Francisella tularensis is a Gram-negative bacterium that can cause tularemia in humans. The disease can be acquired through several routes, one of which is the ingestion of contaminated food and water. The pathogen has the potential to be used as a biological weapon, and its intentional introduction in the food supply is a possible way to cause public harm. The purpose of this study was to evaluate the growth and/or survival of F. tularensis in food matrices under various storage conditions. Cystine Heart Agar enriched with 2% hemoglobin and supplemented with antibiotics was used to aid the enumeration of the target organism by suppressing the levels of indigenous microflora in foods. During the first portion of the study, the growth/survival of highly virulent F. tularensis subsp. tularensis SCHU S4 strain was investigated in prepared bagged iceberg lettuce stored at two temperatures. F. tularensis counts were significantly different (p≤0.05) among temperature levels for days 1-3, but not day 4. After the first 24 h of incubation, the mean estimates of F. tularensis counts were 1.00 log cfu g⁻¹ lower in lettuce stored at 23±1°C compared to lettuce stored at 6±1°C. Lower recovery rates at higher temperatures are likely due to the more rapid proliferation of naturally present bacteria which can inhibit the growth of F. tularensis. After 48 and 72 h, differences in F. tularensis counts between temperatures were 0.55 log cfu g⁻¹ and 0.3 log cfu g⁻¹, respectively. For the second portion of the experiment, the ability of F. tularensis to grow or survive was evaluated in nine food matrices with variable compositional content (red delicious apples, green bell pepper, shredded iceberg lettuce, strawberries, whole liquid eggs, boneless ham steak, beef hot dogs, 80-20 ground beef, and 2% UHT milk) at 4, 21, and 37°C. F. tularensis grew well in pasteurized whole liquid eggs stored at 21 and 37°C. With the exception of ham, liquid whole eggs, and bell pepper, the pathogen was detected infrequently throughout the duration of the study. Very low recovery rates were obtained for shredded lettuce, hot dogs, and ground beef.

Full textAbstract:
The purpose of the thesis is to present a foundation for selecting an appropriate model while building a concurrent network server, focusing on a comparison between a select() based server and one thread for each connection. The test conducted herein is based two echo servers ( the message sent is echoed back to the sender ) and the time they take to serve a number of clients. The programs written for it are run on both Windows and Linux to show if the choice of platform affects the methods efficiency. Also looking at the return time of select() when we have a number of sockets, as well the time it takes to create a set number of threads. The conclusion drawn in this thesis is that for up to 512 sockets there is really no significant difference in the time it takes for the test program to return, this was true for both the Windows and the Linux test. Note however that the threading implementation requires much more memory than the select based one. So in the end it is basically up to personal preferences.E-Mail: Nicklas.Franzen@gmail.com Mobile: 0703-506904

Russell, William Edward. "Managing innovation search and select in disrupting environments." Thesis, University of Exeter, 2016. http://hdl.handle.net/10871/21870.
Full textAbstract:
This thesis explores how organisations manage new product development (NPD) focused innovation across a portfolio of core, adjacent and breakthrough environments. The study focuses on the search and select phases of the innovation process, and how incumbents identify and validate a range of opportunities. Organisations face the paradox of how to establish search and select routines for focal markets, while also setting up routines to sense and respond to disruptive innovation signals from adjacent and more peripheral environments. The study builds on research into peripheral vision, and considers how organisations operationalise innovation search and select in disrupting environments. To analyse how organisations manage search and select in turbulent environments, the author conducted research in the disrupting higher education (HE) publishing industry using qualitative research methods. The study focused on ten case companies, and the researcher conducted 61 interviews with 63 individuals over a six month period across ten companies publishing 9,000 out of the world’s 32,000 academic journals. The interviewees ranged from CEOs and CTOs to production, operations, editorial, publishing, sales and marketing directors and managers. The analysis revealed 11 search and select capabilities that need to be in place to manage NPD effectively in HE publishing. The research identified five contextual factors that influence how search and select is operationalised in disrupting environments. A framework is proposed to enable the mapping of individual opportunities within a wider NPD portfolio. The project identified ten key market insight areas where firms in the HE publishing sector need to focus. The findings have implications for practice, especially for HE publishers, online media companies, and business to business service organisations. Further research is proposed into how the cognitive frames of boards and senior teams affect the structure and operationalisation of NPD portfolios; how visual media companies search for, develop (ideate) and select programme and film projects in the disrupting media sector; and how workflow mapping and the identification of jobs-to-be-done is deployed within the NPD process in different settings.

Full textAbstract:
For a long time logistics have been an important part of industrial activities. Dated from 1970s, with the emergency of third party logistics (TPL), companies began to think about insourcing or outsourcing. As the development and expansion of TPL, outsourcing logistics activities to third party logistic have became a worldwide trend. Companies could gain a competitive advantage from outsourcing. Outsourcing to TPL providers could make companies focus on their core tasks. An appropriate TPL provider could apply technology and expertise, which help companies reducing costs and improving services. Flexibility and efficiency can also be achieved by adopting good TPL providers. In this sense, helping companies to make outsourcing decisions and to select optimal TPL providers is meaningful. The purpose of this thesis is to bring a holistic view of third party logistics and to build models for companies to select optimal TPL providers. To achieve the purpose, relevant literatures were reviewed to gain theoretical bases. Qualitative and quantitative research methods are both used in the thesis. Two models for selecting TPL providers were built in the thesis. One was qualitative model that contained four steps: defining problems, formulate criteria, qualify selection process and finally make decision. The other one was a quantitative model with DEA method. It contained six steps: define problem, select candidates, select criteria and indicators, determine input and output and collect data, calculate the efficiency and make final decision. Each model was applied on a case study to examine its validity and feasibility. Both advantages and disadvantages were found during the case studies. The conclusion is that both of models could be used for companies and it allows a company to choose the most suitable one.

