Lexical Cohesion is a commonly studied linguistic feature as it is easily identified from the surface of a text. However, the purposes for studying lexical cohesion are varied, and each purpose requires different methods. This study analyzes two short movie review texts for four different research purposes using lexical cohesion: text evaluation, text segmentation, text summarization, and text ...
In this work, we explore the feasibility of regulating the collective behavior of zebrafish with a free-swimming robotic fish. The visual cues elicited by the robot are inspired by salient features of attraction in zebrafish and include enhanced coloration, aspect ratio of a fertile female, and carangiform/subcarangiform locomotion. The robot is autonomously controlled with an online multi-targ...
Decision-making theories explain animal behaviour, including human behaviour, as a response to estimations about the environment. In the case of collective behaviour, they have given quantitative predictions of how animals follow the majority option. However, they have so far failed to explain that in some species and contexts social cohesion increases when conditions become more adverse (i.e. ...
We identify a unique viewpoint on the collective behaviour of intelligent agents. We first develop a highly general abstract model for the possible future lives these agents may encounter as a result of their decisions. In the context of these possibilities, we show that the causal entropic principle, whereby agents follow behavioural rules that maximize their entropy over all paths through the...
Purpose – According to one influential set of arguments, the privatization of public pensions has been informed by neoliberalism, and has thus been an integral element of a broader program of welfare retrenchment, which is inconsistent with social cohesion. The paper aims to take issue with this negative characterization of pensions privatization. Design/methodology/approach – The argument is i...
The study of new media use by transnational social movements is central to contemporary investigations of social contention. In order to shed light on the terrain in which the most recent examples of online mobilization have grown and developed, this paper combines the interest in the transnational dynamics of social contention and the exploration of the use of new ICTs for protest action. In s...
From the early literature on the role of firm managers (Alchian and Demsetz 1972) to the industrial organisation on contracts and mechanism design (Laffont and Martimort 2009), economists have given a lot of attention to find solutions to the imperfect alignment between individuals’ incentives and an organisation’s collective goals (Prendergast 1999). In that literature a key role of managers i...
Migrating cells need to overcome physical constraints from the local microenvironment to navigate their way through tissues. Cells that move collectively have the additional challenge of negotiating complex environments in vivo while maintaining cohesion of the group as a whole. The mechanisms by which collectives maintain a migratory morphology while resisting physical constraints from the sur...
Overall health surveys have related family cohesion to socio-economic status and behavioral factors. The scope of this study was to investigate the association between family cohesion and socio-economic, behavioral and oral health factors. This was a, cross-sectional study with two-stage cluster sampling. The random sample consisted of 524 adolescents attending public schools in the city of Pir...
Class cohesion is a key object-oriented software quality attribute. It refers to the degree of relatedness of class attributes and methods. Several class cohesion metrics are proposed in the literature. However, the impact of considering the special methods (i.e., constructors, destructors, and access and delegation methods) in cohesion calculation is not thoroughly theoretically studied for mo...
