Sonification of Network Traffic Flow for Monitoring and Situational Awareness
Maintaining situational awareness of what is happening within a network is
challenging, not least because the behaviour happens within computers and
communications networks, but also because data traffic speeds and volumes are
beyond human ability to process. Visualisation is widely used to present
information about the dynamics of network traffic dynamics. Although it
provides operators with an overall view and specific information about
particular traffic or attacks on the network, it often fails to represent the
events in an understandable way. Visualisations require visual attention and so
are not well suited to continuous monitoring scenarios in which network
administrators must carry out other tasks. Situational awareness is critical
and essential for decision-making in the domain of computer network monitoring
where it is vital to be able to identify and recognize network environment
behaviours.Here we present SoNSTAR (Sonification of Networks for SiTuational
AwaReness), a real-time sonification system to be used in the monitoring of
computer networks to support the situational awareness of network
administrators. SoNSTAR provides an auditory representation of all the TCP/IP
protocol traffic within a network based on the different traffic flows between
between network hosts. SoNSTAR raises situational awareness levels for computer
network defence by allowing operators to achieve better understanding and
performance while imposing less workload compared to visual techniques. SoNSTAR
identifies the features of network traffic flows by inspecting the status flags
of TCP/IP packet headers and mapping traffic events to recorded sounds to
generate a soundscape representing the real-time status of the network traffic
environment. Listening to the soundscape allows the administrator to recognise
anomalous behaviour quickly and without having to continuously watch a computer
screen.Comment: 17 pages, 7 figures plus supplemental material in Github repositor
Building Quality Improvement Systems: Lessons from Three Emerging Efforts in the Youth-Serving Sector
Quality is fast becoming a policy priority in states and localities around the country. As a result, formal and informal networks of youth organizations are seeking and developing strategies to help them assess and improve performance. This report takes a close look at efforts underway in three networks and provides a preliminary framework for thinking about key questions when planning any kind of program quality improvement work in the youth-serving sector
Development and construction of China
Libraries in China's higher education institutions have been developing in keeping pace with the flourishing development of China's higher education. This article aims to make an introduction to the construction of China's higher education libraries, especially the recent three decades' achievements since China's reform and opening-up in 1978. In this article, the authors draw a general picture of the development of libraries in China's higher education institutions, covering such eight aspects as management, types and positioning, organizational structure and personnel, expenditure and buildings, reader service, building and sharing of resources as well as automation system.</p
Further improvement of the implementation of the Aarhus convention in Malta : a review
Chapter 2Th e Twinning project MT/06/IB/EN/01 “Further Institution Building in the
Environment Sector” aimed at supporting the Maltese Government in improving
the implementation of the Aarhus Convention on public access to environmental
information, public participation in environmental decision making and access to justice
in environmental matters.
Th e project was carried out by MEPA as Benefi ciary Institution and the Austrian
Environment Agency as Lead Member State Partner. Th e project duration was 15 months
as from 16th April 2008. Th e project was co-funded by the European Union and the
Maltese Government under the 2006 Transition Facility Programme for Malta.
Th e project consisted of four components:
• Component 1: Assessment of the current situation and development of
recommendations,
• Component 2: Implementation of recommendations,
• Component 3: Development of guidance documents,
• Component 4: Training and awareness-raising.
In Component 1, the legal instruments and institutional arrangements in place for the
implementation of the Aarhus Convention in Malta were assessed, and recommendations
were drawn up on how to improve the existing situation with regard to public access to
environmental information, public participation in environmental decision-making and
access to justice in environmental matters.
In Component 2, the recommendations were discussed with a wide range of
stakeholders, and consequently applied in the practice, establishing an effi cient and
eff ective administrative system to implement the Aarhus Convention. Amongst other measures, its implementation formulated a series of agreements between the benefi ciary
and key holders of environmental information in Malta, with the aim of securing
the availability, timeliness and quality of environmental data, supported by effi cient
information management systems.
In Component 3, guidelines were produced addressing the public authorities, the
industry and the general public in Malta.
Component 4 provided training for public offi cers and awareness-raising for key
stakeholders and the general public.
The most relevant project results are summarised in this chapter, as achieved under each
Component.peer-reviewe
Discriminatory fees, coordination and investment in shared ATM networks
This paper empirically examines the effects of discriminatory fees on ATM investment and welfare, and considers the role of coordination in ATM investment between banks. Our main findings are that foreign fees tend to reduce ATM availability and (consumer) welfare, whereas surcharges positively affect ATM availability and the different welfare components when the consumers' price elasticity is not too large. Second, an organization of the ATM market that contains some degree of coordination between the banks may be desirable from a welfare perspective. Finally, ATM availability is always higher when a social planner decides on discriminatory fees and ATM investment to maximize total welfare. This implies that there is underinvestment in ATMs, even in the presence of discriminatory feesinvestment, coordination, ATMs, network industries, empirical entry models, spatial discrete choice demand models
Handbook for Implementing a Comprehensive Work-Based Learning Program According to the Fair Labor Standards Act
This Handbook for Implementing a Comprehensive Work-Based Learning Program According to the Fair Labor Standards Act provides guidance to schools operating WBL programs and encourages the adoption of WBL programs by schools not presently using this approach. By following the information and examples in this handbook, schools can proceed with confidence to operate effective WBL programs consistent with the FLSA

Comparing air quality among Italy, Germany and Poland using BC indexes
In this paper we discuss air quality assessment in three Italian, German and Polish regions using the index methodology proposed in Bruno and Cocchi (2002, 2007). This analysis focuses first of all on the quality of the air in each of the countries being taken into consideration, and then adopts a more general approach in order to compare pollution severity and toxicity. This is interesting in a global European perspective where all countries are commonly involved in assessing air quality and taking proper measures for improving it. In this context, air quality indexes are a powerful data-driven tool which are easily calculated and summarize a complex phenomenon, such as air pollution, in indicators which are immediately understandable. In particular, the main objective of this work is to evaluate the index performances in distinguishing different air pollution patterns. This kind of analysis can be particularly useful, for example, in the perspective of constructing an indicator of air pollution. --
