Feature determination from powered wheelchair user joystick input characteristics for adapting driving assistance
Authors: Gillham Michael , Pepper Matthew , Kelly Steve , Howells Gareth 
Published: December 2017

Background: Many powered wheelchair users find their medical condition and their ability to drive the wheelchair will change over time. In order to maintain their independent mobility, the powered chair will require adjustment over time to suit the user's needs, thus regular input from healthcare professionals is required. These limited resources can result in the user having to wait weeks for appointments, resulting in the user losing independent mobility, consequently affecting their quality of life and that of their family and carers. In order to provide an adaptive assistive driving system, a range of features need to be identified which are suitable for initial system setup and can automatically provide data for re-calibration over the long term. Methods: A questionnaire was designed to collect information from powered wheelchair users with regard to their symptoms and how they changed over time. Another group of volunteer participants were asked to drive a test platform and complete a course which represented manoeuvring in a very confined space as quickly as possible. Two of those participants were also monitored over a longer period in their normal home daily environment. Features, thought to be suitable, were examined using pattern recognition classifiers to determine their suitability for identifying the changing user input over time. Results: The results are not designed to provide absolute insight into the individual user behaviour, as no ground truth of their ability has been determined, they do nevertheless demonstrate the utility of the measured features to provide evidence of the users’ changing ability over time whilst driving a powered wheelchair. Conclusions: Determining the driving features and adjustable elements provides the initial step towards developing an adaptable assistive technology for the user when the ground truths of the individual and their machine have been learned by a smart pattern recognition system.

Published: December 2017

Abstract: This study proposes improving the understanding of the main aspects involved in the design of warehouses by the construction of a framework that reveals the state-of-art. The initial research bibliography generated a framework, which was structured in three dimensions: inputs; design and implementation; and outputs. The validation of framework was accomplished through a systematic review of the literature, covering 68 articles published in the period 1999- 2015. This study covered the main aspects highlighted in the academic literature that influence the design of warehouses. Additionally, an overview of the publications based on a theoretical/empirical and a quantitative/qualitative approach was pointed out. This paper aims to contribute to both industry and academic. On the one hand, the framework aggregates value for professionals by permitting the rapid identification of variables, which must be considered in warehouse design. On the other hand, by systematizing the warehouse design area, researchers are able to identify gaps that may generate future studies.

AbstractBioactive glasses (BG) are known for their ability to induce bone formation by the action of their dissolution products. Glasses can deliver active ions at a sustained rate, determined by their composition and surface area. Nanoporous sol-gel derived BGs can biodegrade rapidly, which can lead to a detrimental burst release of ions and a pHrise. The addition of phosphate into the glass can buffer the pH during dissolution. Here, dissolution of BG with composition 60 mol% SiO

Published: December 2017

Abstract
Cloud computing technology has transformed the information and communication technology industry by authorizing on-demand resource delivery to the cloud users. Datacenters are the major resource storage places from where the resources are disseminated to the requesters. When several requests are received by datacenters, the available resources are to be handled in an optimized way; otherwise the datacenters suffer from resource wastage. Virtualization is the technology that helps the cloud providers to handle several requests in an optimized way. In this regard, virtual machine placement, i.e., the process of mapping virtual machines to physical machines is considered to be the major research issue. In this paper, we propose to apply fuzzy hybrid bio-inspired meta-heuristic techniques for solving the virtual machine placement problem. The cuckoo search technique is hybridized with the fuzzy ant colony optimization and fuzzy firefly colony optimization technique. The experimental results obtained show competing performance of the proposed algorithms.
“I Cannot Dance Upon My Toes”: A Case Study Into Teacher Learning Through Participating in an English Teaching Contest in China
Authors: Yueting Xu 
Published: December 2017

