Rating Knowledge Sharing in Cross-Domain Collaborative Filtering

Cross-domain collaborative filtering (CF) aims to share common rating knowledge across multiple related CF domains to boost the CF performance. In this paper, we view CF domains as a 2-D site-time coordinate system, on which multiple related domains, such as similar recommender sites or successive time-slices, can share group-level rating patterns. We propose a unified framework for cross-domain CF over the site-time coordinate system by sharing group-level rating patterns and imposing user/item dependence across domains. A generative model, say ratings over site-time (ROST), which can generate and predict ratings for multiple related CF domains, is developed as the basic model for the framework. We further introduce cross-domain user/item dependence into ROST and extend it to two real-world cross-domain CF scenarios: 1) ROST (sites) for alleviating rating sparsity in the target domain, where multiple similar sites are viewed as related CF domains and some items in the target domain depend on their correspondences in the related ones; and 2) ROST (time) for modeling user-interest drift over time, where a series of time-slices are viewed as related CF domains and a user at current time-slice depends on herself in the previous time-slice. All these ROST models are instances of the proposed unified framework. The experimental results show that ROST (sites) can effectively alleviate the sparsity problem to improve rating prediction performance and ROST (time) can clearly track and visualize user-interest drift over time.
REWARDING FACULTY SCHOLARSHIP AT TWO‐YEAR COLLEGES: INCENTIVE FOR CHANGE OR PERCEIVED THREAT?

Excellence in teaching is the hallmark of the community college. Research and publications, the traditional measures of faculty scholarship, generally have not been expected of faculty members at these two‐year institutions. Some community college educators advocate a scholarly role for faculty members, wherein scholarship is defined in the context of the teaching mission of the two‐year college. They have suggested that scholarship should be a facet of the faculty evaluation process. This article examines (a) two‐year college faculty members’ and administrators’ attitudes toward including scholarship criteria in the faculty reward systems and (b) their concerns about scholarship as an additional facet of faculty evaluation.
School Accountability and Professional Job Responsibilities: A Perspective From Secondary Principals

This article reports how secondary principals perceive the status of the accountability movement and their professional job responsibilities in the context of accountability. The data were collected frm a nationally representative sample of secondary principals during the Schools and Staffing Survey 1999-2000. Respondents reported that there were specific incentives or corrective measures for meeting performance goals, that numerous responsibilities were added to their traditional roles, that they paid substantial attention to instructional leadership, and that management tasks still occupied more time and energy than leadership initiatives.
NUKTI: English-Inuktitut Word Alignment System Description

Machine Translation (MT) as well as other bilingual applications strongly rely on word alignment. Efficient alignment techniques have been proposed but are mainly evaluated on pairs of languages where the notion of word is mostly clear. We concentrated our effort on the English-Inuktitut word alignment shared task and report on two approaches we implemented and a combination of both.
The role of socioeconomic status gradients in explaining differences in US adolescents' health.

OBJECTIVE This study sought to determine whether socioeconomic status (SES) gradients exist among US adolescents for self-rated health and for 5 diseases that cause serious adolescent and continuing adult morbidity. METHODS Baseline data from 15,483 adolescent and parental surveys from the National Longitudinal Study of Adolescent Health were used. SES indicators included parental education and occupation, and household income. Dependent variables included self-rated health and the presence of depression, obesity, asthma, suicide attempt in the past year, and prior sexually transmitted disease. RESULTS SES gradients were found for self-rated health, depression, and obesity (P < .01). Suicide attempt was linearly associated with income (P < .01). After adjustment for other SES and sociodemographic factors, education and income remained independent correlates of both depression and obesity; income remained an independent correlate of attempted suicide. CONCLUSIONS Differences in susceptibility to socially mediated etiologic mechanisms of disease may exist during adolescence. Understanding the sociostructural context and patterning of adolescents' lives is crucial to clearly understanding health and disease etiology throughout the course of life.
Role of Ongoing, Intrinsic Activity of Neuronal Populations for Quantitative Neuroimaging of Functional Magnetic Resonance Imaging-Based Networks

