Managing customer information and knowledge with social media in business-to-business companies

The recent innovation literature has increasingly emphasized the efficient use of knowledge and information not only inside the company borders, but particularly the knowledge locating outside the company borders, such as the knowledge of customers and users. In addition, the co-creation of new knowledge has gained fast in importance. Various types of collaborative web tools and approaches, such as social media, can enable and significantly increase the collaboration, the collaborative knowledge creation and the use of the distributed knowledge both within and outside the company borders. In this paper, we have studied the role and possibilities of social media in the sharing and creation of customer information and knowledge especially from the perspective of business-to-business companies' innovation with an extensive literature review. Business-to-business context was chosen because it is in many ways a very different environment for social media than business-to-consumer context, and is currently very little academically studied.
Factors Associated with Bacterial Vaginosis among Women Who Have Sex with Women: A Systematic Review

Background Women who have sex with women (WSW) have a higher burden of bacterial vaginosis (BV) than heterosexual women; studies of risk factors specific to this population are limited. We summarised current knowledge regarding risk factors for BV among WSW by systematic review. Methods This systematic review was conducted according to the PRISMA statement. PUBMED, EMBASE, Web of Science and The Cochrane Library were searched to 31st December, 2014. Inclusion criteria: 1) WSW included in the study population; 2) accepted BV diagnostic method; 3) investigated or could extrapolate factors(s) associated with BV acquisition, persistence or transmission in WSW specifically by comparing BV positive to BV negative women. Search was limited to English-language publications. Results A limited number of studies have investigated BV in WSW. Of 71 unique references, 18 full-text articles were assessed and 14 studies fulfilled inclusion criteria. BV was positively associated with higher numbers of female partners, both lifetime and in the three months prior to diagnosis, and confirmed BV in a female partner, but inconsistently associated with partners’ BV history or symptoms. BV was not associated with ethnicity, vaginal douching or hormonal contraception. The impact of specific sexual activities, male sexual contact, smoking and the menstrual cycle varied considerably between study populations. Conclusion BV in WSW is associated with increased numbers of recent and past female partners and confirmed BV in a female partner. There are limited studies of BV in WSW populations, and research is needed to further elucidate risk factors for BV among WSW. However these data provide epidemiological evidence that BV risk in women is directly related to exposure to other female partners and a partner with BV, providing support for the concept that BV is likely to be transmitted between women.

Testing nightscapes: Ghanaian Pentecostal politics of the nocturnal

Pentecostalism in Africa has developed a special relationship with the night as a time for conducting specific religious activities. Of these, the night vigil is the best known, with its underlying notions concerning darkness, invisible powers, faith and community. Ghanaian Pentecostals view the night as a kind of landscape where certain spaces and places become important to test the strength of one's personal faith and convictions, because the time after dark produces ambiguities of the good and the bad, or the superior and the inferior, of the spiritual powers that manifest themselves. Participation in Pentecostal night-time activities signals a modernity of Pentecostal beliefs and identities which, by confronting the powers of darkness, bring about a strengthening of the faith that churches and leaders aim to establish in interaction with their following. This contribution focuses on the Ghanaian community in The Hague, The Netherlands. It ventures to sensitize anthropology to the modernity of these forms of Christianity and the way they are becoming active producers of social and spiritual environments - defined here as Pentecostal nightscaping - as testing grounds for the efficacy of their faith.

