Recent results in automatic Web resource discovery

Classical information retrieval (IR) is concerned with indexing a collection of documents and answering queries by returning a ranked list of relevant documents [14, 21, 24]. With the growth of the web, the problems of ambiguity, context sensitivity, synonymy (two terms with the same meaning) and polysemy (one term with different meanings) that are inherent in natural languages, together with the abundance of web pages related to prominent topics, have exacerbated the difficulty of fulfilling the user’s information need. Most search sites have added directory-based topic browsing. The web is organized as a tree of topics, similar to the Dewey decimal system, the Library of Congress catalog, or the US Patent and Trademarks Office subject codes. Tree nodes are maintained by paid ontologists and/or specialist volunteers, such as at Yahoo! , The Mining Co., WWW Virtual Library, and Open Directory Project. This strategy may be biased because of sparsity of experts; at any rate it is biased away from the most accomplished and busiest people.
BindingDB and ChEMBL: online compound databases for drug discovery

Public domain repositories of compound structures and activity data are indispensable tools for many aspects of pharmaceutical research, especially in academic environments. Such databases provide essential resources for structure-activity data mining and the evaluation of chemoinformatics and drug design methods. They are also important to support scientific interactions between commercial and academic environments. This editorial highlights two major public domain compound data repositories, BindingDB and ChEMBL, which have different origins. BindingDB has evolved in an academic setting (and continues to be developed there) and ChEMBL in a biotechnology environment. The ChEMBL database is now maintained and further developed at the European Bioinformatics Institute Outstation of the European Molecular Biology Laboratory. These databases mostly contain structures and activity data taken from the scientific literature, covering different stages of compound exploration and optimization efforts, and provide a substantial body of complementary compound activity information. Together with PubChem bioassays, ChEMBL and BindingDB provide the foundation of compound data analysis in the public domain.

Congestion Control Approach based on Effective Random Early Detection and Fuzzy Logic

Congestion in router buffer increases the delay and packet loss. Active Queue Management (AQM) methods are able to detect congestion in early stage and control it by packet dropping. Effective Random Early Detection (ERED) method, among many other AQM methods, gives a good performance in detect and control congestion and preserve packet loss. However, the ERED neglect the delay factor, which is effect the performance of the network. Moreover, ERED has a real parameterization problem. Several parameters have to be initialized to optimal values to obtain satisfactory results. This paper proposed an extended ERED method that considers the delay in its process and combines the extended ERED method with a Fuzzy Inference Process that eases the problem of parameter initialization. The results show that the parametric-based form of the proposed work gives a better performance results, according to the performance measures, delay, dropping and packet loss. The loss has been enhanced by 10-100%. Delay has been enhanced by 30-60%. The performance of the fuzzy-based form of the proposed method is better than the parametric-based form and ERED in terms of delay and packet loss.
An Assessment of Academic Stress among Undergraduate Students: The Case of University of Botswana.

This research finding is based on the responses obtained from the undergraduate students at a higher learning institution (University) in Botswana. This paper investigated the stressors, symptoms and effects that are likely to be experienced by the undergraduate students in higher institutions (Universities). Stressors related to time, academic pressure, and academic environments were explored. A total of 320 students participated in this study. Data was collected through self-administered questionnaires that were randomly distributed to the students during lecture time. Data obtained was analysed using descriptive statistics and Tables. The open ended question was thematically analysed and the result presented in Table 5. It was found out that, academic workload, inadequate resources, low motivation, poor performance in academic, continuous poor performance in academic, overcrowded lecture halls, and uncertainty of getting job after graduating from the university lead to stress among students. It is hoped that, these findings will help the individual students, lecturers, career and counselling centres, and the university administrators to put in place mechanisms that mitigate the effects of stress at the University. In addition, the finding will also spur a scholarly debate on academic stress among students in higher institutions. We therefore suggest that, other researchers should consider using triangulation method. The limitation of our study was the sample size and lack of geographical coverage since our study only concentrated on one university. Therefore, the findings of this study cannot be generalised and as such the researchers suggest replication of this study using larger samples from other parts of the world to validate our findings. Key words: Students, higher institutions, university, stress, stressors.
Labor Market Returns to Sub-Baccalaureate Credentials

