Confidence in beliefs about pain predicts expectancy effects on pain perception and anticipatory processing in right anterior insula.

Psychological factors play a major role in exacerbating chronic pain. Effective self-management of pain is often hindered by inaccurate beliefs about the nature of pain which lead to a high degree of emotional reactivity. Probabilistic models of perception state that greater confidence (certainty) in beliefs increases their influence on perception and behavior. In this study, we treat confidence as a metacognitive process dissociable from the content of belief. We hypothesized that confidence is associated with anticipatory activation of areas of the pain matrix involved with top-down modulation of pain. Healthy volunteers rated their beliefs about the emotional distress that experimental pain would cause, and separately rated their level of confidence in this belief. Confidence predicted the influence of anticipation cues on experienced pain. We measured brain activity during anticipation of pain using high-density EEG and used electromagnetic tomography to determine neural substrates of this effect. Confidence correlated with activity in right anterior insula, posterior midcingulate and inferior parietal cortices during the anticipation of pain. Activity in the right anterior insula predicted a greater influence of anticipation cues on pain perception, whereas activity in right inferior parietal cortex predicted a decreased influence of anticipatory cues. The results support probabilistic models of pain perception and suggest that confidence in beliefs is an important determinant of expectancy effects on pain perception.

大型反倾岩体变形破坏机制及稳定性分析———以金沙江宽谷坝址龙蟠边坡为例

A large number of catastrophic accidents were aroused by the instability and destruction of anti-dip rock masses in the worldwide engineering projects, such as hydropower station, mine, railways and so on. Problems in relation to deformation and failure about anti-dip rock slopes are significant for engineering geology research. This dissertation takes the Longpan slope in the Jinsha River as a case to study the deformation mechanism of large-scale anti-dip rock masses and the slope stability analysis method. The primary conclusions are as follows. The Dale Reach of Jinsha River, from Longpan to the debouchment of Chongjiang tributary, is located in the southeastern margin of the Qinghai-Tibet Plateau. Longpan slope is the right embankment of Dale dam, it is only 26 km to the Shigu and 18 km to Tiger Leaping Gorge. The areal geology tectonic structures here area are complicated and blurry. Base on the information of geophysical exploration (CSAMT and seismology) and engineering geological investigation, the perdue tectonic pattern of Dale Reach is put forward for the first time in this paper. Due to the reverse slip of Longpan fault and normal left-rotation of Baihanchang fault, the old faulted valley came into being. The thick riverbed sediments have layered characters of different components and corresponding causes, which attribute to the sedimentary environments according with the new tectonic movements such as periodic mountain uplifting in middle Pleistocene. Longpan slope consists of anti-dip alternate sandstone and slate stratums, and the deformable volume is 6.5×107m3 approximately. It was taken for an ancient landslide or toppling failure in the past so that Dale dam became a vexed question. Through the latest field surveying, displacement monitoring and rock masses deforming characters analyses, the geological mechanism is actually a deep-seated gravitational bending deformation. And then the discrete element method is used to simulate the deforming evolution process, the conclusion accords very well with the geo-mechanical patterns analyses. In addition strength reduction method based on DEM is introduced to evaluate the factor of safety of anti-dip rock slope, and in accordance with the expansion way of the shear yielding zones, the progressive shear failure mechanism of large-scale anti-dip rock masses is proposed for the first time. As an embankment or a close reservoir bank to the lower dam, the stability of Longpan slope especially whether or not resulting in sliding with high velocity and activating water waves is a key question for engineering design. In fact it is difficult to decide the unified slip surface of anti-dip rock slope for traditional methods. The author takes the shear yielding zones acquired form the discrete element strength reduction calculation as the potential sliding surface and then evaluates the change of excess pore pressure and factor of stability of the slope generated by rapid drawdown of ponded water. At the same time the dynamic response of the slope under seismic loading is simulated through DEM numerical modeling, the following results are obtained. Firstly the effective effect of seismic inertia force is resulting in accumulation of shear stresses. Secondly the discontinuous structures are crucial to wave transmission. Thirdly the ultimate dynamic response of slope system takes place at the initial period of seismic loading. Lastly but essentially the effect of earthquake load to bringing on deformation and failure of rock slope is the coupling effect of shear stresses and excess pore water pressure accumulation. In view of limitations in searching the critical slip surface of rock slope of the existing domestic and international software for limit equilibrium slope stability analyses, this article proposes a new method named GA-Sarma Algorithm for rock slope stability analyses. Just as its name implies, GA-Sarma Algorithm bases on Genetic Algorithm and Sarma method. GA-Sarma Algorithm assumes the morphology of slip surface to be a broken line with traceability to extend along the discontinuous surface structures, and the slice boundaries is consistent with rock mass discontinuities such as rock layers, faults, cracks, and so on. GA-Sarma Algorithm is revolutionary method that is suitable for global optimization of the critical slip surface for rock slopes. The topics and contents including in this dissertation are closely related to the difficulties in practice, the main conclusions have been authorized by the engineering design institute. The research work is very meaningful and useful for the engineering construction of Longpan hydropower station.