Genome-wide association analysis

Genome-wide association (GWA) studies have become overwhelmingly popular in the last few years as a means to elucidate associations between particular alleles in one’s DNA and a predisposition to disease, using genetic data from unrelated individuals randomly sampled from a population (Balding, 2006; WTCCC, 2007). The recent availability of large amounts of such population genetic data necessitates the need to efficiently and accurately test for diseasesusceptiblity loci in a computationally viable manner. Single-marker-analysis (SMA), i.e. testing each DNA marker for disease association without including any information from additional DNA markers, has thus far been the primary tool for many GWA studies. However, ignoring the information from neighboring markers may significantly decrease the power to find associated markers. In particular, it is well known in population genetics that allelic types from nearby markers can be correlated, a phenomenon known as linkage disequilibrium (LD). Scientists have tried to exploit ideas of LD to increase the power for finding markers associated with disease status. The power gained by considering multiple markers in such a manner versus using simple SMA has been demonstrated in much recent literature (Zöllner and Pritchard, 2005; Minichiello and Durbin, 2006; Mailund et al., 2006; Marchini et al., 2007). The thus far most powerful of these methods (Zöllner and Pritchard, 2005) has used the notion of the coalescent to capture LD. The coalescent is a welldeveloped model that captures how the DNA of “unrelated” individuals may nonetheless be correlated due to the individuals’ shared ancestral history far enough back in time. Such methods attempt to reconstruct the ancestral recombination graph (ARG) of a sample, which represents the complete evolutionary history of the DNA of all the individuals in the sample. If the ARG can be accurately reconstructed for any particular region of the genome, one can check if the ARG has a tendency to cluster disease individuals and non-disesase individuals separately, which would be indicative of a potential disease-associated locus (or loci) in the region. While the method of Zöllner and Pritchard (2005) has proven highly accurate towards achieving this goal, its techniques for reconstructing the ARG are computationally expensive, so that the method cannot be applied to the large amounts of available genetic data we have today. Therefore, several new methods have been recently developed that less rigorously reconstruct the ARG (Minichiello and Durbin, 2006; Mailund et al., 2006). Such methods attempt
Models of Web-Like Graphs : Integrated Approach

The Web can be modeled as a directed graph in which a node represents a web page and an edge represents an hyperlink. Recent studies suggested that despite it chaotic appearance, the Web is highly structured graph, in a statistical sense. In this paper we introduce a new web-like model that incorporates the main features of the web: power law degree distributions for both incoming and outgoing links, “small world” structure and a large amount of small bipartite cliques. We also provide a comparison of our model with several others in their ability to capture web graph characteristics.
Research on on-line Uyghur character recognition technology based on center distance feature

In this paper, the center distance feature (CDF) is presented as an efficient approach for on-line Uyghur handwritten character recognition. Based on early research for on-line Uyghur handwritten character recognition, a further research is conducted with center distance feature, abbreviated as CDF. This paper introduces the extraction of center distance feature and its three different methods such as CDF-2, CDF-4 and CDF-8 which have improved the average recognition accuracy respectively to 78.17%, 90.47% and 94.50% for the 32 isolated forms of Uyghur characters. 12800 samples from 400 different writers are participated into experiments. The system is trained using 70 percent of total samples and tested on the remained 30 percent.
Absolute spectrophotometry of northern compact planetary nebulae

We present medium-dispersion spectra and narrowband images of six northern compact planetary nebulae (PNe): BoBn 1, DdDm 1, IC 5117, M 1-5, M 1-71, and NGC 6833. From broad-slit spectra, total absolute fluxes and equivalent widths were measured for all observable emission lines. High signal-to-noise emission line fluxes of Hα ,H β ,( O), (N), and HeI may serve as emission line flux standards for northern hemisphere observers. From narrow-slit spectra, we derive systemic radial velocities. For four PNe, available emission line fluxes were measured with sufficient signal-to-noise to probe the physical properties of their electron densities, temperatures, and chemical abundances. BoBn 1 and DdDm 1, both type IV PNe, have an Hβ flux over three sigma away from previous measurements. We report the first abundance measurements of M 1- 71. NGC 6833 measured radial velocity and galactic coordinates suggest that it is associated with the outer arm or possibly the galactic halo, and its low abundance ((O/H) = 1.3 × 10 −4 ) may be indicative of low metallicity within that region.
The spherical segmented Langmuir probe in a flowing thermal plasma: numerical model of the current collection

