Social insects are important models for social evolution and behavior. However, in many species, experimental control over important factors that regulate division of labor, such as genotype and age, is limited. Furthermore, most species have fixed queen and worker castes, making it difficult to establish causality between the molecular mechanisms that underlie reproductive division of labor, t...

Using the agent based simulation model Sociodynamica, I explore the effect of various intensities of feelings of shame in cementing social bonds that affect the aggregate health (average longevity of agents) and wealth (GDP) of two artificial societies: A primitive society with no division of labor, and a monetized society with division of labor for three different tasks. The results show that ...

Insect life strategies comprise all levels of sociality from solitary to eusocial, in which individuals form persistent groups and divide labor. With increasing social complexity, the need to communicate a greater diversity of messages arose to coordinate division of labor, group cohesion, and concerted actions. Here we summarize the knowledge on prominent messages in social insects that inform...

the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...

Division of labor is a striking feature observed in honey bees and many other social insects. Division of labor has been claimed to benefit fitness. In honey bees, the adult work force may be viewed as divided between non-foraging hive bees that rear brood and maintain the nest, and foragers that collect food outside the nest. Honey bee brood pheromone is a larval pheromone that serves as an ex...

Market-based algorithms have been introduced several years ago (Kurose & Simha, 1989; Waldspurger et al., 1992; Huberman & Hogg, 1995; Clearwater & Huberman, 1994; Clearwater,1995; Wellman, 1993, 1995; Ykke et al., 1997; Ykke, 1998) as a new paradigm for controlling complex, unpredictable systems. In a market-based algorithm, resources or tasks are allocated efficiently through a market-clearin...
