Consumer-based assessment of product creativity: A review and reappraisal

HUMAN FACTORS AND ERGONOMICS IN MANUFACTURING & SERVICE INDUSTRIES, Issue 2 2006
Diana Horn
In the current value-based economy, organizations compete to match customer needs and requirements by adding various types of value to products or programs. One example of this added value is product creativity, which is defined as the originality and appropriateness of a product that elicits a positive affect compatible with the consumer or judge. In this article, the authors review current research on creativity, product development, and consumer behavior and reappraise the current tools to measure product creativity. The overall conclusion of this review and reappraisal is that whereas product creativity shows relevance to consumer behavior, a more detailed model of product creativity and measurement tool needs to be developed and validated before fully understanding the impact of product creativity on consumer attitudes and purchase intentions. © 2006 Wiley Periodicals, Inc.

WATER EXCHANGES: TOOLS TO BEAT EL NIÑO CLIMATE VARIABILITY IN IRRIGATED AGRICULTURE,

JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 1 2004
Michael J. Scott
ABSTRACT: Using a case study of the Yakima River Valley in Washington State, this paper shows that relatively simple tools can be used to forecast the impact of the El Niño phenomenon on water supplies to irrigated agriculture, that this information could be used to estimate the significantly shifted probability distribution of water shortages in irrigated agriculture during El Niño episodes, and that these shifted probabilities can be used to estimate the value of exchanges of water between crops to relieve some of the adverse consequences of such shortages under western water law. Further, recently devised water-trading tools, while not completely free under western water law to respond to forecasted El Niño episodes (ocean circulation patterns), are currently being employed during declared drought to reduce the devastating effects of water shortages in junior water districts on high valued perennial crops. Additional institutional flexibility is needed to take full advantage of climate forecasting, but even current tools clearly could prove useful in controlling the effects of climate variability in irrigated agriculture. Analysis shows the significant benefit of temporarily transferring or renting water rights from low-value to high-value crops, based on El Niño forecasts. [source]


Revisiting DDGX/DDG-51 Concept Exploration

NAVAL ENGINEERS JOURNAL, Issue 3 2007

This study revisits concept exploration for DDG-51 using reconstructed 1978,1979 DDX and 1979,1980 DDGX requirements and options, and 2005 tools. The goal of this study is to assess and highlight the benefits of current tools and processes for concept exploration by comparison with a well-known design that did not use these tools. This case study was completed in a summer and fall ship design project at Virginia Tech. In 1979, the acquisition and design process did not begin with a Mission Need Statement, Analysis of Alternatives or Integrated Capabilities Document as is required today. It began with studies, Tentative Operational Requirements, and Draft Top Level Requirements. In this study, we revisit the 1978,1980 DDG-51 (DDX/DDGX) concept exploration based on the guidance, goals, and constraints of the DDX and DDGX studies, using a notional mission statement, concept of operations, and list of required capabilities. The design space is defined to include many of the same design alternatives that were considered in the DDX and DDGX studies. A multiple-objective genetic optimization (MOGO) based on military effectiveness, cost, and risk is used to search the design space and perform trade-offs. A simple ship synthesis model is used to balance the designs, assess feasibility, and calculate cost, risk, and effectiveness. Alternative designs are ranked by cost, risk, and effectiveness, and presented in a series of non-dominated frontiers. Concepts for further study and development are chosen from this frontier and a comparison with DDG-51 is made based on these results. [source]


Antimullerian hormone and inhibin B are hormone measures of ovarian function in late reproductive-aged breast cancer survivors

CANCER, Issue 3 2010
H. Irene Su MSCE
Abstract BACKGROUND: In late reproductive-aged breast cancer survivors, there is a need for real-time biomarkers of postchemotherapy ovarian function. The objective was to determine whether antimullerian hormone (AMH) and inhibin B are such biomarkers. The authors tested whether AMH and inhibin B were impacted by breast cancer treatment by comparing cancer survivors to age-matched control women and determined the association between these hormones and postchemotherapy menstrual pattern. METHODS: Breast cancer patients (n = 127) with American Joint Committee on Cancer stage I to III disease who were premenopausal at diagnosis were enrolled postchemotherapy and observed. The primary endpoint was chemotherapy-related amenorrhea (CRA) (,12 months of amenorrhea after chemotherapy). Matched pair analyses compared AMH, inhibin B, and follicle-stimulating hormone (FSH) levels between cancer and age-matched control subjects. Associations between hormones, CRA status, and change in CRA status over time were assessed. RESULTS: The median age of the patients at chemotherapy was 43.2 years (range, 26.7-57.8 years). At enrollment, median follow-up since chemotherapy was 2.1 years, and 55% of subjects had CRA. Compared with age-matched controls, cancer subjects had significantly lower AMH (P = .004) and inhibin B (P < .001) and higher FSH (P < .001). AMH (P = .002) and inhibin B (P = .001) were found to be significantly associated with risk of CRA, even after controlling for FSH. AMH was significantly lower (P = .03) and FSH was significantly higher (P = .04) in menstruating subjects who developed subsequent CRA. CONCLUSIONS: AMH and inhibin B are 2 additional measures of postchemotherapy ovarian function in late reproductive-aged breast cancer survivors. With further research and validation, these hormones may supplement limited current tools for assessing and predicting postchemotherapy ovarian function. Cancer 2010. © 2009 American Cancer Society.
