Seeing the Big Picture: A Within-Person Examination of Leader Construal Level and Vision Communication

Despite the importance of leader vision communication to effective leadership, little is known about what prompts leaders to communicate a vision in the first place. Drawing from construal level theory, we examined the within-person relationship of leader construal level in the morning with vision communication during that workday. Leadership self-identity, or the extent to which “being a leader” is central to one’s self-concept, was specified as a cross-level moderator of the daily construal level–vision communication relationship. We tested our predictions using an experience sampling design across 15 consecutive workdays. In total, we obtained a total of 394 matched morning and afternoon surveys from 44 mid- to high-level managers. Results revealed that a high-level construal level in the morning was positively associated with vision communication during the day but only when leadership self-identity is high (vs. low). We discuss the theoretical implications of our findings, in particular with regard to the emerging field of visionary leadership as well as the emerging literature that uses construal level theory to explain leadership phenomena.
Cooperative navigation using environment compliant robot formations

This paper reports an autonomous cooperative navigation system for robot formations in realistic scenarios. The formation movement control is based on a virtual structure composed by spring-dampers elements, which allows the formation to comply with the environment shape. A different navigation strategy is applied to the leader of the formation and to the rest of robots of the team. The leader plans the trajectories by using a two-level path planner with obstacle avoidance capabilities. The motion of the follower robots is controlled by the virtual structure, which adapts to the environment while the leader is tracked, taking into account the kinodynamic constraints of the vehicles. The system is evaluated in experiments carried out in simulations, some of them made in a realistic and complex urban scenario, and with real robots.
Refractory Ascites with Liver Fibrosis Developed in Late Phase Allogeneic Hematopoietic Stem Cell Transplantation: Report of Three Patients

We report cases of three patients of refractory ascites without other fluid retention that occurred around five months after allogeneic hematopoietic stem cell transplantation (allo-HSCT). All three patients expired and postmortem examinations revealed unexpected liver fibrosis lacking histological evidences of graft-versus-host-disease (GVHD). The three patients showed normal hepatic function and size before transplantation. During their clinical courses, serum biochemistry test showed no elevation of hepatic enzymes and bilirubin; however, imaging studies demonstrated hepatic atrophy at the onset of ascites. One of the liver specimens showed bile obstruction, which could be seen in hepatic damage by GVHD. Although ascites resulting from venoocclusive disease in early phase allo-HSCT is well documented, ascites associated with hepatic fibrosis in late phase allo-HCST has not been reported. Further clinico-pathological studies on similar patients should be required to ascertain refractory ascites associated with liver fibrosis after allo-HSCT.
Use of mental simulations to change theory of planned behaviour variables.

OBJECTIVES The predictive validity of the theory of planned behaviour is well established, but much less is known about: (a) whether there are causal relationships between key components of the model and (b) how to go about changing the theory of planned behaviour variables. This study tested the ability of outcome and process simulations to change variables specified in the theory of planned behaviour in relation to blood donation. DESIGN Participants (N=146) were randomized to one of four conditions: outcome simulation only, process simulation only, process-plus-outcome simulation and a distractor control condition. The dependent variables were state anxiety, and intention attitude, subjective norm and perceived control from the theory of planned behaviour. METHODS Participants were asked to empty their mind and visualize themselves: (a) after donating blood (outcome manipulation), (b) preparing to donate blood (process manipulation), (c) both preparing to donate blood and after having donated blood (process-plus-outcome manipulation) or (d) both preparing to get a high mark and after having got a high mark on their course (control condition). Following mental rehearsal, participants completed the dependent variables. RESULTS There were no main effects of outcome simulation, but process simulation successfully increased intention, subjective norm and perceived control. There was also a significant outcome simulation x process simulation interaction for attitude. The effect of the process manipulation on intention was mediated by subjective norm and perceived control. CONCLUSIONS The findings show promise for the use of mental simulations in changing cognitions and further research is required to extend the present findings to other health behaviours.
Testable Implications of Affine Term Structure Models

