Optimizing enterprise search by automatically relating user context to textual document content

It is widely agreed that information retrieval (IR) systems benefit enormously from considering not only the user's query but also contextual data. In enterprise IR systems corporate knowledge bases and additional manually triggered information about users are normally taken to obtain such contextual data. In this paper we propose a solution for role-specific search in enterprise environments without the need of manual administration of mappings between roles and documents. We include collaboratively constructed knowledge engineering systems for computing similarity measures between user role attributes and relevant information snippets in enterprise documents. Our approach suggestsoptimizing such enterprise search systems by a role-sensitive ranking algorithm that relates contextually-derived information needs of users to unstructured (textual) data in documents. Hence we introduce a linguistic conceptfor generatingrole describing word vectorsbased on query (search) histories and corporate knowledge base generation. The Introduction outlines some basic ideas concerning the major areas of enterprise search, some relevant differences between web search and enterprise search. Subsequently we sketch our optimized enterprise search model. In Chapter 2some theoretical background and Related Work is briefly discussed.Chapter 3depicts some linguistically relevant details of our proposed model. We discuss our concept of User Roles, Role Term Vectors, some approaches for Role Term Extraction andTerm Extraction incorporating knowledge bases and query histories. In Chapter4 we describe our ranking mechanism, the re-ranking strategy and the method for Role Relevance Scoring. Chapter 5 gives a conclusion of the work as well as an outlook on future work.
Moving beyond homophobia, harassment and intolerance: gay male university students’ alternative narratives

This paper draws on a small-scale qualitative study of the lived experiences of gay male students in their final year of undergraduate study at a UK university. In contrast to the narratives almost universally reported in academic literature, anti-gay victimisation and harassment were not experienced or framed as dominant discourses in the stories of the six participants. I discuss how despite heterosexuality being the assumed, expected and compulsory discourse at university, the participants made positive sense of their experiences, and how through careful negotiation they were able to address, explore and engage with their (homo)sexual identities and orientation. I challenge the common and (mostly) unquestioned practices of defining gay students solely on the basis of their negative accounts of their experiences, labelling them all as victims, and locating the entire population within a pathologised framework. Instead I advocate a nuanced and balanced perspective which acknowledges the alternate and non-victimised accounts of gay students to provide a more inclusive, comprehensive, fuller and richer understanding of their lived experiences at university.
Effects of Acute Alcohol Intoxication on Empathic Neural Responses for Pain

The questions whether and how empathy for pain can be modulated by acute alcohol intoxication in the non-dependent population remain unanswered. To address these questions, a double-blind, placebo-controlled, within-subject study design was adopted in this study, in which healthy social drinkers were asked to complete a pain-judgment task using pictures depicting others' body parts in painful or non-painful situations during fMRI scanning, either under the influence of alcohol intoxication or placebo conditions. Empathic neural activity for pain was reduced by alcohol intoxication only in the dorsal anterior cingulate cortex (dACC). More interestingly, we observed that empathic neural activity for pain in the right anterior insula (rAI) was significantly correlated with trait empathy only after alcohol intoxication, along with impaired functional connectivity between the rAI and the fronto-parietal attention network. Our results reveal that alcohol intoxication not only inhibits empathic neural responses for pain but also leads to trait empathy inflation, possibly via impaired top-down attentional control. These findings help to explain the neural mechanism underlying alcohol-related social problems.
Contradiction and Sensemaking in Acquisition Integration

The authors draw on research on acquisitions and on newcomer adjustment to analyze acquired managers’ sensemaking experiences. They pursue three interrelated objectives: how acquired managers, as newcomers, make sense of role changes; how these managers’ frames contrast with new frames encountered at the acquirer; how relationships with acquiring managers influence adjustment to new roles and frames. The authors report on a study of three acquisitions of small firms by a large, bureaucratic, serial acquirer. Findings showed contraction of the managerial role—and the resulting reconfigured role identity—created tensions emanating from managing familiar situations under new frames. Relationships with acquiring managers—a potential source of informational, material, political, and social resources—played a role in mitigating or amplifying the challenges experienced. Comparison of acquired and acquiring managers’ frames showed that absorption of small firms by large, serial acquirers creates in organizations heterogeneous sensemaking spaces characterized by contradiction.
‘Poisonous, Filthy, Loathsome, Damnable Stuff’: The Rhetorical Ecology of Vaccination Concern

