Implementing Recommendation Algorithms for Decision Making Processes

This paperâ€™s contribution is placed into decision-making process research area. In our previous papers we showed how decision makerâ€™s behavior can be captured in logs and how an aggregated decision data model (DDM) can be mined. We now introduce two recommendation algorithms that rely on a DDM. Each algorithm aims to steer the decision makerâ€™s actions towards a fully informed decision by suggesting the next action to be performed. The first algorithm is a Greedy approach that recommends the most frequent activities performed by other decision makers. The second algorithm is inspired from A* path finding algorithm. It finds a decision sub-objective and tries to guide the decision maker on the path to it. We eval-uate these algorithms by comparing them with each other and to the classical association rules approach. It is not our intention to recommend the better decision alternative. We want to make sure the decision makers made an informed decision by correctly and completely evaluating all alternatives. This is an extended version of the paper published at IE 2012 Conference.
On the Effectiveness of Manual and Automatic Unit Test Generation

The importance of testing has recently seen a significant growth, thanks to its benefits to software design (e.g. think of test-driven development), implementation and maintenance support. As a consequence of this, nowadays it is quite common to introduce a test suite into an existing system, which was not designed for it. The software engineer must then decide whether using tools which automatically generate unit tests (test suites necessary foundations) and how. This paper tries to deal with the issue of choosing the best approach. We will describe how different generation techniques (both manual and automatic) have been applied to a real case study. We will compare achieved results using several metrics in order to identify different approaches benefits and shortcomings. We will conclude showing the measure how the adoption of tools for automatic test creation can shift the trade-off between time and quality.

Baseline characteristics of climate, permafrost and land cover from a new permafrost observatory in the Lena River Delta, Siberia (1998-2011)

Samoylov Island is centrally located within the Lena River Delta at 72° N, 126° E and lies within the Siberian zone of continuous permafrost. The landscape on Samoylov Island consists mainly of late Holocene river terraces with polygonal tundra, ponds and lakes, and an active floodplain. The island has been the focus of numerous multidisciplinary studies since 1993, which have focused on climate, land cover, ecology, hydrology, permafrost and limnology. This paper aims to provide a framework for future studies by describing the characteristics of the island's meteorological parameters (temperature, radiation and snow cover), soil temperature, and soil moisture. The land surface characteristics have been described using high resolution aerial images in combination with data from ground-based observations. Of note is that deeper permafrost temperatures have increased between 0.3 to 1.3 °C over the last five years. However, no clear warming of air and active layer temperatures is detected since 1998, though winter air temperatures during recent years have not been as cold as in earlier years.
Prescription of secondary prevention medications, lifestyle advice, and referral to rehabilitation among acute coronary syndrome inpatients: results from a large prospective audit in Australia and New Zealand

Objective To evaluate the proportion of patients hospitalised with acute coronary syndrome (ACS) in Australia and New Zealand who received optimal inpatient preventive care and to identify factors associated with preventive care. Methods All patients hospitalised bi-nationally with ACS were identified between 14–27 May 2012. Optimal in-hospital preventive care was defined as having received lifestyle advice, referral to rehabilitation, and prescription of secondary prevention pharmacotherapies. Multilevel multivariable logistic regression was used to determine factors associated with receipt of optimal preventive care. Results For the 2299 ACS survivors, mean (SD) age was 69 (13) years, 46% were referred to rehabilitation, 65% were discharged on sufficient preventive medications, and 27% received optimal preventive care. Diagnosis of ST elevation myocardial infarction (OR: 2.64 [95% CI: 1.88–3.71]; p<0.001) and non-ST elevation myocardial infarction (OR: 1.99 [95% CI: 1.52–2.61]; p<0.001) compared with a diagnosis of unstable angina, having a percutaneous coronary intervention (PCI) (OR: 4.71 [95% CI: 3.67–6.11]; p<0.001) or coronary bypass (OR: 2.10 [95% CI: 1.21–3.60]; p=0.011) during the admission or history of hypertension (OR:1.36 [95% CI: 1.06–1.75]; p=0.017) were associated with greater exposure to preventive care. Age over 70 years (OR:0.53 [95% CI: 0.35–0.79]; p=0.002) or admission to a private hospital (OR:0.59 [95% CI: 0.42–0.84]; p=0.003) were associated with lower exposure to preventive care. Conclusions Only one-quarter of ACS patients received optimal secondary prevention in-hospital. Patients with UA, who did not have PCI, were over 70 years or were admitted to a private hospital, were less likely to receive optimal care.
‘Have a Quiet, Orderly, Polite Revolution’: Framing Political Protest and Protecting the Status Quo