Abstract. The segmented Langmuir probe (SLP) has been recently proposed by one of the authors (Lebreton, 2002) as an instrument to derive the bulk velocity of terrestrial or planetary plasmas, in addition to the electron density and temperature that are routinely measured by Langmuir probes. It is part of the scientific payload on the DEMETER micro-satellite developed by CNES. The basic concept of this probe is to measure the current distribution over the surface using independent collectors under the form of small spherical caps and to use the angular anisotropy of these currents to obtain the plasma bulk velocity in the probe reference frame. In order to determine the SLP capabilities, we have developed a numerical PIC (Particles In Cell) model which provides a tool to compute the distribution of the current collected by a spherical probe. Our model is based on the simultaneous determination of the charge densities in the probe sheath and on the probe surface, from which the potential distribution in the sheath region can be obtained. This method is well adapted to the SLP problem and has some advantages since it provides a natural control of the charge neutrality inside the simulation box, allows independent mesh sizes in the sheath and on the probe surface, and can be applied to complex surfaces. We present in this paper initial results obtained for plasma conditions corresponding to a Debye length equal to the probe radius. These plasma conditions are observed along the Demeter orbit. The model results are found to be in very good agreement with those published by Laframboise (1966) for a spherical probe in a thermal non-flowing plasma. This demonstrates the adequacy of the computation method and of the adjustable numerical parameters (size of the numerical box and mesh, time step, number of macro-particles, etc.) for the considered plasma-probe configuration. We also present the results obtained in the case of plasma flowing with mesothermal conditions reproducing the case of measurements onboard a low altitude spacecraft. Finally, we briefly discuss the capabilities of the SLP to deduce the plasma bulk velocity under similar conditions and present the first onboard measurements. Keywords.

Valar Morghulis (All Parasocial Men Must Die): Having Nonfictional Responses to a Fictional Character

Previous research has found that parasocial relationships mirror actual social relationships. The purpose of this study is to determine how people reacted to the end of a parasocial relationship per a character death, by applying the Kubler-Ross Stages of Grief Model to Twitter reactions after the death of fictional character Jon Snow from the television show Game of Thrones. The applicability is discussed, as are directions for future research.
Quasi-simultaneous XMM-Newton and VLA observation of the non-thermal radio emitter HD 168112 (O5.5III(f^+))

We report the results of a multiwavelength study of the non-thermal radio emitter HD 168112 (O5.5III(f + )). The detailed analysis of two quasi-simultaneous XMM-Newton and VLA observations reveals strong variability of this star both in the X-ray and radio ranges. The X-ray observations separated by five months reveal a decrease of the X-ray flux of ∼30%. The radio emission on the other hand increases by a factor 5-7 between the two observations obtained roughly simultaneously with the XMM-Newton pointings. The X-ray data reveal a hard emission that is most likely produced by a thermal plasma at kT ∼ 2-3 keV while the VLA data confirm the non-thermal status of this star in the radio waveband. Comparison with archive X-ray and radio data confirms the variability of this source in both wavelength ranges over a yet ill defined time scale. The properties of HD 168112 in the X-ray and radio domain point towards a binary system with a significant eccentricity and an orbital period of a few years. However, our optical spectra reveal no significant changes of the star's radial velocity suggesting that if HD 168112 is indeed a binary, it must be seen under a fairly low inclination.
Towards a unified theory of consensus

We revisit the classic multi-agent distributed consensus problem. We adopt mild connectivity assumptions and with a novel application of the contraction coefficient we obtain simple yet general and unifying results both in discrete and continuous time. Furthermore, we extend the discussion to stochastic settings. We apply our approach to a wide variety of linear, nonlinear consensus and flocking algorithms proposed in the literature and we derive new conditions for asymptotic consensus.
The mental health and wellbeing of siblings of children with mental health problems: two decades of research.

