Personalized Navigation and Random Walk on a Complex Heterogeneous Graph

As data in many disciplines continues to grow at a frantic pace, a more heterogeneous set of information sources both can and need to be connected in innovative ways to improve information search and recommendation systems. Using information retrieval (IR) as an example, classical search techniques are based on limited information, including query terms, the content of documents, and basic user characteristics. However, recent studies have started to investigate additional information resources, including semantic web data, knowledge graphs, linguistic features, user email account content, social networks, user behavior, the search context, and other sources. Intuitively, a heterogeneous graph integrating all these information sources could enhance search performance. However, the complexity of such graphs challenge most existing graph mining algorithms. In this study, we propose a novel approach for a personalized random walk over a complex heterogeneous graph; which we refer to as Personalized Graph Navigation (PGN). Unlike earlier expert-guided random walk approaches, by using an EM framework, PGN estimates the personalized usefulness probability distribution for each edge type (the latent variable), which can be used as a random walk navigation profile for a user on a heterogeneous graph. While PGN can cope with information retrieval/recommendation problems at a low cost, this method also transforms a complex heterogeneous graph into a homogeneous graph, allowing existing homogeneous graph mining algorithms to be applied to a heterogeneous graph.
A query language for selecting, harmonizing, and aggregating heterogeneous XML data

Purpose – The purpose of this paper is to introduce an expressive query language, called relational XML query language (RXQL), capable of dealing with heterogeneous Extensible Markup Language (XML) documents in data‐centric applications. In RXQL, data harmonization (i.e. the removal of heterogeneous factors from XML data) is integrated with typical data‐centric features (e.g. grouping, ordering, and aggregation). Design/methodology/approach – RXQL is based on the XML relation representation, developed in the authors' previous work. This is a novel approach to unambiguously represent semistructured data relationally, which makes it possible in RXQL to manipulate XML data in a tuple‐oriented way, while XML data are typically manipulated in a path‐oriented way.Findings – The user is able to describe the result of an RXQL query straightforwardly based on non‐XML syntax. The analysis of this description, through the mechanism developed in this paper, affords the automatic construction of the query result. This .
An Anatomy of Serial Acquirers, M&A Learning, and the Role of Post-Merger Integration

Using a global sample of 26,444 M&A transactions, we empirically investigate the main drivers of serial acquirer takeover performance, focusing on the benefits of organizational learning and the detriments of post-merger integration (PMI) problems. Taking single acquirers as a control group, we find that multiple deal makers exhibit a 0.4 percentage points lower short-term abnormal return, equal to a $31M shareholder value disadvantage. While learning through experience does not depend on the quantity of acquisitions, serial acquirers can gain proficiency in some specific types of deals (specialized learning hypothesis). When looking at the PMI process, the time between two consecutive transactions and relative deal size are key success factors, suggesting that the capacity of an organization to integrate is limited. This is strong support for the indigestion hypothesis.
iSimp: A sentence simplification system for biomedicail text

Text mining applications using natural language processing are often confronted with long and complicated sentences. This is observed particularly in the abstracts of scientific articles where authors summarize, in few sentences, the various facts described throughout the manuscript. Being rich in novel and important information, the abstract has been the primary target of biomedicai text mining applications. In this work, we aim to simplify complex sentences in abstracts of biomedicai text so that they can be readily processed by text mining applications. We focus on syntactic constructs that are frequently encountered in the biomedicai literature, such as coordinations, relative clauses, and appositions, with emphasis on their boundary detection. Our approach yielded good detection performance (average F-measure between 86.5% and 92.7%), and aided in improving biomedicai text mining applications, RLIMS-P and RankPref.
Critical Contextual Success Factors for Business Intelligence: A Delphi Study on Their Relevance, Variability, and Controllability

The present article investigates critical contextual success factors that influence business intelligence (BI) system success and design in organizations with regard to their relevance, variability, and controllability. The initial set of factors is based on an analysis of extant literature and serves as the basis for further research on this topic. In contrast to previous studies, a Delphi Study provides several advantages such as the validation of possible critical factors by domain experts and the multi-dimensional view on these factors. A carefully selected expert panel investigated the factors not only by means of relevance but also assessed each factor in terms of variability and controllability. This multi-dimensional approach allowed us to identify six distinct clusters of factors with similar attributes and, hence, similar implications for practice. This paper contributes to IS research on critical success factors and system design variables in general and gives specific insights into the BI domain. The results are expected to support BI managers addressing their challenges in BI initiatives and they also provide directions for future research.
Food Components and Dietary Patterns of Two Different Groups of Mexican Lactating Women

