Assessing the Effectiveness of Tourism Promotional Videos: Creativity, Emotional Impact, Perceived Quality, and Attitude Towards the Destination

Tourism promotional videos (TPVs) are widely used by destination management organizations (DMOs) in promotional campaigns. With the aim of opening new research perspectives in the field of tourism promotion, this article proposes a model for evaluating the effectiveness of TPVs—the Emovie model—conceptually anchored in studies on transformational and symbolic advertising. The model describes the interrelationship of four constructs: artistic value, positive emotional impact, perceived quality of the video, and perceived quality of the destination. The model was tested in three empirical studies carried out in parallel and using the same methodological procedures for quantitative analysis, applied to three samples totaling 674 individuals. The results show that the creativity and originality of TPVs elicit positive emotional reactions, resulting in favorable attitudes towards the message and the destination. This study is particularly important because it provides DMOs with a tool for evaluating the effectiveness of their promotional videos.

Quantitative and qualitative phytochemical analysis of ethanol leaf extract of Pleiocarpa mutica

This research project examined Pleiocarpa mutica leaf extract, extracted from ethanol using both quantitative and qualitative phytochemical analysis. Sourced is at Ugbene-Ajima in the Uzo-Uwani Local Government Area of Enugu State, Nigeria, where fresh Pleiocarpa mutica leaves were collected. After been gathered, the newly sprouted P. mutica leaves were cleaned. We then shade-dried the leaves until they were crispy, rotating them frequently to prevent them from rotting. A mechanical grinder was utilized to reduce the dried leaves to a powdered state while a maceration flask was used to macerate 1.5 kg of the known weight of the ground leaves in 10 liters of 100% ethanol. In using a muslin cloth, the mixture was filtered into a flask with a flat bottom after being left for 72 hours with irregular stirring. Quantitative phytochemical analysis procedures identified the specific concentration of a certain chemical constituent present in a plant sample using methods such as mass spectrometry, chromatography, and spectrophotometry. This makes it possible to determine the concentration of a component in the plant material. Qualitative phytochemical analysis techniques focus on identifying the presence or absence of several chemical groups in a plant sample. Discovering the existence of substances such as alkaloids, phenols, terpenoids, and flavonoids often requires a range of chemical analyses or the use of specific reagents. Thus, the standard quantitative and qualitative phytochemical analysis technique were used to investigate the chemical composition of plants and identify bioactive compounds that may offer nutritional, medicinal, or pharmacological advantages. Hence, it has been shown that the ethanol leaves extract of P. mutica contains various concentrations of phytochemical constituents, which might be responsible for its biological activities.

Analysis of University Students' Perspectives on Physical Activity and Mandatory Physical Education

The decline in physical activity levels during the transition from high school to college is evident, despite the known impact of youth and adolescent physical activity on later life. Observable trends reveal a decline in enthusiasm for sports activities and a notable decrease in motivation for engaging in physical activity. The college environment plays a pivotal role in shaping students' engagement with physical activity, presenting an opportunity to significantly enhance their quality of life. This study's primary objective is to analyse university students' attitudes toward physical activity and assess their satisfaction with compulsory physical education at Masaryk University, comparing results spanning nearly two decades. In adherence to contemporary research methodologies, a questionnaire survey combining standard quantitative and qualitative analysis procedures was conducted. The survey questions focused on examining various facets of physical activity, including volume, intensity, sports preferences, and attitudes toward mandatory physical education at Masaryk University in Brno. A total of 1,293 respondents (422 men and 871 women) with an average age of 20.7 years participated in the study. The findings underscore a notable inclination among almost 73% of students to welcome an extension of compulsory physical education to 2 or more semesters (currently set at 2 semesters at MU). Moreover, over 75% of students express contentment with the spectrum of mandatory sports activities offered in physical education. The study reveals a growing interest among students in individual physical activities and a burgeoning enthusiasm for unorganized sports. These outcomes furnish valuable insights into students' perceptions regarding the organization of physical and sports education activities within university settings.

