The quality of the software design has a considerable impact on software maintainability. Improving software quality can reduce costs and efforts of software maintenance. Cohesion, as one of software quality characteristics, can be used as an early indicator for predicting software maintenance efforts. This paper improves Martin’s cohesion metric, which is one of the well-known and wellaccepted...

A hypothesis to explain the maternal age-dependent increase in formation of aneuploid eggs is deterioration of chromosome cohesion. Although several lines of evidence are consistent with this hypothesis, whether cohesion is actually reduced in naturally aged oocytes has not been directly tested by any experimental perturbation. To directly target cohesion, we increased the activity of separase,...

Replicated sister chromatids are held together until mitosis by cohesin, a conserved multisubunit complex comprised of Smc1, Smc3, Scc1, and Scc3, which in vertebrate cells exists as two closely related homologues (SA1 and SA2). Here, we show that cohesin(SA1) and cohesin(SA2) are differentially required for telomere and centromere cohesion, respectively. Cells deficient in SA1 are unable to es...

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 ...

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...

OBJECTIVE The aim of this study was to review literature relevant to cohesion measurement, explore developing measurement approaches, and provide theoretical and practical recommendations for optimizing cohesion measurement. BACKGROUND Cohesion is essential for team effectiveness and performance, leading researchers to focus attention on understanding how to enhance it. However, cohesion is i...

Context: Class cohesion is an important object-oriented software quality attribute. Assessing class cohesion during the object-oriented design phase is one important way to obtain more comprehensible and maintainable software. In practice, assessing and controlling cohesion in large systems implies measuring it automatically. One issue with the few existing cohesion metrics targeted at the high...

We explored the possibility of predicting learners’ affective states (boredom, flow/engagement, confusion, and frustration) by monitoring variations in the cohesiveness of tutorial dialogues during interactions with AutoTutor, an intelligent tutoring system with conversational dialogues. Multiple measures of cohesion (e.g., pronouns, connectives, semantic overlap, causal cohesion, coreference) ...
