Simulating the environment at the helicopter-ship dynamic interface: research, development and application
Authors: Hodge S. J. , Forrest J. S. , Padfield G. D. , Owen I.
Published: February 2016

This paper presents highlights from research conducted at the University of Liverpool to determine suitable fidelity criteria and guidelines for the modelling and simulation of the helicopter-ship dynamic interface environment. The paper begins by describing the characteristics of the helicopter-ship dynamic interface, explaining the motivation behind the research and reviewing the state-of-the-art in dynamic interface simulation. The development of a dynamic interface research environment based on an existing research simulator operated by the University of Liverpool is then described, before key results from a number of piloted simulation experiments are presented. These experiments were specifically designed to address fidelity sensitivity issues, such as, are unsteady airwake models necessary, or can a steady airwake model induce appropriate levels of pilot workload? What influence does the modelled ship geometry, or choice of atmospheric wind conditions have on the airwake model and on pilot workload? Finally, the paper concludes by briefly describing the relevance of these research findings to current and future industry programmes.
Computation of stress intensity factors in functionally graded materials using partition-of-unity meshfree method
Authors: Muthu N. , Maiti S. K. , Falzon B. G. , Guiamatsia I.
Published: February 2016

This paper describes the computation of stress intensity factors (SIFs) for cracks in functionally graded materials (FGMs) using an extended element-free Galerkin (XEFG) method. The SIFs are extracted through the crack closure integral (CCI) with a local smoothing technique, non-equilibrium and incompatibility formulations of the interaction integral and the displacement method. The results for mode I and mixed mode case studies are presented and compared with those available in the literature. They are found to be in good agreement where the average absolute error for the CCI with local smoothing, despite its simplicity, yielded a high level of accuracy.
The influence of surface ply fibre angle on the compressive strength of composite laminates containing delamination
Authors: Rhead A. T. , Butler R. , Liu W. , Baker N.
Published: February 2016

A combination of uniaxial compression tests and Strip Model and Finite Element analyses of laminates artificially delaminated to create circular (±θ) sublaminates is used to assess the influence of fibre angle on the compressive strength of composite laminates.

Sublaminates with 0° < θ < 40° are found to fail by sublaminate-buckling-driven delamination propagation and provide poor tolerance of delamination. This is a consequence of their relatively high axial stiffnesses, low sublaminate buckling strains, Poisson’s ratio induced compressive transverse strains and extension-twist coupling which produces unexpected sublaminate buckling mode shapes. Sublaminates with 40° < θ < 60° are most tolerant to delamination; axial and transverse stiffnesses are minimal, formation of sublaminate buckles is resisted, high laminate buckling strains reduce interaction between laminate and sublaminate buckling mode shapes and extension-twist coupling is minimal. Sublaminates with 60° < θ < 90° are shown to produce varied tolerance of delamination. Sublaminate buckling is generally prevented owing to transverse tensile strains induced by mismatches between laminate and sublaminate Poisson’s ratios but may occur in laminates with low Poisson’s ratios.
Aerodynamic studies over a manoeuvring UCAV 1303 configuration
Authors: Chandrasekhara M. S. , McLain B. K.
Published: February 2016

The flow past an unmanned combat air vehicle (UCAV) 1303 was investigated in a water tunnel in an effort to understand the complex flow field. The UCAV 1303 is characterised by a non slender, 47° swept-leading-edge delta wing, with a cranked trailing edge, a cropped wing tip and a fuselage. It also has no vertical tail. Dye visualisation pictures and five-axis strain gage load data were obtained on a 1:72 scale model in both steady flow and while the model executed preprogrammed manoeuvres. From the strain gage data, body axis force and moment data were derived. In addition to some similarities, comparison of the flow features observed with those of more well known slender delta wing flows showed some remarkable differences such as tip-stall, the presence of two like-sense vortices on the same side of the wing, their simultaneous spiral and bubble bursting. This paper predominantly discusses the flow visualisation results and attempts to correlate the load data to some of the observed flow features.
A finite-volume gas-kinetic method for the solution of the Navier-Stokes equations
Authors: Righi M.
Published: February 2016

Gas-kinetic theory is also valid in the continuum regime: the Euler and Navier-Stokes equations can be obtained as projection of the Boltzmann equation on to the physical space (x,t). The numerical schemes derived from gas-kinetic theory are computationally more expensive than Navier-Stokes based ones, but offer advantages which have been attracting a growing level of attention: they can (i) accommodate discontinuities at cells interface, (ii) provide high-resolution fluxes, (iii) provide advantages in the simulation of turbulence, (iv) handle hypersonic and/or rarefied flows. This study extends the validation of gas-kinetic schemes investigating a few turbulent flow cases. At a slightly higher computational cost, gas-kinetic schemes provide results comparable to those obtained with well-validated Navier-Stokes schemes using the same turbulence model, grid and reconstruction order. In the case of shock-separated flows, the results obtained with the gas-kinetic scheme are even closer to experimental data. These findings are consistent with the idea that gas-kinetic theory is a physically more consistent framework for investigating the mechanics of fluids.
Robust and computational efficient autopilot design: A hybrid approach based on classic control and genetic-fuzzy sliding mode control
Authors: Babaei A. R. , Mortazavi M. , Menhaj M. B.
Published: February 2016

