Objectives: Behavior rating scales have been developed to increase ecological validity in the measurement of executive functions. As the teachers have a lot of contact with the students in the school environment, behavioral rating scale teacher’s form can provide useful information. The purpose of this study was to investigate the reliability and validity of the behavioral rating inventor...

Our work solves the problem of inventory tracking in the retail industry using Hidden Markov Models. It has been observed that inventory records are extremely inaccurate in practice (cf. [1–4]). Reasons for this inaccuracy are item losses due to item theft, mishandling, etc. which are unaccounted. Even more important are the lost sales due to lack of items on the shelf, called stockout losses. ...

The validity of the Dutch adaptation of the Buss-Durkee Hostility Inventory was investigated. On the basis of the ratings of the staff of a residential treatment center for adolescents with conduct disorders, two contrast groups (high versus low aggression) were formed. In all, 67 male adolescents participated in the study. The subscales of the inventory clearly discriminated between the two gr...

OBJECTIVE Social withdrawal is described as the condition in which an individual experiences a desire to make social contact, but is unable to satisfy that desire. It is an important issue for patients with motor neurone disease who are likely to experience severe physical impairment. This study aims to reassess the psychometric and scaling properties of the MND Social Withdrawal Scale (MND-SWS...

This paper studies a perishable inventory model, which assumes that each perishable item has finite lifetime, and only one item is consumed each time. The lifetimes of perishable items are independent random variables with the general distribution and so are the consumption internal. Under this assumption, by using backward equations and limit distribution of Markov skeleton processes, this pap...

Expected inventory order crossovers occur if at the moment of ordering it is expected that orders will not arrive in the sequence they are ordered. Recent research has shown that (a) expected inventory order crossovers will be encountered more frequently in future, and that (b) use of a myopic order-up-to policy based on a stochastic dynamic programming approach leads to improved performance co...

Although antidepressant trials typically use weekly ratings to examine changes in symptoms over six to 12 weeks, antidepressant treatments may improve symptoms more quickly. Thus, rating scales must be adapted to capture changes over shorter intervals. We examined the use of the 17-item Hamilton Depression Rating Scale (HDRS) to evaluate more rapid changes. Data were examined from 58 patients w...

BACKGROUND Although several studies have been performed to evaluate the personality differences amongst smokers with different dependency levels, they do not use constant criteria for patients selection. The inconsistencies between some of these findings suggest the need for using solid criteria such as the modified Fagerstrom Tolerance Questionnaire (mFTQ) score to evaluate the relation betwee...
