Agent Collaborative Target Localization and Classification in Wireless Sensor Networks

Wireless sensor networks (WSNs) are autonomous networks that have been frequently deployed to collaboratively perform target localization and classification tasks. Their autonomous and collaborative features resemble the characteristics of agents. Such similarities inspire the development of heterogeneous agent architecture for WSN in this paper. The proposed agent architecture views WSN as multi-agent systems and mobile agents are employed to reduce in-network communication. According to the architecture, an energy based acoustic localization algorithm is proposed. In localization, estimate of target location is obtained by steepest descent search. The search algorithm adapts to measurement environments by dynamically adjusting its termination condition. With the agent architecture, target classification is accomplished by distributed support vector machine (SVM). Mobile agents are employed for feature extraction and distributed SVM learning to reduce communication load. Desirable learning performance is guaranteed by combining support vectors and convex hull vectors. Fusion algorithms are designed to merge SVM classification decisions made from various modalities. Real world experiments with MICAz sensor nodes are conducted for vehicle localization and classification. Experimental results show the proposed agent architecture remarkably facilitates WSN designs and algorithm implementation. The localization and classification algorithms also prove to be accurate and energy efficient.

Professional researcher or a ‘good guest’? Ethical dilemmas involved in researching children and families in the home setting

In this article we explore our experiences of researching children and families in the home setting. We trace the impact of the home setting on some ethical and methodological issues which arose in the course of conducting our field work and consider issues of consent, confidentiality, power, leaving the field and specifically our dilemmas, both personal and professional, around researcher identity. We suggest that our dilemmas can be encapsulated as a struggle between the conflicting requirements of the professional researcher and the ‘good guest’. Drawing upon our interviews with over 100 children and families in the Home School Knowledge Exchange (HSKE) project, we pose questions about the relationship between the researcher and the families. In reflecting on our own experiences we draw on the work of other social researchers and in addition we consider the function and efficacy of professional codes of practice to prepare and protect researchers and respondents in the field.
Sequence Comparison of the Ty1 and Ty2 Elements of the Yeast Genome Supports the Structural Model of the tRNAiMet–Ty1 RNA Reverse Transcription Initiation Complex

In the reverse transcription initiation complex of the yeast Ty1 retrotransposon, interaction between the template RNA and primer tRNAiMet is not limited to base pairing of the primer binding site (PBS) with ten nucleotides at the 3′ end of tRNAiMet but three regions named boxes 0, 1 and 2.1 interact with the T and D stems and loops of tRNAiMet. Sequence comparison of 33 Tyl elements and 13 closely related Ty2 elements found in the yeast genome shows that the nucleotide sequence of all elements is highly conserved in the region spanning the PBS and the three boxes. Since this domain of the template RNA encodes a portion of protein TyA, we have calculated its amino acid profile and its nucleotide profile to evaluate the role played by nucleotide sequence conservation in the selection for TyA function and in the maintenance of base pairing interactions for the priming function of Tyl RNA. Our results show that the nucleotide sequence conservation of Ty1 RNA is constrained not only by selection for Ty1 function but also by maintenance of a given nucleotide sequence able to base pair with the tRNAiMet in the primer–template initiation complex. © John Wiley & Sons, Ltd.
Exploring preschoolers’ engagement and perceived physical competence in an autonomy-based object control skill intervention

The purpose of this study was to describe children’s engagement during two (high and low) autonomy-based climates. Twenty-five preschool children participated in a nine-week object control skill intervention. Children completed the object control subscale of the Test of Gross Motor Development 2nd Edition and the perceived physical competence subscale of Harter and Pike’s Pictorial Scale of Perceived Competence and Social Acceptance (1984). Skill attempts were tallied by video analyses. A skill attempt was considered appropriate if the movement was consistent with the correct execution of the skill and the goal of the task. Findings indicate (a) no significant difference in appropriate skill attempts between each climate, (b) no significant difference in appropriate skill attempts of low- and high- skilled children in each climate, (c) regardless of climate, children improved in object control percentile and low-skilled children improved significantly more than high-skilled children, and (d) high-autonomy group children significantly improved in pre- to post- intervention on perceived competence compared to the low-autonomy group, regardless of skill level. High-autonomy climates provide variations of task difficulty that may promote the development of perceived physical competence of preschool children.
Research into the Development of Voice Assessment in Music Therapy

