Two Films, One Law: An Analysis of Social Deviance in Gender, Family, or the Home (Etudes 7)

Section I of this paper analyzes the Court’s obscenity test, and also considers how the expansion of privacy rights since 1973, when the Court developed the current obscenity test, has reframed questions regarding internet-based pornography. Section II addresses the role of shock art in society and questions whether sexual shock art should be protected speech under the Court’s obscenity analysis. Section III develops a new test for obscenity incorporating the harm principle; it would not ask whether the viewer suffered harm, but rather whether the person depicted in the pornography was the victim of a crime during production or suffered severe duress that amounts to sex trafficking.
Phenoxide-Bridged Zinc(II)-Bis(dipicolylamine) Probes for Molecular Imaging of Cell Death

Cell death is involved in many pathological conditions, and there is a need for clinical and preclinical imaging agents that can target and report cell death. One of the best known biomarkers of cell death is exposure of the anionic phospholipid phosphatidylserine (PS) on the surface of dead and dying cells. Synthetic zinc(II)-bis(dipicolylamine) (Zn2BDPA) coordination complexes are known to selectively recognize PS-rich membranes and act as cell death molecular imaging agents. However, there is a need to improve in vivo imaging performance by selectively increasing target affinity and decreasing off-target accumulation. This present study compared the cell death targeting ability of two new deep-red fluorescent probes containing phenoxide-bridged Zn2BDPA complexes. One probe was a bivalent version of the other and associated more strongly with PS-rich liposome membranes. However, the bivalent probe exhibited self-quenching on the membrane surface, so the monovalent version produced brighter micrographs o...
Influence of sex on utilization of feed in turkeys.

Abstract THE fact that Bourbon Red male turkeys weigh on an average approximately 50 percent more than females at seven months of age suggests that possibly the male uses less feed for each pound of weight than the females. The data available at the present time for feed used by chickens and turkeys at different age and weight periods are usually based on flocks carrying both sexes. These data do not show whether there is a difference between the male and female in the amount of feed used per pound of weight. Data collected by Roberts and Carrick (1933) on Barred Plymouth Rock chicks from four to ten weeks of age, show no difference in the feed used for each pound of weight by the different sexes. Data reported by Jull and Titus (1928) on crossbred chicks, from day-old to twenty-four weeks of age with male and females separated, show a . . .
Noncontact diffuse optical assessment of blood flow changes in head and neck free tissue transfer flaps (Conference Presentation)

Head and neck cancer accounts for 3 to 5% of all cancers in the United States. Primary or salvage surgeries are extensive and often lead to major head and neck defects that require complex reconstructions with local, regional, or free tissue transfer flaps. Knowledge of tissue blood flow (BF) changes after free tissue transfer may enable surgeons to predict the failure of flap thrombosis at an early stage. This study used our recently developed noncontact diffuse correlation spectroscopy to monitor dynamic BF changes in free flaps without getting in contact with the targeted tissue. Eight free flaps were elevated in patients with head and neck cancer; one of the flaps failed. Multiple BF measurements probing the transferred tissue were performed during and post the surgical operation. Postoperative BF values were normalized to the intraoperative baselines (assigning '1') for the calculation of relative BF change (rBF). The rBF changes over the seven successful flaps were 1.89 ± 0.15, 2.26 ± 0.13, and 2.43 ± 0.13 (mean ± standard error) respectively on postoperative days 2, 4, and 7. These postoperative values were significantly higher than the intraoperative baseline values (p < 0.001), indicating a gradual recovery of flap vascularity after the tissue transfer. By contrast, rBF changes observed from the unsuccessful flap were 1.14 and 1.34 respectively on postoperative days 2 and 4, indicating a less flow recovery. Measurement of BF recovery after flap anastomosis holds the potential to act early to salvage ischemic flaps.
FGFR Inhibitor Ameliorates Hypophosphatemia and Impaired Engrailed-1/Wnt Signaling in FGF2 High Molecular Weight Isoform Transgenic Mice.

