Inventory change (1990s–2010s) in the marine flora of Sanya Bay (Hainan Island, China)
Authors: Titlyanov Eduard A. , Titlyanova Tamara V. , Belous Oksana S. , Kalita Tatyana L.
Published: November 2014

Sanya Bay lies at the southern part of Hainan Island, 18°15′N 109°28′E. The seawater in the bay has been catastrophically polluted during the past two decades with urban sewage from the rapidly developing Sanya City. The marine flora research in Sanya Bay was started at the beginning of the 1930s and the most detailed studies were performed by two German-Chinese expeditions in 1990 (October–December) and in 1992 (March–April). In April, October, November and December 2008–2010 the marine flora of Sanya Bay was studied by the authors at three localities: Luhuitou Peninsula, Xiaodong Hai and Dadong Hai. Marine algae were sampled in the intertidal and upper subtidal zones (to 4–5 m depth). The list of species (including varieties and forms) of the marine algae for Sanya Bay sampled during the period from 2008 to 2010 is compared with those collected at the same localities in 1990/1992. Comparative analysis of the floristic composition of the marine red, brown and green algae (found during different time periods) revealed that considerable changes have taken place between 1990/1992 and 2008–2010 at Sanya Bay. There was an increase in filamentous, tubular and fine blade-like green and red algae (mainly epiphytes with a high surface to volume ratio) and a displacement of upright-growing fleshy, foliose and other large green, brown and red algae with a low surface to volume ratio. It is assumed that the changes reflect mainly increased pollution by urban sewage and mariculture pond wastes and probably by coral bleaching events of 1998.
Tilting at wildlife: reconsidering human–wildlife conflict
Authors: Redpath Stephen Mark , Bhatia Saloni , Young Juliette
Published: November 2014

Conflicts between people over wildlife are widespread and damaging to both the wildlife and people involved. Such issues are often termed human–wildlife conflicts. We argue that this term is misleading and may exacerbate the problems and hinder resolution. A review of 100 recent articles on human–wildlife conflicts reveals that 97 were between conservation and other human activities, particularly those associated with livelihoods. We suggest that we should distinguish between human–wildlife impacts and human–human conflicts and be explicit about the different interests involved in conflict. Those representing conservation interests should not only seek technical solutions to deal with the impacts but also consider their role and objectives, and focus on strategies likely to deliver long-term solutions for the benefit of biodiversity and the people involved.
Seniors' narratives of asking (and not asking) for help after a fall: implications for identity
Authors: MILLER PATRICIA A. , SINDING CHRISTINA , GRIFFITH LAUREN E. , SHANNON HARRY S. , RAINA PARMINDER
Published: November 2014

Falls among community-dwelling seniors constitute a major public health concern because of the potential morbidity and mortality associated with the fall. This study examined the informal care networks accessed by Canadian seniors who had visited the Emergency Department as a result of a fall, and considered the implications of the processes of asking for and receiving help on the senior's identity. Four themes were identified. The first was valuing independence. The remaining three themes concerned threats to the participants' identities linked to the need to ask for or receive help from family and friends. They were: becoming indebted, feeling devalued and becoming a burden to others. Seniors were noted to excuse family members from the expectation of helping because of work and family commitments, and illness. Participants described a mutually beneficial relationship with friends wherein both parties valued their independence and provided assistance to the other when needed. Their comments suggested that assistance was viewed as a good to be traded among peers. Our findings indicate that seniors value their independence and may not seek help even when it appears to be available, if asking threatens valued identities. Health and social care practitioners and policy makers responsible for planning and delivery of services should take this into account in order to ensure the best possible care for injured community-dwelling seniors.
Structure of the Li4Ti5O12 anode during charge-discharge cycling
Authors: Pang Wei Kong , Peterson Vanessa K. , Sharma Neeraj , Shiu Je-Jang , Wu She-huang
Published: November 2014

The structural evolution of the “zero-strain” Li4Ti5O12 anode within a functioning Li-ion battery during charge–discharge cycling was studied using in situ neutron powder-diffraction, allowing correlation of the anode structure to the measured charge–discharge profile. While the overall lattice response controls the “zero-strain” property, the oxygen atom is the only variable in the atomic structure and responds to the oxidation state of the titanium, resulting in distortion of the TiO6 octahedron and contributing to the anode's stability upon lithiation/delithiation. Interestingly, the trend of the octahedral distortion on charge–discharge does not reflect that of the lattice parameter, with the latter thought to be influenced by the interplay of lithium location and quantity. Here we report the details of the TiO6 octahedral distortion in terms of the O–Ti–O bond angle that ranges from 83.7(3)° to 85.4(5)°.
CaSPiS: a calculus of sessions, pipelines and services
Authors: BOREALE MICHELE , BRUNI ROBERTO , DE NICOLA ROCCO , LORETI MICHELE
Published: November 2014

