User-Defined Gestures for Dual-Screen Mobile Interaction

ABSTRACT Existing mobile phones use the front screen for gesture interactions, but they often suffer from usability problems such as content occlusion and spurious triggering caused by fat finger errors. Recent advances in new sensor technologies have made it possible for modern mobile phones to recognize gesture inputs on the rear screen. Although inputs from the backside of a mobile phone have demonstrated their usefulness for simple interaction tasks such as target acquisition, little is known regarding the best practices in gesture design for complex concurrent tasks on dual-screen mobile devices. Therefore, we conducted a three-stage study to explore user-defined multi-finger gestures for concurrent game tasks on a dual-screen mobile device. Experimental results indicate the existence of a consensus between participants regarding gesture choices for specified game tasks. Based on this consensus, we developed a gesture taxonomy and generated a set of user-defined gestures for dual-screen mobile devices. A subsequent benchmark test validated the popularity of the user-defined gestures with both ordinary and professional game players.
Occurrence of FOX AmpC gene among Pseudomonas aeruginosa isolates in abattoir samples from south-eastern Nigeria

ISSN In Nigeria, several investigations have been done about the prevalence of the AmpC enzyme in clinical isolates of Gram-negative bacteria; however, little information is available on the occurrence rate of this important enzyme in abattoir specimens that play a major role in the environmental pollution in Nigeria. This study aimed to evaluate the presence of FOX AmpC-producing Pseudomonas aeruginosa isolates from abattoir samples by both phenotypic method and polymerase chain reaction (PCR). In this study, 360 abattoir samples were analyzed for the isolation of P. aeruginosa strains. Antibiogram was carried out using the disk diffusion technique. The production of AmpC enzymes was phenotypically screened and confirmed using the cefoxitin–cloxacillin double-disk synergy test (CC-DDST). Finally, gene responsible for FOX AmpC enzyme production was investigated using PCR. A total of 147 (40.8%) isolates of P. aeruginosa was recovered from the abattoir samples. Ceftazidime and ciprofloxacin with 45.6 and 19% of susceptibility rates were the most and the less effective antibiotics, respectively. A total of 24 (16.3%) P. aeruginosa isolates were confirmed to phenotypically produce AmpC enzyme. However, the PCR result showed that only three (12.5%) of P. aeruginosa isolates harbored the FOX AmpC gene suggesting the attendance of other AmpC resistance genes. This study reported the first occurrence of P. aeruginosa isolates harboring the FOX AmpC gene in abattoir samples from south-eastern Nigeria. This incident requires the adoption of new policies and measures to prevent the further spread of strains carrying the AmpC gene. Copyright 2020 Wolters Kluwer Health, Inc. All rights reserved.
Steel column stability and implications in the seismic assessment of steel structures according to Eurocode 8 Part 3

Seismic performance assessment of new and existing steel structures based on nonlinear static (pushover) analysis necessitates the use of engineering‐oriented models that trace the nonlinear response of structural steel elements under static and cyclic loading. Recent experiments and corroborating finite element simulations on I‐ and H‐shaped steel columns constitute an important data source for such a development. This paper presents important insights regarding the behaviour of steel columns under cyclic and monotonic loading based on an assembled steel column database. We propose simple, yet accurate, practice‐oriented models to predict the strength and deformation capacities at yield and ultimate rotation (near collapse) of steel columns within the framework of Eurocode 8 Part 3 (EC8‐Part 3). The proposed models are derived from first principles of mechanics along with robust statistical approaches leveraging the assembled datasets. It is shown that modelling provisions for steel columns in the current EC8 Part 3 do not reflect column behavioural trends from the available databases. The influence of loading history on the derived modelling recommendations for columns is also quantified and discussed. The proposed recommendations may be incorporated in future versions of EC8‐Part 3 for seismic performance assessment of new and existing steel structures.
Effect of Blending Ratio on the Fuel Properties of Almond Biodiesel

