Enhancing Sustainability of Tomato, Pepper and Melon Nursery Production Systems by Using Compost Tea Spray Applications
Year: 2020

Compost teas (CTs) are liquid organic formulates obtained by prolonged extraction, with or without aeration, of a quality compost into an aqueous medium. They can significantly improve plant growth and development likely through nutritive and/or biostimulant mechanisms. In nursery production chain of tomato, pepper and melon, the use of seven CTs was evaluated in order to substitute, totally or partially, chemical treatments with propamocarb hydrochloride (47.3% and fosetyl Al (27.7% a fungicide for the pathogenic oomycetes control. In general, CTs increased plant growth parameters, as suggested by measurements of root length +9.1% and +8.1% on average, on tomato and pepper, respectively) stem diameter +12% on average, on tomato) number of leaves +2.6% on average, on melon) and fresh biomass +8.2% on average, on melon) in comparison with the chemical control. CT from artichoke and fennel composted residues have had the major impact on nursery performances of tomato, pepper and melon. After the first treatment of the polystyrene trays with the fungicide at sowing, our results indicated that CT may replace it in the following seedling production cycle, securing vegetative characteristics of nursery plants similar to the chemical control, that may incite fast starting of transplants in the field stage.
Using templates to elicit implied security requirements from functional requirements a controlled experiment
Venue: ESEM '14
Year: 2014

Security requirements for software systems can be challenging to identify and are often overlooked during the requirements engineering process. Existing functional requirements of a system can imply the need for security requirements. Systems having similar security objectives (e.g. confidentiality) often also share security requirements that can be captured in the form of reusable templates and instantiated in the context of a system to specify security requirements.  We seek to improve the security requirements elicitation process by automatically suggesting appropriate security requirement templates implied by existing functional requirements.  We conducted a controlled experiment involving 50 graduate students enrolled in a software security course to evaluate the use of automatically suggested templates in eliciting implied security requirements. Participants were divided into treatment (automatically suggested templates) and control groups (no templates provided)  Participants using our templates identified 42% of all the implied security requirements in the oracle as compared to the control group, which identified only 16% of the implied security requirements. Template usage increased the efficiency of security requirements identified per unit of time.  Automatically suggested templates helped participants (security non experts) think about security implications for the software system and consider more security requirements than they would have otherwise. We found that participants need more incentive than just a participatory grade when completing the task. Further, we recommend to ensure task completeness, participants either need a step driven (i.e. wizard) approach or progress indicators to identify remaining work.
Genetically Modified Crops, Inclusion, and Democracy
Venue: Perspectives on Science
Year: 2017

The public controversy over genetically modified (GM) crops is predominantly framed in terms of health and safety risks to humans and the environment. However, opponents of GM crops are motivated by a wide variety of other social, political, and economic concerns. In this paper, I critically assess the predominance of the health and safety framing in terms of Iris Young's model of communicative democracy. I argue that the health and safety framing leads to the marginalization of the social, political, and economic concerns of GM opponents, within both public discourse and government, and is therefore democratically illegitimate.
The Iterative Convergent Design for Mobile Health Usability Testing: Mixed Methods Approach
Venue: JMIR mHealth and uHealth
Year: 2019

Although patients express an interest in using mobile health (mHealth) interventions to manage their health and chronic conditions, many current mHealth interventions are difficult to use. Usability testing is critical for the success of novel mHealth interventions. Researchers recognize the utility of using qualitative and quantitative approaches for usability testing, but many mHealth researchers lack the awareness of integration approaches from advances in mixed methods research that can add value to mHealth technology. As efficient usability testing proceeds iteratively, we introduce a novel mixed methods design developed specifically for mHealth researchers. The iterative convergent mixed methods design involves simultaneous qualitative and quantitative data collection and analysis that continues cyclically through multiple rounds of mixed methods data collection and analysis until the mHealth technology under evaluation is found to work to the satisfaction of the researcher. In cyclical iterations, early development is more qualitatively driven but progressively becomes more quantitatively driven. Using this design, mHealth researchers can leverage mixed methods integration procedures in the research question, data collection, data analysis, interpretation, and dissemination dimensions. This study demonstrates how the iterative convergent mixed methods design provides a novel framework for generating unique insights into multifaceted phenomena impacting mHealth usability. Understanding these practices can help developers and researchers leverage the strengths of an integrated mixed methods design.
International on line reciprocal peer tutoring to promote modern language development in primary schools
Venue: Comput. Educ.
Year: 2009

