Exploring the Incongruence Between Product Descriptions and Customer Reviews to Complement Traditional Product Development

This research delivers an approach to examine the observed content differences between video game product descriptions and their respective customer reviews on Amazon. The aim is to better align the message sent by companies with what customers care about. Using human judges, it elicits prevalent features across product descriptions and matches these features based on whether they are mentioned in the respective customer reviews. MCA is used to establish the extent and structure of the mismatch. Thus, the existence of an incongruence between these text forms spanning the video game category is demonstrated. Given this, an individual product is singled out to explore the incongruence: Call of Duty: Ghosts. This sets an example of how a product manager might attempt to better align their product description with customer reviews. Aiming to use automation to resemble the task of human judges, LDA is used to generate topics in positively-rating reviews and contrasted with topics in negatively-rating reviews. The findings are used to recommend adjustments to the wording of the description and future product development decisions. The biggest issue customers complain about appears to be related to the servers. As suggested by the interpretation of LDA topics for the two corpora, the product description for the game in question should be adjusted to reflect well-received aspects and avoid problematic features. Product development should pay more attention to deliver reliable technical customer support and invest to improve the unsatisfactory parts of the game.
Universality of fractal aggregates as probed by light scattering

Fractal colloid aggregates are studied with both static and dynamic light scattering. The dynamic light scattering data are scaled onto a single master curve, whose shape is sensitive to the structure of the aggregates and their mass distribution. By using the structure factor determined from computer-simulated aggregates, and including the effects of rotational diffusion, we predict the shape of the master curve for different cluster distributions. Excellent agreement is found between our predictions and the data for the two limiting régimes, diffusion-limited and reaction-limited colloid aggregation. Furthermore, using data from several completely different colloids, we find that the shapes of the master curves are identical for each régime. In addition, the cluster fractal dimensions and the aggregation kinetics are identical in each régime. This provides convincing experimental evidence of the universality of these two régimes of colloid aggregation.
Synthesis and Properties of Calix[4]arene‐bis[4‐(2‐ethylhexyl)benzo‐crown‐6], A Cesium Extractant with Improved Solubility

Abstract The new cesium‐selective macrocycle calix[4]arene‐bis[4‐(2‐ethylhexyl) benzo‐crown‐6] (“BEHBCalixC6”) has been found to have improved solubility in a modified alkane diluent over calix[4]arene‐bis(4‐tert‐octylbenzo‐crown‐6) (“BOBCalixC6”). The synthesis of this new calixcrown extractant, together with its solubility and extraction properties, is described in this report. The solubility, cesium extraction, and potassium loading behavior are compared with those of BOBCalixC6, the macrocycle currently employed in the caustic‐side solvent extraction (CSSX) process for extracting cesium from alkaline nitrate solutions such as high‐level nuclear waste. Replacement of the tert‐octyl alkyl chains on the benzo‐crown portion of the calixcrown by 2‐ethylhexyl chains improves the equilibrium solubility of the free calixcrown in aliphatic diluents while not affecting the cesium extraction strength. Equilibrium concentrations of BEHBCalixC6 in Isopar L diluent modified with 0.5 M 1‐(2,2,3,3‐tetrafluoropropoxy)‐3‐(4‐sec‐butylphenoxy)‐2‐propanol (Cs‐7SB) over the course of 41 weeks of gentle agitation at 25°C maintained the initial concentration of 57 ± 2 mM, with no evidence of precipitation or third‐phase formation. In contrast, 57 ± 2 mM solutions of BOBCalixC6 prepared using sonication were not stable, with precipitation occurring to afford an equilibrium concentration of only 6.7 ± 0.2 mM after 41 weeks. Third‐phase tests showed that BEHBCalixC6 resists third‐phase formation as well as, or better than, BOBCalixC6. With increasing potassium loading from an alkaline sodium nitrate solution, both calixcrowns at 20 mM in modified Isopar L exhibited comparable onset of third‐phase formation, gauging by the decreasing mass balance in cesium extraction from the same solutions. However, the BEHBCalixC6 solvent exhibited no visible indications of third‐phase formation until the aqueous potassium concentration reached 0.75 M, whereas the BOBCalixC6 suffered visible third‐phase formation when the aqueous potassium nitrate concentration reached 0.25 M. Calixcrowns with higher solubility in alkane diluents may find application in cesium extraction from waste matrices containing moderate (≥0.2 M) quantities of potassium, such as that stored at the US Department of Energy's Hanford Site, where higher concentrations of the calixcrown extractant may be required to obtain practical cesium distribution coefficients for process flowsheets.
Gênese de horizonte coeso, fragipã e duripã em solos do tabuleiro costeiro do sul da Bahia