In this article, we analyze newspaper articles and advertisements mentioning vaccination from 1915 to 1922 and refer to historical studies of vaccination practices and attitudes in the early 20th century in order to assess historical continuities and discontinuities in vaccination concern. In the Progressive Era period, there were a number of themes or features that resonated with contemporary issues and circumstances: 1) fears of vaccine contamination; 2) distrust of medical professionals; 3) resistance to compulsory vaccination; and 4) the local nature of vaccination concern. Such observations help scholars and practitioners understand vaccine skepticism as longstanding, locally situated, and linked to the sociocultural contexts in which vaccination occurs and is mandated for particular segments of the population. A rhetorical approach offers a way to understand how discourses are engaged and mobilized for particular purposes in historical contexts. Historically situating vaccine hesitancy and addressing its articulation with a particular rhetorical ecology offers scholars and practitioners a robust understanding of vaccination concerns that can, and should, influence current approaches to vaccination skepticism.
Modeling Impacts of Alternative Practices on Net Global Warming Potential and Greenhouse Gas Intensity from Rice–Wheat Annual Rotation in China

Background Evaluating the net exchange of greenhouse gas (GHG) emissions in conjunction with soil carbon sequestration may give a comprehensive insight on the role of agricultural production in global warming. Materials and Methods Measured data of methane (CH4) and nitrous oxide (N2O) were utilized to test the applicability of the Denitrification and Decomposition (DNDC) model to a winter wheat – single rice rotation system in southern China. Six alternative scenarios were simulated against the baseline scenario to evaluate their long-term (45-year) impacts on net global warming potential (GWP) and greenhouse gas intensity (GHGI). Principal Results The simulated cumulative CH4 emissions fell within the statistical deviation ranges of the field data, with the exception of N2O emissions during rice-growing season and both gases from the control treatment. Sensitivity tests showed that both CH4 and N2O emissions were significantly affected by changes in both environmental factors and management practices. Compared with the baseline scenario, the long-term simulation had the following results: (1) high straw return and manure amendment scenarios greatly increased CH4 emissions, while other scenarios had similar CH4 emissions, (2) high inorganic N fertilizer increased N2O emissions while manure amendment and reduced inorganic N fertilizer scenarios decreased N2O emissions, (3) the mean annual soil organic carbon sequestration rates (SOCSR) under manure amendment, high straw return, and no-tillage scenarios averaged 0.20 t C ha−1 yr−1, being greater than other scenarios, and (4) the reduced inorganic N fertilizer scenario produced the least N loss from the system, while all the scenarios produced comparable grain yields. Conclusions In terms of net GWP and GHGI for the comprehensive assessment of climate change and crop production, reduced inorganic N fertilizer scenario followed by no-tillage scenario would be advocated for this specified cropping system.
Reasoning about Contextual Equivalence: From Untyped to Polymorphically Typed Calculi

This paper describes a syntactical method for contextual equivalence in polymorphically typed lambda-calculi. Our specific calculus has letrec as cyclic let, data constructors, case-expressions, seq, and recursive types. The typed language is a subset of the untyped language. Normal-order reduction is defined for the untyped language. Since there are less typed contexts the typed contextual preorder and equivalence are coarser than the untyped ones. We use type-labels for all subexpressions of the typed expressions, and prove a context lemma for the type-labeled calculus. We show how to reason about correctness of program transformations in the typed language, and how to easily transfer the methods and results from untyped program calculi to polymorphically typed ones.
Structure of the nucleoid in cells of Streptococcus faecalis

The structure of the nucleoid of Streptococcus faecalis (ATCC 9790) was examined and compared in the unfixed and fixed states by immersive refractometry and electron microscopy. It appears from these studies that the nucleoid structure is much more centralized in unfixed chloramphenicol-treated (stationary-phase) cells than it is in cells in the exponential phase of growth. The more dispersed configuration of the exponential-phase nucleoid could be preserved by fixation in glutaraldehyde, but not in Formalin or in osmium tetroxide. One important factor in explaining these differences in preservation is that glutaraldehyde (but not Formalin or osmium tetroxide) can rapidly cross-link the amino groups of macromolecules in cells. It was also observed that osmium tetroxide resulted in a preferential breakdown of nascent ribonucleic acid. These results are interpreted as indicating that glutaraldehyde is able to stabilize the exponential-phase nucleoid before it assumes the more central appearance seen in osmium tetroxide- and Formalin-fixed cells. These results are discussed in terms of the proposed organization of the exponential-phase nucleoid in unfixed cells.
The Intersection of Race and Class in the South African University: Student Experiences.

