Uniform Basis: Who Can Claim Depreciation After Death And How Much?, Neil E. Harl Dec 2014

Uniform Basis: Who Can Claim Depreciation After Death And How Much?, Neil E. Harl

Agricultural Law Digest

Leaving property at death to the surviving spouse for life (a legal life estate or a life estate in trust) with a remainder interest to a child or children has been a fairly common strategy and continues to be used even with the larger applicable exclusion amount1 and “portability” (which allows the surviving spouse to use the unused applicable exclusion amount at the death of the first spouse to die if the requirements are met).2 One important issue is how is the income tax basis handled under the “uniform basis” rules? What happens if the holder of the life ...

Rationality, Legitimacy, & The Law, Daniel Z. Epstein Nov 2014

Rationality, Legitimacy, & The Law, Daniel Z. Epstein

Washington University Jurisprudence Review

American legal realism was committed to examining legal reasoning in terms of the actual experiences of judges. Because the realist project sought to use social science tools to examine human nature, the contemporary rise of cognitive neuroscience provides an occasion for re-examining legal realism’s foundational critique of the law. Realism’s attempt to examine “the actual facts of judicial behavior” and to pursue a “scientific description and prediction of judicial behavior” appears to be a suitable vehicle for considering the relevance of cognitive neuroscience for legal theory. Cognitive neuroscience has provided convincing evidence for rejecting the traditional bifurcation between ...

Another Slant To Co-Ownership Discounts, Neil E. Harl Nov 2014

Another Slant To Co-Ownership Discounts, Neil E. Harl

Agricultural Law Digest

A decision by the Fifth Circuit Court of Appeals in 2014, Elkins v. Commissioner1 involving co-ownership of art collections has added another chapter to the saga of coownership discounts.2 Although other courts have allowed discounts for the costs of partition and sale, the courts generally have been reluctant to allow more than a token discount for a fractional interest itself in art works.3 The Elkins case4 allowed a 44.75 percent discount for undivided interests in works of art and a 10 percent discount for restrictions on transferability.5 An earlier Ninth Circuit case approved a token five ...


Hairy Stalagmites, A New Biogenic Root Speleothem From Botswana, Gerhard C. Du Preez, Paolo Forti, Gerhard Jacobs, Anine Jordaan, Louwrens Tiedt Nov 2014

Hairy Stalagmites, A New Biogenic Root Speleothem From Botswana, Gerhard C. Du Preez, Paolo Forti, Gerhard Jacobs, Anine Jordaan, Louwrens Tiedt

International Journal of Speleology

Ngamiland in northwestern Botswana hosts the Gcwihaba Caves which present unique subterranean environments and host speleothems never before recorded. Cave atmospheric conditions can be extreme with temperatures as high as 28°C and relative humidity nearing 99.9%. Within Dimapo and Diviner’s Caves peculiar root speleothems that we named ‘Hairy Stalagmites’ were found. These stalagmites are closely associated with the roots of Namaqua fig (Ficus cordata) trees that enter the cave environment in search of water. Pieces of broken stalagmites were sampled from Dimapo Cave for further investigations. Stereo and electron microscopy revealed that the Hairy Stalagmites consist of ...


Parental Involvement During Adolescence And Contraceptive Use In College, Caroline Payne Purvis, Rosemary V. Barnett, Larry Forthun Nov 2014

Parental Involvement During Adolescence And Contraceptive Use In College, Caroline Payne Purvis, Rosemary V. Barnett, Larry Forthun

Journal of Adolescent and Family Health

The current study aimed to explore the relationships between parental involvement during adolescence on sexual behaviors among college students. Research has shown that parental involvement decreases as students move from high school to college, but the impact that parents had on their students while in high school continues into college. It is important to determine if one factor relating to the number of sexual partners, sexual activity, and contraceptive use is parental involvement during adolescence. After approval from the Institutional Review Board (IRB), an online survey using Survey Monkey was administered to a convenience sample of undergraduate students in a ...


