Functional Outcome in Patients With Schizophrenia: The Concept and Measurement
Authors: Sumiyoshi Chika , Sumiyoshi Tomiki 
Published: February 2017

Abstract
Functional outcome has attracted interest from the perspective of interventions in patients with schizophrenia. It includes a wide range of abilities, from successful performance on neurocognitive tests to living independently in the community. The functional outcome is classified into three levels: neuropsychological performance, functional capacity, and functional performance. In the last decades, much effort has been directed into the development of assessment measures covering these domains of functional outcomes. The paper presents the concept of functional outcome and an overview of the assessments tools. Factors affecting predictability of functional outcomes and cautions in the process of translation into foreign languages are also discussed.
Religious Experiences and Mind-Brain Sciences in the 21st Century
Authors: Laker Matthew K. 
Published: February 2017

AbstractThe classical work by William James in context of current ideas in religion and modern psychology points to the difference between a “moralist” and a religious or mystical understanding. James described that specific psychological mechanisms related to religious experience (“re-unification”) are compensatory influences on divided consciousness or heterogeneous self, which is determined by a conflict between moral and immoral behavior symbolized by a personified evil as for example the ‘Satan’. According to recent findings there is not widely accepted evidence about specific neural mechanisms of these processes related to psychological integration and re-unification. Nevertheless recent findings indicate very specific and significant influences of these specific experiences related to meditation on brain functions and morphology.

On the local solution of the tangential Cauchy–Riemann equations

We study the solution operators

D

on a strictly pseudoconvex real hypersurface in complex

n

-space. The main difficulties stem from the fact that

P

is an integral operator with a rather complicated kernel. For

-norm estimate of the form

∥Pφ∥_{U, k} ≦ K∥φ∥_{D, k}

K

on the derivatives of the function defining the real hypersurface. Our estimates are sufficient for application to the local CR embedding problem.

On the proof of Kuranishi’s embedding theorem

Natural convection in a corrugated slot
Authors: Abtahi Arman , Floryan J. M. 
Published: February 2017

Analysis of natural convection in a horizontal slot formed by two corrugated isothermal plates has been carried out. The analysis is limited to subcritical Rayleigh numbers$Ra$where no secondary motion takes place in the absence of corrugations. The corrugations have a sinusoidal form characterized by the wavenumber, the upper and lower amplitudes and the phase difference. The most intense convection occurs for corrugation wavelengths comparable to the slot height; it increases proportionally to$Ra$and proportionally to the corrugation height. Placement of corrugations on both plates may either significantly increase or decrease the convection depending on the phase difference between the upper and lower corrugations, with the strongest convection found for corrugations being in phase, i.e. a ‘wavy’ slot, and the weakest for corrugations being out of phase, i.e. a ‘converging–diverging’ slot. It is shown that the shear forces would always contribute to the corrugation build-up if erosion was allowed, while the role of pressure forces depends on the location of the corrugations as well as on the corrugation height and wavenumber, and the Rayleigh number. Placing corrugations on both plates results in the formation of a moment which attempts to change the relative position of the plates. There are two limiting positions, i.e. the ‘wavy’ slot and the ‘converging–diverging’ slot, with the latter being unstable. The system would end up in the ‘wavy’ slot configuration if relative movement of the two plates was allowed. The presence of corrugations affects the conductive heat flow and creates a convective heat flow. The conductive heat flow increases with the corrugation height as well as with the corrugation wavenumber; it is largest for short-wavelength corrugations. The convective heat flow is relevant only for wavenumbers of$O(1)$, it increases proportionally to$Ra^{3}$and proportionally to the second power of the corrugation height. Convection is qualitatively similar for all Prandtl numbers$Pr$, with its intensity increasing for smaller$Pr$and with the heat transfer augmentation increasing for larger$Pr$.

AbstractThe purpose of this study is to examine inclusive leadership as a predictor of innovative work behavior with the mediating role of psychological safety. Data were collected from supervisors–subordinates dyads working in textile industry in Pakistan. Our findings suggest that inclusive leadership is a positively related with innovative work behavior, and psychological safety mediates the effect of inclusive leadership on innovative work behavior. The leader–member exchange theory was used to build our theoretical model. We have also discussed theoretical and practical implications of our findings.

