This case study describes the care provided to a female patient with borderline personality disorder (BPD) who presented to the emergency department (ED). While people with borderline personality disorder use emergency services frequently, clinicians often face difficulties when providing medical and behavioral services to these patients. It may be difficult for nurse practitioners to determine if a patient with BPD who presents to the ED in crisis should be admitted, medicated, observed, or discharged. Self-harm is frequently confused with suicide attempts, which can result in unnecessary hospitalizations. This case study seeks to examine the proper management and difficulties encountered by healthcare providers in managing crises involving individuals with BPD in ED settings. The case study underscores the significance of thorough evaluation, recognition of BPD characteristics, active engagement in treatment, the therapeutic alliance, and the emphasis on interpersonal connections and stressors alongside the utilization of psychopharmacology. 展开更多

Objective:The combination of science and art in nursing is essential for providing effective care.Since art is inherent and a part of human personality traits,it is believed that nurses’personality traits are important to achieve this cohesive combination in nursing.Accordingly,this study was conducted to determine the relationship between nurses’personality traits and the esthetics of nursing care.Methods:A cross-sectional descriptive design was employed.Study participants that consisted of 95 nurses and 285 patients from health centers in Iran were selected by convenience sampling method.Measures included the five-factor personality questionnaires(NEO-FFI)scale and Esthetics of Nursing Care Scale(ENCS).Results:The findings indicated a significant relationship between neuroticism(r=−0.149,P=0.028)and extraversion traits(r=0.136,P=0.045)of nurses in esthetics nursing care.In this study,no significant relationship was found between the personality traits and esthetics of nursing care using nurses’demographic information.Conclusions:The esthetics of nursing care depends on nurse personality traits.Since the art of nursing complements the expected care,it is suggested that nursing managers pay attention to the personality traits of nurses in planning to provide effective care. 展开更多

This study investigated the political,economic,social,and cultural environment perceptions on international students that define their acculturation and health related quality of life.Participants were 117 international students from 32 countries attending a Chinese university(females=43%,mean age=21.17 years,SD=4.45 years).They reported on their acculturation to China and physical and psychological well-being.Results from t-tests and correlation analyses indicate political liberals had more positive attitudes toward China than the conservatives,and higher self-reported physical and psychological results.Higher scores on the“interdependence”dimension of self-construal,as well as the“extraversion”and“emotional stability”dimensions of personality traits,were associated with more positive views of China and better health outcomes.These findings are consistent with Berry’s framework for acculturation,which posits that individual-level variables are related to cultural adaptation,and that cultural adaptation is associated with improved physical and mental health.International student offices at host universities should implement comprehensive support programs,including language assistance,cultural orientation,and social integration initiatives to effectively enhance the health related quality of life of international students. 展开更多

Social media outlets deliver customers a medium for communication,exchange,and expression of their thoughts with others.The advent of social networks and the fast escalation of the quantity of data have created opportunities for textual evaluation.Utilising the user corpus,characteristics of social platform users,and other data,academic research may accurately discern the personality traits of users.This research examines the traits of consumer personalities.Usually,personality tests administered by psychological experts via interviews or self-report questionnaires are costly,time-consuming,complex,and labour-intensive.Currently,academics in computational linguistics are increasingly focused on predicting personality traits from social media data.An individual’s personality comprises their traits and behavioral habits.To address this distinction,we propose a novel LSTMapproach(BERT-LIWC-LSTM)that simultaneously incorporates users’enduring and immediate personality characteristics for textual personality recognition.Long-termPersonality Encoding in the proposed paradigmcaptures and represents persisting personality traits.Short-termPersonality Capturing records changing personality states.Experimental results demonstrate that the designed BERT-LIWC-LSTM model achieves an average improvement in accuracy of 3.41% on the Big Five dataset compared to current methods,thereby justifying the efficacy of encoding both stable and dynamic personality traits simultaneously through long-and short-term feature interaction. 展开更多

