Design Piracy: the Extensive Impact of a Fashion Knockoff
On the Monetary Impact of Fashion Design Piracy Gil Appel Marshall School of Business, University of Southern California [email protected] Barak Libai Arison School of Business, Interdisciplinary Center (IDC), Herzliya [email protected] Eitan Muller Stern School of Business, New York University Arison School of Business, Interdisciplinary Center (IDC), Herzliya [email protected] July 2017 The authors would like to thank Roland Rust, Senior Editor and reviewers, On Amir, Michael Haenlein, Liraz Lasry, Irit Nitzan, Raphael Thomadsen, the participants of the Marketing Science and EMAC conferences and the participants of the seminars of the business schools at University of California at Davis, the University of California at San Diego, and Stanford University for a number of helpful comments and suggestions. On the Monetary Impact of Fashion Design Piracy Abstract Whether to legally protect original fashion designs against design piracy (“knockoffs”) is an ongoing debate among legislators, industry groups, and legal academic circles, yet to-date this discussion has not utilized marketing knowledge and formal approaches. We combine data collected on the growth of fashion items, price markups, and industry statistics, to create a formal analysis of the essential questions in the base of the debate. We distinguish between three effects: Acceleration, whereby the presence of a pirated design increases the awareness of the design, and thus might have a positive effect on the growth of the original; Substitution, which represents the loss of sales due to consumers who would have purchased the original design, yet instead buy the knockoff; and the loss due to Overexposure of the design that follows the loss of uniqueness due to the design becoming too popular, causing some consumer not to adopt the design or stop using it. -
Software Design Document 1
SOFTWARE DESIGN DOCUMENT 1. Introduction The following subsections of the Software Design Document (SDD) should provide an overview of the entire SDD. 1.1 Purpose This subsection should explain the purpose of the SDD and specify the intended audience for it. The SDD described the software structure, software components, interfaces and data necessary for the implementation phase. Each requirement in the SRS should be traceable to one or more design entities in the SDD. 1.2 Scope This subsection should relate the design document to the SRS and to the software to be developed. 1.3 Definitions, Acronyms and Abbreviations This subsection should provide the definitions of all terms, acronyms and abbreviations that are used in the SDD. 2. References This subsection should provide a complete list of all documents referenced in the SDD. It should identify these references by title, report number, date and publishing organization. It should also specify the sources from which these references are available. 3. Attributes of Design Entities There are some attributes common to all entities, regardless of the approach utilized, whether procedural or object-oriented. These are used in subsections 4 and later. 3.1 Identification The name of the entity should be specified. Two entities should not have the same name. 3.2 Type The type attribute should describe the nature of the entity. It may simply name the kind of entity, such as subprogram, module, procedure, process, data item, object etc. Alternatively, design entities can be grouped, in order to assist in locating an entity dealing with a particular type of information. -
Change Orders Ordeal: the Output of Project Disintegration
International Journal of Business, Humanities and Technology Vol. 2 No. 1; January 2012 Change Orders Ordeal: The Output of Project Disintegration Roberto Soares, Ph.D., D.Sc., AIC, PE Assistant Professor College of Computing, Engineering and Construction University of North Florida Jacksonville, Florida United States of America Abstract Change orders are one of the most controversial issues in construction contracts and require successful negotiations to avoid claims and possible litigation. Contractors, owners and architects behave differently when dealing with change orders. The aim of this paper is to demonstrate that change orders are the natural result of the disintegration of design and construction, which started in the US in 1893 with a Congressional Act formally separating the design and construction phases of a capital project .Delivery methods such as Design-Build (DB) and Construction Management at Risk (CMR), which are designed to mend the missing integration of design and construction and, consequently, eliminate the existence of change order conflict are proposed to recover the level of integration that existed at the time of the master builder. Key words: change orders, project integration, design-build, delivery methods 1. Introduction Change orders in construction are one of the most controversial issues to manage and a challenge to project management to satisfactorily resolve any change in order to avoid claims. Any construction contract is signed under the principle of “good faith,” which means that the parties will trust each other to perform according to the contract and that the contract is fair with no intention of taking advantage of the parties during the life of the contract. -
Software Design Document (SDD) Template
Software Design Document (SDD) Template Software design is a process by which the software requirements are translated into a representation of software components, interfaces, and data necessary for the implementation phase. The SDD shows how the software system will be structured to satisfy the requirements. It is the primary reference for code development and, therefore, it must contain all the information required by a programmer to write code. The SDD is performed in two stages. The first is a preliminary design in which the overall system architecture and data architecture is defined. In the second stage, i.e. the detailed design stage, more detailed data structures are defined and algorithms are developed for the defined architecture. This template is an annotated outline for a software design document adapted from the IEEE Recommended Practice for Software Design Descriptions. The IEEE Recommended Practice for Software Design Descriptions have been reduced in order to simplify this assignment while still retaining the main components and providing a general idea of a project definition report. For your own information, please refer to IEEE Std 10161998 1 for the full IEEE Recommended Practice for Software Design Descriptions. 1 http://www.cs.concordia.ca/~ormandj/comp354/2003/Project/ieeeSDD.pdf Downloaded from http://www.tidyforms.com (Team Name) (Project Title) Software Design Document Name (s): Lab Section: Workstation: Date: (mm/dd/yyyy) Downloaded from http://www.tidyforms.com Software Design Document TABLE OF CONTENTS 1.

