Externality effects of information and communication technologies across country Borders

As information and communications technology (ICT) involves both traditional capital and knowledge capital, potential spillovers through various mechanisms can occur. We posit that ICT capital may boost productivity growth, not only in the home country, but also in other countries. In this paper, we provide empirical evidence of such spillovers using panel data on 37 countries from 1996 to 2004. Our results support the existence of ICT spillovers across country borders. Furthermore, we find that developing countries could reap more benefits from ICT spillovers than developed countries. This is particularly important for policy decisions regarding national trade liberalization and economic integration. Developing economies that are more open to foreign trade may have an economic advantage and may develop knowledge-intensive activities, which will lead to economic development in the long run.

Experiencing transnationalism at home:open borders and the everyday narratives of non-migrants

The normative migration rights literature has engaged with the situated experience of migration to a very limited extent, with particularly little attention paid to non-migrants living in receiving localities. This article argues that exploring the non-elite narratives of non-migrants provides valuable insights for normative theorising about migration rights. The discussion is illustrated with a description of research undertaken within rural migration-receiving communities in England, which shows how the narratives of non-migrants shape the experience of migration at a micro-level. This article discusses the implications of this research for normative theory in order to demonstrate the value of this methodological approach.

Shifting borders of European Union internal security:technology, externalisation and accountability

This edited volume analyzes recent key developments in EU border management. In light of the refugee crises in the Mediterranean and the responses on the part of EU member states, this volume presents an in-depth reflection on European border practices and their political, social and economic consequences. Approaching borders as concepts in flux, the authors identify three main trends: the rise of security technologies such as the EUROSUR system, the continued externalization of EU security governance such as border mission training in third states, and the unfolding dynamics of accountability. The contributions show that internal security cooperation in Europe is far from consolidated, since both political oversight mechanisms and the definition of borders remain in flux. This edited volume makes a timely and interdisciplinary contribution to the ongoing academic and political debate on the future of open borders and legitimate security governance in Europe. It offers a valuable resource for scholars in the fields of international security and migration studies, as well as for practitioners dealing with border management mechanisms.

A közgazdaságtan és a szociológia határán - az identitás-gazdaságtan által felvetett elméleti kérdések (On the borders of economics and sociology. Theoretical questions raised by identity economics)

A tanulmány az identitás-gazdaságtan megközelítését és az általa felvetett elméleti kérdéseket kívánja bemutatni. E tan kiinduló tétele George A. Akerlof és Rachel E. Kranton szerint az, hogy a közgazdaságtanban használt hasznosságfüggvénybe be kell emelni az emberek énképének és az ezzel kapcsolatos egyéni mérlegelésnek a szempontjait. Ezt az indokolja, hogy az emberek társadalmi csoportokhoz/kategóriákhoz tartoznak, amelyekhez normarendszer társul, azaz ha viselkedésükkel megsértik a normákat, akkor önképük sérül, és ezáltal csökken a hasznosságuk is. A tanulmányban bemutatjuk, hogy ez a szemlélet az embereket "túlszocializált" társadalmi szereplőkként mutatja be, akik kevéssé reflektálnak a helyzetükre. További kérdéseket vetnek fel az elmúlt években végzett szociálpszichológiai és viselkedés- gazdaságtani kísérletek, amelyek rámutatnak, hogy az identitás- gazdaságtani elmélet egyik alapját jelentő normák erősen függnek szituációs tényezőktől. _____ The paper introduces the approach of identity economics and the theoretical questions raised by its arguments. According to Akerlof and Kranton, individual identity and personal calculations in relation to this identity should be incorporated into the utility function applied in economics, so that people are placed in social categories that involve normative systems. In line with this, if their actions breach the social norms, this affects negatively their self-image, so in turn decreasing their utility. The paper argues that this approach presents humans as "overly socialized" social actors who do not reflect on their situation. Further questions could be raised by experiments in social psychology and behavioral economics conducted in recent years. The results highlight the fact that the norms which serve as the basis for the theory of identity economics depend strongly on the context and given situation.

Preparação e caracterização de biomateriais poliméricos para avaliação da viabilidade de uso como phantom biológico

The theoretical and experimental developments in the biomaterials area have been directly applied to different fields of Medicine (odontology, regenerative medicine and radiotherapy). These advances have focused both for diagnosing diseases such as for quantifying degrees of progression. From the perspective of these studies, biomaterials are being designed and manufactured for application in various areas of science, provided advances in diagnostic radiology, radiotherapy dosimetry and calibration of radiotherapy equipment. Develop a phantom from a biomaterial has become a great ally of medicine in the treat patients with oncological diseases, allowing better performance of the equipment in order to reduce damage to healthy tissue due to excessive exposure to radiation. This work used polymers: chitosan and gelatin, for making the polymeric structures and controlled for different types of production and processing, characterizing and evaluating the biopolymer by physical techniques (STL, SEM and DEI) and therefore analyze applicability as phantom mouse lung. It was possible to evaluate the morphology of biomaterials quantitatively by scanning electron microscopy associated with imaging technique. The relevance of this work focuses on developing a phantom from polymeric biomaterials that can act as phantom providing high image contrast when subjected to analysis. Thus, the choice of DEI technique is satisfactory since it is an imaging technique of X-ray high resolution. The images obtained by DEI have shown the details of the internal microstructure of the biomaterial produced which have ≈ 10 μm dimension. The phantoms had made density ranging from 0.08 a 0.13 g/cm3.

