Published: February 2023

Denai Lama tourist village is the first tourist village in Deli Serdang Regency. This tourist village was formed by involving the local village government and stakeholders to build a new tourism image in Deli Serdang Regency. The Denai Lama tourist village started on January 20, 2019 but before it was inaugurated there were already tourists visiting there. From the results of the research carried out there were 3 important information, including community responses, namely From the number of families in the village of Denai Lama as many as 921 families who have agricultural land as many as 601 families or 65.25 percent and those who do not have agricultural land 320 families or 34.74 percent who own agricultural land. The community believes that good agricultural products sold before and after being processed really help their economy, especially after the Denai Lama village was officially appointed as a tourist village in April 2022 by the Regent of Deli Serdang. The response of the local government is that currently there are more than 97 families managing small and medium enterprises (MSMEs) and 68% of the community as farmers. From the results they have they are greatly helped because the community is able to process the results of ready-to-eat food products and souvenirs for tourists visiting the tourist village of Denai Lama. The response of tourists is that tourists who visit are very interested in visiting the Denai Lama tourist village because they can enjoy the village atmosphere directly and can enjoy the arts and cultural performances provided and can also enjoy processed products from the available community. The tourist attractions provided are quite entertaining with clean huts in the middle of beautiful rice fields and it is fun to spoil the eyes seeing the vast rice fields accompanied by artistic and cultural performances from the village community of Denai Lama.

Published: February 2023

COVID-19 pandemic is a very rare disease and greatly affects the world of tourism in general and the world of hospitality in particular. The way that is used to be has totally changed. The number of guests decreased drastically due to the restrictions (lockdown) as well as the implementation of health protocols implemented in our country. Parapat, which is known as a city that is always full of tourists, now facing a new problem dealing with the coming of tourists. The hotel occupancy rate immediately dropped drastically. Many room reservations have been cancelled. For this reason, the researcher took the title of marketing strategy in this COVID-19 pandemic. What is being done is that the owner should take an action and the marketing department continues to work hard to find ways to keep hotel survived. These various strategies are important to do because they involve hotel operations and also the save the hotel workers not to be jobless. A positive market response is the result of a marketing strategy that is acceptable to the market. The research method used is a qualitative way by conducting interviews with informants. The conclusion obtained is that the hotel is able to overcome the problem of reducing guests during this covid 19. Therefore the strategies happened in Parapat could be implemented as a model to be applied in other areas or by making changes in the form of adaptation in other areas.

FEMICIDIOS, TRAVESTICIDIOS Y TRANSFEMICIDIOS EN LA LITERATURA ULTRACONTEMPORÁNEA LATINOAMERICANA
Authors: Bianchi Paula Daniela 
Published: February 2023

Este artículo se propone explorar nuevos modos de enunciar las violencias ejercidas hacia los personajes femeninos, travestis y transgénero en la literatura latinoamericana ultracontemporánea centrándose en las categorías de ciudadanías y juricidades baldías (afectivas, sexuales, lingüísticas, geopolíticas); cuerpos precarios y violencias cruentas dentro de los estudios de género. Para esto, planteo un enfoque teórico que contrastará estos nuevos modos de narrar/mostrar que desplaza la atención de la descripción del cadáver y los detalles escabrosos de una gramática visual y pedagógica de la crueldad hacia una gramática de lo político y contrapedagógica configurando nuevos modos de relatar la muerte de mujeres, travestis y transgéneros presentado como una herramienta tecnopolítica.
La hipótesis general sostiene la reconstrucción de marcos de inteligibilidad que diseñan en la literatura del presente, los posibles recorridos de los femicidas, víctimas y familiares, en estos últimos se acentúan los periplos que realizan las familias en los pasillos de los Tribunales exigiendo “justicia para…”. Periplos que se debaten entre juricidades y trampas punitivas, connivencias policiales y duelos, búsquedas confesionales y sensaciones de (in)justicias.

El corpus analizado comprende

Siguiendo estas reflexiones, este artículo aborda diversas textualidades que se disputan la esfera literaria latinoamericana actual, exponiendo las experiencias y desafíos que se visibilizan, indagando algunas de las líneas de resistencia y de fuga que obligan a repensar no solo la crisis de los Estados nacionales modernos sino también los límites de las ciudadanías y los modos de transformar las condiciones sociales y políticas.
JUEGO DE ESPEJOS Y DESCOLONIZACIÓN EN
HUACO RETRATO
DE GABRIELA WIENER
Authors: Bernal Concepción Reverte 
Published: February 2023

