The index of some mixed order Dirac type operators and generalised Dirichlet–Neumann tensor fields

AbstractWe revisit a construction principle of Fredholm operators using Hilbert complexes of densely defined, closed linear operators and apply this to particular choices of differential operators. The resulting index is then computed using an explicit description of the cohomology groups of generalised (‘harmonic’) Dirichlet and Neumann tensor fields. The main results of this contribution are the computation of the indices of Dirac type operators associated to the elasticity complex and the newly found biharmonic complex, relevant for the biharmonic equation, elasticity, and for the theory of general relativity. The differential operators are of mixed order and cannot be seen as leading order type with relatively compact perturbation. As a by-product we present a comprehensive description of the underlying generalised Dirichlet–Neumann vector and tensor fields defining the respective cohomology groups, including an explicit construction of bases in terms of topological invariants, which are of both analytical and numerical interest. Though being defined by certain projection mechanisms, we shall present a way of computing these basis functions by solving certain PDEs given in variational form. For all of this we rephrase core arguments in the work of Rainer Picard [42] applied to the de Rham complex and use them as a blueprint for the more involved cases presented here. In passing, we also provide new vector-analytical estimates of generalised Poincaré–Friedrichs type useful for elasticity or the theory of general relativity.

Celebrating the 60th anniversary of the Asia Pacific Journal of Human Resources: what has been achieved and what more can be done

The Asia Pacific Journal of Human Resources (APJHR) celebrates its 60th anniversary in 2022. In this 60th anniversary issue, we provide a brief overview of the APJHR and its recent developments. We outline a few thematic areas, with indicative research questions that would facilitate researchers to extend the field of HRM research with policy relevance and societal impact in the Asia Pacific, drawing on several megatrends as the context. These include demographic changes, climate change and energy transition, digital technology and the growing interest in HR analytics, and the global pandemic. We then present a collection of review articles included in this anniversary issue that provide a critical appraisal, from a historical lens, of selected research topics including those published in the APJHR; we reflect on how they have evolved and what further research efforts can be exerted to advance the field.

The pregnancy experiences of amputee women: a qualitative exploration of online posts

ABSTRACT Background This paper seeks to explore the pregnancy experiences of amputee women. Relatively little is known about pregnancy for amputees, but the wider literature on disability and pregnancy shows that the disabled pregnant body is often viewed as ‘high risk’. The majority of amputations (90%) involve lower limb amputations; whilst our analytical interest was not limited to lower limb amputations, the sources we explored reflected the prevalence of lower limb amputees. Methods Using online blogs and first-person accounts from 6 different sources (3 authors of blogs, 2 authors of websites and 1 author of an information page on a general amputation website), we thematically analyse amputee women’s own narratives around their experiences of pregnancy Findings Four key themes were identified, which we describe as: The lack of information for the pregnant amputee; Managing risks; The embodied experience of suffering; and ‘It’s all worth it in the end’. Women amputees faced trade-offs between risks to self and the unborn child and reported physical discomforts due to pregnancy-related bodily changes impacting their prosthesis or residual limb. The challenges of pregnancy as an amputee were, however, all seen to be outweighed by the safe arrival of a healthy baby. Conclusions The lack of information on pregnancy for amputees may affect women’s resilience to the adaptation challenges they face. Research should further explore the experiences of amputee mothers to ensure adequate information is available to them and their caring professionals, and that the needs of women with more challenging experiences are also addressed.

Logic and Voice

In this paper, I aim to reconstruct and discuss Stanley Cavell’s interpretation and critique of analytic philosophy. Cavell objects to the tradition of analytic philosophy that, in its eagerness to provide abstract, theoretical reconstructions, it has failed to understand the importance of “the human voice” for philosophy. First, I outline Cavell’s retelling of the history of analytic philosophy from Frege and Russell to ordinary language philosophy. Second, I turn to Cavell’s reading of Kierkegaard and Wittgenstein in order to show what the suppression of the human voice is supposed to mean and entail. Central to Cavell’s account is a particular view of language according to which no structure can explain our capacity for sense-making. Third, I exemplify Cavell’s approach by analyzing his debate with Kripke. Kripke sees the absence of “rails” determining meaning as a skeptical problem and calls for a communal solution. Cavell, by contrast, accepts the absence of rails while highlighting the need for individual responsiveness. In the conclusion I contrast the analytic interest in theory, structure, and abstraction with what I see as Cavell’s humanism. While respectful of key aspects of the analytic tradition such as its commitment to rigor and transparency, Cavell wished to bring the human subject back into philosophy.

