心理赋能视角下新生代员工工作投入行为研究——一个跨层中介模型

以我国新生代员工为研究对象,遵循"情境-认知-行为"分析框架,从心理赋能视角打开组织投入氛围对新生代员工行为影响的"黑箱",为有效提升新生代员工工作投入水平提供决策参考。通过对408名员工及其直接领导的配对取样,提出了一个跨层中介模型。研究发现:组织投入氛围越高,员工的个体工作投入水平越高;心理赋能作为一个整体构念,能够跨层部分中介组织投入氛围对员工个体工作投入的正向影响;心理赋能在跨层中介过程中起到显著中介作用的是自主性、效能感、工作意义维度,影响力维度没有起到中介作用。     

华北山前平原典型井灌区地下水水位变化影响因素分析

为定量评估华北山前平原多因子对地下水水位动态变化的影响,选取华北山前平原典型井灌区石家庄市栾城区为研究区,从水量平衡角度分析了影响该地区地下水水位动态变化的主要影响因子;利用主成分回归分析法排除主要影响因子间的相互作用,定量分析了各综合因子对地下水水位回升的贡献率;构建了栾城地下水水位主成分-时间序列模型预测多因子影响下的华北山前平原地下水水位变化。结果表明:1994—2015年栾城地下水水位主要受本地气候因子、本地人类活动和上游人类活动三方面影响因子的共同作用,各因子对当地地下水水位回升的贡献率分别为11.7%、-50.9%和-37.4%,对这三方面影响因子起主导作用的影响因素分别为栾城降水量、栾城小麦和玉米的种植面积以及上游石家庄市区人口;1994—2015年栾城自然气候变化有利于该地区地下水资源的恢复,但人类活动对地下水资源的影响仍占主导作用。     

当代问候语变迁的心理基础透视

Weathering Signals of Millennial-Scale Oscillations of the East-Asian Summer Monsoon over the Last 220 ka

This study generated a high-resolution paleoweathering record of the loess-soil sequence from the central Loess Plateau covering the last 220 ka using the ratio between the CBD (citrate-bicarbonate-dithionite) extractable free Fe_2O_3 (Fed) and total Fe_2O_3 (Fet). The new proxy shows a series of millennial oscillations, which are not necessarily documented by magnetic susceptibility from the same site. Because chemical weathering in the region depends mainly upon summer precipitation and temperature, we interpret these changes to be a result of millennial-scale variations in the strength of the East-Asian summer monsoon. Over the last glacial period, there is general agreement between the loess weathering record and the GRIP ice δ~(18)O record. The first suggests a rather stable summer monsoon pattern during the Last Interglacial period (marine δ~(18)O stage 5e). Large amplitude millennial oscillations of the summer monsoon seem to be particularly characteristic of the last glacial period whereas the fluctuations for the older periods are smoother.     

农业结构变动及其对农民收入影响的计量分析

用产业结构转换系数(即产业增长速度差异)和产业结构转换方向系数,定量分析了1978年以来农业产业结构转换的速度和趋势;并利用对数线性函数模型,定量分析了农业内部结构变动以及主要农产品产出结构的变动对农民收入增长的影响,分析了我国人均收入增长迟缓的原因,总结了我国农业结构调整的特点及存在的问题。图1,表1,参6。     

Butterflies (Lepidoptera: Papilionoidea) of Mount Kilimanjaro: Nymphalidae subfamilies Libytheinae,Danainae, Satyrinae and Charaxinae

This paper, which presents an annotated checklist of the ‘lower Nymphalidae’ (Libytheinae, Danainae, Satyrinae, Charaxinae), is the fourth in a series on the butterfly fauna of Mount Kilimanjaro. Four genera of lower Nymphalidae (Danaus, Amauris, Bicyclus, Charaxes), with a total of 11 included species, are known or believed to occur within the main forest zone, from c. 1800 to 2800 m. Of these, only three species of Charaxes (Charaxes berkeleyi, Charaxes ansorgei, Charaxes xiphares) may be restricted locally to this primary forest. The lower slopes fauna, below 1800 m, is considerably richer, with a total of 11 genera and 41 species listed (8 species of which extend into the forest zone). Possible additional species, dubious earlier records, problems with African subspecies of Danaus chrysippus, a need for more work on certain Satyrinae, and classification of the genus Charaxes are discussed. An identification key to the subfamilies of Nymphalidae, and the 19 genera of Libytheinae, Danainae, Satyrinae, Charaxinae that occur in Tanzania, together with a key to the adults of all the species of these four subfamilies considered to occur or have occurred on Kilimanjaro, with 206 colour images, are included as online Supplementary Information.     

Butterflies (Lepidoptera: Papilionoidea) of Mount Kilimanjaro: introduction and family Papilionidae

This article marks the beginning of a short series on the butterfly fauna of Mount Kilimanjaro. It commences with a brief overview of the topography, tectonic history, climate, ecological zonation and conservation significance of Africa's highest mountain. Following an introductory account to the butterfly fauna, the rest of this paper presents an annotated checklist of the swallowtails (Papilionidae). Eight papilionid species are currently believed to occur within the main forest zone, from 1800 to 2800 m (in places this zone extends down to c.1600 m). Another 10 have been recorded from the lower slopes, which include some disturbed forest and forest relicts, from 700–1800 m. The need for better data is discussed in light of the suggestion that the butterflies of Mount Kilimanjaro could become a focal group for monitoring effects of climate change. An identification key to families, together with a key to the swallowtail species and colour illustrations of adults, are included as online Supplementary Information.