Cost-effectiveness of computerized cognitive–behavioural therapy for the treatment of depression in primary care: findings from the Randomised Evaluation of the Effectiveness and Acceptability of Computerised Therapy (REEACT) trial
Authors: Duarte A. , Walker S. , Littlewood E. , Brabyn S. , Hewitt C. , Gilbody S. , Palmer S. 
Published: February 2017

BackgroundComputerized cognitive–behavioural therapy (cCBT) forms a core component of stepped psychological care for depression. Existing evidence for cCBT has been informed by developer-led trials. This is the first study based on a large independent pragmatic trial to assess the cost-effectiveness of cCBT as an adjunct to usual general practitioner (GP) care compared with usual GP care alone and to establish the differential cost-effectiveness of a free-to-use cCBT programme (MoodGYM) in comparison with a commercial programme (Beating the Blues) in primary care.MethodCosts were estimated from a healthcare perspective and outcomes measured using quality-adjusted life years (QALYs) over 2 years. The incremental cost-effectiveness of each cCBT programme was compared with usual GP care. Uncertainty was estimated using probabilistic sensitivity analysis and scenario analyses were performed to assess the robustness of results.ResultsNeither cCBT programme was found to be cost-effective compared with usual GP care alone. At a £20 000 per QALY threshold, usual GP care alone had the highest probability of being cost-effective (0.55) followed by MoodGYM (0.42) and Beating the Blues (0.04). Usual GP care alone was also the cost-effective intervention in the majority of scenario analyses. However, the magnitude of the differences in costs and QALYs between all groups appeared minor (and non-significant).ConclusionsTechnically supported cCBT programmes do not appear any more cost-effective than usual GP care alone. No cost-effective advantage of the commercially developed cCBT programme was evident compared with the free-to-use cCBT programme. Current UK practice recommendations for cCBT may need to be reconsidered in the light of the results.
Laser generated Richtmyer–Meshkov and Rayleigh–Taylor instabilities and nonlinear wave-vortex paradigm in turbulent mixing. II. Near-central region of Gaussian spot
Authors: Lugomer Stjepan 
Published: February 2017

AbstractLaser-induced three-dimensional (3D) Richtmyer–Meshkov and Rayleigh–Taylor instabilities (RMI and RTI) on metal target in the semi-confined configuration (SCC) show the new paradigm of wave-vortex mixing. The SCC enables extended lifetime of a hot vapor/plasma plume above the target surface and the formation of fast multiple reshocks. This causes – in the central region (CR) of Gaussian-like spot – the evolution of RMI with the spike breakup (Lugomer, 2016b), while in the near CR causes the RMI followed by the RTI. The density interface is transformed into the large-scale broken irregular, quasi-periodic web, which comprises the RTI mushroom-shape spikes and the coherent wave-vortex structures such as the line solitons and vortex filaments. The intensity and direction of reshocks change (due to irregularity of the interface) and cause the formation of domains with the weak and the strong reshocks effects. The weak reshocks affect mushroom-shape spikes only slightly, while the strong ones cause their deformation and symmetry break, bubble collapse, and separation of the horizontal flow into vortex ribbons. Interaction of ribbons with spikes and bubbles causes the ribbon pinning, looping, winding, and formation of knotted and tangled structures. The line solitons, vortex filaments, and ribbons tend to organize into complex large-scale structures with the low wave-vortex turbulent mixing. They represent the new paradigm of 3D RMI and RTI in which the transition to the small-scale turbulent mixing does not appear.
Soldiers as Victims at the ECCC: Exploring the Concept of ‘Civilian’ in Crimes against Humanity
Authors: KILLEAN RACHEL , DOWDS EITHNE , KRAMER AMANDA 
Published: February 2017

