description: Workflow technology has been adopted in scientific domains to orchestrate and automate scientific processes in order to facilitate experimentation. Such scientific workflows often involve large data sets and intensive computation that necessitate the use of the Grid, which offers supercomputing power through shared distributed resources. To execute a scientific workflow in the Grid, tasks within the workflow that represent steps in the scientific process are assigned to Grid resources for execution. To ensure efficient execution of the workflow, Grid workflow scheduling is required to manage the allocation of Grid resources. Although many Grid workflow scheduling techniques exist, they are mainly designed for the execution of a single workflow. This is not the case with parameter sweep workflows which focus on parametric study and parameter optimisation. A parameter sweep workflow is executed numerous times with different input parameters in order to determine the effect of each parameter combination on the experiment. While executing multiple instances of a parameter sweep workflow in parallel can reduce the time required for the overall execution, this execution introduces new challenges to Grid workflow scheduling. Not only is a scheduling algorithm that is able to manage multiple workflow instances required, but this algorithm also needs the ability to schedule tasks across multiple workflow instances judiciously, as tasks may require the same set of Grid resources. Without appropriate resource allocation, resource competition problem could arise. In the thesis, we propose a new Grid workflow scheduling technique for parameter sweep workflow called the Besom scheduling algorithm. The scheduling decision of our algorithm is based on the resource dependencies of tasks in the workflow, as well as conventional Grid resource-performance metrics. In addition, the proposed technique is extended to handle loop structures in scientific workflows without using existing loop-unrolling techniques. We evaluate the Besom algorithm under a variety of conditions. A comparison between the simulation results of the Besom algorithm and of the three existing Grid workflow scheduling algorithms shows that the Besom algorithm is able to perform better than the existing algorithms for workflows that have complex structures and that involve overlapping resource dependencies of tasks. The Besom scheduling algorithm advances the ability to schedule parallel execution of parameter sweep workflows in the Grid. The outcomes of this thesis justify continuing research in this area to increase our understanding of scheduling multiple Grid workflow instances and to provide support to those involved in parametric study and scientific workflow management.

description: We construct the fcc (face centered cubic), bcc (body centered cubic) and sc (simple cubic) lattices as the root and the weight lattices of the affine Coxeter groups W(D3) and W(B3)=Aut(D3). The rank-3 Coxeter-Weyl groups describing the point tetrahedral symmetry and the octahedral symmetry of the cubic lattices have been constructed in terms of quaternions. Reflection planes of the Coxeter-Dynkin diagrams are identified with certain planes of the unit cube. It turns out that the pyritohedral symmetry takes a simpler form in terms of quaternionic representation. The D3 diagram is used to construct the vertices of polyhedra relevant to the cubic lattices and, in particular, constructions of the pseudoicosahedron and its dual pyritohedron are explicitly worked out.

description: Quantum aspects, such as electron tunneling between closely separated metallic nanoparticles, are crucial for understanding the plasmonic response of nanoscale systems. We explore quantum effects on the response of the conductively coupled metallic nanoparticle dimer. This is realized by stretching a nanorod, which leads to the formation of a narrowing atomic contact between the two nanorod ends. Based on first-principles time-dependent density-functional-theory calculations, we find a discontinuous evolution of the plasmonic response as the nanorod is stretched. This is especially pronounced for the intensity of the main charge-transfer plasmon mode. We show the correlation between the observed discontinuities and the discrete nature of the conduction channels supported by the formed atomic-sized junction.

Tweets (Microblogs)

description: This paper presents an empirical study of correlating Twitter sentiments with individual stock price movements. We used an existing text-mining technique, OpinionFinder, to extract Twitter sentiment data from plaintext tweets. Different from prior researches, we explored a novel approach to aggregate Twitter sentiment features and Twitter metadata features associated with the tweets that mention a technology stock to construct a set of features, which was then correlated with the stock price movements of the respective stock prices. We thereby selected a subset of these features, which have positive correlation coefficients with the stock prices, to predict future stock price movements. The results of the prediction, however, are not as successful as expected. Although it is too early to conclude that Twitter sentiments cannot be used to predict an individual stock price, our results do provide one piece of negative evidence for such hypothesis.

