description: The values and energy dependence for the survival probability $< \mid S\mid^2 >$ of large rapidity gaps (LRG) are calculated in a three channel model. This model includes single and double diffractive production, as well as elastic rescattering. It is shown that $< \mid S \mid^2 >$ decreases with increasing energy, in line with recent results for LRG dijet production at the Tevatron. This is in spite of the weak dependence on energy of the ratio $ (σ_{el}+ σ_{SD})/σ_{tot}$.

description: We explore the connection between starspots and plages of three main-sequence stars by studying the chromospheric and photospheric activity over several rotation periods. We present simultaneous photometry and high-resolution ($R\sim 31,500$) spectroscopy of KIC 9652680, a young, superflare-producing G1 star with a rotation period of 1.4 days. Its Kepler light curve shows rotational modulation consistent with a bright hemisphere followed by a relatively dark hemisphere, generating photometric variability with a semi-amplitude of 4%. We find that KIC 9652680 is darkest when its $S$-index of Ca II H & K emission is at its maximum. We interpret this anti-correlation between flux and $S$ to indicate that dark starspots in the photosphere are co-located with the bright plages in the chromosphere, as they are on the Sun. Moving to lower masses and slower rotators, we present K2 observations with simultaneous spectroscopy of EPIC 211928486 (K5V) and EPIC 211966629 (K4V), two active stars in the 650 Myr-old open cluster Praesepe. The K2 photometry reveals that both stars have rotation periods of 11.7 days; while their flux varies by 1 and 2% respectively, their Ca II H & K $S$-indices seem to hold relatively constant as a function of rotational phase. This suggests that extended chromospheric networks of plages are not concentrated into regions of emission centered on the starspots that drive rotational modulation, unlike KIC 9652680. We also note that the Ca II emission of EPIC 211928486 dipped and recovered suddenly over the duration of one rotation, suggesting that the evolution timescale of plages may be of order the rotation period.

description: A time series model in which the signal is buried in noise that is non-Gaussian may throw up observations that, when judged by the Gaussian yardstick, are outliers. We describe an observation driven model, based on an exponential generalized beta distribution of the second kind (EGB2), in which the signal is a linear function of past values of the score of the conditional distribution. This specification produces a model that is not only easy to implement, but which also facilitates the development of a comprehensive and relatively straight-forward theory for the asymptotic distribution of the maximum likelihood estimator. The model is fitted to US macroeconomic time series and compared with Gaussian and Student-t models. A theory is then developed for an EGARCH model based on the EGB2 distribution and the model is fitted to exchange rate data. Finally dynamic location and scale models are combined and applied to data on the UK rate of inflation.

description: An ac field, tuned exactly to resonance with the Stark ladder in an ideal tight binding lattice under strong dc bias, counteracts Wannier-Stark localization and leads to the emergence of extended Floquet states. If there is random disorder, these states localize. The localization lengths depend non-monotonically on the ac field amplitude and become essentially zero at certain parameters. This effect is of possible relevance for characterizing the quality of superlattice samples, and for performing experiments on Anderson localization in systems with well-defined disorder.

description: Two schemes of mixing of four massive neutrinos with two couples of close neutrino masses separated by a gap of the order of 1 eV can accommodate solar, atmospheric and LSND neutrino oscillation data. It is shown that long-baseline nu(e)->nu(e) and nu(mu)->nu(e) transitions are strongly suppressed in these schemes. The scheme of mixing of three neutrino masses with a mass hierarchy that can describe solar and atmospheric neutrino data is also discussed. It is shown that in this scheme the effective Majorana mass || that characterizes the matrix element of neutrinoless double-beta decay is less than 10^{-2} eV.