Since almond seed oil can be used for biodiesel production, this study is aimed at investigating the effect of different blend ratios on the fuel properties of almond biodiesel. The biodiesel was characterized for the properties of flash point, cloud point, pour point, viscosity, saponification value, peroxide value, acid value, iodine value, density and specific gravity using the Gas Chromatography Mass Spectrophotometer (GCMS). When blended with petrol diesel at ratios of 20%, 30% and 50%, results showed that the properties of the biodiesel obtained at a blend of 20% had properties more similar to the ASTM standard. At that proportion of 20%, the properties of acid value, viscosity, cloud point, pour point and iodine value were found to be 0.95meq/kg, 8.80Cp, 60C, 10C and 41.62gI2/100g respectively, except the flash point which was 720C at biodiesel blend of 50%. This is because increase in blending ratios was found to result in corresponding increase of the properties.
FACTORS AFFECTING STUDENTS’ ACADEMIC PERFORMANCE IN FINANCIAL REPORTING COURSE USING FRAMEWORK-BASED TEACHING APPROACH

Students’ performance (academic achievement) is fundamental in producing quality graduates. Many empirical studies are conducted to investigate factors affecting university students’ performance. The focus of this study is to measure the relationship between students and lecturers interaction, lecturers’ characteristics and lecturers’ knowledge and performance in financial reporting course using Framework-based Teaching Approach. The present study prefers a survey method. Questionnaires are used as an instrument in this study and are distributed to students taking Advanced Financial Accounting and Reporting 1 (FAR610) during semester March-July 2017 at Faculty of Accountancy, Universiti Teknologi Mara Puncak Alam, Malaysia. Data were randomly selected dan analyzed using Statistical Package for Social Science (SPSS). Based on the response from 91 students, the results show that only lecturers’ knowledge is positive and significantly related to financial reporting performance. The students and lecturers interaction and lecturers’ characteristics do not relate to the students’ performance in financial reporting course. The result could facilitate lecturers to understand and find new ways that may be applied at the beginning of the course to improve students’ performance.
Bequests, Imperfections in Factor Markets, and Long-Run Inequality: A Theoretical Assessment of Piketty

The book Capital in the Twenty-First Century by Thomas Piketty (2014) has renewed the public and scholar debate about wealth and income inequality. Theoretical critiques have focused their attention on a regularity pointed out by the author, namely, the growth rate of the economy is lower than the interest rate, r > g. However, two other important insights are key to understand the persistence of inequality: bequests and differences between factor prices and the marginal productivity of factors. We present an OLG model that incorporates these two elements and explores under which circumstances inequality between two social groups, rich dynasties and poor dynasties, is a long-term equilibrium result with economic growth. The model considers two goods, one essential and the other non-essential. We find that inequality between rich and poor dynasties is a long-term equilibrium when (i) the marginal productivity of labor of the essential good is bounded from above and the marginal productivity of capital in the non-essential good sector is bounded from below by a positive value; and (ii) factor remunerations are not determined by the standard economic forces of marginal product.
Adakitic rocks and A‐type felsic dykes in the Changlingzi area, NE China: Constraints on multistage tectonism in the southern Great Xing'an Range

New LA–ICP–MS zircon U–Pb geochronology, whole‐rock major and trace element geochemistry data, and petrographic observations are presented for three granitic dykes in the Changlingzi area of NE China. These data provide precise age and petrogenesis information with respect to the late Palaeozoic–Mesozoic intrusions in the area, which further constrain the geodynamic evolution of the southern Great Xing'an Range. Our zircon U–Pb data denote that the felsic dykes were emplaced during the Late Permian (~254 Ma) and Late Jurassic (143–142 Ma). Geochemically, the Late Permian monzonite porphyries are characterized by high Al2O3 (16.52–16.92 wt%) and Sr (490–579 ppm) contents and low Yb (0.52–0.57 ppm), Y (5.7–6.3 ppm), and heavy rare earth element (HREE) contents, which indicate an adakitic affinity. The Late Jurassic felsic dykes are characterized by high FeOt/MgO (8.2–11.9) and Ga/Al (3.3–3.8) ratios, high zircon saturation temperatures (888–929°C), and remarkable negative Eu (Eu/Eu* = 0.25–0.42) anomalies, indicating they are akin to A‐type granites. The Late Permian adakitic magma resulted from the partial melting of thickened lower crust, and was formed during collisional orogenesis related to subduction of Palaeo‐Asian Ocean crust. The Late Jurassic A‐type magmas were probably generated by the partial melting of amphibolite‐facies lower crustal materials. The melting occurred in response to the upwelling of asthenospheric material caused by collapse of thickened crust, due to gravitational instability during closure of the Mongol–Okhotsk Ocean. Subsequently, the latest stage of magmatic activity in this area and elsewhere in NE China was controlled mainly by subduction of Palaeo‐Pacific Ocean crust.
A Decomposition-Based Local Search for Large-Scale Many-Objective Vehicle Routing Problems With Simultaneous Delivery and Pickup and Time Windows