Peng, Jie. "Learning to select for information retrieval." Thesis, University of Glasgow, 2010. http://theses.gla.ac.uk/1897/.
Full textAbstract:
The effective ranking of documents in search engines is based on various document features, such as the frequency of the query terms in each document, the length, or the authoritativeness of each document. In order to obtain a better retrieval performance, instead of using a single or a few features, there is a growing trend to create a ranking function by applying a learning to rank technique on a large set of features. Learning to rank techniques aim to generate an effective document ranking function by combining a large number of document features. Different ranking functions can be generated by using different learning to rank techniques or on different document feature sets. While the generated ranking function may be uniformly applied to all queries, several studies have shown that different ranking functions favour different queries, and that the retrieval performance can be significantly enhanced if an appropriate ranking function is selected for each individual query. This thesis proposes Learning to Select (LTS), a novel framework that selectively applies an appropriate ranking function on a per-query basis, regardless of the given query's type and the number of candidate ranking functions. In the learning to select framework, the effectiveness of a ranking function for an unseen query is estimated from the available neighbouring training queries. The proposed framework employs a classification technique (e.g. k-nearest neighbour) to identify neighbouring training queries for an unseen query by using a query feature. In particular, a divergence measure (e.g. Jensen-Shannon), which determines the extent to which a document ranking function alters the scores of an initial ranking of documents for a given query, is proposed for use as a query feature. The ranking function which performs the best on the identified training query set is then chosen for the unseen query. The proposed framework is thoroughly evaluated on two different TREC retrieval tasks (namely, Web search and adhoc search tasks) and on two large standard LETOR feature sets, which contain as many as 64 document features, deriving conclusions concerning the key components of LTS, namely the query feature and the identification of neighbouring queries components. Two different types of experiments are conducted. The first one is to select an appropriate ranking function from a number of candidate ranking functions. The second one is to select multiple appropriate document features from a number of candidate document features, for building a ranking function. Experimental results show that our proposed LTS framework is effective in both selecting an appropriate ranking function and selecting multiple appropriate document features, on a per-query basis. In addition, the retrieval performance is further enhanced when increasing the number of candidates, suggesting the robustness of the learning to select framework. This thesis also demonstrates how the LTS framework can be deployed to other search applications. These applications include the selective integration of a query independent feature into a document weighting scheme (e.g. BM25), the selective estimation of the relative importance of different query aspects in a search diversification task (the goal of the task is to retrieve a ranked list of documents that provides a maximum coverage for a given query, while avoiding excessive redundancy), and the selective application of an appropriate resource for expanding and enriching a given query for document search within an enterprise. The effectiveness of the LTS framework is observed across these search applications, and on different collections, including a large scale Web collection that contains over 50 million documents. This suggests the generality of the proposed learning to select framework. The main contributions of this thesis are the introduction of the LTS framework and the proposed use of divergence measures as query features for identifying similar queries. In addition, this thesis draws insights from a large set of experiments, involving four different standard collections, four different search tasks and large document feature sets. This illustrates the effectiveness, robustness and generality of the LTS framework in tackling various retrieval applications.

Full textAbstract:
EMBA Project ReportEXECUTIVE SUMMARY: The Navy and Marine Corps Rotary-wing community is experiencing unprecedented expansion while becoming more technically complex than ever before. As a result, the quality of pilots required by each Rotary-wing community has increased as well. Currently, the only pipelines that require a minimum Navy Standard Score (NSS) for selection are: USMC Jet (52); Navy Tailhook (50); and USMC Tilt-rotor (40). The remaining pipelines, E6 (Navy only), Multiengine, and Rotary-wing do not require a minimum NSS for selection. Traditionally, students who were not selected for a community with an NSS cutoff were selected into E6, Multi-engine, or Rotary-wing, with Rotary-wing receiving the lowest performers. This method of selection, while far from scientific, was accepted due to the fact that a Naval Flight Student (NFS) had to achieve a minimum NSS of 35 to advance from Primary Flight training. With the implementation of Multi-Pilot-Training- Syllabus (MPTS) in both Primary (2000), and Advanced Flight Training (2004), the minimum NSS requirement to advance from Primary Flight Training was removed. To ensure the lowest attrition rate possible without sacrificing the quality of students selected for rotary-wing, the consultants on this study sought to determine whether there should be a minimum NSS to select a NFS for the rotary-wing pipeline. This study analyzed data for a three-year period for students who selected Rotary-wing. Data for NFSs who were attrited for deficient performance was analyzed to determine their median and average NSS. The median and average NSS of a Helicopter Advanced training flight attrite was 35 with a standard deviation of 6.17. If a minimum NSS of 35 is applied it would have reduced the flight attrites by 21 students, or 55 percent, and overall attrition by 31 percent. This would have also resulted in a loss of 148 NFS over three years. Although applying a minimum NSS one standard deviation above the median would have reduced the number of flight attrites by 89 percent, it would also have adverse effects on student production by eliminating 432 students over the three-year period. Conclusions • This study serves as the starting point to transform a historically anecdotal argument on the validity of NSS correlation to NFS performance into an empirical and analytical discussion. • The statistical data supports establishing a minimum NSS of 35 to select Rotary-wing. Recommendations • Conduct additional research to determine the validity of establishing a minimum NSS for selecting Rotary-wing and determine the placement of lower performing NFSs. • Fleet Replacement Squadrons establish a database to record individual student performance in order to historically compare students.

