Re-mediating classroom activity with a non-linear, multi-display presentation tool

This paper uses an Activity Theory framework to evaluate the use of a novel, multi-screen, non-linear presentation tool. The Thunder tool allows presenters to manipulate and annotate multiple digital slides and to concurrently display a selection of juxtaposed resources across a wall-sized projection area. Conventional, single screen presentation systems have been frequently criticised in the literature. Yet very little work has investigated the use of multi-screen alternatives, particularly within authentic activity systems. We placed the Thunder tool into an established activity system of student presentations in University-level Architecture education and examined how that system was re-mediated by participants' use of the tool. Our instruments included in-room and video-based observations, questionnaire responses and transcribed interviews. We analyse how using Thunder in this setting re-mediated conventional activity structures in terms of interactivity, efficiency, cost, failure and serendipity. Drawing actions became prominently used to support design arguments, resulting in the ‘easel’ screen becoming a site for struggle between students and tutors. Slide manipulation was not well managed by students and yet the disorganised wall projection area nonetheless supported a directness of communication between participants that was novel for the activity. Students' historical learning costs, in terms of time and money, were removed, serving as the basis for the more fluid, contingent interactions, while participants' perception of tool failure was heavily influenced by prior expectations and historical activity forms. Novel forms of serendipitous discovery were enabled by the juxtaposition and annotation of materials, but such discovery was possible for both student-presenters and their audience and could be used to challenge presenters' narrative. We conclude by discussing how the re-mediation we document is pertinent to the contradictions in the activity system and suggest that, for the particular activity system we studied, a new leading form of the activity system would need to emerge if tools such as Thunder are to better mediate student presentation activity. ► Evaluates learners' use of a multi-screen, non-linear presentation tool. ► The evaluation makes explicit the tool's adoption into an authentic activity system. ► Drawing actions supported direct communication around presenters' arguments. ► Multi-screen projection area was disorganised but supported serendipitous discovery. ► Students and tutors harnessed drawing and multi-display discordantly.
Noise transfer function design for delta-sigma modulators using the Gegenbauer polynomial

Abstract An efficient noise transfer function (NTF) is central to the design of a delta-sigma modulator (DSM). A popular method for designing an NTF is based on the placement of its zeros optimally in the frequency band of interest such that the in-band energy is minimized. The poles of the NTF, however, are those of a maximally-flat all-pole filter. The limitation of this method is that when the oversample ratio (OSR) of the DSM is low, the 3-dB cutoff frequency of the denominator polynomial of the NTF may approach the edge of the passband of the NTF. This causes the zeros to no longer be optimal. In this paper, we present a method of designing an NTF based on the Gegenbauer polynomial which does not have this limitation. We show that the signal-to-quantization noise ratio (SQNR) of the NTFs designed with our method is significantly better than that of the NTFs designed using the well-known method.
Expected Difference, Equity Nature and the Corporate Control Agreement Transfer Failed—the Evidence from China

This paper has researched the issue of corporate control transfer failed in china capital market, which is completely different from existing studies in corporate control transfer field. The conclusion has shown that corporate control transfer very likely fails when there is a great difference between two sides of deals. And the equity nature is another affection factor. The corporate control transfer is not likely to fail when the equity nature is state-owned. The conclusion implies that we should make more improvement for institutions of corporate control transfer, because of the lack of market voluntary trade rule in china capital market.
Oscar: the first device for managing a warehouse of articles able to visually recognise any label without the need of a barcode.

VH Technology srl invented and designed a device able to automatically identify products by recognising their label when the product passes in front of the device camera. It recognises the product by looking at the label as a human would do. Allowing automatic warehouse management without the need of a barcode, RFID or other types of specially designed labels.
This device uses sophisticated machine vision technology developed by VH Technology and is the first worldwide. A patent application has been filled. PCT application: PCT/EP2016/062247.
The idea was initially born to answer a specific need: Cellar management. Today it is mostly performed in a manual way since wine bottles do not necessarily have a barcode (or may have same barcode for different vintages) and applying RFID tag on each bottle is expensive and time consuming. Manual inventory is more prone to errors, therefore frequent cellar inventory is necessary which is tedious and time consuming. Moreover manual inventory is very ineffective in preventing frequent losses of valuable bottles.
Since our solution is well suited for cellar management VH Technology decided that the first device using this technology to be developed and launched on the market would target cellar management. At the same time VH Technology intends to apply this technology in multiple other fields.
VH Technology developed 4 prototypes which have been extensively tested and have demonstrated technical feasibility, ease of use as well as significant efficiency increase compared to cellar management.
Initial target: Restaurants, hotels, wine bars, wine shops, private wine collectors. To be extended to other labelled products.
Market: Worldwide.
Objectives phase 1: Detailed marked analysis to improve Oscar. Examine other applications/markets for our device.
Objectives phase 2: From Oscar prototype to final product development (design to manufacture).