University Professors’ Perceptions About The Impact Of Integrating Google Applications On Students’ Communication And Collaboration Skills, Jacqueline L. Cahill Nov 2014

University Professors’ Perceptions About The Impact Of Integrating Google Applications On Students’ Communication And Collaboration Skills, Jacqueline L. Cahill

Journal of Research Initiatives

A qualitative research study was conducted and data were collected by interviewing university professors on their perceptions about the impact of integrating Google Apps, as a means of classroom instructional delivery, on students’ communication and collaboration skills. The participants consisted of eight university professors from a major university, who integrate, or had previously integrated at least two Google Apps Education Edition collaborative tools into their instructional strategies. The result of this study has the potential to benefit universities that are debating on whether utilizing teaching collaborative technology skills, as an instruction tool, would engage students and enhance their communication skills ...


The Reduction Of Metabolic Cost While Using Handrail Support During Inclined Treadmill Walking Is Dependent On The Handrail-Use Instruction, Cory Hofmann, Connor Dougherty, Hagop Abkarian, Michele Fox, Paul Juris Nov 2014

The Reduction Of Metabolic Cost While Using Handrail Support During Inclined Treadmill Walking Is Dependent On The Handrail-Use Instruction, Cory Hofmann, Connor Dougherty, Hagop Abkarian, Michele Fox, Paul Juris

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 339-345, 2014. Inclined treadmill walking is a commonly performed activity to increase cardiovascular health. Handrail support on a treadmill provides an individual the opportunity to change their posture with respect to the walking surface. Differences in metabolic cost during inclined walking due to postural changes with handrail use are unknown. To test the hypothesis that metabolic cost will differ depending on how handrail support is used, respiratory gas analysis was performed during inclined walking in 13 healthy subjects. Energy expenditure was quantified while each subject walked in four conditions: 5% incline unsupported, 10 ...


When A Small Foundation Becomes A “Private Foundation”, Neil E. Harl Nov 2014

When A Small Foundation Becomes A “Private Foundation”, Neil E. Harl

Agricultural Law Digest

With the increase in wealth in rural areas in recent years has come the growth in non-profit organizations, often organized as family entities to assist in perpetuating some feature of rural life. The focus may be on the local schools; colleges or universities, often in the form of scholarships; the local church; soil conservation; the local community itself or any one of a number of other family concerns. Most are organized as corporations under state law and have sought (and usually obtained) federal status to operate “. . . for religious, charitable, scientific, testing for public safety, literary or educational purposes. . . “ along with ...

Harmonic Language Arts: Music Inclusion In The Secondary English Language Arts Classroom, Julieanne Sthay Nov 2014

Harmonic Language Arts: Music Inclusion In The Secondary English Language Arts Classroom, Julieanne Sthay

CrissCross

Students are required to take four years of high school English, and the mandatory nature of English coupled with a scripted curriculum negatively impact student interest and motivation. English teachers who incorporate music into their academic teaching are finding music can improve student engagement, motivation, and learning (Goering & Burenheide, 2010). In this qualitative self study of student teaching, I explored questions including whether the addition of music is worthwhile in the English classroom, how it can be done, and what the benefits and drawbacks of doing so are. Based upon field notes, lesson plans, student feedback and research, I found ...


Experiencing The Ineffable, Joseph O'Brien Nov 2014

Experiencing The Ineffable, Joseph O'Brien

CrissCross

I can recall the first time I learned to take a fish off the hook after catching it. My grandfather and I were fishing in a river near my home in Connecticut, the sun shone off the yellow of a pumpkinseed sunfish's belly. After removing it from the hook, I put it in a five-gallon pail of water. Despite the clarity of the things I do recall, there are those elements of this memory that remain wholly inaccessible to me. I cannot remember whether it was late spring or early autumn, what color my rod was, or if there ...


