Going Down the Rabbit-hole: Teachers’ Engagements with ‘Dialectical Images’ in Canadian Children’s Literature on Social Justice

This article explores the attraction of Canadian elementary teachers to children’s stories that narrate trauma, particularly the trauma associated with First Nations peoples’ experiences in Canadian residential schools as told by Indigenous authors. The teachers’ responses to these texts are conceived of as occurring within a ‘contact zone,’ situated between dominant white culture (the culture shared by the teachers) and the historically marginalized cultures represented in the stories. An interpretative lens of critical nostalgia is developed, placing the question of contact zones within the context of memory studies, trauma studies, curriculum theory and critical pedagogies related to remembrance. The paper identifies the need for developing critical nostalgia as a productive form of pedagogical remembrance, drawing on Roger Simon’s adaptation to an educational context of Walter Benjamin’s notion of the dialectical image.
Critical Analysis of CLIL: Taking Stock and Looking Forward

The growing interest in Content and Language Integrated Learning (CLIL) has resulted in enthusiasm in and active pursuit of improved methods of foreign/second-language (L2) teaching in Europe. However, the definition and scope of the term CLIL both internally, as used by CLIL advocates in Europe, and externally, as compared with immersion education in and outside Europe, indicate that the core characteristics of CLIL are understood in different ways with respect to: the balance between language and content instruction, the nature of the target languages involved, instructional goals, defining characteristics of student participants, and pedagogical approaches to integrating language and content instruction. We argue further that attempts to define CLIL by distinguishing it from immersion approaches to L2 education are often misguided. The aim of this article is to examine these ambiguities and to call for clarification of the definition of CLIL. Clarification is critical if CLIL is to evolve and improve systematically and if CLIL educators are to benefit from the experiences and knowledge acquired in other educational settings.
ConceptCloud: a tagcloud browser for software archives

ConceptCloud is an interactive browser for SVN and Git repositories. Its main novelty is the combination of an intuitive tag cloud interface with an underlying concept lattice that provides a formal structure for navigation. This combination allows users to explore repositories serendipitously, without predefined search goals and along different navigation paths. ConceptCloud can derive different lattice types for a repository and supports concurrent navigation in multiple linked tag clouds that can each be individually customized, which allows multi-faceted repository explorations.
Bifurcation Analysis of the Quasi-periodic Solution with Three-Phase Synchronized Envelopes in a Ring of Three-Coupled, Bistable oscillators

In this study, we investigate the bifurcation of the quasi-periodic solution in a ring of three-coupled, bistable oscillators. The quasi-periodic solution under study is a propagating wave solution with three-phase synchronized envelope, and we name it "ICC3ϕ" which means invariant closed curve for which time waveforms have three-phase synchronized envelope. We obtain the two-parameter bifurcation diagram of ICC3ϕ with respect to the coupling factor α versus the nonlinear strength ϵ. Consequently, we detect several Arnold tongues showing various periodic solutions of ICC3ϕ. By investigating the bifurcation on the boundary of these Arnold tongues, we clarify the transition from periodic to quasi-periodic solution of ICC3ϕ or the inverse. Specifically, the transition of the period-4, period-5, and period-7 solutions to ICC3ϕ is due to a saddle-node bifurcation, which has no hysteresis. In contrast, the transition from the period-3 solution to ICC3ϕ is a combination of subcritical pitchfork and heteroclinic bifurcations; hence, it has hysteresis. We draw diagrams showing the connection of unstable manifolds of heteroclinic bifurcation.
A Stochastic Network Under Proportional Fair Resource Control - Diffusion Limit with Multiple Bottlenecks

We study a multiclass stochastic processing network operating under the so-called proportional fair allocation scheme, and following the head-of-the-line processor-sharing discipline. Specifically, each server's capacity is shared among the job classes that require its service, and it is allocated, in every state of the network, among the first waiting job of each class to maximize a log-utility function. We establish the limiting regime of the network under diffusion scaling, allowing multiple bottlenecks in the network, and relaxing some of the conditions required in prior studies. We also identify the class of allocation schemes among which the proportional fair allocation minimizes a quadratic cost objective function of the diffusion-scaled queue lengths, and we illustrate the limitation of this asymptotic optimality through a counterexample.
Tightly Cooperative Caching Approach in Mobile Ad Hoc Network

