Wielding Social Media in the Cyber-Arena: Globalism, Nationalism, and Civic Education

Information technology is a tool, and its effects on global citizenship education (GCED) depend on who uses the technology, how it is employed, and for what purpose. In theory, technology use could provide significant benefits toward achievement of GCED goals. Globalization has demanded an educational response — to prepare the young for productive engagement with the emerging global community. Technology could play a positive role in effective GCED. But globalization has come at a cost; it has produced winners and losers. Among the losers are those economically displaced as manufacturing jobs move elsewhere; they are resentful of foreigner and fearful of an uncertain future. For them, global citizenship is anathema. They are susceptible to manipulation by malign forces eager to exploit any perceived rifts in the post-war world order. For them, technology is a weapon, as easily aimed at the aspirations of GCED as another apparent enemy.             Identifying how technology can be employed positively in GCED is important, but not enough. Young people must also understand the conflict between globalization and alt-right nationalist populism, much of it carried out in the cyber-arena of the Internet and social media. New technologies have armed adversaries with tools to manipulate opinion and foment disorder. how technology is employed to undermine global citizenship education, as well as the democracies of the West. This they can witness in the gladiatorial combat between globalization and nationalist populism —between democracy and authoritarianism — in the cyber-arena. This article explores how technology is a double-edged sword – a tool for good and a tool for mischief. It draws from current research and news reporting on methods and effects of online manipulation. The article concludes by describing international efforts to defend against social media assaults on democracy and by identifying the new knowledge and skills citizens must acquire for positive civic engagement in the global cyber-arena. &nbsp

The Relationship of Organizational Justice and Interpersonal Attraction in Survivors’ Acceptance of Co-Worker Terminations

The main purpose of this study was to examine the relationship of organizational justice and interpersonal attraction in survivors’ acceptance of co-worker terminations. Four scenarios were tested manipulating high and low levels of the two independent variables (organizational justice and interpersonal attraction) and their effects on the dependent variable (level of acceptance of coworker terminations). Findings indicate justice during the termination process is more important than how much the coworker was liked on the survivors’ acceptance of coworker terminations. The practical implication is that organizations must be careful to insure that terminations are done in a just manner in order to engender the acceptance of the surviving workforce

Affective organizational commitment and organizational citizenship behavior: examining the relationship through the lens of equity sensitivity

The main purpose of this study was to test the relationship between affective organizational commitment (AOC), organizational citizenship behavior (OCB), and equity sensitivity, which heretofore has not been examined. Results revealed an interaction between AOC and equity sensitivity such that persons with an entitled orientation exhibited higher levels of OCB as their degree of AOC increased. Individuals with an entitled orientation and lower levels of AOC exhibited the lowest levels of OCB. This research suggests that organizations should focus on improving the level of AOC in order to increase the citizenship behavior of their entitled members. The moderating effect of equity sensitivity may help to explain why the relationship between AOC and OCB has been characterized as modest or weak in previous research studies

What have we already learned from the CMB?

The COBE satellite, and the DMR experiment in particular, was extraordinarily successful. However, the DMR results were announced about 7 years ago, during which time a great deal more has been learned about anisotropies in the Cosmic Microwave Background (CMB). The CMB experiments currently being designed and built, including long-duration balloons, interferometers, and two space missions, promise to address several fundamental cosmological issues. We present our evaluation of what we already know, what we are beginning to learn now, and what the future may bring.Comment: 20 pages, 3 figures. Changes to match version accepted by PAS

Spacelab Flight Operations

This paper will cover the primary activities involved in conducting Spacelab flight operations. Spacelab flight operations are characterized by a unique partnership between the operators of the Space Transportation System (STS) and the Mission Management organization. This partnership involves both the activities of the flight control personnel and the flight crew and must exist as an integrated team in order to be able to successfully complete a Spacelab flight. This paper will discuss an overview of how this partnership functions from the initial planning phase though the actual flight conduct. The responsibilities and functions of the flight crew members will be discussed as well as the make up of the flight control team. A typical flight scenario describing the basic operation of the Spacelab will be covered. A description of the Mission Control Center (MCC) and Payload Operations Control Center-(POCC) capabilities wiH be given

TC-99m HMPAO Brain Blood Flow Imaging in the Dementias with Histopathologic Correlation in 73 Patients

The purpose of this study is to determine the value of Tc-99m HMPAO SPECT in the diagnosis of the dementias. Tc-99m HMPAO was used with a 3-camera scanner to produce 5 sets of sectional images of the brain. Images were further processed using Statistical Parametric Mapping. Diagnosis was made by a physician blinded to the clinical diagnosis. Results in 73 subjects were compared with a neuropathologic study of the brain at autopsy. Data were analyzed for sensitivity, specificity, positive and negative predictive values and accuracy. These results are compared with several other studies performed with Tc-99m HMPAO SPECT with histopathologic correlation. This procedure is widely available and relatively inexpensive and may be of value in patients with dementias and problematic diagnoses. Further, a degree of differential diagnosis between Alzheimer's and Frontotemporal diseases may be effected. The study was approved by our Institutional Review Board

Conformational flexibility revealed by the crystal structure of a crenarchaeal RadA

Homologous recombinational repair is an essential mechanism for repair of double-strand breaks in DNA. Recombinases of the RecA-fold family play a crucial role in this process, forming filaments that utilize ATP to mediate their interactions with single- and double-stranded DNA. The recombinase molecules present in the archaea (RadA) and eukaryota (Rad51) are more closely related to each other than to their bacterial counterpart (RecA) and, as a result, RadA makes a suitable model for the eukaryotic system. The crystal structure of Sulfolobus solfataricus RadA has been solved to a resolution of 3.2 Å in the absence of nucleotide analogues or DNA, revealing a narrow filamentous assembly with three molecules per helical turn. As observed in other RecA-family recombinases, each RadA molecule in the filament is linked to its neighbour via interactions of a short β-strand with the neighbouring ATPase domain. However, despite apparent flexibility between domains, comparison with other structures indicates conservation of a number of key interactions that introduce rigidity to the system, allowing allosteric control of the filament by interaction with ATP. Additional analysis reveals that the interaction specificity of the five human Rad51 paralogues can be predicted using a simple model based on the RadA structure

The Born and Lens-Lens Corrections to Weak Gravitational Lensing Angular Power Spectra

We revisit the estimation of higher order corrections to the angular power spectra of weak gravitational lensing. Extending a previous calculation of Cooray and Hu, we find two additional terms to the fourth order in potential perturbations of large-scale structure corresponding to corrections associated with the Born approximation and the neglect of line-of-sight coupling of two foreground lenses in the standard first order result. These terms alter the convergence ($\kappa\kappa$), the lensing shear E-mode ($\epsilon\epsilon$), and their cross-correlation ($\kappa\epsilon$) power spectra on large angular scales, but leave the power spectra of the lensing shear B-mode ($\beta\beta$) and rotational ($\omega\omega$) component unchanged as compared to previous estimates. The new terms complete the calculation of corrections to weak lensing angular power spectra associated with both the Born approximation and the lens-lens coupling to an order in which the contributions are most significant. Taking these features together, we find that these corrections are unimportant for any weak lensing survey, including for a full sky survey limited by cosmic variance.Comment: Added references, minor changes to text. 9 pages, 2 figure
