Abstract:
Big Tail Elephant Working Group (daweixiang gongzuo zu, hereafter BTE) is synonymous with the city of Guangzhou and the surrounding Pearl River Delta. Formed in 1991, the group is most closely associated with the artists Chen Shaoxiong (1962–2016), Liang Juhui (1959–2006), Lin Yilin (1964–) and Xu Tan (1957–). This article re-examines BTE artists’ practice from 1991 to 1994 and argues that the artist’s performing body provides the critical lens through which to understand BTE artists’ work during this time. Acknowledging that the experience of BTE’s work was primarily physical, embodied and pe

For example, BD allows for the analysis of actual (online) behavior and the analysis of networks on a grand scale. The sheer volume and variety of data allow for the detection of rare patterns and behaviors that would otherwise go unnoticed. However, there are al

Abstract:
This chapter examines how, given the historical realities that have built the current structure of the craft beer industry in the United States, we today see a structure that is itself racialized, gendered, and exclusionary. The systematic erasure of black and brown practices of brewing and drinking in early America; the creation and solidification of pubs and taverns, and the subsequent establishment and legal consecration of such spaces as 'white' establishments; the construction and solidification of the three-tiered distribution system that defined the oligopolistic beer structure that launched the big beer families; and all the way through the signing of the Homebrewers Act in 1978 — all these things have contributed to and solidified this structure. It is worth interrogating how it is that individuals have gotten and contemporarily get into the positions within the three-tiered system itself. The structure itself is one thing; the bodies within that structure are another, having the potential to either challenge the structural realities and/or to build the culture and symbolic violence that continues to actively exclude people of color. The chapter then lays out the social structure of becoming a brewer, a beer representative/distributor, and a consumer — the three parts of the three-tiered distribution system.

Abstract:
In 2004, the amazing ‘Flying Phil’ Rabinowitz broke the world 100 m sprint record for a centenarian, setting a time of 30.86 s and beating the previous world record time by over 5 s. Despite this impressive statistic, most 20 and 30 year-olds can readily run at these speeds when dashing for a bus, and the overall world record for 100 m currently stands at 9.69 s (set by Usain Bolt at the age of 21). Age-related degeneration in bodily function is familiar to all of us, and is known as ‘senescence’, or more colloquially, as ‘ageing’. Of course, this loss of physiological functioning not only impairs our ability to run: as individuals get older they typically experience an increase in the likelihood that they will die, and also a decrease in fecundity. The incidence rates of cancers and heart attack, for example, are considerably higher in older than in younger individuals. For these reasons, ageing has been dubbed ‘the most potent of all carcinogens’, but it has also long been considered as one of the world’s worst diseases (‘senectus enim insanabilis morbus est’—a sickness for which there is no cure). . . . Live long and prosper? . . . Organisms die for all sorts of reasons. They may get run over by a bus, they may be eaten by a predator, or they may succumb to a lethal disease. However, even if individuals survive all of these ‘extrinsic’ challenges, then the odds are that they will begin to experience the signs of senescence. While being eaten by a predator is unfortunate, it is also eminently understandable as a cause of death. Natural selection will tend to act on individuals to reduce the likelihood of this extrinsic mortality (for instance, by promoting higher vigilance or the development of some form of defence) but death from accidents, predators, and parasites cannot be completely avoided. Ageing, however, poses much more of a dilemma for evolutionary biologists. In particular, one might expect that those individuals who managed to slow down the ageing process would leave more offspring, so that natural selection would favour extreme longevity.

This chapter discusses the incremental improvements of Dublin in luminosity. The chapter notes that the Irish capital entered the age of gas lighting in the 1820s (although Dublin in 1825 was ahead of most big cities outside Britain), and gas installation was underway in Drogheda, Cork, Waterford and Limerick's Newtown Pery. But as high streets became brighter, many houses in older neighbourhoods, particularly in the southern cities, were darkened. The chapter examines its specific cause — the window tax, an old and unpopular levy in England, which had been introduced into Ireland in 1799 as a wartime measure. It then turns to analyze post-war complaints about taxation, and highlight the most tangible legacy of the post-war crisis in Dublin — the Mendicity Institution, which established to document, clothe, feed and employ able-bodied beggars on the capital's streets. The chapter illustrates the Irish manufacture of cotton, and the economic future of southern and western cities in terms of food processing and alcohol production.

Abstract:
Public utilities have been at the very centre of economic and social development of countries. Until the last decades, they were almost exclusively undertaken by public authorities. From the 1980s, they have been subject to liberalisation in many countries. Liberalisation of electricity means that the segments which are vertically integrated are unbundled and opened to private sector through privatisations. However, since the transmission and distribution segments are networks that exhibit severe natural monopoly characteristics, they should be either owned and operated by public bodies or regulated by independent regulatory authorities to protect consumer interest. In Turkey, the liberalisation process for the public utilities has begun in 1990s, but posed many problems at administrative and juridical stages. Lately, the legislative framework which is designed to be compatible with global standards has been completed. But at economic stage, we can easily observe the power of big companies and holdings outweigh the power of public authorities and counteract the public interest.