Affine term structure models have been used to address a wide range of questions in macroeconomics and finance. This paper investigates a number of their testable implications which have not previously been explored. We show that the assumption that certain specified yields are priced without error is testable, and find that the implied measurement or specification error exhibits serial correlation in all of the possible formulations investigated here. We further find that the predictions of these models for the average levels of different interest rates are inconsistent with the observed data, and propose a more general specification that is not rejected by the data.
Relationship between Milk Microbiota, Bacterial Load, Macronutrients, and Human Cells during Lactation

Human breast milk is considered the optimal nutrition for infants, providing essential nutrients and a broad range of bioactive compounds, as well as its own microbiota. However, the interaction among those components and the biological role of milk microorganisms is still uncovered. Thus, our aim was to identify the relationships between milk microbiota composition, bacterial load, macronutrients, and human cells during lactation. Bacterial load was estimated in milk samples from a total of 21 healthy mothers through lactation time by bacteria-specific qPCR targeted to the single-copy gene fusA. Milk microbiome composition and diversity was estimated by 16S-pyrosequencing and the structure of these bacteria in the fluid was studied by flow cytometry, qPCR, and microscopy. Fat, protein, lactose, and dry extract of milk as well as the number of somatic cells were also analyzed. We observed that milk bacterial communities were generally complex, and showed individual-specific profiles. Milk microbiota was dominated by Staphylococcus, Pseudomonas, Streptococcus, and Acinetobacter. Staphylococcus aureus was not detected in any of these samples from healthy mothers. There was high variability in composition and number of bacteria per milliliter among mothers and in some cases even within mothers at different time points. The median bacterial load was 106 bacterial cells/ml through time, higher than those numbers reported by 16S gene PCR and culture methods. Furthermore, milk bacteria were present in a free-living, “planktonic” state, but also in equal proportion associated to human immune cells. There was no correlation between bacterial load and the amount of immune cells in milk, strengthening the idea that milk bacteria are not sensed as an infection by the immune system.
Evolving Cooperation in Complex Behavioral Interactions through Reputation Siang

The iterated prisoner’s dilemma (IPD) has long been used to study the conditions that promote cooperative behaviors among selfish individuals. In particular, studies using the co-evolutionary learning framework have shown that cooperative behaviors can be learned through a process of adaptation of strategies based solely on direct interactions through repeated encounters in playing IPD. However, complex behavioral interactions (e.g., by humans) may involve more than just direct interactions between two individuals. In many real-world situations, it is impossible to interact with all other individuals. It is very important to study indirect interactions, e.g., in the form of estimating behaviors of future partners through their perceived reputation based on previous behaviors to other individuals. Here, we study the co-evolutionary learning of IPD with reputation where behavioral interactions for a pair of strategies depend not only on choices made in their previous moves, but also choices made to other strategies that are reflected by their reputation scores. We show that for more complex IPD interactions involving more choices where direct interaction alone is ineffective to promote cooperation, the addition of reputation helps to promote cooperation. We further show that different implementations of reputation estimation, which reflect the accuracy of reputation estimation from using memory of games from previous generation and more frequent updating of reputation scores, is for the evolution of cooperation. Finally, we also investigate the situation where strategies can misperceive their partner’s reputation and show that even in the circumstances that strategies misperceive reputation, evolution to cooperation is still possible. This implies that reputation helps to increase the robustness of co-evolutionary learning of cooperative strategies.
Adaptive modulation for coded cooperative systems

Throughput plays a key role in data communications over a wireless link. In this paper, we use adaptive modulation for a cooperative relaying system with the goal of maximizing the data throughput. We compare the throughput performance of three different schemes with adaptive modulation: direct transmission, multihop and coded cooperation. We find that cooperation with adaptive modulation provides large throughput improvement over multihop and direct transmissions. We also observe that to maximize the data throughput in direct transmission and multihop, the modulation mode for each hop only depends on the channel quality from the transmitter to the receiver. However, in coded cooperation a system wide optimization is necessary.

