Perceived product creativity and mental contrasting: Desired future on consumers’ product replacement decisions

Consumers often imagine what it would be like to own a new product. Does engaging in such thoughts on desired future impact consumers’ purchase intentions, and if so, what is the underlying process? This study sets out to investigate the posed questions by assessing self‐regulatory strategies consumers employ upon pondering on a desired future. Based on Oettingen’s fantasy realization model, the authors take a comparative approach of two modes on desired future—mental contrasting and indulging—en route to purchase intentions. In mental contrasting, an individual juxtaposes a desired future with his/her present reality, whereas, indulging is simply envisioning a desired future. Contingent upon the perceived likelihood of fantasy realization, consumers in the mental‐contrasting condition adjust their level—that is, high (low) for high (low) feasibility case—in goal commitment as well as in energization to achieve the desired future. In contrast, consumers in the indulging condition engage in moderate level of goal commitment—irrespective of the likelihood of fantasy realization. In a series of experiments, this study scrutinizes the fantasy realization model in context of attribute alignability/nonalignability, uncertainty in attribute meaningfulness and novelty, technological and psychological obsolescence en route to affecting the consumers’ product purchase/upgrade intentions. Conceptually, this study is the first to adapt the fantasy realization model to the marketing context, and the authors provide managerial implications of their key findings.     

食品安全规制能提高生产者福利吗？——基于不同规制强度的检验

食品安全规制涉及政府、生产者和消费者三方利益主体的博弈。已有文献主要关注政府规制对减少生产者违规概率、提升食品安全水平和消费者福利所产生的作用。本文从生产者福利视角考察企业参与食品安全规制是否存在“收益率溢价”效应，以此对中国食品安全规制的间接效果进行实证检验。首先采用倾向得分匹配模型考察食品安全规制对企业资产收益率的平均影响效应，然后采用广义倾向得分匹配模型和门槛模型进一步考察不同规制强度与企业资产收益率的非线性关系。研究表明，当前食品安全规制对参与规制企业产生了“收益率溢价”的间接效果,但随着规制强度的扩展，企业资产收益率呈现先上升后下降的“倒U型”变化，具有显著的双重门槛特征，当企业持有4项质量认证证书时为“最优规制强度”。最后结合当前中国实际，解释了上述结论产生的原因及政策含义。     

预应力梁高强、超早强混凝土的配制技术

本文介绍了水泥掺减水剂、减水剂和水泥双掺粉煤灰与减水剂和水泥双掺磨细矿碴的三个配合比设计方案,比较了52.5MPa水泥和42.5MPa的配制效果,同时也比较了各种掺合料在不同掺量时的配制强度,配制出了3天达设计等级强度90%,可同时满足预制梁和连续梁施工技术要求的高强、超早强预应力混凝土配合比设计方案。     

再生细骨料取代率对再生混凝土抗压强度的影响

建筑废弃物经过除杂、二次破碎可以得到粒径范围为0-4.75mm的再生细骨料。本文研究了不同水灰比条件下,再生细骨料取代率对再生混凝土抗压强度的影响。结果表明:当再生细骨料取代率由10%增加到40%时,再生混凝土7天抗压强度逐渐降低。再生混凝土28天抗压强度随着再生细骨料取代率的增加逐渐降低,取代率在50%以下时,28天抗压强度降低幅度较小且满足设计要求。再生细骨料用于实际工程中,其社会效益和经济效益十分可观。     

影子连带强度及其影响因素研究

以过去型影子连带为例,基于扎根理论方法探索影子连带强度及其影响因素,编制影子连带强度及其影响因素的量表,并选择销售人员为样本,验证了影响因素对影子连带强度的作用。研究结果显示:在个体层面,主体对客体的认同以及主客体过去的关系强度对影子连带强度有正向影响;客体的网络位置及其拥有的资源对影子连带强度有正向影响;在环境层面,外界环境对客体的强化对影子连带强度有积极的影响。     

基于主成分分析的企业专利实力评价研究

企业的专利实力反映了企业的技术创新能力、市场竞争力和企业发展的活力。对企业专利综合实力进行评价,能使企业把握科技发展的动态,了解技术创新中的优势和不足,并科学地调整企业的创新策略。本文以发明专利作为研究对象,选取了有代表性的专利评价指标,从申请类、授权类、专利维持、专利范围、专利引证五个维度构建了企业专利实力评价指标体系,并运用主成分分析方法,对2001至2005年美国专利申请量排名前20的企业专利综合实力进行评价。     

股票资金流强度的实证研究及评测

在资金博弈的股票市场中,资金流向确认与计算是金融工程的一大理论难题,国内有学者在现有资金流计算方法基础上,提出了股票资金流强度模型和构建了股票资金流指数指标体系。根据统计分析方法利用SPSS软件对股票资金流强度和股价波动环比增长率进行相关性分析,进而实证股票资金流强度指标的有效性。实证结果表明股票资金流强度与股价波动环比增长率呈线性趋势,从而利用股票资金流强度指标可以很好地预测股价的变化。

Effect of CEO power and board strength on bank performance in China

Given that a powerful CEO is more likely to overcome problems and control performance in a firm, this study first focuses on exploring whether CEO power positively affects certain measures of bank performance and which sources of CEO power have these positive impacts. Next, this study further analyzes whether the positive impact of CEO power on performance is negatively mediated by board strength. Our sample includes data on the three main types of Chinese banks for 2006 to –2016.Our results show that CEO structural power significantly improves a bank’s overall profitability, risk-taking ability and lending quality, CEO ownership power significantly raises a bank’s lending quality, and CEO expert power significantly increases a bank’s overall and shareholder profitability. As considering the endogeneity, CEO prestige power significantly improves a bank’s overall profitability. Next, we use the proportion of independent directors as our measure of board strength and find that a stronger board reduces the beneficial effects of CEO structural power on a bank’s lending quality, of CEO ownership power on shareholder profitability, and of CEO expert power on lending quality. There are similar harmful mediating effects when we use the proportion of foreign investors and board size as measures of board strength. Our results can help Chinese bank authorities develop policies to appropriately raise bank CEOs’ power and reduce board supervision of CEO power.     

凿井水下底卸式自动卸料吊桶

吊桶是立井井筒开凿时期提升矸石和运送材料及升降人员的主要容器,吊桶的卸矸目前多采用挂钩式或座钩式卸料方式;但是随着矿井的开凿深度不断延伸,在过透水层时,由于探放水不及时或涌出水比较大,超出了井筒的排水量,或者是由于冷冻井在解冻后,井筒的井筒质量不过关,各别井壁也会发生透水事故;这就会出现淹井事故,有时淹井深度达二三百米。对于处理这种淹井事故,往往只有一个办法,那就是用沙或混凝土对井筒回填;这就需要吊桶在下到几百米下的水底自动把料卸掉,但现在矿井常用的挂钩式吊桶和座钩式吊桶已经不能满足这个需要了。
