Malaise dan Lambang Kekayaan Ekonomi Penguasa Lokal di Palembang, 1929–1942
Authors: Irwanto Dedi 
Published: February 2019

This is an article on economic history, particularly on the economic growth of Palembang’sUluan local elites. But the main focus of the article is to understand and interpret other phenomenon that appeared as the product of that economic growth; its social-cultural implications that was present as a social reality of those economic conditions. It focuses on the creation of emblems of symbolic power in its political and economic manifestations. The emblems of economic wealth is seen as a symbol. As a symbol, this emblem represented meanings with several important functions, not merely as material collection, but also through a sociocultural lense; as the effort to create and contest with its peers or as an asimilative or adaptive process and a process of resistance to other groups that are ‘above’ its structure. The symbolic emblems of local power changed during the depression era of 1929. In a period where significant amount of wealth was lost, theuluan Palembang bucked the trend and appeared as new money (orang kaya baru) with all their new atributes of wealth.
Foreign Investment and the Middle Income Trap in Southeast Asia
Authors: Henley David 
Published: February 2019

This article focuses on the post-colonial catch-up by Southeast Asian nations with developed countries. The article offers an analysis of the nature and causes of the middle income trap in Southeast Asia. It discusses various interpretations of this concept, concluding with the dichotomy between laissez-faire and interventionist development strategies. Empirical evidence is provided from the automotive industry in Malaysia and Thailand. Two rival explanations of the lack of strong interventionist policies in Southeast Asia are given, one stressing the weakness of political pressure on national governments, the other linked up with historical patterns of ethnic specialization and division. The argument draws on secondary sources and reflects on implications for the study of Indonesian economic history in the colonial era.

Authors: Rodríguez Araneda María José 
Published: February 2019

La investigación tuvo como objetivo comprender y describir cualitativamente la representación social de las condiciones y experiencias vitales fuente de la felicidad en los discursos de agentes socializadores en materia de bienestar y calidad de vida. Se analizó además si estas atribuciones se condicen con los hallazgos aportados desde la psicología positiva. El estudio fue no experimental, transeccional, transcultural y cualitativo con muestras no probabilísticas de estudiantes y profesionales de la salud y la educación en Chile e Italia. Se aplicaron cuestionarios de preguntas abiertas a estudiantes de ambos sexos de carreras de psicología, obstetricia y afines de entre 18 y 38 años de edad. Se realizaron grupos focales con estudiantes y profesionales de ambos sexos, incluyendo educadores, psicólogos y profesionales afines, con edades entre los 22 y 67 años. Las personas atribuyeron la felicidad a condiciones externas (afectos y la libertad personal) e internas (capital psicológico). Entre las fuentes de la felicidad el discurso equilibró experiencias de satisfacción por suscepción (rol pasivo), como por realización (rol activo). Los alcances de dichas experiencias variaron de lo individual a lo colectivo. Se identificó un núcleo común de la representación social para ambos colectivos, que incluyó elementos que la psicología positiva ha relacionado a la felicidad. Esta información orienta la formación de los profesionales que ejercen influencia en los estilos de vida de la población.
Ansiedad Social Consumo Riesgoso de Alcohol en Adolescentes Mexicanos
Authors: Jiménez-López. Leticia María , Jurado Cárdenas Samuel 
Published: February 2019

Gradualmente se incrementa la investigación acerca de la fobia social, argumentando asociación entre ésta y diversas medidas de disfuncionalidad. Se obtuvieron datos sociodemográficos, mediciones de ansiedad social y de consumo de alcohol, de 3164 adolescentes mexicanos escolarizados voluntarios (hombres y mujeres) entre 12 y 18 años de edad ( = 14.7, DE 1.7), turno escolar (matutino o vespertino) y actividades extracurriculares (realizar o no actividades deportivas, artísticas y tener o no una relación de noviazgo). Se formaron dos grupos: el primero con bajo y el segundo con alto grado de ansiedad social, y se compararon sus niveles de consumo de alcohol, encontrando que: contrario a lo que establece la literatura del tema en adultos, el patrón de consumo de alcohol en los grupos de adolescentes de alta y baja ansiedad social, no presentó diferencias estadísticamente significativas (X2 = 1.201, gl = 2, p = .361). Probablemente, las diferencias reportadas en el consumo de alcohol entre adultos social y no socialmente ansiosos, surjan sólo en ciertas variantes de la fobia social, o bien, se requiere de otras variables mediadoras, entre fobia social y el consumo abusivo de alcohol.

Authors: Villavicencio-Ayub Erika , Jurado Cárdenas Samuel , Valencia Cruz. Alejandra 
Published: February 2019

El objetivo de este estudio fue evaluar los niveles de engagement en el trabajo en las organizaciones ubicadas en la Ciudad de México, usando pruebas estandarizadas, para determinar su relación con la ocurrencia del síndrome de desgaste ocupacional (SDO), la socialización organizacional (SO), y la resiliencia psicológica. A una muestra de 1110 empleados se le aplicaron: el Utrecht Work Engagement Scale, el Inventario de Socialización Organizacional, la Escala de Desgaste Ocupacional, y la Escala de Resiliencia Mexicana. El análisis de trayectorias mediante ecuaciones estructurales tuvo buen ajuste al modelo y arrojó relaciones causales entre las diferentes variables, específicamente, estábamos interesados en ver si la SO y la Resiliencia influyen en la ocurrencia del engagement. El modelo mostró un buen ajuste a los datos y sugirió que la SO y la resiliencia afectan positivamente al engagement en el trabajo. Por el contrario, todas estas mediciones fueron disminuidas en los casos de SDO, confirmando también que el engagement se comporta en forma positiva y opuesta al SDO. Estos hallazgos pueden ser utilizados para diseñar intervenciones efectivas para prevenir el SDO y promover comportamientos positivos como el engagement.