The paper reports data from an on line peer tutoring project. In the project 78, 9 12 year old students from Scotland and Catalonia peer tutored each other in English and Spanish via a managed on line environment. Significant gains in first language (Catalonian pupils) modern language (Scottish pupils) and attitudes towards modern languages (both Catalonian and Scottish pupils) were reported for the experimental group as compared to the control group. Results indicated that pupils tutored each other in using Piagetian techniques of error correction during the project. Error correction provided by tutors to tutees focussed on morph syntaxys, more specifically the correction of verbs. Peer support provided via the on line environment was predominantly based on the tutor giving the right answer to the tutee. High rates of impact on tutee corrected messages were observed. The implications for peer tutoring initiative taking place via on line environments are discussed. Implications for policy and practice are explored.
Targeted poverty alleviation and land policy innovation: Some practice and policy implications from China
Year: 2018

Poverty is the common challenge faced by the international community. The human society has never ceased to struggle against poverty. China was once the developing country with the largest rural poor population in the world. Facing the decreasing effect of economic input to poverty reduction, land policy innovations could contribute to promoting poverty alleviation, particularly in China, where the defects in policy making is regarded as a major factor in rural poverty. This study explores the institutional innovation of China's poverty alleviation since 2013 and further reveals the mechanism behind land policy innovation promoting the targeted poverty alleviation based on a case study of Songjiagou village of Fuping county, Hebei province. We found that the Chinese central government has innovated the mechanism for the TPA to lift the remaining rural poor out of poverty by 2020 as scheduled. Implementing the TPA could confront the labor, capital and land dilemmas. Combined land policy innovations and land engineering with the ex situ poverty alleviation relocation (ESPAR) can help to break the institutional barriers. We argue that land policy innovations and the ESPAR not only contributes to poverty reduction and improve living conditions of the poor, but also needs to guard against its potential risk. These findings can provide policymakers with a sound scientific basis for poverty reduction planning and decisions in China and other poor countries.
Structure function relationship of artificial spider silk fibers produced by straining flow spinning.
Venue: Biomacromolecules
Year: 2020

Production of large quantities of artificial spider silk fibers that match the mechanical properties of the native material has turned out to be challenging. Recent advancements in the field make biomimetic spinning approaches an attractive way forward since they allow the spider silk proteins to assemble into the secondary, tertiary and quaternary structures that are characteristic of the native silk fiber. Straining flow spinning (SFS) is a newly developed and versatile method that allows production under a wide range of processing conditions. Here, we use a recombinant spider silk protein that shows unprecedented water solubility and that is capable of native like assembly, and spin it into fibers by the SFS technique. We show that fibers may be spun using different hydrodynamical and chemical conditions and conclude that these spinning conditions affect fiber mechanics. In particular, it was found that the addition of acetonitrile and polyethylene glycol to the collection bath results in fibers with increased b sheet content and improved mechanical properties.
Existence and uniqueness theorems for solutions of McKean Vlasov stochastic equations
Year: 2016

New weak and strong existence and weak and strong uniqueness results for multi dimensional stochastic McKean Vlasov equations are established under relaxed regularity conditions. Weak existence is a variation of Krylov's weak existence for Ito's SDEs under the nondegeneracy of diffusion and no more than a linear growth in the state variable; this part is designed to fill in the existing gap, as earlier such results for McKean Vlasov equations were not written. Weak and strong uniqueness is established under the restricted assumption of diffusion depending only on time and the state variable, yet without any regularity of the drift in the state variable and also under a linear growth condition on the drift; this part is based on the analysis of the total variation metric.
Vision Based Hand Gesture Recognition for Human Computer Interaction
Year: 2018

