Sequences of Learning Types for Organizational Ambidexterity

Ambidexterity involves strategies for effectively managing the inherent tensions between short-term stability and long-term investments, a challenge known as the exploitation-exploration paradox. Despite the acknowledged importance of learning in the context of ambidexterity, there is a limited understanding of how various forms of organizational learning are employed over time in projects focused on either exploitation or exploration. This gap in knowledge is significant because the timing and sources of knowledge acquisition that support innovation can significantly impact the success of an ambidextrous approach. In essence, ambidexterity not only requires balancing the conflicting demands of exploitation and exploration but also necessitates the integration of both internal and external knowledge sources.https://dc.suffolk.edu/ciclseries/1002/thumbnail.jp

Draft genome sequence of Pseudomonas syringae pathovar syringae strain FF5, causal agent of stem tip dieback disease on ornamental pear.

addresses: The Sainsbury Laboratory, John Innes Centre, Norwich, United Kingdom.notes: PMCID: PMC3393499types: Journal Article; Research Support, Non-U.S. Gov'tFree on Open AccessPseudomonas syringae FF5 causes stem tip dieback disease on ornamental pear (Pyrus calleryana). Its genome encodes a complete type III secretion system (T3SS) and HopAC1, HopM1, AvrE1, HopI1, HopAA1, HopJ1, HopAH2, HopAH1, HopAG1, and HopAZ1. Lacking detectable homologues of other T3SS effectors, it may encode novel, undiscovered effectors

Neuromapping: Inflight Evaluation of Cognition and Adaptability

In consideration of the health and performance of crewmembers during flight and postflight, we are conducting a controlled prospective longitudinal study to investigate the effects of spaceflight on the extent, longevity and neural bases of sensorimotor, cognitive, and neural changes. Previous studies investigating sensorimotor adaptation to the microgravity environment longitudinally inflight have shown reduction in the ability to perform complex dual tasks. In this study we perform a series of tests investigating the longitudinal effects of adaptation to the microgravity environment and how it affects spatial cognition, manual visuo-motor adaption and dual tasking

Bulk Damage Effects in Irradiated Silicon Detectors due to Clustered Divacancies

High resistivity silicon particle detectors will be used extensively in experiments at the future CERN Large Hadron Collider where the enormous particle fluences give rise to significant atomic displacement damage. A model has been developed to estimate the evolution of defect concentrations during irradiation and their electrical behaviour according to Shockley-Read-Hall (SRH) semiconductor statistics. The observed increases in leakage current and doping concentration changes can be described well after gamma irradiation but less well after fast neutron irradiation. A possible non-SRH mechanism is considered, based on the hypothesis of charge transfer between clustered divacancy defects in neutron damaged silicon detectors. This leads to a large enhancement over the SRH prediction for V2 acceptor state occupancy and carrier generation rate which may resolve the discrepancy

Towards a 21st-century roadmap for biomedical research and drug discovery:consensus report and recommendations

Decades of costly failures in translating drug candidates from preclinical disease models to human therapeutic use warrant reconsideration of the priority placed on animal models in biomedical research. Following an international workshop attended by experts from academia, government institutions, research funding bodies, and the corporate and nongovernmental organisation (NGO) sectors, in this consensus report, we analyse, as case studies, five disease areas with major unmet needs for new treatments. In view of the scientifically driven transition towards a human pathway-based paradigm in toxicology, a similar paradigm shift appears to be justified in biomedical research. There is a pressing need for an approach that strategically implements advanced, human biology-based models and tools to understand disease pathways at multiple biological scales. We present recommendations to help achieve this

Lessons from Toxicology: Developing a 21st‑Century Paradigm for Medical Research

Biomedical developments in the 21st century provide an unprecedented opportunity to gain a dynamic systems-level and human-specific understanding of the causes and pathophysiologies of disease. This understanding is a vital need, in view of continuing failures in health research, drug discovery, and clinical translation. The full potential of advanced approaches may not be achieved within a 20th-century conceptual framework dominated by animal models. Novel technologies are being integrated into environmental health research and are also applicable to disease research, but these advances need a new medical research and drug discovery paradigm to gain maximal benefits. We suggest a new conceptual framework that repurposes the 21st-century transition underway in toxicology. Human disease should be conceived as resulting from integrated extrinsic and intrinsic causes, with research focused on modern human-specific models to understand disease pathways at multiple biological levels that are analogous to adverse outcome pathways in toxicology. Systems biology tools should be used to integrate and interpret data about disease causation and pathophysiology. Such an approach promises progress in overcoming the current roadblocks to understanding human disease and successful drug discovery and translation. A discourse should begin now to identify and consider the many challenges and questions that need to be solved

Clinical and Molecular Characterization of Ataxia with Oculomotor Apraxia Patients In Saudi Arabia

<p>Abstract</p> <p>Background</p> <p>Autosomal recessive ataxias represent a group of clinically overlapping disorders. These include ataxia with oculomotor apraxia type1 (AOA1), ataxia with oculomotor apraxia type 2 (AOA2) and ataxia-telangiectasia-like disease (ATLD). Patients are mainly characterized by cerebellar ataxia and oculomotor apraxia. Although these forms are not quite distinctive phenotypically, different genes have been linked to these disorders. Mutations in the <it>APTX </it>gene were reported in AOA1 patients, mutations in <it>SETX </it>gene were reported in patients with AOA2 and mutations in <it>MRE11 </it>were identified in ATLD patients. In the present study we describe in detail the clinical features and results of genetic analysis of 9 patients from 4 Saudi families with ataxia and oculomotor apraxia.</p> <p>Methods</p> <p>This study was conducted in the period between 2005-2010 to clinically and molecularly characterize patients with AOA phenotype. Comprehensive sequencing of all coding exons of previously reported genes related to this disorder (<it>APTX</it>, <it>SETX </it>and <it>MRE11</it>).</p> <p>Results</p> <p>A novel nonsense truncating mutation c.6859 C > T, R2287X in <it>SETX </it>gene was identified in patients from one family with AOA2. The previously reported missense mutation W210C in <it>MRE11 </it>gene was identified in two families with autosomal recessive ataxia and oculomotor apraxia.</p> <p>Conclusion</p> <p>Mutations in <it>APTX </it>, <it>SETX </it>and <it>MRE11 </it>are common in patients with autosomal recessive ataxia and oculomotor apraxia. The results of the comprehensive screening of these genes in 4 Saudi families identified mutations in <it>SETX </it>and <it>MRE11 </it>genes but failed to identify mutations in <it>APTX </it>gene.</p