‘Is there a right time for gender just peace? Feminist anti-war organising revisited’

This paper addresses the question of totalising gender power relations that have led to and shaped the wars of the 1990s in Yugoslavia and the emerging ethno-national states on the ‘periphery’ of Europe. I argue that the same type of gender power relations continue to dominate the region, notably Serbia, and to perpetuate gender inequalities and gender based violence in its many everyday and structural forms, causing profound levels of human insecurity. My analysis aims to set in motion a debate on how to tackle these continuing gender inequalities and GBV in post-war societies. In so doing, I propose a shift from focusing on the hierarchy of victimisation that has characterised much of the feminist analyses, activism and scholarly work in relation to these (and other) conflicts, to a relational understanding of the gendered processes of victimisation in war and peace, that is - of both women and men. Such an approach holds a potential to undermine the power systems that engender these varied types of victimisation by ultimately reshaping the notions of masculinity and femininity, which are central to the gender power systems that generate gender unjust peace.

How large is congressional dependence in agriculture. Bayesian inference about ‘scale’ and ‘scope’ in measuring a spatial externality

The political economy literature on agriculture emphasizes influence over political outcomes via lobbying conduits in general, political action committee contributions in particular and the pervasive view that political preferences with respect to agricultural issues are inherently geographic. In this context, ‘interdependence’ in Congressional vote behaviour manifests itself in two dimensions. One dimension is the intensity by which neighboring vote propensities influence one another and the second is the geographic extent of voter influence. We estimate these facets of dependence using data on a Congressional vote on the 2001 Farm Bill using routine Markov chain Monte Carlo procedures and Bayesian model averaging, in particular. In so doing, we develop a novel procedure to examine both the reliability and the consequences of different model representations for measuring both the ‘scale’ and the ‘scope’ of spatial (geographic) co-relations in voting behaviour.

Development of a ESES Solar Thermal Lab on Full Scale System

The main aim of this project is to develop an ESES lab on a full scale system. The solar combisystem used is available most of the time and is only used twice a year to carry out some technical courses. At the moment, there are no other laboratories about combisystems. The experiments were designed in a way to use the system to the most in order to help the students apply the theoretical knowledge in the solar thermal course as well as make them more familiar with solar systems components. The method adopted to reach this aim is to carry out several test sequences on the system, in order to help formulating at the end some educating experiments. A few tests were carried out at the beginning of the project just for the sake of understanding the system and figuring out if any additional measuring equipment is required. The level of these tests sequences was varying from a simple energy draw off or collector loop controller respond tests to more complicated tests, such as the use of the ‘collector’ heater to simulate the solar collector effect on the system. The tests results were compared and verified with the theoretical data wherever relevant. The results of the experiment about the use of the ‘collector’ heater instead of the collector were positively acceptable. Finally, the Lab guide was developed based on the results of these experiments and also the experience gotten while conducting them. The lab work covers the theories related to solar systems in general and combisystems in particular. 

"I will start treatment when I think the time is right":HIV-positive gay men talk about their decision not to access antiretroviral therapy.

