畜禽空肠弯杆菌分离培养的影响因素

比较观察了空肠弯杆菌分离培养中微需氧法、培养时间、采样时机、运送时间、运送培养基、增菌培养法以及噻孢霉素和头孢哌酮钠等因素对该菌检出率的影响。结果表明 ,在 10 0mL/LCO2 气体环境中微需氧培养比烛缸内培养空肠弯杆菌检出率高 13 .0 % ,即显示 10 0mL/LCO2 法明显优于烛缸法 (P <0 .0 1) ;空肠弯杆菌分离培养时间以 48h即可 ,无须延长培养时间 ;产蛋鸡采样时机为产蛋前 ;检样运送时间、运送培养基和增菌培养后对空肠弯杆菌检出率的影响不明显(P >0 .0 5 ) ,用单一的一种分离培养方法不能反映动物的实际带菌水平 ;噻孢霉素对空肠弯杆菌检出率的影响和抗生素药敏性试验结果表明 ,噻孢霉素不能替代头孢霉素Ⅰ ,而头孢哌酮钠可取代Camp BAP琼脂中的头孢霉素Ⅰ。     

职务犯罪潜伏期刍议

职务犯罪潜伏期是指职务犯罪主体从实施职务犯罪行为即发案到案发的时间跨度。职务犯罪潜伏期增长速度之快、增长幅度之大，亟需关注。深入研究其原因，认清其危害，及时采取有效遏制对策，是惩治和预防职务犯罪中不容忽视的问题。     

Inside the black box of business incubation: Study B—scale assessment, model refinement, and incubation outcomes

Due to a lack of valid and reliable scales, few studies have sought to describe and measure the business incubation process. After rigorously developing and pre-testing scales intended to measure the incubation process (Study A), we collected data from 53 incubators operating in the US in order to (a) systematically examine the incubation process, and (b) validate the scales. Accordingly, this study offers (1) new, validated scales for measuring the process of incubating new ventures, (2) empirically-based refinements to a theoretical model of the incubation process, and (3) data on business incubation outcomes that are very useful for incubator planning and benchmarking purposes.

Are Service Profiles Incubator-Specific? Results from an Empirical Investigation in Italy*

What are the core services of start-up incubators, and how can the be managed best? We use five incubator archetypes (university, regional business, company-internal, independent commercial, and virtual incubators) to identify key services and describe their implementation. Case-research was conducted on 10 incubators (from an estimated total of 50) in Italy. We concluded that differences in competitive scope (industry, geography, and segment focus) and differences in strategic objectives (profit versus non-for-profit) influence the nature, quality and implementation of incubation services and the way they are managed.