This study provides one of the first estimates of the returns to different types of community college credentials—short-term certificates, long-term certificates, and associate degrees—across different fields of study. We exploit a rich data set that includes matched, longitudinal college transcripts and Unemployment Insurance records for students who entered a Washington State community college in 2001–2002. Our findings based on an individual fixed effect model suggest that earning an associate degree or a long-term certificate is associated with increased wages, particularly for women. We find that there is greater variation in returns to wages by the field of study than by degree type.
FIVIS bicycle simulator: an immersive game platform for physical activities

The objective of the FIVIS project is to develop a bicycle simulator which is able to simulate real life bicycle ride situations as a virtual scenario within an immersive environment. A sample test bicycle is mounted on a motion platform to enable a close to reality simulation of turns and balance situations. The visual field of the bike rider is enveloped within a multi-screen visualization environment which provides visual data relative to the motion and activity of the test bicycle. This implies the bike rider has to pedal and steer the bicycle as they would a traditional bicycle, while forward motion is recorded and processed to control the visualization. Furthermore, the platform is fed with real forces and accelerations that have been logged by a mobile data acquisition system during real bicycle test drives. Thus, using a feedback system makes the movements of the platform reflect the virtual environment and the reaction of the driver (e.g. steering angle, step rate).
CUrATIon PEDAgogy for M EDIA STUDIES: (fUrThEr) TowArDS ThE InEx PErT

An educational 'model' for participatory learning and media literacy in the contemporary context of digitally mediated lifeworlds is emerging (Jenkins, 2010; Gauntlett, 2011; Fraser and Wardle, 2011). The critical problem, we argue, for its 'adequacy' is the privilege granted to curriculum content and skills over pedagogy. Elsewhere, we offered a 'pedagogy of the inexpert' as such a model for text- conscious disciplines such as, but not restricted to, Media Studies. This strategy removes 'the media' from our gaze and looks awry to develop new ways of working with students - to 'show and tell' textual agency and more reflexive deconstruction of what it is to read and make media, and to 'be' in mediation. In this article, we develop this approach further towards a model of 'curation'. Understood in this way, students 'show' media literacy in new spaces - not by recourse to skills, competences or analytical unmasking of the properties of a (contained) text, but by exhibiting, by curating a moment in time of textual meaning- making and meaning-taking, but with a mindfulness - a critical acceptance of such an attempt to hold and curate the flow of meaning as an artifice.
Synchronization of multi-scroll attractor using Extended Kalman Filter based approach

Attractors have always been an area of great interest for researchers for its wide variety of applications since the discovery of chaotic attractors. Lately, a new type of attractors was discovered (derived from chaotic attractor) having many scrolls in their phase plane plot differing from traditional chaotic attractors having generally two scrolls. In this paper, synchronization of multi-scroll systems using Extended Kalman Filter, in presence of process noise and measurement noise is presented. This synchronization can be used for systems used in secure communication and many other applications. To illustrate the effectiveness of this synchronization scheme, numerical example based on two different multi-scroll attractors is presented with elaborate simulation results.
Dirichlet-Based Trust Management for Effective Collaborative Intrusion Detection Networks

The accuracy of detecting intrusions within a Collaborative Intrusion Detection Network (CIDN) depends on the efficiency of collaboration between peer Intrusion Detection Systems (IDSes) as well as the security itself of the CIDN. In this paper, we propose Dirichlet-based trust management to measure the level of trust among IDSes according to their mutual experience. An acquaintance management algorithm is also proposed to allow each IDS to manage its acquaintances according to their trustworthiness. Our approach achieves strong scalability properties and is robust against common insider threats, resulting in an effective CIDN. We evaluate our approach based on a simulated CIDN, demonstrating its improved robustness, efficiency and scalability for collaborative intrusion detection in comparison with other existing models.
Second Language Figurative Proficiency: A Comparative Study of Malay and English

