Developing algebraic reasoning in primary school using a hanging mobile as a learning supportive tool / El desarrollo del razonamiento algebraico en educación primaria utilizando una balanza como herramienta de apoyo

Abstract In this study, we investigated the development of algebraic reasoning in 65 fifth-grade students who never had algebra instruction before. In the six-lesson teaching sequence on solving linear equations, a hanging mobile, a physical balance model, played the central role. We expected students’ perceptual-motor experiences with this hanging mobile to be beneficial for the development of their reasoning related to linear equation solving. To investigate how students’ reasoning developed, we analysed videos of classroom interactions, students’ written work during the lessons and students’ responses to lesson-specific assessment tasks. Our results reveal that students showed progress in their level of algebraic reasoning and in their writing down of strategies. While working with the hanging mobile, students applied algebraic strategies such as restructuring, isolation and substitution. They later used these algebraic strategies for solving linear equations in new contexts. This suggests that the experiences students gained in the embodied learning environment provided a basis for algebraic reasoning, which appeared to support them when solving systems of symbolically presented linear equations.

Saliency-driven single image haze removal method based on reliable airlight and transmission

Abstract. Haze removal has become an attractive topic in recent years and several dehazing methods are proposed. Dark channel prior (DCP) is one of the most effective dehazing approaches. However, when dealing with images containing large white objects, DCP often mistakes white objects for opaque haze. It will cause the airlight to be overestimated and the transmission to be underestimated, and thus the dehazing results have serious color distortion. In view of the above problem, saliency detection is introduced into haze removal to obtain better restored images in this paper. We first propose a method for reliable airlight estimation. Then, a saliency prior is presented for hazy images, which can distinguish white objects from dense haze by saliency detection. On the basis of saliency prior, both accurate airlight and a correct transmission map can be obtained from images containing large white objects, and finally these images can be restored successfully. The experimental results illustrate that our proposed method has great superiority in color recovery compared with other state-of-art methods when dealing with images containing large white objects.

Do Managers Pay CSR for Private Motivation? A Dividend Tax Cut Case in Korea

A CEO who has an opportunity to pursue his interest may sacrifice investors with inefficient investments such as overinvestment in corporate social responsibility (CSR). As prior researchers have suggested a possibility to detect the perk portion of CSR investment using the dividend tax cut event, we tested whether managers decreased CSR spending while accelerating dividend payouts during the Korean dividend tax cut of 2015. Consistent with the prior studies on the dividend tax cut, we discovered a pattern of incremental dividend increase for the companies of agency conflict measured by extreme CEO ownership. However, we failed to find any statistically significant simultaneous reduction in donations after 2015. This study does not provide evidence that investments in CSR of Korean firms are not due to CEOs’ personal interest-seeking. Instead, we showed that the dividend tax cut event may not work as a universally applicable quasi-experimental setting to detect management overinvestments in CSR.
THE RELATIONSHIP OF ENVIRONMENTAL MANAGEMENT ACCOUNTING, ENVIRONMENTAL STRATEGY AND MANAGERIAL COMMITMENT WITH ENVIRONMENTAL PERFORMANCE AND ECONOMIC PERFORMANCE

Nowadays, carbon and other ozone harming emanations are one of the fundamental drivers of this overshoot. In the light of this discussion, the current examination aims to investigate the relationship between accounting, management sand environment in realizing firm performance. In doing so, the current examination opted to inspect the critical relationship of environmental management accounting (EMA), environmental strategies (ENS) and managerial commitment (MAC) in driving firm performance. Given the concerns within the literature that environmental processing within organization enhance financial costs, the authors of the study are motivated to analyze the impact of the variables on both environmental and economic performance (ECP) of small medium enterprises in Indonesia. We apply novel partial least square structural equation modelling by collected the data from 317 respondents of different small and medium size enterprises of Indonesia. The results of SEM confirm that ECP and environmental performance (ENP) have significantly and positively impacted by ENS. The outcomes of partial least square structural equation modelling also indicate that economic and ENP has also positively and significantly impacted by the EMA. Finally, the results of partial least squares structural equation modeling also specified that ECP and ENP have significantly and positively affected by MAC.

