政府信息共享障碍及一个微观解释

本文对政府信息来源及其管理经费进行分析，认为公众与政府信息机构的委托代理关系决定了政府信息共享本质属性与必然障碍。在对四个方面的主要障碍进行详细分析之后，运用一个数学模型解释了政府信息共享障碍的根本原因在于存在信息租金，解决这个问题需要在政府信息机构的体制改革中适度引入市场机制并建立相应的法律保障。

微信用户后悔情绪影响因素与应对策略选择——基于SEM与fsQCA的研究

[目的/意义] 随着社交媒体应用的迅速普及和持续渗透,众多社交媒体用户面临过度使用问题,其正常的学习、工作和生活受到干扰,引发了用户焦虑、倦怠与后悔等负面情绪。探究引发用户后悔情绪的影响因素与应对策略的选择问题对社交媒体服务商缓解用户负面情绪、提高用户忠诚度,并促进用户健康使用社交媒体具有重要意义。[方法/过程] 以微信用户为研究对象,从社交过载、信息过载和系统功能过载视角出发,考虑用户转换成本与自我情绪管理的影响,构建微信用户过度使用的后悔情绪影响因素及其应对策略模型,采用结构方程模型（SEM）与模糊集定性比较分析（fsQCA）相结合的方法进行分析。[结果/结论] ①微信用户涉入程度正向影响用户对社交过载、信息过载和系统功能过载的感知及其转换成本,进而加剧用户的后悔情绪;②用户的后悔情绪越强烈、面临的转换成本越高,则越倾向于采取情绪导向应对策略,其次是问题导向应对策略;③微信用户自我情绪管理水平越高,用户越可能采取合适的应对策略以缓解自身后悔情绪;④定性比较分析发现两类触发微信用户后悔情绪的前因构型、四类触发问题导向应对策略选择的前因构型和一类触发情绪导向应对的前因构型。

Relationship between hyperuricemia and metabolic syndrome

Objective: To investigate the relationship between metabolic syndrome and hyperuricemia. Methods: A total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as ≥7 mg/dl (in men) or ≥6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. Results: (1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia odds ratio (OR)=1.634, P=0.000. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia. Conclusion: Hyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome.     

A rapid and accurate 3-（4,5-dimethyl thiazol-2-yl）-2,5-diphenyl tetrazolium bromide colorimetric assay for quantification of bacteriocins with nisin as an example

The objective of this study is to propose a more accurate and faster MTT 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide colorimetric assay (MCA) for quantitative measurement of polypeptide bacteriocins in solutions with nisin as an example. After an initial incubation of nisin and indicator bacterium Micrococcus luteus NCIB 8166 in tubes, MTT was added for another incubation period. After that, nisin was quantified by estimating the number of viable bacteria based on measuring the amount of purple formazan produced by cleavage of yellow tetrazolium salt MTT. Then MCA was compared to a standard agar diffusion assay (ADA). The results suggested a high correlation coefficient (r2=0.975±0.004) between optical density (OD) and the inhibitory effect of nisin on a bacterial strain Micrococcus luteus NCIB 8166 at a range of 0.125～32 IU/ml. The MCA described in this study was very quick. Quantification of nisin took only 7～8 h and the detection limit was at the level of 0.125 IU/ml when compared to 12 IU/ml and 24～28 h for ADA. The MCA provides an accurate and rapid method for quantifi-cation of nisin in solutions and is expected to be used for quantification of other antimicrobial substances.     

陀思妥耶夫斯基的“神人”论

陀思妥耶夫斯基一生关注"人"的问题,力求在"人身上发现人"。他在人和神之间建立亲密相通的关系,肯定"神人",否定"人神",认为只有具有基督般美德的"神人"才能拯救世界。他的神人拯救理论,虽然是为道德信仰寻求神学上的论证,却彰显了道德在历史中的作用。