While the importance of looking at the entire family system in the context of child and adolescent mental health is well recognised, siblings of children with mental health problems (MHPs) are often overlooked. The existing literature on the mental health of these siblings needs to be reviewed. A systematic search located publications from 1990 to 2011 in four electronic databases. Thirty-nine relevant studies reported data on the prevalence of psychopathology in siblings of target children with MHPs. Siblings of target children had higher rates of at least one type of psychopathology than comparison children. Risk of psychopathology varied across the type of MHP in the target child. Other covariates included sibling age and gender and parental psychopathology. Significant variations and limitations in methodology were found in the existing literature. Methodological guidelines for future studies are outlined. Implications for clinicians, parents, and for future research are discussed.
Evolution of gap junction proteins – the pannexin alternative

SUMMARY Gap junctions provide one of the most common forms of intercellular communication. They are composed of membrane proteins that form a channel that is permeable to ions and small molecules, connecting the cytoplasm of adjacent cells. Gap junctions serve similar functions in all multicellular animals (Metazoa). Two unrelated protein families are involved in this function; connexins, which are found only in chordates, and pannexins, which are ubiquitous and present in both chordate and invertebrate genomes. The involvement of mammalian pannexins to gap junction formation was recently confirmed. Now it is necessary to consider the role of pannexins as an alternative to connexins in vertebrate intercellular communication.
Evolution of faint radio sources in the VIDEO-XMM3 field

It has been speculated that low luminosity radio-loud AGN have the potential to serve as an important source of AGN feedback, and may be responsible for suppressing star-formation activity in massive elliptical galaxies at late times. As such the cosmic evolution of these sources is vitally important to understanding the significance of such AGN feedback processes and their influence on the global star-formation history of the universe. In this paper we present a new investigation of the evolution of faint radio sources out to z�2.5. We combine a 1 square degree VLA radio survey, complete to a depth of 100 µJy, with accurate 10 band photometric redshifts from the VIDEO and CFHTLS surveys. The results indicate that the radio population experiences mild positive evolution out to z�1.2 increasing their space density by a factor of �3, consistent with results of several previous studies. Beyond z=1.2 there is evidence of a slowing down of this evolution. Star-forming galaxies drive the more rapid evolution at low redshifts, z 1.2. The evolution is best fit by pure luminosity evolution with star-forming galaxies evolving as (1 + z) 2.47±0.12 and AGN as (1 + z) 1.18±0.21 .
Exploring and Enhancing Spatial Thinking

Although neglected in traditional education, spatial thinking plays a critical role in achievement in science, technology, engineering, and mathematics (STEM) fields. We review this relationship and investigate the malleability of spatial thinking. Can spatial thinking be improved with training, life experience, or educational interventions? Can improving spatial thinking improve STEM achievement? Research indicates that the answer is “yes” to both questions. A recent quantitative synthesis of 206 spatial training studies found an average training improvement of 0.47 standard deviations. Training effects lasted for months in studies examining durability and transferred to tasks that differed at least moderately from training tasks. A few studies indicate that spatial training can improve STEM learning, although more research needs to be done on this issue. We argue that including spatial thinking in STEM curricula could substantially increase the number of Americans with the requisite cognitive skills to enter STEM careers.
Representation of time-varying shapes in the large deformation diffeomorphic framework

Tracking and representation of shape change over time is of great interest in the field of computational anatomy. We propose a longitudinal growth model which estimates the diffeomorphic flow of a baseline image passing through a series of time-points that are the observed evolution of the template over time. We optimize the full space-time flow for the sequence of images, providing a linear space representation of the shape-change via a time-dependent velocity vector field, thus application of linear techniques becomes straightforward. We test our longitudinal growth model on both synthetic and real data-sets and demonstrate flexibility in time- point spacing, generation of average growth, and robust interpolation of missing time-points.
CPG-controlled asymmetric locomotion of a snake-like robot for obstacle avoidance