Mobile Ad hoc Network (MANETs) relies on cooperation of all participating nodes. All mobile nodes may easily vulnerable to selfish/malicious nodes which can lower down data communication and degrade the network performance due to refusal of relaying packet in order to save their own resources such as power, time, etc. These non-cooperative behaviors become challenging in cooperative caching system which mainly depends on cooperative nodes. To solve this problem, we propose tightly cooperative caching approach (TCCA) to encourage all nodes to aggressively cooperate by using enhanced credit-based distribution algorithm based on the resource status of the mobile nodes and the demand volume of the request to have load balancing among the acceptor nodes and requester nodes. According to the experimental results, our approach gets the superior results than other approaches under different parameter setting of nodes and network structure. Key-Words: mobile ad hoc network, cooperative caching, credit-based distribution, load balancing
Correlatos entre o perfil comunicativo e adaptação sócio-comunicativa no espectro autístico

OBJETIVO: verificar se ha correlacoes significativas entre os dados referentes ao perfil funcional da comunicacao e os dados da adaptacao socio-comunicativa obtidos por meio de entrevistas individuais com os pais e as terapeutas de criancas com Disturbios do Espectro Autistico. METODOS: foram sujeitos deste estudo 48 criancas, com diagnostico clinico incluido no espectro autistico com os quais foram coletados os dados para a determinacao do perfil funcional da comunicacao por meio de situacao ludica, buscando a espontaneidade comunicativa. Participaram ainda, os responsaveis, legais e pelo atendimento fonoaudiologico especializado, das 48 criancas, ou seja, 46 maes e dois pais e 15 terapeutas, respondendo individualmente a um questionario sobre o relacionamento social das criancas citadas. RESULTADOS: pode-se observar que os resultados referentes a adaptacao socio-comunicativa obtida a partir de entrevistas com terapeutas e pais apresentaram correlacoes significativas com o perfil funcional da comunicacao. De forma geral, o estudo das correlacoes entre os aspectos do perfil comunicativo e da adaptacao socio-comunicativa nao apresentou um grande numero de correlacoes, sendo este numero ainda menor quando os pais foram os informantes, demonstrando a interdependencia das areas estudas. CONCLUSAO: uma das maiores evidencias deste trabalho e que mesmo que as criancas do espectro autistico apresentem um desenvolvimento deficitario das habilidades de linguagem, cognicao e socializacao, ainda assim elas sao capazes de extrair pistas linguisticas e nao-linguisticas do meio comunicativo, e utiliza-las de forma contextual em sua vida social, associando-as com os ganhos na linguagem e no desempenho socio-cognitivo.
Leakage power reduction in multicore chips via online decap modulation

The decap leakage constitutes a significant part of total leakage in multicore processors. Leaking decap is widely used in chips to provide transient power to function blocks, and the amount of decap placed over multicore chip is determined by the worst case at design time. Considering that the decaps do not have to be kept 100% "on" when the chip is running workloads, in this paper we propose an ideal online approach to adapt the percentage of "on" capacitance in the decaps to the dynamic need of the core loads, and therefore to reduce the leakage power consumption in the chip. Our approach is based on the equivalent resistance model of the power sources (power supply pins and local decaps) and the core loads, and a novel fast algorithm is developed to determine the required amount of decap at runtime. Results on a set of multicore test cases show that our approach can achieve up to 48% saving in decap leakage.
Identification in the mould Hypocrea jecorina of a gene encoding an NADP+: d-xylose dehydrogenase

A gene coding for an NADP+-dependent d-xylose dehydrogenase was identified in the mould Hypocrea jecorina (Trichoderma reesei). It was cloned from cDNA, the active enzyme was expressed in yeast and a histidine-tagged enzyme was purified and characterized. The enzyme had highest activity with d-xylose and significantly smaller activities with other aldose sugars. The enzyme is specific for NADP+. The Km values for d-xylose and NADP+ are 43 mM and 250 μM, respectively. The role of this enzyme in H. jecorina is unclear because in this organism d-xylose is predominantly catabolized through a path with xylitol and d-xylulose as intermediates and the mould is unable to grow on d-xylonic acid.

GPi Oscillatory Activity Differentiates Tics from the Resting State, Voluntary Movements, and the Unmedicated Parkinsonian State

