Career Development System of Village Secretary after Becoming Civil Apertures (A Case Study in North Aceh District)

ARTICLE INFO ABSTRACT Article History Received: March 21, 2020 Accepted: April 92, 2020 Volume: 2 Issue: 3 This study aimed at understanding and describing the career development system of the village secretary and its obstacles after appointing to be a civil servant. The research method used was descriptive qualitative research type, with data acquisition procedures carried out through interviews, observation, and documentation. Data analysis techniques adopted through data collection, data reduction, data presentation, and data verification. This study uses 10 key informants determined based on purposive sampling consisting of the North Aceh stakeholders who have been appointed as the state civil apparatus. The results of the study found that the career development system of the village secretary as a state civil apparatus is implemented through a merger of the career system and the achievement system. The career system considers more the principles of seniority, age, tenure, rank and work experience. While the achievement system prioritizes the principles of professionalism, competence, level of education, education and training programs that have been attended, knowledge, abilities, and skills possessed enthusiasm and enthusiasm for work, work behavior and culture. Furthermore, the results of the study showed that the obstacles in increasing the career of the village secretary as a state civil apparatus were low education, lack of awareness and knowledge, low motivation, and lack of opportunities to participate in training in order to increase knowledge, skills, skills, and abilities to realize maximum apparatus performance improvement.

THE ASSOCIATION BETWEEN BULLYING, MALTREATMENT, AND PERSONALITY TRAITS AMONG ADOLESCENTS FROM ARMENIAN SCHOOLS IN LEBANON

The aim of this study was to identify the association between bullying, child domestic maltreatment, and personality traits among adolescents within a group of Armenian schools in Lebanon. Participants were 185 students in grades 7 to 10, attending Armenian schools in Beirut and its suburbs. The study depended on the self-report method, where participants supplied demographic information and filled in three questionnaires: Illinois Bully Scale, International Child Abuse Screening Tool – Children’s Version (ICAST – CH) and Personality Inventory for DSM-5 Brief Form (PID-5-BF) Child Age 11 – 17. Results, calculated by using ANOVA and Pearson correlation, indicated a statistically significant difference at the level of physical abuse between “victim” and “control” groups. Also, there were significant correlations between the “antagonistic” and “disinhibition” maladaptive personality traits and being a bully. The outcome of this study indicated the necessity of promoting parental and school guidance for preventing physical abuse within school, as well as concentrating on identifying the bully personality implicated in antagonism and disinhibition maladaptive personality traits within adolescents attending Armenian schools in Lebanon. The study includes prevalence information on bullies and victims in these schools, gender differences among bullies and victims, and clinical and research implications.
Évolution du potentiel hydrique et du système racinaire de jeunes plants de cèdre, pin laricio de Corse et pin noir plantés à l'automne et au printemps

Les auteurs ont suivi, apres plantations a racines nues en automne et au printemps, l'evolution du potentiel hydrique de base et l'etat de regeneration du systeme racinaire de plants de cedre, de pin laricio de Corse et de pin noir d'Autriche. Deux traitements ont ete consideres: traitement I (temoin): les plants ont conserve leurs extremites racinaires blanches, traitement II: toutes les racines blanches ont ete excisees. Les observations effectuees montrent que quel que soit le traitement, les plants pourvus de racines blanches au moment de la mesure, ont un potentiel hydrique de base significativement plus eleve que ceux qui en sont depourvus. Lorsque le potentiel de base etait inferieur a −1,5 MPa, les plants ne presentaient pas de racines blanches. L'etude de la repartition des plants, par classe de potentiel hydrique, montre que le pin laricio de Corse, contrairement aux deux autres especes, a des difficultes a maintenir un etat hydrique eleve malgre une plantation preservant les extremites racinaires.
Fluctuations of topological charge and chiral density in the early stage of high energy nuclear collisions

