description: The internal electric field within a piezoelectric material can effectively inhibit the recombination of photogenerated electron–hole pairs, thus serving as a means to enhance photocatalytic efficiency. Herein, we synthesized a Na₀.₅Bi₄.₅Ti₄O₁₅ (NBT) catalyst by the hydrothermal method and optimized its catalytic performance by simple high-voltage poling. When applying light and mechanical stirring on a 2 kV mm⁻¹ poled NBT sample, almost 100% of Rhodamine B solution could be degraded in 120 min, and the reaction rate constant reached as high as 28.36 × 10⁻³ min⁻¹, which was 4.2 times higher than that of the unpoled NBT sample. The enhanced piezo-photocatalytic activity is attributed to the poling-enhanced internal electric field, which facilitates the efficient separation and transfer of photogenerated carriers. Our work provides a new option and idea for the development of piezo-photocatalysts for environmental remediation and pollutant treatment.
Removal of chromium hexavalent (Cr(VI) from aqueous solution using activated carbon prepared from Prosopis Juliflora Plant and find the optimal operating condition for adsorption process

description: In the present study adsorption of chromium (VI) ions from aqueous solution by activated carbon

prepared from Prosopis Juliflora plant was investigated under batch mode. The removal of

hexavalent chromium was optimized by using response surface methodology. The influence of

various process parameters such as initial chromium (VI) concentration, solution pH, sorbent

dose and contact time on the removal process were investigated. A total of 30 sorption

experimental runs were carried out employing the detailed conditions designed by response

surface methodology based on the Central Composite Design. The analysis of variance

(ANOVA) depicted that the quadratic model was suitable for the responses. Contour and

response surface plots were used to determine the interaction effects of main factors and

optimum conditions of process, respectively

description: We analyse the influence of heat generation by non radiative transitions in high power 1.55$μ$m double cladding Erbium-Ytterbium fiber laser. At strong pumping rates, 1$μ$m lasing can start due to parasitic reflections. We present a model including heat generation and its effect on the Stark level population using the MacCumber relation. Heat generation plays then a significant role and improves the 1.5$μ$m laser efficiency by increasing the 1$μ$m threshold.

description: This paper explores official trade data to identify patterns of smuggling in international trade. Our main measure of interest is the difference in matched partner trade statistics, i.e., the extent to which the recorded export value in the source country deviates from the reported import value in the destination country. Analyzing 4-digit product level data for the world’s five largest importers for the period from 2002-2006, we find that the reporting gaps are highly correlated with the level of corruption in both partner countries. This finding supports the hypothesis that trade gaps partly represent smuggling activities.

description: In this note, we use multivariate models estimated with Bayesian techniques and an out-ofsample approach to investigate whether money growth Granger- causes output growth in the United States. We find surprisingly strong evidence for a money-output link over the 1960-2005 period. However, further analysis indicates that this result is likely to be misleading; after the ‘Great moderation’, the Granger-causal role of money appears to have vanished completely.

description: Background
 Antimicrobial resistance is an increasing problem every year. It is an urgent condition that needs to be resolved. Most of the reasons are personnel lack of knowledge. There is a misconception that broad spectrum antibiotics are always better. Therefore, we set up a multidisciplinary antimicrobial drug resistance(AMR) team round aiming to educate healthcare personnel to manage antimicrobial resistance, improve patient safety and develop interprofessional education in our institute, too.
 Summary of work
 We set up the AMR team round, which consisted of infectious disease doctors to evaluate and suggest antibiotics for each patient, pharmacists to adjust dose antibiotics, microbiologists to report drug sensitivity and improve culture technique, and infection control nurses to care of patient with multidrug resistance. Then, we develop workshop teaching and learning about antimicrobial drug resistance with internists and 6th -year medical students. AMR team round will visit patients, receiving broad spectrum antibiotics, discussion with internist and 6th year medical student and determine the appropriate antibiotics for each patient, every two days per week. The questionnaire was used to evaluate the advantage, satisfaction and suggestion of AMR team round from health care personnel.
 Summary of results
 All questionnaires were responded 210 healthcare personnel, including 15 externs, 21 interns, 10 pharmacists, and 164 nurses. The mean of satisfaction and advantage score were 4.3(±0.7) and 4.5(±0.7), rating score between 1-5. The mean of confidence when prescribe antibiotics from externs were 3.3(±1.0) and from interns were 3.6(±0.7) p=0.430. Most participants agreed that AMR team round was advantage, important and necessary for improving patient safety and managing antimicrobial drug resistance.
 Discussion and conclusions
 The AMR team round is a model for interprofessional education that is improving knowledge, appropriate use antibiotics, and working together to reduce antimicrobial drug resistance and enhance patient safety from all healthcare personnel in our institute.

