Metaphors as Proxies for Identity: A Case Study of a Teaching English to Young Learners (TEYL) Teacher

Metaphor and metaphorical expressions are phenomena of interest in teacher education research and research on teacher identity. However, little attention has been given to teaching of English to young learners (TEYL) teachers’ metaphorical expressions, and what these expressions might tell us about their identities and experiences. This study explores the metaphorical expression constructed by an experienced teacher to describe what it means to be a TEYL teacher in the ESL context. Data were gathered from semi-structured interviews, stimulated recall interviews, and a metaphor elicitation prompt: ‘Who do you see yourself as a teacher? ’ The results revealed that while the metaphorical expression of ‘mother’ stands out as a concept that associates teaching with being nurturing, the teacher’s enactment of other roles ; projected as ‘knowledge provider’, ‘law enforcer’, and ‘facilitator’ , is more strongly oriented to the behaviourist idea of teaching. These findings shed light on the role of identity in expanding the in-service teachers’ perspective of teachers and teaching using self-constructed metaphors. A major recommendation of this study is that teacher educators need to promote reflective practice in TESL teacher training to critically explore the concept of knowledge about self.

How far do shocks move across borders? Examining volatility transmission in major agricultural futures markets

This paper examines the level of interdependence and volatility transmission in global agricultural futures markets. We follow a multivariate GARCH approach to explore the dynamics and cross-dynamics of volatility across major exchanges of corn, wheat, and soybeans between the United States, Europe, and Asia. We account for the potential bias that may arise when considering exchanges with different closing times. The results indicate that agricultural markets are highly interrelated and there are both own- and cross- volatility spillovers and dependence among most of the exchanges. The results also show the major role Chicago plays in terms of spillover effects over the other markets, particularly for corn and wheat. Additionally, the level of interdependence between exchanges has only increased in recent years for some of the commodities.
Central Pattern Generator Based Omnidirectional Locomotion for Quadrupedal Robotics

Abstract : Trajectory generation for quadruped robots is a challenging task since they are underactuated systems which must balance using sensory feedback and satisfy ground contact constraints. There is a substantial body of evidence that many animals use central pattern generators (CPGs) for generating joint trajectories and regulation through sensory feedback. However, CPG models formulated in the joint space do not explicitly formulate or account for ground contact constraints especially during turning which can introduce foot slip in the gait. Task-based CPGs offer several advantages in that they can explicitly satisfy ground contact constraints, and we suggest an approach to generating foot velocity controls in the body frame to enable omnidirectional locomotion.
A Quantitative Measurement for Reputation of Web Service and Providers Based on Cloud Model

Quality of Web service, especially the reputation, has become a benchmark to differentiate the services and providers. Unfortunately, the current reputation research in the field of Web services don't reasonably and correctly think about the randomicity and fuzziness which has been the basic issue in the relative research area about trust. We proposed two novel metrics to qualify the reputation of Web services and providers. We designed two kinds of trust model based on cloud model theory to describe the randomicity and fuzziness of the two metrics. Furthermore, a formalized calculation was provided to obtain the trust degree of services requestors to Web services and providers.
Multilingual education in South Africa: the role of publishers

Abstract The South African constitution and related legislative tools provide a supportive framework for multilingual education. Successful implementation, however, requires appropriate learning materials and questions remain as to the vision and commitment of publishers to producing them. Based on an analysis of currently available books for children and interviews with publishers and key figures in the book value chain, this paper explores both the educational rationale for African language publishing and the issues that constrain expansion. These issues include the heavy dependence on the schools market in a society where the majority of the population cannot or do not buy books, the consequences of the slow implementation of the government language-in-education policy, and the particular challenges faced by small publishers. It argues that in order to move beyond dependence on the schools market, publishers need to look critically at the content of the materials they are producing, methods of reaching the huge, untapped markets, and pricing strategies. It also considers differing opinions about the usefulness of translation in increasing the amount of reading material in African languages. Finally, it concludes that responsibility for finding a way out of the current impasse lies with both government and the publishing industry.
Preoperative Periarticular Knee Bone Mineral Density in Osteoarthritic Patients Undergoing TKA