AbstractThe professional development of College English (CE) teachers in China has received considerable attention due to their responsibility in preparing university graduates for adequate English proficiency. Many continuous professional development (CPD) activities have been conducted (e.g., national teaching contest) to improve CE teachers’ teaching effectiveness, an essential component of teacher learning. However, it has remained unknown concerning how teacher learning takes place in these well-intended CPD activities, and what mediating factors play an important role in teacher learning. To address this gap, this case study reports on a CE teacher’s (Janna, pseudonym) experience in preparing for and participating in an English teaching contest. Drawing upon multiple sets of data such as teacher reflective journals, interviews, observations of group discussions, and video-recorded teaching demonstration and lesson plan presentation, the findings reveal that teacher learning takes place at a superficial level through legitimate peripheral participation, yet at a deeper level through identity crisis. Vulnerable teacher learning is also identified in the CPD activity, with differentiated learning possibilities created by the tensions between resources and power relations within the community and the teacher’s conceptions of teaching and learning. The study concludes with implications for research of teacher learning and practice for teacher professional development.
When Teacher Autonomy Meets Management Autonomy to Enhance Learner Autonomy
Authors: Yi Wang 
Published: December 2017

AbstractDeveloping learner autonomy (LA) requires a shift of control from teachers to students. This development also relates to teacher autonomy (TA), which requires school managers to relinquish some degree of their own autonomy (MA) to teachers. Thus, a problem arises: how can the three levels of control-shifts co-exist and survive in harmony, and ideally, thrive each in its own way? Based on a recent case study, this paper aims to explore the complexity of the dynamic interaction between these three types of autonomy within an educational hierarchy. The study was conducted in a Chinese secondary school which was promoting whole-person development through a comprehensive innovation project. The participants comprised nine English teachers, the executive director, and the principal. Data collection methods included interviews, observations, and post-lesson discussions. Three issues are addressed in this paper: the principal ’s perceptions of LA, a classroom instruction model to cultivate LA, and a teacher training scheme to facilitate TA. The findings display a complex picture of these issues, and imply the importance of a genuine, shared understanding of the nature of autonomy and the need to carefully ensure the optimal balance among the three types of autonomy in the design and implementation of curriculum innovations.
Distribution and Size of Barnacle Chelonibia patula Fouling Blue Crab Callinectes amnicola in Southeast Nigeria
Authors: Udoh James Philip , Otoh Aniekan Johnny 
Published: December 2017

Abstract
The distribution and occurrence of epibionts on the dorsal carapace, ventral carapace and chela of 325 specimens of Callinectes amnicola (De Rocheburne, 1883) (103.4 - 138.7 mm carapace width) from the Qua Iboe (QIRE) and Imo River (IRE) estuaries in southeast Nigeria was determined. The only ectosymbiont observed was cirriped barnacle, Chelonibia patula, mostly of smaller sizes (2.25 mm), infesting only 25-29% of intermoult crabs, more on females and in the Imo River estuary, with an average of four barnacles per crab, presupposing low level of epibiont-host interaction. There was no significant difference (P>0.05) in spatial distribution but epibionts were highest in the dry season in low salinity IRE (0.53‰) and in wet season in the medium-salinity QIRE (17.4‰). No public health risk has been reported among crab consumers in the study area. This study highlights epibiont-host interaction in the study area largely unknown for proper management of the fishery.
Fisheries and Climate Change: Inevitability or Prophylaxis? Contributing to a Necessary Debate
Authors: Monteiro Pedro Valadas 
Published: December 2017

Abstract
Climate changes constitute the greatest challenge of this century due to the modifications they cause in weather and environmental conditions, and thus affecting the social and economic dynamics at multiple levels. Because all invertebrates and fish used for human consumption are poikilotherms, they are very sensitive to modifications in the environment, namely temperature and levels of oxygen. Phenomena like temperature rising, acidification, ocean stratification and changes in salinity are already perceptible and susceptible of causing severe consequences in aquatic ecosystems. Falling productivity, species migration and localized extinctions, as well as conflict over the use of scarce resources and increased risks associated with more extreme climatic events are among the possible consequences. Increased climate variability justifies a focus on the design and promotion of strategies to control the inherent risk and increase the resilience of marine and freshwater systems that strongly affect the livelihoods of millions of human beings worldwide. A multidimensional and holistic concept for the sustainable management of maritime and marine resources is indissociable from the unequivocal evidence of climate changes. Raising awareness of public in general and ocean stakeholders for the relevance of the topic at hand are assumed as key dimensions with the present article.