We study the largest minimum weight $d(n,k)$ among all binary linear complementary dual $[n,k]$ codes. We determine $d(n,4)$ for $n \equiv 2,3,4,5,6,9,10,13 \pmod{15}$, and $d(n,5)$ for $n \equiv 3,4,5,7,11,19,20,22,26 \pmod{31}$. Combined with known results, the values $d(n,k)$ are also determined for $n \le 24$.

description: We show that the abelian topological mass mechanism in four dimensions, described by the Cremmer-Sherk action, can be obtained from dimensional reduction in five dimensions. Starting from a gauge invariant action in five dimensions, where the dual equivalence between a massless vector field and a massless second-rank antisymmetric field in five dimensions is established, the dimensional reduction is performed keeping only one massive mode. Furthermore, the Kalb-Ramond action and the Stuckelberger formulation for massive spin-1 are recovered.

Time Series Momentum Trading Strategy and Autocorrelation Amplification

Publisher: name: Faculty of Economics
Year: 2013

description: This article assumes general stationary processes for prices and derives the autocorrelation function for a general Moving Average (MA) trading rule to investigate why this rule is used. The result shows that the MA rule is popular because it can identify price momentum and is a simple way of tracing and exploiting price autocorrelation structure without necessarily knowing its precise structure. We focus on analyzing the impact of price momentum on the profitability of the MA rule because the price momentum effect tends to be stronger and more persistent than the return momentum effect.

description: By its very nature, the outcomes of modern armed conflicts are increasingly being determined by political rather than purely military considerations. To support the politics of initiating and continuing to wage war in the current political environment requires a perception and sense of legitimacy and righteousness, whether the basis of this is or is not based upon actual and not projected reality. In an age of an increasingly cynical attitude towards both mainstream politics and mainstream media, a new and “independent” source of information is found in the NGOs in shaping the information space of modern battlefields in order to affect public perception and opinion of these events, which is illustrated with examples from Ukraine and Syria.

description: Despite their popularity, many questions about the algebraic constraints imposed by linear structural equation models remain open problems. For causal discovery, two of these problems are especially important: the enumeration of the constraints imposed by a model, and deciding whether two graphs define the same statistical model. We show how the half-trek criterion can be used to make progress in both of these problems. We apply our theoretical results to a small-scale model selection problem, and find that taking the additional algebraic constraints into account may lead to significant improvements in model selection accuracy.

Restricting to the case in which this subvariety is a complete intersection, we present a sufficient condition for a smoothing of $X$ to exist inside $Y$. We exhibit a relative anti-canonical divisor for this smoothing of $X$, and show that the general member is simple normal crossings.

description: We re-analyse the prospects of discovering supersymmetry at the LHC, in order to re-express coverage in terms of a fine-tuning parameter and to extend the analysis to scalar masses (m_0) above 2 TeV. We use minimal supergravity (mSUGRA) unification assumptions for the SUSY breaking parameters. The discovery reach at high m_0 is of renewed interest because this region has recently been found to have a focus point, leading to relatively low fine-tuning, and because it remains uncertain how much of the region can be ruled out due to lack of radiative electroweak symmetry breaking. The best fine tuning reach is found in a mono-leptonic channel, where for mu>0, A_0=0 and tan beta=10 (within the focus point region), and a top mass of 174 GeV, all points in mSUGRA with m_0 < 4000 GeV, with a fine tuning measure up to 210 (500) are covered by the search, where the definition of fine-tuning excludes (includes) the contribution from the top Yukawa coupling. Even for arbitrarily high m_0, mSUGRA can be discovered through gaugino events, provided the gaugino mass parameter M_1/2 < 460 GeV. In this region, the mono-leptonic channel still provides the best reach.

description: Optical bistability of exciton polaritons in semiconductor microcavities is a promising platform for digital optical devices. Steady states of coherently driven polaritons can be toggled in tens of picoseconds by a short external pulse of appropriate amplitude and phase. We have analyzed the switching behavior of polaritons depending on the pulse amplitude, phase, and duration. The switches are found to change dramatically when the inverse pulse duration becomes comparable to the frequency detuning between the driving field and polariton resonance. If the detuning is large compared to the polariton linewidth, the system becomes extremely sensitive to initial conditions and thus can serve as a fast random-number generator.