Full textAbstract:
This thesis is a study of the development of investigatory select committees of the House of Commons during the twentieth century, with a particular emphasis on the period between 1960 and 1990. Synthesising existing analysis as well as presenting new evidence, it describes the early origins of such committees as an integral part of the work of the House, and then considers the Houseâs apparent loss of interest in select committees between 1920 and 1960. The thesis next discusses the reasons behind the introduction of new select committees in the mid-1960s, and traces further changes to committees during the 1970s. These developments are set in the political context of the period, and in particular the growth of backbench dissent in both major parties during the 1970s. The thesis then analyses the process by which departmentally-related select committees came to be established in 1979. Finally it assesses the quantitative and qualitative evidence about the activity and impact of the new departmental select committees in their first decade up to 1990, relating them closely to the political environment created by the government of Margaret Thatcher.

Full textAbstract:
Ansible brings select-to-edit functionality to physical widgets. When programming sets of physical widgets, it can be bothersome for a programmer to remember the name of the software object that corresponds to a specific widget. Click-to-edit functionality in GUI programming provides a physical action--moving the mouse to a widget and clicking a button on the mouse--to select a virtual widget. In a similar vein, when programming physical widgets, it is natural to point at a widget and think, "I want to program that one." Ansible allows physical user interface programmers to "click" on a physical widget by making a physical action: shining a light, waving a magnet, or pressing a button on the widget. This brings up the widget's code for editing on a laptop or workstation. The Ansible system is intended to help physical user interface programmers prototype distributed systems built from physical widgets. We conducted a user study with twelve programmers using Ansible; the study showed that shining a light eliminates the need for a programmer to remember the mapping between physical widgets and their names. We also built three example systems to illustrate some of the kinds of systems that can be implemented using Ansible.

Full textAbstract:
A dissertation submitted to the Faculty of Arts in partial fulfilment of the requirements for the degree of Master of Arts in the Department of English at the University of Zululand, South Africa, 2013.Polygamy is widely practised in African communities. The African social-realist novel, especially when it is woman-authored, shows female characters as having to play docile, subservient roles and accept demeaning positions in polygamous marriages. Although it has been claimed that traditional African marriage creates a satisfactory situation for women, mainly by means of the security it offers and the bonds that it forges between co-wives, the narrators of African realist novels almost always expose only evils associated with polygamy. In most of the texts, co-wives experience conflict with one another, not bonds. Men are portrayed as egocentric beings that greedily satisfy their sexual impulses at the expense of women. Encouraged by their families, they inflict irreparable emotional damage not only on their accumulated wives but often also on their offspring. While blinded by their desires, these men engender many unplanned children for whom they usually take little fatherly responsibility. Consequently, children too are objects of pity in many of the books. This dissertation, by means of close analysis of select African narratives, reveals that, despite all the struggles for liberation and democracy, values highly regarded in modern societies, polygamy is a prevailing sign of male dominance in African communities today. The dissertation shows that even such male-authored novels as Chinua Achebe’s Things Fall Apart and Onuora Nzekwu’s High Life For Lizards fail to recommend a polygamous life to women, while Mariama Bâ ’s So Long a Letter and Scarlet Song, Buchi Emecheta’s The Joys of Motherhood and Kehinde, Es’kia Mphahlele’s Chirundu, Lazarus Miti’s The Prodigal Husband, Ama Ata Aidoo’s Changes, Sue Nyathi’s The Polygamist,SembeneOusmane’s Xala, Lola Shoneyin’s The Secret Lives of Baba Segi’s Wives, Rebecca HourwichReyher’s Zulu Woman, Miriam KWere’s The Eighth Wife, T.M. Aluko’s One Man One Wife and Aminata Sow Fall’s The Beggars’Strike all use polygamy to highlight the incongruence between the ideals of democracy and the facts of life as experienced by African women. These texts reflect real social problems. They cast light on the inequalities that prevail in polygamous relationships and imply that the principle of equality cannot be achieved as long as polygamy exists.

Full textAbstract:
This research investigates how to improve legacy queries. Legacy queries are queries that programmers have coded and are used in applications. A database application typically has tens to hundreds of such queries. One way to improve legacy queries is to add new, interesting queries that are similar to or based on the set of queries. We propose Query AutoAwesome, a tool to generate new queries from legacy queries. The Query AutoAwesome philosophy is taken from Google’s AutoAwesomizer tool for photos, which automatically improves a photo uploaded to Google by animating the photo or adding special effects. In a similar vein, Query AutoAwesome automatically enhances a query by ingesting a database and the query. Query AutoAwesome produces a set of enhanced queries that a user can then choose to use or discard. A key problem that we solve is that the space of potential enhancements is large, so we introduce objective functions to narrow the search space to a tractable space. We describe our plans for implementing Query AutoAwesome and discuss our ideas for future work.

