Digital age: challenges for libraries
Information technology and globalization are the two most influential forces of the modern times. IT has given new meanings to the transmission, dissemination and storage of information; whereas globalisation is reducing the importance of geographical boundaries. Libraries as an important social institution have been affected by these changes. Information retrieval, information storage and information transmission are the core competencies of the libraries. Digital age characterized by efficient graphic user interface, digital imaging, efficient transfer and storage of texts, is presenting important challenges for the libraries. Information privacy, copyrights, and information security are some of the challenging issues faced by the libraries in digital age. This paper is an attempt to present as well as to discuss the implications of these issues so that strategies can be devised to address them effectively and efficiently
Making defeating CAPTCHAs harder for bots
For a number of years, many websites have used CAPTCHAs to filter out
interactions by bots. However, attackers have found ways to circumvent CAPTCHAs
by programming bots to solve or bypass them, or even relay them for humans to
solve. In order to reduce the chances of success of such attacks, CAPTCHAs can
be strengthened by the addition of certain safeguards. In this paper, we
discuss seven existing safeguards as well as five novel safeguards designed to
make circumventing CAPTCHAs harder. These safeguards are not mutually exclusive
and can add multiple layers of protection to a CAPTCHA. We further provide a
high-level comparison of their effectiveness in addressing the threat posed by
CAPTCHA-defeating techniques. In order to focus on safeguards that are usable,
we restrict our attention to those which have minimal adverse effect on the
user experience
One leak will sink a ship:WebRTC IP address leaks
The introduction of the WebRTC API to modern browsers has brought about a new
threat to user privacy. This API causes a range of client IP addresses to
become available to a visited website via JavaScript even if a VPN is in use.
This a potentially serious problem for users utilizing VPN services for
anonymity. In order to better understand the magnitude of this issue, we tested
widely used browsers and VPN services to discover which client IP addresses can
be revealed and in what circumstances. In most cases, at least one of the
client addresses is leaked. The number and type of leaked IP addresses are
affected by the choices of browser and VPN service, meaning that
privacy-sensitive users should choose their browser and their VPN provider with
care. We conclude by proposing countermeasures which can be used to help
mitigate this issue
A strategic perspective on the emergence and evolution of e-Banking in Saudi Arabia
The aim of the thesis is to look at the emergence and evolution of e-banking in Saudi Arabia, with
particular emphasis on the processes of how banks implement e-banking to build their capabilities and
create new value strategies. The research process focuses on understanding (1) how banks implement
e-banking to build their capabilities as well as to create new value strategies, (2) how e-banking
capabilities have been built, and (3) the role played by e-banking in shaping the strategic direction of
banks. This requires understanding of a variety of aspects (i) the value created by e-banking products
and services within different banks, (ii) the process of e-banking development within the different
banks, (iii) how banks approach e-banking products and services, and (iv) how the banks align the
demand and supply factors surrounding e-banking products and servicesThe theoretical approach blends inputs from different disciplines relevant to understand and deal with
the subject matter of this thesis, including value creation and capability-building literature, technology
implementation literature, with particular emphasis on the processes of implementing network
technologies and e-businesses, as well as literature on process approaches. The methodological
approach makes use of the case study strategy (Yin 2003) as research strategy, a multiple-case
embedded design, as research design strategy, and three sources of evidence: (1) a survey distributed
to all Saudi Arabian banks, (2) semi-structured interviews, and (3) archival records of e-banking
transactions. The main fieldwork is longitudinal and takes place during three rounds: SeptemberOctober 2003, December 2003-March 2004, and December 2005-January 2006.The thesis investigates the emergence and evolution of e-banking at six Saudi Arabian banks: Samba
Financial Group (Samba), AlRajhi Bank (AlRajhi), Saudi Investment Bank (Saib), Saudi Hollandi
Bank (Hollandi), National Commercial Bank (AlAhli), and Riyad Bank (Riyad). This is followed by
an investigation of the emergence and evolution of electronic securities trading systems at the Saudi
Capital Market (i. e., Tadawul), providing an external view of the emergence and evolution of ebanking in Saudi Arabia.The analysis of the empirical material implements the theoretical propositions strategy via utilisation
of the "sociotechnical constituencies" approach (Molina 1990; 1993) and its associated analytical
tools of the "diamond of alignment" (Molina 1995), "alignment web" (Molina 2003) and "dynamic
strategy mapping" (DSM) (Molina 2005). The aim is not only to use the approach to reveal how banks
build their e-banking capabilities and create new value strategies, but also to test critically the
applicability of the "sociotechnical constituencies" approach and its associated analytical tools for
understanding e-banking value creation and capability-building strategies.The overall result of the investigation conducted by this thesis suggests that the Saudi Arabian ebanking' constituency-building process shows distinctive processes of sociotechnical alignment by
each one of the specific Saudi banks' e-banking constituencies in the study. In addition, the use of
Molina's "alignment web" to assess the state of each of the specific e-banking constituency-building
processes helps identify the areas of strengths and weaknesses in these processes of sociotechnical
alignment. The distinctiveness of development by each sociotechnical constituency is also highlighted
by the application of the Molina's "dynamic strategy mapping" (DSM), showing that each
constituency has its own combination of strategic ingredients.Although this thesis demonstrates strengths in the areas of logic replication, narrative writing, and
validating procedure, in future studies it would be interesting to enhance its theoretical background,
chronological structure, and quantitative assessment. This thesis contributes to providing a rich insight
into the emergence and evolution of e-banking in Saudi Arabia, particularly at six of eleven Saudi
banks as well as the technological systems of the Saudi Capital Market. Such contribution may be
used to inform the future alignment strategy pursued by each the Saudi Arabian e-banking
constituencies
Introducing conventional human resources practices as part of civil service reform in Qatar 2006-2016
Qatar in the Arabian Gulf is one of many states worldwide trying to improve governance. In 2008, Qatar introduced various ‘human resources management (HRM) practices to improve management of employees. However, there is a growing belief that importing undiluted systems based on other cultures may potentially erode local Arab culture significantly and harmfully. The research project aimed to evaluate if Government Ministries in Qatar can use principally Western HRM theory and practice to manage employees successfully while still allowing them to preserve and strengthen Arab and Islamic values and identity.
Some months into the project which commenced in 2006, the State initiated further major reforms and introduced new Ministers and top executive teams in each of 13 newly created Ministries. This created much additional noise in the data making it difficult to separate the effects of wider reforms from those caused by new HRM practices.
Given the difficulties of using more conventional statistical analysis techniques, research then adopted a Mixed-Methods Exploratory Sequential Research Design the research completed extensive and detailed research into HRM systems in place in each Ministry. It also collected data and information about perceptions of executives about HR reforms, leadership and management style and other salient factors.
The research reached eleven important findings. Among these, the findings showed the people management systems bore much closer resemblance to classic personnel management system. This negated any likely benefits of introducing HRM. The findings also found considerable differences between the national culture of Qatar and that of the West, from where the State drew many of its new ideas for reform. Adoption of such culturally dissimilar systems had the potential to offset efforts to preserve the Gulf’s highly distinctive culture. The work also make practical recommendations with which reform efforts could be improved, though not at the expense of local culture. The thesis completes with recommendations for further research