Service-oriented computing is calling for novel computational models and languages with well-disciplined primitives for client–server interaction, structured orchestration and unexpected events handling. We present CaSPiS, a process calculus where the conceptual abstractions of sessioning and pipelining play a central role for modelling service-oriented systems. CaSPiS sessions are two-sided, uniquely named and can be nested. CaSPiS pipelines permit orchestrating the flow of data produced by different sessions. The calculus is also equipped with operators for handling (unexpected) termination of the partner's side of a session. Several examples are presented to provide evidence of the flexibility of the chosen set of primitives. One key contribution is a fully abstract encoding of Misra et al.'s orchestration language Orc. Another main result shows that in CaSPiS it is possible to program a ‘graceful termination’ of nested sessions, which guarantees that no session is forced to hang forever after the loss of its partner.
Generalized geometric theories and set-generated classes
Authors: ACZEL PETER , ISHIHARA HAJIME , NEMOTO TAKAKO , SANGU YASUSHI
Published: November 2014

We introduce infinitary propositional theories over a set and their models which are subsets of the set, and define a generalized geometric theory as an infinitary propositional theory of a special form. The main result is thatthe class of models of a generalized geometric theory is set-generated. Here, a class$\mathcal{X}$of subsets of a set is set-generated if there exists a subsetGof$\mathcal{X}$such that for each α ∈$\mathcal{X}$, and finitely enumerable subset τ of α there exists a subset β ∈Gsuch that τ ⊆ β ⊆ α. We show the main result in the constructive Zermelo–Fraenkel set theory (CZF) with an additional axiom, called the set generation axiom which is derivable inCZF, both from the relativized dependent choice scheme and from a regular extension axiom. We give some applications of the main result to algebra, topology and formal topology.
Some hierarchies of QCB0-spaces
Authors: SCHRÖDER MATTHIAS , SELIVANOV VICTOR
Published: November 2014

We define and study hierarchies of topological spaces induced by the classical Borel and Luzin hierarchies of sets. Our hierarchies are divided into two classes: hierarchies of countably based spaces induced by their embeddings into Pω, and hierarchies of spaces (not necessarily countably based) induced by their admissible representations. We concentrate on the non-collapse property of the hierarchies and on the relationships between hierarchies in the two classes.
An injection from the Baire space to natural numbers

We provide a realizability model based on infinite time Turing machines in which there is an injection from the internal Baire space, the object of infinite sequences of numbers, to the object of natural numbers.
Quantification of integrity
Authors: CLARKSON MICHAEL R. , SCHNEIDER FRED B.
Published: November 2014

Three integrity measures are introduced: contamination, channel suppression and program suppression. Contamination is a measure of how much untrusted information reaches trusted outputs; it is the dual of leakage, which is a measure of information-flow confidentiality. Channel suppression is a measure of how much information about inputs to a noisy channel is missing from the channel outputs. And program suppression is a measure of how much information about the correct output of a program is lost because of attacker influence and implementation errors. Program and channel suppression do not have interesting confidentiality duals. As a case study, a quantitative relationship between integrity, confidentiality and database privacy is examined.
A semiring-based trace semantics for processes with applications to information leakage analysis
Authors: BOREALE MICHELE , CLARK DAVID , GORLA DANIELE
Published: November 2014

We propose a framework for reasoning about program security building on language-theoretic and coalgebraic concepts. The behaviour of a system is viewed as a mapping from traces of high (unobservable) events to low (observable) events: the less the degree of dependency of low events on high traces, the more secure the system. We take the abstract view that low events are drawn from a generic semiring, where they can be combined using product and sum operations; throughout the paper, we provide instances of this framework, obtained by concrete instantiations of the underlying semiring. We specify systems via a simple process calculus, whose semantics is given as the unique homomorphism from the calculus into the set of behaviours, i.e. formal power series, seen as a final coalgebra. We provide a compositional semantics for the calculus in terms of rational operators on formal power series and show that the final and the compositional semantics coincide. This compositional, syntax-driven framework lays a foundation for automation and abstraction of a quantified approach to flow security of system specifications.
Hidden-Markov program algebra with iteration
Authors: MCIVER ANNABELLE , MEINICKE LARISSA , MORGAN CARROLL
Published: November 2014

We use hidden Markov models to motivate a quantitative compositional semantics for noninterference-based security with iteration, including a refinement- or ‘implements’ relation that compares two programs with respect to their information leakage; and we propose a program algebra for source-level reasoning about such programs, in particular as a means of establishing that an ‘implementation’ program leaks no more than its ‘specification’ program.

