Mire jó a nyelvmƱvelés?
Az iskolai anyanyelvtanĂtĂĄs termĂ©szetes rĂ©sze a nyelvmƱvelĂ©s. NyelvĂ©sz körökben azonban folyamatos vitĂĄk kapcsolĂłdnak hozzĂĄ, s vannak, akik megkĂ©rdĆjelezik a lĂ©tjogosultsĂĄgĂĄt is. Az anyanyelvpedagĂłgiĂĄval kapcsolatos szĂĄmos gond között valĂłszĂnƱleg nem ez a legĂ©getĆbb, de a vita tĂŒkrĂ©ben mĂ©gis megkerĂŒlhetetlen a kĂ©rdĂ©s: kell-e egyĂĄltalĂĄn az iskolĂĄban nyelvmƱvelĂ©ssel foglalkoznunk vagy, mint egyesek vĂ©lik, ez egyenesen ĂĄrtalmas tevĂ©kenysĂ©g. A vĂĄlasz keresĂ©sĂ©hez szeretnĂ©k hozzĂĄjĂĄrulni ebben a tanulmĂĄnyban, amely a kĂ©t tĂĄbor szövegeinek mögöttes megközelĂtĂ©seit igyekszik feltĂĄrni
Ăj episztemolĂłgiĂĄk kihĂvĂĄsa a nevelĂ©studomĂĄnyban
A magyar nevelĂ©studomĂĄnyban az utĂłbbi idĆben elĆtĂ©rbe kerĂŒltek a kutatĂĄsmĂłdszertanhoz kapcsolĂłdĂł problĂ©mafelvetĂ©sek, ritkĂĄbban esik azonban szĂł a mĂ©lyebben rejlĆ tudomĂĄnyelmĂ©leti alapokrĂłl Ă©s alapkĂ©rdĂ©sekrĆl. Ezzel ellentĂ©tben a kĂŒlföldi (pĂ©ldĂĄul angolszĂĄsz) pedagĂłgiĂĄban igen nagy irodalma van az episztemolĂłgiai jellegƱ kĂ©rdĂ©seknek, vitĂĄknak. A tĂĄrsadalomtudomĂĄnyokban az utĂłbbi Ă©vtizedekben ismĂ©t komoly kĂ©rdĂ©ssĂ© vĂĄlt, hogy mit Ă©rtĂŒnk tudomĂĄnyon Ă©s tudomĂĄnyossĂĄgon. SokfĂ©le Ășj hang jelent meg, s ezzel összefĂŒggĂ©sben több Ășj episztemolĂłgia tƱnt fel Ă©s követel helyet magĂĄnak a pedagĂłgiai kutatĂĄsok vilĂĄgĂĄban is, mint pĂ©ldĂĄul a posztstrukturalizmus vagy az Ășjmarxizmus. Ezek az elmĂ©letek szĂĄmos kihĂvĂĄst hoznak a nevelĂ©studomĂĄny szĂĄmĂĄra

An Observational Evidence for the Difference Between the Short and Long Gamma-Ray Bursts
The intrinsic fluence and duration distributions of gamma-ray bursts are well represented by log-normal
distributions. This allows a bivariate log-normal distribution fit to be made to the BATSE short and long bursts
separately. A statistically significant difference between the long and short groups is found. We argue that the
effect is probably real. Applying the CramĂ©râs theorem these results lead to some predictions for models of long
and short bursts
Anisotropy of the sky distribution of gamma-ray bursts
The isotropy of gamma-ray bursts collected in current BATSE catalog is studied. It is shown that the quadrupole term being proportional to \sim sin 2b sin l is non-zero with a probability of 99.9%. The occurrence of this anisotropy term is then confirmed by the binomial test even with the probability of 99.97 %. Hence, the sky distribution of all known gamma-ray bursts is anisotropic. It is also argued that this anisotropy cannot be caused exclusively by instrumental effects due to the nonuniform sky exposure of BATSE instrument. Separating the GRBs into short and long subclasses, it is shown that the short ones are distributed anisotropically, but the long ones seem to be distributed still isotropically. The character of anisotropy suggests that the cosmological origin of short GRBs further holds, and there is no evidence for their Galactical origin
Isotropic and anisotropic pointing models
This paper describes an alternative approach for generating pointing models
for telescopes equipped with serial kinematics, esp. equatorial or alt-az
mounts. Our model construction does not exploit any assumption for the
underlying physical constraints of the mount, however, one can assign various
effects to the respective components of the equations. In order to recover the
pointing model parameters, classical linear least squares fitting procedures
can be applied. This parameterization also lacks any kind of parametric
singularity. We demonstrate the efficiency of this type of model on real
measurements with meter-class telescopes where the results provide a root mean
square accuracy of 1.5-2 arcseconds.Comment: Accepted for publication in Exp. Astro