Full textAbstract:
Significant characteristic of any VLSI design circuit is its power, reliability, operating frequency and implementation cost. Dynamic CMOS designs provide high operating speeds compared to static CMOS designs combined with low silicon area requirement. This thesis describes the design and the optimization of high performance carry select adder. Previous researchers believed that existing CSA designs has reached theoretical speed bound. But, only a considerable portion of hardware resources of traditional adders are used in worst case scenario. Based on this observation our proposed design will improve on theoretical limit. The major scope of this proposed design is to increase the speed of carry generation between intermediate blocks of Carry select Adder (CSA) by introducing fast multiple clock Domino Manchester carry chain (MCC) that generates carry outputs. This design technique will have some advantages compared to pre-existing implementations in operating speed and power delay product. Simulation has been done using GPDK (Generic Process Design Kits) technology using cadence virtuoso. Thus the proposed technique provides advantages over pre-existing techniques in terms of operating speed.

Full textAbstract:
Polycyclic aromatic hydrocarbons (PAHs) are environmentally significant
because of their ubiquity and the toxicity of some. Their recalcitrance and persistence
makes them problematic environmental contaminants. Microbial degradation is
considered to be the primary mechanism of PAH removal from the environment.
Biodegradation kinetics of individual PAHs by pure and mixed cultures have been
reported by several researchers. However, contaminated sites commonly have complex
mixtures of PAHs whose individual biodegradability may be altered in mixtures.
Biodegradation kinetics for fluorene, naphthalene, 1,5-dimethylnaphthalene and 1-
methylfluorene were evaluated in sole substrate systems, binary and ternary systems
using Sphingomonas paucimobilis EPA505. The Monod model was fitted to the data
from the sole substrate experiments to yield biokinetic parameters, (qmax and Ks). The
first order rate constants (qmax/Ks) for fluorene, naphthalene and 1,5-
dimethylnaphthalene were comparable, although statistically different. However, affinity
constants for the three compounds were not comparable. Binary and ternary experiments
indicated that the presence of another PAH retards the biodegradation of the co-occurring PAH. Antagonistic interactions between substrates were evident in the form of competitive inhibition, demonstrated mathematically by the Monod multisubstrate
model. This model appropriately predicted the biodegradation kinetics in mixtures using
the sole substrate parameters, validating the hypothesis of common enzyme systems.
Competitive inhibition became pronounced under conditions of: Ks1 << Ks, S1 >> Ks1
and S1 >> S. Experiments with equitable concentrations of substrates demonstrated the
effect of concentration on competitive inhibition. Ternary experiments with naphthalene,
1,5-dimethylnapthalene and 1-methylfluorene revealed preferential degradation, where
depletion of naphthalene and 1,5-dimethylnapthalene proceeded only after the complete
removal of 1-methylfluorene. The substrate interactions observed in binary and ternary
mixtures require a multisubstrate model to account for simultaneous degradation of
substrates. However, developing models that account for sequential degradation may be
useful in scenarios where PAHs may not be competitive substrates. These mixture
results prove that substrate interactions must be considered in designing effective
bioremediation strategies and that sole substrate performance is limited in predicting
biodegradation kinetics of complex mixtures.

Full textAbstract:
In this thesis, we investigated if reinforcement learning could be applied on elevator systems to improve performance. The performance was evaluated by the average squared waiting time for the passengers, and the buildings considered were apartment buildings. The problem of scheduling elevator cars is an NP-hard problem, and no optimal solution is known. Therefore, an approach where the system learns a strategy instead of using a heuristic, should be the easiest way to get near an optimal solution. A learning system was constructed, where the system was trained to use the best scheduling algorithm out of five in a given situation, based on the prevailing traffic. The purpose of this approach was to reduce the training time that was required in order to get good performance and to lower the complexity of the system. A simulator was then developed, in which the different algorithms were implemented and tested in four different scenarios, where the size of the building and the number of elevator cars varied. The results generated by the simulator showed that reinforcement learning is a great strategy to use in buildings with 16 floors and three or four elevator cars. However, reinforcement learning did not increase the performance in buildings with 10 floors and two to three elevator cars. A possible reason for this is that the variation in performance between the different scheduling algorithms was too small in these scenarios.I denna rapport har vi undersökt huruvida reinforcement learning är användbart för att öka prestandan för hissystem i lägenhetshus. Prestandan bedömdes efter de genomsnittliga kvadrerade väntetiderna för resenärerna. Schemaläggningsproblemet för hissar är NP-svårt och ingen optimal lösning är känd. Att lösa problemet med hjälp av ett system som lär sig hur det ska agera, bör således vara en enklare strategi för att komma nära den optimala lösningen än att använda sig av en heuristik. Ett självlärande system konstruerades, där systemet tränades att använda den bäst lämpade schemaläggningsalgoritmen med avseende på rådande trafikförhållanden. Det fanns totalt fem olika algoritmer att välja bland. Anledningen till att detta gjordes i stället för att systemet skulle lära sig en komplett strategi, var för att sänka träningstiden som krävdes för att åstadkomma bra resultat och för att minska komplexiteten. En simulator utvecklades sedan, där de olika algoritmerna implementerades och testades på fyra olika scenarion, där storleken på byggnaden och antalet hissar varierade. Resultaten som genererades visade att reinforcement learning fungerar utmärkt på byggnader med 16 våningar och tre eller fyra hissar. På byggnader med tio våningar och två till tre hissar är det dock inte lika användbart och där bör i stället enklare algoritmer användas. En möjlig förklaring till detta är att prestandaskillnaderna mellan algoritmerna var för små under dessa scenarion.