Background: Preoperative periarticular bone quality is affected by joint loading. The purpose of this study was to determine the periarticular bone mineral density of the knee joint of patients undergoing total knee arthroplasty, and whether the location of the load-bearing axis correlates with the measured bone mineral density. Materials and Methods: The bone mineral densities of the medial and lateral femoral condyles and the medial and lateral tibial condyles were analyzed in consecutive 116 osteoarthritic patients (130 knees) by dual energy x-ray absorptiometry. Results: The median bone mineral density values in the condyles were 1.138 in femoral medial, 0.767 in femoral lateral, 1.056 in tibial medial, and 0.714 in tibial lateral. The medial condyles showed significantly higher bone mineral densities than the lateral condyles in both the femur and tibia. In addition, the femoral medial showed significantly higher bone mineral density levels than the tibial medial, and the femoral lateral condyle had higher bone mineral density levels than the tibial lateral. The bone mineral density Medial/Lateral ratio was significantly negatively correlated with the location (tibial medial edge 0%, lateral edge 100%) of the load-bearing axis in the femur and tibia. Conclusion: Preoperative bone mineral density values may provide against the changes in bone mineral density after total knee arthroplasty by reflecting the correlation with joint loading axis. These results help explain why total knee arthroplasty has such good long-term clinical outcomes with a low frequency of component loosening and periarticular fractures despite a high degree of postoperative bone loss.
Identification of therapeutic targets in ovarian cancer through active tyrosine kinase profiling

The activation status of a set of pro-oncogenic tyrosine kinases in ovarian cancer patient samples was analyzed to define potential therapeutic targets. Frequent activation of HER family receptor tyrosine kinases, especially HER2, was observed. Studies in ovarian cancer cell lines confirmed the activation of HER2. Moreover, knockdown of HER2 caused a strong inhibition of their proliferation. Analyses of the action of agents that target HER2 indicated that the antibody drug conjugate trastuzumab-emtansine (T-DM1) caused a substantial antitumoral effect in vivo and in vitro, and potentiated the action of drugs used in the therapy of ovarian cancer. T-DM1 provoked cell cycle arrest in mitosis, and caused the appearance of aberrant mitotic spindles in cells treated with the drug. Biochemical experiments confirmed accumulation of the mitotic markers phospho-Histone H3 and phospho-BUBR1 in cells treated with the drug. Prolonged treatment of ovarian cancer cells with T-DM1 provoked the appearance of multinucleated cells which later led to cell death. Together, these data indicate that HER2 represents an important oncogene in ovarian cancer, and suggest that targeting this tyrosine kinase with T-DM1 may be therapeutically effective, especially in ovarian tumors with high content of HER2.
Parental intervention style and adult sibling conflicts: The mediating role of involvement in sibling bullying

Managing conflicts and aggressive behaviors between siblings is challenging for many parents, and parental responses to sibling conflict has been shown to influence the quality of children’s sibling interactions. Building on previous work on parental involvement in sibling conflict, the aim of this study was to investigate the mediating role of sibling bullying perpetration and victimization during childhood and adolescence in the relationship between parental intervention styles and conflicts in young adults’ sibling relationships. A sample of 302 individuals aged 17–33 years participated in the study. Results of structural equation modeling confirmed the proposed mediation model of young adults’ sibling conflicts. More precisely, parental control and parental noninvolvement were positively associated with experiences of sibling bullying perpetration and victimization, whereas parental coaching was associated with lower reports of sibling victimization. Involvement in sibling bullying during childhood and adolescence was, for its part, associated with sibling conflicts in young adulthood. Results of the current study confirmed that parenting intervention styles can influence children’s involvement in sibling bullying, which in turn, can predict conflicts in adult sibling relationships. In line with the family system theory, these results underline that parents can inadvertently play a role in the development of dysfunctional sibling relationships.
A case for in-kernel data streaming over the file subsystem

This paper maeks a case for a new implementation of in-kernel data streaming in Unix. In particular, we show we can use it to improve the throughput during an important activity: le transfer. The performance improvements are not limited to the aggregate throughput of the system, and we see that it makes lesser demands on the system. This note describes the performance measurements of our implementation of in-kernel data streaming in Unix for large le transfers, and presents a comparison with standard user driven transfers.
Executive control is a positive predictor of treatment maintenance following anomia therapy