Между «своим» и «чужим»: языковые и художественные реалии, проблемы, перспективы литератур народов Крайнего Севера и Дальнего Востока

The article discusses linguistic and artistic realities, problems and perspectives of the literatures of the indigenous peoples of the North and the Far East. The author fixes the widespread writing of works in Russian, comprehends the reasons for the linguistic transition, raises the question of the theoretical and substantive expansion of the concept of “national literature”, emphasizes the importance of the individual author's ethnocultural component. The author considers as a landmark projection of the development of “minority” national literatures the method of including elements of the “native” language in a Russian-language poem, an appeal to the topic “native language”, the experience of accidentally recognizing one's own in the sounds of a genetically non-native language. Special attention is paid to the problem of literary translation into Russian, some scenarios of distortion of texts in translations and reduction precedents of important mythological contexts are presented. The conclusions obtained during the analysis of a large corpus of poetic texts from the Nenets, Dolgan, Even, Chukchi, Koryak, Nanai literatures can be of significant analytical interest in a comparative aspect.

Interaction in asynchronous discussion boards: a campus-wide analysis to better understand regular and substantive interaction.

Discussion boards can provide a glimpse into the regular and substantive interaction required in online courses. Advances in technology and an increased interest in learning analytics now provides researchers with billions of data points about instructor and student interaction within a learning management system (LMS). This study used LMS data to explore the frequency of interaction between instructors and students in discussion boards in online courses at one institution. Overall, 415 courses were analyzed spanning two semesters. Results from the study found that the average number of posts by an instructor was 32.9. The average instructor interaction was 1.49 instructor posts per student. 23% of courses had no instructor posts. Student posts averaged 470 per course and the average posts per student was 19.9. Based on the discussion board activity, the most discussion interaction occurred during the first two weeks of the semester. Results also suggested that there is no relationship between student satisfaction and the number of total posts in a course. The paper concludes with implications for research and practice.

The challenge of learning analytics implementation: lessons learned


 
 
 Despite broad interest in learning analytics across the Australian Higher Education sector, there remains few examples of institution-wide implementations. Learning analytics implementation is currently under-theorised with little knowledge of the complexities that mediate the systemic uptake required for an institution-wide implementation. It has been established that approaches to learning analytics that are exclusively top-down or bottom-up, are insufficient for successful implementation across an enterprise. Drawing upon an award-winning and institution-wide learning analytics intervention that has been used across almost 5,000 unit offerings, this paper formulates an initial set of theory informed design principles that can help learning analytics practitioners mediate the complexities of institution-wide implementation.

Performing social media analytics with Brandwatch for Classrooms: a platform review

As consumer’s consumption of digital media and usage of social media platforms continues to grow, businesses have been searching for new ways to track, analyze, and measure this online consumer behavior to support a diverse set of business functions such as marketing, customer support, and customer experience management. Given the heightened interest in social media analytics in the business community, educational institutions have also been interested in identifying new ways to introduce emerging social media analytics concepts and practices to their students. One category of social technologies that is specifically used to perform this type of analysis is social listening platforms. Brandwatch (recently acquired by Cision Ltd.) has created one of the leading social listening platforms. They also offer a version of this platform for educators named Brandwatch for Classrooms. This article provides an overview of the key features and capabilities of the Brandwatch for Classrooms platform, as well as numerous suggestions for incorporating the platform in marketing analytics undergraduate and graduate courses. The goal is to provide educators with practical information about social media analytics and guidance on successfully integrating social listening platforms in their course design.