Phoenix–A model-based human reliability analysis methodology: Data sources and quantitative analysis procedure

Human Reliability Analysis (HRA) has continuously evolved to adopt more advanced human error probability (HEP) quantification approaches. Despite several efforts and enhancements of HRA methods, many still present limitations. Phoenix HRA Methodology aims to overcome known issues by incorporating strong elements of current HRA good practices, leveraging lessons learned from empirical studies and existing and emerging HRA methods' features. Phoenix models performance influencing factors (PIFs) and their impact on failure modes through Bayesian Networks (BBNs). Despite increased use in HRA applications, the large amount of data BBNs may require is still challenging. Thus, to populate Phoenix BBNs, several data sources were combined, including other HRA methods, expert judgment, and operating experience. The paper discusses Phoenix's quantitative analysis process, the data sources used to estimate the BBN parameters, and the applied data aggregation method. It further provides the quantitative analysis procedure guide with the significant steps and sub-steps an HRA analyst requires to implement this Phoenix methodology phase. Furthermore, the method for mapping the data to Phoenix BBN parameters and for aggregating the data considering non-homogeneous data sources can be further used for other HRA methods that apply BBNs or other applications.

Bearings on Classroom Assessment Practices: From Perception to Practice

This study examines the assessment strategies and practices at Oran 2 University, Algeria. It attempts to explore the impact of assessment procedures on learners’ motivation and academic achievements. This research adopted a mixed-methods case study design wherein both quantitative and qualitative data collection and analysis procedures were used to explore tertiary teachers’ assessment strategies while assessing their learners’ competencies. A random sample of 30 tertiary teachers formed the target population during the first semester of the academic year 2022. Findings reveal that some teachers continue to rely on a limited set of assessment tools as the sole means of evaluation to meet the diverse needs of their learners. However, the study also highlights that teachers also showed a good understanding of the necessary knowledge and training required before implementing assessment tools to provide students with the necessary feedback. The results also indicate an essential need for in-service training, pedagogical support, and professional development to meet the challenges identified by teachers in adapting and maintaining effective assessment practices at all levels of tertiary education.

Robust parameter design of the measurement procedure for determining the chemical composition of copper alloys by X-ray fluorescence

A brief overview of contemporary methods for determining the chemical composition of copper alloys and the analytical control methods used is given. It has been shown that to obtain reliable and comparable results of measuring the mass fractions of copper alloys elements in wide ranges of values, the most suitable procedures are based on the X-ray fluorescence method, implemented using portable X-ray fluorescence spectrometers. In order to select the optimal values of the influencing quantities when determining the chemical composition of copper alloys, a robust parameter design of a quantitative chemical analysis procedure was carried out on the X-50 Mobile X-ray fluorescence spectrometer. The use of robust parameter design, as opposed to conducting a full factorial experiment when developing a measurement procedure, makes it possible to optimize measurement conditions and obtain results of the required accuracy with a limited number of experiments and a maximum number of control factors. An example of drawing up an experimental plan for the parameter design of this procedure is given and a statistical analysis of the measurement results is carried out. The optimal measurement conditions (influencing quantities) were analyzed and selected, under which the minimum error in the results of measuring the mass fraction of elements is ensured. The selection of optimal values of the influencing quantities based on the results of robust parameter design of the quantitative chemical analysis procedure made it possible to increase the accuracy of the results of determining the chemical composition of copper alloys and, as a consequence, the reliability of the results of product quality control at relatively low costs for its implementation. This approach can be recommended to analytical laboratories developing procedures of quantitative chemical analysis for metallurgical industry enterprises.

A Bogue approach applied to BOF slag

AbstractAn industrial by‐product of the steel industry called basic oxygen furnace (BOF) slag has recently undergone extensive research for high‐end applications outside of road load and landfill. In contrast to the Bogue methodology used with regular Portland cement, BOF slag lacks a quick and straightforward quantitative phase analysis procedure that would allow it to be employed as a high‐end raw material. The main phases of BOF slag (C2S, C2(A,F), Ff, RO‐Phase, and f‐C) can be calculated using the method presented in this paper based on chemical composition.

Unraveling the associations and causalities between glucose metabolism and multiple sleep traits.

