On the Characteristics of Internal Software Startups

In recent years, more attention has been given to internal software startups in practice and in research alike, yet the concept is not fully understood. Nor is it clear whether or not it significantly differs from stand-alone software startup, and if yes, then how. In this position paper, we propose to conceptualize internal software startups as a hybrid of two related concepts: stand-alone software startup and internal corporate venture (ICV). We derive characteristics of the both concepts from the earlier literature and use our previous research on internal software startups to uncover the differences and the similarities across the three concepts.publishedVersio

Psychological Safety in Agile Software Development Teams: Work Design Antecedents and Performance Consequences

Psychological safety has been postulated as a key factor for the success of agile software development teams, yet there is a lack of empirical studies investigating the role of psychological safety in this context. This study examines how work design characteristics of software development teams (autonomy, task interdependence and role clarity) influence psychological safety and further how psychological safety impacts team performance, either directly or indirectly through team reflexivity. We test our model using survey data from 236 team members in 43 software development teams in Norway. Our results show that autonomy boosts psychological safety in software teams and that psychological safety again has positive effect on team reflexivity and a direct effect on team performance

The Agile Coach Role: Coaching for Agile Performance Impact

It is increasingly common to introduce agile coaches to help gain speed and advantage in agile companies. Following the success of Spotify, the role of the agile coach has branched out in terms of tasks and responsibilities, but little research has been conducted to examine how this role is practiced. This paper examines the role of the agile coach through 19 semi-structured interviews with agile coaches from ten different companies. We describe the role in terms of the tasks the coach has in agile projects, valuable traits, skills, tools, and the enablers of agile coaching. Our findings indicate that agile coaches perform at the team and organizational levels. They affect effort, strategies, knowledge, and skills of the agile teams. The most essential traits of an agile coach are being emphatic, people-oriented, able to listen, diplomatic, and persistent. We suggest empirically based advice for agile coaching, for example companies giving their agile coaches the authority to implement the required organizational changes within and outside the teams

Work Engagement in Agile Teams: The Missing Link Between Team Autonomy, Trust, and Performance?

To have engaged and high-performing agile teams are what most organizations strive for. At the same time, there is little research on the drivers of team work engagement in the software context. Team autonomy and trust are crucial for agile teams and are suggested as potential boosters of team work engagement and performance. In this study, we apply the Job Demands-Resources model to examine the role of autonomy and trust and their impact on work engagement and team performance in agile teams. We analyze quantitative survey data from 236 team members in 43 agile teams to examine how team autonomy and trust relate to team work engagement and how engagement mediates the relationship between these factors and performance. Our results show that while both autonomy and trust are positively related to team work engagement, team trust plays a more critical role than team autonomy. Teams with high team trust showed higher engagement, which enhanced team performance. Our results highlight the importance of social factors such as trust in creating conditions for high performance in agile teams through its effect on team work engagement.publishedVersio

Regime shift of the South China Sea SST in the late 1990s

Decadal variability of the South China Sea (SCS) sea surface temperature (SST) during 1982–2014 is investigated using observations and ocean reanalysis datasets. The SCS SST shows an abrupt transition from a cold-to-warm regime in the late 1990s. Based on the long-term SST variability two epochs are defined, 1982–1996 and 2000–2014 as cold and warm regimes respectively, spanning on either side of the 1997–1999 SCS warming. Despite the occurrence of strong El Nino induced warming events, the SST anomalies tend to be negative in the cold regime. Conversely during the warm regime, the positive SST anomalies have dominated over the La Nina driven cooling events. The cold (warm) SST regime is marked by net heat gain (loss) by the SCS. The long-term variations of net surface heat flux are mainly driven by the latent heat flux anomalies while the short wave flux plays a secondary role. Low-frequency variability of the South China Sea throughflow (SCSTF) appears to be closely related to the SCS SST regime shift. The SCSTF shows reversing trends during the cold and warm epochs. The weakened SCSTF in the warm regime has promoted the SCS warming by limiting the outward flow of warm water from the SCS. Meanwhile, enhanced SCSTF during the cold regime acts as a cooling mechanism and lead to persistent negative SST anomalies. The change in trend of the SCSTF and SST regime shift coincides with the switching of pacific decadal oscillation from a warm to cold phase in the late 1990s.Singapore.

Мета дослідження – вивчити особливості діагностики та лікування катаменіального пневмотораксу (КП). Матеріали та методи. Пацієнтка віком 33 р. перебувала на лікуванні в КМКЛ № 17 з 12.07.13 по 16.07.13 та з 21.08.13 по 02.09.13. Їй проводили повний клініко-діагностичний комплекс обстежень та лікування відповідно до діючих протоколів. Результати дослідження та їх обговорення. У статті представлено огляд літератури з питання КП та подано опис клінічного випадку, а також узагальнено особливості діагностики та лікування КП. Сучасні міні-інвазивні способи хірургічних втручань та раціональна консервативна терапія є методом вибору в діагностиці та лікуванні КП. Всебічне дообстеження є необхідною передумовою для вибору раціональної тактики подальшого лікування. Консенсусу щодо оптимальних доз та строків гормональної терапії дотепер не досягнуто. Висновки. До сьогодні ендометріоз залишається малодослідженим захворюванням, а його поширеність у світовій популяції досягає 11 %. Оптимальні результати лікування досягаються за умови комплексного підходу із залученням суміжних фахівців, у т. ч. гінекологів

The Various Components of the Circulation in the Singapore Strait Region: Tidal, Wind and Eddy-driven Circulations and Their Relative Importance

To obtain a better understanding of environment-related physical oceanography in Singapore Strait Region, numerical experiments are implemented to study the circulation in SSR. The three important components, tidal, wind and eddy-driven circulations are identified. It is shown that the tidal circulation is dominant in the region. Even though the wind and eddy circulations are relatively small, they may have significant effect on the local circulation and material transport.Singapore-MIT Alliance.