Reduced magnetohydrodynamic theory of oblique plasmoid instabilities

description: The three-dimensional nature of plasmoid instabilities is studied using the reduced magnetohydrodynamic equations. For a Harris equilibrium with guide field, represented by $\vc{B}_o = B_{po} \tanh (x/λ) \hat{y} + B_{zo} \hat{z}$, a spectrum of modes are unstable at multiple resonant surfaces in the current sheet, rather than just the null surface of the polodial field $B_{yo} (x) = B_{po} \tanh (x/λ)$, which is the only resonant surface in 2D or in the absence of a guide field. Here $B_{po}$ is the asymptotic value of the equilibrium poloidal field, $B_{zo}$ is the constant equilibrium guide field, and $λ$ is the current sheet width. Plasmoids on each resonant surface have a unique angle of obliquity $θ\equiv \arctan(k_z/k_y)$. The resonant surface location for angle $θ$ is $x_s = - λ\arctanh (\tan θB_{zo}/B_{po})$, and the existence of a resonant surface requires $|θ| < \arctan (B_{po} / B_{zo})$. The most unstable angle is oblique, i.e. $θ\neq 0$ and $x_s \neq 0$, in the constant-$ψ$ regime, but parallel, i.e. $θ= 0$ and $x_s = 0$, in the nonconstant-$ψ$ regime. For a fixed angle of obliquity, the most unstable wavenumber lies at the intersection of the constant-$ψ$ and nonconstant-$ψ$ regimes. The growth rate of this mode is $γ_{\textrm{max}}/Γ_o \simeq S_L^{1/4} (1-μ^4)^{1/2}$, in which $Γ_o = V_A/L$, $V_A$ is the Alfvén speed, $L$ is the current sheet length, and $S_L$ is the Lundquist number. The number of plasmoids scales as $N \sim S_L^{3/8} (1-μ^2)^{-1/4} (1 + μ^2)^{3/4}$.

description: How many people should decide about monetary policy? In this paper, we take an empirical perspective on this issue, analyzing the relationship between the number of monetary policy decisionmakers and monetary policy outcomes. Using a new data set that characterizes Monetary Policy Committees (MPCs) in more than 30 countries from 1960 through 2000, we find a U-shaped relation between the membership size of MPCs and inflation; our results suggest that the lowest level of inflation is reached at MPCs with about seven to ten members. Similar results are obtained for other measures, such as inflation variability and output growth. We also find that MPC size influences the success of monetary targeting regimes. In contrast, there is no evidence that either turnover rates of MPC members or the membership composition of MPCs affect economic outcomes.

They are described by spectral triples (A_θ, \H, D), with the Dirac operator D, which is a differential operator with coefficients in the commutant of the (smooth) algebra A_θof T_θ. We show, up to the second order in perturbation, that the zeta-function at 0 vanishes and so the Gauss-Bonnet theorem holds. We also calculate first two terms of the perturbative expansion of the corresponding local scalar curvature.

description: We use Bayesian estimation techniques to investigate whether money growth Granger-causes inflation in the United States. We test for Granger-causality out-of-sample and find, perhaps surprisingly given recent theoretical arguments, that including money growth in simple VAR models of inflation does systematically improve out-of-sample forecasting accuracy. This holds for a long forecasting sample 1960-2005, as well for more recent subperiods, including the Volcker and Greenspan eras. However, the contribution of money to inflation forecasting accuracy is quantitatively limited and tends to be smaller in recent subperiods, in particular in models that also include information on real GDP growth and interest rates.

description: We consider probability measures supported on a finite discrete interval $[0,n]$. We introduce a new finitedifference operator $\nabla_n$, defined as a linear combination of left and right finite differences. We show that this operator $\nabla_n$ plays a key role in a new Poincaré (spectral gap) inequality with respect to binomial weights, with the orthogonal Krawtchouk polynomials acting as eigenfunctions of the relevant operator. We briefly discuss the relationship of this operator to the problem of optimal transport of probability measures.

description: We use a mean-adjusted Bayesian VAR model as an out-of-sample forecasting tool to test whether money growth Granger-causes inflation in the euro area. Based on data from 1970 to 2006 and forecasting horizons of up to 12 quarters, there is surprisingly strong evidence that including money improves forecasting accuracy. The results are very robust with regard to alternative treatments of priors and sample periods. That said, there is also reason not to overemphasize the role of money. The predictive power of money growth for inflation is substantially lower in more recent sample periods compared to the 1970s and 1980s. This cautions against using money-based inflation models anchored in very long samples for policy advice.

