  • The impact of resource type on green consumption: Is time or money more important?

    Subjects: Psychology >> Management Psychology submitted time 2023-07-11

    Abstract: Time and money are two important resource types. Individuals’ green consumption behavior is inevitably affected by these two resources in cognitive thinking and decision-making. However, the underlying mechanism of how resource type affects green consumption is still unclear. The present study introduces time and money into the field of green consumption. On the one hand, based on construal level theory and human value, it reveals how time resources promote green consumption and how money resources decrease green consumption. On the other hand, from the perspective of individuals, enterprises, and products, it combines experiments to explore the boundary conditions of time and money affecting green consumption. It further introduces emotional response level, environmental self-responsibility, and product effectiveness perception as mediating factors to build a theoretical framework of the impact of resource type on green consumption. These studies not only explore the positive role of time and money resources in promoting green consumption, but also provide new ideas for companies to use resource type to guide green consumption.

  • 子宫内膜癌组织中DAPK3和c-Myc的表达及其与患者预后的关系

    Subjects: Medicine, Pharmacy >> Preclinical Medicine submitted time 2017-12-27 Cooperative journals: 《南方医科大学学报》

    Abstract: Objective To investigate the expressions of DAPK3 and c-Myc and their prognostic value in endometrial carcinoma (EC). Methods The expressions of DAPK3 and c-Myc were detected immunohistochemically in 132 surgical specimens. The relationship between DAPK3 and c-Myc protein expressions and the clinicopathological features of the patients was evaluated. Results Immunohistochemical analysis revealed low DAPK3 expression in 60.61% (80/132) and high c-Myc expression in 53.79% (71/132) of the specimens of EC. Both DAPK3 expression and c-Myc expression were significantly correlated with FIGO stage (P=0.034 and 0.015, respectively) and lymph node metastasis (P=0.022 and 0.031, respectively). DAPK3 expression was closely correlated with the histological grade (P=0.027) and depth of myometrial invasion (P=0.011). Kaplan-Meier survival analysis indicated that patients with low DAPK3 expressions had a shorter overall survival rate than those with high DAPK3 expressions (P=0.023), while patients with high c-Myc expressions had poorer prognoses than those with low c-Myc expressions (P=0.002). Spearman correlation analysis showed that DAPK3 and c-Myc expressions were negatively correlated (P<0.001, r=−0.310). Multivariate analysis identified a high c-Myc expression as the independent predictor of the prognosis of EC (P=0.007). Conclusions A low expression of DAPK3 and a high expression of c-Myc are associated with aggressive and metastatic behaviors of EC, and their detection may help to predict the prognosis of the EC patients.

  • Design and Implementation of Ontology-based Citation Knowledge Service Prototype System

    Subjects: Library Science,Information Science >> Library Science submitted time 2023-07-26 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] For now, the construction of domestic citation database had already begun to take shape. In the development of citation knowledge services, the current organization and retrieval methods of scientific literature resources make the current citation knowledge service model unable to reveal the structure or relationship between citations, which caused difficulties for the acquisition, sharing and utilization of citations.[Method/process] This paper took citation data as the research object, acquired and sorted all kinds of knowledge and explored the semantic relationship between citations. Two ontology named "scientific researcher ontology" and "citation knowledge ontology" were constructed, and an ontology-based citation knowledge service prototype system was designed and implemented.[Result/conclusion] Conducts empirical research on the construction of ontology-based citation knowledge service system, The result proves that the ontology-based citation knowledge service system has the expected goals and functions.

  • 独立、协同和平衡视角下的单维式基本心理需要满足

    Subjects: Psychology >> Developmental Psychology submitted time 2023-03-28 Cooperative journals: 《心理科学进展》

    Abstract: Studying basic psychological needs in a unidimensional way supplements the general framework of need satisfaction research by exploring the uniqueness of each need satisfaction (i.e., autonomy, relatedness, or competence satisfaction). This article reviews the theoretical basis of the psychological mechanisms (the intrinsic motivation and the internalization of extrinsic motivation) and the research status quo of the need satisfaction successively from three unidimensional perspectives, i.e., the additive, synergistic and balanced perspectives. Notably, inspired by the three perspectives, the article provides insights for the “limited interchangeability” of each need satisfaction’s influence on individuals’ psychological functioning. Future studies may keep digging the need satisfactions from the three unidimensional perspectives, and explore the compensatory association among the three need satisfactions, the neurological basis of each need satisfaction, and the basic psychological need frustrations in a unidimensional way.

