Across the Martian Frontier? Thoughts on Planet B,a Martian Safety Valve,and the Earth as Our Body

Even though we are on the precipice of a “bad Anthropocene,” humankind should not colonize Mars. Mars is often depicted as our “Planet B”—an evacuation plan for Earth. But in this time of ecological crisis, theologian Sallie McFague suggests that we think of the Earth as God’s body and take our obligation to care for our common home seriously. Likewise, in contrast to calls for colonization, I contend that two American historical anecdotes—the safety valve theory and the Yellowstone—illustrate why humanity should think less about becoming Martians and instead find meaning and purpose in remaining Earthlings.     

心理资本: 本土量表的开发及中西比较

开发了本土心理资本量表, 并将之与西方量表进行了比较。结果显示, 本土心理资本构念具有二阶双因素结构: 事务型心理资本(自信勇敢、乐观希望、奋发进取与坚韧顽强)与人际型心理资本(谦虚诚稳、包容宽恕、尊敬礼让与感恩奉献)。事务型心理资本与西方心理资本基本相似, 人际型心理资本则具有本土文化气息。本土量表具有良好的效标关联效度, 人际型心理资本、事务型心理资本和任务绩效、周边绩效、工作满意度、工作投入及组织承诺显著正相关, 人际型心理资本与传统性、相依我正向关系显著。相比西方量表, 本土量表的信效度更好, 对工作绩效有更强的解释能力, 尤其是对周边绩效。建议进行心理资本研究时应充分考虑中西文化差异, 对组织而言, 则应重视对雇员本土心理资本各要素的开发与管理。     

正念减压疗法在护士职业倦怠干预中的应用

在当前的医疗和社会环境下,护士群体面临着巨大的压力,承受着职业枯竭困扰。针对国内护士职业倦怠干预研究的现状,着重介绍了西方临床心理学界广泛应用的正念减压疗法(mindfulness-based stress reduction,MBSR)及其在压力管理和身心疾病的康复等方面的积极疗效。根据正念减压疗法的特点、作用机制和其与护理理论的关系,探讨这种训练应用于护士职业倦怠预防和干预的合理性。     

赢者诅咒：心理机制、影响因素及应对策略

赢者诅咒是指在拍卖情境中, 竞价者为了获得拍卖品会过高估计其价值, 竞价成功以后当他发现其价值和自己之前的期望不一致时所产生的一种“诅咒”心理。赢者诅咒现象普遍存在于企业的资产拍卖、兼并重组、博彩游戏、投资决策等领域。损失规避和过度自信理论是赢者诅咒的主要心理机制, 而其影响因素主要有竞拍商品价值的不确定性、竞价人数、信息因素和竞价经验等。赢者诅咒的应对策略主要包括联合竞标、信息共享和学习。未来对赢者诅咒的研究需要进一步探讨赢者诅咒的心理机制、研究范式及本土化等问题。     

配偶的善意性别偏见对职业女性工作繁荣的影响机制研究：一个有调节的中介模型

本文基于工作-家庭资源模型,采用问卷调查法,收集208份双职工夫妻配对数据,探讨配偶的善意性别偏见对职业女性工作繁荣的中介机制与边界效应。研究结果表明：配偶的善意性别偏见负向预测职业女性的工作繁荣,家庭-工作冲突中介了配偶的善意性别偏见与工作繁荣的关系;同时,职业女性的工作中心性调节了家庭-工作冲突在二者间的中介作用。研究结果对降低职业女性的家庭-工作冲突,减少善意性别偏见,促进工作繁荣有一定的理论和实践意义。     

Consciously monitored grasping is vulnerable to perceptual intrusions

The idea of functional differentiation between vision-for-action and vision-for-perception has been supported by evidence from different domains. According to this account, perception is based on consciously accessible, relative representations, whereas vision-for-action is performed in an analytic, automatic manner. Support for this idea comes from studies that showed that unlike perception, grasping movements are refractory to illusions and to Weber’s law. Yet, interactions between the systems may occur when an action is performed in a less automated fashion. To test this idea, we asked participants to monitor their fingers apertures in flight and to halt their movement for a short duration when they felt that their aperture reached a maximum amount. The results showed that movements in the monitored condition were biased by the Ponzo illusion and showed atypical adherence to Weber's law. These results show that action and perception are more likely to interact when movements are performed in a controlled manner.     

Differences in cognitive performance between informal caregivers and non-caregivers

ABSTRACT

Extensive literature exists documenting the relationship between stress and cognition. Caregiving for an individual with Alzheimer’s disease can be aunique and chronic stress experience due to the increasing dependency of the care-recipient as the disease progresses. The current study examines the relationship between stress and cognitive performance in 47 dementia caregivers compared to 47 noncaregiver control participants matched on age, gender, and education. Participants completed measures assessing stress (measured via the Perceived Stress Scale) and seven domains of cognition including episodic memory, working memory, executive functioning, attention, visuospatial processing, processing speed, and implicit memory. Results showed that caregivers had poorer performance than non-caregivers on certain measures of episodic memory, working memory, and executive functioning; while no significant differences were observed on measures of attention, visuospatial processing, processing speed, or implicit memory. In addition, when controlling for general stress, caregiver performance on measures of processing speed and visuospatial processing was also poorer than non-caregivers. By controlling for levels of general stress that may not be related to caregiving, these results show that differences in cognitive performance are unlikely to be explained by general stress alone.     

Re-reading Anscombe on ‘I’

According to a ‘Straight’ reading of Elizabeth Anscombe’s (1975 Anscombe, E. 1975. “The First Person.” In her Mind and Language, edited by S. Guttenplan, 45–65. Oxford: Oxford University Press. [Google Scholar]) ‘The First Person’, she holds a radically non-referring view of ‘I’. Specifically, ‘I’ is analogous to the expletive ‘it’ in ‘It’s raining’. I argue that this is not her conclusion. Her substantive view, rather is that if what you mean by ‘reference’ is a certain rich and recherché notion tracing to Frege, then ‘I’ is not a referring term. Her methodological point is that one shouldn’t be ‘bewitched by language’ into thinking that ‘I’, because of its syntax, must exhibit ‘reference’ in this sense.
