Game technology to increase range of motion for adolescents with cerebral palsy: a feasibility study
Authors: Hung Jen-Wen , Chang Yao-Jen , Han Wen-Ying 
Published: July 2016

AbstractBackground:People with cerebral palsy (CP) experience limitations in motor control, strength, and range of motion (ROM). Abnormal movements caused by motor impairments commonly occur in people with CP. Activities of daily living (ADLs) can be seriously affected by insufficient ROM among others. To increase ROM, this study assessed the possibility of training three adolescents with CP using a Kinect-based system in a public school setting.Methods:We gamified the movement training by leveraging the Scratch language and the Kinect2Scratch tool that allowed the therapists to perform individual customization with less technical support. This experiment was carried out according to an ABAB reversal replication design in which A represented the baseline and B represented the intervention phases. Three adolescents in a public special-education school participated in the experiment.Results:Data showed that the three participants significantly increased their shoulder ROM and motivation of engaging in rehabilitation as well, thus improving exercise performance during the intervention phases.Conclusion:Despite that, the game is a promising and highly accepted training tool for school use, currently, it is still error-prone, and the requested support exceeds the support that can be provided by clinical therapists. A technically more robust system, combined with additional attractive games, likely results in higher patient motivation and better compliance. This would reduce the need for parents to motivate their children extrinsically and allow for clinical trials to investigate the effectiveness of the system.
There is more to biometrics than user identification: Making mobile interactions personal, secure and representative
Authors: Buschek Daniel 
Published: July 2016

Abstract
This essay contributes an extended view on user information inferred by personal devices to motivate applications of
biometrics beyond user identification. We unfold a new design space in two parts: First, we take inspiration
from the shared focus on individuality in both biometrics and Belk's Extended Self (ES
Belk, R. W.,
Possessions and the extended self. Journal of Consumer Research, 15(2), 139–168, 1988; Belk, R. W., Extended
self in a digital world. Journal of Consumer Research, 40(3), 477–500, 2013.
). ES describes that people use (digital)
objects to define and reflect on their identities. Following this, we propose that personal devices can use biometrics to
assess individual user attributes and behaviour for three application areas related to the core aspects of ES: privacy and
security (Having), UI personalisation (Doing), digital self-presentation (Being). Second, we propose to view biometrics as
part of a larger class of Implicit Information. Such information is inferred from interactions and sensors to be
used across these application domains. We discuss implications
and limitations of this view.
States with values in the Łukasiewicz groupoid
Authors: Matoušek Milan , Pták Pavel 
Published: July 2016

Abstract
In this paper we consider certain groupoid-valued measures and their connections with quantum logic states. Let ∗ stand for the Łukasiewicz t-norm on [0, 1]2. Let us consider the operation ⋄ on [0, 1] by setting x ⋄ y = (x
⊥ ∗y
⊥)⊥ ∗ (x∗y)⊥, where x
⊥ = 1−x. Let us call the triple L = ([0, 1], ⋄, 1) the Łukasiewicz groupoid. Let B be a Boolean algebra. Denote by L(B) the set of all L-valued measures (L-valued states). We show as a main result of this paper that the family L(B) consists precisely of the union of classical real states and Z
2-valued states. With the help of this result we characterize the L-valued states on orthomodular posets. Since the orthomodular posets are often understood as “quantum logics” in the logico-algebraic foundation of quantum mechanics, our approach based on a fuzzy-logic notion actually select a special class of quantum states. As a matter of separate interest, we construct an orthomodular poset without any L-valued state.
States on symmetric logics: extensions
Authors: Bikchentaev Airat , Navara Mirko 
Published: July 2016

AbstractWe continue the study ofsymmetric logics, i.e., collections of subsets generalizing Boolean algebras and closed under the symmetric difference. We contribute to several open questions. One of them is whether there is á non-Boolean symmetric logic such that all states on it are Δ-subadditive.
Large rigid sets of algebras with respect to embeddability
Authors: Czédli Gábor , Jakubíková-Studenovská Danica 
Published: July 2016

Abstract
Let τ be a nonempty similarity type of algebras. A set H of τ-algebras is called rigid with respect to embeddability, if whenever A, B ∈ H and φ: A → B is an embedding, then A = B and φ is the identity map. We prove that if τ is a nonempty similarity type and 𝖒 is a cardinal such that no inaccessible cardinal is smaller than or equal to m, then there exists a set H of τ-algebras such that H is rigid with respect to embeddability and |H| = 𝖒. This result strengthens a result proved by the second author in 1980.
Compatibility for probabilistic theories
Authors: Gudder Stan 
Published: July 2016

