A comprehensive yet comprehensible and witty guide to the latest advances in computer network security protocols. The author team includes Charlie Kaufman, currently chief security architect for Lotus Notes, and formerly Network Security Architect at Digital Equipment Corporation;
This module provides students with an overview of cryptography and digital
certificates. The module then explains how students can protect data and
communications between the Web browser and the Web server. After
completing this module, students will be able to protect the portions of a Web
application that require private communications through Secure Sockets Layer
Information and communication technologies based on the Internet
have enabled the emergence of new sorts of communities and communicative
practices—phenomena worthy of the attention of anthropological researchers. Despite
early assessments of the revolutionary nature of the Internet and the enormous
transformations it would bring about, the changes have been less dramatic and more
embedded in existing practices and power relations of everyday life.
his report is part of the RAND Corporation monograph report series. The monograph/report was a product of the RAND Corporation from 1993 to 2003. RAND monograph/reports presented major research findings that addressed the challenges facing the public and private sectors. They included executive summaries, technical documentation, and synthesis pieces.
Chapter 13 - The internet. In this chapter we first give a brief history of the Internet. We formally introduce the TCP/IP protocol suite (Internet model) that we used as a networking model throughout the book. We then discuss briefly the next generation protocol. Access to the Internet, both residential and organizational, is also discussed. Finally we introduce private networks, intranets, and extranets.
Chapter 14 - Network security: Firewalls and VPNs. In this chapter, we look at four issues of security: privacy, authentication, integrity, and nonrepudiation. We show how the first can be achieved through secret-key or private-key encryption. We discuss a concept called digital signature that satisfies the three other conditions. We talk about how security is implemented in the Internet.
Slang is language deliberately selected for its striking informality and is consciously used in preference to ‘proper’ speech (or, more rarely, writing). It usually originates in small social groups. For
these groups, it is a private code that embodies their particular values and behaviour and reinforces their exclusivity. Slang expressions may escape the originating group and become more widely used, and although slang draws much of its effect from its novelty, some terms (booze, punk, cool) may stay in the language for many years....
Frame Relay has become the most widely used WAN technology in the world. Large enterprises, governments, ISPs, and small businesses use Frame Relay, primarily because of its price and flexibility.
•Moreover, Frame Relay provides greater bandwidth, reliability, and resiliency than private or leased lines.
•Frame Relay reduces network costs by using less equipment, less complexity, and an easier implementation.
This is a thought-provoking and invaluable book for anyone who
cares about risk communication and management in the 21st century.
Professor Löfstedt, via a number of case studies and the latest theoretical

Empirical evidence regarding international relative prices at the consumer level suggests that
arbitrage in international markets is not rapid and that these markets are highly segmented.
In fact, even markets for traded goods appear to be highly segmented internationally: In the
data, both real exchange rate movements and deviations from the law of one price for traded
goods are large and persistent.
Thus, the return gap captures the funds’ unobserved actions, which include
hidden beneﬁts and hidden costs.An important hidden beneﬁt results from
a fund’s interim trades, as discussed in Ferson and Khang (2002). Even
though we can observe fund holdings only at speciﬁc points in time, funds
may trade actively between these disclosure dates. If these interim trades
create value, then the fund return RF will increase, while the return of
the disclosed holdings RH will remain unaffected.
The dehesa is an ancient agrosilvopastoral system created by farmers to raise livestock,
mainly on private lands. This system is highly appreciated by society and enjoys legal
protection of the authorities because it is rich in biodiversity, a home to critically
endangered species (Iberian lynx, imperial eagle and black vulture); a significant carbon
sink; ethnologically and anthropologically valuable (culture and traditions); and is known
for its scenic value.
PUBLIC GOODS, PRIVATE INCENTIVES, AND AGRICULTURAL R&D: PRODUCTIVITY AND POVERTY IN DEVELOPING COUNTRY AGRICULTURE Like Baker, McMillan, and Reuben (2002), I identify parental valuations by the
location of clusters of high income families: If parental preferences over communities depend
exclusively on the effectiveness of the local schools, the most desirableand therefore
wealthiestcommunities are necessarily those with the most effective schools.
Twenty years ago, world leaders gathered at the Earth Summit in Rio de Janeiro and signed the
first global agreement to tackle climate change. At the time, the impacts of climate change on
communities and economies were just beginning to be understood, and the role of the private
sector in responding to these challenges was only just emerging. But two decades later, climate
change is no longer a distant threat looming on the horizon; it has emerged as arguably the
greatest global challenge of our time.
An investor in a forex fund should be sophisticated enough to understand the risks associated
with forex trading. Many investors would be interested in forex funds if they had the
opportunity. Because advertising of the fund and any other non-personal communications are
prohibited, and the media has touted the risks over the benefits, investors must be sought in more
direct and creative ways. A trader may find that in addition to family and close friends, many
colleagues and casual acquaintances may be potential investors.
Neither source of performance is particularly
correlated with the four Fama-French benchmarks, indicating that the private skills
identiﬁed by these predictability-based strategies are based on characteristics of funds that
are heretofore undocumented by the mutual fund literature.
The remainder of this paper proceeds as follows. Section 2 sets forth an econometric
framework for studying investments in mutual funds when business cycle variables may
predict future returns. Section 3 describes the data used in the empirical analysis, and
Section 4 presents the ﬁndings.

Decarbonising the world‟s energy system to avoid locking-in polluting technologies and unacceptably high
emission levels will require doubling existing investment levels to around USD 2 trillion a year or 2% of
GDP. Governments understand that large sums of capital will be required, and many are also realising the
need for further recourse to private capital as public finances have become strained in many developed
countries. Simultaneously, banking sector provision of long-term finance has become tighter due
deleveraging and new financial regulations.
The Reserve Fund was only the second MMMF to break the buck since the SEC adopted rules governing
these funds in 1983, with the first being the Community Bankers US Government Fund in 1994.
funds had losses significant enough to cause them to break the buck and sponsors that were unable to
provide non-contractual support to prevent the losses from being passed on to shareholders. However, it
was the lack of sponsor support for these two funds that was more unusual than the underlying losses
suffered, as credit events have impacted many more than two funds in the...
