The construction and use of belief in cognitive therapy : a discursive analysis : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University

This research explores how the notion of belief is constructed and used within the cognitive therapy domain. Utilising a multi-media approach, in which cognitive therapy texts were gathered from instructional books, demonstration videos, and interviews with practicing psychotherapists, the transcripts were analysed using Jonathan Potter, Derek Edwards and Margaret Wetherell's model of discourse analysis. The analytic attention was on the linguistic resources and practices therapists had available and used in constructing and deploying different notions of belief. By approaching therapists' belief talk in this way and showing the contingent, socially constructed, and rhetorical nature of their discourse use, two main constructions of belief became evident. These were of 'a belief itself' and of 'a believing person'. In addition, Davies and Harrés' positioning theory was utilised which highlighted two main subject positions; the therapist as the 'expert' and the client as the 'layperson'. The findings tend to support the view that there are medium and therapist specific idiosyncratic aspects to belief, which are constructed and constituted in multiple repertoires and by various discursive strategies. This suggests a need for cognitive therapy to re-evaluate the notion of belief and its various uses, and highlights the benefits and pitfall of utilising a multi-media discursive approach

Neutrinos from Off-Shell Final States and the Indirect Detection of Dark Matter

We revisit the annihilation of dark matter to neutrinos in the Sun near the WW and tt kinematic thresholds. We investigate the potential importance of annihilation to WW* in a minimal dark matter model in which a Majorana singlet is mixed with a vector-like electroweak doublet, but many results generalize to other models of weakly-interacting dark matter. We re-evaluate the indirect detection constraints on this model and find that, once all annihilation channels are properly taken into account, the most stringent constraints on spin-dependent scattering for dark matter mass 60 GeV < mX < mt are derived from the results of the Super-Kamiokande experiment. Moreover, we establish the model-independent statement that Majorana dark matter whose thermal relic abundance and neutrino signals are both controlled by annihilation via an s-channel Z boson is excluded for 70 GeV < mX < mW. In some models, annihilation to tt* can affect indirect detection, notably by competing with annihilation to gauge boson final states and thereby weakening neutrino signals. However, in the minimal model, this final state is largely negligible, only allowing dark matter with mass a few GeV below the top quark mass to evade exclusion.Comment: 22 pages, 5 figure

The Cost of the Death Penalty in Maryland

Analyzes 1,136 capital cases between 1978 and 1999 to estimate the total costs to the state's taxpayers (i.e., prison and adjudication costs for the duration of the case) when the death penalty is sought compared to when it is not

A Prehistory of n-Categorical Physics

This paper traces the growing role of categories and n-categories in physics, starting with groups and their role in relativity, and leading up to more sophisticated concepts which manifest themselves in Feynman diagrams, spin networks, string theory, loop quantum gravity, and topological quantum field theory. Our chronology ends around 2000, with just a taste of later developments such as open-closed topological string theory, the categorification of quantum groups, Khovanov homology, and Lurie's work on the classification of topological quantum field theories.Comment: 129 pages, 8 eps figure

The Contribution of Chinese FDI to Africa’s Pre Crisis Growth Surge

In the 3 years before the 2008 Financial Crisis, GDP growth in sub Saharan Africa (averaged over individual economies) was around 6%, or 2 percentage points above mean growth rates for the preceding 10 years. This period also coincided with significant Chinese FDI flows into these countries, accounting for up to 10% of total inward FDI flows for certain countries in these years. We use growth accounting methods to assess what portion of this elevated growth can be attributed to Chinese inward FDI. We follow Solow (1957), Dennison (1962), and others and use data for individual economies between 1990 and 2008 to calculate Solow residuals for these years for individual economies. We use capital stock data, workforce, and factor share data by country. Capital stock data is unavailable directly, and so we use perpetual inventory methods to construct the data. Factor shares come from UN National Accounts data. We then run counterfactual growth accounting experiments for thirteen Sub-Saharan African countries excluding Chinese FDI inflows for 2005-2007 and also 2003-2009. Our individual results vary by year and country, but there are several year/country combinations where Chinese FDI contributed to an additional one half of a percentage point or above to GDP growth. These results suggest that a significant, even if in some cases small, portion of the elevated growth in sub Saharan Africa in the three years before the Financial Crisis and also in the two years afterwards (2008-2009) can be attributed to Chinese inward investment.

Informational Intermediation and Competing Auctions

We examine the effects of provision of information about seller qualities by a third-party in a directed search model with heterogeneous sellers, asymmetric information, and where prices are determined ex post. The third party separates sellers into quality-differentiated groups and provides this information to some or all buyers. We show that this always raises total welfare, even if it causes the informed buyers not to trade with low quality sellers. However, buyers and some sellers may be made worse off in equilibrium. We also examine the provision of information by a profit maximizing monopoly, and show that it may have an incentive to overinvest in the creation of information relative to the social optimum.

Simple Reputation Systems

This paper develops a model of simple 'reputation systems' that monitor and publish information about the behavior of sellers in a market with search frictions and asymmetric information. The reputations created by these systems influence the equilibrium search patterns of buyers and thus provide for market-based 'punishment' of bad behavior. Our model allows us to determine the effects of the introduction of a reputation system on the behavior and welfare of buyers and sellers in such a market. We show that a simple reputation system that rewards honesty can enhance welfare by allowing good sellers to truthfully signal their type. However, we also show that in some cases the same reputation system is prone to strategic manipulation by sellers who always have low quality products. In this case, we show that an alternative simple reputation system that screens for type can be superior

The Value of a Reputation System

This paper explores the trade-off between the short-term benefits of false quality advertisements against the longer term costs of reputation damage. A directed search model is constructed in which submarkets are created by the advertisements and reputations of sellers. A reputation system links misleading advertisements in the present period to a lower reputation in the next period. We show that a reputation system always increases the prices of high quality products and directs search more accurately towards the sellers with such products. We also show that buyers are hurt by a reputation system if the market is thin -- has few sellers -- because the equilibrium increase in prices is greater than the equilibrium increase in the quality of trade. Finally, we show that a reputation system which screens for honesty increases social welfare by making sellers more truthful. However, we also show that a reputation for honesty is not always highly valued and that an alternative reputation system which screens for type can be more effective.reputation systems, directed search