Identification of high-affinity phage-displayed VH fragments by use of a quartz crystal microbalance with dissipation monitoring

• Selection of phage-displayed antibody fragments selective to PHA legume lectin. • QCM-D as an effective tool for the evaluation of biomolecular interactions. • Multiparameter analysis identifies clone clusters with similar binding properties. • Improvement of the design of label free bioanalytical assays. Phage display has become a powerful tool for antibody discovery in a wide variety of fields. This technology allows specific binders for a given antigen to be selected from combinatorial libraries. A key step in the process is characterizing and evaluating antibody clones thus selected to reliably identify the best antigen binders. Novel characterization methods can provide essential insight into the binding mechanism and supplement the information obtained with conventional techniques. In this work, we used a quartz crystal microbalance with dissipation monitoring (QCM-D) to determine the kinetic and thermodynamic binding parameters for phage-displayed V H antibody fragments. Phytohemagglutinin (PHA), a legume lectin of analytical interest, was used as a complex model antigen to select specific V H fragments from a phage-displayed library. Eight V H fragments with a unique amino acid sequence were identified as PHA binders by using the well-established enzyme-linked immunosorbent assay (ELISA). QCM-D measurements, structural analysis and principal component analysis (PCA) were used to evaluate the antibody fragments and identify clone clusters with similar binding characteristics and molecular interaction mechanisms. This unprecedented study has enabled the identification of high-affinity phage-displayed V H antibody fragments for PHA, which could be useful for PHA analysis (apparent association constant ranged from 10 8 to 10 10 M −1 ). In fact, the proposed methodology provides a useful tool for evaluating and characterizing antibody fragments with capabilities beyond those of conventional techniques.

Introduction - Multi-stakeholder forums and the promise of more equitable and sustainable land and resource use: perspectives from Brazil, Ethiopia, Indonesia, and Peru

Multi-stakeholder forums (MSFs) have become a popular mechanism in global development and conservation circles, given the urgency to find transformative approaches to address climate change and unsustainable development. In this current context, it is important to take stock of MSFs, an example of a participatory mechanism that is emerging as a new 'solution'. The papers in this Special Issue of the International Forestry Review derive from a multi-country comparative research project carried out by the Center for International Forestry Research (CIFOR) that aimed to understand how best to support MSFs organised for more sustainable land and resource use. The seven papers assess the potential of MSFs for more equitable decision-making in regard to land and resource use sustainability, and engage with scholarly debates over these forms of participation. The papers approach MSFs from different theoretical perspectives and analytical interests, yet all engage with issues that stem from the power inequalities that are inherent to these forums. The papers provide more evidence – and a warning – that to get closer to transformational change, we need MSFs that do more than simply bring people to the table.

“Metaphysics about Metaphysics.” Kant on Theoretical, Practical and Practico-Theoretical Metaphysics

The essay investigates the relation between metaphysics and practical philosophy in Kant by reconstructing Kant‘s systematic typology of metaphysics as developed in his critical writings. Section 1 deals with Kant’s rigorous reduction of philosophy to metaphysics. The focus here is on the epistemological turn effectuated by Kant with regard to metaphysics (theoretical metaphysics). Section 2 is concerned with Kant’s reconceptualization of (pure) practical philosophy as a metaphysics sui generis. At the center stands here Kant’s supplementation of the metaphysics of nature through a metaphysics of morals based on moral freedom (practical metaphysics). Section 3 addresses the merging of theoretical and practical metaphysics in Kant. The focus here lies on Kant’s introduction of a novel, practically validated form of (quasi-)theoretical metaphysics (practico-theoretical metaphysics). Throughout the essay combines an analytic interest in the forms and functions of metaphysics in Kant with a systematic interest in the practical and practico-theoretical transformation of previously theoretical metaphysics in Kant, which morphs from a doctrine of the objects of nature through a doctrine of the laws of freedom to a doctrine of wisdom regarding the supersensible.

Dirty work och professionalisering

The concept of teaching, previously primarily reserved for formal school activities, has today a prominent position in the educational assignment for preschool and school-age educare. The study examines how this concept is managed by preschool- and school-age educare teachers and highlights how talking about teaching seems both troublesome and useful. Analytical interest is directed at how discursive boarder work is staged in order to preserve existing professional territories but also to gain new legitimacy. The use of the concept of teaching risks undermining the specificity of the professional roles and is described as an undesirable task – dirty work. At the same time, the concept serves as a usable resource to enhance the credibility of preschool and school-age educare teachers. Talking of teaching seems appropriate to use outwards, to show that the changes in the professional assignment are complied with. However, it seems inappropriate to apply the concept of teaching in the actual work with children. Therefore, the concept –imposed by educational policy authorities – does not change the work of preschool and school-age educare teachers but, nevertheless. contributes to its professionalization.