This joins two themes: we extend our earlier work, having iteration but only qualitative (Morgan 2009), by making it quantitative; and we extend our earlier quantitative work (McIver et al. 2010) by including iteration.

We advocate stepwise refinement and source-level program algebra – both as conceptual reasoning tools and as targets for automated assistance. A selection of algebraic laws is given to support this view in the case of quantitative noninterference; and it is demonstrated on a simple iterated password-guessing attack.
Quantifying information flow in cryptographic systems
Authors: BACKES MICHAEL , KÖPF BORIS
Published: November 2014

We provide a novel definition of quantitative information flow, called transmissible information, that is suitable for reasoning about informational-theoretically secure (or non-cryptographic) systems, as well as about cryptographic systems with their polynomially bounded adversaries, error probabilities, etc. Transmissible information captures deliberate communication between two processes, and it safely over-approximates the quantity of information that a process unintentionally leaks to another process.

We show that transmissible information is preserved under universal composability, which constitutes the prevalent cryptographic notion of a secure implementation. This result enables us to lift quantitative bounds of transmissible information from simple ideal functionalities of cryptographic tasks to actual cryptographic systems.

We furthermore prove a connection between transmissible information in the unconditional setting and channel capacity, based on the weak converse of Shannon's coding theorem. This connection enables us to compute an upper bound on the transmissible information for a restricted class of protocols, using existing techniques from quantitative information flow.
Non-deterministic structures of computation
Authors: FU YUXI
Published: November 2014

Divergence and non-determinism play a fundamental role in the theory of computation, and their combined effect on computational equality deserves further study. By looking at the issue from the point of view of both computation and interaction, we are led to a canonical equality for non-deterministic computation, revealing its rich algebraic structure. We study this structure in three ways. First, we construct a complete equational system for finite-state non-deterministic computation. The challenge with such a system is to find an equational alternative to fixpoint inductionà laMilner. We establish a negative result in the form of the non-existence of a finite equational system for the canonical equality of non-deterministic computation to support our approach. We then investigate infinite-state non-deterministic computation in the light of definability and show that every recursively enumerable set is generated by an unobservable process. Finally, we prove that, as far as computation is concerned, the effect produced jointly by divergence and non-determinism is model independent for a large class of process models.

We use C-graphs, which are interesting in their own right, as abstract representations of the computational objects throughout the paper.
Linearity, session types and the Pi calculus
Authors: GIUNTI MARCO , VASCONCELOS VASCO THUDICHUM
Published: November 2014

We present a type system based on session types that works on a conventional pi calculus. Types are equipped with a constructor that describes the two ends of a single communication channel, this being the only type available for describing the behaviour of channels. Session types, in turn, describe the behaviour of each individual channel end, as usual. A novel notion of typing context split allows for typing processes not typable with extant type systems. We show that our system guarantees that typed processes do not engage in races for linear resources. We assess the expressiveness of the type system by providing three distinct encodings – from the pi calculus with polarized variables, from the pi calculus with accept and request primitives, and from the linear pi calculus – into our system. For each language we present operational and typing correspondences, showing that our system effectively subsumes foregoing works on linear and session types. In the case of the linear pi calculus we also provide a completeness result.
Global progress for dynamically interleaved multiparty sessions
Authors: COPPO MARIO , DEZANI-CIANCAGLINI MARIANGIOLA , YOSHIDA NOBUKO , PADOVANI LUCA
Published: November 2014

A multiparty session forms a unit of structured communication among many participants which follow communication sequences specified as a global type. When a process is engaged in two or more sessions simultaneously, different sessions can be interleaved and can interfere at runtime. Previous work on multiparty session types has ignored session interleaving, providing a limited progress property ensured only within a single session, by assuming non-interference among different sessions and by forbidding delegation. This paper develops, besides a more traditional, compositionalcommunicationtype system, a novel staticinteractiontype system for global progress in dynamically interleaved and interfered multiparty sessions. The interaction type system infers causalities of channels making sure that processes do not get stuck at intermediate stages of sessions also in presence of delegation.
Modelling session types using contracts
Authors: BERNARDI GIOVANNI , HENNESSY MATTHEW
Published: November 2014

Session types and contracts are two formalisms used to study client–server protocols. In this paper, we study the relationship between them. The main result is the existence of a fully abstract model of session types; this model is based on a natural interpretation of these types into a subset of contracts.
On the reification of semantic linearity
Authors: GABOARDI MARCO , PAOLINI LUCA , PICCOLO MAURO
Published: November 2014

Linearity is a multi-faceted and ubiquitous notion in the analysis and development of programming language concepts. We study linearity in a denotational perspective by picking out programs that correspond to linear functions between domains.