Language switching and script mixing: multilingual landscapes of medieval scandinavia

The present project aims to investigate the encounter between the Latin and the native vernacular written culture in medieval Scandinavia, through phenomena of language and script switching in epigraphic sources. The spread of Latin is a pivotal point in the development of all European literate societies. Scandinavia represents a unique case study where Latin and the Roman script encountered and mixed itself with an 800 year old native tradition based on the local vernacular and the runic script. From being monolingual and monoscriptal, Scandinavia became multilingual and multiscriptal.

Through an interdisciplinary framework to be developed in synergy with leading scholars at the University of Oslo, epigraphic methods completed by multimodal and sociolinguistic analyses within a linguistic landscape perspective will serve to determine: 1) the medieval writers’ multilingual and multiscriptal proficiency; 2) the status relationship between the Latin and runic written tradition; and 3) the ideological presuppositions and purposes of the use of different languages and scripts.

For the first time, these phenomena will be studied systematically and through an unexplored combination of historical material and modern sociolinguistic methods. This will not only yield new insights in the multilingual literacy of medieval Scandinavia and on its underlying cultural and ideological aspects, but also in its significance in a European context. By embedding the Scandinavian case in the process of cultural and political formation of Europe, this project will also contribute to understand the common cultural heritage in modern European societies.
Advanced techniques for SEismic RISK reduction in Mediterranean Archipelago Regions

In the last years there has been a growing concern in the scientific community working on seismic hazard regarding the need for widening the scope of hazard studies, in order to achieve a better understanding not only of the physical direct damage due to earthquakes, but also of the comprehensive response of a geosystem at different scales. Another important issue should be to improve the communication between the scientific community and the end-users: i.e., public administrations and decision makers. Decision makers in earthquake-prone cities and prefectures need concrete figures of the possible impact of seismic events. The project SE-RISK will develop a general and modular methodology for creating earthquake-hazard scenarios that concentrates on the distinctive features of Mediterranean Archipelago towns and sub-regions, including examples from current and/or historical buildings. It will be based on seismic hazard assessment, a systematic study of the elements at hazard and a preliminary analysis of their vulnerability of some particular elements. The resulting seismic hazard will give concrete figures of possible direct and indirect damage of earthquakes. With the participation of urban council representatives, the methodology will then be applied as an example to selected part of cities from the Mediterranean Archipelago for its adaptation and validation. Where the methodology for seismic hazard assessment will be implemented a GIS based prototype will be developed. An important feature of this prototype will be the guidance of decision makers in making hazard assessment at local and sub-regional geographical scales, where different goals are pursued at each scale, and different information is also needed. A Mediterranean Archipelago network for the study of seismic hazard will be created during a final conference.
Absent presences: an ethnographic study of the uncounted lives of people affected by leprosy in latin america

This research project focuses on the absent presences of people affected by leprosy in the World Health Organization’s (WHO) making of a leprosy-free world. In 2000, WHO announced the achievement of the global elimination of leprosy as a public health problem (defined by a prevalence rate of less than one case per 10,000 persons). Since the introduction of multidrug therapy (MDT) in the 1980s, the number of cases registered globally has decreased from over 5 million to about 200,000 cases. However, many scholars have suggested that such an extraordinary decrease is not due to a drop in transmission rates, but rather to an increase in misdiagnosed cases. They argue that the announcement of the global elimination of leprosy has caused the closing down of active surveillance campaigns as well as a progressive loss of expertise in diagnosis and treatment of leprosy.  According to some estimates, between the years 2000 and 2020 as many as 4 million cases will be overlooked worldwide. This process has given rise to new challenges such as the increase of foreign-born cases in countries in the Global North. Drawing on literature from Science and Technology Studies (STS), medical anthropology and critical studies of global health, I propose to conduct a multi-sited ethnography focused on the uncounted lives of people affected by leprosy across borders in Latin America, examining WHO’s ongoing leprosy-free world project in specific settings. I argue that, in order to understand a possible drop in new cases and/or increase in under- and misdiagnosis, it is necessary to examine both local heterogenous elements and modifications in WHO’s global leprosy program. In particular, I will explore the modes of production of statistical data, central to evidence-making processes in the global epidemiological reality of leprosy.
Socialist high modernity and global stagnation: a shared history of Brazil and the Soviet Union during the Cold War

