User communities and contents co‐ranking for user‐generated content quality evaluation in social networks

With the massive popularity of social networks, more and more users can produce millions of user‐generated contents (UGCs) daily. However, UGC quality is uneven, which has posed challenges to finding superior contents in such a large data set. In this paper, we present a new idea of UGC quality evaluation exploiting user communities, which are formed by users either in a friend circle or with similar interests in social networks. The intuition is that a user community can help evaluate the UGC quality better than a single user. Hence, we propose a new graph‐theoretic user communities and contents co‐ranking (UCCC) algorithm for UGC quality evaluation. UCCC evaluates UGCs and their related user communities simultaneously based on three different relationship networks: the network connecting UGCs, the network connecting user communities, and a third network that ties the two together. Contents and user communities are ranked following a co‐ranking algorithm based on the assumption that there is a mutually reinforcing relationship between them. Experiments using real‐world data have shown that UCCC outperforms competitive algorithms by a good margin in most cases and a user community is more useful than a single user for UGC quality evaluation.

Correlation between enzyme production, germ tube formation and susceptibility to fluconazole in Candida species isolated from patients with denture-related stomatitis and control individuals.

INTRODUCTION Phospholipase and proteinase secretion in yeasts of the genus Candida has been described as a relevant virulence factor. Also, germ tube formation by Candida albicans is associated with its invasive capacity and is considered an important pathogenic mechanism. METHODS To link the production of hydrolytic enzymes with the capacity to produce infection, 232 clinical isolates of yeasts from the oral cavity of 140 individuals wearing removable maxillary protheses were studied. The sample was composed of 70 patients with denture-related stomatitis (DRS) and 70 individuals with normal palatal mucosa. For strains identified as C. albicans, the correlation between germ tube formation and their capacity to cause infection was studied and the presence of Candida dubliniensis was investigated. Susceptibility to fluconazole was evaluated. RESULTS Candida albicans was the only species producing phospholipase and germ tube. We observed a higher level of production of phospholipase in cases of infection compared with commensals. Significant differences between the two groups of C. albicans isolates were observed as to germ tube production. Only, Candida glabrata showed lower susceptibility to fluconazole. CONCLUSION The results reinforced the idea that C. albicans is the most frequent and can be the most pathogenic yeast in oral candidosis. However, the strains isolated from DRS patients and healthy individuals showed the same virulence factors. It seems that several virulence attributes are involved in the infective process but no single factor contributes to Candida virulence. Candida dubliniensis was absent in the oral cavity of individuals with and without DRS.
ASPnP: An Accurate and Scalable Solution to the Perspective-n-Point Problem

SUMMARY We propose an accurate and scalable solution to the perspective-n -point problem, referred to as ASP n P. Our main idea is to estimate the orientation and position parameters by directly minimizing a properly deﬁned algebraic error. By using a novel quaternion representation of the rotation, our solution is immune to any parametrization degeneracy. To obtain the global optimum, we use the Gr¨obner basis technique to solve the polynomial system derived from the ﬁrst-order optimality condition. The main advantages of our proposed solution lie in accuracy and scalability. Extensive experiment results, with both synthetic and real data, demonstrate that our proposed solution has better accuracy than the state-of-the-art noniterative solutions. More importantly, by exploiting vectorization operations, the computational cost of our ASP n P solution is almost constant, independent of the number of point correspondences n in the wide range from 4 to 1000. In our experiment settings, the ASP n P solution takes about 4 milliseconds, thus best suited for real-time applications with a drastically varying number of 3D-to-2D point correspondences ∗ .
Maximum Tolerance and Maximum Greatest Tolerance - Weights and Threshold of Strict Separating Systems

An important consideration when applying neural networks is the sensitivity to weights and threshold in strict separating systems representing a linearly separable function. Two parameters have been introduced to measure the relative errors in weights and threshold of strict separating systems: the tolerance and the greatest tolerance. Given an arbitrary separating system we study which is the equivalent separating system that provides maximum tolerance or/and maximum greatest tolerance.

