The direct and indirect effects of core and peripheral social capital on organizational performance
Authors: Fonti Fabio , Maoret Massimo 
Published: June 2015

Research summary: In this paper we adopt a core‐periphery approach to specify the direct and indirect effects of social capital on organizational performance. We suggest that social capital deriving from stable task relationships between organizational members has a direct positive effect on organizational performance. Said effect depends, in both strength and functional form, on whether actors involved in stable dyads are located at the core or at the periphery of the organization. We also argue that core and peripheral social capital affect performance indirectly by moderating the organization's ability to leverage its human capital to improve performance. Results from a 48‐year study of the National Basketball Association support our arguments and bear important implications for strategic human resource practices and organizational performance in competitive settings.Managerial summary: Stable work relationships among employees generate trust, more efficient work routines, common understanding and thus higher organizational performance. These benefits depend on the location of such stable relationships in the organization. Relational stability among core organizational members has an immediate, strong impact on performance, an effect that plateaus as stability grows. Stable relationships between core and peripheral members have instead a weaker, yet linear effect on performance. The location of stable relationships is also critical to leverage the talent of core employees, whose contribution to performance is stronger when relational stability is high in the organizational core, yet hindered by stable relations between core and periphery. Such findings provide relevant implications for strategic human resource management, in particular for choices regarding team composition and managing stars. Copyright © 2015 John Wiley & Sons, Ltd.

Published: June 2015

AbstractThe self‐assembly reactions of transition metal ions and 1,3,5‐benzenetricarboxylic acid (H3btc) in the presence of auxiliary aromatic bidentate ligands 1,10‐phenanthroline (1,10‐phen) or 4,4′‐bipyridine‐N,N′‐dioxide (4,4′‐bpdo) have isolated four coordination polymers [Co18(btc)10(H2O)6(OH)6(1,10‐phen)6]·14H2O·3DMF (1) and [M3(btc)2(H2O)4(4,4′‐bpdo)]·2H2O·2DMF [M = Co (2), Mn (3), Ni (4)]. Single‐crystal X‐ray diffraction analysis revealed that the M3 clusters in the structure of 1–4 are connected by hydroxyl group oxygen atoms (or oxygen atoms from 4,4′‐bpdo ligands) and carboxyl groups to generate a three‐dimensional framework. The network of final assemblies can be adjusted by varying the type of auxiliary ligands (1,10‐phen, 4,4′‐bpdo). In addition, the gas adsorption properties of 2 are also investigated.

Abstract
The purpose of this article is to disseminate the standard of antiemetic therapy for Japanese clinical oncologists. On the basis of the Appraisal of Guidelines for Research and Evaluation II instrument, which reflects evidence-based clinical practice guidelines, a working group of the Japanese Society of Clinical Oncology (JSCO) reviewed clinical practice guidelines for antiemesis and performed a systematic review of evidence-based domestic practice guidelines for antiemetic therapy in Japan. In addition, because health-insurance systems in Japan are different from those in other countries, a consensus was reached regarding standard treatments for chemotherapy that induce nausea and vomiting. Current evidence was collected by use of MEDLINE, from materials from meetings of the American Society of Clinical Oncology National Comprehensive Cancer Network, and from European Society of Medical Oncology/Multinational Association of Supportive Care in Cancer guidelines for antiemesis. Initially, 21 clinical questions (CQ) were selected on the basis of CQs from other guidelines. Patients treated with highly emetic agents should receive a serotonin (5-hydroxytryptamine; 5HT3) receptor antagonist, dexamethasone, and a neurokinin 1 receptor antagonist. For patients with moderate emetic risk, 5HT3 receptor antagonists and dexamethasone were recommended, whereas for those receiving chemotherapy with low emetic risk dexamethasone only is recommended. Patients receiving high-emetic-risk radiation therapy should also receive a 5HT3 receptor antagonist. In this paper the 2010 JSCO clinical practice guidelines for antiemesis are presented in English; they reveal high concordance of Japanese medical circumstances with other antiemetic guidelines that are similarly based on evidence.

