A Dubious Exercise of Case Consolidation: \u3cem\u3eCenter For Biological Diversity v. BP America Production Co.\u3c/em\u3e
The explosion of the Deepwater Horizon and the dispersal of millions of gallons of oil into the Gulf of Mexico in 2010 generated a mass of litigation. To organize and manage this complex mass, the U.S. District Court for the Eastern District of Louisiana created “pleading bundles,” which consolidated similar cases, and provided that each bundle must file a single complaint on behalf of the entire group. In Center for Biological Diversity v. BP America Production Co., the U.S. Court of Appeals for the Fifth Circuit affirmed the district court’s dismissal of most of the Center for Biological Diversity’s claims on the grounds of mootness, and further concluded that the district court was within its discretion when placing the Center’s case into a pleading bundle that did not recognize all of the Center’s claims. This Comment argues that the district court’s consolidation technique prejudiced the Center and was inappropriate

A validity study for the kaizen event kick-off survey
This study was conducted to support a research project sponsored by the National Science Foundation (NSF). The purpose of the NSF research project was to determine how to design kaizen events that result in both short term and long term performance improvements. One of the tools developed to evaluate the effectiveness of different kaizen events was a kick-off survey. The use of surveys has been criticized in the past because many researchers do not verify that surveys are valid. The purpose of this investigation was to evaluate the validity of the kaizen event kick-off survey.
The validity of the kaizen event kick-off survey was evaluated with a validity survey. The validity survey was given to university students who then rated how well each of the kick-off survey items measured the underlying kick-off survey constructs. The ratings from the validity survey were analyzed using factor analysis and Wilcoxon signed ranks test. The factor analysis indicated that all of the items except for GDF7, ACC3, and ACC5 demonstrated content validity and construct validity. The Wilcoxon signed ranks test demonstrated content validity for all of the items
High order magnon bound states in the quasi-one-dimensional antiferromagnet -NaMnO
Here we report on the formation of two and three magnon bound states in the
quasi-one-dimensional antiferromagnet -NaMnO, where the single-ion,
uniaxial anisotropy inherent to the Mn ions in this material provides a
binding mechanism capable of stabilizing higher order magnon bound states.
While such states have long remained elusive in studies of antiferromagnetic
chains, neutron scattering data presented here demonstrate that higher order
composite magnons exist, and, specifically, that a weak three-magnon
bound state is detected below the antiferromagnetic ordering transition of
NaMnO. We corroborate our findings with exact numerical simulations of a
one-dimensional Heisenberg chain with easy-axis anisotropy using matrix-product
state techniques, finding a good quantitative agreement with the experiment.
These results establish -NaMnO as a unique platform for exploring
the dynamics of composite magnon states inherent to a classical
antiferromagnetic spin chain with Ising-like single ion anisotropy.Comment: 5 pages, 4 figure

Spectroscopic probe for in vivo measurement of raman signals
An optical probe is disclosed which is suitable for rapidly measuring Raman spectra in vivo. The probe is designed to minimize interfering Raman and fluorescence signals generated within the probe itself. In addition, the probe design is compact, making it particularly suited for use in confined spaces such as body cavities. In one embodiment, the probe is employed to detect tissue abnormalities such as cervical cancers and precancers.Board of Regents, University of Texas Syste
Sexual function in 16- to 21-year-olds in Britain
Purpose:
Concern about young people's sexuality is focused on the need to prevent harmful outcomes such as sexually transmitted infections and unplanned pregnancy. Although the benefit of a broader perspective is recognized, data on other aspects of sexuality, particularly sexual function, are scant. We sought to address this gap by measuring the population prevalence of sexual function problems, help seeking, and avoidance of sex in young people.
Methods:
A cross-sectional stratified probability sample survey (Natsal-3) of 15,162 women and men in Britain (response rate: 57.7%), using computer-assisted self-interviews. Data come from 1875 (71.9%) sexually active, and 517 sexually inactive (18.7%), participants aged 16–21 years. Measures were single items from a validated measure of sexual function (the Natsal-SF).
Results:
Among sexually active 16- to 21-year-old participants, 9.1% of men and 13.4% of women reported a distressing sexual problem lasting 3 months or more in the last year. Most common among men was reaching a climax too quickly (4.5%), and among women was difficulty in reaching climax (6.3%). Just over a third (35.5%) of men and 42.3% of women reporting a problem had sought help, but rarely from professional sources. Among those who had not had sex in the last year, just >10% of young men and women said they had avoided sex because of sexual difficulties.
Conclusions:
Distressing sexual function problems are reported by a sizeable minority of sexually active young people. Education is required, and counseling should be available, to prevent lack of knowledge, anxiety, and shame progressing into lifelong sexual difficulties
Neural evidence for "intuitive prosecution": The use of mental state information for negative moral verdicts
Moral judgment depends critically on theory of mind (ToM), reasoning about mental states such as beliefs and intentions. People assign blame for failed attempts to harm and offer forgiveness in the case of accidents. Here we use fMRI to investigate the role of ToM in moral judgment of harmful vs. helpful actions. Is ToM deployed differently for judgments of blame vs. praise? Participants evaluated agents who produced a harmful, helpful, or neutral outcome, based on a harmful, helpful, or neutral intention; participants made blame and praise judgments. In the right temporo-parietal junction (right TPJ), and, to a lesser extent, the left TPJ and medial prefrontal cortex, the neural response reflected an interaction between belief and outcome factors, for both blame and praise judgments: The response in these regions was highest when participants delivered a negative moral judgment, i.e., assigned blame or withheld praise, based solely on the agent's intent (attempted harm, accidental help). These results show enhanced attention to mental states for negative moral verdicts based exclusively on mental state information.Athinoula A.

The Rotavirus Enterotoxin NSP4 Directly Interacts with the Caveolar Structural Protein Caveolin-1
Rotavirus nonstructural protein 4 (NSP4) is known to function as an intracellular receptor at the endoplasmic reticulum (ER) critical to viral morphogenesis and is the first characterized viral enterotoxin. Exogenously added NSP4 induces diarrhea in rodent pups and stimulates secretory chloride currents across intestinal segments as measured in Ussing chambers. Circular dichroism studies further reveal that intact NSP4 and the enterotoxic peptide (NSP4114-135) that is located within the extended, C-terminal amphipathic helix preferentially interact with caveola-like model membranes. We now show colocalization of NSP4 and caveolin-1 in NSP4-transfected and rotavirus-infected mammalian cells in reticular structures surrounding the nucleus (likely ER), in the cytosol, and at the cell periphery by laser scanning confocal microscopy. A direct interaction between NSP4 residues 112 to 140 and caveolin-1 was determined by the Pro-Quest yeast two-hybrid system with full-length NSP4 and seven overlapping deletion mutants as bait, caveolin-1 as prey, and vice versa. Coimmunoprecipitation of NSP4-caveolin-1 complexes from rotavirus-infected mammalian cells demonstrated that the interaction occurs during viral infection. Finally, binding of caveolin-1 from mammalian cell lysates to Sepharose-bound, NSP4-specific synthetic peptides confirmed the yeast two-hybrid data and further delineated the binding domain to amino acids 114 to 135. We propose that the association of NSP4 and caveolin-1 contributes to NSP4 intracellular trafficking from the ER to the cell surface and speculate that exogenously added NSP4 stimulates signaling molecules located in caveola microdomains
