Visigothic Jewellery: A Technical Study of Glass Used as Gems in Belt Buckles from a Spanish Necropolis

In this work, we studied coloured and colourless glass used as gems in Visigothic buckles possibly originating from the necropolises of Torredonjimeno, Duraton or Castilltierra in Spain. Scanning electron microscopy (SEM) with energy‐dispersive analysis (EDS) and observations made with an optical microscope in reflected and transmission mode were performed in order to establish the composition, origin of the colour and decay process of these glass pieces. The chemical analysis of ancient glass can provide relevant information regarding the manufacturing approach used during a specific period. The results revealed the presence of various transition metal elements used as chromophore elements, as well as some metallic backing foils used to improve the colour of pieces of almost colourless glass.     

Poverty Reduction and Good Governance: Examining the Rationale of the Millennium Development Goals

Whilst the deadline for achieving the Millennium Development Goals (MDGs) looms large, the outcomes so far have been mixed. This article examines the policy logic that ‘good governance’ leads to poverty reduction, which has been adopted by international agencies in pursuit of the MDGs. This causal relationship is examined through an empirical panel‐data estimation using Worldwide Governance Indicators and the poverty headcount ratio in ninety‐eight countries. The empirical evidence does not support the hypothesis that good governance leads to poverty reduction. Good governance alleviates poverty only in middle‐income countries, not in least developed ones. These findings point to the necessity to devise policies that address poverty directly, rather than through indirect instruments, and highlight the urgent need to address structural inequality in developing countries.     

THE DETERMINANTS OF LOCALIZATION AND URBANIZATION ECONOMIES: EVIDENCE FROM THE LOCATION OF NEW FIRMS IN SPAIN

The objective of this paper is to analyze why firms in some industries locate in specialized economic environments (localization economies) while those in other industries prefer large city locations (urbanization economies). To this end, we examine the location decisions of new manufacturing firms in Spain at the city level and for narrowly defined industries. First, we estimate firm location models to obtain estimates that reflect the importance of localization and urbanization economies in each industry. Then, we regress these estimates on industry characteristics related to the potential importance of labor market pooling, input sharing, and knowledge spillovers. Urbanization effects are high in knowledge‐intensive industries, suggesting that firms locate in large cities to benefit from knowledge spillovers. We also find that localization effects are high in industries that employ workers whose skills are more industry‐specific, suggesting that industries locate in specialized economic environments to share a common pool of specialized workers.     

The Issue of Citizenship for the Bidun Minority in Kuwait after the Arab Spring

Kuwait is a country in which there are many tribes but it is the al‐U'zam tribe which is very dominant and influential in local politics and the economy, in contrast to the other tribes in Kuwait who are recognized by the state as being equal, but have little influence in these things. The Bedouin tribes, such as the Bidun society in Kuwait, who have been excluded from nationality and citizenship and thus have no influence, are an exception. The Kuwaiti government claims that the Bidun themselves gave up these rights so as not to be part of the Kuwaiti state and this has resulted in the Kuwaiti government not granting them any formal economic, political, or social rights. Because of this, the Bidun have had to fight for their rights for decades since the formal establishment of an independent Kuwait in 1961. This article wishes to discuss whether the question of the Kuwaiti refusal to recognize the Bidun as citizens is because of geostrategic reasons, because of the fear of creating a precedent that might lead to the inclusion of other tribes into the Kuwaiti state, or because this is a traditional political strategy for dealing with politically weak tribes.     

Unsafe drinking water quality in remote Western Australian Aboriginal communities

Chronic kidney disease (CKD) is important in the fields of public health and health geography because of its heavy burden on the health system and high cost of treatment in its advanced stages. The causes of CKD are associated with diabetes and hypertension, but in some parts of the world, the disease occurs in the absence of these factors. Researchers identify this condition as CKD of “unknown” causes (CKDu). CKDu is a multi‐factored health problem and one suspected causal factor is contaminated drinking water. The disease occurs globally but is found in particularly high concentrations among people of certain ethnic and disadvantaged social groups living in very different locations around the world. CKD has become endemic in Western Australia where hospital admissions for Aboriginal people requiring renal dialysis or treatment for diabetes are much higher than for the general population. The possible proportions of CKDu cases among the CKD patients are unknown. This study examines the drinking water quality among communities such as these. Water chemistry analysis in these areas indicates that the nitrate and uranium content greatly exceed officially recommended levels. Most of these communities rely on raw groundwater to supply their domestic needs, and it is very likely that the people are unwittingly ingesting high levels of nitrates and uranium, probably including uranyl nitrates. Very few such remote communities have access to treated drinking water, and cost‐effective water treatment systems are required to provide potable water at the local scale.     

Pits,mounds, and vernal ponds in a Tasmanian subalpine grassland

Falling trees commonly turbate soils in primary forest, creating characteristic edaphic patterns related to pit and mound topography. Vernal ponds with associated mounds were observed in mineral soils on a treeless plain in subalpine Tasmania, Australia. The hypothesis that paired ponds and mounds on the plain originated as pit and mound features in forests that were later destroyed by fire was tested by comparing the soils and landforms caused by recent tree falls in adjacent forest with those on the plain. The soil characteristics, orientations, and dimensions of the ponds and mounds were consistent with a tree fall origin, although rare secondary ponds on the tops of mounds may derive from the burrowing activities of the medium‐sized marsupial, Vombatus ursinus (common wombat). The characteristics of pond and mound soils suggested that most were hundreds to thousands of years old, with the ponds persisting because of differences in deflation, deposition, and organic matter formation between themselves and adjacent persistently dry land.
