Identifying Effective Signals to Predict Deleted and Suspended Accounts on Twitter Across Languages

Social networks have an ephemerality to them where accounts and messages are constantly being edited, deleted, or marked as private. This continuous change comes from concerns around privacy, a potential desire for to be forgotten and suspicious behavior. In this study we present a novel task – predicting suspicious e.g., to be deleted or suspended accounts in social media. We analyze multiple datasets of thousands of active, deleted and suspended Twitter accounts to produce a series of predictive representations for the removal or shutdown of an account. We selected these accounts from speakers of three languages – Russian, Spanish, and English to evaluate if speakers of various languages behave differently with regards to deleting accounts. We compared the predictive power of the state-of-the-art machine learning models to recurrent neutral networks trained on previously unexplored features. Furthermore, this work is the first to rely on image and affect signals in addition to language and network to predict deleted and suspended accounts in social media. We found that unlike widely used profile and network features, the discourse of deleted or suspended versus active accounts forms the basis for highly accurate account deletion and suspension prediction. More precisely, we observed that the presence of certain terms in tweets leads to a higher likelihood for that user’s account deletion or suspension. Moreover, despite image and affect signals yield lower predictive performance compared to language, they reveal interesting behavioral differences across speakers of different languages. Our extensive analysis and novel findings on language use and suspicious behavior of speakers of different languages can improve the existing approaches to credibility analysis, disinformation and deception detection in social media.
A responsive evaluation of mental health treatment in Cambodia: Intentionally addressing poverty to increase cultural responsiveness in therapy

Mental health issues are significant contributors to the global burden of disease with the highest incidence in resource poor countries; 90% of those in need of mental health treatment reside in low resource countries but receive only 10% of the world's resources. Cambodia, the eighth least developed country in the world, serves as one example of the need to address mental health concerns in low-income, resource poor countries. The current study utilises responsive evaluation methodology to explore how poverty-stricken Cambodian clients, therapists and supervisors experience Western models of therapy as culturally responsive to their unique needs. Quantitative and qualitative data were triangulated across multiple stakeholders using numerous methods including a focus group, interviews, surveys, case illustrations and live supervision observation and analysed using constant comparative analysis. Emerging findings suggest that poverty, material needs, therapy location and financial situations greatly impact the daily lives and mental health conditions of Cambodians and hinder clients' therapeutic progress. The local community needs and context of poverty greatly hinder clients' therapeutic progress in therapy treatment and when therapy does not directly address the culture of poverty, clients did not experience therapy as valuable despite some temporary decreases in mental health symptoms.
Use of cash in France: the payment method of choice for low-value purchases

This article exploits French data from a survey of cash usage in the euro area, which was published in 2017 on behalf of the European Central Bank (ECB). Cash is the preferred method of payment at the point of sale in the euro area, accounting for three out of every four transactions and more than half of the total value of purchases. The survey results nonetheless vary across countries, with France in particular showing a high concentration of cash usage for small purchases, coupled with a strong predilection for cashless means of payment. Among the determinants of cash usage, sociodemographic criteria (gender, age, income and profession of consumers) are found to have very little impact. However, transaction characteristics play a predominant role, with the share of cash payments diminishing as the value of the purchase rises, and increasing for purchases in shops for day-to-day items.
Ultrawideband MIMO Channel Measurements and Modeling in a Warehouse Environment

This paper presents a detailed description of a propagation channel measurement campaign performed in a warehouse environment and provide a comprehensive channel model for this environment. Using a vector network analyzer, we explored both line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios over a 2-8 GHz frequency range. We extracted both small-scale and large-scale channel parameters such as distance-dependent path loss exponent, frequency-dependent path loss exponent, shadowing variance, and amplitude fading statistics of the channel. We also provide the clustering analysis of the channel impulse responses by using a modified Saleh-Valenzuela approach. Our model is validated by comparing the distributions of the root-mean-square (RMS) delay spread obtained from our model and measurement data, respectively. The model developed can be used for realistic performance evaluations of ultrawideband (UWB) communications and localization systems in warehouse environments.
Arbuscular mycorrhizal fungi and vermicompost to maximize the production of foliar biomolecules in Passiflora alata Curtis seedlings.

