The Impact

With traffic increase in a wireless network beyond its capacity and as the number of connected devices continue to grow, the quality of service (QoS) degrades. In this paper we study the impact of mobility on throughput in the case of an infrastructure wireless network using IEEE 802.11 Wi-Fi standard. Since we found in the literature that the mobility of stations can have an impact on the quality of service, we try to remedy to this by implementing a new access category reserved for mobile stations. First we compare the throughput between static and mobile nodes, both connected to a QoS station. Then we propose our new model that consists of adding a new access category used by mobile nodes regardless of their traffic category. The study was made by simulating different scenarios using Network Simulator-3 (NS-3). We found that the throughput may vary depending on the simulation scenario. The simulation results show that with the proposed solution the mobile nodes can have a better throughput.

The Impact

Purpose This study seeks to analyze the influence of the consumer's perceived benefits deriving from two different promotional incentives offered via social media on the perceived quality of the heritage complex.Design/methodology/approach A quasi-experimental study was carried out among online users, implementing two different promotional stimuli. Facebook was selected as the social network through which the promotional incentives were offered in the experiment. The sample was obtained via a panel of Internet users provided by Sondea Internet SL.Findings The results showed that the benefits perceived by the tourists will depend on the sales promotion type offered. On the one hand, free VIP pass was found to be mostly related to hedonic benefits that positively affect perceived quality. On the other hand, 2 × 1 offer would be perceived as a utilitarian benefit and is likely to exert a fairly negative effect on perceived quality.Practical implications Tourism managers and practitioners are encouraged to analyze the characteristics of certain types of sales promotions, as each promotional incentive bears different values and associated benefits. The findings of this study suggest managers and practitioners to implement non-monetary promotions to enhance brand equity and perceived quality. Thus, it is paramount for the managers of cultural institutions and heritage sites to trust in sales promotions which can be very helpful if they are designed carefully.Originality/value This study pioneers the analysis of the impact of the benefits associated with different typologies of sales promotions on social networks on the perceived quality of a heritage site.

Abstract Study question Are there any differences relating to the perceived quality of life (QoL) and sexual satisfaction among infertile women? Summary answer There were no differences between women who already had a baby and those who did not relating to the perceived QoL and sexual satisfaction. What is known already Infertility is a medical disease with a high social component with a 16% prevalence. There have been many investigations regarding to the physical part of the infertility but the sexual and marital satisfaction has not been as intensively investigated. The importance of the psychological counseling in fertility treatments has already been proven, but the significance of sexual satisfaction on individual’s perception on QoL has not been as deeply studied. Study design, size, duration A transversal descriptive study was done. 313 heterosexual married women with fertility problems were recruited in collaboration with the Spanish patient association “Red Nacional de Infértiles”. The Fertility quality of life tool (FertiQoL) was selected to measure the perceived QoL and the Index of Sexual Satisfaction (ISS) was chosen to study the degree of sexual satisfaction. The data collection was made between January and February 2020 and all the information was gathered online. Participants/materials, setting, methods 313 women filled the questionnaire which had 4 different modules: A sociodemographic module (sex, age, studies, time trying to conceive, moment of treatment and offspring), two modules for each measurement instrument and a last module in which they could write their personal experiences regarding to the infertility journey. ANOVA and t-Student statistical analyses were done to compare the different independent variables. To see if FertiQoL could explain the sexual satisfaction a regression analysis was made. Main results and the role of chance To achieve 95% power (α = 0.05) and an effect size of 0.25, a minimum sample size of 210 was needed and a sample of 313 women was recruited. There were no statistical differences between women with previous offspring and those who did not in neither of the FertiQoL subscales (Emotional: 7,4 ± 3,884 vs. 7,34 ± 4,235; Mind/Body: 9,65 ± 5,098 vs. 8,66 ± 4,979; Relational: 16,88 ± 4,807 vs. 16,3 ± 4,956; Social: 10,52 ± 5,02 vs. 10,1 ± 4,801; Tolerability: 5,91 ± 4,114 vs. 6,65 ± 3,357; Environment: 12,71 ± 5,02 vs. 11,42 ± 4,963) nor in the ISS questionnaire (47,48 ± 6,488 vs. 47,22 ± 7,35). Regarding to the power of the FertiQoL instrument and the perceived QoL to predict the sexual satisfaction, the regression model showed that the sexual satisfaction could be explained in 26,3% of the cases by the relational and mind/body subscales of the FertiQol tool. This model showed the inherent relationship between marital and personal wellbeing in order to obtain a better sexual satisfaction. Limitations, reasons for caution As the study had a transversal design, no cause-effect relationships could be done. It would be desirable to establish a longitudinal study in order to determine a more accurate relationship between the studied variables. Wider implications of the findings: This study showed that the impact of infertility in women with secondary infertility diagnose could be at least as high as in women with primary infertility diagnose. FertiQoL would be a reasonable instrument to estimate the sexual satisfaction of infertile women. Sexology should be part of the infertility counselling programs.

The Impact

Market reaction to surprises in earnings announcements has long been used to measure the quality of the information content of the announcement, and studies have explored various factors affecting the response. This study adds to this body of research by factoring in the level of corporate social responsibility (CSR) exhibited by the firm and employs a relatively new measure of a company’s level of CSR, rankings published by JUST Capital. I hypothesize that financial information reported by higher ranked companies is weighed more heavily by investors than those reported by non-ranked or lower-ranked companies. Using earnings response coefficients as a measure of the perceived quality of the financial information reported by the firms, my results provide direct support of the hypothesis, indicating that the market reacts more strongly to earnings surprises for firms with high JUST rankings than for unranked firms or firms with lower rankings. This result contributes new insights into the impact of a firm’s CSR in terms of the perceived quality of a firm’s financial reporting.

Customer loyalty to a destination and accommodation services constitutes a frequent object of research; however, customer loyalty to travel agencies is rarely analyzed. The presented article is an attempt to fill in this research gap. Its purpose is to construct and verify the model covering the impact of the selected factors on the loyalty level of customers of travel agencies operating in Poland. The conceptualization of the loyalty model of travel agency customers (based on the European path-based EPSI model) proposed in the article was first used to illustrate the existing correlations in customer behavior to analyze and explain the development of the loyalty phenomenon vis-a-vis travel agency customers. The aforementioned assumptions—having applied the structural equation modelling (SEM)—were reflected in the development of the theoretical model of travel agencies customer loyalty, the empirical verification of which (N = 1151) allowed us to determine the impacts of selected factors (i.e., the perceived quality of the travel agency’s offers, its image and the satisfaction with its service buyers) on the loyalty level of travel agency customers. It has been shown that two major factors have positive impacts on the loyalty of travel agency customers: (i) the perceived quality of travel agency offers, and (ii) its image. Furthermore, the conducted analysis highlights the positive influence of the perceived value of travel agency offers on the loyalty of customers.
