Use Of Social Media

<p>Presently, social media platforms hold an excellent reputation as the closest subject and most comfortable interaction zone inside the learner's heart which makes it the most influential learning tool. However, the evaluation of the social media platforms usage based on student's choices primarily as their collaborative learning supporting tool is still in the small-scale study. Meanwhile, majority of the studies reported so far, focusing more on the usage of a particular type popular or famous social media platforms (e.g., Facebook, YouTube, Twitter and so on) as the collaborative supporting tool. This paper attempt to assess the use of overall social media platforms based on student choices, notably for supporting their collaborative learning activities. A questionnaire survey used for data collection from two universities in two countries. Findings showed that both of the universities’ students have actively utilised their social media platforms as their collaborative supporting tool with 'four times and more' usage over a week, where it is already part of their daily lives. Another result also revealed the students spent their time using social media platforms at least for an hour' in a week as their collaborative supporting tool. Conclusively, it implies that social media platforms are still relevant enough and play an indispensable part in supporting the learning process mainly, for collaborative activity context.</p>

AbstractTerminal Classic circular architecture has been characterized as a “non-Classic” trait stemming from Chontal-Itza groups from the Gulf lowlands who developed a long-distance, circum-peninsular trade route and established their capital city at Chichen Itza in northern Yucatan. Recent investigations of a series of circular shrines proximate to the Caribbean coast in Belize have yielded ceramics and radiocarbon dates that link these buildings to the ninth century, coeval with the early Sotuta phase at Chichen Itza (a.d.830–900). We present an architectural comparison of circular shrines and map out a network of sites that cluster along the rivers and coast of Belize. We consider two possibilities that may not be mutually exclusive: (1) local elite emulation of northern styles following pilgrimage to Chichen Itza for political accession ceremonies, and, (2) trading diasporas involving small-scale migration of Chontal-Itza merchants along the eastern Caribbean coast.

Abstract A short-baseline weather radar network consisting of Ku-band broadband radars (BBR) for meteorological application is under development. The BBR is a short-range and high-resolution Doppler radar for meteorological application, whose range and temporal resolution are several meters and 1 min per volume scan, respectively and coverage is from 50 m to 15 or 20 km. A radar network consisting of BBRs is useful for rapidly and accurately detecting and analyzing small-scale weather phenomena such as localized scattered thunderstorms, tornadoes, and downbursts in locations with a complex topography such as urban or mountainous area. The BBR network project plans to deploy three BBRs in the north Osaka, Japan, area and to observe and analyzing small-scale weather phenomena in detail. At present, two functioning BBRs have been deployed in the Osaka area. This paper presents a description of the BBR network project and its preliminary assessment. Observations of the two-BBR test bed derive expected properties of the three-BBR network, which efficiently covers troposphere in the overlapped area with a minimum observable altitude of tens of meters and a sensitivity of 10.2 dBZ (spatial average at a 5000-km altitude). Integrated reflectivity and preliminary algorithm for multiradar products in the two-BBR test bed, presenting a promising fine structure of precipitation cells, is also shown.

Abstract De Dreu and Gross predict that attackers will have more difficulty winning conflicts than defenders. As their analysis is presumed to capture the dynamics of decentralized conflict, we consider how their framework compares with ethnographic evidence from small-scale societies, as well as chimpanzee patterns of intergroup conflict. In these contexts, attackers have significantly more success in conflict than predicted by De Dreu and Gross's model. We discuss the possible reasons for this disparity.

We highlight here the results from our studies of the morphology and dynamical evolution of CME structures in the solar corona using two instruments on board SOHO: LASCO and EIT.

A new family of scanning probe microscopes has emerged that is opening new horizons for investigating the fine structure of matter. The earliest and best known of these instruments is the scanning tunneling microscope (STM). First published in 1982, the STM earned the 1986 Nobel Prize in Physics for two of its inventors, G. Binnig and H. Rohrer. They shared the prize with E. Ruska for his work that had led to the development of the transmission electron microscope half a century earlier. It seems appropriate that the award embodied this particular blend of the old and the new because it demonstrated to the world a long overdue respect for the enormous contributions electron microscopy has made to the understanding of matter, and at the same time it signalled the dawn of a new age in microscopy. What we are seeing is a revolution in microscopy and a redefinition of the concept of a microscope.Several kinds of scanning probe microscopes now exist, and the number is increasing. What they share in common is a small probe that is scanned over the surface of a specimen and measures a physical property on a very small scale, at or near the surface. Scanning probes can measure temperature, magnetic fields, tunneling currents, voltage, force, and ion currents, among others.

It is now well established that the phase transformation behavior of YBa2Cu3O6+δ is significantly influenced by matrix strain effects, as evidenced by the formation of accommodation twins, the occurrence of diffuse scattering in diffraction patterns, the appearance of tweed contrast in electron micrographs, and the generation of displacive modulation superstructures, all of which have been successfully modeled via simple Monte Carlo simulations. The model is based upon a static lattice formulation with two types of excitations, one of which is a change in oxygen occupancy, and the other a small displacement of both the copper and oxygen sublattices. Results of these simulations show that a displacive superstructure forms very rapidly in a morphology of finely textured domains, followed by domain growth and a more sharply defined modulation wavelength, ultimately evolving into a strong <110> tweed with 5 nm to 7 nm period. What is new about these findings is the revelation that both the small-scale deformation superstructures and coarser tweed morphologies can result from displacive modulations in ordered YBa2Cu3O6+δ and need not be restricted to domain coarsening of the disordered phase. Figures 1 and 2 show a representative image and diffraction pattern for fully-ordered (δ = 1) YBa2Cu3O6+δ associated with a long-period <110> modulation.
