Continuous Characterization of the Planform Geometry and Curvature of Meandering Rivers

The complex feedback between process and form that governs planform migration of meandering rivers is still incompletely understood. Current theoretical models aimed at predicting planform migration relate the rate of meander migration at a particular location to the channel curvature at and upstream of that location. However, these models are still incapable of reproducing complex forms of bend development, such as compound loops. Evaluation of such models requires a representation of planform curvature better than that provided by traditional methods where the curvature is calculated from directional change between the successive digitized points—an approach that provides a discrete representation of curvature dependent on the density of the digitized points used to characterize the channel planform. This article presents and evaluates a methodology that provides a continuous functional representation of the planform geometry and curvature of meandering rivers. The method involves the fitting of splines, specifically parametric cubic splines (PCSs), to discrete digitization data of the channel centerline (CL) and the arc-length parameterization of the resulting composite curve. The arc-length parameterized PCS-interpolated curve is then used to compute analytically the channel CL location and curvature for any value of the streamwise axis. Evaluation of the method involves examination of the effects of digitization interval size and digitization error on the characterization of the planform geometry and curvature using PCS fitting. The derivation of curvature values from continuous planform function for any location and any spatial interval overcomes the reliance either on average bend curvature values or on discrete curvature values based on digitized points.     

Analysing musical culture in nineteenth-century Europe: towards a musical turn?

The aim of this article is to establish the extent to which the history of music can offer new perspectives on the modern period. We need a change of perspective, moving away from the aesthetic debates on music to an investigation of actual experiences and practices of participants. Audience behaviour provides a link between musical production and society. In order to make opera houses and concert halls visible as social spheres, this article draws on examples from the musical life of Berlin and London in the 1800s. Music should no longer be regarded as a peripheral phenomenon, but instead as a potential historical question. The analysis of musical performances prompts at least one: music matters.     

Bank Erosion in the Bellinger Valley,New South Wales: Definition and Management

Lateral channel migration is normal or autogenic, with bank erosion often on concave and accretion on convex banks. Where bank erosion occurs, particularly at an accelerated rate through land abuse and an increase in flood magnitude and frequency or allogenic, it threatens human use of the flood plain. There is a demand for protection, often with very little understanding of the erosion hazard. Measurements based on photogrammetry were used to define bank erosion and accretion, as well as width changes, in eight meander arcs (11 sections in each) over 41 years. It was concluded that, if this rate continued over the next century, 82 ha of alluvial land, 6.2 km of roads, two bridges, 9 homes and 51 home sites could be lost. Various management options, costs and benefits are given in order to show how future planning and protection can be more rational.     

The Dimensions of Politics and Voter Behaviour in Preferential Systems: The Case of Australia

This project examines the dimensions of politics and voter preferences in Australia. Evidence from an empirical spatial analysis provides that Australian parties and voters are organised along a unidimensional socioeconomic continuum. Numerous individual-level factors, including party identification, ideology and a host of demographic and opinion variables, predict voters' positions along the continuum. Moreover, voter locations are shown to relate strongly to vote choice, demonstrating the importance of socioeconomic positions to voter behaviour in Australia. Finally, because this approach allows for a full examination of voter preference orderings, it is important to the study of voting behaviour and representation under preferential electoral institutions in Australia and elsewhere.     

Palaeoenvironmental reconstruction at an oxbow lake situated at the lower Nottawasaga River,southern Ontario,Canada

Abstract

The purpose of this investigation at the lower Nottawasaga River in southern Ontario, Canada, was to reconstruct the impact of base level on fluvial stability and human occupation during the Holocene in a topographically confined section, where the river cuts through the Edenvale Moraine. Three cores were extracted from an oxbow lake (Doran Lake) and a ground-penetrating radar survey was executed in its vicinity to study wider subsurface alluvial architecture. Radiocarbon dating suggests that the Nottawasaga River became entrenched in the Edenvale Moraine early in the Holocene, with base-level lowering in the Lake Huron basin, and that Doran Lake formed towards the middle Holocene as a meander cutoff when water levels in the Lake Huron basin increased, leading to a period of fluvial instability, enhanced flow and floodplain aggradation. Fluctuating lake levels would have affected human settlement as well as the preservation and visibility of archaeological remains predominantly through vertical accretion.     