Background: Aphasia, a difficulty producing or understanding language, affects roughly 35% of stroke survivors and is associated with more severe disability and poorer functional outcomes than other stroke-related deficits. Ample evidence exists in support of the efficacy of aphasia treatment, even in the chronic stages of recovery. Evidence regarding the optimal predictors of aphasia recovery, however, remains mixed. Many potential predictors of language recovery post-stroke have been proposed; however, treatment outcomes vary, even among individuals with similar demographic and linguistic profiles undergoing similar treatments. Recent findings suggest that neuropsychological factors, such as EC, may play a crucial role in language recovery post-stroke (Lambon Ralph, Snell, Fillingham, Conroy, & Sage, 2010). EC enables individuals to perform goal-oriented behaviours and navigate novel situations. While some posit that EC is a unitary, undifferentiated director of behaviour, others suggest it is composed of multiple distinguishable processes. There is evidence (Miyake et al., 2000) for both the unity and diversity of EC, suggesting three separable EC processes that are linked by an underlying common EC factor; these are: (i) inhibition of distracting information, (ii) shifting among task-sets, and (iii) updating working memory contents. Although EC is increasingly emerging as an important predictor of aphasia recovery (Simic, Rochon, Greco, & Martino, 2017), it is based on a broad range of treatment approaches and EC measures; importantly, existing evidence has not used theoretical frameworks to measure EC. Consequently, it remains difficult to distinguish how EC supports aphasia treatment outcomes. Aims: The aim of this study was to apply Miyake and colleagues’ framework of EC (Miyake et al., 2000) to determine whether the three core EC processes of inhibition, shifting, and updating are good predictors of treatment gains, maintenance and generalization, following a structured naming therapy protocol, the Phonological Components Analysis (PCA) treatment (Leonard et al., 2015).
How to understand the cell by breaking it – methods and software for network analysis of gene perturbation screens

[2] How to understand a complex system? Physicist Richard Feynman once said: "What I cannot create, I do not understand". This quote stresses the importance of action for understanding. A complex system is not understood solely by passive contemplation, it needs active manipulation by the researcher. In biology this fact is long known. Functional genomics has a long tradition of inferring the inner working of a cell by breaking it. "What I cannot break, I do not understand" is the credo of functional genomics research.

Decentralized Radio Resource Allocation for Single-Network and Multi-Homing Services in Cooperative Heterogeneous Wireless Access Medium

This paper studies radio resource allocation for mobile terminals (MTs) in a heterogeneous wireless access medium. Unlike the existing solutions in literature, we consider the simultaneous presence of both single-network and multi-homing services in the networking environment. In single-network services, an MT is assigned to the best wireless access network available at its location. On the other hand, in multi-homing services, an MT utilizes all available wireless access networks simultaneously. The objective of the radio resource allocation is of twofold: to determine the optimal assignment of MTs with single-network service to the available wireless access networks, and to find the corresponding optimal bandwidth allocation to the MTs with single-network and multi-homing services. We develop a sub-optimal decentralized implementation of the radio resource allocation, which relies on network cooperation to perform the allocation in a dynamic environment in an efficient manner. The MT plays an active role in the resource allocation operation, whether by selecting the best available wireless network for single-network services or by determining the required bandwidth share from each available network for multi-homing services. Simulation results are presented to demonstrate the performance of the proposed algorithm.

The predictive coding model of perception proposes that neuronal responses are modulated by the amount of sensory input that the internal prediction cannot account for (i.e., prediction error). However, there is little consensus on what constitutes nonpredicted stimuli. Conceptually, whereas mispredicted stimuli may induce both prediction error generated by prediction that is not perceived and prediction error generated by sensory input that is not anticipated, unpredicted stimuli involves no top-down, only bottom-up, propagation of information in the system. Here, we examined the possibility that the processing of mispredicted and unpredicted stimuli are dissociable at the neurophysiological level using human electroencephalography. We presented participants with sets of five tones in which the frequency of the fifth tones was predicted, mispredicted, or unpredicted. Participants were required to press a key when they detected a softer fifth tone to maintain their attention. We found that mispredicted and unpredicted stimuli are associated with different amount of cortical activity, probably reflecting differences in prediction error. Moreover, relative to predicted stimuli, the mispredicted prediction error manifested as neuronal enhancement and the unpredicted prediction error manifested as neuronal attenuation on the N1 event-related potential component. These results highlight the importance of differentiating between the two nonpredicted stimuli in theoretical work on predictive coding.
New Variation of Constants Formula for Some Partial Functional Differential Equations with Infinite Delay

