Word learning by young sequential bilinguals: Fast mapping in Arabic and Hebrew

ABSTRACT We tested children attending bilingual Hebrew–Arabic kindergartens on a fast mapping task. These early sequential bilinguals included those with Hebrew as their home language and those with Arabic as their home language. They were compared to monolingual Hebrew and Arabic speakers. The children saw pictures of unfamiliar objects and were taught pseudowords as the object names that followed typical Hebrew, typical Arabic, or neutral phonotactics. Memory, phonological, and morphological abilities were also measured. The bilingual groups performed similarly to each other, and better than the monolingual groups, who also performed similarly to each other. Memory and the interaction between language experience and metalinguistic abilities (phonological and morphological awareness) significantly accounted for variance on the fast mapping tasks. We predicted that bilinguals would be more sensitive to phonotactics than monolinguals. Instead, we found that Arabic speakers (bilinguals and monolinguals) performed better with Hebrew-like stimuli than with Arabic-like stimuli, and no effect of phonotactics for Hebrew speakers. This may reflect the diglossia in Arabic language acquisition. The results suggest that the process of fast mapping is sharpened by multilingual experience, and may be sensitive to sociolinguistic factors such as diglossia.
Crowd Pedestrian Counting Considering Network Flow Constraints in Videos

A quadratic programming method with network flow constraints is proposed to improve crowd pedestrian counting in video surveillance. Most of the existing approaches estimate the number of pedestrians within one frame, which result in inconsistent predictions in temporal domain. In this paper, firstly, we segment the foreground of each frame into different groups, each of which contains several pedestrians. Then we train a regression-based map from low level features of each group to its person number. Secondly, we construct a directed graph to simulate people flow, whose vertices represent groups of each frame and edges represent people moving from one group to another. Then, the people flow can be viewed as an integer flow in the constructed directed graph. Finally, by solving a quadratic programming problem with network flow constraints in the directed graph, we obtain a consistent pedestrian counting. The experimental results show that our method can improve the crowd counting accuracy significantly.
Characteristics and design of coated LPFG sensor based on mode transition

The mode transition in a coated long-period fiber grating (LPFG) has been studied based on coupled-mode theory. The response of cladding mode effective index with increasing overlay thickness is analyzed. The lower order modes are transferred to the overlay, and the higher order modes replace the lower order modes order by order and continue to propagate in the cladding. Further, the transmission spectrum of the coated LPFG is investigated while the overlay thickness is located in mode transition and the surrounding region, the amplitude of attenuation peak of the cladding mode which will enter the overlay decreases rapidly and the peak position of adjacent higher cladding mode shift towards the former lower mode. To design high sensitivity LPFG sensor, the optimal overlay thickness is selected to ensure that the coated LPFG is located in the mode fast transition region. Finally, the response characteristics of film refractive index of coated LPFG were investigated for two typical cladding modes, and two kinds of the sensor sensitivity are defined and calculated. The results indicate that the resolution of film refractive index in mode transition can be available to 10-6 and 10-7 respectively, if the sensor is detected by transmittance change and wavelength shift.
Molecular Characterization of Leptospira spp. in Environmental Samples from North-Eastern Malaysia Revealed a Pathogenic Strain, Leptospira alstonii

The presence of pathogenic Leptospira spp. in the environment poses threats to human health. The aim of this study was to detect and characterize Leptospira spp. from environmental samples. A total of 144 samples comprised of 72 soil and 72 water samples were collected from markets and recreational areas in a north-eastern state in Malaysia. Samples were cultured on Ellinghausen and McCullough modified by Johnson and Harris media. Leptospires were positive in 22.9% (n = 33) of the isolates. Based on partial sequences of 16S rRNA, a pathogenic leptospire, Leptospira alstonii (n = 1/33), was identified in 3% of the isolates followed by intermediate leptospire (L. wolffii, n = 1/33, and L. licerasiae, n = 7/33) and nonpathogenic leptospire, L. meyeri (n = 22/33) in 24.2% and 66.7%, respectively. This study demonstrates the presence of a clinically significant pathogenic L. alstonii in the environments which could pose health risks to the occupants and visitors.
Expression of β-catenin in gastroenteropancreatic endocrine tumours: a study of 229 cases

