SALES FROM REVIEW SENTIMENTS : The Differential Impacts of Expert and Online Customer Reviews on Amazon . com ’ s Book Sales and the Moderating Effect of Book Category

The past decades have seen the advent of online book retail and its explosive growth. As the popularity of online book retail continues to increase, so does the interest in understanding the predictors of online book sales. Accordingly, prior research has found evidence for the significant effects of traditional (I.e. expert reviews) and social earned media (i.e. online customer reviews) on online book sales. By literature review, the researcher pinpoints three main drawbacks of the extant literature. First, scholars have only been studying the effect of online customer reviews and expert reviews in isolation, regardless of the fact that they actually interact with each other while influencing online book sales in reality. Second, little research has been carried out to closely examine the impact of sentiment reviews on online book sales with sophisticated automated sentiment analysis technique. Third, the moderating role of book category was insofar neglected in scholarship. Drawing from these perspectives, this research sets out to investigate the differential impacts of traditional earned media (i.e. expert reviews) and social earned media (i.e. online customer reviews) on Amazon.com’s book sales. Additionally, it seeks to understand the moderating effect of book category on the impact of the positive sentiment in online customer reviews and expert reviews on Amazon.com’s book sales. The research is guided by the following research question: To what extent do traditional (i.e. expert reviews) and social earned media (i.e. online customer reviews) predict Amazon.com’s book sales? To answer the research question, the researcher conducts a quantitative research which consists of two steps of analyses. First, she performs a sentiment analysis on 1,133 reviews, using the sentiment analysis software LIWC 2015 (Linguistic Inquiry and Word Count), in order to detect the percentage of positive and negative sentiment in their textual content. Next, she conducts regression tests and z-score tests for regression coefficients to assess the hypotheses. The research provides practical recommendations for online book retailers to tailor their online communication strategy and budget so as to enhance sales performance. It, likewise, produces some important theoretical implications for future research to investigate the interplay between online customer reviews and expert reviews in influencing online book sales.
WIDE-APERTURE SEISMIC REFLECTION PROFILES ACROSS THE BARBADOS RIDGE COMPLEX 1

Wide-aperture seismic reflection profiles across the Barbados Ridge complex reveal the internal structure of the accretionary wedge as well as its overall geometry. In the north, where the wedge is only 100 km wide, the oceanic crustal reflection can be imaged westward beneath the entire accretionary wedge to a point where it meets an eastward-dipping reflection from the forearc basement. Farther south, where the wedge is as much as 300 km wide, the top of oceanic crust can be imaged 100 km west from the toe of the wedge, separated from the decollement by as much as 1 second of underthrust sediments. In the easternmost 50 km of the wedge near latitude 14° 20'N, eastward-verging thrusts and folds are imaged above the decollement. An eastward-dipping backthrust is imaged 110 km west of the toe of the wedge. Farther south at the latitude of Barbados, eastward-verging thrust packets are imaged 100 km west of the toe of the wedge. Seismic velocities determined from these profiles and associated expanding spread profiles and sonobuoys indicate low-velocity regions of the wedge separated laterally from higher velocity regions by zones of high lateral velocity gradients. These high-gradient zones correlate with marked changes in the slope cover lying on top of the wedge, changes in the reflection amplitude of the decollement reflection and oceanic crustal reflection, and locations of eastward-dipping back thrusts, suggesting episodic accretion.
Inescapable slow slip on the Altyn Tagh fault

GPS surveys conducted in 1994, 1998, and 2002 on the central portion of the Altyn Tagh fault confirm left‐lateral slip rates of 9 ± 4 mm/yr, significantly slower than geological estimates of slip rate for the past several thousand years. The measurements were obtained on a 300‐km‐long profile between 88° and 91°E within one fault dimension of the Mw = 7.6 and Mw = 7.8 Kunlun earthquakes of 1997 and 2001. The inferred elastic displacements from these events are incorporated into the interpreted 1994–2002 velocity field. The recent serendipitous occurrence of these two large earthquakes on a sub‐parallel fault system suggests that slip on the Kunlun fault may have recently accelerated, thereby reducing the slip rate on the Altyn Tagh fault. However, geodetic data from northern Tibet prior to the 2001 earthquake indicate present‐day rates similar to long term rates. This suggests that systematic errors may be present in published geologic slip rate estimates for the Altyn Tagh fault.
Metal Oxide Surge Arresters Modelling in Temporary Overvoltage Conditions

Insulation and protection system as part of the system of high voltage has been improved stability and reliability of distribution system is designed correctly and uses proper equipment.