Across the twentieth century, an international network of thinkers has created an astounding vision of human movement into the cosmos. Everything done in space was first anticipated by these space expansionists, but only tiny parts of their vision have been realized. Space expansionism is the ideology of the global pro-space movement and offers a Big History narrative of the human past, present, and future, centered on technological advance and habitat enlargement. Advocates claim that their projects to build large orbital infrastructures, colonize celestial bodies, and alter asteroidal orbits can solve global energy and resource problems and ensure humanity’s survival from major Earth disasters. But the actual and prospective consequences of their projects are far darker then recognized. Space activities have increased the probability of nuclear war.

Abstract:
This chapter assesses the different kinds of police trades that emerged during the nineteenth century, looking at patrolmen and detectives. The new police institutions were permanent, disciplined bodies, but they continued to do the kind of things that had been done by various others, such as watches and constables, or their equivalents. They maintained order on the streets and the highways and byways; and order meant relative tidiness and no obstructions as well as breaking up fights. They arrested offenders, and, in some places, they were responsible for fighting fires. Specialist units began to take on specialist tasks. The detection of offenders, for example, had long been a role for those engaged in the wider role of policing, but detective bureaux became significant, if relatively small, branches of many police institutions, especially in the big cities. The new police, however, could not be everywhere and cover every policing problem. In some instances, the local population continued to act on its own, sometimes with the knowledge and agreement, even the participation, of the police, and sometimes without. The chapter then examines popular policing, as well as representations of the police in fiction.

Abstract:
Several years ago, my son and I moved into an apartment on the northern fringe of Graz, the capital of Styria, Austria. One day I decided to take a walk in a nearby forest through which a small stream, the Gabriachbach, flows. As I walked along the stream, I noticed in the water coloured glass shards as well as many nicely cut stone blocks. I became increasingly more curious and started to search the stream bed systematically. Picking up more and more artefacts, my collection grew at a great speed and soon the pockets of my trousers and the plastic shopping bag that I happened to have on me started to burst. Among other items, I found a water container, a broken lantern, several small glass bottles, and the fragment of a human long bone. As I gradually moved upstream, I found more worked stones in association with the remains of an iron fence. At that moment the realization dawned upon me that I was standing in the midst of the cleared out and dumped remains from a cemetery. Inquiring about the provenance of the remains, I was told by a friend of mine that they derive from a nearby graveyard, most likely of St Veit, and date to the first half of the twentieth century; he found a gravestone with the inscription ‘1943’. The dumping probably took place at the end of the 1970s since at that time the stream channel had been reconstructed, apparently with stones and other materials deriving from the cemetery. To find myself amidst discarded cemetery remains did not particularly shock me at the time. I assume it is my cultural disposition as an Austrian—we have a reputation for concerning ourselves with death quite happily—not worrying about such types of confrontations with the inevitability of death. I remember feeling a bit sad about all the dead people, their grave stones, flower vases, candle holders, and all the other belongings. My thoughts also went to those who had cared for the graves and who were also long gone. What really stuck in my mind though, is that overwhelming feeling of the futility of any material accomplishment by the dead as well as the lack of remembrance for them.

Abstract:
Trace elements migrate among different environment bodies with the natural geochemical reactions, and impacted by human industrial, agricultural, and civil activities. High load of trace elements in water, river and lake sediment, soil and air particle lead to potential to health of human being and ecological system. To control the impact on environment, source apportionment is a meaningful, and also a challenging task. Traditional methods to make source apportionment are usually based on geochemical techniques, or univariate analysis techniques. In recently years, the methods of multivariate analysis, and the related concepts data mining, machine learning, big data, are developing fast, which provide a novel route that combing the geochemical and data mining techniques together. These methods have been proved successful to deal with the source apportionment issue. In this chapter, the data mining methods used on this topic and implementations in recent years are reviewed. The basic method includes principal component analysis, factor analysis, clustering analysis, positive matrix fractionation, decision tree, Bayesian network, artificial neural network, etc. Source apportionment of trace elements in surface water, ground water, river and lake sediment, soil, air particles, dust are discussed.

Abstract:
The earth's magnetic fields are carriers of biologically relevant information that connects all living systems. The electromagnetic coupling of the human brain, cardiovascular and nervous systems, and geomagnetic frequencies supports the hypothesis that the mediated reality of electromagnetic bandwidths can be correlated with bio-energetic and geomagnetic frequencies. Understood as bio-energetic functions (Thinking, Feeling, Sensing, &amp; Intuiting), the media-sphere becomes measurable according to principles of coherency (measured as heart-rate variability, HRV) and principles of Jungian dream analysis (compensation and dramatic structure). It has been demonstrated that the rhythmic patterns in beat-to-beat heart rate variability reflect emotional functions, permeate every bodily cell, and play a central role in the generation and transmission of system-wide information via the electromagnetic field. So, the “media dream” becomes susceptible to psychological analysis leading to a better understanding of unconscious cognitive archetypal patterns of contextual collectives.