BACKGROUND Arbuscular mycorrhizal fungi (AMF) are soil organisms that associate with plant roots and promote plant growth, increasing the concentration of secondary metabolites, which are molecules of interest to the pharmaceutical industry. Passiflora alata is a Brazilian medicinal plant that is used as a raw material for anxiolytic phytotherapeutic agents. The anxiolytic properties are related to the presence of biomolecules in the plant material, principally flavonoids. The objective of this study was to evaluate the effect of inoculation with AMF and organic fertilization on the production of soluble carbohydrates and total foliar proteins, phenols and flavonoids in P. alata seedlings. RESULTS There was an effect of the tested treatments on the analyzed variables. Seedlings inoculated and cultivated in soil to which 0.15 kg vermicompost kg(-1) had been added showed increased growth and production of primary and secondary metabolites compared with treatments with lower levels of manure, which did not differ from those cultivated in soil with 0.2 kg vermicompost kg(-1). CONCLUSION The inoculation of P. alata seedlings with Gigaspora albida is an alternative to maximize the production of pharmacologically important foliar biomolecules, especially flavonoids, with benefits that vary in accordance with the fertility of the soil.
Investigation of the relationship between firm-wise financial factors and firm performance in the hospitality industry

Investigation of the Relationship between Firm-wise Financial Factors and Firm Performance in the Hospitality Industry by Zhenxing Mao Dr. Zheng Gu, Examination Committee Chair Professor of Hotel Administration University of Nevada, Las Vegas This study empirically investigates the relationship between firm-wise financial factors and firm performance in the hospitality industry from 2000 to 2004 using panel data regression. After a literature review of firm-wise financial factors and their impact on performance in the literature, unit-effect and time-effect linear models were proposed and examined in both the restaurant and hotel sectors with different firm performance measures used as the dependent variable (i.e. Proxy Q, Sharpe ratio, and Treynor ratio). While some variables, especially liquidity and solvency, were found to have significant impacts on firm performance measured by Proxy Q and Sharpe ratio in both the restaurant and hotel sectors, no financial variable was found to have a significant relationship with the Treynor ratio in either sector. Implications of this study’s findings for both the restaurant and hotel sectors are discussed at the end.
What Do Post-Communist Countries Have in Common When Predicting Financial Distress?

Business failure prediction is an important issue in corporate finance. Different prediction models are proposed by financial theory and are often used in practice. Their application is effortless, selecting only few key inputs with the greatest informative power from the large list of possible indicators. Our paper identifies the financial distress predictors for 5 post-communist countries (Bulgaria, Croatia, the Czech Republic, Hungary and Romania) based on information collected from the Amadeus database for the period 2011-2013 using CHAID decision trees and neural networks. We propose a short list of indicators, which can offer a synthetic perspective on corporate distress risk, adapted for these countries. The best prediction models are substantially different from country to country: in the Czech Republic, Hungary and Romania the flow-approach indicators perform better, while in Bulgaria and Croatia - the stock-approach indicators. The results suggest that the extrapolation of such models from one country to another should be made cautiously. One interesting finding is the presence of the ratios per employee as predictors of financial distress.
A New Approach to Estimating the Path Loss in Underground Wireless Sensor Networks

Unlike terrestrial Wireless Sensor Networks (WSNs), communication between buried nodes in WUSNs happens through the ground. Due to the complexity of soil, accurate estimation of the underground signal attenuation is challenging. Existing path loss models mainly rely on semi-empirical and empirical mixing models for calculating the dielectric properties of the soil. In this paper, two existing models for estimating the path loss in soil (i.e., the CRIM-Fresnel and Modified-Friis models) are compared with measurements obtained at three locations. In addition, an improved method is proposed for estimating the path loss based on a new approach for calculating the dielectric properties of soil from Time Domain Reflectometry (TDR) measurements. The proposed approach calculates the complex permittivity values from TDR waveform based on a new modified method and subsequently use them as inputs into the Modified-Friis model. The results from the field trials were compared with the proposed method and the existing models. The results of this comparison showed that the proposed estimation technique provides a better estimation of Radio Frequency (RF) attenuation than the existing models. It also eliminates the need to take samples back to the laboratory by providing in situ calculation of attenuation based on TDR.
An evaluation of e-word-of-mouth communication on brand equity in Cross River State, Nigeria | University of Nigeria, Nsukka Open Education Resources (OER)