Abstract This article questions a prevailing bipolarity of traditional Cold War history by examining commonalities and interactions between the Soviet Union and Brazil in the 1950s and 1960s. After outlining the common characteristics of both states around 1960, it analyses the cultural diplomacy of the post-Stalinist Soviet Union towards Brazil. Transforming its hitherto prevailing image as the cradle of world revolution and communist class struggle, the USSR now represented itself as a role model for the quick industrialization of the economy and education of the masses. Many Brazilian intellectuals and political reformers from President Kubitschek to President Goulart shared with the Soviets an interest in what is here called ‘socialist high modernity’. Contacts with the Soviet Union were connected to the putsch and the end of Brazilian democracy in 1964. However, the new military leaders also had their own interests in, and surprisingly good relations with, the stagnating Soviet Union. This was again based on a set of commonalities in the historical development of the two ostensibly idiosyncratic and distant states on either side of the Iron Curtain. Eschewing teleological interpretations of the period and exploring the ideational basis of actors in the conflict, this article – based on new documents from Moscow archives and recently declassified sources from the Brazilian Foreign Ministry – aims to link Cold War historiography to the debates on global history, which have lately neglected both Latin America and eastern Europe.
Effect of open air drying, LPG based drier and pretreatments on the quality of Indian gooseberry (aonla)

The aonla fruits (whole fruit, pricking, splits, segments) were subjected to pretreatments like blanching, osmotic dehydration with salt (2%) and sugar (40%) in different experiments before drying to obtain a product with better keeping quality. An LPG based drier (CRIDA drier) with capacity to dry 50 kg of fresh Indian gooseberry (aonla) was used. Nutritional quality and rehydration characteristics of CRIDA drier dried products were higher and free from contamination. Drying time was shortest for blanched and osmotically dehydrated segments dried in CRIDA drier and the product had better vitamin C retention, rehydration characteristics and sensory acceptability compared to sun or cabinet drier dried product. The additional expenditure spent on gas in CRIDA drier is compensated by reduced labour cost and higher price for the better quality product. Alternate energy sources like biogas and biomass can be used as fuel in the CRIDA drier.
Critical aspects of impedance spectroscopy in silicon solar cell characterization: A review

Abstract Solar energy generation and utilization is dominated by silicon based solar photovoltaic technology, which has a market share of 80–90% of the solar photovoltaic industry worldwide. The performance indicating parameters of silicon solar cells include power conversion efficiency, series and shunt resistance, ideality factor and built-in potential. These parameters are mostly characterized by DC techniques, which is limited by its insufficiency to identify other important parameters such as interfacial diffusion and transition capacitance and resistive and capacitive components of p-p+ interface of a silicon solar cell. Impedance spectroscopy is considered to be one of the most promising techniques for the characterization of abovementioned performance limiting parameters of a solar cell. In order to address the decoupling of various physical processes associated with different interfaces of a solar cell, quantitative analysis of the impedance spectroscopic data is required. An appropriate mathematical model is frequently used to correlate with the physical performance limiting parameters. This review presents a complete overview of the required mathematical models to analyse impedance spectroscopic data for interfacial processes of silicon solar cell.
Genetic diversity analysis of rice (Oryza sativa) genotypes for seedling characters under saline -alkaline condition

