Toward Enhancing the Quality and Quantity of Marketing Majors

This article reports the findings of a survey of undergraduate students designed to examine the key factors involved in selecting a marketing major. A discussion follows, dealing with the initiatives undertaken by marketing departments at various universities in an attempt to enhance the quality and quantity of marketing majors.Statistics Working Papers Serie

Customer Retention and Unplanned Purchases on the Web

The explosion of business to consumer electronic commerce creates new challenges for companies to design electronic systems and interactions that retain customers and increase sales. This exploratory study examines the impacts of select system design and other variables that can influence customer intention to return and the number of unplanned purchases made in an online store. We find that both the level of perceived control and the shopping enjoyment experienced by new web customers can increase their intention to return. However, repeat customers do not seem to be influenced by either perceived control or shopping enjoyment in terms of their intention to return. We also find that an engaging web store design that utilizes value-added search mechanisms and presents a positively challenging experience can increase the customers' perceived control and enjoyment. Our results also indicate that product involvement is less important to new customers as opposed to repeat customers but the more often customers return to a web store the more their shopping enjoyment is determined by their product involvement. Finally, our study shows that neither perceived control nor shopping enjoyment have any significant impact on the number of unplanned purchases made by customers. Our results deepen our understanding of the consumer online shopping experience and suggests the need for the design of systems which increase the user's perceived control to encourage repeat use of online storesInformation Systems Working Papers Serie

Pericyte NF-κB Activation Enhances Endothelial Cell Proliferation and Proangiogenic Cytokine Secretion in Vitro

Pericytes are skeletal muscle resident, multipotent stem cells that are localized to the microvasculature. In vivo, studies have shown that they respond to damage through activation of nuclear-factor kappa-B (NF-κB), but the downstream effects of NF-κB activation on endothelial cell proliferation and cell–cell signaling during repair remain unknown. The purpose of this study was to examine pericyte NF-κB activation in a model of skeletal muscle damage; and use genetic manipulation to study the effects of changes in pericyte NF-κB activation on endothelial cell proliferation and cytokine secretion. We utilized scratch injury to C2C12 cells in coculture with human primary pericytes to assess NF-κB activation and monocyte chemoattractant protein-1 (MCP-1) secretion from pericytes and C2C12 cells. We also cocultured endothelial cells with pericytes that expressed genetically altered NF-κB activation levels, and then quantified endothelial cell proliferation and screened the conditioned media for secreted cytokines. Pericytes trended toward greater NF-κB activation in injured compared to control cocultures (P = 0.085) and in comparison to C2C12 cells (P = 0.079). Second, increased NF-κB activation in pericytes enhanced the proliferation of cocultured endothelial cells (1.3-fold,P = 0.002). Finally, we identified inflammatory signaling molecules, including MCP-1 and interleukin 8 (IL-8) that may mediate the crosstalk between pericytes and endothelial cells. The results of this study show that pericyte NF-κB activation may be an important mechanism in skeletal muscle repair with implications for the development of therapies for musculoskeletal and vascular diseases, including peripheral artery disease

Consumer Protection Laws: Violator Detection and Enforcement Strategy

A methodology is proposed for both the assessment and enforcement of consumer protection laws and regulations. An assessment model is presented to determine the effect of a law (e.g., violation rate, characteristics and/or profile of violators) and then a cost efficient law enforcement strategy is described that is aimed at the violator population identified by the assessment model. This methodology consists of a short enforcement campaign, directed mainly against the violators, and is then followed by an inexpensive maintenance program. Data for the assessment model are collected based upon an interrupted stratified time series design where the stratification scheme is selected by satisfying a minimum variance criterion. The stratification rule may vary so that a dynamic representation of the changing characteristics of the violator population is obtained.log linear models, control theory application, law enforcement strategies, consumer protection
