Indirect reciprocity occurs when the cooperative behavior between two individuals is contingent on their previous behavior toward others. Previous theoretical analysis indicates that indirect reciprocity can evolve if individuals use an image-scoring strategy. In this paper, we show that, when errors are added, indirect reciprocity cannot be based on an image-scoring strategy. However, if indiv...

GQM+Strategies is an approach that aligns the business goals at each level of an organization to strategies to achieve overall business goals and assesses the achievement of such goals. Strategies are extracted from business goals based on rationales (contexts and assumptions). Using the proposed approach, which refines the GQM+Strategies model by extracting rationales based on the analysis of ...

Wetten, dass?: Indirect requests in a German game show I aim to show that German speakers, though seemingly more direct than English speakers, do in fact employ multiple indirect request strategies. I will look at which strategies German speakers utilize to do so. I draw data from the popular German game show entitled " Wetten, dass..? " (Wanna bet that..?), where participants are asked to do a...

To achieve overall business goals, GQM+Strategies® is an approach that aligns the business goals at each level of an organization to strategies and assesses the achievement of goals. Strategies derived from business goals are based on rationales (context factors and assumptions). Because extracting all rationales is an important process in the GQM+Strategies approach, we propose Context-Assumpt...

Conservation tillage (CT) systems have a number of potential benefits including lower crop production costs and the ability to reduce soil erosion that have made them common in several regions of the world. Although CT systems have been researched and successfully implemented on some farms in California's San Joaquin Valley (SJV), overall adoption is low and the reasons for the region's compara...

corrective feedback (cf) and its different types have long absorbed many scholars and practitioners. as ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these cf techniques. the goal of this qualitative study was to discover whether the employment of different cf strategies could bring about an attitudinal shift. to...

Drawing on the insight from metacognition theory, second language researchers conceptualize strategic knowledge and strategic regulation as the two dimensions of strategic competence in language performance. In this regard, the present study aimed at determining whether strategic knowledge and strategic regulation are related to listening performance. The study also attempted to specify how str...