In the last years, the use of machine learning methods has increased remarkably and therefore the research in this field is becoming more and more important. Despite this fact, a high uncertainity when using machine learning models is still present. We have a wide variety of machine learning approaches such as decision trees or support vector machines and many applications where machine learning has been proved useful like medical diagnosis or computer vision, but all this possibilities make finding the best machine learning approach for a given application a time consuming and not welldefined process since there is not a rule that tells us what method to use for a given type of data.We attempt to build a system that, using machine learning, is capable to learn the best machine learning approach for a given application. For that, we are working on the hypothesis that similar types of data will have also the same machine learning approachas best learner. Classification algorithms will be the main focus of this research and different statistical measures will be used in order to find these similarities among the data.

Great Plains rivers are unique systems that vary from large, continental scale, to small intermittent streams with grain sizes that range from bedrock to cobbles to silt. These rivers have been subject to widespread hydrologic alteration both within the channel and the watershed, which has resulted in an alteration in their hydrologic and geomorphic regimes. Although there is an acknowledgement of this alteration, to date there has not been a synthesis of the hydrology of Great Plains rivers or of their longitudinal morphologies. Chapters in this dissertation provide, to my knowledge, the first comprehensive analyses of the hydrology and morphology of Great Plains rivers over a range of spatial and temporal scales. In the first study, I found that there was no uniform pattern of hydrologic alteration throughout the Great Plains, which is likely attributable to variable system-specific reservoir management objectives, land use changes, and climatic regimes over the large area the Great Plains encompass. Results of this study are the first to quantify the widespread hydrologic alteration of Great Plains rivers following impoundment. In the second study, I found an apparent decoupling between local moisture conditions and streamflow in intermittent prairie streams. Results of this study used statistical models to identify relationships between flow intermittence, mean annual flow, and flood flow characteristics with moisture to characterize flow in an intermittent prairie stream. In the final study, I found that the downstream trends in hydraulic geometry and substrate characteristics of the Ninnescah River were consistent with the expected trends proposed by hydraulic geometry and substrate theories. However, there were points that deviated from the expected trends, most notably where a substantially large tributary enters the Ninnescah River and as the Ninnescah River approaches the Arkansas River, and causal explanations for these deviations were explored. Results of this study are, to my knowledge, the first of its kind to assess the longitudinal hydraulic geometry and substrate characteristics of a large sand-bed river over a large spatial scale. To our knowledge, there have been no comparable studies exist that attempted to describe hydrologic and geomorphic characteristics of prairie streams.

Students enrolled in Roanoke County Schools in 2003 became voluntary participants in the Communities That Care Youth Survey (CTCYS), which had been administered to a group (N = 3022) of 6th through 12th graders. The students answered multiple choice questions to determine their attitudes concerning many important topics within their home, school, and community domains. The carefully documented evaluation was conducted to determine the significance of two protective factors, which were employed to explain associations between students who stated that their parents had clear alcohol, tobacco, and drug use rules in the home as well as those who stated they frequently attended religious services and activities, termed parent efficacity and religiosity, respectively. Because risk factors are common among adolescents and few well-designed studies are addressing the benefits of parent efficacity or religiosity as protective factors, this study analyzed the CTCYS data utilizing meta-analyses to assess the efficacy of these two environmental factors in relation to students’ expressed perceptions of smoking cigarettes as a popular adolescent risk activity. Variables are unique to each individual and sample, therefore, multiple factors demonstrating risk and protective qualities were measured using a 0 to 8 point Likert summated rating scale. The various areas were examined according to frequency of risk behavior (i.e., smoking status - current, past, or never). Findings yielded statistically conclusive relationships within the participant responses using Chi-square analysis at the 0.05 level (2-sided), indicating a significant level of interaction between the select protective factors and tobacco use study variables.Ph.

Full textAbstract:
This thesis is concerned with literature’s engagement with the environment, specifically ecosystems and climate change. Literature of the fantastic, works that break from the tradition of mimetic literature and the limits of realism, are the focus of this thesis, which argues, alongside ecocriticism, that literature must be part of the interdisciplinary drive towards greater ecological awareness. Speculative literature adds fantastic elements or draws on scientific extrapolations into the future, and offers a platform to engage with the science of environmental issues alongside philosophical engagements with the relationship between humans and the more-than-human world around them. This thesis draws on ecocriticism to examine the role of reading and criticism in constructing more ecologically sustainable societies. From this position, it asks how fantasy can be used to convey these themes. As a result, this thesis is interested in definitions of fantasy, drawing on science fiction and fantasy to examine Kathryn Hume’s framework of the fantastic impulse. Placing fantastic texts on two axes, Hume examines the ways texts support or subvert the reader’s expectations, and encourage or discourage reflection on their extratextual worlds. This thesis contends that, texts that encourage engagement are most transformative, but that the spectrum of engagement and disengagement challenges authors to navigate between didacticism and emotive imagery. To show this, this thesis examines four series of novels drawing on the fantastic impulse. Frank Herbert’s Dune Chronicles, Kim Stanley Robinson’s Mars Trilogy and Science in the Capital, and George R.R. Martin’s A Song of Ice and Fire. The first two are on opposite ends of both of Hume’s axes, and imagine the challenges of constructing Earth-like ecosystems on other planets, asking questions about the sustainability of such a project as well as the possibilities of transforming society. The latter two engage with rapid climate change, Robinson’s looking at contemporary climate change and Martin’s engaging with historical climate change. They interrogate the impact of the climate on human and more- than-human life, and reveal the tension between comforting didactic revisions of human- environment interactions and framework-disturbing alternate ways of relating to the environment. This tension is where the fantastic is powerful, allowing alternate visions to pierce sceptical readers’ defences.

