Knowing the bottleneck is one of the keys to improving a production system. The active period method is one approach to detect shifting bottlenecks that most other bottleneck detection methods have problems with. Yet, like many other methods, these detections are limited to detecting the past and present bottlenecks. In this paper, we combined the active period method with the buffer Preprint o...

Evaluates the the act frequency approach (AFA), noting that retrospective self-reports rather than behavioral acts are studied; act context and meaning are not considered; the AFA self-report inventories are incompletely developed and are psychometrically unsound; the AFA claim of absolute measurement of dispositions is insupportable; many of the self-report act statements used are technically ...

Background. Data regarding depression and resilience among adolescents is still lacking. Objective. To assess depressive symptoms and resilience among pregnant adolescents. Method. Depressive symptoms and resilience were assessed using two validated inventories, the 10-item Center for Epidemiologic Studies Short Depression Scale (CESD-10) and the 14-item Wagnild and Young Resilience Scale (RS),...

The existence of 'Learning Styles' is a common 'neuromyth', and their use in all forms of education has been thoroughly and repeatedly discredited in the research literature. However, anecdotal evidence suggests that their use remains widespread. This perspective article is an attempt to understand if and why the myth of Learning Styles persists. I have done this by analyzing the current resear...

Knowledge of typical phonological development in bilingual children is limited. Bilingual children are often compared to their monolingual peers to determine typical from disordered development; however, it is not known if this comparison is an appropriate one. Although there have been some studies examining accuracy of production in bilinguals (GildersleeveNeumann, Kester, Davis, & Peña, 2008;...

This paper considers a two-period model in which two labour-managed firms can use inventory investment as a strategic device. In the first period, each firm simultaneously and independently chooses how much it sells in the current market and the level of inventory it holds for the second-period market. The paper shows the reaction curves in the model with inventories. The paper finds that inven...

A model with two types of consumers, shoppers and captives, is constructed that leads to an equilibrium price dispersion. Shoppers may hold inventories of the good; the level of consumer inventories leads to state-dependent price dispersions. It is shown that prices and quantities display negative serial correlation. The model is tested using grocery store data, which display the predicted corr...

I introduce inside money and serially correlated supply shocks to the Uncertain and Sequential Trading (UST) monetary model and test its implications using a vector auto regression impulse response analysis on post-war US data. I find that (a) The importance of money in predicting output is substantially reduced once the stock of inventories is added to the VAR system and (b) Shocks to inventor...

Prior work has investigated time and inventory-level dependent pricing of limited inventories with finite selling horizons. We consider a third dimension in addition to time and inventory level that the firms can use in setting their prices: the information that the firm has at the individual customer level. An arriving customer provides a signal to the firm, which is an imperfect indicator of ...