Dansk resume. I denne afhandling undersoges det, om det er muligt at konstruere et stemmeassessmentredskab (Voice Assesment Pro fi le - herefter forkortet VOIAS), der kan dokumentere forandring over tid med validitet og reliabilitet, og som bygger pa principperne for evidensbaseret praksis (Wigram et al. 2002), og om det vha VOIAS er muligt at indhente relevante informationer til klinisk musikterapeutisk praksis og til det tvaerfaglige behandlingsteam. En forelobig litteraturgennemgang viste, at der ikke fandtes et sadant redskab inden for musikterapi, og at kun lidt forskning inden for musikterapi fokuserede pa og omhandlede den menneskelige stemme. Konsekvensen af denne opdagelse var, at jeg matte konstruere et sadan stemmeassessmentredskab og fastlaegge de procedurer, der matte vaere omkring implementeringen af et sadant redskab. Derfor fokuserede den endelige litteraturgennemgang pa at indsamle information om mulige stemmeparametre, samt udvaelgelse og de fi nition af disse med det formal at konstruere en kvantitativ pro fil , der kunne evaluere den menneskelige stemme i musikterapi. Jeg vurderede, at det for at sikre et godt grundlag for udvaelgelsen af parametrene var nodvendigt at studere den musikterapeutiske litteratur om brugen af den menneskelige stemme i klinisk praksis som et primaert instrument, savel som en gennemgang af udvalgte studier af stemmen fra specialer og fra fagomrader uden for det musikterapeutiske felt. Litteraturgennemgangen afslorede et pafaldende fravaer af opmaerksomhed pa den menneskelige stemme i musikterapi og den menneskelige stemmes potentiale som kilde til at indsamle informationer om klientens psykiske tilstand og e ff ekten af en musikterapeutisk behandling baseret pa stemmeterapeutisk arbejde.
Understanding and Responding to People Who Sexually Abuse Children Whilst Employed in Positions of Trust: An Overview of the Relevant Literature – Part Two: Organisations

For the purposes of this review of the literature this population was defined as anyone working with children who had sexually offended against a child or young person in a context directly related to their paid work or volunteering activity. Working with children here is used to include people working with children in health, social welfare, education, residential accommodation, leisure, sporting, religious activities and criminal justice systems and extends to the voluntary and private sectors (Beyer et al., 2005). The term is further extended to include managers. Worker will be used as a generic term to describe anyone in this category.
Teachers' Stories of Change: Stress, Care and Economic Rationality.

The impact of economic rationalism on teachers’ working lives has been documented extensively, particularly in the UK. This article provides a case study of its impact in the early 1990s in a small Australian state, Tasmania, to illustrate that although the particular institutional forms through which it is expressed may differ its impact is similar. We do this by focusing on teachers' stories of change that have stress as a major theme. Stress is partially explained by increased workloads, teachers teaching outside their specialist areas and a changing student population. However, the ideology of economic rationalism has heightened stress because of the perceived lack of administrative care. A major stressor is trying to maintain a professional ideology of caring while, concurrently, accommodating to economic rationality. The clash of ideologies leads teachers to reduce commitment by leaving teaching, moving to part-time employment, withdrawing into classroom teaching and/or rationalising their workload with, they perceive, a decrease in the quality of teaching.
The Cik1/Kar3 Motor Complex Is Required for the Proper Kinetochore–Microtubule Interaction After Stressful DNA Replication

In budding yeast Saccharomyces cerevisiae, kinetochores are attached by microtubules during most of the cell cycle, but the duplication of centromeric DNA disassembles kinetochores, which results in a brief dissociation of chromosomes from microtubules. Kinetochore assembly is delayed in the presence of hydroxyurea, a DNA synthesis inhibitor, presumably due to the longer time required for centromeric DNA duplication. Some kinetochore mutants are sensitive to stressful DNA replication as these kinetochore proteins become essential for the establishment of the kinetochore–microtubule interaction after treatment with hydroxyurea. To identify more genes required for the efficient kinetochore–microtubule interaction under stressful DNA replication conditions, we carried out a genome-wide screen for yeast mutants sensitive to hydroxyurea. From this screen, cik1 and kar3 mutants were isolated. Kar3 is the minus-end-directed motor protein; Cik1 binds to Kar3 and is required for its motor function. After exposure to hydroxyurea, cik1 and kar3 mutant cells exhibit normal DNA synthesis kinetics, but they display a significant anaphase entry delay. Our results indicate that cik1 cells exhibit a defect in the establishment of chromosome bipolar attachment in the presence of hydroxyurea. Since Kar3 has been shown to drive the poleward chromosome movement along microtubules, our data support the possibility that this chromosome movement promotes chromosome bipolar attachment after stressful DNA replication.
A Dynamic Random Graph Model for Diameter-Constrained Topologies in Networked Systems