Have State Renewable Portfolio Standards Really Worked? Synthesizing Past Policy Assessments to Build an Integrated Econometric Analysis of RPS effectiveness in the U.S.

Renewable portfolio standards (RPS) are the most popular U.S. state-level policy tools for promoting deployment of electricity from renewable energy (RES-E). While several econometric studies have estimated the effect of RPS policies on RES-E deployment, results are sometimes contradictory. Thus, there is a need to not only reconcile these studies but also establish a definitive answer to the question whether RPS policies have been effective in increasing RES-E deployment. We use a panel – 50 states over 1990-2010 – of renewable deployment, policy design elements and market dynamics to capture the heterogeneity in state RPS design and state characteristics. We run time series cross sectional regressions with fixed effects, and verify the causal effect implied by our results with a nonparametric matching analysis. We trace discrepancies among past findings to differences in data classification and model specification. We show that the key feature of RPS policies – RPS stringency – has no effect, and in some cases a negative effect, on RES-E deployment. We also investigate the impact of individual RPS features. We show that renewable energy certificate (REC) unbundling as well as the presence of RPS in neighboring states is correlated with greater RES-E deployment locally, while other features – such as allowing greater flexibility to buy renewable energy from out-of-state – slows in-state RES-E deployment. We show that mandatory green power options have a positive effect on RES-E deployment while net metering schemes appear to have a negative impact. However, we were unable to detect any impact of an interaction effect between RPS and these policies. Finally, we investigate the impact of policies on the deployment of individual renewable technologies (biomass, geothermal, solar, and wind) and demonstrate differentiated policy impacts, such as biomass driving the result on RPS stringency.

The proposed design overcomes the drawbacks of the dynamic logic family and uses explicit clock pulse generator approach to achieve dual edge triggering. The proposed flip-flop is compared with existing explicit pulsed dual edge triggered flip-flops. Based on the simulation results overall improvements of 12.67% and 10.15% are observed in delay and power delay product respectively.
Simulatable security for quantum protocols. (arXiv:quant-ph/0409125v2 CROSS LISTED)

The notion of simulatable security (reactive simulatability, universal composability) is a powerful tool for allowing the modular design of cryptographic protocols (composition of protocols) and showing the security of a given protocol embedded in a larger one. Recently, these methods have received much attention in the quantum cryptographic community. We give a short introduction to simulatable security in general and proceed by sketching the many different definitional choices together with their advantages and disadvantages. Based on the reactive simulatability modelling of Backes, Pfitzmann and Waidner we then develop a quantum security model. By following the BPW modelling as closely as possible, we show that composable quantum security definitions for quantum protocols can strongly profit from their classical counterparts, since most of the definitional choices in the modelling are independent of the underlying machine model. In particular, we give a proof for the simple composition theorem in our framework.
Antioxidant Effects of Some Drugs on Ethanol-induced Ulcers

The aim of this work was to investigate the antioxidant potential of some commonly used drugs (bromocriptine, haloperidol and azithromycin) on alcohol-induced ulcers in the rat. The following parameters were determined: content of reduced glutathione, activities of catalase, xanthine oxidase, glutathione reductase, glutathione peroxidase, peroxidase, and lipid peroxidation intensity. A battery of biochemical assays were used and the resulting data was statistically analyzed. Alcohol stress caused gastric ulcerations and hemorrhages and changed all the examined parameters except glutathione peroxidase activity. All drugs reduced the ulcer index and hemorrhages, with azithromycin showing the strongest effects. The drugs in combination with alcohol showed different effects on biochemical parameters. Our results indicate that the gastroprotective effects of the investigated drugs on experimental lesions induced by 100% ethanol could not be correlated with their antioxidative properties.
On the role of productive government spendings for convergence of a growing economy with heterogenous specialists