Abstract:
In the year 1600, the the man about to become physician to Queen Elizabeth I of England published a long treatise summarizing his two decades of experimentation on magnetism. After disposing of such issues as whether garlic causes magnets to “lose their virtue” William Gilbert recounted his observations upon moving a compass over the surface of a permanent magnet that had been specially fashioned in the form of a sphere (Gilbert, 1893, 1958). The similarity between the compass readings on the surface of his magnet and those recorded in mariners’ charts led Gilbert to conclude that his magnet was a terrella, a little earth, and that our big earth is (among other things) a giant magnet. Gilbert’s little earth organized the pattern of compass readings not only on its surface but also in the space surrounding it. From this, he boldly asserted that the big earth’s magnetic influence continues far into empty space, where no mariner of his day could ever go. The profundity of this remark was not lost on Gilbert’s younger contemporary, Johannes Kepler, who found in it an explanation of the earth’s annual motion around the sun. Kepler reasoned more or less as follows (in modern language): Since the earth and the sun are both celestial bodies, they both should rotate, and they both should have magnetic fields surrounding them in space. Their two rotating fields interact somehow, somewhere, in the space between them, communicating the sun’s rotational motion to the earth and pushing the earth around its orbit. In this curious way, Kepler might have been the first to perceive that the sun acts upon terrestrial magnetism. He was not the last. In 1580, Kepler’s teacher, Michael Maestlin, had recorded an observation of a distinct region of oscillating luminosity in the northern sky, an aurora. The aurora had been a topic of scientific interest since Graeco-Roman antiquity [of particular importance was Aristotle’s (384-322 B.C.) discussion of it in his Meteorology], but it had become an object of superstition in the European Middle Ages, and scientific interest in it only began to re-emerge in the second half of the 16th century (Link, 1957).

In this study, we designed and fabricated a new 3D direct current electric field (DCEF) stimulation bio-reactor and investigated the effectiveness on the axonal outgrowth enhancement. We searched an optimum structure using the finite element (FE) analyses to obtain a uniform DCEF in the culture region. A measurement result of DCEF strength showed an agreement with FE results.

Abstract:
Implementation of lightweight low-ductility materials such as aluminum alloys, magnesium alloys and composite materials has become urgently needed for automotive manufacturers to improve the competitiveness of their products. However, the hybrid use of these materials poses big challenges to joining processes. Self-piercing riveting (SPR) is currently the most popular technique for joining dissimilar materials and has been widely used in joining all-aluminum and multi-material vehicle bodies. However, in riveting magnesium alloys, cracks always occur for its low ductility. In this paper, a hyb

Abstract:
The difficult lives of workers in a manufacturing industry can be improved by the use of a simple ‘Hovercraft’. This vehicle runs on air from the pressure lines in any industry. Since there is zero resistance between the smooth surface and the craft, the effort to move very heavy bodies is reduced significantly. The craft with a specially designed skirting shape will allow it to lift the load placed on it with ease. There would be eddy formation and stability would need to be taken into account. Hovercraft has been designed before but its application in industries is of the level of innovation

Abstract:
Application of surface roughness to rotating mechanical bodies will result into performance degradation. In Aviation Industry, one of the most affecting causes for performance or efficiency degradation of gas turbine engine is the blade surface roughness. The aerosols which are very small particles in the atmosphere having diameters in the microns, impinges to the compressor blade inside the aircraft engine at higher altitudes. The aerosols damages surfaces of the compressor blades. Despite of having small dimensions, due to higher velocity of the aircraft, aerosol’s impinging creates roughene

Abstract:
The unsteady flow field around a moving airfoil has attracted significant attention in bio-hydrodynamics, micro-air-vehicles and micro flight robots. Recently, a number of studies have been performed on the flow field around airfoils with unsteady motion in low Reynolds number regions using both experiment and numerical analysis. On the other hand, it is well known that insects and aquatic animals fly or swim by skillfully controlling their wings or fins, which deform elastically, and vortices are generated around their bodies. The flow around an elastic body is treated as a coupled problem be

Abstract:
In Car Body Assembly Shops, Body in White (BIW), non-rigid sheet metal panels are assembled into car bodies. Depending upon the achieved degree of robustness in part and tool design, the produced items tend to deviate more or less from their nominal specifications. Catching eventual non-robust solutions early on in the development phases is important to minimize time-consuming, expensive testing and trimming activities late in the development- and industrialization phases. To meet these demands, there is today an increased use of virtual forming and assembly tools within the automotive industr

The objective of this paper is to establish a concise structural model of the human musculoskeletal system (HMS) that can be applied to an exercise therapy that treats malfunctions or distortions of the human body. There exist a number of traditional exercise therapy methods in Japan and China, but any systematic approaches for learning, coaching or training are not found to the best of the author’s knowledge. Among such approaches, we deal with an exercise therapy called Somatic Balance Restoring Therapy (SBRT) in which a patient executes a series of non-invasive and painless motions in face-

Of late, there is a growing need for quality engineers who have the ability to solve complex engineering problems with reasonable knowledge of ethics and economics. This has led many universities to pursue accreditation by professional engineering bodies. While the accreditation process installs a standardized system of quality teaching, it is important that the engineering entrants have a degree of understanding that allows implementation of quality teaching methods. This study looks at the performance of first year engineering students in a bid to identify major issues that students face in