Food and social complexity at Çayönü Tepesi,southeastern Anatolia: Stable isotope evidence of differentiation in diet according to burial practice and sex in the early Neolithic

The identification of early social complexity and differentiation in early village societies has been approached in the past most notably through the evaluation of rituals and architectural layouts. Such studies could be complemented by an approach that provides data about everyday behaviours of individuals. We took 540 human and animal bone samples for stable carbon and nitrogen isotope analysis from the Neolithic site of Çayönü Tepesi in southeastern Anatolia. The inhabitants at this site chose to bury their dead in two different ways at different times during its occupation: beneath the floors of their houses, but also inside a public mortuary building known as the Skull Building. This variation provides an opportunity using isotope methods to test whether there was evidence for structuring of daily activities (diet in this case) that might serve to reinforce this change in burial practice. We show that when the inhabitants of Çayönü Tepesi changed their architecture and operated different burial practices in conjunction, this coincided with other aspects of behaviour including socially-constituted food consumption practices, which served to reinforce social identities.     

Hegemony,liberalism and global order: what space for would‐be great powers?

This article, and the four that follow, consider some of the ways in which China, Russia, India and Brazil have responded both to US hegemony and to the changing character of international society. This article sets out some of the major analytical questions that emerge when thinking about the foreign policy options of these countries and some of the principal conceptual and theoretical categories within which those questions may be usefully framed. The first section examines the reasons for taking these countries as a group. The second section provides a brief overview of two of the most common theoretical perspectives from which the systemic pressures on these countries have been understood. The third considers their actual and potential strategies and options under five headings: their status as regional powers; their behaviour within and towards international institutions; their relations with the United States; collaboration among them and evidence for the possible emergence of balancing behaviour; and the links between economic development and foreign policy.     

Travel Blending: Whither Regulation?

Travel blending, as a form of travel demand management, has in recent times been celebrated by transport planners as a means of shaping travel behaviour without regulation. Accordingly, travel blending is said to overcome the problems of the state bureaucracy imposing its will upon the individual’s travel choices. In this paper we introduce a Foucauldian analysis to the field of transport in order to examine the assertions made by proponents of travel blending that they are not exercising power in the course of shaping travel behaviour. In particular, we use recent elaborations of Foucault’s work on governmentality to explore the ways in which the sites, subjects and objects of travel are discursively constituted within travel blending thereby enabling new ways of intervening upon the travelling subject. We suggest that a governmentality approach not only provides a fertile means of investigating transport but also reveals travel blending as a regulatory practice serving to structure the individual’s field of action.     

MODELLING OF NONLINEAR DYNAMIC BEHAVIOUR OF A SHALLOW STRIP FOUNDATION WITH MACRO-ELEMENT

A new nonlinear soil-structure interaction macroelement is presented. It models the dynamic behaviour of a shallow strip foundation under seismic action. Based on sub-structured methods, it takes into account the dynamic elastic effect of the infinite far field, and the material and geometrical nonlinear behaviour produced in the near field of the foundation. Effects of soil yielding below the foundation as well as uplift at the interface are considered. Through the concept of macro-element, the overall elastic and plastic behaviour in the soil and at the interface is reduced to its action on the foundation. The macro-element consists of a non linear joint element, expressed in the three degrees of freedom of the strip foundation, reflecting the limited bearing capacity of the foundation. This model provides a practical and efficient tool to study the seismic response of a structure in interaction with the surrounding soil medium. Applications to a bridge pier show the potentialities of this kind of model.     

