Abstract The domestic market is the primary market of the Indonesian locally produced mango. There is a positive transition in the economy in this market, highlighting the increase of healthy lifestyles and changes in fresh agri-food product preferences, including fresh mango. Understanding how consumers in this community have a variation in preferences is essential to formulate the strategy to improve the performance of the Indonesian mango value chain. This study aims to identify quality attributes of fresh mango considered important by Indonesian domestic consumers. An online consumer survey involving 435 consumers was conducted in February 2021 in Jakarta, the biggest city in Indonesia. Based on the hierarchical cluster analysis, consumers are divided into four clusters based on their perception of the importance of mango quality attributes. The results highlight the differences between four clusters of respondents in giving importance to intrinsic and extrinsic mango quality attributes, where three out of four clusters concern with quality attributes importance. The differences in respondent characteristics in each cluster can represent how different consumers give importance to a mango quality attribute. It can be valuable information to improve mango value chain performance by understanding that most consumers are concerned about mango quality attributes’ importance.

Unpredictable and uncontrollable situations have happened throughout history. Inevitably, such situations have an impact on various spheres of life. The coronavirus disease 2019 has affected many of them, including sports. The ban on social gatherings has caused the cancellation of many sports competitions. This paper proposes a methodology based on hierarchical cluster analysis (HCA) that can be applied when a need occurs to end an interrupted tournament and the conditions for playing the remaining matches are far from ideal. The proposed methodology is based on how to conclude the season for Serie A, a top-division football league in Italy. The analysis showed that it is reasonable to play 14 instead of the 124 remaining matches of the 2019–2020 season to conclude the championship. The proposed methodology was tested on the past 10 seasons of the Serie A, and its effectiveness was confirmed. This novel approach can be used in any other sport where round-robin tournaments exist.

In this study a method proposed by Byun & Wilhite, which estimates drought severity and duration using daily precipitation values, is applied to data from stations at different locations in Greece. Subsequently, a series of indices is calculated to facilitate the detection of drought events at these sites. The results provide insight into the trend of drought severity in the region. In addition, the seasonal distribution of days with moderate and severe drought is examined. Finally, the Hierarchical Cluster Analysis method is used to identify sites with similar drought features.

AbstractIn this study, we identify patterns among students beliefs and ideas in cosmology, in order to frame meaningful and more effective teaching activities in this amazing content area. We involve a convenience sample of 432 high school students. We analyze students’ responses to an open-ended questionnaire with a non-hierarchical cluster analysis using the k-means algorithm.