Carving The Perfect Citizen: The Adventures Of Soviet Pinocchio In Text And On Screen, Rachel Branson Nov 2014

Carving The Perfect Citizen: The Adventures Of Soviet Pinocchio In Text And On Screen, Rachel Branson

CrissCross

In 1936, Alexei Tolstoy’s The Golden Key, or The Adventures of Buratino was published, heralding the use of children’s literature and fairy tale structure as an ideological and transformative tool for children in the Soviet Union. The Adventures of Buratino, framed by Alexei Tolstoy’s alleged recreation from memory of Carlo Collodi’sThe Adventures of Pinocchio (1883), was a Soviet fairy tale, portraying Buratino as a hero for his fellow puppets in helping to free them from the corrupt and oppressive power of Karabas Barabas, the owner of the puppet theater. While Barabas serves as an embodiment ...


Lactate Threshold Comparison In Anaerobic Vs. Aerobic Athletes And Untrained Subjects, Matt Green, Jared Hornsby, Robert Pritchett, Kelley Pritchett Nov 2014

Lactate Threshold Comparison In Anaerobic Vs. Aerobic Athletes And Untrained Subjects, Matt Green, Jared Hornsby, Robert Pritchett, Kelley Pritchett

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 329-338, 2014. This study compared VO2 max, lactate threshold (LT) and VO2 at LT (VO2LT) among aerobic athletes (ARA) (n=10), anaerobic athletes (ANA) (n=9) and untrained participants (UTS) (n=7). From a treadmill test to exhaustion, VO2 max and LT (4 mmol·L-1 blood lactate concentration) were assessed. Analysis of variance showed VO2 max (ml·kg-1·min-1) was significantly greater for ARA (67.6 ± 9.4) than ANA (53.4 ± 6.4) and UTS (44.9 + 6.9), with ANA significantly greater than ...

New Flea (Siphonaptera) Record For Heermann's Kangaroo Rat (Dipodomys Heermanni), San Luis Obispo County, California, Howard O. Clark Jr., Helen K. Pigage

Western North American Naturalist

Three Heermann’s kangaroo rats (Dipodomys heermanni), from San Luis Obispo County, California, were examined for ectoparasites. Two species of flea were found,Meringis californicus and Hoplopsyllus anomalus. Occurrence of these two species onDipodomys heermanni has not been reported before and represents new host records.


Demographic Monitoring And Population Viability Analysis Of Two Rare Beardtongues From The Uinta Basin, Rebecca M. Mccaffery, Rita Reisor, Kathryn Irvine, Jessi Brunson Nov 2014

Demographic Monitoring And Population Viability Analysis Of Two Rare Beardtongues From The Uinta Basin, Rebecca M. Mccaffery, Rita Reisor, Kathryn Irvine, Jessi Brunson

Western North American Naturalist

Energy development, in combination with other environmental stressors, poses a persistent threat to rare species endemic to the energy-producing regions of the Western United States. Demographic analyses of monitored populations can provide key information on the natural dynamics of threatened plant and animal populations, and how they might be affected by ongoing and future development. In the Uinta Basin in Utah and Colorado, Graham’s beardtongue (Penstemon grahamii) and White River beardtongue (Penstemon scariosus var. albifluvis) are two rare endemic wildflowers that persist on oil shale habitats heavily impacted by current energy exploration and development, and slated for expanded traditional ...


The Plecoptera And Trichoptera Of The Arctic North Slope Of Alaska, Michael R. Kendrick, Alexander D. Huryn Nov 2014

The Plecoptera And Trichoptera Of The Arctic North Slope Of Alaska, Michael R. Kendrick, Alexander D. Huryn

Western North American Naturalist

The Arctic is currently experiencing changes in climate more rapid than any other biome. This warming trend has resulted in significant abiotic changes to the seasonal patterns of freshwater ecosystems. Thorough inventories of freshwater insect communities are required to provide benchmarks allowing for the detection of range shifts in response to a warming climate. While statewide studies have been conducted for Trichoptera and Plecoptera, species accounts for these orders in Arctic Alaska have received relatively little attention. We surveyed Plecoptera and Trichoptera of Alaska’s Arctic North Slope at a variety of habitat types over an 11 year period. We ...


