Cybercrimes in the aftermath of COVID-19: Present concerns and future directions
Cybercrimes are broadly defined as criminal activities carried out using computers or computer networks. Given the rapid and considerable shifts in Internet use and the impact of the COVID-19 pandemic on cybercrime rates, online behaviours have attracted increased public and policy attention. In this article, we map the landscape of cybercrime in the UK by first reviewing legislation and policy, as well as examine barriers to reporting and address investigative challenges. Given the indisputable rise in cybercrime and its mental health impacts, we propose a four-facet approach for research and practice in this field with an eye to systemic shifts and strategies to combat cybercrime holistically: community alliances and social support, state intervention, and infrastructural sensitivity to user diversity. Lastly, empirical evidence from research guides the design of data-driven technology and provision of advice/interventions to provide a safer digital landscape — hence the importance for more informative research
Feasibility and Detailing of Post-tensioned Timber Buildings for Seismic Areas
Paper 53This paper describes the structural design and selection of construction
detailing for low-rise multi-storey timber buildings using a new and exciting structural
timber system. This system, originally developed for use with pre-cast concrete,
combines the use of un-bonded post-tensioning techniques and additional sources of
energy dissipation. This system eliminates residual displacement, while greatly reducing
the damage to structural members during a significant seismic event. The paper shows
how this new structural system can be used with large size structural timber members
manufactured from laminated veneer lumber (LVL) or glulam timber, for use in multistorey
buildings, with lateral load resistance provided by post-tensioned structural timber
frames or walls, separately or in combination.
An extensive on-going research program at the University of Canterbury, New Zealand
has tested a wide range of beam-to-column, wall-to-foundation and column-to-foundation
connections under simulated seismic loading, all giving excellent results.
As part of this contribution, a case study of the design methods, construction options, cost
and feasibility of a six storey timber office building in a moderate seismic area is carried
out. The structural design of this building allowed investigation of different methods of
structural analysis, and the development of many construction and connection details
offering feasibility of rapid construction. Total building cost was evaluated and compared
to equivalent steel and reinforced concrete options
Search for antiproton decay at the Fermilab Antiproton Accumulator
A search for antiproton decay has been made at the Fermilab Antiproton
Accumulator. Limits are placed on thirteen antiproton decay modes. The results
include the first explicit experimental limits on the muonic decay modes of the
antiproton, and the first limits on the decay modes e- gamma gamma, and e-
omega. The most stringent limit is for the decay mode pbar-> e- gamma. At 90%
C.L. we find that tau/B(pbar-> e- gamma) > 7 x 10^5 yr. The most stringent
limit for decay modes with a muon in the final state is for the decay pbar->
mu- gamma. At 90% C.L. we find that tau/B(pbar-> mu- gamma) > 5 x 10^4 yr.Comment: 20 pages, 8 figures. Submitted to Phys. Rev. D. Final results on 13

Life History and Narrative Analysis: Feminist Methodologies Contextualizing Black Women\u27s Experiences with Severe Mental Illness
This paper discusses a methodological approach to research that enhances critical analysis by contextualizing qualitative research findings within participants\u27 individual experiences. We demonstrate the combined use of life history methods and feminist narrative analysis to explore Black women\u27s everyday experiences with mental illness, from their perspectives. These interpretive methods reach beyond pathologized conceptions of identity and adjustment that often narrowly characterize mental illness among Black women. Instead, these methods holistically describe a participant\u27s experiences and strategies she uses to pursue goals and enhance her life. The use of the methods is illustrated with examples from the life narrative of Maria, a Black woman living with serious mental illness. Our findings underscore the need for rigorous, culturally appropriate methods and further research to evaluate participants\u27 standpoints and needs, and interventions to facilitate understanding and improved outcomes
Search for muonic decays of the antiproton at the Fermilab Antiproton Accumulator
A search for antiproton decay has been made at the Fermilab Antiproton
Accumulator. Limits are placed on six antiproton decay modes which contain a
final-state muon. At the 90% C.L. we find that
tau/B(mu gamma) > 5.0 x 10^4 yr,
tau/B(mu pi0) > 4.8 x 10^4 yr,
tau/B(mu eta) > 7.9 x 10^3 yr,
tau/B(mu gamma gamma) > 2.3 x 10^4 yr,
tau/B(mu K0S > 4.3 x 10^3 yr, and
tau/B(mu K0L) > 6.5 x 10^3 yr.Comment: 8 pages + 3 Postscript figure
Synchronization reveals topological scales in complex networks
We study the relationship between topological scales and dynamic time scales
in complex networks. The analysis is based on the full dynamics towards
synchronization of a system of coupled oscillators. In the synchronization
process, modular structures corresponding to well defined communities of nodes
emerge in different time scales, ordered in a hierarchical way. The analysis
also provides a useful connection between synchronization dynamics, complex
networks topology and spectral graph analysis.Comment: 4 pages, 3 figure
Bubble Growth in Superfluid 3-He: The Dynamics of the Curved A-B Interface
We study the hydrodynamics of the A-B interface with finite curvature. The
interface tension is shown to enhance both the transition velocity and the
amplitudes of second sound. In addition, the magnetic signals emitted by the
growing bubble are calculated, and the interaction between many growing bubbles
is considered.Comment: 20 pages, 3 figures, LaTeX, ITP-UH 11/9