High molecular weight FGF2 transgenic (HMWTg) mouse phenocopies the Hyp mouse, homolog of human X-linked hypophosphatemic rickets with hypophosphatemis, and abnormal FGF23, FGFR, Klotho signaling in kidney. Since abnormal Wnt signaling was reported in Hyp mice we assessed whether Wnt signaling was impaired in HMWTg kidneys and the effect of blocking FGF receptor (FGFR) signaling. Bone mineral density and bone mineral content in female HMWTg mice were significantly reduced. HMWTg mice were gavaged with FGFR inhibitor NVP-BGJ398, or vehicle and were euthanized 24 h post treatment. Serum phosphate was significantly reduced and urine phosphate was significantly increased in HMWTg and was rescued by NVP-BGJ398. Analysis of kidneys revealed a significant reduction in Npt2a mRNA in HMWTg that was significantly increased by NVP-BGJ398. Increased FGFR1, KLOTHO, P-ERK1/2, and decreased NPT2a protein in HMWTg were rescued by NVP-BGJ398. Wnt inhibitor Engrailed-1 mRNA and protein was increased in HMWTg and was decreased by BGJ398. Akt mRNA and protein was decreased in HMWTg and was increased by NVP-BGJ398. The active form of glycogen synthase 3 beta (pGSK3-β) and phosphor-β-catenin were increased in HMWTg and were both decreased by NVP-BGJ398 while decreased active-β-catenin in HMWTg was increased by NVP-BGJ398. We conclude that FGFR blockade rescued hypophosphatemia by regulating FGF and WNT signaling in HMWTg kidneys. J. Cell. Biochem. 117: 1991-2000, 2016. © 2016 Wiley Periodicals, Inc.
Roles in Nursing

Many roles are demanded of nurses. Patients cast nurses into roles that seem necessary for meeting a problem as they view it. Nurses define roles in which they wish to function or that are thought to be desirable performances for a nurse. Society has views on how nurses should function and these conceptions vary in communities and economic groupings. Professional literature promotes pictures that influence nursing; textbooks on professional adjustments traditionally suggest patterns of behavior that indicate nursing roles. The purpose of this chapter is to examine some of the roles that emerge as the nursing process is studied in nurse-patient situations. It suggests principles that govern effective performance in the roles indicated.
Request and fulfillment of postpartum tubal ligation in patients after high-risk pregnancy.

Abstract Objective Female sterilization is one of the most prevalent methods of contraception in the United States. Prior studies have shown that nearly half of postpartum tubal ligation (PPTL) requests go unfulfilled. This study seeks to establish whether obstetric or medical risk status influences patients' request for or subsequent completion of PPTL. Methods This study was a retrospective cohort study of women delivering at a university hospital in 2009–2010 who received prenatal care in the faculty and resident clinics. High-risk status was defined by Society for Maternal-Fetal Medicine guidelines. Documentation of contraceptive plan and administration of contraceptive methods was abstracted from patient records. Subsequent pregnancies through March 1, 2013, were abstracted. Results Of 3063 participants (2048 low risk and 1015 high risk), 231 requested PPTL (7.5%). This was more likely among high-risk patients than low-risk patients (10.0% vs. 6.3%, p Conclusions Though women with high-risk pregnancies were more likely to request PPTL, they were not more likely to complete the procedure. Over one third of high-risk patients' requests were unfulfilled, indicating that significant barriers may remain. Implications Though women with high-risk pregnancies were more likely to request PPTL, they were not more likely to complete the procedure. Providers should consider these procedures urgent, especially in high-risk women, and advocate for their patients' access to this procedure.

Catch ‘Em Being Good:” An Extension Service and State School System Team Up to Promote Positive Outcomes for Youth

This feature article describes a collaboration between the West Virginia University Extension Service and the West Virginia Department of Education to implement the “Responsible Students through School Wide Positive Behavior Supports” program (RS-SWPBS) throughout the state. A case study of Grandview Elementary School in Kanawha County illustrates the benefits that the collaboration brought to local youth. West Virginia Department of Education established the program and brought local schools onboard, while educators from the West Virginia University Extension Service became coaches and led the effort to collect and analyze data. Results included the development of positive behaviors, a decrease in negative behaviors, and the creation of a positive school climate.

Minuscule and cominuscule G/P

In this chapter we present the results for the minuscule and cominuscule G/P. We first present the results of Zelevinsky ([157]) and SankaranVanchinathan ([143, 144]) on small resolutions for Schubert varieties in the minuscule and cominuscule cases. We then present the results of Brion and Polo (cf. [30])on the tangent space to Schubert varieties in the minuscule and cominuscule cases. The results of Lakshmibai—Weyman (cf. [112]) on the irreducible components of the singular loci of Schubert varieties as well as recursive formulae for the multiplicity and the Hilbert polynomial at a singular point are then presented. We have also included two closed formulas due to Kreiman—Lakshmibai ([89]), Rosenthal—Zelevinsky [142] for the multiplicity at a singular point for Schubert varieties in the Grassmannian. We have also included a closed formula for the Hilbert polynomial at a singular point due to Kreiman—Lakshmibai ([89]).