AbstractThe inspiration for this article came from a call foramicus curiaebriefs issued in April 2016 by the Office of the Co-Investigating Judges in the Extraordinary Chambers in the Courts of Cambodia (ECCC). The call sought guidance on: whether, under customary international law applicable between 1975 and 1979, an attack by a state or organization against members of its own armed forces may amount to an attack directed against a civilian population for the purpose of constituting a crime against humanity under Article 5 of the ECCC Law. We argue that customary international law justifies a finding that an attack on members of the armed forces can constitute crimes against humanity. In particular, the article focuses on the importance placed on the persecution element of crimes against humanity in the post-Second World War jurisprudence, and the broad interpretation of the term ‘civilian’. The article also examines the jurisprudence of contemporary international courts, finding that in some cases the courts have interpreted the term ‘civilian’ as incorporatinghors de combat. However, the International Criminal Tribunal for the former Yugoslavia (ICTY) and International Criminal Court (ICC) have moved towards a more restrictive interpretation of the term ‘civilian’, potentially excluding members of the armed forces. We argue that this move is regressive, and against the spirit in which the offence of crimes against humanity was created. The ECCC has an opportunity to counter this restrictive approach, thereby narrowing the protection gap which crimes against humanity were initially created to close.
Eyetracking methodology in SCMC: A tool for empowering learning and teaching
Authors: Stickler Ursula , Shi Lijing 
Published: February 2017

AbstractComputer-assisted language learning, or CALL, is an interdisciplinary area of research, positioned between science and social science, computing and education, linguistics and applied linguistics. This paper argues that by appropriating methods originating in some areas of CALL-related research, for example human-computer interaction (HCI) or psycholinguistics, the agenda of “attention-focus” research can be shifted from a cognitive perspective to a learner-centred approach; understanding online language learning and teaching spaces as mediated by technology; second/foreign language learning; and online teaching culture.Taking a method that has traditionally been used within a positivist paradigm, the authors exemplify the potential of eyetracking to advance online language learning research – extending it in ways compatible with a sociocultural paradigm. This is evidenced by two pioneering studies in which an innovative combination of methods allows participants, whose gaze focus was recorded during synchronous computer-mediated communication (SCMC), to reflect back on their involvement. Eyetracking is combined with stimulated recall interviews that trigger deep reflection on learner and teacher strategies by directing participants’ recollections on their attention focus.The rich, multifaceted results shown by this original and innovative use of eyetracking methods in a sociocultural framework suggest a way forward in researching online learning by integrating insider and outside views coherently and systematically.
Significance of the globally threatened Straw-headed Bulbul Pycnonotus zeylanicus populations in Singapore: a last straw for the species?
Authors: YONG DING LI , LIM KIM SENG , LIM KIM CHUAH , TAN TRIXIE , TEO SIYANG , HO HUA CHEW 
Published: February 2017

SummaryThe globally threatened Straw-headed Bulbul Pycnonotus zeylanicus is one of South-East Asia’s most imperilled songbirds due to the surging demand for the species in the regional bird trade. Recently uplisted from Vulnerable to Endangered, populations of the Straw-headed Bulbul have been extirpated from Java, Thailand and possibly Sumatra while those in Borneo and Peninsular Malaysia are in decline. Intriguingly, a significant yet rarely documented population of this species persists in Singapore. A major stronghold in Singapore is Ubin Island where a population is known since the 1920s. Using a long-term citizen science dataset rarely available for South-East Asian bird species, we determined the status and population trends of the Straw-headed Bulbul in Singapore over a 10–15 year period using Poisson regression models and standardised population indices. We found that the Straw-headed Bulbul population has increased at a rate of 3.69 ± 1.21% per annum on Ubin Island, while the population on Singapore Island remained stable (0.56% per annum) from 2000 to 2016. The population trends in Singapore contrast starkly with the declines reported elsewhere in South-East Asia. We estimated the population in Singapore to be a minimum of 202 individuals, distributed over multiple forest patches. The largest subpopulation of about 110 adult individuals persists on Ubin and which alone forms between 6.5–18.3% of the estimated global population in 2016. Given this unique situation, we recommend a number of conservation measures for the Straw-headed Bulbul to better protect the species, including: (1) an expansion of the protected area network in Singapore to include Ubin as a reserve, (2) the development of an endangered species management plan and, (3) the establishment of ex-situ conservation programmes in zoological institutions and wildlife centres in the region.
