The new game of online marketing: How social media influencers drive online repurchase intention through brand trust and customer brand engagement

Purpose: This study examines the impact of social media influencers (SMIs) on online repurchase intentions through brand trust and customer engagement in the cosmetics sector.Design/methodology/approach: The study framework and hypotheses in this paper were tested using a questionnaire survey approach, with the consumer as the unit of analysis. The study’s main target was individuals who purchase cosmetics products through social media platforms. Questionnaire items were created using a measurement scale employed in an earlier study. A Likert scale of seven points, ranging from 1 to 7, was used to grade the questionnaire items. Responses ranged from strong disagreement to strong agreement.Findings: In general, this study revealed that social media influencers have a significant positive direct impact on brand trust, customer brand engagement, and online repurchase intentions. Moreover, social media influencers were the most vital determinant of online repurchase intention, followed by brand trust and customer brand engagement. Moreover, customer brand engagement had a significant positive impact on brand trust. Additionally, brand trust and customer brand engagement impacted significantly and positively on online repurchase intention. The mediation analysis results found that customer brand engagement did not mediate the positive impact of social media influencers on online repurchase intention. Furthermore, it was found that brand trust mediated the positive impact of social media influencers on online repurchase intentions. This study is among the first to offer empirical evidence to demonstrate that social media influencers act as a route to online repurchase intention through brand trust and customer brand engagement.Research limitations/implications: This study has several limitations. The first one is that it was only conducted in one country. Using samples from a single country (Jordan) may produce culture-specific findings that are difficult to generalise across other settings. The second limitation of this study is related to the target population. In this study, researchers surveyed individuals who purchased cosmetics products through social media platforms.Practical implications: As the use of social media rises, social media influencers have an ever-greater impact on customers' online purchase and repurchase intentions, as customers deem influencers to be ideal role models they aim to imitate.Originality/value: The study is highly valuable for marketing strategies, as social media influencers have a powerful impact on effective marketing strategies.
Vulnerability and seismic risk assessment of buildings following the 1989 Newcastle, Australia earthquake

Ten days after the Newcastle, Australia earthquake of 28 December, 1989, the UK-based Earthquake Engineering Field Investigation Team (EEFIT) mounted a five day mission to the affected area. This paper presents the findings of the EEFIT investigation and subsequent follow up studies in relation to the extent of building damage and its distribution within the City of Newcastle and the surrounding urban area. Results are based on both detailed street surveys and general damage surveys, the former carried out in two areas, namely the heavily damaged suburban district of Hamilton (3km west of the city centre) and the Newcastle central business district. The findings of these surveys have provided valuable information on the vulnerability of building stock of types common to other parts of Australia, the UK and elsewhere, and hence form an important database for the accurate assessment of seismic risk to buildings in regions of low seismicity. This information will assist the development of realistic, economical seismic code provisions for building design and construction in low-risk areas. An important feature arising from the surveys and subsequent analytical studies of site response in the heavily damaged districts within the Hunter River alluvial basin is that, contrary to reports published by the Institution of Engineers, Australia amongst others, the areas of deep alluvial soil and fill do not correlate strongly with the more heavily damaged districts determined from post-earthquake assessments. Hence, suggestions that this form of site soil amplification effect played a major part in the distribution and extent of heavy damage in this earthquake are somewhat misleading for the future development of planning and design regulations. Furthermore, the results of site response analyses show that it is more likely to be the shallower soils near the border of the alluvial basin which tend to amplify bedrock ground motions generated by this type of earthquake.
Research Advances on Swine Acute Diarrhea Syndrome Coronavirus

Simple Summary Swine acute diarrhea syndrome coronavirus is an emerging enteropathogenic coronavirus with high lethality in lactating piglets and strong cross-species transmission ability. As it is a new threat to the swine industry, research and understanding of this virus are still in the early stages. There are currently no commercially available vaccines that prevent swine acute diarrhea syndrome coronavirus (SADS-CoV). In this review, we systematically analyzed the structural components of the virus, input and possible modes of transmission, and the cross-species transmissibility of the virus to characterize its risk level. We also summarized host-dependent factors in the virus infection process, as well as the viral regulation of host cell life processes. Finally, we discussed preventive and therapeutic measures that can be adopted in the future. Through this review, we aim to contribute to a better understanding of this porcine enterovirus and to subsequent research. Abstract Swine acute diarrhea syndrome coronavirus (SADS-CoV) is a virulent pathogen that causes acute diarrhea in piglets. The virus was first discovered in Guangdong Province, China, in 2017 and has since emerged in Jiangxi, Fujian, and Guangxi Provinces. The outbreak exhibited a localized and sporadic pattern, with no discernable temporal continuity. The virus can infect human progenitor cells and demonstrates considerable potential for cross-species transmission, representing a potential risk for zoonotic transmission. Therefore, continuous surveillance of and comprehensive research on SADS-CoV are imperative. This review provides an overview of the temporal and evolutionary features of SADS-CoV outbreaks, focusing on the structural characteristics of the virus, which serve as the basis for discussing its potential for interspecies transmission. Additionally, the review summarizes virus–host interactions, including the effects on host cells, as well as apoptotic and autophagic behaviors, and discusses prevention and treatment modalities for this viral infection.
Dispersal and other inter-group movements in badgers, Meles meles