Can altruism lead to a willingness to take risks?

subject: Intensity of altruism

description: I study attitudes towards risk taking in cases where a person relates to others positively, namely altruistically. This study is needed because it is unclear how altruism influences the inclination of an altruistic person to take risks. Will this person’s risk-taking behavior differ if the utility of another person does not enter his utility function? Does being altruistic cause a person to become more reluctant to take risks because a risky undertaking turning sour will also damage his ability to make altruistic transfers? Or does altruism induce a person to resort to risky behavior because the reward for a successful outcome is amplified by the outcome facilitating a bigger transfer to the beneficiary of the altruistic act? Specifically, holding constant other variables, I ask: is an altruistic person more risk averse or less risk averse than a comparable person who is not altruistic? In response to this question, using a simple model in which preferences are represented by a logarithmic utility function, I show that an altruistic person who is an active donor (benefactor) is less risk averse than a comparable person who is not altruistic: altruism is a cause of greater willingness to take risks. The finding that the altruism trait causes greater willingness to take risks has not previously been noted in the existing literature.
The impact of mobile phones on the well-being of micro-entrepreneurs in Indonesia

Subjects: Uncategorized

description: Studies suggest that both mobile phones and micro-enterprises contribute significantly to social and economic development in developing countries. More recently, the discourse of development has changed. Development is no longer conceived of and measured by only in economic terms, but is also linked to social well-being, political structures, the physical environment, and human development (which is about giving people choices and enhancing individual ability to pursue preferred values). Research into use of Information and Communication Technologies (ICT) in developing countries needs to be re-adjusted to keep in step with the current approach where well-being (such as social relations within a community, gender, and the psychological and religious spheres) need to be considered. Current research on ICT for Development (ICTD) and particularly on mobile phones and micro-enterprises is lacking consideration of these spheres. This study focuses on understanding the impact of mobile technologies for human development in Indonesia. The central question that is addressed is whether, under what conditions, and how mobile phones can enhance the ability of individuals and communities to create and use opportunities to achieve the lifestyle which they value for themselves. Drawing on qualitative research design, this study investigates the use of mobile phones and their implications for micro-entrepreneurs’ well-being in Indonesia. Fieldwork was done in two cities in Indonesia, which are Makassar and Bandung. A grounded analysis is used to guide collection of data and to construct theory from the data. The findings from the interviews and observations led to an extensive exploration of business and personal usage of mobile phones, well-being perceptions of micro-entrepreneurs, defining elements of well-being, the dynamic proportion and inter-connections between elements, and the inter-relationships between mobile use and well-being perceptions. The findings are presented as models depicting the impact of mobile phones on micro-entrepreneurs’ well-being. The research explores the usefulness of the Capability Approach (CA) as a human development perspective.

Library instruction

description: The purpose of this study, conducted in Spring 2013, was to evaluate the effectiveness of the undergraduate library instruction program instituted as part of the first-year English 105 course at the University of North Carolina at Chapel Hill. ACRL's Information Literacy Competency Standards for Higher Education were used to develop learning outcomes to measure students' self-efficacy in an anonymous online survey. Also measured were students' emotional responses to doing research for a paper and level of procrastination. Results indicate that all student respondents felt at least moderately confident on eight tasks, but for four of the tasks, at least one student reported having no confidence. However, the role of the library instruction program in effecting these results is inconclusive. The lack of a pre-instruction survey, in combination with poor survey response, makes it impossible to generalize the results. Nevertheless, the results can provide a baseline of comparison for future research.

description: The gyromagnetic factor is an important physical quantity relating the magnetic-dipole moment of a particle to its spin. The electron spin g-factor in vacuo is one of the best model-based theoretical predictions ever made, showing agreement with the measured value up to ten parts per trillion. However, for electrons in a material the g-factor is modified with respect to its value in vacuo because of environment interactions. Here, we show how interaction effects lead to the spin g-factor correction in graphene by considering the full electromagnetic interaction in the framework of pseudo-QED. We compare our theoretical prediction with experiments performed on graphene deposited on SiO2 and SiC, and we find a very good agreement between them.

description: We study how rural households in Ethiopia adapt to droughts through labor reallocation. By using three waves of panel data and exploiting spatial-temporal variations in drought exposure, we find that households reduce on-farm work and increase off-farm self-employment in response to both short-term and persistent droughts, without abandoning family farming. Diversification into off-farm activities is driven by drought-related productivity declines in agriculture and contributes to consumption smoothing. Households with better access to markets and financial services find it easier to reallocate labor off-farm. Our results highlight the importance of strengthening the rural non-farm economy to enhance rural households’ climate resilience.

description: Despite the lack of a shear-rich tachocline region low-mass fully convective stars are capable of generating strong magnetic fields, indicating that a dynamo mechanism fundamentally different from the solar dynamo is at work in these objects. We present a self-consistent three dimensional model of magnetic field generation in low-mass fully convective stars. The model utilizes the anelastic magnetohydrodynamic equations to simulate compressible convection in a rotating sphere. A distributed dynamo working in the model spontaneously produces a dipole-dominated surface magnetic field of the observed strength. The interaction of this field with the turbulent convection in outer layers shreds it, producing small-scale fields that carry most of the magnetic flux. The Zeeman-Doppler-Imaging technique applied to synthetic spectropolarimetric data based on our model recovers most of the large-scale field. Our model simultaneously reproduces the morphology and magnitude of the large-scale field as well as the magnitude of the small-scale field observed on low-mass fully convective stars.