Is data science a science? The essence of phenomenon and the role of theory in the emerging field

PurposeData science lacks a distinctive identity and a theory-informed approach, both for its own sake and to properly be applied conjointly to the social sciences. This paper’s purposes are twofold: to provide (1) data science an illustration of theory adoption, able to address explanation and support prediction/prescription capacities and (2) a rationale for identification of the key phenomena and properties of data science so that the data speak through a contextual understanding of reality, broader than has been usual.Design/methodology/approachA literature review and a derived conceptual research model for a push–pull approach (adapted for a data science study in the management field) are presented. A real location–allocation problem is solved through a specific algorithm and explained in the light of the adapted push–pull theory, serving as an instance for a data science theory-informed application in the management field.FindingsThis study advances knowledge on the definition of data science key phenomena as not just pure “data”, but interrelated data and datasets properties, as well as on the specific adaptation of the push-pull theory through its definition, dimensionality and interaction model, also illustrating how to apply the theory in a data science theory-informed research. The proposed model contributes to the theoretical strengthening of data science, still an incipient area, and the solution of the location-allocation problem suggests the applicability of the proposed approach to broad data science problems, alleviating the criticism on the lack of explanation and the focus on pattern recognition in data science practice and research.Research limitations/implicationsThe proposed algorithm requires the previous definition of a perimeter of interest. This aspect should be characterised as an antecedent to the model, which is a strong assumption. As for prescription, in this specific case, one has to take complementary actions, since theory, model and algorithm are not detached from in loco visits, market research or interviews with potential stakeholders.Practical implicationsThis study offers a conceptual model for practical location–allocation problem analyses, based on the push–pull theoretical components. So, it suggests a proper definition for each component (the object, the perspective, the forces, its degrees and the nature of the movement). The proposed model has also an algorithm for computational implementation, which visually describes and explains components interaction, allowing further simulation (estimated forces degrees) for prediction.Originality/valueFirst, this study identifies an overlap of push–pull theoretical approaches, which suggests theory adoption eventually as mere common sense, weakening further theoretical development. Second, this study elaborates a definition for the push–pull theory, a dimensionality and a relationship between its components. Third, a typical location–allocation problem is analysed in the light of the refactored theory, showing its adequacy for that class of problems. And fourth, this study suggests that the essence of a data science should be the study of contextual relationships among data, and that the context should be provided by the spatial, temporal, political, economic and social analytical interests.

Российское просвещение как источник формирования национальной философии

The study is devoted to the philosophical understanding of the problem of the cultural origins of Russian philosophy. In the author’s opinion, the source of diversity of modern approaches to the phenomenon of Russian Philosophy is, first of all, the absence of a unified methodological approach. The diversity of research on the phenomenon of the Russian philosophy origins is also a consequence of research susceptibility to certain methodological influences. The paper aims to identify a number of philosophical, historical, literary approaches to the problem of the genesis of the eighteenth century Russian Enlightenment. It is necessary to clarify the mechanisms and procedures for the reception of Western European ideas and concepts by Russian Enlightenment during the eighteenth century. On the basis of adaptation of natural law terms, the author considers certain trends in the theory of reconstruction of the Enlightenment phenomenon in Russia. He reveals a number of significant features of the process of reconstruction of the Enlightenment ideology formation on Russian soil, including the idea that European concepts and theories are assimilated by the domestic semiosphere in the form in which they existed in the culture of the West. The author highlights the idea, that researchers were convinced that Russia of the XVIII century already had a national philosophy. The paper also draws attention to the lack of analytical interest in the problems of transformation of the language of expression of political phenomena. In the same row, there is also the idea that the process of reception of the enlightenment heritage of the West had a revolutionary, not an evolutionary, specificity, and was devoid of cultural prerequisites. Basing on the material of historical and historical-philosophical studies, the author considers the possibilities of constructing a methodologically integral reconstruction, chronologically covering the entire period of the XVIII century. The research methodology is based on the approach that includes an analytical description of the problems of the thematic fields of discourse, concepts and theories of the Enlightenment on the Russian soil. The result of the analysis is the systematization of contradictions in the process of analyzing the phenomena of the Russian Enlightenment in the XVIII century.