Alzheimer disease makes new blood contacts

In this issue of Blood, Chen and colleagues demonstrate an unanticipated role for the contact system in a murine model of Alzheimer disease (AD). The study bolsters the key role of vascular dysfunction in AD by identifying factor XII (FXII) activation as a new molecular player in AD pathogenesis through mechanisms linked to cerebral fibrin deposition, neuroinflammation, and neuronal damage.
Probing Intermolecular Electron Delocalization in Dimer Radical Anions by Vibrational Spectroscopy

Delocalization of charges is one of the factors controlling charge transport in conjugated molecules. It is considered to play an important role in the performance of a wide range of molecular technologies, including organic solar cells and organic electronics. Dimerization reactions are well-suited as a model to investigate intermolecular spatial delocalization of charges. While dimerization reactions of radical cations are well investigated, studies on radical anions are still scarce. Upon dimerization of radical anions with neutral counterparts, an electron is considered to delocalize over the two molecules. Here, by using time-resolved infrared (TRIR) detection coupled with pulse radiolysis, we show that radical anions of 4-n-hexyl-4′-cyanobiphenyl (6CB) undergo such dimerization reactions, with an electron equally delocalized over the two molecules. We have recently demonstrated that nitrile ν(C≡N) vibrations respond to the degree of electron localization of nitrile-substituted anions: we can quantif...

Design and Initial Results of the Minneapolis Heart Institute TeleHeart Program

Telehealth is an emerging care delivery method that is defined by the use of electronic information and telecommunication technologies to support and promote long-distance clinical health care, patient and professional health-related education, and public health.1 Telehealth is emerging into chronic condition management and settings outside of the acute care hospital.2 The American Heart Association has recognized telehealth as critically important in the future of cardiac care—both to reduce the burden of disease and costs.3 However, there are limited reports of successful implementation of cardiac telehealth programs beyond heart failure monitoring and acute care settings.4 We report the design and initial results of a regional cardiac telehealth system, the Minneapolis Heart Institute (MHI) TeleHeart program. The MHI has 36 clinic outreach sites across Minnesota and Wisconsin, ranging from 8 to 129 miles from the primary hospital, Abbott Northwestern Hospital in Minneapolis, MN (Figure). Many outreach sites have cardiology presence once a week or more, but more distant and rural sites may have on-site cardiologist presence only once or twice a month. These more distant rural sites were experiencing significant delays to cardiology appointments (range, 2.5 to 7.5 weeks) or challenging travel requirements for timely access to outpatient cardiology consultation, particularly in inclement weather. Figure. Minnesota map depicting Minneapolis Heart Institute (MHI) outreach sites and TeleHeart sites (green TH labels). Sites depicted in red are sites with services 5 d/wk. Therefore, the MHI TeleHeart program was designed to improve patient access to care in rural Minnesota by decreasing wait times and travel for specialty cardiovascular care. The program was also designed to enhance regional partnerships and increase cardiovascular subspecialty availability at rural locations. There were several barriers to program development and implementation.
Psychosis in a 22-Year-Old Woman With Narcolepsy After Restarting Sodium Oxybate.

Abstract Sodium oxybate, the sodium salt of γ-hydroxybutyrate (GHB), is a safe and effective treatment for excessive daytime sleepiness and cataplexy in patients with narcolepsy. Other case reports have described acute psychosis in narcoleptic patients shortly after starting or increasing the dose of sodium oxybate. Here we report the case of a 22-year-old woman with narcolepsy who developed acute psychosis after restarting sodium oxybate at a previously well-tolerated dose. This case highlights the importance of titrating sodium oxybate to therapeutic doses, even after short-term discontinuation, in order to avoid psychiatric side effects.
Oxygen Removal from Oxy-Combustion Flue Gas for CO2 Purification via Catalytic Methane Oxidation

Typical allowable O2 concentration in recovered CO2 for certain applications including Enhanced Oil Recovery (EOR) is as low as 100 ppmv. The removal of high content O2 (3–5%) in oxy-combustion flue gas requires additional compression work in the conventional downstream CO2 purification process. RTI hereby proposes to develop a novel technology for flue gas O2 removal based on catalytic oxidation of natural gas. Preliminary catalytic tests were performed over various supported Pd and Pt catalysts under simulated oxy-combustion flue gas conditions, with the addition of a stoichiometric amount of CH4 as a model compound for natural gas. Among the studied catalysts, Pd supported on zeolite H-ZSM-5 showed the highest oxygen conversion at relevant conditions. Compared to Pt catalysts, Pd catalysts generally showed higher oxidation reaction kinetics. The catalytic oxidation activity can be further increased by optimizing reaction gas hourly space velocity (GHSV) and total reaction pressure.
Synthetic and genetically encoded fluorescent neural activity indicators