The genesis of cohesive horizons in some soils is not well known yet and, in many cases, it is conflicting. The purpose of this study was to evaluate physical, chemical and mineralogical mechanisms that cause hardening in soils with cohesive horizons, fragipan and duripan in Brazilian Coastal Plain soils. Soil samples of two toposequences were sampled and the taxonomic classes of the soils were identified as Argisolic Eutrophic Red Latosol, Latosolic Dystrophic Yellow Argisol for the first toposequence, and Abruptic Dystrophic Yellow Argisol, Dystrophic Typic Yellow Argisol and Duric Orthic Carbic Spodosol, for the second sequence. The chemical analysis performed were Fe, Si, and Al extraction with sodium dithionite-citrate-bicarbonate (DCB) and ammonium oxalate. The clay fraction mineralogy was evaluated by X-ray diffraction. Soils with cohesive horizons presented very low Fe, Si, and Al contents extracted with both DCB and oxalate. Nevertheless, soil with fragipan and duripan showed high Si and Al content extracted with oxalate, indicating their role as cementing agents. The Argisol clay fraction is predominantly kaolinitic, and gibbsite was only found in the Bt1, Bt2 and Bw horizons of the Latosolic Yellow Argisol. Gibbsite was found in soils with fragipan and duripan (Duric Orthic Carbic Spodosol), and despite being considered a disorganizing agent of kaolinite adjustment, the hardpan characteristics were maintained. Thus, the hardening mechanisms of these soils seem different for cohesive, fragipan and duripan horizons.
APPLICATION OF POWER LAW LOGISTIC MODEL TO GROWTH KINETICS OF BACILLUS LICHENIFORMIS MS3 ON A WATER-INSOLUBLE SUBSTRATE

The power law logistic model was utilized to investigate the growth of a hydrocarbon assimilating bacterium on a water-insoluble substrate. To achieve this end, population dynamics of Bacillus licheniformis MS3 in a medium containing n-decane as the sole carbon source was monitored for 30 h. Different initial biosurfactant concentrations and shaking rates were employed to examine the role of mass transfer in the cell growth and the consequent hydrocarbon biodegradation. The amount of n-decane degraded in the system was detected by gas chromatography at the end of the incubation period. The results revealed that when mass transfer limitations were lessened through addition of an initial biosurfactant concentration and agitation, the bacterial growth increased more than three times and the n-decane biodegradation was enhanced from 6.7 to 15.1 mg/100 mL. Finally, the power law logistic model proved to be highly capable in simulating both the experimental results and various systems with water-insoluble carbon sources.
Magnetovolume effect of itinerant electron ferromagnets

The magnetovolume effect of itinerant electron magnets is discussed by the explicit examination of the volume dependence of the spin fluctuation free energy. Magnetic Grüneisen parameters are introduced instead of magnetovolume coupling constants, that enable us to describe all the magnetovolume properties in terms of these parameters. We have particularly found the presence of a new thermal expansion, showing T2-like temperature dependence. It explains the appreciable electronic volume thermal expansions observed experimentally. We also show that the magnetovolume coupling constants for spontaneous and forced magnetostrictions, of different magnitudes, are temperature dependent. Analysis of the pressure effect on the Curie temperature Tc and the spontaneous magnetic moment M shows that the linear relation between them, , is generally violated.

Transport properties of evaporated versus sputtered amorphous germanium films

The electrical d.c. conductivity and the thermoelectric power of evaporated amorphous Ge films prepared under various conditions were thoroughly measured over a wide temperature range (50-600 K). The results are compared in detail to those of similar measurements on sputtered amorphous Ge films. The similarities between the transport properties of the two types of samples are emphasized and discussed. The discrepancies are tentatively attributed to the non-homogeneity of the different amorphous films.
Fostering Critical Writing Through Dialogic Teaching: A Critical Thinking Practice among Teachers and Students

