Proactive behavior and industrial salesforce performance

Proactive behavior has been indirectly linked to effective selling, an assertion underpinned by a logic, which states that in a world of high competition and choice, the passive, reactive seller is unlikely to do as well as his or her more proactive counterpart. Yet, little direct empirical evidence exists to substantiate this link. In this paper, we address this knowledge gap by describing a study that assesses the effect of proactive behavior on the performance of an industrial sales force. The paper explores the issue of salesperson performance and the construct of proactive behavior (or proactiveness). Using the Proactive Personality (PP) Scale to measure proactiveness and the line manager's subjective evaluation to indicate salesperson performance, it was found that a small but significant relationship exists. The results are discussed, with areas for future research delineated and implications for practitioners explored.     

Marketing activities and performance: A comparison of the Internet-based and traditional small firms in Taiwan

Emerging technologies, notably, have redefined business by erasing the traditional boundaries of time and geography and by creating new virtual communities of customers, distributors and suppliers, with new demands for products and services. Are there any differences between the marketing practices of the Internet-based and traditional small firms? This paper analyses published, undisguised stories of 112 traditional and 26 Internet-based small firms in Taiwan. The research results suggest that the owner-managers of both traditional and Internet-based small firms concentrate on sales, product planning and customer relationships. However, the owner-managers of traditional small firms in Taiwan place emphasis on quality control, whereas their Internet-based counterparts concentrate more on product schedules, sales forecasts, sales control and marketing research. These results indicate that cyber entrepreneurs have higher levels of marketing education and backgrounds, conduct marketing planning periodically and frequently and perform professional marketing activities. The research findings tend to suggest that though traditional marketing tenets are still suitable in the cyber environment of Taiwan, the Internet-based small firms have to utilise innovative marketing techniques to suit and compete in the ever-changing Internet business environment.     

Going the extra mile: Antecedents of salespeople's discretionary effort

Many sales organizations are scrambling for success in today's intensely competitive environment. An increasing number of firms are finding that tried and true traditional selling strategies are less effective, or not effective at all. Moreover, companies are discovering that what has been an acceptable level of performance no longer is adequate for maintaining or gaining competitive advantage. Consequently, managers need to focus on alternative means through which the organization can be successful. One alternative is for sales forces to engage in discretionary effort-work activities that entail going beyond the call of duty. This paper develops propositions regarding antecedents of salesperson discretionary effort, which provide managerial direction should the propositions be confirmed.     

Managing radical innovation: an overview of emergent strategy issues

Despite differences in definitions, researchers understand that radical innovation within an organization is very different from incremental innovation , and and that it is critical to the long-term success of firms. Unfortunately, research has also shown that it is often difficult to get support for radical projects in large firms [14], where internal cultures and pressures often push efforts toward more low risk, immediate reward, incremental projects. Interestingly, we know considerably less about the effective management of the product development process in the radical than in an incremental context. The purpose of this study is to explore the process of radical new product development from a strategic perspective, and to outline key observations and challenges that managers face as they move these projects to market. The findings presented here represent the results of a longitudinal (since 1995), multidisciplinary study of radical innovation projects. A multiple case study design was used to explore the similarities and differences in management practices applied to twelve radical innovation projects in ten large, established North American firms. The findings are grouped into three high-level strategic themes. The first theme, market scope, discusses the challenges associated with the pursuit of familiar versus unfamiliar markets for radical innovation. The second theme of competency management identifies and discusses strategic challenges that emerge as firms stretch themselves into new and unfamiliar territory. The final theme relates to the people issues that emerge as both individuals and the project teams themselves try to move radical projects forward in organizations that are not necessarily designed to support such uncertainty.A breadth of subtopics emerge within and across this framework relating to such ideas as risk management, product cannibalization, team composition, and the search for a divisional home. Taken together, our observations reinforce the emerging literature that shows that project teams engaging in radical innovation encounter a much different set of challenges than those typically faced by NPD teams engaged in incremental innovation.     

