Published: May 2019

Bepang merupakan produk olahan beras yang telah digiling dan dicampur bersama dengan gula putih dan gula merah sehingga memberikan cita rasa yang khas. Berkaitan dengan aspek pemasaran produk Bepang, promosi memegang peranan yang penting. Promosi dapat dilakukan melalui berbagai cara, seperti personal selling dan periklanan. Penelitian ini bertujuan untuk menjelaskan bagaimana tahapan dalam melakukan personal selling dan periklanan dari produk Bepang dan mengidentifikasi pengaruh personal selling dan periklanan terhadap volume penjualan produk Bepang. Personal Selling dan periklanan dilakukan melalui dua tahapan. Tahapan pertama bertujuan untuk secara acak menentukan target area promosi berdasarkan jarak dan langkah kedua adalah melakukan aktivitas personal selling dan periklanan selama 16 hari. Sementara itu, analisis pengaruh personal selling dan perikalanan terhadap volume penjualan dilakukan dengan analisis regresi berganda dan menghasilkan persamaan Y = 51,88-0,8151x1-0,7347x2. Berdasarkan persamaan tersebut dapat diidentifikasi bahwa semakin jauh jarak yang ditempuh untuk melakukan penjualan melalui personal selling dan periklanan maka semakin sedikit volume penjualan yang akan didapat. Sementara itu, koefisien determinasi (R2) menunjukkan nilai 0,7214. Hal ini berarti bahwa personal selling dan perikalanan berpengaruh terhadap volume penjualan sebesar 72,14%. Uji parsial (uji t) untuk hasil personal selling menunjukkan bawah thitung> ttabel (2,31817> 2,160) dan untuk periklanan  menujukkan hasil bahwa thitung> ttabel (2, 8912> 2,1604) yang berarti bahwa personal selling dan periklanan memiliki hubungan yang signifikan dengan volume penjualan. Selain itu uji regresi simultan (uji F) menghasilkan nilai Fhitung > Ftabel (16,3890> 3,81) yang juga dapat dikatakan bahwa personal selling dan periklanan secara bersamaan mempengaruhi volume penjualan.

The Complexity of Work for Women who are HIV Positive: A Case Study in DKI Jakarta
Authors: Faizah Andi Nur
Published: May 2019

The phenomenon of HIV-AIDS transmission places women in a difficult situation. The loss of family members such as husbands due to AIDS leaves women living with HIV positive in a struggle to access sources of livelihood. The condition of themselves as PLWHA, concerns about being stigmatized, caring for family members, and earning a living are the burdens of life they have to face. In this regard, this paper explores the complexity of the work of HIV-positive women. This study uses a qualitative method with a feminist perspective to get a complete picture of the livelihood of HIV-positive women. Based on interviews with five HIV-positive women, the findings found a link between social, identity, and gender categories that affect their livelihoods. HIV-positive women also transform themselves into their “normal” self by pretending to be healthy, able to work, have quality, and be independent. This is done as a form of resistance to the stigma attached to PLWHA.

 

 
Women Workers in the Indonesian Labor Market: Inevitable Marginalization
Authors: Ismalina Poppy -
Published: May 2019

By conducting descriptive statistical analysis and the establishment of two econometric models, this study proves that the marginalization of women in the Indonesian labor market still occurs even though the quality of Indonesian women from the level of education and work participation is increasing. The phenomenon of marginalization of women is characterized by 1) the wage gap due to gender differences, namely the wages received by female workers are lower than male workers for all types of work; 2) the chances of men to find work are far higher than women in the Indonesian labor market. The study concludes that the wage gap due to gender differences is not due to competition in the labor market but rather due to the assumption that working women are secondary and supplementary breadwinners in their households, and the role that they can be play is only an extension of their domestic role. Thus, the main cause of the marginalization of women in the labor market is the low awareness of gender equality, something which has already taken root in Indonesia.

