探讨饲料企业管理中激励机制模式创新

随着饲料企业逐步向专业化、集约化、规范化方向转变,人力要素已逐渐取代生产物质要素成为企业市场竞争力的核心要素,这就意味着现代化企业管理制度与人才激励机制已成为饲料企业体系中必须建立的环节。本文在探讨激励机制内涵与我国饲料企业管理中激励机制体系建立意义的基础上,审视了目前饲料企业激励机制模式的发展现状,并针对这一现状从企业的薪酬福利制度、大数据应用及精神激励机制的建构等角度来思考激励机制的创新路径,让激励机制在饲料企业管理中更好地发挥自身价值。     

Thermal biology and locomotor performance in Phymaturus calcogaster: are Patagonian lizards vulnerable to climate change?

Behavioral and physiological traits of ectotherms are especially sensitive to fluctuations of environmental temperature. In particular, niche-specialist lizards are dependent on their physiological plasticity to adjust to changing environmental conditions. Lizards of the genus Phymaturus are viviparous, mainly herbivorous, and inhabit only rock promontories in the steppe environments of Patagonia and the Andes. Herein, we examine the vulnerability of the southernmost Phymaturus species to global warming: the endemic Phymaturus calcogaster, which lives in a mesic environment in eastern Patagonia. We studied body temperatures in the field (T_b), preferred body temperatures in a thermogradient (T_pref), the operative (T_e) and environmental temperatures, and the dependence of running performance on body temperature. P. calcogaster had a mean T_b (27.04°C) and a mean T_e (31.15°C) both lower than their preferred temperature (T_pref = 36.61°C) and the optimal temperature for running performance (T_o = 37.13°C). Lizard activity seems to be restraint during the early afternoon due high environmental temperatures. However, both, the high safety margin and warming tolerance suggest that the expected increase in environmental temperatures due to global warming (IPCC report in 2018) would not threaten, but indeed enhance locomotor performance in this population.     

基于层次分析法的辽河干流水环境承载力评价研究

目前,水生态文明建设提出后,水环境承载力成为衡量地区可持续发展能力的一项重要指标。为了解辽河干流沿岸城市的水环境承载状况,以辽河干流为研究区域,采用层次分析法,建立以水资源、社会、经济、生态环境为子系统的评价体系。代入各行政分区的样本值,进行辽河干流水环境综合承载能力计算。评价了各行政分区不同现状年的承载状况。

渗灌对日光温室番茄栽培环境的影响

研究了渗灌和漫灌对日光温室番茄栽培环境及番茄产量的影响。结果表明,渗灌下,土壤密度比漫灌低7.59%,差异极显著;土壤总孔隙度比漫灌高9.72%,差异显著;土壤黏粒和粉粒高于漫灌,而砂粒和细粗砾低于漫灌;观测时段内,渗灌下平均气温、10cm处土壤平均温度较漫灌分别高1.55℃、0.86℃,地表平均温度比漫灌低0.14℃;渗灌下温室空气相对湿度较漫灌低11.86%,以10:00—20:00差值最大;渗灌下番茄产量比漫灌高8.60%,且差异显著。     

Study on Fans Cooling of Dairy Cowshed with Free Stall in Northern Mountainous Region of Hebei in Summer

The present objective of the study was to investigate the effect of fans cooling on dairy cow in northern mountainous region of Hebei in summer.Two cowsheds with the same structure and feeding technics were used to investigate the effect of fans on indoor temperature and humidity, physiological parameters and milking performance of dairy cow.The results showed that the average ambient temperature in cowshed with fans was 1.5℃ lower than that of the control cowshed, and the average wind velocity was 0.49 m/s higher than that of the control cowshed, reaching to 0.66 m/s.Temperature-humidity index (THI) of cowshed with fans was significantly lower than that of the control shed during the period of fans running (P<0.05).Besides, the rectal temperature and respiration rate of dairy cows in cowshed with fans were significantly lower than of the control cowshed (P<0.05), and the milk yield per cow per day was 17.0% higher than that of the control cowshed (P<0.05), however, the milk fat, milk protein and milk sugar were no significant difference from the control (P>0.05).Overall, fans could decrease indoor environment, moderate heat stress and increase performance and health of dairy cows in northern mountainous region of Hebei.     

论思维创新活动的自组织性

从知识社会学意义来看,思维创新活动的社会化过程存在着三个阶段。在潜思维创新阶段存在着社会思维系统内部由新质差别所引起的对常规思维平衡态的偏离即微观涨落。在趋显思维创新阶段,这种思维创新的微观涨落由于处在远离常规思维平衡态的非线性区域而不断得以放大与扩展,形成创新思维"巨涨落",从而推动着创新思维自身系统向新的有序化创新思维系统结构演进。在显思维创新阶段,各种思维创新主体及其思维知识信息相互融合和协同,在新的层次上形成了以新的思维范式为核心的社会创新思维有序化结构即社会创新思维耗散性结构。