The syntax-prosody interface: current theoretical approaches and outstanding questions

Abstract The syntax-prosody interface concerns the relationship between syntactic and prosodic constituent structure. This paper provides an overview of theoretical advances in research on the syntax-prosody interface. Current theoretical work is situated historically, and is framed in light of the central research questions in the field, including (a) to what extent prosodic structure can be used as a diagnostic for syntactic constituent structure, (b) the significance of recursion in prosodic theory, and (c) how mismatches between syntactic and prosodic constituent structure are modeled in different approaches to the syntax-prosody interface. The paper concludes with a discussion of the current state of the field and directions for future research.
Finding success with pedagogical innovation: A case from CSL teachers’ experiences with TBLT

This study uncovers the under-explored influences that encourage teachers to incorporate task-based language teaching (TBLT) for teaching Chinese as a second language, and the process of teachers’ pedagogical attempts at a Chinese university. Activity Theory (Engeström, 1987) was adopted as the conceptual framework. As a qualitative study, the analysis drew on data from interviews and classroom observations with eight teachers, and complemented by interviews with two directors and 17 students. The study reveals that teachers’ pedagogical practice results from a process of negotiating the possible pedagogical tools to reach their teaching objectives in their context of teaching. In particular, teachers depart from the traditional teaching approach to incorporate tasks as a personal initiative in response to the perceived challenges in the effort to achieve their objectives. The study argues that compared to the constraints from the local education context, teacher beliefs and knowledge play a more critical role in shaping the extent to which teachers choose to adopt TBLT, as teacher beliefs and knowledge directly creates tension between TBLT as a tool and the desired objectives. The study proposes that the Problem-Solving Model (Havelock, 1969) for introducing pedagogical change gives teachers agency and ownership over TBLT, which may serve as a possible direction for realizing the pedagogical innovation.
Struggling with distinction: How and why people switch between cultural hierarchy and equality

In research on cultural taste and distinction, inconsistent and ambivalent attitudes towards hierarchy versus equality have largely been ignored. This study shows, by means of in-depth interviews with 90 Dutch people on their own and others’ cultural tastes, that both a hierarchical and an egalitarian repertoire appear in people’s narratives, and that these repertoires are often used simultaneously. People still distinguish culturally from others, but not consistently and often reluctantly, as they morally object to high–low distinctions based on aesthetic evaluations at the same time. This article analyses both repertoires and explores when and how tensions between the two come forward. We interpret these tensions on the micro level of self-presentation and habitus, and on the macro level of changing structures of inequality and meritocratic ideas.
Mineralogy and Geochemistry of the High‐Cr Podiform Chromitite from the Cuobuzha Ophiolite, Yarlung Zangbo Suture Zone, Western Tibet, China: Implication for its Origin

The Cuobuzha high‐Cr chromitites in the western segment of Yarlung Zangbo Suture Zone of Tibet are mainly hosted in the harzburgites as massive type, which are characterized by high concentrations of platinum group elements (PGE) ranging from 380 to 577 ppb, and low Pd/Ir ratios (<0.1). In mid‐ocean ridge basalts (MORB)‐normalized spidergrams, chromites of the Cuobuzha chromitites are depleted in Al, Ga, V, Mg and Zn, and enriched in Mn and Cr, sharing similar patterns with those of ophiolitic boninites in the Bonin and Thetford Mines. Approximately 20 platinum group mineral (PGM) grains were discovered from the samples, including laurite, erlichmanite, Os‐Fe alloy, cuproiridsite, and irarsite. The PGM assemblages indicate that sulfur fugacity was initially low enough to allow the precipitation of Os‐Fe alloy and increased thereafter, with the fall in temperature. Primary Fe‐Ni and Fe‐Cr alloys, which are stable in a highly reduced environment, occur as inclusions within chromites or clinopyroxenes. Calculated results show that the parental magma has an intimate affinity with boninites. Based on our observations, a model is proposed wherein the Cuobuzha chromitites contain high‐pressure and low‐pressure chromites. Low‐pressure chromites were formed via reaction between boninitic melts and peridotites, during which the high‐pressure chromites hosting highly reduced minerals were mobilized by melts and were reallocated to podiform chromitites.
The Antecedent of Job Engagement towards the Job Embeddedness and Performance of Educational Staff in University