This paper demonstrates how print media sources frame the Tea Party and Occupy Wall Street in ways that, consciously or not, support the prevailing status quo – social, economic, and political elites. The study employs critical discourse analysis (CDA) as the analytic framework, investigating how print media (sometimes referred to as ‘print capitalism’) utilized framing techniques that disparaged the two political organizations but in very different ways. The analysis incorporates articles appearing in the New York Post and the New York Times from the inception of each organization, through six weeks after the 2012 Presidential Inauguration; articles were coded to uncover themes that defined both organizations as ‘outsiders. ’ Tea Partiers are characterized as irrational demagogues, while Occupy Wall Street (OWS) activities are criminalized; both are dismissed as irrelevant, leaving the predominant ‘mainstream’ political rule intact. Findings identify tools of discourse used by media to limit the influence of competing movements while essentially protecting the status quo. Revealing these tools provides clues to unreliable discourse in media coverage of presidential candidates, which tends to quash open debate and threaten principles of participatory government.
Application Performance Analysis of Distributed File Systems under Cloud Computing Environment

The processing efficiency of data-intensive application on Hadoop with the general-purpose distributed file system such as Lustre, as the backend file system, is not clear. This paper focuses on the similarities and differences between Lustre and HDFS (Hadoop Distributed File System). We propose a Hadoop-Lustre platform and evaluate the performance differences of Lustre and HDFS by using a set of data-intensive computing benchmarks. Experimental results indicate Lustre can reach parity with HDFS, or even better than HDFS if the much faster network interconnect is available. It is necessary to study non-HDFS distributed file system to make up the performance lack of HDFS in some MapReduce-based application scenarios.
Efficient Dynamic Load Balancing for Structured P2P Network

Many types of structured p2p networks have been developed in recent years. We are also studying a scalable structured p2p network: Waon (Well-distributed Algorithm for an Overlay Network). Waon supports dynamic load balancing, range queries, data aggregation and locality awareness services, so we can make many types of network services on a Waon's network. Dynamic load balancing mechanism of Waon, however, is not efficient because each node uses only partial knowledge of the network. In this paper, we propose an efficient dynamic load balancing scheme for Waon. The proposed scheme uses an aggregation mechanism in order to understand the whole situation, and makes plans of load balancing by using the aggregation results. We describe about a concept of the proposed scheme, and we also explain its algorithm in this paper.
Characterization of HelD, an interacting partner of RNA polymerase from Bacillus subtilis

Bacterial RNA polymerase (RNAP) is an essential multisubunit protein complex required for gene expression. Here, we characterize YvgS (HelD) from Bacillus subtilis, a novel binding partner of RNAP. We show that HelD interacts with RNAP-core between the secondary channel of RNAP and the alpha subunits. Importantly, we demonstrate that HelD stimulates transcription in an ATP-dependent manner by enhancing transcriptional cycling and elongation. We demonstrate that the stimulatory effect of HelD can be amplified by a small subunit of RNAP, delta. In vivo, HelD is not essential but it is required for timely adaptations of the cell to changing environment. In summary, this study establishes HelD as a valid component of the bacterial transcription machinery.
Whole Transcriptome Profiling of Maize during Early Somatic Embryogenesis Reveals Altered Expression of Stress Factors and Embryogenesis-Related Genes

Embryogenic tissue culture systems are utilized in propagation and genetic engineering of crop plants, but applications are limited by genotype-dependent culture response. To date, few genes necessary for embryogenic callus formation have been identified or characterized. The goal of this research was to enhance our understanding of gene expression during maize embryogenic tissue culture initiation. In this study, we highlight the expression of candidate genes that have been previously regarded in the literature as having important roles in somatic embryogenesis. We utilized RNA based sequencing (RNA-seq) to characterize the transcriptome of immature embryo explants of the highly embryogenic and regenerable maize genotype A188 at 0, 24, 36, 48, and 72 hours after placement of explants on tissue culture initiation medium. Genes annotated as functioning in stress response, such as glutathione-S-transferases and germin-like proteins, and genes involved with hormone transport, such as PINFORMED, increased in expression over 8-fold in the study. Maize genes with high sequence similarity to genes previously described in the initiation of embryogenic cultures, such as transcription factors BABY BOOM, LEAFY COTYLEDON, and AGAMOUS, and important receptor-like kinases such as SOMATIC EMBRYOGENESIS RECEPTOR LIKE KINASES and CLAVATA, were also expressed in this time course study. By combining results from whole genome transcriptome analysis with an in depth review of key genes that play a role in the onset of embryogenesis, we propose a model of coordinated expression of somatic embryogenesis-related genes, providing an improved understanding of genomic factors involved in the early steps of embryogenic culture initiation in maize and other plant species.

