Enhancing Occupational Therapy Students’ Knowledge, Competence, Awareness, and Interest in Accessibility
Authors: Bar Michal Avrech , Ratzon Navah Z. 
Published: June 2016

Objective/Background The purpose of this study was to assess whether the incorporation of an environmental assessment for accessibility, as part of an “Activity Analysis” course, would enhance new students’ knowledge, competence, awareness, and interest in accessibility issues for people with disabilities. Methods In this research, we included an out-of-class training of environmental assessment for accessibility. One hundred and two 1st-year occupational therapy students at Tel Aviv University participated in this research. Of the 102 participants, 56 experienced the training and 46 did not but attended the regular Activity Analysis course. The students explored a typical community environment, during which a specific checklist was used for assessing levels of accessibility. The “Accessibility-Knowledge Competence Awareness and Interests” questionnaire was administered before and after the course to both groups. Results Students who participated in the out-of-class training showed significant increases in their knowledge, competence, and partial awareness of accessibility and also had better grades in two separate courses that required knowledge of accessibility. There was no significant difference in the results of the Accessibility-Knowledge Competence Awareness and Interests before and after the Activity Analysis course in the control group. Conclusion The findings of the current study support the contribution of teaching 1st-year occupational therapy students the principles and practices of accessibility for people with disabilities, by improving their knowledge and level of competence at this early stage of their professional lives. Further studies are needed, however, to determine the optimal course of implementation in order to enhance awareness and interest in the subject of accessibility.
Shock-tunnel investigations on the evolution and morphology of shock-induced large separation bubbles
Authors: Sriram R. , Jagadeesh G. 
Published: June 2016

ABSTRACTShock-tunnel experiments are carried out to study the strong interaction between an impinging shock wave and boundary layer on a flat plate, accompanied bylargeseparation bubble with a length comparable to the distance of the location of shock impingement from the leading edge of the plate. For nominal freestream Mach numbers ranging from 6 to 8.5, moderate to high total enthalpies of 1.3MJ/kg to 6MJ/kg are simulated in the Indian Institute of Science's hypersonic shock tunnels HST-2 (a conventional Hypersonic Shock Tunnel) and Free Piston Shock Tunnel (FPST) with freestream Reynolds numbers ranging from 4 × 106/m to 0.3 × 106/m. The strong impinging shock is generated by a wedge (or shock generator) at an angle of 30.96° to the freestream. From the time-resolved Schlieren flow visualisations using a high-speed camera and surface pressure measurements on the flat plate using fast response sensors, a statistically steady flow field with a large separation bubble was established within the short test time of the shock tunnels (around 600µs in HST-2 and 300µs in FPST). The role of various parameters on the interaction – Mach number, location of shock impingement and flow total enthalpy – are investigated from the measured separation length and surface pressure distribution. For the nominal Mach number of 8.5, with shock impingement at 100mm from the leading edge, the separation length increased from 60mm to 70mm as the total enthalpy is increased from 1.6MJ/kg to 2.4MJ/kg; whereas it dropped drastically to 30-40mm at 6MJ/kg. This is due to the prominence of real gas effects at higher enthalpies.
EQUITABLE RETIREMENT INCOME TONTINES: MIXING COHORTS WITHOUT DISCRIMINATING
Authors: Milevsky Moshe A. , Salisbury Thomas S. 
Published: June 2016

