Using data from the UK Census of Production, including foreign ownership data, and information from UK industry input-output tables, this paper examines whether the intensity of transactions linkages between foreign and domestic firms affects productivity growth in domestic manufacturing industries. The implications of the findings for policies promoting linkages between multinational and domestic firms in the UK economy are outlined.

We are interested in the emergence of new markets. While the literature contains various perspectives on how such new markets come to be, the dynamics of the marketization process are less clear. This paper focuses on the development of stent technology and examines the activities characteristic of its emerging market. We identify four market ‘moments’: a mutable marketing moment prior to the point of disruption; two parallel moments at the point of disruption – internecine marketing between emergent competitors, and subversive marketing between those competitors and established actors; and finally, a civilized marketing moment. We conclude that emergent competitors operate two distinct strategies at the point of disruption. Also, legal activities are central to marketization dynamics during this period. In terms of process, while creative destruction may broadly describe the move from disruption to acceptance, there is a period of creative construction prior to disruption, when the new market is coming into being.

The Asian green mussel Perna viridis is tolerant to environmental stress, but its robustness varies between populations from habitats that differ in quality. So far, it is unclear whether local adaptations through stressinduced selection or phenotypic plasticity are responsible for these inter-population differences. We tested for the relevance of both mechanisms by comparing survival under hypoxia in mussels that were transplanted from an anthropogenically impacted (Jakarta Bay, Indonesia) to a natural habitat (Lada Bay, Indonesia) and vice versa. Mussels were retrieved 8 weeks after transplantation and exposed to hypoxia in the laboratory. Additional hypoxia tests were conducted with juvenile mussels collected directly from both sites. To elucidate possible relationships between habitat quality and mussel tolerance, we monitored concentrations of inorganic nutrients, temperature, dissolved oxygen, salinity, phytoplankton density and the mussels' body condition index (BCI) for 20 months before, during and after the experiments. Survival under hypoxia depended mainly on the quality of the habitat where the mussels lived before the hypoxia tests and only to a small degree on their site of origin. Furthermore, stress tolerance was only higher in Jakarta than in Lada Bay mussels when the BCIs were substantially higher, which in turn correlated with the phytoplankton densities. We explain why phenotypic plasticity and high BCIs are more likely the causes of populationspecific differences in hypoxia tolerance in P. viridis than stress-induced selection for robust genotypes. This is relevant to understanding the role of P. viridis as mariculture organism in eutrophic ecosystems and invasive species in the (sub)tropical world.

This article explores three national and local journalists’ experiences of reporting on child sexual exploitation by so-called “Asian street grooming gangs” in UK towns and cities, with a particular emphasis on journalists framing journalists. In response to coverage of a series of cases, journalists have been accused by academics, policymakers and rival media organizations of fixating on perpetrators’ ethnicity and creating distorted, racist media frames. Few, if any, studies have garnered practitioners’ perspectives on how framing occurs, so we interview three prominent journalists who have covered such cases in order to deepen our understanding of the processes and causative factors behind particular editorial angles. While offering only a snapshot view, our findings reveal these individual journalists to be caught at the nexus of a range of factors that impact upon their work, both internally and externally driven.

Esta obra, es producto de la investigación "Falencias en la aplicación de la normativa que trata de los derechos sociales, económicos y culturales de la población en situación de desplazamiento forzado en la ciudad de Medellín" realizada interdisciplinariamente por investigadores del Grupo de Investigaciones en Derecho Procesal, Grupo de Investigaciones Jurídicas de la Universidad de Medellín e Investigadores de la Personería de Medellín, con el apoyo logístico y administrativo de la Secretaría de Salud de Medellín. Este trabajo parte de un hecho evidente y es que los estudios jurídicos sobre esta problemática son escasos. Se formula la siguiente hipótesis central: "la población desplazada en Medellín no cuenta con una protección eficiente y efectiva de sus derechos básicos". Por ello se inicia la exploración, de manera juiciosa. Se establece, en primer lugar, el estado del arte en este tema, luego los derechos económicos, sociales y culturales que enmarcarían la actividad investigativa; se revisa y clasifica la jurisprudencia producida por la Corte Constitucional, los mecanismos de protección, la política pública en la cuidad y se determina la forma real de atención a la población desplazada.

Este trabalho tem o objetivo de propor uma investigação do espaço a partir do sujeito enquanto ser existente, do indivíduo psicológico; assim de uma análise do espaço a partir dos processos psicológicos, associados aos processos no espaço. Assim, pretende-se compreender o espaço a partir das demandas internas do homem, que o motivam à ação; dos indivíduos que coletivamente, em sociedade, imprime a ação no espaço, lócus da produção do homem; a fim de efetivamente alcançar a relação do homem no espaço. Busca investigar possibilidades na construção do saber geográfico, e na realização do ensino de geografia, dentro de análise dialética dos processos no espaço, intensificando a compreensão dos processos no espaço a partir do homem, dos processos psicológicos - aprofundando a crítica sobre a perversidade dos processos espaciais atuais, traduzidos principalmente no modelo atual de globalização. A partir da reflexão sobre a relação cidadania e educação, pretende-se realizar uma crítica a respeito da produção do espaço, do modelo de produção atual, e do papel da geografia enquanto ciência e ensino. A análise neste trabalho é realizada a partir do método dialético e com base em revisões bibliográficas.

Esta investigación tuvo como fin primordial hacer algunas consideraciones sobre los suelos y la vegetación del edificio volcánico del Barva. Para alcanzar este objeto fue imprescindible caracterizar el area a través de una serie de tipo climatico, botánico y edafico. En vista de la ausencia de material bibliográfico sobre el area de estudio, el trabajo presenta como particularidad la inclusión de un mapa de isotermas y un grafico de isoyetas diseñados y construidos exclusivamente para esta investigación , asi como exhaustivas comprobaciones en el Laboratorio de Suelos de la Facultad Ciencias de la Tierra y Mar y en el Ministerio de Agricultura y Ganaderia. A los resultados obtenidos mediante el análisis, les fue aplicado el diseño estadístico-matematico de Bloques al Azar. Las conclusiones a que se llegó, destacaron la relevancia de preservar el area como Reserva Biologica Nacional.ABSTRACTThe primary objetive of this investigation is to present considerations about the soil and the soil and the vegetation of the Barva volcanic edifice. To realize this objective, it was essential to characterize the area by mans of a series of climatic, botanic and edaphic studies.In view absence of bibliographic material about the study area, this study presents a peculiarity in the inclusion of an isotermic map and a graph of isoyeths designed and constructed exclusively for this type of investigations, as well as exhaustive comparisons in the soil laboratories of the Faculty of Earth and Sea Sciences and the Ministry of Agriculture. The statistc-mathematic diagram of random blocks was applied to the results obtained by means of the soil analysis. The developed conclusions emphasized the importance of preserving the zone as a national biologic reserve.
