From Simulation to Real Deployments in WSN and Back

The paper presents our efforts to validate some high-level aspects of the WSN simulator we have built as well as the operational functionality of our multi-parameter MAC protocol. In order to do so, we resort to real deployments involving TelosB motes. The simulator, named Castalia, boasts the most accurate wireless channel and radio models for WSN found in current literature. These models are capturing some essential experimental findings. This does not guaranty though that the simulator will behave similarly with a real deployment at the high level (i.e., the protocol or application level). We investigate how our multi-parameter MAC protocol behaves in a real deployment so as to take a first step towards validating and possibly tuning Castalia. The investigation starts by determining the connectivity map for the real deployment and then trying to reproduce it in the simulator. We then proceed with the protocol testing and comparing. We report the difficulties faced and our findings from this process.
Bargaining and Price-of-Anarchy in Repeated Inter-Session Network Coding Games

Most of the previous work on network coding has assumed that the users are not selfish and always follow the designed coding schemes. However, recent results have shown that selfish users do not have the incentive to participate in inter-session network coding in a static non-cooperative game setting. As a result, the worst-case network efficiency (i.e., the price-of-anarchy) can be as low as 22%. In this paper, we show that if the same game is played repeatedly, then the price-of-anarchy can be significantly improved to 48%. We propose a grim-trigger strategy that encourages users to cooperate and participate in the inter-session network coding. A key challenge is to determine a common cooperative coding rate that the users should mutually agree on. We propose to resolve the conflict of interest among the users through a bargaining process. We derive a tight upper bound for the price-of-anarchy which is valid for any bargaining scheme. Moreover, we propose a simple and efficient min-max bargaining solution that can achieve this upper bound. Our results represent one of the first steps towards designing practical inter-session network coding schemes that can achieve reasonable performance for selfish users.
Kidney Tissue Targeted Metabolic Profiling of Unilateral Ureteral Obstruction Rats by NMR

Renal interstitial fibrosis is a common pathological process in the progression of kidney disease. A nuclear magnetic resonance (NMR) based metabolomic approach was used to analyze the kidney tissues of rats with renal interstitial fibrosis (RIF), induced by unilateral ureteral obstruction (UUO). The combination of a variety of statistical methods were used to screen out 14 significantly changed potential metabolites, which are related with multiple biochemical processes including amino acid metabolism, adenine metabolism, energy metabolism, osmolyte change and induced oxidative stress. The exploration of the contralateral kidneys enhanced the understanding of the disease, which was also supported by serum biochemistry and kidney histopathology results. In addition, the pathological parameters (clinical chemistry, histological and immunohistochemistry results) were correlated with the significantly changed differential metabolites related with RIF. This study showed that targeted tissue metabolomic analysis can be used as a useful tool to understand the mechanism of the disease and provide a novel insight in the pathogenesis of RIF.
DUAL-BAND RADAR INTERFEROMETRY

This paper demonstrates the feasibility of using differential interferometric synthetic aperture radar (DInSAR) for subsidence monitoring over the underground mining sites in New South Wales, Australia. The SAR data acquired in dual-frequency, Cand L-band, of microwave portion of electromagnetic spectrum by ERS-1/2, Radarsat-1 and JERS-1 satellites have been examined. The issues of decorrelation and high phase gradient in the interferometric phase have been addressed. The results of ERS-1/2 tandem interferometry show high conservation of coherence for the two acquisitions with 1 day interval. In contrast, repeat-pass interferometry results with the temporal baselines at the multiples of 24, 35, and 44 days for Radarsat-1, ERS-1/2, and JERS-1, respectively, show the degradation significantly greater than the tandem case due to the much larger temporal baselines. However, Radarsat-1 fine beam mode data show the decorrelation can be reduced using finer imaging resolution. In order to overcome the high phase gradient, either shorter revisit period of the satellite or longer wavelength of the microwave need to be used. The possibility of determining the displacement vectors in 3D is also discussed in this paper.