In a qualitative study, 20 HIV-infected Australian gay men were interviewed about their decision not to access antiretroviral drug therapy. The main reasons given for the decision were fear of side effects; fear of long-term damage to body organs; the inconvenience of the treatment regimens; belief that the regimen's demands would be a threat to morale; and belief that there was no reason to start therapy in the absence of AIDS-related symptoms. Actions taken by the men to monitor and maintain their health included seeing a doctor regularly; having regular T-cell and viral load tests; and trying to maintain a positive outlook by not letting HIV/AIDS 'take over' their lives. Almost half the men considered they had been subjected to unreasonable pressure to access therapy and there was considerable pride at having resisted this pressure. The findings suggest that the men disagreed with the biomedical model for managing HIV/AIDS only on the question of if and when to access therapy. They also suggest that underlying the men's dissent from the biomedical model was a different mode of thinking than is required by the model: while the model demands thinking that is abstract, the men focused strongly on factors close to the 'here and now' of immediate experience. The practical implications of the findings are explored.

Social justice in education in 'new times'

This thesis considers social justice in education in ‘new times’. To facilitate the investigation a number of research questions were pursued. These questions were: • What is meant by the label ‘social justice’? • How is social justice to be understood in contemporary terms? • Are there tensions between traditional and contemporary views of social justice? • How effective are policy developments in delivering social justice via education? • What difference do such policies make at the local level? To answer these questions a critical case analysis of a country community and one of its primary schools was carried out. Data were gathered using a variety of methods. As a researcher who was also a teacher in the school I kept a personal professional journal during 1993 and 1994. During this period I was the teacher in the school with responsibility for curriculum development related to issues of social justice. In 1994 I conducted interviews with twenty students, parents and teachers at the school in relation to social justice issues. I also interviewed the CEO of the town’s Council. A number of relevant Federal and State Government and school policy documents were consulted and an archival search of the local newspaper from 1956 to 1994 was undertaken. Statistical information from the Australian Bureau of Statistics as well as from school records was used. A number of local history books were consulted as well as the minutes of relevant school committee meetings. Contemporary social theory, more specifically the work of Anthony Giddens, provided the major methodological tool. Giddens structuration theory was selected as it provided a way of interpreting society from both macro and micro perspectives, it provided a way of studying the interconnectedness of the individual and society. In addition to this, a metaphor was used as a way of developing an understanding of the data. The river was chosen as the metaphor as it has significance to the case study community and it also provides a way of understanding interconnectedness. At an interpretive level, both social theory and moral philosophy were drawn on, including the work of Geoffrey Sharp, Anthony Giddens and Alisdair MacIntyre. A review of selected literature indicated three main areas of concern in relation to this thesis. We live in a time of constant and ongoing change, understanding how this change impacts on the lives of individuals and society is important. Such an understanding relates directly to issues of ontology. In addition it was necessary to consider schools in these ‘new times’. The literature revealed that the changes occurring in the wider society were related to the changes currently being seen in schools. Specifically this related to the increasing emphasis on economics and on individualism, emphases also reflected in the findings of this thesis. Finally the literature related to social justice was discussed, the focus here was on distributive theories of justice and the way these are reflected in programs such as the DSP. The data, as expressed in the metaphor of the flowing river, revealed dominant and marginal currents in social justice in education in ‘new times’. The dominant social group are the intellectually trained and the dominant issues were related to technology, globalisation and economic and bureaucratic rationalism. In the marginal currents we find the under-employed and the unemployed and marginal issues relating to housing, the black economy, poverty and the survival of rural communities. The data also revealed a marginal tributary running into the river. This tributary shows that social cohesion is still a part of life in ‘new times’, albeit a marginalised part. The dominant and marginal currents in social justice in ‘new times’ reveal changes at a deep cultural level. Social justice in ‘new times’ is set within the limits provided by economic rationalism. Such a position is closely linked to the rise of liberal democracy as a political ideology. A rise which has been on a global scale. This valorizes the individual as compared with the group, and the family as compared to the social whole, within the context of expanded economic groupings and markets. Such an ideological position sees the role of the state as providing the ‘legitimising muscle’ to advance the cause of individuals and their families as compared to larger social groupings. These perceptions were applied in Australia, even under a Labor Government. In this sense social justice policies in ‘new times’ are ideological, they act as a political lever to legitimate economic restructuring. They are policies designed to carry disparate groups forward and together on a common wave of economic reform. They are used to ‘sell’ economic reform as being ‘good’ for all of society. Against the backdrop of economic rationalism and liberal democratic ideals there emerges a language geared to the production of an economically viable self, self image, self identity, self esteem and self confidence. As a result, the sense of identity as ‘social’ is lost from view. This thesis argues that what is needed is a new way of looking at social justice in education. A way that reaches beyond the solutions forwarded by the political Left and the Right. It is about the development of an understanding of the way in which an assimilation of the hyper individual and the social group can result in the emergence of the socially responsible individual. This is a cultural shift that sees the individual/society dualism presented in a new way. The categories enter into a new relationship where the balance shifts away from the individual towards society. A shift to a culture where the individual’s rights and responsibilities are respected within a social whole. Such a cultural shift would result in a curriculum which would build social identity, promoted socially responsible independent thought and make space for creativity and the aesthetic. A ‘curriculum for social responsibility’ would be a socially just curriculum.