Current trends in education reformed the classrooms as critical sites for promoting learners’ social identity, cognitive development, and critical skills. From this perspective, the classroom turned out to be an arena to raise students' critical consciousness to be the agent of change. In such a context, this paper examined (a) the extent to which implementing the principles of dialogic teaching (DT) can increase critical thinking (CT) mode of students’ writing, (b) the practicality of DT from EFL teachers’ perspective. To this end, a qualitative method was adopted and the data were collected from students’ dialogue journals (DJs) and teachers’ perceptions on a CT questionnaire (CTQ). Notably, students were invited to write DJs to reflect on the class discussion. To quantify how DJs contribute to students' CT practice, Ada's (1988) four critical literacy (CL) modes in writing was employed. Analysis followed Heigham and Croker’s (2009) guidelines for generating meaning from DJs. An iterative analysis led to the identification of codes from students’ excerpts. Next, a nationwide study was conducted to distribute CTQ among 200 EFL teachers to navigate their priority over the principles of DT. The results indicated that students' descriptive and personal mode of writing decreased in the last temporal session and it changed to be critical and creative mode. Although teachers were supportive of the principles, they reported implementing DT may not be practiced in reality due to some boundaries. The findings suggest that language policymakers and materials developers should move along with the new critical-oriented, self-directed learning and dialogic notion of teaching.
Job Satisfaction, Firm Performance and CSR

Purpose - The study proposes and empirically tests four hypotheses: the firm and CEO characteristics have a relationship with employees’ job satisfaction / the firm performance is correlated with job satisfaction/ the CSR rating is associated with employee satisfaction / the employee satisfaction is associated with CSR ratings. Design/methodology/approach - Hypotheses were all tested through both linear regression and logistic regression analyses, using data from Wharton Research Data Services (WRDS). Findings – The result of this study provides the evidence that the firm characteristics are important factors that affect employee satisfaction and job satisfaction is positively correlated with the firm performance. Moreover, when job satisfaction increases, the CSR rating will increase. However, when the CSR rating increases, the impact of job satisfaction depends on the variable we used to measure the job satisfaction. Practical implications – The finding of this paper can be used in human resources management and understanding the impact of CSR on employee satisfaction is relevant to corporate performance. Key word - Corporate social Responsibility Rating/ Employees’ benefits/ Firm Performance/ Job satisfaction
A Comparison of Selected Quality Attributes of Flours: Effects of Dry and Wet Grinding Methods

Studies were conducted on the selected quality attributes of rice flour obtained by dry and wet grinding methods. Raw and parboiled rice have been dry ground at a moisture content of 12%, while wet grinding is performed at 30%. The functional properties of ground samples and doughs made out of the flours were characterized. The damaged starch contents in the dry ground rice flour were 21.5 and 22.6% for raw and parboiled samples, respectively; whereas, these were only 8.7 and 9.5% for wet ground samples. The dry ground rice flour formed sticky dough having high stickiness values but it was less cohesive in nature compared to those of wet ground samples. The doughs made from wet ground rice were more adhesive than the dry ground samples; the former was suitable for forming extrusion processing for preparing various convenience foods like pasta and noodles.
Thermodynamic model for the description of smectic C* and smectic A–smectic C* phase transition properties

We construct a phenomenological model to describe the general features of chiral smectic C* (Sm C*) phase and Sm A–Sm C* phase transition properties of ferroelectric liquid crystals. The free-energy density of the system is expanded in terms of three degrees of freedom – tensor orientational order Q ij , scalar smectic order Ψ and polarization vector P and couplings between these order parameters. Since Q ij describes the tilt vector ξ, no term contains ξ. The values of Landau coefficients are determined by comparing with the experimental data of helical pitch, tilt angle and spontaneous polarization and introducing an empirical relation for the temperature variation of the modulus S of orientational order parameter Q ij . Taking these values we evaluate the tilt angle, spontaneous polarization and pitch of the Sm C* phase and the Sm A–Sm C* phase transition. It is found that the theoretical results agree very well with the experimental data of four ferroic mesogens.
Theoretical study of the pressure‐induced structural phase transition of ScSb and YSb

The equations of state and phase stability of ScSb and YSb were investigated via a first-principles theoretical calculation. For each compound we fixed the B1 (NaCl) structure as the ambient pressure phase and considered the B2 (CsCl) structure as a candidate for the high-pressure phases. We report the results of the structural and electronic properties of these compounds in the considered structures and the theoretical transition pressure. © 2004 Wiley Periodicals, Inc.