Subjects: Information management

description: This study describes a survey of nonprofit organizations to examine the use of donor information management tools and communication methods in relation to fundraising effectiveness. Sixty-four North Carolina based nonprofit organizations in the human services sector participated in the survey. The study tests the hypothesis that nonprofit organizations that utilize an information system to manage individual donor information are more effective in their fundraising efforts directed at individual donors than similar nonprofits that utilize less sophisticated tools to manage donor information. The results show some correlation, suggesting that nonprofits that utilize commercial database software to manage donor information are more effective in their fundraising efforts than those using less sophisticated tools such as manual lists and spreadsheets.

An autonomous incremental learning model for efficient mining of text data
Creators: name: Matharage, Sumith Shantha
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Proliferation of the World Wide Web has massively increased the availability of textual data in recent years, presenting a challenge for researchers to maximise the usage of this data with minimum human intervention. The field of text mining research has emerged as a solution to this, focusing on the development of new techniques to discover useful knowledge from these large volumes of text data. The main research challenges in the text mining field are; (a) unstructured nature of the text (b) capturing semantics information (c) coping with a large number of words and the structure of the natural language. There have been many different techniques proposed in the text mining literature trying to address the above mentioned challenges individually or as a combination. The Self Organizing Feature Map (SOM) algorithm is one of the most successful and widely used techniques among all these and has been extended for diverse text mining tasks. The primary aim of this thesis is to provide a more efficient autonomous incremental text clustering model. Also, improving the semantic aspects of the text clustering process is examined. A Fast Scalable Growing Self Organizing Map (FSGSOM) algorithm is proposed to provide a more efficient autonomous clustering of text based on the dynamic topology preservation capabilities of the Growing Self Organizing Map (GSOM) algorithm. To enrich the semantic capabilities, a dynamic variable length sequence based feature selection model is integrated into the feature selection phase. As an additional method of incorporating semantics, Wikipedia is used as a background information source in result interpretation. As most of the text information available is not stationary, an incremental learning model based on the FSGSOM clustering is proposed to handle non-stationary text information. The proposed model consists of a semi-continuous text processing model together with an evolving hierarchy of concepts to generalise and preserve the learning outcomes for future training. A template based document selection mechanism is utilised to form lateral connection across the different phases of learning. In summary, this thesis proposes a more efficient incremental text clustering and knowledge preservation model contributing to the field of text mining research.

The study  focuses primarily on the monetary incentive of FOSS given the unusual set of  circumstances in academia, including academic pricing and site licensing. The study  finds that listserv surveys are not an adequate way of doing research on the tech  community at UNC-Chapel Hill, especially in the arts, humanities and social science  departments. Study respondents also indicate there is little inter-departmental social  networking that occurs in survey responding. There is also strong incentive to use  proprietary software due to site licensing.

description: This paper examines how public libraries can best use social media as a marketing tool, specifically focusing on Facebook. Data was collected from 30 public library Facebook pages on number of posts, number of comments, and number of likes received during a two month period. This data was used to create a model that could fairly accurately predict how many likes a public library's Facebook page would receive based on several factors. Findings of this study suggest that a public library can effectively cultivate public interest through social media by posting to social media sites frequently, allowing for comments on social media sites, and posting about career achievements of current staff members.