Published: June 2015

Background Existing hardware may contribute to increased risk of bacterial contamination and subsequent periprosthetic joint infection (PJI) in conversion shoulder arthroplasty performed for failed fracture fixation. Questions/Purposes This study examined the incidence of positive pre-operative aspiration and inflammatory marker data, along with correlation of pre-operative positive aspiration or inflammatory markers and subsequent infection following conversion shoulder arthroplasty for failed open reduction and internal fixation (ORIF) and the need for re-operation at 4.6-year follow-up. Methods Twenty-eight patients who underwent conversion to shoulder arthroplasty for any reason after fracture fixation were retrospectively reviewed in a single center. A pre-operative aspiration was done in 17 patients; all patients had intra-operative tissue sampling. All procedures were single-stage removal of hardware and performance of the arthroplasty. In cases of pre-operative positive bacterial growth, a single-stage procedure was performed according to the septic ENDO-Klinik protocol. Results In 4 of 17 pre-operative joint aspirations, bacterial growth was detected; one pre-operative negative aspiration demonstrated bacterial growth in intra-operative sampling. In three of them, the infection has been validated through intra-operatively results. Pre-operative aspiration showed a sensitivity of 75% and specificity of 92% ( p < 0.005) for infection. No post-operative PJIs were observed. Six revisions were performed, most commonly for aseptic loosening (two cases) and conversion of hemiarthroplasty to a reverse design (two cases). Conclusions In conclusion, the risk of low-grade shoulder infection after fracture osteosynthesis may be higher than in hip and knee joints, based on limited study data. Adequate pre-operative testing is recommended to rule out occult shoulder infection in this setting.
Collision-free tool orientation optimization in five-axis machining of bladed disk
Authors: Chen Li , Xu Ke , Tang Kai 
Published: June 2015

Abstract
Bladed disk (BLISK) is a vital part in jet engines with a complicated shape which is exclusively machined on a five-axis machine and requires high accuracy of machining. Poor quality of tool orientation (e.g., false tool positioning and unsmooth tool orientation transition) during the five-axis machining may cause collision and machine vibration, which will debase the machining quality and in the worst case sabotage the BLISK. This paper presents a reference plane based algorithm to generate a set of smoothly aligned tool orientations along a tool path. The proposed method guarantees that no collision would occur anywhere along the tool path, and the overall smoothness is globally optimized. A preliminary simulation verification of the proposed algorithm is conducted on a BLISK model and the tool orientation generated is found to be stable, smooth, and well-formed.
Lion Optimization Algorithm (LOA): A nature-inspired metaheuristic algorithm
Authors: Yazdani Maziar , Jolai Fariborz 
Published: June 2015

Abstract
During the past decade, solving complex optimization problems with metaheuristic algorithms has received considerable attention among practitioners and researchers. Hence, many metaheuristic algorithms have been developed over the last years. Many of these algorithms are inspired by various phenomena of nature. In this paper, a new population based algorithm, the Lion Optimization Algorithm (LOA), is introduced. Special lifestyle of lions and their cooperation characteristics has been the basic motivation for development of this optimization algorithm. Some benchmark problems are selected from the literature, and the solution of the proposed algorithm has been compared with those of some well-known and newest meta-heuristics for these problems. The obtained results confirm the high performance of the proposed algorithm in comparison to the other algorithms used in this paper.
THE PROBLEM OF THE PROBLEM OF INDUCTION
Authors: White Roger 
Published: June 2015

AbstractTo solve the problem of induction we had first better know what it is. Some ways of formulating the worry about induction are underwhelming as they depend on assumptions that don't survive much scrutiny. Perhaps the most disturbing argument for inductive skepticism appeals to the claim that we could not possibly be justified in taking our inductive methods to be reliable independently of our use of those methods. And the use of inductive methods cannot give us justification to suppose that they are reliable. I argue for a new way to escape the first horn of this dilemma.
Deformation of spherical compound capsules in simple shear flow
Authors: Luo Zheng Yuan , He Long , Bai Bo Feng 
Published: June 2015

The deformation of a compound capsule (an elastic capsule with a smaller capsule inside) in simple shear flow is studied by using three-dimensional numerical simulations based on a front tracking method. The inner and outer capsules are concentric and initially spherical. Skalaket al.’s constitutive law is employed for the mechanics of both the inner and outer membranes. Our results concerning the deformation of homogeneous capsules (i.e. capsules without the inner capsules) are quantitatively in agreement with the predictions of previous numerical simulations and perturbation theories. Compared to homogeneous capsules, compound capsules exhibit smaller deformation. The deformations of both the inner and outer capsules are significantly affected by the capillary numbers of the inner and outer membranes and the volume ratio of the inner to the outer capsule. When the inner capsule is small, it presents smaller deformation than the outer capsule. However, when the inner capsule is sufficiently large, it can present larger deformation than the outer capsule, even if the inner membrane has much lower capillary number than the outer membrane. The underlying mechanisms are discussed: (i) the inner capsule is deformed by rotational flow with lower rate of strain rather than by simple shear flow that deforms the outer capsule, and thus the inner capsule exhibits smaller deformation; and (ii) when the inner and outer membranes are sufficiently close (i.e. the inner capsule is sufficiently large), the hydrodynamic interaction between the two membranes becomes significant, which is found to inhibit the deformation of the outer capsule but to promote the deformation of the inner capsule.