Rice is life for Asians as it provides 43 per cent calorie requirement for more than 70 per cent of the population. The production is often limited by salinity. Understanding of physiological and genetic mechanisms is necessary for a breeding programme to improve crop performance under environmental stresses. Thirty rice genotypes pre-germinated in salinealkaline water (pH-9.60; EC-10.0; SAR-54.32; RSC- 11.51) were placed in plastic cups filled with sterile soil and the stress was imposed upto 21 days. Genetic diversity was estimated based on the observations recorded on germination per centage, vigor index, shoot length, root length, seedling length, root/shoot ratio, seeding dry weight, Na+/K+ ratio. The genotypes were grouped in to five clusters based on the Euclidean coefficient which ranged between 2.09(CSR10 X CSR 13) and 76.29 (IWP X Chettiviruppu). Cluster II was largest (22 genotypes) followed by cluster I (4 genotypes). Genotypes grouped under cluster I showed low Na+/K+ ratio which is an important physiological trait for salinity tolerance. Cluster V (MI 48 & IWP) grouped the susceptible genotypes which had high Na+/K+ ratio. The hybrids thus developed from the genotypes of cluster I & V may express high magnitude of transgressive segregants.

Перспективы использования скелета морских губок семейства Aplysinidae и мезенхимных стромальных клеток в тканевой инженерии

Development of the new types of tissue engineered structures is one of the promising trends of current biotechnology. The study was directed to the assessment of prospects for the application of chitin-based skeletons derived from marine sponges of Aplysinidae family ( Aplysina fulva and Aplysina aerophoba ) for creation of bioengineered constructs based on human me senchymal stromal cells. After cleaning and demineralization procedures, sponge skeletons appeared as three-dimensional macroporous matrices formed by intersecting chitin fibrils. After seeding into chitin-based matrices the cells were attached to the surface of the fibrils and were able to spread and proliferate. Mesenchymal stromal cells within Aplysina fulva differentiated into osteogenic and adipogenic directions under the influence of appropriate inductors. Demineralized skeletons derived from marine sponges of Aplysinidae family could be used as scaffolds for mesenchymal stromal cells which provides new opportunities for the creation of adipose and bone tissue engineered structures.
COVID-19 vaccine hesitancy in eight European countries: Prevalence, determinants, and heterogeneity

We examine heterogeneity in COVID-19 vaccine hesitancy across eight European countries. We reveal striking differences across countries, ranging from 6.4% of adults in Spain to 61.8% in Bulgaria reporting being hesitant. We experimentally assess the effectiveness of different messages designed to reduce COVID-19 vaccine hesitancy. Receiving messages emphasizing either the medical benefits or the hedonistic benefits of vaccination significantly increases COVID-19 vaccination willingness in Germany, whereas highlighting privileges contingent on holding a vaccination certificate increases vaccination willingness in both Germany and the United Kingdom. No message has significant positive effects in any other country. Machine learning-based heterogeneity analyses reveal that treatment effects are smaller or even negative in settings marked by high conspiracy beliefs and low health literacy. In contrast, trust in government increases treatment effects in some groups. The heterogeneity in vaccine hesitancy and responses to different messages suggests that health authorities should avoid one-size-fits-all vaccination campaigns.
A modular european education and training concept in nuclear and radiochemistry

In order to maintain European nuclear operations, expertise in nuclear and radiochemistry (NRC) is of strategic relevance. Besides the obvious needs of NRC skills in the context of nuclear power and assessment of disposal options for nuclear waste there are many other applications. This includes radiologic diagnostics and therapy, unthinkable without radiopharmaceutical chemistry, dating in geology and archaeology, (nuclear) forensics and safeguard operations, radiation protection including radioecological assessments of releases and legacies and last but not least basic research e.g. on super heavy elements. The MEET-CINCH project will counteract the massive lack of NRC expertise by three actions. A teaching package for high schools and a MOOC on NRC for general public are built in order to attract young persons to the NRC field and convey them its fascination and relevance.  Two additional actions focus on vocational training and (university) education. MEET-CINCH will develop completely new education and training approaches based on remote teaching and the flipped classroom concept including and further developing material generated in the CINCH I and CINCH II projects, such as the NucWik platform and the remote controlled RoboLab experiments. MEET-CINCH will provide ECVET course modules in an e-Shop adapted to the needs of end-users which have been surveyed in the previous projects. After the end of MEET-CINCH the e-shop will be continuously operated by the NRC-network as part of a sustainable European Fission Training Scheme (EFTS). 
The consortium includes 13 partners from ten European member states; both academia and nuclear laboratories are represented. All partners are experienced in conducting training and education. Networking on national and European level will be an important part of the project, facilitated by having ENEN as one of the partners and by having structural links with other Euratom projects, the EuCheMS DNRC and the NRC-network.