Word of mouth testimonial on organizations’ brands are presently moving in the super high-way of the social network, the internet and other digital medium such as Facebook, Email, MMS, Google, and YouTube, SMS messages etc. The quintessential of brand equity no doubt has relativeness with e-Word-of-Mouth communication; where consumers air out their experiences through electronic means. Surprisingly, little in the way of empirical research is available, that quantifies the effect of e-WOM on brand equity in Nigeria. To this end, the survey research design was employed and data were collected from the customers of selected GSM operators in Nigeria. The Ordinary Least Square was used for the hypotheses and it was discovered that e-WOM influences brand awareness, brand association, perceived brand equity, and brand loyalty. It was therefore recommended that, organizations should spur discussion about their brands through the internet and where a trustworthy source like the social network is used to communicate consumers’ experiences; it will contribute in no small measure to brand familiarization, establishment of brand equity and ensure unique association with the brand that gives the required satisfaction, benefit and solution.

Spectral simplification for resolved glutamate and glutamine measurement using a standard STEAM sequence with optimized timing parameters at 3, 4, 4.7, 7, and 9.4T

The C4 multiplet proton resonances of glutamate (Glu) around 2.35 ppm and glutamine (Gln) around 2.45 ppm usually overlap in MR spectra, particularly at low‐ and mid‐field strengths (1.5–4.7T). A spectral simplification approach is introduced that provides unobstructed Glu and Gln measurement using a standard STEAM localization sequence with optimized interpulse timings. The underlying idea is to exploit the dependence of response of a coupled spin system on the echo time (TE) and mixing time (TM) to find an optimum timing set (TE, TM), at which the outer‐wings of C4 “pseudo‐triplet” proton resonances of Glu and Gln are significantly suppressed while the central peaks are maintained. The spectral overlap is thus resolved as the overlap exists exclusively at the outer‐wings and the central peaks are readily separated due to the approximate 0.1‐ppm difference in chemical shift. Density matrix simulation for Glu, Gln, and other overlapping metabolites at 2.3–2.5 ppm was conducted to predict the optimum timing sets. The simulated, phantom, and in vivo results demonstrated that the C4 multiplet proton resonances of Glu and Gln can be resolved for unobstructed detection at 3T, 4T, and 4.7T. For simplicity, only simulated data are illustrated at 7T and 9.4T. Magn Reson Med 59:236–244, 2008. © 2008 Wiley‐Liss, Inc.
Secondary Electron Emission Measurement of Insulating Materials for Spacecraft

We studied how to measure the secondary electron emission (SEE) of metal and insulating materials used for satellite thermal insulation or other such purposes. SEE yield measurement is very important for analyzing charge accumulation on the satellite surfaces due to the space environment because electron emission due to irradiated electrons influences the amount of surface charge. Therefore, we tried to measure the SEE yield. To measure SEE, we used an improved SEM system for SEE measurement that has a beam blanking unit and a Faraday cup. From this system, we can obtain the characteristics of the SEE yield from insulation materials irradiated by an electron beam with energy of 600eV to 5keV. In this report, we introduce the SEE yield measurement results of reference materials (Au, Ag and quartz glass) and insulating materials. From those results, we discuss the characteristics of SEE that depend on each material. Furthermore, we also propose a future plan of SEE measurement for satellite materials
Effects of vagal stimulation and applied acetylcholine on pacemaker potentials in the guinea‐pig heart.

1. Intracellular recordings were made from pacemaker cells lying in the sino‐atrial node of guinea‐pigs. 2. Low‐frequency vagal stimulation slowed the rate of generation of pacemaker action potentials; high‐frequency stimulation stopped the generation of action potentials. 3. During vagal stimulation the rate of diastolic depolarization was reduced with the action potential otherwise unchanged: when the heart stopped the membrane potential of pacemaker cells settled to a value positive of the maximum diastolic potential. 4. In contrast, added acetylcholine caused membrane hyperpolarization and shortened the duration of action potentials. 5. The effects of both added acetylcholine and vagally released acetylcholine were abolished by hyoscine. 6. It is suggested that neurally released acetylcholine acts to change the balance between inward and outward current flow during diastole by modifying the properties of existing voltage‐dependent channels. In contrast added acetylcholine appears to activate a different set of receptors which increase the potassium conductance of pacemaker cells.

