The Branches of Large Electricity Companies in Portugal: From Trade to the Transfer and Adaptation of Technology (20th Century)

In the last decade of the 19th and first decades of the 20th century there was a movement of capital and engineers from the central and northern Europe to the countries of southern Europe and other continents. Large companies sought to obtain concessions and establish branches in Portugal, favouring the circulation of technical knowledge and transfer of technology for Portuguese industry. Among the various examples of the representatives of foreign companies in Portugal we find Jayme da Costa Ltd. established in 1916 in Lisbon, which was a branch of the Swedish company ASEA, as well as STAAL, ATLAS DIESEL (Sweden), Landis & GYR (Switzerland), Electro Helios, etc.. Another example is EFACEC a company founded in 1948 in Porto, that was a partnership between the Portuguese company CUF – Companhia União Fabril, and ACEC – Ateliers de Constructions Électriques de Charleroi and a small entreprise Electro-Moderna Ldª. This enterprise started the industrial production of electric motors and transformers, and later on acquired a substantial share of the national production of electrical equipment. Using Estatística das Instalações Elétricas em Portugal (Statistics on Electrical Installations in Portugal) from 1928 until 1950 we can identify the foreign enterprises acting in the Portuguese market: Siemens, B.B.C, ASEA, Oerlikon, etc. We can also establish a relationship between the development of the electric network and the growth of production and consumption of electricity in the principal urban centres. Finally we see how foreign firms were a stimulus to the creation of national enterprises, especially those of small scale, in Portugal.

Assessing Household Food Waste in Italy: A Methodology for Detecting Drivers and Quantities

It has been estimated that one third of edible food destined for human consumption is lost or wasted along the food supply chain globally. Much of the waste comes from Global North, where consumers are considered as the bigger contributors. Different studies tried to analyze and estimate the Household Food Waste (HFW), especially in UK and Northern Europe. The result is that accurate studies at national level exist only in UK, Finland and Norway while no such studies are available in Italy, except for survey- based researches. Though, there is a widespread awareness that such methods might be not able to estimate Food Waste. Results emerging from literature clearly suggest that survey estimate inferior amounts of Food Waste as a result, if compared to waste sorting and weighting analysis or to diary studies. The hypothesis that household food waste is under-estimated when gathered through questionnaires has been enquired into. First, a literature review of behavioral economics and heuristics has been proposed; then, a literature review of the sector listing the existing methodologies to gather national data on Household Food Waste has been illustrated. Finally, a pilot experiment to test a mixed methodology is proposed. While literature suggests that four specific cognitive biases might be able to affect the reliability of answers in questionnaires, results of the present experiment clearly indicate that there is a relevant difference between how much the individual thinks to waste and he/she actually does. The result is a mixed methodology based on questionnaire, diary and waste sorting, able to overcome the cons of each single method.

A Review: Livestock On-Station and On-Farm Trial

Scientist working in international livestock research are expected to be familiar with an interdisciplinary systems approach, and to work in multidisciplinary teams. The argument for this approach is that (1) discipline specialists are not equipped to understand the relationships between the components they focus on and the systems as a whole, (2) if the specialist operates in isolation from the other discipline, he/she is operating in isolation from the system and so the results may be irrelevant or, if applied, actually have a deleterious effect on the systems, (3) therefore, the specialist must understand the system through a  systems approach, a systems person, or the activities of a team. Applicants hoping to work in international livestock research are expected to have had project experience in the tropics, where the environment, culture, facilities and infrastructure  may be very different from that in Northern Europe. The purpose of this course is to familiarize student with the  multidisciplinary or interdisciplinary systems approach and to prepare them for their field projects in the tropics.

Creation of temporary ponds for amphibians in northern and central Europe

More than 4000 ponds have been created or restored in Denmark since 1985 as part of a large-scale pond-digging programme to protect endangered amphibians in particular and pond flora and fauna in general. Most ponds are created on private land with public financing. The programme was triggered by, among other factors, a drastic decline in amphibian populations in Denmark between 1940 and 1980. However, in recent years there has been an increased awareness in Denmark that temporary ponds are important for the conservation of some of the most rare amphibian species, such as fire-bellied toad Bombina bombina, natterjack toad Bufo calamita and green toad Bufo viridis. Other rare species such as moor frog Rana arvalis and European tree frog Hyla arborea also benefit from temporary ponds. The last 15 years of work on the conservation of endangered species and their habitats has resulted in a last-minute rescue and a subsequent growth in the size of most Danish populations of fire-bellied toad and green toad; some populations of the relatively more common natterjack toad have also increased. The creation of temporary ponds plays an important role in the success of these three species. The creation of ponds to help restore viable populations of the most rare amphibians has not been easy. To study the conditions that may need to be created, Danish herpetologists searched for areas with temporary ponds that had good water quality, natural hydrological conditions and a management regime influenced by traditional agricultural methods. The paper gives an overview of pond creation and restoration projects in Denmark and Poland and their significance for amphibian diversity.

High-resolution stratigraphy of the northernmost concentric raised bog in Europe: Sellevollmyra, Andoya, northern Norway

From the Sellevollmyra bog at Andoya, northern Norway, a 440-cm long peat core covering the last c. 7000 calendar years was examined for humification, loss-on-ignition, microfossils, macrofossils and tephra. The age model was based on a Bayesian wiggle-match of 35 C-14 dates and two historically anchored tephra layers. Based on changes in lithology and biostratigraphical climate proxies, several climatic changes were identified ( periods of the most fundamental changes in italics): 6410-6380, 6230-6050, 5730-5640, 5470-5430, 5340-5310, 5270-5100, 4790-4710, 4890-4820, 4380-4320, 4220-4120, 4000-3810, 3610-3580, 3370-3340 ( regionally 2850-2750; in Sellevollmyra a hiatus between 2960-2520), 2330-2220, 1950, 1530-1450, 1150-840, 730? and c. 600? cal. yr BP. Most of these climate changes are known from other investigations of different palaeoclimate proxies in northern and middle Europe. Some volcanic eruptions seemingly coincide with vegetation changes recorded in the peat, e.g. about 5760 cal. yr BP; however, the known climatic deterioration at the time of the Hekla-4 tephra layer started some decades before the eruption event.

Celtic nationalism and supranationalism: comparing Scottish and Northern Ireland party responses to Europe

This article explores how stateless nationalist parties in the ‘Celtic periphery’ of Scotland and Northern Ireland have used Europe to advance their territorial projects. Despite vastly different historical, political and social contexts, the Scottish National Party and Northern Ireland's Social Democratic and Labour Party have both advanced a pro-European, social democratic discourse that emphasises the importance of Europe as a framework for constitutional reform and shared sovereignty. However, in recent years the parties have diverged on Europe. While the SDLP has continued its principled commitment to further integration, the SNP has articulated an increased criticism of the supranational project. This divergence in party attitudes reveals the extent to which the pro-European dimension of Celtic nationalism is ideological or opportunistic.

Malthusian Dynamics in a Diverging Europe: Northern Italy, 1650–1881

Recent empirical research questions the validity of using Malthusian theory in preindustrial England. Using real wage and vital rate data for the years 1650–1881, I provide empirical estimates for a different region: Northern Italy. The empirical methodology is theoretically underpinned by a simple Malthusian model, in which population, real wages, and vital rates are determined endogenously. My findings strongly support the existence of a Malthusian economy wherein population growth decreased living standards, which in turn influenced vital rates. However, these results also demonstrate how the system is best characterized as one of weak homeostasis. Furthermore, there is no evidence of Boserupian effects given that increases in population failed to spur any sustained technological progress.
