Assessing statistical significance of periodogram peaks
The least-squares (or Lomb-Scargle) periodogram is a powerful tool which is
used routinely in many branches of astronomy to search for periodicities in
observational data. The problem of assessing statistical significance of
candidate periodicities for different periodograms is considered. Based on
results in extreme value theory, improved analytic estimations of false alarm
probabilities are given. They include an upper limit to the false alarm
probability (or a lower limit to the significance). These estimations are
tested numerically in order to establish regions of their practical
applicability.Comment: 7 pages, 6 figures, 1 table; To be published in MNRA
Price Gouging: Application of Florida\u27s Deceptive and Unfair Trade Practices Act in the Aftermath of Hurricane Andrew
On August 23, 1992, in the wake of Hurricane Andrew, Florida\u27s Governor, Lawton Chiles, issued Executive order 92-222-E making the imposition or demand of an exorbitant or excessive price by any vendor of fuels, foods, medicine or other necessities a violation of Florida\u27s Deceptive and Unfair Trade Practices Act (the Act)
The Child is Mother of the Woman: Parenting and Self-Parenting in Emma and Middlemarch
In order to examine the significance of parent-child relationships vis á vis the growing autonomy of Emma Woodhouse and Dorothea Brooke, we must first look at them as daughters in relation to parents, real or surrogate, ineffectual or influential. Next, to what extent do these two women act as counsellors and parents for siblings and friends, and how does their attitude to that role change? Last, both these novels feature heroines whose husbands or future husbands are much older than they are, and who assume parental roles with them. How does each heroine relate to this father/lover figure? Is he the cause or the catalyst of her maturation?
As I hope to show, the obstacles created by these various relationships ultimately enable our heroines to examine and accept their values and themselves. Each author explores the issue differently, however. Though Austen does not use the language and imagery of parenting, birth, and growth that Eliot does, she communicates her notion of parenting by concentrating on issues such as good judgment and compassion. In the end, they show that each heroine self-sufficiently creates and nurtures a self which is at least a partial realization of her great potential. In effect, she becomes maturely suited to parent as a consequence of becoming her own surrogate parent
The Roles of Architect and Contractor in Construction Management
For the architect and building contractor the most significant aspect of modern commercial construction may not be the design but rather the management, consisting of coordination and administration, of large-scale building projects. Despite the importance of construction management, especially in mammoth and complex projects such as New York\u27s World Trade Center, legislatures have been slow to respond to the needs and practices of the construction industry. Although the skills involved indicate that the role of construction manager is more appropriately assumed by a contractor, the laws of several states provide that only a licensed architect can take responsible charge of construction. Legislatures should recognize that the performance of construction management may include the assumption of some obligations traditionally assigned by law to the exclusive domain of the architect. Moreover, it would appear from a cursory view of actual practices that professionals other than architects are acting in the role of construction manager. If legislatures are concerned with the actual needs and practices of the architectural profession, and their enacting of licensing statutes indicates that such is the case, legislatures should clarify the various licensing statutes to take account of these adjustments in the architect\u27s role in construction

Abundances of Disk Planetary Nebulae in M31 and the Radial Oxygen Gradient
We have obtained spectra of 16 planetary nebulae in the disk of M31 and
determined the abundances of He, N, O, Ne, S and Ar. Here we present the median
abundances and compare them with previous M31 PN disk measurements and with PNe
in the Milky Way. We also derive the radial oxygen gradient in M31, which is
shallower than that in the Milky Way, even accounting for M31's larger disk
scale length.Comment: 2 pages, 1 figure, 1 table, to appear in the proceedings of IAU

Phylogenetics of the Borage Family: Delimiting Boraginales and Assessing Closest Relatives
The placement of Boraginales, and relationships within the family have remained elusive in modern, broad phylogenetic studies. In order to assess the phylogeny of Boraginales, and specifically to test the sister lineage of the order, a data matrix of the chloroplast markers rbcL, ndhF, and trnL-trnF was assembled from GenBank and de novo sequences (representing 132 new GenBank accessions). Phylogenies inferred using Maximum Likelihood and Bayesian frameworks resulted in identical topologies. Tests for alternative topologies were used to assess whether any of the candidates for sister (Solanales, Gentianales, Lamiales, or Vahlia) to Boraginales could be ruled out with this dataset. Gentianales was eliminated as the possible closest relative to Boraginales. Additionally, Shimodaira-Hasegawa tests were used to test topological results within Boraginales: monophyly of Hydrophyllaceae cannot be rejected and paraphyly of Ehretiaceae with respect to the parasitic Lennoaceae is supported. Taxonomic implications are discussed within the context of these phylogenetic results

FABRIC: A National-Scale Programmable Experimental Network Infrastructure
FABRIC is a unique national research infrastructure to enable cutting-edge and exploratory research at-scale in networking, cybersecurity, distributed computing and storage systems, machine learning, and science applications. It is an everywhere-programmable nationwide instrument comprised of novel extensible network elements equipped with large amounts of compute and storage, interconnected by high speed, dedicated optical links. It will connect a number of specialized testbeds for cloud research (NSF Cloud testbeds CloudLab and Chameleon), for research beyond 5G technologies (Platforms for Advanced Wireless Research or PAWR), as well as production high-performance computing facilities and science instruments to create a rich fabric for a wide variety of experimental activities
Some Legislative History and Comments on Ohio\u27s New Criminal Code
Having briefly outlined the history of the formal development of the Act, it is the purpose of this Article to discuss in narrative form the legislative process on certain key provisions which were the subject of much debate and disagreement. These areas of disagreement include murder and felony penalties, especially minimum sentences; capital punishment to conform to the U.S. Supreme Court\u27s Furman decision as well as other changes; parole eligibility for those serving life sentences for a capital offense; early release on parole, also known as shock parole; eligibility for probation; definition of reasonable doubt and jury instructions on reasonable doubt; eventual rejection of seven affirmative defenses which the legislature decided to leave to case law; expanding the definition of rape and creating new sex offenses, such as gross sexual imposition and other changes to sex offense statutes