The ultimate goal of neuroscience is to relate the complex activity of cells and cell-networks to behavior and cognition. This requires tools and techniques to visualize neuronal activity. Fluorescence microscopy is an ideal tool to measure activity of cells in the brain due to the high sensitivity of the technique and the growing portfolio of optical hardware and fluorescent sensors. Here, we give a chemist's perspective on the recent progress of fluorescent activity indicators that enable the measurement of cellular events in the living brain. We discuss advances in both chemical and genetically encoded sensors and look forward to hybrid indicators, which incorporate synthetic organic dyes into genetically encoded protein constructs.
Morbidity and Mortality

Of all demographic factors, morbidity and mortality represent the clearest linkage between demography and health care. In a general way, they represent both the level of need and the extent of the effect of the functioning of the health care system. Morbidity, or the level of sickness and disability within a population, historically has been an area of study for both clinicians and population-oriented scientists such as epidemiologists. In recent years, however, increased activity on the part of demographers has been observed as population researchers apply their methodologies and perspectives in greater detail and with more precision to the study of sickness and death. Mortality refers to the process of death characterizing a population and its study includes the characteristics of those who die as well as what they die from. It is a more traditional focus of demographers, in part because of its direct effect (along with fertility and migration) in bringing about population change.
Translational and Rotational Motion of a Uniaxial Liquid Crystal as Derived Using Hamilton's Principle of Least Action

Abstract The conservative dynamics of the Leslie–Ericksen (LE) Model of a uniaxial liquid crystal are rederived using Hamilton’s Principle of Least Action. This derivation is performed for two purposes: first, to illustrate that variational principles apply to even very complicated fluidic materials, and, secondly, to derive the noncanonical Poisson bracket that generates the conservative dynamics of the LE Model. Although the dissipative mechanisms in the LE Model can be and have been derived through variational formulations (see references below), dissipation is neglected herein to focus on an examination of the origin of rotational motion in this model. This demonstrates that the convective evolution of the microstructure in this model originates solely from the translational and rotational motion of the constituent particles, and not, as is commonly believed, by affine or nonaffine convection and deformation with respect to the local velocity field.

Driving down danger: Using regulatory focus and elaborative approach to reduce intentions to text & drive

Abstract Texting and driving is a growing societal concern, yet few studies have examined motivational determinants and elaborative processing driving this behavior. Thus, we combine regulatory focus theory and two elaborative approaches to information processing (imagining versus considering) to examine the issue of texting and driving. The findings demonstrate that promotion-focused (prevention-focused) individuals have greater intentions to decrease texting and driving when asked to imagine (versus consider) potential outcomes. However, focusing specifically on negative outcomes suppresses the effect of imagining for promotion-focused individuals, whereas a focus on negative outcomes does not significantly change the effect of imagining versus considering for prevention-focused individuals. Further, low (high) cognitive load renders both elaborative approaches equally effective for promotion-focused (prevention-focused) individuals. Finally, negative emotional intensity is identified as the mediator driving these effects. The findings underscore the need to tailor texting and driving advertisements to consumers' motivational and processing frames.
Bacterial Invasion of the Host Cell

In this chapter, the learner will be introduced to the concept that pathogenic bacteria invade host cells. This invasion is not only a mechanism to safeguard bacterial survival, it is often a precursor to disease for the host. The benefits of host cell entry for the invading pathogen are discussed, as is the host response to invasion. The mechanisms pathogenic bacteria use to subvert these host responses are framed in terms of promoting the intracellular survival, and lifestyle, of the bacterium and examples are used from prominent human intracellular bacteria to highlight this interplay. After this chapter, the learner will be able to explain the molecular processes that lead to bacterial uptake and survival, including key steps that might be exploited for therapy.
The Charlie Hebdo Affair in Three African Journalistic Fields

The aim of this chapter is to explore conceptualizations of the different aspects of the Charlie Hebdo Mohammed cartoons affair in the journalistic field of the United States. The chapter explores how the leading American media outlets managed the tension between the human right of freedom of expression and the religious rite of respect for the sacred, using as a case study, deployment of the journalistic right of editorial independence as justification to republish or not to republish the controversial Je Suis Charlie Mohammed cartoon. In effect, the Charlie Hebdo affair exposed a journalistic rift within the American media confraternity. Using their right of editorial independence granted under the First Amendment, some of the major American media outlets and aggregators republished Charlie Hebdo’s Je Suis Charlie Mohammed cartoon, arguing that it was an integral part of the news. However, a smaller number of media outlets, notably, the New York Times and CNN, also decided not to republish any Charlie Hebdo Mohammed cartoons at all in their reporting. The rationale for this decision was fear of the repercussions of reproducing Mohammed cartoons on their international bureaus, and respect for the religious sentiments of their Muslim readers and audiences. Large sections of the American media presented the Charlie Hebdo assassinations as evidence that the journalistic paradigm—and its worldviews, professional norms, routines, independence, and autonomy—was under attack. As such, they assumed a defensive posture, a an attitude of resistance against external threats to the journalistic profession and its independence. A common journalistic resistance tactic is paradigm surveillance. This is a process whereby media outlets check the performance of other media outlets and make a determination whether these other members of the confraternity are doing their part to defend the profession against governmental and private acts of intimidation and censorship.
Obstetric Hemorrhage Outcomes by Intrapartum Risk Stratification at a Single Tertiary Care Center.