AbstractThere is growing interest in the design of pension annuities that insure against idiosyncratic longevity risk while pooling and sharing systematic risk. This is partially motivated by the desire to reduce capital and reserve requirements while retaining the value of mortality credits; see for example, Piggott et al. (2005) or Donnelly et al. (2014). In this paper, we generalize the natural retirement income tontine introduced by Milevsky and Salisbury (2015) by combining heterogeneous cohorts into one pool. We engineer this scheme by allocating tontine shares at either a premium or a discount to par based on both the age of the investor and the amount they invest. For example, a 55-year old allocating $10,000 to the tontine might be told to pay $200 per share and receive 50 shares, while a 75-year old allocating $8,000 might pay $40 per share and receive 200 shares. They would all be mixed together into the same tontine pool and each tontine share would have equal income rights. The current paper addresses existence and uniqueness issues and discusses the conditions under which this scheme can be constructed equitably — which is distinct from fairly — even though it isn't optimal for any cohort. As such, this also gives us the opportunity to compare and contrast various pooling schemes that have been proposed in the literature and to differentiate between arrangements that are socially equitable, vs. actuarially fair vs. economically optimal.
Evaporation of water: evaporation rate and collective effects

Published: June 2016

We study the evaporation rate from single drops as well as collections of drops on a solid substrate, both experimentally and theoretically. For a single isolated drop of water, in general the evaporative flux is limited by diffusion of water through the air, leading to an evaporation rate that is proportional to the linear dimension of the drop. Here, we test the limitations of this scaling law for several small drops and for very large drops. We find that both for simple arrangements of drops, as well as for complex drop size distributions found in sprays, cooperative effects between drops are significant. For large drops, we find that the onset of convection introduces a length scale of approximately 20 mm in radius, below which linear scaling is found. Above this length scale, the evaporation rate is proportional to the surface area.
Measuring Noise Temperatures of Phased-Array Antennas for Astronomy at CSIRO
Authors: Chippendale A. P. , Hayman D. B. , Hay S. G. 
Published: June 2016

AbstractWe describe the development of a noise-temperature testing capability for phased-array antennas operating in receive mode from 0.7 GHz to 1.8 GHz. Sampled voltages from each array port were recorded digitally as the zenith-pointing array under test was presented with three scenes: (1) a large microwave absorber at ambient temperature, (2) the unobstructed radio sky, and (3) broadband noise transmitted from a reference antenna centred over and pointed at the array under test. The recorded voltages were processed in software to calculate the beam equivalent noise temperature for a maximum signal-to-noise ratio beam steered at the zenith. We introduced the reference-antenna measurement to make noise measurements with reproducible, well-defined beams directed at the zenith and thereby at the centre of the absorber target. We applied a detailed model of cosmic and atmospheric contributions to the radio sky emission that we used as a noise-temperature reference. We also present a comprehensive analysis of measurement uncertainty including random and systematic effects. The key systematic effect was due to uncertainty in the beamformed antenna pattern and how efficiently it illuminates the absorber load. We achieved a combined uncertainty as low as 4 K for a 40 K measurement of beam equivalent noise temperature. The measurement and analysis techniques described in this paper were pursued to support noise-performance verification of prototype phased-array feeds for the Australian Square Kilometre Array Pathfinder telescope.
Deceived by orchids: sex, science, fiction and Darwin
Authors: ENDERSBY JIM 
Published: June 2016

AbstractBetween 1916 and 1927, botanists in several countries independently resolved three problems that had mystified earlier naturalists – including Charles Darwin: how did the many species of orchid that did not produce nectar persuade insects to pollinate them? Why did some orchid flowers seem to mimic insects? And why should a native British orchid suffer ‘attacks’ from a bee? Half a century after Darwin's death, these three mysteries were shown to be aspects of a phenomenon now known as pseudocopulation, whereby male insects are deceived into attempting to mate with the orchid's flowers, which mimic female insects; the males then carry the flower's pollen with them when they move on to try the next deceptive orchid. Early twentieth-century botanists were able to see what their predecessors had not because orchids (along with other plants) had undergone an imaginative re-creation: Darwin's science was appropriated by popular interpreters of science, including the novelist Grant Allen; then H.G. Wells imagined orchids as killers (inspiring a number of imitators), to produce a genre of orchid stories that reflected significant cultural shifts, not least in the presentation of female sexuality. It was only after these changes that scientists were able to see plants as equipped with agency, actively able to pursue their own, cunning reproductive strategies – and to outwit animals in the process. This paper traces the movement of a set of ideas that were created in a context that was recognizably scientific; they then became popular non-fiction, then popular fiction, and then inspired a new science, which in turn inspired a new generation of fiction writers. Long after clear barriers between elite and popular science had supposedly been established in the early twentieth century, they remained porous because a variety of imaginative writers kept destabilizing them. The fluidity of the boundaries between makers, interpreters and publics of scientific knowledge was a highly productive one; it helped biology become a vital part of public culture in the twentieth century and beyond.
Altitude and demography among the Sherpas
Authors: Gupta Ranjan 
Published: June 2016

