The Effect of Participative Leadership Style on Employees’ Performance: The Contingent Role of Institutional Theory

This study aimed to examine the moderating role of institutional theory in the association between participative leadership style and various outcomes, such as employee loyalty and job performance in organizations. A cross-sectional research design was employed, where data were gathered from 347 participants from all managerial levels in the United Arab Emirates (UAE). The findings demonstrated how the level of complexity of the institutional theory reduces the positive relationship between participative leadership style and employee loyalty, negatively affecting job performance. The current study contributes to the existing leadership literature by showing that participatory leaders do not behave similarly across various degrees of institutional theory complexity. The findings suggest that the higher the complexity of institutionalism, the wider the gap between leaders and subordinates, so implementing the participative style may become problematic in some circumstances.
A LOW-AMPLITUDE PERIODICITY IN THE RADIAL VELOCITY AND CHROMOSPHERIC EMISSION OF BETA GEMINORUM

Using high-quality spectra obtained with the hydrogren fluoride technique at the Canada-France-Hawaii 3.6-meter telescope and Dominion Astrophysical Observatory 1.22-meter telescope, we have detected a low-amplitude periodicity in both the radial velocity and chromospheric emission of Beta Geminorum. In addition, we have detected a long-term change (time scale > 12 years) in thi star's chromospheric emission which is reminiscent of solar-type magnetic cycles believed present in giants of similar spectral type. The radial-velocity variations can be fitted by a sinusoid with amplitude and period of K = 46.23 ± 3.9 m s-1, P=584.65 ± 3.3 days. A similar, statistically significant (false-alarm probability of 1%) period is found in the residuals from the long-term trend in the chromospheric emission: P = 587.7 ± 12 days. However, because of the weakness of the signal, K = 0.583 ± 19 mA, this detection needs confirmation. Although these independently determined periods are in agreement with each other, they are not consistent with the maximum rotation period of 178 days derived from this star's v sin i = 2.5 km s-1 (Gray 1982). Either the observed v sin i value of Beta Geminorum needs to be revised below 0.76 km s-1 or some alternative to rotational modulation of surface phenomena must be found to explain this star's periodicity.
Heterodyne laser Doppler distance sensor with phase coding measuring stationary as well as laterally and axially moving objects

Both in production engineering and process control, multidirectional displacements, deformations and vibrations of moving or rotating components have to be measured dynamically, contactlessly and with high precision. Optical sensors would be predestined for this task, but their measurement rate is often fundamentally limited. Furthermore, almost all conventional sensors measure only one measurand, i.e. either out-of-plane or in-plane distance or velocity. To solve this problem, we present a novel phase coded heterodyne laser Doppler distance sensor (PH-LDDS), which is able to determine out-of-plane (axial) position and in-plane (lateral) velocity of rough solid-state objects simultaneously and independently with a single sensor. Due to the applied heterodyne technique, stationary or purely axially moving objects can also be measured. In addition, it is shown theoretically as well as experimentally that this sensor offers concurrently high temporal resolution and high position resolution since its position uncertainty is in principle independent of the lateral object velocity in contrast to conventional distance sensors. This is a unique feature of the PH-LDDS enabling precise and dynamic position and shape measurements also of fast moving objects. With an optimized sensor setup, an average position resolution of 240 nm was obtained.

A Numerical Study on Appearance of the Runaway Greenhouse State of a Three-Dimensional Gray Atmosphere

Abstract A numerical study on the runaway greenhouse state is performed by using a general circulation model (GCM) with simplified hydrologic and radiative processes. Except for the inclusion of three-dimensional atmospheric motion, the system utilized is basically equivalent to the one-dimensional radiative–convective equilibrium model of Nakajima et al. in which the runaway greenhouse state is defined. The results of integrations with various values of solar constant show that there exists an upper limit of the solar constant with which the atmosphere can reach a statistical equilibrium state. When the value of solar constant exceeds the limit, 1600 W m−2, the atmosphere sets in a “thermally runaway” state. It is characterized by continuous increase of the amount of water vapor, continuous decrease of the outgoing longwave radiation, and continuous warming of the atmosphere and the ground surface. The upper-limit value of the solar constant obtained by the GCM experiments corresponds to the upper limit .
Prospective time periodic geographical disease surveillance using a scan statistic

Most disease registries are updated at least yearly. If a geographically localized health hazard suddenly occurs, we would like to have a surveillance system in place that can pick up a new geographical disease cluster as quickly as possible, irrespective of its location and size. At the same time, we want to minimize the number of false alarms. By using a space–time scan statistic, we propose and illustrate a system for regular time periodic disease surveillance to detect any currently ‘active’ geographical clusters of disease and which tests the statistical significance of such clusters adjusting for the multitude of possible geographical locations and sizes, time intervals and time periodic analyses. The method is illustrated on thyroid cancer among men in New Mexico 1973–1992.
Training Load Monitoring Practices Used by Strength and Conditioning Coaches in Hurling, Gaelic Football, Camogie, and Ladies Gaelic Football