description: Graphics, whether they are visually appealing elements or simply scribbles on a sheet of paper, are important tools used by people to convey information. They are widely used in educational and daily life materials such as newspapers, text books, web pages, electronic books, metro maps, instruction manuals etc. When appropriate they provide many cognitive benefits over text. Graphics are also becoming more sophisticated with recent advances in information visualisation applications, and now often include dynamic content such as animations and elements that can interact with the users. Unfortunately, graphics are not easily accessed by visually impaired people, in partic- ular by blind people. There have been many different approaches to solve this problem by using tactile, tactile-audio, haptic and speech/non-speech audio techniques, however, these approaches have limitations such as use of expensive tactile graphics or expensive peripheral devices, and they may not provide similar cognitive benefits to visual graphics. The main contribution of this thesis is GraVVITAS (Graphics Viewer using Vibra- tion, Interactive Touch, Audio and Speech) which addresses these limitations and presents graphics to blind people in a way which: (i) can be used effectively to read accessible versions of a wide range of graphics while preserving the cognitive benefits of visual graphics, (ii) is practical in terms of cost and portability, and (iii) provides an interactive display which allows dynamic exploration of graphics. A user- centered and participatory design methodology is used to develop GraVVITAS. A usability evaluation is then performed to investigate the interaction model of the final system. In addition to GraVVITAS the thesis has the following contributions: (i) an evaluation of assistive technologies used for presenting graphics to blind people by using theoretical analyses which assess the usability of these technologies, and to what extent they provide the cognitive benefits of graphics, (ii) a formal usability study which examines tactile and tactile-audio bar chart layouts for improving their effectiveness and readability, (iii) authoring tools developed to create accessible graphics.

description: This study of archival online user education resources is a content analysis of a sample of Association of Research Libraries. Features specifically examined are vocabulary and terminology definition, guidance in search strategies, and understanding primary source representation (the meanings and use of finding aids). This study also examines characteristics such as rules and regulations, the accessibility of these resources, and whether archival user education resources are made available directly on parent library websites. The findings indicate that while most institutions are offering some form of user education, certain elements of Yakel and Torres's concept of "archival knowledge" are not being widely offered in the online environment.

A framework for measuring the effectiveness of image representations
Creators: name: Le, Minh Viet
Publisher: name: Monash University

description: Image representations are abstract descriptions of images. They refer to ideas describing or modelling images, in a particular way, for further processing and analysis. For a given image application and a given image, there are various image representations that can be employed. It is desired that the best image representation is used. The best image representation minimises storage size while preserving maximum image information. The thesis proposes a framework to evaluate the effectiveness of image representations. The effectiveness of image representations is measured by their storage size and preserved image information, with respect to a given image application. In consequence, the proposed framework allows us to seek the best image representation for a given image. In the proposed framework, different image representations for a given image are realised by their corresponding image transformations. This step generates different sets of coefficients for different image representations. Next, methods for ordering coefficients in each set are employed to sort coefficients from most-to-least significant. This step allows us to obtain the best subset of coefficients in each representation, by selecting the most significant coefficients until the required storage is met. Then, an appropriate quality measure is applied to select the best subset of coefficients. The best subset of coefficients corresponds to the best image representation, for a given image. This thesis also proposes a quality measure for image representations. It is based on the perceptual quality evaluation of image representations. Experimental results have shown that the proposed quality measure correlates well with evaluation by the human visual system. Finally, a validation of the proposed framework is carried out. Following the proposed framework, a method to obtain the best wavelet representation is introduced. Given a set of wavelets to represent an image, the proposed method enables us to attain the best wavelet representation, in terms of the highest perceptual image quality for a given storage size. The best wavelet image representation can be used to gain better performance for image coding, image enhancement and image comparison applications.
Processing Numeric Table Data in Electronic Formats: Eye Movement Patterns and Searching Efficiency

description: This research describes an eye tracking study conducted at the Interaction Design Laboratory of the University of North Carolina at Chapel Hill. This experiment focused on identifying and analyzing user behavior and patterns when processing numeric table data in PDF and Table Browser formats. The Table Browser is an experimental tool for browsing statistical tables on the World Wide Web (WWW). Eleven sets of eye data were collected using the ASL 504 eye tracking system, and raw data were analyzed using EYENAL and FIXPLOT software.  Compared to the traditional PDF format, the Table Browser provided more choices for viewing and manipulating data. The table Browser was extremely useful, compared to the static PDF format, to deal with a difficult task in a large and complex table. For complex tasks such as comparing data or looking for trends, the Table Browser improves efficiency as measured by far less eye movement effort. For a simple task in a simple table, there is no obvious difference between these two formats.
Phenomenology of $P_c(4380)^+$, $P_c(4450)^+$ and related states

description: The $P_c(4380)^+$ and $P_c(4450)^+$ states recently discovered at LHCb have masses close to several relevant thresholds, which suggests they can be described in terms of meson-baryon degrees of freedom. This article explores the phenomenology of these states, and their possible partners, from this point of view. Competing models can be distinguished by the masses of the neutral partners which have yet to be observed, and the existence or otherwise of further partners with different isospin, spin, and parity. Future experimental studies in different decay channels can also discriminate among models, using selection rules and algebraic relations among decays. Among the several possible meson-baryon pairs which could be important, one implies that the states are mixtures of isospins 1/2 and 3/2, with characteristic signatures in production and decay. A previous experimental study of a Cabibbo-suppressed decay showed no evidence for the states, and further analysis is required to establish the significance of this non-observation. Several intriguing similarities suggest that $P_c(4450)^+$ is related to the $X(3872)$ meson.