We calculate the time dependence of the Neumann entropy of the one-particle reduced density matrix. By using the exact propagator for the delta potential, we derive an approximate analytic formula for the asymptotic form of the two-particle wave function which is sufficiently accurate to account for the entanglement features of the system.

description: Through a combined experimental and theoretical approach, we study the nonadiabatic dynamics of the prototypical ethylene (C$_2$H$_4$) molecule upon $π\rightarrow π^*$ excitation with 161 nm light. Using a novel experimental apparatus, we combine femtosecond pulses of vacuum ultraviolet (VUV) and extreme ultraviolet (XUV) radiation with variable delay to perform time resolved photo-ion fragment spectroscopy. In this second part of a two part series, the extreme ultraviolet (17 eV$ < h ν< 23$ eV) probe pulses are sufficiently energetic to break the C-C bond in photoionization, or photoionize the dissociation products of the vibrationally hot ground state. The experimental data is directly compared to ab initio molecular dynamics simulations accounting for both the pump and probe steps. Enhancements of the CH$_2^+$ and CH$_3^+$ photoion fragment yields, corresponding to molecules photoionized in ethylene (CH$_2$CH$_2$) and ethylidene (CH$_3$CH) like geometries are observed within 100 fs after $π\rightarrow π^*$ excitation. Quantitative agreement between theory and experiment on the relative CH$_2^+$ and CH$_3^+$ yields provides experimental confirmation of the theoretical prediction of two distinct transition states and their branching ratio (Tao, et al. J. Phys. Chem. A. 113, 13656 (2009)). Fast, non-statistical, elimination of H$_2$ molecules and H atoms is observed in the time resolved H$_2^+$ and H$^+$ signals.

description: The paper shows that there is a substantial degree of heterogeneity in the ability of Fed watchers to forecast US monetary policy decisions. Based on a novel database for 268 professional forecasters since 1999, the average forecast error of FOMC decisions varies 5 to 10 basis points between the best and worstperformers across the sample. This heterogeneity is found to be related to both the skills of analysts – such as their educational and employment backgrounds – and to geography. In particular, forecasters located in regions which experience more idiosyncratic economic conditions perform worse in anticipating monetary policy. This evidence is indicative that limited attention and heterogeneous priors are present even for anticipating important events such as monetary policy decisions. Moreover, the paper shows that such heterogeneity is economically important as it leads to greater financial market volatility after FOMC meetings. Finally, policy-makers are not impotent in influencing such heterogeneity as Fed communication is found to affect forecast accuracy significantly.

description: We present a unifying scenario to address the physical origin of the diversity of X-ray lightcurves within the rho variability class of the microquasar GRS 1915+105. This 'heartbeat' state is characterized by a bright flare that recurs every ~50-100 seconds, but the profile and duration of the flares varies significantly from observation to observation. Based on a comprehensive, phase-resolved study of heartbeats in the RXTE archive, we demonstrate that very different X-ray lightcurves do not require origins in different accretion processes. Indeed, our detailed comparison of the phase-resolved spectra of a double-peaked oscillation and a single-peaked oscillation shows that different cycles can have basically similar X-ray spectral evolution. We argue that all heartbeat oscillations can be understood as the result of a combination of a thermal-viscous radiation pressure instability, a local Eddington limit in the disk, and a sudden, radiation-pressure-driven evaporation or ejection event in the inner accretion disk. This ejection appears to be a universal, fundamental part of the rho state, and is largely responsible for a hard X-ray pulse seen in the lightcurve of all cycles. We suggest that the detailed shape of oscillations in the mass accretion rate through the disk is responsible for the phenomenological differences between different rho-type lightcurves, and we discuss how future time-dependent simulations of disk instabilities may provide new insights into the role of radiation pressure in the accretion flow.

description: This paper explores the factors behind the time path of real spending and revenue in the West German states from 1975 to 2004. The empirical approach stresses robustness and takes into account a large set of economic and political variables. Our results suggest that common economic factors and, to a smaller degree, state-specific economic developments are important determinants of state fiscal performance. In comparison, the influence of political factors is limited both in statistical and quantitative terms. Finally, there is evidence that addressing governance problems and ensuring flexibility in terms of fiscal strategy are important ingredients for any policy aimed at improving fiscal outcomes at the state level.