Aims: To clarify the role of β-catenin in digestive endocrine carcinogenesis, a large and representative series of gastroenteropancreatic endocrine tumours was analysed in order to determine the incidence and pattern of β-catenin changes and to analyse the clinical and histological characteristics of the tumours presenting immunohistochemically detectable changes in β-catenin expression. Methods: 229 cases of gastroenteropancreatic endocrine tumours (stomach, 11; duodenum and ampulla, 29; jejunum and ileum, 51; appendix, 13; colon and rectum, 17; and pancreas, 108) were studied by immunohistochemistry to assess the pattern of distribution of β-catenin (membranous, cytoplasmic or nuclear). DNA was analysed to detect mutations in exon 3 of the CTNNB1 gene. Results: The distribution of immunoreactive β-catenin protein was membranous in 164 cases, cytoplasmic in 58 cases and nuclear in seven cases. No mutation was detected in exon 3 of the CTNNB1 gene in any case. The seven cases with nuclear accumulation of β-catenin were large tumours (mean size 44 (standard deviation (SD) 18.5) mm) with metastases, including liver metastases in five cases, high Ki-67 index (mean 34% (SD 16.5%)) and cyclin D1 overexpression; p53 accumulation was detected in six cases. Five patients died of disease; the mean (SD) survival was 13.6 (4.8) months. Conclusions: Immunohistochemically detectable nuclear accumulation of β-catenin is infrequent in gastroenteropancreatic endocrine tumours and is usually not associated with mutations in CNNTB1 exon 3. Changes in β-catenin expression are late events in digestive endocrine carcinogenesis, associated with tumour progression and dissemination.
Reduction of Brain Kynurenic Acid Improves Cognitive Function

The elevation of kynurenic acid (KYNA) observed in schizophrenic patients may contribute to core symptoms arising from glutamate hypofunction, including cognitive impairments. Although increased KYNA levels reduce excitatory neurotransmission, KYNA has been proposed to act as an endogenous antagonist at the glycine site of the glutamate NMDA receptor (NMDAR) and as a negative allosteric modulator at the α7 nicotinic acetylcholine receptor. Levels of KYNA are elevated in CSF and the postmortem brain of schizophrenia patients, and these elevated levels of KYNA could contribute to NMDAR hypofunction and the cognitive deficits and negative symptoms associated with this disease. However, the impact of endogenously produced KYNA on brain function and behavior is less well understood due to a paucity of pharmacological tools. To address this issue, we identified PF-04859989, a brain-penetrable inhibitor of kynurenine aminotransferase II (KAT II), the enzyme responsible for most brain KYNA synthesis. In rats, systemic administration of PF-04859989 dose-dependently reduced brain KYNA to as little as 28% of basal levels, and prevented amphetamine- and ketamine-induced disruption of auditory gating and improved performance in a sustained attention task. It also prevented ketamine-induced disruption of performance in a working memory task and a spatial memory task in rodents and nonhuman primates, respectively. Together, these findings support the hypotheses that endogenous KYNA impacts cognitive function and that inhibition of KAT II, and consequent lowering of endogenous brain KYNA levels, improves cognitive performance under conditions considered relevant for schizophrenia.
Echocardiographic Measurements in Normal Subjects from Infancy to Old Age

Echocardiographic data from 92 younger normal subjects (1 month to 23 years of age) and 136 o der normal subjects (20-97 years of age) were pooled and analyzed to obtain prediction equations for normal echocardiographic values. Using a bivariate regression model with the assumption that variability is constant as a percentage of the expected value, we developed regression equations and graphs that allow calculation of a 95% prediction interval for several echocardiographic measurements as a function of the subject's age and either body weight or body surface area. Body weight could be substituted for body surface area with no loss of precision. Further, examination of residuals showed that the linear prediction model fit well for all ages and all echocardiographic measurements studied. The measurements were obtained using the recently published standards recommended by the American Society of Echocardiography.
Telomerase Gene (hTERT) and Survival: Results From Two Swedish Cohorts of Older Adults

Telomere length has been associated with longevity. As telomere length is partly determined by the human telomerase reverse transcriptase (hTERT), we investigated the association between an hTERT polymorphism located in its promoter region (− 1327T/C) and longevity in two cohorts of older adults. Participants from the Kungsholmen project (KP; n = 1,205) and the Swedish National study of Aging and Care in Kungsholmen (SNAC-K; n = 2,764) were followed for an average period of 7.5 years. The main outcomes were hazard ratios (HR) of mortality and median age at death. In both cohorts, mortality was lower in female T/T carriers, aged 75+ years in KP (HR = 0.8, 95% CI: 0.5–0.9) and 78+ years in SNAC-K (HR = 0.6, 95% CI: 0.4–0.8) compared with female C/C carriers. T/T carriers died 1.8–3 years later than the C/C carriers. This effect was not present in men, neither in SNAC-K women aged 60–72 years. The association was not modified by presence of cancer, cardiovascular diseases, number of chronic diseases, or markers of inflammation, and did not interact with APOE genotype or estrogen replacement therapy. The gender-specific increased survival in T/T carriers can be due to a synergistic effect between genetic background and the life-long exposure to endogenous estrogen.
Negotiating the doctorate as an academic professional: identity work and sensemaking through authoethnographic methods