Background and Objective Social anxiety arising from intensive social media usage(SMU)among adolescents and youth has gained extensive attention in recent years due to its negative influence on mental health and academic performance.In spite of that,there is a dearth regarding the etiology of SMU-related social anxiety.This study aims to further clarify the influence of introversion personality on SMU-related social anxiety and the mechanism underlying such an association and provide a new perspective for developing effective intervention strategies for the highly prevailing SMU-related anxiety among Chinese college students.Methods A cohort of 979 college students(266 males and 713 females)aged 20.90±1.91 years was enrolled in this cross-sectional study.Four measures including the"extroversion"domain of Eysenck Personality Questionnaire Revised,Short Scale(EPQ-R-S E),Interaction Anxiousness Scale(IAS),Mobile Phone Addiction Index(MPAI),and Social Anxiety Scale for Social Media Users(SAS-SMU)were used to evaluate the influence of introversion personality on SMU-related social anxiety that was potentially mediated sequentially by interaction anxiousness and mobile phone addiction.Hayes PROCESS was used for correlation and mediation analysis.Results Interaction anxiousness(indirect effect=-1.331,95%CI:-1.559--1.122)partially mediated the association between introversion personality and SMU-related social anxiety.Besides,a sequential mediation of interaction anxiousness and mobile phone addiction in the link between introversion personality and SMU-related social anxiety was revealed(indirect effect=-0.308,95%CI:-0.404--0.220).No significant mediating effect was found with mobile phone addiction in the association between introversion personality and SMU-related social anxiety.Conclusion Targeting interaction anxiousness and mobile phone addiction may represent an efficient strategy alleviating SMU-related social anxiety among Chinese college students with introversion personality. 展开更多

Honey trap is a really common type of stratagem which can be seen in many fields such as military,politics,diplomacy,and business.You can easily find many examples of it in the historical books of many different countries.As time went by,because of the changes of human thinking,just relying on the beautiful appearance could not ensure the success of a honey trap.Therefore,there appeared a new type of honey trap called personality grooming.As a matter of fact,the original form of personality grooming appeared a few centuries ago.However,at the very beginning,personality grooming was not directly related to honey trap.It is an interesting feature of honey trap that its forms will change due to the changes of the times.In this process,honey trap and personality grooming gradually integrate,developing a new type of honey trap.Compared with the traditional ones,this type of honey trap is much harder to guard against. 展开更多

BACKGROUND Depression is a common mental disorder among adolescents,characterized by a high rate of suicide and self-harm,which not only is devastating to families but also has a negative impact on society.Psychological factors such as impulsive personality,perceived chronic social adversity(PCSA),and sense of security are closely associated with suicide risk in adolescents with depression.Few studies have been conducted on the relationship between these factors.AIM To explore the impact of impulsive personality on suicide risk in adolescents with depression and the chain mediating effect between PCSA and sense of security.METHODS This study is a retrospective study.A total of 200 adolescents with depression who visited the Guangxi Zhuang Autonomous Region Maternal and Child Health Hospital from January 2021 to December 2023 comprised the study cohort.The PCSA scale,Security Questionnaire,Barratt Impulsiveness Scale,and Beck Scale for Suicide Ideation were used to evaluate depression.RESULTS Suicide risk was positively correlated with impulsive personality and PCSA(P<0.05),whereas sense of security was negatively correlated with suicide risk,impulsive personality,and PCSA(P<0.05).The total indirect effect of PCSA and sense of security on impulsive personality and suicide risk was 35.43%,with the mediating effect of PCSA and sense of security contributing 16.53%and 15.75%,respectively.PCSA and sense of security exhibited a chain mediating effect between impulsive personality and suicide risk,accounting for 3.15%.CONCLUSION The suicide risk of adolescents with depression is significantly associated with impulsive personality,PCSA,and sense of security.Impulsive personality affects the suicide risk of adolescents with depression both directly and indirectly,with the latter occurring via PCSA and sense of security. 展开更多