This paper explores the potential of cognitive linguistic notions such as conceptual metaphor and conceptual metonym for comparing the figurative phraseologies of English and Malay and anticipating second language learner difficulty. A comparative analysis is undertaken that identifies six types of relationship between figurative expressions in the two languages. It is suggested that identification of linguistic and conceptual similarities and differences in figurative expressions enable us to anticipate the types of problems that may be encountered by Malay-speaking learners of English in the acquisition of English figurative language. A comparative analysis is used to develop a set of production and comprehension tasks that aim to measure figurative proficiency. This is tested with a group of 36 Malay-speaking tertiary learners of English. It is found that figurative expressions with an equivalent conceptual basis and linguistic form are the easiest. The most difficult are those with (1) a different conceptual basis and an equivalent linguistic form and (2) culture-specific expressions that have a different conceptual basis and a different linguistic form. There is some evidence that learners may resort to the L1 conceptual basis when processing unfamiliar L2 figurative language. There is also evidence of intralingual confusion between higher and lower frequency L2 figurative expressions. It is more advantageous to draw learners' attention to the conceptual bases of L2 figurative expressions in circumstances where they differ from those of the L1 than when the conceptual bases are similar (especially where learners' L1 is unrelated to their L2).
The Metagenomic Telescope

Next generation sequencing technologies led to the discovery of numerous new microbe species in diverse environmental samples. Some of the new species contain genes never encountered before. Some of these genes encode proteins with novel functions, and some of these genes encode proteins that perform some well-known function in a novel way. A tool, named the Metagenomic Telescope, is described here that applies artificial intelligence methods, and seems to be capable of identifying new protein functions even in the well-studied model organisms. As a proof-of-principle demonstration of the Metagenomic Telescope, we considered DNA repair enzymes in the present work. First we identified proteins in DNA repair in well–known organisms (i.e., proteins in base excision repair, nucleotide excision repair, mismatch repair and DNA break repair); next we applied multiple alignments and then built hidden Markov profiles for each protein separately, across well–researched organisms; next, using public depositories of metagenomes, originating from extreme environments, we identified DNA repair genes in the samples. While the phylogenetic classification of the metagenomic samples are not typically available, we hypothesized that some very special DNA repair strategies need to be applied in bacteria and Archaea living in those extreme circumstances. It is a difficult task to evaluate the results obtained from mostly unknown species; therefore we applied again the hidden Markov profiling: for the identified DNA repair genes in the extreme metagenomes, we prepared new hidden Markov profiles (for each genes separately, subsequent to a cluster analysis); and we searched for similarities to those profiles in model organisms. We have found well known DNA repair proteins, numerous proteins with unknown functions, and also proteins with known, but different functions in the model organisms.
How to Conquer Information Overload? Supporting Financial Decisions by identifying Relevant Conference Call Topics

The ever rising amount of business communications results in a growing amount of qualitative data relevant to many decision situations. This increase in information volume and velocity threatens to overburden decision makers. We provide a structured approach towards this problem using topic-models to reduce information overload by filtering content and by providing context-relevant information to decision makers. Building upon theoretical considerations related to phases of the decision process established by Herbert A. Simon, we implement the proposed approach on the example of a large document collection of stock analyst reports and analyst conference calls using Latent Dirichlet Allocation (a topic model). Thereby, we extract investment-relevant topics from the model and discuss the opportunities for decision support resulting from the chosen approach.
Dual Derivatization and GC–MS Analysis of Phenolic Compounds Suspected of Being Xenoestrogens

Abstract A procedure has been specifically designed to characterize suspect phenolic xenoestrogens in derivatized form by GC–MS. Methyl and trimethylsilyl derivatives of phenolic compounds were sequentially subjected to GC–MS. The mass spectral information derived from the molecular ion allowed the determination of the number of reactive hydroxyl groups and the molecular weight of the parent phenol.
Reversal of breast cancer resistance protein (BCRP/ABCG2)‐mediated drug resistance by novobiocin, a coumermycin antibiotic