Published: May 2019

The main question in this article is how is the achievement of women political movements after 20 years of reformation in Indonesia? This article elaborates two things which are foundation reasons for examining why women movement in politics have stagnant position and offering strategic agenda that could be discussed for attracting young women in political arena. There are three main reasons to see women movement after Reformation 1998. First aspect is considering civil society characteristics and also party politics in Indonesia which are unique. Second issue is there are established political interaction between both organizations. Third issue are concerning on electoral competition that is important to highlight. That is how to endorse the winning of women candidates in each election could be achieved. We believe that to build connectivity and linkage between young women generation and party politics is strategic step for party politics for resolving the necessity of women candidacy and their winning opportunities in elections.

Political and Legal Novelty as the Contribution of Indonesian Women’s Movement in the Advocacy on Affirmative Policy in Election and Law on the Abolition of Domestic Violence
Authors: Dhewy Anita , Sandiata Bella
Published: May 2019

This article discusses the novelty of the women’s movement in encouraging women’s political representation and advocating for the elimination of domestic violence. Data is obtained through interviews with actors involved in the women’s movement, especially actors from civil society organizations. The results of the study show that the women’s movement in the Advocacy on Affirmative Policy in Election becomes a sign of the inclusion of women in the political agenda. While the women’s movement in the advocacy for Law on the Abolition of Domestic Violence dismantles private and public dichotomies that are detrimental to women in the context
of domestic violence. This study also shows that women’s movements need strong concepts, adaptive strategies and synergies with various elements to be able to push the women’s agenda and encourage change.
Un modelo de gestión turística basado en gobernanza, como mejor alternativa para el desarrollo del turismo sostenible en la Parroquia Rural de Calderón
Authors: Fuentes Moreno Anibal , García Martínez Darwin Abdón
Published: May 2019

La gobernanza como elemento principal para el desarrollo del turismo sostenible en las parroquias rurales de Ecuador, presenta varios retos. En primer lugar, encontramos que el Estado, a través del Consejo Nacional de Competencias (2016, p. 7), restringe al nivel de gestión las competencias enmateria de turismo de las parroquias rurales. Y, en segundo lugar, y estrechamente ligado al condicionamiento anterior, tenemos que los pocos recursos turísticos de que disponen las parroquias rurales han sufrido un proceso de estancamiento en su desarrollo, o lo que es peor, un proceso dedegradación de su entorno, que impide avizorar un proceso de desarrollo inmediato y sostenible.Sin embargo, elementos como una buena capacidad de gestión de los Gobiernos Autónomos Descentralizados de las Parroquias Rurales, sumada a una buena capacidad de liderazgo de sus representantes, generan la certeza de que impulsar un proceso de desarrollo del turismo sostenible sobre la base de la aplicación de los principios de buena gobernanza, es la mejor opción de que se dispone en la actualidad para lograr (con base en la toma de decisiones consensuadas con los actores de la gobernanza) el desarrollo económico y social de los territorios.Siendo así, la propuesta de un modelo de gestión turística basado en la gobernanza y, fundamentalmente, en la aplicación de sus principios, permite plantear un nuevo modelo de desarrollo del turismo en el sector rural, un modelo que generará resultados medibles a corto, mediano y largo plazosa partir de la implementación de procesos de medición de indicadores, los cuales evidenciarán los aciertos y permitirán rectificar los errores de gestión e implementación en las parroquias rurales de Ecuador.
Connecting the Scales: Large Area High-resolution Ammonia Mapping of NGC 1333
Authors: Dhabal Arnab , Mundy Lee G. , Chen Che-yu , Teuben Peter , Storm Shaye
Published: May 2019

