Examining the impacts of backpackers′identity on their subjective well-being: The mediating role of self-esteem(背包客身份认同对主观幸福感的影响)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2022
已有研究表明,在“日常生活世界”形成的群体身份认同能提升人们的主观幸福感。作为对当前社会快速变化的一种回应,背包旅行能提供展露自我的“自由空间”,建构独特的背包客身份认同。为探明背包客在“旅游世界”建构的身份认同是否显著提升其主观幸福感这一问题,基于社会认同理论和自我决定理论,将自尊作为中介变量,检验了背包客身份认同与主观幸福感之间的关系。通过问卷调查(n=400)收集数据,运用结构方程模型偏最小二乘法(PLS-SEM)进行统计分析。发现:(1)背包客身份认同的自我归类维度 ...

基于群体感应相关菌群分析的HMBR膜污染控制研究

open access: yesGongye shui chuli, 2022
微生物群体感应现象已经在污水处理中被验证并应用于膜污染控制,但是其在复合式膜生物反应器(HMBR)中的膜污染控制研究鲜有报道。构建了HMBR污水处理系统,并在不同污泥龄(SRT=10、20、30 d)下运行HMBR设备,通过分析出水水质考察HMBR污水处理系统对污染物的去除效能;采用高通量测序检测群体感应相关菌群的群落结构,并结合跨膜压差、信号分子浓度深入解析群体感应调控HMBR膜污染的机理。实验结果表明,HMBR在SRT=30 d的工况下出水水质最好,膜组件运行周期最长,为最佳工况 ...

群体猝灭技术在控制MBR生物污染中的研究进展

open access: yesGongye shui chuli, 2021
膜生物反应器(MBR)广泛用于处理市政污水,但膜污染仍是MBR的应用瓶颈。基于微生物群体感应(QS)理论的群体猝灭(QQ)技术是一种具有较好前景的膜污染控制方法。QQ技术可干扰微生物的QS系统,进而抑制胞外聚合物的分泌和生物膜的形成,从根本上达到控制MBR生物污染的目的。对利用QQ技术控制MBR生物污染的研究进展进行总结,提出该技术面临的挑战,并对今后采用QQ技术减缓膜污染的研究进行展望。

Off‐Task Talk to Manage Relationship Work During Student Group Work in Second Language Classrooms

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This paper presents a conversation analytic study on student relationship work in off‐task talk (OTT) during group work in foreign language classrooms. Often seen as disengagement from tasks, OTT's social and relational functions in student classroom group interaction and formation remain underexplored.

“The Land's Been Queer Longer Than the Colonizers Have Been Here. Hiy Hiy.” Impacts of Anti‐Queer and Trans Policies and Resistance Through Art, Queer Joy, and Worldmaking Among Youth

open access: yesSexuality, Gender &Policy, Volume 9, Issue 4, November 2026.
ABSTRACT This study explores how 2SLGBTQ+ youth in Alberta, Canada—the country's most Conservative province—mobilize queer joy as a form of resistance amid rising anti‐queer and anti‐trans policies under a settler colonial, cisheteropatriarchal regime. Drawing from youth‐produced collages, we demonstrate that this visual arts‐based participatory method

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy

open access: yesPolicy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.
