文摘Objective:To examine how emotional labor demands and strategies influence work engagement and occupational identity among Portuguese volunteer firefighters.Methods:Participants completed the Emotional Work Requirements Scale,Emotional Labour Scale,Utrecht Work Engagement Scale,and Social Identity Scale.Multiple linear regression analyses were conducted to assess the predictive effects of emotional labor demands and strategies on work engagement and occupational identity.Results:Emotional labor explained 11.8%of the variance in work engagement and 10.9%in occupational identity.Positive emotion expression significantly predicted higher work engagement and a stronger occupational identity,while the suppression of negative emotions predicted a weaker occupational identity.Other emotional labor dimensions were not significant.Conclusions:Findings underscore the dual role of emotional labor—as a resource when positive emotions are expressed and as a strain when negative emotions are habitually suppressed.Targeted interventions to promote authentic positive expression and effective emotional processing may enhance firefighters’well-being,strengthen crisis team performance,and benefit the communities they serve.Further research is needed to deepen the understanding of emotional labor in crisis response contexts.
文摘An earlier version of this paper has been presented online at the annual Conference of Canadian Sociological Association,during the Congress of Humanities and Social Sciences in Toronto in June 2025.It explores how rap music in Quebec,particularly through the work of the rap artist Webster and his collective Limoilou Starz(LS),serves as a tool for meaning-making,political expression,and resistance against racial profiling and police brutality experienced by Black youth in Quebec City.The study focuses on the song“SPVQ”(Service de police de la Ville de Québec)as a case study to analyze the encoding and reception of anti-racist messages within rap culture.Webster draws from a global tradition of socio-political rap-like that of African-American rappers KRS-One,LL Cool J,and Tupac-while anchoring his critique in the local realities of Limoilou,a marginalized,racially diverse district of Quebec City.Through a narrative,figurative,semantic,and ideological analysis of the song,the paper reveals how Webster articulates themes of police brutality,structural discrimination,economic marginalization,and resistance.The rapper’s message is both a form of testimony and a civic intervention.His broader activism is analyzed through ethnographic techniques-including participant observation and interviews during workshops,media appearances,and online campaigns.It translates these messages into tangible social practices.To explain the persistence of these injustices,the paper situates the issue within Quebec’s interculturalism framework,which ostensibly promotes dialogue and integration but often masks or even reinforces structural racism.This model maintains a symbolic majority/minority duality and conditions inclusion on conformity to a dominant White Francophone identity,thus rendering racialized youth as perpetual outsiders.

文摘Selective regulation of gene expression across distinct brain regions is crucial for establishing and maintaining subdivision identities.DNA methylation,a key regulator of gene transcription,modulates transcriptional activity through the conversion of 5-methylcytosine(5mC)to 5-hydroxymethylcytosine(5hmC).While DNA methylation is hypothesized to play an essential role in shaping brain identity by influencing gene expression patterns,its direct contribution,especially in primates,remains largely unexplored.This study examined DNA methylation landscapes and transcriptional profiles across four brain regions,including the cortex,cerebellum,striatum,and hippocampus,using samples from 12 rhesus monkeys.The cerebellum exhibited distinct epigenetic and transcriptional signatures,with differentially methylated regions(DMRs)significantly enriched in metabolic pathways.Notably,genes harboring clustered differentially hydroxymethylated regions(DhMRs)overlapped with those implicated in schizophrenia.Moreover,5mC located1 kb upstream of the ATG start codon was correlated with gene expression and exhibited region-specific associations with 5hmC.These findings provide insights into the coordinated regulation of cerebellum-specific 5mC and5hmC,highlighting their potential roles in defining cerebellar identity and contributing to neuropsychiatric diseases.
文摘BACKGROUND Global tumor incidence rises and therapies advance,driving oncology nursing specialization.Granting nurses prescriptive authority optimizes care but polarizes nurses'attitudes due to factors like risk and competence,hindering policy implementation.AIM To investigate the current status of the attitudes of oncology specialist nurses toward having prescribing authority,specifically concerning symptom management and supportive care in oncology practice,and we conducted a path analysis of their influencing factors.METHODS As participants in the survey,oncology specialist nurses working in hospitals of different grades in Jiangsu Province were selected from March 2025 to May 2025 using a stratified sampling method.The questionnaires were administered using the general information questionnaire,the beliefs and attitudes about nurses'prescriptive authority scale,the nurses'professional identity scale,and the selfefficacy scale.Pearson’s method was used to analyze the correlation between beliefs and attitudes about the prescriptive authority,professional identity,and self-efficacy of nurses.Multiple linear regression was performed to analyze the factors influencing the beliefs and attitudes of nurses’prescriptive authority.The Amos plug-in was used to construct structural equation models to analyze the influencing pathways.RESULTS A total of 329 questionnaires were distributed,and 328 valid questionnaires were returned(effective recovery rate:99.70%).The total score of the 328 oncology nurses on the beliefs and attitudes about nurses'prescriptive authority scale was 101.88±15.13,indicating a moderately high level.Univariate analysis revealed that gender and hospital grade were associated with this score(P<0.05).The Pearson correlation analysis revealed that self-efficacy was positively correlated with the scores of the beliefs and attitudes about nurses’prescriptive authority scale and the nurses’professional identity scale(r=0.4999,P<0.0001 and r=0.7048,P<0.05,respectively),whereas occupational identity was positively correlated only with the former(r=0.6209,P<0.05).Multiple linear regression analysis revealed occupational identity and self-efficacy as the factors influencing the scores of the beliefs and attitudes about nurses’prescriptive authority scale(P<0.05).The results of the path analysis revealed that selfefficacy significantly positively affected nurses’occupational identity and their beliefs and attitudes about having prescriptive authority;occupational identity played a mediating role between the two,with a mediating effect accounting for 54.46% of the total effect,and the structural equation model was well-fitted.CONCLUSION Oncology nurses have more positive attitudes toward prescriptive authority.In addition,self-efficacy positively and indirectly affects nurses’attitudes toward prescriptive authority through the mediating effect of occupational identity.This can be used as a basis for clinical practice to take targeted measures to improve nurses’self-efficacy and occupational identity,thus creating favorable conditions for effectively implementing the policy of prescriptive authority.