An intelligent model based analysis of tobacco control policies
Creators: name: Ding, Xiaojiang
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: This thesis conducts an intelligent model based analysis to evaluate the effectiveness of tobacco control policies. By using the International Tobacco Control Four Country Survey data, the impact of tobacco control policies on smokers’ quitting behaviour is examined in four developed countries: Australia, Canada, the United Kingdom and the United States. A set of intelligent models are developed for predicting smokers’ quitting behaviour. The performance of these intelligent models is evaluated in order to select the best intelligent model for analyses. An attribute-based analysis is further conducted to investigate the underlying patterns and identify the factors that have the greatest impact on smokers’ plans to quit and their attempts to quit. Four policy drivers identified from the existing motivational attributes include: personal concerns, cigarette price, environmental restrictions and health system encouragement. They can be used to represent tobacco control policies. Outliers in the data are removed to improve the performance of the intelligent models. Results show that the derived policy drivers can fully represent the original attributes based on the performance of intelligent models using these two groups of input attributes. To evaluate the relative degrees of impact of tobacco control policies, hypothetical policy impacted populations are created to examine the variations of the quit attempt rate of smokers. Comparative studies are conducted for offering insightful analyses of impact degrees of tobacco control policies on different groups of smokers across the four countries. Results show that smokers’ health concerns and professional advice for quitting are two important factors to encourage quitting behaviour. Smoke-free policies may have a certain impact on increasing the quit attempt rate. In comparison with other tobacco control policies, the effectiveness of increasing cigarette price to reduce tobacco use is weak. Overall, this research establishes a methodological framework for modelling the complex planning process of tobacco control policies. In particular the framework can be used to measure the impact of specific tobacco control policies on smokers’ quitting behaviour across the four countries.
Electro-osmotic flow in coated nanocapillaries: a theoretical investigation

description: Motivated by recent experiments, we present a theoretical investigation of how the electro-osmotic flow occurring in a capillary is modified when its charged surfaces are coated by charged polymers. The theoretical treatment is based on a three dimensional model consisting of a ternary fluid-mixture, representing the solvent and two species for the ions, confined between two parallel charged plates decorated by a fixed array of scatterers representing the polymer coating. The electro-osmotic flow, generated by a constant electric field applied in a direction parallel to the plates, is studied numerically by means of Lattice Boltzmann simulations. In order to gain further understanding we performed a simple theoretical analysis by extending the Stokes-Smoluchowski equation to take into account the porosity induced by the polymers in the region adjacent the walls. We discuss the nature of the velocity profiles by focusing on the competing effects of the polymer charges and the frictional forces they exert. We show evidence of the flow reduction and of the flow inversion phenomenon when the polymer charge is opposite to the surface charge. By using the density of polymers and the surface charge as control variables, we propose a phase diagram that discriminates the direct and the reversed flow regimes and determine its dependence on the ionic concentration.

Subjects: Literacy

description: The United States has a literacy problem.  The National Center for Family Literacy estimates that over 34 million people struggle with basic literacy skills.  In order to determine the involvement of the Triangle Area (North Carolina) elementary public schools in family literacy programs, school literacy specialists were surveyed.  Unfortunately, there were insufficient responses to provide meaningful results.  A community assessment was then conducted that found the Augustine Project to be the best active program to help students struggling with literacy.  The amount of training that the Augustine Project provides far surpasses the America Reads Program, the other active program in the area.  During the 2008-2009 school year, the Augustine Project served 400 youth from 74 schools in four school districts within the Triangle Area while America Reads served 216 students.  Recommendations are offered that will lead to a better assessment of existing programs and how to address future needs.

description: We study the characterization of multipartite entanglement for the random states of an $n$-qbit system. Unable to solve the problem exactly we generalize it, changing complex numbers into real vectors with $N_c$ components (the original problem is recovered for $N_c=2$). Studying the leading diagrams in the large-$N_c$ approximation, we unearth the presence of a phase transition and, in an explicit example, show that the so-called entanglement frustration disappears in the large-$N_c$ limit.
