It has been often noted that classical models of belief do not accurately represent the limits of human doxastic capacity, at least if belief is understood in a sufficiently internal sense. This is equally true of models of belief revision (Hansson, 2003). Furthermore, Rott (2004) has recently raised doubts about several of the most important of Gärdenfors postulates relating to belief revision...

the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
Part I of this paper Rott has argued that doxastic states should be repre sented as revision functions that take sequences of sentences of arbitrary nite length as arguments and return belief sets that is sets of sentences closed under some background logic Cn as a result We have interpreted the well known rationality postulates for belief change given by Alchourr on G ardenfors and Makinson an...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
We provide a precise representation for, and a calculation of the length of, possible path independent determinateness hierarchies of Field’s construction in [4]. We further show in the hierarchies Fα of Fieldian truth sets, and Herzberger’s Hα revision sequence starting from any recursive hypothesis for F0 (or H0) that essentially each Hα (or Fα) carries within it the history of the whole prio...
First, we present a formal account of splitting a knowledge base into two parts, expanding our previous results motivated by avoiding the GG ardenfors triviality results for revision semantics for condition-als. Second, we propose a speciic revision function and show that this function is optimal in the sense, that after revision as few conditional consequences as possible are changed. Third, w...
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