This paper employs a dynamic framework to compare the effects of alternative government activities on convergence of industrialized economies to the technology frontier. The government's Instruments include facilitating private investment and education policy. The latter enhances skills of heterogenous specialists and imply the decision on their respective shares. The analysis distinguishes between an isolated policy of a single economy and coordinated policies of various countries. Which policy maximizes the speed of convergence is crucially affected by the economy's state of development. A policy switch between the mentioned instruments while catching-up may be preferable.
Estimates for viscosity solutions of parabolic equations with Dirichlet boundary conditions

It is shown how one can get upper bounds for |u - v| when u and v are the (viscosity) solutions of u t - α(D x u)Δ x u = 0 and v t - β(D x v)Δ x v = 0, respectively, in (0, oo) × Ω with Dirichlet boundary conditions. Similar results are obtained for some other parabolic equations as well, including certain equations in divergence form.
Molecular gas and star formation in the red-sequence counter-rotating disc galaxy NGC 4550

We present observations of the CO(1-0) emission in the central 750 pc (10 arcsec) of the counter-rotating disc galaxy NGC 4550, obtained at the Institut de Radioastronomie Millimetrique (IRAM) Plateau de Bure Interferometer. Very little molecular gas is detected, only 1 ×10 7 M ⊙ , and its distribution is lopsided, with twice as much molecular gas observed at positive relative velocities than at negative relative velocities. The velocity gradient in the CO(1-0) emission shows that the molecular gas rotates like the thicker of the two stellar discs, which is an unexpected alignment of rotations if the thinner disc was formed by a major gas accretion event. However, a simulation shows that the gas rotating like the thicker disc naturally results from the coplanar merger of two counter-rotating disc galaxies, demonstrating the feasibility of this scenario for the formation of NGC 4550. We investigate various star formation tracers to determine whether the molecular gas in NGC 4550 is currently forming stars. Ultraviolet (UV) imaging data and optical absorption line strengths both suggest a recent star formation episode; the best-fitting two-population model to the UV-optical colours yields a mass of young stars of 5.9×10 7 M ⊙ with an age of 280 Myr. The best information on the current star formation rate is a far-infrared-based upper limit of only 0.02 M ⊙ yr -1 . We are thus witnessing NGC 4550 either in a dip within a bursty star formation period or during a more continuous low-level star formation episode.
Tonality detection methods for wheezes recognition system

In this paper a comparison of some known and new features used for signal tonality detection in pulmonary wheezes recognition systems is presented. In the article, the Tonal Index is compared to Kurtosis (K), Energy Ratio (ER), two types of correlation feature (CF), Difference to Mean ratio (D2M), Eigen Value Decomposi-tion feature (EVD) and Linear Prediction feature (LP). The analy-sis of efficiency related to complexity of descriptors is presented as well. Experiments have been conducted on artificially generated wheezes-like signals that have been embedded in real pulmonary noise (a hybrid signal) as well as on recorded real wheezes.
Warrant Pricing Bias in China's Stock Market and Its Causes

In this paper we study the characteristics of warrant prices and their formation in China's stock market. We use Hull-White option pricing model (H-W model) to investigate the characteristics of warrant prices, and then adopt the behavior finance theories to study the formation of these characteristics. Our study results show that: all sample warrants have great pricing biases; out-of-the-money warrants are overpriced while in-the-money warrants are underpriced; overpricing of the out-of-the-money call warrant becomes more serious along with the underlying stock price falling; the investors' overconfidence and their overrating of the probabilities of low-probability events are two main causes of these phenomena.
On endomorphism rings and dimensions of local cohomology modules

Let (R, m) denote an n-dimensional complete local Gorenstein ring. For an ideal I of R let H i I (R),i ∈ Z, denote the local cohomology modules of R with respect to I. If H i I (R) = 0 for all i ≠ c = height I, then the endomorphism ring of H c I (R) is isomorphic to R. Here we prove that this is true if and only if H i I (R) = 0 for i = n, n - 1, provided c ≥ 2 and R/I has an isolated singularity, resp. if I is set-theoretically a complete intersection in codimension at most one. Moreover, there is a vanishing result of H i I (R) for all i > m, m a given integer, and an estimate of the dimension of H i I (R).