IV Estimation of Panels with Factor Residuals

Subjects: Factor Residuals.

description: This paper proposes a new instrumental variables approach for consistent and asymptotically efficient estimation of panel data models with weakly exogenous or endogenous regressors and residuals generated by a multifactor error structure. In this case, the standard dynamic panel estimators fail to provide consistent estimates of the parameters. The novelty of our approach is that we introduce new parameters to represent the unobserved covariances between the instruments and the factor component of the residual; these parameters are estimable when N is large. Some important estimation and identification issues are studied in detail. The finite sample performance of the proposed estimators is investigated using simulated data. The results show that the method produces reliable estimates of the parameters over several parametrisations.
Fuel Panics - insights from spatial agent-based simulation

description: The United Kingdom has twice suffered major disruption as a result of fuel panics first in September 2000 coincident with a wave of fuel protests and more recently in March 2012 following politcal warnings of possible future supply chain disruption. In each case the disruption and economic consequences were serious. Fuel distribution is an example of a supply chain. Approaches to supply-chain planning based on linear programming are poorly suited to modelling non-equilibrium effects, while coarse-grained system dynamics models often fail to capture local phenomena which contribute to the evolution of global demand. In this Paper, we demonstrate that agent-based techniques offer a powerful framework for cosimulation of supply chains and consumers under conditions of transient demand. In the case of fuel panic crisis, we show that even a highly abstract model can reproduce a range of transient phenomena seen in the real world, and present a set of practical recommendations for policymakers faced with panic-buying.

description: There have been several attempts at democratic revolution in recent years. Some of these have succeeded, but others have failed. Why? A key factor in determining the success or failure of attempts at democratic revolution is the role played by the old regime's security services. If the security services defend the old regime, then the largely unarmed democratic opposition cannot come to power. But if the security services defect to the democratic opposition, then the old regime cannot survive. Further, the defection of the security services in democratic revolutions often begins with the defection of just a few officers that then cascades into a large-scale defection in just a very short period of time.
Anomalously slow relaxation in the diluted Ising model below the percolation threshold

description: The relaxational behaviour of the bond-diluted two-dimensional Ising model below the percolation threshold is studied using Monte Carlo techniques. The non-equilibrium decay of the magnetization,M(t), and the relaxation of the equilibrium spin-spin autocorrelation function, C(t), are monitored. The behaviour of both C(t) and M(t) is found to satisfy the Kohlrausch law of a stretched exponential with the same temperature-dependent exponent. The Kohlrausch exponent does not appear to depend on the bond concentration. The results indicate that we are not yet in the asymptotic regime, even when C(t) and M(t) are less than 10^{-4}.

Turnover Rate
Empathy Fatigue

description: The escalating demand for nurses in Japan, driven by factors such as the impact of new coronavirus infections and an aging population, has led to a surge in the number of nursing schools and universities. Despite a seemingly full university enrollment era attributed to a declining population under 18 years, the nursing workforce continues to expand, totaling approximately 1.27 million according to the Japan Nurses Association. However, the profession grapples with a persistent challenge – a high turnover rate among nurses.

This study delves into the intricacies of the nursing profession in Japan, with a particular focus on the factors contributing to the high turnover rate. Notably, nurses often internalize others' distress, leading to empathy fatigue and self-negative cognitions due to secondary stress. This phenomenon has been identified as a significant precursor to burnout, underscoring the critical need for self-compassion in the nursing domain.

The research aims to explore the relationship between empathy fatigue, self-negative cognitions, and the resultant burnout experienced by nurses in Japan. Drawing on existing literature and empirical data, the study investigates the psychological toll of continuously perceiving others' distress as one's own and its implications for the well-being and job satisfaction of nurses. Furthermore, the research will delve into the role of self-compassion as a potential mitigating factor against burnout in the nursing profession.