A primary objective in neuroscience is to determine how neuronal populations process information within networks. In humans and animal models, functional magnetic resonance imaging (fMRI) is gaining increasing popularity for network mapping. Although neuroimaging with fMRI-conducted with or without tasks-is actively discovering new brain networks, current fMRI data analysis schemes disregard the importance of the total neuronal activity in a region. In task fMRI experiments, the baseline is differenced away to disclose areas of small evoked changes in the blood oxygenation level-dependent (BOLD) signal. In resting-state fMRI experiments, the spotlight is on regions revealed by correlations of tiny fluctuations in the baseline (or spontaneous) BOLD signal. Interpretation of fMRI-based networks is obscured further, because the BOLD signal indirectly reflects neuronal activity, and difference/correlation maps are thresholded. Since the small changes of BOLD signal typically observed in cognitive fMRI experiments represent a minimal fraction of the total energy/activity in a given area, the relevance of fMRI-based networks is uncertain, because the majority of neuronal energy/activity is ignored. Thus, another alternative for quantitative neuroimaging of fMRI-based networks is a perspective in which the activity of a neuronal population is accounted for by the demanded oxidative energy (CMR(O2)). In this article, we argue that network mapping can be improved by including neuronal energy/activity of both the information about baseline and small differences/fluctuations of BOLD signal. Thus, total energy/activity information can be obtained through use of calibrated fMRI to quantify differences of ΔCMR(O2) and through resting-state positron emission tomography/magnetic resonance spectroscopy measurements for average CMR(O2).
Quantifying modified opinion strength: A fuzzy inference system for Sentiment Analysis

In Sentiment Analysis or Opinion Mining, automatic quantification of the strength of opinion, expressed on any feature is very important task. However, it is quite challenging to automatically quantify the strength of opinion words, whenever they get modified by adverbial modifiers. For example the intensity of an opinion word “beautiful” gets increased in “very beautiful”, gets decreased in “slightly beautiful” and complemented in “not beautiful”. In our work, we have designed a fuzzy inference system based on experimentally designed fuzzy membership functions and concepts of hedges to standardized and formulate the process of strength quantification of subjective sentences when strength of opinion word get modified by the presence of n-gram adverbial modifiers pattern in the sentence. Using our membership functions and considering the manually quantified opinion strength for n-gram adverbial modifiers pattern as a baseline, we observed that our fuzzy inference system is producing output values with a very small average root mean square error with the targeted baseline points.
The Arabidopsis Information Resource (TAIR): a model organism database providing a centralized, curated gateway to Arabidopsis biology, research materials and community

Arabidopsis thaliana is the most widely-studied plant today. The concerted efforts of over 11 000 researchers and 4000 organizations around the world are generating a rich diversity and quantity of information and materials. This information is made available through a comprehensive on-line resource called the Arabidopsis Information Resource (TAIR) (http://arabidopsis.org), which is accessible via commonly used web browsers and can be searched and downloaded in a number of ways. In the last two years, efforts have been focused on increasing data content and diversity, functionally annotating genes and gene products with controlled vocabularies, and improving data retrieval, analysis and visualization tools. New information include sequence polymorphisms including alleles, germplasms and phenotypes, Gene Ontology annotations, gene families, protein information, metabolic pathways, gene expression data from microarray experiments and seed and DNA stocks. New data visualization and analysis tools include SeqViewer, which interactively displays the genome from the whole chromosome down to 10 kb of nucleotide sequence and AraCyc, a metabolic pathway database and map tool that allows overlaying expression data onto the pathway diagrams. Finally, we have recently incorporated seed and DNA stock information from the Arabidopsis Biological Resource Center (ABRC) and implemented a shopping-cart style on-line ordering system.
Activities in Scrum Master Teams : Process Tailoring in Large Enterprise Projects

This paper explores practitioner descriptions of agile method tailoring in large-scale offshore or outsourced enterprise projects. Specifically, tailoring of the scrum master role is investigated. The scrum master acts as a facilitator for software development teams, nurturing adherence to agile practices and removing impediments for team members. But in large projects, scrum masters work together in, often geographically distributed, scrum master teams. Scrum master teams use protocols to perform sprint planning, coordinate development effort and integrate code bases. The study comprises 8 international companies in London, Bangalore and Delhi. Interviews with 46 practitioners were conducted between February 2010 and May 2012. A rigorous grounded theory research method was used to identify that scrum master teams comprise 10 activities: scrum of scrums facilitator, sprint planner, integration coordinator, learning coordinator, heart beat monitor, process anchor, task estimator, impediment remover, spike process coordinator and test coordinator. This systematic description of activities in scrum master teams extends our understanding of practitioner perspectives on agile process tailoring in large enterprises. Grounded theory is an emerging research method in software engineering.
An Approach To Naturalistic Evaluation

