BCG-K@W Procurement Report: Part 8: Peformance-based Logistics
These days, when the U.S. Department of Defense buys a fighter jet from Lockheed Martin, it doesn't simply pay Lockheed for the physical product. Instead, the government has a "performance-based contract" with the defense supplier, according to Serguei Netessine, professor of operations and information management at Wharton. This contract says, in effect, that the government's reimbursement to Lockheed hinges on the jets' performance -- that is, how often the planes are able to fly. In this inte
AIG Rescued but Crisis Continues
After refusing to bail out Lehman Brothers, the government agreed to an $85 billion loan to insurance giant AIG, effectively taking over the company. Knowledge@Wharton talked to Wharton insurance professors Olivia Mitchell and Kent Smetters to find out how the world's largest insurer got into this situation and how it can be prevented from happening again.
BCG's Hal Sirkin on 'Globality' and the New Two-way Street of Global Business
According to Hal Sirkin, senior partner and managing director at The Boston Consulting Group, The age of globalization is over. In its place is a new reality that Sirkin and BCG colleagues Jim Hemerling and Arindam Bhattacharya define in their recently published book, GLOBALITY: Competing with Everyone from Everywhere for Everything. In an interview with Knowledge@Wharton, Sirkin describes how rapidly developing economies like India and China have changed global business from a one-way street be
Economists to Obama: Get the Government out of the Banking Business
On the eve of Barack Obama's inauguration as president of the United States, Wharton finance professor Richard J. Herring discussed with Knowledge@Wharton some of the advice offered to the new chief executive by the Shadow Financial Regulatory Committee, a group of economists, former regulators and lawyers, of which Herring is a co-chair. Among the recommendations: As quickly as possible, unwind federal investments that helped keep U.S. banks afloat. Herring also assessed the deepening woes at C
The Road to China: Fresh Insights into the World's Fastest-growing Economy
Earlier this year, Harbir Singh, Wharton’s vice-dean for Global Initiatives, launched a series of trips to foreign countries as a way for faculty to gain a deeper understanding of international economies and then use this knowledge in their teaching and research. Six professors recently visited the Chinese cities of Beijing, Shanghai and Shenzhen, and met with executives from Lenovo, Haier and Huawei, among other companies. Knowledge@Wharton asked three of the participants – Singh, m
Brazil's Gold: How Rio Won Its Olympic Bid
Last fall, after losing previous bids, Rio de Janeiro -- Brazil's second-largest city -- won the approval of the International Olympic Committee to host the 2016 Summer Olympic Games. According to Carlos Roberto Osorio, secretary general of the Brazilian Olympic Committee, this time around, Rio had learned from its earlier failed bids and had the success of hosting the 2007 Pan American Games under its belt. That, combined with Brazil's "special circumstances" of economic stability amid the glob
What Does the Drooping Book Business Need? How About a Jolt of Espresso?
What if you could print a perfect-bound volume for as little time as it takes to brew a cup of coffee? That is the premise behind the Espresso book machine, which turns digital PDF files into paperbacks in minutes. Jason Epstein and Dane Neller, chairman and CEO respectively of On Demand Books in New York, the company behind the Espresso book machine, believe their technology has the potential to transform book publishing. Epstein, who was editorial director of Random House for 40 years, recentl
27 Oct 2010: Arab Voices: What They are Saying to Us, and Why It Matters
James Zogby, Ph.D., is the founder and president of the Arab American Institute and a senior adviser with the polling firm Zogby International. He writes a weekly column appearing in 20 Arab newspapers and hosts a weekly call-in discussion program on Abu Dhabi television. Zogbys book Arab Voices: What They are Saying to Us, and Why It Matters reveals the results of the 2009-2010 Zogby International polls conducted across a number of Arab countries covering Arab opinions about America and the Mid
Students' performance and satisfaction with Web vs. paper-based practice quizzes and lecture notes
The use of computers to deliver course-related materials is rapidly expanding in most universities. Yet the effects of computer vs. printed delivery modes on students' performance and motivation are not yet fully known. We compared the impacts of Web vs. paper to deliver practice quizzes that require information search in lecture notes. Hundred and twenty two undergraduate students used either a web site or printed documents to answer 18 mathematics questions during a tutored session. A revised
Enabling Mobile Collaborative Learning through Multichannel Interactions
The work presented here shows an architecture to integrate multiple communication channels for a simple communication tool: a weblog. The motivation for this work is to enable learners to access learning services regardless of their situation. Indeed, in some cases the access to these services is quite hard because people are on the move or don't easily have access to an Internet connection. This article presents the different elements that fit into the architecture which lay the path for a rich
Digital astronomy in education
What causes seasons? Why day and night durations are so different with seasons alternation? Why the position of the full moon seems directed to the south in summer while it seems directed to the north in winter? It is the purpose of this computer simulation to provide an interactive application, programmed in Java language to explore the issues related to the above questions.
Participatory Design for Developing Web Services Supporting Learning in Communities of Practice: the
The paper aims at showing how Participatory Design contributes to the understanding of learning processes related to Communities of Practice (CoPs) and, at the same time, to the design and implementation of Web Services to support organisational and individual learning in CoPs. This research builds on the European PALETTE project.
Advantages and disadvantages of e-learning at the technical university
The term Electronic Learning or e-Learning is being used in Russia rather rarely. It integrates a number of terminological notions in the sphere of application of modern information and communication technologies in education such as multimedia, education on the base of web-technologies, etc. Teachers and learners must realize that new opportunities are offered by modern on-line communication. A person with basic Internet and Web skills is open to a new world of knowledge, from free Web surfing
Diagnostic models of intelligent tutor system for teaching skills to construct control object freque
In this paper one solution for teaching skills to construct the control object frequency characteristics method is described. Students mistakes are discovered and classified. Based on signal-parametric approach to fault diagnosis in dynamic systems mathematical diagnostic models which allow detecting mistake classes by comparing student calculated results and system calculated results are created. Features of proposed diagnostic models application are presented. Intelligent tutor system is dev
Challenges of implementing CSCL designs in the Greek classrooms

Co-Lab, design considerations for a collaborative inquiry learning environment
Co-Lab is a learning environment for collaborative inquiry learning in which learners can experiment, make models, consult background information and discuss their findings. The complex learning processes in such an environment need to be supported by appropriate features in the software. In this paper we report on how, based on existing literature and specific user and usability studies, we developed a set of design guidelines that were implemented in the software.
Four Easy Pieces: Development Systems for Knowledge-Based Generative Instruction
The Experimental Advanced Design Advisor (XAIDA) is a system for the development of computer-based maintenance training. XAIDA acquires knowledge of a device from a subject matter expert and applies common maintenance-training procedures to generate interactive training from the description. XAIDA provides maintenance training in four areas: the physical characteristics of a device, its theory of operation, operating and maintenance procedures, and troubleshooting. XAIDA relies on an instruction