Understanding the unique challenges faced by nurses in Japan is crucial for the development of targeted interventions and support mechanisms. By shedding light on the psychological aspects contributing to the high turnover rate, this study aspires to inform policies and practices that foster a more compassionate and sustainable work environment for nurses. The findings are anticipated to contribute not only to the improvement of nurses' well-being but also to the overall enhancement of healthcare services in the country.

description: Using the 135-second cadence of the photospheric vector data provided by the Helioseismic and Magnetic Imager telescope on board the Solar Dynamic Observatory, we examined the time-evolution of magnetic helicity fluxes across the photosphere during 16 flares with the energy class lower than M5.0. During the flare in 4 out of 16 events, we found impulsive changes in the helicity fluxes. This indicates that even the flare with less energy could be associated with anomalistic transportation of the magnetic helicity across the photosphere. Accompanying the impulsive helicity fluxes, the poynting fluxes across the photosphere evolved from positive to negative. As such, the transportations of magnetic energy across the photosphere were toward solar interior during these flares. In each of the 4 events, the impulsive change in the helicity flux was always mainly contributed by abrupt change in horizontal velocity field on a sunspot located near the flaring polarity inversion line. The velocity field on each sunspot shows either an obvious vortex patten or an shearing patten relative to the another magnetic polarity, which tended to relax the magnetic twist or shear in the corona. During these flares, abrupt change in the Lorentz force acting on these sunspots were found. The rotational motions and shearing motions of these sunspots always had the same directions with the resultant Lorentz forces. These results support the view that the impulsive helicity transportation during the flare could be driven by the change in the Lorentz force applied on the photosphere.

reforms.

description: The world-wide electricity sector reforms of the early 1990s have revealed the complexities of introducing market driven reforms and making them work in network and infrastructure industries. This paper re-flects on the experience to date with the process and outcomes of market-based electricity reforms in less-developed, transition and developed economies. Evidence suggests similar problems facing the electricity sector of these countries though the contexts vary significantly. Many developing and developed economies continue to have investment inadequacy concerns and the need to balance economic efficiency, sustainability and social equity after more than two decades of experience with reforms. We also use case studies of three selected countries that in many respects represent the current state of the reform though they are rarely examined. Nepal, Belarus and Ireland are chosen as country-specific case studies for this purpose. We conclude that the changing dynamics of the electricity supply indus try (ESI) and policy objectives imply that reforms evolve continuously and thus remain work in progress making their success or failure a complex function of micro, macro, and institutional factors.
Robust Differential Received Signal Strength-Based Localization

description: Source localization based on signal strength measurements has become very popular due to its practical simplicity. However, the severe nonlinearity and non-convexity make the related optimization problem mathematically difficult to solve, especially when the transmit power or the path-loss exponent (PLE) is unknown. Moreover, even if the PLE is known but not perfectly estimated or the anchor location information is not accurate, the constructed data model will become uncertain, making the problem again hard to solve. This paper particularly focuses on differential received signal strength (DRSS)-based localization with model uncertainties in case of unknown transmit power and PLE. A new whitened model for DRSS-based localization with unknown transmit powers is first presented and investigated. When assuming the PLE is known, we introduce two estimators based on an exact data model, an advanced best linear unbiased estimator (A-BLUE) and a Lagrangian estimator (LE), and then we present a robust semidefinite programming (SDP)-based estimator (RSDPE), which can cope with model uncertainties (imperfect PLE and inaccurate anchor location information). The three proposed estimators have their own advantages from different perspectives: the A-BLUE has the lowest complexity; the LE holds the best accuracy for a small measurement noise; and the RSDPE yields the best performance under a large measurement noise and possesses a very good robustness against model uncertainties. Finally, we propose a robust SDP-based block coordinate descent estimator (RSDP-BCDE) to deal with a completely unknown PLE and its performance converges to that of the RSDPE using a perfectly known PLE.

