The Impact of Online Reviews on Brand Equity

The goal of this research is to see how online consumer reviews affect brand equity. Customers of Jordanian online clothing stores make up the study population. Due to the difficulty of reaching all members of the population, an appropriate sampling approach was used, which is often used in research conditions. Appropriate sampling is a non-random sampling method that uses people who are easily accessible. A structured online survey was used to gather primary data. This survey was conducted among Jordanian customers of online clothes retailers. Customers were thus encouraged to take part in the survey by text messages, official websites, and social media channels. The research hypotheses were tested using structural equation modeling. The study results showed that the majority of online review dimensions had an impact on brand equity except for reviews time. However, social impact had the highest impact on brand equity. According to the study’s conclusions, marketers must connect with internet marketing methods, particularly social media, and include them into their marketing strategy

Integration of Supply Chains and Operational Performance: The Moderating Effects of Knowledge Management

Supply chain integration (SCI) is a strategic process management technique that may be used to boost an organizations performance and thereby gain a competitive edge. The purpose of this paper is to demonstrate both the direct effect of (SCI) on manufacturing firms operational performance and the moderating effect of knowledge management (KM) on the relationship between supplier integration (SI), customer integration (CI), internal integration (II), and operational performance (OP). The study analyzed survey data from 277 Jordanian manufacturing and industrial businesses using the PLS–Structural Equation method. According to the data, (CI), (II), and (SI) are all positively and significantly associated with operational success. (CI), (II), and (SI) all have a strong and beneficial moderate relationship with (OP). There is, however, no connection between (KM) and (OP). Furthermore, further research may be conducted to assess the applicability of the findings from this study to other populations of varied sizes in other countries. A long-term study that tracks the growth of different measures might provide further insight on the relationship between SCI and OP

Elective Cancer Surgery in COVID-19-Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study.

PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Abundant closed-form solitons for time-fractional integro–differential equation in fluid dynamics

In this paper, with the aid of the Mathematica package, several classes of exact analytical solutions for the time-fractional (2 + 1)-dimensional Ito equation are obtained. To analytically tackle the above equation, the Kudryashov simple equation approach and its modified form are applied. Rational, exponential-rational, periodic, and hyperbolic functions with a number of free parameters were represented by the obtained soliton solutions. Graphical illustrations with special choices of free constants and different fractional orders are included for certain acquired solutions. Both approaches include the efficiency, applicability and easy handling of the solution mechanism for nonlinear evolution equations that occur in the various real-life problems

In-situ investigation of water distribution in polymer electrolyte membrane fuel cells using high-resolution neutron tomography with 6.5 µm pixel size

In this feasibility study, high-resolution neutron tomography is used to investigate the water distribution in polymer electrolyte membrane fuel cells (PEMFCs). Two PEMFCs were built up with two different gas diffusion layers (GDLs) namely Sigracet® SGL-25BC and Freudenberg H14C10, respectively. High-resolution neutron tomography has the ability to display the water distribution in the flow field channels and the GDLs, with very high accuracy. Here, we found that the water distribution in the cell equipped with the Freudenberg H14C10 material was much more homogenous compared to the cell with the SGL-25BC material

Prevalence of Dental Fluorosis among Southern Jordanian Population

Introduction. Jordan is one of the Middle Eastern countries that is classified as a poor water resource country. People in Jordan consume any available water. In the south of Jordan, water resources are limited. The drinking water contains high levels of fluoride, which in turn leads to augmented danger of both skeletal and dental fluorosis. Aims. This study is focused on evaluating the pervasiveness of dental fluorosis among patients of Karak City and assessing the degree and distribution of fluorosis. Materials and Methods. This research focuses on 2,512 patients ranging from 12 to 52 years old seeking dental treatment in the Dental Department at “Prince Ali ben Al Houssin Hospital” in Karak City. Dental fluorosis status was assessed by using Modified Dean’s Fluorosis Index.” The data collected were subjected to statistical analysis. Results. The dental fluorosis prevalence within our sample was 39.9% in Karak City. Females were more influenced than males, and fluorosis was detected more often in those who drank tap water and was more common in a very mild and localized form. Conclusion. Fluorosis necessitates constant observation, and future study in terms of the intake in Jordan is recommended in terms of all sources. It would not be too soon to note that the supply of drinking water needs to be changed in South Jordan