A naturalistic approach was used for the evaluation of a small-scale agricultural project in a village in Mali, West Africa. The illuminative evaluation strategy was tested for its ability to take into account those human aspects so often left out in the evaluation of development projects. Villager perceptions of the project form the basis of the evaluation. The evaluation consisted in (a) a period of observation, (b) discussion-interviews with informants according to age and gender (the comments from each group were compiled by themes into verbal images), (c) summarization and presentation of the images to relevant project and Malian administrators for their reactions, and (d) modified triangulation of the information through participant observa tion and secondary data. Conclusions concern villager participation and the management techniques used in the project. Conclusions about the illuminative strategy in the context of an international development project include its flexibility, which allows for progressive adaptation to the ever-changing situation of the project; the ability to represent different ideologies, beliefs, and opinions present in the project; the quality and richness of information about the reality of the project; and the absence of preordinate answer categories.
Analyses of vaccination protocols for Leptospira interrogans serovar autumnalis in hamsters.

Leptospirosis, caused by Leptospira spp. , is a zoonotic disease found worldwide. Killed whole cell leptospiral vaccines have been used as effective vaccines to elicit specific antibodies for protection. However, the involvement of cytokine responses after vaccination is not well characterized. Hamsters were immunized with killed L. interrogans serovar Autumnalis before challenge to study cytokine mRNA expression levels (interferon [IFN]-gamma, tumor necrosis factor [TNF]-alpha, interleukin [IL]-10, and IL-4). Vaccinated groups showed 92-100% survival rates, whereas control hamsters died within 6-10 days. However, live organisms were detected in vaccinated groups, and mild to moderate pathology was observed early in infection. IFN-gamma and TNF-alpha mRNA expression levels correlated with the severity of infection and lung pathology, whereas IL-4 and IL-10 expression levels were significantly higher in vaccinated groups. In summary, commonly used vaccines changed the cytokine profiles and protected hamsters from death but failed to stimulate sterile immunity and were unable to prevent the occurrence of pathology.
Measuring Narrative Engagement

Research indicates that the extent to which one becomes engaged, transported, or immersed in a narrative influences the narrative's potential to affect subsequent story-related attitudes and beliefs. Explaining narrative effects and understanding the mechanisms responsible depends on our ability to measure narrative engagement in a theoretically meaningful way. This article develops a scale for measuring narrative engagement that is based on a mental models approach to narrative processing. It distinguishes among four dimensions of experiential engagement in narratives: narrative understanding, attentional focus, emotional engagement, and narrative presence. The scale is developed and validated through exploratory and confirmatory factor analyses with data from viewers of feature film and television, in different viewing situations, and from two different countries. The scale's ability to predict enjoyment and story-consistent attitudes across different programs is presented. Implications for conceptualizing engagement with narratives as well as narrative persuasion and media effects are discussed.
Offering a Job: Meritocracy and Social Networks1

This study focuses on the impact of sex, race, and social networks, to analyze the hiring process in a midsized high‐technology organization, using information on all 35,229 applicants in a 10‐year period (1985–94). For gender, the process is entirely meritocratic: age and education account for all sex differences. But even without taking into account the two meritocratic variables, there are small if no differences between men and women at all stages in the hiring process. For ethnic minorities, the process is partly meritocratic but partly reliant upon social networks. Once referral method is taken into account, all race effects disappear. In hiring, ethnic minorities are thus disadvantaged in the processes that take place before the organization is contacted. They lack access to or utilize less well the social networks that lead to high success in getting hired.
Broadband RCS reduction of antenna with AMC

Planar periodic metallic arrays behave as artificial magnetic conductor (AMC) surfaces when placed on a grounded dielectric substrate and they introduce a zero degrees reflection phase shift to incident waves. A novel gradually concentric ring arrangement AMC (GCRA-AMC) applied to the broadband RCS reduction is presented. The simulated results show that the radiation performance of antennas is preserved when the GCRA-AMC is used. The RCS of the antenna with GCRA-AMC has been considerably reduced in a broadband.
Is Class Changing? A Work-Life History Perspective on the Salariat

Has the massive transformation of the class structure over the twentieth century changed the consequences of class? In particular, does the fact that the salariat has taken over from the manual working classes as the largest category mean that the implications of membership of the salariat for one's life chances is no longer the same? This paper takes retrospective life-history data from the British Household Panel Study and models patterns of change in the structure of work-life mobility between the ages of 25 and 35 for individuals born between 1900 and 1959. The purpose is to seek evidence of broad changes in the consequences of class, through the middle and late 20th century, using an extremely valuable data resource. The evidence suggests that there is cross-cohort change in the patterns of work-life mobility, both in terms of traditional class categories and in terms of the relationship between class and more general employment status categories, but more strongly in the latter case. In general, the pattern is one of declining immobility, including declining salariat retentiveness. The paper concludes with a consideration of what the data mean, and what this particular bounded analysis has to say about the question of change in the consequences of class.
The relationship of validity coefficients to the practical effectiveness of tests in selection: discussion and tables.

