Cautious Defection: Group Representatives Cooperate and Risk Less than Individuals
Authors: Atanasov Pavel , Kunreuther Howard 
Published: May 2015

AbstractIndividuals often make decisions that affect groups, yet the propensities of group representatives are not as well understood than those of independent decision makers or deliberating groups. We ask how responsibility for group payoffs—in the absence of group deliberation—affects the choice. The experiment utilizes the Interdependent Security Dilemma paradigm. In its deterministic version, the game is identical to a finitely repeated Prisoner's Dilemma. In the stochastic version, potential losses are larger but uncertain, occurring with a predefined probability when one or both players choose to forgo investment in protection. Participants were assigned to play either as individuals, or as representatives of three‐person groups, with each member's choices equally likely to determine the group's payoffs. In the deterministic condition, individuals were more likely to invest (cooperate) than group representatives (80% vs. 62% of rounds). In the stochastic condition, the pattern was reversed as representatives were slightly, but not significantly, more likely to invest than individuals (46% vs. 40%). The significant interaction effect suggested that group representatives were not only less cooperative but also more risk averse than individuals. A follow‐up study supported this account by showing participants who construed the invest strategy as low‐risk than those who perceived this strategy to be high risk. Overall, group representatives exhibited a tendency to act more competitively and more cautiously than individuals acting alone. Copyright © 2015 John Wiley & Sons, Ltd.

AbstractDendritic cells (DCs) are the most potent antigen‐presenting cells that play a crucial role in the initiation of an immune response. As DC‐based therapeutic applications is increasing, large‐scale DC production is required for transplantation. Human umbilical cord blood (UCB) has been shown to contain a rare and precious population of hematopoietic stem cells (HSCs), which can give rise to DCs. The CD34 antigen has been widely used as a cell surface marker to identify HSCs. In this study, we used CD34 antibody to isolate CD34+ and CD34− cells and compared the ability to differentiate into DCs. We used a two‐step method combined with the magnetic bead sorting system to isolate CD34+ and CD34− cells from human UCB. Analysis of cellular properties and functionality using a migration assay and T cell proliferation assay revealed no significant differences between CD34+ cells and CD34− cells in their ability to generate DCs.
Management for traumatic chronic subdural hematoma patients with well‐controlled shunt system for hydrocephalus
Authors: Yamada Shoko Mitrrt , Tomia Yusuke , Murakami Hideki , Nakane Makoto 
Published: May 2015

Key Clinical MessageTraumatic CSDH enlarged in two cases with VP or LP shunt system although the shunt valve pressure was increased to 200 mmH2O. In surgery, the hematoma cavity pressure was found to be 130 and 140 mmH2O, suggesting that to raise the shunt valve pressure is not effective for decreasing CSDH volume.
Tracking Non‐Uniform Mesoscale Transport in LiFePO4 Agglomerates During Electrochemical Cycling

Published: May 2015

AbstractState‐of‐charge maps of a LiFePO4 electrode in standard nonaqueous electrolyte are recorded in operando with a resolution of tens of nanometers by using hard X‐ray spectroscopic microscopy. We observe spatially inhomogeneous charging and discharging of the composite electrode, with predominately Li‐rich and Li‐poor micron‐scale agglomerates. There appears to be no correlation between the agglomerate size and the (de)lithiation pathway. Additionally, we observe that the electrochemical heterogeneity exhibits a “last to delithiate, first to lithiate” behavior, in which the regions that are the last to charge are also the regions that are the first to discharge. These observations suggest that the nanoscale pore structure within the agglomerates dominates lithium‐ion transport.
On the Extreme Oxidation States of Iridium
Authors: Pyykkö Pekka , Xu Wen‐Hua 
Published: May 2015

