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。     

政治委托代理中的地方政府经济行为有效性分析

用经济学激励理论分析政治代理人的经济行为,可以发现官员外在激励有效性不高的原因.在委托代理关系中,激励要有效必须具备一定条件;而在政治委托代理关系中,由于满足激励有效性的条件难以具备,使得委托人对官员的业绩很难考核准确,很难实行货币奖励.官员的业绩不能准确考核,官员就会出现道德风险,官员得不到货币奖励,就会出现经济行为政治目的,两者都会增加代理成本和社会福利的损失,导致激励考核有效性缺乏和激励奖励有效性缺乏.这在我国经济中的具体表现就是地方政府经济行为非经济性严重.从中也可看出一个合格的官员自我内在激励的重要性.

金融犯罪种类划分及其特征揭示——兼论金融犯罪的此罪与彼罪之界分

金融犯罪作为一种新型经济犯罪,目前立法、司法部门及刑法学界对有关此类犯罪问题的研究尚不够全面、深入,其中对金融犯罪进行科学、合理分类并揭示其特征是亟需研究的基本问题之一。通过综合研析刑法理论界颇具代表性的客体、行为、混合等诸种分类法之优劣,紧密结合我国现行刑法所作的立法分类,提出以混合分类法为基本思路,依据金融犯罪所侵犯客体的相同性,兼顾犯罪方法的特殊性,作进一步的分类细化,以期形成符合我国实际的金融犯罪分类设想;同时,充分揭示不同类型金融犯罪构成特征,全面把握金融犯罪此罪彼罪界限所在,从而为金融刑事立法不断完善以及司法部门正确定罪量刑提供有利的依据。