Consumer social responses to CSR initiatives versus corporate abilities

Purpose – Consumer responses to corporate social responsibility (CSR) initiatives when compared to consumer responses to corporate abilities (CA) have been elusory. Relevant empirical research on the subject shows unclear results. The objective of this research is to examine key antecedents to consumer social responses (CnSR), in particular, the comparative effects of CSR initiatives and CA in the consumer purchasing behavior.Design/methodology/approach – A choice‐based conjoint model was applied to quota consumer samples from two disparate countries (USA and Peru) in the shoe industry.Findings – The results demonstrate that some CSR initiatives, such as companies' environmental commitments, along with some CA, such as product quality, significantly explain the nature of consumer responses and a trade‐off effect on consumers' willingness to pay for a product. The differences between the two countries, and those expected for gender and age, strengthen the relationships tested.Practical implications – Impli.
A new processing method of infrared temperature images in copper electrolysis

In the copper electrolytic refining process, the short-circuit failure among the electrodes usually exists. When it occurs, the temperature distribution is often abnormal, accompanied by local or overall overheating. This paper proposes a novel processing method for infrared temperature images to effectively detect the short-circuit fault and locate the accurate malfunctioning spots. The design procedure contains contrast enhancement, filter denoising, edge detection, image segmentation, high temperature electrode positioning. Finally, experimental results show that the proposed method can guarantee real-time processing of the infrared image of the electrolytic cell and accurately mark the malfunctioning position of electrodes with high temperature fault.
A Study on the Temperature Dependence of the Ginzburg-Landau Parameter, Thermodynamic and Upper Critical Field of  ${\rm Nb}_{3}{\rm Sn}$ Strands

We report detailed magnetization measurement results for two internal-tin Nb3Sn strands. The paramagnetic background of a Mitsubishi strand is about 4 times larger than that of a KAT strand below the transition temperature, which can be understood as combined effects of Pauli and Langevin paramagnetism. From magnetic relaxation measurement for the KAT strand, a possibility of surface barrier effect is discussed. After subtracting the paramagnetic background, reversible magnetization data are analysed using the Hao-Clem model and the Ginzburg-Landau parameters (kappa), the thermodynamic and the upper critical fields (Bc,Bc2) at various temperatures are obtained. The temperature dependences of kappa, Bc and Bc2 are compared with the recent theoretical calculation results for Nb3Sn and also with widely used empirical formulas.
Predictive coding and the Bayesian brain: Intractability hurdles that are yet to be overcome

There is a growing body of evidence that the human brain may be organized according to principles of hierarchical predictive coding. A current conjecture in neuroscience is that a brain organized in this way can effectively and efficiently perform genuine Bayesian inferences. Given that many forms of cognition seem to be well characterized as Bayesian inferences, this conjecture has great import for cognitive science. It suggests that hierarchical predictive coding may provide a neurally plausible account of how forms of cognition that are modeled as Bayesian inference may be physically implemented in the brain. Yet, as we show in this paper, the jury is still out on whether or not the conjecture is really true. Specifically, we demonstrate that each key subcomputation invoked in hierarchical predictive coding potentially hides a computationally intractable problem. We identify ways in which computational modelers may or may not overcome these ‘intractability hurdles. ’
Non-rigid registration based on B-spline using point matching

This paper proposed a new method which can improve the efficiency and accuracy of non-rigid registration based on B-spline using point matching. The corner points of a reference image are extracted, and they find corresponding corner points of a target image using a measure which considers feature similarity between two corresponding corner points. Initial transfer vector and initial grid for B-spline is obtained using the one-to-one matched corner points. Finally, B-spline non-rigid registration process is performed with gradient descent optimization. As a result, we improved registration results, and time consumption.
Constructs in Strategic Management

Construct measurement is a cornerstone for research in any area. In the absence of information on the caliber of measurement practices within and across studies, it is extremely difficult to synthesize research and develop normative guidelines for managers. This Feature Topic aims to advance measurement practices by strategic management scholars. The Feature Topic includes six articles from a diverse array of perspectives. We describe the context of strategic management and measurement, examine how the Feature Topic articles address critical issues, and conclude with advice for authors and reviewers on this topic.
Entrepreneur Ability,Innovation Competence and Enterprise Performance

Human capital theory thinks that entrepreneurs are important resources of enterprises and an important contribution to the firm performance. This paper makes a research on the performance of small and medium-sized enterprises from the angle of the entrepreneurial ability. The relationship between the entrepreneur ability,innovation competence and firm performance are studied through a questionnaire survey,and theoretical assumptions about their relations are put forward. Results showed that:(1) entrepreneur ability of small and medium-sized enterprises is in significant positive correlation with firm performance;(2)there is significant positive correlation between innovation competence and firm performance;(3) there is significant positive correlation between enterprise innovation and firm competence. In addition,enterprise innovation plays an partial intermediary role in the effect of entrepreneurship on firm performance.
Automating the software development process