Abstract
We define an index of compatibility for a probabilistic theory (PT). Quantum mechanics with index 0 and classical probability theory with index 1 are at the two extremes. In this way, quantum mechanics is at least as incompatible as any PT. We consider a PT called a concrete quantum logic that may have compatibility index strictly between 0 and 1, but we have not been able to show this yet. Finally, we show that observables in a PT can be represented by positive, vector-valued measures.
Effect of ethanol and plant growth regulators on termination of potato microtuber dormancy
Authors: Wróbel Sławomir , Kęsy Jacek , Treder Krzysztof 
Published: July 2016

Abstract
The duration of dormancy varies significantly among cultivars, but even short dormancy can limit usage of potato microtubers for seed production. The aim of the research was to test efficacy of dormancy breaking by treatment with an aqueous solution of ethyl alcohol, saccharose, gibberellic acid and kinetin (ethanol treatment) in comparison to treatment with aqueous solution of thiourea, daminozide and gibberellic acid (standard treatment). Prolonging the period of microtuber production at the in vitro stage significantly favored the short-ening of the dormancy and facilitated its breaking. While the standard treatment had the strongest effect, the ethanol treatment was slightly less efficient. The statistically significant differences were only observed during the first 13 days after the microtuber treatment. After that time, efficacy of ethanol and standard treatments was similar to control treatment with water. The investigated treatments had no effect on the natural decrease of ABA level in microtubers.

Published: July 2016

Abstract
In order to approach optimal micropropagation of Hypericum perforatum, it will be necessary to optimize shoot proliferation stage in in vitro culture. This study was conducted to investigate the effects of different concentrations of B group vitamins; Thiamine HCl, Pyridoxine HCl, Nicotinic acid (control and 100 fold of MS) and Sucrose (30 and 40 g.l−1) on shoot proliferation. For this purpose, Stems with one node were taken from in vitro shoots and cultured on MS medium. All cultures kept at 16h light/8h photoperiod and 25 ±2 °C in growth chamber. Results showed that the highest number of shoots and leaves were achieved when explants cultured in media containing 40 g.l−1 sucrose with 100 fold of MS vitamins. The highest shoots and leaf length were obtained with medium supplemented with 30 g.l−1 sucrose. Nicotinic acid concentrations had an important role in length of the leaves. The highest number of nodes achieved in the media containing 40 g.l−1 sucrose with both concentrations of Nicotinic acid. After two month growing plantlets, light (LGN) and dark glands number (DGN) were counted. Maximum number of LGN was observed in the media containing 30 g.l−1 sucrose with 100 fold of Thiamine and Pyridoxine. However, The Highest number of DGN achieved in the media containing 40 g.l−1 sucrose with 100 fold of Thiamine or Pyridoxine. Increasing of sucrose and vitamins concentrations were efficiently improved in vitro proliferation and some morphological attributes without negative side effects. Therefore, use of high levels of sucrose and vitamins were useful on micro-propagation of Hypericum perforatum.

AbstractThe use of genetic potential of forgotten plants such as grasspea and arugula is an appropriate strategy for increasing of plants tolerance to environmental stresses. Therefore, in this laboratory study the effects of different levels of osmotic (0, -2, -4, -6, -8, -10, -12 and -14 bar caused by PEG) and salinity (0, 50, 100, 150, 200, 250, 300 and 350 mmol induced by NaCl) stresses were evaluated on germination indices of grasspea and arugula in four separate experiments. Arugula showed a suitable tolerance to osmotic stress, so that its germination percentage and rate at treatment of -10 bar were similar to control. Arugula had 79% germination at osmotic level of -14 bar, but its germination rate at this level was 60% lower than control. In addition, its radicle length until -8 bar and radicle dry weight up to -14 bar were higher than control treatment. However, all levels of salinity stress particularly treatments of more than 100-150 mmol decreased the germination indices of arugula. Germination percentage of arugula in 150 and 200 mmol treatments was 22 and 56% lower than control treatment, respectively. Grasspea had partially suitable tolerance to osmotic stress until -6 bar, but then intensified the reducing trends of its germination indices and finally reached to zero at -14 bar treatment. Moreover, salinity stress especially treatments of higher than 100 mmol decreased all germination indices of grasspea. Overall, arugula was a more tolerant plant especially to osmotic stress; therefore this forgotten plant can be used in agronomic and breeding programs in areas affected by drought stress.

