各向同性的湍流,并将湍流环境通过计算流体力学-离散元(CFD-DEM)加入到EDEM软件中。模拟了颗粒粒径为0.10、0.15、0.20、0.25和0.30 mm,颗粒密度为1500、2000和2500 kg/m^(3),球形度为0.746~0.854的不规则颗粒,和气泡直径为1.00、1.20、1.60和2.00 mm,在气泡与格栅间距离为1.00、1.50、2.00和3.00 mm的湍流环境下颗粒与气泡的黏附过程。研究了颗粒、气泡、流场各参数对于颗粒与气泡黏附过程的影响。结果发现,无论规则颗粒还是不规则颗粒在湍流环境中与气泡的黏附均存在临界脱附流速(颗粒与气泡发生脱附的最小湍流流场流速)。密度大的颗粒和粒径大的颗粒与气泡黏附的临界脱附流速更小,表明粒径和密度大的颗粒与气泡难以稳定黏附。气泡的直径越大,颗粒与气泡稳定黏附的临界脱附流速越小,颗粒越难以稳定黏附。在相同的流速下,气泡与格栅间距离越小,则流场湍流强度越大,颗粒与气泡稳定黏附的临界脱附流速越小,表明湍流强度的增加不利于颗粒与气泡的稳定黏附。球形度小的颗粒与气泡稳定黏附的临界脱附流速也较小,表明球形度小的颗粒与气泡难以稳定黏附。

在言语交际过程中,说话人口语表达的韵律线索对交际双方的语言理解发挥着重要作用。为了深入了解中国英语学习者英语口语产出的韵律线索与预期表达含义之间的相关性,本文以中国大学英语学习者为研究对象,采用基于情境的半开放式口语产出任务,考察在特定的情境化实验条件下,被试对英语介词短语挂靠造成的歧义句的朗读任务完成情况。研究结果表明:中国大学英语学习者具有对口语韵律特征与句法结构之间关系的潜在敏感性,能够通过口语的韵律停顿和音高重音实现对英语介词短语动、名词挂靠引起的歧义的消解。本研究结果进一步证实了英语口语韵律特征与预期含义之间的相互关系,凸显了韵律训练在大学英语课堂教学中的重要性,为高校英语听说及阅读教学实践的开展提供了参考建议。

附加消能子结构在抗震加固工程中的应用

介绍了消能子结构的研究现状,文中以某小学教学楼抗震加固工程为例,阐述了采用附加消能子结构配合屈曲约束支撑进行抗震加固的设计过程,采用阵型分解反应谱法和时程分析法分析并对比了加固前后结构的抗震性能变化,基于现有研究成果,进行了消能子结构的加固设计和罕遇地震作用下的承载力复核。结果表明:采用附加消能子结构对结构进行抗震加固,在提高建筑抗震性能的同时,可以不影响建筑内部功能。加固后,结构整体刚度增加,自振周期变短,层间剪力增大,整体变形变小,结构的整体受力状态和变形模式得到改善,房屋整体抗震性能提升。罕遇地震作用下,结构整体塑性程度较低,损伤屈服机制更加合理,可以实现“大震不倒”的设防目标。消能子结构为连接消能器和主体结构的关键构件,应重点进行设计,采用柱的N-M曲线进行承载力复核比较便捷。文中设计思路可为类似工程提供借鉴和参考。