Chemical composition of 90 F and G disk dwarfs

High resolution, high S/N spectra have been obtained for a sample of 90 F and G main-sequence disk stars covering the metallicity range 1:0 < (Fe/H) < +0:1, and have been analysed in a parallel way to the work of Edvardsson et al. (1993a) in order to re-inspect their re- sults and to reveal new information on the chemical evo- lution of the Galactic disk. Compared to Edvardsson et al. the present study in- cludes several improvements. Eective temperatures are based on the Alonso et al. (1996) calibration of color in- dices by the infrared flux method and surface gravities are calculated from Hipparcos parallaxes, which also allow more accurate ages to be calculated from a comparison of MV and Te with isochrones. In addition, more reli- able kinematical parameters are derived from Hipparcos distances and proper motions in combination with accu- rate radial velocities. Finally, a larger spectral coverage, 5600 8800 A, makes it possible to improve the abundance accuracy by studying more lines and to discuss several el- ements not included in the work of Edvardsson et al. The present paper provides the data and discusses some general results of the abundance survey. A group of stars in the metallicity range of 1:0 < (Fe/H) < 0:6 having a small mean Galactocentric distance in the stellar orbits, Rm < 7 kpc, are shown to be older than the other disk stars and probably belong to the thick disk. Excluding these stars, a slight decreasing trend of (Fe/H) with increasing Rm and age is found, but a large scatter in (Fe/H) (up to 0.5 dex) is present at a given age andRm. Abundance ratios with respect to Fe show, on the other hand, no signicant scatter at a given (Fe/H). The derived
A retrospective seven-year analysis of the use of B cell depletion therapy in systemic lupus erythematosus at University College London Hospital: the first fifty patients.

OBJECTIVE To describe the 6-month clinical outcome and the long-term safety profile of B cell depletion therapy (BCDT) in 50 patients with active systemic lupus erythematosus (SLE), who were nonresponsive or poorly responsive to conventional immunosuppression. METHODS All except 4 of 50 patients with active SLE received 1 gm of rituximab, 750 mg of cyclophosphamide, and 100-250 mg of methylprednisolone, administered on 2 occasions 2 weeks apart, to achieve B cell depletion. Clinical outcome was assessed using the British Isles Lupus Assessment Group (BILAG) activity index and serial serologic measurements of disease activity. Remission was defined as a change from a BILAG A or B score to a C or D score in every organ system. Partial remission was a change from a BILAG A or B score to a C or D score in at least 1 system, but with the persistence of 1 score of A or B in another system. No improvement was defined as a BILAG A or B score that remained unchanged after treatment. RESULTS Of the 45 patients available for followup at 6 months, 19 patients (42%) achieved remission, and 21 patients (47%) reached partial remission after 1 cycle of BCDT (mean followup 39.6 months). BCDT resulted in a decrease in median global BILAG scores from 12 to 5 (P < 0.0001) and median anti-double-stranded DNA antibody titers from 106 to 42 IU/ml (P < 0.0001), and an increase in the median C3 level from 0.81 to 0.95 mg/liter (P < 0.02) at 6 months. Five serious adverse events were observed. CONCLUSION BCDT is an effective treatment for patients with active SLE whose disease has failed to respond to standard immunosuppressive therapy. Although the safety profile of BCDT is favorable, ongoing monitoring is required.
Self–Serving or Self–Actualizing? Models of Man and Agency Costs in Different Types of Family Firms: A Commentary on “Comparing the Agency Costs of Family and Non–family Firms: Conceptual Issues and Exploratory Evidence”

Provides a reaction tothearticle"Comparing the agency costs of family and non-family firms:Conceptual issues and exploratory evidence," by Chrisman, Chua, and Litz inthe same issue of Entrepreneurship Theory and Practice. This commentaryexamines theeffects of agency relationships on family firms presented byChrisman et al, andsuggests the alternative influence of stewardshiptheory, which complements the agency framework in explaining entrepreneurial,organizationally-centered behaviors. The main thrust is to suggest that differences in organizational performanceare not driven by family involvement or its lack, but more by the existence ofagency or stewardship relationships within firms, regardless of the degree ofactual family involvement. Conclusions indicate that Chrisman et al.'s findingsmay be flawed because their study did not provide any significant performancedifferences between family and non-family firms. The differences may also varyby the types of businesses in which family firms are engaged. It is suggestedthat the issues of agency and stewardship relationships should be studied morecarefully and should avoid oversimple dichotomies such as family and non-familyfirms. (JSD)
KINEMATIC PROPERTIES AND STELLAR POPULATIONS OF FAINT EARLY-TYPE GALAXIES. II. LINE-STRENGTH MEASUREMENTS OF CENTRAL COMA GALAXIES