The purpose of this paper is developing an efficient flight control strategy in terms of time response characteristics, robustness with respect to both parametric uncertainties and un-modeled nonlinear terms, number of required measurements, and computational burden. The proposed method is based on combination of a classic controller as principal section of the autopilot and a multi-objective genetic algorithm-based fuzzy output sliding mode control (FOSMC). FOSMC not only modifies robustness of the classic controller against uncertainties and external disturbances, but also modifies its time response for wide range of commands. FOSMC is a single input-single output controller that is based on the system output instead of the system states. In this situation, the proposed autopilot does not require measurement of other variables and observer, and also it is practicable because of considerable reduction in rule inferences then computational burden. As a critical application, the proposed method is applied to design the altitude hold mode autopilot for an UAV which is non-minimum phase, uncertain, and nonlinear.
Guided wave propagation in composite laminates using piezoelectric wafer active sensors
Authors: Gresil M. , Giurgiutiu V.
Published: February 2016

Piezoelectric wafer active sensors (PWAS) are lightweight and inexpensive transducers that enable a large class of structural health monitoring (SHM) applications such as: (a) embedded guided wave ultrasonics, i.e., pitch-catch, pulse-echo, phased arrays; (b) high-frequency modal sensing, i.e., electro-mechanical impedance method; and (c) passive detection. The focus of this paper is on the challenges posed by using PWAS transducers in the composite laminate structures as different from the metallic structures on which this methodology was initially developed. After a brief introduction, the paper reviews the PWAS-based SHM principles. It follows with a discussion of guided wave propagation in composites and PWAS tuning effects. Then, the mechanical effect is discussed on the integration of piezoelectric wafer inside the laminate using a compression after impact. Experiments were performed on a glass fibre laminate, employing PWAS to measure the attenuation coefficient. Finally, the paper presents some experimental and multi-physics finite element method (MP-FEM) results on guided wave propagation in composite laminate specimens.
Validation of endurance estimates for battery powered UAVs
Authors: Traub L. W.
Published: February 2016

An experimental investigation is presented to validate endurance estimates for a battery powered flight vehicle. In this study a radio controlled model aircraft was ‘flown’ inside a wind tunnel. Various Lithium Ion batteries were used to power the model. Battery electrical characteristics were recorded during each run to assess battery discharge behaviour. Theoretical estimates based upon battery characteristics yielded endurance estimates within 3% of that measured experimentally. The discharge characteristics of the batteries were found to be the largest source of uncertainty for endurance estimates.
The optimum aeroplane and beyond
Authors: Poll D. I. A.
Published: February 2016

A summary of the ways in which aviation impacts the environment is presented and the ratio of the energy liberated during a flight to the revenue work done (ETRW) is identified as a key indicator in the assessment of environmental impact. Using the ‘Breguet’ range equation, a number of theorems relating to ETRW are derived and discussed. This is followed by an approximate analysis to produce estimates for the ETRW of aircraft currently in service. It is found that the global fleet average value for ETRW is much higher than those estimated for existing individual aircraft. An explanation of the difference is presented, with the contributions from airline operations and air traffic management identified and quantified. Consideration is then given to the potential for future reduction in ETRW through advances in materials, alternative fuels, structures, aerodynamics and propulsion technologies and the likely benefits are quantified. The improvement in ETRW that could be achieved if this parameter was minimised in the design process with the current level of technology is also considered. Finally, the likelihood of performance improvements being introduced in the short, medium and long term is briefly discussed.
Rigid body separation dynamics for space launch vehicles
Authors: Rao B. N. , Jeyakumar D. , Biswas K. K. , Swaminathan S. , Janardhana E.
Published: February 2016

This paper presents a systematic formulation for the simulation of rigid body dynamics, including the short period dynamics, inherent to stage separation and jettisoning parts of a satellite launcher. This also gives a review of various types of separations involved in a launch vehicle. The problem is sufficiently large and complex; the methodology involves iterations at successively lower levels of abstraction. The best choice to tackle such problems is to use state-of-the-art programming technique known as object oriented programming. The necessary classes have been identified to represent various entities in the launch vehicle separation process (e.g., gravity, aerodynamics, propulsion and separation mechanisms etc.). Simple linkages are modelled with suitable objects. This approach helps the designer to simulate a launch vehicle separation dynamics and also to analyse separation system performance. To examine the influence of the design variables on the separating bodies, statistical analyses have been performed on the upper stage separation process and pull out of ongoing stage nozzle from the spent stage of a multistage rocket carrier using retro rockets.
EPISTLE: High lift system design for low-noise applied to a supersonic aircraft
Authors: Herrmann U.
Published: February 2016