We propose a PCF-like language imposing linear constraints on the use of variable to program only linear functions. To entail a full abstraction result, we introduce some higher-order operators related to exception handling and parallel evaluation. We study several notions of operational equivalence and show them to coincide with our language. Finally, we present a new operational evaluation of the language that provides the base for a real implementation. It exploits the denotational linearity to provide an efficient evaluation semantics SECD-like, that avoids the use of closures.
Water technology in eighteenth-century London: the London Bridge Waterworks
Authors: TOMORY LESLIE
Published: November 2014

The London Bridge Waterworks (LBWW) was founded in 1581 and lasted until the removal of the bridge in 1822. The waterworks was one of the largest water companies in London during this time. In contrast to the other water companies, its history was closely tied to both the bridge itself, as well as the City of London. Its initial growth was linked to the City's expansion, but was more limited in the eighteenth century because its pipes could not reach the expanding suburbs. This article describes the LBWW mostly at its height around 1745, when its surveyor produced a detailed engineering report of its technology.
Seeing like a cyclist: visibility and mobility in modern Dublin, c. 1930–1980
Authors: HANNA ERIKA
Published: November 2014

This article explores the visibility of the cyclist in Dublin from the 1930s to the 1980s. This visibility is explored in three ways: how the historian can and has apprehended the figure of the cyclist within the city, how the cyclist made him or herself visible within the urban environment and how cyclists were seen within techniques and conventions of urban planning. I suggest that a close examination of the place of the cyclist within the city provides a suggestive tool for understanding the implicit assumptions of urban change at mid-century.
Delayed enhancement imaging in a contemporary patient cohort following correction of tetralogy of Fallot
Authors: Preim Uta , Sommer Philipp , Hoffmann Janine , Kehrmann Jana , Lehmkuhl Lukas , Daehnert Ingo , Gutberlet Matthias , Grothoff Matthias
Published: November 2014

Objective

To test the hypothesis that myocardial scars after repair of tetralogy of Fallot are related to impaired cardiac function and adverse clinical outcome.

Methods

A total of 53 patients were retrospectively analysed after repair of tetralogy of Fallot. The median patient age was 20 years (range 2–48).

Cardiac MRI with a 1.5 T magnet included cine sequences to obtain volumes and function, phase-sensitive inversion recovery delayed enhancement imaging to detect myocardial scars, and flow measurements to determine pulmonary regurgitation fraction. In addition, clinical parameters were obtained.

Results

An overall 83% of patients were in NYHA class I. All patients with the exception of 2 (96%) had pulmonary insufficiency. Mean ejection fraction and end-diastolic volume index were 46% and 128 ml/m2 for the right ventricle and 54% and 82 ml/m2 for the left ventricle, respectively. Excluding enhancement of the septal insertion and prosthetic patches, delayed enhancement was seen in 11/53 cases (21%). Delayed enhancement of the right ventricle was detected in 6/53 patients (11%) and of the left ventricle in 5/53 patients (9%). The patient group with delayed enhancement was significantly older (p=0.003), had later repair (p=0.007), and higher left ventricular myocardial mass index (p=0.009) compared with the group without delayed enhancement.

Conclusions

This study reveals that scarring is common in patients after surgical repair of tetralogy of Fallot and is associated with older age and late repair. However, there was no difference in right ventricular function, NYHA class, or occurrence of clinically relevant arrhythmias between patients with and those without myocardial scars.
Ameliorating Patient Stigma Amongst Staff Working With Personality Disorder: Randomized Controlled Trial of Self-Management Versus Skills Training
Authors: Clarke Sue , Taylor Georgina , Bolderston Helen , Lancaster Joanna , Remington Bob
Published: November 2014

Background: Patients diagnosed with a personality disorder (PD) are often stigmatized by the healthcare staff who treat them. Aims: This study aimed to compare the impact on front-line staff of a self-management Acceptance and Commitment Therapy-based training intervention (ACTr) with a knowledge- and skills-based Dialectical Behaviour Training intervention (DBTr). Method: A service-based randomized controlled trial was conducted comparing the effects of 2-day ACTr (N = 53) and DBTr (N = 47) staff workshops over 6 months. Primary outcome measures were staff attitudes towards patients and staff-patient relationships. Results: For both interventions, staff attitudes, therapeutic relationship, and social distancing all improved pre- to postintervention, and these changes were maintained at 6-month follow-up. Conclusions: Although offering different resources to staff, both ACTr and DBTr were associated with an improved disposition towards PD patients. Future research could evaluate a combined approach, both for staff working with PD patients and those working with other stigmatized groups.
Modeling Metabolic Syndrome and Its Association with Cognition: The Northern Manhattan Study
Authors: Levin Bonnie E. , Llabre Maria M. , Dong Chuanhui , Elkind Mitchell S.V. , Stern Yaakov , Rundek Tatjana , Sacco Ralph L. , Wright Clinton B.
Published: November 2014

