Business relationships: an examination of the effects of buyer‐salesperson relationships on customer retention and willingness to refer and recommend

Abstract: Examines the effect of the quality of a salesperson’s relationship with a customer on the likelihood of retaining that customer’s business. Assesses the effects of high/low‐quality buyer‐salesperson relationships on obtaining referrals and recommendations from a customer. Results indicate that buyers who rated the quality of their relationship with their salesperson as above average were more likely to remain. In addition, above average buyer‐salesperson relationships were more likely to generate recommendations and referrals from customers. Suggests that a salesperson’s efforts to build relationships are rewarded by greater customer retention and increased business through referrals and recommendations.

Improved fluorescence excitation-emission matrix regional integration to quantify spectra for fluorescent dissolved organic matter.

Abstract: The purpose of this short communication is to demonstrate the importance of numerical analysis and wavelength increment selection when characterizing fluorescent dissolved organic matter (FDOM) using fluorescence excitation-emission matrix (EEM) regional integration. A variety of water samples, representing a landscape gradient and different types of FDOM, were analyzed for their percentage distribution of five operationally defined FDOM fractions (aromatic protein I, aromatic protein II, fulvic acid-like, soluble microbial byproduct-like, and humic acid-like) using three numerical methods in integrating volume under the surface of the fluorescence EEMs: Riemann summation, composite trapezoidal rule, and composite Simpson's rule. The influence of wavelength increment was also examined for the precision of the percentage distribution of each fraction. Our results show that the FDOM fraction estimated by Riemann summation with a 10- or 5-nm excitation wavelength can cause >40% or >5% errors, respectively, when compared with the best estimated values obtained by averaging results from composite trapezoidal rule and composite Simpson's rule with 1-nm excitation wavelength at the same emission increment. Also, our experiments show that fluorescence matrix regional integration could underestimate the two aromatic protein fractions but could overestimate the soluble microbial byproduct-like and humic acid-like fractions if improper increment and integral methods are used. The error can be reduced if a smaller wavelength increment is used. The smallest increment in a spectrofluorometer and composite Simpson's rule should be used for scanning fluorescence EEMs and calculating the percentage distribution of each FDOM fraction. Alternatively, 5-nm wavelength increments with composite Simpson's rule could be cost effective, and the error of each FDOM fraction commonly falls within 5% compared with those estimated by 1-nm increments.

Does faculty development enhance teaching effectiveness

Abstract: Academic dentists and members of the practice community have been hearing, for more than a decade, that our educa- tional system is in trouble and that the profession has lost its vision and may be wavering in the achievement of its goals. A core of consistently recommended reforms has framed the discussion of future directions for dental education, but as yet, most schools report little movement toward implementation of these reforms in spite of persistent advocacy. Provision of faculty development related to teaching and assessment strategies is widely perceived to be the essential ingredient in efforts to introduce new cur- ricular approaches and modify the educational environment in academic dentistry. Analyses of the outcomes of efforts to revise health professions curricula have identified the availability and effectiveness of faculty development as a predictor of the success or failure of reform initiatives. This article will address faculty development for purposes of enhancing teaching effectiveness and preparing instructors for potential new roles associated with curriculum changes. Its overall purpose is to provide information and insights about faculty development that may be useful to dental schools in designing professional growth opportunities for their faculty. Seven questions are addressed: 1) What is faculty development? 2) How is faculty development accomplished? 3) Why is faculty development particularly important in dental education? 4) What happens when faculty development does not accom- pany educational reform? 5) Why are teaching attitudes and behaviors so difficult to change? 6) What outcomes can be expected from faculty development? and 7) What does the available evidence tell us about the design of faculty development programs? Evidence from systematic reviews pertaining to the teaching of evidence-based dentistry, strategies for continuing professional education, and the Best Evidence in Medical Education review of faculty development outcomes are presented to answer this question: does faculty development enhance teaching effectiveness? Characteristics consistently associated with effective faculty development are described.

Teaching computer organization/architecture with limited resources using simulators

Abstract: As the complexity and variety of computer system hardware increases, its suitability as a pedagogical tool in computer organization/architecture courses diminishes. As a consequence, many instructors are turning to simulators as teaching aids, often using valuable teaching/research time to construct them. Many of these simulators have been made freely available on the Internet, providing a useful and time-saving resource for other instructors. However, finding the right simulator for a particular course or topic can itself be a time-consuming process. The goal of this paper is to provide an easy-to-use survey of free and Internet-accessible computer system simulators as a resource for all instructors of computer organization and computer architecture courses.

Omnidirectional vision for an autonomous helicopter

Abstract: We present the design and implementation of an omnidirectional vision system used for sideways-looking sensing on an autonomous helicopter. To demonstrate the capabilities of the system, a visual servoing task was designed which required the helicopter to locate and move towards the centroid of a number of visual targets. Results are presented showing that the task was successfully completed by a Pioneer ground robot equipped with the same omnidirectional vision system, and preliminary test flight results show that the system can generate appropriate control commands for the helicopter.