Much of the software development process is repetitive, tedious to perform, but possible to automate. Our SAGA Project research includes building models of software development tasks that accurately reflect the processes involved and have direct and efficient implementations. In this paper we assume the desirability of a software engineering environment that supports the entire life-cycle; automation should greatly enhance the quality and efficiency of software production and maintenance. To study the problems involved, SAGA has constructed ENCOMPASS, a prototype environment which supports software development. ENCOMPASS has provided valuable insights and experience; however, during its development and use many limitations have surfaced. In this paper we emphasize the configuration and project management aspects of our work. We discuss the current capabilities and limitations of ENCOMPASS, as well as describing the new systems being constructed to overcome its limitations and extend its life-cycle coverage.
A Novel DC Arc Fault Detection Method Based on Electromagnetic Radiation Signal

Because of lack of current zero, dc arc is hard to be extinguished, which has become the main reason causing faults in dc system. To find an effective method to detect dc arc faults is of great significance. In this paper, a method for detecting dc arc fault based on electromagnetic radiation signal is presented. A dc arc generating device is designed to simulate dc arc faults caused by loose connection in dc systems. A fourth-order Hilbert curve fractal antenna is adopted to detect the electromagnetic radiation signals of dc arc. The amplitude and spectrums of electromagnetic radiation signals measured under different circuit currents are analyzed. A photovoltaic (PV) system is constructed and the dc arc generated in that system is measured. The test results show that, under the present experimental condition, the electromagnetic radiation pulses have an obvious characteristic frequency, which are in a range of 39–41 MHz. The characteristic frequency of electromagnetic radiation of dc arc generated in PV system is around 39 MHz. Moreover, the characteristic frequency of dc arc is compared with that of switch operation. The dc arc has higher characteristic frequency and longer interval of each electromagnetic radiation pulse than those of the switch operation. The results indicate that the characteristic frequency of electromagnetic radiation signals can be used as the detection parameter of dc arc.
A Multiregion Assessment of Observed Changes in the Areal Extent of Temperature and Precipitation Extremes

AbstractThis study examines trends in the area affected by temperature and precipitation extremes across five large-scale regions using the climate extremes index (CEI) framework. Analyzing changes in temperature and precipitation extremes in terms of areal fraction provides information from a different perspective and can be useful for climate monitoring. Trends in five temperature and precipitation components are analyzed, calculated using a new method based on standard extreme indices. These indices, derived from daily meteorological station data, are obtained from two global land-based gridded extreme indices datasets. The four continental-scale regions of Europe, North America, Asia, and Australia are analyzed over the period from 1951 to 2010, where sufficient data coverage is available. These components are also computed for the entire Northern Hemisphere, providing the first CEI results at the hemispheric scale. Results show statistically significant increases in the percentage area experiencing m.
Assisted Reproductive Technologies: Toward Improving Implantation Rates and Reducing High-Order Multiple Gestations

Despite striking progress in reproductive medicine over the past quarter century, the number of high-order multiple gestations are unacceptably high, largely as a result of the drive to maintain pregnancy rates in a competitive range. Morphologic criteria are currently used to define the reproductive competence of individual embryos but are imperfect predictors of implantation potential. Current and potential strategies to improve the selection of embryos are described. By the use of several of these approaches, it is hoped that the overall number of embryos that are transferred will be reduced, thereby also reducing the multiple gestation rate. Target Audience: Obstetricians & Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader will be able to list and describe the more current assisted reproductive technologies, to describe the morphologic criteria used to define the reproductive competence of individual embryos, and to outline strategies to improve the selection of embryos.
Multiple Levels of Ethics Management: A Case of Airline and Hotel Firms

This paper purports a multi-level ethics management model by integrating and examining past theories in the literature. The model has five distinct levels, with progression occurring among the levels. The study verifies the existence of the five levels of the ethics management model within the hospitality and tourism context by performing a structured content analysis of corporate ethics disclosure of large global airline and hotel companies. The results support the thesis that practices related to the levels of ethics management exist. The airline cases demonstrate more similarity and are concentrated primarily in Level 4 (the progressive ethical organization), whereas the hotel cases illustrate a larger variance, ranging from Level 3 (the emergent ethical organization) to Level 5 (the ethical organization). The study extends research in the business ethics domain while providing a conceptual framework for capturing ethics practices in hospitality and tourism organizations.
NTBFsâ€™ growth modes in the context of the current global crisis. Do changes in sales mirror changes in employment?