Full textAbstract:
Many pharmaceutical drugs in use today were originally identified in plants from traditional medicine. However, there remain many plants in traditional medicine that produce confusing immune responses and are therefore unlikely candidates for pharmaceutical drugs. The effects of some of the traditional medicines that induce these confusing immune responses may now be explained by recent advances in the characterization of our immune system, namely in our understanding of the unique functions of the γδ T cell. These γδ T cell functions include tissue repair and homeostasis, cancer infiltration and clearance, pathogen detection and cytokine response, and antigen presentation. Although there are currently therapies being studied to increase the effector function of γδ T cells, these techniques are only active on a limited population of γδ T cells, the human Vδ2 subset. Although these cells are potent effectors against pathogens and some cancers, Vδ2 T cells demonstrate a restricted tissue distribution and limited effector function in other γδ T cell host defense responses. As such, we screened compound libraries and traditional medicines for agonists with activity encompassing alternative γδ T cell subsets. Tannins derived from select plant species are able to fulfill this role as demonstrated by the activation and expansion of γδ T cell subsets not responsive to current γδ T cell expansion therapies. The ability of tannins to expand these γδ T cell populations will potentially increase the therapeutic range of γδ T cells and may be used as treatments for wound healing as well as in the clearance of solid tumor cancers.

Resumo: Um dos grandes gargalos em sistemas de bancos de dados focados em leitura consiste em mover dados em torno da hierarquia de memória para serem processados na CPU. O movimento de dados é penalizado pela diferença de desempenho entre o processador e a memória, que é um problema bem conhecido chamado memory wall. O surgimento de memórias inteligentes, como o novo Hybrid Memory Cube (HMC), permitem mitigar o problema do memory wall executando instruções em chips de lógica integrados a uma pilha de DRAMs. Essas memórias possuem potencial para computação de operações de banco de dados direto em memória além do armazenamento de bancos de dados. O objetivo desta dissertação é justamente a execução do operador algébrico de seleção direto em memória para reduzir o movimento de dados através da memória e da hierarquia de cache. O foco na operação de seleção leva em conta o fato que a leitura de colunas a serem filtradas movem grandes quantidades de dados antes de outras operações como junções (ou seja, otimização push-down). Inicialmente, foi avaliada a execução da operação de seleção usando o HMC como uma DRAM comum. Posteriormente, são apresentadas extensões à arquitetura e ao conjunto de instruções do HMC, chamado HMC-Scan, para executar a operação de seleção próximo aos dados no chip lógico do HMC. Em particular, a extensão HMC-Scan tem o objetivo de resolver internamente as dependências de instruções. Contudo, nós observamos que o HMC-Scan requer muita interação entre a CPU e a memória para avaliar a execução de filtros de consultas. Portanto, numa segunda contribuição, apresentamos a extensão arquitetural HIPE-Scan para diminuir esta interação através da técnica de predicação. A predicação suporta a avaliação de predicados direto em memória sem necessidade de decisões da CPU e transforma dependências de controle em dependências de dados (isto é, execução predicada). Nós implementamos a operação de seleção próximo aos dados nas estratégias de execução de consulta orientada a linha/coluna/vetor para a arquitetura x86 e para nas duas extensões HMC-Scan e HIPE-Scan. Nossas simulações mostram uma melhora de desempenho de até 3.7× para HMC-Scan e 5.6× para HIPE-Scan quando executada a consulta 06 do benchmark TPC-H de 1 GB na estratégia de execução orientada a coluna. Palavras-chave: SGBD em Memória, Cubo de Memória Híbrido, Processamento em Memória.
Abstract: A large burden of processing read-mostly databases consists of moving data around the memory hierarchy rather than processing data in the processor. The data movement is penalized by the performance gap between the processor and the memory, which is the well-known problem called memory wall. The emergence of smart memories, as the new Hybrid Memory Cube (HMC), allows mitigating the memory wall problem by executing instructions in logic chips integrated to a stack of DRAMs. These memories can enable not only in-memory databases but also have potential for in-memory computation of database operations. In this dissertation, we focus on the discussion of near-data query processing to reduce data movement through the memory and cache hierarchy. We focus on the select scan database operator, because the scanning of columns moves large amounts of data prior to other operations like joins (i.e., push-down optimization). Initially, we evaluate the execution of the select scan using the HMC as an ordinary DRAM. Then, we introduce extensions to the HMC Instruction Set Architecture (ISA) to execute our near-data select scan operator inside the HMC, called HMC-Scan. In particular, we extend the HMC ISA with HMC-Scan to internally solve instruction dependencies. To support branch-less evaluation of the select scan and transform control-flow dependencies into data-flow dependencies (i.e., predicated execution) we propose another HMC ISA extension called HIPE-Scan. The HIPE-Scan leads to less iteration between processor and HMC during the execution of query filters that depends on in-memory data. We implemented the near-data select scan in the row/column/vector-wise query engines for x86 and two HMC extensions, HMC-Scan and HIPE-Scan achieving performance improvements of up to 3.7× for HMC-Scan and 5.6× for HIPE-Scan when executing the Query-6 from 1 GB TPC-H database on column-wise. Keywords: In-Memory DBMS, Hybrid Memory Cube, Processing-in-Memory.