Investigated dispersal and other movements of badgers between social groups in a high density badger population in Sussex, southern England, during the period November 1988 to October 1993. Fourteen badgers (10 female, 4 male) were radio-collared, tracked and observed during nocturnal ranging. Daily sleeping locations of collared badgers were also recorded for a 2-year period. In addition bait-marking was carried out twice annually to determine territory boundaries. Twenty-eight movements between groups were recorded, including 7 permanent group changes, one temporary group change and 20 visits of shorter duration. All of the adult badgers that permanently changed groups were mature females
The Role of Magnetic Resonance Imaging in Pre-operative Assessment of Anorectal Fistula With Surgical Correlation

Background Anorectal fistulas are chronic inflammations of peri-anal tissues that form a connection between the perineal skin and the anal canal. Accurate preoperative evaluation of the main fistula's trajectory and pelvic tissues is essential for effective surgical treatment of anal fistulas. The inability to detect concealed lesions may result in the recurrence of fistulas and the conversion of a simple fistula into a complex fistula. Magnetic resonance imaging (MRI) imaging can detect concealed pathways and abscesses, thereby exposing the intricate connection between the fistula and anal-sphincter complex. This data serves as a roadmap for making surgical decisions, thereby reducing the likelihood of illness recurrence and complications after surgery. Aim To evaluate the role of MRI in pre-operative assessment of an anorectal fistula, compare its findings with surgical results. Materials and methods The research was conducted at the Radiology Department, Apollo Hospital, Hyderabad. It was a prospective observational study. IBM SPSS Statistics for Windows, Version 17 (released 2008; IBM Corp., Armonk, New York, United States) was utilized for data analysis. The mean and standard deviation were computed. We further applied appropriate statistical tests to determine the significance of MRI features with pre-operative findings. Results MRI accurately detects features like abscesses (sensitivity-100%, specificity-97.06%), secondary tracts of the fistula (sensitivity-93.55%, specificity-94.12%), horseshoe appearance, and supralevator extension (sensitivity-100%, specificity-97.50%, and 97.62%, respectively). Conclusion When comparing our results with intraoperative findings, MRI showed high sensitivity and specificity in detecting abscesses, secondary tracts, horseshoe appearances, and supralevator extensions. Our findings suggest that MRI can offer anatomical and pathological information for the pre-operative care and surgical planning of perianal fistulas.

Reporting of social determinants of health in randomized controlled trials conducted in the pediatric intensive care unit

Introduction The influence of social determinants of health (SDOH) on access to care and outcomes for critically ill children remains an understudied area with a paucity of high-quality data. Recent publications have highlighted the importance of incorporating SDOH considerations into research but the frequency with which this occurs in pediatric intensive care unit (PICU) research is unclear. Our objective was to determine the frequency and categories of SDOH variables reported and how these variables were defined in published PICU randomized controlled trials (RCTs). Methods We searched Medline, Embase, Lilacs, and Central from inception to Dec 2022. Inclusion criteria were randomized controlled trials of any intervention on children or their families in a PICU. Data related to study demographics and nine WHO SDOH categories were extracted, and descriptive statistics and qualitative data generated. Results 586 unique RCTs were included. Studies had a median sample size of 60 patients (IQR 40-106) with 73.0% of studies including ≤100 patients and 41.1% including ≤50 patients. A total of 181 (181/586, 30.9%) studies reported ≥1 SDOH variable of which 163 (163/586, 27.8%) reported them by randomization group. The most frequently reported categories were food insecurity (100/586, 17.1%) and social inclusion and non-discrimination (73/586, 12.5%). Twenty-five of 57 studies (43.9%) investigating feeding or nutrition and 11 of 82 (13.4%) assessing mechanical ventilation reported baseline nutritional assessments. Forty-one studies investigated interventions in children with asthma or bronchiolitis of which six reported on smoking in the home (6/41, 14.6%). Discussion Reporting of relevant SDOH variables occurs infrequently in PICU RCTs. In addition, when available, categorizations and definitions of SDOH vary considerably between studies. Standardization of SDOH variable collection along with consistent minimal reporting requirements for PICU RCT publications is needed.
A 3D regional crustal model of the NE Atlantic based on seismic and gravity data