Metabolic syndrome (MetS) is a clustering of vascular risk factors and is associated with increased risk of cardiovascular disease. Less is known about the relationship between MetS and cognition. We examined component vascular risk factors of MetS as correlates of different cognitive domains. The Northern Manhattan Study (NOMAS) includes 1290 stroke-free participants from a largely Hispanic multi-ethnic urban community. We used structural equation modeling (SEM) to model latent variables of MetS, assessed at baseline and an average of 10 years later, at which time participants also underwent a full cognitive battery. The two four-factor models, of the metabolic syndrome (blood pressure, lipid levels, obesity, and fasting glucose) and of cognition (language, executive function, psychomotor, and memory), were each well supported (CFI=0.97 and CFI=0.95, respectively). When the two models were combined, the correlation between metabolic syndrome and cognition was −.31. Among the metabolic syndrome components, only blood pressure uniquely predicted all four cognitive domains. After adjusting for age, gender, race/ethnicity, education, smoking, alcohol, and risk factor treatment variables, blood pressure remained a significant correlate of all domains except memory. In this stroke-free race/ethnically diverse community-based cohort, MetS was associated with cognitive function suggesting that MetS and its components may be important predictors of cognitive outcomes. After adjusting for sociodemographic and vascular risk factors, blood pressure was the strongest correlate of cognitive performance. Findings suggest MetS, and in particular blood pressure, may represent markers of vascular or neurodegenerative damage in aging populations. (JINS, 2014, 20, 1–10)
Post-concussive Symptoms and Neuropsychological Performance in the Post-acute Period following Pediatric Mild Traumatic Brain Injury
Authors: Studer Martina , Goeggel Simonetti Barbara , Joeris Alexander , Margelisch Katja , Steinlin Maja , Roebers Claudia Maria , Heinks Theda
Published: November 2014

Objective: There is evidence that children after mild traumatic brain injuries (mTBI) suffer ongoing post-concussive symptoms (PCS). However, results concerning neuropsychological outcome after mTBI are controversial. Thus, our aim was to examine group differences regarding neuropsychological outcome and PCS. Additionally, we explored the influence of current and pre-injury everyday attention problems on neuropsychological outcome in children after mTBI. Method: In a prospective short-term longitudinal study, 40 children (aged 6–16 years) after mTBI and 38 children after orthopedic injury (OI) underwent neuropsychological, socio-behavioral and PCS assessments in the acute stage and at 1 week, at 4 weeks, and 4 months after the injury. Results: Parents of children after mTBI observed significantly more PCS compared to parents of children after OI, especially in the acute stage. Our results revealed no neuropsychological or socio-behavioral differences over time between both groups. However, in children after mTBI, we found negative correlations between elevated levels of everyday attention problems and reduced neuropsychological performance. Furthermore, there was a negative influence of pre-injury everyday attention problems on neuropsychological performance in children after mTBI. Conclusion: In accordance with earlier studies, parents of children after mTBI initially observed significantly more PCS compared to parents of children after OI. There were no neuropsychological or socio-behavioral group differences between children after mTBI and OI in the post-acute period. However, our exploratory findings concerning the influence of everyday attention problems on neuropsychological outcome indicate that current and pre-injury everyday attention problems were negatively associated with neuropsychological performance in children after mTBI.

Convergence of temporal reference frames in sequential bilinguals: event structuring unique to second language users
Authors: VANEK NORBERT , HENDRIKS HENRIËTTE
Published: November 2014

Previous research suggests that the way grammatical aspect is encoded in the speaker's L1 influences event conceptualisation and its subprocesses even in highly advanced L2. Given the lack of consensus regarding the susceptibility to restructuring L1 principles in L2, this work contributes to the debate with two innovative components: it tests whether the susceptibility to adjust L1 (Czech and Hungarian) structuring principles in L2 (English) is dependent on a specific degree of L1-L2 overlap in aspect marking, and it examines unique learner-specific structuring techniques that surface in picture descriptions and film retellings, to illustrate how bilinguals’ temporal reference frames converge. Besides signalling the construction of a unitary conceptual frame, L2 results clearly show the importance of language distance for explaining the nature of sequential bilinguals’ temporal structuring. To embrace the implications of the reported phenomenon, a novel proposal is developed, incorporating grammatical knowledge types already at the stage of conceptualisation.
Inverse association between soya food consumption and insulin resistance in Japanese adults
Authors: Nakamoto Mariko , Uemura Hirokazu , Sakai Tohru , Katsuura-Kamano Sakurako , Yamaguchi Miwa , Hiyoshi Mineyoshi , Arisawa Kokichi
Published: November 2014