Published: June 2015

It is unclear whether lifestyle modifications, such as dietary changes, should be advocated to prevent olfactory dysfunction. We investigated the association between dietary intakes of fats (saturated, mono-unsaturated and polyunsaturated fats, and cholesterol) and related food groups (nuts, fish, butter, margarine) with olfactory impairment. There were 1331 and 667 participants (older than 60 years) at baseline and 5-year follow-up, respectively, with complete olfaction and dietary data. Dietary data were collected using a validated semi-quantitative FFQ. Olfaction was measured using the San Diego Odor Identification Test. In a cross-sectional analysis of baseline data, those in the highest v. lowest quartile of n-6 PUFA intake had reduced odds of having any olfactory impairment, multivariable-adjusted OR 0·66 (95 % CI 0·44, 0·97), P for trend = 0·06. Participants in the highest v. lowest quartile of margarine consumption had a 65 % reduced odds of having moderate/severe olfactory impairment (P for trend = 0·02). Participants in the highest quartile compared to the lowest quartile (reference) of nut consumption had a 46 % (P for trend = 0·01) and 58 % (P for trend = 0·001) reduced odds of having any or mild olfactory impairment, respectively. Older adults in the highest v. lowest quartile of fish consumption had 35 % (P for trend = 0·03) and 50 % (P for trend = 0·01) reduced likelihood of having any or mild olfactory impairment, respectively. In longitudinal analyses, a marginally significant association was observed between nut consumption and incidence of any olfactory impairment, highest v. lowest quartile of nut consumption: OR 0·61 (95 % CI 0·37, 1·00). Older adults with the highest consumption of nuts and fish had reduced odds of olfactory impairment, independent of potential confounding variables.
RESPONSES OF EUCALYPTUS CAMALDULENSIS SPROUTS TO SHADE: AN EVALUATION OF CANOPY PLASTICITY

Published: June 2015

SUMMARYEucalyptus spp. is the main tree used in cellulose production worldwide, cultivated mostly in extensive monocrop plantations. However, due to concerns on environmental impacts, fear on decrease of food production related to the size of cultivated area, its location near human settlements with few jobs generation, eucalypt cultivation is no longer encouraged in many places. At the same time, large plantations hold the opportunity to integrate eucalypt into agroforestry systems (AFS) in a variety of production systems with many social, economical and environmental advantages. In this study we studied canopy modifications of E. camaldulensis sprouts under different degrees of shade. The plants were located on a gradient of available solar irradiation ranging from 51 to 94%. E. camaldulensis showed canopy plasticity with modified radiation interception patterns under diverse irradiations. Most of these variations were of small amplitude with some important variables remaining almost unchanged (leaf density, canopy percentage, tree, trunk and canopy height) or increasing only slightly (leaf area index and canopy opening). The main changes presented by E. camaldulensis, with a steep increase towards full sun, were: foliage area, canopy surface, canopy volume and area of canopy projection. In order to design appropriate agroforestry systems with young eucalypt growing under the shade of other crops, it is necessary to determine at which point the observed variable changes can support reasonable production.
Précis of Social Perception and Social Reality: Why accuracy dominates bias and self-fulfilling prophecy
Authors: Jussim Lee 
Published: June 2015

AbstractSocial Perception and Social Reality (Jussim 2012) reviews the evidence in social psychology and related fields and reaches three conclusions: (1) Although errors, biases, and self-fulfilling prophecies in person perception are real, reliable, and occasionally quite powerful, on average, they tend to be weak, fragile, and fleeting. (2) Perceptions of individuals and groups tend to be at least moderately, and often highly accurate. (3) Conclusions based on the research on error, bias, and self-fulfilling prophecies routinely greatly overstate their power and pervasiveness, and consistently ignore evidence of accuracy, agreement, and rationality in social perception. The weight of the evidence – including some of the most classic research widely interpreted as testifying to the power of biased and self-fulfilling processes – is that interpersonal expectations relate to social reality primarily because they reflect rather than cause social reality. This is the case not only for teacher expectations, but also for social stereotypes, both as perceptions of groups, and as the bases of expectations regarding individuals. The time is long overdue to replace cherry-picked and unjustified stories emphasizing error, bias, the power of self-fulfilling prophecies, and the inaccuracy of stereotypes, with conclusions that more closely correspond to the full range of empirical findings, which includes multiple failed replications of classic expectancy studies, meta-analyses consistently demonstrating small or at best moderate expectancy effects, and high accuracy in social perception.
EUROSCAN INTERNATIONAL NETWORK MEMBER AGENCIES: THEIR STRUCTURE, PROCESSES, AND OUTPUTS
Authors: Packer Claire , Simpson Sue , de Almeida Rosimary Terezinha 
Published: June 2015