description: Global excess liquidity roaming the world’s financial markets (or its sudden absence) is sometimes believed to limit sovereign monetary policy even in large economies such as the euro area. However, there is still discussion about what constitutes global excess liquidity and how exactly it shapes the policy environment. Our approach adjusts liquidity for longerterm interest rate and output effects and focuses on U.S. and Japanese liquidity as relevant proxies for global developments from a euro area perspective. We find that both excess liquidity in Japan and, in particular, the U.S. tend to lead developments in euro area liquidity. U.S. excess liquidity also enters consistently positive as a determinant of euro area inflation and is shown to be Granger-causal for euro area inflation in an out-of-sample forecasting exercise. In part, this result seems to be related to a weakening of the euro area interest rate channel during times of excessive U.S. liquidity. In contrast, the influence of Japanese and euro area excess liquidity on euro area inflation is more limited.

As an example we consider the thermoelectric coefficients of the diluted two-dimensional electron gas in Si(100) MOSFET's in the presence of charged-impurity scattering. We find that the screening anomaly at $q=2k_F$, also responsible for Friedel oscillations, leads at low electron densities to a large change in the thermoelectric coefficient for the thermopower.

description: Monetary aggregates continue to play an important role in the ECB’s policy strategy. This paper revisits the case for money, surveying the ongoing theoretical and empirical debate. The key conclusion is that an exclusive focus on non-monetary factors alone may leave the ECB with an incomplete picture of the economy. However, treating monetary factors as a separate matter is a second-best solution. Instead, a general-equilibrium inspired analytical framework that merges the economic and monetary “pillars” of the ECB’s policy strategy appears the most promising way forward. The role played by monetary aggregates in such unified framework may be rather limited. However, an integrated framework would facilitate the presentation of policy decisions by providing a clearer narrative of the relative role of money in the interaction with other economic and financial sector variables, including asset prices, and their impact on consumer prices.

description: This paper contributes to the debate on the role of money in monetary policy by analyzing the information content of money in forecasting euro-area inflation. We compare the predictive performance within and among various classes of structural and empirical models in a consistent framework using Bayesian and other estimation techniques. We find that money contains relevant information for inflation in some model classes. Money-based New Keynesian DSGE models and VARs incorporating money perform better than their cashless counterparts. But there are also indications that the contribution of money has its limits. The marginal contribution of money to forecasting accuracy is often small, money adds little to dynamic factor models, and it worsens forecasting accuracy of partial equilibrium models. Finally, non-monetary models dominate monetary models in an all-out horserace.

description: Microfoundations of the euro’s effect on euro area trade hinge on the timing, the speed and the size of adjustment in trade costs. We estimate timing, speed and size of adjustment in trade costs for sectoral trade data. Our approach allows for sector specific impacts of trade costs on sectoral trade while controlling for unobserved but time-variant variables at the sector level. We find that, due to falling trade costs, trade within the euro area increases between the years 2000 and 2003 by 10 to 20 percent compared with trade between European countries that are not members of the euro area. Adjustment of individual sectors is extremely fast whereas aggregate adjustment spreads out because different sectors adjust at distinct times.

description: From a normative perspective, it is striking that the degree of central bank independence (CBI) varies considerably across countries. Taking a political economy perspective, this paper demonstrates how different degrees of CBI may be the result of ‘strategic policy-making’. While an independent central bank reduces the incumbent politician’s chances to influence current monetary policy it also raises the costs of future policy changes for political successors. Hence, when deciding on the degree of CBI, incumbent politicians face a trade-off: current influence on monetary policy versus policy durability. This paper shows how various factors change this trade-off and hence the institutional choice. The model predicts that the level of CBI incumbent politicians choose will increase in politicians’ ability to screen central bankers’ preferences, in the degree of political polarization, and in the weight politicians place on future policy outcomes. In contrast, the likelihood for the implementation of an independent central bank decreases in the re-election prospects of incumbents and in the utility central bankers receive from holding office.

description: During earthquakes preparation periods significant disturbances in the ionospheric plasma density are often observed. These anomalies are caused by lithosphere-atmosphere-ionosphere interaction, particularly by the seismic electric field penetrating from the ground surface into the ionosphere. The seismic electric field produces electromagnetic EB drift changing plasma density over the epicenter region and magnetically conjugated area. The paper is devoted to analysis of regular Global Positioning System observations and revelation of seismo-ionospheric precursors of earthquakes in Total Electron Content (TEC) of the ionosphere. Global and regional relative TEC disturbances maps (%) have been plotted for 2005-2006 M6, D<60 km seismic events and analyzed in order to determine general features of precursors. The obtained results agree with the recent published case-study investigations.