We use NH3 inversion transitions to trace the dense gas in the NGC 1333 region of the Perseus molecular cloud. NH3 (1, 1) and NH3 (2, 2) maps covering an area of 102 square arcminutes at an angular resolution of ∼3.″7 are produced by combining Very Large Array interferometric observations with Green Bank Telescope single-dish maps. The combined maps have a spectral resolution of 0.14 km s−1 and a sensitivity of 4 mJy/beam. We produce integrated intensity maps, peak intensity maps, and dispersion maps of NH3 (1, 1) and NH3 (2, 2) and a line-of-sight velocity map of NH3 (1, 1). These are used to derive the optical depth for the NH3 (1, 1) main component, the excitation temperature of NH3 (1, 1), and the rotational temperature, kinetic temperature, and column density of NH3 over the mapped area. We compare these observations with the CARMA J = 1–0 observations of N2H+ and H13CO+ and conclude that they all trace the same material in these dense star-forming regions. From the NH3 (1, 1) velocity map, we find that a velocity gradient ridge extends in an arc across the entire southern part of NGC 1333. We propose that a large-scale turbulent cell is colliding with the cloud, which could result in the formation of a layer of compressed gas. This region along the velocity gradient ridge is dotted with Class 0/I young stellar objects, which could have formed from local overdensities in the compressed gas leading to gravitational instabilities. The NH3 (1, 1) velocity dispersion map also has relatively high values along this region, thereby substantiating the shock layer argument.
Strong Scattering of ∼keV Pickup Ions in the Local Interstellar Magnetic Field Draped around Our Heliosphere: Implications for the IBEX Ribbon's Source and IMAP
Authors: Zirnstein E. J. , McComas D. J. , Schwadron N. A. , Dayeh M. A. , Heerikhuisen J. , Swaczyna P.
Published: May 2019

The leading hypothesis for the origin of the Interstellar Boundary Explorer(IBEX) “ribbon” of enhanced energetic neutral atoms (ENAs) from the outer heliosphere is the secondary ENA mechanism, whereby neutralized solar wind ions escape the heliosphere, and after several charge-exchange processes, may propagate back toward Earth primarily in directions perpendicular to the local interstellar magnetic field (ISMF). However, the physical processes governing the parent protons outside of the heliopause are still unconstrained. In this study, we compute the “spatial retention” model proposed by Schwadron & McComas in a 3D simulated heliosphere. In their model, pickup ions outside the heliopause that originate from the neutral solar wind are spatially retained in a region of space via strong pitch angle scattering before becoming ENAs. We find that the ribbon's intensity and shape can vary greatly depending on the pitch angle scattering rate both inside and outside the spatial retention region, potentially contributing to the globally distributed flux. The draping of the ISMF around the heliopause creates an asymmetry in the average distance to the ribbon's source as well as an asymmetry in the ribbon's shape, i.e., a radial cross section of ENA flux through the circular ribbon. The spatial retention model adds an additional asymmetry to the ribbon's shape due to the enhancement of ions in the retention region close to the heliopause. Finally, we demonstrate how the ribbon's structure observed at 1 au is affected by different instrument capabilities, and how the Interstellar Mapping and Acceleration Probe may observe the ribbon.
Inaccuracy of Spatial Derivatives in Riemann Solver Simulations of Supersonic Turbulence
Authors: Pan Liubin , Padoan Paolo , Nordlund Åke
Published: May 2019

We examine the accuracy of spatial derivatives computed from numerical simulations of supersonic turbulence. Two sets of simulations, carried out using a finite-volume code that evolves the hydrodynamic equations with an approximate Riemann solver and a finite-difference code that solves the Navier–Stokes (N–S) equations, are tested against a number of criteria based on the continuity equation, including exact results at statistically steady state. We find that the spatial derivatives in the N–S runs are accurate and satisfy all the criteria. In particular, they satisfy our exact results that, at steady state, the average of the velocity divergence conditioned on the flow density and the conditional average of the advection of density both vanish at all density levels. On the other hand, the Riemann solver simulations fail all the tests that require accurate evaluation of spatial derivatives, resulting in apparent violation of the continuity equation, even if the solver enforces mass conservation. In particular, analysis of the Riemann simulations may lead to the incorrect conclusion that the

work tends to preferentially convert kinetic energy into thermal energy, which is inconsistent with the exact result that the energy exchange by

work is symmetric in barotropic supersonic turbulence at steady state. The inaccuracy of spatial derivatives is a general problem in the post-processing of simulations of supersonic turbulence with Riemann solvers. Solutions from such simulations must be used with caution in post-processing studies concerning the spatial gradients.
Energy Dissipation in Large Collisions—No Change in Planet Formation Outcomes
Authors: Deienno Rogerio , Walsh Kevin J. , Kretke Katherine A. , Levison Harold F.
Published: May 2019