We study systematically the topological charge density and the chiral density correlations in the early stage of high energy nuclear collisions: the intial condition is given by the McLerran-Venugopalan model and the evolution of the gluon fields is studied via the Classical Yang-Mills equations up to proper time $\tau\approx 1$ fm/c for an $SU(2)$ evolving Glasma. Topological charge is related to the gauge invariant $\bm E \cdot \bm B$ where $\bm E$ and $\bm B$ denote the color-electric and color-magnetic fields, while the chiral density is produced via the chiral anomaly of Quantum Chromodynamics. We study how the correlation lengths are related to the collision energy, and how the correlated domains grow up with proper time in the transverse plane for a boost invariant longitudinal expansion. We estimate the correlation lengths of both quantities, that after a short transient results of the order of the typical energy scale of the model, namely the inverse of the saturation scale. We estimate the proper time for the formation of a steady state in which the production of the chiral density in the transverse plane per unit rapidity slows down, as well as the amount of chiral density that would be present at the switch time between the Classical Yang-Mills evolution and the relativistic transport or hydro for the quark-gluon plasma phase.
C-Vectors and Non-Self-Crossing Curves for Acyclic Quivers of Finite Type

Let $Q$ be an acyclic quiver and $k$ be an algebraically closed field. The indecomposable exceptional modules of the path algebra $kQ$ have been widely studied. The real Schur roots of the root system associated to $Q$ are the dimension vectors of the indecomposable exceptional modules. It has been shown in \cite{c} that for acyclic quivers, the set of positive $c$-vectors and the set of real Schur roots coincide. To give a diagrammatic description of $c$-vectors, K-H. Lee and K. Lee conjectured that for acyclic quivers, the set of c-vectors and the set of roots corresponding to non-self-crossing admissible curves are equivalent as sets in \cite{ll}. In \cite{ft}, A. Felikson and P. Tumarkin proved this conjecture for 2-complete quivers. In this paper, we prove a revised version of Lee-Lee conjecture for acyclic quivers of type $A$, $D$, and $E_{6}$ and $E_7$.
Poisson-Nijenhuis Structure on Lie groupoids from the Invariance's Point of View

In this paper, we introduce right-invariant (similarly, left-invariant) Poisson-Nijenhuis Structures on Lie groupoids and their infinitesimal counterparts as called $(\Lambda , \mathbf{n})-$structures. We present a mutual correspondence between $(\Lambda ,\mathbf{n})-$structures on Lie algebroids with Poisson-Nijenhuis structures $(\Pi , \mathbf{N})$ on their Lie groupoids under some conditions. Also, we will construct Poisson-Nijenhuis pair groupoids as an example from the invariance's point of view.
Modified cosmology through spacetime thermodynamics and Barrow horizon entropy

We present modified cosmological scenarios that arise from the application of the “gravity-thermodynamics” conjecture, using the Barrow entropy instead of the usual Bekenstein-Hawking one. The former is a modification of the black hole entropy due to quantum-gravitational effects that deform the black-hole horizon by giving it an intricate, fractal structure. We extract modified cosmological equations which contain new extra terms that constitute an effective dark-energy sector, and which coincide with the usual Friedmann equations in the case where the new Barrow exponent acquires its Bekenstein-Hawking value. We present analytical expressions for the evolution of the effective dark energy density parameter, and we show that the universe undergoes through the usual matter and dark-energy epochs. Additionally, the dark-energy equation-of-state parameter is affected by the value of the Barrow deformation exponent and it can lie in the quintessence or phantom regime, or experience the phantom-divide crossing. Finally, at asymptotically large times the universe always results in the de-Sitter solution.
CONDITIONAL LOGIC IS COMPLETE FOR CONVEXITY IN THE PLANE

Abstract We prove completeness of preferential conditional logic with respect to convexity over finite sets of points in the Euclidean plane. A conditional is defined to be true in a finite set of points if all extreme points of the set interpreting the antecedent satisfy the consequent. Equivalently, a conditional is true if the antecedent is contained in the convex hull of the points that satisfy both the antecedent and consequent. Our result is then that every consistent formula without nested conditionals is satisfiable in a model based on a finite set of points in the plane. The proof relies on a result by Richter and Rogers showing that every finite abstract convex geometry can be represented by convex polygons in the plane.
Stabilized explicit multirate methods for stiff differential equations

