    Organizational Learning and the Marine Corps: The Counterinsurgency Campaign in Iraq

    Organizational Learning and the Marine Corps: The Counterinsurgency Campaign in Iraq examines how the U.S. Marine Corps was able to learn from and adapt to conditions on the ground in Anbar province from 2006–2008 and develop a three-dimensional strategy that resulted in stability. Dr. Richard Shultz views this success through the lens of organizational theory, arguing that the Marine Corps’ organizational culture underscores learning and embeds lessons from its history into the Corps memory.https://digital-commons.usnwc.edu/ciwag-case-studies/1000/thumbnail.jp

    Humanized Mouse Model of Ovarian Cancer Recapitulates Patient Solid Tumor Progression, Ascites Formation, and Metastasis

    Ovarian cancer is the most common cause of death from gynecological cancer. Understanding the biology of this disease, particularly how tumor-associated lymphocytes and fibroblasts contribute to the progression and metastasis of the tumor, has been impeded by the lack of a suitable tumor xenograft model. We report a simple and reproducible system in which the tumor and tumor stroma are successfully engrafted into NOD-scid IL2RÎłnull (NSG) mice. This is achieved by injecting tumor cell aggregates derived from fresh ovarian tumor biopsy tissues (including tumor cells, and tumor-associated lymphocytes and fibroblasts) i.p. into NSG mice. Tumor progression in these mice closely parallels many of the events that are observed in ovarian cancer patients. Tumors establish in the omentum, ovaries, liver, spleen, uterus, and pancreas. Tumor growth is initially very slow and progressive within the peritoneal cavity with an ultimate development of tumor ascites, spontaneous metastasis to the lung, increasing serum and ascites levels of CA125, and the retention of tumor-associated human fibroblasts and lymphocytes that remain functional and responsive to cytokines for prolonged periods. With this model one will be able to determine how fibroblasts and lymphocytes within the tumor microenvironment may contribute to tumor growth and metastasis, and will make it possible to evaluate the efficacy of therapies that are designed to target these cells in the tumor stroma

    Patient-derived xenograft (PDX) models in basic and translational breast cancer research

    Patient-derived xenograft (PDX) models of a growing spectrum of cancers are rapidly supplanting long-established traditional cell lines as preferred models for conducting basic and translational preclinical research. In breast cancer, to complement the now curated collection of approximately 45 long-established human breast cancer cell lines, a newly formed consortium of academic laboratories, currently from Europe, Australia, and North America, herein summarizes data on over 500 stably transplantable PDX models representing all three clinical subtypes of breast cancer (ER+, HER2+, and "Triple-negative" (TNBC)). Many of these models are well-characterized with respect to genomic, transcriptomic, and proteomic features, metastatic behavior, and treatment response to a variety of standard-of-care and experimental therapeutics. These stably transplantable PDX lines are generally available for dissemination to laboratories conducting translational research, and contact information for each collection is provided. This review summarizes current experiences related to PDX generation across participating groups, efforts to develop data standards for annotation and dissemination of patient clinical information that does not compromise patient privacy, efforts to develop complementary data standards for annotation of PDX characteristics and biology, and progress toward "credentialing" of PDX models as surrogates to represent individual patients for use in preclinical and co-clinical translational research. In addition, this review highlights important unresolved questions, as well as current limitations, that have hampered more efficient generation of PDX lines and more rapid adoption of PDX use in translational breast cancer research

    Bandwagonistas: rhetorical re-description, strategic choice and the politics of counter-insurgency

    No full text
    This paper seeks to explore how a particular narrative focused on populationcentric counterinsurgency shaped American strategy during the Autumn 2009 Presidential review on Afghanistan, examine the narrative’s genealogy and suggest weaknesses and inconsistencies that exist within it. More precisely our ambition is to show how through a process of ‘rhetorical redescription’ this narrative has come to dominate contemporary American strategic discourse. We argue that in order to promote and legitimate their case, a contemporary ‘COIN Lobby’ of influential warrior scholars, academics and commentators utilizes select historical interpretations of counterinsurgency and limits discussion of COIN to what they consider to be failures in implementation. As a result, it has become very difficult for other ways of conceptualizing the counterinsurgency problem to emerge into the policy debate

    Cranial endocast of the Lambeosaurine Hadrosaurid Amurosaurus riabinini from the Amur Region, Russia

    Information on the structure of the brain of the lambeosaurine hadrosaurid dinosaur Amurosaurus riabinini, from the Late Maastrichtian of Blagoveschensk, Far Eastern Russia, is presented based on endocranial casts. The endocasts are compared with physical and digital endocasts of other dinosaurs. The olfactory tract was large. The cerebral hemispheres are enlarged and round, illustrating the important development of this part of the brain in hadrosaurids. The pituitary body is enlarged as well, perhaps prefiguring the large size attained by hadrosaurids. The EQ of Amurosaurus was similar to that of the lambeosaurine dinosaur Hypacrosaurus altispinus and was relatively larger than in most extant non-avian reptiles, including sauropod and ceratopsian dinosaurs. However, it was apparently relatively smaller than those of most theropod dinosaurs. The relatively large size of the cerebrum is consistent with the range and complexity of social behaviors inferred for lambeosaurine dinosaurs.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
