Infanticide In Chimpanzees: Taphonomic Case Studies From Gombe, Claire A. Kirchhoff, Michael L. Wison, Deus C. Mjungu, Jane Raphael, Shadrack Kamenya, D. Anthony Collins

Biological Sciences Faculty Research and Publications

Objectives

We present a study of skeletal damage to four chimpanzee (Pan troglodytes) infanticide victims from Gombe National Park, Tanzania. Skeletal analysis may provide insight into the adaptive significance of infanticide by examining whether nutritional benefits sufficiently explain infanticidal behavior. The nutritional hypothesis would be supported if bone survivorship rates and skeletal damage patterns are comparable to those of monkey prey. If not, other explanations, such as the resource competition hypothesis, should be considered.

Methods

Taphonomic assessment of two chimpanzee infants included description of breakage and surface modification, data on MNE, %MNE, and bone survivorship. Two additional infants …

Pulsar J1411+2551: A Low-Mass Double Neutron Star System, J. G. Martinez, K. Stovall, P. C.C. Freire, J. S. Deneva, T. M. Tauris, A. Ridolfi, N. Wex, F. A. Jenet, M. A. Mclaughlin, M. Bagchi

Physics and Astronomy Faculty Publications and Presentations

In this work, we report the discovery and characterization of PSR J1411+2551, a new binary pulsar discovered in the Arecibo 327 MHz Drift Pulsar Survey. Our timing observations of the radio pulsar in the system span a period of about 2.5 years. This timing campaign allowed a precise measurement of its spin period (62.4 ms) and its derivative (9.6 ±0.7) ×10 -20 s s -1 ; from these, we derive a characteristic age of >9.1 Gyr and a surface magnetic field strength of <2.6 ×10 9 G. These numbers indicate that this pulsar was mildly recycled by accretion of matter from the progenitor of the companion star. The system has an eccentric (e =0.17) 2.61 day orbit. This eccentricity allows a highly significant measurement of the rate of advance of periastron, . Assuming general relativity accurately describes the orbital motion, this implies a total system mass M =2.538 ±0.022 M o . The minimum companion mass is 0.92 M o and the maximum pulsar mass is 1.62 M o . The large companion mass and the orbital eccentricity suggest that PSR J1411+2551 is a double neutron star system; the lightest known to date including the DNS merger GW170817. Furthermore, the relatively low orbital eccentricity and small proper motion limits suggest that the second supernova had a relatively small associated kick; this and the low system mass suggest that it was an ultra-stripped supernova.

Managing Cattle Market Risk With Lrp Insurance, Jay Parsons

Cornhusker Economics

Price and market uncertainties pose a significant risk to cattle producers with a substantial amount of money invested in breeding livestock, land, and other infrastructure. Price protection through the Chicago Mercantile Exchange (CME) futures contracts and options can be used to help mitigate this risk but, in the case of futures contracts, they can also introduce financial burdens in the form of margin calls. Furthermore, many medium to small-scale producers prefer not to get involved with trading futures and options contracts.

Arts & Sciences Articles

On 2017 June 8 at 02:01:16.49 UTC, a gravitational-wave (GW) signal from the merger of two stellar-mass black holes was observed by the two Advanced Laser Interferometer Gravitational-Wave Observatory detectors with a network signal-to-noise ratio of. 13. This system is the lightest black hole binary so far observed, with component masses of 12(2)(+7) M-circle dot and 7(2)(+2) M-circle dot (90% credible intervals). These lie in the range of measured black hole masses in low-mass X-ray binaries, thus allowing us to compare black holes detected through GWs with electromagnetic observations. The source's luminosity distance is 340(-140)(+140) Mpc, corresponding to redshift 0.07(-0.03)(+0.03). …

Two cAMP signaling compartments centering around adenylyl cyclase (AC) exist in human airway smooth muscle (HASM) cells, one containing ß2AR-AC6 and another containing E prostanoid receptors (EPR)-AC2. We hypothesized that different phosphodiesterase (PDE) isozymes selectively regulate cAMP signaling in each compartment. According to RNA-seq data, 18 of 24 PDE genes were expressed in primary HASM cells derived from age- and gender-matched donors with and without asthma. PDE8A was the third most abundant of the cAMP-degrading PDE genes, after PDE4A and PDE1A. Knockdown of PDE8A using shRNA evoked 2-fold greater cAMP responses to 1 DM forskolin in the presence of IBMX. …

Pharmacy Faculty Articles and Research

Introduction: Immunosuppression is the mainstay therapy in organ transplantation and autoimmune diseases. The effective clinical application of immunosuppressive agents has suffered from the emergence of systemic immunosuppression and/or individual drug side effects. Nanotechnology approaches may be used to modify the mentioned shortcomings by enhancing the delivery of immunosuppressants to target cells of the immune system, thus reducing the required dose for function, and/or reducing drug distribution to non-target tissues.

Areas covered: We provide an overview on the development of nanotechnology products for the most commonly used immunosuppressive agents. At first, the rationale for the use of nanoparticles as …

Hidalgo-Mihart, Rugieri Juárez-López, Alejandro Jesús De La Cruz, Yaribeth Bravata-De La Cruz, Jesús Iglesias-Hernández, Freddy Pérez-Garduza, Christian A. Delfin-Alfonso, Alberto González-Gallina

Western North American Naturalist

The eastern cottontail rabbit (Sylvilagus floridanus; ECR) is highly adaptable to human activities and widely distributed across the Yucatan Peninsula. However, the eastern part of the peninsula, where the Mexican state of Quintana Roo is located, had only marginal records. Herein, we report the collection of one individual and the observation of 7 different individuals of the ECR in northeastern Quintana Roo. These records increase the range of the species by 66 km into the eastern portion of the Yucatan Peninsula. The absence of previous records of the species—even though the mammalian fauna of the region has been surveyed …

Responsible Pet Ownership: Dog Parks And Demographic Change In Portland, Oregon, Matthew Harris

Dissertations and Theses

Dog parks are the fastest growing type of park in U.S. cities; however, their increasing popularity has been met with increasing criticism of pets in public space. Dogs have shown to be a deep source of neighborhood conflict, and the provision of dog parks, or off-leash areas, is a seemingly intractable controversy for city officials. In 2003, Portland, Oregon established a network of 33 off-leash areas which remains the second largest both in count and per capita in the country. The purpose of my research is to understand the public debate over off leash dogs during the establishment of Portland's …

The New Tax Law’S Impact On Higher Ed, Aldemaro Romero Jr.

Publications and Research

“The power to tax is the power to destroy,” said the fourth Chief Justice of the United States, John Marshall. When one looks at the new tax code produced by the U.S. Congress, we can see how this quote rings a bell of authenticity when it comes to higher education.

Since the latest changes in the U.S. tax code were first proposed, it was clear that higher education was going to be one of the targets of Republicans in Congress. The overall objectives of these changes were to get the money needed to pay for huge tax cuts to benefit …

Living Between Worlds: Arrival And Adjustment Experiences Of The Somali Community In Portland, Oregon, Neil A. Panchmatia

Dissertations and Theses

Since the early 1990s Oregon has witnessed an economic and politically based influx of immigrants and refugees. Most refugees resettled in Oregon initially settled in the greater Portland metro area, and Portland currently ranks eleventh among cities around the country that resettle international refugees. This research focuses on the reception and resettlement experiences of one sub-group of refugees and immigrants: those from Somalia. In the Portland area, Somalis are a largely marginalized social group. They live on the peripheries of society and are often segregated (physically as well as culturally) in what is historically a racially and culturally homogenous state. …