We present line-strength measurements for 74 early-type galaxies in the core of the Coma cluster reaching down to velocity dispersions, σ, of 30 km s−1. The index-σ relations for our sample, including galaxies with σ < 100 km s−1 (low-σ), differ in shape depending on which index is used. We note two types of relations for the metallic indices: one showing a break in the slope around ∼100 km s−1 and another group with strong linear relations between an index and log σ. We find no connection between the behavior of index–σ relations with either α- or Fe-peak elements. However, we find indications that the relations are tighter for indices which do not depend on the microturbulent velocities of stellar atmospheres. We confirm previous results that low-σ galaxies including dE/dS0s are on average younger, less metal rich, and have lower [α/Fe] in comparison with E/S0s. Our data show that these trends derived for high-σ galaxies extend down to dE/dS0s. This is a factor of ∼2 lower in σ than previously published work. We confirm that the observed anticorrelation between age and metallicity for high-σ galaxies is consistent with the effects of correlated errors. Low-σ galaxies also show a similar relation between age and metallicity as a result of correlated errors. However, they are offset from this relationship so that, on average, they are less metal rich and younger than their high-σ counterparts.
Tattoos, Modernisation, and the Nation-State: Dai Lue Bodies as Parchments for Symbolic Narratives of the Self and Chinese Society*

In this article, we report our research on Dai Lue in a rural area of Xishuangbanna, revealing how their tattoos have become an emblem of the self or an interiority cultivated through outer appearance, acted out and contested on people’s bodies as parchments for society’s discourses. China’s version of modernisation and nation-state building has underpinned shifting tattoo designs and subjectivities. Tattooing among younger people was different to their elders, as they were less inclined to practise it for a sense of belonging and conformity to Dai Lue and, instead, did so to stand out from and within their ethnic group, expressing a more individual and volitional self—a profound cultural change which also pervades many other aspects of their lives. We also show how popular discourses in China concerning the nation and ethnic minorities are being embodied and visually performed by Dai Lue through their tattoos, albeit creatively and not homogeneously. Our findings call for a more inclusive national story line in China which moves beyond simple stereotypes of ethnic categories currently popular in society to appreciate the complexity of peoples’ lives. Our study also updates the literature on tattooing among Dai Lue which, hitherto, was limited to descriptions in Chinese texts of old tattoo designs and rituals in isolation from society and politics.

When Do People Initiate a Negotiation? The Role of Discrepancy, Satisfaction, and Ability Beliefs

Negotiation research increasingly pays attention to the beginning of negotiations. Building on a theory of the initiation of negotiation we investigated when and why people consider initiating negotiations. Results from one field study and two scenario experiments show that a negative discrepancy between an actual state and a desired state increased the intention to initiate a negotiation and promoted real initiation behavior. This effect was mediated by the subjective perception of this discrepancy and feelings of dissatisfaction. Expectancy considerations in the form of ability to initiate negotiations and implicit beliefs about negotiation ability moderated this serial mediation effect: high initiation ability and incremental negotiation beliefs facilitated the decision to negotiate whereas low initiation ability and entity negotiation beliefs inhibited negotiation initiations. In the present work, we offer a first empirical test of the theory of initiation of negotiation.
Implementation of evidence-based medicine: evaluation of the Promoting Action on Clinical Effectiveness programme

Objectives: To evaluate the Promoting Action on Clinical Effectiveness (PACE) programme, which sought to implement clinically effective practice in 16 local sites. Methods: 182 semi-structured interviews, usually by telephone, with project team members, clinicians, and senior managers and representatives from the Department of Health and the King's Fund. Results: The most influential factors were strong evidence, supportive opinion leaders and integration within a committed organization; without these factors, projects had little chance of success. Other factors (context analysis, professional involvement and good project management) emerged as important, supporting processes; their presence might be an additional help, but on their own they would not be enough to initiate change. A serious problem with any of them could have a strong adverse impact. Conclusions: Although there is no simple formula for the factors that ensure successful implementation of research-based improvements to clinical practice, certain principles do seem to help. Time and resource need to be devoted to a period of local negotiation and adaptation of good research evidence based on a careful understanding of the local context, in which opinion leader influence is an important component of a well managed and preferably well integrated process of change.
Framing and Blame Attribution in Populist Rhetoric

