株洲冶炼厂电锌生产是采用沸腾焙烧、浸出、净化、电积、熔铸的湿法炼锌工艺。锌精矿焙烧的目的,除了使大部分硫化锌转变为氧化锌外,并根据过程的需要,补充在浸出系统中硫酸的损失,保留少部分硫呈硫酸盐形态,所以沸腾焙烧俗称酸化焙烧。在焙烧硫化锌精矿的过程中,产生大量的含SO_2及烟尘的 相似文献

Recent research on flexible office designs have shown that open‐plan and/or flex offices may not have the expected effects in terms of employees’ productivity, well‐being, job satisfaction, organizational commitment, and retention. In this article, we propose to consider that the feeling of de‐humanization may explain such dark side of office designs. Adopting a mixed methods approach, we administrated a quantitative survey to 534 employees working in a variety of office designs, and conducted 12 semi‐structured interviews among the respondents to the survey in order to investigate how they experienced their office designs, notably in terms of de‐humanization. Results showed that the three specific office designs under study (i.e. cell, open‐plan, and flex offices) are associated with different levels of de‐humanization and that this feeling of de‐humanization mediates their impact on employees’ job satisfaction, affective organizational commitment, extra‐role performance, psychological strains, and turnover intentions. Interviews’ analysis reveals three main mechanisms in the development of the feeling of de‐humanization in such office designs: a triple feeling of dispossession (of space, voice and professional mastery), a feeling of abandon and an injunction to adopt a modern behaviour. 相似文献

在市场经济环境中,公司制是企业选择的一种主流制式。在这一企业管理制式中,通过股东会、董事会、监事会、经理负责制的管理方式,充分利用出资人与经营者的私欲,促成双方责、权、利均衡;在完善的监督激励机制下,努力为公司工作成了实现各自私欲的唯一选择,极私成大公也许是阴极生阳的道家理论在企业管理中的具体应用吧。随着国企改革的深入,国有电力企业公司化改组正全面展开,在这一暂志过程中,由于出资人独特的身份 相似文献

We examine commercial office cap rates in 89 large cities in 33 developed and developing countries in the 2000–2019 period. We find that cap rates decline throughout the world over this period, reflecting a corresponding decline in the real rate of interest. In the cross-city analysis our most robust findings are that office cap rates are lower in wealthier cities, especially those that are either considered gateway cities or financial centers. In addition, cap rates tend to be higher in countries with lower credit ratings and higher inflation rates. We find that cap rates in suburban office markets are higher than in central business districts, and for a given metropolis, suburban cap rates are lower in suburbs with better public transport connections to the central business district. Finally, evidence from regressions with city fixed effects reveal that cap rates rise as the discount rate and vacancy rates increase and fall as cities get wealthier. 相似文献