Vibrations in stainless steel turning : multifractal and wavelet approaches

We investigate the experimental data of the turning process and the appearance of chatter vibrations. We focused on the turning of st ainless steel as the example of a special material, which belongs to a hardly machinable clas s. To characterize the vibration properties we used statistical, multifractal, and wavelet anal yses. The multifractal approach estimates complexity of the examined time series of the cutti ng thrust force. We report that the evolution of the vibration towards fairly large amplitude unw anted chatter with the increasing cutting depth coincides with lowering of the complexity. Th e results have been confirmed by continuous wavelet analysis.
Arbuscular mycorrhizal fungi associated with psammophilic vegetation in Mediterranean coastal sand dunes.

This study was conducted in order to characterize the natural arbuscular mycorrhizal (AM) biodiversity from Mediterranean sand dune ecosystems and to protect in a collection this biodiversity. The occurrence of AM fungi associated with sand dune plant species in three Mediterranean locations on the north-eastern coast of Spain was examined in one well preserved coastal sand dune and in two embrionary dunes recently protected from public access. Traditional taxonomy and molecular techniques were used to identify the AM fungal species present in these ecosystems. The species identified and isolated were: Scutellospora persica (Koske and Walker) Walker & Sanders, Glomus ambisporum Smith & Schenck, Glomus diaphanum Morton & Walker, Glomus clarum Nicolson & Schenck, Glomus intraradices Schenck & Smith, Glomus microaggregatum Koske, Gemma & Olexia and Gigaspora margarita Becker & Hall. Spores of Glomus were the most abundant in the direct soil extraction samples. The molecular analysis indicates that the most abundant fungi forming AM in the roots belonged to the Gigasporaceae group followed by fungi of Glomus group A and Glomus group B. The highest diversity of fungi and abundance of the AM fungal spores was found in the well preserved and undisturbed dune systems.
Title Blind Source Separation of Speech Signals : Exploiting Second Order Statistics Permalink

OF THE THESIS Blind Source Separation of Speech Signals: Exploiting Second Order Statistics by Vishaal Madanagopal Master of Science, Graduate Program in Electrical Engineering University of California, Riverside, March 2018 Dr. Yingbo Hua, Chairperson Blind source separation is a popular technique which is used in the fields of signal processing, audio, video and image processing. BSS is used to separate the mixed signals with only knowing the mixed signals and knowing very little about original signal characteristics. The separated signals should be very good approximations of the source signals. In particular, the blind source separation algorithm tries to estimate the Mixing Matrix. In my thesis, I have studied the blind source separation of signals based on its second order statistics. The problem of blind source separation is studied considering the following cases: when the signal is modelled as non-stationary, cyclo-stationary and quasi-stationary. A closed form solution to the blind source separation of speech signals considering speech to be a quasi-stationary source is studied and implemented.
Elsa Underhill workers ' employment rights ? Should host employers have greater responsibility for temporary agency

Many temporary agency workers receive poorer pay and employment conditions than workers performing similar tasks under traditional, direct hire arrangements. This is due to a number of factors, especially the failure in practice of employment regulation developed for standard employee–employer employment arrangements to be fully applicable in such indirect employment arrangements. This paper examines agency workers’ employment rights both against the standards of the International Labour Organization’s core labour rights, and in relation to occupational health and safety performance. The analysis demonstrates how a third party, the host employer, can influence the employment conditions of agency employees, yet bear limited responsibility for whether they satisfy minimum standards. These remain duties of the agency employer. The paper identifies a need to reconsider the legal responsibility of hosts and agency employers towards agency workers. Sharing responsibilities between hosts and agency employers may improve the likelihood of closing the gap between agency and direct hire workers’ employment
The influence of words on political marketing

This research focuses on the way politicians in the United States of America market themselves to the public. Specifically, the influence of linguistic markers in their use of language is studied. Using software, this research explores the differences in the vocabulary used by politicians running for president. Categories are formed that determine how politicians differ from each other for different variables. The probability for significant differences is modelled using independent t-test analyses. Findings illustrate statistically significant results in almost all analyses.
DP RIETI Discussion Paper Series 17E-062 Bank-Firm Relationship and Small Business Innovation

This paper empirically investigates the effect of banks’ soft information on small business innovations. Using data from a sample of Japanese small and medium enterprises (SMEs), we find that multiple banking prevails. Moreover, besides the main bank, the sub bank also acquires soft information for a number of multiple banking firms. Nonetheless, there coexists no bank information: the main bank’s information monopoly and multiple bank information competition. Importantly, such information competition in multiple banking is positively related to both product and process innovation while the main bank’s information monopoly has no significant effects on innovation. Also, we offer additional consistent evidence that information competition decreases the likelihood of worsening of the lending attitude of the main bank during the financial crisis. For single banking firms, bank information monopolies have a negative effect on product and process innovation.
Interactive comment on “ Amorphous and crystalline aerosol particles interacting with water vapor – Part 1 : Microstructure , phase transitions , hygroscopic growth and kinetic limitations ” by E .