Random graphs have been widely investigated in the literature because of their relevance to many scientific domains. In this brief, the attention is focused on diameter-constrained random graphs, which are useful in analyzing unstructured overlays for delay-bounded network applications and systems. To this end, a general process of arrivals is considered, which describes the sequence of vertex couples (i.e., node couples) among which a path composed of no more than D edges (i.e., links) has to be established. Accordingly, a topology formation mechanism M is formulated, expressing the rules that drive the addition of new edges, obeying to the constraint on the maximum diameter D. Third, using graph-theoretic arguments, an original discrete-time model is proposed, which describes the evolution of the average network degree (i.e., the average number of edges per node) subject to M and D. Fourth, the model is successfully validated using computer simulations in a wide range of scenarios (with up to 216 nodes). Finally, concrete examples are provided to illustrate useful applications of the proposed approach, also in the presence of link failures.
CT Angiographic Source Images: Flow- or Volume-Weighted?

BACKGROUND AND PURPOSE: CTA-SI have been previously reported to correlate with CBV. We hypothesized that CTA-SI performed by modern multisection CT scanners are CBF-, not CBV-weighted. MATERIALS AND METHODS: Sixty-four consecutive patients with anterior circulation stroke symptoms were selected from a stroke data base between June 2007 and January 2009. Two independent blinded readers calculated defect volumes of CTA-SI and PCCT, CBF, and CBV images. Spearman correlation of lesion volumes was performed. Linear regression and residual analysis demonstrated factors associated with outliers for CTA or PCCT for CBF and CBV volumes. RESULTS: We found a strong positive correlation between CTA with CBF (r = 0.89, P < .0001) and between PCCT and CBV (r = 0.79, P < .0001). CTA to CBV (r = 0.5, P < .0001) and PCCT to CBF (r = 0.52, P < .0001) correlations were weaker. Positive CTA outliers had lower ASPECTS (P = .01), larger baseline CTA (149 ± 46 cm3 versus 83 ± 32 cm3; P = .002, respectively), and final infarct (190 ± 100 cm3 versus 80 ± 50 cm3; P = .09, respectively) volumes than nonoutliers. No baseline features were significantly related to PCCT outliers. There was no difference in the vessel occlusion sites for positive or negative outliers for CTA or PCCT (P = .55 and P = 1.00, respectively). CONCLUSIONS: Our results indicate that CTA-SI are CBF- rather than CBV-weighted.
Films of Carbon Nanomaterials for Transparent Conductors

The demand for transparent conductors is expected to grow rapidly as electronic devices, such as touch screens, displays, solid state lighting and photovoltaics become ubiquitous in our lives. Doped metal oxides, especially indium tin oxide, are the commonly used materials for transparent conductors. As there are some drawbacks to this class of materials, exploration of alternative materials has been conducted. There is an interest in films of carbon nanomaterials such as, carbon nanotubes and graphene as they exhibit outstanding properties. This article reviews the synthesis and assembly of these films and their post-treatment. These processes determine the film performance and understanding of this platform will be useful for future work to improve the film performance.
The Fourth Wave of Feminism: Psychoanalytic Perspectives Introductory Remarks

This introductory paper traces a century of 4 waves of feminism from a psychoanalytic perspective. The first phase focused on political change as the suffragette movement was undertaken at the turn of the 20th century by feminist activists who lobbied successfully for women's right to vote; the second phase, a broad sociopolitical-cultural movement located in the 1960s and 1970s, focused on consciousness-raising around gender issues, women's liberation (Betty Friedan, Kate Millet, Simone de Beauvoir, Bela Abzug, Gloria Steinem), and job and economic parity. With sexual freedom and job opportunities more established for women, the third phase evolved in the 1980s and 1990s, emphasizing women exploring gender pluralities; “having it all”; and juggling career, sex, and motherhood. The fourth wave moved into the 21st century as women turned toward spiritual concerns about the planet and all its beings, putting themselves in the service of the world, ecology, and the downtrodden.
Massive Catalog Index based Search for e-Catalog Matching

In e-commerce environment, business partners exchange product information in the form of e-catalogs. Since each business player uses his/her own classification and identification code for describing e-catalogs, it is not easy to match his/her product with the e-catalog requested by his/her partner. To date, these matches have been accomplished through the manual work of domain experts. Therefore, many attempts have been made to create a standard to solve this problem. This research focuses on improving the e-catalog information match process in order to integrate and exchange catalogs among various e-catalog systems. We suggest an index structure, MCI (massive catalog index), which is optimized for searching large heterogeneous e-catalog databases. MCI is capable of searching vast catalog databases quickly as well as recommending precise e-catalog matches.
Comparative transcriptomics of 5 high-altitude vertebrates and their low-altitude relatives