Introduction Postpartum hemorrhage is a leading cause of maternal mortality worldwide. Performance of a postpartum hemorrhage risk assessment prior to delivery has been recommended to identify patients at higher risk for hemorrhage to support advanced planning for optimal response. The objective of this quality improvement initiative is to evaluate the transfusion and hemorrhage rates for patients at low, moderate, and high risk for postpartum hemorrhage by utilizing standardized risk assessment. Methods and materials A historic cohort study was performed among women delivering from March 2017 to June 2018 at a single United States military tertiary medical center. A postpartum hemorrhage risk assessment was performed utilizing the California Maternal Quality Care Collaborative toolkit for all patients admitted to Labor and Delivery and when the postpartum hemorrhage risk increased during the intrapartum period. An electronic log was reviewed to determine blood loss volume, change in hematocrit, and transfusion rates in patients at low, moderate, and high risk for postpartum hemorrhage for all deliveries, stratified by delivery type. Results There were 3,377 deliveries during the study period with 145 excluded due to lack of assigned risk category. The high-risk group (12.3% of deliveries) was 4.3 times more likely to receive a blood transfusion, 2.9 times more likely to have a blood loss over 1000 mL, and 2.1 times more likely to have a transfusion or hematocrit drop of 10 points when compared with the low-risk group (69.4% of deliveries). Of those transfused, the majority were classified as low risk as this was the most common assignment. Conclusion Risk stratification can differentiate low from high-risk patients for postpartum hemorrhage and associated transfusion or change in hematocrit. However, the majority of patients who receive a transfusion will be classified as low or moderate risk. Thus, all patients should be monitored closely and treated aggressively to prevent morbidity.
Examining the National Security Implications of Cryptocurrencies

The emergence of block-chain technology in the form known as “cryptocurrency” is an evolution of the global monetary system that is here to stay. The rise of this new variant of distributed ledger technology has been dismissed by some who believe it offers no real value and denigrated by others who believe its prevalence raises national security concerns. Many of these concerns stem from the common misperception that all cryptocurrencies have cryptographic properties which render them anonymous and can be used by terrorists and other undesirables to fund their criminal enterprises. After discussing the basic technical components of blockchain technology, this article distinguishes that, contrary to popular belief, most cryptocurrencies are not what could be classified as “anonymous,” but are instead “pseudonymous.” These pseudonymous cryptocurrencies can actually enhance law enforcement’s ability to track criminal users’ financial activities. It further refines the notion that all cryptocurrencies are the same by noting that some are more anonymous than others, and some are in fact more identifiable than fiat currencies. Instead of resisting cryptocurrencies altogether, this article argues that the United States government should embrace those cryptocurrencies that are pseudonymous and should further study those which are considered anonymous.
The Emergence of Higher-Order Structure in Scientific and Technological Knowledge Networks.

The growth of science and technology is a recombinative process, wherein new discoveries and inventions are built from prior knowledge. Yet relatively little is known about the manner in which scientific and technological knowledge develop and coalesce into larger structures that enable or constrain future breakthroughs. Network science has recently emerged as a framework for measuring the structure and dynamics of knowledge. While helpful, existing approaches struggle to capture the global properties of the underlying networks, leading to conflicting observations about the nature of scientific and technological progress. We bridge this methodological gap using tools from algebraic topology to characterize the higher-order structure of knowledge networks in science and technology across scale. We observe rapid growth in the higher-order structure of knowledge in many scientific and technological fields. This growth is not observable using traditional network measures. We further demonstrate that the emergence of higher-order structure coincides with decline in lower-order structure, and has historically far outpaced the corresponding emergence of higher-order structure in scientific and technological collaboration networks. Up to a point, increases in higher-order structure are associated with better outcomes, as measured by the novelty and impact of papers and patents. However, the nature of science and technology produced under higher-order regimes also appears to be qualitatively different from that produced under lower-order ones, with the former exhibiting greater linguistic abstractness and greater tendencies for building upon prior streams of knowledge.
Hemodynamic intolerance and pericardial effusion associated with high-frequency jet ventilation during pulmonary vein isolation.

