User’s Information Security Awareness in BYOD Programs: A Theoretical Model

We propose a new theoretical model to investigate the user’s information security awareness in bring-your-own-device (BYOD) programs. This model is built on the protection motivation theory and general deterrence theory. In addition, it has a discussion on the influence of a user’s cyber security inertia, a personal security management procrastination tendency, on the user’s security awareness of organization information resources. This model can provide a useful guideline for a BYOD security management.
ON NISTIR 8269 ( A TAXONOMY AND TERMINOLOGY OF ADVERSARIAL MACHINE LEARNING )

1. The academic adversarial machine learning literature focuses on the properties of different algorithms, rather than the diverse goals adversaries might have in attacking a system. We encourage adopting the language of security policies to explicitly tie adversarial actions to system vulnerabilities. This perspective presents a better framework for securing systems against a variety of adversarial threats.

Body Composition and Dietary Intake Patterns among Barbadian School Students: Relationships to Known and Postulated Dietary Fa

As a part of the Barbados Interdisciplinary Tropical Studies (BITS) program, and under the mentorship of Pamela Gaskin Ph.D. (University of the West Indies, Cave Hill Campus) and Stan Kubow, Ph.D. (McGill University), we undertook a 14-week-long pilot study and research project. The objective of this project was to assess body composition such as weight status and fat mass distribution and food intake patterns among 5 to 11year-old Barbadian students in both a rural and urban school. This information will be used to validate practical methods of data collection in children in a larger research study in Fall of 2009 that is aimed at describing the underlying factors related to nutritional and health concerns of the school aged population.
Wide Activation for Efficient Image and Video Super-Resolution

In this work we demonstrate that with same parameters and computational budgets, models with wider features before ReLU activation have signiﬁcantly better performance for image and video super-resolution. The resulted SR residual network has a slim identity mapping pathway with wider (2 × to 4 × ) channels before activation in each residual block. To further widen activation (6 × to 9 × ) without computational overhead, we introduce linear low-rank convolution into SR networks and achieve even better accuracy-efﬁciency tradeoffs. In addition, compared with batch normalization or no normalization, we ﬁnd training with weight normalization leads to better accuracy for deep super-resolution networks. Our proposed SR network WDSR achieves better results on large-scale DIV2K image super-resolution benchmark in terms of PSNR, under same or lower computational complexity. Based on WDSR, our method won 1st places in NTIRE 2018 Challenge on Single Image Super-Resolution in all three realistic tracks. Moreover, a simple frame-concatenation based WDSR achieved 2nd places in three out of four tracks of NTIRE 2019 Challenge for Video Super-Resolution and Deblurring . Our experiments and ablation studies support the importance of wide activation. Code and models will be publicly available.
Opinion Diversity Maximization in Social Networks

In recent years, the social networks play an important role as the information sources for many people. The algorithms applied by these platforms feed the users with opinions that meet their tastes. These algorithms, on the other hand, harm the free flow of information by forming filter bubbles and echo chambers. The motivation of the thesis is to break filter bubbles by maximizing the diversity of opinion exposures in a social network. To achieve the goal, we assume that we can change a limited number of users’ exposures to the information in the network. We propose two concrete models, bounded-box diversity maximization and the l2-bounded diversity maximization respectively. Both of them are convex maximization problems subject to different constraints. Besides the common cardinality constraint and linear constraint, the second model has an l2 constraint. We give a detailed exposition of convex maximization problems under different constraints. We prove that first problem can be discretized and transformed into the Quadratic Knapsack Problem (QKP), while the second one can not. Guided by convexity and QKP, Greedy Algorithms and Semidefinite Relaxation are applied. In a high level, the core idea of the Semidefinite Relaxation consist of two components: first, relaxing the original problem into Semidefinite Programming and obtaining a solution; second, rounding the solution to a feasible solution of the original problem through sampling from a Gaussian distribution. To evaluate our problem, we implement the algorithms on datasets that have clear chambers and low diversity structure. We show that semidefinite relaxation based algorithms work well when there are large changes on the cardinality, while when the changes are small, the greedy algorithms are comparable. The greedy algorithms have descent scalability for large datasets.
Thermal Instability of Chemically Reacting Maxwell Fluid in a Horizontal Porous Layer with Constant Heat Flux Lower Boundary

The effect of chemical reaction on the linear stability of a viscoelastic fluid saturated horizontal densely-packed porous layer is investigated. The viscoelastic properties are given by Maxwell constitutive relations. The porous layer is cooled from the upper boundary while an adiabatic thermal boundary condition is imposed at the lower boundary. Linear stability analysis suggests that there is a competition between the processes of viscous relaxation and thermal diffusion that causes the first convective instability to be oscillatory rather than stationary. The effect of Deborah number, Darcy-Prandtl number, normalized porosity, and the Frank-Kamenetskii number on the stability of the system is investigated. Using a weighted residual method we calculate numerically the convective thresholds for both stationary and oscillatory instability. The effects of viscoelasticity and chemical reaction on the instability are emphasized. Some existing results are reproduced as the particular cases of the present study.
Therapeutic evaluation of homeopathic treatment for canine oral papillomatosis

