The Relationship

Drawing upon the heuristic–systematic model (HSM) and considering the readers’ perspective, this study predicts that readers’ involvement and homophily between the reader and the review author (source) moderate the relationships between the credibility perception of online reviews and its antecedent factors. To test our hypotheses, we performed a user study on the Amazon Mechanical Turk platform. The results show that reader’s involvement moderates source credibility, internal consistency, review objectivity, and review sidedness on review credibility. In addition, homophily between the reader and the source also moderates the relationship between review credibility and its source. Our study contributes to information processing literature, especially in the context of online reviews, and suggests a better classification of the attributes related to online reviews using the HSM. Besides, it helps e-commerce platforms to customize online reviews for each reader to satisfy their information need and help them to make a better purchasing decision.

The aim of the work is to find relevant indicators for assessing the relationship between investments in fixed assets in agriculture, gross output of the industry, and agricultural exports using tools for modeling the impact of innovation and investment development on increasing production and export potential in the context of the formation of an export-oriented agricultural economy. The modeling methodology and the proposed estimating and forecasting tools for diagnosing and monitoring the state of sectoral and regional innovative agricultural systems are used to analyze the relationship between investments in fixed assets in agriculture, gross output of the industry, and agricultural exports based on the construction of the classification of Russian regions by factors that aggregate these features to diagnose incongruence problems and to improve institutional management in regional innovative export-oriented agrosystems. Based on the results of the factor analysis application, an underestimated role of indicators of investment in agriculture, the intensity and efficiency of agricultural production, were established. Based on the results of the cluster analysis, the established five groups of regions were identified, with significant differences in the level of investment in agriculture, the volume of production of the main types of agricultural products, and the export and exported food. The research results are of practical value for use in improving institutional management when planning reforms and transformations of regional innovative agrosystems.

The Empirical Analysis

When studying the impact of online reviews on product sales, previous scholars have usually assumed that every review for a product has the same probability of being viewed by consumers. However, decision-making and information processing theories underline that the accessibility of information plays a role in consumer decision-making. We incorporate the notion of review visibility to study the relationship between online reviews and product sales, which is proxied by sales rank information, studying three different cases: (1) when every online review is assumed to have the same probability of being viewed; (2) when we assume that consumers sort online reviews by the most helpful mechanism; and (3) when we assume that consumers sort online reviews by the most recent mechanism. Review non-textual and textual variables are analyzed. The empirical analysis is conducted using a panel of 119 cosmetic products over a period of nine weeks. Using the system generalized method of moments (system GMM) method for dynamic models of panel data, our findings reveal that review variables influence product sales, but the magnitude, and even the direction of the effect, vary amongst visibility cases. Overall, the characteristics of the most helpful reviews have a higher impact on sales.

The Relationship

The question of whether virtual quantum particles exist is considered here in light of previous critical analysis and under the assumption that there are particles in the world as described by quantum field theory. The relationship of the classification of particles to quantum-field-theoretic calculations and the diagrammatic aids that are often used in them is clarified. It is pointed out that the distinction between virtual particles and others and, therefore, judgments regarding their reality have been made on basis of these methods rather than on their physical characteristics. As such, it has obscured the question of their existence. It is here argued that the most influential arguments against the existence of virtual particles but not other particles fail because they either are arguments against the existence of particles in general rather than virtual particles per se, or are dependent on the imposition of classical intuitions on quantum systems, or are simply beside the point. Several reasons are then provided for considering virtual particles real, such as their descriptive, explanatory, and predictive value, and a clearer characterization of virtuality—one in terms of intermediate states—that also applies beyond perturbation theory is provided. It is also pointed out that in the role of force mediators, they serve to preclude action-at-a-distance between interacting particles. For these reasons, it is concluded that virtual particles are as real as other quantum particles.

Moderating Role

Contrasting findings about the role of extremely negative ratings (ENRR) are found in the literature, thus suggesting that not all ENRR are perceived as helpful by consumers. In order to shed light on the most helpful ENRR, we have drawn on negativity bias and signaling theory, and we have analyzed the moderating role of product quality signals in the relationship between ENRR and review helpfulness. The study is based on the analysis of 9,479 online reviews, posted on TripAdvisor.com, pertaining to 220 French hotels. The findings highlight that ENRR is judged as being more helpful when the hotel has been awarded a certificate of excellence, and when the average rating score and the hotel classification are higher. On the basis of these results, we recommend that managers of higher category hotels, with a certificate of excellence and with higher average score ratings, pay more attention to extremely negative judgments.

With an increase in e-commerce activity, online reviews have become a pertinent source of information for shoppers. Existing research is limited to examining select predictors of shoppers' intention to write reviews; however, there exists a gap in deciphering the role of review involvement in intention to write reviews. The present study pertains to the influence of the usefulness of site and product, and shoppers' satisfaction, and also on the intention to write reviews online. Besides this, the article also explores the moderating role of review involvement on the relationship between shopper satisfaction and their intention to post reviews. The study reveals a few interesting and counter-intuitive findings that add to literature and practice in understanding online review posting behaviour. Theoretical and managerial implications based on the findings are also presented.