Background High-frequency jet ventilation (HFJV) is used during pulmonary vein isolation (PVI) to increase catheter stability and improve outcomes. In prior studies, hemodynamic intolerance to HFJV was rare. Objectives To evaluate the incidence of hemodynamic or respiratory intolerance of HFJV during PVI. Methods Retrospective observational analysis of consecutive patients undergoing PVI performed by 2 operators (PT, JW) at our institution between February 2019 and June 2020 who developed persistent hypotension or abnormal ventilatory parameters in association with HFJV. Results Among 194 PVIs, there were 8 cases (4%) of conversion from HFJV to conventional ventilation, 6 for refractory hypotension and 2 for persistently abnormal gas exchange. In 6 patients, including 5 of the 6 patients with refractory hypotension, a new, small pericardial effusion without tamponade was noted just after HFJV was initiated. In patients with persistent hypotension, a decrease in left ventricular filling and systolic function was frequently noted. Both the hemodynamic changes and effusion resolved almost immediately after discontinuation of HFJV. In 4 patients rechallenged with HFJV, the hypotension and/or effusion recurred quickly and again resolved immediately after return to conventional ventilation. Conclusion HFJV-associated hypotension and systolic dysfunction, often accompanied by a transient pericardial effusion, is present in a small proportion of patients undergoing PVI, and resolves with cessation of HFJV. The mechanism of these changes is unclear and warrants further study.
Chapter 14 Cytochemical Quantitation of Histones

Publisher Summary This chapter discusses the techniques for the cytochemical quantitation of histones. The chapter focuses on the alkaline fast green (AFG) staining technique and its application for quantitative measurements of nuclear histones. A few selected cytochemical methods that are used separately or in conjunction with the AFG technique are described to illustrate the usefulness of such techniques in studies on histone patterns during growth and development. The AFG staining is affected by the type of fixative used. The AFG stainability of nuclear basic proteins depends on the prior removal of DNA by hot TCA or deoxyribonuclease (DNase). Cytochemical methods are valuable tools for studying quantitative and qualitative nuclear histone changes in individual cells during growth and development. Cytochemical methods are limited to detection and analysis of the content of nuclear basic proteins and their overall composition; they do not provide information about chemical modifications and quantitative or qualitative modulations of individual histone fractions that could influence nuclear activity. Therefore, coordinated cytochemical and biochemical studies are necessary for the understanding of the role of histones in nuclear function.
The economic effects of social security: Toward a reconciliation of theory and measurement

Abstract In this paper we argue that actuarial valuation of Social Security benefit streams is theoretically inconsistent with the assumption of pure life cycle motives. Instead, we show that the simple discounted value of future benefits (ignoring the possibility of death) is often a good approximation to the relevant concept of value. This observation motivates a re-examination of existing empirical evidence concerning the economic effects of Social Security. We focus our attention on studies of distributional equity and personal saving behavior. In both cases we argue that the use of simple, rather than actuarial, discounting of survival-contingent income streams produces results that differ dramatically from previous findings. Specifically, estimates based on actuarial valuation may overstate the importance of redistribution between and within generations, and may understate the depressive effect of Social Security on personal wealth accumulation by a factor of three or more.
Clinicopathologic observations in prodromal herpes zoster of the fifth cranial nerve

Abstract It is often difficult to diagnose herpes zoster of the fifth cranial nerve prior to the appearance of the easily recognized cutaneous manifestations. In the case reported here, the disorder first appeared as an oral white patch.
Using the Internet as a Distance Learning Tool in Selected Secondary School Areas

AbstractResearch for the use of computers in education continues to gain momentum. By reviewing the research that has been completed, educators and administrators may find solutions to problems and issues for integrating educational technology into their educational settings. Many tenets of educational technology integration are emerging. Committed leadership, staff development, curriculum integration, technical support, and planning for the future are just a few areas worthy of additional research. The research described here looked at these areas within a unique population of educators and administrators: the United States Army Junior Reserve Officer Training Corps (JROTC) program. The purpose of this research was to analyze the perceptions of Senior Army Instructors (SAIs) toward the use of the Internet as a distance learning tool in meeting the stated desired learning outcomes of the JROTC program. The worldwide study was conducted in the 1998–1999 school year, covering 1,363 high school JROTC units. ...
Personality Dispositions and Political Preferences Across Hard and Easy Issues

