Victorious in its previous campaigns in Africa against native armies, Britain now confronted an altogether different foe. The Boers proved to be formidable opponents, masterfully compensating for inferior numbers with grim determination, resourcefulness and strong religious faith. Their mobility, expert use of cover, and knowledge of the terrain, in which they employed powerful long-range magazine rifles, gave them initial advantages. By contrast the British suffered from inadequate transport, insufficient mounted troops and poor intelligence. Despite marshalling the immense resources of their empire, the British were to be severely tested in a war which one general described as ‘the graveyard of many a soldier’s reputation’.

Proportional Representation
The book offers a rigorous description of the procedures that proportional representation systems use to translate vote counts into seat numbers. Since the methodological analysis is guided by practical needs, plenty of empirical instances are provided and reviewed to motivate the development, and to illustrate the results. Concrete examples, like the 2009 elections to the European Parliament in each of the 27 Member States and the 2013 election to the German Bundestag, are analyzed in full detail. The level of mathematical exposition, as well as the relation to political sciences and constitutional jurisprudence makes this book suitable for special graduate courses and seminars.

Library Data
Numerical evidence is everywhere and how best to handle and leverage it is a growing concern in the academic world in general and the academic library world in particular. Libraries are not only storehouses and key contacts for library patrons in accessing numbers, but are also collectors and users of their own data, which is integral to the functioning of the library itself.

The Bees of the World
In this extensive update of his definitive reference, Charles D. Michener reveals a diverse fauna that numbers more than 17,000 species and ranges from the common honeybee to rare bees that feed on the pollen of a single type of plant. With many new facts, reclassifications, and revisions, the second edition of The Bees of the World provides the most comprehensive treatment of the 1,200 genera and subgenera of the Apiformes. Included are hundreds of updated citations to work published since the appearance of the first edition and a new set of plates of fossil bees.

The Source
‘Why do I feel so tired and drained?’ You’re not alone if you’re constantly asking yourself this question. Exhaustion is epidemic in America and ‘lack of energy’ one of the top five complaints to doctors nationwide. This is because vast numbers of people have lost their connection with the inner energy that is the source of healing and radiant vitality.

Fuzzy Probabilities New Approach and Applications
In probability and statistics we often have to estimate probabilities and parameters in probability distributions using a random sample. Instead of using a point estimate calculated from the data we propose using fuzzy numbers which are constructed from a set of confidence intervals. In probability calculations we apply constrained fuzzy arithmetic because probabilities must add to one. Fuzzy random variables have fuzzy distributions. A fuzzy normal random variable has the normal distribution with fuzzy number mean and variance. Applications are to queuing theory, Markov chains, inventory control, decision theory and reliability theory.
A Frozen Hell
This is a book of battles — savagely fought, often with great heroism on both sides, under brutal, subarctic conditions. Guerrillas on skis, heroic single-handed attacks on tanks, unfathomable endurance, and the charismatic leadership of one of this century’s true military geniuses — these were the elements of Finland’s short-lived victory. For all the epic resistance of the Finns, the outcome was foreordained. Belatedly the Russians realized that an expected easy triumph over a vastly outnumbered foe had become a slaughterhouse. Incompetent commanders were replaced, more and better troops were moved into position, and orders were given to overwhelm and crush the Finns by the sheer weight of massed numbers. But even though they lost on the battlefield, the Finns’ pointed resistance kept the Iron Curtain from drawing closed around their land and allowed Finland to remain free, even as other countries fell one by one.
