early in the development of many animals, before transcription begins, any change in the pattern of protein synthesis is attributed to a change in the translational activity or stability of mrna in the egg and early embryo. as a result, translational control is critical for a variety of developmental decisions, including oocyte maturation and initiation of preimplantation development. in this s...
abstract this study aimed at investigating the effect of bilingual teaching of cognate words (persian-english) on iranian upper intermediate efl learners’ knowledge of lexical development. for this purpose,100 subjects participated in this study out of which 40 learners were selected for this study and they were assigned into two groups, control and experimental. cross-language cognates (wor...
Development is one of the most important concepts for countries, especially for developing countries in the Third World. Southeast Asian countries are among the countries that, as development-oriented states, could achieve an optimal and high development by adopting appropriate political-economic policies. Malaysia, especially from the time of the Prime Minister Mahatyr Muhammad, was able to ac...
State incentive granting for the purpose of firm retention or recruitment remains highly controversial and is often portrayed as antithetical to long-range economic development planning. This paper uses quasi-experimental methods to measure the impact of state-level economic development incentives on employment growth at the establishment level in North Carolina. Using North Carolina’s rich his...
Applications. The problem of computing f(g), under the restrictions deg f < n and g(0) = 0, is known as order-n power series composition. Here is the point: given power series u and v over R, with v(0) = 0, define f = u(z) mod z and g = v(x) mod x; then f(g) = u(v(x)) mod x. Power series composition is the bottleneck in reversion and iteration of power series. See Brent and Kung (1978) and Knut...
The paper empirically examines the relationship between trade openness and the level of corruption in Pakistan using annual time-series data for the period 1984 to 2007. The analysis shows that trade openness negatively affects corruption in Pakistan. The results are robust to controlling for other corruption determining variables and various model specifications. Sensitivity analysis shows tha...
the main objective of the current study is to investigate the impacts of environmental evolutionsat global scale on iran’s environmental planning. thereby, all political movements towards solving environmental issues in iran were accurately reviewed to find out the impressibility of the events by the global environmental evolutions. the findings indicated that iran has joined the conventions an...
Processes of social opinion formation might be dominated by a set of highly influential agents acting as ‘opinion leaders’. Here we explore whether such a perspective could shed light on the dynamics of a well known economic sentiment index. To this end, we hypothesize that the respondents of the survey under investigation form a core-periphery network, and we identify those agents that define ...
We introduce a class of stochastic volatility models (Xt)t≥0 for which the absolute moments of the increments exhibit anomalous scaling: E (|Xt+h −Xt|) scales as hq/2 for q < q∗, but as hA(q) with A(q) < q/2 for q > q∗, for some threshold q∗. This multi-scaling phenomenon is observed in time series of financial assets. If the dynamics of the volatility is given by a mean-reverting equation driv...
Grubbs test (extreme studentized deviate test, maximum normed residual test) is used in various fields to identify outliers in a data set, which are ranked in the order of x 1 ≤ x 2 ≤ x 3 ≤ ⋅ ⋅ ⋅ ≤ x n (i = 1, 2, 3, . . . , n). However, ranking of data eliminates the actual sequence of a data series, which is an important factor for determining outliers in some cases (e.g., time series). Thus i...
