scholarly journals Report of magnetic experiments tried on board an iron steam-vessel, by order of the Right Hon. the Lords Commissioners of the Admiralty

This report commences with a description of the iron steam-vessel, the “Garryowen,” belonging to the City of Dublin Steam Packet Company, and built by the Messrs. Laird, of Liverpool. She is constructed of malleable iron, is 281 tons burthen, and draws only 5 1/4 feet water, although the weight of iron in the hull, machinery, &c. is 180 tons. This vessel was placed under the directions of the author, in Tarbert Bay, on the Shannon, on the 19th of October, 1835, for the purpose of investigating its local attractions on the compass. The methods which were adopted with that view are given ; together with tables of the results of the several experiments, and plans of the various parts of the Garryowen. The horizontal deflections of the magnetic needle at different situations in the vessel were observed, for the purpose of ascertaining the most advantageous place for a steering compass, and also for the application of Professor Barlow’s correcting plate : and the dip and intensity in these situations were, at the same time, noted.

Sir,—In pursuance of orders from the Lords Commissioners of the Admiralty, I proceeded to Ireland, taking with me the necessary instruments for ascertaining the deviation of the magnetic needle produced by the local attraction of an iron steamvessel, together with others for determining the dip, magnetic intensity, &c. Every facility for pursuing the inquiry directed by Their Lordships was afforded by Messrs. Laird, of Liverpool, who built the “Garryowen;" and the City of Dublin Steam Packet Company (through Charles W. Williams, Esq.) liberally offered the use of the above-named vessel, on the river Shannon, for the purpose of trying the necessary experiments; and I must not omit to mention in this place my obligation to Professor Barlow, from whom I received many valuable hints relative to the application of his correcting-plate previous to leaving London.

During the months of October and November 1835 a series of magnetic observations was made, under orders of the Lords Commissioners of the Admiralty, on board the iron steamship Garryowen by Commander Edward J. Johnson R.N. The results of Johnson's observations paved the way to Airy's solution to the crucial problem of compass management on board an iron ship.Johnson related in a paper in which he described his experiments, that he proceeded to Ireland taking with him the necessary instruments for ascertaining the deviation of the magnetic needle produced by the local attraction of an iron steam-vessel, together with instruments for measuring dip and magnetic intensity. Every facility was afforded him by the owners of the Garryowen, the City of Dublin Steam Packet Company, and by the builders of the vessel, Messrs. Laird of Liverpool.The Garryowen, built in 1833, was a paddle steamer of length 130 ft, breadth 21 ft 6 in and depth 11 ft. She was equipped with two engines each rated at 85 h.p. and her tonnage was 281 tons burden. She was fitted with four water-tight transverse bulkheads of wrought-iron ¼ in thick. Her hull and boilers were of malleable iron and the total weight of iron in her structure amounted to 180 tons.

The article examines the impact of the discourses concerning idleness and food on the formation of “production art” in the socio-political context of revolutionary Petrograd. The author argues that the development of the theory and practice of this early productionism was closely related to the larger political, social and ideological processes in the city. The Futurists, who were in the epicenter of Petrograd politics during the Civil War (1918–1921), were well acquainted with both of the discourses mentioned, and they contrasted the idleness of the old art with the dedicated labor of the “artist-proletarians” whom they valued as highly as people in the “traditional” working professions. And the search for the “right to exist” became the most important goal in a starving city dominated by the ideology of radical communism. The author departs from the prevailing approach in the literature, which links the artistic thought of the Futurists to Soviet ideology in its abstract, generalized form, and instead elucidates ideological influences in order to consider the early production texts in their immediate social and political contexts. The article shows that the basic concepts of production art (“artist-proletarian,” “creative labor,” etc.) were part of the mainstream trends in the politics of “red Petrograd.” The Futurists borrowed the popular notion of the “commune” for the title of their main newspaper but also worked with the Committees of the Rural Poor and with the state institutions for procurement and distribution. They took an active part in the Fine Art Department of Narkompros (People’s Commissariat of Education). The theory of production art was created under these conditions. The individualistic protest and “aesthetic terror” of pre-revolutionary Futurism had to be reconsidered, and new state policy measures were based on them. The harsh socio-economic context of war communism prompted artists to rethink their own role in the “impending commune.” Further development of these ideas led to the Constructivist movement and strongly influenced the extremely diverse trends within the “left art” of the 1920s.

