Tributes to Family Law Scholars Who Helped Us Find Our Path

At some point after the virus struck, I had the idea that it would be appropriate and interesting to ask a number of experienced family law teachers to write a tribute about a more senior family law scholar whose work inspired them when they were beginning their careers. I mentioned this idea to some other long-term members of the professoriate, and they agreed that this could be a good project. So I reached out to some colleagues and asked them to participate. Many agreed to join the team. Some suggested other potential contributors, and some of these suggested faculty members also agreed to submit a tribute. The authors have written about a diverse group of distinguished scholars in the area of family law. We have included 12 scholars who have contributed substantially to the field, and they have also influenced those who have written about them here. The honored scholars and the tribute authors are as follows (organized alphabetically by the honoree): Homer H. Clark Jr. (1918-2015), by Ann Laquer Estin Peggy Cooper Davis, by Melissa Murray Mary Ann Glendon, by June Carbone Herma Hill Kay (1934-2017), by Barbara A. Atwood Robert Levy, by Paul M. Kurtz Marygold (Margo) Shire Melli (1926-2018), by J. Thomas Oldham & Bruce M. Smyth Martha Minow, by Brian H. Bix Robert Mnookin, by Elizabeth S. Scott Twila Perry, by R.A. Lenhardt Dorothy E. Roberts, by Jessica Dixon Weaver Carol Sanger, by Solangel Maldonado Barbara Bennett Woodhouse, by Sacha M. Coupet Each colleague who participated in this project chose the scholar whose work he or she would celebrate. So, the list of those honored here is subjective and, to a certain extent, serendipitous. This Article is part of a Family Law Quarterly issue that also honors other pioneering contributors to the family law field. We hope to make this a continuing project and to have future opportunities to recognize the many scholars who have had a profound impact on their students--and on all of us--in addition to having an important impact on the development of the law. I trust the reader will find these tributes of interest

What is the best portable method of purifying water to prevent infectious disease?

There isn't a single best method, but there are 5 that adequately purify water according to Environmental Protection Agency (EPA) standards. These include 1) boiling for 1 minute if below 2000 m (6562 feet) and 3 minutes if above, 2) chlorine dioxide tablets, 3) MIOX purifier, 4) ultraviolet light (SteriPEN ), and 5) portable filtration with a absolute pore size <1 micrometer combined with halogenation or charcoal filtration (strength of recommendation [SOR ]: C, based on expert opinion and microbiological testing). Halogenation alone (ie, chlorine and iodine) is not effective against Cryptosporidium (SOR : C, based on microbiological testing)

Recent Expansion of Spiranthes cernua (Orchidaceae) into Northern Ontario due to Climate Change?

The expansion northward since 1980 of the native orchid Nodding Ladies'-tresses (Spiranthes cernua) in Ontario is described and assessed with respect to the possibility of the expansion being a recent response to climate change. Based on evidence of the extent of the orchid's distribution from prior botanical surveys, it is considered to be a recent arrival in a previously unoccupied area of northern Ontario. Second-order polynomial regression revealed a significant increase in mean yearly temperature of 1 Celsius degree in parts of northern Ontario since 1980. Based on close association with limits of yearly temperature, this is considered sufficient to explain the expansion, and the individual extensions of range fit well into the anticipated newly available territory. Based on a consideration of the location of extensions with respect to plant hardiness zones, the landscape that has become available since 1980 is 160 000 km2, in a band approximately 200 km wide across the southern part of northern Ontario. Assuming further temperature increases, this band is expected to expand to a width of approximately 300 km by 2040, providing 360 000 km2 of newly available landscape over six decades. Spiranthes cernua produces thousands of seeds per flower by adventitious embryony, allowing single individuals to establish populations through long-distance wind dispersal with no reliance on pollination. Spiranthes cernua is therefore well adapted to quickly colonize new territory that becomes available through climate warming

Hairy St. John’s-wort (Hypericum hirsutum L.) in the Toronto Area, New to North America

Hairy St. John’s-wort (Hypericum hirsutum L.) is newly reported for Canada and North America based on two collections from the Toronto, Ontario, area. This perennial Eurasian herb has a large natural range from western Europe to western China. It grows in moist successional, edge, and meadow habitats. It should be looked for in such habitats elsewhere in eastern North America

Optical attenuation mechanism upgrades, MOBLAS, and TLRS systems

This poster presentation describes the Optical Attenuation Mechanism (OAM) Upgrades to the MOBLAS and TLRS Crustal Dynamics Satellite Laser Ranging (CDSLR) systems. The upgrades were for the purposes of preparing these systems to laser range to the TOPEX/POSEIDON spacecraft when it will be launched in the summer of 1992. The OAM permits the laser receiver to operate over the expected large signal dynamic range from TOPEX/POSEIDON and it reduces the number of pre- and post-calibrations for each satellite during multi-satellite tracking operations. It further simplifies the calibration bias corrections that had been made due to the pass-to-pass variation of the photomultiplier supply voltage and the transmit filter glass thickness. The upgrade incorporated improvements to the optical alignment capability of each CDSLR system through the addition of a CCD camera into the MOBLAS receive telescope and an alignment telescope onto the TLRS optical table. The OAM is stepper motor and microprocessor based; and the system can be controlled either manually by a control switch panel or computer controlled via an EIA RS-232C serial interface. The OAM has a neutral density (ND) range of 0.0 to 4.0 and the positioning is absolute referenced in steps of 0.1 ND. Both the fixed transmit filter and the daylight filter are solenoid actuated with digital inputs and outputs to and from the OAM microprocessor. During automated operation, the operator has the option to overide the remote control and control the OAM system via a local control switch panel

