United They Fall: Why the International Community Should Not Promote Military Integration after Civil War
The single strongest predictor of civil war is a nation having had one in the past, and preventing the recurrence of civil war has thus become the critical problem for both scholarship and policy. The conventional wisdom urges the creation of capable, legitimate, and inclusive postwar states to reduce the risk of relapse into civil war, and international peacebuilders have often encouraged the formation of a new national army including members of the war’s opposing sides. However, military integration has received little theoretical or empirical attention. Filling that gap, we argue that both the theoretical logics and the empirical record identifying military integration as a significant contributor to durable post-civil war peace are weak. Our analysis of eleven cases finds little evidence that military integration played a substantial causal role in preventing the return to civil war and little support for the likely causal mechanisms. Military integration does not usually send a costly signal of the parties’ commitment to peace, provide communal security, employ many possible spoilers, or act as a powerful symbol of a unified nation. We conclude that it is both unwise and unethical for the international community to press military integration on reluctant local forces.Based in part on a larger collective project: Roy Licklider (Ed.).

Computing Roadmaps of Semi-algebraic Sets (Extended Abstract)
) S. Basu R. Pollack y M.-F. Roy z Department of Department of Department of Computer Science, Mathematics, Mathematics, Courant Institute Courant Institute Universit'e de Rennes New York, New York, Campus de Beaulieu NY 10012 NY 10012 35042 Rennes cedex FRANCE Abstract We consider a semi-algebraic set S defined by s polynomials of degree d in k variables. We present a new algorithm for computing a semi-algebraic path in S connecting two points if they happen to lie in the same connected component of S. This algorithm, which works in time s k+1 d O(k 2 ) improves the complexity of the fastest algorithm solving this problem known to this date. 1 Introduction 1.1 The Problem Given a finite family of polynomials, P = fP1 ; . . . ; Psg ae D[X1 ; . . . ; Xk ]; where R is a real closed field and D is the smallest subring of R containing the coefficients of the polynomials in P, and a semi- algebraic set S; defined by a Boolean formula with atoms of the form P i oe0; oe 2 f!;?..
Identifying Predictors of Interferon-gamma Release Assay Results in Pediatric Latent Tuberculosis: a Protective Role of BCG?
The transcription factor Sox2 is required for osteoblast self-renewal.
The development and maintenance of most tissues and organs require the presence of multipotent and unipotent stem cells that have the ability of self-renewal as well as of generating committed, further differentiated cell types. The transcription factor Sox2 is essential for embryonic development and maintains pluripotency and self-renewal in embryonic stem cells. It is expressed in immature osteoblasts/osteoprogenitors in vitro and in vivo and is induced by fibroblast growth factor signaling, which stimulates osteoblast proliferation and inhibits differentiation. Sox2 overexpression can by itself inhibit osteoblast differentiation. To elucidate its function in the osteoblastic lineage, we generated mice with an osteoblast-specific, Cre-mediated knockout of Sox2. These mice are small and osteopenic, and mosaic for Sox2 inactivation. However, culturing calvarial osteoblasts from the mutant mice for 2-3 passages failed to yield any Sox2-null cells. Inactivation of the Sox2 gene by Cre-mediated excision in cultured osteoblasts showed that Sox2-null cells could not survive repeated passage in culture, could not form colonies, and arrested their growth with a senescent phenotype. In addition, expression of Sox2-specific shRNAs in independent osteoblastic cell lines suppressed their proliferative ability. Osteoblasts capable of forming 'osteospheres' are greatly enriched in Sox2 expression. These data identify a novel function for Sox2 in the maintenance of self-renewal in the osteoblastic lineage

Impedance studies on PF6- doped Poly(3,4 ethylenedioxythiophene) Devices
Carrier density, substrate and synthesis temperature dependent impedance measurements have been performed on Poly(3,4-ethylenedioxythiophene) PEDOT] based devices in metal/polymer/metal geometry at room temperature. The relaxation mechanism of carries in these devices can be varied as per the growth condition. It is observed that in stainless steel (SS)/PEDOT/Silver (Ag) devices, as the carrier density decreases the interface related mechanism takes control over bulk transport, but as the synthesis temperature is lowered the bulk transport dominates over interface related mechanism. The substrate dependent studies have shown that the electrode potential can alter the growth of polymer chains, which affects the relaxation mechanism of the carriers
