Origins of inflated responsibility in obsessive compulsive disorder

The pivotal role of inflated responsibility beliefs in the maintenance and treatment of obsessive-compulsive disorder (OCD) has been clearly demonstrated (Rachman, 1993; Salkovskis, 1998; Shafran, 1997; van Oppen & Arntz, 1994). Yet little is known about the origins of these beliefs, their contribution to a sense of inflated responsibility or the symptoms of OCD, or the contribution of personality to inflated responsibility and to OCD, The aims of this thesis were to investigate a model of the inter-relationships among the personality dimensions of neuroticism and psychoticism, inflated responsibility and OCD, and the origins of inflated responsibility to inflated responsibility and to OCD. In order to achieve these aims, a scale was developed to assess the origins of inflated responsibility based upon the five pathways proposed by Salkovskis, Shafran, Rachman, and Freeston (1999) and the additional domains of guilt, vigilance and thought-action fusion (Shafran, Thordarson, & Rachman, 1996; Shafran, Watkins & Charman, 1996; Tallis, 1994). Eighty-four participants with OCD (age M = 43.36) and 74 control participants (age M =37.14) volunteered to participate in the two studies of this thesis. The aim of Study 1 was to develop and validate a measure of the Origins of Inflated Responsibility (OIR). The results of the first study yielded a 25-ttem scale, the Origins of Inflated Responsibility Questionnaire (OIRQ) with five independent factors: responsibility, strictness, protection from responsibility, critical incidents, and peer blame which demonstrated both internal reliability and temporal stability over a 2-week period. In Study 2, participants also completed the Responsibility Attitudes Scale (Salkovskis, Wroe, Gledhill, Morrison, Forrester, Richards, ct al. (2000) (a measure of inflated responsibility), the Padua Inventory (Sanavio, 1988) (to measure of the symptoms of OCD)y and the Eysenck Personality Inventory-Revised (Eysenck & Eysenck, 1991). Multivariatc Analysis of Variance revealed that the OCD group scored higher on all variables than the control group except for strictness where the groups were not different, and psychoticism where the OCD group scored lower. A series of Multiple Regression analyses revealed that both group and the OIR contributed to inflated responsibility (R2 = .56). When all variables, OIR, inflated responsibility and neuroticism were entered as predictors of OCD, 60% of the variance in OCD was explained however, 49% of the variance was shared by the independent variables suggesting the presence of some underlying construct. Structural Equation Modelling, where all the constructs in the model were examined simultaneously, revealed that neuroticism contributed to the OIR, inflated responsibility and OCD. The OIR were also significant predictors of inflated responsibility and indirectly through inflated responsibility predictive of OCD. The OIR also directly predicted OCD and when the total effects are considered, their contribution was greater than the total effect for inflated responsibility alone. The results of these studies provide good support for the origins of inflated responsibility proposed by Salkovskis et al. (1999), as measured by the OIRQ developed for use in the current thesis. The results also support the contribution of inflated responsibility and neuroticism, as well as the OIR, to OCD, The large amount of variance shared by the OIR, inflated responsibility and neuroticism suggest that there might be some underlying construct, perhaps of a biopsychosocial nature, that requires further investigation for its role in the onset and maintenance of OCD. The clinical relevance of these findings is discussed in terms of early prevention strategies and interventions.

An investigation into the origins of the British romantic tradition in art, its subsequent thematic legacy and its influence upon my own work

This study is comprised of a written exegesis and a folio of paintings and drawings. It explores the view that Romanicism in Britain survived its historical period and continues to influence contemporary British artists. Concentrates upon the prominence given by the Romantics to symbols, most commonly located in nature, which express spiritual impulses and ideas related to human destiny and feelings.

Origins of agriculture at Kuk Swamp in the highlands of New Guinea

Multidisciplinary investigations at Kuk Swamp in the Highlands of Papua New Guinea show that agriculture arose independently in New Guinea by at least 6950 to 6440 calibrated years before the present (cal yr B.P.). Plant exploitation and some cultivation occurred on the wetland margin at 10,220 to 9910 cal yr B.P. (phase 1), mounding cultivation began by 6950 to 6440 cal yr B.P. (phase 2), and ditched cultivation began by 4350 to 3980 cal yr B.P. (phase 3). Clearance of lower montane rainforests began in the early Holocene, with modification to grassland at 6950 to 6440 cal yr B.P. Taro (Colocasia esculenta) was utilized in the early Holocene, and bananas (Musa spp.) were intensively cultivated by at least 6950 to 6440 cal yr B.P.