Oxygen–metal bonding in Ti-bearing compounds from O 1s spectra and ab initio full multiple-scattering calculations

The O K-edge spectra of a series of Ti-bearing compounds with Ti in different structural and chemical environments have been measured using electron energy-loss spectroscopy and analyzed using ab initio full multiple-scattering (MS) calculations. The near-edge structures arise mainly from covalency by direct and/or indirect interaction between O and metal atoms and between O and Si atoms. The coordination number of the cation and the site symmetry also influence the spectral shape and structures. Using different size clusters around the excited atom in the full MS simulation, it is possible to interpret and assign the features present in the spectra of each compound to its specific atomic arrangement and electronic structure.
Disclosure Descriptors: Helping Investors Process Complex Accounting Estimates by Using Short Identical Descriptors

Companies can use either identical or different descriptors to refer to the same item throughout their disclosures, and such descriptors can vary in length. We conduct three experiments in the setting of complex accounting estimate disclosures to examine how descriptor length and descriptor identicalness affect investors’ information processing and their investment judgments. We manipulate descriptor length (short versus long) in Experiment 1 and descriptor identicalness (identical versus non-identical) in Experiments 2 and 3. We also manipulate, in all experiments, whether managers’ estimate choices are consistent or inconsistent with their incentives to boost reported earnings. Consistent with our predictions, we find descriptor length affects information acquisition and descriptor identicalness affects information integration. Consequently, only when managers use short and identical descriptors, do investors assess lower credibility and indicate lower investment willingness for estimate choices that are incentive consistent versus inconsistent. Our study provides important insights to accounting researchers, practitioners, and regulators.

However, transition from the traditional, in-person, learning to distance learning in the Ukrainian Medical Stomatological Academy during the COVID-19 pandemic was successful
CORPORATE POLITICAL CONNECTION AND AUDIT QUALITY

Abstract Indonesia offers attractive conditions to explore research on political connections, be­cause Indonesia is a developing market country with a history of strong political connec­tions in business. This study aims to investigate how the effect of the political connections held by board of commissioners and directors in the company on auditor quality and how earnings management moderate political connections and audit quality. This study used a sample of all companies from all sectors listed on the Indonesia Stock Exchange (IDX) in 2015-2017 except financial and insurance industry companies, thus a sample of 1213 firm-years was obtained. The analysis technique used is logistic regression analysis. The results revealed that companies with board of commissioners and directors who are politically connected have a positive and significant effect on auditor quality, it means that compa­nies with political connections tend to choose industry specialist auditors as the company's external auditors. The results also revealed that earnings management does not moderate the effect of corporate political connections on audit quality. This research provides new insights about the use of political connections in the business environment especially in audit quality decisions in Indonesia.
Interaction between glycine and Na-, Ca- and Cu- rich smectites

Abstract The interactions between glycine and two Na-, Ca- and Cu-exchanged smectites with different layer-charge location were studied. The sorption of glycine depends on the nature of the interlayer cations (Ca < Na < Cu), and on the type of smectite. Sequential extraction procedures were carried out in order to test the possibility of removing metals and/or glycine from the smectite interlayer. By the end of the treatments, the release of the amino acid from the substrates, with the exception of Cu-rich smectite, was virtually complete. The thermal curves of glycine-smectites confirm the stronger bonding of the amino acid with Cu-exchanged samples, and FTIR spectra indicate that glycine is mainly sorbed in the zwitterionic form. The data obtained suggest that in investigations into mechanisms of the binding of metals by minerals and their subsequent mobilization, amino acids merit close attention.
Teacher’s belief and its implication on integrating CALL

These days, the development of science and technology achieved has contributed to the advance in language teaching and learning. Nowadays, language teachers utilize computer and internet with their software and facilities for the purpose of teaching and learning activities in the classrooms. The use of computer assisted language learning (CALL) for language teaching and learning is not only at formal school such as elementary school, high school and university, but it is also used at informal school such as Sanggar Kegiatan Belajar (SKB). Therefore, this study aims to investigate teacher’s belief and its implication on integrating CALL in English class at SKB (Sanggar Kegiatan Belajar). For reaching the aims, a qualitative method is conducted towards the participant who has used CALL for language teaching and learning at SKB. The participant is purposively selected in order to get sufficient data of this research. The questionnaire, interview and classroom observation are used for collecting data. The result of this study shows that the teacher has positive belief towards CALL integration in English teaching and learning process. Besides, the participant also implies the CALL integration by explaining materials through Power Point and You Tube, giving quiz and homework through Google form. Thus, the teacher’s beliefs has implicated in the English teaching and learning at Sanggar Kegiatan Belajar and CALL is useful for English teaching and learning process at Sanggar Kegiatan Belajar.
