知识操纵行为意向影响因素研究

知识（尤其是隐性知识）是员工生存和发展的关键资源，知识权利的不完全性决定了知识交换中不可避免地存在欺骗、偷盗、投机等失范行为。在协同创新过程中，知识型员工既相互合作又彼此竞争。除采取知识共享和知识隐藏两种策略外，员工通常会选择折中的、柔性知识操纵策略管理个体知识。由此，界定知识操纵内涵，剖析其自利性、欺骗性、不确定性和隐蔽性4个特点。在此基础上，选择扎根理论方法，通过对68名知识型员工访谈数据进行编码，构建由本体、主体、客体、载体、动机、环境、契合7个主范畴组成的知识操纵影响因素概念模型。最后，围绕知识操纵治理，提出优化创新任务属性、发挥知识操纵对象能动作用、选择高效知识管理载体、培养员工利他特质、营造协同创新环境、提高员工契合度等启示。

区域化党建视域下流动党员政党认同现状及提升途径研究--以宁波北仑为例

流动党员个体在政党认同强度上的差别，一定程度上影响着全党政治行为的整合性和驱动力。根据当前流动党员在政党认知、政党情感、政党评价及政党认同的行为四个层面的两面性分析，应从价值内化、情感维系、社会引导等三方面进行运作，以提高流动党员政党认同度。     

Does telic/paratelic user mode matter on the effectiveness of interactive internet advertising? A reversal theory perspective

Drawing on reversal theory (Apter, 2007), the current research proposes that internet users' metamotivational state (telic vs. paratelic) determines advertising interactivity's effectiveness. An online field experiment involving 141 Facebook and Twitter users tests this proposition. Research findings support telic state consumers form more positive attitudes toward a low-level interactive ad, whereas paratelic state consumers form more positive attitudes toward a high-level interactive ad. Further, this research shows that an arousal seeking tendency mediates the metamotivational state's impact on ad attitude.     

Forecasting market turbulence using regime-switching models

We propose an early warning system to timely forecast turbulence in the US stock market. In a first step, a Markov-switching model with two regimes (a calm market and a turbulent market) is developed. Based on the time series of the monthly returns of the S&P 500 price index, the corresponding filtered probabilities are successively estimated. In a second step, the turbulent phase of the model is further specified to distinguish between bullish and bearish trends. For comparison only, a Markov-switching model with three states (a calm market, a turbulent bullish market, and a turbulent bearish market) is examined as well. In a third step, logistic regression models are employed to forecast the filtered probabilities provided by the Markov-switching models. A major advantage of the presented modeling framework is the timely identification of the factors driving the different phases of the capital market. In a fourth step, the early warning system is applied to an asset management case study. The results show that explicit consideration of the models’ signals yields better portfolio performance and lower portfolio risk compared to standard buy-and-hold and constant proportion portfolio insurance strategies.     

试谈素质教育中实践能力的培养

素质教育的目的是全面贯彻党的教育方针,提高国民素质,培养学生的创造精神和实践能力。而实践能力是人的能力的重要成分,是学会做事的具体体现,是学生生存发展的需要。教育要注重知行统一,坚持教育教学与生产劳动、社会实践相结合,增强学生解决实际问题的本领和自主探究学习的能力。     

引入外资对银行风险承担的影响研究——基于我国153家商业银行的经验证据

文章基于中国153家商业银行2001-2017年的非平衡面板数据,采用双重差分模型研究了引入外资对银行风险承担的影响.实证结果表明:引入外资降低了中国商业银行的风险承担,外资股东发挥了积极的外溢效应和监督作用;外资持股比例与中国商业银行风险承担之间呈非线性的U型关系;引入外资影响中国商业银行的商业模式,引入外资的银行的非利息收入占比下降、非存款类负债占比上升,收入结构注重稳健且融资结构得到优化.上述研究结论的政策启示为:积极学习境外金融机构的先进知识和技术,建立可持续发展的合作伙伴关系;高度重视金融稳定,对外资进入中国银行体系实行分类管理;适度稳妥地推进中国银行业对外开放,把握好金融开放与金融安全之间的战略平衡.     

Seemingly inconsistent analyst revisions

In about 20%–30% of cases where an analyst revises two outputs (namely, earnings estimates, target prices, or stock recommendations) simultaneously, the two estimates are revised in opposite directions. Existing literature notes that these inconsistent outputs are widespread, and concludes that they are lower-quality, driven by strategic bias, and are viewed as less valid by investors. We find that these characterizations are generally inaccurate. Apparent inconsistency is largely driven by accounting and economic factors, with only limited evidence that investment banking-related conflicts play a role. Moreover, inconsistent outputs are neither less accurate than consistent outputs nor do they resolve less investor uncertainty upon their release. Overall, our results suggest that researchers should be cautious in interpreting the correlation between analyst outputs as a measure of bias or quality, and in using a single analyst output as a proxy for an analyst's overall views.     

人才培养目标与教学管理水平的关系整合——以高职土建类专业为例

高职土建类专业人才培养目标与教学管理有着密切的关系。教学管理对人才培养目标的实现产生多方面的影响,主要体现在目标管理、过程管理、绩效管理三个方面,在明确学生学习目标、激励学生学习动力、调动学生学习积极性、引导学生全面发展等方面具有举足轻重的作用。为了更好地实现人才培养目标,应实现教学管理重心从传统的过程管理向目标管理和绩效管理的根本性转变。     

On a general periodic preventive maintenance policy incorporating warranty contracts and system ageing losses

In this paper, a general periodic preventive maintenance (PM) policy for a repairable revenue-generating system is developed and studied. We define ‘ageing losses’ as the difference in revenues generated by an ideal system (no ageing) and a real system that ages over the same period of consideration. It is assumed that preventive maintenance slows the system deterioration process and therefore reduces ageing losses. The proposed model is general in the sense that (1) both the warranty contracts and system ageing losses are incorporated in the maintenance cost modeling and (2) the implementation of PM actions does not have to be strictly periodic. A cost model is developed for the buyer under two decision variables—the calendar time of the first PM and the degree of each PM. Numerical examples are then presented to show the effectiveness of the proposed model. Sensitivity analyses are further conducted to investigate the impact of model parameters on optimal solutions.