The purpose of this article is to make a contribution to the discussion on the sociological features of higher education and the significant ways in which it comes to produce a particular version of the racial experience.2 While work has appeared which has begun to comment on fragmentation of identity in South African higher education there is insufficient attention paid to the ways in which identity-making takes place. What this article will do is to focus on the racial as a resource which is brought into contact with the institution and to suggest what the outlines of this coming together are in the South African setting. It does not, indeed cannot, develop a deep discussion, as in the classic identity-formation literature, about subject formation – who, for example, is attributing what to whom and under what power conditions. What it seeks to do, in a limited way, is point to interesting new trends in how race is being experienced by South African students and particularly by black students. What does the racial experience look like for them? When students invoke race what is it that they are talking about? South African Journal of Higher Education Vol. 22 (3) 2008: pp. 662-678
Neuropsychologica Principia Brevita: An Application to Traumatic (Acquired) Brain Injury

The concepts and discoveries of modern neuroscience now challenge many of the presumptions that influence diagnostic decisions within neurology, psychiatry, and clinical neuropsychology. Many of these presumptions are derived from archaic bivariate models such as the mind-body argument, organic-functional dichotomy, and single lesion-single behavior causality. Thirteen basic principles which may be useful for inferring more reliable and accurate relationships between microstructural function and clinical manifestations are developed.
Elevated Serum Concentration of Chitinase 3-Like 1 is an Independent Prognostic Biomarker for Poor Survival in Lung Cancer Patients

Background/Aims: The chitinase 3-like 1 (CHI3L1) has an important role in cancer progression, and high CHI3L1 expression is associated with the development and progression of cancers. Previous studies had been controversial with respect to the association between CHI3L1 expression and lung cancer prognosis. Thus, we performed a meta-analysis to investigate the prognostic value of CHI3L1 expression in lung cancer. Methods: We searched Pubmed, Embase, and Wanfang databases to identify eligible studies. Overall survival and disease free survival were collected from included studies. Pooled hazard ratios (HRs) with 95% confidence interval (95%CI) were calculated to estimate the association. Seven studies comprising 911 lung cancer patients were included in this meta-analysis. Results: The results showed high CHI3L1 expression was independently associated with poorer overall survival in lung cancer patients (HR = 1.71, 95%CI 1.24-2.37, P = 0.001). Subgroup analysis by histological type showed that high CHI3L1 expression was independently associated with poorer overall survival in both non small-cell lung cancer patients (HR = 2.23,95%CI 1.43-3.47, P < 0.001) and small-cell lung cancer patients (HR = 1.45, 95%CI 1.06-2.00, P = 0.021). In addition, sensitivity analysis by omitting single study by turns did not change the pooled outcomes obviously. Conclusion: Our results suggest that elevated serum CHI3L1 concentration is an independent prognostic biomarker for poorer survival in lung cancer patients.
Constrained Stochastic Gradient Descent: The Good Practice

Stochastic Gradient Descent (SGD) is the method of choice for large scale problems, most notably in deep learning. Recent studies target improving convergence and speed of the SGD algorithm. In this paper, we equip the SGD algorithm and its advanced versions with an intriguing feature, namely handling constrained problems. Constraints such as orthogonality are pervasive in learning theory. Nevertheless and to some extent surprising, constrained SGD algorithms are rarely studied. Our proposal makes use of Riemannian geometry and accelerated optimization techniques to deliver efficient and constrained-aware SGD methods.We will assess and contrast our proposed approaches in a wide range of problems including incremental dimensionality reduction, karcher mean and deep metric learning.
Correlative Analysis of Data and Functions of Neuronal Synapse

Until recently, the synaptic transmission and excitatory amino acid transporters activation of neurons are very well discussed in the previous studies and are considered to be the two distinct features of Synapse. It is also found that a large number of interactions take place in the domain of ionic exchanges and protein interactions in synapses. It is evolutionary to have destined to release of Neurotransmitters to conduct an impulse to the other consecutive neurons, which forms the most important characteristic of synapse. From the popular perspective, it has been identified that detailed theoretical closer correlation of data produced through various studies about synapse can unravel many mysteries related to functions of synapse. Hence, this research paper tries to concentrate on a selected group of prominent characteristics and properties of synapse and also highlights some noteworthy discoveries, emphasizing the influential capabilities of them in the thought process and improving the knowledge of the field. It also highlights the expressive properties and forms of synapse brought out through the evidences available in sparse to dense data in a correlational way.
Formyl-Modified Polyaniline for the Catalytic Dehydration of Fructose to 5-Hydroxymethylfurfural.