Background: Deep brain stimulation (DBS) is an emerging treatment strategy for severe, medication-refractory Tourette syndrome (TS). Thalamic (Cm-Pf) and pallidal (including globus pallidus interna, GPi) targets have been the most investigated. While the neurophysiological correlates of Parkinson's disease (PD) in the GPi and subthalamic nucleus (STN) are increasingly recognized, these patterns are not well characterized in other disease states. Recent findings indicate that the cross-frequency coupling (CFC) between beta band and high frequency oscillations (HFOs) within the STN in PD patients is pathologic. Methods: We recorded intraoperative local field potentials (LFPs) from the postero-ventrolateral GPi in three adult patients with TS at rest, during voluntary movements, and during tic activity and compared them to the intraoperative GPi-LFP activity recorded from four unmedicated PD patients at rest. Results: In all PD patients, we noted excessive beta band activity (13–30 Hz) at rest which consistently modulated the amplitude of the co-existent HFOs observed between 200 and 400 Hz, indicating the presence of beta-HFO CFC. In all 3TS patients at rest, we observed theta band activity (4–7 Hz) and HFOs. Two patients had beta band activity, though at lower power than theta oscillations. Tic activity was associated with increased high frequency (200–400 Hz) and gamma band (35–200 Hz) activity. There was no beta-HFO CFC in TS patients at rest. However, CFC between the phase of 5–10 Hz band activity and the amplitude of HFOs was found in two TS patients. During tics, this shifted to CFC between the phase of beta band activity and the amplitude of HFOs in all subjects. Conclusions: To our knowledge this is the first study that shows that beta-HFO CFC exists in the GPi of TS patients during tics and at rest in PD patients, and suggests that this pattern might be specific to pathologic/involuntary movements. Furthermore, our findings suggest that during tics, resting state 5–10 Hz-HFO CFC shifts to beta-HFO CFC which can be used to trigger stimulation in a closed loop system when tics are present.
Transparent acceleration of data dependent instructions for general purpose processors

Although transistor scaling keeps following Moore’s law, and more area is available for designers, the clock frequency and ILP rate do not present the same level of growth anymore. This way, new architectural alternatives are necessary. Reconfigurable fabric appears to be one emerging possibility: besides exploiting the parallelism among instructions, it can also accelerate sequences of data dependent ones. However, coarse grain reconfiguration wide spread usage is still withhold by the need of special tools and compilers, which clearly do not sustain the reuse of legacy code without any modification. Based on all these facts, this work proposes a new Binary Translation algorithm, implemented in hardware and working in parallel to the processor, responsible for transforming sequences of instructions at run-time to be executed on a dynamic coarse-grain reconfigurable array, tightly coupled to a traditional RISC machine. Therefore, we can take advantage of using pure combinational logic to optimize even control-flow oriented code in a totally transparent process, without any modification in the source or binary codes. Using the Simplescalar Toolset together with the embedded benchmark suite MIBench, we show performance improvements and area evaluation when comparing against traditional superscalar architectures.
Addiction as a complex social process: An action theoretical perspective

This article introduces an action theoretical perspective of addiction. The view that addiction resides solely within the individual continues to foster significant limitations across addiction theorizing, research, and treatment. Exclusive focus on an individual neurobiological level of analysis precludes important additional layers of understanding, for example, the roles of individual and joint human actions, the socially constituting processes of addiction, and the role of gender. Our perspective is that a neurobiological view on addiction is insufficient without consideration of goals, intentionality, relationships, and meaning. Using a composite case scenario, we offer an action theoretical framework for understanding individual and joint addiction processes over time and within the context of other life processes. This integrative framework considers manifest behaviors, internal and communicative processes, and the social meaning of addiction. This article offers a practical application of the theory and draws broad implications for the conceptualization and subsequent language of addiction.
Mixed Logical and Probabilistic Reasoning for Planning and Explanation Generation in Robotics

Robots assisting humans in complex domains have to represent knowledge and reason at both the sensorimotor level and the social level. The architecture described in this paper couples the non-monotonic logical reasoning capabilities of a declarative language with probabilistic belief revision, enabling robots to represent and reason with qualitative and quantitative descriptions of knowledge and degrees of belief. Specifically, incomplete domain knowledge, including information that holds in all but a few exceptional situations, is represented as a Answer Set Prolog (ASP) program. The answer set obtained by solving this program is used for inference, planning, and for jointly explaining (a) unexpected action outcomes due to exogenous actions and (b) partial scene descriptions extracted from sensor input. For any given task, each action in the plan contained in the answer set is executed probabilistically. The subset of the domain relevant to the action is identified automatically, and observations extracted from sensor inputs perform incremental Bayesian updates to a belief distribution defined over this domain subset, with highly probable beliefs being committed to the ASP program. The architecture's capabilities are illustrated in simulation and on a mobile robot in the context of a robot waiter operating in the dining room of a restaurant.
DNA methylation, insulin resistance and second-generation antipsychotics in bipolar disorder.

