Desire satisfaction,death, and time

Desire satisfaction theories of well-being and deprivationism about the badness of death face similar problems: desire satisfaction theories have trouble locating the time when the satisfaction of a future or past-directed desire benefits a person; deprivationism has trouble locating a time when death is bad for a person. I argue that desire satisfaction theorists and deprivation theorists can address their respective timing problems by accepting fusionism, the view that some events benefit or harm individuals only at fusions of moments in time. Fusionism improves on existing solutions to the timing problem for deprivationism because it locates death’s badness at the same time as both the victim of death and death itself, and it accounts for all of the ways that death is bad for a person. Fusionism improves on existing solutions to the problem of temporally locating the benefit of future and past-directed desires because it respects several attractive principles, including the view that the intrinsic value of a time for someone is determined solely by states of affairs that obtain at that time and the view that intrinsically beneficial events benefit a person when they occur.     

Personal attitudes toward time: The relationship between temporal focus,space‐time mappings and real life experiences

What influences how people implicitly associate “past” and “future” with “front” and “back?” Whereas previous research has shown that cultural attitudes toward time play a role in modulating space‐time mappings in people's mental models (de la Fuente, Santiago, Román, Dumitrache & Casasanto, 2014), we investigated real life experiences as potential additional influences on these implicit associations. Participants within the same single culture, who are engaged in different intermediate‐term educational experiences (Study 1), long‐term living experiences (Study 2), and short‐term visiting experiences (Study 3), showed their distinct differences in temporal focus, thereby influencing their implicit spatializations of time. Results across samples suggest that personal attitudes toward time related to real life experiences may influence people's space‐time mappings. The findings we report on shed further light on the high flexibility of human conceptualization system. While culture may exert an important influence on temporal focus, a person's conceptualization of time may be attributed to a culmination of factors.     

A wearable vibrotactile biofeedback system improves balance control of healthy young adults following perturbations from quiet stance

Maintaining postural equilibrium requires fast reactions and constant adjustments of the center of mass (CoM) position to prevent falls, especially when there is a sudden perturbation of the support surface. During this study, a newly developed wearable feedback system provided immediate vibrotactile clues to users based on plantar force measurement, in an attempt to reduce reaction time and CoM displacement in response to a perturbation of the floor. Ten healthy young adults participated in this study. They stood on a support surface, which suddenly moved in one of four horizontal directions (forward, backward, left and right), with the biofeedback system turned on or off. The testing sequence of the four perturbation directions and the two system conditions (turned on or off) was randomized. The resulting reaction time and CoM displacement were analysed. Results showed that the vibrotactile feedback system significantly improved balance control during translational perturbations. The positive results of this preliminary study highlight the potential of a plantar force measurement based biofeedback system in improving balance under perturbations of the support surface. Future system optimizations could facilitate its application in fall prevention in real life conditions, such as standing in buses or trains that suddenly decelerate or accelerate.     

Self-Affection and Pure Intuition in Kant

Are the pure intuitions of space and time, for Kant, dependent upon the understanding's activity? This paper defends the recently popular Self-Affection Thesis (SAT): namely, that the pure intuitions require an activity of self-affection—an influence of the understanding on the inner sense. Two systematic objections to this thesis have been raised: The Independence objection claims that SAT undermines the independence of sensibility; the Compatibility objection claims that certain features of space and time are incompatible with being the products of the understanding's activity. I show that the resources to rebut these objections can be found in Kant's account of causal influence.     

Person‐specific versus multilevel autoregressive models: Accuracy in parameter estimates at the population and individual levels

This paper compares the multilevel modelling (MLM) approach and the person‐specific (PS) modelling approach in examining autoregressive (AR) relations with intensive longitudinal data. Two simulation studies are conducted to examine the influences of sample heterogeneity, time series length, sample size, and distribution of individual level AR coefficients on the accuracy of AR estimates, both at the population level and at the individual level. It is found that MLM generally outperforms the PS approach under two conditions: when the sample has a homogeneous AR pattern, namely, when all individuals in the sample are characterized by AR processes with the same order; and when the sample has heterogeneous AR patterns, but a multilevel model with a sufficiently high order (i.e., an order equal to or higher than the maximum order of individual AR patterns in the sample) is fitted and successfully converges. If a lower‐order multilevel model is chosen for heterogeneous samples, the higher‐order lagged effects are misrepresented, resulting in bias at the population level and larger prediction errors at the individual level. In these cases, the PS approach is preferable, given sufficient measurement occasions (T ≥ 50). In addition, sample size and distribution of individual level AR coefficients do not have a large impact on the results. Implications of these findings on model selection and research design are discussed.     

破解“通勤悖论”:通勤时间如何影响幸福感

本文从社会过渡带和心理过渡带两个方面对"通勤悖论"进行解析,构建了通勤时间影响幸福感的理论模型。通过对广州市白领的追踪调查和多项式回归分析,结果发现:(1)婚姻状态(社会过渡带)具有调节作用,未婚员工通勤时间负向影响生活满意度,已婚员工通勤时间对生活满意度和快乐度有曲线影响;(2)恢复体验(心理过渡带)具有交互效应,心理解脱调节了未婚员工通勤时间与通勤效用的关系,放松体验调节了未婚员工通勤时间与快乐度的关系;(3)已婚员工通勤时间与通勤效用和快乐度的关系受放松体验调节,与生活满意度的关系受心理解脱调节;(4)通勤时间对生活满意度和快乐度的影响,以及婚姻状态和恢复体验的交互效应,以通勤效用为中介;(5)员工在"通勤时间陷阱"(1.75~2.75小时)的效用均衡。结论有助于分析"通勤悖论"的深层原因,对城市管理、企业管理和个人都具有积极启示。     

时间压力的双刃效应及其作用机制

时间压力是现代社会中人们经常面对的重要问题。以往研究认为时间压力只会产生消极影响, 然而现有研究发现时间压力也会产生积极影响。总结以往研究, 介绍了时间压力的概念和测量方式, 分别阐述了时间压力的损耗作用和促进作用, 并用注意焦点理论、激活理论、维生素模型和挑战?阻碍模型等理论解释时间压力的双刃效应。未来研究应该进一步关注：(1)基于时间心理账户开展时间压力的分类研究; (2)时间压力促进作用的动机和情绪双路径机制; (3)探寻有效缓解时间压力损耗作用的机制。     

临床医学类学术论文应正确使用“随机化”
