"SMEs, Information Risk Management, and ROI"
Recent research in the area of standards accreditation has shown that the rate of take up of the ISO27001 (Information Security Management) by organisations been disappointing in many Western countries, compared to the picture emerging in Asia, and the rollout of previous international standards that relate to information management, such as ISO9001.
In this paper, a researcher and a practitioner from the UK investigate possible reasons for a lesser interest in pursuing certification for organisational Information Security Management Systems (ISMS) across Western countries. They also share their perceptions and concerns that current attitudes of UK of small businesses regarding complying with standards and legislation means that they may be taking unnecessary risks with their corporate and personal data under the possibly misguided notion that other priorities are more important during these current recessionary times.
The authors use an economics-based approach in proposing a solution to the problem. On the one hand they review the research that has provided methods for putting a figure on the value of corporate and personal data in larger organisations, and applying the principles of managing information risk as appropriate to SMEs. On the other hand they look at economics-related issues such as market pressure, insurance, outsourcing, and the legal and regulatory matters regarding privacy of personal data. The result provides a case for showing SMEs that, apart from the moral matter of being “good for the business”, there are very sound economic reasons for an SME developing an ISMS and getting ISO27001 certified
\u3ci\u3eDemocracy and Public Administration\u3c/i\u3e
Chapter 4, A Brief Tour of Public Organization Theory in the United States, authored by Gary S. Marshall, UNO faculty member.
The true measure of the successful practice of public service is its ability to remain faithful to the tenets of democratic society. This introductory text links the practice of public administration to the core concepts of American democracy. It covers the nuts and bolts of public administration in the context of delivering democracy in public service--providing what the public really wants as opposed to what self-serving bureaucracies may call for.
Chapters in Democracy and Public Administration discuss the functional topics covered in other texts, but from the perspective of this democratic ideal. Each chapter is written by an expert in the area, and summarizes previous research in the area, presents the author\u27s research and thought, and offers ways in which practitioners can apply the concepts discussed to their daily work.https://digitalcommons.unomaha.edu/facultybooks/1249/thumbnail.jp

The Kinetic Sunyaev-Zel'dovich Effect from Radiative Transfer Simulations of Patchy Reionization
We present the first calculation of the kinetic Sunyaev-Zel'dovich (kSZ)
effect due to the inhomogeneous reionization of the universe based on detailed
large-scale radiative transfer simulations of reionization. The resulting sky
power spectra peak at l=2000-8000 with maximum values of
l^2C_l~1\times10^{-12}. The peak scale is determined by the typical size of the
ionized regions and roughly corresponds to the ionized bubble sizes observed in
our simulations, ~5-20 Mpc. The kSZ anisotropy signal from reionization
dominates the primary CMB signal above l=3000. This predicted kSZ signal at
arcminute scales is sufficiently strong to be detectable by upcoming
experiments, like the Atacama Cosmology Telescope and South Pole Telescope
which are expected to have ~1' resolution and ~muK sensitivity. The extended
and patchy nature of the reionization process results in a boost of the peak
signal in power by approximately one order of magnitude compared to a uniform
reionization scenario, while roughly tripling the signal compared with that
based upon the assumption of gradual but spatially uniform reionization. At
large scales the patchy kSZ signal depends largely on the ionizing source
efficiencies and the large-scale velocity fields: sources which produce photons
more efficiently yield correspondingly higher signals. The introduction of
sub-grid gas clumping in the radiative transfer simulations produces
significantly more power at small scales, and more non-Gaussian features, but
has little effect at large scales. The patchy nature of the reionization
process roughly doubles the total observed kSZ signal for l~3000-10^4 compared
to non-patchy scenarios with the same total electron-scattering optical depth.Comment: 14 pages, 13 figures (some in color), submitted to Ap
Flower-specific KNOX phenotype in the orchid Dactylorhiza fuchsii
The KNOTTED1-like homeobox (KNOX) genes are best known for maintaining a pluripotent stem-cell population in the shoot apical meristem that underlies indeterminate vegetative growth, allowing plants to adapt their development to suit the prevailing environmental conditions. More recently, the function of the KNOXgene family has been expanded to include additional roles in lateral organ development such as complex leaf morphogenesis, which has come to dominate the KNOX literature. Despite several reports implicating KNOX genes in the development of carpels and floral elaborations such as petal spurs, few authors have investigated the role of KNOX genes in flower development. Evidence is presented here of a flower-specific KNOX function in the development of the elaborate flowers of the orchid Dactylorhiza fuchsii, which have a three-lobed labellum petal with a prominent spur. Using degenerate PCR, four Class I KNOX genes (DfKN1–4) have been isolated, one from each of the four major Class I KNOX subclades and by reverse transcription PCR (RT-PCR), it is demonstrated that DfKNOXtranscripts are detectable in developing floral organs such as the spur-bearing labellum and inferior ovary. Although constitutive expression of the DfKN2 transcript in tobacco produces a wide range of floral abnormalities, including serrated petal margins, extra petal tissue, and fused organs, none of the vegetative phenotypes typical of constitutive KNOX expression were produced. These data are highly suggestive of a role for KNOX expression in floral development that may be especially important in taxa with elaborate flowers
The triennial International Pigment Cell Conference (IPCC)
The International Federation of Pigment Cell Societies (IFPCS) held its XXIII
triennial International Pigment Cell Conference (IPCC) in Denver, Colorado in
August 2017. The goal of the summit was to provide a venue promoting a vibrant
