“…AHP could be implemented by four steps: structuring the decision problem, measurement and data collection, determination of normalized weights, and synthesis toward-finding solution to the problem [47]. Its formulas and detailed descriptions could be found in several studies [48,49].…”

Abstract:The development of an ecosystem health index to assess health status in freshwater lakes is urgently needed in China, especially in polluted lakes. This study developed a specific Ecosystem Health Index (LP-EHI) for Lake Poyang in China. LP-EHI quantified lake health from the perspectives of physical, chemical, biological integrity and social service. Physical integrity indices included hydrological conditions (water level and runoff), basic morphometric characteristics (lake area and shoreline), and tributary connectivity. Chemical integrity indices used water quality, nutrition, and toxicity to quantify chemical impairment. Biological integrity indicators covered six major components of the aquatic food chain, namely, phytoplankton, zooplankton, benthic macroinvertebrates, wetland plants, fish, and wintering birds. Social service indices included drinking water, pathogenic potential, flood storage capacity, sand mining, and dish-shaped sub-lake areas under management to measure whether the lake fulfilled the needs of human society. Reference and impaired conditions for each metric were defined by "historical" conditions, "least disturbed" conditions, national standards and expert opinions. The value of LP-EHI ranging from 0 to 1 was divided into five health conditions: excellent (≥0.8), good (0.6-0.8), fair (0.4-0.6), poor (0.2-0.4) and bad (<0.2). The metrics' reliability was further validated using a box-and-whisker plot test. The developed index (LP-EHI) is so far the most comprehensive index to evaluate ecosystem health for Lake Poyang, and is well reflected in the unique characteristics of Lake Poyang. It can enhance our understanding of lake health conditions and thus guide lake management to achieve better health conditions.

“…Çünkü AHS uygulamalarında kararlara birden fazla kişinin katılması durumunda, bu kişilerin kararlarından tek bir hüküm çıkarılması gerekmektedir (Özden, 2008: 304). Bunun için en uygun yöntemin, katılımcıların vermiş oldukları cevapların geometrik ortalamalarının alınmasıdır (Tam ve Tummala, 2001). Geometrik ortalamanın en uygun yöntem olmasının sebebi ise, karşılaştırma matrisinde simetrik elemanların birbirinin tersi olması gerektiği kuralını sağlamasıdır (Ömürbek ve Tunca, 2013: 58 Bu faktörler Kozaklı'nın termal turizmde rakiplerine nazaran rekabet avantajı kazanmasında belirleyici faktörler olarak tespit edilmiştir.…”

“…With too many criteria, supplier selection becomes difficult and time-consuming. It may also lead to evaluator's assessment bias [54]. In this study, criteria cut-off is processed based on the level of importance of each criterion using the natural cut-off point method [64].…”

Abstract. : As class time is a limited resource, knowing when cm additional inclass example would most benefit student learning would be an advantageous tool for optimizing the use of class time. The authors integrated daily learning objectives into at rapid feedback system to collect students' perceptions of concept mastery after every lecture. This early feedback system allows the instructor to include additional in-class examples, when most of the class was confused, or to reach out individually, when only a few students were faltering. This paper describes this innovative classroom technique as it has been applied in two engineering technology courses: Construction. Estimating and Structural Analysis. Key findings are that students overwhelmingly believe that the daily objectives help them learn the material, that additional in-class examples can significantly improve understanding for cases of widespread confusion, and, as such, that this system enables the instructor to discern when to spend valuable class time on additional in-class examples.
