In this paper, we developed a virtual exposition as a model to visualize and demonstrate the dynamic and non-linear affordances of a learning rhizome. Virtual expositions are non-linear multimodal web installations that facilitate the creation of interconnections through which the research as practice and the practice as research are highlighted and communicated more effectively. Through a specific virtual exposition platform, we created a visual and performative representation of a rhizomatic learning course, allowing visitors to experience the complexity, multiplicity, unpredictability, and multivoicedness of such an approach in an isomorphic way. A complex learning rhizome is a performative confluence of human and non-human actors that engages people, resources, processes, and contextual parameters. As such, it is impossible to be represented in any representational format. The virtual exposition developed here attempts to offer a fair approximative model of rhizomatic learning which is far better than text-only linear representations. This paper offers a new view to rhizomatic learning as an applied practice that can enhance teaching and catalyze learning through complex synergies and dynamics. The originality of this paper lies in its attempt to bridge linear with non-linear academic research formats in order to offer a multimodal and performative model of rhizomatic learning. Theoretical and practical implications for learning and teaching are discussed.

The Creation

Since the early ’80s the adjective "intercultural" in language learning and teaching has seemed to acquire a remarkable importance, although its meaning is strongly debated. As a matter of fact, despite the existence of a vast literature on this topic, difficulties arise when applying it in the classroom. The aim of this work is to analyze the elements we consider to be the central pillars in this methodology, i.e. a renewed language-and culture relation, the Intercultural Communicative Competence, the intercultural speaker. These factors allow us to consider this as a new paradigm in language education; furthermore, they foster the creation of new potentialities and configure the classroom as a significant learning environment towards the discovery of Otherness.

AbstractDue to its provable security and remarkable device-independence, masking has been widely accepted as a noteworthy algorithmic-level countermeasure against side-channel attacks. However, relatively high cost of masking severely limits its applicability. Considering the high tackling complexity of non-linear operations, most masked AES implementations focus on the security and cost reduction of masked S-boxes. In this paper, we focus on linear operations, which seems to be underestimated, on the contrary. Specifically, we discover some security flaws and redundant processes in popular first-order masked AES linear operations, and pinpoint the underlying root causes. Then we propose a provably secure and highly efficient masking scheme for AES linear operations. In order to show its practical implications, we replace the linear operations of state-of-the-art first-order AES masking schemes with our proposal, while keeping their original non-linear operations unchanged. We implement four newly combined masking schemes on an Intel Core i7-4790 CPU, and the results show they are roughly 20% faster than those original ones. Then we select one masked implementation named RSMv2 due to its popularity, and investigate its security and efficiency on an AVR ATMega163 processor and four different FPGA devices. The results show that no exploitable first-order side-channel leakages are detected. Moreover, compared with original masked AES implementations, our combined approach is nearly 25% faster on the AVR processor, and at least 70% more efficient on four FPGA devices.

AbstractWhile the construction of knowledge hubs has gained recent traction, little is known on how networked actors perceive their collective culture. Authors looked at the topic through a single case study, the Design Factory Global Network, a network of 24 autonomous yet connected hubs for passion-based co- creation in an educational setting. Data was collected via questionnaires, asking 1) to describe their Design Factory in three distinct, words, 2) explicate these with exemplary stories, and 3) express future development wishes. 98 stories and future wishes were shared by representatives from 15 Design Factories. Excerpts reflecting cultural levels (attitudes, norms, manifestations) were identified and made sense of by looking at which level of stakeholder relationship (internal, host, network, wider environment) they targeted. 78 attitudes, 114 norms and 95 manifestations were mentioned, mostly targeting the internal community and the host levels. Authors draw some practical implications for each of the identified level or relationship, contributing to the knowledge of the creation and development of such innovation hubs. In addition, further research directions are proposed.

