Driving organizational citizenship behaviors and salesperson in-role behavior performance: The role of management control and perceived organizational support

Interest in management control approaches and organizational factors associated with higher levels of salesperson performance is reflected in research streams concerned with behavior-based control strategies and organizational citizenship behaviors (OCBs). This study makes two distinct additions to the literature relating to control, organizational citizenship behaviors and salesperson performance. First, the study distinguishes between salesperson in-role behavior performance and outcome performance to model in-role behavior performance as a mediator between OCB and outcome performance. Second, the work supports sales manager control as an antecedent to OCB. A second model introduces perceived organizational support (POS) as an additional antecedent to salesperson OCB, and more important, as a consequence of sales manager control. This construct has not been included in prior salesperson OCB studies. Results show sales manage control has a stronger impact on OCB through POS, than directly, and POS has a strong impact on salesperson OCB. Nigel F.

羧甲基壳聚糖/海藻酸钠水凝胶pH值对溶胀行为的影响

以CaCl2为交联剂制备了一系列羧甲基壳聚糖/海藻酸钠水凝胶。研究了羧甲基壳聚糖与海藻酸钠溶液的配比、交联剂的用量以及pH值对水凝胶溶胀率的影响,并分析了不同pH值时水凝胶的红外谱图。结果表明,pH=1.0、3.0时,水凝胶收缩,而pH=5.0、7.4、9.0、13.0时,水凝胶溶胀随pH值增高,其溶胀率增大。当两者配比为1:3,pH 9.0时溶涨率最大。同时,红外谱图证明,水凝胶的pH敏感行为是氨基和羧基基团结构的变化所引起的。

新儒商思想对商业行为的影响

新儒商思想作为一种商业思想并在现阶段条件下提出，具有鲜明的时代特征和重要的现实意义。从我国古代、近代、现代的部分商业思想理论入手，结合儒学的有关发展史，对新儒商思想作一简单的论述。．长期以来儒学作为封建统治的工具，在政策上表现为重农抑商，然而这并不足以说明儒学在根本上是否认商业行为的，从某种意义上说，可作为一种哲学能够有效地指导、规范我们目前的商业经济行为。