Objectives: The EuroScan International Network is a global network of publicly funded early awareness and alert (EAA) systems for health technologies. We describe the EuroScan member agency systems and methods, and highlight the potential for increased collaboration.Methods: EuroScan members completed postal questionnaires supplemented with telephone interviews in 2012 to elicit additional information and check equivalence of responses. Information was updated between March and May 2013.Results: Fifteen of the seventeen member agencies responded. The principal purpose of agencies is to inform decisions on coverage or reimbursement of health services and decisions on undertaking secondary research. The main users of information are national governments; health professionals; health services purchasers, commissioners, and decision makers; and healthcare providers. Most EuroScan agencies are small with almost half having fewer than two whole time equivalent staff. Ten agencies use both active and passive identification approaches, four use only active approaches. Most start identification in the experimental or investigational stages of the technology life cycle. All agencies assessed technologies when they are between the investigational and established, but under diffusion stages. Barriers to collaboration revolve around different system aims, purposes, and requirements; a lack of staff, finance, or opportunity; language differences; and restrictions on dissemination.Conclusions: Although many barriers to collaboration were identified, the majority of agencies were supportive of increased collaboration either involving the whole EuroScan Network or between individual agencies. Despite differences in the detailed identification processes, members thought that this was the most feasible phase to develop additional collaboration.
High proficiency across two languages is related to better mental state reasoning for bilingual children
Authors: GORDON KATHERINE R. 
Published: June 2015

ABSTRACTPast research suggests that bilingualism positively affects children's performance in false belief tasks. However, researchers have yet to fully explore factors that are related to better performance in these tasks within bilingual groups. The current study includes an assessment of proficiency in both languages (which was lacking in past work) and investigates the relationship between proficiency and performance in a variety of mental state tasks (not just false belief). Furthermore, it explores whether the relationship between language proficiency and performance in mental state tasks differs between bilingual and monolingual groups. Twenty-six Spanish–English bilingual and twenty-six English monolingual preschool-age children completed seven mental state tasks. Findings provide evidence that high proficiency in English is related to better performance in mental state tasks for monolinguals. In contrast, high proficiency in both English and Spanish is related to better performance in mental state tasks for bilinguals.
Transport, driving and ageing
Authors: O’Neill Desmond 
Published: June 2015

SummaryTransport is the invisible glue that holds our lives together, an under-recognized contributor to economic, social and personal well-being. In public health terms, the medical profession had previously allowed itself to focus almost exclusively on the downsides of transport. However, the research basis for transport, driving and ageing is steadily evolving and has important academic and practical considerations for gerontologists and geriatricians. For gerontologists, teasing out the critical role of transport in the health and well-being of older people is an imperative, as well as the key challenges inherent in transitioning from driving to not driving. The safe crash record of a group with significant multi-morbidity allows us to focus on the remarkable strategic and adaptive skills of older people. From a policy perspective, strictures on older drivers are an exemplar of institutionalized ageism. For geriatricians, a key challenge is to develop strategies for including transportation in our clinical assessments, formulating effective strategies for assessment of medical fitness to drive, incorporating enabling techniques, giving due consideration to ethical and legal aspects, and developing and promoting multi-modality and alternative transportation options.

AbstractThe pressure–temperature phase diagram of ice displays a perplexing variety of structurally distinct phases. In the century-long history of scientific research on ice, the proton-ordered ice phases numbered XIII through XV were discovered only recently. Despite considerable effort, none of the transitions leading from the low-temperature ordered ices VIII, IX, XI, XIII, XIV and XV to their high-temperature disordered counterparts were experimentally found to display the full Pauling entropy. Here we report calorimetric measurements on suitably high-pressure-treated, hydrogen chloride-doped ice XIV that demonstrate at the maximum 60% of the Pauling entropy is released at the transition to ice XII. Dielectric spectroscopy on undoped and on variously doped ice XII crystals reveals that addition of hydrogen chloride, the agent triggering complete proton order in ice XIV, enhances the precursor dynamics strongest. These discoveries provide new insights into the puzzling observation that different dopants trigger the formation of different proton-ordered ice phases.