This study aims to determine the antecedent of job engagement towards job embeddedness and the working performance among the educational staffs of Sarjanawiyata Tamansiswa University. The research design can be categorized as ex-post facto with a correlational study that examines the relationship between each research variable. The research sample used 118 educational staff at Sarjanawiyata Tamansiswa University. The data analysis used the Structural Equation Modeling (SEM) technique by using Lisrel 8.50 software. The research finding revealed that job embeddedness had a positive influence on job engagement significantly. Job satisfaction showed a positive influence on job engagement significantly. However, the influence of job embeddedness on the performance of educational staffs in Sarjanawiyata Tamansiswa University was not proven. The influence of job embeddedness towards the performance will be stronger through job engagement. Job engagement indicated a positive influence on the performance among the educational staff of Sarjanawiyata Tamansiswa University.

A theatrical critique of resilience in culture

Discourses of resilience rose to prominence in the field of culture in the wake of the 2008 financial crisis. In this thesis, the history of discourses and practices of resilience will be examined in order to understand how and why resilience became important in the field. I will argue that resilience discourses and practices, which concern the management of crises and risks, legitimise and effect the subsumption of semi-marketised spheres of activity and production, including that of culture. The history of resilience in culture will also reveal that its discourses and practices bear a close relationship to ecological rationales and environmental concerns. After performing a critique of dominant liberal resilience discourses and practices in cultural policy and administration through a reference to Yúdice’s idea of ‘culture-as-resource’, I examine alternative resiliences in art and culture using Balibar’s notion of ‘civility’. I argue that these alternatives are more explicitly concerned with limiting the reproduction of extremes of violence tied to an intensified subsumption of culture and the different historical crises of capitalism (socio-economic and environmental). Finally, I explore the extent to which art conceived in a post-Adornoian fashion negates the subsumption that resilience discourses legitimise and that resilience practices effect, on account of its capacity to theatrically present capitalism’s transgression of the social limits of the market (subsumption). This idea of art will complement the discussion of civility and will be contrasted to the ideologically legitimasing or what I call, after Marcuse, the ‘affirmative’ role that art plays in relation to economic and political power. The main contribution to knowledge I make in this thesis is to recontextualise current critiques of resilience in culture and to offer a field-specific framework for this critique, which also contributes to recodify recent debates about art, performance and neoliberalism in the UK, notably through an integration of environmental perspectives. Finally, this research also contributes to clarifying the scope of practical and cultural materialist methodology in performance research. It does so by offering a critique of a policy rationale through art and criticism conceived as post-romantic and conceptual practices.
The Barriers and Facilitators to the Implementation of Interventions for Children with Visual Impairments, Their Parents/Guardians or Educators: A Systematic Scoping Review