Aim: A study was conducted to evaluate the ameliorative potential of homeopathic drugs in combination (Sulfur 30C, Thuja 30C, Graphites 30C, and Psorinum 30C) in 16 dogs affected with oral papillomatosis which was not undergone any previous treatment. Materials and Methods: Dogs affected with oral papillomatosis, which have not undergone any initial treatment and fed with a regular diet. Dogs (total=16) were randomly divided into two groups, namely, homeopathic treatment group (n=8) and placebo control group (n=8). Random number table was used for allocation. Homeopathic combination of drugs and placebo drug (distilled water) was administered orally twice daily for 15 days. Clinical evaluation in both groups of dogs was performed by the same investigator throughout the period of study (12 months). Dogs were clinically scored for oral lesions on days 0, 5, 7, 10, 15, 20, 25, 30, 45, 60, 90, 120, and 150 after initiation of treatment. Results: The homeopathic treatment group showed early recovery with a significant reduction in oral lesions reflected by clinical score (p<0.001) in comparison to placebo-treated group. Oral papillomatous lesions regressed in the homeopathic group between 7 and 15 days, whereas regression of papilloma in the placebo group occurred between 90 and 150 days. The homeopathic treated group was observed for 12 months post-treatment period and no recurrence of oral papilloma was observed. Conclusion: The current study proves that the combination of homeopathy drugs aids in fastening the regression of canine oral papilloma and proved to be safe and cost-effective.
In Situ Investigation of Dynamic Silver Crystallization Driven by Chemical Reaction and Diffusion

Rational synthesis of materials is a long-term challenging issue due to the poor understanding on the formation mechanism of material structure and the limited capability in controlling nanoscale crystallization. The emergent in situ electron microscope provides an insight to this issue. By employing an in situ scanning electron microscope, silver crystallization is investigated in real time, in which a reversible crystallization is observed. To disclose this reversible crystallization, the radicals generated by the irradiation of electron beam are calculated. It is found that the concentrations of radicals are spatiotemporally variable in the liquid cell due to the diffusion and reaction of radicals. The fluctuation of the reductive hydrated electrons and the oxidative hydroxyl radicals in the cell leads to the alternative dominance of the reduction and oxidation reactions. The reduction leads to the growth of silver crystals while the oxidation leads to their dissolution, which results in the reversible silver crystallization. A regulation of radical distribution by electron dose rates leads to the formation of diverse silver structures, confirming the dominant role of local chemical concentration in the structure evolution of materials.
Using Co-Visitation Networks For Classifying Non-Intentional Traffic

Data generated by observing the actions of web browsers across the internet is being used at an ever increasing rate for both building models and making decisions. In fact, a quarter of the industry-track papers for KDD in 2012 were based on data generated by online actions. The models, analytics and decisions they inform all stem from the assumption that observed data captures the intent of users. However, a large portion of these observed actions are not intentional, and are effectively polluting the models. Much of this observed activity is either generated by robots traversing the internet or the result of unintended actions of real users. These nonintentional actions observed in the web logs severely bias both analytics and the models created from the data. In this paper, we will show examples of how non-intentional traffic adversely affects both general analytics and predictive models, and propose an approach using co-visitation networks to identify sites that have large amounts of non-intentional traffic. We will then show how this approach, along with a second stage classifier that identifies non-intentional traffic at the browser level, is deployed in production at Media6Degrees (m6d), a targeting technology company for display advertising. This deployed product acts to both filter out the spurious traffic from the input data and to insure that we don’t serve ads during unintended website visits.

A Study of the Correlations Between Consumption Experience, Customer Satisfaction, Brand Image and Behavior Intention of Motels in Taiwan

In recent years there has been a trend for motels in Taiwan to introduce innovative concepts and daring ideas in an attempt to outdo one another. Based on the case study of motels, this research explores correlations between experiential marketing, experiential value, customer satisfaction, brand image and behavior intention. The empirical analysis is done through LISREL in order to provide operational references for motel administrators and to help them enhance product competitiveness. Empirical analysis reveals through different experiential values that experiential marketing is positively correlated with customer satisfaction. Therefore, changes in pricing or product strategies is recommended. Motel managers may want to establish interesting amenities within the premises in order to offer motel guests additional entertainment.
Structure, Conduct, and Contact: Competition in Closely-Related Markets∗

We perform a simultaneous empirical study of demand and competition patterns in 40 product categories of the Israeli food sector. In each category we estimate a differentiated product demand model, and use the estimates to compute indicators that capture the category’s potential of sustaining equilibria with prices that are above the competitive levels. These indicators are threshold discount factors: the smallest ones required for supporting such hypothetical equilibria, whether or not they are actually played in practice. We then investigate how those thresholds vary with within-category concentration levels, and also how they respond to cross-category interactions (multimarket contact). We also study the relationship between a category’s concentration and its demand elasticity. By combining these analyses we provide a multi-faceted picture of competition and concentration in closely related markets. ∗The analysis in this paper is based on Nielsen data and is entirely that of the authors and not of Nielsen.

