This edited volume provides an in-depth exploration of a theoretical framework supporting Early Childhood Science Education research and teaching best practices. Particularly by presenting the concept of the Precursor Model from an epistemological, psychological, and didactical point of view at Early Childhood Science Education. The book examines and discusses the nature of Precursor Models and their use for early science teaching and learning. It scrutinizes different aspects of the construction of such models applied in early childhood education settings and contexts. Several empirical studies are presented within diverse scientific domains, as well as in international educational contexts. By providing a vary of examples of precursor models it makes this book a great companion for teachers aiming to teach children to understand and reason about topics such as: floating and sinking; shadow formation; water state changes; air; clouds and rain; electricity; inheritance and selection; as well as variation within populations. Finally, this volume supports the development of science education from an early age by using the original framework of a precursor model to mediate teaching and learning science at school during early childhood.

Seismology has come a long way. Being the scientific study of seismic waves and their allied phenomena, it has entered a multidisciplinary realm. As the main tool, it provides a wealth of information when applied systematically to dig inside the Earth structure. Notwithstanding, the utility of seismic waves has increased manifold. Starting from knowing the epicenter of seismic events, it has influenced mapping of civil engineering structures such as dams and bridges, as well as huge constructions. Although there is no dearth of technical papers in the area of seismic waves, there is an absence of synchronized and recent coherent contents in the direction of seismic waves. The book will be a unique contribution to the field of seismology, with the aim of assimilating theory and practices. It will provide a comprehensive glimpse of recent advancements in this area with a strong unification of theory and practices. The main objective of the book is to present an in-depth analysis of the theory and real implementations of seismic waves as versatile probes that would be integrated with modern and future perspectives. The current and the future strategies to be discussed in the relevant areas of seismic waves will be another boon for readers. This book will cater to the needs of novices, researchers and practitioners. Additionally, the contents of the book will be useful for undergraduate as well as postgraduate students of earth science disciplines.

In February 2010, the National Research Council convened a workshop to investigate the feasibility of developing well-grounded common metrics to advance behavioral and social science research, both in terms of advancing the development of theory and increasing the utility of research for policy and practice. The Workshop on Advancing Social Science Theory: The Importance of Common Metrics had three goals: To examine the benefits and costs involved in moving from metric diversity to greater standardization, both in terms of advancing the development of theory and increasing the utility of research for policy and practice. To consider whether a set of criteria can be developed for understanding when the measurement of a particular construct is ready to be standardized. To explore how the research community can foster a move toward standardization when it appears warranted. This book is a summary of the two days of presentations and discussions that took place during the workshop.

In this thesis, the pseudogap and the precursor superconducting state, which are of great importance in clarifying the superconductivity mechanism in high-temperature cuprate superconductors, are investigated with a c-axis optical study in YBa2(Cu1-xZnx)3Oy. Testing was performed over a wide energy range with smaller temperature intervals for several Zn-substituted samples, as well as for several carrier-doping levels. A spectral weight (SW) analysis, in which the pseudogap behavior can be separated from the superconducting condensate with the SW transfer to the high-energy region, revealed that the pseudogap is not the precursor of the superconductivity (carriers moving to the high-energy region with pseudogap opening never contribute to the superconducting condensation). Moreover, the high-energy transfer continues even below Tc for the Zn-substituted samples (in which we weaken the superconductivity), which gives evidence to the coexistence of the pseudogap and the superconducting gap below Tc. On the other hand, the analysis of optical conductivity revealed that a precursor state to superconductivity can be defined at temperatures much higher than Tc. The superconducting carrier density (ns) was calculated for each temperature (above and below Tc) and the results confirmed the existence of ns at temperatures above Tc. The observed real superconducting condensate (ns) above Tc puts a serious constraint on the theory for high- Tc superconductivity. A theory based on an inhomogeneous superconducting state, in which a microscopically phase-separated state in a doped Mott insulator can be observed, is the most plausible candidate. This theory can explain the existence of ns and the observed temperature range for the precursor superconducting state. The results obtained show that the pseudogap coexists with superconductivity below Tc and is not the precursor of superconductivity. On the other hand, it is also possible to define a precursor superconducting state that is different than the pseudogap. The temperature range and the observed superconducting condensate in this state can be explained with the help of the inhomogeneous superconducting state.

One of the greatest of seers, an apex personality in the history of mankind who ascended to the crest of the universal forces to eliminate the poignancy of human ignorance on earth. He made a God’s Labour with great adventure to free man from the shackles of the iron rules of imposed destiny. He had to make a supreme sacrifice to change the destiny of mankind by rendering his own earthly body as a base for the descent of the highest Truth, Power, Light, Force and Consciousness onto the earth for a luminous future of mankind. He fulfilled his ultimate dream of liberating humanity from the vicious circle of ignorance and inconscience. The Saviour of mankind is none other than Sri Aurobindo, who has achieved all for humanity and charted the pathway for humanity to a delightful, glorious New World and New divine Race.... In the upheaval of humanity’s evolutionary journey, Sri Aurobindo has explored and prepared a path for mankind leading to a world of Beauty and Love. We must follow that path to find that divine life where there would be no disease, decay, death, or destruction. Life would no longer be a confusion and chaos, a struggle for basic survival; there would be no quarrels, fighting, competition; there would be no war, accidents, calamities; there would be no more selfishness, ego-eccentric attitudes, ingratitude, inhumanity, cruelty, poverty, suffering or pain; there would be no medical emergencies, heinous killing and murder, barbarism, vandalism....