Authors: Bae Kee Hwa , Oh Kyoung Hee , Kim Soo-Young 
Published: July 2016

Abstract
We investigated the effects of sodium hypochlorite (NaOCl) and culture medium on embryo swelling and germination of Calanthe discolor Lindl., and established a method for determining the swelling and protocorm formation of C. discolor seeds via in vitro examination of immature seeds. Treatment of immature seeds with NaOCl greatly enhanced the extent of embryo swelling and protocorm formation of immature zygote embryos compared to seeds without NaOCl treatment. The effects of the culture media were also evaluated with regard to embryo swelling and protocorm formation of in vitro cultured seeds with and without NaOCl treatment. Additionally, the effects of white fluorescent light and red and blue LED lights on seedling growth in in vitro culture were examined. The most suitable condition for seedling growth after 12 weeks of culture was the red LED light with POM medium. These results show effective asymbiotic germination and growth of C. discolor.
From Fearful to Trustful – How Perceived Risk Dimensions in E-Commerce Differentiate between Consumers
Authors: Bertea Patricea Elena 
Published: July 2016

Abstract
The need to segment the market for e-commerce in terms of risk is without doubt of great importance, from a theoretical, but mainly from a managerial point of view. This is why the present study derives a typology of consumers based on six dimensions of perceived risk in online shopping (product, financial, delivery, privacy, social and psychological) and links the resulting risk profiles to several outcome variables. The study is one of the few that offers a new perspective on perceived risk, identifying a two-factor structure: situational risk and individual risk. These two factors were used in a cluster analysis, where four segments were identified: careful consumers, fearful consumers, suspicious consumers and trustful consumers. To offer valuable information for practitioners, these segments are compared in terms of intentions to buy online, online shopping frequency, trust in e-commerce, perceived ease of use, and perceived usefulness of e-commerce. One interesting finding is that suspicious and trustful consumers do not differ in terms of buying intention, even though the difference between them in terms of perceived risk is significant. Implications and further research directions are identified.
Analyzing the Impact of Firm’s Embeddedness in a Centralized Supply Network Structure on Relational Capital Outcomes
Authors: Osman Lokhman Hakim , Ahmad Azhar , Omar Nor Asiah 
Published: July 2016

Abstract
This research looks at the different effects of firms’ network structural positions in an upstream supply network upon the firms’ level of relational capital outcomes. Previous research largely focused on the context of decentralized network structure. However, the supply network is a centralized network because of the existence of the focal firm. The existence of the focal firm may influence the impact of relational capital outcomes. Hence, the objective of this research is to determine the type of network structural positions required to obtain a reasonable relational capital outcome in upstream supply network. This study found that network structural positions, i.e. degree centrality contributed to firms’ level of relational capital trust. Hence, a firm embedded in upstream supply network benefits differently in terms of relational capital through different degree of embeddedness. The firm resources should be re-aligned to match the benefits of the different network structural positions.
A Method for Systemic Risk Estimation Based on CDS Indices
Authors: Gaiduchevici Gabriel 
Published: July 2016

Abstract
The copula-GARCH approach provides a flexible and versatile method for modeling multivariate time series. In this study we focus on describing the credit risk dependence pattern between real and financial sectors as it is described by two representative iTraxx indices. Multi-stage estimation is used for parametric ARMA-GARCH-copula models. We derive critical values for the parameter estimates using asymptotic, bootstrap and copula sampling methods. The results obtained indicate a positive symmetric dependence structure with statistically significant tail dependence coefficients. Goodness-of-Fit tests indicate which model provides the best fit to data.
Evidence on the Nexus Between Electricity Consumption and Economic Growth through Empirical Investigation of Uganda
Authors: Sekantsiand Lira , Motlokoa Mamofokeng 
Published: July 2016

Abstract
This paper empirically examines the electricity consumption - economic growth nexus in Uganda for the period 1982 to 2013, with a view to contributing to the body of literature on this topic and informing energy policy design in Uganda. Using capital stock as an intermittent variable in the causality framework, the paper employs Johansen-Juselius (1988, 1995) multivariate cointegration and VECM based Granger causality tests and finds a bidirectional causality between electricity consumption and economic growth in the long-term and distinct causal flow from economic growth to electricity consumption in the short-run, and short-term and long-term Granger causality from capital stock to economic growth, with short-run feedback in the opposite direction. Therefore, it implies that firstly, the Government of Uganda (GoU) can implement conservation policies only through reducing energy intensity and promoting efficient energy use to avoid decline in output and secondly, that the GoU should intensify its efforts towards capital accumulation in order to realize sustainable economic growth. Lastly, the empirical evidence that electricity consumption influences some short-term capital accumulation supports the GoU’s efforts to allow private sector investment in the electricity sector in an effort to increase electricity supply.

