This classic text on multiple regression is noted for its nonmathematical, applied, and data-analytic approach. Readers profit from its verbal-conceptual exposition and frequent use of examples. The applied emphasis provides clear illustrations of the principles and provides worked examples of the types of applications that are possible. Researchers learn how to specify regression models that directly address their research questions. An overview of the fundamental ideas of multiple regression and a review of bivariate correlation and regression and other elementary statistical concepts provide a strong foundation for understanding the rest of the text. The third edition features an increased emphasis on graphics and the use of confidence intervals and effect size measures, and an accompanying CD with data for most of the numerical examples along with the computer code for SPSS, SAS, and SYSTAT. Applied Multiple Regression serves as both a textbook for graduate students and as a reference tool for researchers in psychology, education, health sciences, communications, business, sociology, political science, anthropology, and economics. An introductory knowledge of statistics is required. Self-standing chapters minimize the need for researchers to refer to previous chapters.
In this example, as may be judged from its mean and sd (Table 8.5.1), it would
signify a very low (possibly the lowest possible) level of motivation, so these
contrasts imply significantly higher performance for the control group than the
average of the experimental groups when motivation is very low. In summary, the
analysis indicates markedly different (linear) relationships between level of
motivation and performance as a function of instructions. The two experimental
groups show ...

Consider as an example how ability (X) and motivation (Z) impact achievement in
graduate school (Y). One possibility is that their effects are additive. The
combined impact of ability and motivation on achievement equals the sum of their
separate effects; there is no interaction between X and Z. We might say that the
whole equals the sum of the parts. A second alternative is that ability and
motivation may interact synergistically, such that graduate students with both high
ability and high ...
Among the many diverse aspects of environmental science, none is more critical to the future of society and nature than water. Understanding the role of water on Earth and making good decisions regarding water conservation and hydrological hazards depends on learning the fundamentals of physical hydrology. This textbook, now in an expanded second edition, provides the clearest opportunity for students to absorb those fundamentals. Written at an introductory level, Elements of Physical Hydrology covers virtually every aspect of this subject, including: • The hydrological cycle• Water budgets at catchment to global scales • Spatial and temporal aspects of precipitation• Evapotranspiration• Fluid dynamics and the Bernoulli equation• Laminar and turbulent flows• Open channel flow • Flood movement through reservoirs and channels • Flood frequency analysis• Groundwater flow• Aquifer characterization• Land subsidence• Soil moisture dynamics• Flow in the unsaturated zone• Hydrologic controls on vegetation • Biotic controls on hydrological processes• Runoff generation from surface and subsurface sources• Catchment models• The water-food-energy nexus• The globalization of water• Impacts of changing climate Layering one topic upon the next, Elements of Physical Hydrology succeeds in moving from simple, easy-to-grasp explanations through equations and models in a manner that will leave students new to the topic eager to apply their knowledge. Professionals in related disciplines will also find this book ideal for self-study. Thoughtfully illustrated, carefully written, and covering a broad spectrum of topics, this classic text clarifies a subject that is often misunderstood and oversimplified.
Water also has the greatest specific heat capacity and latent heat of vaporization
known among liquids, and has a higher thermal conductivity than any other liquid
except mercury. It also has a high heat of fusion. One consequence of these
properties is that water at the Earth's surface tends to moderate effects of hot or
cold air temperatures. Water Density and Viscosity Liquid water contracts as it
cools, reaching a maximum density (ρ) of 1000kg m−3 at 3.98°C (Figure A2.1;
Table A2.1) ...
This book tests the hypothesis that Roman law was a formative influence on Islamic law.
This chapter is intended for the non-specialist who wishes to acquire some
familiarity with the nature of Islamic law before proceeding to the argument
presented in this book. The specialist reader can go straight to the chapter on
wala ' . (a) Immutability Islamic law is a divine law elaborated and transmitted by
private scholars. Whatever the degree to which it had been controlled by caliphs
in earlier times, law-finding had ceased to be a caliphal prerogative by late
Umayyad times, and ...
This Handbook is designed to help cooperative education and internship professionals and employers design, carry out, and disseminate quality research and evaluation studies of work-based education. It offers examples of current, leading-edge studies about work-based education, but with a practical twist: The chapter authors frame their studies within a specific key research design issue, including finding a starting point and a theoretical framework; fitting research into one's busy practitioner workload; deciding on particular data-gathering methods and an overall methodological approach; integrating qualitative and quantitative methodologies; and disseminating results. Also addressed are questions and concerns that are relevant throughout the course of a research project: the use of theory in research; the role and relationship of program assessment to research; and ethical considerations in research. By combining descriptions of exemplary research and evaluation studies with practical advice from top researchers in the field, this volume is a useful tool for educators and employers who are designing and carrying out their own studies, as well as a resource for what current research is discovering and affirming about the field itself. Educators from other fields, such as study abroad and service-learning will also find this book an indispensable reference in conducting research on experiential learning and teaching.
Most importantly my role as placement coordinator to biology students meant that
I had to exclude these from the project as I could be viewed as examiner by some
of these students, which might have influenced what they would tell me about
their learning. Secondly, I had to make my intentions very clear to the participants
in the project, get their informed consent, and assure them of the confidentiality of
our interviews. This involved the approval of an ethics proposal by the
University's ...
