A note on Nuba Mountain verb extensions

Based on the available literature and personal communications with specialists, this paper surveys the rich occurrence of verb extensions in the Nuba mountain languages which mark different grammatical functions such as causative, dative and locative applicatives, comparative, passive, antipassive, reciprocal/reflexive, and associative/instrumental, as well as ventive, itive, habitual, iterative and pluractional marking. Given the diversity of forms among the different groups in the area, a set of guidelines is considered to determine whether specific extensions can be reconstructed or are recent innovations. An extensive table is provided which provides the forms of the reported extensions and compares them with those reconstructed in specific subbranches of Niger-Congo, Nilo-Saharan, Afro-Asiatic, and in Khoe.

Data—too good to be true?

A simple and extensive table that contains an error, reducing the analysis to nonsense.

Determinants of Sustainable Consumption Behaviour

This study reviewed 82 empirical articles on sustainable consumption published during 1997 to 2014. The review explored different factors affecting sustainable consumption decision-making. The factors were categorized as personal, behavioural and socio-cultural. A taxonomic synopsis of the findings is presented in an extensive table. The paper identifies various prevalent motives, facilitators and barriers affecting sustainable consumption decision-making and provides possible explanations for inconsistencies observed in consumers' sustainable consumption behaviour. A conceptual framework is proposed that considers various motives, attitudes and barriers and explains how they are related to sustainable consumption behaviour.

A Useful Old Theorem

Claudius Ptolemy (second century A.D.) was one of the pioneers of trigonometry as well as a major contributor to astronomy, geography, and even astrology. His principal work. Mathematical Syntaxis, known generally as Almagest*, contained an extensive table of lengths of chords in a circle in terms of the angles subtended by the chords.

Leech roots and Vinberg groups

We study the recently defined Leech roots, which have many remarkable properties. They are the fundamental roots for the even unimodular lattice in Lorentzian space R 25,1 , and correspond one for one with the points of the Leech lattice. The paper contains an extensive table of the Leech roots in both Euclidean and hyperbolic coordinates. We provide the first of what promise to be many applications by showing that the Leech roots simplify and explain the remarkable results of Vinberg and Kaplinskaja on the reflexion groups of unimodular Lorentzian lattices in dimensions below 20. They also enable us to make some progress on the study of these groups in the next few dimensions.

On a Table for the Formation of Logarithms and Anti-Logarithms to Twelve Places (Part III)

The twelve-figure table which accompanied Part I. was extracted from a table extending to twenty-four places, which is still in manuscript. Hence the details I am about to give of the methods of construction and verification made use of, will necessarily have reference to the more extensive table.

XII.—Experiments on the modulus of torsion

Numerous experiments have already been published on the strength of wood and other substances, as far as regards their cohesion and elasticity; but I am not aware of any extensive table of the modulus of torsion of different species of wood, deduced from experiments conducted upon a proper scale, and with the necessary care. To supply this defect, and to furnish the practical engineer and mechanic with useful data, and with rules for their application, is the object of the pre­sent communication, consisting of a copious table of the results of my experi­ments, made at various times, and upon substances of considerable variety of dimensions within the ordinary limits of practice.
