This study extends the upper echelons literature by shedding light on the role of top management team (TMT) dissimilarity, a specific conceptualization of team diversity. TMTs are typically composed of members from different functional areas who have unique information and values. The perception of the degree to which TMT members view themselves as dissimilar from other team members affects the TMT’s decision-making and, therefore, organizational outcomes. However, research does not address this perspective of TMT diversity. We examine how informational and value dissimilarity among TMT members is associated with incremental and radical innovation capability. We survey top managers from various industries and use partial least squares structural equation modeling analysis to explore the association between TMT dissimilarity and innovation capability empirically. The findings show that informational dissimilarity is positively associated with incremental innovation capability. Value dissimilarity is negatively associated with incremental innovation capability, whereas it is positively associated with radical innovation capability.

The aim of this experiment was to investigate the differential proteomic characteristics of milk from high- and low-yielding Guanzhong dairy goats during the peak lactation period under the same feeding conditions. Nine Guanzhong dairy goats with high yield (H: 3.5 ± 0.17 kg/d) and nine with low yield (L:1.2 ± 0.25 kg/d) were selected for milk proteomic analysis using tandem mass tag technology. A total of 78 differentially expressed proteins were identified. Compared with L, 50 proteins including HK3, HSPB1 and ANXA2 were significantly upregulated in H milk, while 28 proteins including LALBA and XDH were significantly downregulated. Bioinformatics analysis of the differentially expressed proteins showed that galactose metabolism, purine metabolism, glycolysis/gluconeogenesis, MAPK signaling pathway, regulation of actin cytoskeleton and other pathways were closely related to milk yield. HK3, HSPB1, ANXA2, LALBA and XDH were important candidate proteins associated with the milk production characteristics of Guanzhong dairy goats. Our data provide relevant biomarkers and a theoretical basis for improving milk production in Guanzhong dairy goats.

The relationship between managerial change and strategic change is a complex issue that challenges our understanding of how firms react to their business environment. In this study, we analyse the influence of the management team and more specifically their knowledge and capabilities in the process of strategic change. To do so, we delve deeper into the relationship between managerial change and strategic change by identifying the sequence of these changes. Using qualitative methodology, we analyse 10 companies listed on the Spanish Stock Exchange over an extensive period to formulate our propositions. Our analysis shows that managerial change precedes strategic change. Top management team reorganization, even without Chief Executive Officer succession, was a sufficient condition for strategic change to take place. Moreover, we identified key modifications that took place whenever strategic change occurred. Our results provide meaningful insights into the processes of strategic change within firms that broaden our theoretical knowledge in this area.