It is often asserted that more accurate treatment of large collisions in planet formation simulations will lead to vastly different results—in particular a lower final angular momentum deficit (AMD—commonly used to measure orbital excitement). As nearly all simulations to date consider perfect merging (100% energy dissipation) during embryo–embryo collisions, and typically end up with an overexcited final terrestrial planetary system, it has been suggested that a better treatment of energy dissipation during large collisions could decrease the final dynamical excitation (or AMD). Although some work related to energy dissipation has been done (mostly during the runaway growth phase when planetesimals grow into protoplanets), this had never been fully tested in the post-runaway phase, where protoplanets (embryos) grow chaotically into planets via large collisions among themselves. In this work, we test varying amounts of energy dissipation within embryo–embryo collisions, by assuming a given coefficient of restitution for collisions. Our results show that varying the level of energy dissipated within embryo–embryo collisions do not play any important role in the final terrestrial planetary system. We have found a strong linear correlation in our results related to the final number of planets formed and the final AMD. Additionally, reproducing the current radial mass concentration of the terrestrial planets, even when starting from an annulus of material, is challenging when modeling growth from planetesimals to planets.
Coronal Loop Transverse Oscillations Excited by Different Driver Frequencies
Authors: Afanasyev Andrey , Karampelas Konstantinos , Doorsselaere Tom Van
Published: May 2019

We analyze transverse oscillations of a coronal loop excited by continuous monoperiodic motions of the loop footpoint at different frequencies in the presence of gravity. Using the MPI-AMRVAC code, we perform three-dimensional numerical magnetohydrodynamic simulations, considering the loop as a magnetic flux tube filled in with denser, hotter, and gravitationally stratified plasma. We show the resonant response of the loop to its external excitation and analyze the development of the Kelvin–Helmholtz instability at different heights. We also study the spatial distribution of plasma heating due to transverse oscillations along the loop. The positions of the maximum heating are in total agreement with those for the intensity of the Kelvin–Helmholtz instability, and correspond to the standing wave antinodes in the resonant cases. The initial temperature configuration and plasma mixing effect appear to play a significant role in plasma heating by transverse footpoint motions. In particular, the development of the Kelvin–Helmholtz instability in a hotter loop results in the enhancement of the mean plasma temperature in the domain.

Anatomical and phylogenetic investigation of the genera Alabastrina Kobelt, 1904, Siretia Pallary, 1926, and Otala Schumacher, 1817 (Stylommatophora, Helicidae)
Authors: Kneubühler Jeannette , Hutterer Rainer , Pfarrer Beat , Neubert Eike
Published: May 2019

This study presents new insights in the anatomy of genital organs of some large helicid gastropods from northern Africa. The genetic analysis with the markers COI, 16S, H3, and 5.8 S rRNA+ITS2 reveales a high support for Alabastrina and Otala as separate evolutionary lineages within the Otalini. The position of Siretia as another separate lineage within the Otalini is discussed. “Tingitanaminetteidecussata” clusters within the O.xanthodon clade and confirms that the genus Tingitana can be synonymised with Otala. The genus Alabastrina differs from all other known genera by possession of a penial appendix. This character state is also found in topotypic A.tistutensis. Examination of the twin penial papilla system in Otala recovers a reduction of the proximal penial papilla in O.punctata. The position of Helixmurcica as a separate subspecies of O.lactea is not supported, and it is here considered to be a synonym of the latter species.

We analyze reports to identify the main concerns for managers, and compare the solutions implemented to address them, to evaluate the extent to which HIWP are adopted to meet these challenges.Design/methodology/approach: To conduct this study we carried out a systematic literature review, selecting reports by consulting firms and human resource management associations.Findings: Our key findings from this research suggest that HIWP are used as a lever for change to meet the challenges faced by HR managers in organizations, the most urgent of which are talent management and improving leadership.Research limitations/implications: The paper identifies possible lines of research that respond specifically to the interests of the professional ambit and would be better appreciated by HR managers in companiesPractical implications: The issues raised are relevant to HR professionals, allowing them to compare their priorities against those of managers occupying similar positions, and to view a selection of the most commonly used programs to solve priority problems. This enables HRMs to plan ahead and prepare by providing them with an overview of the most important challenges they have to face.Originality/value: On the one hand in the professional arena, as they provide professionals with an overview of the challenges they face, so they can plan optimal HR management programs, work methods geared and identify improvement opportunities. And on the other hand, in the academic sphere, our study opens possible future research lines that may contribute to the development of the profession, identify research lines that genuinely address the concerns of professionals and could help reduce the gap that some researchers have identified between the academic and professional spheres.
Strychnine: Old Remedy, Silent Killer
Authors: Hur Moon Hee , Havalad Vinod , Clardy Christopher
Published: May 2019