Vehicle routing problem with simultaneous delivery and pickup and time windows (VRPSDPTW) is an important logistics problem in supply chain network optimization. However, at present, existing approaches are only applied to solve small-scale many-objective VRPSDPTW. For the large-scale problem, to obtain high-quality solutions (effectively) and solve the problem in a short running time (efficiently), we focus on two issues: 1) how to handle many-objective property and 2) how to tackle large-scale property of the problem. For the first issue, to enhance the convergence property, a novel local search algorithm utilizing seven neighborhood operators is proposed. Meanwhile, to maintain the diversity property, the concept of decomposition is adopted. The problem is first decomposed into multiple single-objective problems, then local search is utilized to optimize these subproblems. For the second issue, since optimizing a subproblem by local search is time consuming for large-scale problems, the key point is how to allocate the computational resources and balance the convergence and diversity. To handle this problem, a weight space partition strategy is introduced. Finally, a decomposition-based local search algorithm is proposed for many-objective VRPSDPTW. Experimental results on the large-scale instances provided by Chinese logistic company show the effectiveness of the proposed algorithm.

The effect of cognitive and behavioral factors on student success in a bottleneck business statistics course via deeper analytics

Abstract In this article, we study a set of factors underlying student success in a bottleneck business course using statistical and data mining techniques. Factors included learning styles, motivational and other cognitive factors, personality traits, learning analytics, along with background demographic and academic ones. Our analysis yielded interesting insights that show some of these factors play significant roles in predicting both student performance and their propensity to utilize resources that help improve their performance, such as additional support services. The predictive accuracy of both of our models were over 95% (error rate <5%). Moreover, quantile regression models were used to determine factors that specifically affect the performance of low-performing students so that targeted intervention and support services can be developed specifically for them. In conclusion, deeper analytics via statistical models are crucial for forming an in-depth understanding of how to improve student performance in a bottleneck course and this has far-reaching implications for both educators and administrators in higher education.
Comparison of cloud systems simulated with two-dimensional and three-dimensional cloud resolving models

Two-dimensional (2D) and three-dimensional (3D) cloud resolving models (CRM) are some of the best tools that can be used to simulate convective cloud systems and their properties relative to larger scale models. But, when attempting to understand when a certain type of CRM should be used, previous studies on the effects of dimensionality within CRMs have returned conflicting results. Equivalent 2D and 3D CRMs were used to produce 30-day simulations of the Madden-Julian Oscillation (MJO) during the first month of the Dynamics of the Madden-Julian Oscillation (DYNAMO) field campaign (October 2011) to study the effects of dimensionality to increase understanding of convective cloud processes and the processes behind the MJO. The MJO is a 30 – 90 day oscillation that occurs in multiple rainy and dry phases within the Eastern Indian and Western Pacific Ocean, but the mechanisms as to why it occurs is relatively unknown. By using CRMs to simulate cloud systems during the MJO, results can provide insight into one of the main theories of the MJO, the building block theory, which is based on cloud formation and organization. The simulations are broken down into suppressed (dry) and active (rainy) MJO phases; precipitating clouds are further separated based on convective precipitation and nonconvective precipitation gain further understanding of the difference in weak and strong convection. Differences between the twoand threedimensional models during the suppressed MJO phase are shown to be small mainly due to a lack of strong forcing or convection. The 3D model is slightly drier during this time, but it does produce more precipitation than the 2D model. Differences are shown to be larger during the active phase of the MJO, especially in the cloud
Partisan politics of skills in middle-income countries: Insiders, outsiders and the vocational education system of Turkey

