Cohesion or confusion? Towards a typology for organizational learning research

The study of organizational learning is no longer in its infancy. Since Cyert and March first introduced the notion in the early 1960s, a plethora of books and journal publications have presented their own interpretations of the meaning and significance of the term. Despite such endeavours, there is little common agreement about what organizational learning represents and how future research may build cumulatively upon the many diverse ideas articulated. The intention here is by no means to address these issues, which have been comprehensively examined elsewhere. The purpose is rather to compare and contrast approaches in order to analyse similarities and dissimilarities, together with research challenges, for each approach. This is achieved by presenting a comparative framework to categorize the literature according to (a) its prescriptive/explanatory bias and (b) in line with the level of analysis, examining whether there is a focus on the organization as a whole or upon individuals and their work communities instead. The review concludes by presenting some preliminary suggestions for cross-quadrant research. © Blackwell Publishing Ltd 2006.

Cohesion in text differentiation : a study of English and Arabic

This thesis sets out to investigate the role of cohesion in the organisation and processing of three text types in English and Arabic. In other words, it attempts to shed some light on the descriptive and explanatory power of cohesion in different text typologies. To this effect, three text types, namely, literary fictional narrative, newspaper editorial and science were analysed to ascertain the intra- and inter-sentential trends in textual cohesion characteristic of each text type in each language. In addition, two small scale experiments which aimed at exploring the facilitatory effect of one cohesive device (i.e. lexical repetition) on the comprehension of three English text types by Arab learners were carried out. The first experiment examined this effect in an English science text; the second covered three English text types, i.e. fictional narrative, culturally-oriented and science. Some interesting and significant results have emerged from the textual analysis and the pilot studies. Most importantly, each text type tends to utilize the cohesive trends that are compatible with its readership, reader knowledge, reading style and pedagogical purpose. Whereas fictional narratives largely cohere through pronominal co-reference, editorials and science texts derive much cohesion from lexical repetition. As for cross-language differences English opts for economy in the use of cohesive devices, while Arabic largely coheres through the redundant effect created by the high frequency of most of those devices. Thus, cohesion is proved to be a variable rather than a homogeneous phenomenon which is dictated by text type among other factors. The results of the experiments suggest that lexical repetition does facilitate the comprehension of English texts by Arab learners. Fictional narratives are found to be easier to process and understand than expository texts. Consequently, cohesion can assist in the processing of text as it can in its creation.

The relationship between transformational leadership and innovative behaviour in a healthcare context:a team learning versus a cohesion perspective

The purpose of this study was to explore whether the relationship between transformational leadership and innovative behaviour is explained via the mediating role of team learning, or whether instead team cohesion mediates this relationship. Using survey data from 158 professionals within 21 teams in the Dutch healthcare context, we tested by means of hierarchical regression analyses: (a) the relationship between transformational leadership and innovative behaviour; (b) whether team learning or cohesion mediates this relationship; and (c) the relationship between team learning and cohesion, in relation to transformational leadership. Results showed that transformational leadership is positively related to innovative behaviour and that both cohesion and team learning mediate this relationship, with team learning being the strongest mediator. Addressing a neglected area, our study provides evidence to show that managers who enhance team learning are likely to maximise employees' scope for engaging in innovative behaviours. © 2012 Inderscience Enterprises Ltd.

Comparative analysis of experimental and modelling of gas-solid flow hydrodynamics:effect of friction and interparticle cohesion forces

The effect of friction and interparticle cohesion forces on the gas-solid flow hydrodynamics was discussed. A proposed interparticle cohesion and frictional force terms have been tested in a continuum fully developed flow model to investigate their effect on the general hydrodynamic features of vertical duct flow. It was observed that both terms have direct effect on lowering the material carryover, which implies a reduced bed expansion in freely bubbling column. The parametric analysis shows that cohesion and frictional forces are high when compared to kinetic stress and hence it can play a major role in describing the hydrodynamics features of the flow.

A Sensitive Metric of Class Cohesion

Metrics estimate the quality of different aspects of software. In particular, cohesion indicates how well the parts of a system hold together. A metric to evaluate class cohesion is important in object-oriented programming because it gives an indication of a good design of classes. There are several proposals of metrics for class cohesion but they have several problems (for instance, low discrimination). In this paper, a new metric to evaluate class cohesion is proposed, called SCOM, which has several relevant features. It has an intuitive and analytical formulation, what is necessary to apply it to large-size software systems. It is normalized to produce values in the range [0..1], thus yielding meaningful values. It is also more sensitive than those previously reported in the literature. The attributes and methods used to evaluate SCOM are unambiguously stated. SCOM has an analytical threshold, which is a very useful but rare feature in software metrics. We assess the metric with several sample cases, showing that it gives more sensitive values than other well know cohesion metrics.

Developing community and social cohesion through grassroots bridge-building: an exploration

In the context of the UK public policy goal to increase community and social cohesion, this article explores the nature of local 'bridge-building' – activities intended to increase interpersonal contacts between diverse ethnic, faith and nationality groups. We draw on earlier research in a range of fields to develop the bridge-building concept and present findings from a study that identified community-level projects with bridge-building as a specific aim. We show the range of groupings involved, the activities encompassed and their organisational features. We consider the actual and potential contribution of local bridge-building to cohesion in the light of earlier research and our own study.

A kohéziós politika hatékonysága (The efficiency of cohesion policy)

A kohéziós politika hatékonyságát, eredményességét és szabályszerűségét a nemzetállami szint mellett közösségi szinten is értelmezhetjük. Azonban a közösségi szint nem a tagállami részek összege, hanem annál sokkal jelentősebb. Ha a közösségi szinten nem támasztható alá a kohéziós politika szükségszerűsége, akkor annak költségvetése és ezáltal jelentősége az EU következő pénzügyi perspektívájában csökkenhet, amelynek súlyos kihatásai lennének a tagállamok és régióik közötti kohéziós folyamatokra. Éppen ezért fontos a kohéziós politika objektív és részletes elemzése tagállami szinten, valamint a közösségi szintű kohéziós politika kritikáinak és a különböző reformelképzeléseknek vizsgálata. / === / The efficiency, effectiveness and regularity of cohesion policy can be defined both on the community level and on the national level. But the community level more than the sum of the member states. If the necessity of the cohesion policy cannot be backed sufficiently, then its budget of the policy can be decreased in the next financial framework of the EU. This could deeply undermine the process of convergence of the less developed regions of the member states. This is why the objective and detailed analysis of the cohesion policy is important, together with knowing the criticisms and reform proposals of the community level cohesion policy.