The hand gesture recognition system is widely used in the development of human machine interaction. The vision based hand gesture recognition is achieved by the following steps: preprocessing, feature extraction and classification. The aim of preprocessing stage is to localize the hand region from the image frame. The Laplacian of Gaussian filtering technique along with zero crossing detector is applied on hand gesture images to detect the edges of hand region. This work proposes a novel feature extraction technique, which is based on local histogram feature descriptor (LHFD) The proposed feature is extracted by finding the local histogram of the grayscale gesture image. This technique uses the whole region of the hand to extract the features. The proposed method is invariant to the scaling and illumination. Two standard datasets viz. Massey University gesture dataset (MUGD) and Jochen Triesch static hand posture database are used to evaluate the recognition performance of the proposed technique. The gesture recognition performance of the proposed technique is 99.5%and 95%on Massey University gesture dataset and Triesch dataset respectively, using support vector machine (SVM) classifier. Fourier descriptor along with Convolutional neural network is proposed for continuous frame based hand gesture recognition. Fourier descriptor is used to construct the smooth boundary of each frame of video. CNN is used for classification, the recognition accuracy of the proposed method for dynamic hand gesture recognition is of77:5%
Smoke and heat emissions from boundaries of fire compartments and the impact of installation methods
Year: 2015

A B S T R A C T Fire resistance testing is intended to provide criteria and verification methods for stopping of fire spread between fire compartments. It has been used with success for this purpose for decades. The principle, testing schemes, and criteria do not provide information about tenability conditions in adjacent fire compartments however. This drawback has become increasingly obvious as fire safety engineering started to make it possible to evaluate tenability conditions using data on smoke emissions from construction materials and products, and as construction products with potency to emit significant amounts of opaque and toxic effluents found the way to building systems including those providing fire resistance. Findings of fire resistance testing of six non loadbearing walls made of commonly used composite metal faced sandwich panels, two filled with mineral stone wool as core insulation (MW) and four filled with polymer polyisocyanurate (PIR) insulation material, demonstrated these effects. The project has been recently expanded by additional measurements of gas and particle effluents. This paper deals with new information reflecting back on original test results.
Airplane pilot flight performance on 21 maneuvers in a flight simulator under varying carbon dioxide concentrations
Venue: Journal of Exposure Science Environmental Epidemiology
Year: 2018

BackgroundRecent studies suggest that carbon dioxide has an impact on cognitive function performance of office workers at concentrations previously thought to be benign (1000 2500 ppm) The only available data for CO2 on the flight deck indicate that the average CO2 concentrations are typically <1000 ppm, but the 95th percentile concentration can be as high as 1400 ppm, depending on airplane type.MethodsWe recruited 30 active commercial airline pilots to fly three 3 h flight segments in an FAA approved flight simulator with each segment at a different CO2 concentration on the flight deck (700, 1500, 2500 ppm) CO2 concentrations were modified by introducing ultra pure CO2 into the simulator; ventilation rates remained the same for each segment. The pilots performed a range of predefined maneuvers of varying difficulty without the aid of autopilot, and were assessed by a FAA Designated Pilot Examiner according to FAA Practical Test Standards. Pilots and the Examiner were blinded to test conditions and the order of exposures was randomized.ResultsCompared to segments at a CO2 concentration of 2500 ppm, the odds of passing a maneuver as rated by the Examiner in the simulator were 1.52 (95% CI: 1.02 2.25) times higher when pilots were exposed to 1500 ppm and 1.69 (95% CI: 1.11 2.55) times higher when exposed to 700 ppm, controlling for maneuver difficulty, Examiner and order of maneuvers.DiscussionExaminer rating captured a wider range of performance indicators than output from the flight simulator, which can characterize only a few quantitative aspects of the flight performance. More broadly, these findings suggest that there is a direct effect of carbon dioxide on performance, independent of ventilation, with implications for many other indoor environments that routinely experience CO2 concentrations above 1000 ppm.
Forensic Accounting, Tax Fraud and Tax Evasion in Nigeria Review of Literatures and Matter for Policy Consideration
Year: 2020