Abstract We present a 3D regional crustal model for the North Atlantic, which is based on the integration of seismic constraints and gravity data. The model addresses the crustal thickness geometry, and includes information on sedimentary thickness, the presence of high-velocity zones in the lower crust, and information on the crustal density distribution in the continental and oceanic domains. Using an iterative forward- and inverse-modelling approach, we adhere to the seismic constraints within their uncertainty, but manage to enhance the crustal geometry in areas where seismic data are sparse or absent. A number of basins are resolved with more detail. Recently released seismic reflection data beneath the NE Greenland Shelf allowed for a major improvement of the crustal thickness estimates. Estimated Moho depths beneath the basins there vary between 15 and 25 km, which is compatible with the conjugate Norwegian margin. A major lower-crustal seismic velocity anomaly in the vicinity of the Greenland–Iceland–Faroe Ridge complex is supported by density modelling. We discuss the validity and uncertainties of our model assumptions and discuss the correlation with the main structural elements of the North Atlantic.
Polarimetric Radar for Automotive Applications

Current automotive radar sensors prove to be a weather robust and low-cost solution, but are suffering from low resolution and are not capable of classifying detected targets. However, for future applications like autonomous driving, such features are becoming ever increasingly important. On the basis of successful state-of-the-art applications, this work presents the first in-depth analysis and ground-breaking, novel results of polarimetric millimeter wave radars for automotive applications.
The Role of an Instructor’s Asynchronous Feedback in Promoting Students’ Interaction and Text Revisions

This study focused on teacher asynchronous feedback and how it engaged 15 English as Foreign language (EFL) learners in revising their writing. The data was collected from (1) the teacher’s feedback, (2) students’ responses and, (3) students’ drafts of writing. The data analysis showed that the teacher provided a number of 832 items of feedback which were categorized into “question” as the most dominating category, followed by “statement”, “suggestion”, “directive” and “correction”. Three hundred and eighty (380;46%) of the feedback items were direct, while 452 (54%) were indirect. The feedback focused on content, organization, vocabulary, grammar, mechanics and more general/not specific comments. Teacher’s feedback (1) engaged the learners in text revisions (overall=1102 comments), (2) stimulated their responses (overall=1032 comments) and (3) extended their online asynchronous interactions. Of the total amount of text revisions (1102), 362 (33%) were made based on the teacher’s direct feedback, and 427 (38%) of them were based on the teacher’s indirect feedback, while 313 (29%) were based on peers’ and self-corrections. The learners revised their writing in terms of content, organization, vocabulary, grammar and mechanics. The findings have implications for teacher interactive feedback practices in writing and the role of asynchronous tools in facilitating such practices.
A new approach for atmospheric turbulence removal using low-rank matrix factorization

In this article, a novel method for removing atmospheric turbulence from a sequence of turbulent images and restoring a high-quality image is presented. Turbulence is modeled using two factors: the geometric transformation of pixel locations represents the distortion, and the varying pixel brightness represents spatiotemporal varying blur. The main framework of the proposed method involves the utilization of low-rank matrix factorization, which achieves the modeling of both the geometric transformation of pixels and the spatiotemporal varying blur through an iterative process. In the proposed method, the initial step involves the selection of a subset of images using the random sample consensus method. Subsequently, estimation of the mixture of Gaussian noise parameters takes place. Following this, a window is chosen around each pixel based on the entropy of the surrounding region. Within this window, the transformation matrix is locally estimated. Lastly, by considering both the noise and the estimated geometric transformations of the selected images, an estimation of a low-rank matrix is conducted. This estimation process leads to the production of a turbulence-free image. The experimental results were obtained from both real and simulated datasets. These results demonstrated the efficacy of the proposed method in mitigating substantial geometrical distortions. Furthermore, the method showcased the ability to improve spatiotemporal varying blur and effectively restore the details present in the original image.
Nurses’ knowledge, attitudes, and practices about rehabilitation of patients after heart valve surgery in Namibia

Background A cardiac rehabilitation programme is a medically supervised intervention to assist patients in recovery after heart surgeries and to prevent potential complications. Nurses should have the knowledge, a positive attitudes, and good practices to improve patient quality of life during the recovery process. Aim This study aimed to describe the knowledge, attitudes, and practices of the nurses regarding cardiac rehabilitation for patients after heart valve surgery. Setting The study setting was Windhoek Central Hospital, Cardiac Unit, in Windhoek, Namibia. Methods A quantitative and descriptive research design was used for convenient non-probability sampling of (N = 23) nurses who consented to participate in the study. Data were collected through self-administered questionnaires and analyzed using SPSS Version 26. Descriptive statistics were used and Fischer’s Exact test for associations of variables was performed. Results The study results showed a high level of knowledge, good attitudes, and poor to fair practices toward cardiac rehabilitation. However, the respondents demonstrate a lack of knowledge about the indications, and benefits of cardiac rehabilitation, negative attitudes regarding counselling of patients on sexual activities, and poor practice regarding exercises and counseling of patients and caregivers on cardiac rehabilitation. Furthermore, there is a positive relationship between the respondents’ older age, senior rank, and having been trained I cardiac conditions and their knowledge, attitudes and practices regarding some core components of cardiac rehabilitation with P-value < 0.050. Conclusion There is a need for a cardiac rehabilitation programme to improve nurses’ attitudes and practices toward cardiac rehabilitation. Contribution Understanding the gap in knowledge, attitudes, and practices among the nurses regarding cardiac rehabilitation would guide the Ministry of Health and Social Services (MoHSS) in the implementation of the cardiac rehabilitation for patients after heart valve surgery.
The wave‐driven current in coastal canopies