Authors: Pandey Satyendra C , Pattnaik Pinaki Nandan 
Published: July 2016

Abstract
The aim of this paper is to propose a new theoretical perspective and a conceptual model to build a sustainable research ecosystem in universities. The paper is conceptual in nature and draws upon existing literature to propose a unique framework on sustainable research ecosystem. This paper borrows the theoretical foundations from natural ecosystem to propose a process and stakeholder view of a research ecosystem in universities and suggests means to achieve sustainability in the long run. A thriving university research ecosystem leads to consistency, efficiency and sufficiency in research output. The ideas proposed in this paper are in the nascent stage and in the emerging market context. Future research is suggested to operationalize and validate the proposed framework in both developing and developed nation context. The insights generated here would therefore contribute to the existing models and frameworks that few universities subscribe to. From an originality point of view present work has conceived and conceptualized a new direction of thinking, i.e. creation of a sustainable research ecosystem.
Investigation on the Causal Relationship between Inflation, Output Growth and their Uncertainties in Romania
Authors: Pintilescu Carmen , Asandului Mircea , Viorică Elena-Daniela , Jemna Dănuţ-Vasile 
Published: July 2016

Abstract
Based on monthly-recorded data for the 1990-2014 period related to output growth and inflation, we use heteroskedastic models in order to estimate the nominal and real uncertainty in Romania. Real uncertainty is derived from output growth volatility and nominal uncertainty is derived from inflation volatility. Of the 12 possible hypotheses regarding causal relationships between output growth, inflation, nominal uncertainty and real uncertainty, we consider 7 hypotheses for which we find strong theoretical arguments and empirical evidence in literature. In order to ensure the robustness of the results, the Granger-causality tests are performed for 4, 8 and 12 lags, which are then used to test 7 economic hypotheses.
Modeling of transport phenomena in fixed-bed reactors for the Fischer-Tropsch reaction: a brief literature review
Authors: Sánchez-López José R.G. , Martínez-Hernández Angel , Hernández-Ramírez Aracely 
Published: July 2016

Abstract
Currently, few processes can be considered practical alternatives to the use of petroleum for liquid fuel production. Among these alternatives, the Fischer-Tropsch synthesis (FTS) reaction has been successfully applied commercially. Nevertheless, many of the fundamentals of this process are difficult to understand because of its complexity, which depends strongly on the catalyst and the reactor design and operating conditions, as the reaction is seriously affected by mass and heat transport issues. Thus, studying this reaction system with transport phenomena models can help to elucidate the impact of different parameters on the reaction. According to the literature, modeling FTS systems with 1D models provides valuable information for understanding the phenomena that occur during this process. However, 2D models must be used to simulate the reactor to correctly predict the reactor variables, particularly the temperature, which is a critical parameter to achieve a suitable distribution of products during the reaction. Thus, this work provides a general resume of the current findings on the modeling of transport phenomena on a particle/pellet level in a tubular fixed-bed reactor.

Abstract
Mason, BRJ, Argus, CK, Norcott, B, and Ball, NB. Resistance training priming activity improves upper-body power output in rugby players: implications for game day performance. J Strength Cond Res 31(4): 913–920, 2017—“Priming” or preactivation strategies performed in the hours leading into competition have been suggested to improve game day performance. Therefore, this study assessed the effectiveness of a resistance training priming activity on eliciting changes in lower- and upper-body power output, along with perceptual measures. To assess these changes, 13 state-level rugby players (aged 18.5 ± 0.5 years) completed a test–retest protocol using a counterbalanced crossover design. Perceptual (readiness to perform questionnaire) and performance measures (20-kg countermovement jump [CMJ], 20-kg bench throw) were completed before either a control (rest) or priming activity (4 sets of 3 banded back squats and banded bench press). After a 1-hour and 45-minute recovery period, perceptual and performance measures were repeated. Readiness to perform showed no meaningful differences pre- and postintervention. Bench throw peak power (8.5 ± 5.8%, 90% confidence limit; p ≤ 0.05) improved after the priming activity when compared with the control trial. Countermovement jump peak power (3.4 ± 4.9%; p > 0.05) had a small decrease after the priming activity when compared with the control trial. Therefore, completing a priming activity 1 hour and 45 minutes before competition is recommended to improve upper-body power output. However, further research into lower-body priming protocols should be conducted before implementing a lower-body priming activity before competition.