Objective

The purpose of the present study was to examine the association between soya food consumption and insulin resistance using baseline data of the Japan Multi-Institutional Collaborative Cohort (J-MICC) Study in Tokushima, Japan.

Design

This cross-sectional study included 1274 subjects, aged 34–70 years at baseline, living in Tokushima Prefecture between 2008 and 2013. Fasting blood samples were collected and information on lifestyle characteristics including soya food intake and medical history were obtained using a structured self-administered questionnaire. The homeostasis model assessment of insulin resistance (HOMA-IR) was measured and those with HOMA-IR≥2·5 were defined as having insulin resistance. Multiple logistic regression models were used to analyse the association between soya product intake and the prevalence of insulin resistance.

Setting

Rural communities located in Tokushima Prefecture, Japan, between 2008 and 2013.

Subjects

A total of 1148 adults (565 men and 583 women), aged 34–70 years.

Results

The frequency of intake of miso soup, total non-fried soya products and total soya products showed significant inverse dose–response relationships with insulin resistance, after adjustments for potential confounders. When soya product intake was calculated as soya protein and isoflavone, the odds ratios of insulin resistance decreased significantly as the estimated intake of soya protein increased. Furthermore, significant inverse dose–response relationships were observed for total non-fried soya products and total soya products, after adjustment for total vegetable or total fibre consumption.

Conclusions

The present results indicate that the intake of soya products and non-fried soya products is associated with reduced insulin resistance in the Japanese population.
FIB-Etching of Polymer/Metal Laminates and its Effect on Mechanical Performance
Authors: Faber Enne , Vellinga Willem P. , De Hosson Jeff T.M.
Published: November 2014

This paper investigates the adhesive interface in a polymer/metal (polyethylene terephthalate/steel) laminate that is subjected to uniaxial strain. Cross-sections perpendicular to such interfaces were created with a focused ion beam and imaged with scanning electron microscopy during straining in the electron microscope. During in situ straining, glide steps formed by the steel caused traction at the interface and initiated crazes in the polyethylene terephthalate (PET). These crazes readily propagated along the free surface of the PET layer. Similar crazing has not been previously encountered in laminates that were pre-strained or in numerical calculations. The impact of focused ion beam treatments on mechanical properties of the polymer/metal laminate system was therefore investigated. It was found that mechanical properties such as toughness of PET are dramatically influenced by focused ion beam etching. It was also found that this change in mechanical properties has a different effect on the pre-strained and in situ strained samples.
Attempting to prevent postnatal depression by targeting the mother–infant relationship: a randomised controlled trial
Authors: Cooper Peter J. , De Pascalis Leonardo , Woolgar Matthew , Romaniuk Helena , Murray Lynne
Published: November 2014

Aim

The purpose of the study was to investigate whether an intervention which focused on enhancing the quality of the mother-infant relationship would prevent the development of postnatal depression (PND) and the associated impairments in parenting and adverse effects on child development.

Background

Recent meta-analyses indicate modest preventive effects of psychological treatments for women vulnerable to the development of PND. However, given the strong evidence for an impact of PND on the quality of the mother–infant relationship and child development, it is notable that there are limited data on the impact of preventive interventions on these outcomes. This is clearly a question that requires research attention. Accordingly, a randomised controlled trial (RCT) was conducted of such a preventive intervention.

Methods

A large sample of pregnant women was screened to identify those at risk of PND. In an RCT 91 were randomly assigned to receive the index intervention from research health visitors, and 99 were assigned to a control group who received normal care. In an adjacent area 76 women at risk of PND received the index intervention from trained National Health Service (NHS) health visitors. The index intervention involved 11 home visits, two antenatally and nine postnatally. They were supportive in nature, with specific measures to enhance maternal sensitivity to infant communicative signals, including items from the Neonatal Behavioral Assessment Scale. Independent assessments were made at 8 weeks, 18 weeks, and 12 and 18 months postpartum. Assessments were made of maternal mood, maternal sensitivity in mother–infant engagement, and infant behaviour problems, attachment and cognition.