Efficient Routing Implementation of Programmable Network on Chip on FPGA using Circuit Switching Approach

More and more complex and larger system on chips are getting developed as a result of increase in chip density following Moore's law. Advanced SoCs have in their shelf significantly noticeable communication mechanisms. NoC has solved the scalability problems to a larger extent compared to bus based interconnect. NoC has been providing a back bone infrastructure for System-on-chips since long. Among the available communication matrices NoC has helped tremendously in the communication performance enhancement. NoC research majorly involves work on packet switching, though at the same time circuit switching assures high communication rates and predictable communication latencies. The current research is targeted towards implementation of NoC architecture for FPGA based designs using circuit switching approach. Proposed implementation is termed as enhancement of light weight circuit switched architecture. The programmable NoC architecture is being implemented using VHDL and synthesized on the Virtex-5 XC5VLX20T package FF323 device at 139 MHz. It provides sufficient customization on the number of ports, nodes and amount of data. Performance improvement over the existing implementations has been validated by the experimental synthesized results.
Ontology Integration with Non-Violation Check and Context Extraction

Matching and integrating ontologies has been a desirable technique in areas such as data fusion, knowledge integration, the Semantic Web and the development of advanced services in distributed system. Unfortunately, the heterogeneities of ontologies cause big obstacles in the development of this technique. This licentiate thesis describes an approach to tackle the problem of ontology integration using description logics and production rules, both on a syntactic level and on a semantic level. Concepts in ontologies are matched and integrated to generate ontology intersections. Context is extracted and rules for handling heterogeneous ontology reasoning with contexts are developed. Ontologies are integrated by two processes. The first integration is to generate an ontology intersection from two OWL ontologies. The result is an ontology intersection, which is an independent ontology containing non-contradictory assertions based on the original ontologies. The second integration is carried out by rules that extract context, such as ontology content and ontology description data, e.g. time and ontology creator. The integration is designed for conceptual ontology integration. The information of instances isn't considered, neither in the integrating process nor in the integrating results. An ontology reasoner is used in the integration process for non-violation check of two OWL ontologies and a rule engine for handling conflicts according to production rules. The ontology reasoner checks the satisfiability of concepts with the help of anchors, i.e. synonyms and string-identical entities; production rules are applied to integrate ontologies, with the constraint that the original ontologies should not be violated. The second integration process is carried out with production rules with context data of the ontologies. Ontology reasoning, in a repository, is conducted within the boundary of each ontology. Nonetheless, with context rules, reasoning is carried out across ontologies. The contents of an ontology provide context for its defined entities and are extracted to provide context with the help of an ontology reasoner. Metadata of ontologies are criteria that are useful for describing ontologies. Rules using context, also called context rules, are developed and in-built in the repository. New rules can also be added. The scientific contribution of the thesis is the suggested approach applying semantic based techniques to provide a complementary method for ontology matching and integrating semantically. With the illustration of the ontology integration process and the context rules and a few manually integrated ontology results, the approach shows the potential to help to develop advanced knowledge-based services.
Associated 21-cm H i absorption towards the radio galaxy 3C 452 (J2245+3941)

We report the detection of 21-cm H i absorption towards the core of the Fanaroff–Riley II radio galaxy 3C 452 (J2245+3941). The absorption profile is well resolved into three components; the strongest and narrowest component being coincident with the velocity corresponding to [O iii] emission lines while the other two components are blueshifted with respect to it by ∼30 and ∼115 km s−1. If the systemic velocity of the host galaxy is determined from low-ionization lines, which are redshifted with respect to the [O iii] doublet by about ∼200 km s−1, then both the [O iii] emission and the 21-cm absorption lines are associated with outflowing material. The neutral hydrogen column density is estimated to be N(H i) = 6.39 × 1020 (Ts/100) (fc/1.0)−1cm−2, where Ts and fc are the spin temperature and partial coverage of the background source, respectively. If the 21-cm absorber is also responsible for the nuclear extinction at infrared wavelengths and X-ray absorption, then for a spin temperature of ∼8000 K the absorber occults only ∼10 per cent of the radio core.
A modified I2TSWTCM to improve bandwidth fairness in Diffserv