Ambon as the capital of Maluku Province had been occupied by 3,558 farmers whose farming works have contributed to the production of estate commodities for about 1,169 tons. There were three estate commodities with significant contribution, namely clove, nutmeg, and coconut. The objective of research was to analyze the characteristics of estate farmers and the contribution of estate commodities on household income. Sample was determined purposively from Nusaniwe District, precisely 30 farmers from Nusaniwe Subdistrict, 60 farmers from Latuhalat Subdistrict, 50 farmers from Amahusu Subdistrict, and 60 farmers from Urimessing Subdistrict. Total sample was 200 farmers. Data were collected using questionnaire and depth interview with key informant. Data on respondent characteristic were analyzed through simple tabulation. Income count was used to analyze the contribution of each estate commodity on household income. Result of research showed that education, number of household member, side-job selection, land width, and commodity species were not varying across subdistricts. Contribution of clove and nutmeg to household income was found as high for 70 – 80 %, while that of coconut reached only 10 – 20%. Side-job activity as fisher and construction worker gave contribution to household income for 5 – 10%.

Derivation of Motor Mean Phase Currents in PMSM Drives Operating with Low Switching-to-Fundamental Frequency Ratio
Authors: Jarzebowicz Leszek 
Published: February 2019

Abstract
Pulse width modulation (PWM) of inverter output voltage causes the waveforms of motor phase currents to consist of distinctive ripples. In order to provide suitable feedback for the motor current controllers, the mean value must be extracted from the currents’ waveforms in every PWM cycle. A common solution to derive the mean phase currents is to sample their value at the midpoint of a symmetrical PWM cycle. Using an assumption of linear current changes in steady PWM subintervals, this midpoint sample corresponds to the mean current in the PWM cycle. This way no hardware filtering or high-rate current sampling is required. Nevertheless, the assumption of linear current changes has been recently reported as over simplistic in permanent magnet synchronous motor (PMSM) drives operating with low switching-to-fundamental frequency ratio (SFFR). This, in turn, causes substantial errors in the representation of the mean phase currents by the midpoint sample. This paper proposes a solution for deriving mean phase currents in low SFFR PMSM drives, which does not rely on the linear current change assumption. The method is based on sampling the currents at the start point of a PWM cycle and correcting the sampled value using a model-based formula that reproduces the current waveforms. Effectiveness of the method is verified by simulation for an exemplary setup of high-speed PMSM drive. The results show that the proposed method decreases the error of determining the mean phase currents approximately 10 times when compared to the classical midpoint sampling technique.
Evaluation of Predictive Capabilities of Regression Models and Artificial Neural Networks for Density and Viscosity Measurements of Different Biodiesel-Diesel-Vegetable Oil Ternary Blends
Authors: Gulum Mert , Kutlu Onay Funda , Bilgin Atilla 
Published: February 2019

Abstract
Nowadays, biodiesel and vegetable oils have received increasing attention as renewable clean alternative fuels to fossil diesel fuel because of decreasing petroleum reserves and increasing environmental concerns. However, the straight use of biodiesel and vegetable oils in pure form results in several operational and durability problems in diesel engines because of their higher viscosity than fossil diesel fuel. One of the most used methods for solving the high viscosity problem is to blend them with fossil diesel fuel or alcohol. The reliable viscosity and density data of various biodiesel-diesel-alcohol ternary blends or biodiesel-diesel binary blends are plentifully available in existing literature, however, there is still the scarcity of dependable measurement values on different biodiesel-diesel-vegetable oil ternary blends at various temperatures. Therefore, in this study, waste cooking oil biodiesel (ethyl ester) was produced, and it was blended with fossil diesel fuel and waste cooking oil at different volume ratios to prepare ternary blends. Viscosities and densities of the ternary blends were determined at different temperatures according to DIN 53015 and ISO 4787 standards, respectively. The variation in viscosity with respect to temperature and oil fraction and the change of density vs. temperature were evaluated, rational and exponential models were proposed for these variations, and these models were tested against the density and viscosity data measured by the authors, Nogueira et al. and Baroutian et al. by comparing them to Gupta et al. model, linear model, Cragoe model and ANN (artificial neural networks) previously recommended in existing literature.

The article presents examples of characteristics specific to the above processes, determined based on the results of studies of individual types of engines. Currently ongoing studies allow for constructing strategies for naval gas turbines, operated in the Polish Navy, according to technical condition.
Determination of Dynamic Characteristics of Austenitic Steel to be Utilized in Fem Simulation and its Verification
Authors: Szturomski Bogdan , Świątek Krzysztof , Jurczak Wojciech 
Published: February 2019

Abstract
This paper presents the dynamic mechanical properties of austenitic steel with improved durability, which is used in the construction of hulls of minesweepers, mine destroyers, submarines and other naval vessels. Dynamic tensile tests performed on the steel samples using a rotary hammer with a strain rate of up to 1000 s-1 allowed determination of elastic-plastic characteristics of the material in the form of a polynomial of Johnson-Cook constitutive model, taking into account the influence of strain rate and temperature. A characteristic of this type is utilized in numerical calculations in the CAE software. The obtained characteristics were experimentally verified by bending tests of flat samples with a drop-weight type impact hammer. Simultaneously numerical calculations were performed in order to compare the deformation state.