Purpose – The purpose of this paper is to present a system for customized binaural audio delivery based on the extraction of relevant features from a 2-D representation of the listener’s pinna. Design/methodology/approach – The most significant pinna contours are extracted by means of multi-flash imaging, and they provide values for the parameters of a structural head-related transfer function (HRTF) model. The HRTF model spatializes a given sound file according to the listener’s head orientation, tracked by sensor-equipped headphones, with respect to the virtual sound source. Findings – A preliminary localization test shows that the model is able to statically render the elevation of a virtual sound source better than non-individual HRTFs. Research limitations/implications – Results encourage a deeper analysis of the psychoacoustic impact that the individualized HRTF model has on perceived elevation of virtual sound sources. Practical implications – The model has low complexity and is suitable for implementation on mobile devices. The resulting hardware/software package will hopefully allow an easy and low-tech fruition of custom spatial audio to any user. Originality/value – The authors show that custom binaural audio can be successfully deployed without the need of cumbersome subjective measurements.

Purpose – The purpose of this paper is to profile how ample cash holdings can serve as a competitive advantage by first mitigating the risk of becoming a forced seller during times of distress, and then positioning a firm to take strategic advantage of forced selling and other forms of distress-generated opportunities. Design/methodology/approach – The author reviews the changing role of cash over time in corporate strategy, and how inadequate cash has caused or contributed to corporate failures. Findings – The findings of this paper, which are supported by historical and contemporary examples, are that ample cash reserves can be a powerful source of comparative advantage. Practical implications – This article supports earlier work published in Strategy & Leadership that shows how Graham-and-Dodd-based analysis is a viable avenue of academic research and a viable method with which to assess and formulate corporate strategic initiatives such as mergers and acquisitions, share buy-backs, risk management and, in this case, the strategic uses of cash. Originality/value – This paper offers leaders and financial executives a practical explanation of how ample cash holdings can serve as a competitive advantage.

Purpose The purpose of this paper is to contribute to the occupational status and entrepreneurship research in developing countries by proposing that there are implications for household consumption depending on the occupational status proportion of households. When the occupational proportion of the household changes, household consumption is affected. This effect also changes depending on what quantile level the household is in terms of household consumption. Design/methodology/approach The paper makes use of OLS and quantile regressions to examine 6,919 households comprising 40,294 individuals from the 2009 Nigerian Living standards measurement survey. Findings The paper finds that there are implications for household consumption based on the proportion of individuals in each occupational category. The contributions of each employment proportion changes at different quantiles with self-employed individuals increasing household consumption at the lower quantiles but reducing household consumption at the upper quantiles. Crucially, having a higher proportion of unemployed individuals in the household is oftentimes better than having a higher proportion of own account self-employed individuals. Research limitations/implications This paper offers new insights into how occupation proportion influences household consumption in developing countries. As a result, the household could seek to organise its members in such a way as to maximise combined household consumption, as diverse occupational statuses contribute differently to the household consumption at different quantile levels. The nature of the data used in this study however does not allow for causality tests. Practical implications The proportion of employment statuses in the household has implications for household consumption and so the mix of employment in the household is important. The self-employed could also be involved in activities to enhance household consumption that are not captured by labour income. However, self-employment does not seem to always have a positive effect on household consumption and sometimes unemployment might be better. Originality/value The paper provides a new way to view the household as an organising entity in terms of how it can allocate employment proportions to maximise household consumption.

Purpose – The purpose of this paper is to explore the difference between Open Access and accessibility, to argue that accessibility is the most crucial feature, and to suggest some ways in which Open Access militates against accessibility. Design/methodology/approach – Analysis of best practice by journals and monograph publishers is used to highlight the degree to which accessibility is enhanced by input from readers and editors. The expense of this, both real and hidden, is shown to be compatible only with difficulty with publishing methods where keeping costs low is essential, and Open Access alternatives that make available manuscripts “as submitted” are shown to make available less accessible scholarship. Findings – Scholarship is markedly improved by referees and editors; the emphasis needs to be put on making available the most accessible scholarship, not on making more scholarship available. Practical implications – Journals and publishers should concentrate on, and research councils and similar bodies insist upon, ensuring high quality critical review and editing, not cost-free access. Originality/value – The debate on Open Access has put its emphasis in the wrong place. Rather than easier access to more scholarship, increased resource devoted to pre-publication review, revision and editing is the most important development to ensure the greatest advances in research and scholarship.