SummaryThe Sherpas of Upper Khumbu (above 10,000 feet), Nepal, and their migrant counterparts at lower altitudes (3000–7000 feet) in Darjeeling District, West Bengal, show no statistically significant difference in age–sex structure or mortality, while there are suggestions of some fertility reduction at the higher altitudes.

SUMMARYRed fox (Vulpes vulpes) is the most widely distributed canid in the world and an important source of multiple zoonotic pathogens capable of causing life-threatening diseases, such as rabies and alveolar echinococcosis. Informing general public of potential risks related to foxes is becoming more important since the fox densities have increased in many countries and the species is colonizing urban areas in Europe and around the world with increasing pace, bringing zoonotic pathogens to the immediate neighbourhood of humans and their companion animals. The aim of this study was to examine the parasite fauna of red foxes in Estonia. We found in Estonian foxes a total of 17 endoparasite taxa, including ten zoonotic species. All the analysed individuals were infected and the average parasite species richness was 6·37. However, the infection rates varied to a very large extent for different parasite species, ranging from 0·9 to 91·5%. Of zoonotic species, the highest infection rate was observed forAlaria alata(90·7%),Eucoleus aerophilus(87·6%) andUncinaria stenocephala(84·3%). The prevalence of tapewormEchinococcus multilocularis, a causative agent for alveolar echinococcosis, was also relatively high (31·5%), presenting a potential risk to human health.
On the generalizability of the Chunk-and-Pass processing approach: Perspectives from language acquisition and music
Authors: Lakshmanan Usha , Graham Robert E. 
Published: June 2016

AbstractChristiansen & Chater (C&C) offer the Chunk-and-Pass strategy as a language processing approach allowing humans to make sense of incoming language in the face of cognitive and perceptual constraints. We propose that the Chunk-and-Pass strategy is not adequate to extend universally across languages (accounting for typologically diverse languages), nor is it sufficient to generalize to other auditory modalities such as music.
Exploring some edges: Chunk-and-Pass processing at the very beginning, across representations, and on to action
Authors: Maier Rose , Baldwin Dare 
Published: June 2016

AbstractWe identify three “working edges” for fruitful elaboration of the Chunk-and-Pass proposal: (a) accounting for the earliest phases of language acquisition, (b) explaining diversity in the stability and plasticity of different representational types, and (c) propelling investigation of action processing.
Language acquisition is model-based rather than model-free
Authors: Wang Felix Hao , Mintz Toben H. 
Published: June 2016

AbstractChristiansen & Chater (C&C) propose that learning language is learning to process language. However, we believe that the general-purpose prediction mechanism they propose is insufficient to account for many phenomena in language acquisition. We argue from theoretical considerations and empirical evidence that many acquisition tasks are model-based, and that different acquisition tasks require different, specialized models.
What gets passed in “Chunk-and-Pass” processing? A predictive processing solution to the Now-or-Never bottleneck
Authors: Wilkinson Sam 
Published: June 2016

AbstractI agree with the existence, and importance, of the “Now-or-Never” bottleneck. However, there is a far simpler and more parsimonious solution to it. This solution is predictive processing, and the failure to view the solution that this provides fundamentally boils down to viewing prediction as one aspect of cognition, rather than as its central principle.
Improving meat quality: the blueprint approach
Authors: Warkup C. C. 
Published: June 2016