interactions into a single publication. It contains detailed discussion on the HTDMA technique, various phase transitions including amorphous phases and gels, and water activity modeling. The paper is thoroughly researched and generally well written. However, the manuscript is repetitive in parts and much of the discussion should be presented in a significantly more concise form. The proposed particle microstructure and phase transitions are plausible and thought provoking. Nevertheless, by the authors own admission, it is difficult to unambiguously distinguish between restructuring and solid to semi-solid phase transitions just by measuring changes in dry particle size. In the manuscript only three compounds are examined, all of which have been reported on before in the peer-reviewed literature. This is mainly justified due to improvements in measurement accuracy and the inclusion of evaporation data and heterogeneity measures. In the final section of the manuscript, the growth factor data are modeled using a variety of currently used techniques, providing interesting insights into the non-ideal behavior of aqueous ammonium sulfate, oxalic acid, and levoglucosan solutions. The paper meets the standards of ACP and I recommend it for publication after addressing my concerns outlined below.
The prevalence of Plasmodium falciparium among three stages of pregnancy in Dogon Dawa, Nigeria

A study of the efficacy of ITNs and chemoprophylaxis (SP) in preventing malaria in pregnant women was carried out at Dogon Dawa District. Birnin Gwari Local Government Area, Kaduna State. The Inclusion criteria for women in the survey were that: The woman is aged 15-49,pregnancy is confirmed by a health care provider on site, she is attending the antenatal clinic for the first time, the woman accepts malaria testing, have no chronic illness or severe form of malaria, not sick at the time of recruitment, none of the women that participated in this study -were sleeping under bednet as at the time of the study. Out of a total of 500 pregnant women attending Dogon Dawa primary health center, 150 were enrolled for the study. Thirty (20.2%) of Antenatal clinic attendees were primigravidia while 108 (73.0%) were multigravidia and 10 (6.7%) did not respond to whether it was their first pregnancy. Among the study population, 20 (13.5%) were in their first trimester. 58(39.2%), in the second trimester and 54(36.5%) in their third trimester. The subjects were divided into groups. Group 1 had fansidar only (SP), Group 2 had untreated net only, Group 3 had insecticide treated net (ITNs) and Group 4 had insecticide treated net (ITNs) and fansidar and Group 5 had no fansidar and no insecticide treated net. Prevalence of Plasmodium falciparum showed higher infection rate with group 5 using no fansidar and no treated net with p<0.01. The Drugs used for fever by pregnant women were chloroquine, fansidar and herbal tea; herbal tea had highest prevalence, Among the drugs used by pregnant women against malaria, Herbal tea and Fansidar showed high significant difference. From the findings in this study, it was could be concluded that house wives, women with no formal education and pregnant women within the age of (16-25 yrs) had the highest prevalence of the parasite. The findings also revealed that the use insecticide treated net and fansidar are effective in the control of the transmission of the parasite. It has been showed, that the highest prevalence could be attributed to exposure to the vector and ignorance about malaria transmission and its treatment.
THE ECONOMIC DETERMINANTS OF SEASONAL PATTERNS . SEASONALITY IN MONTHLY INTERNATIONAL TOURIST ARRIVALS TO THE BALEARIC ISLANDS

Seasonal variation in demand is a well-documented phenomenon in tourism literature. For the tourism industry, seasonality is a problem related to the efficient use of capacity. Although there is a general agreement that certain characteristics influence the shape of the seasonality curve (i.e. the climate, institutional patterns like school holidays or calendar holidays, special events etc.), there is no scientific theory on tourism seasonality. The purpose of this paper is to provide evidence about the influence of some economic variables over the seasonal pattern of tourist arrivals using the Gini Coefficient and regression analysis.
PROBING TRAPPIST-1-LIKE SYSTEMS WITH K2

