现代企业制度与企业档案工作

现代企业制度是法人企业制度,其主要形式是公司制。公司制企业以清晰的产权关系为基础,以完善的法人制度为核心,以有限责任制度为主要特点。“产权清晰,权责明确,政企分开,管理科学”是现代企业制度的基本内容。而企业档案是企业职工集体智慧的结晶,是企业建设与发展的真实历史记录,有成功经验总结,也有失败的教训归纳。毫无疑义,它是知识,是财富,是企业重要的无形资产。可以说,

当前企业档案工作面临的问题及对策

现在企业的改革正向着以“产权明晰,权责明确,政企分开,管理科学”为核心的现代企业制度方向发展,这将促使企业在管理、机制上发生巨大的变化。企业档案是企业活动的记录和凭证,是企业生产、经营、科研和发展的必备条件。企业档案工作作为企业管理基础工作的组成部分,怎样适应现代企业制度,更好地为企业的经济建设服务呢？一、企业推行现代企业制度后,档案工作面临的问题深化国有企业改革的重点在于政企分开,政府不直接干预企业正常的生产经营活动,只对企业拥有监督、协调和管制的权利。这样企业就有了更多的自主权,可以从本身的…     

Kinetics Inside,Outside and Through Cucurbiturils

This review describes the kinetics at play in Cucurbituril (CB[n])/guest recognition within a very wide time frame, from picoseconds to days. We cover the kinetics of (1) radiative and non-radiative decays of fluorophores inside and outside CB[n]s, (2) guest motions in the CB[n] cavity, and (3) ingression, egression and threading mechanisms into, out of and through the macrocycles. We then show that the kinetics of guest release or capture can be controlled using CB[n]-capped mesoporous systems and micelles, or by coupling those processes to the kinetics of ancillary reactions. The last section is devoted to the latest examples of reactions catalyzed and inhibited by CB[n]s.

Size-Resolved Concentrations of Particulate Matter and Bioaerosols Inside versus Outside of Homes

Size-resolved airborne particulate matter samples (PM _2.5 , PM ₁₀ , and TSP) collected inside ten northern California homes over four days and one night (9–12 h/sample, spanning a 3.5 week period) were analyzed for protein, endotoxin, and (1 → 3)-β-D-glucan concentrations. Some simultaneous size-resolved outdoor samples were also collected. The associations of residential characteristics and occupant behavior with the indoor airborne levels were investigated. In addition, the relation between these chemical biomarkers and the more traditional culturing approaches was studied. Most of the indoor mass concentration of airborne particles and protein was in the fine fraction (PM _2.5 ), while the mass of airborne endotoxin and (1 → 3)-β-D-glucan was mainly in the coarser fractions (PM _10–2.5 and PM _TSP–10 ). No strong correlations were seen between short-term (3–6 min) culturable bacteria and fungi counts and the corresponding longer-term (9–12 h) biomarker levels. Daytime indoor levels of the biomarkers tended to be higher than outdoors, especially for the PM _10–2.5 fraction, but only in a few cases were the indoor/outdoor relationships statistically significant. Indoor pets were associated with elevated airborne PM and bioaerosols inside homes. Two other factors, wall-to-wall carpet and older houses, also appear to be associated with some elevations in indoor levels.

The Distinct Properties of the Consecutive Disordered Regions Inside or Outside Protein Domains and Their Functional Significance

The consecutive disordered regions (CDRs) are the basis for the formation of intrinsically disordered proteins, which contribute to various biological functions and increasing organism complexity. Previous studies have revealed that CDRs may be present inside or outside protein domains, but a comprehensive analysis of the property differences between these two types of CDRs and the proteins containing them is lacking. In this study, we investigated this issue from three viewpoints. Firstly, we found that in-domain CDRs are more hydrophilic and stable but have less stickiness and fewer post-translational modification sites compared with out-domain CDRs. Secondly, at the protein level, we found that proteins with only in-domain CDRs originated late, evolved rapidly, and had weak functional constraints, compared with the other two types of CDR-containing proteins. Proteins with only in-domain CDRs tend to be expressed spatiotemporal specifically, but they tend to have higher abundance and are more stable. Thirdly, we screened the CDR-containing protein domains that have a strong correlation with organism complexity. The CDR-containing domains tend to be evolutionarily young, or they changed from a domain without CDR to a CDR-containing domain during evolution. These results provide valuable new insights about the evolution and function of CDRs and protein domains.