A new approach for low-drag high-lift system design based on the application of viscous flow solvers was developed in the EC research project EPISTLE. Two high-lift systems for a supersonic commercial transport aircraft (SCT) wing were designed, manufactured and wind-tunnel tested. The predicted large drag reductions were fully confirmed by tests at high Reynolds numbers. These drag reductions significantly reduce the low-speed noise of future SCT configurations. This was estimated by preliminary aircraft design tools. Low-speed noise reduction by aerodynamic means is obtained, as effective high-lift systems enable these aircraft to climb faster.
FAR TOO MANY WOMEN? JOHN GRAUNT, THE SEX RATIO, AND THE CULTURAL DETERMINATION OF NUMBER IN SEVENTEENTH-CENTURY ENGLAND
Authors: PELLING MARGARET
Published: February 2016

John Graunt's analysis of the London Bills of Mortality of 1662 is famous as a pioneering contribution to the study of human populations. But comparatively little attention has been given to his highly influential discovery that the numbers of men and women were evenly balanced. Why did Graunt think that what we now call the sex ratio was important, and why did he see it as essential to contradict received opinion? What can we deduce about Graunt's own attitudes to women? Why was he concerned to discredit polygamy? Further investigation suggests, not that Graunt shared the misogyny of many of his contemporaries, but that he was motivated by the dangers inherent in his own shifting religious views, which included Socinianism and anti-Trinitarianism. The religious controversialist Bernardino Ochino can be detected as a dark influence behind Graunt's thinking. An exploration of Graunt's cultural hinterland confirms that men did indeed believe that they were outnumbered by women, a conviction accentuated by the unnerving upheavals of religious conflict, plague, and civil war, and apparently confirmed by prophecy. Seventeenth-century misogyny seems to present itself to us as qualitative, but it included a numerical dimension which was in effect culturally determined.
Makasar
Authors: Tabain Marija , Jukes Anthony
Published: February 2016

Makasar is an Austronesian language belonging to the South Sulawesi subgroup within the large Western-Malayo Polynesian family. It is spoken by about two million people in the province of South Sulawesi in Indonesia, and is the second largest language on the island of Sulawesi (behind Bugis, with about three million speakers). The phonology is notable for the large number of geminate and pre-glottalised consonant sequences, while the morphology is characterised by highly productive affixation and pervasive encliticisation of pronominal and aspectual elements. The language has a literary tradition including detailed local histories (Cummings 2002), and over the centuries has been represented orthographically in many ways: with two indigenous Indic or aksara-based scripts, a system based on Arabic script, and a variety of Romanised conventions. From at least the early 18th century Macassan sailors travelled regularly to northern Australia to collect and process trepang or sea cucumber (Macknight 1976), and many loanwords passed into Aboriginal languages of the northern part of Australia (Evans 1992, 1997).
Basic Income in Our Time: Improving Political Prospects Through Policy Learning?
Authors: DE WISPELAERE JURGEN
Published: February 2016

Following the success of a recent Swiss Citizens’ Initiative to grant each citizen an unconditional income guarantee and the Finnish Government's plans to conduct the first national pilot project, the idea of a basic income as a citizens’ right has gained much prominence in the policy debate. This article reviews a number of policy developments on the ground through the lens of the policy transfer literature. In the absence of a fully developed basic income in place, proponents must rely on partially implemented schemes or proposals that differ in crucial respects from the basic income ideal. This paper outlines three sets of empirical cases and analyses what (if any) lessons we can draw from them regarding the future of basic income schemes.
Aged communities and health-care reform attitudes in the United States of America
Authors: BRAMLETT BRITTANY H.
Published: February 2016

Older adults and baby boomers have been more opposed than supportive of the Affordable Care Act (ACA), but what about older adults living in aged communities? The aged community is a social context that is important for understanding individuals' political attitudes and behaviours. We know that social contexts often constrain the information available within the community. Also recent work indicates that this happens with the aged social context as well. Older adults living among concentrations of their peers are more politically knowledgeable than older adults without the same neighbourhood context. I hypothesise that older adults living in aged communities will be more supportive of the ACA than their peers without the same context because they know more about the ACA and its age-related benefits. To test this hypothesis, I use data from the Cooperative Congressional Election Studies for the years 2009–2012 and assess whether the aged context has had an impact on residents' attitudes towards health-care reform, the ACA, specifically. I find that older residents of aged communities are more likely to report supportive attitudes in 2010 and 2012 than older residents of communities without a significant older adult presence. There is no statistically significant aged context effect in 2009 and 2011.
The Catholic and Jewish Court: Explaining the Absence of Protestants on the Nation's Highest Judicial Body
Authors: Shemtob Zachary Baron
Published: February 2016