Abstract
The objectives of this study were to investigate the length-weight relationship and condition factor of crayfish living in the natural habitat of South Sorong and Jayawijaya Regencies, Papua, Indonesia. Three species of crayfish (Cherax monticola, C. albertisii and C. communis) were collected from Jayawijaya Regency and only one species of crayfish (C. swonden) was collected from South Sorong Regency. The growth coefficient (b) for each crayfish species ranged from 2.55 to 3.10. C. monticola from Jayawijaya Regency presented the highest b value (3.10), and C. swonden from South Sorong Regency showed the lowest b value (2.55). The condition factors (K) for each crayfish species ranged from 1.9 to 2.3. C. monticola and C. albertissi had the highest K value (2.3), whereas C. swonden demonstrated the lowest K value (1.9). The present study indicated that the values of b and K of crayfish living in Jayawijaya were higher than those from South Sorong probably because Jayawijaya habitat provides more suitable environment and better food supply for crayfish than South Sorong.

The Reform of French Contract Law: An Analysis of its Application to Corporate Acquisitions
Authors: Barrière François , Bine Pascal , Diaz Olivier 
Published: December 2017

AbstractMore than ten years after the French President at the time first announced it – during the bicentenary celebration of the Napoleonic Code, the reform of the law of contracts has taken shape. The reform’s objectives are to make the law more accessible while increasing legal certainty; objectives often put forward during successive legal reforms without necessarily being met. Its purpose is also to increase the efficiency of French contract law, which will encourage business growth, and is evident, for instance, by the fact that unilateral will is being dealt with several times in the reform. In addition, contractual freedom, captured within the preliminary provisions, sets the tone for a more flexible legal framework. Although the reform codifies several solutions derived from case-law, it also introduces noteworthy innovations such as, in particular, a duty to inform, a legal framework for unforeseeable situations, means of action against unfair clauses in adhesion contracts, or even the ability to reduce the price in the event of incomplete performance of the contract. This reform recognizes contractual freedom, which can – in any event – only be a step in the right direction! This article analyses the modification to French contract law made by Ordinance N° 2016–131 and their impact on corporate acquisitions.
The Birth of the Prison: The Functions of Imprisonment in Early Mesopotamia
Authors: Reid John Nicholas 
Published: December 2017

AbstractWhile the terms prison and prisoner are frequently used in translations and studies based on the texts from early Mesopotamia (ca. 3200–1595 B.C., according to Middle Chronology),Although “early Mesopotamia” is not ideal as a descriptor, it is employed here in the same way as Postgate (1992: xxi–xxiii). The term is used to refer to Southern Mesopotamia from Late Uruk until the first fall of Babylon, or circa 3200–1595 B.C. Despite this, the Mari evidence will be summarized and referenced at certain points in the article. While the focus of this study is in on the early Mesopotamian evidence, occasional references are made to select relevant material from other periods to add depth and perspective to the discussion.the contextual evidence relating to these terms has not been assembled and organized to determine the nature of the so-called prisons of the period, together with any points of continuity and discontinuity with the modern terminology. When done, it may be concluded that prisons in early Mesopotamia do not share a one-to-one correspondence with the various manifestations of prisons in the modern Western world. Although prisons in early Mesopotamia functioned in broader ways than modern examples, I argue that significant functional overlap also exists. These similarities directly relate to theoretical and definitional criteria employed in historical discussions about prisons, demonstrating that the Mesopotamian evidence belongs in a world history of prisons.
Does Banknote Quality Affect Counterfeit Detection? Experimental Evidence from Germany and the Netherlands
Authors: van der Horst Frank , Eschelbach Martina , Sieber Susann , Miedema Jelle 
Published: December 2017

Abstract
Counterfeit prevention is a major concern for central banks. In search of effective policy measures, it is often claimed that a clean banknote circulation helps the general public to more easily detect counterfeits. To examine this claim, we conducted an experimental study with 250 consumers and 261 cashiers in the Netherlands and Germany. Participants received 200 banknotes with either a high or a low average soil level. The banknote test sets contained 20 counterfeits to be detected by the participants. For the regression analysis we applied approaches used in the area of psychophysical science (signal detection theory). Our candidates identified more counterfeits when sorting clean banknotes. However, our analysis also showed that the cleanliness of banknotes does not actually help the person checking the banknote to more easily distinguish a counterfeit banknote from a genuine note. In fact, new and clean banknotes raised suspicion: they were more often declared as counterfeits – correctly or not. We discuss the implication of our results for central banks’ banknote policies.
al_o dv kie_en maht an dirre figuren: Formen und Funktionen astronomischer Diagramme in der sogenannten ‚Mainauer Naturlehre‘
Authors: Lindemann Dorothee 
Published: December 2017

