Performance Feedback and Middle Managers’ Divergent Strategic Behavior

What drives middle managers to search for new strategic initiatives and champion them to top management? This behavior—labeled divergent strategic behavior—spawns emergent strategies and thereby provides one of the essential ingredients of strategic renewal. We conceptualize divergent strategic behavior as a response to performance feedback. Data from 123 senior middle managers overseeing 21 multi-country organizations (MCOs) of a Fortune 500 firm point to social performance comparisons rather than historical comparisons in driving divergent strategic behavior. Moreover, managers’ organizational identification affects whether they attend to organizational- or individual-level feedback. These results contribute to research on performance aspirations and strategy process by providing a multilevel, multidimensional framework of performance aspirations in middle management driven strategic renewal

One thousand plant transcriptomes and the phylogenomics of green plants

Abstract: Green plants (Viridiplantae) include around 450,000–500,000 species1, 2 of great diversity and have important roles in terrestrial and aquatic ecosystems. Here, as part of the One Thousand Plant Transcriptomes Initiative, we sequenced the vegetative transcriptomes of 1,124 species that span the diversity of plants in a broad sense (Archaeplastida), including green plants (Viridiplantae), glaucophytes (Glaucophyta) and red algae (Rhodophyta). Our analysis provides a robust phylogenomic framework for examining the evolution of green plants. Most inferred species relationships are well supported across multiple species tree and supermatrix analyses, but discordance among plastid and nuclear gene trees at a few important nodes highlights the complexity of plant genome evolution, including polyploidy, periods of rapid speciation, and extinction. Incomplete sorting of ancestral variation, polyploidization and massive expansions of gene families punctuate the evolutionary history of green plants. Notably, we find that large expansions of gene families preceded the origins of green plants, land plants and vascular plants, whereas whole-genome duplications are inferred to have occurred repeatedly throughout the evolution of flowering plants and ferns. The increasing availability of high-quality plant genome sequences and advances in functional genomics are enabling research on genome evolution across the green tree of life

The SPTPoL extended cluster survey

We describe the observations and resultant galaxy cluster catalog from the 2770 deg2 SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich (SZ) effect and confirmed with a combination of archival and targeted follow-up data, making particular use of data from the Dark Energy Survey (DES). With incomplete follow-up we have confirmed as clusters 244 of 266 candidates at a detection significance ξ ≥ 5 and an additional 204 systems at 4 4 threshold, and 10% of their measured SZ flux. We associate SZ-selected clusters, from both SPT-ECS and the SPT-SZ survey, with clusters from the DES redMaPPer sample, and we find an offset distribution between the SZ center and central galaxy in general agreement with previous work, though with a larger fraction of clusters with significant offsets. Adopting a fixed Planck-like cosmology, we measure the optical richness-SZ mass (l - M) relation and find it to be 28% shallower than that from a weak-lensing analysis of the DES data-a difference significant at the 4σ level-with the relations intersecting at λ = 60. The SPT-ECS cluster sample will be particularly useful for studying the evolution of massive clusters and, in combination with DES lensing observations and the SPT-SZ cluster sample, will be an important component of future cosmological analyses

Preliminary Results from the Software Product Management State-of-Practice Survey

Software product management (SPM) as a discipline includes many practices like product and release planning, market analysis, roadmapping, and product lifecycle management. Product management frameworks prescribe these practices but companies seldom adopt all of them. We conducted a state-of-practice survey with the aim to investigate how companies adopt SPM practices and how this practical experience fits together with the framework suggested by International Software Product Management Association (ISPMA). The results of this study showed that ISPMA SPM Framework describes core product management practices well but the impact of product management practices to the final product success remains ambiguous
