Needed B2B marketing capabilities: Insights from the USA and emerging Latin America

Firms from all parts of the world are expanding operations globally in a turbulent economic context, requiring the understanding of nontraditional markets. Much attention has been focused on China and India, but researchers have neglected Latin America, a region economically as important as Germany, India, Japan, and South Korea. Latin America, as is true of many developed and emerging markets, has a strong presence of industrial ? or business to business (B2B) ? transactions. The configuration and convergence-divergence of marketing capabilities are relevant for the understanding of the globalization phenomenon. This study aims to examine B2B marketing capabilities of firms in Chile, Mexico and Peru (as Latin American countries), seeking conceptual issues in order to comprehend their business perspectives and contribute to the almost nonexistent body of research in this region. How do the results from Latin America compare with the USA? While the study shows directional convergence between Chile and Peru, there also is interesting divergence between all Latin American countries and the USA. The findings offer a portfolio of marketing topics that we believe are worthy of practitioner and academic consideration. We propose a model of convergence-divergence of B2B marketing capabilities across nations and state propositions for hypothesis testing.     

Selection from Logistic populations

Assume k ( k ≥ 2) independent populations π₁, π₂μ_k are given. The associated independent random variables X_i,( i = 1,2,… k ) are Logistically distributed with unknown means μ₁, μ₂, μ_k and equal variances. The goal is to select that population which has the largest mean. The procedure is to select that population which yielded the maximal sample value. Let μ₍₁₎≤μ₍₂₎≤…≤μ_(k) denote the ordered means. The probability of correct selection has been determined for the Least Favourable Configuration μ₍₁₎=μ₍₂₎==μ_{(k – 1)}=μ_(k)–δ where δ > 0. An exact formula for the probability of correct selection is given.     

Heroview组态软件与GE PLC的通讯研究

工业控制中PLC与上位机的通讯实现方式种类繁多,不同PLC可以选择与不同上位组态软件进行通讯连接,通讯是否正常,主要取决于该组态软件是否有与PLC连接的I/O驱动程序以及驱动程序配置是否合理。Heroview组态软件与GE PLC都广泛应用于工控领域,建立它们之间的通讯有较大的现实意义,本文主要介绍了Heroview与GE PLC的通讯方式及其配置过程。     

The influence of an optimal control system on salesperson performance and championing

In this study, the effect of a deviation from an optimally blended control system on salesperson performance and championing is investigated. Blended control systems represent combinations of many different forms of control, affording sales managers the opportunity to better match a control system with the overall context in which their firm operates, addressing such things as current salesperson, firm, and environmental variables. The extent to which the blended system represents an appropriate match with the overall context, however, is of primary concern. As demonstrated here, deviations from optimal control negatively affect both individual salesperson performance, as well as salesperson championing. In combination, these findings emphasize the importance of understanding a broader picture of salesperson control than is allowed through simple direct effect analysis.     

基于fsQCA方法的创业孵化基地高质量发展评价研究

新时代下我国经济发展由高速增长转为高质量发展，创业孵化基地作为大众创业的承载平台，其高质量发展可以发挥示范效应和带动作用。以江西省28家创业孵化基地为调查研究对象，运用线性加权平均法、TOPSIS法和功效系数法三者集成得到的综合评价得分作为fsQCA中发展质量的测量值，在组态视角下对创业孵化基地高质量发展进行评价。结果表明，服务内容主导型、品牌塑造主导型和服务能力—社会影响力主导型3条路径可以引致创业孵化基地高质量发展；创业孵化基地高质量发展具有多重并发性，不同影响因素的组合构型有互不冲突的完全等效性，遵循殊途同归原则；创业孵化基地高质量发展评价与非高质量发展评价之间具有因果非对称性。     

企业原始创新驱动路径研究——基于TOE框架的组态分析

企业原始创新是解决科技“卡脖子”问题的重要手段，也是推动科技自立自强的重要举措。在TOE框架下，结合现阶段企业原始创新特点，提出分析企业原始创新绩效差异的整合性框架，并采用fsQCA方法进行深入分析。结果表明，实现企业高原始创新的组态路径有5条，分别是技术与市场主导下的技术管理与原始创新氛围驱动型、技术与市场主导下依托政策的高管支持与技术管理驱动型、技术与市场主导下的原始创新氛围与政策驱动型、技术主导下依托政策的技术管理与组织因素驱动型以及市场主导下依托技术管理的原始创新氛围与高管支持驱动型；从企业高原始创新组态路径中发现，技术、组织和环境3个层面要素之间具有互补替代关系，可为处于不同场景下的企业获取高原始创新绩效提供有益参考；导致企业非高原始创新的组态路径有两条，且都包括非高技术能力、非高程度高管支持、非高市场导向和非高政策导向，表明技术、组织和环境层面要素的缺失导致企业原始创新绩效不高。结论可为驱动企业原始创新提供重要理论依据。     

高科技企业离职员工创业机会创新性的影响机制研究——基于模糊集定性比较分析

高科技企业离职员工创业成为数字经济时代的普遍现象，现有研究大多关注离职员工为何离职创业，而忽略了对离职创业结果的探究。聚焦于离职员工创业机会创新性，以华为26个离职创业样本为研究对象，应用组态思维整合文化情境和个体特征两个层面因素，探究创业机会创新性背后多重条件间的复杂互动本质。研究发现：文化情境与个体特征因素联动匹配影响创业机会创新性的实现；影响高-低创业机会创新性的路径呈现差异性，高创业机会创新性的影响模式为创业自信驱动型、知识能力主导型与个体-组织协同型，低创业机会创新性的影响模式为过度自信触发型与创业特质缺乏型。