Objective: To evaluate the energy, nutrient intakes and dietary patterns of Mexican lactating women at one month postpartum, and the associations of maternal age and region on their intakes. Methods: A total of 60 women were studied: 41 from Northwest and 19 from Central Mexico, 33 adolescent and 27 adult women. Data were collected through two quantitative 24 h recalls. Two more recalls were used in a sub sample to calculate the coefficient of variation of intakes. Menus were based on the consumption frequency of foods. Results: The mean energy intake of the adolescent women (2354 ± 1199 kcal) and those of Central Mexico (1690 ± 981 kcal) was lower than the recommendations. Zinc, calcium, vitamin E, C and folate were inadequate (55 to 85% prevalence of inadequacy). Energy, dietary fiber, sodium, potassium, iron and folate intakes were higher (P < 0.05) in Northwest Mexico. Northwestern women consumed less variety of vegetables or fruits compared to Mexico City region women. Wheat tortillas and beans were from Northwestern but not from the Mexico City region diet. Conclusions: The energy and nutrient intakes of women were different by regional hospital and not by age. Education about the importance of the maternal diet during lactation should be directed toward increasing consumption of foods rich in micronutrients.
Performance Verification of a Multimodal Interferometric DOA-Estimation Antenna

In our previous letter, a novel method of estimating the direction of arrival (DOA) of received signals was introduced. The method combines interferometry and multimodal principles to find the DOA in both elevation and azimuth. We also presented a new wideband waveguide-fed DOA-estimation (DOAE) antenna based on the new method. That antenna is simpler in its hardware than an earlier DOA-antenna published in 1957, and it has an added capability of DOAE in elevation. This letter describes a direction-finding (DF) test antenna that was designed, fabricated, and measured in order to verify the new DOAE method. The antenna's measured results indeed validate the new DOAE method. Both azimuth and elevation DOAs of received signals were extracted correctly. As in our previous letter, the system herein consists of two subantennas positioned one above the other. The first is a biconical horn antenna feeding a thick coaxial-waveguide loaded by four feed-probes. The probes are connected to a printed RF-combiner comprising two output ports corresponding to ±1-order circular phase modes (CPMs). The second antenna is a vertical dipole outputting a signal that serves as a reference for interferometry in elevation, as well as a reference zero-order CPM for azimuth estimation.
When Are Leaders Receptive to Voiced Creative Ideas? Joint Effects of Leaders’ Achievement Goals and Personal Sense of Power

Voiced suggestions for improvement and constructive change (i.e., voiced creative ideas) by employees are important for organizations. In order to reap the benefits of these ideas, leaders need to be receptive. Drawing on achievement goal theory and approach-inhibition theory of power, we examined the joint effects of leader achievement goals and personal sense of power on leader receptivity to voiced creative ideas in two studies. In a field study (Study 1, N = 136), we found that leaders pursuing mastery-approach goals were positively related to leader receptivity. Receptivity for leaders pursuing performance-approach goals was found to be contingent upon their personal sense of power, with a positive (negative) association under conditions of high (low) sense of power. Similarly, in experimental study (Study 2, N = 93), in which we manipulated leader achievement goals, the receptivity of performance-approach goal leaders was contingent upon their sense of power. When sense of personal power was high, performance-approach goal leaders displayed higher levels of receptivity than when their personal sense of power was low. An implication is that personal sense of power may prevent leaders with performance-approach goals from disregarding creative ideas that are put forward by their subordinates. These findings extend insight into how and when leaders are receptive to voiced creative ideas.
Hot-swap parallel operation of boost converters designed for the output of fuel cells

A control method for parallel connected, hot- swappable boost converters suitable to use with fuel cells is described. Simulation results for the system are included. The simulation study has been carried out in MATLAB-SIMULINK. The dynamic model of the fuel cell is also included in the simulations. The control algorithm used in the design adjusts the number of units to operate in parallel depending on the total load. Current and power sharing is achieved by measuring the input current of the converters. This method is compared with others for the same function. Dynamic equivalent circuit of the fuel cell is included in the simulations to evaluate the effects of current ripples. Finally, parallel connection design is compared with a single-unit design in terms of efficiency and costs.
Specificity in Transmembrane Helix-Helix Interactions Mediated by Aromatic Residues*