Investigation of Mechanical Properties of Polyester, Acrylic, Polyamide Fiber Reinforced Epoxy Composites

Composite materials are materials obtained by combining materials with two or more different properties that are used by people for thousands of years to solve problems without being aware of them. Polymer based composite materials have recently been developed to improve the properties of these materials, as they have many superior properties as well as insufficient strength. Depending on technological developments, different types of composites have been produced using different types of matrix and reinforcement. The purpose of this study is to produce and examine mechanical properties of polyester, acrylic and polyamide fiber reinforced epoxy composites. The composites were produced by the method of hand lay-up. Tensile, impact, flexural and interlaminar shear strength (ILSS) tests were performed on the prepared specimens. Increases in the fibre content had various effects on the above mentioned mechanical properties of the obtained composites.
The Dynamics of Team Cognition:

Team cognition has been identified as a critical component of team performance and decision-making. However, theory and research in this domain continues to remain largely static; articulation and examination of the dynamic processes through which collectively held knowledge emerges from the individualto the team-level is lacking. To address this gap, we advance and systematically evaluate a process-oriented theory of team knowledge emergence. First, we summarize the core concepts and dynamic mechanisms that underlie team knowledge-building and represent our theory of team knowledge emergence (Step 1). We then translate this narrative theory into a formal computational model that provides an explicit specification of how these core concepts and mechanisms interact to produce emergent team knowledge (Step 2). The computational model is next instantiated into an agent-based simulation to explore how the key generative process mechanisms described in our theory contribute to improved knowledge emergence in teams (Step 3). Results from the simulations demonstrate that agent teams generate collectively shared knowledge more effectively when members are capable of processing information more efficiently and when teams follow communication strategies that promote equal rates of information sharing across members. Lastly, we conduct an empirical experiment with real teams participating in a collective knowledge-building task to verify that promoting these processes in human teams also leads to improved team knowledge emergence (Step 4). Discussion focuses on implications of the theory for examining team cognition processes and dynamics as well as directions for future research.
Taint analysis for automotivesafety using the LLVM compilerinfrastructure Éléonore Goblé

Software safety is getting more and more important in the automotive industry as mechanical functions are replaced by complex embedded computer systems. Errors during development can lead to accidents and threaten users’ lives. The safety level of the software must therefore be monitored through Automotive Safety Integrity Levels (ASILs), according to the standard ISO 26262. This thesis presents the development of a static taint analysis tool using the LLVM compiler infrastructure in order to identify safety-critical components and analyze their dependencies in automotive software. The aim was to provide a useful visualization tool to help safety engineers in their work and save time during development. It was concluded that this static taint analysis tool can facilitate and improve the precision of the ASIL decomposition of automotive software.
The relationship between accounting conservatism and efficiency of investment decisions in light of managerial ownership: The case of the tourism industry in Jordan

The study aimed to examine the relationship between accounting conservatism and investment efficiency decision in light of difference managerial equity as the specified basis of the investment decisions efficiency. The study model was designed based on the consideration that accounting conservatism represents the independent variable, while the investment decisions efficiency represents the dependent variable. The research measured the independent variable to sample study by using a scale of Rasu (1997), While the research used the Biddle et. al., (2009) model to measure the dependent variable. To achieve the objective of the study, we tested a hypothesis by using the designed model but with different levels of its managerial ownership in a sample of 87 Jordanian tourism companies for the period 20132017. The results of the study supported its hypothesis as it showed the existence of different relations between accounting conservatism and investment efficiency decisions according to the difference in the ratio of the managerial ownership. We have found that the majority of the Jordanian companies do not follow conservative accounting policies, so the phenomenon of asymmetry of information and inefficiency of investment decision prevails. We have also found that in conservative companies, the efficiency of investment decisions depends on the level of marginal conservatism, which differs from one level to another. The current study makes an essential contribution through empirically displaying that managerial ownership has an impact on the relationship between accounting conservatism and investment decisions efficiency, moreover, the result of the study refuted the view that the benefit of the accounting conservative approach is absolute in improving the quality of financial reports and increases the efficiency of investment decisions and also reduces the agency problems by revealing the existence of what the researchers called the marginal level of benefit of a conservative approach. This is because the conservatism was linked to a manager's motives.