Abstract Background Species living at high altitude are subject to strong selective pressures due to inhospitable environments (e.g., hypoxia, low temperature, high solar radiation, and lack of biological production), making these species valuable models for comparative analyses of local adaptation. Studies that have examined high-altitude adaptation have identified a vast array of rapidly evolving genes that characterize the dramatic phenotypic changes in high-altitude animals. However, how high-altitude environment shapes gene expression programs remains largely unknown. Findings We generated a total of 910 Gb of high-quality RNA-seq data for 180 samples derived from 6 tissues of 5 agriculturally important high-altitude vertebrates (Tibetan chicken, Tibetan pig, Tibetan sheep, Tibetan goat, and yak) and their cross-fertile relatives living in geographically neighboring low-altitude regions. Of these, ∼75% reads could be aligned to their respective reference genomes, and on average ∼60% of annotated protein coding genes in each organism showed FPKM expression values greater than 0.5. We observed a general concordance in topological relationships between the nucleotide alignments and gene expression–based trees. Tissue and species accounted for markedly more variance than altitude based on either the expression or the alternative splicing patterns. Cross-species clustering analyses showed a tissue-dominated pattern of gene expression and a species-dominated pattern for alternative splicing. We also identified numerous differentially expressed genes that could potentially be involved in phenotypic divergence shaped by high-altitude adaptation. Conclusions These data serve as a valuable resource for examining the convergence and divergence of gene expression changes between species as they adapt or acclimatize to high-altitude environments.
Analysis of Human Carbonic Anhydrase II: Docking Reliability and Receptor-Based 3D-QSAR Study

The ability of Gold software to predict the binding disposition of carbonic anhydrase (CA) inhibitors was evaluated using CA II as a case study. The best procedure was subsequently used for docking almost 300 CA II ligands, and the best poses were used as an alignment tool for the development of a 3D quantitative structure-activity relationship (QSAR) study. Evaluation of the resulting 3D-QSAR model allowed us to indicate the ligand properties and residues important for CA II inhibition. Since CAs are an important target involved in many pathologies such as glaucoma, obesity, and tumors, the results obtained could accurately predict the binding affinity of newly designed CA II inhibitors. Furthermore, it is reasonable that this strategy could be profitably used also for the investigation of other CAs.
Implementing a Type Debugger for Scala

Statically-typed languages offer type systems that are less and less comprehensible for programmers as the language grows in complexity. In this paper, we present a type debugger, a tool that enables analysis of type-related problems as well as exploration of the typechecking process in general. We explain our findings on implementing a lightweight instrumentation mechanism for Scala, as well as guide the reader through some typical debugging scenarios in which one can use our tool. The type debugger visualizes the internals of the typechecker which we believe increases its chances of being a successful educational tool, and which simplifies understanding of statically-typed languages in general.
Measuring potential cues for depression in adolescents

So far, depression research has mainly relied on adult data and self-reports. For better prevention and treatment, it could be of great importance to diagnose additional behavioral cues in earlier stages of life. We therefore analysed video recordings of adolescents (low versus high risk groups with regard to developing depression) performing a free speech task using linguistic, nonverbal and acoustic methods of measurement. High risk adolescents used fewer words and talked more about home and family than their low risk counterparts, suggesting possible relations with introvert and attachment-related behavior. Nonverbally, females showed more affiliation and flight behavior than males, possibly reflecting gender-specific coping strategies. Moreover, interactions show gender differences between risk groups; high risk females use less words and more flight behavior than low risk females, whereas males show the exact opposite pattern. These findings might contribute to better prediction and treatment of depression in the future.
Addressing the intercultural via task-based language teaching: possibility or problem?

A frequent weakness of communicative approaches to foreign language teaching is a neglect of the intercultural dimension. Cultural knowledge is often treated as an addendum which focuses on learning facts about the target country. This article explores whether task-based language teaching (TBLT) can successfully address the intercultural dimension. Using findings that emerge from a series of one-to-one interviews, this article explores practitioners’ current understandings of cultural knowledge, and how these understandings influence their practices. It identifies strengths and weaknesses and considers the steps that may be necessary if TBLT is to be a more successful mediator of the intercultural dimension.