The rhetoric of populist politicians is an important part of their appeal; however, little is known about how that rhetoric operates. Drawing on two large experiments conducted with American adults, we show that frames encouraging individuals to consider political problems in dispositional terms prompt populist expressions, while an encouragement to consider these same problems situationally does not. In our second experiment, we connect this framing change to voting intentions and find that subjects exposed to dispositional frames are more likely to express support for Donald Trump and less likely to express support for Hillary Clinton than subjects exposed to situational frames. We find the same pattern when we compare Bernie Sanders with Clinton but not when we compare Trump with Sanders. Importantly, the impact is contingent on preexisting populist attitudes; subjects with lower populist attitudes are more likely to demonstrate an increase in expressed populism and support for populist candidates.
Assigning Educational Videos at Appropriate Locations in Textbooks

The emergence of tablet devices, cloud computing, and abundant online multimedia content presents new opportunities to transform traditional paper-based textbooks into tablet-based electronic textbooks. Towards this goal, techniques have been proposed to automatically augment textbook sections with relevant web content such as online educational videos. However, a highly relevant video can be created at a granularity that may not mimic the organization of the textbook. We focus on the video assignment problem: Given a candidate set of relevant educational videos for augmenting an electronic textbook, how do we assign the videos at appropriate locations in the textbook? We propose a rigorous formulation of the video assignment problem and present an algorithm for assigning each video to the optimum subset of logical units. Our experimental evaluation using a diverse collection of educational videos relevant to multiple chapters in a textbook demonstrates the efficacy of the proposed techniques for inferring the granularity at which a relevant video should be assigned.
Ownership and Corporate Governance: Evidence from the Czech Republic

The Czech Republic's mass-privatization scheme changed the governance of many firms in a short time. The authors show that mass privatization was effective in improving firm management because of the concentrated ownership structure that resulted. For a cross section of 706 firms for the period 1992-95, they find that the more concentrated the firm's ownership, the higher the firm's market valuation and profitability. Large ownership through bank-sponsored investment funds and strategic investors appears to be particularly important in improving corporate governance and turning firms around. They find no evidence that market valuation or profitability were lower for firms in which investment funds sponsored by a firm's main bank represented a large ownership stake. It is often argued that the firm's main bank having (indirect) ownership control could represent a conflict of interest. The empirical analysis here shows, quite the contrary, that such indirect ownership control has a significant positive influence. On balance, banks that had an (indirect) equity stake in a firm have a positive influence on the firm's corporate governance.

A semiparametric stochastic spline model as a managerial tool for potential insolvency

This study introduces a flexible nonlinear semiparametric spline model, new to solvency studies, as a tool for managerial discretion and regulatory oversight. The model has a linear component and a nonlinear component that uses stochastic splines. The study focuses on the functional relationship between regressors and the probability of financial distress as an object for managerial action. Leverage plots are provided to analyze the potential effect of decisions to modify firm levels of financial variables. If the true relationship between regressors and the response is not linear, then managerial efforts to rectify deteriorating financial conditions can be misinformed by reliance on a linear solvency model. The leverage plots adjust to the firm's position within the industry and its specific levels of various financial variables. A five-regressor semiparametric spline model is shown to yield insights into the behavior of the risk of financial distress probabilities that linear parametric models suppress. The model also classifies and validates well in comparison with recent insolvency studies and as well as parametric logit and probit models on the same data.
Cosmological Hydrogen Reionization with Three-dimensional Radiative Transfer

We present new calculations of the inhomogeneous process of cosmological reionization by carefully following the radiative transfer in precomputed hydrodynamic simulations of galaxy formation. These new computations represent an important step on the way toward fully self-consistent and adaptive calculations, which will eventually cover the enormous range of scales from sizes of individual minihalos to the mean free path of ionizing photons in the postoverlap universe. The goal of such simulations is to include enough realistic physics to accurately model the formation of early structures and the end of the "dark ages. " Our new calculations demonstrate that the process by which the ionized regions percolate the universe is complex and that the idea of voids being ionized before overdense regions is too simplistic. It seems that observational information pertaining to the reionization epoch may now be in our grasp, through the detection of Gunn-Peterson troughs at z ~ 6. If so, then the comparison of information from many lines of sight with simulations such as ours may allow us to disentangle details of the ionization history and trace the early formation of structure.