Following the 2006 retirement of Sandra Day O'Connor and the confirmation of Samuel Alito to succeed her, Roman Catholics formed a majority on the United States Supreme Court for the first time in this institution's 210-year history. This Catholic majority was further strengthened by the appointment of Sonia Sotomayor in 2009. Perhaps even more remarkably, by the time of Elena Kagan's first case in October of 2010, not a single Protestant sat on the nation's highest judicial body.

By way of comparison, in 1960 the Court consisted of seven Protestants, one Catholic and one Jew; in 1985, eight Protestants and one Catholic sat on the Court. This phenomenon is further reflected in judicial appointments. Since 1985, only one Protestant has been appointed,4 Justice David Souter, compared to seven Catholics and three Jews. Theprima faciereason for this transformation is simple: President Reagan began the Protestant erosion by appointing two Catholics; George H.W. Bush followed by appointing a Catholic; and Bill Clinton, George W. Bush, and Barack Obama chose only Jewish and Catholic nominees. The deeper reasons, which are considerably more complex, are the focus of this article.
Parentally Mandated Religious Healing for Children: A Therapeutic Justice Approach
Authors: Loue Sana
Published: February 2016

Significant controversy surrounds individuals' reliance on religious healing approaches to the treatment of illness, particularly when such efforts focus on the provision of care for children. These approaches, rooted in organized religions and their theologies, encompass a wide range of practices, ranging from prayer, meditation, and the laying on of hands, to exorcism, speaking in tongues, Spiritism, shamanic intervention, and various rituals of Santería. Numerous faith communities espouse one or more forms of religious healing while discouraging reliance on conventional medical treatments: These communities include the Christian Science Church, the Church of the First Born, End Time Ministries, Faith Tabernacle, Followers of Christ Church, Bible Believers' Fellowship, Christ Assembly, Christ Miracle Healing Center, Church of God Chapel, Church of God of the Union Assembly, Holiness Church, Jesus Through Jon and Judy, “No Name” Fellowship, Northeast Kingdom Community Church, and The Source.

Others, such as the Assemblies of God, have moved away from an exclusive reliance on religious healing practices to a more holistic approach that combines religious-healing with at least some aspects of biomedicine. For many of these listed groups, health and illness represent the physical manifestation of moral concerns relating to salvation, which can only be addressed through religious healing.
Crumbs from the Table: The Syrophoenician Woman and International Law
Authors: Chinen Mark A.
Published: February 2016

A few years ago I visited Nicaragua as part of a program sponsored by my university. We traveled by bus to the coffee country outside of Matagalpa and met with members of the Union of Organized Women of Yasica Sur, in a community center the women had built in a hollow beside the road. The president of the group described how thirty years ago, she and a small group of women organized to improve the supply of drinking water for their children. Over time, the women moved from providing water to providing schools and bridges, and then affordable medical care and medicines. The organization now has about one thousand members and is one of the most effective in the region. Yet the needs are still great.

Many of the women had walked for over an hour in their best clothes to visit with us. As we listened to them, I heard also my aunts and grandmothers, who did not look so very different from these women, who were just as smart, determined and hard-working, and whose lives were not so very different, except their crop was not coffee: it was sugarcane and pineapple. The sense of connection was shortlived, however. There was a question-and-answer period, and the president asked us what we did at home. One of my colleagues shared she was an environmental engineer, who specialized in lakes. The president smiled and said, “We could use you here.” Then I told her I taught international law. The president listened for the translation, regarded me and said, “I am not educated. Your work is too high for me.” So much for my solidarity with the Union of Organized Women of Yasica Sur.
Torture: Judaic Twists
Authors: Crane Jonathan K.
Published: February 2016

Perhaps in part because Jews did not enjoy sovereignty for most of their history and thus rarely organized, much less directed, military institutions, the Jewish textual tradition says relatively little about the exercise of corporal punishment during warfare. This dearth of classical sources, however, does not mean that Judaism has nothing to offer contemporary deliberation about the ethics of torture. On the contrary, modern Jews plumb the textual tradition in search of prooftexts that ground their passionately held positions vis-à-vis torture. And this is precisely one of the methodological conundrums torture poses. In their search for corroborating principles, verses andhalakhah(law) for their positions, Jewish scholars often gloss over countervailing values, texts and laws. Some trot out such broad principles asbetzelem elohim(the notion that every human is made in the divine image),al tonu(do not oppress the stranger),or lagoyim(a light unto the nations),kavod habriot(respect creatures),chillul hashem(desecrating God's name), orlo ta ’amod al dam re ’echa(do not stand on your neighbor's blood) so as to condemn or condone torture without considering countervailing principles. Others point to certain laws, such as those pertaining to therodef(stopping a pursuer who has lethal intent against another) orhora’at sha’ah(emergency exigency) to justify their positions on torture—without entertaining other relevant legal precedents. And a few others blandly state Judaism's position vis-à-vis torture without providing much or any evidence supporting those claims.
Introducing Religious Reparations: Repairing the Perceptions of African Religions Through Expansions In Education
Authors: Boaz Danielle
Published: February 2016