Breast cancer resistance protein (BCRP/ABCG2) of an ATP‐binding cassette half‐transporter confers resistance against mitoxantrone and camptothecin derivatives of topotecan and irinotecan. Novobiocin, a coumermycin antibiotic, is known to enhance anticancer drug sensitivity of cancer cells in vitro and in vivo, the mechanism of which remains undetermined. Here we focused on drug efflux pump and examined whether novobiocin reversed drug resistance in multidrug‐resistant cells highly expressing BCRP. To explore the reversal mechanisms, intracellular drug accumulation was measured by flow cytometry, and a topotecan transport study using plasma membrane vesicles was performed. We used PC‐6/SN2‐5H2 small cell lung cancer and MCF‐7/MX breast cancer cells selected with SN‐38 of the active irinotecan metabolite and mitoxantrone, respectively, and the BCRP cDNA transfectant MCF‐7/clone 8 cells. These cells expressed high levels of BCRP mRNA but not other known transporters. Compared to the parental PC‐6 cells, PC‐6/SN2‐5H2 cells were 141‐, 173‐ and 57.2‐fold resistant to topotecan, SN‐38 and mitoxantrone, respectively. Novobiocin at 60 μM decreased the degree of the above resistance by approximately 26‐fold in PC‐6/SN2‐5H2 cells, and similarly reversed resistance in MCF‐7/MX, MCF‐7/clone 8 and un‐selected NCI‐H460 cells highly expressing BCRP. Furthermore, novobiocin increased the intracellular topotecan accumulation in these cells and inhibited the topotecan transport into the membrane vesicles of PC‐6/SN2‐5H2 cells. No effects of novobiocin in these assay were observed in the parental PC‐6 and MCF‐7 cells. The kinetic parameters in the transport study indicated that novobiocin was a inhibitor for BCRP, resulting in competitive inhibition of BCRP‐mediated topotecan transport. These findings suggest that novobiocin effectively overcomes BCRP‐mediated drug resistance at acceptable concentrations. © 2004 Wiley‐Liss, Inc.

Acute Ischemic Stroke Treatment, Part 2: Treatment “Roles of Capillary Index Score, Revascularization and Time”

Due to recent results from clinical intra-arterial treatment for acute ischemic stroke (IAT-AIS) trials such as the interventional management of stroke III, IAT-AIS and the merit of revascularization have been contested. Even though intra-arterial treatment (IAT) has been shown to improve revascularization rates, a corresponding increase in good outcomes has only recently been noted. Even though a significant percentage of patients achieve good revascularization in a timely manner, results do not translate into good clinical outcomes (GCOs). Based on a review of the literature, the authors suspect limited GCOs following timely and successful revascularization are due to poor patient selection that led to futile and possibly even harmful revascularization. The capillary index score (CIS) is a simple angiography-based scale that can potentially be used to improve patient selection to prevent revascularization being performed on patients who are unlikely to benefit from treatment. The CIS characterizes presence of capillary blush related to collateral flow as a marker of residual viable tissue, with absence of blush indicating the tissue is no longer viable due to ischemia. By only selecting patients with a favorable CIS for IAT, the rate of GCOs should consistently approach 80–90%. Current methods of patient selection are primarily dependent on time from ischemia. Time from cerebral ischemia to irreversible tissue damage seems to vary from patient to patient; so focusing on viable tissue based on the CIS rather than relying on an artificial time window seems to be a more appropriate approach to patient selection.
Parental Acceptance, Parental Stress, and Quality of Life: A study with parents of ADHD children

Adapting to a child with attention deficit hyperactivity disorder (ADHD) represents a great challenge for any family, and especially for the parents. Considering the psychological and behavioral issues inherent to this disorder, it’s no easy task to promote the child’s development, in a supportive way, while at the same time ensuring that it is well adjusted to all social contexts. More difficult yet is to achieve this while maintaining high quality of interpersonal relations and psychological health in the family. In this context, our research’s objectives were to assess and analyze possible connections between the perception of parental acceptance and rejection, parental stress and quality of family life, in families with children with ADHD. To achieve our goals we applied the Parental Acceptance-Rejection Questionnaire (PARQ, Rohner, 2005), the Quality of Life Scale (QOL, Barnes & Olson, 1982), and the Parental Stress Scale (PSS, Mixao, Leal & Maroco, 2007) to a sample of 57 Portuguese parents, both fathers and mothers, of, at least, one child diagnosed with ADHD. Our results show that parents of children with ADHD perceive themselves as accepting of their children, and the majority present low levels of parental stress. Also, we found that the more stressed parents feel about parenting, the less accepting they perceive themselves to be, as well as having lower levels of quality of life. These results leave interesting pointers for future research andintervention, suggesting the importance of helping parents of ADHD children to deal with stress as it seems to have an important role on key dimensions of family functioning and consequently on children’s socio-emotional adjustment and development.