A utopia do direito à cidade,  no  caso específico do Rio de Janeiro, começa, obrigatoriamente, pela  superação da visão dicotômica favela-cidade. Para isso, é preciso que os moradores da favela possam sentir-se tão cidadãos quanto os que têm moradias fora das favelas. A utopia do direito à cidade tem de levar a favela a própria utopia da cidade. Uma cidade que não se fragmente em oposições asfalto-favela, norte-sul, praia-subúrbio e onde todos tenham direito ao(s) seu(s) centro(s). Oposições que expressam muito mais do que diferenças de  localização e que  se apresentam recheadas de  segregação, estereótipos e  ideologias. Por outro  lado, o direito a cidade, como possibilidade histórica, não pode ser pensado exclusivamente a partir da  favela. Mas as populações  que aí habitam guardam uma contribuição inestimável para  a  construção prática  desse direito. Isso porque,  das  experiências vividas, emergem aprendizados e frutificam esperanças e soluções. Para que a favela seja pólo de um desejo que impulsione a busca do direito a cidade, é necessário que ela  se  pense como  parte da história da própria cidade  e sua transformação  em metrópole.Abstract The right  to the city's  utopy  specifically  in Rio de Janeiro, begins by surpassing  the dichotomy approach between favela and the city. For this purpose, it is necessary, for the favela dwellers, the feeling of citizens as well as those with home outside the favelas. The right to the city's utopy must bring to the favela  the utopy to the city in itself- a non-fragmented city in terms of oppositions like "asphalt"-favela, north-south, beach-suburb and where everybody has right to their center(s). These oppositions express much more the differences of location and present  themselves full of segregation, stereotypes and ideologies. On  the other  hand, the right to  the city, as historical possibility, can not be thought  just from the favela. People that live there have a contribution for a practical construction of this right.

The regulation of public space is generative of new approaches to gender nonconformity. In 1968 in Jakarta, the capital of Indonesia, a group of people who identified as wadam—a new term made by combining parts of Indonesian words denoting “femininity” and “masculinity”—made a claim to the city's governor that they had the right to appear in public space. This article illustrates the paradoxical achievement of obtaining recognition on terms constituted through public nuisance regulations governing access to and movement through space. The origins and diffuse effects of recognition achieved by those who identified as wadam and, a decade later, waria facilitated the partial recognition of a status that was legal but nonconforming. This possibility emerged out of city-level innovations and historical conceptualizations of the body in Indonesia. Attending to the way that gender nonconformity was folded into existing methods of codifying space at the scale of the city reflects a broader anxiety over who can enter public space and on what basis. Considering a concern for struggles to contend with nonconformity on spatial grounds at the level of the city encourages an alternative perspective on the emergence of gender and sexual morality as a definitive feature of national belonging in Indonesia and elsewhere.

Abstract The city of Granada is experimenting a big urban transformation, attending national and international commitments on clean air, energy efficiency and savings linked to greenhouse gases reduction strategies and sustainable development action plans. This situation constitutes a good scenario for new noise control approaches that take into account the sound variable and citizens empowering in urban design, such as the soundscape assessment of urban territory. In this way, soundscape tools have been used in Granada as a complementary method for environmental noise characterisation where traditional noise control techniques are difficult to be carried out or give limited results. After 2016 strategic noise map and in the preparation of the new noise action plan, the city came across a great acoustic challenge in a new area located outskirts characterised by growing urbanisation, still under development, the greatest legal protection because of sensitive teaching and hospital buildings and the greatest noise exposure from nearby ring-way supporting heavy traffic flow. As quiet urban areas are not characterised by the absence of noise but for the presence of the right noise, this research intended to provide the local administration with results and proposals to transform this conflict area in a pleasant or quiet urban place. Main results came from important and significative differences in morning and evening characterisation, as great differences appear in soundscape assessment over the day and along the soundwalk path, indicating the importance of time and local issues to adequately characterised citizens perception to be considered by administration in the development of strategies and effective noise control actions.

Abstract This essay attempts to capture the human rights implications of COVID-19, and responses to it, in the city of York (UK). Three human rights contributions are identified: ensuring that responses enhance dignity, the right to life, non-discrimination, and protect the most vulnerable; using human rights when balancing priorities and making difficult decisions; and optimizing the link between disease and democracy. The overarching aim is to localize and contextualize human rights in a meaningful way in the city, and thereby to provide meaningful guidance to the City Council and statutory agencies when implementing the difficult measures required by the pandemic, and to support civil society advocacy and monitoring. This work, led by the York Human Rights City (YHRC) network, illustrates the value of a localized ‘thick description’ of human rights and the multi-dimensional picture of challenges, innovations and solutions facilitated by such an approach.
