Quantum and classical properties of the fields generated by two interlinked second-order non-linear interactions

We consider two interlinked non-linear interactions occurring simultaneously in a single chi((2)) crystal. Classical and quantum working regimes are considered and their peculiar properties analysed. In particular, we describe an experiment, realized in the classical regime, that verifies the holographic nature of the process, and predict, for the quantum regime, the generation of a fully inseparable tripartite Gaussian state of light that can be used to support a general 1--> 2 continuous variable telecloning protocol.

The Role of Victims in the International Criminal Tribunals of the Second World War

This article analyses the role of victims within the founding international criminal tribunals of the Second World War, drawing from historical research of the practice and judgements of the Nuremberg and Tokyo tribunals. While some commentators have decried the absence of victims at Nuremberg and Tokyo, numerous victim-witnesses testified before these tribunals. However, the outcome of these tribunals has been disappointing to victims who still seek justice over sixty-five years later. This article considers the implications of the Nuremberg and Tokyo tribunals not providing justice to victims and how this has impacted on their legacy. Although these tribunals are neglected in contemporary discussions of victim provisions, they can still provide some important lessons for modern international criminal justice mechanisms, such as the International Criminal Court, to learn from.

Loss of Synaptic Connectivity, Particularly in Second Order Neurons Is a Key Feature of Diabetic Retinal Neuropathy in the Ins2Akita Mouse

Retinal neurodegeneration is a key component of diabetic retinopathy (DR), although the detailed neuronal damage remains ill-defined. Recent evidence suggests that in addition to amacrine and ganglion cell, diabetes may also impact on other retinal neurons. In this study, we examined retinal degenerative changes in Ins2^Akita diabetic mice. In scotopic electroretinograms (ERG), b-wave and oscillatory potentials were severely impaired in 9-month old Ins2^Akita mice. Despite no obvious pathology in fundoscopic examination, optical coherence tomography (OCT) revealed a progressive thinning of the retina from 3 months onwards. Cone but not rod photoreceptor loss was observed in 3-month-old diabetic mice. Severe impairment of synaptic connectivity at the outer plexiform layer (OPL) was detected in 9-month old Ins2Akita mice. Specifically, photoreceptor presynaptic ribbons were reduced by 25% and postsynaptic boutons by 70%, although the density of horizontal, rod- and cone-bipolar cells remained similar to non-diabetic controls. Significant reductions in GABAergic and glycinergic amacrine cells and Brn3a+ retinal ganglion cells were also observed in 9-month old Ins2^Akita mice. In conclusion, the Ins2^Akita mouse develops cone photoreceptor degeneration and the impairment of synaptic connectivity at the OPL, predominately resulting from the loss of postsynaptic terminal boutons. Our findings suggest that the Ins2^Akita mouse is a good model to study diabetic retinal neuropathy.

Controlling the materials properties and nanostructure of a single-component dendritic gel by adding a second component

This paper reports a dendritic system which is capable of forming both one-component and two-component gels interestingly the addition of the second component can either increase or decrease the degree of gelation, depending on dendritic generation.

Second Equal Treatment Act for the commercial sector

This book analyses one of the first pieces of legislation promoted by Angela Merkel, who started her political career as a minister for women's equality under Helmut Kohl. The name of the Act, Second Equal Treatment Act, allured to the Equal Treatment Act of the 1950s which implemented the barest minimum requirements to make the German constitution's demand to guarantee equal rights for women more than a hollow formula. However, this Act, while abolishing blatant discrimination of women through statute in fields such as family law, did nothing to further substantive equality. In 1990, when Germany was reunited, women from Eastern Germany had a first hand experience what the absence of such furtherance meant under capitalism. Used to being at nor risk to fall into poverty just because they divorced, or decided to become a mother without male protection, to being in full employment and not at the mercy of payments by their husbands, women from Eastern Germany were dismissed in large numbers, and found themselves sent back to the kitchen. The first minister for women affairs from their ranks made the "2nd Equality Act", but this act did little more than the minimum required by the EEC legislation. Again, substantive equality was not addressed through German Federal legislation. This was left to some of the German states - whose competences were limited to the public services. Most of those states which did create positive action measures for women employed in the public services were governed not by Christian Democrats - but this was the theme of another book.

