Abstract

Although ecological grief is a common psychic response to socioecological losses, there are no shared spaces to engage with it in Western cultures—a symptom of the problematic way they conceive Nature as external and subordinate to humans. Seeking subversive impulses for paradigmatic transformation, this research centers queer-identifying eco-activists and -artists, and their practices of queer-ecological worldmaking. Arts-based research and interviews reveal the potential of melancholic grieving to create an understanding of interdependencies with the more-than-human world, as well as communities for healing. Impulses toward a joint liberation entail the extension of empathy and agency to the more-than-human world.  相似文献

In this study, we investigated how children evaluate gossipers. There are two conflicting ways in which children evaluate the gossiper of negative gossip about another person. One is that they perceive the gossiper of negative gossip as bad because saying something negative about another person can be seen as indirect aggression. The other is that they perceive the gossiper of negative gossip as good because such gossip is beneficial to regulate their relationship with the gossip's target. To address the issue, we asked 7- and 8-year-olds to choose the gossiper of negative gossip or the gossiper of neutral gossip as a cooperative partner and to distribute resources between the gossipers. We found that the children often did not choose the gossiper of negative gossip as a partner and did not distribute many resources to her, indicating a perception of the negative gossiper as bad. This suggests that children's evaluation of a gossiper is influenced by the valence of gossip rather than the value of gossip.  相似文献

Social motivation—the psychobiological predisposition for social orienting, seeking social contact, and maintaining social interaction—manifests in early infancy and is hypothesized to be foundational for social communication development in typical and atypical populations. However, the lack of infant social-motivation measures has hindered delineation of associations between infant social motivation, other early-arising social abilities such as joint attention, and language outcomes. To investigate how infant social motivation contributes to joint attention and language, this study utilizes a mixed longitudinal sample of 741 infants at high (HL = 515) and low (LL = 226) likelihood for ASD. Using moderated nonlinear factor analysis (MNLFA), we incorporated items from parent-report measures to establish a novel latent factor model of infant social motivation that exhibits measurement invariance by age, sex, and familial ASD likelihood. We then examined developmental associations between 6- and 12-month social motivation, joint attention at 12–15 months, and language at 24 months of age. On average, greater social-motivation growth from 6–12 months was associated with greater initiating joint attention (IJA) and trend-level increases in sophistication of responding to joint attention (RJA). IJA and RJA were both positively associated with 24-month language abilities. There were no additional associations between social motivation and future language in our path model. These findings substantiate a novel, theoretically driven approach to modeling social motivation and suggest a developmental cascade through which social motivation impacts other foundational skills. These findings have implications for the timing and nature of intervention targets to support social communication development in infancy.

Highlights

  • We describe a novel, theoretically based model of infant social motivation wherein multiple parent-reported indicators contribute to a unitary latent social-motivation factor.
  • Analyses revealed social-motivation factor scores exhibited measurement invariance for a longitudinal sample of infants at high and low familial ASD likelihood.
  • Social-motivation growth from ages 6–12 months is associated with better 12−15-month joint attention abilities, which in turn are associated with greater 24-month language skills.
  • Findings inform timing and targets of potential interventions to support healthy social communication in the first year of life.

人们追求人际和谐的动机具有双重性,一方面是为了促进和谐,另一方面是为了避免破裂,两种动机驱使人们在面对冲突时采取不一样的应对策略。那么,谈判作为一种与冲突密不可分的情境,谈判者的和谐的动机将会对他们的谈判结果产生什么影响呢?本研究整合和谐动机和谈判两方面的文献,探讨了在整合性谈判中两种不同的和谐动机与谈判者的行为以及谈判结果之间的关系。研究结果表明,1)在个体层面上,谈判者的促进和谐动机与其个体收益以及对谈判双方关系的评价正相关,而避免破裂动机与其个体收益以及对谈判双方关系的评价负相关;2)在谈判对子层面上,谈判双方总体的促进和谐与谈判双方的联合收益正相关。本研究不仅进一步论证了和谐动机的概念效度,而且从理论上论证了和谐动机与谈判的关系,对于谈判者具有实践意义。  相似文献