Aromatic residues have been previously shown to mediate the self-assembly of different soluble proteins through π-π interactions (McGaughey, G. B., Gagne, M., and Rappe, A. K. (1998) J. Biol. Chem. 273, 15458–15463). However, their role in transmembrane (TM) assembly is not yet clear. In this study, we performed statistical analysis of the frequency of occurrence of aromatic pairs in a bacterial TM data base that provided an initial indication that the appearance of a specific aromatic pattern, Aromatic-XX-Aromatic, is not coincidental, similar to the well characterized QXXS motif. The QXXS motif was previously shown to be both critical and sufficient for stabilizing TM self-assembly. Using the ToxR system, we monitored the dimerization propensities of TM domains that contain mutations of interacting residues to aromatic amino acids and demonstrated that aromatic residues can adequately stabilize self-association. Importantly, we have provided an example of a natural TM domain, the cholera toxin secretion protein EpsM, whose TM self-assembly is mediated by an aromatic motif (WXXW). This is, in fact, the first evidence that aromatic residues are involved in the dimerization of a wild type TM domain. The association mediated by aromatic residues was found to be sensitive to the TM sequence, suggesting that aromatic residue motifs can provide a general means for specificity in TM assembly. Molecular dynamics provided a structural explanation for this backbone sequence sensitivity.
Interference Effects in the Picture-Word Stroop Task

Line drawings of common objects with an embedded three-or four-letter word or scrambled word were presented either to the right or left visual field. Subjects were to name the line drawing of a common object as fast and as accurately as possible. Reaction times and response accuracy were recorded and analyzed. Percent errors were significantly higher when a line drawing with a word was presented in the right visual field than in the left visual field. Sex of subject was not significant. This finding is analogous to results found when the color-word Stroop task is used.

An efficient SAGE-based data detection algorithm for OFDM systems in the presence of very fast fading channels

In this paper, an iterative and computationally efficient data detection algorithm is proposed based on the space alternating generalized expectation maximization (SAGE) technique for orthogonal division multiplexing (OFDM) systems under fast fading channels. The proposed detector includes the original detector presented in [1] as one of its special cases. With a proper choice of its parameters, simulations show that the new detector has negligible performance loss than original one in [1] with smaller number of iterations.
Social Media and its Implications for Marketing Communications

The field of marketing communications studies is often called on to close the gap between marketing and computer-mediated studies. This chapter engages with the concept of social media in the design and implementation of marketing communication programmes, particularly in the UK Fashion sector. The chapter goes on to conclude, rather sceptically, that understandings of the various nuances of social media platforms could engender effective customer retention programmes. It also offers a new way of thinking about customer engagement, incorporating social media platforms. INTRODUCTION AND CONTEXT In recent years, social media has emerged as a topic of great interest to scholars and practitioners alike (see for example Hennig-Thurau et al., 2010; Hoffman & Novak, 2011; Kaplan & Haenlein, 2010). The tremendous success of social media has been witnessed in terms of adoption and usage, caused by a paradigm shift in the way people communicate, express ideas and thoughts, and even how they interact with companies (Kaplan & Haenlein, 2010; Mangold & Faulds, 2009; Palmer & Koenig-Lewis, 2009). Traditionally, enterprises maintained control over relationship activities while customers were passive “receivers” (Christodoulides et al., 2011; Hennig-Thurau et al., 2010; Jahn & Kunz, 2012). Web 2.0 technologies have transferred power over brands directly to consumers, turning them into empowered, educated, technology-savvy and informed customers (Constantinides & Fountain, 2008; Constantinides, 2008). Thus, they have placed the consumer in the ‘driving seat’ and forced managers to concentrate their efforts on managing the dialogue, not the customer (Baird & Parasnis, 2011b). More importantly, the cultural shift in the Irina Yankova London Metropolitan University, UK Wilson Ozuem University of Gloucestershire, UK DOI: 10.4018/978-1-4666-6595-8.ch011
The sequence of 36·8 kb from the left arm of chromosome XIV reveals 24 complete open reading frames: 18 correspond to new genes, one of which encodes a protein similar to the human myotonic dystrophy kinase

We have determined the complete nucleotide sequence of a 36·8 kb segment from the left arm of chromosome XIV carried by the cosmid 14–11. The sequence encodes the 5′ coding region of the PSD1 gene, the 3′ coding region of an unknown gene and 24 complete open reading frames, of which 18 correspond to new genes and six (SKO1, SCL41A, YGP1, YCK2, RPC31 and MFA2) have been sequenced previously. Of the 24 new genes, five show significant similarities to sequences present in the databanks. These include elongation factors 2 and the human myotonic dystrophy kinase. The sequence has been deposited in the EMBL databank under the Accession Number X92517.
Analysis of development levels in the cities of Tehran province regarding health infrastructural index: the strategy of standardized score and Morris’ inequality index