ABSTRACT This article focuses on identity flux and related negotiations that occur for doctoral students who start PhD programmes whilst already in post as full-time academics. Theoretically, we develop the concept of the learned and the learning academic as end points within a continuum used to explore academic identity negotiations. Autoethnography is here employed as a tool for reflexive engagement to illustrate how the identity sensemaking process for those who find themselves suspended in the student-lecturer ‘limbo’ is fostered by the recognition and engagement with critical incidents. Our findings contribute to studies on academic identities and to research on teaching and learning at the doctoral level by shedding light on the experience of learning and identity negotiation for a particular set of students.
A Level-Based Energy Efficiency Clustering Approach for Wireless Sensor Networks

In wireless sensor networks, energy efficiency is an important research issue. The data transmission times could be decreased effectively to achieve energy efficiency by applying a cluster-based structure. This study proposed a level-based energy efficiency clustering approach. Each cluster replaces its cluster head and re-clusters periodically according to the established energy level. A cluster head is a node that has more residual energy and lower communication cost compared to other nodes. This level-based energy efficiency clustering approach could decrease the replacement times of cluster heads, thus avoiding the excessive energy consumption caused by frequent replacement of cluster heads. The simulation results showed that this approach has less energy consumption and can effectively extend the network lifetime.
Impact of neuronal heterogeneity on correlated colored noise-induced synchronization

Synchronization plays an important role in neural signal processing and transmission. Many hypotheses have been proposed to explain the origin of neural synchronization. In recent years, correlated noise-induced synchronization has received support from many theoretical and experimental studies. However, many of these prior studies have assumed that neurons have identical biophysical properties and that their inputs are well modeled by white noise. In this context, we use colored noise to induce synchronization between oscillators with heterogeneity in both phase-response curves and frequencies. In the low noise limit, we derive novel analytical theory showing that the time constant of colored noise influences correlated noise-induced synchronization and that oscillator heterogeneity can limit synchronization. Surprisingly, however, heterogeneous oscillators may synchronize better than homogeneous oscillators given low input correlations. We also find resonance of oscillator synchronization to colored noise inputs when firing frequencies diverge. Collectively, these results prove robust for both relatively high noise regimes and when applied to biophysically realistic spiking neuron models, and further match experimental recordings from acute brain slices.
A Framework for

In this paper, we are proposing a framework of systematic process safety evaluation, design and operation management. The current safety design seems to be done using heuristics and experiences of process designers and safety engineers. Because of this, the quality of safety design is heavily dependent on the expertise of those engineers. The proposed framework expresses the process as a design of independent protection layer (IPL). A scenario-based approach is introduced to the hazard analysis and the design of ILP 3, 4 and 5 to support utilization of design rationales. The proposed framework is presented using the IDEF0 activity model, so that all the inputs, outputs, controls, and mechanisms to achieve particular activities in designing safety can be expressed explicitly.

Impediments to the Success of Management Actions for Species Recovery

Finding cost-effective management strategies to recover species declining due to multiple threats is challenging, especially when there are limited resources. Recent studies offer insights into how costs and threats can influence the best choice of management actions. However, when implementing management actions in the real-world, a range of impediments to management success often exist that can be driven by social, technological and land-use factors. These impediments may limit the extent to which we can achieve recovery objectives and influence the optimal choice of management actions. Nonetheless, the implications of these impediments are not well understood, especially for recovery planning involving multiple actions. We used decision theory to assess the impact of these types of impediments for allocating resources among recovery actions to mitigate multiple threats. We applied this to a declining koala (Phascolarctos cinereus) population threatened by habitat loss, vehicle collisions, dog attacks and disease. We found that the unwillingness of dog owners to restrain their dogs at night (a social impediment), the effectiveness of wildlife crossings to reduce vehicle collisions (a technological impediment) and the unavailability of areas for restoration (a land-use impediment) significantly reduced the effectiveness of our actions. In the presence of these impediments, achieving successful recovery may be unlikely. Further, these impediments influenced the optimal choice of recovery actions, but the extent to which this was true depended on the target koala population growth rate. Given that species recovery is an important strategy for preserving biodiversity, it is critical that we consider how impediments to the success of recovery actions modify our choice of actions. In some cases, it may also be worth considering whether investing in reducing or removing impediments may be a cost-effective course of action.
Employment, Emerging Labor Markets, and the Role of Education in Rural China

