A random vector $\b{X} = (X_1,\cdots,X_n)$ is weakly associated if and only if for every pair of partitions $\b{X}_1 = (X_{\pi(1)},\cdots,X_{\pi(k)}), \b{X}_2 = (X_{\pi(k+1),\cdots,X_{\pi(n)})$ of $\b{X}, P(\b{X}_1 \in A, \b{X}_2 \in B) \geq P(\b{X}_1 \in A)\b{P}(\b{X}_2 \in B)$ whenever A and B are open upper sets and $\pi$ is a permutation of ${1,\cdots,n}$. In this paper, we develop notions of weak positive dependence, which are weaker than a positive version of negative association (weak association) but stronger than positive orthant dependence by arguments similar to those of Shaked. We also illustrate some concepts of a particular interest. Various properties and interrelationships are derived.

In this paper we provide a teaching learning method for logic in debate, in particular, in debate of engineers. First we criticize the concept of argument and the Toulmin model on argument used in education for debate. We next provide a general method for learning arguments needed in debate. Finally, we suggest the hypothetico-inferential method and the model for inference to the best choice as argument methods coming in useful in debate education for engineers.

This paper explores some possible interpretations of subject/object in child language, pointing out some potential problems in recent works within the minimalist framework and suggesting different views on it. Particularly, we will focus on how to identify and/or license objects, since most of the studies relevant to this issue have accounted for subjects only. Discussing the results of the studies on child language data, we will show that previous syntactic explanations on subjects, which have seemed quite attractive and refined, may not hold when accounting for objects and various aspects and properties of arguments in those child languages. In doing so, we will suggest and support a performance-based account, a discourse-based account, and a markedness account.

This paper considers a make-to-order inventory-production system in which customer orders are admitted only when the number of outstanding customer orders is below a value committed by the system. We deal with general distributions for the customer order Inter-arrival, production, and replenishment lead time processes. Monotonicities of the optimal average cost with respect to these distribution parameters are established using sample path coupling arguments. When distributions are given as an exponential one, we implement a sensitivity analysis on the optimal inventory policy and show that it has monotonicities with respect to system costs using dynamic programming.

This paper offers an alternative to the common probability generating function approach to the solution of steady state equations when a Markovian queue has a multivariate state space. Identifying states and substates and grouping them into vectors appropriately, we formulate a two - dimensional Markovian queue as a Markov chain. Solving the resulting matrix equations the transition point steady state probabilities (SSPs) are obtained. These are then converted into arbitrary time SSPs. The procedure uses only probabilistic arguments and thus avoids a large and cumbersome state space which often poses difficulties in the solution of steady state equations. For the purpose of numerical illustration of the approach we solve a Markovian queue with one server and two classes of customers.

The Hurwitz-type Euler zeta function is defined as a deformation of the Hurwitz zeta function: $${\zeta}_E(s,x)={\sum_{n=0}^{\infty}}{\frac{(-1)^n}{(n+x)^s}}$$. In this paper, by using the method of Fourier expansions, we shall evaluate several integrals with integrands involving Hurwitz-type Euler zeta functions ${\zeta}_E(s,x)$. Furthermore, the relations between the values of a class of the Hurwitz-type (or Lerch-type) Euler zeta functions at rational arguments have also been given.

We prove the existence and multiplicity of nontrivial solutions for a fourth order problem ${\Delta}^2u+c{\Delta}u={\alpha}u-{\beta}(u+1)^-$ in ${\Omega}$, ${\Delta}u=0$ and $u=0$ on ${\partial}{\Omega}$, where ${\lambda}_1{\leq}c{\leq}{\lambda}_2$ (where $({\lambda}_i)_{i{\geq}1}$ is the sequence of the eigenvalues of $-{\Delta}$ in$H_0^1({\Omega})$) and ${\Omega}$ is a bounded open set in $R^N$ with smooth boundary ${\partial}{\Omega}$. The results are proved by applying minimax arguments and linking theory.

In this study, I examined the current situation of the reading instruction policy and the entity of the arguments and criticism surrounding the reading instruction policy. In addition, on the basis of this research I analyzed the problems of the reading instruction policy. Moreover, I suggested for the desirable direction and alternative of the reading instruction policy and the reading instruction.

This paper call attention to the characteristics of apartment unit plans as to the outdoor adjacency methods. My arguments will attempt to investigate spatial composition and each room sizes of the unit plans. So far, very little has been done in this direction. I will limits myself to study 573 plans which have been designed from 1996 till 2003. What emerges from this analysis is that these samples divided 3 types derived from the outdoor adjacency methods. Type 1 limits itself to 39 square meters unit plans. Type 2 was distributed from 49 square meters to 200 square meters with the exception of 100-110 square meters. And, type 3 ranges from 59 to 160 square meters. Therefore, it could be profitable each room's environmental condition (daylight, ventilation and etc) and diverse apartment building types to design in extent 49-160 square meters.

Argument alternation in English sentences such as "load hay onto the truck" vs. "load the truck with are swarming in the garden" vs. "The garden swarms with bees" present an interesting dilemma for ling in several ways. Along with each kind of syntactic rearrangement of arguments goes a subtle but sig systematic change in the verb's meaning. This has been called as different terminology such as "D "Verbal diathesis", and most commonly as "Argument alternation". Dowty adopts tern Agent-subject(A-subject) form and Location-subject(L-subject) form in referring the two kinds of analyses as well as describes their different properties. In this paper. I basically follow assumption while surveying several 1inguists's analysis and show its theoretical adequacy.
