Inquiring of ‘Beelzebub’

This study juxtaposes the concerns of Catholios Timothy I (r. 780–823), leader of the Church of the East, with those of al-Jāḥiẓ (about 776–868/9), a popular Muslim writer, regarding the dangers for each community when Christians appear as plaintiffs or defendants in Islamic courts. Timothy’s Canons attempt to obviate some of the reasons Christians might voluntarily appeal to Islamic courts rather than resolving disputes within the church, and Canon 12 in particular uses a biblical turn of language to condemn this practice. By contrast, cases involving a Muslim disputant had to be tried in Islamic courts, and al-Jāḥiẓ argues that judges who mete out sentences favorable to Christians in such cases jeopardize the rightful social order of Muslims in regard to ahl al-dhimma (protected people)

Takeover Risk and the Market for Corporate Control: The Experience of British Firms in the 1970s and 1980s

This paper investigates the determinants of takeovers in a large sample of UK quoted companies. We focus on the channels through which the market for corporate control monitors company performance and discretionary managerial behaviour. Our results indicate that the market for corporate control disciplines poorly performing companies, and that this effect is quantitatively important: a one standard deviation increase in profitability is associated with a fall in the conditional probability of takeover of over 20%. However, we find no evidence that firms without apparent profitable investment opportunities are more likely to be taken over if managers increase investment or reduce dividends, contrary to the predictions of the free cash-flow theory of takovers

Is Attack the Best form of Defence? A Competing Risks Analysis of Acquisition Activity in the UK

The primary purpose of this paper is to investigate whether companies can use acquisition as a strategy to reduce their probability of takeover. A subsidiary issue is whether such a strategy has any impact on their subsequent probability of bankruptcy. The determinants of making an acquisition, being taken over, and bankruptcy are modelled within a competing risks framework using two large samples of UK manufacturing companies. Our results indicate that, ceteris paribus, companies which make acquisitions can significantly reduce their conditional probability of being taken over, largely through the impact that acquisition has on corporate size. In this sense, attack, through acquisition, is the best form of defence, against takeover

Proprioceptive perception of phase variability

Previous work has established that judgments of relative phase variability of 2 visually presented oscillators covary with mean relative phase. Ninety degrees is judged to be more variable than 0° or 180°, independently of the actual level of phase variability. Judged levels of variability also increase at 180°. This pattern of judgments matches the pattern of movement coordination results. Here, participants judged the phase variability of their own finger movements, which they generated by actively tracking a manipulandum moving at 0°, 90°, or 180°, and with 1 of 4 levels of Phase Variability. Judgments covaried as an inverted U-shaped function of mean relative phase. With an increase in frequency, 180° was judged more variable whereas 0° was not. Higher frequency also reduced discrimination of the levels of Phase Variability. This matching of the proprioceptive and visual results, and of both to movement results, supports the hypothesized role of online perception in the coupling of limb movements. Differences in the 2 cases are discussed as due primarily to the different sensitivities of the systems to the information

Dissociation of Action and Object Naming: Evidence From Cortical Stimulation Mapping

This cortical stimulation mapping study investigates the neural representation of action and object naming. Data from 13 neurosurgical subjects undergoing awake cortical mapping is presented. Our findings indicate clear evidence of differential disruption of noun and verb naming in the context of this naming task. At the individual level, evidence was found for punctuate regions of perisylvian cortex subserving noun and verb function. Across subjects, however, the location of these sites varied. This finding may help explain discrepancies between lesion and functional imaging studies of noun and verb naming. In addition, an alternative coding of these data served to highlight the grammatical class vulnerability of the target response. The use of this coding scheme implicates a role for the supramarginal gyrus in verb-naming behavior. These data are discussed with respect to a functional-anatomical pathway underlying verb naming

Analysis and Assessment of the Reimbursement Rates and Mechanisms for Kentucky’s Publicly Funded Ferries