Stabilized Runge-Kutta (aka Chebyshev) methods are especially efficient for the numerical solution of large systems of stiff differential equations because they are fully explicit; hence, they are inherently parallel and easily accommodate nonlinearity. For semi-discrete parabolic (or diffusion dominated) problems, for instance, stabilized Runge-Kutta methods overcome the stringent stability condition of standard methods without sacrificing explicitness. However, when much of the stiffness is only induced by a few components, as in the presence of spatially local mesh refinement, their efficiency deteriorates. To remove the crippling effect of a few severely stiff components on the entire system of differential equations, we derive a modified equation, whose stiffness solely depend on the remaining mildly stiff components. By applying stabilized Runge-Kutta methods to this modified equation, we then devise an explicit multirate Runge-Kutta-Chebyshev (mRKC) method whose stability conditions are independent of a few severely stiff components. Stability of the mRKC method is proved for a model problem, whereas its efficiency and usefulness are demonstrated through a series of numerical experiments.
THE TERMINOLOGY OF FEMALE POLYMORPHS OF ISCHNURA (ZYGOPTERA: COENAGRIONIDAE)

This paper is dedicated to Philip S. Corbet on the occasion of his 70th birthday. Abstract It is suggested that the current range of terminology employed to name the polymorphs of Ischnura elegans (Vander Linden) should be simplified and standardised in order to avoid confusion. It is proposed that the adult female forms be known as andromorph, infuscans and rufescens-obsoleta.
The evolution of traveling waves in a KPP reaction–diffusion model with cut‐off reaction rate. II. Evolution of traveling waves

In Part II of this series of papers, we consider an initial‐boundary value problem for the Kolmogorov–Petrovskii–Piscounov (KPP)‐type equation with a discontinuous cut‐off in the reaction function at concentration u=uc . For fixed cut‐off value uc∈(0,1) , we apply the method of matched asymptotic coordinate expansions to obtain the complete large‐time asymptotic form of the solution, which exhibits the formation of a permanent form traveling wave (PTW) structure. In particular, this approach allows the correction to the wave speed and the rate of convergence of the solution onto the PTW to be determined via a detailed analysis of the asymptotic structures in small time and, subsequently, in large space. The asymptotic results are confirmed against numerical results obtained for the particular case of a cut‐off Fisher reaction function.
Relative critical loci and quiver moduli

In this paper we identify the cotangent to the derived stack of representations of a quiver $Q$ with the derived moduli stack of modules over the Ginzburg dg-algebra associated with $Q$. More generally, we extend this result to finite type dg-categories, to a relative setting as well, and to deformations of these. It allows us to recover and generalize some results of Yeung, and leads us to the discovery of seemingly new lagrangian subvarieties in the Hilbert scheme of points in the plane.
Generalizing Random Fourier Features via Generalized Measures

We generalize random Fourier features, that usually require kernel functions to be both stationary and positive definite (PD), to a more general range of non-stationary or/and non-PD kernels, e.g., dot-product kernels on the unit sphere and a linear combination of positive definite kernels. Specifically, we find that the popular neural tangent kernel in two-layer ReLU network, a typical dot-product kernel, is shift-invariant but not positive definite if we consider $\ell_2$-normalized data. By introducing the signed measure, we propose a general framework that covers the above kernels by associating them with specific finite Borel measures, i.e., probability distributions. In this manner, we are able to provide the first random features algorithm to obtain unbiased estimation of these kernels. Experiments on several benchmark datasets verify the effectiveness of our algorithm over the existing methods. Last but not least, our work provides a sufficient and necessary condition, which is also computationally implementable, to solve a long-lasting open question: does any indefinite kernel have a positive decomposition?
An FPGA Acceleration and Optimization Techniques for 2D LiDAR SLAM Algorithm