Tissue Equivalent Phantom Design for Optimization of a Coherent Scatter Imaging System

Scatter in medical imaging is typically cast off as image-related noise that detracts from meaningful diagnosis. It is therefore typically rejected or removed from medical images. However, it has been found that every material, including cancerous tissue, has a unique X-ray coherent scatter signature that can be used to identify the material or tissue. Such scatter-based tissue-identification provides the advantage of locating and identifying particular materials over conventional anatomical imaging through X-ray radiography. A coded aperture X-ray coherent scatter spectral imaging system has been developed in our group to classify different tissue types based on their unique scatter signatures. Previous experiments using our prototype have demonstrated that the depth-resolved coherent scatter spectral imaging system (CACSSI) can discriminate healthy and cancerous tissue present in the path of a non-destructive x-ray beam. A key to the successful optimization of CACSSI as a clinical imaging method is to obtain anatomically accurate phantoms of the human body. This thesis describes the development and fabrication of 3D printed anatomical scatter phantoms of the breast and lung.

The purpose of this work is to accurately model different breast geometries using a tissue equivalent phantom, and to classify these tissues in a coherent x-ray scatter imaging system. Tissue-equivalent anatomical phantoms were designed to assess the capability of the CACSSI system to classify different types of breast tissue (adipose, fibroglandular, malignant). These phantoms were 3D printed based on DICOM data obtained from CT scans of prone breasts. The phantoms were tested through comparison of measured scatter signatures with those of adipose and fibroglandular tissue from literature. Tumors in the phantom were modeled using a variety of biological tissue including actual surgically excised benign and malignant tissue specimens. Lung based phantoms have also been printed for future testing. Our imaging system has been able to define the location and composition of the various materials in the phantom. These phantoms were used to characterize the CACSSI system in terms of beam width and imaging technique. The result of this work showed accurate modeling and characterization of the phantoms through comparison of the tissue-equivalent form factors to those from literature. The physical construction of the phantoms, based on actual patient anatomy, was validated using mammography and computed tomography to visually compare the clinical images to those of actual patient anatomy.

The emergence of borders: moral questions mapped out

In this paper, we examine the extent to which the concept of emergence can be applied to questions about the nature and moral justification of territorial borders. Although the term is used with many different senses in philosophy, the concept of “weak emergence” - advocated by, for example, Sawyer (2002, 2005) and Bedau (1997 ) - is especially applicable, since it forces a distinction between prediction and explanation that connects with several issues in the discussion of territory. In particular, we argue, weak emergentism about borders allows us to distinguish between (a) using a theory of territory to say where a border should be drawn, and (b) looking at an existing border and saying whether or not it is justified (Miller, 2012; Nine, 2012; Stilz, 2011). Many authors conflate these two factors, or identify them by claiming that having one without the other is in some sense incoherent. But on our account - given the concept of emergence - one might unproblematically be able to have (b) without (a); at the very least, the distinction between these two issues is much more significant than has often been recognised, and more importantly gives us some reason to prefer “statist” as opposed to “cultural” theories of territorial borders. We conclude with some further reflections on related matters concerning, firstly, the apparent causal powers of borders, and secondly, the different ways in which borders are physically implemented (e.g., land vs. water).

Nagaland: Borders, Boundaries, Belonging: Contested spaces and disputed narratives

In 2011 I travelled to three of the ‘Seven Sister’ states of old Assam, Nagaland, Meghalaya & Assam. My journey to this remote and politically sensitive region, bordering Chinese occupied Tibet, Bangladesh and Myanmar was prompted by my father’s experiences in the region during WW2 in the Burma Campaign and brought into sharp relief on-going themes in my work, the impact the past has on the present, the relationship of time and place, identity and memory and the transcultural experiences caused by war, colonisation and migration. The drawings I made on location, the objects I collected and the notes and photographs I took formed the basis of the bookwork: NAGALAND borders boundaries belonging. When making the finished work the material quality of the object and the processes by which it was made become very important. The historical resonance of the medium and the time consuming nature of the process reflect the embedding of form and idea, and paid homage to the material culture of the Naga hill tribes. The bookwork was hand-bound, handset and printed by letterpress. Some spreads were printed in 6 colours and the book took over a year to produce. I see my practice as echoing that of generations of Lady travellers; embracing the need to journey, be in a liminal space, to have a plan but not be afraid to divert from it. To be alone, take a sketchbook and make images is, for me, the definition of the itinerant illustrator; one who travels widely in geographic space, visual forms and ideas, in order to get lost and find the unlooked for.