  • Land use change based on production-living-ecology spaces and its driving forces in Shaanxi Province

    Subjects: Geosciences >> Geography submitted time 2023-03-15 Cooperative journals: 《干旱区地理》

    Abstract: : Shaanxi Province connects the eastern and western parts of China. Hence, its rational land-use planning is crucial to promote high-quality regional development. Guided by land functions, the study explored the characteristics and change trends of the production-living-ecology spaces in Shaanxi Province from 2000 to 2020 using various modeling methods (e.g., a land-use transfer matrix). Subsequently, the mechanisms of distribution changes at different scales were analyzed. The following are the conclusions. (1) The integrated land-use dynamic attitudes of the spaces fluctuated at 0.2%, with two instances of increase: the expansion of living spaces and the increase of ecological spaces. Among the single land- use dynamic attitudes, the rates of living spaces were the highest, mostly positive; the rates of production spaces were the second, mostly negative; and the rates of change of ecological spaces were mainly positive, stable at 0.1%. (2) From 2000 to 2020, the size of production space changed the most, decreasing by 2913 km2 , and other spaces increased, among which ecological spaces increased more. In the secondary classification, the size of production ecological spaces changed the most, decreasing by 4036 km2 , whereas the remaining types increased (except for the potential ecological space), and green ecological space increased the most (by 2025 km2 ). (3) The spatial distribution of spaces relates to topography. The ecology spaces that occupy the largest area were mainly located in the south, the production spaces were mainly located in the central area, and the living spaces that occupy the smallest area were mainly located in the Xi’an metropolitan zone and expanded outward yearly. (4) A factor detector indicates that the population factors dominated the spatial changes of production-living-ecology spaces in Shaanxi Province. Meanwhile, an interaction detector reveals that the results of multifactor could better explain the spatial distribution than those of single factors.

  • 员工何以蓬勃旺盛?影响工作旺盛感的组织情境与理论模型

    Subjects: Psychology >> Developmental Psychology submitted time 2023-03-28 Cooperative journals: 《心理科学进展》

    Abstract: Thriving at work is a psychological state in which individuals experience both the sense of vitality and learning at work. The contextual enablers, such as leadership, organizational support and fairness, job characteristics, and peers, can facilitate thriving at work. Drawing from the Trait Activation Theory and Self-Determination Theory, the model of “psychological mechanism of organizational context affecting thriving at work” is built: “omnibus” and “discrete” contextual factors can either directly affect the satisfaction of basic psychological needs, or activate traits, then affect the satisfaction of basic psychological needs and subsequently influence thriving at work. Future studies are suggested to pay more attention to the “omnibus” context and its intermediary mechanism; to conduct the multi-level research that simultaneously examines individual and contextual variables, or articulates the social and task levels; and to utilized the dynamic research method to study the relationship between organizational context and thriving at work, and hence to predict thriving at work.

  • 信任以稀为贵?下属感知被信任如何以及何时导致反生产行为

    Subjects: Psychology >> Social Psychology submitted time 2023-03-27 Cooperative journals: 《心理学报》

    Abstract: Trust is a crucial part of interpersonal relationships within work environments. Previous research has revealed that feeling trusted, or “the perception that another party is willing to accept vulnerability to one’s actions,” by one’s supervisor benefits both subordinates and organizations in various ways such as enhancing organization-based self-esteem and improving individual and organizational performance. While extant research has provided insightful knowledge to help us understand the beneficial effects of feeling trusted, we know little about its potential drawbacks. We suggest that scholars may have overstated the benefits of feeling trusted and overlooked its potential costs. Thus, several important questions are arisen: When dose feeling trusted induce employees subsequent counterproductive work behavior (CWB), and Why? Drawing upon self-evaluation theory and trust literature, we propose that feeling trusted by their supervisors may promote employees’ psychological entitlement, which leads to subsequent CWB. Furthermore, we consider the perceived rarity of trust as a boundary condition and suggest that when employees perceive the rarity of trust is high, feeling trusted is more likely to make them feel psychologically entitled, thus leading to CWB. To test our theoretical model, we conducted three studies, including two experiments (i.e., Study 1 and 2) and one multi-wave, multi-source field study (i.e., Study 3) among diverse samples. In Study 1, we invited 115 full-time employees through the alumni networks of several large universities in China to participate our experiment. Participants were randomly assigned to one of two experimental conditions: the feeling trusted condition (n = 58) versus the control condition (n = 57). Feeling trusted was manipulated by the critical incident technique. Each participant was required to recall and describe a recent interaction with their supervisor. Next, participants completed an ostensibly unrelated task (filler task) and reported psychological entitlement, manipulation check, and demographics. In Study 2, we recruited 145 full-time working adults as participants from the United States using Amazon’s Mechanical Turk. Participants first reported the perceived rarity of trust in their organizations. Then, they were randomly assigned to one of two experimental conditions (the feeling trusted condition [n = 73] versus the control condition [n = 72]) and were subjected to the same manipulation and questionnaire as those defined in Study 1. In Study 3, we employed a multi-wave, multi-source design to test our full model in a field setting using a Chinese employee sample. At Time 1, the employees reported feeling trusted, perceived rarity of trust, psychological entitlement, and demographics. Approximately one week later (Time 2), their supervisors were invited to rate subordinates’ CWB. The final sample included 187 employees from 60 workgroups. The results of the studies revealed that feeling trusted positively influenced subordinates’ psychological entitlement, which in turn enhanced their subsequent CWB. Subordinates perceived rarity of trust moderated the effect of feeling trusted on psychological entitlement. Furthermore, subordinates perceived rarity of trust moderated the indirect effect of feeling trusted on CWB. That is, the positive indirect effect of feeling trusted on CWB via subordinates’ psychological entitlement was significant and positive when perceived rarity of trust was high and did not exist when perceived rarity of trust was low. This research makes several important contributions. First, we challenge the consensus regarding the universally positive effects of trust by suggesting that feeling trusted may have the potential to induce subordinates CWB. In doing so, this research provides a more dialectical perspective in understanding the effects of feeling trusted. Second, not only do we examine the potentially negative effects of feeling trusted, but we also examine when and why this effect unfolds. By exploring the dynamics of feeling trusted, we answer Bare et al.’s call for more research on feeling trusted. Finally, this research contributes to CWB literature by identifying an important but neglected antecedent of CWB in the workplace. We suggested that beyond leaders’ negative behaviors (e.g., abuse and injustice), their positive behaviors (i.e., expressed trust) may lead to subordinates’ CWB.