Middle power,status-seeking and role conceptions: the cases of Indonesia and South Korea

This article examines how role theory can enhance the middle-power literature in understanding the role preferences of middle powers. Rather than treating it as merely a function of material capability or good international citizenship, this article resituates middle power as a concept of international status that states aim to pursue through the enactment of role conceptions. Thus, it reinstates a conceptual distinction between ‘middle-power status’ and ‘middle-power roles’. The article suggests that the notion of role conceptions can analytically connect the status-seeking behaviour of middle powers with their foreign policy agenda. In so doing, it provides a more nuanced explanation of middle-power behaviour, which might differ between one middle power and another. Using Indonesia and South Korea as case studies of middle power, this article contends that foreign policymakers have strategically conceptualised and enacted several main roles that aim to capture historical experience, as well as ego and alter expectations, in order to pursue middle-power status. These role conceptions determine the foreign policy agenda of states in articulating their middle-power status.     

Trends and Implications of Delayed and Non-Marriage in Korea

Korea has experienced marital transition since the 1920s, but recent data reveal rapid changes in marital behaviour and norms. Analysts usually relate these to the second fertility transition, fast growing gender equality, economic developments, and ideational changes, pointing to the necessity of understanding the process of change in marital behaviour in the context of societal transformation as well as demographic transition. With this background in mind, this paper constructs refined measures, such as age-specific first marriage rates and total first marriage rates, for different time periods and for different cohorts to present a clearer picture of marriage trends. The results are then examined in relation to various social and demographic factors, a procedure which provides an indirect check on the validity and usefulness of the method.     

RESISTANCE AND STRATEGIC RESPONSES IN FOOD SUPPLY NETWORKS: METRO CASH & CARRY IN BANGALORE

The transnational expansion of large retail and wholesale companies such as Metro, Carrefour and Wal‐Mart has caused changes in the market situation and consequent power shifts, not only in the retail sector but also in the supply networks in host countries. These developments at least potentially endanger the livelihoods of old established retailers, intermediaries and employees of these businesses. Thus, it is not surprising that the investments of the transnational companies can result in resistance from those affected. As an analysis of Metro and its activities in the federal state of Karnataka in India shows, this resistance can influence the activities of the company to develop a modern supply network. This study analyses the way in which the actors of resistance develop and exercise power and how this in turn influences Metro. The global production network (GPN) approach is used as an analytical framework. The results emphasize the importance of networks external to the firm for the analysis of processes of globalization. The company's behaviour cannot be understood unless the resistance is taken into account. The study shows that the GPN framework provides the tools to analyse the influence of actors such as civil society groups, trade unions and associations as part of the production network. However, up to now this option has rarely been used.     

Behaviour as a thing

This article reflects on issues arising from attempts to treat behaviour as an object of scientific and social scientific study. It examines what happens when behaviour is taken as a thing, an object of concern, modification and enquiry. At the heart of the notion of behaviour, this article argues, lies a fundamental ambiguity. The concept’s power, but also its elusiveness, lies in its ability to tack back and forth between two visions: on the one hand behaviour as materialized, objectified action, regular, repetitive and rule-bound, and on the other behaviour as a placeholder, a word to index something we do not yet know or understand. Those are two ways of being a ‘thing’.     

The bad things we do because of empathy

ABSTRACT

Empathy is usually seen as a prosocial and morally positive influence on behaviour. This article provides an overview of cases of negative acts motivated by empathy. It includes discussions of polarizations that are fueled by side-taking and empathy, selfish forms of empathy (such as sadistic empathy, vampirism, and helicopter parenting), and filtered empathy (using identification with a third person as a medium to have empathy with another). The definition of empathy used is to co-experience the situation of another.     