To realize the obstacle avoidance of a snake-like robot in unstructured environment, an asymmetric locomotion of snake-like robot is introduced. Imitating from the locomotion of natural snakes, the turn motion and the round motion of the snake-like robot are analyzed respectively. A CPG-based control system with parameter-transmitting characteristics is developed for control of the asymmetric locomotion. To verify the proposed control approach, both simulation and experiment of the snake-like robot for avoidance of an obstacle have been carried out.
Impact of ENPP1 K121Q on Change of Insulin Resistance after Web-Based Intervention in Korean Men with Diabetes and Impaired Fasting Glucose

Ectoenzyme nucleotide pyrophosphate phosphodiesterase 1 (ENPP1) gene has been studied in relation to type 2 diabetes mellitus (T2DM) and insulin resistance (IR). We hypothesized that the difference in genotype may be one of the factors that affect the outcome of intervention. We genotyped 448 men with fasting glucose≥5.6 mM/L, including 371 in subjects with K allele (KK) (69 control group [CG]; and 302 intervention group [IG]) and 77 in subjects with Q allele (KQ+QQ) (13 CG and 64 IG). The web-based intervention based on a lifestyle modification was delivered by e-mail once a month for 10 months. In the KK, IG demonstrated significantly decreased levels of fasting serum insulin (FSI) as compared to CG and homeostasis model of assessment of insulin resistance (HOMA-IR). In the KQ+QQ IG group, hemoglobin A1c (HbA1c), FSI and HOMA-IR were significantly decreased, and showed further reduction in the HOMA-IR than KQ+QQ CG. After analysis of covariance, K121Q did significantly influence the change of HbA1c in CG after appropriate adjustment. In a multivariate model, BMI change predicted HOMA-IR change (adjusted β=0.801; P=0.022) in KK IG subjects with T2DM. ENPP1 K121Q did not influence the change in IR. However, individuals with T2DM carrying the K121 variant are very responsive to the effect of BMI reduction on HOMA-IR. Graphical Abstract
Early Postnatal Astroglial Cells Produce Multilineage Precursors and Neural Stem Cells In Vivo

To identify the fates that astroglial cells can attain in the postnatal brain, we generated mice carrying an inducible Cre recombinase (Cre-ERT2) controlled by the human GFAP promoter (hGFAP). In mice carrying the GCE (hGFAP-Cre-ERT2) transgene, OHT (4-hydroxy-tamoxifen) injections induced Cre recombination in astroglial cells at postnatal day 5 and allowed us to permanently tag these cells with reporter genes. Three days after recombination, reporter-tagged cells were quiescent astroglial cells that expressed the stem cell marker LeX in the subventricular zone (SVZ) and dentate gyrus (DG). After 2–4 weeks, the tagged GFAP lineage included proliferating progenitors expressing the neuronal marker Dcx (Doublecortin) in the SVZ and the DG. After 4 weeks, the GFAP lineage generated mature neurons in the olfactory bulb (OB), DG, and, strikingly, also in the cerebral cortex. A major portion of all neurons in the DG and OB born at the end of the first postnatal week were generated from GFAP+ cells. In addition to neurons, mature oligodendrocytes and astrocytes populating the cerebral cortex and white matter were also the progeny of GFAP+ astroglial ancestors. Thus, genetic fate mapping of postnatal GFAP+ cells reveals that they seed the postnatal brain with neural progenitors/stem cells that in turn give rise to neural precursors and their mature neuronal and oligodendrocytic progeny in many CNS regions, including the cerebral cortex.
Neon Abundances from a Spitzer/IRS Survey of Wolf-Rayet Stars

We report on neon abundances derived from Spitzer high resolution spectral data of eight Wolf-Rayet (WR) stars using the forbidden line of [Ne III] 15.56 μm. Our targets include four WN stars of subtypes 4-7, and four WC stars of subtypes 4-7. We derive ion fraction abundances γ of Ne2+ for the winds of each star. The ion fraction abundance is a product of the ionization fraction Qi in stage i and the abundance by number 𝒜E of element E relative to all nuclei. Values generally consistent with solar are obtained for the WN stars, and values in excess of solar are obtained for the WC stars.