Western bookstores today are full of small boxes that advertise “Voodoo Revenge Kit” on the front. Their short descriptions encourage anyone who wishes to harm a cheating lover and curse a difficult boss to buy this product. Companies now sell t-shirts, mugs, buttons and key chains with “voodoo dolls,” and bound figures with needles through the heart. Novels, newspapers, and movies have, for over a century, produced representations of human sacrifice, cannibalism and devil worship as rituals central to the practice Obeah, Vodou and Santeria. U.S. televangelist Pat Robertson even remarked that the catastrophic earthquake in Haiti on January 12, 2010, was God's retribution on Haitians for practicing voodoo and making a “pact with the devil.” Remarkably, few people recognize that these depictions are, to a large degree, linked to slavery and racism, which continue to leave their stain on the past and present laws of American and Caribbean nations.
Property Rights of Hindu Women: A Feminist Review of Succession Laws of Ancient, Medieval, and Modern India
Authors: Halder Debarati , Jaishankar K.
Published: February 2016

Hindu women's legal right to inherit property has been restricted from the earliest times in Indian culture. In the ancient text Manusmriti, Manu writes: “Her father protects her in childhood, her husband protects her in youth and her sons protect her in old age; a woman is never fit for independence.” However, women were not always excluded from inheriting movable or immovable property from ancestral and marital families. But their proportion of share in the property was far less than that of their male counterparts.

Throughout history, restrictions on Hindu women's property rights have undergone change, and current laws governing these rights are more liberal than those of ancient Hindu society. Patriarchal Hindu society provided women with property known as stridhan (literally, women's property or fortune), and it mainly came from marriage gifts (clothes, jewelry, and in some rare cases, landed properties). However, women were denied property rights to the ancestral or marital landed property, and their right over succession of the landed family property was limited. With the emergence of different schools of Hindu law, the concept of stridhan started expanding its literal and legal meaning, granting women more rights to certain forms of property. Later, the nineteenth and twentieth centuries witnessed the passage of several pieces of legislation that were intended to remove more of the barriers to full and equal property rights for Hindu women. Most recently, sexual discrimination in Hindu succession rules was mostly discontinued by the recent Hindu Succession (Amendment) Act (2005).
Christianity and the Legal Status of Abandoned Children in the Later Roman Empire
Authors: Tate Joshua C.
Published: February 2016

A.H.M. Jones, the great British historian of the later Roman Empire, was once asked what difference conversion to Christianity made to Rome. His answer: None. Brutal gladiatorial contests continued to be held, slavery was not abolished, and cruel penalties were laid down for seemingly minor moral infractions. Thus, Jones reasoned, the actual impact of Christianity on secular Roman society is difficult to see. Jones's view, however, has not been universally shared, particularly when it comes to the Roman legal system. Biondo Biondi saw Christianity as bringing about “un profundo rivolgimento” in late Roman law, which had ramifications in many different areas. As a religion, Christianity differed in unmistakable ways from its pagan competitors, and it would be quite surprising if these differences did not have some impact on Roman law and society when Christianity was adopted as the official state religion. The late Roman era offers a fertile testing ground for the impact a nascent religion might have on a society and its legal institutions.
The Encrypted Sermons of Sabato Morais
Authors: Cobin David M. , Schwartz Earl
Published: February 2016

