Economic order/production quantity (EOQ/EPQ) models have generally been presented for manufacturing products. Incorporating some important features of a specific category of products, different EOQ/EPQ models have been proposed in literature. This study proposes a new class of inventory models, i.e. a model for a specific type of inventory items: growing items. Poultry and livestock are good ex...

Introduction: The aim of this work is to assess the role of the breast cancer (BC) specific Patient Concerns Inventory (PCI) in the identification of body image concerns in breast cancer patients. Materials and methods: A cross-sectional survey, using the BC specific PCI with an established breast cancer HRQOL measure (EORTC C30 with BR23). Results: Survey responses were obtained from 80% (200/...

ion is the process of highlighting some of the aspects of a thing in order to grasp its characteristics. It is somehow a process of generalization. Abstracting an observable thing leads to a general representation of this reality, which is often called a concept. Data items are unprocessed and uninterpreted symbols. They are elementary descriptions of measurable properties. Information is what ...

PURPOSE To develop a nystagmus-specific quality-of-life (QOL) questionnaire derived from patient concerns based on eudaimonic aspects of well-being. DESIGN Cross-sectional study. PARTICIPANTS A total of 206 participants with nystagmus for factor analysis phase and an additional 42 participants with nystagmus for construct validity phase. METHODS Questionnaire items were written on the bas...

Although significant intraindividual differences in self-reported diurnal preference, as measured by validated questionnaires, exist, the relative contribution of exogenous and endogenous factors to self-reported diurnal preference largely remains to be investigated. The present study examined which items from the Horne-Östberg (HÖ) questionnaire of diurnal preference were better at predicting ...

Visual search is often guided by top-down attentional templates that specify target-defining features. But search can also occur at the level of object categories. We measured the N2pc component, a marker of attentional target selection, in two visual search experiments where targets were defined either categorically (e.g., any letter) or at the item level (e.g., the letter C) by a prime stimul...

In the current study, we fit confirmatory bi-factor models to the items of the Autism Spectrum Quotient (AQ) and Autism Spectrum Quotient Short Form (AQ-S) in order to assess the extents to which the items of each reflect general versus specific factors. The models were fit in a combined sample of individuals with and without a clinical diagnosis of autism spectrum disorders. Results indicated ...

Abstract We investigated the nature of sensory integration deficits in postural control of young adults with ASD. Postural control was assessed in a fixed environment, and in three environments in which sensory information about body sway from visual, proprioceptive or both channels w...

Merging related RSS news (coming from one or different sources) is beneficial for end-users with different backgrounds (journalists, economists, etc.), particularly those accessing similar information. In this paper, we provide a practical approach to both: measure the relatedness, and identify relationships between RSS elements. Our approach is based on the concepts of semantic neighborhood an...

Frequent itemsets and association rules are generally accepted concepts in analyzing item-based databases. The Apriori-framework was developed for analyzing categorical data. However, many data include numerical values. Therefore, most existing techniques transform numerical values to categorical values. The transformation is done such that the rules are optimal with respect to support or confi...
