Science Education, EarlyView.ABSTRACT Scientists agree that learning to cope with failures is an important skill for science students to develop, and students who participate in science research often have positive outcomes after coping with science failures. However, the experience of failure in undergraduate science education more broadly seems to have an overall negative impact

Smuggling Sovereignty: Trade, Transgression, and State Authority
Economic Anthropology, EarlyView.ABSTRACT Global supply chains are saturated with transgressions—corruption, smuggling, document forgery, and other practices that blur the line between legality and illegality. States do not merely endure these practices; they actively shape the conditions for them, producing the very illegal systems they then claim to police.

Investing Aura: Making Value at an Emirati Art Center
Economic Anthropology, EarlyView.ABSTRACT The article examines the politics and processes of establishing value for artworks, highlighting the continued belief in Walter Benjamin's idea of aura and describing the value aura generates as “auratic value.” Focusing on an artist residency program in the United Arab Emirates (UAE) during the country's arts boom, I analyze contestations ...

Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Entrepreneurs in digital markets often introduce free versions of their paid products to boost their visibility. This freemium strategy involves a trade‐off between discovery and cannibalization. We study how feature‐based differentiation between the paid product and its free version shapes this trade‐off and its consequences ...

An efficiency enhanced cluster expanding block algorithm for copy-move forgery detection
, 2016 碩士本論文提出一個以多重分類為基準的複製移動竄改偵測技術，在多重分類的方法流程中，首先對影像所分割出來的區塊進行兩種不同的特徵提取，接著以兩種特徵值對區塊分別進行分類，並且將每個類別集合成大類以增加區塊相似度的範圍，透過多重分類篩選相似的區塊後，取在兩種分類中皆為同類別的區塊進行比對，可以有效的降低區塊間比對次數，使得在比對階段效率大幅提升，且同時過濾不相似區塊。比對階段時，利用由小到大的區塊擴張比對方式，可以在大量的比對動作中，有效減少其計算量，最後將偵測出區塊以記綠水平垂直距離的方式進行匹配 ...