  • Trust is Valued in Proportion to Its Rarity? Investigating How and When Feeling Trusted Leads to Counterproductive Work Behavior

  • Spatial generalization of serial dependence in visual duration perception

    Subjects: Psychology >> Cognitive Psychology submitted time 2023-12-05

    Abstract: To establish a stable and sensitive experience of the world, the brain tends to use recent history when forming perceptual decisions. This results in serial dependence in perception, by which previous trials affect the current perception. The serial dependence effect can be divided into (at least) two categories: the effect of previous stimuli (i.e., the stimulus serial dependence effect) and the effect of previous decisions (i.e., the decisional serial dependence effect) on the current perception. Although separate stimulus and decisional serial dependence effects have been demonstrated in duration perception, their spatial selectivity is unclear. In the present study, we investigated whether and how serial dependence in duration perception generalizes across different visual positions of stimuli.
    The modified temporal bisection task was used in three experiments. Specifically, 24 naïve volunteers participated in Experiment 1. During the experiment, the visual stimulus (a white Gaussian blob) was pseudorandomly presented in the central or peripheral (10° from the left fixation) visual field. Participants were asked to judge whether the duration of the test stimulus (i.e., 300, 395, 520, 684, or 900 ms) was shorter or longer than a reference stimulus of intermediate duration (i.e., 520 ms) once the test stimulus disappeared. A group of 23 new volunteers were recruited for Experiment 2. The task of Experiment 2 was similar to that of Experiment 1, except that the visual stimulus was pseudorandomly located at either 5° to the left or 5° to the right of the central fixation. A new set of 24 volunteers participated in Experiment 3, in which the positions of both the fixation and the visual stimulus were changed; there were thus four types of positional relationships between stimuli across trials (i.e., identity, retinal position change, external position change, and both changes).
    The results showed that previous stimulus duration and previous choice exerted opposing effects on serial dependence of duration perception: specifically, a repulsive stimulus serial dependence and an attractive decisional serial dependence. In other words, current duration estimates were repelled away from the previous trial’s stimulus duration but attracted toward the previous choice. We found these effects in both the central and peripheral visual fields. More importantly, we found that the stimulus serial dependence effect was not constrained by the visual position of the stimuli: the effects were comparable between contexts in which the stimulus positions of previous and current trials were the same and when they were different. The effects fully transferred across the central and peripheral visual fields, across the left and right visual hemifields, and across different external spaces. However, we found that the decisional serial dependence effect was larger in the position-consistent context than in the position-inconsistent context. This indicates that the decisional serial dependence effect could only be partially transferred across different visual positions regardless of the types of positions (i.e., spatiotopic vs. retinotopic).
    These results provide evidence that both previous stimuli duration and previous choices affect subsequent perceptual decisions about duration, resulting in repulsive and attractive serial dependence effects, respectively. The repulsive stimulus serial dependence effect fully generalizes across different visual positions, suggesting it occurs primarily in higher-level visual areas. This also implies the existence of fast-duration adaptation. The attractive decisional serial dependence effect suggests that there is decision inertia in perceptual choices. Moreover, this effect is partly contingent on the visual position, which may result from the category organization function of higher-order brain areas. This suggests that the brain takes advantage of the visual position context when forming the decisional prior. These findings are helpful for understanding the plasticity of duration perception.
