THE ROLE OF INTERDEPENDENCE IN THE MICRO-FOUNDATIONS OF ORGANIZATION DESIGN: TASK, GOAL, AND KNOWLEDGE INTERDEPENDENCE

Interdependence is a core concept in organization design, yet one that has remained consistently understudied. Current notions of interdependence remain rooted in seminal works, produced at a time when managers’ near-perfect understanding of the task at hand drove the organization design process. In this context, task interdependence was rightly assumed to be exogenously determined by characteristics of the work and the technology. We no longer live in that world, yet our view of interdependence has remained exceedingly task-centric and our treatment of interdependence overly deterministic. As organizations face increasingly unpredictable workstreams and workers co-design the organization alongside managers, our field requires a more comprehensive toolbox that incorporates aspects of agent-based interdependence. In this paper, we synthesize research in organization design, organizational behavior, and other related literatures to examine three types of interdependence that characterize organizations’ workflows: task, goal, and knowledge interdependence. We offer clear definitions for each construct, analyze how each arises endogenously in the design process, explore their interrelations, and pose questions to guide future research

MFSD2A Promotes Endothelial Generation of Inflammation-resolving Lipid Mediators and Reduces Colitis in Mice

Alterations in signaling pathways that regulate resolution of inflammation (resolving pathways) contribute to pathogenesis of ulcerative colitis (UC). The resolution process is regulated by lipid mediators, such as those derived from the \u3c9-3 docosahexaenoic acid (DHA), whose esterified form is transported by the major facilitator superfamily domain containing 2A (MFSD2A) through the endothelium of brain, retina, and placenta. We investigated if and how MFSD2A regulates lipid metabolism of gut endothelial cells to promote resolution of intestinal inflammation

Public Governance and Productive Efficiency in Sub-Saharan Africa

3siDo economic variables operate through the channel of public governance to impact technical (or productive) efficiency in Sub Saharan Africa? We present different stochastic frontier models where technical efficiency is a relation between three economic variables, education, government spending, and trade openness, and three public governance variables, government effectiveness, political stability, and regulatory quality. In all cases, education operates through public governance to improve efficiency while government spending does not.JEL classification codes: D02, E02, H11, O47, O55noneDo economic variables operate through the channel of public governance to impact technical (or productive) efficiency in Sub Saharan Africa?

L’induzione della maturazione cervicale con Cervical Ripening Balloon: la nostra esperienza

Obiettivi. Il nostro studio si è proposto di valutare l’effettivo cambiamento, in senso di maturazione, della cervice uterina dopo l’applicazione del Cervical Ripening Balloon (CRB), di valutare il tempo che è intercorso tra la rimozione del dispositivo e l’espletamento del parto e la modalità stessa del parto. Materiali e metodi. Nel nostro studio sono stati raccolti i dati relativi a 7 punti nascita, distribuiti sul territorio nazionale, ed è stata confrontata la casistica dell’ospedale di Pistoia con la casistica degli altri punti nascita. Sono state arruolate 168 pazienti, rispettivamente 46 ricoverate presso l’Ospedale di Pistoia e 122 ricoverate negli altri punti nascita, con feto singolo in presentazione di vertice. Il parametro utilizzato da entrambi i gruppi di studio per valutare il grado di maturazione cervicale è stato lo score di Bishop. Soltanto due punti nascita, oltre allo score di Bishop, hanno utilizzato anche la cervicometria ecografica per valutare la lunghezza del canale cervicale. Conclusioni. I nostri risultati, in accordo con la letteratura internazionale, suggeriscono che il Cervical Ripening Balloon, oltre ad essere facile da applicare e di norma ben tollerato dalle pazienti, non è gravato da effetti collaterali negativi che compromettano l’outcome materno-fetale. Il dispositivo induce modificazioni nello score di Bishop è potrebbe quindi essere utilizzato per la maturazione del collo uterino propedeutica all’induzione, poiché una cervice già preparata e conseguentemente maturata facilita la successiva induzione del parto e ne abbrevia i tempi. Il CRB è una razionale ed efficace alternativa alle prostaglandine qualora queste fossero controindicate o non avessero ottenuto l’effetto desiderato nell’ambito dell’induzione

GPR120 prevents colorectal adenocarcinoma progression by sustaining the mucosal barrier integrity

GPR120 (encoded by FFAR4 gene) is a receptor for long chain fatty acids, activated by omega-3 Polyunsaturated Fatty Acids (PUFAs), and expressed in many cell types. Its role in the context of colorectal cancer (CRC) is still puzzling with many controversial evidences. Here, we explored the involvement of epithelial GPR120 in the CRC development. Both in vitro and in vivo experiments were conducted to mimic the conditional deletion of the receptor from gut epithelium. Intestinal permeability and integrity of mucus layer were assessed by using Evans blue dye and immunofluorescence for MUC-2 protein, respectively. Microbiota composition, presence of lipid mediators and short chain fatty acids were analyzed in the stools of conditional GPR120 and wild type (WT) mice. Incidence and grade of tumors were evaluated in all groups of mice before and after colitis-associated cancer. Finally, GPR120 expression was analyzed in 9 human normal tissues, 9 adenomas, and 17 primary adenocarcinomas. Our work for the first time highlights the role of the receptor in the progression of colorectal cancer. We observed that the loss of epithelial GPR120 in the gut results into increased intestinal permeability, microbiota translocation and dysbiosis, which turns into hyperproliferation of epithelial cells, likely through the activation of beta -catenin signaling. Therefore, the loss of GPR120 represents an early event of CRC, but avoid its progression as invasive cancer. these results demonstrate that the epithelial GPR120 receptor is essential to maintain the mucosal barrier integrity and to prevent CRC developing. Therefore, our data pave the way to GPR120 as an useful marker for the phenotypic characterization of CRC lesions and as new potential target for CRC prevention.Proteomic

A multicentric trial (Olympia-MITO 13) on the accuracy of laparoscopy to assess peritoneal spread in ovarian cancer

OBJECTIVE: The objective of the study was to prospectively evaluate the accuracy of laparoscopy performed in satellite centers (SCs) to describe intraabdominal diffusion of advanced ovarian cancer (AOC). STUDY DESIGN: Patients with a clinical/radiological suspicion of AOC were included in the protocol. SCs were selected among those surgeons, spending a short intensive training period at the coordinator center (CC) to learn the application of staging laparoscopy (S-LPS) in AOC. All women underwent S-LPS at the SCs, and the surgical procedure was recorded and blindly reviewed at the CC. Calculating specificity, positive and negative predictive values, and the accuracy for each parameter with respect to the CC assessed the diagnostic performance of S-LPS. The Cohen's kappa was used to test the interobserver agreement of each parameter. RESULTS: One hundred sixty-eight cases were considered eligible for the study. A per-protocol analysis was performed on 120 cases. The worst laparoscopic assessable feature was mesenteric retraction, whereas the remaining variables ranged from 99.2% (peritoneal carcinomatosis) to 90% (bowel infiltration). All but 1 SC (SC number 4) reached an accuracy rate of 80% or greater for both single parameters and overall score. The Cohen's kappa and the P value for overall predicitive index value were 0.685 and .01, respectively, but improved to 0.773 and .388 after removing the SC number 4 from the analysis. CONCLUSION: S-LPS allows an accurate and reliable assessment of intraperitoneal diffusion of disease in AOC patients in trained gynecological oncology centers
