Salesperson Resistance to Sharing Market Intelligence in Sub-Saharan Africa

This article presents a framework for exploring salesperson(s) resistance to sharing market intelligence in emerging markets in Sub-Saharan Africa. The authors propose that resistance to sharing market intelligence with relevant others, including the firm, coworkers, intermediaries, and sales managers, is a function of various individual, leadership, and organizational (firm) factors. This framework helps researchers understand how and why resistance develops among salespeople. Moreover, implications from these findings are presented to assist practitioners who wish to persuade and encourage African salespeople to share market intelligence for the benefit of their firms.

Does Greater Amount of Information Always Bolster Attitudinal Resistance?

Previous research suggests that attitudinal resistance to information that challenges a prior evaluation increases with the amount of information underlying the prior evaluation. We revisit this proposition in a context in which a set of important claims about a target brand are presented either alone—a lower amount of isolated information—or along with other favorable, but less important claims—a higher amount of embedded information. Results from two experiments show that when the challenge occurs immediately after the initial evaluation, a greater amount of embedded initial information does produce greater attitudinal resistance. However, when the challenge occurs after a delay, a lesser amount of isolated information produces greater attitudinal resistance. The findings qualify previous assumptions about the role of prior information in attitudinal resistance, and support a constructive view of judgment revision and attitudinal resistance.

Fungicide resistance and misinformation: A game theoretic approach

Fungicide resistance is a serious problem for agriculture today. This analysis provides additional insight into the strategic behavior of farmers when their fungicide use generates a negative intertemporal production externality in the form of fungicide resistance. We find that when farmers encounter this type of externality, they choose fungicide levels that exacerbate fungicide resistance. We examine a compensation mechanism in which a farmer reduces fungicide use in exchange for a transfer. This mechanism reduces fungicide use; however, misinformation about the severity of fungicide resistance generates distortions. We find that one-sided misinformation could lead a farmer to choose socially optimal fungicide levels, which makes the compensation mechanism less necessary. In addition, we show that when both farmers are misinformed, the mechanism could lead farmers to choose fungicide levels below the socially optimal level depending on their pessimistic beliefs about the severity of fungicide resistance.     

道德型品牌危机事件的溢出效应及应对策略研究

本文聚焦于道德型品牌危机事件对品牌的负面影响以及对品牌群内其他品牌的溢出效应。文章基于挫折-攻击理论和情绪应对理论,通过问卷调查法构建道德型品牌危机事件对消费者反应(抵制态度、负面口碑传播、购买意愿)的影响机制模型,并通过实验方法分析受到波及的企业如何应对负向溢出效应。研究结果表明,消费者对此类危机事件的关注和其民族中心主义会引起消费者进攻型负面情绪和规避型负面情绪的双重变化,但是只有进攻型情绪能够导致消费者对事件品牌和其他关联品牌的系列反应;受到波及的品牌短期内宜采用沉默而非辩解策略来化解负向溢出效应。本文结论为有关道德型品牌危机事件的研究提供了新的视角,并为外国和本土品牌在此类危机事件中如何应对提供了有针对性的管理建议。     

Classical Swine Fever Changes the Way Farmers Value Pigs in South Africa

Although there is growing demand for animal products in Africa, production is stagnating. Appropriate management of livestock diversity could help reinvigorate production, contribute to food security and improve farmers’ livelihoods, particularly in subsistence‐oriented systems. We assess differences in farmers’ preferences and economic values for pig traits across different production systems and across areas that have been affected and unaffected by classical swine fever (CSF). Not surprisingly, market‐oriented farmers derived higher values from the productive traits such as heavy slaughter weight and large litter size found in exotic pig genotypes. Subsistence‐oriented farmers, particularly in swine fever affected areas, placed high value on tolerance to disease. We found that CSF changed farmers’ preferences for adaptive traits, and less so for productive traits. Therefore, indigenous breeds become more valuable for subsistence farmers and crossbreeds for market‐oriented farmers if CSF is a risk. Our results can have implications for breeding and conservation strategies and for compensation strategies after culling, and will become increasingly relevant if, as predicted, heat waves and disease outbreaks become more frequent in pig production systems in South Africa with climate change.     

运动对抵抗素水平的影响及与胰岛素抵抗改善的相关性

在简要概述抵抗素生物学的基础上，对近年国内外有关运动与抵抗素的研究文献进行了回顾。注意到无论运动对抵抗素水平是否有影响，但可提高胰岛素敏感性，至于运动改善IR是否通过降低抵抗水平这一机制实现尚难以确定，且研究较少。     

钢筋混凝土叠合梁的斜截面承载力灰关联分析

为了经济合理地设计叠合梁，应用灰色系统理论，对均布荷载下钢筋混凝土叠合梁的斜截面积承载力及其关联因素进行关联度分析。结果表明，对叠合梁斜截面承载力影响最大的是预制梁混凝土强度等级，其次是叠合层混凝土强度等级、叠合特征参数αｈ，影响最小的是叠合特征参数αｍ。