Tax Fraud (TF) and Tax Evasion (TE) has become an alarming situation in most developing countries. It has become a focus of attention in recent times by scholars and policy makers because of its impact on the economy. In Nigeria, the recent worldwide economy downturn through COVID 19 pandemic and decrease in price of crude oil and sales quantity in the global market has contributed to difficulties in the implementation of annual budget. This called for a shift to tax revenues (TR) but the major challenge is the high rate of TF and TE. One way of reducing this menace and to instil Tax Compliance (TC) is the application of Forensic Accounting (FA) techniques. Therefore, this call for better understanding of the concepts and ways of using FA to promote TC. It is against this background that the study examined FA, TF and TE in Nigeria. The study adopts exploratory research design with literatures from materials on taxation and accounting. The study concluded that since the traditional auditing techniques has failed to curb TF and TE because of its inefficiency and ineffectiveness of operation, therefore FA will expose, control and deter fraudulent practices on TR, and this will enhance good TR for the government. The study recommends that government should develop interest in FA, enforce tax laws and regulations on TF and TE with strict appropriate punishment on tax evaders, ensure transparency and accountability on TR, and further create forensic unit in tax offices with modern FA techniques equipment.

Venue: 2013 27th International Conference on Advanced Information Networking and Applications Workshops
Year: 2013

Internet of Things (IoT) enables a homogeneous and seamless machine to machine (M2M) between any Internet enabled devices in the real world. IoT provides global communications, access to services and information for the development of Smart Cities, environmental monitoring, bus tracking and parking. For this purpose, IoT requires scalability, extensibility, and integration of emerging resources in order to reach a suitable ecosystem for data acquisition and interaction with the citizens. This work presents a way to interact with the IoT through a homogeneous and suitable mechanism for the global resource discovery of devices and sensors on different scenarios. For discovery purpose, a infrastructure called "digcovery" is defined for maximizing efficiency and sustainability of deployments offering the framework to allow users to register/include their own sensors into a common infrastructure, and access/discover the available resources through a mobile phone. This presents how to use the smartphone capabilities, in terms of identification, geo location and context awareness, to access and interact with the available resources that are surrounding us.

Graph Adaptive Knowledge Transfer for Unsupervised Domain Adaptation
Venue: ECCV
Year: 2018

Unsupervised domain adaptation has caught appealing attentions as it facilitates the unlabeled target learning by borrowing existing well established source domain knowledge. Recent practice on domain adaptation manages to extract effective features by incorporating the pseudo labels for the target domain to better solve cross domain distribution divergences. However, existing approaches separate target label optimization and domain invariant feature learning as different steps. To address that issue, we develop a novel Graph Adaptive Knowledge Transfer (GAKT) model to jointly optimize target labels and domain free features in a unified framework. Specifically, semi supervised knowledge adaptation and label propagation on target data are coupled to benefit each other, and hence the marginal and conditional disparities across different domains will be better alleviated. Experimental evaluation on two cross domain visual datasets demonstrates the effectiveness of our designed approach on facilitating the unlabeled target task learning, compared to the state of the art domain adaptation approaches.
The CBL CIPK network in plant calcium signaling.
Venue: Trends in plant science
Year: 2009

Calcium (Ca2+ is a ubiquitous second messenger in all eukaryotes. An outstanding question is how this cation serves as a messenger for numerous signals and confers specific cellular responses. Recent studies have established a concept termed 'Ca2+ signature' that specifies Ca2+ changes triggered by each signal. How do cells recognize these signatures (codes) and translate them into the correct cellular responses? The initial step in this 'decoding' process involves sensor proteins that bind Ca2+ and activate the downstream targets, thereby regulating the specific biochemical processes. Here, I review and discuss a set of Ca2+ sensors (calcineurin B like proteins [CBLs] and their targets (CBL interacting protein kinases [CIPKs] as an emerging paradigm for Ca2+ decoding in plants. The principles governing the action of the CBL CIPK signaling network could be generally applicable to many other signaling networks in plants and other organisms.