In the course of researching the attitudes of nineteenth-century rabbis about American slavery, David Cobin found that the name Sabato Morais featured prominently among rabbis who had publicly expressed strong anti-slavery sentiments. This information sent Cobin to the American Jewish History Library where some of Morais's papers are archived to find original documents on the matter. There he found sermons from 1861 to 1862 with English script title pages and text all written in Pitman Shorthand, presumably by Morais himself. One of these, an undated document entitled The Slavery of the Bible, described as a lecture, seemed to be exactly on point. Cobin's first hurdle, however, was transcribing Morais's lecture. After a significant search he found Dorothy Roberts, who had become an expert on Civil War Pitman Shorthand specifically in order to engage in this kind of scholarly transcription. It was soon clear, however, that transcribing a more than one hundred and forty year-old shorthand written for oneself was not a simple matter. There were obsolete words, partial words, undecipherable words, words left out, references to obscure incidents, incomplete quotations, and words in multiple languages. Cobin enlisted the collaboration of his colleague Earl Schwartz as co-editor, and together they partnered in the transcription process with Dorothy Roberts. Roberts transcribed the shorthand as best she could. Cobin and Schwartz then researched the history, filled in the Judaic references and mined old dictionaries and their own imaginations for language of the times to fit the words Roberts could not fully transcribe. Roberts always made the final decision on the appropriateness of the editors' suggestions in light of the shorthand. This work yielded the transcribed lecture, The Slavery in the Bible that indeed spoke about slavery in the time of the Bible, but not about American slavery. Morais's focus was on a humane form of slavery in contrast to slavery in Sparta and Rome. Unlike Rabbi Morris Raphall's discourse on The Bible View of Slavery January 15, 1861 that was used by Southerners as a defense of slavery, Morais's lecture provided little material to fuel the conflagration then raging. The editors have concluded that Morais's lecture was likely delivered as a response to Raphall's widely publicized discourse. The Slavery of the Bible is included with the four transcribed Sabbath sermons published here.
The Medieval Blood Sanction and the Divine Beneficence of Pain: 1100-1450

Here the worldling now all bound in fetters lies

starts to fear his God, his tears flow from his eyes

Justice comes along, with gallows, wheel and sword:

God tells the pious man to enter Heaven's door.

Across medieval Western Europe, those who committed serious wrongs, such as homicide, arson, treason, and rape were subject to a wide range of capital punishments that were seemingly brutal, frequently bloody, and at times spectacular. Grisly images of an executioner dismembering a condemned's limbs from his torso, smashing his chest cavity, gouging his eyes, or piercing his body with hot pokers are the common stuff of scaffold art in the high Middle Ages. Such images attest to the critical role of pain in medieval capital punishment. Whereas in our day all attempts are made to render penal death painless, in the high and late Middle Ages, the tie between pain and death is not only tolerated but, at times, purposefully exacerbated.
Religious Group Autonomy: Further Reflections about what is at Stake
Authors: Brady Kathleen A.
Published: February 2016

Does the First Amendment afford religious organizations special protection when government regulation interferes with their internal activities or affairs? Nearly all scholars would agree that relief is appropriate where government regulation is designed to impede a group's religious mission or otherwise unfairly discriminate against religion, but such cases are rare. The more difficult cases involve neutral, generally applicable laws that are not intended to burden the internal operations of religious groups but, nevertheless, have that effect. Does the First Amendment provide any relief in such situations and, if so, what is the justification for this protection?

InEmployment Division v. Smith, the Supreme Court held that the First Amendment does not excuse individuals from compliance with neutral, generally applicable laws that burden religious practice. Legislatures may choose to grant relief in such situations, but if they choose not to do so, the First Amendment does not require any special accommodations or exemptions. However,Smithdid not address protections for religious groups, and, indeed, the Court has never directly addressed the scope of First Amendment protections where neutral government regulation interferes with the internal operations of religious organizations. Scholars who have debated this question have advocated a variety of positions.
Found Law, Made Law and Creation: Reconsidering Blackstone's Declaratory Theory
Authors: Brewbaker William S.
Published: February 2016

Sir William Blackstone's Commentaries on the Laws of England is arguably the single most influential work of jurisprudence in American history. Written in the late eighteenth century, it regularly appeared in American law school classrooms up until the early part of the twentieth century, when ridiculing Blackstone and the Commentaries became a part of legal academic orthodoxy and the influence of the Commentaries waned. Blackstone eventually became the poster child for everything that the realists and their descendants thought was wrong with American law—formalism, natural rights and plutocracy.

Both Blackstone's admirers and his detractors have devoted significant attention to his famous account of judging, which holds that judges find (or declare) law rather than make law. In the introduction to the Commentaries, Blackstone states that the judge's job is to determine the law “not according to his own private judgment, but according to the known laws and customs of the land;” the judge is “not delegated to pronounce a new law, but to maintain and expound the old one.” One reason Blackstone's account has been attractive in some quarters is because it supplies apparent answers to a number of problems raised by the idea of judge-made law. If judges merely find and apply authoritative law, their decisions presumptively carry the authority of the law they are applying. Because the law pre-exists the decision, the specter of retroactive liability disappears.
Religious Culture & Natural Rights: Understanding the “Paradox” of Early America
Authors: Grenda Christopher S.
Published: February 2016

Analyses of religious liberty in eighteenth-century America often seek to uncover legal principles concerning the relationship between church and state. Many such analyses focus on the Revolutionary-era writings of famous American founders and include among recent worksThe Founders on God and Government, Jefferson and Madison on the Separation of Church and State, and Thomas Jefferson and the Wall of Separation between Church and State. Related work on religious liberty in early America examines that liberty in conceptual categories derived from the First Amendment's establishment clause which states “Congress shall make no law respecting an establishment of religion.” Scholarship in this field includesThe Establishment Clause: Religion and the First Amendment and The First Freedoms: Church and State in America to the Passage of the First Amendment.