The role of shellfish in hunter–gatherer societies during the Early Upper Palaeolithic: A view from El Cuco rockshelter,northern Spain

The role of coastal resources in the subsistence strategies of Palaeolithic human populations has only recently become an important topic in Old World archaeology. Information on the exploitation of these resources, both as foodstuffs and symbolic elements, can be used to infer the emergence of modern human behaviour as well as to track the diversification and intensification of human diet over time. The excavations carried out at El Cuco rockshelter, located in northern Spain have provided evidence for the exploitation of marine resources during the Early Upper Palaeolithic. The accumulation of Patella shells at El Cuco provides the largest accumulation and the first clear evidence of collection and consumption of molluscs during the Aurignacian on the Atlantic Façade of Europe. A deposit of ornamental shells appeared in a very homogeneous context dated to the Gravettian, suggesting that the shells belonged to the same item. The analysis of this evidence has allowed us to conclude that marine resources were systematically used at least from the beginning of the Upper Palaeolithic in the region. However, a comparison with the Mesolithic shows that intensive shellfish gathering did not occur until the end of the Upper Palaeolithic. Regarding the ornaments, it is interpreted that the identified shell beads were used as social or personal status markers.     

Towards Household Sustainability in Sydney? Impacts of Two Sustainable Lifestyle Workshop Programs on Water Consumption in Existing Homes

Residential water consumption accounts for approximately 70 per cent of Sydney's water consumption. The capacity of households to reduce water consumption is limited by expectations and conventions of water supply shaped by existing water infrastructure ( Allon and Sofoulis, 2006 ) and ‘saver‐unfriendly’ household water fittings ( Sofoulis, 2005 ). Sustainable lifestyle workshop programs – many of which address water use – are relatively new, and rigorous research into their impacts is scarce. Existing research generally relies on reported behaviour change from participants, which is then used to estimate resource savings. This paper examines water consumption data, and the questionnaire responses of participants in two sustainable lifestyle workshop programs, to examine whether reported behavioural and technical changes are translating into significant water savings. The Sustainability Street (Penrith) and GreenHome (Parramatta) programs are changing participant behaviours, but reductions achieved by Sustainability Street are not significant at the 0.05 level. GreenHome reductions, while significant, cannot be fully attributed to the program due to the downward trend commencing prior to the program. The improved behaviour of participants – in comparison to their previous behaviour and the behaviour of non‐participants – is thus not translating into significant water savings. This indicates that the relationship between improved environmental behaviour and actual water savings is not as straightforward as program operators might assume. The implications of this are that research should use real consumption data and not estimations derived from behaviour change, and strategies to reduce household water consumption need to involve bigger technical changes to household water infrastructures.     

The Moral Politics of Gendered Labour in Artisanal Mining in Sierra Leone

Drawing on current anthropological approaches to labour, this article examines some of the moral politics mobilized around women and artisanal mining in policy-inflected scholarship with reference to particular gold mining zones in Tonkolili district, Sierra Leone. In so doing, the article proposes that such a focus on labour not only allows one to appreciate how sentiments concerning (im)proper behaviour infuse wider policy proposals to amend social arrangements in regard to what is called ‘artisanal mining’, but it also offers insight into some of the enduring moral politics helping to constitute women as ‘family workers’ in the actual artisanal gold mining zones. The article suggests that examining the overlapping moral politics constituting women's labour practices provides a more supple understanding of the contested economic possibilities for women in this livelihood practice.     

Ruodlieb VIII, 103

The essential question in this article is why Cyprian chose to suffer martyrdom sub Valeriano and not sub Decio eight years earlier. In his letters Cyprian defended what he called his withdrawal from the persecutors by referring to his obedience to God but also to his responsibilities as a bishop. It is claimed that Cyprian both in 250 and 258 acted as a patronus for his congregation, his behaviour being typical of an aristocratic pattern of behaviour.     

What are patterns in the humanities?

ABSTRACT

This paper is concerned with patterns in past human behaviour, what they are, and how this relates to the detection of patterns in data by means of computation. Theorists have not given patterns the attention they deserve. Therefore it is far from clear what patterns are and to what purpose scholars may use them. This paper presents eight propositions on patterns which hold true for patterns found ‘by hand’ and patterns found ‘by computation’. One such is that a pattern is discernible in behaviour when we subject it to the intentional stance, as the philosopher Daniel Dennett argues. Here behaviour is part of an intentional system. This paper’s argument is that the patterns found ‘by computation’ too are part of an intentional system. To substantiate this claim this paper discusses two important examples of detecting computational patterns in the domain of the humanities.
