The Art History Canon and the Art History Survey Course: Subverting the Western Narrative.
Art History enrollments at the college level are declining as students flock to STEM majors and perceive Art History as dated and of little use in today’s modern, scientific world. Yet Art History classes can teach valuable skills. When taught in a broad context, the objects art history studies engage critical thinking and can generate new forms of knowledge. However, the pedagogical structure and content of introductory art history survey course does not always offer students the creative leeway to make these connections. Instructors at the college level often retreat to the methods and content that have been a part of the discipline since its inception in the late 19thcentury; the professor as expert authority on the western canon of objects and the grand narrative of progressive development that accompanies them. As university students are becoming more ethnically and socially diverse, the objects covered in the survey continue to speak to a white, European audience that is no longer the only audience listening. While art history remains useful, its canon of objects has become problematic, and reinforces the othering of the non- western world.
This essay will first examine how the modern canon and art history’s pedagogical practices came to be by examining the history of the discipline, and the theories, methods and texts that developed alongside academic art history. It will then take a brief look at how modern philosophy, primarily the conceptual ideas of Deleuze and Guattari, can provide a new framework for examining how the teaching of art history can be globalized and taught in a more meaningful way
An Analysis of Ocular Counterrolling in Response to Body Positions in Three-Dimensional Space
Is J 133658.3-295105 a Radio Source at z >= 1.0 or at the Distance of M 83?
We present Gemini optical imaging and spectroscopy of the radio source J
133658.3-295105. This source has been suggested to be the core of an FR II
radio source with two detected lobes. J 133658.3-295105 and its lobes are
aligned with the optical nucleus of M 83 and with three other radio sources at
the M 83 bulge outer region. These radio sources are neither supernova remnants
nor H II regions. This curious configuration prompted us to try to determine
the distance to J 133658.3-295105. We detected H_alpha emission redshifted by ~
130 km s^-1 with respect to an M 83 H II region 2.5" east-southeast of the
radio source. We do not detect other redshifted emission lines of an optical
counterpart down to m_i = 22.2 +/- 0.8. Two different scenarios are proposed:
the radio source is at z >= 2.5, a much larger distance than the previously
proposed lower limit z >= 1.0, or the object was ejected by a gravitational
recoil event from the M 83 nucleus. This nucleus is undergoing a strong
dynamical evolution, judging from previous three-dimensional spectroscopy.Comment: 6 pages, 4 figure
Passive security threats and consequences in IEEE 802.11 wireless mesh networks
The Wireless Mesh Network (WMN) is ubiquitous emerging broadband wireless network. However, the open wireless medium, multi-hop multi-radio architecture and ad-hoc connectivity amongst end-users are such characteristics which increases the vulnerabilities of WMN towards many passive and active attacks. A secure network ensures the confidentiality, integrity and availability of wireless network. Integrity and availability is compromised by active attacks, while the confidentiality of end-users traffic is compromised by passive attacks. Passive attacks are silent in nature and do not harm the network traffic or normal network operations, therefore very difficult to detect. However, passive attacks lay down a foundation for later launching an active attack. In this article, we discuss the vulnerable features and possible passive threats in WMN along with current security mechanisms as well as future research directions. This article will serve as a baseline guide for the passive security threats and related issues in WMNs
Optical fluid and biomolecule transport with thermal fields
A long standing goal is the direct optical control of biomolecules and water for applications ranging from microfluidics over biomolecule detection to non-equilibrium biophysics. Thermal forces originating from optically applied, dynamic microscale temperature gradients have shown to possess great potential to reach this goal. It was demonstrated that laser heating by a few Kelvin can generate and guide water flow on the micrometre scale in bulk fluid, gel matrices or ice without requiring any lithographic structuring. Biomolecules on the other hand can be transported by thermal gradients, a mechanism termed thermophoresis, thermal diffusion or Soret effect. This molecule transport is the subject of current research, however it can be used to both characterize biomolecules and to record binding curves of important biological binding reactions, even in their native matrix of blood serum. Interestingly, thermophoresis can be easily combined with the optothermal fluid control. As a result, molecule traps can be created in a variety of geometries, enabling the trapping of small biomolecules, like for example very short DNA molecules. The combination with DNA replication from thermal convection allows us to approach molecular evolution with concurrent replication and selection processes inside a single chamber: replication is driven by thermal convection and selection by the concurrent accumulation of the DNA molecules. From the short but intense history of applying thermal fields to control fluid flow and biological molecules, we infer that many unexpected and highly synergistic effects and applications are likely to be explored in the future