Theoretically Comparing Design Thinking to Design Methods for Large- Scale Infrastructure Systems
The Fifth International Conference on Design Creativity (ICDC2018) Bath, UK, January 31st – February 2nd 2018 THEORETICALLY COMPARING DESIGN THINKING TO DESIGN METHODS FOR LARGE- SCALE INFRASTRUCTURE SYSTEMS M.A. Guerra1 and T. Shealy1 1Civil Engineering, Virginia Tech, Blacksburg, USA Abstract: Design of new and re-design of existing infrastructure systems will require creative ways of thinking in order to meet increasingly high demand for services. Both the theory and practice of design thinking helps to exploit opposing ideas for creativity, and also provides an approach to balance stakeholder needs, technical feasibility, and resource constraints. This study compares the intent and function of five current design strategies for infrastructure with the theory and practice of design thinking. The evidence suggests the function and purpose of the later phases of design thinking, prototyping and testing, are missing from current design strategies for infrastructure. This is a critical oversight in design because designers gain much needed information about the performance of the system amid user behaviour. Those who design infrastructure need to explore new ways to incorporate feedback mechanisms gained from prototyping and testing. The use of physical prototypes for infrastructure may not be feasible due to scale and complexity. Future research should explore the use of prototyping and testing, in particular, how virtual prototypes could substitute the experience of real world installments and how this influences design cognition among designers and stakeholders. Keywords: Design thinking, design of infrastructure systems 1. Introduction Infrastructure systems account for the vast majority of energy use and associated carbon emissions in the United States (US EPA, 2014). -

Combining Design by Contract and Inference Rules of Programming Logic Towards Software Reliability
Combining Design by Contract and Inference Rules of Programming Logic towards Software Reliability Nuha Aldausari*, Cui Zhang and Jun Dai Department of Computer Science, California State University, Sacramento, CA 95819, U.S.A. Keywords: Software Security, Software Reliability, Program Specifications, Error Detection, Design by Contract, Programming Logic. Abstract: Detecting errors in software products is very important to software reliability because many security vulnerabilities are caused by the defects in software. Design by contract (DBC) is an effective methodology that dynamically checks whether a program meets its specifications, which are also called design contracts, and whether there are errors in the program. The contracts for object-oriented programs are defined in terms of preconditions and postconditions for methods as well as invariants for classes. However, if there is an error in a large piece of code that has a design contract, it is still difficult to identify the exact location of that error. To address this issue, a tool named Subcontractor has been developed. Subcontractor is implemented in Eclipse environment using libraries such as Java Development Tools (JDT), Plugin Development Environment (PDE), and JFace. The tool Subcontractor is built upon an open source DBC tool, OpenJML Runtime Assertion Checking (RAC), which is a tool that verifies specifications at runtime. Subcontractor combines this DBC tool with inference rules of program logic for if-statements and loop- statements to automatically generate subcontracts for programs. When the programs, with subcontracts automatically generated and inserted by Subcontractor, are verified using OpenJML Runtime Assertion Checking (RAC), identification of errors in the code can be facilitated. 1 INTRODUCTION (University of Oldenburg, 2001), and Contracts for Java (C4J) (Bergström, 2012).