Background: No research has investigated the training load (TL) monitoring practices currently used by strength and conditioning (S&C) coaches in Gaelic games. The purpose of this study was to investigate the TL monitoring practices used by S&C coaches across senior intercounty male and female Gaelic game sports. Study Design: Cross-sectional. Hypotheses: It was hypothesized that (1) TL is commonly monitored, (2) various methods are used by S&C coaches to monitor TL, and (3) the level of qualifications of the S&C coach is of a professional standard. Level of Evidence: Level 4. Methods: A total of 33 (n = 32 male and n = 1 female) S&C coaches participated in the study by completing an online questionnaire that investigated coach biography, coach education, team biography, monitoring practices, rating of perceived exertion, acute:chronic workload ratio, and data implementation. Results: The results showed that S&C coaches had varying levels of experience and education. All 33 coaches (100%) stated they monitored the TL of the players. The most common method used to monitor TL was session rating of perceived exertion, which was used by 91% of coaches. Analysis of an open-ended question afforded each participant the opportunity to share additional information, highlighting 3 themes: (1) communication with players, (2) performance testing, and (3) clarity and support among other coaching staff. Conclusion: Multiple methods are used to monitor TL in Gaelic games. Despite multiple forms of technology available, communication with players provides essential information regarding an athlete’s state. Clinical Relevance: As this is the first study to explore TL monitoring practices used by S&C coaches in Gaelic games, the results may inform the development of educational resources for the guidance of coaches working in Gaelic games in best practice TL monitoring.
A class of semi-Lagrangian approximations for fluids.

Abstract This paper discusses a class of finite-difference approximations to the evolution equations of fluid dynamics. These approximations derive from elementary properties of differential forms. Values of a fluid variable ψ at any two points of a space-time continuum are related through the integral of the space-time gradient of ψ along an arbitrary contour connecting these two points (Stokes' theorem). Noting that spatial and temporal components of the gradient are related through the fluid equations, and selecting the contour composed of a parcel trajectory and an appropriate residual, leads to the integral form of the fluid equations, which is particularly convenient for finite-difference approximations. In these equations, the inertial and forcing terms are separated such that forces are integrated along a parcel trajectory (the Lagrangian aspect), whereas advection of the variable is evaluated along the residual contour (the Eulerian aspect). The virtue of this method is an extreme simplicity of t.
Efficacy of guideline‐directed medical treatment in heart failure with mildly reduced ejection fraction

Heart failure with mildly reduced ejection fraction (HFmrEF) has received increasing attention following the publication of the latest ESC guidelines in 2021. However, it remains unclear whether patients with HFmrEF could benefit from guideline‐directed medical treatment (GDMT), referring the combination of ACEI/ARB/ARNI, β‐blockers, and MRAs, which are recommended for those with reduced ejection fraction. This study explored the efficacy of GDMT in HFmrEF patients.

Simulation and Prediction of the Catalina Eddy

Abstract Observational studies generally suggest that the formation of the Catalina Eddy in the bight of southern California results from interaction between the synoptic-scale northerly flow and the topographic barrier along the southern California coast. In an attempt to better understand the eddy generation mechanisms, a high-resolution mesoscale model is initialized and forced on the lateral boundaries by NMC's large-scale objective analysis, and a detailed numerical study of the 26–30 June 1988 Catalina Eddy event is presented. The model results compare favorably with the observations and generally support the aforementioned mechanism of the eddy formation. It appears that a warm air mass over the bight resulting from adiabatic heating of low-level downslope flow deflected by the mountain barrier significantly helps create the alongshore and offshore pressure gradients favorable for the generation of a cyclonic vorticity. Although current operational forecast models are capable of often accurately pr.
Volume electron microscopy reveals age-related circuit remodeling in the auditory brainstem

The medial nucleus of the trapezoid body (MNTB) is an integral component of the auditory brainstem circuitry involved in sound localization. The giant presynaptic nerve terminal with multiple active zones, the calyx of Held (CH), is a hallmark of this nucleus, which mediates fast and synchronized glutamatergic synaptic transmission. To delineate how these synaptic structures adapt to reduced auditory afferents due to aging, we acquired and reconstructed circuitry-level volumes of mouse MNTB at different ages (3 weeks, 6, 18, and 24 months) using serial block-face electron microscopy. We used C57BL/6J, the most widely inbred mouse strain used for transgenic lines, which displays a type of age-related hearing loss. We found that MNTB neurons reduce in density with age. Surprisingly we observed an average of approximately 10% of poly-innervated MNTB neurons along the mouse lifespan, with prevalence in the low frequency region. Moreover, a tonotopy-dependent heterogeneity in CH morphology was observed in young but not in older mice. In conclusion, our data support the notion that age-related hearing impairments can be in part a direct consequence of several structural alterations and circuit remodeling in the brainstem.
Solar microbursts at meter-decameter wavelengths