An efficient hardware design of Simultaneous Localization and Mapping (SLAM) methods is of necessity for mobile autonomous robots with limited computational resources. In this paper, we develop a resource-efficient FPGA design for accelerating the scan matching process, which typically exhibits the bottleneck in 2D LiDAR SLAM methods. Scan matching is a process of correcting a robot pose by aligning the latest LiDAR measurements with an occupancy grid map, which encodes the information about the surrounding environment. The proposed design exploits an inherent parallelism in the Rao-Blackwellized Particle Filter (RBPF) based algorithms to perform scan matching computations for multiple particles in parallel. In the design, map compression technique and lookup-table are employed to reduce the resource utilization and achieve the maximum throughput. Simulation results using the benchmark datasets show that the scan matching is accelerated by 23.3-51.1x and the overall throughput is improved by 1.97-3.16x without seriously degrading the quality of the final outputs. Furthermore, our implementation requires only 37% of the total resources available in the Xilinx ZCU104 evaluation board, thus providing a feasible solution to realize SLAM applications on indoor mobile robots.
The Thermal Equilibrium Mass-loss Model and Its Applications in Binary Evolution

Binary evolution is indispensable in stellar evolution to understand the formation and evolution of most peculiar and energetic objects, such as binary compact objects, Type Ia supernovae, X-ray binaries, cataclysmic variables, blue stragglers, hot subdwarfs, and central binaries in planetary nebulae. Mass transfer in binary stars can change the evolutionary path and fate of the components compared to what is expected from single stellar evolution. The critical mass ratio at which unstable mass transfer occurs is an unsolved fundamental problem in binary evolution. To resolve this issue, we construct the thermal equilibrium mass-loss model and derive critical mass ratios for both thermal-timescale mass transfer and unstable mass transfer, the latter of which occurs when the outer Lagrangian point, L2, is overfilled. Using several 3.2 M⊙ stellar models as examples, we study the stellar response to thermal equilibrium mass loss and present the thresholds for thermal-timescale mass transfer. We study the possible mass-transfer channels of binary systems containing a 3.2 M⊙ donor star, taking into account thermal-timescale mass transfer, unstable mass transfer through L2, and dynamical-timescale mass transfer. We repeat this simulation for a grid of donor stars with different masses (from 0.1 to 100 M⊙ with Z = 0.02) and at different evolutionary stages, and present our results. The results show that unstable mass transfer due to the overfilling of the outer Lagrangian point may also play an essential role in the formation of common envelopes for late red giant branch and asymptotic giant branch donors.
Summer Movements of Sub-Adult Brook Trout, Landlocked Atlantic Salmon, and Smallmouth Bass in the Rapid River, Maine

ABSTRACT Summer movement patterns and spatial overlap of native sub-adult brook trout (Salvelinus fontinalis), non-native landlocked Atlantic salmon (Salmo salar), and non-native smallmouth bass (Micropterus dolomieu) in the Rapid River, Maine, were investigated with radio telemetry in 2005. Fishes were captured by angling, surgically implanted with radio transmitters, and tracked actively from June through September. Most brook trout (96%) and landlocked salmon (72%) displayed long distance movements (>1 km) to open water bodies (28 June to 4 July) followed by periods of time spent in presumed thermal refigia (5 July to 16 September). Summer water temperature rose above 25 °C, near the reported lethal limits for these coldwater species. In contrast, the majority of smallmouth bass (68%), a warrnwater species, did not make long distance movements from areas of initial capture, remaining in mainstem sections of the river (28 June to 16 September). Spatial overlap of smallmouth bass and brook trout in the summer is unlikely because brook trout presumably move to thermal rehgia during this time. However, interspecific competition between brook trout and landlocked salmon may occur since they select similar habitats June through September.
Foraging Benefits in a Colour Polymorphic Neotropical Orb Web Spider