The enhanced time sliding window based Three Color Marker (I2tswTCM), improves bandwidth fairness in Differentiated Services network by providing a proportional fair share of the excess network bandwidth among TCP aggregates. This improvement in fairness is obtained by introducing an adaptive factor based on which the yellow packets are injected into the network. However, the fairness performance is found to vary with respect to `gamma', a constant in this factor. Further, deterioration in fairness occurs as the number of aggregates increase in the network. Hence in this paper, an attempt has been made to circumvent the above fairness issue by replacing `gamma' of I2tswTCM with an adaptive factor that depends on PIR, the number of aggregates and the bandwidth of the network. By this proposed scheme compared to I2tswTCM, more yellow packets are injected into the network in case of excess bandwidth, thereby improving fairness. The algorithm with the modification has been presented and simulations have been carried out with the proposed scheme using NS-2. The results show that the proposed marker is insensitive not only to the number of flows in the aggregate but also to the number of aggregates in the network.
Shifting the Focus of Survivability : Back to the Basics

This research introduces a new paradigm to survivability. The philosophy of the approach is to consider a hierarchical solution space, where survivability features for speci c attacks are applied at the lowest suitable level. Whereas the hierarchy as a whole is assumed to represent a comprehensive solution, each level is limited in scope to deal with attacks which have speci c characteristics. Some attacks have such evident characteristics at a speci c level, that survivability features can be applied with very high degree of certainty. The focus of this paper is on solutions at the lowest level of complexity. Speci cally, we address the strength of signature based attack recognition and recovery at the kernel level. This method has been successfully demonstrated in a survivability architecture based on the Linux operating system.
Geographies of retailing and consumption: markets in motion

While I began my first of three reports on retailing and consumption (see Crewe, 2000;2001) bemoaning the early neglect of these topics across a number of academicdisciplines, I start my final report with an altogether different lament, namely that therehas been a recent surfeit of writings on markets, material culture and consumption.While this is no bad thing in itself, I use the word lament purposefully in order to signalmy concern about the insightfulness of some of this work (see also Miller, 2001, on thediscrepancy between the quantity and quality of recent consumption research). In thediscussion that follows, I do not propose to launch into a critique of all that is bad inconsumption studies, nor to write in the style of an annotated bibliography of consumerstudies. I am also purposefully side-stepping the now locked-in and tired refrain of‘let’s join economy and culture’, through either ‘unveiling’ commodity chains(Hartwick, 1998; Goldman and Papson, 1998) or via circuits and networks (Jackson,2002: 8). Rather, in what follows I attempt to construct a series of arguments about theconcept of the market as one way of framing and organizing what are currentlydisparate lines of inquiry. It seems to me that what unites much of the better literaturein the field at present is a concern for the ways in which particular forms of exchangeare accomplished, represented, spatialized and institutionalized (Carrier, 1997; Dilley,1992; Philo and Miller, 2001; Slater and Tonkiss, 2001: 199). A number of differentmodels of markets and exchange seem to be emerging which, in different ways, mighthelp to develop our theorization of the connections between commodities, consumersand their spatial and temporal worlds.
Life, work and sustainable learning practices: a study on a small business network

Knowledge and knowing processes as work and life practices are not univocal. They are not related to knowledge as an autonomous body of propositions, but permeated with new identities and action modes, which are continuously formed, promoting learning opportunities. The objective of this research is formulated in the understanding of this shift between knowing and knowledge when describing practical learning in everyday work life, reflecting on the implications of this social labor process on small business network sustainability. A qualitative case study approach was used. In line with the theoretical and epistemological choices that guided this research, we decided to use an analysis of discursive practices approach and, accordingly, data collection was based on triangulation techniques in favor of interpretation enrichment. The knowledge to act, revealed in the analysis, suggested that organizations are social worlds forming a standard that holds life, work and organizational practices together. They negotiate, circulate, transform and reproduce, forming a network of actors and favoring sustainable practices learning.
