The earthquake and tsunami to devastate northeastern Japan in March 2011 remains the world's natural disaster to hit a developed country to date. As part of the recovery, enormous effort has been focussed on rebuilding the communications networks involved. For the first time in English, a comprehensive article is available detailing many behind the scenes aspects and many interviews with the leading players in the communications recovery. The scale of this disaster recovery effort and preparations and protection pose major questions not merely for technology but also for public policy and regulation globally. The article was published in December 2011 in Intermedia, the world's most influential journal focussing on digital media policy and regulation. Intermedia is published by the International Institute of Communications. IIC is a global membership, independent, non profit body focussing on critical issues in media and telecom policy worldwide. The article was written by Stephen McClelland, Intermedia Editor in Chief.
Dr Raul Katz of the Columbia Business School, USA, discusses national approaches to broadband rollouts and concludes most plans consist of one or more of three models, strategic planning, stimulus, or state intervention that are characterized in goal and intervention model. The presentation makes reference to the national broadband policies of USA, Australia, Singapore, Germany, Sweden, Portugal, Ireland, Canada, Finland and New Zealand amongst others.
Taylor Reynolds, a specialist analyst at OECD, argues that broadband is a once in a lifetime development for society, and a once in a generation upgrade, akin to the deployment of electricity. He points out against this background that competition forces have served the wider objectives of national broadband policies in terms of consumer-friendly pricing and ever higher speeds (particularly seen in the clear disappearance of broadband speed capping practices) around the world well.

A tsunami is a series of waves that are brought about by an earthquake in the sea or any other volcanic eruption. Tsunamis have happened since the creation of the world. Major Tsunamis are caused by earthquakes that happen after the collision of tectonic plates (Samuels). Some plates are too hard to be pushed when a collision occurs they release energy causing seismic waves. These sudden seismic waves lead to an earth shake. Tsunamis can be very dangerous to the dwellers of the seashore (Taylor). Tsunamis that have happened have been recorded to cause deaths and loss of property. For instance, the largest Tsunami to occur was in Sumatra in 2004 which had a magnitude of 9.1 and left over 230,000 people dead. The Tsunami that happened in 2011 in Japan was devastating and resulted in loss of many lives. Property of approximately 300billion dollars was damaged by the earthquake and tsunami. People drowned and most of them died. Many pictures were taken to keep a memory of what happened. This Tsunami was very large and impacted a lot to the Japanese government.
Many publications have been made about the historic 2011 earthquake, tsunami and subsequent nuclear accident that occurred in Japan. The magnitude of the earthquake was 8.9. Authors and photographers have published many articles with photographs of the tragedy, commonly referred to as "3/11". The earthquake hit the Tohoku region of Japan (BBC news). It swept away the entire town, killed thousands of dwellers and triggered a nuclear meltdown at the Fukushima Daiichi Nuclear Power Plant. Many damages were mostly along the coastline. The photo shows a wave that resulted from the tsunami earthquake as it approached Miyako City from the Heigawi estuary in Iwate Prefecture. The picture was taken on March 11, 2011, published in the Mainichi Shimbun. The photo shows the wave sweeping everything on the coastline including vehicles and houses. In the ocean, ships are seen as they are carried away, and others stack in the water. Some part of the city is submerged by the waters. The wave looks very strong and fast approaching, carrying and destroying everything on its way. This part was one of the most affected parts by the tragedy. Much of the town city was destroyed. The photo is just representation of how the deadly waves approached the cities in Japan destroying people and properties.
The earthquake in Tohoku 2011, struck the offshore of Japan beside a subduction zone where two tectonic plates were colliding. A subduction zone is where one plate slides below the other into the mantle which is the hotter layer below the crust. A recent study found out that, the Pacific plate which is in the east of Japan slides beneath the Eurasian plate (Samuels). On 11th March, 2011 an earthquake started at around 2.46pm on Friday local time. The earthquake was centered on the seafloor 72 kilometers in the East of Tohoku. It was felt in a depth of 24 kil ...