IT has often been pointed out that the magnitude of the correlation coefficient as such is not an adequate representation of the magnitude of the relationship between the two variables which are under consideration. A number of different statistical constants have been proposed by various persons, as giving a more satisfactory representation of the real magnitude of a relationship between two variables. All of these constants are relatively simple functions of the Pearson r. These include a class of functions of r which bear directly upon an evaluation of the extent to which one variable may be predicted from the other when the correlation coefficient is of a given magnitude. These functions of r include Kelly's alienation coefficient, k, which is \ A ~ **! ^such functions of k as Hull's measure of efficiency, E, which is 1-k, and Odell's g, which is k/\/2. All of these ways of evaluating the correlation coefficient have one fundamental characteristic in common, as might be expected from the fact that they are all closely related to the alienation coefficient. That is, that as the size of the correlation coefficient increases the extent to which one variable can be predicted from the other increases more and more rapidly. For example, an r of . 50 is usually considered to be only 13% as good as an r of 1.00. It is considered that an r of . 87 is only half as good as an r of 1.00. The wide-spread acceptance of such measures as the correct way of evaluating correlation coefficients has brought about a
Analyzing the Video Popularity Characteristics of Large-Scale User Generated Content Systems

User generated content (UGC), now with millions of video producers and consumers, is reshaping the way people watch video and TV. In particular, UGC sites are creating new viewing patterns and social interactions, empowering users to be more creative, and generating new business opportunities. Compared to traditional video-on-demand (VoD) systems, UGC services allow users to request videos from a potentially unlimited selection in an asynchronous fashion. To better understand the impact of UGC services, we have analyzed the world's largest UGC VoD system, YouTube, and a popular similar system in Korea, Daum Videos. In this paper, we first empirically show how UGC services are fundamentally different from traditional VoD services. We then analyze the intrinsic statistical properties of UGC popularity distributions and discuss opportunities to leverage the latent demand for niche videos (or the so-called "the Long Tail" potential), which is not reached today due to information filtering or other system scarcity distortions. Based on traces collected across multiple days, we study the popularity lifetime of UGC videos and the relationship between requests and video age. Finally, we measure the level of content aliasing and illegal content in the system and show the problems aliasing creates in ranking the video popularity accurately. The results presented in this paper are crucial to understanding UGC VoD systems and may have major commercial and technical implications for site administrators and content owners.
Oridonin Inhibits Tumor Growth and Metastasis through Anti-Angiogenesis by Blocking the Notch Signaling

While significant progress has been made in understanding the anti-inflammatory and anti-proliferative effects of the natural diterpenoid component Oridonin on tumor cells, little is known about its effect on tumor angiogenesis or metastasis and on the underlying molecular mechanisms. In this study, Oridonin significantly suppressed human umbilical vascular endothelial cells (HUVECs) proliferation, migration, and apillary-like structure formation in vitro. Using aortic ring assay and mouse corneal angiogenesis model, we found that Oridonin inhibited angiogenesis ex vivo and in vivo. In our animal experiments, Oridonin impeded tumor growth and metastasis. Immunohistochemistry analysis further revealed that the expression of CD31 and vWF protein in xenografts was remarkably decreased by the Oridonin. Furthermore, Oridonin reinforced endothelial cell-cell junction and impaired breast cancer cell transendothelial migration. Mechanistically, Oridonin not only down-regulated Jagged2 expression and Notch1 activity but also decreased the expression of their target genes. In conclusion, our results demonstrated an original role of Oridonin in inhibiting tumor angiogenesis and propose a mechanism. This study also provides new evidence supporting the central role of Notch in tumor angiogenesis and suggests that Oridonin could be a potential drug candidate for angiogenesis related diseases.
The Conscience of the Skin: Interwar Polish Autobiography and Social Rights

Between the World Wars, Polish sociologists gathered thousands of autobiographies by workers, peasants, and other "ordinary" people. The resulting body of "social memoir" can be read as an argument about social rights: authors simultaneously drew on Enlightenment ideas of subjecthood to press for enfranchisement and portrayed the limits of liberal citizenship, insisting on the embodied experience of poverty. While World War II heightened the urgency of life-writing in Poland (e.g. as testimony), however, postwar personal narratives came to be embedded in new, transnational rights discourses, through which they lost traction as arguments about specifically social rights.
