Entropy maximization and input–output analysis

ABSTRACT

Wilson’s original introduction of the concept of entropy to the modelling of input–output and commodity flow systems provided a more flexible alternative to the prevailing state of the art. Following a brief review of prior approaches, the modified Wilson approach is presented and illustrated with an application to Korea. Thereafter, recent developments in entropy econometrics are explored to return to some of the initial concerns, namely the estimation and updating of input–output systems.     

Innovation,knowledge and relations – on the role of clusters for firms’ innovativeness

ABSTRACT

For more than two decades, theories on regional clusters have inspired economic and structural policies at the European, national and regional levels. Based on the assumption that clusters generate innovation, policy-makers at all levels of governance have adopted instruments and mechanisms to stimulate, resource and sustain clusters. Despite the considerable attention paid to the clustering phenomenon, empirical evidence on to what extent firms’ innovation activities benefit from operating in clusters is scarce and inconclusive. This paper contributes to the micro-foundation of clustering effects by examining the characteristics and activities of cluster firms in relation to their innovativeness. Bridging innovation, management and cluster theories, it is argued that structural and relational embeddedness, relational capital and absorptive capacity influence clustered firms' innovativeness. Partial least-squares structural equation modelling of data from 104 firms in two software and information technology service sector clusters reveals that firms’ structural embeddedness (i.e. frequency of interactions) in clusters and external networks facilitates innovation cooperation. Firms’ absorptive capacity reinforces this positive effect of cluster-internal interactions on innovation cooperation. Results also suggest a substitution effect of trust as relational control mechanisms for formal control mechanisms within the cluster. However, the study finds no significant impact of firms’ innovation cooperation within the cluster (i.e. relational embeddedness) on their innovation success.     

Modelling Resource Values and Climate Change Impacts to Set Preservation and Research Priorities

ABSTRACT

Climate change impacts will increase in their frequency and severity in the coming decades, resulting in compromised integrity or destruction of thousands of heritage resources. Efforts are needed to identify, record, and study resources that will be affected. To set research and preservation priorities, the vulnerability of resources to climate change impacts and their importance to scientific research, preservation, and other resource values needs to be understood. We advocate a modelling approach which predicts the location, timing, and severity of climate change impacts; identifies resources at risk, their resource values, and opportunity costs; and prioritises research and preservation options based on these assessments. The need for this approach is illustrated with examples from two coastal areas subject to different impacts and hosting different types of heritage resources: the Atlantic coast of Georgia in the United States and the Wismar Bight along the Baltic Sea in northern Germany.     

When transport becomes a destination: deaf spaces and networks on the Mumbai suburban trains

ABSTRACT

This article considers dense social interactions in commuter trains and their crucial role within city-wide networks. Literature on social interactions in public transport has focused on how commuters have short interactions with each other, or constitute groups of train friends, but without situating them in wider geographies. The article focuses on deaf people in the Mumbai metropolis who travel in compartments reserved for disabled people, chatting and exchanging news and information. These spatial practices are facilitated by the peninsular geography and train infrastructure of Mumbai. In order to produce deaf spaces, where deaf sociality and sign language use are the organizing principles, deaf people strategically board particular trains and particular compartments, and sometimes remain in the train beyond their original destination. Mobile phones are used to coordinate these meetings. The diversity of people meeting in the train is high, such as with regard to gender, age, religion, caste, class and divisions are either perpetuated or abated. Because these compartments provide a diverse range of deaf people a space for daily meetings on the way to and from their (mostly hearing) work places and families; they are very important spaces to maintain and expand networks in the wider Mumbai deaf community.     

Mathematical Modelling in Chemistry and Biology

Abstract

The interdisciplinary use of mathematics to study chemical reactions and biological phenomena can bring many advantages, such as the planning of experiments, the interpretation of observations, the development of theories and technological applications. A number of examples illustrate these points here, such as differential equations applied to reaction systems, the chemostat for biological growth, reaction diffusion processes, the challenge of modelling combustion mathematically and pattern formation of gradients in space. Powerful computers and elaborate graphic systems will in future assure for this mathematical treatment a wide and successful application.     

Spatial interaction and security: a review and case study of the Syrian refugee crisis

ABSTRACT

Sir Alan Wilson's ideas have been highly influential in the modelling of phenomena including migration, transport and economics. Latterly, research has explored the application of similar ideas to new problems at larger scales. Many of these studies relate to global challenges with significant policy implications. Here, we present an example in the form of original empirical work concerning forced migration associated with the current Syrian refugee crisis. We employ a spatial interaction framework to examine the flows of migrants fleeing Syria and the characteristics which influence their choice of destination country. In line with the broader literature, we find that shorter distances, economic prosperity, and cultural similarity (e.g. shared language) attract forced migrants, as does the probability of being granted asylum; a finding with potential implications for policy. Contrary to expectation, we find little influence for levels of security in potential host nations (e.g. absence of terrorism).     