Toxin ingestion is a significant public health issue for children, accounting for hundreds of visits per day to emergency departments. The most common substances are household cleaning products, personal care products, and medications. This article describes an ingestion of a rare substance called strychnine, which is a plant-based odorless powder that was previously used as a nonspecific stimulant. This toxicity can mimic other ingestions, thus delaying diagnosis, so an increased awareness of the common symptoms and laboratory findings may lead to a more targeted management of strychnine poisoning.

Development of lymphoid progenitors requires a coordinated regulation of gene expression, DNA replication, and gene rearrangement. Chromatin-remodeling activities directed by SWI/SNF2 superfamily complexes play important roles in these processes. In this study, we used a conditional knockout mouse model to investigate the role of Smarca5, a member of the ISWI subfamily of such complexes, in early lymphocyte development. Smarca5 deficiency results in a developmental block at the DN3 stage of αβ thymocytes and pro-B stage of early B cells at which the rearrangement of Ag receptor loci occurs. It also disturbs the development of committed (CD73+) γδ thymocytes. The αβ thymocyte block is accompanied by massive apoptotic depletion of β-selected double-negative DN3 cells and premitotic arrest of CD4/CD8 double-positive cells. Although Smarca5-deficient αβ T cell precursors that survived apoptosis were able to undergo a successful TCRβ rearrangement, they exhibited a highly abnormal mRNA profile, including the persistent expression of CD44 and CD25 markers characteristic of immature cells. We also observed that the p53 pathway became activated in these cells and that a deficiency of p53 partially rescued the defect in thymus cellularity (in contrast to early B cells) of Smarca5-deficient mice. However, the activation of p53 was not primarily responsible for the thymocyte developmental defects observed in the Smarca5 mutants. Our results indicate that Smarca5 plays a key role in the development of thymocytes undergoing β-selection, γδ thymocytes, and also B cell progenitors by regulating the transcription of early differentiation programs.
Mer Bleue, Ontario, Arctic surrogate study site project, 2018 update: global navigation satellite system survey report
Authors: Prévost C , White H P
Published: May 2019

Natural Resources Canada (NRCan) has the mandate of providing essential geographic information. An improved knowledge of our physical environment represents one of the cores of this mandate. The Arctic is an important but challenging region to study, especially
for wetland monitoring. To reduce survey costs, researchers often use surrogate sites located in less remote areas when evaluating and developing applications. The Mer Bleue Bog Peatlands, a conveniently accessible sub-arctic wetland similar to many wetlands found in the Arctic environment, is being
used as arctic surrogate study site for the MBASSS Project.
This study site is used for the calibration and validation of various types of optical (spectral) remote sensing data acquired by several project partners using satellite, airborne and Unmanned Aerial Vehicle (UAV) platforms. Precisely geo-located products require ground control points (reference
points) which are visible to the sensor on the platform and whose geographic location is known with precision. To fulfill this need, high precision GNSS surveys are required.
This highly illustrated document describes in detail the methods and results of the GNSS surveys required for the geographic rectification of imagery, including Unmanned Aerial Vehicle photographs, airborne hyperspectral imagery, and space borne multi-spectral imagery acquired within the scope of
MBASSS during 2018.
Aging aerosol in a well-mixed continuous-flow tank reactor: an introduction of the activation time distribution
Authors: Friebel Franz , Mensah Amewu A.
Published: May 2019

