Economic lot size model for price-dependent demand under quantity and freight discounts

Abstract Previous studies have developed procedures which determine optimal lot size and selling price when demand depends on price and all-unit quantity discounts are offered. Further, recent studies have addressed the concepts of quantity and freight discounts for constant demand. In this paper, we incorporate quantity and freight discounts in inventory decision making when demand, rather than being constant, is considered to be dependent upon price. An algorithm is developed to determine the optimal lot size and selling price for a class of demand functions, including constant price-elasticity and linear demand. A numerical example is provided to illustrate the model and a computer program is developed to implement the model derived in the paper.

An advertising-inclusive production lot size model under continuous discount pricing

Abstract This article deals with the interaction of a deterministic production lot size inventory model with uniform replenishment rate and differential pricing conditions. We present a method for arriving at a production lot size formula, which takes into account the effect of varying marketing conditions on demand and the possibility of defective items in the production process. Additionally, based upon the previous studies, different model formulations are introduced to deal with the issue of defective items. The profile maximization problem for this model is derived for two quantity discount cases: hyperbolic-decreasing and linear-decreasing. A numerical example along with sensitivity analysis is provided to illustrate the results derived. Furthermore, an easy-to-use computer algorithm is developed to determine the optimal values of production lot-size and profit.

The impact of intrinsic motivation on satisfaction with extrinsic rewards in a nursing environment

Abstract Nurses in a hospital located in Southern US were surveyed to determine their perceptions of the reward structures existent in their hospital. Reward structures were divided into two categories: extrinsic and intrinsic. The cluster analysis procedure partitioned the sample into two clusters based on their level of satisfaction with the hospitals reward structure. The analysis of variance procedure comparing scale responses on comfort, challenge, financial reward, relation with coworkers, resource adequacy, and promotion suggest nurses with a high degree of intrinsic motivation are more satisfied with extrinsic rewards.

Sustainable Tourism: The Case of the Blue Ridge National Heritage Area

Tourist preferences for sustainable tourism products vary according to their demographic and socioeconomic characteristics. Results from a large sample in the Blue Ridge National Heritage Area found preference differences based on gender, age, education level, and income, as well as whether the tourist was a day-tripper or overnight visitor. The study found that the bulk of visitors originate in the southeastern United States, suggesting that promotions for the Blue Ridge area should be directed to those living in North Carolina and vicinity. Results from research such as this can assist sustainable tourism organizations to target promotions of various tourism activities to those who would be most interested.

An Empirical Analysis of Nurse Retention: What Keeps Rns in Nursing?

OBJECTIVE: This study investigates the effects of stress, economic factors, altruism, and value congruence on intentions to leave jobs and the nursing profession. BACKGROUND: Retaining nurses will be critical for healthcare organizations as the demand for nurses increases. Regulation and cost pressures are changing the nursing work environment. METHODS: We surveyed 861 RNs in the southeastern United States. Structural equation modeling was used to analyze the survey. RESULTS: Results confirm the importance of stress and salaries and underscore the impact of both value congruence and altruism. Evidence shows a correlation between altruistic desires and intentions to leave the profession. CONCLUSIONS: Efforts to retain nurses should include matching nurse and organizational values. Initiatives need to be undertaken to increase professional autonomy and provide opportunities for the expression of altruism. Further research is indicated to investigate the unexpected result that highly altruistic nurses are leaving the profession.

Effects of computer system components on the price of notebook computers

Abstract Several studies have been conducted to quantify the relationship between price and power of computer systems. Among the earliest and well known is that of Grosch, which dealt with mainframes. Recently, authors have made similar studies for desktop computers. However, some of the latest technology is in notebook computers. They are becoming more powerful, while size, weight, and prices continue to drop, and they are becoming one of the fastest growing segments of the computer market. This paper develops a model that identifies the computer characteristics that most significantly influence their price. The model can be utilized to perform price comparisons and in purchasing decisions for managers buying notebook computers.

Economic Impact of the Arts in a Small US County

This paper presents an assessment of the economic influence of the arts in a small county in the USA. The arts in this community consist of university, non-profit and private-sector employers and individual artists. A discussion of the methodology used to estimate the impact is provided. Over one thousand arts patrons and 62 artists and arts organizations responded to the survey. The direct and indirect economic impact of the arts in the community was estimated to be US

Addressing the Nursing Shortage: A Critical Health Care Issue

Development and innovative application of technology, as well as the integration of available technology, can provide an organisation with a unique opportunity to remain competitive in a global business environment. Although technology plays an important role in gaining competitive advantage for organisations worldwide, information technology professionals are becoming increasingly aware of the potentially harmful impact of misuse of information technologies. This paper provides a review of various technology-based threats and how they affect organisations. The paper further provides a taxonomy that depicts sources and targets of these threats and a process model to assist organisations in alleviating these threats. In addition to the five-stage threat alleviation model, a cause-and-effect diagram has been incorporated as a tool to help identify the sources of these threats as well as the potential outcomes of successful attacks. Organisations worldwide can use the taxonomy developed in this paper and the process to prevent these threats.

Enhancing retail services: an empirical investigation

This article explores factors that influence a nurses choice between working in a rural and an urban area. Understanding how nurses make the choice of which type of environment is critical to addressing this shortage, especially in these hardest hit rural areas. A comprehensive literature review suggested a number of factors worthy of investigation. These factors were assessed through six focus groups and a survey. Results suggest that native geographic preferences dominate, but that value congruence, economics, work facilities and stress all play a significant role in the decision when choosing between an urban and rural work environment.
