The module provides a first introduction to abstract ideas of differential geometry of curves and surfaces, with some elements of knot theory and hyperbolic geometry. Building on experience with vectors in three dimensions and elementary calculus, the modules asks what one can say of mathematical interest about an arbitrary curve or surfaces. The module starts with the problem of how to tell if a curve or piece of string is knotted (other than by pulling it about, ie. mathematically) before moving on to differential geometric (calculus based) methods of measuring properties such as 'torsion' and 'curvature' of a curve or surface. The module ends with exposure to more abstract hyperbolic surfaces and higher-dimensional spaces defined by identifications and symmetries. There will be some proofs.

measure and maximise them. It should include:
a) An explanation of revenue/yield management (ref. 4.1).
b) An analysis of sales techniques used to promote and maximise revenue (ref. 4.2).
c) An evaluation of the usage of forecasting and statistical data in the room division (ref 4.3).
d) A description with calculation of performance indicators used to measure the success of accommodation sales (ref 4.4).
The case scenario is as follow:
The Five Seasons hotel located in Winchester has the following room breakdown for May
Rooms Beds Occupancy
75 single rooms = 75 55 occupied
60 Twin rooms = 120 50 occupied by two people, 5 occupied by one person
80 Double rooms = 160 30 occupied by two people, 40 occupied by one person
Total 215 Rooms 355 180 rooms let (260 sleepers)
Fredrickson advances a new theory describing the form and function of joy, interest, contentment, and love. In her new approach, she rejects two former common assumptions about emotion: "I propose discarding two key presumptions. The first is the presumption that emotions must necessarily yield specific action tendencies" . . . and "that emotions must necessarily spark tendencies for action. Some positive emotions seem instead to spark changes primarily in cognitive activity, with changes in physical activity (if any) following from these cognitive changes" (Fredrickson, 1998, p. 303). "So, in place of action tendencies, I propose speaking of " (Fredrickson, 1998, p. 303). Whereas negative emotions narrow a person's momentary thought–action repertoire, positive emotions broaden this repertoire. Thus, positive emotions "prompt individuals to discard time–tested or automatic (everyday) behavioral scripts and to pursue novel, creative, and often unscripted paths of thought and action" (Fredrickson, 1998, p. 304). Fredrickson's new paradigm also may explain how positive emotions may act to regulate negative emotions.

A high yield is desirable, but is not the whole story. The reaction once used to manufacture phenol from benzene generates 1 mole of sodium sulphite (126g), for every mole of phenol (88g) produced. This may be acceptable if there is sufficient demand for the sodium sulphite, but if not, it presents a serious waste management problem, and adds significantly to costs.
It is much better to reduce the amount of waste generated in the first place, rather than treat it at a later date, and this is an important aim of green chemistry. A yield calculation does not indicate how efficiently the reactants have been used in generating the desired product, and so does not indicate how effectively waste is being reduced.

"Seligman and Csikszentmihalyi (2000) and Peterson and Seligman (2004) argued that their reasoning, and their prescriptions for happiness and well–being, are based on empirical evidence, obtained via a strict adherence to the positivist scientific method, which is presumed to provide a high degree of transparency. 'What seemed to be lacking, however, was a vision that justified the attitude and the methodology. I was looking for a scientific approach to human behavior, but I never dreamed that this could yield a value–free understanding' (Seligman & Csikszentmihalyi, 2000, p. 7). Far from 'yielding a value–free understanding,' positive psychology has unwittingly tied itself to a neo–liberal economic and political discourse, as can be seen from Seligman and Csikszentmihalyi (2000) and Peterson and Seligman's (2004) prescriptions, which are underpinned by a philosophy based on responsibility, moderation, and work ethic, all essential values for the effective operation of a neo–liberal economy" (McDonald & O'Callaghan, 2008, 138).

Given the scores and class/category assignments for any individual are generated via fixed computer algorithm, then, given a fixed set of inputs, the same scores and assignments will always be generated. The assessment thus has perfect reliability. So, any ‘unreliability’ is actually associated with the unique performance output of an individual on the CPP (Lumsden (1978) had already set out this proposition many years ago in connection with other kinds of questionnaire assessments). Given the assessment cannot validly be redone within a short period of time, retest reliability cannot adequately be established except perhaps over intervening periods of four years or more (to ensure that the task contents and requirements are largely forgotten). However, a number of these studies have nevertheless been undertaken. The reliability of assessment is thus solely a function of ‘person reliability’. If cognition within individuals is inherently unstable, then no assessment can yield reliable stationary estimates of attributes considered definitive of that cognition.