Many studies have investigated firms? growth and its determinants. However, while studying how much firms grow, insufficient attention has been paid to how firms grow; namely to the different modes of growth that firms can and do choose. This paper contributes to the emerging literature on firms? modes of growth by examining the relationship between changes in sales and employment of New Technology-Based Firms (NTBFs) during the current global crisis. Our analysis originally adds to the received knowledge as prior investigations have implicitly assumed a positive growth scenario, in which firms increase their sales and may or may not increase their employees.
Generalized trace-back techniques for survivor memory management in the Viterbi algorithm

The trace-back technique is an effective approach for survivor memory management in the Viterbi algorithm. It is especially attractive when the number of states in the trellis is large, in which case the register exchange approach is impractical due to the area required for wiring. Previous descriptions of the trace-back technique have assumed either one or two trace-back pointers and have made specific assumptions about the speeds of those pointers. In this paper we present a general framework for implementing the trace-back technique with any number of trace-back pointers and with relaxed assumptions about the speeds of the pointers. We also show that the use of additional trace-back pointers reduces the memory requirements. Two implementations of the generalized trace-back techniques based on standard RAMs and custom shift registers are presented.
User interviews revisited: identifying user positions and system interpretations

Throughout the history of HCI, interviews have been utilized for collecting users' subjective evaluations of interactive technology. This paper raises the issue that these interviews are often deployed in a manner overlooking two aspects of evaluation: the relative positions from which the system is evaluated and the interviewees' interpretations of the system. In the study, 14 users of a new information system were asked to evaluate provocative claims about the system's usability. The analyses of their responses reveal two sources of variation: what is being evaluated and who is evaluating it. Interviewees evaluated the system's usability from five user positions: end user, supervisor, organization's representative, co-developer, and outsider. Also, four "faces" of the system were interpreted: UI, utility, communication medium, and unknown entity. These findings are employed for drawing of broader conclusions about the system and its use, and procedures for improving user interviews in HCI are presented.
Leishmania parasitophorous vacuoles interact continuously with the host cell's endoplasmic reticulum; parasitophorous vacuoles are hybrid compartments

Macrophages that express representative endoplasmic reticulum (ER) molecules tagged with green fluorescence protein were generated to assess the recruitment of ER molecules to Leishmania parasitophorous vacuoles (PVs). More than 90% of PVs harbouring Leishmania pifanoi or Leishmania donovani parasites recruited calnexin, to their PV membrane. An equivalent proportion of PVs also recruited the membrane‐associated soluble N‐ethylmaleimide‐sensitive factor attachment protein receptors (SNAREs), Sec22b. Both ER molecules appeared to be recruited very early in the formation of nascent PVs. Electron microscopy analysis of infected Sec22b/YFP expressing cells confirmed that Sec22b was recruited to Leishmania PVs. In contrast to PVs, it was found that no more than 20% of phagosomes that harboured Zymosan particles recruited calnexin or Sec22b to their limiting phagosomal membrane. The retrograde pathway that ricin employs to access the cell cytosol was exploited to gain further insight into ER–PV interactions. Ricin was delivered to PVs in infected cells incubated with ricin. Incubation of cells with brefeldin A blocked the transfer of ricin to PVs. This implied that molecules that traffic to the ER are transferred to PVs. Moreover the results show that PVs are hybrid compartments that are composed of both host ER and endocytic pathway components.
Occupancy and indoor environment quality sensing for smart buildings

This paper presents a technique to determine the occupancy and indoor environment quality (IEQ) in buildings by enhancing physical measurements from a distributed sensor network with a statistical estimation method. The research is motivated by the increasing demand for improving energy efficiency while maintaining healthy and comfortable environment in buildings. Features representing the occupancy level and the relative changes are extracted from a suite of sensors: passive infra-red (PIR) sensors, Carbon Dioxide (CO2) concentration sensors, and relative humidity (RH) sensors, which are networked and installed in a laboratory. An Autoregressive Hidden Markov Model (ARHMM) has been developed to model the occupancy pattern, based on the measurements, given its ability to establish correlations among the observed variables. The result is compared with that obtained from the classical Hidden Markov Model (HMM) and Support Vector Machines (SVM), which indicates that the ARHMM estimation method performed better than the other two methods, with an average estimation accuracy of 80.78%.
