The paper focuses on some inferential elements in EFL learning Mbujimayi. More specifically, the study points out differences occurring English sound production of /t/, /dʒ/, /ʒ/, /ð/, /v/, and /θ/ by Ciluba speaking learners. After discussing findings obtained from observation questionnaire, it has been discovered that learners’ prior linguistic knowledge justifies errors they make this regard...

Rigidity in wages has long been thought to impede the functioning of labor markets. One recent strand of the research on wage flexibility in the United States and elsewhere has focused on the possibility of downward nominal wage rigidity and what implications such rigidity might have for the macroeconomy at low levels of inflation. The Great Recession of 2008-09, during which the unemployment r...

We present a manually constructed seed lexicon encoding the inferential profiles of French event selecting predicates across different uses. The inferential profile (Karttunen, 1971a) of a verb is designed to capture the inferences triggered by the use of this verb in context. It reflects the influence of the clause-embedding verb on the factuality of the event described by the embedded clause....

We use algebraic geometry to study matrix rigidity, and more generally, the complexity of computing a matrix-vector product, continuing a study initiated in [13, 11]. In particular, we (i) exhibit many non-obvious equations testing for (border) rigidity, (ii) compute degrees of varieties associated to rigidity, (iii) describe algebraic varieties associated to families of matrices that are expec...

We study rigidity properties of lattices in Isom(H) SOn,1(R), n ≥ 3, and of surface groups in Isom(H2) SL2(R) in the context of integrable measure equivalence. The results for lattices in Isom(H), n ≥ 3, are generalizations of Mostow rigidity; they include a cocycle version of strong rigidity and an integrable measure equivalence classification. Despite the lack of Mostow rigidity for n = 2 we ...

We study the properties of affine rigidity of a hypergraph and prove a variety of fundamental results. First, we show that affine rigidity is a generic property (i.e., depends only on the hypergraph, not the particular embedding). Then we prove that a graph is generically neighborhood affinely rigid in d-dimensional space if it is (d+1)-vertex-connected. We also show neighborhood affine rigidit...

The article shows the effect of torsional rigidity of beam elements onto spatial work of bridges, floorings and other plate-ribbed systems It is shown that, in determining the torsional rigidity using existing methods it is necessary to have spatial spiral cracks, but torsional rigidity when normal cracks is not researched. A method is described for determining the torsional rigidity of reinfor...