Influence Of Nonnative And Native Ungulate Biomass And Seasonal Precipitation On The Vegetation Production In A Great Basin Ecosystem, Linda C. Zeigenfuss, Kathryn A. Schoenecker, Jason I. Ransom, Drew A. Ignizio, Tracy Mask Nov 2014

Influence Of Nonnative And Native Ungulate Biomass And Seasonal Precipitation On The Vegetation Production In A Great Basin Ecosystem, Linda C. Zeigenfuss, Kathryn A. Schoenecker, Jason I. Ransom, Drew A. Ignizio, Tracy Mask

Western North American Naturalist

The negative effects of equid grazers in semi-arid ecosystems of the American West has been considered to be disproportionate to the influence of native ungulates in these systems because of their large body size, hoof shape, and short history on the landscape relative to native grazers. Tools which can model the degree of influence of various grazers in an ecosystem and separate these effects from those caused by other variables (climate, anthropomorphic disturbances) can be useful to managers in determining location of non-native grazer impacts and assessing the effect of management actions targeted at different grazer populations. We used remotely ...


Estimating The Ages Of Mountain Sucker Catostomus Platyrhynchus From The Black Hills: Precision, Maturation, And Growth, Jason J. Breeggemann, Cari-Ann Hayer, Jacob Krause, Luke D. Schultz, Katie N. Bertrand, Brian D. S. Graeb Nov 2014

Estimating The Ages Of Mountain Sucker Catostomus Platyrhynchus From The Black Hills: Precision, Maturation, And Growth, Jason J. Breeggemann, Cari-Ann Hayer, Jacob Krause, Luke D. Schultz, Katie N. Bertrand, Brian D. S. Graeb

Western North American Naturalist

Mountain Sucker Catostomus platyrhynchus is considered secure across its range, it has been declining in parts of its range, and is listed as a species of greatest conservation need in South Dakota. To our knowledge, no research has identified which calcified structure yields the most precise age estimates for Mountain Sucker and little is known about Mountain Sucker population dynamics. We compared scales, sectioned fin rays, whole otoliths, and polished otoliths to identify which structure provided the most precise age estimates for Mountain Sucker in the Black Hills of South Dakota. Additionally, we quantified recruitment, growth, age and size at ...


Reproduction And Pollination Of The Endangered Dwarf Bear-Poppy Arctomecon Humilis (Papaveraceae) Across A Quarter Century: Unraveling Of A Pollination Web?, Vincent J. Tepedino, John Mull, Terry L. Griswold, Gerald Bryant Nov 2014

Reproduction And Pollination Of The Endangered Dwarf Bear-Poppy Arctomecon Humilis (Papaveraceae) Across A Quarter Century: Unraveling Of A Pollination Web?, Vincent J. Tepedino, John Mull, Terry L. Griswold, Gerald Bryant

Western North American Naturalist

Arctomecon humilis, a rare gypsophile of the extreme northeastern Mojave Desert, is restricted to a few isolated populations (occurrences) in Washington Co, Utah (USA). At several points in the past quarter century, we have studied the breeding system and reproductive success of this endangered species, recorded its pollinators and tested the feasibility of human-assisted gene flow by conducting reciprocal crosses between two isolated occurrences approximately 4 km apart. We found A. humilis to possess a mixed breeding system in the occurrence studied (Beehive Dome in 1988); some plants exhibited self-compatibility but fruit/flowers and seeds/fruit were significantly lower in ...


Population Genetic Structure Of The Baird's Pocket Gopher, Geomys Breviceps, In Eastern Texas, Sarah R. Welborn, Jessica E. Light Nov 2014

Population Genetic Structure Of The Baird's Pocket Gopher, Geomys Breviceps, In Eastern Texas, Sarah R. Welborn, Jessica E. Light

Western North American Naturalist

The Baird’s pocket gopher (Geomys breviceps) is a solitary, fossorial rodent found throughout areas of Texas, Arkansas, Oklahoma, and Louisiana. These rodents are highly modified morphologically for an underground lifestyle, often resulting in limited vagility and isolated populations. Despite these unique characteristics, little is known about the population genetics of pocket gophers. We used mitochondrial and microsatellite data and performed a series of population genetic analyses to better understand the population structure and gene flow among a series of G. brevicepslocalities. Population genetic analyses supported high levels of gene flow among nearby localities (within 2 km of each ...