Daniel Arias of Telefonica Internacional argues that Latin America is a major success story in telecom and currently undergoing revolutionary progress in both fixed and mobile broadband in terms of deployment and penetration. Content is increasingly becoming available driven by many creative cultural reasons in Latin America and the Hispanic approach. Governments have been active in setting national broadband policies - and countries such as Brazil and Chile have placed substantial emphasis on these - but he points out broadband success will continue to come from a competitive private sector environment and although there is a role for government intervention it should be limited to those areas beyond the reach of the private sector.
Paul Kenefick, Vice President at Alcatel-Lucent in the US, says that all available analysis projects massive growth in broadband services, particularly in mobile broadband, but that users will continually be seeking more as third party content and applications also booms. The communications industry is moving fundamentally from a service provider-centric model to a user-centric model. The US needs coherent broadband policymaking that will drive sustainable private sector activity but analyses need to look beyond simple penetration levels into other factors. International comparisons are also relevant.
James Speta of the North Western University School of Law argues that in the future, we face an effective reality of unlimited video channels. Media regulation will be therefore complex as traditional media regulation affected content indirectly by regulating market structure but the unlimited channel scenario suggests that this will be less effective because unlimited channels will reduce the market structure effect. This has significant implications for subsidy policies in content creation and distribution. Subsidies may still be needed if non-economic goals are important but the outcome may well be to reduce the politics of subsidies.
Carlos Lopez Blanco of Telefonica discusses a re-evaluation of "convergence" which has promised much but delivered little. Broadband must be seen as the key provision in convergence whilst policymakers need to overcome real challenges including a consistent enforcement of net neutrality principles, a strengthening of consumer trust and control and an alignment of international policy in data privacy and processing.
Reinhald Krueger of the European Commission summarizes the complex transition to a future regulatory environment in communications. Europe's new legislative package includes the provision for independent regulators, reinforced oversight, a fundamental transition to a competition-law only regime, a functional separation remedy and a specific EU body - BEREC. Increased regulatory consistency, more work on access products, and changes to broadband market regulation are also on the horizon.
Lawson Hunter argues changes needed for the policy environment particularly as regards broadcasting in an environment which has changed from over the air to wired IP archictecture and applications
Gabrielle Gauthey of Alcatel-Lucent reviews and compares regulatory initiatives and experiences concerned with broadband deployments around the world and particularly between the US and Europe and predicts outcomes

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy.

temporarily slumped to 36% of its pre-earthquake figure (see graphic).
In some cases, restoration (through emergency rerouting of traffic from the affected cables onto other systems
around the Pacific), was able to ameliorate the service disruption. Overall capacity was increased to around 70% of
its pre-disaster levels by this means within 6 days of the disaster. Longer term restoration however required major
repairs to the damaged cable systems involving specialist ships to haul the cable systems up from the ocean floor

Time for organizational DNA?
As part of its own identity, NTT East has attempted to embody its corporate values and
this need for evolution in what it calls Tsunagu DNA [Connecting DNA], essentially a short-
form description of what the company stands for. Tsunagu DNA refers to a connection
with customers and particularly employees using organizational knowledge, capability,
and attitude: reaching perhaps an almost emotional engagement. Masahide Oka says “As
a carrier, connectivity is the main mission of this company…we are trying to pass the idea
of Tsunagu DNA down through the company.” Other managers agree. “The brand [of
Tsunagu DNA],” says Takashi Ebihara, “means NTT East will connect anyone, anywhere
at any time.” But the Tsunagu DNA attitude in a time of crisis seems to reduce corporate
operations often involving complex and troubling demands to very deep and core values that managers can clearly
depict and use to engage a sense of overriding mission.
Tsunagu DNA may be a brand, but branding in this case seems to go well beyond ‘normal’ mission statements,
helpful straplines or catchy marketing messages that many organizations use – and often use superficially without
thinking. In Fukushima, for example, a major part of Naoki Shibutani’s task, he says, has been the support of morale
of the reconstruction workers in difficult conditions. Working in the face of enormous challenges has significant
implications for organizational management practice and even the rights given and taken, expected and implied,
between employer and employee. He continues: “Sometimes the hardship [here] is indeed very hard, and our staff
may worry about their personal conditions, so it is important we improve attitudes and atmosphere. There are
hundreds of very brave people who have sacrificed their family life [by working away from home] and these people
are much admired,” points out Mr Shibutani.
But, he says, it comes back to the Tsunagu DNA concept and values – connecting with teams and transferring the
skillsets to others. Fundamental management challenges remain however at all levels. He continues: “When the
field workers retire – we lose about a hundred workers annually – we lose their ‘DNA’, because only 30 workers
are inbound to replace them, and these new workers will require extensive training. Outsourcing is also a concern
because we do not manage these workers directly and perhaps we effectively may have started to lose our own
skills.” Mr Ebihara agrees that senior management have been rethinking the outsourcing strategies the group has
pursued in recent years for operational efficiencies: “Top management now believe that holding these skillsets will
make the company run more reliably.”
