This is a true story about a shop steward who had 83 grievances with his employer over a 14 month period. By doing his best as a shop steward, he ended up with 57 personal grievances and was threatened with the sack 8 times and was actually sacked twice. The Trade Unions District Audit were informed of these problems though they seemed to decide to protect the employer rather than their union member. Solicitors and barristers were subsequently involved however time passed and this led to time running out for a potential claim. The issues were put into court which, in the opinion of the author, led to rough justice.
This text, now in its second edition, offers an up-to-date, expanded treatment of the behaviour of polymers with regard to material variables and test and use conditions. It highlights general principles, useful empirical rules and practical equations.;Detailing the specific behaviour of many common polymers, the text: places emphasis on time and frequency dependence over temperature dependence; uses contemporary molecular mechanisms to explain creep, stress relaxation, constant strain rate responses and crazing; provides explicit equations to predict responses; supplies a discussion of large deformation multiaxial responses; compares statistical and continuum theories on the same data set; and updates stress-strain behaviour and particulate filled systems.

Conflict is both a timely and a timeless challenge in schools, stymying school reform initiatives and elevating administrators’ job stress. If “school is a family,” as many claim, it is often a dysfunctional one. Relationships between and among staff, parents, community and school boards may be destructively divisive, or alternatively, schools may avoid addressing controversial issues like inequity, fearful of tensions that would be unleashed. From Conflict to Collaboration: A School Leader’s Guide to Unleashing Conflict’s Problem Solving Power offers a novel perspective. Rather than impeding school reform, school leaders may harness conflict to spark organizational vitality and growth. Honoring diverse viewpoints enables savvy school leaders to engage stakeholders in meaningful collaboration that builds capacity, enshrines productive dialogue and group problem-solving as cornerstones of school culture, and energizes the school community. Drawing on knowledge from the fields of education, engineering, psychology and business, the book offers an on-the-job guide for present and future school leaders. Dozens of actionable leadership strategies are highlighted; case studies illustrate key concepts; and probing questions for school leaders and school improvement teams follow each chapter. In a step-by-step process, the book demonstrates how the techniques of design thinking may be applied to build a school’s “conflict agility.”
The advent of high-speed computers has made it possible for the first time to calculate values from models accurately and rapidly. Researchers and engineers thus have a crucial means of using numerical results to modify and adapt arguments and experiments along the way. Every facet of technical and industrial activity has been affected by these developments. The objective of the present work is to compile the mathematical knowledge required by researchers in mechanics, physics, engineering, chemistry and other branches of application of mathematics for the theoretical and numerical resolution of physical models on computers. Since the publication in 1924 of the "Methoden der mathematischen Physik" by Courant and Hilbert, there has been no other comprehensive and up-to-date publication presenting the mathematical tools needed in applications of mathematics in directly implementable form.

Although over 40 years have passed since Jacobs (1945) convincingly established the basic radial pattern of residual growth stress in growing trees, yet this phenomenon is still not widely appreciated in wood science and technology circles. This is in spite of the fact that the presence of these stresses of sizeable magnitudes has long been recognized as a primary cause of shakes and splits in logs as well as the warping of lumber sawn in the green condition. The presentation of the subject of growth stresses in trees presents some special problems due to the wide range of specialists who potentially might have an interest in the subject. For example, tree physiologists interested in questions such as the relation of mechanical stress to stem taper and the role of reaction wood and gravity forces in determining tree crown form encounter growth stress models. Silvi culturists interested in the relation ofthinning practices to wood quality find that wood properties are correlated with growth stress levels which are in turn significantly changed by cutting practices. Wood techno logists interested in the relation of residual growth stress gradients in green logs to the dimensional quality of sawn and seasoned lumber are forced to take a more quantitative approach to the effect of growth stresses than might have been the case in the past.
The field of ferroelectricity has greatly expanded and changed in recent times. In addition to classical organic and inorganic ferroelectrics, new fields and materials, unknown or inactive 20 to 40 years ago, have appeared. They are important for both basic science and applications, and show technological promise for novel multifunctional devices. New fields include multiferroic magnetoelectric systems, where spontaneous polarization and spontaneous magnetization are allowed to coexist; incommensurate ferroelectrics, where the periodicity of the order parameter is incommensurate to the periodicity of the underlying basic crystal lattice; ferroelectric liquid crystals; dipolar glasses; relaxor ferroelectrics; ferroelectric thin films; nanoferroelectrics. These new fields are not only of basic physical interest, but also of great technological importance, allowing the design of new memory devices, spintronic applications, and the design of electro-optic devices. They are also important for applications in acoustics, robotics, telecommunications and medicine. The book is primarily intended for material scientists working in research or industry. It is also intended for graduate and doctoral students and can be used as a textbook in graduate courses. Finally, it should be useful for anybody interested in following the developments in modern solid state physics.

Areader who achieves a substantial command of the material con tained in this book should be able to read with understanding most of the literature in the field. Possible exceptions may be certain special aspects of the subject such as the aeroelasticity of plates and sheIls or the use of electronic feedback control to modify aeroelastic behavior. The first author has considered the former topic in aseparate volume. The latter topic is also deserving of aseparate volume. In the first portion of the book the basic physical phenomena of divergence, control surface eflectiveness, flutter and gust response of aeronautical vehicles are treated. As an indication of the expanding scope of the field, representative examples are also drawn from the non aeronautical literature. To aid the student who is encountering these phenomena for the first time, each is introduced in the context of a simple physical model and then reconsidered systematicaIly in more compli cated models using more sophisticated mathematics.