Full textAbstract:
Probabilistic-Write/Copy-Select (PWCS) is a novel synchronization scheme suggested by Nicholas Mc Guire which avoids expensive atomic operations for synchronizing access to shared objects. Instead, PWCS makes inconsistencies detectable and recoverable. It builds on the assumption that, for typical workloads, the probability for data races is very small. Mc Guire describes PWCS for multiple readers but only one writer of a shared data structure. In this paper, we report on the formal analysis of the PWCS protocol using a continuous-time Markov chain model and probabilistic model checking techniques. Besides the original PWCS protocol, we also considered a variant with multiple writers. The results were obtained by the model checker PRISM and served to identify scenarios in which the use of the PWCS protocol is justified by guarantees on the probability of data races. Moreover, the analysis showed several other quantitative properties of the PWCS protocol.

Full textAbstract:
This thesis is an edition of and introduction and commentary to the text of a selection of Hellenistic Greek epigrams from the so-called Lithika (i.e. 'On Stones') by the Hellenistic poet, Posidippus of Pella, preserved in the first section of a third century BC Milan papyrus bookroll (P Mil Vogl VIII 309) first published in 2001. The thesis includes an introduction, Part 1, which discusses and contextualises the epigrams with other ancient Greek mineralogical literature (such as Theophrastus' On Stones) and also maps out the poetics of the poems. The main part of the thesis, the edition and commentary, Part 2, provides literary and archaeological notes on nine of the twenty (sometimes badly preserved) epigrams about precious stones: AB 3, AB 4, AB 5, AB 8, AB 11 ,AB 13 ,AB 14, AB 16 and AB 17. Tracings of the papyrus' readings and proposed supplements (not included in the editio princeps), which allow checking of the available spacing, are included for select epigrams as an appendix, and show that many supplements printed in the text of the two previous editions are unsubstantiated or wrong. The new text presented here thus furnishes those interested in Hellenistic epigram with a new foundation on which to base further discussion of the poetry.

Full textAbstract:
Magíster en Ciencias, Mención ComputaciónLas estructuras de datos compactas ofrecen funcionalidad y acceso a los datos usando poco espacio. En una estructura de datos plana se conservan los datos en su forma original y se busca minimizar el espacio extra usado para proveer la funcionalidad, mientras que en una estructura comprimida además se recodifican los datos para comprimirlos. En esta tesis se estudian estructuras de datos compactas para secuencias de bits (bitmaps) que proveen las operaciones rank y select: rankb(B,i) cuenta el número de bits b ∈ {0,1} en B[1..i] y selectb(B,i) retorna la posición de la i-ésima ocurrencia de b en B. En teoría ambas consultas se pueden responder en tiempo constante, pero la implementación práctica de estas soluciones no siempre es directa o con buenos resultados empíricos. Las estructuras de datos con un enfoque más práctico, usualmente no óptimas en teoría, pueden tener mejor desempeño que implementaciones directas de soluciones teóricamente óptimas. Esto es particularmente notorio para la operación select. Además, las implementaciones más eficientes para rank son deficientes para select, y viceversa. En esta tesis se definen nuevas estructuras de datos prácticas para mejorar el desempeño de las operaciones de rank y select, basadas en dos ideas principales. La primera consiste en, a diferencia de las técnicas actuales, que usan estructuras separadas para rank y select, reutilizar cada estructura también para acelerar la otra operación. La segunda idea es simular en tiempo de consulta una tabla de resultados precomputados en vez de almacenarla, lo que permite utilizar tablas universales mucho mayores que las que sería posible almacenar. Los resultados experimentales muestran que la primera idea, aplicada a estructuras planas, utiliza sólo 3% de espacio sobre el bitmap y ofrece tiempos similares a estructuras que usan mucho más espacio, para ambas operaciones. En estructuras de datos comprimidas se pueden combinar ambas ideas, obteniendo un espacio extra de menos de 7 % sobre el bitmap comprimido y manteniendo, para ambas operaciones, tiempos similares o mejores que las estructuras actuales (que usan 27 % de espacio extra).