Fatigue is a common and highly distressing symptom of cancer associated with reduced quality of life and considerable psychological and functional morbidity. The reported prevalence of cancer-related fatigue ranges from 4% to 91%, depending on the specific cancer population studied and the methods of assessment. Cancer-related fatigue has typically been underreported, underdiagnosed, and undertreated. Fatigue and depression may coexist in cancer patients, and considerable overlap of symptoms occurs. This is partly the reason for the interest in examining the role of psychotropic medications in treating fatigue. Clarifying the relationship between depression and fatigue is necessary to effectively evaluate and treat cancer-related fatigue. Even with International Classification of Diseases criteria, differentiating cancer-related fatigue is difficult. Psychotropic drugs that have been studied for cancer-related fatigue include psychostimulants, wakefulness-promoting agents, and anti-depressants. Methylphenidate has been studied most and seems to be effective and well tolerated despite common side effects. Some preliminary data support using modafinil in cancer-related fatigue with less concern about tolerance or dependence. Antidepressant studies have shown mixed results. Paroxetine seems to show benefit for fatigue primarily when it is a symptom of clinical depression. Bupropion, a norepinephrine/dopamine reuptake inhibitor, may have psychostimulant-like effects, and therefore may be more beneficial for treating fatigue. However, studies are currently limited. Randomized, placebo-controlled trials with specific agents are needed to further assess the efficacy and tolerability of psychotropic medications in the treatment of cancer-related fatigue.

The article reviews the definitions of the tutoring concept in preschoolers relationships. Can we qualify the relationships of preschool children in learning situations as tutoring? Or maybe a different name would be more suitable for them? Preschoolers are used to learning in a different way than adults and older children. They prefer learning mimicking or playing. They obtain knowldge occasionally an unintentionally. In turn, definitions of tutoring quite precisely contain formulated fortifications that a little child is not able to meet yet. Immaturity of the nervous system limit the level and length of attention span of little child and relatively small, compared to school children and adults number of social experiences can seriously hamper the classification of situations in which children learn from each other as tutoring. While the generally understood master-student relationship, associated with tutoring, is quite often noticeable during childhood collaboration and play in which one child can do more than the other, the more detailed assumptions of tutoring are not as accessible to the observer. For example, it is difficult to talk about the regularity or planned nature of children's relationships. The definition of tutoring also sets specific expectations regarding the teacher's skills, among which are: high interpersonal competences, commitment to the relationship with the mentee, professionalism and responsibility. From a preschool child who would play the role of a teacher, it is difficult to demand fluent speech, not to mention professionalism and regularity. A preschool child, who just start to learn numbers, is often unable to orient himself in time, which makes it difficult or even impossible to plan and systematize his activities. Little child needs adult help in this area.

Purpose Disaster information is an important resource for flood preparedness, however, the transition of information provision to preparedness and consequently to damage reduction is complex. The nature of complexity has made it imperative to provide context-specific evidence on how disaster information provision influences intentions to prepare for flood hazard. This paper seeks to investigate how message clarity and source credibility mediate and moderate the relationship between information sufficiency and intentions to prepare. This paper aims to provide valuable insights into the relationship between the major components of disaster communication and their influence on intentions to prepare. Design/methodology/approach The study used a cross-sectional survey design to test the relationship between information sufficiency, message clarity and source credibility. A total of 1,064 questionnaire surveys were conducted on a face-to-face basis. The data collection was done in one month with ten research assistants. Participants of the study were randomly selected from adults over 18-years old who have lived in the study areas for at least three years. Responses from participants were analysed using a structural equation modelling (SEM) technique and SPSS AMOS version 24 software. Findings Findings suggest that the information sufficiency-intentions to prepare relationship is enhanced when adequate disaster information communicated is clear and from a credible source. This implies that policymakers and risk communicators need to critically assess the clarity of disaster information content and the credibility of the source in the dissemination of information during the communication process. It also provides a better understanding of the factors that influence people’s intentions to prepare for flood hazards. Research limitations/implications This current study did not account for the specific nature or content of information necessary to increase message clarity and source credibility for disaster preparedness. In addition, the study did not cover the channels of communication ideal to stimulate people’s intentions to flood preparedness. Although these do not undermine the significance of the present study, they present entry points for further studies. In view of the on-going urbanisation dynamics and the complex socio-spatial patterns emerging in the Greater Accra Area, it is recommended that further studies explore the channels of communication that will suit the diverse socio-spatial profile of residents (e.g. age, location, ethnicity, etc.). Originality/value While a plethora of studies emphasize the role of source credibility, information sufficiency and message clarity towards disaster preparedness, there is at present little evidence on the mediating and moderating role of the communication variables. In this study, we propose and test the mediating and moderating role of message clarity and source credibility on the relationship between information sufficiency and intentions to prepare. The findings of this paper provide other incentives that encourage message audiences to take up precautionary measures towards flood hazards. In addition, with a view that people fail to prepare because of lack of sufficient information, the study findings suggest that the provision of sufficient information may enhance preparedness.

Purpose This paper aims to investigate whether a message from a brand with stronger brand equity generates more trust than a message from a brand with lower brand equity, and thus is more likely to encourage consumers to write online reviews. This paper also explores what happens when consumers become aware that brands are trying to persuade them to write a review. Design/methodology/approach Through three experimental studies, where participants were randomly assigned to a brand that has either a stronger or weaker brand equity, participants’ intention to write reviews was measured. Trust in the message was measured to study its mediating role, and persuasion knowledge of the participants was manipulated to investigate its moderating effect. Findings The findings confirm that consumers are more likely to write online reviews when a message comes from a brand that has stronger brand equity, trust in the message mediates the relationship between brand equity and consumer intention to write an online review, and persuasion knowledge has a differential effect on consumer intention to write reviews. Originality/value The study adds to the brand equity and online review literature by providing evidence that a higher level of consumer trust on brands that have stronger brand equity leads to an increased intention to write a review for the brand. It also shows that consumers’ awareness of the motive of the brand is more beneficial for brands with strong brand equity, contributing to persuasion knowledge literature.
