In 2006, the TOMS shoe company radically disrupted the for-profit business model, literally for good. In challenging what a money-making company could do with its earnings, TOMS incorporated a giving component within its business model, making giving intrinsic to each sale. For every pair of shoes sold, another pair would be given away to a child in need. Giving thus became ‘good business’ at both levels: in making money and in helping kids. The TOMS Effect is a book that explains and explores this phenomenon, through TOMS company history, as well as through major corporations like Walgreens, Walmart, Nestle, Stella Artois, and Michael Kors, as in addition to younger, smaller companies and start-ups like Warby Parker, Brandless, and Not Impossible Labs. TOMS founder Blake Mycoskie was the epitome of counter-culture CEO; his goal to ‘start something that matters’ has been proven in terms of business sense (he is worth $300 million), and has been sustained through product line evolution, and creative marketing, where the shoes become a ‘movement,’ and the customer becomes a ‘partner.’ The TOMS Effect has influenced the behavior of consumers, as well as young entrepreneurs and established corporations. In November 2018, Blake took to late-night shows to publicize TOMS newest giving ventures: End Gun Violence Together (EGVT) and ‘Pick your Style, Pick your Stand.’ These campaigns have been riskier than TOMS’ previous social justice, health, and community efforts. Will this latest iteration of the TOMS model be sustainable, both in terms of monetization of EGVT products, and in effectively causing change?

Literature on the Toms' effect, i.e., greatly increased flow rate of dilute polymer solutions occurring with small increases in solute concentration, is examined. Several existing theories dealing with the phenomena are reviewed, appraised and modified. Work from related fields is analyzed for its applicability to the situation and an effort is made to suggest future lines of study. (Author).

​This book explains theoretical derivations and presents expressions for fluid and convective turbulent flow of mildly elastic fluids in various internal and external flow situations involving different types of geometries, such as the smooth/rough circular pipes, annular ducts, curved tubes, vertical flat plates, and channels. Understanding the methodology of the analyses facilitates appreciation for the rationale used for deriving expressions of parameters relevant to the turbulent flow of mildly elastic fluids. This knowledge serves as a driving force for developing new ideas, investigating new situations, and extending theoretical analyses to other unexplored areas of the rheology of mildly elastic drag reducing fluids.The book suits a range of functions--it can be used to teach elective upper-level undergraduate or graduate courses for chemical engineers, material scientists, mechanical engineers, and polymer scientists; guide researchers unexposed to this alluring and interesting area of drag reduction; and serve as a reference to all who want to explore and expand the areas dealt with in this book.

FROM THE PREFACE The surface modification of polymeric materials has been the object of a large number of investigations, but little attention has been paid to making a polymer surface frictionless or slippery, and lubricating surfaces are practically unmentioned in any books so far published, probably because of the relatively minor importance of polymer friction in industrial applications. A lubricating polymer surface is important, especially in marine and biomedical technologies. For instance, biomaterials to be used for catheterization on the urinary, tracheal, and cardiovascular tracts, or for endoscopy, should have a surface with good handling characteristics when dry and which preferably becomes slippery upon contact with body liquids. Such a low-friction surface must enable easy insertion and removal of the device from a patient. It would further prevent mechanical injury to the mucous membranes and minimize discomfort to the patient. Earlier approaches to providing a low-friction surface were mostly simple applications involving lubricants such as lidocaine jelly, silicone oil, or non-permanent coating with low-friction materials such as polyethylene or fluoroplastics. However, these substances cannot maintain a high degree of slipperiness for the required duration of time, due to the fact that they leach or disperse into the surrounding body fluids. The aim of this book is to describe the principle of lubrication, to outline a variety of methods for attaining a lubricous surface, and to describe the characteristics and properties of such lubricous surfaces. The technology for surface modification of polymers by grafting will find other applications than for lubrication, such as for improvement of the interfacial adhesion in polymer composites.

The Toms effect (drag reduction by introduction of dilute polymer) is investigated analytically in terms of a properly invariant Maxwell model. A stability analysis of plane Poiseuille flow shows stability decreases with increasing elasticity. The change of character of the equations from parabolic to hyperbolic, which arises from introduction of even the slightest amount of elasticity, is shown to lead to dispersive wave phenomenon, whose influence of spreading out localized energy is investigated to obtain indications of explanations of the Toms effect.
