Summary: Social capital can benefit organizations, but it can also hinder managers from responding promptly to emerging risks due to strong networks. Our study on U.S. listed firms during the financial crisis period shows that social capital reduces managers' perception of competition. This incomplete perception leads to low investment efficiency and poor firm performance during the crisis.

Summary: The study found that nostalgia for one's university past is linked to future engagement with the university, even if the university experience was not entirely positive. University belonging is an important mediator in the relationship between nostalgia and engagement.

Summary: This article investigates how boundary spanners create value in science-based SMEs through temporal sensemaking and the establishment of relationships. It explores the creation of social capital through boundary-spanning activities and demonstrates how effective boundary-spanning activities promote collaborations and support knowledge generation and innovation. The study highlights the importance of both retrospective and prospective sensemaking for generating new understandings and opportunities, and proposes an inductive model that frames the interplay between boundary-spanning activities, temporal sensemaking, and the generation of social capital as a knowledge resource for innovation and value creation.

Summary: This paper examines the economic determinants and political motivations of economic integration agreements. The author argues that economic integration can be used as a tool of foreign policy, where political factors influence the choice of contracting partners. The empirical findings support the hypothesis that there is more to economic integration than just trade, and geopolitical considerations play a determining role in the choice of contracting partner country and the depth of economic integration.

Summary: This study uses geo-coded panel data from the Netherlands Longitudinal Lifecourse Study to examine the relationship between perceptions of neighborhood social cohesion and immigrants' identification with the receiving society. The results show that high levels of perceived neighborhood social cohesion predict higher degrees of immigrants' national identification mainly through facilitating intergroup interaction.

Summary: White matter injury is a progressive vascular disease that can lead to neurological deficits and vascular dementia. Various pathologies may contribute to white matter injury, resulting in vascular dementia in the elderly population. Despite recent advancements, there are limited animal models for studying progressive subcortical white matter injury or vascular dementia, indicating the need for further research in this area.

Summary: White matter injury is a vascular disease that can lead to neurological deficits and vascular dementia. It can be caused by various pathologies, including small infarcts in deep penetrating blood vessels or the breakdown of endothelial function or the blood-brain barrier. White matter injury progresses and expands, resulting in cognitive and motor deficits, and is a major cause of vascular dementia in the elderly.

Summary: A widely accepted benefit of corporate political activities (CPA) is reducing a firm's overall uncertainty. However, CPA involves an exchange where firms give up strategic flexibility, which can be a burden for entrepreneurially oriented (EO) firms. We also investigate how the government's treatment of rival firms affects the calculus of CPA. Testing our hypotheses on S&P 1500 firms, we find support for our model.

Summary: The study highlights the benefits and challenges for Public Ancillary Funds (PubAFs) in dyadic partnerships, and how this relationship affects their identity, accountability, and independence. It shows significant differences between PubAFs in dyadic partnerships and those that are not. The closeness and exclusiveness of a dyadic partnership present both benefits and challenges to be actively managed by PubAFs.

Summary: Viruses are major pathogens of agricultural crops, but quantitative details of virus dynamics in plants are poorly understood. The authors studied the infection of individual cells in tobacco leaves and found that the pathways of viral dissemination and reasons for viral control may not be determined solely based on experimental measurements of virus infection in individual leaves.

Summary: This review summarizes the role of the protein kinase TOR in monitoring and regulating metabolism in eukaryotic cells, and discusses the mechanisms of amino acid sensing by TOR. By highlighting the diversity of amino acid sensors in human cells and pathways indirectly sensitive to amino acids, the authors explore the relevance of these findings to plant biology and suggest that TOR may sense both organic metabolites and inorganic nutrients.

Summary: mRNA translation is a crucial step in genome expression, and the target of rapamycin (TOR) plays a central regulatory role in eukaryotes. Recent studies have revealed that TOR regulates mRNA translation in plants through conserved signaling mechanisms and plant-specific pathways.

Summary: This study revealed the important roles of chloroplast redox response and stromule induction in hypersensitive response (HR) and resistance signaling. Chloroplast redox changes were found to play a significant role in signaling for resistance, and stromule induction was attenuated in plants with impaired salicylic acid (SA) accumulation.

Summary: The narrow odd dwarf (nod) and Liguleless narrow (Lgn) mutants in maize encode plasma membrane proteins and induce stress signaling pathways. Through protein interaction studies, we found that NOD interacts with LGN and that LGN can phosphorylate NOD. Mutants with combined Lgn-R and nod mutations exhibit more severe developmental defects and a shift in resource allocation. Our findings suggest that NOD and LGN act cumulatively to coordinate growth-defense tradeoffs in maize.

Summary: Higher plants generate new leaves from shoot meristems throughout their vegetative lifespan. The genetic signaling pathways that coordinate leaf initiation rate are not well understood. Two maize mutants, te1 and phyB1;phyB2, have opposite effects on leaf initiation rates and total leaf number at flowering time. By crossing these mutants and analyzing the resulting genotypes, it was found that te1 and phyB1;phyB2 likely control leaf initiation through distinct signaling pathways.

Summary: Central metabolism produces amino and fatty acids for seed value. The malic enzyme is active in multiple subcellular compartments, providing carbon for fatty acid biosynthesis in plants. This study confirms that increasing malic enzyme flux alters carbon partitioning and increases lipid levels in soybeans.

Summary: Viral synergism occurs when mixed infection of susceptible plants by multiple viruses increases susceptibility to at least one of the viruses. This study found that bean pod mottle virus disrupts soybean's extreme resistance against soybean mosaic virus by impairing the downstream defense mechanism induced by the Rsv3 R gene.

Summary: The TOR protein kinase in plants regulates nucleotide synthesis and metabolic balance by promoting the activity of cytosolic phosphoribosyl pyrophosphate synthetase (PRS4). Knockout of the prs4 gene leads to embryo lethality in Arabidopsis, while silencing of PRS4 expression causes various developmental abnormalities in Nicotiana benthamiana.