AbstractThe present study adverts to a newly found manuscript and reclassifies the diagrams of the ‘Mainauer Naturlehre’ in the context of the Latin tradition. Thus, a deficit of research concerning the astronomic technical literature in Middle High German can be closed. The Basle vernacular manuscript that is discussed here shows a very strong relationship between the text and its diagrams, which is examined as a special kind of diagrammatical act, whose intratextual function lies primarily in the realm of historical semantics: the diagram generates a notion of scientific specialization in vernacular. In contrast to this, the York manuscript confronts text and diagram in a contrapunctual way and supplements the vernacular text with an appendix of Latin diagrams. This relation between German prose and Latin diagrammatic tradition might well be a reflection of a pragmatic background.
Theoretical Simulation of a Room Temperature HgCdTe Long-Wave Detector for Fast Response − Operating Under Zero Bias Conditions
Authors: Martyniuk Piotr , Kopytko Małgorzata , Madejczyk Paweł , Henig Aleksandra , Grodecki Kacper , Gawron Waldemar , Rutkowski Jarosław 
Published: December 2017

AbstractThe paper reports on a long-wave infrared (cut-off wavelength ~ 9 μm) HgCdTe detector operating under nbiased condition and room temperature (300 K) for both short response time and high detectivity operation. The ptimal structure in terms of the response time and detectivity versus device architecture was shown. The response time of the long-wave (active layer Cd composition, xCd= 0.19) HgCdTe detector for 300 K was calculated at a level of τs~ 1 ns for zero bias condition, while the detectivity − at a level of D* ~ 109cmHz1/2/W assuming immersion. It was presented that parameters of the active layer and P+barrier layer play a critical role in order to reach τs≤ 1 ns. An extra series resistance related to the processing (RS+in a range 5−10 Ω) increased the response time more than two times (τs ~ 2.3 ns).
Lexical Substitution and Paraphasia in Advanced Dementia of the Alzheimer Type
Authors: Ovchinnikova Irina , Pavlova Anna 
Published: December 2017

Abstract
The paper presents the case study of lexical selection in Alzheimer-type dementia. Lexical substitutions in poem recitation and conversations of a Russian speaker, who suffered Alzheimer-type dementia, were analyzed on the background of the lexical retrieval and slip-of-the-tongue phenomena. The classification of the substitutions is worked out on the basis of the links between a target word and its substitutions. The current context plays an essential role as natural priming for a substitution in a poem recitation. Some words have predisposition to be lost; the units belong to the figurative language or to the category of infrequent lexemes. In conversation, the patient masked failures by referring to the circumstances and appealing to the sense of humor. Positive emotions facilitate recollecting of words, involved in the description of real-life events, due to the relatively spared nondeclarative memory. The changes in the substitutions and paraphasias categories between AD stages are statistically significant.
Investigation of chemical composition and moisture content for different materials on the attenuation of γ rays
Authors: Hilal Moustafa A. , Attallah Mohamed F. 
Published: December 2017

Abstract
In the present work, materials, namely mud, sand mud, ferruginous sandstone and sandstone with different densities are used to evaluate the effect of chemical composition and moisture content on the self-attenuation coefficient factor at γ-energy range from 59.5 to 1332.5 keV. The results revealed that the attenuation coefficient increases with increasing the moisture content until the material saturate with moisture. The average value of increasing linear attenuation coefficients based on increasing moisture content are 14.3%, 16.0%, 18.2%, 28.1% and 24.8% at γ-energies 59.5, 356.0, 661.7, 1173.4 and 1332.5 keV, respectively. Chemical composition of material affected on the values of attenuation, i.e. the elements with high density have high attenuation coefficient. Significant effect of self-attenuation correction factor was observed at low γ-energies up to 500 KeV. Application of the calculated correction of environmental sample with low radioactivity content has been carried out.