The aim of our study is to estimate the associations and causalities of glucose metabolism traits of fasting blood glucose (FBG), fasting insulin (FINS), glycosylated hemoglobin (HbA1c), and 2-h glucose post-challenge (2hGlu) with sleep traits consisting of excessive daytime sleepiness (EDS), insomnia, and sleep duration. We employed standard quantitative analysis procedures to assess the associations between sleep traits and glucose metabolism. Moreover, we acquired published genome-wide association studies (GWAS) summary statistics for these traits and conducted Mendelian randomization (MR) analyses to estimate their causal directions and effects. Inverse variance weighting (IVW) was employed as the primary approach, followed by sensitivity analyses. A total of 116 studies with over 840,000 participants were included in the quantitative analysis. Our results revealed that participants with abnormal glucose metabolism had higher risks for EDS (OR [95% CI] = 1.37 [1.10,1.69]), insomnia (OR [95% CI] = 1.65 [1.24,2.20]), and both short and long sleep duration (OR [95% CI] = 1.35 [1.12,1.63]; OR [95% CI] = 1.38 [1.13,1.67] respectively). In addition, individuals with these sleep traits exhibited alterations in several glycemic traits compared with non-affected controls. In MR analysis, the primary analysis demonstrated causal effects of 2hGlu on risks of EDS (OR [95% CI] = 1.022 [1.002,1.042]) and insomnia (OR [95% CI] = 1.020[1.001,1.039]). Furthermore, FINS was associated with short sleep duration (OR [95% CI] = 1.043 [1.018,1.068]), which reversely presented a causal influence on HbA1c (β [95% CI] = 0.131 [0.022,0.239]). These results were confirmed by sensitivity analysis. Our results suggested mutual risk and causal associations between the sleep traits and glycemic traits, shedding new light on clinical strategies for preventing sleep disorders and regulating glucose metabolism. Future studies targeting these associations may hold a promising prospect for public health.

The Causal Associations of Altered Inflammatory Proteins with Sleep Duration, Insomnia and Daytime Sleepiness.

Growing evidence linked inflammation with sleep. This study aimed to evaluate the associations and causal effects of sleep traits including insomnia, excessive daytime sleepiness (EDS) and sleep duration (short:<7h; normal:7-9h; long:≥9h), with levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α) and interleukins. Standard procedures of quantitative analysis were applied to estimate the expression differences for each protein in compared groups. Then, a two-sample Mendelian randomization (MR) analysis was performed to explore their causal relationships with published GWAS summary statistics. The inverse-variance weighted (IVW) was used as the primary method, followed by several complementary approaches as sensitivity analyses. A total of 44 publications with 51879 participants were included in the quantitative analysis. Our results showed that the levels of CRP, IL-1β, IL-6 and TNF-α were higher from 0.36 to 0.58 (after standardization) in insomnia compared to controls, while there was no significant difference between participants with EDS and controls. Besides, there was a U/J-shaped expression of CRP and IL-6 with sleep durations. In MR analysis, the primary results demonstrated the causal effects of CRP on sleep duration (estimate:0.017; 95% CI, [0.003, 0.031]) and short sleep duration (estimate:-0.006; 95% CI, [-0.011, -0.001]). Also, IL-6 was found to be associated with long sleep duration (estimate:0.006; 95% CI, [0.000, 0.013]). These results were consistent in sensitivity analyses. There are high inflammatory profiles in insomnia and extremes of sleep duration. Meanwhile, elevated CRP and IL-6 have causal effects on longer sleep duration. Further studies can focus on related upstream and downstream mechanisms.

