Effective communication in globally distributed Scrum teams

Trends in information systems development include the use of globally distributed teams and agile methodologies such as Scrum. Globally distributed (GD) software development challenges team communication. Before we can evaluate effective communication in GD teams using Scrum, we need to know what effective communication means in that context. This study captures the understanding of effective communication based on interviews with industry professionals working in GD Scrum teams and reports on Scrum practices that keep communication effective. From these interviews, we developed a model consisting of communication transparency, communication quality, and communication discipline, leading to the alignment of team understanding. This paper contributes to practitioners’ knowledge about what effective communication means in GD Scrum and describes tools that support communication. The theoretical contribution of the study is a model of effective communication that lays the ground for future research on evaluating Scrum’s effect on communication in GD contexts

Effective Communication in Globally Distributed Scrum: A Model and Practical Guidance

A trend in information systems development is for globally distributed teams to use agile methods and frameworks such as Scrum. In globally distributed (GD) software development, a known challenge is effective team communication. Researchers, however, cannot evaluate effective communication in GD teams using Scrum unless they know what effective communication means in that context. This qualitative study contributes a theoretical model of effective communication in GD Scrum teams and practical guidance for practitioners. Ten industry professionals working in GD Scrum teams were interviewed to capture their understanding of effective communication. Qualitative content analysis was used to analyse the interviews and form a basis for the model and the practical guidance. This novel model consists of communication transparency, communication quality, and communication discipline, which together lead to the alignment of team understanding (i.e., a team-level shared mental model). This theoretical model lays the ground for future research into the effect of Scrum practices on communication in GD contexts, and the effect of communication on team and project success. For practitioners, this study contributes 11 practical actions that professionals recommend for improving and sustaining effective communication

Plenary Speakers: Downstream Migration of Fish in Regulated Rivers: Patterns and Mechanisms

Dmitrii Pavlov graduated from the Moscow State University, Dept. of Ichthyology, in 1960 where currently he is a Head of the Department. His main study area covers fish behavior and ecology, and the behavior of fishes including orientation, locomotion, and migrations in the water flow. He has been studying patterns and mechanisms of downstream migrations in the field and in laboratory experiments since 1962. His field studies, with the main focus on down-stream migration through dams have been carried out in many rivers of Europe, Asia, Africa, and South America. Field programs were complemented with experimental studies on behavior, morphology, physiology, and biochemical traits of migrants. Dmitrii Pavlov has written several books and many papers on down-stream migration of young fish, control of their behavior in the water flow, and the protection of migrating fish in regulated rivers. Dmitrii Pavlov is a member of the Russian Academy of Sciences, and the Lithuanian Academy of Sciences. Drs. Victor Mikheev and Vasilii Kostin, co-authors of the plenary talk for FP2015, have been working together with Dmitrii Pavlov in the field of fish behavior and ecology since 1981. Dr Mikheev presented on Prof Pavlov’s behalf

Selective Removal of Fish from Reservoirs and Lakes: Interaction of Hydraulic and Ecological Factors

Downstream migration (DSM) of fish through the different types of water intakes is not a random process, but rather a selective removal from the limnetic to the lotic parts of river–lake systems. Selectivity means that the assemblage of migrants does not exactly reflect the composition of the fish community in an upstream reservoir. Some fish are more prone to migrate compared to others, but this is not the only factor affecting DSM. We hypothesize that the interaction of a 3-D “hydraulic funnel” at the water intake with adjacent ecological zones results in the selective removal of fish. We tested our predictions by analyzing the data on DSM and spatial distribution in 13 reservoirs and lakes in Europe and Asia. Water intakes were surrounded by different habitats and located at different depths, from the surface layer to the depth of more than 50 m. Most vulnerable for entrainment by the outflow were the inhabitants of the pelagic zone. The share of fish emigrating from the littoral habitats was much lower compared to pelagic inhabitants. This suggests that littoral habitats saturated with landmarks and shelters hamper DSM more than the vertical physical gradients in the pelagic do. In conjunction with the factors operating on the scale of the whole reservoir, hydro-ecological barriers of different types associated with water intakes play an important role in the selective removal of fish from reservoirs and lakes

Smooth Muscle Actin as a Criterion for Gravisensitivity of Stomach and Jejunum in Laboratory Rodents

Smooth muscle tissue (SMT) is one of the main structural components of visceral organs, acting as a key factor in the development of adaptive and pathological conditions. Despite the crucial part of SMT in the gastrointestinal tract activity, the mechanisms of its gravisensitivity are still insufficiently studied. The study evaluated the content of smooth muscle actin (α-SMA) in the membranes of the gastric fundus and jejunum in C57BL/6N mice (30-day space flight), in Mongolian gerbils Meriones unguiculatus (12-day orbital flight) and after anti-orthostatic suspension according to E.R. Morey-Holton. A morphometric analysis of α-SMA in the muscularis externa of the stomach and jejunum of mice and Mongolian gerbils from space flight groups revealed a decreased area of the immunopositive regions, a fact indicating a weakening of the SMT functional activity. Gravisensitivity of the contractile structures of the digestive system may be due to changes in the myofilament structural components of the smooth myocytes or myofibroblast actin. A simulated antiorthostatic suspension revealed no significant changes in the content of the α-SMA expression level, a fact supporting an alteration in the functional properties of the muscularis externa of the digestive hollow organs under weightless environment. The data obtained contribute to the novel mechanisms of the SMT contractile apparatus remodeling during orbital flights and can be used to improve preventive measures in space biomedicine