Although such scholarship has yielded important, though conflicting, results, the general search for legal principles concerning the relationship between church and state sometimes obscures important complexities in the historical sources. One such complexity is the combination of a political culture of natural rights and the religious culture of an evangelically rooted Protestantism in much of the public discourse on religious liberty in early America. Consider, for example, the two states at the American founding that scholars usually cite as representing two contrasting legal principles on the relationship between church and state, Massachusetts and Virginia. The new state of Massachusetts maintained a religious establishment supported by public taxes while the new state of Virginia did not.
West Nile virus-neutralizing antibodies in wild birds from southern Spain

Published: February 2016

West Nile virus (WNV) is an emerging vector-borne arbovirus with a zoonotic life-cycle whose main reservoir hosts are birds. In humans and horses, WNV infections rarely result in clinical disease but on occasions – depending on factors such as climatic conditions, insect communities and background immunity levels in local populations – they can lead to outbreaks that threaten public and animal health. We tested for the presence of WNV antibodies in 149 birds belonging to 32 different species. Samples were first tested using a bird-specific ELISA kit and then both positive and doubtful results were confirmed by neutralization tests using WNV and Usutu virus. WNV antibodies were confirmed in a residentSylvia melanocephalajuvenile, supporting the idea of local transmission of WNV in southern Spain in 2013. In addition, the serum from an adult blackbird (Turdus merula) showed neutralization of both WNV and Usutu virus. We discuss our results in light of the occurrence of WNV on horse farms in southern Spain in 2013.
Differential DNA methylation in peripheral blood mononuclear cells in adolescents exposed to significant early but not later childhood adversity

Published: February 2016

Internationally adopted adolescents who are adopted as young children from conditions of poverty and deprivation have poorer physical and mental health outcomes than do adolescents conceived, born, and raised in the United States by families similar to those who adopt internationally. Using a sample of Russian and Eastern European adoptees to control for Caucasian race and US birth, and nonadopted offspring of well-educated and well-resourced parents to control for postadoption conditions, we hypothesized that the important differences in environments, conception to adoption, might be reflected in epigenetic patterns between groups, specifically in DNA methylation. Thus, we conducted an epigenome-wide association study to compare DNA methylation profiles at approximately 416,000 individual CpG loci from peripheral blood mononuclear cells of 50 adopted youth and 33 nonadopted youth. Adopted youth averaged 22 months at adoption, and both groups averaged 15 years at testing; thus, roughly 80% of their lives were lived in similar circumstances. Although concurrent physical health did not differ, cell-type composition predicted using the DNA methylation data revealed a striking difference in the white blood cell-type composition of the adopted and nonadopted youth. After correcting for cell type and removing invariant probes, 30 CpG sites in 19 genes were more methylated in the adopted group. We also used an exploratory functional analysis that revealed that 223 gene ontology terms, clustered in neural and developmental categories, were significantly enriched between groups.

Background:

Delirium is a common neuropsychiatric syndrome with considerable heterogeneity in clinical profile. Rapid reliable identification of clinical subtypes can allow for more targeted research efforts.

Methods:

We explored the concordance in attribution of motor subtypes between the Delirium Motor Subtyping Scale 4 (DMSS-4) and the original Delirium Motor Subtyping Scale (DMSS) (assessed cross-sectionally) and subtypes defined longitudinally using the Delirium Symptom Interview (DSI).

Results:

We included 113 elderly patients developing DSM-IV delirium after hip-surgery [mean age 86.9 ± 6.6 years; range 65–102; 68.1% females; 25 (22.1%) had no previous history of cognitive impairment]. Concordance for the first measurement was high for both the DMSS-4 and original DMSS (k= 0.82), and overall for the DMSS-4 and DSI (k= 0.84). The DMSS-4 also demonstrated high internal consistency (McDonald's omega = 0.90). The DSI more often allocated an assessment to “no subtype” compared to the DMSS-4 and DMSS-11, which showed higher inclusion rates for motor subtypes.

Conclusions:

The DMSS-4 provides a rapid method of identifying motor-defined clinical subtypes of delirium and appears to be a reliable alternative to the more detailed and time-consuming original DMSS and DSI methods of subtype attribution. The DMSS-4, so far translated into three languages, can be readily applied to further studies of causation, treatment and outcome in delirium.