In this work, we give a new variation of constants formula for some partial functional differential equations with infinite delay. We assume that the linear part is not necessarily densely defined and satisfies the known Hille-Yosida condition. When the phase space is a uniform fading memory space, we establish a spectral decomposition of the phase space. This allows us to study the existence of almost periodic solutions when the equation has a bounded solution on the half line $\mathbb{R}^+$
Bandwidth Enhancement of 4 $\,\times\,$4 Butler Matrix Using Broadband Forward-Wave Directional Coupler and Phase Difference Compensation

A broadband Butler matrix by combining the proposed broadband forward-wave directional coupler and a broadband middle network is proposed. Test samples of both the proposed coupler and Butler matrix are fabricated on Ro4003 and the sizes are 0.4 λ<sub>g</sub> × 0.14 λ<sub>g</sub> and 1.02 λ<sub>g</sub> × 1.17 λ<sub>g</sub>, respectively. For the Butler matrix, the amplitudes of the output signals and the phase imbalances between output ports can be kept at an approximately constant level. The errors of phase imbalances can be kept within ±6<sup>°</sup> from 1.96 GHz to 3.15 GHz and the corresponding fractional bandwidth is 47%.
Supporting understanding of students learning via visual self-assessment

Understanding students’ learning is crucial to the development of teaching. The most common systematic approach to understanding students’ learning has been summative course feedback, gathered after each course. However, students do not seem to be motivated to give this summative feedback after courses, with answer rates as low as 30 percent at Aalto University. Based on our observations, this is partly due to the timing and quality of current methods: students do not themselves benefit from any possible developments to the course. We soon realised that we merely need to develop a more dynamic culture of giving feedback during a course and started a project called Dynamic Course and Programme Level Feedback. We use a concept mapping tool to collect data from students during a course. This data is then visualised as dashboards that serve as feedback for teachers and enable adaptive teaching.
Contribution of the Plasmalemma to Ca2+ Homeostasis in Hair Cells

Calcium influx through transduction channels and efflux via plasmalemmal Ca2+-ATPases (PMCAs) are known to contribute to calcium homeostasis and modulate sensory transduction in vertebrate hair cells. To examine the relative contributions of apical and basolateral pathways, we analyzed the calcium dynamics in solitary ciliated and deciliated guinea pig type I and type II vestibular hair cells. Whole-cell patch-clamp recordings demonstrated that these cells had resting potentials near −70 mV and could be depolarized by 10–20 mV by superfusion with high potassium. Fura-2 measurements indicated that ciliated type II cells and deciliated cells of either type had low basal [Ca2+]i, near ∼90 nm, and superfusion with high potassium led to transient calcium increases that were diminished in the presence of Ca2+ channel blockers. In contrast, measurements of type I ciliated cells, hair cells with large calyceal afferents, were associated with a higher basal [Ca2+]iof ∼170 nm. High-potassium superfusion of these cells induced a paradoxical decrease in [Ca2+]i that was augmented in the presence of Ca2+ channel blockers. Optical localization of dihydropyridine binding to the kinocilium suggests that they contain L-type calcium channels, and as a result apical calcium influx includes a contribution from voltage-dependent ion channels in addition to entry via transduction channels localized to the stereocilia. Eosin block of PMCA significantly altered both [Ca2+]i baseline and transient responses only in ciliated cells suggesting that, in agreement with immunohistochemical studies, PMCA is primarily localized to the bundles.

A Framework for Semantics of UML Sequence Diagrams in PVS

This paper presents a framework for representing formal semantics of a subset of the Unified Modeling Language (UML) notation in a higher-order logic, more specifically semantics of UML sequence diagrams is encoded into the Prototype Ver- ification System (PVS). The primary objective of our work is to make UML models amenable to rigorous analysis by providing their precise semantics. This approach paves a way for formal development of systems through a systematic transformation of UML models. This work is a part of a long-term vision to explore how the PVS tool set can be used to underpin practical tools for analyzing UML models. It contributes to the ongoing effort to provide mathematical foundation to UML notations, with the aim of clarifying the semantics of the language as well as supporting the development of semantically-based tools.
Three birds (in the LOD cloud) with one stone: BabelNet, Babelfy and the Wikipedia Bitaxonomy!

In this paper we present the current status of linguistic resources published as linked data in the LLOD cloud in our research group, namely BabelNet, Babelfy and the Wikipedia Bitaxonomy. We describe the diﬀerent resources in terms of their salient aspects, objectives and expected output and discuss the beneﬁts that each of these resources potentially brings in the world of LLOD NLP-aware services. We also present public web-based services which allow to query, explore and export data into RDF format, thus truly enabling interoperability across the web.