The Kentucky Transportation Cabinet (KYTC) reimburses publicly operated ferries, including when they cease operations due to severe weather or unforeseen events. Reimbursement procedures are not codified in law and are largely based on historical practice. To determine how the Cabinet should handle reimbursement, funding, oversight of ferry services moving forward, the Kentucky Transportation Center (KTC) reviewed practices adopted by 10 other states and conducted a detailed analysis of Kentucky’s current approach. Of the states KTC examined, only Tennessee reimburses ferry operations for closures (at 50 percent of the normal hourly rate for a period up to 48 hours). Half of the states KTC examined make state funding available for ferry operations, others either devolve oversight to the local level or provide no funding assistance. In Kentucky, operating standards for ferry services are not consistent and no uniform method has been devised to calculate reimbursement rates. In light of these findings, KYTC should create detailed auditing guidelines to improve the consistency of ferry service financial statements; pursue funding sources it has not previously taken advantage of, and generate long-term forecasts of the state’s ferry operations. Lastly, the Cabinet should ask the General Assembly to revisit and modify several statutes pertaining to ferries which contain outdated language that has little relevance to the modern transportation system

The formation of atomic oxygen and hydrogen in atmospheric pressure plasmas containing humidity : picosecond two-photon absorption laser induced fluorescence and numerical simulations

Atmospheric pressure plasmas are effective sources for reactive species, making them applicable for industrial and biomedical applications. We quantify ground-state densities of key species, atomic oxygen (O) and hydrogen (H), produced from admixtures of water vapour (up to 0.5%) to the helium feed gas in a radio-frequency-driven plasma at atmospheric pressure. Absolute density measurements, using two-photon absorption laser induced fluorescence, require accurate effective excited state lifetimes. For atmospheric pressure plasmas, picosecond resolution is needed due to the rapid collisional de-excitation of excited states. These absolute O and H density measurements, at the nozzle of the plasma jet, are used to benchmark a plug-flow, 0D chemical kinetics model, for varying humidity content, to further investigate the main formation pathways of O and H. It is found that impurities can play a crucial role for the production of O at small molecular admixtures. Hence, for controllable reactive species production, purposely admixed molecules to the feed gas is recommended, as opposed to relying on ambient molecules. The controlled humidity content was also identified as an effective tailoring mechanism for the O/H ratio

Ultraviolet Imaging Polarimetry of the Large Magellanic Cloud. II. Models

Motivated by new sounding-rocket wide-field polarimetric images of the Large Magellanic Cloud, we have used a three-dimensional Monte Carlo radiation transfer code to investigate the escape of near-ultraviolet photons from young stellar associations embedded within a disk of dusty material (i.e. a galaxy). As photons propagate through the disk, they may be scattered or absorbed by dust. Scattered photons are polarized and tracked until they escape to be observed; absorbed photons heat the dust, which radiates isotropically in the far-infrared, where the galaxy is optically thin. The code produces four output images: near- UV and far-IR flux, and near-UV images in the linear Stokes parameters Q and U. From these images we construct simulated UV polarization maps of the LMC. We use these maps to place constraints on the star + dust geometry of the LMC and the optical properties of its dust grains. By tuning the model input parameters to produce maps that match the observed polarization maps, we derive information about the inclination of the LMC disk to the plane of the sky, and about the scattering phase function g. We compute a grid of models with i = 28 deg., 36 deg., and 45 deg., and g = 0.64, 0.70, 0.77, 0.83, and 0.90. The model which best reproduces the observed polarization maps has i = 36 +2/-5 degrees and g ~0.7. Because of the low signal-to-noise in the data, we cannot place firm constraints on the value of g. The highly inclined models do not match the observed centro-symmetric polarization patterns around bright OB associations, or the distribution of polarization values. Our models approximately reproduce the observed ultraviolet photopolarimetry of the western side of the LMC; however, the output images depend on many input parameters and are nonunique.Comment: Accepted to AJ. 20 pages, 7 figure