Wave-driven flows over canopies of aquatic vegetation (such as seagrass) are characterized by the generation of a strong, shoreward mean current near the top of the canopy. This shoreward drift, which is observed to be up to 75% of the RMS above-canopy orbital velocity, can have a significant impact on residence times within coastal canopies. There have been limited observations of this current and an accurate formulation of its magnitude is still lacking. Accordingly, this study aims to develop a practical relationship to describe the strength of this current as a function of both wave and canopy characteristics. A simple model for the Lagrangian drift velocity indicates that the magnitude of the wave-driven current increases with the above-canopy oscillatory velocity, the vertical orbital excursion at the top of the canopy and the canopy density. An extensive laboratory study, using both rigid and (dynamically-scaled) flexible model vegetation, was carried out to evaluate the proposed model. Experimental results reveal a strong agreement between predicted and measured current velocities over a wide and realistic range of canopy and wave conditions. The validity of this model is also confirmed through available field measurements. Characterization of this wave-induced mean current will allow an enhanced capacity for predicting residence time, and thus key ecological processes, in coastal canopies.

Species-level Compensatory Responses Buffer Drought and Nitrogen Eutrophication Impacts on Plant-Arthropod Interactions in Species-Rich Grasslands

SPECIES-LEVEL COMPENSATORY RESPONSES BUFFER DROUGHT AND NITROGEN EUTROPHICATION IMPACTS ON PLANT-ARTHROPOD INTERACTIONS IN SPECIES-RICH GRASSLANDS Morgan J. Randall Advisor: University of Guelph, 2015 Professor A. S. MacDougall How drought and nitrogen deposition impact plant-arthropod dynamics is unclear due to interactions between water and nitrogen availability and plant quality for herbivores. Drought and eutrophication can increase plant quality (i.e., foliar nitrogen), the former doing so via physiological changes. Alternatively, drought may decrease plant quality by reducing ion transport and turgor. Re-occurrence of rainfall post-drought may result in the greatest plant quality by restoring ion transport and turgor. We employed a full factorial experiment in an old field and a tallgrass prairie to quantify interactions among drought, drought followed by a water pulse, and nitrogen addition on plants (biomass, cover, quality) and arthropods (herbivory, abundance, diversity). Community-level drought effects on plants were minor, explained by species-level compensation. Nitrogen addition increased biomass and foliar nitrogen, but not herbivory. Rather, arthropod-based responses were explained by grassland type. Our work demonstrates grassland plant-arthropod dynamics can be resistant to short-term drought and eutrophication.
Environmental Challenges in China POLYBROMINATED DIPHENYL ETHERS, DECHLORANE PLUS, AND POLYCHLORINATED BIPHENYLS IN TREE BARK NEAR THE UPPER YELLOW RIVER, CHINA

Willow tree bark samples from urban and rural sites in Inner Mongolia, Ningxia Province, and Gansu Province, in the Yellow Riverbasin,wereanalyzedforpolybrominateddiphenylethers(PBDEs),dechloraneplus(DP),anddioxin-likepolychlorinatedbiphenyls (DL-PCBs) to compare their relative levels in air in these areas (i.e., treating bark as a passive air sampler). No difference was found betweenthe pollutant concentrations inSalix matsudanaandSalix babylonicabarksamples. Themean concentrations of thetotal PBDEs, DP, and total DL-PCBs were 13 000 � 6400, 46 � 44, and 26 � 17pg/g dry weight, respectively, with urban samples containing much higher concentrations (19 000 � 5700pg/g, 51 � 27pg/g, and 37 � 29pg/g dry wt in PBDEs, DP, and DL-PCBs, respectively) than rural samples (10 000 � 5200pg/g, 45 � 53pg/g, 22 � 9pg/g dry wt). A strong positive correlation between PBDEs and DP was found in all of the samples (r ¼0.712, p ¼0.006), but correlations between PCBs and the other pollutants were only found in the rural samples. The total DL-PCB concentration in the tree bark correlated with population density. Environ Toxicol Chem 2014;9999:1-7. # 2014 SETAC