Microbursts are low-brightness temperature bursts observed by the Clark Lake radioheliograph. The bursts occur several times per hour during quiet Sun periods and are seen at the observing frequencies from 30 to 70 MHz. They are stationary at a given frequency, have short rise times, and durations of 2-10 s. Observations of the bursts are presented and given an interpretation in terms of plasma emmission. The burst properties suggest that they are weak type III bursts. The observations imply that energy releases on the Sun continue to be impulsive, with nonthermal electron distributions, for small releases of energy. The relation of the bursts to type III bursts and hard X-ray bursts are discussed.
The Use of the Buddy Balloon Technique in Transcatheter Aortic Valve Replacement Procedure

Transcatheter aortic valve replacement (TAVR) is a new, rapidly evolving technology used in severe cases of aortic stenosis. Some TAVR procedures have failed to deliver the prosthetic valve due to challenges. In these cases, it is difficult to pass a bulky prosthesis through a narrowed and calcified aortic valve. Special techniques may be needed in these challenging cases. In our case, the extreme calcification and the horizontal aorta caused the delivery system to hang up on the aortic valve. We used a buddy balloon from the contralateral femoral artery to assist in crossing the native aortic valve.
Double Excited High‐n Spin Dependent Atomic Structure Scaling Laws for He I: Application to Radiative Properties for Edge Plasma Conditions

We present our numerical calculations of dielectronic recombination rate coefficients which are spin dependent (2lnl ′ ‐1snl 1L, 1snl 3L ) and develop scaling relations which are converging for all spin (S), angular (L) and main (n) quantum numbers. The influence of atomic data inaccuracies, spin dependent channelling of dielectronic recombination rates and collisions on the atomic/ionic fractions is discussed.

Comparing Different Estimators in a Nonlinear Measurement Error Model

A nonlinear structural errors-in-variables model is investigated, where the response variable has a density belonging to an exponential family and the error-prone covariate follows a Gaussian distribution. Assuming the error variance to be known, we consider two consistent estimators in addition to the naive estimator. We compare their relative efficiencies by means of their asymptotic covariance matrices for small error variances. The structural quasi score (SQS) estimator is based on a quasi score function, which is constructed from a conditional mean-variance model. Consistency and asymptotic normality of this estimator is proved. The corrected score (CS) estimator is based on an error-corrected likelihood score function. For small error variances the SQS and CS estimators are approximately equally efficient. The polynomial model and the Poisson regression model are explored in greater detail.
Antioxidants in Shell and Nut Yield Components after Ca, Mg and K Preharvest Spraying on Hazelnut Plantations in Southern Chile

To determine the effects of pre-harvest calcium (Ca), magnesium (Mg) and potassium (K) spraying on the antioxidant activity and capacity of hazelnut (Corylus avellana L.) shells, as an approach to sustain the utilization of the main residue derived from this industry, four commercial hazelnut (Tonda di Giffoni) orchards located in Southern Chile (Cunco, Gorbea, Perquenco and Radal), during the 2018/19 season were sprayed three times with five combinations of Ca (300 and 600 mg L−1), Mg (300 and 600 mg L−1) and K (300 and 600 mg L−1). Yield components were determined in harvested whole nuts, whereas Ca, Mg and K concentrations, as well as total phenolic compounds, free radical scavenging antioxidant activity, and oxygen radical absorbance capacity, were determined in shells. All spray treatments with both Ca, Mg and K combinations showed a significant interaction between locality and treatment (L × T) on increased stabilized nut yield (kg ha−1) in comparison with the control treatments, whereas nut quality was differentially affected by treatment and orchard locality, thus confirming a significant L × T relationship regarding nut length and kernel yield. However, locality showed a major effect on kernels and shells. A significant relationship was determined between locality and the Ca, Mg and K spraying (L × T) concerning antioxidant compounds such as phenolics, whose amounts exceeded those of the control treatments by three times. Antioxidant capacity and activity in shells showed a significant L × T relationship, and nutshells collected from Cunco showed remarkably (3–4 times) higher levels of these factors than the other evaluated localities. Interactions between spray treatment and orchard location were responsible for the different values obtained in the experiments, confirming the influence of the environment on the efficacy of the treatments. Finally, these shells are worth further study as an interesting residue of the hazelnut industry due to their nutritional and antioxidant properties.
Boosting Students’ Speaking skill using Ted Talks YouTube Videos: Teacher Talk Theory