Welcome Back, We’ve Missed You! Humanized Business Communication in Shop Window Messages during Early 2020-Lockdown

This paper focuses on the way in which small and medium-sized businesses in Flanders adapted communication with their customers during the economic lockdown in March–May 2020. It documents, more specifically, how shops tried to maintain, re-establish, or even re-invent communication with their customers during this two-month period. Based on pictures of shop windows in a Flemish city, we analyze the (semi-)commercial messages that appeared in this setting during this period. This analysis adopts an interdisciplinary perspective, in which a cognitive linguistic approach is integrated with analyses and practical advices by marketing agencies. Despite their orientation towards distinct, theoretical and practical goals, both approaches share an analytical interest in mapping participants and their mutual relationship as part of a communicative interaction. In the period of economic lockdown, marketers urged shop owners to ‘humanize’ their business strategy by downplaying content-related issues in favor of maximal social outreach towards customers. Considering this advice, it was hypothesized that under these circumstances participants in commercial transactions would be construed much more prominently, presenting themselves and each other as unprecedented empathetic business personas. Much of our data comply with this expectation, thus providing empirical evidence of a subjectified communicative ground, in which both buyer and seller personas figure with augmented prominence as parts of the object of conceptualization. Messages include, among other things, expressions of empathy, solidarity, combativity, but also creativity and humor thus incorporating a new type of humanized business communication. With respect to the analysis of marketing strategies, the collected data at the same time instantiate and legitimize marketers’ communication advice about humanizing one’s business exchange.

Staying on target: A systematic literature review on learner‐facing learning analytics dashboards

AbstractThe advances in technology to capture and process unprecedented amounts of educational data has boosted the interest in Learning Analytics Dashboard (LAD) applications as a way to provide meaningful visual information to administrators, parents, teachers and learners. Despite the frequent argument that LADs are useful to support target users and their goals to monitor and act upon the information provided, little is known about LADs’ theoretical underpinnings and the alignment (or lack thereof) between LADs intended outcomes and the measures used to evaluate their implementation. However, this knowledge is necessary to illuminate more efficient approaches in the development and implementation of LAD tools. Guided by the self‐regulated learning perspective and using the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) framework, this systematic literature review addressed this gap by examining whether and how learner‐facing LAD’s target outcomes align with the domain measures used to evaluate their implementations. Out of the 1297 papers retrieved from 15 databases, 28 were included in the final quantitative and qualitative analysis. Results suggested an intriguing lack of alignment between LADs’ intended outcomes (mostly cognitive domain) and their evaluation (mostly affective measures). Based on these results and on the premise that LADs are designed to support learners, a critical recommendation from this study is that LADs’ target outcomes should guide the selection of measures used to evaluate the efficacy of these tools. This alignment is critical to enable the construction of more robust guidelines to inform future endeavours in the field. Practitioner notesWhat is already known about this topic There has been an increased interest and investment in learning analytics dashboards to support learners as end‐users. Learner‐facing learning analytics dashboards are designed with different purposes, functionalities and types of data in an attempt to influence learners’ behaviour, achievement and skills. What this paper adds This paper reports trends and opportunities regarding the design of learner‐facing learning analytics dashboards, contexts of implementation, as well as types and features of learner‐facing learning analytics dashboard studies. The paper discusses how affect and motivation have been largely overlooked as target outcomes in learner‐facing learning analytics dashboards. Implications for practice and/or policy Based on the evidence gathered through the review, this paper makes recommendations for theory (eg, inclusion of motivation as an important target outcome). The paper makes recommendations related to the design, implementation and evaluation of learning analytics dashboards. The paper also highlights the need for further integration between learner‐facing learning analytics dashboards and open learner models.