We report an unprecedented solid organic-base catalyst, formyl-modified polyaniline (FS-PAN), for the dehydration of fructose to 5-hydroxymethylfurfural (HMF) with a high yield of 90.4 mol %. We demonstrate that the nitrogen atoms incorporated between the phenyl rings in the backbone of the polyaniline chain contribute to the basicity of the catalyst. The grafting of electron-withdrawing formyl groups to the imine nitrogen atoms leads to a significant increase of basicity of the polymer catalyst owing to the greater localization of electrons at the amide nitrogen atom formed. A linear dependence of the yield of HMF on the grafting level of formyl groups in FS-PAN indicates that the amide acts as the active phase. A possible reaction mechanism for this organic-base-catalyzed dehydration reaction is proposed. The side-reaction of HMF rehydration is inhibited thoroughly, and the condensation of any reaction intermediates to undesirable oligomers is restrained by this base catalyst. This organic-base catalyst can be recycled completely without loss of activity. This research highlights the first application of a highly effective and stable solid base catalyst for the transformation of renewable carbohydrates into fine chemicals.
Broadening the Concept of Expectations in Public Relations

Expectations have been connected to many central concepts of public relations research, yet definitions of what is meant by expectations are lacking. This article aims to broaden the understanding of expectations by taking into account their multidimensional nature, suggesting that there are several explanations to expectations depending on what the expectation is based on. We suggest that, in organizational context, expectations are two-fold assessments of what is considered good or desirable (expectation tone ranging from positive to negative) and the confidence placed in the organization (organization-specific context ranging from high to low confidence). As a result of the conceptual review with theoretical input from areas outside the scope of public relations, the article presents the Expectation Grid, where expectations are acknowledged as continuums of tone and context.
LIU: Localization via Fusion of IMU and Ultrasonic Positioning

For indoor positioning scenarios, the advantage of IMU (Inertial Measurement Unit) based method lies on its high positioning information refresh rate and the strong ability of anti-interference. However, due to the procedure of recursive integral, the cumulative positioning error of IMU positioning grows over time and will diverge in the long run. Due to the high time resolution, the accuracy of ultrasonic positioning is extremely high, and the measured location information is independent of each other. But limited by the physical properties, the updating frequency of ultrasound positioning is low as compared to IMU positioning and it is easy to produce wild value. To achieve the complementary advantages of the above mentioned methods, we propose a fusion localization approach which is based on IMU and augmented with ultrasonic sensors. The EKF (Extended Kalman Filter) is adapted for position estimation and the innovation filter is added into EKF in order to remove the wild value of measurement. The IMU location data is corrected with the fused error information, and so as to achieve the fusion positioning. The simulation shows that compared with the single measurement positioning, our fusion method can ensure not only the positioning accuracy but also the stability and anti-interference of the localization.
A Test Matrix Collection for Non-Hermitian Eigenvalue Problems

The primary purpose of this collection is to provide a testbed for the development of numerical algorithms for solving nonsymmetric eigenvalue problems. In addition, as with many other existing collections of test matrices, our goal includes providing an easy access to \practical" eigenproblems for researchers, educators and students in the community who are interested in the origins of large scale nonsymmetric eigenvalue problems, and in the development and testing of numerical algorithms for solving challenging non-Hermitian eigenvalue problems in real applications. In this document, we describe the mechanism for obtaining a copy of the matrices and for using the collection. All test matrices currently included in the collection are documented in Appendices.
Entrepreneurship as Elixir and Mutagen

Metaphors are powerful tools for sensemaking, sensegiving, and theory development, but they are often concealed in academic writing. This paper uncovers two metaphors underlying entrepreneurship discourse and research—elixir and mutagen. The elixir metaphor is uncovered by examining critiques of entrepreneurship research, and serves as a compact description of problematic aspects entrepreneurship scholars should be mindful of. The mutagen metaphor is uncovered by examining evolutionary frameworks, focusing on the role entrepreneurship plays in them. The paper illustrates how the mutagen metaphor can be used to reframe entrepreneurship, and uses the metaphors to interest, inform, and provoke.
The roles of the DAZ family in spermatogenesis

The DAZ family of genes are important fertility factors in animals, including humans. The family consists of Y-linked DAZ, and autosomal homologs Boule and Dazl. All three genes encode RNA-binding proteins that are nearly exclusively expressed in germ cells. The DAZ family is highly conserved, with ancestral Boule present in sea anemones through humans, Dazl conserved among vertebrates, and DAZ present only in higher primates. Here we review studies on DAZ family genes from multiple organisms, and summarize the common features of each DAZ gene and their roles during spermatogenesis in animals. DAZ family proteins are thought to activate the translation of RNA targets, but recent work has uncovered additional functions. Boule, Dazl, and DAZ likely function through similar mechanisms, and we present known functions of the DAZ family in spermatogenesis, and discuss possible mechanisms in addition to translation activation.