We examined the relationship between social support and career adaptability,as well as the mediating roles of proactive personality and career decision-making self-efficacy in this process.A total of 1354 Chinese college students(female=964;mean age=19.53 years,SD=1.33 years)completed an online questionnaire.Path analysis indicated that social support was positively associated with higher levels of career adaptability.Both proactive personality and career decision-making self-efficacy served as parallel mediators,strengthening the relationship between social support and career adaptability.The complete chain mediation analysis revealed that social support influences career adaptability primarily through proactive personality,which in turn enhances career decision-making self-efficacy,further contributing to increased career adaptability.These findings extend career capital theory by demonstrating that social and psychological resources jointly facilitate career adaptability. 展开更多

China is a fast-developing nation,especially in traditional concepts of emphasis on agricultural production,with millions of highly educated college students as new generations of workers enter the workforce,while promoting the booming agriculture industry in China.Concerning these new generations of ambitious college students,it is a pretty attractive career to leverage their knowledge to spread their local special rural agricultural products(agri-products)to well-known places around the nation,even the world.Meanwhile,the Chinese government also supports rural products branding via internet marketing as well as the exploitation of online technologies.Su et al.pointed out that governments in China are expected to take more effective measures to enhance adoption rates of online purchases and sales technology,in particular for entrepreneurial farmers[1].Currently,the most existing phenomenon in China is that quantities of regional rural products with excellent quality but without national popularity.Thereby,it is significant to enhance the popularity of various brands in regional agricultural products using internet marketing,and also contribute to the nation’s strategy of rural revitalization.To appeal to the nations’strategy,we are supposed to make use of brand personality(BP)traits,which probably contribute to robust internet branding of regional agricultural products.Our research will focus on the influences of differential dimensions of brand personality(BP)in terms of common rural products,additionally,we also attempt to design a BP model for internet branding of agricultural products in China.Furthermore,from the two perspectives of characteristics in rural areas(agricultural producers and agricultural consumers),measures to assist agricultural producers in building their brands through the application of internet tools and marketing should be recognized.On the other side,methods to enhance agricultural consumers’brand loyalty also need to be captured. 展开更多

Animals constantly need to evaluate available external and internal information to make appropriate decisions.Identifying,assessing,and acting on relevant cues in contexts such as mate choice,intra-sexual competition,and parental care is particularly important for optimizing individual reproductive success.Several factors can infuence decision-making,such as external environmental cues and the animal’s own internal state,yet,we have limited knowledge on how animals integrate available information.Here,we used an entire island population(57 males,53 females,and 1,109 tadpoles)of the neotropical brilliant-thighed poison frog Allobates femoralis to investigate how 2 factors(olfactory cues and personality traits)infuence the ability of males to fnd and use new resources for tadpole deposition.We experimentally manipulated the location of tadpole deposition sites and their associated olfactory cues,and repeatedly measured exploration and boldness in adult males.We further reconstructed tadpole deposition choices via inferred parent–offspring relationships of adult frogs and tadpoles deposited in our experimental pools using molecular parentage analysis.We found that the discovery and use of new rearing sites were heavily infuenced by olfactory cues;however,we did not fnd an effect of the measured behavioral traits on resource discovery and use.We conclude that in highly dynamic environments such as tropical rainforests,reliable external cues likely take priority over personality traits,helping individuals to discover and make use of reproductive resources. 展开更多

Investigating the role of Big Five personality traits in relation to various health outcomes has been extensively studied. The impact of “Big Five” on physical health is here explored for older Europeans with a focus on examining age groups differences. The study sample included 378,500 respondents derived from the seventh data wave of Survey of Health, Aging and Retirement in Europe (SHARE). The physical health status of older Europeans was estimated by constructing an index considering the combined effect of well-established health indicators such as the number of chronic diseases, mobility limitations, limitations with basic and instrumental activities of daily living, and self-perceived health. This index was used for an overall physical health assessment, for which the higher the score for an individual, the worst health level. Then, through a dichotomization process applied to the retrieved Principal Component Analysis scores, a two-group discrimination (good or bad health status) of SHARE participants was obtained as regards their physical health condition, allowing for further con-structing logistic regression models to assess the predictive significance of “Big Five” and their protective role for physical health. Results showed that neuroti-cism was the most significant predictor of physical health for all age groups un-der consideration, while extraversion, agreeableness and openness were not found to significantly affect the self-reported physical health levels of midlife adults aged 50 up to 64. Older adults aged 65 up to 79 were more prone to open-ness, whereas the oldest old individuals aged 80 up to 105 were mainly affected by openness and conscientiousness. . 展开更多

