Economic Integration and Similarity in Trade Structures

In this paper we look at the similarity of trade structures in an integrating area. In particular, we analyse the export flows toward the EU market of four of the so-called “accession countries" of Central and Eastern Europe by comparing them to those of the pre-2004 members of the European Union (EU15). From a methodological point of view, we evaluate the appropriateness of different classes of similarity indices - correlation indices and distance metrics - opting for the use of the Bray-Curtis semi-metric to assess changes in the trade similarity. We examine its evolution over time - from 1989 to 2001 - considering both self-similarity (how the export composition of a CEEC has changed with respect to the beginning of the transition process) and EU-similarity (if and how the export composition of a CEEC has changed with respect to the EU15 export composition). Finally, we use EU-similarity matrices to test if the dynamics of sectoral distribution of total exports of Poland, Hungary, Romania, and Bulgaria to the EU is related to the role acquired by processed trade in the 1990s. Using a nonparametric Mantel test we give evidence that: (1) processed trade is crucial in explaining changes in the overall structure of exports of transition countries, and (2) that greater economic integration in terms of trade flows and processing trade does not always lead to greater export similarity between the CEECs and the EU15 member States.EU, CEECs, Transition, Similarity, Nonparametrics

The volunteer tourist as 'hero'

Volunteer tourism is a rapidly growing form of tourism which has a weak conceptual basis and which is generally defined rather simply in terms of participants' actions while on holiday, ignoring elements such as reasons for participation, behaviour, and influencing forces. This article argues that an appropriate conceptual base for volunteer tourists is Campbell's 'Hero's Journey' and draws analogies between participants in volunteer tourism and the 'Hero' in Campbell's writings. The article discusses data on volunteer tourists, which reveals their self-expressed reasons for participating, and their specific situations. The data were collected by field research based on covert participation at an orphanage in Mexico. Volunteers interviewed revealed the traits explaining their participation in volunteer tourism that were similar to the characteristics and driving forces found in the participants on Campbell's 'Hero's Journey' and in medieval and classical myths. While participation in volunteer tourism may not match contemporary understanding of heroes and heroic behaviour, there is considerable similarity in reasons given by respondents for participating in the activity, and a conceptual model is developed to illustrate thi

The Most Influential Paper Gerard Salton Never Wrote

Gerard Salton is often credited with developing the vector space model (VSM) for information retrieval (IR). Citations to Salton give the impression that the VSM must have been articulated as an IR model sometime between 1970 and 1975. However, the VSM as it is understood today evolved over a longer time period than is usually acknowledged, and an articulation of the model and its assumptions did not appear in print until several years after those assumptions had been criticized and alternative models proposed. An often cited overview paper titled ???A Vector Space Model for Information Retrieval??? (alleged to have been published in 1975) does not exist, and citations to it represent a confusion of two 1975 articles, neither of which were overviews of the VSM as a model of information retrieval. Until the late 1970s, Salton did not present vector spaces as models of IR generally but rather as models of specifi c computations. Citations to the phantom paper refl ect an apparently widely held misconception that the operational features and explanatory devices now associated with the VSM must have been introduced at the same time it was fi rst proposed as an IR model.published or submitted for publicatio

There Is No Special Problem About Scientific Representation

In recent years, philosophers of science have devoted considerable attention to questions about scientific models, and particularly to the issue of how models can represent the world. We propose that scientific representation is best understood as a special case of a more general notion of representation, and that the relatively well worked-out and plausible philosophical theories of the latter are directly applicable to the scientific special case. Construing scientific representation in this way makes the so-called ``problem of scientific representation'' look much less interesting than it has seemed to many, and also suggests that some of the (hotly contested) debates in the literature are concerned with non-issues

A New Puzzle for Phenomenal Intentionality

Phenomenal intentionality theories have recently enjoyed significant attention. According to these theories, the intentionality of a mental representation (what it is about) crucially depends on its phenomenal features. We present a new puzzle for these theories, involving a phenomenon called ‘intentional identity’, or ‘co-intentionality’. Co-intentionality is a ubiquitous intentional phenomenon that involves tracking things even when there is no concrete thing being tracked. We suggest that phenomenal intentionality theories need to either develop new uniquely phenomenal resources for handling the puzzle, or restrict their explanatory ambitions

Knowledge-yielding communication

A satisfactory theory of linguistic communication must explain how it is that, through the interpersonal exchange of auditory, visual, and tactile stimuli, the communicative preconditions for the acquisition of testimonial knowledge regularly come to be satisfied. Without an account of knowledge-yielding communication this success condition for linguistic theorizing is left opaque, and we are left with an incomplete understanding of testimony, and communication more generally, as a source of knowledge. This paper argues that knowledge-yielding communication should be modelled on knowledge itself. It is argued that knowledge-yielding communication occurs iff interlocutors coordinate on truth values in a non-lucky and non-deviant way. This account is able to do significant explanatory work: it sheds light on the nature of referential communication, and it allows us to capture, in an informative way, the sense in which interlocutors must entertain similar propositions in order to communicate successfully