The search for small planets orbiting late M dwarfs holds the promise of detecting Earth-size planets for which their atmospheres could be characterized within the next decade. The recent discovery of TRAPPIST-1 entertains hope that these systems are common around hosts located at the bottom of the main sequence. In this Letter, we investigate the ability of the repurposed Kepler mission (K2) to probe planetary systems similar to TRAPPIST-1. We perform a consistent data analysis of 189 spectroscopically confirmed M5.5 to M9 late M dwarfs from Campaigns 1–6 to search for planet candidates and inject transit signals with properties matching TRAPPIST-1b and c. We find no transiting planet candidates across our K2 sample. Our injection tests show that K2 is able to recover both TRAPPIST-1 planets for 10% of the sample only, mainly because of the inefficient throughput at red wavelengths resulting in Poisson-limited performance for these targets. Increasing injected planetary radii to match GJ 1214b’s size yields a recovery rate of 70%. The strength of K2 is its ability to probe a large number of cool hosts across the different campaigns, out of which the recovery rate of 10% may turn into bona fide detections of TRAPPIST-1-like systems within the next two years.
Association Between Serum Ferritin Levels and Insulin Resistance in Nondiabetic Brazilians

Background: Previous studies have pointed to a relation between high serum levels of ferritin and insulin resistance. Objective: To analyze the association between the serum concentrations of ferritin and resistance to insulin, and metabolism of glucose, in nondiabetic persons. Method: A transversal study was undertaken with 151 nondiabetic persons in Sao Luis, Brazil, in 2013. The following biochemical variables were analyzed: glycated hemoglobin, fasting glycemia, fasting insulin, total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, serum ferritin and high-sensitivity C reactive proteins (hs-CRP). Results: Among the participants with high levels of ferritin, approximately 20% and 40%, respectively, also had raised LDL-C (p=0.040) and hs-CRP (p=0.021). Prediabetes (p=0.016) and insulin resistance (p=0.026) had a statistically significant association with high levels of ferritin. The participants with raised ferritin also had double the probability of having raised hs-CRP (odds ratio = 2.29 / p=0.036). Conclusion: There was a statistically significant association between prediabetes and insulin resistance and raised levels of ferritin.
Resistant starch: Importance, categories, food sources and physiological effects

The present day resistant starch consumption has become popular as it proved to improve insulin sensitivity, lower blood sugar levels, reduces appetite and has beneficial effects on colon. Resistant starch has various benefits for metabolic health. It also has a "second meal effect" meaning that if you eat resistant starch with breakfast, it will also lower the blood sugar spike at lunch. The aim of present study is ascertain the importance of consumption of resistance starch and to understand its effects.

Covariance constraints for stochastic inverse problems of computer models

Stochastic inverse problems are typically encountered when it is wanted to quantify the uncertainty affecting the inputs of computer models. They consist in estimating input distributions from noisy, observable outputs, and such problems are increasingly examined in Bayesian contexts where the targeted inputs are affected by stochastic uncertainties. In this regard, a stochastic input can be qualified as meaningful if it explains most of the output uncertainty. While such inverse problems are characterized by identifiability conditions, constraints of"signal to noise", that can formalize this meaningfulness, should be accounted for within the definition of the model, prior to inference. This article investigates the possibility of forcing a solution to be meaningful in the context of parametric uncertainty quantification, through the tools of global sensitivity analysis and information theory (variance, entropy, Fisher information). Such forcings have mainly the nature of constraints placed on the input covariance, and can be made explicit by considering linear or linearizable models. Simulated experiments indicate that, when injected into the modeling process, these constraints can limit the influence of measurement or process noise on the estimation of the input distribution, and let hope for future extensions in a full non-linear framework, for example through the use of linear Gaussian mixtures.
1 Which criteria matter most in the evaluation of venture capital investments ?

This study identifies the importance assigned to the various criteria used by the Portuguese Venture Capitalists (VCs) to evaluate and select early stage venture capital projects. The data was collected through a questionnaire answered by 20 Portuguese VCs. We use descriptive statistics techniques and non-parametric tests to identify the most valued criteria and test differences in the importance assigned to the criteria of several types of VCs and investments. The study reveals that the personality and experience of the entrepreneur and of the management team are the most valued groups of criteria. VCs with a majority of private share capital value more the personality of the entrepreneur and management team than the companies with a majority of public share capital. Additionally, the VCs that did not yet internationalize consider the personality of the entrepreneur and management team and the financial aspects, to be more important than the VCs that have already expanded abroad.
Food demand in Vietnam: structural changes and projections to 2030

Rank three demand systems have been recognized to be best-suited for long-term demand projections due to their Engel flexibility. Using a fitted QUAIDS model, food demand in Vietnam is projected under scenarios that account for alternative growth rates in food expenditures, food prices and urbanization. Results indicate that at higher levels of expenditure growth, budget share of rice declines while budget shares of high-valued foods such as meat and drinks increase. Demand for rice is projected to decline in 2020 and further in 2030 both on a per capita basis and in total while demand for other foods increases. The projections also show that the effect of urbanization is more remarkable for rice while it is modest for non-rice food groups. Results of this study highlight the importance of considering the effect of income distribution and urbanization in long-term food demand projections.
