The article deals with the problem of modeling the commodity flows management of a trading company under the conditions of uncertain demand and long supply. The Author presents an analysis of modifications of diversified inventory management system with random demand, for which one can find the optimal inventory control strategies, including those…

Studies attest that learning is facilitated if teaching strategies are in accordance with students learning styles, making learning process more effective and considerably improving students performances. In this context, one major research point--and a challenge--is to efficiently discover students' learning styles. But, the test and validation…

The incorporation of engaging and meaningful learning experiences is essential for the enhancement of critical thinking and the development of scientific literacy. The study engaged several groups of students in activities designed to elicit their understanding of a graphical representation of motion, and to determine the kinesthetic effect of…

The Teachers' Retirement System of the State of Illinois is one of the worst-funded public pensions in the nation. In 2013, it held enough assets to cover only 41 percent of its future obligations (Buck Consultants, 2014). This shortfall has led to several reforms, mostly involving benefit cuts that have undermined retirement income security for…

Over the past decade, states and districts have updated teacher evaluation systems in response to federal incentives, such as waivers to No Child Left Behind and grants from Race to the Top. The use of multiple measures, however, raises an important issue for policymakers and practitioners: to what extent should different measures of a teacher's…

The purpose of this science education study is to explore visual cognition and eye tracking during medication selection in the student nurse anesthetist (first year and second year students) and the expert nurse anesthetist. The first phase of this study consisted of the selection of a specific medication (target) from an array of medications via…

The integrity of a structural system depends on the strength of materials, shape of the individual member and the elements used to hold the members together. In most undergraduate civil engineering curricula, a structural steel and/or reinforced concrete design course is required. Usually, the main focus of these courses is on member selection…

The study presents the results of a pilot implementation of the Content and Language Integrated Learning in OpenSimulator Project-CLILiOP. Content and Language Integrated Learning together with constructivism provided the theoretical basis of the project. A multi-user virtual environment was developed using OpenSimulator, which entailed a tour of…

EvoluZion is a forward-in-time genetic simulator developed in Java and designed to perform real time simulations on the evolutionary history of virtual organisms. These model organisms harbour a set of 13 genes that codify an equal number of phenotypic features. These genes change randomly during replication, and mutant genes can have null,…

In this article, we demonstrate limitations of accessibility of information in visual working memory (VWM). Recently, cued-recall has been used to estimate the fidelity of information in VWM, where the feature of a cued object is reproduced from memory (Bays, Catalao, & Husain, 2009; Wilken & Ma, 2004; Zhang & Luck, 2008). Response…

The authors write that the longer they study and work in organizations, the more they discover power to be one of the central issues which researchers and students must understand. Researchers who ignore power run the risk of spurious, irrelevant findings. Students who assume administrative positions without a proper understanding of power and how…

This paper presents the development phase of the of the Virtual World that is going to be used by the Virtual Learning for People with Autistic Spectrum Disorder (VL4ASD) project, which aims to create training materials on conversation skills. This project is geared towards addressing the communication deficits of ASD populations, by exploring the…

This article reports on a Monte Carlo simulation study, evaluating two approaches for testing the intervention effect in replicated randomized AB designs: two-level hierarchical linear modeling (HLM) and using the additive method to combine randomization test "p" values (RTcombiP). Four factors were manipulated: mean intervention effect,…

Surveys play an important role in understanding the higher education landscape. About 60 percent of the published research in major higher education journals utilized survey data (Pike, 2007). Institutions also commonly use surveys to assess student outcomes and evaluate programs, instructors, and even cafeteria food. However, declining survey…

This study has been carried out within the context of the ECO European Project (E-learning, Communication Open-Data: Massive Mobile, Ubiquitous, and Open Learning) which is being financed by the European Union over four years (2014-17). It analyses the pedagogic architecture of MOOC on pedagogic/educational subjects in Spanish over one academic…