description: Unsupervised learning poses one of the most difficult challenges in computer vision today. The task has an immense practical value with many applications in artificial intelligence and emerging technologies, as large quantities of unlabeled videos can be collected at relatively low cost. In this paper, we address the unsupervised learning problem in the context of detecting the main foreground objects in single images. We train a student deep network to predict the output of a teacher pathway that performs unsupervised object discovery in videos or large image collections. Our approach is different from published methods on unsupervised object discovery. We move the unsupervised learning phase during training time, then at test time we apply the standard feed-forward processing along the student pathway. This strategy has the benefit of allowing increased generalization possibilities during training, while remaining fast at testing. Our unsupervised learning algorithm can run over several generations of student-teacher training. Thus, a group of student networks trained in the first generation collectively create the teacher at the next generation. In experiments our method achieves top results on three current datasets for object discovery in video, unsupervised image segmentation and saliency detection. At test time the proposed system is fast, being one to two orders of magnitude faster than published unsupervised methods.

The Palermo herbarium was looted and damaged during the revolutionary uprisings of 1820 (see Coppoler 1828). For this reason, we decided to designate PAL6348 as neotype of the name. It is complete in all its parts, fits the original description and corresponds to the actual use of the name that applies to an accepted species occurring in the mountains of Sicily and Greece. The subspecies nebrodensis is endemic to the Madonie Mountains (Brullo & Brullo 2020).

description: We present a general analysis of the spin transfer for $Λ$ and $\barΛ$ production in deep-inelastic scattering of polarized charged leptons on the nucleon, and find that the pattern of different behaviors of $Λ$ and $\barΛ$ production observed by the E665 Collaboration suggests the possibility of quark-antiquark asymmetries either in the quark to $Λ$ fragmentation functions and/or in the quark and antiquark distributions of the target proton. We also point out that the strange-antistrange asymmetry of the nucleon sea may produce an observable contribution to the different behaviors of $Λ$ and $\barΛ$ production. We find that a softer $\bar{s}(x)$ than $s(x)$ as predicted by the light-cone baryon-meson fluctuation model of intrinsic quark-antiquark pairs of the nucleon sea might lead to a reasonable picture. However, the magnitude is still too small to explain the E665 data and the conclusion has also strong model-dependence. This may suggest the importance of quark-antiquark asymmetry in the quark to $Λ$ fragmentation functions, provided that the E665 data are confirmed.

Missing Women in the United Kingdom

description: This paper investigates the gender-selection decisions of immigrants in the United Kingdom, using data from the 1971-2006 General Household Survey. We examine sex-selective abortion in the UK among immigrant families and the gender composition of previous births, conditional on socio-economic characteristics. Our key result is that immigrants balance their family after the birth of two sons, by having a daughter thereafter. Our study also is the first to estimate the number of missing women among Asian immigrants in a European country, contributing to research on the US and Canada that missing women are also a phenomenon of the developed world.
Measuring Energy Security

description: Continuity of energy supplies is a central aspect of concerns about energy security. Although the continuity of supplies can be influenced by a large number of risks, most models only analyse a small subset of risk sources and often neglect interdependencies between them. In this paper we introduce a probabilistic time-series model that quantifies the impact of inter-dependent natural, technical and human risk sources on energy supply continuity. Based on a case study of Italian gas and electricity markets we conclude that typical simplifications in time-series models and alternative approaches lead to a bias, which justifies the usage of detailed time-series models of interdependent risks such as the framework suggested in this paper, even though more detailed versions of this and other frameworks may quickly become very resource intensive.