Even though the importance of teaching English speaking using TED Talks to improve students’ speaking skill has been acknowledged, however, far too little attention has been paid to investigate students’ perceptions on the use of TED Talks dealing with teacher talk categories such as dealing with feelings, praising and encouraging, making joke, as well as giving direction and lecturing. This study aimed to investigate the concordance of the students’ speech ability development and the students’ interest and motivation towards the use of TED Talks to boost the students’ speaking skill. This present used both quantitative and qualitative design. The samples of the students were 27 students from grade 7E in MTsN Surabaya. For the quantitative data, the data was collected using pre-test and post-test. However, for the qualitative data, the data was gathered using interview protocol. The data was analyzed using descriptive analysis. The findings of this study found that the students improve their English speaking skill especially the pronunciation and the fluency of delivering English speech in front of their friends after the treatment using the TED Talks videos. Regarding the students’ perceptions of the use TED Talks to support teacher talks, most of the students agreed that TED Talks videos can support teacher talks related to the category of dealing with feelings, praising and encouraging, making jokes and giving direction as well as lecturing.
Refinement of the spectral asymptotics of generalized Krein Feller operators

Abstract Spectral asymptotics of operators of the form are investigated. In the case of self-similar measures μ and ν it turns out that the eigenvalue counting function N(x) under both Dirichlet and Neumann conditions behaves like xγ as x → ∞, where the spectral exponent γ is given in terms of the scaling numbers of the measures. More precisely, it holds that In the present paper, we give a refinement of this spectral result, i.e. we give a sufficient condition under which the term N(x)x –γ converges. We show, using renewal theory, that the behaviour of N(x)x –γ depends essentially on whether the set of logarithms of the scaling numbers of the measures is arithmetic.
Semilinear hyperbolic systems with blowup at infinity

We investigate semilinear hyperbolic systems in three-space dimensions with quadratic terms in gradient of the solution, not satisfying the null condition. Under some algebraic conditions ensuring global existence for solutions of the reduced systems (the so-called weak null condition of Lindblad and Rodnianski), we prove global existence of classical solutions for these systems.
Two theorems on boundary values of analytic functions

We shall be concerned with the boundary behaviour of analytic functions in a smooth bounded domain in Cn. For background and motivation, the reader is referred to Chapter I of the book by Stein [3]. The aim of this paper is to present two new results, as a corollary of which we shall be able to give very quick and simple proofs of the results in [3, Chapter 2]. T1he author would very much like to express thanks to his adviser Dr. D. A. Edwards for encouragement, to Professor E. M. Stein for pointing out some ambiguity in the proof of Theorem 2 in the original manuscript, and to Mrs. V. Shires for performing the typing. Recall the definition [3, p. 32] of the admissible approach regions 6a (() at E eaD: a) (o= {Z E D: I(Z 0vt < (I + a) 8(Z), IZ 12 < ad (Z)), S((Z) = min(dist of Z from aD, dist of Z from tangent plane at ), vi = outward drawn normal at (. The regions da (C) have conical sections in the direction of the "classical tangent" {iv), but "tangential parabolic" sections in the 2n 2 complementary real directions (which are n I complex directions, of course). Recall also the two types of ball on aD [3, p. 33]. T1he balls B1 are the usual ones of radius p centered at ( E aD, and the balls B2 are of radius p in the classical direction, but of radius -p"/2 in the complex directions. We consider also the corresponding maximal functions, denoted * and 2.
Major Causes of Variation of External Appearance, Chemical Composition, Texture, and Color Traits of 37 Categories of Cheeses

Cheeses are produced by many different procedures, giving rise to many types differing in ripening time, size, shape, chemical composition, color, texture, and sensory properties. As the first step in a large project, our aim was to characterize and quantify the major sources of variation in cheese characteristics by sampling 1050 different cheeses manufactured by over 100 producers and grouped into 37 categories (16 with protected designation of origin, 4 traditional cheese categories, 3 pasta filata cheese categories, 5 flavored cheese categories, 2 goat milk categories, and 7 other categories ranging from very fresh to very hard cheeses). We obtained 17 traits from each cheese (shape, height, diameter, weight, moisture, fat, protein, water soluble nitrogen, ash, pH, 5 color traits, firmness, and adhesiveness). The main groups of cheese categories were characterized and are discussed in terms of the effects of the prevalent area of origin/feeding system, species of lactating females, main cheese-making technologies, and additives used. The results will allow us to proceed with the further steps, which will address the interrelationships among the different traits characterizing cheeses, detailed analyses of the nutrients affecting human health and sensorial fingerprinting.
