Thriving Amidst the Pandemic: Examining the Lived Experiences of Work from Home Filipino Teachers

The purpose of this study is to investigate the mental, physical, emotional, social, and spiritual experiences of work-from-home (WFH) Filipino teachers. It also provides descriptions of the positive and negative aspects of working from home and how they adapt to the new culture. This study describes exceptional or new thoughts and feelings of WFH Filipino teachers. Using a qualitative phenomenological methodology, the researchers explored teachers’ lived experiences in teaching in a work-from-home environment. This study included ten (10) teachers from both public and private schools in Metro Manila.   Analyses of the data revealed key themes from the teachers’ perspectives of the work-from-home environment. Respondents accepted the new culture of working from home, opened their minds to all possibilities, and were eager to learn new things to adapt to changes. Online teaching-learning is not possible without the respondents' participation in training and seminars. Technical issues, communication concerns, student learning conditions, family concerns, household issues, and health conditions are some of the challenges in teaching and working at home based on the research.  Teacher participants expressed that WFH experiences were challenging and exhausting but they found it fulfilling as well. They cultivated the teachers’ traits of being flexible, innovative, dynamic, and sociable despite the many challenges that they have encountered in the intricate setup to enhance success and effectiveness in the teaching and learning process

Reestimation of shadow prices for the Philippines

context of project evaluation. Early contributions to the literature formulated methodologies and framework for estimating social opportunity costs of goods and resources, with an underlying objective of maximizing income, regardless of its distributional impact. These earlier contributions constitute what is now referred to as the "traditional approach." Well-known proponents of this approach include Arnold Harberger and Edward Mishan. Since then, a lot of contributions have been added to the literature. New approaches were developed, which, in contrast with the traditional view, sought to value differentially a project's distributional impact and its impact between saving and consumption. The most widely cited contributions to the new approach include Dasgupta, Marglin and Sen (1972), Little and Mirrlees (1968 and 1974) and Squire and van der Tak (1975).1 There are also studies on shadow prices in the Philippine context. The first and most complete set of estimates of shadow prices for the Philippines based on empirical data and analytically deduced formulas, can be found in Bautista, Power and Associates (1979). It provides estimates of shadow prices of foreign exchange ( using 1974 data), labor (using 1977 data), and capital (based on 1974 data). The estimates were updated and methodologies were improved in Medalla and Power (1984). After years of debate, the subject of cost-benefit analysis, particularly the concept of using distribution weights, remains controversial. This study would not attempt to end the debate. It does not intend to resolve all the controversial issues in cost-benefit analysis. Rather, its objectives are much more modest. It is primarily addressed to actual practitioners of project evaluation and is thus designed to be practical. The main objectives of the study are : 1. to provide the most recent estimates of the basic parameters in shadow pricing, namely, the shadow exchange rate, the marginal productivity of capital, and the opportunity cost of labor; 2. to spell out procedures for estimating these parameters to enable convenient and consistent reestimation in the future; and 3. to clarify the differences between approaches and trace their impact on the parameters used in order to easily shift from one approach to another. The study is divided into six parts. Part 1 gives a brief background on the topic while part II provides an overview of the concept of shadow pricing and the basic approaches to cost- benefit analysis. The succeeding parts discuss how to estimate shadow prices. In particular, part in shows how to estimate the shadow exchange rate, part IV the marginal productivity of capital and part V, the shadow wage rate. Finally, part VI discusses how to estimate accounting price ratios for frequently used (nontraded) inputs such as electricity and transportation services

Analysis and Experimental Implementation of Grid Frequency Regulation using Behind-the-Meter Batteries Compensating for Fast Load Demand Variations

This paper proposes a new grid frequency regulation (GFR) scheme using behind-the-meter battery energy storage systems (BESSs). The fast dynamic responses of the electrical BESSs enable buildings to compensate for the high-frequency components of load demand variations, through direct load control (DLC). An electrical system in a building, along with its building-level and device-level controllers, is considered to address the difficulties in the application of DLC, especially in communicating with several small-scale BESSs. A small-signal analysis is carried out using the aggregated responses of the generators and the DLC-enabled buildings to investigate the proposed GFR scheme, particularly with respect to the feedback controllers for the buildings. Simulation studies are performed using a test grid for various penetrations of the DLC-enabled buildings, and the test grid is implemented using a laboratory-scale microgrid. The proposed GFR is effective in reducing the frequency deviations and required reserve capacity of the generators, which is achieved by making small variations in the state-of-charge of the behind-the-meter battery.1172Ysciescopu

Estocástica: finanzas y riesgo. Volumen 6, número 1 (enero-junio, 2016)-

1 archivo PDF (114 páginas). EFR61"En este número presentamos dos metodologías, con distintas aplicaciones y variantes, que son ampliamente usadas en el sistema financiero. Por un lado, la métrica del Valor en Riesgo, VaR, que desde la última década del siglo pasado empezó a usarse de manera generalizada para cuantificar el riesgo, y cuya importancia ha crecido al ser adoptada como indicador de éste por los reguladores a nivel internacional. Por otra parte, se encuentra la teoría de cópulas, la cual tiene como una de sus principales aplicaciones en las finanzas, la medición de la dependencia entre distintas variables, debido a que, dada una distribución multivariada arbitraria, ésta puede descomponerse en sus marginales y en su estructura de dependencia. A principios de este siglo, el concepto de cópula se utilizó en los modelos VaR con distribuciones gaussianas y t-student para modelar dependencias sectoriales. Y a partir de entonces, tanto los modelos VaR como la teoría de cópulas, con sus distintas variantes, han sido utilizadas extensivamente.

Hydrometallurgical removal of uranium and thorium from Ethiopian tantalite ore

This study focused on the leaching of uranium and thorium from a high grade Ethiopian tantalite ore using sulfuric acid. The effects of variables such as acid concentration, temperature and leaching time were studied. In general, the leaching efficiency of uranium increases with increasing temperature from 100 to 300 °C whereas the opposite trend was observed for thorium. The amount of uranium leached increased from 69.1% at contact time of 1 hr to 88.6% when the tantalite ore was leached for 3 hrs. On the other hand, for the experiments conditions considered in this study, the leaching behavior of uranium and thorium did not change significantly with varying sulphuric acid concentration from 70 to 90 wt%. Overall, the highest dissolution of uranium and thorium were achieved at 100 °C, 70 wt% H2SO4 concentration and 1 hr contact time