An agent-based approach to value theory and wealth distribution in economics

Any attempt to model an economy requires foundational assumptions about the relations between prices, values and the distribution of wealth. These assumptions exert a profound influence over the results of any model. Unfortunately, there are few areas in economics as vexed as the theory of value. I argue in this paper that the fundamental problem with past theories of value is that it is simply not possible to model the determination of value, the formation of prices and the distribution of income in a real economy with analytic mathematical models. All such attempts leave out crucial processes or make unrealistic assumptions which significantly affect the results. There have been two primary approaches to the theory of value. The first, associated with classical economists such as Ricardo and Marx were substance theories of value, which view value as a substance inherent in an object and which is conserved in exchange. For Marxists, the value of a commodity derives solely from the value of the labour power used to produce it - and therefore any profit is due to the exploitation of the workers. The labour theory of value has been discredited because of its assumption that labour was the only ‘factor’ that contributed to the creation of value, and because of its fundamentally circular argument. Neoclassical theorists argued that price was identical with value and was determined purely by the interaction of supply and demand. Value then, was completely subjective. Returns to labour (wages) and capital (profits) were determined solely by their marginal contribution to production, so that each factor received its just reward by definition. Problems with the neoclassical approach include assumptions concerning representative agents, perfect competition, perfect and costless information and contract enforcement, complete markets for credit and risk, aggregate production functions and infinite, smooth substitution between factors, distribution according to marginal products, firms always on the production possibility frontier and firms’ pricing decisions, ignoring money and credit, and perfectly rational agents with infinite computational capacity. Two critical areas include firstly, the underappreciated Sonnenschein-Mantel- Debreu results which showed that the foundational assumptions of the Walrasian general-equilibrium model imply arbitrary excess demand functions and therefore arbitrary equilibrium price sets. Secondly, in real economies, there is no equilibrium, only continuous change. Equilibrium is never reached because of constant changes in preferences and tastes; technological and organisational innovations; discoveries of new resources and new markets; inaccurate and evolving expectations of businesses, consumers, governments and speculators; changing demand for credit; the entry and exit of firms; the birth, learning, and death of citizens; changes in laws and government policies; imperfect information; generalized increasing returns to scale; random acts of impulse; weather and climate events; changes in disease patterns, and so on. The problem is not the use of mathematical modelling, but the kind of mathematical modelling used. Agent-based models (ABMs), objectoriented programming and greatly increased computer power however, are opening up a new frontier. Here a dynamic bargaining ABM is outlined as a basis for an alternative theory of value. A large but finite number of heterogeneous commodities and agents with differing degrees of market power are set in a spatial network. Returns to buyers and sellers are decided at each step in the value chain, and in each factor market, through the process of bargaining. Market power and its potential abuse against the poor and vulnerable are fundamental to how the bargaining dynamics play out. Ethics therefore lie at the very heart of economic analysis, the determination of prices and the distribution of wealth. The neoclassicals are right then that price is the enumeration of value at a particular time and place, but wrong to downplay the critical roles of bargaining, power and ethics in determining those same prices.

'Global’ is not just ‘out there’ but also ‘right here’: expectations and experiences in internationalised and globalised higher education

This paper reports on a study that took a cross-disciplinary and cross-institutional approach to investigate postgraduate student expectations and experiences in internationalised and globalised higher education. The researchers drew on Giddens’ theory of structuration1. They explored the way samples of specialist medicine trainees in the UK and pre-service teacher education students in Australia identify and make meaning of their circumstances in an era that is increasingly characterised by greater internationalisation of the student body and more globalised curricula. In this paper, we discuss some of the tensions students reported encountering, and propose several ways in which such tensions might be counteracted.