Aggregating Elasticities: Intensive and Extensive Margins of Female Labour Supply

description: There is a renewed interest in the size of labour supply elasticities and the discrepancy between micro and macro estimates. Recent contributions have stressed the distinction between changes in labour supply at the extensive and the intensive margin. In this paper, we stress the importance of individual heterogeneity and aggregation problems. At the intensive margins, simple specifications that seem to fit the data give rise to non linear expressions that do not aggregate in a simple fashion. At the extensive margin, aggregate changes in participation are likely to depend on the cross sectional distribution of state variables when a shock hits and, therefore, are likely to be history dependent. We tackle these aggregation issues directly by specifying a life cycle model to explain female labour supply in the US and estimate its various components. We estimate the parameters of different component of the model. Our results indicate that (i) at the intensive margin, Marshallian and Hicksian elasticities are very heterogeneous and, on average, relatively large; (ii) Frisch elasticities are, as implied by the theory, even larger; (iii) aggregate labour supply elasticities seem to vary over the business cycle, being larger during recessions.

 Lectotype (here designated):—[Sicily] Vulpia tenuis Parl., Bromus tenuis Nob., Bromus littoreus Guss., Girgenti spiaggia, Terranova, April, s. c. [manu V. Tineo] (PAL77156!, image available at http://147.163.8.207/zoomify/view_img.asp?ic=77156).
 Note:—We traced on sheet at PAL (code PAL77156) including a single plant, and two handwritten labels by Vincenzo Tineo: one from “Girgenti” [now Agrigento city, S-Sicily] and the other from “Terranova” [now Gela town, S-Sicily] without date. As already done in other contributions (Nardi 1984, Domina & Mazzola 2007, Scafidi & Domina 2019), Tineo’s specimens in PAL, although not reporting the collection date, are presumptively considered original material. PAL77156 was checked by C. A. Stace in November 1980, but it has not been used for nomenclatural acts by this author, as in our knowledge. PAL77156 matches the protologue and corresponds to the current application of the name. This taxon has controversial interpretations. Some authors consider it an independent species (Bartolucci & al. 2018), others a subspecies of Vulpiella stipoides (Valdés & Scholz 2009), still others a synonym of V. stipoides (Stace 2022). The nomenclatural type designation can help specialists clarify its taxonomy.

description: The purpose of this study was to gain a better understanding of music educators’ perceptions of ways in which marching band and college music education curricula connect. By examining the music educators’ perceptions, the study hoped to influence existing collegiate music education programs by providing possible avenues of interdisciplinary development through cross-training experiences of marching band and marching band methods. The guiding research questions for this study were: 1) What are the perceptions of music educators regarding connection between music education curriculum and marching band? 2) Do music educators feel marching band impacted their music teaching careers? 3) What experiences in marching band, if any, do music educators feel helped prepare them to become music educators? This study was designed to survey music educators in private and public institutions within the United States.
OPEC vs US shale oil: Analyzing the shift to a market-share strategy

description: In November 2014, OPEC announced a new strategy geared towards improving its market share. Oil-market analysts interpreted this as an attempt to squeeze higher-cost producers, notably US shale oil, out of the market. Over the next year, crude oil prices crashed, with large repercussions for the global economy. We present a simple equilibrium model that explains the fundamental market factors that can rationalize such a ���regime switch�� by OPEC. These include: (i) the growth of US shale oil production; (ii) the slowdown of global oil demand; (iii) reduced cohesiveness of the OPEC cartel; (iv) production ramp-ups in other non-OPEC countries. We show that these qualitative predictions are broadly consistent with oil market developments during 2014-15. The model is calibrated to oil market data; it predicts accommodation up to 2014 and a market-share strategy thereafter, and explains large oil-price swings as well as realistically high levels of OPEC output.

The Consumption Response to Liquidity-Enhancing Transfers: Evidence from Italian Earthquakes

description: Exploiting three Italian earthquakes as quasi-experiments, we analyze the response of homeowners' consumption to targeted transfers, financing housing reconstruction over time. Like loans, these transfers mainly affect the liquidity of households' wealth in the short run: we show that they have no effect on consumption over a multi-year horizon. Yet, the access to reconstruction funds has significantly heterogeneous effects on impact: it strongly raises non-durable consumption by households with low liquidity and bank debt (the 'wealthy-hand-to-mouth'); it makes no difference for liquid households. Consistently, in either group, consumption is insensitive to transfer funds that accrue directly to firms.
