<p>The Grand Avenue Pedestrian Bridge spans 85m from a park and residential neighborhood to a developing waterfront district that is 24m below. The bridge carries sewer, storm, and water utilities over rail lines and a highway while passing under power lines. The bridge’s east landing is on a landslide prone steep slope. On the west the bridge lands on a new concrete stair and elevator tower that rests on soil that is regularly infil- trated with seawater.</p><p>The design concept uses the constraints of the project to create a unique moment that is both utilitarian and unexpected. By sloping the truss to drop 4.8% towards the west, a set of accessible ramps are created on the top, side, and interior of a box-truss style bridge. Traversing 7m of elevation through accessible paths allowed the design team to minimize the height of the elevator and therefore moment into the foundations, critical for a site that is seismically active and located in seawater infiltrated soil.</p><p>Material choices for the bridge and throw barrier were based on considerations of durability and mainte- nance. Weathering steel is used for the primary truss members, painted steel for members located under the deck, and bare aluminum panels with a custom CNC cut perforation form the guardrail and throw barrier. All of the elements come together as a unified experience.</p>

The Hill

In 1946 a visit to the barrow, which lies on the edge of the western scarp of Chinnor Common, and a cursory examination of the adjoining area, cultivated during the war, resulted in finds of pottery and other objects indicating Iron Age occupation. The site lies on the saddleback of a Chiltern headland, at a height of about 800 ft. O.D. Two hollow ways traverse the western scarp, giving access to the area from the Upper Icknield Way, which contours the foot of the hill, then drops to cross the valley, passing some 600 yards to the north of the Iron Age site of Lodge Hill, Bledlow, and rising again continues northwards under Pulpit Hill camp and the Ellesborough Iron Age pits below Coombe Hill. The outlook across the Oxford plain to the west is extensive, embracing the hill-fort of Sinodun, clearly visible some fourteen miles distant on the farther bank of the Thames. The hollow way at the north-west end of the site leads down to a group of ‘rises’ hard by the remains of a Roman villa, and these springs are, at the present day, the nearest water-supply to the site.

The Horotiu Paa Bridge, also known as the Karapiro Gully Bridge is the largest weathering steel bridge in New Zealand. Construction of the bridge was recently completed in November 2015. The bridge is part of the Cambridge section of the Waikato Expressway in New Zealand. The Waikato Expressway is one of the seven state highways, named the Roads of National Significance, identified by the government as essential to New Zealand's economic prosperity. The bridge spans over the Karapiro Gully with a total length of 200m, consisting of four 50m long equal spans and is 24m wide, servicing 4 lanes of traffic.<p> This paper discusses the design development, key design aspects, innovations and technical challenges for the design of the Horotiu Paa Bridge.

Theology Of Liberation

The liberation of black humanity has been an area of scholarly reflection by black theologians and the black consciousness communities. The constructs of oppression such as race, class and sexism amongst others have been critiqued in the quest for liberation of a fragmented black humanity. In this article, this quest for liberation happens within ubuhlanti [kraal], a site for which Vuyani Vellem is ‘like a hermeneutical circle, where the mediations of the bonds of spheres and the instantiation of their life take place’. By looking at a fragmented black humanity and black women’s experiences, we posit that no western framework could ever be representative of those bodies, ubuhlanti becomes our solution as a heuristic device and symbol of a communication of the efficacy of integrated life. From a womanist perspective, ubuhlanti decentres the West. Ebuhlanti Amandla ngawethu [power belongs to us], as black women and men dialogue issues that affect black humanity. The whole proposition of this dialogue ebuhlanti is animated by our lived experiences, which already offer alternatives for us to decentre.Contribution: Premised by the lived experiences of black humanity in their quest for liberation, this paper contributes in the dewesternising discourse by presenting alternative epistemologies and spiritualities. A womanist dialogue with black theology of liberation ebuhlanti, a decolonising and decentring praxis for the liberation of black humanity is our solution as blacks.

Conservation Measures

SummaryCollisions with power lines represent an important mortality factor for Great Bustards Otis tarda throughout the distribution range of the species. This study evaluates the success of two conservation measures implemented in the West-Pannonian distribution range to reduce the number of power line collision casualties: (1) extensive underground cabling of 43.1 km power lines, and (2) marking of 89.7 km power lines starting in 2005 and 2006, respectively. The mortality rate of Great Bustards in our study area (covering 686.5 km2) decreased significantly between 2002 and 2011, predominantly caused by reduced mortality due to power line collisions. Univariate tests indicate that underground cabling and power line marking significantly decreased power line collision casualties. Generalised linear models (GLMs) highlighted the prominent effect of underground cabling. Our results indicate that five years after underground cabling and marking of power lines within core areas of the West-Pannonian distribution range of the Great Bustard, the population already benefited through a significantly decreased mortality rate. Both conservation measures most likely contributed strongly to the rapid recovery of the West-Pannonian Great Bustard population observed within the last decade.

This chapter focuses on Trakhtemirov, one of the most important ancient settlements of the Early Iron Age in the Ukraine. During the ancient period, the trade routes and caravans met at Trakhtemirov which was situated over the three crossing points of the Dneiper. Its location on the steep heights assured residents of Trakhtemirov security of settlement. On three sides it was protected by the course of the Dnieper while on the other side it was defended by the plateau of the pre-Dneiper elevation. The ancient Trakhtemirov city is located around 100 km below Kiev, on a peninsula which is jutted into the river from the west. Trakhtemirov in the Early Iron Age was important as it was the site of the Cossack capital of Ukraine. It was also the site of the most prestigious artefacts of the Scythian period and a site for various items of jewellery, tools and weaponry. The abundance of artefacts in Trakhtemirov suggests that the city is a central place among the scattered sites of the middle course of the Dneiper.