THE CONCEPTS OF «LEFT» AND «RIGHT» IN UKRAINIAN AND CHINESE FIXED PHRASES AND PROVERBS

The purpose of the article is to identify the cognitive bases of asymmetry in the use and perception of the concepts «left» and «right» // // 左 [zuǒ] and 右 [yòu] by Ukrainians and Chinese. These concepts function in the linguistic space of the world as one of the universal binary oppositions. This is most clearly expressed in constant word combinations and paremies. An attempt was made to determine the differences between the Ukrainian and Chinese language worldviews in situations where these concepts are present. Ukrainian and Chinese fixed word combinations and paremias with the semantically core words left and right // 左 and 右 were chosen as the object of study. The subject of the research is the identification of common and distinctive features in the perception of the Chinese and Ukrainians of the views and habits of using the concepts of «left» and «right» traditional in their national language worldviews. The procedures of semantic, connotative, phraseological, linguocultural, conceptual, cognitive, comparative and quantitative analysis, as well as the descriptive method, were used in the research process. The results of the research were the identification of selected Ukrainian and Chinese phraseological units that contain indicators of the concepts «left» and «right» // 左 [zuǒ] and 右 [yòu], their classification by discursive meaning, sphere of functioning, axiological characteristics, and a comparative analysis of the linguistic and cultural principles of use in the Ukrainian and Chinese languages was carried out. Conclusions are made regarding the asymmetry of the traditional perception and functioning of the conceptual meanings of left and right in compared languages

A quantitative analysis procedure for solving safety factor of tunnel preliminary support considering the equivalence between Hoek–Brown and Mohr–Coulomb criteria

There is a development trend from qualitative towards quantitative analysis for tunnel stability. The widely accepted convergence-confinement method (CCM) provides a quantitative framework for tunnel stability analysis, while the conventional CCM based on closed-form functions is essentially an ideal model without considering the tunnel section shape and rock weight in plastic zone. Herein, based on the CCM framework, a quantitative analysis procedure formulated through numerical simulations for more practical situations was systematically proposed to calculate the safety factor of spray-anchor support system in non-circular tunnel. Besides, similarities and differences between the most widely used Hoek-Brown (HB) and equivalent Mohr-Coulomb (EMC) criteria were considered for practical reference. The proposed method was utilized to conduct quantitative analysis of LDPs, mechanical responses of surrounding rock and safety factors for four typical tunnels, and the consistency between tunnels based on HB criterion (TBHBC) and EMC criterion (TBEMCC) was analyzed. The results indicated that the maximum radial convergence of LDP, plastic zone area, and safety factor of TBEMCC were 34.54%, 37.29%, and 47.71% lower than those of TBHBC respectively. The reasons for differences between results were revealed. The spatial effect induced by the face excavation of TBEMCC was weakened as compared to TBHBC, leading to a drop of LDP. Consequently, the safety factor was underestimated. The method systematically provided an effective tool for quantitative stability analysis and design optimization of support system for an underground excavation.

Early radial positional information in the cochlea is optimized by a precise linear BMP gradient and enhanced by SOX2

Positional information encoded in signaling molecules is essential for early patterning in the prosensory domain of the developing cochlea. The sensory epithelium, the organ of Corti, contains an exquisite repeating pattern of hair cells and supporting cells. This requires precision in the morphogen signals that set the initial radial compartment boundaries, but this has not been investigated. To measure gradient formation and morphogenetic precision in developing cochlea, we developed a quantitative image analysis procedure measuring SOX2 and pSMAD1/5/9 profiles in mouse embryos at embryonic day (E)12.5, E13.5, and E14.5. Intriguingly, we found that the pSMAD1/5/9 profile forms a linear gradient up to the medial ~ 75% of the PSD from the pSMAD1/5/9 peak in the lateral edge during E12.5 and E13.5. This is a surprising activity readout for a diffusive BMP4 ligand secreted from a tightly constrained lateral region since morphogens typically form exponential or power-law gradient shapes. This is meaningful for gradient interpretation because while linear profiles offer the theoretically highest information content and distributed precision for patterning, a linear morphogen gradient has not yet been observed. Furthermore, this is unique to the cochlear epithelium as the pSMAD1/5/9 gradient is exponential in the surrounding mesenchyme. In addition to the information-optimized linear profile, we found that while pSMAD1/5/9 is stable during this timeframe, an accompanying gradient of SOX2 shifts dynamically. Last, through joint decoding maps of pSMAD1/5/9 and SOX2, we see that there is a high-fidelity mapping between signaling activity and position in the regions that will become Kölliker’s organ and the organ of Corti. Mapping is ambiguous in the prosensory domain precursory to the outer sulcus. Altogether, this research provides new insights into the precision of early morphogenetic patterning cues in the radial cochlea prosensory domain.