The overall goal of this paper is to contribute to the ongoing assessment of China's rural labor markets. To meet this goal, we have three specific objectives. First, we will provide an update of the trends in off-farm labor participation and wages of the sample households and examine how labor market outcomes have changed for those with different levels of education. Second, we will then seek to examine if education in different time periods - the late 1980s, the early 1990s and the mid 1990s -- can be associated with increasing access to off-farm jobs. Finally, we will examine how returns to education have changed during the course of the reform era. In short, our hypotheses are that if labor markets are increasingly rewarding those with a. ) better education job access; b. ) easier entry; and c. ) higher wages, such outcomes will count as evidence that labor markets are improving. Both the descriptive data and the multivariate analysis robustly support the findings that between the late 1980s and the mid-1990s, labor markets have improved in the sense that rural workers have been increasingly rewarded for their education.
Complex Analysis and Operator Theory Dominated Compactness Theorem in Banach Function Spaces and its Applications

A famous dominated compactness theorem due to Krasnosel’skĭı states that compactness of a regular linear integral operator in L follows from that of a majorant operator. This theorem is extended to the case of the spaces L · (Ω, μ, ), μΩ < ∞, with variable exponent p( · ), where we also admit power type weights . This extension is obtained as a corollary to a more general similar dominated compactness theorem for arbitrary Banach function spaces for which the dual and associate spaces coincide. The result on compactness in the spaces L · (Ω, μ, ) is applied to fractional integral operators over bounded open sets. Mathematics Subject Classification (2000). Primary 47B07; Secondary 47B38.
In silico detection of tRNA sequence features characteristic to aminoacyl-tRNA synthetase class membership

Aminoacyl tRNA synthetases (aaRS) are grouped into Class I and II based on primary and tertiary structure and enzyme properties suggesting two independent phylogenetic lineages. Analogously, tRNA molecules can also form two respective classes, based on the class membership of their corresponding aaRS. Although some aaRS–tRNA interactions are not extremely specific and require editing mechanisms to avoid misaminoacylation, most aaRS–tRNA interactions are rather stereospecific. Thus, class-specific aaRS features could be mirrored by class-specific tRNA features. However, previous investigations failed to detect conserved class-specific nucleotides. Here we introduce a discrete mathematical approach that evaluates not only class-specific ‘strictly present’, but also ‘strictly absent’ nucleotides. The disjoint subsets of these elements compose a unique partition, named extended consensus partition (ECP). By analyzing the ECP for both Class I and II tDNA sets from 50 (13 archaeal, 30 bacterial and 7 eukaryotic) species, we could demonstrate that class-specific tRNA sequence features do exist, although not in terms of strictly conserved nucleotides as it had previously been anticipated. This finding demonstrates that important information was hidden in tRNA sequences inaccessible for traditional statistical methods. The ECP analysis might contribute to the understanding of tRNA evolution and could enrich the sequence analysis tool repertoire.
Comparing bare-hand-in-air Gesture and Object-in-hand Tangible User Interaction for Navigation of 3D Objects in Modeling

3D modeling is used in Computer Graphics in various fields. Since the growth of gestures, virtual reality and embodied cognition, there have been various new technologies developed to either improve the modeling efficiency, or to provide more nature intuitive experience to the users. In this paper, from the user experience perspective, we try to compare these methods for navigation of 3D objects in the virtual modeling environment including: simple bare hand gestures, tangible user interfaces (TUI) with object in hand, as well as mouse/keyboard as the primary input. Based on embodied cognition theory, we hypothesis that the object-in-hand method might bring better user experience since the interaction between the object and hand can enhance the user's cognition while navigating a model. We present a conceptual design, with two approaches and three design models which demonstrate differences in user interaction with 3D modeling software.
Food Allergy Readiness and Anaphylaxis Management in Early Childhood Education and Care in Western Australia

WITH THE INCREASE IN prevalence of food allergy (FA) in young children, early childhood education and care (ECEC) providers are likely to have more enrolments of children who are at risk of anaphylaxis. This study examines the status of FA management in ECEC, and assesses the services’ current readiness to prevent and manage FA. A cross-sectional study comprising an online survey with multiple-choice and open-ended questions was conducted with 53 long day care services in Western Australia. Among the respondents, 83 per cent of services had at least one child enrolled with FA, 96 per cent had an FA policy, and 91 per cent required staff to undertake anaphylaxis training. A high level of self-reported confidence and skills were demonstrated; however, gaps were identified in risk-minimisation knowledge, use of adrenaline (epinephrine) autoinjectors and available resources. Extensive promotion of available resources will help improve compliance with anaphylaxis guidelines.