Exit options in incomplete contracts with asymmetric information

subject: Asymmetric Information
subject: Exit Options
subject: 300 Sozialwissenschaften::330 Wirtschaft::338 Produktion

description: This paper analyzes bilateral contracting in an environment with contractual incompleteness and asymmetric information. One party (the seller) makes an unverifiable quality choice and the other party (the buyer) has private information about its valuation. A simple exit option contract, which allows the buyer to refuse trade, achieves the first–best in the benchmark cases where either quality is verifiable or the buyer’s valuation is public information. But, when unverifiable and asymmetric information are combined, exit options induce inefficient pooling and lead to a particularly simple contract. Inefficient pooling is unavoidable also under the most general form of contracts, which make trade conditional on the exchange of messages between the parties. Indeed, simple exit option contracts are optimal if random mechanisms are ruled out.

Secure and Privacy- Aware Searching in Peer-to-Peer Networks

description: The existing peer-to-peer networks have several problems such as fake content distribution, free riding, white-washing and poor search scalability, lack of a robust trust model and absence of user privacy protection mechanism. Although, several trust management and semantic community-based mechanisms for combating free riding and distribution of malicious contents have been proposed by some researchers, most of these schemes lack scalability due to their high computational, communication and storage overhead. This paper presents a robust trust management scheme for P2P networks that utilizes topology adaptation by constructing an overlay of trusted peers where the neighbors are selected based on their trust ratings and content similarities. While increasing the search efficiency by intelligently exploiting the formation of semantic community structures by topology adaptation among the trustworthy peers, the scheme provides the users a very high level of privacy protection of their usage and consumption patterns of network resources. Simulation results demonstrate that the proposed scheme provides efficient searching to good peers while penalizing the malicious peers by increasing their search times as the network topology stabilizes.

description: Il secondo volume della collana “Quaderni del LUDiCa” dà conto degli esiti delle edizioni 2020 e 2021 del LUDiCa, il laboratorio di umanistica digitale dell’Università di Cagliari. Due edizioni che si sono tenute a distanza a causa della pandemia da Covid-19. L’improvvisa e inattesa piega presa dagli eventi ha portato al ripensamento integrale del flusso di lavoro, per adattarlo alla nuova “distanza” digitale imposta dalle contingenze. Condurre una ricerca d’ambito umanistico da remoto, con attrezzi digitali, e percorrere l’intera filiera che consente di trasformare un insieme sparso di dati in un oggetto informativo strutturato e pubblicato digitalmente è stato difficile, ma ha dato vita a esperienze molto formative, ricche di spunti ed esiti di interessanti e per tanti versi inattesi. Questi esiti formano il centro del racconto di questo volume, come sempre curato direttamente da coloro che sono stati protagonisti del laboratorio.

description: Unter den Einrichtungen der Erwachsenenbildung nehmen die Volkshochschulen den ersten Platz ein. Jede einzelne davon bemüht sich, ihren Hörern ein möglichst breitgefächertes, aktuelles Angebot zu unterbreiten, das vom türkischen Bauchtanz über Lichtbogenschweißen bis zum Lehrgang über französische Weine reichen kann. Etwa ein Drittel des Programms entfällt auf den Fremdsprachenunterricht. Neben Englisch und Französisch, das überall gelehrt wird, haben 73 Volkshochschulen auch Kurse in Chinesisch eingeführt. An sie ging Mitte Juni der Fragebogen. Vierzig der Fachbereichsleiter für die Abteilung Sprachen haben ihn ausgefüllt zurückgesandt oder ihre Angaben telefonisch übermittelt. Beim Durchlesen der Antworten fällt auf, daß viele Volkshochschulen begleitende Veranstaltungen wie Vorträge zu Kultur und Landeskunde, Kalligraphie und Kochen anbieten. 15 bekunden Interesse an einem noch zu entwickelnden Zertifikat, wie es für viele andere Sprachen bereits besteht. Wir sollten diesen Punkt auf unserer nächsten Versammlung einmal erörtern. Mein herzlicher Dank gilt dem Kessler-Verlag/Bonn, der mir die Adressen der Volkshochschulen mit Chinesischunterricht zur Verfügung stellte und damit diese Umfrage erst ermöglichte.
