Assessment for learning and cognitive process dimensions literacy of instructors in English

The general problem of this study was to determine the literacy level of instructors in English on assessment for learning and cognitive process dimensions in terms of the following parameters such as classroom assessment objective, classroom assessment theoretical basis, types of tests, content, and performance standards and competencies, and cognitive process dimensions. To achieve this aim, the researchers involved five university administrators, 15 instructors in English, and 225 college students during the school year 2020-2021. The questionnaire on the literacy level of instructors in English on the assessment of learning and cognitive process dimensions was utilized. The results were processed using statistical packages for social sciences (SPSS) and presented using appropriate tables and texts. The findings revealed that: first, although instructors in English are utilizing specific, measurable, attainable, relevant, and time-bound (SMART) learning objectives, they still have to distinguish between three learning domains; secondly, while instructors in English are excellent in identifying the diversity of students, they have to look for various assessment tools; third, though they have flexibility in crafting learning goals, and assess students holistically, they need to be familiar with levels of cognitive process in achieving profound assessment for learning

Low temperature dielectric anomalies in HoMnO_3: The complex phase diagram

The dielectric constant of multiferroic hexagonal HoMnO_3 exhibits an unprecedented diversity of anomalies at low temperatures (1.8 K< T <10 K) and under external magnetic fields related to magnetic phase transitions in the coupled system of Ho moments, Mn spins, and ferroelectric polarization. The derived phase diagram is far more complex than previously assumed including reentrant phases, phase transitions with distinct thermal and field hysteresis, as well as several multicritical points. Magnetoelastic interactions introduce lattice anomalies at the magnetic phase transitions. The re-evaluation of the T-H phase diagram of HoMnO_3 is demanded.Comment: 12 pages, 3 figure

Strong spin-lattice coupling in multiferroic HoMnO3_{3}: Thermal expansion anomalies and pressure effect

Evidence for a strong spin-lattice coupling in multiferroic HoMnO_3 is derived from thermal expansion measurements along a- and c-axis. The magnetoelastic effect results in sizable anomalies of the thermal expansivities at the antiferromagnetic (T_N) and the spin rotation (T_{SR}) transition temperatures as well as in a negative c-axis expansivity below room temperature. The coupling between magnetic orders and dielectric properties below T_N is explained by the lattice strain induced by the magnetoelastic effect. At T_{SR} various physical quantities show discontinuities that are thermodynamically consistent with a first order phase transition

Energy use and CO2 emissions of sweet potato production in Tarlac, Philippines

In this study, the energy use and carbon dioxide (CO2) emission of sweet potato production in Tarlac, Philippines were evaluated. Data were collected from 180 farmers using structured survey questionnaires and face to face interview. Accordingly, the total input and output energy of sweet potato production was 29326.78 and 53885.90 MJ ha-1, respectively. Chemical fertilizers and diesel fuel provided the biggest portion of the total energy consumption in sweet potato production. The energy use efficiency, specific energy and energy productivity was 1.84, 1.95 MJ kg-1 and 0.51 kg MJ-1. Indirect and non-renewable forms of energy dominated the share of the total input energy. The total GHG emission of sweet potato production was 1432.18 kg CO2eq ha-1 (0.095 kg CO2 kg-1). Non-renewable sources of energy such as diesel fuel and chemical fertilizers were the main contributors of GHGs emission at 53.35% and 43.36%, respectively. The use of renewable sources of input energy can lead to lesser GHG emission, more sustainable and environment-friendly agricultural production system for sweet potato. Energy management should be considered as vital strategy for resource conservation, climate protection and to promote sustainable agriculture for sweet potato production