Plant Community Changes Following Closure Of Artesian Wells In Great Sand Dunes National Park, Colorado, Sarah J. Garza, Gillian Bowser, Kenneth R. Wilson Nov 2014

Plant Community Changes Following Closure Of Artesian Wells In Great Sand Dunes National Park, Colorado, Sarah J. Garza, Gillian Bowser, Kenneth R. Wilson

Western North American Naturalist

Artificial artesian wells have existed in the San Luis Valley of south central Colorado for over 100 years and are an important source of water for livestock and wildlife. When Great Sand Dunes National Park and Preserve (GRSA) expanded its boundaries in 2000, 10 of these wells were within the new park boundary. In 2010, the National Park Service capped these wells to restore the surrounding habitat to a more natural state, which was severely disturbed from cattle and wildlife trampling. To study changes after well capping, we compared the plant communities in 2011 and 2012 and measured plant cover ...


Home-Range Size And Subadult Dispersal Of Black Bears In The Cascade Range Of Western Oregon, Dave Immell, Dewaine H. Jackson, Margaret C. Boulay Nov 2014

Home-Range Size And Subadult Dispersal Of Black Bears In The Cascade Range Of Western Oregon, Dave Immell, Dewaine H. Jackson, Margaret C. Boulay

Western North American Naturalist

Knowledge of home range size and subadult dispersal activity of North American black bears is essential for understanding the complexity of how bears interact within populations and the environment. During 1993-98, we monitored 96 radiocollared black bears (Ursus americanus) in the Cascade Range of western Oregon to estimate home range and dispersal movements. Composite fixed-kernel home ranges were calculated for 37 bears. Mean home range size differed between sexes (189.7 km2 for males and 33.6 km2 for females); however, there was no difference between subadult and adult male or subadult and adult female mean home range ...


Rediscovered Populations Of The Idaho Point-Headed Grasshopper, Acrolophitus Pulchellus (Bruner), 1890 (Orthoptera: Acrididae), Beth A. Waterbury Nov 2014

Rediscovered Populations Of The Idaho Point-Headed Grasshopper, Acrolophitus Pulchellus (Bruner), 1890 (Orthoptera: Acrididae), Beth A. Waterbury

Western North American Naturalist

The Idaho point-headed grasshopper, Acrolophitus pulchellus, is a rare endemic of the Sinks Drainages of east-central Idaho. Past collections were infrequent and found few specimens. Searches in 1993 failed to find specimens, leading to speculaton that A. pulchellus was extinct. I report rediscovered populations of A. pulchellus based on 55 capture records (10 collected); describe distribution, habitat, morphological, and life history information; and present the first photos of live adult specimens.


First Record Of Leucism In The Genus Peromyscus (Mammalia: Rodentia), Issac Camargo, Evelyn Rios, Cristian Cornejo-Latorre, Sergio Ticul Álvarez-Castañeda Nov 2014

First Record Of Leucism In The Genus Peromyscus (Mammalia: Rodentia), Issac Camargo, Evelyn Rios, Cristian Cornejo-Latorre, Sergio Ticul Álvarez-Castañeda

Western North American Naturalist

Leucism is a partial hypopigmentary congenital disorder previously recorded in several species of mammals. This abnormal coloration is unusual in the wild. In August 2013, in the Baja California State, México, we collected two Peromyscus fraterculus (one female and one male) exhibiting leucism. Leucism has not been reported before ingenus Peromyscus, therefore, we documented the first known record. Leucism is a reflex of low levels of genetic diversity in natural populations. It may increase selective pressure on individuals.