Full textAbstract:
During recent decades, venture capital has been an important source of financing of high-growing ventures. Many studies have focused on the question that how venture capital investors select their investment targets. However, there is little attention to the issue that how entrepreneurs select investors. When entrepreneurs select the right investors, the venture’s chances of success improve and thus, this issue is also important to study. The successful relationship between entrepreneurs and venture capital investors is indeed a strong indicator of the venture’s success.
The purpose of this study is to contribute the research knowledge of how Finnish entrepreneurs select business angels and venture capitalists. The literature review conducts the fundamentals of firm growth and venture capital financing. The empirical data was gathered in five semi-structured interviews from four case companies that have raised venture capital. First, the empirical analysis describes the fundraising process of entrepreneurs. Second, it is discussed that how entrepreneurs select investors in different stages of the process and what is their selection criteria.
The results of this study indicate that Finnish entrepreneurs in early-stage ventures cannot afford to refuse a good offer from the investors. However, the investors should fill certain requirements in order that entrepreneurs view the offer to be good. In fact, this study finds seven issues that entrepreneurs consider important when they are seeking venture capital: valuation, terms and conditions, personal compatibility, trust, ability to invest in future, amount of money invested and value-added services. Entrepreneurs do not value these criteria equally and they are more flexible with certain criteria.
This study extends of research on entrepreneurs’ selection process and criteria to a new geographical and cultural context, as this study focuses on Finnish entrepreneurs and the venture capital market in Finland. Overall, this study encourages the future researchers to study the entrepreneur’s side of the venture capital market. The understanding of it is still limited.

Full textAbstract:
The Role of Religion in Ancient Civilizations: Select Readings addresses the importance of religion in ancient civilizations and encourages readers to evaluate these civilizations both historically and critically. The selected readings help readers understand civilizations as whole systems with not only social and political characteristics, but also religious ones. Topics include the establishment of patriarchal civilizations, Mesopotamian and Egyptian religion, and the early civilizations of Northwest India. Students also learn about the religions of ancient China and Japan, traditional African religions and belief systems, religion and burial in Roman Britain, and the great temples of Meso-American religions. The final selections are devoted to early Christianity, the Byzantine Empire, and Islam. Original introductions place the readings in context. Taken as a whole, these carefully curated articles demonstrate both the uniqueness of each religion and the traditions and practices that, over time, became interconnected and sometimes even fused to form new religions. The Role of Religion in Ancient Civilizations is well-suited to survey courses in world and ancient religions, as well as classes on religious history and the history of the ancient world.

Full textAbstract:
This study was conducted in two trials. The aim was firstly to identify the qualitative characteristics of Atriplex nummularia (Hatfield Select). Goats and sheep were used to identify three palatability groups of plants in the A. nummularia (Hatfield Select) paddock. These palatability groups were compared in terms of quality to one another. Secondly, qualitative and quantitative intakes of A. nummularia (Hatfield Select) by goats and sheep were determined. This was done in a grazing trial lasting five days. A comparison was conducted between goats and sheep as well as between the different days of the grazing period. During the first trial, goats and sheep were used to identify the most-, medium- and least-palatable A. nummularia (Hatfield Select) plants. The regrowth on these plants were harvested and used for laboratory analysis to identify the qualitative differences between these three groups. These samples were also used to determine and compare degradability between the three groups as well as between goats and sheep. Goats and sheep preferred A. nummularia (Hatfield Select) plants with a significantly (p ¡Ü 0.05) higher crude protein (CP), phosphorus (P) and magnesium (Mg) content. The most preferred plants also had higher neutral detergent fibre (NDF), Ca, K, Na, Cl- and Cu content than the least preferred plants, but these were not significant (p > 0.05). A. nummularia (Hatfield Select) provides enough CP for maintenance and production in both goats and sheep. All mineral requirements for maintenance in goats and sheep can be satisfied on A. nummularia (Hatfield Select), except that of Cu. For production (growth and lactation) only P is deficient and needs to be supplemented. A. nummularia (Hatfield Select) makes an ideal drought fodder crop to support the natural veld during the dry season. An overall higher DM, N and NDF rumen degradability of Atriplex was recorded with goats than with sheep. Goats exhibited a significantly (p ¡Ü 0.05) higher DM and N degradation and although a higher NDF degradation was also recorded, this was not significant. The rate of DM, N and NDF rumen degradation was also higher in goats than in sheep. This means that goats have a more favorable rumen environment for the digestion of A. nummularia (Hatfield Select). DM and N degradation were also significantly (p ¡Ü 0.05) higher in the most palatable group than the least palatable group. NDF degradability decreased with palatability. This means that the most palatable plants have a higher digestibility and quality than the least palatable plants. In the second experiment, rumen and oesophageal fistulated sheep and goats were allowed to graze A. nummularia (Hatfield Select) for five days. Qualitative and quantitative intakes were determined. The quality and quantity of ingested material were compared between goats and sheep as well as between the different grazing days. There was a significant decline in the quality and quantity of intake over the grazing period. Some parameters were significant, for example CP. The CP concentration declined from 18% to 3.91 % for goats and from 19.88% to 6.61% for sheep. The cell wall constituents (NDF) increased by about 10% from the start to the end of the grazing period. IVDOM decreased by 14% and intakes were almost halved from the start to the end of the grazing period. Other authors have also observed this decrease in quality and quantity of intake over time. The lower quality and quantity in intake was because of a decline in the availability of high quality edible material. At the end of the grazing period, there was very little edible material left which caused an extremely low quality and quantity of intake. Rumen NH3-N concentrations also declined as the dietary CP declined, but it was still present in high enough concentrations to sustain the rumen micro flora population. Rumen VFA decreased over the grazing period. The acetic acid to propionic acid ratio increased towards the end of the grazing period. This caused a decline in the efficiency of utilization of ME for maintenance as acetic acid has an efficiency in utilization of ME of 59% and propionic acid of 86% (McDonald et al., 1995). This means that energy will have to be supplemented to sustain maintenance.Dissertation (MSc (Agric) Animal Science, Nutrition)--University of Pretoria, 2007.