Background: One of the main indexes of development is health index or the degree to which a society enjoys health and therapeutic services. The present study was done with the aim to analyze development levels in cities in Tehran regarding health infrastructural index using the standardized score and Morris’ model. Methods: This is a descriptive and pragmatic study which ranks 14 cities in Tehran province using the standardized score and Morris’ models based on 10 selected health indexes. The required data were gathered using a researcher-made information list and the information gathered from the Statistics Center and Tehran University of Medical Sciences. The data were analyzed using Excel software. Results: The development coefficient in the studied cities varies from 0.595 to -0.379 so that Rey city has the highest level of development and Pishva city has the lowest level of development among the studied cities. The more number of the cities (43%) was among the rather undeveloped group and none of the cities (0%) was in the rather developed group. Conclusion: Regarding the findings, there is a big gap and difference regarding enjoying health and therapeutic infrastructural indexes among the cities in Tehran province. Therefore, it is suggested that development-oriented plans consistentent with development levels should be implemented in these cities.
Health status monitor of aerospace payload based on neural network and fuzzy classification

Aerospace payload experiences integration, testing, storage, transportation, launch and on-orbit operation during its life cycle. Because of its long-life cycle, it should be ensured with a long-term stable operation during the period. Compared to the application equipment on the ground, on-orbit payload is more difficult to get timely maintenance. Since on-orbit payload cannot be manually checked, we can only identify its status through the test point data and observation point data. In this paper, a method of monitoring the health status of on-orbit payload based on fuzzy classification and neural network is proposed to insure the stability of long-term orbit equipment. We choose the test point data and observation point data returned from the payload as the input, and the status of on-orbit payload as the output. The fuzzy neural network is used to assess the health status of the payload in its life span: the normal state, the performance degradation state, or the functional failure state. When aerospace payload is in the performance degradation state, was assess the degree of degradation of the system performance, and grasp the health status information of on-orbit payload. The health status monitor makes PHM (Prognostics and Health Management) more intelligent, so that the system failures can get early diagnosis, prevention and treatment. It can also reduce the cost of payload maintenance, and increase the length of life of on-orbit payload.
AR-glasses-based attention guiding for complex environments: requirements, classification and evaluation

Augmented Reality (AR) based assistance has a huge potential in the context of Industry 4.0: AR links digital information to physical objects and processes in a mobile and, in the case of AR glasses, hands-free way. In most companies, order-picking is still done using paper lists. With the rapid development of AR hardware during the last years, the interest in digitizing picking processes using AR rises. AR-based guiding for picking tasks can reduce the time needed for visual search and reduce errors, such as wrongly picked items or false placements. Choosing the best guiding technique is a non-trivial task: Different environments bring their own inherent constraints and requirements. In the literature, many kinds of guiding techniques were proposed, but the majority of techniques were only compared to non-AR picking assistance. To reveal advantages and disadvantages of AR-based guiding techniques, the contribution of this paper is three-fold: First, an analysis of tasks and environments reveals requirements and constraints on attention guiding techniques which are condensed to a taxonomy of attention guiding techniques. Second, guiding techniques covering a range of approaches from the literature are evaluated in a large-scale picking environment with a focus on task performance and on factors as the users' feeling of autonomy and ergonomics. Finally, a 3D path-based guiding technique supporting multiple goals simultaneously in complex environments is proposed.
Transcriptional and posttranscriptional regulation of the rat prolactin gene by calcium

The rat prolactin gene is expressed at a high basal level in the pituitary tumor GH3 cell line. Culturing GH3 cells in a low-Ca2+, serum-free medium (SFM) depresses prolactin mRNA levels, and subsequent addition of Ca2+ to the SFM results in a specific, gradual, and sustained increase in prolactin mRNA levels. We have now examined whether the observed increase in prolactin mRNA levels can be attributed solely to an increase in the transcriptional rate of the prolactin gene. Treatment of GH3 cells in SFM with 0.4 mM CaCl2 for 24 to 48 h increased cytoplasmic prolactin mRNA levels by 5- to 10-fold, whereas the transcriptional rate of the prolactin gene was increased by less than twofold over values for SFM controls. Prolactin mRNA levels increased progressively during the 24-h period after Ca2+ addition, whereas prolactin gene transcription never exceeded a twofold increase over values for SFM controls. The activities of nuclear extracts from control and Ca2(+)-induced cells were examined in an in vitro transcription assay. The two extracts directed transcription from the prolactin promoter and the adenovirus major late promoter equally well. Cycloheximide had no effect on the ability of Ca2+ to increase or maintain prolactin mRNA levels. In dactinomycin mRNA clearance experiments, prolactin mRNA was cleared at the same rate in the absence and presence of Ca2+. These results demonstrate that although Ca2+ has a small effect on the transcriptional rate of the prolactin gene, Ca2+ produces a significant increase in prolactin mRNA levels by acting at a posttranscriptional site(s). Furthermore, Ca(2+) appears to increase prolactin mRNA levels by posttranslational modification of a stable protein, probably at a nuclear site.