AbstractConsumer demand for meat is strongly influenced by sensory aspects of meat quality, particularly visual appeal and eating quality. One of the most important of these traits is tenderness which is notoriously complex in origin and hence difficult to control. Potential interactions between diet, pre-slaughter handling, chill rate, muscle shortening during chilling and, therefore, toughness are presented to illustrate the complexity of controlling the trait. The final eating quality result is far from predictable. The Meat and Livestock Commission (MLC) has identified the enhancement of eating quality of beef and pork as important objectives for industry. It has produced and tested blueprint specifications which aim to summarize the ‘best state of the art’ regarding eating quality at each stage of the production and processing chain. The strengths and weaknesses of this approach are discussed. The standard blueprint specification for pork produced an improvement in tenderness of 0.6 scale points (P<0.001, scale = 1 to 8) over random retail purchases of pork chops and a significant reduction in variance. However, considerable residual variation remains, providing the opportunity for greater improvements to be made in the future.
Almost in Europe? How Finland's Embarrassing Entry into Eureka Captured Policy Change
Authors: MITZNER VEERA 
Published: June 2016

AbstractCommon historical narratives of Finnish European policy emphasise the sudden and dramatic change of 1991–1995, when Finland, as a reaction to the collapse of the Soviet Union, rejected its previously cautious approach and wholeheartedly embraced the goal of joining a unified Europe. This article, however, shows that, already in the mid-1980s, the Finnish political and economic elites questioned the country's position in the Cold War order and took bold steps in order to forge closer relations with Western Europe. A key event was the struggle for membership in Eureka, a novel European project designed to enhance cooperation in high technology.
The Implications of Statements by Aboriginal Leaders for Language Teaching in Aboriginal Schools

Published: June 2016

In the Plenary Address to the Cross Cultural Issues in Educational Linguistics Conference held at Batchelor in 1987, Mandawuy Yunupingu, Principal at Yirrkala Community School, expressed the hope that a school using ‘both-ways’ curriculum would help Aboriginal people regain control of their lives. Among other things he states,
If you have control of both languages you have double power.(Yunupingu, 1987, p.4)
Clusters of suicides and suicide attempts: detection, proximity and correlates
Authors: Too L. S. , Pirkis J. , Milner A. , Spittal M. J. 
Published: June 2016

Background.A suicide cluster is defined as a higher number of observed cases occurring in space and/or time than would typically be expected. Previous research has largely focused on identifying clusters of suicides, while there has been comparatively limited research on clusters of suicide attempts. We sought to identify clusters of both types of behaviour, and having done that, identify the factors that distinguish suicide attempts inside a cluster from those that were outside a cluster.Methods.We used data from Western Australia from 2000 to 2011. We defined suicide attempts as admissions to hospital for deliberate self-harm and suicides as deaths due to deliberate self-harm. Using an analytic strategy that accounted for the repetition of attempted suicide within a cluster, we performed spatial-temporal analysis using Poisson discrete scan statistics to detect clusters of suicide attempts and clusters of suicides. Logistic regression was then used to compare clustered attempts with non-clustered attempts to identify risk factors for an attempt being in a cluster.Results.We detected 350 (1%) suicide attempts occurring within seven spatial-temporal clusters and 12 (0.6%) suicides occurring within two spatial-temporal clusters. Both of the suicide clusters were located within a larger but later suicide attempt cluster. In multivariate analysis, suicide attempts by individuals who lived in areas of low socioeconomic status had higher odds of being in a cluster than those living in areas of high socioeconomic status [odds ratio (OR) = 29.1, 95% confidence interval (CI) = 6.3–135.5]. A one percentage-point increase in the proportion of people who had changed address in the last year was associated with a 60% increase in the odds of the attempt being within a cluster (OR = 1.60, 95% CI = 1.29–1.98) and a one percentage-point increase in the proportion of Indigenous people in the area was associated with a 7% increase in the suicide being within a cluster (OR = 1.07, 95% CI = 1.00–1.13). Age, sex, marital status, employment status, method of harm, remoteness, percentage of people in rented accommodation and percentage of unmarried people were not associated with the odds of being in a suicide attempt cluster.Conclusions.Early identification of and responding to suicide clusters may reduce the likelihood of subsequent clusters forming. The mechanisms, however, that underlie clusters forming is poorly understood.
ATP2C1 gene mutations in Hailey–Hailey disease and possible roles of SPCA1 isoforms in membrane trafficking
Authors: Micaroni M , Giacchetti G , Plebani R , Xiao G G , Federici L 
Published: June 2016