Abstract. Two approaches are commonly used to simulate atmospheric aging processes in
the laboratory. The experiments are either performed in large aerosol
chambers (several m3) in order to achieve extended observation times or
in small chambers (< 1 m3), compensating for the short
observation times by elevated reactant concentrations. We present an
experimental approach that enables long observation times at atmospherically
relevant reactant concentrations in small chamber volumes by operating the
aerosol chamber as a continuous-flow stirred tank reactor (CSTR). We
developed a mathematical framework that allows the retrieval of data beyond
calculating mean values, such as O3 exposure or equivalent
atmospheric aging time, using the new metric, activation time
(tact). This concept was developed and successfully tested to
characterize the change in cloud condensation nuclei (CCN) activity of soot
particles due to heterogeneous ozone oxidation. We found very good agreement
between the experimental results and the theoretical predictions. This
experimental approach and data analysis concept can be applied for the
investigation of any transition in aerosol particles properties that can be
considered a binary system. Furthermore, we show how tact can be
applied to the analysis of data originating from other reactor types such as
oxidation flow reactors (OFRs), which are widely used in atmospheric
sciences. The new tact concept significantly supports the
understanding of data acquired in OFRs, especially those from deviating
experimental results in intercomparison campaigns.
Contributions of advection and melting processes to the decline in sea ice in the Pacific sector of the Arctic Ocean

Abstract. The Pacific sector of the Arctic Ocean (PA, hereafter) is a region sensitive
to climate change. Given the alarming changes in sea ice cover during recent
years, knowledge of sea ice loss with respect to ice advection and melting
processes has become critical. With satellite-derived products from the
National Snow and Ice Center (NSIDC), a 38-year record (1979–2016) of the
loss in sea ice area in summer within the Pacific-Arctic (PA) sector due to
the two processes is obtained. The average sea ice outflow from the PA to the
Atlantic-Arctic (AA) Ocean during the summer season (June–September) reaches
0.173×106 km2, which corresponds to approximately 34 %
of the mean annual export (October to September). Over the investigated
period, a positive trend of 0.004×106 km2 yr−1 is also
observed for the outflow field in summer. The mean estimate of sea ice
retreat within the PA associated with summer melting is 1.66×106 km2, with a positive trend of 0.053×106 km2 yr−1. As a result, the increasing trends of ice
retreat caused by outflow and melting together contribute to a stronger
decrease in sea ice coverage within the PA (0.057×106 km2 yr−1) in summer. In percentage terms, the melting
process accounts for 90.4 % of the sea ice retreat in the PA in summer,
whereas the remaining 9.6 % is explained by the outflow process, on
average. Moreover, our analysis suggests that the connections are relatively
strong (R=0.63), moderate (R=-0.46), and weak (R=-0.24) between
retreat of sea ice and the winds associated with the dipole anomaly (DA),
North Atlantic Oscillation (NAO), and Arctic Oscillation (AO), respectively.
The DA participates by impacting both the advection (R=0.74) and melting
(R=0.55) processes, whereas the NAO affects the melting process (R=-0.46).

La construcción de Nueva España: el mundo del libro
Authors: Vallejo Cervantes Gabriela
Published: May 2019

Desde la conquista del Nuevo Mundo, se dio un proceso complejo de apropiación de culturas y de integración global que involucraba a todos sus habitantes. ¿Podría la Nueva España definirse como un reino americano particular o un reino entre otros tantos dentro del ámbito de la Monarquía hispánica? Como una tensión entre ambos polos, el libro sería el soporte para transmitir, desde la segunda mitad del siglo XVI, una imagen que ensamblaría tanto su especificidad como reino, como la visión global otorgada a éste desde Europa.
“Il poco numero de’ libri Spagnuoli”: La defensa de España en las "Efemeridi letterarie di Roma" en el último tercio del siglo XVIII
Authors: Gimeno Puyol María Dolores
Published: May 2019

El auge cultural de la Roma del último tercio del siglo XVIII se reflejó en su vitalidad editorial y en la aparición de numerosas publicaciones periódicas, entre las cuales las Efemeridi letterarie di Roma (1772-1798), que reseñaron la producción propia y la europea. La proporción de libros españoles –cuya lista se ofrece aquí–, aunque no alcanzó el 2% de las reseñas, fue compensada por una decidida voluntad de subrayar tanto el pasado brillante, evidenciado en repertorios y obras historiográficas, como el presente ilustrado, visible en la literatura de gusto clásico y en los avances sociales o científicos. Se pretendía reivindicar una imagen positiva de España frente a los errores y manipulaciones de autores extranjeros y, así, construir junto a Italia un nuevo polo cultural frente al hegemónico francés desde los presupuestos de la Ilustración católica.