Background:

This study evaluated the impacts of earlier traumatic events on the mental health of older adults, in terms of mental disorders and mental well-being, according to sociodemographic variables, trauma-related characteristics, and personality traits in a nationally representative sample of older Koreans.

Methods:

A total of 1,621 subjects aged 60 to 74 years from a Korean national epidemiological survey of mental disorders responded face-to-face interviews. The Korean Composite International Diagnostic Interview was used to investigate lifetime trauma exposure (LTE) and psychiatric diagnoses. The EuroQol health classification system and life satisfaction scale were used to assess quality of life (QoL), and the Big Five Inventory-10 (BFI-10) to measure personality traits.

Results:

Five-hundred and seventy-seven subjects (35.6%) reported a history of LTE (mean age at trauma, 30.8 years old). Current mental disorders were more prevalent in elderly people with LTE, while better current QoL was more frequent in those without LTE. Among older people with LTE, lower extraversion and higher neuroticism increased the risk of current mood or anxiety disorders, whereas higher extraversion increased the probability of experiencing mental well-being after adjusting for sociodemographic and trauma-related variables.

Conclusion:

Personality traits, especially extraversion, and neuroticism, may be useful for predicting the mental health outcomes of LTE in older adults. Further longitudinal studies investigating the relationship between traumatic events and mental health outcomes are needed.
When My Money Becomes Our Money: Changes in Couples’ Money Management
Authors: Lott Yvonne
Published: February 2016

Conservative welfare state policies as in Germany often presume that money is a common resource within couples and, therefore, pooled. Research, however, indicates that money is increasingly managed separately or partly separately. This trend is either explained by the diversification of forms of relationships or interpreted as a general decline of the joint pooling of money. Contributing to this debate, this study investigates whether couples abandon independent money management when particular life events occur or when partners’ resources change. Data from the German Socio-Economic Panel (SOEP) for the years 2004, 2005 and 2008 are used. Panel analyses show that marriage leads to joint pooling or partly independent money management. An increase in women's incomes, however, is associated with independent money management. Women's wish for independence apparently contributes to the decline of the joint pool. The substantial prevalence of financial independence within couples calls into doubt the adequacy of German welfare state policies.
Involvement of B cells in non‐infectious uveitis

Non‐infectious uveitis—or intraocular inflammatory disease—causes substantial visual morbidity and reduced quality of life amongst affected individuals. To date, research of pathogenic mechanisms has largely been focused on processes involving T lymphocyte and/or myeloid leukocyte populations. Involvement of B lymphocytes has received relatively little attention. In contrast, B‐cell pathobiology is a major field within general immunological research, and large clinical trials have showed that treatments targeting B cells are highly effective for multiple systemic inflammatory diseases. B cells, including the terminally differentiated plasma cell that produces antibody, are found in the human eye in different forms of non‐infectious uveitis; in some cases, these cells outnumber other leukocyte subsets. Recent case reports and small case series suggest that B‐cell blockade may be therapeutic for patients with non‐infectious uveitis. As well as secretion of antibody, B cells may promote intraocular inflammation by presentation of antigen to T cells, production of multiple inflammatory cytokines and support of T‐cell survival. B cells may also perform various immunomodulatory activities within the eye. This translational review summarizes the evidence for B‐cell involvement in non‐infectious uveitis, and considers the potential contributions of B cells to the development and control of the disease. Manipulations of B cells and/or their products are promising new approaches to the treatment of non‐infectious uveitis.
Interactions between hydrology and water chemistry shape bacterioplankton biogeography across boreal freshwater networks

Disentangling the mechanisms shaping bacterioplankton communities across freshwater ecosystems requires considering a hydrologic dimension that can influence both dispersal and local sorting, but how the environment and hydrology interact to shape the biogeography of freshwater bacterioplankton over large spatial scales remains unexplored. Using Illumina sequencing of the 16S ribosomal RNA gene, we investigate the large-scale spatial patterns of bacterioplankton across 386 freshwater systems from seven distinct regions in boreal Québec. We show that both hydrology and local water chemistry (mostly pH) interact to shape a sequential structuring of communities from highly diverse assemblages in headwater streams toward larger rivers and lakes dominated by fewer taxa. Increases in water residence time along the hydrologic continuum were accompanied by major losses of bacterial richness and by an increased differentiation of communities driven by local conditions (pH and other related variables). This suggests that hydrology and network position modulate the relative role of environmental sorting and mass effects on community assembly by determining both the time frame for bacterial growth and the composition of the immigrant pool. The apparent low dispersal limitation (that is, the lack of influence of geographic distance on the spatial patterns observed at the taxonomic resolution used) suggests that these boreal bacterioplankton communities derive from a shared bacterial pool that enters the networks through the smallest streams, largely dominated by mass effects, and that is increasingly subjected to local sorting of species during transit along the hydrologic continuum.
