Revision with unchanged content. This study investigated the influence of computer-generated reminders on the rate in which distance learners submitted assignments and completed courses. The computer-generated reminders, sent via email, served as a time management support strategy. Participants were randomly divided into two groups: control and treatment. Both groups received a list of target due dates for course assignments. The control group did not receive reminders. The treatment group received reminders when they failed to submit an assignment by a target due date. The results indicated no significant difference between the control and treatment groups in terms of assignment submission rates and course completion rates. However, results of this study did reveal that the number of assignments in a distance course influences the timeliness of assignment completion and the likelihood of course completion.
This study is situated within the field of instructional design and sought to identify competencies specific to online designers-by-assignment in high school learning environments. Since existing instructional design standards currently available to guide designers-by-assignment differ from one another, a lack of clarity remains about which specific standards actually benefit this emerging professional group in the process of developing and revising courses they eventually teach. The purpose of this qualitative Delphi study was to identify, through expert agreement, instructional design competencies that can benefit high school online designers-by-assignment and the instructional design profession. This study employed the qualitative Delphi design to achieve consensus among experts in five fields (high school online practitioners, instructional design academics, university pre-service instructors, online high school administrators and high school online instructional designers).
The focus area of this paper is on the assignment problem with budget constraints which is one of the application area of combinatorial optimization that operates on the domain of those optimization problems,in which the set of feasible solutions is discrete or can be reduced to discrete,and in which the goal is to find the best solution. It is particularly concerned with solving the unconstrained assignment problems with Hungarian algorithm and the constrained assignment problem by cutting plane or outer linearization algorithm for solving the Lagrangian dual problem in which, at each iteration,the function that approximates the dual function is optimized. The paper is divided in to two chapters. In the first chapter,the classical assignment problem,the problem of finding optimum (minimum or maximum) cost or profit assignment a set of workers or resources to jobs or activities to gather with its mathematical formulation,solution methods and special cases in assignment problems were considered. Under the second chapter, we have considered generalization of the classical assignment problem concerning resource(or budget) constraints, due to the variety of real life problems.
With a controversial presidential election just weeks away, Quarry is hired to carry out a rare political assignment: kill the Reverend Raymond Wesley Lloyd, a passionate Civil Rights crusader and campaigner for the underdog candidate. But when a hate group out of Ferguson, Missouri, turns out to be gunning for the same target, Quarry starts to wonder just who it is he’s working for.
Assignment Problem is one of the first fundamental problems in the area of combinatorial optimization. Despite its historical roots, the problem has tremendous importance to date, due to its numerous real life applications in like facility location, personnel scheduling, job scheduling, production planning, project assignment, task assignment, time-tabling, vehicle routing, storage space allocation, etc. This book comprises some real life assignment and related problems involving imprecise cost/time parameters. In order to represent those imprecise parameters, interval numbers have been used here as this representation is the best among others. The associated problems have been solved using Genetic Algorithm efficiently. A salient feature of this book is that most of the algorithms have been written in a lucid manner with suitable examples using figures. This book should interest academicians, OR/GA practitioners and executives of different industries and business organizations.
A wireless mesh networks (WMNs) has emerged recently, WMN consist of two types of nodes mesh routers and mesh clients.WMN is dynamically self-organized and self-configured, with the nodes in the network automatically establishing and maintaining mesh connectivity among themselves. Channel assignment is a critical issue in WMN which is the mapping between the available channels and the radios at each node such that the network performance is optimized, and hence the focus of this work along with static channel assignment, multi-radio, multi-channel. Multi-radio MAC can potentially achieve higher network capacity than single-radio MAC. We design and implement a new agent (DSBCA) distributed channel assignment spanner base, the routing protocol Optimize the network performance considering the throughput, end-to-end delay, connectivity and the interference of our channel assignment algorithm. Base on the network simulations NS2.34 on Linux Fedora and our proposed channel assignment algorithm improved the throughput, minimal-connectivity preserving channel assignment algorithm.
With an increasing amount of technology being incorporated into teachers’ lessons, there is need for research to be done so teachers can include technology in a way that most benefits students. Previous research has found that, in the university setting, implementing student written weblogs into ESL writing instruction and practice has shown improvement in the quality of student composition. The present study took place over six weeks, and included five intermediate level English language learners in a middle school setting. After receiving lecture-based instruction from the classroom teacher, each participant completed a writing assignment. The experimental group completed five assignments using a weblog created on EDUblogs.org for this study while the control group completed five writing assignments using a word processor or pen and paper. Each assignment was scored using an ESL composition profile by the classroom teacher. The results showed that the participants in the control group showed the most improvement in their writing scores.
The efficient management of Change Requests (CRs) is fundamental for successful software maintenance; however the assignment of CRs to developers is an expensive aspect in this regard, due to the time and expertise demanded. To overcome this, researchers have proposed automated approaches for CR assignment. Although these proposals present advances to this topic, they do not consider many factors inherent to the assignments, such as: developers’ workload, CRs severity, interpersonal relationships, and developers know-how. Actually, as we demonstrate in this work, CR assignment is a complex activity and automated approaches cannot rely on simplistic solutions. Ideally, it is necessary to consider and reason over contextual information in order to provide an effective automation. Beyond investigating all these aspects through an extensive systematic literature review, this work also proposes a context-aware architecture solution to semi-automated assignment of CRs.
The Evil Within: The Assignment – это первое из двух дополнение к The Evil Within, главной героиней которого является Джулия Кидман, напарница детектива Себастьяна Кастелланоса. В этом дополнении игроки получат часть ответов на те вопросы, которые у них остались после финала оригинальной игры.
