再谈篆刻章法的形式构成美

文章通过对历代篆刻名作章法的分析来探究篆刻章法的形式构成规律,认为篆刻章法的形式构成美是历代篆刻家不断积累起来的审美经验在印面上的表达,篆刻章法的形式构成关键就在于对形式美法则的灵活运用。     

秦简“当腾腾”音义商兑

“当腾腾”是里耶秦简、睡虎地秦简中的一个公文习语,李学勤、胡平生等众多学者的释读皆存疑问。考诸古音通假及秦代避讳之实,“腾”当通“朕”,可训为“封”,“当腾腾”意即“该封,封”。“天子自称曰朕”始于嬴正廿六年,秦汉讳“朕”,有《说文》为证,但古今学人均未尝言及。     

论网络消极口碑传播心理影响因素

随着网络技术的迅速发展,网民数量的激增,网络舆论已成为一股不可忽视的力量。网络舆论中的消极口碑的传播变得更快和更具有影响力,对网络消极口碑的传播进行研究也显得越来越重要。文章分析了网络消极口碑传播国内外的研究现状,并提出影响网络消极口碑传播的八大心理因素。     

顾客抱怨处理公平性对口碑传播意愿的影响研究——以零售企业为例

基于公平性理论,在对顾客抱怨处理和口碑传播意愿理论归纳和阐述的基础上,设计调查问卷,进行抽样调查,借助结构方程模型（SEM）对顾客抱怨处理公平性与口碑传播意愿之间的关系进行了实证分析。结果显示：顾客抱怨处理的程序公平性、互动关系公平性和补偿公平性对口碑传播意愿有非常显著的正向影响。当顾客的抱怨得到公平处理时,顾客感到很高兴并对消费经历感到满意,倾向于继续在该企业消费并向他人讲述经历,并推荐该企业或产品,企业应该尤其重视顾客抱怨处理的公平性。     

A Model of the Consumption Response to Fiscal Stimulus Payments

A wide body of empirical evidence finds that approximately 25 percent of fiscal stimulus payments (e.g., tax rebates) are spent on nondurable household consumption in the quarter that they are received. To interpret this fact, we develop a structural economic model where households can hold two assets: a low‐return liquid asset (e.g., cash, checking account) and a high‐return illiquid asset that carries a transaction cost (e.g., housing, retirement account). The optimal life‐cycle pattern of portfolio choice implies that many households in the model are “wealthy hand‐to‐mouth”: they hold little or no liquid wealth despite owning sizable quantities of illiquid assets. Therefore, they display large propensities to consume out of additional transitory income, and small propensities to consume out of news about future income. We document the existence of such households in data from the Survey of Consumer Finances. A version of the model parameterized to the 2001 tax rebate episode yields consumption responses to fiscal stimulus payments that are in line with the evidence, and an order of magnitude larger than in the standard “one‐asset” framework. The model's nonlinearities with respect to the rebate size and the prevailing aggregate economic conditions have implications for policy design.     

Knowing What Your Customer Wants: Improving Inventory Allocation Decisions in Online Movie Rental Systems

In Online Movie Rental Systems, customer desire to rent can often be observed before the actual consumption occurs. Desire represents uncensored (or true) demand information. Hence, the impact of inventory decisions (numbers of physical copies of different movies) can be accurately traced to the creation of desire (via Word‐of‐mouth), and then to rental. Word‐of‐Mouth (WOM) has been recognized as one of the most influential sources of information transmission, especially for experience goods. Poor inventory decisions may result in lost rentals in two ways: One is the loss of rentals because of low inventory (direct effect), and the other is the loss of the possible demand (rentals) that could have been created through WOM (indirect effect). We use data from an online DVD‐by‐mail firm to estimate the direct and indirect effects of inventory decisions, considering the circular relationship: Rental generates WOM, WOM creates Desire, and Desire turns into Rental. We find that the magnitude of indirect effects is significant, comparable to and sometimes even exceeding direct effects. The value of the empirical findings to facilitate better inventory allocation decisions is examined.

口碑效应下网络视频定价与广告投放最优决策

近年来，网络视频成为一种重要的新型消费内容，同时网络口碑对在线内容扩散的影响也日益深刻。本文考虑网络视频收费期内用户情绪效用产生的网络口碑对视频节目扩散过程的影响，运用数理分析方法，研究了网络视频运营商关于节目价格与广告投放量的最优决策问题，并分析了节目口碑属性、节目试看、节目体验质量和收费期等因素对最优决策结果的影响。研究发现，当付费用户与普通用户的视频体验质量差异足够大时，运营商将选择广告主导型策略(广告投放水平相对较高)，反之则选择收费主导型策略(收费水平相对较高)。当节目口碑越好、试看时间越短、付费模式体验质量越低或免费模式体验质量越高时，运营商越倾向于选择收费主导型策略，相应的节目价格、广告投放量和运营商期望利润也将视条件发生不同变化。基于前述最优决策结果，运营商可进一步针对节目口碑属性对收费期进行优化。