AIMS This study aimed to assess the effect of second-generation antipsychotic (SGA) use and insulin resistance on a global measure of DNA methylation in patients diagnosed with bipolar disorder. MATERIALS & METHODS Subjects stable on medication (either mood stabilizer monotherapy or adjuvant SGAs) were assessed for insulin resistance. Global methylation levels were assessed in leukocyte DNA from whole blood using the Luminometric Methylation Assay. Multivariable linear regression was used to investigate the effect of insulin resistance and SGA use on DNA methylation. RESULTS A total of 115 bipolar I subjects were included in this study. The average age was 43.1 ±12.2 years and 73% were on SGAs. Average% global methylation was 77.0 ± 3.26 and was significantly influenced by insulin resistance, SGA use and smoking. CONCLUSION This is the first study to show a relationship between SGA use, insulin resistance and global DNA methylation. Further work will be needed to identify tissue- and gene-specific methylation changes.
Epigenetic inactivation of tumour suppressor coding and non-coding genes in human cancer: an update

Cancer cells undergo many different alterations during their transformation, including genetic and epigenetic events. The controlled division of healthy cells can be impaired through the downregulation of tumour suppressor genes. Here, we provide an update of the mechanisms in which epigenetically altered coding and non-coding tumour suppressor genes are implicated. We will highlight the importance of epigenetics in the different molecular pathways that lead to enhanced and unlimited capacity of division, genomic instability, metabolic shift, acquisition of mesenchymal features that lead to metastasis, and tumour plasticity. We will briefly describe these pathways, focusing especially on genes whose epigenetic inactivation through DNA methylation has been recently described, as well as on those that are well established as being epigenetically silenced in cancer. A brief perspective of current clinical therapeutic approaches that can revert epigenetic inactivation of non-coding tumour suppressor genes will also be given.
Nature or nurture: are therapists born or trained?

A great deal of time, effort and money is involved in the training of counsellors; hence it is most important that the selection process discriminates between those candidates who are likely to achieve the standard required at the end of the training and those who are not. This paper discusses some of the issues pertinent to the selection of candidates for training as counsellors. It considers the question of whether counsellors are born or made, in other words whether anyone can be a good counsellor given the right training or whether they have to be suitable before they start. The paper uses Kohutian concepts to address issues of narcissism, as well as considering equal opportunities and personal development.
Shoe preference based on subjective comfort for walking and running.

BACKGROUND Subjective comfort of footwear is important for shoe and orthosis design. This study compared shoe preferences between walking and running, using subjective comfort as an outcome tool. METHODS Forty-one participants walked and ran 20 times each along a runway in three types of footwear (cushioning, lightweight, and stability) and chose the model that they preferred most for walking and running separately based on subjective comfort. RESULTS More participants preferred the cushioning model (walking, 34%; running, 41%) or the lightweight model (walking, 44%; running, 41%) over the stability model (walking, 22%; running, 17%). χ² tests revealed no differences between walking and running, runners and nonrunners, and lighter and heavier individuals. Women were more likely (odds ratio = 4.09) to prefer the lightweight model, whereas men preferred the cushioning (odds ratio = 2.05) and stability (odds ratio = 3.19) models. Most participants (71%) chose the same model for both activities. CONCLUSIONS Shoe preference varies among individuals and is influenced by sex. Most people feel comfortable walking and running in the same shoe model.
Strategic Choice and the Nature of the Chinese Family Business: An Exploratory Study of the Hong Kong Watch Industry

This study examines the relationship between the nature of the Chinese Family Business (CFB) and the business strategies adopted, in the setting of the Hong Kong watch industry. The nature of the CFB is conceptualized and measured as a set of sub-dimensions, represented by continuous variables. It is hypothesized that ‘ CFBness’ is positively associated with ‘traditional’ business strategies, but inhibitive of ‘upgrading’. The results show that the hypotheses are partially supported. While the findings support the view that firms’ strategic choices are constrained by material and ideational influences in their environment, only a small proportion of the variation in business strategies is accounted for by ‘CFB-ness’, leaving ample room for human agency. Overall, the results support a ‘middle view’ between the deterministic and voluntaristic perspectives, whereby firms exercise strategic choice within an environment that predisposes, but does not fix, their behaviour.
Shades of White: White Kids and Racial Identities in High School

What does it mean to be young, American, and white at the dawn of the twenty-first century? By exploring this question and revealing the everyday social processes by which high school students define white identities, Pamela Perry offers much-needed insights into the social construction of race and whiteness among youth. Through ethnographic research and in-depth interviews of students in two demographically distinct U.S. high schools-one suburban and predominantly white; the other urban, multiracial, and minority white-Perry shares students' candour about race and self-identification. By examining the meanings students attached (or didn't attach) to their social lives and everyday cultural practices, including their taste in music and clothes, she shows that the ways white students defined white identity were not only markedly different between the two schools but were considerably diverse and ambiguous within them as well. Challenging reductionist notions of whiteness and white racism, this study suggests how we might go "beyond whiteness" to new directions in antiracist activism and school reform. Shades of White is emblematic of an emerging second wave of whiteness studies that focuses on the racial identity of whites. It will appeal to scholars and students of anthropology, sociology, and cultural studies, as well as to those involved with high school education and antiracist activities.