Linking Research and Teaching: A staff‐student interview project

This paper describes a project used in the first-year curriculum that requires students to interview a member of staff about their research as a possible model to link research and teaching in the university. Through a critical evaluation, which draws upon responses canvassed from students and staff, the value of the project is assessed and its scope for application within other institutions suggested.     

Locke and the Elements of Natural Philosophy: Some Problems of Attribution

ABSTRACT

This paper argues that John Locke’s interactions with the Quakers and his reflections on their doctrines and behaviour provide the salient background for understanding the content and polemical orientation of the chapter on enthusiasm in An Essay concerning Human Understanding. The terms of reference and key features of the vocabulary of the chapter “Of Enthusiasm” that Locke added to the fourth edition of the Essay derive from the Quakers and from Locke’s critical reflections on their doctrine of immediate inspiration. While Locke acknowledged that the phenomenon was to be found among other religious groups, it was the Quakers whom Locke had in mind when he formulated his philosophical critique of enthusiasm.     

The Study of Time: Proceedings of the First and Second Conferences of the International Society for the Study of Time

Abstract

In the past, the nobility of science was taken for granted, and it was universally venerated. Today many scienti!, ts are depressed by the morally doubtful applications of science: the high ideals of science should prevent the application of science to weapons research. In comparing science and religion, the moral dimensions of science are stress, ed and their extension is urged. In this way the world can be saved from war and the dignity and nobility of science can be restored.     

Assessing the influence of agrochemicals on the rate of copper corrosion in the vadose zone of arable land Part 1: field experiments

Abstract

Part of a project that has attempted to answer the question ‘does the application of agrochemicals accelerate the corrosion of metals in the top 50cm of the soil? ’ is reported. We have approached the question by a combination of field-based experiments (on two sites), establishing laboratory microcosms (one involving simple aqueous systems and the other a series of simulated burial experiments) and by using geochemical modelling techniques to understand the processes involved. Two different experimental approaches in the field are documented — one using in situ monitoring of corrosion potentials and the other assessing the degree of induced corrosion using image analysis on recovered samples. The first was carried out on arable land close to the University of Bradford to which we applied different fertilizer regimes. The second was established on land owned by the University of Newcastle at Palace Leas, Morpeth, Northumberland, which has a documented field management regime extending back over one hundred years. We focus here on a sub-set of the data relating to the behaviour of the thinnest samples of copper in each case. There does seem to be some evidence of an effect resulting from the applied fertilizer, but the data are sometimes contradictory. We suggest a number of improvements for future field experiments that monitor in situ corrosion in the vadose zone.     

Towards a benign reburial context: the chemistry of the burial environment

Abstract

The successful reburial of exposed archaeological remains depends on the ability to recreate a benign preserving environment, especially for the desiccated and waterlogged environments that preserve organic and other valuable archaeological material. An introduction to the chemistry of soil and the burial environment is provided, covering the key variables: water, oxygen, cations and anions, pH, organic matter, clay and redox potential. The problems of monitoring these variables and their variation are highlighted. Recent work in monitoring the long-term effects of burial and the steps taken towards modelling actual burial environment chemistry are outlined. Factors to be considered when adding material for reburial are proposed. These include: the avoidance of soluble or potentially soluble minerals; the beneficial buffering effect of clays and organic matter; the minimization of changes in water level, redox potential and pH; and the desirability of retaining the porosity of the burial medium. This can often be achieved by re-using the soil in which the objects/structures were originally buried.     

The Applicability of Human Rights: A Voegelinian Interpretation

ABSTRACT

The human rights discourse is prevalent in our contemporary social and political setting. In large part it determines the way we understand justice and therefore plays a crucial role in shaping the way we think and act. But despite its prevalence and widespread acceptance, this discourse is not without its difficulties. One of the more persistent, significant, and well-documented problems associated with human rights is whether they are universal or relative in their application. The following essay attempts to confront this question from a novel and more informative perspective than the ones offered thus far. Analyzing the debate concerning the universality or relativity of human rights from within the intellectual framework of Eric Voegelin's philosophy of history, this essay endeavors to uncover the essence of human rights and thus bring to light their true function lest we burden them with tasks that are beyond their scope.     

In Praise of Interdisciplinary Archaeology

Abstract

The study of instabilities has long been a central aspect of physical theories and experimental investigation. Chaotic behaviour is a more recently recognized general feature of physical systems, expecially hard-driven dynamical systems. This review describes physical models illustrating these phenomena and seeks to indicate their application to understanding a variety of problems outside physics. Thus, the occurrence of instabilities is advanced as the reason why different sciences have developed independently, and why their results cannot be regarded as deducible from the fundamental laws of physics. In particular, sociology and political science are seen as attempting to deal with extreme cases of chaotic behaviour resulting from widespread instability. Finally, a simple physical model of stop-go oscillations is described, and interpreted as a warning against over-optimistic expectations that modern attempts at participatory democracy are compatible with a stable society.     