Strategic value realization framework from learning analytics: a practical approach

PurposeIn spite of the popularity of learning analytics (LA) in higher education institutions (HEIs), the success rate and value gained through LA projects is still little and unclear. The existing research on LA focusses more on tactical capabilities rather than its effect on organizational value. The key questions are what are the expected benefits for the institution? And how the investment in LA can bring tangible value? In this research, the authors proposed a value realization framework from LA extending the existing framework of information technology value.Design/methodology/approachThe study includes a detailed literature review focusing on the importance, existing frameworks and LA adoption challenges. Based on the identified research gap, a new framework is designed. The framework depicts the several constructs and their relationships focusing on strategic value realization. Furthermore, this study includes three case studies to validate the framework.FindingsThe framework suggests that leveraging LA for strategic value demands adequate investment not only in data infrastructure and analytics but also in staff skill training and development and strategic planning. Universities are required to measure the strategic role of LA and spend wisely in quality data, analytical tools, skilled staff who are aware of the latest technologies and data-driven opportunities for continuous improvement in learning.Originality/valueThe framework permits education leaders to design better strategies for attaining excellence in learning and teaching, and furnish learners with new data to settle on the most ideal decisions about learning. The authors believe that the appropriation of this framework and consistent efficient interest in learning analytics by the higher education area will prompt better results for learners, colleges and more extensive society. The research also proposes two approaches and eleven research agendas for future research based on the framework. The first is based on the constructs and their relationships in LA value creation, whereas the later one focusing on identifying problems associate with it.

Investigating student engagement with intentional content: An exploratory study of instructional videos

In recent years, flipped classrooms have become increasingly popular in higher education environments. In tandem, there is an increasing interest in engagement analytics and educational data mining to identify how students directly engage with content and resources. The Flipped Learning Network (FLN) defines flipped learning as a pedagogical approach in which direct instruction moves from the group learning space to the individual learning space. The resulting group space is transformed into a dynamic, interactive learning environment where instructors guide students as they apply concepts and engage creatively with subject matter. To engage in flipped learning effectively, instructors incorporate four pillars into their educational practice (F-L-I-P): Flexible Environment, Learning Culture, Intentional Content and Professional Educator.This study focuses primarily on one pillar of F-L-I-P i.e., Intentional Content, provided to maximise classroom time, to better utilise teaching and learning methods for a more student-centred, active learning experience. This exploratory study uses log-file data generated by the Learning Management System (LMS) to identify patterns, usage, and engagement of 468 undergraduate students. Firstly, the study investigates what intentional content students effectively engage with, for learning. Secondly, it investigates usage frequency and specific intervals, with a view to identifying critical times in the semester where intentional content is perceived as essential by students. Thirdly, the study explores how intentional content supplements other elements of the FLIP environment.Preliminary findings indicate a discernible pattern of usage, and usage frequency of intentional content amongst students. Engagement is ad hoc; and in the main the behaviour is fragmented, inconsistent, and disjointed-overall students are not engaging effectively and consistently. Additionally, the distribution of intentional content engagement is skewed towards the start and end of semester, emphasising these intervals as critical points. Of note, more consistent behaviour is adopted at the beginning of the module, however students become less engaged with all content as the term progresses. Conversely, a change in student behaviour is observed as the term comes to a close, whereby more positive patterns emerge -perhaps attributable to pending examinations.

Smart Cities and Big Data Analytics: A Data-Driven Decision-Making Use Case

Interest in smart cities (SCs) and big data analytics (BDA) has increased in recent years, revealing the bond between the two fields. An SC is characterized as a complex system of systems involving various stakeholders, from planners to citizens. Within the context of SCs, BDA offers potential as a data-driven decision-making enabler. Although there are abundant articles in the literature addressing BDA as a decision-making enabler in SCs, mainstream research addressing BDA and SCs focuses on either the technical aspects or smartening specific SC domains. A small fraction of these articles addresses the proposition of developing domain-independent BDA frameworks. This paper aims to answer the following research question: how can BDA be used as a data-driven decision-making enabler in SCs? Answering this requires us to also address the traits of domain-independent BDA frameworks in the SC context and the practical considerations in implementing a BDA framework for SCs’ decision-making. This paper’s main contribution is providing influential design considerations for BDA frameworks based on empirical foundations. These foundations are concluded through a use case of applying a BDA framework in an SC’s healthcare setting. The results reveal the ability of the BDA framework to support data-driven decision making in an SC.
