Software metrics are used to check and evaluate various aspects of the complexity of a software product. Coupling and Cohesion are considered to be the most important attributes. The increasing need for software quality measurements has led to extensive research into software metrics and the development of software metric tools. Many Software Metrics have been proposed for object oriented parad...

The process of Sister Chromosome Cohesion (SCC), which holds together sister chromatids upon replication, is essential for chromosome segregation and DNA repair in eukaryotic cells. Although cohesion at the molecular level has never been described in E. coli, previous studies have reported that sister sequences remain co-localized for a period after their replication. Here, we have developed a ...

Relationships among a modifiable situational factor (unit cohesion), prior stressful life events, and posttraumatic stress disorder (PTSD) symptoms were assessed in 1,579 U.S. Army soldiers with no history of contemporary war zone deployment. It was predicted that unit cohesion would attenuate the dose-response relationship between past stressor exposures and PTSD symptoms at relatively moderat...

Class cohesion is an important object-oriented software quality attribute. It indicates how much the members in a class are related. Assessing the class cohesion and improving the class quality accordingly during the object-oriented design phase allows for cheaper management of the later phases. In this paper, the notion of distance between pairs of methods and pairs of attribute types in a cla...

The present investigation undertook a large-scale replication of an apparently successful group cohesion manipulation reported by Etringer, Gregory, and Lando (1984)l A 2 x 2 factorial design was initiated in which subjects were to be randomly assigned to enriched or standard cohesion and to satiation or nicotine fading. However, subject resistance to the satiation technique necessitated the ab...

Previous meta-analytic examinations of group cohesion and performance have focused primarily on contextual factors. This study examined issues relevant to applied researchers by providing a more detailed analysis of the criterion domain. In addition, the authors reinvestigated the role of components of cohesion using more modern meta-analytic methods and in light of different types of performan...

Accurate genome segregation depends on cohesion mechanisms that link duplicated sister chromatids, thereby allowing their tension-dependent biorientation in metaphase. In Saccharomyces cerevisiae, cohesion is established during DNA replication when Eco1 acetylates the cohesin subunit Smc3. Cohesion establishment is restricted to S phase of the cell cycle, but the molecular basis of this regulat...

Pds5 and Wpl1 act as anti-establishment factors preventing sister-chromatid cohesion until counteracted in S-phase by the cohesin acetyl-transferase Eso1. However, Pds5 is also required to maintain sister-chromatid cohesion in G2. Here, we show that Pds5 is essential for cohesin acetylation by Eso1 and ensures the maintenance of cohesion by promoting a stable cohesin interaction with replicated...

W e use program slices to model module cohesion. For our purposes, a slice is a projection of program text that includes only the data tokens relevant t o one output. W e define six cohesion metrics in terms of these slices, and evaluate the effects of classes of module changes on these metrics. W e find that the effects on cohesion metrics are notably more predictable when the changes result f...

In this paper, we consider the effect of cohesion on the stability of a granular heap and compute the maximum angle of stability of the heap as a function of the cohesion. We show that the stability is strongly affected by the dependence of the cohesion on the local pressure. In particular, this dependence is found to determine the localization of the failure plane. While for a constant adhesio...