Findings

The RCT revealed that the index intervention had no impact on maternal mood, the quality of the maternal parenting behaviours, or infant outcome, although there were suggestions, on some self-report measures, that those with a lower level of antenatal risk experienced benefit. This was also the case for the intervention delivered by trained NHS health visitors. The findings indicate that the approach investigated to preventing PND and its associated problems cannot be recommended.
Pathogen variation across time and space: sequencing to characterize Mannheimia haemolytica diversity
Authors: Clawson Michael L. , Murray Robert W.
Published: November 2014

Bovine respiratory disease complex (BRDC) is a major animal health and economic issue that affects cattle industries worldwide. Within the USA, the beef cattle industry loses up to an estimated 1 billion dollars a year due to BRDC. There are many contributors to BRDC, including environmental stressors and viral and/or bacterial infections. One species of bacteria in particular, Mannheimia haemolytica, is recognized as the major cause of severe fibrinonecrotic pneumonia in cattle. M. haemolytica is an opportunistic pathogen that normally populates the upper respiratory tract of cattle, and invades the lower respiratory tract in stressed and/or virally infected cattle by mechanisms that are not completely understood. However, not all M. haemolytica appear to be equally pathogenic to cattle. Thus, a test could be developed to distinguish M. haemolytica genetic subtypes by their propensity to cause respiratory disease, allowing isolation and/or treatment of cattle harboring strains with an increased propensity to cause disease. To that end, the genomes of over 300 M. haemolytica strains are being sequenced.
Evidence-based approach to improving immunity to manage cattle health
Authors: Step D. L. , Krehbiel Clint
Published: November 2014

Bovine respiratory disease (BRD) involves interactions between respiratory pathogens and stressors. Marketing beef cattle in North America frequently involves commingling of cattle from different backgrounds along with various stressors. Veterinarians are faced with unique challenges when designing preventive health care protocols. Research at Oklahoma State University has generated information to assist the practitioner to make more informed recommendations regarding the value of a single vaccination or revaccination in high-risk cattle, and the benefits of management programs at the farm or ranch of origins, particularly in regard to the impact of commingling of cattle from different origins.
Understanding the experiences of Mandarin-speaking patients diagnosed with life-threatening cancer in Australia
Authors: Chiang Yung-Chih , Collins Anna , Chopra Prem , Lu Ti , Tan Eng-Seong , Couper Jeremy W.
Published: November 2014

Objective:

People from ethnic minority groups who receive cancer care outside their country of origin may experience poor survival and psychological outcomes relative to that nation's majority groups. This exploratory qualitative study aimed to understand the experience of a large minority group of Mandarin-speaking cancer patients (MSCPs) after diagnosis and treatment of their cancer in Australia, with a view to delineate if cultural or linguistic factors affected the quality of care provided.

Method:

We employed an exploratory qualitative design involving interviews with 22 MSCPs who were treated during 2009 at the Peter MacCallum Cancer Centre (PMCC) in Melbourne, Australia. Participants were interviewed by a bilingual psychiatrist, audiotaped, transcribed in Mandarin, and then translated into English before being subjected to thematic analysis by two independent researchers.

Results:

MSCPs experienced notable challenges as a result of both language difficulties and differing cultural approaches, which often limited their understanding of their disease and impeded their ability to access quality care and adequate support. The results call for Australia and other Western nations with increasingly diverse populations to consider how cancer care can be modified to better support people from minority groups to effectively cope with their diagnosis and treatment.

Significance of results:

This study raises several suggestions for service improvement, including the development of bilingual communication aids, improved educational opportunities for clinical staff to aid their mastery of cultural issues and effective interpreter consultations, and improved access to supportive services offering culturally specific strategies.

Objective:

An important goal of cancer medicine is relief of patients' suffering. In view of the clinical challenges of identifying suffering patients, we sought to identify valid instruments for assessing the spiritual suffering of people diagnosed with cancer.

Method:

A systematic review of the literature was conducted in the Medline, Embase, the Cochrane Library, and PsycINFO databases seeking assessment instruments that measure either suffering or one of its synonyms or symptoms. The psychometric properties of the identified measures were compared.

Results:

A total of 90 articles were identified that supplied information about 58 measures. The constructs examined were: suffering, hopelessness/demoralization, hope, meaning, spiritual well-being, quality of life where a spiritual/existential dimension was included, distress in the palliative care setting and pain, distress or struggle of a spiritual nature. The Pictorial Representation of Illness and Self Measure (PRISM) (patient completed) was the most promising measure identified for measuring the burden of suffering caused by illness due to its ease of use and the inclusion of a subjective component.