Conspicuous body colouration in sedentary predators such as orb web spiders seems paradoxical as potential prey can see and avoid the webs. Several studies have demonstrated that rather than deterring prey, the colours act as sensory traps for flower-seeking insects. In chromatically polymorphic species, the existence of more than one colour morph may lead to differing levels of prey attraction. To explore these issues, we studied a neotropical orb web spider, Verrucosa arenata, which shows colour polymorphism with predominantly white or yellow abdomen colours. We asked whether a particular morph is dominant in the population, and whether a particular morph is associated with enhanced foraging success and body condition. Here we showed that although yellow morphs attracted more prey, white morphs were in better body condition. We showed that model prey such as honeybees are able to discriminate between the morphs. We discuss these findings in relation to the functional significance of bright body colouration and colour polymorphism in spiders.
Similarity-and-Independence-Aware Beamformer: Method for Target Source Extraction using Magnitude Spectrogram as Reference

This study presents a novel method for source extraction, referred to as the similarity-and-independence-aware beamformer (SIBF). The SIBF extracts the target signal using a rough magnitude spectrogram as the reference signal. The advantage of the SIBF is that it can obtain an accurate target signal, compared to the spectrogram generated by target-enhancing methods such as the speech enhancement based on deep neural networks (DNNs). For the extraction, we extend the framework of the deflationary independent component analysis, by considering the similarity between the reference and extracted target, as well as the mutual independence of all potential sources. To solve the extraction problem by maximum-likelihood estimation, we introduce two source model types that can reflect the similarity. The experimental results from the CHiME3 dataset show that the target signal extracted by the SIBF is more accurate than the reference signal generated by the DNN.

Colony Defense Strategies of the Honeybees in Thailand

The colony defense strategies of the three honeybee species in Thailand were studied to examine the influence of predation on tropical honeybee societies. Each species focuses its defenses upon different stages in the predation sequence of detection—approach—consumption. This radiation in defense strategies apparently reflects each species' preadaptation by worker size (small, medium—sized, or large) and nest site (cavity or tree branch) to a different pattern of colony defense. Wasps, birds, and primates probably have difficulty finding the small, dispersed colonies of Apis florea, whose nests are built low on the branches of dense, shrubby vegetation. Once found, however, they are easily approached and overpowered because their low, exposed nests are accessible and their small workers inflict relatively painless stings. When overwhelmed, the bees quickly abandon their nest; later, they return to salvage wax. Ants find A. florea nests easily and at least one species (Oecophylla smaragdina) easily kills these small bees. However, sticky bands of resin encircling the nests' slender substrate branches prevent ants from invading A. florea nests. Cavity—nesting colonies of Apis cerana are conspicuous with their medium—sized bees streaming in and out of low, clearly visible entrance holes in caves and hollow tress. However, gaining access to A. cerana nests is difficult. Large predators cannot pass through the small entrance opening and small predators are overpowered by entrance guards. But if a large predator can breach a nest cavity's walls, it faces an only moderately powerful stinging defense. Apis cerana colonies are relatively small and their workers are not fiercely aggressive. Predators easily find the large, sometimes aggregated colonies of Apis dorsata, whose nests hang in the crowns of the tallest forest trees. But only skilled fliers and climbers can reach these lofty nests. Those which do face massive stinging attacks from the large colonies of these relatively giant, ferocious bees. Nests of both open—nesting species, Apis florea and A. dorsata, are protected by a three— to six—layer curtain of bees over the comb. Apis cerana colonies lack these curtains but are protected by their nest cavity walls. A curtain of inactive guards requires a large labor force. The high worker: brood ratio in A. florea relative to A. cerana colonies suggests that the age polyethism schedules of the open— and cavity—nesting species are tuned differently to generate the appropriate proportions of guard bees. Each species' colony defense system consists of numerous interwoven lines of adaptation, including nest site, nest architecture, colony population, labor allocation to defense, age polyethism schedule, colony mobility, and worker morphology, physiology, and behavior. Predation has been a pervasive and powerful force in the evolution of these tropical bee societies.