interchange among leading basic and clinical researchers working on
leading-edge aspects of melanocyte biology and disease. The philosophy of the
meeting, entitled Breakthroughs in Pigment Cell and Melanoma Research, was to
deliver a comprehensive program in an inclusive environment fostering
scientific exchange and building new academic bridges. This document provides
an outlook on the history, accomplishments, and sustainability of the pigment
cell and melanoma research community. Shared progress in the understanding of
cellular homeostasis of pigment cells but also clinical successes and hurdles
in the treatment of melanoma and dermatological disorders continue to drive
future research activities. A sustainable direction of the societies creates an
international forum identifying key areas of imminent needs in laboratory
research and clinical care and ensures the future of this vibrant, diverse and
unique research community at the same time. Important advances showcase wealth
and breadth of the field in melanocyte and melanoma research and include
emerging frontiers in melanoma immunotherapy, medical and surgical oncology,
dermatology, vitiligo, albinism, genomics and systems biology, precision
bench-to-bedside approaches, epidemiology, pigment biophysics and chemistry,
and evolution. This report recapitulates highlights of the federate meeting
agenda designed to advance clinical and basic research frontiers from melanoma
and dermatological sciences followed by a historical perspective of the
associated societies and conferences
Redshifts and Velocity Dispersions of Galaxy Clusters in the Horologium-Reticulum Supercluster
We present 118 new optical redshifts for galaxies in 12 clusters in the
Horologium-Reticulum supercluster (HRS) of galaxies. For 76 galaxies, the data
were obtained with the Dual Beam Spectrograph on the 2.3m telescope of the
Australian National University at Siding Spring Observatory. After combining 42
previously unpublished redshifts with our new sample, we determine mean
redshifts and velocity dispersions for 13 clusters, in which previous
observational data were sparse. In six of the 13 clusters, the newly determined
mean redshifts differ by more than 750 km/s from the published values. In the
case of three clusters, A3047, A3109, and A3120, the redshift data indicate the
presence of multiple components along the line of sight. The new cluster
redshifts, when combined with other reliable mean redshifts for clusters in the
HRS, are found to be distinctly bi-modal. Furthermore, the two redshift
components are consistent with the bi-modal redshift distribution found for the
inter-cluster galaxies in the HRS by Fleenor et al. (2005).Comment: 13 pages, 3 figures, Accepted to A
A Framework for Dimensioning VDL-2 Air-Ground Networks
This paper describes a framework developed at MITRE for dimensioning a Very High Frequency (VHF) Digital Link Mode 2 (VDL-2) Air-to-Ground network. This framework was developed to support the FAA's Data Communications (Data Comm) program by providing estimates of expected capacity required for the air-ground network services that will support Controller-Pilot-Data-Link Communications (CPDLC), as well as the spectrum needed to operate the system at required levels of performance. The Data Comm program is part of the FAA's NextGen initiative to implement advanced communication capabilities in the National Airspace System (NAS). The first component of the framework is the radio-frequency (RF) coverage design for the network ground stations. Then we proceed to describe the approach used to assess the aircraft geographical distribution and the data traffic demand expected in the network. The next step is the resource allocation utilizing optimization algorithms developed in MITRE's Spectrum ProspectorTM tool to propose frequency assignment solutions, and a NASA-developed VDL-2 tool to perform simulations and determine whether a proposed plan meets the desired performance requirements. The framework presented is capable of providing quantitative estimates of multiple variables related to the air-ground network, in order to satisfy established coverage, capacity and latency performance requirements. Outputs include: coverage provided at different altitudes; data capacity required in the network, aggregated or on a per ground station basis; spectrum (pool of frequencies) needed for the system to meet a target performance; optimized frequency plan for a given scenario; expected performance given spectrum available; and, estimates of throughput distributions for a given scenario. We conclude with a discussion aimed at providing insight into the tradeoffs and challenges identified with respect to radio resource management for VDL-2 air-ground networks
Tentative co-orbital submillimeter emission within the Lagrangian region L5 of the protoplanet PDS 70 b
Context: High-spatial resolution Atacama Large Millimeter/submillimeter Array
(ALMA) data have revealed a plethora of substructures in protoplanetary disks.
Some of those features are thought to trace the formation of embedded planets.
One example is the gas and dust that accumulated in the co-orbital Lagrangian
regions /, which were tentatively detected in recent years and might
be the pristine material for the formation of Trojan bodies. Aims: This work is
part of the TROY project, whose ultimate goal is to find robust evidence of
exotrojan bodies and study their implications in the exoplanet field. Here, we
focus on the early stages of the formation of these bodies by inspecting the
iconic system PDS 70, the only confirmed planetary system in formation.
Methods: We reanalyzed archival high-angular resolution Band 7 ALMA
observations from PDS 70 by doing an independent imaging process to look for
emission in the Lagrangian regions of the two detected gas giant protoplanets,
PDS 70 b and c. We then projected the orbital paths and visually inspected
emission features at the regions around the / locations as defined by
60 in azimuth from the planet position. Results: We found
emission at a 4- level (6- when correcting from a
cleaning effect) at the position of the region of PDS 70 b. This
emission corresponds to a dust mass in a range of 0.03- 2 M, which
potentially accumulated in this gravitational well. Conclusions: The tentative
detection of the co-orbital dust trap that we report requires additional
observations to be confirmed. We predict that we could detect the co-orbital
motion of PDS 70 b and the dust presumably associated with by observing
again with the same sensitivity and angular resolution as early as February
2026.Comment: 8 pages, 5 figures, 2 tables. Published in Astronomy & Astrophysic