A New Analysis of Mars "Special Regions": Findings of the Second MEPAG Special Regions Science Analysis Group (SR-SAG2)

A committee of the Mars Exploration Program Analysis Group (MEPAG) has reviewed and updated the description of Special Regions on Mars as places where terrestrial organisms might replicate (per the COSPAR Planetary Protection Policy). This review and update was conducted by an international team (SR-SAG2) drawn from both the biological science and Mars exploration communities, focused on understanding when and where Special Regions could occur. The study applied recently available data about martian environments and about terrestrial organisms, building on a previous analysis of Mars Special Regions (2006) undertaken by a similar team. Since then, a new body of highly relevant information has been generated from the Mars Reconnaissance Orbiter (launched in 2005) and Phoenix (2007) and data from Mars Express and the twin Mars Exploration Rovers (all 2003). Results have also been gleaned from the Mars Science Laboratory (launched in 2011). In addition to Mars data, there is a considerable body of new data regarding the known environmental limits to life on Earth—including the potential for terrestrial microbial life to survive and replicate under martian environmental conditions. The SR-SAG2 analysis has included an examination of new Mars models relevant to natural environmental variation in water activity and temperature; a review and reconsideration of the current parameters used to define Special Regions; and updated maps and descriptions of the martian environments recommended for treatment as “Uncertain” or “Special” as natural features or those potentially formed by the influence of future landed spacecraft. Significant changes in our knowledge of the capabilities of terrestrial organisms and the existence of possibly habitable martian environments have led to a new appreciation of where Mars Special Regions may be identified and protected. The SR-SAG also considered the impact of Special Regions on potential future human missions to Mars, both as locations of potential resources and as places that should not be inadvertently contaminated by human activity.

Promoting normality in the management of the perineum during the second stage of labour

The management of the perineum during birth has multiple long-term effects on women and their families. The midwife has a key role to play and often the techniques they employ vary significantly, as does their justification of these practices. This article seeks to examine current evidence to explore what is known to contribute to lower perineal trauma rates and what practices should be avoided to protect childbearing women. The conclusions drawn show that the updating of
practice and antenatal education may be required so that woman are given the information they need to make an informed choice as to what they want for their own body, child and experience.

A Lagrangian approach for modeling road collisions using second-order models of traffic flow

In [M. Herty, A. Klein, S. Moutari, V. Schleper, and G. Steinaur, IMA J. Appl. Math., 78(5), 1087–1108, 2013] and [M. Herty and V. Schleper, ZAMM J. Appl. Math. Mech., 91, 763–776, 2011], a macroscopic approach, derived from fluid-dynamics models, has been introduced to infer traffic conditions prone to road traffic collisions along highways’ sections. In these studies, the governing equations are coupled within an Eulerian framework, which assumes fixed interfaces between the models. A coupling in Lagrangian coordinates would enable us to get rid of this (not very realistic) assumption. In this paper, we investigate the well-posedness and the suitability of the coupling of the governing equations within the Lagrangian framework. Further, we illustrate some features of the proposed approach through some numerical simulations.

Evaluation of an Older Persons’ Assessment Educational Workbook with second year nursing students in the UK.

Background: As a first step to successfully meet the complex health and social needs of older people, patient assessment has become a central feature of government policy and practice in order to ensure that care planning is person-centred. A core component of nurse education is clinical practice in order to support the development of clinical skills and competence; therefore it is important to help students and their practice-based mentors to develop and apply older person assessment skills. Therefore, an educational workbook was developed to help 2nd year nursing students to learn a structured, systematic and individualised older person assessment process with the support of their mentor.

Aim: A pilot study to evaluate the impact of an Older Persons’ Assessment Educational Workbook and explore second year nursing students’ competence and their opinions and use of an older person’s assessment skills workbook.

Research Methodology: A pre-experimental design (pre and post-test with no comparison group) was undertaken with n=6 2nd year students in 2014. The outcome measure was the Nursing Competence Questionnaire and results were analysed using the Wilcoxin Signed Rank Test in SPSS version 21. Content analysis of completed workbooks and a survey (n=5) of opinions regarding the workbook was undertaken.

Key Findings- No pre-post-test difference was found in the Nursing Competence Questionnaire with p=0.058 for the total scale. However, as this was a pilot, the study was under-powered and all students’ scores improved. Content analysis of the workbook found that 3 of the 5 participants completed all components of the workbook, with a mean of 1051 words used (Std dev 281.8). Through the survey students reported the workbook as a useful guide when undertaking a patient assessment.

Conclusions: The workbook showed potential as an intervention to help support development of nursing students’ assessment skills in practice.

165/183 GHz FSS for the MetOp Second Generation Microwave Sounder Instrument

This paper reports the design of a Frequency Selective Surface (FSS) which simultaneously allows transmission of 175.3 – 191.3 GHz radiation and rejection from 164 - 167 GHz with a loss <0.5 dB for TE wave polarization at 45° incidence. The state-of-the art filter consists of three air spaced perforated screens with unit cells that are composed of nested resonant slots. The FSS satisfies the stringent electromagnetic performance requirements for signal demultiplexing in the quasi-optical feed train of the Microwave Sounder (MWS) instrument which is under development for the MetOp-SG mission.