AbstractIt has recently been suggested that the oxidation states of Ir run from the putative −III in the synthesized solid Na3[Ir(CO)3] to the well‐documented +IX in the species IrO4+. Furthermore, [Ir(CO)3]3−was identified as an 18‐electron species. A closer DFT study now finds support for this picture: The orbitals spanned by the 6s,6p,5d orbitals of the iridium are all occupied. Although some have considerable ligand character, the deviations from 18 e leave the orbital symmetries unchanged. The isoelectronic systems from Os−IVto Au−Ibehave similarly, suggesting further possible species. To paraphrase Richard P. Feynmann “there is plenty of room at the bottom”.
Experimental and Theoretical Investigations of the Stereoselective Synthesis of P‐Stereogenic Phosphine Oxides
Authors: Copey Laurent , Jean‐Gérard Ludivine , Framery Eric , Pilet Guillaume , Robert Vincent , Andrioletti Bruno 
Published: May 2015

AbstractAn efficient enantioselective strategy for the synthesis of variously substituted phosphine oxides has been developed, incorporating the use of (1S,2S)‐2‐aminocyclohexanol as the chiral auxiliary. The method relies on three key steps: 1) Highly diastereoselective formation of PV oxazaphospholidine, rationalized by a theoretical study; 2) highly diastereoselective ring‐opening of the oxazaphospholidine oxide with organometallic reagents that takes place with inversion of configuration at the P atom; 3) enantioselective synthesis of phosphine oxides by cleavage of the remaining PO bond. Interestingly, the use of a PIII phosphine precursor afforded a P‐epimer oxazaphospholidine. Hence, the two enantiomeric phosphine oxides can be synthesized starting from either a PV or a PIII phosphine precursor, which constitutes a clear advantage for the stereoselective synthesis of sterically hindered phosphine oxides.

Outsourcing Canadian Armed Forces logistics in a foreign theatre
Authors: Tchokogué André , Nollet Jean , Fortin Julie 
Published: May 2015

AbstractSuccessful outsourcing of military logistics depends much on cooperation and efficiency, and this article provides an in‐depth analysis of challenges this may pose using collaborative competence theory. Using an exploratory approach, this paper is based on a review of the existing literature and on the experience of the Canadian Armed Forces in a foreign theatre. Specifically, the information collected comes from on‐site observation during the UN mission in Bosnia, semistructured interviews, and archives. Our analysis shows that outsourcing military logistics activities in a foreign theatre should be seen as building and managing a “temporary network.” In order to overcome challenges in such a situation, the Armed Forces must specifically act on the adaptability of all individuals in the theatre. The approach should be based on “collaborative competence.” Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.
Prefrontal cortex afferents to the anterior temporal lobe in the Macaca fascicularis monkey

ABSTRACTThe anatomical organization of the lateral prefrontal cortex (LPFC) afferents to the anterior part of the temporal lobe (ATL) remains to be clarified. The LPFC has two subdivisions, dorsal (dLPFC) and ventral (vLPFC), which have been linked to cognitive processes. The ATL includes several different cortical areas, namely, the temporal polar cortex and rostral parts of the perirhinal, inferotemporal, and anterior tip of the superior temporal gyrus cortices. Multiple sensory modalities converge in the ATL. All of them (except the rostral inferotemporal and superior temporal gyrus cortices) are components of the medial temporal lobe, which is critical for long‐term memory processing. We studied the LPFC connections with the ATL by placing retrograde tracer injections into the ATL: the temporal polar (n = 3), perirhinal (areas 35 and 36, n = 6), and inferotemporal cortices (area TE, n = 5), plus one additional deposit in the posterior parahippocampal cortex (area TF, n = 1). Anterograde tracer deposits into the dLPFC (A9 and A46, n = 2), the vLPFC (A46v, n = 2), and the orbitofrontal cortex (OF; n = 2) were placed for confirmation of those projections. The results showed that the vLPFC displays a moderate projection to rostral area TE and the dorsomedial portion of the temporal polar cortex; in contrast, the dLPFC connections with the ATL were weak. By comparison, the OFC and medial frontal cortices (MFC) showed dense connectivity with the ATL, namely, A13 with the temporopolar and perirhinal cortices. All areas of the MFC projected to the temporopolar cortex, albeit with a lower intensity. The functional significance of such paucity of LPFC afferents is unknown. J. Comp.