The article looks at Ikhwanweb, the English website of the Egyptian Muslim Brotherhood (MB), from its early days and through the years before the 25th January revolution. The archive is used as a theoretical concept to capture both the symbolic and material struggles that the MB faced while trying to articulate its political vision. As a nodal point where power and knowledge intersect, the concept of the archive was first theorized by Foucault and Derrida. Ikhwanweb is examined as a digital archive, a site for both knowledge and memory production. The first section deals with the main analytical concept; the second tells the troubled history of the material infrastructure required to run the website. Then two main threads are identified and examined. The need to distantiate the organization from political violence and that of reaching out ‘the West’ shaped the content of Ikhwanweb. The website also allowed the group to interact directly with policy-making circles and research institutions. Can this be said to be part of that process Bayat calls post-Islamism? The concluding section reflects on this question and suggests a more ambivalent picture.

Of Greece

The peloponnesus came so near to being a true island (Island of Pelops) that the neck of land (FIG. I) which joins it to the northern half of the Greek peninsula is less than five miles wide. This became a natural crossroads of the Greek world. Several routes converging on this landbridge connected the Peloponnesus with the rest of Greece. Communications by sea between the east and the west, through the Saronic and the Corinthian Gulfs, were interrupted by the Isthmus, and attempts were made early to pierce or overleap the barrier. The southern sea-lane encircling the Peloponnesus was much longer, and weather conditions made the journey hazardous. For this reason cargoes were unloaded at the two harbours, Kenkreai on the Saronic and Lechaion on the Corinthian Gulf, and carried by land across the Isthmus. Naval vessels, and perhaps the empty freight carriers, were transported over a paved roadway called Diolkos. The western end of this portage has long been recognized on the Peloponnesian side of the Corinth Canal, and recently longer stretches of pavement have been laid bare on both sides of the Canal. The Diolkos here did not run straight but ascended the steep slope in great sweeping curves (FIG. I and PLATE IX (c) ). The pavement has a width of 3-50-5 m. and is made with large poros blocks well fitted together. Two deep ruts, 1-50 m. apart, show that the ships were hauled on wheeled cradles, not on rollers, as was formerly assumed. The excavation, conducted by the Archaeological Service of the Greek Government, is still in progress, and the exact course across the Isthmus will not be known before this work is completed.

Cavanaugh Mound (3SB3, also known as Etter's Mound, Jones Mound, Site Zeta, and occasionally misspelled Cavenaugh) is a largely intact Late Prehistoric platform mound on the Arkansas River just east of the Oklahoma border, about 14 km from the Spiro Mounds complex. The site is situated on a high terrace above the Arkansas River as it runs between the Ouachita Mountains to the south and the Ozarks to the north. The Poteau River enters the Arkansas River floodplain just west of Cavanaugh, creating one of the widest stretches of bottomland in the region. The area immediately around Cavanaugh Mound is now a residential neighborhood in the city of Fort Smith, and the mound itself is in a tiny lot with a church to the south, a trailer park to the east (named Indian Mounds Trailer Park), and a row of houses to the west. At about 60 m across and 9 m high, Cavanaugh Mound is one of the largest, if not the largest, prehistoric mound in the region. Very little has been published concerning this site, however, and very little formal archeological work has been done there. This article is partly intended to call attention to Cavanaugh Mound, and to compile all reports and descriptions of the mound in one publication. The first part of the article is therefore mostly descriptive. I also offer some tentative interpretations of the site and its possible relationship to the nearby Spiro and Skidgel sites. The size , shape, and stratigraphy of the mound all indicate that it was constructed and used in a manner similar to other Caddoan era platform mounds in the Arkansas River valley. The mound appears to be alone on the landscape, not connected to a group of surrounding mounds and not located within or near a contemporaneous settlement. It overlooks the Poteau/ Arkansas River bottoms to the west and was probably visible from both the Spiro and Skidgel sites in prehistoric times.

Place And Identity

This paper activates a mode of spatial inquiry into Australia’s identity through an analysis of a number of frames through which the passage and interdiction of boats off the coast of the nation may be viewed. In particular, I explore the way in which Australia’s paradoxical geographical location as South of both the West and Asia play a key role in affixing the horizon within which a conception of the nation and its relationship with the world was – and continues to be – defined and shaped. Moreover, I not only critically probe the constitutive fears and anxieties that underlie bounded conceptions of the trope of the South, but also to examine how such a trope can articulate itself as a site of exchange and negotiation, a distinctive borderland that engenders new cartographies of difference and belonging in an increasingly globalised and interconnected world. I show how these frames overlap and converge on the wider questions of space, place and identity at the very moment when the process of globalisation and migration has done so much to shake any certainties about Australia’s identity as a geographically distinct and spatially bounded nation-state. In so doing, they represent crucial sites for articulating and enacting a transcultural politics of mobility and spatiality that attends to the ways in which the trope of the South may been imagined not as a sphere of containment or an enclaved territory, but as an evolving cartography, the shifting outlines of which opens up new horizons of possibility for rethinking the spatial and temporal coordinates of Australia in a globalizing world.