Significance of Results:

Although the appropriateness of any measure for the assessment of spiritual suffering in cancer patients will depend on the context in which it is intended to be utilized, the PRISM is promising for measuring the burden of suffering due to illness.
Exploring the Factors That Encourage the Illusions of Control

Most previous research on illusions of control focused on generative scenarios, in which participants’ actions aim to produce a desired outcome. By contrast, the illusions that may appear in preventive scenarios, in which actions aim to prevent an undesired outcome before it occurs, are less known. In this experiment, we studied two variables that modulate generative illusions of control, the probability with which the action takes place, P(A), and the probability of the outcome, P(O), in two different scenarios: generative and preventive. We found that P(O) affects the illusion in symmetrical, opposite directions in each scenario, while P(A) is positively related to the magnitude of the illusion. Our conclusion is that, in what concerns the illusions of control, the occurrence of a desired outcome is equivalent to the nonoccurrence of an undesired outcome, which explains why the P(O) effect is reversed depending on the scenario.

Interleukin‐17A (IL‐17A) is a pro‐inflammatory cytokine that has an important role at mucosal sites in a wide range of immune responses including infection, allergy and auto‐immunity. γδ T cells are recognized as IL‐17 producers, but based on the level of CD3 expression, we now define the remarkable ability of a CD3bright γδ T‐cell subset with an effector memory phenotype to rapidly produce IL‐17A, but not interferon‐γ. CD3bright γδ T cells uniformly express the canonical germline encoded Vγ6/Vδ1+ T‐cell receptor. They are widely distributed with a preferential representation in the lungs and skin are negatively impacted in the absence of retinoic acid receptor‐related orphan receptor gammat expression or endogenous flora. This population responded rapidly to various stimuli in a mechanism involving IL‐23 and NOD‐like receptor family, pyrin domain containing 3 (NLRP3)‐inflammasome‐dependent IL‐1β. Finally, we demonstrated that IL‐17‐producing CD3bright γδ T cells responded promptly and strongly to pneumococcal infection and during skin inflammation. Here, we propose a new way to specifically analyze IL‐17‐producing Vγ6/Vδ1+ T cells based on the level of CD3 signals. Using this gating strategy, our data reinforce the crucial role of this γδ T‐cell subset in respiratory and skin disorders.

Submarine mud volcanoes are important sources of methane to the water column. However, the temporal variability of their mud and methane emissions is unknown. Methane emissions were previously proposed to result from a dynamic equilibrium between upward migration and consumption at the seabed by methane-consuming microbes. Here we show non-steady-state situations of vigorous mud movement that are revealed through variations in fluid flow, seabed temperature and seafloor bathymetry. Time series data for pressure, temperature, pH and seafloor photography were collected over 431 days using a benthic observatory at the active Håkon Mosby Mud Volcano. We documented 25 pulses of hot subsurface fluids, accompanied by eruptions that changed the landscape of the mud volcano. Four major events triggered rapid sediment uplift of more than a metre in height, substantial lateral flow of muds at average velocities of 0.4 m per day, and significant emissions of methane and CO2 from the seafloor.

Synthetic devices for traceless remote control of gene expression may provide new treatment opportunities in future gene- and cell-based therapies. Here we report the design of a synthetic mind-controlled gene switch that enables human brain activities and mental states to wirelessly programme the transgene expression in human cells. An electroencephalography (EEG)-based brain–computer interface (BCI) processing mental state-specific brain waves programs an inductively linked wireless-powered optogenetic implant containing designer cells engineered for near-infrared (NIR) light-adjustable expression of the human glycoprotein SEAP (secreted alkaline phosphatase). The synthetic optogenetic signalling pathway interfacing the BCI with target gene expression consists of an engineered NIR light-activated bacterial diguanylate cyclase (DGCL) producing the orthogonal second messenger cyclic diguanosine monophosphate (c-di-GMP), which triggers the stimulator of interferon genes (STING)-dependent induction of synthetic interferon-β promoters. Humans generating different mental states (biofeedback control, concentration, meditation) can differentially control SEAP production of the designer cells in culture and of subcutaneous wireless-powered optogenetic implants in mice.

We determined the electrostatic potential distribution in pristine Pt/Fe:SrTiO3/Nb:SrTiO3 structures by electron holography experiments, revealing the existence of a depletion layer extending into the Nb-doped bottom electrode. Simulations of potential profiles in metal-insulator-metal structures were conducted assuming different types and distributions of dopants. It is found that the presence of acceptor-type dopant concentrations at the Fe:SrTiO3/Nb:SrTiO3 interface with a donor-doped insulating layer provides a good match to the measured profile. Such acceptor-type interface concentrations may be associated with Sr vacancies on the Nb:SrTiO3 side of the bottom interface.
