Fundamental Rights in the European Community Legal Order
The role of the courts in the protection of human rights in any legal system is a constitutionally sensitive one. The observance and protection of such rights articulate with many aspects of the exercise of governmental and legislative power. The value nature of human rights accentuates these sensibilities. Some have viewed sovereign law as an essential ingredient in the make-up of national identity, a perception which tends to confirm a presumption that legal systems, while responsive to new pressures, are nonetheless holistic, coherent, and state-bound. National law is a rampart against outside corruption of the national ethos. Inevitably all of this poses particular challenges for a supranational court with jurisdiction to pass judgment on human rights compliance, directly or indirectly, by states that are justly proud of their own legal democratic traditions. The exercise by the European Court of Justice (âCourt of Justiceâ or âCourtâ) of jurisdiction to protect the individual from breaches of their fundamental rights is a constitutional role which trammels not only the exercise of political power by the institutions of the European Community (the âCommunityâ) but indirectly (and often directly) the use of governmental and legislative power at a national level. This constitutional role, exercised in the context of the doctrines of primacy and direct effect, challenges the ideology of a state\u27s legal autonomy and the associated sense of self-determination. Not surprisingly, the Court of Justice at the early stages showed a marked reluctance to be drawn into this area
Ten Micron Photometry of 25 Stars from B8 To M7
A photometer employing a liquid hydrogen-cooled mercury-doped germanium photoconductor whose spectral response is limited to the 8 - 14 ” region by a low pass interference filter and a BaF_2 window coupled with the
cell's threshold wavelength has been placed at the east arm Cassegrain focus of the 200 inch Hale telescope.
Twenty-five stars have been measured. The earliest star for which two measurements have been obtained is the B8Ia star ÎČ Orionis. The latest star is the M7e star X Cygni. The brightest star, L37 X 10^(-14) watts/cm^2, is α Orionis. The carbon star DS Peg was also measured. In a two-color diagram formed with B and V there is an intrinsic increase
in dispersion going to later type stars and a systematic trend away from the blackbody relation. The ratios of the stellar fluxes to those expected from blackbodies at the published stellar effective-temperatures and angular diameters are not far from one. A systematic trend exhibited
may not be real because of the assumptions involved in inteferometric diameter determinations. DS Peg does not appear overly peculiar in the two-color plots, but X,Cygni falls on the opposite side of the blackbody curve ("blue excess") compared with most of the late type stars.
The fluxes presented here have not been corrected for presently uncertain telescope transmission losses which may be important
Using digital pens to expedite the marking procedure
This is the Post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2010 Inderscience PublishersDigital pens have been introduced over the last six years and have demonstrated that they can be used effectively for collecting, processing and storing data. These properties make them ideal for use in education, particularly in the marking procedure of multiple-choice questions (MCQ). In this report, we present a system that was designed to expedite the marking procedure of MCQ, for use at any educational level. The main element of the system is a digital pen, i.e. given to the students prior to the examination. On return of the pen, the system immediately recognises the students' answers and produces their results. In this specific research, four groups of students were studied and a variety of data were collected, concerning issues, such as accuracy, time gained by the use of the system and the impressions of the students. The pedagogic value of the use of the system is also presented
Analysis of a Model Biological Switch
A model mechanism proposed by Murray [Phil. Traps. Roy. Soc. London B, 295 (1981), pp. 473â496] for generating wing patterns and eyespots on butterflies and moths is based on a morphogen (S) activated biological switch for a gene product (g). We analyse one of the resulting partial differential equation systems, namely S_t = DÎS - kS, g_t = k_tS + αg (g-k_2) (g_c-g ), where D,k,k_1 ,k_2 ,g_c > k_2 and α are positive constants. We determine analytically the size of the spatial domain where g â g_c as t â â after an influx of S at the origin. This gives the size of the eyespot in terms of the mechanism parameters. The analytical problem is a nontrivial singular perturbation expansion which we discuss in detail
Coupling convectively driven atmospheric circulation to surface rotation: Evidence for active methane weather in the observed spin rate drift of Titan
A large drift in the rotation rate of Titan observed by Cassini provided the
first evidence of a subsurface ocean isolating the massive core from the icy
crust. Seasonal exchange of angular momentum between the surface and atmosphere
accounts for the magnitude of the effect, but observations lag the expected
signal by a few years. We argue that this time lag is due to the presence of an
active methane weather cycle in the atmosphere. An analytic model of the
seasonal cycle of atmospheric angular momentum is developed and compared with
time-dependent simulations of Titan's atmosphere with and without methane
thermodynamics. The disappearance of clouds at the summer pole suggests the
drift rate has already switched direction, signaling the change in season from
solstice to equinox.Comment: 6 pages, 4 figures, published in Ap