Release of dissolved organic carbon from seagrass wrack and its implications for trophic connectivity

ABSTRACT: The export of old leaves and stems (wrack) from seagrass meadows provides a mechanism for trophic connectivity among coastal ecosystems. As little of this wrack is consumed by mesograzers, leached dissolved organic carbon (DOC) may determine the importance of wrack as a trophic subsidy. However, few studies have examined the effect of seagrass type or age on the release of DOC or its bioavailability. We examined the amount and composition of DOC released from different wrack: Posidonia sinuosa, Amphibolis antarctica and the alga Laurencia sp. We then examined the effect of age on DOC leaching from P. sinuosa wrack. The bioavailability of the DOC was also assessed using a bacterial bioassay. The rate of DOC leaching from P. sinuosa leaves decreased exponentially with time. According to that exponential model, ~50% of the total DOC release occurred in the first 14 d and it would require a further 2.94 yr to release the same amount again. Fresh algae Laurencia sp. leached the greatest amount of DOC in the first 16 h (6.7 g kg-1 fresh weight (FW) wrack), followed by fresh P. sinuosa leaves (1.7 g kg-1 FW), A. antarctica leaves (1.1 g kg-1) and stems (0.6 g kg-1), 4 wk old P. sinuosa (67 g kg-1) and fine detritus (74 g kg-1). In all cases, the composition of the DOC was similar and dominated by the hydrophilic component (in P. sinuosa, predominantly sugars and amino acids). Leachates from all fresh wrack supported bacterial growth over 24 h. Leachate from older wrack either failed to support bacterial growth or only supported it for a limited time. Given the exponential decay in DOC release rate, the interacting timescales of transport and leaching will affect the value of wrack as a vector for trophic subsidies

Myth-busting the provider-user relationship for digital sequence information.

[EN] BACKGROUND: The United Nations Convention on Biological Diversity (CBD) formally recognized the sovereign rights of nations over their biological diversity. Implicit within the treaty is the idea that mega-biodiverse countries will provide genetic resources and grant access to them and scientists in high-income countries will use these resources and share back benefits. However, little research has been conducted on how this framework is reflected in real-life scientific practice. RESULT: Currently, parties to the CBD are debating whether digital sequence information (DSI) should be regulated under a new benefit-sharing framework. At this critical time point in the upcoming international negotiations, we test the fundamental hypothesis of provision and use of DSI by looking at the global patterns of access and use in scientific publications. CONCLUSION: Our data reject the provider-user relationship and suggest a far more complex information flow for DSI. Therefore, any new policy decisions on DSI should be aware of the high level of use of DSI across low- and middle-income countries and seek to preserve open access to this crucial common good.This publication was made possible by the research project WiLDSI (Wissenschaftliche Lösungsansätze für Digitale Sequenzinformation) funded by the German Federal Ministry of Education and Research (BMBF) under funding code 031B0862

Investigation of Current Spike Phenomena During Heavy Ion Irradiation of NAND Flash Memories

A series of heavy ion and laser irradiations were performed to investigate previously reported current spikes in flash memories. High current events were observed, however, none matches the previously reported spikes. Plausible mechanisms are discussed

Conditional random slope: A new approach for estimating individual child growth velocity in epidemiological research

Objectives: Conditioning child growth measures on baseline accounts for regression to the mean (RTM). Here, we present the “conditional random slope” (CRS) model, based on a linear-mixed effects model that incorporates a baseline-time interaction term that can accommodate multiple data points for a child while also directly accounting for RTM.Methods: In two birth cohorts, we applied five approaches to estimate child growth velocities from 0 to 12 months to assess the effect of increasing data density (number of measures per child) on the magnitude of RTM of unconditional estimates, and the correlation and concordance between the CRS and four alternative metrics. Further, we demonstrated the differential effect of the choice of velocity metric on the magnitude of the association between infant growth and stunting at 2 years.Results: RTM was minimally attenuated by increasing data density for unconditional growth modeling approaches. CRS and classical conditional models gave nearly identical estimates with two measures per child. Compared to the CRS estimates, unconditional metrics had moderate correlation (r 5 0.65–0.91), but poor agreement in the classification of infants with relatively slow growth (kappa 5 0.38–0.78). Estimates of the velocity-stunting association were the same for CRS and classical conditional models but differed substantially between conditional versus unconditional metrics.Conclusion: The CRS can leverage the flexibility of linear mixed models while addressing RTM in longitudinal analyses