ABSTRACT A body of research indicates the importance of interventions for promoting the development and progress of children with visual impairments. However, the research available on suitable interventions for this population is relatively sparse. The purpose of this review is to identify, collate and appraise the available research evidence on implementation barriers and facilitators of interventions for children with visual impairments, their parents/guardians or educators. A systematic scoping search of peer-reviewed literature (including grey literature) was conducted from 15 June 2016 to 7 August 2016 and 2 May 2019 to 5 May 2019. Initial searches identified 6802 papers with 15 meeting the inclusion criteria. Three additional articles were identified through hand searching giving a final total of 18 included studies. The methodological quality score of the studies was variable with 61% scored in the average quality range. Sensory strategies, a family-centred approach, in-service training and routines-based activities were identified as implementation facilitators. Barriers were a lack of adaptive equipment and training for parents and professionals, complicating factors associated with the child's disability and an absence of specialists in interventions. Effective intervention strategies differ for this targeted population which requires individualised applications associated with teacher and parent/guardian training. For health or education professionals who work with children with visual impairments, the outcomes of this review suggest that a detailed assessment and identification of the individualised needs of children and their families, coupled with carefully designed and tested support practices to meet their individualised needs as well as promoting integrated working between health and care services, can optimise the positive implications for future practice. Along with this, future consideration should be given to the identification of the needs of children with visual impairments and additional disabilities in order to facilitate the adjustment of intervention strategies for this group.
WAS HE TRYING TO WHISTLE IT

1. 'A baffling doctrine, bafflingly presented' That there are things that cannot be put into words, but which make themselves manifest (TLP 6.522) is a leitmotif running through the whole of the Tractatus. It is heralded in the preface, in which the author summarizes the whole sense of the book in the sentence 'What can be said at all can be said clearly, and what we cannot talk about we must pass over in silence', and it is repeated by the famous concluding remark 'What we cannot speak about we must pass over in silence'. Wittgenstein's claim is, or at least seems to be, that by the very nature of language, or indeed of any system of representation whatsoever, there are things which cannot be stated or described, things of which one cannot speak, but which are in some sense shown by language. The numerous truths that seemingly cannot be stated, but which are nevertheless apparently asserted in the course of the Tractatus, can be sorted into the following groups: i. The harmony between thought, language and reality. There is (or seems to be) a harmony (or as Wittgenstein later put it, with deliberate Leibnizean allusion, a 'pre-established harmony' (BT 189)) between representation and what is represented. This harmony does not consist in the agreement of a true proposition with reality, since there are also false propositions. Rather it consists in the agreement of form between any proposition whatever and the reality it depicts either truly or falsely. This shared form, however, cannot itself be depicted. A picture can depict any reality whose form it has, but it cannot depict its pictorial form — it displays it (TLP 2.171). Propositions show the logical form of reality (TLP 4.12-4.121). ii. Semantics: One cannot say what the meaning of a symbol is. It is impossible to assert the identity of meaning of two expressions (TLP 6.2322). One cannot say what the sense of a proposition is; rather, a proposition shows its sense. A proposition shows how things stand if it is true, and it says that they do so stand (TLP 4.022). iii. Logical relations between propositions: One cannot say that one proposition follows from another, or that one proposition contradicts another. But that the propositions 'p e q', 'p' and 'q', combined with one another in the form '(pe q). (p):e:(q)', yield a tautology shows that 'q' follows from 'p' and 'p …
Daily and Intraday Herding within Different Types of Investors in Borsa Istanbul

ABSTRACT This paper aims to explore the daily and intraday herd behavior of various investor groups trading in an emerging equity market, Borsa Istanbul (BIST). We analyze a one-year tick-by-tick order and trade data of BIST 100 Index stocks and document differences in herding behavior of investor groups considering market capitalization, market conditions, and announcements as well as daily and intraday periodicities. We find that nonprofessional investors (brokerage houses and domestic funds) tend to herd on large (small) stocks; their herding behavior mostly exhibits a U shape (an inverse U shape) during the day. All types of investors tend to herd in down markets on a daily basis while this behavior disappears, even inverts intraday.
Optimal and Player-Replaceable Consensus with an Honest Majority

We construct a Byzantine Agreement protocol that tolerates t < n/2 corruptions, is very efficient in terms of the number of rounds and the number of bits of communication, and satisfies a strong notion of robustness called player replaceability (defined in [Mic16]). We provide an analysis of our protocol when executed on real-world networks such as the ones employed in the bitcoin protocol. ∗E-mail: silvio@csail.mit. edu †E-mail: vinodv@csail.mit. edu