A wealth of theoretical and empirical work suggests that conservative orientations in the mass public are meaningfully associated with personality dispositions related to needs for certainty and security. Recent empirical research, however, suggests that (1) associations between these needs and economic conservatism are substantially weaker than associations with conservative identifications and social conservatism, and (2) political sophistication plays an important role in moderating the translation of needs into political preferences within the economic domain. The present article extends this work by offering a theoretical model of the heterogeneous translation of personality dispositions into political preferences across issues and issue domains. We argue that these needs structure preferences directly for highly symbolic issues like those in the social domain, but they structure preferences indirectly through partisanship for difficult issues like those in the economic domain. We test this theory utilizing a national survey experiment in the United States and explore its broader implications for both the literature on the psychological determinants of political ideology and for debates over the “culture war” in the United States.
Studies on polynucleotides. LXXVI. Specificity of transfer RNA for codon recognition as studied by amino acid incorporation.

Abstract The codon recognition of multiple transfer RNA species was tested in amino acid incorporation experiments using ribopolynucleotides of known base sequence as messengers. The results provide convincing evidence for the multiple recognition of codons differing in the third letter by one transfer RNA species and also confirm the transfer RNA recognition patterns previously established by the ribosomal binding technique using trinucleotides. The observed recognition of the codons UUU and UUC by a purified species of yeast phenylalanine transfer RNA of known primary structure (anticodon sequence 2′OMeGAA) constitutes direct evidence for the validity of the codon-anticodon pairing as proposed in the Wobble hypothesis (Crick, 1966).
Hydrodynamic aspects of shark scales

Ridge morphometrices on placoid scales from 12 galeoid shark species were examined in order to evaluate their potential value for frictional drag reduction. The geometry of the shark scales is similar to longitudinal grooved surfaces (riblets) that have been previously shown to give 8 percent skin-friction reduction for turbulent boundary layers. The present study of the shark scales was undertaken to determine if the physical dimensions of the ridges on the shark scales are of the right magnitude to be used by the sharks for drag reduction based on previous riblet work. The results indicate that the ridge heights and spacings are normally maintained between the predicted optimal values proposed for voluntary and burst swimming speeds throughout the individual's ontogeny. Moreover, the species which might be considered to be the faster posses smaller and more closely spaced ridges that based on the riblet work would suggest a greater frictional drag reduction value at the high swimming speeds, as compared to their more sluggish counterparts.
Mandibular symphyseal distraction osteogenesis: diagnosis and treatment planning considerations.

Treatment planning decisions in the transverse dimension have historically been based on the presenting mandibular arch width and form. Distraction osteogenesis (DO), originally developed by Russian orthopedic surgeon Ilizarov, has produced significant results in limb lengthening. Mandibular symphyseal DO was introduced by Guerrero, providing a new paradigm for patients whose treatment alternatives and results were previously limited. Orthodontic and surgical techniques and principles will be shown using completed and current cases. (Angle Orthod 2003;73:3-11.)
Observational Tests to Discern the Topology of Planckian Space-Time

Observational diagnostics are constructed which reflect the underlying topology of Planckian space-time, and are directly related to phenomena on much larger scales. Specific predictions are made for the masses of elementary particles, coupling constants, quark confinement, black hole states, and the cosmological constant. In particular, a mass of 131.6 GeV is found for the Higgs boson. The main presented result is a discrete spectral signature at inverse integer multiples of the zero point frequency $\nu_0=857.3588$ MHz. That is, each photon of frequency $\nu_0m$, for an integer $m$, is paired with an otherwise identical photon $\nu_0/m$, produced by the vacuum, but not vice versa.

Economic Growth Risk: The Role of Foreign Development Assistance and Its Uncertainty

This study is set up to investigate if foreign development assistance and its uncertainty have a joint impact on economic growth risk. Based on the analysis of the average data across 157 countries and territories, the results indicate that, on average, increased foreign development assistance is associated with lower economic growth risk (b = -0.077; p = 0.053), yet increased foreign development assistance uncertainty is significantly linked to higher economic growth risk (b = 0.227; p = 0.000). Foreign development assistance and its uncertainty jointly explain about 11.27% of variation of economic growth risk across countries. The findings provide an important implication for policy debate.
New strings for old Veneziano amplitudes: III. Symplectic treatment