The literature on the political economy of development argues that many middle-income countries could not develop strong vocational education and training systems because of the lack of political coalitions that would support such systems. However, these researchers have overlooked the role of partisan politics, domain of political competition and the links of insiders and outsiders with political parties. This article addresses this gap by studying the case of Turkey in the 2000s, when the country was governed by the Justice and Development Party and experienced important changes in its vocational education and training system. It investigates the political shifts in these years and the impact of these shifts on vocational education and training policies. The article argues that the governing Justice and Development Party played a key role in the changes in the Turkish vocational education and training system. Small and medium enterprises and labour market outsiders, which were the outsiders of the political and economic system, formed Justice and Development Party’s main constituents. Different from the previous parties, Justice and Development Party focused on the economic interests of outsiders and vocational education and training became an important tool to address such interests of both groups. The Justice and Development Party governments integrated the interests of both small and medium enterprises and workers into the vocational education and training policies in the 2000s, which has led to a vocational education and training system with high state commitment, higher firm involvement and higher permeability between vocational and general education. This research is based on process-tracing of the political dynamics and vocational education and training system developments in Turkey in 2002–2011. The data comprise primary and secondary documents, as well as interviews with several stakeholders.
Exploring learners’ grammatical development in mobile assisted language learning

Abstract This study reports the results of a mixed methods approach to investigate the impact of instructor feedback in mobile-assisted language learning (MALL) on the grammatical development of English as a foreign language (EFL) learners. The participants of this quasi-experimental study included 40 female EFL learners randomly selected from the English learning chat groups on Telegram, an online instant messaging application. Dialang, a free web-based language proficiency test, was used to assess the learners’ grammatical knowledge as pre-test on the basis of which the participants in the experimental group were categorized into 15 chat groups, each including the instructor and two participants of the same level of proficiency in English grammar. A paired samples t-test was utilized to analyze the quantitative data. The results indicated that using chats in Telegram led to a significant development in learners’ grammatical accuracy in the experimental groups. Semi-structured interviews were conducted to explore the learners’ attitudes towards their experience in MALL immersion program. The thematic analysis used to analyze the qualitative data revealed a number of themes which addressed the learners’ positive perceptions towards using MALL applications to develop their grammatical structures in online chats.

On constant solutions of SU(2) Yang-Mills equations with arbitrary current in Euclidean space ℝn

In this paper, we present all constant solutions of the Yang-Mills equations with SU(2) gauge symmetry for an arbitrary constant non-Abelian current in Euclidean space ℝn of arbitrary finite dimension n. Using the invariance of the Yang-Mills equations under the orthogonal transformations of coordinates and gauge invariance, we choose a specific system of coordinates and a specific gauge fixing for each constant current and obtain all constant solutions of the Yang-Mills equations in this system of coordinates with this gauge fixing, and then in the original system of coordinates with the original gauge fixing. We use the singular value decomposition method and the method of two-sheeted covering of orthogonal group by spin group to do this. We prove that the number (0, 1, or 2) of constant solutions of the Yang-Mills equations in terms of the strength of the Yang-Mills field depends on the singular values of the matrix of current. The explicit form of all solutions and the invariant F2 can always be written using singular values of this matrix. The relevance of the study is explained by the fact that the Yang-Mills equations describe electroweak interactions in the case of the Lie group SU(2). Nonconstant solutions of the Yang-Mills equations can be considered in the form of series of perturbation theory. The results of this paper are new and can be used to solve some problems in particle physics, in particular, to describe physical vacuum and to fully understand a quantum gauge theory.