在社交焦虑认知行为模型的理论视角下,本研究拟探讨负面评价恐惧、不确定性容忍度和依赖型自我构念对社交焦虑的影响及其作用机制。以424名大学生为被试,使用问卷调查法的研究结果表明:(1)负面评价恐惧对社交焦虑有显著预测作用,且不确定性容忍度在这一关系中的中介作用显著;(2)不确定性容忍度的间接效应受到依赖型自我构念的调节。具体而言,该中介效应在高依赖型自我构念群体中更为显著。本研究结果不仅有助于揭示负面评价恐惧对社交焦虑的影响及其作用机制,而且对社交焦虑的预防和干预也有一定的理论和实践指导价值。  相似文献

ABSTRACT

Objectives: This article addresses the methodological controversies surrounding the issue of how to evaluate the psychotherapies. It proposes to identify the principles of an integrative and stratified model in order to report the results of analytical therapy (its efficacy) based on the very effectiveness of its processes. Thus, the uniqueness of the case is put at the center of the evaluation setting.

Methods: Drawing on science studies, the authors engage in a reflexive exercise on the problem of psychoanalysis’ evaluation based on methodological questions raised in the field over time and current issues related to practice.

Results: First, the regularly asserted opposition between the norms of analytical practice and those governing standard evaluation procedures is reinterpreted as the effect of a lack of intermediate epistemic patterns.

Second, the fundamental principles of an integrative model are considered so as to translate and articulate a set of heterogeneous requirements into distinct strata.

Discussion: Since psychoanalysis is fundamentally a case-by-case practice characterized by inequivalence and unexpectedness, its utmost aim is to use a type of effectiveness based on the singularity of the case. However, this does not prevent it from being evaluable provided that the epistemic levels of the evaluation are clearly differentiated.  相似文献

A comprehensive analysis of clustering techniques is presented in this paper through their application to data on meteorological conditions. Six partitional and hierarchical clustering techniques (k-means, k-medoids, SOM k-means, Agglomerative Hierarchical Clustering, and Clustering based on Gaussian Mixture Models) with different distance criteria, together with some clustering evaluation measures (Calinski–Harabasz, Davies–Bouldin, Gap and Silhouette criterion clustering evaluation object), present various analyses of the main climatic zones in Spain. Real-life data sets, recorded by AEMET (Spanish Meteorological Agency) at four of its weather stations, are analyzed in order to characterize the actual weather conditions at each location. The clustering techniques process the data on some of the main daily meteorological variables collected at these stations over six years between 2004 and 2010.  相似文献

How to take active and effective measures to evaluate the university scientifically and rationally has been an eternal topic that the educational circles are constantly exploring. Based on the principle of index construction, the current educational performance evaluation index system is improved and a more reasonable evaluation index system is formed. On this basis, taking the sample data in 2017 as an example, the principal component analysis method is used to reduce the dimension of input and output indicators and eliminate the correlation between indicators, and three principal components of input and three principal components of output are obtained. Secondly, data envelopment analysis model is established, and the data processed are analyzed with the help of MATLAB and DEAP2.1 operation software. The efficiency of these 24 colleges and universities is compared to understand the efficiency and differences of each college. Moreover, projection analysis of non-DEA effective DMU is completed and the direction of improvement and the specific adjustment value are pointed out.  相似文献

The concept of exploitation and potentially exploitative real‐world practices are the subject of increasing philosophical attention. However, while philosophers have extensively debated what exploitation is and what makes it wrong, they have said surprisingly little about what might be required to remediate it. By asking how the consequences of exploitation should be addressed, this article seeks to contribute to filling this gap. We raise two questions. First, what are the victims of exploitation owed by way of remediation? Second, who ought to remediate? Our answers to these questions are connected by the idea that exploitation cannot be fully remediated by redistributing the exploiter's gain in order to repair or compensate the victim's loss. This is because exploitation causes not only distributive but also relational harm. Therefore, redistributive measures are necessary but not sufficient for adequate remediation. Moreover, this relational focus highlights the fact that exploitative real‐world practices commonly involve agents other than the exploiter who stand to benefit from the exploitation. Insofar as these third parties are implicated in the distributive and relational harms caused by exploitation, there is, we argue, good reason to assign part of the burden of remediation to them.  相似文献