Abstract A d -dimensional rational polytope P is a polytope whose vertices are located at the nodes of Z d lattice. Consider the number | k P ∩ Z d | of points inside the inflated P with coefficient of inflation k ( k = 1 , 2 , 3 , … ) . The Ehrhart polynomial of P counts the number of such lattice points inside the inflated P and (may be) at its faces (including vertices). In Part I [A.L. Kholodenko, New string for old Veneziano amplitudes. I. Analytical treatment, J. Geom. Phys. 55 (2005) 50–74] of our four parts work we noticed that Veneziano amplitude is just the Laplace transform of the generating function (considered as a partition function in the sense of statistical mechanics) for the Ehrhart polynomial for the regular inflated simplex obtained as deformation retract of the Fermat (hyper) surface living in the complex projective space. This observation is sufficient for development of new symplectic (this work) and supersymmetric (Part II) physical models reproducing the Veneziano (and Veneziano-like) amplitudes. General ideas (e.g. those related to the properties of Ehrhart polynomials) are illustrated by simple practical examples (e.g. use of mirror symmetry for explanation of available experimental data on π π scattering, etc.) worked out in some detail. Obtained final results are in formal accord with those earlier obtained by Vergne [M. Vergne, Convex polytopes and quanization of symplectic manifolds, Proc. Natl. Acad. Sci. 93 (1996) 14238–14242].
Bankruptcy Reform and the Housing Crisis

Reforms made to the U.S. Bankruptcy Code in 2005 instituted a new means testing requirement that restricts the discharge of unsecured debt under Chapter 7 to filers with income below their state's median, thereby forcing filers with income above their state's median into a costly Chapter 13 repayment plan. We construct a quantitative equilibrium model of the mortgage and unsecured credit markets to assess the impact of this reform on the severity of the housing crisis during the Great Recession. We find that while this reform increased the relative attractiveness of mortgage default, its impact on the housing market during the crisis was largely mitigated by general equilibrium effects on mortgage lending standards. Allowing bankruptcy judges to reduce mortgage principal for underwater homeowners through a policy of cramdown would have had only a small impact on the mortgage default rate during the crisis.
Civil Leadership in the Academy

Within pluralistic and diverse communities, civility represents a time-honored strategy that allows individuals and groups with little else in common to live together and get along. Opportunities for civic engagement and contribution are often predicated on shared understandings of civil discourse and behavior. Inability to get along can have dire consequences for any community. Establishing a civil climate is a shared responsibility of community members yet some individuals, by virtue of their influence and authority within the community, serve to establish and model behavioral norms and expectations. Civility in the academy, its presence and value, has been questioned and debated in recent years. (See End Note #1) University presidents and other campus leaders recognize civility as a constituent component of effective leadership. Beyond recognition of its importance to effective leadership, there is a need to examine the root sources of incivility, threats to civility, and approaches to establishing and...
Using isotopes of dissolved inorganic carbon species and water to separate sources of recharge in a cave spring, northwestern Arkansas, USA Blowing Spring Cave

Blowing Spring Cave in northwestern Arkansas is representative of cave systems in the karst of the Ozark Plateaus, and stable isotopes of water (δ18O and δ2H) and inorganic carbon (δ13C) were used to quantify soil-water, bedrock-matrix water, and precipitation contributions to cave-spring flow during storm events to understand controls on cave water quality. Water samples from recharge-zone soils and the cave were collected from March to May 2012 to implement a multicomponent hydrograph separation approach using δ18O and δ2H of water and dissolved inorganic carbon (δ13C–DIC). During baseflow, median δ2H and δ18O compositions were –41.6‰ and –6.2‰ for soil water and were –37.2‰ and –5.9‰ for cave water, respectively. Median DIC concentrations for soil and cave waters were 1.8 mg/L and 25.0 mg/L, respectively, and median δ13C–DIC compositions were –19.9‰ and –14.3‰, respectively. During a March storm event, 12.2 cm of precipitation fell over 82 h and discharge increased from 0.01 to 0.59 m3/s. The isotopic composition of precipitation varied throughout the storm event because of rainout, a change of 50‰ and 10‰ for δ2H and δ18O was observed, respectively. Although, at the spring, δ2H and δ18O only changed by approximately 3‰ and 1‰, respectively. The isotopic compositions of precipitation and pre-event (i.e., soil and bedrock matrix) water were isotopically similar and the two-component hydrograph separation was inaccurate, either overestimating (>100%) or underestimating (<0%) the precipitation contribution to the spring. During the storm event, spring DIC and δ13C–DIC decreased to a minimum of 8.6 mg/L and –16.2‰, respectively. If the contribution from precipitation was assumed to be zero, soil water was found to contribute between 23 to 72% of the total volume of discharge. Although the assumption of negligible contributions from precipitation is unrealistic, especially in karst systems where rapid flow through conduits occurs, the hydrograph separation using inorganic carbon highlights the importance of considering vadose-zone soil water when analyzing storm chemohydrographs.