Gabriela Wiener (Lima, 1975-) es considerada una escritora interesante en el panorama actual de la literatura peruana y su reciente obra
Huaco retrato
da fe de ello. Este relato está dividido en dos hilos narrativos que se alternan, desarrollándose como un juego de espejos entre lo autobiográfico y la recreación de la historia del tatarabuelo de la autora, Charles Wiener, origen de su apellido, el conflicto de Gabriela Wiener con su padre, poseedor de dos casas y de dos familias simultáneamente, y la situación personal de la escritora, vértice de un núcleo familiar de tres adultos infieles entre sí (poliamor), Europa y sus antiguas colonias, la inseguridad personal y el racismo. Gabriela Wiener pretende ser brutalmente sincera al expresarse, pero es evidente que en su libro existe una eficiente elaboración literaria, que revela un yo exhibicionista y complejo, que se vale del morbo que su peculiar organización familiar suscita para atraer lectores, pero que también sabe tratar temas profundos, de mayor alcance.

Los problemas que afronta Gabriela Wiener como inmigrante peruana de acusados rasgos latinos, primero en Barcelona y luego en Madrid, la llevan a reflexionar sobre el colonialismo y la ignorancia y desprecio del europeo hacia el latinoamericano, tal como refleja Charles Wiener en el libro de viajes que publicó a su vuelta de América. La dudosa reputación como explorador de este último contagia una oscura sombra sobre la sinceridad de la vida de sus descendientes.
Al final del relato, uno de los pasajes más duros en relación a la mentalidad colonial es la narración que se refiere a la antigua existencia de zoológicos humanos en las principales capitales europeas, una de ellas París, y como en ellos eran expuestos seres humanos en condición de esclavitud o casi total esclavitud. Gabriela Wiener piensa en el destino final que pudo tener un niño peruano que su antepasado llevó consigo a Francia, para demostrar así de qué forma un ser de un país atrasado podría evolucionar mediante una educación moderna. En última instancia, este rompecabezas familiar se manifiesta como una sucesión de “espejos”, no “enterrados” (Carlos Fuentes), sino “empañados” (Jorge Urrutia, en sus reflexiones sobre el realismo y el testimonio).
An Investigation of Open Clusters Berkeley 68 and Stock 20 Using CCD UBV and Gaia DR3 Data
Authors: Yontan Talar 
Published: February 2023

Abstract
We performed detailed photometric and astrometric analyses of the open star clusters Berkeley 68 and Stock 20. This was based on ground-based CCD UBV photometric data complemented by space-based Gaia Data Release 3 (DR3) photometry and astrometry. A total of 198 and 51 stars were identified as likely cluster members for Berkeley 68 and Stock 20, respectively. Two-color diagrams were used to derive the reddening and photometric metallicity for each cluster. The reddening for Berkeley 68 and Stock 20 is E(B − V) = 0.520 ± 0.032 mag and 0.400 ± 0.048 mag, respectively. Photometric metallicity [Fe/H] is −0.13 ± 0.08 dex for Berkeley 68 and −0.01 ± 0.06 dex for Stock 20. Keeping as constant reddening and metallicity, we determined the distance moduli and ages of the clusters through fitting isochrones to the UBV and Gaia-based color–magnitude diagrams. Photometric distances are d = 3003 ± 165 pc for Berkeley 68 and 2911 ± 216 pc for Stock 20. The cluster ages are 2.4 ± 0.2 Gyr and 50 ± 10 Myr for Berkeley 68 and Stock 20, respectively. Present-day mass function slopes were found to be Γ = 1.38 ± 0.71 and Γ = 1.53 ± 0.39 for Berkeley 68 and Stock 20, respectively. These values are compatible with the value of Salpeter. The relaxation times were estimated as 32.55 and 23.17 Myr for Berkeley 68 and Stock 20, respectively. These times are less than the estimated cluster ages, indicating that both clusters are dynamically relaxed. Orbit integration was carried out only for Berkeley 68 since radial velocity data were not available for Stock 20. Analysis indicated that Berkeley 68 was born outside the solar circle and belongs to the thin-disk component of the Milky Way.
MeerKAT Holography Measurements in the UHF, L, and S Bands
Authors: de Villiers Mattieu S. 
Published: February 2023

Abstract
Radio holographic measurements using the MeerKAT telescope are presented for each of its supported observing bands, namely UHF (544–1087 MHz), L (856–1711 MHz), and S (1750–3499 MHz). Because the UHF-band receiver design is a scaled version of that of the L band, the electromagnetic performance in these two bands are expectedly similar to one another. Despite also being linearly polarized, S-band receivers have an entirely different design and distinct performance characteristics from the lower two bands. As introduced in previous work for the L band, evidence of higher order waveguide mode activation also appears in S-band measurements but there are differences in its manifestation. Frequency-dependent pointing (beam squint), beamwidth, beam ellipticity, error beam, instrumental polarization, and cross-polarization power measurements are illustrated for each of MeerKAT’s observational bands in a side-by-side style to facilitate the comparison of features. The derivation of collimation errors and main reflector surface errors from measurements made at these relatively low observation frequencies is also discussed. Results include elevation and ambient temperature effects on collimation, as well as the signatures of collimation degrading over time. The accompanying data release includes a snapshot of full Jones matrix primary beam patterns for all bands and antennas with corresponding derived metrics.
A Multilevel Scheduling Framework for Distributed Time-domain Large-area Sky Survey Telescope Array