Science and politics: The 1981 and 1984 LIHEAP distribution formulas

The Low-Income Home Energy Assistance Program (LIHEAP) is a federal block grant program to help low-income households pay their heating and cooling bills. If the regular fiscal year LIHEAP appropriation is less than or equal to $1.975 billion, then a 1981 formula is applied to distribute funding across states, while if appropriations rise above the $1.975 billion threshold, a 1984 formula is applied in conjunction with two hold-harmless provisions. In 18 of the past 20 years, the 1981 formula has served as the default mechanism to distribute LIHEAP funding. The purpose of this paper is to call attention to the inadequacy of the 1981 formula and to explain why the objectives of LIHEAP are not met when this formula is used. We explain why the distribution of LIHEAP funds is not proportionate to the need for assistance and offer some suggestions for improvement. The 1981 formula is shown to be the outcome of a convoluted political process heavily biased in favor of cold-climate states, with cold-climate states receiving on-the-order of at least $150 million a year in allotment dollars beyond their “fair share” of heating requirements. The 1981 and 1984 distribution formulas are derived and a critical examination of each formula is presented. The 1984 formula is shown to be an ideal mechanism to distribute LIHEAP funds, based on a scientific and rational understanding of low-income energy needs, but legislative constraints prevent its application.     

Music,music videos,and wear out

Repeated exposure to a music video was found to forestall wear out relative to repetitive exposure to the music only. Susceptibility to wear out in the case of the music video was further reduced by eliminating the closure associated with the story told by the video. The level of positive cognitive responses was posited as a mediator to help explain the observed results. © 1993 John Wiley & Sons, Inc.     

HOW FIRMS MANAGE RISK: THE OPTIMAL MIX OF LINEAR AND NON-LINEAR DERIVATIVES

This paper provides guidance on how corporations should choose the optimal mix of "linear" and "non-linear" derivatives. Linear derivatives are products such as futures, forwards, and swaps, whose payoffs vary in linear fashion with changes in the un-derlying asset price or reference rate. Non-linear derivatives are contracts with option-like payoffs, including caps, floors, and swaptions.
A company's optimal hedging position should generally consist of linear contracts because of their effective-ness in smoothing corporate cash flows. But as the firm's business (quantity) risk increases, its use of linear contracts will decline due to costs associated with overhedging. At the same time, there will be a shift towards the use of non-linear contracts. The degree of substitution of non-linear for linear in-struments will depend on the relation-ship between the quantities to be hedged and market prices. A negative relationship will tend to exacerbate the substitution effect while a positive re-lationship will dampen the effect. An empirical examination of corporate derivative holdings provides support for all of the major hypotheses.     

How can nurses help patients work more effectively with nurses to improve the safety of patient care?

The literature seems quite clear that patients still regard the nurse as the principal link between the technical and interpersonal aspects of their care. The often-discussed medical error crisis tends to create in the patient mistrust of all care providers. The health care industry is driving towards a system that requires patients to be self-reliant in managing their care, without allowing for factual limitations in patient capability, ability, and interest in such an enterprise. Unfortunately for the overworked, understaffed nurse, patients still look to them to provide quality compassionate care without the patient having to police them. Health care providers have been mandated to provide assessment and intervention for pain management. It was mandated because we as health care professionals failed to perform this vital function in a consistent, quality manner. It did add to the workload of the nurse. However, if done properly, it is a valuable communication tool for the nurse and the patient to comfortably discuss pain and its management--the interpersonal part of care.     

A fragmented patient safety concept: the structure and culture of safety management in health care

The uniform and visible commitment to safety management is a cultural and structural change that health care organizations have not typically attempted. Committee structures are just one example of how culture drives structure in managing health care safety. The question is: "Are we interested in making nonpatient safety programs as well understood and as culturally significant as patient safety programs?" Models exist to institutionalize safety management in health care. We need only look to the JCAHO or OSHA and other high-hazard industry models for examples of safety management. Change requires a focus on safety, not occupational safety or patient safety, but just safety. In health care, safety would be a key characteristic of organizational culture. The organizational expectation is then that all employees will work safely and practice safety. Employees will apply safe practices when handling chemicals, in lifting, and when giving medications. Only when safety imbues the work and decisions of each employee in this way will the highest level of safety be attained.