[Effects of epidural ropivacaine labor analgesia on duration of labor and mode of delivery].

OBJECTIVE To study the effects of ropivacaine on the duration of labor and mode of delivery in the primigravidas using patient-controlled epidural analgesia (PCEA). METHODS Retrospective analysis was performed. The 190 healthy, full-term, and single-fetus parturient primigravidas who received PCEA with 0.1% ropivacaine + fentanyl (1 microg/ml) were in the epidural analgesia group. Another 222 primigravidas who did not receive PCEA were in the control group. The duration of labor and modes of delivery, and the neonatal Apgar scores in both two groups were recorded and evaluated. RESULTS Those in the epidural analgesia group experienced a significantly longer first stage [(426 +/- 161) minutes], longer second stage [(54 +/- 27) minutes] and longer full duration of delivery [(489 +/- 166) minutes] than those in the control one [(409 +/- 170) minutes, (364 +/- 167) minutes and (37 +/- 22) minutes]. The rate of using pitocin in the epidural analgesia group (30.2%) was significantly higher than that in the control group (4.1%). The cesarean section rate in epidural analgesia group (20.0%) was lower than that in the control one (28.4%); while the rate of instrumental delivery in the epidural analgesia group (20.0%) was significantly higher than that in the control one (6.3%). In summary, there were significant differences between two groups in the duration of labor, the rate of using pitocin, the rate of instrumental delivery and the rate of cesarean section. But there were no differences found for those newborn who had Apgar scores less than 7 at the point of both one and five minutes (7.9% and 4.5%, 2.6% and 0.5% respectively). CONCLUSION Epidural ropivacaine labor analgesia lengthens the duration of labor and increases the rate of instrumental delivery, but it has no significant negative effects on the neonates.
Abscisic Acid–Responsive Guard Cell Metabolomes of Arabidopsis Wild-Type and gpa1 G-Protein Mutants[C][W]

The authors performed metabolomics analysis on a time series of guard cell samples treated with abscisic acid (ABA) to follow the dynamics of 85 metabolites potentially involved in ABA signaling. ABA rapidly altered the profiles of numerous metabolites, including other hormones and calcium-mobilizing agents. ABA responses were greater in the wild type than in a G-protein mutant with ABA-hyposensitive stomata. Individual metabolites have been implicated in abscisic acid (ABA) signaling in guard cells, but a metabolite profile of this specialized cell type is lacking. We used liquid chromatography–multiple reaction monitoring mass spectrometry for targeted analysis of 85 signaling-related metabolites in Arabidopsis thaliana guard cell protoplasts over a time course of ABA treatment. The analysis utilized ∼350 million guard cell protoplasts from ∼30,000 plants of the Arabidopsis Columbia accession (Col) wild type and the heterotrimeric G-protein α subunit mutant, gpa1, which has ABA-hyposensitive stomata. These metabolomes revealed coordinated regulation of signaling metabolites in unrelated biochemical pathways. Metabolites clustered into different temporal modules in Col versus gpa1, with fewer metabolites showing ABA-altered profiles in gpa1. Ca2+-mobilizing agents sphingosine-1-phosphate and cyclic adenosine diphosphate ribose exhibited weaker ABA-stimulated increases in gpa1. Hormone metabolites were responsive to ABA, with generally greater responsiveness in Col than in gpa1. Most hormones also showed different ABA responses in guard cell versus mesophyll cell metabolomes. These findings suggest that ABA functions upstream to regulate other hormones, and are also consistent with G proteins modulating multiple hormonal signaling pathways. In particular, indole-3-acetic acid levels declined after ABA treatment in Col but not gpa1 guard cells. Consistent with this observation, the auxin antagonist α-(phenyl ethyl-2-one)-indole-3-acetic acid enhanced ABA-regulated stomatal movement and restored partial ABA sensitivity to gpa1.