Municipal Contact Centres: A Slower Approach Towards Sustainable Local Development by E-government

Abstract

It is Swedish government policy to use information and communication technologies to increase sustainability. This has implications for planning and local organization of communities. In the municipalities where most public services are provided, there are growing numbers of local contact centres (CCs) aiming to meet citizens' needs for information and coordination of public services. The CCs localize public services and combine different services into a one-stop practice focusing on needs and demands of individual citizens and their unique situations. The municipalities hereby have to plan for service provision in new ways to meet more individualized needs that are also in line with improved sustainability. CCs are both local offices and advanced services on-line, as e-governmental services. E-government could be considered fast government, but this article aims to turn that obvious first impression upside down and discuss how e-government can slow down and make services more local, personalized and sustainable. Theoretically we take off from a time-geographical modelling of slow processes that has implication for slower, more sustainable development. Based on in-depth case studies of municipal CCs we argue that they are tools towards improved sustainability and localism, and that they are “slowing up” administrative processes. In particular, we point out that e-government has a potential to plan for, and promote, sustainability and slow local development.     

CONCEPTUAL DESIGN OF ISOLATION SYSTEMS FOR BRIDGE STRUCTURES

Abstract

In the first part of this paper the objectives of an isolation system for a bridge structure are discussed, in relation to modelling options and modification of the traditional capacity design principles. A displacement-based design approach is then presented, using a linear equivalent single degree-of-freedom model. The preliminary design of an isolation system for existing bridges is based on the definition of a “structure regularity” which allows the estimation of whether the response of the real structure will be similar to that predicted in the preliminary design phase. The efficiency of the approach is shown in designing the isolation system for a highly irregular bridge.     

Exaptation and synanthropic insects: A diachronic interplay between biology and culture

Abstract

Since 1982, Stephen J. Gould and Elisabeth Vrba's concept of exaptation has been adopted, to varying degrees, by a number of biological and social science disciplines. However, it remains a missing term in the study of archaeologically recovered insect remains and entomologically related artefacts. Exaptation refers to the process by which a characteristic acquires a function for which it was not originally adapted. The application of Gould and Vrba's concept to the field of archaeoentomology could enhance our perception of past social, environmental, and climatic conditions as well as interactions. Herein, biological and technological examples of the enduring relationship between synanthropic insects and humans are explored using the concept of exaptation.     

Seaborne Ethnography and the Natural History of Man*

This paper examines intellectual interchanges between European theorists in the science of man and sailors, naturalists and artists on scientific voyages in Oceania during the century after 1750. I argue that travellers' narratives and ethnographic representations were not mere reflexes of dominant metropolitan discourses, but were also personal productions generated in the tensions and ambiguities of cross-cultural encounters. I identify countersigns of indigenous agency embedded in such materials and evaluate their trajectory from the interactions which provoked them, through varied genres and media of voyagers' representations, to their contorted appropriation by European savants. My examples are drawn from British and French accounts of visits to New Holland and Van Diemen's Land between 1770 and 1802. In this paper, Aboriginal Australians, especially Tasmanians, serve as synecdoche for the indigenous inhabitants of Oceania generally, using the regional term in its extended early 19th-century sense which encompassed the present Indonesia and Australia along with Papua New Guinea, Aotearoa/New Zealand and the Pacific Islands.     

Gender and Feminist Geography in Colombia

Abstract

The article explains how gender and feminist geography as a transversal analytical category to geography have been introduced recently in Colombia. At the beginning of the XXI century, in the geography department of Universidad Nacional de Colombia, the first undergraduate thesis to focus on the relationship between gender and processes of social construction of space was presented. Since then, the contributions of geographers and researchers from a feminist geographic perspective have contributed to the feminist geographical debates from their own trajectories. The contemporary geographical landscape in Colombia is linked with the transversal debates on feminisms and gender in social sciences, social movements and Latin-American feminisms. This networks and connections allows today a diversity of themes from the deconstruction of hegemonic spatial representations in different contexts, gender and conflicts related to territory and body, to some new approaches to technologies and virtual social interactions and their connotation in the construction of non-normative spatialities.     

The Consorts of King Wu and King Wen in the Bronze Inscriptions of Early Chou

Abstract

Daodejing is an essential text in Chinese culture. The number of its English translations exceeds a total of 112 editions. The first one was produced by John Chalmers, who was a Scottish missionary from London Missionary Society stationed in Hong Kong and Canton for a long period of time. Chalmers's close missionary colleague, James Legge, who was subsequently the first Professor of Chinese Studies at the University of Oxford, produced another translation. This paper aims at revealing the socio-cultural and intellectual processes behind the making of these two translations. In so doing, it discusses the differences in the two texts and explores the reasons for their differences.

Christian missionaries in China were the agents for the cultural interactions between China and the West. Not only did they bring the Christian message to China, but they also introduced the Chinese ideas through their translations and writings to their Western audience. This should be a fruitful and important topic for serious scholarship in both the studies in Sinology and in the history of translation.