This paper introduces a cutting-edge framework for personalized chronic pain management,leveraging the power of artificial intelligence(AI)and personality insights.It explores the intricate relationship between personality traits and pain perception,expression,and management,identifying key correlations that influence an individual’s experience of pain.By integrating personality psychology with AI-driven personality assessment,this framework offers a novel approach to tailoring chronic pain management strategies for each patient’s unique personality profile.It highlights the relevance of well-established personality theories such as the Big Five and the Myers-Briggs Type Indicator(MBTI)in shaping personalized pain management plans.Additionally,the paper introduces multimodal AI-driven personality assessment,emphasizing the ethical considerations and data collection processes necessary for its implementation.Through illustrative case studies,the paper exemplifies how this framework can lead to more effective and patient-centered pain relief,ultimately enhancing overall well-being.In conclusion,the paper positions the need of an“AI-Powered Holistic Pain Management Initiative”which has the potential to transform chronic pain management by providing personalized,data-driven solutions and create a multifaceted research impact influencing clinical practice,patient outcomes,healthcare policy,and the broader scientific community’s understanding of personalized medicine and AI-driven interventions. 展开更多

Two questions in the research of animal personality—whether there is a correlation between a personality trait and individual reproductive success,and what is the genetic basis underlying a personality trait—remain unresolved.We addressed these two questions in three shrub-nesting birds,the Azure-winged Magpie(Cyanopica cyanus,AM),White-collared Blackbird(Turdus albocinctus,WB),and Brown-cheeked Laughingthrush(Trochalopteron henrici,BL).The personality type of an individual was first identified according to its response to a territorial intruder.Then,we compared the fleeing distance,breeding parameters,and differential expressed genes(DEGs) in the brain transcriptome between bold and shy breeders.In the three species,bold breeders exhibited more aggressiveness towards an intruder of their territory than did shy breeders.The reproductive success of bold breeders was significantly higher than that of shy breeders in AM but not in WB and BL.The three species shared one DEG,crabp1,which was up-regulated in bold relative to in shy individuals.By regulating the expression of corticotropin-releasing hormone,higher crabp1 gene expression can decrease cellular response to retinoic acid.Therefore,bold individuals are insensitive to external stresses and able to exhibit more aggressiveness to intruders than their shier counterparts.Aggressiveness is beneficial to bold individuals in AM but not in WB and BL because the former could evoke neighbors to make the same response of defending against intruders but the latter could not.Although a personality trait may have the same genetic basis across species,its correlation with reproductive success depends largely on the life history style of a species. 展开更多

Although much work has focused on non-social personality traits such as activity, exploration, and neophobia, there is a growing appreciationthat social personality traits play an important role in group dynamics, disease transmission, and fitness and that social personality traits maybe linked to non-social personality traits. These relationships are important because behavioral syndromes, defined here as correlated behavioral phenotypes, can constrain evolutionary responses. However, the strength and direction of relationships between social and non-socialpersonality traits remain unclear. In this project, we examine social and non-social personality traits, and the relationships between them, in thepaper wasp Polistes fuscatus. With a novel assay, we identify 5 personality traits, 2 non-social (exploration and activity), and 3 social (aggression, affiliation, and antennation) personality traits. We also find that social and non-social personality traits are phenotypically linked. We find apositive correlation between aggression and activity and a negative correlation between affiliation and activity. We also find a positive correlation between exploration and activity. Our work is an important step in understanding how phenotypic linkage between social and non-socialbehaviors may influence behavioral evolution. As a burgeoning model system for the study of genetic and neurobiological mechanisms of socialbehavior, Polistes fuscatus has the potential to add to this work by exploring the causes and consequences of individual behavioral variation. 展开更多