Published: February 2023

Abstract
Telescope arrays are receiving increasing attention due to their promise of higher resource utilization, greater sky survey area, and higher frequency of full space-time monitoring than single telescopes. Compared with the ordinary coordinated operation of several telescopes, the new astronomical observation mode has an order of magnitude difference in the number of telescopes. It requires efficient coordinated observation by large-domain telescopes distributed at different sites. Coherent modeling of various abstract environmental constraints is essential for responding to multiple complex science goals. Also, due to competing science priorities and field visibility, how the telescope arrays are scheduled for observations can significantly affect observation efficiency. This paper proposes a multilevel scheduling model oriented toward the problem of telescope-array scheduling for time-domain surveys. A flexible framework is developed with basic functionality encapsulated in software components implemented on hierarchical architectures. An optimization metric is proposed to self-consistently weight contributions from time-varying observation conditions to maintain uniform coverage and efficient time utilization from a global perspective. The performance of the scheduler is evaluated through simulated instances. The experimental results show that our scheduling framework performs correctly and provides acceptable solutions considering the percentage of time allocation efficiency and sky coverage uniformity in a feasible amount of time. Using a generic version of the telescope-array scheduling framework, we also demonstrate its scalability and its potential to be applied to other astronomical applications.
Forecasts on the Dark Matter Density Profiles of Dwarf Spheroidal Galaxies with Current and Future Kinematic Observations
Authors: Guerra Juan , Geha Marla , Strigari Louis E. 
Published: February 2023

Abstract
We forecast parameter uncertainties on the mass profile of a typical Milky Way dwarf spheroidal galaxy (dSph) using the spherical Jeans equation and Fisher matrix formalism. For a Draco-like system we show that radial velocity measurements for 1000 individual stars can constrain the mass contained within the effective radius of a dSph to within 5%. This is consistent with constraints extracted from current observational data. We compare two systems, a cusp and core, and demonstrate that a minimum sample of 100,000 (10,000) stars with both radial and proper motions measurements is required to disentangle their inner slopes at the 2σ (1σ) level. If using the log-slope measured at the half-light radius as a proxy for differentiating between a core or cusp slope, only 1000 line-of-sight and proper motions measurements are required; however, we show this choice of radius does not always unambiguously differentiate between core and cusped profiles. Once observational errors are below half the value of the intrinsic dispersion, improving the observational precision yields little change in the density profile uncertainties. The choice of priors in our profile shape analysis plays a crucial role when the number of stars in a system is less than 100 but does not affect the resulting uncertainties for larger kinematic samples. Our predicted 2D confidence regions agree well with those from a full likelihood analysis run on a mock kinematic data set taken from the Gaia Challenge, validating our Fisher predictions. Our methodology is flexible, allowing us to predict density profile uncertainties for a wide range of current and future kinematic data sets.
Cosmic-Ray Acceleration and Nonthermal Radiation at Accretion Shocks in the Outer Regions of Galaxy Clusters

≳ 102. Although strong accretion shocks are expected to be efficient accelerators of cosmic rays (CRs), nonthermal signatures of shock-accelerated CRs around clusters have not been confirmed, and detailed acceleration physics at such shocks has yet to be understood. In this study, we first establish through two-dimensional particle-in-cell simulations that at strong high-β shocks electrons can be pre-energized via stochastic Fermi acceleration owing to the ion Weibel instability in the shock transition region, possibly followed by injection into diffusive shock acceleration. Hence, we propose that the models derived from conventional thermal leakage injection may be employed for the acceleration of electrons and ions at accretion shocks as well. Applying these analytic models to numerical shock zones identified in structure formation simulations, we estimate nonthermal radiation, such as synchrotron and inverse Compton (IC) emission due to CR electrons and π
0-decay γ-rays due to CR protons, around simulated clusters. Our models with injection parameter Q ≈ 3.5–3.8 predict synthetic synchrotron maps, which seem consistent with recent radio observations of the Coma Cluster. However, the detection of nonthermal IC X-rays and γ-rays from accretion shocks would be quite challenging. We suggest that the proposed analytic models may be adopted as generic recipes for CR production at cosmological shocks.
