Do 5% changes around maximal lactate steady state lead to swimming biophysical modifications?

Our purpose was to examine the swimming biophysical responses at velocities (v) of 97.5, 100 and 102.5% of the maximal lactate steady state (MLSS). Ten elite female swimmers performed three-to-five 30-min constant tests at imposed paces to determine 97.5, 100 and 102.5%MLSS v. Gas exchange, blood lactate concentration ([La-]), stroke rate (SR) and v were determined during each test. The v values at 97.5, 100 and 102.5%MLSS were 1.21 ± 0.07, 1.24 ± 0.07 and 1.27 ± 0.07 m.s⁻¹, respectively. Oxygen uptake (V̇O₂) and Pulmonary ventilation (V̇E) increased as function of v. SR and stroke length (v/SR = SL) increased as a function of v. All measured variables were constant as a function of time at 97.5%MLSS and 100%MLSS. At 102.5%MLSS SR increased (3.5%) and stroke length (SL) decreased (3.5%) as a function of time. While V̇O₂ was constant at 102.5%MLSS, [La-] and V̇E increased as a function of time, suggesting hyperventilation, at v’s of 97.5%MLSS and 100%MLSS swimmers completed the 30 min swim in spite of decreased SL and increased SR. However, the decrease in SL and increased SF were accompanied by increased [La-] and V̇E and resulted in the inability of most swimmers to complete the 30 min swim presumably due to fatigue at 102.5%MLSS.     

Asymmetries between victims' and transgressors' perspectives following interpersonal transgressions

When interpersonal transgressions occur, the involved parties try to understand what occurred and how justice should be restored. However, research has documented that victims and transgressors often diverge in their accounts of what transpired. In this paper, I review and summarize empirical research on victims' and transgressors' asymmetric perceptions of interpersonal transgressions and the different justice‐restoring responses each party subsequently desires. By conceptualizing transgressions in terms of the social roles of victim and transgressor, I contend that justice responses can be thought of as attempts to correct inequitable distributions of material and symbolic resources. This social exchange perspective enables us to understand each party's motives and how various justice responses might satisfy them. I argue that because of these asymmetric perspectives, reconciliation is difficult, and conflict is liable to be perpetuated rather than resolved.     

从社会交换的角度看组织认同的来源及效益

从社会交换的角度探讨了组织认同的来源及效益。采用结构方程建模的方法,通过对398名企业个体的问卷调查所获取的数据进行分析,结果表明：（1）POS对组织认同和留职意愿有着直接的显著影响;同时,它通过组织认同的中介作用对个体的留职意愿、同事间利他行为、个人主动性、人际和谐和保护公司资源会产生间接的影响;（2）LMX对组织认同和留职意愿没有直接的显著影响;但它对同事间利他行为、个人主动性、人际和谐和保护公司资源有着直接的显著影响     

西方有关择偶启事的研究和论争

文章梳理了自20世纪70年代至本世纪初,西方以择偶启事为研究蓝本的择偶标准与择偶策略研究,展示了西方研究者运用进化心理学理论、社会学习理论与社会交换理论,对一般异性恋择偶,择偶启事回复率、初婚和再婚人士择偶,同性恋、异性恋、双性恋择偶间比较,以及网络启事择偶几方面的研究历程;预测了未来择偶启事研究的趋势应是几种理论间观点的相互借鉴与整合     

Preferences for token exchange‐production schedules: Effects of task difficulty and token‐production schedules

Previous research suggests that accumulated exchange‐production schedules promote increased work completion and are more preferred than distributed exchange‐production schedules. The purpose of this study was to evaluate whether the response effort or token‐production schedules associated with token delivery influenced preferences for exchange‐production schedules. Tokens exchanged under accumulated schedules were more preferred, relative to distributed schedules, when tokens were earned for completing easy tasks. When participants earned tokens for completing difficult tasks, two of three participants preferred accumulated exchange‐production schedules (Experiment 1). Under dense token‐production schedules, accumulated exchange‐production schedules were preferred, but participant's preferences switched to distributed schedules under increasing token‐production (i.e., leaner) schedules (Experiment 2).     

The glow of Telesphoros: a brief enquiry into the sense of the term ‘mana personality’ and the dynamic of experiences behind it

In this article, I begin by outlining the qualities and attributes associated with experiences of mana, focusing particularly on the way the term ‘mana’ was used by C.G. Jung in his published work. I note that Jung associated mana with the accumulation and transfer of psychic energy (libido), with the appearance and appropriation of elemental fire, and by extension, with the metamorphic experience of constellating consciousness. In this context, informed by Jung’s accounts and modes of expression, the term mana personality becomes a provisional designation for a recurrent dynamic of archetypal experiential configurations whose telos appears to be the reorientation of consciousness to its origin.     

预测加工：走出两代认知科学的历史僵局

表征-计算观与具身行动观对认知的本质几乎做了截然相反的强调。近年来,预测加工理论的发展为统一两代认知科学提供了契机。预测加工是层级预测加工与主动预测加工这两大理论部件的合称,前一部件主要继承了第一代认知科学中的层级计算加工进路,后一部件则发扬了第二代认知科学中与行动有关的理论,这两大理论部件被视为同一个统一整合理论的两个不同方面。在当代,预测加工被认为有望成为未来认知科学的新范式。     

行为博弈与社会交换

行为博弈与社会交换看似两个毫无关联的现象和研究领域,却有着内在的、实质性的联系。行为博弈也是一种社会交换或以社会交换为机制,社会交换则表现为一种行为博弈或有着内在的博弈性质。行为博弈与社会交换互为表里、互为机制、水乳交融,行为博弈是社会交换的行为博弈,社会交换是行为博弈的社会交换。以行为博弈的眼光来看待社会交换或以社会交换的意识来研究行为博弈,跨领域的研究洞视,各自互为对方启动了一方别开生面的研究天地,为枯燥乏味的传统博弈研究和死水微澜的社会交换领域凭添了一丝新鲜气息。     

上下级情绪智力对LMX、员工工作结果变量的作用研究

本研究探讨员工情绪智力对领导一成员交换（LMX）和员工工作结果变量的影响,并分析了上级情绪智力在其间的作用。研究通过对银行业员工及其直接领导进行280份问卷调查,运用相关分析、回归分析等统计方法。发现员工情绪智力和LMX、员工的情感承诺、组织公民行为、工作绩效正相关,上级情绪智力对员工情绪智力和LMX之间的关系有缓冲作用,LMX对员工情绪智力和员工情感承诺、组织公民行为之间的关系起到部分中介作用。