AbstractATP2C1gene codes for the secretory pathway Ca2+/Mn2+-ATPase pump type 1 (SPCA1) localizing at the golgi apparatus. Mutations on the humanATP2C1gene, causing decreased levels of the SPCA1 expression, have been identified as the cause of the Hailey–Hailey disease, a rare skin disorder. In the last few years, several mutations have been described, and here we summarize how they are distributed along the gene and how missense mutations affect protein expression. SPCA1 is expressed in four different isoforms through alternative splicing of theATP2C1gene and none of these isoforms is differentially affected by any of these mutations. However, a better understanding of the tissue specific expression of the isoforms, their localization along the secretory pathway, their specific binding partners and the role of the C-terminal tail making isoforms different from each other, will be future goals of the research in this field.
Long non-coding RNA regulation of epithelial–mesenchymal transition in cancer metastasis

Published: June 2016

AbstractMetastasis is a multistep process starting with the dissemination of tumor cells from a primary site and ending with secondary tumor development in an anatomically distant location. The epithelial–mesenchymal transition (EMT), a process that endows epithelial tumor cells with mesenchymal properties including reduced adhesion and increased motility, is considered a critical step driving the early phase of cancer metastasis. Although significant progress has been made in understanding the molecular characteristics of EMT, the intracellular mechanisms driving transition through the various stages of EMT remain unclear. In recent years, an increasing number of studies have demonstrated the involvement of long non-coding RNAs (lncRNAs) in tumor metastasis through modulating EMT. LncRNAs and their associated signaling networks have now emerged as new players in the induction and regulation of EMT during metastasis. Here we summarize the recent findings and characterizations of several known lncRNAs involved in the regulation of EMT. We will also discuss the potential use of these lncRNAs as diagnostic and prognostic biomarkers as well as therapeutic targets to slow down or prevent metastatic spread of malignant tumors.

AbstractGastric cancer is one of the most common types of cancer in the world, particularly in underdeveloped countries. The mechanism of gastric cancer is less understood compared with other types of gastrointestinal (GI) cancers. Krüppel-like factor 4 (KLF4) is a zinc-finger transcription factor and is a potential tumor suppressor in GI cancers. In this study, we have generated two mouse models, Rosa-Cre;Klf4fl/fl and Lgr5-Cre;Klf4fl/fl. KLF4 was deleted by Rosa-Cre in the gastric epithelia cells or by Lgr5-Cre in the antral stem cells in the adult mice. KLF4 deletion resulted in increased proliferating cells and decreased pit mucous cells. Surprisingly, the intestinal goblet cell marker, MUC2, which is not expressed in normal gastric tissues, was strongly induced at the base of the KLF4-deleted antral glands. To understand the clinical relevance of these findings, we analyzed the expression of KLF4 and MUC2 in human gastric cancer. In a subset of human gastric cancer, the expression of KLF4 is negatively associated with MUC2 expression. In conclusion, KLF4 is essential for normal homeostasis of antral stem cells; loss of KLF4 and expression of MUC2 could be important markers for gastric cancer diagnosis.