Dummett and the origins of analytical philosophy

Michael Dummett has argued that the linguistic turn, initiated by Frege, is the decisive moment in the birth of the analytical tradition and what distinguishes that tradition from other movements. The thesis of the paper is that Dummett’s account of the origins of the analytical tradition understates the extent to which Frege’s work, and the linguistic turn more generally, are responses to antinomies in the modern philosophical project. An adequate characterisation of the origins of the analytic tradition presupposes an account of the fundamental conceptual shift that occurred during the time of the scientific revolution and the epistemological problems that arose in conjunction with this shift. This is why it is misleading to assert, with Dummett, that the really interesting developments in terms of understanding the analytical tradition are subsequent to Frege. The most productive contrast in terms of understanding the origins of the analytical tradition is not between pre and post Fregean thought, the paper argues, but between modern and premodern conceptions of philosophy and its relation to the world of everyday experience.

Orientalism and the Australian news media : origins and questions

The author draws on his expertise in Middle Eastern history and Western philosophical thought, presenting an ambitious chapter that traces the origins of orientalist discourse from the 18th and 19th century Europe to the beginnings of the Australian press. The chapter identifies the parallels between this discourse and the most contemporary representations of Islam and Muslims in the Australian news media. It documents that a key challenge for those working for the Australian news media is firstly to recognise the extent to which orientalist thought influences the reporting of Islam and Muslims and then to transcend the centuries-old view of this faith and its adherents as a threatening other.

Origins of adaptive immunity

Adaptive immunity, involving distinctive antibody- and cell-mediated responses to specific antigens based on "memory" of previous exposure, is a hallmark of higher vertebrates. It has been argued that adaptive immunity arose rapidly, as articulated in the "big bang theory" surrounding its origins, which stresses the importance of coincident whole-genome duplications. Through a close examination of the key molecules and molecular processes underpinning adaptive immunity, this review suggests a less-extreme model, in which adaptive immunity emerged as part of longer evolutionary journey. Clearly, whole-genome duplications provided additional raw genetic materials that were vital to the emergence of adaptive immunity, but a variety of other genetic events were also required to generate some of the key molecules, whereas others were preexisting and simply co-opted into adaptive immunity.

Ionic liquid mixtures—variations in physical properties and their origins in molecular structure

In order to explore the various possible property trends in ionic liquid mixtures, five different ionic liquids were mixed with N-methyl-N-propylpyrrolidinium bis(trifluoromethylsulfonyl)amide ([C₃mpyr][NTf₂]), and the viscosities, excess molar volumes, ionic conductivities, and phase diagrams of the mixtures were determined over a range of temperatures. In a number of the mixtures the crystallization of both components was completely suppressed and no melting point was observable. Such mixtures of similar ionic liquids thus have potential for use in low-temperature applications by extending the liquid range to T_g. The molar conductivities and viscosities are described as approximating predictable or “simple” mixing behaviors, while excess molar volumes were found to show a variety of mixing and nonideal mixing effects. Mixture equations for viscosity and conductivity are discussed and analyzed. An immiscibility window was observed in the trihexyl(tetradecyl)phosphonium bis(trifluoromethylsulfonyl)amide ([P_6,6,6,14][NTf₂]) in the [C₃mpyr][NTf₂] system in the [C₃mpyr][NTf₂]-rich region. Unusual physical properties are exhibited by miscible compositions near the demixing line. These compositions are described as [P_6,6,6,14][NTf₂]-like, even up to 0.5 mol fraction of [C₃mpyr][NTf₂].

Australia and appeasement : imperial foreign policy and the origins of World War II

This book examines Australia's role in the British Empire's policy of Appeasment in the years from the time Hitler came to power 1933 to the outbreak of the European War in September 1939. Focusing on the five leading figures in the Australian governments of the 1930s - Joe Lyons, Stanley, Bruce, Robert Menzies, Billy Hughes and Ricahrd Casey - this book examines their responses to the rise of Hitler and the gowing threat of fascism. It provide new insights into the history of Australian foreign policy, British imperial history and the history of the Origins of the Second World War. 

Developmental origins of obesity-related hypertension

1. In the past 30 years the prevalence of obesity and overweight have doubled. It is now estimated that globally over 500 million adults are obese and a further billion adults are overweight. Obesity is a cardiovascular risk factor and some studies suggest that up to 70% of cases of essential hypertension may be attributable, in part, to obesity. Increasingly, evidence supports a view that obesity-related hypertension may be driven by altered hypothalamic signalling, which results in inappropriately high appetite and sympathetic nerve activity to the kidney.

2. In addition to the adult risk factors for obesity and hypertension, the environment encountered in early life may ‘programme’ the development of obesity, hypertension and cardiovascular disease. In particular, maternal obesity or high dietary fat intake in pregnancy may induce changes in fetal growth trajectories and predispose individuals to develop obesity and related sequelae.

3. The mechanisms underlying the programming of obesity-related hypertension are becoming better understood. However, several issues require clarification, particularly with regard to the role of the placenta in transferring fatty acid to the fetal compartment, the impact of placental inflammation and cytokine production in obesity.

4. By understanding which factors are most associated with the development of obesity and hypertension in the offspring, we can focus therapeutic and behavioural interventions to most efficiently reduce the intergenerational propagation of the obesity cycle.
